PMID- 30273167 TI - Event-Based Multiagent Consensus Control: Zeno-Free Triggering via Lp Signals. AB - In this paper, we develop some new event-triggered algorithms for achieving distributed consensus for a multiagent system that guarantees fully Zeno-free triggerings for all the agents. In the proposed framework, each agent updates its control input only at its own triggering instants by using local measurements (i.e., relative states) with respect to neighboring agents, and such local measurements can be done in a local coordinate frame. For all agents, a positive Lp signal function is embedded in the event detector functions, which aims to avoid the possible comparison of an event error term to a zero threshold that may happen in a zero-crossing scenario. We further propose a Zeno-free self-triggered algorithm to achieve multiagent consensus, which enables discrete-time measurements and thus avoids continuous measurements between the neighboring agents. We also show that the proposed event-based consensus algorithms guarantee less frequent triggered events in a bounded time interval compared to the conventional algorithm without Lp signals. Simulations and comparisons are provided to validate the performance and effectiveness of the proposed event based consensus schemes.

AB - This paper proposes an ensemble decision approach which combines global and local features of e-mails together to detect spam effectively. In the proposed method, a special feature construction method named term space partition (TSP) is utilized to divide the whole term space into several subspaces and adopt different feature construction strategies on each of them, respectively. This method can make each term play a distinct and important role when conducting detection. This method is utilized and extended by introducing the sliding window technique to extract local features from e-mails. The global classifier and local classifiers are constructed on a global feature vector set and local feature vector sets, respectively, and together make the ensemble decision by adopting the voting technique. The principles of the TSP-based approach and mechanism of the ensemble decision method are presented in detail. Five different and standard benchmark corpora are applied to experiments for performance evaluation of this proposed method. Comprehensive experimental results show that the proposed method brings significant performance improvement and better robustness on the basis of the TSP-based approach. In addition, the proposed method outperforms the current prevalent and state-of-the-art approaches, especially when a comprehensive consideration of performance, efficiency, and robustness is taken. This endows it with flexible capability and adaptivity in the real-world applications. PMID- 30273169 TI - SCH-GAN: Semi-Supervised Cross-Modal Hashing by Generative Adversarial Network. AB - Cross-modal hashing maps heterogeneous multimedia data into a common Hamming space to realize fast and flexible cross-modal retrieval. Supervised cross-modal hashing methods have achieved considerable progress by incorporating semantic side information. However, they heavily rely on large-scale labeled cross-modal training data which are hard to obtain, since multiple modalities are involved. They also ignore the rich information contained in the large amount of unlabeled data across different modalities, which can help to model the correlations between different modalities. To address these problems, in this paper, we propose a novel semi-supervised cross-modal hashing approach by generative adversarial network (SCH-GAN). The main contributions can be summarized as follows: 1) we propose a novel generative adversarial network for cross-modal hashing, in which the generative model tries to select margin examples of one modality from unlabeled data when given a query of another modality (e.g., giving a text query to retrieve images and vice versa). The discriminative model tries to distinguish the selected examples and true positive examples of the query. These two models play a minimax game so that the generative model can promote the hashing performance of the discriminative model and 2) we propose a reinforcement learning-based algorithm to drive the training of proposed SCH-GAN. The generative model takes the correlation score predicted by discriminative model as a reward, and tries to select the examples close to the margin to promote a discriminative model. Extensive experiments verify the effectiveness of our proposed approach, compared with nine state-of-the-art methods on three widely used datasets. PMID- 30273170 TI - Multipoint Rendezvous in Multirobot Systems. AB - Multirobot rendezvous control and coordination strategies have garnered significant interest in recent years because of their potential applications in decentralized tasks. In this paper, we introduce a coordinate-free rendezvous control strategy to enable multiple robots to gather at different locations (dynamic leader robots) by tracking their hierarchy in a connected interaction graph. A key novelty in this strategy is the gathering of robots in different groups rather than at a single consensus point, motivated by autonomous multipoint recharging and flocking control problems. We show that the proposed rendezvous strategy guarantees convergence and maintains connectivity while accounting for practical considerations such as robots with limited speeds and an obstacle-rich environment. The algorithm is distributed and handles minor faults such as a broken immobile robot and a sudden link failure. In addition, we propose an approach that determines the locations of rendezvous points based on the connected interaction topology and indirectly optimizes the total energy consumption for rendezvous in all robots. Through extensive experiments with the Robotarium multirobot testbed, we verified and demonstrated the effectiveness of our approach and its properties. PMID- 30273171 TI - Alignment-Supervised Bidimensional Attention-Based Recursive Autoencoders for Bilingual Phrase Representation. AB - Exploiting semantic interactions between the source and target linguistic items at different levels of granularity is crucial for generating compact vector representations for bilingual phrases. To achieve this, we propose alignment supervised bidimensional attention-based recursive autoencoders (ABattRAE) in this paper. ABattRAE first individually employs two recursive autoencoders to recover hierarchical tree structures of bilingual phrase, and treats the subphrase covered by each node on the tree as a linguistic item. Unlike previous methods, ABattRAE introduces a bidimensional attention network to measure the semantic matching degree between linguistic items of different languages, which enables our model to integrate information from all nodes by dynamically assigning varying weights to their corresponding embeddings. To ensure the accuracy of the generated attention weights in the attention network, ABattRAE incorporates word alignments as supervision signals to guide the learning procedure. Using the general stochastic gradient descent algorithm, we train our model in an end-to-end fashion, where the semantic similarity of translation equivalents is maximized while the semantic similarity of nontranslation pairs is minimized. Finally, we incorporate a semantic feature based on the learned bilingual phrase representations into a machine translation system for better translation selection. Experimental results on NIST Chinese-English and WMT English-German test sets show that our model achieves substantial improvements of up to 2.86 and 1.09 BLEU points over the baseline, respectively. Extensive in depth analyses demonstrate the superiority of our model in learning bilingual phrase embeddings. PMID- 30273172 TI - Products of Generalized Stochastic Matrices With Applications to Consensus Analysis in Networks of Multiagents With Delays. AB - Product theory of stochastic matrices provides a powerful tool in the consensus analysis of discrete-time multiagent systems. However, the classic theory cannot deal with networks with general coupling coefficients involving negative ones, which have been discussed only in very few papers due to the technicalities involved. Motivated by these works, here we developed some new results for the products of matrices which generalize that of the classical stochastic matrices by admitting negative entries. Particularly, we obtained a generalized version of the classic Hajnal inequality on this generalized matrix class. Based on these results, we proved some convergence results for a class of discrete-time consensus algorithms with time-varying delays and general coupling coefficients. At last, these results were applied to the analysis of a class of continuous-time consensus algorithms with discrete-time controller updates in the existence of communication/actuation delays. PMID- 30273173 TI - Event-Triggered Adaptive Tracking Control for Multiagent Systems With Unknown Disturbances. AB - This paper considers the event-triggered tracking control problem of nonlinear multiagent systems with unknown disturbances. The event-triggering mechanism is considered in the controller update, which decreases the amount of communication and reduces the frequency of the controller update in practice. By designing a disturbance observer, the unknown external disturbances are estimated. Moreover, a part of adaptive parameters are only dependent on the number of followers, which weakens the computational burden. It is shown that all the signals are bounded, and the consensus tracking errors are located in a small neighborhood of the origin based on the Lyapunov stability theory and backstepping approach. Finally, the effectiveness of the approach proposed in this paper is proved by simulation results. PMID- 30273174 TI - Consensus-Based Odor Source Localization by Multiagent Systems. AB - This paper presents an investigation of the task of localizing an unknown source of an odor by heterogeneous multiagent systems. A hierarchical cooperative control strategy has been proposed as a potential candidate to solve the problem. The agents are driven into consensus as soon as the information about the location of source is acquired. The controller has been designed in a hierarchical manner of group decision making, agent path planning, and robust control. In group decision making, the particle swarm optimization algorithm has been used along with the information of the movement of odor molecules to predict the odor source location. Next, a trajectory has been mapped using this predicted location of source, and the information is passed to the control layer. A variable structure control has been used in the control layer due to its inherent robustness and disturbance rejection capabilities. Cases of movement of agents toward the source under consensus and parallel formation have been discussed. The efficacy of the proposed scheme has been confirmed by simulations. PMID- 30273175 TI - Average Quasi-Consensus Algorithm for Distributed Constrained Optimization: Impulsive Communication Framework. AB - This paper presents the impulsive average quasi-consensus algorithm for distributed constrained convex optimization. First, the constrained optimization problem can be transformed into an unconstrained problem using the interior point method, and then a distributed algorithm is modeled by means of impulsive differential equation. In the framework of the continuous-time gradient method and algebraic graph theory, each agent can deal with one local objective function with local constraints. At the impulsive instants, each agent can communicate with its neighboring agents over the network. Under certain conditions, the impulsive average quasi-consensus is achieved. It is shown that the state of average quasi-consensus is the optimal solution of the aforementioned unconstrained optimization problem, and the state of each agent can also reach the neighborhood of the optimal solution. Finally, two numerical examples show the effectiveness of the proposed impulsive average quasi-consensus algorithm. Moreover, the feasibility of the approach is verified by an application to one sensor network localization problem. PMID- 30273176 TI - Relative Degrees and Implicit Function-Based Control of Discrete-Time Noncanonical Form Neural Network Systems. AB - This paper studies the relative degrees of discrete-time neural network systems in a general noncanonical form, and develops a new feedback control scheme for such systems, based on implicit function theory and feedback linearization. After time-advance operation on output of such systems, the output dynamics nonlinearly depends on the control input. To address this issue, we use implicit function theory to define the relative degrees, and to establish a normal form. Then, an implicit function equation solution-based control scheme and an iterative solution-based control scheme are proposed, which ensure not only the closed-loop stability but also the output tracking for the controlled plant. An adaptive control framework for the controlled plant with uncertainties is also presented to illustrate the basic design procedure. The simulation results are given to demonstrate the desired system performance. PMID- 30273177 TI - Cooperative Control of Multiple Nonlinear Benchmark Systems Perturbed by Second Order Moment Processes. AB - This paper studies the cooperative control problem of multiple nonlinear benchmark systems perturbed by second-order moment processes. The nonlinear benchmark system consists of a moving car and a rolling ball in oscillating surroundings. When the leader is only accessible to a small part of the followers in a directed graph, a new vectorial backstepping method is proposed for the design of distributed cooperative control laws. By using stochastic analysis techniques and algebra graph theory, it is shown that the cooperative control problem under consideration is solvable. Specifically, the errors between the followers' outputs and the leader's output can be made arbitrarily small while keeping all states of the closed-loop system bounded in probability. Finally, the effectiveness of the proposed control scheme is demonstrated through a simulation example. PMID- 30273178 TI - Event-Based Control for Networked T-S Fuzzy Systems via Auxiliary Random Series Approach. AB - This paper presents an auxiliary random series approach to model the effect of network induced problems, such as data losses and transmission delay subject to event-based communication scheme for nonlinear continuous time systems. T-S fuzzy model is employed to describe the nonlinear systems. In order to save the bandwidth and energy, we introduce the event-triggered mechanism to reduce the number of data for transmission and computation. Thus, it is necessary to consider the influence of data losses, data disorder, and transmission delay since the transmitted data packets become more important. Consequently, it is very complicated to analyze the performance of such networked system and one of the most difficult part, in the authors' opinion, is to construct the mathematical model of closed-loop systems. In this paper, we present an auxiliary random series approach to describe the data transmitted in the system, and therefore, the closed-loop systems can be obtained. Associated with a tailor-made Lyapunov-Krasovskii functional, the stability analysis is processed and a fuzzy controller is designed. Asynchronous membership functions are considered to obtain more relaxed stability conditions. To clarify the effectiveness of the proposed method, a cart-damper-spring system is employed for simulation. PMID- 30273179 TI - Enhancing Gaussian Estimation of Distribution Algorithm by Exploiting Evolution Direction With Archive. AB - As a typical model-based evolutionary algorithm, estimation of distribution algorithm (EDA) possesses unique characteristics and has been widely applied in global optimization. However, the commonly used Gaussian EDA (GEDA) usually suffers from premature convergence, which severely limits its search efficiency. This paper first systematically analyzes the reasons for the deficiency of traditional GEDA, then tries to enhance its performance by exploiting the evolution direction, and finally develops a new GEDA variant named EDA2. Instead of only utilizing some good solutions produced in the current generation to estimate the Gaussian model, EDA2 preserves a certain number of high-quality solutions generated in the previous generations into an archive and employs these historical solutions to assist estimating the covariance matrix of Gaussian model. By this means, the evolution direction information hidden in the archive is naturally integrated into the estimated model, which in turn can guide EDA2 toward more promising solution regions. Moreover, the new estimation method significantly reduces the population size of EDA2 since it needs fewer individuals in the current population for model estimation. As a result, a fast convergence can be achieved. To verify the efficiency of EDA2, we tested it on a variety of benchmark functions and compared it with several state-of-the-art EAs. The experimental results demonstrate that EDA2 is efficient and competitive. PMID- 30273180 TI - A Random Forest-Assisted Evolutionary Algorithm for Data-Driven Constrained Multiobjective Combinatorial Optimization of Trauma Systems. AB - Many real-world optimization problems can be solved by using the data-driven approach only, simply because no analytic objective functions are available for evaluating candidate solutions. In this paper, we address a class of expensive data-driven constrained multiobjective combinatorial optimization problems, where the objectives and constraints can be calculated only on the basis of a large amount of data. To solve this class of problems, we propose using random forests (RFs) and radial basis function networks as surrogates to approximate both objective and constraint functions. In addition, logistic regression models are introduced to rectify the surrogate-assisted fitness evaluations and a stochastic ranking selection is adopted to further reduce the influences of the approximated constraint functions. Three variants of the proposed algorithm are empirically evaluated on multiobjective knapsack benchmark problems and two real-world trauma system design problems. Experimental results demonstrate that the variant using RF models as the surrogates is effective and efficient in solving data-driven constrained multiobjective combinatorial optimization problems. PMID- 30273181 TI - Containment Control for General Second-Order Multiagent Systems With Switched Dynamics. AB - This paper investigates the distributed containment control problem for a class of general second-order multiagent systems with switched dynamics, which is composed of a continuous-time (CT) subsystem and a discrete-time (DT) subsystem. For this switched multiagent system under fixed directed topology, a distributed containment control protocol is proposed for each follower based on the relative local measurements of neighboring followers and leaders. Some necessary and sufficient conditions are derived under the condition that the network topology contains a directed spanning forest, and these conditions ensure that the general second-order containment control problem can be solved under arbitrary CT-DT switching. If the general second-order system is reduced to the double integrator system, some simpler containment conditions are presented. Furthermore, the similar results are also obtained under switching directed topology. Finally, some simulation examples are presented to show the efficiency of the theoretical results. PMID- 30273182 TI - MicroRNA-195 reverses the resistance to temozolomide through targeting cyclin E1 in glioma cells. AB - Glioma is the most common malignant tumor of the central nervous system with poor survival. Temozolomide (TMZ) is the first-line chemotherapy drug for initial and recurrent glioma treatment with a relatively good efficacy, which exerts its antitumor effects mainly through cell death induced by DNA double-strand breaks in the G1 and S phases. However, endogenous or acquired resistance to TMZ limits glioma patients' clinical outcome and is also an important cause of glioma replase. MicroRNA-195 (miR-195) plays an important role in the regulation of G1 phase/S-phase transition, DNA damage repair, and apoptosis of tumor cells. We found that miR-195 expression was significantly decreased in TMZ-resistant glioma cells induced with TMZ and correlated to the resistance index negatively. Also, the exogenous expression of miR-195 reversed TMZ resistance and induced the apoptosis of TMZ-resistant glioblastoma cells. Further bioinformatics analysis showed cyclin E1 (CCNE1) was a potential target gene of miR-195. Knockdown of CCNE1 partially reversed the effect of decreased miR-195 on TMZ resistance. The data from The Cancer Genome Atlas - Cancer Genome further suggested that hsa-miR 195 could negatively regulate the expression of CCNE1 in glioma. In conclusion, miR-195 reverses the resistance to TMZ by targeting CCNE1 in glioma cells and it could act as a potential target for treatment in glioma with TMZ resistance.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30273183 TI - Long-term clinical outcomes after treatment of stent restenosis with two drug coated balloons. AB - BACKGROUND: Treatment of in-stent restenosis (ISR) is still a clinical challenge in interventional cardiology. Paclitaxel-coated balloons (PCBs) are an attractive therapeutic option for ISR. There are several different types of PCBs available for percutaneous coronary intervention, but to date, comparative data between different types of PCBs for the treatment of ISR are scarce. PATIENTS AND METHODS: This single centre, nonrandomized, retrospective study under real-world condition included 194 patients with 194 ISR treated by repeat percutaneous coronary intervention with PCBs. The primary end point was major adverse cardiac events (MACEs), defined as cardiac death, myocardial infarction and need for target lesion revascularization (TLR) at 1 year. Secondary end points were MACE and TLR at long-term follow-up. RESULTS: Baseline clinical and angiographic parameters were comparable between the two groups. Patients in the iopromide based PCB and butyryl-tri-hexyl citrate (BTHC)-PCB groups were followed up for 32.2+/-20.5 and 24.2+/-13.3 months, respectively (P=0.001). MACEs at 1-year follow-up were 15.0 and 15.8% (P=0.879) for the BTHC-PCB and iopromide-based PCB groups, respectively. TLR, myocardial infarction and cardiac death for BTHC-PCB versus iopromide-based PCB at 1-year follow-up were 9.6 versus 11.8%, P=0.622; 5.3 versus 3.9%, P=0.640; and 5.3 versus 3.9%, P=0.640, respectively. If complete follow-up periods were included in the analysis, BTHC-PCB and iopromide-based PCB had comparable rates of MACE (P=0.835) and TLR (P=0.792). CONCLUSION: BTHC-PCB and iopromide-based PCB had comparable rates of MACE and TLR for the treatment of ISR at 1-year and long-term follow-up.

PMID- 30273185 TI - Comparison of Pain-reducing Effect After Selective Nerve Root Block According to the Type of Lumbar Foraminal Stenosis. AB - STUDY DESIGN: This was a nonrandomized controlled cohort study (level 3). OBJECTIVE: This study was designed to compare the differences in clinical features among patients with various degrees of lumbar foraminal stenosis (LFS), and the therapeutic effect of selective nerve root block (SNRB). SUMMARY OF BACKGROUND DATA: Symptomatic improvement rate was lower in grade IV (0.377) than in other grades (1T: 0.612, 2:0.527, 3:0.551), with statistical significance (P=0.03). PATIENTS AND METHODS: A total of 233 patients with radiating pain, concurrent with neurological and radiologic findings, were assigned to receive SNRB for at least 1 level, and screened for >=6 months. The degree of foraminal stenosis was classified by perineural fat obliteration, and the degree of radiating pain was assessed by visual analog scale. After SNRBs were performed, symptomatic improvement was assessed after 2, 12, and 24 weeks after injection. RESULTS: There were no significant differences in visual analog scale with regard to the degree of stenosis. Improvements were significantly higher after 2 weeks (P=0.030), and there were no significant differences in symptomatic improvement rates over time except LFS grade 1V. At 2 weeks after injection, there was no significant difference in the extent of symptomatic improvement between the grades. At 12 and 24 weeks after injection, patients with LFS grade 1T, 2, 3 showed significantly higher symptomatic improvement rates than patients with LFS grade 1V. CONCLUSIONS: Among the patients with LFS, SNRB reduced pain by 51% after 2 weeks. At after 12 weeks, SNRBs were more effective in patients with LFS grade 1T, 2, 3, compared with patients with grade 1V. All patients showed persistent symptomatic relief, whereas those with grade 1T showed a reduced degree of symptomatic relief after 2 weeks. PMID- 30273186 TI - Surgical Treatment of Dystrophic Scoliosis in Neurofibromatosis Type 1: Outcomes and Complications. AB - STUDY DESIGN: This is a retrospective cohort study. OBJECTIVE: To investigate surgical outcomes and instrumentation-related complications (IRCs) of dystrophic scoliosis associated with neurofibromatosis type 1 (NF-1). SUMMARY OF BACKGROUND DATA: Surgical management, including the growing rod technique and early definitive fusion, has been recommended to avoid progression of NF-1 scoliosis. However, no study has investigated the outcomes and complications of different surgical interventions. MATERIALS AND METHODS: We performed a retrospective review of a cohort of 59 patients diagnosed with NF-1 dystrophic scoliosis and treated surgically. All clinical and radiographic data within a 3-year follow-up period were collected. The patients were divided into 2 groups according to the surgical procedure used: those who underwent initial fusion surgery were assigned to group A (n=32) and those who underwent growing rod surgery to group B (n=27). RESULTS: Patients in group A were older than those in group B at the initial surgery (10.4 vs. 5.8 y; P<0.001). There was no difference in the sex ratio, preoperative Cobb angle, or preoperative kyphosis angle between the 2 groups (P>0.05). The correction rate of the main curve Cobb angle was higher in group A than B (55.1% vs. 42.4%; P<0.05). The incidence of IRC was higher in group B than A (48.1% vs. 12.5%; P<0.05). Complications in group A comprised 1 case of screw pullout, 1 case of rod breakage, 1 case of adding-on phenomenon, and 1 case of proximal junctional kyphosis. Complications in group B comprised 5 cases of adding-on phenomenon, 4 cases of trunk shift, 3 cases of curve progression, 1 case of rod breakage, and 1 case of cap loosening. CONCLUSIONS: The use of growing rod effectively controls the spinal deformity and facilitates growth of the spine. Compared with fusion surgery, however, growing rod surgery yields a higher incidence of IRCs and lower corrective rate for scoliosis associated with NF-1. PMID- 30273187 TI - Relation Between Infant Microbiota and Autism?: Results from a National Cohort Sibling Design Study. AB - BACKGROUND: Hypotheses concerning adverse effects of changes in microbiota have received much recent attention, but unobserved confounding makes them difficult to test. We investigated whether surrogate markers for potential adverse microbiota change in infancy affected autism risk, addressing unobserved confounding using a sibling study design. METHODS: This is a population-based, prospective cohort study including all singleton live births in Denmark from 1997 to 2010. The exposure variables were cesarean delivery and antibiotic use in the first 2 years of life. The outcome was a subsequent autism diagnosis. We used the between- and within-sibling model and compared it with sibling-stratified Cox models and simpler standard Cox models that ignored sibship. RESULTS: Of our study population including 671,606 children, who were followed for up to 15 years (7,341,133 person-years), 72% received antibiotics, 17.5% were delivered by cesarean, and 1.2% (8,267) developed autism. The standard Cox models predicted that both cesarean (compared with vaginal) delivery and antibiotics increased the risk of autism. In the sibling-stratified Cox model, only broader spectrum antibiotics were associated with increased risk of autism: hazard ratio (HR) = 1.16 (95% confidence interval = 1.01, 1.36). The between-within model estimated no exposure effects: intrapartum cesarean HR = 1.06 (0.89, 1.26); prelabor cesarean HR = 0.97 (0.83, 1.15); exclusively penicillin HR = 1.05 (0.93, 1.18); and broader spectrum antibiotics HR = 1.05 (0.95, 1.16). CONCLUSIONS: The between within model rendered more precise estimates than sibling-stratified Cox models, and we believe that it also provided more valid estimates. Results from these preferred models do not support a causal relation between antibiotic treatment during infancy, cesarean delivery, and autism. See video abstract at, http://links.lww.com/EDE/B432.

AB - Urinary retention is a well-documented adverse effect of antipsychotic medications and is thought to be mediated by anticholinergic, adrenergic, and other neurotransmitter effects. Whereas urinary retention has been reported with typical and some atypical antipsychotics, there have been no reports of urinary retention with the novel antipsychotic cariprazine. We report on a case of urinary retention associated with cariprazine. Possible mechanisms for this adverse effect are discussed.

PMID- 30273188 TI - Cumulative Human Immunodeficiency Viremia, Antiretroviral Therapy, and Incident Myocardial Infarction. AB - BACKGROUND: People living with HIV are at risk of increased myocardial infarction (MI). Cumulative HIV viral load (VL) has been proposed as a better measure of HIV inflammation than other measures of VL, like baseline VL, but its associations with MI are not known. METHODS: The multisite Centers for AIDS Research Network of Integrated Clinical Systems (CNICS) cohort includes clinical data and centrally adjudicated MI with distinction between atheroembolic MI (type 1) and MI related to supply-demand mismatch (type 2). We examined CNICS participants who were not on antiretroviral therapy (ART) at enrollment. Cumulative VL (copy-days of virus) from 6 months after enrollment was estimated with a time-weighted sum using the trapezoidal rule. We modeled associations of cumulative and baseline VL with MI by type using marginal structural Cox models. We contrasted the 75% percentile of the VL distribution with the 25% percentile. RESULTS: Among 11,324 participants, 218 MIs occurred between 1996 and 2016. Higher cumulative VL was associated with risk of all MI (hazard ratio [HR] = 1.72; 95% confidence interval [CI] = 1.26, 2.36), type 1 MI (HR = 1.23; 95% CI = 0.78, 1.96), and type 2 MI (HR = 2.52; 95% CI = 1.74, 3.66). While off ART, cumulative VL had a stronger association with type 1 MI (HR = 2.13; 95% CI = 1.15, 3.94) than type 2 MI (HR = 1.25; 95% CI = 0.70, 2.25). Baseline VL was associated with all MI (HR = 1.60; 95% CI = 1.28, 2.01), type 1 MI (HR = 1.73; 95% CI = 1.26, 2.38), and type 2 MI (HR = 1.51; 95% CI = 1.10, 2.08). CONCLUSIONS: Higher cumulative and baseline VL is associated with all MI, with a particularly strong association between cumulative VL and type 2 MI. PMID- 30273191 TI - Fludarabine-Induced Posterior Reversible Encephalopathy Syndrome in a Pediatric Patient With beta-Thalassemia: Case Report and Literature Review. AB - Posterior reversible encephalopathy syndrome is a disorder of reversible subcortical vasogenic brain edema in the context of different diseases or exposure to cytotoxic drugs such as fludarabine. We present the case of a pediatric patient with beta-thalassemia who develops a fludarabine-induced posterior reversible encephalopathy while he received an induction regimen to achieve an allogenic hematopoietic cell transplantation. The clinical presentation consists in altered mental state, headache, status epilepticus, visual disturbance, and hypertension. His treatment was carried out with the suspension of the medication and the control of hypertension and status epilepticus; the final outcome was positive without additional complications. There are published reports about fludarabine toxicity in the central nervous system with different doses of the drug in different clinical context. We also made a review of the literature available and conclude that fludarabine is not an extraordinary cause of posterior reversible encephalopathy syndrome. PMID- 30273192 TI - Increased Risk of Ischemic Stroke in Multiple Myeloma Associated With Lenalidomide Treatment: A Case Report and Review of the Literature. AB - OBJECTIVE: The aim of the study was to illustrate the increased risk of ischemic stroke in the context of multiple myeloma (MM) under treatment with lenalidomide combined with dexamethasone. METHODS: This is a case report and literature review. RESULTS: A 62-year-old woman diagnosed with relapsed MM under treatment with lenalidomide and dexamethasone presented with acute onset disorientation, disturbed behavior, and aphasia. Cranial computed tomography scan revealed an acute cerebral infarction in the left middle cerebral artery territory, and brain magnetic resonance imaging showed additional silent ischemic lesions in other arterial territories. Common stroke etiologies were excluded after an extensive study, leading to a final diagnosis of cerebral infarction of uncommon cause probably related to MM and treatment with lenalidomide plus dexamethasone. A literature review provided 84 reports from the license holder, 2 more cases of stroke in patients with MM receiving lenalidomide and a recurrent stroke in a patient experiencing polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS syndrome) treated with lenalidomide. CONCLUSIONS: Our case exemplifies the need to raise awareness about the risk of ischemic stroke associated with MM that might be increased by treatment with lenalidomide and to establish consistent recommendations regarding thromboprophylaxis to reduce comorbidities and mortality in these patients. PMID- 30273193 TI - Geometric Properties of Donor Corneas After Mechanical Trephination in Deep Anterior Lamellar Keratoplasty. AB - PURPOSE: To evaluate the geometry of donor corneal buttons after mechanical trephination and to determine whether there were any possible variables that could influence the accuracy of cutting corneal buttons in deep anterior lamellar keratoplasty. METHODS: This cross-sectional study included 85 sclerocorneal buttons that were transplanted during deep anterior lamellar keratoplasty. Donor corneas were punched from the posterior surface. Photographs that most clearly represented the entire edges of the donor corneas were taken from the punched corneas and systematically analyzed using ImageJ software. The univariate analyses were used to investigate the influence of potential variables on the precision and roundness of the donor cut. RESULTS: The epithelial side of the grafts was significantly larger than the posterior side in diameter, perimeter, and area. The perimeter and area of the donor posterior surface and the trephine used for punching the grafts were the same, whereas the epithelial side had a significantly larger perimeter and area than those of the trephine. Graft roundness varied from 0.78 to 1.0 at the epithelial side and from 0.77 to 1.0 at the posterior side. The roundness of the scleral spur, which represented the shape of the donor cornea, was identified as the main predictor of the roundness of the donor cut (P < 0.001). CONCLUSIONS: The donor buttons after mechanical trephination from the posterior surface may not be circular and of the intended diameter; the epithelial surface dimensions were significantly larger than the posterior surface and trephine dimensions. The roundness of the punched graft was primarily affected by the roundness of the cornea before trephination. PMID- 30273194 TI - Age and CD20 Expression Are Significant Prognostic Factors in Human Herpes Virus 8-negative Effusion-based Lymphoma. AB - Human herpes virus-8 (HHV-8)-negative effusion-based lymphoma (HHV-8-negative EBL) can be distinguished from primary effusion lymphoma based on clinical and pathologic findings. Although the morphology between the 2 is similar and they both originate from body cavities with serous effusions and are characterized by lack of tumor masses, HHV-8-negative EBL generally occurs in older patients, and has favorable response to therapy and better prognosis than primary effusion lymphoma. However, no systematic studies have investigated prognostic factors in patients with HHV-8-negative EBL. In this report, clinical and pathologic characteristics of 67 cases of HHV-8-negative EBL, including 2 of our own cases, were analyzed. Univariate analyses revealed older age (70 y and above), Japanese ethnicity, pericardial effusion, CD20 expression, and chemotherapy with rituximab were significantly favorable prognostic factors. Peritoneal effusion was identified as an unfavorable prognostic factor. In the multivariate analysis, age and CD20 expression were independent prognostic factors (P=0.013 and 0.003, respectively). A past history of induced fluid overload, hepatitis C viral infection, and peritoneal effusion were significantly correlated with patients aged below 70 years, while pericardial and pleural effusions were significantly correlated with patients aged 70 years and above. A comparison of cases with and without CD20 expression revealed that Japanese ethnicity and pericardial effusion were significantly correlated with CD20 expression, whereas a past history of induced fluid overload and peritoneal effusion were significantly correlated with the absence of CD20. We concluded that older age and CD20 expression are significant and favorable independent prognostic factors of HHV-8-negative EBL. PMID- 30273195 TI - Uterine Tumor Resembling Ovarian Sex Cord Tumor: A Distinct Entity Characterized by Recurrent NCOA2/3 Gene Fusions. AB - Uterine tumor resembling ovarian sex-cord tumor (UTROSCT) is a rare and distinctive neoplasm of unclear histogenesis, and uncertain malignant potential. These neoplasms morphologically resemble sex-cord stromal tumors of the ovary, and possess a polyphenotypic immunophenotype. Their molecular pathogenesis has yet to be elucidated; notably, however, tumors lack alterations found in other uterine tumors bearing sex-cord-like differentiation, such as endometrial stromal sarcoma. Following identification of an index patient with an ESR1-NCOA3 fusion gene by RNA-sequencing, we undertook a retrospective review for additional cases of UTROSCT. We identified a total of 4 patients, with an average age of 53 years (range, 38 to 68 y). RNA-sequencing was performed in all cases, revealing an ESR1 NCOA3 fusion in 2 cases and one case each with related ESR1-NCOA2 and GREB1-NCOA2 fusions. Each of the tumors showed histologic and an immunophenotype features within the previously reported spectrum of UTROSCT; interestingly, one case contained prominent spindle cell fascicles and another was largely comprised of sheets of small round cells. Our results demonstrate UTROSCT are defined by recurrent fusions involving NCOA2 or NCOA3, a finding that is directly amenable to diagnostic evaluation. This study confirms UTROSCT is molecularly distinct from endometrial stromal sarcoma, and raises intriguing new questions into the pathogenesis of these neoplasms and possible relationship with other NCOA fusion positive uterine tumors. PMID- 30273196 TI - Heterogeneity of Fibrosis in Liver Biopsies of Patients With Heart Failure Undergoing Heart Transplant Evaluation. AB - Liver biopsies are commonly performed in heart transplant candidates to confirm congestive hepatopathy (CH) and to assess the degree of fibrosis. Heterogeneity of fibrosis is frequent in CH, making it difficult to stage fibrosis. In this study, we evaluated the prevalence of heterogeneity of fibrosis and nodular regenerative hyperplasia (NRH) in liver biopsies with CH secondary to heart failure. Fifty liver biopsies with CH secondary to heart failure were reviewed. The fibrosis was scored on trichrome stain as follows: stage 0 for no fibrosis, stage 1 for zone 3 fibrosis, stage 2 for zone 3 and portal fibrosis, stage 3 for bridging fibrosis, and stage 4 for cirrhosis. Both stage 3 and stage 4 fibrosis were classified as advanced fibrosis. A predominant pattern of fibrosis and a secondary pattern of fibrosis, defined as a different stage of fibrosis seen in at least 10% of the biopsy material, if present, were recorded. A biopsy was considered to show heterogenous fibrosis if there was at least a 2 stage difference between the predominant and secondary patterns. Thirteen biopsies (26%) showed heterogenous fibrosis. Sixteen biopsies (32%) showed some evidence of advanced fibrosis: 5 had uniform advanced fibrosis, 4 had predominant pattern of advanced fibrosis, and advanced fibrosis was focal in 7 biopsies from 6 patients. NRH-type changes were seen in 9 of 50 biopsies (18%). In conclusion, our study showed heterogenous fibrosis in the liver biopsy of a quarter of patients with CH due to heart failure, highlighting the limitations of fibrosis assessment in the biopsies, and suggests that correlation with the complete clinical information is essential for management decisions. PMID- 30273197 TI - SF3B1, NRAS, KIT, and BRAF Mutation; CD117 and cMYC Expression; and Tumoral Pigmentation in Sinonasal Melanomas: An Analysis With Newly Found Molecular Alterations and Some Population-based Molecular Differences. AB - Sinonasal melanomas encompass melanoma arising in the nasal cavity and paranasal sinuses. Despite recent advances in tumor genomics, correlation between mutational status and protein expression with prognosis and tumor pigmentation has not been carried out in sinonasal melanomas. Ninety-five sinonasal melanomas from 95 patients were included. As per univariate analyses, age was the only variable that significantly correlated with progression-free survival. SF3B1, NRAS, KIT, and BRAF mutations were documented in 7% (5/72), 22% (16/72), 22% (16/72), and 8% (6/72) of cases, respectively. Comutation was detected in 6 cases: NRAS and KIT in 2 cases; NRAS and BRAF in 2 cases; SF3B1, KIT, and BRAF in one case; and SF3B1, NRAS, and KIT in one case. Correlations approaching statistical significance were observed between BRAF mutation status and poorer overall survival and progression-free survival (log-rank P-values=0.054 and 0.061). Increased CD117 expression (33%, 29/88) and decreased nuclear cMYC expression (40%, 39/84) significantly correlated with cytoplasmic pigmentation. Several SF3B1, NRAS, and KIT mutations not previously documented in sinonasal melanomas were detected in our series, suggesting a potential role for targeted therapies. A similar frequency of SF3B1, NRAS, and KIT mutations was noted in Asian cases, whereas NRAS, KIT, and BRAF mutations were predominant in the United States and European cases; however, the number of included cases was small. The significant association between CD117 and cMYC expression with increased cytoplasmic pigmentation in our series suggests that the pigmented morphologic appearance of sinonasal melanomas could be attributed to the underlying oncogenic mutations and metabolic interaction. PMID- 30273198 TI - The Hexavalent CD40 Agonist HERA-CD40L Induces T-Cell-mediated Antitumor Immune Response Through Activation of Antigen-presenting Cells. AB - CD40 ligand (TNFSF5/CD154/CD40L), a member of the tumor necrosis factor (TNF) superfamily is a key regulator of the immune system. The cognate receptor CD40 (TNFRSF5) is expressed broadly on antigen-presenting cells and many tumor types, and has emerged as an attractive target for immunologic cancer treatment. Most of the CD40 targeting drugs in clinical development are antibodies which display some disadvantages: their activity typically depends on Fcgamma receptor-mediated crosslinking, and depletion of CD40-expressing immune cells by antibody-dependent cellular cytotoxicity compromises an efficient antitumor response. To overcome the inadequacies of antibodies, we have developed the hexavalent receptor agonist (HERA) Technology. HERA compounds are fusion proteins composed of 3 receptor binding domains in a single chain arrangement, linked to an Fc-silenced human IgG1 thereby generating a hexavalent molecule. HERA-CD40L provides efficient receptor agonism on CD40-expressing cells and, importantly, does not require FcgammaR-mediated crosslinking. Strong activation of NFkappaB signaling was observed upon treatment of B cells with HERA-CD40L. Monocyte treatment with HERA CD40L promoted differentiation towards the M1 spectrum and repolarization of M2 spectrum macrophages towards the M1 spectrum phenotype. Treatment of in vitro co cultures of T and B cells with HERA-CD40L-triggered robust antitumor activation of T cells, which depended upon direct interaction with B cells. In contrast, bivalent anti-CD40 antibodies and trivalent soluble CD40L displayed weak activity which critically depended on crosslinking. In vivo, a murine surrogate of HERA CD40L-stimulated clonal expansion of OT-I-specific murine CD8 T cells and showed single agent antitumor activity in the CD40 syngeneic MC38-CEA mouse model of colorectal cancer, suggesting an involvement of the immune system in controlling tumor growth. We conclude that HERA-CD40L is able to establish robust antitumor immune responses both in vitro and in vivo. PMID- 30273199 TI - Trends of Polypharmacy and Prescription Patterns of Antidepressants in Asia. AB - PURPOSE: Little is known regarding the trend of polypharmacy in Asia. We used data from 5 Asian countries to examine the patterns of antidepressant (AD) prescription and trends of psychotropic polypharmacy over time. METHODS: We used the cross-sectional, pharmacoepidemiological data from 2004 and 2013 REAP-AD (Research on Asian Psychotropic Prescription Patterns for Antidepressants) to examine the patterns of AD prescriptions in clinical settings in China, Japan, Korea, Singapore, and Taiwan. We compared the trend in polypharmacy (ie, concomitant use of >=2 classes of psychotropic) among individuals receiving AD prescriptions in 2004 and 2013 using multivariable logistic regression models in different diagnostic categories. RESULTS: The proportion of patients with psychotropic polypharmacy decreased from 2004 to 2013 in all 3 diagnostic categories, including mood disorders (adjusted odds ratio [aOR], 0.44 [0.35 0.56]; P < 0.001), anxiety disorders (aOR, 0.58 [0.36-0.94]; P = 0.028), and psychotic disorders (aOR, 0.18 [0.05-0.60]; P = 0.006). Among individuals with AD prescriptions, concomitant use of anxiolytics (including sedative-hypnotics) decreased in patients with mood disorders (aOR, 0.34 [0.27-0.42]; P < 0.001) and anxiety disorders (aOR, 0.43 [0.27-0.67]; P < 0.001). In contrast, concomitant use of antipsychotics in patients with mood disorders increased (aOR, 1.43 [1.15 1.77]; P = 0.001), and concomitant use of mood stabilizers in patients with psychotic disorders also increased (aOR, 3.49 [1.50-8.14]; P = 0.004). CONCLUSIONS: This is the first study examining trends in psychotropic polypharmacy in East Asia. We found a generally decreasing trend of psychotropic polypharmacy in contrast to the increasing trend reported from Western countries. These findings could offer significant implications for health system reform or policy making. PMID- 30273200 TI - The Effect of Ultra-low-dose Intrathecal Naloxone on Pain Intensity After Lumbar Laminectomy With Spinal Fusion: A Randomized Controlled Trial. AB - BACKGROUND: Despite advances in pain management, several patients continue to experience severe acute pain after lumbar spine surgery. The aim of this study was to assess the safety and effectiveness of single ultra-low-dose intrathecal (IT) naloxone in combination with IT morphine for reducing pain intensity, pruritus, nausea, and vomiting in patients undergoing lumbar laminectomy with spinal fusion. MATERIALS AND METHODS: In this double-blind trial, patients scheduled for lumbar laminectomy with spinal fusion were randomly assigned to receive single ultra-low-dose IT naloxone (20 MUg) and IT morphine (0.2 mg) (group M+N) or IT morphine (0.2 mg) alone (group M). The severity of postoperative pain, pruritus and nausea, and frequency of vomiting were assessed at recovery from anesthesia and, subsequently, at 1, 3, 6, 12, and 24 hours postoperatively using an 11-point (0-10) visual analogue scale. RESULTS: A total of 77 patients completed the study, and there were significant differences in postoperative pain, pruritus, and nausea visual analogue scale between the groups (P<0.05). After adjusting for body mass index and surgery duration, IT naloxone administration reduced the pain score (coefficient=1.84; 95% confidence interval [CI], 1.05-2.63; P<0.001), and the scores of pruritus and nausea (coefficient=0.9; 95% CI, 0.44-1.37; P<0.001 and coefficient=0.71; 95% CI, 0.12 1.31; P=0.02, respectively) compared with IT morphine alone. No serious adverse effects were observed. CONCLUSIONS: The addition of ultra-low-dose IT naloxone to IT morphine provides excellent postoperative pain management and effectively controls pruritus and nausea in patients undergoing laminectomy with spinal fusion. PMID- 30273201 TI - A Survey On Fever Monitoring and Management in Patients With Acute Brain Injury: The SUMMA Study. AB - BACKGROUND: Fever is common in patients with acute brain injury and worsens secondary brain injury and clinical outcomes. Currently, there is a lack of consensus on the definition of fever and its management. The aims of the survey were to explore: (a) fever definitions, (b) thresholds to trigger temperature management, and (c) therapeutic strategies to control fever. MATERIALS AND METHODS: A questionnaire (26 items) was made available to members of the European Society of Intensive Care Medicine via its website between July 2016 and December 2016. RESULTS: Among 231 respondents, 193 provided complete responses to the questionnaire (84%); mostly intensivists (n=124, [54%]). Body temperature was most frequently measured using a bladder probe (n=93, [43%]). A large proportion of respondents considered fever as a body temperature >38.3 degrees C (n=71, [33%]). The main thresholds for antipyretic therapy were 37.5 degrees C (n=74, [34%]) and 38.0 degrees C (n=86, [40%]); however, lower thresholds (37.0 to 37.5 degrees C) were targeted in cases of intracranial hypertension and cerebral ischemia. Among first-line methods to treat fever, ice packs were the most frequently utilized physical method (n=90, [47%]), external nonautomated system was the most frequent utilized device (n=49, [25%]), and paracetamol was the most frequently utilized drug (n=135, [70%]). Among second-line methods, intravenous infusion of cold fluids was the most frequently utilized physical method (n=68, [35%]), external computerized automated system was the most frequently utilized device (n=75, [39%]), and diclofenac was the most frequently utilized drug (n=62, [32%]). Protocols for fever control and shivering management were available to 83 (43%) and 54 (28%) of respondents, respectively. CONCLUSIONS: In this survey we identified substantial variability in fever definition and application of temperature management in acute brain injury patients. These findings may be helpful in promoting educational interventions and in designing future studies on this topic.

PMID- 30273203 TI - Unraveling the Cause of Anuria Post Kidney Transplantation by Renal Scintigraphy. AB - A dynamic renal scintigraphy is widely used after renal transplantation to evaluate transplant function and possible complications. We report the case of a 27-year-old man with persisting anuria after kidney transplantation. A renal scintigraphy using Tc-ethylenedicysteine followed by SPECT/CT of the abdomen was performed showing tracer accumulation in the colon without any activity in the bladder, as a result of ureter reimplantation onto the sigmoid instead of onto the previously reconstructed bladder. Renal scintigraphy identified the cause and localization of the urinary leak, which led to immediate surgical reimplantation of the ureter onto the augmented bladder with onset of diuresis. PMID- 30273204 TI - 68Ga-PSMA-11 PET/CT in Newly Diagnosed Prostate Adenocarcinoma. AB - INTRODUCTION: Prostate-specific membrane antigen (PSMA) ligand PET/CT is an emerging modality to detect the metastatic disease, especially in intermediate- and high-risk prostate cancer (PCa). In this study, we analyzed the contribution of Ga-PSMA-11 PET/CT in staging and therapy management of newly diagnosed PCa. MATERIALS AND METHODS: A total of 78 patients with biopsy-proven PCa who were referred for Ga-PSMA-11 PET/CT for primary staging were retrospectively analyzed. The patients were divided into risk groups according to the D'Amico risk stratification criteria. All of the patients had undergone pelvic MRI, and 65 patients had bone scintigraphy also. The findings of Ga-PSMA-11 PET/CT were compared with these conventional imaging (CI) methods for staging of the disease. The relations between SUVmax of the primary tumors and Gleason scores (GSs), prostate-specific antigen (PSA) levels, and metastatic extent of the disease were analyzed. RESULTS: Of 78 patients, 5 patients were in low-risk group, 18 patients were in intermediate-risk group, and 55 patients were in high-risk group. Metastatic disease was found in 40 (51.2%) of 78 patients in Ga-PSMA-11 PET/CT. Ten patients had regional lymph node metastases, and 30 patients had distant metastases. Ga-PSMA-11 PET/CT changed the staging in 44 (56.4%) of 78 patients compared with CI. There was significant difference between the SUVmax of the tumors with GSs of 6 and 7 compared with GSs of 8, 9, and 10 (P = 0.003). The SUVmax were significantly different between the patients with no metastasis (n = 38) and patients with regional lymph node metastases or distant metastases (n = 40; 16.1 +/- 10.9, 28.7 +/- 25.8, P = 0.003, respectively). There was significant difference between the SUVmax of patients with PSA level less than 10 ng/mL compared with patients with PSA level of 10 or greater and less than 20 ng/mL and PSA 20 ng/mL or greater (P = 0.009). A weak correlation between PSA and primary tumor SUVmax was also found (r = 0.21). CONCLUSIONS: Ga-PSMA-11 PET/CT is an important imaging modality for primary evaluation of newly diagnosed PCa changing the disease stage substantially. Also the SUVmax of the primary tumor has a relation with GS, metastatic extent of disease, and PSA levels defining the prognosis. PMID- 30273205 TI - Pretreatment Primary Tumor and Nodal SUVmax Values on 18F-FDG PET/CT Images Predict Prognosis in Patients With Salivary Gland Carcinoma. AB - PURPOSE: To assess whether primary tumor and nodal F-FDG uptake may predict prognosis in patients with salivary gland carcinoma. METHODS: We conducted a 2 center, retrospective study on 117 patients with salivary gland carcinoma who underwent F-FDG PET/CT before treatment and were subsequently treated with curative intent between 2004 and 2014. Pretreatment SUVmax of the primary tumor (SUVmax-T) and that of positive nodes (SUVmax-N) were analyzed in relation to clinical outcomes. RESULTS: Patients were followed up for a median of 61 months. The following 5-year rates were observed: locoregional control (LRC), 78%; distant metastasis-free survival (DMFS), 67%; progression-free survival (PFS), 62%; and overall survival (OS), 68%. A cutoff value of 7.0 maximized the prognostic impact of both SUVmax-T and SUVmax-N for PFS. Compared with patients with SUVmax-T and SUVmax-N values below the optimal cutoff, those with SUVmax-T and SUVmax-N of 7 or greater showed less favorable 5-year LRC (P < 0.001 and P < 0.001), DMFS (P < 0.001 and P < 0.001), PFS (P < 0.001 and P < 0.001), and OS (P < 0.001 and P < 0.001) rates. Both SUVmax-T of 7 or greater and SUVmax-N of 7 or greater were identified as independent predictors of LRC (P = 0.010 and 0.022), DMFS (P = 0.001 and P = 0.001), PFS (P < 0.001 and P = 0.007), and OS (P = 0.007 and P = 0.002) in multivariable analysis. We therefore devised a prognostic scoring system based on these 2 variables, which was found to be strongly associated with 5-year LRC (P < 0.001), DMFS (P < 0.001), PFS (P < 0.001), and OS (P < 0.001) rates. CONCLUSIONS: SUVmax of the primary tumor and SUVmax-N on pretreatment F-FDG PET/CT images may be a useful guide in predicting treatment outcomes, especially when combined in a prognostic scoring system. PMID- 30273206 TI - Increased Activity Due to Fractures Does Not Significantly Affect the Accuracy of 68Ga-DOTATATE PET/CT in the Detection of Culprit Tumor in the Evaluation of Tumor Induced Osteomalacia. AB - OBJECTIVE: Ga-DOTATATE PET/CT is currently the most common imaging modality in localizing culprit tumors, which can result in tumor-induced osteomalacia (TIO). Fracture, which is one of the most common consequences of the TIO, can also lead to increased Ga-DOTATATE activity and potentially affect the accuracy of Ga DOTATATE PET/CT imaging. The aim of this investigation is to evaluate whether the increased Ga-DOTATATE activity at the sites of the fracture will cause interpretation difficulty in the localizing the culprit tumor causing TIO. METHOD: The images of Ga-DOTATATE PET/CT scan from a total of 54 patients who had multiple foci of increased Ga-DOTATATE PET/CT on PET/CT were retrospectively analyzed. Not only was the intensity of the activity on PET but also the appearance of the activity on CT taken into consideration when the interpretation of the images occurred. The results from imaging analysis were compared with the clinical chart record. All patients had tentative clinical diagnosis of TIO. RESULTS: The causative tumors in 53 patients were eventually identified. In 1 patient, the causative tumor was not identified. Among the 53 patients with confirmed TIO, 52 tumors were accurately localized. CONCLUSIONS: Mild activity at the sites of fracture is not a major challenging factor in the interpretation of Ga-DOTATATE PET/CT in the evaluation of TIO when both intensity on PET and morphology on CT were assessed. PMID- 30273207 TI - Incidental Detection of Skeletal Metastases on 99mTc-DTPA Renography. AB - We present the case of a 53-year-old man with left hydroureteronephrosis who underwent Tc-DTPA renography for functional assessment of bilateral kidneys. Tc DTPA renography of the patient showed diffusely increased extrarenal Tc-DTPA uptake in the visualized lumbosacral vertebrae and in the pelvic bones, on the blood flow and functional phase of the renography, which was suggestive of disseminated skeletal disease. Subsequent MRI lumbosacral spine and F-FDG PET/CT revealed extensive skeletal metastases corresponding to the increased extrarenal Tc-DTPA uptake in the lumbosacral vertebrae and the pelvic bones from primary left lung mitotic lesion. PMID- 30273208 TI - 18F-FDG PET/CT in Isolated Primary Extraskeletal Osteosarcoma. AB - Extraskeletal osteosarcoma is a rare, high-grade soft tissue malignancy, accounting for approximately 1% of all soft tissue sarcomas. Despite the histologic resemblance to osteogenic osteosarcoma, it is considered as a distinct entity because of the differences in clinical behavior and response to treatment. Hence, imaging plays a vital role in establishing the nonskeletal origin of the tumor, differentiating it from osteogenic osteosarcoma. We present F-FDG PET/CT findings in a case of isolated primary extraskeletal osteosarcoma confirmed on histopathology.

AB - In 2 high-risk prostate cancer patients, PET scans revealed focally increased Ga prostate-specific membrane antigen uptake in the distal esophagus. Both patients had hiatus herniation on gastroscopy, and esophageal biopsies revealed acute and chronic inflammation in both patients and a benign hyperplastic polyp in one of the patients. Recently, reports have demonstrated that inflammation can cause false-positive findings on Ga-prostate-specific membrane antigen PET/CT, and these cases present this phenomenon in the esophagus as well.

PMID- 30273212 TI - Oral Care Protocols With Specialty Training Lead to Safe Oral Care Practices and Reduce Iatrogenic Bleeding in Extracorporeal Membrane Oxygenation Patients. AB - INTRODUCTION: Oral care, using either a mouth rinse, gel, toothbrush, or combination of them, together with aspiration of secretions, may reduce the risk of ventilator-acquired pneumonia in intubated patents. Oral care procedure in patients on venovenous extracorporeal membrane oxygenation (VV-ECMO) may cause bleeding due to the systemic anticoagulation required. PURPOSE: The aim of this study was to investigate the rate of bleeding episodes during oral care in patients supported by VV-ECMO. METHODS: A retrospective observational study was performed. All patients admitted to an Italian ECMO center during 2014 were included in the study. RESULTS: Data from 14 patients were analyzed. The median intensive care unit length of stay was 39.0 days (interquartile range, 27.3-83.3 days), and median days on VV-ECMO was 19.5 (10.3-46.0). There were 440 ECMO days, with 1320 oral care maneuvers. In 7 patients, bleeding episodes occurred: 2 with orotracheal intubation and 5 initially managed with orotracheal intubation, thereafter via Translaryngeal tracheostomy tube (according to Fantoni's technique). In 61 oral care procedures (4.6%), bleeding was detected during or after the maneuver, whereas the total numbers of days with at least 1 bleeding episode were 35 (8%).The presence or absence of bleeding during ECMO days was statistically significant for international normalized ratio (1.01 [0.95-1.11] vs 1.13 [1.03-1.25], P < .0001), platelets (163 000 [93 500-229 000] vs 61 000 [91 00-100 000], P < .0001), and mouth care score (6 [5-7] vs 8 [7-9], P < .001). CONCLUSION: Oral care can cause bleeding in patients on VV-ECMO. Implementation of protocols for daily oral care in patients on ECMO may reduce risks. As recommended by the literature, this category of patients should be treated in selected centers distinguished by a regular volume of ECMO activity and the presence of dedicated ECMO specialist nurses.

AB - Data collection and management are often neglected subjects of qualitative research. Qualitative data collection, management, and analysis are complex and challenging for researchers especially for early career and doctoral students. These processes involve anticipating for ethical issues and developing means and methods for collecting, recording, and storing data securely. Approaches to data analysis include organizing, reading, coding, and organizing themes, representing, and interpreting the data. The unanticipated issues in accomplishing these steps and corresponding solutions are presented. Recommendations for training and mentoring of novices in qualitative research are discussed. PMID- 30273216 TI - Impact of a Nurse Intervention to Improve Sleep Quality in Intensive Care Units: Results From a Randomized Controlled Trial. AB - BACKGROUND: Patients of adult intensive care units (ICUs) often suffer from a lack of sleep. Reducing anxiety by promoting adaptation to the ICU prior to admission may be an appropriate way to increase sleep quality. OBJECTIVE: The aim of this study was to evaluate the impact on sleep quality of a brief nurse intervention. METHODS: This was a pilot randomized controlled trial in Spain. Forty patients admitted in hospital for valve cardiac surgery were randomly allocated to (1) control group (n = 20), receiving usual care, and to (2) experimental group (EG, n = 20), receiving a nurse intervention the day before surgery and admission in the ICU. The intervention was based on Roy Adaptation Model. A trained nurse anticipated the stressful stimulus to patients in order to develop functional adaptive behaviors. A set of photographs and videos was used to illustrate the environment and assistance in the ICU. Sleep quality in the ICU was measured with the Richards-Campbell Sleep Questionnaire and usual sleep quality with the Pittsburgh Sleep Quality Index. RESULTS: After the intervention, sleep quality was lower in the EG compared with the control group (-4 points in Richards-Campbell Sleep Questionnaire, P = .69). Adjustment for main confounders led this reduction to -1.9 points (P = .87) among patients in EG. Stratified analyses shown a positive impact for people who usually slept well (+5.2 points, P = .77), but negative for those who had previous poor sleep quality (-20.0 points, P = .24). CONCLUSION: A nurse intervention prior to ICU admission did not increase patients' sleep quality. In addition, the intervention could have incremented anxiety over the patients who used to sleep poorly at their homes. PMID- 30273219 TI - Thank You, DCCN Peer Reviewers 2017-2018. PMID- 30273218 TI - Nurse-Initiated Mobilization Practices in 2 Community Intensive Care Units: A Pilot Study. AB - BACKGROUND: Critical-care nurses play a vital role in promoting safe early mobilization in intensive care unit (ICU) settings to reduce the risks associated with immobility in ICUs, including the risk of delirium, ICU-acquired weakness, and functional decline. OBJECTIVE: The purposes of this study were to describe nurse-led mobilization practices in 2 community hospital ICUs and to report differences and similarities between the 2 settings. METHODS: This was a cross sectional exploratory study of 18 nurses (ICU A: n = 12, ICU B: n = 6) and 124 patients (ICU A: n = 50, ICU B: n = 74). Patient-specific therapeutic intervention needs and nurse-initiated mobilization practices were tracked over a 1-month period. RESULTS: Differences in patient characteristics and nurse-led mobilization activities were observed between ICUs. After controlling for patient characteristics, we found statistically significant differences in nurse-led mobilization activities between the 2 units, suggesting that factors other than patient characteristics may explain differences in nurse-led mobilization practices. PMID- 30273220 TI - Celebrating "What Matters" for the Holidays. PMID- 30273221 TI - Aquatic Orthopaedic Injuries. AB - Extremity injuries sustained in aquatic environments require unique considerations compared with injuries sustained on land. Knowledge of these considerations is becoming more important as aquatic recreational activities increase in popularity. Aquatic injuries may occur through mechanical contact with a variety of different objects or surfaces, such as a recreational device or watercraft part, or may occur through contact with marine animals. Marine animal injuries can be further categorized into bites, stings, or blunt contact, as well as venomous or nonvenomous, distinctions that should be used to guide clinical management. Numerous instances of retained foreign bodies after marine animal stings exist, which can result in infection and prolonged envenomization; thus, radiographic examination should be routinely performed in aquatic sting injuries to prevent these harmful sequelae. Any aquatic injury resulting in an open wound has an increased risk for infection, and prophylactic antibiotics must be given with consideration for the unique microbiologic flora of the aquatic environment. PMID- 30273222 TI - Arthroscopic Management of Glenohumeral Arthritis: A Joint Preservation Approach. AB - Treatment of young, active patients with primary glenohumeral osteoarthritis (GHOA) is challenging because shoulder arthroplasty may not be ideal in this population. In the past two decades, joint-preserving arthroscopic management options for GHOA, including debridement, have been used to treat different pathologies related to GHOA to reduce pain, to improve function, and to delay or even avoid arthroplasty. Key aspects of comprehensively addressing GHOA arthroscopically include chondroplasty, synovectomy, loose body removal, humeral osteoplasty with excision of the goat's beard osteophyte, capsular release, subacromial and subcoracoid decompression, axillary nerve decompression, and biceps tenodesis. Although data are still emerging, clinical studies report that an arthroscopic approach to glenohumeral arthritis using these various procedures reduces pain, improves function, and improves clinical outcome scores in the short- to mid-term follow-up period. Additional high-level studies are warranted to evaluate long-term outcomes and durability following this procedure. PMID- 30273223 TI - Testing between the gunpowder fuse and the filling-hose analogy for mental curve tracing using electroencephalography: boom! AB - Curve tracing occurs when a line is followed covertly to accomplish a task, for example, to determine whether two landmarks are on the same line or not (could Highway 61 take Robert Johnson from New Orleans to St Louis?). Previous work suggests that attention either moves along the curve, momentarily activating local representations of the curve during this process, leaving little or no trace of this activation once attention has passed, or attention spreads along the curve, resulting in an activated state along the entire portion of the curve that was traced. We re-examined this issue using event-related potentials. Curves to be traced were presented briefly to encourage a rapid deployment of attention. The curves started on the vertical midline and passed into the left or right visual field and terminated either on the vertical midline or at a lateral position. We measured a posterior contralateral negativity (relative to the visual field of the traced curve) that offset more rapidly when the curve was traced back to the midline than when it remained lateral. The results suggest that attention travels along the curve like fire on a fuse, with activation returning to baseline once the flame has passed. PMID- 30273224 TI - The endoplasmic reticulum stress transducer old astrocyte specifically induced substance positively regulates glial scar formation in spinal cord injury. AB - To investigate the relationship between endoplasmic reticulum (ER) stress mediated by old astrocyte specifically induced substance (OASIS) and astrogliosis in spinal cord injury (SCI). SCI models were established using adult male mice deficient for OASIS and C57BL/6 (wild-type mice) mice. After SCI, recovery and astrogliosis were examined in the mice at specific time points using functional and histological methods. After SCI, functional recovery was better in the OASIS deficient mice than in the wild-type mice. OASIS deletion did not inhibit astrocyte migration but reduced the excessive accumulation of N-cadherin expressing reactive astrocytes that formed the glial scar around the injury site. In addition, OASIS deletion increased the number of serotonin-positive axons in spinal cord regions caudal to the injury site. These findings suggested that the OASIS-mediated ER stress response inhibits the repair of the injured spinal cord by promoting the development of N-cadherin-expressing reactive astrocytes that form glial scars following injury. OASIS deletion inhibited the development of N cadherin-positive reactive astrocytes that form glial scars and promoted axon growth and functional recovery after SCI. These results suggest that the ER stress response mediated by OASIS could be a new target in the treatment of SCI. PMID- 30273225 TI - Testis Involvement in Neuroblastoma: Report of 3 Cases in the Turkish Pediatric Oncology Group-Neuroblastoma Study and Review of the Literature. AB - BACKGROUND: Neuroblastoma (NB) is the most common extracranial solid tumor of childhood. Primary and secondary testicular involvement is extremely uncommon in neuroblastoma. PROCEDURE: All children with neuroblastoma treated with the Turkish Pediatric Oncology Group (TPOG)-Neuroblastoma (NB) Study and who had testis involvement either at diagnosis or at relapse were retrospectively evaluated. A review of all cases with neuroblastoma and testis involvement in the literature was done. RESULTS: There were 3 children with NB documented to have involvement of the testis, 2 at diagnosis, 1 at recurrence, within the 559 cases (0.5%) treated with the Turkish Pediatric Oncology Group (TPOG)-Neuroblastoma Protocol. All had advanced stage. Two were infants. A total of 57 cases of testicular or paratesticular neuroblastoma have been reported in children, and most cases represent metastases as in the 3 cases in our series. CONCLUSIONS: Neuroblastoma should be considered in the differential diagnosis of testicular mass and work-up for neuroblastoma should be done before orchiectomy. Scrotal ultrasonography should be used as the first diagnostic tool and abdominal ultrasonography shall be done additionally. Testis examination should be performed at diagnosis and regularly during follow-up for boys diagnosed with neuroblastoma. Testes may be sanctuary sites when neuroblastoma is metastatic, as is the case in leukemia. PMID- 30273226 TI - Short article: Frequency, pathophysiology, and clinical classification of intestinal failure type II and III at a tertiary referral center. AB - OBJECTIVE: Intestinal failure (IF) is a complex disease that is gaining significance and attention throughout the world. In Mexico, there are no available data on this condition. The aim of this study was to determine the frequency and characteristics of patients with IF type II and III hospitalized at a tertiary referral center in our country. PATIENTS AND METHODS: A cross sectional study was carried out from August 2016 to July 2017. Adult patients hospitalized in noncritical areas with a recent diagnosis of IF type II or III according to the European Society for Clinical Nutrition and Metabolism classification were included. Demographic, anthropometric, nutritional therapy, biochemical, and clinical characteristics were registered. Nutritional risk was determined by the Nutritional Risk Score 2002. RESULTS: During the study, 4144 patients were admitted to noncritical areas; 21 (5/1000) of these patients were included. The mean age of the patients was 51+/-18.8 years, and the mean BMI was 17.6+/-5.5 kg/m. Fifteen (71.5%) patients were diagnosed with IF type II and six (28.5%) with IF type III. The primary diagnosis was surgical complications in seven (33.3%) of the cases and the principal pathophysiological mechanism was short bowel syndrome in nine (42.8%) patients. The most frequent (37%) clinical classification was D2: more than 20 kcal/kg/day and 1001-2000 ml/day and parenteral nutrition and PN2: 1001-2000 ml/day (52.3%) based on the modified European Society for Clinical Nutrition and Metabolism clinical classification. CONCLUSION: In this study, a high frequency of IF was found; surgical complications and short bowel syndrome were the main mechanisms involved, and D2 was the most frequent clinical category. PMID- 30273227 TI - Dysregulation of the Inflammatory Mediators in the Multifidus Muscle After Spontaneous Intervertebral Disc Degeneration SPARC-null Mice is Ameliorated by Physical Activity. AB - STUDY DESIGN: A longitudinal case-control animal model. OBJECTIVE: The aim of this study was to investigate the inflammatory pathways active in the multifidus muscle after spontaneous intervertebral disc degeneration (IDD), and whether these IDD-related muscle changes can be ameliorated by exercise. SUMMARY OF BACKGROUND DATA: A pro-inflammatory response is present in the multifidus muscle after an intervertebral disc lesion and has been proposed to drive the structural alterations present during low back pain. However, it is not known whether spontaneous IDD produces an inflammatory response. Furthermore, exercise/physical activity produces a strong anti-inflammatory response, but its effectiveness in ameliorating inflammation in the multifidus is unknown. We assessed the inflammatory profile of the multifidus and the effectiveness of physical activity as a treatment using an animal model of spontaneous model of IDD. METHODS: Wild type and SPARC null mice that were sedentary or housed with a running wheel were used in this study. Multifidus muscle segments were harvested from L2-L6 from the mice at 9 months of age after they had undergone a magnetic resonance imaging (MRI) scan to determine levels with IDD. The inflammatory profile of the multifidus was examined using quantitative polymerase chain reaction (PCR) assays. RESULTS: Spontaneous IDD in the SPARC-null mice caused a dysregulation of interleukin (IL)-1beta, IL6, transforming growth factor-beta (TGFbeta1), and adiponectin expression. More specifically, the proximity and degree of IDD was related to levels of IL-1beta expression. Physical activity reduced the pro inflammatory response to IDD in the multifidus. IL-1beta, tumor necrosis factor (TNF), IL-10, adiponectin, and leptin levels were lower in the physically active group. CONCLUSION: These results reveal that spontaneous IDD causes dysregulation of the inflammatory pathways active in the multifidus muscle. These alterations were related to the severity of IDD and were prevented by physical activity. LEVEL OF EVIDENCE: N/A.

PMID- 30273229 TI - Persistent Nociception Facilitates the Extinction of Morphine-Induced Conditioned Place Preference. AB - BACKGROUND: As opioid abuse and addiction have developed into a major national health crisis, prescription of opioids for pain management has become more controversial. However, opioids do help some patients by providing pain relief and improving the quality of life. To better understand the addictive properties of opioids under chronic pain conditions, we used a conditioned place preference (CPP) paradigm to examine the rewarding properties of morphine in rats with persistent nociception. METHODS: Spared nerve injury (SNI) model was used to induce persistent nociception in rats. Nociceptive behavior was assessed by von Frey test. CPP test was used to examine the rewarding properties of morphine. RESULTS: Our findings are as follows: (1) SNI rats did not show a difference compared with sham rats in magnitude of morphine-induced CPP 1 day after last morphine injection (2-way analysis of variance; for SNI versus sham, F[1,42] = 0.014, P = .91; and 95% confidence intervals for difference of means, -5.9 [-58 to 46], 0.76 [-51 to 53], and 0.90 [-51 to 53] for 2.5, 5, and 10 mg/kg, respectively); (2) increasing morphine dosage (2.5, 5, and 10 mg/kg) did not further increase the magnitude of CPP in both sham and SNI rats (for dosage: F[2,42] = 0.94, P = .40); and (3) morphine-induced CPP persisted in sham rats but extinguished in SNI rats when tested at 8 days after last morphine injection (for sham versus SNI: Bonferroni correction, P < .006 for both 5 and 10 mg/kg doses; and 95% confidence intervals for difference of means, 80.3 [19.7-141] and 87.0 [26.3-148] for 5 and 10 mg/kg, respectively). CONCLUSIONS: Our data provide new evidence supporting the notion that the brain's reward circuitry changes in the context of persistent pain. This observational study suggests that future investigation into the neurobiology of opioid reward requires consideration of the circumstances in which opioid analgesics are administered. PMID- 30273230 TI - Grade 3 Echocardiographic Diastolic Dysfunction Is Associated With Increased Risk of Major Adverse Cardiovascular Events After Surgery: A Retrospective Cohort Study. AB - BACKGROUND: Diastolic dysfunction is common and may increase the risk of cardiovascular complications. This study investigated the hypothesis that, in patients with isolated left ventricular diastolic dysfunction, higher grade diastolic dysfunction was associated with greater risk of major adverse cardiovascular events (MACEs) after surgery. METHODS: This was a retrospective cohort study. Data of adult patients with isolated echocardiographic diastolic dysfunction (ejection fraction, >=50%) who underwent noncardiac surgery from January 1, 2015 to December 31, 2015 were collected. The primary end point was the occurrence of postoperative MACEs during hospital stay, which included acute myocardial infarction, congestive heart failure, stroke, nonfatal cardiac arrest, and cardiac death. The association between the grade of diastolic dysfunction and the occurrence of MACEs was assessed with a multivariable logistic model. RESULTS: A total of 2976 patients were included in the final analysis. Of these, 297 (10.0%) developed MACEs after surgery. After correction for confounding factors, grade 3 diastolic dysfunction was associated with higher risk of postoperative MACEs (odds ratio, 1.71; 95% confidence interval, 1.28-2.27; P < .001) when compared with grades 1 and 2. Patients with grade 3 diastolic dysfunction developed more non-MACE complications when compared with grades 1 and 2 (uncorrected odds ratio, 1.44; 95% confidence interval, 1.07-1.95; P = .017). CONCLUSIONS: In patients with isolated diastolic dysfunction undergoing noncardiac surgery, 10.0% develop MACEs during hospital stay after surgery; grade 3 diastolic dysfunction is associated with greater risk of MACEs.This is an open access article distributed under the terms of the Creative Commons Attribution Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30273231 TI - Clock Drawing Performance Slows for Older Adults After Total Knee Replacement Surgery. AB - BACKGROUND: Clock drawing is a neurocognitive screening tool used in preoperative settings. This study examined hypothesized changes in clock drawing to command and copy test conditions 3 weeks and 3 months after total knee arthroplasty (TKA) with general anesthesia. METHODS: Participants included 67 surgery and 66 nonsurgery individuals >60 years who completed the digital clock drawing test before TKA (or a pseudosurgery date), and 3 weeks and 3 months postsurgery. Generalized linear mixed models assessed digital clock drawing test latency (ie, total time to completion, seconds between digit placement) and graphomotor output (ie, total number of strokes, clock size). Reliable change analyses examined the percent of participants showing change beyond differences found in nonsurgery peers. RESULTS: After adjusting for age, education, and baseline cognition, both digital clock drawing test latency measures were significantly different for surgery and nonsurgery groups, where the surgery group performed slower on both command and copy test conditions. Reliable change analyses 3 weeks after surgery found that total time to completion was slower among 25% of command and 21% of copy constructions in the surgery group. At 3 months, 18% of surgery participants were slower than nonsurgery peers. Neither graphomotor measure significantly changed over time. CONCLUSIONS: Clock drawing construction slowed for nearly one quarter of patients after TKA surgery, whereas nonsurgery peers showed the expected practice effect, ie, speed increased from baseline to follow-up time points. Future research should investigate the neurobiological basis for these changes after TKA. PMID- 30273232 TI - Pilot Survey of Female Anesthesiologists' Childbearing and Parental Leave Experiences. AB - While the literature regarding physicians' childbearing experiences is growing, there are no studies documenting those of anesthesiologists. We surveyed a convenience sample of 72 female anesthesiologists to obtain pilot data. Sixty-six women completed the survey (91.7% response rate), reporting 113 total births from before 1990 to present. Of all birth experiences, proportions of respondents reporting parental leave, lactation facilities, and lactation duration as adequate were 52.3%, 45.2%, and 58.3%, respectively. Most mothers (51.8%) gave birth to their first child while they were trainees. The majority (94.9%) favored an official statement supporting parental leave. These results may serve as groundwork for larger studies. PMID- 30273233 TI - Cutaneous adverse events of anti-programmed death 1 antibodies combined with anti cytotoxic T-lymphocyte-associated protein 4 therapy use in patients with metastatic melanoma. AB - To date, cutaneous toxicities of combination therapies of anti-programmed death-1 (anti-PD1) and ipilimumab are poorly described. Understanding cutaneous presentations will aid clinicians with early diagnoses and treatments. We aim to describe and compare the cutaneous toxicities between the combination therapies and anti-PD1 monotherapy. This is a cohort study comparing previously published data on 82 patients with metastatic melanoma on anti-PD1 monotherapy, with a new group of 25 patients with metastatic melanoma receiving combined ipilimumab and pembrolizumab between January 2015 to February 2016. A single institution, internal referrals were received from medical oncology teams from May 2012 to February 2015 for the anti-PD1 monotherapy group and from January 2015 to February 2016 for combination group. All patients who were treated with either anti-PD1 therapy or combination therapies during the timeframe within the institution were included in the study. Kaplan-Meier curves were used to illustrate the time taken to develop cutaneous toxicities in the monotherapy and combination groups. Of the 25 patients, 88% developed new cutaneous lesions since the treatment. Immune-related lesions; lichenoid reaction (64%) and vitiligo (28%) were the most frequent. The incidence of lichenoid reaction increased rapidly in the early phase of treatment. Approximately one-third developed their first lichenoid reaction within 12 days of commencing treatment in combination group compared to 14 months in the anti-PD1 monotherapy. The rate of incidence of vitiligo was comparable in both groups. There was no statistical significance in the development of cutaneous toxicities and the treatment response between the two groups. The time taken to develop immune-related cutaneous toxicities was shorter for those on combination therapy versus anti-PD1 monotherapy. PMID- 30273234 TI - A practical approach to predict expansion of evidence networks: a case study in treatment-naive advanced melanoma. AB - Network meta-analysis (NMA) is a statistical method used to produce comparable estimates of efficacy across a range of treatments that may not be compared directly within any single trial. NMA feasibility is determined by the comparability of the data and presence of a connected network. In rapidly evolving treatment landscapes, evidence networks can change substantially in a short period of time. We investigate methods to determine the optimum time to conduct or update a NMA based on anticipated available evidence. We report the results of a systematic review conducted in treatment-naive advanced melanoma and compare networks of evidence available at retrospective, current, and prospective time points. For included publications, we compared the primary completion date of trials from clinical trials registries (CTRs) with the date of their first available publication to provide an estimate of publication lag. Using CTRs we were able to produce anticipated networks for future time points based on projected study completion dates and average publication lags which illustrated expansion and strengthening of the initial network. We found that over a snapshot of periods between 2015 and 2018, evidence networks in melanoma changed substantively, adding new comparators and increasing network connectedness. Searching CTRs for ongoing trials demonstrates it is possible to anticipate future networks at a certain time point. Armed with this information, sensible decisions can be made over when best to conduct or update a NMA. Incorporating new and upcoming interventions in a NMA enables presentation of a complete, up-to date and evolving picture of the evidence. PMID- 30273236 TI - The effect of the opioid epidemic on donation after cardiac death transplantation outcomes. AB - BACKGROUND: The opioid abuse epidemic and the deaths of otherwise healthy individuals due to drug overdose in the United States has major implications for transplantation. The current extent and safety of utilization of liver and kidney grafts from donation after cardiac death (DCD) donors who died in the context of opioid overdose is unknown. METHODS: Using national data from 2006 to 2016, we estimated the cumulative incidence of graft failure for recipients of DCD grafts, comparing the risk amongst recipients of organs from donors who died of anoxic drug overdose and recipients of organs from donors who died of other causes. RESULTS: One hundred and seventy-nine (6.2%) of 2908 liver graft recipients and 944 (6.1%) of 15 520 kidney graft recipients received grafts from donors who died of anoxic drug overdose. Grafts from anoxic drug overdose donors were less frequently utilized compared to other DCD grafts (liver: 25.9% vs. 29.6%, 95% CI for difference, -6.7 to -0.7%; kidney: 81.0% vs. 84.7%; CI for difference, -7.3 to -0.1%). However, the risk of graft failure at 5-years was similar for recipients of anoxic drug overdose donor grafts and recipients of other grafts (liver risk difference: 1.8% [95% CI, -7.8 to 11.8%], kidney risk difference: 1.5% [95% CI, -5.4 to 3.1%]). CONCLUSIONS: In the context of the current opioid epidemic, utilization of anoxic drug overdose DCD donor grafts does not increase the risk of graft failure and may help to address waitlist demands. PMID- 30273238 TI - Neuroinfectious Disease in Isolation. PMID- 30273235 TI - Kaposi sarcoma in HIV-positive solid organ transplant recipients: A French multicentric national study and literature review. AB - BACKGROUND: Kaposi sarcoma is a vascular tumor related to herpesvirus-8 and is promoted by immunosuppression. For the last 15 years, HIV patients have had access to organ transplantation. The dual immunosuppression of HIV and immunosuppressive treatments might increase the risk and severity of Kaposi sarcoma. METHODS: We conducted a multicentric retrospective study by collecting cases from French databases and society members of transplanted patients, among which 7 HIV-infected patients who subsequently developed Kaposi sarcoma were included. RESULTS: In the CRISTAL database (114 511 patients) and the DIVAT database (19 077 patients), the prevalence of Kaposi sarcoma was 0.18% and 0.46%, respectively, in transplanted patients; these values compare with 0.66% and 0.50%, respectively, in transplanted patients with HIV. The median time from HIV infection to Kaposi sarcoma was 20 years. Kaposi sarcoma occurred during the first year after transplantation in most cases, while HIV viral load was undetectable. Only 2 patients had visceral involvement. Five patients were treated with conversion of calcineurin inhibitor to mTOR inhibitor, and 5 patients were managed by decreasing immunosuppressive therapies. At 1 year, 4 patients had a complete response, and 3 had a partial response. CONCLUSIONS: In our study, Kaposi sarcoma in transplanted patients with HIV did not show any aggressive features and was treated with the usual posttransplant Kaposi sarcoma management protocol. PMID- 30273239 TI - Acute Bacterial Meningitis. AB - PURPOSE OF REVIEW: While acute bacterial meningitis is becoming less common in developed countries because of the widespread use of vaccines against Streptococcus pneumoniae, Neisseria meningitides, and Haemophilus influenzae, bacterial meningitis still occurs worldwide, with peak incidence in young children and the elderly. Bacterial meningitis is usually lethal unless appropriate antibiotics that cross the blood-brain barrier are given. Clinical suspicion of bacterial meningitis begins when patients present with the abrupt onset of fever, headache, and meningismus. RECENT FINDINGS: New technologies are being developed for more rapid identification of the bacterial species causing meningitis. When appropriate, administration of adjunctive dexamethasone with the antibiotics often lessens neurologic sequelae in survivors, which may include aphasia, ataxia, paresis, hearing loss, and cognitive impairment. SUMMARY: Confirmation of the diagnosis of bacterial meningitis comes mainly from examination and culture of CSF obtained from a lumbar puncture. Typically, the CSF shows an elevated neutrophil count, elevated protein, depressed glucose, positive Gram stain, and growth of the bacteria on appropriate culture media. Antibiotic sensitivities of the bacteria determine the appropriate antibiotics, although an educated guess of the best antibiotics to be given promptly must be made until the antibiotic sensitivities return, usually in a few days. PMID- 30273240 TI - Viral Meningitis and Encephalitis. AB - PURPOSE OF REVIEW: This article discusses meningitis and encephalitis infections caused by viruses, excluding herpes family and human immunodeficiency virus (HIV). RECENT FINDINGS: The viral infections of the nervous system detailed in this article have no specific treatment other than supportive care. However, many of the viruses discussed are highly preventable by vaccination, proper skin protection against transmitting vectors, and postexposure prophylaxis. SUMMARY: While meningitis and encephalitis caused by viruses may have some clinical overlap, the management and outcomes can be highly disparate, making distinction between the two imperative. Furthermore, despite their relative rarity in terms of clinical disease, many of the viral infections discussed herein are highly preventable. Given the morbidity and mortality attached to such infections, provider and patient education are the best approach available to prevent these potentially devastating illnesses. PMID- 30273241 TI - Chronic Meningitis. AB - PURPOSE OF REVIEW: This article describes the clinical presentation, diagnostic approach (including the use of novel diagnostic platforms), and treatment of select infectious and noninfectious etiologies of chronic meningitis. RECENT FINDINGS: Identification of the etiology of chronic meningitis remains challenging, with no cause identified in at least one-third of cases. Often, several serologic, CSF, and neuroimaging studies are indicated, although novel diagnostic platforms including metagenomic deep sequencing may hold promise for identifying organisms. Infectious etiologies are more common in those at risk for disseminated disease, specifically those who are immunocompromised because of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), transplantation, or immunosuppressant medications. An important step in identifying the etiology of chronic meningitis is assembling a multidisciplinary team of individuals, including those with specialized expertise in ophthalmology, dermatology, rheumatology, and infectious diseases, to provide guidance regarding diagnostic procedures. SUMMARY: Chronic meningitis is defined as inflammation involving the meninges that lasts at least 4 weeks and is associated with a CSF pleocytosis. Chronic meningitis has numerous possible infectious and noninfectious etiologies, making it challenging to definitively diagnose patients. Therefore, a multifaceted approach that combines history, physical examination, neuroimaging, and laboratory analysis, including novel diagnostic platforms, is needed. This article focuses on key aspects of the evaluation of and approach to patients with chronic meningitis. Specific infectious etiologies and differential diagnoses of subacute and chronic meningitis, including noninfectious etiologies, are addressed. PMID- 30273242 TI - Brain and Spinal Epidural Abscess. AB - PURPOSE OF REVIEW: Brain abscesses and spinal epidural abscesses are serious, potentially life-threatening infections of the central nervous system. This article outlines the clinical presentation, evaluation, and management of brain abscesses and spinal epidural abscesses, with a specific focus on bacterial infections. RECENT FINDINGS: The overall incidence of brain abscesses has declined, in part because of fewer brain abscesses associated with otogenic infections. However, emerging patient populations at high risk for brain abscess include those with a history of penetrating head trauma, neurosurgery, or immunodeficiency. Improved mortality rates for brain abscess are attributable to modern diagnostic imaging, stereotactic-guided aspiration, and newer antimicrobials that readily penetrate into the central nervous system and abscesses. Brain MRI is more sensitive than CT for brain abscess, particularly in the early stages, but CT remains more widely available and can adequately identify potential abscesses and confirm response to treatment. With the advent of minimally invasive neurosurgical techniques, surgical excision is often employed only for posterior fossa, multiloculated, or superficial well circumscribed abscesses. In select clinical scenarios, conservative medical management may be a safe alternative to a combined surgical and medical approach. Unlike brain abscess, the incidence of spinal epidural abscess is on the rise and has been attributed to higher prevalence of predisposing factors, including spinal procedures and instrumentation. SUMMARY: Successful diagnosis and management of brain abscess and spinal epidural abscess requires a collaborative approach among neurologists, neurosurgeons, radiologists, and infectious disease physicians. The foundation of management of brain abscess includes surgical intervention for diagnostic purposes if a pathogen has not been identified or for decompression of larger abscesses or those with mass effect and significant surrounding edema; appropriate dosing and adequate duration of an antimicrobial regimen tailored to the presumptive source of infection and available culture data, and eradication of the primary source of infection. For spinal epidural abscesses, neurologic status at the time of presentation is directly related to outcomes, underscoring the importance of prompt recognition and intervention. PMID- 30273243 TI - Herpesvirus Infections of the Nervous System. AB - PURPOSE OF REVIEW: This article reviews the spectrum of neurologic disease associated with human herpesvirus infections. RECENT FINDINGS: As more patients are becoming therapeutically immunosuppressed, human herpesvirus infections are increasingly common. Historically, infections with human herpesviruses were described as temporal lobe encephalitis caused by herpes simplex virus type 1 or type 2. More recently, however, additional pathogens, such as varicella-zoster virus, Epstein-Barr virus, cytomegalovirus, and human herpesvirus 6 have been identified to cause serious neurologic infections. As literature emerges, clinical presentations of herpesvirus infections have taken on many new forms, becoming heterogeneous and involving nearly every location along the neuraxis. Advanced diagnostic methods are now available for each specific pathogen in the herpesvirus family. As data emerge on viral resistance to conventional therapies, newer antiviral medications must be considered. SUMMARY: Infections from the herpesvirus family can have devastating neurologic outcomes without prompt and appropriate treatment. Clinical recognition of symptoms and appropriate advanced testing are necessary to correctly identify the infectious etiology. Knowledge of secondary neurologic complications of disease is equally important to prevent additional morbidity and mortality. This article discusses infections of the central and peripheral nervous systems caused by herpes simplex virus type 1 and type 2, varicella-zoster virus, Epstein-Barr virus, cytomegalovirus, and human herpesvirus 6. The pathophysiology, epidemiology, clinical presentations of disease, diagnostic investigations, imaging characteristics, and treatment for each infectious etiology are discussed in detail. PMID- 30273244 TI - Central Nervous System Infections Complicating Immunosuppression and Transplantation. AB - PURPOSE OF REVIEW: This article reviews infections associated with cancer treatments and immunosuppressive/immunomodulatory therapies used in both neoplastic and non-neoplastic conditions, including hematopoietic cell transplantation and solid organ transplantation. It provides a clinical approach to the most commonly affected patient groups based on clinicoanatomic presentation and disease-specific risks resulting from immune deficits and drugs received. RECENT FINDINGS: The clinical presentations, associated neuroimaging findings, and CSF abnormalities of patients with central nervous system infections who are immunocompromised may differ from those of patients with central nervous system infections who are immunocompetent and may be confused with noninfectious processes. Triggering of brain autoimmunity with emergence of neurotropic antibodies has emerged as a recognized parainfectious complication. New unbiased metagenomic assays to identify obscure pathogens help clinicians navigate the increasing range of conditions affecting the growing population of patients with altered immunity. SUMMARY: Despite evidence-based prophylactic regimens and organism-specific antimicrobials, central nervous system infections continue to cause significant morbidity and mortality in an increasing range of patients who are immunocompromised by their conditions and therapies. Multiple new drugs put patients at risk for progressive multifocal leukoencephalopathy, which has numerous imaging and clinical manifestations; patients at risk include those with multiple sclerosis, for whom infection risk is becoming one of the most important factors in therapeutic decision making. Efficient, early diagnosis is essential to improve outcomes in these often-devastating diseases. PMID- 30273245 TI - Neurologic Complications of Human Immunodeficiency Virus Infection. AB - PURPOSE OF REVIEW: Widespread use of antiretroviral therapy (ART) has led to near normal life expectancy in people with human immunodeficiency virus (HIV) infection. However, neurologic complications of HIV remain common; can affect any part of the neuraxis; and are due to direct effects of the virus, immunosuppression because of untreated HIV infection, aberrant immune responses in the setting of ART initiation, and ART toxicities. RECENT FINDINGS: HIV associated neurocognitive disorder (HAND) remains one of the most common neurologic complications of HIV encountered today, but milder forms predominate in people on ART. No specific treatments for HAND exist, but small trials and epidemiologic evidence suggest paroxetine, intranasal insulin, and maraviroc may have utility in its treatment; further trials of these agents are ongoing. Widespread ART use has decreased the incidence of central nervous system opportunistic infections, but prognosis often remains poor in those who develop opportunistic infections. High-titer positive serum cryptococcal antigen is strongly predictive of cryptococcal meningitis and provides a tool to enhance diagnosis in areas with limited resources. HIV is an independent risk factor for stroke, and accelerated aging associated with HIV infection results in neurologic diseases of older age occurring at much younger ages in individuals infected with HIV. Ongoing HIV replication in the CSF despite peripheral virologic suppression may contribute to the development of HAND and may not improve despite adjusting the ART regimen to increase central nervous system penetrance. SUMMARY: Neurologists are likely to encounter patients infected with HIV in clinical practice. This article reviews the presentation, diagnosis, and management of the most common neurologic conditions associated with HIV infection and ART. PMID- 30273246 TI - Tuberculosis of the Central Nervous System. AB - PURPOSE OF REVIEW: This article details the epidemiology and clinical manifestations of central nervous system (CNS) tuberculosis (TB), provides guidance for diagnostic imaging and CSF testing, and recommends treatment strategies for tuberculous meningitis and other forms of CNS TB, illustrating key aspects of diagnosis and management with case presentations. RECENT FINDINGS: Although improvements in our understanding of the pathogenesis and management of CNS TB have occurred over the past 50 years, the emergence of multidrug-resistant and extensively drug-resistant TB, the advent of acquired immunodeficiency syndrome (AIDS), and the subsequent availability of highly active antiretroviral therapy that can produce the immune reconstitution inflammatory syndrome have complicated the diagnosis and treatment of CNS TB. Advances in diagnostic assays promise to increase the speed of diagnosis as well as the percentage of people with a confirmed rather than a presumptive diagnosis. Advances in precision medicine have identified polymorphisms in the LTA4H gene that influence the risk for inflammation in patients with tuberculous meningitis. SUMMARY: CNS TB continues to be a major cause of morbidity and mortality, with the majority of people affected living in low-income and middle-income countries. Newer diagnostic assays promise to increase the speed of diagnosis and improve appropriate selection of antituberculous therapy and anti-inflammatory medications. Despite these advances, CNS TB remains difficult to diagnose, and clinicians should have a low threshold for initiating empiric therapy in patients with presumptive infection. PMID- 30273247 TI - Neuroborreliosis and Neurosyphilis. AB - PURPOSE OF REVIEW: This article presents an overview of the current diagnosis and management of two spirochetal infections of the nervous system, neuroborreliosis (Lyme disease) and neurosyphilis, focusing on similarities and differences. Although neuroborreliosis was first identified almost a century ago, much confusion remains about how to accurately diagnose this quite treatable nervous system infection. Well-established diagnostic tools and therapeutic regimens exist for neurosyphilis, which has been well-known for centuries. RECENT FINDINGS: Serologic testing targeting the C6 antigen may simplify diagnostic testing in neuroborreliosis while improving accuracy. Historically, screening for syphilis has used a reaginic test followed by a treponeme-specific assay; alternative approaches, including use of well-defined recombinant antigens, may improve sensitivity without sacrificing specificity. In neuroborreliosis, measurement of the chemokine CXCL13 in CSF may provide a useful marker of disease activity in the central nervous system. SUMMARY: Lyme disease causes meningitis, cranial neuritis, radiculitis, and mononeuropathy multiplex. Cognitive symptoms, occurring either during (encephalopathy) or after infection (posttreatment Lyme disease syndrome) are rarely, if ever, due to central nervous system infection. Posttreatment Lyme disease syndrome is not antibiotic responsive. Syphilis causes meningitis, cranial neuritis, chronic meningovascular syphilis, tabes dorsalis, and parenchymal neurosyphilis. The organism remains highly sensitive to penicillin, but residua of chronic infection may be irreversible. PMID- 30273248 TI - Tetanus, Botulism, and Diphtheria. AB - PURPOSE OF REVIEW: This article reviews the pathophysiology, epidemiology, clinical manifestations, diagnosis, and treatment of tetanus, botulism, and diphtheric neuropathy. RECENT FINDINGS: Tetanus is most common in lower-income settings, but rare cases are seen in higher-income settings because of the inadequate maintenance of vaccination status. Foodborne botulism remains rare, but botulism can also be caused by IV drug use (wound botulism) and medical use of botulinum toxin (iatrogenic botulism); botulinum toxin has also been considered a potential agent of bioterrorism. Diphtheric neuropathy is rare but has been seen in recent epidemics in the former Soviet Union, and vaccination status is inadequate in a significant proportion of older individuals, creating the potential for subsequent epidemics. SUMMARY: Tetanus, botulism, and diphtheric neuropathy are rare in higher-resource settings where most neurologists practice; however, familiarity with the unique clinical manifestations of and laboratory evaluation for these disorders is essential for the rapid diagnosis and treatment of patients with these conditions. PMID- 30273249 TI - Helminthic Infections of the Central Nervous System. AB - PURPOSE OF REVIEW: This article discusses select helminthic parasitic infections that may affect the central nervous system and reviews the epidemiology, neurologic presentation, recommended diagnostic testing, and treatment approach to these infections. RECENT FINDINGS: Emigration from and travel to areas endemic for helminthic infections that affect the nervous system has led to increased incidence of parasitic neurologic disease in developed countries, necessitating that neurologists be familiar with the diagnostic and therapeutic approach to these diseases. Evidence is emerging on the optimal treatment for neurocysticercosis, which varies based on the form of the disease in the nervous system. SUMMARY: Parenchymal neurocysticercosis is a leading cause of acquired epilepsy worldwide, and extraparenchymal neurocysticercosis is responsible for many cases of hydrocephalus. Recognition of the different stages and locations of neurocysticercosis is essential for proper management. Similarly, schistosomiasis constitutes a major cause of myelopathy in endemic areas and requires prompt diagnosis and treatment to avoid permanent deficits. PMID- 30273250 TI - Zika Virus and Other Emerging Arboviral Central Nervous System Infections. AB - PURPOSE OF REVIEW: In recent years, we have observed the emergence and reemergence of a number of arthropod-borne viruses (arboviruses). Zika virus is the most recent addition to this group, first causing sporadic cases of uncomplicated febrile illness followed by sizeable outbreaks in the Pacific. However, the epidemiology and clinical features of Zika virus infection have changed rapidly and dramatically; it is now recognized as causing Guillain-Barre syndrome (GBS) in children and adults and congenital abnormalities in infected fetuses. This article reviews the epidemiology, clinical features, and diagnosis of Zika virus-associated neurologic illness and briefly reviews features of West Nile virus and Japanese encephalitis virus. RECENT FINDINGS: Zika virus has emerged as a significant human pathogen in recent years. In 2015, it began to cause large outbreaks of febrile rash illness in South America and the Caribbean. During these large Zika virus outbreaks, a significant increase in the incidence of GBS was also observed in multiple countries/territories. Zika virus-associated GBS has several unique features, including a relatively short interval between febrile illness and GBS onset, an unusually high incidence among older people, and prominent cranial nerve abnormalities. Congenital Zika syndrome includes a myriad of abnormalities, including microcephaly, lissencephaly, hydrocephalus, arthrogryposis, and parenchymal calcifications. Currently, no treatment has been identified for Zika virus, although work on vaccines is under way. SUMMARY: Arboviruses continue to surprise us with unexpected emergence in various locations, the nature of clinical illness, and outcomes. Zika virus presents a classic example of this type of emergence. Ongoing surveillance will be needed to evaluate the long-term pattern of Zika virus and related arboviruses.

PMID- 30273251 TI - Legal and Ethical Considerations of Disclosing Human Immunodeficiency Virus Seropositivity to a Surrogate Decision Maker. AB - Ethical and legal issues arise when a patient who is human immunodeficiency virus (HIV) positive lacks decision-making capacity and the HIV status must be disclosed to a surrogate decision maker to allow for informed medical decision making. This article discusses the special exceptions to confidentiality built into the Health Insurance Portability and Accountability Act privacy protections, the limitations on claims of common-law marriage, and public health laws that often require informing individuals who are either sex partners or needle-sharing partners of newly diagnosed HIV-infected individuals that they have been exposed to HIV infection. PMID- 30273256 TI - Is the National Institutes on Alcohol and Alcoholism Screening Guide Useful for Identifying Adolescents at Risk for Later Cigarette Smoking? A Prospective Study in Primary Care Clinics. AB - OBJECTIVES: This paper evaluated whether a 2-item assessment of alcohol use risk, developed by the National Institute on Alcohol Abuse and Alcoholism (NIAAA SG), prospectively predicted smoking status among a sample of adolescents visiting their primary care physician. METHODS: We analyzed a sample of 651 adolescents (57.80% female; 56.53% Hispanic, 22.73% African American, 14.44% White, 6.30% other) who completed the NIAAA SG at a baseline appointment and were assessed for future smoking risk. We obtained prospective data on smoking status using data from the 6-month post-baseline follow-up assessment. RESULTS: Logistic regression analyses revealed that adolescents who were identified as at risk by the NIAAA SG were more likely to report smoking within 6 months. However, the association between the NIAAA SG and future smoking status became non-significant after controlling for future smoking risk measured at baseline. CONCLUSIONS: Questions that ask about past smoking and future smoking intentions are best used to screen adolescents in primary care for smoking risk. PMID- 30273257 TI - Psychosocial Adjustment and Quality of Life in Patients With Peripartum Cardiomyopathy. AB - BACKGROUND: Psychological distress can adversely affect heart failure prognosis, yet the immediate and ongoing challenges faced by women diagnosed with peripartum cardiomyopathy (PPCM) are not well studied. OBJECTIVE: We examined psychological distress and quality of life in a large, national sample of patients with PPCM and evaluated whether these characteristics differ among newly diagnosed (0-1 year), short-term (2-4 years), and long-term (5-10 years) survivors. METHODS: One hundred forty-nine patients with PPCM (mean age, 33.9 +/- 5.0 years) recruited from a web-based registry completed questionnaires about generalized anxiety (Generalized Anxiety Disorder-7), cardiac anxiety (Cardiac Anxiety Questionnaire [CAQ]), health status (Medical Outcomes Study Short-Form 12 [SF-12] Health Survey), and PPCM-specific quality-of-life concerns. Group differences were evaluated using multivariate statistics with adjustments for disease severity and psychiatric history. RESULTS: Generalized anxiety symptoms higher than the clinical cutoff were reported by 53% of patients with PPCM. Mean scores on the CAQ (1.9 +/- 0.7) and CAQ subscale scores (cardiac-specific fear [2.1 +/- 0.8], avoidance [1.7 +/- 0.9], and heart-focused attention [1.6 +/- 0.8]) were elevated in the overall sample. Psychological symptoms and quality-of-life concerns were generally similar across patients except for cardiac avoidance, which was significantly higher in newly diagnosed women after adjustments for disease severity (P = .05) and psychiatric history (P = .01). Peripartum cardiomyopathy specific quality-of-life concerns were also prevalent; however, group differences were nonsignificant (P = .07). CONCLUSIONS: Generalized anxiety, cardiac anxiety, and quality-of-life concerns are prevalent among patients with PPCM at all stages of recovery. Psychological issues may be an underrecognized aspect of women's recovery from PPCM. PMID- 30273258 TI - The Experiences of Younger Individuals Living With Heart Failure. AB - BACKGROUND: Heart failure (HF) impacts 1.7 million Americans between the ages of 20 and 59 years, but limited research exists addressing the issues unique to this age group. OBJECTIVE: The aim of this study was to investigate the experiences of younger persons living with HF. METHODS: Semistructured interviews (n = 18) were analyzed using a qualitative thematic analysis. RESULTS: Six themes emerged: (1) role fulfillment: participants who perceived their roles as a parent, caregiver, spouse, employee, and friend have been negatively affected by HF; (2) autonomy: participants frequently linked their well-being to a sense of independence, productivity, and purpose; (3) financial impact: most of the sample expressed financial instability further complicated by existing disability policies; (4) perception of self: recurrent statements revealed participants feeling judged because of their HF diagnosis and younger age; (5) retrospective life changes: participants reflected on past decisions and often blamed themselves for their current health; and (6) symptom burden: participants reported higher levels of psychosocial symptoms, such as depression, anxiety, and fatigue. CONCLUSIONS: Younger individuals living with HF reported overwhelmingly poor health-related quality of life that was linked to the 6 themes identified previously. The effect of HF was seen on numerous life events that traditionally occur earlier in the life course such as establishing a career, meaningful relationships, family, and financial security. This directly impacted health-related quality of life by disrupting what each individual perceived as important to them, which took a toll on their overall mental health. To provide holistic care to younger patients living with HF, interventions that address the heavy burden of psychosocial symptoms and policy changes associated with financial burden and disability laws must be developed. PMID- 30273259 TI - The Relationship Among Health Beliefs, Depressive Symptoms, Medication Adherence, and Social Support in African Americans With Hypertension. AB - BACKGROUND: African Americans are disproportionately affected by hypertension and have lower medication adherence when compared to other racial groups. Antecedent factors such as beliefs surrounding hypertension, the presence or absence of social support, and depressive symptoms have not been extensively studied collectively in relation to hypertension medication adherence in African Americans. OBJECTIVE: To determine the associations among demographic and clinical factors, depressive symptoms, hypertension beliefs, and social support with blood pressure medication adherence in middle-aged African American adults with a diagnosis of hypertension. METHODS: A cross-sectional study of (N = 120) African Americans (mean age, 49 years; 22.5% men) with a current diagnosis of metabolic syndrome, including hypertension, who reported having and taking a prescribed blood pressure-lowering medication were included. Descriptive statistics, bivariate correlation analysis, and logistic regression using odds ratio were used to examine the effects of high blood pressure beliefs, social support, and depression on medication adherence. RESULTS: A small but significant relationship was found between medication adherence and number of comorbidities (r = 0.19, P = .04). In a multivariate regression model, after controlling for gender, comorbidities remained associated with medication adherence (beta = 0. 77, P = .04). Depressive symptoms, high blood pressure beliefs, and social support did not have a significant relationship with medication adherence. CONCLUSIONS: Multiple comorbidities may have a positive impact upon medication adherence. Further study is needed in a larger sample of African Americans who have a diagnosis of hypertension in addition to other comorbidities requiring medication management. PMID- 30273260 TI - Experiences of Undergoing Enhanced External Counterpulsation in Patients With Refractory Angina Pectoris: A Qualitative Study. AB - BACKGROUND: Enhanced external counterpulsation (EECP) is a noninvasive treatment recommended for patients with refractory angina pectoris (RAP), which generally includes 35 one-hour sessions over 7 weeks. No study has described how patients experience the time before, during, and between sessions, as well as the time after EECP treatment. OBJECTIVE: The aim of this study was to describe how patients with RAP experience EECP treatment. METHODS: Semistructured interviews took place with 15 strategically selected patients (11 men, 58-91 years old) who had finished 7 weeks of EECP at the 2 existing EECP clinics in Sweden. Data were analyzed using inductive qualitative content analysis. RESULTS: The results were divided into 4 content areas, each comprising 3 categories: (1) experiences before EECP was initiated comprised uncharted territory, being given a new opportunity, and gain insight; (2) experiences during EECP sessions comprised physical discomfort, need of distraction, and sense of security; (3) experiences between EECP sessions comprised physical changes, socializing, and coordinating everyday life; and (4) experiences after 1 course of EECP treatment comprised improved physical well-being, improved mental well-being, and maintaining angina in check. CONCLUSIONS: Enhanced external counterpulsation was perceived as an unknown treatment option among these patients with RAP. Nurses should emphasize education before and during treatment based on individualized care needs to improve knowledge and treatment experience, as well as prevent discomfort. There is a great need to increase the awareness of EECP among healthcare professionals because it can improve the life situation for patients with RAP. PMID- 30273262 TI - Anti-DNase I Antibody: A New Serological Reactivity in Primary Sjogren Syndrome. AB - BACKGROUND AND OBJECTIVE: Primary Sjogren syndrome (pSS) is a systemic autoimmune rheumatic disease that particularly affects exocrine glands. Dry eye is one of the most important features of this syndrome, and a recent study reported reduced deoxyribonuclease I (DNase I) activity in the tear of patients with dry eye. We therefore postulated that patients with pSS might have antibodies targeting DNAse I. METHODS: We have evaluated in a cross-sectional study 85 patients with pSS (2002 American-European Consensus Group Criteria), 50 rheumatoid arthritis (RA) patients (1987 American College of Rheumatology Criteria) without sicca symptoms, and 88 healthy volunteers. IgG anti-DNase I was detected by enzyme-linked immunosorbent assay using as antigen bovine pancreas enzyme and confirmed by immunoblotting. RESULTS: Age and sex were alike in the 3 groups (p > 0.05). Anti DNase I was detected in 43.5% of the pSS patients. In contrast, this reactivity was absent in all RA patients (p = 0.0001). Additional comparison of pSS patients with (n = 37) or without (n = 48) anti-DNase I showed that the former group had higher IgG serum levels (2293.2 +/- 666.2 vs 1483.9 +/- 384.6 mg/dL, p = 0.0001) and greater rate of non-drug-induced leukopenia (43% vs 19%, p = 0.02). A multivariate logistic regression analysis identified that only IgG levels were independently associated with anti-DNase I. CONCLUSIONS: We describe a high frequency of anti-DNase I antibodies in pSS patients associated with higher serum IgG levels. The lack of this reactivity in RA patients without sicca symptoms suggests that this antibody may be helpful in the differential diagnosis of these diseases.

PMID- 30273261 TI - Comparison Between Non-High-Density Lipoprotein Cholesterol and Low-Density Lipoprotein Cholesterol to Estimate Cardiovascular Risk Using a Multivariate Model. AB - BACKGROUND: Although studies exist comparing low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (HDL-C) in the development of cardiovascular disease (CVD), most have limitations in the mathematical models used to evaluate their prognostic power adjusted for the other risk factors (cardiovascular risk). OBJECTIVE: The aim of this study was to compare LDL-C and non-HDL-C in patients with CVD to determine whether both parameters predict CVD similarly. METHODS: A cohort of 1322 subjects drawn from the general population of a Spanish region was followed between 1992 and 2006. The outcome was time to CVD. Secondary variables were gender, age, hypertension, diabetes, personal history of CVD, current smoker, body mass index, LDL-C, and non-HDL-C. Two CVD prediction models were constructed with the secondary variables, with only the lipid parameter varying (non-HDL-C or LDL-C). In the construction of the models, the following were considered: multiple imputation, events per variable of 10 or more, and continuous predictors as powers. The validation was conducted by bootstrapping obtaining the distribution of the C statistic (discrimination) and the probabilities observed by smooth curves. These results were compared in both models using graphical and analytical testing. RESULTS: There were a total of 137 CVD events. The models showed no differences in the distributions of the C statistic (discrimination, P = .536) or in the calibration plot. CONCLUSIONS: In our population, LDL-C and non-HDL-C were equivalent at predicting CVD. More studies using this methodology are needed to confirm these results. PMID- 30273264 TI - Atypical Chronic Inflammatory ANCA-Positive Deforming Arthritis After Cocaine Levamisole Exposure. AB - BACKGROUND/OBJECTIVE: Immunostimulatory drugs including immune checkpoint inhibitors and levamisole can induce inflammatory disease including vasculitis, rashes, tissue necrosis, and arthritis. METHODS: This prospective cohort study determined the 5-year outcomes of cocaine-levamisole-induced inflammatory disease as to outcomes and survival. Thirty-one consecutive cocaine-levamisole autoimmune patients and 45 primary vasculitis patients were characterized as to clinical differentiating features, antineutrophil cytoplasmic antibody (ANCA) status, treatment, the presence of acute and chronic arthritis, and 5-year outcome. RESULTS: Seventy-one percent (22/31) of cocaine-levamisole vasculopathy cases were ANCA positive (86% p-ANCA and 14% c-ANCA), whereas 53% (23/45) of the primary vasculitis were ANCA positive (p = 0.04). The ANCA-positive cocaine levamisole cohort at onset were characterized by younger age (45 +/- 12 vs 53 +/- 14 years, p = 0.04), superficial skin necrosis (82% vs 54%, p = 0.036), depressed complement C3 (27% vs 4%, p = 0.33), antiphospholipid antibodies (50% vs 4%, p < 0.001), neutropenia (18% vs 0%, p = 0.044), and elevated antimyeloperoxidase (MPO) antibody levels (100% vs 67%, p < 0.001). Chronic cocaine-levamisole disease was characterized by severe cicatrical deformities of the face and extremities (45.5% vs 8.3%, p = 0.005). Arthralgias (71% vs 82%, p = 0.19) and acute arthritis (33% vs 32%, p = 0.25) were similar between the 2 groups. However, a substantial proportion cocaine-levamisole-induced autoimmune patients (18% vs 0%, p = 0.045) developed a chronic deforming inflammatory arthritis that was rheumatoid factor, anti-cyclic-citrillinated antibody antibody, and HLA-B27 negative, but p-ANCA-and MPO antibody positive. CONCLUSIONS: Patients exposed to cocaine-levamisole may develop serious chronic sequelae including cicatrical cutaneous and facial deformities and an atypical seronegative, p-ANCA and MPO antibody-positive, HLA-B27-negative chronic deforming inflammatory arthritis.

PMID- 30273267 TI - Sustainability of a Tuberculosis Screening Program at an Adult Education Center Through Community-Based Participatory Research. AB - The majority of active tuberculosis (TB) cases in the United States occur through reactivation of latent TB infection among foreign-born individuals. While screening of at-risk individuals through community partnerships is recommended, it is not commonly accomplished. A community-academic partnership developed a TB screening intervention at an adult education center serving a large foreign-born population in Rochester, Minnesota. The intervention was cocreated with grant support by diverse stakeholders through a community-based participatory research partnership. The intervention was sustained beyond the grant interval through adaptation of staffing inputs, a robust partnership with sustained dialogue around TB and operational issues, and adaptation of governance through coownership of the intervention by the adult education center and the public health department. Eight years of data demonstrate that adult education centers may be effective venues for sustaining partnerships to address TB prevention among at-risk communities. PMID- 30273268 TI - Quality Anesthesia: Medicine Measures, Patients Decide. AB - Quality has been defined by six domains: effective, equitable, timely, efficient, safe, and patient centered. Quality of anesthesia care can be improved through measurement, either through local measures in quality improvement or through national measures in value-based purchasing programs. Death directly related to anesthesia care has been reduced, but must be measured beyond simple mortality. To improve perioperative care for our patients, we must take shared accountability for all surgical outcomes including complications, which has traditionally been viewed as being surgically related. Anesthesiologists can also impact public health by being engaged in improving cognitive recovery after surgery and addressing the opiate crisis. Going forward, we must focus on what patients want and deserve: improved patient-oriented outcomes and satisfaction with our care. By listening to our patients and being engaged in the entire perioperative process, we can make the greatest impact on perioperative care. PMID- 30273269 TI - Hospital-, Anesthesiologist-, and Patient-level Variation in Primary Anesthesia Type for Hip Fracture Surgery: A Population-based Cross-sectional Analysis. AB - WHAT WE ALREADY KNOW ABOUT THIS TOPIC: WHAT THIS MANUSCRIPT TELLS US THAT IS NEW: BACKGROUND:: Substantial variation in primary anesthesia type for hip fracture surgery exists. Previous work has demonstrated that patients cared for at hospitals using less than 20 to 25% neuraxial anesthesia have decreased survival. Therefore, the authors aimed to identify sources of variation in anesthesia type, considering patient-, anesthesiologist-, and hospital-level variables. METHODS: Following protocol registration (NCT02787031), the authors conducted a cross sectional analysis of a population-based cohort using linked administrative data in Ontario, Canada. The authors identified all people greater than 65 yr of age who had emergency hip fracture surgery from April 2002 to March 2014. Generalized linear mixed models were used to account for hierarchal data and measure the adjusted association of hospital-, anesthesiologist-, and patient-level factors with neuraxial anesthesia use. The proportion of variation attributable to each level was estimated using variance partition coefficients and the median odds ratio for receipt of neuraxial anesthesia. RESULTS: Of 107,317 patients, 57,080 (53.2%) had a neuraxial anesthetic. The median odds ratio for receiving neuraxial anesthesia was 2.36 between randomly selected hospitals and 2.36 between randomly selected anesthesiologists. The majority (60.1%) of variation in neuraxial anesthesia use was explained by patient factors; 19.9% was attributable to the anesthesiologist providing care and 20.0% to the hospital where surgery occurred. The strongest patient-level predictors were absence of preoperative anticoagulant or antiplatelet agents, absence of obesity, and presence of pulmonary disease. CONCLUSIONS: While patient factors explain most of the variation in neuraxial anesthesia use for hip fracture surgery, 40% of variation is attributable to anesthesiologist and hospital-level practice. Efforts to change practice patterns will need to consider hospital-level processes and anesthesiologists' intentions and behaviors. PMID- 30273270 TI - Self-efficacy as a Mechanism of Action of Imagery Rehearsal Therapy's Effectiveness: An Exploratory Mediation Analysis. AB - Imagery rehearsal therapy (IRT) is an empirically validated therapy targeting recurring nightmares, for which the mechanisms of action remain poorly understood. The objective of this study was to investigate how an exploratory measure of self-efficacy could mediate IRT's effectiveness. Thirty-five victims of sexual assault with recurring nightmares were randomly assigned to either IRT or a control condition. Participants completed questionnaires about self-efficacy and nocturnal symptoms at pre- and posttreatment. Regression analyses showed that IRT predicted greater self-efficacy about dreams (beta = .578) and that self efficacy about dreams predicted improvement in insomnia (beta = -.378). IRT also predicted greater self-efficacy about nightmares (beta = .366), which in turn predicts sleep quality (beta = -.412). However, self-efficacy was not a significant mediator of IRT's effectiveness on insomnia and sleep quality. Although IRT did increase patients' self-efficacy over dreams and nightmares, self-efficacy may not be a primary mechanism of action explaining IRT's effectiveness. PMID- 30273272 TI - Severity, Prevalence, Predictors, and Rate of Identification of Insomnia Symptoms in a Sample of Hospitalized Psychiatric Patients. AB - Insomnia is a risk factor for new onset, exacerbation, and relapse of mental illness. The goal of this study was to examine the prevalence, severity, and predictors of insomnia in hospitalized psychiatric patients. Ninety-seven consecutive psychiatric inpatients were administered the Insomnia Severity Index (ISI) to evaluate the presence and severity of insomnia. Patients' hospital charts were reviewed for demographic and medical information. ISI scores in 79.4% of the patients reached the threshold criterion of 8 for insomnia. Insomnia was not mentioned as a clinical problem in the discharge notes problem list in any of these patients. Multivariate analysis indicated that age (p = 0.009), recent suicide attempt or ideation (P < 0.001), tobacco use (p = 0.024), and recreational drug use during the past month (p = 0.040) were significant predictors of insomnia severity. Insomnia was highly prevalent in this population. Identification and management of insomnia would be an important clinical goal in hospitalized psychiatric patients. PMID- 30273273 TI - Suicide Methods According to Age and Sex: An Analysis of Data of 239,565 Suicide Victims in the Republic of Korea From 1991 to 2015. AB - Because suicide is irreversible, prevention is paramount. For the optimal strategy to reduce lethal means, we sought to investigate age- and sex-associated variations in suicide methods. Data on annual causes of death from 1991 to 2015 in the Republic of Korea were used. Major sociodemographic correlates of the five suicide methods were analyzed by multiple multinominal logistic regression analysis. Among a total of 239,565 suicides from 1991 to 2015, hanging was most common. Gas poisoning sharply increased from 2007 to 2015. The gap between hanging and the second most common method of suicide has increased from 659 in 2004 to 4,433 in 2015. Charcoal burning was most commonly used by males younger than 45 years of age, whereas pesticide was commonly used by both sexes ages 55 years and older. Our results suggest that age- and sex-specific suicide prevention strategies are needed, particularly for gas and pesticide poisoning. PMID- 30273271 TI - Mental Health Impact of Homecoming Experience Among 1730 Formerly Deployed Veterans From the Vietnam War to Current Conflicts Results From the Veterans' Health Study. AB - We examined the effects of homecoming support on current mental health among 1730 deployed veterans from Vietnam, Iraq/Afghanistan, Persian Gulf, and other conflicts. The prevalence of current posttraumatic stress disorder (PTSD) was 5.4%, current depression was 8.3%, and 5.4% had suicidal thoughts in the past month. Overall, 26% of veterans had low homecoming support, which was more prevalent among Vietnam veterans (44.3%, p < 0.001). In multivariable logistic regressions, controlling for demographics, combat exposure, number of deployments, trauma history, and operational theater, low postdeployment support was associated with PTSD (odds ratio, 2.13; p = 0.032) and suicidality (odds ratio, 1.91; p < 0.030), but not depression. For suicidality, an interaction was detected for homecoming by theater status, whereby Iraq/Afghanistan veterans with lower homecoming support had a higher probability of suicidal thoughts (p = 0.002). Thus, years after deployment, lower homecoming support was associated with current PTSD and suicidality, regardless of theater and warzone exposures. For suicidality, lower support had a greater impact on Iraq/Afghanistan veterans. PMID- 30273274 TI - Eating Pathology Among Patients With Anorexia Nervosa and Bulimia Nervosa: The Role of Narcissism and Self-Esteem. AB - We sought to deepen our understanding of the relationship between pathological narcissism and eating disorders (ED) by examining specific facets that composed grandiose and vulnerable narcissism while taking into account self-esteem, a well known and consistent risk factor for ED. Twenty-seven women diagnosed with anorexia nervosa (AN) and 23 women diagnosed with bulimia nervosa (BN) completed standardized measures of pathological narcissism, self-esteem, and dysfunctional eating attitudes and behaviors. Different patterns of associations between the facets of pathological narcissism and eating pathology arose between AN and BN diagnoses. Closer examination of the facets of pathological narcissism revealed that hiding the self, a vulnerable narcissistic facet, contributed significantly to dysfunctional eating attitudes and behaviors over and above self-esteem for women with AN. Hiding the self should continue to be explored in regard to treatment of ED. PMID- 30273275 TI - Is Tapping on Acupuncture Points an Active Ingredient in Emotional Freedom Techniques? A Systematic Review and Meta-analysis of Comparative Studies. AB - Emotional Freedom Techniques (EFTs) combine elements of cognitive restructuring and exposure techniques with acupoint stimulation. Meta-analyses indicate large effect sizes for posttraumatic stress disorder, depression, and anxiety; however, treatment effects may be due to components EFT shares with other therapies. This analysis reviewed whether EFTs acupressure component was an active ingredient. Six studies of adults with diagnosed or self-identified psychological or physical symptoms were compared (n = 403), and three (n = 102) were identified. Pretest vs. posttest EFT treatment showed a large effect size, Cohen's d = 1.28 (95% confidence interval [CI], 0.56 to 2.00) and Hedges' g = 1.25 (95% CI, 0.54 to 1.96). Acupressure groups demonstrated moderately stronger outcomes than controls, with weighted posttreatment effect sizes of d = -0.47 (95% CI, -0.94 to 0.0) and g = -0.45 (95% CI, -0.91 to 0.0). Meta-analysis indicated that the acupressure component was an active ingredient and outcomes were not due solely to placebo, nonspecific effects of any therapy, or nonacupressure components. PMID- 30273276 TI - Cognitive Impairment and Personality Traits in Epilepsy: Characterization and Risk Factor Analysis. AB - Cognitive impairment and personality disorders are severe comorbidities commonly observed in patients with epilepsy, and together they decrease the quality of patients' life. This study aimed to evaluate cognitive function and personality traits in patients with epilepsy with the Wechsler Adult Intelligence Scale Chinese revised and Eysenck Personality Questionnaire and investigate the underlying influencing factors. Compared with the control group, our results showed that patients with epilepsy were presented with significant cognitive impairment and particular personality traits. Epileptic seizure-related factors including earlier age of onset, longer duration of epileptic history, and higher seizure frequency were significantly associated with the observed defects in cognition and personality traits. In addition, the temporal lobe was more likely to affect cognition and personality, and the left hemisphere was closely related to verbal intelligence quotient, which needs to be the focus of future research. These results will be instrumental for guiding the treatment of epilepsy. PMID- 30273278 TI - Effects of Physical Exercise on Depressive Symptoms in Patients With Cognitive Impairment: A Systematic Review and Meta-Analysis. AB - We aimed to evaluate the efficacy of physical exercise in ameliorating depressive symptoms in patients with cognitive impairment. The databases of PubMed, EMBASE, Web of Science, the Cochrane Library, PsycINFO, China National Knowledge Infrastructure, WanFang, and WeiPu (VIP) were searched to identify randomized controlled trials (RCTs) that involved physical exercise for patients with cognitive impairment. A random effects model and a fixed effects model were used to calculate the pooled effect size. Twenty-one studies were identified. The meta analysis showed that physical exercise significantly ameliorated depressive symptoms (standardized mean difference [SMD] = -0.23; 95% confidence interval [CI], -0.39 to -0.07; p = 0.004). In addition, beneficial improvements in neuropsychiatric symptoms (mean difference, -4.62; 95% CI, -9.07 to -0.16, p = 0.04), quality of life (SMD = 0.23; 95% CI, 0.01-0.46; p = 0.04), and activities of daily living (SMD = 0.27; 95% CI, 0.12-0.43; p = 0.0005) were observed in our study. No significant improvements were found in anxiety or apathy. Nevertheless, further high-quality, multicenter RCTs are needed to identify the clinical value of our results. PMID- 30273279 TI - Tattoo Recognition in Screening for Victims of Human Trafficking. AB - There is little information on the secondary prevention of human trafficking and how medical professionals can screen for victims. There is a paucity of validated screening tools for use in clinical settings to identify adult trafficked patients, although one for use in pediatric populations exists. Many victims withhold information about their trafficked status. Because traffickers may mark victims, identification of tattoos provides a useful method for screening patients, which complements history taking, especially when victims are unable to disclose that information. We searched existing medical literature, PsycINFO, PubMed, Google, and JSTOR using keywords "human," "trafficking," and "tattoos." Because there is scant literature on this topic, we also searched the gray literature that enabled preliminary identification of several themes used in trafficking tattoos. We also discussed tattoo placement and quality. Tattoo recognition is a critical factor in identifying victims and setting them on a pathway to freedom and recovery. PMID- 30273277 TI - A Positive Psychology Intervention to Promote Health Behaviors in Heart Failure: A Proof-of-Concept Trial. AB - : Patients with heart failure (HF) frequently struggle to adhere to health behaviors, and psychological factors may contribute to nonadherence. We examined the feasibility and acceptability of a 10-week, positive psychology (PP)-based intervention to promote health behavior adherence in patients (N = 10) with mild to moderate HF and suboptimal health behavior adherence. Participants engaged in weekly phone sessions, completed PP exercises (e.g., writing a gratitude letter, using a personal strength), and set goals related to diet, medication adherence, and physical activity. Feasibility was assessed by the number of sessions completed, and acceptability by participant ratings of ease and utility. Preliminary efficacy was measured by changes in psychological and adherence outcomes. The intervention was feasible (87% of exercises completed) and acceptable. Furthermore, in exploratory analyses, the intervention was associated with improvements in psychological and health behavior adherence outcomes. Larger, randomized trials are needed to further investigate the utility of this intervention. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02938052.

Kinetic analysis of isometric back squats and isometric belt squats. J Strength Cond Res 32(12): 3301-3309, 2018-Belt squats seem to provide an alternative to back squats. However, it is not clear how musculoskeletal loading differs between the two. This study compared lower extremity and low-back kinetics during isometric back squats and isometric belt squats. Sixteen men (age: 22.6 +/- 3.4 years; height: 1.74 +/- 0.11 m; mass: 82.0 +/- 5.6 kg) and 10 women (age: 21.5 +/- 2.5 years; height: 1.64 +/- 0.10 m; mass: 68.9 +/- 7.1 kg) performed isometric back squats and belt squats at 4 squat depths. Joint resultant moments were calculated from kinematic and ground reaction force data. Linear interpolation was used to estimate peak vertical forces and joint moments at a 45 degrees thigh segment angle. Subjects increased peak forces, ankle moments, and knee moments but decreased low-back moments from back to belt squats (p <= 0.023). Hip moments did not significantly change between 2 squats. Subjects demonstrating smaller ankle and knee moments during back squats showed greater increases in these moments from back to belt squats (p <= 0.012, R <= 0.24). Subjects whose back squats were characterized by greater low-back moments displayed greater decreases in low-back moments from back to belt squats (p < 0.001, R = 0.98). Compared with isometric back squats, isometric belt squats may provide a similar or greater external loading for the musculoskeletal system of the lower extremities while reducing external spinal loading. Belt squats may be considered by individuals with upper body or spinal injuries and those displaying excessive external back moments.

Cardiovascular effects of compression garments during uncompensable heat stress. J Strength Cond Res XX(X): 000-000, 2018-This study examined the potential hemodynamic benefits of wearing lower extremity compression garments (CGs) beneath thermal protective clothing (TPC) worn by wildland firefighters, while exercising in a heated environment. Using in a counterbalanced design, 10 male subjects ([mean +/- SD] age 27 +/- 6 years, height 1.78 +/- 0.09 m, body mass 74.8 +/- 7.0 kg, body fat 10.6 +/- 4.2%, and V[Combining Dot Above]O2max 57.8 +/- 9.3 ml.kg.min) completed control (no CG) and experimental (CG) conditions in randomly assigned order. Protocols were separated by a minimum of 3 days. Subjects exercised for 90 minutes (three, 30 minute segments) on a treadmill while wearing wilderness firefighter TPC and helmet in a heated room. Venous blood was drawn before and after exercise to measure hemoglobin (Hgb), hematocrit (Hct), serum osmolarity (OSM), and serum creatine phosphokinase (CPK). Vital signs and perceptual measures of exertion and thermal comfort were recorded during the protocol. Data were analyzed by the paired t-test. There were no differences in the change in heart rate (84 +/- 27 vs. 85 +/- 14 b.min, p = 0.9), core temperature rise (1.8 +/- 0.6 vs. 1.9 +/- 0.5 degrees C, p = 0.39), or body mass lost (-1.72 +/- 0.78 vs. -1.77 +/- 0.58 kg, p = 0.7) between the conditions. There were no differences in the change in Hgb (0.49 +/- 0.66 vs. 0.33 +/- 1.11 g.dl, p = 0.7), Hct (1.22 +/- 1.92 vs. 1.11 +/- 3.62%, p = 0.9), OSM (1.67 +/- 6.34 vs. 6.22 +/- 11.39 mOsm.kg, p = 0.3), or CPK (22.2 +/- 30.2 vs. 29.8 +/- 19.4 IU.L, p = 0.5). Total distance walked (3.9 +/- 0.5 vs. 4.0 +/- 0.5 miles, p = 0.2), exercise interval (88.6 +/- 3.5 vs. 88.4 +/- 3.6 minutes, p = 0.8), and perceptual measures were similar between conditions. Compression garments worn beneath TPC did not acutely alter the physiologic response to exertion in TPC. With greater use in the general public related to endurance activities, the data neither encourage nor discourage CG use during uncompensable heat stress.

Power-force-velocity profiling of sprinting athletes: Methodological and practical considerations when using timing gates. J Strength Cond Res XX(X): 000-000, 2018-The aim of this study was to investigate the impact of timing gate setup on mechanical outputs in sprinting athletes. Twenty-five male and female team sport athletes (mean +/- SD: 23 +/- 4 years, 185 +/- 11 cm, 85 +/- 13 kg) performed two 40-m sprints with maximal effort. Dual-beamed timing gates covered the entire running course with 5-m intervals. Maximal horizontal force (F0), theoretical maximal velocity (v0), maximal horizontal power (Pmax), force-velocity slope (SFV), maximal ratio of force (RFmax), and index of force application technique (DRF) were computed using a validated biomechanical model and based on 12 varying split time combinations, ranging from 3 to 8 timing checkpoints. When no timing gates were located after the 20-m mark, F0 was overestimated (mean difference, +/-90% confidence level: 0.16, +/-0.25 to 0.33, +/-0.28 N.kg; possibly to likely; small), in turn affecting SFV and DRF by small to moderate effects. Timing setups covering only the first 15 m displayed lower v0 than setups covering the first 30-40 m of the sprints (0.21, +/-0.34 to 0.25, +/-0.34 m.s; likely; small). Moreover, poorer reliability values were observed for timing setups covering the first 15-20 m vs. the first 25-40 m of the sprints. In conclusion, the present findings showed that the entire acceleration phase should be covered by timing gates to ensure acceptably valid and reliable sprint mechanical outputs. However, only 3 timing checkpoints (i.e., 10, 20, and 30 m) are required to ensure valid and reliable outputs for team sport athletes.

AB - Hammami, M, Gaamouri, N, Aloui, G, Shephard, RJ, and Chelly, MS. Effects of combined plyometric and short sprint with change-of-direction training on athletic performance of male U15 handball players. J Strength Cond Res XX(X): 000 000, 2018-This study examined the effects of combined plyometric and change-of direction training (CPT) on selected measures of performance (repeated-sprint T test [RSTT], sprint performance [5, 10, 20, and 30 m], change-of-direction tests [modified Illinois test and T-half test], squat jump, countermovement jump, countermovement jump with aimed arms 5-jump test, Y-balance test, Stork balance test, and 20-m shuttle run) in male U15 handball players. Players were randomly divided between experimental (n = 14; age: 14.5 +/- 0.3 years) and control (n = 14; age: 14.6 +/- 0.2 years) groups. All trial participants trained and played matches together, but for 8 weeks in the latter part of the season, the experimental group replaced the tactical part of their normal regimen by a biweekly course of CPT. This induced significant increases in sprint times relative to controls (p = 0.006, effect size [ES] = 0.135, 8.7%; p=<0.001, ES = 0.214, 7.4%; p = 0.022, ES = 0.096, 7.2%; and p = 0.032, ES = 0.085, 8.9% over distances of 5, 10, 20, and 30 m, respectively). The modified Illinois test and T half test also showed significant gains for experimental subjects (p < 0.025; ES = 0.205, 4.2% and p < 0.001; ES = 0.093, 5.3%, respectively), as did vertical and horizontal jumps. However, there were no significant changes of RSTT, 20-m shuttle run, or balance. Nevertheless, we conclude that the current CPT is effective in enhancing sprint performance, change-of-direction tests, and vertical and horizontal jumping and thus it can be commended to male U15 handball players as a useful option for improving important components of their physical performance.

AB - Martin-San Agustin, R, Benitez-Martinez, JC, Medina-Mirapeix, F, and Casana Granell, J. Sex differences and patterns of muscle stiffness in the knee flexor and extensor musculature through analysis of isolated bellies. J Strength Cond Res XX(X): 000-000, 2018-Muscle stiffness (MS) is one of the key factors in joint control. The purpose of this study was to determine sex differences in the MS of 5 isolated muscle bellies (biceps femoris [BF], semitendinosus [ST], rectus femoris [RF], vastus medialis [VM], and vastus lateralis [VL]) and in the pattern of differences among their respective MS. Twenty female and 20 male recreational athletes participated. Muscle stiffness was measured by tensiomyography using maximum radial deformation (Dm) as an indirect indicator of MS. Sex differences were observed only in the Dm of RF (mean difference = 2.07 mm, p < 0.05) when values were adjusted by body mass and stature. Males and females showed a similar pattern in the Dm between the muscle bellies: within the hamstrings, ST had a significantly higher Dm than BF in females (3.02 mm) and males (4.28 mm); within the quadriceps, RF also had a significantly higher value than VL and VM in females (6.50 and 7.38 mm, respectively) and males (4.87 and 4.82 mm, respectively). Sex differences in patterns were found between BF and the vastus muscles: the BF of females had a significantly higher Dm than VL (3.78 mm) and VM (4.51 mm), but this was not observed in males. Differences may imply different involvement of the bellies in countering the movements of the lower extremities. Our results can help to direct exercises to improve the MS in certain muscular bellies.

A systematic review was conducted in 5 electronic databases, with complementary searches in reference lists, and the inclusion criteria were children and adolescents (age group up to 19 years of age) with no special clinical conditions. In all articles, risk of bias was analyzed by a standardized instrument. Of the 5,973 articles initially identified, 21 were included, with data on 22,261 children and adolescents. Higher MF values were associated with lower TG (n = 07) and WC values (n = 15). Different results in relation to the relationship between MF and SBP (n = 10) and MF and DBP (n = 07) were verified. In addition, there was no relationship between MF and FG (n = 06). In addition, inconclusive results were verified in the relationship between MF and HDL-C (n = 07). Concluded higher MF values were related to lower WC values and lower TG concentrations.

Injury prevention programs based on flywheel vs. body weight resistance in recreational athletes. J Strength Cond Res XX(X): 000-000, 2018-This study compares the effect of an isoinertial flywheel technology vs. a traditional gravity-dependent exercise protocol on modifiable factors associated with the incidence of hamstring strain (HAM) and anterior cruciate ligament (ACL) injuries. Furthermore, the effect on repeated sprint ability was also considered. Eighteen recreationally trained volleyball players completed one of the following 6-week protocols: (a) flywheel (FY) included 3 exercises using a YoYo isoinertial-squat machine and 3 exercises with a Versa-Pulley isoinertial device, and (b) gravity-dependent (GT) involved 6 similar exercises with no external resistance (participants' body weight). Both programs consisted in 2 sessions.wk performing 2 sets of 8 repetitions with 2 minutes of rest. Outcomes included a 10-second tuck jump assessment (TJA), landing knee valgus score, hamstring and quadriceps concentric and eccentric isokinetic 60 degrees .s peak torque, optimal peak torque localization, conventional and functional hamstring-to-quadriceps ratio, and 10-m repeated shuttle sprint ability (RSSA) test. FY improved TJA (-2, interquartile range [IQR] = -3 to -1) and valgus (-1, IQR = -1 to 0) scores, hamstring eccentric (20.37, 95% confidence interval [CI] = 9.27-31.47 N.m) and concentric (17.87, 95% CI = 0.40-35.34 N.m) peak torque, as well as the RSSA (-0.28, 95% CI = -0.45 to 0.10 seconds), whereas GT only improved hamstring eccentric peak torque (21.41, 95% CI = 9.00-33.82 N.m). A 6-week protocol using flywheel technology seems to elicit better positive adaptations to protect athletes from HAM and ACL injuries and to enhance RSSA performance compared to exercising with no external resistance other than athletes' body weight.

Resistance training improves a cellular health parameter in obese older women: a randomized controlled trial. J Strength Cond Res XX(X): 000-000, 2018-Phase angle (PhA) is a viable indicator of cellular health, with higher values reflecting better cellularity, cell membrane integrity, and cell function. Adaptive responses to resistance training (RT) on PhA may be important in obese older people. The main purpose of the present study was to investigate the effects of 8 weeks of RT on PhA in obese older women. Thirty-three obese older women (68.1 +/- 5.7 years, 71.6 +/- 10.1 kg, 154.5 +/- 6.7 cm, 30.0 +/- 4.1 kg.m, and 45.0 +/- 6.0% body fat) were randomly allocated into 1 of 2 groups: a training group that performed the RT program (TG, n = 18) or a nonexercise control group (CG, n = 15). The whole-body RT consisted of an 8 week RT program involving 8 exercises performed for 3 sets of 8-12 repetitions 3 times a week. Anthropometric, body fat and fat-free mass, PhA, total body water (TBW), intracellular water (ICW), and extracellular water compartments were performed at before and after training. After the intervention period, the TG presented greater increases (p < 0.05) than CG for fat-free mass (TG = +1.3% and CG = -0.3%), TBW (TG = +2.0% and CG = -1.7%), ICW (TG = +3.1% and CG = -1.9%), and PhA (TG = +3.4% and CG = -1.4%), and lower values for percentage of body fat (TG = -1.3% and CG = +0.9%) and bioimpedance resistance (TG = -4.6% and CG = +2.3%). Our results suggest that 8 weeks of RT improves PhA-a cellular health parameter-in obese older women.

AB - Schmidt, M, Ohlendorf, D, Groneberg, DA, and Wanke, EM. Fit to teach? Cardiorespiratory capacity, vitamin D3, and ferritin in physical education teachers with specialization in dance. J Strength Cond Res XX(X): 000-000, 2018 Numerous studies have shown that good cardiorespiratory capacity is of great importance for a healthy and long-term professional career as a dancer. Although the cardiorespiratory demands during teaching can reach into the submaximal intensity range, current data on the objective physical fitness of this occupational group are still missing. The aim of this pilot project was to determine selected cardiorespiratory parameters. In addition, measurements of the vitamin D3 (25(OH)D3) and iron balance as well as a subjective assessment of dance teachers' (DTs) fitness were performed. Twenty-one DTs (f: n = 18, m: n = 3) aged 48.2 +/- 9.3 years were examined for cardiorespiratory performance within the framework of maximum bicycle spiroergometry. In addition, the self-perception of DTs' fitness was examined as well as the serum vit D3 levels and ferritin concentration in the blood. The cardiorespiratory fitness of DTs can be assessed as average (maximal oxygen consumption, V[Combining Dot Above]O2max = 29.5 +/- 7.1 ml.k.min; physical working capacity, PWCmax = 165.0 +/- 44.4). The DTs seemed to underestimate or overestimate their own capacity. Laboratory diagnostics showed that the 25(OH)D3 levels (21.8 +/- 8.5 ng.ml) and serum ferritin values (102.4 +/- 35.0 g.dl) were not optimal for almost the entire sample. In view of the physical occupational requirements, an increase in aerobic cardiorespiratory fitness by endurance-oriented basic training for DTs seems advisable. In addition, the substitution of vit D3 is worth being discussed. PMID- 30273290 TI - Effects of Lower-Body Muscular Fatigue on Vertical Jump and Balance Performance. AB - Cooper, CN, Dabbs, NC, Davis, J, and Sauls, NM. Effects of lower-body muscular fatigue on vertical jump and balance performance. J Strength Cond Res XX(X): 000 000, 2018-Lower-body fatigue can lead to a decline in vertical jump (VJ) and balance performance due to decreased motor control and coordination. The purpose is to determine the effects of lower-body fatigue on VJ and balance performance. Twenty-four recreationally trained individuals participated in a single 1-hour familiarization and testing session. Participants were familiarized with balance, countermovement vertical jump (CMVJ), and static vertical jump (SVJ) using the Vertec. Three trials of static and dynamic balance tests were completed. Three trials of a SVJ and CMVJ were completed in a randomized order pre/post fatigue protocol. Three trials of double-leg and single-leg tests were performed. Dependent t tests analyzed differences between pre/post fatigue protocol for jumping and balance measures. There was a significant (p < 0.001) difference between pre/post measures for SVJ-H (height), CMVJ-H, and CMVJ peak power (PP). Results showed an interaction (p < 0.05) for group by time for CMVJ-H, CMVJ-peak force (PF), SVJ-PF, and SVJ-PP. There were no main effects (p > 0.05) for time or group for SVJ-rate of velocity development and SVJ-impact force (IF). There were no interactions, time effects, and group effects for balance variables (p > 0.05). Bosco protocol decreased VJ height and PF in SVJ, and VJ height and PF, IF, peak velocity, and PP for CMVJ potentially due to decreased muscle control, coordination, and force-generating capacity after fatigue. Practitioners should consider fatiguing effects on individuals performing jumping motions but it seems that fatigue has no effect on balance.

Acute hormonal response to kettlebell swing exercise differs depending on load, even when total work is normalized. J Strength Cond Res XX(X): 000-000, 2018-This study examined the acute hormonal response to kettlebell (KB) swing exercise using 2 loads, but when total work was equalized. Ten strength-trained males (25 +/- 6 years) completed 2 KB swing trials, with an 8- and 16-kg KB, respectively, in a counterbalanced order. Each protocol lasted 12 minutes comprising 30-second KB swings followed by 30-second rest. Swing cadence was manipulated in each trial to ensure that total weight lifted was the same across conditions. Heart rate (HR) and ratings of perceived exertion (RPE), using the Borg RPE scale 6-20, were taken at the end of each 30 second exercise period. Saliva samples (min 0.5 ml) were taken 15 minutes before, immediately after, and 15 and 30 minutes after each condition from which cortisol (C) and testosterone (T) were determined. Results indicated a significant main effect for load for C (p = 0.007) and T (p = 0.05) where higher values for both C and T were evident for the 16-kg load. There was also a significant main effect for time for T (p = 0.001), where T values were all significantly higher post exercise compared with pre-exercise. For HR, there were significant main effects for load (p = 0.004) and time (p = 0.001) with higher HR seen in 16-kg load and significant increases in HR evident with increasing repetition, irrespective of condition (all p < 0.05). Rating of perceived exertion values increased with repetition for the 8-kg and 16-kg loads, but the increase was more marked for the 16-kg load compared with the 8-kg load (p = 0.002). The present findings suggest that KB swing exercise produces an acute increase in hormones involved in muscle adaptation, but that KB load influences this response, even when total work completed is the same.

AB - Mock, S, Hartmann, R, Wirth, K, Rosenkranz, G, and Mickel, C. Relationship between maximal dynamic force in the deep back squat and sprinting performance in consecutive segments up to 30 m. J Strength Cond Res XX(X): 000-000, 2018-The sprint (in track and field athletics) is characterized by a fluent transition from predominantly knee extending musculature during the initial acceleration phase toward dominance of the hamstring muscle group thereafter. Because of this change in technique, it can be assumed that there is a decrease of correlation of the maximal dynamic force of the deep back squat and sprinting performance with increasing distance. Therefore, sprinting performance for consecutive intervals (0-5, 5-10, 10-15, 15-20, 20-25, and 25-30 m) as well as the 1 repetition maximum (1RM) were determined. Our results show statistically significant (p < 0.01) correlations for both the relationships with the absolute 1RM (r = -0.614 to 0.808) and the relative 1RM (r = -0.646 to -0.749). However, the expected decrease in correlation over distance was not found. The results show that the maximal dynamic force of hip and knee extensors are a basic performance requirement in short-distance sprinting and should be considered in training recommendations.

AB - BACKGROUND Pancreatic cancer causes tremendous mortality across the globe mainly due to late diagnosis and unavailability of efficient chemotheruptic agents. In the current study the anticancer potential of a plant derived alkaloid, Mahanimbine, was examined against a panel of pancreatic cancer cells. MATERIAL AND METHODS The cell proliferation was determined by MTT assay. Annexin V/PI and DAPI staining were performed to detect apoptosis. Cell cycle distribution was investigated by flow cytometery. Cell migration was detected by wound healing assay and protein expression was checked by western blotting. RESULTS The results revealed that Mahanimbine could inhibit the proliferation of the all the pancreatic cancer cells with lower cytoxicity against the normal cells. The IC50 ranged from 3.5 to 64 uM against the pancreatic cancer cell lines. The lowest IC50 of 3.5 uM was observed tor the Capan-2 and SW119 pancreatic cancer cell lines. The anticancer activity of Mahanimbine against the Capan-2 and SW119 cells was found to be due to G0/G1 cell cycle arrest and induction of apoptosis. Mahanimbine prompted apoptosis was also associated with decline in Bcl-2 and enhancement of the Bax expression. Further, it was observed that Mahanimbine could inhibit the AKT/mTOR and STAT3 signalling pathways in the Capan-2 and SW119 pancreatic cancer cells. The effects of the Mahanimbine were also examined on the migration of the Capan-2 and SW119 pancreatic cancer cells. It was found that Mahanimbine could inhibit the motility and migration of both the pancreatic cancer cell lines. CONCLUSIONS We found that Mahanimbine inhibits the proliferation of pancreatic cancer cells and as such Mahanimbine may prove beneficial in the management of pancreatic cancer.

AB - For encapsulated bacteria such as Streptococcus pneumoniae, asymptomatic carriage is more common and longer in duration than disease, and hence is often a more convenient endpoint for clinical trials of vaccines against these bacteria. However, using a carriage endpoint entails specific challenges. Carriage is almost always measured as prevalence, whereas the vaccine may act by reducing incidence or duration. Thus, to determine sample size requirements, its impact on prevalence must first be estimated. The relationship between incidence and prevalence (or duration and prevalence) is convex, saturating at 100% prevalence. For this reason, the proportional effect of a vaccine on prevalence is typically less than its proportional effect on incidence or duration. This relationship is further complicated in the presence of multiple pathogen strains. In addition, host immunity to carriage accumulates rapidly with frequent exposures in early years of life, creating potentially complex interactions with the vaccine's effect. We conducted a simulation study to predict the impact of an inactivated whole cell pneumococcal vaccine-believed to reduce carriage duration-on carriage prevalence in different age groups and trial settings. We used an individual based model of pneumococcal carriage that incorporates relevant immunological processes, both vaccine-induced and naturally acquired. Our simulations showed that for a wide range of vaccine efficacies, sampling time and age at vaccination are important determinants of sample size. There is a window of favorable sampling times during which the required sample size is relatively low, and this window is prolonged with a younger age at vaccination, and in a trial setting with lower transmission intensity. These results illustrate the ability of simulation studies to inform the planning of vaccine trials with carriage endpoints, and the methods we present here can be applied to trials evaluating other pneumococcal vaccine candidates or comparing alternative dosing schedules for the existing conjugate vaccines.

AB - BACKGROUND: Early recognition of dengue, particularly patients at risk for plasma leakage, is important to clinical management. The objective of this study was to build predictive models for dengue, dengue hemorrhagic fever (DHF), and dengue shock syndrome (DSS) using structural equation modelling (SEM), a statistical method that evaluates mechanistic pathways. METHODS/FINDINGS: We performed SEM using data from 257 Thai children enrolled within 72 h of febrile illness onset, 156 with dengue and 101 with non-dengue febrile illnesses. Models for dengue, DHF, and DSS were developed based on data obtained three and one day(s) prior to fever resolution (fever days -3 and -1, respectively). Models were validated using data from 897 subjects who were not used for model development. Predictors for dengue and DSS included age, tourniquet test, aspartate aminotransferase, and white blood cell, % lymphocytes, and platelet counts. Predictors for DHF included age, aspartate aminotransferase, hematocrit, tourniquet test, and white blood cell and platelet counts. The models showed good predictive performances in the validation set, with area under the receiver operating characteristic curves (AUC) at fever day -3 of 0.84, 0.67, and 0.70 for prediction of dengue, DHF, and DSS, respectively. Predictive performance was comparable using data based on the timing relative to enrollment or illness onset, and improved closer to the critical phase (AUC 0.73 to 0.94, 0.61 to 0.93, and 0.70 to 0.96 for dengue, DHF, and DSS, respectively). CONCLUSIONS: Predictive models developed using SEM have potential use in guiding clinical management of suspected dengue prior to the critical phase of illness. PMID- 30273333 TI - A survey of inter-individual variation in DNA methylation identifies environmentally responsive co-regulated networks of epigenetic variation in the human genome. AB - While population studies have resulted in detailed maps of genetic variation in humans, to date there are few robust maps of epigenetic variation. We identified sites containing clusters of CpGs with high inter-individual epigenetic variation, termed Variably Methylated Regions (VMRs) in five purified cell types. We observed that VMRs occur preferentially at enhancers and 3' UTRs. While the majority of VMRs have high heritability, a subset of VMRs within the genome show highly correlated variation in trans, forming co-regulated networks that have low heritability, differ between cell types and are enriched for specific transcription factor binding sites and biological pathways of functional relevance to each tissue. For example, in T cells we defined a network of 95 co regulated VMRs enriched for genes with roles in T-cell activation; in fibroblasts a network of 34 co-regulated VMRs comprising all four HOX gene clusters enriched for control of tissue growth; and in neurons a network of 18 VMRs enriched for roles in synaptic signaling. By culturing genetically-identical fibroblasts under varying environmental conditions, we experimentally demonstrated that some VMR networks are responsive to the environment, with methylation levels at these loci changing in a coordinated fashion in trans dependent on cellular growth. Intriguingly these environmentally-responsive VMRs showed a strong enrichment for imprinted loci (p<10-80), suggesting that these are particularly sensitive to environmental conditions. Our study provides a detailed map of common epigenetic variation in the human genome, showing that both genetic and environmental causes underlie this variation. PMID- 30273335 TI - Amn1 governs post-mitotic cell separation in Saccharomyces cerevisiae. AB - Post-mitotic cell separation is one of the most prominent events in the life cycle of eukaryotic cells, but the molecular underpinning of this fundamental biological process is far from being concluded and fully characterized. We use budding yeast Saccharomyces cerevisiae as a model and demonstrate AMN1 as a major gene underlying post-mitotic cell separation in a natural yeast strain, YL1C. Specifically, we define a novel 11-residue domain by which Amn1 binds to Ace2. Moreover, we demonstrate that Amn1 induces proteolysis of Ace2 through the ubiquitin proteasome system and in turn, down-regulates Ace2's downstream target genes involved in hydrolysis of the primary septum, thus leading to inhibition of cell separation and clumping of haploid yeast cells. Using ChIP assays and site specific mutation experiments, we show that Ste12 and the a1-alpha12 heterodimer are two direct regulators of AMN1. Specifically, a1-alpha2, a diploid-specific heterodimer, prevents Ste12 from inactivating AMN1 through binding to its promoter. This demonstrates how the Amn1-governed cell separation is highly cell type dependent. Finally, we show that AMN1368D from YL1C is a dominant allele in most strains of S. cerevisiae and evolutionarily conserved in both genic structure and phenotypic effect in two closely related yeast species, K. lactis and C. glabrata. PMID- 30273336 TI - Exploring the impact of inoculum dose on host immunity and morbidity to inform model-based vaccine design. AB - Vaccination is an effective method to protect against infectious diseases. An important consideration in any vaccine formulation is the inoculum dose, i.e., amount of antigen or live attenuated pathogen that is used. Higher levels generally lead to better stimulation of the immune response but might cause more severe side effects and allow for less population coverage in the presence of vaccine shortages. Determining the optimal amount of inoculum dose is an important component of rational vaccine design. A combination of mathematical models with experimental data can help determine the impact of the inoculum dose. We illustrate the concept of using data and models to inform inoculum dose determination for vaccines, wby fitting a mathematical model to data from influenza A virus (IAV) infection of mice and human parainfluenza virus (HPIV) infection of cotton rats at different inoculum doses. We use the model to map inoculum dose to the level of immune protection and morbidity and to explore how such a framework might be used to determine an optimal inoculum dose. We show how a framework that combines mathematical models with experimental data can be used to study the impact of inoculum dose on important outcomes such as immune protection and morbidity. Our findings illustrate that the impact of inoculum dose on immune protection and morbidity can depend on the specific pathogen and that both protection and morbidity do not necessarily increase monotonically with increasing inoculum dose. Once vaccine design goals are specified with required levels of protection and acceptable levels of morbidity, our proposed framework can help in the rational design of vaccines and determination of the optimal amount of inoculum. PMID- 30273337 TI - Linking signal detection theory and encoding models to reveal independent neural representations from neuroimaging data. AB - Many research questions in visual perception involve determining whether stimulus properties are represented and processed independently. In visual neuroscience, there is great interest in determining whether important object dimensions are represented independently in the brain. For example, theories of face recognition have proposed either completely or partially independent processing of identity and emotional expression. Unfortunately, most previous research has only vaguely defined what is meant by "independence," which hinders its precise quantification and testing. This article develops a new quantitative framework that links signal detection theory from psychophysics and encoding models from computational neuroscience, focusing on a special form of independence defined in the psychophysics literature: perceptual separability. The new theory allowed us, for the first time, to precisely define separability of neural representations and to theoretically link behavioral and brain measures of separability. The framework formally specifies the relation between these different levels of perceptual and brain representation, providing the tools for a truly integrative research approach. In particular, the theory identifies exactly what valid inferences can be made about independent encoding of stimulus dimensions from the results of multivariate analyses of neuroimaging data and psychophysical studies. In addition, commonly used operational tests of independence are re-interpreted within this new theoretical framework, providing insights on their correct use and interpretation. Finally, we apply this new framework to the study of separability of brain representations of face identity and emotional expression (neutral/sad) in a human fMRI study with male and female participants. PMID- 30273338 TI - High-risk human papillomavirus status and prognosis in invasive cervical cancer: A nationwide cohort study. AB - BACKGROUND: High-risk human papillomavirus (hrHPV) infection is established as the major cause of invasive cervical cancer (ICC). However, whether hrHPV status in the tumor is associated with subsequent prognosis of ICC is controversial. We aim to evaluate the association between tumor hrHPV status and ICC prognosis using national registers and comprehensive human papillomavirus (HPV) genotyping. METHODS AND FINDINGS: In this nationwide population-based cohort study, we identified all ICC diagnosed in Sweden during the years 2002-2011 (4,254 confirmed cases), requested all archival formalin-fixed paraffin-embedded blocks, and performed HPV genotyping. Twenty out of 25 pathology biobanks agreed to the study, yielding a total of 2,845 confirmed cases with valid HPV results. Cases were prospectively followed up from date of cancer diagnosis to 31 December 2015, migration from Sweden, or death, whichever occurred first. The main exposure was tumor hrHPV status classified as hrHPV-positive and hrHPV-negative. The primary outcome was all-cause mortality by 31 December 2015. Five-year relative survival ratios (RSRs) were calculated, and excess hazard ratios (EHRs) with 95% confidence intervals (CIs) were estimated using Poisson regression, adjusting for education, time since cancer diagnosis, and clinical factors including age at cancer diagnosis and International Federation of Gynecology and Obstetrics (FIGO) stage. Of the 2,845 included cases, hrHPV was detected in 2,293 (80.6%), and we observed 1,131 (39.8%) deaths during an average of 6.2 years follow-up. The majority of ICC cases were diagnosed at age 30-59 years (57.5%) and classified as stage IB (40.7%). hrHPV positivity was significantly associated with screen detected tumors, young age, high education level, and early stage at diagnosis (p < 0.001). The 5-year RSR compared to the general female population was 0.74 (95% CI 0.72-0.76) for hrHPV-positive cases and 0.54 (95% CI 0.50-0.59) for hrHPV negative cases, yielding a crude EHR of 0.45 (95% CI 0.38-0.52) and an adjusted EHR of 0.61 (95% CI 0.52-0.71). Risk of all-cause mortality as measured by EHR was consistently and statistically significantly lower for cases with hrHPV positive tumors for each age group above 29 years and each FIGO stage above IA. The difference in prognosis by hrHPV status was highly robust, regardless of the clinical, histological, and educational characteristics of the cases. The main limitation was that, except for education, we were not able to adjust for lifestyle factors or other unmeasured confounders. CONCLUSIONS: In this study, women with hrHPV-positive cervical tumors had a substantially better prognosis than women with hrHPV-negative tumors. hrHPV appears to be a biomarker for better prognosis in cervical cancer independent of age, FIGO stage, and histological type, extending information from already established prognostic factors. The underlying biological mechanisms relating lack of detectable tumor hrHPV to considerably worse prognosis are not known and should be further investigated. PMID- 30273339 TI - Emergency presentation of colorectal patients in Spain. AB - BACKGROUND: Colorectal cancer (CRC) is the leading cause of cancer deaths in Europe. Survival is poorer in patients admitted to hospitals through the emergency department than in electively admitted patients. Knowledge of factors associated with a cancer diagnosis through presentation at an emergency department may reduce the likelihood of an emergency diagnosis. This study evaluated factors influencing the diagnosis of CRC in the emergency department. METHODS AND FINDINGS: This is a cross-sectional study in 5 Spanish regions; subjects were incident cases of CRC diagnosed in 9 public hospitals, between 2006 and 2008. Data were obtained from patient interviews and primary care and hospital clinical records. We found that approximately 40% of CRC patients first contacted a hospital for CRC through an emergency service. Women were more likely than men to be emergency presenters. The type of symptom associated with emergency presentation differed between patients with colon cancer and those with rectal cancer, in that the frequency of "alarm symptoms" was significantly lower in colon than in rectal cancer patients who initially presented to emergency services. Soon after symptom onset, some patients went to a hospital emergency service, whereas others contacted their GP. Lack of contact with a GP for CRC related symptoms was consistently related to emergency presentation. Among patients who contacted a GP, a higher number of consultations for CRC symptoms and any referral to outpatient consultations reduced the likelihood of emergency presentation. All diagnostic time intervals were shorter in emergency presenters than in elective patients. CONCLUSIONS: Emergency presenters are not a uniform category and can be divided into categories according to their symptoms, help seeking behavior trajectory and interaction with their GPs. Time constraints for testing and delays in obtaining outpatient appointments led patients to visit a hospital service either on their own or after referral by their GP. PMID- 30273341 TI - Bile acids drive chemotaxis of Clonorchis sinensis juveniles to the bile duct. AB - Clonorchiasis is a neglected tropical disease caused by Chinese liver fluke, Clonorchis sinensis infection. C. sinensis is a biological carcinogen causing cholangiocarcinoma in humans. In the mammalian host, C. sinensis newly excysted juveniles (CsNEJs) migrate from the duodenum into the bile duct. Bile drives the chemotactic behavior of CsNEJs. Little is known about which components of bile induce the chemotaxis. We designed a chemotaxis assay panel and measured the chemotactic behavior of CsNEJs in response to bile or bile acids. The CsNEJs migrated toward 0.1-1% bile but away from 5-10% bile. The CsNEJs showed strong chemoattraction to cholic acid >=25 mM, but chemorepulsion to lithocholic acid >=0.25 mM. To the CsNEJs, mixture of cholic acid and lithocholic acid was chemoattractive at a ratio greater than 25:1 but chemorepulsive at one smaller than that. Regarding migration in the mammalian hosts, high concentration of lithocholic acid in the gallbladder bile may repel CsNEJs from entering it. However, bile in the hepatic bile duct has a chemoattractive strength of cholic acid but a trace amount of lithocholic acid. Collectively, our results explain why the CsNEJs migrate principally to the hepatic bile ducts, bypassing the gallbladder. PMID- 30273342 TI - Knowledge, attitudes and practices about human African trypanosomiasis and their implications in designing intervention strategies for Yei county, South Sudan. AB - BACKGROUND: A clear understanding of the knowledge, attitudes and practices (KAP) of a particular community is necessary in order to improve control of human African trypanosomiasis (HAT).New screening and diagnostic tools and strategies were introduced into South Sudan, as part of integrated delivery of primary healthcare. Knowledge and awareness on HAT, its new/improved screening and diagnostic tools, the places and processes of getting a confirmatory diagnosis and treatment are crucial to the success of this strategy. METHODOLOGY: A KAP survey was carried out in Yei County, South Sudan, to identify gaps in community KAP and determine the preferred channels and sources of information on the disease. The cross-sectional KAP survey utilized questionnaires, complemented with key informant interviews and a focus group discussion to elicit communal as well as individual KAP on HAT. FINDINGS: Most (90%) of the respondents had general knowledge on HAT. Lower levels of education, gender and geographic locations without a history of HAT interventions were associated with incorrect knowledge and/or negative perceptions about the treatability of HAT. Symptoms appearing in the late stage were best known. A majority (97.2%) would seek treatment for HAT only in a health centre. However, qualitative data indicates that existing myths circulating in the popular imagination could influence people's practices. Seventy-one percent of the respondents said they would offer social support to patients with HAT but qualitative data highlights that stigma still exists. Misconceptions and stigma can negatively influence the health seeking behaviour of HAT cases. In relation to communication, the top preferred and effective source of communication was radio (24%). CONCLUSION: Gaps in relation to KAP on HAT still exist in the community. Perceptions on HAT, specifically myths and stigma, were key gaps that need to be bridged through effective education and communication strategies for HAT control alongside other interventions. PMID- 30273340 TI - Stress susceptibility in Trypanosoma brucei lacking the RNA-binding protein ZC3H30. AB - Trypanosomes rely on post-transcriptional mechanisms and mRNA-binding proteins for control of gene expression. Trypanosoma brucei ZC3H30 is an mRNA-binding protein that is expressed in both the bloodstream form (which grows in mammals) and the procyclic form (which grows in the tsetse fly midgut). Attachment of ZC3H30 to an mRNA causes degradation of that mRNA. Cells lacking ZC3H30 showed no growth defect under normal culture conditions; but they were more susceptible than wild-type cells to heat shock, starvation, and treatment with DTT, arsenite or ethanol. Transcriptomes of procyclic-form trypanosomes lacking ZC3H30 were indistinguishable from those of cells in which ZC3H30 had been re-expressed, but un-stressed bloodstream forms lacking ZC3H30 had about 2-fold more HSP70 mRNA. Results from pull-downs suggested that ZC3H30 mRNA binding may not be very specific. ZC3H30 was found in stress-induced granules and co-purified with another stress granule protein, Tb927.8.3820; but RNAi targeting Tb927.8.3820 did not affect either ZC3H30 granule association or stress resistance. The conservation of the ZC3H30 gene in both monogenetic and digenetic kinetoplastids, combined with the increased stress susceptibility of cells lacking it, suggests that ZC3H30 confers a selective advantage in the wild, where the parasites are subject to temperature fluctuations and immune attack in both the insect and mammalian hosts. PMID- 30273344 TI - A facile hydrothermal approach for catalytic and optical behavior of tin oxide- graphene (SnO2/G) nanocomposite. AB - A cost-effective, facile hydrothermal approach was made for the synthesis of SnO2/graphene (Gr) nano-composites. XRD diffraction spectra clearly confirmed the presence of tetragonal crystal system of SnO2 which was maintaining its structure in both pure and composite materials' matrix. The stretching and bending vibrations of the functional groups were analyzed using FTIR analysis. FESEM images illustrated the surface morphology and the texture of the synthesized sample. HRTEM images confirmed the deposition of SnO2 nanoparticles over the surface of graphene nano-sheets. Raman Spectroscopic analysis was carried out to confirm the in-plane blending of SnO2 and graphene inside the composite matrix. The photocatalytic performance of the synthesized sample under UV irradiation using methylene blue dye was observed. Incorporation of grapheme into the SnO2 sample had increased the photocatalytic activity compared with the pure SnO2 sample. The electrochemical property of the synthesized sample was evaluated. PMID- 30273343 TI - Defining stopping criteria for ending randomized clinical trials that investigate the interruption of transmission of soil-transmitted helminths employing mass drug administration. AB - The current World Health Organization strategy to address soil-transmitted helminth (STH) infections in children is based on morbidity control through routine deworming of school and pre-school aged children. However, given that transmission continues to occur as a result of persistent reservoirs of infection in untreated individuals (including adults) and in the environment, in many settings such a strategy will need to be continued for very extended periods of time, or until social, economic and environmental conditions result in interruption of transmission. As a result, there is currently much discussion surrounding the possibility of accelerating the interruption of transmission using alternative strategies of mass drug administration (MDA). However, the feasibility of achieving transmission interruption using MDA remains uncertain due to challenges in sustaining high MDA coverage levels across entire communities. The DeWorm3 trial, designed to test the feasibility of interrupting STH transmission, is currently ongoing. In DeWorm3, three years of high treatment coverage-indicated by mathematical models as necessary for breaking transmission will be followed by two years of surveillance. Given the fast reinfection (bounce back) rates of STH, a two year no treatment period is regarded as adequate to assess whether bounce-back or transmission interruption have occurred in a given location. In this study, we investigate if criteria to determine whether transmission interruption is unlikely can be defined at earlier timepoints. A stochastic, individual-based simulation model is employed to simulate core aspects of the DeWorm3 community-based cluster-randomized trial. This trial compares a control arm (annual treatment of children alone with MDA) with an intervention arm (community-wide biannual treatment with MDA). Simulations were run for each scenario for both Ascaris lumbricoides and hookworm (Necator americanus). A range of threshold prevalences measured at six months after the last round of MDA and the impact of MDA coverage levels were evaluated to see if the likelihood of bounce-back or elimination could reliably be assessed at that point, rather than after two years of subsequent surveillance. The analyses suggest that all clusters should be assessed for transmission interruption after two years of surveillance, unless transmission interruption can be effectively ruled out through evidence of low treatment coverage. Models suggest a tight range of homogenous prevalence estimates following high coverage MDA across clusters which do not allow for discrimination between bounce back or transmission interruption within 24 months following cessation of MDA. PMID- 30273345 TI - Cost of chronic kidney disease attributable to diabetes from the perspective of the Brazilian Unified Health System. AB - INTRODUCTION: Diabetes is the most common cause of chronic kidney disease, with a high economic impact on health systems. OBJECTIVE: To estimate the cost of chronic kidney disease (CKD) and end-stage kidney disease (ESKD) attributable to diabetes, stratified by sex, race/skin color, and age, from the perspective of the Brazilian public health system between 2010 and 2016. METHODS: Population attributable risk (PAR) was calculated from the Brazilian prevalence of diabetes and the relative risk (or odds ratio) of persons with diabetes developing CKD and ESKD as compared to non-diabetic subjects. The variables of interest were sex, race/skin color, and age. A top-down approach was used to measure the direct costs of the disease reimbursed by the Brazilian Ministry of Health, using data from outpatient and inpatient records. RESULTS: The cost of CKD and ESKD attributable to diabetes in the period 2010-2016 was US$1.2 billion (US$180 million per year) and trending upward. Female sex, age 65-75, and black race/skin color contributed substantially to the costs of CKD and ESKD (US$475 million, US$63 million, and US$25 million respectively). The clinical procedures accounting for the greatest share of disease-attributable costs are hemodialysis and peritoneal dialysis. CONCLUSION: Diabetes accounted for 22% of the costs of CKD and ESKD. Female sex, age 65-75 years, and black race/skin color were the variables which contributed most to disease-related expenditure. The economic burden of CKD may increase gradually in the coming years, with serious implications for the financial sustainability of the Brazilian public health system. PMID- 30273346 TI - An analysis of 3D knee kinematic data complexity in knee osteoarthritis and asymptomatic controls. AB - Three-dimensional (3D) knee kinematic data, measuring flexion/extension, abduction/adduction, and internal/external rotation angle variations during locomotion, provide essential information to diagnose, classify, and treat musculoskeletal knee pathologies. However, and so across genders, the curse of dimensionality, intra-class high variability, and inter-class proximity make this data usually difficult to interpret, particularly in tasks such as knee pathology classification. The purpose of this study is to use data complexity analysis to get some insight into this difficulty. Using 3D knee kinematic measurements recorded from osteoarthritis and asymptomatic subjects, we evaluated both single feature complexity, where each feature is taken individually, and global feature complexity, where features are considered simultaneously. These evaluations afford a characterization of data complexity independent of the used classifier and, therefore, provide information as to the level of classification performance one can expect. Comparative results, using reference databases, reveal that knee kinematic data are highly complex, and thus foretell the difficulty of knee pathology classification. PMID- 30273347 TI - The DEAD-box RNA-binding protein DDX6 regulates parental RNA decay for cellular reprogramming to pluripotency. AB - Cellular transitions and differentiation processes require mRNAs supporting the new phenotype but also the clearance of existing mRNAs for the parental phenotype. Cellular reprogramming from fibroblasts to induced pluripotent stem cells (iPSCs) occurs at the early stage of mesenchymal epithelial transition (MET) and involves drastic morphological changes. We examined the molecular mechanism for MET, focusing on RNA metabolism. DDX6, an RNA helicase, was indispensable for iPSC formation, in addition to RO60 and RNY1, a non-coding RNA, which form complexes involved in intracellular nucleotide sensing. RO60/RNY1/DDX6 complexes formed prior to processing body formation, which is central to RNA metabolism. The abrogation of DDX6 expression inhibited iPSC generation, which was mediated by RNA decay targeting parental mRNAs supporting mesenchymal phenotypes, along with microRNAs, such as miR-302b-3p. These results show that parental mRNA clearance is a prerequisite for cellular reprogramming and that DDX6 plays a central role in this process. PMID- 30273348 TI - In vitro activity of N-acetylcysteine against Stenotrophomonas maltophilia and Burkholderia cepacia complex grown in planktonic phase and biofilm. AB - Stenotrophomonas maltophilia and Burkholderia cepacia complex (Bcc) have been increasingly recognized as relevant pathogens in hospitalized, immunocompromised and cystic fibrosis (CF) patients. As a result of complex mechanisms, including biofilm formation and multidrug resistance phenotype, S. maltophilia and Bcc respiratory infections are often refractory to therapy, and have been associated with a worse outcome in CF patients. Here we demonstrate for the first time that N-acetylcysteine (NAC), a mucolytic agent with antioxidant and anti-inflammatory properties, may exhibit antimicrobial and antibiofilm activity against these pathogens. The antimicrobial and antibiofilm activity of high NAC concentrations, potentially achievable by topical administration, was tested against a collection of S. maltophilia (n = 19) and Bcc (n = 19) strains, including strains from CF patients with acquired resistance traits. Minimum Inhibitory Concentrations (MICs) and Minimum Bactericidal Concentrations (MBCs) ranged from 16 to 32 mg/ml and from 32 to >32 mg/ml, respectively. Sub-MIC concentrations (i.e., 0.25 * MIC) slowed down the growth kinetics of most strains. In time-kill assays, 2-day-old biofilms were more affected than planktonic cultures, suggesting a specific antibiofilm activity of NAC against these pathogens. Indeed, a dose- and time dependent antibiofilm activity of NAC against most of the S. maltophilia and Bcc strains tested was observed, with a sizable antibiofilm activity observed also at 0.5 and 1 * MIC NAC concentrations. Furthermore, at those concentrations, NAC was also shown to significantly inhibit biofilm formation with the great majority of tested strains. PMID- 30273349 TI - Statistical degradation modelling of Poly(D,L-lactide-co-glycolide) copolymers for bioscaffold applications. AB - This methodology permits to simulate the performance of different Poly(D,L lactide-co-glycolide) copolymer formulations (PDLGA) in the human body, to identify the more influencing variables on hydrolytic degradation and, thus, to estimate biopolymer degradation level. The PDLGA characteristic degradation trends, caused by hydrolysis processes, have been studied to define their future biomedical applications as dental scaffolds. For this purpose, the mass loss, pH, glass transition temperature (Tg) and absorbed water mass of the different biopolymers have been obtained from samples into a phosphate-buffered saline solution (PBS) with initial pH of 7.4, at 37 degrees C (human body conditions). The mass loss has been defined as the variable that characterize the biopolymer degradation level. Its dependence relationship with respect to time, pH and biopolymer formulation has been modelled using statistical learning tools. Namely, generalized additive models (GAM) and nonlinear mixed-effects regression with logistic and asymptotic functions have been applied. GAM model provides information about the relevant variables and the parametric functions that relate mass loss, pH and time. Mixed effects are introduced to model and estimate the degradation properties, and to compare the PDLGA biopolymer populations. The degradation path for each polymer formulation has been estimated and compared with respect to the others for helping to use the proper polymer for each specific medical application, performing selection criteria. It was found that the mass loss differences in PDLGA copolymers are strongly related with the way the pH decay versus time, due to carboxylic acid groups formation. This may occur in those environments in which the degradation products remain relatively confined with the non degraded mass. This is the case emulated with the present experimental procedure. The results show that PDLGA polymers degradation degree, in terms of half life and degradation rate, is increasing when acid termination is included, when DL-lactide molar ratio is reduced, decreasing the midpoint viscosity, or when glycolide is not included. PMID- 30273350 TI - STLV-1 co-infection is correlated with an increased SFV proviral load in the peripheral blood of SFV/STLV-1 naturally infected non-human primates. AB - Simian T-Leukemia Virus type 1 and Simian Foamy Virus infect non-human primates. While STLV-1, as HTLV-1, causes Adult T-cell Leukemia/lymphoma, SFV infection is asymptomatic. Both retroviruses can be transmitted from NHPs to humans through bites that allow contact between infected saliva and recipient blood. Because both viruses infect CD4+ T-cells, they might interfere with each other replication, and this might impact viral transmission. Impact of STLV-1 co infection on SFV replication was analyzed in 18 SFV-positive/STLV-1-negative and 18 naturally SFV/STLV-1 co-infected Papio anubis. Even if 9 animals were found STLV-1-positive in saliva, STLV-1 PVL was much higher in the blood. SFV proviruses were detected in the saliva of all animals. Interestingly, SFV proviral load was much higher in the blood of STLV-1/SFV co-infected animals, compared to STLV-1-negative animals. Given that soluble Tax protein can enter uninfected cells, we tested its effect on foamy virus promoter and we show that Tax protein can transactivate the foamy LTR. This demonstrates that true STLV-1 co-infection or Tax only has an impact on SFV replication and may influence the ability of the virus to be zoonotically transmitted as well as its ability to promote hematological abnormalities. PMID- 30273351 TI - Beta-adrenergic activation induces cardiac collapse by aggravating cardiomyocyte contractile dysfunction in bupivacaine intoxication. AB - In order to determine the role of the adrenergic system in bupivacaine-induced cardiotoxicity, a series of experiments were performed. In an animal experiment, male Sprague-Dawley (SD) rats under chloral hydrate anesthesia received intravenous bupivacaine, followed by an intravenous injection of adrenalin or isoprenalin, and the electrocardiogram (ECG), left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), the maximum rate of rise of left ventricular pressure (+dP/dtmax) and the maximum rate of pressure decrease (-dP/dtmax) were continually monitored. In a cellular experiment, freshly isolated adult SD rat ventricular myocytes were perfused with bupivacaine at different concentrations in the presence or absence of isoprenalin, with or without esmolol. The percentage of the sarcomere shortening (bl% peak h), departure velocity (dep v) of sarcomere shortening and time to 50% of the peak speed of myocyte contraction (Tp50) was assessed by a video-based edge-detection system. In an additional experiment, Swiss mice pretreated with saline, isoprenalin, esmolol or dexmedetomidine received bupivacaine to determine the 50% lethal dose (LD50) of bupivacaine. Electron microscopy of myocardial mitochondria was performed to assess damage of these structures. To test mitochondrial reactive oxygen species (ROS) production, freshly isolated SD rat ventricular myocytes were incubated with bupivacaine in the presence of isoprenalin, with or without esmolol. First, our results showed that bupivacaine significantly reduced the LVSP and +dP/dtmax, as well as enhanced the LVEDP and -dP/dtmax (P < 0.05, vs. control, and vs. baseline). Adrenalin and isoprenalin induced a further reduction of LVSP and +dP/dtmax (P < 0.05, vs. before adrenalin or isoprenalin delivery, and vs. control). Second, bupivacaine induced a dose-dependent cardiomyocyte contractile depression. While 5.9 MUmol/L or 8.9 MUmol/L of bupivacaine resulted in no change, 30.0 MUmol/L of bupivacaine prolonged the Tp50 and reduced the bl% peak h and dep v (P < 0.05, vs. control and vs. baseline). Isoprenalin aggravated the bupivacaine-induced cardiomyocyte contractile depression, significantly prolonging the Tp50 (P < 0.05, vs. bupivacaine alone) and reducing the dep v (P < 0.05, vs. bupivacaine alone). Third, esmolol and dexmedetomidine significantly enhanced, while isoprenalin significantly reduced, the LD50 of bupivacaine in mice. Fourth, bupivacaine led to significant mitochondrial swelling, and the extent of myocardial mitochondrial swelling in isoprenalin-pretreated mice was significantly higher than that compared with mice pretreated with saline, as reflected by the higher mitochondrial damage score (P < 0.01). Meanwhile, esmolol pretreatment significantly reduced the mitochondrial damage score (P < 0.01). Fifth, bupivacaine significantly increased the ROS in freshly isolated cardiomyocytes, and added isoprenalin induced a further enhancement of ROS production (P < 0.05, vs. bupivacaine alone). Added esmolol significantly decreased ROS production (P < 0.05, vs. bupivacaine + isoprenalin). Our results suggest that bupivacaine depressed cardiac automaticity, conductivity and contractility, but the predominant effect was contractile dysfunction which resulted from the disruption of mitochondrial energy metabolism. beta-adrenergic activation aggravated the cellular metabolism disorder and therefore contractile dysfunction.

AB - BACKGROUND: In order to understand the role of dengue virus (DENV) specific T cell responses that associate with protection, we studied their frequency and phenotype in relation to clinical disease severity and resolution of viraemia in a large cohort of patients with varying severity of acute dengue infection. METHODOLOGY/PRINCIPAL FINDINGS: Using ex vivo IFNgamma ELISpot assays we determined the frequency of dengue viral peptide (DENV)-NS3, NS1 and NS5 responsive T cells in 74 adult patients with acute dengue infection and examined the association of responsive T cell frequency with the extent of viraemia and clinical disease severity. We found that total DENV-specific and DENV-NS3 specific T cell responses, were higher in patients with dengue fever (DF), when compared to those with dengue haemorrhagic fever (DHF). In addition, those with DF had significantly higher (p = 0.02) DENV-specific T cell responses on day 4 of infection compared to those who subsequently developed DHF. DENV peptide specific T cell responses inversely correlated with the degree of viraemia, which was most significant for DENV-NS3 specific T cell responses (Spearman's r = -0.47, p = 0.0003). The frequency of T cell responses to NS1, NS5 and pooled DENV peptides, correlated with the degree of thrombocytopenia but had no association with levels of liver transaminases. In contrast, total DENV-IgG inversely correlated with the degree of thrombocytopenia and levels of liver transaminases. CONCLUSIONS/SIGNIFICANCE: Early appearance of DENV-specific T cell IFNgamma responses before the onset of plasma leakage, appears to associate with milder clinical disease and resolution of viraemia, suggesting a protective role in acute dengue infection. PMID- 30273355 TI - Cross-cultural emotion recognition and evaluation of Radboud faces database with an Indian sample. AB - Emotional databases are important tools to study emotion recognition and their effects on various cognitive processes. Since, well-standardized large-scale emotional expression database is not available in India, we evaluated Radboud faces database (RaFD)-a freely available database of emotional facial expressions of adult Caucasian models, for Indian sample. Using the pictures from RaFD, we investigated the similarity and differences in self-reported ratings on emotion recognition accuracy as well as parameters of valence, clarity, genuineness, intensity and arousal of emotional expression, by following the same rating procedure as used for the validation of RaFD. We also systematically evaluated the universality hypothesis of emotion perception by analyzing differences in accuracy and ratings for different emotional parameters across Indian and Dutch participants. As the original Radboud database lacked arousal rating, we added this as a emotional parameter along with all other parameters. The results show that the overall accuracy of emotional expression recognition by Indian participants was high and very similar to the ratings from Dutch participants. However, there were significant cross-cultural differences in classification of emotion categories and their corresponding parameters. Indians rated certain expressions comparatively more genuine, higher in valence, and less intense in comparison to original Radboud ratings. The misclassifications/ confusion for specific emotional categories differed across the two cultures indicating subtle but significant differences between the cultures. In addition to understanding the nature of facial emotion recognition, this study also evaluates and enables the use of RaFD within Indian population.

AB - Collective cell migration in cohesive units is vital for tissue morphogenesis, wound repair, and immune response. While the fundamental driving forces for collective cell motion stem from contractile and protrusive activities of individual cells, it remains unknown how their balance is optimized to maintain tissue cohesiveness and the fluidity for motion. Here we present a cell-based computational model for collective cell migration during wound healing that incorporates mechanochemical coupling of cell motion and adhesion kinetics with stochastic transformation of active motility forces. We show that a balance of protrusive motility and actomyosin contractility is optimized for accelerating the rate of wound repair, which is robust to variations in cell and substrate mechanical properties. This balance underlies rapid collective cell motion during wound healing, resulting from a tradeoff between tension mediated collective cell guidance and active stress relaxation in the tissue. PMID- 30273353 TI - meaRtools: An R package for the analysis of neuronal networks recorded on microelectrode arrays. AB - Here we present an open-source R package 'meaRtools' that provides a platform for analyzing neuronal networks recorded on Microelectrode Arrays (MEAs). Cultured neuronal networks monitored with MEAs are now being widely used to characterize in vitro models of neurological disorders and to evaluate pharmaceutical compounds. meaRtools provides core algorithms for MEA spike train analysis, feature extraction, statistical analysis and plotting of multiple MEA recordings with multiple genotypes and treatments. meaRtools functionality covers novel solutions for spike train analysis, including algorithms to assess electrode cross-correlation using the spike train tiling coefficient (STTC), mutual information, synchronized bursts and entropy within cultured wells. Also integrated is a solution to account for bursts variability originating from mixed cell neuronal cultures. The package provides a statistical platform built specifically for MEA data that can combine multiple MEA recordings and compare extracted features between different genetic models or treatments. We demonstrate the utilization of meaRtools to successfully identify epilepsy-like phenotypes in neuronal networks from Celf4 knockout mice. The package is freely available under the GPL license (GPL> = 3) and is updated frequently on the CRAN web-server repository. The package, along with full documentation can be downloaded from: https://cran.r-project.org/web/packages/meaRtools/. PMID- 30273356 TI - Same or different? Theory of mind among children with and without disabilities. AB - Assessing theory of mind (ToM) with reliable and valid measures is important, as ToM plays a significant role in children's social and cognitive functioning. With this in mind, a thorough analysis of the Theory of Mind scale and the Faux Pas Recognition Test was conducted. Over 750 school-age (M age = 7.7) children with disabilities (mild intellectual disability, hearing impairment) and without disabilities took part in our study. The psychometric properties of measures in these groups of children were checked, using confirmatory item factor analysis, reliability, and validity analyses. Thanks to groups' invariance it was possible to compare mean results of children in the groups. Both measures showed well fitted models with acceptable goodness of fit as well as scalar and strict invariance. An IRT analysis showed significant differences in the difficulty of the tasks in all groups, but the same order of passing tasks in comparison to other studies, conducted in Western countries, has been observed. Our results showed that the tasks were the easiest for children without disabilities, and most difficult for children with mild intellectual disability. We obtained significant and positive correlations between ToM and social skills and language abilities. The findings are discussed in relation to results from other studies in the field. PMID- 30273357 TI - The predictors for the non-compliance to follow-up among very low birth weight infants in the Korean neonatal network. AB - The critical need to emphasize preterm infant follow-up after neonatal intensive care unit (NICU) discharge assures early identification of and intervention for neurodevelopmental disability. The aims of this study were to observe the follow up rates in high-risk follow-up clinics, and analyze factors associated with non compliance to follow-up among very low birth weight (VLBW) infants. The data was prospectively collected for 3063 VLBW infants between January 2013 and December 2014 from 57 Korean neonatal network (KNN) centers at a corrected age of 18-24 months. Correlations among demographic data, clinical variables, and neonatal intensive care unit (NICU) volume (divided into 4 quartiles) with the occurrence of non-compliance were analyzed. The overall follow-up rate at the corrected age of 18-24 month was 65.4%. The follow-up rates were inversely related to birth weight and gestational age. Apgar score, hospital stay, maternal age, and maternal education were significantly different between the compliance and non compliance groups. The follow-up rate was higher for mothers with chorioamnionitis, abnormal amniotic fluid, multiple pregnancy, and in vitro fertilization. Infants with respiratory distress syndrome, bronchopulmonary dysplasia, patent ductus arteriosus ligation, periventricular leukomalacia, and retinopathy of prematurity were more common in the compliance group. Follow-up rates showed significant differences according to NICU volume. Using multivariate logistic regression, high birth weight, low NICU volume, siblings, foreign maternal nationality and high 5 min APGAR scores were significant independent factors associated with the non-compliance of VLBW infants for follow-up at 18-24 months of age. This is the first nation-wide analysis of follow-up for VLBW infants in Korea. Understanding factors associated with failure of compliance could help improve the long-term follow-up rates and neurodevelopmental outcomes through early intervention. PMID- 30273358 TI - Mass spectrometry-based lipidomics to explore the biochemical effects of naphthalene toxicity or tolerance in a mouse model. AB - Naphthalene causes mouse airway epithelial injury. However, repeated exposures of naphthalene result in mouse airway tolerance. Previous results showed that toxicity or tolerance was correlated with changes of phosphorylcholine-containing lipids. In this study, a mass spectrometry-based lipidomic approach was applied to examine the effects of naphthalene-induced injury or tolerance in the male ICR mice. The injury model was vehicle x 7 plus 300 mg/kg naphthalene while the tolerant one was 200 mg/kg daily x 7 followed by 300 mg/kg naphthalene on day 8. The lung, liver, kidney, and serum samples were collected for profiles of phosphorylcholine-containing lipids including phosphatidylcholines (PCs) and sphingomyelins (SMs). A partial least-square-discriminate analysis model showed different lung phosphorylcholine-containing lipid profiles from the injured, tolerant, and control groups. Perturbation of diacyl-PCs and plasmenylcholines may be associated with enhanced membrane flexibility and anti-oxidative mechanisms in the lungs of tolerant mice. Additionally, alterations of lyso-PCs and SMs may be responsible for pulmonary dysfunction and inflammation in the lungs of injured mice. Moreover, serum PC(16:0/18:1) has potential to reflect naphthalene-induced airway injuries. Few phosphorylcholine-containing lipid alterations were found in the mouse livers and kidneys across different treatments. This study revealed the changes in lipid profiles associated with the perturbations caused by naphthalene tolerance and toxicity; examination of lipids in serum may assist biomarker development with the potential for application in the human population. PMID- 30273359 TI - Inflammation-associated miR-155 activates differentiation of muscular satellite cells. AB - Tissue renewal and muscle regeneration largely rely on the proliferation and differentiation of muscle stem cells called muscular satellite cells (MuSCs). MuSCs are normally quiescent, but they are activated in response to various stimuli, such as inflammation. Activated MuSCs proliferate, migrate, differentiate, and fuse to form multinucleate myofibers. Meanwhile, inappropriate cues for MuSC activation induce premature differentiation and bring about stem cell loss. Recent studies revealed that stem cell regulation is disrupted in various aged tissues. We found that the expression of microRNA (miR)-155, which is an inflammation-associated miR, is upregulated in MuSCs of aged muscles, and this upregulation activates the differentiation process through suppression of C/ebpbeta, which is an important molecule for maintaining MuSC self-renewal. We also found that Notch1 considerably repressed miR-155 expression, and loss of Notch1 induced miR-155 overexpression. Our findings suggest that miR-155 can act as an activator of muscular differentiation and might be responsible for accelerating aging-associated premature differentiation of MuSCs. PMID- 30273360 TI - Preventative effects of resveratrol and estradiol on streptozotocin-induced diabetes in ovariectomized mice and the related mechanisms. AB - Resveratrol, a non-flavonoid polyphenolic compound, is structurally and functionally similar to estrogen and has drawn great attention for its potentially beneficial effects on diabetes. However, it is not known whether it shares the same protective effect against diabetes as estrogen and the underlying mechanisms. The aim of the present study was to investigate the protective effects of phytoestrogen resveratrol and exogenous 17beta-estradiol against streptozotocin (STZ)-induced type 1 diabetes. Female mice were ovariectomized (OVX) and chronically injected with different concentrations of resveratrol (0.1, 1 or 10 mg/kg) and 17beta-estradiol (0.01, 0.1 or 1 mg/kg) subcutaneously for 4 weeks, and the levels of blood glucose, plasma insulin, plasma antioxidant capacity, the changes of pancreatic islet cells and the expressions of glucose transporter 4 (GLUT4), insulin receptor substrate 1 (IRS-1) and phosphorylation of extracellular signal-regulated kinase (p-ERK) were detected. Resveratrol and 17beta-estradiol significantly inhibited the increase of the blood glucose level and the rise of plasma malondialdehyde in STZ-induced diabetic mice, improved the levels of plasma antioxidant capacity and plasma insulin, protected the pancreatic islet cells, and increased the expressions of GLUT4 and IRS-1, but decreased p-ERK expression in skeletal muscle and myocardial tissue. The results suggest that resveratrol or 17beta-estradiol shows obvious protection against STZ induced diabetes in OVX mice, the mechanisms probably involve their ameliorating antioxidant activities and islet function, promoting muscle glucose uptake and inhibiting the expression of p-ERK. PMID- 30273361 TI - Cytoprotective effect of 2-carbomethoxy-2,3-epoxy-3-prenyl-1,4-naphthoquinone (CMEP-NQ) is mediated by the inhibition of BAK-dependent mitochondrial apoptosis pathway. AB - The inhibitory mechanism of 2-carbomethoxy-2,3-epoxy-3-prenyl-1,4-naphthoquinone (CMEP-NQ) against apoptosis induced by the microtubule-damaging agents (MDAs), nocodazole (NOC) and 2-methoxyestradiol (2-MeO-E2), or a DNA-damaging agent (DDA), camptothecin (CPT) were investigated in human Jurkat T cell clones (J/Neo and J/BCL-XL cells). Treatment of J/Neo cells with NOC, 2-MeO-E2, or CPT caused cytotoxicity and apoptotic DNA fragmentation but these events were significantly attenuated in the presence of CMEP-NQ. Although not only MDA (NOC or 2-MeO-E2) induced mitotic arrest, CDK1 activation, and BCL-2, BCL-XL and BIM phosphorylation, but also DDA (CPT)-induced S-phase arrest and ATM-CHK1/CHK2-p53 pathway activation were not or were barely affected in the presence of CMEP-NQ, the levels of anti-apoptotic BAG3 and MCL-1, which were markedly downregulated after MDA- or DDA-treatment, were rather elevated by CMEP-NQ. Under the same conditions, MDA- or DDA-induced mitochondrial apoptotic events including BAK activation, mitochondrial membrane potential (Deltapsim) loss, caspase-9 activation, and PARP cleavage were significantly inhibited by CMEP-NQ. While MDA- or DDA-induced sub-G1 peak and Deltapsim loss were abrogated in J/BCL-XL cells, MDA-induced mitotic arrest and DDA-induced S-arrest were more apparent in J/BCL XL cells than in J/Neo cells. Simultaneously, the induced cell cycle arrest in J/BCL-XL cells was not significantly disturbed by CMEP-NQ. MDA- or DDA-treatment caused intracellular reactive oxygen species (ROS) production; however, MDA- or DDA-induced ROS production was almost completely abrogated in J/BCL-XL cells. MDA or DDA-induced ROS production in J/Neo cells was significantly suppressed by CMEP-NQ, but the suppressive effect was hardly observed in J/BCL-XL cells. Together, these results show that CMEP-NQ efficiently protects Jurkat T cells from apoptotic cell death via the elevation of BAG3 and MCL-1 levels, which results in the inhibition of intrinsic BAK-dependent mitochondrial apoptosis pathway, as does the overexpression of BCL-XL. PMID- 30273362 TI - Isothermal amplification and rapid detection of Klebsiella pneumoniae based on the multiple cross displacement amplification (MCDA) and gold nanoparticle lateral flow biosensor (LFB). AB - Klebsiella pneumoniae (K. pneumoniae) is a frequent pathogen causing nosocomial infections and outbreaks. We developed a multiple cross displacement amplification (MCDA) assay for the detection of K. pneumoniae, which can get the positive results within 40 minutes' isothermal amplification. Gold-nanoparticle lateral flow biosensor (LFB) and colorimetric indicators were used for the rapid readouts of MCDA amplification. The detection limit of this assay was 100 fg per reaction at 65 degrees C, which was confirmed to be the optimal amplification temperature according to the real time turbidimeters. For specificity, all of the 30 clinical-source K. pneumoniae strains were positive for the MCDA, and all of the non-K. pneumoniae strains belonging to 31 different species were negative for this MCDA assay. To evaluate the practical applicability of this method, we assessed its detection limit for K. pneumoniae strains in sputum samples (24 CFU per reaction), and DNA templates of 100 sputum samples further underwent the MCDA LFB tests. All of the sputum samples being positive for K. pneumoniae (30/100) with the culture method were successfully identified with the MCDA assay, the detection power of which was higher than that of polymerase chain reaction (PCR) (25/100). Thus, the MCDA test for K. pneumoniae combined with the gold nanoparticle LFB as the results readout scheme, are simple, specific, and sensitive methods for the rapid diagnosis of K. pneumoniae in clinical samples. PMID- 30273363 TI - Chronic obstructive pulmonary disease and periprocedural complications in patients undergoing percutaneous coronary interventions. AB - BACKGROUND: The relationship between chronic obstructive pulmonary disease (COPD) and periprocedural complications of percutaneous coronary interventions (PCIs) is influenced by several factors. We aimed to investigate the association between COPD, its complication type and rate in patients undergoing PCI. METHODS: Data were prospectively collected using the Polish Cardiovascular Intervention Society national registry (ORPKI) on all PCIs performed in Poland between January 2015 and December 2016. COPD was present in 5,594 of the 221,187 patients undergoing PCI. We assessed the frequency and predictors of periprocedural complications in PCI. RESULTS: Patients with COPD were elder individuals (70.3 +/- 9.9 vs. 67 +/- 10.8 years; p < 0.05). We noted 145 (2.6%) periprocedural complications in the COPD group and 4,121 (1.9%) in the non-COPD group (p < 0.001). The higher incidence of periprocedural complications in the COPD patients was mainly attributed to cardiac arrest (p = 0.001), myocardial infarctions (p = 0.002) and no-reflows (p < 0.001). COPD was not an independent predictor of all periprocedural complications. On the other hand, COPD was found to be an independent predictor of increased no-reflow risk (odds ratio [OR] 1.447, 95% CI 1.085-1.929; p = 0.01), and at the same time, of decreased risk of periprocedural allergic reactions (OR 0.117, 95% CI 0.016-0.837; p = 0.03). CONCLUSIONS: In conclusion, periprocedural complications of PCIs are more frequent in patients with COPD. COPD is an independent positive predictor of no-reflow and a negative predictor of periprocedural allergic reactions. PMID- 30273364 TI - Obesity alters composition and diversity of the oral microbiota in patients with type 2 diabetes mellitus independently of glycemic control. AB - BACKGROUND AND OBJECTIVE: The involvement of the oral microbiota as a possible link between periodontitis, type 2 diabetes mellitus and obesity is still not well understood. The objective of the study was to investigate if glycemic control and obesity play a role in modulating the composition and diversity of the oral microbial ecology. MATERIAL AND METHODS: A cohort of patients with type 2 diabetes mellitus (n = 18) was recruited. Participants demonstrating improved glycemic control after 3 months (n = 6) were included in a second examination. A full mouth examination was performed to estimate periodontitis severity followed by sample collection (subgingival plaque and saliva). Generation of large sequence libraries was performed using the high-throughput Illumina MiSeq sequencing platform. RESULTS: The majority of participants (94.4%, n = 17) presented with moderate or severe forms of periodontitis. Differences in microbial composition and diversity between obese (BMI >= 30 kg/m2) and non-obese (BMI < 30 kg/m2) groups were statistically significant. Cross-sectional and longitudinal approaches failed to reveal statistically significant associations between HbA1c level and species composition or diversity. CONCLUSIONS: Obesity was significantly associated with the oral microbial composition. The impact of glycemic control on oral microbiota, however, could not be assured statistically. PMID- 30273365 TI - A novel biomarker of laminin turnover is associated with disease progression and mortality in chronic kidney disease. AB - BACKGROUND: Patients with chronic kidney disease (CKD) have increased risk of development of end-stage renal disease (ESRD) and early mortality. Fibrosis is the central pathogenic process in CKD and is caused by dysregulated extracellular matrix (ECM) remodeling. The laminin gamma1 chain (LAMC1) is a core structural protein present in the basement membrane of several organs, including the kidneys. We hypothesized that dysregulation of LAMC1 remodeling could be associated with a higher risk of adverse clinical outcomes in patients with CKD. METHODS: A novel immunoassay targeting LG1M, a specific MMP-9-generated neo epitope fragment of LAMC1, was developed and used to measure the levels of the fragment in urine and serum from 492 patients from the Renal Impairment in Secondary Care (RIISC) study, a prospective cohort of patients with high-risk CKD. Patients were monitored for a median follow-up time of 3.5 years. Associations between serum and urine LG1M levels and progression of CKD at 12 months were assessed by a multivariable logistic regression model. The association with ESRD or mortality was assessed by Kaplan-Meier survival curves and Cox proportional hazards regression. RESULTS: Forty-six (11%) of the 416 patients who reached 12-month follow-up had progression of CKD; during the study follow-up, 125 patients (25.4%) developed ESRD and 71 patients (14.4%) died. Serum and urine levels of LG1M correlated with baseline eGFR (r = -0.43, p<0.0001 and r = -0.17, p = 0.0002, respectively). Serum levels of LG1M were higher in patients with one-year progression of CKD compared to those who did not progress (p<0.01). Baseline serum levels of LG1M were associated with development of ESRD (HR 3.2, 95% CI 1.99-5.2 for patients in the highest LG1M tertile compared to patient in the lowest tertile). Baseline urinary levels of LG1M (uLG1M) were significantly associated with mortality (HR 5.0, 95% CI 2.8-8.9, p<0.0001 for patients in the highest LG1M tertile compared to patients in the lowest tertile). Urine LG1M was retained in the model for prediction of mortality (HR per standard deviation of uLG1M: 1.01, 95% CI 1.00-1.02, p = 0.001). CONCLUSIONS: LG1M, a marker of basement membrane remodeling, is increased in serum and urine of patients with CKD and levels are associated with one-year disease progression, development of ESRD, and mortality. PMID- 30273366 TI - Gelatinase B/matrix metalloproteinase-9 is a phase-specific effector molecule, independent from Fas, in experimental autoimmune encephalomyelitis. AB - Gelatinase B/matrix metalloproteinase-9 (MMP-9) triggers multiple sclerosis (MS) and the animal model of experimental autoimmune encephalomyelitis (EAE) by the breakdown of the blood-brain barrier. Interestingly, MMP-9 is beneficial in systemic autoimmunity caused by Fas-deficiency. Fas-deficient (faslpr) and Fas ligand-deficient mice are protected against EAE. We here investigated the interaction between Fas and MMP-9 in the setting of induction of EAE and compared short- and long-term effects. We provoked EAE with myelin oligodendrocyte glycoprotein (MOG) peptide and compared EAE development in four genotypes (wild type (WT), single knockout mmp-9-/-, faslpr, and mmp-9-/-/faslpr) and monitored leukocytes, cytokines and chemokines as immunological parameters. As expected, faslpr mice were resistant against EAE induction, whereas MMP-9 single knockout mice were not. In the double mmp-9-/-/ faslpr mice the effects on disease scores pointed to independent rather than interrelated disease mechanisms. On a short term, after EAE induction leukocytes infiltrated into the brain and cytokine and chemokine levels were significantly higher in all the four genotypes studied, even in the faslpr and mmp-9-/-/faslpr, which did not develop clinical disease. The levels of MMP-9 but not of MMP-2 were increased in the brain and in the peripheral organs after EAE induction. After 40 days all the animals recovered and did not show signs of EAE. However, the absence of MMP-9 in the remission phase suggested a protective role of MMP-9 in the late phase of the disease, because single mmp-9-/- mice presented a delayed remission in comparison with WT animals suggesting a phase-dependent role of MMP-9 in the disease. Nevertheless, the levels of some cytokines and chemokines remained higher than in control animals even 100 days after EAE induction, attesting to a prolonged state of immune activation. We thus yielded new insights and useful markers to monitor this activated immune status. Furthermore, MMP-9 but not MMP-2 levels remained increased in the brains and, to a higher extend, in the spleens of the WT mice even during the remission phase, which is in line with the role of MMP-9 as a useful marker and a protective factor for EAE in the remission phase. PMID- 30273367 TI - Evaluating the temporal and situational consistency of personality traits in adult dairy cattle. AB - Recent research suggests that personality, defined as consistent individual behavioral variation, in farm animals could be an important factor when considering their health, welfare, and productivity. However, behavioral tests are often performed individually and they might not reflect the behavioral differences manifested in every-day social environments. Furthermore, the contextual and longer-term temporal stability of personality traits have rarely been investigated in adult dairy cattle. In this study, we tested three groups of lactating Holstein cows (40 cows) using an individual arena test and a novel object test in groups to measure the contextual stability of behavior. Among the recorded individual test parameters, we used seven in the final analysis, which were determined by a systematic parameter reduction procedure. We found positive correlations between novel object contact duration in the group test and individual test parameters object contact duration (Rs = 0.361, P = 0.026) and movement duration (Rs = 0.336, P = 0.039). Both tests were repeated 6 months later to investigate their temporal stability whereby four individual test parameters were repeatable. There was no consistency in the group test results for 25 cows tested twice, possibly due to group composition changes. Furthermore, based on the seven individual test parameters, two personality traits (activity/exploration and boldness) were identified by principal component analysis. We found a positive association between the first and second tests for activity/exploration (Rs = 0.334, P = 0.058) and for boldness (Rs = 0.491, P = 0.004). Our results support the multidimensional nature of personality in adult dairy cattle and they indicate a link between behavior in individual and within group situations. The lack of stability according to the group test results implies that group companions might have a stronger influence on individual behavior than expected. We suggest repeating the within-group behavioral measurements to study the relationship between the social environment and the manifestation of personality traits in every-day situations. PMID- 30273368 TI - Influence of peer networks on physician adoption of new drugs. AB - Although physicians learn about new medical technologies from their peers, the magnitude and source of peer influence is unknown. We estimate the effect of peer adoption of three first-in-class medications (dabigatran, sitigliptin, and aliskiren) on physicians' own adoption of those medications. We included 11,958 physicians in Pennsylvania prescribing anticoagulant, antidiabetic, and antihypertensive medications. We constructed 4 types of peer networks based on shared Medicare and Medicaid patients, medical group affiliation, hospital affiliation, and medical school/residency training. Instrumental variables analysis was used to estimate the causal effect of peer adoption (fraction of peers in each network adopting the new drug) on physician adoption (prescribing at least the median number prescriptions within 15 months of the new drug's introduction). We illustrate how physician network position can inform targeting of interventions to physicians by computing a social multiplier. Dabigatran was adopted by 25.2%, sitagliptin by 24.5% and aliskiren by 8.3% of physicians. A 10 percentage point increase in peer adoption in the patient-sharing network led to a 5.90% (SE = 1.50%, p<0.001) increase in physician adoption of dabigatran, 8.32% (SE = 1.51%, p<0.001) increase in sitagliptin, and 7.84% increase in aliskiren adoption (SE = 2.93%, p<0.001). Peer effects through shared hospital affiliation were positive but not significant, and medical group and training network effects were not reliably estimated. Physicians in the top decile of patient-sharing network peers were estimated to have nearly 2-fold stronger influence on their peers' adoption compared to physicians in the top decile of prescribing volume. Limitations include lack of detailed clinical information and pharmaceutical promotion, variables which may influence physician adoption but which are unlikely to bias our peer effect estimates. Peer adoption, especially by those with whom physicians share patients, strongly influenced physician adoption of new drugs. Our study shows the potential for using information on physician peer networks to improve technology diffusion. PMID- 30273369 TI - Pharmacogenetic variation influences sensory neuropathy occurrence in Southern Africans treated with stavudine-containing antiretroviral therapy. AB - BACKGROUND: The use of the HIV antiretroviral drug stavudine (d4T), a thymidine analogue, is associated with the development of mitochondrial toxicities such as sensory neuropathy (SN). Genetic variation in genes relating to d4T transport and metabolism, as well as genetic variation in the thymidine synthesis pathway, could influence occurrence of d4T-related toxicity. METHODS: We examined this hypothesis in a cohort of HIV-positive South African adults exposed to d4T, including 143 cases with SN and 120 controls without SN. Ten SNPs in four genes associated with stavudine transport, and 16 SNPs in seven genes of the thymidine synthesis / phosphorylation pathway were genotyped using Agena mass spectrometry methods. Associations between sensory neuropathy and genetic variants were evaluated using PLINK by univariate and multivariable analyses. RESULTS: Age and height were significantly associated with SN occurrence. Using logistic regression with age and height as covariates, and uncorrected empirical p-values, genetic variation in SLC28A1, SAMHD1, MTHFR and RRM2B was associated with SN in South Africans using d4T. CONCLUSION: Variation in genes relating to d4T transport and metabolism, as well as genetic variation in the thymidine synthesis pathway may influence occurrence of d4T-related SN. These data contribute to the characterisation of African pharmacogenetic variation and its role in adverse response to antiretroviral therapy.

AB - Moral evaluations occur quickly following heuristic-like intuitive processes without effortful deliberation. There are several competing explanations for this. The ADC-model predicts that moral judgment consists in concurrent evaluations of three different intuitive components: the character of a person (Agent-component, A); their actions (Deed-component, D); and the consequences brought about in the situation (Consequences-component, C). Thereby, it explains the intuitive appeal of precepts from three dominant moral theories (virtue ethics, deontology, and consequentialism), and flexible yet stable nature of moral judgment. Insistence on single-component explanations has led to many centuries of debate as to which moral precepts and theories best describe (or should guide) moral evaluation. This study consists of two large-scale experiments and provides a first empirical investigation of predictions yielded by the ADC model. We use vignettes describing different moral situations in which all components of the model are varied simultaneously. Experiment 1 (within subject design) shows that positive descriptions of the A-, D-, and C-components of moral intuition lead to more positive moral judgments in a situation with low stakes. Also, interaction effects between the components were discovered. Experiment 2 further investigates these results in a between-subject design. We found that the effects of the A-, D-, and C-components vary in strength in a high stakes situation. Moreover, sex, age, education, and social status had no effects. However, preferences for precepts in certain moral theories (PPIMT) partially moderated the effects of the A- and C-component. Future research on moral intuitions should consider the simultaneous three-component constitution of moral judgment.

AB - Zero-speed fin stabilizer is applied to reduce the roll motion of ships at zero speed. This paper aims to explore the control strategy of zero-speed fin stabilizer through a composite method of theoretical analysis, simulations and tank tests. The hydrodynamic force model is established using analytical approach and a simplified model is obtained by fitting the CFD simulation data. The control strategy of zero-speed fin stabilizer is obtained based on disturbance and compensation by analyzing the phase matching relationship between the wave disturbance, the roll motion of the ship, the movement of the fin and the fin induced hydrodynamic force. Simulations and water tank tests are performed to verify the effectiveness and feasibility of the obtained control strategies. The results of simulations and tank tests show that the obtained control strategies of zero-speed fin stabilizer based on disturbance and compensation are effective and practical. The proposed method provides theoretical and experimental support for engineering application, and can also be a reference for the controller design of zero-speed fin stabilizers. PMID- 30273371 TI - The impact of BMI on clinical progress, response to treatment, and disease course in patients with differentiated thyroid cancer. AB - INTRODUCTION: Obesity is a serious health problem worldwide, particularly in developed countries. It is a risk factor for many diseases, including thyroid cancer. The relationship between obesity and prognostic factors of thyroid cancer is unclear. AIMS: We sought to ascertain the relationship between body mass index (BMI) and clinicopathological features increasing the risk of poor clinical course, treatment response, and clinical outcome in patients with differentiated thyroid cancer (DTC). SUBJECTS & METHODS: The study included 1181 patients with DTC (88% women and 12% men) treated at a single center from 2000 to 2016. BMI before surgery and aggressive clinicopathological features, according to the American Thyroid Initial Risk stratification system, were analyzed. The relationship between BMI and initial risk, treatment response, and final status of the disease was evaluated, incorporating the revised 2015 American Thyroid Association guidelines and the 8th edition of the American Joint Committee on Cancer/Tumor-Node-Metastasis (AJCC/TNM) staging system. Patients were stratified according to the World Health Organization classification of BMI. Statistical analysis was performed using univariate and multivariate logistic regression analysis. RESULTS: Median follow-up was 7.7 years (1-16 years). There were no significant associations between BMI and extrathyroidal extension (microscopic and gross), cervical lymph node metastasis, or distant metastasis in univariate and multivariate analyses. BMI did not affect initial risk, treatment response or disease outcome. Obesity was more prevalent in men (p = 0.035) and in patients >=55 years old (p = 0.001). There was no statistically significant relationship between BMI and more advanced TNM stage in patients <=55 years old (stage I vs. stage II) (p = 0.266) or in patients >55 years old (stage I-II vs. III-IV) (p = 0.877). CONCLUSIONS: Obesity is not associated with more aggressive clinicopathological features of thyroid cancer. Obesity is not a risk factor for progression to more advanced stages of disease, nor is it a prognostic factor for poorer treatment response and clinical outcome.

AB - OBJECTIVE: To characterize anemia and evaluate hematological responses to universal iron-folic acid (IFA) supplementation in Ethiopian pregnant women. METHOD: A hospital- based prospective follow up study was done between December 2016 and June 2017. Hematological profiles were measured in pregnant women before and after a minimum of one-month IFA supplementation. Mean values and abnormal proportions of hematological profiles were compared before and after supplementation using paired t-test and McNemar test, respectively. Univariate and multivariate analysis were used to analyze the association between independent variables and poor treatment responses. RESULT: Lack of adequate hemoglobin response was found in 48.5%(95/196) of the participants. Prevalence of anemia and low hematocrit value were decreased significantly after IFA supplementation (p = 0.002, and p = 0.001, respectively). Normocytic hypochromic anemia was the commonest form of anemia found in this study followed by normocytic normochromic anemia. There was no statistically significant association between poor hemoglobin responses and all studied factors such as educational level, household size, parity, recent illness, stage of pregnancy, coffee consumption, and duration of iron treatment. CONCLUSION: Our study revealed poor hemoglobin responses in nearly half of the study participants and a high proportion of anemias morphologically atypical of iron deficiency anemia. There is a need to consider anemia attributable to etiologies other than an iron deficiency in anemia intervention programs. PMID- 30273374 TI - Isolated perfused working hearts provide valuable additional information during phenotypic assessment of the diabetic mouse heart. AB - Although murine models for studying the development of cardiac dysfunction in diabetes mellitus are well established, their reported cardiac phenotypes vary. These reported divergences may, in addition to the severity of different models, also be linked to the methods used for cardiac functional assessment. In the present study, we examined the functional changes using conventional transthoracic echocardiography (in vivo) and isolated heart perfusion techniques (ex vivo), in hearts from two mouse models; one with an overt type 2 diabetes (the db/db mouse) and one with a prediabetic state, where obesity was induced by a high-fat diet (HFD). Analysis of left ventricular function in the isolated working hearts from HFD-fed mice, suggested that these hearts develop diastolic dysfunction with preserved systolic function. Accordingly, in vivo examination demonstrated maintained systolic function, but we did not find parameters of diastolic function to be altered. In db/db mice, ex vivo working hearts showed both diastolic and systolic dysfunction. Although in vivo functional assessment revealed signs of diastolic dysfunction, the hearts did not display reduced systolic function. The contrasting results between ex vivo and in vivo function could be due to systemic changes that may sustain in vivo function, or a lack of sensitivity using conventional transthoracic echocardiography. Thus, this study demonstrates that the isolated perfused working heart preparation provides unique additional information related to the development of cardiomyopathy, which might otherwise go unnoticed when only using conventional echocardiographic assessment. PMID- 30273375 TI - Decline in AmpC beta-lactamase-producing Escherichia coli in a Dutch teaching hospital (2013-2016). AB - OBJECTIVE: The objective of this study is to determine the prevalence of rectal carriage of plasmid- and chromosome-encoded AmpC beta-lactamase-producing Escherichia coli and Klebsiella spp. in patients in a Dutch teaching hospital between 2013 and 2016. METHODS: Between 2013 and 2016, hospital-wide yearly prevalence surveys were performed to determine the prevalence of AmpC beta lactamase-producing E. coli and Klebsiella spp. rectal carriage. Rectal swabs were taken and cultured using an enrichment broth and selective agar plates. All E. coli and Klebsiella spp. isolates were screened for production of AmpC beta lactamase using phenotypic confirmation tests and for the presence of plasmid encoded AmpC (pAmpC) genes. E. coli isolates were screened for chromosome-encoded AmpC (cAmpC) promoter/attenuator alterations. RESULTS: Fifty (2.4%) of 2,126 evaluable patients were identified as rectal carrier of AmpC beta-lactamase producing E. coli. No carriage of AmpC beta-lactamase producing Klebsiella spp. was found. Nineteen (0.9%) patients harboured isolates with pAmpC genes and 30 (1,4%) patients harboured isolates with cAmpC promoter/attenuator alterations associated with AmpC beta-lactamase overproduction. For one isolate, no pAmpC genes or cAmpC promotor/attenuator alterations could be identified. During the study period, a statistically significant decline in the prevalence of rectal carriage with E. coli with cAmpC promotor/attenuator alterations was found (p = 0.012). The prevalence of pAmpC remained stable over the years. CONCLUSIONS: The prevalence of rectal carriage of AmpC-producing E. coli and Klebsiella spp. in patients in Dutch hospitals is low and a declining trend was observed for E. coli with cAmpC promotor/attenuator alterations. PMID- 30273378 TI - On-demand route discovery in a unicast manner. AB - While having high bandwidth-efficiency, the ad-hoc on-demand distance vector (AODV) routing protocol suffers from high signaling overhead due to route request (RREQ) messages flooding, especially when the node density and the number of connections are increased. In order to resolve this broadcast storm problem of the AODV in a high node density mobile ad-hoc network, we propose a geographical on-demand route discovery scheme. Assuming a known location of the destination, the RREQ of the proposed routing protocol is propagated in a unicast manner by employing a novel parsing mechanism for possible duplicate RREQs. The routing overhead of the proposed routing protocol is greatly robust to the node density change. We derive the node density required for the proposed routing protocol to keep the same connectivity as the AODV under the circumstance where the nodes are uniformly distributed. In addition, we present an imaginary destination consideration method to incorporate the uncertainty of the destination's location due to mobility. Computer simulations show that the proposed scheme enables the RREQ propagation to cover 95% of the one-hop communication area centered at the originally known location of the destination without sacrificing the unicast feature. PMID- 30273377 TI - Different culture media modulate growth, heterogeneity, and senescence in human mammary epithelial cell cultures. AB - The ability to culture normal human mammary epithelial cells (HMEC) greatly facilitates experiments that seek to understand both normal mammary cell biology and the many differences between normal and abnormal human mammary epithelia. To maximize in vivo relevance, the primary cell culture conditions should maintain cells in states that resemble in vivo as much as possible. Towards this goal, we compared the properties of HMEC strains from two different reduction mammoplasty tissues that were grown in parallel using different media and culture conditions. Epithelial organoids were initiated into three different media: two commonly used serum-free-media, MCDB 170-type (e.g. MEGM) and WIT-P, and a low stress media, M87A. Growth, lineage heterogeneity, p16 protein expression, and population doublings to senescence were measured for each culture condition. MCDB 170 caused rapid senescence and loss of heterogeneity within 2 to 3 passages, but some cultures went through the 1 to 2 month process of selection to generate clonal finite post-selection post-stasis cells. WIT-P caused impressive expansion of luminal cells in 2nd passage followed by their near complete disappearance by passage 4 and senescence shortly thereafter. M87A supported as much as twice the number of population doublings compared to either serum-free medium, and luminal and myoepithelial cells were present for as many as 8 passages. Thus, of the three media compared, WIT-P and MCDB 170 imposed rapid senescence and loss of lineage heterogeneity, phenotypes consistent with cells maintained in high-stress conditions, while M87A supported cultures that maintained multiple lineages and robust growth for up to 60 population doublings. In conjunction with previous studies examining the molecular properties of cultures grown in these media, we conclude that M87A medium is most able to support long-term culture of multiple lineages similar to in vivo conditions, thereby facilitating investigations of normal HMEC biology relevant to the mammary gland in situ. PMID- 30273376 TI - MRI-guided intracerebral convection-enhanced injection of gliotoxins to induce focal demyelination in swine. AB - Demyelinating disorders such as multiple sclerosis (MS) or transverse myelitis are devastating neurological conditions with no effective cure. Prevention of myelin loss or restoration of myelin are key for successful therapy. To investigate the disease and develop cures animal models with good clinical relevance are essential. The goal of the current study was to establish a model of focal demyelination in the brain of domestic pig using MRI-guided gliotoxin delivery. The rationale for developing a new myelin disease model in the domestic pig was based on the fact that the brain in pigs is anatomically and histologically much more similar to that of humans compared to the rodent brain. For MRI-assisted gliotoxin injection, eight 30 kg pigs were subjected to treatment with lysolecithin (20, 30 mg/ml); or with ethidium bromide (0.0125, 0.05, 0.2 mg/ml). Animals were placed in an MRI scanner for intraparenchymal targeting of gliotoxin into the corona radiata (250 MUl over 1h), with real-time monitoring of toxin distribution on T1 scans and monitoring of lesion evolution over seven days using both T1 and T2 scans. After the last MRI, animals were transcardially perfused and brains were processed for histological and immunofluorescent analysis. Gadolinium-enhanced T1 MRI during injection demonstrated biodistribution of the contrast (as a surrogate marker for toxin distribution) and its diffusion through the brain parenchyma. Lesion induction was confirmed on T2-weighted MRI and histopathology, thus enabling the establishment of optimal doses of gliotoxins. To conclude, MRI-guided focal demyelination in swine is accurate and provides real-time confirmation of gliotoxin, thus facilitating placement of focal lesions with high precision. This new model of focal demyelination can be used for further investigation and development of novel therapeutic approaches. PMID- 30273379 TI - Regulation of the NRF2 transcription factor by andrographolide and organic extracts from plant endophytes. AB - The transcription factor NF-E2 Related Factor-2 (NRF2) is an important drug target. Activation of NRF2 has chemopreventive effects in cancer and exerts beneficial effects in a number of diseases, including neurodegenerative diseases, inflammatory diseases, hepatosteatosis, obesity and insulin resistance. Hence, there have been great efforts to discover and characterize novel NRF2 activators. One reported NRF2 activator is the labdane diterpenoid andrographolide. In this study, we identified the mechanism through which andrographolide activates NRF2. We showed that andrographolide inhibits the function of KEAP1, a protein that together with CUL3 and RBX1 forms an E3 ubiquitin ligase that polyubiquitinates NRF2. Andrographolide partially inhibits the interaction of KEAP1 with CUL3 in a manner dependent on Cys151 in KEAP1. This suggests that andrographolide forms Michael acceptor dependent adducts with Cys151 in KEAP1 in vivo, leading to inhibition of NRF2 ubiquitination and consequently accumulation of the transcription factor. Interestingly, we also showed that at higher concentrations andrographolide increases NRF2 protein expression in a Cys151 independent, but likely KEAP1 dependent manner, possibly through modification of other Cys residues in KEAP1. In this study we also screened secondary metabolites produced by endophytes isolated from non-flowering plants for NRF2-inducing properties. One of the extracts, ORX 41, increased both NRF2 protein expression and transcriptional activity markedly. These results suggest that endophytes isolated from non-flowering or other plants may be a good source of novel NRF2 inducing compounds. PMID- 30273380 TI - Meta-analysis of the association between the inflammatory potential of diet and urologic cancer risk. AB - BACKGROUND: The inflammatory potential of diet has been shown to have an association with the risk of several cancer types, but the evidence is inconsistent regarding the related risk of urologic cancer (UC). Therefore, we conducted the present meta-analysis to investigate the association between the inflammatory potential of diet and UC. METHODS: PubMed, Embase and Web of Science were searched up to July 31, 2018. Two reviewers independently selected the studies and extracted the data. The pooled risk ratio (RR) and its 95% confidence interval (CI) were calculated using the Stata12.0 software package. RESULTS: Nine case-control studies and three cohort studies including 83,197 subjects met the inclusion criteria. The overall meta-analysis results showed that individuals with the highest category of DII (dietary inflammatory index) were associated with an increased risk of prostate cancer (RR = 1.62, 95% CI: 1.30-2.02); subgroup analysis showed consistent results. For kidney and bladder cancer, significant positive associations were found in individuals with the highest category of DII score; however, no significant association was found between DII and the risk of urothelial cell carcinoma (UCC). CONCLUSION: Available data suggest that more pro-inflammatory diets are associated with an increased risk of prostate cancer, kidney cancer and bladder cancer. However, further well designed large-scaled cohort studies are warranted to provide more conclusive evidence. PMID- 30273381 TI - Knowledge of preconception care among healthcare providers working in public health institutions in Hawassa, Ethiopia. AB - BACKGROUND: Preconception care (PCC) is an evidence-based health promotion intervention to prevent adverse pregnancy outcomes. Nevertheless, it is one of the missing elements within the continuum of maternal and child healthcare. Despite the WHO's recommendation, most of the developing countries have not yet started implementing preconception care. OBJECTIVE: To determine the knowledge level of healthcare providers about PCCand to identify predictors of effective knowledge of preconception care. METHOD: This is a cross-sectional study conducted among 634 healthcare providers (HCP) working in public health institutions of Hawassa. A pilot-tested and validated self-administered survey tool was used to collect data from individual healthcare providers who were selected randomly using a multistage sampling technique. The data entry and analysis were conducted using SPSS version 20 software. Frequency, proportions, means and standard deviations were used to describe the data. Bivariate and multivariate logistic regression models were implemented to determine the predictors of HCP's PCC knowledge. RESULTS: Only a few (31%) of the healthcare providers demonstrated a good level of knowledge on preconception care. The odds of having good PCC knowledge was high among HCPs working in hospitals (AOR = 1.8, 95% C.I. 1.3-2.6), HCPs using their smart phone to access clinical resources (AOR = 1.4, 95% C.I. 1.1-2.0), among those HCPs ever have read PCC guideline prepared by organization outside of Ethiopia (AOR = 1.9, 95% C.I. 1.4-2.7), among those who claimed practicing PCC (AOR = 3.4, 95% C.I. 2.0-5.9), and among those who earn salary of >= 146.0 $(AOR = 1.5, 95% C.I. 1.1-2.1). CONCLUSION: There is an unacceptably low level of knowledge about PCC among most of the healthcare providers in public health facilities in Ethiopia. The predictors identified in this study can be used to enhance the knowledge of healthcare providers about preconception care. PMID- 30273382 TI - Diagnostic value of STAF score in combination with D-dimer in cardioembolism. AB - The aim of this study was to evaluate the diagnostic value of the Score for the Targeting of Atrial Fibrillation (STAF) in combination with the serum D-dimer (DD) levels in cardioembolism(CE).This study was a retrospective case-onlystudy, consecutively including patients with acute ischemic stroke. All patients were evaluated following the STAF scoring criteria and were classified according to the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) etiology classification criteria. A total of 317 patients were enrolled, including 37 CE cases (11.67%). STAF >=5 showed a sensitivity of 89% and a specificity of 91% for the diagnosis of CE, whereas DD >791.30 ng/mL had a sensitivity of 58% and a specificity of 78%. When the STAF was used in combination with the DD level, the sensitivity was 95%, and the specificity was 100%.STAF score is an excellent tool for the diagnosis of CE when combined with DD, and can facilitate the etiological classification of acute ischemic stroke. PMID- 30273383 TI - A stochastic model of myeloid cell lineages in hematopoiesis and pathway mutations in acute myeloid leukemia. AB - A model for hematopoiesis is presented that explicitly includes the erythrocyte, granulocyte, and thrombocyte lineages and their common precursors. A small number of stem cells proliferate and differentiate through different compartments to produce the vast number of blood cells needed every day. Growth factors regulate the proliferation of cells dependent on the current demand. We provide a steady state analysis of the model and rough parameter estimates. Furthermore, we extend the model to include mutations that alter the replicative capacity of cells and introduce differentiation blocks. With these mutations the model develops signs of acute myeloid leukemia. PMID- 30273384 TI - Laplacian mixture modeling for network analysis and unsupervised learning on graphs. AB - Laplacian mixture models identify overlapping regions of influence in unlabeled graph and network data in a scalable and computationally efficient way, yielding useful low-dimensional representations. By combining Laplacian eigenspace and finite mixture modeling methods, they provide probabilistic or fuzzy dimensionality reductions or domain decompositions for a variety of input data types, including mixture distributions, feature vectors, and graphs or networks. Provable optimal recovery using the algorithm is analytically shown for a nontrivial class of cluster graphs. Heuristic approximations for scalable high performance implementations are described and empirically tested. Connections to PageRank and community detection in network analysis demonstrate the wide applicability of this approach. The origins of fuzzy spectral methods, beginning with generalized heat or diffusion equations in physics, are reviewed and summarized. Comparisons to other dimensionality reduction and clustering methods for challenging unsupervised machine learning problems are also discussed. PMID- 30273385 TI - Trust-based altruism facing new contexts: The Vyegwa-Gika pygmies from Burundi. AB - The community of Pygmies settled in Vyegwa-Gika provides an exceptional case study to test the role of trust in the evolution of altruism. The Vyegwa-Gika Pygmies were forced to migrate from rainforests to the savanna, changing quickly their environment, culture, and socio-economic situation. Despite the high level of poverty they suffer in this new settlement, we found evidence of strong altruistic attitudes toward trustees when playing an economic game. In addition, Vyegwa-Gika Pygmies keep small personal trust networks despite the fact they share frequent social interactions within the community. These results indicate the great effectiveness of personal trust in fostering altruism, even if the circumstances make it difficult to establish such kind of affective bonds. A theory of the evolution of altruism should therefore also account for the evolution of psychology of trust, as a key element in the process. PMID- 30273388 TI - The eCura system as a novel indicator for the necessity of salvage surgery after non-curative ESD for gastric cancer: A case-control study. AB - Endoscopic submucosal dissection (ESD) for early gastric cancer does not always lead to complete cancer resection. The aim of this study was to determine indicators for cancer residue (CR) status in cases of non-curative ESD. We analyzed 47 cases of non-curative ESD followed by salvage surgery and collected data regarding the rates of CR, which included both local CR and lymph node metastasis (LNM). To elucidate the risk factors for CR status, we compared the CR positive and the CR negative groups among surgical specimens according to the following variables obtained from ESD findings: tumor location, tumor size, depth of invasion, lympho-vascular invasion, histological margin, and histological diagnosis. The eCura system, which is an LNM risk scoring system, was also applied and scores were calculated in each case as follows: 3 points for lymphatic invasion and 1 point each for tumor size >30 mm, positive vertical margin, venous invasion, and submucosal invasion >=500 MUm. There were 9 (19%) CR positive cases, which included 6 cases of local CR and 4 cases of LNM; no cancer was detected in over 80% of the patients. The eCura scoring system was the only significant factor for CR status: the higher the eCura score, the greater the CR positivity (p = 0.0128). In particular, all patients in the low-risk group (score = 0-1 point) had no CR. Although no cancer recurrence was observed during a median follow-up of 4 years, 2 patients died of pneumonia. In conclusion, the eCura system might make it possible to select appropriate cases for salvage surgery.

AB - Cyanobacteria contribute to the ecology of various marine environments, also for their symbioses, since some of them are common hosts of sponges and ascidians. They are also emerging as an important source of novel bioactive secondary metabolites in pharmacological (as anticancer drugs) and biotechnological applications. In the present work we isolated a cyanobacteria in a free-living state from leaves of the seagrass Posidonia oceanica leaves. This newly collected strain was then cultivated under two laboratory conditions, and then characterized by combining morphological observation and molecular studies based on 16S rRNA gene sequences analysis. The strain showed 99% pairwise sequence identity with Halomicronema metazoicum ITAC101, never isolated before as a free living organisms, but firstly described as an endosymbiont of the Mediterranean marine spongae Petrosia ficiformis, under the form of a filamentous strain. Further studies will investigate the actual role of this cyanobacterium in the leaf stratum of P. oceanica leaves, given its demonstrated ability to influence the vitality and the life cycle of other organisms. In fact, its newly demonstrated free-living stage, described in this study, indicate that Phormidium like cyanobacteria could play important roles in the ecology of benthic and planktonic communities. PMID- 30273386 TI - Lack of vitamin D signalling per se does not aggravate cardiac functional impairment induced by myocardial infarction in mice. AB - Epidemiological studies have linked vitamin D deficiency to an increased incidence of myocardial infarction and support a role for vitamin D signalling in the pathophysiology of myocardial infarction. Vitamin D deficiency results in the development of secondary hyperparathyroidism, however, the role of secondary hyperparathyroidism in the pathophysiology of myocardial infarction is not known. Here, we aimed to explore further the secondary hyperparathyroidism independent role of vitamin D signalling in the pathophysiology of myocardial infarction by inducing experimental myocardial infarction in 3-month-old, male, wild-type mice and in mice lacking a functioning vitamin D receptor. In order to prevent secondary hyperparathyroidism in vitamin D receptor mutant mice, all mice were maintained on a rescue diet enriched with calcium, phosphorus, and lactose. Surprisingly, survival rate, cardiac function as measured by echocardiography and intra-cardiac catheterisation and cardiomyocyte size were indistinguishable between normocalcaemic vitamin D receptor mutant mice and wild-type controls, 2 and 8 weeks post-myocardial infarction. In addition, the myocardial infarction induced inflammatory response was similar in vitamin D receptor mutants and wild type mice, as evidenced by a comparable upregulation in cardiac interleukin-1 beta and tumor-necrosis-factor-alpha mRNA abundance and similar elevations in circulating interleukin-1-beta and tumor-necrosis-factor-alpha. Our data suggest that the lack of vitamin D signalling in normocalcaemic vitamin D receptor mutants has no major detrimental effect on cardiac function and outcome post myocardial infarction. Our study may have important clinical implications because it suggests that the secondary hyperparathyroidism induced by vitamin D deficiency, rather than the lack of vitamin D signalling per se, may negatively impact cardiac function post-myocardial infarction. PMID- 30273391 TI - Light control of G protein signaling pathways by a novel photopigment. AB - Channelopsins and photo-regulated ion channels make it possible to use light to control electrical activity of cells. This powerful approach has lead to a veritable explosion of applications, though it is limited to changing membrane voltage of the target cells. An enormous potential could be tapped if similar opto-genetic techniques could be extended to the control of chemical signaling pathways. Photopigments from invertebrate photoreceptors are an obvious choice-as they do not bleach upon illumination -however, their functional expression has been problematic. We exploited an unusual opsin, pScop2, recently identified in ciliary photoreceptors of scallop. Phylogenetically, it is closer to vertebrate opsins, and offers the advantage of being a bi-stable photopigment. We inserted its coding sequence and a fluorescent protein reporter into plasmid vectors and demonstrated heterologous expression in various mammalian cell lines. HEK 293 cells were selected as a heterologous system for functional analysis, because wild type cells displayed the largest currents in response to the G-protein activator, GTP-gamma-S. A line of HEK cells stably transfected with pScop2 was generated; after reconstitution of the photopigment with retinal, light responses were obtained in some cells, albeit of modest amplitude. In native photoreceptors pScop2 couples to Go; HEK cells express poorly this G-protein, but have a prominent Gq/PLC pathway linked to internal Ca mobilization. To enhance pScop2 competence to tap into this pathway, we swapped its third intracellular loop important to confer specificity of interaction between 7TMDRs and G-proteins-with that of a Gq-linked opsin which we cloned from microvillar photoreceptors present in the same retina. The chimeric construct was evaluated by a Ca fluorescence assay, and was shown to mediate a robust mobilization of internal calcium in response to illumination. The results project pScop2 as a potentially powerful optogenetic tool to control signaling pathways. PMID- 30273392 TI - Transcriptome analyses of Atlantic salmon muscle genes induced by a DNA vaccine against salmonid alphavirus, the causative agent of salmon pancreas disease (PD). AB - Salmonid alphavirus (SAV) is the causative agent of pancreas disease (PD) in farmed Atlantic salmon. A previous study showed that vaccination of pre-smolt salmon with a plasmid encoding the structural polypeptide of SAV gave protection against infection and development of PD accompanied by production of antibodies against the virus. In the present work we analyzed transcript responses in the muscle to vaccination with this plasmid (here named pSAV). The purpose was to shed light on how pSAV might initiate adaptive immune responses in the fish. The work was based on microarray and reverse transcription quantitative PCR analyses of muscle at the injection site 7 days after vaccination. The results showed that pSAV and pcDNA3.3 had similar abilities to up-regulate type I IFN stimulated genes. In contrast, pSAV caused higher up-regulation of IFNgamma and several IFNgamma inducible genes. Compared to pcDNA3.3, pSAV also gave larger increase in transcripts of marker genes for B-cells, T-cells and antigen presenting cells (APCs), which suggest attraction and role of these cells in the adaptive immune responses elicited by pSAV. Moreover, pSAV caused a stronger up-regulation of the chemokine CXCL10 and the proinflammatory cytokines IL-1beta and TNFalpha, which may explain attraction of lymphocytes and APCs. The present work shows that the expression profile of genes resulting from vaccination with pSAV is different from the expression profiles obtained previously by vaccination of salmonids with DNA vaccines against infectious salmon anemia virus and infectious hematopoietic necrosis virus.

AB - BACKGROUND: Hydrocephalus is a debilitating disorder, affecting all age groups. Evaluation of its global epidemiology is required for healthcare planning and resource allocation. OBJECTIVES: To define age-specific global prevalence and incidence of hydrocephalus. METHODS: Population-based studies reporting prevalence of hydrocephalus were identified (MEDLINE, EMBASE, Cochrane, and Google Scholar (1985-2017)). Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Two authors reviewed abstracts, full text articles and abstracted data. Metanalysis and meta-regressions were used to assess associations between key variables. Heterogeneity and publication bias were assessed. Main outcome of interest was hydrocephalus prevalence among pediatric (<= 18 years), adults (19-64 years), and elderly (>= 65) patients. Annual hydrocephalus incidence stratified by country income level and folate fortification requirements were obtained (2003-2014) from the International Clearinghouse for Birth Defects Surveillance and Research (ICBDSR). RESULTS: Of 2,460 abstracts, 52 met review eligibility criteria (aggregate population 171,558,651). Mean hydrocephalus prevalence was 85/100,000 [95% CI 62, 116]. The prevalence was 88/100,000 [95% CI 72, 107] in pediatrics; 11/100,000 [95% CI 5, 25] in adults; and 175/100,000 [95% CI 67, 458] in the elderly. The ICBDSR-based incidence of hydrocephalus diagnosed at birth remained stable over 11 years: 81/100,000 [95% CI 69, 96]. A significantly lower incidence was identified in high-income countries. CONCLUSION: This systematic review established age specific global hydrocephalus prevalence. While high-income countries had a lower hydrocephalus incidence according to the ICBDSR registry, folate fortification status was not associated with incidence. Our findings may inform future healthcare resource allocation and study.

AB - INTRODUCTION: Patient registries play an important role in obtaining real-world evidence of the cost-effectiveness of treatments. However, their implementation is costly and sometimes infeasible in many middle-income countries (MICs). We explored the combination of data-mining and a large claims database to estimate the direct healthcare costs of HER2-positive breast cancer (BC) treatment in Iran and the fraction of total costs from trastuzumab use. METHOD: We performed a retrospective analysis of claims data from the Iran Social Security Organization, a health insurer which covers approximately 50%(~40 million) of the Iranian population, in the period of 21/03/2011-20/03/2014. A data-mining algorithm using R software and validated using patient dossiers in the Cancer Research Center identified 1295 patients and divided them into the three main HER2-positive breast cancer stages (early, loco-regional and advanced). A payer perspective was used to calculate the absolute and relative direct costs of healthcare services associated with the treatment of HER2-positive breast cancer in the public and private healthcare systems. RESULTS: The number of women totaled 802 (early), 125 (loco-regional) and 218 (advanced). The mean age[SD] was 45[10], 46[10] and 48[10] years, respectively, while mean follow-up in all stages was approximately one year. Average costs of direct healthcare care in early, loco-regional and advanced stages were ?11,796 (95%CI: ?9,356-?12,498), ?8,253 (95%CI: ?6,843 ?10,002), and ?17,742 (95%CI: ?15,720-?19,505), respectively. Trastuzumab accounted for the largest share of total costs in all three stages (range: 53 76%). CONCLUSION: Wherever comprehensive patient registries are infeasible or costly, real-world costs can be estimated through claims databases and data mining strategies. Using this method, real-world costs have been estimated in Iran. The stage-specific cost estimates derived from this study can be used to perform real-world cost-effectiveness analyses of therapies for HER2-positive BC and support healthcare financing decisions.

AB - Neutrophils are the first infiltrating cell type essential for combating pneumoseptic infections by bacterial pathogens including Klebsiella pneumoniae (KPn). Following an infection or injury, removal of apoptotic infiltrates via a highly regulated process called efferocytosis is required for restoration of homeostasis, but little is known regarding the effect of bacterial infection on this process. Here we demonstrate that KPn infection impedes the efferocytic uptake of neutrophils in-vitro and in-vivo in lungs by macrophages. This impaired efferocytosis of infected neutrophils coincides with drastic reduction in the neutrophil surface exposure of apoptosis signature phospholipid phosphatidyserine (PS); and increased activity of phospholipid transporter flippases, which maintain PS in the inner leaflet of plasma membrane. Concomitantly, pharmacological inhibition of flippase activity enhanced PS externalization and restored the efferocytosis of KPn infected neutrophils. We further show that KPn infection interferes with apoptosis activation and instead activates non apoptotic programmed cell death via activation of necroptosis machinery in neutrophils. Accordingly, pharmacological inhibition of necroptosis by RIPK1 and RIPK3 inhibitors restored the efferocytic uptake of KPn infected neutrophils in vitro. Importantly, treatment of KPn infected mice with necroptosis inhibitor improved the disease outcome in-vivo in preclinical mouse model of KPn pneumonia. To our knowledge, this is the first report of neutrophil efferocytosis impairment by KPn via modulation of cell death pathway, which may provide novel targets for therapeutic intervention of this infection.

AB - Necrotizing enterocolitis (NEC) remains the leading cause of gastrointestinal morbidity and mortality in premature infants. Human and animal studies suggest a role for Paneth cells in NEC pathogenesis. Paneth cells play critical roles in host-microbial interactions and epithelial homeostasis. The ramifications of eliminating Paneth cell function on the immature host-microbial axis remains incomplete. Paneth cell function was depleted in the immature murine intestine using chemical and genetic models, which resulted in intestinal injury consistent with NEC. Paneth cell depletion was confirmed using histology, electron microscopy, flow cytometry, and real time RT-PCR. Cecal samples were analyzed at various time points to determine the effects of Paneth cell depletion with and without Klebsiella gavage on the microbiome. Deficient Paneth cell function induced significant compositional changes in the cecal microbiome with a significant increase in Enterobacteriacae species. Further, the bloom of Enterobacteriaceae species that occurs is phenotypically similar to what is seen in human NEC. This further strengthens our understanding of the importance of Paneth cells to intestinal homeostasis in the immature intestine. PMID- 30273396 TI - Fibroblast growth factor 2 is necessary for the antidepressant effects of fluoxetine. AB - Previous research has shown that fibroblast growth factor 2 protein (FGF2) can act as an anxiolytic and anti-depressive agent in rodents. Levels of hippocampal FGF2 and FGF2 receptors are decreased in post-mortem brains of individuals with mood disorders. No changes in FGF2 were noted in the post-mortem brains of individuals with mood disorders that were successfully treated with anti depressant medication prior to death. Mutations in the FGF2 gene in humans have been shown to predict non-responsiveness to the therapeutic effects of selective serotonin reuptake inhibitors (SSRIs). These findings suggest that FGF2 may potentially be a target of and/or required for the therapeutic effects of antidepressant medications. To test this, we employed a rodent model of depressive behaviour, chronic variable stress (CVS) in conjunction with antidepressant treatment (fluoxetine) in wild-type (WT) and FGF2 knockout mice (FGF2KO) and examined depressive and anxiety behaviors. Results showed that fluoxetine reversed the effects of CVS on depressive and anxiety behaviours in wild-type mice only, suggesting that the FGF2 gene is indeed necessary for the therapeutic effects of fluoxetine. Interestingly, CVS decreased hippocampal FGF2 levels and fluoxetine partially reversed this effect. Because FGF2 has been previously shown to modify HPA activity through hippocampal glucocorticoid receptors (GR), we examined levels of glucocorticoid receptors and found a decrease in GR in response to CVS, with a further decrease in FGF2KO. No effect of fluoxetine on GR was observed in either WT or FGF2KO mice. This suggests that further changes in glucocorticoid receptors are not necessary for the anti depressant effects of fluoxetine in WT mice, although decreased glucocorticoid receptors in response to FGF2 deletion may preclude the therapeutic actions of fluoxetine in FGF2KO. Whether astroglia, astroglial functions, or HPA changes are the downstream target of FGF2-mediated changes induced by fluoxetine remains to be determined, however, the current study reaffirms the potential of FGF2 as a novel therapeutic target in the treatment of depression and anxiety disorders. PMID- 30273397 TI - Ziziphus spina-christi leaf extract ameliorates schistosomiasis liver granuloma, fibrosis, and oxidative stress through downregulation of fibrinogenic signaling in mice. AB - Schistosomiasis is a widespread parasitic infection that affects humans, as well as wild and domestic animals. It ranks second after malaria, with a significant health and socio-economic impact in the developing countries. The objective of this study was to assess the anti-schistosomal impact of Ziziphus spina-christi leaf extract (ZLE) on Schistosoma mansoni-induced liver fibrosis in CD-1 Swiss male albino mice. S. mansoni infection was achieved by dipping of mouse tails in schistosomal cercariae. ZLE treatment was initiated at 46 days post-infection by administering a dose of the extract on a daily basis for 10 consecutive days. S. mansoni infection resulted in liver granuloma and fibrosis, with a drastic elevation in liver function factors, nitric oxide, and lipid peroxidation, which were associated with a reduction in glutathione content and substantial inhibition of antioxidant enzyme activities compared to those of the control. Induction of hepatic granuloma, oxidative stress, and fibrosis in the liver was controlled by ZLE administration, which also produced inhibition of matrix metalloproteinase-9, alpha-smooth muscle actin, transforming growth factor-beta, and tissue inhibitors of metalloproteinases expressions. In addition, the S. mansoni-infected group exhibited an increase in Bax and caspase-3 levels and a decrease in Bcl-2 level. However, treatment with ZLE mainly mitigated apoptosis in the liver. Thus, the findings of this study revealed that Ziziphus spina christi had anti-apoptotic, anti-fibrotic, antioxidant, and protective effects on S. mansoni-induced liver wounds. The benefits of Ziziphus spina-christi extract on S. mansoni were partly partially mediated by enhancing anti-fibrinogenic and nuclear factor erythroid 2-related factor 2 (Nrf2) pathways. PMID- 30273398 TI - Body mass index may predict the response to ipilimumab in metastatic melanoma: An observational multi-centre study. AB - INTRODUCTION: Immunotherapy is a well-established treatment option in patients with metastatic melanoma. However, biomarkers that can be used to predict a response in these patients have not yet been found, putting patients at risk of severe side effects. METHODS: In this retrospective analysis, we investigated the association between the body mass index and ipilimumab treatment response in patients with metastatic melanoma. Patients with metastatic melanoma who received a monotherapy of up to 4 doses of ipilimumab (3 mg/kg) every 3 weeks from 2011 to 2014 in three major hospitals in Austria were included. Patients were classified into two groups: normal group (BMI<25) and overweight group (BMI>=25). RESULTS: 40 patients had a normal BMI, and 36 had a BMI above normal. Patients with a BMI that was above normal showed significantly higher response rates (p = 0.024, chi2), and lower likelihood of brain metastases (p = 0.012, chi2). No differences were found between both groups with respect to gender (p = 0.324, chi2), T-stage (p = 0.197, chi2), or the occurrence of side effects (p = 0.646, chi2). Patients with a BMI above normal showed a trend towards longer overall survival (p = 0.056, Log-Rank), but no difference was found regarding progression-free survival (p = 0.924, Log-Rank). CONCLUSIONS: The BMI correlated with the response to ipilimumab treatment in a cohort of metastatic melanoma patients. PMID- 30273399 TI - Pathological alleles of MPV17 modeled in the yeast Saccharomyces cerevisiae orthologous gene SYM1 reveal their inability to take part in a high molecular weight complex. AB - Mitochondrial DNA depletion syndromes (MDDS) are a genetically and clinically heterogeneous group of human diseases caused by mutations in nuclear genes and characterized by a severe reduction in mitochondrial DNA (mtDNA) copy number leading to impaired energy production in affected tissues and organs. Mutations in the MPV17 gene, whose role is still elusive, were described as cause of the hepatocerebral form of MDDS and Navajo neuro-hepathopathy. The high degree of conservation observed between MPV17 and its yeast homolog SYM1 made the latter a good model for the study of the pathology. Here, we used Saccharomyces cerevisiae to elucidate the molecular consequences of seven MPV17 missense mutations identified in patients and localized in different protein domains. The phenotypic analysis of the appropriate sym1 mutant strains created demonstrated deleterious effect for all mutations regarding OXPHOS metabolism and mtDNA stability. We deepened the pathogenic effect of the mutations by investigating whether they prevented the correct protein localization into the mitochondria or affected the stability of the proteins. All the Sym1 mutant proteins correctly localized into the mitochondria and only one mutation predominantly affects protein stability. All the other mutations compromised the formation of the high molecular weight complex of unknown composition, previously identified both in yeast, cell cultures and mouse tissues, as demonstrated by the consistent fraction of the Sym1 mutant proteins found free or in not fully assembled complex, strengthening its role as protein forming part of a high molecular weight complex. PMID- 30273400 TI - Childhood socioeconomic position and physical capability in late-middle age in two birth cohorts from the Copenhagen aging and midlife biobank. AB - This study examines the association between childhood socioeconomic position and objective physical capability including new functional measures of potential relevance to a population in late-middle age. The study population covers two Danish birth cohorts followed-up in the Copenhagen Aging and Midlife Biobank (age 48-58 years, 2009-2011, N = 4,204). Results from linear regression models revealed that being born in higher socioeconomic position was associated with higher jump height: Paternal occupational class four = 0.19 cm (95% confidence interval (CI): -0.44, 0.82), three = 0.59 cm (95% CI: -0.02, 1.19), two = 1.29 cm (95% CI: 0.64, 1.94), and one = 1.29 cm (95% CI: 0.45, 2.13) (reference = five); medium parental social class = 0.88 cm (95% CI: 0.03, 1.72) and high = 1.79 cm (95% CI: 0.94, 2.63) (reference = low). Higher childhood socioeconomic position was also associated with better chair rise performance and hand grip strength, while among women it was related to reduced flexibility: Medium parental social class = -1.31 cm (95% CI: -3.05, 0.42) and high = -2.20 cm (95% CI: -3.94, -0.47) (reference = low); unwed mother = 1.75 cm (95% CI: 0.36, 3.14) (reference = married). Overall, the findings suggest that higher childhood socioeconomic position is primarily related to moderately better scores in the most strenuous physical capability measures and hand grip strength among healthy adults in late middle age. PMID- 30273401 TI - Inflammatory cytokine oncostatin M induces endothelial activation in macro- and microvascular endothelial cells and in APOE*3Leiden.CETP mice. AB - AIMS: Endothelial activation is involved in many chronic inflammatory diseases, such as atherosclerosis, and is often initiated by cytokines. Oncostatin M (OSM) is a relatively unknown cytokine that has been suggested to play a role in both endothelial activation and atherosclerosis. We comprehensively investigated the effect of OSM on endothelial cell activation from different vascular beds and in APOE*3Leiden.CETP mice. METHODS AND RESULTS: Human umbilical vein endothelial cells, human aortic endothelial cells and human microvascular endothelial cells cultured in the presence of OSM express elevated MCP-1, IL-6 and ICAM-1 mRNA levels. Human umbilical vein endothelial cells and human aortic endothelial cells additionally expressed increased VCAM-1 and E-selectin mRNA levels. Moreover, ICAM-1 membrane expression is increased as well as MCP-1, IL-6 and E-selectin protein release. A marked increase was observed in STAT1 and STAT3 phosphorylation indicating that the JAK/STAT pathway is involved in OSM signaling. OSM signals through the LIF receptor alfa (LIFR) and the OSM receptor (OSMR). siRNA knockdown of the LIFR and the OSMR revealed that simultaneous knockdown is necessary to significantly reduce MCP-1 and IL-6 secretion, VCAM-1 and E-selectin shedding and STAT1 and STAT3 phosphorylation after OSM stimulation. Moreover, OSM administration to APOE*3Leiden.CETP mice enhances plasma E-selectin levels and increases ICAM-1 expression and monocyte adhesion in the aortic root area. Furthermore, Il-6 mRNA expression was elevated in the aorta of OSM treated mice. CONCLUSION: OSM induces endothelial activation in vitro in endothelial cells from different vascular beds through activation of the JAK/STAT cascade and in vivo in APOE*3Leiden.CETP mice. Since endothelial activation is an initial step in atherosclerosis development, OSM may play a role in the initiation of atherosclerotic lesion formation. PMID- 30273402 TI - Indoor residual spraying for kala-azar vector control in Bangladesh: A continuing challenge. AB - BACKGROUND: Visceral leishmaniasis (VL) in the Indian subcontinent is a fatal disease if left untreated. Between 1994 to 2013, the Ministry of Health of Bangladesh reported 1,09,266 cases of VL and 329 VL related deaths in 37 endemic districts. Indoor residual spraying (IRS) using dichlorodiphenyltrichloroethane (DDT) was used by the national programme in the 1960s to control malaria. Despite findings of research trials demonstrating that the synthetic pyrethroid deltamethrin 5 WP was very effective at reducing vector densities, no national VL vector control operations took place in Bangladesh between 1999 to early 2012. In 2012, IRS using deltamethrin 5 WP was re-introduced by the national programme, which consisted of pre-monsoon spraying in eight highly endemic sub-districts (upazilas). The present study aims to evaluate the effectiveness of IRS on VL vectors, as well as the process and performance of the spraying activities by national programme staff. METHODS: Five highly endemic upazilas of Mymensingh district were purposively selected (Fulbaria, Trishal, Mukthagacha, Gaforgaon and Bhaluka) to conduct the present study using the WHO/TDR monitoring and evaluation tool kit. IRS operations, conducted by 136 squads/teams, and 544 spraymen, were observed using check lists and questionnaires included in the WHO/TDR monitoring and evaluation tool kit. A household (HH) acceptability survey of IRS was conducted in all study areas using a structured questionnaire in 600 HHs. To measure the efficacy of IRS, pre-IRS (two weeks prior) and post-IRS (at one and five months after), vector density was measured using CDC light traps for two consecutive nights. Bioassays, using the WHO cone-method, were carried out in 80 HHs (40 sprayed and 40 unsprayed) to measure the effectiveness of the insecticide on sprayed surfaces. RESULTS: Of the 544 spraymen interviewed pre-IRS, 60%, 3% and 37% had received training for one, two and three days respectively. During spraying activities, 64% of the spraying squads had a supervisor in 4 upazilas but only one upazila (Mukthagacha) achieved 100% supervision of squads. Overall, 72.8% of the spraying squads in the study upazilas had informed HHs members to prepare their houses prior to spraying. The required personal protective equipment was not provided by the national programme during our observations and the spraying techniques used by all sprayers were sub-standard compared to the standard procedure mentioned in the M&E toolkit. In the HH interviews, 94.8% of the 600 respondents said that all their living rooms and cattle sheds had been sprayed. Regarding the effectiveness measurements (i.e. reduction of vector densities), a total of 4132 sand flies were trapped in three intervals, of which 3310 (80.1%) were P. argentipes; 46.5% (1540) males and 53.5% (1770) females. At one month post-IRS, P. argentipes densities were reduced by 22.5% but the 5 months post-IRS reduction was only 6.4% for both male and female. The bioassay tests showed a mean corrected mortality of P. argentipes sand flies at one month post-IRS of 87.3% which dropped to 74.5% at 4 months post-IRS in three upazilas, which is below the WHO threshold level (80%). CONCLUSION: The national programme should conduct monitoring and evaluation activities to ensure high quality of IRS operations as a pre-condition for achieving a fast and sustained reduction in vector densities. This will continue to be important during the maintenance phase of VL elimination on the Indian subcontinent. Further research is needed to determine other suitable vector control option(s) when the case numbers are very low. PMID- 30273403 TI - Workload implications for clinic workflow with implementation of three dimensional printed customized bolus for radiation therapy: A pilot study. AB - Bolus is commonly used in radiation therapy to improve radiation dose distribution to the target volume, but commercially available products do not always conform well to the patient surface. Tumor control may be compromised, particularly for superficial tumors, if bolus does not conform well and air gaps exist between the patient surface and the bolus. Three-dimensional (3D) printing technology allows the creation of highly detailed, variable shaped objects, making it an attractive and affordable option for customized, patient-specific bolus creation. The use of 3D printing in the clinical setting remains limited. Therefore, the objective of this study was to assess the implications on time and clinical fit using a workflow for 3D printing of customized bolus in companion animals with spontaneous tumors treated with radiation therapy. The primary aim of this study was to evaluate the time required to create a clinical 3D printed bolus. The secondary aims were to evaluate the clinical fit of the bolus and to verify the skin surface dose. Time to segmentation and 3D printing were documented, while the clinical fit of the bolus was assessed in comparison to the bolus created in the treatment planner. The mean and median time from segmentation to generation of 3D printed boluses was 6.15 h and 5.25 h, respectively. The 3D printed bolus was significantly less deviated from the planned bolus compared to the conventional bolus (p = 0.0078) with measured dose under the bolus within 5% agreement of expected dose in 88% of the measurements. Clinically acceptable 3D printed customized bolus was successfully created for treatment within one working day. The most significant impact on time is the 3D printing itself, which therefore has minimal implications on personnel and staffing. Quality assurance steps are recommended when implementing a 3D printing workflow to the radiotherapy clinic. PMID- 30273404 TI - Blaunet: An R-based graphical user interface package to analyze Blau space. AB - McPherson's Blau space and affiliation ecology model is a powerful tool for analyzing the ecological competition among social entities, such as organizations, along a combination of sociodemographic characteristics of their members. In this paper we introduce the R-based Graphical User Interface (GUI) package Blaunet, an integrated set of tools to calculate, visualize, and analyze the statuses of individuals and social entities in Blau space, parameterized by multiple sociodemographic traits as dimensions. The package is able to calculate the Blau statuses at the nodal, dyadic, and meso levels based on three types of information: sociodemographic characteristics, group affiliations (e.g., membership in groups/organizations), and network ties. To facilitate this, Blaunet has the following five main capabilities, it can: 1) identify a list of possible salient dimensions; 2) calculate, plot, and analyze niches for social entities by measuring the social distance along the salient dimensions between individuals affiliated with them; 3) generate Blau bubbles for individuals, thereby allowing the study of interpersonal influence of similar others even with limited or no network information; 4) capture niche dynamics cross-sectionally by calculating the intensity of exploitation from the carrying capacity and the membership rate; and 5) analyze the niche movement longitudinally by estimating the predicted niche movement equations. We illustrate these capabilities of Blaunet with example datasets. PMID- 30273405 TI - Comparison of the modified unbounded penalty and the LASSO to select predictive genes of response to chemotherapy in breast cancer. AB - Covariate selection is a fundamental step when building sparse prediction models in order to avoid overfitting and to gain a better interpretation of the classifier without losing its predictive accuracy. In practice the LASSO regression of Tibshirani, which penalizes the likelihood of the model by the L1 norm of the regression coefficients, has become the gold-standard to reach these objectives. Recently Lee and Oh developed a novel random-effect covariate selection method called the modified unbounded penalty (MUB) regression, whose penalization function can equal minus infinity at 0 in order to produce very sparse models. We sought to compare the predictive accuracy and the number of covariates selected by these two methods in several high-dimensional datasets, consisting in genes expressions measured to predict response to chemotherapy in breast cancer patients. These comparisons were performed by building the Receiver Operating Characteristics (ROC) curves of the classifiers obtained with the selected genes and by comparing their area under the ROC curve (AUC) corrected for optimism using several variants of bootstrap internal validation and cross validation. We found consistently in all datasets that the MUB penalization selected a remarkably smaller number of covariates than the LASSO while offering a similar-and encouraging-predictive accuracy. The models selected by the MUB were actually nested in the ones obtained with the LASSO. Similar findings were observed when comparing these results to those obtained in their first publication by other authors or when using the area under the Precision-Recall curve (AUCPR) as another measure of predictive performance. In conclusion, the MUB penalization seems therefore to be one of the best options when sparsity is required in high-dimension. Further investigation in other datasets is however required to validate these findings. PMID- 30273406 TI - Impact of maternal western diet-induced obesity on offspring mortality and peripheral endocannabinoid system in mice. AB - Over two-thirds of adults in the United States are obese or overweight, which is largely due to chronic overconsumption of diets high in fats and sugars (i.e., Western diet). Recent studies reveal that maternal obesity may predispose offspring to development of obesity and other metabolic diseases; however, the molecular underpinnings of these outcomes are largely unknown. The endocannabinoid system is an important signaling pathway that controls feeding behavior and energy homeostasis, and its activity becomes upregulated in the upper small intestinal epithelium of Western diet-induced obese mice, which drives overeating. In the current investigation, we examined the impact of chronic maternal consumption of Western diet on the expression and function of the endocannabinoid system in several peripheral organs important for food intake and energy homeostasis in offspring. Female C57BL/6Tac mice were fed a Western diet or low-fat/no-sucrose control chow for 10 weeks, then males were introduced for mating. Dams were maintained on their respective diets through weaning of pups, at which time pups were maintained on low-fat/no-sucrose chow for 10 weeks. Neonates born from dams fed Western diet, when compared to those born from mice fed control chow, unexpectedly displayed increases in mortality that occurred exclusively within six days following birth (greater than 50% mortality). Males comprised a larger fraction of surviving offspring from obese dams. Furthermore, surviving offspring displayed transient increases in body mass for first two days post weaning, and no marked changes in feeding patterns and endocannabinoid levels in upper small intestinal epithelium, pancreas, and plasma, or in expression of key endocannabinoid system genes in the upper small intestinal epithelium and pancreas at 10 weeks post-weaning. Collectively, these results suggest that maternal diet composition greatly influences survival of neonate C57BL/6Tac mice, and that surviving offspring from dams chronically fed a Western diet do not display marked changes in body mass, eating patterns, or expression and function of the endocannabinoid system in several peripheral organs important for feeding behavior and energy homeostasis. PMID- 30273407 TI - Noninvasive intracranial pressure assessment using otoacoustic emissions: An application in glaucoma. AB - The theory that glaucoma patients have a lower intracranial pressure (ICP) than healthy subjects is a controversial one. The aim of this study was to assess ICP noninvasively by determining the relationship between distortion product otoacoustic emission (DPOAE) phase and body position and to compare this relationship between patients with primary open angle glaucoma (POAG), patients with normal tension glaucoma (NTG), and controls. The relationship was also calibrated using published data regarding invasive measurements of ICP versus body position. DPOAEs were measured in 30 controls and 32 glaucoma patients (17 POAG, 15 NTG) at the following body positions (assuming 90 degrees as upright): 45, 30, 20, 10, 0 (supine), -10, and -20 degrees . DPOAE phase had a clear, nonlinear relationship with body position. The mean DPOAE phase shifts between the two most extreme body positions (45 to -20 degrees ) were 73.6, 80.7, and 66.3 degrees for healthy, POAG, and NTG, respectively (P = 0.73), and the groups showed the same, nonlinear behaviour. This indicates that there is no evidence that glaucoma patients have a reduced ICP. When calibrated with invasive data, ICP and DPOAE phase were linearly related over an ICP of 3 mmHg. This suggests that, more broadly, DPOAEs could be used in the future to monitor changes in ICP in a clinical setting and to measure dynamic changes in ICP such as diurnal fluctuations or changes induced by certain medications. PMID- 30273408 TI - A bispecific immunotweezer prevents soluble PrP oligomers and abolishes prion toxicity. AB - Antibodies to the prion protein, PrP, represent a promising therapeutic approach against prion diseases but the neurotoxicity of certain anti-PrP antibodies has caused concern. Here we describe scPOM-bi, a bispecific antibody designed to function as a molecular prion tweezer. scPOM-bi combines the complementarity determining regions of the neurotoxic antibody POM1 and the neuroprotective POM2, which bind the globular domain (GD) and flexible tail (FT) respectively. We found that scPOM-bi confers protection to prion-infected organotypic cerebellar slices even when prion pathology is already conspicuous. Moreover, scPOM-bi prevents the formation of soluble oligomers that correlate with neurotoxic PrP species. Simultaneous targeting of both GD and FT was more effective than concomitant treatment with the individual molecules or targeting the tail alone, possibly by preventing the GD from entering a toxic-prone state. We conclude that simultaneous binding of the GD and flexible tail of PrP results in strong protection from prion neurotoxicity and may represent a promising strategy for anti-prion immunotherapy. PMID- 30273409 TI - Hatha yoga for acute, chronic and/or treatment-resistant mood and anxiety disorders: A systematic review and meta-analysis. AB - BACKGROUND: The aim of this study was to systematically investigate the effectiveness of hatha yoga in treating acute, chronic and/or treatment-resistant mood and anxiety disorders. METHODS: Medline, Cochrane Library, Current Controlled Trials, Clinical Trials.gov, NHR Centre for Reviews and Dissemination, PsycINFO and CINAHL were searched through June 2018. Randomized controlled trials with patients with mood and anxiety disorders were included. Main outcomes were continuous measures of severity of mood and anxiety symptoms. Cohen's d was calculated as a measure of effect size. Meta-analyses using a random effects model was applied to estimate direct comparisons between yoga and control conditions for depression and anxiety outcomes. Publication bias was visually inspected using funnel plots. RESULTS: Eighteen studies were found, fourteen in acute patients and four in chronic patients. Most studies were of low quality. For depression outcomes, hatha yoga did not show a significant effect when compared to treatment as usual, an overall effect size of Cohen's d -0.64 (95% CI = -1.41, 0.13) or to all active control groups, Cohen's d -0.13 (95% CI = -0.49, 0.22). A sub-analysis showed that yoga had a significant effect on the reduction of depression compared to psychoeducation control groups, Cohen's d -0.52 (95% CI = -0.96, -0.08) but not to other active control groups, Cohen's d 0.28 (95% CI = 0.07, 0.63) For studies using a follow-up of six months or more, hatha yoga had no effect on the reduction of depression compared to active control groups, Cohen's d -0.14 (95% CI = -0.60, 0.33). Regarding anxiety, hatha yoga had no significant effect when compared to active control groups, Cohen's d -0.09 (95% CI = -0.47, 0.30). The I2 and Q-statistic revealed heterogeneity amongst comparisons. Qualitative analyses suggest some promise of hatha yoga for chronic populations. CONCLUSIONS: The ability to draw firm conclusions is limited by the notable heterogeneity and low quality of most of the included studies. With this caveat in mind, the results of the current meta-analysis suggest that hatha yoga does not have effects on acute, chronic and/or treatment-resistant mood and anxiety disorders compared to treatment as usual or active control groups. However, when compared to psychoeducation, hatha yoga showed more reductions in depression. It is clear that more high-quality studies are needed to advance the field. PMID- 30273411 TI - Is early silcrete heat treatment a new behavioural proxy in the Middle Stone Age? AB - The South African Middle Stone Age (MSA) has in recent years become increasingly important for our understanding of the emergence of 'modern human behaviours'. Several key innovations appeared in this context for the first time, significantly pre-dating their re-invention in the European Upper Palaeolithic. One of these innovations was heat treatment of stone to improve its quality for the production of stone tools. Heat treatment may even be the oldest well documented technique used to intentionally alter the properties of materials in general. It is commonly thought of as requiring the skilled use of fire, a high degree of planning depth and complex cognitive abilities. However, to work on these fundamental concepts we need to analyse the techniques and procedures used to heat-treat and we need to understand what they imply. In this paper, we present a direct and expedient comparison between the technical complexities of four alternative heat treatment procedures by coding the behaviours required for their set-up in so-called cognigrams, a relatively new method for understanding complexity based on the problem-solution distance. Our results show that although the techniques significantly differ in complexity, the techniques used in the MSA fall within the range of complexities known from other MSA techniques. Heat treatment in above-ground fires, as it was practised during this period in South Africa, was even one of the most complex techniques at the time of its invention. Early heat treatment can therefore be considered an important behavioural proxy that may shed light on the behaviour and socioeconomic structure of past groups. The implications of this are highlighted by the ongoing debate about 'modernity', 'behavioural flexibility' and 'complex cognition' of early anatomically modern humans in Africa. PMID- 30273410 TI - What are the perceptions about running and knee joint health among the public and healthcare practitioners in Canada? AB - OBJECTIVES: To evaluate the perceptions of the general public and healthcare practitioners (HCP) in Canada about the relationship between running and knee joint health, and to explore HCP's usual recommendations to runners with knee osteoarthritis (KOA). METHODS: Non-runners and runners (with and without KOA) and HCP completed an online survey regarding the safety of running for knee joint health. HCP also provided information related to usual clinical recommendations. Proportions of agreement were compared between non-runners and runners. RESULTS: A total of 114 non-runners, 388 runners and 329 HCP completed the survey. Overall, running was perceived as detrimental for the knee joint by 13.1% of the general public, while 25.9% were uncertain. More uncertainty was reported regarding frequent (33.9%) and long-distance (43.6%) running. Statistical analyses revealed greater proportions of non-runners perceiving running negatively compared with runners. Overall, 48.4% believed that running in the presence of KOA would lead to disease progression, while 53.1% believed running would lead to premature arthroplasty. In HCP, 8.2%, 9.1% and 22.2% perceived that running in general, running frequently, or running long-distances are risk factors for KOA, respectively. 37.1% and 2.7% of HCP typically recommended patients with KOA to modify their running training or to quit running, respectively. CONCLUSION: High rates of uncertainty among the general public and HCP in Canada outline the need for further studies about running and knee joint health. Filling knowledge gaps will help inform knowledge translation strategies to better orientate the general public and HCP about the safety of running for knee joint health. PMID- 30273412 TI - Effects of breeding center, age and parasite burden on fecal triiodothyronine levels in forest musk deer. AB - The objective of this study was to evaluate the effects of sex, breeding center and age on fecal triiodothyronine levels in captive forest musk deer Moschus berezovskii, and to explore the age-intensity model of gastrointestinal parasites. Furthermore, the association between fecal triiodothyronine levels and parasite egg shedding was also analyzed. We collected musk deer fecal samples from two breeding centers located in Shaanxi and Sichuan province, China. Enzyme linked immunosorbent assays were utilized to estimate the fecal triiodothyronine concentrations and profiles, and fecal parasite eggs or oocysts were counted using the McMaster technique. Female deer from both breeding centers consistently showed higher triiodothyronine concentrations than those observed in males, which indicates that a distinct physiology pattern occurs by sex. The triiodothyronine concentration in Sichuan breeding center was significantly higher than that in Shaanxi center for both sexes, suggesting that differences in environment, diet and management practices are likely to affect the metabolism. In addition, a negative relationship between triiodothyronine concentrations and age was found (r = - 0.75, p < 0.001), and parasite egg shedding was also negatively associated with age (r = - 0.51, p < 0.001), by which we can infer that older animals evolves a more developed immune system. Finally, a positive association between parasite egg shedding and triiodothyronine levels was found, which could be explained by the additional energy metabolism resulting from parasitic infection. Results from this study might suggest metabolic and immunological adaptations in forest musk deer. These baseline data could be used to unveil metabolic status and establish parasite control strategies, which has great potential in captive population management as well as their general health evaluations. PMID- 30273413 TI - Dietary calcium intake and food sources among Chinese adults in CNTCS. AB - BACKGROUND: Calcium is one of the essential micronutrients in the human body and is well-known for its important role in keeping bones and teeth healthy. However, calcium deficiency is a very common nutritional problem in the world and especially in China. The aim of this research was to determine the dietary calcium intake of Chinese adults and the corresponding food sources based on data from the 2015 China Nutritional Transition Cohort Study. METHODS: We obtained dietary data from Chinese adults ages 18 to 64 years in 15 provinces, autonomous regions, and municipalities using 3 consecutive days combined with the household weighing method. We used the China Food Composition (book 1, 2nd edition) to calculate the calcium intake from each food category. We regarded the percentage of participants with a calcium intake median below the estimated average requirement as the level of calcium inadequacy in the overall population. RESULTS: We divided the participants into 2 age groups, 18-49 years and 50-64 years, which included 6,630 and 5,307 participants, respectively. The groups' dietary calcium intake medians were 324.8 milligrams per day (mg/d) and 332.7 mg/d, respectively, and the calcium inadequacies were 92.9% and 96.0%, correspondingly. The median calcium intake for the whole study population was 328.3 mg/d, and the inadequacy was 94.3%, which improved with higher education, income, and urbanization levels. The main food sources of dietary calcium among the study population were vegetables, legumes, and cereals, which contributed 30.2%, 16.7%, and 14.6%, respectively. Milk and dairy products contributed 6.7% to the study population but varied with the urbanization level to 15.0%, 6.1%, 6.3%, and 2.0% in urban, suburban, county, and rural areas, respectively. CONCLUSION: These findings highlight the importance of nutrition education and intervention for Chinese adults to improve their dietary structures and increase milk and dairy products intake to consume adequate calcium. PMID- 30273414 TI - Phylogenetically Novel Uncultured Microbial Cells Dominate Earth Microbiomes. AB - To describe a microbe's physiology, including its metabolism, environmental roles, and growth characteristics, it must be grown in a laboratory culture. Unfortunately, many phylogenetically novel groups have never been cultured, so their physiologies have only been inferred from genomics and environmental characteristics. Although the diversity, or number of different taxonomic groups, of uncultured clades has been studied well, their global abundances, or numbers of cells in any given environment, have not been assessed. We quantified the degree of similarity of 16S rRNA gene sequences from diverse environments in publicly available metagenome and metatranscriptome databases, which we show have far less of the culture bias present in primer-amplified 16S rRNA gene surveys, to those of their nearest cultured relatives. Whether normalized to scaffold read depths or not, the highest abundances of metagenomic 16S rRNA gene sequences belong to phylogenetically novel uncultured groups in seawater, freshwater, terrestrial subsurface, soil, hypersaline environments, marine sediment, hot springs, hydrothermal vents, nonhuman hosts, snow, and bioreactors (22% to 87% uncultured genera to classes and 0% to 64% uncultured phyla). The exceptions were human and human-associated environments, which were dominated by cultured genera (45% to 97%). We estimate that uncultured genera and phyla could comprise 7.3 * 1029 (81%) and 2.2 * 1029 (25%) of microbial cells, respectively. Uncultured phyla were overrepresented in metatranscriptomes relative to metagenomes (46% to 84% of sequences in a given environment), suggesting that they are viable. Therefore, uncultured microbes, often from deeply phylogenetically divergent groups, dominate nonhuman environments on Earth, and their undiscovered physiologies may matter for Earth systems. IMPORTANCE In the past few decades, it has become apparent that most of the microbial diversity on Earth has never been characterized in laboratory cultures. We show that these unknown microbes, sometimes called "microbial dark matter," are numerically dominant in all major environments on Earth, with the exception of the human body, where most of the microbes have been cultured. We also estimate that about one-quarter of the population of microbial cells on Earth belong to phyla with no cultured relatives, suggesting that these never-before-studied organisms may be important for ecosystem functions.

AB - Developmental dysplasia of the hip (DDH) is the most common skeletal developmental disease. However, its genetic architecture is poorly understood. We conduct the largest DDH genome-wide association study to date and replicate our findings in independent cohorts. We find the heritable component of DDH attributable to common genetic variants to be 55% and distributed equally across the autosomal and X-chromosomes. We identify replicating evidence for association between GDF5 promoter variation and DDH (rs143384, effect allele A, odds ratio 1.44, 95% confidence interval 1.34-1.56, P = 3.55 * 10-22). Gene-based analysis implicates GDF5 (P = 9.24 * 10-12), UQCC1 (P = 1.86 * 10- 10), MMP24 (P = 3.18 * 10-9), RETSAT (P = 3.70 * 10- 8) and PDRG1 (P = 1.06 * 10- 7) in DDH susceptibility. We find shared genetic architecture between DDH and hip osteoarthritis, but no predictive power of osteoarthritis polygenic risk score on DDH status, underscoring the complex nature of the two traits. We report a scalable, time-efficient recruitment strategy and establish for the first time to our knowledge a robust DDH genetic association locus at GDF5. PMID- 30273418 TI - Report on the status of women occupying leadership roles in oncology. AB - Background: While the global workforce is approaching gender parity, women occupy a small number of management level positions across most professions, including healthcare. Although the inclusion of women into the membership of many oncology societies has increased, the under-representation of women in leadership roles within international and national oncology societies remains relatively consistent. Moreover, the exact status of women participating as board members or presidents of oncology societies or as speakers at oncology congresses was undocumented to date. Methods: The database used in this analysis was derived from data collection performed by the European Society for Medical Oncology for the years 2015-2016 and data analyses performed using the Statistical Analysis Software V.9.3 and R language for statistical computing V.3.4.0 by Frontier Science Foundation-Hellas. The literature search was performed by the authors. Results: We report the presence of a gender gap within oncology. Results regarding the under-representation of women occupying leadership roles in oncology show female participation as members of the board or presidents of national and international oncology societies and as invited speakers at oncology congresses remains below 50% in the majority of societies included in this analysis. Women in leadership positions of societies was associated with a higher percentage of female invited speakers at these societies' congresses (p=0.006). Conclusion: The full contribution that can be attained from using the potential of women in leadership roles is currently under-realised. Examples of how gender and minority participation in organisations improves outcomes and creativity are provided from science, clinical practice and industry that show outcomes are greatly improved by collective participation of both men and women. Although there are programmes in place in many oncology organisations to improve this disparity, the gender gap is still there. Ongoing discussion may help to create more awareness in the effort to accelerate the advancement of women within oncology. PMID- 30273419 TI - Sizing Up the Uncultured Microbial Majority. AB - Predicting the total number of microbial cells on Earth and exploring the full diversity of life are fundamental research concepts that have undergone paradigm shifts in the genomic era. In this issue, Lloyd and colleagues (K. G. Lloyd, A. D. Steen, J. L. Ladau, J. Yin, and L. Crosby, mSystems 3:e00055-18, https://doi.org/10.1128/mSystems.00055-18, 2018) present results that combine these two concepts by estimating the total diversity of all cells from Earth's environments. Leveraging publicly available amplicon, metagenomic, and metatranscriptomic datasets, they determined that nearly all environments are dominated by uncultured lineages, with the exception of humans and human associated habitats. They define a new concept: phylogenetically diverse noncultured cells (PDNC). Unlike viable but nonculturable cells (VBNC), PDNC are microorganisms for which traditional isolation techniques may never succeed. Lloyd et al. estimate that the majority of microorganisms in Earth's ecosystems may be PDNC and conclude that culture-independent methods combined with innovative culturing techniques may be required to understand the ecology and physiology of these abundant and divergent microorganisms.

PMID- 30273420 TI - Gender-related challenges facing oncologists: the results of the ESMO Women for Oncology Committee survey. AB - Background: Although women account for a growing proportion of the oncology workforce, there is evidence they are under-represented in leadership roles. To gain further insights into this issue and extend understanding of gender challenges, the European Society for Medical Oncology Women for Oncology (W4O) Committee undertook a survey of female and male oncologists in 2016. Design: The 2016 W4O questionnaire included questions on (1) Demographics and professional environment, (2) Gender impact on career development, (3) Challenges for career progression and inappropriate behaviour experienced in the workplace, (4) Barriers for gender parity and (5) The gender gap. Between July and September 2016, the online survey was available to male and female clinical and academic oncology healthcare professionals in the EU and internationally. Results: Responses were analysed from 462 oncologists, of whom 76.7 % were women. Of female respondents, 45.5 % had a managerial or leadership role, compared with 65 % of male respondents (p<0.001). Men were more likely to have leadership roles, even in clinical teams with more women than men. Women respondents were more likely to consider their gender had a major impact on their career than men: 35.9 % vs 20.9 % (p<0.001). The biggest challenge to career progression for women was work and family balance (64.2%). Of female respondents, 14.4 % believed there had been significant or major progress in closing the gender pay gap compared with 39.3 % of men (p<0.001). Of female participants, 37.7 % reported they had encountered unwanted sexual comments by a superior or colleague. Conclusions: New initiatives are needed to address under-representation of women oncologists in leadership roles, including greater and concrete promotion of work-life balance, development and leadership training for women, and more support for flexible working. The fact that over a third of women in the survey had encountered unwanted sexual comments at work is of great concern and must be urgently addressed.

AB - We aim to demonstrate possible autonomic dysfunction based on salivary alpha amylase measurements during and after the vertigo attacks associated with Meniere disease (MD) and benign paroxysmal positional vertigo (BPPV). Patients admitted to the emergency room with a diagnosis of vertigo attacks caused by either MD (n = 15) or BPPV (n = 9) constituted the study groups. The control group (n = 10) consisted of volunteer patients admitted to the emergency department with minor soft-tissue trauma. The first saliva samples were obtained immediately during the attacks and the second and third samples were obtained on the third and fifteenth days of the attack, respectively. In the controls, the first sample was obtained after admission to the hospital and the second sample was obtained on the third day. Salivary alpha-amylase levels were evaluated. The difference between salivary alpha-amylase levels in patients with MD and BPPV was not significant. The amylase value measured early after the BPPV attack was significantly lower than that of the controls (p = 0.008). Although not significant, an undulating pattern of salivary alpha-amylase levels was observed with both diseases. An autonomic imbalance could be partly demonstrated by salivary alpha-amylase measurement early after the attack in patients with BPPV. Therefore, amylase may be a promising marker that is worth further investigation. PMID- 30273428 TI - Mucocele development after endoscopic sinus surgery for nasal polyposis: A long term analysis. AB - The aim of the present study was to determine the prevalence of long-term mucocele development after functional endoscopic sinus surgery (FESS) for nasal polyposis, to search for a statistical relationship with preoperative variables and to analyze the management of this complication. A retrospective analysis of 153 patients who underwent FESS for nasal polyposis, with a minimum of 7 years of follow-up, was performed. Mucocele diagnosis was based on regular clinical and radiologic evaluation. Univariate and multivariate statistical analysis was performed. The postoperative mucocele rate was 13.1% (20 patients). The mean delay between surgery and mucocele diagnosis was 6.25 years. A high preoperative Lund-Mackay score (>19) was a risk factor for postoperative mucocele (p = 0.04). Asthma and aspirin intolerance did not increase the risk of this complication. Endoscopic marsupialization of mucoceles was successful in 19 patients, with only one recurrent frontal mucocele. One patient required external approaches for two frontal mucoceles. In conclusion, mucocele risk after FESS for nasal polyposis is significant, especially in case of a high preoperative Lund-Mackay score (>19). Long-term clinical follow-up is recommended, imaging being prescribed based on symptoms or abnormal findings on clinical examination. Endoscopic marsupialization is very effective, but frontal mucoceles are more likely to recur. PMID- 30273429 TI - Positivity rates of in vitro inhalant/respiratory and food allergy tests in the northern midwestern United States. AB - Rates of allergy-test positivity vary by country and by regions within countries. Several studies have looked at allergy test results to determine the most common allergens. Many of these studies have been based on surveys or on studies of small numbers of tests. Positivity rates for allergy tests are poorly defined in the northern midwestern region of the United States. We conducted a study to identify the rates of positive allergy tests for both inhalant/respiratory allergens and food allergens in the upper Midwest. We extracted from our laboratory database the results of all test samples sent for one of eight allergen panels that had been analyzed between Sept. 1, 2014, and Sept. 1, 2015. All testing was performed at The Cleveland Clinic with the Phadia ImmunoCAP system. The percentage of positive tests, the distribution of the most frequently positive tests, and the class of in vitro responses were identified. A total of 148,628 test results for 63 different allergens were identified. Of the 125,190 tests for inhalant/respiratory allergens, the most frequently positive were dog dander (24% of tests), cat dander (23%), dust mites (23% for both Dermatophagoides pteronyssinus and Dermatophagoides farinae), and June grass (21%). Of the 23,438 food tests, the most frequently positive test results were for milk (18%), peanut (17%), wheat (16%), and egg white (15%). Most of the results fell into classes 1 through 3, although there was still a notable number of very high responses (class 5 and 6). These findings suggest that there is wide variability in the positivity of in vitro allergy tests and that the likelihood of a positive result in screening panels can be estimated. Evaluating such rates will help identify the most and least common allergens and will help to cost effectively refine allergy screening panels. PMID- 30273430 TI - Acute infectious laryngitis: A case series. AB - Although acute laryngitis is common, it is often managed by primary physicians. Therefore, video images documenting its signs are scarce. This series includes 7 professional voice users who previously had undergone baseline strobovideolaryngscopy (SVL) during routine examinations or during evaluations for other complaints and who returned with acute laryngitis. Sequential SVL showed not only the expected erythema, edema, cough, and dysphonia, but also new masses in 5 of the 7 subjects. All the signs returned to baseline. This series is reported to highlight the reversible structural changes that can be expected in patients with acute laryngitis and the value of conservative management. PMID- 30273431 TI - No difference in disease-free survival after oral cancer resection with close tumor margins in patients with and without postoperative radiotherapy. AB - We conducted a retrospective follow-up study to determine if adjunctive radiotherapy (RT) affected disease-free survival in patients with oral squamous cell carcinoma (SCC) who were found to have close surgical margins after tumor resection. Our study population was made up of 110 patients-72 men and 38 women, aged 30 to 94 years (median: 66) at the time of diagnosis. Their follow-up ranged from 12 days to 5.2 years (median: 3.6 yr). Of this group, 40 patients had free margins, 55 patients had close margins, and 15 had involved margins after surgery. Only 31 of these patients received postoperative RT, including 17 who had close margins. We would expect to find better postoperative local tumor control with combined surgery and RT, but we found no statistically significant difference in disease-free survival between the surgery-plus-RT group and the surgery-only group (p = 0.72). We also found no significant difference in disease free survival between patients with a tumor of the floor of mouth and those with a tumor of the tongue (p = 0.34). In the study population as a whole, the disease free survival rate was 81.0% and the overall survival rate was 78.2%. Our findings support the trend toward a watch-and-wait approach before initiating postoperative RT for patients with close surgical margins. The decision should be carefully discussed between the surgeon, the oncologic radiotherapist, and the patient. PMID- 30273432 TI - Outcomes of reapplication to otolaryngology residency: A prospective cohort study. AB - Although the field of otolaryngology has experienced a decline in the number of applicants to our residency programs, otolaryngology remains a highly competitive field with an extremely strong applicant pool. Many highly qualified candidates cannot obtain a position in our field each year, and many of these candidates choose to reapply the next year. Data are lacking regarding reapplicants' success rate and the best gap year employment and training options for these reapplicants. Reapplicants were studied prospectively via a two-stage survey during the 2014-2015 and 2015-2016 application cycles. Success rates for the overall group were compared to those from published data, and success rates between subgroups were also compared. First-time reapplicants in the study performed extremely well. Their match rate (19/22) was not significantly different from that of traditional otolaryngology applicants (551/619, p = 0.73) and was significantly higher than that of nontraditional applicants not in our cohort (23/62, p < 0.001). No significant difference was found between applicants by employment/training activities, with both researchers (11/12) and surgical interns (8/10, p = 0.57) performing well. Predictors of reapplicant success could not be assessed because only 3 reapplicants in the cohort were unsuccessful. First-time otolaryngology reapplicants remain a highly competitive group of applicants to our field, regardless of employment/training activities undertaken after graduating medical school. PMID- 30273433 TI - The role of meteorologic factors and air pollution on the frequency of pediatric epistaxis. AB - Fluctuations in atmospheric temperature, humidity, and air pollution are associated with the incidence of epistaxis. To date, no study in the literature has evaluated the effect of air pollution and meteorologic conditions on the pediatric population. We aimed to evaluate the effect of meteorologic factors and air pollution on the frequency of epistaxis in children. Children presenting to an outpatient clinical setting at a tertiary care hospital during a 5-year period (July 1, 2009, to June 30, 2014) and diagnosed with epistaxis formed the study population. Daily temperature and humidity parameters and average daily atmospheric water vapor pressure, average daily concentration of particulate matter <10 MUm in diameter, and sulfur dioxide readings were obtained. The distribution of daily parameters was analyzed. Of the 1,559 children with the primary diagnosis of epistaxis, data from 1,330 children were analyzed after excluding patients with coexisting pathologies. Positive correlations were found between the frequency of epistaxis and both the average daily temperature and the difference between the maximum and minimum daily temperature. There was a negative correlation between the epistaxis frequency and the average daily humidity, the difference between the maximum and minimum daily humidity, the average daily concentration of particulate matter, and the sulfur dioxide levels. Our findings suggest that epistaxis in children is related to high temperatures and low humidity. PMID- 30273434 TI - Renal cell carcinoma metastatic to the sinonasal cavity: A review and report of 8 cases. AB - Renal cell carcinoma (RCC) metastatic in the sinonasal cavity is rare. In many cases, it represents the initial presentation of RCC. We conducted a retrospective chart review to report the clinical presentation, imaging, and treatment of RCC metastases in the sinonasal cavity at two tertiary care referral centers. Our population was made up of 8 patients-6 men and 2 women, aged 55 to 86 years (mean: 66.9; median: 63.5)-who had been diagnosed with cancer in the sinonasal cavity. The most common complaints were epistaxis, nasal obstruction, and diplopia. Cancers were located in the ethmoid sinus (n = 3), nasal cavity (n = 2), sphenoid sinus (n = 2), and maxillary sinus (n = 1). Local treatment involved resection and adjuvant radiotherapy in 4 patients, surgery alone in 2 patients, and radiotherapy alone in the other 2. The lesion was embolized before surgery in 4 cases. We also performed a critical review of similar published cases. Our literature review covered 53 cases of RCC metastatic to the sinonasal cavity, including ours. Metastases were the first presentation of RCC in 24 of these cases (45.3%); in our series, the metastases led to the diagnosis of the primary RCC in 3 cases (37.5%). In the 53 reported cases, metastatic resection was performed on 35 patients (66.0%). Survival data were available for 22 of these operated patients, and 17 of them achieved a complete local response. Adjunctive radiotherapy was not associated with a better local response. Overall survival was significantly better in patients who had an isolated metastasis rather than multiple metastases (p = 0.013). There was no difference in overall survival between patients whose metastasis represented the initial presentation of RCC and those whose metastasis did not (p = 0.95). We recommend that sinonasal metastasis be suspected in the event of unilateral nasal bleeding or nasal obstruction in patients diagnosed with RCC. Embolization may prevent abundant bleeding during removal. Surgery may improve the quality of life of these patients while decreasing nasal obstruction and bleeding. PMID- 30273435 TI - Upper aerodigestive tract frostbite from inhalation of automotive nitrous oxide. AB - Nitrous oxide, a cryogenic gas, may be abused as an inhalant for its euphoric properties. If inhaled, nitrous oxide may cause frostbite to the oral cavity and upper aerodigestive tract, with possible airway compromise due to edema. In this article we describe what is, to the best of our knowledge, the first case of intentional inhalation of nitrous oxide from an automotive nitrous oxide canister and discuss the management and mechanism of the patient's injury. PMID- 30273436 TI - Nondisseminated rhinosporidiosis with multisite involvement in the head and neck. AB - Rhinosporidiosis is a communicable disease prevalent in tropical countries that affects one or more mucocutaneous sites such as the nasal cavity, pharynx, skin, bronchus, genitals, and bone, in isolation or together. We report a case of multicentric rhinosporidiosis involving the nasal cavity, oropharynx, larynx, and cheek skin without disseminated disease outside the head and neck. Although the appearance of mucocutaneous lesions in our patient was similar to that of papilloma or neoplasm, the distinct clinicopathologic characteristics of the rhinosporidiosis guided us in managing the case successfully. In our own experience with 11 patients with rhinosporidiosis on whom we operated over the past 5 years, the nasal cavity and pharynx were the most commonly involved sites in the head and neck. Surgical excision of all lesions along with cauterization of the base and long-term dapsone therapy is the current standard of care for multicentric rhinosporidiosis. PMID- 30273437 TI - Audiologic profile in patients with ankylosing spondylitis: A controlled study of 30 patients. AB - Recent studies have identified sensorineural hearing loss as a possible manifestation of ankylosing spondylitis. We conducted a study of 30 patients with ankylosing spondylitis to characterize their audiologic profile and to correlate their disease activity and functional indices with their hearing thresholds. The study group was made up of 18 men and 12 women, aged 25 to 58 years (mean: 46.5), who were diagnosed with ankylosing spondylitis. We compared their findings with a socially and demographically matched group of 30 healthy controls. All 60 participants underwent an audiologic assessment, consisting of pure-tone audiometry, speech audiometry, and tympanometry. We used validated indices to assess disease activity and functional status, and we compiled information on the time of diagnosis and the types of medications used to treat the ankylosing spondylitis. We found that the average of the mean air-conduction thresholds at 0.5, 1, 2, and 4 kHz in the ankylosing spondylitis group was significantly worse than that of the controls (p = 0.004). A statistically significant difference was observed at frequencies greater than 3 kHz (p < 0.05). A subgroup of case patients who used only a tumor necrosis factor-alpha inhibitor exhibited better hearing thresholds than patients who used other drugs (p = 0.01). Differences in functional and disease activity scores between case patients with and without hearing loss were not statistically significant. We found that patients with ankylosing spondylitis did indeed have a greater prevalence of sensorineural hearing loss but that it was not correlated with either disease activity or functional status.

AB - In this article we report the case of a 41-year-old man with bilateral aural fullness and hearing loss. On examination he was found to have bilateral, dehiscent anterior canal walls with herniation of the mandibular condyle. This herniation partially obstructed the canals and contributed to his symptoms. To the best of our knowledge, this is only the third reported case of bilateral spontaneous temporomandibular joint herniation, and only 28 cases of unilateral spontaneous herniation can be found in the English language literature. While it is a rare phenomenon, it should be considered when evaluating a patient with fluctuating ear symptoms. PMID- 30273439 TI - Histoplasmosis of the head and neck in the immunocompetent patient: Report of 2 cases. AB - Histoplasmosis of the head and neck is rarely seen in immunocompetent patients. We report 2 new cases of histoplasmosis of the head and neck in immunocompetent patients, one an 80-year-old man and the other a 57-year-old man. The older man presented with oral cavity histoplasmosis; his symptoms included pain, dysphagia, and ulcerative lesions. The younger man had laryngeal histoplasmosis, which resulted in hoarseness and dyspnea. We discuss the methods of diagnosis and the classic findings in histoplasmosis, including the microscopic appearance of caseating granulomas, the results of periodic acid-Schiff staining and Gomori staining, and antibody detection of histoplasmosis. We also review the treatment options with antifungals, including amphotericin B and the oral conazole drugs. With an accurate diagnosis and proper treatment, both of our patients recovered well and their symptoms resolved. Because their symptoms overlapped with those of other, more common disease processes, an accurate diagnosis of these patients was essential to treating their infection.

AB - The Ras/mitogen-activated protein kinase (MAPK) pathway controls fundamental cellular processes such as proliferation, differentiation, and apoptosis. The dual-specificity phosphatase 6 (DUSP6) regulates cytoplasmic MAPK signaling by dephosphorylating and inactivating extracellular signal-regulated kinase (ERK1/2) MAPK. To determine the role of DUSP6 in the maintenance of intestinal homeostasis, we characterized the intestinal epithelial phenotype of Dusp6 knockout (KO) mice under normal, oncogenic, and proinflammatory conditions. Our results show that loss of Dusp6 increased crypt depth and epithelial cell proliferation without altering colonic architecture. Crypt regeneration capacity was also enhanced, as revealed by ex vivo Dusp6 KO organoid cultures. Additionally, loss of Dusp6 induced goblet cell expansion without affecting enteroendocrine and absorptive cell differentiation. Our data also demonstrate that Dusp6 KO mice were protected from acute dextran sulfate sodium-induced colitis, as opposed to wild-type mice. In addition, Dusp6 gene deletion markedly enhanced tumor load in Apc Min/+ mice. Decreased DUSP6 expression by RNA interference in HT29 colorectal cancer cells enhanced ERK1/2 activation levels and promoted both anchorage-independent growth in soft agar as well as invasion through Matrigel. Finally, DUSP6 mRNA expression in human colorectal tumors was decreased in advanced stage tumors compared with paired normal tissues. These results demonstrate that DUSP6 phosphatase, by controlling ERK1/2 activation, regulates colonic inflammatory responses, and protects the intestinal epithelium against oncogenic stress. PMID- 30273443 TI - Plasma cells: The programming of an antibody-secreting machine. AB - Antibodies are an essential component of our immune system, underpinning the effectiveness of both the primary immune response to microbial pathogens and the protective and long-lived immunity against re-challenge. All antibodies are produced by relatively rare populations of plasmablasts and plasma cells, collectively termed antibody-secreting cells (ASCs). It is now apparent that ASCs are unique in the body in terms of their gene expression program and metabolic pathways that enable these cells to have an extraordinary rate of immunoglobulin gene transcription, translation, assembly and secretion. In this review we will discuss the cellular, metabolic and molecular specialization that allows ASCs to maintain such high rates of antibody production, in some cases for the life of the individual. Throughout the review we will link these exquisite cellular and molecular adaptations to the major regulators of ASC gene expression, in an attempt to define how the ASC phenotype and function is genetically programmed.

AB - BACKGROUND & AIMS: A new real-time tracking radiotherapy (RTRT) system, the SyncTraX FX4 (Shimadzu, Kyoto, Japan), consisting of four X-ray tubes and four ceiling-mounted flat panel detectors (FPDs) combined with a linear accelerator, was installed at Uonuma Kikan Hospital (Niigata, Japan) for the first time worldwide. In addition to RTRT, the SyncTraX FX4 system enables bony structure based patient verification. Here we provide the first report of this system's clinical commissioning for intracranial stereotactic radiotherapy (SRT). MATERIALS & METHODS: A total of five tests were performed for the commissioning: evaluations of (1) the system's image quality; (2) the imaging and treatment coordinate coincidence; and (3) the localization accuracy of cone-beam computed tomography (CBCT) and SyncTraX FX4; (4) the measurement of air kerma; (5) an end to-end test. RESULTS & DISCUSSION: The tests revealed the following. (1) All image quality evaluation items satisfied each acceptable criterion in all FPDs. (2) The maximum offsets among the centers were <=0.40 mm in all combinations of the FPD and X-ray tubes (preset). (3) The isocenter localization discrepancies between CBCT and preset #3 in the SyncTraX FX4 system were 0.29 +/- 0.084 mm for anterior-posterior, -0.19 +/- 0.13 mm for superior-inferior, 0.076 +/- 0.11 mm for left-right, -0.11 +/- 0.066 degrees for rotation, -0.14 +/- 0.064 degrees for pitch, and 0.072+/-0.058 degrees for roll direction. the Pearson's product moment correlation coefficient between the two systems was >0.98 in all directions. (4) The mean air kerma value for preset #3 was 0.11 +/- 0.0002 mGy in predefined settings (80 kV, 200 mA, 50 msec). (5) For 16 combinations of gantry and couch angles, median offset value in all presets was 0.31 mm (range 0.14-0.57 mm). CONCLUSION: Our results demonstrate a competent performance of the SyncTraX FX4 system in terms of the localization accuracy for intracranial SRT.

AB - The X-ray study on a single crystal of the butterfly-like complex [{Pt(C^C*)(MU pz)}2 ] (1), containing a cyclometalated N-heterocyclic carbene ligand as wings (HC^C*=1-(4-(ethoxycarbonyl)phenyl)-3-methyl-1H-imidazol-2-ylidene), showed three molecules in the asymmetric unit with intermetallic separations (A) of 3.2294(4) (1A), 3.2834(4) (1B), and 3.1208(6) (1C). From the reaction of 1 with excess of CHI3 in the air and the sunlight, complex [{Pt(C^C*)(MU-pz)I)}2 ] (2) (dPt-Pt =2.6079(2) A) was obtained as the major product, while [IPt(C^C*)(MU-pz)2 Pt(C^C*)CHI2 ] (3) (dPt-Pt =2.6324(3) A) was obtained as the major product under argon atmosphere in the dark. Experimental and theoretical investigations showed that an easily accessible radical-like mechanism operates under thermal conditions, with dioxygen acting as an efficient radical (R. ) scavenger. The oxidation of a Pt2 (II,II) "butterfly" by CHI3 to give metal-metal bonded Pt2 (III,III) compounds is described now for the first time. PMID- 30273447 TI - Rostro-caudal organization of the human posterior superior temporal sulcus revealed by connectivity profiles. AB - The posterior superior temporal sulcus (pSTS) plays an important role in biological motion perception but is also thought to be essential for speech and facial processing. However, although there are many previous investigations of distinct functional modules within the pSTS, the functional organization of the pSTS in its full functional heterogeneity has not yet been established. Here we applied a connectivity-based parcellation strategy to delineate the human pSTS subregions based on distinct anatomical connectivity profiles and divided it into rostral and caudal subregions using diffusion tensor imaging. Subsequent multimodal connection pattern analyses revealed distinct subregional connectivity profiles. From this we inferred that the two subregions are involved in distinct functional circuits, the language processing loop and the cognition attention network. These results indicate a convergent functional architecture of the pSTS that can be revealed based on different types of connectivity and is reflected in different functions and interactions. In addition, when the subregions were performing their processing in the different functional circuits, we found asymmetry in the bilateral pSTS. Our findings may improve the understanding of the functional organization of the pSTS and provide new insights into its interactions and integration of information at the subregional level. PMID- 30273448 TI - Focal application of accelerated iTBS results in global changes in graph measures. AB - Graph analysis was used to study the effects of accelerated intermittent theta burst stimulation (aiTBS) on the brain's network topology in medication-resistant depressed patients. Anatomical and resting-state functional MRI (rs-fMRI) was recorded at baseline and after sham and verum stimulation. Depression severity was assessed using the Hamilton Depression Rating Scale (HDRS). Using various graph measures, the different effects of sham and verum aiTBS were calculated. It was also investigated whether changes in graph measures were correlated to clinical responses. Furthermore, by correlating baseline graph measures with the changes in HDRS in terms of percentage, the potential of graph measures as biomarker was studied. Although no differences were observed between the effects of verum and sham stimulation on whole-brain graph measures and changes in graph measures did not correlate with clinical response, the baseline values of clustering coefficient and global efficiency showed to be predictive of the clinical response to verum aiTBS. Nodal effects were found throughout the whole brain. The distribution of these effects could not be linked to the strength of the functional connectivity between the stimulation site and the node. This study showed that the effects of aiTBS on graph measures distribute beyond the actual stimulation site. However, additional research into the complex interactions between different areas in the brain is necessary to understand the effects of aiTBS in more detail.

AB - Eye-tracking studies have demonstrated that individuals with autism spectrum disorder sometimes show differences in attention and gaze patterns. This includes preference for certain nonsocial objects, heightened attention to detail, and more difficulty with attention shifting and disengagement, which may be associated with restricted and repetitive behaviors. This study utilized a visual exploration task and replicates findings of reduced number of objects explored and increased fixation duration on high autism interest objects in a large sample of individuals with autism spectrum disorder (n = 129, age 6-54 years) in comparison with a typically developing group. These findings correlated with parent-reported repetitive behaviors. Additionally, we applied recurrent quantification analysis to enable identification of new eye-tracking features, which accounted for temporal and spatial differences in viewing patterns. These new features were found to discriminate between autism spectrum disorder and typically developing groups and were correlated with parent-reported repetitive behaviors. Original and novel eye-tracking features identified by recurrent quantification analysis differed in their relationships to reported behaviors and were dependent on age. Trial Registration: NCT02299700. Autism Research 2018, 11: 1554-1566. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Using eye-tracking technology and a visual exploration task, we showed that people with autism spectrum disorder (ASD) spend more time looking at particular kinds of objects, like trains and clocks, and look at fewer objects overall than people without ASD. Where people look and the order in which they look at objects were related to the restricted and repetitive behaviors reported by parents. Eye-tracking may be a useful addition to parent reports for measuring changes in behavior in individuals with ASD. PMID- 30273451 TI - Zinc Oxide-Catalyzed Dehydrogenation of Primary Alcohols into Carboxylic Acids. AB - Zinc oxide has been developed as a catalyst for the dehydrogenation of primary alcohols into carboxylic acids and hydrogen gas. The reaction is performed in mesitylene solution in the presence of potassium hydroxide, followed by workup with hydrochloric acid. The transformation can be applied to both benzylic and aliphatic primary alcohols and the catalytically active species was shown to be a homogeneous compound by a hot filtration test. Dialkylzinc and strongly basic zinc salts also catalyze the dehydrogenation with similar results. The mechanism is believed to involve the formation of a zinc alkoxide which degrades into the aldehyde and a zinc hydride. The latter reacts with the alcohol to form hydrogen gas and regenerate the zinc alkoxide. The degradation of a zinc alkoxide into the aldehyde upon heating was confirmed experimentally. The aldehyde can then undergo a Cannizzaro reaction or a Tishchenko reaction, which in the presence of hydroxide leads to the carboxylic acid.

Vacuum-therapy was conducted preoperatively and postoperatively together with autodermoplasty. The injection material for the skin regeneration "lacerta" was applied subcutaneously intraoperatively. The Ialuset-cream bandages were used in 10 - 12 days postoperatively during 2-3 weeks. Efficacy of vacuum-therapy was estimated, basing on analysis of the wound process course dynamics, clinic laboratory criteria, terms of the wound defect complete closure. The patients' stationary treatment duration have constituted 38.3 days at average. Complex treatment of chronic wounds have had guaranteed complete healing of the wound defect in 7 (63%) patients in terms up to 1 - 5 weeks, and in 3 (26%) - 6 weeks. PMID- 30273480 TI - Antibacterial Surface Coating for Bone Scaffolds Based on the Dark Catalytic Effect of Titanium Dioxide. AB - Biomaterials which promote tissue integration and resist microbial colonisation are required in bone tissue engineering to prevent biomaterial-associated infections. Surface modification of established materials for bone tissue engineering, such as TiO2, have emerged as promising anti-infective strategies. Interestingly, the antibacterial activity of TiO2 in the form of particles can be enhanced by combining it with H2O2, even in the absence of irradiation. However, it remains unknown whether TiO2 surfaces elicit a similar effect. In this study, the antibacterial effect of porous TiO2 scaffolds generated by the catalytic decomposition of H2O2 in the absence of light (dark catalysis) was investigated. Porous ceramic foams were fabricated and sol-gel coated for high catalytic activity. Degradation of methylene blue in the presence of 3% H2O2 increased by 80% for the sol-gel-coated surfaces. The degradation kinetics indicate that intermediate free radicals that form at the liquid-TiO2 interface are responsible for the oxidative behavior of the surface. TiO2 surfaces were further pretreated with 30% H2O2 for prolonged oxidative behavior. The biological response toward such surfaces was assessed in vitro. S. epidermidis biofilms formed on modified surfaces showed reduced viability compared to nonmodified surfaces. Further, the same surface modification showed no cytotoxic effects on MC3T3 preosteoblasts. However, the results from the conducted genotoxicity assay were inconclusive, and further studies are needed to exclude ROS-mediated DNA damage. To conclude, this study provides evidence that a simple surface modification based on the dark catalytic effect of TiO2 can be used to create antibacterial surface properties for ceramic bone scaffolds. PMID- 30273479 TI - [THE IMPACT OF XENOTRANSPLANTATION OF NEUROGENIC STEM CELLS IN COMPLEX WITH THE TISSUE MATRIX NEUROGELTM ON THE POSTTRAUMATIC SPASTICITY SYNDROME COURSE IN EXPERIMENT]. AB - The impact of implantation of synthetic matrix NeuroGelTM together with neurogenic stem cells (NSC) on the course of posttraumatic spasticity syndrome was studied. The laboratory animals were white mongrel male rats (5 mo, 250 g); the trauma simulation - transsection of the left half of spinal cord (SC) on the TXI level. Experimental group 1 consisted of a SC trauma, homotopic implantation of NeuroGelTM together with NSC of fetal (E17) mice hippocampus (n=20); while group 2 - a SC trauma, homotopic implantation of NeuroGelTM (n=20); and group 3 - a SC trauma (n=16). Investigation of the function index and the spasticity index of posterior ipsilateral extremity was done in accordance to Basso-Beattie Bresnahan and Ashworth scales. Association of the function index and the spasticity index of posterior ipsilateral extremity in all groups in various variants of the samples formation is ambiguous, witnessing possibility of additional correlation between these characteristics of a movement system. The NSC xenotransplantation in conjunction with NeuroGelTM changes the spasticity syndrome course, creates conditions for its facilitation in remote period after a SC trauma. PMID- 30273481 TI - Superhydrophobic SiC/CNTs Coatings with Photothermal Deicing and Passive Anti Icing Properties. AB - For faster and greener anti-icing/deicing, a new generation of anti-icing materials are expected to possess both passive anti-icing properties and active deicing properties. The photothermal effect of carbon nanotubes (CNTs) is used in the field of photothermal cancer therapy, while the application in anti icing/deicing is seldom investigated. Superhydrophobic SiC/CNTs coatings with photothermal deicing and passive anti-icing properties were first prepared by a simple spray-coating method. The results of 3D profile and microstructure observed via scanning electron microscopy demonstrate that the micronanostructure combined with peaklike SiC microstructure and villiform CNTs nanostructure makes the coatings surface superhydrophobic, exhibiting a water contact angle of up to 161 degrees and a roll angle as low as 2 degrees . This micronanostructure can also reduce ice anchoring and ice adhesion strength. Utilizing the photothermal effect of CNTs, the surface temperature of the coatings is rapidly increased upon near-infrared light (808 nm) irradiation. The heat is transferred rapidly to the surroundings by highly thermal conductive CNTs. The light-to-heat conversion efficiency in deicing tests is approximately 50.94%, achieving a highly efficient remote deicing effect. This superhydrophobic coating combining photothermal deicing and passive anti-icing properties is expected to be further used in various practical applications and in development of a new generation of anti icing/deicing coatings. PMID- 30273483 TI - Building Block Based Construction of Membrane-Organelle Double Targeted Nanosystem for Two-Drug Delivery. AB - Despite the claim that encapsulation of drugs improves the therapeutic profile of free drugs, there are still important limitations in drug delivery. With respect to cancer treatment, two promising implementations are combination therapy and targeted devices, which are aimed at increasing the drug effect either by achieving higher cell death rates or by discriminating between cell populations. However, for the time being, the scope of combining both approaches is unknown. To advance this knowledge, a two-drug-delivery system with dual cell-organelle targeting based on mesoporous silica nanoparticles, which are known to be able to host drugs within their pores, has been designed. In vitro results show a synergistic effect and high efficacy, demonstrating that the combination of dual therapy and targeting could still advance the development of drug-delivery nanodevices against difficult-to-treat cancers. PMID- 30273482 TI - Phosphorylation Alters the Residual Structure and Interactions of the Regulatory L1 Linker Connecting NBD1 to the Membrane-Bound Domain in SUR2B. AB - ATP-sensitive potassium (KATP) channels in vascular smooth muscle are comprised of four pore-forming Kir6.1 subunits and four copies of the sulfonylurea receptor 2B (SUR2B), which acts as a regulator of channel gating. Recent electron cryo microscopy (cryo-EM) structures of the pancreatic KATP channel show a central Kir6.2 pore that is surrounded by the SUR1 subunits. Mutations in the L1 linker connecting the first membrane-spanning domain and the first nucleotide binding domain (NBD1) in SUR2B cause cardiac disease; however, this part of the protein is not resolved in the cryo-EM structures. Phosphorylation of the L1 linker, by protein kinase A, disrupts its interactions with NBD1, which increases the MgATP affinity of NBD1 and KATP channel gating. To elucidate the mode by which the L1 linker regulates KATP channels, we have probed the effects of phosphorylation on its structure and interactions using nuclear magnetic resonance (NMR) spectroscopy and other techniques. We demonstrate that the L1 linker is an intrinsically disordered region of SUR2B but possesses residual secondary and compact structure, both of which are disrupted with phosphorylation. NMR binding studies demonstrate that phosphorylation alters the mode by which the L1 linker interacts with NBD1. The data show that L1 linker residues with the greatest alpha-helical propensity also form the most stable interaction with NBD1, highlighting a hot spot within the L1 linker. This hot spot is the site of disease-causing mutations and is associated with other processes that regulate KATP channel gating. These data provide insights into the mode by which the phospho-regulatory L1 linker regulates KATP channels. PMID- 30273484 TI - Nitrogen and Phosphorus Codoped Porous Carbon Framework as Anode Material for High Rate Lithium-Ion Batteries. AB - Slow kinetics and low specific capacity of graphite anode significantly limit its applications in the rapidly developing lithium-ion battery (LIB) markets. Herein, we report a carbon framework anode with ultrafast rate and cycling stability for LIBs by nitrogen and phosphorus doping. The electrode structure is constructed of a 3D framework built from 2D heteroatom-doped graphene layers via pyrolysis of self-assembled supramolecular aggregates. The synergistic effect from the nanostructured 3D framework and chemical doping (i.e., N- and P-doping) enables fast kinetics in charge storage and transport. A high reversible capacity of 946 mAh g-1 is delivered at a current rate of 0.5 A g-1, and excellent rate capability (e.g., a capacity of 595 mAh g-1 at 10 A g-1) of the electrode is shown. Moreover, a moderate surface area from the 3D porous structure contributes to a relatively high initial Coulombic efficiency of 74%, compared to other graphene-based anode materials. The electrode also demonstrates excellent cycling stability at a current rate of 2 A g-1 for 2000 cycles. The synthetic strategy proposed here is highly efficient and green, which can provide guidance for large scale controllable fabrication of carbon-based anode materials. PMID- 30273485 TI - Fatty Acid-Based Radically Polymerizable Monomers: From Novel Poly(meth)acrylates to Cutting-Edge Properties. AB - The increasing price of barrels of oil, global warming, and other environmental problems favor the use of renewable resources to replace the petroleum-based polymers used in various applications. Recently, fatty acids (FAs) and their derivatives have appeared among the most promising candidates to afford novel and innovative bio-based (co)polymers because of their ready availability, their low toxicity, and their high versatility. However, the current literature mostly focused on FA-based polymers prepared by condensation polymerization or oxypolymerization, while only a few works have been devoted to radical polymerization due to the low reactivity of FAs through radical process. Thus, the aim of this Review is to give an overview of (i) the most common synthetic pathways reported in the literature to provide suitable monomers from FAs and their derivatives for radical polymerization, (ii) the available radical processes to afford FA-based (co)polymers, and (iii) the different applications in which FA-based (co)polymers have been used since the past few years. PMID- 30273486 TI - A Polymer Blend Approach for Creation of Effective Conjugated Polymer Charge Transport Pathways. AB - Understanding the role of the distribution of polymer chain lengths on process structure-property relationships in semiconducting organic electronics has remained elusive due to challenges in synthesizing targeted molecular weights ( Mw) and polydispersity indices. Here, a facile blending approach of various poly(3-hexylthiophene) (P3HT) molecular weights is used to investigate the impact of the distribution of polymer chain lengths on self-assembly into aggregates and associated charge transport properties. Low and high Mw samples were blended to form a highly polydisperse sample which was compared to a similar, medium Mw control. Self-assembly was induced by preprocessing the polymer solution with UV irradiation and subsequent solution aging before deposition via blade-coating. Superior charge carrier (hole) mobilities were observed for the blend and control samples. Furthermore, their solution lifetimes exceeded 14 days. UV-vis spectral analysis suggests that low Mw P3HT lacks the mesoscale crystallinity required for percolative charge transport. In contrast, when the Mw is too high, the polymer rapidly aggregates, leading to paracrystalline disorder and structural inhomogeneity that interrupts charge-transfer pathways. The role of grain boundaries, fibrillar order, and macroscale alignment is characterized via grazing-incidence wide-angle X-ray scattering, atomic force microscopic, and optical microscopic techniques. The results presented here provide additional guidance on the interplay between polymer solubility, self-assembly, network interconnectivity, and charge transport to enable robust polymer ink formulations with reliable and reproducible performance attributes. PMID- 30273487 TI - Protein Family-Specific Models Using Deep Neural Networks and Transfer Learning Improve Virtual Screening and Highlight the Need for More Data. AB - Machine learning has shown enormous potential for computer-aided drug discovery. Here we show how modern convolutional neural networks (CNNs) can be applied to structure-based virtual screening. We have coupled our densely connected CNN (DenseNet) with a transfer learning approach which we use to produce an ensemble of protein family-specific models. We conduct an in-depth empirical study and provide the first guidelines on the minimum requirements for adopting a protein family-specific model. Our method also highlights the need for additional data, even in data-rich protein families. Our approach outperforms recent benchmarks on the DUD-E data set and an independent test set constructed from the ChEMBL database. Using a clustered cross-validation on DUD-E, we achieve an average AUC ROC of 0.92 and a 0.5% ROC enrichment factor of 79. This represents an improvement in early enrichment of over 75% compared to a recent machine learning benchmark. Our results demonstrate that the continued improvements in machine learning architecture for computer vision apply to structure-based virtual screening. PMID- 30273488 TI - Coherences of Bacteriochlorophyll a Uncovered Using 3D-Electronic Spectroscopy. AB - Mapping the multidimensional energy landscape of photosynthetic systems is crucial for understanding their high efficiencies. Multidimensional coherent spectroscopy is well suited to this task but has difficulty distinguishing between vibrational and electronic degrees of freedom. In pigment-protein complexes, energy differences between vibrations within a single electronic manifold are similar to differences between electronic states, leading to ambiguous assignments of spectral features and diverging physical interpretations. An important control experiment is that of the pigment monomer, but previous attempts using multidimensional coherent spectroscopy lacked the sensitivity to capture the relevant spectroscopic signatures. Here we apply a variety of methods to rapidly acquire 3D electronic-vibrational spectra in seconds, leading to a mapping of the vibrational states of Bacteriochlorophyll a (BChl a) in solution. Using this information, we can distinguish features of proteins containing BChl a from the monomer subunit and show that many of the previously reported contentious spectral signatures are vibrations of individual pigments. PMID- 30273489 TI - Image Correlation Spectroscopy with Second Harmonic Generating Nanoparticles in Suspension and in Cells. AB - The absence of photobleaching, blinking, and saturation combined with a high contrast provides unique advantages of higher-harmonic generating nanoparticles over fluorescent probes, allowing for prolonged correlation spectroscopy studies. We apply the coherent intensity fluctuation model to study the mobility of second harmonic generating nanoparticles. A concise protocol is presented for quantifying the diffusion coefficient from a single spectroscopy measurement without the need for separate point-spread-function calibrations. The technique's applicability is illustrated on nominally 56 nm LiNbO3 nanoparticles. We perform label-free raster image correlation spectroscopy imaging in aqueous suspension and spatiotemporal image correlation spectroscopy in A549 human lung carcinoma cells. In good agreement with the expected theoretical result, the measured diffusion coefficient in water at room temperature is (7.5 +/- 0.3) MUm2/s. The diffusion coefficient in the cells is more than 103 times lower and heterogeneous, with an average of (3.7 +/- 1.5) * 10-3 MUm2/s. PMID- 30273490 TI - Interferometric Measurement of Transient Absorption and Refraction Spectra with Dual Frequency Comb. AB - We demonstrate that a dual frequency comb-transient absorption (DFC-TA) technique can be combined with a time-domain interferometric detection to measure both the transient absorption and refraction spectra of molecules in solution. To do this, the pump-probe signal field of DFC-TA is allowed to interfere with a time-delayed local oscillator field in a time domain. We show that this DFC interferometric pump-probe spectroscopy (DFC-IPS) technique has a unique ability to extract the phase and amplitude information on the pump-probe signal using just a single-scan data, while conventional techniques require an independent signal measured without the pump field for the normalization of the pump-probe spectrum. As a proof-of-principle experiment, we here show that the DFC-IPS enables us to simultaneously measure the frequency-resolved (from 650 to 950 nm) transient absorption and refraction signals with an exceptionally broad dynamic range from femtosecond to nanosecond without using a mechanical translational stage for pump probe time-scanning. We anticipate that our DFC-IPS technique with femtosecond time-resolution capability will be useful to investigate photoinduced chemical and biological reactions covering broad dynamic ranges. PMID- 30273491 TI - Tailoring the Tribocorrosion and Antifouling Performance of (Cr, Cu)-GLC Coatings for Marine Application. AB - Doped graphite-like coating (GLC) has aroused great interest as one of the most promising protective materials in marine applications. However, there is a lack of systematic research on the tribocorrosion and antifouling performance of doped GLC coatings in harsh marine environments. Herein, a multifunctional (Cr, Cu)-GLC coating with combined antifouling and tribocorrosion properties was prepared via a magnetron sputtering method. The experimental results indicate that the resultant coatings changed from a dense structure to a loose columnar structure with the increment of Cr and Cu doping amount. At the same time, the hardness of the coating gradually decreases, but the contact angle between coating and seawater gradually increases. The algae adhesion test reveal that the algae density on the surface of the (Cr, Cu)-GLC coating decreases from about 565 to 70/mm2 as the amount of doping increased. However, on the contrary, the friction coefficient of the coating under OCP condition increases from 0.06 to about 0.35. Overall, the mild doped (Cr, Cu)-GLC coating exhibits the best comprehensive properties, combining antifouling and tribocorrosion properties. The corresponded mechanisms are discussed in terms of the coating microstructure, antifouling, and tribocorrosion behavior. PMID- 30273492 TI - Driving Quick and Large Amplitude Contraction of Viologen-Incorporated Poly-l Lysine-Based Hydrogel by Reduction. AB - A glutaraldehyde-cross-linked poly-l-lysine-based hydrogel with pendant viologens was synthesized with various [viologen unit]/[Lys unit] ratios. The hydrogel with the ratio of 25% was extensively characterized. Characterization of the hydrogel revealed that (i) water content reaches 95.8%, (ii) unbound viologen unit is absent, and (iii) lyophilized gel, showing porous structure, is rewettable. The hydrogel in contact with a gold, glassy carbon, pyrolytic graphite, or ITO electrode was electroactive, showing voltammetric responses involving diffusion process. Occurrence of electron transfer between viologen sites was verified by ESR measurements. The electroreflectance spectrum demonstrated significant dimerization of one-electron-reduced forms, viologen radical cations. Most remarkably, reduction of the hydrogel by dithionite showed a 93% volume decrease, being near to the water content, at 100 s and finally 97% contraction at 380 s. The initial rate of contraction was 0.02 s-1, and the swelling weight ratio was over 17. The contraction rate was much faster than that observed when adding of redox-inactive salts in the outer medium. Recovery by reoxidation was relatively sluggish even when O2-saturated water was used. The quick and large-amplitude contraction with removal of water from the gel body should be the consequence of permeability of reductant, interchain pi-stacking of one-electron-reduced forms (viologen monoradical monocation), desolvation of viologen upon reduction, electron hopping between viologen units and its acceleration with contraction, and effective osmotic pressure difference. PMID- 30273493 TI - Coenzyme Q10 does not improve peripheral insulin sensitivity in statin-treated men and women; the LIFESTAT study. AB - Simvastatin is a cholesterol-lowering drug that is prescribed to lower the risk of cardiovascular disease following high levels of blood cholesterol. There is a possible risk of new onset diabetes mellitus with statin treatment but the mechanisms behind are unknown. Coenzyme Q10 (CoQ10) supplementation has been found to improve glucose homeostasis in various patient populations and may increase muscle GLUT4 content. Our aim was to investigate whether eight weeks of CoQ10 supplementation can improve glucose homeostasis in simvastatin treated subjects. Thirty-five men and women in treatment with minimum 40 mg of simvastatin daily were randomized to receive either 2 x 200 mg/d of CoQ10 supplementation or placebo for eight weeks. Glucose homeostasis was investigated with fasting blood samples, OGTT and IVGTT. Insulin sensitivity was assessed with the hyperinsulinemic, euglycemic clamp. Different indices were calculated from fasting samples and OGTT as secondary measures of insulin sensitivity. A muscle biopsy was obtained from the vastus lateralis muscle for muscle protein analyzes. There were no changes in body composition, fasting plasma insulin, fasting plasma glucose or 3hr-glucose with intervention, but HbA1c decreased with time. Glucose homeostasis measured as the AUC for glucose, insulin and C-peptide during OGTT was unchanged after intervention. Insulin secretory capacity was also unaltered after CoQ10 supplementation. Insulin sensitivity was unchanged but hepatic insulin sensitivity (HOMA2-%S) increased. No changes in muscle GLUT4 content was observed after intervention. CoQ10 supplementation does not change muscle GLUT4 content, insulin sensitivity or secretory capacity, but hepatic insulin sensitivity may improve. PMID- 30273494 TI - Genetic diversity and symbiotic efficiency difference of endophytic rhizobia of Medicago sativa. AB - Research on rhizobium diversity has paved the way for diversification of rhizobial germplasm resources. Seventy-three endophytic bacterial isolates were collected from seven tissues of five alfalfa cultivars in three geographic locations in Gansu, China. Restriction fragment length polymorphism (RFLP) fingerprinting of 16S rRNA and analysis of concatenated sequence of three housekeeping genes (atpD, glnII, and recA) and two symbiotic genes (nodC and nifH) were used for strain identification. Results showed that the endophytic strains were genetically diverse at different taxonomic levels, and Ensifer meliloti (31) and Agrobacterium radiobacter (12) are common Medicago sativa endophytic bacteria in Gansu, China. The nifH genes (97%-98% sequence identity) of E. meliloti strains were more diverse than the nodC genes (99%-100% sequence identity), even though the strains evolved from a common ancestor. The degree of dispersion of symbiotic phenotypes of E. meliloti strains on M. sativa 'Gannong No. 3', 'Gannong No. 9', and 'Qingshui' was much less than that on M. sativa 'Longzhong' and 'WL168HQ'. This suggested that the symbiotic efficiency of E. meliloti strains on the former three alfalfa cultivars was similar but on the latter two was discrepant. Their symbiotic efficiency differed primarily according to alfalfa cultivars and, to a lesser extent, to the tested strains, indicating the difference in the sensitivity of different alfalfa cultivars to rhizobial strains. PMID- 30273495 TI - Therapeutic potency of heat-shock protein-70 in the pathogenesis of colorectal cancer, current status and perspectives. AB - Heat-shock protein-70 (HSP70) is critical to the folding, stability and activity of several client proteins including many responsible for cancer cell proliferation, apoptosis, drug toxicity, and metastasis. Up-regulation of HSP70 is positively associated with increased tumorigenicity as well as poor survival in colon cancer patients, supporting the diagnostic, prognostic and therapeutic potencies of HSP70 in colorectal cancer. Administration of specific pharmacological inhibitors or gene knock-down for HSP70 suppresses tumor progression and enhances tumor cells chemosensitivity. This review summarizes different tumorigenic properties of HSP70 and potential therapeutic potency of HSP70 inhibitors as a novel strategy in colorectal cancer therapy for a better understanding and hence a better management of this disease. PMID- 30273496 TI - Altered driving performance of symptomatic Huntington's disease gene carriers in simulated road conditions. AB - OBJECTIVE: In clinical practice, patients with Huntington's disease (HD) often decide to solely drive in their own familiar neighborhoods and not on a motorway or in an unknown area. The aim of the study was to identify differences in driving performance between HD gene carriers and healthy individuals in simulated urban and motorway environments. METHODS: This cross-sectional study included 87 participants (28 premanifest HD, 30 manifest HD, 29 controls). All participants were active drivers and were assessed using a driving simulator, a driving history questionnaire, and the Unified Huntington's Disease Rating Scale. The driving simulator session included urban and motorway scenarios. Analysis of variance and Kruskal-Wallis tests were used to compare urban and motorway driving across all 3 groups. RESULTS: Manifest HD drove slower compared to controls and premanifest HD when speed limits increased (80 and 100 km/h) and they had a less steady speed compared to premanifest HD on the motorway and in a 30 km/h zone. Manifest HD also had a larger standard deviation of the lateral position (i.e., more weaving of the car/less vehicle control) compared to controls and premanifest HD on the motorway. CONCLUSIONS: Manifest HD drive more cautious in a driving simulator when speed limits increase compared to premanifest HD and controls and they have less vehicle control on the motorway. The driving simulator parameters are able to discriminate between manifest HD and healthy individuals, so a driving simulator seems a feasible tool to use when investigating changes in driving in manifest HD.

PMID- 30273497 TI - Sustained Quality Improvement in Outcomes of Preterm Neonates of <29 Weeks' Gestational Age: Results from the Evidence-based Practice for Improving Quality Phase 3 (EPIQ-3). AB - Quality improvement initiatives in neonatology have yielded positive results; however, few programs have demonstrated sustainability. We evaluated an ongoing, national quality improvement initiative (Evidence-based Practice for Improving Quality [EPIQ-3]) on outcomes of preterm neonates 220-286 weeks' gestational age (GA). Data from 7459 neonates admitted to 25 Canadian centers between 2013 and 2017 were studied. Trends in mortality and major morbidities were evaluated. The neonates of 220-236 weeks' GA increased from 90 in 2013 to 139 in 2017 without a significant change in any other GA categories. In the entire cohort, the odds of composite outcome of mortality or any major morbidity (adjusted odds ratio [AOR] 0.72, 95% confidence interval [CI] 0.61-0.84) and of necrotizing enterocolitis (AOR 0.66, 95%CI 0.49-0.89) were lower in 2017 compared to 2013. When calculated per year, the odds of composite outcome (AOR 0.93, 95%CI 0.89-0.97) and odds of necrotizing enterocolitis (AOR 0.89, 95%CI 0.82-0.96) decreased significantly. Among the subgroup of 260-286 weeks' GA, the odds of composite outcome (AOR 0.63, 95%CI 0.51-0.79), necrotizing enterocolitis (AOR 0.44, 95%CI 0.26-0.73) and nosocomial infection (AOR 0.64, 95%CI 0.49-0.84) were reduced. The collaborative, multidisciplinary, nationwide EPIQ-3 program improved outcomes of preterm neonates, and the improvement was sustainable over 5 years. PMID- 30273499 TI - The effectiveness of voluntary policies and commitments in restricting unhealthy food marketing to Canadian children on food company websites. AB - Marketing unhealthy foods and beverages to children (M2K) fosters poor dietary patterns, increasing obesity and noncommunicable disease risk. Federal restrictions on M2K have been under development in Canada since 2016; however, at present, M2K is mostly self-regulated by food companies. This study aimed to compare M2K on Canadian websites of food companies with and without voluntary policies or commitments in this area. A systematic content analysis of company websites was conducted in spring/summer 2017 for major packaged food (n = 16), beverage (n = 12), and restaurant chain (n = 13) companies in Canada. M2K policies were sourced from company websites and published corporate documents. Sixteen companies (43%) reported national and/or global M2K policies, while 21 companies (57%) had no published policies. The websites of Canadian companies (n = 154) were scanned for child-directed products and marketing; type and frequency of marketing techniques were recorded. Child-directed marketing appeared on 19 websites of 12 companies (32%), including 9 companies with M2K policies. Websites featured products with unconventional flavours, colours, shapes, or child oriented packaging, and used promotional characters, contests, games, activities, or lettering and graphics appealing to children. The nutritional quality of products marketed to children was evaluated using a nutrient profile model developed by Health Canada for proposed M2K regulations. Of the 217 products marketed to children, 97% exceeded Health Canada's proposed ~5% Daily Value threshold for saturated fat, sodium, and/or sugars, 73% of which were products from 9 companies with policies. These findings highlight the limitations of self regulation in restricting M2K on food company websites, reinforcing the need for government regulations. PMID- 30273500 TI - Concurrent exercise circuit protocol performed in public fitness facilities meets the ACSM guidelines for energy cost and metabolic intensity among older adults in Rio de Janeiro City. AB - The present study investigated whether a single bout of concurrent exercise (Ex Rx) at Third Age Academies (TAAs) of Rio de Janeiro City meets the American College of Sports Medicine (ACSM) guidelines for energy cost and metabolic intensity in older adults. Nine subjects (5 males and 4 females, aged 63-80 years) visited the laboratory for clinical screening, anthropometrical, resting and maximal VO2 assessments. Thereafter, subjects performed an Ex Rx circuit, consisting of a single circuit alternating aerobic and resistance exercises at outdoor exercise equipment using body mass as the load (total of 9 exercises, 1-2 sets of 15 repetition). Expired gases were collected during exercise bouts via a metabolic cart. The mean observed energy cost value of 169.1 kcal was slightly greater than the minimum value of 150 kcal reported in the ACSM's guidelines (p = 0.018). Like energy cost, all the intensity markers adopted to analyze the physiological strain induced by the Ex Rx circuit significantly exceeded their reference values for moderate-intensity [reference values: 3.2 METs (mean observed value = 4.6 METs, p = 0.002); 40% of oxygen uptake reserve (mean observed value = 51.5%, p = 0.040); 40% of heart rate reserve (mean observed value = 64.1%, p < 0.001), according to the ACSM's guidelines. In conclusion, a single bout of Ex Rx circuit performed in TAAs at Rio de Janeiro City was able to induce a physiological strain (i.e. energy cost and intensity) compatible with the ACSM recommendations for eliciting health benefits among older adults. PMID- 30273501 TI - Evaluation of MOS social support in low-income caregivers of African American children with poorly controlled asthma. AB - OBJECTIVE: The purpose of this study was to examine the factor structure of the Medical Outcomes Study Social Support Survey (MOS-SSS) in a sample of low-income, urban caregivers of African American children with poorly controlled asthma. Although the MOS-SSS is a commonly used measure of social support, its psychometric properties have not been studied in this population. METHODS: Confirmatory factor analysis was conducted to determine the most appropriate factor structure for the MOS-SSS in caregivers of African American children with frequent Emergency Department visits for uncontrolled asthma. The following models were tested and compared using established fit statistics: an 18-item second-order four factor model, an 18-item four factor model, a bifactor model and an 18-item one factor model with nested models. RESULTS: Participating caregivers were single (75.6%) and female (97%). An 18-item one factor version of the scale had the best fit statistics compared to the other models tested: [Formula: see text](142) = 308.319, p > 0.001; Root mean square error of approximation (RMSEA) = 0.077; CFI (Comparative Fit Index) = 0.990; and Tucker Lewis Index (TLI) = 0.988. Construct validity was supported by a statistically significant negative relationship between our final MOS-SSS model and caregiver depressive symptoms ([Formula: see text]= -0.374, p < 0.001). CONCLUSIONS: The 18 item one factor MOS-SSS may be appropriate for use in research and clinical practice with caregivers of African American children with poorly controlled asthma. It appears promising as a mechanism to advance understanding of relationships between social support and asthma outcomes in this vulnerable population. PMID- 30273502 TI - The association of prenatal risk factors with childhood asthma. AB - OBJECTIVE: The purpose of the study was to examine the relationship of maternal complications during pregnancy and prenatal exposures with childhood asthma among low-income families in Karachi, Pakistan. METHODS: Parents/guardians of children with and without asthma visiting a charity hospital were enrolled. Information about prenatal and perinatal exposures was collected. Univariable and multiple stepwise logistic regression analysis were conducted to explore the relationship of socio-demographic, maternal complications during pregnancy, access to prenatal care, and exposure to animals and pests while pregnant with childhood asthma. RESULTS: Maternal symptoms of nocturnal cough (adjusted OR [aOR = 2.87, 95% CI = 1.60-5.14) and wheezing (aOR = 5.57, 95% CI = 2.32-13.37) during pregnancy significantly increased the odds of childhood asthma. The family history of asthma or hay fever, also elevated the odds of childhood asthma (adjusted OR [aOR] = 5.86 (3.03-11.34). The odds of asthma among children whose mothers received prenatal care by Dai, an unskilled health worker, were significantly elevated. Lastly, prenatal exposure to rats/mice and contact with goats while pregnant was significantly associated with childhood asthma. Whereas, prenatal exposure to cows/cattle reduces the odds of childhood asthma. CONCLUSIONS: This study identified important maternal and prenatal risk factors for childhood asthma, the majority of which are avoidable. Appropriate steps are needed to create awareness about the prenatal risk factors in this population. PMID- 30273503 TI - Osmolytes in vaccine production, flocculation and storage: a critical review. AB - Small molecule osmolytes, responsible for protecting stresses have long been known to rescue proteins and enzymes from loss of function. In addition to protecting macromolecules integrity, many osmolytes also act as potential antioxidant and also help to prevent protein aggregation, amyloid formation or misfolding, and therefore are considered promising molecules for neurodegenerative and many other genetic diseases. Osmolytes are also known to be involved in the regulation of several key immunological processes. In the present review we discuss in detail the effect of these compounds on important aspects of vaccines i.e., increasing the efficiency, production and purification steps. The present review therefore will help researchers to make a better strategy in vaccine production to formulation by incorporating specific and appropriate osmolytes in the processes. PMID- 30273504 TI - Patients' Needs of Religion/Spirituality Integration in Two Mental Health Clinics in the Netherlands. AB - INTRODUCTION: In the last decades, the attention for religion/spirituality (R/S) in mental health care (MHC) has considerably increased. However, patients' preferences concerning R/S in treatment have not often been investigated. The aim of this study was to find out how patients in clinical multidisciplinary MHC want R/S to be addressed in their care. METHODS: Thirty-five semi-structured interviews were carried out between September 2015 and July 2016 among patients in a secular and a Christian MHC in the Netherlands. Qualitative inductive content analysis was performed, using Atlas Ti. RESULTS: Patients appreciated (1) individual R/S conversations between patients and care team members (mainly nurses), (2) a familiar R/S environment, (3) a special R/S program and (4) contact with their R/S network. Patients varied in their presentation of R/S care needs from (a) explicit, mostly in the Christian MHC, to (b) implicit, predominantly in the secular MHC, or showed (c) hidden R/S care needs. A non acute stage of the illness and R/S affinity of the mental health professionals, were classified as possible conditions for addressing R/S. Discussion and implications for practice: Nurses are recommended to be aware of the diversity of patients' R/S care needs. Actively addressing R/S may help in recognizing implicit or even hidden R/S care needs. Further considerations on whether and how to respond to patients' R/S care needs would be justified. PMID- 30273505 TI - CMTR1-ALK: an ALK fusion in a patient with no response to ALK inhibitor crizotinib. AB - The targeted treatment of advanced non-small cell lung cancer (NSCLC) harboring genomic rearrangement of ALK is a paradigm for personalized oncology. More than 15 different ALK fusion partners have been discovered in NSCLC patients. Most of these ALK fusions responded well to the ALK inhibitor crizotinib. Crizotinib is an oral MET/ALK inhibitor used as first-line therapy in the treatment of advanced NSCLC harboring ALK rearrangement. An understanding of the mechanisms by which tumors harbor primary drug resistance or acquired resistance to targeted therapies is critical for predicting which patients will respond to a specific therapy and for the identification of additional targetable pathways to maximize clinical benefits. Cap methyltransferase 1(CMTR1) also known as hMTr1, which is translate a human cap1 2'-o-ribose methyltransferase. Here, we report the newly found ALK fusion, CMTR1-ALK, in a patient who has no response to the ALK inhibitor crizotinib. The results remind us that detecting ALK status is important, but that determining the ALK fusion type and function may be more important for patient. PMID- 30273506 TI - Meningococcal disease in adolescents and young adults: a review of the rationale for prevention through vaccination. AB - Invasive meningococcal disease (IMD) caused by Neisseria meningitidis is characterized by high mortality and morbidity. While IMD incidence peaks in both infants and adolescents/young adults, carriage rates are often highest in the latter age groups, increasing IMD risk and the likelihood of transmission. Effective vaccines are available for 5 of 6 disease-causing serogroups. Because adolescents/young adults represent a significant proportion of cases, often have the highest carriage rate, and have characteristically low vaccination adherence, efforts should be focused on educating this population regarding long-term consequences of infection and the importance of meningococcal vaccination in prevention. This review describes the role of adolescents/young adults in meningococcal transmission and the clinical consequences and characteristics of IMD in this population. With a focus on countries with advanced economies that have specific meningococcal vaccination recommendations, the epidemiology of meningococcal disease and vaccination recommendations in adolescents/young adults will also be discussed. PMID- 30273507 TI - Comparison of three sample size calculation methods for non-inferiority vaccine trials with multiple continuous co-primary endpoints. AB - Clinical trials that study immunogenicity of combination vaccines often have less power than desirable. To make up for the reduction in statistical power at the study level, researchers have to increase the study sample size. To study immunogenicity variables, we used the geometric mean concentration of immune response after vaccination as immunologic endpoint and compared 3 sample size calculation methods: the "Inflation factors" method, the "Incrementing" method, and the "Bonferroni correction" method when there are multiple continuous co primary endpoints. The parameters were set according to the actual situation of the use of combination vaccines and the simulation results were used as reference. The present study demonstrates that all 3 methods are applicable when the effect size of each endpoint is similar and the endpoints are at most weakly correlated, but when there is a true difference in effect sizes among endpoints, the "Incrementing" method has the best performance. PMID- 30273508 TI - Recruitment, use, and satisfaction with a web platform supporting families of children with suspected or diagnosed developmental coordination disorder: a randomized feasibility trial. AB - OBJECTIVES: To determine the feasibility of recruiting families of children with suspected or diagnosed developmental coordination disorder (sdDCD) and explore their satisfaction with a web-based intervention Design. A feasibility randomized trial was conducted. Participants were the parents of 5-12-year-old children with sdDCD. The intervention group had access to online resources, group and private forums, and videoconferencing with a therapist. Main outcomes were recruitement and retention rates. Satisfaction was documented through a post-intervention survey and interview. RESULTS: The recruitment rate was seven participants per month (n = 28 participants) and retention rate was 68%. Satisfaction was moderate. No differences in use and satisfaction were observed between groups. Participants formulated recommendations for improving the intervention, including targeting families earlier in the diagnosis process, and pre-scheduling meetings with therapists. CONCLUSIONS: This study demonstrated the feasibility of future trials, and highlighted avenues for improvement. Parent involvement during the development of the intervention is discussed at length. ABBREVIATIONS: DCD: Developmental Coordination Disorder; sdDCD: suspected or diagnosed Developmental Coordination Disorder; RCT: randomized-controled trial. PMID- 30273509 TI - Variation factors of stereotypical hand movements in subjects with Rett syndrome. AB - BACKGROUND: Stereotypical hand movements have been observed in most individuals diagnosed with Rett syndrome. OBJECTIVES: To investigate factors that increase or decrease hand stereotypies in individuals with Rett syndrome. METHODS: A questionnaire regarding hand stereotypies or purposeful hand behaviours was sent to 1016 schools for special needs education and 204 facilities in Japan. RESULTS: Information was acquired from 216 cases (3-53 years old) with Rett syndrome; 81.9% and 87.6% of individuals had factors that increased and decreased stereotypical hand movements, respectively. Stereotypies were mainly increased by displeasure (63.8%) or pleasure (48.5%), and decreased by somnolence (43.5%), pleasure (30.0%), or food (24.1%). CONCLUSION: Emotion was the main factor increasing stereotypical hand movements, whereas there were a large number of factors that decreased these movements. The factors that decrease stereotypies could be useful to prevent the skin problems or joint contracture observed in patients with Rett syndrome. PMID- 30273510 TI - Dupilumab safety and efficacy in uncontrolled asthma: a systematic review and meta-analysis of randomized clinical trials. AB - OBJECTIVE: We aimed to perform a meta-analysis evaluating the efficacy and safety of dupilumab in patients with uncontrolled asthma. DATA SOURCE: A search of electronic databases was performed using PubMed, Cochrane library and Embase. STUDY SELECTION: The literature search was conducted independently by two reviewers. Only randomized controlled trials (RCTs) that compared between placebo and dupilumab in patients with uncontrolled asthma were included in this analysis. Pooled risk ratios (RRs) and mean differences (MDs) with their corresponding 95% confidence intervals (CIs) were calculated for dichotomous and continuous data, respectively. RESULTS: A total of four RCTs representing 2,992 patients were included. Pooled analysis showed significant reductions of the annualized rate of severe asthma exacerbation in the dupilumab group compared with placebo (RR 0.44; 95% CI 0.35-0.055; P < 0.01; I2 = 42%). In addition, the absolute forced expiratory volume at 1 s (FEV1) changes were significantly increased for the dupilumab group (MD 0.14; 95% CI: 0.12-0.17; P < 0.01; I2 = 0%). Finally, there were no significant differences between both groups in the development of any adverse event, serious adverse events, adverse events leading to death, discontinuation of medication due to adverse event or the occurrence of upper respiratory tract, influenza or bronchitis infections. However, dupilumab was associated with an increased risk of injection site reactions compared with placebo (RR 1.91; 95% CI 1.41, 2.59; P < 0.01; I2 = 24%). CONCLUSION: Among patients with uncontrolled asthma, the addition of dupilumab was associated with a reduced risk of severe asthma exacerbations and improvement in FEV1 without an increased risk of adverse events apart from injection site reactions with dupilumab. PMID- 30273511 TI - On the lighter side: Medicine or etiquette? Rethinking a lecturer's teaching assignment. AB - PURPOSE: To investigate the extent to which medical students demonstrate politeness. With respect to patient-physician interactions, politeness appears to be a factor in therapeutic success, perhaps because it might induce greater patient compliance. METHOD: We assessed 354 third-semester medical students on one type of politeness, that is the percentage of students who greeted the teacher upon entering the lecture room. RESULTS: Overall, 47% of the students initiated a greeting and this percentage did not change when the lecturers wore white coats. Females were less likely to initiate a greeting (35%) than males (55%). CONCLUSION: The results lead us to question whether university lecturers should strictly stick to their content of the curriculum or should they also teach their students about etiquette related to good clinician-patient relationships? PMID- 30273513 TI - Disease of the Year: Differential Diagnosis of Uveitic Macular Edema. AB - Uveitic cystoid macular edema (UME) is an important cause of visual morbidity among patients with both infectious and non-infectious uveitis. UME may be associated in more than 30% cases of active uveitis. However, even patients with minimal features of intraocular inflammation may develop recurrent or chronic UME. Therefore, the evaluation and management of UME in patients with uveitis may be challenging. A number of vitreoretinal pathologies may result in UME and accumulation of fluid in the intra- or subretinal space. These need to be carefully distinguished from each other so that appropriate management can be initiated. All types of uveitis, including anterior uveitis (where the primary site of inflammation is not in the posterior segment) can present with UME. Other conditions such as diabetes, and surgery, can present with macular edema. This index review highlights various differential diagnoses of UME and provides illustrative case examples with multimodal imaging evaluation. PMID- 30273512 TI - A simple and safe antibody neutralization assay based on polio pseudoviruses. AB - The evaluation of the immunogenicity of Sabin strain based Inactivated Poliovirus Vaccines (sIPV) necessitates the use of wild strains in neutralization assays to assess the potential cross-reactivity of antibodies. The live virus strains including wild and Sabin strains must be handled in level 3 biocontainment laboratories. To develop an alternative assay without the use of a live virus, we constructed Mahoney, MEF-1, and Saukett pseudovirions by inserting luciferase reporter genes into intact capsid proteins. Afterward, we developed a pseudovirus based neutralization test (pNT) and evaluated for the specificity and reproducibility. We tested serum samples from a clinical trial on sIPV vaccines by pNT and compared the results with those obtained from conventional neutralization tests (cNT). A strong correlation was observed between two methods, with the correlation coefficients of all three types of IPV vaccines being greater than 0.82 (p < 0.0001). The Geometric Mean Titer (GMT) values obtained by pNT were approximately four times higher than that by cNT, revealing the better sensitivity of pNT. In conclusion, pNT is a safe, rapid and sensitive quantitative assay with the potential of being an alternative for the evaluation of the potency of polio vaccines. PMID- 30273514 TI - Effect of Rapamycin Microspheres in Sjogren Syndrome Dry Eye: Preparation and Outcomes. AB - PURPOSE: To prepare a drug delivery system of rapamycin poly-3-hydroxybutyrate-co 3-hydroxyvalerate microspheres (RPM) and analyze its effect on the eyes of a Sjogren's syndrome mouse model. METHODS: RPM was generated using a solvent evaporation method, and observed under light and electron microscopy. No obesity diabetes (NOD) mice with Sjogren's syndrome were randomized into normal saline, empty microspheres, and RPM groups, with healthy Kunming mice as the controls. Dry eye signs were assessed using a slit lamp. Tear secretion, corneal fluorescein, keratoconjunctival rose bengal, and conjunctival impression cytology were recorded. RESULTS: RPM was smooth and spherical, about 20-50 MUm in diameter, without agglomeration or adhesion. Mice receiving RPM secreted more tears. And they had a normal corneal histology, exhibiting reduced corneal fluorescein, rose bengal staining, and conjunctival impression cytology. CONCLUSION: RPM improved the signs of dry eyes, improved tear secretion, decreased corneal endothelial cell injury, and improved histological damage of the cornea in NOD mice. PMID- 30273515 TI - The Use of Differential Reinforcement of Other Behaviours to Establish Inhibitory Stimulus Control for the Management of Vocal Stereotypy in Children with Autism. AB - OBJECTIVE: This study examined the efficacy of an inhibitory stimulus control procedure (ISCP) for the management of vocal stereotypy in three children with autism. METHOD: During discrimination training, implemented within a changing criterion design, participants were taught that there were no consequences for vocal stereotypy in the absence of an inhibitory stimulus but that differential reinforcement procedures were in effect in the presence of the stimulus. Functional control of the inhibitory stimulus was subsequently assessed within a reversal design. RESULTS: Inhibitory stimulus control was established during discrimination training, with participants inhibiting vocal stereotypy for 30 min periods in the presence of the inhibitory stimulus. Reductions in vocal stereotypy were maintained in the presence of the inhibitory stimulus and in the absence of further programmed consequences. DISCUSSION: This study extends current knowledge by demonstrating the efficacy of ISCPs paired with reinforcement only, and illustrating the functional control of the inhibitory stimulus. PMID- 30273516 TI - Glutaminase inhibitors: a patent review. AB - INTRODUCTION: The kidney-type glutaminase (GLS) controlling the first step of glutamine metabolism is overexpressed in many cancer cells. Targeting inhibition of GLS shows obvious inhibitory effects on cancer cell proliferation. Therefore, extensive research and development of GLS inhibitors have been carried out in industrial and academic institutions over the past decade to address this unmet medical need. Areas covered: This review covers researches and patent literatures in the field of discovery and development of small molecule inhibitors of GLS for cancer therapy over the past 16 years. Expert opinion: The detailed ligand receptor interaction information from their complex structure not only guides the rational drug design, but also facilitates in silico structure-based virtual ligand screening of novel GLS inhibitors. Multi-drug combination administration is of great significance both in terms of safety and efficacy. PMID- 30273517 TI - Long-term physical and mental health outcomes associated with traumatic brain injury severity in post-9/11 veterans: A retrospective cohort study. AB - OBJECTIVES: To examine long-term outcomes of self-reported physical and mental health among Post-9/11 Veterans stratified by traumatic brain injury (TBI) severity, we hypothesized that more severe TBI would be associated with significantly poorer outcomes. METHODS: A prospective longitudinal survey of physical and mental health status was conducted with a national cohort of Post 9/11 Veterans. We then used generalized linear models (GLM) to assess the unique contribution of TBI severity on long-term outcomes after controlling for socio demographic characteristics, comorbidity phenotypes, and deployment experiences. RESULTS: TBI of any severity was associated with significantly poorer outcomes relative to the No TBI group. However, the manifestation of these outcomes identified in our study differed meaningfully by TBI severity level. CONCLUSIONS: Veterans with any TBI exposure experience poorer long-term outcomes than those with no TBI even when covariates are considered. In particular, measures of somatization, PTSD symptom distress, and depression indicate pervasive and long term health concerns among individuals with TBI. Additional research is required to fully explicate what appear to be complex relationships among TBI severity, physical and mental well-being, combat exposures, and socioeconomic resources in this population. PMID- 30273518 TI - Mitogen-activated protein kinase kinase 6 negatively regulates anthocyanin induction in Arabidopsis. AB - Arabidopsis mitogen-activated protein (MAP) kinase kinase 6 (MKK6) has previously been shown to play important roles in plant immunity and cytokinesis. Here we report that it is also involved in the negative regulation of anthocyanin biosynthesis in Arabidopsis. Elevated anthocyanin levels are observed in mkk6 knock out mutant plants. RNA-sequencing analysis revealed that the expression level of MYB75 (Myb transcription factor 75), which encodes a key positive regulator of anthocyanin biosynthesis, is up-regulated in mkk6 mutant plants, suggesting that increased MYB75 expression contributes to the elevated anthocyanin levels. In addition, suppression of high sucrose-induced anthocyanin production by pathogen associated molecular pattern-triggered immunity is also dependent on MKK6, further supporting that MKK6 is a key negative regulator of anthocyanin biosynthesis in Arabidopsis. PMID- 30273519 TI - Quality of dying and quality of end-of-life care of nursing home residents in six countries: An epidemiological study. AB - BACKGROUND:: Nursing homes are among the most common places of death in many countries. AIM:: To determine the quality of dying and end-of-life care of nursing home residents in six European countries. DESIGN:: Epidemiological survey in a proportionally stratified random sample of nursing homes. We identified all deaths of residents of the preceding 3-month period. Main outcomes: quality of dying in the last week of life (measured using End-of-Life in Dementia Scales - Comfort Assessment while Dying (EOLD-CAD)); quality of end-of-life care in the last month of life (measured using Quality of Dying in Long-Term Care (QoD-LTC) scale). Higher scores indicate better quality. SETTING/PARTICIPANTS:: Three hundred and twenty-two nursing homes in Belgium, Finland, Italy, the Netherlands, Poland and England. Participants were staff (nurses or care assistants) most involved in each resident's care. RESULTS:: Staff returned questionnaires regarding 1384 (81.6%) of 1696 deceased residents. The End-of-Life in Dementia Scales - Comfort Assessment while Dying mean score (95% confidence interval) (theoretical 14-42) ranged from 29.9 (27.6; 32.2) in Italy to 33.9 (31.5; 36.3) in England. The Quality of Dying in Long-Term Care mean score (95% confidence interval) (theoretical 11-55) ranged from 35.0 (31.8; 38.3) in Italy to 44.1 (40.7; 47.4) in England. A higher End-of-Life in Dementia Scales - Comfort Assessment while Dying score was associated with country ( p = 0.027), older age ( p = 0.012), length of stay ?1 year ( p = 0.034), higher functional status ( p < 0.001). A higher Quality of Dying in Long-Term Care score was associated with country ( p < 0.001), older age ( p < 0.001), length of stay ?1 year ( p < 0.001), higher functional status ( p = 0.002), absence of dementia ( p = 0.001), death in nursing home ( p = 0.033). CONCLUSION:: The quality of dying and quality of end-of-life care in nursing homes in the countries studied are not optimal. This includes countries with high levels of palliative care development in nursing homes such as Belgium, the Netherlands and England. PMID- 30273520 TI - Hispanic Caregiver Experiences Supporting Positive Postschool Outcomes for Young Adults With Disabilities. AB - The rate of competitive employment, or employment in community settings for minimum wage or higher, of working-age individuals with disabilities trails behind individuals without disabilities in the United States. These statistics are even more alarming among Hispanic individuals who have disabilities. The purpose of this study was to explore the negative and positive experiences of Hispanic caregivers from a Midwestern state as they support their family members with disabilities to achieve positive postschool outcomes, including competitive employment. We conducted semistructured interviews with 13 caregivers of family members with disabilities aged 14-25 years. Three key themes emerged from our analysis: (a) negative experiences with school educators, (b) negative experiences with community-based service providers, and (c) positive experiences and strategies for overcoming barriers. Implications for practice and future research are discussed.

PMID- 30273522 TI - "We Had to Keep Pushing": Caregivers' Perspectives on Autism Screening and Referral Practices of Black Children in Primary Care. AB - Black children with autism spectrum disorder (ASD) are diagnosed later than their White peers, are more likely to be misdiagnosed, and are less likely to receive early intervention services or a developmental evaluation by three years old. Using a grounded theory approach, we solicited the perspectives of parents and other primary caregivers of Black children with ASD on barriers and facilitators to ASD screening and referrals in primary care. A socioeconomically diverse sample of 22 female caregivers participated. Four themes emerged. First, while some caregivers noted their child's primary healthcare providers facilitated a timely ASD diagnosis, other participants reported these providers ignored early concerns about child developmental delays. Second, many participants felt racial bias negatively impacted caregiver-primary healthcare provider interactions. Third, legal/custodial issues slowed caregivers' abilities to follow up on referrals from their primary healthcare providers. Finally, caregivers described denial, shame, and stigma relating to ASD in the Black community as possible factors for delayed follow up to referrals. Differences based on socioeconomic status are discussed. Efforts to improve family-centered, culturally relevant care for all Black caregivers raising children with or at-risk for ASD are needed, particularly for those families experiencing the multiple effects of poverty.

AB - Grandparents can play critical roles in the lives of children with intellectual and developmental disabilities and their families. However, current research and understanding around grandparent roles and experiences is limited. The purpose of this qualitative study was to examine the roles and experiences of grandparents supporting children with disabilities. In this article, the voices of grandparents with diverse experiences are presented. Key themes that emerged were the role of the grandparent, boundaries in roles and space, navigating family dynamics, and the general experiences of grandparenting. These findings have implications for the types of supports provided to grandparents and for practitioners working with families who have actively involved grandparents. PMID- 30273525 TI - Empowerment and Resilience in Families of Adults With Intellectual and Developmental Disabilities. AB - Using the family resilience model, we examined the association between empowerment, family member age, length of institutionalization, and resilience among family members of relatives with intellectual and developmental disabilities (IDD) following deinstitutionalization. Participants included 56 family members whose relatives with IDD recently transitioned to community living. Results strongly indicate empowerment plays a key role in positive family adaptation. Thus, following a relative's move from an institution to the community, empowerment is a promising form of protection that holds potential to increase family resilience. The results of the current study support the family resilience model as a foundation for future research regarding how families navigate significant transitions throughout the lifespan. Implications for practice and policy are provided. PMID- 30273527 TI - Resumenes al Espanol. PMID- 30273526 TI - Parent Engagement in the Transition From School to Adult Life Through Culturally Sustaining Practices: A Scoping Review. AB - The increasingly diverse population in the United States calls for schools to address the breadth of cultural histories students bring with them to the classroom. High school students with disabilities are also diverse in terms of cultural histories, race, ethnicities, religions, and citizenship. These factors intersect as families engage in planning for the transition to adulthood. A requisite for culturally diverse families with young adults who receive services under the educational category of intellectual disability (ID) are school professionals who can meaningfully collaborate. This review of literature from peer-reviewed journals seeks to understand if culturally responsive practices are utilized with culturally and linguistically diverse (CLD) families during transition planning. This review also explored whether culturally sustaining practices strengthen partnerships between teachers and CLD families and adolescents with disabilities, including those with ID. Implications are associated with how teachers can perceive diversity from a strengths perspective as a vital component of transition planning.

This has led to propose that CNS infiltration is an early event in the evolution of the disease. We intend to evaluate the role of magnetic resonance imaging (MR) at diagnosis to detect early SNC compromise. Methods: Prospective longitudinal cohort's study in DGCB patients treated at Hospital de Clinicas between 2013 and 2015. Skull MRI was performed in all patients at diagnosis and lumbar puncture was done according to predefined risk factors. Results: 35 patients were analyzed. Median age: 68 years (24-85 years). Stage III-IV: 62%, 57% good prognosis according to RIPI score and 43% poor prognosis. MRI was performed in all patients, with no pathological findings in any of them. Twenty-one patients fullfilled criteria for cerebrospinal fluid study. Twenty-two patients were studied and received intrathecal methotrexate prophylaxis. Meningeal relapse was observed in a single patient who had negative studies at diagnosis and had received complete prophylaxis at the end of the 6 R-CHOP series. Conclusions: Only one of the 35 patients relapsed in the CNS. This patient had a noral MRI and CSF study at diagnosis and had received prophylaxis with intrathecal chemotherapy. This results lead us to believe that the value of MRI to detect early infiltration in asymptomatic patients at diagnosis is low. PMID- 30273530 TI - [Laparoscopic Surgery for isolated lymph nodes recurrence in gynecology. Experience in Argentina.] AB - Objectives: to describe the perioperative and oncological outcomes of a serie of cases treated with laparoscopic surgery for isolated nodal metastasis of gynecologic malignancies at the Gynecology Service of Hospital Italiano de Buenos Aires and conduct a literature review on the surgical treatment provided to patients with this condition. Methods: A search was conducted in the surgery records of the Gynecology Service of Hospital Italiano of patients who underwent laparoscopic cytoreductive surgery for isolated nodal recurrence of a gynecologic primary tumor in the period 2009-2015. The medical records were reviewed and data on the patients' characteristics, the tumor, the surgery and its complications were collected and analyzed. A literature search was conducted in Pubmed by the term "isolated nodal recurrence in gynecology" and a subsequent snowball search was performed. Results: As results, nine patients are presented. The median age was 66 years old (RI 7). The initial cancer location was: ovary (n=3), endometrium (n=3), cervix (n=2) and breast (n=1). The location site of the single nodal recurrence was the para-aortic area (n=8) and the pelvic area (n=1). The median of the disease-free interval to recurrence was 42.8 months (RI 40.2). Either the retroperitoneal or the transperitoneal approach was used based on the location of the recurrence. The median surgery time was 120 minutes (RI 36). No conversion to laparotomy was performed in any patient. No intraoperative or postoperative complications were reported, nor any requirement for blood transfusion. The median hospital stay was 36 hours. Adjuvant treatment with chemotherapy was applied to 8/9 patients. Only one patient recurred in para aortic lymph nodes and peritoneal carcinomatosis after eight months and died of her disease. The literature review confirms the possibility of laparoscopic resection of the single nodal recurrence with low complication rate. Conclusion: The laparoscopic lymph node cytoreductive surgery is a valid and safe treatment option considering the perioperative and oncological outcomes in our hospital. PMID- 30273531 TI - Incidence of hospital-acquired venous thromboembolic disease. AB - BACKGROUND: There is limited knowledge of the incidence of venous thromboembolic disease (VTE) during hospitalization, since most of these are community-based data. PURPOSE: To estimate the incidence rate (IR) of VTE developed during hospitalization. METHODS: Prospective cohort of all inpatients admitted in a university tertiary hospital, in Argentina. The inclusion criteria were defined as: adult patients consecutively admitted from July/2006 to August/2013, for any cause. Patients admitted for VTE were excluded; all patients at the time of admission were free of event. Each person was followed contributing time at risk, from admission to event, discharge or death. VTE incident cases were captured from the Institutional Registry of Thromboembolic Disease (ClinicalTrials.gov Identifier NCT01372514). Incidence rate was calculated with 95% confidence intervals. RESULTS: The crude incidence rate of VTE for clinical patients was 0.49 (95%CI 0.45-0.55) per 1,000 cases person-days, and IR adjusted for WHO was 0.23 (95%CI 0.19-0.26). The crude IR of VTE for surgical patients was 0.25 (95%CI 0.23-0.27), and IR adjusted for WHO was 0.13 (95%CI 0.10-0.17). The incidence rate ratio (IRR) for VTE shows that surgical admission reduces the IRR and age categories increases the thrombosis rate risk, after adjustment for age category, sex and surgical admission. CONCLUSIONS: This study suggests that there is a high risk of VTE in hospitalized patients and is still a frequent problem.

Feasibility study. It was a study quasi- experimental whit control group carried out in a middle-level public school. The sample consisted of 58 adolescents in the intervention group and 77 in the control group. After the intervention increased consumption of agro-ecological food (from 26% to 74% p<0,05). Changes were detected in acquired knowledge about agroecology in the classroom level going from 37% to 63% (p< 0,05). Positive changes detected in awareness with the environment and relationship (p<0,05). It was evidenced that the implementation of school agroecology can provide resolutive contributions to some of the problems the health related quality of life of adolescents. PMID- 30273533 TI - [The nutritional status analysis in physical education students, associated with eating habits and level of physical activity] AB - INTRODUCTION: numerous studies show that the college-aged student modifies their eating habits and levels of physical activity and, consequently, their Body Mass Index (BMI) exceeds healthy values (?25). General objective: to analyze the nutritional status in students of two Physical Education Teaching training Institutes, located in Cordoba, Argentina, and their possible association with eating behaviours and level of physical activity. Method: observational, cross sectional and descriptive study. 134 students were studied.To assess nutritional status, the MBI was measured. To investigate about food selection and habits which accompanied the ingestion, a survey was used based on the recommendations from the Food Guidelines for the Argentine Population. To estimate energy expenditure by physical activity, the International Physical Activity Questionnaire (IPAQ) was used, in short format, in the Spanish version. Results: Se podria presumir que el saludable estado nutricional de la poblacion estudiada se debe a sus habitos alimentarios mayormente saludables y, principalmente, a su alto nivel de actividad fisica. No obstante, el seguimiento de esta poblacion, en un estudio longitudinal, podria ratificar o rectificar estas primeras presunciones. Conclusion: it can be assumed that the healthy nutritional status of the study population is due to their mostly healthy eating habits, and mainly to their high level of physical activity. PMID- 30273535 TI - Are there any risk factors for developing complications with the use of retrievable vena cava filters in orthopaedic surgery? AB - BACKGROUND: In high-risk patients, common prophylaxis may be insufficient to prevent thromboembolic events after orthopaedic procedures. In this scenario, a retrievable vena cava filter (VCF) could be considered as an alternative, although it's use remains controversial. Therefore, we asked: (1) what is the overall mechanical complication rate associated with the use of retrievable VCFs in orthopaedic surgery?, (2) what is the association with thromboembolic disease (TED) recurrence, post-thrombotic syndrome and/or major bleeding according to different surgical characteristics?, (3) What is the overall mortality rate attributed to VCF use? METHODS: We retrospectively analyzed a cohort of 68 patients who underwent orthopaedic surgery with a previous diagnosis of TED, in whom a retrievable VCF was placed. Permanent filters were excluded. We studied the filter's mechanical complications and considered as possible outcomes death and 3 hematologic complications: TED recurrence, post-thrombotic syndrome and major bleeding. To estimate association with risk factors, we subclassified surgeries into 5 groups: 1, arthroplasty/non-arthroplasty; 2, primary/revision; 3, elective/urgent; 4, oncologic/non-oncologic; 5, preoperative/postoperative filter. RESULTS: Mechanical complications were 16% and required a filter revision. Sixty-four percent of the revised VCFs developed a mechanical failure and could not be retrieved. Overall prevalence of TED recurrence, post-thrombotic syndrome and hemorrhage was 33%, 15% and 4.5%, respectively. Spinal surgeries were a risk factor for developing TED recurrences. Only 4% of patients died of a TED recurrence. CONCLUSIONS: Orthopaedic procedures had a high risk of mechanical and hematologic complications after using a retrievable VCF. However, mortality was low due to these complications.

Despite its prevalence, it is usually underdiagnosed. Objective to assess frequency of CAN in type 2 diabetes, treated at the Diabetology Service at Cordoba Hospital, Argentina. Method: Cross-sectional study was conducted from May 2015 to May 2016. Cardiovascular Autonomic Tests (Ewing's battery) were performed: response to Valsalva maneuver, expiration-to-inspiration ratio (E/I ratio), standing to lying flat and postural hypotension. Results: 100 type 2 diabetes patients, 53% females. The mean age and diabetes duration 52 years old and 8.4 years, respectively. Hemoglobin A1c level of 8.7% and 47% were insulin-requiring type 2 diabetes patients. 29% had early CAN, 54% confirmed CAN (10% severe CAN) and 17% normal cardiovascular tests. Confirmed CAN was higher in those with longer duration of diabetes; longer duration of insulin therapy, older patients and severe hypoglycemia events was higher in those with confirmed CAN versus without CAN or early CAN (p 0.003). The risk factors associated were hypertension OR 2.55 (p 0.02), peripheral neuropathy OR 11.7 (p <0.0001), diabetic retinopathy OR 9.03 (p 0.001), diabetic nephropathy OR 3.12 (p 0.03) and hemoglobin A1c > 7% OR 2.57 (p 0, 03). Conclusions: frequency of CAN was high, was associated with hypertension, microvascular complications, older age, poor metabolic control, longer duration of disease and insulin therapy. Patients with a higher risk of developing CAN should be identified, in order to reduce the impact of this complication.

Filamentous fungi have an uncertain place within the statistics, since in our media data regarding their prevalence, causal agents and outcome of those who suffer them remain scarce. The aim of this study was to evaluate the prevalence of fungal infection by filamentous fungi (IHF) in patients hospitalized in burn intensive care unit (BICU), and to review clinical, epidemiological, microbiological and evolutionary characteristics of these patients and to know the frequency and distribution of the isolated fungi. Materials and methods: Retrospective and descriptive study. It includes all individuals admitted in burns intensive care unit (2012-2015), with positive culture for filamentous fungi in skin biopsies and bedsores. Results: A total of 168 patients were admitted in the BICU in a period of 3 years. 90% were major burned and 17% of them developed IHF (29/168). Aspergillus spp (24%), Fusarium sp (14%), Mucor spp (3%) and various black fungus genera (58%) were the main genera found in cultives. About 24% of the patients with IHF died and Fusarium spp was found in 50% of the cases. The cause of death was irreversible cardiogenic shock with multiorgan failure. Conclusions: Filamentous fungal infection was present in 17% of burned patients. The main isolatte fungi in samples were dematiaceous mould. Mortality among patients was 24%, with Fusarium being the fungus found in the highest number of deaths (50%).

Hepatic parasitosis is an infrequent etiological cause of benign solid liver tumors. Objective. To present the case of a patient with benign solid liver tumors treated with right portal vein embolization and, later, with hepatectomy. Clinical case. 60-year-old, male patient diagnosed with multiple solid liver tumors, due to a generalized case of jaundice. The decision to perform surgery was made on the basis of the clinical symptoms and the impossibility of discarding malignancy through complementary tests. Before surgery, hepatic volumetry and right portal vein embolization were done to increase future hepatic remnant. Right hepatectomy and hepatic resection of segment IVa were performed. The patient evolved positively from jaundice and the anatomopathological results showed a lesion related to hepatic parasitosis. Conclusion. In the presence of a solid liver tumor, it is necessary to rule out the malignant etiology of the lesion. If this is not possible, or if the patient continues with the symptomatology, surgical resection is prescribed, taking into account the volume of the hepatic gland and future hepatic remnant.

Renal involvement may occur in up to 30% of patients. The incidence of tubulopathies ranges from 2.6 to 33%. They are manifested by defects in the urine concentration and hydroelectrolyte alterations, mainly distal tubular acidosis and exceptionally proximal tubular acidosis. These disorders can be associated with nephrocalcinosis and renal lithiasis.We report the case of a patient with primary Sjogren who presented proximal renal tubular acidosis associated with recurrent renal colic due to renal lithiasis and nephrocalcinosis.We highlight the importance of diagnosing renal tubular acidosis in patients with Sjogren's syndrome that present alterations in urinary sediment and electrolyte disorders to avoid nephrocalcinosis and nephrolithiasis. Acidosis correction treatment aims to prevent the progression of the disorder and preserve renal function.

AB - Background: Sexual behaviour of young people is one of the major public health issues. This is because adolescent people may involve themselves in risky sexual behaviour such as practising sex at an early age, having multiple sexual partners, having sex while under the influence of alcohol or drugs, and unprotected sexual behaviours. The objective of this study was to explore the premarital sexual behaviours among higher secondary school students in Pokhara Sub-Metropolitan City. Methods: This survey adopted a design of an institution based descriptive cross-sectional study. A pre-tested structured questionnaire sealed in an envelope was distributed among all consenting 522 higher secondary school adolescent students. Results: Nearly twenty-five per cent (24.6%) of study respondents have had premarital sex. Respondents who had discussed sexual matters with friends had a 2.62-fold higher chance of having premarital sex than those who had not. Male respondents were eight-fold more likely to have premarital sex than females. Respondents who were exposed to pornography reported a nine-fold higher possibility of having premarital sex. Study respondents were also involved in unsafe sexual practices; for example, 13.4% of male respondents had sex with female sex workers. Conclusion: Despite the deleterious social and cultural norms and values regarding premarital sexual activities school adolescents are increasingly involved in sexual activities before marriage. Peer groups or friends are major sources of sexual and reproductive health information, which is often insufficient and inaccurate. It is important to design an appropriate and effective intervention to ensure that adolescents get correct and suitable sexual and reproductive information. PMID- 30273543 TI - Salvianolic acid B attenuates experimental pulmonary inflammation by protecting endothelial cells against oxidative stress injury. AB - Endothelial cell injury and subsequent inflammation play pivotal roles in the pathogenesis of pulmonary fibrosis, a progressive and fatal disorder. We found previously that salvianolic acid B (SAB) attenuated experimental pulmonary fibrosis. Pulmonary fibrosis is driven by inflammation, but the anti-inflammatory role and mechanism of SAB on the treatment of pulmonary fibrosis is still unknown. Here, our in vivo studies showed that SAB had a strong anti-inflammatory effect on bleomycin-instilled mice by inhibiting inflammatory cell infiltration and inflammatory cytokine production. Moreover, SAB protected endothelial cells against oxidative stress injury and inhibited endothelial cell apoptosis in bleomycin-treated mice. The in vitro studies also showed that SAB decreased the H2O2-induced overproduction of reactive oxygen species to protect EA.hy926 endothelial cells from oxidative damage, and further inhibited H2O2-induced permeability and overexpression of pro-inflammatory molecules. The next studies revealed that SAB inhibited the H2O2-induced cell apoptosis and attenuated the decrease of tight junction-related gene expression, resulting in a decrease of the endothelial permeability in injured endothelial cells. Furthermore, Western blot analysis suggested that SAB decreased endothelial cell permeability and expression of pro-inflammatory cytokines by inhibiting MAPK and NF-kappaB signaling pathways. Taken together, these data indicate that SAB exerted anti inflammatory roles in pulmonary fibrosis by protection of the endothelial cells against oxidative stress injury, mediated by inhibition of endothelial permeability and expression of pro-inflammatory cytokine via the MAPK and NF kappaB signaling pathways. PMID- 30273544 TI - Histone deacetylase 6 regulated expression of IL-8 is involved in the doxorubicin (Dox) resistance of osteosarcoma cells via modulating ABCB1 transcription. AB - Emerging evidence shows that cytokines such as interleukins (ILs) are involved in the progression and chemoresistance of multiple tumors, including osteosarcoma (OS). Our present study established the doxorubicin (Dox) resistant human OS MG 63 and HOS cells and named them MG-63/Dox and HOS/Dox, respectively. The expression of IL-8, while not VEGFA, IL-32, or IL-34, was significantly increased in OS/Dox cells as compared with that in the parental cells. IL-8 neutralization antibody can significantly increase the Dox sensitivity of OS/Dox cells. Further, IL-8 can up regulate ABCB1, which encodes one important ATP-binding cassette (ABC) transporter /P-glycoprotein (P-gp). Mechanically, IL-8 increased the transcription of ABCB1 via up regulating its promoter activity, while had no effect on its protein or mRNA stability. Targeted inhibition of p65 can attenuate IL-8 induced transcription of ABCB1 in OS cells. Treatment OS cells with 5-aza dC, the inhibitor of DNMT, had no effect on expression of IL-8. Expression of HDAC6 in MG-63/Dox and HOS/Dox cells was significantly greater than that in their parental cells. Knockdown of HDAC6 can suppress the expression of IL-8 in OS cells. Collectively, our data showed that HDAC6 mediated upregulation of IL-8 can regulate the Dox sensitivity of OS cells via transcriptionally regulating the expression of ABCB1. Targeted inhibition of IL-8 might be a potent potential approach for overcome the Dox resistance of OS cells and helpful for clinical therapy of OS patients.

PMID- 30273546 TI - Physicochemical characterization of 6-O-acyl trehalose fatty acid monoesters in desiccated system. AB - The understanding of the basic physicochemical properties of trehalose lipid is indispensable to extending their availability. In this study, the hydrate crystal (Cr), the liquid crystalline (LC) phase and the glassy state formations of 6-O acyl trehalose fatty acid monoester (TREn) were examined under in a desiccated system. TREn (n = 10, 12, 14, 16) formed monohydrate Cr and showed the hydrate Cr glassy fluid lamellar LC (Lalpha) phase transition via dehydration in the heating process. Here, Lalpha phase for TRE10 and TRE12 was kinetically formed by the dehydration below the glass transition temperature (Tg). On the dehydration temperature (Tdeh), Tgs, and heat capacity changes (DeltaCps) at these Tgs, no distinct effects by the difference of the acyl chain length were recognized, possibly because the core structure of containing sugar hydrate Cr or sugar moieties should be similar regardless of the acyl chain length. Besides, TRE10 having a relatively high hydrophilic/hydrophobic balance (HLB) afforded to form the cubic LC (Q) phase and the corresponding glassy phase, while TRE14 and TRE16 having low HLB afforded the Lalpha phase as well as the corresponding glassy phases above Tg. TRE12 having middle HLB afforded both LCs and the corresponding glassy phase by controlling the kinetics of LC-LC phase transition between Lalpha and Q phases. Furthermore, the anomalous reversible phase transition during both the heating and cooling processes was also ascertained in the glassy phase for TRE16, which was considered the phase transition between glassy Lalpha and glassy lamellar gel (Lbeta) phase. It greatly empathizes the two-dimensional trehalose glass layer and fluid hydrocarbon chains in the TREn glassy phase. Thus, in this study, it was demonstrated that TREn as the simplest trehalose lipid exhibited the glassy formation performance as well as the hydrate Cr formation, which showed less chain length dependence, together with the LC formation and the phase transition between glassy Lalpha and glassy Lbeta phase, which depended on chain length greatly. PMID- 30273547 TI - The Clinical Application of Recombinant Human Bone Morphogenetic Protein 7 for Reconstruction of Alveolar Cleft: 10 Years' Follow-Up. AB - PURPOSE: The purpose of this study was to report on a 10-year assessment after the application of recombinant human bone morphogenetic protein 7 (rhBMP-7) for the reconstruction of alveolar clefts. PATIENTS AND METHODS: This study was conducted as a prospective phase II clinical trial on 9 unilateral and 2 bilateral alveolar clefts that received rhBMP-7 (Osigraft; Stryker Biotech, UK). The mean age of the patients at surgery was 10.4 years. At 6 months postoperatively, occlusal radiographs were taken to evaluate bone formation at the cleft site. Patients were followed within the routine cleft care pathway for 10 years to monitor the impact of bone morphogenetic protein 7 on orthodontic treatments and maxillary growth. Radiographs were taken according to the standard cleft care protocol. RESULTS: The radiographic assessment of the unilateral cleft lip and palate cases suggested good bone formation with a Kindelan score of grade 1 or 2. The bilateral alveolar cleft cases had a score of grade 3 or 4, indicating failure or partial failure. The children with successful grafts underwent a routine orthodontic follow-up without incident. The maxillary growth appeared to be similar to that in cases grafted with autogenous bone. No long term complications and no abnormal pattern of bone formation were detected. CONCLUSIONS: The study provides unique evidence on the long-term safety of rhBMP 7 when applied at the area of skeletal immaturity for the reconstruction of alveolar clefts in children.

PMID- 30273549 TI - Economic Evaluation of Activities of Daily Living Retraining During Posttraumatic Amnesia for Inpatient Rehabilitation Following Severe Traumatic Brain Injury. AB - OBJECTIVE: To evaluate the cost-effectiveness of structured activities of daily living (ADL) retraining during posttraumatic amnesia (PTA) plus treatment as usual (TAU) vs TAU alone for inpatient rehabilitation following severe traumatic brain injury (TBI). DESIGN: Trial-based economic evaluation from a health-system perspective. SETTING: Inpatient rehabilitation center. PARTICIPANTS: Participants (N=104) admitted to rehabilitation and in PTA for >7 days following severe TBI. INTERVENTIONS: Structured ADL retraining during PTA plus TAU vs TAU alone. Structured ADL retraining was manualized to minimize the risk of agitation and maximize functional improvement, following principles of errorless and procedural learning and targeting individualized therapy goals. TAU included physiotherapy and/or speech therapy during PTA plus ADL retraining after PTA emergence. MAIN OUTCOME MEASURES: FIM total scores at baseline, PTA emergence, hospital discharge, or final follow-up (2mo postdischarge) where FIM total scores were calculated as the sum of 5 FIM motor self-care items and a FIM meal-preparation item. RESULTS: Structured ADL retraining during PTA significantly increased functional independence at PTA emergence (mean difference: 4.90, SE: 1.4, 95% confidence interval [CI]: 1.5, 8.3) and hospital discharge (mean difference: 5.22, SE: 1.4, 95% CI: 1.8, 8.7). Even in our most pessimistic scenario, structured ADL retraining was cost-saving as compared to TAU (mean: -$7762; 95% CI: -$8105, -$7419). Together, these results imply that structured ADL retraining dominates (less costly but no less effective) TAU when effectiveness is evaluated at PTA emergence and hospital discharge. CONCLUSIONS: Structured ADL retraining during PTA yields net cost-savings to the health system and offers a cost effective means of increasing functional independence at PTA emergence and hospital discharge. PMID- 30273550 TI - Neuroprotective effects of MHY908, a PPAR alpha/gamma dual agonist, in a MPTP induced Parkinson's disease model. AB - Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors and are considered promising therapeutic targets in several neurodegenerative diseases. A number of PPAR agonists have been shown to have neuroprotective properties in the presence of oxidative stress, neuroinflammatory response, and apoptosis in various neurodegenerative disease. MHY908 is a novel PPAR alpha/gamma dual agonist, which has been shown to suppress inflammatory response and attenuate insulin resistance in aged rats and db/db mice. Here, we evaluated the neuroprotective effects of MHY908 in a 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine (MPTP)-induced mouse model of PD. Pretreatment with MHY908 attenuated MPTP-induced dopaminergic neuronal loss and motor deficit. MPTP induced glial activations were mitigated by MHY908 in the nigrostriatal pathway, and MHY908 effectively blocked 1-methyl-4-phenylpyridinium (MPP+)-induced cell death and ROS production in SH-SY5Y neuroblastoma cells. Further study revealed MHY908 inhibited MPP+-induced astroglial activation by suppressing NF-kappaB signaling in primary astrocytes. Taken together, the present study suggests that PPAR alpha/gamma dual agonists be considered potentially useful preventions for PD and other neurodegenerative diseases associated with neuroinflammation. PMID- 30273551 TI - TRPM2 confers susceptibility to social stress but is essential for behavioral flexibility. AB - Transient receptor potential melastatin 2 (TRPM2) is a Ca2+-permeable, nonselective cation channel and a member of the TRP channel superfamily that acts as a sensor of intracellular redox states. TRPM2 is widely distributed in many tissues and highly expressed in the brain, but the physiological roles of TRPM2 in the central nervous system remain unclear. In this study, TRPM2-deficient mice were examined in a series of behavioral tests. TRPM2-deficient mice did not significantly differ from wild-type littermates in muscle strength, light/dark transition test, rotarod, elevated plus maze, social interaction, prepulse inhibition, Y-maze, forced swim test, cued and contextual fear conditioning, and tail suspension test. In the Barnes circular maze, TRPM2-deficient mice learned the fixed escape box position at similar extent to wild-type littermates, suggesting normal reference memory. However, performance of the first reversal trial and probe test were significantly impaired in TRPM2-deficient mice. In the T-maze delayed alternation task, TRPM2 deficiency significantly reduced choice accuracy. These results indicate that TRPM2-deficient mice shows behavioral inflexibility. Meanwhile, social avoidance induced by repeated social defeat stress was significantly attenuated in TRPM2-deficient mice, suggesting that TRPM2 deficiency confers stress resiliency. Our findings indicate that TRPM2 plays an essential role in maintaining behavioral flexibility but it increases susceptibility to stress. PMID- 30273552 TI - Alzheimer's disease (AD) therapeutics - 2: Beyond amyloid - Re-defining AD and its causality to discover effective therapeutics. AB - Compounds targeted for the treatment of Alzheimer's Disease (AD) have consistently failed in clinical trials despite evidence for target engagement and pharmacodynamic activity. This questions the relevance of compounds acting at current AD drug targets - the majority of which reflect the seminal amyloid and, to a far lesser extent, tau hypotheses - and limitations in understanding AD causality as distinct from general dementia. The preeminence of amyloid and tau led to many alternative approaches to AD therapeutics being ignored or underfunded to the extent that their causal versus contributory role in AD remains unknown. These include: neuronal network dysfunction; cerebrovascular disease; chronic, local or systemic inflammation involving the innate immune system; infectious agents including herpes virus and prion proteins; neurotoxic protein accumulation associated with sleep deprivation, circadian rhythm and glymphatic/meningeal lymphatic system and blood-brain-barrier dysfunction; metabolic related diseases including diabetes, obesity hypertension and hypocholesterolemia; mitochondrial dysfunction and environmental factors. As AD has become increasingly recognized as a multifactorial syndrome, a single treatment paradigm is unlikely to work in all patients. However, the biomarkers required to diagnose patients and parse them into mechanism/disease-based sub groups remain rudimentary and unvalidated as do non-amyloid, non-tau translational animal models. The social and economic impact of AD is also discussed in the context of new FDA regulatory draft guidance and a proposed biomarker-based Framework (re)-defining AD and its stages as part of the larger landscape of treating dementia via the 2013 G8 initiative to identify a disease modifying therapy for dementia/AD by 2025. PMID- 30273553 TI - Alzheimer's disease (AD) therapeutics - 1: Repeated clinical failures continue to question the amyloid hypothesis of AD and the current understanding of AD causality. AB - Deposits of amyloid plaques and neurofibrillary tangles of aggregated tau in the brain represent key hallmarks of the neurodegenerative disorder, Alzheimer's Disease (AD) and form the basis of the major hypotheses of AD causality. To date, therapeutics that reduce brain amyloid in AD patients have demonstrated no effect in reversing the associated decline in cognition or function indicating that the amyloid hypothesis is either incorrect or that there is a point when the disease becomes independent of Abeta production or is refractory to any type of therapeutic intervention. The clinical failures of inhibitors of tau aggregation, neurotransmitter modulators and drugs repurposed from AD-associated disease indications tend to support this latter viewpoint. Current understanding of AD causality is thus incomplete, a situation that has been compounded by a debate on whether AD is a singularly distinct form of dementia and by the dogmatic promotion of hypotheses over actual clinical data. The latter has repeatedly led to compounds lacking efficacy in Phase II trials being advanced into Phase III where their lack of efficacy is routinely recapitulated. This Commentary, the first of two, discusses amyloid and tau as putative drug targets for AD in the context of the prevalence and economic and social impact of this insidious neurodegenerative disease. PMID- 30273554 TI - How much starvation, desiccation and oxygen depletion can Drosophila melanogaster tolerate before its upper thermal limits are affected? AB - Heat tolerance is commonly assessed as the critical thermal maximum (CTmax) using the dynamic method exposing organisms to a gradually increasing (ramping) temperature until organisms fall into a coma. The CTmax estimate is dependent on the ramping rate, with decreased rates leading to longer treatments and ultimately lower CTmax estimates. There is a current discussion surrounding the physiological dynamics of the effect of the time of exposure by temperature interaction on these estimates. Besides temperature the time of exposure to limited food (starvation), desiccation, and reduced levels of oxygen or increased levels of CO2 may, in interaction with ramping rate, act as confounding factors when assessing upper thermal limits using the dynamic method. Here we test the role of the different potentially confounding factors for assaying thermal tolerance using a ramping assay under four different ramping rates, varying from 0.01 degrees C/min to 0.2 degrees C/min. We find that CTmax values are higher at faster ramping rates and that oxygen or CO2 concentration does not show any negative effect on the CTmax values obtained within the experimental pre treatment period (32 h). Both water (up to 6 h) and food (up to 42 h) deprivation prior to assay showed a negative correlation with thermal tolerance of the flies. For both traits, we found a significant interaction with ramping rate, most likely due to prolonged assays at lower rates. However, as little water was lost during the ramping assay and as food deprivation only modestly affected CTmax values, results were very robust to the conditions experienced during the assay (even at slow rates) and mainly affected by the conditions experienced prior to performing the assay. Thus, for the most commonly applied experimental conditions CTmax estimates are unlikely to be biased or confounded by ramping rate, starvation, desiccation or deteriorating atmospheric composition. PMID- 30273555 TI - Pilot Tobacco Treatment Intervention for Women in Residential Treatment for Substance Use Disorder. AB - OBJECTIVE: To test the feasibility, acceptability, and efficacy of Get Fit and Quit (GFAQ), a community-engaged, holistic tobacco treatment program for women of childbearing age in a residential substance use disorder treatment facility. DESIGN: A quasi-experimental, one-group, longitudinal design. SETTING: A local Young Men's Christian Association (YMCA) location. PARTICIPANTS: Twenty-three women of childbearing age were enrolled in the study. Nearly all (21/23) participants were White, and most were nonpartnered and unemployed. More than one third of participants had more than high school educations, and five (22%) were pregnant at enrollment. METHODS: The program was conducted in 10 sessions over 6 months. For each 90-minute session, approximately 45 minutes were dedicated to smoking cessation, and 45 minutes were dedicated to group physical activity. Means and 95% confidence intervals were used to summarize nicotine dependence, expired carbon monoxide, urine cotinine, and exercise self-efficacy at baseline and 5-week, 8-week, and 6-month assessments. Cigarettes smoked per day were summarized using medians and interquartile ranges over time. Program satisfaction and regular exercise were presented as percentages with 95% confidence intervals. RESULTS: Of the 23 women who enrolled in GFAQ, 7 (30%) completed the program. Compared with baseline results, participants who completed GFAQ had lower nicotine dependence and smoked fewer cigarettes per day. Additionally, at 5 weeks, more GFAQ participants exercised regularly (64%) compared with baseline (14%). Most participants viewed the program favorably. CONCLUSION: Smoking in women of childbearing age with substance use disorders is an important public health issue. GFAQ is a promising intervention for tobacco treatment for this high-risk population, although the number of initial participants who completed the program was low. PMID- 30273556 TI - A highly selective and sensitive fluorescent sensor for relay recognition of Zn2+ and HSO4-/H2PO4- with "on-off" fluorescent responses. AB - A simple and effective fluorescent sensor bearing pyridine units was designed and synthesized. The sensor can detect Zn2+ with high selectivity accompanied by a distinct fluorescence turn-on response, inducing the fluorescent color markedly changed from darkness to bright green. The limit of detection (LOD) was calculated as 8.56 * 10-9 M with a good linearity (R = 0.95943). In addition, the chelate of sensor with Zn2+ can further recognize H2PO4-/HSO4- with notable fluorescence quenching behaviors over other anions and the LODs were as low as 3.44 * 10-6 M (R = 0.99762) and 3.84 * 10-6 M (R = 0.99315), respectively. PMID- 30273557 TI - Development and characterization of sandwich-type enzyme-linked aptamer assay for the detection of rongalite in food. AB - Rongalite is an essentially strong carcinogen, which due to its properties as a bleaching and brightening, is illegally added to the food processing. In this study, a sandwich-type enzyme-linked aptamer assay (ELAA) is developed by using a rongalite-specific aptamer G02 modified fluorescein amidite (FAM) as a capture probe and aptamer C01 modified biotin as a signal element. In the presence of rongalite, the aptamer G02-rongalite-aptamer C01 complex is produced, and the absorbance value can be subsequently measured. The sandwich-type ELAA was shown to detect rongalite with high specificity and affinity, with a KD value of 19.91 +/- 1.321 nM. In addition, the standard curve was established, with the limit of quantification (LOQ) for rongalite at 10 ng mL-1. By calculating the slope of the standard curve and the standard deviation of the blank values, the method detection limit (MDL) was 0.572 ng mL-1. Additionally, the accuracy of the sandwich-type ELAA was demonstrated in real food samples. Compared with high pressure liquid chromatography (HPLC) assay, the sandwich-type ELAA can detect rongalite directly, and it has great advantages in pre-treatment, operation technique and cost. In short, our data suggest that the sandwich-type ELAA may be applicable as a molecular detection technique for rongalite. PMID- 30273558 TI - Distinct patterns of atrial electrical and structural remodeling in angiotensin II mediated atrial fibrillation. AB - Atrial fibrillation (AF) is prevalent in hypertension and elevated angiotensin II (Ang II); however, the mechanisms by which Ang II leads to AF are poorly understood. Here, we investigated the basis for this in mice treated with Ang II or saline for 3 weeks. Ang II treatment increased susceptibility to AF compared to saline controls in association with increases in P wave duration and atrial effective refractory period, as well as reductions in right and left atrial conduction velocity. Patch-clamp studies demonstrate that action potential (AP) duration was prolonged in right atrial myocytes from Ang II treated mice in association with a reduction in repolarizing K+ currents. In contrast, APs in left atrial myocytes from Ang II treated mice showed reductions in upstroke velocity and overshoot, as well as greater prolongations in AP duration. Ang II reduced Na+ current (INa) in the left, but not the right atrium. This reduction in INa was reversible following inhibition of protein kinase C (PKC) and PKCalpha expression was increased selectively in the left atrium in Ang II treated mice. The transient outward K+ current (Ito) showed larger reductions in the left atrium in association with a shift in the voltage dependence of activation. Finally, Ang II caused fibrosis throughout the atria in association with changes in collagen expression and regulators of the extracellular matrix. This study demonstrates that hypertension and elevated Ang II cause distinct patterns of electrical and structural remodeling in the right and left atria that collectively create a substrate for AF. PMID- 30273559 TI - Epithelial RNase H2 Maintains Genome Integrity and Prevents Intestinal Tumorigenesis in Mice. AB - BACKGROUND & AIMS: RNase H2 is a holoenzyme, composed of 3 subunits (ribonuclease H2 subunits A, B, and C), that cleaves RNA:DNA hybrids and removes mis incorporated ribonucleotides from genomic DNA through ribonucleotide excision repair. Ribonucleotide incorporation by eukaryotic DNA polymerases occurs during every round of genome duplication and produces the most frequent type of naturally occurring DNA lesion. We investigated whether intestinal epithelial proliferation requires RNase H2 function and whether RNase H2 activity is disrupted during intestinal carcinogenesis. METHODS: We generated mice with epithelial-specific deletion of ribonuclease H2 subunit B (H2bDeltaIEC) and mice that also had deletion of tumor-suppressor protein p53 (H2b/p53DeltaIEC); we compared phenotypes with those of littermate H2bfl/fl or H2b/p53fl/fl (control) mice at young and old ages. Intestinal tissues were collected and analyzed by histology. We isolated epithelial cells, generated intestinal organoids, and performed RNA sequence analyses. Mutation signatures of spontaneous tumors from H2b/p53DeltaIEC mice were characterized by exome sequencing. We collected colorectal tumor specimens from 467 patients, measured levels of ribonuclease H2 subunit B, and associated these with patient survival times and transcriptome data. RESULTS: The H2bDeltaIEC mice had DNA damage to intestinal epithelial cells and proliferative exhaustion of the intestinal stem cell compartment compared with controls and H2b/p53DeltaIEC mice. However, H2b/p53DeltaIEC mice spontaneously developed small intestine and colon carcinomas. DNA from these tumors contained T>G base substitutions at GTG trinucleotides. Analyses of transcriptomes of human colorectal tumors associated lower levels of RNase H2 with shorter survival times. CONCLUSIONS: In analyses of mice with disruption of the ribonuclease H2 subunit B gene and colorectal tumors from patients, we provide evidence that RNase H2 functions as a colorectal tumor suppressor.

This report describes progress on a physiologically based transport model relating sweat glucose and key electrolyte concentrations to those in blood. Iontophoretically stimulated sweat glucose and fasted blood glucose were simultaneously measured in 2 healthy human subjects. Sweat glucose was measured with a novel, prototype skin sweat collection/analysis system and blood glucose with a commercial fingerstick glucometer. These data, in combination with data from 3 published studies, were used to calibrate a dynamic mathematical model for glucose transport and uptake in human skin, followed by extraction into sweat. Model simulations revealed that experimental and literature sweat glucose values were well represented under varying physiologic conditions. The glucose model, calibrated under a variety of experimental conditions including electrical enhancement, revealed a 10 min blood to-sweat lag time and a sweat/blood glucose level ranging from 0.001 to 0.02, depending on the sweat rate. These values are consistent with those reported in the literature. The developed model satisfactorily described the sweat-to-blood relationship for glucose concentrations measured under different conditions in 4 human studies including the present pilot study. The algorithm may be used to facilitate sweat biosensor development. PMID- 30273560 TI - Increased sleep time and reduced energy expenditure contribute to obesity after ovariectomy and a high fat diet. AB - In this study we examined if sleep time, caloric intake and energy expenditure are important contributors to development of ovariectomy-induced obesity in mice fed control or high fat diet (HFD). Twelve female mice at 6 weeks of age were divided into 2 groups: Sham (n = 5) and ovariectomized (OVX, n = 7). Mice were fed control diet for 9 weeks and shifted to HFD for additional 9 weeks. Food intake and body weight were measured daily and body composition was measured weekly by EchoMRI. Energy expenditure (EE), oxygen consumption (VO2), motor activity (MA) and sleep time were monitored at week 9 during control diet and HFD. OVX did not alter caloric intake, body weight or body composition, MA, sleep time or fasting blood glucose, but slightly reduced EE compared to Sham mice on control diet. After HFD feeding, OXV mice had similar caloric intake, lean mass, MA, and blood glucose levels but had significantly greater weight gain (8.2 +/- 1.0 vs. 4.8 +/- 1.2 g, p < 0.05), increased fat mass and sleep time, and reduced EE (3.3 +/- 0.4 vs. 5.5 +/- 0.2 kcal/h) and VO2 (1.12 +/- 0.01 vs. 1.83 +/- 0.05 ml/min) compared to Sham group. Daytime blood pressure was higher while nighttime heart rate was lower in OVX group. These results suggest that OVX may not substantially alter body weight or body composition in mice fed a normal diet, but when combined with HFD it increases sleep time and reduces EE, leading to greater weight gain and adiposity without altering food intake. PMID- 30273562 TI - Gene expression profile of cytokines produced in biopsies from patients with American cutaneous leishmaniasis. AB - American cutaneous leishmaniasis (ACL) causes a local inflammatory process, inducing expression of several cytokine genes. Particularly, IFN-gamma can predict to disease susceptibility. Based in these data, this study was aimed to investigate the gene expression profile of IFN-gamma, IL-10, IL-27, TNF-gamma, TGF-beta and IL-6 produced in biopsies from ACL patients; and whether the gene expression profile of IFN-gamma could determine the disease evolution. Gene expression of 6 cytokines was investigated in 40 formalin-fixed paraffin embedded (FFPE) biopsies from patients with cutaneous leishmaniosis (CL); and 10 FFPE biopsies from patients with mucosal leishmaniasis (ML) (control). All 50 patients were infected with Leishmania (Viannia) braziliensis. Gene expression was determined by qPCR; and a normal control group was used for calculations (5 normal biopsies). Values were expressed as Relative Quantification (RQ). The 40 CL patients were classified into 2 groups. CLlowIFN-gamma, 35 patients with RQ for IFN-gamma below 100; and CLhighIFN-gamma, 5 (12.5%) patients with RQ above 100. Significant increase of mRNA levels of IFN-gamma, IL-10 and IL-27 was shown in CLhighIFN-gamma group when compared with CLlowIFN-gamma and ML groups. TNF alpha levels in CLlowIFN-gamma group were higher than CLhighIFN-gamma and ML groups. TGF-beta and IL-6 were similar in 3 groups. Comparison of cytokine expression/group showed that CLlowIFN-gamma group had an equilibrium between the cytokines analyzed. In ML group, IFN-gamma was over-expressed; but in CLhighIFN gamma group, besides IFN-gamma, IL-27 was also over-expressed. The immune response to Leishmania induces to identification of some markers, which can be determined by analysis by gene expression of cytokines produced in biopsies. PMID- 30273563 TI - Echinostoma revolutum: Development of a high performance DNA-specific primer to demonstrate the epidemiological situations of their intermediate hosts. AB - Echinostomiasis caused by the Echinostoma group, in particular E. revolutum are a significant problem for both humans and other animals. This group has a large number of morphological similarities that are difficult and time-consuming to identify. The present study aimed to develop high-performance tools for the detection of the prevalence of E. revolutum and to reveal the prevalence of E. revolutum infections in intermediate snail hosts in Lopburi province, Thailand. The snail specimens were collected by stratified sampling method and examined to collect trematodes in the larval stage. The specific primer was manually designed and based on 18 s rDNA and verified the specificity and sensitivity for use as an identification tool to compare with classical method, constructed by epidemic mapping. The overall prevalence value of E. revolutum was found to be 16.26%. Tha Luang district had the highest prevalence (70.14%), followed by Chai Badan, Phatthana Nikhom, Tha Wung, Ban Mi, Khok Samrong, Nong Muang and Sa Bot at 42%, 25.14%, 2.52%, 1.73%, 2%, 1.33% and 0.40%, respectively. With regard to the specific primer, it can amplify both cercarial and metacercarial DNA (90 pg/MUl.) and discriminated E. revolutum from its hosts, other trematodes and other echinostome larvae with no cross-reactions. Therefore, the developed specific primer can be used as a species-specific identification tool with a high degree of sensitivity and specificity. Consequently, this data is important for monitoring the outbreak of E. revolutum. It can be applied for initiating surveillance programs of snail-borne diseases in both medical and veterinary studies. PMID- 30273564 TI - Titanium dioxide nanoparticles induce proteostasis disruption and autophagy in human trophoblast cells. AB - Titanium dioxide nanoparticles (TiO2 NPs) exist in many nano-products and concerns have been raised about their potential toxicity on human beings. One such issue is their potential effects on placental function, and the studies on this topic are limited and the mechanism remains unclear. Here we employed human trophoblast HTR-8/SVneo cells to investigate the effects of TiO2 NPs on trophoblast. Results showed that TiO2 NPs could enter cells and were mostly distributed in lysosomes, with some in the cytoplasm. TiO2 NPs and protein aggregation were found in both fetal bovine serum (FBS) in culture medium and cytoplasm of HTR-8/SVneo cells. In consistence with that, proteostasis of HTR 8/SVneo cells was significantly disrupted and endoplasmic reticulum (ER) stress related markers including PERK, IRE1-alpha were increased. After high speed centrifugation, the proteins PERK and IRE1-alpha were dramatically decreased in the highest TiO2 NPs treatment group, which indicated interactions between TiO2 NPs and these two proteins. Meanwhile, the protein expressions of LC3-II/LC3-I and P62, the autophagy biomarkers, were increased and the autophagy flux was not blocked. Cellular ROS stress increased and mitophagy related genes including PINK and Parkin increased along with the increased co-localization of LC3 and mitochondria. Taken together, these results indicated that TiO2 NPs interacted with intracellular proteins and activated ER stress and mitophagy in HTR-8/SVneo cells, which might do damage to placental function. PMID- 30273565 TI - Investigation of genotoxic and apoptotic effects of zirconium oxide nanoparticles (20 nm) on L929 mouse fibroblast cell line. AB - In recent years, advances in nano-scale technology have led to the use of nanoparticles in almost all areas of life. Nanoparticles (NP) have been acknowledged as one of the emerging environmental threats; however, studies in different components of environment are limited. Among the available nanoparticles, zirconium oxide nanoparticles are widely used in tooth coating and cosmetic products. In this study, three different concentrations of 20 nM Zirconium Oxide nanoparticles were used to investigate the genotoxic and apoptotic effects in vitro conditions by single cell gel electrophoresis (Comet) and flow cytometry methods on L929 Mouse Fibroblast cell line. In this study, we aimed to decipher whether Zirconium Oxide nanoparticles had genotoxic and apoptotic effects on fibroblast cells or not. The relationship between the apoptotic effect and the genotoxic effect was examined. Three different concentrations (50 MUg/ml, 100 MUg/ml and 150 MUg/ml) of 20 nM Zirconium Oxide nanoparticles were used on L929 cells in order to determine the relationship between apoptotic and genotoxic parameters. Our results support that Zirconium Oxide nanoparticles induced DNA damage and apoptosis at all used concentrations. In vivo studies are currently conducted to further evaluate the cytotoxic effect of these nanoparticles. PMID- 30273566 TI - Salinomycin suppresses cancer cell stemness and attenuates TGF-beta-induced epithelial-mesenchymal transition of renal cell carcinoma cells. AB - Metastatic Renal cell carcinoma (RCC) remains a difficult oncologic challenge. Salinomycin is a monocarboxylic polyether antibiotic, which has been proved to possess anti-tumor activities in multiple types of cancer cells. However, its effects on RCC cells remains unclear. In our study, salinomycin could inhibit the proliferation and viability of RCC cell lines 786-O and ACHN. The TUNEL assay revealed that treatment with salinomycin induced DNA breaking in RCC cells. Consistently, Western blotting showed up-regulation of pro-apoptotic biomarkers (cleaved caspase3/9 and cleaved PARP1) and down-regulation of anti-apoptotic biomarker (survivin) in RCC cells after salinomycin treatment, suggesting that salinomycin could induce RCC cell apoptosis. salinomycin treatment also suppressed the sphere formation ability of RCC cells and decreased the expressions of CD105, ALDH1 and CD44, biomarkers for reflecting the stemness of RCC cells. salinomycin treatment effectively down-regulated SMO and Gli1, two key proteins in Hedghog signaling pathway, in a dose-dependent manner. Moreover, salinomycin could suppress the invasion and migration of RCC cells in the presence of TGF-beta1, as observed in wound-healing and Transwell assays. salinomycin treatment attenuated TGF-beta1-induced epithelial-mesenchymal transition (EMT), as evidenced by its ability to increase E-cadherin expression and decrease N-cadherin, Snail and MMP-2 expressions in RCC cells. Finally, salinomycin inhibited the tumorigenecity of RCC cells in vivo. Our study provides the evidence that salinomycin possess multiple anti-tumor activities against RCC, as it, in particular, suppressed the cancer stem cell properties and attenuated TGF-beta-induced EMT. Therefore, it may serve as a potentially therapeutic candidate for metastatic RCC and improve the prognosis of RCC patients. PMID- 30273567 TI - Perioperative Echocardiographic Index of Left Ventricular Filling Pressure in Cardiac Surgery. AB - BACKGROUND: The elevated preoperative ratio of early transmitral flow velocity to early diastolic velocity of the mitral annulus (E/e') as an echocardiographic index of left ventricular filling pressure is known to be associated with poor postoperative outcomes. We investigated the association between preoperative and postoperative E/e' elevation and clinical outcomes after cardiac operations. METHODS: The study divided 1,353 patients who underwent cardiac operations into four groups: preoperative and postoperative E/e' <=15 (low-low), preoperative E/e' <=15 but postoperative E/e' >15 (low-high), preoperative E/e' >15 but postoperative E/e' <=15 (high-low), and preoperative and postoperative E/e' >15 (high-high). Cox proportional hazard analysis was performed. Kaplan-Meier curve analysis was performed before and after propensity score matching. RESULTS: The four perioperative E/e' categories were independently associated with 5-year mortality (hazard ratio, high-high vs low-low: 3.58; low-high vs low-low: 3.75; high-low vs low-low: 1.18). Kaplan-Meier curves showed that mortality was significantly different between the groups (log-rank test: high-high vs. low-low, p < 0.001; low-high vs low-low, p < 0.001). Postoperative intensive care unit and hospital lengths of stay, incidence of acute kidney injury, and 1-year mortality were significantly different. However, after propensity score matching, mortality and the incidence of postoperative acute kidney injury were significantly different only between postoperative E/e' <=15 and E/e' >15, but not between preoperative E/e' <=15 and E/e' >15. CONCLUSIONS: Postoperative E/e' >15 was more strongly associated with mortality and acute kidney injury than preoperative E/e' >15. Measurement of the postoperative E/e' ratio may help in assessing the risk of these patients. PMID- 30273568 TI - Off-Pump Versus On-Pump Impact: Diabetic Patient 5-Year Coronary Artery Bypass Clinical Outcomes. AB - BACKGROUND: For diabetic patients who require coronary artery bypass graft (CABG) operation, controversy persists whether an off-pump or an on-pump approach may be advantageous. This US-based, multicenter, randomized, controlled trial, Department of Veterans Affairs Randomization On versus Off Bypass Follow-up Study, compared diabetic patients' 5-year clinical outcomes for off-pump versus on-pump procedures. METHODS: From 2002 to 2008, 835 medically treated (ie, oral hypoglycemic agent or insulin) diabetic patients underwent either off-pump (n = 402) or on-pump (n = 433) CABG. Five-year primary end points included all-cause death and major adverse cardiovascular events (MACE; composite included all-cause death, myocardial infarction, or repeat revascularization). Secondary 5-year end points included cardiac death and MACE-related components. With baseline risk factors balanced, outcomes were evaluated by using a p value less than or equal to 0.01; nonsignificant trends were reported for p values greater than 0.01 and less than or equal to 0.15. RESULTS: Five-year all-cause death rates were 20.2% off pump versus 14.1% on pump (p = 0.0198). No differences were seen in MACE (32.6% off-pump approach versus 28.6% on-pump approach, p = 0.216), repeat revascularization (12.4% off-pump approach versus 11.8% on-pump approach, p = 0.770), and nonfatal myocardial infarction (12.7% off-pump approach versus 10.4% on-pump approach, p = 0.299). Cardiac death trended worse with off-pump CABG (9.0%) than with on-pump CABG (6.25%, p = 0.137). Sensitivity analyses that removed conversions confirmed these findings. CONCLUSIONS: With a 6.1% absolute difference, a strong trend toward improved 5-year survival was observed with on pump CABG for medically treated diabetic patients. No off-pump advantage was found for any 5-year end points. A future clinical trial now appears warranted to rigorously compare off-pump versus on-pump longer term outcomes for diabetic patients. PMID- 30273569 TI - Costs Five Years After Off-Pump or On-Pump Coronary Artery Bypass Surgery. AB - BACKGROUND: Coronary artery bypass grafting (CABG) is a common surgical treatment for ischemic heart disease. Little is known about the long-term costs of conducting the surgery on-pump or off-pump. METHODS: As part of the Randomized On/Off Bypass follow-up study, we followed 2,203 participants randomized to on pump (n = 1,099) and off-pump (n = 1,104) CABG for 5 years using Department of Veterans Affairs and Medicare administrative data. We examined annual costs through 5 years, standardized to 2016 dollars, using multivariate regression models, controlling for site and baseline patient factors. RESULTS: In the first year, including the CABG surgery, annual average costs were $66,599 (SE, $1,946) for the on-pump group and $70,552 (SE, $1,954) for the off-pump group. In years 2 to 5, average costs ranged from $15,000 to $20,000 per year. There was no significant difference between on-pump and off-pump across the 5 years. We explored differences among high-risk subgroups (diabetes, chronic obstructive pulmonary disease, peripheral vascular disease, cerebrovascular disease, renal dysfunction, ejection fraction < 35%, over age 70 years), and found no treatment assignment by time interactions, except for a nonsignificant trend in patients with diabetes. CONCLUSIONS: At 5 years, the average costs of off-pump and on-pump CABG patients did not statistically differ. Costs do not favor one approach and the decision should be based on clinical risks, especially in subgroups. Future research is warranted to examine post-CABG costs and outcomes for diabetic patients over time. PMID- 30273570 TI - Intra-Extra Cardiac Versus Extracardiac Fontan Modifications: Comparison of Early Outcomes. AB - BACKGROUND: Intra-extracardiac (IE) Fontan modification has advantages over the lateral tunnel modification. A direct comparison of Intra-extracardiac (IE) to the Extracardiac (EC) modification so far has not been done. This study aims to compare IE to EC Fontan, with respect to early postoperative outcomes. METHODS: We retrospectively compared outcomes of the Fontan operation using either the Intra-extracardiac (IE) or Extracardiac (EC) conduit modification between January 2012 and December 2016. IE and EC groups were compared using univariate and multivariable regression analysis. To eliminate the confounding effects of fenestration, repeat intergroup comparison was performed after excluding non fenestrated patients. RESULTS: 81 patients were grouped according to Fontan modification into IE group (n=43) and EC group ( n=38). The Fontan was fenestrated in 100% of IE group compared to only 55% of EC group (p<0.001). Cardiopulmonary bypass time was shorter for the IE group (74 vs. 103, p<0.001) The IE patients had median cross clamp time of 34 minutes, while the EC group required cross clamping only in 2 cases (35, 95 minutes) (p<0.001). IE group had significantly shorter median duration of pleural effusion (8 days vs. 11 days, p=0.007) and hospital length of stay (9 days vs. 13 days, p=0.001) than the EC group. Multivariable linear regression analysis revealed that IE modification independently associated with reduced duration of pleural effusion (p=0.004) and hospital LOS (p=0.003). Presence of any unfavorable hemodynamics on preoperative assessment was also associated with longer duration of pleural effusion and hospital LOS for patients with fenestration. CONCLUSIONS: IE Fontan modification may be associated with reduced duration of postoperative pleural effusion and hospital length of stay compared to EC modification. PMID- 30273572 TI - Intensity of Glycemic Control Affects Long-Term Survival After Coronary Artery Bypass Graft Surgery. AB - BACKGROUND: A patient's HbA1c, regardless of diabetic status, is a measure of glycemic control. Studies have found it to be an independent predictor of short term mortality in patients undergoing CABG. In this study, we used pre-operative HbA1c to assess if levels are associated with short- and long-term survival after CABG. METHODS: From a regional registry of consecutive cases we identified a cohort of 6,415 patients undergoing on-pump, isolated CABG from 2008-2015 with documented pre-operative HbA1c level. We defined four HbA1c groups: <5.7 (N=1,713); 5.7-6.4 (N=2,505); 6.5-8.0 (N=1,377); >8 (N=820). Relationship to in hospital outcomes and long-term survival was assessed. Outcome rates and hazard ratios (HR) were adjusted for patient and disease risk factors using multivariable logistic regression and Cox models. RESULTS: The study included 3,740 patients (58%) not diagnosed as diabetic and 2,674 diabetics. Fifty-two percent (1933) of non-diabetics were pre-diabetics (5.7-6.4). Higher HbA1c values were associated with younger age, female gender, greater BMI, more comorbid diseases, lower EF, more 3-vessel coronary disease and recent MI (p trend for all <0.05). After adjustment for patient risk, greater HbA1c values were not associated with higher rates of in-hospital mortality or morbidity. Long-term survival was significantly worse as HbA1c increased. Risk of death increased by 13% for every unit increase in HbA1c (adjHR=1.13, CI05% 1.07-1.19, P<.001). CONCLUSIONS: Pre-admission glycemic control, as assessed by HbA1c, is predictive of long-term survival with higher levels associated with poorer prognosis. It remains to be determined if this risk can be modified by better glycemic control post-operatively. PMID- 30273571 TI - The Prognostic Significance of c-MYC Amplification in Esophageal Squamous Cell Carcinoma. AB - BACKGROUND: We investigated the frequency of c-MYC amplification in esophageal squamous cell carcinoma (ESCC), including both stage I-II and III-IVa disease, and evaluated the correlation of c-MYC amplification with clinicopathologic parameters and outcome. METHODS: In 259 ESCC resected at Zhongshan Hospital, Fudan University from January 2007 to November 2010, c-MYC amplification was analyzed using tissue microarray, with fluorescence in situ hybridization (FISH) assay. RESULTS: c-MYC gene amplification was found in 43.2% (112/259) of ESCC patients. There were significant differences between c-MYC amplification and patient age (P=0.009), and lymph node metastasis (P=0.046). The median follow-up period was 33 months (range 4-102 months). There was a survival difference between patients with different c-MYC status. Among 112 patients with c-MYC amplification, a significantly poorer prognosis was observed, with a median DFS and OS of 24.0 and 31.0 months compared to 48.0 and 48.0 months for those without c-MYC amplification (P=0.011 and 0.018). Upon univariate and multivariate analysis, site, clinical stage, lymph node metastasis, adjuvant therapy and c-MYC amplification were associated with DFS and OS. When patients were divided into stage I-II and stage III-IV subgroups, c-MYC amplification tended to associate with poorer survival, but without statistical difference (P>0.05). CONCLUSIONS: c MYC amplification was associated with age and lymph node metastasis, and was an independent poor-prognostic factor for DFS and OS in full cohort of ESCC patients.

PMID- 30273574 TI - Defining Proficiency for The Society of Thoracic Surgeons Participants Performing Thoracoscopic Lobectomy. AB - BACKGROUND: Parameters defining attainment and maintenance of proficiency in thoracoscopic video-assisted thoracic surgery (VATS) lobectomy remain unknown. To address this knowledge gap, this study investigated the institutional performance curve for VATS lobectomy by using risk-adjusted cumulative sum (Cusum) analysis. METHODS: Using The Society of Thoracic Surgeons General Thoracic Surgery Database, the study investigators identified centers that had performed a total of 30 or more VATS lobectomies. Major morbidity, mortality, and blood transfusion were deemed primary outcomes, with expected incidence derived from risk-adjusted regression models. Acceptable and unacceptable failure rates for outcomes were set a priori according to clinical relevance and informed by regression model output. RESULTS: Between 2001 and 2016, 24,196 patients underwent VATS lobectomy at 159 centers with a median volume of 103 (range, 30 to 760). Overall rates of operative mortality, major morbidity, and transfusion were 1% (244 of 24,189), 17.1% (4,145 of 24,196), and 4% (975 of 24,196), respectively. Of the highest volume centers (>=100 cases), 84% (65 of 77) and 82 % (63 of 77) (p = 0.48) were proficient by major morbidity standards by their 50th and 100th cases, respectively. Similarly, 92% (71 of 77) and 90% (69 of 77) (p = 0.41) of centers showed proficiency by transfusion standards by their 50th and 100th cases, respectively. Three performance patterns were observed: (1) initial and sustained proficiency, (2) crossing unacceptability thresholds with subsequent improved performance; and (3) crossing unacceptability thresholds without subsequent improved performance. CONCLUSIONS: VATS lobectomy outcomes have improved with lower mortality and transfusion rates. The majority of high-volume centers demonstrated proficiency after 50 cases; however, maintenance of proficiency is not ensured. Cusum provides a simple yet powerful tool that can trigger internal audits and performance improvement initiatives. PMID- 30273575 TI - Assessing the spread of foot and mouth disease in mainland China by dynamical switching model. AB - In mainland China, there are three prevalent serotypes of foot and mouth disease virus (FMDV) and they circulate in different susceptible animals, which respond to viral infection in various ways and present different prevalent features. Although powerful control measures are carried on regularly, the epidemic are still prevalent in livestock. Therefore it is essential to assess the disease trends of foot and mouth disease (FMD) in domestic animals in mainland China. The participation of contaminated environment in the transmission dynamics has been confirmed in laboratory research and it can alter the conditions for FMDV invasion and persistence. So environment transmission plays a key role in disease spreading process. In this paper, we establish a dynamical switching model with environment transmission to investigate the relevant internal force mechanism with respect to the threshold switching, effect of saturation of the quantity of FMDV in environment, and prevalent characteristics of the disease in mainland China. Through the dynamical analysis of the model, we understand that under different conditions, there may appear coexistence of one, two, three or even four steady states, and bistability might occur, showing that the development trend of epidemic not only depends on the model parameters, but also is associated with the initial condition. We further study the influence of key parameters on the dynamical behavior and classify the parameter space into several regions with different composition patterns. Applying the model to assess the development trend of FMD in livestock in mainland China, we find that under certain conditions, some of the serotypes persists and some may disappear, thus we can provide some suggestions for disease control of prevailing serotype. PMID- 30273576 TI - A thermodynamic framework for modelling membrane transporters. AB - Membrane transporters contribute to the regulation of the internal environment of cells by translocating substrates across cell membranes. Like all physical systems, the behaviour of membrane transporters is constrained by the laws of thermodynamics. However, many mathematical models of transporters, especially those incorporated into whole-cell models, are not thermodynamically consistent, leading to unrealistic behaviour. In this paper we use a physics-based modelling framework, in which the transfer of energy is explicitly accounted for, to develop thermodynamically consistent models of transporters. We then apply this methodology to model two specific transporters: the cardiac sarcoplasmic/endoplasmic Ca2+ ATPase (SERCA) and the cardiac Na+/K+ ATPase. PMID- 30273577 TI - Interaction of palmitate and LPS regulates cytokine expression and apoptosis through sphingolipids in human retinal microvascular endothelial cells. AB - Studies have implicated saturated fatty acid (SFA) and lipopolysaccharide (LPS) in diabetic retinopathy. Since type 2 diabetes is associated with increases in both SFA and LPS in circulation, we investigated how SFA interacts with LPS to regulate proinflammatory cytokine expression and apoptosis in human retinal microvascular endothelial cells (HRMVECs) and the underlying mechanisms. HRMVECs were challenged with palmitate, a major SFA, LPS or palmitate plus LPS and the expression of proinflammatory cytokines were quantified using real-time PCR and enzyme-linked immunosorbent assay. The interaction between palmitate and LPS on inflammatory signaling and sphingolipid metabolism was demonstrated by immunoblotting and lipidomic analysis, respectively. The effect of palmitate and LPS on apoptosis was also studied by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) and histone-associated DNA fragment assays. Results showed that palmitate robustly stimulated the expression of proinflammatory cytokines including interleukin (IL)-6 and IL-1beta, and the combination of palmitate and LPS further upregulated the proinflammatory cytokines by cooperatively stimulating inflammatory signaling pathways. Results also showed that while palmitate stimulated ceramide (CER) production via CER de novo synthesis and sphingomyelin (SM) hydrolysis, addition of LPS further increased CER de novo synthesis, but not SM hydrolysis. The involvement of sphingolipids in the cooperative stimulation by palmitate and LPS on cytokine expression was indicated by the findings that the inhibitor of CER de novo synthesis or SM hydrolysis attenuated the stimulation of IL-6 expression by palmitate and LPS. In addition, our study showed that fatty acid receptors GPR40 and CD36 were involved in the IL-6 upregulation by palmitate and LPS. Furthermore, palmitate induced apoptosis via CER production, but addition of LPS did not further increase apoptosis. Taken together, this study showed that palmitate interacted with LPS to upregulate cytokine expression via free fatty acid receptor-mediated inflammatory signaling and sphingolipid metabolism in HRMVECs. In contrast, the interaction between palmitate and LPS did not further increase apoptosis. PMID- 30273578 TI - Knockdown of the thyroid hormone transporter MCT8 in chicken retinal precursor cells hampers early retinal development and results in a shift towards more UV/blue cones at the expense of green/red cones. AB - Thyroid hormones (THs) play a crucial role in coordinating brain development in vertebrates. They fine-tune processes like cell proliferation, migration, and differentiation mainly by regulating the transcriptional activity of many essential genes. Regulators of TH availability thereby define the cellular concentration of the bioactive 3,5,3'-triiodothyronine, which binds to nuclear TH receptors. One important regulator, the monocarboxylate transporter 8 (MCT8), facilitates cellular TH uptake and is known to be necessary for correct brain development, but data on its potential role during retinal development is lacking. The retinal cyto-architecture has been conserved throughout vertebrate evolution, and we used the chicken embryo to study the need for MCT8 during retinal development. Its external development allows easy manipulation, and MCT8 is abundantly expressed in the retina from early stages onwards. We induced MCT8 knockdown by electroporating a pRFP-MCT8-RNAi vector into the retinal precursor cells (RPCs) at embryonic day 4 (E4), and studied the consequences for early (E6) and late (E18) retinal development. The empty pRFP-RNAi vector was used as a control. RPC proliferation was reduced at E6. This resulted in cellular hypoplasia and a thinner retina at E18 where mainly photoreceptors and horizontal cells were lost, the two predominant cell types that are born around the stage of electroporation. At E6, differentiation into retinal ganglion cells and amacrine cells was delayed. However, since the proportion of a given cell type within the transfected cell population at E18 was similar in knockdown and controls, the partial loss of some cell types was most-likely due to reduced RPC proliferation and not impaired cell differentiation. Photoreceptors displayed delayed migration at first, but had successfully reached the outer nuclear layer at E18. However, they increasingly differentiated into short wavelength-sensitive cones at the expense of medium/long wavelength-sensitive cones, while the proportion of rods was unaltered. Improperly formed sublaminae in the inner plexiform layer additionally suggested defects in synaptogenesis. Altogether, our data echoes effects of hypothyroidism and the loss of some other regulators of TH availability in the developing zebrafish and rodent retina. Therefore, the expression of MCT8 in RPCs is crucial for adequate TH uptake during cell type specific events in retinal development. PMID- 30273579 TI - Clustering of spin-labeled cholesterol analog diluted in bilayers of saturated and unsaturated phospholipids. AB - Clustering of spin-labeled cholesterol analog, 3beta-doxyl-5alpha-cholestane (DChl), diluted in bilayers comprised of either saturated dipalmitoyl-glycero phosphocholine (DPPC) or unsaturated dioleoyl-glycero-phosphocholine (DOPC) phospholipids was studied. DChl molar fraction X varied between 0.005 and 0.04. EPR spectroscopy applied at low temperatures (200 K) enabled exploring magnetic dipole-dipole (d-d) interaction between spin labels. For DOPC bilayers, EPR spectra were found to broaden remarkably with X increase. The broadening was simulated for the models of 2-dimentional (2-D) clusters with enhanced local concentration, Xloc, which was several times larger than X, and for 1-dimensional (1-D) DChl clusters. The distance of closest approach in these simulations attained the intermolecular lateral distance in the membrane (~0.7 nm). For DPPC bilayers, EPR spectra showed only small broadening, which in these simulations could not be reproduced even if Xloc was taken as small as X. However strong concentration dependence was found for electron spin echo (ESE) decays. Both the EPR and ESE data for DPPC bilayers were explained within the model assuming encapsulation of DChl molecules in lipid shells so preventing them to approach each other closer than a certain distance, Rmin. The Rmin value was found to vary between ~2.5 nm and 5 nm, for X varying between 0.04 and 0.005; Xloc in these simulations was several times larger than X. So the DChl clustering in DOPC bilayers is driven by attractive lipid-mediated forces, while in DPPC bilayers long-range nanoscale lipid-mediated repulsive/attractive forces take place for distances smaller and larger Rmin, correspondingly. PMID- 30273580 TI - Single-cell unroofing: probing topology and nanomechanics of native membranes. AB - Cell membranes separate the cell interior from the external environment. They are constituted by a variety of lipids; their composition determines the dynamics of membrane proteins and affects the ability of the cells to adapt. Even though the study of model membranes allows to understand the interactions among lipids and the overall mechanics, little is known about these properties in native membranes. To combine topology and nanomechanics analysis of native membranes, I designed a method to investigate the plasma membranes isolated from a variety of single cells. Five cell types were chosen and tested, revealing 20% variation in membrane thickness. I probed the resistance of the isolated membranes to indent, finding their line tension and spreading pressure. These results show that membranes isolated from neurons are stiffer and less diffusive than brain cancer cell membranes. This method gives direct quantitative insights on the mechanics of native cell membranes. PMID- 30273581 TI - Casein interaction with lipid membranes: Are the phase state or charge density of the phospholipids affecting protein adsorption? AB - Casein micelles are ~200 nm electronegative particles that constitute 80 wt% of the milk proteins. During synthesis in the lactating mammary cells, caseins are thought to interact in the form of ~20 nm assemblies, directly with the biological membranes of the endoplasmic reticulum and/or the Golgi apparatus. However, conditions that drive this interaction are not yet known. Atomic force microscopy imaging and force spectroscopy were used to directly observe the adsorption of casein particles on supported phospholipid bilayers with controlled compositions to vary their phase state and surface charge density, as verified by X-ray diffraction and zetametry. At pH 6.7, the casein particles adsorbed onto bilayer phases with zwitterionic and liquid-disordered phospholipid molecules, but not on phases with anionic or ordered phospholipids. Furthermore, the presence of adsorbed caseins altered the stability of the yet exposed bilayer. Considering their respective compositions and symmetry/asymmetry, these results cast light on the possible interactions of casein assemblies with the organelles' membranes of the lactating mammary cells. PMID- 30273582 TI - Maternal biomarkers for fetal heart failure in fetuses with congenital heart defects or arrhythmias. AB - BACKGROUND: Diagnosis of fetal heart failure depends primarily on fetal ultrasonography assessment. Our recent study demonstrated that plasma natriuretic peptide levels in umbilical cord blood were correlated with the severity of heart failure in fetuses with congenital heart defects or arrhythmias. However, percutaneous umbilical blood sampling is an invasive procedure, and therefore, less or noninvasive biomarkers reflecting fetal heart failure are required. OBJECTIVE: The aim of this study was to investigate the possibility of whether maternal serum biomarkers can diagnose fetal heart failure in fetuses with congenital heart defects or arrhythmias. STUDY DESIGN: This exploratory cross sectional study was conducted at a tertiary pediatric cardiac center. A total of 50 singletons with fetal congenital heart defects or arrhythmias and 50 controls who were registered in the National Cerebral and Cardiovascular Center Biobank from 2013 to 2016 were included. Maternal serum samples obtained during the third trimester were analyzed for 2 hormones and 36 cytokines using the Bio-Plex Pro Human Cancer Biomarker panels 1 and 2. We comprehensively analyzed the association between maternal serum biomarkers and ultrasonography findings or fetal arrhythmia status. Fetal heart failure was defined as a cardiovascular profile score <=7. RESULTS: Of 37 fetuses with congenital heart defects, heart failure was found in 1 case of tricuspid valve dysplasia with moderate tricuspid regurgitation. Of 13 fetuses with arrhythmias, 5 had heart failure at 28-33 weeks of gestation. Maternal serum cytokine and hormone concentrations were compared between patients with and without fetal heart failure at 28-33 weeks of gestation (n = 6 and n = 61, respectively). Sixty-one fetuses without heart failure consisted of 10 with congenital heart defect, 6 with arrhythmia, and 45 controls. Maternal serum concentrations of tumor necrosis factor-alpha, interleukin-6, soluble Fas ligand, transforming growth factor-alpha, and vascular endothelial growth factor-D were significantly higher when fetuses had heart failure than when they did not (P < .05), whereas maternal serum concentrations of heparin binding epidermal growth factor-like growth factor were significantly lower when fetuses had heart failure than when they did not (P < .05). Multivariate analysis showed that maternal serum concentrations of tumor necrosis factor-alpha, vascular endothelial growth factor-D, and heparin-binding epidermal growth factor like growth factor were independently associated with fetal heart failure. The cutoff values were as follows: tumor necrosis factor-alpha, 68 pg/mL (sensitivity of 50.0%, specificity of 93.4%, positive likelihood ratio of 7.6, negative likelihood ratio of 0.5); vascular endothelial growth factor-D, 1156 pg/mL (sensitivity of 50.0%, specificity of 93.4%, positive likelihood ratio of 7.6, negative likelihood ratio of 0.5); and heparin-binding epidermal growth factor like growth factor, 90 pg/mL (sensitivity of 83.3%, specificity of 83.6%, positive likelihood ratio of 5.1, negative likelihood ratio of 0.2). The combination of these 3 cytokines showed sensitivity of 100%, specificity of 80.3%, positive likelihood ratio of 5.1, and negative likelihood ratio of 0. In the absence of fetal heart failure, concentrations of all maternal serum cytokines and hormones were similar in cases of fetal congenital heart defects and controls, while maternal serum soluble CD40 ligand concentrations were increased only in fetal arrhythmias. CONCLUSION: Maternal serum concentrations of tumor necrosis factor-alpha, vascular endothelial growth factor-D, and heparin binding epidermal growth factor-like growth factor were associated with fetal heart failure. PMID- 30273583 TI - Interpersonal trauma and aging-related genitourinary dysfunction in a national sample of older women. AB - BACKGROUND: Among reproductive-aged women, exposure to interpersonal trauma is associated with genitourinary symptoms. Little is known about the relationship between these exposures and the genitourinary health of older women, who tend to experience different and more prevalent genitourinary symptoms because of menopause and aging. OBJECTIVES: In this study, we examined relationships between common types of interpersonal trauma and aging-related genitourinary dysfunction among older women. STUDY DESIGN: We analyzed data from the National Social Life, Health, and Aging Project, a national area probability sample of older community dwelling adults born between 1920 and 1947. We used cross-sectional data from home-based study visits conducted in 2005-2006 to examine interpersonal violence exposures (any lifetime sexual assault, past-year emotional and physical abuse), and past-year genitourinary symptoms (urinary incontinence, other urinary problems, and vaginal pain/lubrication problems with sexual intercourse) among women participants. Multivariable logistic regression models were used to relate interpersonal violence and genitourinary symptoms, adjusting for age, race/ethnicity, body mass index, education, marital status, parity, hormone therapy, depressive and anxiety symptoms, and self-reported health. In exploratory models, we further adjusted for vaginal maturation, a tissue-specific marker of aging-related urogenital atrophy obtained from vaginal self-swabs. RESULTS: In this national sample of 1551 older women (mean age 69 +/- 2 years), 9% reported sexual assault, 23% reported emotional abuse, and <1% reported physical abuse. Urinary incontinence and other urinary problems were reported by 42% and 17%, respectively, and 42% of sexually active women (n = 527) reported vaginal symptoms with intercourse. In multivariable regression analyses adjusted for age, race/ethnicity, education, marital status, parity, hormone therapy, anxiety, depressive symptoms, and self-reported health, women with any lifetime history of sexual assault had 2.5 times the odds (95% confidence interval, 1.0 6.3) of vaginal symptoms, while women who reported past-year emotional abuse had higher odds of urinary incontinence (odds ratio, 1.7, 95% confidence interval, 1.2-2.4) and other urinary problems (odds ratio, 1.8, 95% confidence interval, 1.2-2.8). Among women who provided vaginal self-swabs (n = 869), adjustment for vaginal maturation-attenuated associations with other urinary problems (odds ratio, 1.6, 95% confidence interval, .9-2.6) and vaginal symptoms (odds ratio, 2.2, 95% confidence interval, 0.8-5.8). CONCLUSION: Sexual assault and emotional abuse may play a role in the development or experience of aging-related genitourinary dysfunction in older women. Clinicians caring for older women should recognize the prevalence and importance of traumatic exposures in health related to menopause and aging. PMID- 30273584 TI - Tackling poorly selected, collected, and reported outcomes in obstetrics and gynecology research. AB - Clinical research should ultimately improve patient care. To enable this, randomized controlled trials must select, collect, and report outcomes that are both relevant to clinical practice and genuinely reflect the perspectives of key stakeholders including health care professionals, researchers, and patients. Unfortunately, many randomized controlled trials fall short of this requirement. Complex issues, including a failure to take into account the perspectives of key stakeholders when selecting outcomes, variations in outcome definitions and measurement instruments, and outcome reporting bias make research evidence difficult to interpret, undermining the translation of research into clinical practice. Problems with poor outcome selection, measurement, and reporting can be addressed by developing, disseminating, and implementing core outcome sets. A core outcome set represents a minimum data set of outcomes developed using robust consensus science methods engaging diverse stakeholders including health care professionals, researchers, and patients. Core outcomes should be routinely utilized by researchers, collected in a standardized manner, and reported consistently in the final publication. They are currently being developed across our specialty including infertility, endometriosis, and preeclampsia. Recognizing poorly selected, collected, and reported outcomes as serious hindrances to progress in our specialty, more than 80 journals including the Journal, have come together to support the Core Outcomes in Women's and Newborn Health (CROWN) initiative. The consortium supports researchers to develop, disseminate, and implement core outcome sets. Implementing core outcome sets could make a profound contribution to addressing poorly selected, collected, and reported outcomes. Implementation should ensure future randomized controlled trials hold the necessary reach and relevance to inform clinical practice, enhance patient care, and improve patient outcomes. PMID- 30273585 TI - Early preterm preeclampsia outcomes by intended mode of delivery. AB - BACKGROUND: The optimal route of delivery in early-onset preeclampsia before 34 weeks is debated because many clinicians are reluctant to proceed with induction for perceived high risk of failure. OBJECTIVE: Our objective was to investigate labor induction success rates and compare maternal and neonatal outcomes by intended mode of delivery in women with early preterm preeclampsia. STUDY DESIGN: We identified 914 singleton pregnancies with preeclampsia in the Consortium on Safe Labor study for analysis who delivered between 24 0/7 and 33 6/7 weeks. We excluded fetal anomalies, antepartum stillbirth, or spontaneous preterm labor. Maternal and neonatal outcomes were compared between women undergoing induction of labor (n = 460) and planned cesarean delivery (n = 454) and women with successful induction of labor (n = 214) and unsuccessful induction of labor (n = 246). We calculated relative risks and 95% confidence intervals to determine outcomes by Poisson regression model with propensity score adjustment. The calculation of propensity scores considered covariates such as maternal age, gestational age, parity, body mass index, tobacco use, diabetes mellitus, chronic hypertension, hospital type and site, birthweight, history of cesarean delivery, malpresentation/breech, simplified Bishop score, insurance, marital status, and steroid use. RESULTS: Among the 460 women with induction (50%), 47% of deliveries were vaginal. By gestational age, 24 to 27 6/7, 28 to 31 6/7, and 32 to 33 6/7, the induction of labor success rates were 38% (12 of 32), 39% (70 of 180), and 54% (132 of 248), respectively. Induction of labor compared with planned cesarean delivery was less likely to be associated with placental abruption (adjusted relative risk, 0.33; 95% confidence interval, 0.16-0.67), wound infection or separation (adjusted relative risk, 0.23; 95% confidence interval, 0.06-0.85), and neonatal asphyxia (0.12; 95% confidence interval, 0.02-0.78). Women with vaginal delivery compared with those with failed induction of labor had decreased maternal morbidity (adjusted relative risk, 0.27; 95% confidence interval, 0.09 0.82) and no difference in neonatal outcomes. CONCLUSION: About half of women with preterm preeclampsia who attempted an induction had a successful vaginal delivery. The rate of successful vaginal delivery increases with gestational age. Successful induction has the benefit of preventing maternal and fetal comorbidities associated with previous cesarean deliveries in subsequent pregnancies. While overall rates of a composite of serious maternal and neonatal morbidity/mortality did not differ between induction of labor and planned cesarean delivery groups, women with failed induction of labor had increased maternal morbidity highlighting the complex route of delivery counseling required in this high-risk population of women. PMID- 30273586 TI - Liposomal bupivacaine efficacy for postoperative pain following posterior vaginal surgery: a randomized, double-blind, placebo-controlled trial. AB - BACKGROUND: Effective postoperative pain management is a crucial component of recovery following surgery. Narcotics are a cornerstone of postoperative analgesia, but can require a redosing requirement, encompass a lengthy list of side effects and adverse reaction risks, as well as carry a dependency potential. The national focus on decreasing opioid use has directly impacted postoperative pain management. Previous studies have reported the beneficial use of a single intraoperative injection of extended-release liposomal bupivacaine in postoperative pain management, however the same results have not been extensively studied in the urogynecology literature. OBJECTIVE: We sought to evaluate cumulative postoperative vaginal pain on days 1 and 3 after posterior vaginal wall surgery comparing study medication (extended-release liposomal bupivacaine) to placebo (saline). Secondary aims were to evaluate vaginal pain on postoperative day 7 and total morphine-equivalent narcotic usage on days 1, 3, and 7. STUDY DESIGN: This is a randomized, double-blinded, placebo-controlled trial with 100 subjects recruited from Walter Reed National Military Medical Center urogynecology clinic. All subjects were age >18 years and scheduled for surgery involving the posterior vaginal wall or muscularis (including posterior colporrhaphy, colpocleisis, sphincteroplasty, perineorrhaphy), excluding those with regular narcotic usage or concurrent pain management requiring the use of epidural anesthesia. A sample size of 96 patients was calculated. Subjects were randomized to receive either 20 mL of extended-release liposomal bupivacaine (Exparel) (Pacira Pharmaceuticals Inc, Parsippany, NJ) or 20 mL of placebo (saline) at the end of surgery. Concealed syringes were used and injected immediately postoperative into the lateral vaginal wall/levator muscle area and perineal body. In-house morphine-equivalent narcotic usage was recorded along with the postoperative day 1 pain scores. Patients were contacted by telephone on postoperative days 3 and 7. Vaginal pain scores were evaluated using the Defense and Veterans Pain Rating Scale, cumulatively and on days 1, 3, and 7. Overall morphine-equivalent narcotics were compared between the 2 groups. RESULTS: From October 2014 through August 2017, 100 patients were enrolled and completed the study; 49 (49%) of the patients were randomized to the study group and 51 (51%) were in the placebo group. There was no significant difference between vaginal pain scores between the study group and the placebo group (postoperative day 1: study medication median score 1 [interquartile range 0-3], placebo median score 1 [interquartile range 0-3] [P = .59]; postoperative day 3: study medication median score 2 [interquartile range 0-3], placebo median score 1 [interquartile range 0 3] [P = .20]; postoperative day 7: study medication median score 3 [interquartile range 1-4], placebo median score 1.5 [interquartile range 0-3] [P = .06]). Cumulative pain scores postoperative day 1-7 were also not significant (study medication median score 6 [interquartile range 1-10], placebo median score 4 [interquartile range 1-8] [P = .14]). Multivariate model for the presence of vaginal pain was calculated and after controlling for body mass index, age, and combined laparoscopy surgery, there was no significant difference between the study and the placebo groups (P = .62). There was no statistically significant difference in morphine equivalents for the 2 groups: study medication 112.5 (interquartile range 45-207) and placebo 101.5 (interquartile range 37.5-195), P = .81. CONCLUSION: The use of extended-release liposomal bupivacaine in posterior vaginal wall surgeries, injected into the lateral posterior vaginal wall and perineal body, does not provide a significant decrease in postoperative pain or decrease narcotic medication usage when compared to saline. PMID- 30273587 TI - Trends in pregnancy-associated mortality involving opioids in the United States, 2007-2016. PMID- 30273588 TI - Association of levator injury and urogynecological complaints in women after their first vaginal birth with and without mediolateral episiotomy. AB - BACKGROUND: Pelvic organ prolapse is a common health problem in women and has a negative influence on quality of life. A major cause of pelvic organ prolapse is levator injury. OBJECTIVE: The objective of the study was to evaluate the association of mediolateral episiotomy with levator injury (levator avulsion, ballooning, or combined) and urogynecological complaints. STUDY DESIGN: A prospective observational cohort study was performed in 204 primiparous women with a spontaneous vaginal delivery without anal sphincter tear in a general hospital between 2012 and 2015. One hundred three of these women had had a mediolateral episiotomy. Validated urogynecological questionnaires and transperineal 3-dimensional/4-dimensional ultrasound were completed after delivery. Outcome measures were levator avulsion, ballooning (hiatal area of more than 25 cm2), and urogynecological questionnaire scores. Statistical analysis was performed using univariate and multiple logistic regression analysis. RESULTS: The median time at investigation after vaginal delivery was 13 months (range 6 33). Levator injury (avulsion, ballooning, or combined) was identified in 35 of the 103 women who had undergone mediolateral episiotomy (40.0%) and 33 of the 101 women without episiotomy (32.7%) (P = .69). No differences were found in the incidence of levator avulsion 27 (26.7%) vs 23 (22.8%) (P = .53) or in levator ballooning (20 [19.4%] vs 23 [22.8%] (P = .58) between both groups. There was an association between longer duration of the second stage of labor and the incidence of levator avulsion (odds ratio, 1.24 [95% confidence interval, 1.01 1.52]). Nonocciput anterior fetal position increased the risk of levator ballooning and levator injury (odds ratio, 10.19 [95% confidence interval, 1.89 54.91] and odds ratio, 12.16 [95% confidence interval, 1.41-104.38], respectively). No differences in urogynecological complaints were found. CONCLUSION: Mediolateral episiotomy is not associated with the occurrence of levator injury or urogynecological complaints in women with a spontaneous vaginal delivery who did not obtain an anal sphincter injury. Levator injury was associated with a prolonged second stage of labor and a nonocciput anterior fetal position. PMID- 30273589 TI - Quality of life and fear of cancer recurrence in T1 colorectal cancer patients treated with endoscopic or surgical tumor resection. AB - BACKGROUND AND AIMS: To optimize therapeutic decision-making in T1 colorectal cancer (T1 CRC) patients, it is important to elicit the patient's perspective next to considering medical outcome. Because empirical data on patient-reported impact of different treatment options are lacking, we evaluated patients' quality of life, perceived time to recovery and fear of cancer recurrence after endoscopic or surgical treatment for T1 CRC. METHODS: In this cross-sectional study, we selected patients with histologically confirmed T1 CRC, who participated in the Dutch Bowel Cancer Screening Programme and received endoscopic or surgical treatment between January 2014 and July 2017. Quality of life was measured using the EORTC QLQ-C30 and the EQ-5D-5L questionnaire. We used the Cancer Worry Scale (CWS) to evaluate patients' fear of cancer recurrence. A question on perceived time to recovery after treatment was also included in the set of questionnaires sent to the patients. RESULTS: Of all 119 eligible patients, 92.4% responded to the questionnaire (endoscopy group: 55/62, surgery group: 55/57). Compared with the surgery group, perceived time to recovery was on average 3 months shorter in endoscopically treated patients after adjustment for confounders (19.9 days vs 111.3 days; p = 0.001). The 2 treatment groups were comparable with regard to global quality of life, functioning domains as well as symptom severity scores. Moreover, patients in the endoscopy group did not report more fear of cancer recurrence than those in the surgery group (CWS score range 0 40; endoscopy: 7.6 vs surgery: 9.7; p = 0.140). CONCLUSIONS: From the patient's perspective, endoscopic treatment provides a quicker recovery than surgery, without provoking more fear of cancer recurrence or any deterioration in quality of life. These results contribute to the shared therapeutic decision-making process of clinicians and T1 CRC patients. PMID- 30273590 TI - Blue-light imaging compared with high-definition white light for real-time histology prediction of colorectal polyps less than 1 centimeter: a prospective randomized study. AB - BACKGROUND AND AIMS: Blue-light imaging (BLI) is a new chromoendoscopy technique, potentially useful for differentiating neoplastic from nonneoplastic lesions. The present study was aimed at comparing BLI with high-definition white light (HDWL) in the real-time histology prediction of colon polyps <10 mm. METHODS: Consecutive outpatients undergoing colonoscopy with the ELUXEO 7000 endoscopy platform and 760 series video colonoscopes (Fujifilm Co, Tokyo, Japan) who had at least 1 polyp <10 mm were randomized to BLI or HDWL for polyp characterization. The accuracy of high-confidence real-time histology prediction (adenoma vs not adenoma) by either BLI or HDWL for polyps <10 mm (primary end-point) and diminutive (<=5 mm) polyps was calculated, along with sensitivity, specificity, and positive and negative predictive values, with histopathology as the reference standard. RESULTS: A total of 483 polyps were detected in 245 randomized patients (125 and 120 in the BLI and HDWL arms, respectively). A total of 358 were diminutive, and 283 were adenomas. Overall, 222 (85.7%) and 193 (86.1%) polyps were characterized with high confidence by BLI and HDWL, respectively (P = .887), with an overall accuracy of 92% and 84%, respectively (P = .011). The accuracy was significantly higher by BLI than HDWL, also for diminutive polyps (92% vs 83%; P = .008). When BLI was used, the negative predictive value for diminutive rectosigmoid polyps was 88%, and the post-polypectomy surveillance interval was correctly attributed in 85.7% and 93.7% of patients, respectively, according to U.S. and European guidelines. CONCLUSION: BLI was superior to HDWL for the real time prediction of histology in polyps <10 mm. A BLI-dedicated classification might further improve the endoscopist performance. (Clinical trial registration number: NCT03274115.). PMID- 30273592 TI - Clinical disease activity and endoscopic severity correlate poorly in children newly diagnosed with Crohn's disease. AB - BACKGROUND AND AIMS: Treatment goals in Crohn's disease (CD) have evolved to target mucosal healing. There is now a drive to determine if noninvasive measures can adequately identify the attainment and persistence of this goal. Currently, data describing the relationship between clinical indices and endoscopic appearance in pediatric CD are sparse. Our aim was to compare endoscopic severity with the weighted Pediatric Crohn's Disease Activity Index (wPCDAI) in children with newly diagnosed CD. METHODS: All children aged <=17 years newly diagnosed with CD enrolled in an inception cohort at sites of the Canadian Children Inflammatory Bowel Disease Network were eligible. Clinical disease activity at presentation was evaluated by the wPCDAI and conventional biochemical parameters. Severity of disease at ileocolonoscopy was assessed by the simple endoscopic score for CD (SES-CD), with segmental subscores noted. We evaluated the association of SES-CD and disease activity markers using the Pearson test of correlation, the Spearman rank coefficient, and linear regression models. RESULTS: Two hundred eighty patients from 11 centers were included in the analysis. The median wPCDAI score was 60 (interquartile range, 40-80; 53% severe). Median SES-CD was 16 (interquartile range 10-22; 51% severe). The wPCDAI correlated weakly with SES-CD (r = .39, P < .001). Examination of the individual components that contribute to the wPCDAI demonstrated weak correlation with the SES-CD for all items apart from stooling (moderate correlation, r = .50, P < .001). Routine blood tests did not correlate well with the SES-CD. In regression models, variation in clinical symptoms accounted for most of the variation in both the wPCDAI and SES-CD, with no additional benefit from routine blood tests. CONCLUSIONS: In children with newly diagnosed CD, wPCDAI correlates poorly with endoscopic disease activity. As treatment paradigms evolve to target mucosal healing, clinical markers should not be used in isolation to determine disease activity. PMID- 30273593 TI - Repeated Cannabidiol treatment reduces cocaine intake and modulates neural proliferation and CB1R expression in the mouse hippocampus. AB - Cannabinoid derivatives have shown promising results for treating neuropsychiatric disorders, including drug addiction. Recent studies on the therapeutic effects of Cannabidiol (CBD) on drug abuse showed mixed results, especially with psychostimulant substances such as cocaine. To determine whether CBD can attenuate cocaine reinforcement, we assessed behavioural responses induced by cocaine in mice, using the behavioural sensitization, conditioned place preference and intravenous self-administration paradigms. We show that repeated CBD treatment produces anxiolytic effects in the elevated plus maze test, increases the discrimination index of the novel object recognition task and attenuates cocaine-induced conditioned place preference but does not affect behavioural sensitization. CBD reduced cocaine voluntary consumption and progressive ratio breaking point in the self-administration paradigm, but not drug-induced reinstatement. In parallel, CBD increased expression of type 1 cannabinoid receptor, MAPK-CREB phosphorylation, BDNF expression, and neural cell proliferation in the hippocampus, and reduced the GluA1/2 AMPA subunit receptor ratio in the striatum. In summary, we show that CBD can modulate some behavioural and molecular manifestations of cocaine reinforcement. Moreover, our findings show that CBD has pro-neurogenic effects also in cocaine consuming animals. Overall, this novel evidence provides new perspectives to use CBD as a therapeutic tool. PMID- 30273591 TI - G-EYE colonoscopy is superior to standard colonoscopy for increasing adenoma detection rate: an international randomized controlled trial (with videos). AB - BACKGROUND AND AIMS: Colorectal cancer (CRC) is largely preventable with routine screening and surveillance colonoscopy; however, interval cancers arising from precancerous lesions missed by standard colonoscopy still occur. An increased adenoma detection rate (ADR) has been found to be inversely associated with interval cancers. The G-EYE device includes a reusable balloon integrated at the distal tip of a standard colonoscope, which flattens haustral folds, centralizes the colonoscope's optics, and reduces bowel slippage. The insufflated balloon also aims to enhance visualization of the colon during withdrawal, thereby increasing the ADR. METHODS: In this randomized, controlled, international, multicenter study (11 centers), patients (aged >=50 years) referred to colonoscopy for screening, surveillance, or changes in bowel habits were randomized to undergo either balloon-assisted colonoscopy by using an insufflated balloon during withdrawal or standard high-definition colonoscopy. The primary endpoint was the ADR. RESULTS: One thousand patients were enrolled between May 2014 and September 2016 to undergo colonoscopy by experienced endoscopists; 803 were finally analyzed (standard colonoscopy n = 396; balloon-assisted colonoscopy n = 407). Baseline parameters were similar in both groups. Balloon-assisted colonoscopy provided a 48.0% ADR compared with 37.5% in the standard colonoscopy group (28% increase; P = .0027). Additionally, balloon-assisted colonoscopy provided for a significant increase in detection of advanced (P = .0033) flat adenomas (P < .0001) and sessile serrated adenomas/polyps (P = .0026). CONCLUSION: Balloon-assisted colonoscopy yielded a higher ADR and increased the detection of advanced, flat, and sessile serrated adenomas/polyps when compared with standard colonoscopy. Improved detection by the G-EYE device could impact the quality of CRC screening by reducing miss rates and consequently reducing interval cancer incidence. (Clinical trial registration number: NCT01917513.). PMID- 30273594 TI - Varenicline reduces DNA damage, tau mislocalization and post surgical cognitive impairment in aged mice. AB - Postoperative cognitive dysfunction (POCD) occurs more frequently in elderly patients undergoing major surgery. Age associated cholinergic imbalance may exacerbate postoperative systemic and neuroinflammation, but the effect nicotinic acetylcholine receptor (nAchR) stimulation on the development of POCD remains unclear. Aged male C57BL/6N mice (18 months old) underwent a midline laparotomy or were exposed to sevoflurane anesthesia alone (4-5%), with or without concomitant varenicline, a partial nAchR, at 1 mg/kg/day. Laparotomy increased pro-inflammatory cytokines in the liver and hippocampus (IL-1beta and MCP-1) and induced a decline in cognitive performance, indicated by lower discrimination index in the Novel Object Recognition test, greater error number and longer escape latency in the Y-maze test. Glia activation, aberrant tau phosphorylation (AT8) and accumulation of phosphorylated H2AX in the hippocampus were detectable up to postoperative day 14, with neuronal apoptosis seen in the hippocampus. Perioperative varenicline attenuated the cognitive decline and associated tau protein mislocalization, DNA damage and neuronal apoptosis. The modulation of JAK2/STAT3 signaling may play a critical role in this process. Neuroinflammation, tau phosphorylation and DNA damage contribute to the development of cognitive dysfunction following laparotomy. Cholinergic stimulation by varenicline attenuated these changes through preventing the mislocalization of phosphorylated tau and DNA damage. PMID- 30273596 TI - Notch-signaling activity determines uptake and biological effect of imatinib in systemic sclerosis dermal fibroblasts. AB - Tyrosine kinase inhibitors (TKI) have emerged as therapeutic option for rheumatic diseases such as systemic sclerosis (SSc). Since TKs like c-Abl kinase are important for fibroblast activation and fibrosis development in SSc, the c-Abl inhibitor imatinib was proposed for SSc treatment. Transporters for organic cations have become increasingly recognized as an important determinant for uptake and efficacy of TKI. Therefore, we investigated the role of organic cation transporters in the uptake of imatinib. Moreover, the influence of important SSc pathogenetic factors, like PDGF and Notch- pathway activation on these uptake processes, has been studied. We demonstrated that the organic cation transporters (OCT) 1-3, the OCTN novel (OCTN)1-2, and the multidrug and toxin extrusion protein MATE1 are expressed in healthy dermal and SSc fibroblasts. Interestingly, decreased expression levels of MATE1 and decreased imatinib uptake were measured in SSc fibroblasts. In siRNA experiments, MATE1 was identified as key transporter for imatinib uptake and biological effect in dermal fibroblasts. Furthermore, PDGF reduced imatinib uptake by decreasing MATE1 expression in SSc fibroblasts, but not in healthy fibroblasts. Blocking the Notch pathway in SSc fibroblasts increased MATE1 transporter expression and imatinib uptake. In conclusion, MATE1 mediated transport governs therapeutic efficacy of imatinib in SSc.

AB - We hypothesized that autophagy and associated lysosome function serve as a critical modulator during Nod-like receptor family pyrin domain containing 3 (Nlrp3) inflammasome activation on proatherogenic stimuli. We first demonstrated that 7-ketocholesterol stimulated Nlrp3 inflammasome formation and activation as shown by increased colocalization of inflammasome components [Nlrp3 versus apoptosis associated speck-like protein (Asc) or caspase-1] and enhanced cleavage of caspase-1 into active caspase-1 to generate IL-1beta in coronary artery smooth muscle cells. Deletion of the CD38 gene (CD38-/-) that regulates lysosome function and autophagic flux also led to Nlrp3 inflammasome formation and activation. In the presence of rapamycin, the effects of either 7-ketocholesterol treatment or CD38 gene deletion were abolished. The autophagy inhibitor spautin-1 and the lysosome function blocker bafilomycin A1 also enhanced Nlrp3 inflammasome formation and activation. In animal experiments, we found that increased colocalization of Nlrp3 versus Asc or caspase-1 enhanced IL-1beta accumulation and caspase-1 activity in the coronary arterial wall of CD38-/- mice on the Western diet compared with CD38+/+ mice. This increased colocalization was blocked by treatment with rapamycin but enhanced by chloroquine, a water-soluble blocker of autophagic flux. Morphologic examinations confirmed that the media of coronary arteries was significantly thicker in CD38-/- mice on the Western diet than CD38+/+ mice. In conclusion, the deficiency of autophagic flux promotes Nlrp3 inflammasome formation and activation in coronary artery smooth muscle cells on proatherogenic stimulation, leading to medial thickening of the coronary arterial wall. PMID- 30273597 TI - NEDD4 Is Involved in Inflammation Development during Keloid Formation. AB - Keloids mark a chronic inflammatory disease characterized by a fibroproliferative disorder of the skin. A genome-wide association study showed that single nucleotide polymorphism rs8032158 in the neural precursor cell-expressed NEDD4 gene, which has six protein-coding transcript variants (TVs), is genetically linked to keloids. Here, we show that the high frequency of risk allele C in rs8032158 in keloid patients is associated with a selectively higher expression of TV3 of NEDD4 to activate the NF-kappaB pathway. Comparisons of keloid scars with normal skin samples that do not have the single-nucleotide polymorphism allele and were derived from different anatomical sites showed stronger expressions of NEDD4 TV3 and activated forms of NF-kappaB and STAT3 in keloid scars. Forced expression or selective knockdown of NEDD4 TV3 increased or decreased NF-kappaB activation in vitro. Furthermore, NEDD4 knockdown suppressed NF-kappaB-dependent inflammation development in vivo. Mechanistic analysis showed that NEDD4 TV3 is involved in NF-kappaB activation through its association with the adaptor protein RIP. These results suggest that NEDD4 TV3 is a potential diagnostic marker and therapeutic target for chronic skin diseases, including keloid. PMID- 30273595 TI - Hippocampal neural progenitor cells play a distinct role in fear memory retrieval in male and female CIE rats. AB - Adult male and female GFAP-TK transgenic rats experienced six weeks of chronic intermittent ethanol vapor inhalation (CIE). During the last week of CIE, a subset of male and female TK rats were fed with Valcyte to ablate neural progenitor cells (NPCs). Seventy-two hours after CIE cessation, all CIE and age matched ethanol naive controls experienced auditory trace fear conditioning (TFC). Twenty-four hours later all animals were tested for cue-mediated retrieval in the fear context. Adult male CIE rats showed a significant burst in NPCs paralleled by reduction in fear retrieval compared to naive controls and Valcyte treated CIE rats. Adult female CIE rats did not show a burst in NPCs and showed similar fear retrieval compared to naive controls and Valcyte treated CIE rats, indicating that CIE-mediated impairment in fear memory and its regulation by NPCs was sex dependent. Valcyte significantly reduced Ki-67 and NeuroD labeled cells in the dentate gyrus (DG) in both sexes, demonstrating a role for NPCs in reduced fear retrieval in males. Valcyte prevented adaptations in GluN2A receptor expression and synaptoporin density in the DG in males, indicating that NPCs contributed to alterations in plasticity-related proteins and mossy fiber projections that were associated with reduced fear retrieval. These data suggest that DG NPCs born during withdrawal and early abstinence from CIE are aberrant, and could play a role in weakening long-term memory consolidation dependent on the hippocampus. PMID- 30273599 TI - Enteroviral Infection Leads to Transactive Response DNA-Binding Protein 43 Pathology in Vivo. AB - Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that primarily affects motor neurons in the cerebral cortex, brainstem, and spinal cord, leading to progressive paralysis and eventual death. Approximately 95% of all ALS cases are sporadic without known causes. Enteroviruses have been suspected to play a role in ALS because of their ability to target motor neurons and to cause muscle weakness and paralysis. In vitro enteroviral infection results in cytoplasmic aggregation and cleavage of transactive response DNA binding protein-43, a pathologic hallmark of ALS. However, whether enteroviral infection can induce ALS-like pathologies in vivo remains to be characterized. In this study, neonatal BALB/C mice were intracranially inoculated with either a recombinant coxsackievirus B3 expressing enhanced green fluorescent protein or mock-infected for 2, 5, 10, 30, and 90 days. Histologic and immunohistochemical analysis of brain tissues demonstrated sustained inflammation (microglia and astrogliosis) and lesions in multiple regions of the brain (hippocampus, cerebral cortex, striatum, olfactory bulb, and putamen) in parallel with virus detection as early as 2 days for up to 90 days after infection. Most notably, ALS-like pathologies, including cytoplasmic mislocalization of transactive response DNA binding protein-43, p62-, and ubiquitin-positive inclusions, were observed in the areas of infection. These data provide the first pathologic evidence to support a possible link between enteroviral infection and ALS. PMID- 30273600 TI - Colonoscopic-Guided Pinch Biopsies in Mice as a Useful Model for Evaluating the Roles of Host and Luminal Factors in Colonic Inflammation. AB - Colonic inflammation, a hallmark of inflammatory bowel disease, can be influenced by host intrinsic and extrinsic factors. There continues to be a need for models of colonic inflammation that can both provide insights into disease pathogenesis and be used to investigate potential therapies. Herein, we tested the utility of colonoscopic-guided pinch biopsies in mice for studying colonic inflammation and its treatment. Gene expression profiling of colonic wound beds after injury showed marked changes, including increased expression of genes important for the inflammatory response. Interestingly, many of these gene expression changes mimicked those alterations found in inflammatory bowel disease patients. Biopsy induced inflammation was associated with increases in neutrophils, macrophages, and natural killer cells. Injury also led to elevated levels of sphingosine-1 phosphate (S1P), a bioactive lipid that is an important mediator of inflammation mainly through its receptor, S1P1. Genetic deletion of S1P1 in the endothelium did not alter the inflammatory response but led to increased colonic bleeding. Bacteria invaded into the wound beds, raising the possibility that microbes contributed to the observed changes in mucosal gene expression. In support of this, reducing bacterial abundance markedly attenuated the inflammatory response to wounding. Taken together, this study demonstrates the utility of the pinch biopsy model of colonic injury to elucidate the molecular underpinnings of colonic inflammation and its treatment. PMID- 30273601 TI - Intrauterine Programming of Glucocorticoid-Insulin-Like Growth Factor-1 Axis Mediated Developmental Origin of Osteoporosis Susceptibility in Female Offspring Rats with Prenatal Caffeine Exposure. AB - Epidemiologic investigations suggest that excessive intake of caffeine during pregnancy is one of the risk factors for osteoporosis in adult offspring. However, the phenomena and mechanisms have remained obscure. This study found that prenatal caffeine exposure (PCE) leads to persistent bone dysplasia in gestational day 20 and postnatal week 12 offspring rats and increases the susceptibility to osteoporosis in postnatal week 28 offspring rats. In the embryonic period, PCE increases the concentration of serum corticosterone and inhibits the expression of insulin-like growth factor-1 (IGF1) and osteogenic differentiation genes. After birth, the recovery of IGF1 expression in PCE offspring is unable to completely compensate osteogenic function, and chronic stress can lead to a further decrease in IGF1 expression. In vitro experiments found that corticosterone instead of caffeine restrains mineralized nodule formation and osteoblast differentiation by inhibiting IGF1 expression. The corticosterone inhibits H3K9 and H3K14 histone acetylation of IGF1 in osteoblasts through glucocorticoid receptor and CCAAT and enhancer binding protein alpha, respectively. In conclusion, glucocorticoid instead of caffeine inhibits bone IGF1 expression via glucocorticoid receptor and CCAAT and enhancer binding protein alpha and mediates the PCE-induced bone dysplasia and bone mass reduction in offspring fetal rats, which may contribute to osteoporosis susceptibility in adulthood. PMID- 30273603 TI - Reversing CXCL10 Deficiency Ameliorates Kidney Disease in Diabetic Mice. AB - The excessive accumulation of extracellular matrix material in the kidney is a histopathologic hallmark of diabetic kidney disease that correlates closely with declining function. Although considerable research has focused on the role of profibrotic factors, comparatively little attention has been paid to the possibility that a diminution in endogenous antifibrotic factors may also contribute. Among the latter, the ELR- CXC chemokines, CXCL9, CXCL10, and CXCL11, have been shown to provide a stop signal to prevent excessive fibrosis. Although the plasma concentrations of CXCL9 and CXCL11 were similar, those of CXCL10 were markedly lower in diabetic db/db mice compared with control db/m mice. In cell culture, CXCL10 inhibited kidney fibroblast collagen production in response to high glucose and the prosclerotic growth factor, transforming growth factor-beta. In vivo, recombinant murine CXCL10 reduced mesangial and peritubular matrix expansion, albuminuria, and glomerular hypertrophy in db/db mice. In bone marrow, a major source of circulating chemokines, the concentration of CXCL10 was lower in cells derived from diabetic mice than from their nondiabetic counterparts. Silencing of CXCR3, the cognate receptor for CXCL10, abrogated the antifibrotic effects of bone marrow-derived secretions. In conclusion, experimental diabetes is a state of CXCL10 deficiency and that restoration of CXCL10 abundance prevented fibrosis and the development of diabetic kidney disease in mice. PMID- 30273602 TI - High-Temperature Requirement A 1 Causes Photoreceptor Cell Death in Zebrafish Disease Models. AB - Age-related macular degeneration (AMD) is an important cause of blindness. It is characterized by a retinal pigment epithelium (RPE) disorder that leads to death of photoreceptor cells (PRCs). AMD has a strong genetic association with high temperature requirement A 1 (HTRA1). The relationship between HTRA1 and the AMD phenotype is unknown. In this study, we show that the expression of HTRA1 in PRCs, as well as in RPE, is increased by the disease-associated HTRA1 mutation and aging. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling assay and quantitative PCR of apoptosis-associated caspases confirmed that PRC specific overexpression of HTRA1 induced PRC death. Transgenic zebrafish overexpressing human HTRA1 in rod PRCs showed morphologic changes of the RPE, including PRC death and lipofuscin accumulation, features similar to those of early AMD. htra1 expression was also increased in a retinitis pigmentosa zebrafish model compared with wild type. In both fish lines, PRC death was rescued by the suppression of htra1 by the inhibitor 6-boroV. AKT-forkhead box O3 signaling downstream of HTRA1 was activated via a tumor growth factor beta signal, resulting in PRC death. These findings suggest that HTRA1 derived from PRCs is associated with early AMD via PRC death. HTRA1 is a potentially effective target for neuroprotective therapy of early AMD and other degenerative diseases of PRCs. PMID- 30273605 TI - Functional Role of microRNAs in the Progression of Breast Ductal Carcinoma in situ. AB - microRNAs (miRNAs) are small RNAs that influence gene expression by targeting messenger RNAs (mRNAs). Depending on the function of their target genes, miRNAs may regulate the expression of oncogenes and tumor suppressors, thereby contributing to the promotion or inhibition of tumor progression. Ductal carcinoma in situ (DCIS), although often diagnosed as breast cancer, is a potential precursor to invasive ductal carcinoma. Many of the genetic events required for the invasive progression of DCIS occur at the pre-invasive stage, and these events include changes to the expression of miRNAs. Aberrant expression of miRNAs can influence specific oncogenic or tumor suppressive pathways required for breast cancer progression. miRNAs in DCIS have been shown to influence hormone signaling, cell-cell adhesion, epithelial to mesenchymal transition, TGF beta signaling, maintenance of cancer stem cells, and modulation of the extracellular matrix. Additionally, extracellular DCIS miRNAs, such as those found in exosomes, may promote invasive progression by modifying the tumor microenvironment. Here, we review the miRNAs that have been identified in DCIS and how they may contribute to the progression to invasive disease. We also touch on the current state of miRNA therapeutic development, including the current challenges, and discuss the key future perspectives for research into miRNA function for the purpose of miRNA therapeutic development against DCIS. PMID- 30273604 TI - Human Placenta Expresses alpha2-Adrenergic Receptors and May Be Implicated in Pathogenesis of Preeclampsia and Fetal Growth Restriction. AB - alpha2-Adrenergic receptors (alpha2ARs) are G-protein-coupled receptors involved in catecholamine signaling by extracellular regulated protein kinase 1 and 2 (ERK1/2) pathways. We examined placental expression and function of alpha2AR subtypes in women with severe preeclampsia (sPE) with and without intrauterine growth restriction (IUGR). Placental biopsies were analyzed from 52 women with i) sPE (n = 8); ii) sPE + IUGR (n = 9); iii) idiopathic IUGR (n = 8); iv) idiopathic preterm birth (n = 16); and v) healthy term controls (n = 11). Expression of alpha2AR subtypes (alpha2A, alpha2B, alpha2C) and phospho-ERK1/2 (receptor activation marker) was investigated by immunohistochemistry and/or quantitative real-time RT-PCR. The effects of alpha2CAR knockdown on syncytialization (syncytin-1 and -2) and beta-human chorionic gonadotropin secretion were examined in BeWo cells stimulated with forskolin. The effects of alpha2AR agonist UK 14,304 and specific alpha2CAR antagonist were tested, using a trophoblast migration assay. All three alpha2ARs were expressed and functionally active in human placenta with site-specific localization. Highest alpha2BAR and alpha2CAR mRNA expression was identified in sPE + IUGR. alpha2CAR knockdown increased expression of syncytin-1 and -2 but decreased secretion of beta-human chorionic gonadotropin. UK 14,304 impaired trophoblast migration. The observed alpha2AR expression pattern suggests different function for each subtype. alpha2CAR modulates trophoblast syncytialization and migration and may carry pathogenic role in sPE + IUGR. PMID- 30273607 TI - Profile repeatability: A new method for evaluating repeatability of individual hormone response profiles. AB - There is broad interest in determining repeatability of individual responses. Current methods calculate repeatability of individual points (initial and/or peak), time to peak value, or a single measure of the integrated total response (area under the curve), rather than the shape of the response profile. Repeatability estimates of response profiles using linear mixed models (LMM) generate an average repeatability for an aggregate of individuals, rather than an estimate of individual repeatability. Here we use a novel ad hoc method to calculate repeatability of individual response profiles and demonstrate the need for a more rigorous assessment protocol. Response profile repeatability has not been defined at the individual level. We do this using a new metric, Profile Repeatability (PR), which incorporates components of variance and the degree to which response profiles cross each other in a time series. Values range from 0 (no repeatability) to 1 (complete repeatability). We created synthetic data to represent a range of apparent time series repeatability, and 20 independent observers visually ranked those data sets by degree of repeatability. We also applied the method to real data on stress responses of European starlings Sturnus vulgaris. We then computed PR scores for the synthetic data and for real data from European starling corticosterone responses over time, and contrast the results to those from LMM. Finally, we assessed the sensitivity of PR to reductions in the number of time points in the corticosterone response, as well as reductions in the number of replicates per individual. We found the average PR scores for a group of individuals to be somewhat robust to reductions in points in the time series; however, the ranks of individuals (PR values relative to one another) could change substantially with reduction in the number of values in a time series. PR showed threshold sensitivity to losing replicate time series between 6 and 4 replicates. Surprisingly, human observers fell into two disparate groups when ranking repeatability of the synthetic data, and the PR score indicated that human observers may underestimate repeatability of data where replicates cross each other. In contrast to the average profile repeatability estimated using LMMs, our approach calculates individual repeatability. From our perspective, LMM does not provide a definitive idea of repeatability at the individual level; in essence, it concludes that suites of time series with low within-individual variance has high repeatability, regardless of replicate trajectories. LMM and PR have non-linear relationships between 0 and 1, but PR has greater discrimination for mid-values of repeatability. Consistent average group repeatability can be associated with substantial differences in individual ranks suggests that estimating individual repeatability is critical. The PR score should be useful in comparing repeatability of any type of nonlinear, including non-monotonic, response profiles over time, which are common in both physiology and behavior, and it demonstrates the specific needs for future improvements of a profile repeatability metric. PMID- 30273606 TI - Adrenals Contribute to Growth of Castration-Resistant VCaP Prostate Cancer Xenografts. AB - The role of adrenal androgens as drivers for castration-resistant prostate cancer (CRPC) growth in humans is generally accepted; however, the value of preclinical mouse models of CRPC is debatable, because mouse adrenals do not produce steroids activating the androgen receptor. In this study, we confirmed the expression of enzymes essential for de novo synthesis of androgens in mouse adrenals, with high intratissue concentration of progesterone (P4) and moderate levels of androgens, such as androstenedione, testosterone, and dihydrotestosterone, in the adrenal glands of both intact and orchectomized (ORX) mice. ORX alone had no effect on serum P4 concentration, whereas orchectomized and adrenalectomized (ORX + ADX) resulted in a significant decrease in serum P4 and in a further reduction in the low levels of serum androgens (androstenedione, testosterone, and dihydrotestosterone), measured by mass spectrometry. In line with this, the serum prostate-specific antigen and growth of VCaP xenografts in mice after ORX + ADX were markedly reduced compared with ORX alone, and the growth difference was not abolished by a glucocorticoid treatment. Moreover, ORX + ADX altered the androgen dependent gene expression in the tumors, similar to that recently shown for the enzalutamide treatment. These data indicate that in contrast to the current view, and similar to humans, mouse adrenals synthesize significant amounts of steroids that contribute to the androgen receptor-dependent growth of CRPC. PMID- 30273608 TI - 3T Multiparametric MRI: Comparison of Performance With and Without Endorectal Coil for Prostate Cancer Detection, PI-RADSv2 Category and Staging with Whole Mount Histopathology Correlation in 429 Patients. AB - PURPOSE: To investigate performance of 3TmpMRI with and without endorectal coil (ERC) for detection of prostate cancer (PCa) with whole mount histopathology (WMHP) reference. MATERIALS AND METHODS: This retrospective HIPAA-compliant, IRB approved case-control study, included patients who underwent 3TmpMRI with and without ERC from 7/2009 to 12/2016, prior to prostatectomy. Tumor detection rate was calculated for total and index lesions. MRI and histopathology features of lesions were compared between two groups. P-value <0.05 was considered significant using SPSSv24. RESULTS: 871 WMHP lesions in 429 patients with a mean age of 61.8+/-7 were included. ERC and nonERC subcohorts comprised 260 and 169 patients with 529 and 342 lesions, respectively. Overall tumor detection rates for all, ERC and nonERC subcohorts were 49.6% (432/871), 50.5% (267/529) and 48.2% (165/342), respectively. Index tumor detection rates for overall, ERC and nonERC subcohorts were 77.6% (333/429), 78.5% (204/260) and 76.3% (129/169), respectively. The ERC and nonERC subcohorts detected 35.9% (66/184) and 48.4% (76/157) of anterior lesions (p =0.019), 58% (200/345) and 48.1% (89/185) of posterior lesions (p=0.025), 37.3% (41/110) and 54.4% (62/114) of transition lesions (p=0.010) and 53.7% (225/419) and 45.2% (103/228) of peripheral lesions (p=0.033). After adjusting for clinical and pathological factors, the ERC group only showed higher detection for peripheral and posterior PCa lesions. CONCLUSIONS: 3TmpMRI with and without ERC had similar detection for overall and index PCa. However, ERC subcohort had significantly higher detection of posterior and peripheral and lower detection of anterior and transition PCa lesions. PMID- 30273609 TI - Role of Residual Fragments on the Risk of Repeat Surgery After Flexible Ureteroscopy and Laser Lithotripsy: Single Center Study. AB - PURPOSE: To analyze the impact of residual stone fragments seen on abdominal X ray (KUB) after ureteroscopy and laser lithotripsy (URS) on the risk of repeat surgical intervention. MATERIALS AND METHODS: Our study included 781 patients (802 renal units) who had URS with laser lithotripsy, KUB within 3 months postoperatively and at least 1 year of follow-up. The URSs were performed using dusting technique. We analyzed the association between the surgical recurrence free survival and the size of the largest residual fragment. RESULTS: Over a median follow-up of 4.2 years repeat surgery was performed on 161 (20%) renal units. 75% of repeat interventions were performed for symptomatic nephrolithiasis. Postoperative imaging showed residual stone fragments in 42% of cases. In the entire group the risk of repeat surgery was increased in renal units with residual fragments >2 mm. The effect of the size of residual fragments on the risk of surgical recurrence varied by patient's body mass index (BMI) and was much larger in non-obese subjects who had increased risk of repeat surgery with residual fragments of any size. In the obese subgroup only >2 mm fragments increased the risk of surgical recurrence. CONCLUSIONS: The association between the size of residual stone fragments detected by post-URS KUB and the risk of repeat surgical intervention depends on patients' BMI. Non-obese patients with residual stone fragments of any size have increased risk of repeat intervention compared to those with negative KUB. The predictive value of post-URS KUB in obese patients is limited. PMID- 30273610 TI - A multi-amplicon 16S rRNA sequencing and analysis method for improved taxonomic profiling of bacterial communities. AB - Metagenomic sequencing of bacterial samples has become the gold standard for profiling microbial populations, but 16S rRNA profiling remains widely used due to advantages in sample throughput, cost, and sensitivity even though the approach is hampered by primer bias and lack of specificity. We hypothesized that a hybrid approach, that combined targeted PCR amplification with high-throughput sequencing of multiple regions of the genome, would capture many of the advantages of both approaches. We developed a method that identifies and quantifies members of bacterial communities through simultaneous analysis of multiple variable regions of the bacterial 16S rRNA gene. The method combines high-throughput microfluidics for PCR amplification, short read DNA sequencing, and a custom algorithm named MVRSION (Multiple 16S Variable Region Species-Level IdentificatiON) for optimizing taxonomic assignment. MVRSION performance was compared to single variable region analyses (V3 or V4) of five synthetic mixtures of human gut bacterial strains using existing software (QIIME), and the results of community profiling by shotgun sequencing (COPRO-Seq) of fecal DNA samples collected from gnotobiotic mice colonized with a defined, phylogenetically diverse consortium of human gut bacterial strains. Positive predictive values for MVRSION ranged from 65%-91% versus 44%-61% for single region QIIME analyses (p < .01, p < .001), while the abundance estimate r2 for MVRSION compared to COPRO-Seq was 0.77 vs. 0.46 and 0.45 for V3-QIIME and V4-QIIME, respectively. MVRSION represents a generally applicable tool for taxonomic classification that is superior to single-region 16S rRNA methods, resource efficient, highly scalable for assessing the microbial composition of up to thousands of samples concurrently, with multiple applications ranging from whole community profiling to targeted tracking of organisms of interest in diverse habitats as a function of specified variables/perturbations. PMID- 30273611 TI - Exercise-related resuscitated out-of-hospital cardiac arrest due to presumed myocardial ischemia: Result from coronary angiography and intravascular ultrasound. AB - AIM: Possible causes of exercise-related out-of-hospital cardiac arrest (OHCA) in people with coronary artery disease (CAD) include atherosclerotic plaque rupture (PR) and intra-coronary thrombosis, exercise-induced myocardial ischaemia and other triggers. We investigated whether there are differences in the incidence of PR and/or intra-coronary thrombus and in clinical outcome between 'exercise related' and 'non-exercise-related' OHCA. METHODS: 219 consecutive resuscitated patients with CAD diagnosed by emergency coronary angiography (CAG) were enrolled. They were divided into the exercise group (>=6 METs; n = 35) and non exercise group (<6 METs; n = 184), according to estimated METs immediately before OHCA using 2011 Compendium of Physical Activities. We investigated whether culprit lesions had PR and/or thrombus using CAG and intravascular ultrasound. The clinical outcome was 30-day survival with minimal neurologic impairment. RESULTS: Acute PR and/or thrombus occurred in fewer of the exercise group than the non-exercise group (11% vs. 90%; P < 0.001). The exercise group had a higher incidence of favorable neurological outcome (94% vs. 47%; P < 0.001) than the non exercise group. Multivariable Cox proportional hazards models revealed that exercise immediately before OHCA was one of the predictors of a good neurological outcome (HR, 0.19; P = 0.025). CONCLUSION: The incidence of PR and/or thrombosis was lower in the group taking higher levels of exercise, than in the group taking less or no exercise. "Exercise-related" OHCA with CAD has better clinical outcomes than "non-exercise-related" with a greater proportion of witnessed arrests and early return of spontaneous circulation. PMID- 30273612 TI - Low Intensity Pulsed Ultrasound Influences the Myogenic Differentiation of Muscle Satellite Cells in a Stress Urinary Incontinence Rat Model. AB - OBJECTIVE: To investigate the therapeutic effect of low intensity pulsed ultrasound (LIPUS) in a stress urinary incontinence (SUI) rat model and its influence on myogenic satellite cells. METHODS: Fifty Sprague-Dawley rats underwent vaginal distension and bilateral ovariectomy mimicking partum injury and menopause to construct SUI models, which were further randomized into 100 mW/cm2 LIPUS, 200 mW/cm2 LIPUS, 300 mW/cm2 LIPUS, and none-treatment control subgroups with 10 rats per subgroup. Ten rats served as mock operation control. Leak point pressure and bladder capacity were recorded 1 week after LIPUS treatment. Immunofluorescence staining and Western blot were performed to examine histological changes, myodifferentiation, and signaling pathway. RESULTS: Here,we found the leak point pressure and bladder capacity were restored in 200 mW/cm2 LIPUS and 300 mW/cm2 LIPUS groups, but not in 100 mW/cm2 LIPUS group. More robust striated muscle regeneration was observed in 200 mW/cm2 LIPUS group comparing with the SUI none-treatment group. Moreover, we found LIPUS activated the myodifferentiation of muscle satellite cells, which is correlated to p38 phosphorylation level. CONCLUSION: LIPUS restored the leak point pressure and bladder capacity, and activated satellite cell myodifferentiation in SUI rat model. PMID- 30273613 TI - A Prospective Accuracy Study of Prostate Imaging Reporting and Data System Version 2 on Multiparametric Magnetic Resonance Imaging in Detecting Clinically Significant Prostate Cancer With Whole-mount Pathology. AB - OBJECTIVE: To assess the accuracy of Prostate Imaging Reporting and Data System version 2 (PI-RADS v2) in detecting clinically significant prostate cancer (csPCa) on multiparametric magnetic resonance imaging (mpMRI) using whole-mount sections after radical prostatectomy (RP) as reference standard. METHODS: Forty eight patients undergoing mpMRI before RP were prospectively enrolled. Two experienced radiologists independently scored and mapped imaging findings according to PI-RADS v2. One experienced uropathologist mapped cancers detected on whole-mount sections using the PI-RADS v2 sector scheme. Per-lesion and per patient analyses were run. Primary outcomes were sensitivity and false discovery rate (FDR) in detecting csPCa using PI-RADS v2 score >=3 and >=4 as thresholds. Secondary outcome was inter-reader agreement. RESULTS: On the per-lesion analysis, sensitivity and FDR at the PI-RADS v2 threshold score >=3 were 0.75 and 0.17 for Reader 1, and 0.67 and 0.13 for Reader 2, respectively. At the PI-RADS v2 threshold score >=4, sensitivity was slightly lower, and FDR nearly halved for both readers. On the per-patient analysis, sensitivity for csPCa at the PI-RADS v2 threshold score >=3 was 0.85 for Reader 1, and 0.78 for Reader 2. At the PI RADS v2 threshold score >=4, sensitivity was slightly lower for both readers. Inter-reader agreement was substantial (k 0.72 and 0.65 for PI-RADS v2 threshold score >=3 and >=4, respectively). CONCLUSION: In our prospective study with pathology after RP as standard of reference, PI-RADS v2 showed good sensitivity in detecting csPCa on mpMRI with substantial agreement between 2 experienced readers. Threshold score >=4 had lower FDR. PMID- 30273614 TI - Spatial memory in young adults: Gender differences in egocentric and allocentric performance. AB - Spatial memory allows us to locate objects and organisms in space and move through the environment. We frequently use two strategies for this purpose: egocentric, related to the viewer's perspective, and allocentric, associated with environmental cues. This ability is usually assessed by 2D or virtual reality based tasks. Gender differences have been reported on these tasks. We designed two card-placing tasks with the aim of assessing egocentric and allocentric spatial memory in a real environment. This task makes it possible to separately compare egocentric and allocentric strategies, providing participants with 3D information naturally present in daily orientation activities. We will assess the performance of male and female young adults on the two strategies. Ninety-four subjects were recruited and performed egocentric and allocentric spatial memory card placing tasks. Spatial Span, forward and backward, was also assessed using the Cambridge Neuropsychological Assessment Battery (CANTAB), and the brief version of Benton's Judge of Line Orientation Test (JoLO) was used to evaluate the ability to judge spatial relations. Our results show that men outperformed women on both spatial memory tasks. Women performed better on Allocentric tasks than on Egocentric tasks, whereas men's scores did not show differences between strategies. Spatial memory performance on the card placing tasks was significantly correlated with performance on the backward visuospatial span from the CANTAB. This study supports the existence of gender differences in spatial memory functioning, and it provides novel tools for the neuropsychological assessment of spatial memory. PMID- 30273615 TI - Coarse-grained dynamics of supramolecules: Conformational changes in outer shells of Dengue viruses. AB - While structural data on viruses are more and more common, information on their dynamics is much harder to obtain as those viruses form very large molecular complexes. In this paper, we propose a new method for computing the coarse grained normal modes of such supra-molecules, NormalGo. A new formalism is developed to represent the Hessian of a quadratic potential using tensor products. This formalism is applied to the Tirion elastic potential, as well as to a Go like potential. When combined with a fast method for computing a select set of eigenpairs of the Hessian, this new formalism enables the computation of thousands of normal modes of a full viral shell with more than one hundred thousand atoms in less than 2 h on a standard desktop computer. We then compare the two coarse-grained potentials. We show that, despite significant differences in their formulations, the Tirion and the Go like potentials capture very similar dynamics characteristics of the molecule under study. However, we find that the Go like potential should be preferred as it leads to less local deformations in the structure of the molecule during normal mode dynamics. Finally, we use NormalGo to characterize the structural transitions that occur when FAB fragments bind to the icosahedral outer shell of serotype 3 of the Dengue virus. We have identified residues at the surface of the outer shell that are important for the transition between the FAB-free and FAB-bound conformations, and therefore potentially useful for the design of antibodies to Dengue viruses. PMID- 30273616 TI - Chronic whole-body heat treatment relieves atherosclerotic lesions, cardiovascular and metabolic abnormalities, and enhances survival time restoring the anti-inflammatory and anti-senescent heat shock response in mice. AB - Unhealthy lifestyle persistently feeds forward inflammation in metabolic organs thus imposing senescence-associated secretory phenotype (SASP), as observed in obesity and type 2 diabetes. However, SASP blocks physiological resolution of inflammation by suppressing the anti-inflammatory and anti-senescent heat shock (HS) response, i.e., the gene program centered in heat shock factor-1 (HSF1) dependent expression heat shock proteins (HSPs). As SASP-inducing factors are not removed, leading to the perpetuation of inflammation, we argued that SIRT1-HSF1 HSP axis might also be suppressed in atherosclerosis, which could be reversible by heat treatment (HT), the most powerful HS response trigger. LDLr-/- adult mice were fed on high-fat/high-cholesterol diet from the age of 90 days until the end of study (age of 270 days). After 120 days under atherosclerotic diet, the animals were submitted to either whole-body HT (n = 42; 40 degrees C) or sham (n = 59; 37 degrees C) treatment (15 min/session), under anesthesia, once a week, for 8 weeks, being echographically and metabolically monitored. Aortic expressions of SIRT1, HSF1, HSP27, HSP72 and HSP73 were progressively depressed in atherosclerotic animals, as compared to normal (LDLr+/+; n = 25) healthy counterparts, which was paralleled by increased expression of NF-kappaB-dependent VCAM1 adhesion molecule. Conversely, HT completely reversed suppression of the above HS response proteins, while markedly inhibiting both VCAM1 expression and NF-kappaB DNA-binding activity. Also, HT dramatically reduced plasma levels of TG, total cholesterol, LDL-cholesterol, oxidative stress, fasting glucose and insulin resistance while rising HDL-cholesterol levels. HT also decreased body weight gain, visceral fat, cellular infiltration and aortic fatty streaks, and heart ventricular congestive hypertrophy, thereby improving aortic blood flow and myocardial performance (Tei) indices. Remarkably, heat-treated mice stopped dying after the third HT session (= 8 human years), suggesting a curative effect. Therefore, evolution of atherosclerosis is associated with suppression of the anti-inflammatory and anti-senescent SIRT1-HSF1-HSP molecular axis, which is refreshed by chronic heat treatment. PMID- 30273617 TI - Animal models for analysis of immunological responses to nanomaterials: Challenges and considerations. AB - Nanotechnology provides many solutions to improve conventional drug delivery and has a unique niche in the areas related to the specific targeting of the immune system, such as immunotherapies and vaccines. Preclinical studies in this field rely heavily on the combination of in vitro and in vivo methods to assess the safety and efficacy of nanotechnology platforms, nanoparticle-formulated drugs, and vaccines. While certain types of toxicities can be evaluated in vitro and good in vitro-in vivo correlation has been demonstrated for such tests, animal studies are still needed to address complex biological questions and, therefore, provide a unique contribution to establishing nanoparticle safety and efficacy profiles. The genetic, metabolic, mechanistic, and phenotypic diversity of currently available animal models often complicates both the animal choice and the interpretation of the results. This review summarizes current knowledge about differences in the immune system function and immunological responses of animals commonly used in preclinical studies of nanomaterials. We discuss challenges, highlight current gaps, and propose recommendations for animal model selection to streamline preclinical analysis of nanotechnology formulations. PMID- 30273618 TI - Fixation probabilities and hitting times for low levels of frequency-dependent selection. AB - In population genetics, diffusions on the unit interval are often used to model the frequency path of an allele. In this setting we derive approximations for fixation probabilities, expected hitting times and the expected frequency spectrum for low levels of frequency-dependent selection. Specifically, we rederive and extend the one-third rule of evolutionary game theory (Nowak et al., 2004) and effects of stochastic slowdown (Altrock and Traulsen, 2009). Since similar effects are of interest in other application areas, we formulate our results for general one-dimensional diffusions. PMID- 30273619 TI - Dynamic suspension culture improves ex vivo expansion of cytokine-induced killer cells by upregulating cell activation and glucose consumption rate. AB - Ex vivo expansion is an effective strategy to acquire cytokine-induced killer (CIK) cells needed for clinical trials. In this work, the effects of dynamic suspension culture, which was carried out by shake flasks on a shaker, on CIK cells were investigated by the analysis of expansion characteristics and physiological functions, with the objective to optimize the culture conditions for ex vivo expansion of CIK cells. The results showed that the expansion folds of total cells in dynamic cultures reached 69.36 +/- 30.36 folds on day 14, which were significantly higher than those in static cultures (9.24 +/- 1.12 folds, P < 0.05), however, the proportions of CD3+ cells and CD3+CD56+ cells in both cultures were similar, leading to much higher expansion of CD3+ cells and CD3+CD56+ cells in dynamic cultures. Additionally, expanded CIK cells in two cultures possessed comparable physiological functions. Notably, significantly higher percentages of CD25+ cells and CD69+ cells were found in dynamic cultures (P < 0.05). Besides, much higher glucose consumption rate of cells (P < 0.05) but similar YLac/gluc were observed in dynamic cultures. Further, cells in dynamic cultures had better glucose utilization efficiency. Together, these results suggested that dynamic cultures improved cell activation, then accelerated glucose consumption rate, which enhanced cell expansion and promoted glucose utilization efficiency of cells. PMID- 30273620 TI - Hypothesis-driven weight-of-evidence analysis for the endocrine disruption potential of benzene. AB - Exposure to benzene has many sources, from gasoline refueling to tobacco combustion. Although the toxicology of benzene is well studied, the potential for environmental exposure and a heightened interest in identifying substances that may cause toxicity by interacting with the endocrine systems of humans and wildlife resulted in benzene being placed on the second list of chemicals for possible screening under the USEPA's Endocrine Disruptor Screening Program. Therefore, we conducted a thorough, systematic literature search and used a weight-of-evidence methodology to test hypotheses regarding the potential for benzene to act via estrogen, androgen, thyroid, and steroidogenic pathways. The methodology included an assessment of data quality and a semi-quantitative weighting of endocrine-responsive endpoints measured in various types of studies according to their relevance for evaluating each hypothesis. This maximized use of all relevant and reliable literature on benzene and enabled a transparent comparison of evidence supporting and opposing each hypothesized mode of action. While benzene affected reproductive organ weights and histopathology in a few studies, there was no consistent pattern of effects suggestive of an estrogen, androgen, thyroid or steroidogenic mode of action. Based on data from multiple animal species, benzene appears to lack endocrine activity by these pathways. PMID- 30273621 TI - Cost-Effectiveness Analysis of Descemet's Membrane Endothelial Keratoplasty Versus Descemet's Stripping Endothelial Keratoplasty in the United States. AB - PURPOSE: To determine the cost-effectiveness of Descemet's membrane endothelial keratoplasty (DMEK) compared with Descemet's stripping automated endothelial keratoplasty (DSAEK) in the United States. DESIGN: Cost-effectiveness analysis in a surgical center in the United States. PARTICIPANTS: Binocular adult patient undergoing endothelial keratoplasty. METHODS: A base case of a 70-year-old man undergoing his first endothelial keratoplasty for bilateral Fuchs' endothelial dystrophy. The cost-effectiveness of DMEK was compared with DSAEK over a 15-year time horizon. The incidences and costs of complications were derived from PubMed English literature searches, Medicare reimbursements, and average wholesale prices. All costs were discounted 3% per annum and adjusted for inflation to 2018 U.S. dollars. Uncertainty was evaluated using deterministic and probabilistic sensitivity analyses. MAIN OUTCOME MEASURES: Incremental cost-effectiveness ratios and incremental cost-utility ratios, measured in cost per quality-adjusted life-years (QALYs). RESULTS: Performing a DMEK instead of a DSAEK generated an extra 0.4 QALYs over a 15-year period. From a societal and third-party payer perspective, DMEK was cost-saving when compared with DSAEK in improving visual acuity in the base case. Probabilistic sensitivity analyses with variations in the costs and rebubble rates revealed that DMEK was cost-saving compared with DSAEK in 38% of iterations and was within a societal willingness-to-pay threshold of $50 000 in 98% of models. CONCLUSIONS: From the societal and third-party payer perspectives in the United States, DMEK generated greater utilities and was less costly than DSAEK. Therefore, DMEK was the dominant procedure and was cost-saving with respect to DSAEK. The economic model was robust based on sensitivity analyses.

PMID- 30273622 TI - Are Patient Self-Reported Outcome Measures Sensitive Enough to Be Used as End Points in Clinical Trials?: Evidence from the United Kingdom Glaucoma Treatment Study. AB - PURPOSE: The United Kingdom Glaucoma Treatment Study (UKGTS) demonstrated the effectiveness of an intraocular pressure-lowering drug in patients with glaucoma using visual field progression as a primary outcome. The present study tested the hypothesis that responses on patient-reported outcome measures (PROMs; secondary outcome measure) differ between patients receiving a topical prostaglandin analog (latanoprost) or placebo eye drops in UKGTS. DESIGN: Multicenter, randomized, triple-masked, placebo-controlled trial. PARTICIPANTS: Newly diagnosed glaucoma patients in the UKGTS with baseline and exit PROMs (n = 182 and n = 168 patients from the treatment and placebo groups, respectively). METHODS: In the UKGTS (trial registration number, ISRCTN96423140), patients with open-angle glaucoma were allocated to receive latanoprost (treatment) or placebo; the observation period was 24 months. Patients completed general health PROMs (European Quality of Life in 5 Dimensions [EQ-5D] and 36-item Short Form [SF-36]) and PROMs specific to glaucoma (15-item Glaucoma Quality of Life [GQL-15] and 9-item Glaucoma Activity Limitation [GAL-9]) at baseline and exit from the trial. Percentage changes between measurement on PROMs were calculated for each patient and compared between treatment arms. In addition, differences between stable patients (n = 272) and those with glaucomatous progression (n = 78), as determined by visual field change (primary outcome), were assessed. MAIN OUTCOME MEASURE: PROMs on health-related and vision-related quality of life. RESULTS: Average percentage change on PROMs was similar for patients in both arms of the trial, with no statistically significant differences between treatment and placebo groups (EQ-5D, P = 0.98; EQ-5D visual analog scale, P = 0.88; SF-36, P = 0.94, GQL-15, P = 0.66; GAL-9, P = 0.87). There were statistically significant differences between stable and progressing patients on glaucoma-specific PROMs (GQL-15, P = 0.02; GAL-9, P = 0.02), but not on general health PROMs (EQ-5D, P = 0.62; EQ-5D visual analog scale, P = 0.23; SF-36, P = 0.65). CONCLUSIONS: Average change in PROMs on health-related and vision-related quality of life was similar for the treatment and placebo groups in the UKGTS. The PROMs used may not be sensitive enough to function as primary end points in clinical trials when participants have newly diagnosed early-stage glaucoma. PMID- 30273624 TI - Evolutionary Divergence of Brain-specific Precursor miRNAs Drives Efficient Processing and Production of Mature miRNAs in Human. AB - The hallmark of human evolution encompasses the dramatic increase in brain size and complexity. The intricate interplays of micro-RNAs (miRNAs) and their target genes are indispensable in brain development. Sequence divergence in distinct structural regions of Brain-specific precursor miRNAs (pre-miRNAs) and its consequence in the production of corresponding mature miRNAs in human are unknown. To address these questions, first we classified miRNAs into three categories based on tissue expression: Brain-specific (expressed exclusively in brain), Non-brain (expressed in Non-brain tissues) and Common (expressed in all tissues) and compared the sequence divergence of different structural regions (basal segment, lower and upper stem, internal and terminal loop) of categorized pre-miRNAs across human, non-human primates and rodents. Our analysis revealed that unpaired regions of Brain-specific pre-miRNAs in human bear traces of relatively high rate of evolutionary divergence compared to those in other species. Cross-tissue expression analysis unveiled the higher expression of the Brain-specific miRNAs in human compared to other species. Intriguingly, in human brain, expression levels of these miRNAs superseded the levels of the ubiquitously expressed "Common-miRNAs". Further analysis revealed that presence of certain motif and nucleotide preference in the Brain-specific pre-miRNAs may favor DROSHA and DICER to ameliorate miRNA processing. The higher processing efficiency of human Brain-specific miRNAs was reflected as an elevated production of corresponding mature miRNAs in the human brain. Finally, re-construction of gene-regulatory network uncovers different pathways driven by Brain-specific miRNAs that may contribute to the development of brain in human. PMID- 30273625 TI - New Insight into the Mechanism of Mannitol Effects on Cerebrospinal Fluid Pressure Decrease and Craniospinal Fluid Redistribution. AB - Intracranial hypertension, which often follows a severe brain injury, is usually treated with intravenous (i.v.) application of hyperosmolar solutions. The mechanism of intracranial cerebrospinal fluid (CSF) pressure decrease after such a treatment is still unclear. The aim of this article was to try to explain the mechanism of CSF pressure reduction after i.v. hyperosmolar mannitol bolus in regard to the changes in CSF volume. Two types of experiments were done on anesthetized cats before and after hyperosmolar mannitol application: ventriculo cisternal perfusion at different perfusion rates, simultaneously measuring the perfusate outflow volume, and CSF pressure recording in the lateral ventricle before and during artificial CSF infusion. Mannitol application in the first group of cats significantly reduced collected prefusate volume during ventriculo cisternal perfusion, and in the second group it prevented CSF pressure increase caused by artificial CSF infusion. Our results strongly suggest that the mechanism of hyperosmolar mannitol action after its i.v. application is based on osmotic fluid retrieval from interstitial and cerebrospinal compartments into the microvessels. This shift, without significant volume change inside the cranium, causes a predominant decrease of CSF volume in the spinal part of the system, which in turn leads to lowering of the CSF pressure. Spinal CSF volume decrease is enabled by the extensibility of the spinal dura, this way providing the possibility for CSF volume redistribution inside the CSF system, together with CSF pressure decrease. This mechanism of mannitol action is in accordance with the new hypothesis of CSF physiology. PMID- 30273626 TI - Mesolimbic connectivity signatures of impulsivity and BMI in early adolescence. AB - Across age groups, differences in connectivity of the mesolimbic and the prefrontal cortex co-vary with trait impulsivity and sensation-seeking. Impulsivity and sensation-seeking are also known to increase during early adolescence as maturation of subcortical structures outpaces that of the prefrontal cortex. While an imbalance between the striatum and prefrontal cortex is considered a normal developmental process, higher levels of adolescent impulsivity and sensation-seeking are associated with an increased risk for diverse problems, including obesity. To determine how the relationship between sensation-seeking, impulsivity and body mass index (BMI) is related to shared neural correlates we measured their relationships with the connectivity of nuclei in the striatum and dopaminergic midbrain in young adolescents. Data were collected from 116 children between the ages of 12 and 14, and included resting state functional magnetic resonance imaging, personality measures from the Substance Use Risk Profile Scale, and BMI Z-score for age. The shared variance for the connectivity of regions of interest in the substantia nigra, ventral tegmental area, ventral striatum and sub-thalamic nucleus, personality measures and BMI Z-score for age, were analyzed using partial least squares correlation. This analysis identified a single significant striato-limbic network that was connected with the substantia nigra, ventral tegmental area and sub-thalamic nuclei (p = 0.002). Connectivity within this network which included the hippocampi, amygdalae, parahippocampal gyri and the regions of interest, correlated positively with impulsivity and BMI Z-score for age and negatively with sensation-seeking. Together, these findings emphasize that, in addition to the well-established role that frontostriatal circuits play in the development of adolescent personality traits, connectivity of limbic regions with the striatum and midbrain also impact impulsivity, sensation-seeking and BMI Z-score in adolescents. PMID- 30273627 TI - Nitric oxide and l-arginine regulate feeding in satiated rats. AB - Nitric Oxide (NO) and its precursor l-arginine were found to inhibit feeding in rats with a low motivation to eat, as they do in Aplysia. In rats that are relatively satiated, treatment with an NO blocker increased feeding, and treatment with an NO donor or with either of 2 doses of l-arginine inhibited feeding. NO and l-arginine modulated several parameters of feeding, such as the total duration of appetitive behaviors, the time spent feeding, the quantity of food eaten and the number of feeding bouts. The inhibitory effect of l-arginine on feeding could not be attributed to changes in locomotion. These data indicate that satiation is partially mediated by increased production of NO. NADPH Diaphorase histochemical staining, which is specific for tissues actively producing NO, showed significantly greater staining in satiated compared to hungry rats in all 4 hypothalamic nuclei (paraventricular and arcuate nuclei, lateral and ventromedial hypothalamus) that were examined. l-arginine may act as a regulator of feeding by controlling NO production in several hypothalamic nuclei, specifically under condition of a low feeding motivation. PMID- 30273628 TI - Gulf War agents pyridostigmine bromide and permethrin cause hypersensitive nociception that is restored after vagus nerve stimulation. AB - Gulf war illness (GWI) is a chronic multi-symptom disease that afflicts 25-33% of troops that were deployed in the 1990-1991 Gulf War. GWI symptoms include cognitive, behavioral and emotional deficits, as well as migraines and pain. It is possible that exposure to Gulf War agents and prophylactics contributed to the reported symptomology. Pyridostigmine bromide (PB) and permethrin (PER) were given to protect from nerve gas attacks and insect vector born disease, respectively. Previous studies have demonstrated that 10 days of exposure to these chemicals can cause symptoms analogous to those observed in GWI, including impairment of long-term memory in mice. Other studies using this model have shown chronic neuroinflammation, and chronic neuroinflammation can lead to altered nociceptive sensitivity. At 10-weeks after the 10-day PB and PER exposure paradigm, we observed lowered nociceptive threshold on the Von Frey test that was no longer evident at 28 weeks and 38 weeks post-exposure. We further determined that vagus nerve stimulation, initiated at 38 weeks after exposure, restores the lowered nociceptive sensitivity. Therefore, stimulating the vagus nerve appears to influence nociception. Future studies are need to elucidate possible mechanisms of this effect. PMID- 30273629 TI - Fluoride activates microglia, secretes inflammatory factors and influences synaptic neuron plasticity in the hippocampus of rats. AB - Epidemiological studies have reported that highly fluoridated drinking water may significantly decrease the Intelligence Quotient (IQ) of exposed children. It is thought that synaptic plasticity is the basis of learning and memory skills in developing children. However, the effect on synaptic plasticity by activated microglia induced via fluoride treatment is less clear. Our previous research showed that fluoride ions activated microglia which then released pro inflammatory cytokines. In this study, hippocampal-dependent memory status was evaluated in rat models sub-chronically exposed to fluoride in their drinking water. Microglial activation in the hippocampus was examined using immunofluorescence staining and the expression of synaptophysin (SYP) and postsynaptic density protein 95 (PSD-95), Long-term potentiation (LTP) and the expression of Amino-3-hydroxy-5-methy-4-isoxazole propionate (AMPA) receptor subunit GluR2 as well as N-methyl-d-aspartate (NMDA) receptor subunit NMDAR2beta of exposed rats. We found that fluoride exposure activated microglia and increased the expression of DAP12 and TREM2, as well as promoted pro-inflammatory cytokines secretion via ERK/MAPK and P38/MAPK signal pathways. Furthermore fluoride depressed LTP and decreased PSD-95 protein levels as well as expression of ionotropic glutamate receptors GluR2 and NMDAR2beta. We concluded that the role of fluoride on synaptic plasticity may be associated with neuroinflammation induced by microglia. PMID- 30273630 TI - The alternatively spliced porcine FcgammaRI regulated PRRSV-ADE infection and proinflammatory cytokine production. AB - Receptors for the Fc region of IgG (FcgammaRs) play a key role in protecting the immune system and host from infection. In this study, we described the cloning, sequencing and characterization of porcine FcgammaRI, and reported six different FcgammaRI isoforms, four of which have never been reported before. Further analysis revealed that FcgammaR isoforms are generated by alternative splicing mechanisms, including two membrane isoforms and four soluble isoforms. Importantly, we found FcgammaRI splice variants differentially influence PRRSV antibody-dependent enhancement (ADE) effects. Membrane pCD64-T1 promotes endocytosis of the PRRSV-antibody complex to enhance PRRSV replication, and soluble pCD64-T3 has no ADE effect on PRRSV proliferation, but shows an inflammation enhancement effect. The differential expression of selective splicing in primary PAM cells and 3D4/21 cell lines are altered and regulated by PRRSV infection and inflammatory environment. Our results indicated that porcine FcgammaRI plays dual regulatory roles in PRRSV multiplication and PRRSV inflammation process by the alternatively spliced mechanism, which will be a new target in PRRSV prevention and control. PMID- 30273631 TI - Carotid webs and ischemic stroke: Experiences in a comprehensive stroke center. AB - BACKGROUND AND PURPOSE: Carotid webs are intraluminal filling defects at the carotid bulb which are considered rare, though possibly underappreciated entities with recent studies demonstrating a likely casual association with ischemic stroke. The purpose of the study is to describe our recent experience with clinical and imaging manifestations of carotid webs. MATERIALS AND METHODS: A retrospective review of CTA neck studies in all adult patients presenting to our institution during the 19-month study interval was performed to determine the presence of carotid webs. Subsequent chart review of these patients with webs was performed to assess their clinical history and to obtain demographic detail. RESULTS: A total of 14 patients were identified with carotid webs in the study population. The mean age of patients with webs was 42.1 years (range: 28-54), consisting mostly of African Americans (86%) and females (64%). Ten (71%) of web patients had a history of ischemic stroke, each ipsilateral to the side of web, and at least four of these patients had recurrent ischemic stroke. CONCLUSION: We provide one of the largest sample sizes of webs gathered in a single study. Given its association with ischemic stroke, carotid webs should be assessed for in all patients presenting with ischemic stroke, especially younger African Americans. PMID- 30273632 TI - Review on rosmarinic acid extraction, fractionation and its anti-diabetic potential. AB - Rosmarinic acid is a bioactive phytochemical that can be found in many herbs as ethnomedicines. It possesses remarkable pharmacological activities, and thus leading to its exploration as a therapeutic drug in diabetes treatment recently. This article reviews the extraction and fractionation techniques for plant-based natural rosmarinic acid and its anti-diabetic potential based on literature data published in journals, books, and patents from 1958 to 2017. Factors affecting the performance of rosmarinic acid extraction and fractionation such as operating temperature, time, solvent to sample ratio and eluent system are compiled and discussed in detail. The inhibitory action of rosmarinic acid against sugar digestive enzymes, and protective action towards pancreatic beta-cell dysfunction and glucolipotoxicity mediated oxidative stress are also critically reviewed. The optimal parameters are largely dependent on the applied extraction and fractionation techniques, as well as the nature of plant samples. Previous studies have proven the potent role of rosmarinic acid to control plasma glucose level and increase insulin sensitivity in hyperglycemia. Although rosmarinic acid is readily absorbed by human body, its mechanism after consumption is remained unclear. Intensive studies should be well planned to determine the dosage and toxicity level of rosmarinic acid for efficacy and safe consumption. PMID- 30273633 TI - A likely placental barrier against methylmercury in pregnant rats exposed to fish containing diets. AB - Methylmercury (MeHg) taken up through fish consumption can be transferred from the mother to the fetus during pregnancy. In the present study, pregnant rat mothers were contaminated with environmentally relevant doses of 36 and 76 ng MeHg/g of food using diets containing naturally mercury-containing fish. Young female rats fed with fish-containing food after weaning showed decreased locomotion in Y maze for accumulated concentrations in brain as low as 75 ng Hg/g dry weight (15 ng Hg/g wet weight). Young female rats fed the control diet after weaning yet borne by mothers fed the diet containing 76 ng MeHg/g, presented a 58% reduced activity in the open-field labyrinth, meaning that the maternal exposure to fish-containing food exerted an effect in utero that lasted several weeks after birth. Newborns were protected against Hg exposure by the placental barrier since in newborns from mothers fed the diet containing 76 ng MeHg/g of food, the concentrations of Hg in brain, kidney, liver and skeletal muscles represented 12, 3, 21 and 18% of those of their mother's tissues, respectively. These results suggest the existence, at least in rats, of a threshold level in terms of MeHg exposure above which the placental barrier collapses. PMID- 30273634 TI - Healthy play, better coping: The importance of play for the development of children in health and disease. AB - Play is of vital importance for the healthy development of children. From a developmental perspective, play offers ample physical, emotional, cognitive, and social benefits. It allows children and adolescents to develop motor skills, experiment with their (social) behavioural repertoire, simulate alternative scenarios, and address the various positive and negative consequences of their behaviour in a safe and engaging context. Children with a chronic or life threatening disease may face obstacles that negatively impact play and play development, possibly impeding developmental milestones, beyond the actual illness itself. Currently, there is limited understanding of the impact of (1) aberrant or suppressed play and (2) play-related interventions on the development of chronic diseased children. We argue that stimulating play behaviour enhances the adaptability of a child to a (chronic) stressful condition and promotes cognitive, social, emotional and psychomotor functioning, thereby strengthening the basis for their future health. Systematic play research will help to develop interventions for young patients, to better cope with the negative consequences of their illness and stimulate healthy development. PMID- 30273635 TI - Vesicular glutamate transporter isoforms: The essential players in the somatosensory systems. AB - In nervous system, glutamate transmission is crucial for centripetal conveyance and cortical perception of sensory signals of different modalities, which necessitates vesicular glutamate transporters 1-3 (VGLUT 1-3), the three homologous membrane-bound protein isoforms, to load glutamate into the presysnaptic vesicles. These VGLUTs, especially VGLUT1 and VGLUT2, selectively label and define functionally distinct neuronal subpopulations at each relay level of the neural hierarchies comprising spinal and trigeminal sensory systems. In this review, by scrutinizing each structure of the organism's fundamental hierarchies including dorsal root/trigeminal ganglia, spinal dorsal horn/trigeminal sensory nuclear complex, somatosensory thalamic nuclei and primary somatosensory cortex, we summarize and characterize in detail within each relay the neuronal clusters expressing distinct VGLUT protein/transcript isoforms, with respect to their regional distribution features (complementary distribution in some structures), axonal terminations/peripheral innervations and physiological functions. Equally important, the distribution pattern and characteristics of VGLUT1/VGLUT2 axon terminals within these structures are also epitomized. Finally, the correlation of a particular VGLUT isoform and its physiological role, disclosed thus far largely via studying the peripheral receptors, is generalized by referring to reports on global and conditioned VGLUT knockout mice. Also, researches on VGLUTs relating to future direction are tentatively proposed, such as unveiling the elusive differences between distinct VGLUTs in mechanism and/or pharmacokinetics at ionic/molecular level, and developing VGLUT-based pain killers. PMID- 30273636 TI - Fluid model of epithelial morphogenesis: Oscillations and structuring. AB - We have revised a mathematical model of epithelial morphogenesis by Belintsev et al. (1987) (BB model) taking into account the oscillatory nature of morphogenesis and stability analysis (Cherdantsev, 2014). Following the BB model in considering the feedback control of cell shape changes by mechanical forces, we modify it to represent epithelial surface movements observed in different types of Metazoan gastrulation. Basing on these observations, we argue that the epithelial surface movement is that of an incompressible fluid supplemented by a positive feedback between the movement and spreading of the surface flow. Dipole interactions between sources and sinks of surface energy provide a single mechanism both of short-ranged and long-ranged regulation of collective cell and surface movements whose basic variables are the space averaged epithelial surface curvature and lateral pressure within the epithelial surface flux negatively related to its velocity. The short-ranged activation means a movement of the surface up to the lateral pressure gradient under non-linear feedback control of the surface flexure. The break of this feedback with equalization of the surface curvature is sufficient for a self-restriction of the movement spreading. Owing to bistable interdependence between the lateral pressure and epithelial surface curvature, we get a generic oscillatory contour in which the same region oscillates being alternately a sink and source of the surface flow. The opposite phase oscillations of the lateral pressure and curvature allow for both directional propulsion of the surface through the same region and spatial differentiation based on parametric differences between the large-scaled regions that correspond to sources and sinks of the surface. PMID- 30273637 TI - Stress-generating tissue deformations in Xenopus embryos: Long-range gradients and local cell displacements. AB - BACKGROUND: Although the role of endogenous mechanical stresses in regulating morphogenetic movements and cell differentiation is now well established, many aspects of mechanical stress generation and transmission in developing embryos remain unclear and require quantitative studies. RESULTS: By measuring stress bearing linear deformations (caused by differences in cell movement rates) in the outer cell layer of blastula - early tail-bud Xenopus embryos, we revealed a set of long-term tension-generating gradients of cell movement rates, modulated by short-term cell-cell displacements much increasing the rates of local deformations. Experimental relaxation of tensions distorted the gradients but preserved and even enhanced local cell-cell displacements. During development, an incoherent mode of cell behavior, characterized by extensive cell-cell displacements and poorly correlated cell trajectories, was exchanged for a more coherent regime with the opposite characteristics. In particular, cell shifts became more synchronous and acquired a periodicity of several dozen minutes. CONCLUSIONS: Morphogenetic movements in Xenopus embryos are mediated by mechanically stressed dynamic structures of two different levels: extended gradients and short-term cell-cell displacements. As development proceeds, the latter component decreases and cell trajectories become more correlated. In particular, they acquire common periodicities, making morphogenesis more coherent. PMID- 30273638 TI - Cerebrospinal fluid collection in laboratory mice: Literature review and modified cisternal puncture method. AB - BACKGROUND: The composition of cerebrospinal fluid (CSF) is an invaluable parameter in better understanding of cellular and molecular processes within the mammalian brain. However, the collection of significant volumes of clean CSF can be technically challenging in studies with laboratory mice. Over the past five decades, several approaches have been developed to maximize the quantity and quality of CSF samples, either from live or euthanized animals. Due to the small amounts collected, samples from single mice were often pooled or diluted to meet volume requirements of automated counters and multiple assays. NEW METHOD: This paper reviews previous work on CSF collection in mice, thus providing methodological background for the current post-mortem procedure. This modified cisternal puncture method involves the use of a peristaltic pump for consistent and slow intracardiac perfusion, as well as a loupe headset with a custom-made glass pipette for piercing a single hole in the atlanto-occipital membrane during repeated CSF draws. Sample cleanness is verified by comparing the colour of the glass pipette and the bottom of centrifuged PCR vial against a white background. RESULTS: With three trained experimenters, the entire procedure (including anesthesia) takes ~11-13 min and often results in the collection of up to 40 MUl of clean CSF from males of different murine strains. Properly staggered collections allow processing of relatively large cohorts of mice per day. CONCLUSIONS: This modification of previously employed methods can be used in studies that require tightly-timed collections of larger volumes of undiluted, tissue-free CSF and/or individual data records. PMID- 30273639 TI - Impact of test protocols and material binding on the efficacy of antimicrobial wipes. AB - BACKGROUND: The use of effective cleaning/disinfectant products is important to control pathogens on healthcare surfaces. With the increasing number of wipe products available, there is a concern that combination of a formulation with the wrong material will decrease the efficacy of the product. This study aimed to use a range of efficacy test protocols to determine the efficacy of four formulations before and after binding to three commonly used wiping materials. METHODS: Two quaternary ammonium (QAC)-based products, one hydrogen-peroxide-based product and one neutral cleaner were combined with microfibre, cotton or non-woven materials and tested for efficacy against Pseudomonas aeruginosa and Staphylococcus aureus with two surface tests (ASTM E2197-17 and EN13697-15) and two 'product' tests (ASTM E2967-15 and EN16615-15). FINDINGS: Overall, the impact of using different materials on formulation efficacy was limited, except for an alkyl(C12 16)dimethylbenzylammonium chloride-based product used at 0.5% v/v. The hydrogen peroxide product was the most efficacious regardless of the material used. The results from wipe test ASTM E2967-15 were consistent with those from the surface tests, but not with EN16615-15 which was far less stringent. CONCLUSIONS: The use of different wiping cloth materials may not impact severely on the efficacy of potent disinfectants, despite the absorption of different volumes of formulation by the materials. QAC-based formulations may be at higher risk when a low concentration is used. There were large differences in efficacy depending on the standard test performed, highlighting the need for more stringency in choosing the test to make a product claim on label.

PMID- 30273641 TI - Gateway reflex: Local neuroimmune interactions that regulate blood vessels. AB - Neuroimmunology is a research field that intersects neuroscience and immunology, with the larger aim of gaining significant insights into the pathophysiology of chronic inflammatory diseases such as multiple sclerosis. Conventional studies in this field have so far mainly dealt with immune responses in the nervous system (i.e. neuroinflammation) or systemic immune regulation by the release of glucocorticoids. On the other hand, recently accumulating evidence has indicated bidirectional interactions between specific neural activations and local immune responses. Here we discuss one such local neuroimmune interaction, the gateway reflex. The gateway reflex represents a mechanism that translates specific neural stimulations into local inflammatory outcomes by changing the state of specific blood vessels to allow immune cells to extravasate, thus forming the gateway. Several types of gateway reflex have been identified, and each regulates distinct blood vessels to create gateways for immune cells that induce local inflammation. The gateway reflex represents a novel therapeutic strategy for neuroinflammation and is potentially applicable to other inflammatory diseases in peripheral organs.

AB - Numerous studies have focused on the deteriorate role of amyloid-beta (Abeta) on retina, implying the potential pathogenic mechanism underlying age-related macular degeneration (AMD). However, the mechanism underlying the Abeta deposition in AMD patients remains unknown. Beta-site amyloid precursor protein cleaving enzyme 1 (BACE1), rate-limiting enzyme for Abeta production, plays an important role in Abeta deposition in the brain. In the current study, we aimed to clarify the regulation mechanism of BACE1 and explore potential drug targets using a lipofuscinfluorophore A2E-mediated photo-oxidation model. In this model, Abeta1-40 and Abeta1-42 levels increased simultaneously with the enhanced BACE1 expression. These changes were associated with the hypomethylation of specific loci within the BACE1 gene promoter and the decreased levels of DNA methyltransferase 1 (DNMT1). Furthermore, we noticed overlapping regions of differentially methylated CpG islands and specificity protein (Sp1) binding sites within the BACE1 promoter. We employed chromatin immunoprecipitation (ChIP) assay to verify that the decreased BACE1 promoter methylation by DNMT1 enabled increased binding between Sp1 and the BACE1 promoter, which further enhanced BACE1 transcription. The inhibition of Sp1 with mithramycin A (MTM) could down regulate the expression of BACE1 as well as alleviate the RPE barrier morphology and function impairment. Our results for the first time show the competitive regulation of BACE1 by transcription factor Sp1 and DNMT1 after photo-oxidation and confirm the potential novel protective role of MTM on RPE cells.

PMID- 30273644 TI - Subtractive proteomics and immunoinformatics revealed novel B-cell derived T-cell epitopes against Yersinia enterocolitica: An etiological agent of Yersiniosis. AB - Yersinia enterocolitica is the third most common cause of gastrointestinal manifestations in Europe. Statistically, every year the pathogen accounts for 640 hospitalizations, 117,000 illnesses, and 35 deaths in the United States. The associated mortality rate of the pathogen is 50% and is virtually resistant to penicillin G, ampicillin and cephalotin. The development of new and effective therapeutic procedures is urgently needed to counter the multi-drug-resistant phenotypes imposed by the said pathogen. Based on subtractive reverse vaccinology and immunoinformatics approaches, we have successfully predicted novel antigenic peptide vaccine candidates against Y. enterocolitica. The pipeline revealed two isoforms of ompC family; meoA (ompC) and ompC2 as promising vaccine targets. Protein-protein interactions elaborated the involvement of target candidates in the major biological pathways of the pathogen. The predicted 9-mer B-cell derived T-cell epitope of proteins are found to be virulent, antigenic, non-allergic, surface exposed and conserved in all nine completely sequenced strains of the pathogen. Molecular docking predicts deep and stable binding of the epitopes in the binding pocket of the most predominant allele in human population-the DRB1*0101. These epitopes of target proteins could provide the foundation for the development of an epitope-driven vaccine against Y. enterocolitica.

AB - Medical advances in pediatric oncology have led to increases in survival but the long-term adverse effects of treatment in childhood cancer survivors have not yet been examined in depth. In this systematic review, we aimed to study the prevalence and risk factors of late-onset cardiomyopathy (LOCM) among survivors of childhood lymphoma treated with anthracyclines. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines we searched Pubmed/Medline, abstracted data and rated studies on quality regarding late-onset (>1 year following treatment) cardiotoxicity of anthracyclines in survivors of childhood lymphoma. Across 22 identified studies, the prevalence of anthracycline-induced LOCM among survivors of childhood lymphoma ranges from 0 to 40%. Anthracycline dose, administration and dose of mediastinal radiation, patient's age and era of diagnosis and evaluation, follow-up duration as well as disease relapse have been reported as risk factors for LOCM, whereas administration of dexrazoxane seems to act protectively. There was significant between-study heterogeneity with regards to lymphoma subtypes, follow-up duration, definition of outcomes, and anthracycline-based treatment protocols. The rates of anthracycline-induced LOCM among survivors of childhood lymphoma are high and dependent on study design. Future studies should explore whether modifying risk factors and suggested supportive care could decrease its prevalence among childhood lymphoma survivors. Until then, lifelong follow-up of these patients aiming to determinate the earliest signs of cardiac dysfunction is the most important measure towards primordial prevention of LOCM.

PMID- 30273647 TI - The effect of preoperative anemia on patients undergoing cardiac surgery: a propensity-matched analysis. AB - OBJECTIVES: It is unknown if anemia in the absence of transfusions is an independent risk factor for adverse outcomes in cardiac surgery, and if correction to higher hemoglobin targets impacts these outcomes. METHODS: This is a retrospective review of 3,848 cardiac surgery patients. Propensity matching was completed using 41 covariates. Intraoperative Anemia Analysis (IAA) matched patients with or without anemia who did not receive intraoperative transfusions (n=392/group), while Intraoperative Transfusion Analysis (ITA) matched anemic patients treated conventionally with intraoperative transfusions to end CPB hemoglobin greater or less than 95 g/L (n=261/group). Outcomes of death, renal failure, and two composite outcomes were assessed using paired analysis techniques. Study composite 1 consisted of prolonged ventilation, renal failure, MI, stroke, or DSWI, while composite 2 was the TRICS-III composite. RESULTS: In the IAA, anemia was associated with mortality (p=0.034), stroke (p=0.021), renal failure (p=0.015) and a significant increase in the composite measure (control 8.7% vs anemia 16.1%, p=0.002). These findings were unchanged in patients who did not receive any postoperative transfusions. The ITA showed no difference in mortality or the composite outcome between groups. There was a significant increase in low cardiac output in the lower threshold group (p=0.001). There were no differences in outcomes between those who did and did not receive postoperative transfusions (p>0.05). CONCLUSIONS: Preoperative anemia in the absence of transfusions is a risk factor for morbidity and mortality after cardiac surgery, and there is no evidence that transfusion to higher end CPB hemoglobin levels impacted this risk.

AB - Histoplasma capsulatum variety capsulatum (H. capsulatum) is a thermally dimorphic fungus that is endemic to the Mississippi River and Ohio River valley regions. Of the hundreds of thousands of patients exposed to this fungus, less than 1% develop a severe illness most commonly manifesting as pulmonary disease. Septic arthritis from hematogenous seeding with H. capsulatum or from direct inoculation has been reported only rarely in the literature. The first case of septic arthritis of the shoulder due to H. capsulatum occurring in an immunocompromised patient, treated successfully with irrigation and debridement, systemic antifungals, and local delivery of amphotericin B with cement beads, is reported here. Importantly, the addition of local amphotericin B delivery by cement beads to conventional treatment likely led to clinical cure in this patient.

AB - Mutations in ATP6 gene are frequent causes of mitochondrial encephalomyopathies. ATP6 gene encodes one subunit of complexV. The present study described a missense mutation in ATP6 gene in a 8-year-old Chinese boy with mitochondrial encephalomyopathy. We identified one missense mutation in ATP6 gene (m.8914C>T) by mitochondrial DNA sequencing. This mutation altered the amino acid proline in serine, and alterative protein is predicted to be harmful. The mutation load in blood sample of patient is 59.49%. Activity of all mitochondrial complexes in blood are normal, however, the total function of mitochondrial oxidative phosphorylation were declined (including pathwayI, pathwayII and pathwayIV). The missense mutation (m.8914C>T) in ATP6 gene could result in abnormal function of complexV and is related with mitochondrial encephalomyopathy. PMID- 30273651 TI - TAK1 of black carp positively regulates IRF7-mediated antiviral signaling in innate immune activation. AB - Transforming growth factor beta-activated kinase 1 (TAK1) plays a vital role in IL-1-mediated NF-kappaB, JNK, and p38 activation in human and mammals. However, the function of TAK1 in teleost fish still remains largely unknown. To explore the role of TAK1 during the antiviral innate immune response of teleost fish, TAK1 of black carp (Mylopharyngodon piceus) was cloned and characterized in this paper. The open reading frame (ORF) of black carp TAK1 (bcTAK1) consists of 1626 nucleotides and the predicted bcTAK1 protein contains 541 amino acids, which includes a N-terminal Serine/Threonine protein kinases (S/TKc) and a C-terminal coiled-coil region. bcTAK1 migrated around 75 kDa in immunoblotting assay and was identified as a cytosolic protein by immunofluorescence staining. bcTAK1 transcription in Mylopharyngodon piceus kidney (MPK) cells varied in response to the stimulation of poly (I:C), LPS, grass carp reovirus (GCRV), and spring viremia of carp virus (SVCV). bcTAK1 showed deficient IFN-inducing ability in reporter assay and feeble antiviral activity against GCRV and SVCV in plaque assay. However, when co-expressed with bcIRF7 in EPC cells, bcTAK1 obviously enhanced bcIRF7-mediated IFN promoter induction in reporter assay. Accordingly, the data of plaque assay demonstrated that the antiviral activity of bcIRF7 against both GCRV and SVCV was unregulated by bcTAK1. Thus, the data generated in this study support the conclusion that bcTAK1 up-regulates bcIRF7-mediated antiviral signaling during host innate immune activation, which is reported for the first time in vertebrates. PMID- 30273652 TI - Identification and characterization of a B-type mannose-binding lectin from Nile tilapia (Oreochromis niloticus) in response to bacterial infection. AB - Lectins are a group of carbohydrate-binding proteins, which play an important role in innate immune system against pathogen infection. In this study, a B-type mannose-binding lectin (OnBML) was identified from Nile tilapia (Oreochromis niloticus), and characterized at expression patterns against bacterial infection and capability to promote phagocytosis by macrophages. The open reading frame of OnBML is 354 bp of nucleotide sequence encoding polypeptides of 117 amino acids. The deduced protein is highly homologous to other teleost BMLs, containing two repeats of the conserved mannose-binding motif QXDXNXVXY. Expression of OnBML was widely exhibited in all examined tissues, with the most abundance in spleen and following gill, peripheral blood, and head kidney. The OnBML expressions were significantly up-regulated following two major bacterial infections including a Gram-positive bacterium (Streptococcus agalactiae) and a Gram-negative bacterium (Aeromonas hydrophila) in vivo and in vitro. Recombinant OnBML protein possessed capacities of mannose-binding and calcium-dependent agglutination to S. agalactiae and A. hydrophila, and promoted the phagocytosis by macrophages. Taken together, the present study indicated that OnBML is likely to get involved in host defense against bacterial infection in Nile tilapia. PMID- 30273653 TI - Perineuronal nets in brain physiology and disease. AB - Perineuronal nets (PNNs) in the brain are condensed glycosaminoglycan-rich extracellular matrix structures with heterogeneous composition yet specific organization. They typically assemble around a subset of fast-spiking interneurons that are implicated in learning and memory. Owing to their unique structural organization, PNNs have neuroprotective capacities but also participate in signal transduction and in controlling neuronal activity and plasticity. In this review, we define PNN structure in detail and describe its various biochemical and physiological functions. We further discuss the role of PNNs in brain disorders such as schizophrenia, bipolar disorder, Alzheimer disease and addictions. Lastly, we describe therapeutic approaches that target PNNs to alter brain physiology and counter brain dysfunction. PMID- 30273654 TI - Fibroblast growth factor 18 exerts anti-osteoarthritic effects through PI3K-AKT signaling and mitochondrial fusion and fission. AB - Osteoarthritis (OA) is a degenerative disease characterized by progressive loss of cartilage, osteophyte formation and subchondral bone sclerosis. Although some animal experiments have reported that fibroblast growth factor 18 (FGF18) attenuates cartilage degradation, the effect of FGF18 on chondrocytes and its underlying mechanism at the cellular level remain largely unknown. In this study, we found that an intra-articular injection of FGF18 attenuates cartilage degradation, increases Collagen II deposition and suppresses matrix metallopeptidase 13 (MMP13) expression in rat post-traumatic osteoarthritis (PTOA). At the cellular level, FGF18 promotes chondrocyte proliferation through PI3K-AKT signaling and migration through PI3K signaling. We found that FGF18 attenuates IL-1beta-induced apoptosis, restores mitochondrial function and reduces Reactive Oxygen Species (ROS) production through PI3K-AKT signaling. Moreover, the mitochondrial fusion and fission of chondrocytes were enhanced by a short duration of treatment (within 24 h) of IL-1beta and suppressed by prolonged treatment (48 h). FGF18 significantly enhances the mitochondrial fusion and fission, restoring mitochondrial function and morphology, and reduces ROS production. We also found that the FGFR1/FGFR3 ratio, which might contribute to the progression of osteoarthritis, was upregulated by IL-1beta and downregulated by FGF18. To the best of our knowledge, our data demonstrated the anti osteoarthritic effect of FGF18 at the cellular level for the first time and suggested that PI3K-AKT signaling and mitochondrial fusion and fission might play critical roles during the process. Our study proved that FGF18 might be a promising drug for the treatment of early stage osteoarthritis and is worth further study. PMID- 30273655 TI - Metabolism and epigenetics of pancreatic cancer stem cells. AB - Pancreatic Cancer (PDA) is an aggressive malignancy characterized by early spread and a high mortality. Current studies suggest that a subpopulation of cells exist within tumors, cancer stem cell (CSC), which are capable of self-renewal and give rise to unique progeny which form the major neoplastic cellular component of tumors. While CSCs constitute a small cellular subpopulation within the tumor, their resistance to chemotherapy and radiation make them an important therapeutic target for eradication. Along with distinctive phenotypic properties, CSCs possess a unique metabolic plasticity allowing them to rapidly respond and adapt to environmental changes. These cells and their progeny also display a significantly altered epigenetic state with distinctive patterns of DNA methylation. Several mechanisms of cross-talk between epigenetic and metabolic pathways in PDA exist which ultimately contribute to the observed cellular plasticity and enhanced tumorigenesis. In this review we discuss various examples of this metabolic-epigenetic interplay and how it may constitute a new avenue for therapy specifically targeting CSCs in PDA. PMID- 30273656 TI - Parallels between artificial reprogramming and the biogenesis of cancer stem cells: Involvement of lncRNAs. AB - Cellular identity is established and maintained by the interplay of cell type specific transcription factors and epigenetic regulation of the genome. During development in vivo and differentiation in vitro, transitions from one cell type to the next are triggered by cell signaling events culminating in modifications of chromatin that render genes accessible or inaccessible to the transcriptional apparatus. In recent years it has become apparent that cellular identity is plastic, and technological reprogramming methods such as somatic cell nuclear transfer and induced pluripotency can yield reprogrammed cells that have been restored to a state of developmental potency. Long noncoding RNAs (lncRNAs) are untranslated functional RNA molecules that are intimately involved in the regulation of the chromatin of protein-coding genes. In fact, recent evidence shows that there are more lncRNA species in the cell than mRNA species and that most protein-coding genes are likely to be under epigenetic regulation mediated by lncRNAs. This review examines lncRNA function in reprogrammed pluripotent cells and cancer stem cells. Because cancer stem cells arise from normal cells, their biogenesis can be viewed as a reprogramming process that occurs in vivo, and parallels between artificial reprogramming and cancer stem cell biogenesis are discussed. PMID- 30273657 TI - DNP NMR of biomolecular assemblies. AB - Dynamic Nuclear Polarization (DNP) is an effective approach to alleviate the inherently low sensitivity of solid-state NMR (ssNMR) under magic angle spinning (MAS) towards large-sized multi-domain complexes and assemblies. DNP relies on a polarization transfer at cryogenic temperatures from unpaired electrons to adjacent nuclei upon continuous microwave irradiation. This is usually made possible via the addition in the sample of a polarizing agent. The first pioneering experiments on biomolecular assemblies were reported in the early 2000s on bacteriophages and membrane proteins. Since then, DNP has experienced tremendous advances, with the development of extremely efficient polarizing agents or with the introduction of new microwaves sources, suitable for NMR experiments at very high magnetic fields (currently up to 900 MHz). After a brief introduction, several experimental aspects of DNP enhanced NMR spectroscopy applied to biomolecular assemblies are discussed. Recent demonstration experiments of the method on viral capsids, the type III and IV bacterial secretion systems, ribosome and membrane proteins are then described.

PMID- 30273661 TI - Evaluating the clinical importance of bacterial degradation of therapeutic agents in the lower intestine of adults using adult fecal material. AB - PURPOSE: Optimize adult fecal material composition for evaluating the clinical importance of bacterial degradation of therapeutic agents in the lower intestine (distal small intestine, D-SI and proximal colon, P-COL). Evaluate the usefulness of optimized fecal material in the evaluation of bacterial degradation of five model highly permeable drugs: two nitroreductase substrates (nitrendipine and nimodipine), three drugs for which published data indicate no impact of bacterial degradation on in vivo performance (levodopa, budesonide and rivaroxaban) and one prodrug (sulfasalazine, an azoreductase substrate) from which a locally acting on the mucosa of the lower intestine drug is derived (mesalamine). METHODS: 30 min and 95 min were used as point estimates of maximum bacterial degradation half lives for bacterial degradation in D-SI or in P-COL, respectively, to be clinically important, i.e. for at least 20% reduction in absorption from D-SI or P-COL to occur. Optimization of fecal material was based on recently reported degradation profiles of metronidazole (a nitroreductase substrate) and olsalazine (an azoreductase substrate) in the lower intestine of healthy adults which are clinically important. Model compounds were tested in optimized fecal materials and data were evaluated vs. existing in vivo data in adults. RESULTS: Simulated ileal bacteria (SIB) consisted of 5.5% (w/v) stools in normal saline and simulated colonic bacteria (SCoB) consisted of 8.3% (w/v) stools in normal saline. For all model compounds, data in SIB and SCoB were in line with available information in adults. [Degradation half-life in SIB/Degradation half-life in SCoB] ~ [Stool content in SCoB/Stool content in SIB] ~ 1.5, i.e. bacterial degradation in SIB could be predicted from bacterial degradation in SCoB. CONCLUSION: Data in SCoB only are useful for evaluating whether bacterial degradation in P-COL and in D-SI is likely to be clinically important for orally administered, highly permeable drugs or prodrugs which act locally after bacterial degradation. The usefulness of this approach in cases where enzymes other than nitroreductases or azoreductases are involved requires further confirmation. PMID- 30273663 TI - Pluchea lanceolata protects hippocampal neurons from endothelin-1 induced ischemic injury to ameliorate cognitive deficits. AB - Ischemic brain injury is one of the leading causes of death and disability, where lack of disease modifying treatment strategies make us rely on symptomatic relief. Treatment principles from traditional systems of medicine may fill this gap and its validation in modern medicine perspective is important to bring them to mainstream. Here, we evaluated the neuroprotective efficacy of Ayurvedic medicinal herb Pluchea lanceolata in treating ischemic hippocampal injury. Focal hippocampal ischemia was modeled in Wistar rats through stereotaxic intrahippocampal injection of endothelin-1 (ET-1). Post-surgery, hydroalcoholic extract of the rhizome of Pluchea lanceolata (HAPL) was administered orally, once in a day for 14 consecutive days to ischemic rats. There were two treatment groups based on the HAPL dosage; HAPL200 (200 mg/kg body weight) and HAPL400 (400 mg/kg body weight). Comparisons were made with the ET-1 ischemic rats which received only the vehicle, and the normal surgical control. Ischemic hippocampal injury led to severe cognitive deficits as evaluated by Morris water maze and open field test, along with locomotory dysfunction noted in actophotometer test. HAPL treatment significantly attenuated these behavioural deficits in a dose dependent manner. Loss of pyramidal cells and degenerative phenotype of shrunken hyperdensed soma with pyknotic nuclei in CA1 and CA3 hippocampal neurons in ischemia were reversed after HAPL treatment. We provide first evidence for loss of dendritic architecture in ET-1 induced focal ischemic hippocampal injury using Golgi impregnation, where HAPL could salvage the dendritic branching and intersections. Intriguingly, it enhanced the dentritic arborization beyond what is noted in normal rats. Ability of HAPL to reverse oxidative stress, especially through maintaining glutathione peroxidase levels and lipid peroxidation in ischemic condition evidences that it may exert neuroprotection through its antioxidant properties. Thus, Pluchea lanceolata and its constituents provide potential alternative/adjuvant treatment strategy for ischemic hippocampal stroke. PMID- 30273664 TI - Dual role of laminin-511 in regulating melanocyte migration and differentiation. AB - Laminins are the major basement membrane (BM) components and are heterotrimers composed of an alpha, a beta and a gamma chain. In skin, laminins are present in basement membranes surrounding vascular structures, nerves, adipose tissue and in the specialized junctional BM between the epidermis and dermis. The main laminin isoforms in the dermo-epidermal BM are laminin-332, laminin-511 and laminin-211, the latter being restricted to hair follicles (HFs). The laminin gamma1 chain is the most abundant gamma chain; its global ablation in mice leads to early embryonic lethality at E5.5. To elucidate the cellular function of the gamma1 chain in skin, we generated mice with keratinocyte-specific deletion of this chain (Lamc1EKO) by using the keratin (K)14-Cre/loxP system. These mice showed delayed coat pigmentation despite normal melanocyte counts in the skin. However, levels of differentiation-specific melanocyte enzymes TRP-1, TRP-2 and tyrosinase were reduced in Lamc1EKO mice, and melanocytes failed to migrate to their differentiation niche in HFs and accumulated in the IFE. These results suggested that the pigmentation defect results from impaired melanocyte migration. The impaired migratory capacity of melanocytes is due to the altered composition of laminins in the BM of Lamc1EKO mice: Loss of keratinocyte-derived pro-migratory laminin-511 is not compensated by ectopically deposited fibroblast-derived laminin-211. Furthermore, contact of melanocytes with recombinant laminin-511, but not with laminin-211, induces the expression of the chemokine receptor CXCR4 on melanocytes, needed for SDF-1 (stromal cell-derived factor-1)-mediated migration into HFs. We here demonstrate that laminin-511 controls the differentiation of melanocytes by regulating their migration from the epidermis into HFs and by activating CXCR4 expression on melanocytes required for their recruitment into HFs in an SDF-1-dependent manner. PMID- 30273662 TI - The FTO rs9939609 "A" allele is associated with impaired fasting glucose and insulin resistance in Emirati population. AB - BACKGROUND: Fat mass and obesity-associated protein gene variants have shown diverse influence on body weight and metabolism across different populations. Overweight, obesity and metabolic syndrome are multifactorial major health problems in the UAE and worldwide. Insulin resistance represents the link between overweight and development of metabolic syndrome and type 2 diabetes mellitus. We investigated two (FTO) variants in Emirati population, in relation to insulin resistance and different parameters of metabolic syndrome. METHODS: We recruited 259 Emiratis through the UAE National Diabetes and Lifestyle Project. Ethical approval was obtained. Besides basic data collection, venous blood samples were collected. Fasting blood glucose, Lipid profile, and insulin levels were measured. Genotyping for (FTO) rs9939609 (A>T) and rs9930506 (G>A) were performed using real time-PCR. Insulin resistance were identified using HOMA2-IR calculation; with a cut-off point of 1.4 for female and 1.18 for male subjects. RESULTS: The study included 259 Emiratis (age range 30-53 years, mean 41.76 years, 54.4% females), 24.5% are diabetic and 30.8% are hypertensive, with body mass index of 28.4 +/- 5.9 and 28.7 +/- 5.7 kg/m2 in female and male subjects, respectively. Homozygous A of rs9939609 showed significantly higher fasting glucose compared to other genotypes (p = 0.04) with a trend of higher insulin level and HOMA-2IR. The A/A diabetic patients (n = 13) showed significantly higher insulin levels compared to other genotypes. G allele of rs9930506 showed a trend of higher fasting glucose and HOMA-2IR, but lower insulin level and HbA1c. No association of genotypes was detected with other components of metabolic syndrome. CONCLUSION: There is an association of FTO rs9939609 A/A genotype and impaired fasting glucose and insulin resistance. Homozygous A genotype diabetic patients may be more vulnerable to blood glucose fluctuation. Focused genotyping can help the health care providers to identify high risk groups of both normal population and diabetic patients to intervene accordingly. PMID- 30273665 TI - Orodispersible films based on blends of trehalose and pullulan for protein delivery. AB - During the last decades the number of therapeutic proteins increased tremendously on the pharmaceutical market. However, due to their often poor stability and limitations of the administration route, the application of therapeutic proteins is a major challenge. The oral mucosa has been suggested as a possible route for protein delivery. In this study, we prepared protein loaded orodispersible films (ODFs), based on blends of trehalose/pullulan by air- and freeze-drying. These two carbohydrates were selected based on the excellent protein stabilizing capacity of trehalose and film-forming ability of pullulan. ODFs were loaded with three model proteins. Ovalbumin was used to study the effect of protein incorporation on the mechanical properties, disintegration time, uniformity of weight and thickness of the ODFs. Lysozyme and beta-galactosidase were used to evaluate protein stability. Ovalbumin loading did not significantly influence the mechanical properties of freeze-dried ODFs, while incorporation of ovalbumin in air-dried ODFs led to a substantial reduction in tensile strength. The trehalose/pullulan ratio had no impact on the stability of lysozyme, while the stability of beta-galactosidase increased with increasing trehalose/pullulan ratios. Furthermore, freeze-drying appeared to be favorable over air-drying for process stability while the reverse was found for storage stability. In conclusion, trehalose/pullulan-based ODFs are from a technical point promising for possible protein delivery via the oral cavity. PMID- 30273666 TI - Sulfur dioxide attenuates sepsis-induced cardiac dysfunction via inhibition of NLRP3 inflammasome activation in rats. AB - OBJECTIVE: Sulfur dioxide (SO2) plays an important role in maintaining homeostasis of cardiovascular system. This study was aimed to investigate cardioprotective effects of SO2 on in the rat and the underlying mechanism. METHODS AND RESULTS: Sepsis model induced by cecal ligation and puncture (CLP) in rats were used. SO2 donor (NaHSO3/Na2SO3, 1:3 M/M) was administered intraperitoneally at a dose of 85 mg/kg. Primary neonatal rat cardiac ventricular myocytes (NRCMs) were stimulated with LPS (1 mg/mL) in presence or absence of different concentrations of SO2 (10, 50 and 100 MUmol/L). SO2 donor could restore the decreased levels of SO2 in plasma and heart of septic rats. SO2 exhibited dramatic improvement in cardiac functions. At 24 h after CLP, SO2 treatments decreased the number of TUNEL-positive cells, Bax/Bcl-2 ratio and activity of caspase-3. Moreover CLP-induced inflammatory response was also relieved by SO2. In NRCMs, SO2 could suppress the LPS-induced myocardial injury, leading to an increase in cell viability, a decrease in LDH and apoptotic rate. Western blot showed that the expression of TLR4, NLRP3, and Caspase-1 were obviously increased in myocardial tissue of CLP group or in NRCMs of LPS group, while SO2 significantly inhibited the CLP-induced or LPS-induced TLR4, NLRP3, and Caspase-1 expression. CONCLUSION: SO2 attenuated sepsis-induced cardiac dysfunction likely in association with the inhibiting inflammation via TLR4/NLRP3 signaling pathway.

AB - Clostridium difficile is a deadly, opportunistic bacterial pathogen. In the last two decades, C. difficile infections (CDIs) have become a national concern because of the emergence of hypervirulent mutants with increased capability to produce toxins and spores. This has resulted in an increased number of infections and deaths associated with CDI. The scarcity of anticlostridial drugs has led to unsatisfactory cure rates, elevated recurrence rates and permitted enhanced colonization with other drug-resistant pathogens (such as vancomycin-resistant enterococci) in afflicted patients. Therefore, both patients and physicians are facing an urgent need for more effective therapies to treat CDI. In an effort to find new anticlostridial drugs, we investigated auranofin, an FDA-approved oral antirheumatic drug that has recently been found to possess antibacterial activity. Auranofin exhibited potent activity against C. difficile isolates, inhibiting growth at a concentration of 1 ug/mL against 50% of all tested isolates. Auranofin inhibited both toxin production and spore formation, a property lacking in both vancomycin and metronidazole (the primary agents used to treat CDI). Auranofin had a direct protective activity against C. difficile toxin mediated inflammation and inhibited the growth of vancomycin-resistant enterococci. Auranofin is a promising candidate that warrants further investigation as a treatment option for C. difficile infections.

AB - Current knowledge of sand fly salivary components has been based solely on Lutzomyia and Phlebotomus species which feed mainly on mammals; their hyaluronidases and apyrases were demonstrated to significantly affect blood meal intake and transmission of vector-borne pathogens. Members of the third sand fly genus Sergentomyia preferentially feed on reptiles but some of them are considered as Leishmania and arboviruses vectors; however, nothing is known about their salivary components that might be relevant for pathogens transmission. Here, marked hyaluronidase and apyrase activities were demonstrated in the saliva of a Sergentomyia schwetzi colony maintained on geckos. Hyaluronidase of S. schwetzi cleaved hyaluronan as the prominent substrate, and was active over a broad pH range from 4.0 to 8.0, with a sharp peak at pH 5.0. SDS PAGE zymography demonstrated the monomeric character of the enzyme, which remained active in reducing conditions. The apparent molecular weight of 43 kDa was substantially lower than in any sand fly species tested so far and may indicate relatively low grade of the glycosylation of the enzyme. The apyrase of S. schwetzi was typical strictly Ca2+ dependent Cimex-family apyrase. It was active over a pH range from 6.5 to 9.0, with a peak of activity at pH 8.5, and had an ATPase/ADPase ratio of 0.9. The apyrase activity increased during the first 3 days post-emergence, then reached a plateau and remained relatively constant until day 8. In comparison with a majority of Phlebotomus and Lutzomyia species tested to date, both the hyaluronidase and apyrase activities of S. schwetzi were relatively low, which may reflect an adaptation of this sand fly to blood feeding on non-mammalian hosts. PMID- 30273669 TI - Chemical chaperone-conjugated exendin-4 as a cytoprotective agent for pancreatic beta-cells. AB - Endoplasmic reticulum stress has been considered a major cause of pancreatic beta cell dysfunction and apoptosis leading to diabetes. Glucagon-like peptide-1 receptor activation and chemical chaperones have been known to reduce endoplasmic reticulum stress and improve beta-cell function and survival. The purpose of this study was to prepare and evaluate the chemical chaperone tauroursodeoxycholic acid-conjugated exendin-4 as a protective agent for pancreatic beta-cells. Mono tauroursodeoxycholic acid-Lys27-exendin-4 conjugate (TUM1-Ex4) showed better receptor binding affinity than other conjugates with strong in vitro insulinotropic activity in rat pancreatic beta-cells and in vivo hypoglycemic activity in type 2 diabetic db/db mice. In INS-1 cells under endoplasmic reticulum stress induced by thapsigargin, TUM1-Ex4 promoted cell survival in a dose-dependent manner. In western blot analysis, TUM1-Ex4 reduced the expression of the endoplasmic reticulum stress marker GRP78 and phosphorylation of the translation initiation factor eIF2alpha. These results reveal that TUM1-Ex4 accelerates translational recovery and contributes to beta-cell protection and survival. The present study indicates that the chemical chaperone-coupled glucagon-like peptide-1 receptor agonist is a feasible therapeutic strategy to enhance beta-cell function and survival. PMID- 30273671 TI - Co-infection of Clostridioides (Clostridium) difficile GMU1 and Bacillus cereus GMU2 in one patient in Guizhou, China. AB - Clostridioides (Clostridium) difficile and Bacillus cereus infections are frequently reported in human individually. However, co-infection of both pathogens in human is extremely rare. In the present study, we reported a case of human enteric disease caused by co-infection of C. difficile and B. cereus in Guizhou, China. The 16S rDNA sequencing result showed that C. difficile GMU1 and B. cereus GMU2 were most related to C. difficile ATCC 9689 and B. cereus ATCC 14579. The toxin genotype of C. difficile GMU1 and B. cereus GMU2 were tcdA+tcdB+tcdC+ and bceT+nheA+nheB+nheC+, respectively. Cytotoxicity assay demonstrated that C. difficile GMU1 produced significantly higher toxin B compare to C. difficile 630 stain. In contrast, B. cereus GMU2 has comparable NheA toxin productivity compare to previous report. The antimicrobial susceptibility test showed that the combination of ampicillin and vancomycin was most efficient to inhibit both C. difficile GMU1 and B. cereus GMU2. PMID- 30273672 TI - Cathelicidin-WA attenuates LPS-induced inflammation and redox imbalance through activation of AMPK signaling. AB - Dysregulated activation of inflammation is associated with the development and progression of many diseases. Generation of reactive oxygen species (ROS) has been shown to promote an inflammatory response. Cathelicidin peptides not only defend against the invasion of various microbes but also play an important role in regulating immune responses. The objective of this study was to investigate the effects and mechanisms of Cathelicidin-WA (CWA) on the inflammatory response and oxidative stress in macrophages. Our results showed that CWA efficiently attenuated lipopolysaccharide (LPS)-stimulated inflammation and oxidative stress both in vivo and in vitro. Mechanistically, we found that CWA significantly reduced the LPS-induced nuclear translocation of NF-kappaB, thus decreasing the production of the pro-inflammatory cytokines TNF-alpha and IL-6 in macrophages. On the other hand, CWA markedly promoted the nuclear translocation of Nrf2 via the AKT pathway and p38 signaling. This resulted in increased expression of the anti-oxidative genes NQO-1 and HO-1 and alleviated oxidative stress in LPS stimulated macrophages. Interestingly, the effects of CWA were diminished when AMPK was knocked down. Consistently, we noticed that CWA failed to ameliorate the LPS-induced inflammatory response and oxidative stress in AMPK knockout mice. Furthermore, we discovered that LKB1 was essential for AMPK activation by CWA. These data demonstrated for the first time that CWA attenuated LPS-stimulated inflammation and redox imbalance through regulating LKB1-AMPK signaling. Such knowledge provides new insights into the mechanisms through which Cathelicidin peptides modulate immune responses. PMID- 30273673 TI - Ask the Authors. PMID- 30273674 TI - Ask the Authors. PMID- 30273675 TI - Optimal human iPS cell culture method for efficient hepatic differentiation. AB - Hepatocyte-like cells differentiated from human iPS cells are expected to be utilized in pharmaceutical research and regenerative medicine. Recently, various culture methods for human iPS cell maintenance have been developed. However, it is not well known whether human iPS cell maintenance method affects hepatic differentiation potency. In this study, we cultured human iPS cells using four maintenance methods: ReproStem medium with feeder cells (mouse embryonic fibroblasts), AK02N medium with iMatrix-511 (E8 fragments of laminin511), Essential 8 medium with Vitronectin N (N-terminal domain of vitronectin), TeSR-E8 medium with Vitronectin XF (xeno-free vitronectin). Then, these human iPS cells were differentiated into the hepatocyte-like cells. Interestingly, the gene expression levels of definitive endoderm markers in the definitive endoderm cells generated from human iPS cells cultured with ReproStem or TeSR-E8 medium were higher than those in other groups. The gene expression level of foregut marker, HHEX, in the definitive endoderm cells generated from human iPS cells cultured with ReproStem medium was higher than that in other groups. Consistently, the expression levels of hepatocyte markers, albumin and urea secretion capacity, and CYP3A4 activity in the hepatocyte-like cells generated from human iPS cells cultured with ReproStem medium were higher than those in the other groups. Our data indicated that the most suitable human iPS cell maintenance method for efficient hepatic differentiation was the on-feeder method which uses mouse embryonic fibroblasts, but not feeder-free methods. In conclusion, human iPS cell maintenance method largely affects hepatic differentiation potency. PMID- 30273676 TI - Significance of urinary 11-dehydro-thromboxane B2 in age-related diseases: Focus on atherothrombosis. AB - Platelet activation plays a key role in atherogenesis and atherothrombosis. Biochemical evidence of increased platelet activation in vivo can be reliably obtained through non-invasive measurement of thromboxane metabolite (TXM) excretion. Persistent biosynthesis of TXA2 has been associated with several ageing-related diseases, including acute and chronic cardio-cerebrovascular diseases and cardiovascular risk factors, such as cigarette smoking, type 1 and type 2 diabetes mellitus, obesity, hypercholesterolemia, hyperhomocysteinemia, hypertension, chronic kidney disease, chronic inflammatory diseases. Given the systemic nature of TX excretion, involving predominantly platelet but also extraplatelet sources, urinary TXM may reflect either platelet cyclooxygenase-1 (COX-1)-dependent TX generation or COX-2-dependent biosynthesis by inflammatory cells and/or platelets, or a combination of the two, especially in clinical settings characterized by low-grade inflammation or enhanced platelet turnover. Although urinary 11-dehydro-TXB2 levels are largely suppressed with low-dose aspirin, incomplete TXM suppression by aspirin predicts the future risk of vascular events and death in high-risk patients and may identify individuals who might benefit from treatments that more effectively block in vivo TX production or activity. Several disease-modifying agents, including lifestyle intervention, antidiabetic drugs and antiplatelet agents besides aspirin have been shown to reduce TX biosynthesis. Taken together, these aspects may contribute to the development of promising mechanism-based therapeutic strategies to reduce the progression of atherothrombosis. We intended to critically review current knowledge on both the pathophysiological significance of urinary TXM excretion in clinical settings related to ageing and atherothrombosis, as well as its prognostic value as a biomarker of vascular events. PMID- 30273677 TI - Exploring the Diagnosis and Profile of Cannabis Allergy. AB - BACKGROUND: Cannabis allergy (CA) has mainly been attributed to Can s 3, the nonspecific lipid transfer protein (nsLTP) of Cannabis sativa. Nevertheless, standardized diagnostic tests are lacking and research on CA is scarce. OBJECTIVE: To explore the performance of 5 cannabis diagnostic tests and the phenotypic profile of CA. METHODS: A total of 120 patients with CA were included and stratified according to the nature of their cannabis-related symptoms; 62 healthy and 189 atopic controls were included. Specific IgE (sIgE) hemp, sIgE and basophil activation test (BAT) with a recombinant Can s 3 protein from Cannabis sativa (rCan s 3), BAT with a crude cannabis extract, and a skin prick test (SPT) with an nCan s 3-rich cannabis extract were performed. Clinical information was based on patient history and a standardized questionnaire. RESULTS: First, up to 72% of CA reporting likely-anaphylaxis (CA-A) are Can s 3 sensitized. Actually, the Can s 3-based diagnostic tests show the best combination of positive and negative predictive values, 80% and 60%, respectively. sIgE hemp displays 82% sensitivity but only 32% specificity. Secondly, Can s 3+CA reported significantly more cofactor-mediated reactions and displayed significantly more sensitizations to other nsLTPs than Can s 3-CA. Finally, the highest prevalence of systemic reactions to plant-derived foods was seen in CA-A, namely 72%. CONCLUSIONS: The most effective and practical tests to confirm CA are the SPT with an nCan s 3 rich extract and the sIgE rCan s 3. Can s 3 sensitization entails a risk of systemic reactions to plant-derived foods and cofactor-mediated reactions. However, as Can s 3 sensitization is not absolute, other cannabis allergens probably play a role. PMID- 30273678 TI - Performance of MRI for the detection of anterior pelvic endometriotic lesions. AB - OBJECTIVE: To study the performance of MRI for the detection of anterior pelvic endometriotic lesions. MATERIALS AND METHODS: We carried out a retrospective, single site, case-controlled study of patients who underwent surgery for endometriosis between March 2005 and December 2013. Laparoscopy was used to obtain the reference diagnosis of the endometriotic lesions. We age-matched patients with anterior endometriosis with those with isolated posterior endometriosis for reference. All of the pre-therapeutic MRI data were anonymized and blindly reread by two radiologists (junior and senior) twice. They assessed the overall presence of anterior lesions, those of the inter-vesicouterine space, the detrusor, the uterus, and posterior lesions. For each site, we calculated the sensitivity (Se) and specificity (Sp) for each reading compared to the reference, as well as the inter- and intra-operator variability using the Kappa coefficient (K) with its 95% confidence interval (95% CI). RESULTS: During the study period, 256 patients underwent surgery for endometriosis: 22 presented with anterior endometriosis at surgery, and had had pre-preoperative imagery. We included 22 controls who had an isolated posterior lesion. For the overall detection of anterior lesions, the two radiologists had an identical Se of 77.3% (95% CI; 54.6 92.2). The Sp was 100% (95% CI; 82.4-100) for the junior, and 89.5% (95% CI; 66.9 98.7) for the senior radiologist. The area under the ROC curve was 0.89 (95% CI; 0.80-0.98) for the junior and 0.81 (95% CI; 0.68-0.93) for the senior radiologist. The intra-operator variability was low with almost perfect reproducibility for the overall detection of anterior lesions; k=0.90 (95% CI; 0.77-1) for the junior and k=0.85 (95% CI; 0.70-1) for the senior radiologist. For the various anterior sites, the junior radiologist had k values between 0.60 and 1, whereas those of the senior radiologist were between 0.87 and 1. For inter operator reproducibility, there was modest agreement between the two radiologists, k=0.46 (95% CI; 0.19-0.73), for the overall detection of anterior lesions; k varied between 0.43 and 0.61, depending on the site. CONCLUSION: Our results show that the characterization of anterior lesions by MRI is specific, but not very sensitive, with only moderate inter-operator reproducibility depending on the site. MRI can be used to diagnose anterior lesions, but cannot replace laparoscopy. PMID- 30273679 TI - GM1 locates to mature amyloid structures implicating a prominent role for glycolipid-protein interactions in Alzheimer pathology. AB - While the molecular mechanisms underlying Alzheimer's disease (AD) remain largely unknown, abnormal accumulation and deposition of beta amyloid (Abeta) peptides into plaques has been proposed as a critical pathological process driving disease progression. Over the last years, neuronal lipid species have been implicated in biological mechanisms underlying amyloid plaque pathology. While these processes comprise genetic features along with lipid signaling as well as direct chemical interaction of lipid species with Abeta mono- and oligomers, more efforts are needed to spatially delineate the exact lipid-Abeta plaque interactions in the brain. Chemical imaging using mass spectrometry (MS) allows to probe the spatial distribution of lipids and peptides in complex biological tissues comprehensively and at high molecular specificity. As different imaging mass spectrometry (IMS) modalities provide comprehensive molecular and spatial information, we here describe a multimodal ToF-SIMS- and MALDI-based IMS strategy for probing lipid and Abeta peptide changes in a transgenic mouse model of AD (tgAPPArcSwe). Both techniques identified a general AD-associated depletion of cortical sulfatides, while multimodal MALDI IMS revealed plaque specific lipid as well as Abeta peptide isoforms. In addition, MALDI IMS analysis revealed chemical features associated with morphological heterogeneity of individual Abeta deposits. Here, an altered GM1 to GM2/GM3 ganglioside metabolism was observed in the diffuse periphery of plaques but not in the core region. This was accompanied by an enrichment of Abeta1-40arc peptide at the core of these deposits. Finally, a localization of arachidonic acid (AA) conjugated phosphatidylinositols (PI) and their corresponding degradation product, lyso-phosphatidylinositols (LPI) to the periphery of Abeta plaques was observed, indicating site specific macrophage activation and ganglioside processing. PMID- 30273680 TI - Risk factors of pelvic pressure ulcer recurrence after primary skin flap surgery in people with spinal cord injury. AB - BACKGROUND: Flap surgery for deep pelvic pressure ulcers (PPUs) has been found effective, but the recurrence rate remains high and few risk factors have been identified. OBJECTIVE: We evaluated risk factors for PU recurrence after primary flap surgery in people with spinal cord injury (SCI). PATIENTS AND METHODS: This observational retrospective study based on medical charts included all individuals with SCI who underwent primary flap surgery for a PPU in the Herault department in France between 2006 and 2014. Overall, 100 biomedical, psychological, socioeconomic and care management factors were studied. The primary outcome was PPU recurrence (surgical site and/or other pelvic site). The secondary outcome was recurrence at the surgical site. Cox proportional hazards regression was used to determine associated factors, estimating hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: We included 85 patients. Half had a PPU recurrence, and in one-third, the recurrence was at the surgical site. On multivariate analysis, global PPU recurrence was associated with colostomy (HR=2.79) and living with a partner (HR=2.29). Non-traumatic SCI and sacral wound were associated with PPU recurrence (HR=3.39, HR=0.48) and recurrence at the surgical site (HR=3.3, HR=0.3). CONCLUSION: Risk factors of PPU recurrence are based on both biomedical and social models. After primary flap surgery, the risk of recurrence justifies regular follow-up and strict monitoring.

PMID- 30273684 TI - Kinesio taping improves pain and function in patients with knee osteoarthritis: A meta-analysis of randomized controlled trials. AB - OBJECTIVE: To perform a meta-analysis from randomized controlled trials (RCTs) to evaluate the efficacy of Kinesio Taping in reducing pain and increasing knee function in patients with knee osteoarthritis (OA). METHODS: The electronic databases include PubMed, Embase, web of science and the Cochrane Library up to August 2018. Studies searched were considered eligible if they met the criteria as follows: Population: patients with knee OA; Intervention: intervention groups received Kinesio Taping for the treatment of knee OA; Comparisons: Control group received sham taping; 3) Outcomes: visual analog scale (VAS), McMaster Universities Arthritis Index (WOMAC) scale, range of motion and muscle strength; Study design: RCTs. The Cochrane Collaboration's tool was used to assess risk of bias. We assessed statistical heterogeneity for each RCT with the use of a standard Chi2 test and the I2 statistic. STATA statistical software 15.0 was used for meta-analysis. RESULTS: Five RCTs involving 308 patients were included. The present meta-analysis demonstrated that there were significant differences between Kinesio Taping groups and control groups in terms of visual analog scale (VAS), WOMAC scale and flexion range of motion. No significant difference was found regarding quadriceps femoris muscle between groups. CONCLUSION: Kinesio Taping is effective in improving for pain and joint function in patients with knee OA. Due to the limited quality of the evidence currently available, the results of our meta-analysis should be treated with caution. PMID- 30273683 TI - Neutrophil Gelatinase-Associated Lipocalin (NGAL) in predicting acute kidney injury following orthotopic liver transplantation: A systematic review. AB - BACKGROUND: Acute kidney injury (AKI) is common after orthotopic liver transplantation (OLT) usually occurring early post-transplant. Multiple causes include graft preservation injury, blood loss, hypotension but also severity of recipient liver disease. Early intervention in AKI has both short and long term patient benefits. Unfortunately there are no current clinical biomarkers of early AKI. AIM: To assess the value of NGAL in predicting AKI following OLT. METHODS: Ovid MEDLINE and EMBASE were searched between the years of 2000 and 2017 for studies using keywords: Neutrophil Gelatinase Associated Lipocalin or NGAL variants combined with synonyms for liver transplantation. RESULTS: 96 studies were identified. 11 studies including 563 patients were considered suitable for analysis. Both urinary (uNGAL) and plasma NGAL (pNGAL) measurement were found to predict AKI after liver transplantation. Optimal reported area under the receiver operator characteristics curve (AUROC) values of 0.5-0.83 and 0.54-0.86 respectively. CONCLUSIONS: NGAL is a good predictor of early AKI post OLT although there is considerable variation in the published results. Further studies with prospectively defined cut-off values, standardized definitions of AKI and rigorous data reporting should be conducted to establish its clinical usefulness and limitations. PMID- 30273682 TI - Exploring sialyl-Tn expression in microfluidic-isolated circulating tumour cells: A novel biomarker and an analytical tool for precision oncology applications. AB - Circulating tumour cells (CTCs) originating from a primary tumour, lymph nodes and distant metastases hold great potential for liquid biopsies by providing a molecular fingerprint for disease dissemination and its temporal evolution through the course of disease management. CTC enumeration, classically defined on the basis of surface expression of Epithelial Cell Adhesion Molecule (EpCAM) and absence of the pan-leukocyte marker CD45, has been shown to correlate with clinical outcome. However, existing approaches introduce bias into the subsets of captured CTCs, which may exclude biologically and clinically relevant subpopulations. Here we explore the overexpression of the membrane protein O glycan sialyl-Tn (STn) antigen in advanced bladder and colorectal tumours, but not in blood cells, to propose a novel CTC isolation technology. Using a size based microfluidic device, we show that the majority (>90%) of CTCs isolated from the blood of patients with metastatic bladder and colorectal cancers express the STn antigen, supporting a link with metastasis. STn+ CTC counts were significantly higher than EpCAM-based detection in colorectal cancer, providing a more efficient cell-surface biomarker for CTC isolation. Exploring this concept, we constructed a glycan affinity-based microfluidic device for selective isolation of STn+ CTCs and propose an enzyme-based strategy for the recovery of viable cancer cells for downstream investigations. Finally, clinically relevant cancer biomarkers (transcripts and mutations) in bladder and colorectal tumours, were identified in cells isolated by microfluidics, confirming their malignant origin and highlighting the potential of this technology in the context of precision oncology. PMID- 30273685 TI - Higher Prevalence of Endometrial Polyps in Patients with Fallopian Tube Obstruction: A Case-Control Study. AB - STUDY OBJECTIVE: To study the association between endometrial polyps and fallopian tube patency diagnosed by hysteroscopy, conventional histology, and four-dimensional hysterosalpingo contrast sonography (4D-HyCoSy). DESIGN: Case control study (Canadian Task Force classification II-2). SETTING: University hospital. PATIENTS: A total of 323 women of reproductive age underwent 4D-HyCoSy and hysteroscopy between January 2015 and December 2017. INTERVENTION: A retrospective analysis of the association of endometrial polyps and fallopian tube obstruction (n = 154) or patency (n = 169) in patients who underwent 4D HyCoSy. MEASUREMENTS AND MAIN RESULTS: The prevalence of endometrial polyps was significantly higher in patients with bilateral fallopian tube obstruction than in patients with bilateral fallopian tube patency (42.9% [66 of 154] vs 20.1% [34 of 169]; p < .0001). In univariate and multivariate analyses, the presence of endometrial polyps was found to be a risk factor for tubal obstruction with an odds ratio of 3.16 and 2.59, respectively. CONCLUSION: The prevalence of endometrial polyps is higher in infertile patients with fallopian tube obstruction than in patients with fallopian tube patency. History of endometrial polyps, ectopic pregnancy, and pelvic inflammatory disease are risk factors for tubal obstruction. PMID- 30273686 TI - The Association of Sonographic Evidence of Adenomyosis with Severe Endometriosis and Gene Expression in Eutopic Endometrium. AB - STUDY OBJECTIVE: To examine the presence of sonographic evidence of adenomyosis (SEOA) in patients undergoing laparoscopic surgery for the investigation of endometriosis and to assess if there is an association between SEOA and endometriosis severity. Using gene expression analysis, we also aimed to determine if gene expression in eutopic endometria differed in patients with and without adenomyosis. DESIGN: A prospective study (Canadian Task Force classification II-2). SETTING: A tertiary medical center. PATIENTS: Reproductive age women who underwent laparoscopic surgery after presenting to a pelvic pain focused gynecology clinic. INTERVENTIONS: Endometrial tissue, detailed patient questionnaires, pathology, and surgical notes were collected. Sonographic data from tertiary ultrasounds performed up to 12 months before surgery were retrospectively added (n = 234, researchers blinded to surgical and pathological findings). Gene array data from endometrial biopsies (n = 41) were used to analyze differential gene expression; patients were divided into 2 groups according to the presence or absence of SEOA. MEASUREMENTS AND MAIN RESULTS: Of the 588 patients recruited, 234 (40%) had an available pelvic scan and were included in this study. The average age of the included women was 30.6 years, with 35% having SEOA. Patients with SEOA were 5.4 years older (p = .02). There was no significant difference in the rates of endometriosis between groups; however, patients with SEOA were more likely to have stage IV endometriosis (41% vs 9.8%, p <.001). Patients with SEOA were also more likely to have other markers of severe endometriosis such as endometriomas and deep infiltrating endometriosis (p <.001). No significant difference was observed in endometrial gene expression between adenomyosis cases and controls after adjusting for menstrual c'ycle phases and the presence/absence of endometriosis. CONCLUSION: Sonographic features of adenomyosis may be included as a component of the clinical assessment when attempting to predict the presence of severe endometriosis. No differences in gene expression were observed. Further research is needed to characterize uterine adenomyosis and to explore molecular pathways involved in its pathogenesis. PMID- 30273687 TI - Determining Pain Catastrophizing From Daily Pain App Assessment Data: Role of Computer-Based Classification. AB - This study compared persons with chronic pain who consistently reported that their pain was worsening with those who reported that their pain was improving or remaining the same per daily assessment data from a smartphone pain app. All participants completed baseline measures and were asked to record their progress every day by answering whether their overall condition had improved, remained the same, or gotten worse (perceived change) on a visual analogue scale. One hundred forty-four individuals with chronic pain who successfully entered daily assessments were included. Those persons who were classified as worse showed significantly higher pain intensity scores, greater activity interference, higher disability and mood disturbance scores, and higher scores on the Pain Catastrophizing Scale both at baseline and after 3 months (P < .001). Repeated measures analyses and multilevel modeling of perceived change data over different time intervals of 20 assessments over 40 days, 10 assessments over 20 days, and 5 assessments over 10 days were examined. These analyses demonstrated that group classification of better, same, and worse could be reliably determined, even with as few as 5 assessments. These results support the use of innovative mobile health technology to identify individuals who are prone to catastrophize about their pain. Perspective: This study demonstrated that daily assessment of overall perceived change with a smartphone pain app was positively correlated with the Pain Catastrophizing Scale and capturing short-term daily assessment trends data using computer-based classification methods might be a future way to help to identify individuals who tend to catastrophize about their pain. PMID- 30273688 TI - Self-Medication With Over-the-Counter Analgesics: A Survey of Patient Characteristics and Concerns About Pain Medication. AB - Pain is a common reason for self-medication with over-the-counter (OTC) analgesics. However, this self-treating population has remained largely uncharacterized. This cross-sectional observational study investigated individuals who self-medicate their pain with OTC analgesics to elucidate their pain characteristics and medication use. In addition, presence of and risk factors for concerns about pain medication were examined. The clinical profile of the participants (n = 1,889) was worse than expected with long-standing pain complaints (median pain duration of 9 years), pain located at multiple body sites (median of 4, and 13% with >=10 painful body areas), about one-third suffering from daily pain and about 40% experiencing substantial pain-related disability. Head (58.6% of sample), low back (43.6%), and neck (30.7%) were the most common pain locations. About 73% had a physician diagnosis, mainly migraine and osteoarthritis. Paracetamol (used by 68.6% of patients) and nonsteroidal anti inflammatory drugs (46.8%) were the most frequently used pain medications. About 40% of our sample showed substantial concern about the perceived need for pain medication and the perceived potential for harmful effects (eg, fear for addiction). These findings highlight the importance for health professionals to systematically probe pain patients about their self-medication practices and explore attitudes about pain medication. Perspective: This study found that the clinical picture of people who self-medicate their pain with OTC analgesics looked worse than expected. We also identified substantial concerns about pain medication. Therefore, we recommend that health professionals systematically probe pain patients about their self-medication practices and explore concerns about pain medication. PMID- 30273689 TI - Child Abuse and Neglect Risk Assessment: Quality Improvement in a Primary Care Setting. AB - OBJECTIVES: Practicing SafetyTM (PS) is an AAP toolkit to help practices address child abuse and neglect (CAN) risk by increasing screening and providing resources. The objectives, in an urban practice serving low-income children, were to 1) standardize CAN risk assessment and developmental screening and 2) improve resource provision. METHODS: A quality improvement (QI) initiative to standardize CAN risk assessment, using materials adapted from PS (aPS) was conducted through the use of "SmartTools" in an electronic health record (EHR). The Edinburgh Postnatal Depression Scale and Parents Evaluation of Developmental Status were used to assess maternal depression and child development, respectively. Charts were reviewed in waves: pre-, immediate post-, and early post-implementation (waves 1-3), monthly for six months (waves 4-9), then quarterly for 12 months (waves 10-13) to assess screening and resource provision for six domains: infant crying, maternal depression, development, discipline, temper tantrums, and toilet training. RESULTS: A total of 581 charts were reviewed (waves 1-3: 92, 95, 94, respectively; waves 4-13: 30 each). Screening for infant crying, maternal depression, development, and discipline rose from 0% pre- to over 50% post implementation. Screening for temper tantrums and toilet training rose from 6% to 72% and 36% to 82%, respectively. For all measures, resource provision improved over time, and all improvements were maintained for 1.5 years post implementation. CONCLUSIONS: Incorporating aPS into an EHR is a practical and effective approach to improving CAN risk assessment and resource provision. This QI initiative is an example of a practice-wide improvement that resulted in clinical practice change. PMID- 30273690 TI - Creation and validation of tool to assess resident competence in neonatal resuscitation. AB - BACKGROUND: The American Board of Pediatrics requires that pediatricians be able to initiate stabilization of a newborn. After residency, 45% of general pediatricians routinely attend deliveries. However, there is no standard approach or tool to measure resident proficiency in newborn resuscitation across training programs. In a national survey, we found a large variability in faculty assessment of the amount of supervision trainees need for various resuscitation scenarios. Objective documentation of trainee performance would permit competency based decisions on the level of supervision required and facilitate feedback on trainee performance. METHODS: A simplified tool was created following the Neonatal Resuscitation Program (NRP) algorithm, with emphasis on communication, leadership, knowledge of equipment, and initial stabilization. To achieve content validity, the tool was evaluated by the NRP steering committee. To assess internal structure of the tool, we filmed 10 simulated resuscitation scenarios 9 of which contained errors. Experienced resuscitation team members used the tool to assess performance of the team leader in the videos. To evaluate the response process, the tool was used to assess experienced resuscitators in real time at academic and non-academic sites. RESULTS: The NRP steering committee approved the tool, providing evidence of content validity. Performance of the team leader in the simulated videos was assessed by 16 evaluators using the tool. There was an intra-class coefficient of 0.86 showing excellent agreement. There was no statistical difference in scores between 102 resuscitations led by experienced resuscitators at academic and non-academic hospitals (p=0.98), which demonstrates generalizability. CONCLUSIONS: The tool we have developed to assess performance in initiating newborn resuscitation shows evidence of construct validity based on assessment of content and internal structure (inter-observer agreement, response processes, and generalizability). PMID- 30273691 TI - Carbon monoxide releasing molecule A-1 attenuates acetaminophen-mediated hepatotoxicity and improves survival of mice by induction of Nrf2 and related genes. AB - Acute liver injury is frequently associated with oxidative stress. Here, we investigated the therapeutic potential of carbon monoxide releasing molecule A-1 (CORM A-1) in oxidative stress-mediated liver injury. Overnight-fasted mice were injected with acetaminophen (APAP; 300 mg/kg; intraperitoneally) and were sacrificed at 4 and 12 h. They showed elevated levels of serum transaminases, depleted hepatic glutathione (GSH) and hepatocyte necrosis. Mice injected with CORM A-1 (20 mg/kg) 1 h after APAP administration, had reduced serum transaminases, preserved hepatic GSH and reduced hepatocyte necrosis. Mice that received a lethal dose of APAP (600 mg/kg), died by 10 h; but those co-treated with CORM A-1 showed a 50% survival. Compared to APAP-treated mice, livers from those co-treated with CORM A-1, had upregulation of Nrf2 and ARE genes (HO-1, GCLM and NQO-1). APAP-treated mice had elevated hepatic mRNA levels of inflammatory genes (Nf-kappaB, TNF-alpha, IL1-beta and IL-6), an effect blunted in those co-treated with CORM A-1. In tert-butyl hydroperoxide (t-BHP)-treated HepG2 cells, CORM A-1 augmented cell viability, reduced oxidative stress, activated the nuclear factor erythroid 2-related factor 2 (Nrf2) and anti-oxidant response element (ARE) genes. The molecular docking profile of CO in the kelch domain of Keap1 protein suggested that CO released from CORM A-1 mediated Nrf2 activation. Collectively, these data indicate that CORM A-1 reduces oxidative stress by upregulating Nrf2 and related genes, and restoring hepatic GSH, to reduce hepatocyte necrosis and thus minimize liver injury that contributes to an overall improved survival rate.

AB - OBJECTIVE: To compare serum resistin concentrations between prepubertal girls with a BMI > 85th percentile and girls with precocious puberty (CPP) who have and have not undergone GnRH analog treatment. PATIENTS AND METHODS: This is a cross sectional study in girls with a BMI > 85th percentile and a median age of 8 years. We included 31 girls with CPP who did not receive treatment (CPPoT), 23 girls with CPP who were treated with leuprolide (CPPT), 22 prepubertal girls and 24 pubertal girls. Anthropometric data and the fasting plasma concentrations of lipids, glucose, insulin, and resistin were measured. RESULTS: The z-BMI scores were similar among the groups (p = 0.344), and body fat percentage (BF%) was similar among CPPT, CPPoT and prepubertal girls (p = 0.151). Resistin and insulin levels were lower in girls with CPP (CPPT and CPPoT) than in prepubertal and pubertal girls (median resistin level: CPPT 11.8 pg/ml vs CPPoT 11 pg/ml vs prepubertal 16 pg/ml vs pubertal 16 pg/ml, p = 0.001; median insulin level: CPPT 10.7 MUUI/mL vs CPPoT 10.2 MUUI/mL vs prepubertal 14.4 MUUI/mL vs pubertal 32 MUUI/mL p = 0.02). ANCOVA analysis, after adjustments for pubertal stage, BF% and z-BMI, showed that CPP modifies resistin levels (F = 31.4; p = 0.0001) independently of these parameters (p < 0.05). CONCLUSIONS: In the group of girls with overweight or obesity, the resistin level was lower in girls with CPP than in prepubertal and pubertal girls. More studies are needed to understand the role of resistin in CPP patients. PMID- 30273693 TI - PAC1 regulates receptor tyrosine kinase transactivation in a reactive oxygen species-dependent manner. AB - Pituitary adenylate cyclase activating polypeptide (PACAP) is a growth factor for lung cancer cells. PACAP-27 or PACAP-38 binds with high affinity to non-small cell lung cancer (NSCLC) cells, causing elevated cytosolic Ca2+, increased proliferation and increased phosphorylation of extracellular regulated kinase (ERK) and the epidermal growth factor receptor (EGFR). The role of reactive oxygen species (ROS) was investigated in these processes. Addition of PACAP-38 to NCI-H838 or A549 cells increased the tyrosine phosphorylation of the EGFR, HER2 and ERK significantly by 4-, 3-, and 2-fold, respectively. The transactivation of the EGFR and HER2 was inhibited by gefitinib or lapatinib (tyrosine kinase inhibitors), PACAP (6-38) (PAC1 antagonist), N-acetylcysteine (NAC is an anti oxidant) or dipheyleneiodonium (DPI is an inhibitor of Nox and Duox enzymes). PACAP-38 addition to NSCLC cells increased ROS which was inhibited by PACAP (6 38), NAC or DPI. Nox1, Nox2, Nox3, Nox4, Nox5, Duox1 and Duox2 mRNA was present in many NSCLC cell lines. PACAP-38 stimulated the growth of NSCLC cells whereas PACAP (6-38), gefitinib or DPI inhibited proliferation. The results show that ROS are essential for PAC1 to regulate EGFR and HER2 transactivation as well as proliferation of NSCLC cells.

AB - The crystal structures, Hirshfeld surface analyses and electrostatic potential surfaces of the di- and tri-hydrates of (5alpha,17E)-17-hydrazonoandrostan-3-ol, 3, namely [3.(H2O)2] and [3.(H2O)3], are reported. The trihydrate, isolated from a solution of 3 in moist methanol, recrystallizes in the orthorhombic space group, P212121, while that of the dihydrate, isolated from a 1:1 aqueous methanol solution, recrystallizes in the monoclinic space group, P21. The asymmetric unit of the trihydrate involves one steroid and three water molecules, while that of the dihydrate has two similar but independent steroid molecules and four hydrate molecules. Very similar conformations are found for the steroid molecules in both hydrates. As expected, the different mole ratios of water: steroid have major influences on the structures. In both cases, complex crystal structures are constructed from various classical hydrogen bonds, involving the hydrate molecules and the hydroxy and hydrazonyl moieties of the steroid. In the trihydrate, there are no direct connections between the steroid molecules, instead the water molecules link the steroid molecules, with only weak van der Waals forces between the steroid molecules. There are some direct links between the steroid molecules in the dihydrate, involving OH(steroid hydroxyl)?O(steroid oxo) hydrogen bonds, in a head to head fashion, and OH?N(hydrazonyl) hydrogen bonds, in a head to tail fashion. However, the major occurrence throughout the structure is of steroid molecules linked by water molecules. PMID- 30273695 TI - Chemical synthesis of C3-oxiranyl/oxiranylmethyl-estrane derivatives targeted by molecular modeling and tested as potential inhibitors of 17beta-hydroxysteroid dehydrogenase type 1. AB - 17beta-Hydroxysteroid dehydrogenase type 1 (17beta-HSD1) is a promising therapeutic target known to play a pivotal role in the progression of estrogen dependent diseases such as breast cancer, and endometriosis. This enzyme is responsible for the last step in the biosynthesis of the most potent estrogen, estradiol (E2) and its inhibition would prevent the growth of estrogen-sensitive tumors. Based on molecular modeling with docking experiments, we identified two promising C3-oxiranyl/oxiranylmethyl-estrane derivatives that would bind competitively and irreversibly in the catalytic site of 17beta-HSD1. They have been synthesized in a short and efficient route and their inhibitory activities over 17beta-HSD1 have been assessed by an enzymatic assay. Compound 15, with an oxiranylmethyl group at position C3, was more likely to bind the catalytic site and showed an interesting, but weak, inhibitory activity with an IC50 value of 1.3 uM (for the reduction of estrone into E2 in T-47D cells). Compound 11, with an oxiranyl at position C3, produced a lower inhibition rate, and the IC50 value cannot be determined. When tested in estrogen-sensitive T-47D cells, both compounds were also slightly estrogenic, although much less than the estrogenic hormone E2. PMID- 30273696 TI - Anti-inflammatory furostanol saponins from the rhizomes of Smilax china L. AB - Seven new furostanol saponins (1-7), chongrenosides A-G, were isolated from the rhizomes of Smilax china L., together with nine known furostanol saponins (8-16). The structures of the new furostanol saponins (1-7) were elucidated by extensive spectroscopic data analyses (1D and 2D NMR, HRESIMS) and chemical evidence. Compounds 1-6 and 8-16 were evaluated for TNF-alpha mRNA expression inhibitory activity on LPS induced RAW264.7 cells. Of them, 1, 4, 6, and 11 inhibited the TNF-alpha mRNA expression by 88%, 87%, 67%, and 93%, respectively, at the concentration of 10 uM. PMID- 30273697 TI - Olfactory function and cognition in relapsing-remitting and secondary-progressive multiple sclerosis. AB - BACKGROUND: Both cognition and olfaction are impaired in multiple sclerosis (MS). However, little is known about the relationship between smell identification ability and measures of cognitive function in this disease. OBJECTIVE: To assess olfactory function in MS and to evaluate its relationship with cognitive and physical disability. METHODS: Fifty-five MS patients and 20 healthy controls (HCs) were tested. The University of Pennsylvania smell identification test (UPSIT) was administered to assess olfactory function. Cognitive function was tested using the symbol digit modalities test (SDMT), California verbal learning test-II (CVLT II), brief visuospatial memory test (BVMT), paced auditory serial addition test (PASAT), and controlled oral word association test (COWAT). Fatigue and depressive symptoms were evaluated using the Modified Fatigue Impact Scale and the Beck Depression Inventory II, respectively. RESULTS: MS patients had lower UPSIT scores than those of the HCs (28.76 +/- 5.48 vs 31.7 +/- 2.18, p = 0.02), with secondary-progressive and cognitively impaired MS patients showing the greatest impairment. Scores on the SDMT, CVLTII, BVMT and COWAT were related to the olfactory test scores. CONCLUSION: We confirm that olfactory function is impaired in MS, particularly in progressive phenotypes, and show, for the first time, that such dysfunction is related to a broad range of cognitive measures. Our data suggest that olfactory dysfunction might be considered as an indirect measure of MS severity. Longitudinal studies are needed to confirm this possibility. PMID- 30273698 TI - A systematic review of DURAL puncture epidural analgesia for labor. AB - STUDY OBJECTIVE: This systematic review aimed to summarize the evidence derived from randomized controlled trials (RCTs) comparing dural puncture epidural analgesia (DPEA) and conventional lumbar epidural analgesia (LEA) for women undergoing labor. INTERVENTIONS: The MEDLINE and EMBASE databases were searched from inception to July 2018 in order to find RCTs published in the English language, which investigated DPEA in laboring women. MAIN RESULTS: Six RCTs were included in the final analysis. Their collective results remain ambiguous. Dural puncture with small (i.e., 26- or 27-gauge) spinal needles seems to confer either minimal benefits or improved analgesic quality and lower pain scores in the first 10 min. Dural puncture with 25-gauge spinal needles has been reported to provide higher success rate than conventional LEA in one trial; however two other studies could only agree on the fact that DPEA results in improved sacral blockade and fewer unilateral blocks compared to LEA. CONCLUSIONS: The current evidence regarding DPEA for labor analgesia remains ambiguous. Future research should investigate the optimal (spinal) needle size for dural puncture as well as factors governing transmeningeal flux of local anesthetics and opioids in the presence of a dural hole. PMID- 30273699 TI - Auditory central gain compensates for changes in cochlear output after prolonged low-level noise exposure. AB - Remarkably, the central auditory system can modify the strength of its sound evoked neural response based on prior acoustic experiences, a phenomenon referred to as central gain. Gain changes are well documented following traumatic noise exposure, but much less is known about central gain dynamics following prolonged exposure to low-level noise, a common acoustic experience in many urban and work environments. We recently reported that the neural output of the cochlea is reduced, while gain was enhanced in the inferior colliculus (IC) following a 5 week exposure to 75 dB noise. To determine if similar effects were present at even lower intensities, we exposed rats to a 65 dB noise expecting to see little to no change in the cochlea or IC. The exposure had little effect on distortion product otoacoustic emissions and did not cause any hair cell loss. However, the amplitude of the CAP, which reflects the neural output of cochlea, was depressed by 50-75%. Surprisingly, neural responses from the IC were enhanced up to 70%, mainly at frequencies within the noise exposure band. One-week post-exposure, CAP amplitudes returned to normal at frequencies within or above the exposure band, whereas responses evoked by frequencies below the exposure band were enhanced by more than 80%. In contrast, IC responses below the exposure frequency were depressed 10-20% whereas responses within the exposure frequency band were enhanced 10-20%. Thus, the central auditory system dynamically up- and down regulates its gain to maintain supra-threshold neural responses within a narrow homeostatic range; a function that likely contributes to the prevention of sounds from being perceived as muffled or too loud. PMID- 30273700 TI - Activation of the unfolded protein response in canine degenerative myelopathy. AB - Canine degenerative myelopathy (DM) is an adult-onset progressive and fatal neurodegenerative disorder. Superoxide dismutase 1 (SOD1) mutations have been reported in affected dogs and immunohistochemical analyses revealed the accumulation of mutant SOD1 (E40K) in spinal neurons and astrocytes. Therefore, this disease is regarded as a unique spontaneous large-animal model of SOD1 mediated amyotrophic lateral sclerosis (ALS) in humans. Recent studies reported that endoplasmic reticulum (ER) stress is a key pathomechanism underlying motor neuron death in ALS. The present study demonstrated the up-regulated expression of the ER stress marker GRP78/BiP (BiP) in the spinal cords of DM-affected dogs. Immunohistochemistry of serial spinal cord sections revealed strong BiP expression in microglia and astrocytes in DM compared to normal control dogs, whereas such difference was not observed in spinal neurons. The results of transcriptional analyses of DM spinal tissues showed increased expression levels of apoptosis signal-regulating kinase 1 (ASK1) and spliced X-box binding protein (XBP1s). E40K-transfected Neuro2A cells expressed higher levels of BiP than wild type SOD1-transfected cells. These results suggest that the activation of the unfolded protein response (UPR) in microglia and astrocytes plays crucial roles in UPR-mediated inflammation in the spinal cords of DM-affected dogs. PMID- 30273701 TI - Neurokinin-1 receptor antagonism improves postoperative neurocognitive disorder in mice. AB - Postoperative neurocognitive disorder (PND) is a major complication in surgical patients, especially the elderly, leading to mild memory impairment after surgery. The underlying pathophysiology remains unknown, although neuroinflammation and blood-brain barrier (BBB) disruption have been increasingly implicated in PND. Emerging evidence suggests that neurokinin-1 receptor (NK-1R), the principal target of proinflammatory neuropeptide substance P (SP), plays a pivotal role in modulating neuroinflammation and BBB integrity. In this study, we used an established mouse model for PND to investigate the effects of a selective NK-1R antagonist L-733,060 on PND-like features after peripheral surgery. Hippocampal SP started to increase at 6 h, peaked at 1 day, and returned to baseline at 3 days after surgery. At 1 day after surgery, NK-1R expression was increased in the hippocampus. At this time point, NK-1R antagonist pretreatment attenuated microgliosis and prevented neutrophil infiltration after surgery. Similarly, proinflammatory cytokines interleukin-1 beta and interleukin-6 were reduced in the hippocampus in NK-1R antagonist-treated mice at 6 h after surgery. Furthermore, surgery-induced BBB disruption, assessed by albumin deposition and expression of tight junction protein claudin-5, was attenuated by NK-1R antagonism at postoperative day 1. Finally, trace fear conditioning test revealed NK-1R antagonism reversed surgery-induced cognitive impairment at 3 days after surgery. Our findings suggest that inhibition of NK-1R signaling protects hippocampus-dependent memory from surgical insult, probably through modulations of neuroinflammation and BBB integrity. PMID- 30273702 TI - Peroxisomicine A1 (toxin T-514) induces cell death of hepatocytes in vivo by triggering the intrinsic apoptotic pathway. AB - Karwinskia parvifolia possesses the highest concentration levels of the anthracenone T-514 (PA1). Studies have demonstrated the induction of apoptosis by PA1 in cancer cell lines. The aim was to investigate the effects of PA1 on the apoptosis of the mouse liver in vivo and its underlying pathway. Sixty CD-1 mice were divided into three groups: untreated, vehicle, and treated with PA1. The animals were euthanized at 4, 8, 12, and 24 h post-treatment. To confirm the toxic effect of PA1 we determined the activity of catalase. Liver sections were prepared for morphological examination and for immunohistochemical evaluation of anti and pro-apoptotic markers. DNA fragmentation was detected by TUNEL assay and electrophoresis. Pre-apoptotic mitochondrial alterations and cytochrome c oxidase activity were analyzed by transmission electron microscopy. PA1 induced pre apoptotic mitochondrial alterations, a high activity of the cytochrome oxidase, and apoptosis in hepatocytes. PA1 caused p53 over-expression and down regulation of PCNA. PA1 also increased the expression levels of the pro-apoptotic markers Bax and Bak, whereas the anti-apoptotic molecule Bcl-2 was decreased. PA1 induces apoptosis by activating the intrinsic mitochondrial apoptotic pathway. These results will be useful for studies regarding the use of PA1 as an antineoplastic agent. PMID- 30273703 TI - Centipede envenomation: Clinical importance and the underlying molecular mechanisms. AB - Centipede bites are usually characterized by mildly to moderately painful encounters with humans, however, they are relatively infrequent. The vast majority of centipede envenomations do not cause severe symptoms and only in very rare cases more serious symptoms such as myocardial ischemia and infarction, hematuria, hemoglobinuria, rhabdomyolysis, hemorrhage, pruritus, eosinophilic cellulitis, as well as anaphylaxis are observed. More prevalent are symptoms including pain, paresthesia, lethargy, localized necrosis, headache, dizziness and nausea. The numerous symptoms and complications elicited by these envenomations indicate that centipede venom possesses an arsenal of chemical components with functional diversity. Centipede venom is a rich and complex natural source of bioactive proteins, peptides and other small molecules that aid in predation or defense. The venom can induce myotoxic, cardiotoxic, neurotoxic and other toxic effects. The constituents target different cellular processes and pathways which in turn trigger a cascade of physiological reactions in the victim. The venom components are potent and selective on peripheral targets; thus, they are valuable in studying the molecular basis of these envenomation symptoms and complications. This review highlights the clinical importance of centipede envenomation and the recent discoveries on the underlying molecular mechanisms of the resulting symptoms which is crucial in therapy. PMID- 30273704 TI - Genotoxicity and cytotoxicity of three microcystin-LR containing cyanobacterial samples from Antioquia, Colombia. AB - The presence of cyanobacterial blooms and cyanotoxins in water presents a global problem due to the deterioration of ecosystems and the possibility of poisoning in human and animals. Microcystin LR is the most widely distributed cyanotoxin and liver cells are its main target. In the present study, HepG2 cells were used to determine DNA damage of three crude extracts of cyanobacterial blooms containing MC-LR, through comet assay. The results show that all extracts at a concentration of 500 MUg mL-1 caused low damage in hepatocytes exposed for 24 h, but produced total mortality even at low concentrations at 48 h. Moreover, balloons corresponding to cell apoptosis were found. Through HPLC/MS, MC-LR was detected in all samples of cyanobacterial blooms at concentrations of (5,65 MUg ml-1) in sample 1, (1,24 MUg ml-1) in sample 2 and (57,29 MUg ml-1) in sample 3. In addition, in all samples high molecular weights peaks were detected, that may correspond to other microcystins. Besides, the cytotoxic effect of a cyanobacterial bloom and some of its chromatographic fractions from the crude extracts were evaluated in U-937, J774, Hela and Vero cell lines, using the enzymatic micromethod (MTT). The highest toxicity was detected in U-937 cells (LC50 = 29.7 MUg mL-1) and Vero cells (LC50 = 39.7 MUg mL-1). Based on these results, it is important to remark that genotoxic and cytotoxicity assays are valuable methods to predict potential biological risks in waters contaminated with blooms of cyanobacteria, since chemical analysis can only describe the presence of cyanotoxins, but not their biological effects. PMID- 30273706 TI - Low serum phosphate and magnesium levels are associated with peripheral neuropathy in patients with type 2 diabetes mellitus. AB - AIMS: To determine the relationship of serum phosphate, serum magnesium and peripheral nerve function in patients with type 2 diabetes mellitus (T2DM). METHODS: A total of 254 patients diagnosed with T2DM were included. Peripheral nerve function was evaluated by nerve conduction study with the use of electromyography. Composite z scores of conduction velocity, latency, and amplitude were constructed, respectively. Demographic, medical and laboratory data including serum phosphate and magnesium were collected. RESULTS: Serum phosphate and serum magnesium levels were significantly lower in patients with diabetic peripheral neuropathy (DPN) (P < 0.01). And the percentages of DPN patients were lower in high tertile of serum phosphate and serum magnesium (P < 0.05). Furthermore, composite z score of conduction velocity (CV) (P = 0.012) were positively associated with serum phosphate levels and the composite z score of amplitude (P < 0.001) and CV (P = 0.041) were positively associated with serum magnesium levels. After adjusting potential related factors (age, gender, smoking, diabetes duration, body mass index, systolic blood pressure, glycated hemoglobin, total cholesterol, estimated glomerular filtration rate), serum levels of phosphate and magnesium were still related to status of DPN in logistic regression (P < 0.05). CONCLUSION: Lower serum phosphate and magnesium significantly correlated with parameters of nerve conduction in T2DM patients. Serum phosphate and magnesium might underlie the pathophysiologic features of DPN. PMID- 30273705 TI - Gelsemium poisoning mediated by the non-toxic plant Cassytha filiformis parasitizing Gelsemium elegans. AB - INTRODUCTION: Gelsemium poisoning is caused by consumption of the deadly Gelsemium species such as Gelsemium elegans, leading to significant gastrointestinal, neurological and cardio-respiratory toxicities. In 2011 (Cluster 1) and 2012 (Cluster 2), the authors encountered two clusters of gelsemium poisoning after consumption of the non-toxic parasitic plant Cassytha filiformis. The current study aims to examine the mechanism of gelsemium poisoning mediated by a benign parasitic plant. METHODS: Qualitative analysis of toxic gelsemium alkaloids using liquid chromatography-tandem mass spectrometry (LC-MS/MS) was performed on the herbal and urine samples from both clusters to confirm exposure. Morphological examination, qualitative analysis of aporphine alkaloids using liquid chromatography-ion trap-time of flight mass spectrometry (LC-IT-TOF/MS) and Sanger sequencing were performed on the plant sample from Cluster 2 to confirm its identity. A field study was conducted in local countryside and C. filiformis was collected for histological, LC-MS/MS and LC-IT TOF/MS analyses to study its interaction with G. elegans. RESULTS: Gelsemium alkaloids that are not naturally present in C. filiformis were detected in the patients' herbal and urine samples. Misidentification and contamination with G. elegans during the preparation process were excluded by morphological examination of the plant sample from Cluster 2. Its identity as C. filiformis was verified with LC-IT-TOF/MS and molecular analyses. Histological, LC-MS/MS and LC-IT-TOF/MS analyses of C. filiformis collected during the field study confirmed that its haustoria penetrated the vascular bundles of G. elegans and absorbed its gelsemium toxins. CONCLUSIONS: The non-toxic plant C. filiformis absorbed toxic gelsemium alkaloids from its host, G. elegans, and led to gelsemium poisoning in our patients. Our study provides new insights into the toxicology of such plants. Benign parasitic plants may lead to potentially life-threatening poisoning if it parasitizes toxic hosts and absorbs their phytotoxins. The public awareness of risks associated with the use of these medicinal parasitic plants should be raised. PMID- 30273707 TI - Petition to replace current OGTT criteria for diagnosing prediabetes with the 1 hour post-load plasma glucose >= 155 mg/dl (8.6 mmol/L). AB - Many individuals with prediabetes, as presently defined, will progress to diabetes (T2D) despite the considerable benefit of lifestyle modification. Therefore, it is paramount to screen individuals at increased risk with a more sensitive method capable of identifying prediabetes at an even earlier time point in the lengthy trajectory to T2D. This petition reviews findings demonstrating that the 1-hour (1-h) postload plasma glucose (PG) >= 155 mg/dl (8.6 mmol/L) in those with normal glucose tolerance (NGT) during an oral glucose tolerance test (OGTT) is highly predictive for detecting progression to T2D, micro- and macrovascular complications and mortality in individuals at increased risk. Furthermore, the STOP DIABETES Study documented effective interventions that reduce the future risk of T2D in those with NGT and a 1-h PG >= 155 mg/dl (8.6 mmol/L). The 1-h OGTT represents a valuable opportunity to extend the proven benefit of diabetes prevention to the sizeable and growing population of individuals at increased risk of progression to T2D. The substantial evidence provided in this petition strongly supports redefining current diagnostic criteria for prediabetes with the elevated 1-h PG level. The authors therefore advocate a 1-h OGTT to detect prediabetes and hence, thwart the global diabetes epidemic. PMID- 30273708 TI - Cost-effectiveness of a faith-based lifestyle intervention for diabetes prevention among African Americans: A within-trial analysis. AB - AIMS: We assessed costs and cost-effectiveness of implementing Fit Body and Soul (FBAS), a church-based 18-session lifestyle education intervention for African Americans. METHODS: We calculated incremental cost-effectiveness ratios (ICER) using data from a cluster randomized controlled trial comparing FBAS with health education (HE) among 604 overweight participants in 20 churches. The ICER was the adjusted difference in costs to deliver FBAS versus HE over the difference in weight change (kilograms [kg]) at one-year follow-up. Costs included those incurred for participant identification and program implementation. We fitted linear mixed-effects regression models, accounting for clustering of participants within churches and for age, sex, and educational attainment. We repeated these analyses for secondary outcomes (waist circumference [cm], physical activity [MET], glucose, blood pressure, and quality of life). RESULTS: Per-person intervention cost of FBAS was $50.39 more than HE ($442.22 vs. $391.83 per person), and adjusted differences in weight change (1.9 kg [95% CI: 1.0 to 2.8]) and waist circumference (2.4 cm [95% CI: 1.3 to 3.4]) were both significant. FBAS did not result in statistically significant differences in physical activity, glucose, blood pressures, or quality of life. We estimated that compared to HE, FBAS costs an additional $26.52 per kg weight lost and $21.00 per cm reduction in waist circumference. CONCLUSIONS: For a modest increase in cost, FBAS led to greater weight and waist reductions among African Americans in a church setting. ClinicalTrials.gov Identifier NCT01730196. PMID- 30273711 TI - Precision gaming for health: Computer games as digital medicine. AB - Health based games have significant potential as therapeutic interventions due to the inherent mechanisms associated with social and individual game play and their capacity for sensor integration, data capture analysis and patient feedback. Moreover, they are low cost and they can be deployed at the point of care across an evolving digital ecosystem. However, a robust evidence base to support their wider adoption as a clinical intervention for chronic diseases is lacking and significant methodological barriers exist for health games developers creating efficacious 'digital medicines'. Game design is complex and it must utilise validated game mechanics balanced with a creative and engaging game design. The aim of this review is therefore to outline the fundamental steps of game development for health professionals and to critically appraise the methodology for assessing health games as medical interventions. This requires (1) The adoption of clearly defined global language for health games development based on a targeted function as therapeutic agents. (2) The development of multidisciplinary teams with a broad portfolio of development and clinical skill sets. (3) The creation of health game engines specifically built to facilitate clinical game development. (4) Robust trial design and assessment of translational impact: If games are to be prescribed, their efficacy and toxicity must be based on a rigorous assessment of their use within a real world clinical environment. Trials for precision health games have specific challenges around blinding, learning curves, bias and confounding that are particularly problematic. We propose the adoption of the IDEAL-GAMES framework for game development that systematically assess and validates games through open registries. In conclusion we propose a new framework for assessing the robustness and clinical efficacy of games for health as clinical interventions in the clinical environment. PMID- 30273712 TI - Morphological study of the ovary in Hanseniella caldaria (Myriapoda; Symphyla): The position of oocyte-growth and evolution of ovarian structure in Arthropoda. AB - In Arthropoda, the ovary is classified into Chelicerata-type and Mandibulata type, based on the oocyte-growth position within the ovary. By contrast, oocytes of Diplopoda and Chilopoda grow within the hemocoelic space. However, as the position of oocyte-growth in Symphyla and Pauropoda has not been confirmed, whether the hemocoelic nature of oocyte-growth is common among myriapods remains ambiguous. This study described the ovarian structure of Hanseniella caldaria to reveal the oocyte-growth position in Symphyla. The oocyte is surrounded by the follicle epithelium, and the inner surface of the follicle epithelium, i.e., the space between follicle cells and oocytes, is lined with a basement membrane. The follicle epithelial layer continues to the ovarian epithelium via the follicle extension with a continuous layer of basement membrane. Data on the architecture of the follicle suggest that the follicle pouch opens to the hemocoel. Hence, the oocyte of H. caldaria grows within the hemocoelic space. Based on our findings in H. caldaria and previous studies in a millipede and in centipedes, the hemocoelic nature of oocyte-growth is considered as a common feature among myriapods and a synapomorphy of the Myriapoda for which morphological synapomorphies have been ambiguous. PMID- 30273710 TI - Unexpected relevant role of gene mosaicism in patients with primary immunodeficiency diseases. AB - BACKGROUND: Postzygotic de novo mutations lead to the phenomenon of gene mosaicism. The 3 main types are called somatic, gonadal, and gonosomal mosaicism, which differ in terms of the body distribution of postzygotic mutations. Mosaicism has been reported occasionally in patients with primary immunodeficiency diseases (PIDs) since the early 1990s, but its real involvement has not been systematically addressed. OBJECTIVE: We sought to investigate the incidence of gene mosaicism in patients with PIDs. METHODS: The amplicon-based deep sequencing method was used in the 3 parts of the study that establish (1) the allele frequency of germline variants (n = 100), (2) the incidence of parental gonosomal mosaicism in families with PIDs with de novo mutations (n = 92), and (3) the incidence of mosaicism in families with PIDs with moderate-to high suspicion of gene mosaicism (n = 36). Additional investigations evaluated body distribution of postzygotic mutations, their stability over time, and their characteristics. RESULTS: The range of allele frequency (44.1% to 55.6%) was established for germline variants. Those with minor allele frequencies of less than 44.1% were assumed to be postzygotic. Mosaicism was detected in 30 (23.4%) of 128 families with PIDs, with a variable minor allele frequency (0.8% to 40.5%). Parental gonosomal mosaicism was detected in 6 (6.5%) of 92 families with de novo mutations, and a high incidence of mosaicism (63.9%) was detected among families with moderate-to-high suspicion of gene mosaicism. In most analyzed cases mosaicism was found to be both uniformly distributed and stable over time. CONCLUSION: This study represents the largest performed to date to investigate mosaicism in patients with PIDs, revealing that it affects approximately 25% of enrolled families. Our results might have serious consequences regarding treatment and genetic counseling and reinforce the use of next-generation sequencing-based methods in the routine analyses of PIDs. PMID- 30273713 TI - Review: In vitro generation of red blood cells for transfusion medicine: Progress, prospects and challenges. AB - In vitro generation of red blood cells (RBCs) has the potential to circumvent the shortfalls in global demand for blood for transfusion applications. The conventional approach for RBC generation has been from differentiation of hematopoietic stem cells (HSCs) derived from cord blood, adult bone marrow or peripheral blood. More recently, RBCs have been generated from human induced pluripotent stem cells (hiPSCs) as well as from immortalized adult erythroid progenitors. In this review, we highlight the recent advances to RBC generation from these different approaches and discuss the challenges and new strategies that can potentially make large-scale in vitro generation of RBCs a feasible approach. PMID- 30273715 TI - A simple geometric analysis method for measuring and mitigating RF induced currents on Deep Brain Stimulation leads by multichannel transmission/reception. AB - The purpose of this work is to present a new method that can be used to estimate and mitigate RF induced currents on Deep Brain Stimulation (DBS) leads. Here, we demonstrate the effect of RF induced current mitigation on both RF heating and image quality for a variety of brain MRI sequences at 3 T. We acquired pre-scan images around a DBS lead (in-situ and ex-vivo) using conventional Gradient Echo Sequence (GRE) accelerated by parallel imaging (i.e GRAPPA) and quantified the magnitude and phase of RF induced current using the relative location of the B1+ null with respect to the lead position. We estimated the RF induced current on a DBS lead implanted in a gel phantom as well as in a cadaver head study for a variety of RF excitation patterns. We also measured the increase in tip temperature using fiber-optic probes for both phantom and cadaver studies. Using the magnitude and phase information of the current induced separately by two transmit channels of the body coil, we calculated an implant friendly (IF) excitation. Using the IF excitation, we acquired T1, T2 weighted Turbo Spin Echo (TSE), T2 weighted SPACE-Dark Fluid, and Ultra Short Echo Time (UTE) sequences around the lead. Our induced current estimation demonstrated linear relationship between the magnitude of the induced current and the square root SAR at the tip of the lead as measured in phantom studies. The "IF excitation pattern" calculated after the pre-scan mitigated RF artifacts and increased the image quality around the lead. In addition, it reduced the tip temperature significantly in both phantom and cadaver studies compared to a conventional quadrature excitation while keeping equivalent overall image quality. We present a relatively fast method that can be used to calculate implant friendly excitation, reducing image artifacts as well as the temperature around the DBS electrodes. When combined with a variety of MR sequences, the proposed method can improve the image quality and patient safety in clinical imaging scenarios. PMID- 30273714 TI - Neural correlates of developing theory of mind competence in early childhood. AB - Theory of mind (ToM) encompasses a range of abilities that show different developmental time courses. However, relatively little work has examined the neural correlates of ToM during early childhood. In this study, we investigated the neural correlates of ToM in typically developing children aged 4-8 years using resting-state functional magnetic resonance imaging. We calculated whole brain functional connectivity with the right temporo-parietal junction (RTPJ), a core region involved in ToM, and examined its relation to children's early, basic, and advanced components of ToM competence assessed by a parent-report measure. Total ToM and both basic and advanced ToM components, but not early, consistently showed a positive correlation with connectivity between RTPJ and posterior cingulate cortex/precuneus; advanced ToM was also correlated with RTPJ to left TPJ connectivity. However, early and advanced ToM components showed negative correlation with the right inferior/superior parietal lobe, suggesting that RTPJ network differentiation is also related to ToM abilities. We confirmed and extended these results using a Bayesian modeling approach demonstrating significant relations between multiple nodes of the mentalizing network and ToM abilities, with no evidence for differences in relations between ToM components. Our data provide new insights into the neural correlates of multiple aspects of ToM in early childhood and may have implications for both typical and atypical development of ToM.

PMID- 30273717 TI - Concordance Between Proxy Level of Care Preference and Advance Directives Among Nursing Home Residents With Advanced Dementia: A Cluster Randomized Clinical Trial. AB - CONTEXT: Care consistent with goals is the desired outcome of advance care planning (ACP). OBJECTIVES: The objectives of this study were to examine concordance between advance directives and proxy care preferences among nursing home residents with advanced dementia and to determine the impact of an ACP video on concordance. METHODS: Data were from Educational Video to Improve Nursing home Care in End-stage dementia, a cluster randomized clinical trial conducted in 64 Boston-area facilities (32/arm) from 2013 to 2017. Participants included advanced dementia residents and their proxies (N = 328 dyads). At the baseline and quarterly (up to 12 months), proxies stated their preferred level of care for the resident (comfort, basic, or intensive) and advance directives for specific treatments (resuscitation, hospitalization, tube-feeding, intravenous hydration, antibiotics) were abstracted from the charts. At the baseline, proxies in intervention facilities viewed an ACP video. Their care preferences after viewing it were shared via a written communication with the primary care team. At each assessment, concordance between directives and proxy preferences was determined. RESULTS: Among the residents (mean age, 86.6 years; 19.5% male), the most prevalent directive was DNR (89.3%) and foregoing antibiotics was least common (parenteral, 8.2%; any type, 4.0%). Concordance between directives and each level of care preference was as follows: comfort, 7%; basic, 49%; and intensive, 58%. When comfort care was preferred, concordance was higher in intervention versus control facilities (10.8% vs. 2.5%; adjusted odds ratio, 2.48; 95% CI, 1.01 6.09). CONCLUSION: Better alignment between preferences for comfort-focused care and advance directives is needed in advanced dementia. An ACP video may help achieve that goal.

PMID- 30273719 TI - Rapid respiratory transition at birth as evaluated by electrical activity of the diaphragm in very preterm infants supported by nasal CPAP. AB - OBJECTIVE: To investigate breathing patterns during respiratory adaptation in preterm infants using the electrical activity of the diaphragm (EAdi) signal. PATIENTS: Infants born between 28 + 0 and 31 + 6 gestational weeks and supported by early nasal continuous positive airway pressure (nCPAP) were studied. The EAdi signal was recorded for 120 min after birth. RESULTS: Eight preterm infants were evaluated. The median EAdi peak value of 19.2 MUV (lower quartile 13.1; upper quartile 22.2) at 20 min after birth decreased to 11.4 MUV (9.5-14.7) at 55 min of age. The median EAdi minimum value of 4.5 MUV (2.2-5.5) at 25 min after birth decreased to 1.6 MUV (1.2-2.7) at 85 min of age. CONCLUSION: EAdi was high right after birth. This indicates that preterm infants are capable of generating sufficient respiratory drive and diaphragm tone during expiration to establish and maintain functional residual capacity. Diaphragm activity decreased within the first 90 min, suggesting that early adaptation was accomplished by 90 min of age. PMID- 30273720 TI - Endovascular treatment of Vertebral-Venous Fistula with flow diverting stent: A Case Report. AB - BACKGROUND: Vertebral-venous fistulas (VVF) are a rare vascular condition and are commonly associated with trauma, but may also be idiopathic, spontaneous or congenital. A current literature review reveals there is no level 1 evidence or established guidelines on optimal treatment for VVF. Diagnosis is often confirmed by catheter cerebral angiogram. Treatment goals are complete occlusion of the fistula, which can be achieved by both endovascular closure and/or surgical ligation treatment. Telescopic Pipeline flow diversion stents are a common treatment modality for aneurysms and have also been described to successfully treat different types of cranial arteriovenous fistulas (AVF) including carotid cavernous fistulas (CCF).There is however no English literature available regarding its use in the management of vertebral-venous fistulas (VVF), which is a rare entity. CASE DESCRIPTION: The authors present a case of VVF, which is the first reported case to their knowledge whereby a Pipeline flow diverting stent has been used to successfully treat a VVF, whilst preserving the parent vertebral artery. The authors describe both the advantages and limitations of this approach. CONCLUSIONS: This case report highlights the potential of flow diversion stents in the treatment of VVF. This technique was shown to be a safe and effective method of treatment for VVF. Important limitations however need to be considered prior to this form of treatment for VVF, including the need for multiple devices, extended duration of treatment and associated increased costs involved. PMID- 30273721 TI - Intracranial Dural Parafalcine Chondroma: Case Report and Systematic Review of the Literature. AB - Intracranial chondromas are rare, benign neoplasms representing only 0.2%-0.3% of neoplastic intracranial lesions. They commonly originate from the skull base but can infrequently arise from the falx, convexity dura, or ventricular ependyma. Diagnosis requires histopathologic confirmation, as patients present with nonspecific symptoms related to mass effect, and imaging characteristics often resemble meningiomas, oligodendrogliomas, and vascular malformations. We describe the case of a patient harboring a parafalcine dural chondroma that was discovered incidentally and was managed surgically at our institution. We also provide a systematic review of the literature to elucidate incidence, origin, imaging findings, surgical management approaches, and prognosis of this rare tumor. PMID- 30273722 TI - Moderate Sedation for Pipeline Embolization of Posterior Circulation Disease: Technical Note from a Single Center. AB - OBJECTIVE: Flow diversion has been an important addition to endovascular neurosurgery, but its use in the posterior circulation remains controversial. Our goal is to describe the safety and efficacy of moderate sedation during flow diversion for posterior circulation lesions (aneurysms or dissecting pseudoaneurysms). METHODS: The authors retrospectively reviewed the medical records of all patients who underwent placement of a Pipeline embolization device for a posterior circulation lesion from August 2012 through November 2017. Clinical information and outcomes were evaluated. RESULTS: Fifteen consecutive patients were identified: 8 female, 7 male (mean age 52.2+/-16.3 years, range 15 81). Eleven lesions were located in the vertebral artery, 1 in the posterior inferior cerebellar artery aneurysm, two in the posterior cerebral artery, and one in the basilar artery. All patients underwent flow diversion with Pipeline embolization devices. One patient experienced an acute occlusion of the basilar artery during the procedure that required revascularization. Mean fluoroscopy time was 35.6+/-16.5 minutes (range 15.5-75). Mean follow-up time was 12.7+/-8.8 months (range 3-36). No patient had new neurological deficits in the perioperative or postoperative period. Conversion to general anesthesia was not required in any case. CONCLUSIONS: Moderate sedation is safe and feasible in patients undergoing flow diversion for posterior circulation lesions. Additionally, its use may allow for more rapid identification of procedural complications, facilitating emergent treatment and decreasing procedure-related morbidity. PMID- 30273723 TI - Sealing hyaluronic acid microgels with oppositely-charged polypeptides: A simple strategy for packaging hydrophilic drugs with on-demand release. AB - A simple route to deliver on demand hydrosoluble molecules such as peptides, packaged in biocompatible and biodegradable microgels, is presented. Hyaluronic acid hydrogel particles with a controlled structure are prepared using a microfluidic approach. Their porosity and their rigidity can be tuned by changing the crosslinking density. These negatively-charged polyelectrolytes interact strongly with positively-charged linear peptides such as poly-l-lysine (PLL). Their interactions induce microgel deswelling and inhibit microgel enzymatic degradability by hyaluronidase. While small PLL penetrate the whole volume of the microgel, PLL larger than the mesh size of the network remain confined at its periphery. They make a complexed layer with reduced pore size, which insulates the microgel inner core from the outer medium. Consequently, enzymatic degradation of the matrix is fully inhibited and non-affinity hydrophilic species can be trapped in the core. Indeed, negatively-charged or small neutral peptides, without interactions with the network, usually diffuse freely across the network. By simple addition of large PLL, they are packaged in the core and can be released on demand, upon introduction of an enzyme that degrades selectively the capping agent. Single polyelectrolyte layer appears as a simple generic method to coat hydrogel-based materials of various scales for encapsulation and controlled delivery of hydrosoluble molecules. PMID- 30273724 TI - Dual and multiple stimuli-responsive platonic micelles bearing disaccharides. AB - We recently identified completely monodisperse micelles whose aggregation number (Nagg) coincides with the vertex number of regular polyhedra, named Platonic micelles. The combination of both the micellar properties and controlling their structures by external stimuli could be promising for producing precisely controlled self-assembled structures. From this perspective, we newly synthesized a calix[4]arene-based amphiphile bearing disaccharides, cellobioses. The crowded and bulky structure in the hydrophilic group could provide a novel stimuli responsiveness of disaccharides in amphiphiles. The aggregation behavior such as the morphologies and the aggregation number of the calix[4]arene-based micelle was characterized using small angle scattering techniques and analytical ultracentrifugation measurements. Owing to hydrogen bonding among the disaccharide, the head volume became smaller than expected, resulting in the formation of cylindrical ones. However, cleaving the hydrogen bond by controlling temperature or pH induced morphological transition of the micellar structure from cylindrical to spherical. The dual-stimuli (temperature and pH) generated smaller micelles with Nagg of 12. Interestingly, when the amphiphile formed spherical micelles at various conditions, the Nagg matched the Platonic number, and the change of Nagg in response to the external stimuli was non-continuous, which is consistent with the concept of Platonic micelles. PMID- 30273725 TI - Association of fine particulate matter on acute exacerbation of chronic obstructive pulmonary disease in Yancheng, China. AB - BACKGROUND: Epidemiological evidence on the association between short-term exposure to fine particulate matter (PM2.5) air pollution and acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is limited in China. OBJECTIVES: To explore the associations between PM2.5 and AECOPD in Yancheng, China from 2015 to 2017. METHODS: In this time-series study, we used a generalized linear model with quasi-Poisson regression to investigate the association between PM2.5 and AECOPD admitted in two major hospitals in Yancheng. We tested the robustness of the associations using two-pollutant models and examined the potential effect modification by age, gender and season via stratification analyses. Lastly, we fitted the concentration-response curves. RESULTS: We identified a total of 4761 AECOPD inpatients during the study period. The average daily-mean PM2.5 concentration was 45.2 MUg/m3. Each 10 MUg/m3 increase in PM2.5 concentration on the concurrent day of the onset of AECOPD was associated with a 1.05% (95% confidence interval: 0.14%, 1.96%) increase in AECOPD. The association was robust to the adjustment of ozone, but not to sulfur dioxide, nitrogen dioxide, and carbon monoxide. The association was larger in females, elderly patients, and was restricted within the cold season, but all between-group differences were insignificant. The concentration-response relationship curves were generally linear but flatted at concentrations over 40 MUg/m3. CONCLUSIONS: This study demonstrated a higher risk of AECOPD associated with present-day PM2.5 exposure in a Chinese city. We further provided important information on lag patterns, susceptible subgroups, sensitive seasons, as well as the characteristics of the concentration-response relationship curves. PMID- 30273726 TI - Acute and chronic effects of ambient fine particulate matter on preterm births in Beijing, China: A time-series model. AB - Accumulating evidence suggests that short- and long-term exposure to ambient fine particulate matter <= 2.5 MUm (PM2.5) during pregnancy is associated with preterm births, yet the results are inconsistent, and the shape of the exposure-response curve is unclear, partially due to the limited studies conducted in areas with high air pollution. Our study evaluated the association between ambient PM2.5 concentration and preterm births in Beijing, China. Daily preterm birth data were collected from a hospital in Beijing during 2006 to 2013; a time-series of daily PM2.5 concentrations during the same period is assembled with measured data at three monitoring sites in Beijing. An extension of the Poisson regression and a time-series model were applied to simultaneously estimate the acute and chronic effects of exposure to PM2.5, with mutual adjustment for short- and long-term exposure as well as for confounders. During the study period, the PM2.5 concentration was 70.4 +/- 60.6 MUg/m3 and was found to be associated with an increased risk of preterm birth. In the study cohort, a 0.52% (95% confidence interval, CI: 0.09%, 0.96%) and 3.13% (95%CI: 1.92%, 4.35%) increase in preterm births was estimated for each 10-MUg/m3 increase in short- and long-term exposure, respectively. This association was significantly modified by season (p < 0.05). With mutual adjustments for short- and long-term exposure, a more robust association (3.16%, 95% CI: 1.95%, 4.39%; per 10-MUg/m3 increment in PM2.5) was observed for chronic effects. The exposure-response relationships for both short- and long-term exposure were linear, without a threshold, over the relatively low exposure range and flattened out at higher concentration levels. The maximum effect for long-term exposure to PM2.5 (33.6%) was much greater than that for short-term exposure (19.9%). These findings indicate that air quality improvements over a long period could yield significant health benefits.

AB - Coking wastewater is used to prepare coal slurry, which can be used as combustion and gasification fuel. This promising technology simultaneously achieves resource utilization and wastewater management. Slurrying properties are essential to the industrial application of coal slurry. These properties are considerably influenced by coal surface properties and the adsorption of an additive by coal. In this study, the effects of the internal components (e.g., phenol, ammonia nitrogen, and metal ions) of coking wastewater on the adsorption of an additive by coal and on coal surface properties were measured. Results showed that the competitive adsorption between phenol and the additive reduced the amount of additive adsorbed on coal. However, phenol acted as an additive to improve the wettability of coal particles. Cations (Ca2+, NH4+, and Na+) adversely affected the slurrying because they weakened the negative charges of coal. Furthermore, a large amount of water was adsorbed due to the ionic bonding effects, thereby reducing the free water in the coal slurry system. The maximum slurrying concentration of CWCS was 0.8 percentage points higher than that of CWS, suggesting that coking wastewater enhanced the slurrying capability of the coal slurry by integrating the various effects induced by the different internal components. PMID- 30273728 TI - Ordered diatom species loss along a total phosphorus gradient in eutrophic lakes of the lower Yangtze River basin, China. AB - As global changes begin to affect the biosphere profoundly, the impacts on ecosystem health will become more significant. Understanding the sequence of functional species loss along an environmental or ecological gradient remains a research priority for ecosystem conservation. In this paper, nestedness, beta diversity and its components in diatom communities are used as ecological indicators of the dynamic change in functional species along environment gradients in 76 lakes of the lower Yangtze River basin, China. The results indicate that species turnover is typically the dominant component of beta diversity and that the influence of nestedness is generally low. However, changes in nestedness denote a significant threshold of lake eutrophication at a total phosphorus (TP) level of 0.06 mg/l, which is lower than the threshold indicated by diatom diversity. This finding was coupled with theoretical predictions about the successive proportional loss of 'canary' and 'keystone' species, which are replaced by 'weedy' species. These results show that nestedness of diatom communities can provide an additional metric for evaluating lake ecosystem health in this region. As management targets for nutrient control have already been introduced in the region, a revision of the identified critical phosphorus level (i.e., TP = 0.087-0.1 mg/l) to TP = 0.06 mg/l is proposed to keep lakes under low risk. PMID- 30273729 TI - Evaluation of the ecological protective effect of the "large basin" comprehensive management system in the Tarim River basin, China. AB - It is very important to construct a reasonable and efficient basin management system to meet the ecological water demand in arid areas with natural vegetation, and to maintain the integrity and stability of fragile ecosystems. However, how to assess the effect of basin management on ecological protection in arid areas as well as how to achieve the optimal control and efficient use of ecological water are major issues for many researchers and river basin managers. To address these two questions, we investigated the comprehensive management system for the Tarim River basin in China as a typical case study. The results showed that the natural vegetation coverage degree, the ecological water supply, temperature vegetation dryness index (TVDI), and the tree-ring chronology of Populus euphratica increased, whereas the disturbance of water resources by human activities decreased. Therefore, the effects of ecological protection were obvious after comprehensive "large basin" management. Based on an innovative application of tree-ring chronology to estimate the water leakage from the river, we determined the minimum runoff level (43.1 * 108 m3) when the natural vegetation needs to overflow. To further improve the effect of comprehensive management, the optimal regulation mode (i.e. maintaining the groundwater depth at 2-6 m, and the frequency and duration of overflowing at 2-3 times per year for a duration of 15-20 days during July to September) for the ecological sluices was formulated from the perspective of the efficient utilization of ecological water. These results provide a scientific reference for constructing reasonable management systems for similar river basins in arid areas. PMID- 30273730 TI - Using spatio-temporal fusion of Landsat-8 and MODIS data to derive phenology, biomass and yield estimates for corn and soybean. AB - The Simple Algorithm for Yield estimates (SAFY) is a crop yield model that simulates crop growth and biomass accumulation at a daily time step. Parameters in the SAFY model can be determined from literature, in situ measurements, or optical remote sensing data through data assimilation. For effective determination of parameters, optical remote sensing data need to be acquired at high spatial and high temporal resolutions. However, this is challenging due to interference of cloud cover and rather long revisiting cycles of high resolution satellite sensors. Spatio-temporal fusion of multi-source remote sensing data may represent a feasible solution. Here, crop phenology-related parameters in the SAFY model were derived using an improved Two-Step Filtering (TSF) model from remote sensing data generated through spatio-temporal fusion of Landsat-8 and Moderate Resolution Imaging Spectroradiometer (MODIS) data. Remaining parameters were determined through an optimization procedure using the same dataset. The SAFY model was then used for dry aboveground biomass and yield estimation at a subfield scale for corn (Zea mays) and soybean (Glycine max). The results show that the improved TSF method is able to determine crop phenology stages with an error of <5 days. After calibration, the SAFY model can reproduce daily Green Leaf Area Index (GLAI) effectively throughout the growing season and estimate crop biomass and yield accurately at a subfield scale using three Landsat-8 and 10 MODIS images acquired for the season. This approach improves the accuracy of biomass estimation by about 4% in relative Root Mean Square Error (RRMSE), compared with the SAFY model without forcing the phenology-related parameters. The RMSE of yield estimation is 146.33 g/m2 for corn and 82.86 g/m2 for soybean. The proposed framework is applicable for local-scale or field-scale phenology detection and yield estimation. PMID- 30273731 TI - Manganese release linked to carbonate dissolution during the start-up phase of a subsurface iron removal well in Khabarovsk, Russia. AB - Subsurface iron removal (SIR) is a proven pre-treatment technology for removing dissolved iron and manganese from groundwater. The start-up phase of a SIR well and the proper development of the reaction zone around the well are crucial for its subsequent performance. This study evaluates the start-up phase of a SIR production well in Khabarovsk, Russia during the first 194 SIR cycles. A strong release of manganese was observed, which led to concentrations twice as high as the background value of the pristine groundwater. Regular monitoring of the production well and its three adjacent observation wells showed that iron removal began immediately after start-up and that the reaction zone was completely formed within 25 SIR cycles. Closed-bottle batch tests and a flow-through leaching test revealed that the grain size of the aquifer material and groundwater pH are the primary controls on manganese release. During infiltration phases the dissolution of manganese-bearing carbonate minerals was caused by direct oxidation by O2, whereas the low groundwater pH of 6 seemed to be responsible for the manganese release during extraction. PMID- 30273732 TI - Humboldt penguins' feathers as bioindicators of metal exposure. AB - Avian feathers have the potential to accumulate trace elements originating from contaminated food and polluted environments. In fact, in feathers, metals bind to keratin, a sulphur-containing protein for which several metals have a strong affinity. Here, the concentrations of 18 essential and non-essential elements were investigated in a Humboldt penguin (Spheniscus humboldti) colony housed at the Acquario di Cattolica (Italy). This species is listed as vulnerable in the Red List of the International Union for Conservation of Nature. According to the literature, there is usually a link between metal levels in the diet of birds and levels detected in their feathers. Thus, metals were also determined in the penguins' food (capelin, Mallotus villosus). We hypothesize that the controlled conditions in which birds are kept in captivity, and the homogeneous diet that they follow could allow a better understanding of metal bioaccumulation (such as mercury) or bio-dilution (such as arsenic) in the marine food chain, indicated by penguins' feathers. Moreover, comparisons with our previous investigations performed on an ex-situ African penguin (Spheniscus demersus) colony suggest that penguins living indoors have lower body burden of metals than those living outdoors. Indeed, environmental contaminants usually found in areas subjected to anthropogenic impact, where zoos and aquaria are often located, are not accumulated to levels of concern. PMID- 30273733 TI - Effects of urban growth spatial pattern (UGSP) on the land surface temperature (LST): A study in the Po Valley (Italy). AB - Sealed surfaces greatly influence Urban Heat Island (UHI) effects. In this respect, both the composition and spatial patterns of anthropogenic land use play an important role in local thermal pattern. The urban environments' climate change adaptation strategy needs adequate knowledge systems urban planners can use to organise and design more resistant and resilient urban spaces. This study examined the relationship between Land Surface Temperature (LST) variations and increasing urbanised areas during the period 2001-2011 in the Po Valley, utilising different urban growth spatial patterns (UGSP). Remotely sensed LST data was obtained from MODIS (MODerate Resolution Imaging Spectroradiometer) at a resolution of 1 km/pixel for an 11 year-period, from 2001 to 2011, with urbanisation data from the ISTAT map (nominal scale 1:10,000) respectively for the 2001 and 2011 time sections. The relationship between dependent (mean annual daytime, nighttime and daily values) and independent (urbanised areas) variables were investigated through ANOVA test and post-hoc analysis (p < 0.01) for all defined UGSP. Results showed that there is a decreasing LST range (in all conditions) associated with progressive increase of urbanised areas. Furthermore, clustered patterns urban growth have a statistically significant relationship with daytime, nighttime and daily conditions while dispersed pattern urban growth have the same with nighttime only. The outcomes are helpful for understanding the effects of different UGSP, which have significant implications for urban planning, and identifying the critical territorial sectors in need of sustainable mitigation actions. PMID- 30273735 TI - Anti-melanogenic effects of oyster hydrolysate in UVB-irradiated C57BL/6J mice and B16F10 melanoma cells via downregulation of cAMP signaling pathway. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Pacific oyster (Crassostrea gigas) has been used to treat pigmentary disorders such as freckles, melasma, and moles in Korea. AIM OF THE STUDY: We aimed to investigate the inhibitory effects of oyster hydrolysate (OH) on melanogenesis in B16F10 melanoma cells and UVB-irradiated C57BL/6J mice. MATERIAL AND METHODS: The molecular weight distribution and peptide sequences of OH were detected using MALDI-TOF and UHPLC. To evaluate the anti-melanogenic effects of OH, cell viability, melanin content, tyrosinase activity, intracellular cyclic adenosine monophosphate (cAMP) and protein expressions levels were measured in B16F10 cells. In addition, OH was orally administered to UVB-irradiated mice for 9 weeks. After sacrificing the mice, the whitening effects of OH were evaluated based on histological observations and protein expression levels. RESULTS: In B16F10 cells, OH decreased melanin content and tyrosinase activity in a dose-dependent manner. OH exhibited anti-melanogenic activities via downregulation of cAMP signaling pathway, which consequently decreased melanin synthesis. In UVB-irradiated mice groups, OH decreased the number of active melanocytes and melanin granules. The expression of tyrosinase related proteins and microphthalmia-associated transcription factor (MITF) decreased in the OH-administered groups. CONCLUSIONS: These results show that OH inhibits melanin synthesis in B16F10 cells via downregulation of cAMP signaling pathway and in UVB-irradiated mice, by decreasing the number of active melanocytes and melanin granules. PMID- 30273709 TI - Allergic Rhinitis and its Impact on Asthma (ARIA) Phase 4 (2018): Change management in allergic rhinitis and asthma multimorbidity using mobile technology. AB - Allergic Rhinitis and its Impact on Asthma (ARIA) has evolved from a guideline by using the best approach to integrated care pathways using mobile technology in patients with allergic rhinitis (AR) and asthma multimorbidity. The proposed next phase of ARIA is change management, with the aim of providing an active and healthy life to patients with rhinitis and to those with asthma multimorbidity across the lifecycle irrespective of their sex or socioeconomic status to reduce health and social inequities incurred by the disease. ARIA has followed the 8 step model of Kotter to assess and implement the effect of rhinitis on asthma multimorbidity and to propose multimorbid guidelines. A second change management strategy is proposed by ARIA Phase 4 to increase self-medication and shared decision making in rhinitis and asthma multimorbidity. An innovation of ARIA has been the development and validation of information technology evidence-based tools (Mobile Airways Sentinel Network [MASK]) that can inform patient decisions on the basis of a self-care plan proposed by the health care professional. PMID- 30273736 TI - In vitro antiplasmodial, antitrypanosomal and antileishmanial activities of selected medicinal plants from Ugandan flora: Refocusing into multi-component potentials. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Seven medicinal plants from Ugandan flora, namely Entada abyssinica, Khaya anthotheca, Vernonia amygdalina, Baccharoides adoensis, Schkuhria pinnata, Entandropragma utile and Momordica foetida, were selected in this study. They are used to treat conditions and infections ranging from inflammations, pains and fevers to viruses, bacteria, protozoans and parasites. Two of the plants, V. amygdalina and M. foetida, are also used as human food or relish, while others are important in ethnoveterinary practices and in zoopharmacognosy in the wild. The aim of this study was to evaluate the in vitro antiplasmodial, antitrypanosomal and antileishmanial activities, along with cytotoxicity of the multi-component extracts of these plants. MATERIALS AND METHODS: Different parts of the plants were prepared and serially extracted with hexane, petroleum ether, dichloromethane, ethyl acetate, methanol and double distilled water. Solvent free extracts were assayed for in vitro inhibition against four reference parasite strains, Plasmodium falciparum (K1), Trypanosoma brucei rhodesiense (STIB 900), Trypanosoma cruzi (Talahuen C2C4) and Leishmania donovani (MHOM-ET-67/L82) using standard methods. Toxicity was assessed against L6 skeletal fibroblast and mouse peritoneal macrophage (J774) cells and selectivity indices (SIs) calculated for the most active extracts. RESULTS: The strongest activities, demonstrating median inhibitory concentration (IC50) values <= 2 MUg/ml, were observed for the dichloromethane and petroleum ether extracts of K. anthotheca, B. adoensis and S. pinnata. Overall, IC50 values ranged from < 1 MUg/ml to > 90 MUg/ml. Out of 22 extracts demonstrating IC50s < 20 MUg/ml, seven were against T. b. rhodesiense (IC50: 1.6-16.2 MUg/ml), six against T. cruzi (IC50: 2.1-18.57 MUg/ml), none against L. donovani (IC50: falling > 3.3 and >10 MUg/ml), and nine against P. falciparum (IC50: 0.96 MUg/ml to 4.69 MUg/ml). Selectivity indices (SI) calculated for the most active extracts ranged from <1.00 to 94.24. However, the B. adoensis leaf dichloromethane extract (a) was equipotent (IC50 = 3.3 MUg/ml) against L. donovani and L6 cells respectively, indicating non-specific selection. Trypanosome and Plasmodium parasites were comparatively more sensitive to the test extracts. CONCLUSIONS: The benefits achieved from the seven tested plant species as traditional ethnomedicinal and ethnoveterinary therapies or in zoopharmacognosy against infections and conditions of animals in the wild are strongly supported by results of this study. The synergy of plant extracts, so achieved by concerted actions of the ligands, produces adequate perturbation of targets in the four parasite genera, resulting in the strong potencies exhibited by low IC50 values. The total inhibitory effect, achieved as a sum of perturbations contributed by each participating compound in the extract, minimises toxic effects of the compounds as seen in the high SI's obtained with some extracts. Those extracts demonstrating SI >= 4 form promising candidates for further cell-based and system pharmacology studies.

AB - Triclosan (TCS, 5-chloro-2-(2,4-dichlorophenoxy) phenol) is becoming a major surface waters pollutant worldwide at concentrations ranging from ng L-1 to MUg L 1. Up to now, the adverse effects on aquatic organisms have been investigated at concentrations higher than the environmental ones, and the pathways underlying the observed toxicity are still not completely understood. Therefore, the aim of this study was to investigate the toxic effects of TCS at environmental concentrations on zebrafish embryos up to 120 hours post fertilization (hpf). The experimental design was planned considering both the quantity and the exposure time for the effects on the embryos, exposing them to two different concentrations (0.1 MUg L-1, 1 MUg L-1) of TCS, for 24 h (from 96 to 120 hpf) and for 120 h (from 0 to 120 hpf). A suite of biomarkers was applied to measure the induction of embryos defence system, the possible increase of oxidative stress and the DNA damage. We measured the activity of glutathione-S-transferase (GST), P-glycoprotein efflux and ethoxyresorufin-o-deethylase (EROD), the level of ROS, the oxidative damage through the Protein Carbonyl Content (PCC) and the activity of antioxidant enzymes. The genetic damage was evaluated through DNA Diffusion Assay, Micronucleus test (MN test), and Comet test. The results showed a clear response of embryos defence mechanism, through the induction of P-gp efflux functionality and the activity of detoxifying/antioxidant enzymes, preventing the onset of oxidative damage. Moreover, the significant increase of cell necrosis highlighted a strong cytotoxic potential for TCS. The overall results obtained with environmental concentrations and both exposure time, underline the critical risk associated to the presence of TCS in the aquatic environment. PMID- 30273737 TI - A fast and reliable protocol for activation of porcine oocytes. AB - Oocyte activation is physiologically triggered by the sperm during fertilization, however, production of porcine embryos by somatic cell nuclear transfer (SCNT), intracytoplasmic sperm injection (ICSI) or parthenogenetic activation (PA) requires artificial oocyte activation. Although effective protocols for artificial oocyte activation have been developed, current protocols require long exposures to non-specific inhibitors, which do not mimic the physiological process and may have detrimental consequences for embryo development. This study attempted to mimic the physiological activation events induced by fertilization, through the manipulation of Ca2+ and Zn2+ levels, and protein kinase C (PKC) as well as cyclin dependent kinase 1 (CDK1) activities, with the aim of developing an improved protocol for activation of porcine oocytes. In the first experiment, matured oocytes were exposed to ionomycin (Ion) for 5 min, and then treated with a specific CDK1 inhibitor (RO-3306) and/or PKC activator (OAG) for different time intervals. The highest rate of pronuclear (PN) formation (58.8%) was obtained when oocytes were treated with PKCa + CDK1i for 4 h. Second, PN formation and embryo development were evaluated in oocytes exposed for different times to a Zn2+ chelator (TPEN) following Ion treatment. This revealed that 15 min was the minimal exposure time to TPEN required to maximise oocyte activation and embryo development. Next, we observed that treatment with PKCa + CDK1i for 4 h after TPEN for 15 min decreased embryo development compared to TPEN alone. Lastly, we compared the efficiency of the Ion (5 min) plus TPEN (15 min) protocol (IT-20) with a control protocol used in our laboratory (CT-245) for production of PA, SCNT and ICSI embryos. In PA embryos, IT-20 resulted in higher cleavage (72% vs 49.2%) and blastocyst from cleaved embryos (65.5% vs 46.2%) compared to CT-245. In ICSI embryos, higher PN rates were obtained with the IT-20 protocol compared with CT-245 and the non-activated (N-A) group. Moreover, the two protocols were equally efficient for activation of SCNT embryos. Based on these findings, we propose that IT-20 is a fast and effective protocol for activation of porcine oocytes. PMID- 30273739 TI - Effect of the hematopoietic growth factors erythropoietin and kit ligand on bovine oocyte in vitro maturation and developmental competence. AB - The overall aim of this work was to study the influence of the hematopoietic growth factors erythropoietin (EPO) and kit ligand (KITL) during bovine oocyte in vitro maturation (IVM). The effect of adding different concentrations of EPO or KITL to maturation medium was evaluated analyzing oocyte nuclear maturation, cumulus cells apoptosis, embryo cleavage, reactive oxygen species (ROS) production in matured oocytes and cleaved embryos and the developmental competence to the blastocyst stage. No significant differences were observed in the percentage of oocytes that completed nuclear maturation among treatments, but the percentages of cleaved embryos and blastocysts obtained increased. With the addition of both hematopoietic growth factors the percentage of cumulus cells undergoing apoptosis decreased, the number of blastomeres per cleaved embryo was larger and ROS production per cleaved embryo increased. In conclusion, although the addition of EPO and KITL hematopoietic growth factors during bovine oocyte IVM had no impact on nuclear maturation, it had a positive effect on oocyte cytoplasmic maturation and developmental competence. PMID- 30273740 TI - Hydration-induced nano- to micro-scale self-recovery of the tooth enamel of the giant panda. AB - The tooth enamel of vertebrates comprises a hyper-mineralized bioceramic, but is distinguished by an exceptional durability to resist impact and wear throughout the lifetime of organisms; however, enamels exhibit a low resistance to the initiation of large-scale cracks comparable to that of geological minerals based on fracture mechanics. Here we reveal that the tooth enamel, specifically from the giant panda, is capable of developing durability through counteracting the early stage of damage by partially recovering its innate geometry and structure at nano- to micro- length-scales autonomously. Such an attribute results essentially from the unique architecture of tooth enamel, specifically the vertical alignment of nano-scale mineral fibers and micro-scale prisms within a water-responsive organic-rich matrix, and can lead to a decrease in the dimension of indent damage in enamel introduced by indentation. Hydration plays an effective role in promoting the recovery process and improving the indentation fracture toughness of enamel (by ~73%), at a minor cost of micro-hardness (by ~5%), as compared to the dehydrated state. The nano-scale mechanisms that are responsible for the recovery deformation, specifically the reorientation and rearrangement of mineral fragments and the inter- and intra-prismatic sliding between constituents that are closely related to the viscoelasticity of organic matrix, are examined and analyzed with respect to the structure of tooth enamel. Our study sheds new light on the strategies underlying Nature's design of durable ceramics which could be translated into man-made systems in developing high performance ceramic materials. STATEMENT OF SIGNIFICANCE: Tooth enamel plays a critical role in the function of teeth by providing a hard surface layer to resist wear/impact throughout the lifetime of organisms; however, such enamel exhibits a remarkably low resistance to the initiation of large-scale cracks, of hundreds of micrometers or more, comparable to that of geological minerals. Here we reveal that tooth enamel, specifically that of the giant panda, is capable of partially recovering its geometry and structure to counteract the early stages of damage at nano- to micro-scale dimensions autonomously. Such an attribute results essentially from the architecture of enamel but is markedly enhanced by hydration. Our work discerns a series of mechanisms that lead to the deformation and recovery of enamel and identifies a unique source of durability in the enamel to accomplish this function. The ingenious design of tooth enamel may inspire the development of new durable ceramic materials in man-made systems. PMID- 30273738 TI - The effects of crocetin supplementation on the blastocyst outcome, transcriptomic and metabolic profile of in vitro produced bovine embryos. AB - The earliest stages of embryo development are deeply influenced by reactive oxygen species (ROS), byproducts of the mitochondrial oxygen metabolism that play a key role as messengers in normal cell signal transduction and cell cycling. Despite its positive roles, the imbalance caused by the excess of ROS and an inefficient antioxidant system leads to oxidative stress, with negative consequences to the cell such as DNA damage, metabolic changes, mitochondrial stress and cell death. In the present work, crocetin - a natural antioxidant - was added to the culture media of bovine embryos to evaluate the efficiency of its antioxidant capability during embryo culture. Oocytes were in vitro matured (IVM) and fertilized according to standard protocols. Embryos were cultured at 38.5 degrees C under humidified air with 5% CO2, 7% O2, and 90% N2 in Synthetic Oviduct Fluid (SOF) medium supplemented with amino acids and either 5% of FBS (SOFaa) (control group) or SOFaa supplemented with 1 MUM crocetin (crocetin group). After 5 days from the beginning of in vitro culture (IVC) (day 5 - D5), embryos were transferred to individual drops of culture media. At day 7 (D7), embryos were assessed by means of blastocyst rates, morphophysiological analyzes (total cell number, ROS and mitochondrial activity levels), transcript quantitation of 47 genes and metabolomic evaluation of the culture media by Raman spectroscopy. In the crocetin group blastocyst rates were higher and embryos had increased total cell number and decreased intracellular levels of ROS. These embryos also had upregulation of genes related with response to stress and lipid metabolism (ATF4, BAX, FOXO3, GADD45A, GPX1, GPX4, HSF1, SOD2, ACACA, SREBF1 and SREBF2). Raman spectroscopy corroborated these results indicating more active lipid and amino acid production in this group. The absence of crocetin in the culture media resulted in higher ROS level, as well as up regulation of genes related to DNA damage, stress response and energy metabolism (MORF4L2, SOD1, TXN, PFKP, PGK1 and PPARGC1A). In conclusion, crocetin supplementation during culture protects embryos from oxidative stress and influences the adaptive response to stress conditions, leading to an increase in both blastocyst yield and quality, as well as changes in transcriptomic and metabolic profile of in vitro produced bovine embryos. PMID- 30273741 TI - Mechanically stimulated osteochondral organ culture for evaluation of biomaterials in cartilage repair studies. AB - Surgical procedures such as microfracture or autologous chondrocyte implantation have been used to treat articular cartilage lesions; however, repair often fails in terms of matrix organization and mechanical behaviour. Advanced biomaterials and tissue engineered constructs have been developed to improve cartilage repair; nevertheless, their clinical translation has been hampered by the lack of reliable in vitro models suitable for pre-clinical screening of new implants and compounds. In this study, an osteochondral defect model in a bioreactor that mimics the multi-axial motion of an articulating joint, was developed. Osteochondral explants were obtained from bovine stifle joints, and cartilage defects of 4 mm diameter were created. The explants were used as an interface against a ceramic ball applying dynamic compressive and shear loading. Osteochondral defects were filled with chondrocytes-seeded fibrin-polyurethane constructs and subjected to mechanical stimulation. Cartilage viability, proteoglycan accumulation and gene expression of seeded chondrocytes were compared to free swelling controls. Cells within both cartilage and bone remained viable throughout the 10-day culture period. Loading did not wear the cartilage, as indicated by histological evaluation and glycosaminoglycan release. The gene expression of seeded chondrocytes indicated a chondrogenic response to the mechanical stimulation. Proteoglycan 4 and cartilage oligomeric matrix protein were markedly increased, while mRNA ratios of collagen type II to type I and aggrecan to versican were also enhanced. This mechanically stimulated osteochondral defect culture model provides a viable microenvironment and will be a useful pre-clinical tool to screen new biomaterials and biological regenerative therapies under relevant complex mechanical stimuli. STATEMENT OF SIGNIFICANCE: Articular cartilage lesions have a poor healing capacity and reflect one of the most challenging problems in orthopedic clinical practice. The aim of current research is to develop a testing system to assess biomaterials for implants, that can permanently replace damaged cartilage with the original hyaline structure and can withstand the mechanical forces long term. Here, we present an osteochondral ex vivo culture model within a cartilage bioreactor, which mimics the complex motion of an articulating joint in vivo. The implementation of mechanical forces is essential for pre-clinical testing of novel technologies in the field of cartilage repair, biomaterial engineering and regenerative medicine. Our model provides a unique opportunity to investigate healing of articular cartilage defects in a physiological joint-like environment. PMID- 30273742 TI - Mesoporous bioactive glasses: Promising platforms for antibacterial strategies. AB - The control of bacterial infections is of particular importance in the field of tissue engineering. Recently, much attention has been addressed toward the use of mesoporous bioactive glasses (MBGs) for antibacterial strategies, primarily because of their capability of acting as carriers for the local release of antimicrobial agents. The incorporation of antibacterial metallic ions including silver (Ag+), zinc (Zn2+), copper (Cu+ and Cu2+), cerium (Ce3+ and Ce4+), and gallium (Ga3+) cations into the MBG structure and their controlled release is proposed as one of the most attractive strategies for inhibiting bacterial growth and reproduction. Moreover, the possibility of loading and delivering various antibacterial biomolecules (e.g., antibiotics) through the porous structure of MBGs makes them as ideal candidates for antibacterial applications. In this review, we aim to present a comprehensive evaluation of MBG potential regarding antibacterial activities. For this purpose, different types of antibacterial ion doped and drug-loaded MBGs are introduced and discussed in the light of existing knowledge, along with the significant challenges ahead. STATEMENT OF SIGNIFICANCE: Prevention and treatment of infections is one of the today's greatest challenges in medical sciences, also considering the well-known issues related to increased bacterial resistance to antibiotics. The advent of mesoporous glasses led to the birth of a new class of multifunctional biomaterials acting as bioactive platforms for the local release of organic or inorganic agents eliciting an antimicrobial effect. This reviews summarizes the state of the art of MBGs in this field, highlighting the latest evolutions and the specific role played by metallic antimicrobial ions that can be incorporated in the glass composition and then properly released. Perspective for tissue engineering applications are also discussed to provide an up-to-date contribution that is useful to both experienced scientists and early-stage researchers. PMID- 30273743 TI - Graphene oxide induces p62/SQSTM-dependent apoptosis through the impairment of autophagic flux and lysosomal dysfunction in PC12 cells. AB - Graphene oxide (GO), as a two-dimensional carbon nanosheet, has been extensively studied for potential biomedical applications due to its notable properties. Although a growing number of studies have investigated the adverse effects of GO nanosheets, the available toxicity data concerning GO's effect on the neuronal cells remain highly limited. In this work, we systematically investigated the toxic responses of commercially available GO on a rat pheochromocytoma-derived PC12 cell line, which was an ideal in vitro model to study the neurotoxicity of GO. GO exerted a significant toxic effect on PC12 cells in a dose- and time dependent manner. GO treatments under doses of 40, 50, and 60 MUg/mL triggered an autophagic response and the blockade of autophagic flux via disrupting lysosome degradation capability. Caspase 9-mediated apoptosis was also observed in GO treated cells. Moreover, GO-induced apoptosis was relevant to the aberrant accumulation of autophagy substrate p62/SQSTM. Inhibitionofthe accumulation of autophagic substrate alleviated GO-caused apoptotic cell death. Our findings raise a concern for the putative biomedical applications of GO in the form of diagnostic and therapeutic tools, where its systematic biocompatibility should be thoroughly explored. STATEMENT OF SIGNIFICANCE: Graphene oxide (GO) has attracted considerable interests in biomedical fields, which also resulted in numerous safety risks to human bodies. It is urgently required to establish a paradigm for accurately evaluating their adverse effects in biological systems. This study thoroughly explored the neurotoxicity of GO in PC12 cells. We found GO triggered an increased autophagic response and the impairment of autophagic flux, which was functionally involved in cell apoptosis. Inhibitionofexcessive accumulation of autophagic cargo attenuated apoptotic cell death. Our findings highlight deep considerations on the regulation mechanism of autophagy-lysosomes-apotosis-axis, which will contribute to a better understanding of the neurotoxicity of graphene family nanomaterials, and provide a new insight in the treatment of cancer cells at nanoscale levels. PMID- 30273744 TI - Correlating diameter, mechanical and structural properties of poly(l-lactide) fibres from needleless electrospinning. AB - The development and application of nanofibres requires a thorough understanding of the mechanical properties on a single fibre level including respective modelling tools for precise fibre analysis. This work presents a mechanical and morphological study of poly-l-lactide nanofibres developed by needleless electrospinning. Atomic force microscopy (AFM) and micromechanical testing (MMT) were used to characterise the mechanical response of the fibres within a diameter range of 200-1400 nm. Young's moduli E determined by means of both methods are in sound agreement and show a strong increase for thinner fibres below a critical diameter of 800 nm. Similar increasing trends for yield stress and hardening modulus were measured by MMT. Finite element analyses show that the common practice of modelling three-point bending tests with either double supported or double clamped beams is prone to significant bias in the determined elastic properties, and that the latter is a good approximation only for small diameters. Therefore, an analytical formula based on intermediate boundary conditions is proposed that is valid for the whole tested range of fibre diameters, providing a consistently low error in axial Young's modulus below 10%. The analysis of fibre morphology by differential scanning calorimetry and 2D wide-angle X-ray scattering revealed increasing polymer chains alignment in the amorphous phase and higher crystallinity of fibres for decreasing diameter. The combination of these observations with the mechanical characterisation suggests a linear relationship between Young's modulus and both crystallinity and molecular orientation in the amorphous phase. STATEMENT OF SIGNIFICANCE: Fibrous membranes have rapidly growing use in various applications, each of which comes with specific property requirements. However, the development and production of nanofibre membranes with dedicated mechanical properties is challenging, in particular with techniques suitable for industrial scales such as needleless electrospinning. It is therefore a key step to understand the mechanical and structural characteristics of single nanofibres developed in this process, and to this end, the present work presents changes of internal fibre structure and mechanical properties with diameter, based on dedicated models. Special attention was given to the commonly used models for analyzing Young's modulus of single nanofibers in three-point bending tests, which are shown to be prone to large errors, and an improved robust approach is proposed. PMID- 30273745 TI - Antimicrobial activity of commercial calcium phosphate based materials functionalized with vanillin. AB - Infections represent one of the most frequent causes of arthroplasty revision. Thus, design of new antimicrobial scaffolds to reduce implant rejections, bone infections and associated medical costs is highly desired. In recent years, essential oil components (EOCs) have merged as compounds with significant antimicrobial activity that can be attached to specific surfaces to enhance and prolong their antimicrobial effect. Herein calcium phosphate CaP regenerative materials have been coated with a vanillin derivative to combine its original bone regeneration properties with antimicrobial action of EOCs. Materials in form of microparticles and blocks were prepared and fully characterized. Clonogenic viability tests demonstrated that low concentrations of material (10 mg.mL-1) resulted effective to kill 100% of E. coli DH5alpha bacteria. Additionally, vanillin containing scaffolds did not display any toxic effect over cells, yet they preserve the ability to express alkaline phosphatase (ALPL), collagen type 1, chain alpha1 (COL1A1) and bone gamma-carboxyglutamic acid-containing protein or osteocalcin (BGLAP), which are genes typically expressed by osteoblasts. These results demonstrate that commercially available scaffolds can be functionalized with EOCs, achieving antimicrobial activity and open up a new approach for the treatment and prevention of infection. STATEMENT OF SIGNIFICANCE: During the last years, the interest in bone regenerative materials with antibiotic properties has increased, since prosthesis infection is one of the most usual complications in implant surgery. In this work, we report a hybrid system composed by a calcium phosphate material (powders and scaffolds) functionalized with the derivative of an essential oil component (EOC). Our purpose was to provide the calcium phosphate material with antimicrobial activity without harming its bone regenerative capability. The obtained results were encouraging, which opens up the possibility of developing new modified materials for the prevention and treatment of bone infection. PMID- 30273746 TI - Bactericidal effects of nanopatterns: A systematic review. AB - : We systematically reviewed the currently available evidence on how the design parameters of surface nanopatterns (e.g. height, diameter, and interspacing) relate to their bactericidal behavior. The systematic search of the literature resulted in 46 studies that satisfied the inclusion criteria of examining the bactericidal behavior of nanopatterns with known design parameters in absence of antibacterial agents. Twelve of the included studies also assessed the cytocompatibility of the nanopatterns. Natural and synthetic nanopatterns with a wide range of design parameters were reported in the included studies to exhibit bactericidal behavior. However, most design parameters were in the following ranges: heights of 100-1000 nm, diameters of 10-300 nm, and interspacings of <500 nm. The most commonly used type of nanopatterns were nanopillars, which could kill bacteria in the following range of design parameters: heights of 100 900 nm, diameters of 20-207 nm, and interspacings of 9-380 nm. The vast majority of the cytocompatibility studies (11 out of 12) showed no adverse effects of bactericidal nanopatterns with the only exception being nanopatterns with extremely high aspect ratios. The paper concludes with a discussion on the evidence available in the literature regarding the killing mechanisms of nanopatterns and the effects of other parameters including surface affinity of bacteria, cell size, and extracellular polymeric substance (EPS) on the killing efficiency. STATEMENT OF SIGNIFICANCE: The use of nanopatterns to kill bacteria without the need for antibiotics represents a rapidly growing area of research. However, the optimum design parameters to maximize the bactericidal behavior of such physical features need to be fully identified. The present manuscript provides a systematic review of the bactericidal nanopatterned surfaces. Identifying the effective range of dimensions in terms of height, diameter, and interspacings, as well as covering their impact on mammalian cells, has enabled a comprehensive discussion including the bactericidal mechanisms and the factors controlling the bactericidal efficiency. Overall, this review helps the readers have a better understanding of the state-of-the-art in the design of bactericidal nanopatterns, serving as a design guideline and contributing to the design of future experimental studies. PMID- 30273747 TI - Peroxidase-immobilized porous silica particles for in situ formation of peroxidase-free hydrogels with attenuated immune responses. AB - Enzymatic crosslinking chemistry using horseradish peroxidase (HRP) has been widely utilized as an effective approach to fabricating injectable hydrogels with high efficiency under mild reaction conditions. However, their clinical applications are limited by the immunogenicity of the plant-derived enzyme. Herein we report the design, synthesis and characterization of HRP-immobilized porous silica particles (HRP-particles) and their use for in situ formation of HRP-free hydrogels. HRP was immobilized on aminopropyl-modified porous silica particles of 70-140 um in diameter via poly(ethylene glycol) spacers of different molecular weights by reductive amination reaction. Two different HRP-free hydrogels based on dextran-tyramine and gelatin-hydroxyphenylpropionic acid (GHPA) conjugates were produced by passing a solution containing the conjugates and H2O2 through a syringe packed with HRP-particles. The storage modulus and gelation rate of both hydrogels were tunable by varying the contact time between the polymer solution and HRP-particles. Our in vitro study revealed that HRP-free GHPA hydrogel was less stimulatory to activated mouse macrophages than HRP containing GHPA hydrogel with the same stiffness. Furthermore, HRP-free GHPA hydrogel exhibited remarkably lower levels of local and systemic inflammation than HRP-containing one upon subcutaneous injection in immunocompetent C57BL/6J mice. The attenuated immunogenicity of HRP-free GHPA hydrogels makes them an attractive platform for tissue engineering applications. STATEMENT OF SIGNIFICANCE: The immunogenicity of HRP is a significant issue for clinical application of HRP-catalyzed in situ forming hydrogels. HRP-particles are developed to overcome the safety concerns by fabricating HRP-free hydrogels. The porosity of silica particles and molecular weight of poly(ethylene glycol) spacers are discovered as important factors determining the catalytic ability of HRP-particles to induce the in situ crosslinking of polymer-phenol conjugates. Although several articles speculate the potential of HRP to trigger immune responses when administered as a part of hydrogel formulation, no literature has attempted to investigate the immunogenicity of HRP-containing hydrogels in comparison with HRP-free hydrogels. Our findings suggest that the immunogenicity issue should be carefully considered before clinical translation of HRP containing hydrogels. PMID- 30273748 TI - The inflammasome in host response to biomaterials: Bridging inflammation and tissue regeneration. AB - : The development of new biomaterials to be used in tissue engineering applications is creating new solutions for a range of healthcare problems. The trend in biomaterials research has shifted from biocompatible "immune-evasive" biomaterials to "immune-interactive" materials that modulate the inflammatory response supporting implant integration as well as improving healing and tissue regeneration. Inflammasomes are large intracellular multiprotein complexes that are key players in host defence during innate immune responses and assemble after recognition of pathogens or danger signals. The process of biomaterial implantation causes injury to tissues that will consequently release danger signals that could be sensed by the inflammasome. There are increasing evidences that the inflammasome has a role in several inflammatory processes, from pathogen clearance to chronic inflammation or tissue repair. Thus, modulation of the inflammasome activity appears as an important target in the development of effective approaches in regenerative medicine. In this review, we discuss the main points of the current understanding on the host response to implanted biomaterials and how the paradigm of "immune-evasive" biomaterials has shifted over the last years; the significance of the inflammasome in the inflammatory response to biomaterials; and the growing idea that the immune system is of key importance in an effective tissue repair and regeneration. STATEMENT OF SIGNIFICANCE: We herein discuss the main points of the current understanding on the host response to implanted biomaterials and how the paradigm of "immune evasive" biomaterials has shifted to "immune-interactive" over the last years; the significance of the inflammasome in the inflammatory response to biomaterials; and the growing idea that the immune system is of key importance in an effective tissue repair and regeneration, supporting the emerging concept of Regenerative Immunology. The inflammasome is a recent and central concept in immunology research. Since the beginning of this century the inflammasome is viewed as key platform of the innate immune response. We believe that, successful modulation of the inflammasome activity will become a milestone in the fields of tissue engineering and regenerative medicine. PMID- 30273749 TI - Side effects-avoided theranostics achieved by biodegradable magnetic silica sealed mesoporous polymer-drug with ultralow leakage. AB - The development of drug delivery vehicles without side effects to normal physiological tissues represents an urgent challenge for safety and effective nanomedicine. Herein, a multifunctional drug delivery vehicle with ultralow leakage was presented, containing an ordered mesoporous resin as a polymer core and homogeneous Fe nanodots-doped silica as the biodegradable shell. In this core shell structure, the Fe-doped silica shell acts as a compact inorganic cap to seal doxorubicin into the mesoporous polymer cores, but also serves as a superparamagnetic agent for magnetic targeting and magnetic resonance imaging (MRI). Importantly, the caps can be opened via Fe extraction-induced degradation to slowly release the loaded drug under the acidic tumor environment, while achieving ultralow drug leakage under normal in vivo blood circulation (physiological environment). This unique core-shell nanospheres with ultralow drug leakage were demonstrated to achieve side effects-avoided targeting chemotherapy guided by MRI with improved therapeutic outcomes, which showing great potential for efficient cancer theranostics.

PMID- 30273753 TI - Maintaining performance in searching dogs: Evidence from a rat model that training to detect a second (irrelevant) stimulus can maintain search and detection responding. AB - Scent-detecting dogs perform a sequence, or chain, of behaviors that, at minimum, includes searching followed by a detection behavior that signals the presence of a target stimulus to the handler. However, when working, dogs often engage in prolonged periods of searching without encountering a target. It is therefore important for trainers to use methods that promote persistent search behavior and target detection accuracy. Laboratory models can provide insights to the important variables that influence search persistence and accuracy. The present experiments examined a rat model of detection dog behavior. Two experiments assessed the use of practice with a single target stimulus to maintain search and detection of another previously-trained target. In Experiment 1, after learning a search->detection chain with two auditory targets, rats received either brief or extended training with only one of the targets before being tested for detection of both targets in extinction. The results suggest that single-target training strengthened the ability of the other target to control the detection behavior. Experiment 2 found that even infrequent target encounters were still effective at maintaining detection behavior to the other trained target. Importantly, the treatment was effective when the target stimuli were from different sensory modalities. Overall, the results support the utility of the rat model of search dog behavior for evaluating novel training methods. We suggest several useful procedures for enhancing search persistence and accuracy in detection dogs that can be implemented in training protocols. PMID- 30273754 TI - Predator avoidance training of the endangered lizard from El Hierro (Canary Islands): A new management strategy before reintroduction into the wild. AB - Animals raised in captivity during several generations may not express appropriate antipredator behaviour when reintroduced into the wild. Here we present the results of experiments to enhance behavioural responses to predators in adult males of the endangered lizard Gallotia simonyi (El Hierro, Canary Islands). Individuals were subjected to a training procedure (control, pre training, training and post-training phases) using stuffed specimens of a kestrel and a cat as predators. We filmed all trials and compared relative durations of the more common behaviour patterns shown by lizards, both among experimental phases and before and after presentation of the stuffed predator. Locomotion and Basking were significantly reduced in the training and post-training trials and also after stimulus presentation, suggesting that the training protocol induced lizard avoidance over both predator models. To our knowledge, this is the first time lizards have been trained to show antipredator avoidance and our results provide the basis for a new management strategy that could be useful for reintroduction of captive-bred individuals of endangered species. PMID- 30273755 TI - Preference in female laboratory mice is influenced by social experience. AB - Mice must perceive and interpret the signals they are presented with to evaluate potential mates, and should show a preference for high quality conspecifics. The present experiment was designed to investigate preference for acoustic, olfactory, and acoustic + olfactory signals in laboratory mice. Eighteen female CBA/CaJ mice, socially housed or isolated, were tested to evaluate preference for signals produced by males. Social experience influenced female preference for male USV playback and soiled bedding. Female mice who had experience with males showed a stronger preference for olfactory signals, whereas female mice with experience only with other females preferred USV playback. Isolated mice showed a greater preference for signals of different modalities presented together than socially experienced mice. This preference may have occurred because of increased motivation to make social contact. The findings of this experiment illustrate that social experience could play a role in mate choice. PMID- 30273756 TI - High extinction rates and non-adaptive radiation explains patterns of low diversity and extreme morphological disparity in North American blister beetles (Coleoptera, Meloidae). AB - Untangling the relationship between morphological evolution and lineage diversification is key to explain global patterns of phenotypic disparity across the Tree of Life. Few studies have examined the relationship between high morphological disparity and extinction. In this study, we infer phylogenetic relationships and lineage divergence times within Eupomphini (Meloidae), a tribe of blister beetles endemic to the arid zone of North America, which exhibits a puzzling pattern of very low species richness but wild variation in morphological diversity across extant taxa. Using Bayesian and maximum likelihood inference, we estimate diversification and phenotypic evolutionary rates and infer the time and magnitude of extinction rate shifts and mass extinction events. Our results suggest that Eupomphini underwent an event of ancient radiation coupled with rapid morphological change, possibly linked to the loss of the evolutionary constraint in the elytral shape. A high extinction background associated to the Miocene-Pliocene transition decimated the diversity within each major clade, resulting in the species-poor genera observed today. Our study supports a connection between high extinction rates and patterns of decoupled phenotypic evolution and lineage diversification, and the possibility of a radiation in the absence of ecological release. PMID- 30273757 TI - Genomic insights of Vibrio harveyi RT-6 strain, from infected "Whiteleg shrimp" (Litopenaeus vannamei) using Illumina platform. AB - The pathogenicity of "Vibriosis" in shrimps imposes prominent menace to the sustainable growth of mariculture economy. Often the disease outbreak is associated speciously with Vibrio harveyi and its closely related species. The present study investigated the complete genome of the strain V. harveyi RT-6 to explore the molecular mechanism of pathogenesis. The genome of V. harveyi possesses a single chromosome of 6,374,398 bp in size, G + C content (44.7%) and 5730 protein coding genes. The reads of 1.3 Gb were retained from Illumina Hiseq 2500 sequencing method, assembled into 5912 predicted genes, 114 tRNAs genes, and 11 rRNAs genes. Unigenes were annotated by matching against Clusters of Orthologous Groups of proteins (COG)-5730, Gene ontology (GO)-1088, and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases-3401. Furthermore, 13 insertion sequences-(IS), virulence factors and prophage regions were also identified. A total of 94 pathogenic genes and 36 virulence factor genes were mainly identified using Virulence Factors Database (VFDB). Out of the 36 virulence factors, 23 genes responsible for encoding flagella-based motility protein were exclusively predicted to take part in pathogenic mechanism. The Whole Genome Sequencing (WGS) of the strain RT-6 (accession number: SRR5410471) highlighted the underlying genes and specifically accountable functional genes that were responsible for pathogenic infections in shrimps.

AB - Proton and deuteron beams (15.3 and 6.8 MeV, respectively) extracted from the PETtrace medical cyclotron at the Radiopharmaceuticals Production and Research Centre in the University of Warsaw, Heavy Ion Laboratory, 28 MeV protons from the C30 cyclotron at the National Centre for Nuclear Research, Swierk, near Warsaw and 33 MeV protons from the ARRONAX accelerator, Nantes were used to produce and investigate the medically interesting Sc radioisotopes. Both natural and isotopically enriched CaCO3 and TiO2 targets were used (42Ca, 43Ca, 44Ca, 48Ca, 48Ti). The production efficiency and isotopic purity were determined and are reported here for the highest commercially available enrichments of the target material. The Thick Target Yield, Activities at the End of Bombardment (EOB) and the relative activities of produced impurities at EOB are reported for 43Sc, 44gSc, 44mSc and 47Sc produced with particle energies below 33 MeV.

AB - Erbium-activated lithium niobate; 1, 2, and 4 mol% (LN-1, LN-2 and LN-4 respectively) were synthesized by solid-state method and their thermoluminescent (TL) properties were analyzed. The glow curve of LN-4 showed a maximum at 177 degrees C and its linear dose-response interval ranged from 50 to 350 Gy. Its TL intensity was two orders of magnitude greater compared to those of pure lithium niobate (LN), LN-1 and LN-2. We conclude that LN-4 is an interesting material for TL dosimetry applications.

AB - We report nearly continuous beta-decay-rate measurements of Na-22, Cl-36, Co-60, Sr-90, and Cs-137 over a period of 2.7 years using four Geiger-Muller tubes. We carefully control the ambient pressure and temperature for the detectors, sources, and electronics in order to minimize environmentally-dependent systematic drifts in the measurement chains. We show that the amplitudes of an annual oscillation in the decay rates are consistent with zero to within 0.004%. PMID- 30273761 TI - Uncertainty evaluation in gamma spectrometric measurements: Uncertainty propagation versus Monte Carlo simulation. AB - Calculation and reporting of combined measurement uncertainties are important in decision making processes, and a more proper uncertainty estimation can reduce the risk and/or the cost associated with decisions for example after radiological incidents and in free release measurements of radioactive waste. However, sound decisions demand a sound uncertainty estimation. In this work we present the possible consequences when uncertainty propagation is applied to gamma-ray spectrometry measurements involving assumed probability density functions for an efficiency transfer having different metrological quality by comparison with Monte Carlo simulations. PMID- 30273763 TI - Internalization capabilities of gold-198 nanoparticles: Comparative evaluation of effects of chitosan agent on cellular uptake into MCF-7. AB - In this study, internalization of positively charged chitosan-coated nanoparticles (198AuNPs@chitosan) on MCF-7 cells was investigated by gamma-ray spectroscopy and then statistically compared to that of 198Au and negatively charged citrate-stabilized nanoparticles (198AuNPs). Sub-50 nm 198AuNPs@chitosan had a higher internalization compared to 198Au and 198AuNPs (p < 0.05). More cellular uptake of 198AuNP@chitosan means a higher dose of radioactivity to the tumor cells which, in turn, more effective treatment of the cancer. PMID- 30273762 TI - A method for determining density based on gamma ray and fast neutron detection using a Cs2LiYCl6 detector in neutron-gamma density logging. AB - With the increasing demand for radioisotope-free operations, pulsed neutron-gamma density (NGD) has become increasingly important for logging-while-drilling (LWD) development. However, current NGD tools, adopting the multiple-detector array design, are not conducive to the simplification of instrument design and measurement system. To break obstacles, based on the fast neutron-gamma coupled theory, a new density measurement method was proposed. Further, combined with the neutron-gamma simultaneous detection characteristics of the Cs2LiYCl6 (CLYC) detector, an NGD measurement system consisting of a D-T source and one CLYC detector was used. Results show that the new method is capable of determining formation density using a single CLYC detector, which can not only avoid complex instrument systems but also improve density sensitivity. Moreover, the applicability of the new density method was well verified by Monte Carlo simulation. Additionally, the method was successfully applied in a simulated well, and density results are in good agreement with the benchmarked formations. The research provides theoretical guidance for NGD instrument design. PMID- 30273764 TI - Radiation safety analysis for the A-BNCT facility in Korea. AB - A Proton Accelerator based Boron Neutron Capture Therapy (A-BNCT) facility is under development in Korea. Neutron beams for treatment are produced from a beryllium (Be) target and an 8 mA, 10 MeV proton beam. The purpose of the research is a radiation shielding analysis and an activation analysis for the facility design satisfying the radiation safety requirements as well as obtaining an operating license for the radiation facility according to a domestic nuclear commissioning procedure. The radiation shielding analysis was performed using the MCNPX computational particle transport code. The radiation source terms in the facility were evaluated and utilized in the shielding calculations. The minimum concrete thickness satisfying the designated dose rate of 5 MUSv/h for the worker's area and 0.25 MUSv/h for the public area were estimated and applied to the design. For an assessment of the radiation safety inside the facility, the dose rates were evaluated at several positions, such as behind the shielding door, around the primary barriers near the radiation sources, and in the penetrations of the ducts. The dose rate distribution was mapped for verification of the radiation safety for the entire facility. An activation analysis was carried out for the concrete walls, air, target assembly, beryllium target, and cooling water using FISPACT-2010 code. Concentrations of the activation products and dose rate induced by the radionuclides after shutdown were evaluated for the purpose of safe operation of the facility. The results were reviewed with the radiation safety regulations in Korea. As a result, it was proved that the final facility design satisfies the safety requirements. PMID- 30273765 TI - Foreign language reduces the longevity of the repetition-based truth effect. AB - Recent evidence suggests that judgment biases may diminish when a problem is presented in a foreign language. This foreign-language effect has primarily been examined with emotional materials such as risky-choice problems and moral dilemmas. In two experiments, we investigated the effect of foreign-language processing on an emotionally neutral judgment bias: the repetition-based truth effect, the phenomenon that statement repetition enhances the perceived truth of statements. In Experiment 1, we found no evidence for the truth effect to be moderated by the language in which the statements were processed (native language: Hungarian; foreign language: English). In Experiment 2, in turn, we not only manipulated language (native language: German; foreign language: English), but also the retention interval between statement repetitions. Replicating the findings of Experiment 1, language did not moderate the truth effect for statements that were repeated within the same experimental session. However, after a two-week interval, the truth effect was significantly smaller in the foreign-language condition than in the native-language condition. Overall, our findings suggest a faster decay of semantic memory for foreign-language as compared to native-language statements. PMID- 30273766 TI - Positive impact of pulmonary vein isolation on biventricular pacing in nonresponders to cardiac resynchronization therapy. AB - BACKGROUND: Cardiac resynchronization therapy (CRT) is less effective in patients with atrial fibrillation (AF) because of impaired ventricular CRT capture. OBJECTIVE: We investigated the effects of catheter ablation in patients with AF and previous nonresponse to CRT. METHODS: Consecutive patients with AF and CRT nonresponse who underwent catheter ablation for AF were analyzed. CRT nonresponse was defined as one of the following: (1) reduced biventricular capture <95% due to rapidly conducted AF, (2) <1 point improvement in New York Heart Association (NYHA) class after CRT implantation, or (3) insufficient increase in left ventricular ejection fraction (LVEF; <=5%) after CRT implantation. RESULTS: Thirty-eight patients (8 women [21%]; mean age 68 +/- 10 years; LVEF 30% +/- 7%, biventricular capture 88.0% [25th, 75th percentile 75.3%, 98.5%]) underwent catheter ablation. One major and 1 minor complication occurred (1 lethal atrioesophageal fistula and 1 hemodynamically nonrelevant pericardial effusion). The Kaplan-Meier estimates for arrhythmia-free survival after single and multiple ablation procedures were 29% (95% confidence interval 16%-51%) and 67% (95% confidence interval 53%-86%) after 24 months. After a median follow-up of 817 days (25th, 75th percentile 179, 1741 days), biventricular capture and LVEF were significantly higher (median [25th, 75th percentile] 99% [96%, 99%], difference 8% [0.2%, 3.75%], P < .0001; mean 32.1% +/- 9.1%, difference 2.2% +/- 7.1%, P = .0225) and patients had a significantly lower functional NYHA class (28 of 37 patients with improvement of at least 1 point; P < .0001). CONCLUSION: Catheter ablation of AF significantly improves CRT response in patients with heart failure and concomitant AF in terms of increased biventricular capture and LVEF and improved functional NYHA class. PMID- 30273767 TI - Temporal relationships between esophageal injury type and progression in patients undergoing atrial fibrillation catheter ablation. AB - BACKGROUND: Currently, little is known about the onset, natural progression, and management of esophageal injuries after atrial fibrillation (AF) ablation. OBJECTIVES: We sought to provide a systematic review on esophageal injury after AF ablation and identify temporal relationships between various types of esophageal lesions, their progression, and clinical outcomes. METHODS: A comprehensive search of PubMed and Web of Science was conducted until September 21, 2017. All AF ablation patients who underwent upper gastrointestinal endoscopy within 1 week of the procedure were included. Patients with esophageal lesions were classified into 3 types by using our novel Kansas City classification: type 1: erythema; type 2a: superficial ulcers; type 2b: deep ulcers; type 3a: perforation without communication with the atria; and type 3b: perforation with atrioesophageal fistula. RESULTS: Thirty studies met our inclusion criteria. Of the 4473 patients, 3921 underwent upper gastrointestinal evaluation. The overall incidence of esophageal injuries was 15% (570). There were 206 type 1 lesions (36%), 222 type 2a lesions (39%), and 142 type 2b lesions (25%). Six of 142 type 2b lesions (4.2%) progressed further to type 3, of which, 5 were type 3a and 1 was type 3b. All type 1 and type 2a and most type 2b lesions resolved with conservative management. One type 3a and 1 type 3b lesions were fatal. CONCLUSION: Based on our classification, all type 1 and most type 2 lesions resolved with conservative management. A small percentage (4.2% [6 of 142]) of type 2b lesions progressed to perforation and/or fistula formation, and these patients need to be followed closely. PMID- 30273768 TI - Model-based learning and individual differences in depression: The moderating role of stress. AB - Inflexible decision-making has been proposed as a transdiagnostic risk factor for mood disorders. Evidence suggests that inflexible decision-making may emerge only when individuals are experiencing increased negative affect or stress. 151 participants completed symptom measures of depression and anxiety, followed by a two-stage decision-making task that distinguishes between habitual and goal directed choice. An experimental manipulation to induce stress was introduced halfway through the task. Individuals with higher depression levels became less model-based after the manipulation than those with lower depression levels. There was no relationship between trait anxiety and the impact of the manipulation on decision-making. Controlling for main effects of anxiety did not attenuate the association between depression and impact of stress. Anhedonia was associated with the impact of the manipulation on model-based decision-making. These results suggest that risk for depression is associated with reflexive decision-making, but these effects may only emerge under conditions of stress. PMID- 30273769 TI - Utilization of centrate for the outdoor production of marine microalgae at the pilot-scale in raceway photobioreactors. AB - In this study, the outdoor production of marine microalgae in raceway photobioreactors was investigated, modifying the centrate percentage in the culture medium (20, 30, 40 and 50%) and using two different dilution rates (0.2 day-1 and 0.3 day-1). The data obtained showed that microalgae are capable of producing biomass in addition to recovering the nutrients contained in the centrate. The best results for biomass productivity and light efficiency were obtained when the centrate was set at 20% with a dilution rate of 0.3 day-1. The biomass productivity was 32.42 g m-2.day-1 while the photosynthetic efficiency was 0.74 gbiomass.E-1 (3.66%). Regarding the nutrients, nitrogen (the majority being in the form of ammonium [NH4+]) and phosphorus were only fixed into biomass when optimal conditions were set; if this was not the case, they were lost to stripping or precipitation. The maximal nutrient removal capacities under the optimal conditions were 28.72 mgN.l-1.day-1 and 3.99 mgP.l-1.day-1. Population changes were determined by the dilution rate set whilst the centrate percentage had little effect. Four strains were present in the culture, Nannochloropsis g. being the main one. Biochemical changes did not vary greatly between the conditions set for the culture, with a composition rich in proteins and carbohydrates being observed. One can conclude that to produce marine microalgal biomass for a range of potential commodities such as feed, biofertilizers and biofuels, it is possible to use centrate from anaerobic digestion as the sole nutrient source, as a way of reducing costs.

AB - Given regulatory developments, it is imperative that water businesses implement effective customer engagement strategies. Among other options, Facebook offers enormous potential given the ability to connect with customers, involve customers in the co-creation of content, obtain real-time feedback on customer preferences and promote water conversation behaviours. This paper examines how effectively 20 large Australian and U.K. water businesses are using Facebook to engage customers. It also identifies how these firms can improve Facebook engagement by optimising posts type, timing, content, frequency and other factors. The total sample included more than 300,000 responses to nearly 17,000 posts between 2010 and 2017. Rapid growth in the utilisation of Facebook by water businesses was observed given the number of posts and customers engaging with this content. The results of the analysis of popular posts identified innovative ways some water businesses are using Facebook posts to promote the health benefits of tap water consumption, water conservation behaviours and responsible wastewater practices. Despite the trends, most firms still make less than one post per day and of those customers who have engaged, most have done with a single response. Further analysis revealed that few posts, and only a relatively small number of customer comments, pertained to water pricing matters. To promote engagement, water businesses must improve post regularity, the degree to which they moderate Facebook discussion, the utilisation of videos and photos, and further consider the underlying content of posts. PMID- 30273771 TI - Two-way switch: Maximizing productivity of tilted panel in membrane bioreactor. AB - Membrane fouling is a major challenge in membrane bioreactors (MBRs) and its effective handling is the key to improve their competitiveness. Tilting panel system offers significant improvements for fouling control but is strictly limited to one-sided panel. In this study, we assess a two-way switch tilting panel system that enables two-sided membranes and project its implications on performance and energy footprint. Results show that tilting a panel improves permeance by up to 20% to reach a plateau flux thanks to better contacts between air bubbles and the membrane surface to scour-off the foulant. A plateau permeance could be achieved at aeration rate of as low as 0.90 l min-1, a condition untenable by vertical panel even at twice of the aeration rate. Switching at short periods (<5min) can maintain the hydraulic performance as in no-switch (static system), enables application of a two-sided switching panel. A comparison of vertical panel under 1.80 l min-1 aeration rate with a switching panel at a half of the rate, switched at 1 min period shows ~10% higher permeance of the later. Since periodic switching consumes a very low energy (0.55% of the total of 0.276 kWh m-3), with reduction of aeration by 50%, the switching tilted panel offers 41% more energy efficient than a referenced full-scale MBR (0.390 kWh m-3). Overall results are very compelling and highly attractive for significant improvements of MBR technologies. PMID- 30273772 TI - Introducing nano-particle-type properties of Tin (n=2-6) clusters. AB - In the present research titanium clusters, Tin (n = 2-6), are studied to highlight their tendency to present nano-particle-type properties as their size grows. Electronic and geometrical structures of clusters and cluster-ligands complexes are obtained at the PBE/QZVP level of theory after density functional theory (DFT) calibration. The correlation between chemical reactivity (hardness) and conductivity with nano-particle-type properties are introduced. Interaction energies of these clusters with N2 and C2H4 ligands are calculated to provide essential information regarding the ascending trend of reactivity as the size of cluster increases. For reactivity, the correlation between the hardness values of titanium clusters and interaction energies are found to be R2 = 0.972 for dissociative adsorption. In addition, the correlation between non-Lewis of pure titanium clusters and size of clusters is R2 = 0.973. For conductivity, the obtained correlation between HOMO-LUMO gap values and the cluster size is R2 = 0.881.

AB - Protic dicationic ionic liquids (PDILs) have attracted growing attention owing to their applications in domains of electrochemistry, proton conducting materials and other diverse areas. In the present work protic dicationic ionic liquids (PDILs) comprising of quaternary ammonium-, imidazolium- or pyrrolidinium dications and bis(trifluoromethanesulfonyl)imide (Tf2N?) anion have been modelled as the dication-(Tf2N)2 complexes. Electronic structure, vibrational and 1H NMR spectra of these complexes have been derived employing the M06-2x density functional theory. Theoretical calculations have shown that the strength of cation-anion binding follows the order: methylpyrrolidinum > quaternary ammonium > butylpyrrolidinium > imidazolium, which can be attributed to number and strength of N-H---O and C-H---O interactions. The dication-(Tf2N)2 complexes emerge with signature in frequency up-shift of the characteristic N-H stretching in their infrared spectra. Underlying molecular interactions are unveiled through natural bond orbital analyses, Quantum theory of atoms in molecules (QTAIM) and noncovalent interaction reduced density gradient method. The calculations have shown that cation-anion binding energies increase linearly with kinetic energy density component G(r) in QTAIM analysis and proton affinities in the PDILs. A correlation between change in free energies accompanying the dication-(Tf2N)2 complexes and proton affinities has also been established. PMID- 30273774 TI - Growth hormone and Insulin-like growth factor-I (IGF-I) modulate the expression of L-type amino acid transporters in the muscles of spontaneous dwarf rats and L6 and C2C12 myocytes. AB - OBJECTIVE: Branched-chain amino acids (BCAAs) have been reported to inhibit several types of muscle atrophy via the activation of the mechanistic target of rapamycin complex 1 (mTORC1). However, we previously found that BCAA did not activate mTORC1 in growth hormone (GH)-deficient spontaneous dwarf rats (SDRs), and that GH restored the stimulatory effect of BCAAs toward the mTORC1. The objective of this study was to determine whether GH or Insulin-like growth factor I (IGF-I) stimulated the expression of L-type amino acid transporters (LATs) that delivered BCAAs, and whether LATs were involved in the mTORC1 activation. DESIGN: After the continuous administration of GH, cross-sectional areas (CSAs) of muscle fibers and LAT mRNA levels in the skeletal muscles of SDRs were compared to those from the SDRs that received normal saline. The effect of GH and IGF-I on LAT mRNA levels were determined in L6 and C2C12 myocytes. The effects of 2 aminobicyclo[2.2.1]heptane-2-carboxylic acid (BCH), a blocker for LATs, and LAT1 siRNA on mTORC1 activation and cell functions were examined in C2C12 cells. RESULTS: GH increased LAT1 and LAT4 mRNA levels in accordance with the increase in CSAs of muscle fibers in SDRs. IGF-I, and not GH, increased LAT1 mRNA levels in cultured L6 myocytes. IGF-I also increased LAT1 mRNA level in another myocyte line, C2C12. Furthermore, IGF-I reduced LAT3 and LAT4 mRNA levels in both cell lines. GH reduced LAT3 and LAT4 mRNA levels in L6 cells. BCH decreased basal C2C12 cell proliferation and reduced IGF-I-induced phosphorylation of 4E-BP1 and S6K, both of which are mTORC1 targets, but LAT1 siRNA did not affect the phosphorylation. This suggests that BCH may exert its effect via other pathway than LAT1. CONCLUSIONS: IGF-I increased LAT1 mRNA level in myocytes. However, the role of LAT1 in IGF-I-induced mTORC1 activation and cell functions remains unclear. PMID- 30273775 TI - 'Recurrent losers unite': Online forums, evidence-based activism, and pregnancy loss. AB - Women with recurrent pregnancy loss face unique challenges associated with the social invisibility of their condition, patchy medical knowledge about it, and often intransigent positions of doctors. We approach online forums as sites of knowledge production and examine discussions among women with recurrent miscarriages. We observe that some forum participants gather, summarize, and share experience-based and research-based information in order to challenge certain medical conceptions. We describe these efforts as an example of individual patients' evidence-based activism enabled by new media platforms and other technoscientific tools available to the public. PMID- 30273776 TI - Watch for motorcycles! The effects of texting and handheld bans on motorcyclist fatalities. AB - Motorcyclists account for a much higher proportion of traffic fatalities relative to the share of motorcycles among all motor vehicles and vehicle miles driven in the U.S. In this paper, we posit that motorcyclists may be particularly vulnerable to the risks of distracted driving by others. Specifically, we examine whether state-specific texting/handheld bans significantly influence motorcyclist fatalities in the U.S. We use state-specific traffic fatality data in the U.S. (2005-2015, N = 550) from the Fatality Analysis Reporting System (FARS) merged with state-specific characteristics, texting/handheld device laws, and other traffic policies. Although research is mixed on the effectiveness of texting/handheld bans for overall traffic fatalities, our findings indicate that motorcyclists are at elevated risk of being a victim of distracted driving and thus could greatly benefit from these policies. This result is driven mainly by multiple-vehicle crashes (e.g., car hitting motorcycle) as opposed to single vehicle crashes. Policy makers should consider strengthening texting/handheld bans along with their enforcement to improve safety and save lives, especially among motorcyclists. . PMID- 30273777 TI - Parental recognition of preadolescent mental health problems: Does stigma matter? AB - RATIONALE: Parents are one of several key gatekeepers to mental health (MH) services for adolescents with MH problems. Parental MH stigma is a significant barrier to treatment, yet little is known about how stigma may bias parental recognition of mental illness in youth. OBJECTIVE: This study examines how stigma influences a critical and early stage of the help-seeking process-the recognition of MH problems in preadolescents by their parents. METHOD: Parents from a school based anti-stigma intervention study were analyzed. Logistic regressions examined the association of stigma with parental recognition of MH problems in their preadolescent child (10-12 years old) and that of two preadolescent vignette characters described as having bipolar disorder and social anxiety disorder. RESULTS: The more parents desired their preadolescent child to avoid interaction with individuals with a mental illness-that is, to be more socially distant-the less likely these parents believed their child had a MH problem, controlling for parent-reported MH symptoms and other covariates. This pattern was prominent among parents who reported high symptoms in their child. Social distance had no bearing on whether parents recognized the vignette characters as having a problem. Avoidance of individuals with a mental illness and knowledge/positive MH attitudes were not associated with problem recognition. CONCLUSION: Stigmatizing attitudes of parents may be detrimental when trying to understand the psychopathology of their own preadolescent children but not preadolescents outside their family. Stigma may present itself as a barrier to problem recognition because it may impose a significant personal cost on the family, thereby affecting the help-seeking process earlier than considered by previous work. PMID- 30273778 TI - A Nanopore Sequencing-Based Assay for Rapid Detection of Gene Fusions. AB - Structural chromosomal rearrangements leading to gene fusions are strong driver mutations in a variety of tumors. Identification of specific gene fusions can be essential for distinguishing benign from malignant conditions and for recognizing specific subtypes of neoplasms that can have different management and prognosis. Rapid identification of gene fusions is particularly critical for patients with acute leukemia who cannot wait more than a few days before initiating treatment and for whom treatment can be dramatically different depending on the leukemia subtype. We have developed an assay for rapid detection of oncogenic gene fusions (within 24 hours) that takes advantage of the long reads and real-time data generation of the Oxford Nanopore MinION sequencing system. By using a modification of the anchored multiplex PCR method for library construction, we confidently identified BCR-ABL1 fusion transcripts, with >100 reads within 15 minutes of sequencing. By using formalin-fixed, paraffin-embedded specimens routinely tested in our clinical molecular laboratory, fusions were successfully identified within 5 hours from acquisition of Illumina-ready libraries and 30 minutes of sequencing initiation, including cases diluted to a tumor fraction of 5%. In conclusion, we have developed a nanopore-based sequencing assay that can decrease turnaround time for detection of fusion oncogenes and may be a valid approach for laboratories with low specimen volume and for cases in need of rapid results. PMID- 30273779 TI - In Silico Mutator: In Silico MutatorSoftware for Bioinformatics Pipeline Validation of Clinical Next-Generation Sequencing Assays. AB - Lack of reliable reference samples containing different mutations of interest across large sets of disease-relevant loci limits the extensive validation clinical next-generation sequencing (NGS) assays and their associated bioinformatics pipelines. Herein, we have generated a publicly available, highly flexible tool, in silico Mutator (insiM), to introduce point mutations, insertions, deletions, and duplications of any size into real data sets of amplicon-based or hybrid-capture NGS assays. insiM accepts an alignment file along with target territory and produces paired-end FASTQ files containing specified mutations via modification of original sequencing reads. Mutant signal is, thus, generated within the context of existing real-world data to most closely mimic assay performance. Resulting files may then be passed through the assay's bioinformatics pipeline to assist with assay/bioinformatics validation and to identify performance gaps in detection. To establish the basic functionality of the software, a series of simulation experiments with varying mutation types, sizes, and allele frequencies were performed across the entire clinical territory of hybrid-capture and amplicon-based clinical assays developed at The University of Chicago. This work demonstrates the utility of insiM as a supplementary tool during the validation of an NGS assay's bioinformatics pipeline. PMID- 30273780 TI - Accurate and Sensitive Analysis of Minimal Residual Disease in Acute Myeloid Leukemia Using Deep Sequencing of Single Nucleotide Variations. AB - Minimal residual disease (MRD) in acute myeloid leukemia (AML) is of major prognostic importance. The genetic landscape of AML is characterized by numerous somatic mutations, which constitute potential MRD markers. Leukemia-specific mutations can be identified with exome sequencing at diagnosis and assessed during follow-up at low frequencies by using targeted deep sequencing. Our aim was to further validate this patient-tailored assay for substitution mutations. By applying a statistical model, which corrects for position-specific errors, a limit of detection for single nucleotide variations of variant allele frequency (VAF) of 0.02% was achieved. The assay was linear in MRD range (0.03% to 1%) with good precision [CV, 4.1% (2.2% to 5.7%) at VAF 1% and 13.3% (8.8% to 19.4%) at VAF 0.1%], and low relative bias [7.9% (2.5% to 15.3%) at VAF 1%]. When applied to six childhood AML cases and compared with multiparameter flow cytometry for MRD analysis, deep sequencing showed concordance and superior sensitivity. Further high concordance was found with expression of fusion transcripts RUNX1 RUNX1T1 and KMT2A-MLLT10. The deep sequencing assay also detected mutations in blood when VAF in bone marrow exceeded 0.1% (n = 19). In conclusion, deep sequencing enables reliable detection of low levels of residual leukemic cells. Introduction of this method in patient care will allow for highly sensitive MRD surveillance in virtually every patient with AML. PMID- 30273781 TI - Plastic surgery or primary care? Altruistic preferences and expected specialty choice of U.S. medical students. AB - Understanding physicians' decisions when faced with conflicts between their own financial self-interest and patients' economic or health interests is of key importance in health economics and policy. This issue is especially salient in certain medical specialties where less altruistic behavior of physicians can yield significant financial gains. This study examines experimentally measured altruistic preferences of medical students from schools around the U.S., and whether these preferences predict those students' expected medical specialty choice. The experimental design consists of a set of computer-based revealed preference decision problems, which ask the experimental subjects to allocate real money between themselves and an anonymous person. These data are used to derive an innovative measure of altruism for each participant. I then examine the association between altruism and expected specialty choice, after controlling for an extensive set of covariates collected from an accompanying survey questionnaire. Medical students with a lower degree of altruism are significantly more likely to choose high-income specialties, conditioning on an extensive set of covariates. This altruism measure is more predictive of income of specialty choice than a wide range of other characteristics, including parental income, student loan amount and Medical College Admission Test (MCAT) score. On the other hand, the altruism measure does not predict choosing primary care specialties. I also find that altruism predicts students' self-reported likelihood of practicing medicine in an underserved area. PMID- 30273782 TI - Environmental pollution and toxic substances: Cellular apoptosis as a key parameter in a sensible model like fish. AB - The industrial wastes, sewage effluents, agricultural run-off and decomposition of biological waste may cause high environmental concentration of chemicals that can interfere with the cell cycle activating the programmed process of cells death (apoptosis). In order to provide a detailed understanding of environmental pollutants-induced apoptosis, here we reviewed the current knowledge on the interactions of environmental chemicals and programmed cell death. Metals (aluminum, arsenic, cadmium, chromium, cobalt, zinc, copper, mercury and silver) as well as other chemicals including bleached kraft pulp mill effluent (BKME), persistent organic pollutants (POPs), and pesticides (organo-phosphated, organo chlorinated, carbamates, phyretroids and biopesticides) were evaluated in relation to apoptotic pathways, heat shock proteins and metallothioneins. Although research performed over the past decades has improved our understanding of processes involved in apoptosis in fish, yet there is lack of knowledge on associations between environmental pollutants and apoptosis. Thus, this review could be useful tool to study the cytotoxic/apoptotic effects of different pollutants in fish species. PMID- 30273783 TI - A lipidomic approach to understand copper resilience in oyster Crassostrea hongkongensis. AB - Copper (Cu) can cause oxidative stress and inflammatory responses, and there is arising evidence between Cu toxicity and lipid disturbance. In this study, we examined the relationships between Cu exposure and lipid metabolism in an estuarine oyster (Crassostrea hongkongensis) and aimed to understand the effects and resilience strategies of Cu on oyster metabolism. We exposed the oysters to waterborne Cu (10 and 50 MUg/L) and measured the physiological changes (condition index and clearance rate), lipid accumulation and lipid peroxidation in the oysters. We found more altered lipid responses in oysters exposed to a lower Cu concentration (10 MUg/L), and speculated that oysters exposed to 50 MUg/L may upregulate the defenses. We further evaluated the changes in lipidome profiling of the Cu-exposed oysters in aspects of membrane dynamics, lipid signaling and energy metabolism. We documented the phospholipid remodeling as well as quick modulation in inflammatory responses and extensive vesicle formation for subcellular compartmentalization and autophagosome formation, as well as the possible impacts on mitochondrial bioenergetics in the Cu-exposed oysters. The lipidomics approach provided a comprehensive lipid profile of possible alteration by Cu exposure. In combination with other omics approaches, it may be possible to elucidate the pathways and mechanisms in stress acclimation and resilience associated between Cu contamination and lipid metabolism. PMID- 30273784 TI - Serum cytokine profiles in patients with chronic obstructive pulmonary disease associated pulmonary hypertension identified using protein array. AB - Pulmonary hypertension (PH) is a common complication of chronic obstructive pulmonary disease (COPD) and is a significant risk factor for hospitalization and shortened life expectancy. Therefore, developing new serum biomarkers for early diagnosis and prognosis of COPD associated PH is crucial. In the present study, a solid-phase antibody array simultaneously detecting multiple proteins was used to search specific COPD associated PH biomarkers, with COPD patients and healthy subjects as control groups. As a result, compared to the COPD and healthy groups, the levels of MCP-4, SDF-1 alpha, CCL28, Adipsin, IL-28A, CD40 and AgRP were uniquely altered in COPD patient serum with pulmonary hypertension. Among these proteins, CCL28, MCP-4, CD40, AgRP and IL-28A were identified to be differentially expressed in COPD patients with hypertension, indicating that these cytokines may serve as novel biomarkers for the diagnosis and prognosis of COPD associated pulmonary hypertension. PMID- 30273785 TI - Anacardic acid suppresses fibroblast-like synoviocyte proliferation and invasion and ameliorates collagen-induced arthritis in a mouse model. AB - Anacardic acid, which is abundant in nutshell of Anacardium occidentale, has multiple pharmacological activities. In this study, we examined the therapeutic potential of anacardic acid in treating rheumatoid arthritis (RA). We explored the effects of anacardic acid on collagen-induced arthritis (CIA) in mice and on the proliferation and invasion of RA fibroblast-like synoviocytes (RA-FLSs). The underlying molecular mechanism was investigated. Anacardic acid treatment markedly suppressed paw swelling, joint destruction, and arthritis scores in CIA mice. The serum levels of tumor necrosis factor alpha (TNF- alpha) and interleutkin-1beta (IL- 1beta) were significantly lowered by anacardic acid. In vitro assays demonstrated that anacardic acid impaired the proliferation and invasion abilities of RA-FLSs in the presence of TNF- alpha or IL- 1beta. Western blot analysis revealed the reduction of Akt protein expression and phoshporylation in RA-FLSs by anacardic acid. However, the mRNA level of Akt remained unchanged. Anacardic acid treatment significantly increased the expression of miR-633 in RA-FLSs. Akt was identified as a novel target of miR 633. Overexpression of miR-633 significantly inhibited the proliferation and invasion of RA-FLSs, which was rescued by enforced expression of Akt. Depletion of miR-633 prevented anacardic acid-mediated suppression of proliferation and invasion of RA-FLSs, which was accompanied by increased expression of Akt protein. In conclusion, anacardic acid may serve as a promising agent in the treatment of RA. PMID- 30273786 TI - Reduction of bacterial integrity associated with dam construction: A quantitative assessment using an index of biotic integrity improved by stability analysis. AB - Rivers are extensively regulated by damming, yet the effects of such interruption on bacterial communities have not been assessed quantitatively. To fill this gap, we proposed a bacteria-based index of biotic integrity (Ba-IBI) by using bacterial community dataset collected from the Three Gorges Reservoir and its upper reaches. Stability analysis based on bacterial resistance (RS) and resilience (RL) to external disturbance was conducted to improve the performance of the index. Four core metrics, i.e. the ratio of Bacilli, Bacteroidetes and Clostridia to Alphaproteobacteria (BBC/A), Oxalobacteraceae, Methanotrophs and Thermophiles were selected after range, responsive and redundancy tests. The improved Ba-IBI, ranging from 1.04 to 4.10, was better at distinguishing sites with or without direct dam effects compared with the unimproved one. The index values maintained high in the riverine sites while reducing in the reservoir, demonstrating the negative influence of dam construction on bacterial integrity. Based on the assessment results, 23.1%, 46.2% and 30.8% sampling sites were large, moderately and little affected by damming, respectively. A Random Forest (RF) regression model was trained and tested, offering a valid prediction of the input Ba-IBI and environmental parameters. Sensitivity analysis revealed the significant contributions of flow velocity towards the predicting process performance, indicating the importance of hydrodynamic conditions on determining the spatial variability of bacterial communities. This study provides not only a first quantitative insight for assessing bacterial response to damming, but also a guideline for applying the improved index in the dam regulation and ecological protection. PMID- 30273787 TI - Considerations for upscaling individual effects of wind energy development towards population-level impacts on wildlife. AB - The expansion of wind energy poses challenges to policy- and decision-makers to address conflicts with wildlife. Conflicts are associated with impacts of existing and planned projects on wildlife, and associated difficulties of prediction where impacts are subject to considerable uncertainty. Many post construction studies have demonstrated adverse effects on individuals of various bird and bat species. These effects may come in the form of collision-induced mortality or behavioral or physiological changes reducing the fitness of individuals exposed to wind energy facilities. Upscaling these individual effects to population impacts provides information on the true value of interest from a conservation point of view. This paper identifies methodological issues associated when moving from individual effects to population impacts in the context of wind energy. Distinct methodological approaches to predict population impacts are described using published case studies. The various choices of study design and metrics available to detect significant changes at the population level are further assessed based on these. Ways to derive impact thresholds relevant for decision-making are discussed in detail. Robust monitoring schemes and sophisticated modelling techniques may inevitably be unable to describe the whole complexity of wind and wildlife interactions and the natural variability of animal populations. Still, they will provide an improved understanding of the response of wildlife to wind energy and better-informed policies to support risk based decision-making. Policies that support the use of adaptive management will promote assessments at the population level. Providing information to adequately balance the development of wind energy with the persistence of wildlife populations. PMID- 30273788 TI - How practitioners integrate decision triggers with existing metrics in conservation monitoring. AB - Decision triggers are defined thresholds in the status of monitored variables that indicate when to undertake management, and avoid undesirable ecosystem change. Decision triggers are frequently recommended to conservation practitioners as a tool to facilitate evidence-based management practices, but there has been limited attention paid to how practitioners are integrating decision triggers into existing monitoring programs. We sought to understand whether conservation practitioners' use of decision triggers was influenced by the type of variables in their monitoring programs. We investigated this question using a practitioner-focused workshop involving a structured discussion and review of eight monitoring programs. Among our case studies, direct measures of biodiversity (e.g. native species) were more commonly monitored, but less likely to be linked to decision triggers (10% with triggers) than measures being used as surrogates (54% with triggers) for program objectives. This was because decision triggers were associated with management of threatening processes, which were often monitored as a surrogate for a biodiversity asset of interest. By contrast, direct measures of biodiversity were more commonly associated with informal decision processes that led to activities such as management reviews or external consultation. Workshop participants were in favor of including more formalized decision triggers in their programs, but were limited by incomplete ecological knowledge, lack of appropriately skilled staff, funding constraints, and/or uncertainty regarding intervention effectiveness. We recommend that practitioners consider including decision triggers for discussion activities (such as external consultation) in their programs as more than just early warning points for future interventions, particularly for direct measures. Decision triggers for discussions should be recognized as a critical feature of monitoring programs where information and operational limitations inhibit the use of decision triggers for interventions. PMID- 30273789 TI - Predictors of long-term outcome of CBT for youth with anxiety disorders treated in community clinics. AB - Cognitive behavioral therapy (CBT) has proven long-term effects in youth with anxiety disorders. However, only a few studies have examined predictors of long term outcomes of CBT treatment. The present study investigated possible predictors of long-term treatment outcomes in youth with mixed anxiety disorders treated in community mental health clinics. A total of 139 youth (mean age at assessment 15.5 years, range 11-21 years) with a principal diagnosis of separation anxiety disorder, social anxiety disorder, and/or generalized anxiety disorder were evaluated a mean of 3.9 years post-treatment (range 2.2-5.9 years). Outcomes were loss of all inclusion anxiety diagnoses, loss of the principal inclusion anxiety diagnosis, and changes in youth- and parent-rated youth anxiety symptoms. Predictors encompassed youth, parent and demographic factors, and post treatment recovery. The most consistent finding was that low family social class predicted poorer outcomes. Higher treatment motivation was associated with better outcome whereas a diagnosis of social anxiety was associated with poorer outcome. Identified predictors extend on previous findings from efficacy trials, and the results indicate a need for more specific treatment protocols. PMID- 30273790 TI - Use of cooking oils in a 2:1 ratio classical ketogenic diet for intractable pediatric epilepsy: Long-term effectiveness and tolerability. AB - BACKGROUND: In many parts of eastern Asia, rice is a dietary staple and therefore the ketogenic diet (KD) can be difficult to administer. The aim of this study was to assess the long-term effectiveness and tolerability of the classical KD using a 2:1 ratio of fat to protein plus net carbohydrates, which is lower than the ratios of 3:1 or 4:1 typically used in classical KD for intractable pediatric epilepsy. MATERIALS: In this prospective study, cooking oils rich in polyunsaturated fatty acid or omega 3 fatty acids, such as olive oil, camellia oil, linseed oil, grape seed oil, and/or perilla oil were used to formulate a classical KD with a 2:1 ratio for infants and children diagnosed with medically intractable epilepsy from April 2002 to April 2018. Subjects received the diet for at least 3 months. The efficacy of the diet was analyzed at 3, 6, 12, and 24 months, and at > 3 years. Tolerability during the period of diet administration was analyzed by medical records and parental reports. RESULTS: Sixty-three subjects, 29 males and 34 females, were enrolled from April 2002 to April 2018. The median age at diet initiation was 2 years 11 months. The median duration of adherence to the diet was 1 year 2 months. The seizure-free rate was 14%, 16%, 17%, 14%, and 14% at 3, 6, 12, and 24 months', and at > 3 years' follow-up, respectively. A greater than 50% seizure reduction was achieved in 52%, 43%, 40%, 33%, and 30% of subjects at each time point. The dietary compliance rate was 100%, 70%, 60%, 35%, and 27% at each follow-up time point. The reasons for discontinuation of the KD were the lack of further improvement in seizure frequency, seizure freedom achieved, food refusal, hyperlipidemia, and poor parental compliance in 38%, 11%, 5%, 2%, and 2% of subjects, respectively. Gastrointestinal discomfort was the most common adverse effect. CONCLUSION: The classical KD with a 2:1 ratio showed clinical effectiveness and tolerability in intractable pediatric epilepsy after long-term follow-up. PMID- 30273791 TI - Clinical and imaging features distinguishing Susac syndrome from primary angiitis of the central nervous system. AB - INTRODUCTION: To assess clinical and/or imaging features useful to distinguish between Susac syndrome (SuS) and primary angiitis of central nervous system (PACNS). METHODS: Multicenter retrospective analysis of two cohorts of Argentine patients diagnosed with SuS and PACNS. RESULTS: 13 patients diagnosed with SuS (6 women and 7 men, mean age 35 +/- 10 years) and 15 with PACNS (10 women and 5 men, mean age 44 +/- 18 years) were analyzed. Cognitive impairment (11 out of 13 patients vs. 5 out of 15, p = .006), ataxia (7 out of 13 vs. 2 out of 15, p = .042) and auditory disturbances (7 out of 13 vs. 0 out of 15, p = .003) were more frequent in SuS patients; whereas seizures were more frequent in PACNS patients (8 out of 15 vs. 1 out of 13, p = .035). On MRI, corpus callosum (CC) involvement was observed more often in SuS, with abnormalities in CC genu, in 13 out of 13 SuS patients vs. only 2 out of 15 PACNS patients (p < .001); in CC body these were present in 13 out of 13 SuS patients vs. 1 out of 15 PACNS patients, (p < .001); and in CC splenium in 12 out of 13 Sus patients vs. 1 of 15 PACNS, p < .001). Cortical lesions were more frequent in PACNS patients (10 out of 15 vs. 3 out of 13 SuS patients, p = .02), as were hemorrhages (5 out of 15 vs. 0 out of 13 SuS, p = .04) and multiple basal ganglia infarcts (7 out of 15 vs. 1 out of 13 Sus, p = .037). CONCLUSION: Specific clinical and/or MRI findings may help distinguish SuS from PACNS with potential therapeutic implications. PMID- 30273792 TI - Alexithymia and reactive aggression: The role of the amygdala. AB - Past research suggests an association between reactive aggression and alexithymia, but neural mechanisms underlying this association remain unknown. Furthermore, the relationship between proactive aggression and alexithymia remains untested. This study aimed to: (1) test whether alexithymia is more related to reactive than proactive aggression; and (2) determine whether amygdala, insula, and/or anterior cingulate cortical (ACC) volume could be neurobiological mechanisms for this association. One hundred and fifty-six community males completed the Reactive-Proactive Aggression Questionnaire and the Toronto Alexithymia Scale. Amygdala, insula, and ACC volumes were assessed using MRI. Alexithymia was positively associated with reactive but not proactive aggression. Alexithymia was positively and bilaterally associated with amygdala and anterior cingulate volumes. Reactive aggression was positively associated with right amygdala volume. Controlling for right amygdala volume rendered the alexithymia-reactive aggression relationship non-significant. Results suggest that increased right amygdala volume is a common neurobiological denominator for both alexithymia and reactive aggression. Findings suggest that greater right hemisphere activation may reflect a vulnerability to negative affect, which in turn predisposes to experiencing negative emotions leading to increased aggression. Findings are among the first to explicate the nature of the alexithymia-aggression relationship, with potential clinical implications. PMID- 30273793 TI - White matter microstructural correlates of relapse in alcohol dependence. AB - Identification of neural correlates of relapse to alcohol after treatment is clinically important as it may inform better substance abuse treatment. Few studies have specifically analyzed the white matter microstructure in treatment seekers as it might relate to relapse risk versus long-term abstinence. Using 4 Tesla diffusion tensor imaging, we compared two groups of one-month-abstinent treatment-seekers, who were classified based on their drinking status between six and nine months after treatment initiation. We hypothesized that subsequent relapsers had greater white matter microstructural deficits in specific brain regions than long-term abstainers. At one month of abstinence, 37 future relapsers versus 25 future abstainers had lower fractional anisotropy (a measure of axonal organization and membrane integrity) in the corpus callosum and right stria terminalis/fornix, higher diffusivity in the genu of the corpus callosum, left and right stria terminalis/fornix, and lower diffusivity in left anterior corona radiata. These differences existed despite similar lifetime and recent drinking and smoking histories in the groups. Longer smoking duration in relapsers was associated with lower fractional anisotropy in right stria terminalis/fornix. The study identified specific microstructural biomarkers of alcohol relapse risk in adults, contributing to the definition of a neurobiological relapse risk profile in alcohol use disorder. PMID- 30273794 TI - Associations between depression, anxious arousal and manifestations of psychological inflexibility. AB - BACKGROUND AND OBJECTIVES: Psychological inflexibility exhibits across multiple facets of functioning, including thinking styles, personality, cognitive shifting, emotion, and physiology, with many of these manifestations showing associations with depression. As such, these facets might be part of an overarching latent construct of psychological inflexibility that explains associations with depression. We predicted that (1) five facets of inflexibility (perseverative thinking, personality rigidity, attention-shifting, negative emotional inertia, and low respiratory sinus arrhythmia reactivity) would load onto a unique latent construct of psychological inflexibility. Further, we hypothesized this latent construct of psychological inflexibility would be (2) significantly associated with higher depression; and (3) associated with depression to a greater extent than anxious arousal. METHODS: Seventy-five adult community participants completed measures assessing the five indices of inflexibility and self-report measures of depression and anxious arousal. RESULTS: Structural equation modeling identified a latent inflexibility construct reflected by perseverative thinking, personality rigidity, and emotional inertia, but did not include attention-shifting or RSA reactivity. The inflexibility construct was positively associated with depression and anxious arousal, but more strongly associated with depression than with anxious arousal. LIMITATIONS: Limitations included a small sample size, cross-sectional approach, and dimensional measures of depression and anxious arousal. CONCLUSIONS: Findings provide preliminary support that multiple facets of inflexibility may emerge from a broader overarching vulnerability for internalizing psychopathology. This overarching inflexibility construct may have stronger associations with depression than with anxious arousal. PMID- 30273796 TI - Reinforcement learning across the rat estrous cycle. AB - Reinforcement learning, the process by which an organism flexibly adapts behavior in response to reward and punishment, is vital for the proper execution of everyday behaviors, and its dysfunction has been implicated in a wide variety of mental disorders. Here, we use computational trial-by-trial analysis of data of female rats performing a probabilistic reward learning task and demonstrate that core computational processes underlying value-based decision making fluctuate across the estrous cycle, providing a neuroendocrine substrate by which gonadal hormones may influence adaptive behavior. PMID- 30273795 TI - Low-dose blue light irradiation enhances the antimicrobial activities of curcumin against Propionibacterium acnes. AB - Propionibacterium acnes (P. acnes) is an opportunistic infection in human skin that causes acne vulgaris. Antibiotic agents provide the effective eradication of microbes until the development of drug-resistant microbes. Photodynamic inactivation (PDI) is a non-antibiotic therapy for microbial eradication. In this study, the visible blue light (BL, lambdamax = 462 nm) was used to enhance the antimicrobial activities of curcumin, a natural phenolic compound. Individual exposure to curcumin or BL irradiation does not generate cytotoxicity on P. acnes. The viability of P. acnes was decreased significantly in 0.09 J/cm2 BL with 1.52 MUM of curcumin. Furthermore, the low-dose blue light irradiation triggers a series of cytotoxic actions of curcumin on P. acnes. The lethal factors of photolytic curcumin were investigated based on the morphology of P. acnes by SEM and fluorescent images. The membrane disruption of microbes was observed on the PDI against P. acnes. Chromatography and mass spectrometry techniques were also used to identify the photolytic metabolites. Curcumin could be photolysed into vanillin through BL irradiation, which presents a strong linear relationship in quantitation. Because the safety of blue light in mammalian cell has been proven, the photolytic curcumin treatment could support non-antibiotic therapy to eradicate P. acnes on clinical dermatology. PMID- 30273797 TI - Amygdalar activity predicts future incident diabetes independently of adiposity. AB - While it is established that psychosocial stress increases the risk of developing diabetes mellitus (DM), two key knowledge gaps remain: 1) the neurobiological mechanisms that are involved in mediating that risk, and 2) the role, if any, that adiposity plays in that mechanism. We tested the hypotheses that: 1) metabolic activity in the amygdala (AmygA), a key center involved in the neurobiological response to stress, associates with subsequent DM risk, and 2) this association is independent of adiposity. AmygA and adipose tissue volumes were measured, and serial blood assessments for DM were obtained in 232 subjects who underwent combined 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) imaging. Higher baseline AmygA predicted subsequent, new-onset DM, independently of adiposity and other DM risk factors. Furthermore, higher adiposity only increased DM risk in the presence of higher AmygA. In a separate cross-sectional cohort, higher AmygA associated with higher insulin resistance. Accordingly, the current study shows, for the first time, that activity in a stress-responsive neural region predicts the onset of DM. Further, we observed that this neurobiological activity acts independently of, but also synergistically with adiposity to increase DM risk. These findings suggest novel therapeutic targets to help manage and possibly prevent DM. PMID- 30273799 TI - Keeping up with advances in axon guidance. AB - Twenty-five years after the discovery of the first chemotropic molecules for growing axons, what are the new findings? This review describes the latest progress made in our understanding of the molecular control of axonal guidance in the vertebrate nervous system. Special focus will be given to new molecular players, their source and location in vivo, and the role of membrane/receptor trafficking and RNA-based mechanisms in axon guidance cue signalling. PMID- 30273798 TI - The left temporal pole is a convergence region mediating the relation between names and semantic knowledge for unique entities: Further evidence from a "recognition-from-name" study in neurological patients. AB - Prior research has implicated the left temporal pole (LTP) as a critical region for naming semantically unique items, including famous faces, landmarks, and musical melodies. Most studies have used a confrontation naming paradigm, where a participant is presented with a stimulus and asked to retrieve its name. We have proposed previously that the LTP functions as a two-way, bidirectional convergence region brokering between conceptual knowledge and proper names for unique entities. Under this hypothesis, damage to the LTP should result in a "two way" impairment: (1) defective proper name retrieval when presented with a unique stimulus (as shown in prior work); and (2) defective concept retrieval when presented with a proper name. Here, we directly tested the second prediction using a "recognition-from-name" paradigm. Participants were patients with LTP damage, brain-damaged comparisons with damage outside the LTP, and healthy comparisons. Participants were presented with names of famous persons (e.g., "Marilyn Monroe"), landmarks (e.g., "Leaning Tower of Pisa"), or melodies (e.g., "Rudolph the Red-Nosed Reindeer") and were asked to provide conceptual knowledge about each. We found that individuals with damage to the LTP were significantly impaired at conceptual knowledge retrieval when given names of famous people and landmarks (but this finding did not hold for melodies). This outcome supports the theory that the LTP is a bidirectional convergence region for proper naming, but suggests that melody retrieval may rely on processes different from those supported by the LTP. PMID- 30273800 TI - Cross-sensitivity of psychiatric and behavioral side effects with antiepileptic drug use. AB - PURPOSE: To determine rates of cross-sensitivity of intolerable psychiatric and behavioral side effects (IPBSEs) among commonly used antiepileptic drugs (AEDs) in adult patients with epilepsy. METHODS: IPBSE was defined as a psychiatric or behavioral side effect attributed to AED use that led to a decrease in dose or cessation of an AED. Cross-sensitivity was calculated and was defined as the likelihood of developing IPBSE to a specific AED given IPBSE to another AED. Our sample consisted of 2312 adult patients that were prescribed 2 or more AEDs. Non AED confounders and were controlled for in all analyses. RESULTS: Among the 2312 patients, 20.2% of patients who had taken at least 2 AEDs had IPBSE(s) attributed to at least one AED; 3.5% had IPBSE to two or more AEDs. History of treated depression and psychosis were found to be significant predictors (p < 0.001) of developing IPBSE and were controlled for in all AED-specific analyses. Cross sensitivity was seen between LEV and ZNS (p < 0.001). There was a significant increase in odds of experiencing IPBSE to LEV (41.5%; OR = 2.7; p < 0.001) or ZNS (22.1%; OR = 3.5; p < 0.001) given a patient had IPBSE to another AED compared to having no IPBSE to other AEDs (20.5% and 7.5%, respectively). CONCLUSION: History of depression and psychosis increased risk of developing IPBSE to AEDs. The probability of experiencing IPBSE increased for a patient taking LEV or ZNS if the patient experienced IPBSE to another AED. Our results may be clinically useful for predicting IPBSE associated with certain AEDs. PMID- 30273801 TI - Perspectives of psychiatric investigators and IRB chairs regarding benefits of psychiatric genetics research. AB - There is hope that psychiatric genetics inquiry will provide important insights into the origins and treatment of mental illness given the burden of these conditions. We sought to examine perspectives of psychiatric genetic investigators regarding the potential benefits of genetic research in general and the potential benefits of genetic research for the diagnosis and treatment of mental illnesses specifically. We compared investigator attitudes with those of chairs of Institutional Review Boards (IRBs) entrusted with evaluating the benefits and risks of human research studies. Two groups directly engaged with the conduct and oversight of psychiatric genetic research were examined (psychiatric investigators, n = 203; IRB Chairs, n = 183). Participants rated 15 survey items regarding current and future benefits of general genetic research, possible benefits of psychiatric genetic research, and the importance to society of genetic vs. non-genetic research examining causes and treatments of illnesses. Investigators and IRB Chairs strongly endorsed the future benefits of general genetic research for society and for the health of individuals; compared to IRB Chairs, investigators were more positive about these benefits. Even after adjusting for demographic variables, psychiatric genetic investigators were significantly more optimistic about genetic research compared with IRB Chairs. Both groups were moderately optimistic about the possible benefits of genetic research related to mental illness. Greater optimism was seen regarding new or personalized medications for mental illnesses, as well as genetic predictive testing of mental illnesses. Greater precision and circumspection about the potential benefits of psychiatric genetic research are needed. PMID- 30273802 TI - Men are from Mars: The challenges of communicating as a male nursing student. AB - Male-female communication within nursing is often fraught with difficulties especially for male nurses as the try and assimilate themselves into a female dominated profession. It is clear that men and women possess different communication styles. Men tend to be forthright and to the point. Women on the other hand often view the world as a network of connections, as a negotiation for closeness and support and therefore centred on maintaining solidarity. The aim of this study was to explore the lived-experience of a group of male nursing students using Colaizzi's seven step data analysis within the phenomenological empirical framework. The central theme "Men are from Mars" identified two subthemes which included: calling a spade a spade in world of shovels and conscientious objector from the margins. Communication for the men in this study was difficult. The participants were sensitive of what and how they communicated could be misinterpreted which often left them feeling isolated. They were often perplexed how the female students spoke to and about each. The men on the other hand were open and honest in the way they communicated with each other; there was not misinterpretation the men knew exactly where they stood with each other. PMID- 30273803 TI - A collaborative approach to the implementation of a structured clinical handover tool (iSoBAR), within a hospital setting in metropolitan Western Australian: A mixed methods study. AB - The aim of this study was to determine the effectiveness of an education intervention for the implementation of the clinical handover tool iSoBAR, in an acute setting. A quantitative, descriptive survey design, using pre and post survey data before and after the implementation of an education intervention was used. Twenty nine nurses, doctors and allied health personnel employed at the study site participated in the study. The educational intervention consisted of an electronic presentation plus simulated video recorded exemplars of clinical handover. Outcome measures were the efficacy of the education intervention on the confidence of practitioners using the iSoBAR handover tool. Participants' understanding of the iSoBAR tool using Mann-Whitney U test was 2.54 pre intervention and 4.32 post-intervention. Confidence in using the tool also increased post educational intervention from 2.7 (pre-intervention) to 4.07 (post intervention). Focus groups identified several factors relating to the implementation of iSoBAR, creating two dominant themes: challenges concerning patient factors and change management processes and systems. Opportunities were identified: Practice enhancement, patient centred care, professional practice, and grassroots initiatives. The use of an interprofessional educational program increased the confidence and understanding of a range of health care practitioners when using the clinical handover tool iSoBAR. PMID- 30273804 TI - The effectiveness of short answers test papers in evaluating academic nursing programs: A review of the literature. AB - Short answer tests (SAT) are an assessment that examines nursing students' knowledge and can be used to evaluate expectations for student educational success. The purpose of this literature review is to combine the best available evidence as to whether short answer test papers meet nursing facility curricula learning outcomes. A literature review was performed consisting of data bases which included; ERIC, SCOPUS, CINAHL MEDLINE, COCHRANE LIBRARY and JOHANNA BIGGS INSTITUTE (JBI). The following keywords were used: Short answer test, written assessment, quiz, organisations, university, higher degree education, tertiary education, nursing, perceptions, attitude, opinions, thoughts, feeling and belief. The majority of studies demonstrated that short answer tests equip nursing students with the knowledge and critical thinking skills for the clinical setting. Three major themes were identified: the effects of increasing class sizes; authenticity and the validity of short answer tests. Short answer tests are commonly used in undergraduate nursing programs to evaluate students' level of knowledge which consists of their ability to critically analyse and problem solve. To maintain authenticity and validity of an assessment, there is a need for an evidence-based approach to their design to meet the core learning objectives within the curriculum.

PMID- 30273806 TI - Direct investigation of charge transfer in neurons by electrostatic force microscopy. AB - Charge transfer plays fundamental roles in information transmission in cells, especially in neurons. To date, direct observation of charge propagation in neurons at nanometer level has not been achieved yet. Herein, a combined charge injection and Electrostatic Force Microscopy (EFM) detection approach is applied to directly study charge propagation and distribution at nanometer resolution in spines and synapses of hippocampal neurons. Charge density, charge mobility and membrane potential in neural signal transmission process through the spines of axons and dendrites of hippocampal neurons were investigated quantitatively. Postsynaptic densities (PSD) in spines of axons and dendrites were revealed and studied. The methods and results from present work provide insights into physiological activities and processes related with electrical properties in nervous system and other biological samples. PMID- 30273807 TI - A vibration analysis of a cracked micro-cantilever in an atomic force microscope by using transfer matrix method. AB - In this paper, the effects of crack size and its location have been investigated on the free vibration of an atomic force microscopy (AFM) cantilever applying transfer matrix method. By modeling the crack as a torsional spring and considering the boundary conditions at the contact point with sample's surface, the AFM cantilever vibration behavior has been formulated. Afterwards, the characteristic equation has been derived applying the transfer matrix. At the end, the effects of crack size and its location have been investigated on the flexural resonant frequency and sensitivity of the AFM cantilever. The results indicate that the frequency and sensitivity would be maximum when the crack is approximately in the middle of the cantilever. Growing the crack size can result in the variations of either resonant frequency or sensitivity especially for more stiff samples. PMID- 30273808 TI - Degradation of acetaminophen with ferrous/copperoxide activate persulfate: Synergism of iron and copper. AB - To enhance the advanced oxidation process based on persulfate, CuO was introduced into the Fe2+/PS system to achieve a synergistic effect between Fe and Cu. Results showed that Fe2+ was able to adsorb onto the CuO surface to form Fe(II) and further reduced Cu(II) into Cu(I), which can further release into the solution to participate in oxidation reactions. In this case, SO4.- can be generated via Fe2+ and Cu+ reactions with PS and .OH from Cu+ reaction with dissolved oxygen (DO). The degradation efficiency of APAP was studied under the optimal condition (initial pH 6.5, PS = 0.8 g L-1, Fe2+ = 0.7 mM, CuO = 0.3 g L 1), and the results indicated that the Fe2+/CuO/PS system can achieve a higher degradation rate of APAP (92% within 90 min) rather than Fe2+/PS and CuO/PS system (79% and 10%). Quenching experiment was performed to verify the active radicals in the Fe2+/CuO/PS system. Sulfate and hydroxyl radicals were generated in the Fe2+/CuO/PS system. Besides, some critical factors, such as Fe2+ concentration, catalyst dosage, PS concentration, initial pH (buffers and nonbuffers), and dissolved oxygen were evaluated in bath experiments. Results indicated that dissolved oxygen was essential in the Fe2+/CuO/PS system. APAP degradation experiments were conducted in surface water, and the intermediates were detected via GC-MS. The results indicated that the Fe2+/CuO/PS system is effective in the treatment of APAP in natural waters.

AB - For over a century, anaerobic digestion has been a key technology in stabilizing organic waste streams, while at the same time enabling the recovery of energy. The anticipated transition to a bio-based economy will only increase the quantity and diversity of organic waste streams to be treated, and, at the same time, increase the demand for additional and effective resource recovery schemes for nutrients and organic matter. The performance of anaerobic digestion can be supported and enhanced by (bio)electrochemical systems in a wide variety of hybrid technologies. Here, the possible benefits of combining anaerobic digestion with (bio)electrochemical systems were reviewed in terms of (1) process monitoring, control, and stabilization, (2) nutrient recovery, (3) effluent polishing, and (4) biogas upgrading. The interaction between microorganisms and electrodes with respect to niche creation is discussed, and the potential impact of this interaction on process performance is evaluated. The strength of combining anaerobic digestion with (bio)electrochemical technologies resides in the complementary character of both technologies, and this perspective was used to distinguish transient trends from schemes with potential for full-scale application. This is supported by an operational costs assessment, showing that the economic potential of combining anaerobic digestion with a (bio)electrochemical system is highly case-specific, and strongly depends on engineering challenges with respect to full-scale applications. PMID- 30273810 TI - The relationship between heparanase levels, thrombus burden and thromboembolism in patients receiving unfractionated heparin treatment for prosthetic valve thrombosis. AB - INTRODUCTION: Procoagulant activity of heparanase has been recently described in several arterial and venous thrombotic disorders. In this study, we aimed to investigate the role of heparanase with regard to thrombus burden, thromboembolism, and treatment success with unfractionated heparin (UFH) in patients with prosthetic valve thrombosis (PVT). METHODS: This study enrolled 79 PVT patients who received UFH for PVT and 82 controls. Plasma samples which were collected from patients both at baseline and after the UFH treatment and from controls at baseline only, were tested for heparanase levels by heparanase enzyme linked immunosorbent assay. RESULTS: The PVT group included 18 obstructive and 61 non-obstructive PVT patients who received UFH infusions for a median duration of 15 (7-20) days. The UFH treatment was successful in 37 (46.8%) patients. Baseline heparanase levels were significantly higher in the patient group than in the controls [0.29 (0.21-0.71) vs. 0.25 (0.17-0.33) ng/mL; p = 0.002]. Baseline heparanase levels were significantly higher in obstructive PVT patients. There was a significant increase in heparanase levels after UFH treatment. Post-UFH heparanase levels were higher in patients who experienced treatment failure compared to successfully treated group. Baseline and post-UFH heparanase levels were significantly higher in patients with a thrombus area >=1 cm2 and with a recent history of thromboembolism. CONCLUSIONS: Increased heparanase levels may be one of the esoteric causes for PVT. UFH treatment may trigger an increase in heparanase levels which may affect the treatment success. Increased heparanase levels may be associated with high risk of thromboembolism and increased thrombus burden in PVT patients. PMID- 30273811 TI - Anti-PF4/heparin antibodies are increased in hospitalized patients with bacterial sepsis. AB - Heparin-induced thrombocytopenia (HIT) is caused by antibodies targeting platelet factor 4 (PF4)/heparin complexes. The immune response leading to HIT remains perplexing with many paradoxes. Unlike other drug induced reactions, anti PF4/heparin antibody generation does not follow the classic immunologic response. Research in murine models suggests that that there is close interplay among infection, PF4 and the immune system. We hypothesized there would be a relatively higher prevalence of anti-PF4/heparin antibodies in patients hospitalized for sepsis. We retrospectively examined anti-PF4/heparin antibody testing in 200 such patients. This included patients who had sepsis with bacteremia (n = 57), sepsis with fungemia (n = 7) and sepsis without bacteremia or fungemia (n = 136). For comparison, data from 50 patients without sepsis during the same time period was used. Results confirmed that patients hospitalized with sepsis have higher anti PF4/heparin antibody levels. The groups of patients having sepsis with bacteremia, and sepsis without bacteremia, had significantly higher OD than the control group without sepsis (p < 0.05). There was no significant difference between Gram negative and Gram positive bacteremia and antibody levels. This suggests that bacterial cell wall components of both classes have similar antigenicity. Interestingly, patients who had sepsis with fungemia had much lower antibody levels compared to those with sepsis and bacteremia, and sepsis without bacteremia or fungemia. Despite the small sample size for fungemia, this difference trended strongly towards statistical significance (p = 0.05). It would be interesting to investigate this further in a larger study or using in vitro studies. In summary, there is an increased prevalence of anti-PF4/heparin antibodies in patients hospitalized with bacterial but not fungal sepsis. These results indicate that bacterial infection has a role to play in preimmunization leading to anti-PF4/heparin antibody generation.

AB - The treatment armamentarium for patients with metastatic melanoma has increased substantially over the past decade with the regulatory approval of targeted BRAF + MEK inhibitors and immune checkpoint inhibitors, which have vastly improved long-term outcomes. Recently, these advances have been rapidly translated to the high-risk adjuvant setting. Primary and acquired resistance to both immune and molecularly targeted agents, however, remains a challenge. Therefore, biomarkers predictive of response to therapy that can be assessed prior to initiation of treatment and early during the course of therapy are critical. Equally important is on-treatment biomarker monitoring that may predict the likelihood of treatment failure and disease relapse. This review will summarize recent advances in the understanding of biomarkers for patients with advanced melanoma, emphasizing emerging baseline predictive factors and on-treatment monitoring of biomarkers that aim to establish truly personalized treatment. PMID- 30273813 TI - Socioeconomic trends in school bullying among Finnish adolescents from 2000 to 2015. AB - Bullying at school has far-reaching impacts on adolescent well-being and health. The aim of this study was to examine trends in bullying at school according to socioeconomic adversities among Finnish adolescents from 2000 to 2015. A population-based school survey was conducted biennially among 14-16-year-old Finns between 2000 and 2015 (n = 761,278). Distributions for bullying, being bullied and socioeconomic adversities were calculated. Associations between bullying involvement, time and socioeconomic adversities were studied using binomial logistic regression with results shown by odds ratios with 95% confidence intervals. At the population level, the likelihoods of bullying and being bullied varied only slightly between 2000 and 2015. Bullying and being bullied were associated with socioeconomic adversities (low parental education, not living with both parents and parental unemployment in the past year). Unlike in the general population, the likelihoods of bullying and being bullied increased markedly among adolescents with most socioeconomic adversities. The increased socioeconomic differences in bullying involvement observed in this study add to the mounting evidence of polarization of adolescent health and well being. Socioeconomic adversities should be considered in the prevention of bullying at school. In addition, socio-political measures are needed to decrease socioeconomic inequalities among Finnish adolescents. PMID- 30273814 TI - Exposure to domestic violence as abuse and neglect: Constructions of child maltreatment in daily practice. AB - Research finds that exposure to domestic violence can adversely affect the emotional, behavioral, and physical health of children. These effects have led some child advocates and policymakers in the United States to conclude that child exposure to domestic violence (CEDV) is a type of child maltreatment warranting state intervention. However, few states have defined CEDV as a type of maltreatment in statute and little is known about how child welfare agencies respond to allegations of CEDV in the absence of other safety threats. This study considers that CEDV itself might prompt an initial child welfare referral and may be construed by workers as a type of statutory maltreatment. Using a random sample (n = 295) of case records, this study analyzed one large child welfare agency's response to referrals alleging CEDV between 2011 and 2012. Findings indicate that CEDV itself did trigger investigation. At time of referral, workers used statutory maltreatment typologies to construe alleged CEDV as a type of maltreatment; however, CEDV was not consistently construed as a safety threat and few allegations were substantiated. Instead most families were referred to community-based domestic violence services. Findings indicate that CEDV was not consistently construed as a type of statutory maltreatment and infrequently resulted in ongoing child welfare services. Findings suggest that training is needed to help workers better assess CEDV-related safety threats. Findings also raise questions about what types of interventions are needed to protect children from domestic violence and which types of agencies are best positioned to deliver those interventions. PMID- 30273815 TI - Patterns of adversity and pathways to health among White, Black, and Latinx youth. AB - Research has demonstrated the negative impact of Adverse Childhood Experiences (ACEs) on long-term trajectories of mental and physical health. Yet existing literature on this topic is limited in its understanding of outcomes among youth samples, optimal measurement items and methods, and differences in adverse experiences across race/ethnicity. The current study used a person-centered approach to measure ACEs and their impact on youth health outcomes across three different racial/ethnic groups from a large national database. Patterns of exposure to adverse experiences among Black, Latinx, and White youth (N = 30,668, ages 12-17) were determined empirically using latent class analysis (LCA). Significant differences in class membership by demographic indicators (age, household income, sex) and concurrent health outcomes were identified. Different models emerged for Black (2 classes), Latinx (3 classes), and White youth (3 classes). Older and lower-income youth were more likely to have experienced adversities, but there were no differences in adversity likelihood by sex. Additionally, racial/ethnic minority youth were at greater risk of experiencing higher levels of adversity, poverty, and poor health when compared to their White counterparts. Rather than occuring in meaningful clusters, adverse experiences among youth reflected a cumulative risk model such that classes were defined by the overall intensity of adverse experiences (i.e., low, moderate, high). Findings provide greater knowledge regarding the relationship between ACEs and health and future research directions to inform more targeted and culturally appropriate screening, prevention, and intervention programs. PMID- 30273816 TI - Capillary electrophoresis method for the determination of (R)-dapoxetine, (3S)-3 (dimethylamino)-3-phenyl-1-propanol, (S)-3-amino-3-phenyl-1-propanol and 1 naphthol as impurities of dapoxetine hydrochloride. AB - A capillary electrophoresis method was developed and validated for the determination of the purity of dapoxetine with regard to the related substances (3S)-3-amino-3-phenylpropan-1-ol, (3S)-3-(dimethylamino)-3-phenylpropan-1-ol, 1 naphthol and the enantiomer (R)-dapoxetine. The separation was based on a dual selector system, which was optimized by a fractional factorial resolution V + design followed by a central composite face centered design with star distance 1 and Monte Carlo simulations for defining the design space. The optimized background electrolyte consisted of a 50 mM sodium phosphate buffer, pH 6.3, containing 45 mg/mL sulfated gamma-cyclodextrin and 40.2 mg/mL 2,6-dimethyl-beta cyclodextrin. Separations were carried out in a 23.5/32 cm, 50 MUm fused-silica capillary employing a separation voltage of 9 kV at 15 degrees C. Following robustness testing using a Plackett-Burman design the method was validated according to the International Council on Harmonization guideline Q2(R1) in the range of 0.05-1.0% relative to the dapoxetine concentration. The method was applied to the analysis of drug substance and a commercial tablet. Data regarding the enantiomeric purity of dapoxetine obtained by the capillary electrophoresis assay were comparable to the data obtained by an enantioselective HPLC method. PMID- 30273818 TI - Development and validation of a method using ultra performance liquid chromatography coupled to tandem mass spectrometry for determination of zoledronic acid concentration in human bone. AB - A method for the extraction and quantification of zoledronic acid (ZA) from human bone was set up and validated. This method allowed the quantification of ZA from jawbone sequestrations of patients affected by bisphosphonate-related osteonecrosis of the jaw (BRONJ) associated with ZA treatment. The analyte was extracted from the bone tissues with phosphoric acid and derivatized using trimethylsilyl diazomethane (TMS-DAM). ZA tetramethyl phosphonate was then quantified by liquid chromatography coupled to tandem mass spectrometry (LC MS/MS), showing high accuracy, repeatability and selectivity. Lower limits of quantification and detection (LLOQ and LLQD) were 3.4 ng/mL and 1 ng/mg, respectively. This study fully described the analytical process for the determination of ZA in human bone sequestrations, representing a pivotal step for further biomedical research on ZA and BRONJ. PMID- 30273817 TI - Development of new methods for determination of bilirubin. AB - The ever-increasing demand for a sensitive, rapid and reliable method for determination of serum bilirubin level has been inciting the interest of the researchers to develop new methods for both laboratory set up and point of care applications. These efforts embrace measurement of different forms of bilirubin, such as, unconjugated (free and albumin bound) bilirubin, conjugated (direct) bilirubin, and total (both conjugated and unconjugated) bilirubin in the serum that may provide critical information useful for diagnosis of many diseases and metabolic disorders. Herein, an effort has been made to provide a broad overview on the subject starting from the conventional spectroscopy based analytical methods widely practiced in the laboratory setup along with the sophisticated instrument based sensitive methods suitable for determination of different forms of bilirubin to various portable low cost systems applicable in point of care (POC) settings. In all these discussions emphasis is given on the novel methods and techniques bearing potential to measure the bilirubin level in biological samples reliably with less technical complexity and cost. We expect that this review will serve as a ready reference for the researchers and clinical professionals working on the subject and allied fields. PMID- 30273819 TI - Effects of a leucine-enriched amino acid supplement on muscle mass, muscle strength, and physical function in post-stroke patients with sarcopenia: A randomized controlled trial. AB - OBJECTIVES: The aim of this study was to investigate the effects of a leucine enriched amino acid supplement on muscle mass, muscle strength, and physical function in post-stroke patients with sarcopenia. METHODS: We conducted an eight wk, two-parallel group intervention, randomized controlled, blinded outcome assessment among 44 post-stroke older patients with sarcopenia. Sarcopenia was defined as a loss of skeletal muscle mass and decreased muscle strength according to the Asian Working Group for Sarcopenia criteria. The intervention group (n = 21) received a leucine-enriched amino acid supplement; the control group (n = 23) did not. Both groups performed low-intensity resistance training in addition to a post-stroke rehabilitation program. A primary outcome of physical function by using the motor domain of Functional Independence Measure (FIM), and secondary outcomes of appendicular muscle mass (skeletal muscle mass index [SMI]) measured via bioelectrical impedance analysis and muscle strength as handgrip strength were measured at baseline and at the end of the intervention. RESULTS: The FIM score increased significantly in both groups over time (P < 0.01), with significantly greater improvement in the intervention group than in the control group (P < 0.045). Handgrip strength also increased significantly over time (P <0.05), with significantly greater improvement in the intervention group (P < 0.01). The SMI increased significantly in the intervention group but not in the control group over time, with significantly greater improvement in the intervention group (median estimated difference, 0.50 kg/m2; 95% confidence interval, 0.01-2.11). CONCLUSIONS: We demonstrated that an eight-wk intervention consisting of a leucine-enriched amino acid supplementation and low-intensity resistance training increased muscle mass, strength, and physical function in post-stroke patients with sarcopenia. PMID- 30273820 TI - Development, validity, and reproducibility of a semiquantitative food frequency questionnaire for the assessment of antioxidant vitamins intake in Lebanon. AB - OBJECTIVES: The growing interest in the possible role of antioxidant vitamins in many pathologies makes the methods of evaluating the intakes of these vitamins necessary. The food frequency questionnaire is the most widely used tool in epidemiologic studies and large-scale surveys to assess long-term nutritional exposure and to determine the usual intake of specific foods or nutrients. The aims of this study were to develop and investigate the validity and reproducibility of a semiquantitative food frequency questionnaire (SQFFQ) to evaluate the antioxidant vitamins intake in the Lebanese population and for use in clinical trials. METHODS: An SQFFQ draft was built with the major sources of vitamins with antioxidant properties initially selected from food that have the higher percentages of the daily value of vitamins A, C, and E; listed in the US Department of Agriculture tables. We used food intake data that were available through a 24-h dietary recall (3 weekdays and 1 weekend day) among a subsample of 50 participants to complete the SQFFQ. We sought the major sources of the most frequently reported antioxidant vitamins, portion sizes, and percentages of the daily value of the major sources of these vitamins (developed by the US Department of Agriculture) to build a 34-item SQFFQ. The consumption frequency was coded as daily, weekly, monthly, or occasionally and one to three times or more. Five hundred Lebanese participants (the previous 50 who provided the 24 h dietary recall, along with 450 new participants) completed the questionnaire, whereas only 50 and 42 were accepted to be enrolled in the validity and reproducibility studies, respectively. To assess validity, the questionnaire was compared with the 24-h dietary recall performed on a subsample of 50 participants who already completed the SQFFQ. The reproducibility was assessed by comparing baseline SQFFQ with a second administration of the SQFFQ 3 to 5 wk later at the same dietetic clinic. RESULTS: The means of daily consumption of vitamins A, C, and E based on the SQFFQ and the 24 h data were as follows: Vitamin A: 252.5 +/- SD 958.9 versus 242.6 +/- SD 580.5 mcg of retinol activity equivalents (ug RAE), Vitamin C: 86.5 +/- SD 59.9 versus 85.5 +/- SD 56.2ug, and Vitamin E: 17 +/- SD 7.2 versus 17.1 +/- SD 7.9ug. The Pearson correlation coefficients of the three vitamins between dietary intake estimates derived from the SQFFQ and 24-h data were, respectively, r = 0.83, 0.98, and 0.9; they were highly significant at P < 0.001. One sample t tests and Bland-Altman plots confirmed this validity. The reproducibility of the SQFFQ was assessed using the Cronbach alpha index that measures reliability between different components (for vitamin A: 0.994, vitamin C: 0.998, and vitamin E: 0.975). The correlation matrix (interitem correlation) showed that all elements were highly correlated (r > 0.4) and even close to 1 (for vitamin A = 0.989, vitamin C = 0.995, and vitamin E = 0.95). CONCLUSIONS: In this study, we described the development of an SQFFQ. Based on the results, we found the SQFFQ to be valid and reproducible to assess intake of antioxidant vitamins in Lebanese adults.. PMID- 30273821 TI - Peripheral interleukin-6 levels and working memory in non-obese adults: A post hoc analysis from the CALERIE study. AB - OBJECTIVES: This analysis aimed to investigate the association among interleukin 6 (IL-6) levels, caloric intake, and working memory and to explore the potential mediators of these associations using the public dataset from the Comprehensive Assessment of Long-Term Effects of Reducing Intake of Energy (CALERIE) clinical trial. METHODS: The CALERIE study was designed to evaluate the effects of 2 y of prolonged caloric restriction in humans. Individuals were randomized to caloric restriction (CR; n = 145) or an ad libitum diet (AL; n = 75) for 2 y. The outcome measures used herein were spatial working memory tests (i.e., total number of errors and strategy). Generalized estimating equations were used to assess the effects of treatment, time, and potential moderators (e.g., sleep and physical activities). RESULTS: At baseline, there was an effect of hours of sleep, alcohol intake, and physical activities (i.e., mean total metabolic equivalent of task hours per day [MET-hours/day]) on IL-6 levels. The association between IL-6 and energy intake was moderated by MET-hours/day. The longitudinal analysis indicated that there was an effect of time, but not of treatment, on IL-6 levels, with decreasing values in both the CR and AL groups. Changes in IL-6 levels were associated with changes in working memory performance, but there were no between group (i.e., CR vs. AL) differences. CONCLUSIONS: We observed an association between changes in IL-6 levels and improvement in spatial working memory tests. IL-6 was associated with higher caloric consumption, poorer sleep quality, and lower levels of physical activity. PMID- 30273822 TI - Ingestion of soy protein isolate attenuates eccentric contraction-induced force depression and muscle proteolysis via inhibition of calpain-1 activation in rat fast-twitch skeletal muscle. AB - OBJECTIVE: Eccentric contraction (ECC) is a contraction in which skeletal muscles are stretched while contracting. The aim of this study was to determine how ingestion of soy protein isolate (SPI) or animal-based proteins affect force deficit, calpain activation, and proteolysis of calcium ion (Ca2+)-regulatory proteins in rat fast-twitch muscles subjected to ECC. METHODS: In the first experiment, male Wistar rats were randomly assigned to a control and an SPI group, which were fed a 20% casein and a 20% SPI diet, respectively, for 28 d before the ECC protocol. Anterior crural muscles underwent 200 repeated ECCs and were excised 3 d later. In the second experiment, half of the SPI rats were given water containing NG-nitro-l-arginine-methyl ester (L-NAME), an inhibitor of nitric oxide synthase, for 3 d of recovery after ECC. RESULTS: SPI ingestion attenuated ECC-induced force deficit, proteolysis of Ca2+-regulatory proteins, and autolysis of calpain-1. Co-ingestion of L-NAME inhibited SPI-associated increases in nitrite and nitrate levels and negated the force recovery effects of SPI. CONCLUSION: These results suggest that SPI ingestion inhibits ECC-elicited force deficit and proteolysis of Ca2+ regulatory proteins, which is caused by inhibited activation of calpain-1 via increased nitric oxideproduction. PMID- 30273823 TI - Dietary intake of magnesium and the risk of epilepsy in middle-aged and older Finnish men: A 22-year follow-up study in a general population. AB - OBJECTIVES: Magnesium may play an important role in the prevention or treatment of epilepsy. We aimed to examine the association between dietary intake of magnesium and the incidence of epilepsy in middle-aged Finnish men in a prospective setting. As a secondary analysis, we also considered a possible association between dietary intake of magnesium and inflammation in subjects with epilepsy. METHODS: The study included 2442 men, ages 42 to 60 y, from the prospective Kuopio Ischaemic Heart Disease Risk Factor Study who were free of epilepsy at baseline between 1984 and 1989. Dietary intake of magnesium was assessed with a 4-d food record. The hospital discharge diagnosis of epilepsy was used as an outcome variable. RESULTS: During the average follow-up period of 22.4 y, 74 men (3%) developed epilepsy. Those who followed the recommended dietary intake (>350 mg/d) of magnesium had a lower risk of epilepsy (hazard ratio [HR]: 0.52; confidence interval [CI], 0.28-0.99; P = 0.045) after multivariate adjustments. However, the risk was not significant after adjustment for C reactive protein (CRP). We also found that CRP concentration was directly associated with the risk of epilepsy (HR: 1.24; CI, 1.00-1.54; P = 0.048). This association was attenuated after adjustment for dietary intake of magnesium and no longer significantly associated with the risk of epilepsy (HR: 1.22; CI, 0.99 1.52; P = 0.07). CONCLUSIONS: A higher dietary intake of magnesium was associated with lower incident epilepsy, and this association was slightly mediated by CRP. Further studies are required to identify the potential mechanisms. PMID- 30273824 TI - Sharing data on DNA transfer, persistence, prevalence and recovery: Arguments for harmonization and standardization. AB - Sharing data between forensic scientists on DNA transfer, persistence, prevalence and recovery (TPPR) is crucial to advance the understanding of these issues in the criminal justice community. We present the results of a collaborative exercise on reporting forensic genetics findings given activity level propositions. This exercise outlined differences in the methodology that was applied by the participating laboratories, as well as limitations to the use of published data on DNA TPPR. We demonstrate how publication of experimental results in scientific journals can be further improved to allow for an adequate use of these data. Steps that can be taken to share and use these data for research and casework purposes are outlined, and the prospects for future sharing of data through publicly accessible databases are discussed. This paper also explores potential avenues to proceed with implementation and is intended to fuel the discussion on sharing data pertaining to DNA TPPR issues. It is further suggested that international standardization and harmonization on these topics will benefit the forensic DNA community as it has been achieved in the past with the harmonization of STR typing systems. PMID- 30273825 TI - Simultaneous application of predictive model and least cost formulation can substantially benefit biorefineries outside Corn Belt in United States: A case study in Florida. AB - Previously, a predictive model was developed to identify optimal blends of expensive high-quality and cheaper low-quality feedstocks for a given geographical location that can deliver high sugar yields. In this study, the optimal process conditions were tested for application at commercially-relevant higher biomass loadings. We observed lower sugar yields but 100% conversion to ethanol from a blend that contained only 20% high-quality feedstock. The impact of applying this predictive model simultaneously with least cost formulation model for a biorefinery location outside of the US Corn Belt in Lee County, Florida was investigated. A blend ratio of 0.30 EC, 0.45 SG, and 0.25 CS in Lee County was necessary to produce sugars at high yields and ethanol at a capacity of 50 MMGY. This work demonstrates utility in applying predictive model and LCF to reduce feedstock costs and supply chain risks while optimizing for product yields. PMID- 30273826 TI - The changes in carbon, nitrogen components and humic substances during organic inorganic aerobic co-composting. AB - In this article, the changes in carbon, nitrogen components, and humic substances during organic-inorganic aerobic co-composting, with adding biochar as an additive or not, were studied. Results showed that adding a certain amount of inorganic fertilizers had no adverse effects on the compost fermentation process. Biochar enhanced the temperature, pH, oxygen content in the compost piles and ultimately hastened the fermentation process. Biochar contributed to the decomposition of hemicellulose, cellulose, lignin and promoted compost humification. Adding biochar increased the contents of acid hydrolysis nitrogen, amino acid nitrogen, amino sugar nitrogen, unidentified organic nitrogen and decreased the content of ammonia organic nitrogen thus improved nitrogen transformation and reduced nitrogen loss. The addition of biochar increased the nutrients contents in mature composts. The amendment of 10-15% biochar by weight as an additive would be optimum for the co-composting of organic-inorganic materials. These results contributed to produce value-added composting fertilizers. PMID- 30273827 TI - Co-metabolic enhancement of 1H-1,2,4-triazole biodegradation through nitrification. AB - Due to highly recalcitrant nature of 1H-1,2,4-triazole (TZ), the conventional biological process is quite ineffective for TZ removal from wastewater. In this study, co-metabolic enhancement of TZ biodegradation through nitrification was investigated in an activated sludge reactor. The link between enhanced TZ degradation and nitrification was established through highly efficient removal of TZ, TOC as well as dissolved organic matter with the supplement of NH4+. A new co metabolic degradation pathway of TZ was proposed based on the identification of five co-metabolic intermediates, including 2,4-dihydro-[1,2,4]triazol-3-one and [1,2,4]triazolidine-3,5-dione. High-throughput sequencing analysis suggested the significant improvement of microbial community in the co-metabolic system in terms of richness, abundance and uniformity. Functional species related to nitrification and biodegradation was enriched with the supplement of NH4+, confirming the key role of nitrification. This study demonstrated that nitrification-assisted co-metabolism had a promising potential for the removal of recalcitrant contaminants such as TZ from wastewater. PMID- 30273828 TI - Characteristics of acidogenic fermentation for volatile fatty acid production from food waste at high concentrations of NaCl. AB - This study explored the effects of NaCl on volatile fatty acid (VFA) production from food waste by acidogenic fermentation. The production and composition of VFAs, and the microbial community in acidogenic fermentation were investigated at four different NaCl concentrations: 10, 30, 50, and 70 g/L, and at 0 g/L (control). The highest VFA production was 0.542 g/g dry weight of food waste at 10 g/L NaCl, and about 23% lower but still high at 70 g/L NaCl. Interestingly, as NaCl concentration increased, the residence time of lactic acid in the reactor increased, and the maximum production also increased. The type of acidogenic fermentation also changed from butyric acid to propionic acid as the NaCl concentration increased. Microbial community analysis showed that a large number of propionibacteria were present at the end of fermentation, indicating their high tolerance to NaCl. PMID- 30273829 TI - Early disruption of parvalbumin expression and perineuronal nets in the hippocampus of the Tg2576 mouse model of Alzheimer's disease can be rescued by enriched environment. AB - Recent findings show that parvalbumin (PV) interneuron function is impaired in Alzheimer's disease (AD), and that this impairment in PV function can be linked to network dysfunction and memory deficits. PV cells are often associated with a specific extracellular matrix, the perineuronal net (PNN). PNNs are believed to protect PV cell integrity, and whether the amyloidopathy affects PNNs remains unclear. Here, we evaluated the number of PV cells with and without PNNs in the hippocampus of the Tg2576 mouse model of AD at different stages of the disease. We show a deficit of PV+ and/or PV+/PNN+ cells in the areas CA1, CA2, and CA3 in Tg2576 as young as 3 months of age. Importantly, transient exposure to an enriched environment, which has proven long-lasting beneficial effects on memory in AD subjects, rescues the PV/PNN cell number deficits. We conclude that cognitive improvements induced by enriched environment in AD mouse models could be supported by a remodeling of hippocampal PV cell network and their PNNs. PMID- 30273830 TI - Sleep and circadian abnormalities precede cognitive deficits in R521C FUS knockin rats. AB - Mutations in fused in sarcoma (Fus) cause familial amyotrophic lateral sclerosis (ALS) and occasionally frontotemporal dementia. Here we report the establishment and characterization of a novel knockin (KI) rat model expressing a Fus point mutation (R521C) via CRISPR/Cas9. The mutant animals developed adult-onset learning and memory behavioral deficits, with reduced spine density in hippocampal neurons. Remarkably, sleep-wake cycle and circadian abnormalities preceded the onset of cognitive deficit. RNA-seq study further demonstrated altered expression of some key sleep and circadian regulators, such as orexin/hypocretin receptor type 2 and casein kinase 1 epsilon, in the mutant rats. Therefore, we have established a rodent model expressing physiological level of a pathogenic mutant FUS, and we found cognitive impairment as a main behavioral deficit at mid age. Furthermore, we have revealed a new role of FUS in sleep and circadian regulation and demonstrated that functional change in FUS could cause sleep-wake and circadian disturbance as early symptoms.

AB - Assessment of respiratory activity in pediatric intensive care unit allows a comprehensive view of the patient's condition. This allows the identification of high-risk cases for prompt and appropriate medical treatment. Numerous research works on respiration monitoring have been conducted in recent years. However, most of them are unsuitable for clinical environment or require physical contact with the patient, which limits their efficiency. In this paper, we present a novel system for measuring the breathing pattern based on a computer vision method and contactless design. Our 3D imaging system is specifically designed for pediatric intensive care environment, which distinguishes it from the other imaging methods. Indeed, previous works are mostly limited to the use of conventional video acquisition devices, in addition to not considering the constraints imposed by intensive care environment. The proposed system uses depth information captured by two (Red Green Blue-Depth) RGB-D cameras at different view angles, by considering the intensive care unit constraints. Depth information is then exploited to reconstruct a 3D surface of a patient's torso with high temporal and spatial resolution and large spatial coverage. Our system captures the motion information for the top of the torso surface as well as for its both lateral sides. For each reconstruction, the volume is estimated through a recursive subdivision of the 3D space into cubic unit elements. The volume change is then calculated through a subtraction technique between successive reconstructions. We tested our system in the pediatric intensive care unit of the Sainte-Justine university hospital center, where it was compared to the gold standard method currently used in pediatric intensive care units. The performed experiments showed a very high accuracy and precision of the proposed imaging system in estimating respiratory rate and tidal volume.

AB - Alzheimer's disease is a neurodegenerative process leading to irreversible mental dysfunctions. To date, diagnosis is established after incurable brain structure alterations. The development of new biomarkers is crucial to perform an early detection of this disease. With the recent improvement of magnetic resonance imaging, numerous methods were proposed to improve computer-aided detection. Among these methods, patch-based grading framework demonstrated state-of-the-art performance. Usually, methods based on this framework use intensity or grey matter maps. However, it has been shown that texture filters improve classification performance in many cases. The aim of this work is to improve performance of patch-based grading framework with the development of a novel texture-based grading method. In this paper, we study the potential of multi directional texture maps extracted with 3D Gabor filters to improve patch-based grading method. We also proposed a novel patch-based fusion scheme to efficiently combine multiple grading maps. To validate our approach, we study the optimal set of filters and compare the proposed method with different fusion schemes. In addition, we also compare our new texture-based grading biomarker with state-of the-art methods. Experiments show an improvement of AD detection and prediction accuracy. Moreover, our method obtains competitive performance with 91.3% of accuracy and 94.6% of area under a curve for AD detection. PMID- 30273833 TI - Bioinspired silica-infiltrated zirconia bilayers: Strength and interfacial bonding. AB - Conventionally veneered zirconia restorations are susceptible to chipping and spalling of the veneering material. The novel translucent zirconias were developed to overcome such issues, although layered zirconia restorations can be re-designed to improve mechanical performance. Thus, the aim of this study was to analyze the strength and structural reliability of zirconia bilayers using conventional (porcelain ceramic under tensile stress) and bioinspired (zirconia under tensile stress) configurations. Sol-gel silica infiltration served as a smooth transition between the zirconia and veneering porcelain. Failure mode and interfacial adhesive mechanism were analyzed using scratch test and interfacial indentation. Bilayered specimens were produced for biaxial flexural testing with Y-TZP and pressed ceramic, which were further divided into four groups (n = 30): Conventional (C), Infiltrated conventional (IC), Bioinspired (B) and Infiltrated bioinspired (IB). The results of biaxial flexural strength tests were analyzed by Weibull analysis (95% CI) for determination of the Weibull modulus (m). The infiltration layer was characterized by XRD and SEM, FEG-SEM and EDS. The bioinspired infiltrated group was the most reliable (m = 9.59), although the fine damage of veneered conventional (conventional) zirconia demonstrated its superior resistance to scratching and debonding. Therefore, the filling of superficial defects by zirconia silicate demonstrated the need for mechanical retention for better porcelain adhesion. PMID- 30273835 TI - Bioengineered stem cell membrane functionalized nanocarriers for therapeutic targeting of severe hindlimb ischemia. AB - Bioengineering strategies to enhance the natural targeting function of nanocarriers would expand their therapeutic applications. Here, we designed bioengineered stem cell membrane-functionalized nanocarriers (BSMNCs) harboring C X-C chemokine receptor type 4 (CXCR4) to achieve robust targeting and also to increase their retention time in ischemic tissue. Stem cell membrane coated nanocarrier (SMNCs) or poly (lactic-co-glycolic acid) (PLGA) nanocarriers (PNCs) and BSMNCs were prepared by functionalizing PNCs with human adipose-derived stem cells (hASCs) membranes and hASCs engineered to overexpress CXCR4-receptor, respectively. The functionalization of PNCs with stem cell membranes derived from hASCs significantly enhance the nanocarrier penetration across endothelial cell barrier compare to PNCs. In addition, stem cell membrane functionalization on PNCs also significantly decreased the nanoparticles uptake in J774 (murine) and THP (human) macrophages respectively from 84% to 76%-29% and 24%. Interestingly, BSMNCs showed much higher level of accumulation in ischemic tissue than SMNCs. Systemic retro-orbital injection of BSMNCs loaded with VEGF into mice with hindlimb ischemia resulted substantially enhancement of blood reperfusion, muscle repair, and limb salvage compared to animals treated with SMNCs loaded with similar concentration of VEGF. The reported strategy could be used to create biocompatible and custom-tailored biomimetic nanoparticles with various hybrid functionalities, which may overcome the limitations of current nanoparticle-based therapeutic and imaging platforms. PMID- 30273834 TI - Spatially controlled assembly of affinity ligand and enzyme cargo enables targeting ferritin nanocarriers to caveolae. AB - One of the goals of nanomedicine is targeted delivery of therapeutic enzymes to the sub-cellular compartments where their action is needed. Endothelial caveolae derived endosomes represent an important yet challenging destination for targeting, in part due to smaller size of the entry aperture of caveolae (ca. 30 50 nm). Here, we designed modular, multi-molecular, ferritin-based nanocarriers with uniform size (20 nm diameter) for easy drug-loading and targeted delivery of enzymatic cargo to these specific vesicles. These nanocarriers targeted to caveolar Plasmalemmal Vesicle-Associated Protein (Plvap) deliver superoxide dismutase (SOD) into endosomes in endothelial cells, the specific site of influx of superoxide mediating by such pro-inflammatory signaling as some cytokines and lipopolysaccharide (LPS). Cell studies showed efficient internalization of Plvap targeted SOD-loaded nanocarriers followed by dissociation from caveolin containing vesicles and intracellular transport to endosomes. The nanocarriers had a profound protective anti-inflammatory effect in an animal model of LPS induced inflammation, in agreement with the characteristics of their endothelial uptake and intracellular transport, indicating that these novel, targeted nanocarriers provide an advantageous platform for caveolae-dependent delivery of biotherapeutics. PMID- 30273836 TI - Pentamethinium salts as ligands for cancer: Sulfated polysaccharide co-receptors as possible therapeutic target. AB - A series of pentamethinium salts with benzothiazolium and indolium side units comprising one or two positive charges were designed and synthesized to determine the relationships among the molecular structure, charge density, affinity to sulfated polysaccharides, and biological activity. Firstly, it was found that the affinity of the pentamethinium salts to sulfated polysaccharides correlated with their biological activity. Secondly, the side heteroaromates displayed a strong effect on the cytotoxicity and selectivity towards cancer cells. Finally, doubly charged pentamethinium salts possessing benzothiazolium side units exhibited remarkably high efficacy against a taxol-resistant cancer cell line. PMID- 30273837 TI - Pharmacokinetics, tissue distribution and plasma protein binding study of SM-1, a novel PAC-1 derivative. AB - As a PAC-1 derivative, SM-1 exhibts a promising antitumour property. To better understand the relationship between the drug concentrations and pharmacological effects, both liquid chromatography coupled with tandem mass spectrometry and high performance liquid chromatography methods were developed and validated in the work. Those methods were then applied to the pharmacokinetics (PK), tissue distribution and plasma protein binding (PPB) studies of SM-1. As a results, the proposed methods were demonstrated to be accurate, precise and stable for the analysis of the SM-1 in plasma and tissue samples. Meanwhile, the PK parameters of SM-1 showed that SM-1 had good PK properties. SM-1 had good absorption in the body, with 59.01% of the absolute bioavailability in rats and 55.63% of that in dogs. SM-1 rapidly distributed to all tissues, with the highest distribution in the lung and less in the brain and muscle. The PPB rates in rat plasma, dog plasma, and human plasma were 91.1%, 91.2%, and 90.7%, respectively. These good PK properties will contribute SM-1 to be a promising anti-tumour candidate. These results also provide insights into the further pharmacological investigation of SM-1. PMID- 30273838 TI - Peak window correlation method for drug screening using Raman spectroscopy. AB - Modern portable and hand-held Raman spectrometers that recently have become widespread in drug quality screening have good reproducibility and are able to detect small concentrations of substances in mixtures of several components or distinguish compounds similar in structure and having minimal differences in spectrum with appropriate mathematical processing methods. Among other spectrum comparison approaches, the peak search at their location is the most important task of spectral imaging of the studied samples. In this work, the Raman spectra of liquid drugs involved in the governmental non-destructive quality screening program performed by 8 mobile laboratories equipped with Raman spectrometers with uncooled detector and a 532 nm laser were compared with reference sample spectra using the peak windows correlation (PWC) algorithm developed in this work by authors. The proposed method provides accurate identification, detection of composition changes, and presence of foreign components in drugs formulations even if their contribution to the overall signal is negligible. The spectral correlation method called hit-quality index (HQI) method conventionally used for such portable spectrometers was specified as comparative method. PMID- 30273839 TI - Lysosomal exocytosis of ATP is coupled to P2Y2 receptor in marginal cells in the stria vascular in neonatal rats. AB - Adenosine triphosphate (ATP) is stored as lysosomal vesicles in marginal cells of the stria vascular in neonatal rats, but the mechanisms of ATP release are unclear. Primary cultures of marginal cells from 1-day-old Sprague-Dawley rats were established. P2Y2 receptor and inositol 1,4,5-trisphosphate (IP3) receptor were immunolabelled in marginal cells of the stria vascular. We found that 30 MUM ATP and 30 MUM uridine triphosphate (UTP) evoked comparable significant increases in the intracellular Ca2+ concentration ([Ca2+]i) in the absence of extracellular Ca2+, whereas the response was suppressed by 100 MUM suramin, 10 MUM 1-(6-(17beta 3-methoxyester-1,3,5(10)-trien-17-yl)amino)-hexyl)-1H-pyrrole-2,5-dione(U-73122), 100 MUM 2-aminoethoxydiphenyl borate (2-APB) and 5 MUM thapsigargin (TG), thus indicating that ATP coupled with the P2Y2R-PLC-IP3 pathway to evoke Ca2+ release from the endoplasmic reticulum (ER). Incubation with 200 MUM Gly-Phe-beta naphthylamide (GPN) selectively disrupted lysosomes and caused significant increases in [Ca2+]I; this effect was partly inhibited by P2Y2R-PLC-IP3 pathway antagonists. After pre-treatment with 5 MUM TG, [Ca2+]i was significantly lower than that after treatment with P2Y2R-PLC-IP3 pathway antagonists under the same conditions, thus indicating that lysosomal Ca2+ triggers Ca2+ release from ER Ca2+ stores. Baseline [Ca2+]i declined after treatment with the Ca2+ chelator 50 MUM bis-(aminophenolxy) ethane-N,N,N',N'-tetra-acetic acid acetoxyme-thyl ester (BAPTA-AM) and 4 IU/ml apyrase. 30 MUM ATP decrease of the number of quinacrine positive vesicles via lysosome exocytosis, whereas the number of lysosomes did not change. However, lysosome exocytosis was significantly suppressed by pre treatment with 5 MUM vacuolin-1. Release of ATP and beta-hexosaminidase both increased after treatment with 200 MUM GPN and 5 MUM TG, but decreased after incubation with 50 MUM BAPTA-AM, 4 IU/ml apyrase and 5 MUM vacuolin-1. We suggest that ATP triggers Ca2+ release from the ER, thereby contributing to secretion of lysosomal ATP via lysosomal exocytosis. Lysosomal stored Ca2+ triggers Ca2+ release from the ER directly though the IP3 receptors, and lysosomal ATP evokes Ca2+ signals indirectly via the P2Y2R-PLC-IP3 pathway. PMID- 30273841 TI - Patient-reported outcomes in patients with relapsing forms of MS switching to teriflunomide from other disease-modifying therapies: Results from the global Phase 4 Teri-PRO study in routine clinical practice. AB - BACKGROUND: Patient-reported outcomes (PROs) can assist clinicians in understanding the impact of disease-modifying therapy (DMT) on the daily lives of patients with multiple sclerosis (MS). With an increased number of DMTs becoming available, patients are now switching treatments more frequently in clinical practice. The effects of switching DMTs on a patient's daily life and their disease course may be reflected in PROs. The global, multicenter, open-label, phase 4 Teri-PRO study (NCT01895335), which was conducted in routine clinical practice, previously showed statistically and clinically significant increases in patient-reported treatment satisfaction in patients switching to teriflunomide from other DMTs. The impact of switching to teriflunomide from other DMTs on treatment satisfaction and a range of additional PROs was also evaluated. METHODS: Patients with relapsing forms of MS (N = 1000) received teriflunomide for 48 weeks per local labeling. Outcomes assessed in this analysis included treatment satisfaction (as measured by Treatment Satisfaction Questionnaire for Medication [Version 1.4]), disability worsening (as measured using the Expanded Disability Status Scale [EDSS] score, the Patient-Determined Disease Steps scale, and the Multiple Sclerosis Performance Scale), cognition (as measured using the Symbol Digit Modalities Test [SDMT]), treated relapses, quality of life (as measured by the Multiple Sclerosis International Quality of Life [MusiQoL] questionnaire and the Stern Leisure Activity Scale), and safety/tolerability over the course of the study in the subgroup of patients switching to teriflunomide from another DMT (n = 594). RESULTS: Patients reported significant improvements in treatment satisfaction scores following the switch to teriflunomide regardless of the reason for treating with teriflunomide (Global Satisfaction, disease worsening: baseline, 46.0, Week 48, 65.1; convenience: baseline, 57.4, Week 48, 72.4; intolerance: baseline, 50.9, Week 48, 71.1; side effects: baseline, 49.7, Week 48, 67.2; P < 0.0001 in all comparisons). These patients also showed improvement or stability in PROs evaluating disability worsening, cognition, and quality of life (EDSS: baseline, 3.1, Week 48, 3.0; SDMT: baseline, 0.975, Week 48, 0.978; MusiQoL: baseline, 67.5, Week 48, 69.5). The safety and tolerability profile of teriflunomide was consistent with that observed in other teriflunomide clinical trials. CONCLUSION: This analysis of the Teri-PRO study demonstrates the value of switching to teriflunomide from other DMTs in a real-world, clinical practice setting. The high levels of treatment satisfaction associated with teriflunomide in Teri-PRO may lead to improved adherence and thus improved outcomes. PMID- 30273840 TI - Draining the pond and catching the fish: Uncovering the ecosystem of auditory verbal hallucinations. AB - The various models proposed for the mediation of auditory verbal hallucinations (AVH) implicate a considerable number of brain areas and mechanisms. To establish which of those mechanisms are actually involved in the mediation of AVH, we developed a novel method to analyze functional MRI data, which allows for the detection of the full network of mutually interacting brain states, and the identification of those states that are relevant to the mediation of AVH, while applying a minimum number of preconceived assumptions. This method is comparable to the draining of a pond to lay bare the full ecosystem that affects the presence of a particular fish species. We used this model to analyze the fMRI data of 85 psychotic patients experiencing AVH. The data were decomposed into 98 independent components (ICs) representing all major functions active in the brain during scanning. ICs involved in mediating AVH were identified by associating their time series with the hallucination time series as provided by subjects within the scanner. Using graph theory, a network of interacting ICs was created, which was clustered into IC modules. We used causal reasoning software to determine the direction of links in this network, and discover the chain of events that leads to the conscious experience of hallucinations. Hallucinatory activity was linked to three of the seven IC clusters and 11 of the 98 ICs. ICs with the most influential roles in producing AVH-related activity were those within the so-called salience network (comprising the anterior cingulate gyrus, right insula, Broca's homologue, premotor cortex, and supramarginal gyrus). Broca's area and the cerebellar regions were significantly, but more distantly involved in the mediation of AVH. These results support the notion that AVH are largely mediated by the salience network. We therefore propose that the mediation of AVH in the context of schizophrenia spectrum disorders involves the attribution of an excess of negative salience by anterior-cingulate areas to linguistic input from Broca's right homologue, followed by subsequent processing errors in areas further 'downstream' the causal chain of events. We provide a detailed account of the origin of AVH for this patient group, and make suggestions for selective interventions directed at the most relevant brain areas. PMID- 30273842 TI - CSF leukocyte, polykaryocyte, protein and glucose: Their cut-offs of judging whether post-neurosurgical bacterial meningitis has been cured. AB - OBJECT: This paper is aimed to explore a reasonable guideline for distinguishing whether post-neurosurgical bacterial meningitis has completely been cured, so as to avoid the deficient or excessive treatment for post-neurosurgical bacterial meningitis. PATIENTS AND METHODS: We conducted a retrospective analysis of 46 patients who attended General Hospital of Chinese People's Armed Police Force in Beijing, China, from January 1, 2014 to April 30, 2016. The CSF leukocyte, polykaryocyte, protein and glucose had been tested when their antibiotic treatments were empirically stopped. Between the non-relapse and relapse groups, Wilcoxon Rank Sum test was used to compare the differences of CSF leukocyte and polykaryocyte, and t-test was applied to contrast the distinctions of CSF protein and glucose, then, the thresholds of significant items were estimated by ROC curve. RESULTS: The CSF leukocyte counts in non-relapse group are 23.72 +/- 14.12/mm3, which are statistically less than the relapse group's (47.00 +/- 1.00/mm3, P = 0.014), so does the CSF polykaryocyte counts (1.74 +/- 4.84/mm3 &4.67 +/- 1.15/mm3, P = 0.012). Between the two groups, the AUCs of leucocyte and polykaryocyte are 0.926 (95% CI = 0.845-1.0, P = 0.014) and 0.884 (95%CI = 0.786 0.982, P = 0.028), respectively. Their critical values are 44/mm3 (sensitivity = 1, specificity = 0.907) and 3/mm3 (sensitivity = 1, specificity = 0.837). Conversely, CSF protein and glucose have no statistic differences between the two groups. CONCLUSION: Both CSF leukocyte and polykaryocyte can satisfactorily indicate whether the post-neurosurgical bacterial meningitis has completely been cured, 0-44/mm3 is recommended as the reference range of CSF leukocyte, and the CSF polykaryocyte' s is 0-3/mm3. PMID- 30273843 TI - Low glucagon-like peptide-1 (GLP-1) concentration in serum is indicative of mild cognitive impairment in type 2 diabetes patients. AB - OBJECTIVES: To reveal potential association between glucagon-like peptide 1 (GLP 1) concentration in serum and mild cognitive function impairment (MCI) in type 2 diabetes mellitus (T2DM) patients. PATIENTS AND METHODS: A total of 106 T2DM patients and 47 normal controls were recruited in this study. Montreal Cognitive Assessment (MoCA) was performed in all subjects. Among the 106 patients, 52 presented with MCI. Fasting blood glucose (FBG), total cholesterol (TC), low density cholesterol (LDL-C), high-density cholesterol (HDL-C), triglyceride (TG), uric acid (UA) and GLP-1 levels were also assessed in all subjects. RESULTS: Patients with MCI had higher serum concentrations of FBG and TC and lower concentrations of GLP-1 and HDL-C than controls. Bivariate correlation analysis showed that MCI in T2DM patients closely correlated with FBG, HDL-C, and GLP-1 levels. Moreover, ordinal regression analysis showed that GLP-1 concentration in serum was protective for MCI in T2DM patients (OR = 0.025; 95%CI: 0.005-3.934). CONCLUSIONS: Our results indicated that low concentration of GLP-1 may play a role in the pathogenesis of MCI in T2DM patients. PMID- 30273844 TI - LCD: A Fast Contrastive Divergence Based Algorithm for Restricted Boltzmann Machine. AB - Restricted Boltzmann Machine (RBM) is the building block of Deep Belief Nets and other deep learning tools. Fast learning and prediction are both essential for practical usage of RBM-based machine learning techniques. This paper proposes Lean Contrastive Divergence (LCD), a modified Contrastive Divergence (CD) algorithm, to accelerate RBM learning and prediction without changing the results. LCD avoids most of the required computations with two optimization techniques. The first is called bounds-based filtering, which, through triangle inequality, replaces expensive calculations of many vector dot products with fast bounds calculations. The second is delta product, which effectively detects and avoids many repeated calculations in the core operation of RBM, Gibbs Sampling. The optimizations are applicable to both the standard contrastive divergence learning algorithm and its variations. In addition, this paper presents how to implement these optimizations effectively on massively parallel processors. Results show that the optimizations can produce several-fold (up to 3X for training and 5.3X for prediction) speedups. PMID- 30273845 TI - Development of a system dynamics model for polycyclic aromatic hydrocarbons and its application to assess the benefits of pollution reduction. AB - A dynamic multimedia transport (DMT) model for polycyclic aromatic hydrocarbons (PAHs) was constructed using the system dynamics software STELLA to simulate the transmission and flow of PAHs in different media. Humans are primarily exposed to PAHs via ingestion. Thus, this study used the DMT model to simulate the concentrations of PAHs in food media and the human body and assess the risk of harm to humans. On the basis of the hypothesis of PAH reduction in the Taiwanese steel industry, two scenarios were used (cases I and II), and integration indicators such as the Air Resource Co-Benefit Model of air pollutants, greenhouse gases, and PAHs reduction was established for the cost-benefit analysis of the reduction scenarios. This study not only established Taiwan's PAHs dynamic multimedia transmission model successfully but also performed a reduction scenario on the steel industry. In the year 2025, the total costs for cases I and II will be USD 690 and USD 694 million per year, respectively, and the total benefits will be USD 492 and 1669 million per year, respectively. Therefore, case II is preferable to case I in terms of benefit ratio (2.40 vs. 2.35, respectively).

AB - In recent years, increasing efforts have focused on production of organic inorganic compound fertilizers using ammonium sulfite pulping waste liquor. However, their ecological effects on soil have not been studied. In this study, earthworm Eisenia fetida was exposed to various doses (0, 0.13, 0.26 and 0.52 kg/m2) for different time (7, 14, 21, and 28 d) to evaluate the effects of fertilizers made from pulping waste liquor, including reactive oxygen species (ROS) generation, antioxidant enzymes activities, glutathione S-transferase enzyme (GST) activity, malondialdehyde (MDA) content and DNA damage. Results showed that there were significant increase of ROS and MDA levels after 14 d, inducing production of antioxidant enzymes (superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT)) as well as GST. Before 14 d, excess ROS and MDA caused damage to the DNA of earthworms, leading to gradual increase of Olive tail moment (OTM) in the comet assay. With the exposure time extended to 28 d, owing to the combined effects of elimination of free radicals by antioxidant enzymes and detoxification enzymes as well as self-repairing function of cells, ROS and MDA levels declined slightly and OTM gradually decreased. In summary, this study indicated that there was a toxicological effect on earthworms when fertilizers made from pulping waste liquor were applied to soil, which needs more attention. PMID- 30273847 TI - Endocrine disruption, oxidative stress and lipometabolic disturbance of Bufo gargarizans embryos exposed to hexavalent chromium. AB - The aim of the current study was to determine the potential developmental and metabolic abnormalities caused by Cr (VI) exposure on Bufo gargarizans (B. gargarizans) embryos. B. gargarizans embryos were treated with different concentrations of Cr (VI) (13, 52, 104, 208, and 416 MUg Cr6+ L-1) for 6 days. Morphological abnormalities, total length, weight and developmental stage were monitored. Malformations of embryos were also examined using scanning electron microscopy (SEM). In addition, the transcript levels of several genes associated with lipid metabolism, oxidative stress, and thyroid hormones signaling pathways were also determined. Our results showed a time-dependent inhibitory effect of Cr (VI) on the growth and development of B. gargarizans embryos. On day 4, total length, weight, and developmental stage were significantly lower at 416 MUg Cr6+ L-1 relative to control embryos. On day 6, significant reductions in total length, weight, and developmental stage were observed at 104, 208, and 416 MUg Cr6+ L-1. Malformed embryos were found in all Cr (VI) treatments, which were characterized by axial flexures, yolk sac edema and rupture, surface tissue hyperplasia, stunted growth, wavy fin and fin flexure. RT-qPCR results showed that exposure to Cr (VI) down-regulated TRbeta and Dio2 mRNA expression and up regulated Dio3 mRNA level at 416 MUg Cr6+ L-1. The transcript levels of SOD and GPx were upregulated at 52, 208, and 416 MUg Cr6+ L-1, while the transcript level of HSP90 was downregulated at 52, 208, and 416 MUg Cr6+ L-1. Also, mRNA expression of lipid synthesis-related genes (FAE and ACC) were significantly downregulated in embryos treated with 208 and 416 MUg Cr6+ L-1, but mRNA expression of fatty acid beta-oxidation-related genes (ACOX, CPT, and SCP) was significantly upregulated at 416 MUg Cr6+ L-1. Therefore, our results suggested that Cr (VI) could disrupt thyroid endocrine pathways and lipid synthesis, leading to the inhibition of growth and development in B. gargarizans embryos. Furthermore, the decreased ability of scavenging ROS induced by Cr (VI) might be responsible for the teratogenic effects of Cr (VI). PMID- 30273848 TI - Quantitative screening level assessment of human risk from PCBs released in glacial meltwater: Silvretta Glacier, Swiss Alps. AB - Persistent organic pollutants (POPs) are entrained within glaciers globally, reemerging in many alpine ecosystems. Despite available data on POP flux from glaciers, a study of human health risk caused by POPs released in glacial meltwater has never been attempted. Glaciers in the European Alps house the largest known quantity of POPs in the Northern Hemisphere, presenting an opportunity for identification of potential risk in an endmember scenario case study. With methodology developed by the US Environmental Protection Agency (EPA), we provide a regional screening level human risk analysis of one class of POPs, polychlorinated-biphenyls (PCB) that have been measured in melt waters from the Silvretta Glacier in the Swiss Alps. Our model suggests the potential for both cancer and non-cancer impacts in residents with lifetime exposure to current levels of PCB in glacial meltwater and average consumption of local fish. For residents with an abbreviated 30-year exposure timeframe, the risk for cancer and non-cancer impacts is low. Populations that consume higher quantities of local fish are predicted to be at a greater risk, with risk to lifetime consumers higher by an order of magnitude. Based on the results of our screening study, we suggest that local government move to the next step within the risk assessment framework: local monitoring and management. Within the Alps, other glacial watersheds of a similar size and latitude may see comparable risk and our model framework can be adapted for further implementation therein. PMID- 30273849 TI - Bacterial community shaped by heavy metals and contributing to health risks in cornfields. AB - Scientists are increasingly aware that heavy metal contamination in soils, especially in farmland ecosystems, can negatively affect human health and alter the bacterial community that plays a critical role in plant growth and heavy metal accumulation. The goal of the present paper was to uncover how various heavy metals and non-metallic elements affect human health and bacterial diversity in cornfields and to explore the contribution of soil bacteria to heavy metal accumulation in crops. Soil samples were collected from five counties in Shandong Province, China, where abnormally high levels of heavy metals and metalloids were caused by mining and heavy industry. We calculated a hazard quotient (HQ) to evaluate the health risk these heavy metals cause and analyzed the soil bacterial community using 16S rRNA gene sequencing. The HQ results showed that As posed the greatest threat to human health followed by Pb although concentrations of all metals did not reach the health risk threshold. Meanwhile, principal component analysis (PCA) and redundancy analysis (RDA) revealed soil bacterial richness was significantly influenced by As, Ni, and Cr as well as pH and phosphorus, but not by the species diversity of aboveground weeds. The most abundant bacteria in our study region were heavy metal tolerant groups, specifically Actinobacteria and Proteobacteria. Moreover, correlation analysis suggested that Actinobacteria might reduce the phytoaccumulation of Cr, Cu, Zn, and Hg in corn, while Proteobacteria might weaken phytoaccumulation of Pb, Ni, As, and Cd. Our results verified that heavy metals play an important role in shaping the soil bacterial community. Using native bacteria in farmland provides a potential biological strategy for reducing the health risk posed by heavy metals related to food consumption. PMID- 30273850 TI - Measurement and prediction of bioconcentration factors of organophosphate flame retardants in common carp (Cyprinus carpio). AB - The increase in the production and usage plus the toxicity nature of organophosphate flame retardants (OPFRs) has become a concern. However, limited information is available about the bioaccumulation potential of OPFRs in fish. In this study, we determined the 96 h LC50 s, and evaluated the bioaccumulation potential of six most frequently reported OPFRs in gill, kidney, liver, and muscle tissues of common carp (Cyprinus carpio) for 48 d, and a quantitative structure-activity relationship (QSAR) model was developed to predict bioconcentration factors (BCFs) for the remaining 16 OPFRs. The BCFs and half lives (t1/2) in the tissues ranged from 6.54 (Tris (2-chloroisopropyl) phosphate, (TCPP)) to 528.15 (Tris (2-ethylhexyl) phosphate (TEHP)), and 2.25-5.78 days, respectively. The tissue-specific concentration and BCFs values followed the order of liver > kidney >= intestine >> muscle. The proposed QSAR model with a high cross-validated value (Q2(cum)) of 0.930 and a correlation coefficient of 0.94 was obtained and was able to predict log BCF from parameters related to molar volume and isotropic average static field polarizability. The results show that the model has a high level of accuracy, making the proposed approach a suitable method for predicting the log BCF.

AB - The focuses of this research is to prepare an efficient magnetic glycopolymer for bacteria removal from aqueous solution. To perform this idea; porous MnFe2O4@SiO2 was functionalized with glucose and or maltose as an anchors to adhere onto bacteria cell surface. Aminopropyltriethoxysilane was employed to link the saccharides on magnetic nanoparticle surface. The hybrid materials were characterized with XRD, VSM, FT-IR, FESEM, TEM, zeta potential measurement and elemental mapping. Microscopic image showed that MnFe2O4 is in cluster form composed from tiny nanoparticles. After saccharide functionalization hybrid composite generate hyper-crosslinked porous structure as a result of polysilicate formation due to hydrolysis of silica source. Escherichia coli and bacillus subtilis were selected as sample pathogens to evaluate the bacteria capturing ability of the magnetic glycopolymer. At the optimum conditions (pH = 6, time of 20 min, dosage of 15 mg) removal efficiency was more than 99% using both saccharide.

AB - This study aimed to determine the efficiencies and mechanisms of hexavalent chromium (Cr(VI)) removal with modified sand coated by Mg-LDHs in constructed rapid infiltration system (CRIS). Mg-LDHs (MgAl-LDHs, MgFe-LDHs) were prepared by co-precipitation method and in situ coated onto the surface of original sand. Scanning Electron Microscope (SEM) and X-Ray Fluorescence Spectrometer (XRFS) were used to analyze physicochemical properties of sand/Mg-LDHs composites. Results obtained confirmed the successful LDHs-coating modification. During the purification experiments, the average removal rates of Cr(VI) were 47.62% for sand/MgAl-LDHs, 34.15% for sand/MgFe-LDHs and 11.61% for original sand, respectively. The sand/Mg-LDHs had a higher Langmuir adsorption capacity and desorption capability for Cr(VI) compared to original sand. The adsorption kinetic data of different adsorbents were better described by pseudo-second-order model. Intra-particle diffusion model was also used to elucidate the adsorption mechanism. Moreover, extracellular polymeric substances, biomass and enzymatic activity of microbes on the modified and original sand were testified and analyzed to study microbial effect on Cr(VI) removal in test columns. Through a rough economic estimation, the reagent cost of sand/MgAl-LDHs synthesis was only RMB Y 0.24/Kg. It could be concluded that MgAl-LDHs modified sand is an efficient and economical substrate of CRIS for Cr(VI) removal. PMID- 30273854 TI - Transcriptomic response of Arabidopsis thaliana roots to naproxen and praziquantel. AB - Exposition to pharmaceutical compounds released to the environment is considered as a potential risk for various organisms. We exposed Arabidopsis thaliana plants to naproxen (NAP) and praziquantel (PZQ) in 5 uM concentration for 2 days and recorded transcriptomic response in their roots with the aim to estimate ecotoxicity and to identify gene candidates potentially involved in metabolism of both compounds. Nonsteroidal anti-inflammatory drug NAP up-regulated 105 and down regulated 29 genes (p-value <= 0.1, fold change >= 2), while anthelmintic PZQ up regulated 389 and down-regulated 353 genes with more rigorous p-value <= 0.001 (fold change >= 2). High number of up-regulated genes coding for heat shock proteins and other genes involved in response to biotic and abiotic stresses as well as down-regulation of genes involved in processes such as cell proliferation, transcription and water transport indicates serious negative effect of PZQ. NAP up-regulated mostly genes involved in various biological processes and signal transduction and down-regulated mainly genes involved in signal transduction and electron transport or energy pathways. Further, two cytochrome P450s (demethylation) and one methyltransferase (methylation of carboxyl group) were identified as candidates for phase I and several glutathione and glycosyltransferases (conjugation) for phase II of NAP metabolism. Cytochrome P450s, glutathione and glycosyltransferases seem to play role also in metabolism of PZQ. Up-regulation of several ABC and MATE transporters by NAP and PZQ indicated their role in transport of both compounds. PMID- 30273853 TI - Current approaches for safer design of engineered nanomaterials. AB - The surge of applications for engineered nanomaterials (ENMs) across multiple industries raises safety concerns regarding human health and environmental impacts. ENMs can be hazardous through various mechanisms, including, particle dissolution and shedding of toxic metal ions, surface reactivity and perturbation of cellular membranes, lysosomal membrane damage, activation of inflammation pathways (e.g., NLRP3 inflammasome), etc. The aim of this review is therefore to discuss practical approaches for the safer design of ENMs through modification of their physicochemical properties that can lead to acute and/or chronic toxicity. This is premised on our understanding of how different ENMs induce toxicity within various biological systems. We will summarize studies that have investigated nanomaterial toxicity both in vitro and in vivo to understand the underlying mechanisms by which nanoparticles can cause inflammation, fibrosis, and cell death. With this knowledge, researchers have identified several design strategies to counter these mechanisms of toxicity. In particular, we will discuss how metal doping, surface coating and covalent functionalization, and adjustment of surface oxidation state and aspect ratio of ENMs could reduce their potential adverse effects. While these strategies might be effective under certain experimental and exposure scenarios, more research is required to fully apply this knowledge in real life applications of nanomaterials. PMID- 30273855 TI - Effect of external resistance on the sensitivity of microbial fuel cell biosensor for detection of different types of pollutants. AB - The relatively poor sensitivity is the main bottleneck restricting the application of microbial fuel cell biosensor (MFC-biosensor) for toxicity monitoring. Previous studies have shown that external resistance (Rext) had an obvious effect on sensor sensitivity. However, these studies reported different results and the reason of this discrepancy was not clear. The objective of this research was to observe the effect of Rext on sensor sensitivity when detecting different types of pollutants and reveal its microbiological mechanism. Results demonstrated that the optimal Rext of MFC-biosensor varied with the type of pollutants. The optimal values for detecting avermectins, tetracyclines and heavy metals were 100 Omega, 330 Omega and 680 Omega, respectively. This discrepancy was mainly due to the visible differences in anodic microbial communities at different Rext settings. Both Azospirillum and Acinetobacter were susceptible to Cd and Pb, occuping 19.20% of the anodic microbial population in 680 Omega MFC biosensor. Pseudomonas accounted for 10.73% in 330 Omega MFC-biosensor and possessed the sensitivity to tetracyclines. As for 100 Omega MFC-biosensor, the avermectin-intolerant Ocillibacter made up 2.55% of the anodic microbial community. This study indicated that the Rext of MFC-biosensor should be optimized according to the potential pollutants. PMID- 30273856 TI - Anxiety attacks with or without life-threatening situations, major depressive disorder, and suicide attempt: a nationwide community sample of Korean adults. AB - Regardless of categorical diagnosis, many psychiatric patients suffer from sudden attack of fear or intense anxiety. In this study, we defined anxiety attacks to refer to these phenomena and investigated their association with depression and suicide attempts. A total of 12,532 adults randomly selected population through the one-person-per-household method completed a face-to-face interview using the Korean version of Composite International Diagnostic Interview (K-CIDI). A total of 5.88% reported to have experienced anxiety attacks. Among them, 46.5% reported to have experienced anxiety attacks without life-threatening situations. 'Anxiety attacks' group reported more suicidal ideation, plan, and attempts, which were even higher frequencies in 'anxiety attacks without life-threatening situations' group than 'anxiety attacks only with life-threatening situations' group and showed stronger association with lifetime suicide attempts when it had comorbid major depressive disorder (MDD) (AOR = 9.69, 95%CI 5.90-15.90), compared with 'never' group. There was no association between each symptom of patients with anxiety attacks and their lifetime suicide attempt. In conclusion, the finding suggests that there are as many individuals who experience anxiety attacks without life-threatening situations as those with life-threatening situations. And anxiety attacks appear to be relevant to an increased risk of suicide attempt, especially without life-threatening situations and with comorbid MDD. PMID- 30273857 TI - Prevalence of depression among type 2 diabetes mellitus patients in India: A meta analysis. AB - Depression as a co-morbid condition in type 2 diabetes mellitus (T2DM) patients is associated with significant morbidity, mortality, and rising health economic burden. Indian healthcare system is heavily burdened with T2DM, and it is important to understand the prevalence of depression associated with T2DM. This meta-analysis conducted as per the registered protocol (PROSPERO registration: CRD42016051552), searched for published studies in the databases including MEDLINE and Embase till 31st August 2018. The modified Newcastle-Ottawa Scale was used to assess the methodological quality. The pooled prevalence of depression among T2DM patients was estimated as primary outcomes, while prevalence based on demographic sub-group was estimated as the secondary outcome. In total, 43 studies including 10,270 patients fulfilled the eligibility criteria and were included in the analysis. The pooled prevalence of depression in T2DM patients was found to be 38% (95% CI: 31%-45%). Presence of depression in people with type 2 diabetes was more often associated with the presence of complications with an odds ratio of 2.33, 95% CI: 1.62-3.36, p < 0.00001. Overall, the study found a high prevalence of depression among T2DM patients in India. Diabetes management programs in India may consider early screening of depression in T2DM patients. PMID- 30273858 TI - Arsenic surface complexation behavior in aqueous systems onto Al substituted Ni, Co, Mn, and Cu based ferrite nano adsorbents. AB - The present study is about surface complexation behavior of arsenic species adsorbed onto ternary metal oxide adsorbents (Ni-Al-Fe, Co-Al-Fe, Mn-Al-Fe, and Cu-Al-Fe). The analysis is carried out by X-ray absorption spectroscopy (XAS) tool. XANES (MU(E) vs. E) spectra close to the absorption edge (i.e., As K-edge) of all samples are observed along with the As(III) and As(V) standards. The first derivative of XANES for Ni-As(V), and Cu-As(V) samples agree with that of As(V) standards, respectively. Whereas, As(III) adsorbed adsorbent systems (i.e., Ni, Co, Mn, and Cu) are observed with mixed oxidation state of arsenic. A total of 65 85 % is observed with initial oxidation state (As(III) or As(V)), and remaining 15-35 % is observed with modified oxidation state (As(V) or As(III)) that explains the occurrence of possible charge transfer. EXAFS analysis shows the As O bond distances in the range of 1.7-1.8 A. The corresponding As-M bond distances are around 2.7, 3.2, and 3.6 A which confirms the formation various edge sharing (2E), and corner sharing (2C, 1V) surface complexes. Surface coverage is understood as an important parameter as bidentate attachments (2E, 2C) are evident in As(III), and As(V), but monodentate attachments (1V) are only observed in As(V). PMID- 30273859 TI - Successful Secondary Engraftment of Pancreatic Ductal Adenocarcinoma and Cholangiocarcinoma Patient-Derived Xenografts After Previous Failed Primary Engraftment. AB - BACKGROUND: Patient-derived xenografts (PDX) provide histologically accurate cancer models that recapitulate patient malignant phenotype and allow for highly correlative oncologic in-vivo downstream translational studies. Primary PDX engraftment failure has significant negative consequences on programmatic efficiency and resource utilization and is due to either no tumor growth or development of lymphoproliferative tumors. We aimed to determine if secondary engraftment of previously cryopreserved patient tumor tissues would allow salvage of PDX models that failed previous primary engraftment and increase overall engraftment efficiency. METHODS: Patient hepatobiliary and pancreatic cancers that failed primary engraftment were identified. Previously cryopreserved primary patient cancerous tissues were implanted into immunodeficient mice (NOD/SCID). Mice were monitored, growth metrics calculated, and secondary engraftment outcomes were recorded. Established PDX were verified and compared to original patient tissue through multiple generations by a GI pathologist. RESULTS: We identified 55 patient tumors that previously failed primary engraftment: no tumor growth (n = 46, 84%) or lymphoproliferative tumor (LT) (n = 9, 16%). After secondary implantation using cryopreserved patient tissues, 29 new histologically validated PDX models were generated with an overall secondary engraftment rate of 53% for all tumor types with greatest yield in pancreatic and biliary tract cancers. Of the secondary engraftment failures (n = 26), 21 (38%) were due to no growth and 5 (9%) developed LT. CONCLUSION: Secondary PDX engraftment using cryopreserved primary cancerous is feasible after previous failed engraftment attempts and can result in a 50% increase in overall engraftment efficiency with decreases in LT formation. This technique allows for salvage of critical patient PDX models that would otherwise not exist. SYNOPSIS: Patient-derived xenografts have many important translational applications however can be limited by engraftment failure. We demonstrate optimized methodology utilizing cryopreservation of primary tumor tissue that allows for subsequent successful secondary engraftment and creation of PDX models that failed previous primary engraftment and allowed salvage of patient PDX models that would otherwise not exist. PMID- 30273861 TI - Uptake and translocation of 14C-Carbamazepine in soil-plant systems. AB - Carbamazepine (CBZ) is an antiepileptic drug that is frequently detected in wastewater treatment plants, soil and plants after irrigation with treated wastewater or application of biosolids. However, little information is available on the fate and uptake of CBZ in edible vegetables. In this study, radioautographic visualization of the 14C distribution revealed that 14C-CBZ can be taken up by all three ready-to-eat vegetables. Furthermore, a mass-balance study was conducted to evaluate the dynamic processes of the uptake and translocation of CBZ by 14C labeling. 14C-CBZ was gradually taken up with the growth of vegetables, with maximum uptake ratios of 2.19 +/- 0.15, 2.86 +/- 0.24 and 0.25 +/- 0.05% of applied 14C in celery, carrot and pak choi, respectively. The bioconcentration factors (BCFs) based on 14C measurements ranged from 7.6 to 26.1 for celery, 3.6-12.9 for carrot, and 4.4-44 for pak choi. 14C-CBZ was easily translocated from the roots to the leaves and/or stems. The amendment of biosolids had a significant inhibitory effect on the uptake and translocation of 14C-CBZ from soil. PMID- 30273860 TI - Markers of Mitochondrial Metabolism in Tumor Hypoxia, Systemic Inflammation, and Adverse Outcome of Rectal Cancer. AB - Tumor hypoxia contributes to therapy resistance and metastatic progression of locally advanced rectal cancer (LARC). We postulated that the tumor mitochondrial metabolism, manifested by reactive oxygen species (ROS) and mitochondrial DNA (mtDNA) damage, reflects how hypoxic conditions connect to cancer-induced systemic inflammation and poor outcome. Levels of ROS and mtDNA damage were analyzed in three colorectal cancer (CRC) cell lines cultured for 24 hours under normoxia (21% O2) or hypoxia (0.2% O2) and serum sampled at the time of diagnosis from 35 LARC patients participating in a prospective therapy study. Compared with normoxia, ROS were significantly repressed and mtDNA damage was significantly enhanced in the hypoxic CRC cell lines; hence, a low ratio of ROS to mtDNA damage was an indicator of hypoxic conditions. In the LARC patients, low serum ROS were associated with elevated levels of circulating carcinoembryonic antigen and tumor choline concentration, both indicative of unfavorable biology, as well as adverse progression-free and overall survival. A low ratio of ROS to mtDNA damage in serum was associated with poor local tumor response to the neoadjuvant treatment and, of note, elevated systemic inflammation factors (C-reactive protein, the interleukin-1 receptor antagonist, and factors involved in tumor necrosis factor signaling), indicating that deficient treatment response locally and detrimental inflammation systemically link to a hypoxic mitochondrial metabolism. In conclusion, serum ROS and damaged mtDNA may be markers of the mitochondrial metabolism driven by the state of oxygenation of the primary tumor and possibly implicated in systemic inflammation and adverse outcome of LARC. PMID- 30273862 TI - Determination of the vertical profile of aerosol chemical species in the microscale urban environment. AB - This study developed a lightweight air composition measuring equipment (ACME) mounted in unmanned aerial vehicles (UAVs) to measure the vertical distribution characteristics of PM2.5 chemical species in the micro-scale urban environment for the first time. 212 samples collected from 0 to 350 m above ground level were analyzed for water-soluble ions. The concentrations of most ions on the above ground level were higher than that on the ground surface during the sampling period. The measurements of the total ion concentrations were approximately 54 to 26% of the PM2.5 mass concentrations on the ground surface. The concentrations of NH4+ and NO3- decreased with increases in the height from the ground, which may be related to the influence of the vehicle emissions and human activities. NO2- and SO42- both had a peak concentration on the higher vertical altitude at night in the sea-land wind system. In the southern wind system, the emissions of sea salts, dust, and stationary pollution, might be transported by the regional prevailing airflow from the southern coastal area, were the major pollutant sources above the boundary layer. The vertical distribution of ionic concentrations and wind field provided information concerning changes in pollutant transport and source regions that affect the local air quality. The ACME mounted in UAVs is the feasible and convenient method to fast understand the vertical distributions of aerosol chemical species. It provides important information about the accumulation and diffusion effects by the boundary layer variation to aerosol characteristics, which is difficulty observed from the conventional ground-based measurements. In future, this technology is the useful application for investigating the pollutant species emitted from the smokestack and the sudden pollution accident. PMID- 30273863 TI - Synergistic effects of phosphorus and humic acid on the transport of anatase titanium dioxide nanoparticles in water-saturated porous media. AB - The (un)intentional release of titanium dioxide nanoparticles (TiO2 NPs) poses potential risks to the environment and human health. Phosphorus (P) and humic acid (HA) usually coexist in the natural environments. This study aims at investigating the transport and retention behaviors of TiO2 NPs in the single and binary systems of P and HA in water-saturated porous media. The experimental results showed that HA alone favored the transport of TiO2 NPs in sand columns to a greater extent than that of P alone at pH 6.0. Interestingly, the co-presence of P and HA acting in a synergistic fashion enhanced the transport of TiO2 NPs in sand-packed columns more significantly compared to that in the single-presence of P or HA. Particularly, P plays a dominant role in the synergistic effect. This is largely due to the competitive effect between P and HA for the same adsorption sites on the sand surfaces favorable for TiO2 NPs retention. A two-site kinetic attachment model that considers Langmuirian blocking of particles at one site provided a good approximation of TiO2 NPs transport. Modeled first-order attachment coefficient (k2) and the maximum solid-phase retention capacity on site 2 (Smax2) for P or HA alone were larger than those in the co-presence of P and HA, suggesting a less retention degree of TiO2 NPs in the binary system of P and HA. Our findings indicate that the mobility of TiO2 NPs is expected to be appreciable in soil and water environments, where P and HA are rich and always co present at low pH conditions. PMID- 30273864 TI - Chemical and biological transfer: Which one is responsible for the maternal transfer toxicity of tris(1,3-dichloro-2-propyl) phosphate in zebrafish? AB - Maternal transfer toxicity of chemicals has mainly focused in fish on the chemical transfer from maternal generation to offspring, and limited information is available for the evaluation of effects of chemicals from a biological transfer perspective. In this study, first-generation (F0) zebrafish larvae (D. rerio) were exposed to 0, 50, 500 or 5000 ng/L TDCIPP from 14 days post fertilization (dpf) to 120 dpf. F0-generation zebrafish were paired, and F1 generation embryos were collected and continuously exposed to the same concentrations of TDCIPP until 150 dpf. F1-generation females were then paired with unexposed adult males, and maternal transfer effects on survival rate and body length were evaluated. Results demonstrated that maternal exposure to TDCIPP for two generations significantly decreased body length of F2-generation larvae, suggesting the occurrence of maternal transfer toxicity. The transfer of TDCIPP from maternal generation to offspring was evident, but microinjection of equal amounts of TDCIPP did not affect survival and body length of zebrafish larvae. Furthermore, maternal exposure to TDCIPP changed the concentrations of partial mRNAs and proteins in their eggs, and those changes were linked to maternal transfer toxicity (e.g., growth inhibition). These results suggested that in zebrafish changes in biological transfer may explain, at least in part, the observed maternal transfer toxicity of TDCIPP. PMID- 30273865 TI - Long-term impact of cement plant emissions on the elemental composition of both soils and pine stands and on the formation of Scots pine seeds. AB - We investigated the long-term impact of the largest Russian cement plant on mesopodzol sandy soils and Scots pine stands. We determined the distributions of the total and available pools of Ca, Mg, K, Na, Mn, Fe, Zn, Ni, Cu, Pb and Cd in the soil profile to a depth of 60 cm (illuvial horizon) as well as the accumulation patterns of these elements in the vegetative and generative organs of Scots pine trees. High Ca accumulation in the impact zone soils was a result of CaO emissions by a cement plant. Also, CaO became the main cause of soil profile alkalization due to neutralization of soil acids and formation of calcium hydroxide or carbonates. Alkalization immobilized substantial amounts of Fe, Mn, Zn and Ni in the soil, reducing their availability. The most prominent effect of long-term cement production was a prominent Mn deficiency in vegetative and generative Scots pine organs due to the exhaustion of the available Mn pool in the illuvial horizon. The miniaturization of cones, a decrease in seed yield and a reduction in seed germinability were observed in the emission impact zones. Pretreatment of Mn-deficient seeds with manganese eliminated Mn deficiency but did not increase seed germination. PMID- 30273866 TI - The interaction between particulate organic matter and copper, zinc in paddy soil. AB - Particulate organic matter (POM) acts as a metals sink in soil, but only a few studies focused on the interaction of POM and heavy metals in paddy soil. The aim of this study is to investigate the interaction between POM and Copper (Cu)/Zinc (Zn). Two levels of Cu (100, 400 mg kg-1) and Zn (250, 500 mg kg-1) were used in a soil culture experiment. Our results showed that POM was porous structure and varied in size. Hydroxyl and carboxyl involved in POM adsorption of Cu and Zn. Rhizosphere effects roughen the surface of POM and enhanced the capacity of POM on heavy metals absorption. Cu-humic (26.2-33.9%) and Cu-citrate (38.5-42.4%) were dominated in POM, and Cu-goethite (41.7-57.7%), Cu-sulphide (6.6-27.6%) was dominated in soil. Rhizosphere effects decreased the proportion of organic-bond Cu along with the increasing the proportion of Cu-sulphide in POM. Addition of Cu and Zn inhibited the degradation of POM but rhizosphere effects promoted. Carbon content was increased in POM by heavy metal and rhizosphere effects. Our findings indicated that POM tended to retain the heavy metals in soil and heavy metals inhibited the degradation of POM, however, rhizosphere effects decreased the stability of POM-metals interactions. PMID- 30273867 TI - Greenspace seems protective of both high and low blood pressure among residents of an Alpine valley. AB - BACKGROUND: There is some data suggesting that residential greenspace may protect against high blood pressure in urbanized areas, but there is no evidence of effects on hypotension, in less urbanized areas, and in idiosyncratic geographic contexts such as mountain valleys. OBJECTIVES: The current study aimed to investigate the associations between residential greenspace and blood pressure in an alpine valley in Austria. METHODS: We conducted a cross-sectional survey of a representative sample of 555 adults living in the Lower Inn Valley, Austria. Several definitions of blood pressure were employed: continuously-measured systolic (SBP) and diastolic blood pressure (DBP), doctor-diagnosed hyper- and hypotension, and high- and low blood pressure medication use. Greenspace metrics considered were: Normalized Difference Vegetation Index (NDVI), Soil Adjusted Vegetation Index (SAVI), and tree cover as measures of surrounding greenness in circular buffers of 100 m, 300 m, 500 m, and 1000 m around the home; distance to different types of structured green space; and having a domestic garden and a balcony. Relationships were examined across different definitions of blood pressure and greenspace and evaluated for potential effect modification by demographic factors, presence of a domestic garden/balcony, adiposity, and traffic sensitivity. RESULTS: Higher overall greenness was associated with 30-40% lower odds of hyper/hypotension and 2-3 mm Hg lower SBP. Similar pattern was revealed for tree cover, however, associations with hypertension were less consistent across buffers, and SBP and DBP were lower only in association with greenness in the 100-m buffer. Having a domestic garden also seemed protective of high DBP. Residing near to forests, agricultural land, or urban green spaces was not related to blood pressure. Higher NDVI500-m was stronger associated with lower SBP in those having a domestic garden, while the effect on DBP was stronger in overweight/obese participants. CONCLUSION: These findings support the idea that greenspace should be considered as protective of both high and low blood pressure, however, underlying mechanisms remain insufficiently understood. PMID- 30273868 TI - The impact of social capital, land use, air pollution and noise on individual morbidity in Dutch neighbourhoods. AB - BACKGROUND: Both social and physical neighbourhood factors may affect residents' health, but few studies have considered the combination of several exposures in relation to individual health status. AIM: To assess a range of different potentially relevant physical and social environmental characteristics in a sample of small neighbourhoods in the Netherlands, to study their mutual correlations and to explore associations with morbidity of residents using routinely collected general practitioners' (GPs') data. METHODS: For 135 neighbourhoods in 43 Dutch municipalities, we could assess area-level social cohesion and collective efficacy using external questionnaire data, urbanisation, amount of greenspace and water areas, land use diversity, air pollution (particulate matter (PM) with a diameter <10 MUm (PM10), PM <2.5 MUm (PM2.5) and nitrogen dioxide (NO2), and noise (from road traffic and from railways). Health data of the year 2013 from GPs were available for 4450 residents living in these 135 neighbourhoods, that were representative for the entire country. Morbidity of 10 relevant physical or mental health groupings was considered. Individual-level socio-economic information was obtained from Statistics Netherlands. Associations between neighbourhood exposures and individual morbidity were quantified using multilevel mixed effects logistic regression analyses, adjusted for sex, age (continuous), household income and socio-economic status (individual level) and municipality and neighbourhood (group level). RESULTS: Most physical exposures were strongly correlated with degree of urbanisation. Social cohesion and collective efficacy tended to be higher in less urbanised municipalities. Degree of urbanisation was associated with higher morbidity of all disease groupings. A higher social cohesion at the municipal level coincided with a lower prevalence of depression, migraine/severe headache and Medically Unexplained Physical Symptoms (MUPS). An increase in both natural and agricultural greenspace in the neighbourhood was weakly associated with less morbidity for all conditions. A high land use diversity was consistently associated with lower morbidities, in particular among non-occupationally active individuals. CONCLUSION: A high diversity in land use of neighbourhoods may be beneficial for physical and mental health of the inhabitants. If confirmed, this may be incorporated into urban planning, in particular regarding the diversity of greenspace. PMID- 30273869 TI - A meta-analysis of blood lead levels in India and the attributable burden of disease. AB - Multiple studies in India have found elevated blood lead levels (BLLs) in target populations. However the data have not yet been evaluated to understand population-wide exposure levels. We used arithmetic mean blood lead data published from 2010 to 2018 on Indian populations to calculate the average BLLs for multiple subgroups. We then calculated the attributable disease burden in IQ decrement and Disability Adjusted Life Years (DALYs). Our Pubmed search yielded 1066 articles. Of these, 31 studies representing the BLLs of 5472 people in 9 states met our study criteria. Evaluating these, we found a mean BLL of 6.86 MUg/dL (95% CI: 4.38-9.35) in children and 7.52 MUg/dL (95% CI: 5.28-9.76) in non occupationally exposed adults. We calculated that these exposures resulted in 4.9 million DALYs (95% CI: 3.9-5.6) in the states we evaluated. Population-wide BLLs in India remain elevated despite regulatory action to eliminate leaded petrol, the most significant historical source. The estimated attributable disease burden is larger than previously calculated, particularly with regard to associated intellectual disability outcomes in children. Larger population-wide BLL studies are required to inform future calculations. Policy responses need to be developed to mitigate the worst exposures. PMID- 30273870 TI - Functionalized MoS2-nanosheets for targeted drug delivery and chemo-photothermal therapy. AB - Molybdenum disulfide (MoS2) has been extensively explored for biomedical applications due to its excellent photothermal conversion ability. In this paper, we report a nanoplatform based on folic acid (FA) targeted dual-stimuli responsive MoS2 nanosheets and explore this for the treatment of FA-receptor positive human breast cancer. The nanocomposites generated had a uniform diameter (ca. 133 nm), and could be loaded with the anti-cancer drug doxorubicin (DOX) to a high capacity (151.4 mg/g). The release of DOX was greatly accelerated at pH 5.0 as compared to pH 7.4. In addition, it was found that drug release is enhanced under near infrared laser (NIR) irradiation, showing that the composites can be used as dual responsive systems, with DOX release controllable through pH or NIR irradiation. MTT assays and confocal experiments showed that the MoS2 based nanoplatform could selectively target and kill FA-positive MDA-MB-231 cells (a human breast cancer cell line). The platform also allowed the combination of chemotherapy and photothermal therapy, which led to synergistic effects superior to either monotherapy. The functionalized MoS2 nanoplatform developed in this work hence could be a potent system for targeted drug delivery and synergistic chemo-photothermal cancer therapy. PMID- 30273871 TI - Cytocompatibility assessment of Ti-Nb-Zr-Si thin film metallic glasses with enhanced osteoblast differentiation for biomedical applications. AB - Biologically safe Ti-based quaternary Ti-Nb-Zr-Si thin film metallic glass (TFMG) was fabricated by sputtering on Titanium alloy (Ti6Al4V or Ti alloy) substrates. A preliminary assessment regarding glass forming ability, thermal stability and corrosion behavior was performed. The amorphous nature of the film is evidenced from the X-ray Diffraction (XRD) and Transmission Electron Microscope (TEM) and Selected Area Electron Diffraction (SAED) patterns. Ion scattering spectroscopy (ISS) and X-ray Photoelectron Spectroscopy (XPS) were used to analyse the chemical composition of surface which indicated oxygen on the top surface of the film and confirms the presence of Ti, Nb, Si, Zr without any other impurities. The surface morphology of the film showed a smooth surface as observed from scanning electron microscope (SEM) and atomic force microscope (AFM) analysis. It is found that the TFMG can sustain in the body-fluid, exhibiting superior corrosion resistance and electrochemical stability than the bare titanium. The cytotoxicity studies with L929 fibroblast cells showed that coatings were graded as zero and non-cytotoxic in nature. No hemolysis was observed on the coated surface indicating a better hemocompatibility. Assay using SaOS-2 bone cells showed good growth on the coated surfaces. The calcium assay showed that the SaOS 2 cells grown and differentiated on the control (Tissue Culture Polystyrene) TCPS surface had the highest mineral level. Higher alkaline phosphatase activity is obtained in SaOS-2 osteoblast cell cultures on TFMG than the control. PMID- 30273872 TI - Provitamin supramolecular polymer micelle with pH responsiveness to control release, bioavailability enhancement and potentiation of cytotoxic efficacy. AB - Encapsulation techniques to generate core/shell systems provide a method that improves physicochemical properties, which are very important in biological applications. beta-carotene is a common carotenoid that has shown preventive effects in skin diseases and vitamin A deficiency but this compound has limited water solubility and bioavailability, which hinder its broad application. The use of polyrotaxane compounds formed from cyclodextrins has allowed supramolecular polymer micelles (SMPMs) to be synthesized to encapsulate beta-carotene. The polymeric compound Pluronic F127(r) was also used to create core/shell nanoparticles (NPs) that contain beta-carotene. Bioactive compound encapsulation was fully confirmed by nuclear magnetic resonance spectroscopy and by scanning and transmission electron microscopy. The method based on cyclodextrin and lecithin allow to release slowly when the systems were exposed to an aqueous medium by pH control, with an increase of 16 times of bioavailability comparing with free carotenoid. This allowed to potentiate the cytotoxic activity on a melanoma cell line by enhancing the water solubility to more than 28 mg/L, and present promising applications of SMPMs to provitamins.

AB - Development of nanomaterials has drawn interest on silver nanoparticles (AgNPs), which are being incorporated in several biomedical and environmental applications, especially anti-bacterial properties of AgNPs has intense excitement for their commercial use. However, the impact of AgNPs on cell membranes, such as phospholipid membrane properties, is not clearly understood yet. By applying curcumin as a probe molecule, this work was done for the first time to investigate the effect of AgNPs on membrane properties, such as permeability and phase transition temperature using 1,2-dimyristoyl-sn-glycero-3 phosphocholine (DMPC) liposomes as a model for phospholipid membranes. We concluded that AgNPs at low concentration decrease the partition of curcumin into DMPC liposomes by ~4-fold. In the presence of AgNPs, curcumin was found to be located close to the stern layer of DMPC liposomes by using a hydrophobic quencher, cetylpyridinium bromide (CPB). In addition, AgNPs broadened the phase transition temperature of DMPC liposomes, which ranged from 20 degrees C to 35 degrees C. PMID- 30273874 TI - Optimising treatment of hyperlipidaemia: Quantitative evaluation of UK, USA and European guidelines taking account of both LDL cholesterol levels and cardiovascular disease risk. AB - BACKGROUND AND AIMS: Guidelines for cholesterol-lowering medication either advocate fixed dose statin treatment without low density lipoprotein (LDL) cholesterol targets or treatment aimed at LDL cholesterol goals. The decrease in LDL cholesterol concentration determines the reduction in atherosclerotic cardiovascular disease (CVD) risk. METHODS: As indices of the effectiveness of reductions in LDL cholesterol concentration achieved by the various guidelines, the number of CVD events prevented in 100 people during 10 years of treatment (N100) and the number of people, who must be treated for 10 years to prevent one CVD event (NNT), were calculated taking into account both CVD risk and pretreatment LDL cholesterol concentration. That our method of calculating NNT and N100, could be extended to statin regimens of different intensity or of statin combined with adjunctive cholesterol-lowering medication was demonstrated by meta-analysis. RESULTS: Reductions in LDL-cholesterol concentration are determined by the choice and dose of medication and by the pre-treatment LDL cholesterol concentration. At similar CVD risk, whatever cholesterol-lowering strategy is adopted, people with higher pre-treatment LDL cholesterol benefit more than those with lower levels. Fixed dose statin regimens are less effective than target LDL cholesterol levels of 1.8 or 1.4 mmol/l when pre-treatment LDL cholesterol levels exceed 4 mmol/l. However, fixed dose statin is more effective in people with lower initial LDL cholesterol. The predicted NNT and N100 were closely related to the observed reduction in CVD risk in our meta-analysis. CONCLUSIONS: In hypercholesterolaemia, aiming for LDL cholesterol targets with statin dose titration (and when necessary adjunctive medication) is essential to optimise benefit.

AB - Plastic pollution in natural water bodies is an emerging problem that requires quick actions. Recently, the role of micro- and nanoplastics in pollution and health issues has been realized and taken seriously. In this paper, we have studied optical properties, such as NIR spectra and refractive index, of some common plastic materials and present a method and data to screen especially problematic transparent plastics with rough surface in aquatic environments. We also give an outlook of possible optical measurement methods that could be used for detection of micro- and nanoplastics. PMID- 30273876 TI - Chronic fluoride exposure induces neuronal apoptosis and impairs neurogenesis and synaptic plasticity: Role of GSK-3beta/beta-catenin pathway. AB - Fluoride is becoming an ineluctable environmental pollutant and its longterm exposure would cause fluorosis and irreversible brain damage, but the molecular mechanisms remain far from fully understood. In the present study, we firstly evaluated the glycogen synthase kinase 3beta (GSK-3beta)/beta-catenin pathway in the hippocampus of rats exposed to fluoride, given the well-established role of GSK-3beta/beta-catenin pathway in neuronal death and survival. Our data showed that sustained exposure to 50 mg/L and 100 mg/L NaF in drinking water dose dependently induced neuronal loss and apoptosis in rat hippocampus. Neurogenesis was also weakened by fluoride administration in the hippocampal dentate gyrus region. Additionally, the synaptic markers, synaptophysin (SYP) and post-synaptic density 95 (PSD95) protein levels, were decreased by 100 mg/L NaF treatment, whereas 50 mg/L NaF only reduced SYP expression, indicating a compromised synaptic function. We further demonstrated that NaF, especially the higher dose, induced GSK-3beta activity, with decreased inactive phosphorylated GSK-3beta levels and increased GSK-3beta, the active form of the kinase. Correspondingly, downstream beta-catenin signaling was undermined by NaF treatment as evidenced by the fact that both two doses of NaF decreased nucleus beta-catenin status and the higher dose of NaF also reduced cytoplasmic beta-catenin protein expression. Taken together, the present study firstly showed the aberrant changes of GSK 3beta/beta-catenin signaling in the fluoride-exposed brain, highlighting the involvement of GSK-3beta/beta-catenin signaling in the fluoride-induced neurotoxicity. PMID- 30273877 TI - Nutrient limitation determines the suitability of a municipal organic waste for phytomanaging metal(loid) enriched mine tailings with a pine-grass co-culture. AB - The suitable phytomanaging of mine tailings not only requires an improvement of soil fertility but also the assessment of the biotic interactions between the selected plant species. This study aimed to evaluate the effect of an organic amendment on the response of two plant species of contrasting habit, a tree, Pinus halepensis and a grass, Piptatherum miliaceum growing on a metal(loid) contaminated substrate collected from mine tailings. Pots containing single plant individuals or their combination, with and without organic amendment (at 10% rate), were established and grown in a greenhouse for 13 months. Plant biomass, foliar ionome, leaf delta15N and metal(loid) concentrations were measured at the end of the experiment. The amendment alleviated P deficiency in the substrate and strongly stimulated biomass production by both plant species (10-fold for pine; 90-fold for the grass), leading to more balanced N/P ratios in leaves (especially for the grass). Co-culture with the grass negatively affected pine growth, decreasing total biomass and leaf delta15N values and inducing severe N deficiency (leaf N/P ratio<10). In contrast, co-culture with pine improved the nutrient status and growth of the grass, but only under non-amended conditions. Needle metal(loid) concentrations in P. halepensis were affected by both amendment addition and co-culture with the grass. High biomass growth with low metal(loid) concentrations in P. miliaceum leaves for the amended treatment makes this grass species suitable for the phytomanagement of metal(loid) polluted tailings, since it achieves high biomass production together with low concentrations of metal(loid)s in edible/senescent parts. PMID- 30273878 TI - A screening test based on hematological and histological biomarkers to evaluate the environmental impacts in tambaqui (Colossoma macropomum) from a protected area in Maranhao, Brazilian Amazon. AB - Nowadays biomonitoring programs can benefit with mathematical models able to correlate biomarkers to monitor water pollution. The aim of this study was to develop a screening test based on hematological parameters and histological lesions in tambaqui (Colossoma macropomum), to allow the assessment of environmental impacts on fish inhabiting a protected area in Maranhao inside of Brazilian Amazon. Samples collected during three years (2012, 2013 and 2014) were grouped by season (dry and rainy) Water samples were also collected for physical chemistry analysis. Blood samples were stained with Acridine Orange to detect micronuclei and erythrocyte abnormalities. Gill tissues were stained with hematoxylin and counterstained with alcoholic eosin, and histopathological lesions were scored on a scale of 1-3, being 1 = minimal pathological importance, 2 = moderate pathological importance and 3 = marked pathological importance. A screening test for evaluating environmental impact was developed by fitting the measured data (necrosis, erythrocyte abnormalities, number of micronuclei) from tambaqui. A three-dimensional surface was fit to the empirical data. Our proposed model predicted the probability of necrosis (observed in euthanized animals) based on the numbers of micronuclei and abnormal erythrocytes (observed in blood samples from live animals) (correlation coefficient R = 0.89). The methodology could be applied for predicting contamination histories (chronic pollution that induces branchial lesions) in rivers using the micronucleus and erythrocyte abnormalities of the fishes (with a simple blood sample). PMID- 30273879 TI - The design of a sunlight-focusing and solar tracking system: A potential application for the degradation of pharmaceuticals in water. AB - Photolysis is considered one of the most important mechanisms for the degradation of pharmaceuticals. Photodecomposition processes to remove pharmaceuticals in water treatment presently use artificial UV light incorporated in advanced oxidation processes. However, UV lighting devices consume a substantial amount of energy and have high operational costs. To develop low energy treatment systems and make good use of abundant sunlight, a natural energy resource as a green technology is needed. As such, a system that combines sunlight focusing, solar tracking and continuous reaction was designed and constructed in the present study, and its application potential as a pharmaceutical water treatment option was tested. Two representative photolabile pharmaceuticals, ciprofloxacin and sulfamethoxazole, were chosen as the target pollutants. The results indicate that the sunlight-focusing system consisting of a UV-enhancing-coated parabolic receiver can concentrate solar energy effectively and hence result in a more than 40% improvement in the direct photolysis efficiency of easily photoconvertible ciprofloxacin. The sunlight-focusing coupled with a solar tracker (SFST) system can improve the sunlight-focusing efficiency by more than 2-fold, thus leading to the maximization of the efficient use of solar energy. Sulfamethoxazole, which is difficult to photoconvert, was successfully degraded by more than 60% compared to direct photolysis through the designed SFST system in the presence of persulfate. The treatment system exhibited good and consistent performance during clear and cloudy days of summer. It is proven that the UV-enhanced coated SFST system with the addition of persulfate indeed has development potential for application in the degradation of pharmaceuticals in water. PMID- 30273880 TI - Graphitic carbon nitride (g-C3N4)-based photocatalysts for water disinfection and microbial control: A review. AB - Microbial contamination in drinking water is of great concern around the world because of high pathogenic risks to humans. Semiconductor photocatalysis has aroused an increasing interest as a promising environmental remediation technology for water disinfection and microbial control. Among various photocatalysts, graphitic carbon nitride (g-C3N4), as a fascinating two dimensional conjugated polymer consisting of low-cost, earth-abundant elements, has drawn broad attention as a robust, metal-free, and visible-light-active material in the fields of both environmental remediation and solar energy conversion. Photocatalytic applications of g-C3N4-based nanomaterials for water splitting, hydrogen production, carbon dioxide reduction, and pollutant degradation have been extensively investigated and systematically reviewed. In contrast, their antimicrobial properties have been explored more recently due to the complex structure and unique metabolism of living microorganisms compared with chemicals. The corresponding rapidly increasing research efforts in the last five years have inspired us to conduct the review. This review is the first to comprehensively summarize the progress in design and antimicrobial performance of g-C3N4-based photocatalysts for water disinfection and microbial control, involving not only bacteria but also viruses and microalgae. Moreover, the underlying inactivation mechanisms of photocatalysts for microorganisms are evaluated to provide further understanding of g-C3N4-based advanced disinfection processes. In addition, some exciting future opportunities and challenges at the forefront of this research platform are pointed out. It is expected that this review can pave a new avenue for the development of a facile, cost-effective, environmental-friendly, and sustainable disinfection alternative. PMID- 30273882 TI - Abnormal cerebellum-DMN regions connectivity in unmedicated bipolar II disorder. AB - OBJECTIVE: Bipolar disorder (BD) is a common psychiatric disease. Previous studies have found abnormalities in structural and functional brain connectivity in BD patients. However, few studies have focused on the functional connectivity (FC) of the cerebellum and its sub-regions in patients with BD. The present study aimed to examine the FC of cerebellum-default mode network (DMN) regions in patients with BD II. METHOD: Ninety patients with unmedicated BD II depression and 100 healthy controls (HCs) underwent resting-state functional magnetic resonance imaging. We selected three pairs of subregions of the cerebellum that are DMN-related (the bilateral Crus I, Crus II, and lobule IX) as seed regions and calculated the whole brain FC for each subregion. RESULTS: Compared with the HCs, the patients with BD II depression showed increased connectivity between the right Crus I and bilateral precuneus and decreased connectivity between the left Crus II and bilateral medial prefrontal cortex (mPFC) and between the left Crus II and right medial frontal gyrus (MFG). There was no significant difference in the whole FC of the left Crus I and bilateral lobule IX between the BD II depression group and the HCs group. LIMITATIONS: This study was cross-sectional and did not examine data from euthymic BD patients. CONCLUSIONS: The findings showed impaired FC of cerebellum-DMN regions in BD; partial FC between the Crus I and precuneus and the Crus II and prefrontal cortex suggests the importance of abnormal cerebellum-DMN regions FC in the pathophysiology of BD. PMID- 30273881 TI - Insomnia predicts increased perceived burdensomeness and decreased desire for emotional support following an in-laboratory social exclusion paradigm. AB - BACKGROUND: Research suggests that insomnia is associated with elevated perceptions of loneliness and social disconnection; however, few quasi experimental studies have tested the relationship between these constructs. This study examined whether insomnia symptom severity predicts changes in perceptions of interpersonal connectedness and desire for emotional support following in laboratory participation in a social exclusion paradigm. METHODS: Young adults (N = 70) completed self-report measures assessing constructs of interest before and after engaging in a social exclusion paradigm (Cyberball). Linear regression analyses were used to evaluate whether baseline insomnia symptom severity predicted perceived burdensomeness, desire for emotional support, and thwarted belongingness after playing Cyberball; analyses controlled for baseline perceived burdensomeness, desire for emotional support, and thwarted belongingness, respectively, as well as baseline social anxiety and depression symptoms. RESULTS: Greater insomnia symptom severity significantly predicted greater feelings of perceived burdensomeness following Cyberball participation, beyond baseline perceived burdensomeness, social anxiety symptoms, and depression symptoms (beta= .24, p = .001). More severe insomnia symptoms also significantly predicted lower desire for emotional support after playing Cyberball, beyond baseline desire for emotional support and social anxiety symptoms (beta= -.14, p = .03) but not beyond baseline depression symptoms (beta= -.16, p = .07). Insomnia symptoms were not significantly associated with thwarted belongingness after Cyberball (beta= -.05-.08, p = .27-.57). LIMITATIONS: Replication in larger samples and using other sleep disturbance indices is needed. CONCLUSIONS: Findings suggest that individuals with more severe insomnia symptoms in the past two weeks experience greater perceptions of being a burden on others and less desire for emotional support in response to social exclusion. PMID- 30273883 TI - Handgrip strength and depression among 34,129 adults aged 50 years and older in six low- and middle-income countries. AB - INTRODUCTION: Handgrip strength is a simple and inexpensive marker of health and mortality risk. It presents an ideal risk-stratifying method for use in low and middle-income countries (LMICs). There are, however, no population-based studies investigating the associations between handgrip strength and depression in LMICs. We aimed to assess these associations among community-dwelling middle-aged and older adults using nationally representative data from six LMICs. METHOD: Cross sectional data on individuals aged >= 50 years from the World Health Organization's Study on Global Ageing and Adult Health were analyzed. Depression was based on the Composite International Diagnostic Interview. Weak handgrip strength was defined as < 30 kg for men and < 20 kg for women using the average value of two handgrip measurements of the dominant hand. Multivariable logistic regression analysis was conducted. RESULTS: The sample included 34,129 individuals (62.4 +/- 16.0 years; 52.1% female). The prevalence of weak handgrip strength and depression were 47.4% and 6.2%, respectively. Individuals with weak handgrip strength had a higher prevalence of depression than those without this condition (8.8% vs. 3.8%; p < 0.001). Across all countries, after adjustment for potential confounders, weak handgrip strength was associated with a 1.45 (95%CI = 1.12-1.88) times higher odds for depression, although some between-country differences were noted. DISCUSSION: Weaker handgrip strength is associated with higher odds for depression in LMICs. Future research should seek to establish the predictive value of this inexpensive measure for clinical use. Furthermore, interventional studies should examine if muscular strength can be a target of resistance-training interventions to address depressive symptoms in low-resourced settings. PMID- 30273884 TI - GxE effects of FKBP5 and traumatic life events on PTSD: A meta-analysis. AB - BACKGROUND: Twin studies have demonstrated that both genetic and environmental factors influence risk for posttraumatic stress disorder (PTSD), and there is some evidence supporting the interplay of genes and environment (GxE). Many GxE studies within the PTSD literature have focused on genes implicated in the stress response system, such as FK506 binding protein 51 (FKBP5). Given inconsistencies across GxE literature as a whole, a meta-analysis to synthesize results is warranted. METHODS: Studies were identified through PubMed and PsycINFO. A meta analysis was conducted using a random effects model in the MAc package in R. Heterogeneity of the effect size distribution was examined with Cochran's Q statistic. A Simes procedure was used to test the gene-level GxE effect for FKBP5 interacting with trauma. RESULTS: A significant gene-level GxE gene effect was demonstrated for FKBP5 when pooled across all four examined variants (rs1360780, rs3800373, rs9296158, rs9470080) when interacting with trauma exposure on PTSD. Significant large GxE effect sizes were also found for each independent variant. There was no evidence for heterogeneity of variance. LIMITATIONS: Limitations include reduced power for detecting variability across moderators, potential bias due to failure of meta-analyzed studies to account for two-way covariate x gene and covariate x environment influences, and a high false discovery rate that is characteristic of GxE analyses. CONCLUSIONS: This is the first study to quantify an overall gene-level effect of FKBP5 in a GxE analysis of PTSD, evidence which may be used to address current issues in the FKBP5 GxE literature (e.g., disparate variants, low sample sizes and power), as well as inform follow-up functional research. PMID- 30273885 TI - How many bereaved people hallucinate about their loved one? A systematic review and meta-analysis of bereavement hallucinations. AB - BACKGROUND: Bereavement hallucinations (BHs) entail a perception of a deceased in any sense modality or as a quasi-sensory sense of presence. BHs are an associated feature of the proposed Persistent Complex Bereavement Disorder (PCBD) in DSM-5. The goals of this review are to estimate the prevalence of BHs, identify possible moderators, and review the methodological status of this research field. METHODS: A systematic literature search was conducted through the databases PubMed, PsycINFO, and CINAHL. Studies systematically assessing the prevalence of BHs of a relative or friend were included. RESULTS: Twenty-one eligible studies were identified and 8 meta-analyses of BHs in different sense modalities were conducted. The prevalence of having one or more BHs was estimated to be 56.6% (95% CI 49.9-63.2), and the estimated prevalence of BHs in specific sense modalities ranged within 7.0-39.7%. Meta-regression analyses revealed associations to age and conjugal bereavement, but results are tentative and dependent on the type of BH in question. LIMITATIONS: The included studies were methodologically heterogeneous. Limitations included the lack of a valid measure of BHs and low sample generalizability. CONCLUSION: This first systematic review and meta-analysis of BHs suggests that more than half of the bereaved people experience some kind of BH. However, there are considerable methodological limitations in the research of BHs, which is of pertinent interest as BHs have been linked to the development of a future diagnosis of clinically impairing grief. A valid measure of BHs needs to be developed and used in high-quality epidemiological research using population-based designs. PMID- 30273886 TI - The association of vision loss and dimensions of depression over 12 years in older adults: Findings from the Three City study. AB - BACKGROUND: The established relationship between vision impairment and depression is limited by the examination of depression only as a unidimensional construct. The present study explores the vision-depression relationship using a dimensional approach. METHODS: 9036 participants aged 65 years and above enrolled in the Three-City study were included. Relationships between baseline near Vision Impairment (VI) or self-reported distance Visual Function (VF) loss with trajectory of four dimensions of depression - depressed affect, positive affect, somatic symptoms and interpersonal problems - over 12 years were examined using mixed-effects models. Depression dimensions were determined using the four-factor structure of the Centre for Epidemiology Studies-Depression Scale (CESD). RESULTS: In the fully adjustment models, mild near VI predicted poorer depressed affect (b = 0.04, p = .002) and positive affect (b = -0.06, p < 0.001) over time, with evidence of longer term adjustment. Distance VF loss was associated with poorer depressed affect (b = 0.27, p <= .001), positive affect (b = -0.15, p = .002), and somatic symptoms (b = 0.18, p <= .001) at baseline, although only the association with depressed affect was significant longitudinally (b = 0.01, p = .001). Neither near VI nor distance VF loss was associated with interpersonal problems. LIMITATIONS: This paper uses a well-supported model of depression dimensions, however, there remains no definite depression dimension model. Distance VF loss was self-reported, which can be influenced by depression symptoms. CONCLUSIONS: Vision impairment in older adults is primarily associated with affective dimensions of depression. A reduction in social connectedness and ability to engage in pleasurable activities may underlie the depression-vision relationship. Older adults with vision impairment may benefit from targeted treatment of affective symptoms, and pleasant event scheduling. PMID- 30273887 TI - Associations between broader autism phenotype (BAP) and maternal attachment are moderated by maternal postpartum depression when infants are one month old: A prospective study of the Japan environment & children's study. AB - BACKGROUND: Broader autism phenotype (BAP) refers to the expression of behavioral and cognitive dispositions similar to autism spectrum disorder. The present study investigated whether mothers' BAP was prospectively associated with maternal attachment, and if postpartum depression modified this association. METHODS: The Japan Environment and Children's Study (JECS) is a national and government-funded birth cohort study that began in January 2011. Among the 103,099 mothers enrolled, 87,369 mothers without a history of depression were included in the analysis. Self-administered questionnaires were used. These included: the Japanese version of the Autism Spectrum Quotient, the Mother to Infant Bonding Scale, and the Edinburgh Postnatal Depression Scale. Logistic regression analyses were performed. RESULTS: The BAP during the second or third trimester of pregnancy was linearly associated with an increased risk of postpartum depression and insecure maternal attachment when infants were one month old (p for trend < 0.001), after adjusting for confounding variables. When stratified by postpartum depression, among the BAP subscales, deficiencies in social skills and communication were associated with an increased risk of insecure maternal attachment in mothers without postpartum depression. The relationships between the BAP subscales and maternal attachment were attenuated among mothers with postpartum depression. LIMITATIONS: Only five items of the Mother to Infant Bonding Scale were used in the present study, and thus the results should be interpreted with caution. CONCLUSIONS: Mothers' BAP was predictive of insecure maternal attachment toward their infant. Postpartum depression partially moderated the associations between mothers' BAP and insecure maternal attachment. PMID- 30273889 TI - Applications of peptide hormone ligands for the treatment of dumping and short bowel syndrome. AB - Dumping syndrome is a common and debilitating complication of upper gastrointestinal surgery. Accelerated gastric emptying and dysregulated secretion of gastrointestinal (GI) hormones are involved in its pathophysiology. Pasireotide, a novel somatostatin analogue, improved dumping in a phase-2 study. Preliminary data suggest that the glucagon-like peptide-1 (GLP-1) analogue liraglutide can also improve dumping. Short bowel syndrome is the most common cause of intestinal failure and involves not only a loss of mucosal absorptive area but also hypersecretion and accelerated transit. GLP-2 is the best studied hormone involved in intestinal adaptation. An increasing body of evidence demonstrates that the GLP-2 analogue teduglutide reduces parenteral support needs. New GLP-2 analogues and analogues of other GI hormones such as liraglutide are being investigated as promising treatments in short bowel syndrome. PMID- 30273890 TI - Developmental trajectories of externalizing behavior from ages 4 to 12: Prenatal cocaine exposure and adolescent correlates. AB - BACKGROUND: Although prenatal cocaine exposure (PCE) has been linked with greater externalizing behavior, no studies have investigated heterogeneity of developmental trajectories in children with PCE to date. The present study aimed to: (1) identify developmental trajectories of externalizing problems in childhood by using a person-oriented analytic approach; (2) examine whether trajectories differ by PCE and other environmental and biological correlates; and (3) investigate how trajectories were associated with adolescent substance use and sexual behavior. METHODS: Adolescents (N = 386; 197 PCE, 187 non-cocaine exposed (NCE)), primarily African-American and of low socioeconomic status, were prospectively enrolled in a longitudinal study at birth. Externalizing problems were assessed with the Child Behavior Checklist (CBCL) at ages 4, 6, 9, 10, 11, and 12. Substance (tobacco, alcohol, marijuana) use, via self-report and biologic assays, and early (before age 15) sexual intercourse were assessed at age 15. RESULTS: Latent class growth modeling indicated four distinctive developmental trajectories of externalizing behavior from ages 4 to 12: low-decreasing group (32%); moderate-decreasing group (32%); accelerated risk group (14%); and elevated-chronic group (22%). PCE and maternal psychological distress interactively differentiated developmental trajectories of externalizing behavior, which were related to subsequent adolescent substance use and early sexual behavior differently across gender. CONCLUSIONS: The two high-risk trajectories (accelerated risk and elevated-chronic groups), comprising 36% of the sample, identified in the present study may reflect multi-causality of early substance use and perhaps greater risk for transition to substance use disorders later in development. PMID- 30273891 TI - Differential relationships between cannabis consumption and sleep health as a function of HIV status. AB - BACKGROUND: There is evidence that regular cannabis use has negative effects on sleep health. Relative to HIV- populations, HIV + individuals consistently report greater sleep impairments. The number of HIV + individuals reporting frequent cannabis use, often to treat sleep issues, has significantly increased recently. It is unknown, however, if HIV status moderates the association between cannabis use and sleep health. The current study, therefore, examines these associations in a sample of HIV + and HIV- adults. METHODS: HIV + and HIV- (N = 107) individuals completed one laboratory visit. Participants completed a 30-day drug use history questionnaire quantifying consumption of cannabis, cigarettes, and alcohol, and a sleep health questionnaire. To verify substance use and HIV status, participants completed a urine toxicology screening and serology testing. RESULTS: HIV + individuals demonstrated lower sleep health than HIV- individuals. Linear regressions indicated that HIV status moderated the association between total 30-day cannabis consumption and sleep health; cannabis consumption was negatively associated with sleep health in HIV-, but not HIV + individuals. This interactive effect was significant after examining cigarette/alcohol use, depression symptoms, and demographic variables as covariates. CONCLUSIONS: These results corroborate studies demonstrating an inverse relationship between sleep health and cannabis consumption. This study also suggests that factors other than cannabis may be associated with lower sleep health in HIV + individuals. Emerging studies suggest that inflammation may mediate effects of cannabis on HIV infection. Future studies examining this mechanism are warranted to understand cannabis further and sleep in HIV + individuals. PMID- 30273893 TI - Elevated C-reactive protein as a predictor of a random one-year clinical course in the first ten years of schizophrenia. AB - We investigate whether C-reactive protein (CRP) levels could predict the clinical course of patients with schizophrenia in a prospective study of 50 stable outpatients during a random 1-year period within the first 10 years of illness. Positive, negative, depressive, and cognitive symptoms were evaluated. Patients with low-grade inflammation (CRP = 3-10 mg/L; 28%) at baseline showed significant worsening of PANSS-positive and general psychopathology at 1-year follow-up compared with those with CRP <= 3 mg/L. Elevated CRP may be a biomarker of poor 1 year clinical course in patients with schizophrenia. PMID- 30273892 TI - History of childhood emotional abuse predicts lower resting-state high-frequency heart rate variability in depressed women. AB - Childhood emotional abuse impairs emotion regulation and increases risk for major depressive disorder in adulthood. Mounting evidence suggests that decreased resting-state high-frequency heart rate variability, an index of parasympathetic function, represents a transdiagnostic biomarker of emotion dysregulation. We propose that adults with histories of major depressive disorder and childhood emotional abuse represent a subpopulation at particularly high risk to exhibit deficits in parasympathetic control. The current report compared resting-state high-frequency heart rate variability across three groups: (1) depressed women who endorsed childhood emotional abuse (N = 11); (2) depressed women without childhood emotional abuse (N = 19), and (3) never-depressed women without childhood emotional abuse (N = 22). Participants completed childhood trauma self reports and assessment of resting-state high-frequency heart rate variability. ANCOVAs comparing the three groups after controlling for health-related, psychiatric, and respiratory factors were significant. Depressed women with childhood emotional abuse exhibited lower high-frequency heart rate variability than both groups without childhood emotional abuse (d's ranging from 0.81-0.92). Surprisingly, psychiatric factors were non-significant predictors, indicating that childhood emotional abuse may have a unique impact on autonomic functioning. Future research on larger samples is needed to disentangle the relative and synergistic burdens of depression and childhood trauma on physiologic indicators of emotion dysregulation. PMID- 30273894 TI - Childhood emotional abuse and neglect in obese patients with and without binge eating disorder: Personality and psychopathology correlates in adulthood. AB - The link between childhood traumatic experiences such as sexual and physical abuse and EDs in adulthood has been widely demonstrated. To date, however, little research focused on the association between emotional abuse and neglect in childhood and Binge Eating Disorder (BED) and obesity in adulthood. We enrolled 127 patients [84 with BED and 43 obese] and 45 healthy controls (HCs). All participants were administered the same battery of psychometric tests. Between group differences were explored and the relationship between emotional abuse and neglect in childhood and personality and psychopathology in adulthood was tested. Obese patients showed higher scores in emotional abuse and neglect and sexual abuse when compared to HCs. Within obese participants, those with BED reported higher emotional abuse and emotional neglect than obese without BED and HCs; the BED group differed in physical and sexual abuse from obese participants. The association between traumatic experiences in childhood and obesity in adulthood has been confirmed independently of the type of trauma. Therapists should take into account the traumatic etiology of BED, in particular psychological abuse, even in those patients who do not recall physical or sexual abuses. Specific techniques to approach traumatic experiences could be applied to BED or non-BED patients. PMID- 30273888 TI - PanCareLIFE: The scientific basis for a European project to improve long-term care regarding fertility, ototoxicity and health-related quality of life after cancer occurring among children and adolescents. AB - AIMS: Survival after cancer diagnosed during childhood or adolescence continues to improve with new treatments and supportive therapies. Optimal long-term care requires that risks to vulnerable organs are clearly defined and translated into guidelines that are implemented into practice. PanCareLIFE is a pan-European consortium that addresses survivorship issues comprising fertility, hearing impairment and quality of life. This article describes the scientific basis of PanCareLIFE's studies. METHODS: PanCareLIFE involves 17 partner institutions from eight European countries, with additional 11 data providers from five other countries. Study designs and methods include molecular genetic, cohort and case control studies, a longitudinal study and an intervention study. Ethics and data protection issues have been taken into account from the beginning. RESULTS: PanCareLIFE will investigate the way that treatment impairs female fertility, by evaluating anti-Mullerian hormone levels and the underlying genetic susceptibility to loss of fertility. For our fertility studies, more than 6000 survivors have completed questionnaires, more than 1500 provided serum samples and more than 400 case-control triads have been identified. Fertility preservation guidelines for boys and girls will be developed. More than 2000 survivors have contributed audiograms for the ototoxicity study. Almost 1000 samples were sent for genetic analysis related to ototoxicity and gonadal reserve. The SF-36 questionnaire will measure quality of life in more than 10,000 survivors. CONCLUSIONS: The large number of subjects enrolled in PanCareLIFE and the detailed information accumulated will allow in-depth evaluation of important outcomes. Fertility preservation guidelines will help patients and their families make informed decisions and contribute to their long-term well-being. PMID- 30273895 TI - Associations between TV viewing, sitting time, physical activity and insomnia among 100,839 Brazilian adolescents. AB - Our aim was to examine the relationship between insomnia and levels of physical activity (PA) and time spent sitting and TV viewing among Brazilian adolescents. Data from the Brazilian Scholar Health Survey, a nationally representative survey of 9th grade adolescents [mean: 14.28 years (range: 11-18 years)] conducted in 2015 (n = 100,839) were used. Self-reported insomnia, TV viewing, sitting time and total PA (adapted International PA Questionnaire) were collected. Chronological age, race, type of city (capital or interior) country region, goodies ingestion and ultra-processed foods ingestion were covariates. Logistic regression analyses were conducted to assess the associations. A higher sitting time and TV viewing (>=8 h/day) was associated with a higher risk of insomnia among boys [sitting time: OR = 2.39 (95%CI = 1.88-3.04); TV:OR = 2.49(95%CI = 1.92-3.22) and girls [sitting time: OR = 2.17(95%CI = 1.84-2.57; TV:OR = 1.72(95%CI = 1.44-2.04)]. More than 4 h of sitting time per day was associated with higher risk of insomnia in adolescents who comply [boys: OR = 1.43(95%CI = 1.19-1.73); girls: OR = 1.66(95%CI = 1.41-1.94)] and who do not comply with the 300 min/week of physical activity recommendation [boys = OR = 1.35(95%CI = 1.13 1.60); girls: OR = 1.38(95%CI = 1.20-1.57)]. Our data suggest that higher levels of TV viewing or sitting are associated with sleep difficulties in this large cohort of adolescents, irrespective of their physical activity behavior. PMID- 30273896 TI - Comparing cognitive clusters across first- and multiple-episode of psychosis. AB - Cognitive impairments in psychotic disorders (PD) present heterogeneously across patients. Between 2 and 5 clusters have been identified in previous studies with first-episode (FEP) and multiple-episodes of psychosis (MEP) patients suggesting different profiles of impairment. Past findings suggest there are differences between FEP and MEP patients regarding severity and number of affected cognitive domains. Heterogeneity of cognitive deficits in PD has perhaps hindered our understanding of their course. The present study compared non-affective FEP and MEP patients to assess whether illness chronicity could influence cognitive impairment profiles. We analyzed cognitive data, collected with the Cogstate Schizophrenia Battery, of FEP and MEP patients using cluster analysis. We compared clustering methods to obtain a more robust solution. For FEP patients, data were collected at their entry to a specialized clinic; the MEP group consisted of in- and outpatients. Results suggested cognitive heterogeneity was similar in FEP and MEP samples, although in different proportions. Three clusters were identified as the most stable solution and comprised groups of patients with either 1- no cognitive impairment (over-representation of FEP), 2- generalized deficits (over-representation of MEP), or 3- intermediate impairments. These findings encourage early interventions adapted to the profile of impairment. PMID- 30273897 TI - Biomarkers of adverse childhood experiences: A scoping review. AB - Adverse Childhood Experiences (ACEs) are stressful and/or traumatic experiences that occur during childhood. Research has demonstrated a link between ACEs and risk of physical and mental health disorders, where early life adversity may become "biologically embedded" and have wide-ranging effects on various physiological systems. The aim of this study was to identify the extent and breadth of recent research activity relating to biological measures of ACEs in adulthood. We undertook a scoping review including published research articles. Medline and PsycINFO were searched for articles from 2007 to July 2017. Articles were eligible if they included adult participants, were written in English, and reported on a biomarker of childhood adversity in adulthood. Forty articles met our inclusion criteria. Studies investigated a range of ACEs that were often measured retrospectively. The studies identified biomarkers related to inflammation (e.g., CRP), cardio/metabolic systems (e.g., BMI), genetics (e.g., telomere length), and endocrine systems (e.g., cortisol), as well as composites of multiple physiological systems. However, not every study identified found significant associations. Health behaviours, emotional distress, social relationships, and socioeconomic factors may help explain some of these associations. Further research is needed to better understand biomarkers of ACEs in adulthood and their relationship to health conditions. PMID- 30273898 TI - Diagnostic differences in verbal learning strategies and verbal memory in patients with mood disorders and psychotic disorders. AB - A better understanding of verbal learning strategies can offer insight to the difference in verbal memory performance and learning between patients with schizophrenia and schizoaffective disorders, non-psychotic major depression, and psychotic major depression. To date, a comparison of the use of verbal learning strategies and verbal memory performance amongst these specific diagnostic groups has not been investigated. This study examined differences in verbal learning and memory between psychotic major depression (n = 31), nonpsychotic major depression (n = 30), and schizophrenia spectrum disorders (n = 17) disorders. Verbal learning and memory were assessed through the use of the California Verbal Learning Test-II (CVLT-II). Correlations and multiple regression analyses were conducted to analyze differences in verbal learning and memory amongst these groups. There were no significant differences in the use of Semantic Clustering. Diagnostic differences were observed in the use of Serial and Subjective Clustering. The psychotic major depression group utilized Serial Clustering strategy significantly less than the nonpsychotic major depression group. Learning strategies significantly predicted learning and recall. These findings lend support to the hypothesis that learning strategies predict verbal memory performance across diagnostic groups. The present study contains useful information on diagnostic differences in verbal learning and memory, and a framework by which treatment could be tailored to enhance learning specific to these diagnostic groups. PMID- 30273899 TI - Anxious and alert? Hypervigilance in social anxiety disorder. AB - The vast majority of research on attentional biases to threat focusses on selective attention, even though several cognitive-behavioral models furthermore assume hypervigilance to be important in this regard. Thus, the current study examined hypervigilance in trait and state social anxiety. We analyzed visual scanpath lengths and fixation counts of participants with Social Anxiety Disorder (SAD) (n = 61) and healthy controls (n = 60) in a combined visual search and eye tracking paradigm, including photographs of facial expressions. Half of all participants were randomly assigned to a state anxiety induction. Interaction effects revealed opposed attentional patterns of participants with SAD as compared to healthy controls considering overall visual scanpath lengths (F(1,117) = 5.32, p = 0.023, eta2partial = 0.043) and fixation counts (F(1,117) = 5.10, p = 0.026, eta2partial = 0.042). Accordingly, participants with SAD showed signs of hypervigilance in the anxiety induction condition. In contrast, there was no main effect of diagnostic group, indicating that individuals with SAD shift their attentional focus to broad scanning behavior only under conditions of threat. Our results add to the small number of existing studies on hypervigilance in SAD and suggest the topic to be promising for future research. PMID- 30273900 TI - Association between neurological soft signs and antioxidant enzyme activity in schizophrenic patients. AB - To determine the relationship between alterations in the activity of the enzymes participating in antioxidative defense system and neurological soft signs (NSS) in schizophrenic patients with the first episode psychosis (SFE, n = 19), patients in relapse (SR, n = 46), and healthy controls (HC, n = 20). NSS intensity and enzymatic plasma activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) were compared between SFE, SR and HC subjects and a follow-up correlation analyses between the enzyme activities and NSS intensity was performed. NSS intensity was increased four times in schizophrenic patients compared with healthy controls. Activities of SOD and CAT were 40% decreased in SFE and these reductions were ameliorated by antipsychotic treatment. GPX activity was 20% decreased in both patient groups compared with controls. A negative correlation between NSS intensity and GPX activity was specifically found in the SFE patients. The data in this report argue that a reduction of GPX activity might be one of the causes for the emergence of NSS at the onset of schizophrenia, and provide the evidence that antipsychotic therapy can attenuate activity reductions of SOD and CAT, but not the activity reduction of GPX and the intensity of NSS. PMID- 30273901 TI - A randomized controlled trial on a smartphone self-help application (Be Good to Yourself) to reduce depressive symptoms. AB - Depressive symptoms are common, yet only a subgroup of individuals receive adequate treatment. To reduce the treatment gap, several online self-help programs have been developed, yielding small to moderate effects. We developed a smartphone self-help application addressing depressive symptoms. We sought to evaluate its feasibility and efficacy in participants reporting a subjective need for help (a diagnosis of depression was not mandatory). We conducted a randomized controlled trial (N = 90). The primary outcome was a reduction of depressive symptoms measured with the Patient Health Questionnaire-9 (PHQ-9). Secondary outcomes included improved self-esteem (Rosenberg Self-Esteem Scale) and quality of life (WHOQOL-BREF). The intervention group obtained access to the application for four weeks, the wait-list group received access after the post assessment. No group differences emerged in either outcome in intention-to-treat analyses. Per protocol analyses with frequent users (i.e., several times a week or more) yielded a small effect size (eta2p = 0.049) at trend level on the reduction of depressive symptoms in favor of the treatment group. However, 39% of the participants did not use the application frequently. Mobile self-help applications represent a promising addition to existing treatments, but it is important to increase patients' motivation to use them. PMID- 30273902 TI - Study on the optical properties of the magnetic circuit corner shape of the magnetic lens. AB - In this paper, we aim to improve the optical properties of magnetic lenses in transmission electron microscope(TEM). First, the mathematical model of the magnetic field is established, and the formula of the reluctance of the magnetic lens at the corner of the magnetic circuit is deduced. The calculation results of the reluctance are obtained by the numerical analysis method. Then, we find that the corner reluctance affects the density distribution of the magnetic flux lines at the corner. Therefore, the structural shape of the corner of the magnetic lens is optimized. The magnetic flux density on optical axis and the corresponding electron optical parameters are obtained by calculations and simulations. The optical properties of the magnetic lens are improved after the optimization. PMID- 30273903 TI - Thirty-day outcomes in patients with acute pulmonary embolism who discontinued anticoagulant therapy before 90 days. AB - BACKGROUND: The contemporary natural history of patients with acute pulmonary embolism (PE) not receiving (or early discontinuing) anticoagulant therapy has not been consistently evaluated. OBJECTIVE: To assess the rate of the composite outcome of PE-related death, sudden death, or recurrent thromboembolism (VTE) within 30 days in all PE patients in whom anticoagulation was not administered or discontinued prematurely (<90 days of anticoagulation). METHODS: We used the RIETE database to assess the incidence rates (per 100 person-days) of the composite outcome within the subsequent 30 days. The risk of these events was compared to PE patients who were anticoagulated for >=90 days. RESULTS: Of 34,447 PE recruited from 2001 to 2017, 47 (0.14%) did not receive anticoagulants and 1348 (3.91%) discontinued it before 90 days. Fatal PE developed in 25 (53%) of those without any anticoagulation and in 45 (3.33%) with premature discontinuations. Sudden death or non-fatal recurrent VTE occurred in 6 (0.45%) and 24 (1.48%) patients, respectively. The incidence of the primary outcome declined logarithmically from 6.36 per 100 patient-days in untreated patients to 0.32-0.13 in those treated for 8-90 days. During the first week of follow-up, the incidence rate was 13.9 and 0.60-0.31 per 100 patient-days, respectively. The adjusted odds of the primary outcome was 27 fold higher in untreated than in treated patients, and progressively decreased to 2.5-7 fold higher in patients treated for at least 7 days. CONCLUSION: The incidence of the composite outcome was highest during the first week, and inversely and logarithmically correlated with the duration of anticoagulant therapy. PMID- 30273904 TI - Accurate 13-C and 15-N molecular crystal chemical shielding tensors from fragment based electronic structure theory. AB - Standard nuclear magnetic resonance (NMR) spectroscopy experiments measure isotropic chemical shifts, but measuring the chemical shielding anisotropy (CSA) tensor can provide additional insights into solid state chemical structures. Interpreting the principal components of these tensors is facilitated by first principles chemical shielding tensor predictions. Here, the ability to predict molecular crystal CSA tensor components for 13C and 15N nuclei with fragment based electronic structure techniques is explored. Similar to what has been found previously for isotropic chemical shifts, the benchmarking demonstrates that fragment-based techniques can accurately reproduce CSA tensor components. The use of hybrid density functionals like PBE0 or B3LYP provide higher accuracy than generalized gradient approximation functionals like PBE. Unlike for planewave density functional techniques, hybrid density functionals can be employed routinely with modest computational cost in fragment approaches. Finally, good consistency between the regression parameters used to map either isotropic shieldings or CSA tensor components is demonstrated, providing further evidence for the quality of the models and highlighting that models trained for isotropic shifts can also be applied to CSA tensor components. PMID- 30273905 TI - Alterations of MEK1/2-ERK1/2, IFNgamma and Smad2/3 associated Signalling pathways during cryopreservation of ASCs affect their differentiation towards VSMC-like cells. AB - Vascular smooth muscle cells (VSMCs) play essential roles in regulating blood vessel form and function and they are required for vascular tissue regeneration. Multipotent adipose derived stromal cells (ASCs) can be differentiated into VSMC like cells, which can be used as a potential VSMC source for the development of vascular tissue. However, the effects of cryopreservation on the differentiation of ASCs towards VSMCs are poorly studied to date. This study compared fresh ASCs (FA) vs. cryopreserved ASCs (CA) with respect to their differentiation potential towards VSMC-like cells. The expression of contractile VSMC markers (such as smoothelin) and cell contractility were investigated. It was found that VSMC-like cells derived from CA expressed smoothelin gene and protein at lower levels and showed compromised contractility in response to vasoconstrictors, when compared with those derived from FA. Moreover, it was demonstrated that this negative effect of cryopreservation could be mediated by MEK1/2-ERK1/2, IFNgamma and Smad2/3 associated Signalling pathways. Treatment of CA with MEK1/2-ERK1/2 activator or IFNgamma neutralizing antibodies enhanced Smad2/3 phosphorylation and showed a rescue of the negative effect of cryopreservation on the differentiation of ASCs towards VSMC-like cells. These findings are important for defining approaches that may use cryopreserved ASCs for vascular tissue regeneration. PMID- 30273906 TI - Locking plate osteosynthesis for a femoral fracture and subsequent nonunion in a patient with osteopetrosis. AB - INTRODUCTION: Osteopetrosis is a skeletal disorder characterized by increased osteodensity and a remodeling defect. The fragility of dense sclerotic bones may lead to an increased incidence of fractures. Although internal fixation can be performed, technical challenges may be experienced because of the increased bone density. Complications such as delayed union, nonunion, or implant failure may occur postoperatively. PRESENTATION OF CASE: We describe a patient with autosomal dominant osteopetrosis type 2 who suffered a shaft fracture below a plate of his right femur. We performed osteosynthesis with a single locking plate. Union was delayed, and plate breakage occurred along with nonunion of the fracture. The nonunion was addressed using double locking plates, which secured fixation and allowed complete fracture healing. DISCUSSION: There were three reasons of nonunion in our case. First, we left gaps between the fragments. Second, we used mainly cerclage wires, rather than screws, for plate fixation, which led to inadequate stability. Third, the patient was large (height 167 cm, weight 93.1 kg), so the single plate provided insufficient fixing force. We then used double locking plates and attained stronger internal fixation with complete fracture healing. CONCLUSION: Double plating with locking plates may be an effective treatment option for femoral fractures in patients with osteopetrosis. PMID- 30273907 TI - A rare case of gradual enlargement of a multifocal myelolipoma of the posterior mediastinum for 12 years after surgical resection of an adrenal myelolipoma. AB - INTRODUCTION: A myelolipoma is a rare benign tumor that is composed of adipose tissue and hematopoietic elements. Myelolipomas most commonly occur in the unilateral adrenal gland. Posterior mediastinal myelolipomas are extremely rare. We herein present a rare case of a multifocal myelolipoma of the mediastinum that gradually enlarged over a 12-year period after surgical resection of an adrenal myelolipoma. This is the first report of multifocal myelolipomas of the posterior mediastinum and adrenal gland. PRESENTATION OF CASE: A posterior mediastinal tumor was incidentally found by chest X-ray and computed tomography (CT) examination of a 74-year-old woman. The patient had a medical history of resection of a myelolipoma of the left adrenal gland 12 years earlier. We performed tumor extirpation under video-assisted thoracic surgery (VATS). The size of the tumor was 4.5 cm, and the postoperative diagnosis was a myelolipoma. DISCUSSION: Posterior mediastinal myelolipomas are extremely rare, and only 39 cases of mediastinal myelolipoma have been reported to date. No reports have described a multifocal myelipoma of mediastinal myelolipoma. To our knowledge, this is the first report of multifocal myelipomas of the adrenal gland and posterior mediastinum. CONCLUSION: A differential diagnosis of myelolipoma of the posterior mediastinum is important in patients with a history of myelolipoma of the adrenal gland. PMID- 30273908 TI - Hepatic myomatous angiomyolipoma diagnosedpreoperatively from specific imaging features: A case report. AB - INTRODUCTION: Hepatic angiomyolipoma is a rare tumour and is difficult to obtain the accurate diagnosis preoperatively because the imaging features are similar to hepatocellular carcinoma. PRESENTATION OF CASE: We present a case study of an 80 year old woman with a liver tumour measuring 6.2 cm * 6.0 cm. We were able to diagnose the tumour preoperatively as a rare hepatic myomatous angiomyolipoma based on the presence of early venous return evident on angiography and small low intensity areas corresponding to fat within the tumour revealed by out-of-phase EOB-MRI. The tumour was removed by minimally invasive surgery and our preoperative diagnosis was confirmed by positive immunoreactivity for both angiomyolipoma-specific human melanoma black 45 and smooth muscle cell positivity for melanin. DISCUSSION: We consider that the information obtained in this case will be useful for preoperative diagnosis of other hepatic angiomyolipomas, thus facilitating more appropriate and less invasive surgery and improving the overall outcome. CONCLUSION: Hepatic myomatous angiomyolipoma is a rare tumour. We illustrated the two specific imaging features to diagnose it preoperatively. PMID- 30273909 TI - Case: Authentic multimodal therapy and liver resection for an initially unresectable intrahepatic cholangiocarcinoma. AB - INTRODUCTION: Although curative resection is an outstanding prognostic factor of intrahepatic cholangiocarcinoma (ICC), certain segments remain unresectable. The standard therapy for initially unresectable ICC is uncertain. In this case report, we reported the feasibility of multimodal chemotherapy and curative resection. CASE: A 59-year-old Asian woman with back pain was referred to the hospital by her family physician regarding liver mass visible on ultrasonography. At admission, the carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) levels were high, and images showed characteristic signs of ICC with intrahepatic metastases and invasions to on the right Glisson's sheath. Multimodal therapy was applied to the ICC, which could not be resected at first. The therapy comprised hepatic arterial chemoembolization with drug-eluting beads (DEB-TACE), angiographic subsegmentectomy (AS), and systemic chemotherapy. Downstaging of the ICC, which results in curative resection, was planned due to non-normalization of the tumor markers, and pathological analysis revealed complete remission. At 34 months after the surgery, the patient was alive without relapse. DISCUSSION: Recently, chemotherapy and/or an interventional approach were reported to be feasible, although unresectable advanced ICC has a poor prognosis. Some studies have reported that multimodal chemotherapy and R0 resection of initially unresectable ICC can prolong survival time. However, some reports have shown high morbidity and mortality associated with initially unresectable ICC treated with multimodal chemotherapy and R0 resection. Our study resulted in complete remission without complications. CONCLUSION: Multimodal chemotherapy and hepatic curative resection on locally advanced ICC are feasible treatment approaches for initially unresectable ICC. PMID- 30273910 TI - Right-to-left ventricular end diastolic diameter ratio in severe sepsis and septic shock. AB - PURPOSE: The ratio of right ventricular end-diastolic diameter (EDD) to left ventricular EDD (RV/LV) is a measure predictive of right ventricular failure. We hypothesized that an increase in RV/LV would be associated with poor prognosis in severe sepsis and septic shock. MATERIALS AND METHODS: This is a retrospective chart review of patients with severe sepsis and septic shock admitted to a medical intensive care unit (ICU) at a single tertiary care hospital. Patients were identified by ICD-9 codes: 995.92 for severe sepsis and 785.52 for septic shock; and had to have an echocardiogram within 48 h of ICU admission. Increased RV/LV was defined as RV/LV >= 0.9. Left and right-sided chamber dimensions were measured according to American Society of Echocardiography guidelines. RESULTS: We included 146 consecutive ICU patients admitted with septic shock (72) or severe sepsis (74). There was no significant difference in ICU mortality in patients with RV/LV >= 0.9 versus RV/LV < 0.9 (p = .49). CONCLUSIONS: An increased RV/LV does not predict mortality in severe sepsis or septic shock. PMID- 30273911 TI - Bioinspired Anti-digestive Hydrogels Selected by a Simulated Gut Microfluidic Chip for Closing Gastrointestinal Fistula. AB - The anti-digestive features given to hydrogels can prolong their action time in gut environment; however, these types of hydrogels have rarely been reported. Inspired by indigestibility of dietary fibers, we introduced an injectable covalent hydrogel through photopolymerization of glycidyl methacrylate-modified xanthan. This newly synthesized hydrogel exhibited a specific concentration dependent porosity, swelling ratio, and stiffness. The intestinal epithelial cells-6 could grow on the surface of the stiffer hydrogel, and achieved their gut barrier functions. A simulated gut microfluidic chip was manufactured to demonstrate the hydrogel's good performance of anti-digestion compared with the current product, fibrin sealant. Furthermore, calcium ions could induce the swelling-shrinking behavior of the hydrogel, which assisted in removing the hydrogels at the proper time so as to avoid the mismatch of hydrogel degradation and tissue regeneration. Therefore, this hydrogel is expected to be an outstanding gut repair material, especially for closing gastrointestinal fistula. PMID- 30273912 TI - KInhibition: A Kinase Inhibitor Selection Portal. AB - Protein kinases constitute a large class of signaling molecules frequently targeted in research and clinical uses. However, kinase inhibitors are notoriously non-specific, making it difficult to select an appropriate inhibitor for a given kinase. Available data from large-scale kinase inhibitor screens are often difficult to query. Here, we present KInhibition (https://kinhibition.fredhutch.org), an online portal that allows users to search publicly available datasets to find selective inhibitors for a chosen kinase or group of kinases. Compounds are sorted by a KInhibition Selectivity Score, calculated based on compounds' activity against the selected kinase(s) versus activity against all other kinases for which that compound has been profiled. The current version allows users to query four datasets, with a framework that can easily accommodate additional datasets. KInhibition represents a powerful platform through which researchers from broad areas of biology, chemistry, and pharmacology can easily interrogate large datasets to help guide their selection of kinase inhibitors. PMID- 30273913 TI - A review on the abuse of three NPS (synthetic cannabinoids, kratom, poppers) among youths in Asia. AB - Abuse of new psychoactive substances (NPSs) among youths is increasing at an unprecedented rate all over the world. In Asia, abuse of synthetic cannabinoids (SCs), kratom, and poppers has been reported, but up to date information related to abuse of these three NPSs is lacking. This literature review focuses on the recent abuse of these three NPS among Asian youth. Many studies have been conducted to investigate the abuse statuses of SCs in Asian youth in Turkey, Japan, and Korea, and many cases of kratom abuse have been reported in Malaysia and Thailand. In addition, concerns have been expressed about the use of kratom in combination with other substances by teenagers. Popper abuse has been reported among many young people in Asia, including Korea and China, and many studies on popper abuse have focused on men who have sex with men in China and Malaysia. Since NPS abuse can have severe adverse effects and create social problems, there is a continuing need to investigate NPS abuse status continuously among young people. PMID- 30273914 TI - Estimation of stature from dimensions of the fourth lumbar vertebra in contemporary middle-aged Finns. AB - BACKGROUND: Accurate stature estimation plays an essential role in the identification of unknown deceased individuals. For cases in which conventional methods of stature estimation are not applicable, we studied the stature estimation potential of the fourth lumbar vertebra (L4) among a large living sample of representative contemporary Finns. We also generated stature estimation equations for the middle-aged Finnish population. MATERIAL AND METHODS: Our study population comprised the Northern Finland Birth Cohort 1966 for which lumbar magnetic resonance imaging (MRI) scans and objective measurements of stature were available from midlife (n=1358). After screening the MRI scans for vertebral pathologies, we measured the maximum and minimum widths, depths and heights of the L4 body with high precision and reliability. We then calculated their sums and means together with approximations of vertebral cross-sectional area and volume. By constructing simple and multiple linear regression models around the L4 parameters, we generated equations for stature prediction, and investigated their accuracy on the basis of the adjusted R squared (R2) and standard error of the estimate (SEE) values of the models. RESULTS: The multiple linear regression models of the mean width, depth and height of L4 yielded the highest prediction accuracies with the lowest prediction errors (for the entire sample, R2=0.621 and SEE=5.635cm; for men, R2=0.306 and SEE=5.125cm; for women, R2=0.367 and SEE=4.640cm). CONCLUSION: When conventional methods for estimating stature are not applicable, the lumbar vertebrae may be utilized for this purpose. Relatively accurate stature estimates can be given on the basis of only L4 dimensions. PMID- 30273915 TI - A new ligand of CD105 screened out by phage display technology provides a reliable identification of recurrent or metastasizing pleomorphic adenoma from pleomorphic adenoma. AB - OBJECTIVES: To assess CD105 expression in pleomorphic adenoma (PA), recurrent pleomorphic adenoma (RPA) and metastasizing pleomorphic adenoma (MPA), to identify new epitopes and screen a ligand with high affinity to CD105 by phage display technology, to evaluate the reliability of the new ligand for identifying RPA/MPA from PA. METHODS: Phage display technology was used to screen ligands with high affinity to recombinant human CD105. The ligand with strongest affinity to CD105 was synthesized by FMOC Chemistry according to the sequencing results. The archived formalin fixed paraffin-embedded (FFPE) tissues of 35 PA cases, 12 RPA cases and 2 MPA cases were sliced and immunofluorescent stained. CD105 expression were detected by Confocal laser scanning microscopy (CLSM). The relative fluorescence intensity was calculated with the image processing software Image J. Statistical analyses were performed by the software Graph Pad Prism (Version 7.0a). Using PROC logistic, receiver operating characteristic (ROC) curves, area under ROC curves (AUCs) were generated to assess the sensitivity and specificity of the new ligand for identifying RPA/MPA from PA cases. RESULTS: A ligand with specialty and high affinity to CD105 i.e. ligand nABPK296 were developed. FITC-labeled ligand nABPK296 confirmed the difference of CD105 expression in RPA/MPA and PA. The AUC of nABPK296 was 0.9418. CONCLUSIONS: CD105 is a promising biomarker for identification of RPA/MPA from PA cases. Ligand nABPK296 provides a promising approach to CD105 detection. This study also validated the reliability of phage display technology in finding new episodes and ligands with high affinity for antigens. PMID- 30273916 TI - Changes in the function and phenotype of resident peritoneal macrophages after housing in an enriched environment. AB - Exposure to an enriched environment (EE) affects not only brain functions but also immune responses upon viral or bacterial infections. In this study, we examined changes in the phagocytic response and chemokine production of resident peritoneal macrophages after mice had been housed under EE conditions for 6 or 8 weeks, and then explored the possibility that EE could cause a change in the macrophage phenotype by means of flow cytometry as well as quantitative RT-PCR. The percentages of EE macrophages phagocytosing S. aureus and apoptotic neutrophils were significantly larger than those of standard environment (SE) macrophages. After coculturing with S. aureus, EE macrophages tended to produce greater amounts of chemokines such as MIP-2, KC and MCP-1 than SE ones, although the increases for MIP-2 and KC were not statistically significant. As compared with SE macrophages, EE macrophages included more CD40-positive cells (M1 marker), and expressed more mRNAs of IL-6 (M1 marker) and IRF4 (M2 marker), and less mRNA of CD38 (M1 marker), suggesting either the possibility that EE macrophages are a mixed population of M1 and M2 macrophages or the possibility that they are a unique population with a mixed M1 and M2 macrophage phenotype. PMID- 30273917 TI - Leonurine inhibits IL-1beta induced inflammation in murine chondrocytes and ameliorates murine osteoarthritis. AB - Osteoarthritis (OA) is a chronic degenerative joint disease characterized by cartilage degradation, subchondral bone sclerosis and synovitis. Leonurine, an active component extracted from the leaves of Herba leonuri, has been reported to possess various potent biological effects such as anti-oxidant, anti-apoptosis, and anti-inflammatory. However, the therapeutic benefits of leonurine on OA have not been reported. This study aimed to evaluate the therapeutic effect of leonurine on chondrocytes and in murine OA models. Murine chondrocytes were pre treated with leonurine (5, 10, and 20 MUM) for 2 h and then stimulated with IL 1beta for 24 h. Production of NO, PGE2, IL-6, TNF-alpha, MMP-3, MMP-13, and ADAMTS-5 was assessed with the Griess reagent and ELISAs. The mRNA expression of COX-2, iNOS, MMP-3, MMP-13, ADAMTS-5, aggrecan, and collagen-II was tested with real-time polymerase chain reaction. The protein expression of iNOS, COX-2 and NF kappaB-related signaling molecules was measured with western blotting. In this study, leonurine visibly inhibited the IL-1beta-induced production of NO, PGE2, IL-6 and TNF-alpha; and decreased the expression of iNOS, COX-2, MMP-3, MMP-13 and ADAMTS-5 in chondrocytes. Furthermore, leonurine significantly suppressed IL 1beta-stimulated NF-kappaB activation. In addition, treatment with leonurine not only prevented cartilage destruction and subchondral bone thickening, but also alleviated synovitis in a murine OA model. Taken together, these results suggest that leonurine may be a potential therapeutic agent in OA treatment. PMID- 30273918 TI - Centralization and directional preference: An updated systematic review with synthesis of previous evidence. AB - BACKGROUND: Centralization and directional preference are common management and prognostic factors in spinal symptoms. OBJECTIVE: To update the previous systematic review. DESIGN: Systematic review to synthesis multiple aspects of centralization and directional preference. METHOD: Contemporary search was made of multiple databases using relevant search terms. Abstracts and titles were filtered by two authors; relevant articles were independently reviewed by two authors for content, data extraction, and quality. RESULTS: Forty-three additional relevant articles were found. The quality of the studies, using PEDro for randomized controlled trials, was moderate or high in six out of ten RCTs; moderate or high in six out of 12 cohort studies. Prevalence of centralization was 40%, the same as the previous review. Directional preference without Centralization was 26%; thus Centralization and directional preference combined was 66%, which was very similar to the previous review. Neither clinical response was recorded in about a third of patients. Centralization and directional preference were confirmed as key positive prognostic factors, certainly in patients with low back pain, but limited evidence for patients with neck pain. There was no evidence that these might be important treatment effect modifiers. One study evaluated reliability, and found generally poor levels, despite training. CONCLUSIONS: Centralization and directional preference are worthwhile indicators of prognosis, and should be routinely examined for even in patients with chronic low back pain. But they do not occur in all patients with spinal problems, and there was no evidence that they were treatment effect modifiers. PMID- 30273919 TI - Muscle fiber conduction velocity of the vastus medilais and lateralis muscle after eccentric exercise induced-muscle damage. AB - Change in muscle fiber conduction velocity (MFCV) has been reported after eccentric exercise induces muscle fiber damage, most likely due to a change in membrane permeability of the injured fiber. The extent of damage to the muscle fiber depends on the morphological and architectural characteristics of the muscle fibers. Morphological and architectural characteristics of the VMO muscle fibers are different from VL muscle. Thus, it is expected that eccentric exercise of quadriceps muscle results in a non-uniform fiber damage within the VMO and VL muscle and, as a consequence, non-uniform changes in membrane excitability and conduction velocity. The aim of the study was to investigate MFCV of the VMO and VL muscles before and 24 h after eccentric exercise. Multichannel surface EMG signals were concurrently recorded from the right VMO and VL muscles of 15 healthy men during sustained isometric contractions at 50% of the maximal force. Maximal voluntary force significantly reduced after eccentric exercise with respect to the pre-exercise condition (P < 0.0001). MFCV decreased over time during the sustained contractions at faster rates when assessed 24 h after exercise (VMO = -26.1; VL = -20.1) with respect to the pre-exercise condition (VMO = -9.1; VL = -13.7, P < 0.0001). Moreover, VMO showed a greater rate of reduction in MFCV over sustained contraction (26.1 +/- 10.7%) in comparison with VL muscle (20.1 +/- 8.5%, P < 0.025) 24 h after eccentric exercise. The result indicates that eccentric exercise contributes to a larger reduction in MFCV within the VMO muscle as compared to the VL muscle. This may abolish the ability of VMO to counteract the lateral pull of the VL muscle during knee extension, thereby leaving the knee complex more vulnerable to injury. PMID- 30273920 TI - Application of MR-derived cross-sectional guideline of cervical spine muscles to validate neck surface electromyography placement. AB - The importance of surface-EMG placement for development and interpretation of EMG assisted biomechanical models is well established. Since MR has become a reliable noninvasive cervical spine musculoskeletal diagnostic tool, this investigation attempted to illustrate the anatomical relationships of individual cervical spine muscles with their paired surface-EMG electrodes. The secondary purpose of this investigation was to provide an MR cross-sectional pictorial and descriptive guideline of the cervical spine musculature. MR scans were performed on a healthy adult male subject from skull to manubrium of the sternum. Prior to scanning, MR safe markers were placed over neck muscles following surface EMG placement recommendations. Twenty-three neck muscles were traced manually in each of 267 scan slices. 3-D models of the neck musculoskeletal structure were constructed to aid with understanding the complex anatomy of the region as well as to identify correct EMG electrode locations and to identify muscles' curved lines-of-action. 3D models of the MR-safe markers were constructed relative to the target muscles. Based on the findings of this study, muscle palpation and bony landmarks can be used to effectively identify appropriate surface EMG electrode locations to record upper trapezius, middle trapezius, semispinalis capitis, splenius capitis, levator scapulae, scalenus, sternocleidomastoid and hyoid muscles activities.

PMID- 30273923 TI - Left cerebral hemisphere hydrophilic polymer embolism associated with endovascular WEB treatment of a ruptured aneurysm of the anterior cerebral artery. AB - Hydrophilic polymer embolism (HPE) is a rare, likely under-recognized iatrogenic complication, caused by fragmentation of surface materials used on endovascular medical devices. The organs most often involved in HPE are the brain and lungs, resulting in both local and systemic reactions. We present the case of a cerebral HPE associated with WEB treatment of a ruptured aneurysm of the anterior cerebral artery, and involving diffusely the left cerebral hemisphere. The patient developed pneumonia and status epilepticus, and died 24 days after the endovascular procedure, most likely as a result of the sequelae of the aneurysm rupture. The precise role of HPE in the sequence of events leading to death can remain, as in this case, a matter for speculation. However, the potential role of HPE in the events leading to death following diagnostic and therapeutic procedures should be appropriately assessed, especially when recovery does not progress as expected. PMID- 30273922 TI - Quadriceps-strengthening exercise and quadriceps and knee biomechanics during walking in knee osteoarthritis: A two-centre randomized controlled trial. AB - OBJECTIVE: To assess the effect of quadriceps strengthening on quadriceps muscle force, power, and work and tibio-femoral compressive loads during walking in adults with knee osteoarthritis. METHODS: Study design: Two-center, randomized, controlled trial. INTERVENTION: Patients with knee osteoarthritis were randomly allocated to quadriceps strengthening program (3 times weekly) or no attention control group. MAIN OUTCOME MEASURES: Primary outcome was change from baseline in peak quadriceps force during walking at 12 weeks. Secondary outcomes included quadriceps power and work, knee compression forces during walking estimated with musculoskeletal modeling, muscle strength and pain and function. Outcomes were measured at baseline and 12 weeks. RESULTS: 30 patients were randomized to receive either training (n = 15) or no attention (n = 15). At follow-up, there were no statistical differences between groups for maximum quadriceps force, quadriceps positive power, negative work, and positive work, and knee compressive force. Maximum negative quadriceps power in early stance was statistically significantly increased 36% in the training group compared to the control group which was most likely partially a response to faster walking velocity at follow up. Muscle strength and patient reported pain and function were improved in the training group compared to the control group. CONCLUSIONS: Quadriceps strength training leads to increased muscle strength and improved symptomatic and functional outcomes but does not change quadriceps or knee joint biomechanics during walking. The biomechanical mechanism of improved health with strength training in knee osteoarthritis patients remains unknown. ClinicalTrials.gov Identifier: NCT01538407.

PMID- 30273924 TI - Recency of migration, region of origin and women's experience of maternity care in England: Evidence from a large cross-sectional survey. AB - BACKGROUND: In the UK, changes to legislation in 2003 regarding the free movement of people in the European Union resulted in an increase in immigration from countries that joined the EU since 2004, the Accession countries. OBJECTIVE: To describe and compare the maternity experiences of recent migrant mothers to those who had been resident in the UK for longer, and to UK-born women, while taking into account their region of origin. DESIGN: Cross-sectional national survey. SETTING: England, 2009. PARTICIPANTS: Random sample of postpartum women. MEASUREMENTS: Questionnaires asked about demographic characteristics, care during pregnancy, labour, birth and postnatally, about country of origin and, if not born in the UK, when they came to the UK. Country of origin was grouped into UK, Accession countries, and rest of the world. Recency of migration was grouped into recent arrivals (0-3 years), and earlier arrivals (4 or more years since arrival). Descriptive statistics and binary logistic regression were used to explore women's experiences of care. Stratified analyses were used to account for the strong correlation between recency of migration and region of origin. FINDINGS: Overall, 5332 women responded to the survey (a usable response rate of 54%). Seventy-nine percent of women were UK-born. Of the 21% born outside the UK, a third were born in Accession countries. All migrants reported a poorer experience of care than UK-born women. In particular, recent migrants from the Accession countries were significantly less likely to feel that they were spoken to so they could understand and treated with kindness and respect. CONCLUSIONS: Given the rising population of non-UK-born women of childbearing age resident in the UK and the relatively high proportion from Accession countries, it is important that staff are able to communicate effectively, through interpreters if necessary. IMPLICATIONS FOR PRACTICE: The differences in clinical practice between women's home countries and the UK should be discussed so that women's expectations of care are informed about the options available to them. PMID- 30273926 TI - Convergent regulation of PIFs and the E3 ligase COP1/SPA1 mediates thermosensory hypocotyl elongation by plant phytochromes. AB - The ability of plants to sense and integrate daily and seasonal changes in light and temperature and to adjust their growth and development accordingly, is critical to withstand severe weather oscillations in a year. While molecular mechanisms controlling light responses are relatively well established, those involved in the perception and response to temperature are just beginning to be understood. Phytochromes emerged as major temperature sensors; due to warmer temperatures accelerate the dark reversal reaction to the Pr inactive state. Downstream of phytochromes, the bHLH Phytochrome Interacting Factors, and in particular PIF4, act as central signaling hubs to growth coordination in response to light and temperature cues, and to the gibberellin and brassinosteroid pathways. Here we discuss recent findings showing that phytochromes control PIFs activity not only by signaling their destruction in the light, but by modulating transcriptional repression of these factors by the circadian clock. Together with this repression, phytochromes inactivate the COP1/SPA ubiquitin ligase, which negatively regulates light signaling through degradation of a large set of nuclear photomorphogenesis-promoting factors that suppress PIFs activity. PMID- 30273927 TI - Oxygen Regulation in Development: Lessons from Embryogenesis towards Tissue Engineering. AB - Oxygen is a vital source of energy necessary to sustain and complete embryonic development. Not only is oxygen the driving force for many cellular functions and metabolism, but it is also involved in regulating stem cell fate, morphogenesis, and organogenesis. Low oxygen levels are the naturally preferred microenvironment for most processes during early development and mainly drive proliferation. Later on, more oxygen and also nutrients are needed for organogenesis and morphogenesis. Therefore, it is critical to maintain oxygen levels within a narrow range as required during development. Modulating oxygen tensions is performed via oxygen homeostasis mainly through the function of hypoxia-inducible factors. Through the function of these factors, oxygen levels are sensed and regulated in different tissues, starting from their embryonic state to adult development. To be able to mimic this process in a tissue engineering setting, it is important to understand the role and levels of oxygen in each developmental stage, from embryonic stem cell differentiation to organogenesis and morphogenesis. Taking lessons from native tissue microenvironments, researchers have explored approaches to control oxygen tensions such as hemoglobin-based, perfluorocarbon-based, and oxygen-generating biomaterials, within synthetic tissue engineering scaffolds and organoids, with the aim of overcoming insufficient or nonuniform oxygen levels and nutrient supply. PMID- 30273928 TI - KU70 Inhibition Impairs Both Non-Homologous End Joining and Homologous Recombination DNA Damage Repair Through SHP-1 Induced Dephosphorylation of SIRT1 in Adult T-Cell Leukemia-Lymphoma Cells. AB - BACKGROUND/AIMS: Adult T-cell leukemia-lymphoma (ATL) is an aggressive disease which is highly resistant to chemotherapy. Studies show that enhanced ability of DNA damage repair (DDR) in cancer cells plays a key role in chemotherapy resistance. Here, we suggest that defect in DDR related genes might be a promising target to destroy the genome stability of tumor cells. METHODS: Since KU70 is highly expressed in Jurkat cells, one of the most representative cell lines of ATL, we knocked down KU70 by shRNA and analyzed the impact of KU70 deficiency in Jurkat cells as well as in NOD-SCID animal models by western blot, immunofluorescence, flow cytometry and measuring DNA repair efficiency. RESULTS: It is observed that silencing of KU70 resulted in accumulated DNA damage and impaired DDR in Jurkat cells, resulting in more apoptosis, decreased cell proliferation and cell cycle arrest. DNA damage leads to DNA double-strand breaks (DSBs), which are processed by either non-homologous end joining(NHEJ) or homologous recombination(HR). In our study, both NHEJ and HR are impaired because of KU70 defect, accompanied with increased protein level of SHP-1, a dephosphorylation enzyme. In turn, SHP-1 led to dephosphorylation of SIRT1, which further impaired HR repair efficiency. Moreover, KU70 deficiency prolonged survival of Jurkat-xenografted mice. CONCLUSION: These findings suggest that targeting KU70 is a promising target for ATL and might overcome the existing difficulties in chemotherapy. PMID- 30273929 TI - Unbalanced 14;X Translocation and Pattern of X Inactivation in a Female Patient with Multiple Congenital Anomalies. AB - We report on a female patient who was first evaluated at the age of 6 years with developmental delay, dysmorphic facial features, seizures, and autistic behavior. A brain CT showed complete agenesis of the corpus callosum, and EEG recorded bilateral epileptogenic foci. Karyotype analysis revealed 45,X,psu dic(14;X)(p11;p22). FISH using 14q and Xp subtelomeric probes, combined with a SHOX gene-specific probe, and centromere X and XIST gene analysis revealed ish psu dic(14;X)(D14S1420+; DXYS129-, SHOX-, DXZ1+, XIST+). Array CGH detected a 2 Mb loss at Xp22.33 and a 4.6-Mb gain at Xp22.2p22.12. The deletion contains 34 genes, of which CSF2RA and SHOX are OMIM morbid genes. The duplication also contains some OMIM morbid genes, of which CDKL5, NH5, RPS6KA3, and AP1S2 are the most important. The late replicating chromatin technique was used to detect the pattern of X inactivation in the normal X and in the translocated chromosome. The translocated X was found to be inactive in 70% of the studied blood lymphocytes with patchy extension of inactivation to chromosome 14. In conclusion, the phenotype of the patient may be partially affected by the haploinsufficiency of the genes that are known to escape X inactivation and that lie within the deleted region and by other deleted or duplicated genes on the abnormal X chromosome due to an alternative pattern of X inactivation. The phenotype of the patient was significantly aggravated and complicated by the functional monosomy of some genes on chromosome 14 due to partial spreading of inactivation and silencing of those genes. This case report indicates the importance of structural and functional studies and emphasizes the clinical importance of the follow-up of abnormal microarrays.

PMID- 30273931 TI - Inflammation in Diabetic Kidney Disease. AB - BACKGROUND: Diabetes is a growing public health problem. Diabetic kidney disease (DKD) is the most prevalent chronic renal disease and the major cause of end stage renal failure worldwide, predominantly due to the increase of Type 2 diabetes associated with obesity. The intimate mechanisms leading to the development and progression of renal injury in DKD are not well understood, but current knowledge indicates that its pathogenesis is multifactorial, where the immune response and inflammation appear to be relevant factors. SUMMARY: This review summarizes the role of relevant inflammatory molecules and pathways that participate in the development of DKD. Likewise, we focused on the new therapeutic approaches based on anti-inflammatory effects of different drugs. Key Messages: This new pathogenic perspective of DKD as an inflammatory condition leads to novel horizons, such as the potential role of inflammatory signaling pathways and their downstream products as emerging biomarkers and promising therapeutic targets. PMID- 30273932 TI - Relationship of Autophagy and Apoptosis with Total Occlusion of Coronary Arteries. AB - BACKGROUND The primary aim of this study was to evaluate the level of autophagy and apoptosis enzymes in patients with coronary artery disease (CAD). Furthermore, we investigated the role of autophagy and apoptosis in the progression of coronary collateral and coronary total occlusion (TO). MATERIAL AND METHODS We enrolled 115 patients in this prospective, observational, controlled study, who were categorized into 3 groups as follows: group 1, patients with chronic TO (n=49); group 2, patients with acute TO such as myocardial infarction (n=36); and group 3, healthy control patients (n=30). We used the enzyme-linked immunosorbent assay (ELISA) kit for autophagy-related protein 5 (ATG5) and apoptosis (M30) in the plasma for these 3 groups. RESULTS Autophagy levels significantly varied among the groups (13.7+/-5.3 ng/mL, 11.7+/ 3.4 ng/mL, and 7.5+/-3, respectively; P<0.001). In addition, apoptosis levels significantly varied among the groups (78.6+/-33.4 ng/mL, 64.9+/-30.6 ng/mL, and 47.6+/-18.2, respectively; P<0.001). The subgroup analysis revealed significant positive correlations between the autophagy level and the Rentrop score in contrast to apoptosis in group 1 (r=0.463; P<0.001). CONCLUSIONS This study determined that autophagy and apoptosis levels were higher in patients with CAD than in healthy controls. In contrast to the serum apoptosis level, serum autophagy levels demonstrated a significant positive correlation with the Rentrop score. Hence, an elevated autophagy level might be a potential activator and marker of the process by which the body protects itself in CAD. PMID- 30273934 TI - Noninvasive Liver Fibrosis Tests in Patients with Nonalcoholic Fatty Liver Disease: An External Validation Cohort. AB - The main aim of this study was the comparative evaluation of nonalcoholic fatty liver disease (NAFLD) fibrosis score (NFS), fibrosis 4 index (FIB-4), AST-to Platelet Ratio Index (APRI), and enhanced liver fibrosis (ELF) test in distinguishing none/early (F0/F1) from significant/advanced (F2/F3) fibrosis in NAFLD patients, thereby providing an external validation cohort. Thirty-one patients with biopsy-proven NAFLD and 10 matched controls without NAFLD were prospectively enrolled. Serum hyaluronic acid (HA), aminoterminal propeptide of type III procollagen (PIIINP), tissue inhibitor of metallo-proteinases (TIMP)-1, and biochemical tests were measured. NFS, FIB-4, APRI, and ELF were calculated. ELF, FIB-4, and APRI, but not NFS, were higher in F2/F3 than F0/F1 group. Specifically, ELF [area under the ROC curve (AUROC): 0.86+/-0.10; p=0.004) and APRI (AUROC: 0.86+/-0.07; p=0.005], but not NFS (AUROC: 0.68+/-0.12; p=0.16), and FIB-4 (AUROC: 0.71+/-0.11; p=0.10), could similarly discriminate F0/F1 from F2/F3 stage. The sensitivity, specificity, positive predicted value (PPV), and negative predicted value (NPV) were: a) for cut-off of APRI=0.5, 85.7%, 70.8%, 46.2%, and 94.4%, respectively, and b) for cut-off of ELF=9.0, 85.7%, 83.3%, 60.0%, and 95.2%, respectively. When ln(PIIINP) or TIMP-1 were combined with APRI, the combined AUROCs could distinguish F2/F3 from F0/F1, but without significantly higher accuracy compared with APRI alone. APRI could also distinguish patients with simple steatosis from nonalcoholic steatohepatitis, and those with from those without lobular inflammation and ballooning, findings warranting further research. In conclusions: The application of ELF test and APRI can distinguish F0/F1 from F2/F3 fibrosis stages in NAFLD patients. PMID- 30273935 TI - The 3PAs: An Update on the Association of Pheochromocytomas, Paragangliomas, and Pituitary Tumors. AB - Pituitary adenomas (PA) and pheochromocytomas/paragangliomas (PHEO/PGL) are rare tumors. Although they may co-exist by coincidence, there is mounting evidence that genes predisposing in PHEO/PGL development, may play a role in pituitary tumorigenesis. In 2012, we described a GH-secreting PA caused by an SDHD mutation in a patient with familial PGLs and found loss of heterozygosity at the SDHD locus in the pituitary tumor, along with increased hypoxia-inducible factor 1alpha (HIF-1alpha) levels. Additional patients with PAs and SDHx defects have since been reported. Overall, prevalence of SDHx mutations in PA is very rare (0.3-1.8% in unselected cases) but we and others have identified several cases of PAs with PHEOs/PGLs, like our original report, a condition which we termed the 3 P association (3PAs). Interestingly, when 3PAs is found in the sporadic setting, no SDHx defects were identified, whereas in familial PGLs, SDHx mutations were identified in 62.5-75% of the reported cases. Hence, pituitary surveillance is recommended among patients with SDHx defects. It is possible that the SDHx germline mutation-negative 3PAs cases may be due to another gene, epigenetic changes, mutations in modifier genes, mosaicism, somatic mutations, pituitary hyperplasia due to ectopic hypothalamic hormone secretion or a coincidence. PA in 3PAs are mainly macroadenomas, more aggressive, more resistant to somatostatin analogues, and often require surgery. Using the Sdhb +/- mouse model, we showed that hyperplasia may be the first abnormality in tumorigenesis as initial response to pseudohypoxia. We also propose surveillance and follow-up approach of patients presenting with this association. PMID- 30273933 TI - The heart in systemic lupus erythematosus - A comprehensive approach by cardiovascular magnetic resonance tomography. AB - BACKGROUND: In systemic lupus erythematosus (SLE), cardiac manifestations, e.g. coronary artery disease (CAD) and myocarditis are leading causes of morbidity and mortality. The prevalence of subclinical heart disease in SLE is unknown. We studied whether a comprehensive cardiovascular magnetic resonance (CMR) protocol may be useful for early diagnosis of heart disease in SLE patients without known CAD. METHODS: In this prospective, observational, cross-sectional study CMR including cine, late gadolinium enhancement (LGE) and stress perfusion sequences, ECG, and blood sampling were performed in 30 consecutive SLE patients without known CAD. All patients fulfilled at least 4/11 American College of Rheumatology (ACR) Criteria for the classification of SLE. RESULTS: 30 patients (83% female) were enrolled, mean age was 45+/-14 years and mean SLE disease duration was 10+/ 8 years. 80% had low to moderate disease activity. All had a low SLE damage index. CMR was abnormal in 13/30 (43%), showing LGE in 9/13, stress perfusion deficits in 5/13 and pericardial effusion (PE) in 7/13. Patients with non ischemic LGE had more often microalbuminuria while patients with stress perfusion deficits a history of hypertension, renal disorder as ACR criterion, repolarisation abnormalities on ECG and larger LV enddiastolic volume index. There was no correlation between clinical symptoms and CMR results. CONCLUSION: Our study shows that cardiac involvement as observed by CMR is frequent in SLE and not necessarily associated with typical symptoms. CMR may thus help to detect subclinical cardiac involvement, which could lead to earlier treatment. Additionally we identify possible risk factors associated with cardiac involvement.

AB - The aim of the study was to analyze associations between utilization of gynaecological cancer screening (GCS) and the number of months during which state unemployment benefits (Social Security Code II) were drawn by women aged 20 to 35 years. The sample included 223 women with complete interview data (participation rate: 69%). The findings show that more women drawing unemployment benefits for a short-term (<12 months) utilized GCS compared to those receiving long-term benefits (>36 months). PMID- 30273936 TI - [Influence of Parental Body Measurements on Birth Weight of Eutrophic Term Newborns with Special Consideration of Paternal Body Measurements]. AB - A significant influence of maternal body height and weight on neonatal birth outcome has been confirmed before, whereas the influence of paternal traits is rather unknown. In order to analyze the correlation between parental body measurements and the birth weight of newborns, data of 1312 eutrophic term newborns and their parents were collected based on a multicenter study in 10 participating German maternity clinics. The collected data included the birth weight of the infants and the body height and weight of their parents. The results show a significant correlation between infant birth weight and maternal body height. Even with a constant body height and body weight of fathers in a range between 176-184 cm and 76-84 kg, taller mothers gave birth to children with a higher birth weight than shorter mothers. Furthermore, higher maternal body weight is also correlated with increased birth weights, although this correlation is attenuated in higher maternal weight groups. Data regarding body weight and body height of fathers showed similar results with regard to birth weight of the newborns. At a constant maternal body height (164-172 cm) and weight (56-64 kg), the body weight of newborns significantly correlates with the body height of fathers but not with their body weight. The multivariable regression analysis resulted in the following ranking of influence factors on the birth weight of newborns: 1) body height of mother, 2) body weight of mother, 3) body height of father. The results gave support to the assumption of a certain genetic influence of parental body stature on their neonates but argue for an even stronger impact of maternal environmental conditions on the developmental status of neonates. PMID- 30273938 TI - [Obstacles in Secondary Analysis of Routine Data From Primary Care]. AB - BACKGROUND: Routinely recorded data from everyday ambulatory medical care are urgently needed for health services and systems research, but this faces major limitations in Germany. In 2018, European General Data Protection Regulation (GDPR) and new German Federal Data Protection Act (FDPA) become effective. Via simulated real-life scenarios it may be possible to find out if access to and utilization of routine data for research becomes easier or faces additional obstacles. METHODS: General practitioners, information scientists, data trustees and privacy protection experts create concepts, processes and standards for lawful handling of routinely recorded data for secondary research and study their feasibility in 2 scenarios (anonymous and pseudonymous data utilization). From the point of view of technical assessment and privacy protection, technical and organizational obstacles are presented as well as the legal framework. RESULTS: Outdated software interface, insufficient maintenance by software vendors, burdens associated with organization and cost as well as poor IT standards place obstacles to systematic and longitudinal use of healthcare routine data. Future pan-European law for privacy protection will allow research utilization of ambulatory data in principle. However, there are persisting conflicts between individual (fundamental right of privacy protection) and public interests (research for quality and efficiency of public spending; European market's free exchange of goods and services). This becomes evident especially when using routine data via pseudonymization. DISCUSSION: Neither insurmountable hurdles by privacy protecting law nor a threat from Big Data are currently the major obstacles to secondary utilization of routine data but real-life problems at the technology and operational level. GDPR and FDPA that have become into effect in May 2018 have improved European legal unity and transparency of patients' interests. Tension between privacy protection of data on an identified or identifiable person and scientific utilization and exchange of such data in public interest necessitates additional legal clarification. One possible solution, an advanced and ready-to-use software interface, awaits implementation. PMID- 30273939 TI - [Future of Regional Health Care in Germany: Where Do Young Dentists Want to Work?] AB - STUDY AIM: In the context of a shortfall in medical care, the question arises whether a similar trend in dental care may be anticipated. This study analyses preferred working regions and future town-country distribution of young dentists in Germany. METHODS: This online-survey was conducted in spring 2017. It is the second wave of the longitudinal nationwide study "Y-dent: Professional identity of future and young dentists". Study end points were (1) favoured permanent working region of young dentists, (2) favoured future working city size, and (3) correlation between the region of origin and the favoured working region. RESULTS: 625 (51.2% of contacted) young dentists participated in this study. Dental chambers and associations of health insurance dentists in southern and western Germany were the most favoured future working regions. Regions in eastern Germany as well as smaller regions were chosen less often (<10%). For approximately half of the participants, medium-sized cities were an option, and some young dentists were ready to work in smaller cities. Depending on the federal state, 57-95% of young dentists entertained the idea of working in their region of origin. CONCLUSION: Based on young dentists' statements on their favoured future working region, it can be concluded that there is no risk of a shortfall in dental care comparable to the shortfall in medical care. A proportion of young dentists is willing to work in thinly populated or rural areas. PMID- 30273940 TI - Community-based Mental Healthcare: A Case Study in a Cross-border Region of Germany and the Netherlands. AB - BACKGROUND: Community-based mental healthcare (CBMH) aims at supplying psychiatric patients with rehabilitative care outside the hospital. The aim of this study was to compare the organization of CBMH in a cross-border region of Germany and the Netherlands. METHOD: Semi-structured interviews gave insight into characteristics of CBMH approaches applied in the German region of Aachen (IHP) and the Dutch Province of Limburg (FACT). We applied a Delphi technique to select a performance indicator (PI) set for CBMH, which served as a conceptual model to allow comparison. RESULTS: Both approaches are flexible, patient-centred and include the evaluation of quality. Both provide financial and administrative support for the access. CONCLUSION: CBMH approaches appear to be equally valid from several perspectives even if they revealed, at the same time, important differences related to scope, integration with non-CBMH care resources and geographic coverage. Secondarily, the study provides a contribution to the development of a PI set to compare and evaluate CBMH approaches. PMID- 30273941 TI - [Preventive Home Visits for Elderly People: A Systematic Appraisal of Current Application in Germany]. AB - OBJECTIVE: Preventive home visits (PHV) are a measure for promoting the health of elderly people. A study of these measures used over the past 40 years in many countries across the globe revealed a very diverse picture regarding targeted groups, applied structures and intervention contents. So far, there has been no clear evidence of their effectiveness on outcomes such as mortality, need for care, hospital or nursing home admissions. However, a steady increase in PHV programmes in Germany warrants an examination of the current national practice. MATERIAL/METHODS: PHV programmes in Germany were identified in the course of Internet-based research (January 2018) and systematically compared by means of nine criteria that were defined beforehand. RESULTS: 38 PHV programmes were included: 26 currently implemented, and 12 that have been terminated. These showed a considerable variety in terms of their programme components. Medicine oriented and social environment-oriented programmes (n=8 vs. n=24) could be differentiated. Relevant differentiation criteria were sponsorship, profession of home visitors and intervention contents. Thus, the practice in Germany is characterised as follows: municipal sponsorship, social workers conducting home visits, and guidance by consulting services disregarding integrated case management. Programmes of this type mainly emerged only in the current decade. CONCLUSIONS: PHV for elderly people evolved from initially medicine-oriented into rather social environment-oriented programmes of municipal public service. They target elderly people with unclear need for support who, at the same time, are confronted with barriers to accessing suitable services. The anticipated main effect of PHV relates to the safeguarding of social participation. However, evidence for their effectiveness, still pending, should be made available before a broad or even legally anchored application is envisaged. PMID- 30273942 TI - [National Action Plan Health Literacy: Need, Objective and Content]. AB - In recent years, studies on health literacy of the population have been conducted in many countries. Most of them show that health literacy levels are worse than expected and that large parts of the population have low health literacy levels. National strategies and action plans to promote health literacy have been developed in many countries to address these results. Following these examples, a National Action Plan on Health Literacy was also developed for Germany. A panel of 15 experts was involved in the 2-year development process. Based on an analysis of available literature on health literacy and existing action plans, the concept, objectives and priorities of the action plan were defined, and recommendations were developed. The National Action Plan on Health Literacy formulates recommendations in the fields of living environments, the healthcare system, chronic illness, and research.

AB - BACKGROUND: Burn trauma in paediatric patients continues to be highly relevant socio-economically since the number of inpatients treated per year has not declined over the past few decades. The treatment of paediatric burn victims places high demands on medical staff and the use of wound dressings and surgical techniques. This study aimed to give a current overview of the inpatient management and treatment methods for paediatric burn patients at a specialised burn centre in Vienna. PATIENTS/MATERIAL AND METHODS: All children and adolescents who were treated at the children's ward of the Division of Plastic and Reconstructive Surgery at the Medical University of Vienna between 2012 and 2016 due to a recent burn trauma were retrospectively analysed. RESULTS: 115patients were treated due to a recent burn trauma. Median age was 2 years (0 18). Scalds accounted for 74 % of traumas. Median affected body surface area was 5 % (1-40 %). Conservative treatment of superficial partial-thickness wounds (62 %) was performed with MepilexAg in 98 % of cases and required a median healing time of 11 days (4-34). 38 % (n = 44) of patients had deep partial-thickness or full-thickness burns . The use of Suprathel after tangential excision of the burn eschar in more superficial deep partial-thickness burns led to satisfying healing times. CONCLUSION: The use of modern dressings in the conservative treatment of superficial partial-thickness burns allows for atraumatic dressing changes and fast recoveries. The use of Suprathel in more superficial deep partial-thickness burns is a reliable and safe alternative to autologous skin grafting. Scar prophylaxis and regular follow-up examinations are crucial to prevent secondary morbidity due to scar contractures. It is important to raise awareness among parents in order to decrease the number of paediatric burn patients in the future.

AB - BACKGROUND: In industry as well as in the private sector, cement is often used as building material. Although severe skin injuries are known to be caused due to improper handling of cement, the incidence and severity of these cutaneous injuries are often underestimated. Heavy cement burns are rare but in our centers the authors treat affected patients on a regular basis. The aim of this study is to analyze the given patient data in order to give treatment suggestions. PATIENTS AND METHODS: During 2013 to 2017, a total of 7 patients (median age: 39 years), which had suffered chemical burns after concrete, cement or screed exposure, were treated in two German plastic-surgical clinics. The authors performed a retrospective data analysis by using the hospital information systems (HIS). RESULTS: All patients were treated with surgical interventions. Median inpatient treatment period was 9.8 days (n = 6). The average time for surgery was 1:04 hours (n = 5). During surgical treatment an average of 1.4 operations were performed (n = 7). In all cases a sustained wound healing could be achieved. CONCLUSIONS: If a patient suffers from a concrete burn, a fast and competent initial treatment is imperative in order to prevent worse. The presented patient cases prove the value of these rare but devastating medical conditions. Therefore, it is essential to implement the given treatment recommendations for a sustainable patient care. PMID- 30273946 TI - Antidiabetic Potentials of Citrus aurantifolia Leaf Essential Oil. AB - Citrus aurantifolia leaf essential oil was extracted via hydrodistillation, chemical composition of the oil was analyzed using gas chromatography-mass spectrometry and its antidiabetic potentials was assessed in alloxan-induced hyperglycaemic rats using metformin as the reference drug for comparison. Chemical analysis showed that D-limonene (57.84%) was the major constituent of the oil. Other notable compounds identified were neral (7.81%), linalool (4.75%), sulcatone (3.48%) and isogeraniol (3.48%). Intraperitoneal administration of C. aurantifolia oil (100 mg/Kg b.wt.) to hyperglycaemic rats for 14 days caused significant reduction in fasting blood and hepatic glucose, whereas hepatic concentration of glycogen was significantly increased. Also, improvement in dyslipidaemia was observed in C. aurantifolia essential oil-treated hyperglycaemic rats; serum concentration of total cholesterol, triacylglycerol and low density lipoprotein-cholesterol were significantly reduced and high density lipoprotein-cholesterol was increased, resulting in decreased predisposition of rats to cardiac risks. Antihyperglycaemic potential of administration of the oil was lower but compared favourably with the oral antihyperglycaemic agent used as reference antidiabetic drug. Overall, data from this study showed that essential oil from the leaf of C. aurantifolia grown in North-Central Nigeria is a D-limonene chemotype. The oil showed considerable glucose lowering effect as well as the potential to ameliorate hyperglycaemia induced dyslipidaemic complications in alloxanized rats.

AB - PURPOSE: To identify factors influencing the long-term survival at home in stroke patients after neurological inpatient rehabilitation. METHODS: The study was conducted as a prospective cohort study in 204 stroke patients who were treated in the course of one year in the Herzogenaurach Rehabilitation Hospital (rehabilitation phases C and B). The social data and clinical data were collected during inpatient rehabilitation. The outcome variable was assessed up to 5 years after discharge. Differences between groups were analysed with t-tests or chi square tests. Binary logistic regression analyses were carried out for multivariate predictor analyses. RESULTS: The regression analysis resulted in a prediction model consisting of 5 variables for living at home 2.5 years after discharge (vs. institutionalization or death): a greater increase in health related quality of life during inpatient rehabilitation, better health-relate quality of life at discharge, a greater increase in functional independence during inpatient rehabilitation, a higher body-mass index and fewer comorbidity conditions associated with a mortality risk. 5 years after discharge the prediction model consists of 3 variables: lower age, fewer comorbidity conditions associated with a mortality risk and lower risk for falls at discharge from neurological rehabilitation. CONCLUSION: Up to 2.5 years after discharge the extent of functional improvement and the improvement of health related quality of life, which are both correlated with therapeutic effects, are predictors for survival and living at home. On the other hand, 5 years after discharge biological factors as age and comorbidities are prognostically dominating.

AB - AIM: Evaluation of German-language guidelines for aphasia and dysarthria rehabilitation, and comparison with international guidelines. METHODS: The quality of the 6 included guidelines, as found through a comprehensive literature search, was sytematically evaluated using AGREE II. Quality ratings were compared to the results of a systematic review of 19 English-language guidelines. RESULTS: The quality of German-language guidelines was heterogeneous. In 2 out of 6 evaluation domains and in the overall assessment, no German-language guideline reached the cut-off of 66,67% for good guideline quality. Apart from the domain Editorial Independence, results remained behind those of the international reference guidelines. CONCLUSION: In some cases, quality can be improved by simple means. It is more resource-intensive, but crucial to document search strategies and how evidence was used in guideline development. A harmonization of the German-language guidelines seems desirable.

AB - This study explored the usability of 15 different assistive input devices for persons with severe motor disabilities. Fifteen people without disabilities were asked to speak a predefined test-sentence and then to write it using 15 different input aids. Ten persons with severe motor and communication disabilities wrote the same sentence using their own communication aid. The usability was evaluated in 3 dimensions: efficiency (speed as information transfer rate in bit per second), effectiveness (proportion of correct input over all input including errors and error correction), and user's satisfaction with an adapted version of the Quest II questionnaire. Participants without disabilities needed 40 to 140 times more time to write the sentence using the aid compared to speech, participants with disability between 13 to 500 times. The effectiveness was between 80 and 100% for the participants without disabilities and between 73 and 100% for the participants with disabilities. Satisfaction was between 3.4 and 5.0 (max.) for the participants without disability and between 2.8 and 5.0 for the participants with disabilities. Overall the input by standard devices such as keyboard and mouse had better usability than the more complex devices like eye gazing technology. Comparable types of control (head control, eye control) also had similar usability. The usability dimensions of efficiency, effectiveness and satisfaction with input aids as examined in this study could be evaluated in the process of recommending communication and writing aids. The focus should however not only be on the input aids as such, but also include all optimization options such as word prediction and auto text.

AB - Stellera chamaejasme, also known as "Langdu", has been traditionally used for the management of skin-related diseases such as psoriasis and skin ulcers. The aim of this study was to determine whether S. chamaejasme and its major component, luteolin 7-O-glucoside, have a preventive effect on the development of atopic dermatitis in oxazolone-treated BALB/c mice and 2,4-dinitrochlorobenzene-treated hairless mice. The epicutaneous applications of oxazolone and 2,4 dinitrochlorobenzene evoke an experimental murine atopic dermatitis-like reaction in BALB/c mouse ears and SKH-1 hairless mice. Atopic skin symptoms, including erythema (redness), pruritus (itching), exudation (weeping), excoriation (peeling), and lichenification (skin thickening), responded to treatment with S. chamaejasme aerial parts EtOH extract for 2 or 3 weeks. Histopathological examination revealed S. chamaejasme aerial parts EtOH extract significantly reduced inflammatory cell infiltration when applied to atopic dermatitis mice. In addition, luteolin 7-O-glucoside, the major active compound of the S. chamaejasme aerial parts EtOH extract, decreased serum IgE and IL-4 levels and transepidermal water loss and increased skin hydration, therefore exhibiting strong anti-atopic dermatitis activity in 2,4-dinitrochlorobenzene-induced atopic dermatitis mice. In this study, we confirmed antipruritic and antidermatitic effects of S. chamaejasme extract and its main component luteolin 7-O-glucoside in atopic dermatitis murine models. The study shows S. chamaejasme aerial parts EtOH extract and luteolin 7-O-glucoside are most likely to be potential drug candidates for atopic dermatitis treatment.

AB - Long-term outcome after joint bleeds in von Willebrand disease (VWD) (von Willebrand factor activity <= 30 IU/dL) could differ from moderate or severe haemophilia A (HA) (factor VIII [FVIII] 1-5 IU/dL or FVIII < 1 IU/dL). We performed a post hoc analysis on Haemophilia Joint Health Score (HJHS, 0-124), X ray Pettersson scores (PS, 0-13/joint) and the Haemophilia Activities List (HAL, 0-100), using multivariable regression to adjust for age (rate ratio [RR] or odds ratio [OR] [95% confidence interval]). We included 48 VWD (median age, 47 years, type 3 VWD, n = 19), 39 moderate HA (median, 39 years) and 59 severe HA patients (median, 25 years) with documented joint bleeds. VWD patients suffered repeated bleeding (lifetime > 5/joint) less often than moderate and severe HA patients (52% vs. 77% vs. 98%). HJHS and PS in VWD were similar to moderate HA (median HJHS 5 vs. 6, RR 0.9 [0.5-1.4] and PS > 3 of >= 1 joint OR 0.3 [0.1-1.4]), but better than in severe HA patients (median HJHS 5 vs. 9, RR 1.8 [1.1-2.9]; PS > 3 in any joint OR 0.1 [0.0-0.3]). Self-reported limitations in activities were comparable across VWD, moderate HA (HAL score < 95: 67% vs. 49%; OR 1.4 [0.5 3.6]) and young adults with severe HA (67% vs. 48%; OR 1.7 [0.7-4.4]). Despite fewer joint bleeds, joint outcome after joint bleeds was similar in VWD and moderate HA patients. Type 3 VWD patients had worst joint outcome, comparable to younger intensively treated severe HA patients. Limitations in activities occurred as often in VWD as in both moderate and severe HA. PMID- 30273955 TI - Evaluation of human observer performance on lesion detectability in single-slice and multislice dedicated breast cone beam CT images with breast anatomical background. AB - PURPOSE: We evaluate the lesion detectability using human and model observer studies in single-slice and multislice cone beam computed tomography (CBCT) images with a breast anatomical background. The purposes of this work are (a) to compare human observer detectability between single-slice and multislice images for different signal sizes and noise structures, (b) to investigate the effect of different multislice viewing modes (i.e., sequential and simultaneous) on the detectability by a human observer, and (c) to predict the detectability by a human observer in single-slice and multislice images using single-slice channelized Hotelling observer (ssCHO) and multislice CHO (msCHO), respectively. METHODS: Breast anatomical background is modeled using a power law spectrum of mammograms and the lesion is modeled with a spherical signal. We conduct signal known-exactly and background-known-statistically detection tasks on transverse and longitudinal images reconstructed using the Feldkamp-Davis-Kress algorithm with Hanning and Ram-Lak weighted ramp filters. The human observer study is conducted on three different viewing modes: single-slice, and sequential and simultaneous multislice. To predict the detectability by a human observer, we use ssCHO and msCHO with anthropomorphic channels (i.e., dense difference-of-Gaussian (D-DOG) and Gabor channels) and internal noise. RESULTS: The detectability by a human observer increases for multislice images compared to single-slice images. For multislice images, the sequential viewing mode yields higher detectability than the simultaneous viewing mode. However, the relative rank of detectability by a human observer for different signal sizes, image planes, and reconstruction filters is not much different between the viewing modes. Detectability by CHO with internal noise shows good correlation with that of the human observer for all viewing modes. CONCLUSIONS: Detectability by a human observer in CBCT images with breast anatomical background is affected by the image viewing mode, and the effect of the viewing mode depends on the signal size and noise structure. D-DOG and Gabor CHO with internal noise predict the detectability by a human observer well for both the single-slice and multislice image viewing modes. PMID- 30273956 TI - Interwealth Contact and Young Children's Concern for Equity. AB - This study examined young children's contact with individuals of high-wealth and low-wealth backgrounds and their behavior toward peers of these backgrounds in a resource distribution task. The sample included 72 ethnically diverse higher income children (Mage = 6.68 years, SD = 0.98 years). Contact with individuals of low-wealth backgrounds (interwealth contact) affected children's behavior indirectly, through social-cognitive reasoning processes. The more interwealth contact children reported, the more likely they were to reason about access to resources rather than their own wealth preferences in this context. This reasoning, in turn, was associated with more resources allocated to a low-wealth peer relative to a high-wealth peer. Thus, interwealth contact early in development was associated with more equitable peer interactions. PMID- 30273957 TI - High-precision noise power spectrum measurements in digital radiography imaging. AB - PURPOSE: Accurately and precisely estimating the noise power spectrum (NPS) is important for characterizing the performance of a radiography detector and helpful for improving the performance when developing radiography detectors. In order to produce an accurate estimate, the frequency resolution should be sufficiently high, and for a precise estimate, the sample size for the sample mean should also be large enough. However, there is a trade-off between the frequency resolution and the sample size if the available samples are limited. To improve the precision of the estimate, a radial averaging technique is employed in the IEC standard without sacrificing the frequency resolution or the estimate accuracy. In the radial averaging technique, directional NPS curves of a range are averaged from the two-dimensional NPS, and thus, directional error and poor precision problems occur, especially at low frequencies. This problem also leads to uncertainties in calculating the detective quantum efficiency (DQE). Therefore, the purpose of this study is to develop algorithms that can improve the precisions in estimating NPS to replace the radial averaging technique or to add additional precision. METHODS: The horizontal or vertical NPS curve can be estimated using the sample mean of the summation of directional cross periodograms with various distances from the two-dimensional NPS. In practical x ray imaging, the amplitude response of the cross periodograms decreases rapidly as the distance increases. Hence, a partial summation of the cross periodograms can provide an accurate estimate of the NPS. This partial summation can increase the sample size and thus improve the estimate precision for the entire frequency range without causing directional errors. This paper proposes two estimate algorithms under the notion of the partial use of cross periodograms. RESULTS: In order to evaluate the precisions from the proposed algorithms, a relative precision, which is defined as the standard deviation of the estimate divided by its average, was employed. The relative precisions were calculated using 100 x ray images acquired from a general radiography detector. For the detector, we were able to achieve a better precision compared to using the radial averaging technique. For an image of 900 * 900 pixels and the region of interest size 256 in a direction with a half overlap, the conventional approach of the IEC standard yielded an average relative precision of 6.96% with the worst precision of 36.1% at the zero frequency. However, the proposed algorithms could yield an average relative precision of 4.14% with the zero-frequency precision of 5.79%. CONCLUSIONS: Without using the radial averaging technique, the proposed algorithms in this paper could improve the estimate precisions for the entire frequency range under the notion of a partial summation of the cross periodograms. Especially for low frequencies including the zero frequency, the proposed algorithms could achieve a high-precision to estimate the NPS. PMID- 30273958 TI - Self-rated health, symptoms and health behaviour of upper secondary vocational students by field of study. AB - This article examines the self-rated health, symptoms and health behaviour of upper secondary vocational students in Finland. The data consist of the responses of first- and second-year vocational students (n = 34 554) to the 2013 School Health Promotion Survey. The data were analysed statistically and processed separately for girls and boys. Associations between self-rated health, symptoms and health behaviour and fields of study were examined by cross-tabulation. Statistical significance was measured using the chi-squared test. Self-rated health, symptoms and health behaviour were found to have a statistically significant association with field of study (p < 0.001). Vocational students in different fields had different experiences of health, different symptoms and different health behaviours. The results complement existing evidence about disparities in well-being among young people in the context of education. PMID- 30273959 TI - Hemodynamic Evaluation of Avalon Elite Bi-Caval Dual Lumen Cannulas and Femoral Arterial Cannulas. AB - Translational research is a useful tool to provide scientific evidence for cannula selection during extracorporeal life support (ECLS). The objective of this study was to evaluate four Avalon Elite bi-caval dual lumen cannulas and nine femoral arterial cannulas in terms of flow range, circuit pressure, pressure drop, and hemodynamic energy transmission in a simulated adult ECLS model. A veno venous ECLS circuit was used to evaluate four Avalon Elite bi-caval dual lumen cannulas (20, 23, 27, and 31 Fr), and a veno-arterial ECLS circuit was used to evaluate nine femoral arterial cannulas (15, 17, 19, 21, and 23 Fr). The two circuits included a Rotaflow centrifugal pump, a Quadrox-D adult oxygenator, and 3/8 in ID tubing for arterial and venous lines. The circuits were primed with lactated Ringer's solution and packed human red blood cells (hematocrit 40%). Trials were conducted at rotational speeds from 1000 to 5000 RPM (250 rpm increments) for each Avalon cannula, and at different flow rates (0.5-7 L/min) for each femoral arterial cannula. Real-time pressure and flow data were recorded for analysis. Small caliber cannulas created higher circuit pressures, higher pressure drops and higher M-numbers compared with large ones. The inflow side of Avalon dual lumen cannula had a significantly higher pressure drop than the outflow side (inflow vs. outflow: 20 Fr-100.2 vs. 49.2 mm Hg at 1.1 L/min, 23 Fr 93.7 vs. 41.4 mm Hg at 1.6 L/min, 27 Fr-102.3 vs. 42.8 mm Hg at 2.6 L/min, 31 Fr 98.1 vs. 44.7 mm Hg at 3.8 L/min). There was more hemodynamic energy lost in the veno-arterial ECLS circuit using small cannulas compared to larger ones (17 Fr vs. 19 Fr vs. 21 Fr at 4 L/min-Medtronic: 71.0 vs. 64.8 vs. 60.9%; Maquet: 71.4 vs. 65.6 vs. 62.0%). Medtronic femoral arterial cannulas had lower pressure drops (Medtronic vs. Maquet at 4 L/min: 17 Fr-121.7 vs. 125.0 mm Hg, 19 Fr-71.2 vs. 73.7 mm Hg, 21 Fr-42.9 vs. 47.4 mm Hg) and hemodynamic energy losses (Medtronic vs. Maquet at 4 L/min: 17 Fr-43.6 vs. 44.4%, 19 Fr-31.0 vs. 31.4%, 21 Fr-20.8 vs. 22.4%) at high flow rates when compared with the Maquet cannulae. The results for this study provided valuable hemodynamic characteristics of all evaluated adult cannulas with human blood in order to guide ECLS cannula selection in clinical practice. Use of larger cannulas are suggested for VV- and VA-ECLS. PMID- 30273960 TI - Novel mutation in Teneurin 3 found to co-segregate in all affecteds in a multi generation family with developmental dysplasia of the hip. AB - DDH is a debilitating condition characterized by incomplete formation of the acetabulum leading to dislocation of the hip, suboptimal joint function and accelerated wear of the articular cartilage resulting in early onset crippling arthritis of the hip in 20-40 year olds. Current diagnostic tests in newborns using physical manipulation of the femur or ultrasound either under or over diagnose this condition. Developing an accurate, cost effective diagnostic test is a goal of this study. To better understand the biologic pathways involved in acetabular development, DNA from severely affected individuals in a four generation family that showed inter-generational transmission of the disorder was isolated and whole exome sequenced. A novel A to C transversion at position 183721398 on human chromosome four was found to co-segregate with the affected phenotype in this family. This mutation encodes a glutamine to proline change at position 2665 in the Teneurin 3 (TENM3) gene and was judged damaging by four prediction programs. Eight week old knock-in mutant mice show delayed development of the left acetabulum and the left glenoid fossa as shown by the presence of more Alcian blue staining on the socket rims of both the hip and the shoulder. We hypothesize that mutated TENM3 will slow chondrogenesis. MMP13 has been shown to impair extracellular matrix remodeling and suppress differentiation. Bone marrow cells from the knock-in mouse were found to overexpress MMP13 with or without BMP2 stimulation. This variant may elucidate pathways responsible for normal hip development and become part of an accurate test for DDH. (c) 2018 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

AB - This study aimed to investigate the effect of chrysin on colistin-induced reproductive toxicity. Twenty-eight adult male Sprague-Dawley rats were divided into four groups of seven rats each. Group I received physiological saline for 7 days. Group II received 50 mg/kg/day chrysin for 7 days. Group III received a total dose of 73 mg/kg colistin for 7 days. Group IV received 50 mg/kg/day chrysin by an oral gavage after the colistin treatment. Colistin causes an increase in oxidative stress (OS) in the testis. Chrysin treatment significantly decreased the OS in the chrysin + colistin group compared with the colistin group. The highest caspase-3 and LC3B expression levels were found in the colistin group and these levels were statistically lower in the chrysin + colistin group. Colistin treatment caused a decrease in sperm motility and an increase in sperm abnormality. Chrysin treatment mitigated these side effects significantly. In conclusion, chrysin treatment can be beneficial against colistin-induced reproductive toxicity. PMID- 30273962 TI - p-Hydroxybenzyl alcohol inhibits four obesity-related enzymes in vitro. AB - Recently, antiobesity studies using the method of inhibiting enzymatic activity of obesity-related enzymes as targets have received considerable attention. The aims of the current study were to investigate whether p-hydroxybenzyl alcohol (HBA), identified from Cudrania tricuspidata fruits with antiobesity effects, inhibits the activity of digestive and obesity-related enzymes and acts as an inhibitor against four target enzymes in kinetic studies. In vitro enzyme assays showed HBA at the highest concentration significantly reduced the enzymatic activity of four targets: pancreatic lipase (IC50 = 2.34-3.70 MUM), alpha glycosidase (IC50 = 9.08 MUM), phosphodiesterase IV (IC50 = 4.99 MUM), and citrate synthase (IC50 = 2.07 MUM) enzymes. Based on the results of kinetic assays, the types of inhibition were investigated. Our findings indicate that HBA could have antiobesity efficacy, and it deserves further study. PMID- 30273963 TI - A circular echo planar sequence for fast volumetric fMRI. AB - PURPOSE: To demonstrate a circular EPI (CEPI) sequence as well as a generalized EPI reconstruction for fast fMRI with parallel imaging acceleration. METHODS: The CEPI acquisition was constructed using variable readout lengths and maximum ramp sampling as well as blipped-CAIPI z-gradient encoding for simultaneous multislice (SMS) and 3D volumetric imaging. A signal equation model with constant and linear phase terms was used to iteratively reconstruct images with low ghosting. Simulation, phantom, and human imaging experiments including audio/visual fMRI were performed at 3T using a 52-channel coil. RESULTS: Application of CEPI gradients with duration of 27 ms covering a 22-cm FOV at a 64 * 64 pixel resolution in SMS and 3D acquisitions resulted in images with comparable quality to those of standard Cartesian EPI. With parallel imaging techniques robust detection of BOLD fMRI activation with temporal sampling down to 275 ms was possible. The high temporal resolution enabled higher activation statistics at a penalty in increased noise and residual aliasing. The un-accelerated 3D acquisition showed large temporal instability compared with a standard 2D acquisition. CONCLUSION: Nonuniform sampling and generalized image reconstructions can be applied to EPI acquisitions including those with blipped CAIPI z gradients. The same gradients can be used for either SMS or 3D acquisitions providing identical coverage. PMID- 30273964 TI - Oligomeric proanthocyanidins mitigate cholesterol and cholic acid diet-induced hepatic dysfunction in male Sprague Dawley rats. AB - Dysregulated synthesis of hepatic cholesterol is a critical determinant of atherosclerosis. The combination of cholesterol and cholic acid (CC) diet supplementation to animal models is associated with hepatic dysfunction-mediated atherosclerosis. The current study was designed to investigate the hepatic cholesterol-lowering effects of oligomeric proanthocyanidins (OPC) in CC diet fed rats. CC diet-induced group exhibited significant increase in the hepatic lipid profile, activities of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase (HMGR), PON-1, LCAT, LPL, and LPO levels, and messenger RNA expression of HMGR, low-density lipoprotein receptor (LDLr), and HNF-4alpha. Administration of OPC (100 mg/kg/bwt) resulted in the significant reduction of lipid profile and HMGR levels, with concomitant increase in the levels of cholesterol-regulating enzymes and upregulated expression of LDLr and HNF-4alpha, which was similar to atorvastatin. Molecular docking studies also revealed that proanthocyanidins had a strong binding affinity to HMGR, similar to atorvastatin. Our findings suggest that OPC regulate the impaired cholesterol metabolism-associated atherosclerosis through hepatic cholesterol-lowering effect. PMID- 30273965 TI - A predictive algorithm for spot position corrections after fast energy switching in proton pencil beam scanning. AB - PURPOSE: Fast energy switching is of fundamental importance to implement motion mitigation techniques in pencil beam scanning proton therapy, allowing efficient irradiation and high patient throughput. However, depending on magnet design, when switching between different energy layers, eddy currents arise in the bending magnets' yoke, damping the speed of the magnetic field change and lengthening the settling time of the magnetic field. In a proton therapy gantry, this can cause a temporary displacement of the beam trajectory and consequently an incorrect beam position in the bending direction, resulting in an unacceptable loss of position precision at isocenter. The precision can be recovered by either increasing the beam off time after an energy change (waiting until the magnetic field is fully settled) or by actively correcting for the misplacement. We studied the transient magnetic field effects at PSI Gantry 2 in order to develop a correction strategy for this beam position misplacement. METHODS: We used position and proton range sensitive detectors (segmented strip chamber and multilayer ionization chambers respectively) to measure the difference between expected and actual proton beam position and range as a function of time. The detectors are automatically triggered, read out, and analyzed by the treatment control system. We studied the effects due to the magnets on the gantry and those upstream of the gantry separately, in order to identify which elements contribute the most to the beam position instability. We then designed a spot position algorithm to be applied with the gantry scanning magnets, to correct for the displacement observed as a function of time and achieve the PSI Gantry 2 clinical target of 1 mm precision at isocenter at all times, even after an energy change. RESULTS: When switching energy layers in a field, we observed an exponentially decaying spot position displacement at isocenter. The effect increases with increasing energy difference between energy layers (DeltaE). The initial residuals between expected and measured position are higher than 1 mm for most of the clinical cases at Gantry 2 and fall below 1 mm within about 1 s or more (depending on DeltaE). We found no time dependence for the proton range, thus confirming that the displacement is purely due to a beam trajectory displacement resulting from the longer settling time of the magnetic field. A double exponential model, with two time constants and amplitudes depending on DeltaE, fits the data and provides an easy model for the correction function. We implemented this correction as a spot position correction, applied by the scanning magnets during field application. After correction, the residuals were below 0.5 mm right after the energy change. CONCLUSIONS: We developed a spot position correction for PSI Gantry 2 which reduces the beam off time needed in current state-of-the-art gantries to settle the magnetic fields in the bending magnets. Thanks to this correction, the spot position is stable within 100 ms of an energy change at Gantry 2. This is low enough to make possible efficient use of motion mitigation techniques. PMID- 30273967 TI - A cost-effectiveness threshold based on the marginal returns of cardiovascular hospital spending. AB - Traditionally, threshold levels of cost-effectiveness have been derived from willingness-to-pay studies, indicating the consumption value of health (v thresholds). However, it has been argued that v-thresholds need to be supplemented by so-called k-thresholds, which are based on the marginal returns to health care. The objective of this research is to estimate a k-threshold based on the marginal returns to cardiovascular disease (CVD) hospital care in the Netherlands. To estimate a k-threshold for hospital care on CVD, we proceed in two steps: First, we estimate the impact of hospital spending on mortality using a Bayesian regression modelling framework, using data on CVD mortality and CVD hospital spending by age and gender for the period 1994-2010. Second, we use life tables in combination with quality of life data to convert these estimates into a k-threshold expressed in euros per quality-adjusted life year gained. Our base case estimate resulted in an estimate of 41,000 per quality-adjusted life year gained. In our sensitivity analyses, we illustrated how the incorporation of prior evidence into the estimation pushes estimates downwards. We conclude that our base case estimate of the k-threshold may serve as a benchmark value for decision making in the Netherlands as well as for future research regarding k thresholds.

In multiple cancers, ZEB1 serves as a transcription activator to regulate gene expression. We explored the roles of ZEB1 in HBXIP-induced breast cancer growth. METHODS: HBXIP regulation of ZEB1 was evaluated by reverse transcription PCR and immunoblotting. The stimulation of ZEB1 promoter by HBXIP and/or Sp1 was tested using luciferase reporter gene analysis. The alteration of cell proliferation mediated by HBXIP-induced ZEB1 was tested using methyl thiazolyl-tetrazolium and 5-Ethynyl-2'-deoxyuridine (EdU) incorporation analysis. ZEB1 and HBXIP expression in human breast cancer tissues was analyzed using quantitative real-time PCR. The relationship between HBXIP and ZEB1 was confirmed by Pearson's correlation coefficient. RESULTS: We observed dose-dependent upregulation of ZEB1 by HBXIP in breast cancer cells. HBXIP can activate the ZEB1 promoter by interacting with transcription factor Sp1. Cell viability and EdU incorporation analysis showed that HBXIP could drive cell proliferation by enhancing ZEB1 in breast cancer. Using quantitative real-time PCR, ZEB1 overexpression and a positive relationship between ZEB1 and HBXIP were observed in clinical breast cancer samples. CONCLUSION: Oncogenic HBXIP controls the transcription regulation of ZEB1 by co-activating Sp1, thereby accelerating breast cancer growth. PMID- 30273968 TI - Translation of morphological and functional musculoskeletal imaging. AB - In an effort to develop quantitative biomarkers for degenerative joint disease and fill the void that exists for diagnosing, monitoring, and assessing the extent of whole joint degeneration, the past decade has been marked by a greatly increased role of noninvasive imaging. This coupled with recent advances in image processing and deep learning opens new possibilities for promising quantitative techniques. The clinical translation of quantitative imaging was previously hampered by tedious non-scalable and subjective image analysis. Osteoarthritis (OA) diagnosis using X-rays can be automated by the use of deep learning models and pilot studies showed feasibility of using similar techniques to reliably segment multiple musculoskeletal tissues and detect and stage the severity of morphological abnormalities in magnetic resonance imaging (MRI). Automation and more advanced feature extraction techniques have applications on larger more heterogeneous samples. Analyses based on voxel based relaxometry have shown local patterns in relaxation time elevations and local correlations with outcome variables. Bone cartilage interactions are also enhanced by the analysis of three dimensional bone morphology and the potential for the assessment of metabolic activity with simultaneous Positron Emission Tomography (PET)/MR systems. Novel techniques in image processing and deep learning are augmenting imaging to be a source of quantitative and reliable data and new multidimensional analytics allow us to exploit the interactions of data from various sources. In this review, we aim to summarize recent advances in quantitative imaging, the application of image processing and deep learning techniques to study knee and hip OA.

The decline of self-control in middle childhood. AB - OBJECTIVE: This study examined the developmental change in self-control and its association with daily stressful events during middle childhood, as well as the factors that contribute to individual differences in the trajectory of self control. METHOD: A community sample of 302 Singaporean children (42% female, 69% Chinese) and their parents were recruited when the children were age 7. Follow-up assessments were made when the children were ages 8, 9, and 11. Developmental changes were examined using latent growth and autoregressive cross-lagged models. RESULTS: Self-control showed a normative decline over time, and this trajectory was associated with an increase in daily stressful events. There was partial evidence for a reciprocal relationship between self-control and daily stressful events over time. Moreover, the child temperament dimension of effortful control (assessed at age 7) mitigated the decline in self-control, whereas low socioeconomic status predicted lower initial levels of self-control. CONCLUSIONS: This study advances current understanding on the developmental change in self control during middle childhood, as well as the factors that shape the direction and magnitude of this change. PMID- 30273970 TI - Age at referral for diagnosis and rehabilitation services for cerebral palsy: a scoping review. AB - AIM: This study sought to: (1) determine what is known about age at referral for diagnosis and rehabilitation services for children suspected of having cerebral palsy (CP); and (2) identify factors associated with earlier referral. METHOD: A scoping review was conducted to summarize existing literature. We systematically searched Allied and Complementary Medicine, CINAHL, Cochrane Library, Embase, and PsycINFO for evidence published between 1979 and 2017 on age at referral for diagnosis or age at referral to rehabilitation services for children suspected of having CP. Quantitative and thematic analyses of the literature were performed. RESULTS: Our search yielded 777 articles, of which 15 met the inclusion criteria. Only one study focused on age at referral for diagnosis of CP (mean 16.6mo+/ 19.2mo), with two on age at referral to rehabilitation services (means 13.9mo+/ 15.8mo and 12.4mo). Potential predictors of earlier referral identified include referral source, type of CP, and a complicated birth history. INTERPRETATION: Evidence is sparse; however, available studies suggest high variation in the age at which children are being referred for diagnosis, typically ranging from 10 months to 21 months. Evidence indicates that subgroups of children with CP might be experiencing prolonged delays. Findings highlight the need to better understand what contributes to delays in referral for diagnosis and rehabilitation. WHAT THIS PAPER ADDS: Evidence on age at referral for diagnosis of cerebral palsy is sparse. Potential predictors of delayed referral represent targets to minimize delays in diagnosis. A subset of children may be experiencing unnecessary delays in referral. PMID- 30273971 TI - Agmatine protects against sodium valproate-induced hepatic injury in mice via modulation of nuclear factor-kappaB/inducible nitric oxide synthetase pathway. AB - Valproate is a widely used drug against epilepsy and several other neurological disorders although it has deleterious hepatotoxic side effects. The current study was designed to test if agmatine as nitric oxide modulator has protective effects against valproate-induced hepatic injury. Male Swiss albino mice were treated with sodium valproate (SVP) with or without agmatine for 7 days. Serum and liver samples were collected for analysis. Results have revealed that agmatine exerted hepatoprotective effects against SVP-associated hepatic injury. Agmatine ameliorated SVP-induced elevated serum biochemical markers of hepatic damage such as serum transaminases, alkaline phosphatase, gamma-glutamyl transferase, and lactate dehydrogenase. Histopathological examination of the liver showed improvement of hepatic lesions in case of agmatine treatment. Furthermore, agmatine attenuated oxidative stress and enhanced antioxidants in liver tissue. Agmatine inhibited the activation of nuclear factor-kappaB and ameliorated the immunoexpression of inducible nitric oxide synthetase. This was accompanied by decrease in the level of inflammatory markers as nitrite/nitrate, tumor necrosis factor-alpha, and interleukin-6. These data provide new evidence of the hepatoprotective activity of agmatine against SVP-induced hepatotoxic effects. PMID- 30273972 TI - Antibacterial activities of plasma from the common (Chelydra serpentina) and alligator snapping turtle (Macrochelys temminckii). AB - Innate immunity provides a fast-acting and nonspecific defense against microbial infection, and appears to have particular importance in the immune response of ectothermic vertebrates. Chelonians are a globally distributed and diverse group, yet little is known about their basic immune function. The chelonian family Chelydridae is made up of two genera (Chelydra and Macrochelys), represented in our study by the widespread common snapping turtle ( Chelydra serpentina; CST) and the southeast USA endemic alligator snapping turtle ( Macrochelys temminckii; AST). Our goal was to quantify the innate immune response of the family Chelydridae, using the antibacterial activity of plasma as a measure of immune function. Our results show that the plasma of both species has strong antibacterial properties, but CST plasma kills a higher percentage of bacteria than AST plasma. In addition, while both species showed the highest antibacterial activity at 25 to 30 degrees C, CST plasma retained its antibacterial properties at lower and higher temperatures than AST plasma. Our results indicate that, like many ectotherms, Chelydridae have a relatively strong innate immune response. The stronger, more robust immune response of CSTs compared with ASTs is likely correlated to the differences in geographic ranges but may also have implications for each species' tolerance to anthropogenic habitat degradation and global climate change. PMID- 30273973 TI - Follicular development of canine ovaries stimulated by a combination treatment of eCG and hCG. AB - Ovarian follicular dynamics is not well known in dogs. Imaging of ovaries is technically difficult; however, ovaries clamped at a subcutaneous site can more easily be monitored using ultrasound imaging. This study investigated the follicular development of canine ovaries stimulated by hormone treatment using ultrasound imaging of the ovaries clamped at a subcutaneous site. Oestrus was induced using subcutaneous administration of 500 IU equine chorionic gonadotropin (eCG) and 1000 IU human chorionic gonadotropin (hCG) (eCG/hCG). Five bitches were given 1000 IU hCG 11 days after eCG/hCG administration. Examinations with ovarian ultrasonography using a 7.5-MHz sector transducer, vaginal cytology, and assays of serum oestrogen and progesterone were performed daily until 20 days after eCG/hCG administration. Serosanguineous vaginal discharges and vaginal cytology of two of the bitches were observed. New follicular growth (>1.0 mm in diameter) was observed in all bitches from 2 to 8 days after eCG/hCG administration. The mean diameter of follicles and maximum numbers of follicles per ovary ranged from 2.8 to 5.5 mm and 4 to 16, respectively. The elevation in oestrogen concentrations after eCG/hCG administration was observed in all bitches, and elevation in progesterone concentration (>2 ng mL-1 ) was observed in three bitches. However, no follicles ovulated until 9 days after hCG administration. In conclusion, although the number of examined bitches were limited, follicular growth in ovaries clamped at a subcutaneous site can be monitored using ultrasound imaging. Ovarian ultrasonography showed that eCG/hCG administration induced new follicular growth and hCG administration induced increases in oestrogen concentrations but not ovulation by hCG administration. PMID- 30273974 TI - Sleep Problems in Adults With Autism Spectrum Disorder and Intellectual Disability. AB - : Sleep problems (SP) are recognized as a common comorbid condition in autism spectrum disorder (ASD) and can influence core autism symptoms and mental and physical health. SPs can be lifelong and have been reported that adults on the autistic spectrum with and without intellectual disability (ID) present SPs (longer sleep latency, frequent night awakenings, and circadian rhythm sleep-wake disorders). A prospective, objective sleep study was conducted in 41 adults with ASD (33 +/- 6 years old) and ID and 51 typically developing adults (33 +/- 5 years old) using ambulatory circadian monitoring (ACM) recording wrist temperature, motor activity, body position, sleep, and light intensity. The findings indicated that individuals with ASD presented sleep difficulties including low sleep efficiency, prolonged sleep latency and increased number and length of night awakenings, together with daily sedentary behavior, and increased nocturnal activity. Furthermore, indications of an advanced sleep-wake phase disorder were found in these autistic adults. Examining sleep and markers of the circadian system showed significant differences between adults with ASD and ID and an age-matched, healthy adult population. The sleep disturbances described for this sample of adults with ASD and ID are similar to those of already described for adults with ASD without ID; their relationship with intellectual ability should be further studied. Improving knowledge of sleep patterns in ASD adults with ID might help to designed targeted interventions to improve their functioning and reduce family stress. Autism Res 2018. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: SPs are very frequent in autism from childhood to adulthood. We recorded sleep with a watch like device in adults with autism and ID and compared sleep patterns with nonautistic volunteers. Results showed poorer sleep conditions in adults with autism (increased sleep latency and number/length of night awakenings) that resulted in decreased sleep efficiency. Increasing knowledge of the SPs in adults on the autism spectrum will allow to improve their and their families' quality of life. PMID- 30273975 TI - Experimental study of needle recording electrodes placed on the thyroid cartilage for neuromonitoring during thyroid surgery. AB - BACKGROUND: Needle electrodes placed on the thyroid cartilage (TC) are an alternative to endotracheal tube (ET) electrodes for assessing recurrent laryngeal nerve (RLN) function during thyroid surgery. Needle electrodes placed on the TC were evaluated in an experimental porcine model. METHODS: Continuous intraoperative neuromonitoring was used to record the electromyogram. Each TC side was delineated into nine areas to determine the optimal placement of the electrode, and needle electrode area, depth and orientation for optimal electromyographic (EMG) amplitudes were evaluated. RLN root locations were stimulated at four locations: vagus nerve distal to the neuromonitoring electrode, and most proximal, middle and laryngeal entry points of the nerve. A nerve retraction injury model was adapted to compare RLN monitoring by TC versus ET electrodes. RESULTS: An optimal site for placement of needle electrodes was identified, and electromyograms obtained from the various needle insertion depths and orientations were similar. Latencies recorded from the TC and ET electrodes were similar. The amplitude profile of TC electrodes responded earlier to RLN injury than that of ET electrodes. Amplitude and drop to loss of signal were also registered earlier. CONCLUSION: EMG amplitudes obtained using TC electrodes were higher, and identified RLN injury earlier than ET electrodes. Surgical relevance Needle electrodes placed on the thyroid cartilage (TC) are an alternative to endotracheal tube (ET) electrodes for assessing the function of the recurrent laryngeal nerve (RLN) in thyroid surgery. This study used an experimental porcine model to evaluate the use of needle electrodes inserted in the TC, compared with ET electrodes, for producing an electromyographic (EMG) profile of the RLN. Nine areas of the TC, with various needle insertion depths and orientations, were compared. Perichondral insertion into the avascular area of the TC was found to be safe. The EMG amplitude and latency features recorded via the TC and ET electrodes were compared, using both intermittent and continuous monitoring. Changes in EMG amplitudes in response to nerve traction injury were registered earlier with TC electrodes than with ET electrodes, and the amplitudes were higher and more stable. Latencies obtained via the TC and ET electrodes were similar. These results indicate that the development of a non-invasive monitoring electrode with improved function, easy placement and low cost is possible. PMID- 30273976 TI - Physician characteristics, industry transfers, and pharmaceutical prescribing: Empirical evidence from medicare and the physician payment sunshine act. AB - OBJECTIVE: To evaluate physician characteristics associated with pharmaceutical industry transfers and prescribing behavior after public reporting under the Sunshine Act. DATA SOURCES: 2014-2016 secondary data on industry transfers to physicians from the Open Payments Dataset supplemented with Medicare Part D prescription data, Medicare service data, and practice attributes from the Physician Compare Database. STUDY DESIGN: Using regression analysis with county/physician fixed effects, this study examines characteristics associated with the probability/magnitude of transfers and the association between transfers and prescriptions. DATA COLLECTION: Using an iterative matching approach, this study identifies physicians who delivered outpatient Medicare services in 2014 (n = 409 041) and tracks their annual transfers between 2014 and 2016 (N = 1 227 123) across six transfer categories. In addition, it examines their Medicare Part D prescription behavior between 2014 and 2015 (N = 741 659). PRINCIPAL FINDINGS: Industry transfers dramatically declined in 2015 and 2016. Transfers are significantly associated with increased prescription costs, branded prescribing, and prescribing for High-Risk Medications (HRMs). CONCLUSIONS: Industry transfers have declined after public reporting. Transfers are associated with higher prescription costs and incidence of HRMs. Future research is needed to determine the causal impact on quality and cost-effectiveness of prescribed medications. PMID- 30273977 TI - Preclinical induced membrane model to evaluate synthetic implants for healing critical bone defects without autograft. AB - Critical bone defects pose a formidable orthopaedic problem in patients with bone loss. We developed a preclinical model based on the induced membrane technique using a synthetic graft to replace autograft for healing critical bone defects. Additionally, we used a novel osteoconductive scaffold coupled with a synthetic membrane to evaluate the potential for single-stage bone regeneration. Three experimental conditions were investigated in critical femoral defects in rats. Group A underwent a two-stage procedure with insertion of a polymethylmethacrylate (PMMA) spacer followed by replacement with a 3D printed polycaprolactone(PCL)/beta-tricalcium phosphate (beta-TCP) osteoconductive scaffold after 4 weeks. Group B received a single-stage PCL/beta-TCP scaffold wrapped in a PCL-based microporous polymer film creating a synthetic membrane. Group C received a single-stage bare PCL/beta-TCP scaffold. All groups were examined by serial radiographs for callus formation. After 12 weeks, the femurs were explanted and analyzed with micro-CT and histology. Mean callus scores tended to be higher in Group A. Group A showed statistically significant greater bone formation on micro-CT compared with other groups, although bone volume fraction was similar between groups. Histology results suggested extensive bone ingrowth and new bone formation within the macroporous scaffolds in all groups and cell infiltration into the microporous synthetic membrane. This study supports the use of a critical size femoral defect in rats as a suitable model for investigating modifications to the induced membrane technique without autograft harvest. Future investigations should focus on bioactive synthetic membranes coupled with growth factors for single-stage bone healing. (c) 2018 Orthopaedic Research Society.

AB - Children with autism spectrum disorder (ASD) are at a higher risk of having obesity than their typically developing peers. Although it has been recommended that health care providers (HCPs) speak to caregivers and children about the risk of higher weights, no research has examined how HCPs communicate weight-related information. Furthermore, there is a dearth of evidence regarding how to approach and deliver optimal weight-related discussions among children with ASD and their caregivers. Given these knowledge gaps, 21 in-depth interviews were conducted with children with ASD, their caregivers, and HCPs. Using a qualitative analytic approach, data from interviews were analyzed thematically. Results suggest that HCPs at times projected weight stigma during clinical encounters, which did not motivate children and caregivers to work toward work loss or wellness. HCPs also described reticence in engaging families in weight-related conversations due to limited training, and lack of clinical tools to guide these conversations. All stakeholders identified a need to work together to establish a therapeutic partnership to discuss weight-related issues without blame or shame. The combination of strength-based communication approaches, establishing a strong therapeutic partnership, and development of clinical tools facilitating weight related discussions for HCPs outlined in this article are potential vehicles to foster successful weight-related discussions while promoting lifelong wellness. Autism Research 2018, 11: 1500-1510. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Children with autism spectrum disorder (ASD) are at a higher risk of having obesity. Yet, it is unknown how healthcare providers (HCPs) should deliver weight-related information. Findings suggest children and caregivers experienced weight stigma and were uncomfortable discussing weight-related issues. HCPs identified that they did not have sufficient training, and did not feel confident identifying/addressing weight issues. Tools are needed to facilitate weight-related discussions among children, caregivers and HCPs. PMID- 30273980 TI - Children and Adults Selectively Attribute Shared Cultural Knowledge to Speakers of the Same Language. AB - Children's and adults' attributions of shared knowledge of and shared preference for songs were investigated across two prominent social categories: language and gender. Both attributions indicate similarity among individuals but shared cultural knowledge can be more informative about common social history than shared preference, as it is mainly transferred through social interactions within cultures, while preferences can have various sources. Both 5- to 6-year-old children (N = 60) and adults (N = 160) generalized knowledge of songs across individuals who speak the same-language rather than same-gender individuals. In contrast, preference for songs was not systematically generalized across either category. Thus, individuals selectively infer shared cultural knowledge among same-language speakers, suggesting an early emerging link between shared knowledge and cultural boundaries. PMID- 30273979 TI - Characterisation of impaired wound healing in a preclinical model of induced diabetes using wide-field imaging and conventional immunohistochemistry assays. AB - Major complications of diabetes lead to inflammation and oxidative stress, delayed wound healing, and persistent ulcers. The high morbidity, mortality rate, and associated costs of management suggest a need for non-invasive methods that will enable the early detection of at-risk tissue. We have compared the wound healing process that occurs in streptozotocin (STZ)-treated diabetic rats with non-diabetic controls using contrast changes in colour photography (ie, Weber Contrast) and the non-invasive optical method Spatial Frequency Domain Imaging (SFDI). This technology can be used to quantify the structural and metabolic properties of in-vivo tissue by measuring oxyhaemoglobin concentration (HbO2 ), deoxyhaemoglobin concentration (Hb), and oxygen saturation (StO2 ) within the visible boundaries of each wound. We also evaluated the changes in inducible nitric oxide synthase (iNOS) in the dermis using immunohistochemistry. Contrast changes in colour photographs showed that diabetic rats healed at a slower rate in comparison with non-diabetic control, with the most significant change occurring at 7 days after the punch biopsy. We observed lower HbO2 , StO2 , and elevated Hb concentrations in the diabetic wounds. The iNOS level was higher in the dermis of the diabetic rats compared with the non-diabetic rats. Our results showed that, in diabetes, there is higher level of iNOS that can lead to an observed reduction in HbO2 levels. iNOS is linked to increased inflammation, leading to prolonged wound healing. Our results suggest that SFDI has potential as a non-invasive assessment of markers of wound-healing impairment. PMID- 30273981 TI - Associations Between Perceived Material Deprivation, Parents' Discipline Practices, and Children's Behavior Problems: An International Perspective. AB - This study investigated the association between perceived material deprivation, children's behavior problems, and parents' disciplinary practices. The sample included 1,418 8- to 12-year-old children and their parents in China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States. Multilevel mixed- and fixed-effects regression models found that, even when income remained stable, perceived material deprivation was associated with children's externalizing behavior problems and parents' psychological aggression. Parents' disciplinary practices mediated a small share of the association between perceived material deprivation and children's behavior problems. There were no differences in these associations between mothers and fathers or between high- and low- and middle-income countries. These results suggest that material deprivation likely influences children's outcomes at any income level. PMID- 30273982 TI - High mobility group box-1 induces pro-inflammatory signaling in human nucleus pulposus cells via toll-like receptor 4-dependent pathway. AB - Intervertebral disc (IVD) degeneration (DD) is associated with low back pain, the leading cause of disability worldwide. Damage-associated molecular patterns (DAMPs) that contribute to inflammation and trigger DD have not been well characterized. Extracellular high mobility group box-1 (HMGB1) protein has been implicated as a potent DAMP and pro-inflammatory stimulus in the immune system. In this study, we show that HMGB1 and IL-6 levels increase in patients with advanced DD in comparison to early DD. This study further tested the hypothesis that HMGB1 promotes inflammatory signaling driving DD in human nucleus pulposus (NP) cells and tissue. Immunofluorescence and western blot analysis confirmed the expression of HMGB1 and its extracellular release by NP cells under cell stress. Gene expression and protein quantification indicate that HMGB1 stimulates the expression IL-6 and MMP-1 in a dose-dependent manner. The contributions of toll like receptor (TLR) -2, -4 and receptor for advanced glycation end products (RAGE) as receptors mediating HMGB1 signaling was examined using small molecule inhibitors. Inhibition of TLR-4 signaling, with TAK-242, completely abrogated HMGB1 induced IL-6 and MMP-1 expression, whereas inhibition of TLR-2, with O vanillin, or RAGE, with FPS-ZM1, had mild inhibitory effects. HMGB1 stimulation activated NF-KB signaling while TAK-242 co-treatment abrogated it. Lastly, effects of HMGB1 on matrix deposition was evaluated in a 3D culture system of human NP cells. These results implicate HMGB1 as a potent DAMP that promotes inflammation in NP cells and degradation of NP tissues. TLR4-HMGB1 axis is a potential major pathway to alleviate disc inflammation and mitigate DD. (c) 2018 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res. PMID- 30273983 TI - LRH1 as a promising prognostic biomarker and predictor of metastasis in patients with non-small cell lung cancer. AB - BACKGROUND: LRH1, which promotes the malignant transformation of carcinoma, has recently been documented in several types of malignancies. However, LRH1 has not been assessed as a potential clinical biomarker in any cancer. METHODS: LRH1 expression was tested in fresh-frozen tissue samples with quantitative real-time PCR and Western blot analysis. Surgically resected tumor tissues were collected from 156 non-small cell lung cancer (NSCLC) patients: 75 with adenocarcinoma and 81 with squamous cell carcinoma. Subsequently, the immunohistochemical expression of LRH1 was examined, and its clinical significance was evaluated. RESULTS: LRH1 overexpression was observed in NSCLC carcinoma tissues compared to adjacent normal lung tissues. LRH1 expression was correlated with poorer differentiation (P = 0.023), pathological tumor classification (P < 0.001), advanced pathological tumor node metastasis stage (P = 0.017), adenocarcinoma subtype (P = 0.031), and positive lymph node metastasis (P < 0.001). Multivariate analysis demonstrated that LRH1 expression status was an independent prognostic factor for overall (hazard ratio 1.372, 95% confidence interval 1.225-1.617; P = 0.003) and disease free survival (hazard ratio 1.497, 95% confidence interval 1.059-2.115; P = 0.011) in patients who suffered from resectable NSCLC. CONCLUSION: The results of our study indicate that LRH1 predicts NSCLC progression, metastasis, and a dismal prognosis, emphasizing its promising role as a novel target in NSCLC therapies. PMID- 30273984 TI - Pressure injury prevention and management practices among nurses: A realist case study. AB - The prevention and management of a pressure injury is a nurse-sensitive quality indicator in hospitals. Prevention and management of pressure injury practices have been found to be suboptimal despite the availability of interventions. Currently, there is a poor understanding of the mechanisms behind these interventions. The aim of the study was to explain a realistic portrayal of nurses' current practices to prevent and manage pressure injuries in one public hospital in Singapore. A realistic case study design was adopted. Twenty-four nurses were recruited. Audio-recorded interviews were transcribed verbatim to facilitate thematic analysis. Prevention and management was generally facilitated through the timely escalation of care, effective communication, support from the wound nurses, and bridging of the knowledge-practice gap. However, factors such as nurses' intrinsic characteristics and organisational support may affect the outcomes of these facilitators. Overall, nurses strive to achieve patient safety, where pressure injuries are prevented to the best of their abilities. This study provides causal links between contextual factors, mechanisms of the prevention and management, and the outcomes achieved. Further refinement and testing of the specific mechanisms are needed and will contribute to a better understanding of how nurses prevent and manage pressure injuries. PMID- 30273986 TI - Symptomatic venous thromboembolism after non-operatively treated foot or ankle injury. AB - The purpose was to assess the incidence and risk factors associated with symptomatic venous thromboembolism in patients undergoing below knee immobilization for non-operative foot or ankle injury. We included all foot and ankle patients between January 2005 and May 2016 who underwent non-operative management using below knee immobilization with cast, splint, brace, and/or boot. The primary outcome was the development of a venous thromboembolism within 90 days of immobilization initiation. Of 6,088 patients, twenty-three (0.38%) developed a venous thromboembolism. Risk factors for venous thromboembolism were age>50 years, unremovable immobilization, Achilles tendon rupture, Modified Charlson Comorbidity Index>2, patients on chemoprophylaxis, varicose veins, history of venous thromboembolism, known hypercoagulability disorder, and rheumatoid arthritis. Routine thromboprophylaxis after below-knee immobilization for non-operative foot or ankle injury may be beneficial in these specific subpopulations. These data can facilitate more substantive shared decision-making between providers and patients with respect to use of thromboprophylaxis. (c) 2018 Orthopaedic Research Society.

AB - INTRODUCTION: Haemophilia is a recessive X-linked inherited bleeding disorder, whose typical symptom is spontaneous intra-articular haemorrhage leading to joint damage, which can be quantified by the Haemophilia Joint Health Score (HJHS). Arthropathy and other characteristics of haemophilic patients may reduce bone mineral density (BMD), increasing the risk for fragility fractures, which also may occur due to bone quality impairment. AIM: To evaluate bone quantity by BMD and bone quality by Trabecular Bone Score (TBS), bone strain (BS) and hip structural analysis (HSA) in a haemophilic population, and to relate these parameters to general and specific risk factors for osteoporosis and to HJHS. METHODS: Seventy haemophilic patients >=18 years were enrolled. Densitometric derived lumbar spine and femoral BMD with TBS, BS and HSA were performed. Data regarding risk factors for osteoporosis, presence of arthroprosthesis or arthrodesis were collected, and HJHS was calculated. A Z-score <=-2.0 defined a low bone mass. RESULTS: Overall, a reduced bone mass was present in 52 patients at the femur and in 38 at the lumbar spine. Lumbar spine BMD, TBS and BS did not correlate with HJHS. HSA bone geometric parameters correlated negatively with HJHS. BMD and HSA correlated with some risk factors for osteoporosis, namely HIV and its therapy, hepatitis C and smoking. CONCLUSIONS: Haemophilic patients showed a reduced BMD at lumbar spine and/or femur. Femoral bone density and geometry correlated with HJHS. The microarchitecture of the trabecular vertebral bone seemed to be not influenced by the haemophilic joint damage. PMID- 30273988 TI - The mediating role of coping between self-reported health complaints and functional limitations, self-assessed work ability and work status of long-term sick-listed cancer survivors. AB - Our purpose was to investigate the possible mediating role of active coping and passive coping between self-reported health complaints and functional limitations, as assessed by an insurance physician (IP), self-assessed work ability and work status in cancer survivors on long-term sick leave. Validated questionnaires were used for self-reported health complaints, work ability and work status. The functional limitations of the respondents were transformed into scales for mental and physical limitations and limitations in working hours. Using LISREL, we constructed a model with coping in a mediating role. Active coping mediated between fewer self-reported physical limitations, more depressive symptoms, better cognitive functioning and more fatigue on the one hand, and more physical limitations and limitations in working hours on the other hand. Passive coping played no mediating role and was associated with more self-reported depressive symptoms only. More functional limitations were associated with lower self-assessed work ability of cancer survivors, and with not being at work, whereas higher self-assessed work ability was associated with being at work. Regarding the role of active and passive coping strategies in cancer survivors on long-term sick leave, more longitudinal research is needed to confirm causality. PMID- 30273985 TI - Effect of electroconvulsive therapy on brain-derived neurotrophic factor levels in patients with major depressive disorder. AB - OBJECTIVES: Brain-derived neurotrophic factor (BDNF) has been associated with depression and its treatment response. The aim of the present study was to explore the effect of electroconvulsive therapy (ECT) on serum and plasma BDNF levels and change of Montgomery-Asberg Depression Rating Scale (MADRS) and their associations in patients with major depressive disorder (MDD). METHODS: The study included thirty patients suffering from MDD. Their serum and plasma BDNF levels were examined before ECT (baseline) and after the first, fifth, and last ECT session. The severity of the depression and the response to ECT were measured with MADRS. RESULTS: Electroconvulsive therapy caused no significant changes in serum BDNF levels. Plasma BDNF levels decreased during the fifth ECT session between the baseline and the 2-hr samples (p = 0.019). No associations were found between serum or plasma BDNF levels and remission. The correlations between plasma and serum BDNF levels in each measurement varied between 0.187 and 0.636. CONCLUSIONS: Neither serum nor plasma BDNF levels were systematically associated with the clinical remission. However, the plasma BDNF levels somewhat varied during the ECT series. Therefore, the predictive value of BDNF for effects of ECT appears to be at least modest.

AB - The N-iodosuccinimide-mediated spirocyclization of tryptamine-derived isocyanides to generate spiroindolenines is reported. The products contain both an imine and an imidoyl iodide as flexible handles for follow-up chemistry. Nucleophilic addition typically occurs chemoselectively on the imine moiety with complete diastereoselectivity, providing opportunities for the construction of complex molecular frameworks. The synthetic potential of the method was showcased in the formal total synthesis of (+/-)-aspidofractinine. PMID- 30273990 TI - Changes in and modifiable patient- and family caregiver-related factors associated with cancer patients' high self-perceived burden to others at the end of life: A longitudinal study. AB - This prospective, longitudinal study explored changes in and modifiable factors associated with high self-perceived burden to others (SPB) among a convenience sample of 276 dyads of terminally ill Taiwanese cancer patients and their family caregivers over patients' last year of life. High SPB was evaluated by scores >=20 on the Self-Perceived Burden Scale. Modifiable factors of high SPB included factors related to both patients (i.e., symptom distress, functional dependence and coping capacity) and caregivers (i.e., caregiving burden, depressive symptoms and quality of life [QOL]). Modifiable factors of high SPB were identified by multivariate logistic regression modelling with the generalised estimating equation while controlling for demographic factors. We found that patients tended to experience high SPB if they had more symptom distress. In contrast, the likelihood of high SPB was significantly lower if patients had greater coping capacity and their caregivers reported better QOL. High SPB was not associated with patients' functional dependence, caregivers' caregiving burden and depressive-symptom level while providing end-of-life (EOL) care, and time proximity to death. Healthcare professionals may alleviate terminally ill cancer patients' high SPB at EOL through palliative care that adequately manages patients' physical symptom distress, enhances patients' coping capacity and improves family caregivers' QOL.

AB - We present a blue mussel exposure system where the fate of microplastics (polystyrene beads) is tracked during exposure and depuration phases. This enabled the establishment of a complete mass balance. Quantification of beads in mussels was done with a novel enzymatic digestion protocol. We found a similar relative distribution of beads for 2 environmentally realistic concentrations (5 and 100 beads L-1 ) and no substantial egestion of particles within 2 h of depuration.

PMID- 30273992 TI - Comparative tissue distribution and depuration characteristics of copper nanoparticles and soluble copper in rainbow trout (Oncorhynchus mykiss). AB - The continuously growing number of products containing nanoparticles (NPs) makes their presence in the environment inevitable, and given the well-known toxicity of dissolved metals, concerns regarding the toxicity of metal-based NPs have been raised. Whether metal-based NPs present similar or different toxicological effects compared with metal salts is an emerging field. In the present study, rainbow trout were intraperitoneally injected with CuSO4 or copper NPs (CuNPs) to investigate tissue distribution and depuration characteristics. Fish injected with Cu showed an initial accumulation of Cu in the liver, kidney, gills, intestine, and carcass. The Cu concentration in the liver of CuNP-injected fish increased over time. It appears as though CuNPs accumulated in the liver at a greater rate than they were excreted. In livers of fish injected with CuSO4 , the Cu concentration appeared to increase and reach an equilibrium, suggesting that copper was accumulated and excreted at the same rate. The possibility that CuNPs can accumulate at a higher rate than it is excreted in the liver warrants further investigation. The present study demonstrates the possibility of dietary uptake of CuNPs because elevated Cu concentrations were observed in carcass, gills, kidney, and intestine of fish gavaged with CuNPs. In conclusion, the results suggest that dietary CuNPs are taken up by the gut and preferentially accumulate in the liver. Environ Toxicol Chem 2018;9999:1-10. (c) 2018 SETAC. PMID- 30273993 TI - Radiostereometric analysis of the initial stability of internally fixed femoral neck fractures under differential loading. AB - We examined the feasibility of radiostereometric analysis (RSA) in the assessment of the initial stability of internally fixed femoral neck fractures. The study included 16 patients (mean age 73 years). During surgery, multiple RSA-beads were inserted on both sides of the fracture. Radiographs for RSA were taken in the supine position within the first 3 days and 6, 12, 24, and 52 weeks after surgery. To detect any inducible motion at the fracture-site, radiographs for RSA were taken with the patient resting or applying a load through the fracture. Fracture loading was achieved by the patient pressing the ipsilateral foot as much as tolerated on a force plate while providing a counterforce through both hands. Micromotion exceeding the precision values of RSA (>=0.3 mm for the translation vector and/or >=1.2 degrees for the rotation vector) was considered significant. Permanent three-dimensional fracture-site displacement was also recorded. Voluntary loading induced fracture-site micromotion, which exhibited a dichotomous distribution. In patients with uncomplicated fracture union, inducible micromotion was detectable only at baseline-if at all. Conversely, fractures that developed a nonunion were characterized by the continuation of inducible micromotion beyond baseline. Permanent fracture-site displacement was, on average, nearly an order of magnitude greater than the inducible micromotion. Fracture unions were characterized by the cessation of permanent fracture-site displacement by 12 weeks. Nonunions presented as outliers in permanent fracture site displacement. Large-scale studies are warranted to evaluate whether the detection of inducible micromotion beyond baseline could serve as an indicator of insufficient fixation stability. (c) 2018 The Authors.

PMID- 30273994 TI - Group B streptococcus colonisation and associated risk factors among pregnant women: A hospital-based study and implications for primary care. AB - BACKGROUND: Group B streptococcus (GBS), which asymptomatically colonises the vaginal and rectal areas of women, is a leading cause of neonatal mortality and morbidity. This study aimed to determine the prevalence and factors associated with GBS colonisation among pregnant women in Shenzhen, China. METHODS: A hospital-based cross-sectional survey was conducted, using a multistage sampling method. Pregnant women at >=28 weeks' gestation completed a questionnaire and vaginal swabs were obtained for GBS analysis. Data were analysed by chi-squared tests and logistic regression models. RESULTS: The colonisation rate of GBS among pregnant women was 4.9%. The influencing factors associated with GBS colonisation included body mass index before pregnancy (odds ratio [OR] = 3.79, 95% CI 1.28 11.26), gestational age (OR = 5.81, 95% CI 1.20-28.15), induced abortion (OR = 0.63, 95% CI 0.40-0.98) and lotion use before pregnancy (OR = 1.59, 95% CI 1.04 2.44). CONCLUSIONS: Our findings suggest that obesity, gestational age, induced abortion and lotion use were significantly associated with GBS colonisation. Further longitudinal research is needed to establish the causal relationship and its biological mechanisms. PMID- 30273995 TI - Failure loads of all-ceramic cantilever fixed dental prostheses on post-restored abutment teeth: influence of the post presence and post position. AB - The influence of a fiber post-restored abutment tooth on the load capability of a three-unit zirconia framework cantilever fixed dental prosthesis (cFDP) was evaluated after simulated clinical function. Human lower sound premolars (n = 64) were distributed, in equal numbers, to four experimental groups: two vital abutment teeth (group I; control); mesial abutment tooth post-restored (group II); distal abutment tooth post-restored (group III); and mesial and distal abutment teeth post-restored (group IV). All specimens received an adhesively luted three-unit cFDP of veneered zirconia. Simulated clinical function was performed by two subsequent sequences of thermal-cycling (2 * 3,000 cycles) and mechanical loading (1.2 * 106 load cycles from 0 to 50 N) (TCML). Four specimens failed during TCML (one in each of groups I and IV and two in group II). The maximum load capability ranged from 365 to 538 N and was not significantly different between groups. Specimens with post-restored abutments failed mainly because of abutment tooth fracture of the distal abutment. The presence or position of post-restored abutment teeth has no significant impact on load capability of all-ceramic three-unit cFDPs. The risk of tooth fracture of the distal abutment teeth of a cFDP was significantly increased when one abutment tooth, irrespective of its position, was post-and-core restored. PMID- 30273996 TI - Monte Carlo and 60 Co-based kilovoltage x-ray dosimetry methods. AB - PURPOSE: This work seeks to investigate new methods to determine the absorbed dose to water from kilovoltage x rays. Current methods are based on measurements in air and rely on correction factors in order to account for differences between the photon spectrum in air and at depth in phantom, between the photon spectra of the calibration beam and the beam of interest, or in the radiation absorption properties of air and water. This work aims to determine the absorbed dose to water in the NIST-matched x-ray beams at the University of Wisconsin Accredited Dosimetry Calibration Laboratory (UWADCL). This will facilitate the use of detectors in terms of dose to water, which will allow for a simpler determination of dose to water in clinical kilovoltage x-ray beams. MATERIALS AND METHODS: A model of the moderately filtered x-ray beams at the UWADCL was created using the BEAMnrc user code of the EGSnrc Monte Carlo code system. This model was validated against measurements and the dose to water per unit air kerma was calculated in a custom built water tank. Using this value and the highly precise measurement of the air kerma made by the UWADCL, the dose to water was determined in the water tank for the x-ray beams of interest. The dose to water was also determined using the formalism defined in the report of AAPM Task Group 61 and using a method that makes use of a RESULTS: The BEAMnrc models used in this work produced simulations of transverse and depth dose profiles that agreed with measurements with a 2%/2 mm criteria gamma test. The dose to water as determined from the different methods used here agreed within 3.5% at the surface of the water tank and agreed within 1.8% at a depth of 2 cm in phantom. The dose-to-water values all agreed within the associated uncertainties of the methods used in this work. Both the Monte Carlo-based method and the CONCLUSION: Two new dose determination methods were used to determine the dose to water in the NIST-matched x-ray beams at the UWADCL and they showed good agreement with previously established techniques. Due to the improved Monte Carlo calculation techniques used in this work, both of the methods have lower uncertainties compared to TG-61. The methods presented in this work compare favorably with calorimetry-based standards established at other institutions. PMID- 30273997 TI - Circulating markers of collagen types I, III, and IV in patients with dilated cardiomyopathy: relationships with myocardial collagen expression. AB - AIMS: Collagen-derived peptides such as collagen I C-terminal telopeptide (CITP) and procollagen III N-terminal propeptide (PIIINP) have been conventionally used as markers of cardiac fibrosis. Collagen IV 7S domain (P4NP 7S) has been recently reported to be correlated with haemodynamics in patients with acute heart failure. We investigated whether these markers reflect cardiac remodelling and myocardial collagen expression. METHODS AND RESULTS: In 80 patients with dilated cardiomyopathy, relationships of CITP, PIIINP, and P4NP 7S to clinical and echocardiographic variables were analysed. CITP and PIIINP were inversely correlated with estimated glomerular filtration rate (r = -0.41, P < 0.001 and r = -0.32, P = 0.004, respectively); P4NP 7S was positively correlated with B-type natriuretic peptide (r = 0.32, P = 0.003) and gamma-glutamyltransferase (r = 0.38, P < 0.001). These correlations were significant even after adjustment by potential confounders, whereas all three collagen markers were not independently correlated with ejection fraction nor with left ventricular (LV) diastolic diameter. In 33 patients undergoing endomyocardial biopsy, myocardial collagen I and III mRNA expressions were correlated with LV end-diastolic volume index (r = 0.42, P = 0.02 and r = 0.54, P = 0.002, respectively), whereas myocardial collagen IV mRNA expression was not correlated with LV end-diastolic volume index nor with ejection fraction. Each collagen-derived peptide was not significantly correlated with the myocardial expression of their corresponding collagen mRNA. CONCLUSIONS: Our study shows that CITP, PIIINP, and P4NP 7S do not reflect myocardial collagen mRNA expression but presumably reflect extra-cardiac organ injury in heart failure. PMID- 30273998 TI - Preimplantation factor modulates acute inflammatory responses of equine endometrium. AB - Persistent mating-induced endometritis (PMIE) is a significant cause of mare infertility hence its treatment would advance the management of susceptible mares. Preimplantation factor (PIF) is secreted by viable embryos, including human, mouse and cattle, and is essential for maternal immune-tolerance without immune-suppression by modulating inflammation. This preliminary study aimed to test whether PIF exerts inflammatory-modulating properties upon equine endometrium challenged with Escherichia coli-derived lipopolysaccharide (LPS) using endometrial explant culture. Follicular (n = 3), luteal (n = 4), anoestrous (n = 4) and transitional (n = 4) stage endometrial explants were established and cultured in triplicate in either serum-free medium alone (control) or medium with; 50 or 100 nmol/L synthetic PIF (sPIF); 3 MUg/mL LPS; LPS and 50 or 100 nmol/L sPIF; or scrambled PIF (PIFscr; same amino acid composition arranged in a different order). Media samples were collected at 24 and 72 h, representing acute and chronic inflammatory response. Radioimmunoassay determined Prostaglandin F2alpha (PGF2alpha ) as an inflammatory marker. The only significant observation was the abrogation of PGF2alpha response to LPS challenge by 100 nmol/L PIF for follicular stage tissue, 24 h after treatment. Further studies are therefore, warranted to realise PIF potential in managing PMIE. PMID- 30273999 TI - Detection of Methylated SEPT9 in Korean Colorectal Cancer Patients: Comparison with Previous Studies. AB - BACKGROUND: This study aimed to investigate the detection of methylated Septin 9 (mSEPT9) in Korean patients with colorectal cancer (CRC) and compare the results with those of previous studies. METHODS: A total of 127 plasma samples (111 patients with untreated CRC, 5 patients with adenomas, and 11 CRC patients treated with concurrent chemoradiotherapy before surgery) were collected. mSEPT9 was measured qualitatively with the Abbott RealTime ms9 Colorectal Cancer Assay. RESULTS: mSEPT9 was detected in 44 of 111 (39.6%) cases of untreated CRC but was not detected in the adenoma cases. The difference in the sensitivity of mSEPT9 among patients with adenomas and those with each stage of untreated CRC was statistically significant (Dukes' staging, p = 0.002 and TNM staging, p = 0.008). The sensitivity of mSEPT9 for each of the stages (I - IV) of untreated CRC patients were 20.7%, 54.1%, 36.6%, and 75.0%, respectively. The positive mSEPT9 results in untreated CRC patients reverted to negative in 19 of 21 patients (90.5%) after treatment. CONCLUSIONS: Compared to previous studies, the overall sensitivity of mSEPT9 was lower, but similar patterns were found in the sensitivities for each stage. Additionally, mSEPT9 appeared to have potential as a monitoring tool for CRC. PMID- 30274000 TI - A Simple and Accurate Measurement Procedure for Serum Chloride by Ion Chromatography and Bias Evaluation of Six Ion Selective Electrode Measurements in China. AB - BACKGROUND: Chloride is the main anion in human body. A simple and accurate method for serum chloride measurement was developed using ion chromatography (IC) in China. METHODS: In the measurement, serum samples were diluted 500 times with water, filtered and injected into ion chromatography column. A mixed eluent (2 mmol/L CO32- + 12 mmol/L OH-) was used and peak area signal was collected. Five calibrators made from Standard Reference Material (SRM) 919b were used in the bracketing method. The IC method was applied as the comparative method and six ion selective electrode (ISE) measurement systems were evaluated using 60 individual patient serums. RESULTS: The IC method was proven to be accurate. The precision was 0.18% - 0.30%, the recovery was 99.66% - 100.60%, the bias was 0.19% to -0.06%, and the related expanded uncertainty was 0.775% (k = 2). The precisions of the ISE systems were smaller than the 0.9% tolerable CV except for the Beckman DXC (0.91% - 1.16%). In comparison, the results of linear regression analysis showed that the correlation coefficients were 0.9876 to 0.9979. For all systems, the range of mean biases was -5.96 - 1.48 mmol/L (-5.57% - 1.36%); the expected biases at the medical decision levels were -4.97% - 0.84% at 90 mmol/L and -6.02% - 1.76% at 120 mmol/L. All biases of the Beckman AU met the requirement of within +/- 1.5%. CONCLUSIONS: The IC measurement method is proven to be of high precision and trueness, and the quality of routine ISE measurement of serum chloride still needs significant improvement. The establishment of the IC method can improve the measurement quality and promote its standardization process in China. PMID- 30274001 TI - Serum Soluble ST2 as a Novel Inflammatory Marker in Acute Ischemic Stroke. AB - BACKGROUND: Soluble ST2 (sST2) receptor is secreted and detectable in human serum, which acts as a decoy receptor for interleukin (IL)-33 to prevent IL-33 mediated Th2 immune responses. Recently, elevated serum sST2 has been found to be a novel biomarker in cardiovascular diseases such as heart failure and atherosclerosis. Here, we studied the role of sST2 in acute ischemic stroke (AIS) and its relationship with several inflammatory markers. METHODS: The study included 112 patients with first-ever acute ischemic stroke, who were admitted within 48 hours after stroke onset. The serum levels of sST2 and IL-33 were measured with ELISA and the severity of AIS patients was evaluated based on the National Institutes of Health Stroke Scale (NIHSS) score. The cerebral infarct volume was calculated according to the Pullicino formula based on the cranial CT scan or MRI. High-sensitivity C-reactive protein (hs-CRP) and serum amyloid A protein (SAA) were measured using the latex-enhanced immunoturbidimetric assay. RESULTS: The serum sST2 level was significantly increased in patients with AIS compared to the control patients without AIS. In addition, the concentration of serum sST2 increased with the infarct volume and the severity of AIS evaluated based on the NIHSS score. Furthermore, the sST2 level correlated positively with the inflammatory marker hs-CRP. CONCLUSIONS: Our study suggests that sST2 may be used as a novel diagnostic and predicting inflammatory marker in AIS. PMID- 30274002 TI - Expression of Long Non-Coding RNA PRAL as a Potential Biomarker for Diagnosis in Non-Small-Cell Lung Cancer Patients is Associated with the Inhibition of Cell Proliferation and Metastasis. AB - BACKGROUND: Accumulating evidence reveals that long non-coding RNAs (lncRNAs) play a crucial role in pathogenesis of non-small-cell lung cancer (NSCLC), providing a new concept to exploit novel biomarkers for diagnosis, prognosis or therapeutic target of NSCLC. The intention of this study was to examine the viability of lncRNA PRAL as a biomarker for NSCLC and explore its biological function in NSCLC cell lines. METHODS: PRAL transcription levels were evaluated using Q-PCR. Receiver operating characteristic (ROC) curve analyses were used to evaluate the diagnostic value for NSCLC patients. Kaplan-Meier analysis and log rank test were performed to assess the correlation between PRAL expression and the clinical outcomes on overall survival (OS) and progression-free survival (PFS). RESULTS: PRAL expression levels were prominently decreased in a majority of the NSCLC tumor tissues compared with corresponding adjacent normal tissues (p < 0.0001) and healthy tissues (p < 0.0001). Receiver operating characteristic (ROC) curve analyses indicated strong separation between the NSCLC tissues and the control group, with an AUC of 0.8546 (95% CI: 0.7993 to 0.9098; p < 0.0001) for PRAL. Using the Chi-square test showed an obvious negative correlation between down-regulated PRAL levels and advanced TNM stage (chi2 = 8.826, p = 0.003). High PRAL levels had a longer median OS and median PFS (median OS, 42 months vs. 33.5 months, p = 0.0122; median PFS, 30 months vs. 24.5 months, p = 0.0317). Univariate and multivariate analysis of clinical pathological factors were also performed. In addition, over-expression of PRAL blocked proliferation,migration, and invasion in NSCLC cell lines. CONCLUSIONS: Taking these results together, PRAL expression level could be a potential biomarker for diagnosis in NSCLC patients. PMID- 30274003 TI - Clinical Value of Human Papillomavirus E6/E7 mRNA Detection in Screening for Cervical Cancer in Women Positive for Human Papillomavirus DNA or. AB - BACKGROUND: The detection of human papillomavirus (HPV) E6/E7 mRNA indicates a risk of further deterioration in cervical lesions. We explored the clinical value of HPV E6/E7 mRNA detection in cervical cancer screening in women positive for HPV or with abnormal thin-prep cytology test (TCT) results in the Xinjiang region of China. METHODS: A total of 6,800 women were screened in our hospital for cervical cancer by both TCT and HPV DNA testing from August 2013 to June 2015. Of these, 197 had abnormal cytological or HPV test results and subsequently underwent HPV E6/E7 mRNA detection and histopathological examination, while 101 underwent an HPV DNA typing test. Using pathological results as the gold standard, we compared the accuracies of HPV E6/E7 mRNA detection or HPV DNA type testing alone, in parallel, and in series for diagnosing high-grade cervical lesions. RESULTS: Pathological examination revealed 80 cases of chronic cervicitis, 16 cases of cervical intraepithelial neoplasia (CIN)-I, 50 cases of CIN-II-III, and 51 cases of cervical cancer. The area under the receiver operating characteristic (ROC) curve (AUC) for diagnosing high-grade cervical lesions by HPV E6/E7 mRNA detection was 74.95% (sensitivity, 85.15%; specificity, 66.67%; Youden index, 0.139; positive predictive value, 72.9%; negative predictive value, 81.0%; positive likelihood ratio, 2.555; negative likelihood ratio, 0.222; and post-test probability, 72.9%). CONCLUSIONS: HPV E6/E7 mRNA detection is superior to HPV DNA type testing for diagnosing high-grade cervical lesions. PMID- 30274004 TI - Thrombin Generation Testing in Patients with Myelofibrosis. AB - BACKGROUND: Primary myelofibrosis (PMF) is a chronic clonal myeloid disorder. Together with essential thrombocythemia (ET) and polycythemia vera (PV), it belongs to a group of Philadelphia chromosome-negative myeloproliferative neoplasms. Thrombotic events are serious complications negatively influencing the quality and length of these patients' lives. The confirmed risk factors for venous thromboembolism are age over 60 years, a positive history of thromboembolism, presence of common cardiovascular risks, JAK2 V617F mutation and, according to some authors, leukocytosis. Various opinions on the role of thrombocythemia have been published. The present study was undertaken to evaluate the benefit of thrombin generation test and its potential use in predicting the risk of thrombosis in MF patients. METHODS: The analysis included plasma samples obtained from 36 patients diagnosed with MF in our center from 2004 to 2016 (JAK2 V617-positive 53%; CALR-positive 31%; MPL-positive 14%; triple negative 2%) and a control group comprising 20 healthy volunteer blood donors. Thrombin generation was measured in platelet-rich plasma using the TECHNOTHROMBIN(r) TGA kit (Technoclone, Austria) and the fully automated system Ceveron(r) Alpha (Technoclone). The results were correlated with clinical and laboratory parameters of the patients. RESULTS: There were differences in thrombin generation as expressed by endogenous thrombin potential (ETP) between patients and healthy controls, with ETP being lower in the patient group (p = 0.0003). Analysis confirmed a significant correlation between thrombin generation and platelet counts, with higher thrombin generation in patients with thrombocythemia > 400 x 109/L (p = 0.04). ETP values were consistently higher in earlier disease stages and lower in CALR-mutated myelofibrosis. CONCLUSIONS: In MF patients, thrombin generation is mainly influenced by platelet counts and, to a lesser extent, by mutation status, activity, and progression of the disease. Thrombin generation test results have confirmed that thrombocythemia is a potential risk factor for thrombotic complications. PMID- 30274005 TI - The Association between Infertility and Helicobacter pylori Infection: a Meta Analysis of Case-control Studies. AB - BACKGROUND: Helicobacter pylori (H. pylori) is increasingly associated with extra digestive diseases. Infertility is a common condition, with an incidence of 10 to 15% of couples. Studies examining the association of H. pylori infection and infertility have reported conflicting results. This meta-analysis aimed to investigate the association between H. pylori infection and infertility. METHODS: Studies of H. pylori infection and infertility were identified in PubMed, EMBASE, the Cochrane Library, and China National Knowledge Infrastructure. We performed a meta-analysis of all case-control studies. RESULTS: Seven studies that analyzed the relationship between H. pylori infection and infertility, with a combined study population of 1,902 patients, were included in the meta-analysis (n = 626 for patients; n = 1,276 for controls). In the infertility group, 344 (54.9%) patients were H. pylori-positive, and 495 (38.8%) were H. pylori-positive in the control group. Our result suggested that H. pylori infection was associated significantly with infertility (OR = 1.45, 95% CI: 1.197 - 2.160; I2 = 36.5%, Z = 3.15, p = 0.002). Begg's and Egger's funnel plot showed no publication bias (p = 0.807). CONCLUSIONS: Our meta-analysis identified a possible association between H. pylori infection and infertility. PMID- 30274006 TI - Neutrophil-to-Lymphocyte Ratio as a Potential Early Marker of Antibiotic Resistance in Patients with Infected Cirrhotic Ascites. AB - BACKGROUND: To evaluate the role of neutrophil-to-lymphocyte ratio (NLR) in identification and management of infected ascites among patients with cirrhosis. METHODS: A total of 439 patients (mean (SD) age: 64.5 (+/- 12.7) years, 63.3% were males) hospitalized with cirrhotic ascites were included in this retrospective study. Data on patient demographics, etiology of cirrhosis, type of ascites (sterile ascites, infected ascites), culture findings treatment response (antibiotic resistance vs. sensitivity) and baseline (Day 0), Day 1 and Day 2 levels for serum C-reactive protein (CRP; mg/L), and NLR were recorded. Receiver operating characteristics (ROC) curve was plotted to determine performance of % change from baseline NLR on Day 1 in identifying treatment response. RESULTS: In patients with infected ascites, antibiotic resistant patients had significantly higher Day 1 (6.9 (1.9 - 74.9) vs. 4.9 (1.1 - 51.1), p = 0.001) and Day 2 (8.0 (2.6 - 75.9) vs. 4.0 (1.1 - 40.3), p = 0.000) levels for NLR as compared with antibiotic sensitive patients, while the two groups had similar baseline (Day 0) NLR values (5.8 (1.1 - 62.3) vs. 5.7 (1.1 - 72.3), p = 0.969). ROC analysis revealed less than 0.93% decrease from baseline NLR on Day 1 (AUC (95% CI): 0.852 (0.799 - 0.895), p < 0.001) to be a potential marker of antibiotic resistance with a sensitivity of 87.72% and specificity of 88.50%. CONCLUSIONS: Our findings indicate percent change from baseline NLR on Day 1 to be a potential early marker of antibiotic resistance in patients with infected cirrhotic ascites. Our findings emphasize the role of determining NLR levels in earlier recognition of treatment failure and thus prompt modification of antibiotic treatment in cirrhotic patients with infected ascites. PMID- 30274007 TI - Effects of Freeze-Thaw Times on Screening Coagulation Tests and Factors VIII and IX Activities in Citrate-Anticoagulated Plasma at -20 degrees C and -80 degrees C. AB - BACKGROUND: Accurate determination of screening coagulation tests and factors VIII and IX activities (FVIII:C and FIX:C) in fresh plasma is very important for diagnosing abnormalities in the intrinsic or extrinsic coagulation pathways and factor deficiencies. If thawed samples cannot be detected for all required items at the same time, or need to be re-tested or re-stored, the thawed samples need to be re-frozen. We planned to perform in-house validation studies on freeze thawed samples for screening coagulation tests, FVIII:C and FIX:C. METHODS: Mean percent changes, numbers of samples with > 10% changes, and difference plots were evaluated to determine clinically relevant differences between results for fresh and freeze-thawed samples. The statistical significance of differences between repeated-measure multiple groups and baseline values were evaluated by repeated measures analysis of variance. RESULTS: The acceptable freeze-thaw cycles for activated partial thromboplastin time, fibrinogen, prothrombin time/international normalized ratio, thrombin time, and FIX:C were three times at -20 degrees C/-80 degrees C, while the acceptable freeze-thaw cycles for FVIII:C were three times at -80 degrees C and once at -20 degrees C. CONCLUSIONS: The freeze-thaw results on stabilities were affected by time and temperature, with lower temperature and fewer times associated with more stable activity. PMID- 30274008 TI - Comparison of Three Routine Methods for the Measurement of Serum Bilirubin in a China Laboratory. AB - BACKGROUND: The reliability of bilirubin measurements is not satisfactory due to the marked variability of methodologies since discovery. METHODS: Imprecision of the three analytical systems (diazo method, vanadate oxidase method, and dry chemistry method) were calculated in accordance with CLSI guidelines EP15-A2. According to Clinical and Laboratory Standards Institute (CLSI) guideline (EP9 A2), 40 analytes were detected to evaluate method performance and comparability among three routine measurements for serum bilirubin in a China laboratory. RESULTS: The within-run precisions and the intermediate imprecision of the three methods all met the CLIA'88 requirement of bilirubin measurement. All three evaluated methods were closely correlated with correlation coefficients ranging from 0.995 to 0.999. The 95% predicted bias confidence intervals between diazo method and vanadate oxidase method for total bilirubin were acceptable. However, for direct bilirubin, the 95% predicted bias confidence intervals was only acceptable at the medium medical decision point. The 95% predicted bias confidence intervals between diazo method and dry medical method for total bilirubin was all acceptable. CONCLUSIONS: All three evaluated routine methods for serum bilirubin in our lab were closely correlated. For measurements of total and direct bilirubin, both dry medical method and vanadate oxidase method had significant differences compared with the diazo method. Further studies are required to reduce the biases among these methods. PMID- 30274009 TI - The Association Between Serum Uric Acid Level and Prognosis in Critically Ill Patients, Uric Acid as a Prognosis Predictor. AB - BACKGROUND: Uric acid is synthesized from xanthine via xanthine oxidase as an end product of purine metabolism. Uric acid is a major non-enzymatic antioxidant in the blood, and it exerts a protective action on vitamin C. There are a limited number of ICU studies related to uric acid, which is a valuable prognostic biomarker. This study aimed to evaluate the utility of uric acid as a biomarker in predicting the outcomes of critically ill patients. METHODS: This prospective, multi-centered cohort study included 128 patients from two different intensive care units who met the study inclusion criteria between May 2017 and October 2017. Study inclusion criteria were first admission to the ICU, age > 18 years, and ICU stay > 24 hours. In each patient, baseline serum uric acid levels were measured after acute interventions, prior to the initiation of the treatment process. RESULTS: When comparing the last uric acid levels of patients, the median last uric acid levels in the non-survival and survival groups were significantly different (p = 0.001). A last uric acid level > 4.5 mg/dL was associated with a 2.638 times higher risk (relative risk) for mortality. According to ROC analysis, a cutoff value of 1.5 for the ratio between the last two uric acid levels had a sensitivity of 0.21 and a specificity of 0.96 for predicting mortality. A 1.5-fold increase in the uric acid level yielded a positive predictive value of 92.6% and a negative predictive value of 65.2% for predicting mortality. The median uric level in the patient subset with ARDS, was significantly higher than those without ARDS (p = 0.001). CONCLUSIONS: Results of this study indicate that a time-dependent increase in uric acid levels can be used as an important biomarker for predicting mortality in critically ill patients; further, uric acid levels should possibly be included in the current mortality risk scoring systems. In addition, elevation of uric acid, a simple, inexpensive, and readily available biomarker, may provide guidance in the diagnostic stage and in predicting clinical outcomes of patients with sepsis or ARDS.

PMID- 30274011 TI - Laboratory Impact of Rapid Molecular Tests used for the Detection of Respiratory Pathogens. AB - BACKGROUND: With outbreaks of new respiratory viruses such as the severe acute respiratory syndrome coronavirus and swine-origin influenza A/H1N1, the nucleic acid-based amplification test was introduced to identify causative agents. Multiplex PCR, which can simultaneously detect various respiratory pathogens, is currently used worldwide. Recently, a new type of multiplexed molecular test using a fully automated workflow system was developed, which was also adapted to our laboratory. In this study, we assessed improvements in laboratory practice brought about by the implementation of the rapid test for the detection of respiratory viruses. METHODS: We investigated the number of routine and rapid tests conducted as well as the change in monthly test frequency of the routine test. We also analyzed the waiting time, turnaround time, and lead time for the routine and rapid tests. The Anyplex II RV16 detection kit (Seegene, Seoul, Korea) and Filmarray Respiratory Panel (BioFire Diagnostics, Inc., Salt Lake City, UT, USA) were used for the routine and rapid tests, respectively. RESULTS: Compared to the routine test, the rapid test significantly (p < 0.01) decreased the mean waiting time (1 hour 46 minutes), turnaround time (1 hour 45 minutes), and lead time (3 hours 32 minutes). After the implementation of the rapid test, the number of routine tests conducted was reduced over the 5-month period, from 13 times a month to 3 times a month. CONCLUSIONS: The implementation of the rapid test for the detection of respiratory viruses improved the diagnostic efficiency of the laboratory and greatly reduced lead time. PMID- 30274012 TI - Relationship Between SLC22A1 and SLC22A4 Gene Polymorphisms and Risk of Type 2 Diabetes in Chinese Han Population. AB - BACKGROUND: This study was to investigate the relationship between SLC22A1 and SLC22A4 gene polymorphisms and genetic susceptibility to type 2 diabetes in Chinese Han population. METHODS: The research group comprised 110 Chinese Han patients with type 2 diabetes, and the control group included 110 healthy volunteers. The polymorphisms of SLC22A1 gene rs628031 and rs2282143 loci and SLC22A4 gene rs2073838 and rs272893 loci were detected in the two groups. RESULTS: Statistically significant differences were identified in the genotype distributions of SLC22A1 gene rs628031 and rs2282143 loci between the two groups (p < 0.05). The A allele frequency of SLC22A1 gene rs628031 locus and the T allele frequency of rs2282143 locus were higher in the research group than in the control group (p < 0.05). The genotype distributions of rs272893 locus showed a significant difference between the two groups (p < 0.05), but not SLC22A4 gene rs2073838 locus (p > 0.05). CONCLUSIONS: The polymorphisms of SLC22A1 gene rs628031 and rs2282143 loci and SLC22A4 gene rs272893 locus of patients with type 2 diabetes indicated a significant difference between the two groups, suggesting that these genetic locus mutations increase the risk of type 2 diabetes in Chinese Han patients. PMID- 30274013 TI - First-Trimester Biochemical Screening For Low Birth Weight: Clinical Effectiveness of Low Pregnancy-Associated Plasma Protein-A and High Thyroid Stimulating Hormone. AB - BACKGROUND: Low birth weight (LBW) can be an important adverse neonatal outcome in terms of morbidity and mortality. The aim of this study is to investigate the screening effectiveness of first-trimester low pregnancy-associated plasma protein A (PAPP-A) and high serum thyroid-stimulating hormone (TSH) and the combination of both markers for predicting LBW. METHODS: We performed a retrospective cohort study of women undergoing first-trimester assessment in our center. We considered low PAPP-A as < 5th percentile for gestational age. High serum TSH was defined as > 2.5 mU/L, according to the American Thyroid Association (ATA) recommendation. Receiver-operating characteristic (ROC) curves were plotted to evaluate screening performance. Multivariate logistic regression was accomplished to calculate adjusted risks to identify the association between both parameters with LBW. RESULTS: Overall, 4,396 women met the inclusion criteria. Of these, 277 (6.3%) delivered a LBW baby. The use of either low PAPP-A or high TSH yielded the highest sensitivity (21.1%) with a specificity of 85.7%. Combining both markers showed an increased association (adjusted OR 9.07 [95% CI 3.34 - 24.6]) at the expense of a significant reduction in sensitivity (7.8%). CONCLUSIONS: First-trimester low PAPP-A is associated with LBW at delivery. Neither of these biomarkers or their combination are acceptable predictors to be clinically useful tools for LBW. PMID- 30274014 TI - Alteration of Serum 25(OH) Vitamin D, Vitamin D Binding Protein, and C-reactive Protein Levels in Acute Leukemia Patients. AB - BACKGROUND: Acute leukemia is a common hematologic malignancy with poorly differentiated leukocytes. Alteration of circulating vitamin D (VD) and its carrier vitamin D binding protein (VDBP) have been reported in certain types of cancers and may play a role in the course of the disease. Understanding of the status of serum VD and VDBP, as well as the acute phase protein C-reactive protein (CRP) levels in pre- and post-treatment of acute leukemia patients, may be helpful in the management of acute leukemia. METHODS: Enzyme linked immunosorbent assay (ELISA), chemiluminescence immunoassay, and immunofluorescent assay were used to analyze the 25(OH) vitamin D (25(OH)D), VDBP, and CRP in the serum of a cohort of leukemia patients. RESULTS: Serum 25(OH)D levels in patients (pre- and post-treatment) were significantly lower than in control subjects. There was no significant difference in 25(OH)D levels between pre- and post treatment. Serum VDBP level was raised in both pre- and post-treatment of acute leukemia patients, with that of pre-treatment being higher. The average serum VDBP was reduced in post-treatment; however, no significant difference was found. Elevated serum CRP levels in both pre- and post-treatment patient groups have been observed but were reduced significantly after treatment. Results also revealed that serum VDBP levels in acute myeloid leukemia patients were significantly higher than in acute lymphoid leukemia patients, while 25(OH)D levels in acute myeloid leukemia were significantly lower than in acute lymphoid leukemia. No significant difference between the serum CRP levels of acute myeloid leukemia and acute lymphoid leukemia was observed. CONCLUSIONS: Serum 25(OH)D, VDBP, and CRP may be used together and could be potential indicators of the disease course of acute leukemia and assist in its management which merits further investigation. PMID- 30274015 TI - NOB1 Gene as a Potential Biomarker in Clinical Outcomes and Prognosis of Patients with Gastric Cancer. AB - BACKGROUND: To investigate relationship of the Nin one binding protein (NOB1) gene with the prognosis of gastric cancer (GC). METHODS: The GC tumor tissues and paired adjacent normal gastric tissues were collected from 65 patients who underwent primary gastric resection surgery in our hospital from January 2009 to July 2011. Data including age, gender, family cancer history, tumor diameter, pathological type, differentiation, clinical stage by tumor node metastasis (TNM) staging, lymphatic metastasis, and distant metastasis were collected. Expression of NOB1 and VEGF was determined using real time PCR. The relationship of NOB1 with clinical outcomes and prognosis of GC patients was analyzed by statistical methods. RESULTS: Both mRNA expression of NOB1 and VEGF was significantly higher in tumor tissues than that of the normal tissues, p < 0.05, and mRNA expression of NOB1 was positively correlated with mRNA expression of VEGF by Pearson's correlation analysis. Significant difference was observed in TNM stage, tumor differentiation, and metastasis between the low and high NOB1 expression groups, p < 0.05, while no significant difference was observed in age, gender, family cancer history, tumor location, and diameter. Univariate analysis showed that TNM stage, tumor differentiation, lymphatic metastasis, distant metastasis and expression of NOB1 and VEGF were all significantly different in survival and dead patients. Logistic analysis showed that NOB1 was an independent risk factor for 5 year mortality of GC patients, as well as lymphatic metastasis and distant metastasis. CONCLUSIONS: NOB1 was correlated with clinical outcomes and prognosis of GC patients and was an independent risk factor for 5-year mortality of GC patients. This study might provide more clinical evidences for NOB1 in GC and give a new target for diagnosis and treatment for GC patients. PMID- 30274016 TI - Performance of LC/MS/MS in Analyzing Multiple Amino Acids and Acylcarnitines in Dried Blood Spot of Very Low Birth Weight, Low Birth Weight, and Normal Weight Neonates. AB - BACKGROUND: Amino acid (AA) and acylcarnitine (AC) are important biomarkers of protein and fatty acid metabolism. Examining their levels in newborns may reveal multiple inherited metabolic diseases. However, they have rarely been assessed in very low birth weight (VLBW) neonates, low birth weight (LBW) neonates and rarely been compared with normal weight (NW) neonates. The aim of the study was to identify the AA and AC profiles in dried blood spot (DBS) specimens of LBW and VLBW neonates, then compare with NW neonates, and make a contribution to the determination of cutoff values of VLBW and LBW neonates. METHODS: Liquid Chromatography tandem mass spectrometry (LC/MS/MS) is an excellent tool for quantitatively detecting AA and AC profiles. This article verified the precision, accuracy, and linearity of the LC/MS/MS method in AA and AC detection, then analyzed AA and AC profiles in DBS of VLBW, LBW and NW neonates, and compared the difference of AA and AC in the three groups. RESULTS: The results showed that the LC/MS/MS method had wide linear range, satisfied precision and reproducibility in detecting AA and AC in DBS specimens; most AA and AC concentrations significantly correlated with birth weight in DBS samples (p < 0.05). CONCLUSIONS: The results suggested that VLBW and LBW neonates have different metabolic or nutritional status with NW neonates and different AA and AC cutoffs should be defined for them to reduce the risk of false-positive cases. PMID- 30274017 TI - The Diagnostic Performance of Urine Flow Cytometer UF1000i for Urinary Tract Infections. AB - BACKGROUND: Urinary tract infections (UTIs) are one of the most common infectious diseases in clinic. Urine flow cytometry is receiving more and more attention due to its rapid forecast of UTIs. METHODS: The Urine Flow Cytometer UF1000i has a series of software programs to quantify bacteria (BACT) and white blood cells (WBC), and describe the scatter diagram of bacteria. The UTIs were predicted based on the cutoff values with the Receiver Operating Characteristic (ROC) curves of BACT and WBC counts. To evaluate the diagnostic performance of UF1000i for UTIs, the sensitivity and specificity of 889 urine samples were determined in comparison to the results of urine culture. Meanwhile the bacterial morphology indication of the UF1000i was evaluated in order to help doctors choose antibiotics. The angle of the scatter cloud with the x-axis was used to classify the infected bacteria as bacilli (< 30 degrees ) or cocci (>= 30 degrees ). RESULTS: The best cutoff value of BACT counts for predicting UTIs was 119 per uL, and the sensitivity and specificity were 95.5% and 88.7%, respectively. While the best cutoff value of WBC counts was 81.5 per uL, and the sensitivity and specificity were 77.6% and 76.7%, respectively. In addition, the best cutoff values for females were 583 BACT per uL and 137.5 WBC per uL. They were much higher than for males (118 BACT per uL and 91 WBC per uL). The coincidence of the bacterial morphology information between the UF1000i software indication and the bacterial actual morphology identified by urine culture was 83% (bacilli) and 68% (cocci), respectively. CONCLUSIONS: Data demonstrated that the performance of BACT counts for UTIs is superior to WBC counts. In addition, the bacterial morphology could preliminarily be predicated by the scatter diagram. Since the urine flow cytometer UF1000i can provide the data of both BACT counts and the scatter diagram, the urine flow cytometry was regarded as a suitable method for screening UTIs. Moreover, it would be better to take gender into consideration when setting the best cutoff value for diagnosis of UTIs in clinic. PMID- 30274019 TI - Serum Human Epididymis Secretory Protein 4 (HE4) is a Potential Prognostic Biomarker in Non-Small Cell Lung Cancer. AB - BACKGROUND: Human epididymis secretory protein 4 (HE4) is a secreted glycosylated protein belonging to the WFDC family, which is an ideal biomarker in ovarian cancer. However, the role of HE4 in lung cancer is still unclear. The study aimed to evaluate serum levels of HE4 as a prognostic biomarker in patients with non small cell lung cancer (NSCLC). METHODS: The subjects consisted of 217 NSCLC patients, which were compared to a control group of 80 patients with benign lung disease and 110 healthy controls. Serum levels of HE4 were measured with electrochemiluminescence assays in a Roche E601 Immunoassay Analyzer. RESULTS: Serum levels of HE4 in NSCLC patients were significantly higher than in benign lung disease and healthy controls (p < 0.001). Using the cutoff value of 78.84 pmol/L, HE4 levels differentiated NSCLC from healthy controls with a sensitivity of 84.2% and a specificity of 78.3%. In the NSCLC subgroups, HE4 was a better discriminator of lung adenocarcinoma (cutoff value, 72.70 pmol/L, area under curve, 0.909; 95% confidence interval, 0.871 - 0.947). Higher serum HE4 levels were significantly correlated with histological type, high TNM stage, and positive lymph node metastasis (p = 0.019, 0.018, 0.002, respectively). Kaplan Meier analysis demonstrated that high HE4 levels predicted poor survival (log rank test: p = 0.007), especially in the adenocarcinoma group (logrank test: p = 0.001). In the Cox model, serum HE4 level was an independent prognostic factor for NSCLC. CONCLUSIONS: Higher serum levels of HE4 predict poor prognosis in NSCLC patients, especially in patients with adenocarcinoma. PMID- 30274018 TI - Decreased Serum Lipid Levels and Ratios Correlate with Low Prevalence of Coronary Heart Disease in Patients with Parkinson's Disease. AB - BACKGROUND: Patients with Parkinson's disease (PD) are at a lower risk of suffering cardiovascular events, but the underlying factors for this decreased risk remain unclear. Serum triglycerides (TG) and total cholesterol (TC), and their expression relative to high-density lipoprotein cholesterol (TG/HDL-C and TC/HDL-C), are independent predictors of cardiovascular events. This study aimed to determine if PD patients have decreased lipid levels and lipid ratios, which may underlie the decreased risk of coronary heart disease (CHD). METHODS: This retrospective study included 92 PD patients (PD group), 450 control subjects with no CHD (OD group), and 450 CHD patients (CHD group). We analyzed serum lipid levels and lipid ratios in each group. RESULTS: There were significant differences in TC (F = 10.459, p < 0.0001), TG (F = 46.856, p < 0.0001), low density lipoprotein cholesterol (LDL-C) (F = 6.910, p = 0.001), high density lipoprotein cholesterol HDL-C (F = 30.694, p < 0.0001), TC/HDL-C (F = 32.675, p < 0.0001), and TG/HDL-C (F = 45.554, p < 0.0001) between all three groups; TC/LDL-C (F = 2.518, p = 0.081) was not significantly different between groups. Compared to the CHD group, PD patients had lower TC (p < 0.0001), TG (p < 0.0001), LDL-C (p = 0.001), TG/HDL-C (p < 0.0001), and TC/HDL-C (p < 0.0001); TC/LDL-C (p = 0.563) and HDL-C (p = 0.196) were not significantly different. TC and LDL-C levels were positively correlated within individual groups (all p < 0.0001). In addition, TG and HDL-C were negatively correlated in the OD and CHD groups (p < 0.0001); no significant negative association was observed in the PD group (p = 0.077). TG/HDL and LDL-C levels were inversely correlated in the CHD group (p < 0.0001) and weakly positively correlated in the PD (p = 0.159) and OD (p = 0.199) groups. CONCLUSIONS: TC/HDL and TG/HDL ratios were significantly lower in PD patients compared to CHD patients, suggesting there is a strong correlation between lipid ratios and incidence of CHD in PD patients. PMID- 30274020 TI - Prognostic Implication of MIF Gene Expression in Childhood Acute Lymphoblastic Leukemia. AB - BACKGROUND: Cytogenetic and molecular genetic markers have been used recently to stratify risk and predict prognosis of different types of cancers. Macrophage migration inhibitory factor (MIF) is a pro-inflammatory cytokine that plays an important role in the pathogenesis of many diseases, such as autoimmune diseases and cancers. We studied MIF gene expression behavior to investigate its prognostic impact in childish patients with acute lymphoblastic leukemia (ALL). METHODS: MIF expression was analyzed using quantitative real-time (QRT) PCR. Patients are classified into two groups, high and low MIF expressers, according to median MIF gene expression. RESULTS: We did not find any significant difference between both groups as regards the clinical and hematological picture. However, high MIF expressers had significantly lower incidence of CR (25.8% vs. 72.4%, p = 0.001), higher incidence of refractory (51.6% vs. 24.1, p = 0.029), relapse rates (19.4% vs. 10.3%, p = 0.32), and higher mortality rate (54.8% vs. 20.7, p = 0.007) than lower MIF expressers. In addition, high MIF expressers show significantly shorter DFS (12.48 vs. 25.11 months, cumulative survival 38.7% vs. 72.2%, p < 0.01) and inferior overall survival (20.61 vs. 29.74 months, cumulative survival 45.2% vs. 79.3%, p < 0.001) than low MIF expressers. Multivariate cox-regression analysis adjustment confirmed that high MIF expression was the only independent prognostic factor in ALL patients for OS and DFS in our study (p = 0.004, p = 0.01 respectively). CONCLUSIONS: We found that MIF expression is an important prognostic factor in ALL patients with normal karyotype, and its incorporation into novel risk-adapted therapeutic strategies will improve the current cure rates for this group of patients. PMID- 30274022 TI - Boronate Affinity Chromatography Accurately Measures HbA1c also in Patients with End-Stage Renal Disease - Performance Evaluation of the A1c HPLC Analyzer. AB - BACKGROUND: Boronate affinity chromatography is widely used, and the method has lately been improved and designed for HbA1c measurements. We report performance evaluation of the affinity chromatography HbA1c HPLC analyzer. METHODS: Within- and between-run imprecision was assessed based on the results of a series of measurements in three different EDTA blood samples and in control materials. HbA1c levels were measured and compared in 349 EDTA blood samples and 50 samples from patients with end-stage renal disease (ESRD) using the Premier Hb9210 analyzer (affinity chromatography) and the D-10 Hemoglobin Testing System (ion exchange chromatography). RESULTS: The within- and between-run imprecision CVs ranged from 0.72% to 2.01%. Median HbA1c level measured by the Premier Hb9210 was significantly lower (6.4% [46 mmol/mol] vs. 6.6% [49 mmol/mol], p < 0.001). The Passing-Bablok agreement test yielded a slope of 1.0 (95% CI: 1.0 to 1.0) and intercept of -0.1 (95% CI: -0.1 to -0.1). Correlation coefficient and the mean difference amounted to 0.992 and -0.13% (95% CI: -0.11 to -0.15), respectively. Similar results were obtained for HbA1c levels < 7% [< 53 mmol/mol] and >= 7% [>= 53 mmol/mol]. In ESRD patients, median HbA1c level measured by the Premier Hb9210 was also significantly lower (6.0% [42 mmol/mol] vs. 6.5 [48 mmol/mol], p < 0.001) with the mean difference equal to -0.52% (95% CI: -0.59 to -0.46). CONCLUSIONS: Although the Premier Hb9210 gave lower HbA1c levels, good results agreement with the D-10 Hemoglobin Testing System was found. Analytical performance found for HbA1c measurements in ESRD patients was similar. The Premier Hb9210 analyzer is suitable for routine HbA1c testing in clinical practice. PMID- 30274021 TI - Effect of Maternal and Neonatal Factors on Neonatal Thyroid Screening Results. AB - BACKGROUND: Thyroid-stimulating hormone (TSH) levels are an important parameter in screening for congenital hypothyroidism (CH). This study aimed to analyze the effects of birth weight, gestational age, and delivery mode on the incidence of neonatal CH. METHODS: A retrospective cohort study of neonates born in 2015 at a maternity hospital in Xiamen, China and their mothers was conducted. Differences in TSH levels, CH positivity at baseline, and the incidence of CH according to gestational age, birth weight, and delivery mode were assessed using matched neonatal and maternal data. RESULTS: Of the 15,615 enrolled neonates, 150 had positive CH screening results at baseline and nine had confirmed CH. Premature and low-birth-weight neonates had a significantly higher incidence of CH and lower TSH levels when compared to full-term neonates and normal-to-high birth weight neonates, respectively. Neonates delivered vaginally had significantly lower TSH levels and a reduced incidence of baseline CH positivity; cesarean section delivery (odds ratio [OR] = 2.06, p = 0.006) and a maternal TSH level >2.5 mIU/L (OR = 2.37, p = 0.002) were risk factors for CH positivity at baseline. CONCLUSIONS: In this study, the incidence of CH in neonates was associated with gestational age and birth weight. Neonatal baseline CH positivity was positively associated with cesarean delivery and an early-pregnancy maternal TSH level >2.5 mIU/L. PMID- 30274024 TI - Genome-Wide Analysis of mRNA Expression Profiling Identified Lung Cancer-Related Gene in Xuanwei, China. AB - BACKGROUND: The morbidity and mortality of lung cancer in Xuanwei (LCXW) is among the highest in China for both males and females and increases constantly. The underlying molecular changes associated with LCXW are still unclear. The purpose of this study was to screen out potential cancer-related genes which may become promising biomarkers of LCXW. METHODS: Differentially expressed genes (DEGs) were detected by the expression microarrays in 29 paired LCXW tissues (tumor tissue and matched adjacent non-cancerous lung tissues). Integrated with bioinformatic analyses, a literature review was applied for screening out important cancer related genes. An additional 44 paired LCXW samples were collected to verify the transcription and expression levels of the candidate gene by qRT-PCR and Western blotting. The relationship between the candidate genes and clinical pathological features were evaluated using Fisher's test. RESULTS: mRNA expression microarrays revealed that the LCXW patients harbored 2,424 differentially expressed genes (fold change >= 2.0). Of these genes, 1,636 were up-regulated while the other 788 genes were down-regulated. Forty previously reported DNA repair genes associated with PAHs exposure were identified by microarrays. Bioinformatic analyses indicated down-regulated ANXA3 in LCXW patients which was closely related to pathological stage and involved in the regulation of a variety of biological responses. Review of the literature on ANXA3 found its down-regulation was a distinct expression pattern compared with lung cancer occurring in other geographic areas. qRT-PCR and Western blotting confirmed the down-regulation of ANXA3 was associated with LCXW. The correlation analysis of clinical features showed down-regulated ANXA3 was correlated to the progression of pathological stage. CONCLUSIONS: The LCXW patients harbored more DEGs, and these DEGs were involved in a wide range of pathways and biological function damage. We preliminarily suggested ANXA3 may be a potential LCXW related gene. ANXA3 may serve as a promising biomarker for diagnosis of LCXW. PMID- 30274023 TI - Results of Laboratory Tests not Accessed in Brazilian Private Laboratories. AB - BACKGROUND: Laboratory medicine is an important part of the healthcare system and directly contributes to preventive actions, diagnostics, treatment, and management of diseases. The level and quality of the utilization of laboratory resources have been frequently questioned. A dissemination of conflicting data regarding the quantity of laboratory tests not accessed by the requesting doctors or by the patients themselves is observed, although very often the sources and methodologies used to raise those numbers are not properly clarified. The objective of this study was to obtain data about access to results of tests taken in Brazilian private clinical analysis laboratories which use the laboratory information system developed by SHIFT Consultoria e Sistemas. METHODS: Information was extracted from 81 laboratories, which were responsible for the performance of 93,240,651 tests, collected from 7,067,087 patients. RESULTS: The total number of tests not accessed, considering all the regions, was 5,071,454, corresponding to a proportion of 5.4%. In the face of the potential risks of adverse events or impacts in the management of diagnostics and treatments, including economic impacts due to prolonged hospitalization time, the proportion of 17.9% which was found corresponding to tests "not accessed" showing "abnormal" results, is worrisome, mainly if we observe that of those, 2.5% were related to "abnormal" test results processed by laboratories which work in hospital care. CONCLUSIONS: SBPC/ML, in face of the relevance of the theme, will keep stimulating the monitoring and utilization of adequate laboratory resources, in order to allow sustainable healthcare systems. PMID- 30274025 TI - Expression of Plasma miRNA-221 in Colorectal Carcinoma Patients and its Diagnostic Significance in Comparison with p53 Expression. AB - BACKGROUND: Colorectal carcinoma development progresses through a sequence of normal mucosa-polyp-carcinoma. Early detection of premalignancy is crucial for improved outcomes. We evaluated the diagnostic performance of plasma miRNA-221 and its feasibility in discriminating premalignant from malignant neoplasms and correlating it with immunohistochemical p53 expression. METHODS: A total of 109 plasma samples were collected (76 carcinoma, 14 premalignant, and 19 controls). MiRNA221 was quantified by qPCR for calculation of ?Ct using RNU6B as endogenous control. p53 immunohistochemical staining was performed on corresponding tissue. RESULTS: Plasma miRNA-221 and p53 in tissues were significantly overexpressed in the malignant group when compared with the premalignant and control groups. Plasma miRNA-221 was increased in late-stage tumors with nodal or distant metastasis. ROC curve construction for distinguishing between malignant and premalignant tumors revealed a cutoff value of 2.97 with 74% sensitivity, 79% specificity, 73.7% positive predictive value and 78.6% negative predictive value (AUC = 0.824; p = 0.001). Plasma miRNA-221 significantly correlated with p53 in cancer samples (r = 0.507). CONCLUSIONS: MiRNA-221 could have a diagnostic role in differentiating malignant from premalignant neoplasms and could also serve as a predictive marker indicating tumor progression. PMID- 30274026 TI - Chimerism Monitoring by Short Tandem Repeat (STR) Markers in Allogeneic Stem Cell Transplantation. AB - BACKGROUND: Allogeneic hematopoietic stem cell (allo-HSC) transplantation is used in the treatment of malignant hematological diseases. An important tool in monitoring post-transplantation evolution is represented by the percentage of donor's blood cells found in recipient's blood, known as chimersim. This is useful in predicting the graft rejection and the risk of disease relapse. In this study, we present the importance of multiplex STR markers in chimerism monitoring of a 8 year old girl diagnosed with acute lymphoblastic leukemia (ALL). METHODS: In the pre-transplant stage, saliva on buccal swabs and blood samples in EDTA were collected from the donor and recipient and used as reference samples. The DNA extraction from saliva and blood samples was done using the Pure Link Genomic DNA kit (Invitrogen, USA). For the DNA quantification, the Quantifiler Human DNA kit (Applied Biosystems, USA) was used on an ABI 7500 Real-time PCR system (Applied Biosystems, USA). Amplification of the STR markers was performed using the AmpFLSTR NGM SElect kit (Applied Biosystems, USA) on a ProFlex PCR System. The PCR products were separated and detected on an ABI 3500 Genetic Analyzer (Applied Biosytems, USA). RESULTS: One month post-transplantation of HSC, a mixed chimerism (MC) containing 38% of donor's cells was obtained from a bone marrow aspiration sample. On the 45th day, a new transplantation was performed. On the 15th day after 2nd transplantation, a MC with 91% donor's cells was obtained. On the 21st day after the 2nd transplantation, a complete chimerism (CC) with 100% donor's cells was obtained. CONCLUSIONS: Chimerism monitoring is useful in identifying those patients in risk for relapse or graft rejection. PMID- 30274027 TI - Clinical Laboratory - Protagonist in Patient Safety. PMID- 30274028 TI - Relationship Among Antibiotic Resistance, Biofilm Formation and lasB Gene in Pseudomonas Aeruginosa Isolated from Burn Patients. AB - BACKGROUND: Pseudomonas aeruginosa is a major cause of hospital-acquired infection due to its high antibiotic resistance and biofilm formation ability. P. aeruginosa produces elastase lasB during biofilm formation, which can influence properties of biofilm. This study was carried out to evaluate the antibiotic resistance and distribution of the lasB gene among biofilm-producing P. aeruginosa strains isolated from burn patients. METHODS: A total of 128 clinical samples were collected from burn patients. The P. aeruginosa isolates were identified using standard bacteriological procedures. Antibiotic susceptibility test was performed by the disk diffusion method. Biofilm formation was measured by microtiter plate assay. The presence of lasB gene was detected by PCR. RESULTS: A total of 75 samples were positive for P. aeruginosa. A high rate of resistance was seen against ceftriaxone, cefotaxime, and piperacillin/tazobactam. Biofilm formation was seen in 57.3% of the isolates and the prevalence of the lasB gene was 85.3%. Biofilm formation in isolates without lasB was lower and these isolates were more sensitive to imipenem and piperacillin/tazobactam. CONCLUSIONS: In the present study, we did not find a statistically significant relationship among elastase gene (lasB) presence, antibiotic resistance, and biofilm formation in P. aeruginosa strains isolated from burn patients. PMID- 30274029 TI - A Single Step Mutation at D3S1358 Locus in a DNA Paternity Testing with 2 Alleged Fathers. AB - BACKGROUND: Genetic information is used very frequently in human identification in civil or judicial cases. Establishing the kinship relationship between a child and his biological father involves many ethical facts. We describe a DNA paternity case with two alleged fathers and an inconsistency between alleged father-2 and the child at D3S1358 locus. METHODS: As biological samples we used saliva collected from inside the cheek of each person using buccal swabs (Copan, Italy). We collected the biological samples from each of person after each person gave the consent. In order to find the concentration of salivary DNA, the DNA samples were quantified by 7500 ABI Real-time PCR using the Quantifiler Human DNA kit (Applied Biosystems, USA). The next step was the amplification of the Salivary DNA samples by polymerase chain reaction (PCR). It was performed on a ProFlex PCR System (Applied Biosystems, USA) using the multiplex STR markers from the AmpFlSTR(r) Identifiler Plus Amplification Kit (Applied Biosystems, USA). After amplification, the PCR products were run on capillary electrophoresis on an ABI 3500 Genetic Analyzer (Applied Biosystems, USA). RESULTS: AF-1 was excluded as biological father. The DNA profiles of AF-2 and the child had one mismatch at D3S1358 locus. Further, we amplified the Y-STR markers to confirm the mutation, obtaining a perfect match between the 2 persons. CONCLUSIONS: In paternity testing, where one or two inconsistencies are present between the child and the alleged father on autosomal STR markers, the use of haploid markers X-STR or Y STRs is needed for the confirmation or exclusion of paternity.

AB - The main goal of this study was to produce a novel porous scaffold for rapid in vivo bone healing behavior. Lyophilization technique was used to produce this highly porous hybrid scaffold from Na-alginate (S) and hydroxyethylcellulose (HEC) impregnated with different concentration of hydroxyapatite (HA). After cross-linking the scaffolds, their incubation was carried out in simulated body fluid (SBF) for 4 weeks at 37 degrees C to investigate their bioactivity. A number of techniques were employed (e.g., XRD, FTIR, SEM, EDX, and texture analyzer) to characterize the designed scaffolds. It was observed that the mechanical properties of the scaffolds increase deformation energy (182 +/- 16 J/m3) and rigidity gradient (19.44 +/- 0.85 Pa) after loading with HA. Furthermore, the scaffolds were implanted in femur critical size defects (2 mm) of adult male Wistar rats for 6 weeks. In vitro and in vivo analyses demonstrated impressive bioactivity and biocompatibility for the prepared scaffolds, especially those containing HA. Based on the obtained results we conclude that the designed scaffolds are promising solutions for bone regeneration applications. PMID- 30274031 TI - Photostable, hydrophilic, and near infrared quaterrylene-based dyes for photoacoustic imaging. AB - Novel near-infrared contrast agents based on the quaterrylene structure were strategically developed and tested for high photo-stability. Both a dendrimeric quaterrylene molecule, QR-G2-COOH, and a small molecule cationic quaterrylene dye, QR-4PyC4, remain optically stable and continue to generate a competitive photoacoustic response when irradiated by short near-infrared laser pulses for a relatively long time in an in-vitro cell study, unlike indocyanine green that rapidly decreases photoacoustic signal amplitude. The small molecule dye, QR 4PyC4 exhibits not only significantly higher cellular uptake rate than QR-G2-COOH and indocyanine green, but also low toxicity at a concentration of up to 10 MUM. The dendrimeric dye, QR-G2-COOH that has surface functional groups available for conjugation with targeting and therapeutic agents shows the highest photoacoustic amplitude with high optical stability. Therefore, QR-4PyC4 can be a promising universal, sensitive and reliable photoacoustic contrast agent and QR-G2-COOH has great potential as a nano-platform with stable photoacoustic imaging capability. PMID- 30274033 TI - The controllable lanthanum ion release from Ca-P coating fabricated by laser cladding and its effect on osteoclast precursors. AB - Several studies have suggested that rare earth oxides can improve properties of bioceramic coating, and bone resorption of osteoclast can be inhibited by rare earth ion releasing certain concentration. However, the effects of lanthanum ion (La3+) released from Ca-P coating on osteoclast precursors is not clear. In this work, La2O3-doped gradient bioceramic coatings were fabricated on Ti alloy (Ti 6Al-4V) by laser cladding with mixed powders of CaHPO4.2H2O, CaCO3 and La2O3. And the bioactivity, mechanical properties and the La3+ release from coating were investigated in vitro. Human osteosarcoma cells (MG63) were used as a cell model to evaluate the biocompatibility of coatings. Mouse macrophage RAW264.7 cells were cultured on coatings to study the effect of La3+ release from Ca-P coating on osteoclast precursors. The XRD results reveal that the amount of HA + TCP reaches maximum (2theta = 32-33 degrees ) when the content of La2O3 is 0.6 wt%, and the proliferation of MG63 cells is up to highest value, which indicates that compared with other groups, the bioceramic coating with 0.6 wt% La2O3 is of best biocompatibility. Furthermore, the differentiation of RAW264.7 cells into osteoclast could be inhibited by controllable releasing La3+ from Ca-P coating when soaked in SBF, which demonstrates that controllable La3+ release from Ca-P coating is an effective method to prevent osteoclast formation. And a prospective therapy is provided to cure the disease of wear debris in replacement of artificial joint. PMID- 30274032 TI - Durability of self-healing dental composites: A comparison of performance under monotonic and cyclic loading. AB - : Durability is an important quality of dental restorative materials, and the ability to autonomously heal damage incurred during their oral function is highly desirable. OBJECTIVE: The objective was to evaluate the improvement in durability of self-healing dental composites (SHDCs) in terms of their resistance to fracture and capacity for healing of damage under monotonic and cyclic loading. METHODS: SHDCs were prepared by incorporating dental resin composites with microcapsules containing healing liquid. Control specimens with the same mass fraction (5% and 25%) of microcapsules filled with water were also evaluated. Two sets of SHDCs were distinguished by the silane coupling agents that functionalized and bonded the microcapsules to resin network. One set used a methacrylate silane (MA-silane) that connected resin network through covalent bonds, and the other used a H-bonding forming hydroxyl silane (OH-silane). The fatigue crack growth resistance was assessed in terms of the threshold stress intensity range and the conventional Paris Law parameters. Cyclic loading was conducted at 5 Hz with maximum cyclic load ranged between approximately 1 N and 5 N. The efficiency of the autonomous healing was determined per the recovering of the fracture toughness and the extension of fatigue life. RESULTS: The SHDCs with 5 wt% of healing microcapsules exhibited a larger fracture toughness than those with 25 wt% microcapsules. MA-silane SHDCs had approximately five times more responsive microcapsules triggered by fracturing of the composites. Consequently, the MA-silane SHDCs with 5 wt% of microcapsules achieved the best performance in terms of fracture toughness and healing efficiency. In regards to the fatigue crack growth behavior, there was a significant increase in the resistance to fatigue crack growth and 580 +/- 15% improvement in the fatigue life. SIGNIFICANCE: Strong silanization is vital in SHDCs to simultaneously achieve clinically applicable mechanical performance and substantial healing capability. Moreover, the evaluation of self-healing under cyclic loading is a promising tool in quantifying the degree of fracture-induced healing.

AB - Drug delivery systems using nanoparticles can deliver to tumor cells without affecting normal cells. In this study, a novel well dispersed magnetic nano drug was synthesized. Thus, a selective drug delivery system was designed for potential cancer treatment. A new nanocomposite, poly 3,4-dihydroxy-l phenylalanine/Fe3O4 (l-DOPA/Fe3O4), was synthesized and used for targeted Taxol(r) delivery to breast tumor in inbreed Balb/c mice model with or without magnetic field. Fe and Taxol(r) concentrations were measured by flame atomic absorption spectrometry and high-performance liquid chromatography, respectively. Antitumor effectiveness was investigated in terms of tumor growth features. In the presence of magnetic field, Taxol(r) was significantly deposited in tumor tissue in Taxol-nanocomposite-treated group. In addition, the Taxol(r) nanocomposite-treated group with magnetic field showed higher antitumor efficacy than the commercial Taxol and Taxol-nanocomposite without magnetic field. The magnetic nanocomposite is promising for targeted Taxol(r) delivery to breast tumor in a mouse model yielding high performance. PMID- 30274035 TI - "Green-reduced" graphene oxide induces in vitro an enhanced biomimetic mineralization of polycaprolactone electrospun meshes. AB - A novel green method for graphene oxide (GO) reduction via ascorbic acid has been adopted to realize bio-friendly reduced graphene oxide (RGO)/polycaprolactone (PCL) nanofibrous meshes, as substrates for bone tissue engineering applications. PCL fibrous mats enriched with either RGO or GO (0.25 wt%) were fabricated to recapitulate the fibrillar structure of the bone extracellular matrix (ECM) and the effects of RGO incorporation on the structural proprieties, biomechanics and bioactivity of the nano-composites meshes were evaluated. RGO/PCL fibrous meshes displayed superior mechanical properties (i.e. Young's Modulus and ultimate tensile strength) besides supporting noticeably improved cell adhesion, spreading and proliferation of fibroblasts and osteoblast-like cell lines. Furthermore, RGO based electrospun substrates enhanced in vitro calcium deposition in the ECM produced by osteoblast-like cells, which was paralleled, in human mesenchymal stem cells grown onto the same substrates, by an increased expression of the osteogenic markers mandatory for mineralization. In this respect, the capability of graphene-based materials to adsorb osteogenic factors cooperates synergically with the rougher surface of RGO/PCL-based materials, evidenced by AFM analysis, to ignite mineralization of the neodeposited matrix and to promote the osteogenic commitment of the cultured cell in the surrounding microenvironment. PMID- 30274036 TI - Red, green, and blue fluorescent folate-receptor-targeting carbon dots for cervical cancer cellular and tissue imaging. AB - Folate receptor targeted photo-luminescent quantum carbon dots (Fr-CDs) were successfully prepared from folic acid and phenylenediamine isomers through hydrothermal approaches. Fr-CDs were spherical particles smaller than 10 nm, and emit stable green, blue and red luminescence under ultraviolet region excitation (lambdaex = 365 nm) with maximum emissive lengths at 530, 429, and 612 nm. And the corresponding photoluminescence quantum yield as 15.4%, 12.6% and 16.2% respectively. Up-converted photoluminescent properties in near infrared 800 nm spectral region located in green, blue and yellow region. In-vitro studies showed Fr-CDs had almost none cytotoxicity (cell viability over 80%) and high affinitive to the Hela celline highly-expressed-folate-receptor membranes, and lighted on cytoplasm as the fluorescent marker. It displayed long luminescent-stability with PL intensity above 90% in ultraviolet illuminant exposure over 24 h. In in-vivo studies, Fr-CDs were internalized and accumulated in targeted cancer tissues of cervical carcinoma and the emitting fluorescence maintains over 30 min. PMID- 30274037 TI - Promotion of chondrogenic differentiation of mesenchymal stem cells by copper: Implications for new cartilage repair biomaterials. AB - Copper (Cu) has drawn considerable attention in the design of biomaterials due to its multifunction, such as antibacterial property, osteogenic and angiogenic ability. However, the effect of Cu on chondrogenic differentiation of mesenchymal stem cells (MSCs) and its potential for cartilage repair biomaterials has been rarely studied. Here, we report that Cu can significantly enhance chondrogensis of MSCs. Specifically, in vitro studies showed that Cu could promote MSCs cytoskeleton change, extracellular glycosaminoglycan (GAG) deposition and the chrodrogenic genes (Sox9, Aggrecan, and Col-2) up-regulation. Furthermore, we prepared a Cu-containing alginate (Alg) porous scaffold to assess the chondroinductivity of Cu in vivo. In eight weeks, we found that Alg/Cu scaffolds could induce better formation of new cartilage tissue compared to the pure Alg scaffolds fabricated by the same procedure but without adding Cu. These encouraging results indicate that Cu can bring considerable benefits to the development and application of cartilage repair biomaterials. PMID- 30274038 TI - Dynamic imine bond cross-linked self-healing thermosensitive hydrogels for sustained anticancer therapy via intratumoral injection. AB - In this study, we developed a self-healing thermosensitive gel, via dialdehyde functionalized polyethylene glycol (DF-PEG) and beta-glycerophosphate (GP) cross linked chitosan (CS) hydrogels, which enable autonomous self-healing upon damage and sustained release of doxorubicin hydrochloride (DOX) for antitumor therapy via intratumoral injection. The cross-linked gels could exhibit sol-gel transition at 37 degrees C within 5 min and satisfactory in vitro and in vivo healing ability by observing the rejoining and fusion process of scratched gels. Moreover, the in vitro release of DOX loaded cross-linked gels in PBS (pH 6.5 and 7.4) was found to be extended to 13 d. After intratumoral injection in Heps tumor bearing mice, the drug loaded self-healing thermosensitive gels showed a superior tumor inhibition rate (66.12%) than CS thermosensitive hydrogels (53.23%), while the histology studies gave the relieved cardiotoxicity and good biocompatibility of the cross-linked gels. Overall, these cross-linked gels could become a potential local drug delivery system to achieve efficient sustained release, relieved side effects and enhanced therapy efficiency through localized administration. PMID- 30274039 TI - Surface modification of stainless steel for biomedical applications: Revisiting a century-old material. AB - : Stainless steel (SS) has been widely used as a material for fabricating cardiovascular stents/valves, orthopedic prosthesis, and other devices and implants used in biomedicine due to its malleability and resistance to corrosion and fatigue. Despite its good mechanical properties, SS (as other metals) lacks biofunctionality. To be successfully used as a biomaterial, SS must be made resistant to the biological environment by increasing its anti-fouling properties, preventing biofilm formation (passive surface modification), and imparting functionality for eluting a specific drug or capturing selected cells (active surface modification); these features depend on the final application. Various physico-chemical techniques, including plasma vapor deposition, electrochemical treatment, and attachment of different linkers that add functional groups, are used to obtain SS with increased corrosion resistance, improved osseointegration capabilities, added hemocompatibility, and enhanced antibacterial properties. Existing literature on this topic is extensive and has not been covered in an integrated way in previous reviews. This review aims to fill this gap, by surveying the literature on SS surface modification methods, as well as modification routes tailored for specific biomedical applications. STATEMENT OF SIGNIFICANCE: Stainless steel (SS) is widely used in many biomedical applications including bone implants and cardiovascular stents due to its good mechanical properties, biocompatibility and low price. Surface modification allows improving its characteristics without compromising its important bulk properties. SS with improved blood compatibility (blood contacting implants), enhanced ability to resist bacterial infection (long-term devices), better integration with a tissue (bone implants) are examples of successful SS surface modifications. Existing literature on this topic is extensive and has not been covered in an integrated way in previous reviews. This review paper aims to fill this gap, by surveying the literature on SS surface modification methods, as well as to provide guidance for selecting appropriate modification routes tailored for specific biomedical applications. PMID- 30274040 TI - Exploring inhalable polymeric dry powders for anti-tuberculosis drug delivery. AB - The growing interest on polymeric delivery systems for pulmonary administration of drugs anticipates a more direct and efficient treatment of diseases such as tuberculosis (TB) that uses the pulmonary route as the natural route of infection. Polymeric microparticles or nano-in-microparticles offer target delivery of drugs to the lungs and the potential to control and sustain drug release within TB infected macrophages improving the efficiency of the anti-TB treatment and reducing side effects. In a dry powder form these inhalable delivery systems have increased stability and prolonged storage time without requiring refrigeration, besides being cost-effective and patient convenient. Thus, this review aims to compile the recent innovations of inhalable polymeric dry powder systems for the delivery of anti-TB drugs exploring the methods of production, aerodynamic characterization and the efficacy of targeted drug delivery systems using in vitro and in vivo models of the disease. Advanced knowledge and promising outcomes of these systems are anticipated to simplify and revolutionize the pulmonary drug delivery and to contribute towards more effective anti-TB treatments. PMID- 30274041 TI - Recent exploration of bio-mimetic nanomaterial for potential biomedical applications. AB - Bio-inspired materials with the multiscale skeleton show intrinsic multifunctional integration. This special biological characteristic is designed and developed to encourage scientists and engineers to multiobjective artificial physicals with multiscale frameworks. This review focuses on some recent development in the areas of classical biomaterials including lotus leaves, butterfly wings, red rose petals, spider silks and the associated multiscale frameworks acquiring function coalescence. We have also addressed some queries and standpoints for bio-inspired form of drug delivery using pathogens, which sheds light on delivery of proteins, small interfering RNA and other therapeutic agents. PMID- 30274042 TI - Tissue mimicking materials in image-guided needle-based interventions: A review. AB - Image-guided interventions are widely employed in clinical medicine, which brings significant revolution in healthcare in recent years. However, it is impossible for medical trainees to experience the image-guided interventions physically in patients due to the lack of certificated skills. Therefore, training phantoms, which are normally tissue mimicking materials, are widely used in medical research, training, and quality assurance. This review focuses on the tissue mimicking materials used in image-guided needle-based interventions. In this case, we need to investigate the microstructure characteristics and mechanical properties (for needle intervention), optical properties and acoustical properties (for imaging) of these training phantoms to compare with the related properties of human real tissues. The widely used base materials, additives and the corresponding concentrations of the training phantoms are summarized from the literatures in recent ten years. The microstructure characteristics, mechanical behavior, optical properties and acoustical properties of the tissue mimicking materials are investigated, accompanied with the common experimental methods, apparatus and theoretical algorithm. The influence of the concentrations of the base materials and additives on these characteristics are compared and classified. In this review, we assess a comprehensive overview of the existing techniques with the main accomplishments, and limitations as well as recommendations for tissue mimicking materials used in image-guided needle-based interventions. PMID- 30274043 TI - In vitro evaluation of a biomaterial-based anticancer drug delivery system as an alternative to conventional post-surgery bone cancer treatment. AB - Patients diagnosed with osteosarcoma are currently treated with intravenous injections of anticancer agents after tumor resection. However, due to remaining neoplastic cells at the site of tumor removal, cancer recurrence often occurs. Successful bone regeneration combined with the control of residual cancer cells presents a challenge for tissue engineering. Cyclodextrins loaded with chemotherapeutic drugs reversibly release the drugs over time. Hydroxyapatite bone biomaterials coated with doxorubicin-loaded cyclodextrin should release the drug with time after implantation directly at the original tumor site and may be a way to eliminate residual neoplastic cells. In the present study, we have carried out in vitro studies to evaluate such a drug-delivery system and have shown that doxorubicin released from cyclodextrin-coated hydroxyapatite retained biological activity and exhibited longer and higher cytotoxic effects on both cancer (osteosarcoma cells) and healthy cells (primary osteoblasts and endothelial cells) compared to biomaterials without cyclodextrin loaded with doxorubicin. Furthermore, doxorubicin released from biomaterials with cyclodextrin moderately induced the expression of tumor suppressor protein p53 whereas p21 expression was similar to control cells. In addition, hypoxic conditions, which occur after implantation until blood-flow to the area is regenerated, protected endothelial cells and primary osteoblasts from doxorubicin induced cytotoxicity. This chemo-protective effect was far less prominent for the osteosarcoma cells. These findings indicate that a hydroxyapatite-cyclodextrin doxorubicin chemotherapeutic strategy may enhance the drug-targeting effect on tumor cells while protecting the more sensitive healthy cells for a period of time after implantation. A successful integration of such a drug delivery system might allow healthy cells to initially survive during the doxorubicin exposure period, while eliminating residual neoplastic cells. PMID- 30274044 TI - Hierarchical structures on nickel-titanium fabricated by ultrasonic nanocrystal surface modification. AB - Hierarchical structures on metallic implants can enhance the interaction between cells and implants and thus increase their biocompatibility. However, it is difficult to directly fabricate hierarchical structures on metallic implants. In this study, we used a simple one-step method, ultrasonic nanocrystal surface modification (UNSM), to fabricate hierarchical surface structures on a nickel titanium (NiTi) alloy. During UNSM, a tungsten carbide ball hits metal surfaces at ultrasonic frequency. The overlapping of the ultrasonic strikes generates hierarchical structures with microscale grooves and embedded nanoscale wrinkles. Cell culture experiments showed that cells adhere better and grow more prolifically on the UNSM-treated samples. Compared with the untreated samples, the UNSM-treated samples have higher corrosion resistance. In addition, the surface hardness increased from 243 Hv to 296 Hv and the scratch hardness increased by 22%. Overall, the improved biocompatibility, higher corrosion resistance, and enhanced mechanical properties demonstrate that UNSM is a simple and effective method to process metallic implant materials. PMID- 30274045 TI - Molecular encapsulator-appended poly(vinyl alcohol) shroud on ferrite nanoparticles. Augmented cancer-drug loading and anticancer property. AB - Magnetic nanoparticles (MNPs) have the potency to deliver cancer drugs assisted by the application of a magnetic field. In this paper, we present the design of magnesium ferrite nanoparticles of size suitable for drug delivery. A coating polymer, poly(vinyl alcohol), tethered with a tapered cone-shaped cyclic oligosachcharide, beta-cyclodextrin (beta-CD) is synthesized and used to wrap and disperse the MNPs. The magnetic properties are explored using vibrating sample magnetometry and Mossbauer spectroscopy. The ?130 nm MNPs, shrouded with the PVA CD conjugate allows a high amount of the cancer drug, camptothecin, to be loaded on the nanocarrier. Cytotoxicity studies reveal that the loaded drug retains its potency against HEK 293 cells and the cells are sensitive to the treatment by the drug-loaded nanocarrier. PMID- 30274046 TI - Lecithin suspensions for electrophoretic deposition on stainless steel coatings. AB - Lecithin is a mixture of phospholipids (PLs) that are found in living organisms. It gained the interest as a bio- and hemocompatible modifying agent for biomaterials. In this paper, we focused on the elaboration of a simple and well described technology of metals coating with low-cost substance that could be useful in biomaterials industry. We studied the utility of lecithin suspension for stainless steel coating by electrophoretic deposition method. Our goal was to find a relationship between the conditions of lecithin suspension preparation, obtained suspension properties (vesicles size and structure, zeta potential, electrophoretic mobility) and lecithin coating features (topography, roughness). We found that final pH value, zeta potential and electrophoretic mobility of lecithin suspensions were not altered by initial solution pH value. However, the presence of hydrated Na+ ions forced forming of large multi-layered vesicles. We obtained uniform lecithin coatings with the use of electrophoretic deposition, which has a great potential to be used in a large scale. PMID- 30274047 TI - Electrochemical immunosensor based on magnetite nanoparticles incorporated electrospun polyacrylonitrile nanofibers for Vitamin-D3 detection. AB - In the present study, magnetite nanoparticles (Fe3O4 NPs) incorporated polyacrylonitrile nanofibers (PANnFs) having diameter of 350-500 nm, were electrospun and directly collected onto indium tin oxide (ITO) coated glass substrate. X-ray diffraction pattern of Fe3O4-PANnFs confirmed the existence of Fe3O4 NPs within the PANnFs. Nafion was used to make Fe3O4-PANnFs more adhesive to the ITO surface. Partial hydrolyzation of Fe3O4-PANnFs/ITO electrode was done using NaOH solution for the partial conversion of nitrile group (C=N) into carboxyl and amine groups that was confirmed by Fourier transform infrared spectroscopy study. The hydrolyzed Fe3O4-PANnFs/ITO electrode was used as an immobilization matrix for monoclonal antibody specific to Vitamin-D3 (Anti-VD) via 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide and N-Hydroxysuccinimide chemistry. Bovine serum albumin (BSA) was used as a blocking agent to block the non-specific sites onto Anti-VD/Fe3O4-PANnFs/ITO electrode surface. Fabricated BSA/Anti-VD/Fe3O4-PANnFs/ITO immunoelectrode showed improved biosensing parameters for Vitamin-D3 detection such as sensitivity of 0.90 MUA ng-1 mL cm-2, limit of detection of 0.12 ng mL-1and detection range of 10-100 ng mL-1. The association and dissociation constants were obtained as 74.62 ng mL-1, 4.6 ng mL 1, respectively. PMID- 30274048 TI - Synergistic effect of co-immobilized FGF-2 and vitronectin-derived peptide on feeder-free expansion of induced pluripotent stem cells. AB - Expansion of human induced pluripotent stem cells (h-iPSCs) on mouse derived feeder layers or murine cells secretions such as Matrigel hamper their clinical applications. Alternative methods have introduced novel substrates as stem cell niches or/and optimized combinations of humanized soluble factors as fully defined mediums. Accordingly vitronectin as a main part of ECM have been commercialized significantly as a stem cell niche-forming substrate. In this work, we used a functional peptide derived from vitronectin (VTN) and co immobilized it with FGF-2 (as an indisputable ingredient of defined culture mediums) on chitosan film surface. After chemical and physical characterization of the pristine chitosan surface as well as ones modified by VTN or/and FGF-2, h iPS cells were cultured on them at the xeno/feeder-free conditions. Our results demonstrated that co-immobilization of these two biomolecules has a synergistic effect on adhesion and clonal growth of h-iPS cells with maintained expression of pluripotency markers in a FGF-2 density-dependent manner. This is the first report of co-immobilization of an ECM derived molecule and a growth factor for stem cell culture. PMID- 30274049 TI - Collagen-silica nanocomposites as dermal dressings preventing infection in vivo. AB - The controlled delivery of multiple drugs from biomaterials is a timely challenge. In particular the nanocomposite approach offers a unique opportunity to combine the scaffold-forming ability and biocompatibility of hydrogels with the versatile and tunable drug release properties of micro- or nano-carriers. Here, we show that collagen-silica nanocomposites allowing for the prolonged release of two topical antibiotics are promising medicated dressings to prevent infection in wounds. For this purpose, core-shell silica particles loaded with gentamicin sulfate and sodium rifamycin were combined with concentrated collagen type I hydrogels. A dense fibrillar network of collagen exhibiting its typical periodic banding pattern and a homogenous particle distribution were observed by scanning electron microscopy. Antibiotics release from nanocomposites allowed a sustained antibacterial effect against Staphylococcus aureus over 10 days in vitro. The acute dermal irritation test performed on albino rabbit skin showed no sign of severe inflammation. The antibacterial efficiency of nanocomposites was evaluated in vivo in a model of cutaneous infection, showing a 2 log steps decrease in bacterial population when loaded systems were used. In parallel, the histological examination indicated the absence of M1 inflammatory macrophages in the wound bed after treatment. Taken together, these results illustrate the potentialities of the nanocomposite approach to develop collagen-based biomaterials with controlled dual drug delivery to prevent infection and promote cutaneous wound repair. PMID- 30274050 TI - Chitosan/alginate nanoparticles as a promising approach for oral delivery of curcumin diglutaric acid for cancer treatment. AB - Curcumin diglutaric acid (CG) is a prodrug of curcumin that shows better solubility and antinociceptive activity compared to curcumin. To improve its properties further, CG was encapsulated into polysaccharide-based nanoparticles in this study. A chitosan/alginate nanoparticulate system was chosen for encapsulation of CG due to its biocompatibility, biodegradability, non-toxicity, mucoadhisiveness and good film formation. CG-loaded chitosan/alginate nanoparticles were prepared by o/w emulsification and ionotropic gelification, with the conditions optimized using response surface methodology. A chitosan/alginate mass ratio of 0.04:1, CG concentration of 3 mg/mL and Pluronic(r)F127 concentration of 0.50% (w/v) were determined to be optimal for the nanoparticle preparation. FTIR and XRD confirmed encapsulation of CG into the chitosan/alginate nanoparticles. The CG-loaded chitosan/alginate nanoparticles showed better stability under UV radiation and in a simulated gastrointestinal environment, compared to a CG dispersion in water. The nanoparticles showed slow cumulative release of CG in simulated gastrointestinal fluids without enzymes and in body fluid. A Weibull model of the best fit for all conditions suggested that the release pattern of CG from CG-loaded chitosan/alginate nanoparticles was mainly controlled by Fickian diffusion and erosion of polymer materials. Finally, CG-loaded chitosan/alginate nanoparticles showed higher in vitro cellular uptake in human epithelial colorectal adenocarcinoma (Caco-2 cells) and better anticancer activity against Caco-2, human hepatocellular carcinoma (HepG2) and human breast cancer (MDA-MB-231) cells. Therefore, the CG-loaded chitosan/alginate nanoparticles are a promising approach for oral administration of CG for cancer treatment. PMID- 30274051 TI - Bioinspired gold nanoparticles decorated reduced graphene oxide nanocomposite using Syzygium cumini seed extract: Evaluation of its biological applications. AB - The development of novel functionalized reduced graphene oxide nanocomposite materials keeping in mind environmental and health perspectives via green approaches is currently gaining enormous research interest in the field of nanoscience and nanotechnology. Herein, we report a bio-inspired green synthesis approach for gold nanoparticles decorated reduced graphene oxide nanocomposite in which Syzygium cumini seed extract (SCSE) is applied as natural reducing and stabilizing agent for the simultaneous reduction of chloroauric acid and graphene oxide (GO). The obtained nanocomposite was thoroughly investigated using UV visible and FT-IR spectroscopy, XRD, SEM-EDX, TEM-SAED, Raman spectroscopy and XPS analysis. These characterization techniques clearly confirmed the successful synthesis of gold nanoparticles decorated reduced graphene oxide nanocomposite. In addition, this study evaluated the systematic and detailed analysis of AuNPs rGO-NC and its efficacy towards cellular and antibacterial toxicological behavior. A detailed in-vitro cytotoxicity study was performed by analysing the percentage inhibition of cell viability, generation of reactive oxygen species (ROS) in cell lines using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay on human colorectal (HCT116) and lung (A549) cancer cell lines. Further, antibacterial toxicological evaluation was performed by analysing diameter of inhibition Zone (DIZ), activity index (AI), minimum bactericidal concentration (MBC), minimum inhibitory concentration (MIC), growth kinetics (GrK) and death kinetics (DeK) against Gram-negative bacterial strain Escherichia coli and Gram-positive bacterial strains Staphylococcus aureus and Bacillus subtilis. The cytotoxicity and antibacterial toxicological assays revealed that the synthesized nanocomposite showed significant anti-cancer activity towards A549 cell line and Gram-negative bacterial strain Escherichia coli compared to the rest. PMID- 30274052 TI - Multifunctional graphene-based magnetic nanocarriers for combined hyperthermia and dual stimuli-responsive drug delivery. AB - The synthesis of hydrophilic graphene-based yolk-shell magnetic nanoparticles functionalized with copolymer pluronic F-127 (GYSMNP@PF127) is herein reported to achieve an efficient multifunctional biomedical system for mild hyperthermia and stimuli-responsive drug delivery. In vitro tests revealed the extraordinary ability of GYSMNP@PF127 to act as smart stimuli-responsive multifunctional nanomedicine platform for cancer therapy, exhibiting (i) an outstanding loading capacity of 91% (w/w, representing 910 MUg mg-1) of the chemotherapeutic drug doxorubicin, (ii) a high heating efficiency under an alternating (AC) magnetic field (intrinsic power loss ranging from 2.1-2.7 nHm2 kg-1), and (iii) a dual pH and thermal stimuli-responsive drug controlled release (46% at acidic tumour pH vs 7% at physiological pH) under AC magnetic field, in just 30 min. Additionally, GYSMNP@PF127 presents optimal hydrodynamic diameter (DH = 180 nm) with negative surface charge, high haemocompatibility for blood stream applications and tumour cellular uptake of drug nanocarriers. Due to its physicochemical, magnetic and biocompatibility properties, the developed graphene-based magnetic nanocarrier shows high promise as dual exogenous (AC field)/endogenous (pH) stimuli responsive actuators for targeted thermo-chemotherapy, combining magnetic hyperthermia and controlled drug release triggered by the abnormal tumour environment. The presented strategy and findings can represent a new way to design and develop highly stable added-value graphene-based nanostructures for the combined treatment of cancer.

AB - Adulteration of medicinally valuable curcumin (CU) with harmful chemicals as metanil yellow (MY) in recent years have demanded for quick detection techniques of the adulterants. The voltammetric behavior of CU and MY on bare glassy carbon electrode (BGCE) and carbon quantum dots modified glassy carbon electrode (CQDs/GCE) was studied by both cyclic voltammetry (CV) and differential pulse voltammetry (DPV) in phosphate buffer solution of pH 5.4. The MY responded to the CQDs/GCE with two anodic peaks at -0.004 V and 0.136 V and two cathodic peaks at 0.112 and -0.048 V. Under similar conditions CU exhibited two anodic peaks at 0.28 V and 0.55 V and one cathodic peak at 0.25 V. The overlapped voltammogram obtained for CU and MY on BGCE was well separated on the CQDs/GCE. The interference studies revealed that the compounds, demethoxycurcumin and bisdemethoxycurcumin, which are commonly associated with CU, did not interfere with the detection of MY. Real sample was analyzed with fabricated electrode and the recovery values >98% were obtained. PMID- 30274054 TI - Bioadhesive immobilize agarase on magnetic ferriferous by polydopamine. AB - The combined action of dopamine-iron coordination reaction and dopamine self polymerization was employed to immobilize agarase on the surface of Magnetic ferriferous oxide (MFO). The solid-liquid separation was easily realized in magnetic field due to the magnetic carrier. The immobilization process was taken by dopamine self-polymerization in room temperature, aqueous solution and neutral pH without organic solvent. Magnetic ferriferous oxide was prepared through coprecipitation. Then, MFO and dopamine were reacted under mild conditions to prepare the magnetic ferriferous oxide-polydopamine (MFO-PDA) complex. The MFO PDA complex was used in enzyme immobilization. It showed that the average enzyme activity yield was 63.9% in Immobilized enzyme, and the relative enzyme activity of the immobilized enzyme was still above 50% even after five times of reuse in addition, the MFO-PDA complex had good immobilization capacity toward agarase, and the immobilized enzyme has good reusability.

AB - Beyond providing barrier function, the advanced materials in guided tissue regeneration (GTR) concept are further prompt to foster regeneration of distinct interfacing tissues. Herein we develop chitosan (CHT)/gelatin (GEL) bilayer membranes via successive solvent- and freeze-casting procedures and genipin (GEN) cross-linking chemistry. By utilizing the autofluorescence signal from GEN cross linking products (i.e. the secondary CHT (GEL) amines and GEN esters), the Confocal Fluorescent Microscopy (CFM) identifies the chemical inter-linking as well as physical integration between interface layers. The presence of non- and highly MU-porous and pore-interconnecting regions is demonstrated within cross sections of membranes with (by weight) prevalent GEL contribution in contrast to the sheet-like organization in membrane with equal presence of components. The constant processing conditions on variable compositions did not significantly affect the pore size distributions (in 1-230 MUm range), while pore wall thickness increase up to 220 MUm with GEL increase, which also improves the yield stress at compression (from 10 kPa to 19 kPa) and elastic modulus (from 26 kPa to 34 kPa). The rapid mineralization procedure resulted in deposition of non-regular to spherical minerals, containing nonstoichiometric carbonated apatite with Ca/P ration in 1.7-2 range, which demonstrates formation of osseointegrative interface. The fast and high (up to 580%), composition-dependent swelling, as well as 67% to 100% weight loss in 4 weeks in vitro degradation experiment point on membranes' relevance in GTR. PMID- 30274056 TI - Evaluation of antibacterial and cytotoxic properties of green synthesized Cu2O/Graphene nanosheets. AB - Graphene nanocomposites have received attention for the therapy and detection of diseases. In this study, we developed a simple and green chemistry approach for synthesizing Cu2O/graphene nanocomposites (Cu2O/G) using date palm fruit syrup as a reducing agent. The graphene oxide surface anchored with Cu(OH)2 and reduced it to fabricate Cu2O-anchored graphene nanosheets using date palm fruit syrup. Physicochemical characteristics of the synthesized nanocomposites were analyzed. Scanning electron microscopy images revealed 50-70 nm Cu2O nanostructures anchored on the surface of crumpled graphene sheets. The Cu2O/G nanocomposites inhibited the gram-negative and gram-positive bacterial growth at 300 MUg. When compared with Cu2O nanoparticles and graphene oxide nanosheets (GO), Cu2O/G nanocomposite exhibited outstanding bactericidal activity. The cytotoxic properties of the prepared nanocomposites were studied in human mesenchymal stem cells (hMSCs). The Cu2O/G nanocomposites did not reduced cell viability by up to 200 MUg/mL and slightly induced cell death at high concentrations. However, Cu2O nanoparticles and GO have significantly reduced the cell viability in hMSCs. The microscopic images of cellular and nuclear morphology suggested that the Cu2O/G composites did not cause major changes to hMSCs. The Cu2O nanoparticles and GO remarkably triggers the cellular damages, nuclear condensation and DNA fragmentation in hMSCs. Our study results revealed that Cu2O/G has excellent antibacterial activity with good biocompatibility. Thus, Cu2O/G could be used as a promising antibacterial agent in various purposes. PMID- 30274057 TI - Synthesis, characterization & cytocompatibility of poly (diol-co-tricarballylate) based thermally crosslinked elastomers for drug delivery & tissue engineering applications. AB - The aim of this study was to investigate the synthesis and in vitro characterization of thermoset biodegradable poly (diol-co-tricarballylate) (PDT) elastomeric polymers for the purpose of their use in implantable drug delivery and tissue engineering applications. The synthesis was based on thermal crosslinking technique via a polycondensation reaction of tricarballylic acid with aliphatic diols of varying chain lengths (C6-C12). PDT prepolymers were synthesized at 140 degrees C for 20 min. After purification, the prepolymers were molded and kept at 120 degrees C for 18 h under vacuum to complete the crosslinking process. PDT prepolymers were characterized by DSC, FT-IR, 1H NMR and GPC. The PDT elastomers were also subjected to thermal and structural analysis, as well as sol content, mechanical testing, in vitro degradation and cytocompatibility studies. The mechanical properties and sol content were found to be dependent on synthesis conditions and can be controlled by manipulating the crosslinking density and number of methylene groups in the chain of precursor aliphatic diol. The family of thermally crosslinked PDT biodegradable polyesters were successfully prepared and characterized; besides they have promising use in drug delivery and other biomedical tissue engineering applications. PMID- 30274058 TI - Manipulation of osteoclastogenesis: Bioactive multiphasic silica/collagen composites and their effects of surface and degradation products. AB - The intent of the present study was to demonstrate that multiphasic silica/collagen xerogels are able to manipulate cellular processes. These xerogels were prepared by a sol-gel approach allowing the incorporation of mineral phases. The resulting nanocomposites are designed as biomaterial for bone regeneration. Human osteoclasts derived from peripheral blood mononuclear cells were cultured both indirectly and directly, either in presence of different xerogel types or on their surface, to investigate the factor with the main influence on osteoclastogenesis. To this end, the incorporation of a third phase to silica/collagen xerogels was used to affect osteoclastogenesis. In cell culture, ambient ion conditions controlled by both the degradation products of the xerogel and the bioactivity-dependent ion release and reprecipitation were shown to have the main effect on osteoclast specific enzyme tartrate-resistant acid phosphatase (TRAP) 5b. Late stage of osteoclastogenesis characterized by resorption was strongly dependent on the xerogels composition. Surface chemistry of the xerogels was displayed to play an important role in osteoclast resorption. Biphasic silica/collagen xerogels and triphasic xerogels with calcium carbonate offered widespread resorbed areas, whereas hydroxyapatite containing xerogels showed distinctly reduced resorption. The incorporation of strontium carbonate and phosphate, respectively, as third phase changed TRAP 5b activity dose dependently and inhibited resorption within 21 days. Quantitative evaluation on osteoclast differentiation was carried out using biochemical methods (TRAP 5b, cathepsin K) and was supported by confocal laser scanning microscopy and scanning electron microscopy (SEM). Qualitative estimation of resorption was carried out by SEM. PMID- 30274059 TI - Insights on the intracellular trafficking of PDMAEMA gene therapy vectors. AB - It is known that an efficient gene therapy vector must overcome several steps to be able to express the gene of interest: (I) enter the cell by crossing the cell membrane; (II) escape the endo-lysosomal degradation pathway; (III) release the genetic material; (IV) traffic through the cytoplasm and enter the nucleus; and last (V), enable gene expression to synthetize the protein of interest. In recent years, we and others have demonstrated the potential of poly(2-(N,N' dimethylamino)ethylmethacrylate) (PDMAEMA) as a gene therapy vehicle. Further optimization of gene transfer efficiency requires the understanding of the intracellular pathway of PDMAEMA. Therefore the goal of this study was to determine the cellular entry and intracellular trafficking mechanisms of our PDMAEMA vectors and determine the gene transfer bottleneck. For this, we have produced rhodamine-labeled PDMAEMA polyplexes that were used to transfect retinal cells and the cellular localization determined by co-localization with cellular markers. Our vectors quickly and efficiently cross the cell membrane, and escape the endo-lysosomal system by 24 h. We have observed the PDMAEMA vectors to concentrate around the nucleus, and the DNA load to be released in the first 24 h after transfection. These results allow us to conclude that although the endo lysosomal system is an important obstacle, PDMAEMA gene vectors can overcome it. The nuclear membrane, however, constitutes the bottleneck to PDMAEMA gene transfer ability. PMID- 30274060 TI - Praziquantel systems with improved dissolution rate obtained by high pressure homogenization. AB - Praziquantel (PZQ), an antihelmintic agent commonly administered to humans and cattle, has low aqueous solubility, which compromises its bioavailability and efficacy. The purpose of this study was to develop a new formulation, in order to improve PZQ dissolution rate. PZQ dispersions have been developed by high pressure homogenization (HPH) using different stabilizers, selected upon PZQ saturation solubility. After the screening, two promising formulations were developed, combining poloxamer 188 with polyvinylpyrrolidone or maltodextrin. Characterization studies including particle size distribution, crystallinity, morphology, drug content, and in vitro dissolution profiles, were performed over selected formulations. The scanning electronic micrographs revealed that the morphology of suspended particles corresponded to elongated shapes, with an average particle size close to the micron range. X-ray powder diffractometry and differential scanning calorimetry results confirmed the drug crystallinity, before and after the HPH process. Besides, differential scanning calorimetry revealed the absence of interactions between PZQ and excipients. The dissolution rate of PZQ dispersions was significantly enhanced compared with raw PZQ, either in phosphate buffer or hydrochloric acid, mainly due to particle size reduction, thus improved saturation solubility. PMID- 30274061 TI - Incorporation of zinc oxide nanoparticles improved the mechanical, water vapor barrier, UV-light barrier, and antibacterial properties of PLA-based nanocomposite films. AB - Zinc oxide nanoparticles (ZnO NPs) were synthesized using zinc chloride and NaOH and they were incorporated to prepare PLA/ZnO NPs composite films. The SEM images showed that the ZnO NPs were cubical in shape with size ranged from 50 to 100 nm, and the PLA/ZnO NPs composite films were smooth and compact. The composite films exhibited strong UV-light barrier property with a slight decrease in the transparency. The thickness, tensile strength, and water vapor barrier property of the films increased significantly after incorporation of ZnO NPs. The TS of PLA films increased by 37.5%, but the WVP decreased by 30.5% from 3.11 * 10-11 to 2.16 * 10-11 g m/m2.Pa.s when 0.5 wt% of ZnO NPs was incorporated. The composite films exhibited potent antibacterial activity against food-borne pathogenic bacteria, Escherichia coli and Listeria monocytogenes. The developed films were applied to the packaging of a minced fish paste and showed strong antibacterial function. The prepared composite films could be used as antibacterial and UV light barrier films for food packaging and biomedical applications. PMID- 30274062 TI - A method for visualization and isolation of elastic fibres in annulus fibrosus of the disc. AB - A simple and cost effective protocol for visualization and isolation of the elastic fibres network in the annulus fibrosus (AF) of the disc is explained, to provide other researchers a method that can be applied in disc ultra-structural analysis, biomechanical assessment of elastic fibre and tissue engineered scaffold fabrication. This protocol is developed based on simultaneous sonication and alkali digestion of tissue that eliminates all matrix constituents except for elastic fibres, which is applicable for different species including human. Thin samples harvested from ovine, bovine, porcine and human, which are commonly used in disc research, were exposed to 0.5 M sodium hydroxide solution along with sonication (25 kHz) in distilled water for defined periods of time at room temperature. Post heat treatment removed collagen fibres via the gelatinization process, for visualization of elastic fibres. PMID- 30274063 TI - The physical features -size and granularity- of solid materials are strongly affected by trituration in lactose, before turning them into homeopathic solutions. AB - Trituration is a mechanical process (a form of comminution) for reducing the particle size of a substance. In this manuscript, six different Raw Solid Materials (RSM) which are used in Homeopathy after successive grindings are studied before they are turned into homeopathic solutions. The impact of trituration, with the presence of alpha-lactose monohydrate (milk sugar) seems to be quite great and interesting because of the variety of grain size which largely differentiate the properties of the materials. The grain sizes obtained triturations by hand according to C. Herring's suggestion leads, finally, measurement scale dimensions. The obtained results can be useful information for all the pharmacy industries, as well as for preparing any kind of powder. PMID- 30274064 TI - Fabrication, antibacterial activity and cytocompatibility of quaternary ammonium chitooligosaccharide functionalized polyurethane membrane via polydopamine adhesive layer. AB - In this study, to enhance the antibacterial activity and cytocompatibility of the electrospinning polyurethane (PU) fibrous membrane, quaternary ammonium chitooligosaccharide (G-COS) was immobilized on the fibrous membrane surface via an intermediate layer of polydopamine (PDOPA) to obtain the G-COS functionalized PU (G-C-D-PU), as a control, chitooligosaccharide (COS) functionalized PU fibrous membrane (C-D-PU) was prepared, too. Surface composition, morphology, hydrophilicity and surface energy of the original and modified PU fibrous membranes were characterized, which revealed that the surface roughness and hydrophilicity of the PU fibrous membrane were obviously increased by modified with COS and G-COS, respectively. Antibacterial experiment against E. coli and S. aureus indicated that antibacterial activity of the G-C-D-PU fibrous membrane was markedly superior to that of pure PU and C-D-PU fibrous membranes. In vitro cells culture experiments revealed that the adhesion and proliferation of NIH-3T3 cells on the PU fibrous membrane were improved by successively immobilized with PDOPA and COS as well as G-COS with the concentration of 2 g/L and 6 g/L. Moreover, the G-C-D-PU fibrous membranes with relative high G-COS content were more beneficial to the enhancement of antibacterial activity, but on the contrary, those with relative low G-COS content were more in favor of cell attachment and proliferation. PMID- 30274065 TI - Enhanced biocompatibility of PAMAM dendrimers benefiting from tuning their surface charges. AB - The surface charge of dendrimers is one of the key factors that determine their use in nanomedicine. Generation 5 poly(amido amine) dendrimers (G5 PAMAM) encapsulating with fluorescein sodium were employed to study the method to tune surface charge. Firstly, the surface primary amines were reacted with maleic anhydride to introduce double bonds. Then, l-cysteine and cysteamine were conjugated to these double bonds via thiol-ene additions in water, respectively. The surface charges of modified G5 PAMAMs were successfully controlled by tuning the molar ratio of L-cysteine to cysteamine. The surface charges of the resulting modified G5 PAMAMs varied from -16.0 mV to -3.7 mV at physiological pH. In addition, they showed good compatibility with proteins and cells compared with G5 PAMAM. Modified G5 PAMAMs and fibrinogen could coexist in solution without generating noticeable aggregation, while G5 PAMAM induces significant aggregation, indicating these modifications can effectively reduce the interaction force between G5 PAMAM and proteins. Furthermore, modified G5 PAMAMs exhibited negligible hemolysis, while G5 PAMAM caused severe hemolysis. The cytotoxicity assay demonstrated that modified G5 PAMAMs exhibited very low cytotoxicity to both HUVEC cells and KB cells (>90% cell viability) at high concentrations up to 2 mg/mL. The cellular uptake of them was much less efficient compared with that of G5 PAMAM. Moreover, the intravenous injected modified G5 PAMAMs were excreted by kidney with a relatively little accumulation in liver, confirming their good biocompatibility in vivo. It is expected that the modified G5 PAMAMs could be an excellent candidate for contrast agent carriers in the future. PMID- 30274066 TI - Studies on effect of CuO addition on mechanical properties and in vitro cytocompatibility in 1393 bioactive glass scaffold. AB - Copper doped bioactive glasses have been reported as the potential biomaterial for diseased or damaged bone repair and act as stimulants to new bones formation. In the present manuscript, we have synthesized 1393 derived glass based scaffold with the general formula of (54.6 - X)SiO2.6Na2O.7.9 K2O.7.7 MgO.22 CaO.1.74 P2O5.XCuO (all are in mole%; where X = 0,1,2,3) through traditional melt-quench route and the samples were designated as 1393, 1393-1Cu, 1393-2Cu and 1393-3Cu respectively. Polymer foam with interconnected pores has been used on later stage to prepare porous (porosity > 50%) bioactive scaffolds. The addition of CuO in glass scaffolds was to ensure its cytocompatibility, ability to enhance cell proliferation and improvements in mechanical properties. Increasing trend of CuO in the 1393 glass scaffold has resulted in increasing compressive and flexural strength and elastic modulus of the scaffolds. In-vitro cellular growth inhibition and cell viability assay of CuO incorporated 1393 glass scaffolds demonstrated that it did not inhibit proliferation and viability of human squamous carcinoma cell (SCC-25) at low materials concentration. The materials caused moderate level of apoptosis at higher concentrations and were also tolerated by human RBC as studied by hemolytic assay. The results indicated that CuO incorporated 1393 scaffolds could be a potential biomaterial for neobone tissue engineering application. PMID- 30274067 TI - Fabrication and characterization of PCL/zein/gum arabic electrospun nanocomposite scaffold for skin tissue engineering. AB - The main role of tissue engineering is to produce the artificial tissue for replacing the biological functions in tissue regeneration and wounds healing. The purpose of this research was to produce porous nanofiber scaffold by electrospinning to compensate deep skin damages. In order to simulate a scaffold similar to the natural extracellular matrix of the skin, a mixture of corn protein (Zein), polycaprolactone (PCL) and gum arabic (GA) was used with different concentrations and ratios. Zein and GA polymers were used as a protein and polysaccharide component of the scaffold and PCL polymer for elasticity, strength and time setting of scaffold degradability. For investigating morphology and scaffold compounds, scanning electron microscopy (SEM) and Fourier transform infrared techniques were used. Furthermore, mechanical properties, porosity, water absorption and degradability in phosphate buffered saline (PBS) were investigated. Antibacterial properties, cell adhesion and proliferation were also evaluated. SEM results showed that fabricated PCL/Zein/GA scaffolds had a porous structure with bimodal diameters distribution. PCL/Zein/GA scaffolds showed high hydrophilic properties, favorable porosity (about 80%) and tensile strength of 1.36-3 MPa with an elongation of 19.13-44.06% desirable for skin tissue engineering. SEM images of degraded specimens show that the scaffold retains its fibrous structure during its destruction. The results of bacterial culture indicated that the scaffold containing GA had antibacterial properties. Moreover, in vitro assays revealed favorable L929 cells proliferation compared to tissue culture polystyrene (control). Hence, the PCL/Zein/GA scaffold shows a good potential for application in skin tissue engineering. PMID- 30274068 TI - Inner layer-embedded contact lenses for ion-triggered controlled drug delivery. AB - Drug leakage during manufacturing and storage process is the main obstacle hindering the application of contact lenses as the carrier for extended ocular drug delivery. In this study, we have designed a novel inner layer-embedded contact lens capable of ion-triggered drug release for extended ocular drug delivery. Using betaxolol hydrochloride as a drug model, drug-ion exchange resin complex dispersed polymer film was used as an inner layer, and silicone hydrogel was used as an outer layer to fabricate inner layer-embedded contact lens. Influence of composition of the inner film and crosslinking degree of the outer hydrogel on drug release profile was studied and optimized for weekly use. The ion-triggered drug eluting property enables the inner layer-embedded contact lens being stable when stored in distilled water at 5 degrees C for at least 30 days with ignorable drug loss and negligible changes in drug release kinetics. In vivo pharmacokinetic study in rabbits showed sustained drug release for over 168 h in tear fluid, indicating significant improvement in drug corneal residence time. A level A IVIVC was established between in vitro drug release and in vivo drug concentration in tear fluid. In conclusion, this inner layer embedded contact lens design could be used as a platform for extended ocular drug delivery with translational potential for both anterior and posterior ocular disease therapy. PMID- 30274069 TI - Development of biodegradable electrospun gelatin/aloe-vera/poly(epsilon caprolactone) hybrid nanofibrous scaffold for application as skin substitutes. AB - Nowadays, aloe-vera (AV) is exploited extensively in nanofibrous structures for skin substitutes. However, the lack of electrospinnability and appropriate mechanical characteristics are the key limitations for this natural extract to be used in the form of nanofibrous mats. In this study, two commercially available biopolymers, gelatin (Gel) and poly(epsilon-caprolactone) (PCL), were chosen to improve these issues and double-nozzle electrospinning technique was used to fabricate hybrid scaffold from Gel/AV blend and PCL solutions. Response surface methodology was utilized to investigate the effect of electrospinning parameters (Gelatin concentration, Aloe-vera concentration and Gel/AV feed-rate) on the mechanical properties, morphology and hydrophilicity of nanofibers and the optimized scaffold was chosen for further studies. In order to verify the application of this scaffold in bioapplications, the chemical, thermal and biological features of scaffold were analyzed using FTIR, DSC, biodegradability, bactericidal, biocompatibility and drug-delivery. The results revealed that the presence of aloe-vera improved the antibacterial activity (>99% and 85.63% against Gram-positive and Gram-negative bacteria, respectively), and led to adequate in-vitro biodegradation. Furthermore, it was found that incorporation of aloe-vera increased the cell viability without any toxicity. PMID- 30274070 TI - Long-term real-time tracking live stem cells/cancer cells in vitro/in vivo through highly biocompatible photoluminescent poly(citrate-siloxane) nanoparticles. AB - Long-term live cell tracking is desirable and necessary to understand the dynamics and complexity of biological interactions in stem cells and cancer cells. Conventional live cells fluorescence trackers are generally non-degradable and are showing increased toxicity concerns during the long-term application. Previously we developed biodegradable fluorescent poly(citrate)-based hybrid elastomers for bone regeneration applications. Here, we fabricated the photoluminescent poly(citrate-siloxane) nanoparticles (PCSNPs) through an oil/water emulsion method and demonstrated their long-term live stem cells/cancer cells imaging applications. PCSNPs showed a uniform size distribution (mean diameter 120 nm) and highly stable dispersability (above 30 days) in various physiological medium, as well as excellent fluorescent properties and photostability. PCSNPs possess excellent cellular biocompatibility, which could be efficiently internalized by cells and selectively image the cell lysosome with a high photostability. Compared with commercial Cell TrackerTM Green and Cell TrackerTM Red, the adipose-derived mesenchymal stem cells or human hepatoma cells were stably labeled by PCSNPs for over 14 days as they grew and developed (7 passages). Additionally, PCSNPs efficiently tracked cells up to 7 days in vivo through a non-invasively way compared with 1 day of commercial tracker. This study demonstrates an important strategy to design biodegradable multifunctional delivery platforms for biomedical applications such as long-term bioimaging. PMID- 30274071 TI - Controlled release of monoclonal antibodies from poly-l-lysine-coated alginate spheres within a scaffolded implant mitigates autoimmune responses to transplanted islets and limits systemic antibody toxicity. AB - Immunomodulatory monoclonal antibodies (IM-mAbs) are a cornerstone of modern immunotherapy; however, when administered systemically (i.e., via injection), these agents can generate a variety of negative side effects. For many diseases, systemic delivery of IM-mAbs is the most effective mode of treatment, but in instances where the cellular target occupies a limited, well-defined space (e.g., solid tumors or cellularized implants) local, controlled release of IM-mAbs might be desirable. Antibodies are highly sensitive to a variety of environmental conditions, which limit the kinds of polymers suitable for antibody retention and controlled release. The present study evaluates the release of antibodies from biocompatible, 2-mm diameter alginate spheres coated with poly-l-lysine and a thin outer layer of alginate (APA spheres). In vitro, rates of antibody release (including IM-mAbs) could be incrementally decreased and made linear by incrementally increasing the quantity of poly-l-lysine deposited on the alginate, with linear release lasting in one scenario for at least 46 days. To evaluate the bioactivity in vivo of IM-mAbs, APA spheres loaded with either anti-CD3epsilon or anti-CD95 mAb were incorporated into scaffolded islet implant (SI) test-beds and the SIs implanted into a mouse model of autoimmune (type 1) diabetes. Release of mAbs within the implanted SIs resulted in reduced autoimmune responses to both transplanted and native islets. Notably, mice implanted with APA spheres loaded with quantities of anti-CD95 mAb that would be lethal if given systemically showed immunomodulation with no toxic side effects. Collectively, our results indicate that APA spheres are a relatively simple means to evaluate the effects of local, controlled release of IM-mAbs in a way that preserves mAb function and limits systemic toxicity. PMID- 30274072 TI - Precise design and synthesis of an AIE fluorophore with near-infrared emission for cellular bioimaging. AB - Organic fluorophores emerge as important stains for bioimaging and biosensing, especially for fluorophores with aggregation-induced emission characters. However, the development of organic fluorophores with efficient AIE properties expand to far-red and/or near-infrared is still a great challenge. Herein, we precisely design and synthesize a novel D-pi-A type of near-infrared AIE fluorophore (TPE-PTZ-R) by introducing phenothiazine (PTZ) to modify the typical AIE unit (tetraphenylethylene, TPE). TPE-PTZ-R displays good optical properties including a large Stokes shift and typical AIE properties. We next fabricate the uniform and stable AIE nanoparticles by loading Pluronic F127 and apply it in cellular bioimaging with high uptake efficiency, low cytotoxicity and good photostability. PMID- 30274073 TI - Mesoporous silicas templated by heterocyclic amino acid derivatives: Biomimetic synthesis and drug release application. AB - The present paper reported a biomimetic synthesis of mesoporous silicas (BMSs) at room temperature by using synthesized polymers (C16-l-His, C16-l-Pro and C16-l Trp) which derived from amino acid with ring structures as template under basic condition via co-structural-directing-agent method. The formation mechanism of BMSs and effect of initial synthesis conditions (such as surfactant structure, pH and co-solvents) on morphology and structure of BMSs were systematically studied. Synthesized BMSs were characterized by transmission electron microscope (TEM), X ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and nitrogen adsorption/desorption isotherms. The results showed that the surfactant structure was the dominant factor to direct the final mesostructure of BMSs, since the structure of surfactant affected the structure and size of clusters. Meanwhile the generation of BMSs required very rigorous alkaline condition which controlled the ionization degree of the surfactant and thus contributing to adequate stacking energy. Higher pH resulted in construction of channels with higher curvature. The presence of ethanol was found to facilitate the formation of BMSs with larger particle size. In application, aspirin can be loaded into BMSs with high efficiency, and the drug crystalline state of aspirin transformed from crystalline state to amorphous state during this process, which undoubtedly lead to the improvement of drug dissolution from 72.8% to 100% within 90 min. It is convincible that the biomimetic method presented here provided novel insight on precisely control of mesoporous silica and undoubtedly promoted the application of mesoporous silica materials. PMID- 30274074 TI - Electrospun mucosal wound dressings containing styptics for bleeding control. AB - Two major aspects need to be focused to accelerate wound healing of mucosal damages especially in the field of otorhinolaryngology. (i) The problem of application due to the small access during surgery, (ii) the fixation of the wound dressing to reveal a stable healing process. In the present work the high request to a mucosal wound dressing which additionally support hemostasis was addressed. We developed an electrospun fabric made of poly(l-lactide-co-d/l lactide) (PLA) which can be loaded with the hemostatic agents adrenaline and tranexamic acid to cover mucosal lesions analogues to common skin patches. These loaded electrospun fabrics were demonstrated to be biocompatible, thin and flexible, and thus could be adapted individually to the mucosal defect with respect to localization and size of the lesion. The treatment of mucosal defects with these loaded PLA wound dressings induced a faster and time controlled hemostatic reaction, which significantly improved the healing process. PMID- 30274075 TI - Synthesis of fluorescent silicon quantum dots for ultra-rapid and selective sensing of Cr(VI) ion and biomonitoring of cancer cells. AB - A facile one-step synthetic approach was developed for fabrication of fluorescent silicon quantum dots (Si QDs) and used as a probe for fluorescence detection of hexavalent chromium (Cr (VI)) in environmental water samples. The as-prepared Si QDs exhibit a strong fluorescence emission peak at 520 nm with a quantum yield of 14.2%. The fluorescent Si QDs were rapidly produced by using ascorbic acid as a reductant at 55 degrees C. The emission peak of Si QDs at 420 nm was effectively quenched upon the addition of Cr(VI). The Si QDs acted as the best fluorescent probe for the detection of Cr(VI) at PBS pH 7.4. The developed probe possessed a good linear correlation (R2 = 0.992) between Cr(VI) concentration (1.25-40 MUM) and the (F0-F)/F0 values with a detection limit of 0.65 MUM. Furthermore, the Si QDs served as a bio-probe for fluorescence imaging of A549 lung cancer cells and cell viability results confirmed the good biocompatible nature of Si QDs. The as fabricated Si QDs show several advantages such as rapidity, selectivity and biocompatibility for sensing of Cr(VI) and imaging of A549 cells, which opens a facile analytical platform for environmental and bioimaging applications. PMID- 30274076 TI - Molecular analysis of biocompatibility of anodized titanium with deposited silver nanodendrites. AB - Titanium (>99.6% purity) and its anodically oxidized modifications, with and without deposited silver nanodendrites regarding its biocompatibility were evaluated. In human gingival fibroblasts and osteoblast cell lines grown on tested samples, the level of expression of genes encoding alphaV (ITGAV) and beta1 (ITGB1) integrin subunits also genes encoding focal adhesion (FAK) and extracellular-signal regulated (ERK) kinases was assessed. For this purpose, the qualitative and quantitative PCR technique was used. The expression of studied genes was dependent on the origin of cell lines and the type of evaluated material. The high expression of PBGD and ITGAV genes in fibroblasts grown on the surface of anodically modified titanium with deposited silver nanodendrites indicates potentially high biocompatibility of these samples for soft tissue cells. The high expression of the ITGB1 and ERK1 genes and the enhanced expression of the FAK gene in osteoblasts cells grown on the tested material was also observed. Summarizing, the nanocrystalline Ti modified with silver deposits showed higher biocompatibility in comparison with the conventional pure Ti samples. PMID- 30274077 TI - Self-assembling peptide and nHA/CTS composite scaffolds promote bone regeneration through increasing seed cell adhesion. AB - Porous scaffolds fabricated with nano-hydroxyapatite (nHA) and chitosan (CTS), are widely used in bone tissue engineering (BTE). However, cell adhesion is relatively poor in nHA/CTS scaffolds, which also do not provide an ideal three dimensional environment for seed cells. These deficiencies limit the applicability of these BTE scaffolds to repair bone defects. To address these challenges, we designed a composite scaffold that combines nHA/CTS with self assembling peptide (SAP), a material which is similar to the extracellular matrix. We found that SAP/nHA/CTS scaffolds both increased the adhesion of bone mesenchymal stem cells (BMSCs) and enhanced the mechanical properties of the scaffold. This composite scaffold was then used to repair a femoral condylar bone defect in a mouse model. Healing and mineralization was demonstrated after 12 weeks using H&E staining, microcomputerized tomography, and bone mineral density tests. To our knowledge, this is the first report that SAP/nHA/CTS scaffolds can increase cell adhesion and promote the reconstruction of femoral condylar bone defects. Moreover, this study indicates that BTE using a SAP/nHA/CTS scaffold may be a novel prospective strategy for healing extensive bone defects. PMID- 30274078 TI - Accelerated wound healing and its promoting effects of biomimetic collagen matrices with siderophore loaded gelatin microspheres in tissue engineering. AB - The prolonged inflammation and elevation of Matrix Metalloproteniases (MMPs) at the wound site causes significant degradation of Extracellular matrix (ECM) which cause delays the process of wound healing. Hence the development of therapeutic dressing matrices to control and to positively regulate MMPs balance was considered important in achieving faster healing. The design of biomaterial matrices of collagen scaffold has the challenge to mimic the function of ECM and emulate to the attraction of fibroblast migration at wound site. Herein, we report the fabricated Collagen (COL) matrices impregnated with Siderophore loaded Gelatin Microspheres (SGM) as a delivery system to control both infection and protease levels in the wound site for accelerated healing. The fabricated collagen scaffold impregnated with siderophore loaded gelatin microspheres (COL SGM) was characterized physiochemically using Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and swelling behaviour. The COL-SGM scaffold possesses good swelling ability and also exhibited better morphology for the cell adhesion and proliferation. The in vitro biocompatibility and in vitro fluorescence activity of the developed scaffold revealed to possess good cell proliferation and migration against NIH 3T3 fibroblast and Human keratinocytes (HaCaT) cell lines. Furthermore, the in vivo evaluation offered the advantage of neutralizing the excessive proteases and delivered the siderophore in controlled fashion depending on the level of wound exudates with modulated MMPs. Moreover, the COL-SGM scaffold exhibited with increase in the collagen synthesis and faster reepitheliazation of wounds. Thus the developed COL-SGM scaffold achieved improvements in biocompatibility and act as a potent MMP inhibitor to improve wound healing efficiency in tissue engineering application.

AB - Silver nanoparticles (Ag NPs) serve numerous chief functions in cosmetics, engineering, textile, food technology and medicine. These nanoparticles are also utilized in the pharmaceutical industry particularly in the production of novel antimicrobial agents. However, despite the various studies of Ag NPs induced toxicity, there is a lack of information concerning cellular toxicity mechanisms of these nanoparticles on human cells. In the current project, we investigate the anti-cancer effects of Ag NPs in HepG2 (liver hepatocellular adenocarcinoma) cells. The mean particle size and morphology for the prepared nanoparticles were determined by dynamic light scattering (DLS) and transmission electron microscopy (TEM), respectively. Cell viability, reactive oxygen species (ROS) formation, cytochrome c amount and expression level of BAX/CASP 3/CASP 8/CASP 9 were assayed in HepG2 cells after incubation with Ag NPs. The prepared nanoparticles showed the mean particle size of 30.71 nm with polydispersity index (PDI) of 0.21. Our results revealed decreased cell viability in a concentration-dependent manner and the IC50 of 75 MUg/mL for Ag NPs. Ag NPs cytotoxicity was associated with induction of ROS and cell apoptosis in HepG2 cell line. According to our findings, Ag NPs could be considered as potential chemotherapeutic agents in the treatment of liver hepatocellular carcinoma. PMID- 30274080 TI - Protective nature of low molecular weight chitosan in a chitosan-Amphotericin B nanocomplex - A physicochemical study. AB - Chitosan, a biopolymer of immense potential, has been well-explored over the past decade in the biomedical field. Despite its numerous biological properties like anti-microbial, anti-inflammatory, anti-diabetic etc., limited studies have been conducted on its ability to protect therapeutic molecules in nano-formulations. Amphotericin B (AMP) is one such therapeutic molecule which requires protection as it possesses inherent limitations of poor water-solubility, susceptibility to oxidation- and/or light-induced degradation etc. Although AMP formulations have been quite successful in treating chronic fungal infections, their high cost, prolonged nature of therapy and instability over longer durations has necessitated the development of alternative carriers. In the present study, a stable nanoparticulate formulation was successfully prepared using low molecular weight chitosan and the anti-fungal agent AMP and this was found to offer protection to the labile AMP. The developed nanocomplexes could prevent degradation of AMP up to six months, in solution form, unlike the native drug which degraded in <24 h. Antifungal studies of the developed nanocomplexes revealed a surface charge-dependent antifungal activity. Furthermore, the nanocomplexes did not affect the viability of mammalian cells and showed excellent intracellular uptake and retention, and hence suggested potential of the nanocomplexes in alleviating systemic fungal infections.

AB - : Polyurethane films were obtained in the solvent-free cycloaliphatic polyaddition process of 4,4'-methylenebis(cyclohexyl isocyanate), poly(epsilon caprolactone) diol or poly(oxytetramethylene) glycol and 1,4-butanediol. Chemical structures of the polymers were confirmed by FTIR, NMR and GPC methods. Their surface, thermal and mechanical properties have been evaluated. Results of biological studies with polyurethane films as potential biomaterials for medical applications revealed their mild cytotoxicity against normal human fibroblasts (BJ) and immortalized keratinocytes (HaCaT). STATEMENT OF SIGNIFICANCE: The research is relevant for the potential uses of polyurethane films made from commercial raw materials as general medical supplies. PMID- 30274082 TI - Copper-polyaniline nanocomposite: Role of physicochemical properties on the antimicrobial activity and genotoxicity evaluation. AB - Copper nanoparticles (Cu NPs) have proven to own excellent antimicrobial efficacy, but the problems of easy oxidation and aggregation limit their practical application. Here, nanocomposite based on polyaniline (PANI) and Cu NPs solved this problem and brought additional physicochemical properties that are markedly advantageous for antimicrobial applications. Current work exploits this potential, to examine its time- and concentration-dependent antimicrobial activity, employing E. coli, S. aureus, and C. albicans as a model microbial species. Regarding the presence of polaronic charge carriers in the fibrous polyaniline network, effects of Cu NPs' size and their partially oxidized surfaces (the data were confirmed by HRTEM, FESEM, XRD, Raman and XPS analysis), as well as rapid copper ions release, Cu-PANI nanocomposite showed efficient bactericidal and fungicidal activities at the concentrations <=1 ppm, within the incubation time of 2 h. Beside the quantitative analysis, the high levels of cellular disruption for all tested microbes were evidenced by atomic force microscopy. Moreover, the minimum inhibitory and bactericidal concentrations of the Cu-PANI nanocomposite were lower than those reported for other nanocomposites. Using such low concentrations is recognized as a good way to avoid its toxicity toward the environment. For this purpose, Cu-PANI nanocomposite is tested for its genotoxicity and influence on the oxidative status of the human cells in vitro. PMID- 30274083 TI - Effect of annealing temperature on mechanical and antibacterial properties of Cu bearing titanium alloy and its preliminary study of antibacterial mechanism. AB - Cu-bearing titanium alloys are designed and studied as a novel medical metal material with antibacterial function. However, the addition of Cu would affect the mechanical properties of titanium alloy more or less, especially the ductility, despite its excellent antibacterial property. Thus, the aim of this study was to optimize the heat treatment for Cu-bearing titanium alloys in order to achieve a balance of satisfactory mechanical, antibacterial and other properties. In this study, Ti6Al4V-5 wt% Cu alloy was fabricated, and then different annealing treatments with various heating temperatures (700-910 degrees C) were employed on the alloy. The effects of heating temperature on microstructure evolution, mechanical properties, corrosion resistance and antibacterial performance of Ti6Al4V-5Cu alloy were systematically studied. It was found that annealing at 740 degrees C for Ti6Al4V-5Cu alloy showed the best comprehensive properties of high strength, excellent ductility, corrosion resistance and antibacterial performance. The Ti2Cu phases played an important role in the mechanical property and antibacterial performance for Ti6Al4V-5Cu alloy, and bacteria preferred to adhere on the alpha phase region, rather than the beta or globule Ti2Cu region. PMID- 30274085 TI - Towards rational design of porous nanostructured biopolymeric microparticles for biomacromolecules separation: A case study of intraparticle diffusion facilitation and BSA adsorption on agarose microspheres. AB - Synthesis and employing advanced materials for emerging applications is of great challenge for the scientific community. Recombinant proteins production and purification is one of the fastest growing fields in the global economy. In this regard, it is essential to fabricate biocompatible low-cost materials with high specificity to enhance purification efficiency. This requires the regulation of mass transfer based on the protein molecular size and interactions with the matrix interface; thus, needs synthesizing novel materials with tuned porosity. In this study, we proposed rational alteration in porous structure of biopolymeric microspheres using appropriate-sized porogen to facilitate intraparticle molecular diffusion. The tailored porous nanostructures, which were generated by phase separation in the polymer blend of agarose and polyethylene glycol, were analyzed with optical and scanning electron microscopy, Fourier transform infrared spectroscopy, water diffusion, and albumin adsorption. The well-tuned beads possessed highly porous structures with dominant mesopores owing to PEG phase migration out of the network. The high speed homogenizer caused an uncommon dense morphology with interwoven two-type porosity. Optimally tuned mesoporous beads with considerably high specific surface area exhibited dramatically fast and enhanced intraparticle diffusion of both water and protein molecules. Thus, the introduced porosity modification is a promising design for enhancing mass transfer in the bio-separation process. Finally, useful insights for developing future smart hydrogel microparticles with tuned porous network for biomolecules purification are provided by the conducted experiments.

AB - The application of pristine S60 fullerene aqueous colloid solution (C60FAS; 0.5 mg/kg body weight) for rats experienced acute colitis, either intraperitoneally or intrarectally (1) restores the colonic mucosa healing and epithelial barrier integrity, evidenced by autopsies and histological findings and the normalization of phenolsufonphthalein dye daily excretion; (2) attenuates the consequences of hemorrhages, such as signs of anemia and increased platelet count; (3) improves the liver redox status suppressing the lipid peroxidation (malonic dialdehyde and protein carbonyl group levels tended down) and stimulating the antioxidant defense system (glutathione peroxidase activity grew up). In addition, C60FAS intrarectally increases the monocyte count and decreases content of neutrophil granulocytes, i.e. diminishes the rate of the inflammatory process and activates the processes of colon tissues restoring with monocytes involvement. Therefore, intrarectal administration of C60FAS may serve as an efficient tool of ulcerative colitis therapy. PMID- 30274086 TI - Release mechanisms of urinary tract antibiotics when mixed with bioabsorbable polyesters. AB - In depth knowledge of the thermal properties of drugs is particularly important when they are designed for incorporation into a thermoplastic polymer matrix. In this paper a representative set of Urinary Tract Infection (UTI) antibiotics were studied using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), and then blended via solvent-casting method with poly(D,L lactide-co-epsilon-caprolactone). Of these, amoxicillin, cefdinir, levofloxacin and norfloxacin showed a co-continuous morphology with the polyester, whereas blends with ciprofloxacin, nitrofurantoin and tobramycin resulted in two immiscible phases. E. coli susceptibility results showed that the activity of these antibiotics was not affected by the interactions with the polymer matrix. The presence of the drug did not change the hydrolytic degradation kinetics of this fully amorphous polyester (KMw of ~0.050 days-1). However, the release profiles from the long-term studies (105 days) with a 10 or 30% of antibiotic loaded films were quite different. While water was able to penetrate the polymer matrix and elute the entire levofloxacin content in the first 8 h, the burst release of cefdinir reached a value under 75%. A more interesting profile was obtained with nitrofurantoin, suggesting that a lengthy treatment is achievable. <30% of the drug was burst released, ~55% eluted by diffusion up to day 42 and the rest driven by the weight loss of the bioabsorbable polyester. PMID- 30274087 TI - Evaluation of the corrosion inhibiting efficacy of a newly synthesized nitrone against St37 steel corrosion in acidic medium: Experimental and theoretical approaches. AB - A novel amphiphilic nitrone, N-phenyl-1-(4-((11-(pyridin-1-ium-1yl) undecanoyl) oxy)phenyl)methanimine oxide bromide (NP-1-4-11-PUOPMOB) has been synthesized from a fatty acid derivative as a starting material. Structural characterization of the new compound has been realized by spectroscopic techniques (FTIR, 1H NMR, and 13C NMR). The corrosion inhibition effect of the compound for St37 steel corrosion in 1 M HCl medium has been investigated using experimental (weight loss, electrochemical impedance spectroscopy, potentiodynamic polarization, dynamic electrochemical impedance spectroscopy) and theoretical approaches complemented by surface morphological examination using energy dispersive X-ray spectroscopy, scanning electron microscope, and atomic force spectroscopy. Results from both chemical and electrochemical techniques reveal that the presence of the nitrone in the acid solution impedes St37 steel corrosion. The inhibition efficiency obtained at 125 ppm and 150 ppm concentrations for all methods is found to be over 90%. NP-1-4-11-PUOPMOB behaves as a mixed type corrosion inhibitor according to the potentiodynamic polarization studies. The adsorption of NP-1-4-11-PUOPMOB molecules onto the metal surface follows Langmuir adsorption isotherm and the calculated Kads (equilibrium constant of the adsorption process) value reflects strong interaction. There is evidence of NP-1 4-11-PUOPMOB adsorption on the metal surface from SEM, EDAX, and AFM studies. Experimental and theoretical results are in good agreement. PMID- 30274088 TI - Y-shaped copolymers of poly(ethylene glycol)-poly(epsilon-caprolactone) with ketal bond as the branchpoint for drug delivery. AB - In this study, a Y-shaped amphiphilic block copolymer consisting of hydrophilic poly(ethylene glycol) (mPEG) and two poly(epsilon-caprolactone) (PCL) as the hydrophobic arms with a ketal linker was synthesized (mPEG-Ketal-(PCL)2). The structure of the copolymer with different compositions was characterized by 1H NMR, gel permeation chromatography (GPC) and differential scanning calorimetry (DSC). The amphiphilic property endows the copolymer with the ability to be self assembled into micelles for encapsulating anticancer drug doxorubicin (DOX), and the effect of copolymer with different PCL length on drug loading properties were tested. The morphology, size, pH responsiveness, drug release profile and in vitro anticancer activity of the DOX loaded micelles were also studied. In vitro drug release studies showed that over 50% of the DOX was released at pH 5.0 in 24 h because of hydrolysis of ketal linker in the copolymers. The confocal laser microscopy and flow cytometry experiments showed that the DOX-loaded micelles could be effectively internalized by Hela cells, the ketal bond in the backbone was broken in acid endo/lysosomal compartments and triggered the fast release of DOX. The in vitro antitumor efficacy of the DOX loaded mPEG-Ketal-(PCL)2 micelles was better than that of non-pH sensitive ones. In vivo studies showed that the mPEG-Ketal-(PCL)2 micelles enhanced the DOX blood circulation time and had good tumor-targeting efficiency. PMID- 30274089 TI - Corrosion and biological performance of biodegradable magnesium alloys mediated by low copper addition and processing. AB - Mg-Cu alloys were designed by introducing the well-known antibacterial property of copper into magnesium alloy to solve the infection problem especially under the neutralised environment in vitro. In this paper, the Mg-Cu alloys with further processing by solution and extrusion were studied to optimise the corrosion-related performance for their future application. It was shown that the differences in the property profile of Mg-Cu alloys are dependent on different compositions as well as on different microstructures that are obtained by the different processing routes. Galvanic corrosion can be significantly relieved by solution treatment and extrusion due to decrease and well distribution of cathodic Mg2Cu phases. Negligible cytotoxicity were observed with rBMSCs incubation. Antibacterial assays proved that the alloys reduced the viability of Staphylococcus aureus by high alkalinity and copper ions releasing, especially in comparison with pure magnesium. Finally, the as-solutionized Mg-0.1Cu alloy showed the optimal corrosion properties and promising antibacterial activity, which warranted its potentials as antibacterial biodegradable implant materials. PMID- 30274090 TI - Effect of UV radiation and chitosan coating on the adsorption-photocatalytic activity of TiO2 particles. AB - The effect of chitosan, pH and UV-VIS radiation on the adsorption-photocatalytic properties of TiO2 dispersion was investigated on the basis of electrophoretic mobility, as well as spectrophotometric and dynamic light scattering measurements. For the degradation efficiency tests two different dyes: the cationic - methylene blue and the anionic - sunset yellow were used. The stability and photodegradation experiments were performed by varying the parameters: wavelength of light (range 450-750 nm), type and radiation time (UV and VIS; 0-5 h), pH (3 and 6) and pigment concentration (0.6 * 10-5-3.6 * 10-5 mol/dm3). In the chitosan-modified dispersions polysaccharide exhibits synergism of adsorption-photocatalytic properties of TiO2. Chitosan increases the biodegradability of the chitosan/TiO2 composite and additionally, it can be potentially used as a promising anti-microbial material. PMID- 30274091 TI - Towards wound dressings with improved properties: Effects of poly(dimethylsiloxane) on chitosan-alginate films loaded with thymol and beta carotene. AB - This study aimed to evaluate the effect of poly(dimethylsiloxane) on the mechanical properties of chitosan-alginate (CA) polyelectrolyte complexes (PECs) with potential application as wound dressing biomaterials. For that purpose, different amounts of poly(dimethylsiloxane) were incorporated during the formulation of the PECs. Results showed that the highest tensile strength was observed when using 0.1 g of poly(dimethylsiloxane) per gram of PEC (CAS10). This formulation was also non-hemolytic, capable of inducing thrombus formation to potentially reduce bleeding, and additionally presented high stability when exposed to physiological fluids and/or conditions simulating patient bathing. To improve its wound healing capacity, this formulation was loaded with thymol and beta-carotene (anesthetic, anti-inflammatory and antioxidant compounds) by the supercritical carbon dioxide impregnation/deposition (SSI/D) method at 250 bar and 45 degrees C for 14 h and at two depressurization rates (5 and 10 bar/min). The PECs were also loaded by conventional impregnation in solution for comparison purposes. Higher bioactive loadings, of 1.8 +/- 0.2 and 1.3 +/- 0.03 MUg per milligram of PEC for thymol and beta-carotene, respectively, were observed when using SSI/D and a higher depressurization rate (10 bar/min). These values do not correspond to the maximum loaded amount of each bioactive, which were strongly retained in the PEC structure due to favorable bioactive-polymer interactions, originating matrices that should present a more sustained release during in vivo applications. PMID- 30274092 TI - Composite material based on hydroxyapatite and multi-walled carbon nanotubes filled by iron: Preparation, properties and drug release ability. AB - The novel bioactive composite material based on hydroxyapatite and multi-walled carbon nanotubes filled by iron was synthesized by the "wet chemistry" method and characterized in detail by various experimental techniques including the X-ray diffraction, Fourier transform infrared and energy-dispersive X-ray fluorescence spectroscopy, thermogravimetric and differential thermal analysis. The swelling behaviour was quantified by measuring the changes in sample weight as a function of sample immersion time in a phosphate buffered saline (PBS). Bioactivity test was carried out by soaking the samples in PBS. The material composition influence on the model drug release was studied using the high-performance liquid chromatography method. Finally, the mechanical properties (maximal relative deformation, strength and Young's modulus) of the samples under loading were investigated too. The findings clear demonstrate the possibility of application of the created composite material in bioengineering of bone tissue to fill bone defects of various geometries with the function of prolonged release of the drug. It is assumed that this composite material can be used in 3D modeling of areas of bone tissue that have to bear a mechanical load. PMID- 30274093 TI - Vascular extracellular matrix and fibroblasts-coculture directed differentiation of human mesenchymal stem cells toward smooth muscle-like cells for vascular tissue engineering. AB - Construction of an artificial vascular graft is widely considered a promising strategy in vascular tissue engineering. However, limited sources of functional vascular smooth muscle cells (VSMCs) remain a major obstacle in vascular tissue engineering. In this study, we innovatively developed an approach to obtain functional VSMCs by onsite differentiating human bone marrow-derived mesenchymal stem cells (MSCs) directed by decellularized extracellular matrix (ECM) and fibroblasts. The resulting cells and ECM-cells constructs were characterized by real time RT-PCR, immunofluorescence staining, cell contractile functions, and migration capacity. Our results showed both ECM and fibroblasts induced MSCs differentiation toward VSMC-like cells with increased transcription of marker genes, upregulated expression of contractile apparatus proteins, and enhanced functional activity of VSMC phenotype. Interestingly, our findings revealed that native ECM and fibroblasts-coculture had a higher potential to promote MSCs differentiation into VSMCs than growth factors cocktail (GFC) supplemented culture, thereby providing a potential source of VSMCs for blood vessel constitution. PMID- 30274094 TI - Evaluation and efficacy of metal oxides in terms of antibacterial activity and toxic chemical degradation. AB - Inorganic metal oxides Ag2O, CuO and ZnO were examined using SEM, XRD, TGA and ICP spectroscopy to analyze their structures and physical properties in terms of resistance to germs and toxic chemicals. Zone of inhibition testing and the plate counting method were used in this study to examine the antibacterial activities of the metal oxides against Gram-negative Escherichia coli (E. coli) and Pseudomonas aeruginosa (P. aeruginosa), and Gram-positive Staphylococcus aureus (S. aureus) and Bacillus subtilis (B. subtilis). Furthermore, 2-chloro-ethyl ethyl sulfide (2-CEES) was used to study the degradation efficacy of the metal oxides by the NMR method. The objective of the study was to develop and evaluate metal oxides that are able to protect against chemical and biological warfare agents. Excellent antibacterial and catalytic toxic chemical degradation properties were obtained. PMID- 30274095 TI - Catalytic reduction of p-nitrophenol and methylene blue by microbiologically synthesized silver nanoparticles. AB - Catalytic Reduction of p-nitrophenol and Methylene blue by Microbiologically Synthesized Silver Nanoparticles was studied in the present investigation. Catalytic reduction of 4-Nitophenol/p-nitrophenol (PNP) and methylene blue (MB) was assessed using both intra and extracellular silver nanoparticles (AgNP) with and without immobilization. Both intracellular and extracellular AgNP were synthesized from actinomycetes. Antimicrobial activity of AgNP was also assessed and it was found that, intracellular AgNP have significant antibacterial activity against E. coli, S. typhi and B. subtilis. Synthesized biogenic silver nanoparticles were characterized by UV-visible spectrophotometry, FTIR, XRD, and TEM-EDS. It was found that, extracellular AgNP are efficient as compared to intracellular AgNP in terms of PNP reduction. PMID- 30274096 TI - The effect of human-like collagen calcium complex on osteoporosis mice. AB - The objective of this study was to assess the effect of a modified human-like collagen calcium complex on osteoporosis mice. BHK (Baby Hamster Kidney) cells were used to compare the cytotoxicity of different calcium reagents with the MTT test. Six-week-old male mice (n = 80) were randomly divided into eight groups: a blank group (blank), control group (control), human-like collagen calcium group (HLC-Ca), thiolated human-like collagen calcium group (SH-HLC-Ca), phosphorylated human-like collagen calcium group (Pi-HLC-Ca), gluconate group (Glc-Ca), calcium carbonate group (CaCO3) and D-cal group (B). A systematic analysis of the results available in vivo after 3 months of treatment was presented. The effects of several Ca supplements on osteoporosis mice were investigated by detecting serum calcium, alkaline phosphate activity (ALP), bone hydroxyproline (BHP) and bone mineral density (BMD). The results proved that the BMD and BHP of osteoporosis mice were significantly increased in the Pi-HLC-Ca group, while serum calcium and ALP were decreased. Therefore, Pi-HLC-Ca is likely a good calcium supplement for clinical applications. In this review, the advantage of Pi-HLC-Ca in preventing and delaying osteoporosis is highlighted. In addition to the current progress, further investigations are necessary to reveal the relative influences of collagen and calcium proportions on the long-term clinical effects of osteoporosis. PMID- 30274097 TI - Novel methods for the mechanical characterization of patches used in carotid artery repair. AB - Carotid endarterectomy (CEA) is one of the approaches available for the treatment of carotid artery disease, with carotid patch angioplasty the pertinent technique mostly preferred by vascular surgeons. This technique entails an arteriotomy succeeded by closure with a textile, polymer or biological tissue patch. In this work, we propose microbuckling and microindentation as novel methodologies for acquiring the mechanical properties of patches used in carotid artery repair. Regarding microbuckling, the patch is loaded by a sensitive dynamometer at one end and its motion is recorded, at three different levels of axial deformation: delta/l = 0.1, 0.3 and 0.5 (in the post-buckling regime). The corresponding experimental loads are recorded, as well. Following pertinent closed-from equations, various material metrics are obtained, such as the Young's modulus of elasticity and the so-called frictional couple of the material. Regarding microindentation, the material's hardness number is measured with the aid of a durometer. Similar to microbuckling, indentation analytical expressions allow for the determination of key material properties, such as the modulus of elasticity, indentation forces and depths. Where possible, we perform microtension to verify acquired results. Results demonstrate that measured properties may vary substantially for materials which are of the same type, due to variations of the material microstructure, as observed with optical and scanning electron microscopes (SEM). Several commercial patches were tested in this work. To shortly present the main results, the microbuckling technique furnished (for the Young's modulus) 40.17 MPa for the B/Braun Aesculap cardiovascular patch and 71.49 MPa for the Vasutek Terumo, while the microindentation technique, for bovine patches, provided 6.356 MPa for the Xeno Sure and 4.701 MPa for the Vascu Guard. A test type recommendation is provided, relating the type of the patch material to the method more plausible in each case, in order to achieve better measurement accuracy. Results of this study can contribute in establishing guidelines and criteria determining material selection in CEA. PMID- 30274098 TI - Acute toxicity and biodistribution of different sized copper nano-particles in rats after oral administration. AB - In order to compare the detailed toxicity of nano-copper and CuCl2.2H2O (Cu ions) in vivo, the oral toxicity of four differently sized Cu particles (30 nm, 50 nm, 80 nm and 1 MUm) on rats was investigated compared with CuCl2.2H2O in acute exposure scenarios. We compared the acute LD50 values and evaluated the kinetics of Cu following a single equivalent dose (200 mg/kg) of five Cu materials. Continuous gavage of nano-copper for 7 days, the mortality rates, relative organ weights, and hematological, biochemical, and histopathologic characteristics of rats were examined. The results showed that the LD50 values of Cu ions, 30 nm, 50 nm, 80 nm, and 1 MUm copper particles were 359.6, 1022, 1750, 2075, and >5000 mg/kg, respectively. Physiological and biochemical indexes indicated that 80 nm nano-copper (Cu NPs) produced the highest degrees of toxicity in short term. The liver and kidneys were the major organs most affected by Cu NPs, and also the target organs for Cu accumulation. The toxic effects of Cu ions are similar to those of nano-copper, but they were not the same. Therefore, the toxic effect of nano-copper is likely to be the result of the dual action of nano-copper particles and copper ions. Collectively, the acute toxic effects produced by Cu NPs were highly correlated with particle size. Moreover, the toxic effects produced by repeated dosing differed from those produced by a single dose, and this may be due to organ targeting effects that are dependent on the size of the nano-particles. PMID- 30274099 TI - Phytosynthesis of gold nanoparticles: Characterization, biocompatibility, and evaluation of its osteoinductive potential for application in implant dentistry. AB - Gold nanoparticles have been extensively used in diagnostics, biomedical imaging, and drug delivery owing to simple method of synthesis and versatile surface functionalization. Present investigation aims to evaluate the osteoinductive property of Salacia chinensis (SC) mediated gold nanoparticles (GNPs) for its application in implant dentistry. The formation of GNPs was assessed initially using the visual method and characterized analytically by using UV-visible spectroscopy, Zetasizer, X-RD, ICP-AES, AFM, and TEM. Green synthesized GNPs exhibited a remarkable stability in various blood components (0.2 M histidine, 0.2 M cysteine 2% bovine serum albumin, and 2% human serum albumin) and were found to be nontoxic when evaluated for their cytocompatibility and blood compatibility using periodontal fibroblasts and erythrocytes respectively. Exposure of GNPs to MG-63 cell lines displayed increased percent cell viability (138 +/- 27.4) compared to the control group (96 +/- 3.7) which confirms its osteoinductive potential. Herein, it can be concluded that the stable, biocompatible and eco-friendly GNPs can be used as an effective bone inductive agent during dental implant therapy. PMID- 30274100 TI - Influence of the incorporation of the antimicrobial agent polyhexamethylene biguanide on the properties of dense and porous chitosan-alginate membranes. AB - This work is a continuation of a previous study which described the development of dense and porous chitosan-alginate polyelectrolyte complexes through the addition of different amounts of Pluronic F68 to the polymeric mixture. The present study consisted in the incorporation of an antimicrobial agent, polyhexamethylene biguanide (PHMB), to the previously developed system. PHMB was incorporated at 1 and 10% (w/w) with high incorporation efficiencies, varying from 72 to 86%. Release profiles in phosphate buffered saline were evaluated using the Korsmeyer-Peppas equation, which suggested a quasi-Fickian diffusion mechanism for all obtained formulations. The maximum release percentage was approximately 15% as a result from the high affinity between PHMB and the polysaccharides. The obtained polyelectrolyte complexes were able to prevent the growth of both Staphylococcus aureus and Pseudomonas aeruginosa on their surfaces, being considered potentially effective wound dressings. PMID- 30274101 TI - One-pot ultrafast preparation of silica quantum dots and their utilization for fabrication of luminescent mesoporous silica nanoparticles. AB - Silica quantum dots (SiQDs) and their luminescent composites have displayed great potential for biomedical applications owing to their chemical inert and low cost. In this work, we report a facile, cost-effective and ultrafast strategy to prepare a stable luminescent SiQDs using N-[3 (trimethoxysilyl)propyl]ethylenediamine (EDAS) and salicylaldehyde as precursors for the first time. These luminescent SiQDs were further utilized for fabrication of luminescent mesoporous silica nanoparticles (MSNs) through direct encapsulation of SiQDs by MSNs. The novel synthetic and modified SiQDs uses commercial raw materials and the entire reaction can be completed within 30 s. The successful preparation of SiQDs and SiQDs@MSNs were characterized by various characterization equipments. The cell viability as well as cell uptake behavior of SiQDs@MSNs were also examined to evaluate their potential for biomedical applications. We demonstrated that these SiQDs@MSNs are low toxicity and of great potential for biological imaging. Based on the above results, we believe that these SiQDs@MSNs should be novel and promising candidates for biomedical applications owing to their intense fluorescence, biocompatibility and high specific surface areas. PMID- 30274102 TI - Nanotopographical cues of electrospun PLLA efficiently modulate non-coding RNA network to osteogenic differentiation of mesenchymal stem cells during BMP signaling pathway. AB - Application of stem cells in combination with nanofibrous substrates is an interesting biomimetic approach for enhanced regeneration of damaged tissues such as bone and cartilage. The investigation of the complex interplay between nanotopographical cues of niche and noncoding RNAs in stem cells fate is an effective tool to find a new strategy for enhancing the induction of osteogenesis. In this study, we investigated the effects of aligned and random orientations of nanofibers as a natural ECM-mimicking environment on the network of noncoding RNA in mesenchymal stem cells. Aligned and randomly oriented Ploy (L lactide) PLLA scaffolds were fabricated via electrospinning. Human Adipose Tissue Derived Mesenchymal Stem Cells (hASCs) were isolated from adipose tissue and were cultured on surfaces of these scaffolds. Their capacity to support hMSCs proliferation was also investigated by MTT assay and the expression of c-Myc gene. Then, after 7, 14 and 21 days, the osteogenic commitment of hMSCs and the miRNA regulatory network in BMP signaling pathway were evaluated by measuring alkaline phosphatase (ALP) activity, extracellular calcium deposition, and bone related gene activation by Real-Time PCR. Furthermore, osteogenic differentiation was evaluated with regard to their noncoding RNA network. Our results for the first time showed an interaction between nanotopographical cues and miRNA activity in hMSCs. We found that the nanotopographical cues could be used to influence the osteogenic differentiation process of hMSCs through the modulation of lncRNAs and miR-125b as negative regulators of osteogenesis as well as the H19 modulator BMP signaling pathway that acts as a miRNA sponge. Moreover, we also demonstrated for the first time that MEG3 as a long noncoding RNA is controlled by miR-125b and microRNA-triggered lncRNA decay mechanism. This strategy seems to be an important tool for controlling stem cell fate in engineered tissues and provide new insights into most biocompatible scaffolds for bone-graft substitutes.

AB - With increasing demand for novel and potent antimicrobial agents to combat cross infections and infectious diseases, silver and copper based nanoparticles (NPs) deposited over supports such as montmorillonite (MMT) are playing a crucial role in shaping the current research scenario. Although materials based on Ag NP and Cu NP on MMT have been reported, its toxicological properties on human cell lines have not been accounted for. This paper reports a comparative study on synthesis, antibacterial, antifungal and toxicological behavior of Ag and Cu NPs deposited over MMT nanosheets synthesized by employment of different reduction media. The effect of synthesized NP-MMT hybrids on human erythrocytes and fibroblast cells has been evaluated. The NP formation was facilitated using borohydride and ethyl alcohol (wet chemical route) and photo-reduction and thermal treatment (physical reduction route). The NP-MMT hybrids showed NP formation over supporting silicate layers with particle size ~10-50 nm confirmed by TEM micrographs and loading of ~6-22 wt% of metallic element by EDX analysis. The MMT layers were peeled apart to accommodate NPs inside its galleries, confirmed by increased d-value in powder WAXD. The NP-hybrids showed excellent inhibition zone against bacteria E.coli and S. aureus and fungi A. niger. RBC hemolysis and cytocompatibility assay were performed in vitro to advocate its safety to live human cells. These hybrid materials are potential candidates for new generation advanced antimicrobial materials with less toxicity and highly potent behavior.

AB - Capsaicin (CAP) is a secondary metabolite with high therapeutic potential. It displays several bioactive properties including hypolipidemic, antioxidant, anti inflammatory and analgesic effects. However, CAP presents toxicity to healthy cells and poor pharmacokinetic profile, which is characterized by toxic metabolites and short half-life. In this study, CAP-loaded albumin nanoparticles were obtained by the desolvation-coacervation method. The preparation process was optimized by the application of a factorial design. Nanoparticles presented diameter of about 200 nm, quasi-spherical morphology, encapsulation efficiency of 98.3 +/- 7.4%, and negative zeta potential. The in vitro release assay demonstrated a biphasic profile, characterized by a fast release over 12 h followed by a prolonged release rate. Nanoencapsulated CAP showed significant antioxidant activity in an in vitro assay which was concentration - and time dependent. In addition, the in vivo study demonstrated for the first time that both free and nanoencapsulated drug reduced TNF-alpha concentrations in the absence of inflammatory stimuli model. These novel findings indicate that albumin nanoparticles are potential CAP carriers and that this new drug formulation may be useful in several conditions, including cancer, inflammation, and neuropathic pain.

AB - Based on the self-assembly properties of vapreotide acetate (Vap), one kind of novel vapreotide acetate-gold nanoflowers (Vap-AuNFs) was fabricated for the first time by biomimetic mineralization method using Vap as a template. The Vap AuNFs possessed anisotropic structure with a large absorption cross-section, which were face-centered cubic crystalline, exhibiting a remarkable monodisperse, narrow size (154 nm) distribution and good stability in aqueous solution. The apparent anisotropy of the gold nanostructure with high molar extinction coefficient can cause significantly higher plasmon absorption of Vap-AuNFs in the near infrared (NIR) region compared with Au nanoparticles (AuNPs), so the nanocomplex can induce remarkably enhanced photothermal conversion efficiency under NIR light irradiation. Breathtakingly, Vap-AuNFs exhibited superior biocompatibilities compared to AuNPs, as well as enhanced Hela cells lethality under NIR irradiation. This novel method was simple, low cost and green for the design and preparation of anisotropic gold nanoflowers with outstanding NIR laser induced local hyperthermia, highlighting their potential applications in biomedical fields. PMID- 30274106 TI - Controlled degradability of PCL-ZnO nanofibrous scaffolds for bone tissue engineering and their antibacterial activity. AB - Up to date, tissue regeneration of large bone defects is a clinical challenge under exhaustive study. Nowadays, the most common clinical solutions concerning bone regeneration involve systems based on human or bovine tissues, which suffer from drawbacks like antigenicity, complex processing, low osteoinductivity, rapid resorption and minimal acceleration of tissue regeneration. This work thus addresses the development of nanofibrous synthetic scaffolds of polycaprolactone (PCL) - a long-term degradation polyester - compounded with hydroxyapatite (HA) and variable concentrations of ZnO as alternative solutions for accelerated bone tissue regeneration in applications requiring mid- and long-term resorption. In vitro cell response of human fetal osteoblasts as well as antibacterial activity against Staphylococcus aureus of PCL:HA:ZnO and PCL:ZnO scaffolds were here evaluated. Furthermore, the effect of ZnO nanostructures at different concentrations on in vitro degradation of PCL electrospun scaffolds was analyzed. The results proved that higher concentrations ZnO may induce early mineralization, as indicated by high alkaline phosphatase activity levels, cell proliferation assays and positive Alizarin-Red-S-stained calcium deposits. Moreover, all PCL:ZnO scaffolds particularly showed antibacterial activity against S. aureus which may be attributed to release of Zn2+ ions. Additionally, results here obtained showed a variable PCL degradation rate as a function of ZnO concentration. Therefore, this work suggests that our PCL:ZnO scaffolds may be promising and competitive short-, mid- and long-term resorption systems against current clinical solutions for bone tissue regeneration.

AB - Dopamine (DA) is an important catecholamine neurotransmitter in the mammalian central nervous system, and is involved in many behavioral responses and brain functions, and thus the detection of DA is much important. Chiral nanoparticles (NPs) have aroused much attention and showed many potential applications. In this work, Chiral ZnO NPs was prepared, and the nanoparticles can disperse well without aggregation. The Circular dichroism (CD) test showed strong chiroptical signals, demonstrating it is an effect method to prepare Chiral ZnO with cysteine as ligand. The photoluminescent properties of Chiral ZnO was investigated and showed quenching effect to dopamine, which make it possible to be used as probes to detect dopamine in biological samples with high selectivity and sensitivity. PMID- 30274108 TI - Phytosynthesis of gold and silver nanoparticles enhance in vitro antioxidant and mitostimulatory activity of Aconitum toxicum Reichenb. rhizomes alcoholic extracts. AB - Extracts obtained from different plant species proved to be a valuable tool in various biomedical applications. In the same time, the phytosynthesis of noble metal nanoparticles represents an already well-established route for obtaining nanoparticles with biological activity. The present paper studies the antioxidant activity and the cytogenetic effects of the alcoholic extracts from rhizomes of Aconitum toxicum Rchb., before and after the phytosynthesis of gold and silver nanoparticles, on the meristematic root cells of Allium cepa L., and on the general mitotic index and the progression rate through the mitotic phases, respectively, as well as on the genetic material organized in chromosomes. The extracts were characterized in terms of total polyphenolics content (1.49% and, respectively, 2.29%) and aconitine content (by HPLC - 4.891 mg/L and, respectively, 18.211 mg/L), while the phytosynthesis of metallic nanoparticles was monitored by UV-Vis spectrometry, X-ray diffraction, X-ray fluorescence and electron microscopy. Both the extracts and the obtained nanoparticles were evaluated for antioxidant potential (the antioxidant activity ranging between 78% and 84.32%) and cytogenetic effects. The obtained results prove the phytosynthesis of AgNPs and AuNPs with dimensions ranging from 9 nm to 15 nm for AuNPs, respectively from 53 nm to 67 nm for AgNPs. The extracts obtained from rhizomes of A. toxicum Rchb. induced mitotic stress, as well as a series of nuclear and mitotic aberrations. The biosynthesis of AgNPs and AuNPs intensified the antioxidant and mitostimulatory activity of the extracts. PMID- 30274109 TI - Hydroxide assisted synthesis of monodisperse and biocompatible gold nanoparticles with dextran. AB - A simple and rapid approach to synthesize monodisperse and biocompatible gold nanoparticles (AuNPs) employing dextran as a reducing and stabilizing agents at different reaction conditions was described. The obtained dextran-gold nanoparticles (Dex-AuNPs) were characterized by transmission electron microscopy (TEM), UV-Vis spectroscopy, Nuclear magnetic resonance (NMR) spectroscopy, Fourier transformer infrared (FTIR) spectroscopy and X-ray diffraction (XRD) analysis. The TEM examinations showed the resultant particles were 4-50 nm in size, monodispersity and uniform particle size distribution. Moreover, the size of the nanoparticles can be controlled by varying the concentration of the reactants. UV-Vis spectra showed that the characteristic localized surface plasmon resonance (LSPR) band of AuNPs was at about 525 nm. NMR spectroscopy and FTIR spectroscopic analysis suggested the detailed structural information of dextran before and after synthesis of AuNPs. XRD and selected area electron diffraction (SAED) pattern analysis demonstrated that the colloidal nanoparticles had a well crystallized structure. The experimental analyses revealed that NaOH played an important role in the synthesis of Dex-AuNPs. And the possible formation mechanism of the fabrication of these Dex-AuNPs was also proposed. MTT assay was utilized to evaluate the cytotoxicity of the synthesized Dex-AuNPs on HeLa cells and SiHa cells. These results suggested that the prepared Dex-AuNPs complexes had excellent biocompatibility and acted as a candidate for further biomedical application. PMID- 30274110 TI - Ultrasound assisted reverse micelle efficient synthesis of new Ta-MOF@ Fe3O4 core/shell nanostructures as a novel candidate for lipase immobilization. AB - In the present study, Ta-MOF@Fe3O4 core/shell nanostructures were synthesized in optimal conditions using the rapid, efficient, and novel ultrasound assisted reverse micelle method. FTIR, TGA/DTG, XRD, TEM, EDS and N2 adsorption/desorption isotherms were conducted in order to obtain samples with desirable properties. Results showed that the synthesized products had the thermal stability of 200 degrees C, particle-size distribution of 38 nm and surface area of 740 m2/g. Also, the VSM test showed that these compounds have desirable magnetic properties which provide the opportunity for recovery. Based on these obtained properties, final products were used as a novel candidate for enzyme immobilization. Results of SEM images revealed that the Bacillus licheniformis Km12 lipase is efficiently loaded on the Ta-MOF@Fe3O4 core/shell substrate. The stability test indicated the high stability of the enzyme loaded into these nanostructures. The synthesis method and the results obtained from enzyme immobilization developed in this study can be a new strategy for various applications of these novel compounds in diverse biological fields. PMID- 30274111 TI - Self-assembly of sugar based glyco-lipids: Gelation studies of partially protected d-glucose derivatives. AB - A series of sugar-based glycolipid derivatives were prepared by N-glycosylamines, and their organogelation property has been analyzed. We have observed the efficient gelation for some of the anilines substituted glycolipids derivatives in different aromatic and aliphatic solvents. It was found that the gelation occurred predominantly in aliphatic solvents with CGC of 0.8% (w/v) attributed to the presence of long alkyl chain in the glycolipids. The structural and morphological properties of the xerogels were investigated by NMR, powder XRD, and FE-SEM respectively. Furthermore, the thermal stability was analyzed by DSC. PMID- 30274112 TI - A novel cysteine-linked antibacterial surface coating significantly inhibits bacterial colonization of nasal silicone prongs in a phase one pre-clinical trial. AB - Ventilator associated pneumonia and sepsis are frequent complications in neonatal care. Bacterial colonization of medical devices and interfaces used for respiratory support may contribute by functioning as a bacterial reservoir seeding bacteria into airways. We have developed an antibacterial surface coating based on a cysteine ligand covalently coupled via a spacer to a carboxylic backbone layer on an acrylic acid grafted silicone surface. This coating was applied on a commercially available nasal prong and the antibacterial effect was evaluated both in vitro and in vivo in a first-in-human phase 1 trial. The coated nasal prongs had strong antibacterial activity against both Gram-negative and Gram-positive bacteria in vitro. In a randomized pre-clinical trial study of 24 + 24 healthy adult volunteers who carried coated or non-coated nasal prongs for 18 h, a 10log difference in mean bacterial colonization of 5.82 (p < 0.0001) was observed. These results show that this coating technique can prevent colonization by the normal skin and mucosal flora, and thus represent a promising novel technology for reduction of medical device-associated hospital acquired infections. PMID- 30274113 TI - VEGF delivery by smart polymeric PNIPAM nanoparticles affects both osteogenic and angiogenic capacities of human bone marrow stem cells. AB - OBJECTIVE: Bone tissue engineering (BTE) faces a major challenge with cell viability after implantation of a construct due to lack of functional vasculature within the implant. Human bone marrow derived mesenchymal stem cells (hBMSCs) have the potential to undergo transdifferentiation towards an endothelial cell phenotype, which may be appropriate for BTE in conjunction with the appropriate scaffolds and microenvironment. HYPOTHESIS AND METHODS: We hypothesized that slow delivery of vascular endothelial growth factor (VEGF) by using nanoparticles in combination with osteogenic stimuli might enhance both osteogenic and angiogenic differentiation of angiogenic primed hBMSCs cultured in an osteogenic microenvironment. Therefore, we developed a new strategy to enhance vascularization in BTE in vitro by synthesis of smart temperature sensitive poly(N-isopropylacrylamide) (PNIPAM) nanoparticles. We used PNIPAM nanoparticles loaded with collagen to investigate their ability to deliver VEGF for both angiogenic and osteogenic differentiation. RESULTS: We used the free radical polymerization technique to synthesize PNIPAM nanoparticles, which had particle sizes of approximately 100 nm at 37 degrees C and LCST of 30-32 degrees C. The cumulative VEGF release after 72 h for VEGF loaded PNIPAM (VEGF-PNIPAM) nanoparticles was 70%; for VEGF-PNIPAM loaded collagen hydrogels, it was 23%, which indicated slower release of VEGF in the VEGF-PNIPAM loaded collagen system. Immunocytochemistry (ICC) and inverted microscope visualization confirmed endothelial differentiation and capillary-like tube formation in the osteogenic culture medium after 14 days. Quantitative real-time polymerase chain reaction (QRT-PCR) also confirmed expressions of collagen type I (Col I), runt-related transcription factor 2 (RUNX2), and osteocalcin (OCN) osteogenic markers along with expressions of platelet-endothelial cell adhesion molecule-1 (CD31), von Willebrand factor (vWF), and kinase insert domain receptor (KDR) angiogenic markers. Our data clearly showed that VEGF released from PNIPAM nanoparticles and VEGF-PNIPAM loaded collagen hydrogel could significantly contribute to the quality of engineered bone tissue. PMID- 30274114 TI - Evaluation of biocompatible monomers as substitutes for TEGDMA in resin-based dental composites. AB - This works reports the synthesis and characterization of diallyl(5 (hydroxymethyl)-1,3-phenylene) dicarbonate (HMFBA) and 5-(hydroxymethyl)-1,3 phenylene bis(2-methylacrylate) (HMFBM) monomers and its evaluation as Bis-GMA eluents in the formulation of composite resins for dental use. The experimental materials formulated with HMFBA and HMFBM monomers presented flexural strength values similar to those of the control group formulated with Bis-GMA/TEGDMA. Regarding volumetric contraction percentage, the values obtained of experimental materials with HMFBA was 1.88% and for HMFBM was 4.15%, both lower than control resin (4.68%). In the case of double bond conversion, the resin formulated with HMFBA monomer exhibited a greater degree of conversion (87%). Besides, the DMA analyses proved that the values for Tg guarantee a good mechanical performance at body temperature. The new resins formulated with HMFBA and HMFBM monomers exhibit a cellular viability close to 100%, which indicates the absence of cytotoxicity towards fibroblastic cells. PMID- 30274115 TI - Anti-bacterial materials based on hyaluronic acid: Selection of research methodology and analysis of their anti-bacterial properties. AB - In the frame of the presented research, highly-porous structures made of hyaluronic acid modified with bioactive compounds were prepared. The method of microbiological testing of hygroscopic materials has been elaborated by verification of the JIS L 1902:2002 and ASTM E2149-13a test methods. The research has shown that the method developed in accordance with ASTM E2149-13a is suitable for testing the activity of hyaluronic acid samples against bacteria. E. coli and S. aureus. In the case of E. coli it is preferred to use as a medium the phosphoric buffer and for S. aureus NaCl solution from NB. By analysing the results of the antibacterial properties, it is important to note that the introduction of a small amount of zinc and zinc oxide in the matrix from the hyaluronic acid (in the amount of 3% by weight of the polymer) makes it possible to obtain a material with a strong activity against the bacterial strains. It enables to use this type of material as a treatment for hard-to-treat, infected wounds. On the other hand, using a relatively small dose of the cephalosporin antibiotic did not result in high levels of activity against the bacteria Gram "+" and Gram "-".

AB - Cerium selenium nanobiocomposites are novel lung cancer drug as they possess combined anti-cancer property of nanocomposite with l-asparaginase working in synergetic manner. Cerium selenium nanobiocomposites were synthesized using simple co-precipitation method. The size of the nanocomposite was found to be in the range 60-90 nm. Maximum absorption was observed using UV spectrum in the range of 350-490 nm. The nanobiocomposites was characterized using H-NMR and FTIR analysis it was found that secondary alkyl, allylic carbon, monosubstituted alkenes and sp2 hybridized CH bonds of alkenes were involved in binding of cerium and selenium nanoparticles with l-asparaginase for the formation of cerium selenium nanobiocomposite. The spherical shape of the cerium selenium nanobiocomposites were confirmed using SEM. Anticancer activity was checked by performing MTT assay resulting in 70.84% and 48.78% toxicity for maximum concentration of 1000 (MUg/ml) and IC50 concentration of 125 (MUg/ml) respectively on A549 lung cancer cell line using fluorescent microscopic analysis.

PMID- 30274118 TI - Surgical repair of abdominal wall defect with biomimetic nano/microfibrous hybrid scaffold. AB - It is universal to repair abdominal wall defects with prosthetic materials in abdominal surgery worldwide, which are associated with high complications and organ damage. At present, the composite nanofibers composed of natural and synthetic polymers as the new type of nano structure scaffold have attracted considerable attention in the field of tissue engineering. In this study we examined the feasibility of using electrospun silk fibroin (SF)/poly (3 hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) hybrid scaffolds for repairing of abdominal wall defects. Both in vivo and in vitro characterization were evaluated to access efficacy of the nanofiber for tissue regeneration. Our results showed that the electrospun SF/PHBV nanofiber scaffolds could stimulate the expression of TGF-beta1 and Collagen I in fibroblasts in vitro and then promote granulation and connective tissue depositions, but not result in a strong foreign body reaction in vivo. Moreover, we conjectured the potential molecular biological mechanism of SF/PHBV hybrid scaffolds in the process of tissue regeneration. Thus, the SF/PHBV hybrid nanofiber scaffolds have high efficiency and biocompatibility to repair abdominal wall defects. PMID- 30274119 TI - One-step fabrication and characterization of Fe3O4/HBPE-DDSA/INH nanoparticles with controlled drug release for treatment of tuberculosis. AB - In this study, Fe3O4/hyperbranched polyester-(2-dodecen-1-yl)succinic anhydride2 Dodecen-1-/isoniazid magnetic nanoparticles (Fe3O4/HBPE-DDSA/INH MNPs) with controlled drug release characteristics were synthesized successfully by a simple one-step method. Orthogonal experiments were performed to optimize the loading capacity and encapsulation efficiency of the MNPs. The structure of the Fe3O4/HBPE-DDSA/INH MNPs was characterized by 1H nuclear magnetic resonance spectroscopy, matrix-assisted laser desorption/ionization mass spectrometry, Fourier transform infrared spectroscopy, X-ray diffraction analysis, transmission electron microscopy, and superconducting quantum interference device measurements, while their properties were characterized based on swelling behavior observations, in-vitro release experiments, and cytotoxicity analysis. The results indicated that the fabricated Fe3O4/HBPE-DDSA/INH MNPs had a high drug-loading capacity and encapsulation efficiency. Further, the drug-release rate of the MNPs was higher in an acidic buffer, indicating that the MNPs were pH responsive. Swelling studies revealed that the MNPs exhibited diffusion controlled drug release, while in-vitro release studies revealed that the drug release properties could be controlled readily, owing to the high encapsulation efficiency of the MNPs and the uniform dispersion of the drug in them. These results collectively suggest that this multifunctional nontoxic drug delivery system, which exhibits good magnetic properties and pH-triggered drug-release characteristics, should be suitable for the treatment of tuberculosis. PMID- 30274120 TI - Effects of gallic acid biofabricated rGO nanosheets combined with radiofrequency radiation for the treatment of renal cell carcinoma. AB - The combination of biologically active compounds and nanomaterials in biomedicine field is growing rapidly and provided excellent forecasts for the progress of facile non-invasive approaches for the diagnosis of cancer therapy. In this present study, we demonstrated that as-prepared gallic acid (GA) coated reduced graphene oxide (rGO) combined with radiofrequency (RF) ablation has facilitated for the treatment of human renal epithelial cancer (A-489) cells without disturbing the renal proximal epithelial (HK-2) cells. The successful biofabrication of GA onto the rGO nanostructure has been elaborated with the support of peak intensities of diffracted X-ray patterns and Raman spectral visualizations. The micrograph imageries are displayed that the warped and ribbed structure containing wrinkled paper-like arrangement with multilayer structure of rGO with assistance of GA molecules. The synthesized GA-rGO nanomaterials exhibited a very good apoptosis and toxic effect on A-489 renal cancer cells, which was found to exhibit enhanced tumor cytotoxicity in RF combination treatment compared to RF treated alone. Moreover, the results are highly cheering to go for functionalized nanomaterial and RF radiation, combined drug delivery system to overcome the limitation to treat kidney cancers. PMID- 30274121 TI - Effects of graphene on the structure, properties, electro-response behaviors of GO/PAA composite hydrogels and influence of electro-mechanical coupling on BMSC differentiation. AB - Electro-responsive Graphene oxide-poly(acrylic acid) (GO-PAA) nanocomposite hydrogels with different concentrations of GO were successfully fabricated via in situ polymerization. The covalently crosslinked PAA network is intertwined with GO sheets by the bridging of hydrogen-bond interactions thus resulting in an integrated and stable hydrogel network. The swelling, mechanical and conductivity properties of the hydrogel are impacted as a result. The influences of different factors on the electro-response behavior of the hydrogels were deeply explored. Because of electrostatic double layer of the GO, the response properties of hydrogels in different voltage, pH, and ionic strength improved significantly. Meanwhile, with the addition of GO, the response performance of hydrogel in biological applications was greatly expanded. Furthermore, GO-PAA hydrogel shows a good compatibility with bone marrow-derived mesenchymal stem cells (BMSCs). The electro-mechanical coupling of the hydrogel can change the morphology of the adhesive cells, and regulate the cytoskeleton of the cell under the condition of electrical stimulation, which can further promote the differentiation of neural stem cells. This electro-responsive hydrogel could be widely used in many fields of biomedical application such as artificial muscle and tissue engineering scaffold. PMID- 30274122 TI - Novel core-shell dextran hybrid nanosystem for anti-viral drug delivery. AB - Zidovudine (AZT) is an antiviral drug extensively used for combating the global pandemic- HIV/AIDS. However, its uses are overshadowed by its short half -life, poor aqueous solubility and inability to cross physiological barriers. This study highlights a nanosystem consisting of dextran and stearic acid for AZT delivery. This hybrid nanoparticle was prepared by double emulsion solvent evaporation method. The morphological analysis of the prepared nanoparticles was carried out by transmission electron microscopy (TEM) and structural analysis through FTIR spectroscopy. Haemolysis, blood cell aggregation and cytotoxicity evaluations were also performed. These biological evaluations indicated that the nanoparticles were compatible and fluorescence microscopy studies demonstrated increased cellular internalization of drug loaded hybrid nanoparticles when compared with free drug molecules. The experimental outcomes indicate that the prepared nanoparticles are highly biocompatible haemocompatible and effective in getting internalized into cells of neural origin. These results highlight the feasibility and efficacy of the hybrid nanoparticles for effective delivery of zidovudine. PMID- 30274123 TI - "The return of ceramic implants": Rose stem inspired dual layered modification of ceramic scaffolds with improved mechanical and anti-infective properties. AB - Nowadays, traditional ceramics for bone implants have considerably replaced by metal based biomedical materials, attributing to the friability of ceramics. However, ceramic implants possess excellent biocompatibility and longtime abrasion resistance. They should be more desirable for long-term uses of implants in case their fragility had been overcome. In the present work, inspired from natural rose, a dual-layer-modified ceramic scaffold was constructed by coating a superplastic layer of isocyanate (ISO) resin and a nano Zinc Oxide (nano-ZnO) layer on the ceramic scaffold. The ISO resin modification layer with 1 mm thickness, improved the mechanical properties of ceramic implants 2-3 times, and protect the ceramic implants from broken even drop from 1 m high. Moreover, such dual layered modification exhibited broad spectrum antibacterial behavior. In vivo biocompatible studies demonstrated that there was no obvious noticeable tissue damage in all major organs of mice after the implant surgeries. PMID- 30274124 TI - Tuneable hydrogels of Caf1 protein fibers. AB - Capsular antigen fraction 1 (Caf1) is a robust polymeric protein forming a protective layer around the bacterium Yersinia pestis. Occurring as ~1 MUm polymeric fibers, it shares its immunoglobulin-like fold with the majority of mammalian extracellular proteins such as fibronectin and this structural similarity suggests that this unusual polymer could form useful mimics of the extracellular matrix. Driven by the pressing need for reliable animal-free 3D cell culture environments, we showed previously that recombinant Caf1 produced in Escherichia coli can be engineered to include bioactive peptides, which influence cell behavior. Here, we demonstrate that through chemical crosslinking with a small palette of PEG-based crosslinkers, Caf1-based hydrogels can be prepared displaying a wide range of mechanical and morphological properties that were studied by rheology, compressive testing, SDS-PAGE and scanning electron microscopy. By varying the Caf1 protein concentration, viscoelasticity and stiffness (~11-2300 Pa) are reproducibly tunable to match natural and commercial 3D gels. Hydrogel porosity and swelling ratios were found to be defined by crosslinker architecture and concentration. Finally the hydrogels, which are 95 99% water, were shown to retain the high stability of the native Caf1 protein in a range of aqueous conditions, including extended immersion in cell culture media. The unusual Caf1 polymer thus offers the possibility of presenting bioactive protein subunits in a precisely tuneable hydrogel for use in cell culture and drug delivery applications. PMID- 30274125 TI - A novel gold-based stimuli-responsive theranostic nanomedicine for chemo photothermal therapy of solid tumors. AB - The chemo-photothermal therapy performance of a novel theranostic nanoparticles that fabricated through the conjugation of HS-poly(epsilon-caprolactone)-block poly(N-isopropylacrylamide)-block-poly(acrylic acid) (HS-PCL-b-PNIPAAm-b-PAA) and gold nanoparticles (GNPs) was extensively investigated. The GNPs@polymer conjugate theranostic NPs was loaded with doxorubicin hydrochloride (DOX) as an anticancer drug through electrostatic interactions to afford GNPs@polymer-DOX theranostic nanomedicine. Temperature and pH-triggered in vitro drug release behavior of the developed theranostic nanomedicine were also examined. The biocompatibility of the synthesized GNPs@polymer theranostic NPs was confirmed through the assessing survival rate of breast cancer cell line (MCF7) using MTT assay. In vitro cytotoxic effects of the GNPs@polymer-DOX theranostic nanomedicine was also evaluated against MCF7 cells in both with or without laser irradiation (532 nm, 145 mJ per pulse, 5 min) conditions, and the results obtained were compared with free DOX as the reference. As the results, the developed GNPs@polymer-DOX can be considered as theranostic nanomedicine for chemo-photothermal therapy of solid tumors. PMID- 30274126 TI - 3D culture of neural stem cells within conductive PEDOT layer-assembled chitosan/gelatin scaffolds for neural tissue engineering. AB - Neural stem cells (NSCs), as a self-renewing and multipotent cell population, have been widely studied for never regeneration. Engineering scaffold is one of the important factors to regulate NSCs proliferation and differentiation towards the formation of the desired cells and tissues. Because neural cells are electro active ones, a conductive scaffold is required to provide three-dimensional cell growth microenvironments and appropriate synergistic cell guidance cues. In this study, a poly (3,4-ethylenedioxythiophene)/chitosan/gelatin (PEDOT/Cs/Gel) scaffold was prepared via in situ interfacial polymerization, with a nanostructured layer of PEDOT assembling on the channel surface of porous Cs/Gel scaffold. This electrically conductive, three-dimensional, porous and biodegradable PEDOT/Cs/Gel scaffold was used as a novel scaffold for NSCs three dimension (3D) culture in vitro. It was found that the layer of PEDOT on the channel surface of Cs/Gel scaffolds could greatly promote NSCs adhesion and proliferation. Additionally, under the differentiation condition, the protein and gene analysis suggested that PEDOT/Cs/Gel scaffolds could significantly enhance the NSCs differentiation towards neurons and astrocytes with the up-regulation of beta tubulin-III and GFAP expression. In conclusion, these results demonstrated that the PEDOT/Cs/Gel scaffolds as an electrically conductive scaffold could not only promote NSCs adhesion and proliferation but also enhance NSCs differentiation into neurons and astrocytes with higher protein and gene expression. PEDOT-assembled Cs/Gel scaffold will be a promising conductive substrate for NSCs research and neural tissue engineering. PMID- 30274127 TI - A water-soluble silver(I) formulation as an effective disinfectant of contact lenses cases. AB - The antibacterial effect of the already known water-soluble compound {[Ag6(MU3 Hmna)4(MU3-mna)2]2-.[(Et3NH)+]2.(DMSO)2.(H2O)} (AGMNA) (H2mna = 2-mercapto nicotinic acid) was evaluated by the mean of the Minimum Inhibitory Concentration (MIC), the Minimum Bactericidal Concentration (MBC) and the Inhibitory Zone (IZ), against the bacterial strains Pseudomonas aeruginosa (PAO1) and Staphylococcus aureus (St. aureus) which settle in the cornea, in bacterial keratitis. The MICs' of AGMNA against PAO1 and St. aureus were 25.7 +/- 2.4 MUM and 42.0 +/- 0.3 MUM respectively. Tauhe Biofilm Elimination Concentration (BetaEpsilonC) was used to evaluate the influence of AGMNA on the formation of biofilm of PAO1. AGMNA exhibits stronger antimicrobial activity than that of H2mna or AgNO3. The toxicity of AGMNA was examined against normal human corneal epithelial cells (HCET cells) and by micronucleus (MN) assay in HCET cells. Thus, the IC50 value of AGMNA, towards HCET cells is higher than 120 MUMU, while its effect on MN frequency, of HCET cells, is meaningless, when they are treated with it at 120 MUMU, suggesting no in vitro genotoxicity. The Mitotic Index (MI), Chromosomal Aberrations (CA) and Nuclear Abnormalities (NA) analyses of Allium cepa reveal insignificant variations between treated and untreated ones indicating no in vivo genotoxicity. PMID- 30274128 TI - Corrosion behaviour and cell interaction of Ti-6Al-4V alloy prepared by two techniques of 3D printing. AB - 3D printing seems to be the technology of the future for the preparation of metallic implants. For such applications, corrosion behaviour is pivotal. However, little is published on this topic and with inconsistent results. Therefore, we carried out a complex study in which we compared two techniques of the 3D printing technology - selective laser melting and electron beam melting. The corrosion behaviour was studied in physiological solution by standard electrochemical techniques and susceptibility to localised corrosion was estimated too. All samples showed typical passive behaviour. Localised corrosion was shown to be possible on the original as-printed surfaces. Corrosion experiments were repeated tree times. To reveal possible negative effects of 3D printing on cytocompatibility, direct in vitro tests were performed with U-2 OS cells. The cells showed good viability and proliferation, but their growth was impeded by surface unevenness. Our results suggest that both techniques are suitable for implants production. Statistical evaluation was performed by ANOVA followed by Tukey's test.

AB - Three different kinds of polyurethane (PU) micelles, i.e. PEG-c-PU, PEG-g-PU and PEG-b-PU, with hydrophobic PCL core and hydrophilic PEG corona were prepared by self-assembly method. DLS studies illustrated that PEG-g-PU micelles showed pH dependent surface charge switching properties while no obvious surface charge switching activities were found for PEG-b-PU and PEG-c-PU micelles. Triclosan was loaded into PCL core by dialysis method with pretty high encapsulate content and efficiency and the payloads were released at an accelerate rate in the presence of lipase. MIC and MBC studies demonstrated an enhanced antibacterial activity of encapsulated Triclosan against planktonic bacteria than free Triclosan. CLSM images of S. aureus biofilms treated with Nile red loaded PU micelles illustrated the penetration and accumulation of PEG-g-PU micelles inside the bacterial biofilms at an acidic environment. In addition, Triclosan loaded into PEG-g-PU micelles showed more potent antibiofilm activities than that loaded into PEG-c PEG and PEG-b-PU micelles. Therefore, the PEG-g-PU micelles can be potentially used as hydrophobic antibiotic carriers to treat bacterial infections and biofilms.

AB - : The development of dental adhesive resins with long-lasting antibacterial properties is a possible solution to overcome the problem of secondary caries in modern adhesive dentistry. OBJECTIVES: (i) Synthesis and characterization of nitrogen-doped titanium dioxide nanoparticles (N_TiO2), (ii) topographical, compositional and wettability characterization of thin-films (unaltered and experimental) and, (iii) antibacterial efficacy of N_TiO2-containing dental adhesives against Streptococcus mutans biofilms. MATERIALS AND METHODS: Nanoparticles were synthesized and characterized using different techniques. Specimens (diameter = 12 mm, thickness ? 15 MUm) of OptiBond Solo Plus (Kerr Corp., USA) and experimental adhesives [50, 67 and 80% (v/v)] were fabricated, photopolymerized (1000 mW/cm2, 1 min) and UV-sterilized (254 nm, 800,000 MUJ/cm2) for microscopy, spectroscopy, wettability and antibacterial testing. Wettability was assessed with a contact angle goniometer by dispensing water droplets (2 MUL) onto four random locations of each specimen (16 drops/group). Drop profiles were recorded (1 min, 25 frames/s, 37 degrees C) and contact angles were calculated at time = 0 s (thetaINITIAL) and time = 59 s (thetaFINAL). Antibacterial testing was performed by growing S. mutans (UA159-ldh, JM10) biofilms for either 3 or 24 h (anaerobic conditions, 37 degrees C) with or without continuous light irradiation (410 +/- 10 nm, 3 h = 38.75 J/cm2, 24 h = 310.07 J/cm2) against the surfaces of sterile specimens. RESULTS: N_TiO2 was successfully prepared using solvothermal methods. Doped-nanoparticles displayed higher light absorption levels when compared to undoped titania. Experimental adhesives demonstrated superior antibacterial efficacy in dark conditions. CONCLUSIONS: The findings presented herein suggest that N_TiO2 is a feasible antibacterial agent against cariogenic biofilms.

Scaffolds were required to have proper microstructure with suitable size, gradient, shape and porosity to mimic the specific three-dimensional structure of extracellular matrix. Taken the simple technique of freeze-drying, the nucleation and growth of ice crystals were affected by thermal behavior of solution during freezing process, which could be controlled to tailor and predict the pore structure in scaffold. This paper aimed to reveal the effect of containers' heat transfer capability on the thermal behaviors of solution, and then its influence to pore structure in scaffold. Four containers with different heat transfer capacity were adopted for cooling model to achieve different thermal characterizations within solution during cooling process. The vertical cross section of scaffold was observed by scanning electron microscopy. The porosity and tensile properties of scaffold were measured to depict scaffold characteristics. Scaffolds fabricated by containers with lambda/d = 20,000, 3000 and 450 W/m2. degrees C showed cellular pores with gradient. With the decrease of lambda/d, pores in scaffold were enlarged, and the wall between neighboring pores also became thicker. Pillared pores were produced only in container with lambda/d = 50 W/m2. degrees C, oriented along the vertical direction without gradient. This process demonstrated that by altering the container of cooling model, scaffold microstructure could be tailored. PMID- 30274132 TI - Multifunctional polymer coatings for titanium implants. AB - The aim of this work was to modify the surface of the titanium implants by application of multifunctional polymer coatings based on polyurethane and its composites with graphene and beta-TCP. Graphene was used as an antibacterial agent, TCP as a bioactive component, and polymer coating as a corrosion protection of metal. As a result, materials with different surface characteristic, from hydrophilic to hydrophobic, varying in bioactivity and biocompatibility, were obtained. Wettability of the materials was tested by the sessile drop method; surface roughness was assessed on the basis of Ra parameter, measured by contact profilometry. The surface characteristic was complemented by microhardness testing. Also, in vitro immersion tests in fluids and cell tests were performed. Obtained results suggest that it is possible to fabricate, on the surface of titanium implants, multifunctional composite coatings based on polyurethane, with optimal composition for bone surgery and dentistry applications. The study further showed that the chemical structure (composition) of the polymer and the graphene content are crucial in terms of biocompatibility of the final material, while addition of tricalcium phosphate affects its bioactivity. PMID- 30274133 TI - High toxicity of Bi(OH)3 and alpha-Bi2O3 nanoparticles towards malignant 9L and MCF-7 cells. AB - Here we report the extreme toxicity in vitro of Bi(OH)3 and alpha-Bi2O3 nanoparticles (NPs), obtained through a facile synthesis with an average single particle size of 6-10 nm, tested on malignant gliosarcoma 9L and MCF-7 human breast cancer cells. For both nanomaterials, clonogenic assays reveal a mortality of over 90% in 9L and MCF-7 cells for a concentration of 50 MUg/mL after incubation for 24 h. Moreover, the NPs show a significant mortality of up to 60% in the malignant cells at the very low concentration of 6.25 MUg/mL. In contrast, at the same concentration, the nanomaterials exhibit no noticeable mortality towards normal Madin-Darby canine kidney cells. The internalisation of the NPs was demonstrated using flow cytometry and confocal microscopy was used to investigate when the loss of cell viability starts. The NPs show a faster cell death in 9L cells compared with MCF-7 cells, demonstrated via the identification of apoptosis through increased sub G1 levels after 24 h of NP incubation. Cleavage is identified as the main apoptotic nuclear morphology in 9L, which suggests the presence of reactive oxygen species. PMID- 30274134 TI - Facile incorporation of REDV into porous silk fibroin scaffolds for enhancing vascularization of thick tissues. AB - Rapid neovascularization within scaffolds is critical for the regeneration of thick complex tissues. The surface immobilization of peptides and other active molecules have been explored to improve the vascularization capacity of implants. However, the rapid degradation of these molecules, the reaction conditions and cross-linking usually result in decreased vascularization capability. Here, we introduced a temperate, all-aqueous process to achieve bulk porous silk fibroin (SF) scaffolds. A temperature controlled process was used to induce the water stable structure by SF self-assembly. Arg-Glu-Asp-Val (REDV) peptides were added into SF solution and fixed within SF scaffolds during the self-assembly process. The results showed that the functionalized scaffolds markedly promoted the adhesion of endothelial cells in vitro. Moreover, the in vivo studies indicated enhanced cell infiltration in the bulk functionalized SF scaffolds and impressive vascularization at 4 weeks post-implantation. The functionalized scaffolds demonstrated excellent vascularization capability, providing an exciting biomaterial option for thick tissue regeneration. PMID- 30274135 TI - Aminopeptidase N (CD13) targeted MR and NIRF dual-modal imaging of ovarian tumor xenograft. AB - The development of tumor-specific imaging nanoprobes with the potential to improve the accuracy of cancer diagnosis has become an area of intense research. Aminopeptidase N (CD13) predominantly expresses on the surface of ovarian tumor cells and can be specifically recognized by Asn-Gly-Arg (NGR) peptide. The applicability of CD13 as a target for specific ovarian tumor imaging, however, remains unexploited so far. In this study, Cy5.5-labeled, NGR-conjugated iron oxide nanoparticles (Cy5.5-NGR-Fe3O4 NPs) were prepared as an ovarian tumor specific bimodal imaging nanoprobe. It is demonstrated that the conjugation of NGR targeting moiety leads to a higher cellular uptake toward ES-2 cells, the human ovarian carcinoma cells that highly express CD13. Moreover, magnetic resonance imaging of ovarian tumor xenograft reveals that the Fe3O4-Cy5.5-NGR NPs results in a significant T2* signal reduction in the tumor. Meanwhile, near infrared fluorescence imaging indicates a higher accumulation of Fe3O4-Cy5.5-NGR NPs in the tumor xenograft. Therefore, CD13 could be applied as a novel and efficient target for constructing ovarian tumor specific nanoprobes with improved accuracy for ovarian tumor diagnosis. PMID- 30274137 TI - In-vitro and in-vivo, cytotoxicity evaluation of cast functionally graded biomaterials for dental implantology. AB - An innovative technique of casting the titanium implant alloys and its calcium phosphate coating using centrifugal casting method was proposed in the current study. This one-step, self-coating technique results in formation of functionally graded biomaterials (FGBMs) of calcium phosphate/Titanium alloys. Two groups of samples (Group 1 and Group 2) were prepared utilizing self-coated titanium niobium (Ti-6Al-7Nb) and titanium- vanadium (Ti-6Al-4V) alloys respectively. The cast samples were then prepared for in-vitro cytocompatibility evaluation, in vivo systemic toxicity and osseointegration evaluation. Cytocompatibility was examined in-vitro on human bone osteosarcoma cells (Saos-2). In-vivo surgical implantation of the samples in the mandible of the experimental dogs was correspondingly implemented. Tests for systemic toxicity, X-ray images, Dual Energy X-ray Absorptiometry (DEXA) and histopathological analysis were obtained for each dog's mandible sample. In-vitro cytocompatibility studies revealed high cytocompatibility of Group 2 in comparison to Group 1. In-vivo results proved safety of Group 2 as regards to systemic toxicity. On the other hand, results of the X-ray images, DEXA and histopathological analysis revealed comparable osseointegration potential of both groups. These results suggest the use of Group2-FGBMs in dental implant manufacturing and prove that FGBMs prepared by centrifugal casting as self-coated implants have good biocompatibility and osseointegration capability. PMID- 30274136 TI - Development of three-dimensional printing polymer-ceramic scaffolds with enhanced compressive properties and tuneable resorption. AB - In this study, bone tissue engineered scaffolds fabricated via powder-based 3D printing from hydroxyapatite (HA) and calcium sulphate (CaSO4) powders were investigated. The combination of using a fast resorbing CaSO4 based powder and the relatively slower HA powder represents a promising prospect for tuning the bioresorption of 3D printed (3DP) scaffolds. These properties could then be tailored to coincide with tissue growth rate for different surgical procedures. The manufactured scaffolds were infiltrated with poly(epsilon-caprolactone) (PCL). The PCL infiltrated the inter-particle spacing within the 3DP structures due to the nature of a loosely-packed powder bed and also covered the surface of ceramic-based scaffolds. Consequently, the average compressive strength, compressive modulus and toughness increased by 314%, 465% and 867%, respectively. The resorption behaviour of the 3DP scaffolds was characterised in vitro using a high-throughput system that mimicked the physiological environment and dynamic flow conditions relevant to the human body. A rapid release of CaSO4 between Day 0 and 28 was commensurate with a reduction in scaffold mass and compressive properties, as well as an increase in medium absorption. In spite of this, HA particles, connected by PCL fibrils, remained within the microstructure after 56 days resorption under dynamic conditions. Consequently, a high level of structural integrity was maintained within the 3DP scaffold. This study presented a porous PCL-HA-CaSO4 3DP structure with the potential to encourage new tissue growth during the initial stages of implantation and also offering sufficient structural and mechanical support during the bone healing phase. PMID- 30274138 TI - Photoactivated water-disinfecting, and biological properties of Ag NPs@Sm-doped ZnO nanorods/cuttlefish bone composite: In-vitro bactericidal, cercaricidal and schistosomicidal studies. AB - Herein, eco-friendly composite was synthesized by embedding silver (Ag) nanospheres onto aragonitic cuttlefish bone (CB)-stabilized samarium doped zinc oxide (Sm-doped ZnO) nanorods. The operating interaction profile and the photoactive behavior of this nanocomposite were assessed via XRD, FTIR, Raman, TEM, FE-SEM, DLS, DRS and PL techniques. Locality of Sm-doped ZnO and its attaching modes to the cuttlefish bone lamella were highly dominated by embedding Ag NPs that encouraged Zn2+ Lewis acid sites to electrostatically interact with aragonite carbonates in the channeled porous CB system. Such interacting approach enhanced photoactivity of Sm-doped ZnO by lowering its energy band gap (from 3.26 eV for Sm-doped ZnO/CB to 2.12 eV for Ag@Sm-doped ZnO/CB). Besides, plasmon induced silver electrons provided Sm-doped ZnO by extra photosensitivity. Ag@Sm doped ZnO/CB nanocomposite exhibited pronounced photo-activated disinfection efficiencies for Staphylococcus aureus (80%), Pseudomonas aeruginosa (60%), and Schistosoma mansoni cercariae (100%) linked with progressive demolition in cercarial body. Such nanocomposite also possessed exterminating action against Schistosoma mansoni adult worms serving near 100% worm-mortality accompanied by significant disintegration of worm body. These findings were successfully drawn Ag@Sm-doped ZnO/CB as an efficient weapon in the biocides arsenal being even capable of destructing pathogenic bacteria and parasites in dark- and photo- conditions.

AB - Background: This study aimed to understand attitudes of HIV/AIDS follow-up workers regarding task shifting, reveal the current conditions of this implementation, as well as to find out any challenges of early-stage implementation. Methods: Taking Jiangxi Province as an example, a cross-sectional survey with 102 health professionals in CDCs (Centers for Disease Control and Prevention) and 92 health care providers in primary health institutions was conducted from November 2016 to January 2017. This survey includes the demographic backgrounds of participants, their attitudes towards task shifting, and the main difficulties faced in their work, etc. Results: 60.8% of professionals and 77.2% of providers hold positive attitudes towards task shifting. Both health professionals and providers express their concerns about unclear and undefined funds distribution and lack of confidentiality of PLWHA (people living with HIV) in local primary health institutions. Conclusions: The majority of health workers hold positive attitudes towards task shifting. It also highlights some negative reactions in implementation, and reveals the main difficulties that constitute barriers to follow-up. Findings from this study may provide evidence for enhancing future implementation of task shifting. PMID- 30274140 TI - Subchronic Toxicity Studies of Cortex Dictamni Extracts in Mice and Its Potential Hepatotoxicity Mechanisms in Vitro. AB - Cortex Dictamni is a commonly-used traditional Chinese herbal medicine for the treatment of skin inflammation, tinea, and eczema. Recently, some studies reported that Cortex Dictamni might induce liver injury, suggesting more attention to its safety. The current study was designed to investigate subchronic toxicity of Cortex Dictamni aqueous extract (CDAE) and ethanol extract (CDEE) in mice and the potential hepatotoxicity mechanisms in vitro. Firstly, CDAE or CDEE groups were administrated with varying dosages (2.3, 4.6, or 9.2 g/kg/day, p.o.) in mice for 28 days in subchronic toxicity studies. General clinical signs and biochemical parameters were examined, and morphological analyses were conducted. Secondly, we identified the different constituents of CDAE and CDEE using HPLC MS/MS and chose major components for further study. In order to determine the toxic components, we investigated the cytotoxicity of extracts and chosen components using CCK-8 assay in HepG2 cells. Furthermore, we explored the possible hepatotoxicity mechanisms of Cortex Dictamni using a high content analysis (HCA). The results showed that no significant differences of general clinical signs were observed in mice. Aspartate alanine aminotransferase (ALT) and aminotransferase (AST) were significantly increased in the high-dose CDAE and CDEE groups compared to the control group. Meanwhile, the absolute and relative liver weights and liver/brain ratio were significantly elevated, and histological examination of liver demonstrated cellular enlargement or nuclear shrinkage. In UPLC analysis, we compared the chemical constituents between CDAE and CDEE, and chose dictamnine, obakunone, and fraxinellone for hepatotoxicity evaluation in the in vitro studies. In the CCK-8 assay, CDAE, CDEE, dictamnine, obakunone, and fraxinellone decreased the cell viability in a dose-dependent manner after treatment for 48 h. Furthermore, the cell number decreased, while the nuclear intensity, cell membrane permeability, and concentration of reactive oxygen species were shown to increase, meanwhile, mitochondrial membrane potential was also changed in HepG2 cells following 48 h of compounds treatment using HCA. Our studies suggested that CDAE and CDEE have potential hepatotoxicity, and that the alcohol extraction process could increase toxicity. Dictamnine, obakunone, and fraxinellone may be the possible toxic components in Cortex Dictamni with dictamnine as the most potentially hepatotoxic component, whose potential hepatotoxicity mechanism may be associated with cell apoptosis. Moreover, this study could provide valuable data for clinical drug safety research of Cortex Dictamni and a good example for safety study of other Chinese herbal medicines. PMID- 30274141 TI - Health and Well-Being of Cisgender, Transgender and Non-Binary Young People. AB - Young transgender and non-binary individuals (TNBI) are exposed to situations of discrimination and have a greater risk of violence. The purpose of this study is to analyze which protective, violence and health and well-being factors have more influence on TNBI compared to cisgender people. The sample comprised 856 youth between 14 and 25 years old. A survey including questions about sociodemographic information and protective, violence and health and well-being factors was designed ad hoc for this study. The results show the non-binary group received the least support from family and friends, higher risk of suffering cyberbullying, and many feel isolated and unhappy. TNBI have suffered more verbal attacks both inside and outside their school and physical attacks at school than cisgender young. These results are important because they may contribute to the promotion of public policies and clinical interventions that favor the integration of TNBI in our society. PMID- 30274142 TI - Ostreid Herpesvirus-1 Infects Specific Hemocytes in Ark Clam, Scapharca broughtonii. AB - High levels of ostreid herpesvirus 1 (OsHV-1) were detected in hemocytes of OsHV 1 infected mollusks. Mollusk hemocytes are comprised of different cell types with morphological and functional heterogeneity. Granular cells are considered the main immunocompetent hemocytes. This study aimed to ascertain if OsHV-1 infects specific types of hemocytes in ark clams. Types of hemocytes were first characterized through microexamination and flow cytometry. In addition to a large group of red cells, there were three types of recognizable granular cells in ark clams. Type II granular cells were mostly found with OsHV-1 infection by transmission electron microscope (TEM) examination, and represented the hemocyte type that was susceptible to OsHV-1 infection. The subcellular location of OsHV-1 particles in apoptotic type II granular cells was further analyzed. Some OsHV-1 particles were free inside the apoptotic cells, which may contribute to OsHV-1 transmission among cells in the host, some particles were also found enclosed inside apoptotic bodies. Apoptosis is an important part of the host defense system, but might also be hijacked by OsHV-1 as a strategy to escape host immune attack. Following this investigation, a primary culture of type II granular cells with OsHV-1 infection would facilitate the research on the interaction between OsHV-1 and mollusk hosts. PMID- 30274143 TI - Physical Principles of a Piezo Accelerometer Sensitive to a Nearly Constant Signal. AB - The paper considers the construction of a piezoelectric accelerometer capable of measuring constant linear acceleration. A number of designs are proposed that make it possible to achieve high sensitivity with small dimensions and a wide frequency band (from 10-5 Hz). The finite element model of the proposed design was investigated, and its output characteristic and scale factor (36 mV/g) were obtained. PMID- 30274145 TI - Tungsten-Embedded Graphene: Theoretical Study on a Potential High-Activity Catalyst toward CO Oxidation. AB - The oxidation mechanism of CO on W-embedded graphene was investigated by M06-2X density functional theory. Two models of tungsten atom embedded in single and double vacancy (W-SV and W-DV) graphene sheets were considered. It was found that over W-SV-graphene and W-DV-graphene, the oxidation of CO prefers to Langmuir Hinshelwood (LH) and Eley-Rideal (ER) mechanism, respectively. The two surfaces exhibit different catalytic activity during different reaction stages. The present results imply that W-embedded graphene is a promising catalyst for CO oxidation, which provides a useful reference for the design of a high-efficiency catalyst in detecting and removing of toxic gases. PMID- 30274144 TI - The Development of a Database for Herbal and Dietary Supplement Induced Liver Toxicity. AB - The growing use of herbal dietary supplements (HDS) in the United States provides compelling evidence for risk of herbal-induced liver injury (HILI). Information on HDS products was retrieved from MedlinePlus of the U.S. National Library of Medicine and the herbal monograph of the European Medicines Agency. The hepatotoxic potential of HDS was ascertained by considering published case reports. Other relevant data were collected from governmental documents, public databases, web sources, and the literature. We collected information for 296 unique HDS products. Evidence of hepatotoxicity was reported for 67, that is 1 in 5, of these HDS products. The database revealed an apparent gender preponderance with women representing 61% of HILI cases. Culprit hepatotoxic HDS were mostly used for weight control, followed by pain and inflammation, mental stress, and mood disorders. Commonly discussed mechanistic events associated with HILI are reactive metabolites and oxidative stress, mitochondrial injury, as well as inhibition of transporters. HDS-drug interactions, causing both synergistic and antagonizing effects of drugs, were also reported for certain HDS. The database contains information for nearly 300 commonly used HDS products to provide a single-entry point for better comprehension of their impact on public health. PMID- 30274146 TI - Insights into the Structural Requirements of 2(S)-Amino-6-Boronohexanoic Acid Derivatives as Arginase I Inhibitors: 3D-QSAR, Docking, and Interaction Fingerprint Studies. AB - Human arginase I (hARGI) is an important enzyme involved in the urea cycle; its overexpression has been associated to cardiovascular and cerebrovascular diseases. In the last years, several congeneric sets of hARGI inhibitors have been reported with possible beneficial roles for the cardiovascular system. At the same time, crystallographic data have been reported including hARGI-inhibitor complexes, which can be considered for the design of novel inhibitors. In this work, the structure-activity relationship (SAR) of Calpha substituted 2(S)-amino 6-boronohexanoic acid (ABH) derivatives as hARGI inhibitors was studied by using a three-dimensional quantitative structure-activity relationships (3D-QSAR) method. The predictivity of the obtained 3D-QSAR model was demonstrated by using internal and external validation experiments. The best model revealed that the differential hARGI inhibitory activities of the ABH derivatives can be described by using steric and electrostatic fields; the local effects of these fields in the activity are presented. In addition, binding modes of the above-mentioned compounds inside the hARGI binding site were obtained by using molecular docking. It was found that ABH derivatives adopted the same orientation reported for ABH within the hARGI active site, with the substituents at Calpha exposed to the solvent with interactions with residues at the entrance of the binding site. The hARGI residues involved in chemical interactions with inhibitors were identified by using an interaction fingerprints (IFPs) analysis. PMID- 30274147 TI - Inhibitory Antibodies against Activin A and TGF-beta Reduce Self-Supported, but Not Soluble Factors-Induced Growth of Human Pulmonary Arterial Vascular Smooth Muscle Cells in Pulmonary Arterial Hypertension. AB - Increased growth and proliferation of distal pulmonary artery vascular smooth muscle cells (PAVSMC) is an important pathological component of pulmonary arterial hypertension (PAH). Transforming Growth Factor-beta (TGF-beta) superfamily plays a critical role in PAH, but relative impacts of self-secreted Activin A, Gremlin1, and TGF-beta on PAH PAVSMC growth and proliferation are not studied. Here we report that hyper-proliferative human PAH PAVSMC have elevated secretion of TGF-beta1 and, to a lesser extent, Activin A, but not Gremlin 1, and significantly reduced Ser465/467-Smad2 and Ser423/425-Smad3 phosphorylation compared to controls. Media, conditioned by PAH PAVSMC, markedly increased Ser465/467-Smad2, Ser423/425-Smad3, and Ser463/465-Smad1/5 phosphorylation, up regulated Akt, ERK1/2, and p38 MAPK, and induced significant proliferation of non diseased PAVSMC. Inhibitory anti-Activin A antibody reduced PAH PAVSMC growth without affecting canonical (Smads) or non-canonical (Akt, ERK1/2, p38 MAPK) effectors. Inhibitory anti-TGF-beta antibody significantly reduced P-Smad3, P ERK1/2 and proliferation of PAH PAVSMC, while anti-Gremlin 1 had no anti proliferative effect. PDGF-BB diminished inhibitory effects of anti-Activin A and anti-TGF-beta antibodies. None of the antibodies affected growth and proliferation of non-diseased PAVSMC induced by PAH PAVSMC-secreted factors. Together, these data demonstrate that human PAH PAVSMC have secretory, proliferative phenotype that could be targeted by anti-Activin A and anti-TGF beta antibodies; potential cross-talk with PDGF-BB should be considered while developing therapeutic interventions.

AB - Methionine sulfoxide reductases (MSRA1 and MSRB) are proteins overproduced in Staphylococcus aureus during exposure with cell wall-active antibiotics. Later studies identified the presence of two additional MSRA proteins (MSRA2 and MSRA3) in S. aureus. These MSR proteins have been characterized in many other bacteria as well. This review provides the current knowledge about the conditions and regulatory network that mimic the expression of these MSR encoding genes and their role in defense from oxidative stress and virulence. PMID- 30274149 TI - Role of Hydrogen Sulfide in NRF2- and Sirtuin-Dependent Maintenance of Cellular Redox Balance. AB - Hydrogen sulfide (H2S) has arisen as a critical gasotransmitter signaling molecule modulating cellular biological events related to health and diseases in heart, brain, liver, vascular systems and immune response. Three enzymes mediate the endogenous production of H2S: cystathione beta-synthase (CBS), cystathione gamma-lyase (CSE) and 3-mercaptopyruvate sulfurtransferase (3-MST). CBS and CSE localizations are organ-specific. 3-MST is a mitochondrial and cytosolic enzyme. The generation of H2S is firmly regulated by these enzymes under normal physiological conditions. Recent studies have highlighted the role of H2S in cellular redox homeostasis, as it displays significant antioxidant properties. H2S exerts antioxidant effects through several mechanisms, such as quenching reactive oxygen species (ROS) and reactive nitrogen species (RNS), by modulating cellular levels of glutathione (GSH) and thioredoxin (Trx-1) or increasing expression of antioxidant enzymes (AOE), by activating the transcription factor nuclear factor (erythroid-derived 2)-like 2 (NRF2). H2S also influences the activity of the histone deacetylase protein family of sirtuins, which plays an important role in inhibiting oxidative stress in cardiomyocytes and during the aging process by modulating AOE gene expression. This review focuses on the role of H2S in NRF2 and sirtuin signaling pathways as they are related to cellular redox homeostasis. PMID- 30274150 TI - The Effects of an Urban Forest Health Intervention Program on Physical Activity, Substance Abuse, Psychosomatic Symptoms, and Life Satisfaction among Adolescents. AB - Background: At-risk adolescents have been defined as youth who are or might be in physical, mental, or emotional danger. An Urban Forest Health Intervention Program (UFHIP) was formed at a center for at-risk adolescents in Israel, in order to promote physical activity and reduce risky behavior. Objective: To evaluate the intervention's effect on physical activity, smoking, alcohol consumption, psychosomatic symptoms, and life satisfaction. Methods: From 2015 to 2016, at-risk youth were nonrandomly selected to participate in the UFHIP. Questionnaires were administered to both intervention and control groups before and after the intervention. Univariate and multivariable analyses evaluated the intervention's effect. Results: The study participants (n = 53) showed 0.81 more sessions per week of 60 min of physical activity than did the control group (n = 23; p = 0.003). Among the intervention group, smoking frequency reduced from a mean of 2.60 (SD = 1.30) to 1.72 (SD = 1.08), whereas that in the control group increased from 3.17 (1.03) to 3.39 (1.03). In both groups, there was a reduction in alcohol consumption, with a greater change among intervention participants: 1.08 (SD = 1.30), compared with -0.09 (SD = 1.79) in the control group. Conclusions: Findings indicate that the environmental intervention was efficacious in increasing physical activity and reducing risky behaviors among youth. The effectiveness of this intervention among larger samples is warranted in future prospective studies. PMID- 30274151 TI - Effect of Colloidal Silica on the Hydration Behavior of Calcium Aluminate Cement. AB - The effect of colloidal silica (CS) on the hydrate phases and microstructure evolution of calcium aluminate cement (CAC) was investigated. Samples hydrated with CS were obtained and characterized by X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Fourier Transform Infrared spectroscopy (FT-IR), hydration heat measurement and Nuclear Magnetic Resonance (NMR). The results revealed that SiO2 nanoparticles may affect the hydrates crystallization process. There was a compact structure in the CAC paste with CS, while petal-shaped hydrates with a porous structure were formed in the pure CAC paste. The maximum value of electrical conductivity for CAC paste with CS suggested that the early stage of hydration for CAC was accelerated. However, the hydration heat curves revealed that the late stage of the CAC hydration process was inhibited, and the hydration degree was reduced, this result was in accordance with Thermogravimetry-Differential scanning calorimetry(TG-DSC) curves. The fitting results of hydration heat curves further showed that the hydration degree at NG (nucleation and crystal growth) process stage was promoted, while it was limited at the phase boundaries stage, and the diffusion stage in the hydration reaction was brought forward due to the addition of CS. According to these results and analyses, the differences in the hydration process for CAC with and without CS can be attributed to the distribution and nucleation effect of SiO2 nanoparticles.

AB - NiAl-based composites reinforced by CrMnFeCoNi high-entropy alloy (HEA) particles were fabricated by mechanical alloying (MA) and spark plasma sintering (SPS). The microstructure, mechanical, and tribological properties of the NiAl-HEA composites were investigated. Microstructural analyses show that after SPS, the HEA phase homogenously distributed in the NiAl matrix. Non-uniform diffusion of various elements occurred during the high temperature sintering process. Transmission electron microscope (TEM) observation of the composites revealed that many nano particle of Al2O3 generated at the grain boundary. The yield strength significantly increased after adding HEA particles. The compressive strength of the composites increased with the contents of HEA increasing, which should be attributed to the second phase hardening effect of HEA particles and fine grain strengthening effect. The composite of 10 wt.% HEA exhibited significant room temperature compressive properties, with the ultimate compressive strength of 2692 MPa and the compressive strain of 34.2%, respectively. The results of the wear tests show that the addition of HEA will reduce the wear resistance of composites to some extent and slightly increase the coefficients of friction (COFs) of the composites.

AB - The chemotherapeutic agent temozolomide (TMZ) kills tumor cells preferentially via alkylation of the O6-position of guanine. However, cells that express the DNA repair enzyme O6-methylguanine-DNA methyltransferase (MGMT), or harbor deficient DNA mismatch repair (MMR) function, are profoundly resistant to this drug. TMZ is in clinical use for melanoma, but objective response rates are low, even when TMZ is combined with O6-benzylguanine (O6BG), a potent MGMT inhibitor. We used in vitro and in vivo models of melanoma to characterize the early events leading to cellular TMZ resistance. Melanoma cell lines were exposed to a single treatment with TMZ, at physiologically relevant concentrations, in the absence or presence of O6BG. Surviving clones and mass cultures were analyzed by Western blot, colony formation assays, and DNA methylation studies. Mice with melanoma xenografts received TMZ treatment, and tumor tissue was analyzed by immunohistochemistry. We found that MGMT-negative melanoma cell cultures, before any drug treatment, already harbored a small fraction of MGMT-positive cells, which survived TMZ treatment and promptly became the dominant cell type within the surviving population. The MGMT-negative status in individual cells was not stable, as clonal selection of MGMT-negative cells again resulted in a mixed population harboring MGMT-positive, TMZ-resistant cells. Blocking the survival advantage of MGMT via the addition of O6BG still resulted in surviving clones, although at much lower frequency and independent of MGMT, and the resistance mechanism of these clones was based on a common lack of expression of MSH6, a key MMR enzyme. TMZ treatment of mice implanted with MGMT-negative melanoma cells resulted in effective tumor growth delay, but eventually tumor growth resumed, with tumor tissue having become MGMT positive. Altogether, these data reveal stochastic expression of MGMT as a pre-existing, key determinant of TMZ resistance in melanoma cell lines. Although MGMT activity can effectively be eliminated by pharmacologic intervention with O6BG, additional layers of TMZ resistance, although considerably rarer, are present as well and minimize the cytotoxic impact of TMZ/O6BG combination treatment. Our results provide rational explanations regarding clinical observations, where the TMZ/O6BG regimen has yielded mostly disappointing outcomes in melanoma patients.

Presl Bark Extracts, Improves Hyperuricemia through Inhibition of Xanthine Oxidase Activity and Increasing Urine Excretion. AB - Chrysanthemum indicum Linne flower (CF) and Cinnamomum cassia (L.) J. Presl bark (CB) extracts have been used as the main ingredients in several prescriptions to treat the hyperuricemia and gout in traditional medicine. In the present study, we investigated the antihyperuricemic effects of DKB114, a CF, and CB mixture, and the underlying mechanisms in vitro and in vivo. DKB114 markedly reduced serum uric acid levels in normal rats and rats with PO-induced hyperuricemia, while increasing renal uric acid excretion. Furthermore, it inhibited the activity of xanthine oxidase (XOD) in vitro and in the liver in addition to reducing hepatic uric acid production. DKB114 decreased cellular uric acid uptake in oocytes and HEK293 cells expressing human urate transporter (hURAT)1 and decreased the protein expression levels of urate transporters, URAT1, and glucose transporter, GLUT9, associated with the reabsorption of uric acid in the kidney. DKB114 exerts antihyperuricemic effects and uricosuric effects, which are accompanied, partially, by a reduction in the production of uric acid and promotion of uric acid excretion via the inhibition of XOD activity and reabsorption of uric acid. Therefore, it may have potential as a treatment for hyperuricemia and gout. PMID- 30274155 TI - Molecular Application of Aptamers in the Diagnosis and Treatment of Cancer and Communicable Diseases. AB - Cancer and infectious diseases such as Ebola, HIV, tuberculosis, Zika, hepatitis, measles and human schistosomiasis are serious global health hazards. The increasing annual morbidities and mortalities of these diseases have been blamed on drug resistance and the inefficacy of available diagnostic tools, particularly those which are immunologically-based. Antibody-based tools rely solely on antibody production for diagnosis and for this reason they are the major cause of diagnostic delays. Unfortunately, the control of these diseases depends on early detection and administration of effective treatment therefore any diagnostic delay is a huge challenge to curbing these diseases. Hence, there is a need for alternative diagnostic tools, discovery and development of novel therapeutic agents. Studies have demonstrated that aptamers could potentially offer one of the best solutions to these problems. Aptamers are short sequences of either DNA or RNA molecules, which are identified in vitro through a SELEX process. They are sensitive and bind specifically to target molecules. Their promising features suggest they may serve as better diagnostic agents and can be used as drug carriers for therapeutic purposes. In this article, we review the applications of aptamers in the theranostics of cancer and some infectious diseases. PMID- 30274156 TI - Novel Biocomposite Engineering and Bio-Applications. PMID- 30274157 TI - Implementing Morpholino-Based Nucleic Acid Sensing on a Portable Surface Plasmon Resonance Instrument for Future Application in Environmental Monitoring. AB - A portable surface plasmon resonance (SPR) instrument was tested for the first time for the detection of oligonucleotide sequences derived from the 16S rRNA gene of Oleispira antarctica RB-8, a bioindicator species of marine oil contamination, using morpholino-functionalized sensor surfaces. We evaluated the stability and specificity of morpholino coated sensor surfaces and tested two signal amplification regimes: (1) sequential injection of sample followed by magnetic bead amplifier and (2) a single injection of magnetic bead captured oligo. We found that the sensor surfaces could be regenerated for at least 85 consecutive sample injections without significant loss of signal intensity. Regarding specificity, the assay clearly differentiated analytes with only one or two mismatches. Signal intensities of mismatch oligos were lower than the exact match target at identical concentrations down to 200 nM, in standard phosphate buffered saline with 0.1 % Tween-20 added. Signal amplification was achieved with both strategies; however, significantly higher response was observed with the sequential approach (up to 16-fold), where first the binding of biotin-probe labeled target oligo took place on the sensor surface, followed by the binding of the streptavidin magnetic beads onto the immobilized targets. Our experiments so far indicate that a simple coating procedure in combination with a relatively cost-efficient magnetic-bead-based signal amplification will provide robust SPR based nucleic acid sensing down to 0.5 nM of a 45-nucleotide long oligo target (7.2 ng/mL). PMID- 30274158 TI - Characterization of Distributed Microfabricated Strain Gauges on Stretchable Sensor Networks for Structural Applications. AB - Smart structures mimic biological systems by using thousands of sensors serving as a nervous system analog. One approach to give structures this sensing ability is to develop a multifunctional sensor network. Previous work has demonstrated stretchable sensor networks consisting of temperature sensors and impact detectors for monitoring external environments and interacting with other objects. The objective of this work is to develop distributed, robust and reliable strain gauges for obtaining the strain distribution of a designated region on the target structure. Here, we report a stretchable network that has 27 rosette strain gauges, 6 resistive temperature devices and 8 piezoelectric transducers symmetrically distributed over an area of 150 * 150 mm to map and quantify multiple physical stimuli with a spatial resolution of 2.5 * 2.5 mm. We performed computational modeling of the network stretching process to improve measurement accuracy and conducted experimental characterizations of the microfabricated strain gauges to verify their gauge factor and temperature coefficient. Collectively, the results represent a robust and reliable sensing system that is able to generate a distributed strain profile of a common structure. The reported strain gauge network may find a wide range of applications in morphing wings, smart buildings, autonomous cars and intelligent robots. PMID- 30274159 TI - Antimicrobial Resistance in Class 1 Integron-Positive Shiga Toxin-Producing Escherichia coli Isolated from Cattle, Pigs, Food and Farm Environment. AB - The aim of this study was to investigate the presence of class 1 integrons in a collection of Shiga toxin-producing Escherichia coli (STEC) from different origins and to characterize pheno- and genotypically the antimicrobial resistance associated to them. A collection of 649 isolates were screened for the class 1 integrase gene (intI1) by Polymerase chain reaction The variable region of class 1 integrons was amplified and sequenced. Positive strains were evaluated for the presence of antimicrobial resistance genes with microarray and for antimicrobial susceptibility by the disk diffusion method. Seven out of 649 STEC strains some to serogroups, O26, O103 and O130 isolated from cattle, chicken burger, farm environment and pigs were identified as positive for intl1. Different arrangements of gene cassettes were detected in the variable region of class 1 integron: dfrA16, aadA23 and dfrA1-aadA1. In almost all strains, phenotypic resistance to streptomycin, tetracycline, trimethoprim/sulfamethoxazole, and sulfisoxazole was observed. Microarray analyses showed that most of the isolates carried four or more antimicrobial resistance markers and STEC strains were categorized as Multridrug-resistant. Although antimicrobials are not usually used in the treatment of STEC infections, the presence of Multridrug-resistant in isolates collected from farm and food represents a risk for animal and human health. PMID- 30274160 TI - Physiological Effects of Touching the Wood of Hinoki Cypress (Chamaecyparis obtusa) with the Soles of the Feet. AB - We clarified the physiological effects of tactile stimulation of the soles of the feet with the wood of the Hinoki cypress (Chamaecyparis obtusa) based on measurements of prefrontal cortex and autonomic nervous activities. Nineteen female university-attending students (age: 21.2 +/- 0.3 years) were included. Oxy hemoglobin (oxy-Hb) concentrations in the prefrontal cortex were determined by using near-infrared time-resolved spectroscopy. The high frequency (HF) indicating parasympathetic nervous activity and the ratio of low frequency (LF)/HF indicating sympathetic nervous activity were measured using heart rate variability. To evaluate the psychological effects caused by contact with the materials, the modified semantic differential method was used. The soles of the participants' feet were touched to a 600 * 600-mm plate made of Hinoki, which was finished in non-coating and brushing for 90 s. A marble plate served as the control. Next, subjective evaluation tests were administered to the participants. Compared with touching marble, touching Hinoki significantly (1) decreased the oxy-Hb concentrations in the left and right prefrontal cortices, which indicates decreased prefrontal cortex activity, (2) increased ln(HF), which indicates increased parasympathetic nervous activity, (3) decreased ln(LF/HF) ratio, which indicates decreased sympathetic nervous activity. Additionally, (4) according to subjective evaluations, the participants perceived themselves as being more "comfortable," "relaxed," "natural," "warm," "uneven," "dry," and "soft" after touching Hinoki. Thus, our cumulative findings indicate that touching Hinoki with the soles of the feet induces physiological relaxation. PMID- 30274161 TI - An Adaptive Zero Velocity Detection Algorithm Based on Multi-Sensor Fusion for a Pedestrian Navigation System. AB - The zero velocity update (ZUPT) algorithm is an effective way to suppress the error growth for a foot-mounted pedestrian navigation system. To make ZUPT work properly, it is necessary to detect zero velocity intervals correctly. Existing zero velocity detection methods cannot provide good performance at high gait speeds or stair climbing. An adaptive zero velocity detection approach based on multi-sensor fusion is proposed in this paper. The measurements of an accelerometer, gyroscope and pressure sensor were employed to construct a zero velocity detector. Then, the adaptive threshold was proposed to improve the accuracy of the detector under various motion modes. In addition, to eliminate the height drift, a stairs recognition method was developed to distinguish staircase movement from level walking. Detection performance was examined with experimental data collected at varying motion modes in real scenarios. The experimental results indicate that the proposed method can correctly detect zero velocity intervals under various motion modes. PMID- 30274162 TI - Aqueous Synthesis, Degradation, and Encapsulation of Copper Nanowires for Transparent Electrodes. AB - Copper nanowires (CuNWs) have increasingly become subjected to academic and industrial research, which is attributed to their good performance as a transparent electrode (TE) material that competes with the one of indium tin oxide (ITO). Recently, an environmentally friendly and aqueous synthesis of CuNWs was demonstrated, without the use of hydrazine that is known for its unfavorable properties. In this work, we extend the current knowledge for the aqueous synthesis of CuNWs by studying their up-scaling potential. This potential is an important aspect for the commercialization and further development of CuNW-based devices. Due to the scalability and homogeneity of the deposition process, spray coating was selected to produce films with a low sheet resistance of 7.6 Omega/sq. and an optical transmittance of 77%, at a wavelength of 550 nm. Further, we present a comprehensive investigation of the degradation of CuNWs when subjected to different environmental stresses such as the exposure to ambient air, elevated temperatures, high electrical currents, moisture or ultraviolet (UV) light. For the oxidation process, a model is derived to describe the dependence of the breakdown time with the temperature and the initial resistance. Finally, polymer coatings made of polydimethylsiloxane (PDMS) and polymethylmethacrylate (PMMA), as well as oxide coatings composed of electron beam evaporated silicon dioxide (SiO2) and aluminum oxide (Al2O3) are tested to hinder the oxidation of the CuNW films under current flow. PMID- 30274165 TI - Polarimetric-Phase-Enhanced Intensity Interrogation Scheme for Surface Wave Optical Sensors with Low Optical Loss. AB - A polarimetric-phase-enhanced intensity interrogation scheme leveraging the polarization-dependent sharp phase change induced by the surface wave excitation at a low-optical-loss sensor's surface is proposed and experimentally demonstrated. Based on a simple setup with no moving parts during interrogation, a polarimetric-phase-enhanced intensity can be obtained by subtracting the reflected intensities of two beam polarization states. Our results show a ~4-fold sensitivity increase compared to traditional intensity detection schemes for similar sensors. As novel surface wave optical sensors are designed and engineered with optimized phase responses, this scheme offers a low-complexity solution for such devices instead of traditional phase interrogation schemes. PMID- 30274164 TI - Acute Kidney Injury Definition and Diagnosis: A Narrative Review. AB - Acute kidney injury (AKI) is a complex syndrome characterized by a decrease in renal function and associated with numerous etiologies and pathophysiological mechanisms. It is a common diagnosis in hospitalized patients, with increasing incidence in recent decades, and associated with poorer short- and long-term outcomes and increased health care costs. Considering its impact on patient prognosis, research has focused on methods to assess patients at risk of developing AKI and diagnose subclinical AKI, as well as prevention and treatment strategies, for which an understanding of the epidemiology of AKI is crucial. In this review, we discuss the evolving definition and classification of AKI, and novel diagnostic methods. PMID- 30274166 TI - Enhancing Multiple Jets in Electrospinning: The Role of Auxiliary Electrode. AB - An auxiliary electrode introduced in traditional spinneret electrospinning is an effective and powerful technique to improve the production rate of nanofibers. In this work, the effects of the arrangement of auxiliary electrode, applied voltage, injection speed, and the distance between the electrode tip and the spinneret tip (ESD) on the jet number and the morphology of polyvinyl alcohol (PVA) nanofibers were investigated systematically. The results showed that the number of jets firstly increased and then decreased with the increase of applied voltage and ESD, respectively, while increasing with the injection speed in both the auxiliary electrode in the vertical position and parallel position. The average nanofiber diameter decreased with increasing of applied voltage and injection speed, but decreasing in ESD in these two positions. The numerical simulation results revealed that the auxiliary electrode primarily influenced the electric field intensity in the spinning area. This work provides a deep understanding of multiple jets in electrospinning. PMID- 30274163 TI - Adverse Childhood Experiences in Children with Intellectual Disabilities: An Exploratory Case-File Study in Dutch Residential Care. AB - Adverse Childhood Experiences (ACEs) are negative childhood events occurring in a child's family or social environment, that may cause harm or distress. Children with intellectual disabilities (ID) and their families are underrepresented in international ACEs research, while current insights can also contribute to the improvement of their health and well-being. Deficiencies in intellectual and adaptive functioning and living circumstances can increase their vulnerability to adversities. In the present exploratory study 69 case-files of children referred to a Dutch national center for residential youth care for children with ID were analyzed to assess the prevalence and associations of ACEs. It was found that almost half (49.3%) of the children experienced 2 ACEs from the original ACEs framework or more (M (mean) = 2.1; SD (standard deviation) = 1.8) and that the number of ACEs in children was related to the presence of ACEs in parents. Both child and parental ACEs were also related to attachment- and trauma- and stressor related disorders. Finally, living circumstances and multiple ACEs from the expanded ACEs framework, especially related to parental characteristics, were found to be related to ACEs in children with ID. This implicates the importance of a transgenerational approach when further investigating the impact of ACEs on mental and physical health in children with ID (intellectual disabilities). PMID- 30274167 TI - Regulation of Macrophage Activation and Polarization by HCC-Derived Exosomal lncRNA TUC339. AB - Exosomes released by cells can serve as vehicles for delivery of biological materials and signals. Long non-coding RNAs (lncRNAs) are non-coding RNAs longer than 200 nt, which roles are increasingly appreciated in various biological content. Tumor-derived exosomal lncRNAs have been implicated as signaling mediators to orchestrate cell function among neighbor tumor cells. However, the role of tumor-derived lncRNAs in cross-talk with environmental macrophages has yet to be explored. In this paper, we demonstrated that hepatocellular carcinoma (HCC) cells-derived exosomes contain elevated levels of lncRNA TUC339 and that HCC-derived exosomes could be taken up by THP-1 cells. In seeking to dissect the biological function of tumor secreting TUC339 in macrophages, we applied loss-of function and gain-of-function strategies. We observed increased pro-inflammatory cytokine production, increased co-stimulatory molecule expression, and enhanced phagocytosis upon suppression of TUC339 by siRNA in THP-1 cells, and the opposite effect upon over-expression of this lncRNA, which indicates that TUC339 was involved in the regulation of macrophage activation. Moreover, we detected an elevated level of TUC339 in M(IL-4) macrophages as compared to M(IFN-gamma + LPS) macrophages and a down-regulation of TUC339 expression during M(IL-4)-to-M(IFN gamma + LPS) repolarization and vice versa. Furthermore, suppression of TUC339 in macrophages diminished the expression of M(IL-4) markers upon IL-4 treatment while overexpression of TUC339 in macrophages enhanced M(IL-4) markers upon IFN gamma + LPS treatment, which suggests a critical function of TUC339 in the regulation of macrophage M1/M2 polarization. Lastly, using microarray analysis, we identified cytokine-cytokine receptor interaction, CXCR chemokine receptor binding, Toll-like receptor signaling, FcgammaR-mediated phagocytosis, regulation of the actin cytoskeleton, and cell proliferation are related with TUC339 function in macrophages. Our results provide evidence for a novel regulatory function of tumor-derived exosomal lncRNA TUC339 in environmental macrophages and shed light on the complicated interactions between tumor and immune cells through exosomal lncRNAs. PMID- 30274168 TI - Ectopic Overexpression of Porcine Myh1 Increased in Slow Muscle Fibers and Enhanced Endurance Exercise in Transgenic Mice. AB - Myosin heavy chain (MyHC) isoforms consist of Myh7, Myh2, Myh1, and Myh4, which are expressed in skeletal muscle tissues during postnatal development. These genes influence the contraction-relaxation activity in skeletal muscles and are involved in determining muscle composition such as the proportion of fast-to-slow and/or slow-to-fast fiber types. Among them, Myh1 is associated with skeletal muscle contraction and is involved in both slow-to-fast and fast-to-slow transition. However, the muscle transition mechanism is not well understood. For this study, we first produced porcine Myh1 transgenic (TG) mice to study whether the ectopic expressed porcine Myh1 gene had any effects on muscle composition, especially on slow-type muscle components. Our results showed that the factors associated with slow muscles, such as Myh7, Myoglobin, Troponin (slow-type units), and cytochrome C, were highly expressed in the quadriceps muscles of Myh1 transgenic mice. Furthermore, the ectopic porcine MYH1 protein was located only in the slow-type muscle fibers of the quadriceps muscles in Myh1 transgenic mice. In physical endurance tests, Myh1 transgenic mice ran longer and further on a treadmill than wild-type (WT) mice. These data fully supported our hypothesis that Myh1 is associated with slow muscle composition, with overexpression of Myh1 in muscle tissues possibly being a new key in modulating muscle fiber types. Our study provides a better understanding of muscle composition metabolism, physical mobility, and genetic factors in muscle fatigue. PMID- 30274169 TI - Reactivation of Latent Epstein-Barr Virus: A Comparison after Exposure to Gamma, Proton, Carbon, and Iron Radiation. AB - Among the many stressors astronauts are exposed to during spaceflight, cosmic radiation may lead to various serious health effects. Specifically, space radiation may contribute to decreased immunity, which has been documented in astronauts during short- and long-duration missions, as evidenced by several changes in cellular immunity and plasma cytokine levels. Reactivation of latent herpes viruses, either directly from radiation of latently infected cells and/or from perturbation of the immune system, may result in disease in astronauts. Epstein-Barr virus (EBV) is one of the eight human herpes viruses known to infect more than 90% of human adults and persists for the life of the host without normally causing adverse effects. Reactivation of several latent viruses in astronauts is well documented, although the mechanism of reactivation is not well understood. We studied the effect of four different types of radiation, (1) 137Cs gamma rays, (2) 150-MeV protons, (3) 600 MeV/n carbon ions, and (4) 600 MeV/n iron ions on the activation of lytic gene transcription and of reactivation of EBV in a latently infected cell line (Akata) at doses of 0.1, 0.5, 1.0, and 2.0 Gy. The data showed that for all doses used in this study, lytic gene transcription was induced and median viral loads were significantly higher for all types of radiation than in corresponding control samples, with the increases detected as early as four days post-exposure and generally tapering off at later time points. The viability and size of EBV-infected Akata cells were highly variable and exhibited approximately the same trend in time for all radiation types at 0.1, 0.5, 1.0, and 2.0 Gy. This work shows that reactivation of viruses can occur due to the effect of different types of radiation on latently infected cells in the absence of changes or cytokines produced in the immune system. In general, gamma rays are more effective than protons, carbon ions, and iron ions in inducing latent virus reactivation, though these high-energy particles did induce more sustained and later reactivation of EBV lytic gene transcription. These findings also challenge the common relative biological effectiveness concept that is often used in radiobiology for other end points. PMID- 30274170 TI - Mechanical Property Tests and Strength Formulas of Basalt Fiber Reinforced Recycled Aggregate Concrete. AB - In order to investigate the influence of basalt fibers (BFs) on the mechanical performance of recycled aggregate concrete (RAC), some groups of RAC specimens were first tested involving different types of fibers such as carbon fibers, steel fibers, polypropylene fibers and hybrid fibers. The main four indices for the investigation consisted of cube compressive strengths, axial compressive strengths, splitting tensile strengths and Young's modulus. The effects of fiber volume fractions on the RAC slumps were also discussed. Meanwhile, the mechanical properties and failure modes of the BF-reinforced RAC were compared with those of other fiber-reinforced RAC and common concrete (CC). Subsequently the optimal volume fractions of BFs were explored for different mechanical properties within the volume fraction range of 0-0.2%. The back propagation neural networks were further applied to predict and validate the optimal BF fractions. Lastly, the general strength formulas, as well as the elastic modulus formula, for BF reinforced RAC were deducted based on the specimen test results. It is found that the addition of fibers may improve the failure modes of RAC and different fibers present positive or negative effects on the mechanical properties. The optimal volume fractions of BF with respect to the four mechanical indices are 0.1%, 0.15%, 0.1% and 0.2% respectively. The proposed strength and elastic modulus formulas of BF-reinforced RAC provide satisfactory predictions with the test results and thus can be used as a reference in practice. PMID- 30274171 TI - The Influence of Bisphenol A (BPA) on Neuregulin 1-Like Immunoreactive Nerve Fibers in the Wall of Porcine Uterus. AB - Bisphenol A (BPA), a substance commonly used in the manufacture of plastics, shows multidirectional negative effects on humans and animals. Due to similarities to estrogens, BPA initially leads to disorders in the reproductive system. On the other hand, it is known that neuregulin 1 (NRG-1) is an active substance which enhances the survivability of cells, inhibits apoptosis, and protects tissues against damaging factors. Because the influence of BPA on the nervous system has also been described, the aim of the present study was to investigate for the first time the influence of various doses of BPA on neuregulin 1-like immunoreactive (NRG-1-LI) nerves located in the porcine uterus using the routine single- and double-immunofluorescence technique. The obtained results have shown that BPA increases the number and affects the neurochemical characterization of NRG-1-LI in the uterus, and changes are visible even under the impact of small doses of this toxin. The character of observed changes depended on the dose of BPA and the part of the uterus studied. These observations suggest that NRG-1 in nerves supplying the uterus may play roles in adaptive and protective mechanisms under the impact of BPA.

Toxins 2017, 10, 18-Quintessential Use of Ultrasound Guidance for Botulinum Toxin Injections-Muscle Innervation Zone Targeting Revisited. AB - Recently, the importance of targeting structures during botulinum neurotoxin applications has been discussed in a variety of disorders, including spasticity and dystonia. In this respect, the advantages of ultrasound imaging to traditional techniques have been emphasized. We would like underscore the importance of ultrasound guidance, with targeting innervation zone(s) of the over active muscles to achieve effective clinical outcomes. Additionally, we also clarify the difference between the terms-innervation zone (motor end plate) and motor point-which have been used by the authors as if they were the same. Further, we disagree with the authors about the intramuscular botulinum neurotoxin application techniques i.e., in-plane vs. out-of-plane whereby the former is, for sure, superior. PMID- 30274172 TI - Alterations in Gastric Mucosal Expression of Calcitonin Gene-Related Peptides, Vanilloid Receptors, and Heme Oxygenase-1 Mediate Gastroprotective Action of Carbon Monoxide against Ethanol-Induced Gastric Mucosal Lesions. AB - Carbon monoxide (CO) has been reported to contribute to the maintenance of gastric mucosal integrity, gastroprotection, and ulcer healing. However, involvement of transient receptor potential vanilloid receptor type 1 (TRPV1) located on afferent sensory fibers endings and sensory neuropeptide calcitonin gene-related peptide (CGRP) in CO-mediated gastroprotection against ethanol induced gastric damage has not been explored. Male Wistar rats with and without denervation of afferent sensory neurons induced by capsaicin (total dose 125 mg/kg within 3 days) were pretreated with vehicle, CO donor tricarbonyldichlororuthenium (II) dimer (CORM-2, 5 mg/kg i.g.), administered alone or with CGRP-alpha (10 MUg/kg i.p.) or TRPV1 antagonist capsazepine (5 mg/kg i.g.), followed 30 min later by intragastric (i.g.) administration of 75% ethanol. The area of gastric damage and gastric blood flow (GBF) were assessed planimetrically and by laser flowmetry, respectively. Microscopic evaluation of ethanol-induced gastric lesions was performed after haematoxylin/eosin (H&E) or alcian blue/periodic acid-Schiff/alcian blue (AB/PAS) staining. Gastric mucosal mRNA fold change for heme oxygenase (HMOX)-1, HMOX-2, CGRP-alpha, CGRP-beta, inducible nitric oxide synthase (iNOS), endothelial (e)NOS, neuronal (n)NOS, cyclooxygenase (COX)-1, COX-2, and protein expression for HMOX-1 and TRPV1 was determined by real-time PCR or Western blot, respectively. Pretreatment with CORM 2 combined or not with CGRP reduced ethanol-induced gastric lesions and elevated GBF. Capsaicin-denervation or co-treatment with capsazepine or CGRP and CORM-2 in capsaicin-denervated animals failed to affect these beneficial effects of CO donor. In rats with intact sensory nerves, CORM-2 increased gastric mRNA level for HMOX-1 and CGRP-alpha. In capsaicin-denervated rats, CORM-2 increased eNOS mRNA fold change and TRPV1 protein expression while capsaicin denervation itself decreased HMOX-1 protein expression and eNOS mRNA level. We conclude that CO prevents gastric mucosa from ethanol-induced lesions due to activation of TRPV1/CGRP-alpha system and accompanying increase in gastric microcirculation but independently on afferent sensory nerve activity despite the stimulation of TRPV1 protein and CGRP-alpha mRNA expression. PMID- 30274174 TI - Influence of Beam Offset on Dissimilar Laser Welding of Molybdenum to Titanium. AB - Dissimilar joining of molybdenum (Mo) to titanium (Ti) is of great significance to the design and fabrication of high-temperature facilities. However, few reports were found about fusion joining of these two metals. The objective of this paper is to assess the feasibility of laser beam welding (LBW) of 2 mm-thick molybdenum and titanium. The effects of laser beam offset on the laser dissimilar joint of pure molybdenum to pure titanium were analyzed in terms of microstructure, chemical composition, microhardness, and tensile behavior. The results showed that the weld appearance improved with the increase of the offset. The fusion zone was strengthened because of the solid solution of these two elements. The mechanical properties of samples increased firstly and then decreased with the increasing of offset. When the laser beam irradiated on the titanium plate and the center of the laser spot was 0.5 mm away from the Mo/Ti interface, the joint performed the highest tensile strength, which was about 70% that of titanium base metal. LBW was demonstrated to be a promising method to join dissimilar Mo/Ti joint. PMID- 30274175 TI - Hazardous Drinking among Students over a Decade of University Policy Change: Controlled Before-and-After Evaluation. AB - Background: Responding to high levels of alcohol-related harm among students, a New Zealand university deployed a security and liaison service, strengthened the Student Code of Conduct, increased its input on the operation of alcohol outlets near campus, and banned alcohol advertising on campus. We estimated the change in the prevalence of alcohol consumption patterns among students at the university compared with other universities. Methods: We conducted a controlled before-and after study with surveys in residential colleges at the target university in 2004 and 2014, and in random samples of students at the target university and three control universities in 2005 and 2013. The primary outcome was the prevalence of recent intoxication, while we analysed drinking per se and drinking in selected locations to investigate mechanisms of change. Results: The 7-day prevalence of intoxication decreased from 45% in 2004 to 33% in 2014 (absolute difference: 12%; 95% CI: 7% to 17%) among students living in residential colleges, and from 40% in 2005 to 26% in 2013 (absolute difference: 14%; 95% CI: 8% to 20%) in the wider student body of the intervention university. The intervention effect estimate, representing the change at the intervention university adjusted for change at other universities (aOR = 1.30; 95% CI: 0.89 to 1.90), was consistent with a benefit of intervention but was not statistically significant (p = 0.17). Conclusion: In this period of alcohol policy reform, drinking to intoxication decreased substantially in the targeted student population. Policy reforms and coincidental environmental changes may each have contributed to these reductions. PMID- 30274176 TI - Fenofibrate Interferes with the Diapedesis of Lung Adenocarcinoma Cells through the Interference with Cx43/EGF-Dependent Intercellular Signaling. AB - Extravasation of circulating cancer cells is regulated by the intercellular/intracellular signaling pathways that locally impair the endothelial barrier function. Co-cultures of human umbilical vein endothelial cells (HUVECs) with lung adenocarcinoma A549 cells enabled us to identify these pathways and to quantify the effect of fenofibrate (FF) on their activity. A549 cells induced the disruption and local activation of endothelial continuum. These events were accompanied by epidermal growth factor (EGF) up-regulation in endothelial cells. Impaired A549 diapedesis and HUVEC activation were seen upon the chemical inhibition of connexin(Cx)43 functions, EGF/ERK1/2-dependent signaling, and RhoA/Rac1 activity. A total of 25 MUM FF exerted corresponding effects on Cx43-mediated gap junctional coupling, EGF production, and ERK1/2 activation in HUVEC/A549 co-cultures. It also directly augmented endothelial barrier function via the interference with focal adhesion kinase (FAK)/RhoA/Rac1 regulated endothelial cell adhesion/contractility/motility and prompted the selective transmigration of epithelioid A549 cells. N-acetyl-L-cysteine abrogated FF effects on HUVEC activation, suggesting the involvement of PPARalpha independent mechanism(s) in its action. Our data identify a novel Cx43/EGF/ERK1/2/FAK/RhoA/Rac1-dependent signaling axis, which determines the efficiency of lung cancer cell diapedesis. FF interferes with its activity and reduces the susceptibility of endothelial cells to A549 stimuli. These findings provide the rationale for the implementation of FF in the therapy of malignant lung cancers. PMID- 30274178 TI - Can Aluminum Tolerant Wheat Cultivar Perform Better under Phosphate Deficient Conditions? AB - Low availability of inorganic phosphate (Pi), together with aluminum (Al), is a major constraint for plant growth and development in acidic soils. To investigate whether or not Al-resistant cultivars can perform better under Pi deficiency, we chose two wheat cultivars with different Al-responses-Atlas 66, being Al tolerant, and Scout 66, which is Al-sensitive-and analyzed their responses to Pi deficiency. Results showed that, unexpectedly, the Al-sensitive cultivar Scout 66 contained comparatively higher amount of soluble phosphate (Pi) and total phosphorus (P) both in the roots and in the shoots than Atlas 66 under P deficiency. In addition, Scout 66 exhibited higher root biomass, root volume, and root tip numbers, compared with Atlas 66. The expression of Pi-responsive marker genes, TaIPS1, TaSPX3, and TaSQD2 was strongly induced in both cultivars, but the extents of induction were higher in Scout 66 than in Atlas 66 under long-term Pi starvation. Taken together, our results suggest that the Al-sensitive cultivar Scout 66 performed much better under sole Pi starvation, which sets the following experimental stage to uncover the underlying mechanisms of why Scout 66 can display better under Pi deficiency. Our study also raises an open question whether Al-resistant plants are more sensitive to Pi deficiency. PMID- 30274177 TI - Multifunctional Cargo-Free Nanomedicine for Cancer Therapy. AB - Nanocarriers encapsulating multiple chemotherapeutics are a promising strategy to achieve combinational chemotherapy for cancer therapy; however, they generally use exotic new carriers without therapeutic effect, which usually suffer from carrier-related toxicity issues, as well as having to pass extensive clinical trials to be drug excipients before any clinical applications. Cargo-free nanomedicines, which are fabricated by drugs themselves without new excipients and possess nanoscale characteristics to realize favorable pharmacokinetics and intracellular delivery, have been rapidly developed and drawn much attention to cancer treatment. Herein, we discuss recent advances of cargo-free nanomedicines for cancer treatment. After a brief introduction to the major types of carrier free nanomedicine, some representative applications of these cargo-free nanomedicines are discussed, including combination therapy, immunotherapy, as well as self-monitoring of drug release. More importantly, this review draws a brief conclusion and discusses the future challenges of cargo-free nanomedicines from our perspective. PMID- 30274179 TI - Lysine Acetylation Regulates Alanyl-tRNA Synthetase Activity in Escherichia coli. AB - Protein lysine acetylation is a widely conserved posttranslational modification in all three domains of life. Lysine acetylation frequently occurs in aminoacyl tRNA synthetases (aaRSs) from many organisms. In this study, we determined the impact of the naturally occurring acetylation at lysine-73 (K73) in Escherichia coli class II alanyl-tRNA synthetase (AlaRS) on its alanylation activity. We prepared an AlaRS K73Ac variant in which Nepsilon-acetyl-l-lysine was incorporated at position 73 using an expanded genetic code system in E. coli. The AlaRS K73Ac variant showed low activity compared to the AlaRS wild type (WT). Nicotinamide treatment or CobB-deletion in an E. coli led to elevated acetylation levels of AlaRS K73Ac and strongly reduced alanylation activities. We assumed that alanylation by AlaRS is affected by K73 acetylation, and the modification is sensitive to CobB deacetylase in vivo. We also showed that E. coli expresses two CobB isoforms (CobB-L and CobB-S) in vivo. CobB-S displayed the deacetylase activity of the AlaRS K73Ac variant in vitro. Our results imply a potential regulatory role for lysine acetylation in controlling the activity of aaRSs and protein synthesis. PMID- 30274180 TI - Recent Advances in Shiga Toxin-Producing Escherichia coli Research in Latin America. AB - Pathogenic Escherichia coli are known to be a common cause of diarrheal disease and a frequently occurring bacterial infection in children and adults in Latin America. Despite the effort to combat diarrheal infections, the south of the American continent remains a hot spot for infections and sequelae associated with the acquisition of one category of pathogenic E. coli, the Shiga toxin-producing E. coli (STEC). This review will focus on an overview of the prevalence of different STEC serotypes in human, animals and food products, focusing on recent reports from Latin America outlining the recent research progress achieved in this region to combat disease and endemicity in affected countries and to improve understanding on emerging serotypes and their virulence factors. Furthermore, this review will highlight the progress done in vaccine development and treatment and will also discuss the effort of the Latin American investigators to respond to the thread of STEC infections by establishing a multidisciplinary network of experts that are addressing STEC-associated animal, human and environmental health issues, while trying to reduce human disease. Regardless of the significant scientific contributions to understand and combat STEC infections worldwide, many significant challenges still exist and this review has focus in the Latin American efforts as an example of what can be accomplished when multiple groups have a common goal. PMID- 30274181 TI - An Optimized Relay Selection Technique to Improve the Communication Reliability in Wireless Sensor Networks. AB - Wireless Sensor Networks (WSN) are enabler technologies for the implementation of the Internet of Things (IoT) concept. WSNs provide an adequate infrastructure for the last-link communication with smart objects. Nevertheless, the wireless communication medium being inherently unreliable, there is the need to increase its communication reliability. Techniques based on the use of cooperative communication concepts are one of the ways to achieve this target. Within cooperative communication techniques, nodes selected as relays transmit not only their own data, but also cooperate by retransmitting data from other nodes. A fundamental step to improve the communication reliability of WSNs is related to the use of efficient relay selection techniques. This paper proposes a relay selection technique based on multiple criteria to select the smallest number of relay nodes and, at the same time, to ensure an adequate operation of the network. Additionally, two relay updating schemes are also investigated, defining periodic and adaptive updating policies. The simulation results show that both proposed schemes, named Periodic Relay Selection and Adaptive Relay Selection, significantly improve the communication reliability of the network, when compared to other state-of-the-art relay selection schemes. PMID- 30274182 TI - Research on a Mixed Gas Recognition and Concentration Detection Algorithm Based on a Metal Oxide Semiconductor Olfactory System Sensor Array. AB - As a typical machine olfactory system index, the accuracy of hybrid gas identification and concentration detection is low. This paper proposes a novel hybrid gas identification and concentration detection method. In this method, Kernel Principal Component Analysis (KPCA) is employed to extract the nonlinear mixed gas characteristics of different components, and then K-nearest neighbour algorithm (KNN) classification modelling is utilized to realize the recognition of the target gas. In addition, this method adopts a multivariable relevance vector machine (MVRVM) to regress the multi-input nonlinear signal to realize the detection of the concentration of the hybrid gas. The proposed method is validated by using CO and CH4 as the experimental system samples. The experimental results illustrate that the accuracy of the proposed method reaches 98.33%, which is 5.83% and 14.16% higher than that of principal component analysis (PCA) and independent component analysis (ICA), respectively. For the hybrid gas concentration detection method, the CO and CH4 concentration detection average relative errors are reduced to 5.58% and 5.38%, respectively. PMID- 30274185 TI - Serum VEGF Level Is Different in Adolescents Smoking Waterpipe versus Cigarettes: The Irbid TRY. AB - Waterpipe (Wp) use is associated with most devastating diseases and particularly popular among adolescents. Vascular endothelium growth factor (VEGF) is essential for generating new vessels. The effect of smoking tobacco on VEGF is controversial and unknown among adolescents. Therefore, the current study compared serum VEGF in adolescents smoking cigarettes (Cg) only (9.3%), Wp only (19.6%), and dual (Wp and Cg) (36.4%) versus nonsmokers (34.6%) in adolescents. A self-reported questionnaire and enzyme-linked immunosorbent assay (ELISA) were used to obtain smoking status and serum VEGF, respectively, in 475 (age: 14.6 +/- 1.0 years) boys (n = 263) and girls (n = 212) from Irbid, Jordan. The analysis showed that smoking status (R2 = 0.021; p = 0.001) and gender (R2 = 0.035; p = 0.000) can predict VEGF. Furthermore, 2-way-ANCOVA revealed that VEGF was lower in the dual cohort versus the Cg (33.4%; p = 0.04) and nonsmoker (29.6%; p = 0.003) cohorts; VEGF in smokers, was lower (33.6%; p = 0.04) in the Wp versus nonsmokers in the boys but not the girls. These results are unique and suggest that smoking lowers VEGF, which might adversely affect vascular growth and function. This is alarming given that adolescents are still in the development stage and smoking, particularly Wp, is popular among them. Therefore, interventions targeting smoking among schoolchildren are urgently needed to avoid the negative effects of smoking, especially on vascular health. PMID- 30274184 TI - Influence of Luting Materials on the Retention of Cemented Implant-Supported Crowns: An In Vitro Study. AB - The retention force of cemented crowns on implant abutments with various luting materials was evaluated. Cobalt-chromium crowns were cemented onto tapered titanium abutments (Camlog) with eugenol-free temporary cement (RelyX TempBond NE), composite-based temporary cement (Bifix Temp), zinc phosphate cement (Harvard Cement), glass-ionomer cements (Meron, Fuji I), and resin-modified glass ionomer cements (Fuji II, Fuji Plus, Ketac Cem Plus). Specimen aging via hydrostress was performed in artificial saliva at 37 degrees C for 14 days (S1), followed by hydrothermal stress with thermocycling (S2). The crowns were removed, and the force was recorded (T1). Subsequently, the crowns were recemented, aged, and removed, and the force was recorded (T2, T3). The retention forces differences were statistically significant according to the storage conditions at T1 (p = 0.002) and T3 (p = 0.0002). After aging (S1), Ketac Cem Plus had the highest retention force median value difference (T3 versus T1) (-773 N), whereas RelyX TempBond NE had the lowest (-146 N). After aging (S2), Meron had the highest retention force median value difference (-783 N), whereas RelyX TempBond NE had the lowest (-168 N). Recementation decreased the retention force of the implant-supported cobalt-chromium crowns cemented and recemented with the same luting materials. Luting materials (at T1) and aging conditions significantly impacted the retention force. PMID- 30274183 TI - Sensitization of Cancer Cells to Radiation and Topoisomerase I Inhibitor Camptothecin Using Inhibitors of PARP and Other Signaling Molecules. AB - Radiation and certain anticancer drugs damage DNA, resulting in apoptosis induction in cancer cells. Currently, the major limitations on the efficacy of such therapies are development of resistance and adverse side effects. Sensitization is an important strategy for increasing therapeutic efficacy while minimizing adverse effects. In this manuscript, we review possible sensitization strategies for radiation and anticancer drugs that cause DNA damage, focusing especially on modulation of damage repair pathways and the associated reactions. PMID- 30274186 TI - Bitumen Foaming Optimisation Process on the Basis of Rheological Properties. AB - This article discusses the results of bitumen foam properties optimisation with respect to three factors: air pressure, bitumen temperature and amount of water. The test materials were unmodified bitumen 50/70 and bitumen 50/70 modified with 2.5% synthetic wax. The experiment was designed according to the 3(3-1) fractional factorial design. The distribution of parameters of bitumen foam were measured with the authors' original apparatus using a laser beam. This measurement method increased the accuracy of maximum expansion ratio (ER) and half-life (HL) estimation. Based on HL and ER results, it was found that the foaming process increased bitumen stiffness due to the dynamic ageing of the bitumen. The experimental design allows more effective control over the properties of foamed bitumen with respect to its intended use. The presence of synthetic wax extended the half-life of the bitumen foam. PMID- 30274187 TI - GesID: 3D Gesture Authentication Based on Depth Camera and One-Class Classification. AB - Biometric authentication is popular in authentication systems, and gesture as a carrier of behavior characteristics has the advantages of being difficult to imitate and containing abundant information. This research aims to use three dimensional (3D) depth information of gesture movement to perform authentication with less user effort. We propose an approach based on depth cameras, which satisfies three requirements: Can authenticate from a single, customized gesture; achieves high accuracy without an excessive number of gestures for training; and continues learning the gesture during use of the system. To satisfy these requirements respectively: We use a sparse autoencoder to memorize the single gesture; we employ data augmentation technology to solve the problem of insufficient data; and we use incremental learning technology for allowing the system to memorize the gesture incrementally over time. An experiment has been performed on different gestures in different user situations that demonstrates the accuracy of one-class classification (OCC), and proves the effectiveness and reliability of the approach. Gesture authentication based on 3D depth cameras could be achieved with reduced user effort. PMID- 30274188 TI - Efficient Computation of Free Energy Surfaces of Diels-Alder Reactions in Explicit Solvent at Ab Initio QM/MM Level. AB - For Diels-Alder (DA) reactions in solution, an accurate and converged free energy (FE) surface at ab initio (ai) quantum mechanical/molecular mechanical (QM/MM) level is imperative for the understanding of reaction mechanism. However, this computation is still far too expensive. In a previous work, we proposed a new method termed MBAR+wTP, with which the computation of the ai FE profile can be accelerated by several orders of magnitude via a three-step procedure: (I) an umbrella sampling (US) using a semi-empirical (SE) QM/MM Hamiltonian is performed; (II) the FE profile is generated using the Multistate Bennett Acceptance Ratio (MBAR) analysis; and (III) a weighted Thermodynamic Perturbation (wTP) from the SE Hamiltonian to the ai Hamiltonian is performed to obtain the ai QM/MM FE profile using weight factors from the MBAR analysis. In this work, this method is extended to the calculations of two-dimensional FE surfaces of two Diels-Alder reactions of cyclopentadiene with either acrylonitrile or 1-4 naphthoquinone at ai QM/MM level. The accurate activation free energies at the ai QM/MM level, which are much closer to the experimental measurements than those calculated by other methods, indicate that this MBAR+wTP method can be applied in the studies of complex reactions in condensed phase with much-enhanced efficiency. PMID- 30274189 TI - Genetic Variation and Alleviation of Salinity Stress in Barley (Hordeum vulgare L.). AB - Barley (Hordeum vulgare L.) represents one of the most important cereals cultivated worldwide. Investigating genetic variability and structure of barley is important for enhancing the crop productivity. This study aimed to investigate the diversity and structure of 40 barley genotypes originated from three European countries (France, the Netherlands, Poland) using amplified fragment length polymorphisms (AFLPs). It also aimed to study 5-aminolevulinic acid (ALA) effect on salinity tolerance of six barley genotypes. The expected heterozygosity (He) diverged from 0.126 to 0.501, with a mean of 0.348. Polymorphic information content (PIC) diverged from 0.103 to 0.482 across barley genotypes, with a mean of 0.316, indicating that barley genotypes are rich in a considerable level of genetic diversity. The 40 barley genotypes were further studied based on their geographical origin (Western Europe and Eastern Europe). The Eastern European region (Poland) has a higher barley variability than the Western European region (France and the Netherlands). Nei's distance-based cluster tree divided the 40 barley accessions into two major clusters; one cluster comprised all the varieties originated from the Eastern European region, while the other major cluster included all accessions originated from the Western European region. Structure analysis results were in a complete concordance with our cluster analysis results. Slaski 2, Damseaux and Urbanowicki genotypes have the highest diversity level, whereas Carmen, Bigo and Cambrinus genotypes have the lowest level. The response of these six varieties to NaCl stress was also investigated. Salt stress (100 mM NaCl) slightly decreased levels of chlorophyll, carotenoid and osmolytes (proteins, soluble sugars, phenolics and flavonoids) in the leaves of Slaski 2, Damseaux and Urbanowicki genotypes at non-significant level, as compared to control samples. However, pigment contents and osmolytes in leaves of Carmen, Bigo and Cambrinus genotypes were significantly decreased by salt stress. Antioxidant enzyme activities were significantly increased in Slaski 2 genotype, but non-significantly increased in Carmen by salt stress. Priming Slaski 2 and Carmen cultivars with ALA under salt stress significantly induced pigment contents, antioxidants enzymes activity and stress-responsive genes expression, relative to NaCl-stressed plants. In conclusion, this study suggested a correlation between variability percentage and degree of salinity resistance. ALA improved salt tolerance in barley. PMID- 30274190 TI - Crystal Plasticity Modeling of Anisotropic Hardening and Texture Due to Dislocation Transmutation in Twinning. AB - In crystalline materials, dislocations are three-dimensional lattice distortions that systematically distort twin interfaces that they encounter. This results in dislocation dissociation events and changes in the atomic structure of the interface. The manner in which the interface distorts drive the product of the dissociation event, and consequently, the incident dislocation core and the magnitude and relative direction of the Burgers vector govern these slip-twin interaction phenomena. Recent characterization studies using transmission electron microscopy as well as advanced molecular dynamic simulations have shown that slip dislocations, whether striking or struck by a {10 1 - 2} twin boundary, dissociate into a combination of twinning disconnections, interfacial disclinations (facets), jogs, and other types of dislocations engulfed inside the twin domains, called transmuted dislocations. While twinning disconnections were found to promote twin propagation, the dislocations incorporated inside the twin are of considerable importance to hardening and damage initiation as they more significantly obstruct slip dislocations accommodating plasticity of the twins. In this work, the dislocation transmutation event and its effect on hardening is captured using a dislocation density based hardening model contained in a visco plastic self-consistent mean-field model. This is done by allowing the twins to increase their dislocation densities, not only by virtue of slip inside the twin, but also through dislocations that transmute from the parents as the twin volume fraction increases. A correspondence matrix rule is used to determine the type of converted dislocations while tracking and parameterizing their evolution. This hypothesis provides a modeling framework for capturing slip-twin interactions. The model is used to simulate the mechanical response of pure Mg and provides a more physically based approach for modeling stress-strain behavior. PMID- 30274191 TI - Damage Detection of Concrete-Filled Square Steel Tube (CFSST) Column Joints under Cyclic Loading Using Piezoceramic Transducers. AB - Concrete-filled square steel tube column (CFSSTC) joints are the most important parts of concrete-filled steel tube frame structures. It is of great significance to study the damage of CFSSTC joints under the seismic loads. In this paper, embedded piezoceramic transducers are used to monitor the damage of core concrete of CFSSTC joints under cyclic loading and surface-bonded piezoceramic disks are used to monitor the debonding damage of the steel tube and core concrete of two specimens. The damages of the joints under different loading levels and different loading cycles are evaluated by the received signal of the piezoceramic transducers. The experimental results show that the amplitude of the signal attenuates obviously with the appearance of damage in the joints, and the degree of attenuation increases with the development of the damage. The monitoring results from piezoceramic transducers are basically consistent with the hysteresis loops and skeleton curves of the CFSSTC joints during the cyclic loading. The effectiveness of the piezoceramic transducers are verified by the experimental results in structural health monitoring of the CFSSTC joint under cyclic loading. PMID- 30274192 TI - Galgeun-tang Attenuates Cigarette Smoke and Lipopolysaccharide Induced Pulmonary Inflammation via IkappaBalpha/NF-kappaB Signaling. AB - Galgeun-tang water extract (GGWE) is used to treat various diseases such as the common cold, eczema and asthma in China and Korea. In this study, we investigated the anti-inflammatory effect of GGWE using a cigarette smoke (CS)- and lipopolysaccharide (LPS)-induced induced pulmonary inflammation mouse model. The mice were exposed to CS for a total of seven days (eight cigarettes per day for 1 h) and LPS was administered intranasally to mice on day 4. GGWE was administered by oral gavage at doses of 50 mg/kg or 100 mg/kg 1 h before exposure to CS. GGWE decreased inflammatory cell counts, and expression of inflammatory cytokines such as interleukin (IL)-6 and tumor necrosis factor alpha (TNF-alpha) in bronchoalveolar lavage fluid (BALF) from mice exposed to CS and LPS. GGWE reduced the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), as well as the phosphorylation of inhibitor of kappa-B subunit alpha (IkappaBalpha) and nuclear factor kappa-B (NF-kappaB) in CS- and LPS-exposed mice. Histological examinations revealed that GGWE suppressed inflammatory cell infiltration into lung tissue compared to untreated CS- and LPS-exposed mice. In conclusion, GGWE effectively suppressed CS- and LPS-induced pulmonary inflammation. Our results indicate that GGWE may be used as a protective drug to control pulmonary inflammation diseases such as chronic obstructive pulmonary disease. PMID- 30274194 TI - Enhancing the Isolation and Performance of Control Planes for Fog Computing. AB - Fog computing, which places computing resources close to IoT devices, can offer low latency data processing for IoT applications. With software-defined networking (SDN), fog computing can enable network control logics to become programmable and run on a decoupled control plane, rather than on a physical switch. Therefore, network switches are controlled via the control plane. However, existing control planes have limitations in providing isolation and high performance, which are crucial to support multi-tenancy and scalability in fog computing. In this paper, we present optimization techniques for Linux to provide isolation and high performance for the control plane of SDN. The new techniques are (1) separate execution environment (SE2), which separates the execution environments between multiple control planes, and (2) separate packet processing (SP2), which reduces the complexity of the existing network stack in Linux. We evaluate the proposed techniques on commodity hardware and show that the maximum performance of a control plane increases by four times compared to the native Linux while providing strong isolation. PMID- 30274193 TI - Diet-Modulated Lipoprotein Metabolism and Vascular Inflammation Evaluated by 18F fluorodeoxyglucose Positron Emission Tomography. AB - Vascular inflammation plays a central role in atherosclerosis, from initiation and progression to acute thrombotic complications. Modified low-density lipoproteins (LDLs) and apoB-containing particles stimulate plaque inflammation by interacting with macrophages. Loss of function of high-density lipoprotein (HDL) for preventing LDL particles from oxidative modification in dyslipidemic states may amplify modified LDL actions, accelerating plaque inflammation. Diets are one of the most important factors that can affect these processes of lipoprotein oxidation and vascular inflammation. Recently, 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) has emerged as a reliable noninvasive imaging modality for identifying and quantifying vascular inflammation within atherosclerotic lesions based on the high glycolytic activity of macrophages infiltrating active atherosclerotic plaques. Vascular inflammation evaluated by FDG PET has been positively related to metabolic syndrome components and traditional risk factors of cardiovascular disease, including high-sensitivity C reactive protein, body mass index, and insulin resistance. A positive association of vascular inflammation with endothelial dysfunction, resistin levels, pericardial adipose tissue, and visceral fat area has also been reported. In contrast, HDL cholesterol and adiponectin have been inversely related to vascular inflammation detected by FDG PET. Because of its reproducibility, serial FDG PET shows potential for tracking the effects of dietary interventions and other systemic and local antiatherosclerotic therapies for plaque inflammation. PMID- 30274195 TI - Biocompatible Fe-Based Micropore Metal-Organic Frameworks as Sustained-Release Anticancer Drug Carriers. AB - Sustained-release preparation is a hot spot in antitumor drug research, where the first task is to select suitable drug carriers. Research has revealed that carboxylic acid iron metal-organic frameworks (MOFs), constructed from iron (Fe) ions and terephthalic acid, are nontoxic and biocompatible. Due to the breathing effect, the skeleton of this mesoporous material is flexible and can reversibly adapt its pore size through drug adsorption. Therefore, we chose one kind of Fe MOF, MIL-53(Fe), as a carrier for the anticancer drug oridonin (Ori). In this work, we report the design and synthesis of MIL-53(Fe) and explore its ability as a transport vehicle to deliver Ori. MIL-53(Fe) is characterized by scanning electron microscopy and X-ray powder diffraction. A loading capacity of 56.25 wt % was measured by high performance liquid chromatography. This carrier was safe and nontoxic (cell viability > 95.27%), depending on the results of 3-(4,5 dimethylthiazol-2-yl)--2,5-diphenyltetrazolium bromide assays, lactate dehydrogenase assays, and Annexin V-fluoresce isothiocyanate/propidium iodide double-staining assays. After loading the drug, the structure of the MIL-53(Fe) was not destroyed, and Ori was amorphous in MIL-53(Fe). Based on an analysis of the Ori release profile, results suggest that it lasts for more than seven days in vitro. The cumulative release rate of Ori at the seventh day was about 82.23% and 91.75% in phosphate buffer saline solution at 37 degrees C under pH 7.2 and pH 5.5, respectively. HepG2 cells were chosen to study the cytotoxicity of Ori@MIL-53(Fe), and the results show that the anticancer ratio of Ori@MIL-53(Fe) system reaches 90.62%. Thus, MIL-53 can be used as a carrier for anticancer drugs and Ori@MIL-53(Fe) is a promising sustained-release drug delivery system for the cancer therapy. PMID- 30274196 TI - Negative Air Ions and Their Effects on Human Health and Air Quality Improvement. AB - Negative air ions (NAIs) have been discovered for more than 100 years and are widely used for air cleaning. Here, we have carried out a comprehensive reviewing on the effects of NAIs on humans/animals, and microorganisms, and plant development. The presence of NAIs is credited for increasing psychological health, productivity, and overall well-being but without consistent or reliable evidence in therapeutic effects and with controversy in anti-microorganisms. Reports also showed that NAIs could help people in relieving symptoms of allergies to dust, mold spores, and other allergens. Particulate matter (PM) is a major air pollutant that affects human health. Experimental data showed that NAIs could be used to high-efficiently remove PM. Finally, we have reviewed the plant based NAI release system under the pulsed electric field (PEF) stimulation. This is a new NAI generation system which releases a huge amount of NAIs under the PEF treatment. The system may be used to freshen indoor air and reduce PM concentration in addition to enriching oxygen content and indoor decoration at home, school, hospital, airport, and other indoor areas. PMID- 30274197 TI - Inhibitory Effects of Intranasal Administration of Insulin on Fat Oxidation during Exercise Are Diminished in Young Overweight Individuals. AB - It remains unknown whether the high insulin (INS) levels in the brain affect fat oxidation during exercise. We examined the effects of the intranasal administration of INS, which increases the INS concentration in the cerebrospinal fluid when peripheral effects are lacking, on the maximum fat oxidation rate (maxFOR) and its intensity (FATmax) during exercise in 15 young normal-weight (N group) and eight young overweight (O group) individuals. On two separate days, either INS or placebo (PL) was randomly administered intranasally before a graded exercise test. Indirect calorimetry was used to assess maxFOR and FATmax during exercise. Blood INS and glucose levels did not change after INS administration. In the N group, maxFOR and FATmax were significantly smaller in the INS trial than in the PL trial. MaxFOR was significantly smaller in the O group than in the N group and was not influenced by INS administration. Exercise-induced elevation in blood epinephrine levels tended to be reduced by INS administration only in the N group. Intranasal INS administration reduces fat oxidation during exercise without any peripheral effects, possibly by suppressing sympathetic nerve activity. This inhibitory effect is diminished in overweight subjects, suggesting that cerebral insulin effects are attenuated in this population. PMID- 30274200 TI - Impact of Consumption of Bananas on Attraction of Anopheles stephensi to Humans. AB - Humans vary in attractiveness to mosquitoes, a phenomenon that is largely attributed to differences in physical cues such as heat and volatile odors emanating from breath and skin. Diet can change human odors but whether specific dietary components alter host attractiveness is largely unexplored. We identified bananas as a target for study following a survey of the internet for advice on avoiding mosquito bites. Human attractiveness to Anopheles stephensi Liston was measured using a glass vial bioassay where mosquito contacts were measured before and 1-3 h after ingestion of bananas or grapes. Consumption of grapes had no effect on the number of contacts but banana ingestion resulted in a significant increase in the overall number of contacts in spite of individual variation that included some subjects who showed no effect or decreases in contacts. Further tests with a single volunteer showed that the effect was repeatable and consistent across 15 trials. The magnitude of the increase was not affected by the number of bananas eaten. Increased contact counts after banana ingestion were also observed when A. gambiae Giles was tested. These results support the hypothesis that diet plays an important role in mediating host attractiveness to anopheline mosquitoes. PMID- 30274198 TI - Quantitative Proteomics Analysis of Lettuce (Lactuca sativa L.) Reveals Molecular Basis-Associated Auxin and Photosynthesis with Bolting Induced by High Temperature. AB - Bolting is a key process in the growth and development of lettuce (Lactuca sativa L.). A high temperature can induce early bolting, which decreases both the quality and production of lettuce. However, knowledge of underlying lettuce bolting is still lacking. To better understand the molecular basis of bolting, a comparative proteomics analysis was conducted on lettuce stems, during the bolting period induced by a high temperature (33 degrees C) and a control temperature (20 degrees C) using iTRAQ-based proteomics, phenotypic measures, and biological verifications using qRT-PCR and Western blot. The high temperature induced lettuce bolting, while the control temperature did not. Of the 5454 identified proteins, 619 proteins presented differential abundance induced by high-temperature relative to the control group, of which 345 had an increased abundance and 274 had a decreased abundance. Proteins with an abundance level change were mainly enriched in pathways associated with photosynthesis and tryptophan metabolism involved in auxin (IAA) biosynthesis. Moreover, among the proteins with differential abundance, proteins associated with photosynthesis and tryptophan metabolism were increased. These findings indicate that a high temperature enhances the function of photosynthesis and IAA biosynthesis to promote the process of bolting, which is in line with the physiology and transcription level of IAA metabolism. Our data provide a first comprehensive dataset for gaining novel understanding of the molecular basis underlying lettuce bolting induced by high temperature. It is potentially important for further functional analysis and genetic manipulation for molecular breeding to breed new cultivars of lettuce to restrain early bolting, which is vital for improving vegetable quality. PMID- 30274201 TI - Antimicrobial Coatings from Hybrid Nanoparticles of Biocompatible and Antimicrobial Polymers. AB - Hybrid nanoparticles of poly(methylmethacrylate) synthesized in the presence of poly (diallyldimethyl ammonium) chloride by emulsion polymerization exhibited good colloidal stability, physical properties, and antimicrobial activity but their synthesis yielded poor conversion. Here we create antimicrobial coatings from casting and drying of the nanoparticles dispersions onto model surfaces such as those of silicon wafers, glass coverslips, or polystyrene sheets and optimize conversion using additional stabilizers such as cetyltrimethyl ammonium bromide, dioctadecyldimethyl ammonium bromide, or soybean lecithin during nanoparticles synthesis. Methodology included dynamic light scattering, determination of wettability, ellipsometry of spin-coated films, scanning electron microscopy, and determination of colony forming unities (log CFU/mL) of bacteria after 1 h interaction with the coatings. The additional lipids and surfactants indeed improved nanoparticle synthesis, substantially increasing the conversion rates by stabilizing the monomer droplets in dispersion during the polymerization. The coatings obtained by spin-coating or casting of the nanoparticles dispersions onto silicon wafers were hydrophilic with contact angles increasing with the amount of the cationic polymer in the nanoparticles. Against Escherichia coli and Staphylococcus aureus, bacteria cell counts were reduced by approximately 7 logs upon interaction with the coatings, revealing their potential for several biotechnological and biomedical applications. PMID- 30274199 TI - Ocular Manifestations of Emerging Flaviviruses and the Blood-Retinal Barrier. AB - Despite flaviviruses remaining the leading cause of systemic human infections worldwide, ocular manifestations of these mosquito-transmitted viruses are considered relatively uncommon in part due to under-reporting. However, recent outbreaks of Zika virus (ZIKV) implicated in causing multiple ocular abnormalities, such as conjunctivitis, retinal hemorrhages, chorioretinal atrophy, posterior uveitis, optic neuritis, and maculopathies, has rejuvenated a significant interest in understanding the pathogenesis of flaviviruses, including ZIKV, in the eye. In this review, first, we summarize the current knowledge of the major flaviviruses (Dengue, West Nile, Yellow Fever, and Japanese Encephalitis) reported to cause ocular manifestations in humans with emphasis on recent ZIKV outbreaks. Second, being an immune privilege organ, the eye is protected from systemic infections by the presence of blood-retinal barriers (BRB). Hence, we discuss how flaviviruses modulate retinal innate response and breach the protective BRB to cause ocular or retinal pathology. Finally, we describe recently identified infection signatures of ZIKV and discuss whether these system biology-predicted genes or signaling pathways (e.g., cellular metabolism) could contribute to the pathogenesis of ocular manifestations and assist in the development of ocular antiviral therapies against ZIKV and other flaviviruses.

AB - Bee Bread samples from Romania and India were analysed by microscopy and High Performance Liquid Chromatography with Diode Array Detection (HPLC/DAD) and compared with pollen from the correspondent taxa. The quantification of sugars, fructose/glucose ratio, total phenolics and flavonoids was also carried out. From the results was possible to identify Brassica and Eucalyptus samples that present similar HPLC/DAD profiles with the respective ultraviolet (UV) identification of the main compounds as Kaempferol-3-O-glycosides and Hydrocinnamic acid derivatives. The Fructose/Glucose (F/G) ratio and the total amounts of phenolics and flavonoids was in line with the prevalence of the specie identified. These coincident fingerprints gave the identification of the samples, as was previously proposed for bee pollens. This paper relates for the first time the achievement on the taxon carried out previously only for bee pollens. It was reported for the first time that this phenolic profile remains unchanged in the case of floral pollen (hand collected), bee pollen and bee bread. Despite the biochemical transformation that occurs during the fermentation of bee bread, it seems that these phenolic compounds are not affected and remain unchanged. Also, variables such as soil and climate do not seem to influence these compounds for the kind of samples under study.

AB - The green alga Chlorella pyrenoidosa can accumulate lutein and chlorophyll under heterotrophic conditions. We propose that the mitochondrial respiratory electron transport chain (mRET) may be involved in this process. To verify this hypothesis, algal cells were treated with different mRET inhibitors. The biosynthesis of lutein and chlorophyll was found to be significantly stimulated by salicylhydroxamic acid (SHAM), whereas their contents substantially decreased after treatment with antimycin A and sodium azide (NaN3). Proteomic studies revealed profound protein alterations related to the redox and energy states, and a network was proposed: The up-regulation of peroxiredoxin reduces oxidized glutathione (GSSG) to reduced glutathione (GSH); phosphoenolpyruvate carboxykinase (PEPCK) catalyzes the conversion of oxaloacetic acid to phosphoenolpyruvate, and after entering the methylerythritol phosphate (MEP) pathway, 4-hydroxy-3-methylbut-2-en-1yl diphosphate synthase reduces 2-C-methyl-d erythritol-2,4-cyclodiphosphate (ME-Cpp) to 1-hydroxy-2-methyl-2-(E)-butenyl 4 diphosphate (HMBPP), which is closely related to the synthesis of lutein; and coproporphyrinogen III oxidase and ChlI play important roles in the chlorophyll biosynthetic pathway. These results supported that for the heterotrophic C. pyrenoidosa, the signaling, oriented from mRET, may regulate the nuclear genes encoding the enzymes involved in photosynthetic pigment biosynthesis. PMID- 30274205 TI - Are Early Warning Scores Useful Predictors for Mortality and Morbidity in Hospitalised Acutely Unwell Older Patients? A Systematic Review. AB - BACKGROUND: Early warning scores (EWSs) are used to identify deteriorating patients for appropriate interventions. We performed a systematic review to examine the usefulness of EWSs in predicting inpatient mortality and morbidity (transfer to higher-level care and length of hospital stay) in older people admitted to acute medical units with sepsis, acute cardiovascular events, or pneumonia. METHODS: A systematic review of published and unpublished databases was conducted. Cochrane's tool for assessing Risk of Bias in Non-Randomised Studies-of Interventions (ROBINS-I) was used to appraise the evidence. A narrative synthesis was performed due to substantial heterogeneity. RESULTS: Five studies (n = 12,057) were eligible from 1033 citations. There was an overall "moderate" risk of bias for all studies. The predictive ability of EWSs regarding mortality was reported in one study (n = 274), suggesting EWSs were better at predicting survival, (negative predictive value >90% for all scores). Three studies (n = 1819) demonstrated a significant association between increasing modified EWSs (MEWSs) and increased risk of mortality. Hazards ratios for a composite death/intensive care (ICU) admission with MEWSs >=5 were significant in one study (p = 0.003). Two studies (n = 1421) demonstrated that a MEWS >=6 was associated with 21 times higher probability of mortality (95% Confidence Interval (CI): 2.71-170.57) compared with a MEWS <=1. A MEWS of >=5 was associated with 22 times higher probability of mortality (95% CI: 10.45-49.16). CONCLUSION: Increasing EWSs are strongly associated with mortality and ICU admission in older acutely unwell patients. Future research should be targeted at better understanding the usefulness of high and increasing EWSs for specific acute illnesses in older adults.

AB - At present, sensor-based E-Healthcare systems are attracting more and more attention from academia and industry. E-Healthcare systems are usually a Wireless Body Area Network (WBANs), which can monitor or diagnose human health by placing miniaturized, low-power sensor nodes in or on patient's bodies to measure various physiological parameters. However, in this process, WBAN nodes usually use batteries, and especially for implantable flexible nodes, it is difficult to accomplish the battery replacement, so the energy that the node can carry is very limited, making the efficient use of energy the most important problem to consider when designing WBAN routing algorithms. By considering factors such as residual energy of node, the importance level of nodes, path cost and path energy difference ratios, this paper gives a definition of Optimal Path of Energy Consumption (OPEC) in WBANs, and designs the Optimal Energy Consumption routing based on Artificial Bee Colony (ABC) for WBANs (OEABC). A performance simulation is carried out to verify the effectiveness of the OEABC. Simulation results demonstrate that compared with the genetic algorithm and ant colony algorithm, the proposed OEABC has a better energy efficiency and faster convergence rate. PMID- 30274202 TI - Molecular Mechanisms of Hepatocarcinogenesis Following Sustained Virological Response in Patients with Chronic Hepatitis C Virus Infection. AB - Despite the success of direct-acting antiviral (DAA) agents in treating chronic hepatitis C virus (HCV) infection, the number of cases of HCV-related hepatocellular carcinoma (HCC) is expected to increase over the next five years. HCC develops over the span of decades and is closely associated with fibrosis stage. HCV both directly and indirectly establishes a pro-inflammatory environment favorable for viral replication. Repeated cycles of cell death and regeneration lead to genomic instability and loss of cell cycle control. DAA therapy offers >90% sustained virological response (SVR) rates with fewer side effects and restrictions than interferon. While elimination of HCV helps to restore liver function and reverse mild fibrosis, post-SVR patients remain at elevated risk of HCC. A series of studies reporting higher than expected rates of HCC development among DAA-treated patients ignited debate over whether use of DAAs elevates HCC risk compared to interferon. However, recent prospective and retrospective studies based on larger patient cohorts have found no significant difference in risk between DAA and interferon therapy once other factors are taken into account. Although many mechanisms and pathways involved in hepatocarcinogenesis have been elucidated, our understanding of drivers specific to post-SVR hepatocarcinogenesis is still limited, and lack of suitable in vivo and in vitro experimental systems has hampered efforts to examine etiology specific mechanisms that might serve to answer this question more thoroughly. Further research is needed to identify risk factors and biomarkers for post-SVR HCC and to develop targeted therapies based on more complete understanding of the molecules and pathways implicated in hepatocarcinogenesis. PMID- 30274208 TI - How and When Are Job Crafters Engaged at Work? AB - The importance of work engagement and the lack of engaged employees have led researchers to focus on how to enhance employees' levels of engagement in the workplace. Although job crafting as a principal driver of work engagement has recently received much attention from academics, little is known about the processes and conditions in which employees who craft their tasks become engaged. In order to address these research gaps, we hypothesize that psychological capital (PsyCap) is likely to mediate the association between job crafting and work engagement, and that coworker support, rather than supervisor support, is likely to moderate the relationship between job crafting and PsyCap. Further, we integrated these hypotheses and tested the moderated mediation effect. Using survey data from 175 flight attendants in South Korea, we found the results to be in line with our expectations. The findings of this empirical research contribute to the understanding of how and when job crafters become engaged at work. PMID- 30274210 TI - A Magnetoencephalographic/Encephalographic (MEG/EEG) Brain-Computer Interface Driver for Interactive iOS Mobile Videogame Applications Utilizing the Hadoop Ecosystem, MongoDB, and Cassandra NoSQL Databases. AB - In Phase I, we collected data on five subjects yielding over 90% positive performance in Magnetoencephalographic (MEG) mid-and post-movement activity. In addition, a driver was developed that substituted the actions of the Brain Computer Interface (BCI) as mouse button presses for real-time use in visual simulations. The process was interfaced to a flight visualization demonstration utilizing left or right brainwave thought movement, the user experiences, the aircraft turning in the chosen direction, or on iOS Mobile Warfighter Videogame application. The BCI's data analytics of a subject's MEG brain waves and flight visualization performance videogame analytics were stored and analyzed using the Hadoop Ecosystem as a quick retrieval data warehouse. In Phase II portion of the project involves the Emotiv Encephalographic (EEG) Wireless Brain-Computer interfaces (BCIs) allow for people to establish a novel communication channel between the human brain and a machine, in this case, an iOS Mobile Application(s). The EEG BCI utilizes advanced and novel machine learning algorithms, as well as the Spark Directed Acyclic Graph (DAG), Cassandra NoSQL database environment, and also the competitor NoSQL MongoDB database for housing BCI analytics of subject's response and users' intent illustrated for both MEG/EEG brainwave signal acquisition. The wireless EEG signals that were acquired from the OpenVibe and the Emotiv EPOC headset can be connected via Bluetooth to an iPhone utilizing a thin Client architecture. The use of NoSQL databases were chosen because of its schema-less architecture and Map Reduce computational paradigm algorithm for housing a user's brain signals from each referencing sensor. Thus, in the near future, if multiple users are playing on an online network connection and an MEG/EEG sensor fails, or if the connection is lost from the smartphone and the webserver due to low battery power or failed data transmission, it will not nullify the NoSQL document-oriented (MongoDB) or column oriented Cassandra databases. Additionally, NoSQL databases have fast querying and indexing methodologies, which are perfect for online game analytics and technology. In Phase II, we collected data on five MEG subjects, yielding over 90% positive performance on iOS Mobile Applications with Objective-C and C++, however on EEG signals utilized on three subjects with the Emotiv wireless headsets and (n < 10) subjects from the OpenVibe EEG database the Variational Bayesian Factor Analysis Algorithm (VBFA) yielded below 60% performance and we are currently pursuing extending the VBFA algorithm to work in the time-frequency domain referred to as VBFA-TF to enhance EEG performance in the near future. The novel usage of NoSQL databases, Cassandra and MongoDB, were the primary main enhancements of the BCI Phase II MEG/EEG brain signal data acquisition, queries, and rapid analytics, with MapReduce and Spark DAG demonstrating future implications for next generation biometric MEG/EEG NoSQL databases.

AB - Excessive pressure and shear stress while walking cause a risk of callus formation, which eventually causes foot ulcers in patients with diabetes mellitus. Callus under the second metatarsal head (MTH) has been associated with increased shear stress/pressure ratios (SPR). Callus under the fifth MTH has been associated with increased peak shear stress (PSS). The purpose of this study is to examine whether the effect of the suitable size and width of shoes prevents diabetic foot ulcers under the second and fifth MTH. We measured the pressure and shear stress by testing three kinds of sizes and two types of width of shoes. Significant difference was not observed in the SPR under the second MTH among different sizes of shoes. However, the pressure and shear stress were significantly lower when putting on shoes of fit size compared with larger sizes. The PSS under the fifth MTH was significantly smaller when putting on shoes of fit width compared with those of narrow width. Wearing shoes of fit size and width has the potential to prevent callus formation by reducing the pressure and shear stress constituting SPR under the second MTH and PSS under the fifth MTH. PMID- 30274211 TI - Integration of GPS, Monocular Vision, and High Definition (HD) Map for Accurate Vehicle Localization. AB - Self-localization is a crucial task for intelligent vehicles. Existing localization methods usually require high-cost IMU (Inertial Measurement Unit) or expensive LiDAR sensors (e.g., Velodyne HDL-64E). In this paper, we propose a low cost yet accurate localization solution by using a custom-level GPS receiver and a low-cost camera with the support of HD map. Unlike existing HD map-based methods, which usually requires unique landmarks within the sensed range, the proposed method utilizes common lane lines for vehicle localization by using Kalman filter to fuse the GPS, monocular vision, and HD map for more accurate vehicle localization. In the Kalman filter framework, the observations consist of two parts. One is the raw GPS coordinate. The other is the lateral distance between the vehicle and the lane, which is computed from the monocular camera. The HD map plays the role of providing reference position information and correlating the local lateral distance from the vision and the GPS coordinates so as to formulate a linear Kalman filter. In the prediction step, we propose using a data-driven motion model rather than a Kinematic model, which is more adaptive and flexible. The proposed method has been tested with both simulation data and real data collected in the field. The results demonstrate that the localization errors from the proposed method are less than half or even one-third of the original GPS positioning errors by using low cost sensors with HD map support. Experimental results also demonstrate that the integration of the proposed method into existing ones can greatly enhance the localization results. PMID- 30274207 TI - The Main Determinants of Diabetes Mellitus Vascular Complications: Endothelial Dysfunction and Platelet Hyperaggregation. AB - Diabetes mellitus is a common disease that affects 3-5% of the general population in Italy. In some countries of northern Europe or in North America, it can even affect 6-8% of the population. Of great concern is that the number of cases of diabetes is constantly increasing, probably due to the increase in obesity and the sedentary nature of the population. According to the World Health Organization, in the year 2030 there will be 360 million people with diabetes, compared to 170 million in 2000. This has important repercussions on the lives of patients and their families, and on health systems that offer assistance to patients. In this review, we try to describe in an organized way the pathophysiological continuity between diabetes mellitus, endothelial dysfunction, and platelet hyperaggregation, highlighting the main molecular mechanisms involved and the interconnections. PMID- 30274212 TI - Collective Efficacy: Development and Validation of a Measurement Scale for Use in Public Health and Development Programmes. AB - Impact evaluations of water, sanitation, and hygiene interventions have demonstrated lower than expected health gains, in some cases due to low uptake and sustained adoption of interventions at a community level. These findings represent common challenges for public health and development programmes relying on collective action. One possible explanation may be low collective efficacy (CE)-perceptions regarding a group's ability to execute actions related to a common goal. The purpose of this study was to develop and validate a metric to assess factors related to CE. We conducted this research within a cluster randomised sanitation and hygiene trial in Amhara, Ethiopia. Exploratory and confirmatory factor analyses were carried out to examine underlying structures of CE for men and women in rural Ethiopia. We produced three CE scales: one each for men and women that allow for examinations of gender-specific mechanisms through which CE operates, and one 26-item CE scale that can be used across genders. All scales demonstrated high construct validity. CE factor scores were significantly higher for men than women, even among household-level male-female dyads. These CE scales will allow implementers to better design and target community-level interventions, and examine the role of CE in the effectiveness of community-based programming. PMID- 30274213 TI - The Effects of Autophagy and PI3K/AKT/m-TOR Signaling Pathway on the Cell-Cycle Arrest of Rats Primary Sertoli Cells Induced by Zearalenone. AB - A high concentration of Zearalenone (ZEA) will perturb the differentiation of germ cells, and induce a death of germ cells, but the toxic mechanism and molecular mechanism remain unclear. The Sertoli cells (SCs) play an irreplaceable role in spermatogenesis. In order to explore the potential mechanism of ZEA male reproductive toxicity, we studied the effects of ZEA on cell proliferation, cell cycle distribution, cell-cycle-related proteins and autophagy-related pathway the PI3K/Akt/mTOR signaling in primary cultured rats SCs, and the effects of autophagy and PI3K/AKT/m TOR signaling pathway on the SCs cell-cycle arrest induced by ZEA treated with the autophagy promoter RAPA, autophagy inhibitor CQ, and the PI3K inhibitor LY294002, respectively. The data revealed that ZEA could inhibit the proliferation of SCs by arresting the cell cycle in the G2/M phase and trigger the autophagy via inhibiting the PI3K/Akt/m TOR signaling pathway. Promoting or inhibiting the level of autophagy could either augment or reverse the arrest of cell cycle. And it was regulated by PI3K/Akt/m TOR signaling pathway. Taken together, this study provides evidence that autophagy and PI3K/Akt/m TOR signaling pathway are involved in regulating rats primary SCs cell cycle arrest due to ZEA in vitro. To some extent, ZEA-induced autophagy plays a protective role in this process. PMID- 30274216 TI - Real-Time Monitoring of Tetraselmis suecica in A Saline Environment as Means of Early Water Pollution Detection. AB - Biological water pollution, including organic pollutants and their possible transportation, via biofouling and ballast water, has the potential to cause severe economic and health impacts on society and environment. Current water pollution monitoring methods are limited by transportation of samples to the laboratory for analysis, which could take weeks. There is an urgent need for a water quality monitoring technique that generates real-time data. The study aims to assess the feasibility of three sensing techniques to detect and monitor the concentrations of the model species Tetraselmis suecica in real-time using eleven samples for each method. Results showed UV-Vis spectrophotometer detected increasing concentration of Tetraselmis suecica with R2 = 0.9627 and R2 = 0.9672, at 450 nm and 650 nm wavelengths, respectively. Secondly, low-frequency capacitance measurements showed a linear relationship with increasing concentration of Tetraselmis suecica at 150 Hz (R2 = 0.8463) and 180 Hz (R2 = 0.8391). Finally, a planar electromagnetic wave sensor measuring the reflected power S11 amplitude detected increasing cell density at 4 GHz (R2 = 0.8019). PMID- 30274214 TI - Interactions between Triterpenes and a P-I Type Snake Venom Metalloproteinase: Molecular Simulations and Experiments. AB - Small molecule inhibitors of snake venom metalloproteinases (SVMPs) could provide a means to rapidly halt the progression of local tissue damage following viperid snake envenomations. In this study, we examine the ability of candidate compounds based on a pentacyclic triterpene skeleton to inhibit SVMPs. We leverage molecular dynamics simulations to estimate the free energies of the candidate compounds for binding to BaP1, a P-I type SVMP, and compare these results with experimental assays of proteolytic activity inhibition in a homologous enzyme (Batx-I). Both simulation and experiment suggest that betulinic acid is the most active candidate, with the simulations predicting a standard binding free energy of Delta G ? = - 11.0 +/- 1.4 kcal/mol. The simulations also reveal the atomic interactions that underlie binding between the triterpenic acids and BaP1, most notably the electrostatic interaction between carboxylate groups of the compounds and the zinc cofactor of BaP1. Together, our simulations and experiments suggest that occlusion of the S1 ' subsite is essential for inhibition of proteolytic activity. While all active compounds make hydrophobic contacts in the S1 ' site, beta -boswellic acid, with its distinct carboxylate position, does not occlude the S1 ' site in simulation and exhibits negligible activity in experiment. PMID- 30274215 TI - The Association between Nonalcoholic Fatty Liver Disease and CT-Measured Skeletal Muscle Mass. AB - A relationship between nonalcoholic fatty liver disease (NAFLD) and sarcopenia has been suggested. The aim of this study was to evaluate the association between NAFLD and skeletal muscle mass measured by computed tomography (CT). The clinical records of individuals visiting our center for a routine health check-up who underwent abdominal ultrasonography and abdominal CT scanning were retrospectively reviewed. Sarcopenia was diagnosed according to body mass index (BMI)-adjusted skeletal muscle mass, which was measured by CT (CT-measured skeletal muscle index (SMICT)). Of the 1828 subjects (1121 males; mean age 54.9 +/- 9.5 years), 487 (26.6%) were obese (BMI >= 25 kg/m2), and 454 (24.8%) had low muscle mass. Sarcopenic subjects had a significantly higher prevalence of NAFLD than nonsarcopenic subjects, regardless of obesity (35.9% vs. 26.8%, p = 0.004 in the nonobese group; 76.6% vs. 63.0%, p = 0.003 in the obese group). Sarcopenia was significantly associated with the risk of NAFLD (adjusted odds ratio (OR) (95% confidence interval (CI)), 1.51 (1.15-1.99)), and the risk of NAFLD increased with increasing severity of sarcopenia (adjusted OR (95% CI), 1.45 (1.09-1.92) vs. 2.51 (1.16-5.56), mild vs. severe sarcopenia, respectively). When the risk of NAFLD was analyzed according to the SMICT quartiles, the adjusted OR and 95% CI for the lowest muscle mass quartile compared to the highest were 1.78 (1.17-2.72) in males and 2.39 (1.13-5.37) in females. Low skeletal muscle mass, which was precisely measured by CT, is independently associated with NAFLD, suggesting that sarcopenia is a risk factor for NAFLD. PMID- 30274217 TI - Void Hole Avoidance for Reliable Data Delivery in IoT Enabled Underwater Wireless Sensor Networks. AB - Due to the limited availability of battery power of the acoustic node, an efficient utilization is desired. Additionally, the aquatic environment is harsh; therefore, the battery cannot be replaced, which leaves the network prone to sudden failures. Thus, an efficient node battery dissipation is required to prolong the network lifespan and optimize the available resources. In this paper, we propose four schemes: Adaptive transmission range in WDFAD-Depth-Based Routing (DBR) (A-DBR), Cluster-based WDFAD-DBR (C-DBR), Backward transmission-based WDFAD DBR (B-DBR) and Collision Avoidance-based WDFAD-DBR (CA-DBR) for Internet of Things-enabled Underwater Wireless Sensor Networks (IoT, UWSNs). A-DBR adaptively adjusts its transmission range to avoid the void node for forwarding data packets at the sink, while C-DBR minimizes end-to-end delay along with energy consumption by making small clusters of nodes gather data. In continuous transmission range adjustment, energy consumption increases exponentially; thus, in B-DBR, a fall back recovery mechanism is used to find an alternative route to deliver the data packet at the destination node with minimal energy dissipation; whereas, CA-DBR uses a fall back mechanism along with the selection of the potential node that has the minimum number of neighbors to minimize collision on the acoustic channel. Simulation results show that our schemes outperform the baseline solution in terms of average packet delivery ratio, energy tax, end-to-end delay and accumulated propagation distance. PMID- 30274218 TI - Highly-Ordered PdIn Intermetallic Nanostructures Obtained from Heterobimetallic Acetate Complex: Formation and Catalytic Properties in Diphenylacetylene Hydrogenation. AB - Formation of PdIn intermetallic nanoparticles supported on alpha-Al2O3 was investigated by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and hydrogen temperature-programmed desorption (H2-TPD) methods. The metals were loaded as heterobimetallic Pd(MU-O2CMe)4In(O2CMe) complex to ensure intimate contact between Pd and In. Reduction in H2 at 200 degrees C resulted in Pd-rich PdIn alloy as evidenced by XRD and the disappearance of Pd hydride. A minor amount of Pd1In1 intermetallic phase appeared after reduction at 200 degrees C and its formation was accomplished at 400 degrees C. Neither monometallic Pd or in nor other intermetallic structures were found after reduction at 400-600 degrees C. Catalytic performance of Pd1In1/alpha-Al2O3 was studied in the selective liquid-phase diphenylacetylene (DPA) hydrogenation. It was found that the reaction rate of undesired alkene hydrogenation is strongly reduced on Pd1In1 nanoparticles enabling effective kinetic control of the hydrogenation, and the catalyst demonstrated excellent selectivity to alkene. PMID- 30274219 TI - Dinophysis acuta in Scottish Coastal Waters and Its Influence on Diarrhetic Shellfish Toxin Profiles. AB - Diarrhetic shellfish toxins produced by the dinoflagellate genus Dinophysis are a major problem for the shellfish industry worldwide. Separate species of the genus have been associated with the production of different analogues of the okadaic acid group of toxins. To evaluate the spatial and temporal variability of Dinophysis species and toxins in the important shellfish-harvesting region of the Scottish west coast, we analysed data collected from 1996 to 2017 in two contrasting locations: Loch Ewe and the Clyde Sea. Seasonal studies were also undertaken, in Loch Ewe in both 2001 and 2002, and in the Clyde in 2015. Dinophysis acuminata was present throughout the growing season during every year of the study, with blooms typically occurring between May and September at both locations. The appearance of D. acuta was interannually sporadic and, when present, was most abundant in the late summer and autumn. The Clyde field study in 2015 indicated the importance of a temperature front in the formation of a D. acuta bloom. A shift in toxin profiles of common mussels (Mytilus edulis) tested during regulatory monitoring was evident, with a proportional decrease in okadaic acid (OA) and dinophysistoxin-1 (DTX1) and an increase in dinophysistoxin-2 (DTX2) occurring when D. acuta became dominant. Routine enumeration of Dinophysis to species level could provide early warning of potential contamination of shellfish with DTX2 and thus determine the choice of the most suitable kit for effective end-product testing. PMID- 30274220 TI - Expression Analysis of the Prolific Candidate Genes, BMPR1B, BMP15, and GDF9 in Small Tail Han Ewes with Three Fecundity (FecB Gene) Genotypes. AB - The expression characteristics of the prolific candidate genes, BMPR1B, BMP15, and GDF9, in the major visceral organs and hypothalamic-pituitary-gonadal (HPG) axis tissues of three FecB genotypes (FecB BB, FecB B+, and FecB ++) were explored in STH ewes using RT-PCR and qPCR. The results were as follows, BMPR1B was expressed in all FecB BB genotype (Han BB) tissues, and GDF9 was expressed in all selected tissues, but BMP15 was specifically expressed in the ovaries. Further study of ovarian expression indicated that there was no difference in BMPR1B expression between genotypes, but the FecB B+ genotype (Han B+) had greater expression of GDF9 and BMP15 than Han BB and FecB ++ genotype (Han ++) (p < 0.05, p < 0.01). BMP15 expression was lower in the ovaries of Han BB than in Han ++ sheep, but the reverse was shown for GDF9. The gene expression in non ovarian tissues was also different between genotypes. Therefore, we consider that the three genes have an important function in ovine follicular development and maturation. This is the first systematic analysis of the tissue expression pattern of BMPR1B, BMP15, and GDF9 genes in STH sheep of the three FecB genotypes. These results contribute to the understanding of the molecular regulatory mechanism for ovine reproduction. PMID- 30274221 TI - Accelerometric Trunk Sensors to Detect Changes of Body Positions in Immobile Patients. AB - Mobilization, verticalization and position change are mandatory for severely affected neurological patients in early neurorehabilitation in order to improve neurological status and prevent complications. However, with the exception of hospitals and rehabilitation facilities, this activity is not usually monitored and so far the automated monitoring of position changes in immobile patients has not been investigated. Therefore, we investigated whether accelerometers on the upper trunk could reliably detect body position changes in immobile patients. Thirty immobile patients in early neurorehabilitation (Barthel Index <= 30) were enrolled. Two tri-axial accelerometers were placed on the upper trunk and on the thigh. Information on the position and position changes of the subject were derived from accelerometer data and compared to standard written documentation in the hospital over 24 h. Frequency and duration of different body positions (supine, sidelying, sitting) were measured. Data are presented as mean +/- SEM. Groups were compared using one-way ANOVA or Kruskal-Wallis-test. Differences were considered significant if p < 0.05. Trunk sensors detected 100% and thigh sensors 66% of position changes (p = 0.0004) compared to standard care documentation. Furthermore, trunk recording also detected additional spontaneous body position changes that were not documented in standard care (81.8 +/- 4.4% of all position changes were documented in standard care documentation) (p < 0.0001). We found that accelerometric trunk sensors are suitable for recording position changes and mobilization of severely affected patients. Our findings suggest that using accelerometers for care documentation is useful for monitoring position changes and mobilization frequencies in and outside of hospital for severely affected neurological patients. Accelerometric sensors may be valuable in monitoring continuation of care plans after intensive neurorehabilitation. PMID- 30274222 TI - Configuration Optimization Design of Ti6Al4V Lattice Structure Formed by SLM. AB - Previous studies have revealed the influence of various lattice structures on the material density and mechanical properties. However, the majority of the topologies that are considered as study objects directly refer to metal/non crystal lattice cell configurations. Therefore, this paper proposes a configuration generation approach for generating a lattice structure, which can obtain a lattice configuration that enjoys the advantages of both ultra-low weight and favorable mechanical properties. Based on this approach, a new type of face-centered cubic lattice (all face-centered cubic, AFCC) structure with comprehensively optimal properties in terms of mass and mechanical properties is obtained. The experimental samples are formed with Ti6Al4V by the selective laser melting (SLM) method. Quasi-static uniaxial compression performance experiments and finite element analysis (FEA) are conducted on an AFCC structure and the control group body-centered cubic (BCC) structure. The results demonstrates that our optimized AFCC lattice structure is superior to the BCC structure, with elastic modulus and yield limit increases of 143% and 120%, respectively. For the same degree of deformation, the energy absorbed increases approximately 2.4 times. The AFCC demonstrates significant advantages in terms of its mechanical properties and anti-explosion impact resistance while maintaining favorable ultra low weight, which validates the hypothesis that the proposed configuration generation approach can provide guidance for the design and further research on ultra-light lattice structures in related fields.

AB - High 17beta-Estradiol (E2) levels are known to cause alterations of spermatogenesis and environments throughout the male reproductive tract. Sertoli cells (SCs) ensure an adequate environment inside the seminiferous tubule. Glycerol stands as essential for the maintenance of blood-testis barrier created by SCs, however, the role of E2 in this process is not known. Herein, we hypothesized that the effect of E2 on glycerol permeability in mouse SCs (mSCs) could be mediated by aquaglyceroporins. The expression of aquaglyceroporins was assessed by RT-PCR and qRT-PCR. Glycerol permeability was evaluated by stopped flow light scattering. We were able to identify the expression of AQP3 and AQP9 in mSCs where AQP9 is more abundant than AQP3. Our results show that high E2 levels decrease AQP9 mRNA abundance with no influence on AQP3 in mSCs. Interestingly, high E2 levels decreased mSCs' permeability to glycerol, while downregulating AQP9 expression, thus suggesting a novel mechanism by which E2 modulates fluid secretion in the testis. In conclusion, E2 is an important regulator of mSCs physiology and secretion through changes in AQP9 expression and function. Thus, alterations in glycerol permeability induced by E2 may be the cause for male infertility in cases associated with the presence of high E2 levels.

AB - When certain polymers are heat-treated beyond their degradation temperature in the absence of oxygen, they pass through a semi-solid phase, followed by the loss of heteroatoms and the formation of a solid carbon material composed of a three dimensional graphenic network, known as glassy (or glass-like) carbon. The thermochemical decomposition of polymers, or generally of any organic material, is defined as pyrolysis. Glassy carbon is used in various large-scale industrial applications and has proven its versatility in miniaturized devices. In this article, micro and nano-scale glassy carbon devices manufactured by (i) pyrolysis of specialized pre-patterned polymers and (ii) direct machining or etching of glassy carbon, with their respective applications, are reviewed. The prospects of the use of glassy carbon in the next-generation devices based on the material's history and development, distinct features compared to other elemental carbon forms, and some large-scale processes that paved the way to the state-of-the-art, are evaluated. Selected support techniques such as the methods used for surface modification, and major characterization tools are briefly discussed. Barring historical aspects, this review mainly covers the advances in glassy carbon device research from the last five years (2013-2018). The goal is to provide a common platform to carbon material scientists, micro/nanomanufacturing experts, and microsystem engineers to stimulate glassy carbon device research.

AB - In order to provide a more detailed view on the structure-antimycobacterial activity relationship (SAR) of phenylcarbamic acid derivatives containing two centers of protonation, 1-[2-[({[2-/3-(alkoxy)phenyl]amino}carbonyl)oxy]-3 (dipropylammonio)propyl]pyrrolidinium oxalates (1a-d)/dichlorides (1e-h) as well as 1-[2-[({[2-/3-(alkoxy)phenyl]amino}carbonyl)oxy]-3-(di propylammonio)propyl]azepanium oxalates (1i-l)/dichlorides (1m-p; alkoxy = butoxy to heptyloxy) were physicochemically characterized by estimation of their surface tension (gamma; Traube's stalagmometric method), electronic features (log epsilon; UV/Vis spectrophotometry) and lipophilic properties (log kw; isocratic RP-HPLC) as well. The experimental log kw dataset was studied together with computational logarithms of partition coefficients (log P) generated by various methods based mainly on atomic or combined atomic and fragmental principles. Similarities and differences between the experimental and in silico lipophilicity descriptors were analyzed by unscaled principal component analysis (PCA). The in vitro activity of compounds 1a-p was inspected against Mycobacterium tuberculosis CNCTC My 331/88 (identical with H37Rv and ATCC 2794, respectively), M. tuberculosis H37Ra ATCC 25177, M. kansasii CNCTC My 235/80 (identical with ATCC 12478), the M. kansasii 6509/96 clinical isolate, M. kansasii DSM 44162, M. avium CNCTC My 330/80 (identical with ATCC 25291), M. smegmatis ATCC 700084 and M. marinum CAMP 5644, respectively. In vitro susceptibility of the mycobacteria to reference drugs isoniazid, ethambutol, ofloxacin or ciprofloxacin was tested as well. A very unique aspect of the research was that many compounds from the set 1a-p were highly efficient almost against all tested mycobacteria. The most promising derivatives showed MIC values varied from 1.9 MUM to 8 MUM, which were lower compared to those of used standards, especially if concerning ability to fight M. tuberculosis H37Ra ATCC 25177, M. kansasii DSM 44162 or M. avium CNCTC My 330/80. Current in vitro biological assays and systematic SAR studies based on PCA approach as well as fitting procedures, which were supported by relevant statistical descriptors, proved that the compounds 1a-p represented a very promising molecular framework for development of 'non-traditional' but effective antimycobacterial agents.

AB - Design approaches towards energy efficient hospitals often result in a deteriorated indoor environmental quality, adverse health and comfort outcomes, and is a public health concern. This research presents an advanced approach to the design of a hospital environment based on a stimulative paradigm of healing to achieve not only healthy but also comforting conditions. A hospital room for severely burn patient was considered as one of the most demanding spaces. The healing environment was designed as a multi-levelled, dynamic process including the characteristics of users, building and systems. The developed integral user centred cyber-physical system (UCCPS) was tested in a test room and compared to the conventional system. The thermodynamic responses of burn patients, health care worker and visitor were simulated by using modified human body exergy models. In a healing environment, UCCPS enables optimal thermal balance, individually regulated according to the user specifics. For burn patient it creates optimal healing-oriented conditions with the lowest possible human body exergy consumption (hbExC), lower metabolic thermal exergy, lower sweat exhalation, evaporation, lower radiation and convection. For healthcare workers and visitors, thermally comfortable conditions are attained with minimal hbExC and neutral thermal load on their bodies. The information on this is an aid in integral hospital design, especially for future extensive renovations and environmental health actions. PMID- 30274227 TI - Quantitative Determination of Cd in Soil Using Laser-Induced Breakdown Spectroscopy in Air and Ar Conditions. AB - Rapid detection of Cd content in soil is beneficial to the prevention of soil heavy metal pollution. In this study, we aimed at exploring the rapid quantitative detection ability of laser- induced breakdown spectroscopy (LIBS) under the conditions of air and Ar for Cd in soil, and finding a fast and accurate method for quantitative detection of heavy metal elements in soil. Spectral intensity of Cd and system performance under air and Ar conditions were analyzed and compared. The univariate model and multivariate models of partial least-squares regression (PLSR) and least-squares support vector machine (LS-SVM) of Cd under the air and Ar conditions were built, and the LS-SVM model under the Ar condition obtained the best performance. In addition, the principle of influence of Ar on LIBS detection was investigated by analyzing the three dimensional profile of the ablation crater. The overall results indicated that LIBS combined with LS-SVM under the Ar condition could be a useful tool for the accurate quantitative detection of Cd in soil and could provide reference for environmental monitoring. PMID- 30274228 TI - A New Method for Predicting Erosion Damage of Suddenly Contracted Pipe Impacted by Particle Cluster via CFD-DEM. AB - A numerical study on the erosion of particle clusters in an abrupt pipe was conducted by means of the combined computational fluid dynamics (CFD) and discrete element methods (DEM). Furthermore, a particle-wall extrusion model and a criterion for judging particle collision interference were developed to classify and calculate the erosion rate caused by different interparticle collision mechanisms in a cluster. Meanwhile, a full-scale pipe flow experiment was conducted to confirm the effect of a particle cluster on the erosion rate and to verify the calculated results. The reducing wall was made of super 13Cr stainless steel materials and the round ceramsite as an impact particle was 0.65 mm in diameter and 1850 kg/m3 in density. The results included an erosion depth, particle-wall contact parameters, and a velocity decay rate of colliding particles along the radial direction at the target surface. Subsequently, the effect of interparticle collision mechanisms on particle cluster erosion was discussed. The calculated results demonstrate that collision interference between particles during one cluster impact was more likely to appear on the surface with large particle impact angles. This collision process between the rebounded particles and the following particles not only consumed the kinetic energy but also changed the impact angle of the following particles.

AB - In recent years, Thorpe analysis has been used to retrieve the characteristics of turbulence in free atmosphere from balloon-borne sensor data. However, previous studies have mainly focused on the mid-high latitude region, and this method is still rarely applied at heights above 30 km, especially above 35 km. Therefore, seven sets of upper air (>35 km) sounding data from the Changsha Sounding Station (28 degrees 12' N, 113 degrees 05' E), China are analyzed with Thorpe analysis in this article. It is noted that, in the troposphere, Thorpe analysis can better retrieve the turbulence distribution and the corresponding turbulence parameters. Also, because of the thicker troposphere at low latitudes, the values of the Thorpe scale L T and turbulent energy dissipation rate epsilon remain greater in a larger height range. In the stratosphere below the height of 35 km, the obtained epsilon is higher, and Thorpe analysis can only be used to analyze the characteristics of large-scale turbulence. In the stratosphere at a height of 35 40 km, because of the interference of sensor noise, Thorpe analysis can only help to retrieve the rough distribution position of large-scale turbulence, while it can hardly help with the calculation of the turbulence parameters.

PMID- 30274232 TI - Biocompatible Coatings from Smart Biopolymer Nanoparticles for Enzymatically Induced Drug Release. AB - Nanoparticles can be used as a smart drug delivery system, when they release the drug only upon degradation by specific enzymes. A method to create such responsive materials is the formation of hydrogel nanoparticles, which have enzymatically degradable crosslinkers. Such hydrogel nanoparticles were prepared by ionotropic gelation sodium alginate with lysine-rich peptide sequences-either alpha-poly-L-lysine (PLL) or the aggrecanase-labile sequence KKKK-GRD ARGSV?NITEGE-DRG-KKKK. The nanoparticle suspensions obtained were analyzed by means of dynamic light scattering and nanoparticle tracking analysis. Degradation experiments carried out with the nanoparticles in suspension revealed enzyme induced lability. Drugs present in the polymer solution during the ionotropic gelation can be encapsulated in the nanoparticles. Drug loading was investigated for interferon-beta (IFN-beta) as a model, using a bioluminescence assay with MX2Luc2 cells. The encapsulation efficiency for IFN-beta was found to be approximately 25%. The nanoparticles suspension can be used to spray-coat titanium alloys (Ti-6Al-4V) as a common implant material. The coatings were proven by ellipsometry, reflection-absorption infrared spectroscopy, and X-ray photoelectron spectroscopy. An enzyme-responsive decrease in layer thickness is observed due to the degradation of the coatings. The Alg/peptide coatings were cytocompatible for human gingival fibroblasts (HGFIB), which was investigated by CellTiterBlue and lactate dehydrogenase (LDH) assay. However, HGFIBs showed poor adhesion and proliferation on the Alg/peptide coatings, but these could be improved by modification of the alginate with a RGD-peptide sequence. The smart drug release system presented can be further tailored to have the right release kinetics and cell adhesion properties. PMID- 30274229 TI - Redox Signaling of NADPH Oxidases Regulates Oxidative Stress Responses, Immunity and Aging. AB - An accumulating body of evidence suggests that transient or physiological reactive oxygen species (ROS) generated by nicotinamide adenine dinucleotide phosphate (NADPH) oxidases act as a redox signal to re-establish homeostasis. The capacity to re-establish homeostasis progressively declines during aging but is maintained in long-lived animals to promote healthy aging. In the model organism Caenorhabditis elegans, ROS generated by dual oxidases (Duox) are important for extracellular matrix integrity, pathogen defense, oxidative stress resistance, and longevity. The Duox enzymatic activity is tightly regulated and under cellular control. Developmental molting cycles, pathogen infections, toxins, mitochondrial-derived ROS, drugs, and small GTPases (e.g., RHO-1) can activate Duox (BLI-3) to generate ROS, whereas NADPH oxidase inhibitors and negative regulators, such as MEMO-1, can inhibit Duox from generating ROS. Three mechanisms-of-action have been discovered for the Duox/BLI-3-generated ROS: (1) enzymatic activity to catalyze crosslinking of free tyrosine ethyl ester in collagen bundles to stabilize extracellular matrices, (2) high ROS bursts/levels to kill pathogens, and (3) redox signaling activating downstream kinase cascades to transcription factors orchestrating oxidative stress and immunity responses to re-establish homeostasis. Although Duox function at the cell surface is well established, recent genetic and biochemical data also suggests a novel role for Duoxs at the endoplasmic reticulum membrane to control redox signaling. Evidence underlying these mechanisms initiated by ROS from NADPH oxidases, and their relevance for human aging, are discussed in this review. Appropriately controlling NADPH oxidase activity for local and physiological redox signaling to maintain cellular homeostasis might be a therapeutic strategy to promote healthy aging. PMID- 30274233 TI - A Cross-Sectional Study of Experiences and Attitudes towards Clinical Audit of Farm Animal Veterinary Surgeons in the United Kingdom. AB - Clinical audit is a quality improvement tool used to assess and improve the clinical services provided to patients. This is the first study to investigate the extent to which clinical audit is understood and utilised in farm animal veterinary practice. A cross-sectional study to collect experiences and attitudes of farm animal veterinary surgeons in the UK towards clinical audit was conducted using an online nationwide survey. The survey revealed that whilst just under three-quarters (n = 237/325; 73%) of responding veterinary surgeons had heard of clinical audit, nearly 50% (n = 148/301) had never been involved in a clinical audit of any species. The participants' knowledge of what a clinical audit was varied substantially, with many respondents reporting not receiving training on clinical audit at the undergraduate or postgraduate level. Respondents that had participated in a clinical audit suggested that protected time away from clinical work was required for the process to be completed successfully. This novel study suggests that clinical audit is undertaken to some extent in farm animal practice and that practitioner perception is that it can bring benefits, but was felt that more resources and support were needed for it to be implemented successfully on a wider scale. PMID- 30274235 TI - Chemoresistance in H-Ferritin Silenced Cells: The Role of NF-kappaB. AB - Nuclear Factor-kappaB (NF-kappaB) is frequently activated in tumor cells contributing to aggressive tumor growth and resistance to chemotherapy. Here we demonstrate that Ferritin Heavy Chain (FHC) protein expression inversely correlates with NF-kappaB activation in cancer cell lines. In fact, FHC silencing in K562 and SKOV3 cancer cell lines induced p65 nuclear accumulation, whereas FHC overexpression correlated with p65 nuclear depletion in the same cell lines. In FHC-silenced cells, the p65 nuclear accumulation was reverted by treatment with the reactive oxygen species (ROS) scavenger, indicating that NF-kappaB activation was an indirect effect of FHC on redox metabolism. Finally, FHC knock-down in K562 and SKOV3 cancer cell lines resulted in an improved cell viability following doxorubicin or cisplatin treatment, being counteracted by the transient expression of inhibitory of NF-kappaB, IkappaBalpha. Our results provide an additional layer of information on the complex interplay of FHC with cellular metabolism, and highlight a novel scenario of NF-kappaB-mediated chemoresistance triggered by the downregulation of FHC with potential therapeutic implications. PMID- 30274234 TI - Whole-Genome Sequencing of 84 Japanese Eels Reveals Evidence against Panmixia and Support for Sympatric Speciation. AB - The Japanese eel (Anguilla japonica), European eel (Anguilla anguilla), and American eel (Anguilla rostrata) are migratory, catadromous, temperate zone fish sharing several common life cycle features. The population genetics of panmixia in these eel species has already been investigated. Our extensive population genetics analysis was based on 1400 Gb of whole-genome sequence (WGS) data from 84 eels. It demonstrated that a Japanese eel group from the Kuma River differed from other populations of the same species. Even after removing the potential adapted/selected single nucleotide polymorphism (SNP) data, and with very small differences (fixation index [Fst] = 0.01), we obtained results consistently indicating that panmixia does not occur in Japanese eels. The life cycle of the Japanese eel is well-established and the Kuma River is in the center of its habitat. Nevertheless, simple reproductive isolation is not the probable cause of non-panmixia in this species. We propose that the combination of spawning area subdivision, philopatry, and habitat preference/avoidance accounts for the non panmixia in the Japanese eel population. We named this hypothesis the "reproductive isolation like subset mapping" (RISM) model. This finding may be indicative of the initial stages of sympatric speciation in these eels. PMID- 30274237 TI - A Label-Free Fluorescent DNA Calculator Based on Gold Nanoparticles for Sensitive Detection of ATP. AB - Herein we described a deoxyribonucleic acid (DNA) calculator for sensitive detection of the determination of adenosine triphosphate (ATP) using gold nanoparticles (GNP) and PicoGreen fluorescence dye as signal transducer, and ATP and single-stranded DNA (DNA-M') as activators. The calculator-related performances including linearity, reaction time, logic gate, and selectivity were investigated, respectively. The results revealed that this oligonucleotide sensor was highly sensitive and selective. The detection range was 50-500 nmol/L (R2 = 0.99391) and the detection limit was 46.5 nmol/L. The AND DNA calculator was successfully used for the ATP detection in human urine. Compared with other methods, this DNA calculator has the characteristics of being label-free, non enzymic, simple, and highly sensitive. PMID- 30274238 TI - Validity of Capsule Endoscopy in Monitoring Therapeutic Interventions in Patients with Crohn's Disease. AB - Mucosal healing in Crohn's disease (CD) can be evaluated by capsule endoscopy (CE). However, only a few studies have utilized CE to demonstrate the therapeutic effect of medical treatment. We sought to evaluate the validity of using CE to monitor the effect of medical treatment in patients with CD. One hundred (n = 100) patients with CD were enrolled. All patients had a gastrointestinal (GI) tract patency check prior to CE. Patients with baseline CE Lewis score (LS) <= 135 were included in the non-active CD group and ended the study. In those with LS > 135 (active CD group), additional treatment was administered, regardless of symptoms, as per the treating clinician's advice. Patients of the active CD group underwent follow-up CE assessment 6 months later. Out of 92 patients with confirmed GI patency who underwent CE, 40 (43.4%) had CE findings of active inflammation. Of 29 patients with LS > 135 who received additional medications and underwent follow-up CE, improvement of the LS was noted in 23 (79.3%) patients. Eleven patients were asymptomatic but received additional medications; 8 (72.7%) had improvement of the LS. This study demonstrated that additional treatment even for patients with CD in clinical remission and active small-bowel inflammation on CE can reduce mucosal damage. PMID- 30274239 TI - Sintering Behavior and Mechanical Properties of Mullite Fibers/Hydroxyapatite Ceramic. AB - The effect of fiber content and sintering temperature on sintering behavior and mechanical properties of mullite fibers/hydroxyapatite composites was studied. The composites were fabricated by hydrothermal synthesis and pressureless sintering. The amount of fibers was varied from 5 wt % to 15 wt % through hydrothermal synthesis, mullite fibers and hydroxyapatite composite powders were subsequently sintered at temperatures of 1150, 1250, and 1350 degrees C. The composites presented a more perturbed structure by increasing fiber content. Moreover, the composites experienced pore coalescence and exhibited a dense microstructure at elevated temperature. X-ray diffraction indicated that the composites underwent various chemical reactions and generated silicate glasses. The generation of silicate glasses increased the driving force of particle rearrangement and decreased the number of pores, which promoted densification of the composites. Densification typically leads to increased hardness and bending strength. The study proposes a densification mechanism and opens new insights into the sintering properties of these materials. PMID- 30274236 TI - The Interplay among PINK1/PARKIN/Dj-1 Network during Mitochondrial Quality Control in Cancer Biology: Protein Interaction Analysis. AB - PARKIN (E3 ubiquitin ligase PARK2), PINK1 (PTEN induced kinase 1) and DJ-1 (PARK7) are proteins involved in autosomal recessive parkinsonism, and carcinogenic processes. In damaged mitochondria, PINK1's importing into the inner mitochondrial membrane is prevented, PARKIN presents a partial mitochondrial localization at the outer mitochondrial membrane and DJ-1 relocates to mitochondria when oxidative stress increases. Depletion of these proteins result in abnormal mitochondrial morphology. PINK1, PARKIN, and DJ-1 participate in mitochondrial remodeling and actively regulate mitochondrial quality control. In this review, we highlight that PARKIN, PINK1, and DJ-1 should be regarded as having an important role in Cancer Biology. The STRING database and Gene Ontology (GO) enrichment analysis were performed to consolidate knowledge of well-known protein interactions for PINK1, PARKIN, and DJ-1 and envisage new ones. The enrichment analysis of KEGG pathways showed that the PINK1/PARKIN/DJ-1 network resulted in Parkinson disease as the main feature, while the protein DJ-1 showed enrichment in prostate cancer and p53 signaling pathway. Some predicted transcription factors regulating PINK1, PARK2 (PARKIN) and PARK7 (DJ-1) gene expression are related to cell cycle control. We can therefore suggest that the interplay among PINK1/PARKIN/DJ-1 network during mitochondrial quality control in cancer biology may occur at the transcriptional level. Further analysis, like a systems biology approach, will be helpful in the understanding of PINK1/PARKIN/DJ 1 network. PMID- 30274240 TI - Evidence of Mercury Methylation and Demethylation by the Estuarine Microbial Communities Obtained in Stable Hg Isotope Studies. AB - Microbial activity is a critical factor controlling methylmercury formation in aquatic environments. Microbial communities were isolated from sediments of two highly mercury-polluted areas of the Tagus Estuary (Barreiro and Cala do Norte) and differentiated according to their dependence on oxygen into three groups: aerobic, anaerobic, and sulphate-reducing microbial communities. Their potential to methylate mercury and demethylate methylmercury was evaluated through incubation with isotope-enriched Hg species (199HgCl and CH3201HgCl). The results showed that the isolated microbial communities are actively involved in methylation and demethylation processes. The production of CH3199Hg was positively correlated with sulphate-reducing microbial communities, methylating up to 0.07% of the added 199Hg within 48 h of incubation. A high rate of CH3201Hg degradation was observed and >20% of CH3201Hg was transformed. Mercury removal of inorganic forms was also observed. The results prove the simultaneous occurrence of microbial methylation and demethylation processes and indicate that microorganisms are mainly responsible for methylmercury formation and accumulation in the polluted Tagus Estuary. PMID- 30274241 TI - Effects of Jaw Periosteal Cells on Dendritic Cell Maturation. AB - Clinical application of tissue engineering products requires the exclusion of immune responses after implantation. We used jaw periosteal cells (JPCs) as a suitable stem cell source and analyzed herein the effects of JPCs on dendritic cell maturation after co-culturing of both cell types. Peripheral blood mononuclear cells (PBMCs) were differentiated to dendritic cells (DCs) by the addition of differentiation cocktails for 7 days in co-culture with undifferentiated and osteogenically induced JPCs. The effects of JPCs on DC maturation were analyzed at the beginning (day 7), in the middle (day 14), and at the end (day 21) of the osteogenesis process. We detected significantly lower DC numbers after co-culturing with JPCs that have previously been left untreated or osteogenically differentiated for 7, 14, and 21 days. Using gene expression analyses, significantly lower IL-12p35 and -p40 and pro-inflammatory cytokine (IFN-gamma and TNF-alpha) levels were detected, whereas IL-8 mRNA levels were significantly higher in DCs. Furthermore, osteogenic media conditions enhanced significantly IL-10 gene expression. We concluded that undifferentiated and osteogenically differentiated JPCs had an overall inhibiting influence on dendritic cell maturation. Further studies should clarify the underlaying mechanism in depth. PMID- 30274242 TI - Role of KCa3.1 Channels in Modulating Ca2+ Oscillations during Glioblastoma Cell Migration and Invasion. AB - Cell migration and invasion in glioblastoma (GBM), the most lethal form of primary brain tumors, are critically dependent on Ca2+ signaling. Increases of [Ca2+]i in GBM cells often result from Ca2+ release from the endoplasmic reticulum (ER), promoted by a variety of agents present in the tumor microenvironment and able to activate the phospholipase C/inositol 1,4,5 trisphosphate PLC/IP3 pathway. The Ca2+ signaling is further strengthened by the Ca2+ influx from the extracellular space through Ca2+ release-activated Ca2+ (CRAC) currents sustained by Orai/STIM channels, meant to replenish the partially depleted ER. Notably, the elevated cytosolic [Ca2+]i activates the intermediate conductance Ca2+-activated K (KCa3.1) channels highly expressed in the plasma membrane of GBM cells, and the resulting K+ efflux hyperpolarizes the cell membrane. This translates to an enhancement of Ca2+ entry through Orai/STIM channels as a result of the increased electromotive (driving) force on Ca2+ influx, ending with the establishment of a recurrent cycle reinforcing the Ca2+ signal. Ca2+ signaling in migrating GBM cells often emerges in the form of intracellular Ca2+ oscillations, instrumental to promote key processes in the migratory cycle. This has suggested that KCa3.1 channels may promote GBM cell migration by inducing or modulating the shape of Ca2+ oscillations. In accordance, we recently built a theoretical model of Ca2+ oscillations incorporating the KCa3.1 channel-dependent dynamics of the membrane potential, and found that the KCa3.1 channel activity could significantly affect the IP3 driven Ca2+ oscillations. Here we review our new theoretical model of Ca2+ oscillations in GBM, upgraded in the light of better knowledge of the KCa3.1 channel kinetics and Ca2+ sensitivity, the dynamics of the Orai/STIM channel modulation, the migration and invasion mechanisms of GBM cells, and their regulation by Ca2+ signals. PMID- 30274243 TI - Ab Initio Molecular Dynamics Simulation Study on the Stereo Reactions between Atomic Oxygen Anion and Methane. AB - Ion-molecule reaction between atomic oxygen anion (O-) and methane (CH4) has been systematically investigated employing the on-the-fly ab initio molecular dynamics simulations. Besides the major H-abstraction process as the exothermic reaction studied widely, an endothermic pathway to produce OCH3- and H is also observed in this study. Three typical O- attack modes with reference to the pyramid structure of CH4 fixed in space have been considered. It was found that the internal motions of the radical products are significantly dependent on the O- attack modes. As for the reaction between O- and the thermally vibrating CH4, the major pathway to produce OH- and CH3 is preferred by the direct H-abstraction and the minor pathway to produce H and OCH3- is the roaming reaction via the transient negative ion [HO-CH3]-.

PMID- 30274246 TI - Considerations of AOX Functionality Revealed by Critical Motifs and Unique Domains. AB - An understanding of the genes and mechanisms regulating environmental stress in crops is critical for boosting agricultural yield and safeguarding food security. Under adverse conditions, response pathways are activated for tolerance or resistance. In multiple species, the alternative oxidase (AOX) genes encode proteins which help in this process. Recently, this gene family has been extensively investigated in the vital crop plants, wheat, barley and rice. Cumulatively, these three species and/or their wild ancestors contain the genes for AOX1a, AOX1c, AOX1e, and AOX1d, and common patterns in the protein isoforms have been documented. Here, we add more information on these trends by emphasizing motifs that could affect expression, and by utilizing the most recent discoveries from the AOX isoform in Trypanosoma brucei to highlight clade dependent biases. The new perspectives may have implications on how the AOX gene family has evolved and functions in monocots. The common or divergent amino acid substitutions between these grasses and the parasite are noted, and the potential effects of these changes are discussed. There is the hope that the insights gained will inform the way future AOX research is performed in monocots, in order to optimize crop production for food, feed, and fuel. PMID- 30274245 TI - Regulation and Metabolic Significance of De Novo Lipogenesis in Adipose Tissues. AB - De novo lipogenesis (DNL) is a complex and highly regulated process in which carbohydrates from circulation are converted into fatty acids that are then used for synthesizing either triglycerides or other lipid molecules. Dysregulation of DNL contributes to human diseases such as obesity, type 2 diabetes, and cardiovascular diseases. Thus, the lipogenic pathway may provide a new therapeutic opportunity for combating various pathological conditions that are associated with dysregulated lipid metabolism. Hepatic DNL has been well documented, but lipogenesis in adipocytes and its contribution to energy homeostasis and insulin sensitivity are less studied. Recent reports have gained significant insights into the signaling pathways that regulate lipogenic transcription factors and the role of DNL in adipose tissues. In this review, we will update the current knowledge of DNL in white and brown adipose tissues with the focus on transcriptional, post-translational, and central regulation of DNL. We will also summarize the recent findings of adipocyte DNL as a source of some signaling molecules that critically regulate energy metabolism. PMID- 30274248 TI - Oncobox Bioinformatical Platform for Selecting Potentially Effective Combinations of Target Cancer Drugs Using High-Throughput Gene Expression Data. AB - Sequential courses of anticancer target therapy lead to selection of drug resistant cells, which results in continuous decrease of clinical response. Here we present a new approach for predicting effective combinations of target drugs, which act in a synergistic manner. Synergistic combinations of drugs may prevent or postpone acquired resistance, thus increasing treatment efficiency. We cultured human ovarian carcinoma SKOV-3 and neuroblastoma NGP-127 cancer cell lines in the presence of Tyrosine Kinase Inhibitors (Pazopanib, Sorafenib, and Sunitinib) and Rapalogues (Temsirolimus and Everolimus) for four months and obtained cell lines demonstrating increased drug resistance. We investigated gene expression profiles of intact and resistant cells by microarrays and analyzed alterations in 378 cancer-related signaling pathways using the bioinformatical platform Oncobox. This revealed numerous pathways linked with development of drug resistant phenotypes. Our approach is based on targeting proteins involved in as many as possible signaling pathways upregulated in resistant cells. We tested 13 combinations of drugs and/or selective inhibitors predicted by Oncobox and 10 random combinations. Synergy scores for Oncobox predictions were significantly higher than for randomly selected drug combinations. Thus, the proposed approach significantly outperforms random selection of drugs and can be adopted to enhance discovery of new synergistic combinations of anticancer target drugs. PMID- 30274250 TI - The Benefit of Anti-Inflammatory and Renal-Protective Dietary Ingredients on the Biological Processes of Aging in the Kidney. AB - One of the significant organ systems which decline in aging is the kidney. While the causes of age-associated decline in renal function are likely multifactorial, oxidative stress and inflammation are hypothesized to play important roles in the structural and functional changes of the kidney. During aging there is a general decline in the glomerular filtration rate (GFR), a primary measurement used to assess kidney function. Inflammation and oxidative stress have been hypothesized to have a significant detrimental effect on renal function in aging and this may be attenuated by renal protective dietary ingredients. These dietary ingredients may affect renal function directly or through a microbiome-mediated secondary product. Likewise, structural changes including renal tubular atrophy, interstitial fibrosis, and glomerulosclerosis have all been described in aging. Such detrimental changes may benefit from dietary ingredients that may delay or attenuate the occurrence of such changes. This review will describe the physiology and pathophysiology of aging in renal function with an emphasis on dogs and cats that develop a decline in kidney function naturally. In addition, the varying biomarkers of health and renal dysfunction will be discussed. Finally, we will evaluate the aid in the management of this normal decline through dietary intervention in animal models. PMID- 30274249 TI - eB4CAST: An Evidence-Based Tool to Promote Dissemination and Implementation in Community-Based, Public Health Research. AB - eB4CAST, evidence-Based forecast C-capture, A-assemble, S-sustain, T-timelessness (eB4CAST), framework was developed from existing dissemination and implementation (D & I) constructs as a dissemination tool to promote community-based program usability and future application in targeted populations. eB4CAST captures and transforms research findings into a dissemination report that shows program need and impact to endorse program continuation and expansion. This is achieved through direct and indirect data collection of community factors and program impact that can showcase the need for program sustainability and potential for future dissemination sites. Testimonials, individual feedback, and program process and outcomes contribute to the direct data while data collected from census, county, and state databases and reports allow for indirect information to be captured and analyzed. Capturing data in the two levels allow eB4CAST to forecast program need and highlight program impact through a footprint. eB4CAST framework for dissemination tool creation is organized into four sections: Capture, Assemble, Sustainability, and Timelessness. Capture encompasses the collection of indirect and direct data related to intervention goals. Assemble is the compilation of the data into a visually appealing and easily understood media. Sustainability encourages the use of dissemination tools to provide forecast of program need and footprint of program impact back to community participants, program leaders, and key stakeholders to endorse program sustainability. Lastly, timelessness encourages cyclic movement through these constructs to continue program monitoring and data sharing to ensure timeless program evaluation and conformation to change in needs. The eB4CAST framework provides a systematic method to capture justification of program need and impact of community-based research that can be modified to fit diverse public health interventions providing a necessary D & I tool. PMID- 30274252 TI - Relationship of Absolute and Relative Lower-Body Strength to Predictors of Athletic Performance in Collegiate Women Soccer Players. AB - The purpose of this study was to investigate the relationships between absolute and relative lower-body strength on predictors of athletic performance among Division II collegiate women's soccer players. Archived pre-season testing data for seventeen (n = 17) female National Collegiate Athletics Association (NCAA) Division II soccer players were analyzed, including: vertical jump, 3RM back squat, 505-agility, modified T-test, 10 m and 30 m sprint, and 20 m multistage fitness test (20 m MSFT). Relative strength was calculated based on the estimated 1RM back squat divided by the athlete's body mass. Significant correlations were discovered between absolute lower-body strength and 505-agility (Right: r = 0.51, p < 0.05; Left: r = -0.59, p < 0.05), modified T-test (r = -0.55, p < 0.05), 10 m and 30 m (r = -0.59, p < 0.05; r = -0.54, p < 0.05), and sprint performance. Relative lower-body strength showed significant correlations with vertical jump (r = 0.54, p < 0.05), 505-agility (Right: r = -0.58, p < 0.05; Left: r = -0.67, p < 0.01), modified T-test (r = -0.75, p < 0.01), 10 m and 30 m (r = -0.59 p < 0.05; r = -0.67, p < 0.01), and the 20 m MSFT (r = 0.58, p < 0.05). These results indicate that strength and conditioning coaches should emphasize the development of absolute and relative lower-body strength with their players to improve power, agility, and speed performance.

AB - Sickle cell disease (SCD) is a genetic disorder resulting from the presence of mutated hemoglobin S (HbS). Homozygous carriers will present with early manifestations of painful vaso-occlusive crises. SCD patients have been reported to be severely deficient in vitamin D (<20 ng/mL). Four years (2010-2014) of individual de-identified Sickle Cell Clinic of Southern Louisiana (SCCSL-SCD) patient records were analyzed for vitamin D status and the level of crisis related ER/hospital utilization. To determine the dietary, and behavioral mediators of SCD-crisis in our study population, a cohort of 102 SCCSL-SCD patients were administered a survey that evaluated sun exposure, dietary behaviors, and pain frequency and severity. Patients with circulating levels of 25(OH)D3 less than 14.1 ng/mL reported having more crisis-related hospital visits per year (10) than patients with 25(OH)D3 serum levels >34 ng/mL. The result of the dietary survey detailed a relationship between patients who reported to have "Almost Never" consumed fish or milk in their diets and more frequent hospital stays and ER visits than those who reported consuming these products on a daily basis. Those who consumed these foods in their diet several times a month also had fewer ER visits when compared to the "Almost Never" category. PMID- 30274254 TI - Quantification and Confirmation of Fifteen Carbamate Pesticide Residues by Multiple Reaction Monitoring and Enhanced Product Ion Scan Modes via LC-MS/MS QTRAP System. AB - In this research, fifteen carbamate pesticide residues were systematically analyzed by ultra-high performance liquid chromatography-quadrupole-linear ion trap mass spectrometry on a QTRAP 5500 system in both multiple reaction monitoring (MRM) and enhanced product ion (EPI) scan modes. The carbamate pesticide residues were extracted from a variety of samples by QuEChERS method and separated by a popular reverse phase column (Waters BEH C18). Except for the current conformation criteria including selected ion pairs, retention time and relative intensities from MRM scan mode, the presence of carbamate pesticide residues in diverse samples, especially some doubtful cases, could also be confirmed by the matching of carbamate pesticide spectra via EPI scan mode. Moreover, the fragmentation routes of fifteen carbamates were firstly explained based on the mass spectra obtained by a QTRAP system; the characteristic fragment ion from a neutral loss of CH3NCO (-57 Da) could be observed. The limits of detection and quantification for fifteen carbamates were 0.2-2.0 MUg kg-1 and 0.5 5.0 MUg kg-1, respectively. For the intra- (n = 3) and inter-day (n = 15) precisions, the recoveries of fifteen carbamates from spiked samples ranged from 88.1% to 118.4%, and the coefficients of variation (CVs) were all below 10%. The method was applied to pesticide residues detection in fruit, vegetable and green tea samples taken from local markets, in which carbamates were extensively detected but all below the standard of maximum residue limit. PMID- 30274251 TI - Role of Mitogen Activated Protein Kinase Signaling in Parkinson's Disease. AB - Parkinson's disease (PD) is a neurodegenerative disorder caused by insufficient dopamine production due to the loss of 50% to 70% of dopaminergic neurons. A shortage of dopamine, which is predominantly produced by the dopaminergic neurons within the substantia nigra, causes clinical symptoms such as reduction of muscle mass, impaired body balance, akinesia, bradykinesia, tremors, postural instability, etc. Lastly, this can lead to a total loss of physical movement and death. Since no cure for PD has been developed up to now, researchers using cell cultures and animal models focus their work on searching for potential therapeutic targets in order to develop effective treatments. In recent years, genetic studies have prominently advocated for the role of improper protein phosphorylation caused by a dysfunction in kinases and/or phosphatases as an important player in progression and pathogenesis of PD. Thus, in this review, we focus on the role of selected MAP kinases such as JNKs, ERK1/2, and p38 MAP kinases in PD pathology. PMID- 30274256 TI - Emerging Functions for Cell Wall Polysaccharides Accumulated during Eudicot Seed Development. AB - The formation of seeds is a reproductive strategy in higher plants that enables the dispersal of offspring through time and space. Eudicot seeds comprise three main components, the embryo, the endosperm and the seed coat, where the coordinated development of each is important for the correct formation of the mature seed. In addition, the seed coat protects the quiescent progeny and can provide transport mechanisms. A key underlying process in the production of seed tissues is the formation of an extracellular matrix termed the cell wall, which is well known for its essential function in cytokinesis, directional growth and morphogenesis. The cell wall is composed of a macromolecular network of polymers where the major component is polysaccharides. The attributes of polysaccharides differ with their composition and charge, which enables dynamic remodeling of the mechanical and physical properties of the matrix by adjusting their production, modification or turnover. Accordingly, the importance of specific polysaccharides or modifications is increasingly being associated with specialized functions within seed tissues, often through the spatio-temporal accumulation or remodeling of particular polymers. Here, we review the evolution and accumulation of polysaccharides during eudicot seed development, what is known of their impact on wall architecture and the diverse roles associated with these in different seed tissues. PMID- 30274255 TI - Antioxidant Activity and Phytochemical Characterization of Senecio clivicolus Wedd. AB - Antioxidant phytochemicals play a key role in oxidative stress control and in the prevention of related disorders, such as premature aging, degenerative diseases, diabetes, and cancer. The aim of this study was to investigate the potential antioxidant activity and the phytochemical profile of Senecio clivicolus Wedd., a perennial shrub, belonging to the Asteraceae family. Despite the wide interest of this family, this specie has not been investigated yet. S. clivicolus aerial parts were extracted with 96% ethanol. Then, the ethanol extract was fractionated by liquid/liquid extraction using an increasing solvents polarity. Total polyphenol and terpenoid contents were measured. Moreover, the antioxidant activity was evaluated by six different complementary in vitro assays. The Relative Antioxidant Capacity Index (RACI) was used to compare data obtained by different tests. The sample showing the highest RACI was subjected to characterization and quantitation of its phenolic composition using LC-MS/MS analysis. The ethyl acetate fraction, investigated by LC-MS/MS analysis, showed 30 compounds, most of them are chlorogenic acid and flavonoid derivatives. To the best of our knowledge, this is the first report about the evaluation of antioxidant activity and phytochemical profile of S. clivicolus, underlying the importance of this species as a source of health-promoting phytochemicals. PMID- 30274258 TI - Fyn Regulates Binding Partners of Cyclic-AMP Dependent Protein Kinase A. AB - The cAMP-dependent protein kinase A (PKA) is a serine/threonine kinase involved in many fundamental cellular processes, including migration and proliferation. Recently, we found that the Src family kinase Fyn phosphorylates the catalytic subunit of PKA (PKA-C) at Y69, thereby increasing PKA kinase activity. We also showed that Fyn induced the phosphorylation of cellular proteins within the PKA preferred target motif. This led to the hypothesis that Fyn could affect proteins in complex with PKA. To test this, we employed a quantitative mass spectrometry approach to identify Fyn-dependent binding partners in complex with PKA-C. We found Fyn enhanced the binding of PKA-C to several cytoskeletal regulators that localize to the centrosome and Golgi apparatus. Three of these Fyn-induced PKA interactors, AKAP9, PDE4DIP, and CDK5RAP2, were validated biochemically and were shown to exist in complex with Fyn and PKA in a glioblastoma cell line. Intriguingly, the complexes formed between PKA-C and these known AKAPs were dependent upon Fyn catalytic activity and expression levels. In addition, we identified Fyn-regulated phosphorylation sites on proteins in complex with PKA-C. We also identified and biochemically validated a novel PKA-C interactor, LARP4, which complexed with PKA in the absence of Fyn. These results demonstrate the ability of Fyn to influence the docking of PKA to specific cellular scaffolds and suggest that Fyn may affect the downstream substrates targeted by PKA. PMID- 30274257 TI - Photodynamic Inactivation of Herpes Simplex Viruses. AB - Herpes simplex virus (HSV) infections can be treated with direct acting antivirals like acyclovir and foscarnet, but long-term use can lead to drug resistance, which motivates research into broadly-acting antivirals that can provide a greater genetic barrier to resistance. Photodynamic inactivation (PDI) employs a photosensitizer, light, and oxygen to create a local burst of reactive oxygen species that inactivate microorganisms. The botanical plant extract OrthoquinTM is a powerful photosensitizer with antimicrobial properties. Here we report that Orthoquin also has antiviral properties. Photoactivated Orthoquin inhibited herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2) infection of target cells in a dose-dependent manner across a broad range of sub-cytotoxic concentrations. HSV inactivation required direct contact between Orthoquin and the inoculum, whereas pre-treatment of target cells had no effect. Orthoquin did not cause appreciable damage to viral capsids or premature release of viral genomes, as measured by qPCR for the HSV-1 genome. By contrast, immunoblotting for HSV-1 antigens in purified virion preparations suggested that higher doses of Orthoquin had a physical impact on certain HSV-1 proteins that altered protein mobility or antigen detection. Orthoquin PDI also inhibited the non-enveloped adenovirus (AdV) in a dose-dependent manner, whereas Orthoquin mediated inhibition of the enveloped vesicular stomatitis virus (VSV) was light independent. Together, these findings suggest that the broad antiviral effects of Orthoquin-mediated PDI may stem from damage to viral attachment proteins. PMID- 30274260 TI - School Demands and Coping Resources-Associations with Multiple Measures of Stress in Mid-Adolescent Girls and Boys. AB - Stress, and stress-related health complaints, are common among young people, especially girls. Since studies have shown that school demands are an important driver of stress in adolescents, identifying if school-based resources can protect against stress is highly relevant. The aim of this study was to analyse task-related demands and task-related coping resources as aspects of the school work environment of potential relevance for stress in mid-adolescent girls and boys. The data came from "The School Stress and Support study" (TriSSS) conducted among students in grades 8 and 9 (aged 14-16 years). Self-reports of demands, coping resources, stress, as well as recurrent pain, were collected through questionnaires (n = 411). A subsample of students (n = 191-198) also provided salivary samples, which were analysed for the stress marker cortisol. Linear (OLS) and binary logistic regression analyses showed that higher demands were associated with more perceived stress, a higher likelihood of recurrent pain, and a lower cortisol awakening response. Greater coping resources were associated with less perceived stress and a lower likelihood of recurrent pain, but there was no association with cortisol. The strength of the associations differed by gender. The findings suggest that schools can promote student wellbeing by providing clear and timely information and teacher support to the students, especially for boys. Identifying specific features of the schoolwork that give rise to stress and to modify these accordingly is also of importance, especially for girls. PMID- 30274261 TI - Microwave-Assisted Extraction of Phenolic Compounds from Melastoma sanguineum Fruit: Optimization and Identification. AB - A microwave-assisted extraction (MAE) technology optimized by response surface methodology (RSM) was established to extract phenolic compounds from the fruit of Melastoma sanguineum. The effects of solvent composition, ratio of solvent to material, temperature, time and microwave power on phenol yield were evaluated in single-factor tests. The three parameters exerting main impacts on phenol yield were further optimized by RSM. Under optimal extraction conditions (31.33% ethanol, solvent/material ratio of 32.21 mL/g, 52.24 degrees C, 45 min and 500 W), the total phenolic content was 39.02 +/- 0.73 mg gallic acid equivalent (GAE)/g dry weight (DW). This MAE method performed better in comparison with two conventional methods, those being maceration (25.79 +/- 1.03 mg GAE/g DW) and Soxhlet extraction (18.40 +/- 1.34 mg GAE/g DW), using lower process temperature, shorter irradiation time, and lower organic solvent consumption. In addition, five flavonoids (epicatechin gallate, epicatechin, rutin, pigallocatechin and quercetin) and two phenolic acids (protocatechuic acid and chlorogenic acid) in the extract were identified and quantified using UPLC-MS/MS. PMID- 30274259 TI - TIPE Family of Proteins and Its Implications in Different Chronic Diseases. AB - The tumor necrosis factor-alpha-induced protein 8-like (TIPE/TNFAIP8) family is a recently identified family of proteins that is strongly associated with the regulation of immunity and tumorigenesis. This family is comprised of four members, namely, tumor necrosis factor-alpha-induced protein 8 (TIPE/TNFAIP8), tumor necrosis factor-alpha-induced protein 8-like 1 (TIPE1/TNFAIP8L1), tumor necrosis factor-alpha-induced protein 8-like 2 (TIPE2/TNFAIP8L2), and tumor necrosis factor-alpha-induced protein 8-like 3 (TIPE3/TNFAIP8L3). Although the proteins of this family were initially described as regulators of tumorigenesis, inflammation, and cell death, they are also found to be involved in the regulation of autophagy and the transfer of lipid secondary messengers, besides contributing to immune function and homeostasis. Interestingly, despite the existence of a significant sequence homology among the four members of this family, they are involved in different biological activities and also exhibit remarkable variability of expression. Furthermore, this family of proteins is highly deregulated in different human cancers and various chronic diseases. This review summarizes the vivid role of the TIPE family of proteins and its association with various signaling cascades in diverse chronic diseases. PMID- 30274262 TI - METCAM/MUC18 Decreases the Malignant Propensity of Human Ovarian Carcinoma Cells. AB - METCAM/MUC18 is an integral membrane cell adhesion molecule (CAM) in the Ig-like gene super-family. It can carry out common functions of CAMs which is to perform intercellular interactions and interaction of cell with extracellular matrix in tumor microenvironment, to interact with various signaling pathways and to regulate general behaviors of cells. We and other two groups previously suggested that METCAM/MUC18 probably be utilized as a biomarker for predicting the malignant tendency of clinical ovarian carcinomas, since METAM/MUC18 expression appears to associate with the carcinoma at advanced stages. It has been further postulated to promote the malignant tendency of the carcinoma. However, our recent research results appear to support the conclusion that the above positive correlation is fortuitous; actually METCAM/MUC18 acts as a tumor and metastasis suppressor for the ovarian carcinoma cells. We also suggest possible mechanisms in the METCAM/MUC18-mediated early tumor development and metastasis of ovarian carcinoma. Moreover, we propose to employ recombinant METCAM/MUC18 proteins and other derived products as therapeutic agents to treat the ovarian cancer patients by decreasing the malignant potential of ovarian carcinoma. PMID- 30274263 TI - A Novel Naphthyridine Derivative, 3u, Induces Necroptosis at Low Concentrations and Apoptosis at High Concentrations in Human Melanoma A375 Cells. AB - Naphthyridine derivatives are a widely-used class of heterocycles due to their pharmacological activities. A novel compound (10-Methoxy-1,2,3,4 tetrahydrobenzo(g)(1,3) diazepino(1,2-a)-(1,8)naphthyridin-6-yl)(phenyl) methanone (named 3u), showed good anticancer activity in the human malignant melanoma cell line A375 via Thiazolyl Blue Tetrazolium Bromide (MTT) assay. After Western blotting confirmed, we found that 3u induces necroptosis at low concentrations and apoptosis at high concentrations via the upregulation of death receptors and scaffold protein in A375 cells. Furthermore, by combining 3u with the caspase inhibitor zVAD-fmk or Receptor Interacting Serine/Threonine Kinase 1 (RIP1) kinase inhibitor Necrostatin-1 (Nec-1), we found that the activity of caspase-8 was the crucial factor that determined whether either apoptosis or necroptosis occurred. The results indicate that 3u should be considered as a potential chemical substance for melanoma treatment. PMID- 30274265 TI - Effects of 3-Week Work-Matched High-Intensity Intermittent Cycling Training with Different Cadences on VO2max in University Athletes. AB - The aim of this study is to clarify the effects of 3-week work-matched high intensity intermittent cycling training (HIICT) with different cadences on the VO2max of university athletes. Eighteen university athletes performed HIICT with either 60 rpm (n = 9) or 120 rpm (n = 9). The HIICT consisted of eight sets of 20 s exercise with a 10 s passive rest between each set. The initial training intensity was set at 135% of VO2max and was decreased by 5% every two sets. Athletes in both groups performed nine sessions of HIICT during a 3-week period. The total workload and achievement rate of the workload calculated before experiments in each group were used for analysis. VO2max was measured pre- and post-training. After 3 weeks of training, no significant differences in the total workload and the achievement rate of the workload were found between the two groups. VO2max similarly increased in both groups from pre- to post-training (p = 0.016), with no significant differences between the groups (p = 0.680). These results suggest that cadence during HIICT is not a training variable affecting the effect of VO2max. PMID- 30274266 TI - A Joint Low-Power Cell Search and Frequency Tracking Scheme in NB-IoT Systems for Green Internet of Things. AB - As a dedicated communication protocol for Internet-of-Things, narrowband internet of things (NB-IoT) needs to establish the communication link rapidly and reduce retransmissions as much as possible to achieve low power consumption and stable performance. To achieve these targets, the low-power scheme of the initial cell search and frequency tracking is investigated in this paper. The cell search process can be subdivided into narrowband primary synchronization signal (NPSS) detection and narrowband secondary synchronization signal (NSSS) detection. We present an NPSS detection method whose timing metric is composed of symbol-wise autocorrelation and a dedicated normalization factor. After the detection of NPSS, the symbol timing and fractional frequency offset estimation is implemented in a resource-efficient way. NSSS detection is conducted in the frequency domain with a calculation-reduced algorithm based on the features of NSSS sequences. To compensate the accumulated frequency offset during uplink transmission, a pilot aided rapid frequency tracking algorithm is proposed. The simulation results of the proposed cell search scheme are outstanding in both normal coverage and extended coverage NB-IoT scenarios, and the accumulated frequency offset can be estimated with high efficiency. PMID- 30274267 TI - Analysis of DME/DME Navigation Performance and Ground Network Using Stretched Front-Leg Pulse-Based DME. AB - Global navigation satellite systems (GNSS) have become a primary navigation means for aircraft. However, the signal power of GNSS is very weak, and its service can be disrupted at any time when there is interference or jamming. For this reason, the Federal Aviation Administration (FAA) in the United States has recently chosen a distance measuring equipment (DME)-based aircraft navigation technique, called DME/DME, as an alternative aircraft navigation means for use by around 2030. The reason that the FAA plans to use DME/DME in such a short duration, by around 2030, is presumed to be because the ranging accuracy of DMEs is between 70 to 300 m, which is about 7 to 30 times worse than that of GNSS. Thus, a significant loss of positioning performance is unavoidable with current DMEs. To make DME/DME a more competent alternative positioning source, this paper proposes an advanced DME that could provide a ranging accuracy of around 30 m by employing a recently developed Stretched-Front-Leg (SFOL) pulse. The paper introduces optimal ground station augmentation algorithms that help to efficiently transform the current DME ground network to enable a DME/DME positioning accuracy of up to 0.3 nm or 92.6 m with a minimal number of new ground DME sites. The positioning performance and augmented ground network using the proposed SFOL pulse-based DME are evaluated in two regions which have distinct terrain conditions. PMID- 30274264 TI - HCMV Infection and Apoptosis: How Do Monocytes Survive HCMV Infection? AB - Human cytomegalovirus (HCMV) infection of peripheral blood monocytes plays a key role in the hematogenous dissemination of the virus to multiple organ systems following primary infection or reactivation of latent virus in the bone marrow. Monocytes have a short life span of 1-3 days in circulation; thus, HCMV must alter their survival and differentiation to utilize these cells and their differentiated counterparts-macrophages-for dissemination and long term viral persistence. Because monocytes are not initially permissive for viral gene expression and replication, HCMV must control host-derived factors early during infection to prevent apoptosis or programmed cell death prior to viral induced differentiation into naturally long-lived macrophages. This review provides a short overview of HCMV infection of monocytes and describes how HCMV has evolved to utilize host cell anti-apoptotic pathways to allow infected monocytes to bridge the 48-72 h viability gate so that differentiation into a long term stable mature cell can occur. Because viral gene expression is delayed in monocytes following initial infection and only occurs (begins around two to three weeks post infection in our model) following what appears to be complete differentiation into mature macrophages or dendritic cells, or both; virally encoded anti-apoptotic gene products cannot initially control long term infected cell survival. Anti-apoptotic viral genes are discussed in the second section of this review and we argue they would play an important role in long term macrophage or dendritic cell survival following infection-induced differentiation. PMID- 30274269 TI - Association between eNOS Gene Polymorphism (T786C and VNTR) and Sickle Cell Disease Patients in Ghana. AB - Endothelial nitric oxide synthase (eNOS) variants have been found to be associated with several vascular disorders as well as the pathogenesis of sickle cell disease (SCD) complications such as vaso-occlusive crises (VOC). Studies on eNOS gene variants among SCD patients are rare in Ghana and several other African countries. The current study aimed to determine a possible association between variants of the eNOS gene (variable number of tandem repeats in intron 4 and T786C) in SCD complications among Ghanaian patients. This was a cross-sectional study involving 89 HbSS patients with complications and 46 HbSS patients without complications. Genomic DNA was extracted from leukocytes in the buffy coat and separated from collected whole blood samples of the study participants. PCR amplification, followed by restriction fragment length polymorphism (RFLP) was used to genotype T786C (rs2070744) variants. Variable number of tandem repeats (VNTR) in intron 4 was genotyped by PCR and direct electrophoresis. There was a significant difference in the genotype frequency of the T786C variant between HbSS patients with complications and those without complications (p = 0.0165). However, there was no significant difference in the VNTR intron 4 variant of the eNOS gene between patients with complications and those without complications (p > 0.05). The study shows an association between the eNOS gene variant (T786C) and complications in SCD. PMID- 30274268 TI - Assessment of the Public Health Threats Posed by Vector-Borne Disease in the United Kingdom (UK). AB - In recent years, the known distribution of vector-borne diseases in Europe has changed, with much new information also available now on the status of vectors in the United Kingdom (UK). For example, in 2016, the UK reported their first detection of the non-native mosquito Aedes albopictus, which is a known vector for dengue and chikungunya virus. In 2010, Culex modestus, a principal mosquito vector for West Nile virus was detected in large numbers in the Thames estuary. For tick-borne diseases, data on the changing distribution of the Lyme borreliosis tick vector, Ixodes ricinus, has recently been published, at a time when there has been an increase in the numbers of reported human cases of Lyme disease. This paper brings together the latest surveillance data and pertinent research on vector-borne disease in the UK, and its relevance to public health. It highlights the need for continued vector surveillance systems to monitor our native mosquito and tick fauna, as well as the need to expand surveillance for invasive species. It illustrates the importance of maintaining surveillance capacity that is sufficient to ensure accurate and timely disease risk assessment to help mitigate the UK's changing emerging infectious disease risks, especially in a time of climatic and environmental change and increasing global connectivity. PMID- 30274271 TI - Impact of Age-Adjusted Charlson Comorbidity on Hospital Survival and Short-Term Outcome of Patients with Extracorporeal Cardiopulmonary Resuscitation. AB - Extracorporeal cardiopulmonary resuscitation (ECPR) has gradually come to be regarded as an effective therapy, but the hospital mortality rate after ECPR is still high and unpredictable. The present study tested whether age-adjusted Charlson comorbidity index (ACCI) can be used as an objective selection criterion to ensure the most efficient utilization of medical resources. Adult patients (age >= 18 years) receiving ECPR at our institution between 2006 and 2015 were included. Data regarding ECPR events and ACCI characteristics were collected immediately after the extracorporeal membrane oxygenation (ECMO) setup. Adverse events during hospitalization were also prospectively collected. The primary endpoint was survival to hospital discharge. The second endpoint was the short term (2-year) follow-up outcome. A total of 461 patients included in the study were grouped into low ACCI (ACCI 0-3) (240, 52.1%) and high ACCI (ACCI 4-13) (221, 47.9%) groups. The median ACCI was 2 (interquartile range (IQR): 1-3) and 5 (IQR: 4-7) for the low and high ACCI groups, respectively. Cardiopulmonary resuscitation (CPR)-to-ECMO duration was comparable between the groups (42.1 +/- 25.6 and 41.3 +/- 20.7 min in the low and high ACCI groups, respectively; p = 0.754). Regarding the hospital survival rate, 256 patients (55.5%) died on ECMO support. A total of 205 patients (44.5%) were successfully weaned off ECMO, but only 138 patients (29.9%) survived to hospital discharge (32.1% and 27.6% in low and high ACCI group, p = 0.291). Multivariate logistic regression analysis revealed CPR duration before ECMO run (CPR-to-ECMO duration) and a CPR cause of septic shock to be significant risk factors for hospital survival after ECPR (p = 0.043 and 0.014, respectively), whereas age and ACCI were not (p = 0.334 and 0.164, respectively). The 2-year survival rate after hospital discharge for the 138 hospital survivors was 96% and 74% in the low and high ACCI groups, respectively (p = 0.002). High ACCI before ECPR does not predict a poor outcome of hospital survival. Therefore, ECPR should not be rejected solely due to high ACCI. However, high ACCI in hospital survivors is associated with a higher 2-year mortality rate than low ACCI, and patients with high ACCI should be closely followed up. PMID- 30274270 TI - Neighborhood Violence Impacts Disease Control and Surveillance: Case Study of Cali, Colombia from 2014 to 2016. AB - Arboviruses are responsible for a large burden of disease globally and are thus subject to intense epidemiological scrutiny. However, a variable notably absent from most epidemiological analyses has been the impact of violence on arboviral transmission and surveillance. Violence impedes surveillance and delivery of health and preventative services and affects an individual's health-related behaviors when survival takes priority. Moreover, low and middle-income countries bear a disproportionately high burden of violence and related health outcomes, including vector borne diseases. To better understand the epidemiology of arboviral outbreaks in Cali, Colombia, we georeferenced chikungunya (CHIKV), dengue (DENV), and Zika (ZIKV) viral cases from The National System of Surveillance in Public Health between October 2014 and April 2016. We extracted homicide data from the municipal monthly reports and kernel density of homicide distribution from IdeasPaz. Crucially, an overall higher risk of homicide is associated with increased risk of reported DENV, lower rates of acute testing, and higher rates of lab versus clinical discordance. In the context of high violence as a potential barrier to access to preventive health services, a community approach to improve health and peace should be considered. PMID- 30274272 TI - Impact of Different Estimation Methods on Obesity-Attributable Mortality Levels and Trends: The Case of The Netherlands. AB - The available methodologies to estimate the obesity-attributable mortality fraction (OAMF) affect the levels found and hamper the construction of time series. Our aim was to assess the impact of using different techniques to estimate the levels and the trends in obesity-attributable mortality for The Netherlands between 1981 to 2013. Using Body Mass Index (BMI), all-cause and cause-specific mortality data, and worldwide and European relative risks (RRs), we estimated OAMFs using three all-cause approaches (partially adjusted, weighted sum, and the two combined) and one cause-of-death approach (Comparative Risk Assessment; CRA). We adjusted the CRA approach to purely capture obesity (BMI >= 30 kg/m2). The different approaches led to a range of estimates. The weighted sum method using worldwide RRs generated the lowest (0.9%) while the adjusted CRA approach using 2013 RRs generated the highest estimate (1.5%). Using European specific RRs instead of worldwide RRs resulted in higher estimates. Most of the approaches revealed an increasing OAMF over the period 1981 to 2013 especially from 1993 onwards except for the adjusted CRA approach among women. Estimates of OAMF levels and trends differed depending on the method applied. Given the limited available data, we recommend using the weighted-sum method to compare obesity-attributable mortality across European countries over time. PMID- 30274273 TI - Activation of a Raw Clay by Mechanochemical Process-Effects of Various Parameters on the Process Efficiency and Cementitious Properties. AB - The efficiency of the mechanochemical activation (MCA) is influenced by various process parameters as well as by the properties of the treated material. The main objective of this research was to optimize the MCA process, gaining enhancement of the chemical reactivity of a Swedish raw clay, which is going to be used as an alkali-activated cementitious binder. The effects of the amount of water, the filling ratio, the rotation speed, and the grinding duration on the amorphization degree were evaluated by X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). Generally, wet and dry processes showed an extensive amorphization of both kaolinite and muscovite minerals present in the studied clay. On the contrary, quartz was amorphized mainly by the wet grinding process. The efficiency of both dry and wet grinding processes was enhanced by the increased number of grinding media versus the amount of the activated material. However, longer processing times caused significant agglomeration while a higher rotational speed enhanced the amorphization. Preliminary tests have shown that alkali activation of the processed clays produced hardened samples. Furthermore, the increased amorphization corresponded to the increased compressive strength values. PMID- 30274275 TI - A Rationale for Mesoscopic Domain Formation in Biomembranes. AB - Cell plasma membranes display a dramatically rich structural complexity characterized by functional sub-wavelength domains with specific lipid and protein composition. Under favorable experimental conditions, patterned morphologies can also be observed in vitro on model systems such as supported membranes or lipid vesicles. Lipid mixtures separating in liquid-ordered and liquid-disordered phases below a demixing temperature play a pivotal role in this context. Protein-protein and protein-lipid interactions also contribute to membrane shaping by promoting small domains or clusters. Such phase separations displaying characteristic length-scales falling in-between the nanoscopic, molecular scale on the one hand and the macroscopic scale on the other hand, are named mesophases in soft condensed matter physics. In this review, we propose a classification of the diverse mechanisms leading to mesophase separation in biomembranes. We distinguish between mechanisms relying upon equilibrium thermodynamics and those involving out-of-equilibrium mechanisms, notably active membrane recycling. In equilibrium, we especially focus on the many mechanisms that dwell on an up-down symmetry breaking between the upper and lower bilayer leaflets. Symmetry breaking is an ubiquitous mechanism in condensed matter physics at the heart of several important phenomena. In the present case, it can be either spontaneous (domain buckling) or explicit, i.e., due to an external cause (global or local vesicle bending properties). Whenever possible, theoretical predictions and simulation results are confronted to experiments on model systems or living cells, which enables us to identify the most realistic mechanisms from a biological perspective. PMID- 30274274 TI - Antibiotics from Deep-Sea Microorganisms: Current Discoveries and Perspectives. AB - The increasing emergence of new forms of multidrug resistance among human pathogenic bacteria, coupled with the consequent increase of infectious diseases, urgently requires the discovery and development of novel antimicrobial drugs with new modes of action. Most of the antibiotics currently available on the market were obtained from terrestrial organisms or derived semisynthetically from fermentation products. The isolation of microorganisms from previously unexplored habitats may lead to the discovery of lead structures with antibiotic activity. The deep-sea environment is a unique habitat, and deep-sea microorganisms, because of their adaptation to this extreme environment, have the potential to produce novel secondary metabolites with potent biological activities. This review covers novel antibiotics isolated from deep-sea microorganisms. The chemical classes of the compounds, their bioactivities, and the sources of organisms are outlined. Furthermore, the authors report recent advances in techniques and strategies for the exploitation of deep-sea microorganisms. PMID- 30274276 TI - A Passive Tracking System Based on Geometric Constraints in Adaptive Wireless Sensor Networks. AB - Target tracking technologies in wireless sensor network (WSNs) environments fall into two categories: active and passive schemes. Unlike with the active positioning schemes, in which the targets are required to hold cooperative devices, the research on passive tracking, i.e., tracking device-free targets, has recently showed promise. In the WSN, device-free targets can be tracked by sensing radio frequency tomography (RFT) on the line-of-sight links (LOSLs). In this paper, we propose a passive tracking scheme exploiting both adaptive networking LOSL webs and geometric constraint methodology for tracking single targets, as well as multiple targets. Regarding fundamental knowledge, we firstly explore the spatial diversity technique for RFT detection in realistic situations. Then, we analyze the power consumption of the WSN and propose an adaptive networking scheme for the purpose of energy conservation. Instead of maintaining a fixed LOSL density, the proposed scheme can adaptively adjust the networking level to save energy while guaranteeing tracking accuracy. The effectiveness of the proposed scheme is evaluated with computer simulations. According to the results, it is observed that the proposed scheme can sufficiently reduce power consumption, while providing qualified tracking performance. PMID- 30274278 TI - A New Bias Error Prediction Model for High-Precision Transfer Alignment. AB - The purpose of this work was to study bias error in acceleration-based transfer alignment, which is probably caused by cross-correlation between the dynamic lever-arm and the linear motion of a ship. A new prediction model for the cross correlation-caused error is proposed in this paper. We adopt the Bernoulli-Euler Beam as a simplified ship hull-girder model to verify the existence of the cross correlation. Then, the mathematical mechanism and the prediction model of the bias error are deduced via the ordinary least squares theory. Three factors influence the bias error in the prediction model: the amplitude of the dynamic lever arm acceleration, the amplitude of the ship motion acceleration, and the cross-correlation between them. Simulation experiments are then conducted to test the influence of the factors. The results show that the mechanism analysis is reasonable, and the bias error prediction model is in agreement with the experimental results. Thus, the proposed prediction model has the potential to deduce the bias error in high-accuracy transfer alignment. PMID- 30274277 TI - Topical Delivery of Senicapoc Nanoliposomal Formulation for Ocular Surface Treatments. AB - Topical ophthalmologic treatments have been facing great challenges with main limitations of low drug bioavailability, due to highly integrative defense mechanisms of the eye. This study rationally devised strategies to increase drug bioavailability by increasing ocular surface residence time of drug-loaded nanoliposomes dispersed within thermo-sensitive hydrogels (Pluronic F-127). Alternatively, we utilized sub-conjunctival injections as a depot technique to localize nanoliposomes. Senicapoc was encapsulated and sustainably released from free nanoliposomes and hydrogels formulations in vitro. Residence time increased up to 12-fold (60 min) with 24% hydrogel formulations, as compared to 5 min for free liposomes, which was observed in the eyes of Sprague-Dawley rats using fluorescence measurements. Pharmacokinetic results obtained from flushed tears, also showed that the hydrogels had greater drug retention capabilities to that of topical viscous solutions for up to 60 min. Senicapoc also remained quantifiable within sub-conjunctival tissues for up to 24 h post-injection. PMID- 30274279 TI - Inhibition of TRPV1 Channel Activity in Human CD4+ T Cells by Nanodiamond and Nanoplatinum Liquid, DPV576. AB - Background: Transient receptor potential vanilloid (TRPV) channels act as sensors of pain, temperature, and other external stimuli. We have recently shown that DPV576, an aqueous mixture of nanodiamond (ND) and nanoplatinum (NP), can modulate the activity of TRPV on human primary keratinocytes, suggesting their potential as a possible pain modulator. Here, we sought to examine the effect of DPV576 in modulating the functions of human CD4+ T lymphocytes and whether the modulation is mediated via TRPV channels. Materials and methods: Human primary CD4+ T cells were activated with anti CD3/CD28 with and without DPV576 at 1:10 and 1:100 dilutions for 24 h in vitro. TRPV receptor expression (TRPV1 and TRPV4) on CD4+ T cells were examined by flow cytometry. The capacity of DPV576 to modulate the activity of TRPV1 agonist capsaicin in CD4+ T cells was also determined. Activation of CD4+ T cells was determined by production of cytokines TNF-alpha, IFN-gamma, and IL-10 using specific ELISA kits. Results: DPV576 treatment of CD4+ T cells that were activated with anti CD3/CD28 resulted in decreased expression of the TRPV1 channel, but had no effect on TRPV4. This was accompanied by decreased secretion of IFN-gamma and reduced expression of TRPV1 in capsaicin activated CD4+ T cells. In addition, DPV576 inhibited the capsaicin, induced the production of IFN-gamma, and enhanced the secretion of IL-10. Conclusion: We conclude that short term exposure to DPV576 inhibits the activity of TRPV1 channels in CD4+ T lymphocytes, which may suggest its possible beneficial use for pain management. PMID- 30274281 TI - Incorporation of PVDF Nanofibre Multilayers into Functional Structure for Filtration Applications. AB - Membranes are considered as a promising technology for separation and filtration processes. Here, novel polyvinylidene fluoride (PVDF) nanofibrous multilayer membranes were fabricated by wire-based industrial electrospinning equipment following by a lamination process. The lamination process was optimised under various applied temperature, force of lamination, and lamination time. Air permeability and burst-pressure tests were run to determine the optimum membranes for filtration application. The structures of the prepared membranes were characterised by scanning electron microscopy and pore-size analysis. The hydrophilic properties of the membranes were evaluated using water contact angle measurement, and the mechanical strength of the membranes was analysed. Air and water filtration tests were run to find the possible application of prepared membranes. The air filtration results showed that membranes had high filtration efficiencies: Over 99.00% for PM2.5, and PM0.1. The water filtration results indicated that permeability of the membranes changed from 288 to 3275 L/m2hbar. The successful preparation of such an interesting material may provide a new approach for the design and development of electrospun filter membranes. PMID- 30274280 TI - Bipolar Tumor-Associated Macrophages in Ovarian Cancer as Targets for Therapy. AB - Ovarian cancer, a rare but fatal disease, has been a challenging area in the field of gynecological cancer. Ovarian cancer is characterized by peritoneal metastasis, which is facilitated by a cross-talk between tumor cells and other cells in the tumor microenvironment (TME). In epithelial ovarian cancer, tumor associated macrophages (TAMs) constitute over 50% of cells in the peritoneal TME and malignant ascites, and are potential targets for therapy. Here, we review the bipolar nature of TAMs and the evolving strategies to target TAMs in ovarian cancer. PMID- 30274283 TI - Overview of Phase-Change Electrical Probe Memory. AB - Phase-change electrical probe memory has recently attained considerable attention owing to its profound potential for next-generation mass and archival storage devices. To encourage more talented researchers to enter this field and thereby advance this technology, this paper first introduces approaches to induce the phase transformation of chalcogenide alloy by probe tip, considered as the root of phase-change electrical probe memory. Subsequently the design rule of an optimized architecture of phase-change electrical probe memory is proposed based on a previously developed electrothermal and phase kinetic model, followed by a summary of the state-of-the-art phase-change electrical probe memory and an outlook for its future prospects. PMID- 30274282 TI - The Effects of Carbon Content on the Anisotropic Deformation Mechanism of Boron Carbide. AB - The effects of carbon content on the mechanical properties and deformation mechanisms of boron carbides were investigated by first-principles calculations, based on the density functional theory. The B12-CBC (13.33 at % C) and B10 C 2 P CC (28.75 at % C) were studied and then compared with the deformation of regular B11CP-CBC (20.0 at % C). The results show the B10 C 2 P -CC, which has the lowest carbon content, has the highest strength and hardness as well as the lowest toughness. With the increase of carbon content, the rhombohedral symmetry will be broken and the three-atoms chains will be replaced by diatomic carbon chains. These changes may have an influence on their anisotropic deformation mechanisms. For the B12-CBC, the destruction of icosahedra without bending three-atom chains causes structural failure for compression along the c axis; while for compression along the a axis, new B-B bonds are formed, causing an unrecoverable deformation; then it is gradually destroyed until full destruction. For the B10 C 2 P -CC, the anisotropic deformation mechanism is not obvious. For both loading directions, the breakage of B-CP bonds causes the stress to drop, suggesting that the structure is beginning to be destroyed. Finally, the icosahedra are fully destroyed, resulting in structural failure. PMID- 30274284 TI - Calibrating the Severity of Forest Defoliation by Pine Processionary Moth with Landsat and UAV Imagery. AB - The pine processionary moth (Thaumetopoea pityocampa Dennis and Schiff.), one of the major defoliating insects in Mediterranean forests, has become an increasing threat to the forest health of the region over the past two decades. After a recent outbreak of T. pityocampa in Catalonia, Spain, we attempted to estimate the damage severity by capturing the maximum defoliation period over winter between pre-outbreak and post-outbreak images. The difference in vegetation index (dVI) derived from Landsat 8 was used as the change detection indicator and was further calibrated with Unmanned Aerial Vehicle (UAV) imagery. Regression models between predicted dVIs and observed defoliation degrees by UAV were compared among five selected dVIs for the coefficient of determination. Our results found the highest R-squared value (0.815) using Moisture Stress Index (MSI), with an overall accuracy of 72%, as a promising approach for estimating the severity of defoliation in affected areas where ground-truth data is limited. We concluded with the high potential of using UAVs as an alternative method to obtain ground truth data for cost-effectively monitoring forest health. In future studies, combining UAV images with satellite data may be considered to validate model predictions of the forest condition for developing ecosystem service tools. PMID- 30274285 TI - Visualization of Tau-Tubulin Interaction in a Living Cell Using Bifluorescence Complementation Technique. AB - Tau is a neuron-specific microtubule-binding protein that stabilizes microtubules. It is generally thought that highly phosphorylated tau dissociates from microtubules and becomes insoluble aggregates, leading to neuronal degeneration. Due to the implication of tau aggregation in neurodegenerative disorders, including Alzheimer's disease, great efforts have been made to identify the tau aggregation process. However, tau interaction with tubulin during the aggregation process remains largely unknown. To scrutinize the tau tubulin interaction, we generated a cell model that enables visualization of the tau-tubulin interaction in a living cell using the Bifluorescence Complementation (BiFC) Technique. Upon diverse chemical stimulation that induced tau pathology, tau-tubulin BiFC cells showed significantly increased levels of BiFC fluorescence, indicating that tau aggregates together with tubulin. Our results suggest that tubulin should be considered as a key component in the tau aggregation process. PMID- 30274286 TI - An Underwater Time Reversal Communication Method Using Symbol-Based Doppler Compensation with a Single Sound Pressure Sensor. AB - Due to the significant multipath and Doppler effects in the underwater acoustic (UWA) channel, the quality of the received signal is degraded, which seriously affects the performance of UWA communication. The paper proposes a time reversal UWA communication method combined with a symbol-based Doppler compensation (SBDC) technique to solve those problems. A single element time reversal mirror (TRM) is used to realize channel equalization and mitigate the inter-symbol interference (ISI) resulting from multipath propagation. The SBDC technique is subsequently used to compensate Doppler effects in the received signal, thereby reducing the bit error rate (BER) and improving the communication performance. In order to verify the performance of the proposed communication method, some simulations with real sounding channels were performed. Moreover, a field UWA communication experiment was conducted in the Songhua River (Harbin, China). The UWA communication experiment achieves nearly error-free performance with a communication rate of 100 bit/s in the bandwidth of 2 kHz. The results of the experiment demonstrate the feasibility and robustness of the proposed UWA communication method. PMID- 30274287 TI - Neuromodulation for Pelvic and Urogenital Pain. AB - Chronic pain affecting the pelvic and urogenital area is a major clinical problem with heterogeneous etiology, affecting both male and female patients and severely compromising quality of life. In cases where pharmacotherapy is ineffective, neuromodulation is proving to be a potential avenue to enhance analgesic outcomes. However, clinicians who frequently see patients with pelvic pain are not traditionally trained in a range of neuromodulation techniques. The aim of this overview is to describe major types of pelvic and urogenital pain syndromes and the neuromodulation approaches that have been trialed, including peripheral nerve stimulation, dorsal root ganglion stimulation, spinal cord stimulation, and brain stimulation techniques. Our conclusion is that neuromodulation, particularly of the peripheral nerves, may provide benefits for patients with pelvic pain. However, larger prospective randomized studies with carefully selected patient groups are required to establish efficacy and determine which patients are likely to achieve the best outcomes. PMID- 30274288 TI - Pharmacokinetic and Metabolism Studies of 12-Riboside-Pseudoginsengenin DQ by UPLC-MS/MS and UPLC-QTOF-MSE. AB - Pharmacokinetic and metabolism studies of 12-riboside-pseudoginsengenin DQ (RPDQ), a novel ginsenoside with an anti-cancer effect, were carried out, aiming at discussing the characteristics of the ginsenoside with glycosylation site at C 12. In the pharmacokinetic analysis, we developed and validated a method by UPLC MS to quantify RPDQ in rat plasma. In the range of 5-1000 ng/mL, the assay was linear (R2 > 0.9966), with the LLOQ (lower limit of quantification) being 5 ng/mL. The LOD (limit of detection) was 1.5 ng/mL. The deviations of intra-day and inter-day, expressed as relative standard deviation (RSD), were <= 3.51% and <= 5.41% respectively. The accuracy, expressed as relative error (RE), was in the range -8.82~3.47% and -5.61~2.87%, respectively. The recoveries were in the range 85.66~92.90%. The method was then applied to a pharmacokinetic study in rats intragastrically administrated with 6, 12, and 24 mg/kg RPDQ. The results showed that RPDQ exhibited slow oral absorption (Tmax = 7.0 h, 7.5 h, and 7.0 h, respectively), low elimination (t1/2 = 12.59 h, 12.83 h, and 13.74 h, respectively) and poor absolute bioavailability (5.55, 5.15, and 6.08%, respectively). Moreover, the investigation of metabolites were carried out by UPLC-QTOF-MS. Thirteen metabolites of RPDQ were characterized from plasma, bile, urine, and feces of rats. Some metabolic pathways, including oxidation, acetylation, hydration, reduction, hydroxylation, glycine conjugation, sulfation, phosphorylation, glucuronidation, glutathione conjugation, and deglycosylation, were profiled. In general, both the rapid quantitative method and a good understanding of the characteristics of RPDQ in vivo were provided in this study. PMID- 30274289 TI - Solid-Phase Extraction of Polar Benzotriazoles as Environmental Pollutants: A Review. AB - Polar benzotriazoles are corrosion inhibitors with widespread use; they are environmentally characterized as emerging pollutants in the water system, where they are present in low concentrations. Various extraction methods have been used for their separation from various matrices, ranging from classical liquid-liquid extractions to various microextraction techniques, but the most frequently applied extraction technique remains the solid-phase extraction (SPE), which is the focus of this review. We present an overview of the methods, developed in the last decade, applied for the determination of benzotriazoles in aqueous and solid environmental samples. Several other matrices, such as human urine and plant material, are also considered in the text. The methods are reviewed according to the determined compounds, sample matrices, cartridges and eluents used, extraction recoveries and the achieved limits of quantification. A critical evaluation of the advantages and drawbacks of the published methods is given. PMID- 30274290 TI - Representation of the QM Subsystem for Long-Range Electrostatic Interaction in Non-Periodic Ab Initio QM/MM Calculations. AB - In QM/MM calculations, it is essential to handle electrostatic interactions between the QM and MM subsystems accurately and efficiently. To achieve maximal efficiency, it is convenient to adopt a hybrid scheme, where the QM electron density is used explicitly in the evaluation of short-range QM/MM electrostatic interactions, while a multipolar representation for the QM electron density is employed to account for the long-range QM/MM electrostatic interactions. In order to avoid energy discontinuity at the cutoffs, which separate the short- and long range QM/MM electrostatic interactions, a switching function should be utilized to ensure a smooth potential energy surface. In this study, we benchmarked the accuracy of such hybrid embedding schemes for QM/MM electrostatic interactions using different multipolar representations, switching functions and cutoff distances. For test systems (neutral and anionic oxyluciferin in MM (aqueous and enzyme) environments), the best accuracy was acquired with a combination of QM electrostatic potential (ESP) charges and dipoles and two switching functions (long-range electrostatic corrections (LREC) and Switch) in the treatment of long range QM/MM electrostatics. It allowed us to apply a 10A distance cutoff and still obtain QM/MM electrostatics/polarization energies within 0.1 kcal/mol and time-dependent density functional theory (TDDFT)/MM vertical excitation energies within 10-3 eV from theoretical reference values. PMID- 30274291 TI - Chemical Composition of Myrtle (Myrtus communis L.) Berries Essential Oils as Observed in a Collection of Genotypes. AB - Myrtle (Myrtus communis L.) is a shrub spontaneously growing in the Mediterranean area. The leaf and fruit content of essential oils and phenolic compounds justify the wide use of the plant as medicinal and aromatic. Because of overexploitation of wild plants, a domestication process is in progress in different regions and the influence of the genotype variability on the chemical composition of fruit essential oils may be useful to breeding programs. Consequently, the analysis performed on a selected group of candidate clones growing in the same field collection in Sardinia is the object of this report. Forty-seven selections provided fully ripe fruits for essential oil extraction by hydrodistillation and Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Only five candidate clones showed white fruits. The highest yield of essential oil was observed in the LAC31 genotype with 0.55 g.kg-1, while the samples BOS1, MON5, RUM4, RUM10, V4 and V8 showed values above 0.20 g.kg-1 and most of the genotypes under 0.10 g.kg-1. Geranyl acetate was the compound with the highest relative abundance. The second compound for relative abundance was the 1,8-cineole. Other compounds with high relative abundance were alpha-terpinyl acetate, methyleugenol, linalool, alpha terpineol, beta-caryophyllene, alpha-humulene, Trans-caryophyllene oxide, and humulene epoxide II. PMID- 30274292 TI - Investigation of the Effects of Purpose in Life, Grit, Gratitude, and School Belonging on Mental Distress among Chinese Emerging Adults. AB - Given the high prevalence of mental distress indicators, such as depression, among emerging adults, it is imperative to identify not only factors that place them at risk for mental distress, but also those that protect against it. This study tested the direct and indirect effects (via purpose in life) of gratitude, two aspects of grit (i.e., consistency of interest and perseverance of effort), and school belonging on three indicators of mental distress (i.e., depression, anxiety, and stress). A total of 468 Chinese university students (58.3% female), aged 18 to 27, in Macao, China responded to an anonymous questionnaire between April to May, 2016. As expected, all psychosocial factors were negatively associated with all three indicators of mental distress (r = -0.15 to -0.42, p < 0.05), with the exception of perseverance of effort, which had a significant, negative association with depression only. The results of path analysis showed that purpose in life significantly mediated the effect of school belonging and perseverance of effort on depression, whereas school belonging, gratitude, and consistency of interest all had direct effects on all three indicators of mental distress (p < 0.05). Our results also suggested that the two components of grit may have differential effects on mental distress among Chinese emerging adults. School-based programs should consider positive psychology interventions in Chinese populations. PMID- 30274293 TI - A Metabolomic-Based Evaluation of the Role of Commensal Microbiota throughout the Gastrointestinal Tract in Mice. AB - Commensal microbiota colonize the surface of our bodies. The inside of the gastrointestinal tract is one such surface that provides a habitat for them. The gastrointestinal tract is a long organ system comprising of various parts, and each part possesses various functions. It has been reported that the composition of intestinal luminal metabolites between the small and large intestine are different; however, comprehensive metabolomic and commensal microbiota profiles specific to each part of the gastrointestinal lumen remain obscure. In this study, by using capillary electrophoresis time-of-flight mass spectrometry (CE TOFMS)-based metabolome and 16S rRNA gene-based microbiome analyses of specific pathogen-free (SPF) and germ-free (GF) murine gastrointestinal luminal profiles, we observed the different roles of commensal microbiota in each part of the gastrointestinal tract involved in carbohydrate metabolism and nutrient production. We found that the concentrations of most amino acids in the SPF small intestine were higher than those in the GF small intestine. Furthermore, sugar alcohols such as mannitol and sorbitol accumulated only in the GF large intestine, but not in the SPF large intestine. On the other hand, pentoses, such as arabinose and xylose, gradually accumulated from the cecum to the colon only in SPF mice, but were undetected in GF mice. Correlation network analysis between the gastrointestinal microbes and metabolites showed that niacin metabolism might be correlated to Methylobacteriaceae. Collectively, commensal microbiota partially affects the gastrointestinal luminal metabolite composition based on their metabolic dynamics, in cooperation with host digestion and absorption. PMID- 30274295 TI - Paths for Improving Bevacizumab Available in 2018: The ADZT Regimen for Better Glioblastoma Treatment. AB - During glioblastoma treatment, the pharmaceutical monoclonal antibody to vascular endothelial growth factor A, bevacizumab, has improved the quality of life and delayed progression for several months, but has not (or only marginally) prolonged overall survival. In 2017, several dramatic research papers appeared that are crucial to our understanding of glioblastoma vis-a-vis the mode of action of bevacizumab. As a consequence of these papers, a new, potentially more effective treatment protocol can be built around bevacizumab. This is the ADZT regimen, where four old drugs are added to bevacizumab. These four drugs are apremilast, marketed to treat psoriasis, dapsone, marketed to treat Hansen's disease, zonisamide, marketed to treat seizures, and telmisartan, marketed to treat hypertension. The ancillary attributes of each of these drugs have been shown to augment bevacizumab. This paper details the research data supporting this contention. Phase three testing of AZDT addition to bevacizumab is required to establish safety and effectiveness before general use. PMID- 30274294 TI - Overexpression of PeHKT1;1 Improves Salt Tolerance in Populus. AB - Soil salinization is an increasingly serious threat that limits plant growth and development. Class I transporters of the high-affinity K+ transporter (HKT) family have been demonstrated to be involved in salt tolerance by contributing to Na+ exclusion from roots and shoots. Here, we isolated the PeHKT1;1 gene from hybrid poplar based on the sequences of the Populus trichocarpa genome. The full length PeHKT1;1 gene was 2173 bp, including a 1608 bp open reading frame (ORF) encoding 535 amino acids and containing eight distinct transmembrane domains. Multiple sequence alignment and phylogenetic analysis suggested that the PeHKT1;1 protein had a typical S-G-G-G signature for the P-loop domains and belonged to class I of HKT transporters. PeHKT1;1 transcripts were mainly detected in stem and root, and were remarkably induced by salt stress treatment. In further characterization of its functions, overexpression of PeHKT1;1 in Populus davidiana * Populus bolleana resulted in a better relative growth rate in phenotypic analysis, including root and plant height, and exhibited higher catalase (CAT), peroxidase (POD), and superoxide dismutase (SOD) activities than non-transgenic poplar under salt stress conditions. These observations indicated that PeHKT1;1 may enhance salt tolerance by improving the efficiency of antioxidant systems. Together, these data suggest that PeHKT1;1 plays an important role in response to salt stress in Populus. PMID- 30274297 TI - Impact of CMOS Pixel and Electronic Circuitry in the Performance of a Hartmann Shack Wavefront Sensor. AB - This work presents a numerical simulation of a Hartmann-Shack wavefront sensor (WFS) that assesses the impact of integrated electronic circuitry on the sensor performance, by evaluating a full detection chain encompassing wavefront sampling, photodetection, electronic circuitry and wavefront reconstruction. This platform links dedicated C algorithms for WFS to a SPICE circuit simulator for integrated electronics. The complete codes can be easily replaced in order to represent different detection or reconstruction methods, while the circuit simulator employs reliable models of either off-the-shelf circuit components or custom integrated circuit modules. The most relevant role of this platform is to enable the evaluation of the applicability and constraints of the focal plane of a given wavefront sensor prior to the actual fabrication of the detector chip. In this paper, we will present the simulation results for a Hartmann-Shack wavefront sensor with an orthogonal array of quad-cells (QC) integrated along with active pixel (active-pixel sensor (APS)) circuitry and analog-to-digital converters (ADC) on a "complementary metal oxide semiconductor" (CMOS) process and deploying a modal wavefront reconstructor. This extended simulation capability for wavefront sensors enables the test and verification of different photosensitive and circuitry topologies for position-sensitive detectors combined with the simulation of sampling microlenses and reconstruction algorithms, with the goal of enhancing the accuracy in the prediction of the wavefront-sensor performance before a detector CMOS chip is actually fabricated.

AB - In this paper, a multifunctional biosensing platform for sensitively detecting Hg2+ and Ag+, based on ion-mediated base mismatch, fluorescent labeling, and strand displacement, is introduced. The sensor can also be used as an OR logic gate, the multifunctional design of sensors is realized. Firstly, orthogonal experiments with three factors and three levels were carried out on the designed sensor, and preliminary optimization of conditions was performed for subsequent experiments. Next, the designed sensor was tested the specificity and target selectivity under the optimized conditions, and the application to actual environmental samples further verified the feasibility. Generally, this is a convenient, fast, stable, and low-cost method that provides a variety of ideas and an experimental basis for subsequent research.

AB - Hierarchical CeO2 particles were synthesized by a hydrothermal method based on the reaction between CeCl3.7H2O and PVP at 270 degrees C. The flower-like CeO2 with an average diameter of about 1 MUm is composed of compact nanosheets with thicknesses of about 15 nm and have a surface area of 36.8 m2/g, a large pore volume of 0.109 cm3/g, and a narrow pore size distribution (14.9 nm in diameter). The possible formation mechanism of the hierarchical CeO2 nanoparticles has been illustrated. The 3D hierarchical structured CeO2 exhibited a higher catalytic activity toward CO oxidation compared with commercial CeO2. PMID- 30274298 TI - Association of Renal Function and Direct-Acting Antiviral Agents for HCV: A Network Meta-Analysis. AB - The effectiveness and safety of direct-acting antiviral agents (DAAs) in hepatitis C virus (HCV) patients with renal insufficiency remain controversial. Therefore, this network meta-analysis aims to assess effectiveness and safety of DAAs in populations with different renal function. The pooled data were obtained from Cochrane Library, EMBASE, PubMed, and Web of Science. Thirteen studies recruited 6884 patients with hepatitis C infection and reported their outcomes in relation to different levels of renal function after treatment with DAAs. The results showed no difference in the virologic responses among patients with different renal function. Regarding safety, whereas in patients without chronic kidney disease (CKD) or with early CKD DAAs were associated with a risk ratio (RR) of 0.14 (95% confidence interval (CI), 0.04 to 0.43) for renal disorder, increased risk of renal function deterioration was found in advanced-CKD patients, though this effect may be related to the natural course of advanced CKD. Similarly, patients without CKD or with early CKD showed a lower risk of anemia (RR, 0.34; 95% CI, 0.20 to 0.57) and discontinuation (RR, 0.41; 95% CI, 0.39 to 0.56) than patients with advanced CKD. The efficacy of DAAs for HCV treatment was comparable in patients with advanced CKD and in those with early CKD or without CKD. However, the safety of DAAs should be verified in future studies. PMID- 30274300 TI - A Label-Free Fluorescent AND Logic Gate Aptasensor for Sensitive ATP Detection. AB - In this study, a label-free fluorescent, enzyme-free, simple, highly sensitive AND logic gate aptasensor was developed for the detection of adenosine triphosphate (ATP). Double-stranded deoxyribonucleic acid (DNA) with cohesive ends was attached to graphene oxide (GO) to form an aptasensor probe. ATP and single-stranded DNA were used as input signals. Fluorescence intensity of PicoGreen dye was used as an output signal. The biosensor-related performances, including the logic gate construction, reaction time, linearity, sensitivity, and specificity, were investigated and the results showed that an AND logic gate was successfully constructed. The ATP detection range was found to be 20 to 400 nM (R2 = 0.9943) with limit of detection (LOD) of 142.6 pM, and the sensitivity range was 1.846 * 106 to 2.988 * 106 M-1. This method for the detection of ATP has the characteristics of being simple, low cost, and highly sensitive. PMID- 30274302 TI - Pattern of Paracetamol Poisoning: Influence on Outcome and Complications. AB - Acute paracetamol poisoning due to a single overdose may be effectively treated by the early administration of N-acetylcysteine (NAC) as an antidote. The prognosis may be different in the case of intoxication due to multiple ingestions or when the antidote is started with delay. The aim of this work was to investigate the outcome of paracetamol poisoning according to the pattern of ingestion and determine the factors associated with the outcome. We performed a retrospective analysis over the period 2007-2017 of the patients who were referred to a tertiary hospital for paracetamol-related hepatotoxicity. Inclusion criteria were: accidental or voluntary ingestion of paracetamol, delay for NAC therapy of 12 h or more, liver enzymes (ALT) >1000 IU/L on admission. Ninety patients were considered. Poisoned patients following multiple ingestion were significantly older (45 +/- 12 vs. 33 +/- 14) (p = 0.001), with a higher incidence of liver steatosis (p = 0.016) or chronic ethanol abuse (p = 0.04). In comparison with the subgroup of favorable outcome, the patients with poor outcome were older, had higher values for ALT, bilirubin, lactate, and lower values for factor V and arterial pH. In multivariate analysis, the arterial lactate value was associated with a bad prognosis (p < 0.02) (adjusted odds ratio 1.74 and CI 95:1.09-2.77). The risk of poor outcome was greater in the subgroup with staggered overdose (p = 0.02), which had a higher mortality rate (p = 0.01). This retrospective analysis illustrates the different population patterns of patients who were admitted for a single ingestion of a paracetamol overdose versus multiple ingestions. This last subgroup was mainly represented by older patients with additional risk factors for hepatotoxicity; arterial lactate was a good predictor of severity.

AB - The poor prognosis of pancreatic cancer requires the development of more effective therapy. CD147 expresses in pancreatic cancer with high incidence and has a crucial role in invasion and metastasis. We developed a fully human monoclonal antibody (059-053) with high affinity for CD147. Here we evaluated the efficacy of combined treatment using radioimmunotherapy (RIT) with 90Y-labeled 059-053 and gemcitabine in a BxPC-3 xenograft mouse model. Expression of CD147 and matrix metalloproteinase-2 (MMP2) in BxPC-3 tumors was evaluated. In vitro and in vivo properties of 059-053 were evaluated using 111In-labeled 059-053 and a pancreatic cancer model BxPC-3. Tumor volume and body weight were periodically measured in mice receiving gemcitabine, RIT, and both RIT and gemcitabine (one cycle and two cycles). High expression of CD147 and MMP2 was observed in BxPC-3 tumors and suppressed by 059-053 injection. Radiolabeled 059-053 bound specifically to BxPC-3 cells and accumulated highly in BxPC-3 tumors but low in major organs. Combined treatment using RIT with gemcitabine (one cycle) significantly suppressed tumor growth and prolonged survival with tolerable toxicity. The two-cycle regimen had the highest anti-tumor effect, but was not tolerable. Combined treatment with 90Y-labeled 059-053 and gemcitabine is a promising therapeutic option for pancreatic cancer. PMID- 30274303 TI - The Use of Video Instructions in Patient Education Promoting Correct Technique for Dry Powder Inhalers: An Investigation on Inhaler-Naive Individuals. AB - Introduction: The correct use of a prescribed inhaler device is crucial for achieving successful disease management in asthma. This study investigates non verbal, demonstrational videos as a method of teaching inhaler naive individuals how to use a dry powder inhaler (DPI). Methods: Video instructions for four DPIs were examined using a mixed methodology; 31 inhaler-naive individuals participated in the study. Participants were each shown a demonstrational video of one the four inhalers, after each video the participant demonstrated how they would use the inhaler. After demonstrating the use, participants crossed over to the next inhaler. The demonstrations were videotaped. A common questionnaire was filled at the beginning of the study and four inhaler-specific questionnaires which were filled out by the participant after each inhaler demonstration. Results: The frequency of participant error varied between inhalers. When asked about how they perceived the video instructions, participants often stated they would have liked to receive feedback on their performance. The importance of feedback was further highlighted by the fact that participants tended to overestimate their own inhaler technique. Conclusion: Non-verbal videos may be more efficient for some DPIs than for others as a method for providing inhaler instructions. Lack of feedback on the participants' inhaler performance emerged as a clear shortcoming of this educational method. Some steps in the inhalation process may be harder for individuals to remember and therefore require extra emphasis in order to achieve correct inhaler technique. PMID- 30274304 TI - MiR-205 Mediated Cu-Induced Lipid Accumulation in Yellow Catfish Pelteobagrus fulvidraco. AB - The present working hypothesis is that the Cu-induced changes in lipid metabolism may be mediated by miRNAs. Here, we describe the miRNA profile of the liver tissues of yellow catfish exposed to waterborne Cu, based on larger-scale sequencing of small RNA libraries. We identified a total of 172 distinct miRNAs. Among these miRNAs, compared to the control, mRNA expression levels of 16 miRNAs (miR-203a, 205, 1788-3p, 375, 31, 196a, 203b-3p, 2187-5p, 196d, 459-3p, 153a and miR-725, and two novel-miRNAs: chr4-1432, chr-7684) were down-regulated, and mRNA levels of miR-212 and chr20-5274 were up-regulated in Cu-exposed group. The functions of their target genes mainly involved ether lipid metabolism, glycerophospholipid metabolism, linoleic acid metabolism and alpha-linolenic acid metabolism. Cu exposure inhibited the expression of miR-205, whose predicted target genes were enriched in the pathway of lipid metabolism, including fas, lxralpha, ddit3, lamp2, casp3a and baxa. These potential target genes were further verified by Dual-luciferase reporter gene assay. Using primary hepatocytes of yellow catfish, Cu incubation down-regulated miR-205 expression, and increased TG contents and FAS activity. LXR antagonist effectively ameliorate the Cu-induced change of TG content and FAS activity. These data suggest that down-regulation of the miRNA-205 may be an important step in Cu-induced changes in lipid metabolism in yellow catfish. PMID- 30274305 TI - Botulinum Toxin in Restless Legs Syndrome-A Randomized Double-Blind Placebo Controlled Crossover Study. AB - BACKGROUND: Restless Legs Syndrome (RLS) is a common movement disorder with an estimated prevalence of up to 12%. Previous small studies with onabotulinumtoxin A (OnaA) for RLS have shown inconsistent results. METHODS: Twenty-four patients with an International RLS score (IRLS) of >11 (moderate-severe) were enrolled in this blinded, placebo-controlled crossover study. Twenty-one patients completed the evaluations at 4, 6, and 8 weeks after each injection. One-hundred units of Incobotulinumtoxin A (IncoA) or normal saline were injected into tibialis anterior, gastrocnemius, and biceps femoris muscles each side. RESULTS: Improvement from a severe (IRLS >21) to a mild/moderate (IRLS <=20) score was significant at four weeks (p = 0.0036) and six weeks (p = 0.0325) following IncoA administration compared to placebo. Additionally, there was significant improvement in pain score at six weeks as measured by Visual Analogue Scale (p = 0.04) and the Johns Hopkins Quality of Life Questionnaire (p = 0.01) in the IncoA group. Definite or marked improvement on Patient Global Impression of Change was seen in 7 out of 21 patients in the IncoA group vs. 1 out of 21 patients in the placebo group at 4 weeks (p = 0.012). CONCLUSION: IncoA injection lead to a reduction in severity of RLS symptoms, pain score, and quality of life, without any adverse effects. PMID- 30274307 TI - HCl Gas Sensor Coating Based on Poly(N-isopropylacrylamide) Nanoparticles Prepared from Water-Methanol Binary Solvent. AB - Poly(N-isopropylacrylamide) (PNIPAM) nanoparticles formed in water-methanol binary solvent were successfully deposited on a resonator surface at room temperature by exploiting the cononsolvency effect on the phase transition of PNIPAM aqueous solutions. Scanning electron microscopic observation revealed that the nanoparticles were secondary and made up of agglomerated primary spherical particles of about 10-nm diameter, buried in the film. The magnitude of the sensor response toward HCl gas was larger than that of the nanoparticle sensor prepared from pure water solvent, and the sensitivity to 1 ppm of HCl of sensor coated nanoparticles based on the present method was 3.3 Hz/ppm. The recovery of the sensors was less than 90% at first cycle measurement, but had improved to almost 100% at the third cycle. PMID- 30274306 TI - Photo-Magnetic Irradiation-Mediated Multimodal Therapy of Neuroblastoma Cells Using a Cluster of Multifunctional Nanostructures. AB - The use of high intensity chemo-radiotherapies has demonstrated only modest improvement in the treatment of high-risk neuroblastomas. Moreover, undesirable drug specific and radiation therapy-incurred side effects enhance the risk of developing into a second cancer at a later stage. In this study, a safer and alternative multimodal therapeutic strategy involving simultaneous optical and oscillating (AC) magnetic field stimulation of a multifunctional nanocarrier system has successfully been implemented to guide neuroblastoma cell destruction. This novel technique permitted the use of low-intensity photo-magnetic irradiation and reduced the required nanoparticle dose level. The combination of released cisplatin from the nanodrug reservoirs and photo-magnetic coupled hyperthermia mediated cytotoxicity led to the complete ablation of the B35 neuroblastoma cells in culture. Our study suggests that smart nanostructure-based photo-magnetic hybrid irradiation is a viable approach to remotely guide neuroblastoma cell destruction, which may be adopted in clinical management post modification to treat aggressive cancers. PMID- 30274309 TI - An Optimized Two-Step Magnetic Correction Strategy by Means of a Lagrange Multiplier Estimator with an Ellipsoid Constraint. AB - The geomagnetic field is as fundamental a constituent of passive navigation as Earth's gravity. In cases where no other external attitude reference is available, for the direct heading angle estimation by a typical magnetic compass, a two-step optimized correction algorithm is proposed to correct the model coefficients caused by hard and soft iron nearby. Specifically, in Step 1, a Levenberg-Marquardt (L-M) fitting estimator with an ellipsoid constraint is applied to solve the hard magnetic coefficients. In Step 2, a Lagrange multiplier estimator is used to deal with the soft magnetic iron circumstance. The essential attribute of "the two-step" lies in its eliminating the coupling effects of hard and soft magnetic fields, and their mutual interferences on the pure geomagnetic field. Under the conditions of non-deterministic magnetic interference sources with noise, the numerical simulation by referring to International Geomagnetic Reference Field (IGRF), and the laboratory tests based upon the turntable experiments with Honeywell HMR3000 compass (Honeywell, Morristown, NJ, USA) conducted, the experimental results indicate that, in the presence of the variation of multi-magnetic interferences, the RMSE (Root Mean Square Error) value of the estimated total magnetic flux density by the proposed two-step estimator falls to 0.125 MUT from its initial 2.503 MUT, and the mean values of the heading angle error estimates are less than 1 degrees . The proposed solution therefore, exhibits ideal convergent properties, fairly meeting the accuracy requirements of non-tactical level navigation applications. PMID- 30274308 TI - Humanin Attenuates NMDA-Induced Excitotoxicity by Inhibiting ROS-dependent JNK/p38 MAPK Pathway. AB - Humanin (HN) is a novel 24-amino acid peptide that protects neurons against N methyl-d-aspartate (NMDA)-induced toxicity. However, the contribution of the different mitogen-activated protein kinases (MAPKs) signals to HN neuroprotection against NMDA neurotoxicity remains unclear. The present study was therefore aimed to investigate neuroprotective mechanisms of HN. We analyzed intracellular Ca2+ levels, reactive oxygen species (ROS) production, and the MAPKs signal transduction cascade using an in vitro NMDA-mediated excitotoxicity of cortical neurons model. Results showed that: (1) HN attenuated NMDA-induced neuronal insults by increasing cell viability, decreasing lactate dehydrogenase (LDH) release, and increasing cell survival; (2) HN reversed NMDA-induced increase in intracellular calcium; (3) pretreatment by HN or 1,2-bis(2-aminophenoxy)ethane N,N,N',N'-tetraacetic acid (BAPTA-AM), an intracellular calcium chelator, decreased ROS generation after NMDA exposure; (4) administration of HN or N Acetyl-l-cysteine (NAC), a ROS scavenger, inhibited NMDA-induced JNK and p38 MAPK activation. These results indicated that HN reduced intracellular elevation of Ca2+ levels, which, in turn, inhibited ROS generation and subsequent JNK and p38 MAPK activation that are involved in promoting cell survival in NMDA-induced excitotoxicity. Therefore, the present study suggests that inhibition of ROS dependent JNK/p38 MAPK signaling pathway serves an effective strategy for HN neuroprotection against certain neurological diseases. PMID- 30274311 TI - Addition of Care for Transgender-Related Patient Care into Doctorate of Pharmacy Curriculum: Implementation and Preliminary Evaluation. AB - The number of transgender and gender-diverse patients seeking medical care in the United States is increasing. For many of these patients, pharmacotherapy is a part of their gender-affirming transition. Effective instructional methods and resources for teaching pharmacy students about this patient population's social considerations and medical treatments is lacking. Three hours of educational material on caring for transgender patients was added to a third-year course in a four-year Doctorate of Pharmacy program in the United States. The content included cultural, empathy, and medical considerations. Students in the course were given a survey to assess their perception of each instructional method's effectiveness and self-assess their confidence in providing competent gender affirming care to transgender people before and after the learning session. The survey response rate was 36% (54/152). Students' self-assessed confidence to provide competent care to people who are transgender increased significantly. Before the learning session, the median confidence level was 4/10 (Interquartile range (IQR) 3-6), after the class session, the median confidence increased to 7/10 (IQR 6-8, p < 0.01). Students rated the pre-class video, jeopardy game, and patient panel as most helpful to improving their skills. The addition of transgender-related patient care material into the Doctorate of Pharmacy curriculum significantly increased the students' confidence to provide competent care to people who are transgender. PMID- 30274310 TI - Current High-Throughput Approaches of Screening Modulatory Effects of Xenobiotics on Cytochrome P450 (CYP) Enzymes. AB - Cytochrome P450 (CYP) is a critical drug-metabolizing enzyme superfamily. Modulation of CYP enzyme activities has the potential to cause drug-drug/herb interactions. Drug-drug/herb interactions can lead to serious adverse drug reactions (ADRs) or drug failures. Therefore, there is a need to examine the modulatory effects of new drug entities or herbal preparations on a wide range of CYP isoforms. The classic method of quantifying CYP enzyme activities is based on high-performance liquid chromatography (HPLC), which is time- and reagent consuming. In the past two decades, high-throughput screening methods including fluorescence-based, luminescence-based, and mass-spectrometry-based assays have been developed and widely applied to estimate CYP enzyme activities. In general, these methods are faster and use lower volume of reagents than HPLC. However, each high-throughput method has its own limitations. Investigators may make a selection of these methods based on the available equipment in the laboratory, budget, and enzyme sources supplied. Furthermore, the current high-throughput systems should look into developing a reliable automation mechanism to accomplish ultra-high-throughput screening in the near future. PMID- 30274312 TI - Identifying Antibacterial Compounds in Black Walnuts (Juglans nigra) Using a Metabolomics Approach. AB - Black walnut (Juglans nigra L.) is one of the most economically valuable hardwood species and a high value tree for edible nut production in the United States. Although consumption of black walnut has been linked to multiple health-promoting effects (e.g., antioxidant, antimicrobial, anti-inflammatory), the bioactive compounds have not been systematically characterized. In addition, the associations between different black walnut cultivars and their health-promoting compounds have not been well established. In this study, the kernels of twenty two black walnut cultivars selected for nut production by the University of Missouri Center for Agroforestry (Columbia, MO, USA) were evaluated for their antibacterial activities using agar-well diffusion assay. Among the selected cultivars, four black walnut cultivars (i.e., Mystry, Surprise, D.34, and A.36) exhibited antibacterial activity against a Gram-positive bacterium (Staphylococcus aureus), whereas other cultivars showed no effect on the inhibition of this bacterium. The antibacterial compounds showing the strongest activity were isolated with bioassay-guided purification and identified using a metabolomics approach. Six antibacterial bioactive compounds responsible for antimicrobial activity were successfully identified. Glansreginin A, azelaic acid, quercetin, and eriodictyol-7-O-glucoside are novel antibacterial compounds identified in the kernels of black walnuts. The metabolomics approach provides a simple and cost-effective tool for bioactive compound identification. PMID- 30274313 TI - Molecular Scoring of Hepatocellular Carcinoma for Predicting Metastatic Recurrence and Requirements of Systemic Chemotherapy. AB - Hepatocellular carcinoma (HCC) causes one of the most frequent cancer-related deaths; an HCC subset shows rapid progression that affects survival. We clarify molecular features of aggressive HCC, and establish a molecular scoring system that predicts metastasis after curative treatment. In total, 125 HCCs were examined for TP53, CTNNB1, and TERT promoter mutation, methylation of 8 tumor suppressor genes, and 3 repetitive DNA sequences to estimate promoter hypermethylation and global hypomethylation. A fractional allelic loss (FAL) was calculated to represent chromosomal instability through microsatellite analysis. Molecular subclasses were determined using corresponding and hierarchical clustering analyses. Next, twenty-five HCC patients who underwent liver transplantation were analyzed for associations between molecular characteristics and metastatic recurrence; survival analyses were validated using a publicly available dataset of 376 HCC cases from the Cancer Genome Atlas (TCGA). An HCC subtype characterized by TP53 mutation, high FAL, and global hypomethylation was associated with aggressive tumor characteristics, like vascular invasion; CTNNB1 mutation was a feature of the less-progressive phenotype. A number of molecular risk factors, including TP53 mutation, high FAL, significant global hypomethylation, and absence of CTNNB1 mutation, were noted to predict shorter recurrence-free survival in patients who underwent liver transplantation (p = 0.0090 by log-rank test). These findings were validated in a cohort of resected HCC cases from TCGA (p = 0.0076). We concluded that molecular risks determined by common genetic and epigenetic alterations could predict metastatic recurrence after curative treatments, and could be a marker for considering systemic therapy for HCC patients. PMID- 30274315 TI - The Effect of Neonicotinoid Insecticide and Fungicide on Sugar Responsiveness and Orientation Behavior of Honey Bee (Apis mellifera) in Semi-Field Conditions. AB - Neonicotinoid insecticides are in widespread use around the world, cause pollinator decline. We used semi-field conditions to determine the effect of sublethal insecticide, thiamethoxam, exposure on orientation behavior and sugar responsiveness. Bees could not reject the non-treated flower or the insecticide or insecticide/fungicide treated flower. After bees consumed the insecticide or insecticide/fungicide treated nectar, they could not discriminate between a flower odor or blank control in a Y-maze when making a first choice. We also found that treated bees wander back and forth in both arms to make a final decision about food location, and used longer duration in the Y maze than the control group. Sugar responsiveness was also reduced after bees were fed with insecticide or insecticide/fungicide treated food, one week was needed for them to display the same level of responsiveness as the control group. The thiamethoxam or thiamethoxam/carbendazol treated crop field does not act as an olfactory repellent to the bee, but it does affect its post-consumption behavior. PMID- 30274314 TI - Anthocyanins Extracted from Oryza sativa L. Prevent Fluorouracil-Induced Nuclear Factor-kappaB Activation in Oral Mucositis: In Vitro and In Vivo Studies. AB - This study aims to investigate the immunomodulatory effect of anthocyanins (ANTs) from Oryza sativa L. extracts on 5-fluorouracil (5-FU)-induced oral mucositis, using a rat model and oral keratinocytes. ANTs were detected by high-performance liquid chromatography (HPLC)-electrospray ionization mass spectrometry. Animals were randomly given varying doses of ANT-rich extract treatment (500 mg/kg and 1000 mg/kg) in the absence or presence of 5-FU-induced mucositis. Buccal mucosae were photographed and scored for macroscopic analysis and incisional biopsies of cheek pouches were collected for microscopic examination of oral mucositis. 5-FU caused marked hemorrhage, extensive ulcerations and abscesses compared to non treated animals with slight erythema. Histologically, a loss of collagen bundles and inflammatory cell infiltrates was observed. After 29 days of ANT treatment, lesions resolved, and abundant collagen fibers were evident in the lamina propria. Buccal mucosa of 5-FU-injected rats showed increased Nuclear factor kappa B (NF-kappaB) p50 and p65 in oral keratinocytes. The administration of ANT reduced NF-kappaB-positive cells in 5-FU rats (p < 0.001) compared to the non treatment group. In oral keratinocytes, ANT treatment significantly restored 5-FU induced growth inhibition and impaired the nuclear accumulation of NF-kappaB p50 and p65. Our study demonstrated that ANT from Oryza sativa L. exhibited effective anti-inflammatory properties against 5-FU-induced oral mucositis by inhibiting NF kappaB activation. PMID- 30274316 TI - Phosphoric Acid Doped Polybenzimidazole (PBI)/Zeolitic Imidazolate Framework Composite Membranes with Significantly Enhanced Proton Conductivity under Low Humidity Conditions. AB - The preparation and characterization of composite polybenzimidazole (PBI) membranes containing zeolitic imidazolate framework 8 (ZIF-8) and zeolitic imidazolate framework 67 (ZIF-67) is reported. The phosphoric acid doped composite membranes display proton conductivity values that increase with increasing temperatures, maintaining their conductivity under anhydrous conditions. The addition of ZIF to the polymeric matrix enhances proton transport relative to the values observed for PBI and ZIFs alone. For example, the proton conductivity of PBI@ZIF-8 reaches 3.1 * 10-3 S.cm-1 at 200 degrees C and higher values were obtained for PBI@ZIF-67 membranes, with proton conductivities of up to 4.1 * 10-2 S.cm-1. Interestingly, a composite membrane containing a 5 wt.% binary mixture of ZIF-8 and ZIF-67 yielded a proton conductivity of 9.2 * 10-2 S.cm-1, showing a synergistic effect on the proton conductivity. PMID- 30274317 TI - PEGylation of Superparamagnetic Iron Oxide Nanoparticles with Self-Organizing Polyacrylate-PEG Brushes for Contrast Enhancement in MRI Diagnosis. AB - For biomedical applications, superparamagnetic nanoparticles (MNPs) have to be coated with a stealth layer that provides colloidal stability in biological media, long enough persistence and circulation times for reaching the expected medical aims, and anchor sites for further attachment of bioactive agents. One of such stealth molecules designed and synthesized by us, poly(polyethylene glycol methacrylate-co-acrylic acid) referred to as P(PEGMA-AA), was demonstrated to make MNPs reasonably resistant to cell internalization, and be an excellent candidate for magnetic hyperthermia treatments in addition to possessing the necessary colloidal stability under physiological conditions (Illes et al. J. Magn. Magn. Mater. 2018, 451, 710-720). In the present work, we elaborated on the molecular background of the formation of the P(PEGMA-AA)-coated MNPs, and of their remarkable colloidal stability and salt tolerance by using potentiometric acid-base titration, adsorption isotherm determination, infrared spectroscopy (FT IR ATR), dynamic light scattering, and electrokinetic potential determination methods. The P(PEGMA-AA)@MNPs have excellent blood compatibility as demonstrated in blood sedimentation, smears, and white blood cell viability experiments. In addition, blood serum proteins formed a protein corona, protecting the particles against aggregation (found in dynamic light scattering and electrokinetic potential measurements). Our novel particles also proved to be promising candidates for MRI diagnosis, exhibiting one of the highest values of r2 relaxivity (451 mM-1s-1) found in literature.

AB - We demonstrate a simple-to-fabricate refractometer based on the inscription of fiber Bragg gratings in a special C-shaped optical fiber. The C-shaped fiber was drawn into shape using a quarter cladding removed preform of a commercial standard single-mode fiber by simple machining. The sensor did not suffer from cross-sensitivity of the refractive index with ambient temperature fluctuations, commonly occurring with many optical fiber refractometers. A refractive index sensitivity of 1300 pm per refractive index unit (RIU) was achieved without employing any additional sensitization techniques such as tapering or etching. PMID- 30274320 TI - Study on the Classification, Causality, Preventability and Severity of Adverse Drug Reaction Using Spontaneous Reporting System in Hospitalized Patients. AB - Hospital-based adverse drug reaction (ADR) monitoring and reporting programs intend to identify and quantify the risks associated with the use of medicines. To examine the causality, preventability and severity of ADR in a hospital setting; a prospective cohort study on spontaneous ADR reporting was conducted from December 2015 to May 2016. Incidence of ADRs, causality, type, severity and preventability were assessed using necessary assessment scales. The study included 3157 hospitalized individuals, in whom 51 ADRs were detected among 49 patients. The overall incidence of suspected ADRs was found to be 1.6%. According to the causality assessment, most of the ADRs reported were probable (n = 26, 51.0%), and type A (augmented/pharmacological) reactions (n = 39, 76%) were the most common type of ADR found. The majority of ADRs were moderate to severe (n = 35, 68.6%), of which 37.3% were found to be potentially preventable. Predictability was observed in 28 (54.9%) reported ADRs. The prescribed medicines most frequently associated with ADRs were antibiotics, antiepileptics and antihypertensives. This feasibility study was able to highlight the clinical pharmacist's role in ADR monitoring service and create awareness about the way it could be done to promote safer medication use. Similar ADR reporting programs are necessary to educate and to improve awareness among healthcare professionals in some countries. PMID- 30274319 TI - Capillary Blood GSH Level Monitoring, Using an Electrochemical Method Adapted for Micro Volumes. AB - Glutathione (gamma-glutamyl-cysteinyl-glycine; also known as GSH) is an endogenous antioxidant that plays a crucial role in cell defense mechanisms against oxidative stress. It is thus not surprising that this molecule can serve as a biomarker for oxidative stress monitoring. As capillary blood is a highly accessible target for biomarking, it is a valuable bodily fluid for diagnosing human GSH levels. This study focused on the optimization of GSH measurements from micro volumes of capillary blood prior to using electrochemical detection. The optimization of experimental parameters, including the sample volume and its stability, was performed and evaluated. Moreover, we tested the optimized method as part of a short-term study. The study consisted of examining 10 subjects within 96 h of their consumption of high amounts of antioxidants, attained from a daily dose of 2 g/150 mL of green tea. The subjects' capillary blood (5 MUL) was taken at 0 h, 48 h, and 96 h for subsequent analysis. The short-term supplementation of diet with green tea showed an increase of GSH pool by approximately 38% (between 0 and 48 h) within all subjects. PMID- 30274321 TI - Correction: de Gonzalo, G.

PMID- 30274322 TI - Depression Negatively Impacts Survival of Patients with Metastatic Prostate Cancer. AB - The prevalence of depression in patients with cancer is high, especially for patients with advanced cancer. In this study, we evaluated the prevalence of depression in prostate cancer patients in Taiwan and the association between depression and mortality in prostate cancer. This study included 1101 newly diagnosed patients with prostate cancer. We tracked the medical information of these patients from diagnosis until the end of 2012. Patients were divided into two groups according to presence or absence of depression diagnosis, and were further divided into three stages by initial treatments: localized or locally advanced, metastatic, and castration-resistant prostate cancer. Of 1101 participants, 267 (24.3%) had depression. By the end of the follow-up period (M = 8.30 +/- 3.12 years), 77 (28.8%) patients in the depression group and 194 (23.3%) in the non-depressed group died. Depression was associated with higher mortality risk, (aHR 1.37; 95% CI [ 1.04-1.80]; p value 0.01). Patients in the metastatic prostate cancer group with depression had a significantly higher mortality risk compared to the non-depressed group, (aHR, 1.49; 95% CI [1.05-2.11]; p value 0.02). The impact of depression on mortality risk was not significant in either the localized or locally advanced or the castration-resistant prostate cancer groups. Our study showed that depression is related to an increased mortality risk for patients with prostate cancer, especially for metastatic prostate cancer. These results indicate that urologists should pay attention to the mood and psychiatric disorders of patients with prostate cancer. PMID- 30274324 TI - Biosynthesis of Grandione: An Example of Tandem Hetero Diels-Alder/Retro-Claisen Rearrangement Reaction? AB - Mechanistic theoretical studies about the feasibility of the traditional proposed mechanism of formation for icetexane diterpene dimer grandione were assessed using density functional method at the M06-2X/6-31G(d,p) level of theory. Bulk water solvent effects were taken into account implicitly using the polarizable continuum model (SCI-PCM). The results were compared with the selectivity found in the biomimetic synthesis performed by experimental research groups. The relative free energy calculation shows that the one-step H-DA formation mechanism nominated in the literature is not a viable mechanism. We found that an alternative competing Tandem pathway is consistent with the experimental trends. Thus, our results suggested that the compound grandione is formed via a H DA/retro-Claisen rearrangement and not by the traditional H-DA mechanism proposed early in the experimental studies. The H-DA initial step produce a biecyclic adduct followed by a domino retro-Claisen rearrangement that releases the energy strain of the bicyclic intermediary. Steric issues and hyperconjugation interactions are the mainly factors driving the reaction nature and the selectivity in the formation reaction. Finally, the enzymatic assistance for dimer formation was analyzed in terms of the calculated transition state energy barrier. PMID- 30274323 TI - Progress in Optimization of Agrobacterium-Mediated Transformation in Sorghum (Sorghum bicolor). AB - This review archives the achievements made in the last two decades and presents a brief outline of some significant factors influencing the Agrobacterium-mediated transformation of Sorghum bicolor. Recently, progress in successful transformation has been made for this particular monocot crop through direct DNA delivery method and indirect method via Agrobacterium. However, lower transformation rate still proved to be a bottleneck in genetic modification of sorghum. An efficient Agrobacterium transformation system could be attained by optimizing the preliminary assays, comprising of explant source, growth media, antibiotics, Agrobacterium strains and agro-infection response of callus. The selection of competent strains for genetic transformation is also one of the key factors of consideration. Successful transformation is highly dependent on genome configuration of selected cultivar, where non-tannin genotype proved the best suited. Immature embryos from the field source have higher inherent adaptation chances than that of the greenhouse source. A higher concentration of Agrobacterium may damage the explant source. Utilization of anti-necrotic treatments and optimized tissue culture timeframe are the adequate strategies to lower down the effect of phenolic compounds. Appropriate selection of culture media vessels at different stages of tissue culture may also assist in a constructive manner. In conclusion, some aspects such as culture environment with medium composition, explant sources, and genotypes play an indispensable role in successful Agrobacterium-mediated sorghum transformation system.

AB - Nonalcoholic fatty liver disease (NAFLD) is characterized by histological evidence of hepatic steatosis, lobular inflammation, ballooning degeneration and hepatic fibrosis in the absence of significant alcohol use and other known causes of chronic liver diseases. NAFLD is subdivided into nonalcoholic fatty liver (NAFL) and nonalcoholic steatohepatitis (NASH). NAFL is generally benign but can progress to NASH, which carries a higher risk of adverse outcomes including cirrhosis, end-stage liver disease, hepatocellular carcinoma and death if liver transplantation is not pursued in a timely fashion. Currently, lifestyle modifications including healthy diet and increased physical activity/exercise culminating in weight loss of 5% to >10% is the cornerstone of treatment intervention for patients with NAFLD. Patients with NAFLD who fail to obtain this goal despite the help of dietitians and regimented exercise programs are left in a purgatory state and remain at risk of developing NASH-related advance fibrosis. For such patients with NAFLD who are overweight and obese, healthcare providers should consider a trial of FDA-approved anti-obesity medications as adjunct therapy to provide further preventative and therapeutic options as an effort to reduce the risk of NAFLD-related disease progression. PMID- 30274325 TI - Dietary Fats and Chronic Noncommunicable Diseases. AB - The role of dietary fat has been long studied as a modifiable variable in the prevention and treatment of noncommunicable cardiometabolic disease. Once heavily promoted to the public, the low-fat diet has been demonstrated to be non effective in preventing cardiometabolic disease, and an increasing body of literature has focused on the effects of a relatively higher-fat diet. More recent evidence suggests that a diet high in healthy fat, rich in unsaturated fatty acids, such as the Mediterranean dietary pattern, may, in fact, prevent the development of metabolic diseases such as type 2 diabetes mellitus, but also reduce cardiovascular events. This review will specifically focus on clinical trials which collected data on dietary fatty acid intake, and the association of these fatty acids over time with measured cardiometabolic health outcomes, specifically focusing on morbidity and mortality outcomes. We will also describe mechanistic studies investigating the role of dietary fatty acids on cardiovascular risk factors to describe the potential mechanisms of action through which unsaturated fatty acids may exert their beneficial effects. The state of current knowledge on the associations between dietary fatty acids and cardiometabolic morbidity and mortality outcomes will be summarized and directions for future work will be discussed. PMID- 30274328 TI - Does Early Recruitment Predict Greater Physical Performance in Academy Soccer Players? AB - The purpose of this longitudinal study was to investigate whether recruitment status influences neuromuscular and endurance performances in academy soccer players over a 2-year training period (from Under-16 to Under-18). Thirty-seven male soccer players from an elite academy were selected and divided in two cohorts according to their recruitment status: Early Recruitment group (ER; n = 16), training and competing for the academy since Under-14 and Under-15 age groups, and; Late Recruitment group (LR; n = 21) included in the academy training process at Under-16. Squat (SJ) and countermovement jump with (CMJwA) and without arms swing (CMJ), 10-m sprint time, and Vam-Eval test (MAV) were performed in three successive occasions always pre-season (Under-16, Under-17 and Under-18 age groups, T1, T2, and T3 respectively). A two-way (recruitment status * time) analysis of variance with repeated measurements was performed as well as the magnitude of difference using both effect size and magnitude-based inferences. There was no difference between ER and LR for MAV, 10 m-sprint, and SJ from T1 to T3. However, LR players presented non-significant small and possibly greater improvement in CMJ (ES = 0.4) and CMJwA (ES = 0.4) than ER players at T2. These data indicate that early recruitment is not likely to result in greater physical performance improvement at the age of 18. PMID- 30274327 TI - The Acute Effects of Caffeinated Black Coffee on Cognition and Mood in Healthy Young and Older Adults. AB - Cognitive and mood benefits of coffee are often attributed to caffeine. However, emerging evidence indicates behavioural effects of non-caffeine components within coffee, suggesting the potential for direct or synergistic effects of these compounds when consumed with caffeine in regular brewed coffee. The current randomised, placebo-controlled, double-blind, counterbalanced-crossover study compared the effects of regular coffee, decaffeinated coffee, and placebo on measures of cognition and mood. Age and sex effects were explored by comparing responses of older (61-80 years, N = 30) and young (20-34 years, N = 29) males and females. Computerised measures of episodic memory, working memory, attention, and subjective state were completed at baseline and 30 min post-drink. Regular coffee produced the expected effects of decreased reaction time and increased alertness when compared to placebo. When compared to decaffeinated coffee, increased digit vigilance accuracy and decreased tiredness and headache ratings were observed. Decaffeinated coffee also increased alertness when compared to placebo. Higher jittery ratings following regular coffee in young females and older males represented the only interaction of sex and age with treatment. These findings suggest behavioural activity of coffee beyond its caffeine content, raising issues with the use of decaffeinated coffee as a placebo and highlighting the need for further research into its psychoactive effects. PMID- 30274329 TI - Prevalence and Clinical Significance of Symptoms at Ultra High Risk for Psychosis in Children and Adolescents with Obsessive-Compulsive Disorder: Is There an Association with Global, Role, and Social Functioning? AB - In literature nothing is known about the clinical significance of Ultra High Risk (UHR) symptoms in children and adolescents with diagnosis of obsessive-compulsive disorder (OCD). In this study, we examined the prevalence of UHR symptoms and their relationship with severity of obsessive-compulsive symptomatology, global, social, and role functioning, and level of associated depressive symptoms in a clinical sample (n = 51) of children and adolescents aged between 8 and 17 years with a diagnosis of OCD. The prevalence of UHR symptoms in this sample was 43.1%. We divided the whole sample into two groups: children and adolescents with OCD and UHR symptoms (n = 22) and children and adolescents with OCD without UHR symptoms (n = 29). Our findings suggest that the group with OCD and UHR symptoms shows worse global, social, and role functioning than the group with OCD without UHR symptoms. No differences were found on the severity of obsessive-compulsive symptomatology, the number of psychiatric diagnoses associated, and the level of depressive symptoms. The presence of UHR symptoms in children and adolescents with OCD could cause significant functional impairment and should be considered in order to plan specific and targeted therapeutic interventions. PMID- 30274330 TI - Photothermal Off-Resonance Tapping for Rapid and Gentle Atomic Force Imaging of Live Cells. AB - Imaging living cells by atomic force microscopy (AFM) promises not only high resolution topographical data, but additionally, mechanical contrast, both of which are not obtainable with other microscopy techniques. Such imaging is however challenging, as cells need to be measured with low interaction forces to prevent either deformation or detachment from the surface. Off-resonance modes which periodically probe the surface have been shown to be advantageous, as they provide excellent force control combined with large amplitudes, which help reduce lateral force interactions. However, the low actuation frequency in traditional off-resonance techniques limits the imaging speed significantly. Using photothermal actuation, we probe the surface by directly actuating the cantilever. Due to the much smaller mass that needs to be actuated, the achievable measurement frequency is increased by two orders of magnitude. Additionally, photothermal off-resonance tapping (PORT) retains the precise force control of conventional off-resonance modes and is therefore well suited to gentle imaging. Here, we show how photothermal off-resonance tapping can be used to study live cells by AFM. As an example of imaging mammalian cells, the initial attachment, as well as long-term detachment, of human thrombocytes is presented. The membrane disrupting effect of the antimicrobial peptide CM-15 is shown on the cell wall of Escherichia coli. Finally, the dissolution of the cell wall of Bacillus subtilis by lysozyme is shown. Taken together, these evolutionarily disparate forms of life exemplify the usefulness of PORT for live cell imaging in a multitude of biological disciplines. PMID- 30274331 TI - Radon in Schools: A Brief Review of State Laws and Regulations in the United States. AB - Exposure to Radon, a colorless, naturally occurring radioactive gas, is one of leading causes of lung cancer, and may pose a significant long-term risk for school age children. We examined the regulations and statutes in each US state related to radon in schools to delineate key features of policies and discrepancies among states that may have public health implications. Search terms such as "radon", "school", "mitigation", "certification", "licensing", and "radon resistant new construction" were used to scan current statutes from each state legislature's website and regulations from official state government websites for relevant regulatory and statutory requirements concerning radon in schools. State regulations related to the testing, mitigation, and public dissemination of radon levels in schools are inconsistent and the lack of nationwide indoor radon policy for schools may result in unacceptably high radon exposure levels in some US schools. We highlight the features and discrepancies of state laws and regulations concerning radon in schools, and offer several constructive means to reduce risks associated with radon exposure in school children. PMID- 30274332 TI - Main Allelochemicals from the Rhizosphere Soil of Saussurea lappa (Decne.) Sch. Bip. and Their Effects on Plants' Antioxidase Systems. AB - Allelochemicals are the media of allelopathy and form the chemical bases of plant environment interactions. To determine true allelochemicals and their autotoxic effects, seven compounds were isolated and identified from in-situ sampled rhizosphere soil of cultivated Saussurea lappa. Of these; costunolide (2), dehydrocostus lactone (3) and scopoletin (4) showed significant inhibition on seedling growth in a concentration-dependent manner. Detection and observation demonstrated that the antioxidase system was found to be affected by these chemicals, resulting in the accumulation of ROS and membrane damage. To investigate their release ways, the compounds were traced back and volumes quantified in rhizosphere soil and plant tissues. This work made clear the chemical bases and their physiological effects on the plants. These chemicals were found to be the secondary metabolites of the plants and included in the rhizosphere soil. The findings identified a potential pathway of plant-plant interactions, which provided theoretical basis to overcoming replanting problems. This research was also useful for exploring ecological effects of allelochemicals in green agriculture. PMID- 30274334 TI - Metabolomic Investigations on Nesterenkonia flava Revealed Significant Differences between Marine and Terrestrial Actinomycetes. AB - Marine microorganisms are an important source of natural products with potent bioactivities. Unlike the land, the ocean, especially the deep-sea, is characterized by high pressure, high salinity, low nutrition, and no light among others. Therefore, the biodiversity of marine microorganisms is supposed to be very different from that of the terrestrial ones. Yet, many marine microorganisms can find their counterparts in terrestrial environments. To evaluate their differences, a comparative metabolomics investigation was performed on four strains of Nesterenkonia flava isolated from terrestrial and marine environments. As a result, marine strains were clearly distinguished from terrestrial ones on the principal components analysis (PCA) score plot. Furthermore, by partial least squares discrimination analysis (PLS-DA) and univariate analysis, the characteristic metabolites were figured out and found to be involved in osmotic regulation, redox balancing, and energy metabolism. Our results demonstrated that marine actinomycetes could produce novel secondary metabolites different from their terrestrial relatives because they have special metabolic patterns closely related to the unique features of their living environment. PMID- 30274335 TI - An Experiment on the Psychological and Physiological Effects of Skin Moisturization on Lower Legs-In Expectation of Application to Nursing Practice at Hospitals. AB - This study hypothesized that moisturizing treatment of the skin has a positive effect on psychological and physiological aspects. In this experiment, the effect of touch with moisturizer for two minutes on the lower legs was measured in terms of brain activity, heart rate, and center of gravity unrest (X axis) in 10 healthy male and female experiment participants. The Right Laterality Ratio Score decreased after treatment, suggesting a relaxation effect of the treatment. Although it was not statistically significant, a decrease was observed. Heart rate decreased after the treatment at a level of statistical significance (p < 0.01), suggesting a relaxation effect of the treatment. Center of gravity unrest (X axis) increased after the treatment with statistical significance (p < 0.05). Therefore, skin moisturizing treatment was found to be effective both psychologically and physiologically in this experiment. The finding is expected to be applied to the field of nursing to support elderly people to enhance their mental well-being and balancing ability. PMID- 30274333 TI - Visualization of HIV-1 RNA Transcription from Integrated HIV-1 DNA in Reactivated Latently Infected Cells. AB - We have recently developed the first microscopy-based strategy that enables simultaneous multiplex detection of viral RNA (vRNA), viral DNA (vDNA), and viral protein. Here, we used this approach to study the kinetics of latency reactivation in cells infected with the human immunodeficiency virus (HIV). We showed the transcription of nascent vRNA from individual latently integrated and reactivated vDNA sites appearing earlier than viral protein. We further demonstrated that this method can be used to quantitatively assess the efficacy of a variety of latency reactivating agents. Finally, this microscopy-based strategy was augmented with a flow-cytometry-based approach, enabling the detection of transcriptional reactivation of large numbers of latently infected cells. Hence, these approaches are shown to be suitable for qualitative and quantitative studies of HIV-1 latency and reactivation. PMID- 30274336 TI - Effects of Conservative Tillage and Nitrogen Management on Weed Seed Bank after a Seven-Year Durum Wheat-Faba Bean Rotation. AB - Conservative agriculture includes a range of management strategies with low energy inputs such as no-tillage, minimum tillage, and low application of fertilizers. Weed flora in arable fields is strictly affected by agronomic practices such as tillage and fertilization management. This study was conducted seven years after the beginning of a long-term-durum wheat-faba bean-rotation. It analyzes the combined effects on the soil seed bank of three different tillage systems (conservative, reduced, and conventional tillage) and two levels of nitrogen fertilization. The effects were investigated both using stepwise discriminant analysis and analysis of variance in order to find statistical differences among main factors and their interactions. The seed bank of Conyza canadensis, Papaver rhoeas, Solanum nigrum, Fallopia convolvulus, and Fumaria officinalis was higher in conservative or reduced tillage plots. The magnitude of the response to nitrogen supply varied among weed species. Conyza canadensis seemed to be favored by low nitrogen supply, whereas Sinapis arvensis by higher doses of nitrogen. Anagallis arvensis showed the lowest seed bank in conventionally tilled plots, without distinction of nitrogen supply. The results suggest that different tillage systems and, to a lesser extent, different nitrogen supply, produce changes in the seed bank size and composition, along the soil profile. PMID- 30274337 TI - Gene Delivery into the Inner Ear and Its Clinical Implications for Hearing and Balance. AB - The inner ear contains many types of cell, including sensory hair cells and neurons. If these cells are damaged, they do not regenerate. Inner ear disorders have various etiologies. Some are related to aging or are idiopathic, as in sudden deafness. Others occur due to acoustic trauma, exposure to ototoxic drugs, viral infections, immune responses, or endolymphatic hydrops (Meniere's disease). For these disorders, inner ear regeneration therapy is expected to be a feasible alternative to cochlear implants for hearing recovery. Recently, the mechanisms underlying inner ear regeneration have been gradually clarified. Inner ear cell progenitors or stem cells have been identified. Factors necessary for regeneration have also been elucidated from the mechanism of hair cell generation. Inducing differentiation of endogenous stem cells or inner ear stem cell transplantation is expected. In this paper, we discuss recent approaches to hair cell proliferation and differentiation for inner ear regeneration. We discuss the future road map for clinical application. The therapies mentioned above require topical administration of transgenes or drug onto progenitors of sensory cells. Developing efficient and safe modes of administration is clinically important. In this regard, we also discuss our development of an inner ear endoscope to facilitate topical administration. PMID- 30274338 TI - Domain Adaptation and Adaptive Information Fusion for Object Detection on Foggy Days. AB - Foggy days pose many difficulties for outdoor camera surveillance systems. On foggy days, the optical attenuation and scattering effects of the medium significantly distort and degenerate the scene radiation, making it noisy and indistinguishable. Aiming to solve this problem, in this paper we propose a novel object detection method that has the ability to exploit the information in the color and depth domains. To prevent the error propagation problem, we clean the depth information before the training process and remove false samples from the database. A domain adaptation strategy is employed to adaptively fuse the decisions obtained in the color and depth domains. In the experiments, we evaluate the contribution of the depth information for object detection on foggy days. Moreover, the advantages of the multiple-domain adaptation strategy are experimentally demonstrated via comparison with other methods. PMID- 30274339 TI - A Unique Naphthone Derivative and a Rare 4,5-seco-Lanostane Triterpenoid from Poria cocos. AB - A previously undescribed naphthalenone derivative, sohiracillinone (1), and a novel 4,5-seco-lanostane triterpenoid, 11beta-ethoxydaedaleanic acid A (2) were isolated with two new lanostane triterpenoids, ceanphytamic acids A (3) and B (4), from the EtOH extract of Poria cocos along with 17 known compounds 5-21. The absolute configuration of sohiracillinone (1) was unambiguously identified by NMR and electronic circular dichroism (ECD) data. The structures of other new compounds were elucidated on the basis of NMR and mass spectroscopy (MS), and the cytotoxic activities of all the isolated components were evaluated. PMID- 30274340 TI - A Validation Study of Freezing of Gait (FoG) Detection and Machine-Learning-Based FoG Prediction Using Estimated Gait Characteristics with a Wearable Accelerometer. AB - One of the most common symptoms observed among most of the Parkinson's disease patients that affects movement pattern and is also related to the risk of fall, is usually termed as "freezing of gait (FoG)". To allow systematic assessment of FoG, objective quantification of gait parameters and automatic detection of FoG are needed. This will help in personalizing the treatment. In this paper, the objectives of the study are (1) quantification of gait parameters in an objective manner by using the data collected from wearable accelerometers; (2) comparison of five estimated gait parameters from the proposed algorithm with their counterparts obtained from the 3D motion capture system in terms of mean error rate and Pearson's correlation coefficient (PCC); (3) automatic discrimination of FoG patients from no FoG patients using machine learning techniques. It was found that the five gait parameters have a high level of agreement with PCC ranging from 0.961 to 0.984. The mean error rate between the estimated gait parameters from accelerometer-based approach and 3D motion capture system was found to be less than 10%. The performances of the classifiers are compared on the basis of accuracy. The best result was accomplished with the SVM classifier with an accuracy of approximately 88%. The proposed approach shows enough evidence that makes it applicable in a real-life scenario where the wearable accelerometer based system would be recommended to assess and monitor the FoG. PMID- 30274341 TI - Hits-to-Lead Optimization of the Natural Compound 2,4,6-Trihydroxy-3-geranyl acetophenone (tHGA) as a Potent LOX Inhibitor: Synthesis, Structure-Activity Relationship (SAR) Study, and Computational Assignment. AB - A new series of 2,4,6-trihydroxy-3-geranyl-acetophenone (tHGA) analogues were synthesized and evaluated for their lipoxygenase (LOX) inhibitory activity. Prenylated analogues 4a-g (half maximal inhibitory concentration (IC50) values ranging from 35 MU M to 95 MU M) did not exhibit better inhibitory activity than tHGA (3a) (IC50 value: 23.6 MU M) due to the reduction in hydrophobic interaction when the alkyl chain length was reduced. One geranylated analogue, 3d, with an IC50 value of 15.3 MU M, exhibited better LOX inhibitory activity when compared to tHGA (3a), which was in agreement with our previous findings. Kinetics study showed that the most active analogue (3e) and tHGA (3a) acted as competitive inhibitors. The combination of in silico approaches of molecular docking and molecular dynamic simulation revealed that the lipophilic nature of these analogues further enhanced the LOX inhibitory activity. Based on absorption, distribution, metabolism, excretion, and toxicity (ADMET) and toxicity prediction by komputer assisted technology (TOPKAT) analyses, all geranylated analogues (3a g) showed no hepatotoxicity effect and were biodegradable, which indicated that they could be potentially safe drugs for treating inflammation. PMID- 30274342 TI - Expression of a Grape VqSTS36-Increased Resistance to Powdery Mildew and Osmotic Stress in Arabidopsis but Enhanced Susceptibility to Botrytis cinerea in Arabidopsis and Tomato. AB - Stilbene synthase genes make a contribution to improving the tolerances of biotic and abiotic stress in plants. However, the mechanisms mediated by these STS genes remain unclear. To provide insight into the role of STS genes defense against biotic and abiotic stress, we overexpressed VqSTS36 in Arabidopsis thaliana and tomato (Micro-Tom) via Agrobacterium-mediated transformation. VqSTS36-transformed Arabidopsis lines displayed an increased resistance to powdery mildew, but both VqSTS36-transformed Arabidopsis and tomato lines showed the increased susceptibility to Botrytis cinerea. Besides, transgenic Arabidopsis lines were found to confer tolerance to salt and drought stress in seed and seedlings. When transgenic plants were treated with a different stress, qPCR assays of defense related genes in transgenic Arabidopsis and tomato suggested that VqSTS36 played a specific role in different phytohormone-related pathways, including salicylic acid, jasmonic acid, and abscisic acid signaling pathways. All of these results provided a better understanding of the mechanism behind the role of VqSTS36 in biotic and abiotic stress. PMID- 30274343 TI - New Layered Polythiophene-Silica Composite Through the Self-Assembly and Polymerization of Thiophene-Based Silylated Molecular Precursors. AB - A new layered hybrid polythiophene-silica material was obtained directly by hydrolysis and polycondensation (sol-gel) of a silylated-thiophene bifunctional precursor, and its subsequent oxidative polymerization by FeCl3. This precursor was judiciously designed to guarantee its self-assembly and the formation of a lamellar polymer-silica structure, exploiting the cooperative effect between the hydrogen bonding interactions, originating from the ureido groups and the pi stacking interactions between the thiophene units. The lamellar structure of the polythiophene-silica composite was confirmed by X-ray powder diffraction (XRD) and transmission electron microscopy (TEM) analyses. The solid-state nuclear magnetic resonance (NMR), UV-Vis, and photoluminescence spectra unambiguously indicate the incorporation of polythiophene into the silica matrix. Our work demonstrates that using a polymerizable silylated-thiophene precursor is an efficient approach towards the formation of nanostructured conjugated polymer based hybrid materials. PMID- 30274345 TI - Formation of alpha- and beta-Cembratriene-Diols in Tobacco (Nicotiana tabacum L.) Is Regulated by Jasmonate-Signaling Components via Manipulating Multiple Cembranoid Synthetic Genes. AB - Cembranoids are a group of natural diterpenoid compounds with pharmaceutical potentials, and the cembratriene-diols produced by Nicotiana (tobacco) species display activities in anti-nicotine addiction and neuron protection. Although the enzymes catalyzing cembratriene-diols' formation in tobacco have been investigated, the regulatory mechanism underlying this physiological process remains unknown. This study has investigated the roles of phytohormone jasmonic acid (JA) in regulating cembratriene-diol formation in N. tabacum cv. TN90 and found that JA and COI1, the receptor protein of the bioactive derivative of JA (i.e., JA-Ile), display critical roles in regulating cembratriene-diols' formation and the expression of cembranoid synthetic genes CBTS, P450 and NtLTP1. Further studies showed that over-expressing either the gene encoding bHLH transcription factor MYC2a or that encoding MYB transcription factor MYB305 could upregulate the cembranoid synthetic genes and enhance the cembranoid production in plants with dysfunction of COI1. Further studies suggest that COI1 and its downstream regulators MYC2a and MYB305 also modulate the trichome secretion, which is correlated with cembranoid formation. Taken together, this study has demonstrated a critical role of JA-signaling components in governing the cembratriene-diol formation and the transcription of cembratriene-diol synthetic genes in tobacco. Findings in this study are of great importance to reveal the molecular regulatory mechanism underlying cembranoid synthesis. PMID- 30274344 TI - A Comparison of a Pulse-Based Diet and the Therapeutic Lifestyle Changes Diet in Combination with Exercise and Health Counselling on the Cardio-Metabolic Risk Profile in Women with Polycystic Ovary Syndrome: A Randomized Controlled Trial. AB - : We compared the effects of a low-glycemic index pulse-based diet, containing lentils, beans, split peas, and chickpeas, to the Therapeutic Lifestyle Changes (TLC) diet on cardio-metabolic measures in women with polycystic ovary syndrome (PCOS). Ninety-five women (18-35 years) enrolled in a 16-week intervention; 30 women in the pulse-based and 31 in the TLC groups completed the study. Women participated in aerobic exercise training (minimum 5 days/week for 45 min/day) and were counselled (monthly) about PCOS and lifestyle modification. Women underwent longitudinal follow-up post-intervention. The pulse-based group had a greater reduction in total area under the curve for insulin response to a 75-g oral glucose tolerance test (mean change +/- SD: -121.0 +/- 229.9 vs. -27.4 +/- 110.2 uIU/mL * min; p = 0.05); diastolic blood pressure (-3.6 +/- 6.7 vs. -0.2 +/ 6.7 mmHg, p = 0.05); triglyceride (-0.2 +/- 0.6 vs. 0.0 +/- 0.5 mmol/L, p = 0.04); low-density lipoprotein cholesterol (-0.2 +/- 0.4 vs. -0.1 +/- 0.4 mmol/L, p = 0.05); total cholesterol/high-density lipoprotein cholesterol (TC/HDL-C; -0.4 +/- 0.4 vs. 0.1 +/- 0.4, p < 0.001); and a greater increase in HDL-C (0.1 +/- 0.2 vs. -0.1 +/- 0.2 mmol/L, p < 0.01) than the TLC group. Decreased TC/HDL-C (p = 0.02) at six-month and increased HDL-C and decreased TC/HDL-C (p <= 0.02) at 12 month post-intervention were maintained in the pulse-based group. A pulse-based diet may be more effective than the TLC diet at improving cardio-metabolic disease risk factors in women with PCOS. TRIAL REGISTRATION: CinicalTrials.gov identifier, NCT01288638. PMID- 30274347 TI - Wasabia koreana Nakai: A Preliminary Study on Nutrients and Chemical Compounds That May Impact Sensory Properties. AB - In this study, the nutritional, functional, and chemical measurements of sensory attributes of different parts of wasabi, namely, leaf, petiole, and rhizome, were investigated. Proximate composition analysis showed the presence of high amounts of carbohydrates in the rhizome and amino acid composition analysis confirmed high proportions of glutamic acid and aspartic acid in all three parts. While proximate composition showed low lipid content in wasabi, omega-3 fatty acids accounted for a high proportion (>44%) of the total lipids. Wasabi leaves had high vitamin C and total phenolic contents, and thus demonstrated antioxidant capacity. Allyl isothiocyanate, which gives wasabi its characteristic pungent taste, was identified by gas chromatography/mass spectrometry and an electronic nose. On an electronic tongue, wasabi leaves showed compounds associated with sourness and saltiness while the petiole had high content of compounds associated with sweetness and bitterness. This study provides basic data for the utilization of wasabi parts as food materials based on their nutritional, functional, and chemical measure of sensory attributes. PMID- 30274346 TI - LP1 from Lentinula edodes C91-3 Induces Autophagy, Apoptosis and Reduces Metastasis in Human Gastric Cancer Cell Line SGC-7901. AB - Present study aimed to elucidate the anticancer effect and the possible molecular mechanism underlying the action of Latcripin 1 (LP1), from the mushroom Lentinula edodes strain C91-3 against gastric cancer cell lines SGC-7901 and BGC-823. Cell viability was measured by Cell Counting Kit-8 (CCK-8); morphological changes were observed by phase contrast microscope; autophagy was determined by transmission electron microscope and fluorescence microscope. Apoptosis and cell cycle were assessed by flow cytometer; wound-healing, transwell migration and invasion assays were performed to investigate the effect of LP1 on gastric cancer cell's migration and invasion. Herein, we found that LP1 resulted in the induction of autophagy by the formation of autophagosomes and conversion of light chain 3 (LC3I into LC3II. LP1 up-regulated the expression level of autophagy-related gene (Atg7, Atg5, Atg12, Atg14) and Beclin1; increased and decreased the expression level of pro-apoptotic (Bax) and anti-apoptotic (Bcl-2) proteins respectively, along with the activation of Caspase-3. At lower-doses, LP1 have shown to arrest cells in the S phase of the cell cycle and decreased the expression level of matrix metalloproteinase MMP-2 and MMP-9. In addition, it has also been shown to regulate the phosphorylation of one of the most hampered gastric cancer pathway, that is, protein kinase B/mammalian target of rapamycin (Akt/mTOR) channel and resulted in cell death. These findings suggested LP1 as a potential natural anti cancer agent, for exploring the gastric cancer therapies and as a contender for further in vitro and in vivo investigations. PMID- 30274348 TI - A Quantum-Based Microwave Magnetic Field Sensor. AB - In this paper, a quantum-based method for measuring the microwave magnetic field in free space is presented by exploring atomic Rabi resonance in the clock transition of 133Cs. A compact cesium glass cell serving as the microwave magnetic field sensing head was used to measure the spatial distribution of microwave radiation from an open-ended waveguide antenna. The measured microwave magnetic field was not restricted by other microwave devices. The longitudinal distribution of the magnetic field was measured. The experimental results measured by the sensor were in agreement with the simulation. In addition, a slightly electromagnetic perturbation caused by the glass cell was investigated through simulation calculations. PMID- 30274349 TI - Seafarers' Quality of Life: Organizational Culture, Self-Efficacy, and Perceived Fatigue. AB - Using the Culture-Work-Health model, this study investigates the factors influencing the quality of life of seafarers. This study conducted a survey of 320 seafarers who have lived and worked on a ship for more than six months. This self-administered questionnaire included questions on organizational culture and support, self-efficacy, perceived fatigue, as well as the quality of work life. Organizational culture and self-efficacy were identified as factors affecting the quality of work life, while organizational support was found to have an indirect effect through self-efficacy and perceived fatigue. The final model accounts for 63.1% of the variance in seafarers' quality of life. As such, this study shows that self-efficacy is important for the quality of life of seafarers, having both direct and indirect effects. Moreover, organizational support may prove to be the primary intervention point for relieving perceived fatigue and enhancing self efficacy, thus improving the quality of work life. PMID- 30274351 TI - Respiratory Syncytial Virus Matrix (M) Protein Interacts with Actin In Vitro and in Cell Culture. AB - The virus-host protein interactions that underlie respiratory syncytial virus (RSV) assembly are still not completely defined, despite almost 60 years of research. RSV buds from the apical surface of infected cells, once virion components have been transported to the budding sites. Association of RSV matrix (M) protein with the actin cytoskeleton may play a role in facilitating this transport. We have investigated the interaction of M with actin in vitro and cell culture. Purified wildtype RSV M protein was found to bind directly to polymerized actin in vitro. Vero cells were transfected to express full-length M (1-256) as a green fluorescent protein-(GFP) tagged protein, followed by treatment with the microfilament destabilizer, cytochalasin D. Destabilization of the microfilament network resulted in mislocalization of full-length M, from mostly cytoplasmic to diffused across both cytoplasm and nucleus, suggesting that M interacts with microfilaments in this system. Importantly, treatment of RSV infected cells with cytochalasin D results in lower infectious virus titers, as well as mislocalization of M to the nucleus. Finally, using deletion mutants of M in a transfected cell system, we show that both the N- and C-terminus of the protein are required for the interaction. Together, our data suggest a possible role for M-actin interaction in transporting virion components in the infected cell.

AB - In order to improve the performance of storage and transmission of massive hyperspectral data, a prediction-based spatial-spectral adaptive hyperspectral compressive sensing (PSSAHCS) algorithm is proposed. Firstly, the spatial block size of hyperspectral images is adaptively obtained according to the spatial self correlation coefficient. Secondly, a k-means clustering algorithm is used to group the hyperspectral images. Thirdly, we use a local means and local standard deviations (LMLSD) algorithm to find the optimal image in the group as the key band, and the non-key bands in the group can be smoothed by linear prediction. Fourthly, the random Gaussian measurement matrix is used as the sampling matrix, and the discrete cosine transform (DCT) matrix serves as the sparse basis. Finally, the stagewise orthogonal matching pursuit (StOMP) is used to reconstruct the hyperspectral images. The experimental results show that the proposed PSSAHCS algorithm can achieve better evaluation results-the subjective evaluation, the peak signal-to-noise ratio, and the spatial autocorrelation coefficient in the spatial domain, and spectral curve comparison and correlation between spectra reconstructed performance in the spectral domain-than those of single spectral compression sensing (SSCS), block hyperspectral compressive sensing (BHCS), and adaptive grouping distributed compressive sensing (AGDCS). PSSAHCS can not only compress and reconstruct hyperspectral images effectively, but also has strong denoise performance.

AB - African savanna elephants live in dynamic fission-fusion societies and exhibit a sophisticated vocal communication system. Their most frequent call-type is the 'rumble', with a fundamental frequency (which refers to the lowest vocal fold vibration rate when producing a vocalization) near or in the infrasonic range. Rumbles are used in a wide variety of behavioral contexts, for short- and long distance communication, and convey contextual and physical information. For example, maturity (age and size) is encoded in male rumbles by formant frequencies (the resonance frequencies of the vocal tract), having the most informative power. As sound propagates, however, its spectral and temporal structures degrade progressively. Our study used manipulated and resynthesized male social rumbles to simulate large and small individuals (based on different formant values) to quantify whether this phenotypic information efficiently transmits over long distances. To examine transmission efficiency and the potential influences of ecological factors, we broadcasted and re-recorded rumbles at distances of up to 1.5 km in two different habitats at the Addo Elephant National Park, South Africa. Our results show that rumbles were affected by spectral-temporal degradation over distance. Interestingly and unlike previous findings, the transmission of formants was better than that of the fundamental frequency. Our findings demonstrate the importance of formant frequencies for the efficiency of rumble propagation and the transmission of information content in a savanna elephant's natural habitat.

AB - The intent of the present work was to evaluate the potential of four macroalgae prevalent in Europe, namely Ulva rigida, Gracilaria sp., Fucus vesiculosus and Saccharina latissima, for application in functional foods, either in the direct form or as extracts. Accordingly, nutritional composition, the content of phytochemical antioxidants, and the inhibitory ability of key enzymes with impacts on obesity and diabetes (alpha-glucosidase and pancreatic lipase) or on arterial pressure (angiotensin-I converting enzyme), were evaluated. Overall, protein, lipid, ash and fiber contents of the macroalgae ranged from 9-24% dw, 0.5-3.0% dw, 20-32% dw, and 37-45% dw, respectively, making them good candidates for nutritional supplementation of several foods, particularly due to their mineral and fiber contents. In addition, brown macroalgae, in particular F. vesiculosus, stood out for its superior phenolic content, which was reflected by its high antioxidant ability and inhibition towards alpha-glucosidase activity (0.032 mg/mL of hydroacetonic extract inhibited 50% of the enzyme activity). PMID- 30274354 TI - Anemia and Iron Deficiency in Cancer Patients: Role of Iron Replacement Therapy. AB - Anemia in cancer patients is quite common, with remarkable negative impacts on quality of life and overall prognosis. The pathogenesis is complex and typically multifactorial, with iron deficiency (ID) often being a major and potentially treatable contributor. In turn, ID in cancer patients can be due to multiple concurring mechanisms, including bleeding (e.g., in gastrointestinal cancers or after surgery), malnutrition, medications, and hepcidin-driven iron sequestration into macrophages with subsequent iron-restricted erythropoiesis. Indeed, either absolute or functional iron deficiency (AID or FID) can occur. While for absolute ID there is a general consensus regarding the laboratory definition (that is ferritin levels <100 ng/mL +/- transferrin saturation (TSAT) <20%), a shared definition of functional ID is still lacking. Current therapeutic options in cancer anemia include iron replacement, erythropoietic stimulating agents (ESAs), and blood transfusions. The latter should be kept to a minimum, because of concerns regarding risks, costs, and limited resources. Iron therapy has proved to be a valid approach to enhance efficacy of ESAs and to reduce transfusion need. Available guidelines focus mainly on patients with chemotherapy-associated anemia, and generally suggest intravenous (IV) iron when AID or FID is present. However, in the case of FID, the upper limit of ferritin in association with TSAT <20% at which iron should be prescribed is a matter of controversy, ranging up to 800 ng/mL. An increasingly recognized indication to IV iron in cancer patients is represented by preoperative anemia in elective oncologic surgery. In this setting, the primary goal of treatment is to decrease the need of blood transfusions in the perioperative period, rather than improving anemia-related symptoms as in chemotherapy-associated anemia. Protocols are mainly based on experiences of Patient Blood Management (PBM) in non-oncologic surgery, but no specific guidelines are available for oncologic surgery. Here we discuss some possible approaches to the management of ID in cancer patients in different clinical settings, based on current guidelines and recommendations, emphasizing the need for further research in the field. PMID- 30274355 TI - Prevention of Progression in Myopia: A Systematic Review. AB - The prevalence of myopia has increased worldwide in recent decades and now is endemic over the entire industrial world. This increase is mainly caused by changes in lifestyle and behavior. In particular, the amount of outdoor activities and near work would display an important role in the pathogenesis of the disease. Several strategies have been reported as effective. Spectacles and contact lenses have shown only slight results in the prevention of myopia and similarly ortokerathology should not be considered as a first-line strategy, given the high risk of infectious keratitis and the relatively low compliance for the patients. Thus, to date, atropine ophthalmic drops seem to be the most effective treatment for slowing the progression of myopia, although the exact mechanism of the effect of treatment is still uncertain. In particular, low-dose atropine (0.01%) was proven to be an effective and safe treatment in the long term due to the lowest rebound effect with negligible side effects. PMID- 30274356 TI - In Situ Investigation of Grain Evolution of 300M Steel in Isothermal Holding Process. AB - The relationships between initial microstructures, process parameters, and grain evolutions in isothermal holdings have drawn wide attention in recent years, but the grain growth behaviors of 300M steel were not well understood, resulting in a failure in precise microstructure controlling in heat treatment. In this work, in situ observations were carried out to characterize the grain evolutions of 300M steel with varying holding time, holding temperatures, and initial microstructures. The intriguing finding was that the grain refinement by austenization of 300M steel was followed by a dramatic grain growth in the initial stage of holding (<=~600 s), and with increasing time (~600-7200 s), the average grain size appeared to have a limit value at specific temperatures. The austenization process accelerated the grain growth by generating large quantity of grain boundaries at the initial stage of holdings, and the growth rate gradually slowed down after holding for ~600 s because the driven force was weakened due to the reduction of grain boundary energy. The initial structure and the initial grain size of 300M steel had no obvious influences on the grain size evolutions. The mechanisms of grain growth were analyzed based on in situ observations and transmission electron microscope (TEM) characterizations. A grain evolution model considering the grain boundary migration of 300M steel was established for the isothermal holding process. Good agreement was obtained between the in situ observation results and the model calculation results. This investigation aimed to understand fundamentally the grain evolutions of 300M steel in the isothermal holding process. PMID- 30274357 TI - Immunogenicity and Protective Activity of a Chimeric Protein Based on the Domain III of the Tick-Borne Encephalitis Virus E Protein and the OmpF Porin of Yersinia pseudotuberculosis Incorporated into the TI-Complex. AB - Tick-borne encephalitis (TBE) is a widespread, dangerous infection. Unfortunately, all attempts to create safe anti-TBE subunit vaccines are still unsuccessful due to their low immunogenicity. The goal of the present work was to investigate the immunogenicity of a recombinant chimeric protein created by the fusion of the EIII protein, comprising domain III and a stem region of the tick borne encephalitis virus (TBEV) E protein, and the OmpF porin of Yersinia pseudotuberculosis (OmpF-EIII). Adjuvanted antigen delivery systems, the tubular immunostimulating complexes (TI-complexes) based on the monogalactosyldiacylglycerol from different marine macrophytes, were used to enhance the immunogenicity of OmpF-EIII. Also, the chimeric protein incorporated into the most effective TI-complex was used to study its protective activity. The content of anti-OmpF-EIII antibodies was estimated in mice blood serum by enzyme linked immunosorbent assay (ELISA). To study protective activity, previously immunized mice were infected with TBEV strain Dal'negorsk (GenBank ID: FJ402886). The animal survival was monitored daily for 21 days. OmpF-EIII incorporated into the TI-complexes induced about a 30-60- and 5-10-fold increase in the production of anti-OmpF-EIII and anti-EIII antibodies, respectively, in comparison with the effect of an individual OmpF-EIII. The most effective vaccine construction provided 60% protection. Despite the dramatic effect on the specific antibody titer, the studied TI-complex did not provide a statistically significant increase in the protection of OmpF-EIII protein. However, our results provide the basis of the future search for approaches to design and optimize the anti-TBEV vaccine based on the OmpF-EIII protein. PMID- 30274358 TI - Optimization of Ultrasound-Assisted Extraction of Flavonoids from Olive (Olea europaea) Leaves, and Evaluation of Their Antioxidant and Anticancer Activities. AB - Olea europaea leaves are the major byproduct of olive farming. In this study, ultrasound-assisted extraction of flavonoids from olive leaves was optimized using response surface methodology, and the flavonoid compounds and their antioxidant and anticancer activities were investigated by high performance liquid chromatography. The results showed that the optimized conditions for achieving the maximum yield of flavonoids (74.95 mg RE/g dm) were 50 degrees C temperature, 270 W power, 50 min time, and 41 mL/g liquid-solid ratio. There was a significant difference in the total flavonoid content between the aged and young leaves harvested in April and July, and six main components were quantified. Among them, luteolin-4'-O-glucoside was the most predominant flavonoid compound, followed by apigenin-7-O-glucoside and rutin. Olive leaves also contained small amounts of luteolin, apigenin, and quercetin. Additionally, excellent antioxidant activity was exhibited when tested with the DPPH assay; superoxide radical-scavenging ability and reducing power was also tested. The anticancer activity of the flavonoids was assessed using HeLa cervical cancer cells, and it was observed that increasing concentrations of olive leaf flavonoids resulted in decreased cancer cell viability. These results suggest that the flavonoids from olive leaves could be used as a potential source of natural antioxidants for the pharmaceutical and food industries. PMID- 30274359 TI - Supplementation of Short-Chain Fatty Acid, Sodium Propionate, in Patients on Maintenance Hemodialysis: Beneficial Effects on Inflammatory Parameters and Gut Derived Uremic Toxins, A Pilot Study (PLAN Study) AB - BACKGROUND: In end-stage renal disease (ESRD), gut-derived uremic toxins play a crucial role in the systemic inflammation and oxidative stress promoting the excess morbidity and mortality. The biochemical derangement is in part a consequence of an insufficient generation of short-chain fatty acids (SCFA) due to the dysbiosis of the gut and an insufficient consumption of the fermentable complex carbohydrates. AIM OF THE STUDY: The primary end-point was to evaluate the potential efficacy of SCFA (specifically, sodium propionate (SP)) for patients on maintenance hemodialysis (MHD) on systemic inflammation. Secondary end-points included potential attenuation of oxidative stress markers, insulin resistance and production of gut-derived uremic toxins indoxyl sulfate and p cresol sulfate, as well as health status after SP supplementation. STUDY DESIGN: We performed a single-center non-randomized pilot study in 20 MHD patients. They received the food additive SP with a daily intake of 2 * 500 mg in the form of capsules for 12 weeks. Pre-dialysis blood samples were taken at the beginning, after six weeks and at the end of the administration period, as well as four weeks after withdrawal of the treatment. RESULTS: The subjects revealed a significant decline of inflammatory parameters C-reactive protein (-46%), interleukin IL-2 (-27%) and IL-17 (-15%). The inflammatory parameters IL-6 and IFN-gamma showed a mild non-significant reduction and the anti-inflammatory cytokine IL-10 increased significantly (+71%). While the concentration of bacterial endotoxins and TNF-alpha remained unchanged, the gut-derived uremic toxins, indoxyl sulfate (-30%) and p-cresyl sulfate (-50%), revealed a significant decline. The SP supplementation reduced the parameters of oxidative stress malondialdehyde (-32%) and glutathione peroxidase activity (-28%). The serum insulin levels dropped by 30% and the HOMA-index by 32%. The reduction of inflammatory parameters was associated with a lowering of ferritin and a significant increase in transferrin saturation (TSAT). Four weeks after the end of the treatment phase, all improved parameters deteriorated again. Evaluation of the psycho-physical performance with the short form 36 (SF-36) questionnaire showed an enhancement in the self-reported physical functioning, general health, vitality and mental health. The SP supplementation was well tolerated and without important side effects. No patient had left the study due to intolerance to the medication. The SP supplementation in MHD patients reduced pro-inflammatory parameters and oxidative stress and improved insulin resistance and iron metabolism. Furthermore, SP effectively lowered the important gut-derived uremic toxins indoxyl and p-cresol sulfate. These improvements were associated with a better quality of life. Further controlled studies are required in a larger cohort to evaluate the clinical outcome. PMID- 30274360 TI - Analysis of "2.28" KEEPER Chemical Industries Hazardous Chemical Explosion Accident Based on FTA and HFACS. AB - On 28 February 2012, a guanidine nitrate explosion occurred at HEBEI KEEPER Chemical Industries Co., Ltd., China, resulting in 25 deaths, with 4 missing individuals and 46 injured. In order to explore the causal relationship hidden behind this accident, fault tree analysis (FTA) and the Human Factors Analysis and Classification System (HFACS) were used to systematically analyze the incident. Firstly, FTA was used to analyze the causes of the accident in depth, until all the basic causal events causing the guanidine nitrate explosion were identified, and a fault tree diagram of the guanidine nitrate explosion was drawn. Secondly, for the unsafe acts in the basic causal events, the HFACS model was used to analyze the three levels of factors that lead to unsafe acts, including the preconditions for unsafe acts, unsafe supervision, and organizational influences. Finally, based on the analysis results of FTA and HFACS, a complete logic diagram of the causes of the accident was obtained. The FTA and HFACS accident analysis methods allowed for the identification of human factors and the accident evolution process in the explosion accident and provide a reference for accident investigation. PMID- 30274361 TI - Identification of a cis-Acting Element Derived from Tomato Leaf Curl Yunnan Virus that Mediates the Replication of a Deficient Yeast Plasmid in Saccharomyces cerevisiae. AB - Geminiviruses are a group of small single-stranded DNA viruses that replicate in the host cell nucleus. It has been reported that the viral replication initiator protein (Rep) and the conserved common region (CR) are required for rolling circle replication (RCR)-dependent geminivirus replication, but the detailed mechanisms of geminivirus replication are still obscure owing to a lack of a eukaryotic model system. In this study, we constructed a bacterial-yeast shuttle plasmid with the autonomous replication sequence (ARS) deleted, which failed to replicate in Saccharomyces cerevisiae cells and could not survive in selective media either. Tandemly repeated copies of 10 geminivirus genomic DNAs were inserted into this deficient plasmid to test whether they were able to replace the ARS to execute genomic DNA replication in yeast cells. We found that yeast cells consisting of the recombinant plasmid with 1.9 tandemly repeated copies of tomato leaf curl Yunnan virus isolate Y194 (TLCYnV-Y194, hereafter referred to as Y194) can replicate well and survive in selective plates. Furthermore, we showed that the recombinant plasmid harboring the Y194 genome with the mutation of the viral Rep or CR was still able to replicate in yeast cells, indicating the existence of a non-canonic RCR model. By a series of mutations, we mapped a short fragment of 174 nucleotides (nts) between the V1 and C3 open reading frames (ORFs), including an ARS-like element that can substitute the function of the ARS responsible for stable replication of extrachromosomal DNAs in yeast. The results of this study established a geminivirus replication system in yeast cells and revealed that Y194 consisting of an ARS-like element was able to support the replication a bacterial-yeast shuttle plasmid in yeast cells. PMID- 30274362 TI - Integrating Early Growth Information to Monitor Winter Wheat Powdery Mildew Using Multi-Temporal Landsat-8 Imagery. AB - Powdery mildew is one of the dominant diseases in winter wheat. The accurate monitoring of powdery mildew is important for crop management and production. Satellite-based remote sensing monitoring has been proven as an efficient tool for regional disease detection and monitoring. However, the information provided by single-date satellite scene is hard to achieve acceptable accuracy for powdery mildew disease, and incorporation of early period contextual information of winter wheat can improve this situation. In this study, a multi-temporal satellite data based powdery mildew detecting approach had been developed for regional disease mapping. Firstly, the Lansat-8 scenes that covered six winter wheat growth periods (expressed in chronological order as periods 1 to 6) were collected to calculate typical vegetation indices (VIs), which include disease water stress index (DSWI), optimized soil adjusted vegetation index (OSAVI), shortwave infrared water stress index (SIWSI), and triangular vegetation index (TVI). A multi-temporal VIs-based k-nearest neighbors (KNN) approach was then developed to produce the regional disease distribution. Meanwhile, a backward stepwise elimination method was used to confirm the optimal multi-temporal combination for KNN monitoring model. A classification and regression tree (CART) and back propagation neural networks (BPNN) approaches were used for comparison and validation of initial results. VIs of all periods except 1 and 3 provided the best multi-temporal data set for winter wheat powdery mildew monitoring. Compared with the traditional single-date (period 6) image, the multi-temporal images based KNN approach provided more disease information during the disease development, and had an accuracy of 84.6%. Meanwhile, the accuracy of the proposed approach had 11.5% and 3.8% higher than the multi-temporal images-based CART and BPNN models', respectively. These results suggest that the use of satellite images for early critical disease infection periods is essential for improving the accuracy of monitoring models. Additionally, satellite imagery also assists in monitoring powdery mildew in late wheat growth periods. PMID- 30274363 TI - Dominant Role of Young's Modulus for Electric Power Generation in PVDF-BaTiO3 Composite-Based Piezoelectric Nanogenerator. AB - The electric power output of a piezoelectric nanogenerator (PENG) depends on the various physical parameters of the constituent materials, including the piezoelectric coefficient, Young's modulus, and dielectric constant. Herein, we report the mechanical and electrical properties of a poly(vinylidene fluoride) BaTiO3 (PVDF-BTO) composite-based PENG. Variation of the BTO nanoparticle (NP) content enabled the systematic tuning of the physical parameters that are related to power generation in the composite. The Young's modulus of the PVDF-BTO composite initially increased, and then eventually decreased, with the increasing BTO content, which was probably due to the clustering effect of the high modulus BTO NPs. The dielectric constant of the composite continuously increased as the BaTiO3 content increased. The piezoelectric outputs were greatly enhanced at 10 wt% of BTO, where the Young's modulus was the highest. These results indicate that the Young's modulus plays an important role in the piezoelectric power generation of the composite-based PENGs. PMID- 30274364 TI - Potential Role of Microfibrillar-Associated Protein 4, Fibrotic Indices and Oxidative Stress in Hepatocellular Carcinoma. AB - Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related mortality worldwide. In an attempt to understand some potential mechanisms of persistence and oncogenicity of Hepatitis C virus (HCV)-related HCC, microfibrillar-associated protein 4 (MFAP4), fibrotic indices and oxidative status biomarkers were assessed in the sera of 50 patients with HCV-associated HCC, 25 patients with HCV-related liver cirrhosis and 15 healthy individuals. Serum oxidized Coenzyme Q10 (CoQ10) and malondialdehyde showed significant elevation in HCC patients compared to the control group (p < 0.001), as well as cirrhotic patients (p < 0.05 and p < 0.001, respectively), while serum glutathione content and superoxide dismutase activity were significantly decreased in HCC patients compared to the control group (p < 0.001). Serum MFAP4, aspartate aminotransferase to platelet ratio index (APRI), fibrosis index based on the 4 factors (FIB-4) and Forns index showed significant increase in HCC patients compared to the control group (p < 0.001), while only APRI and FIB-4 were significantly different between HCC and cirrhotic patients (p < 0.05), with a sensitivity of 86% and 92%, respectively, at cut off >=0.7 for APRI and >=1.57 for FIB-4. Therefore, increasing oxidative stress and fibrosis might mediate HCV induced cirrhosis and HCC. APRI and FIB-4 may be used as a simple non-expensive formula for the screening of HCC rather than MFAP4. PMID- 30274366 TI - Directed Evolution of a Homodimeric Laccase from Cerrena unicolor BBP6 by Random Mutagenesis and In Vivo Assembly. AB - Laccases have great potential for industrial applications due to their green catalytic properties and broad substrate specificities, and various studies have attempted to improve the catalytic performance of these enzymes. Here, to the best of our knowledge, we firstly report the directed evolution of a homodimeric laccase from Cerrena unicolor BBP6 fused with alpha-factor prepro-leader that was engineered through random mutagenesis followed by in vivo assembly in Saccharomyces cerevisiae. Three evolved fusion variants selected from ~3500 clones presented 31- to 37-fold increases in total laccase activity, with better thermostability and broader pH profiles. The evolved alpha-factor prepro-leader enhanced laccase expression levels by up to 2.4-fold. Protein model analysis of these variants reveals that the beneficial mutations have influences on protein pKa shift, subunit interaction, substrate entrance, and C-terminal function. PMID- 30274365 TI - Short Telomere Length as a Biomarker Risk of Lung Cancer Development Induced by High Radon Levels: A Pilot Study. AB - Long-term exposure to radon has been determined to be the second leading cause of lung cancer after tobacco smoking. However, an in-depth study of this topic has not been explicitly carried out in Chiang Mai (Thailand). This paper presents the results of an indoor radon level measurement campaign in dwellings of Chiang Mai using total of 110 detectors (CR-39) during one year. The results show that the average radon levels varied from 35 to 219 Bq/m3, with an overall average of 57 Bq/m3. The finding also shows that the average value is higher than the global average value of 39 Bq/m3. In addition, to examine the cause of lung cancer development among people with risk of chronic exposure to radon during their lifetime, 35 non-smoker lung cancer patients and 33 healthy nonsmokers were analyzed for telomere length. As expected, telomere length was significantly shorter in lung cancer patients than in healthy nonsmokers. Among healthy nonsmokers, the telomere length was significantly shorter in a high radon group than in an unaffected low radon group. To the best of our knowledge, our research provides the first attempt in describing the shortened telomeres in areas with high levels of environmental radon that might be related to lung cancer development. PMID- 30274367 TI - Quasicontinuum Simulation of the Effect of Lotus-Type Nanocavity on the Onset Plasticity of Single Crystal Al during Nanoindentation. AB - Stress concentration around nanosized defects such as cavities always leads to plastic deformation and failure of solids. We investigate the effects of depth, size, and shape of a lotus-type nanocavity on onset plasticity of single crystal Al during nanoindentation on a (001) surface using a quasicontinuum method. The results show that the presence of a nanocavity can greatly affect the contact stiffness (Sc) and yield stress (sigmay) of the matrix during nanoindentation. For a circular cavity, the Sc and sigmay gradually increase with the cavity depth. A critical depth can be identified, over which the Sc and sigmay are insensitive to the cavity depth and it is firstly observed that the nucleated dislocations extend into the matrix and form a y-shaped structure. Moreover, the critical depth varies approximately linearly with the indenter size, regarding the same cavity. The Sc almost linearly decreases with the cavity diameter, while the sigmay is slightly affected. For an ellipsoidal cavity, the Sc and sigmay increase with the aspect ratio (AR), while they are less affected when the AR is over 1. Our results shed light in the mechanical behavior of metals with cavities and could also be helpful in designing porous materials and structures. PMID- 30274369 TI - A Framework for Development of Useful Metabolomic Biomarkers and Their Effective Knowledge Translation. AB - Despite the significant advantages of metabolomic biomarkers, no diagnostic tests based on metabolomics have been introduced to clinical use. There are many reasons for this, centered around substantial obstacles in developing clinically useful metabolomic biomarkers. Most significant is the need for interdisciplinary teams with expertise in metabolomics, analysis of complex clinical and metabolomic data, and clinical care. Importantly, the clinical need must precede biomarker discovery, and the experimental design for discovery and validation must reflect the purpose of the biomarker. Standard operating procedures for procuring and handling samples must be developed from the beginning, to ensure experimental integrity. Assay design is another challenge, as there is not much precedent informing this. Another obstacle is that it is not yet clear how to protect any intellectual property related to metabolomic biomarkers. Viewing a metabolomic biomarker as a natural phenomenon would inhibit patent protection and potentially stifle commercial interest. However, demonstrating that a metabolomic biomarker is actually a derivative of a natural phenomenon that requires innovation would enhance investment in this field. Finally, effective knowledge translation strategies must be implemented, which will require engagement with end users (clinicians and lab physicians), patient advocate groups, policy makers, and payer organizations. Addressing each of these issues comprises the framework for introducing a metabolomic biomarker to practice. PMID- 30274368 TI - Children's Blood Lead Concentrations from 1988 to 2015 in Mexico City: The Contribution of Lead in Air and Traditional Lead-Glazed Ceramics. AB - Despite the removal of lead from gasoline in 1997, elevated blood lead levels (BLLs) > 5 ug/dL are still detectable in children living in Mexico City. The use of lead-glazed ceramics may explain these persistent exposure levels. Mexico lacks a national surveillance program for BLL, but temporal trends can be derived from epidemiological studies. With this approach, we leveraged a series of birth cohorts to report BLL trends from 1987 to 2002 and expanded our analysis to 2015. Data were from 1-5-year-old children from five Mexico City cohorts followed between 1988 and 2015. BLLs are reported on 1963 children, who contributed 4975 BLLs. We estimated the trend of mean BLL, which decreased from 15.7 ug/dL in 1988, to 7.8 ug/dL in 1998 (a year after the total ban of lead in gasoline), to 1.96 ug/dL in 2015. The proportion of BLL >= 5 ug/dL decreased from 92% (1988 1998) to 8% (2008-2015). The use of lead-glazed ceramics was associated with an 11% increase in BLLs throughout the study period. Replacing lead-based glazes in traditional ceramics may be the key to further reducing exposure, but this presents challenges, as it involves a cultural tradition deeply rooted in Mexico. In addition, the creation of a rigorous, standardized, and on-going surveillance program of BLL is necessary for identifying vulnerable populations. PMID- 30274370 TI - SWIPT-Aware Fog Information Processing: Local Computing vs. Fog Offloading. AB - This paper studies a simultaneous wireless information and power transfer (SWIPT) aware fog computing by using a simple model, where a sensor harvests energy and receives information from a hybrid access point (HAP) through power splitting (PS) receiver architecture. Two information processing modes, local computing and fog offloading modes are investigated. For such a system, two optimization problems are formulated to minimize the sensor's required power for the two modes under the information rate and energy harvesting constraints by jointly optimizing the time assignment and the transmit power, as well as the PS ratio. The closed-form and semi-closed-form solutions to the proposed optimization problems are derived based on convex optimization theory. Simulation results show that neither mode is always superior to the other one. It also shows that when the number of logic operations per bit associated with local computing is less than a certain value, the local computing mode is a better choice; otherwise, the fog offloading mode should be selected. In addition, the mode selection associated with the positions of the user for fixed HAP and fog server (FS) is also discussed. PMID- 30274372 TI - UPLC-MS/MS Method for the Determination of 14 Compounds in Rat Plasma and Its Application in a Pharmacokinetic Study of Orally Administered Xiaoyao Powder. AB - Xiaoyao Powder (XYP), a common Chinese medicine, comprises eight traditional Chinese herbs and has been widely used clinically to treat liver damage and mental disorders. An ultra-performance liquid chromatography-tandem mass spectrometry method was developed to investigate the pharmacokinetics of 14 compounds (albiflorin, paeoniflorin, ferulic acid, senkyunolide I, quercetin, isoliquiritigenin, atractylenolide III, ligustilide, atractylenolide II, liquiritin, liquiritigenin, saikosaponin c, glycyrrhizic acid, and saikosaponin a) in XYP. Naringenin was used as the internal standard. The compounds were separated using an ACQUITY UPLCTM BEH C18 column (1.7 MUm, 50 * 2.1 mm) with a mobile phase consisting of acetonitrile and 0.1% formic acid in water at a flow rate of 0.3 mL/min. Detection was performed on a triple-quadrupole tandem mass spectrometer using multiple reaction monitoring and an electrospray ionization source in both positive and negative ionization modes. All calibration curves exhibited good linearity (r2 > 0.9974) over the measured ranges. The intra- and inter-day precisions were within 12%, and the accuracy ranged from 89.93% to 106.64%. Extraction recovery and matrix effect results were satisfactory. The method was successfully applied in a pharmacokinetic study of the 14 compounds in rat plasma after the oral administration of XYP. PMID- 30274371 TI - OPNa Overexpression Is Associated with Matrix Calcification in Thyroid Cancer Cell Lines. AB - Osteopontin (OPN) spliced variants (OPN-SV: OPNa, OPNb, and OPNc) are aberrantly expressed in tumors and frequently associated with cancer progression. This holds true for papillary thyroid carcinoma (PTC), which is the most common type of thyroid cancer (TC). PTC often presents with desmoplasia and dystrophic calcification, including psammoma bodies (PB). This work aimed to investigate total OPN (tOPN) and OPN-SV expression and their association with the presence of PB in the PTC classical variants (cPTC), as well as the involvement of OPN-SV in matrix calcification of TC cell lines. We found that cPTC samples presenting PB showed higher OPN expression levels. In TC cell lines, OPNa overexpression promotes higher matrix calcification and collagen synthesis when compared to that of clones overexpressing OPNb or OPNc. In response to OPN knockdown, calcification was inhibited, paralleled with the downregulation of calcification markers. In conclusion, our data evidenced that OPN expression is associated with the presence of PB in cPTC samples. Among the OPN-SV, OPNa is the main contributor to matrix calcification in tested TC cells, providing clues to a better understanding on the biology and ethiopathogenesis of the calcification process in TC cells.

AB - This paper investigates the joint impact of channel estimation errors (CEEs) and hardware impairments (HIs) on the performance of a cognitive satellite terrestrial relay network (CSTRN), where the terrestrial and satellite links are considered following Rayleigh fading and shadowed Rician (SR) fading distributions, respectively. Besides, the terrestrial relay is working in half duplex decode-and-forward (DF) mode. By employing a general and practical model to account for both the CEEs and HIs at each link, the end-to-end signal-to-noise plus-distortion-and-error ratio (SNDER) is first obtained for the CSTRN. Then, closed-form expressions for the outage probability (OP) and throughput of the CSTRN are obtained, which allows us to demonstrate the aggregate impact of CEEs and HIs. In order to gain insightful findings, we further elaborate on the asymptotic OP and throughput at the high signal-to-noise-ratio (SNR) condition and quantitatively determine the fundamental performance ceiling. Finally, Monte Carlo (MC) computer simulations are provided to verify the correctness of the analytical results. Besides, with representative numerical analysis's help, interesting findings are presented.

AB - Arterial Blood Pressure (ABP) and photoplethysmography (PPG) are both useful techniques to monitor cardiovascular status. Though ABP monitoring is more widely employed, this procedure of signal acquisition whether done invasively or non invasively may cause inconvenience and discomfort to the patients. PPG, however, is simple, noninvasive, and can be used for continuous measurement. This paper focuses on analyzing the similarities in time and frequency domains between ABP and PPG signals for normotensive, prehypertensive and hypertensive subjects and the feasibility of the classification of subjects considering the results of the analysis performed. From a database with 120 records of ABP and PPG, each 120 s in length, the records where separated into epochs taking into account 10 heartbeats, and the following statistical measures were performed: Correlation (r), Coherence (COH), Partial Coherence (pCOH), Partial Directed Coherence (PDC), Directed Transfer Function (DTF), Full Frequency Directed Transfer Function (ffDTF) and Direct Directed Transfer Function (dDTF). The correlation coefficient was r > 0.9 on average for all groups, indicating a strong morphology similarity. For COH and pCOH, coherence (linear correlation in frequency domain) was found with significance (p < 0.01) in differentiating between normotensive and hypertensive subjects using PPG signals. For the dataset at hand, only two synchrony measures are able to convincingly distinguish hypertensive subjects from normotensive control subjects, i.e., ffDTF and dDTF. From PDC, DTF, ffDTF, and dDTF, a consistent, a strong significant causality from ABP->PPG was found. When all synchrony measures were combined, an 87.5 % accuracy was achieved to detect hypertension using a Neural Network classifier, suggesting that PPG holds most informative features that exist in ABP.

AB - AMP-activated protein kinase (AMPK) is a heterotrimeric serine/threonine kinase consisting of the arrangement of various alpha? beta, and gamma?isoforms that are expressed differently depending on the tissue or the cell lineage. AMPK is one of the major sensors of energy status in mammalian cells and as such plays essential roles in the regulation of cellular homeostasis, metabolism, cell growth, differentiation, apoptosis, and autophagy. AMPK is activated by two upstream kinases, the tumor suppressor liver kinase B1 (LKB1) and the calcium/calmodulin dependent protein kinase kinase 2 (CAMKK2) through phosphorylation of the kinase on Thr172, leading to its activation. In addition, AMPK inhibits the mTOR pathway through phosphorylation and activation of tuberous sclerosis protein 2 (TSC2) and causes direct activation of unc-51-like autophagy activating kinase 1 (ULK1) via phosphorylation of Ser555, thus promoting initiation of autophagy. Although it is well established that AMPK can control the differentiation of different cell lineages, including hematopoietic stem cells (HSCs), progenitors, and mature hematopoietic cells, the role of AMPK regarding myeloid cell differentiation is less documented. The differentiation of monocytes into macrophages triggered by colony stimulating factor 1 (CSF-1), a process during which both caspase activation (independently of apoptosis induction) and AMPK-dependent stimulation of autophagy are necessary, is one noticeable example of the involvement of AMPK in the physiological differentiation of myeloid cells. The present review focuses on the role of AMPK in the regulation of the physiological and pathological differentiation of myeloid cells. The mechanisms of autophagy induction by AMPK will also be addressed, as autophagy has been shown to be important for differentiation of hematopoietic cells. In addition, myeloid malignancies (myeloid leukemia or dysplasia) are characterized by profound defects in the establishment of proper differentiation programs. Reinduction of a normal differentiation process in myeloid malignancies has thus emerged as a valuable and promising therapeutic strategy. As AMPK seems to exert a key role in the differentiation of myeloid cells, notably through induction of autophagy, we will also discuss the potential to target this pathway as a pro-differentiating and anti-leukemic strategy in myeloid malignancies.

AB - Kaolinite can be used as in-furnace adsorbent to capture gaseous semi-volatile metals during combustion, incineration, or gasification processes for the purposes of toxic metals emission control, ash deposition/slagging/corrosion inhibition, ultrafine particulate matter emission control, and so on. In this work, the adsorptions of typical heavy metals (Pb and Cd) and typical alkali metals (Na and K) by meta-kaolinite were investigated by the DFT calculation. The adsorption energies followed the sequence of NaOH-Si surface > KOH-Si surface > PbO-Al surface ~ CdO-Al surface ~ NaOH-Al surface > KOH-Al surface > NaCl-Al surface ~ Na-Si surface > Na-Al surface > KCl-Al surface > Pb-Al surface > PbCl2 Al surface > CdCl2-Al surface ~ K-Si surface ~ PbCl-Al surface > K-Al surface > CdCl-Al surface > NaCl-Si surface > KCl-Si surface > Cd-Al surface. Si surface was found available to the adsorptions of Na, K, and their compounds, although it was invalid to the adsorptions of Pb, Cd, and their compounds. The interactions between adsorbates and surfaces were revealed. Furthermore, the discussion of combining with the experimental data was applied to the subject validity of calculation results and the effect of chlorine on adsorption and the effect of reducing atmosphere on adsorption. PMID- 30274375 TI - Alcohol and the Developing Brain: Why Neurons Die and How Survivors Change. AB - The consequences of alcohol drinking during pregnancy are dramatic and usually referred to as fetal alcohol spectrum disorders (FASD). This condition is one of the main causes of intellectual disability in Western countries. The immature fetal brain exposed to ethanol undergoes massive neuron death. However, the same mechanisms leading to cell death can also be responsible for changes of developmental plasticity. As a consequence of such a maladaptive plasticity, the functional damage to central nervous system structures is amplified and leads to permanent sequelae. Here we review the literature dealing with experimental FASD, focusing on the alterations of the cerebral cortex. We propose that the reciprocal interaction between cell death and maladaptive plasticity represents the main pathogenetic mechanism of the alcohol-induced damage to the developing brain. PMID- 30274378 TI - Inhibition of Experimental Choroidal Neovascularization by a Novel Peptide Derived from Calreticulin Anti-Angiogenic Domain. AB - Choroidal neovascularization (CNV) is a key pathological feature of several leading causes of vision loss including neovascular age-related macular degeneration. Here, we show that a calreticulin anti-angiogenic domain (CAD)-like peptide 27, CAD27, inhibited in vitro angiogenic activities, including tube formation, migration of endothelial cells, and vascular sprouting from rat aortic ring explants. In a rat model of laser-induced CNV, we demonstrate that intravitreal injection of CAD27 significantly attenuated the formation of CNV lesions as measured via fundus fluorescein angiography and choroid flat-mounts (19.5% and 22.4% reductions at 10 MUg and 20 MUg of CAD27 injected, respectively). Similarly, the reduction of CNV lesions was observed in rats that had received topical applications of CAD27 (choroid flat-mounts: 17.9% and 32.5% reductions at 10 MUg/mL and 20 MUg/mL of CAD27 instilled, respectively). Retinal function was unaffected, as measured using electroretinography in both groups receiving interareal injection or topical applications of CAD27 for at least fourteen days. These findings show that CAD27 can be used as a potential therapeutic alternative for targeting CNV in diseases such as neovascular age related macular degeneration. PMID- 30274379 TI - Effect of Hybrid Carbon Fillers on the Electrical and Morphological Properties of Polystyrene Nanocomposites in Microinjection Molding. AB - The effect of hybrid carbon fillers of multi-walled carbon nanotubes (CNT) and carbon black (CB) on the electrical and morphological properties of polystyrene (PS) nanocomposites were systematically investigated in microinjection molding (MUIM). The polymer nanocomposites with three different filler concentrations (i.e., 3, 5 and 10 wt %) at various weight ratios of CNT/CB (100/0, 30/70, 50/50, 70/30, 0/100) were prepared by melt blending, then followed by MUIM under a defined set of processing conditions. A rectangular mold insert which has three consecutive zones with decreasing thickness along the flow direction was adopted to study abrupt changes in mold geometry on the properties of resultant microparts. The distribution of carbon fillers within microparts was observed by scanning electron microscopy, which was correlated with electrical conductivity measurements. Results indicated that there is a flow-induced orientation of incorporated carbon fillers and this orientation increased with increasing shearing effect along the flow direction. High structure CB is found to be more effective than CNT in terms of enhancing the electrical conductivity, which was attributed to the good dispersion of CB in PS and their ability to form conductive networks via self-assembly. Morphology observations indicated that there is a shear-induced depletion of CB particles in the shear layer, which is due to the marked difference of shear rates between the shear and core layers of the molded microparts. Moreover, an annealing treatment is beneficial to enhance the electrical conductivity of CNT-containing microparts. PMID- 30274380 TI - Design, Synthesis, and Cytotoxic Analysis of Novel Hederagenin-Pyrazine Derivatives Based on Partial Least Squares Discriminant Analysis. AB - Hederagenin (He) is a novel triterpene template for the development of new antitumor compounds. In this study, 26 new He-pyrazine derivatives were synthetized in an attempt to develop potent antitumor agents; they were screened for in vitro cytotoxicity against tumor and non-tumor cell lines. The majority of these derivatives showed much stronger cytotoxic activity than He. Remarkably, the most potent was compound 9 (half maximal inhibitory concentration (IC50) was 3.45 +/- 0.59 MUM), which exhibited similar antitumor activities against A549 (human non-small-cell lung cancer) as the positive drug cisplatin (DDP; IC50 was 3.85 +/- 0.63 MUM), while it showed lower cytotoxicity on H9c2 (murine heart myoblast; IC50 was 16.69 +/- 0.12 MUM) cell lines. Compound 9 could induce the early apoptosis and evoke cell-cycle arrest at the synthesis (S) phase of A549 cells. Impressively, we innovatively introduced the method of cluster analysis modeled as partial least squares discriminant analysis (PLS-DA) into the structure-activity relationship (SAR) evaluation, and SAR confirmed that pyrazine had a profound effect on the antitumor activity of He. The present studies highlight the importance of pyrazine derivatives of He in the discovery and development of novel antitumor agents.

AB - While arterial reflow after a stroke represents an important challenge for better outcomes, it is also very important that sudden recanalization does not produce local oxidative and nitrogen species, deleterious for the brain and more particularly the immature brain. Our objective was to determine whether a supply in prostaglandin (Pg) E1 (Alprostadil), via its action on arterial pressure, might progressively improve cerebral reperfusion in a neonatal stroke model. Arterial blood flow was measured using ultrasonography. Rate-limiting and Pg terminal synthesizing enzymes were evaluated using reverse-transcriptase polymerase chain reaction. Our data suggests that a supply in PgE1 might delay and improve the ipsilateral reperfusion by decreasing thromboxane A synthase-1 gene, the density of reactive astrocytes and lesion volume. PMID- 30274382 TI - Robust Beamforming Design for Secure V2X Downlink System with Wireless Information and Power Transfer under a Nonlinear Energy Harvesting Model. AB - Vehicle to everything (V2X) has been deemed a promising technology due to its potential to achieve traffic safety and efficiency. This paper considers a V2X downlink system with a simultaneous wireless information and power transfer (SWIPT) system where the base station not only conveys data and energy to two types of wireless vehicular receivers, such as one hybrid power-splitting vehicular receiver, and multiple energy vehicular receivers, but also prevents information from being intercepted by the potential eavesdroppers (idle energy vehicular receivers). Both the base station and the energy vehicular receivers are equipped with multiple antennas, whereas the information vehicular receiver is equipped with a single antenna. In particular, the imperfect channel state information (CSI) and the practical nonlinear energy harvesting (EH) model are taken into account. The non-convex optimization problem is formulated to maximize the minimum harvested energy power among the energy vehicular receivers satisfying the lowest harvested energy power threshold at the information vehicular receiver and secure vehicular communication requirements. In light of the intractability of the optimization problem, the semidefinite relaxation (SDR) technique and variable substitutions are applied, and the optimal solution is proven to be tight. A number of results demonstrate that the proposed robust secure beamforming scheme has better performance than other schemes. PMID- 30274383 TI - Adaptive Ship Detection for Single-Look Complex SAR Images Based on SVWIE Noncircularity Decomposition. AB - In this paper, we present an adaptive ship detection method for single-look complex synthetic aperture radar (SAR) images. First, noncircularity is analyzed and adopted in ship detection task; besides, similarity variance weighted information entropy (SVWIE) is proposed for clutter reduction and target enhancement. According to the analysis of scattering of SVWIE and noncircularity, SVWIE-noncircularity (SN) decomposition is developed. Based on the decomposition, two components, the high-noncircularity SVWIE amplitude (h) and the low noncircularity SVWIE amplitude (l), are obtained. We demonstrate that ships and clutter in SAR images are different for h detector and h detector can be effectively used for ship detection. Finally, to extract ships from the background, the generalized Gamma distribution (G Gamma D) is used to fit h statistics of clutter and the constant false alarm rate (CFAR) is utilized to choose an adaptive threshold. The performance of the proposed method is demonstrated on HH polarization of Alos-2 images. Experimental results show that the proposed method can accurately detect ships in complex background, i.e., ships are close to small islands or with strong noise. PMID- 30274385 TI - Sorbitol as a Chain Extender of Polyurethane Prepolymers to Prepare Self-Healable and Robust Polyhydroxyurethane Elastomers. AB - A self-healable polyhydroxyurethane (S-PU) was synthesized from sorbitol, a biomass of polyhydric alcohol, by a simple process that is suitable for practical applications. In the synthesis, only two primary hydroxyl groups of sorbitol were considered for the chain extension of the polyurethane (PU) prepolymers to introduce free hydroxyl groups in PU. As a control, conventional PU was synthesized by hexane diol mediated chain extension. Relative to the control, S PU showed excellent intrinsic self-healing property via exchange reaction, which was facilitated by the nucleophilic addition of the secondary hydroxyl groups without any catalytic assistance and improved tensile strength due to the enhanced hydrogen bonding. We also investigated the effect of the exchange reaction on the topological, mechanical, and rheological properties of S-PU. The suggested synthetic framework for S-PU is a promising alternative to the conventional poly hydroxyurethane, in which cyclic carbonates are frequently reacted with amines. As such, it is a facile and environmentally friendly material for use in coatings, adhesives, and elastomers.

AB - There is well-documented evidence that shows phytoremediation and restoration methods affect physical and chemical properties, enzyme activities, and microbial communities of soil. In this study, we investigated the response of soil microbial communities to restoration time. We found that arsenic content decreased gradually as restoration progressed. Total carbon (C) in shoots and total nitrogen (N) in roots of B. ischaemum both exhibited increasing trends with an increase in restoration time. The transfer factor of chromium was negatively correlated to C in shoots and positively correlated to sulfur in roots. Additionally, the transfer factor of lead had a remarkably positive correlation to the C/N ratio of roots. For soil enzymes, total N in soil was positively correlated to catalase and urease but negatively correlated to sucrose. Moreover, bulk soil bacterial composition was positively correlated to catalase, sucrase and phosphatase while fungal diversity was positively correlated to sucrose. This study found that restoration time plays the most significant role in bacterial and fungal composition and bacterial diversity, but it has no effect on fungal diversity in rhizosphere and non-rhizosphere soil. In addition, the driving factors of microbial composition and diversity varied in rhizosphere and non rhizosphere soil among the different restoration time treatments. PMID- 30274386 TI - sEMG-Based Drawing Trace Reconstruction: A Novel Hybrid Algorithm Fusing Gene Expression Programming into Kalman Filter. AB - How to reconstruct drawing and handwriting traces from surface electromyography (sEMG) signals accurately has attracted a number of researchers recently. An effective algorithm is crucial to reliable reconstruction. Previously, nonlinear regression methods have been utilized successfully to some extent. In the quest to improve the accuracy of transient myoelectric signal decoding, a novel hybrid algorithm KF-GEP fusing Gene Expression Programming (GEP) into Kalman Filter (KF) framework is proposed for sEMG-based drawing trace reconstruction. In this work, the KF-GEP was applied to reconstruct fourteen drawn shapes and ten numeric characters from sEMG signals across five participants. Then the reconstruction performance of KF-GEP, KF and GEP were compared. The experimental results show that the KF-GEP algorithm performs best because it combines the advantages of KF and GEP. The findings add to the literature on the muscle-computer interface and can be introduced to many practical fields. PMID- 30274387 TI - Optical Micro/Nanofiber-Based Localized Surface Plasmon Resonance Biosensors: Fiber Diameter Dependence. AB - Integration of functional nanomaterials with optical micro/nanofibers (OMNFs) can bring about novel optical properties and provide a versatile platform for various sensing applications. OMNFs as the key element, however, have seldom been investigated. Here, we focus on the optimization of fiber diameter by taking micro/nanofiber-based localized surface plasmon resonance sensors as a model. We systematically study the dependence of fiber diameter on the sensing performance of such sensors. Both theoretical and experimental results show that, by reducing fiber diameter, the refractive index sensitivity can be significantly increased. Then, we demonstrate the biosensing capability of the optimized sensor for streptavidin detection and achieve a detection limit of 1 pg/mL. Furthermore, the proposed theoretical model is applicable to other nanomaterials and OMNF-based sensing schemes for performance optimization. PMID- 30274388 TI - Taurine and Methylprednisolone Administration at Close Proximity to the Onset of Muscle Degeneration Is Ineffective at Attenuating Force Loss in the Hind-Limb of 28 Days Mdx Mice. AB - An increasing number of studies have shown supplementation with the amino acid taurine to have promise in ameliorating dystrophic symptoms in the mdx mouse model of Duchenne Muscular Dystrophy (DMD). Here we build on this limited body of work by investigating the efficacy of supplementing mdx mice with taurine postnatally at a time suggestive of when dystrophic symptoms would begin to manifest in humans, and when treatments would likely begin. Mdx mice were given either taurine (mdx tau), the steroid alpha methylprednisolone (PDN), or tau + PDN (mdx tau + PDN). Taurine (2.5% wt/vol) enriched drinking water was given from 14 days and PDN (1 mg/kg daily) from 18 days. Wild-type (WT, C57BL10/ScSn) mice were used as a control to mdx mice to represent healthy tissue. In the mdx mouse, peak damage occurs at 28 days, and in situ assessment of contractile characteristics showed that taurine, PDN, and the combined taurine + PDN treatment was ineffective at attenuating the force loss experienced by mdx mice. Given the benefits of taurine as well as methylprednisolone reported previously, when supplemented at close proximity to the onset of severity muscle degeneration these benefits are no longer apparent. PMID- 30274389 TI - Structural and Magnetic Properties of Ni0.8Fe0.2/Ti Nanoscale Multilayers. AB - The influence of the thickness of the Ni0.8Fe0.2 (Permalloy, Py) layers on the structural and magnetic properties of magnetron sputtered Py/Ti multilayers was studied. The thickness of the Py layers was varied in the interval of 8 to 30 A. X-ray reflectivity scans evidence the existence of a well-defined layered structure in all the samples considered, but also the presence of a complex intermixed interface. The shape of both the temperature dependence of magnetization and the hysteresis loops of the multilayered structures depends strongly on Py thickness. Magnetic and reflectivity measurements were comparatively analyzed in order to better understand the structure of the samples, and specifically, their interfaces. In particular, the presence of small superparamagnetic Py at the interfaces of the samples, especially evident in the samples with the thinnest Py layers, seems confirmed by the magnetic measurements, agreeing well with the reflectivity results.

AB - Mixed chlorometallate ionic liquids (ILs) have been regarded as potential solvents, catalysts, and reagents for many organic processes. The acidity and basicity of these ILs were correlated with theoretically estimated parameters such as electrostatic surface potential maxima and minima, average local surface ionization energy, and Fukui and dual descriptor functions. The introduction of metal chloride into the anions would influence the acidity/basicity of ILs by withdrawing the electron density from the cationic counterpart. For the [C4mim] based ILs with the mixed-metal anions, the acidity tends to attenuate while the basicity becomes stronger, as compared to the corresponding chloroaluminate ILs. However, the acidity of [(C2H5)3NH]-based ILs with the mixed-metal anions are greater than that of the net chloroaluminate ILs. The Fukui function values showed that most of the mixed chlorometallate ILs belong to bifunctional distribution. The mixed chlorometallate ILs both have electrophilic and nucleophilic sites, which would be beneficial for their applications. PMID- 30274391 TI - Educational Attainment Better Protects African American Women than African American Men Against Depressive Symptoms and Psychological Distress. AB - BACKGROUND: Recent research has shown smaller health effects of socioeconomic status (SES) indicators such as education attainment for African Americans as compared to whites. However, less is known about diminished returns based on gender within African Americans. AIM: To test whether among African American men are at a relative disadvantage compared to women in terms of having improved mental health as a result of their education attainment. This study thus explored gender differences in the association between education attainment and mental health, using a representative sample of American adults. METHODS: The National Survey of American Life (NSAL; 2003) recruited 3570 African American adults (2299 females and 1271 males). The dependent variables were depressive symptoms and psychological distress. The independent variable was education attainment. Race was the focal moderator. Age, employment status, and marital status were covariates. Linear regressions were used for data analysis. RESULTS: In the pooled sample that included both male and female African American adults, high education attainment was associated with lower depressive symptoms and psychological distress, net of covariates. Significant interactions were found between gender and education attainment with effects on depressive symptoms and psychological distress, suggesting stronger protective effects of high education attainment against depressive symptoms and psychological distress for female as compared to male African Americans. CONCLUSION: A smaller gain in mental health with respect to educational attainment for male African American males as compared to African American females is in line with studies showing high risk of depression in African American men of high-socioeconomic status. High-SES African American men need screening for depression and psychological distress. PMID- 30274392 TI - Modification Effects of B2O3 on The Structure and Catalytic Activity of WO3-UiO 66 Catalyst. AB - Tungsten oxide (WO3) and boron oxide (B2O3) were irreversibly encapsulated into the nanocages of the Zr-based metal organic framework UiO-66, affording a hybrid material B2O3-WO3/UiO-66 by a simple microwave-assisted deposition method. The novel B2O3-WO3/UiO-66 material was systematically characterized by X-ray diffraction, Fourier transform infrared spectroscopy, N2 adsorption, ultraviolet visible diffuse reflectance spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray phosphorescence, and Fourier transform infrared (FTIR)-CO adsorption methods. It was found that WO3 and B2O3 were highly dispersed in the nanocages of UiO-66, and the morphology and crystal structure of UiO-66 were well preserved. The B2O3 species are wrapped by WO3 species, thus increasing the polymeric degree of the WO3 species, which are mainly located in low-condensed oligomeric environments. Moreover, when compared with WO3/UiO-66, the B2O3-WO3/UiO-66 material has a little weaker acidity, which decreased by 10% upon the B2O3 introduction. The as-obtained novel material exhibits higher catalytic performance in the cyclopentene selective oxidation to glutaraldehyde than WO3/UiO-66. The high catalytic performance was attributed to a proper amount of B2O3 and WO3 with an appropriate acidity, their high dispersion, and the synergistic effects between them. In addition, these oxide species hardly leached in the reaction solution, endowing the catalyst with a good stability. The catalyst could be used for six reaction cycles without an obvious loss of catalytic activity. PMID- 30274395 TI - Point Score Systems and Cooperative Incentives: The 3-1-0 Curse. AB - The purpose of this study is to analyze the consequences that point score systems in association football may have on potential collusion between teams. The study applies game theory and empirical analysis to derive and test hypotheses. The main findings of the article include Nash equilibria indicating a higher collusion potential associated with the 3-1-0 point score system than with the 2 1-0 system. Of particular interest is the finding that the competitive balance of the league affects collusion, and that (theoretically) high competitive balance in fact makes collusion more probable. Empirically, we are not able to prove that real-world participants do collude, but we provide circumstantial evidence that is consistent with collusion. The empirical analysis is based on a sample of 25 European top leagues with 823 played matches in the 2017 and 2016/17 seasons. These data are used to estimate uncertainty of outcome and draw ratio. We apply a standard t-test to test our main hypothesis. The main conclusion of the paper may hence be summed up as advice to reinstall the 2-1-0 point score system in association football. PMID- 30274393 TI - Teacher Discrimination Reduces School Performance of African American Youth: Role of Gender. AB - : Background: Gender may alter African Americans' vulnerability to discrimination. The type of outcomes that follow exposure to discrimination may also be gender-specific. Although teacher discrimination is known to deteriorate school performance, it is yet unknown whether male and female African American youth differ in the effect of teacher discrimination on school performance. Objective: This cross-sectional study explored the moderating role of gender on the effect of teacher discrimination on school performance in a national sample of African American youth. Methods: The National Survey of American Life Adolescent Supplement (NSAL-A) enrolled a nationally representative sample (n = 810) of 13-17-year-old African American youth. Demographic factors, socioeconomic status, teacher discrimination, and school performance (grade point average, GPA) were measured. Linear multivariable regression models were applied for data analysis. RESULTS: Males and females reported similar levels of perceived teacher discrimination. In the pooled sample, higher teacher discrimination was associated with lower school performance among African American youth (b = -0.35; 95% confidence interval (CI) = -0.49 to -0.22). Gender interacted with perceived teacher discrimination (b = 12; 95% CI = 0.24-2.02), suggesting a significant difference between males and females in the magnitude of the association between perceived teacher discrimination and GPA. In stratified models, perceived teacher discrimination was associated with worse school performance of females (b = -12; 95% CI = -0.03 to -2.78) but not males (b = 0.01; 95% CI = -0.07 to 0.08). CONCLUSION: In line with previous studies, gender was found to alter the vulnerability of African American youth to perceived discrimination. African American boys and girls may differ in their sensitivity to the effects of teacher discrimination on school performance. PMID- 30274394 TI - Human Mesenchymal Stem Cell Secretome from Bone Marrow or Adipose-Derived Tissue Sources for Treatment of Hypoxia-Induced Pulmonary Epithelial Injury. AB - : : Alveolar epithelial dysfunction induced by hypoxic stress plays a significant role in the pathological process of lung ischemia-reperfusion injury (IRI). Mesenchymal stem cell (MSC) therapies have demonstrated efficacy in exerting protective immunomodulatory effects, thereby reducing airway inflammation in several pulmonary diseases. AIM: This study assesses the protective effects of MSC secretome from different cell sources, human bone marrow (BMSC) and adipose tissue (ADSC), in attenuating hypoxia-induced cellular stress and inflammation in pulmonary epithelial cells. METHODS: Pulmonary epithelial cells, primary rat alveolar epithelial cells (AEC) and A549 cell line were pre-treated with BMSC, or ADSC conditioned medium (CM) and subjected to hypoxia for 24 h. RESULTS: Both MSC CM improved cell viability, reduced secretion of pro-inflammatory mediators and enhanced IL-10 anti-inflammatory cytokine production in hypoxic injured primary rat AECs. ADSC-CM reduced hypoxic cellular injury by mechanisms which include: inhibition of p38 MAPK phosphorylation and nuclear translocation of subunits in primary AECs. Both MSC-CM enhanced translocation of Bcl-2 to the nucleus, expression of cytoprotective glucose-regulated proteins (GRP) and restored matrix metalloproteinases (MMP) function, thereby promoting repair and cellular homeostasis, whereas inhibition of GRP chaperones was detrimental to cell survival. CONCLUSIONS: Elucidation of the protective mechanisms exerted by the MSC secretome is an essential step for maximizing the therapeutic effects, in addition to developing therapeutic targets-specific strategies for various pulmonary syndromes. PMID- 30274396 TI - An Improved Strapdown Inertial Navigation System Initial Alignment Algorithm for Unmanned Vehicles. AB - Along with the development of computer technology and informatization, the unmanned vehicle has become an important equipment in military, civil and some other fields. The navigation system is the basis and core of realizing the autonomous control and completing the task for unmanned vehicles, and the Strapdown Inertial Navigation System (SINS) is the preferred due to its autonomy and independence. The initial alignment technique is the premise and the foundation of the SINS, whose performance is susceptible to system nonlinearity and uncertainty. To improving system performance for SINS, an improved initial alignment algorithm is proposed in this manuscript. In the procedure of this presented initial alignment algorithm, the original signal of inertial sensors is denoised by utilizing the improved signal denoising method based on the Empirical Mode Decomposition (EMD) and the Extreme Learning Machine (ELM) firstly to suppress the high-frequency noise on coarse alignment. Afterwards, the accuracy and reliability of initial alignment is further enhanced by utilizing an improved Robust Huber Cubarure Kalman Filer (RHCKF) method to minimize the influence of system nonlinearity and uncertainty on the fine alignment. In addition, real tests are used to verify the availability and superiority of this proposed initial alignment algorithm. PMID- 30274397 TI - Altered Proteins in the Hippocampus of Patients with Mesial Temporal Lobe Epilepsy. AB - Mesial temporal lobe epilepsy (MTLE) is usually associated with drug-resistant seizures and cognitive deficits. Efforts have been made to improve the understanding of the pathophysiology of MTLE for new therapies. In this study, we used proteomics to determine the differential expression of proteins in the hippocampus of patients with MTLE compared to control samples. By using the two dimensional electrophoresis method (2-DE), the proteins were separated into spots and analyzed by LC-MS/MS. Spots that had different densitometric values for patients and controls were selected for the study. The following proteins were found to be up-regulated in patients: isoform 1 of serum albumin (ALB), proton ATPase catalytic subunit A (ATP6V1A), heat shock protein 70 (HSP70), dihydropyrimidinase-related protein 2 (DPYSL2), isoform 1 of myelin basic protein (MBP), and dihydrolipoamide S-acethyltransferase (DLAT). The protein isoform 3 of the spectrin alpha chain (SPTAN1) was down-regulated while glutathione S transferase P (GSTP1) and protein DJ-1 (PARK7) were found only in the hippocampus of patients with MTLE. Interactome analysis of the nine proteins of interest revealed interactions with 20 other proteins, most of them involved with metabolic processes (37%), presenting catalytic activity (37%) and working as hydrolyses (25%), among others. Our results provide evidence supporting a direct link between synaptic plasticity, metabolic disturbance, oxidative stress with mitochondrial damage, the disruption of the blood-brain barrier and changes in CNS structural proteins with cell death and epileptogenesis in MTLE. Besides this, the presence of markers of cell survival indicated a compensatory mechanism. The over-expression of GSTP1 in MTLE could be related to drug resistance. PMID- 30274398 TI - Traceability of "Tuscan PGI" Extra Virgin Olive Oils by 1H NMR Metabolic Profiles Collection and Analysis. AB - According to Coldiretti, Italy still continues to hold the European Quality record in extra virgin olive oils with origin designation and protected geographical indication (PDO and PGI). To date, 46 Italian brands are recognized by the European Union: 42 PDO and 4 PGI (Tuscan PGI, Calabria PGI; Tuscia PGI and PGI Sicily). Specific regulations, introduced for these quality marks, include the designation of both the geographical areas and the plant varieties contributing to the composition of the olive oil. However, the PDO and PGI assessment procedures are currently based essentially on farmer declarations. Tuscan PGI extra virgin olive oil is one of the best known Italian trademarks around the world. Tuscan PGI varietal platform is rather wide including 31 specific olive cultivars which should account for at least 95% of the product. On the other hand, while the characteristics of other popular Italian extra virgin olive oils (EVOOs) cultivars from specific geographical areas have been extensively studied (such as those of Coratina based blends from Apulia), little is still known about Tuscan PGI EVOO constituents. In this work, we performed, for the first time, a large-scale analysis of Tuscan PGI monocultivar olive oils by 1H NMR spectroscopy and multivariate statistical analyses (MVA). After genetic characterization of 217 leaf samples from 24 selected geographical areas, distributed all over the Tuscany, a number of 202 micro-milled oil samples including 10 PGI cultivars, was studied. The results of the present work confirmed the need of monocultivar genetically certified EVOO samples for the construction of 1H-NMR-metabolic profiles databases suitable for cultivar and/or geographical origin assessment. Such specific PGI EVOOs databases could be profitably used to justify the high added value of the product and the sustainability of the related supply chain. PMID- 30274399 TI - Neuronal Activity-Dependent Activation of Astroglial Calcineurin in Mouse Primary Hippocampal Cultures. AB - Astrocytes respond to neuronal activity by generating calcium signals which are implicated in the regulation of astroglial housekeeping functions and/or in modulation of synaptic transmission. We hypothesized that activity-induced calcium signals in astrocytes may activate calcineurin (CaN), a calcium/calmodulin-regulated protein phosphatase, implicated in neuropathology, but whose role in astroglial physiology remains unclear. We used a lentiviral vector expressing NFAT-EYFP (NY) fluorescent calcineurin sensor and a chemical protocol of LTP induction (cLTP) to show that, in mixed neuron-astrocytic hippocampal cultures, cLTP induced robust NY translocation into astrocyte nuclei and, hence, CaN activation. NY translocation was abolished by the CaN inhibitor FK506, and was not observed in pure astroglial cultures. Using Fura-2 single cell calcium imaging, we found sustained Ca2+ elevations in juxtaneuronal, but not distal, astrocytes. Pharmacological analysis revealed that both the Ca2+ signals and the nuclear NY translocation in astrocytes required NMDA and mGluR5 receptors and depended on extracellular Ca2+ entry via a store-operated mechanism. Our results provide a proof of principle that calcineurin in astrocytes may be activated in response to neuronal activity, thereby delineating a framework for investigating the role of astroglial CaN in the physiology of central nervous system. PMID- 30274400 TI - The Re-Emergence and Emergence of Vector-Borne Rickettsioses in Taiwan. AB - Rickettsial diseases, particularly vector-borne rickettsioses (VBR), have a long history in Taiwan, with studies on scrub typhus and murine typhus dating back over a century. The climatic and geographic diversity of Taiwan's main island and its offshore islands provide many ecological niches for the diversification and maintenance of rickettsiae alike. In recent decades, scrub typhus has re-emerged as the most prevalent type of rickettsiosis in Taiwan, particularly in eastern Taiwan and its offshore islands. While murine typhus has also re-emerged on Taiwan's western coast, it remains neglected. Perhaps more alarming than the re emergence of these rickettsioses is the emergence of newly described VBR. The first case of human infection with Rickettsia felis was confirmed in 2005, and undetermined spotted fever group rickettsioses have recently been detected. Taiwan is at a unique advantage in terms of detecting and characterizing VBR, as it has universal health coverage and a national communicable disease surveillance system; however, these systems have not been fully utilized for this purpose. Here, we review the existing knowledge on the eco-epidemiology of VBR in Taiwan and recommend future courses of action. PMID- 30274403 TI - Mosquitoes and the Lymphatic Filarial Parasites: Research Trends and Budding Roadmaps to Future Disease Eradication. AB - The mosquito-borne lymphatic filariasis (LF) is a parasitic, neglected tropical disease that imposes an unbearable human scourge. Despite the unprecedented efforts in mass drug administration (MDA) and morbidity management, achieving the global LF elimination slated for the year 2020 has been thwarted by limited MDA coverage and ineffectiveness in the chemotherapeutic intervention. Moreover, successful and sustainable elimination of mosquito-vectored diseases is often encumbered by reintroduction and resurgence emanating from human residual or new infections being widely disseminated by the vectors even when chemotherapy proves effective, but especially in the absence of effective vaccines. This created impetus for strengthening the current defective mosquito control approach, and profound research in vector-pathogen systems and vector biology has been pushing the boundaries of ideas towards developing refined vector-harnessed control strategies. Eventual implementation of these emerging concepts will offer a synergistic approach that will not only accelerate LF elimination, but also augurs well for its future eradication. This brief review focuses on advances in mosquito-filaria research and considers the emerging prospects for future eradication of LF. PMID- 30274401 TI - Suspected and Confirmed Vector-Borne Rickettsioses of North America Associated with Human Diseases. AB - The identification of pathogenic rickettsial agents has expanded over the last two decades. In North America, the majority of human cases are caused by tick borne rickettsioses but rickettsiae transmitted by lice, fleas, mites and other arthropods are also responsible for clinical disease. Symptoms are generally nonspecific or mimic other infectious diseases; therefore, diagnosis and treatment may be delayed. While infection with most rickettsioses is relatively mild, delayed diagnosis and treatment may lead to increased morbidity and mortality. This review will discuss the ecology, epidemiology and public health importance of suspected and confirmed vector-transmitted Rickettsia species of North America associated with human diseases. PMID- 30274402 TI - Tick-, Flea-, and Louse-Borne Diseases of Public Health and Veterinary Significance in Nigeria. AB - Mosquito-borne diseases are common high-impact diseases in tropical and subtropical areas. However, other non-mosquito vector-borne pathogens (VBPs) may share their geographic distribution, seasonality, and clinical manifestations, thereby contributing their share to the morbidity and mortality caused by febrile illnesses in these regions. The purpose of this work was to collect and review existing information and identify knowledge gaps about tick, flea-, and louse borne diseases of veterinary and public health significance in Nigeria. Full length articles about VBPs were reviewed and relevant information about the vectors, their hosts, geographic distribution, seasonality, and association(s) with human or veterinary diseases was extracted. Specific laboratory tools used for detection and identification of VBPs in Nigeria were also identified. A total of 62 original publications were examined. Substantial information about the prevalence and impacts of ticks and fleas on pet and service dogs (18 articles), and livestock animals (23 articles) were available; however, information about their association with and potential for causing human illnesses was largely absent despite the zoonotic nature of many of these peri-domestic veterinary diseases. Recent publications that employed molecular methods of detection demonstrated the occurrence of several classic (Ehrlichia canis, Rickettsia africae, Bartonella sp.) and emerging human pathogens (R. aeschlimannii, Neoehrlichia mikurensis) in ticks and fleas. However, information about other pathogens often found in association with ticks (R. conorii) and fleas (R. typhi, R. felis) across the African continent was lacking. Records of louse-borne epidemic typhus in Nigeria date to 1947; however, its current status is not known. This review provides an essential baseline summary of the current knowledge in Nigeria of non-mosquito VBPs, and should stimulate improvements in the surveillance of the veterinary and human diseases they cause in Nigeria. Due to increasing recognition of these diseases in other African countries, veterinary and public health professionals in Nigeria should expand the list of possible diseases considered in patients presenting with fever of unknown etiology. PMID- 30274404 TI - Application of Artificial Neural Networks for Dengue Fever Outbreak Predictions in the Northwest Coast of Yucatan, Mexico and San Juan, Puerto Rico. AB - Modelling dengue fever in endemic areas is important to mitigate and improve vector-borne disease control to reduce outbreaks. This study applied artificial neural networks (ANNs) to predict dengue fever outbreak occurrences in San Juan, Puerto Rico (USA), and in several coastal municipalities of the state of Yucatan, Mexico, based on specific thresholds. The models were trained with 19 years of dengue fever data for Puerto Rico and six years for Mexico. Environmental and demographic data included in the predictive models were sea surface temperature (SST), precipitation, air temperature (i.e., minimum, maximum, and average), humidity, previous dengue cases, and population size. Two models were applied for each study area. One predicted dengue incidence rates based on population at risk (i.e., numbers of people younger than 24 years), and the other on the size of the vulnerable population (i.e., number of people younger than five years and older than 65 years). The predictive power was above 70% for all four model runs. The ANNs were able to successfully model dengue fever outbreak occurrences in both study areas. The variables with the most influence on predicting dengue fever outbreak occurrences for San Juan, Puerto Rico, included population size, previous dengue cases, maximum air temperature, and date. In Yucatan, Mexico, the most important variables were population size, previous dengue cases, minimum air temperature, and date. These models have predictive skills and should help dengue fever mitigation and management to aid specific population segments in the Caribbean region and around the Gulf of Mexico. PMID- 30274405 TI - Clinical Features and Laboratory Findings of Travelers Returning to South Australia with Dengue Virus Infection. AB - Reported cases of dengue are rising in South Australia (SA) in travellers returning from dengue-endemic regions. We have undertaken a retrospective analysis to identify the clinical and laboratory characteristics of patients returning to SA with suspected dengue virus (DENV) infection. From 488 requests, 49 (10%) were defined by serology as acute dengue, with the majority of patients (75%) testing as non-structural protein 1 (NS1) and/or IgM positive. Dengue was most commonly acquired in Indonesia (42.9%) with clinical features of fever (95%), headache (41%) and myalgia/arthralgia (56%). The presence of rash (36%) and laboratory findings of neutropenia, leukopenia, thrombocytopenia, but not elevated C-reactive protein, were distinct from findings in DENV-seronegative patients. Available dengue seropositive samples were analysed by RT-PCR, with 14/32 (43.8%) positive by a serotype non-specific DENV assay, but 28/32 positive (87.5%) when also assessed by serotype-specific RT-PCR. Serotype analysis revealed the predominance of DENV-1 and DENV-2 and the presence of DENV-3, but not DENV-4 or Zika virus (ZIKV). Thus, dengue in returned travellers in SA presents in a manner consistent with World Health Organization (WHO) definitions, with symptoms, travel history and laboratory results useful in prioritising the likelihood of dengue. This definition will assist the future management in DENV non-endemic regions, such as SA. PMID- 30274408 TI - The Rise of Imported Dengue Infections in Victoria, Australia, 2010-2016. AB - Dengue notifications have increased dramatically over the past seven years in Victoria, Australia-a trend which has been seen nationally and reflects increased cases internationally. We reviewed the epidemiology of dengue among Victorian travellers, changes in diagnostic methods and describe the burden placed on local health systems resulting from this disease of public health importance. Cases of dengue notified to the Department of Health and Human Services in Victoria, Australia, between 1 January 2010 and 31 December 2016 were included in this review. Demographic, clinical, diagnostic methods, and risk factor data were examined using descriptive epidemiological analyses. Cases of dengue increased on average by 22% per year, with a total of 2187 cases (5.5 cases/100,000 population) notified over the 7-year reporting period. The most frequently reported country of acquisition was Indonesia (45%) followed by Thailand (14%). The use of multiple diagnostic methods, including the non-structural protein 1 antigen (NS1Ag) detection test, increased over time. The median time between onset of illness and diagnosis diminished from 9 days (IQR: 2-15) in 2010 to 4 days (IQR: 2-7) in 2016. Proportionally more cases were discharged directly from emergency departments in recent years (10% in 2010 to 28% in 2016, p < 0.001).The increasing incidence of dengue in Australia is reflective of its growing prominence as a travel medicine problem in western countries. For travellers with non-severe dengue, the improved timeliness of dengue diagnostics allows for consideration of best practice ambulatory management approaches as used in endemic areas. PMID- 30274409 TI - Scrub Typhus: No Longer Restricted to the Tsutsugamushi Triangle. AB - Scrub typhus is the most important rickettsial disease in the world. Its previous endemic region was considered to be in Asia, Australia and islands in the Indian and Pacific Oceans; this area was referred to as the Tsutsugamushi Triangle. Accumulation of serological, molecular, genetic, and culture data have shown that not only is scrub typhus not limited to the Tsutsugamushi Triangle, but can be caused by orientiae other than Orientia tsutsugamushi. This review describes evidence currently available that will be instrumental to researchers, healthcare providers and medical leaders in developing new research projects, performing diagnosis, and preventing scrub typhus in locations not previously thought to be endemic. PMID- 30274411 TI - Global Burden and Challenges of Melioidosis. AB - Melioidosis, an infectious disease caused by the environmental bacterium Burkholderia pseudomallei, has remained in the shadows for far too long[...]. PMID- 30274407 TI - A Review of Scrub Typhus (Orientia tsutsugamushi and Related Organisms): Then, Now, and Tomorrow. AB - Scrub typhus and the rickettsial diseases represent some of the oldest recognized vector-transmitted diseases, fraught with a rich historical aspect, particularly as applied to military/wartime situations. The vectors of Orientia tsutsugamushi were once thought to be confined to an area designated as the Tsutsugamushi Triangle. However, recent reports of scrub typhus caused by Orientia species other than O. tsutsugamushi well beyond the limits of the Tsutsugamushi Triangle have triggered concerns about the worldwide presence of scrub typhus. It is not known whether the vectors of O. tsutsugamushi will be the same for the new Orientia species, and this should be a consideration during outbreak/surveillance investigations. Additionally, concerns surrounding the antibiotic resistance of O. tsutsugamushi have led to considerations for the amendment of treatment protocols, and the need for enhanced public health awareness in both the civilian and medical professional communities. In this review, we discuss the history, outbreaks, antibiotic resistance, and burgeoning genomic advances associated with one of the world's oldest recognized vector-borne pathogens, O. tsutsugamushi. PMID- 30274410 TI - Rickettsial Infections and Q Fever Amongst Febrile Patients in Bhutan. AB - There is limited evidence of rickettsial diseases in Bhutan. We explored the contribution of rickettsioses as a cause of undifferentiated febrile illness in patients presenting to 14 Bhutanese hospitals from October 2014 to June 2015. Obvious causes of fever were excluded clinically. Clinico-demographic information and acute blood samples were collected. Samples were tested by immunofluorescence assay (IFA) and qPCR against scrub typhus group (STG), spotted fever group (SFG) and typhus group (TG) rickettsiae, and Q fever (QF). Of the 1044 patients, 539 (51.6%) were female and the mean age was 31.5 years. At least 159 (15.2%) of the patients had evidence of a concurrent rickettsial infection. Of these, 70 (6.7%), 46 (4.4%), 4 (0.4%), and 29 (2.8%) were diagnosed as acute infections with STG, SFG, TG, and QF respectively. Ten (1.0%) patients were seropositive for both SFG and TG. Seven of the 70 STG patients were positive by qPCR. Eschar (p < 0.001), myalgia (p = 0.003), and lymphadenopathy (p = 0.049) were significantly associated with STG, but no specific symptoms were associated with the other infections. Disease incidences were not different between age groups, genders, occupations, and districts, except for students with significantly lower odds of infection with STG (OR = 0.43; 95% CI = 0.20, 0.93; p = 0.031). Rickettsioses were responsible for at least 15% of undifferentiated febrile illnesses in Bhutan, scrub typhus being the commonest. Health authorities should ensure that health services are equipped to manage these infections. PMID- 30274412 TI - Development and Clinical Validation of a Multiplex Real-Time Quantitative PCR Assay for Human Infection by Anaplasma phagocytophilum and Ehrlichia chaffeensis. AB - BACKGROUND: Human granulocytic anaplasmosis (HGA), caused by Anaplasma phagocytophilum, and human monocytic ehrlichiosis (HME), caused by Ehrlichia chaffeensis, often present as undifferentiated fever but are not treated by typical empiric regimens for acute febrile illness. Their role as agents of vector-borne febrile disease in tropical regions is more poorly studied than for other rickettsial infections. Limitations in diagnosis have impaired epidemiologic and clinical research and needless morbidity and mortality occur due to untreated illness. METHODS: We designed and clinically validated a multiplex real-time quantitative PCR assay for Anaplasma phagocytophilum and Ehrlichia chaffeensis using samples confirmed by multiple gold-standard methods. RESULTS: Clinical sensitivity and specificity for A. phagocytophilum were 100% (39/39) and 100% (143/143), respectively, and for E. chaffeensis 95% (20/21) and 99% (159/161), respectively. CONCLUSIONS: These assays could support early diagnosis and treatment as well as the high-throughput testing required for large epidemiologic studies. PMID- 30274413 TI - Cross-Cultural, Aboriginal Language, Discovery Education for Health Literacy and Informed Consent in a Remote Aboriginal Community in the Northern Territory, Australia. AB - BACKGROUND: Education for health literacy of Australian Aboriginal people living remotely is challenging as their languages and worldviews are quite different from English language and Western worldviews. Becoming health literate depends on receiving comprehensible information in a culturally acceptable manner. METHODS: The study objective was to facilitate oral health literacy through community education about scabies and strongyloidiasis, including their transmission and control, preceding an ivermectin mass drug administration (MDA) for these diseases. A discovery education approach where health concepts are connected to cultural knowledge in the local language was used. Aboriginal and non-Aboriginal educators worked collaboratively to produce an in-depth flip-chart of the relevant stories in the local language and to share them with clan elders and 27% of the population. RESULTS: The community health education was well received. Feedback indicated that the stories were being discussed in the community and that the mode of transmission of strongyloidiasis was understood. Two-thirds of the population participated in the MDA. This study documents the principles and practice of a method of making important Western health knowledge comprehensible to Aboriginal people. This method would be applicable wherever language and culture of the people differ from language and culture of health professionals. PMID- 30274414 TI - Community Awareness on Rabies Prevention and Control in Bicol, Philippines: Pre- and Post-Project Implementation. AB - Rabies is endemic in the Philippines. To support the rabies campaign in the Bicol region at the southeastern part of Luzon, the BAI-OIE Stop Transboundary Animal Diseases and Zoonoses (STANDZ) Rabies project was implemented in the pilot provinces of Camarines Norte, Camarines Sur, Albay, and Masbate. A community awareness survey was conducted with the residents of these provinces to determine their knowledge, attitude, and practices (KAP) on rabies during the start and end of the project. Qualitative, descriptive research was done with a structured KAP questionnaire. Pet owners in the pilot provinces were chosen as respondents. Results showed that respondents know that they can acquire rabies in animals through the bite of a rabid dog (pre-project implementation (PRI): 19.6%, post project implementation (POI): 38.0%). Vaccination was the top rabies preventive measure (PRI: 61.8%, POI: 92.8%). Biting incidents were noted in some respondents, and observing the dog and killing it immediately were some of the actions taken by bite victims. If a supposed rabid dog was seen, respondents would either: immediately kill the dog (PRI: 20.3%, POI: 13.7%), report it to authorities (PRI: 26.3%, POI: 63.1%), and capture and observe the dog concerned (PRI: 13.5%, POI: 6.0%). Pet owners increased their KAP about rabies prevention and control as compared to the pre-implementation study. However, certain gaps in their KAP need to be given attention; thus continuous education of pet owners must be done. PMID- 30274415 TI - The 'Influenza' Vaccine Used during the Samoan Pandemic of 1918. AB - In 1918, a crude influenza vaccine made from chemically inactivated, mixed cultures of respiratory bacteria was widely used prior to the understanding that influenza was caused by a virus. Such vaccines contained no viral material and probably consisted largely of bacterial endotoxin. The Australian military used such a vaccine on Samoa in December 1918 and thought it was valuable. Post hoc analyses suggest that the mixed respiratory bacteria vaccine may have actually been of some benefit, but the mechanism of such protection is unknown. Although such a crude vaccine would not be considered in a modern setting, the rapid use of problematic vaccines still remains a risk when new influenza types suddenly appear, as in 1976 and 2009. PMID- 30274416 TI - Use of Intermittent Preventive Treatment among Pregnant Women in Sub-Saharan Africa: Evidence from Malaria Indicator Surveys. AB - Uptake of intermittent preventive therapy in pregnancy (IPTp) with sulfadoxine pyrimethamine (IPTp-SP) is a clinically-proven method to prevent the adverse outcomes of malaria in pregnancy (MiP) for the mother, her foetus, and the neonates. The majority of countries in sub-Saharan Africa have introduced IPTp policies for pregnant women during the past decade. Nonetheless, progress towards improving IPTp coverage remains dismal, with widespread regional and socioeconomic disparities in the utilisation of this highly cost-effective service. In the present study, our main objective was to measure the prevalence of IPTp uptake in selected malaria-endemic countries in sub-Saharan Africa, and to investigate the patterns of IPTp uptake among different educational and wealth categories adjusted for relevant sociodemographic factors. For this study, cross sectional data on 18,603 women aged between 15 and 49 years were collected from the Malaria Indicator Surveys (MIS) conducted in Burkina Faso, Ghana, Mali, Malawi, Kenya, Nigeria, Sierra Leone, and Uganda. The outcome variable was taking three doses of IPTp-SP in the last pregnancy, defined as adequate by the WHO. According to the analysis, the overall prevalence of taking three doses of IPTp SP in the latest pregnancy was 29.5% (95% CI = 28.2-30.5), with the prevalence being highest for Ghana (60%, 95% CI = 57.1-62.8), followed by Kenya (37%, 95% CI = 35.3-39.2) and Sierra Leone (31%, 95% CI = 29.2-33.4). Women from non-poor households (richer-20.7%, middle-21.2%, richest-18.1%) had a slightly higher proportion of taking three doses of IPTp-SP compared with those from poorest (19.0%) and poorer (21.1%) households. Regression analysis revealed an inverse association between uptake of IPTp-SP and educational level. With regard to wealth status, compared with women living in the richest households, those in the poorest, poorer, middle, and richer households had significantly higher odds of not taking at least three doses of IPTp-SP during their last pregnancy. The present study concludes that the prevalence of IPTp-SP is still alarmingly low and is significantly associated with individual education and household wealth gradient. Apart from the key finding of socioeconomic disparities within countries, were the between-country variations that should be regarded as a marker of inadequate policy and healthcare system performance in the respective countries. More in-depth and longitudinal studies are required to understand the barriers to, and preferences of, using IPTp-SP among women from different socioeconomic backgrounds. PMID- 30274417 TI - Hemophagocytic Lymphohistiocytosis Associated with Scrub Typhus: Systematic Review and Comparison between Pediatric and Adult Cases. AB - BACKGROUND: Scrub typhus is a mite-borne bacterial infection caused by Orientia tsutsugamushi. Hemophagocytic lymphohistiocytosis (HLH) is a potential severe complication. Most reported cases of HLH associated with scrub typhus were single cases or case series with a small sample sizes. Thus, no clear consensus exists on clinical manifestations and differences between pediatric and adult cases of this condition. METHODS: a systematic search of English and Japanese articles from PubMed, PubMed Central, and Directory of Open Access Journals databases was performed from 3 December 2016 to 28 December 2017. The primary outcome was mortality in patients with HLH associated with scrub typhus; secondary outcomes were differences in clinical symptoms, laboratory findings, and treatment between pediatric and adult patients with HLH associated with scrub typhus. RESULTS: thirty cases of HLH associated with scrub typhus were identified (age range: 2 months to 75 years; median age: 21.5 years, male:female ratio, 1:1). Eschar was frequently observed in the pediatric group (p = 0.017), whereas acute kidney injury was more prevalent in the adult group (p = 0.010). Two patients died of intracranial hemorrhage complicated with multiple organ failure; overall mortality rate was 6.7%. CONCLUSIONS: HLH associated with scrub typhus could be cured with remarkable improvement using single antibiotic therapy in approximately half the cases, with the mortality rate being relatively lower than that of HLH associated with other secondary causes. PMID- 30274418 TI - Melioidosis in Brunei Darussalam. AB - Melioidosis continues to be a major health care problem in Brunei Darussalam. The age of patients, gender distribution, risk factors, and clinical presentations are similar to those reported from other countries in the region. The incidence of melioidosis was high during the wet months and in the Temburong district, which has the highest annual rainfall. In spite of adequate facilities for diagnosis and treatment, the mortality remains high (27%). Women and those presenting with septic shock had higher mortality. There is a case for making melioidosis a notifiable disease in Brunei Darussalam. Coordinated efforts between policy-makers and various stakeholders are required to effectively combat the disease. PMID- 30274420 TI - Melioidosis in Sri Lanka. AB - Until recently, Sri Lanka was not considered a country with endemic melioidosis. However, an increasing number of cases is being reported. National surveillance for melioidosis was instituted after 2008. A total of 250 culture-positive cases was recorded between 2006 and May 2017. Males predominated (71.6%). The age range was wide (2-92 years) reflecting a ubiquity of exposure. The majority (201/250, 80%) lived in rural areas. All provinces were affected. Case load increased during the two monsoonal periods (67%). There was representation of every population group including farmers (n = 44), housewives (n = 24), school children (n = 10), professionals (n = 5), businesspersons (n = 6), white-collar workers (n = 10) and blue-collar workers (n = 8). Diabetes was the predominant risk factor (n = 163, 65.2%). Clinical presentations included community-acquired sepsis and pneumonia, superficial and deep abscesses, and septic arthritis. Mortality was 20.4% (51/250). A majority (n = 212) of isolates belonged to the YLF (Yersinia like fimbrial) clade but 38 were BTFC (B. thailandensis-like flagellum and chemotaxis). A total of 108 isolates was genotyped and 46 sequence types (STs) were identified, 40 being novel. It is clear that melioidosis is endemic in Sri Lanka with a wide geographic and demographic distribution. There is an urgent need to extend surveillance of melioidosis to under-resourced parts of the country and to populations at high risk. PMID- 30274419 TI - Melioidosis in the Lao People's Democratic Republic. AB - Melioidosis is clearly highly endemic in Laos, although the disease has only been diagnosed regularly in humans (1359 cases) since 1999, and only a single animal case has been microbiologically confirmed. Burkholderia pseudomallei is extensively and abundantly present in soil and surface water in central and southern Laos, but the true distribution of the disease across the country remains to be determined. Surveillance is almost non-existent and diagnostic microbiology services are not yet well established, whilst awareness of melioidosis is low amongst policy-makers, healthcare providers, and the public. It is hoped that this situation will improve over the next decade as the country rapidly develops, especially as this is likely to be accompanied by a further increase in the prevalence of diabetes, meaning that more people in this predominantly agricultural population will be at risk of contracting melioidosis. PMID- 30274421 TI - A Report from the Cambodia Training Event for Awareness of Melioidosis (C-TEAM), October 2017. AB - Melioidosis is an endemic infection in Cambodia, a lower middle income SE Asian country. Despite more laboratories isolating and identifying Burkholderia pseudomallei in recent years, the infection remains under-recognised and under diagnosed, particularly in the adult population. Lack of knowledge about the disease and lack of utilization of microbiology laboratories contributes to this, along with laboratory capacity issues. Treatment costs often hamper optimal management. In response to these issues, a national one-health training event was held in October 2017 to raise awareness of the disease amongst clinical, laboratory, and public health professionals. The meeting format, findings, and outcomes are described here. PMID- 30274422 TI - Melioidosis in Malaysia: Incidence, Clinical Challenges, and Advances in Understanding Pathogenesis. AB - Malaysia is an endemic hot spot for melioidosis; however, a comprehensive picture of the burden of disease, clinical presentations, and challenges faced in diagnosis and treatment of melioidosis is not available. This review provides a nonexhaustive overview of epidemiological data, clinical studies, risk factors, and mortality rates from available literature and case reports. Clinical patterns of melioidosis are generally consistent with those from South and Southeast Asia in terms of common primary presentations with diabetes as a major risk factor. Early diagnosis and appropriate management of Malaysian patients is a key limiting factor, which needs to be addressed to reduce serious complications and high mortality and recurrence rates. Promoting awareness among the local healthcare personnel is crucial to improving diagnostics and early treatment, as well as educating the Malaysian public on disease symptoms and risk factors. A further matter of urgency is the need to make this a notifiable disease and the establishment of a national melioidosis registry. We also highlight local studies on the causative agent, Burkholderia pseudomallei, with regards to bacteriology and identification of virulence factors as well as findings from host-pathogen interaction studies. Collectively, these studies have uncovered new correlations and insights for further understanding of the disease. PMID- 30274423 TI - Transmission Modes of Melioidosis in Taiwan. AB - In Taiwan, melioidosis is an emerging disease that suddenly increased in the Er Ren River Basin, beginning in 2005 and in the Zoynan region during 2008-2012, following a typhoon. Additionally, the disease sporadically increased in a geography-dependent manner in 2016. Subcutaneous inoculation, ingestion, and the inhalation of soil or water contaminated with Burkholderia pseudomallei are recognized as the transmission modes of melioidosis. The appearance of environmental B. pseudomallei positivity in northern, central and southern Taiwan is associated with disease prevalence (cases/population: 0.03/100,000 in the northern region, 0.29/100,000 in the central region and 1.98/100,000 in the southern region). However, melioidosis-clustered areas are confined to 5 to 7.5 km2 hot spots containing high-density populations, but B. pseudomallei contaminated environments are located >5 km northwestern of the periphery of these hot spots. The observation that the concentration of B. pseudomallei specific DNA in aerosols was positively correlated with the incidence of melioidosis and the appearance of a northwesterly wind in a hot spot indicated that airborne transmission had occurred in Taiwan. Moreover, the isolation rate in the superficial layers of a contaminated crop field in the northwest was correlated with PCR positivity in aerosols collected from the southeast over a two-year period. The genotype ST58 was identified by multilocus sequence typing in human and aerosol isolates. The genotype ST1001 has increased in prevalence but has been sporadically distributed elsewhere since 2016. These data indicate the transmission modes and environmental foci that support the dissemination of melioidosis are changing in Taiwan. PMID- 30274425 TI - Melioidosis in Myanmar. AB - Sporadic cases of melioidosis have been diagnosed in Myanmar since the disease was first described in Yangon in 1911. Published and unpublished cases are summarized here, along with results from environmental and serosurveys. A total of 298 cases have been reported from seven states or regions between 1911 and 2018, with the majority of these occurring before 1949. Findings from soil surveys confirm the presence of Burkholderia pseudomallei in the environment in all three regions examined. The true epidemiology of the disease in Myanmar is unknown. Important factors contributing to the current gaps in knowledge are lack of awareness among clinicians and insufficient laboratory diagnostic capacity in many parts of the country. This is likely to have led to substantial under reporting. PMID- 30274426 TI - Spotted Fever Rickettsiosis in a Wildlife Researcher in Sabah, Malaysia: A Case Study. AB - We present evidence for a case of spotted fever rickettsiosis with severe complications in a young adult male. Although spotted fever group rickettsiae (SFGR) have been reported as the most prevalent cause of rickettsiosis in rural areas of Sabah, Malaysia since the 1980s, this is the first detailed case report of suspected SFGR in the state. Current data on the prevalence, type, and thorough clinical reports on complications of SFGR and other rickettsioses in Sabah is lacking and required to raise the awareness of such diseases. There is a need to emphasize the screening of rickettsioses to medical personnel and to encourage the use of appropriate antibiotics as early treatment for nonspecific febrile illnesses in this region. Suspected rickettsioses need to be considered as one of the differential diagnoses for patients presenting with acute febrile illness for laboratory investigations, and early treatment instituted. PMID- 30274424 TI - Melioidosis: An Australian Perspective. AB - Burkholderia pseudomallei is endemic in northern Australia, with cases of melioidosis most commonly occurring during the wet season in individuals with diabetes, hazardous alcohol use, and chronic kidney disease. Pneumonia is the most common presentation and the majority of patients are bacteraemic-however, infection may involve almost any organ, with the skin and soft tissues, genitourinary system, visceral organs, and bone and joints affected most commonly. Central nervous system involvement is rarer, but has a high attributable mortality. Increased awareness of the disease amongst healthcare providers, ready access to appropriate antibiotic therapy and high-quality intensive care services has resulted in a sharp decline in the case fatality rate over the last 20 years. Further improvement in clinical outcomes will require a greater understanding of the disease's pathophysiology, its optimal management, and more effective strategies for its prevention. PMID- 30274427 TI - Melioidosis in the Western Indian Ocean and the Importance of Improving Diagnosis, Surveillance, and Molecular Typing. AB - Melioidosis, caused by the bacterium Burkholderia pseudomallei, is an infectious disease of humans or animals, and the specific environmental conditions that are present in western Indian Ocean islands are particularly suitable for the establishment/survival of B. pseudomallei. Indeed, an increasing number of new cases have been reported in this region (Madagascar, Mauritius, Reunion (France), and Seychelles, except Comoros and Mayotte (France)), and are described in this review. Our review clearly points out that further studies are needed in order to investigate the real incidence and burden of melioidosis in the western Indian Ocean and especially Madagascar, since it is likely to be higher than currently reported. Thus, research and surveillance priorities were recommended (i) to improve awareness of melioidosis in the population and among clinicians; (ii) to improve diagnostics, in order to provide rapid and effective treatment; (iii) to implement a surveillance and reporting system in the western Indian Ocean; and (iv) to investigate the presence of B. pseudomallei in environmental samples, since we have demonstrated its presence in soil samples originating from the yard of a Madagascan case. PMID- 30274430 TI - A Tool for Assessment of Animal Health Laboratory Safety and Biosecurity: The Safety Module of the Food and Agriculture Organization's Laboratory Mapping Tool. AB - The Laboratory Management Tool (LMT) is a standardized spreadsheet-based assessment tool developed to help support national, regional, and global efforts to maintain an effective network of animal health and veterinary public health laboratories. The safety and biosecurity module of the LMT (LMT-S) includes 98 measures covering administrative, operational, engineering, and personal protective equipment practices used to provide laboratory safety and biosecurity. Performance aspects of laboratory infrastructure and technical compliance considered fundamental for ensuring that a laboratory is able to appropriately function in a safe and biosecure manner are systematically queried and scored for compliance on a four-point scale providing for a semi-quantitative assessment. Data collected is used to generate graphs and tables mapping levels of compliance with international standards and good practices, as well as for documenting progress over time. The LMT-S was employed by trained auditors in 34 laboratories located in 19 countries between 2015 and 2017. The tool is intended to help standardize animal health laboratory assessments, document compliance with recognized laboratory safety and biosecurity measures, serve as a self-help and training tool, and assist global laboratory development efforts by providing an accurate measurement of laboratory safety and biosecurity at local, national, and regional levels. PMID- 30274428 TI - Melioidosis in Singapore: Clinical, Veterinary, and Environmental Perspectives. AB - Melioidosis is a notifiable infectious disease registered with the Ministry of Health (MOH) and Agri-Food & Veterinary Authority (AVA), Singapore. From a clinical perspective, increased awareness of the disease has led to early detection and treatment initiation, thus resulting in decreasing mortality rates in recent years. However, the disease still poses a threat to local pet, zoo and farm animals, where early diagnosis is a challenge. The lack of routine environmental surveillance studies also makes prevention of the disease in animals difficult. To date, there have been no reports that provide a complete picture of how the disease impacts the local human and animal populations in Singapore. Information on the distribution of Burkholderia pseudomallei in the environment is also lacking. The aim of this review is to provide a comprehensive overview of both published and unpublished clinical, veterinary and environmental studies on melioidosis in Singapore to achieve better awareness and management of the disease. PMID- 30274429 TI - Emergence of Melioidosis in Indonesia and Today's Challenges. AB - A recent modeling study estimated that there could be as many as 20,000 human melioidosis cases per year in Indonesia, with around 10,000 potential deaths annually. Nonetheless, the true burden of melioidosis in Indonesia is still unknown. The Indonesia Melioidosis Network was formed during the first melioidosis workshop in 2017. Here, we reviewed 101 melioidosis cases (99 human and two animal cases) previously reported and described an additional 45 human melioidosis cases. All 146 culture-confirmed cases were found in Sumatra (n = 15), Java (n = 104), Kalimantan (n = 15), Sulawesi (n = 11) and Nusa Tenggara (n = 1). Misidentification of Burkholderia pseudomallei was not uncommon, and most cases were only recently identified. We also evaluated clinical manifestations and outcome of recent culture-confirmed cases between 2012 and 2017 (n = 42). Overall, 15 (36%) cases were children (age <15 years) and 27 (64%) were adults (age >=15 years). The overall mortality was 43% (18/42). We conducted a survey and found that 57% (327/548) of healthcare workers had never heard of melioidosis. In conclusion, melioidosis is endemic throughout Indonesia and associated with high mortality. We propose that top priorities are increasing awareness of melioidosis amongst all healthcare workers, increasing the use of bacterial culture, and ensuring accurate identification of B. pseudomalleiand diagnosis of melioidosis. PMID- 30274431 TI - Melioidosis in Papua New Guinea and Oceania. AB - Melioidosis has only been sporadically reported throughout Melanesia and the Pacific region since the first report from Guam in 1946; therefore, its contribution to the disease burden in this region is largely unknown. However, the outcome of a small number of active surveillance programs, serological surveys, and presumptive imported cases identified elsewhere provide an insight into its epidemiology and potential significance throughout the region. Both clinical cases and environmental reservoirs have been described from the rural district of Balimo in the Western Province of Papua New Guinea and from the Northern Province of New Caledonia. In both these locations the incidence of disease is similar to that described in tropical Australia and Burkholderia pseudomallei isolates are also phylogenetically linked to Australian isolates. Serological evidence and presumptive imported cases identified elsewhere suggest that melioidosis exists in other countries throughout the Pacific. However, the lack of laboratory facilities and clinical awareness, and the burden of other infections of public health importance such as tuberculosis, contribute to the under-recognition of melioidosis in this region. PMID- 30274432 TI - Salmonella enterica Serovar Typhi: An Unusual Cause of Infective Endocarditis. AB - While typhoid fever is a common infection, Salmonella enterica serovar Typhi is a rare cause of endocarditis. We describe the case of a 20-year-old male who was treated for a primary episode of microbiologically-confirmed typhoid fever. He presented six weeks post-discharge with fever and lethargy. S. Typhi was again identified in blood cultures, and echocardiography identified a mitral valve lesion. Our case suggests that a relapse of typhoid should prompt further investigation for a deep-seated infection, including consideration of echocardiographic evaluation to rule out infective endocarditis. PMID- 30274433 TI - A Review of Laboratory-Acquired Infections in the Asia-Pacific: Understanding Risk and the Need for Improved Biosafety for Veterinary and Zoonotic Diseases. AB - A rapid review was performed to determine (1) the number and causes of reported laboratory-acquired infections (LAI) in the Asia-Pacific region; (2) their significance and threat to the community; (3) the primary risk factors associated with LAIs; (4) the consequences in the event of a LAI or pathogen escape; and (5) to make general recommendations regarding biosafety practices for diagnosis and research in the Asia-Pacific region. A search for LAI and zoonoses in the Asia Pacific region using online search engines revealed a relatively low number of reports. Only 27 LAI reports were published between 1982 and 2016. The most common pathogens associated with LAIs were dengue virus, Arthroderma spp., Brucella spp., Mycobacterium spp., Rickettsia spp., and Shigella spp. Seventy eight percent (21 out of 27 LAI reports) occurred in high-income countries (i.e., Australia, Japan, South Korea, Singapore, and Taiwan) where laboratories were likely to comply with international biosafety standards. Two upper-middle income countries (China (2), and Malaysia (2)) and one lower-middle income country (India (2)) reported LAI incidents. The majority of the reports (fifty-two percent (14/27)) of LAIs occurred in research laboratories. Five LAI reports were from clinical or diagnostic laboratories that are considered at the frontier for zoonotic disease detection. Governments and laboratories in the Asia-Pacific region should be encouraged to report LAI cases as it provides a useful tool to monitor unintended release of zoonotic pathogens and to further improve laboratory biosafety. Non-reporting of LAI events could pose a risk of disease transmission from infected laboratory staff to communities and the environment. The international community has an important and continuing role to play in supporting laboratories in the Asia-Pacific region to ensure that they maintain the safe working environment for the staff and their families, and the wider community. PMID- 30274434 TI - Involvement of Hookworm Co-Infection in the Pathogenesis and Progression of Podoconiosis: Possible Immunological Mechanism. AB - Podoconiosis is an endemic, non-infectious, geochemical and non-filarial inflammatory cause of tropical elephantiasis. The immunology of podoconiosis is not yet expressly understood. In spite of this, co-infection and co-morbidity with the infectious, soil-transmitted hookworm disease that causes iron deficiency anemia has been found to be predominant among affected individuals living in co-endemic settings, thus creating a more complex immunological interplay that still has not been investigated. Although deworming and iron-rich nutrient supplementation have been suggested in podoconiosis patients living under resource-poor conditions, and it is thought that hookworm infection may help to suppress inflammatory responses, the undisputed link that exists between a non-infectious and an infectious disease may create a scenario whereby during a co-infection, treatment of one exacerbates the other disease condition or is dampened by the debilitation caused by the other. In this paper, we elaborate on the immunopathogenesis of podoconiosis and examine the possible immunological dynamics of hookworm co-infection in the immunopathology of podoconiosis, with a view toward improved management of the disease that will facilitate its feasible elimination. PMID- 30274435 TI - Melioidosis in Vietnam: Recently Improved Recognition but still an Uncertain Disease Burden after Almost a Century of Reporting. AB - The first cases of human melioidosis were described in Vietnam in the 1920s, almost a century ago. It was in Vietnam in the thirties that the saprophytic nature of B. pseudomallei was first recognized. Although a significant number of French and U.S. soldiers acquired the disease during the Vietnam wars, indigenous cases in the Vietnamese population were only sporadically reported over many decades. After reunification in 1975, only two retrospective studies reported relatively small numbers of indigenous cases from single tertiary care hospitals located in the biggest cities in the South and the North, respectively. Studies from provincial hospitals throughout the country were missing until the Research Network on Melioidosis and Burkholderia pseudomallei (RENOMAB) project started in 2014. From then on seminars, workshops, and national scientific conferences on melioidosis have been conducted to raise awareness among physicians and clinical laboratory staff. This led to the recognition of a significant number of cases in at least 36 hospitals in 26 provinces and cities throughout Vietnam. Although a widespread distribution of melioidosis has now been documented, there are still challenges to understand the true epidemiology of the disease. Establishment of national guidelines for diagnosis, management, and reporting of the disease together with more investigations on animal melioidosis, genomic diversity of B. pseudomallei and its environmental distribution are required. PMID- 30274436 TI - Melioidosis in Bangladesh: A Clinical and Epidemiological Analysis of Culture Confirmed Cases. AB - Melioidosis is known to occur in Bangladesh, but there are few reports about the condition in the published international literature. We set out to review all known cases of melioidosis in the country to date, using both retrospective and prospective data. A web-based literature search was conducted to identify all published case reports, original articles and conference abstracts. Cases were also included from a prospective study conducted in 2017. Fifty-one cases were identified between 1961 and 2017. Cases have been reported from sixteen out of the 64 districts of Bangladesh. The median age of the patients at presentation was 45 years (IQR 37-52), with a significant male (77%) predominance. Many patients (14/39; 36%) were farmers and 83% had diabetes mellitus. A skin/soft tissue abscess was the most common primary clinical presentation (13/49; 27%), followed by septic arthritis (10/49; 20%), pneumonia, and a deep-seated abscess/organ abscess (7/49; 14%). The major challenges to the diagnosis and treatment of melioidosis in Bangladesh are the lack of resources and the lack of awareness of melioidosis. Capacity development programs are urgently required to define the burden of disease and to tackle the mortality rates. PMID- 30274437 TI - Improving Water, Sanitation and Hygiene Practices, and Housing Quality to Prevent Diarrhea among Under-Five Children in Nigeria. AB - Sub-Saharan Africa as a region accounts for the bulk of the global under-five mortality rate, to which diarrhea is major contributor. Millions of children die from diarrheal diseases each year and those who survive often do so facing suboptimal growth. Preventing the common pathways of transmission for diarrhea causing pathogens, including improved water, sanitation, and hygiene (WASH) are regarded as the most cost-effective measures for tackling this life-threatening disease. This study aimed to quantitatively assess the quality of living arrangement and access to WASH, and their impact on diarrheal outcomes among under-five children in Nigeria. Methods: Data were collected from the 2013 Nigeria Demographic and Health survey (NDHS). Study participants included 28,596 mother-child pairs. Household construction material for wall, floor, and ceiling, access to electricity, and improved water and toilet, were included as the main explanatory variables. Data were analyzed using descriptive and multivariable regression methods. Results: The prevalence of diarrhea was 11.3% (95% CI = 10.2 12.6), with the rate being markedly higher in rural (67.3%) as compared to urban areas (32.7%). In the regression analysis, lacking access to improved toilet and water facilities were associated with 14% and 16% higher odds, respectively, of suffering from diarrhea as compared to those who had improved access. Conclusion: There is evidence of a weak, but statistically significant, relationship between the quality of living environment, including water and sanitation facilities, and diarrhea among under-five children in Nigeria. The study concludes that investing in living conditions and WASH may have potential benefits for child mortality prevention programs in the country. PMID- 30274438 TI - Recent Advances in Next Generation Snakebite Antivenoms. AB - With the inclusion of snakebite envenoming on the World Health Organization's list of Neglected Tropical Diseases, an incentive has been established to promote research and development effort in novel snakebite antivenom therapies. Various technological approaches are being pursued by different research groups, including the use of small molecule inhibitors against enzymatic toxins as well as peptide- and oligonucleotide-based aptamers and antibody-based biotherapeutics against both enzymatic and non-enzymatic toxins. In this article, the most recent advances in these fields are presented, and the advantages, disadvantages, and feasibility of using different toxin-neutralizing molecules are reviewed. Particular focus within small molecules is directed towards the inhibitors varespladib, batimastat, and marimastat, while in the field of antibody-based therapies, novel recombinant polyclonal plantivenom technology is discussed. PMID- 30274440 TI - Towards TB Elimination in Aotearoa/New Zealand: Key Informant Insights on the Determinants of TB among African Migrants. AB - Migrants living in low incidence countries, including New Zealand (NZ), are disproportionately affected by tuberculosis (TB). This foreign-born group poses important challenges to achieving the national TB elimination targets. Thus, the aim of this study was to contribute to the understandingof factors that influence the incidence of TB among African migrants living in NZ. We employed a semi structured interview approach to explore the perceptions of NZ-based African community leaders, health professionals and a non-governmental TB support organisation about the wider determinants of TB. The findings, though not completely generalizable, suggest that many NZ-based Africans endure a difficult process of integration, perceive themselves as least susceptible to TB and have low awareness about available health services. Furthermore, the cost of general practitioner (GP) services, mistrust of health professionals, TB stigma and the NZ immigration policy were indicated as important barriers to TB services. Strategies to address TB among migrants must therefore be more holistic and not be centred on a fragmented approach that overemphasises the biomedical approaches, as the incidence of TB is more likely the outcome of a complex interplay of several underlying factors. PMID- 30274439 TI - A Comparative Assessment of Epidemiologically Different Cutaneous Leishmaniasis Outbreaks in Madrid, Spain and Tolima, Colombia: An Estimation of the Reproduction Number via a Mathematical Model. AB - Leishmaniasis is a neglected tropical disease caused by the Leishmania parasite and transmitted by the Phlebotominae subfamily of sandflies, which infects humans and other mammals. Clinical manifestations of the disease include cutaneous leishmaniasis (CL), mucocutaneous leishmaniasis (MCL) and visceral leishmaniasis (VL) with a majority (more than three-quarters) of worldwide cases being CL. There are a number of risk factors for CL, such as the presence of multiple reservoirs, the movement of individuals, inequality, and social determinants of health. However, studies related to the role of these factors in the dynamics of CL have been limited. In this work, we (i) develop and analyze a vector-borne epidemic model to study the dynamics of CL in two ecologically distinct CL affected regions-Madrid, Spain and Tolima, Colombia; (ii) derived three different methods for the estimation of model parameters by reducing the dimension of the systems; (iii) estimated reproduction numbers for the 2010 outbreak in Madrid and the 2016 outbreak in Tolima; and (iv) compared the transmission potential of the two economically-different regions and provided different epidemiological metrics that can be derived (and used for evaluating an outbreak), once R0 is known and additional data are available. On average, Spain has reported only a few hundred CL cases annually, but in the course of the outbreak during 2009-2012, a much higher number of cases than expected were reported and that too in the single city of Madrid. Cases in humans were accompanied by sharp increase in infections among domestic dogs, the natural reservoir of CL. On the other hand, CL has reemerged in Colombia primarily during the last decade, because of the frequent movement of military personnel to domestic regions from forested areas, where they have increased exposure to vectors. In 2016, Tolima saw an unexpectedly high number of cases leading to two successive outbreaks. On comparing, we estimated reproduction number of the Madrid outbreak to be 3.1 (with range of 2.8-3.9), which was much higher than reproduction number estimates of the Tolima first outbreak 1.2 (with range of 1.1-1.3), and the estimate for the second outbreak in Tolima of 1.019 (with range of 1.018-1.021). This suggests that the epidemic outbreak in Madrid was much more severe than the Tolima outbreak, even though Madrid was economically better-off compared to Tolima. It indicates a potential relationship between urban development and increasing health disparities. PMID- 30274441 TI - First Aid and Pre-Hospital Management of Venomous Snakebites. AB - BACKGROUND: Antivenom is the definitive treatment for venomous snakebites, but is expensive and not available in many rural and poorly developed regions. Timely transportation to facilities that stock and administer antivenom may not be available in rural areas with poorly developed emergency medical services. These factors have led to consideration of measures to delay onset of toxicity or alternatives to antivenom therapy. METHODS: PubMed searches were conducted for articles on snakebite treatment, or that contained first aid, emergency medical services, tourniquets, pressure immobilization bandages, suction devices, and lymphatic flow inhibitors. RESULTS: The reviewed articles describe how venoms spread after a venomous snakebite on an extremity, list the proposed first aid measures for delaying the spread of venoms, and evaluate the scientific studies that support or refute methods of snakebite first aid. The recommendations for field treatment of venomous snakebites will be discussed. CONCLUSIONS: The evidence suggests that pressure immobilization bandages and related strategies are the best interventions to delay onset of systemic toxicity from venomous snakebites but may increase local toxicity for venoms that destroy tissue at the site of the bite, so their use should be individualized to the circumstances and nature of the venom. PMID- 30274442 TI - Strongyloides stercoralis Hyperinfection in an HIV-Infected Patient Successfully Treated with Subcutaneous Ivermectin. AB - A 39-year-old Ethiopian HIV-positive man with peripheral T-cell lymphoma developed Strongyloides stercoralis hyperinfection. The patient was initially treated with oral ivermectin for three weeks without response, most likely due to malabsorption because of concomitant paralytic ileus. Given the persistence of larvae in the body fluids, the worsening respiratory status and clinical malabsorption, veterinary parenteral formulation of ivermectin was administered. The very high plasma concentration of ivermectin achieved in the patient after parenteral administration led to a rapid improvement in his clinical condition and rapid disappearance of the parasite from biological samples, without any adverse reaction. PMID- 30274444 TI - A Community-Directed Integrated Strongyloides Control Program in Queensland, Australia. AB - This paper describes two phases of a community-directed intervention to address strongyloidiasis in the remote Aboriginal community of Woorabinda in central Queensland, Australia. The first phase provides the narrative of a community driven 'treat-and-test' mass drug administration (MDA) intervention that was co designed by the Community Health Service and the community. The second phase is a description of the re-engagement of the community in order to disseminate the key factors for success in the previous MDA for Strongyloides stercoralis, as this information was not shared or captured in the first phase. During the first phase in 2004, there was a high prevalence of strongyloidiasis (12% faecal examination, 30% serology; n = 944 community members tested) that resulted in increased morbidity and at least one death in the community. Between 2004-2005, the community worked in partnership with the Community Health Service to implement a S. stercoralis control program, where all of the residents were treated with oral ivermectin, and repeat doses were given for those with positive S. stercoralis serology. The community also developed their own health promotion campaign using locally-made resources targeting relevant environmental health problems and concerns. Ninety-two percent of the community residents participated in the program, and the prevalence of strongyloidiasis at the time of the 'treat-and test' intervention was 16.6% [95% confidence interval 14.2-19.3]. The cure rate after two doses of ivermectin was 79.8%, based on pre-serology and post-serology tests. The purpose of this paper is to highlight the importance of local Aboriginal leadership and governance and a high level of community involvement in this successful mass drug administration program to address S. stercoralis. The commitment required of these leaders was demanding, and involved intense work over a period of several months. Apart from controlling strongyloidiasis, the community also takes pride in having developed and implemented this program. This appears to be the first community-directed S. stercoralis control program in Australia, and is an important part of the national story of controlling infectious diseases in Indigenous communities. PMID- 30274443 TI - Echinococcus Granulosus Infection in Two Free-Ranging Lumholtz's Tree-Kangaroo (Dendrolagus lumholtzi) from the Atherton Tablelands, Queensland. AB - Infection with the larval stage of the cestode, Echinococcus granulosus sensu lato (s.l.), causes hydatid disease (hydatidosis) in a range of hosts, including macropods and other marsupials, cattle, and humans. Wild macropods are an important sylvatic reservoir for the life cycle of E. granulosus (s.l.) in Australia, and so provide a conduit for transmission of hydatid disease to domestic animals and humans. Two Lumholtz's tree-kangaroos (Dendrolagus lumholtzi) from the Atherton Tablelands of Far North Queensland were recently found to have hydatid cysts in both liver and lung tissues. Tree-kangaroos may travel across the ground between patches of forest but are primarily arboreal leaf-eating macropods. The finding of hydatid cysts in an arboreal folivore may indicate that the area has a high level of contamination with eggs of E. granulosus (s.l.). This finding may be of significance to human health as well as indicating the need for further investigation into the prevalence of hydatid disease in domestic stock, wildlife and humans living in this rapidly urbanizing region. PMID- 30274445 TI - Murray Valley Encephalitis Virus: An Ongoing Cause of Encephalitis in Australia's North. AB - Murray Valley encephalitis virus (MVEV) is a mosquito-borne virus endemic to Australia and New Guinea. Encephalitis due to MVEV is potentially devastating, and no therapeutic interventions of proven value exist. Prevention relies largely on personal protective measures against mosquito bites. We present a case of MVEV encephalitis with a favourable outcome following intensive care management and prolonged rehabilitation, and the epidemiological features of a further 21 cases notified to the health department of Australia's Northern Territory. As cases occur in travellers, and epidemics occur sporadically in south-eastern Australia, clinicians across Australia and further abroad should be familiar with the disease and its diagnosis and management. PMID- 30274446 TI - The Health Effects of Strongyloidiasis on Pregnant Women and Children: A Systematic Literature Review. AB - Strongyloidiasis is a helminth infection that remains under-researched despite its ability to cause significant illness. Women and children may be at particular risk of health consequences from this parasite. This systematic literature review aims to examine research on the long-term health effects that strongyloidiasis has in pregnant women and children. We conducted a structured search using multiple databases to collect all primary studies discussing health effects of strongyloidiasis in the aforementioned groups. The review included 20 results: 16 primary studies and four case reports. The methodological quality of studies was substandard, and there was substantial heterogeneity to the statistical analysis and outcomes assessed in the literature. Statistically significant associations were found between strongyloidiasis and low birth weight, as well as wasting. No links were found between strongyloidiasis and anaemia. Due to testing methods used in the studies, the prevalence of Strongyloides stercoralis in these studies was probably under-estimated. Current research is suggestive that strongyloidiasis has long-term adverse health effects on the offspring of infected mothers and in chronically-infected children. Data analysis was hindered by both methodological and statistical flaws, and as such, reliable conclusions regarding the health impacts could not be formed. PMID- 30274448 TI - Immunisation Rates of Medical Students at a Tropical Queensland University. AB - Although medical students are at risk of contracting and transmitting communicable diseases, previous studies have demonstrated sub-optimal medical student immunity. The objective of this research was to determine the documented immunity of medical students at James Cook University to important vaccine preventable diseases. An anonymous online survey was administered thrice in 2014, using questions with categories of immunity to determine documented evidence of immunity, as well as closed-ended questions about attitudes towards the importance of vaccination. Of the 1158 medical students targeted via survey, 289 responses were included in the study (response rate 25%), of which 19 (6.6%) had documented evidence of immunity to all of the vaccine-preventable diseases surveyed. Proof of immunity was 38.4% for seasonal influenza, 47.1% for pertussis, 52.2% for measles, 38.8% for varicella, 43.7% for hepatitis A, and 95.1% for hepatitis B (the only mandatory vaccination for this population). The vast majority of students agreed on the importance of vaccination for personal protection (98.3%) and patient protection (95.9%). In conclusion, medical students have sub-optimal evidence of immunity to important vaccine-preventable diseases. Student attitudes regarding the importance of occupational vaccination are inconsistent with their level of immunity. The findings of this study were used to prompt health service and educational providers to consider their duty of care to manage the serious risks posed by occupational communicable diseases. PMID- 30274447 TI - Melioidosis in South Asia (India, Nepal, Pakistan, Bhutan and Afghanistan). AB - Despite the fact that South Asia is predicted to have the highest number of cases worldwide, melioidosis is a little-known entity in South Asian countries. It has never been heard of by the majority of doctors and has as yet failed to gain the attention of national Ministries of Health and country offices of the World Health Organization (WHO). Although a few centers are diagnosing increasing numbers of cases, and the mortality documented from these institutions is relatively high (nearly 20%), the true burden of the disease remains unknown. In India, most cases have been reported from southwestern coastal Karnataka and northeastern Tamil Nadu, although this probably simply reflects the presence of centers of excellence and researchers with an interest in the disease. As elsewhere, the majority of cases have type 2 diabetes mellitus and occupational exposure to the environment. Most present with community-acquired pneumonia and/or bacteremia, especially during heavy rainfall. The high seropositivity rate (29%) in Karnataka and isolation of B. pseudomallei from the environment in Tamil Nadu and Kerala confirm India as melioidosis-endemic, although the full extent of the distribution of the organism across the country is unknown. There are limited molecular epidemiological data, but, thus far, the majority of Indian isolates have appeared distinct from those from South East Asia and Australia. Among other South Asian countries, Sri Lanka and Bangladesh are known to be melioidosis endemic, but there are no cases that have conclusively proved to have been acquired in Nepal, Bhutan, Afghanistan or Pakistan. There are no surveillance systems in place for melioidosis in South Asian countries. However, over the past two years, researchers at the Center for Emerging and Tropical Diseases of Kasturba Medical College, University of Manipal, have established the Indian Melioidosis Research Forum (IMRF), held the first South Asian Melioidosis Congress, and have been working to connect researchers, microbiologists and physicians in India and elsewhere in South Asia to raise awareness through training initiatives, the media, workshops, and conferences, with the hope that more patients with melioidosis will be diagnosed and treated appropriately. However, much more work needs to be done before we will know the true burden and distribution of melioidosis across South Asia. PMID- 30274449 TI - The Unique Life Cycle of Strongyloides stercoralis and Implications for Public Health Action. AB - Strongyloides stercoralis has one of the most complex life cycles of the human infecting nematodes. A common misconception in medical and public health professions is that S. stercoralis in its biology is akin to other intestinal nematodes, such as the hookworms. Despite original evidence provided by medical and veterinary research about this unique helminth, many assumptions have entered the scientific literature. This helminth is set apart from others that commonly affect humans by (a) the internal autoinfective cycle with autoinfective larvae randomly migrating through tissue, parthenogenesis, and the potential for lifelong infection in the host, the profound pathology occurring in hyperinfection and systemic manifestations of strongyloidiasis, and (b) a limited external cycle with a single generation of free-living adults. This paper aims to review and discuss original research on the unique life cycle of S. stercoralis that distinguishes it from other helminths and highlight areas where increased understanding of the parasite's biology might lead to improved public health prevention and control strategies.

AB - BACKGROUND: The diagnostic performance of the Kato Katz (KK) technique and the point-of-care circulating cathodic antigen (POC-CCA) test in detecting S. mansoni infection in the presence of the human immunodeficiency virus-1 (HIV-1) infection has remained inconclusive. The present cross-sectional survey compared the diagnostic performance of the KK technique and the POC-CCA test in diagnosing S. mansoni infection in an adult population co-infected with HIV-1 in northwestern Tanzania. METHODS: Single urine and stool samples from 979 adults were screened for S. mansoni infection using both the KK technique and POC-CCA tests. To compare the performance of the two diagnostic tests a combined artificial gold standard was created, based on either an egg-positive KK technique or a POC-CCA positive test. RESULTS: Based on the KK technique, the prevalence of S. mansoni was 47.3% (463/979, 95% CI: 44.2-50.4), as compared to 60.5% by the POC-CCA test (592/979; 95% CI: 57.4-63.5). The overall sensitivity and specificity of the POC CCA test were 92.5% (95% CI: 89.4-94.9) and 73.3% (95% CI: 69.6-76.8), respectively. In the HIV-1 seropositive group, the sensitivity and specificity of the POC-CCA test were 78.1% (95% CI: 60.0-90.7) and 45.9% (95% CI: 35.8-56.3). Using a combined gold standard, the sensitivity of the POC-CCA test increased to >90% in both subgroups whereas that of the KK technique in the HIV-1 seropositive group was low (49.5%; 95% CI: 39.6-59.5). CONCLUSION: In the presence of HIV-1 co infection, the KK technique attained a very low sensitivity. The POC-CCA test offers the best option for the rapid screening of S. mansoni infection in communities with a high prevalence of HIV-1 infection. PMID- 30274451 TI - The Convergence of High-Consequence Livestock and Human Pathogen Research and Development: A Paradox of Zoonotic Disease. AB - The World Health Organization (WHO) estimates that zoonotic diseases transmitted from animals to humans account for 75 percent of new and emerging infectious diseases. Globally, high-consequence pathogens that impact livestock and have the potential for human transmission create research paradoxes and operational challenges for the high-containment laboratories that conduct work with them. These specialized facilities are required for conducting all phases of research on high-consequence pathogens (basic, applied, and translational) with an emphasis on both the generation of fundamental knowledge and product development. To achieve this research mission, a highly-trained workforce is required and flexible operational methods are needed. In addition, working with certain pathogens requires compliance with regulations such as the Centers for Disease Control (CDC) and the U.S. Department of Agriculture (USDA) Select Agent regulations, which adds to the operational burden. The vast experience from the existing studies at Plum Island Animal Disease Center, other U.S. laboratories, and those in Europe and Australia with biosafety level 4 (BSL-4) facilities designed for large animals, clearly demonstrates the valuable contribution this capability brings to the efforts to detect, prepare, prevent and respond to livestock and potential zoonotic threats. To raise awareness of these challenges, which include biosafety and biosecurity issues, we held a workshop at the 2018 American Society for Microbiology (ASM) Biothreats conference to further discuss the topic with invited experts and audience participants. The workshop covered the subjects of research funding and metrics, economic sustainment of drug and vaccine development pipelines, workforce turnover, and the challenges of maintaining operational readiness of high containment laboratories. PMID- 30274452 TI - Potential Animal Reservoir of Mycobacterium ulcerans: A Systematic Review. AB - Mycobacterium ulcerans is the causative agent of Buruli ulcer, also known in Australia as Daintree ulcer or Bairnsdale ulcer. This destructive skin disease is characterized by extensive and painless necrosis of the skin and soft tissue with the formation of large ulcers, commonly on the leg or arm. To date, 33 countries with tropical, subtropical and temperate climates in Africa, the Americas, Asia and the Western Pacific have reported cases of Buruli ulcer. The disease is rarely fatal, although it may lead to permanent disability and/or disfigurement if not treated appropriately or in time. It is the third most common mycobacterial infection in the world after tuberculosis and leprosy. The precise mode of transmission of M. ulcerans is yet to be elucidated. Nevertheless, it is possible that the mode of transmission varies with different geographical areas and epidemiological settings. The knowledge about the possible routes of transmission and potential animal reservoirs of M. ulcerans is poorly understood and still remains patchy. Infectious diseases arise from the interaction of agent, host and environment. The majority of emerging or remerging infectious disease in human populations is spread by animals: either wildlife, livestock or pets. Animals may act as hosts or reservoirs and subsequently spread the organism to the environment or directly to the human population. The reservoirs may or may not be the direct source of infection for the hosts; however, they play a major role in maintenance of the organism in the environment, and in the mode of transmission. This remains valid for M. ulcerans. Possums have been suggested as one of the reservoir of M. ulcerans in south-eastern Australia, where possums ingest M. ulcerans from the environment, amplify them and shed the organism through their faeces. We conducted a systematic review with selected key words on PubMed and INFORMIT databases to aggregate available published data on animal reservoirs of M. ulcerans around the world. After certain inclusion and exclusion criteria were implemented, a total of 17 studies was included in the review. A variety of animals around the world e.g., rodents, shrews, possums (ringtail and brushtail), horses, dogs, alpacas, koalas and Indian flap-shelled turtles have been recorded as being infected with M. ulcerans. The majority of studies included in this review identified animal reservoirs as predisposing to the emergence and reemergence of M. ulcerans infection. Taken together, from the selected studies in this systematic review, it is clear that exotic wildlife and native mammals play a significant role as reservoirs for M. ulcerans. PMID- 30274453 TI - Mapping Disease Transmission Risk of Nipah Virus in South and Southeast Asia. AB - Since 1998, Nipah virus (NiV) (genus: Henipavirus; family: Paramyxoviridae), an often-fatal and highly virulent zoonotic pathogen, has caused sporadic outbreak events. Fruit bats from the genus Pteropus are the wildlife reservoirs and have a broad distribution throughout South and Southeast Asia, and East Africa. Understanding the disease biogeography of NiV is critical to comprehending the potential geographic distribution of this dangerous zoonosis. This study implemented the R packages ENMeval and BIOMOD2 as a means of modeling regional disease transmission risk and additionally measured niche similarity between the reservoir Pteropus and the ecological characteristics of outbreak localities with the Schoener's D index and I statistic. Results indicate a relatively high degree of niche overlap between models in geographic and environmental space (D statistic, 0.64; and I statistic, 0.89), and a potential geographic distribution encompassing 19% (2,963,178 km2) of South and Southeast Asia. This study should contribute to current and future efforts to understand the critical ecological contributors and geography of NiV. Furthermore, this study can be used as a geospatial guide to identify areas of high disease transmission risk and to inform national public health surveillance programs. PMID- 30274454 TI - The History of Bancroftian Lymphatic Filariasis in Australasia and Oceania: Is There a Threat of Re-Occurrence in Mainland Australia? AB - Lymphatic filariasis (LF) infects an estimated 120 million people worldwide, with a further 856 million considered at risk of infection and requiring preventative chemotherapy. The majority of LF infections are caused by Wuchereria bancrofti, named in honour of the Australian physician Joseph Bancroft, with the remainder due to Brugia malayi and B. timori. Infection with LF through the bite of an infected mosquito, can lead to the development of the condition known as elephantiasis, where swelling due to oedema leads to loss of function in the affected area and thickening of the skin, 'like an elephant'. LF has previously been endemic in Australia, although currently, no autochthonous cases occur there. Human immigration to Australia from LF-endemic countries, including those close to Australia, and the presence of susceptible mosquitoes that can act as suitable vectors, heighten the possibility of the reintroduction of LF into this country. In this review, we examine the history of LF in Australia and Oceania and weigh up the potential risk of its re-occurrence on mainland Australia. PMID- 30274455 TI - Scabies in Resource-Poor Communities in Nasarawa State, Nigeria: Epidemiology, Clinical Features and Factors Associated with Infestation. AB - Epidemiology and clinical features of scabies remain largely unknown in Nigeria's rural communities. To fill this gap, we performed a cross-sectional study in three rural communities in north central Nigeria. A total of 500 individuals were included and examined for scabies infestation; a questionnaire was applied to collect socio-demographic and behavioral data. Scabies was diagnosed in 325 (65.0%) participants. Excoriations (68.6%), vesicles (61.8%), and papules (58.8%) were common skin lesions. Itching was the most common symptom (77.5%); 64% complained of sleep disturbances. Lymphadenopathy was identified in 48.3%. Lesions were most commonly encountered on the abdomen (35.5%), inguinal area (19.1%), and interdigital spaces (14.2%). Poverty-related variables, such as illiteracy (OR: 7.15; 95% CI: 3.71-13.95), low household income (7.25; 1.19 88.59), absence of a solid floor inside house (12.17; 2.83-52.34), and overcrowding (1.98; 1.08-2.81) were significantly associated with infestation. Individual behavior, such as sharing of beds/pillows (2.11; 1.42-3.14) and sharing of clothes (2.51; 1.57-3.99), was also highly significantly associated with scabies. Regular bathing habits (0.37; 0.24-0.56) and regular use of bathing soap (0.36; 0.21-0.53) were protective factors. Scabies is extremely common in the communities under study and is associated with considerable morbidity. The disease is intrinsically linked with extreme poverty. PMID- 30274456 TI - Melioidosis in South America. AB - Melioidosis is an emerging disease in the Americas. This paper reviews confirmed cases, the presence of Burkholderia pseudomallei and the organization of national surveillance policies for melioidosis in South America. Confirmed cases in humans have been reported from Ecuador, Venezuela, Colombia, Brazil, and Peru. The bacterium has been isolated from the environment in Brazil and Peru. The state of Ceara, northeastern region of Brazil, is the only place where specific public strategies and policies for melioidosis have been developed. We also discuss the urgent need for health authorities in South America to pay greater attention to this disease, which has the potential to have a high impact on public health, and the importance of developing coordinated strategies amongst countries in this region. PMID- 30274457 TI - Argument for Inclusion of Strongyloidiasis in the Australian National Notifiable Disease List. AB - Strongyloidiasis is an infection caused by the helminth, Strongyloides stercoralis. Up to 370 million people are infected with the parasite globally, and it has remained endemic in the Indigenous Australian population for many decades. Strongyloidiasis has been also reported in other Australian populations. Ignorance of this disease has caused unnecessary costs to the government health system, and been detrimental to the Australian people's health. This manuscript addresses the 12 criteria required for a disease to be included in the Australian National Notifiable Disease List (NNDL) under the National Health Security Act 2007 (Commonwealth). There are six main arguments that provide compelling justification for strongyloidiasis to be made nationally notifiable and added to the Australian NNDL. These are: The disease is important to Indigenous health, and closing the health inequity gap between Indigenous and non-Indigenous Australians is a priority; a public health response is required to detect cases of strongyloidiasis and to establish the true incidence and prevalence of the disease; there is no alternative national surveillance system to gather data on the disease; there are preventive measures with high efficacy and low side effects; data collection is feasible as cases are definable by microscopy, PCR, or serological diagnostics; and achievement of the Sustainable Development Goal (SDG) # 6 on clean water and sanitation. PMID- 30274460 TI - Paediatric Strongyloidiasis in Central Australia. AB - Few published studies are available describing the prevalence of paediatric strongyloidiasis in endemic areas within Australia. This literature review and exploratory clinical audit presents the first seroprevalence data for paediatric patients in Central Australia. A total of 16.1% (30/186) of paediatric inpatients tested for Strongyloides stercoralis in 2016 were seropositive (95% CI: 11.5% to 22.1%). Eosinophilia of unknown aetiology was the most common indication for testing (91.9%). Seropositive patients were significantly more likely to reside in communities outside of Alice Springs (p = 0.02). Seropositive patients were noted to have higher mean eosinophil counts with a mean difference of 0.86 * 108/L (95% CI: 0.56 to 1.16, p < 0.0001), although the limited utility of eosinophilia as a surrogate marker of strongyloidiasis has been described previously. All seropositive patients were Indigenous. There was no significant difference in ages between groups. There was a male predominance in the seropositive group, although this was not significant (p = 0.12). Twelve patients had known human T-lymphotropic virus 1 (HTLV-1) status and all were seronegative. Further research describing the epidemiology of strongyloidiasis in Central Australia is required. PMID- 30274459 TI - Outer Membrane Protein A Conservation among Orientia tsutsugamushi Isolates Suggests Its Potential as a Protective Antigen and Diagnostic Target. AB - Scrub typhus threatens one billion people in the Asia-Pacific area and cases have emerged outside this region. It is caused by infection with any of the multitude of strains of the bacterium Orientia tsutsugamushi. A vaccine that affords heterologous protection and a commercially-available molecular diagnostic assay are lacking. Herein, we determined that the nucleotide and translated amino acid sequences of outer membrane protein A (OmpA) are highly conserved among 51 O. tsutsugamushi isolates. Molecular modeling revealed the predicted tertiary structure of O. tsutsugamushi OmpA to be very similar to that of the phylogenetically-related pathogen, Anaplasma phagocytophilum, including the location of a helix that contains residues functionally essential for A. phagocytophilum infection. PCR primers were developed that amplified ompA DNA from all O. tsutsugamushi strains, but not from negative control bacteria. Using these primers in quantitative PCR enabled sensitive detection and quantitation of O. tsutsugamushi ompA DNA from organs and blood of mice that had been experimentally infected with the Karp or Gilliam strains. The high degree of OmpA conservation among O. tsutsugamushi strains evidences its potential to serve as a molecular diagnostic target and justifies its consideration as a candidate for developing a broadly-protective scrub typhus vaccine. PMID- 30274458 TI - Melioidosis in Africa: Time to Uncover the True Disease Load. AB - Melioidosis is an often fatal infectious disease with a protean clinical spectrum, caused by the environmental bacterial pathogen Burkholderia pseudomallei. Although the disease has been reported from some African countries in the past, the present epidemiology of melioidosis in Africa is almost entirely unknown. Therefore, the common view that melioidosis is rare in Africa is not evidence-based. A recent study concludes that large parts of Africa are environmentally suitable for B. pseudomallei. Twenty-four African countries and three countries in the Middle East were predicted to be endemic, but no cases of melioidosis have been reported yet. In this study, we summarize the present fragmentary knowledge on human and animal melioidosis and environmental B. pseudomallei in Africa and the Middle East. We propose that systematic serological studies in man and animals together with environmental investigations on potential B. pseudomallei habitats are needed to identify risk areas for melioidosis. This information can subsequently be used to target raising clinical awareness and the implementation of simple laboratory algorithms for the isolation of B. pseudomallei from clinical specimens. B. pseudomallei was most likely transferred from Asia to the Americas via Africa, which is shown by phylogenetic analyses. More data on the virulence and genomic characteristics of African B. pseudomallei isolates will contribute to a better understanding of the global evolution of the pathogen and will also help to assess potential differences in disease prevalence and outcome. PMID- 30274462 TI - Translational Venomics: Third-Generation Antivenomics of Anti-Siamese Russell's Viper, Daboia siamensis, Antivenom Manufactured in Taiwan CDC's Vaccine Center. AB - The venom proteome of Siamese Russell's viper from Taiwan, alongside complementary in vivo lethality neutralization assay and in vitro third generation antivenomics assessment of the preclinical efficacy of the homologous antivenom manufactured in Taiwan CDC's Vaccine Center, are here reported. Taiwanese Russell's viper venom proteome comprised 25 distinct gene products, with the heterodimeric PLA2 viperotoxin-F representing the most abundant toxin (47.5% of total venom proteome). Coagulation FV-activating serine proteinase (RVV V, 14%), the PIV-SVMP activator of FX (RVV-FX, 8.5%), and less abundant toxins from nine protein families, make up its venom proteome. Venom composition pathology correlations of D. siamensis envenomings in Taiwan are discussed. The lethal effect of Taiwanese D. siamensis venom was 0.47 mg/g mouse. Antivenomics guided assessment of the toxin recognition landscape of the Taiwanese Russell's viper antivenom, in conjunction with complementary in vivo neutralization analysis, informed the antivenom's maximal toxin immunorecognition ability (14 mg total venom proteins/vial), neutralization capacity (6.5 mg venom/vial), and relative content of lethality neutralizing antibodies (46.5% of the toxin-binding F(ab')2 antibodies). The antivenomics analysis also revealed suboptimal aspects of the CDC-Taiwan antivenom. Strategies to improve them are suggested. PMID- 30274461 TI - An Overview of Brucellosis in Cattle and Humans, and its Serological and Molecular Diagnosis in Control Strategies. AB - Brucellosis is one of the most common contagious and communicable zoonotic diseases with high rates of morbidity and lifetime sterility. There has been a momentous increase over the recent years in intra/interspecific infection rates, due to poor management and limited resources, especially in developing countries. Abortion in the last trimester is a predominant sign, followed by reduced milk yield and high temperature in cattle, while in humans it is characterized by undulant fever, general malaise, and arthritis. While the clinical picture of brucellosis in humans and cattle is not clear and often misleading with the classical serological diagnosis, efforts have been made to overcome the limitations of current serological assays through the development of PCR-based diagnosis. Due to its complex nature, brucellosis remains a serious threat to public health and livestock in developing countries. In this review, we summarized the recent literature, significant advancements, and challenges in the treatment and vaccination against brucellosis, with a special focus on developing countries. PMID- 30274463 TI - The Importance of Water Typologies in Lay Entomologies of Aedes aegypti Habitat, Breeding and Dengue Risk: A Study from Northern Australia. AB - Dengue fever is making a significant comeback globally and its control still depends largely on residents' actions. Community awareness and education are central to its management; however, programmes have had limited impact, because they are often based on short-term research and limited awareness of the socio ecological contexts wherein local knowledge of dengue and its vectors (lay entomology) is produced and enacted in and through place. Long-term studies of lay knowledge of dengue vectors are very rare, even though they are essential to the development of effective, targeted community education campaigns and mobilisation. In this paper, we examine the popular belief that dengue vector, Aedes aegypti, is ubiquitous in the north Australian landscape and demonstrate how local typologies of water are central to the reasoning underwriting this assumption. We show how these logics are fortified by people's lived experiences of mosquitoes and the watery abodes they are thought to reside in, as well as through key messages from health education. We posit that long term, context sensitive research approaches are better able to identify, understand and later address and challenge assumptions and may be more effective at informing, empowering and mobilizing the public to combat dengue fever. PMID- 30274464 TI - Schistosome Vaccines for Domestic Animals. AB - Schistosomiasis is recognized as a tropical disease of considerable public health importance, but domestic livestock infections due to Schistosoma japonicum, S. bovis, S. mattheei and S. curassoni are often overlooked causes of significant animal morbidity and mortality in Asia and Africa. In addition, whereas schistosomiasis japonica is recognized as an important zoonosis in China and the Philippines, reports of viable schistosome hybrids between animal livestock species and S. haematobium point to an underappreciated zoonotic component of transmission in Africa as well. Anti-schistosome vaccines for animal use have long been advocated as part of the solution to schistosomiasis control, benefitting humans and animals and improving the local economy, features aligning with the One Health concept synergizing human and animal health. We review the history of animal vaccines for schistosomiasis from the early days of irradiated larvae and then consider the recombinant DNA technology revolution and its impact in developing schistosome vaccines that followed. We evaluate the major candidates tested in livestock, including the glutathione S-transferases, paramyosin and triose-phosphate isomerase, and summarize some of the future challenges that need to be overcome to design and deliver effective anti schistosome vaccines that will complement current control options to achieve and sustain future elimination goals.

PMID- 30274465 TI - A Rapid Appraisal of Factors Influencing Praziquantel Treatment Compliance in Two Communities Endemic for Schistosomiasis in Cote d'Ivoire. AB - Over the past decade, a significant reduction in the prevalence of schistosomiasis has been achieved, partially explained by the large-scale administration of praziquantel. Yet, the burden of schistosomiasis remains considerable, and factors influencing intervention coverage are important. This study aimed to deepen the understanding of low treatment coverage rates observed in two schistosomiasis-endemic villages in Cote d'Ivoire. The research was conducted in August 2015, in Moronou and Bigouin, two villages of Cote d'Ivoire that are endemic for Schistosoma haematobium and S. mansoni, respectively. After completion of a clinical trial, standard praziquantel treatment (single 40 mg/kg oral dose) was offered to all village inhabitants by community health workers using a house-to-house approach. Factors influencing treatment coverage were determined by a questionnaire survey, randomly selecting 405 individuals. The overall treatment coverage rate was only 47.6% (2730/5733) with considerable intervillage heterogeneity (27.7% in Bigouin (302/1091) versus 52.3% in Moronou (2428/4642)). Among the 200 individuals interviewed in Moronou, 50.0% were administered praziquantel, while only 19.5% of the 205 individuals interviewed in Bigouin received praziquantel. The main reasons for low treatment coverage were work-related (agricultural activities), the bitter taste of praziquantel and previous experiences with adverse events. The most suitable period for treatment campaigns was reported to be the dry season. More than three-quarter of the interviewees who had taken praziquantel (overall, 116/140; Moronou, 84/100; Bigouin, 32/40) declared that they would not participate in future treatments (p < 0.001). In order to enhance praziquantel treatment coverage, careful consideration should be given to attitudes and practices, such as prior or perceived adverse events and taste of praziquantel, and appropriate timing, harmonized with agricultural activities. Without such understanding, breaking the transmission of schistosomiasis remains a distant goal. PMID- 30274467 TI - From Incriminating Stegomyia fasciata to Releasing Wolbachia pipientis: Australian Research on the Dengue Virus Vector, Aedes aegypti, and Development of Novel Strategies for Its Surveillance and Control. AB - Globally, the dengue viruses (DENVs) infect approximately 300 million people annually. Australia has a history of epidemic dengue, with outbreaks in the early decades of the twentieth century responsible for tens of thousands of cases. Seminal experiments conducted by Australian scientists during these outbreaks were the first to incriminate Aedes aegypti as a major vector of dengue viruses. One hundred years later, Australian scientists are playing a lead role in the development of surveillance and suppression strategies that target this mosquito species. Surveillance of Ae. aegypti populations and their associated dengue risk was greatly improved by understanding the contribution of key premises, key containers, and cryptic larval habitats to mosquito productivity, and, more recently, the development of novel adult traps. In terms of mosquito control, targeted indoor residual pyrethroid spraying and community-based biological control utilizing predatory copepods can significantly reduce Ae. aegypti populations. The release of Ae. aegypti transinfected with the virus-blocking bacterium, Wolbachia, provides a promising strategy for limiting DENV transmission. These diverse strategies developed by Australian scientists have the potential to alleviate the burden of dengue in the future, whether it is at the local level or as part of a country-wide program. PMID- 30274468 TI - Coverage, Timelines, and Determinants of Incomplete Immunization in Bangladesh. AB - : Immunization has become one of the major contributors to public health globally as it prevents communicable disease, particularly in children. The objective of this study was to estimate the extent of timely immunization coverage and to investigate the determinants of incomplete and untimely vaccination. METHODS: The study used data from the latest Bangladesh Demographic Health Survey (BDHS) 2014. A total sample of 1631 children aged 12-23 months who had an Expanded Program on Immunization (EPI) card and immunization history were analyzed. Multivariable logistic regression models were used to determine the significant influencing factors on untimely vaccination (BCG, pentavalent vaccine/OPV, and measles) and incomplete vaccination. The results were presented in terms of adjusted odds ratio (AOR) with a 95% confidence interval and a significance level p < 0.05. RESULTS: The proportions of children who received timely vaccinations were 24% for BCG, 46% for pentavalent 3, and 53% for measles, whereas 76%, 51%, and 36% children failed to receive the BCG, pentavalent 3, and measles vaccines, respectively, in a timely manner. The proportion of early vaccination was 3% for pentavalent 3 and 12% for measles. Several significant influencing factors including age, maternal education and working status, awareness of community clinics, socioeconomic status, and geographic variation significantly contributed to untimely and incomplete vaccination of children in Bangladesh. CONCLUSIONS: The study identified some key determinants of untimely and incomplete childhood vaccinations in the context of Bangladesh. The findings will contribute to the improvement of age-specific vaccination and support policy makers in taking the necessary control strategies with respect to delayed and early vaccination in Bangladesh. PMID- 30274470 TI - Serological Cross-Reactivity among Orientia tsutsugamushi Serotypes but Not with Rickettsia japonica in Japan. AB - The rickettsial diseases Japanese spotted fever (JSF) and scrub typhus (ST) are caused by Rickettsia japonica and Orientia tsutsugamushi, respectively. The diseases share clinical symptoms, such as fever, rash, and eschar. However, there are no systematical investigations of the serological cross-reactivity between R. japonica and O. tsutsugamushi. Also, the serological cross-reactivity among O. tsutsugamushi serotypes is still unclear. We analyzed 1406 cases tested by indirect immunoperoxidase assay using seven rickettsial antigens-one R. japonica and six O. tsutsugamushi serotypes-between 2003 and 2016 at two reference centers in Japan. Of these, 167 JSF and 190 ST cases were serologically diagnosed. None of the ST cases had a significant increase in IgM titers against R. japonica. Six JSF cases showed IgG titers of >=40 against O. tsutsugamushi, but no IgG titer showed a significant elevation in the convalescent phase sample. We observed a substantial degree of cross-reactivity between O. tsutsugamushi serotypes. Cross reactivity was significant among Karp, Hirano/Kuroki, and Kato types and between Gilliam and Irie/Kawasaki types in IgM, while the Shimokoshi type was less cross reactive than the others. In conclusion, there is no serological cross-reaction between R. japonica and O. tsutsugamushi. The cross-reactivity among O.tsutsugamushi varies depending on serotypes. PMID- 30274469 TI - A 12-Year Retrospective Study of Invasive Amoebiasis in Western Sydney: Evidence of Local Acquisition. AB - In Australia, amoebiasis is thought to occur in travellers, immigrants from endemic areas, and among men who have sex with men. Prevalence of amoebiasis in communities with immigrants from Entamoeba histolytica-endemic countries is unknown. The present study is a retrospective case series analysis of patients with laboratory-confirmed amoebiasis from Western Sydney Local Health District, Australia, between years 2005 and 2016. Forty-nine patients with amoebiasis were identified, resulting in an estimated annual incidence of up to 1.1 cases per 100,000 adults. Many were born in Australia (15/47) and India (12/47). Three patients (3/37) had no history of overseas travel, two others had not travelled to an endemic country, and an additional two had a very remote history of overseas travel; one died of fulminant amoebic colitis. Three patients (3/16) were employed in the food industry and one had a history of colonic irrigation in an Australian 'wellness clinic'. Patients had invasive amoebiasis with either liver abscess (41/48) or colitis (7/48), diagnosed most commonly by serology. Invasive procedures were common, including aspiration of liver abscess (28/41), colonoscopy (11/49), and partial hepatectomy (1/49). Although rare, local acquisition of amoebiasis occurs in Western Sydney and contributes to significant morbidity and hospital admissions. PMID- 30274471 TI - On the Home Front: Specialised Reference Testing for Dengue in the Australasian Region. AB - Reference laboratories are vital for disease control and interpreting the complexities and impact of emerging pathogens. The role of these centralized facilities extends beyond routine screening capabilities to provide rapid, specific, and accurate diagnoses, advanced data analysis, consultation services, and sophisticated disease surveillance and monitoring. Within the Australasian region, the Public Health Virology Laboratory (PHV), Forensic and Scientific Services, Department of Health, Queensland Government, Australia, and the Institute of Environmental Science and Research Limited (ESR), New Zealand (NZ) perform specialised reference testing and surveillance for dengue viruses (DENVs) and other emerging arthropod-borne viruses (arboviruses), including chikungunya virus (CHIKV) and Zika virus (ZIKV). With a focus on DENV, we review the reference testing performed by PHV (2005 to 2017) and ESR (2008 to 2017). We also describe how the evolution and expansion of reference-based methodologies and the adoption of new technologies have provided the critical elements of preparedness and early detection that complement frontline public health control efforts and limit the spread of arboviruses within Australasia.

AB - Due to conservation and rehabilitation efforts, mangrove forests represent some of the largest environmental niches in Malaysia. However, there is little information on the potential risks posed by mosquitoes that are directly and indirectly associated with mangrove forests. To study the potential health risk to humans active within and in close vicinity of mangrove forests, this research focused on the day biting habits of mosquitoes in mangrove forests of Kedah, Malaysia. The bare leg catch (BLC) method was used to collect adult mosquitoes during a 12-h period from 7:30 a.m. to 7:30 p.m. in both disturbed and less disturbed areas of mangroves. In total, 795 adult mosquitoes from 5 genera and 8 species were collected, and over 65% of the total mosquitoes were collected from the less disturbed area. The predominant species from the less disturbed area was Verrallina butleri; in the disturbed area the dominant species was Culex sitiens. The peak biting hour differed for each species, with Aedes albopictus and Cx. sitiens recorded as having a bimodal biting activity peak during dawn and dusk. For Ve. butleri an erratic pattern of biting activity was recorded in the less disturbed area but it peaked during the early daytime for both collection points. Overall, the distinct pattern of day biting habits of mosquitoes within mangroves peaked during dawn and dusk for the less disturbed area but was irregular for the disturbed area throughout the day. The presence of vectors of pathogens such as Ae. albopictus for both areas raises the need for authorities to consider management of mosquitoes in mangrove forests. PMID- 30274472 TI - Exotic Parasite Threats to Australia's Biosecurity-Trade, Health, and Conservation. AB - Parasites have threatened Australia's biosecurity since the early days of European settlement. Tick fever in cattle and liver fluke, along with their invertebrate hosts, and hydatid disease head the list of parasites that are still impacting livestock industries. In addition, there are many parasites that have been introduced that are of significance to public health as well as the conservation of native wildlife. As a consequence of these early arrivals, Australia has become much more aware of its vulnerability should parasites such as Trichinella and Trypanosoma evansi become established in Australia. However, recent discoveries concerning Leishmania and other trypanosomes have demonstrated that Australia must not become complacent and reliant on dogma when considering the potential emergence of new threats to its biosecurity. In this short review, the major parasite threats to Australia's biosecurity are summarised, some misconceptions are emphasised, and attention is given to the importance of challenging dogma in the face of a dearth of information about Australian native fauna. PMID- 30274475 TI - Epidemiology and Spatiotemporal Patterns of Leprosy Detection in the State of Bahia, Brazilian Northeast Region, 2001-2014. AB - The detection of leprosy cases is distributed unequally in Brazil, with high-risk clusters mainly in the North and Northeast regions. Knowledge on epidemiology and spatiotemporal patterns of leprosy occurrence and late diagnosis in these areas is critical to improve control measures. We performed a study including all leprosy cases notified in the 417 municipalities of Bahia state, from 2001 to 2014. New case detection (overall and pediatric <15 years) and grade 2 disability (G2D) rates were calculated and stratified according to socio-demographic variables. Spatial analyses were performed to detect high-risk areas for occurrence and late diagnosis. A total of 40,060 new leprosy cases was reported in the period (mean = 2861 cases/year), 3296 (8.2%) in <15-year-olds, and 1921 (4.8%) with G2D. The new case detection rate was 20.41 cases/100,000 inhabitants (95% CI: 19.68-21.17). A higher risk was identified in older age groups (RR = 8.45, 95% CI: 7.08-10.09) and in residents living in the state capital (RR = 5.30, 95% CI: 4.13-6.79), in medium-sized cities (RR = 2.80; 95% CI: 2.50-3.13), and in the west (RR = 6.56, 95% CI: 5.13-8.39) and far south regions of the state (RR = 6.56, 95% CI: 5.13-8.39). A higher risk of G2D was associated with male gender (RR = 2.43, 95% CI: 2.20-2.67), older age (RR = 44.08, 95% CI: 33.21 58.51), Afro-Brazilian ethnicity (RR = 1.59; 95% CI: 1.37-1.85), living in medium sized cities (RR = 2.60; 95% CI: 2.27-2.96) and residency in the north (RR = 5.02; 95% CI: 3.74-6.73) and far south (RR = 7.46; 95% CI: 5.58-9.98) regions. Heterogeneous space-time patterns of leprosy distribution were identified, indicating high endemicity, recent transmission, and late diagnosis. This heterogeneous distribution of the disease was observed throughout the study period. Leprosy remains a relevant public health problem in Bahia state. The disease has a focal distribution. We reinforce the importance of integrating surveillance, prevention and control actions in regions of higher risk of leprosy detection and late diagnosis, and in the most vulnerable populations. PMID- 30274474 TI - Differential Susceptibility of Male Versus Female Laboratory Mice to Anaplasma phagocytophilum Infection. AB - Human granulocytic anaplasmosis (HGA) is a debilitating, non-specific febrile illness caused by the granulocytotropic obligate intracellular bacterium called Anaplasma phagocytophilum. Surveillance studies indicate a higher prevalence of HGA in male versus female patients. Whether this discrepancy correlates with differential susceptibility of males and females to A. phagocytophilum infection is unknown. Laboratory mice have long been used to study granulocytic anaplasmosis. Yet, sex as a biological variable (SABV) in this model has not been evaluated. In this paper, groups of male and female C57Bl/6 mice that had been infected with A. phagocytophilum were assessed for the bacterial DNA load in the peripheral blood, the percentage of neutrophils harboring bacterial inclusions called morulae, and splenomegaly. Infected male mice exhibited as much as a 1.85 fold increase in the number of infected neutrophils, which is up to a 1.88-fold increase in the A. phagocytophilum DNA load, and a significant increase in spleen size when compared to infected female mice. The propensity of male mice to develop a higher level of A. phagocytophilum infection is relevant for studies utilizing the mouse model. This stresses the importance of including SABV and aligns with the observed higher incidence of infection in male versus female patients. PMID- 30274476 TI - New Immuno-Epidemiological Biomarker of Human Exposure to Aedes Vector Bites: From Concept to Applications. AB - Arthropod-borne viruses (arboviruses) such as dengue virus (DENV), chikungunya virus (CHIKV), Zika virus (ZIKV), and yellow fever virus (YFV) are the most important 'emerging pathogens' because of their geographic spread and their increasing impact on vulnerable human populations. To fight against these arboviruses, vector control strategies (VCS) remain one of the most valuable means. However, their implementation and monitoring are labour intensive and difficult to sustain on large scales, especially when transmission and Aedes mosquito densities are low. To increase the efficacy of VCS, current entomological methods should be improved by new complementary tools which measure the risk of arthropod-borne diseases' transmission. The study of human-Aedes immunological relationships can provide new promising serological tools, namely antibody-based biomarkers, allowing to accurately estimate the human-Aedes contact and consequently, the risk of transmission of arboviruses and the effectiveness of VCS. This review focuses on studies highlighting the concept, techniques, and methods used to develop and validate specific candidate biomarkers of human exposure to Aedes bites. Potential applications of such antibody-based biomarkers of exposure to Aedes vector bites in the field of operational research are also discussed. PMID- 30274478 TI - Cushing Syndrome due to Inappropriate Corticosteroid Topical Treatment of Undiagnosed Scabies. AB - The uncontrolled sale of topical corticosteroids has become an important risk factor for the development of iatrogenic Cushing syndrome in children, especially in countries where medications are sold over the counter. This is exacerbated by the lack of information for both the patients and pharmacists. This report documents a series of eight cases of iatrogenic Cushing syndrome secondary to an inappropriate use of topical steroids, due to a misdiagnosis of scabies. PMID- 30274479 TI - Risk Mapping of Visceral Leishmaniasis: A Spatial Regression Model for Attica Region, Greece. AB - Visceral Leishmaniasis (VL) is endemic to the Attica region of Greece. The geographical distribution of VL cases was analyzed employing methods of spatial analysis in a GIS environment. A geographic database was constructed including data for the disease cases and environmental factors, such as land cover types, stray dog population, and socioeconomic factors. Classic and spatial regression models are presented that suggest the factors contributing most to the incidence of leishmaniasis are green urban areas and the population of stray dogs in the municipalities of Attica region. The results of the spatial regression model were more accurate, thus were used to produce a disease risk map. This map indicates the high-risk municipalities in which surveillance for the control of leishmaniasis is necessary. PMID- 30274477 TI - DNA Diagnostics for Schistosomiasis Control. AB - Despite extensive efforts over the last few decades, the global disease burden of schistosomiasis still remains unacceptably high. This could partly be attributed to the lack of accurate diagnostic tools for detecting human and animal schistosome infections in endemic areas. In low transmission and low prevalence areas where schistosomiasis elimination is targeted, case detection requires a test that is highly sensitive. Diagnostic tests with low sensitivity will miss individuals with low infection intensity and these will continue to contribute to transmission, thereby interfering with the efficacy of the control measures operating. Of the many diagnostic approaches undertaken to date, the detection of schistosome DNA using DNA amplification techniques including polymerase chain reaction (PCR) provide valuable adjuncts to more conventional microscopic and serological methods, due their accuracy, high sensitivity, and the capacity to detect early pre-patent infections. Furthermore, DNA-based methods represent important screening tools, particularly in those endemic areas with ongoing control where infection prevalence and intensity have been reduced to very low levels. Here we review the role of DNA diagnostics in the path towards the control and elimination of schistosomiasis. PMID- 30274480 TI - Long-Range Diagnosis of and Support for Skin Conditions in Field Settings. AB - Skin diseases are a significant cause of morbidity and mortality worldwide; however, access to dermatology services are critically limited, particularly in low- to middle-income countries (LMIC), where there is an overall shortage of physicians. Implementation of long-range technological support tools has been growing in an effort to provide quality dermatology care to even the most remote settings globally. eHealth strategies can provide realistic healthcare solutions if implemented in a feasible and sensitive way, customizing tools to address the unique needs and resource limitations of the local setting. This article summarizes the various types of telemedicine and mobile health (mHealth) tools and their practical applications and benefits for patient care. The challenges and barriers of teledermatology are discussed, as well as steps to consider when implementing a new teledermatology initiative. eHealth arguably offers one of the most flexible and realistic tools for providing critically needed access to dermatology skills in underserved LMICs. PMID- 30274481 TI - When Should the Emphasis on Schistosomiasis Control Move to Elimination? AB - The stated goal of the World Health Organization's program on schistosomiasis is paraphrased as follows: to control morbidity and eliminate transmission where feasible. Switching from a goal of controlling morbidity to interrupting transmission may well be currently feasible in some countries in the Caribbean, some areas in South America, northern Africa, and selected endemic areas in sub Saharan Africa where there have been improvements in sanitation and access to clean water. However, in most of sub-Saharan Africa, where programmatic interventions still consist solely of annual mass drug administration, such a switch in strategies remains premature. There is a continued need for operational research on how best to reduce transmission to a point where interruption of transmission may be achievable. The level of infection at which it is feasible to transition from control to elimination must also be defined. In parallel, there is also a need to develop and evaluate approaches for achieving and validating elimination. There are currently neither evidence-based methods nor tools for breaking transmission or verifying that it has been accomplished. The basis for these statements stems from numerous studies that will be reviewed and summarized in this article; many, but not all of which were undertaken as part of SCORE, the Schistosomiasis Consortium for Operational Research and Evaluation. PMID- 30274482 TI - Treading the Path towards Genetic Control of Snail Resistance to Schistosome Infection. AB - Schistosomiasis remains the most important tropical snail-borne trematodiasis that threatens many millions of human lives. In achieving schistosomiasis elimination targets, sustainable control of the snail vectors represents a logical approach. Nonetheless, the ineffectiveness of the present snail control interventions emphasizes the need to develop new complementary strategies to ensure more effective control outcomes. Accordingly, the use of genetic techniques aimed at driving resistance traits into natural vector populations has been put forward as a promising tool for integrated snail control. Leveraging the Biomphalaria-Schistosoma model system, studies unraveling the complexities of the vector biology and those exploring the molecular basis of snail resistance to schistosome infection have been expanding in various breadths, generating many significant discoveries, and raising the hope for future breakthroughs. This review provides a compendium of relevant findings, and without neglecting the current existing gaps and potential future challenges, discusses how a transgenic snail approach may be adapted and harnessed to control human schistosomiasis. PMID- 30274483 TI - Community Involvement in the Care of Persons Affected by Podoconiosis-A Lesson for Other Skin NTDs. AB - Podoconiosis is a neglected tropical disease (NTD) characterized by lower-leg swelling (lymphedema), which is caused by long-term exposure to irritant red-clay soils found within tropical volcanic high-altitude environments with heavy rainfall. The condition places a substantial burden on affected people, their families and communities, including disability, economic consequences, social exclusion, and stigma; mental disorders and distress are also common. This paper focuses on community-based care of podoconiosis, and, in particular, the role that community involvement can have in the reduction of stigma against people affected by podoconiosis. We first draw on research conducted in Ethiopia for this, which has included community-based provision of care and treatment, education, and awareness-raising, and socioeconomic rehabilitation to reduce stigma. Since people affected by podoconiosis and other skin NTDs often suffer the double burden of mental-health illness, which is similarly stigmatized, we then point to examples from the mental-health field in low-resource community settings to suggest avenues for stigma reduction and increased patient engagement that may be relevant across a range of skin NTDs, though further research is needed on this. PMID- 30274484 TI - A Teledermatology Pilot Programme for the Management of Skin Diseases in Primary Health Care Centres: Experiences from a Resource-Limited Country (Mali, West Africa). AB - In sub-Saharan Africa, in particular in rural areas, patients have limited access to doctors with specialist skills in skin diseases. To address this issue, a teledermatology pilot programme focused on primary health centres was set up in Mali. This study was aimed at investigating the feasibility of this programme and its impact on the management of skin diseases. The programme was based on the store-and-forward model. Health care providers from 10 primary centres were trained to manage common skin diseases, to capture images of skin lesions, and to use an e-platform to post all cases beyond their expertise for dermatologists in order to obtain diagnosis and treatment recommendations. After training, the cases of 180 patients were posted by trained health workers on the platform. Ninety-six per cent of these patients were properly managed via the responses given by dermatologists. The mean time to receive the expert's response was 32 h (range: 13 min to 20 days). Analysis of all diseases diagnosed via the platform revealed a wide range of skin disorders. Our initiative hugely improved the management of all skin diseases in the targeted health centres. In developing countries, Internet accessibility and connection quality represent the main challenges when conducting teledermatology programmes. PMID- 30274486 TI - First Case Report of a Near Lethal Envenomation by a Salomonelaps par (Solomons Coral Snake) in the Solomon Islands. AB - Venomous snake bites in the Solomon Islands can be very dangerous due to lack of access to health care. There are no documented case reports of envenomation by snake bites in the Solomon Islands. This case report highlights the management of a patient with potentially lethal neurotoxicity secondary to a Solomonelaps par (Solomons coral snake) in a low resource setting. This case identifies the potential benefit of further research to determine the incidence of lethal envenomation as well as analysing the venom to determine if any commercially available antivenom would be useful in the treatment of envenomation by Salomonelaps par and other venomous snakes. There should be consideration given to providing education on first aid for people living in remote areas as well as education for health workers. PMID- 30274485 TI - Rabies in the Caribbean: A Situational Analysis and Historic Review. AB - Rabies virus is the only Lyssavirus species found in the Americas. In discussions about rabies, Latin America and the Caribbean are often grouped together. Our study aimed to independently analyse the rabies situation in the Caribbean and examine changes in rabies spatiotemporal epidemiology. A questionnaire was administered to the 33 member countries and territories of the Caribbean Animal Health Network (CaribVET) to collect current data, which was collated with a literature review. Rabies was endemic in ten Caribbean localities, with the dog, mongoose, and vampire bat identified as enzootic reservoirs. The majority of animal cases occurred in Puerto Rico, the Dominican Republic, and Haiti, while human cases only consistently occurred in the latter two areas. Rabies vaccination was conducted for high-risk animal populations with variable coverage, and rabies diagnostic capacities varied widely throughout the region. Illegal importation and natural migration of animals may facilitate the introduction of rabies virus variants into virus-naive areas. Passive surveillance, together with enhanced methods and serological screening techniques, can therefore be of value. The insularity of the Caribbean makes it ideal for conducting pilot studies on reservoir host population management. Best practice guidelines developed for these reservoir hosts can be individually modified to the epidemiological status and available resources within each locality. PMID- 30274487 TI - Melioidosis in Hong Kong. AB - Melioidosis, although endemic in many parts of Southeast Asia, has not been systematically studied in Hong Kong, which is a predominantly urban area located in the subtropics. This review describes the early outbreaks of melioidosis in captive animals in Hong Kong in the 1970s, as well as the early reports of human clinical cases in the 1980s. A review of all hospitalized human cases of culture confirmed melioidosis in the last twenty years showed an increasing trend in the incidence of the disease, with significant mortality observed. The lack of awareness of this disease among local physicians, the delay in laboratory diagnosis and the lack of epidemiological surveillance are among the greatest challenges of managing melioidosis in the territory. PMID- 30274488 TI - Advances in the Treatment of Yaws. AB - Yaws is one of the three endemic treponematoses and is recognised by the World Health Organization as a neglected tropical disease. Yaws is currently reported in 15 countries in the Pacific, South-East Asia, West and Central Africa, predominantly affects children, and results in destructive lesions of the skin and soft tissues. For most of the twentieth century penicillin-based treatment was the standard of care and resistance to penicillin has still not been described. Recently, oral azithromycin has been shown to be an effective treatment for yaws, facilitating renewed yaws eradication efforts. Resistance to azithromycin is an emerging threat and close surveillance will be required as yaws eradication efforts are scaled up globally. PMID- 30274489 TI - 'Know Your Epidemic': Are Prisons a Potential Barrier to TB Elimination in an Australian Context? AB - Globally, rates of tuberculosis (TB) cases in prisons are substantially higher than in the general population. The goal of this study was to review TB notifications in Victorian correctional facilities, and consider whether additional interventions towards TB elimination may be useful in this setting. All patients who were notified with or treated for TB in the Australian state of Victoria from 1 January 2003 to 1 December 2017 were included in this study. Descriptive analysis was performed. Demographic and treatment outcome data for individuals with and without a history of incarceration were reviewed and compared. Of the 5645 TB cases notified during the study period, 26 (0.5%) had a history of being incarcerated in correctional facilities while receiving treatment for TB. There were 73,238 inmates in Victorian correctional facilities over the same study period, meaning that approximately 0.04% of inmates were diagnosed or treated with TB disease in correctional facilities. Incarcerated individuals were more likely to have positive sputum smears and cavitation compared with nonincarcerated people with TB. There was no significant difference in treatment outcomes between the general TB population and those who had a history of incarceration during their treatment. There is a low apparent rate of TB in Victorian prisoners, and prisons do not contribute significantly to TB incidence in Victoria. Overall, TB outcomes do not differ between prisoners and nonprisoners. Ongoing efforts to sustain these lower rates and comparable outcomes in this vulnerable cohort are important for continued progress towards TB elimination. PMID- 30274492 TI - Acute Poisonings at a Regional Referral Hospital in Western Kenya. AB - The emergency department (ED) of the Jaramogi Oginga Odinga Teaching and Referral Hospital (JOOTRH) handles many cases of poisoning. However, there is scant information on the factors, agents, and outcomes of poisoning at the hospital. The aim of this work was to determine the factors, agents, and outcomes of poisoning at JOOTRH. Records of patients who presented to JOOTRH with symptoms of poisoning between January 2011 and December 2016 were retrieved. Data on age, gender, offending agents, time, and season of exposure were collected. Information on the route of exposure, motive, and clinical symptoms of poisoning was also included. Other information included the laboratory evaluation, first aid measures, period of hospitalization, and outcome of poisoning. Mean, standard deviation, frequencies and bar graphs were used to describe the demographic factors of the study population. Multivariate logistic regression was used to determine the strength of association between risk factors and outcome of poisoning among patients. The level of significance for inferential analysis was set at 5%. There were 385 cases of poisoning: 57.9% (223/385) were male, 31.9% (123/385) were 13-24 years of age, and 83.9% (323/385) of exposures were in Kisumu County. The peak time of exposure was 6:00-00:00, and 23.6% (91/385) presented 1-4 h after exposure. About 62.9% (242/385) of the cases were due to accidental poisoning. Snakebites and organophosphates (OPPs) contributed to 33.0% (127/385) and 22.1% (85/385) of all cases, respectively. About 62.1% (239/385) of exposures were oral, and 63.9% (246/385) of all cases occurred in the rainy season. Additionally, 49.2% (60/122) of intentional poisoning was due to family disputes, and 16.1% (10/62) of pre-hospital first aid involved the use of tourniquets and herbal medicine. About 28.6% (110/385) of the victims were subjected to laboratory evaluation and 83.9% (323/385) were hospitalized for between 1-5 days. Other results indicated that 80.0% (308/385) responded well to therapy, while 7.3% (28/385) died, 68% (19/28) of whom were male. Furthermore, 39.3% (11/28) of the deaths were related to OPPs. Our findings suggest that the earlier the victims of poisoning get to the hospital, the more likely they are to survive after treatment is initiated. Similarly, victims of poisoning due to parental negligence are more likely to survive after treatment compared to other causes of poisoning, including family disputes, love affairs, snakebites, and psychiatric disorders. The management of JOOTRH should consider allocating resources to support the development of poison management and control. PMID- 30274490 TI - Onchodermatitis: Where Are We Now? AB - Onchocerciasis causes debilitating pruritus and rashes as well as visual impairment and blindness. Prior to control measures, eye disease was particularly prominent in savanna areas of sub-Saharan Africa whilst skin disease was more common across rainforest regions of tropical Africa. Mass drug distribution with ivermectin is changing the global scene of onchocerciasis. There has been successful progressive elimination in Central and Southern American countries and the World Health Organization has set a target for elimination in Africa of 2025. This literature review was conducted to examine progress regarding onchocercal skin disease. PubMed searches were performed using keywords 'onchocerciasis', 'onchodermatitis' and 'onchocercal skin disease' over the past eight years. Articles in English, or with an English abstract, were assessed for relevance, including any pertinent references within the articles. Recent progress in awareness of, understanding and treatment of onchocercal skin disease is reviewed with particular emphasis on publications within the past five years. The global burden of onchodermatitis is progressively reducing and is no longer seen in children in many formerly endemic foci. PMID- 30274491 TI - Diagnostic Accuracy of the InBios Scrub Typhus DetectTM ELISA for the Detection of IgM Antibodies in Chittagong, Bangladesh. AB - Here we estimated the accuracy of the InBios Scrub Typhus DetectTM immunoglobulin M (IgM) ELISA to determine the optimal optical density (OD) cut-off values for the diagnosis of scrub typhus. Patients with undifferentiated febrile illness from Chittagong, Bangladesh, provided samples for reference testing using (i) qPCR using the Orientia spp. 47-kDa htra gene, (ii) IFA >=1:3200 on admission, (iii) immunofluorescence assay (IFA) >=1:3200 on admission or 4-fold rise to >=3200, and (iv) combination of PCR and IFA positivity. For sero-epidemiological purposes (ELISA vs. IFA >=1:3200 on admission or 4-fold rise to >=3200), the OD cut-off for admission samples was >=1.25, resulting in a sensitivity (Sn) of 91.5 (95% confidence interval (95% CI: 96.8-82.5) and a specificity (Sp) of 92.4 (95% CI: 95.0-89.0), while for convalescent samples the OD cut-off was >=1.50 with Sn of 66.0 (95% CI: 78.5-51.7) and Sp of 96.0 (95% CI: 98.3-92.3). Comparisons against comparator reference tests (ELISA vs. all tests including PCR) indicated the most appropriate cut-off OD to be within the range of 0.75-1.25. For admission samples, the best Sn/Sp compromise was at 1.25 OD (Sn 91.5%, Sp 92.4%) and for convalescent samples at 0.75 OD (Sn 69.8%, Sp 89.5%). A relatively high (stringent) diagnostic cut-off value provides increased diagnostic accuracy with high sensitivity and specificity in the majority of cases, while lowering the cut off runs the risk of false positivity. This study underlines the need for regional assessment of new diagnostic tests according to the level of endemicity of the disease given the high levels of residual or cross-reacting antibodies in the general population. PMID- 30274493 TI - Mycetoma: The Spectrum of Clinical Presentation. AB - Mycetoma is a chronic infection, newly designated by the World Health Organization (WHO) as a neglected tropical disease, which is endemic in tropical and subtropical regions. It follows implantation of infectious organisms, either fungi (eumycetomas) or filamentous bacteria (actinomycetomas) into subcutaneous tissue, from where infection spreads to involve skin, bone and subcutaneous sites, leading to both health related and socioeconomic problems. In common with other NTDs, mycetoma is most often seen in rural areas amongst the poorest of people who have less access to health care. The organisms form small microcolonies that are discharged onto the skin surface via sinus tracts, or that can burrow into other adjacent tissues including bone. This paper describes the clinical features of mycetoma, as early recognition is a key to early diagnosis and the institution of appropriate treatment including surgery. Because these lesions are mostly painless and the majority of infected individuals present late and with advanced disease, simplifying early recognition is an important public health goal. PMID- 30274495 TI - Melioidosis in the Philippines. AB - The first documented case of melioidosis in the Philippines occurred in 1948. Since then, there have been sporadic reports in the literature about travelers diagnosed with melioidosis after returning from the Philippines. Indigenous cases, however, have been documented rarely, and under-reporting is highly likely. This review collated all Philippine cases of melioidosis published internationally and locally, as well as unpublished case series and reports from different tertiary hospitals in the Philippines. In total, 25 papers and 41 cases were identified. Among these, 23 were indigenous cases (of which 20 have not been previously reported in the literature). The most common co-morbidity present was diabetes mellitus, and the most common presentations were pulmonary and soft tissue infections. Most of the cases received ceftazidime during the intensive phase, while trimethoprim-sulfamethoxazole was given during the eradication phase. The known mortality rate was 14.6%, while 4.9% of all cases were reported to have had recurrence. The true burden of melioidosis in the country is not well defined. A lack of awareness among clinicians, a dearth of adequate laboratories, and the absence of a surveillance system for the disease are major challenges in determining the magnitude of the problem. PMID- 30274496 TI - Young Adults in Endemic Areas: An Untreated Group in Need of School-Based Preventive Chemotherapy for Schistosomiasis Control and Elimination. AB - Parasitologic surveys of young adults in college and university settings are not commonly done, even in areas known to be endemic for schistosomiasis and soil transmitted helminths. We have done a survey of 291 students and staff at the Kisumu National Polytechnic in Kisumu, Kenya, using the stool microscopy Kato Katz (KK) method and the urine point-of-care circulating cathodic antigen (POC CCA) test. Based on three stools/two KK slides each, in the 208 participants for whom three consecutive stools were obtained, Schistosoma mansoni prevalence was 17.8%. When all 291 individuals were analyzed based on the first stool, as done by the national neglected tropical disease (NTD) program, and one urine POC-CCA assay (n = 276), the prevalence was 13.7% by KK and 23.2% by POC-CCA. Based on three stools, 2.5% of 208 participants had heavy S. mansoni infections (>=400 eggs/gram feces), with heavy S. mansoni infections making up 13.5% of the S. mansoni cases. The prevalence of the soil-transmitted helminths (STH: Ascaris lumbricoides, Trichuris trichiura and hookworm) by three stools was 1.4%, 3.1%, and 4.1%, respectively, and by the first stool was 1.4%, 2.4% and 1.4%, respectively. This prevalence and intensity of infection with S. mansoni in a college setting warrants mass drug administration with praziquantel. This population of young adults is 'in school' and is both approachable and worthy of inclusion in national schistosomiasis control and elimination programs. PMID- 30274494 TI - Control Strategies for Scabies. AB - Scabies is a neglected tropical disease of the skin, causing severe itching and stigmatizing skin lesions. Further, scabies leads to impetigo, severe bacterial infections, and post-infectious complications. Around 200 million people are affected, particularly among disadvantaged populations living in crowded conditions in tropical areas. After almost 50 years, research into scabies control has shown great promise, particularly in highly-endemic island settings, but these findings have not been widely adopted. Newer approaches, utilizing ivermectin-based mass drug administration, appear feasible and highly effective. Inclusion of scabies in the WHO portfolio of neglected tropical diseases in 2017 may facilitate renewed opportunities and momentum toward global control. However, further operational research is needed to develop evidence-based strategies for control in a range of settings, and monitor their impact. Several enabling factors are required for successful implementation, including availability of affordable drug supply. Integration with existing health programs may provide a cost-effective approach to control. PMID- 30274497 TI - The Skin-A Common Pathway for Integrating Diagnosis and Management of NTDs. AB - Many of the neglected tropical diseases (NTDs) have major skin manifestations. These skin-related NTDs or 'skin NTDs' cause significant morbidity and economic hardship in some of the poorest communities worldwide. We draw attention to the collective burden of skin disease and suggest that the skin be used as a platform for the integration of control activities for NTDs. The opportunities for integration are numerous, ranging from diagnosis and disease mapping to mass drug administration and morbidity management. The dermatology community has an important role to play, and will be expected to support research and control activities globally.

AB - The high prevalence of skin diseases in resource-poor settings, where health workers with sufficient knowledge of skin diseases are scarce, calls for innovative measures. Timely diagnosis and treatment of skin diseases, especially neglected tropical diseases (NTDs) that manifest with skin lesions, such as leprosy, is crucial to prevent disabilities as well as psychological and socioeconomic problems. Innovative technological methods like telemedicine and mobile health (mHealth) can help to bridge the gap between the burden of skin diseases and the lack of capable staff in resource-poor settings by bringing essential health services from central level closer to peripheral levels. Netherlands Leprosy Relief (NLR) has developed a mobile phone application called the 'SkinApp', which aims to support peripheral health workers to recognize the early signs and symptoms of skin diseases, including skin NTDs, and to start treatment promptly or refer for more advanced diagnostic testing or disease management when needed. Further research is needed to determine how greatly mHealth in general and the SkinApp in particular can contribute to improved health outcomes, efficiency, and cost-effectiveness. PMID- 30274499 TI - Hospitalizations and Deaths Associated with Diarrhea and Respiratory Diseases among Children Aged 0-5 Years in a Referral Hospital of Mauritania. AB - Diarrhea and respiratory diseases are the leading causes of morbidity and mortality among <5-year-olds worldwide, but systematic data are not available from Mauritania. We conducted a hospital-based retrospective study. Data on admissions to Mauritania's National Referral Hospital (the main pediatric referral center in the country), due to diarrhea and respiratory diseases, during 2011-2014, were analyzed. A total of 3695 children <5 years were hospitalized during this period; 665 (18.0%) due to respiratory diseases, and 829 (22.4%) due to diarrhea. Case fatality rates in the respiratory diseases and diarrhea groups were 18.0% (120/665) and 14.1% (117/829), respectively. The highest frequency of deaths due to diarrhea occurred in the age group 2-5 years (16/76; 21.0%), and due to respiratory diseases in the age group 6-12 months (32/141; 22.6%). We conclude that case fatality rates caused by respiratory diseases and diarrhea are extremely high in children hospitalized at the National Referral Hospital. These data call for intensified efforts to reduce deaths among hospitalized Mauritanian children, and also for integrated control measures to prevent and reduce the burden of both diseases. Additional studies are needed to show the effectiveness of the introduction of vaccination programs for pneumococcal diseases and rotavirus infection in the child population, which were launched in November 2013 and December 2014, respectively. PMID- 30274500 TI - Revered but Poorly Understood: A Case Report of Dendroaspis polylepis (Black Mamba) Envenomation in Watamu, Malindi Kenya, and a Review of the Literature. AB - The black mamba (Dendroaspis polylepis) ranks consistently as one of the most revered snakes in sub-Saharan Africa. It has potent neurotoxic venom, and envenomation results in rapid onset and severe clinical manifestations. This report describes the clinical course and reversal of effects of black mamba envenomation in a 13-year-old boy in the Jimba area of Malindi. The victim presented to Watamu Hospital, a low resource health facility with labored breathing, frothing at the mouth, severe ptosis and pupils non-responsive to light. His blood pressure was unrecordable, heart rate was 100 beats per minute but thready, his temperature was 35.5 degrees C, and oxygen saturation was 83%. Management involved suction to clear salivary secretions, several hours of mechanical ventilation via ambu-bagging, oxygen saturation monitoring, and the use of South African Vaccine Producers (SAVP) polyvalent antivenom. Subcutaneous adrenaline was used to stave off anaphylaxis. The victim went into cardiac arrest on two occasions and chest compressions lasting 3-5 min was used to complement artificial ventilation. Hemodynamic instability was corrected using IV infusion of ringers lactate and normal saline (three liters over 24 h). Adequate mechanical ventilation and the use of specific antivenom remain key in the management of black mamba envenomation. PMID- 30274501 TI - Low Microfilaremia Levels in Three Districts in Coastal Ghana with at Least 16 Years of Mass Drug Administration and Persistent Transmission of Lymphatic Filariasis. AB - Ghana has been implementing mass drug administration (MDA) of ivermectin and albendazole for the elimination of lymphatic filariasis (LF) since the year 2000, as part of the Global Programme to Eliminate Lymphatic Filariasis (GPELF). It was estimated that 5-6 years of treatment would be sufficient to eliminate the disease. Tremendous progress has been made over the years, and treatment has stopped in many disease endemic districts. However, despite the successful implementation of MDA, there are districts with persistent transmission. In this study we assessed the epidemiology of LF in three adjoining districts that have received at least 16 years of MDA. The assessments were undertaken one year after the last MDA. 1234 adults and 182 children below the age of 10 years were assessed. The overall prevalence of circulating filarial antigen in the study participants was 8.3% (95% CI: 6.9-9.9), with an estimated microfilaria prevalence of 1.2%. The microfilarial intensity in positive individuals ranged from 1 to 57 microfilariae/mL of blood. Higher antigen prevalence was detected in males (13.0%; 95% CI: 10.3-16.2) compared to females (5.5%; 95% CI: 4.1-7.2). The presence of infection was also highest in individuals involved in outdoor commercial activities, with the risks of infection being four- to five-fold higher among farmers, fishermen, drivers and artisans, compared to all other occupations. Using bednets or participating in MDA did not significantly influence the risk of infection. No children below the age of 10 years were found with infection. Detection of Wb123 antibodies for current infections indicated a prevalence of 14.4% (95% CI: 8.1-23.0) in antigen-positive individuals above 10 years of age. No antibodies were detected in children 10 years or below. Assessment of infection within the An. gambiae vectors of LF indicated an infection rate of 0.9% (95% CI: 0.3-2.1) and infectivity rate of 0.5% (95% CI: 0.1-1.6). These results indicate low-level transmission within the districts, and suggest that it will require targeted interventions in order to eliminate the infection.

PMID- 30274503 TI - Further observations on the fine structure of the infracerebral gland in Nereis (Annelida; Polychaeta) - C2 and C3 cells; centripetal and centrifugal fibers. AB - The infracerebral gland of Nereis is made up of three types of cells. C1 cells are hypertrophied pericapsular elements, whereas C2 and C3 cells have the morphological and cytological features of neurosecretory neurons. C2 and C3 cells give rise to centripetal "proximal processes" which extend into the brain through the midventral pocket formed by delamination of the brain capsule. Their "distal processes" terminate within the gland or its immediate vicinity. "Centrifugal fibers" arise from nerve cells located within the brain and appear to synapse upon the proximal processes of C2 cells in the region of the midventral pocket and in the ventral region of the brain. The cytology of C2 and C3 cells suggests that they are the source of distinct peptide hormones. PMID- 30274504 TI - Change of voltage-gated potassium channel 1.7 expressions in monocrotaline induced pulmonary arterial hypertension rat model. AB - PURPOSE: Abnormal potassium channels expression affects vessel function, including vascular tone and proliferation rate. Diverse potassium channels, including voltage-gated potassium (Kv) channels, are involved in pathological changes of pulmonary arterial hypertension (PAH). Since the role of the Kv1.7 channel in PAH has not been previously studied, we investigated whether Kv1.7 channel expression changes in the lung tissue of a monocrotaline (MCT)-induced PAH rat model and whether this change is influenced by the endothelin (ET)-1 and reactive oxygen species (ROS) pathways. METHODS: Rats were separated into 2 groups: the control (C) group and the MCT (M) group (60 mg/kg MCT). A hemodynamic study was performed by catheterization into the external jugular vein to estimate the right ventricular pressure (RVP), and pathological changes in the lung tissue were investigated. Changes in protein and mRNA levels were confirmed by western blot and polymerase chain reaction analysis, respectively. RESULTS: MCT caused increased RVP, medial wall thickening of the pulmonary arterioles, and increased expression level of ET-1, ET receptor A, and NADPH oxidase (NOX) 4 proteins. Decreased Kv1.7 channel expression was detected in the lung tissue. Inward rectifier channel 6.1 expression in the lung tissue also increased. We confirmed that ET-1 increased NOX4 level and decreased glutathione peroxidase-1 level in pulmonary artery smooth muscle cells (PASMCs). ET-1 increased ROS level in PASMCs. CONCLUSION: Decreased Kv1.7 channel expression might be caused by the ET 1 and ROS pathways and contributes to MCT-induced PAH. PMID- 30274505 TI - Oral findings and its association with prenatal and perinatal factors in newborns. AB - PURPOSE: This study aimed to determine the frequency of abnormalities in the newborn oral cavity and to evaluate the association with prenatal and perinatal factors. METHODS: This cross-sectional study evaluated 2,216 newborns. Oral findings were assessed in the first 24 hours of life using visual examination. Sex, weight, length, gestational age, and medical disorders at birth were recorded. Maternal demographic and medical information was also obtained. RESULTS: The most common oral findings were Bohn's nodules, Epstein's pearls, and dental lamina cysts. Other intraoral findings included odontogenic cysts, ankyloglossia, and natal teeth, among others. In logistic regression analyses, folic acid consumption during pregnancy was significantly associated with Bohn's nodules (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.23-2.55; P=0.002), Epstein's pearls (OR, 1.63; 95% CI, 1.14-2.33; P=0.007), and dental lamina cysts (OR, 1.45; 95% CI, 1.02-2.05; P=0.038). Moreover, preterm births were negatively associated with prevalence of Bohn's nodules (OR, 0.63; 95% CI, 0.50-0.80; P<=0.0001). Comparison between newborns with and without oral inclusion cysts showed that maternal folic acid and iron intake were significantly different (P<0.05). CONCLUSION: Maternal folic acid and iron intake were associated with the prevalence of oral inclusion cysts. PMID- 30274506 TI - Usefulness of the procalcitonin test in young febrile infants between 1 and 3 months of age. AB - PURPOSE: To study the usefulness of the procalcitonin (PCT) test in young febrile infants between 1 and 3 months of age. METHODS: We evaluated the medical records of 336 febrile infants between 1 and 3 months of age who visited the Emergency Department or outpatient department of Samsung Changwon Hospital from May 2015 to February 2017, and analyzed the clinical characteristics between infants in the serious bacterial infection (SBI) group and non-SBI group. RESULTS: Among the 336 infants, 38 (11.3%) had definitive SBI (bacteremia, n=3; meningitis, n=1; urinary tract infection, n=34). The mean PCT (6.4+/-11.9 ng/mL) and C-reactive protein (CRP) level (3.8+/-2.6 mg/dL), and the absolute neutrophil count (ANC) (6,984+/ 4,675) for patients in the SBI group were significantly higher than those for patients in the non-SBI group (PCT, 0.3+/-1.2 ng/mL; CRP, 1.3+/-1.6 mg/dL; ANC, 4,888+/-3,661). PCT had lower sensitivity (43.6%), but higher specificity (92.6%) and accuracy (86.9%) than CRP (92.3%, 25.3%, and 33.0%) for identifying SBI. The area under the receiver operating characteristic curves (AUCs) for definitive SBI were PCT 77.0%, CRP 80.8%, WBC 56.8%, ANC 67.8%, and PLT 48.1%. The AUCs for definitive SBI were PCT+CRP 85.4%, PCT+WBC 77.2%, PCT+ANC 81.3%, CRP+WBC 80.1%, and CRP+ANC 81.6%. CONCLUSION: Our results suggest that the PCT test or a combination of PCT and CRP tests is a more accurate and specific biomarker to detect and rule out SBIs. PMID- 30274508 TI - Assessing nociception: steps towards intraoperative "full monitoring". PMID- 30274507 TI - The changes of prevalence and etiology of pediatric pneumonia from National Emergency Department Information System in Korea, between 2007 and 2014. AB - PURPOSE: Understanding changes in pathogen and pneumonia prevalence among pediatric pneumonia patients is important for the prevention of infectious diseases. METHODS: We retrospectively analyzed data of children younger than 18 years diagnosed with pneumonia at 117 Emergency Departments in Korea between 2007 and 2014. RESULTS: Over the study period, 329,380 pediatric cases of pneumonia were identified. The most frequent age group was 1-3 years old (48.6%) and the next was less than 12 months of age (17.4%). Based on International Classification of Diseases, 10th revision diagnostic codes, confirmed cases of viral pneumonia comprised 8.4% of all cases, pneumonia due to Mycoplasma pneumoniae comprised 3.8% and confirmed cases of bacterial pneumonia 1.3%. The prevalence of confirmed bacterial pneumonia decreased from 3.07% in 2007 and 4.01% in 2008 to 0.65% in 2014. The yearly rate of pneumococcal pneumonia also decreased from 0.47% in 2007 to 0.08% in 2014. A periodic prevalence of M. pneumoniae pneumonia (MP) was identified. CONCLUSION: The increased number of patients with pneumonia, bacterial pneumonia, pleural effusion, and empyema in 2011 and 2013-2014 resulted from an MP epidemic. We provide evidence that the frequency of confirmed cases of bacterial pneumonia and pneumococcal pneumonia has declined from 2007 to 2014, which can simultaneously reflect the effectiveness of the pneumococcal conjugate vaccine. PMID- 30274509 TI - Systematic Analysis of Bottlenecks in a Multibranched and Multilevel Regulated Pathway: The Molecular Fundamentals of l-Methionine Biosynthesis in Escherichia coli. AB - To produce chemicals and fuels from renewable resources, various strategies and genetic tools have been developed to redesign pathways and optimize the metabolic flux in microorganisms. However, in most successful cases, the target chemicals are synthesized through a linear pathway, and regular methodologies for the identification of bottlenecks and metabolic flux optimization in multibranched and multilevel regulated pathways, such as the l-methionine biosynthetic pathway, have rarely been reported. In the present study, a systematic analysis strategy was employed to gradually reveal and remove the potential bottlenecks limiting the l-methionine biosynthesis in E. coli. 80 genes in central metabolism and selected amino acids biosynthetic pathways were first repressed or upregulated to probe their effects on l-methionine accumulation. The l-methionine biosynthetic pathway was then modularized and iteratively genetic modifications were performed to uncover the multiple layers of limitations and stepwise improve the l methionine titer. The metabolomics data further revealed a more evenly distributed metabolic flux in l-methionine biosynthesis pathway of the optimal strain and provided valuable suggestions for further optimization. The optimal strain produced 16.86 g/L of l-methionine in 48 h by fed-batch fermentation. This work is the first to our knowledge to systematically elucidate the molecular fundamentals of multilevel regulation of l-methionine biosynthesis. It also demonstrated that the systematic analysis strategy can boost our ability to identify the potential bottlenecks and optimize the metabolic flux in multibranched and multilevel regulated pathways for the production of corresponding chemicals. PMID- 30274510 TI - Electrochemical-Signal-Amplification Strategy for an Electrochemiluminescence Immunoassay with g-C3N4 as Tags. AB - Signal amplification for electrochemiluminescence (ECL) has conventionally been achieved by employing effective matrixes that can accelerate the electrochemical redox processes or carry more electrochemiluminophores. Herein, a convenient signal-amplification strategy was proposed for an ECL immunoassay with carboxylated g-C3N4 nanosheets (NSs) as tags and carcinoembryonic antigen (CEA) as the model target via electrochemically pretreating the substrate: a glassy carbon electrode (GCE) modified with a polymerized 2-aminoterephthalic acid (ATA) film (GCE/ATA). Bioconjugates of g-C3N4 NSs and the signal CEA antibody (Ab2) (i.e., g-C3N4 NS-Ab2) were immobilized on GCE/ATA via a sandwich immunoreaction to form GCE/ATA-Ab1-Ag-Ab2-NSs. Electrochemical-impedance spectroscopy and potential-resolved ECL characterization proved that GCE/ATA plays an important role in the electron-transfer resistance ( Ret) of the GCE/ATA-Ab1-Ag-Ab2-NSs for ECL and that successively scanning GCE/ATA-Ab1-Ag-Ab2-NSs from 0 to -1.6 V in K2S2O8- and H2O2-containing medium could reduce the Ret and bring out 3.3-times enhanced ECL at the 10th scan cycle compared with that of the 1st scan cycle, which was about 10.2 times the ECL of the GCE/ATA-Ab1-Ag-Ab2-NSs in medium containing merely K2S2O8. Inspired by this, direct and successive scanning of GCE/ATA in K2S2O8- and H2O2-containing medium was employed during fabrication, which dramatically reduced the Ret of GCE/ATA-Ab1-Ag-Ab2-NSs and brought out obviously enhanced ECL responses for selectively determining CEA from 0.1 pg/mL to 1 ng/mL, with a detection limit of 3 fg/mL. PMID- 30274511 TI - Ionic Ga-Complexes of Alkylidene- and Arylmethylidenemalonates and Their Reactions with Acetylenes: An In-Depth Look into the Mechanism of the Occurring Gallium Chemistry. AB - A new synthetic concept was suggested in the chemistry of substituted methylidenemalonates that enables their utilization as 1,2-zwitterionic synthons. This strategy is to generate liquid ionic Ga complexes from methylidenemalonates and GaHal3 with a strict 3/4 composition and then use them in further synthesis. A number of complexes with different metal halides have been synthesized and studied in detail. The unique properties of gallium among all metals have been demonstrated and explained. On the basis of the discovered new class of gallium complexes of methylidenemalonates, a number of novel reactions with acetylenes have been elaborated, which are unknown in the conventional chemistry of methylidenemalonates. The main demonstrated process is a three-component addition to a triple bond involving halide anions, leading to the formation of polyfunctional vinyl halides with high E-selectivity. The mechanism has been studied experimentally in fine detail. Application of specially optimized 71Ga NMR spectroscopy makes it possible to take an in-depth look into the gallium chemistry in a new light. In particular, the key participation of GaHal4- anions in the occurring transformations has been established. PMID- 30274512 TI - Online Gas-Free Electrodialytic KOH Eluent Generator for Ion Chromatography. AB - An online gas-free KOH electrodialytic eluent generator (EDG) with two-membrane configuration is described for ion chromatography (IC). A central eluent channel is separated from two outer regenerant channels bearing KOH solution (or one is water) by stacked cation-exchange membranes (sCEMs) and a bipolar membrane (BPM) plus stacked CEMs (BPM-sCEMs), in which the anion-exchange membrane (AEM) of BPM is facing the central channel (the anode direction). Independent fluid input or output ports address all channels. One platinum screen electrode is put in each outer channel, and the sCEM side is anode with respect to the cathode of the BPM sCEM side. Under the electric field, enhanced water splitting at the intermediate layer of BPM will occur, offering hydroxide and hydronium; hydroxide electromigrates through AEM into the central channel, while the potassium of KOH feed solution at the anode migrates into the central channel to combine with hydroxide to form a solution of KOH. Because the central eluent channel is spatially isolated from both electrodes, the generated KOH solution is gas-free and no gas-removal device is required. More important, the AEM side of BPM is contactless with the alkaline solution, nearly avoiding possible AEM degradation when immersed into concentrated alkaline solution. This ensures long-term running stability of the EDG and high purity of the produced KOH solution (as indicated by the typical suppressed background conductance of 0.28 MUS/cm). The EDG has a pressure tolerance (at least 21 MPa), and the produced KOH concentration is up to 101 MUeq/min with near-unity faradaic efficiency. When operated in both isocratic and gradient modes, the EDG demonstrates excellent reproducibility, as indicated by the retention time of RSD <= 0.08% and the peak area of RSD <= 0.6%. To the best of our knowledge, this is the first description of gas-free EDG matched conventional IC system. PMID- 30274513 TI - Photogeneration of Quinone Methides as Latent Electrophiles for Lysine Targeting. AB - Latent electrophiles are nowadays very attractive chemical entities for drug discovery, as they are unreactive unless activated upon binding with the specific target. In this work, the utility of 4-trifluoromethyl phenols as precursors of latent electrophiles, quinone methides (QM), for lysine-targeting is demonstrated. These Michael acceptors were photogenerated for specific covalent modification of lysine residues using human serum albumin (HSA) as a model target. The reactive QM-type intermediates I or II, generated upon irradiation of 4-trifluoromethyl-1-naphthol (1)@HSA or 4-(4-trifluorometylphenyl)phenol (2)@HSA complexes, exhibited chemoselective reactivity toward lysine residues leading to amide adducts, which was confirmed by proteomic analysis. For ligand 1, the covalent modification of residues Lys106 and Lys414 (located in subdomains IA and IIIA, respectively) was observed, whereas for ligand 2, the modification of Lys195 (in subdomain IIA) took place. Docking and molecular dynamics simulation studies provided an insight into the molecular basis of the selectivity of 1 and 2 for these HSA subdomains and the covalent modification mechanism. These studies open the opportunity of performing protein silencing by generating reactive ligands under very mild conditions (irradiation) for specific covalent modification of hidden lysine residues. PMID- 30274514 TI - Next Generation Histology-Directed Imaging Mass Spectrometry Driven by Autofluorescence Microscopy. AB - Histology-directed imaging mass spectrometry (IMS) is a spatially targeted IMS acquisition method informed by expert annotation that provides rapid molecular characterization of select tissue structures. The expert annotations are usually determined on digital whole slide images of histological stains where the staining preparation is incompatible with optimal IMS preparation, necessitating serial sections: one for annotation, one for IMS. Registration is then used to align staining annotations onto the IMS tissue section. Herein, we report a next generation histology-directed platform implementing IMS-compatible autofluorescence (AF) microscopy taken prior to any staining or IMS. The platform enables two histology-directed workflows, one that improves the registration process between two separate tissue sections using automated, computational monomodal AF-to-AF microscopy image registration, and a registration-free approach that utilizes AF directly to identify ROIs and acquire IMS on the same section. The registration approach is fully automated and delivers state of the art accuracy in histology-directed workflows for transfer of annotations (~3-10 MUm based on 4 organs from 2 species) while the direct AF approach is registration-free, allowing targeting of the finest structures visible by AF microscopy. We demonstrate the platform in biologically relevant case studies of liver stage malaria and human kidney disease with spatially targeted acquisition of sparsely distributed (composing less than one tenth of 1% of the tissue section area) malaria infected mouse hepatocytes and glomeruli in the human kidney case study. PMID- 30274515 TI - Synthesis and Characterization of PDMS-PMOXA-Based Polymersomes Sensitive to MMP 9 for Application in Breast Cancer. AB - Cytotoxic compounds used to treat cancer are often associated with adverse events. The development of formulations activated by tumor-specific triggers would allow a reduction of systemic exposure while maintaining therapeutic concentrations in the tumor. One enzyme with proteolytic activity reported to be involved in tumor progression and assumed to be enhanced in the tumor environment is the matrix metalloproteinase 9 (MMP-9). In our study, we aimed to develop surface-modified PDMS-PMOXA polymersomes able to release their cytotoxic payload upon digestion by MMP-9. To test the applicability of such a system in breast cancer, this tumor entity was assessed for MMP-9 expression, supporting breast cancer as a potential target. The surface-modified polymersomes were synthesized and formulated resulting in paclitaxel-loaded particles of about 320 +/- 153.15 nm in size with a surface potential of 0.04 +/- 0.007 mV. After the expression and activity of MMP-9 in MCF7 cells were verified, this cell line was used for further analysis. Treatment of MCF7 cells with the polymersomes significantly reduced cell viability, this effect was abolished after addition of MMP inhibitors, suggesting proteolytic activation. In zebrafish embryos, the polymersomes were observed in the circulation with some enrichment in liver and agglomerates in the caudal veins. Importantly, in zebrafish embryos xenografted with mKate2-expressing MCF7 cells, the amount of tumor cells, quantified by detecting the copies of the heterologously expressed fluorescent protein, significantly decreased after treatment with PDMS-PMOXA-SRL-paclitaxel polymersomes. Taken together, our data suggest that polymersomes modified with an MMP-9 labile peptide and loaded with paclitaxel can be formulated, and that these particles exert pharmacological activity upon enzymatic digestion. PMID- 30274516 TI - Stochastic Transition State Theory. AB - Kramers's original paper on the diffusion model of chemical reactions was based on the consideration that only the barrier region determines the outcome of transmission over a barrier. Subsequently it became understood that Kramers's approach was identical to variational transition state theory (VTST) and as such used only thermodynamic information. Here, using Kramers's philosophy in conjunction with perturbation theory and the realization that the dynamics which is rate-determining usually occurs in the vicinity of the transition state leads to a novel stochastic rate theory in which the momentum change induced by the medium is the stochastic variable. A first successful application of the theory is to the old and challenging problem of motion over a cusped barrier. This has implications for the study of transition path time distributions as well as the theory of tunneling via nonadiabatic coupling. PMID- 30274517 TI - An NIR-Guided Aggregative and Self-Immolative Nanosystem for Efficient Cancer Targeting and Combination Anticancer Therapy. AB - Nanosized drug delivery systems based on polymeric structures have been proven to be promising approaches for cancer treatments. However, few have been effective at selectively targeting cancer cells and releasing drug at desired tumor sites. Here, we report a "smart" polymeric nanoplatform, which could actively accumulate at tumor sites and dissociate to release encapsulated cargos upon the irradiation of a near-infrared (NIR) laser. This nanoplatform composed of a novel amphiphilic block copolymer poly(propylene sulfide)-poly( N-isopropylacrylamide- co- N, N dimethylacrylamide) (PPS-P(NIPAM- co-DMAA)) formed spherical structures in aqueous solution and responded to both oxidants and elevated temperature. Upon laser irradiation at 808 nm, the NIR light was efficiently converted to local heat by the doxorubicin (DOX) and indocyanine green (ICG) co-loaded micelles for enhanced cell uptake and therapeutic efficacy. It showed that the micelles effectively accumulated at the tumor sites guided by the application of an NIR laser in in vivo studies, exhibiting a 6-time greater and much faster targeting effect compared to the nonirradiation group. The effective tumor growth inhibition by the drug-loaded micelles upon laser irradiation demonstrated significant tumor inhibition without regrowth in 16 days. This micellar nanoplatform for precise NIR-guided cancer targeting and combination therapy provides a novel and robust strategy for cancer therapy. PMID- 30274518 TI - Self-Assembly of Nanocubic Molecular Capsules via Solvent-Guided Formation of Rectangular Blocks. AB - We investigate the mechanism underlying the self-assembly of gear-shaped amphiphilic molecules into a highly ordered nanocubic capsule ("nanocube") in aqueous methanol. Simulation results show that the solvent molecules play a significant role in the assembly process by directing the primitive intermediates to orthogonal/rectangular shapes, thus creating appropriate building blocks for cubic assembly while avoiding off-pathway stacked aggregates. Free-energy analyses reveal that the interplay of the direct intermonomer interaction and the solvent-mediated repulsion between large aromatic cores (via preferential solvation of methanol on hydrophobic surfaces) leads to the strong trend for perpendicular binding of monomers and hence the solvent-guided formation of rectangular blocks. Furthermore, we report the self-assembly simulation of the nanocube using replica exchange with solute tempering and demonstrate that the simulation can predict a highly ordered nanocapsule structure, assembly intermediates, and encapsulated molecules, which helps promote computer-aided design of functional molecular self-assemblies in explicit solvent. PMID- 30274519 TI - Interfacial Properties of Polyelectrolyte-Surfactant Aggregates at Air/Water Interfaces. AB - The transport, equilibrium properties, and mechanics of stable, rodlike surfactant-polyelectrolyte aggregates, poly(cetyltrimethylammonium vinyl benzoate) or pCTVB, are characterized at air/water interfaces for bulk concentrations near and below the critical aggregation concentration. The surfactant drives the transport to air/water interfaces, while the polyelectrolyte provides elasticity to the coated interfaces and appears to remain adsorbed after the bulk solution is exchanged with water. The processing of interfaces is shown to allow the interfacial tension of the interface to be changed significantly while maintaining a high dilatational elasticity. The results of this work provide a tool to control interfacial properties through design of polyelectrolyte-surfactant complexes. PMID- 30274520 TI - Distribution Profiles of Melamine and Its Derivatives in Indoor Dust from 12 Countries and the Implications for Human Exposure. AB - Melamine and its derivatives (i.e., ammeline, ammelide, and cyanuric acid) are extensively used in household products, such as furniture, dinnerware, and food utensils. Nevertheless, limited information is available on human exposures, other than dietary sources, to melamine and its derivatives. In this study, the occurrence of melamine and its derivatives was determined, for the first time, in 341 samples of indoor dust, collected from 12 countries. All of the dust samples contained target analytes, with global median concentrations of 1800, 1100, 48, and 45 ng/g for melamine, cyanuric acid, ammelide, and ammeline, respectively. The total concentrations of melamine and its derivatives varied among countries in the following decreasing order: United States (median: 17 000 ng/g) > Japan (8400) > China (8000) > South Korea (7300) > Saudi Arabia (4400) > Romania (4300) > Greece (3400) > Kuwait (2400) > Vietnam (2300) > Colombia (1300) > Pakistan (820) > India (430). Correlation analysis indicated the existence of multiple and varied sources for melamine and cyanuric acid. Estimated daily intakes of melamine via indoor dust ingestion were at least 2 orders of magnitude below the current tolerable daily intake. PMID- 30274521 TI - Methionine Promotes Milk Protein and Fat Synthesis and Cell Proliferation via the SNAT2-PI3K Signaling Pathway in Bovine Mammary Epithelial Cells. AB - Methionine (Met) plays a critical regulatory role in milk production, however, the molecular mechanism of action of Met is largely unknown. This study therefore aimed to investigate the influence of Met on milk synthesis in and proliferation of bovine mammary epithelial cells (BMECs) and explore the underlying mechanism. BMECs cultured in fetal bovine serum (FBS) free Dulbecco's modified eagle's medium (DMEM)/F-12 medium were treated with Met (0, 0.3, 0.6, 0.9, and 1.2 mM). Results showed that Met (0.6 mM) significantly increased milk protein and fat synthesis and cell proliferation. Met stimulation also increased mTOR phosphorylation and protein expression of SREBP-1c and Cyclin D1. Gene function study approaches further revealed that SNAT2 is a key regulator of these signaling pathways. PI3K inhibition experiments demonstrated that SNAT2 stimulates these pathways through regulating PI3K activity, and SNAT2 inhibition experiments further revealed that SNAT2 is required for Met to activate PI3K. Furthermore, immunofluorescence observation detected that Met stimulates SNAT2 cytoplasmic expression. Collectively, these findings demonstrate that Met positively regulates milk protein and fat synthesis and cell proliferation via the SNAT2-PI3K signaling pathway in BMECs.

AB - Probiotics represents an alternative to replace antibiotics as growth promoters in animal feed and are able to control enteric bacterial diseases and to improve gut immunity. Saccharomyces cerevisiae RC016 showed previously inhibition/coagregation of pathogens) and mycotoxins adsorbent ability (aflatoxin B1, ochratoxin A and zearalenone). The aim of this work was to evaluate beneficial properties of S. cerevisiae RC016 in a non-inflammatory in vivo model in weaned piglets and in an intestinal inflammation ex vivo model induced by the mycotoxin deoxynivalenol (DON). Secretory immunoglobulin A (s-IgA) levels, intestinal cytokines, goblet cells and production parameters were evaluated in a pig model. For the in vivo assays, twelve pigs were weaned at 21 days and assigned to two groups: Control (n=6) and Yeast (n=6). Animals received yeast strain for three weeks. After 22 days the small intestine was recovered for determination of goblet cells and s-IgA. For the ex vivo assay, jejunal explants were obtained from 5 weeks old crossbred piglets and treated as follow: (1) control; (2) treated for 3 h with 10 MUM DON used as an inflammatory stressor; (3) incubated with 107 cfu/ml yeast strain; (4) pre-incubated 1 h with 107 cfu/ml yeast strain and then treated for 3 h with 10 MUM DON. CCL20, interleukin (IL) 1beta, IL-8 and IL-22 gene expression was determined by qPCR. Oral administration of S. cerevisiae RC016 increased s-IgA, the number of goblet cells in small intestine and all the growth parameters measured. In the ex vivo model, the cytokine profile studied showed a potential anti-inflammatory effect of the administration of the yeast. In conclusion, S. cerevisiae RC016 is a promising candidate for feed additives formulation to improve animal growth and gut immune system. This yeast strain could be able to improve the gut health through counteracting the weaning-associated intestinal inflammation in piglets.

AB - On 2 September 1964, one day after the Act Respecting Discrimination in Employment was introduced in Quebec, Gloria Clarke Baylis, a British-trained Caribbean migrant nurse, inquired about a permanent part-time nursing position at the Queen Elizabeth Hotel (QEH). In response, she was told that the position had already been filled. Less than a year later, Gloria appeared as the key witness in Her Majesty the Queen, Complainant v. Hilton of Canada Ltd., Accused, to determine whether the QEH violated the new legislation. Drawing on excerpts from the court transcript, this article expands and complicates intersectionality as a theoretical framework to include other markers of difference. Critical to this discussion are two interrelated concerns: first, the connection between Gloria's experience at the QEH and Black women's historical relationship to nursing; second, how her subjectivity and identity influenced her decision to pursue the lawsuit.

AB - The visualization of mental illness has attracted substantial attention from scholars in recent decades. Due to the invisible nature of mental disorders, this work has stressed the importance of representations in shaping perceptions of mental illness. In the second half of the 20th century, advertisements for psychopharmaceutical medications became important avenues through which mental illness was made visible. This article analyzes how drug advertisements portrayed mentally ill individuals in medical journal advertisements from 14 countries between 1953 and 2005. We argue that a shift in representations occurred in the 1980s: whereas earlier campaigns were dominated by images of the mentally ill suffering in isolation, the post-1980s period was marked by a trend toward "positive" imagery, social inclusion, and ordinariness. This shift re-imagines the role of psychopharmaceuticals and who might be understood as mentally ill, reflecting changes in global marketing and the arrival of the "happiness turn" within the pharmaceutical industry.

AB - Laughter played a crucial strategic role in the fight against clericalism and religion in France during the second half of the 19th century and the first half of the 20th century. The cultural output from this polemical use of laughter is contrasted with a "scholarly literature," which fought against religion in a radically different manner that featured reason facing obscurantism and prejudice. Drawing on a study of the contributions dealing with "the psychology of religion" or "hieropsychology" published in the Revue de l'hypnotisme, I will try to show that there also exists a "scholarly ridicule," the forms, codes, and uses of which are characteristic of the anticlerical laughter associated with "medical materialism."

AB - From World War II to the end of 20th century, the types of patients undergoing orthodontic treatment and their reasons for doing so changed significantly. In the 1950s and 1960s, Canadian parents were told that orthodontics would "cure" inferiority complexes and protect children with crooked teeth, especially girls, from a life of delinquency and missed opportunities. By the last two decades of the 20th century, the consumer health movement and rising incomes empowered patients to decide which treatments were right for them, and an increasing number of adult patients sought orthodontic treatment to improve their appearance. Orthodontists never abandoned their claim that orthodontic treatment could improve psychological health, as while health psychologists and other researchers increasingly called this into question. But orthodontists did begin to place greater emphasis on aesthetics as a reason for treatment, and orthodontics became part of a much larger explosion in "cosmetic dentistry" procedures that came to include tooth whitening and veneers.

How had this New Yorker, recently relieved of a jail sentence, learned of Medicare in the distant prairie province? And why was his song never released? This paper traces the ballad's fortunes through the papers of composer Earl Robinson (University of Washington) and the archives of the American Medical Association. It is situated in the historiography of folk revival and the expatriate adventures of artistic Americans persecuted in the McCarthy era. PMID- 30274528 TI - Despite Being "Known, Highly Promiscuous and Active": Presumed Heterosexuality in the USPHS's STD Inoculation Study, 1946-48. AB - The Sexually Transmitted Disease Inoculation Study of the United States Public Health Service (USPHS) was a short-term deliberate exposure experiment into the prevention of venereal diseases. Between 1946 and 1948, over 1,300 Guatemalan prisoners, psychiatric patients, soldiers, and sex workers were exposed to syphilis, gonorrhoea, and chancroid. USPHS researchers initially proposed hiring sex workers to "naturally" transmit venereal diseases to male subjects who would then be given various prophylaxes. The researchers were interested in studying the effectiveness of new preventative measures. In other words, the USPHS study was designed to transmit venereal diseases heterosexually from an "infected" female body to the men who, it was assumed, were sexually isolated subjects. However, the researchers did record instances of male-to-male disease transmission among their subject populations, instances that challenged the presumption of heterosexuality on which the study was based.

AB - PURPOSE: Home-time (the number of days spent at home during the first 3 months after stroke) shows a strong association with the modified Rankin scale (mRS). We studied whether Home-time was also a determinant of quality-of-life and medical care costs after ischemic stroke, and assessed factors delaying discharge home. MATERIALS AND METHODS: Five hundred and sixty nine patients participated in a retrospective study when returning for an in-person visit after an ischemic stroke. Home-time, mRS, EQ-5D-3L, inpatient and outpatient resource utilization, use of mobility aids, changes to home and car, comorbidities were recorded. RESULTS: Each additional Home-time day was significantly associated with an increase in utility of 0.0056 (p < 0.0001) and an in- and outpatient cost saving of $99 (p = 0.0158). Requiring extra material support significantly decreased Home-time by 76 days (including: requiring home changes: -68 days, car alterations: -49 days, needing a wheelchair: -80 days or walker: -71 days, needing bed or bath rails: -79 days). This univariable effect was confirmed in multivariable analysis when comparing with patients having the same disability level without requiring material support. CONCLUSIONS: Home-time is a stroke outcome associated with disease severity, healthcare costs and patient wellbeing. Streamlining the discharge process for those requiring extra material support may lead to cost savings and higher quality-of-life. Implications for rehabilitation Delays in discharge from the acute hospital or rehabilitation facility are incurred when patients need extra material support in order to return home. Staff from the discharging facility should assist families by giving timely information on the availability and the cost of wheel chairs and walkers; and explaining and planning the need of a stair lift, bed and bath rails as well as car modifications. Planning the discharge process with the families will lead to a more rapid return home and will result in reduced overall health care costs and higher quality of life for the patients. PMID- 30274530 TI - Hyperbaric oxygen therapy ameliorates osteonecrosis in patients by modulating inflammation and oxidative stress. AB - Early stages of avascular necrosis of the femoral head (AVNFH) can be conservatively treated with hyperbaric oxygen therapy (HBOT). This study investigated how HBOT modulates inflammatory markers and reactive oxygen species (ROS) in patients with AVNFH. Twenty-three male patients were treated with two cycles of HBOT, 30 sessions each with a 30 days break between cycles. Each session consisted of 90 minutes of 100% inspired oxygen at 2.5 absolute atmospheres of pressure. Plasma levels of tumor necrosis factor alfa (TNF-alpha), interleukin 6 (IL-6), interleukin 1 beta (IL-1beta) and ROS production were measured before treatment (T0), after 15 and 30 HBOT sessions (T1 and T2), after the 30-day break (T3), and after 60 sessions (T4). Results showed a significant reduction in TNF-alpha and IL-6 plasma levels over time. This decrease in inflammatory markers mirrored observed reductions in bone marrow edema and reductions in patient self-reported pain. PMID- 30274532 TI - Contribution assessment of multiparameter optimization descriptors in CNS penetration. AB - Assessment of the influence of six physicochemical properties used in the multiparameter optimization (MPO) approach for chemical penetration of the blood brain barrier was carried out by means of application of logistic regression and multiple linear regression, using a data set of 578 diverse chemicals. It was found that use of an aggregation MPO-score descriptor did not give satisfactory results with central nervous system (CNS)/non-CNS classification. Thus an application of the MPO approach for CNS penetration is ambiguous. An alternative to the MPO approach in this work contains detailed (quantitative) structure activity relationship analysis using a number of methods (linear discriminant analysis, random forest, support vector machine, Gaussian process). Three properties (molecular weight, number of H-bond donors and octanol-water partition coefficient) yielded optimal categorical models with modest statistical parameters (accuracy 0.730-0.765 for CNS/non-CNS classification). The poor statistics of regression models for the common data set suggested the presence of subsets with different mechanisms of penetrations. Based on graphic comparison of experimental and calculated Cu,b values, subset clusters have satisfactory statistics. The regression models obtained allowed the estimation of descriptor contributions in log Cu,b. This means that medicinal chemists now have a simple additive scheme for at least preliminary quantitative assessment of this important pharmacokinetic parameter. PMID- 30274533 TI - SAR and QSAR models of cyclooxygenase-1 (COX-1) inhibitors. AB - Cyclooxygenase-1 (COX-1) is one isoform of COX, and it is a main target of nonsteroidal anti-inflammatory drugs (NSAIDs). It is important to develop efficient and selective COX-1 inhibitors. In this work, 12 classification models for 1530 cyclooxygenase-1 (COX-1) inhibitors were built by support vector machine (SVM), decision tree (DT) and random forest (RF) methods. The best classification model (model 1A) was built by SVM with MACCS fingerprints. The classification accuracies for the training and test sets were 99.67% and 97.39%, respectively. The Matthews correlation coefficient (MCC) of the test set was 0.94. We also divided the 1530 COX-1 inhibitors into nine subsets according to their different scaffolds using Kohonen's self-organizing map (SOM). In addition, six quantitative structure-activity relationship (QSAR) models for 181 COX-1 inhibitors whose IC50 were measured by enzyme immunoassay were built by multiple linear regression (MLR) and SVM. The best QSAR model (model 5A) was built by SVM with CORINA Symphony descriptors. The correlation coefficients of the training and test sets are 0.93 and 0.84, respectively. The models built in this study can be obtained from the authors. PMID- 30274534 TI - An Evaluation of SPARC Protein as a Serum Biomarker of Chronic Rhinosinusitis. AB - Objective Precision medicine initiatives for chronic rhinosinusitis (CRS) management suggest tailoring treatment to the patient's individual disease profile; however, serum biomarkers for evaluation of disease activity or predicting response to therapy are lacking in CRS. Epithelial-to-mesenchymal transition (EMT) has been described as a component of barrier dysfunction in CRS. SPARC (secreted protein acidic and rich in cysteine) is a marker of EMT that has previously been identified in sinus epithelium by gene expression profiling. We wished to determine if SPARC could represent a serum biomarker for CRS by verifying (1) if SPARC could be detected in serum, (2) whether levels were sensitive to disease burden reduction following surgery, and (3) if it could predict response to therapy. Study Design Prospective. Setting Tertiary care center. Subjects Patients with CRS undergoing endoscopic sinus surgery (ESS). Methods Twenty-six patients undergoing ESS for CRS were prospectively recruited. Serum was collected at the time of surgery and 4 months following ESS and SPARC level measured using enzyme-linked immunosorbent assay. Postoperative outcome was characterized as "remission" or "unfavorable" based on symptomatology and endoscopy. Results SPARC could be detected and measured in serum in all subjects. Following ESS, SPARC levels decreased by 33% ( P = .005) but did not predict evolution at 4 months postsurgery ( P = .94). Conclusion SPARC may be an interesting serum biomarker of disease activity in CRS, as it can be reliably measured and decreases following successful reduction of disease burden after surgery. However, it does not predict post-ESS evolution, suggesting that the link between EMT and outcome is not linear. PMID- 30274536 TI - Cutting-edge evidence of adjuvant treatments for gastric cancer. AB - INTRODUCTION: In recent decades, adjuvant therapy has secured a firm position in the treatment of gastric cancer by improving patient prognosis. Currently, standard therapy varies between East Asia, Europe and North America due to heterogeneities of the tumor, race, medical environment and/or surgical procedure. Although adjuvant strategies, proved effective in each region and implemented to clinical practice, certain patient populations with advanced gastric cancer show recurrence and a fatal prognosis. The development of a universal adjuvant therapy with a high efficacy and acceptable adverse events or with less toxicity and non-inferiority seems to have become urgent and imperative. Areas covered: In this review, we aimed to summarize the current knowledge regarding adjuvant therapies for gastric cancer, including chemotherapy, chemoradiotherapy and molecular targeted therapy, based on clinical trials and to introduce the pivotal ongoing phase III trials. Expert commentary: The efficacy of adjuvant therapy to prevent recurrence remains insufficient although several trials have shown a significant benefit in patients with localized advanced gastric cancer. The development of more effective and universal multimodal adjuvant therapy is required.

AB - We report the synthesis and characterisation of a novel series of triazole benzenesulfonamide derivatives, which incorporate the general pharmacophore associated with carbonic anhydrase (CA, EC 4.2.1.1) inhibitors. The synthesised compounds were tested in vitro against four human carbonic anhydrase (hCA, EC 4.2.1.1) isozymes, hCA I, hCA II, hCA IV and hCA IX. The obtained results showed that the tumour-associated hCA IX was the most sensitive to inhibition with the synthesised derivatives, with the triazolo-pyridine benzenesulfonamides 14, 16 and 17 being the most effective inhibitors. Some selected compounds were chosen for a single dose anti-proliferative activity testing against a panel of 57 human tumour cell lines and show some anti-proliferative activity ex vivo.

AB - Professional American football games are recorded in digital video with multiple cameras, often at high resolution and high frame rates. The purpose of this study was to evaluate the accuracy of a videogrammetry technique to calculate translational and rotational helmet velocity before, during and after a helmet impact. In total, 10 football impacts were staged in a National Football League (NFL) stadium by propelling helmeted 50th percentile male crash test dummies into each other or the ground at speeds and orientations representative of concussive impacts for NFL players. The tests were recorded by experienced sports film crews to obtain video coverage and quality typically available for NFL games. A videogrammetry procedure was used to track the position and rotation of the helmet throughout the relevant time interval of the head impact. Compared with rigidly mounted retroreflective marker three dimensional (3-D) motion tracking that was concurrently collected in the experiments, videogrammetry accurately calculated changes in translational and rotational velocity of the helmet using high frame rate (two cameras at 240 Hz) video (7% and 15% error, respectively). Low frame rate (2 cameras at 60 Hz) video was adequate for calculating pre-impact translational velocity but not for calculating the translational or rotational velocity change of the helmet during impact.

AB - Motion analysis offers objective insight into biomechanics, rehabilitation progress and return to sport readiness. This study examined changes in three dimensional movement patterns during drop jump landing between early and late stages of rehabilitation in adolescent athletes following anterior cruciate ligament reconstruction (ACLR). Twenty-four athletes (58% female; mean age 15.4 years, SD 1.2) with unilateral ACLR underwent motion analysis testing 3-6 months and again 6-10 months post-operatively. Kinematics and kinetics were compared between visits and between limbs using repeated measures ANOVA. The operative side exhibited lower vertical ground reaction force, less energy absorption and lower sagittal external moments at the knee and ankle, and lower peak dorsiflexion angles compared with the non-operative side regardless of visit. Between visits, hip and knee flexion increased bilaterally, as well as hip flexion moments and energy absorption. During early rehabilitation following ACLR, adolescent athletes reduced flexion and loading of the knee and ankle on their operative limb. Motion and loading increased over time, particularly at the hip, but remained reduced at the knee and ankle 6-10 months post-operatively.

AB - A series of 2-arylbenzo[b]furan-appended 4-aminoquinazoline hybrids were prepared and evaluated for cytotoxicity in vitro against the human lung cancer (A549), colorectal adenocarcinoma (Caco-2), hepatocellular carcinoma (C3A) and cervical cancer (HeLa) cell lines. Compounds 10d and 10j exhibited significant cytotoxicity against the C3A and Caco-2 cell lines and induced apoptosis in these cell lines. Likewise, compounds 10d and 10e exhibited significant inhibitory activity towards epidermal growth factor receptor-tyrosine kinase phosphorylation (IC50 values of 29.3 nM and 31.1 nM, respectively) against Gefitinib (IC50 = 33.1 nM). Molecular docking of compounds 10 into EGFR-TK active site suggests that they bind to the region of EGFR like Gefitinib does. [Formula: see text].

AB - Objective To examine the effect of xylitol nasal irrigation in a large sample size of patients who had undergone nasal surgery. Study Design Double-blinded randomized controlled crossover study. Setting Tertiary referral center. Methods The study included 100 patients with sinonasal disease who underwent endoscopic sinus surgery (ESS), septoplasty, or both concurrently. To identify patients with allergic sensitization, serum-specific immunoglobulin E levels were measured. Nasal symptoms were evaluated with the NOSE (Nasal Obstruction Symptoms Evaluation) and SNOT-20 (Sino-Nasal Outcome Test-20) and via visual analog scale (VAS) scores. Results In the ESS group (n = 34), the general nasal symptom score evaluated by the SNOT-20 showed significantly greater improvement in the xylitol group versus the saline group ( P = .022). VAS symptom scores for sneezing ( P = .003), headache ( P = .02), and facial pain ( P = .037) were also more improved in the xylitol group. In the septoplasty group (n = 39), the VAS score for nasal stuffiness showed a significantly greater improvement in the xylitol group when compared with the saline irrigation group ( P = .001). Among the patients with allergic sensitization (n = 31), rhinorrhea symptoms improved significantly more in the xylitol group than in the saline group ( P = .024). The preference survey showed that more than half of the patients in each surgical group preferred xylitol irrigation. Conclusion We found that xylitol nasal irrigation was useful in postoperative ESS and septoplasty care. For patients with allergic sensitization, rhinorrhea showed greater improvement in the xylitol group than in the saline group.

AB - Objective To evaluate whether transoral robotic surgery (TORS) is a suitable treatment approach for patients diagnosed with tonsillar carcinoma after a standard palatine tonsillectomy. Study Design Retrospective cohort study. Setting Tertiary care medical center. Subjects and Methods Patients who underwent TORS at the University of Washington from 2010 to 2017 (n = 150) were identified. All patients who were diagnosed with tonsillar carcinoma following a nononcologic tonsillectomy and subsequently underwent TORS radical tonsillectomy were included (n = 14). Tumor stage-matched subjects (n = 44) were included who did not undergo standard tonsillectomy prior to TORS. Our primary outcome was final margin status. Secondary outcomes were presence of residual tumor, receipt and dose of postoperative adjuvant therapy, disease-free survival (DFS), and disease-specific survival. Patients with <6 months of follow-up following definitive treatment were excluded from survival analyses. Results Final margin status was clear in all subjects. Residual tumor was not identified in 13 of 14 (92.9%) prior tonsillectomy subjects following TORS radical tonsillectomy. Seven of 14 (50%) prior-tonsillectomy subjects and 12 of 44 (27.3%) TORS-matched subjects did not require adjuvant therapy due to favorable pathology. Among subjects who received post-TORS radiation therapy (RT) at our institution, RT dose reduction was achieved in 3 of 4 (75%) prior-tonsillectomy subjects and 21 of 24 (87.5%) TORS matched subjects. Ten of 14 (71.4%) prior-tonsillectomy subjects and 31 of 44 (70.5%) TORS-matched subjects avoided post-TORS chemotherapy. DFS was not significantly different ( P = .87) between prior-tonsillectomy and TORS-matched groups, and no subjects died of related disease. Conclusions Patients diagnosed with tonsillar carcinoma following a prior nononcologic standard palatine tonsillectomy are suitable candidates for revision surgery with TORS radical tonsillectomy. PMID- 30274542 TI - Measurement of bend sprinting kinematics with three-dimensional motion capture: a test-retest reliability study. AB - Sprint velocity decreases on the bend when compared with the straight, therefore understanding technique during bend sprinting could have important implications for aiding race performance. Few bend sprinting studies have used optoelectronic cameras to investigate kinematic variables. Limited published evidence regarding the reliability of marker sets in conditions representative of elite bend sprinting makes model selection difficult. Therefore, a test-retest protocol was conducted to establish the reliability and minimum detectable difference of a lower limb and trunk marker set during bend sprinting (radius: 36.5 m). Six participants completed five, 60 m trials at maximum effort, with data collected at 38-45 m. This was repeated 2-7 days later. Spatio-temporal (e.g., contact time) and kinematic variables (e.g., peak joint angles) were evaluated. Intra class correlation coefficients (ICC) were used to determine the between- and within-day reliability. Between-day reliability (ICC 3, k) was fair to excellent for all variables. Compared to between-day, within-day reliability demonstrated stronger agreement for the majority of variables. Thus, same-day data collection is preferable. It has been established that the marker set is reliable for future use. In addition, the minimal detectable difference was calculated which serves as useful reference for future research in bend sprinting. PMID- 30274543 TI - Reaction time and muscle activation patterns in elite and novice athletes performing a taekwondo kick. AB - Fractionated reaction time can be used to determine distinct epochs known as pre motor, response and movement times (MTs) of a reaction time task. The purpose of this study was to compare elite and novice athletes performing a taekwondo kick in terms of the fractionated reaction time and electromyography (EMG) activation patterns of the muscles of the striking lower limb and the lower back. We hypothesised that the pre-motor time, response time (RT) and MT would be the shorter for elite athletes compared to novices. We collected data on 13 elite and 10 novice athletes when performing a roundhouse kick. The experiment included EMG electrodes placed on five low back and lower extremity muscles and an electrogoniometer placed on the kicking knee. We found that pre-motor time was shorter and the RT was longer for elite athletes than novice athletes. Moreover, the integrated EMG of the main knee extensor does not differ between groups though other leg and trunk muscles do. The results allow coaches and teachers to understand this particular taekwondo kicking movement which could ultimately improve the technique in order to establish training and teaching goals. PMID- 30274544 TI - Human Papillomavirus-Associated Oropharyngeal Cancer: Patterns of Nodal Disease. AB - Objective To characterize patterns of neck lymph node (LN) metastases in human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma, represented by p16 positivity (p16+OPSCC). Study Design Case series with chart review. Setting Tertiary care center. Subjects and Methods Neck dissection (ND) specimens of nonirradiated p16+OPSCC patients were analyzed for frequencies of clinically evident and occult LNs by neck level. Local, regional, and distant recurrences were reviewed. Results Seventy p16+OPSCC patients underwent primary site transoral robotic surgery and 82 NDs of varying levels. Metastatic pathologic LNs were found at the following frequencies: 0% (0/28) in level I, 75.6% (62/82) in level II with 57.4% (35/61) in level IIA and 13.1% (8/61) in level IIB, 22.0% (18/82) in level III, 7.0% (5/71) in level IV, and 6.3% (1/16) in level V. The level V LN was clinically evident preoperatively. Five of 21 (23.8%) elective NDs contained occult LNs, all of which were in level II and without extranodal extension. Twenty-seven (38.6%) patients underwent adjuvant radiation; 19 (27.1%) patients underwent adjuvant chemoradiation. With a mean follow-up of 29 months, 3 patients had developed recurrences, with all but 1 patient still alive. All patients who recurred had refused at least a component of indicated adjuvant treatment. Conclusions For p16+OPSCC, therapeutic NDs should encompass any levels bearing suspicious LNs and levels IIA-B, III, and IV, while elective NDs should be performed and encompass at least levels IIA-B and III. These selective ND plans, followed by indicated adjuvant treatment, are associated with a low nodal recurrence rate. PMID- 30274545 TI - Effect of downhill running grade on lower extremity loading in female distance runners. AB - Hill running is often used as a foundational training mechanism to build strength and speed. Distance runners in particular are at an increased likelihood of encountering steep hills during training runs. There is limited research regarding downhill running, and there is no research available on the biomechanics of females specifically during downhill running. The purpose of this study was to quantify the differences in loading when running downhill at different grades compared to a level surface in female distance runners to determine the potential risk for injury. Fifteen female distance runners (age: 23.5 +/- 4.9 y), who ran 56.3 +/- 20.9 km a week participated in this study. Participants ran on a force-instrumented treadmill at 4.0 m/s for 2 min at 0%, 5%, -10%, -15%, and -20% grades, with 5 min of rest between conditions. Study findings showed increased impact forces (p < 0.001), and increased loading rates (p < 0.001) with increasing downhill grades compared to level. These results indicate a significantly greater risk of overuse injury to the lower extremity with steeper downhill grades. Individuals need to be aware of these risks to plan and implement training programmes that will increase performance while minimising injury risk. PMID- 30274546 TI - Evaluation of Acellular Bilayer Silk Fibroin Grafts for Onlay Tracheoplasty in a Rat Defect Model. AB - Objective To assess the efficacy of acellular bilayer silk fibroin (BLSF) grafts to repair full-thickness tracheal defects and to compare the performance with conventional porcine small intestinal submucosa (SIS) implants. Study Design A prospective controlled animal trial in a rat model of onlay tracheoplasty. Setting Pediatric medical center. Subjects and Methods Tracheal reconstruction of adult Sprague-Dawley rats was performed with BLSF (n = 38) or SIS (n = 32) matrices for up to 3 months of implantation. Functional evaluations of repaired conduits as well as histologic, immunohistochemical, and histomorphometric analyses of neotissues were assessed. Results Prior to scheduled euthanasia, survival rates of rats receiving BLSF or SIS grafts were >=94%, with no clinical signs of airway obstruction observed over the course of the study. Micro-computed tomography analysis revealed that the mean percentage of stenosis was <20% in both implant groups. BLSF and SIS grafts supported formation of pseudostratified ciliated columnar epithelium by 1 week postoperatively; however, each matrix failed to promote de novo chondrogenesis by 3 months following repair. Conclusions BLSF scaffolds can be used for reconstruction of rat tracheal patch defects with functional outcomes comparable to those of SIS matrices.

AB - In this review, I present the main highlights of my works in the development of bioelectrocatalysis, which can be used in widespread applications, particularly for the design of biosensor and biofuel cells. In particular, I focus on research progress made in two key bioelectrocatalytic reactions: glucose oxidation by flavin adenine dinucleotide-dependent glucose dehydrogenase and oxygen reduction by bilirubin oxidase. I demonstrate the fundamental principles of bioelectrocatalysis and the requirements for enhancing the catalytic performance, including the choice of a mediator of redox reactions, immobilization, and electrode materials. These methods can allow for achieving control of the bioelectrocatalytic reaction, thereby overcoming obstacles toward their industrial applications.

The pathophysiology of peripheral vestibular symptoms following head injury without temporal bone (TB) fracture, however, is not well understood. Herein, we investigate the histopathology of the peripheral vestibular system of patients who sustained head injury without a TB fracture. Study Design Otopathology study. Setting Otopathology laboratory. Subjects and Methods TB of subjects with a history of head injury without TB fractures were included and evaluated by light microscopy. Specimens were assessed for qualitative and quantitative characteristics, such as number of Scarpa's ganglion cells in the superior and inferior vestibular nerves, vestibular hair cell and/or dendrite degeneration in vestibular end organs, presence of vestibular hydrops, and obstruction of the endolymphatic duct. Results Five cases (n = 5 TBs) had evidence of vestibular pathology. There was a decrease of 48.6% (range, 40%-59%) in the mean count of Scarpa's ganglion cells as compared with that of normative historical age-matched controls. Moderate to severe degeneration of the vestibular membranous labyrinth was identified in the posterior, superior, and lateral canals in several cases (50%, n = 4 TBs). The maculae utriculi and sacculi showed mild to severe degeneration in 2 cases. Additional findings include vestibular hydrops (25%, n = 2 TBs) and blockage of the endolymphatic duct (n = 1 TB). Conclusions Otopathologic analysis of patients with a history of head injury without TB fracture demonstrated peripheral vestibular otopathology. Future studies are necessary to determine if otopathology findings are directly attributable to head injury. PMID- 30274549 TI - Effect of exercise order with barbell and machine modalities on upper body volume load and myoelectric activity. AB - The purpose of this study was to investigate the influence of exercise order on volume load (VL) and myoelectric activation (EMG) during the bench press (BP), military press (MP) and close-grip bench press (CGBP) exercises executed with a barbell and Smith machine. Twelve men experienced in resistance training performed four different exercise sessions in randomised order. Each session consisted of four sets of a given exercise order: O1 = CGBP + MP + BP with barbell; O2 = inverse O1 with barbell, O3 = same O1 with Smith Machine; O4 = same O2 with Smith machine. EMG was assessed for the Clavicular head pectoralis major (PMC), anterior deltoid (AD), triceps brachii long head (TBLH) and biceps brachii (BB). Results showed that VL in BP was affected by exercise order, independent of the mode (p < 0.05). However, the CGBP showed higher VL in O1. Moreover, when the BP was positioned last in the sequence (O1 and O3), myoelectric activity was higher for PMC, AD and TBLH (p < 0.05). Findings were similar in the CGBP (PMC and TBLH), but for the AD (Smith machine > barbell, p < 0.05). Therefore, it appears that the order and modes of exercises influence both volume load and myoelectric activation patterns during multiple set of resistance training.

AB - Goaltenders in the sport of ice hockey are at high risk for concussions from falls to the ice, player collisions and puck impacts. However, current methods used to certify helmets only consider head accelerations for drop tests which may not describe all common injury mechanisms relating to concussion. The purpose of this study was to describe the characteristics of 3 events associated with concussions for ice hockey goaltenders. A helmeted medium National Operating Committee on Standards for Athletic Equipment (NOCSAE) headform was impacted under conditions representing 3 injury events. Three impact locations' velocities were selected for each event based on video analysis of real-world concussive events. Peak resultant linear acceleration, rotational acceleration and rotational velocity of the headform were measured. The University College Dublin Brain Trauma Model (UCDBTM) was used to calculate maximum principal strain (MPS) and von Mises stress in the cerebrum. Each impact event produced a unique dynamic response and brain stress and strain values. This demonstrates that a single impact event (i.e. falls) cannot adequately describe all impact events. As a result, impact protocols which assess multiple impact events such as the protocol described in this study should be used to evaluate ice hockey goaltender masks. PMID- 30274551 TI - Engineering of Corynebacterium glutamicum as a prototrophic pyruvate-producing strain: Characterization of a ramA-deficient mutant and its application for metabolic engineering. AB - To construct a prototrophic Corynebacterium glutamicum strain that efficiently produces pyruvate from glucose, the effects of inactivating RamA, a global regulator responsible for activating the oxidative tricarboxylic acid (TCA) cycle, on glucose metabolism were investigated. DeltaramA showed an increased specific glucose consumption rate, decreased growth, comparable pyruvate production, higher formation of lactate and acetate, and lower accumulation of succinate and 2-oxoglutarate compared to the wild type. A significant decrease in pyruvate dehydrogenase complex activity was observed for DeltaramA, indicating reduced carbon flow to the TCA cycle in DeltaramA. To create an efficient pyruvate producer, the ramA gene was deleted in a strain lacking the genes involved in all known lactate- and acetate-producing pathways. The resulting mutant produced 161 mM pyruvate from 222 mM glucose, which was significantly higher than that of the parent (89.3 mM; 1.80-fold). PMID- 30274552 TI - Knee joint coordination during single-leg landing in different directions. AB - Knee joint coordination during jump landing in different directions is an important consideration for injury prevention. The aim of the current study was to investigate knee and hip kinematics on the non-dominant and dominant limbs during landing. A total of 19 female volleyball athletes performed single-leg jump-landing tests in four directions; forward (0 degrees ), diagonal (30 degrees and 60 degrees ) and lateral (90 degrees ) directions. Kinematic and ground reaction force data were collected using a 10-camera Vicon system and an AMTI force plate. Knee and hip joint angles, and knee angular velocities were calculated using a lower extremity model in Visual3D. A two factor repeated measures ANOVA was performed to explore limb dominance and jump direction. Significant differences were seen between the jump directions for; angular velocity at initial contact (p < 0.001), angular velocity at peak vertical ground reaction force (p < 0.001), and knee flexion excursion (p = 0.016). Knee coordination was observed to be poorer in the early phase of velocity-angle plot during landing in lateral direction compared to forward and diagonal directions. The non-dominant limb seemed to have better coordination than the dominant limb during multi-direction jump landing. Therefore, dominant limbs appear to be at a higher injury risk than non-dominant limbs. PMID- 30274553 TI - Strong development of research based on national quality registries in Sweden. AB - The aim of the present paper is to describe how the use of national quality registries (NQRs) for research has evolved over the past decade in Sweden. All Swedish NQRs have reported their scientific activity (publications per year in peer-reviewed scientific journals) to the Swedish Association of Local Authorities and Regions since 2009, and the present report is based on available data from 2009-2016. The yearly number of publications of the 69 registries active in 2009 has increased from 121 to 496 in 2016. Seventeen of these registries published more than 10 papers in 2016; however, 12 NQRs did not publish any papers in 2016. An additional 77 papers were published in 2016 by the 34 NQRs started after 2009. In summary, there has been a strong development of quality registry-based research in Sweden over the last decade. However, there is still room for further increase of the use of research based on NQRs in Sweden. PMID- 30274554 TI - Depressive Disorder in Thyroid Cancer Patients after Thyroidectomy: A Longitudinal Follow-up Study Using a National Cohort. AB - Objective The present study compared the frequency of depressive disorder in patients with thyroid cancer who had undergone thyroidectomy with the frequency in control individuals. Study Design Retrospective population-based cohort study. Setting This study used data from the Korean Health Insurance Review and Assessment Service-National Sample Cohort. Subject and Methods A total of 3609 participants with thyroid cancer who had undergone thyroidectomy between 2003 and 2011 were enrolled in this study and matched 1:4 with 14,436 control participants by age, sex, income, and region of residence. The cumulative incidence of postoperative depressive disorder was evaluated over a period of 10 years after the thyroidectomies and compared with the incidence in controls. Depressive disorder was diagnosed by a psychiatrist. Results The incidence of depressive disorder was significantly higher in the thyroid cancer with thyroidectomy group than in the controls up to postoperative year 1. A subgroup analysis showed the same higher incidence of depressive disorder in the thyroid cancer group than controls for up to 1 year after operations in young adult (<=44 years old), female, urban, and low-income groups. However, the incidence was elevated only in the year of the thyroidectomies themselves in middle-aged and older, rural, and high-income groups. Conclusion Patients with thyroid cancer who undergo thyroidectomy have depressive disorder more frequently than normal controls. However, the frequency of depressive disorder after thyroidectomy recovers in a shorter period in middle-aged or older, high-income, and rural-dwelling patients, compared to younger, low-income, and urban-dwelling patients. PMID- 30274555 TI - Inventory of chytrid diversity in two temporary forest ponds using a multiphasic approach. AB - Food webs in temporary forest ponds are driven by decomposition of terrestrial inputs. Chytrid fungi are important components of the fungal community, degrading leaf litter in streams reliant on terrestrial inputs and in lake ecosystems where they may stabilize the food web. However, little is known about chytrid fungi in temporary forest ponds. We inventoried the chytrid diversity present in two temporary forest ponds via light microscopy of baited samples and ion semiconductor (Ion Torrent) sequencing of environmental DNA. We quantified trends of chytrid alpha and beta diversity as a function of spatial and temporal factors. A total of 59 chytrid taxa were detected throughout the study. Beta diversity exhibited variation across the sampled months for both the entire fungal community as well as for chytrids alone. Shifts in community composition were also apparent, although diversity metrics and composition patterns did not meet adjusted P values. The results of this study highlight the diversity of chytrid fungi in temporary forest ponds and the need for further studies on the spatial and temporal dynamics of chytrid species. PMID- 30274556 TI - Intellectual disability in Irish prisoners: systematic review of prevalence. AB - Purpose While individuals with an intellectual disability form a significant minority in the worldwide prison population, their healthcare needs require specialist attention. In Ireland, services for prisoners with intellectual disabilities need development. However, there is little substantive data estimating the prevalence of intellectual disabilities within the Irish prison system. The paper aims to discuss these issues. Design/methodology/approach The authors systematically review published data relating to the prevalence of intellectual disabilities in prisons in the Republic of Ireland. The authors searched four databases, governmental websites and corresponded with experts. Findings Little published data were elicited from searches except for one nationwide cross-sectional survey which reflected a higher prevalence than reported in international studies. Studies from forensic mental health populations are narrated to contextualise findings. Originality/value This study found that there is little data to accurately estimate the prevalence of intellectual disabilities in the Irish prison system and the limited data available suggests that this is likely to be higher than international estimates. The authors highlight the need for further research to accurately estimate prevalence in this jurisdiction, alongside the need to develop screening and care pathways for prisoners with an intellectual disability. PMID- 30274557 TI - Development of healthcare facility standards for Thai female inmates. AB - Purpose The purpose of this paper is to develop and evaluate the Standards of Healthcare Facility for Thai Female Inmates (SHF-TFI) through healthcare service improvement. Design/methodology/approach This research and quality improvement project was comprised of three phases. Surveying healthcare facilities and in depth interviews with female inmates as well as prison nurses were employed in Phase I. Expert reviews and public hearing meetings were used for developing the SHF-TFI in Phase II. Satisfaction questionnaires, focus group interviews of the female inmates, and in-depth interviews with nurses and prison wardens were utilized to evaluate feasibility and effectiveness of SHF-TFI implementation in Phase III. Findings The SHF-TFI was elaborated in order to be more specific to the context of the correctional institutes and correspond with healthcare as to the needs of female inmates. It was divided into three main aspects: administrative standards, health service standards and outcome standards. After implementation, nurses reflected on the feasibility and benefits of the SHF-TFI on the organizations, inmates and nurses. The female inmates perceived remarkable improvement in the healthcare services including physical activity promotion and screening programs for non-communicable diseases, the physical environment and sufficiency of medical equipment. Moreover, the pregnant inmates and incarcerated mothers with children shared their views on better antenatal and child developmental care, as well as availability of baby supplies. Originality/value The findings support the feasibility and effectiveness of the SHF-TFI for quality care improvement and applicability of the Bangkok Rules in women's correctional institutes. PMID- 30274558 TI - Drug injection within prison in Kyrgyzstan: elevated HIV risk and implications for scaling up opioid agonist treatments. AB - Purpose Within-prison drug injection (WPDI) is a particularly high HIV risk behavior, yet has not been examined in Central Asia. A unique opportunity in Kyrgyzstan where both methadone maintenance treatment (MMT) and needle-syringe programs (NSP) exist allowed further inquiry into this high risk environment. The paper aims to discuss these issues. Design/methodology/approach A randomly selected, nationally representative sample of prisoners within six months of release in Kyrgyzstan completed biobehavioral surveys. Inquiry about drug injection focused on three time periods (lifetime, 30 days before incarceration and during incarceration). The authors performed bivariate and multivariable generalized linear modeling with quasi-binomial distribution and logit link to determine the independent correlates of current WPDI. Findings Of 368 prisoners (13 percent women), 109 (35 percent) had ever injected drugs, with most (86 percent) reporting WPDI. Among those reporting WPDI, 34.8 percent had initiated drug injection within prison. Despite nearly all (95 percent) drug injectors having initiated MMT previously, current MMT use was low with coverage only reaching 11 percent of drug injectors. Two factors were independently correlated with WPDI: drug injection in the 30 days before the current incarceration (AOR=12.6; 95%CI=3.3-48.9) and having hepatitis C infection (AOR: 10.1; 95%CI=2.5 41.0). Originality/value This study is the only examination of WPDI from a nationally representative survey of prisoners where both MMT and NSP are available in prisons and in a region where HIV incidence and mortality are increasing. WPDI levels were extraordinarily high in the presence of low uptake of prison-based MMT. Interventions that effectively scale-up MMT are urgently required as well as an investigation of the environmental factors that contribute to the interplay between MMT and WPDI. PMID- 30274559 TI - The profile of prisoners with tuberculosis in Japan. AB - Purpose Although globally, prisoners are considered one of the vulnerable groups to tuberculosis (TB), little is known about the situation of TB in prison setting in Japan. The purpose of this paper is to examine the characteristics of TB among prisoners in Japan. Design/methodology/approach Records of TB patients from one medical prison were analyzed in terms of general demographic characteristics, clinical manifestations, risk factors and delay in diagnosis and in initiating treatment, and compared with data from the national TB surveillance and other published data on health of inmates, where appropriate. Continuous variables were compared using student independent samples t-test. Proportions were compared using chi2 or Fisher exact test as appropriate. Kaplan-Meier survival analysis was conducted to determine the time from entry to prison institution to diagnosis of TB. Findings A total of 49 patients were analyzed. The mean age was 49.5 (+/ 14.3) and 69.4 percent were males. Being unemployed and homeless prior to incarceration, and several co-morbidities were potential risk factors for TB ( p<0.01). Analysis of diagnosis and treatment delay showed that 16.1 percent of smear positive patients took more than a week to be placed on treatment after being diagnosed of TB. Approximately 50 percent of the patients were diagnosed within four months of entering the prison institution. Practical implications Several potential risk factors identified suggest the need to strengthen screening for specific sub-groups within the prison population, such as those with poor socio-economic status and co-morbidities, as well as to consider the possible role of systematic screening for latent TB infection. Originality/value This study presents some important data to help understand the profile of TB patients in prisons in Japan, as well as showing that a detailed epidemiological analysis of existing records can provide useful insight. PMID- 30274560 TI - Prisoner health status at three rural Haitian prisons. AB - Purpose Little is known about the health status of prisoners in low-income countries. In Haiti, prisons typically lack adequate medical care, clean water and food, though some prisoners receive additional food from visitors. The purpose of this paper is to characterize the physical and mental health of Haitian prisoners in three select prisons and examine the effects of having visitors and length of detention on health status. The authors hypothesized that prisoners with more visitors and shorter detention times would have better overall health status. Design/methodology/approach The authors conducted a cross sectional study of 290 male inmates in three regional prisons in Haiti. Data were collected on prisoners' sociodemographic characteristics, number of visitors, length of detention, body mass index (BMI), self-reported physical and mental health status, and food insecurity. Findings Overall, prisoners at all three prisons had poor health outcomes. Prisoners with more visitors were significantly less likely to be underweight and more likely to have a higher BMI, better self reported physical function and lower levels of food insecurity. The length of incarceration was negatively associated with physical function and self-rated health, but positively associated with BMI. These results suggest that prisoners who do not receive supplemental food from visitors are at increased risk for food insecurity and poor nutritional and physical health status. Originality/value These findings demonstrate the importance of supplemental food from visitors in stabilizing prisoner health in Haiti and emphasize the need for the provision of adequate nutrition to all prisoners. This study also suggests that policies that reduce incarceration times could improve health status among prisoners. PMID- 30274561 TI - Socio-demographic characteristics as correlates of psychological distress. AB - Purpose The purpose of this paper is to assess the level of psychological distress of offenders newly brought into prison custody in a Nigerian prison and investigate the relationship with socio-demographic and penal characteristics. Design/methodology/approach A cross-sectional study involving 236 new prison entrants who were assessed for psychological distress using the 12-item General Health Questionnaire (GHQ-12) and the Hospital Anxiety and Depression Scale (HADS). Findings A total of 267 prison inmates were newly brought to prison custody over a three-month period. Out of this, 236 (88.4 per cent) of them participated in the study. Majority of the inmates were males 225 (95.3 per cent), awaiting-trial inmates 208 (88.1 per cent), single 144 (61 per cent), Christian 224 (94.9 per cent), first time offenders 218 (92.4 per cent) and charged with violent offences 136 (57.6 per cent). Majority of the inmates scored above cut-off points on the GHQ-12 and the HADS. In total, 157 (66.5 per cent) on HADS anxiety subscale, 201 (85.2 per cent) on HADS depression subscale and 199 (84.3 per cent) on GHQ-12. Significant relationship was observed between GHQ-12 "caseness", prison category and type of offence. Prison situation and type of offence were significantly associated with HADS depression subscale, whereas age was associated with HADS anxiety subscale. Research limitations/implications Some limitations were encountered in the course of the study. First, the study relied on self-report questionnaires for collection of data. Second, information given by the respondents could neither be corroborated by family members, who were not present during the interview, nor by the officers and men of the Nigeria Prisons Service, who knew little or nothing about the respondents. Participants in this study had spent maximum of three days in prison during the interview, thus certain levels of distress within three days after incarceration may not entail "caseness" in the sense of the presence of a psychiatric disorder. Therefore assessment over a longer period is needed. Practical implications Screening prison inmates on reception into prison custody provides a vista of opportunity to identify mental health problems and socio-demographic and forensic correlates of psychological distress among new entrants into prison custody. This will facilitate early identification and management of prison inmates with health needs. Health screening on reception will also help in identifying the various penal or forensic characteristics of prison inmates, which will be put into consideration during selection of appropriate rehabilitation and reformation activities that best fit a particular prison inmate. Early screening of prison inmates upon reception in the prison will also help in identifying prison inmates who have high risk of suicide and self-harm, thus preventing cases of death that may arise as a result of these mental health problems. Findings from this study will also enrich the body of knowledge on mental health problems of prison inmates entering the prison; this will also help the criminal justice system in decision making, especially with emphasis on psychological evaluation of prison inmates before dispensing judgment. On the part of the prison authority, the prison inmates identified to have psychological distress and some forensic characteristics can be properly classified, and kept in cells that will not aggravate their distress. Finally, this is the first study of prison inmates on reception into Enugu Maximum Security Prison, Enugu State Nigeria. The implication of this is that findings from this research will form a baseline on which further research on prison inmates upon reception in the prison can be conducted. Originality/value This study demonstrated that prison inmates are faced with high level of psychological distress during their early days in prison, and that some socio-demographic and forensic variables had significant association with psychological distress as itemised in Tables III and IV . Therefore, screening new inmates on prison reception will help in early identification and treatment of vulnerable groups. This will also help in proper classification and allocation into appropriate cells of prison inmates by the prison authority. PMID- 30274562 TI - Modeling the role of fomites in a norovirus outbreak. AB - Norovirus accounts for a large portion of the gastroenteritis disease burden, and outbreaks have occurred in a wide variety of environments. Understanding the role of fomites in norovirus transmission will inform behavioral interventions, such as hand washing and surface disinfection. The purpose of this study was to estimate the contribution of fomite-mediated exposures to infection and illness risks in outbreaks. A simulation model in discrete time that accounted for hand to-porous surfaces, hand-to-nonporous surfaces, hand-to-mouth, -eyes, -nose, and hand washing events was used to predict 17 hr of simulated human behavior. Norovirus concentrations originated from monitoring contamination levels on surfaces during an outbreak on houseboats. To predict infection risk, two dose response models (fractional Poisson and 2F1 hypergeometric) were used to capture a range of infection risks. A triangular distribution describing the conditional probability of illness given an infection was multiplied by modeled infection risks to estimate illness risks. Infection risks ranged from 70.22% to 72.20% and illness risks ranged from 21.29% to 70.36%. A sensitivity analysis revealed that the number of hand-to-mouth contacts and the number of hand washing events had strong relationships with model-predicted doses. Predicted infection risks ranged from 21.29% to 70.36%, overlapping with leisure setting and environmental attack rates reported in the literature. In the outbreak associated with the viral concentrations used in this study, attack rates ranged from 50% to 86%. This model suggests that fomites may have accounted for 25% to 82% of illnesses in this outbreak. Fomite-mediated exposures may contribute to a large portion of total attack rates in outbreaks involving multiple transmission modes. The findings of this study reinforce the importance of frequent fomite cleaning and hand washing, especially when ill persons are present. PMID- 30274563 TI - Development and psychometric testing of an instrument to measure women's perceptions of unplanned pregnancy. AB - A woman's decision to continue or terminate an unplanned pregnancy is affected by a broad range of contextual and cognitive factors. The identification of women's perceptions of unplanned pregnancy is crucial for health care providers to be able to offer supportive care and counselling. The aim of this study was to develop an instrument to accurately measure women's perceptions of unplanned pregnancy: the Women's Perceptions of Unplanned Pregnancy Questionnaire. The instrument was developed using a methodological framework guided by Waltz et al. (2010). A conceptual model of the designed instrument emerged from the qualitative study using a content analysis approach conducted in Tabriz, Iran. Participants were recruited using convenience sampling method between June 2016 and July 2017. Participants were a sample of married Iranian women between the ages of 15 and 49 who had experienced an unplanned pregnancy, either unwanted or mistimed, within the last 3 months. Women with an established diagnosis of a psychological disorder were excluded from the study. The psychometric properties of the instrument were assessed using face, content, concurrent and construct validations. To evaluate face validity, qualitative and quantitative (item impact score) methods were used. The content validity was assessed by fifteen panel experts. In addition, concurrent validity of the designed instrument was tested using the Persian version of the Cambridge Worry Scale and the Spielberger State Trait Anxiety Inventory. The construct validity was calculated by using the exploratory factor analysis method. Data were collected from questionnaires completed by 310 eligible women. Analysis of the data using exploratory factor analysis yielded 31 items in a unique six-factor structure. The instrument was found to have high internal consistency (Cronbach's alpha=0.88) and adequate reliability (Intraclass Correlation Coefficient=0.89). A clearer understanding of women's perceptions of unplanned pregnancy may enhance reproductive services and interventions. PMID- 30274564 TI - Impact of prenatal and postnatal maternal environment on nephron endowment, renal function and blood pressure in the Lewis polycystic kidney rat. AB - Maternal insufficiency during fetal development can have long-lasting effects on the offspring, most notably on nephron endowment. In polycystic kidney disease (PKD), variability in severity of disease is observed and maternal environment may be a modifying factor. In this study, we first established that in a rodent model of PKD, the Lewis polycystic kidney (LPK) rat's nephron numbers are 25% lower compared with wildtype animals. We then investigated the effects of prenatal and postnatal maternal environment on phenotype and nephron number. LPK pups born from and raised by homozygous LPK dams (control) were compared with LPK pups cross-fostered onto heterozygous LPK dams to improve postnatal environment; with LPK pups born from and raised by heterozygous LPK dams to improve both prenatal and postnatal environment and with LPK pups born from and raised by Wistar Kyoto-LPK heterozygous dams to improve both prenatal and postnatal environment on a different genetic background. Improvement in both prenatal and postnatal environment improved postnatal growth, renal function and reduced blood pressure, most notably in animals with different genetic background. Animals with improved postnatal environment only showed improved growth and blood pressure, but to a lesser extent. All intervention groups showed increased nephron number compared with control LPK. In summary, prenatal and postnatal environment had significant effect in delaying progression and reducing severity of PKD, including nephron endowment. PMID- 30274565 TI - Relative validity of brief-type self-administered diet history questionnaire among very old Japanese aged 80 years or older. AB - OBJECTIVE: Dietary questionnaires for assessing dietary intakes among populations of individuals aged 80 years or older (the very old) are very limited. We examined the relative validity of forty-three nutrients and twenty-seven food groups estimated by a brief-type self-administered diet history questionnaire (BDHQ) targeting very old Japanese, using semi-weighed dietary records (DR) as a reference. DESIGN: Between June and August 2012 and between June 2015 and February 2016, a three-day non-consecutive DR (at two-week intervals) and a BDHQ were completed. SETTING: Tokyo, the capital prefecture of Japan. SUBJECTS: Eighty very old Japanese (thirty-six men and forty-four women) aged 82-94 years. RESULTS: The median intakes of 40-70 % of the crude and energy-adjusted nutrients estimated by the BDHQ were significantly different from those estimated by the DR. The median Spearman's correlation coefficient of nutrient intakes between the BDHQ and the DR was 0.39-0.46. About half (48-56 %) of the food groups were significantly different in terms of the median intakes estimated by the BDHQ and the DR in crude and energy-adjusted values. The median Spearman's correlation coefficient between the BDHQ and the DR was 0.45-0.48. CONCLUSIONS: Acceptable Spearman's correlations (>=0.3) were obtained for many dietary intakes among the very old Japanese population. The BDHQ is a good candidate for epidemiological studies among very old Japanese, although, for some nutrients and food groups, the difficulty of estimating accurate median intakes is one of the limitations for the tool. Further efforts to enhance the validity of the BDHQ for very old populations are needed. PMID- 30274566 TI - Mental illness in primary care: a narrative review of patient, GP and population factors that affect prescribing rates. AB - BACKGROUND: Mental illness poses a large and growing disease burden worldwide. Its management is increasingly provided by primary care. The prescribing of psychotropic drugs in general practice has risen in recent decades, and variation in prescribing rates has been identified by a number of studies. It is unclear which factors lead to this variation.AimTo describe the variables that cause variation in prescribing rates for psychotropic drugs between general practices. METHODS: A narrative review was conducted in January 2018 by searching electronic databases using the PRISMA statement. Studies investigating causal factors for variation in psychotropic prescribing between at least two general practice sites were eligible for inclusion. RESULTS: Ten studies met the inclusion criteria. Prescribing rates varied considerably between practices. Positive associations were found for many variables, including social deprivation, ethnicity, patient age and gender, urban location, co-morbidities, chronic diseases and GP demographics. However studies show conflicting findings, and no single regression model explained more than 57% of the variation in prescribing rates.DiscussionThere is no consensus on the factors that most predict prescribing rates. Most research was conducted in countries with central electronic databases, such as the United Kingdom; it is unclear whether these findings apply in other healthcare systems. More research is needed to determine the variables that explain prescribing rates for psychotropic medications. PMID- 30274567 TI - Evaluation of the TRANSIA(r)PLATE Staphylococcal Enterotoxins Kit for the Detection of Staphylococcal Enterotoxins in Selected Foods. AB - The TRANSIA(r) PLATE Staphylococcal Enterotoxins enzyme immunoassay (EIA) was validated according to AOAC INTERNATIONAL guidelines for validating qualitative binary chemistry and microbiological methods. Five food matrixes were analyzed to determine the probability of detection (POD) for staphylococcal enterotoxins (SE), including SEA, SEB, SEC1, SEC2, SEC3, SED, and SEE, by the TRANSIA PLATE Staphylococcal Enterotoxins EIA. The food matrixes tested were food types implicated in staphylococcal enterotoxin outbreaks and included raw milk cheese, liquid infant formula, eclairs, ready-to-eat ham, and canned mushrooms. Cheese and infant formula were tested with and without dialysis/concentration. The infant formula was also tested by an independent laboratory. Each food matrix was inoculated with specific toxins at low levels to yield fractional recoveries (0.015-0.20 ng/g of food) for POD analysis. One hundred percent recovery was achieved at concentrations ranging from <0.10 ng/g to 0.25 ng/g of toxin in the various food matrixes. At the same time, 50 Staphylococcus aureus strains known to produce toxins and 30 non-toxin producing bacteria (including 22 Staphylococcus strains) were grown and tested. All the SE toxin-producing strains yielded positive results and all of the exclusivity strains were negative. Robustness studies showed that changes in sample volume, sample pH, and EIA assay temperature had no significant effect on performance. Stability studies showed that kits stored for 12+ months performed as well as newly made kits. This assay has been approved as a Performance Tested MethodSM. PMID- 30274568 TI - Baseline characteristics of gay and bisexual men in a HIV pre-exposure prophylaxis demonstration project with equity quotas in Auckland, New Zealand. AB - Background: In New Zealand, pre-exposure prophylaxis (PrEP) should target gay and bisexual men (GBM), and equity is an important principle. Baseline characteristics of GBM offered PrEP in a demonstration project with an enrolment quota of 50% non-Europeans are described. Methods: An open-label, single-arm treatment evaluation study design ('NZPrEP') was used. The settings were four publicly funded sexual health clinics in Auckland in 2017. The study population was 150 GBM recruited from clinics, community sources and social media. Participants self-completed an online questionnaire about PrEP awareness, attitudes and sexual risk behaviour in the last 3 months. Baseline characteristics are described and examined to determine whether these were associated with PrEP initiation status (self-referral vs doctor/nurse recommendation). Results: In total, 150 GBM of whom half (52%) were non-European, including 21.3% Maori, 19.3% Asian and 8.7% Pacific, were enrolled into the study. Two-thirds (65.3%) self-referred for PrEP and one-third (34.7%) were recommended PrEP by the doctor/nurse. Participants reported a high number of male condomless receptive anal intercourse partners (MenAICLR) (median 3, range 0-50), with 10% reporting 10 or more MenAICLR and 45.3% reporting group sex. In the previous year, 65.3% had a sexually transmissible infection (STI); 18% had rectal chlamydia or gonorrhoea at enrolment. Almost half (47.7%) had recently used drugs with sex, including 8.1% who used methamphetamine. Participants recommended PrEP had lower education, lived less centrally and had a higher STI prevalence than PrEP self-referrers, but their risk behaviour was similar. Conclusions: Early PrEP adopters in New Zealand have high HIV risk. Demonstration projects should consider equity mechanisms so that minorities can participate meaningfully. PMID- 30274569 TI - ?

Thus, a reliable monitoring of blood pressure is desirable. New clinical studies indicate, that monitoring of middle arterial pressure with continuous non-invasive monitoring during stable haemodynamic conditioning provides accurate changes in blood pressure. The potential of continuous non invasive monitoring is promising, but not fully developed. PMID- 30274571 TI - [Use of compression stockings during flights]. AB - Flights longer than four hours pose a risk of venous thromboembolism in the general population, and the risk increases when additional risk factors are present. Compression stockings have proven beneficial on deep as well as superficial vein thrombosis and oedema during long-haul flights, without causing side effects or discomfort. However, no data exist for flights shorter than four hours. Passengers can use compression stockings as general prophylaxis, and this should be recommended based on an assessment of endogenous risk factors and the duration of the travel.

AB - We present a case report of a ten-month-old boy, who was referred due to deviating growth and recurrent respiratory tract infections. Computed tomography of the thorax showed two large, cystic components in the mediastinum. He underwent surgical removal of the cysts. Pathological examination confirmed the diagnosis lymphatic malformation. This case illustrates that intrathoracic tumors such as lymphatic malformations, although rare, should be considered in children with deviating growth curves and respiratory problems. Rather than continuous symptomatic treatment children with symptoms early in life should be prompted in further investigations.

AB - Research supports theories on valid differences between early-onset schizophrenia (EOS), which persists through life, versus late-onset schizophrenia. We differentiate between schizophrenia, late-onset schizophrenia (LOS), very late onset schizophrenia-like psychosis (VLOSLP) and paranoid psychosis in the elderly. While LOS may resemble EOS, VLOSLP may resemble neurodegenerative disorders such as Parkinson's disease and Alzheimer's disease. In this review, a treatment guideline is proposed. PMID- 30274574 TI - [Treatment limitations or discontinuation in patients with benign pulmonary diseases]. AB - The decision to limit or discontinue treatment is a difficult issue, which all physicians will face. Timely communication with information on treatment possibilities and limitations, respectful listening to patients' and informal caregivers' wishes and early palliation is recommended in a stable phase. In some situations, it is better to stop life-prolonging treatment and optimise quality of life in patients with benign pulmonary diseases. Decision on treatment limitations or discontinuation is best taken at a conference and should be based on the patient's wishes, the disease stage and progression and potential reversible components. PMID- 30274575 TI - [Allergic reactions to local anaesthetics]. AB - Local anaesthetics (LA) are frequently used, but allergy to LA is very rare. It can only be verified in about 1% of the patients referred with suspected allergy. Reactions may be due to vasovagal or toxic reactions, allergies to additives or other products used during administration. Suspicion of allergy should be investigated to rule out or confirm allergy. In case of allergy to LA, search of a safe alternative ensures the patients future ability to receive LA treatment. The investigation method depends on, whether a type I- or type IV reaction is suspected. PMID- 30274576 TI - ? PMID- 30274577 TI - ?

Data suggest that women with CUAs are at higher risk of recurrent spontaneous abortions and adverse pregnancy outcomes. It is still debated whether these women have impaired fertility. The complication rate is likely to be overrepresented and assumedly many women with CUAs have normal reproduction and uneventful pregnancies. In women with CUAs and infertility or numerous spontaneous abortions surgical treatment should be considered. PMID- 30274579 TI - [Human consciousness in health and disease]. AB - Functional neuroimaging, electroencephalography and clinical examination are essential to understand the many facets of disorders of consciousness. Yet, it is still not widely known that patients exist who are clearly conscious but unable to show it owing to complete loss of motor output, a condition which has been termed cognitive motor dissociation. In this review, the mechanisms of normal and impaired consciousness are discussed, and current theories of consciousness, as well as specific clinical signs, which are essential to discern the state of consciousness in a given patient, are highlighted. PMID- 30274580 TI - [Benign scrotal diseases]. AB - Scrotal diseases can be categorised in different ways: Are the patients young or old, or is the condition acute or chronic? Few organs are as easily accessible as scrotum. Nevertheless, it can be difficult to make a correct diagnosis especially in chronic patients. This review divides scrotal diseases in two groups: acute and non-acute diseases. Relevant diseases are described with symptoms, clinical findings and treatment.

Low health literacy is defined by difficulties related to understanding health information and ability to engage with healthcare providers. Research has explored a variety of interventions to address the issue of low literacy. This study describes that educational curricula including lessons and practicing in didactics and health literacy may improve doctors' knowledge and approach towards this group of patients and indicates that healthcare providers generally can benefit from education in health literacy.

AB - Epidermiolysis bullosa (EB) is a rare group of genetic disorders, which are characterised by bullae and erosions on skin and mucosa. This case report describes a patient, who was born at full term without any complications. Both crurae were affected by aplasia cutis. Upon birth, the newborn was wrapped in a soft blanket, and prophylactic antibiotic treatment was started along with analgesics. Large bullae were punctured with a sterile needle, and erosions were treated with non-adherent wound dressings and special bandages. Gloves and shoes were custom-made. Autosomal recessive dystrophic EB was genetically confirmed, and the child was followed regularly by an EB-team. PMID- 30274583 TI - [Examination for osteoporosis in patients with chronic obstructive pulmonary disease]. AB - Patients with chronic obstructive pulmonary disease (COPD) are at risk of developing osteoporosis, as the COPD in itself as well as continued smoking and treatment with systemic corticosteroid all increase the risk of developing osteoporosis. Other risk factors for osteoporosis are low vitamin D levels, malnutrition and physical inactivity. All patients who have risk factors in the form of severe COPD, and all patients with COPD in active treatment with systemic corticosteroid and/or other risk factors should be examined with a DEXA-scan. Treatment of osteoporosis in patients with COPD does not differ from general recommendations. PMID- 30274584 TI - ? PMID- 30274585 TI - [Treatment of heart failure in patients with reduced left- ventricular ejection fraction]. AB - Treatment of heart failure with reduced ejection fraction has undergone an enormous development over the latest three decades resulting in lower mortality. Standard treatment now includes use of angiotensin-converting-enzyme (ACE) inhibitors, beta blockers and mineralocorticoid receptor antagonists. Diuretics are still the cornerstone in the symptomatic treatment of fluid retention. Combined angiotensin II receptor blockade and neprilysin inhibition is a new treatment option instead of ACE-inhibition for selected patients. Cardiac resynchronisation therapy and prophylactic implantable cardiac defibrillators further reduce mortality. PMID- 30274586 TI - [Heart failure often accompanies diabetes mellitus]. AB - There are 320,000 diabetes patients in Denmark. Heart failure (HF) is a major cardiovascular complication to diabetes mellitus with increasing prevalence. HF occurs 2-4 times more frequently in diabetes patients, but patients may go undiagnosed for years. Diabetes patients typically suffer from diastolic dysfunction caused by myocardial hyper-trophy and "stiffness" of the left ventricle. This frequent finding has prompted the term "diabetic cardiomyopathy". Echocardiography is a key examination in diagnosing HF and may be warranted to a greater degree in diabetes patients at particular risk. PMID- 30274587 TI - [Rehabilitation and palliative care in cardiovascular diseases in Denmark]. AB - An increasing number of Danes are living, and dying, with cardiovascular disease. There is good evidence for the impact of cardiac rehabilitation on coronary heart disease, heart failure and symptomatic peripheral arterial disease. However, more high-quality research is needed into a wider range of cardiac diseases including rehabilitation following cardiac arrest, and palliative care for patients with advanced heart disease. In this review it is discussed how to improve the quality of care and identify the direction of future research and development.

AB - Monoclonal antibodies inhibiting proprotein convertase subtilisin-kexin type 9 constitute a new class of lipid-lowering drugs. Currently, evolocumab and alirocumab are marketed. A recent cardiovascular outcome study with evolocumab has shown a cardiovascular (CV) event reduction of 15% in high-risk individuals at very low levels of low-density lipoproteins. The adverse event profile up to two years is mild. Treatment is very costly, and data on CV endpoints are still limited. Treatment is restricted to patients at very high risk of getting CV diseases and on a maximal tolerated statin and ezetimibe treatment in addition to dietary intervention. PMID- 30274589 TI - [Recurrence of venous thromboembolism]. AB - Recurrence of venous thromboembolism (VTE) is seen in approximately one third of the patients after discontinuation of therapy with anticoagulants. The duration of treatment seems to be of minor importance, as several studies have shown the same recurrence rate over years after treatment for three months and up to 24 months. In patients with reversible risk factors, three months of treatment seems to be sufficient. Treatment duration should be determined by physicians with special expertise in risk factors for VTE recurrence and bleeding complications. PMID- 30274590 TI - [Transcatheter aortic valve implantation in Denmark]. AB - During the latest decade, transcatheter aortic valve implantation (TAVI) has evolved from being indicated only in patients with severe aortic stenosis and prohibitive or high surgical risk, to be an alternative to surgical aortic valve replacement in patients with intermediate surgical risk. Improvements of the peri procedural management have resulted in marked reduction of complications and an increasing number of patients treated with TAVI every year in Denmark. By a minimalist approach, TAVI can be performed in local anesthaesia, with same day mobilisation and discharge within few days, without affecting the safety. PMID- 30274591 TI - [Patent foramen ovale closure in patients with apoplexia]. AB - Epidemiological studies have shown a larger prevalence of patent foramen ovale (PFO) in patients with cryptogenic ischaemic stroke (CIS) than in patients without CIS. In 2017, three randomised clinical trials showed a beneficial effect of PFO closure in patients with CIS. Among patients with CIS and PFO, those who underwent PFO closure, had a lower risk of stroke recurrence than those treated with antithrombotic therapy alone. In this review, we analyse the existing evidence and set up suggestions for future recommendations for PFO closure in patients with CIS. PMID- 30274592 TI - [Precision cardiology]. AB - Cardiology relies on a huge amount of data derived from clinical observations, case-specific considerations and randomised controlled trials. At best, medical intervention relieves symptoms and reduces disease consequences or complications. Rarely, it redirects the cause. However, an accelerated array of opportunities within a digital and molecular discourse may mark a medical era which acknowledges individual variation rather than accepts a pragmatic pooling of similarities. This review aims at providing a brief overview of academic achievements, clinical considerations and translational perspectives related to precision cardiology.

PMID- 30274593 TI - Tri-methylation of histone H3 lysine 4 facilitates gene expression in ageing cells. AB - Transcription of protein coding genes is accompanied by recruitment of COMPASS to promoter-proximal chromatin, which methylates histone H3 lysine 4 (H3K4) to form H3K4me1, H3K4me2 and H3K4me3. Here, we determine the importance of COMPASS in maintaining gene expression across lifespan in budding yeast. We find that COMPASS mutations reduce replicative lifespan and cause expression defects in almost 500 genes. Although H3K4 methylation is reported to act primarily in gene repression, particularly in yeast, repressive functions are progressively lost with age while hundreds of genes become dependent on H3K4me3 for full expression. Basal and inducible expression of these genes is also impaired in young cells lacking COMPASS components Swd1 or Spp1. Gene induction during ageing is associated with increasing promoter H3K4me3, but H3K4me3 also accumulates in non promoter regions and the ribosomal DNA. Our results provide clear evidence that H3K4me3 is required to maintain normal expression of many genes across organismal lifespan. PMID- 30274597 TI - Thy Mind, Thy Brain and Time. PMID- 30274598 TI - Millisecond Spike Timing Codes for Motor Control. AB - Millisecond variations in spiking patterns can radically alter motor behavior, suggesting that traditional rate-based theories of motor control require revision. The importance of spike timing in sensorimotor control arises from dynamic interactions between the nervous system, muscles, and the body. New mechanisms, model systems, and theories are revealing how these interactions shape behavior. PMID- 30274599 TI - Evolution of Locomotor Rhythms. AB - Nervous systems control locomotion using rhythmically active networks that orchestrate motor neuron firing patterns. Whether animals use common or distinct genetic programs to encode motor rhythmicity remains unclear. Cross-species comparisons have revealed remarkably conserved neural patterning systems but have also unveiled divergent circuit architectures that can generate similar locomotor behaviors. PMID- 30274600 TI - Language and the Construction of Time through Space.

PMID- 30274601 TI - Memory, Novelty and Prior Knowledge. AB - Over the 40 years that TINS has been in existence, there has been substantial progress in understanding the types, organisation, and neural mechanisms of memory. The selectivity of memory maintenance and retention remains a puzzle, and we here summarise two contributions of our own research to this enigma: the striking impact of the novelty and surprise often of other events happening around the time that a new memory is encoded and how activated prior knowledge guides the updating process that characterises aspects of memory consolidation. PMID- 30274602 TI - Hormonal Cycles, Brain Network Connectivity, and Windows of Vulnerability to Affective Disorder. AB - The rate of affective disorder is substantially higher in women than in men, and considerable evidence points to the actions of ovarian hormones in mediating this disparity. In this Opinion, we discuss the hypothesis that cyclic changes in ovarian hormone levels produce cyclic alterations in connectivity between the intrinsic networks of the brain. These alterations produce specific temporal windows within the menstrual cycle when internetwork connectivity is increased, associated with increased stress reactivity and better memory for unpleasant, arousing events, leading to increased negative mood and susceptibility to affective disorder. Our windows of vulnerability model offers insights for both treatment of affective disorder and research on sex differences in the brain. PMID- 30274603 TI - Circadian Clocks and Sleep: Impact of Rhythmic Metabolism and Waste Clearance on the Brain. AB - The rotation of the Earth around its axis causes periodic exposure of half of its surface to sunlight. This daily recurring event has been internalized in most organisms in the form of cellular circadian clock mechanisms. These cellular clocks are synchronized with each other in various ways to establish circadian networks that build the circadian program in tissues and organs, coordinating physiology and behavior in the entire organism. In the mammalian brain, the suprachiasmatic nucleus (SCN) receives light information via the retina and synchronizes its own neuronal clocks to the light signal. Subsequently, the SCN transmits this information to the network of clocks in tissues and organs, thereby synchronizing body physiology and behavior. Disruption of cellular clocks and/or destruction of the synchronization between the clocks, as experienced for instance in jet lag and shift-work conditions, affects normal brain function and can lead to metabolic problems, sleep disturbance, and accelerated neurological decline. In this review, we highlight ways through which the circadian system can coordinate normal brain function, with a focus on metabolism and metabolic astrocyte-neuron communications. Recent developments, for example, on how waste clearance in the brain could be modulated by the circadian clock, will also be discussed. This synthesis provides insights into the impact of metabolism not only on the circadian clock, but also on sleep and how this connection may exacerbate neurological diseases. PMID- 30274606 TI - When Sound Stops: Offset Responses in the Auditory System. AB - The auditory modality is fundamentally a temporal sense that requires analysis of changes in sound signals on timescales ranging from microseconds to minutes. To generate a faithful representation of changes in sound intensity and frequency over time, sound offsets (disappearances) as well as sound onsets (appearances) must be encoded by the auditory system. We review here the computational significance, perceptual roles, anatomical locations, and cellular and network origins of sound-offset responses in the mammalian auditory brain. We show that sound-offset responses arise from mechanisms and pathways distinct from those producing sound-onset responses, and are likely to be essential for auditory processing of temporally discontinuous sounds such as speech. PMID- 30274604 TI - Inhibitory Interneurons Regulate Temporal Precision and Correlations in Cortical Circuits. AB - GABAergic interneurons, which are highly diverse, have long been thought to contribute to the timing of neural activity as well as to the generation and shaping of brain rhythms. GABAergic activity is crucial not only for entrainment of oscillatory activity across a neural population, but also for precise regulation of the timing of action potentials and the suppression of slow timescale correlations. The diversity of inhibition provides the potential for flexible regulation of patterned activity, but also poses a challenge to identifying the elements of excitatory-inhibitory interactions underlying network engagement. This review highlights the key roles of inhibitory interneurons in spike correlations and brain rhythms, describes several scales on which GABAergic inhibition regulates timing in neural networks, and identifies potential consequences of inhibitory dysfunction. PMID- 30274608 TI - The Combinatorial Creature: Cortical Phenotypes within and across Lifetimes. AB - The neocortex is one of the most distinctive structures of the mammalian brain, yet also one of the most varied in terms of both size and organization. Multiple processes have contributed to this variability, including evolutionary mechanisms (i.e., alterations in gene sequence) that alter the size, organization, and connections of neocortex, and activity dependent mechanisms that can also modify these same features. Thus, changes to the neocortex can occur over different time scales, including within a single generation. This combination of genetic and activity dependent mechanisms that create a given cortical phenotype allows the mammalian neocortex to rapidly and flexibly adjust to different body and environmental contexts, and in humans permits culture to impact brain construction. PMID- 30274607 TI - Roles of Brain Criticality and Multiscale Oscillations in Temporal Predictions for Sensorimotor Processing. AB - Sensorimotor predictions are essential for adaptive behavior. In natural environments, events that demand sensorimotor predictions unfold across many timescales, and corresponding temporal predictions (either explicit or implicit) should therefore emerge in brain dynamics. Neuronal oscillations are scale specific processes found in several frequency bands. They underlie periodicity in sensorimotor processing and can represent temporal predictions via their phase dynamics. These processes build upon endogenous neural rhythmicity and adapt in response to exogenous timing demands. While much of the research on periodicity in neural processing has focused on subsecond oscillations, these fast-scale rhythms are in fact paralleled by critical-like, scale-free dynamics and fluctuations of brain activity at various timescales, ranging from seconds to hundreds of seconds. In this review, we put forth a framework positing that critical brain dynamics are essential for the role of neuronal oscillations in timing and that cross-frequency coupling flexibly organizes neuronal processing across multiple frequencies. PMID- 30274609 TI - When to Choose Surgery in the Era of Transcatheter Aortic Valve Replacement. AB - Treatment of severe symptomatic aortic stenosis has undergone significant changes with the advent of transcatheter aortic valve replacement (TAVR). Initially reserved for inoperable patients, these devices have improved; outcomes now rival or outperform surgical treatment. TAVR is recommended for high-risk and certain intermediate-risk patients. As transcatheter aortic valve replacement becomes an option for younger, healthier patients, long-term planning and thoughtful considerations of potential subsequent interventions are paramount. A robust understanding of risks, benefits and expected outcomes with TAVR is critical to provide patients with the best treatment option. PMID- 30274610 TI - Minimalist Transcatheter Aortic Valve Replacement: The Right Pathway Forward? AB - Minimalist transcatheter aortic valve replacement (TAVR) can be implemented with no apparent compromise in patient outcomes. Although this approach is applicable for many patients undergoing TAVR, patient selection by the heart team is critical; one must be cognizant of factors whereby a minimalist approach is unsuitable. In the current era of TAVR, a minimalist approach should encompass the entire process of care and not just the procedure. Streamlining and homogenizing preprocedural workup has potential benefits for patients and health services. Minimalist TAVR is likely the right pathway forward for most patients, but the focus should be patient centered with no compromise to safety. PMID- 30274605 TI - Short-Term Synaptic Plasticity as a Mechanism for Sensory Timing. AB - The ability to detect time intervals and temporal patterns is critical to some of the most fundamental computations the brain performs, including the ability to communicate and appraise a dynamically changing environment. Many of these computations take place on the scale of tens to hundreds of milliseconds. Electrophysiological evidence shows that some neurons respond selectively to duration, interval, rate, or order. Because the time constants of many time varying neural and synaptic properties, including short-term synaptic plasticity (STP), are also in the range of tens to hundreds of milliseconds, they are strong candidates to underlie the formation of temporally selective neurons. Neurophysiological studies indicate that STP is indeed one of the mechanisms that contributes to temporal selectivity, and computational models demonstrate that neurons embedded in local microcircuits exhibit temporal selectivity if their synapses undergo STP. Converging evidence suggests that some forms of temporal selectivity emerge from the dynamic changes in the balance of excitation and inhibition imposed by STP. PMID- 30274611 TI - Paravalvular Regurgitation After Transcatheter Aortic Valve Replacement: Is the Problem Solved? AB - Paravalvular regurgitation is a frequent complication after transcatheter aortic valve replacement and its association with worse outcomes depends on the degree of its severity. Despite substantial improvement in transcatheter heart valve design, sizing and implantation technique, moderate or severe paravalvular regurgitation still occurs in 2% to 7% of patients and is associated with a more than 2-fold increase in mortality. This review provides a state-of-the-art approach to (i) paravalvular regurgitation prevention by optimizing patient selection, valve sizing, and positioning and (ii) the detection, quantitation and management of paravalvular regurgitation during and after valve implantation. PMID- 30274612 TI - Revisiting Atrial Fibrillation in the Transcatheter Aortic Valve Replacement Era. AB - Atrial fibrillation (AF) is a known complication of many cardiac procedures, including those undergoing surgical aortic valve replacement (SAVR). In the transcatheter aortic valve replacement (TAVR) era, AF has been noted not only to be present in these patients but also associated with morbidity and mortality. In this article, we first outline the significance of AF in general and then more specifically in patients undergoing cardiac surgery. We then compare and contrast specific clinical issues related to AF in patients with aortic stenosis undergoing aortic valve replacement, traditionally with SAVR, but now increasingly more common with TAVR. PMID- 30274614 TI - Transcatheter Aortic Valve Replacement for Bicuspid Aortic Valve: Challenges and Pitfalls. AB - Because of the unfavorable anatomic features of bicuspid aortic stenosis (AS), the outcomes of transcatheter aortic valve replacement (TAVR) in bicuspid AS were suboptimal, particularly when using the first-generation transcatheter valves. However, the newer-generation transcatheter valves significantly improved the outcomes of TAVR in bicuspid AS. Nonetheless, long-term durability of transcatheter valves and concomitant aortopathy should be taken into account. Considering the expanding indication of TAVR to lower the surgical risk and a younger population, these issues should be evaluated in future studies. PMID- 30274613 TI - Coronary Artery Disease and Transcatheter Aortic Valve Replacement: When to Intervene. AB - "In patients with coronary artery disease undergoing transcatheter aortic valve replacement (TAVR), the decision of whether to revascularize, which lesions to revascularize, and the optimal timing of revascularization remains controversial. The sequence of revascularization should be made on a case-by-case basis. Pre TAVR revascularization (staged or simultaneous with TAVR) is preferred due to unobstructed access to coronary ostia and is important to consider especially in cases in which long self-expanding valves are used. In patients who are hemodynamically compromised, the valve should be addressed first, as the most important cause of mortality is heart/multiorgan failure." PMID- 30274616 TI - Endovascular Treatment Options for the Aortic Arch. AB - Endovascular aortic repair to treat aortic arch abnormality has rapidly expanded in the last 2 decades, and surgeons now have options to treat patients who are poor candidates for open surgery. The devices and techniques should be tailored to the extension of the aortic abnormality and anatomy of the individual. Recent studies demonstrate promising results with branched endografts, but one of the major drawbacks of the devices is that considerable time is required to prepare the custom-made graft, which may not be available for emergent or urgent cases. Introduction of commercially available devices is forthcoming. PMID- 30274615 TI - Innovations in Transcatheter Valve Technology: What the Next Five Years Hold. AB - Transcatheter aortic valve replacement is indicated for the treatment of symptomatic severe aortic stenosis in patients at intermediate or greater risk for surgery. Future indications may include low-risk patients, asymptomatic patients, bicuspid valves, moderate aortic stenosis, and pure native aortic valve regurgitation. Key hurdles to overcome include pacemaker risk, vascular injury, paravalvular regurgitation, coronary artery reaccess, durability, and embolic risk. New valve designs include synthetic polymeric valves that may allow for greater durability, in addition to advances in terms of precise positioning and repositioning to reduce the complication rate.

PMID- 30274618 TI - Type 2 diabetes and coronary artery disease: Preserved ejection fraction and sudden cardiac death. AB - BACKGROUND: Previous studies have shown that type 2 diabetes (DM2) is associated with sudden cardiac death (SCD) risk in post-myocardial infarction patients. The treatment of coronary artery disease (CAD) as well as DM2 has changed over time. OBJECTIVE: The purpose of this study was to compare the incidence of SCD in DM2 and nondiabetic patients with CAD and preserved ejection fraction (EF) in a prospective observational study (ARTEMIS study). METHODS: In 834 DM2 patients and 1112 nondiabetic patients with CAD enrolled, the EF measured >=3 months after qualifying was 63% +/- 10% in DM2 patients and 65% +/- 8% in nondiabetic patients (P < .01). The primary end point was SCD or resuscitation from sudden cardiac arrest (SCA). All-cause mortality, cardiac mortality, non-SCD, hospitalization for heart failure, and acute coronary syndrome were secondary end points. RESULTS: During a mean follow-up of 6.3 +/- 1.6 years, SCDs/SCAs occurred in 50 patients. The prevalence of SCD/SCA was higher in DM2 patients (4.1%) than in nondiabetic patients (1.4%) (adjusted hazard ratio 2.6; 95% confidence interval 1.3-5.3; P < .01). However, the non-SCD component of cardiac mortality was not significantly different between DM2 and nondiabetic patients. In addition, heart failure hospitalizations were more common in DM2 patients (8.4%) than in nondiabetic patients (2.9%) (P < .001). The annual cardiac mortality in nondiabetic patients with CAD was 0.50%, which was lower than the 0.59% reported in the general Finnish population. CONCLUSION: DM2 is an independent risk factor for SCD/SCA in CAD patients with preserved EF. Cardiac mortality in nondiabetic CAD patients is slightly lower than that in the general population in the present treatment era. PMID- 30274619 TI - A wobbling tachycardia: What is the mechanism?

AB - Antineutrophil cytoplasmic antibody-associated vasculitis (AAV) is the most common cause of rapidly progressive glomerulonephritis. ANCAs play an important role in the pathogenesis and diagnosis of AAV. The classic renal lesion in AAV is a pauci-immune necrotizing and crescentic glomerulonephritis. Treatment is divided into 2 phases: (1) induction of remission to eliminate disease activity and (2) maintenance of remission to prevent disease relapse. AAV patients with end-stage renal disease require modification of immunosuppressive strategies and consideration for kidney transplantation. An improved understanding of disease pathogenesis has led to new treatment strategies being tested in clinical trials. PMID- 30274622 TI - Therapy for Proliferative Lupus Nephritis. AB - Proliferative lupus nephritis requires prompt diagnosis and treatment with immunosuppressive therapy. Cyclophosphamide is the longest studied agent, but mycophenolate mofetil has recently emerged as an efficacious induction and maintenance treatment that does not impart the risk of infertility. However, overall remission rates remain suboptimal and there is a need for improved therapeutic options. To this end, ongoing clinical studies are focusing on agents that target key molecules and pathways implicated in the pathogenesis of lupus nephritis based on previous animal and human studies. This article reviews key findings of trials supporting established induction and maintenance treatment regimens along with novel therapeutic investigations. PMID- 30274623 TI - Nonproliferative Forms of Lupus Nephritis: An Overview. AB - Most of the attention paid to lupus nephritis, in the medical literature and in clinical trials, has primarily focused on proliferative forms of lupus nephritis (class III and IV lesions), but with lower thresholds to biopsy and rebiopsy patients with lupus, clinicians are encountering more cases with purely mesangial disease (class I and II) or membranous nephropathy patterns (class V). These lesions often will be associated with milder disease courses but still require dedicated follow-up by a nephrologist and focused therapeutic strategies that, at times, will include immunosuppression. PMID- 30274625 TI - Secondary, AA, Amyloidosis. AB - Secondary, AA, amyloidosis is a rare systemic complication that can develop in any long-term inflammatory disorder, and is characterized by the extracellular deposition of fibrils derived from serum amyloid A (SAA) protein. SAA is an acute phase reactant synthetized largely by hepatocytes under the transcriptional regulation of proinflammatory cytokines. The kidney is the major involved organ with proteinuria as first clinical manifestation; renal biopsy is the commonest diagnostic investigation. Targeted anti-inflammatory treatment promotes normalization of circulating SAA levels preventing amyloid deposition and renal damage. Novel therapies aimed at promoting clearance of existing amyloid deposits soon may be an effective treatment approach. PMID- 30274624 TI - Renal Manifestations of Rheumatoid Arthritis. AB - Renal manifestations in rheumatoid arthritis (RA) have evolved as RA management has improved. In the past, older disease-modifying antirheumatic drugs, uncontrolled systemic inflammation, and chronic nonsteroidal antiinflammatory drug (NSAID) use contributed to kidney disease. Over time, the use of methotrexate and biologic medications, decrease in NSAID use, and a treat-to target strategy have contributed to a decrease in renal manifestations. Chronic kidney disease in RA now is more likely to be caused by cardiovascular risk factors than uncontrolled RA disease severity. In patients with renal dysfunction, NSAIDs, methotrexate, and tofacitinib may need to be adjusted or avoided to prevent adverse events. PMID- 30274626 TI - Nephrotoxicity of Select Rheumatologic Drugs. AB - Several drugs commonly used in the management of rheumatic diseases may lead to nephrotoxicity, electrolyte disturbances, and hypertension.

The authors include a drug dosing table for patients with kidney disease. PMID- 30274627 TI - Acute and Chronic Tubulointerstitial Nephritis of Rheumatic Causes. AB - Tubulointerstitial nephritis (TIN) is the second most common cause of acute intrinsic kidney injury after acute tubular necrosis. Although drug-induced forms of TIN represent the vast majority, rheumatic disease is another common cause and often underdiagnosed. Early diagnosis of acute interstitial nephritis and prompt withdrawal of the culprit medication or a correct treatment can avoid chronic damage and progressive chronic kidney disease. This review highlights the recent updates, clinical features, and treatment in TIN in autoimmune rheumatic disease. PMID- 30274628 TI - Thrombotic Microangiopathies with Rheumatologic Involvement. AB - Thrombotic microangiopathies are heterogeneous disorders characterized by microangiopathic hemolytic anemia with thrombocytopenia and renal injury. There are a variety of causes, including metabolic disorders, infections, medications, complement disorders, pregnancy, malignancy, and autoimmune disorders. This review focuses on renal thrombotic microangiopathy in the setting of rheumatologic diseases. Systemic lupus erythematosus is the most common autoimmune disease associated with thrombotic microangiopathy. Other etiologies include scleroderma renal crisis and antiphospholipid antibody syndrome, which can be primary or secondary to autoimmune diseases including systemic lupus erythematosus. There have also been case reports of thrombotic microangiopathy in the setting of rheumatoid arthritis and dermatomyositis. PMID- 30274629 TI - Anti-Glomerular Basement Membrane Disease. AB - Anti-glomerular basement membrane (anti-GBM) disease is a rare autoimmune small vessel vasculitis characterized by autoreactivity to antigens in type IV collagen chains expressed in glomerular and alveolar basement membrane. The detection of circulating anti-GBM antibodies, which are shown to be directly pathogenic, is central to disease diagnosis. Clinically, anti-GBM disease usually presents with rapidly progressive glomerulonephritis with or without alveolar hemorrhage. Rapid diagnosis and early treatment are required to prevent mortality and to preserve renal function. Relapse in anti-GBM disease is uncommon. Variant and atypical forms of anti-GBM disease are increasingly recognised. PMID- 30274630 TI - Autoimmune Kidney Diseases Associated with Chronic Viral Infections. AB - Autoimmune kidney diseases triggered by viruses are an important cause of kidney disease in patients affected by chronic viral infection. Hepatitis B virus (HBV) infection is associated with membranous nephropathy and polyarteritis nodosa. Hepatitis C virus (HCV) infection is a major cause of cryoglobulinemic glomerulonephritis. Patients with human immunodeficiency virus (HIV) may develop HIV-associated nephropathy, a form of collapsing focal segmental glomerulosclerosis, or various forms of immune-complex-mediated kidney diseases. This article summarizes what is known about the pathogenesis, diagnosis, and management of immune-mediated kidney diseases in adults with chronic HBV, HCV, and HIV infections. PMID- 30274632 TI - Renal Involvement in Rheumatic Diseases. PMID- 30274631 TI - Renal Manifestations of Inflammatory Bowel Disease. AB - Renal and urinary involvement has been reported to occur in 4% to 23% of inflammatory bowel disease (IBD) patients. Parenchymal renal disease is rare and most commonly affects glomerular and tubulointerstitial compartments. The most common findings on renal biopsy of IBD patients are IgA nephropathy and tubulointerstitial nephritis. Overall morbidity of IBD-related renal manifestations is significant, and there is often only a short window of injury reversibility. This, along with subtle clinical presentation, requires a high index of suspicion and routine monitoring of renal function. There are no established guidelines for the optimal screening and monitoring of renal function in IBD patients.

PMID- 30274634 TI - Reconfiguring Cardiac Rehabilitation to Achieve Panvascular Prevention: New Care Models for a New World. AB - Atherosclerotic cardiovascular disease (ASCVD) and its associated economic burden are increasing globally. Although cardiac rehabilitation is a vital component of secondary prevention with proven benefits, it is underutilized due to numerous barriers, especially in resource-limited settings. New care models for delivery of comprehensive prevention programs such as community-based, home-based, and "hybrid" models implementing m-health, e-health, and telemedicine need to be adopted. Such new care models should be offered to all patients with established ASCVD (coronary, cerebral, and peripheral) and additionally to those at high risk of developing ASCVD with multiple risk factors for panvascular prevention. PMID- 30274635 TI - Smoking Cessation and Cardiac Rehabilitation: A Priority! AB - Cardiac rehabilitation programmes afford the opportunity to enhance cardiovascular health and reduce the risk of subsequent cardiac events. They permit the management of cardiac risk factors while addressing significant psychosocial and vocational issues. Tobacco addiction is the most important of the modifiable cardiac risk factors, and smoking cessation is the most important secondary prevention strategy. Cessation is more likely when cessation pharmacotherapy is accompanied by supportive advice and strategic assistance. A systematic approach to the delivery of cessation services, such as the Ottawa Model of Smoking Cessation, greatly enhances the likelihood of success. Cardiac rehabilitation programmes are ideal venues for the delivery of such programmes. PMID- 30274636 TI - Cardiac Rehabilitation Availability and Delivery in Canada: How Does It Compare With Other High-Income Countries? AB - BACKGROUND: Canada has insufficient cardiac rehabilitation (CR) capacity, yet unmet need is unknown. Moreover, Canada has CR guidelines, but whether delivery conforms has not been characterized by province/territory. This study aimed to establish (1) CR volumes, capacity, and density, as well as (2) the nature of programs, and (3) compare these (a) by province/territory and (b) with other high income countries (HICs). METHODS: In this cross-sectional study, an online survey was administered to CR programs globally. National cardiac associations were engaged to facilitate program identification where available, or local champions. Density was computed using Canada's Chronic Disease Surveillance System ischemic heart disease incidence estimates. Twenty-eight HICs with CR were selected for comparison (N = 619 programs), and multilevel analyses performed. RESULTS: CR was available in 10 of 13 (76.9%) provinces (no programs in Canada's North), with 74 of 182 programs initiating a survey (40.7% response). Program volumes (median = 250) were greatest in Ontario, but ultimately there was only 1 CR spot per 4.55 patients with ischemic heart disease nationally (similar in other HICs), and 186,187 more spots are needed annually. Most programs were funded by government/hospital sources (n = 48, 66.7%), but in 23 (31.5%), patients paid some or all of program costs out-of-pocket. Guideline-indicated conditions were accepted in more than 90% of programs. Programs had a multidisciplinary team of 6.2 +/- 2.1 staff, offering 7.7 +/- 1.5/10 core components (varied by province, P = 0.001; return-to-work offered less frequently than other HICs; P = 0.03), over 42.0 +/- 26.0 hours (provincial and other HIC differences, P < 0.001). CONCLUSIONS: Canadian CR capacity must be augmented, but where available, services are consistent with other HICs. PMID- 30274637 TI - Cardiac Rehabilitation for Adults With Congenital Heart Disease: Physical and Psychosocial Considerations. AB - Owing to significant medical advances, it is now estimated that more than 90% of persons born with congenital heart disease (CHD) will reach adulthood. Medically appropriate physical activity represents an opportunity to improve physical functioning as well as quality of life and psychosocial outcomes. By reviewing published CHD research and clinical recommendations, herein we first summarize how adults with CHD are known to be less physically active and have reduced exercise capacity compared with healthy peers. Cardiopulmonary exercise testing is important for routine clinical management and before the onset of an exercise program. Physiological anomalies are common in adults with CHD, although very few necessitate activity restrictions, and positive results from exercise training have been demonstrated. In recent decades, the focus has thus shifted from restriction of exercise to promotion of exercise. Adults with CHD also face unique psychosocial challenges associated with living with a chronic cardiac condition, many of which may influence exercise behaviours. However, much less is known about participation of adults with CHD in cardiac rehabilitation (CR) programs, which differ from exercise training in their comprehensive, interdisciplinary approach to management of chronic disease and that might be uniquely poised to meet the physical and psychosocial needs of adults with CHD. Initial CR outcomes have been positive and with no reported adverse events. This review summarizes the unique physical and psychosocial considerations that may guide the provision of CR to adults with CHD. PMID- 30274638 TI - The Delivery of Cardiac Rehabilitation Using Communications Technologies: The "Virtual" Cardiac Rehabilitation Program. AB - Cardiac rehabilitation (CR) programs are a proven therapy for patients with cardiovascular disease, reducing future cardiac events and premature mortality. However, as little as 10% of eligible patients attend these programs, with a key reason being geographical inaccessibility. In Canada, more than 90% of Canadians have Internet access, and there are approximately 31 million cell phone subscribers, with these numbers expected to continue to increase. The proliferation of these affordable communications technologies has opened up opportunities for patient communication while bridging geographic distance. This has led to the development of "virtual" CR that can be remotely conducted, reaching patients in their homes and communities. These programs have used a range of technologies such as telephone, Internet, text messaging, and smartphones. Early research has focused on acceptance of use and feasibility in pilot studies, indicating patient willingness for use. More recently, a number of small, randomized trials have been conducted indicating potential positive effect on various clinical outcomes. This narrative review highlights the evidence to date on the use of virtual CR, using a variety of affordable communications technologies from early feasibility studies to modest randomized controlled trials. Finally, lessons from previous studies are discussed to help inform the development and testing of future virtual CR. This will be important if virtual CR is to become part of standard health care. PMID- 30274639 TI - The Effects of Cardiac Rehabilitation in Patients With Atrial Fibrillation: A Systematic Review. AB - BACKGROUND: Atrial fibrillation (AF), the most common sustained cardiac arrhythmia, is associated with substantial morbidity and mortality. Clinical guidelines for managing patients with AF do not include a referral to cardiac rehabilitation (CR) at present, although it is routine for most other cardiovascular conditions. The number of studies evaluating the impact of CR on the health of patients with AF is growing, but there has been no consolidation of the findings. The objective of this systematic review was to evaluate the impact of CR programs on physical and mental health outcomes in patients with all forms of AF. METHODS: Six electronic databases were searched to identify all studies that reported on the impact of CR in patients with AF. Searching identified 5771 potential articles, of which 12 were included. The physical health outcomes evaluated included cardiometabolic health indicators, aerobic and functional capacity, severity of symptoms, recurrence of AF, hospitalizations, and mortality. The mental health outcomes assessed included quality of life, anxiety, depression, and quality of sleep. RESULTS: The limited evidence supports the use of CR to improve cardiometabolic health indicators and aerobic and functional capacity in patients with AF. The current evidence suggests that prominent improvements in aerobic fitness are associated with lower risk of hospitalization and mortality. The conflicting mental health findings may be due to the varying severity of AF and or modes of exercise interventions. CONCLUSIONS: Gaps in the research identified the need for greater rigor in the reporting of intervention details, outcomes, and statistical methodology; sex- and gender-based analyses; and effectiveness trials. This review serves as a call to action for more work globally on this important area. PMID- 30274640 TI - Investigating the effect of treatment at high-volume hospitals on overall survival following cytoreductive nephrectomy. AB - PURPOSE: Data revealed the benefit of high-volume care in many complex disease processes. Among patients undergoing nephrectomy, those receiving cytoreductive nephrectomy (CN) for metastatic renal cell cancer (mRCC) constitute a unique subset. They often have a greater medical and surgical complexity. Against this backdrop, we sought to investigate the effect of hospital volume on overall survival among patients undergoing CN for mRCC. MATERIAL AND METHODS: We identified 11,089 patients who received CN for mRCC in the National Cancer Database from 1998 to 2012. We ranked hospitals based on annual CN volume. Patients who received surgery in hospitals in the top vs. bottom deciles were compared. Inverse Probability of Treatment Weighting (IPTW)-adjusted Kaplan-Meier and Cox regression analyses were used to compare the primary endpoint of overall survival between balanced cohorts of patients. Secondary endpoints were 30-day mortality, 30-day readmissions, and receipt of subsequent systemic therapy. RESULTS: Median follow-up was 60.39 months (interquartile range [IQR] 35.09 95.95). Median overall survival was 17.61 months (IQR 7.16-44.58). Following propensity score weighting, surgery at a high-volume hospital was associated with a decreased risk of mortality (IPTW-adjusted Cox proportional Hazard Ratio = 0.91; 95% confidence interval: 0.86-0.96). On our IPTW-adjusted Kaplan-Meier analysis, the median survival was 19.94 months (IQR 7.98-50.27) at high-volume hospitals vs. 15.97 months (IQR 6.6-41.56) at low-volume hospitals. With regard to secondary endpoints, the data did not reveal a significant advantage for treatment at a high-volume hospital. CONCLUSION: We found a significant association between receipt of CN at high-volume hospitals and prolonged overall survival, demonstrated by a nearly 4 month survival benefit. PMID- 30274641 TI - Prognostic factors of oncologic outcomes in metastatic chemotherapy-naive castration-resistant prostate cancer treated with enzalutamide in actual clinical practice in East Asia. AB - OBJECTIVES: We aimed to evaluate the prognostic factors for chemotherapy-naive castration-resistant prostate cancer (CRPC) treated with enzalutamide in actual clinical practice using easily accessible clinical variables. METHODS AND MATERIALS: We retrospectively reviewed the following data from 113 patients with chemotherapy-naive CRPC treated with enzalutamide: serum levels of prostate specific antigen (PSA), testosterone, hemoglobin, total protein, albumin, and alkaline phosphatase (ALP); platelet, neutrophil, and lymphocyte counts; neutrophil-to-lymphocyte ratios (NLRs); and liver profiles. PSA progression-free survival (PFS), radiological PFS, and overall survival were estimated by Cox regression analysis. RESULTS: Compared with baseline levels, laboratory values at 2 months showed significantly lower PSA (160.2 +/- 351.5 ng/ml vs. 47.4 +/- 117.1 ng/ml) and ALP levels (201.86 +/- 223.77 IU/l vs. 148.25 +/- 146.81 IU/l) and a significantly higher percentage of lymphocytes (28.1% +/- 10.6% vs. 31.2% +/- 9.7%); those at 1 month showed a significantly lower percentage of neutrophils (61.0% +/- 11.0% vs. 57.1% +/- 12.5%). In the multivariate analysis, poor prognostic factors for PSA PFS were Gleason score >= 9 (hazard ratio [HR] 2.022; P = 0.0250); visceral metastasis (HR 3.143; P = 0.0002); high NLR (HR 1.205; P = 0.0126); and high ALP (HR 1.002; P = 0.0015). For radiological PFS, high NLR (HR 1.249; P = 0.0002) and high ALP (HR 1.002; P = 0.0001) were associated with poor outcomes. The predictors of poor overall survival were visceral metastasis (HR 3.155; P < 0.0001); high NLR (HR 1.341; P < 0.0001); and high ALP (HR 1.001; P = 0.0017). CONCLUSION: Enzalutamide is less effective in patients with metastatic chemotherapy-naive CRPC with Gleason scores >= 9, visceral metastasis, high NLR, and high ALP. PMID- 30274642 TI - Think, Ask, Act: The Intersectionality of Mental and Reproductive Health for Judicially Involved Girls. AB - Danielle Smith, a 16-year-old African-American girl newly detained at juvenile hall, presents for psychiatric evaluation. She describes a history of sexual abuse by her foster father and 2 years of commercial sexual exploitation after running away at 14 years of age. Scarcely more than 100 pounds, she endorses drug use, primarily marijuana, and notes prior use of cocaine and methamphetamine, provided by her trafficker (described as her "boyfriend"). She has a timid smile and uses music and journaling as her refuge. Danielle is unclear about past psychiatric diagnoses but does recall receiving medication from a psychiatrist while in foster care and expresses interest in resuming treatment. Girls in the juvenile justice system are a vulnerable population with overlapping substance use, reproductive, and mental health care needs. The conceptual framework of "intersectionality" is useful to better understand the multiplicity of biopsychosocial needs of girls involved in the justice system. Intersectionality is defined as "a theoretical framework for understanding how multiple social identities (ie, race, gender, and sexual orientation) intersect at the micro level of individual experience to reflect systems of oppression (ie, racism, sexism, classism) at the macro level."1 In this article, we propose the pragmatic application of the concept of intersectionality to better conceptualize the high unmet health needs of these youth. We conclude by providing recommendations for meeting their needs using the proposed "think, ask, act" approach. PMID- 30274643 TI - What's in a Name? Moving to Neuroscience-Based Nomenclature in Pediatric Psychopharmacology. AB - Our traditional names for psychotropic medication classes lead to unnecessary confusion. As clinicians, we have grown comfortable with idiosyncratic names of psychotropic medications and have forgotten how unclear and misleading they can be. For example, evidence shows that serotonin reuptake inhibitors help in pediatric anxiety disorders, but a parent with an anxious child might ask, "If you diagnosed my son with separation anxiety, why are you giving him an antidepressant?" Another parent might object to the use of a "stimulant" medication, "My daughter never slows down, the last thing she needs is a stimulant!" Similarly, an "antipsychotic" can be prescribed on-label to youth with mania, bipolar depression, tics, or irritability in autism but families and patients might be confused by or object to the implied label of being "psychotic." Furthermore, patients or family members may not feel comfortable asking clarifying questions and simply do not return for follow up-concluding that the provider does not understand their child.

AB - Child Psychiatry has long been recognized as the medical specialty with the greatest workforce shortage.1 This shortage is of increasing concern because of the high burden of child and adolescent mental illness that is exemplified by the increasing rates of suicide in youth. PMID- 30274645 TI - A Risk Calculator for Bipolar Disorder in Youth: Improving the Odds for Personalized Prevention and Early Intervention? AB - There have been many longitudinal studies examining biological and environmental risk factors for developing bipolar disorder in youth. Specifically, well established risk factors for bipolar disorder in children and adolescents include having a family history of bipolar disorder, depression, disruptive behavior disorders, psychosis, antidepressant-induced manic symptoms, anxiety, and subsyndromal symptoms of mania and depression.1 In an effort to identify individuals at highest risk for developing bipolar disorder, several investigators have attempted to characterize a bipolar prodrome. A recent meta analysis of early manifestations of bipolar disorder in youth found that the most common prodromal symptoms were increased energy, diminished ability to think, indecision, pressured speech, talkativeness, elated mood, academic or work difficulties, insomnia, depressed mood, and increased goal-directed activities.2 The authors concluded that despite many of the participants having symptoms prior to their illness onset, there was significant heterogeneity in symptom presentation, making it difficult to define a consistent bipolar prodrome. Although it is important to explore risk factors and rates of early symptoms of incipient bipolar disorder, to date, most studies have examined risk within an entire group rather than quantified an individual's risk of having bipolar disorder, which is essential to advance personalized monitoring and treatment strategies. PMID- 30274646 TI - Brain Markers of Familial Risk for Depression: Steps Toward Clinical Relevance? AB - An important goal in the field of psychiatry is to identify individuals at risk for major psychopathology, prior to actual onset of disorder. Discovery of risk markers that predict onset of disorder, if they are sensitive and specific, could help in the process of early diagnosis, and ultimately lead to improved early intervention and prevention. This is especially a key aspiration for disorders that take a tremendous toll on health and functioning in both adolescence and adulthood, including depression, bipolar disorder, and schizophrenia. PMID- 30274647 TI - Youth Suicide: The First Suicide Attempt. AB - A mainstay in the identification and management of youth at risk for suicide is the use of suicide risk factors, such as past suicide attempt(s), past or current suicidal ideation, mood disorders, substance use disorders, psychosis, male gender, and lack of family support.1 A history of at least 1 medically serious suicide attempt2 or violent self-harm3 is a particularly important risk factor. This phenomenon has been studied mostly with clinical samples, such as cohorts of patients initially admitted to a hospital for an attempt, having used a particular self-harm method, or seen in an emergency department.4 Olfson et al.3 used Medicaid claims data and tracked patients for 1 year after an episode of self-harm. However, these studies could not contextualize completed suicides that were not preceded by an attempt or other self-harm. McKean et al.,5 in this issue of JAACAP, used a community sample to identify a cohort followed from the first suicide attempt that came to medical attention to the index attempt (IA), including an IA resulting in death. This approach facilitated an analysis that included individuals who lived after or died from the IA, receipt of care, subsequent suicide completion, method of IA and completed suicides, and individuals' demographic and clinical characteristics. PMID- 30274648 TI - Prevalence and Characteristics of Self-Harm in Adolescents: Meta-Analyses of Community-Based Studies 1990-2015. AB - OBJECTIVE: To provide meta-analytic estimates of self-harm from all community based studies of adolescents from 1990 through 2015, estimates of suicidal risk, and characteristics including age profile, frequency, types, seeking help, and reasons. METHOD: Databases, bibliographies, and the internet were searched for cross-sectional and cohort studies of 12- to 18-year-olds. Meta-analytic estimates of the prevalence and characteristics of self-harm, risk of suicidal behaviors, and rates comparing different methods were calculated. RESULTS: One hundred seventy-two datasets reporting self-harm in 597,548 participants from 41 countries were included. Overall lifetime prevalence was 16.9% (95% CI 15.1 18.9), with rates increasing to 2015. Girls were more likely to self-harm (risk ratio 1.72, 95% CI 1.57-1.88). The mean age of starting self-harm was 13 years, with 47% reporting only 1 or 2 episodes and cutting being the most common type (45%). The most frequent reason was relief from thoughts or feelings. Slightly more than half sought help, but for most this was from a friend. Suicidal ideation (risk ratio 4.97) and attempts (risk ratio 9.14) were significantly higher in adolescents who self-harmed, but this was higher with more frequent self-harm. Methodologic factors also were associated with higher rates of self harm. CONCLUSION: Interventions that can lower suicidal risk should be made available to adolescents who self-harm frequently as soon as possible. Preventative interventions that help adolescents deal with negative feelings should be instituted at the onset of puberty. Because friends are frequently asked for support, interventions also should be developed for peer groups. PMID- 30274649 TI - Modifying the Impact of Eveningness Chronotype ("Night-Owls") in Youth: A Randomized Controlled Trial. AB - OBJECTIVE: To determine whether an intervention to reduce eveningness chronotype improves sleep, circadian, and health (emotional, cognitive, behavioral, social, physical) outcomes. METHOD: Youth aged 10 to 18 years with an evening chronotype and who were "at risk" in 1 of 5 health domains were randomized to: (a) Transdiagnostic Sleep and Circadian Intervention for Youth (TranS-C; n = 89) or (b) Psychoeducation (PE; n = 87) at a university-based clinic. Treatments were 6 individual, weekly 50-minute sessions during the school year. TranS-C addresses sleep and circadian problems experienced by youth by integrating evidence-based treatments derived from basic research. PE provides education on the interrelationship between sleep, stress, diet, and health. RESULTS: Relative to PE, TranS-C was not associated with greater pre-post change for total sleep time (TST) or bed time (BT) on weeknights but was associated with greater reduction in evening circadian preference (pre-post increase of 3.89 points, 95% CI = 2.94 4.85, for TranS-C, and 2.01 points, 95% CI = 1.05-2.97 for PE, p = 0.006), earlier endogenous circadian phase, less weeknight-weekend discrepancy in TST and wakeup time, less daytime sleepiness, and better self-reported sleep via youth and parent report. In terms of functioning in the five health domains, relative to PE, TranS-C was not associated with greater pre-post change on the primary outcome. However, there were significant interactions favoring TranS-C on the Parent-Reported Composite Risk Scores for cognitive health. CONCLUSION: For at risk youth, the evidence supports the use of TranS-C over PE for improving sleep and circadian functioning, and improving health on selected outcomes.

PMID- 30274650 TI - A Risk Calculator to Predict the Individual Risk of Conversion From Subthreshold Bipolar Symptoms to Bipolar Disorder I or II in Youth. AB - OBJECTIVE: Youth with subthreshold mania are at increased risk of conversion to bipolar disorder (BP) I/II. Predictors for conversion have been published for the group as a whole. However, risk factors are heterogeneous, indicating the need for personalized risk assessment. METHOD: One hundred forty youth with BP not otherwise specified (BP-NOS; 6-17 years old) followed through the Course and Outcome of Bipolar Youth (COBY) study with at least 1 follow-up assessment before conversion to BP-I/II were included. Youths were assessed on average every 7 months (median 11.5 years) using standard instruments. Risk predictors reported in the literature were used to build a 5-year risk calculator. Discrimination was measured using the time-dependent area under the curve after 1,000 bootstrap resamples. Calibration was evaluated by comparing observed with predicted probability of conversion. External validation was performed using an independent sample of 58 youths with BP-NOS recruited from the Pittsburgh Bipolar Offspring Study. RESULTS: Seventy-five (53.6%) COBY youths with BP-NOS converted to BP I/II, of which 57 (76.0%) converted within 5 years. Earlier-onset BP-NOS, familial hypomania/mania, and high mania, anxiety, and mood lability symptoms were important predictors of conversion. The calculator showed excellent consistency between the predicted and observed risks of conversion, good discrimination between converters and non-converters (area under the curve 0.71, CI 0.67-0.74), and a proportionally increasing rate of converters at each successive risk class. Discrimination in the external validation sample was good (area under the curve 0.75). CONCLUSION: If replicated, the risk calculator would provide a useful tool to predict personalized risk of conversion from subsyndromal mania to BP-I/II and inform individualized interventions and research. PMID- 30274652 TI - Limbic Intrinsic Connectivity in Depressed and High-Risk Youth. AB - OBJECTIVE: Depression runs in families and has been associated with dysfunctional limbic connectivity. Whether aberrant limbic connectivity is a risk factor for or a consequence of depression is unclear. To examine this question, we compared resting state functional connectivity (RSFC) in youth with depressive disorders (DEP), healthy offspring of parents with depression (DEP-risk), and healthy comparison (HC) youth. METHOD: Magnetic resonance imaging at rest was acquired from 119 youth, aged 8 to 17 years (DEP, n = 41, DEP-risk, n = 39, and HC, n = 39) and analyzed using seed-based RSFC in bilateral amygdala and nucleus accumbens (NAcc), covarying for age, IQ, and sex. RESULTS: We found distinct risk and disorder-specific patterns of RSFC across groups. DEP-risk and DEP youth shared reduced negative amygdala-right frontal cortex RSFC and reduced positive amygdala-lingual gyrus RSFC compared to HC youth (p < .001). DEP-risk youth had weaker negative amygdala-precuneus RSFC compared to DEP and HC youth (p < .001), suggesting a resilience marker for depression. In contrast, DEP youth had increased positive NAcc-left frontal cortex RSFC and reduced positive NAcc-insula RSFC compared to DEP-risk and HC youth (p < .001), suggestive of disorder specific features of depression. Greater depression severity was correlated with disorder-specific amygdala and NAcc RSFC (p < .05). CONCLUSION: RSFC in the amygdala and NAcc may represent selective disorder- and risk-specific markers in youth with, and at familial risk for, depression. Longitudinal studies are needed to determine whether these patterns predict long-term clinical outcomes. PMID- 30274653 TI - Rethinking Lethality in Youth Suicide Attempts: First Suicide Attempt Outcomes in Youth Ages 10 to 24. AB - OBJECTIVE: Although suicide is the second most frequent cause of death in American youth, suicide research has heretofore been confined to convenience samples that represent neither psychiatric nor general populations and that fail to include individuals dying at their first attempts. These limitations were addressed by assembling a youth cohort followed from the first medically recorded attempt (index attempt [IA]). It was hypothesized this approach would more accurately represent the prevalence of completed suicide after an attempt and underscore lethality based on method. METHOD: This study draws from a previously reported retrospective-prospective all-age cohort identified through the Rochester Epidemiology Project. The original 1,490-subject sample included 813 Olmsted County youth 10 to 24 years old (n = 258 male, n = 555 female; 54.6% of total cohort) with IAs from January 1, 1986 through December 31, 2007 and followed until December 31, 2010. RESULTS: Twenty-nine of 813 subjects (3.6%) killed themselves during the study period, with 28 of 29 dying before their 25th birthday and 20 of 28 (71.4%) dying at their first attempt. Despite composing only 31.7% of the cohort (258 of 813), male subjects composed most suicides: 23 of 29 (79.3% of suicides; 8.9% of male subjects) versus 6 of 29 female subjects (20.7% of suicides; 1.1% of female subjects). Eighty-five percent of all IA deaths involved firearms. More than a third of youth-41.2%-lacked a psychiatric history prior to IA. CONCLUSION: These data show that more than half the IAs occurred in youth, with approximately three-fourths of completed youth suicides occurring at the IAs. In parsing cause of IA death in the all-age cohort, the contribution of firearms figured even more prominently in the subsample of youth (85.0%) than in those at least 25 years old (64.3%). The high IA lethality suggests that prevention efforts commencing after the IA are too late for most victims. PMID- 30274651 TI - Atypical Functional Connectivity of Amygdala Related to Reduced Symptom Severity in Children With Autism. AB - OBJECTIVE: Converging evidence indicates that brain abnormalities in autism spectrum disorders (ASDs) involve atypical network connectivity. Given the central role of social deficits in the ASD phenotype, this investigation examined functional connectivity of the amygdala-a brain structure critically involved in processing of social information-in children and adolescents with ASDs, as well as age-dependent changes and links with clinical symptoms. METHOD: Resting-state functional magnetic resonance imaging (rs-fMRI) data from 55 participants with ASDs and 50 typically developing (TD) controls, aged 7 to 17 years, were included. Groups were matched for age, gender, IQ, and head motion. Functional connectivity MRI (fcMRI) analysis was applied to examine intrinsic functional connectivity (iFC) of the amygdala, including cross-sectional tests of age related changes. RESULTS: Direct between-group comparisons revealed reduced functional connectivity between bilateral amygdalae and left inferior occipital cortex, accompanied by greater connectivity between right amygdala and right sensorimotor cortex in the ASD group. This atypical pattern of amygdala connectivity was associated with decreased symptom severity and better overall functioning, as specifically seen in an ASD subgroup with the most atypical amygdala iFC but the least impaired social functioning. Age-related strengthening of amygdala-prefrontal connectivity, as observed in the TD group, was not detected in children with ASDs. CONCLUSION: Findings support aberrant network sculpting in ASDs, specifically atypical integration between amygdala and primary sensorimotor circuits. Paradoxical links between atypical iFC and behavioral measures suggest that abnormal amygdala functional connections may be compensatory in some individuals with ASDs.

AB - Substantial numbers of children and adolescents are treated with second generation antipsychotic medications (SGAs), and the cardiometabolic adverse effects of this medication class have raised concerns.1 In the October 2017 issue of the Journal, Handen et al.2 published a 16-week open-label extension study of youth 6 to 17 years of age with autism spectrum disorder treated with liquid metformin after a 16-week double-blinded, placebo-controlled clinical efficacy trial. The acute-phase and open-label extension trials demonstrated that liquid metformin was well tolerated, and significant improvements in body mass index z scores were observed in the metformin-metformin and placebo-metformin groups.2 Handen et al.2 concluded that metformin can be effective for decreasing weight gain associated with SGA use and maintaining prior improvement in children and adolescents with autism spectrum disorder. PMID- 30274655 TI - Dr. Handen et al. Reply. AB - We thank Dr. Higdon et al. for their interest in our article on metformin and children with autism spectrum disorders (ASD) and for providing information about the MOBILITY study (a Patient-Centered Outcomes Research Institute (PCORI)-funded pragmatic clinical trial to examine the relative effectiveness of metformin plus healthy lifestyle instruction versus healthy lifestyle instruction alone).1 In our October 2017 article,2 we reported the results of a 16-week open-label extension study of a group of 61 children and adolescents with ASD prescribed second-generation antipsychotic medications (SGAs) who previously participated in a randomized controlled trial (RCT) of metformin for management of weight gain. Although Higdon et al. indicated that our study results were encouraging, they believed that the conclusion of the accompanying JAACAP editorial3 stating metformin be considered as an adjunct treatment for any child who is overweight and prescribed SGAs was premature. Instead, they recommended that the results of their current pragmatic trial for children with bipolar disorder (which includes some children with ASD and intellectual disability) would better provide information on relevant moderators and mediators of metformin's effects. Such information would be of use to clinicians in determining whether to prescribe metformin to their patients or to focus on lifestyle changes (or a combination of the 2). PMID- 30274656 TI - Drs.

PMID- 30274657 TI - Antenatal Depression, Epigenetic Gestational Age, Childhood Psychiatric Symptoms, and the Need to Consider the Possible Effects of Unaccounted Confounders. AB - Suarez et al.1 examined associations among antenatal depression, epigenetic gestational age (EGA) as a novel biomarker, and early childhood psychiatric problems. They found that greater severity of antenatal depression predicted lower EGA and that lower EGA predicted total and internalizing problems at 3.7 years of age. Although they included many covariates in their analysis, we believe that the value of the study could have been enhanced by the inclusion of potentially important but unaddressed confounders. PMID- 30274658 TI - Dr. Lahti-Pulkkinen et al. Reply. AB - In their Letter to the Editor, "Antenatal Depression, Epigenetic Gestational Age, Childhood Psychiatric Symptoms, and the Need to Consider the Possible Effects of Unaccounted Confounders," Ghosh et al.1 suggested that unaccounted confounders might explain the associations of child epigenetic gestational age at birth with maternal antenatal depression and child psychiatric problems reported in the article by Suarez et al., "The Epigenetic Clock at Birth: Associations With Maternal Antenatal Depression and Child Psychiatric Problems."2 Although the covariates mentioned in the letter, namely maternal substance use during pregnancy and socioeconomic circumstances, are indeed important factors possibly affecting both maternal and child psychopathology risk, we did not adjust for them in our analyses, as they were not associated with child epigenetic gestational age in our study sample.

AB - Current research points to an increase in the interest in and focus on the age at which the medial end of the clavicle begins and completes union in various populations worldwide. As it currently stands, no information exists for the South African population detailing the age at which this skeletal developmental marker commences or completes union. The aim of this study was to establish the age at which partial and complete unions occur and to find if there is any correlation between the age and the assigned stage score in a South African Black skeletal sample. Paired clavicles of 211 males and females (M = 101, F = 110) with ages ranging between 12 and 45 years from the Raymond A. Dart Collection of Human Skeletons were included. A strong correlation between age and the assigned stage score was observed for both males and females (rs = 0.73). No statistically significant differences between the stage of union at the left and right clavicles were observed (p = 0.9). In this sample, partial union was commonly observed in individuals in their third decade of life; while complete union occurred more often in individuals older than 30 years of age. Assessing and recording the degree of union at the medial end of the clavicle can be a helpful additional age-at-death indicator to use when establishing an age-at-death range. However, overlap and variability between the ages of individuals categorized as either displaying signs of partial or complete union were evident.

AB - BACKGROUND: Current techniques for mapping and ablating cardiac arrhythmias are valuable, but have limitations. We devised a novel method of predicting the origin of a focal arrhythmia wavefront that utilizes conduction velocity (CV), the difference in electrogram timing during arrhythmia (t), and the distance between two points (z) to generate prediction curves which can be applied to an electroanatomic map. The intersection of two such curves predicts the origin of the wavefront. OBJECTIVE: To describe the rationale behind a novel method of arrhythmia mapping and assess its feasibility in a retrospective study of focal arrhythmias. METHODS: We retrospectively studied 12 patients with arrhythmias with focal chamber activation that were successfully mapped and treated with ablation. CV during arrhythmia was measured using electroanatomic mapping software. Values for z and t were calculated for two pairs of points. Two prediction curves were generated and superimposed onto the electroanatomic maps. The distance between the intersection of the two curves and the wavefront origin was recorded. The shortest distance between individual curves and the wavefront origin was also measured. RESULTS: Twenty-four curves were successfully generated in 12 patients. The distance from the intersection of two curves and the wavefront origin was 9.2 +/- 7.7 mm. The shortest distance between individual prediction curves and the wavefront origin was 5.2 +/- 5.2 mm. CONCLUSIONS: Wavefront origins may be predicted by a novel method utilizing a limited number of measurements. Further study of this method requires its integration with an electroanatomical mapping system. PMID- 30274662 TI - Robust Hinfinity control for networked control systems with randomly occurring uncertainties: Observer-based case. AB - This paper investigates the problem of observer-based robust Hinfinity output feedback control for networked control systems (NCSs) with randomly occurring uncertainties, dynamic quantization, and packet loss. It is assumed that the system measurement output will be quantized by a dynamic quantizer and the random packet loss is represented by Bernoulli random binary distribution. In the presence of randomly occurring uncertainties, dynamic quantization, and packet loss, the attention of this research is focused on the design of observer-based robust Hinfinity output feedback controller such that the resulting system is stochastically stable with the prescribed Hinfinity noise attenuation level. The sufficient condition for the existence of such output feedback controller is expressed in the form of linear matrix inequality (LMI). Simulation results of two illustrative examples are proposed to demonstrate the effectiveness of the developed design method.

AB - This paper proposes a stabilization criterion for a fractional-order plant involving interval uncertainties in the coefficients using fractional-order PDMU controller with a filter. The vertex functions of the value set corresponding to the characteristic function of the closed loop system are determined by the law of Minkowski sum. The finite test frequency interval is offered to simplify the calculation of the test for the stabilization. The analytical method to test the position relationship between the origin and the value set is investigated within the finite test frequency interval. Then, the stabilization criterion with an analytical method is provided based on the zero exclusion principle. Finally, three examples are given to verify the effectiveness of this criterion. PMID- 30274665 TI - The Relationship Between Personality Characteristics, Tenure, and Intent to Leave Among Emergency Nurses. AB - INTRODUCTION: Emergency nursing turnover rates are high in the United States. Little is known about the role of personality characteristics in the turnover decisions of emergency nurses. Intent to leave is often measured to determine the likelihood of turnover versus retention of employees. The aim of this study is to examine the relationship among personality characteristics, employment tenure, and intent to leave among emergency nurses. METHODS: Using a descriptive, correlational design, data were collected using the HEXACO-PI-R personality inventory and demographic data. Participants included 406 current and former emergency nurses with employment tenure ranging from < 1 year to > 10 years. RESULTS: Analysis indicated a significant relationship between years of tenure and the traits of Honesty/Humility (P = 0.003), Emotionality (P = 0.001), Agreeableness (P = 0.02), and Openness (P = 0.05). When factoring in intent to leave, nurses with tenure longer than 10 years have significantly higher levels of Honesty/Humility (P = 0.001) and a significantly lower level of Emotionality (P = 0.011) than nurses with tenure of less than 2 years and intent to leave within 1 year. Finally, all 406 emergency nurses in this dataset had similarity among the 6 measured personality dimensions. DISCUSSION: This study found similarities in personality characteristics for all 406 study participants, with significant differences related to career tenure for some dimensions. This type of knowledge might provide administrators with details of important characteristics to foster which may have a positive impact on retention.

PMID- 30274667 TI - Hide and seek: Directing top-down attention is not sufficient for accelerating conscious access. AB - At any moment in time, we have a single conscious visual experience representing a minute part of our visual world. As such, the visual input stimulating our retinae is in continuous competition for reaching conscious access. Many complex cognitive operations can only be applied to consciously accessible visual information, thereby raising the question whether humans have the ability to select which parts of their visual input reaches consciousness. Top-down attention allows humans to flexibly assign more processing resources to certain parts of our visual input, making it a likely mechanism to volitionally bias conscious access. Here, we investigated whether directing top-down attention to a particular location or feature accelerates conscious access of an initially suppressed visual stimulus at the attended location, or of the attended feature. We instructed participants to attend a spatial location (Experiment 1) or color (Experiment 2) for a speeded discrimination task, using a highly predictive cue. The predictive cues were highly effective in prompting sustained attention towards the cued location or color, as evidenced by faster discrimination of cued relative to uncued targets. We simultaneously measured detection times to interocularly suppressed probes that were either of the cued (i.e., attended) color/location or not, and were visually distinct from the targets used for the discrimination task. Despite our successful manipulation of top-down attention, suppressed probes were not released from suppression faster when they were presented at the attended location, or in the attended color. In contrast, when observers were cued to attend a color for locating targets of an ill-defined shape (inciting a broader attentional template), we did observe faster conscious access of probes in the attended color (Experiment 3). We discuss our findings in light of the specificity of attentional templates, and the inherent limitations that this poses for top-down attentional biases on conscious access. PMID- 30274668 TI - The measurement of episodic foresight: A systematic review of assessment instruments. AB - Prospection, or thinking about the future, is currently a topic of significant interdisciplinary research interest. Episodic foresight is considered a complex form of prospection that enables people to generate mental models of future scenarios with which to guide actions. In this article, we systematically review the available episodic foresight measurement instruments. PubMed and PsycInfo were searched through July, 2017 and manual searches of published reviews and snowball searches of included studies were also performed. The initial search yielded 970 records after the removal of duplicates, of which 363 underwent full text screening. Studies that did not measure the imagination of future scenarios in adult humans, or that were not reported in English, were excluded. The review consists of 303 articles classified into two broad categories, content measures and generation measures, that were further subdivided into one or more of six subcategories: (i) phenomenology (60%); (ii) examination (49%); (iii) fluency (12%); (iii) reaction time (12%); sentence completion (5%); and thought sampling (2%). We catalogue the available instruments in these sections, and provide a summary overview of each category. Following phenomenological measures, the adapted Autobiographical Interview and measures of specificity were the most frequently used instruments. We conclude that none of the available instruments have been appropriately validated for use, and therefore suggest caution with the use of any of the included measures. The development of behavioural measures designed to capture degrees of episodic foresight ability in functionally relevant contexts among humans would provide a major advance over the currently available instruments.

Taxidermied animals, fauna preserved in glass jars, skeletons, and fossilized shells were all part of this collection. The research showed that those animals were used by libertarian teachers in science classes in a school created by republicans and freemasons in the transition from the 19th to the 20th century. PMID- 30274681 TI - Renal transplant recipients receiving loop diuretic therapy have increased urinary tract infection rate and altered medullary macrophage polarization marker expression. AB - Loop diuretics deplete the renal cortico-medullary salt gradient that has recently been established as a major modulator of immune responses. Renal transplant recipients suffer from a markedly increased rate of urinary tract infections (UTIs). Whether diuretic therapy affects renal macrophage polarization in the human kidney graft and the incidence of UTI have not been reported. In a cohort of 112 adult renal allograft recipients, loop diuretic therapy significantly correlated with the rate of UTI during five years after transplantation in uni- and multivariable regression analysis. The M1 macrophage marker human leukocyte antigen-DR (HLA-DR) and the M2 macrophage marker CD206 co localized with the pan-macrophage marker CD68 in the kidney graft. Both were more common in renal medulla than cortex. With increasing loop diuretic dose, the renal medullary M1/M2 macrophage marker ratio decreased in early surveillance biopsies of this cohort. In vitro, the sodium chloride concentration dose dependently increased monocyte chemotactic cytokine CCL2 production in human myeloid and renal tubular epithelial cells. More CCL2 was detected in the renal medulla than cortex of the kidney grafts. However, in patients receiving loop diuretic therapy, the renal cortico-medullary CCL2 gradient was diminished and CCL2 serum levels decreased significantly. Thus, diuretic therapy associated with increased bacteriuria and leukocyturia after kidney transplantation and a decreased M1/M2 macrophage marker ratio in the renal medulla. Hence, adjustment of diuretic therapy should be investigated further as a possible approach in patients with frequent UTIs.

AB - This paper reviewed the 2002 guidelines established by the National Federation of Cancer Centres. A group of experts nominated by the 3 French Societies involved in the treatment of cancer pain (AFSOS, SFAP, SFETD), established new guidelines ratios for morphine switching and/or changing of route of administration, in patients for whom either pain was not adequatly managed or adverse effects were unbearable. After a rapid reminder of the pharmacokinetics and metabolism properties of morphine, experts explained why the theory of opioid rotation (oxycodone, hydromorphone, fentanyl, methadone, tapentadol) using fixed equianalgesic ratios is not any more appropriate for a secure clinical practice. In the light of recent publications enhancing our knowledge on the efficacy of new drug switching ratios and for changing the route of administration of morphine, the group of experts recommended to use reconsidered switching ratios favoring security upon efficacy, to minimize overdosing and adverse effects. Consequently, after the new conversion ratio (using slow release opioids) was applied, a second titration should be done by means of normal release rescue formulations for breakthrough pain episodes. A smartphone App. OpioConvert(r) will be available for rapid and secure dose conversions. PMID- 30274683 TI - Development of a Tissue-Mimicking Phantom of the Brain for Ultrasonic Studies. AB - Constructing tissue-mimicking phantoms of the brain for ultrasonic studies is complicated by the low backscatter coefficient of brain tissue, causing difficulties in simultaneously matching the backscatter and attenuation properties. In this work, we report on the development of a polyvinyl alcohol based tissue-mimicking phantom with properties approaching those of human brain tissue. Polyvinyl alcohol was selected as the base material for the phantom as its properties can be varied by freeze-thaw cycling, variations in concentration and the addition of scattering inclusions, allowing some independent control of backscatter and attenuation. The ultrasonic properties (including speed of sound, attenuation and backscatter) were optimized using these methods with talc powder as an additive. It was determined that the ultrasonic properties of the phantom produced in this study are best matched to brain tissue in the frequency range 1 3 MHz, indicating its utility for laboratory ultrasonic studies in this frequency range. PMID- 30274682 TI - Effect of Molecular Weight on Sonoporation-Mediated Uptake in Human Cells. AB - Ultrasound-induced microbubble destruction can enhance drug delivery to cells. The molecular weight of therapeutic compounds varies significantly (from <1 kDa for small molecule drugs, to 7-15 kDa for siRNAs/miRNAs, to >1000 kDa for DNA plasmids). Therefore, the objective of this study was to determine the relationship between uptake efficiency and molecular weight using equal molar concentrations. Uptake efficiency of fluorescent compounds with different molecular weights (0.3, 10 and 2000 kDa) was explored in vitro using human cardiac mesenchymal cells and breast cancer cells exposed to microbubbles and 2.5 MHz ultrasound pulses. Uptake by viable cells was quantified using flow cytometry. After correction for the fluorescence yield of each compound, there was a significant size-dependent difference in fluorescence intensity, indicating an inverse relationship between size and uptake efficiency. These results suggest that diffusion of therapeutic compounds across permeabilized cell membranes may be an important mechanism for ultrasound-mediated drug delivery. PMID- 30274684 TI - Neuroradiological findings in patients with "non-lesional" focal epilepsy revealed by research protocol. AB - AIM: To evaluate whether a dedicated epilepsy research protocol with expert image re-evaluation can increase identification of patients with lesions and to attempt to ascertain the potential reasons why lesions were not identified previously on earlier clinical magnetic resonance imaging (MRI). MATERIALS AND METHODS: Forty three patients (26 female) with focal refractory epilepsy who had failed at least two trials of anti-epileptic drug treatments were studied. Patients were recruited prospectively into the study if previous clinical MRI was deemed to be "non-lesional" by the clinicians involved in the initial assessment. Three dimensional (3D) T1-weighted (T1W), T2-weighted (T2W), T2 fluid-attenuated inversion recovery (T2-FLAIR) sequences, and two-dimensional (2D) coronal T1-/T2W FLAIR were assessed by a neuroradiologist, including the previous clinical MRI of individual patients. RESULTS: Twenty-nine or 43 (67%) patients remained MRI negative after scanning with the epilepsy-dedicated protocol and image reappraisal by expert consultant neuroradiologists; however, 14/43 (33%) patients were found to have potentially epileptogenic brain lesions. The lesion that most frequently escaped the attention of clinicians was hippocampal sclerosis (nine cases, of which two had an additional focal cortical dysplasia, FCD), followed by single FCDs (two cases), and others including gliosis, encephalocoele, and amygdala enlargement (one case each). Eleven of the 14 (79%) previously "non lesional" patients had electroencephalogram (EEG) imaging-concordant localisation features, rendering them potential candidates for resective surgery. CONCLUSIONS: The primary factors explaining the newly identified lesions were the choice of MRI sequences, imaging parameters, data quality, lesion not reported (human factor), and loss of information through incomplete documentation. It is important for all clinicians to proceed meticulously in the detailed assessment of epilepsy-dedicated in-vivo MRI and discuss difficult patient cases in multidisciplinary team meetings. PMID- 30274685 TI - MiR-137 suppresses migration and invasion by targeting EZH2-STAT3 signaling in human hepatocellular carcinoma. AB - BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most common and aggressive human malignancies and many cell-intrinsic identities and extrinsic epigenetic factors influence the metastatic potential of HCC cells. MicroRNA-137 is often found to be acting as tumor suppressors, however, how miR-137 involved in the metastasis progression in human HCC remains unclear. METHOD: QPCR was performed to detect the miR-137 mRNA levels in HCC cell linesand normal liver cell line HL7702.Then transwell assay and wound-healing assay were determined to investigate the motility of HCC cells introduced into lentivirus to ectopically upregulate endogenous miR-137 and EAH2 expressions. Targeting of enhancer of zeste homolog 2 (EZH2) gene by miR-137 in HCC was assessed by dual-luciferase activity assay and qPCR. Western blot was applied to explore the mechanism. In vivo, lung metastasis were evaluated using a mice tail vein injection model. RESULTS: In this study, we found that miR-137 is decreased in HCC cell lines and had an inhibitory effect on HCC migration and invasion in vitro. EZH2 was a direct downstream target gene of miR-137 in HCC and miR-137 suppressed invasion and migration by targeting EZH2-STAT3 signaling in HCC cells. Furthermore, EZH2 overexpression reversed the miR-137 mimics-induced inhibitory effects on migration and invasion of HCC cells. In addition, miR-137 inhibited lung metastasis of HCC in vivo by targeting EZH2-STAT3 signaling. CONCLUSION: MiR-137 suppressed migration and invasion by targeting EZH2-STAT3 signaling pathway in HCC cells in vitro and in vivo, suggesting miR-137-EZH2-STAT3 may be a potential therapeutic target for treatment of human hepatocellular carcinoma. PMID- 30274686 TI - Hypoxia inducible factor 1alpha in hepatocellular carcinoma with cirrhosis: Association with prognosis. AB - BACKGROUND: Hypoxia inducible factor 1alpha (HIF-1alpha) is a protein related with carcinogenesis and metastasis in many tumors. However, little is known about the prognostic value of HIF-1alpha in hepatocellular carcinoma (HCC) patients with cirrhosis. METHODS: Clinical-pathological information and follow-up data were collected from HCC (n = 419) and chronic hepatitis (n = 49) patients. HIF 1alpha expression was scored based on the percentage of immunohistochemical staining. Correlations between HIF-1alpha expression and clinical features were evaluated by Chi-square test. And survival analysis was performed by multivariate Cox regression analysis. RESULTS: In cirrhosis patients, the frequency of HIF 1alpha positive expression in HCC was higher than in chronic hepatitis (P = 0.002). HIF-1alpha positive expression was significantly associated with vascular invasion (P = 0.002), TNM stage (P = 0.005), HBV infection (P = 0.005), tumor size (P = 0.025) and portal vein tumor thrombus (P = 0.001) in HCC with liver cirrhosis. While, in cirrhosis-free patients, HIF-1alpha positive expression had a significant correlation with vascular invasion (P = 0.039) and AFP value (P = 0.001) in. HIF-1alpha "positive" had decreased overall survival compared to HIF 1alpha "negative" patients and this was an independent adverse prognostic factor (multivariable analysis P = 0.001) for HCC patients with cirrhosis, but not for cirrhosis-free patients. CONCLUSIONS: Our results suggested that HIF-1alpha served as a poor prognostic factor for HCC patients with cirrhosis. PMID- 30274687 TI - Obesity and bowel cancer: from molecular mechanisms to interventions. AB - The purpose of this review article is to examine the evidence of the mechanisms linking obesity with bowel cancer risk and to comment on the development of interventions that may lower risk of this common age-related disease. The choice of topics for inclusion reflects my personal research on the etiology and prevention of bowel cancer over the past 3 decades. I have cited literature which addresses each of these topics, but because of the breadth of the review article, I have not attempted to do this systematically. The accumulation of genomic damage which leads to colorectal (bowel) cancer (CRC) is influenced by the balance between damage acquisition through environmental exposures and endogenous factors/processes and the effectiveness of genomic repair mechanisms. There is now convincing evidence that obesity is associated with increased bowel cancer risk, and this increased risk is apparent even among those with Lynch syndrome who are genetically predisposed to the disease. It seems likely that genomic damage resulting from obesity-related inflammation is a key driver of colorectal tumorigenesis, but mechanisms may also include altered insulin/insulin-like growth factor 1 signaling which may give tumor cells a competitive advantage. The importance of inflammation as a mediator of the effects of obesity is supported by the fall in CRC risk which follows sustained exposure to nonsteroidal anti inflammatory drug such as aspirin and the abrogation of the excess CRC risk in obese patients with Lynch syndrome who were randomized to aspirin. Because the available evidence about the effects of weight loss in the obese on CRC risk is limited, this should be a high priority for future research. In the meantime, to lower the global CRC burden, it would be prudent to institute effective public measures to reduce the development of obesity and to enable those who are obese to lose weight.

AB - This study examines the relationship between productive activities and cognitive decline among older adults aged 50 years and over in China and whether this relationship varies by gender and urban/rural residence using a sample of 13,596 respondents from three waves of the China Health and Retirement Longitudinal Study. Results from Generalized Estimation Equations show that caring for grandchildren, caring for a spouse, informal helping and formal volunteering are associated with reduced risk of cognitive decline over a two-year period. In addition, the types of productive activities that are most beneficial for cognition vary by gender and urban/rural residence. Caring for grandchildren and volunteering are most beneficial for urban women, informal helping is most beneficial for urban men, and paid employment is most beneficial for rural men. PMID- 30274689 TI - Periprosthetic bone quality affects the fixation of anatomic glenoids in total shoulder arthroplasty: in vitro study. AB - BACKGROUND: Glenoid loosening, a common complication of shoulder arthroplasty, could relate to implant design and bone quality. However, the role of bone density has not been tested experimentally yet. In this study, tests on cadaveric specimens of varying bone density were performed to evaluate the effects of bone quality on loosening of typical anatomic glenoid implants. METHODS: Cadaveric scapulae scanned with a quantitative computed tomography scanner to determine bone mineral density (BMD) were implanted with either pegged or keeled cemented glenoid components and tested under constant glenohumeral load while a humeral head component was moved cyclically in the inferior and superior directions. Implant superior and inferior edge lifting, defined as displacement from the underlying bone, was measured with linear variable differential transducers until we reached 23,000 test cycles, and statistical testing was performed for differences in edge lifting due to implant design and related to periprosthetic BMD. RESULTS: Edge lifting was statistically significant at all time points, but on average, implant design had no effect. Lifting was highest in specimens in which BMD below the lifting edge was lower, with trends of increased displacement with decreased BMD. CONCLUSIONS: Implant lifting was greater in glenoids of lower bone density for both implant designs. This finding suggests that fixation failure will most likely occur in bone of lower density and that the fixation design itself may play a secondary role. PMID- 30274690 TI - Structure assisted impurity profiling for rapid method development in liquid chromatography. AB - The use of trial-and-error principles is a frequently used technique in method development. This may lead to the fact that analytical methods are used routinely without developers and users having gained extensive and well-founded knowledge about the robustness of their analytical methods and the influence of critical key parameters. This very often leads to unnecessary problems for analysts. A simple way in reverse phase chromatography to simulate the effects of pH value changes on the separation and retention of substances is the pH-dependent calculation of the logD value. With this tool, model substances were used to show how the time requirement for method screening can be considerably reduced in silico and, in addition, extended knowledge about the separation mechanics can be generated. Based on this knowledge, a new method for the purity analysis of carbamazepine was developed within a very short period of time, which improves the performance of the official Ph.Eur. monograph by far. Furthermore, the extremely high robustness of the new method was demonstrated. Using the logD based approach, Quality-by-Design is applied in method development and kept pace with the increasing requirements of regulatory authorities in the pharmaceutical industry. PMID- 30274691 TI - Development of a quantitative method for four photocyanine isomers using differential ion mobility and tandem mass spectrometry and its application in a preliminary pharmacokinetics investigation. AB - Photodynamic therapy (PDT) has been accepted as an alternative treatment for cancer, and its target specificity can be achieved by controlling the location at which light activates the photosensitizer. Photocyanine, a novel anticancer phthalocyanine-based photosensitizer, is a mixture of 4 cis-isomers of a series of synthetic products, and accordingly, it is essential to verify whether there are differences in pharmacokinetics among the four isomers for clinical application, which requires reliable analytical methods to measure the plasma concentrations of the four isomers. An efficient LC-MS/MS method coupled with differential mobility spectrometry (DMS) for the simultaneous quantification of the four photocyanine isomers in human plasma was developed and validated herein. This method had a limit of quantification of 10 ng mL-1 for each isomer and showed stable and reproducible inter- and intra-day results. Use of this method in preliminary pharmacokinetic studies in patients with esophageal cancer showed that the exposure and distribution of the four isomers were different, which had not been found in previous studies. The present research revealed that DMS was an effective tool for isomeric quantitation and that LC-DMS-MS/MS presented robust and reliable in biomatrix analysis. The method significantly improved peak separation and sensitivity compared with that of other LC-MS-based methods.

AB - A novel monolithic column based on the copolymerization of ethylene dimethacrylate and a deep eutectic solvent (DES), which composed of chlorocholine chloride and itaconic acid, was developed for capillary electrochromatography (CEC). The structure and morphology of the obtained monolithic column was characterized by Fourier transform infrared spectra and scanning electron microscopy, which showed a porous monolithic structure with good permeability. The influence of pH value and acetonitrile content on electroosmotic flow (EOF) of DES-based monolithic column was investigated. The DES-based monolithic column was used as the separation column of CEC and exhibited excellent performance for the separation of neutral compounds, phenols, toluidines, nucleosides, nucleotide bases and alkaloids. The retention mechanism might be attributed to synergistic effect of hydrophobic interaction, hydrogen bond interaction and electronic interaction. The DES-based monolithic column showed good repeatability with relative standard deviations of migration time less than 0.80%, 2.15%, 4.26% and 3.08% for intra-day, inter-day, column-to-column and batch-to-batch, respectively. Thus, organic polymer monolithic columns with DESs as functional monomers are a promising option in chromatographic separation. PMID- 30274693 TI - Analysis of degradation products of nerve agents via post-pentafluorobenzylation liquid chromatography-tandem mass spectrometry. AB - In the work reported here, a screening procedure was developed for the detection and identification of RMPAs (nerve agent degradation products) after pentafluorobenzylation using liquid chromatography-tandem mass spectrometry (LC MS/MS). With this method, all RMPAs, including highly hydrophilic types such as methylphosphonic acid (MPA) and ethyl methylphosphonic acid (EMPA), were sufficiently retained in commonly used reversed-phase columns (retention times: 15.7 and 11.0 min.), and the presence of RMPAs was determined more efficiently than with the conventional direct LC-MS/MS method. The detection limits of RMPAs using this approach (<33 ng) were mostly superior to those observed with direct LC-MS/MS (<74 ng) and gas chromatography-mass spectrometry (GC-MS) after pentafluorobenzylation (<1.1 MUg). The applicability of newly developed method toward real samples was evaluated via recovery tests involving urine/serum and wipe tests on various surfaces.

Efficiency of breast-conserving treatments (BCT) compared to mastectomies is equivalent. BCT is better accepted but can cause breast deformity, thus further operations. Oncoplastic surgery aims at conserving an acceptable shape to the breast. It ranges from simple remodeling to more complex techniques modifying the width of the breast. According to the quadrant to treat (inner upper, outer upper, inner lower, outer lower, union of quadrants, tumors of the nipple-areola complex, tumors of the inframammary fold), according to the proximity of the tumor to the nipple, and to the size of the breast and tumor, various techniques are displayed. Few touch ups are necessary. Symmetry is managed during the initial operation or after.

AB - Vesicular acetylcholine transporter (VAChT) is a reliable biomarker for assessing the loss of cholinergic neurons in the brain that is associated with cognitive impairment of patients. 5-Hydrotetralin compound (+/-)-5-OH-VAT is potent (Ki = 4.64 +/- 0.32 nM) and selective for VAChT (>1800-fold and 398-fold for sigma1 and sigma2 receptor, respectively) with favorable hydrophilicity (LogD = 1.78), while (-)-5-OH-VAT originally serves as the radiolabeling precursor of (-)-[18F]VAT, a promising VAChT radiotracer with a logD value of 2.56. To evaluate (-)-5-OH [18F]VAT as a radiotracer for VAChT, we performed in vitro binding assay to determine the potency of the minus enantiomer (-)-5-OH-VAT and plus enantiomer (+)-5-OH-VAT, indicating that (-)-5-OH-VAT is a more potent VAChT enantiomer. Radiosynthesis of (-)-5-OH-[18F]VAT was explored using three strategies. (-)-5-OH [18F]VAT was achieved with a good yield (24 +/- 6%) and high molar activity (~37 GBq/umol, at the end of synthesis) using a microwave assisted two-step one-pot procedure that started with di-MOM protected nitro-containing precursor (-)-6. MicroPET studies in the brain of nonhuman primate (NHP) suggest that (-)-5-OH [18F]VAT readily penetrated the blood brain barrier and specifically accumulated in the VAChT-enriched striatum with improved washout kinetics from striatum compared to [18F]VAT. Nevertheless, the lower target to non-target ratio may limit its use for in vivo measurement of the VAChT level in the brain. PMID- 30274696 TI - One-Stage Repair of Adult Aortic Coarctation and Concomitant Cardiac Diseases: Ascending to Abdominal Aorta Extra-Anatomical Bypass Combined with Cardiac Surgery. AB - BACKGROUND: To evaluate one-stage repair with ascending to abdominal aorta extra anatomical bypass combined with cardiac surgery for adult aortic coarctation (COA) concomitant with cardiac diseases. METHODS: Between February 2009 and September 2016, 24 consecutive patients (79.17% male, mean age 36.04+/ 13.67years) with COA and concomitant cardiac diseases underwent one-stage repair (ascending to abdominal aorta extra-anatomical bypass combined with cardiac surgery). Two patients who underwent off-pump coronary artery surgery combined with ascending to abdominal aorta bypass did not require cardiopulmonary bypass. Twenty-two patients underwent one-stage repair under cardiopulmonary bypass. RESULTS: No in-hospital mortality was observed. There was a significant reduction in baseline systolic blood pressure from 159.80+/-23.58 to 127.0+/-6.86mmHg. Mean upper-lower limb blood gradient pressure decreased significantly from 37.80+/ 8.73 to 11.47+/-2.12mmHg after surgery. Two patients required prolonged mechanical ventilation for respiratory dysfunction. One patient needed temporary continuous renal replacement therapy. No re-exploration for bleeding and gastrointestinal complications was needed. There was no postoperative paraplegia or permanent neurological abnormalities. Grafts were patent for all patients and no graft-related complications were observed in the hospital. Median follow-up was 41.50 months [interquartile range (IQR) 16.75-64.50 months] and 6-year survival was 76.39%. Median number of antihypertensive drugs was 0 (IQR 0-1), which was a significant reduction compared with preoperative drugs (2, IQR 1-3). CONCLUSIONS: Ascending to abdominal extra-anatomical aorta bypass combined with cardiac surgery is a safe and effective one-stage repair technique for patients with COA concomitant with cardiac diseases.

PMID- 30274699 TI - Radiofrequency-induced Thermo-chemotherapy Effect Versus a Second Course of Bacillus Calmette-Guerin or Institutional Standard in Patients with Recurrence of Non-muscle-invasive Bladder Cancer Following Induction or Maintenance Bacillus Calmette-Guerin Therapy (HYMN): A Phase III, Open-label, Randomised Controlled Trial. AB - BACKGROUND: There is no effective intravesical second-line therapy for non-muscle invasive bladder cancer (NMIBC) when bacillus Calmette-Guerin (BCG) fails. OBJECTIVE: To compare disease-free survival time (DFS) between radiofrequency induced thermo-chemotherapy effect (RITE) and institutional standard second-line therapy (control) in NMIBC patients with recurrence following induction/maintenance BCG. DESIGN, SETTINGS, AND PARTICIPANTS: Open-label, phase III randomised controlled trial accrued across 14 centres between May 2010 and July 2013 (HYMN [ClinicalTrials.gov: NCT01094964]). INTERVENTION: Patients were randomly assigned (1:1) to RITE (60min, 40mg mitomycin-C, 42+/-2 degrees C) or control following stratification for carcinoma in situ (CIS) status (present/absent), therapy history (failure of previous induction/maintenance BCG), and treatment centre. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Primary outcome measures were DFS and complete response (CR) at 3 mo for the CIS at randomisation subgroup. Analysis was based on intention-to-treat. RESULTS AND LIMITATIONS: A total of 104 patients were randomised (48 RITE: 56 control). Median follow-up for the 31 patients without a DFS event was 36 mo. There was no significant difference in DFS between treatment arms (hazard ratio [HR] 1.33, 95% confidence interval [CI] 0.84-2.10, p=0.23) or in 3-mo CR rate in CIS patients (n=71; RITE: 30% vs control: 47%, p=0.15). There was no significant difference in DFS between treatment arms in non-CIS patients (n=33; RITE: 53% vs control: 24% at 24 mo, HR 0.50, 95% CI 0.22-1.17, p=0.11). DFS was significantly lower in RITE than in control in CIS with/without papillary patients (n=71; HR 2.06, 95% CI 1.17-3.62, p=0.01; treatment-subgroup interaction p=0.007). Disease progression was observed in four patients in each treatment arm. Adverse events and health related quality of life between treatment arms were comparable. CONCLUSIONS: DFS was similar between RITE and control. RITE may be a second-line therapy for non CIS recurrence following BCG failure; however, confirmatory trials are needed. RITE patients with CIS with/without papillary had lower DFS than control. HYMN highlights the importance of the control arm when evaluating novel therapies. PATIENT SUMMARY: This study did not show a difference in bladder cancer outcomes between microwave-heated chemotherapy and standard of care treatment. Papillary bladder lesions may benefit from microwave-heated chemotherapy treatment; however, more research is needed. Both treatments are similarly well tolerated. PMID- 30274701 TI - The Cancer Immunogram as a Framework for Personalized Immunotherapy in Urothelial Cancer. AB - CONTEXT: The abysmal outlook of urothelial cancer (UC) has changed with the introduction of immunotherapy. Still, many patients do not respond and distinctive biomarkers are currently lacking. The rise of this novel armamentarium of immunotherapy treatments, in combination with the complex biology of an immunological tumor response, warrants the development of a comprehensive framework that can provide an overview of important immunological processes at play in individual patients. OBJECTIVE: To develop a comprehensive framework based on tumor- and host-specific parameters to understand immunotherapy response in UC. This framework can inform rational, biology-driven clinical trials and ultimately guide us toward individualized patient treatment. EVIDENCE ACQUISITION: A literature review was conducted on UC immunotherapy, clinical trial data, and biomarkers of response to checkpoint inhibition. EVIDENCE SYNTHESIS: Here, we propose a UC immunogram, based on currently available clinical and translational data. The UC immunogram describes several tumor- and host-specific parameters that are required for successful immunotherapy treatment. These seven parameters are tumor foreignness, immune cell infiltration, absence of inhibitory checkpoints, general performance and immune status, absence of soluble inhibitors, absence of inhibitory tumor metabolism, and tumor sensitivity to immune effectors. CONCLUSIONS: Longitudinal integration of individual patient parameters may ultimately lead to personalized and dynamic immunotherapy, to adjust to the Darwinian forces that drive tumor evolution. Incorporating multiparameter biomarkers into quantitative predictive models will be a key challenge to integrate the immunogram into daily clinical practice. PATIENT SUMMARY: Here, we propose the urothelial cancer immunogram, a novel way of describing important immunological characteristics of urothelial cancer patients and their tumors. Seven characteristics determine the chance of having an immunological tumor response. Using this immunogram, we aim to better understand why some patients respond to immunotherapy and some do not, to ultimately improve anticancer therapy. PMID- 30274702 TI - Primary Whole-gland Cryoablation for Prostate Cancer: Biochemical Failure and Clinical Recurrence at 5.6 Years of Follow-up. AB - : We retrospectively evaluated complications and functional and oncologic outcomes of 94 consecutive men who underwent primary whole-gland cryoablation for localized prostate cancer (PCa) from 2002 to 2012. Kaplan-Meier and multivariable Cox regression analyses were performed using a landmark starting at 6 mo of follow-up. In total, 75% patients had D'Amico intermediate- (48%) or high- (27%) risk PCa. Median follow-up was 5.6 yr. Median time to prostate-specific antigen (PSA) nadir was 3.3 mo, and 70 patients reached PSA <0.2ng/ml postcryoablation. The 90-d high-grade (Clavien Grade IIIa) complication rate was 3%, with no rectal fistulas reported. Continence and potency rates were 96% and 11%, respectively. The 5-yr biochemical failure-free survival (PSA nadir+2ng/ml) was 81% overall and 89% for low-, 78% for intermediate-, and 80% for high-risk PCa (p=0.46). The median follow-up was 5.6 and 5.1 yr for patients without biochemical failure and with biochemical failure, respectively. The 5-yr clinical recurrence-free survival was 83% overall and 94% for low-, 84% for intermediate-, and 69% for high-risk PCa (p=0.046). Failure to reach PSA nadir <0.2ng/ml within 6 mo postcryoablation was an independent predictor for biochemical failure (p=0.006) and clinical recurrence (p=0.03). The 5-yr metastases-free survival was 95%. Main limitation is retrospective evaluation. Primary whole-gland cryoablation for PCa provides acceptable medium-term oncologic outcomes and could be an alternative for radiation therapy or radical prostatectomy. PATIENT SUMMARY: Cryoablation is a safe, minimally-invasive procedure that uses cold temperatures delivered via probes through the skin to kill prostate cancer (PCa) cells. Whole-gland cryoablation may offer an alternative treatment option to surgery and radiotherapy. We found that patients had good cancer outcomes 5 yr after whole gland cryoablation, and those with a prostate-specific antigen value >=0.2ng/ml within 6 mo after treatment were more likely to have PCa recurrence.

PMID- 30274704 TI - Results and functional outcomes of en-bloc resection and vascular reconstruction in extremity musculoskeletal tumors. AB - OBJECTIVES: This paper aims to evaluate the extremity function and vascular outcome after limb-sparing surgery for extremity musculoskeletal tumors invading vascular structure required reconstruction. METHODS: Of the 507 patients with musculoskeletal tumors, who underwent surgery between 2004 and 2007, 17 (3,3%) patients with major vessel involvement were included in the study. The mean age was 37.8 +/- 14.5, with a female/male ratio of 8/9. Thirteen (76.4%) patients had Stage IIb disease, and 2 (11,7%) patients had Stage III disease. In 2 (11,7%) patients have locally aggressive tumor that had Stage 3. Fifteen (88.2%) of the cases involved lower extremity, whilst 2 (11.8%) of them involved upper extremity. An arterial reconstruction was carried out in all patients. Wide tumor resection and endoprosthetic reconstruction were performed in 6 (35.2%) patients. Other 11 (65.8%) patients were treated with wide resection and soft tissue reconstruction. Postoperative data included; perioperative morbidities such as bleeding, infection, graft thrombosis, rupture, metastatic local recurrence and mortality. Ankle brachial index (ABI) and color-flow-duplex-scan (CFDS) were done at the final follow-up of the study, in order to prove the efficacy of reconstruction. Functional outcome was evaluated with International Society of Limb Salvage (ISOLS) criteria. RESULTS: The mean follow-up was of 39 months (range 3-120). Perioperative complications were arterial graft thrombosis occurred in 3 (17.6%) patients treated acutely with thrombectomy, uncontrolled deep wound infection occurred in 2 patients whom extremities were amputated. The most frequent complication after surgery was limb edema according to possibly venous and lymphatic obstruction, staged as C1, C2 and C3 disease was established in 6 patients (two patients in each group), and 1 patient was classified as C6 disease. Three (17.6%) patients had local recurrence (1/3 patient died and 2/3 (11.7%) patients underwent transfemoral amputation). At the last follow-up, 9 (52.9%) patients were alive without evidence of disease, 8 (47.1%) patients were died due to primary disease. There were 8 (47.1%) patients alive with an intact limb. Although functional outcome scores were satisfactory, emotional acceptance scores were low. The limb salvage probability was 74.0%. CONCLUSION: Limb-sparing oncological surgery in musculoskeletal tumors with vascular invasion provides a satisfactory limb function, which may lead to an improved life quality. Arterial reconstruction has a high rate of patency in the long term. The surgeon should be aware of early perioperative complication related to vascular reconstruction and infection that effect on the rate of extremity survival.

AB - Recent research has shown that children's sense of fairness is shaped in part by cultural practices, values, and norms. However, the specific social factors that motivate children's fairness decisions remain poorly understood. The current study combined an ethnographic approach with experimental tests of fairness (the Inequity Game) in two Chinese schools with qualitatively different practices and norms. In the "University school," children received explicit moral instruction on fairness reinforced by adults when supervising children's activities. By contrast, in the "Community school," children received less formal moral education and little adult supervision during play time, but norms of cooperation and fairness emerged through informal interactions with peers and other members of the community. Contrary to our predictions, children in both schools (N = 66) rejected both disadvantageous and advantageous allocations of resources in the test trials. However, in the very first practice trials, children from the Community school tended to reject all inequalities, whereas children from the University school tended to accept inequalities. We draw on the ethnographies of the schools to interpret these results, concluding that, despite the similarities in the experimental results, different motivations and social factors likely underlie the rejection of inequality in the two schools. PMID- 30274705 TI - DynBench3D, a Web-Resource to Dynamically Generate Benchmark Sets of Large Heteromeric Protein Complexes. AB - Multi-protein machines are responsible for most cellular tasks, and many efforts have been invested in the systematic identification and characterization of thousands of these macromolecular assemblies. However, unfortunately, the (quasi) atomic details necessary to understand their function are available only for a tiny fraction of the known complexes. The computational biology community is developing strategies to integrate structural data of different nature, from electron microscopy to X-ray crystallography, to model large molecular machines, as it has been done for individual proteins and interactions with remarkable success. However, unlike for binary interactions, there is no reliable gold standard set of three-dimensional (3D) complexes to benchmark the performance of these methodologies and detect their limitations. Here, we present a strategy to dynamically generate non-redundant sets of 3D heteromeric complexes with three or more components. By changing the values of sequence identity and component overlap between assemblies required to define complex redundancy, we can create sets of representative complexes with known 3D structure (i.e., target complexes). Using an identity threshold of 20% and imposing a fraction of component overlap of <0.5, we identify 495 unique target complexes, which represent a real non-redundant set of heteromeric assemblies with known 3D structure. Moreover, for each target complex, we also identify a set of assemblies, of varying degrees of identity and component overlap, that can be readily used as input in a complex modeling exercise (i.e., template subcomplexes). We hope that resources like this will significantly help the development and progress assessment of novel methodologies, as docking benchmarks and blind prediction contests did.

AB - BACKGROUND/PURPOSE: Sternal fractures are rare in children. The purpose of this series is to document traumatic findings in pediatric patients with sternal fractures at a Level 1 trauma center. STUDY DESIGN: We reviewed the charts of patients with radiologically confirmed sternal fractures from a trauma database at a pediatric Level 1 trauma center between January 1, 2000 and December 31, 2015. We report mechanisms of injury, associated injuries, complications, and outcomes associated with sternal fractures. RESULTS: Over the 16-year period, 19/25,781 (0.07%) admitted patients had radiologically confirmed sternal fractures. 15/19 (78.9%) patients were male. The median age was 14 years, with interquartile range 10-16 years. 7/19, (36.8%) were sustained owing to motor vehicle accidents. Associated injuries included substernal hematoma (n = 6), pulmonary contusion (n = 4), vertebral injury (n = 2), rib fracture (n = 4), intraabdominal injury (n = 3), pneumothorax (n = 3), long bone injury (n = 3) traumatic brain injury (n = 2), hemothorax (n = 2), pneumomediastinum (n = 2) and cardiac contusion (n = 1). CONCLUSIONS: In this series, pediatric sternal fractures were caused by high velocity mechanisms and had significant comorbidity. While patients with isolated sternal fractures may be candidates for emergency department discharge, a thorough evaluation should be performed in children with sternal fractures to identify concurrent injuries.

AB - BACKGROUND: Wilms' tumor(WT) is the most common malignant renal tumor of childhood. Despite the good prognosis of WT, bilateral Wilms' tumor (BWT) still has a poor outcome. We systematically reviewed the literature on BWT, aiming to define its clinical features, treatment, and outcomes. METHODS: PubMed, OVID EMbase, Web of Science, and Cochrane Library were systematically searched for studies published from 1980 to 2017. Case series and comparative studies reported clinical data of BWT patients were included. RESULTS: A total of 32 studies comprising 1457 patients were retained for primary outcome. Hemihypertrophy, cryptorchidism, and Beckwith-Wiedemann syndrome(BWS) are the most common congenital anomalies and syndrome. 86% of patients had favorable histology (FH). Patients with local stage I or II accounted for 64%, and 12.6% had metastasis at diagnosis. Bilateral nephron-sparing surgery (NSS) was achieved in 33.8%. Recurrence and renal failure occurred in 20% and 8%. The overall survival (OS) was 73%. In comparative studies, OS of patients undergoing bilateral NSS was similar to that of other operation types. CONCLUSION: Prognosis of BWT has been improved but is significantly poorer than WT. Bilateral NSS was recommended by most centers to preserve more renal volume. However, finding a balance between retaining renal function and avoiding recurrence remains a question. TYPE OF STUDY: Systematic review. LEVEL OF EVIDENCE: Level IV. PMID- 30274709 TI - Transumbilical repair of umbilical hernia in children: The covert scar approach. AB - BACKGROUND: Umbilical hernia repairs are one of the most commonly performed operations in children. The traditional repair involves an infraumbilical incision, which produces a visible scar. We report a novel technique of umbilical hernia repair through a transumbilical incision, which eliminates the scar by hiding it within the umbilicus. METHODS: We performed a retrospective chart review of 134 patients who had undergone a transumbilical hernia repair at a single institution between 2008 and 2016. Satisfaction with cosmesis and the presence of complications were assessed through parental interviews during follow up visit or by telephone survey. These data were compared to a large volume retrospective analysis of the standard infraumbilical approach. RESULTS: 121 of the 134 patients were evaluated in the clinic or by telephone interview. The overall complication rate was 7.44%. Parents of 118 patients reported satisfaction with the cosmetic result (97.52%). In comparison to the largest study of pediatric infraumbilical repair, there was an improvement in subjective cosmesis without a significant increase in complications. CONCLUSION: Transumbilical hernia repair is a safe and cosmetically appealing technique for umbilical hernia repair in children. LEVEL OF EVIDENCE: Treatment study, level III. PMID- 30274710 TI - Vocal cord dysfunction following esophageal atresia and tracheoesophageal fistula (EA/TEF) repair. AB - BACKGROUND: The purpose of this study was to determine risk factors and long-term outcomes in patients with esophageal atresia +/-tracheoesophageal fistula (EA/TEF) with vocal cord dysfunction (VCD) owing to recurrent laryngeal nerve (RLN) injury. METHOD: A retrospective chart review was performed for EA/TEF patients repaired at our institution from 1999 to 2014 (REB #1000032265). RESULTS: Of 197 patients, 22 (11.2%) were diagnosed with VCD by indirect laryngoscopy following EA/TEF repair. Aspiration was documented on video swallow study for 21 patients, and as a result, 13 required thickened feeds and 8 required gastrostomy tube feeds. Of the 16 H-type TEF patients, 8 (50%) had VCD. Following discharge, 20 (90.9%) patients with VCD eventually tolerated full feeds orally without aspiration but only 8 (36.4%) had documented recovery of vocal cord movement at long-term follow up (mean 452 days). Overall, patients with VCD were more likely to have feeding modifications, increased exposure to radiological studies, and increased frequency of Otolaryngology follow-up compared to EA/TEF patients without VCD. CONCLUSION: EA/TEF patients are at risk for VCD. Clinical improvement did not always correlate with recovery of VC motion. Strategies to minimize RLN damage will improve outcomes and quality of life for EA/TEF patients. LEVEL OF EVIDENCE: Level III.

PMID- 30274713 TI - Sphingosine phosphate lyase insufficiency syndrome (SPLIS): A novel inborn error of sphingolipid metabolism. AB - Sphingosine-1-phosphate lyase (SPL) is an intracellular enzyme that controls the final step in the sphingolipid degradative pathway, the only biochemical pathway for removal of sphingolipids. Specifically, SPL catalyzes the cleavage of sphingosine 1-phosphate (S1P) at the C2-3 carbon bond, resulting in its irreversible degradation to phosphoethanolamine (PE) and hexadecenal. The substrate of the reaction, S1P, is a bioactive sphingolipid metabolite that signals through a family of five G protein-coupled S1P receptors (S1PRs) to mediate biological activities including cell migration, cell survival/death/proliferation and cell extrusion, thereby contributing to development, physiological functions and - when improperly regulated - the pathophysiology of disease. In 2017, several groups including ours reported a novel childhood syndrome that featured a wide range of presentations including fetal hydrops, steroid-resistant nephrotic syndrome (SRNS), primary adrenal insufficiency (PAI), rapid or insidious neurological deterioration, immunodeficiency, acanthosis and endocrine abnormalities. In all cases, the disease was attributed to recessive mutations in the human SPL gene, SGPL1. We now refer to this condition as SPL Insufficiency Syndrome, or SPLIS. Some features of this new sphingolipidosis were predicted by the reported phenotypes of Sgpl1 homozygous null mice that serve as vertebrate SPLIS disease models. However, other SPLIS features reveal previously unrecognized roles for SPL in human physiology. In this review, we briefly summarize the biochemistry, functions and regulation of SPL, the main clinical and biochemical features of SPLIS and what is known about the pathophysiology of this condition from murine and cell models. Lastly, we consider potential therapeutic strategies for the treatment of SPLIS patients. PMID- 30274714 TI - Endocannabinoid and nitric oxide systems of the hypothalamic paraventricular nucleus mediate effects of NPY on energy expenditure. AB - OBJECTIVE: Neuropeptide Y (NPY) is one of the most potent orexigenic peptides. The hypothalamic paraventricular nucleus (PVN) is a major locus where NPY exerts its effects on energy homeostasis. We investigated how NPY exerts its effect within the PVN. METHODS: Patch clamp electrophysiology and Ca2+ imaging were used to understand the involvement of Ca2+ signaling and retrograde transmitter systems in the mediation of NPY induced effects in the PVN. Immuno-electron microscopy were performed to elucidate the subcellular localization of the elements of nitric oxide (NO) system in the parvocellular PVN. In vivo metabolic profiling was performed to understand the role of the endocannabinoid and NO systems of the PVN in the mediation of NPY induced changes of energy homeostasis. RESULTS: We demonstrated that NPY inhibits synaptic inputs of parvocellular neurons in the PVN by activating endocannabinoid and NO retrograde transmitter systems via mobilization of Ca2+ from the endoplasmic reticulum, suggesting that NPY gates the synaptic inputs of parvocellular neurons in the PVN to prevent the influence of non-feeding-related inputs. While intraPVN administered NPY regulates food intake and locomotor activity via NO signaling, the endocannabinoid system of the PVN selectively mediates NPY-induced decrease in energy expenditure. CONCLUSION: Thus, within the PVN, NPY stimulates the release of endocannabinoids and NO via Ca2+-influx from the endoplasmic reticulum. Both transmitter systems appear to have unique roles in the mediation of the NPY induced regulation of energy homeostasis, suggesting that NPY regulates food intake, energy expenditure, and locomotor activity through different neuronal networks of this nucleus. PMID- 30274715 TI - Coral reef degradation affects the potential for reef recovery after disturbance. AB - The loss of coral cover is often accompanied by an increase of benthic algae, a decline in biodiversity and habitat complexity. However, it remains unclear how surrounding communities influence the trajectories of re-colonization between pulse disturbance events. Over a 12-month field experiment in the central Red Sea, we examined how healthy (hard-coral dominated) and degraded (algae dominated) reef areas influence recruitment and succession patterns of benthic reef foundation communities on bare substrates. Crustose coralline algae and other calcifiers were important colonizers in the healthy reef area, promoting the accumulation of inorganic carbon. Contrary, substrates in the degraded area were predominantly colonized by turf algae, lowering the accumulation of inorganic carbon by 178%. While coral larvae settlement similarly occurred in both habitats, degraded areas showed 50% fewer recruits. Our findings suggest that in degraded reefs the replenishment of adult coral populations is reduced due to recruitment inhibition through limited habitat complexity and grazing pressure, thereby restraining reef recovery. PMID- 30274716 TI - Environmental conditions affect activity and associated microorganisms of marine sponges. AB - Changes in environmental conditions can influence sponges and their holobionts. The present study investigated the effect of upwelling and anthropogenic pollution on the bioactivity of marine sponges, microbial communities and functional genes, and composition of their chemical compounds. The species Dysidea etheria, Darwinella sp., Hymeniacidon heliophila and Tedania ignis were collected from areas with distinct influence of upwelling and low anthropogenic impact and from areas without influence of upwelling but affected by sewage and the port. In most cases, the same sponge species collected from areas with distinct environmental conditions had a different chemical composition, antifouling activity, composition and diversity of associated microorganisms. Antimicrobial, quorum sensing inhibitory and anti-larval activities of sponge extracts were more pronounced in the area without upwelling showing higher level of anthropogenic pollution. This study suggests that upwelling and anthropogenic pollution affect the chemical activity and holobiome composition of sponges. PMID- 30274717 TI - Quantitative analysis of fish and invertebrate assemblage dynamics in association with a North Sea oil and gas installation complex. AB - Decommissioning of offshore infrastructure has become a major issue facing the global offshore energy industry. In the North Sea alone, the decommissioning liability is estimated at L40 billion by 2040. Current international policy requires removal of offshore infrastructure when their production life ends; however, this policy is being questioned as emerging data reveal the importance of these structures to fish and invertebrate populations. Indeed, some governments are developing 'rigs-to-reef' (RTR) policies in situations where offshore infrastructure is demonstrated to have important environmental benefits. Using Remotely Operated Vehicles (ROVs), this study quantified and analysed fish and invertebrate assemblage dynamics associated with an oil and gas (O&G) complex in the Dogger Bank Special Area of Conservation (SAC), in the North Sea, Germany. We found clear depth zonation of organisms: infralittoral communities (0-15 m), circalittoral assemblages (15-45 m) and epi-benthic communities (45-50 m), which implies that 'topping' or 'toppling' decommissioning strategies could eliminate communities that are unique to the upper zones. Sessile invertebrate assemblages were significantly different between structures, which appeared to be driven by both biotic and abiotic mechanisms. The O&G complex accommodated diverse and abundant motile invertebrate and fish assemblages within which the whelk Buccinium undatum, cod fish Gadus morhua and lumpsucker fish Cyclopterus lumpus used the infrastructure for different stages of reproduction. This observation of breeding implies that the structures may be producing more fish and invertebrates, as opposed to simply acting as sites of attraction (sensu the 'attraction vs production' debate). At present, there are no records of C. lumpus spawning at such depth and distance from the coast, and this is the first published evidence of this species using an offshore structure as a spawning site. Overall, this study provides important new insight into the role of offshore O&G structures as habitat for fish and invertebrates in the North Sea, thereby helping to inform decommissioning decisions. PMID- 30274718 TI - Current practices and knowledge supporting oil spill risk assessment in the Arctic. AB - Oil spill response (OSR) in the Arctic marine environment conducted as part of operational planning and preparedness supporting exploration and development is most successful when knowledge of the ecosystem is readily available and applicable in an oil spill risk assessment framework. OSR strategies supporting decision-making during the critical period after a spill event should be explicit about the environmental resources potentially at risk and the efficacy of OSR countermeasures that best protect sensitive and valued resources. At present, there are 6 prominent methods for spill impact mitigation assessment (SIMA) in the Arctic aimed at supporting OSR and operational planning and preparedness; each method examines spill scenarios and identifies response strategies best suited to overcome the unique challenges posed by polar ecosystems and to minimize potential long-term environmental consequences. The different methods are grounded in classical environmental risk assessment and the net environmental benefit analysis (NEBA) approach that emerged in the 1990s after the Exxon Valdez oil spill. The different approaches share 5 primary assessment elements (oil physical and chemical properties, fate and transport, exposure, effects and consequence analysis). This paper highlights how the different Arctic methods reflect this common risk assessment framework and share a common need for oil spill science relevant to Arctic ecosystems. An online literature navigation portal, developed as part of the 5-year Arctic Oil Spill Response Technologies Joint Industry Programme, complements the different approaches currently used in the Arctic by capturing the rapidly expanding body of scientific knowledge useful to evaluating exposure, vulnerability and recovery of the Arctic ecosystem after an oil spill.

AB - Fouling release coatings (FRCs) are today the main environment-friendly alternative to traditional self-polishing coatings, that continuously release biocides and/or heavy metals into water. FRCs are available on the market as environmentally friendly AF paints and most of them do not contain bioactive agents, however no complete and reliable assessment of their environmental impact has yet been carried out. Only few literature data proving their AF efficacy combined with a demonstrated lack of toxicological effects are available. Ecotoxicological bioassays are commonly used to predict the potential environmental impact of traditional AF paints. Standardized methodologies to obtain leaching products from biocide-based paints are available, while few studies propose experimental methods to assess the potential effects of biocide free FRCs leachates on non-target organisms. The aim of this work is to propose an experimental protocol to obtain leaching products from biocide-free FRCs in order to evaluate the potential release of substances having toxic effects, by means of an ecotoxicological bioassay. Two ecotoxicological end-points with different sensitivity levels were considered (multi-end-point approach). Five silicone-based commercial coatings were used: their leaching products were collected after different immersion times following the developed experimental method and then two ecotoxicological end-points were evaluated on II stage nauplii of the crustacean Amphibalanus amphitrite as model organism. Moreover, chemical analyses were performed on leachates collected after each immersion time, focusing on the presence of metals in leaching products. From the results obtained from the bioassay, even if not indicative of the real environmental impact of FRCs, a release of toxic substances was observed from tested coatings during early immersion stages, likely to affect the exposed model organism. The potential leaching toxicity of the five tested products was compared. No clear correspondence could be identified between the concentrations of metals detected in leachates and the obtained ecotoxicological data, thus suggesting that other active components might be released by FRCs responsible for the toxic effects pointed out on A. amphitrite larvae.

AB - The aim of this study was to detect ecotoxicological effects of 0.1 MUm polystyrene microbeads in marine organisms belonging to different trophic levels. MP build up, lethal and sub-lethal responses were investigated in the bacterium Vibrio anguillarum (culturability), in the green microalga Dunaliella tertiolecta (growth inhibition), in the rotifer Brachionus plicatilis (mortality and swimming speed alteration) and in the sea urchin Paracentrotus lividus (immobility and swimming speed alteration) exposed to a wide range of microplastic (MP) concentrations (from 0.001 to 10 mg L-1). Survival was not affected in all organisms up to 10 mg L-1, while algal growth inhibition, rotifer and sea urchin larvae swimming behaviour alterations were observed after exposure to MPs. Ingestion was only observed in rotifers and it was directly correlated with sub lethal effects. These results account for the ecotoxicological risk associated to the polystyrene microbeads, which are able to affect different endpoints in primary producers and consumers (rotifers and sea urchins) since no effects were observed in decomposers. This study points out the importance of using a battery of marine organisms belonging to different trophic levels by studying acute toxicity of MPs at low and high contamination levels, and investigating sub lethal responses. Further investigations aimed at studying the transfer of these materials through the web are particularly recommended.

PMID- 30274721 TI - Quality of life changes after stereotactic ablative radiotherapy for liver metastases: A prospective cohort analysis. AB - PURPOSE: To report the changes in quality of life (QoL) after stereotactic ablative radiotherapy (SABR) in patients with liver metastases (LM). MATERIALS AND METHODS: A prospective cohort study was undertaken to measure the acute changes in QoL after SABR. Patients with 1-3 treated LM were eligible. Doses of 30-60 Gy in 3-5 fractions were delivered. Prospective QoL was measured using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaires, Core 15 for Palliative Care (EORTC QLQ-C15-PAL) and liver metastases (LM21), at baseline, 1st week and last day of treatment, then 1, 6 and 12 weeks after SABR. The functional living index-emesis (FLIE) was collected at baseline, 1st week, last day and 1 week after treatment. Univariable and multivariable linear mixed modeling were performed as appropriate to assess changes in QoL over time. RESULTS: Sixty patients were included. The most common primary cancer was colorectal (42%). The global health score measured by QLQ-C15 PAL was significantly worse at treatment completion (p = 0.001), 1 week (p = 0.003) and 6 weeks (p = 0.002) after SABR but recovered by 12 weeks (p = 0.124). Nausea and constipation were worse at treatment completion (p < 0.05) but recovered 1 week after while fatigue recovered 6 weeks post-SABR. The majority of patients reported stable QoL at 12 weeks for all domains in the C15-PAL and LM21 questionnaires. CONCLUSION: SABR offers a non-invasive mean of ablating LM with minimal impact on acute QoL. PMID- 30274723 TI - Effects of the Australian National Hand Hygiene Initiative after 8 years on infection control practices, health-care worker education, and clinical outcomes: a longitudinal study. AB - BACKGROUND: The National Hand Hygiene Initiative (NHHI) is a standardised culture change programme based on the WHO My 5 Moments for Hand Hygiene approach to improve hand hygiene compliance among Australian health-care workers and reduce the risk of health-care-associated infections. We analysed its effectiveness. METHODS: In this longitudinal study, we assessed outcomes of the NHHI for the 8 years after implementation (between Jan 1, 2009, and June 30, 2017), including hospital participation, hand hygiene compliance (measured as the proportion of observed Moments) three times per year, educational engagement, cost, and association with the incidence of health-care-associated Staphylococcus aureus bacteraemia (HA-SAB). FINDINGS: Between 2009 and 2017, increases were observed in national health-care facility participation (105 hospitals [103 public and two private] in 2009 vs 937 hospitals [598 public and 339 private] in 2017) and overall hand hygiene compliance (36 213 [63.6%] of 56 978 Moments [95% CI 63.2 63.9] in 2009 vs 494 673 [84.3%] of 586 559 Moments [84.2-84.4] in 2017; p<0.0001). Compliance also increased for each Moment type and for each health care worker occupational group, including for medical staff (4377 [50.5%] of 8669 Moments [95% CI 49.4-51.5] in 2009 vs 53 620 [71.7%] of 74 788 Moments [71.4 72.0]; p<0.0001). 1 989 713 NHHI online learning credential programmes were completed. The 2016 NHHI budget was equivalent to AUD$0.06 per inpatient admission nationally. Among Australia's major public hospitals (n=132), improved hand hygiene compliance was associated with declines in the incidence of HA-SAB (incidence rate ratio 0.85; 95% CI 0.79-0.93; p<=0.0001): for every 10% increase in hand hygiene compliance, the incidence of HA-SAB decreased by 15%. INTERPRETATION: The NHHI has been associated with significant sustained improvement in hand hygiene compliance and a decline in the incidence of HA-SAB. Key features include sustained central coordination of a standardised approach and incorporation into hospital accreditation standards. The NHHI could be emulated in other national culture-change programmes. FUNDING: Australian Commission on Safety and Quality in Health Care.

PMID- 30274725 TI - A novel preoperative model to predict 90-day surgical mortality in patients considered for renal cell carcinoma surgery. AB - INTRODUCTION: Surgical benefits for renal cell carcinoma must be weighed against competing causes of mortality, especially in the elderly patient population. We used a large cancer registry to evaluate the impact of patient and cancer specific factors on 90-day mortality (90DM). A nomogram to predict the odds of short-term mortality was created. MATERIALS AND METHODS: The National Cancer Database was queried to identify all patients with clinically localized, nonmetastatic disease treated with partial or radical nephrectomy. Using a random sample of 60%, multiple logistic regression with 90DM outcomes were performed to identify preoperative variables associated with mortality. Variables included age, sex, race, co-morbidity score, tumor size, and presence of a thrombus. A nomogram was created and tested on the remaining 40% of patients to predict 90DM. RESULTS: 183,407 patients met inclusion criteria. Overall 90DM for the cohort was 1.9%. All preoperative variables significantly influenced the risk of 90DM. Patient age was by far the strongest predictor. Nomogram scores ranged from 0 to 12. Compared to patients with 0 to 1 points, those with 2 to 3 (odds ratio [OR] 2.89, 2.42-3.46; P < 0.001), 4 to 5 (OR 6.25, 5.26-7.43; P < 0.001), and >6 (OR 12.86, 10.83-15.27; P < 0.001) were at incrementally significantly higher odds of 90DM. Being >80 years of age alone placed patients into the highest risk of surgical mortality. CONCLUSIONS: Management of localized kidney cancer must consider competing causes of mortality, especially in elderly patients with multiple co-morbidities. We present a preoperative tool to calculate risk of surgical short-term mortality to aid surgeon-patient counseling.

PMID- 30274727 TI - Process Evaluation of a Policy, Systems, and Environmental Change Intervention in an Urban School District. AB - OBJECTIVE: To conduct a comprehensive process evaluation of a policy, systems, and environmental (PSE) change intervention. DESIGN: Quasi-experimental, mixed methods. SETTING: Low-income urban school district. PARTICIPANTS: Fifth-grade students in 4 schools assigned to 2 intervention and 2 comparison schools (intervention, n = 142; comparison, n = 170). INTERVENTION: Both groups received a nutrition curriculum delivered by classroom teachers. Intervention schools also received 10 PSE lessons taught by paraprofessional educators. MAIN OUTCOME MEASURES: Quantitative data were obtained from fidelity and observation checklists, grading rubrics and self-reported student surveys. Focus group and interviews provided qualitative data. Quantitative measures included assessments of PSE and fruit and vegetable knowledge, as well as assessment of times fruits and vegetables (FV) were consumed yesterday. ANALYSES: Qualitative data were analyzed using inductive content analysis. Quantitative data were analyzed using repeated measures analysis of variance and analysis of co-variance. RESULTS: Fidelity, dose, reach, and acceptance of PSE intervention were high; students felt more empowered, although PSE lessons were considered lengthy and complicated. Intervention PSE and FV knowledge scores were significantly higher than comparison scores (F37.56, P < .001; and F3.94, P < .05, respectively). However, issues in communication were identified between school staff and researchers. CONCLUSIONS AND IMPLICATIONS: Policy, systems, and environmental classroom interventions commented on the differences between quantitative and qualitative assessments, and this suggests the need for more sensitive quantitative assessments. Future research should look at long-term outcomes as this study only looked at short-term outcomes. PMID- 30274728 TI - Pyomyositis Diagnosed by Point-of-Care Ultrasound in the Emergency Department. AB - BACKGROUND: Currently, the role of ultrasound in diagnosing superficial abscesses is well validated, however, its role for deep space infections and intramuscular pathology is limited. Distinguishing between simple cellulitis and abscess is critical for emergency physicians (EP), as the treatment is very different. Management of cellulitis relies on antibiotic therapy, whereas abscess treatment requires incision and drainage. It is important that EPs can accurately distinguish between the two entities. CASE REPORT: We report a case of a 41-year old man with a history of high blood pressure and poorly controlled diabetes who presented with right lateral thigh redness, warmth, and tenderness. A point-of care ultrasound (POCUS) of the patient's right lateral thigh with a high frequency linear (8 MHz) ultrasound probe showed a 2.93 * 3.38 * 6.0-cm complex fluid collection deep to the fascial plane, approximately 3.0 cm from the skin surface, that contained mixed echogenicities with posterior acoustic enhancement consistent with an intramuscular abscess of the vastus lateralis. The patient was diagnosed with pyomyositis of his vastus lateralis. He was started on vancomycin and admitted to the surgical service for antibiotic treatment and surgical drainage. WHY SHOULD EMERGENCY PHYSICIANS BE AWARE OF THIS?: This case demonstrates that the use of POCUS by EPs can facilitate the rapid recognition and treatment of a disease that is challenging to diagnose on physical examination and can be potentially life-threatening if missed. EPs can consider performing a POCUS when evaluating skin infections to ensure rapid diagnosis and appropriate medical care for a potentially severe condition. PMID- 30274729 TI - A Uniquely Abnormal Stool Specimen: A Case Report. AB - BACKGROUND: Autoamputation of the appendix is a condition associated with the Ladd's procedure, a pediatric surgical technique for correction of intestinal malrotation. A 4-year-old male patient with a history of a Ladd's procedure performed as a newborn was brought in by his mother for "passing intestine" just prior to arrival. She reported that for several weeks her son had intermittent, crampy abdominal pain that resolved after the unusual-appearing bowel movement. After reviewing an image of the bowel movement, and in consultation with pediatric surgery, it was concluded that the patient had passed a devascularized appendix in his stool immediately prior to arrival. CASE REPORT: A 4-year-old boy with a past medical history of heterotaxy syndrome (inversion of the thoraco abdominal organs), a double outlet right ventricle, and Ladd's procedure presented to the Emergency Department (ED) after "passing intestine" in his stool. Close examination of the photo demonstrated a tubular structure with taenia, consistent with an appendix. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Autoamputation of the appendix is an uncommon presentation in the ED. Passing a devascularized appendix is a benign condition and can present with weeks of intermittent abdominal pain that resolves with passage of appendix in the stool. Remnants of the appendix can remain within the intestinal lumen years after the Ladd's procedure. Emergency physicians with a general awareness of this rare phenomenon can confidently make the diagnosis and reassure worried parents. PMID- 30274730 TI - Febrile Infant with Skin Rash. PMID- 30274731 TI - The World Bank Group: Innovative financing for health and opportunities for global surgery. AB - The World Bank Group is the largest global development organization working to end poverty and promote shared prosperity. Its 5 institutions play an essential role in the advancement of global health through innovative health financing, data collection and management, policy reform, and advocacy. Previously, the World Bank Group has supported global surgery through data collection and advocacy. As it grows, it must continue to focus on the importance of surgical care in promoting health and avoiding poverty in low- and middle-income countries. The house of surgery and its community should play an active role in advocating for the many ways in which the World Bank Group could facilitate the strengthening of surgical systems to improve access to surgical care worldwide. PMID- 30274732 TI - High-dose radioactive iodine therapy is associated with decreased risk of recurrence in high-risk papillary thyroid cancer. AB - OBJECTIVES: We aimed to determine the effect of adjuvant radioactive iodine dose on recurrence rate in high-risk papillary thyroid cancer. METHODS: More than 1,500 patients treated for papillary thyroid cancer at high-volume centers in France and the United States from 2004-2014 were reviewed. Patients considered at high risk for recurrence per the 2015 American Thyroid Association guidelines were analyzed and grouped by initial radioactive iodine dose: intermediate (median 100 mCi) or high dose (median 150 mCi). Propensity score matching was performed to control for baseline characteristics. RESULTS: In a propensity matched cohort of 66 patient pairs, there were equivalent rates of gross extrathyroidal extension (71% vs 71%, P = 1.00), positive margins (55% vs 55%, P = 1.00), lymph node metastases >= 3 cm (9% vs 9%, P = 1.00), extranodal extension (32% vs 33%, P = .85), and distant metastases (2% vs 5%, P = .31). Over a median follow-up of 4.5 years (interquartile ratio 2.0-7.5 years), the intermediate-dose radioactive iodine group had a significantly higher rate of recurrence than patients in the high-dose radioactive iodine group: 24 out of 66 (36%) vs 13 out of 66 (20%), P = .03. CONCLUSION: High-dose radioactive iodine is associated with lower recurrence rate compared with intermediate-dose radioactive iodine for patients with American Thyroid Association high-risk papillary thyroid cancer. PMID- 30274733 TI - Heterogeneous and low-intensity parathyroid autofluorescence: Patterns suggesting hyperfunction at parathyroid exploration. AB - BACKGROUND: Although parathyroid glands have been found to exhibit autofluorescence with near-infrared fluorescence imaging, it is unknown if autofluorescence characteristics vary between hyperfunctioning and normofunctioning glands. The hypothesis was that pattern of autofluorescence exhibited by hyperfunctioning versus normofunctioning parathyroid glands would be different. METHODS: This is an Institutional Review Board-approved, prospective clinical study. Patients underwent bilateral neck exploration for primary hyperparathyroidism, during which autofluorescence from each gland was assessed with near-infrared fluorescence imaging. Pattern and intensity of autofluorescence between hyperfunctioning and normofunctioning parathyroid glands were compared. RESULTS: Overall, 199 parathyroid glands were identified in 50 patients (single gland disease, n = 31; multigland disease, n = 19). Autofluorescence was detected from 96% (n = 192) of parathyroid glands, all of which exhibited a higher intensity autofluorescence than the background tissues. Parathyroid gland location was revealed by near-infrared fluorescence imaging before dissection in 26% (n = 52). A total of 77 glands that were large or firm were excised and 122 were preserved because of normal appearance. Hyperfunctioning parathyroid glands had a lower mean normalized autofluorescence intensity than normofunctioning parathyroid glands (1.8, and 2.6, respectively, P < .001). Moreover, hyperfunctioning parathyroid glands more often exhibited a heterogeneous pattern of autofluorescence (75% and 5%, respectively, P < .001). On multivariate analysis, only parathyroid gland hyperfunction correlated with normalized autofluorescence intensity. On receiver operative characteristic curve, optimal cutoff of normalized autofluorescence intensity to differentiate hyperfunctioning from normofunctioning parathyroid glands was 2.0. CONCLUSION: Our results indicate that hyperfunctioning and normofunctioning parathyroid glands exhibit different patterns of autofluorescence in hyperparathyroidism. Given these findings, autofluorescence pattern could be implemented as another adjunctive parameter for gland assessment during parathyroid exploration. PMID- 30274734 TI - Delayed bone healing by collagen membrane in early phase of 4 weeks. AB - OBJECTIVE: Barrier membranes are important in maintaining space in guided bone regeneration process by preventing downgrowth of epithelial or connective tissue. In this study, the effects of resorbable membranes during the early stages of bone regeneration in rats with impaired bone healing capacity were investigated. STUDY DESIGN: Twenty-eight rats were selected for this study. Half of the animals were selected for radiation therapy before surgical procedure (G3, G4). Animals were assigned into 4 groups (G1-G4). A circular defect was created in the central parietal bone. It was covered with resorbable membrane in G2 and G4. After 4 weeks, the animals were sacrificed. RESULTS: At week 4, the new bone formation was observed around the margin of old bone in G1, G2 and G4 groups. Osteoclast was most abundant in the G1 group (18.3 +/- 7.7) and least abundant in the G4 group (7.9 +/- 4.7). The mean of osteocalcin levels in blood was the highest in the G2 group and lowest in the G3 group. Only G4 group showed significant difference in Runx2 levels between before-treatment and after- treatment. CONCLUSIONS: Bone healing is adversely affected after radiation therapy. In addition, resorbable membranes can delay healing in the early stages of bone regeneration. PMID- 30274735 TI - How to Manage Heart Failure: New Guidelines 2018.

PMID- 30274737 TI - Personalized stent design for congenital heart defects using pulsatile blood flow simulations. AB - Stent size selection and placement are among the most challenging tasks in the treatment of pulmonary artery stenosis in congenital heart defects (CHD). Patient specific 3D model from CT or MR improves the understanding of the patient's anatomy and information about the hemodynamics aid in patient risk assessment and treatment planning. This work presents a new approach for personalized stent design in pulmonary artery interventions combining personalized patient geometry and hemodynamic simulations. First, the stent position is initialized using a geometric approach. Second, the stent and artery expansion, including the foreshortening behavior of the stent is simulated. Two stent designs are considered, a regular stent and a Y-stent for bifurcations. Computational fluid dynamics (CFD) simulations of the blood flow in the initial and expanded artery models are performed using patient-specific boundary conditions in form of a pulsatile inflow waveform, 3-element Windkessel outflow conditions, and deformable vessel walls. The simulations have been applied to 16 patient cases with a large variability of anatomies. Finally, the simulations have been clinically validated using retrospective imaging from angiography and pressure measurements. The simulated pressure, volume flow and flow velocity values were on the same order of magnitude as the reference values obtained from clinical measurements, and the simulated stent placement showed a positive impact on the hemodynamic values. Simulation of geometric changes combined with CFD simulations offers the possibility to optimize stent type, size, and position by evaluating different configurations before the intervention, and eventually allow to test customized stent geometries and new deployment techniques in CHD. PMID- 30274738 TI - Burden of cytomegalovirus disease in allogeneic hematopoietic cell transplant recipients: a national, matched cohort study in an inpatient setting. AB - PURPOSE OF THE STUDY: No studies have compared the risk of mortality or graft versus-host disease, in an inpatient setting in France, in allogeneic hematopoietic cell transplant recipients who develop cytomegalovirus disease with those who do not. This study assessed the impact of cytomegalovirus disease on clinical outcomes and healthcare resource utilization in allogeneic hematopoietic cell transplant recipients using the French Programme de Medicalisation des Systemes d'Information database. PATIENTS AND METHODS: Recipients who had undergone allogeneic hematopoietic cell transplant in French hospitals between 2008 and 2011 were included in this retrospective, matched cohort study. Those with cytomegalovirus disease were each matched with two allogeneic hematopoietic cell transplant recipients without cytomegalovirus disease according to demographic and clinical characteristics. Probabilities of in-hospital mortality, graft rejection and/or graft-versus-host disease, and healthcare resource utilization were compared up to 12 months after cytomegalovirus disease diagnosis. RESULTS: Overall, 4884 transplant recipients were enrolled, of which 194 had cytomegalovirus disease. Of these, 165 recipients with cytomegalovirus disease were matched to 330 without cytomegalovirus disease (1:2 ratio). The development of cytomegalovirus disease was associated with a significantly higher risk of in-hospital mortality (relative risk = 1.7, p = 0.0005) and higher cumulative number of inpatient days (p < 0.0001), but was not associated with a significantly higher risk of graft rejection and/or graft-versus-host disease or healthcare costs. CONCLUSIONS: Due to the increased risk of in-hospital mortality and higher cumulative number of inpatient days in allogeneic hematopoietic cell transplant recipients with cytomegalovirus disease versus those without, new strategies to prevent and manage cytomegalovirus disease are warranted. PMID- 30274739 TI - Content and accuracy of nutrition-related posts in bariatric surgery Facebook support groups. AB - BACKGROUND: Support after bariatric surgery is critical. Access to bariatric support groups is sometimes challenging, leading people to seek support on social media platforms like Facebook. Given the ubiquity of recommendations solicited and provided on Facebook regarding nutrition and bariatric surgery, understanding the content and accuracy of these posts is important. OBJECTIVES: The primary aim of the present study was to describe the content of nutrition-related information sought on bariatric Facebook support groups/pages. A secondary aim was to evaluate the accuracy of this content. SETTING: Integrated multispecialty health system. METHODS: An iterative content analysis process was conducted and resulted in identification of 8 primary coding themes. Additionally, 3 registered dieticians with extensive experience in bariatric surgery and obesity treatment examined posts that provided nutritional recommendations to determine accuracy. RESULTS: Members most commonly sought advice regarding products and practices to assist in achieving nutritional guidelines (35%). Over half of the posts contained inaccurate content or information that was too ambiguous to determine accuracy; 7% of posts were found to be inaccurate or inconsistent with American Society for Metabolic and Bariatric Surgery nutrition guidelines and expert registered dietician opinions, 22% of posts were found to contain both accurate and inaccurate information, and 24% of posts were considered too ambiguous and required more context to determine the accuracy. CONCLUSIONS: Results highlight the need for bariatric programs to provide greater nutrition education support to patients postoperatively and to provide caution about the inconsistent nature of some nutrition-related content found on Facebook bariatric support groups. PMID- 30274740 TI - Postoperative outcomes based on patient participation in a presurgery education and weight management program. AB - BACKGROUND: The benefits of presurgery weight management programs (WMPs) for bariatric patients are mixed; some show a positive impact on percent excess weight loss (%EWL) at 12 months postsurgery, while others show no effect. OBJECTIVES: The purpose of this study was to compare pre- and postoperative 6- and 12-month outcomes between patients who attended a 12-week presurgery WMP and patients who did not participate. SETTING: Ohio State Wexner Medical Center, University Hospital, United States. METHODS: A retrospective medical record analysis was conducted to compare preoperative and 6- and 12-month postoperative outcomes for patients who attend the presurgery WMP (n = 56) and patients who did not (n = 441) within a 2-year time period (N = 497). Descriptive statistics and independent t tests were conducted to determine mean differences between groups, while controlling for surgery type, for weight status outcomes (%EWL, change in body mass index) preoperatively and 6 and 12 months postsurgery, and length of stay and readmission rate. RESULTS: Patients who attended the preoperative WMP had significantly higher %EWL at 12 months postsurgery compared with patients who did not attend the WMP. Additional findings indicated a positive, but nonsignificant effect, from the WMP on presurgery body mass index, and postsurgery %EWL at 6 months and body mass index change at 6 and 12 months postsurgery. CONCLUSIONS: Patients attending the WMP had better 12-month %EWL and outcomes compared with those who did not attend the WMP, though this was not true for 6-month outcomes and differed based on surgery type. PMID- 30274741 TI - Cocaine and amphetamine regulated transcript and brain-derived neurotrophic factor in morbid obesity. One-year follow-up after gastric bypass. AB - BACKGROUND: The identification of biomarkers associated with obesity and response to treatment could represent an important advance to design more effective and personalized therapeutic strategies. The complexity of morbid obesity could be explained as the combination of genetic, biochemical, cultural, and behavioral factors, among others. The study of biomarkers should be considered a determinant factor taken into account in this equation. OBJECTIVES: The aim of this study was to define better biomarker profiles potentially associated to the short-term outcome of bariatric surgery by paying attention to cocaine and amphetamine regulated transcript and brain-derived neurotrophic factor, 2 neuropeptides related to eating behavior. SETTING: University General Hospital of Ciudad Real, Spain. METHODS: Twenty-seven morbidly obese patients and 30 healthy weight individuals matched by age and sex were selected for the study. RESULTS: Patients underwent bariatric surgery by Roux-en-Y gastric bypass and responded adequately in terms of weight loss and normalization of many biochemical parameters 1 year postsurgery. A multivariate analysis showed that the hormonal/neuropeptidic profile explained 82% of the variability of the weight loss response. The evolution of cocaine and amphetamine regulated transcript paralleled that of insulin and leptin, serum levels of this peptide were initially elevated in patients (4.24 +/- .47 ng/mL) with respect to controls (2.94 +/- .2 ng/mL), but this difference disappeared 1 year after Roux-en-Y gastric bypass (3.14 +/- .26 ng/mL). Brain-derived neurotrophic factor levels were also decreased by Roux-en-Y gastric bypass (11.93 +/- .96 ng/mL postsurgery versus 15.3 +/- 1.02 ng/mL presurgery), even when this peptide was not elevated in patients before surgery (14.23 +/- .86 ng/mL in controls). CONCLUSIONS: The results suggest that cocaine and amphetamine regulated transcript and brain-derived neurotrophic factor could be envisaged as new candidate biomarkers of short-term outcome after surgery. PMID- 30274742 TI - Proteomic profile of sex-sorted bull sperm evaluated by SWATH-MS analysis. AB - The identification of distinct proteins present on the membrane of spermatozoa with X and Y chromosomes allows the development of immuno-sexing techniques. The aim of this study, therefore, was to use mass spectrometry to analyze the protein profile of sperm previously categorized using flow cytometry into X or Y-bearing semen pools. Sex-sorted sperm samples (n = 6 X and n = 6 Y) were used. Proteins were extracted and analyzed by mass spectrometry using data independent acquisition (DIA). The data were searched against taxonomy Bos taurus in the Swiss Prot database. In total, 459 protein groups were identified. Of these, eight proteins were in differential abundances between the X- and Y-bearing sperm population. Among the major proteinsdetected, EF-hand domain-containing protein 1, a protein involved in embryonic development, is more abundant in Y-bearing spermatozoa. In addition, proteins FUN14, domain-containing protein 2, NADH dehydrogenase [ubiquinone] iron-sulfur protein 7 mitochondrial, cytochrome C oxidase subunit 2, acetyl -CoA carboxylase type beta were more abundant in X bearing sperm. In conclusion, there were differences in abundance of proteins between X- and Y-bearing bull spermatozoa. This fact, may contribute to future studies related to sperm physiology and possibility development of immuno-sexing techniques. PMID- 30274743 TI - Theoretical studies of the pyranose ring under mechanical stress. AB - In this work we use our Enforced Geometry Optimization (EGO) method to investigate conformational transitions in the pyranose ring under mechanical stress caused by external forces. We examine possible transitions and/or inversions induced by external forces in the pyranose ring in the chair conformation with two axial glycosidic bonds. The results obtained provide new insight into the mechanism of the conformational transitions which strongly depends on substituents present in a pyranose ring. We also conclude that interpretation of AFM force-extension curves is not necessarily straightforward; not every plateau there corresponds to a conformational transition and not every transition can be clearly seen as a plateau. PMID- 30274744 TI - Determining the likelihood that fatigue was present in a road accident: A theoretical review and suggested accident taxonomy. AB - Estimates in developed countries of the extent to which fatigue contributes to road accidents range from as low as 5% to as high as 50% of all accidents. Compared with other causes of road accidents (e.g., speeding, drink-driving), the variability in these estimates is exceptionally high and may be indicative of the difficulty in determining the likelihood of fatigue as a cause of road accidents. This review compares differences in the way road accidents are classified as fatigue-related (or not) by expert panels and road safety regulators, highlighting conflicting conceptual approaches, lack of consistency, and the poor psychometric qualities of classification rules used across jurisdictions. In order to facilitate future research, the review then proposes a new theoretical approach and a potentially more logical accident 'taxonomy'. A putative accident 'taxonomy' is proposed using two dimensions: (1) estimating the likelihood that a driver was fatigued at the time of the accident, and (2) estimating the degree to which accident phenomenology is consistent with fatigue-related error. This 'taxonomy' could assist accident investigators and road safety regulators to more reliably quantify the contribution of fatigue to road accidents, and may also assist researchers and regulators in the post-hoc interrogation of existing accident databases to better determine the relative incidence of fatigue-related road accidents.

AB - Participation is a process that requires the involvement of the policy makers, managers, technicians and staff of the institutions, and of citizens, as well as intersectoral and interdisciplinary action. To generate transformative changes, an infrastructure that encourages participation and planned action is required, and that recognises all the actors in the process. It takes time and commitment to ensure continuity through the joint production of actions, hence the importance of consolidating participatory projects that continue beyond political changes making public services sustainable. Training, the appropriate use of participation tools and a horizontal policy of delegated power are essential to ensure participation. Surveys, sociograms, flowcharts, health assets mapping, participatory budgets and participatory evaluation matrices are some of the tools that can be chosen, depending on the type of subjects addressed, the time and resources available, the characteristics of the participating population and territory, as well as determining the use that will be made of the information generated for the next phase. Participation tools are useful for citizens and professionals to analyze, understand, debate and decide collectively how to improve living conditions and environments. Over the past decade, social networks in the virtual environment have generated new trends in mass participation, which are self-managed by citizens. PMID- 30274748 TI - Finding the right balance.

PMID- 30274750 TI - Incremental diagnostic and prognostic value of the QRS-T angle, a 12-lead ECG marker quantifying heterogeneity of depolarization and repolarization, in patients with suspected non-ST-elevation myocardial infarction. AB - BACKGROUND: The value of the 12-lead ECG in the diagnosis of non-ST-elevation myocardial infarction (NSTEMI) is limited due to insufficient sensitivity and specificity of standard ECG criteria. The QRS-T angle reflects depolarization repolarization heterogeneity and might assist in detecting patients with a NSTEMI (diagnosis) as well as predicting patients with an increased mortality risk (prognosis). METHODS: We prospectively enrolled 2705 consecutive patients with symptoms suggestive of NSTEMI. The QRS-T angle was automatically derived from the standard 10 s 12-lead ECG recorded at presentation to the ED. Patients were followed up for all-cause mortality for 2 years. RESULTS: NSTEMI was the final diagnosis in 15% (n = 412) of patients. QRS-T angles were significantly greater in patients with NSTEMI compared to those without (p < 0.001). The use of the QRS T angle in addition to standard ECG criteria indicative of ischemia improved the diagnostic accuracy for NSTEMI as quantified by the area under the ROC curve from 0.68 to 0.72 (p < 0.001). An algorithm for the combined use of standard ECG criteria and the QRS-T angle improved the sensitivity of the ECG for NSTEMI from 45% to 78% and the specificity from 86% to 91% (p < 0.001 for both comparisons). The 2-year survival rates were 98%, 97% and 87% according to QRS-T angle tertiles (p < 0.001). CONCLUSION: In patients with suspected NSTEMI, the QRS-T angle derived from the standard 12-lead ECG provides incremental diagnostic accuracy on top of standard ECG criteria indicative of ischemia, and independently predicts all-cause mortality during 2 years of follow-up.

AB - BACKGROUND: Severe mitral regurgitation (MR) on hospital arrival at the onset of acute decompensated heart failure (ADHF) can improve after ADHF treatment because MR is dynamic in nature. This study investigated the clinical significance of the dynamic severe MR on hospital arrival in ADHF patients. METHODS: Transthoracic echocardiography was performed on 784 patients hospitalized for ADHF both on arrival and after ADHF treatment, of whom 563 with at least mild MR after ADHF treatment were enrolled and divided into 3 groups based on the MR severity: severe at both times (persistent MR, n = 106); severe on arrival and improved to mild/moderate after ADHF treatment (dynamic MR, n = 149); and mild/moderate at both times (non-significant MR, n = 308). The primary outcome measure was defined as a composite of cardiac death, rehospitalization for heart failure, and mitral valve intervention within 1-year. RESULTS: The incidence of the primary outcome measure in the dynamic MR group (44.8%) was significantly higher than that in the non-significant MR group (22.1%, adjusted hazard ratio [HR]: 0.50, 95% confidence interval [CI]: 0.34-0.73, P < 0.001), and similar to that in the persistent MR group (44.4%, adjusted HR: 1.08, 95% CI: 0.69-1.67, P = 0.75). The risk of dynamic MR was consistent in the subgroups of patients with reduced (<45%) and preserved left ventricular ejection fraction (Pinteraction = 0.56). CONCLUSIONS: In patients hospitalized for ADHF, dynamic severe MR on hospital arrival was associated with poorer outcomes than non-significant MR and had similar risk to persistent severe MR. Acute dynamic MR is a potential therapeutic target in ADHF patients. PMID- 30274753 TI - Impact of vascular access on the development of contrast induced nephropathy in patients undergoing coronary angiography and/or percutaneous coronary intervention. AB - BACKGROUND: Contrast induced nephropathy (CIN) is a common complication of procedures that foresee the use of contrast media. Several risk factors have been identified as independent predictors of CIN, but, to date, no definitive data are available about the association between the angiographic approach and its development. METHODS AND RESULTS: Our population included 4199 patients undergoing coronary angiography and/or PCI. CIN was defined as an absolute >=0.5 mg/dl or a relative >=25% increase in creatinine level at 24-48 h after the procedure without another clear cause for the acute kidney injury. The total incidence of CIN was 12.4%. We divided our population into two groups, according to the angiographic approach: transradial (TR) n = 1915 or transfemoral (TF) n = 2284. Patients treated with TR approach were more often males, with history of hypertension, and PCI, but less often diabetic, with previous myocardial infarction, coronary artery by-pass graft surgery and cerebrovascular accident. They had a higher ejection fraction, higher prevalence of PCI, elective indication but interestingly a lower amount of contrast volume. Patients treated with TR approach had higher platelets, Total, LDL and HDL cholesterol, but lower triglycerides, glycaemia and basal creatinine. No significant difference was observed between the two groups regarding the development of CIN (TR 13.2% vs TF 11.7%, p = 0.16). The absence of association between angiographic approach and the incidence of CIN was also confirmed at multivariate analysis after correction for baseline confounders (Adjusted OR [95% CI] = 1.2 [0.97-1.50], p = 0.09) and at subgroup analysis according to main risk factors for CIN. Similar results were obtained dividing our population according to propensity score tertiles: 1st Tertile CIN (TF 8.8% vs TR 8.9%), p = 0.95; OR (99% CI) = 1.01 (0.96-1.48), p = 0.95, 2nd Tertile CIN (TF 10.8% vs TR 12.4%), p = 0.35; OR (99% CI) = 1.17 (0.84 1.62), p = 0.35, and 3rd Tertile CIN (TF 15.6% vs TR 17.2%), p = 0.41; OR (99% CI) = 1.12 (0.85-1.48), p = 0.41. CONCLUSION: This is the first large study showing the absence of relationship between the angiographic access and the incidence of CIN. PMID- 30274754 TI - Frailty predicts mortality and complications in chronologically young patients with traumatic orthopaedic injuries. AB - BACKGROUND: As morbidity and mortality from traumatic orthopaedic injuries continues to rise, increased research is being conducted on how to best predict complications in at risk patients. Recently, frailty indices have been validated in a variety of surgical subspecialties as predictors of morbidity and mortality. However, the vast majority of research has been conducted on geriatric patient populations, with little evidence on patients who are chronologically young. The purpose of this study was to evaluate the role of a modified frailty index (mFI) in predicting mortality and complications after pelvis, acetabulum, and lower extremity trauma in patients of all ages. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was queried from 2005 to 2014 for all patients who underwent surgery for pelvis, acetabulum, and lower extremity trauma. The sample size was divided into geriatric (age >= 60) and young (age < 60) cohorts. The mFI score was calculated for each patient. Bivariate analysis was performed using logistic regression and a chi-square test to determine the relationship between mFI and both primary and secondary outcomes while adjusting for age. Univariate analysis and multivariate analyses were performed. All analyses were done using SAS 9.4 (Cary, NC) and a p < 0.05 was considered significant. RESULTS: 56,241 patients were identified to have undergone surgery for pelvis, acetabulum, or lower extremity trauma. 28% of patients were identified under the age of 60. In the young cohort, mFI was a strong predictor of thirty-day mortality (OR 11.02, 95% CI 6.26-19.39, p < 0.001). With regards to Clavien-Dindo grade IV complications, MFI is also a strong predictor in the young cohort (OR 28.82, 95% CI 16.05-51.77, p < 0.001). CONCLUSION AND RELEVANCE: The mFI score was a significant predictor of morbidity and mortality in chronologically young orthopaedic trauma patients. The use of the mFI score can provide an individualized risk assessment to interdisciplinary teams for perioperative counseling and to improve outcomes. PMID- 30274756 TI - Fascia-iliaca compartment block vs intra-articular hip injection for preoperative pain management in intracapsular hip fractures: A blind, randomized, controlled trial. AB - BACKGROUND: The aim of this study was to compare the fascia-iliaca compartment block and the intra-articular hip injection in terms of pain management and the need for additional systemic analgesia in the preoperative phase of intracapsular hip fractures. METHODS: Patients >65 years old with an intracapsular hip fracture were randomized in this prospective, blind, controlled, parallel trial in a Level I trauma center. Patients were randomly assigned to receive either the fascia iliaca compartment block (cohort FICB) or the intra-articular hip injection (cohort IAHI) upon admission to the emergency department. The primary outcome was pain relief at 20 min, 12 h, 24 h and 48 h after the regional anesthesia, both at rest and during internal rotation of the fractured limb. The Numeric Rating Scale was used. Residual pain was managed with the same protocol in all patients. Additional analgesic drug administration during the 48 h from admission was recorded. RESULTS: A total of 120 patients with comparable baseline characteristics were analyzed in this study: the FICB group consisted of 70 subjects, while the IAHI group consisted of 50 subjects. Pain was significantly lower in the IAHI group during movement of the fractured limb at 20 min (p < 0.05), 12 h (p < 0.05), 24 h (p < 0.05) and 48 h (p < 0.05). In the FICB cohort 72.9% of patients needed to take oxycodone, in contrast to 28.6% of the IAHI cohort (p < 0.05). In the FICB cohort 14.09 +/- 11.57 mg of oxycodone was administered, while in the IAHI cohort 4.38 +/- 7.63 mg (p < 0.05). No adverse events related to either technique were recorded. CONCLUSIONS: Intra-articular hip injection provides better pre-operatory pain management in elder patients with intracapsular hip fractures compared to the fascia-iliaca compartment block. It also reduced the need for supplementary systemic analgesia. LEVEL OF EVIDENCE: Therapeutic Level I. PMID- 30274757 TI - External benchmarking of trauma services in New South Wales: Risk-adjusted mortality after moderate to severe injury from 2012 to 2016. AB - BACKGROUND: Trauma centres and systems have been associated with improved morbidity and mortality after injury. However, variability in outcomes across centres within a given system have been demonstrated. Performance improvement initiatives, that utilize external benchmarking as the backbone, have demonstrated system-wide improvements in outcomes. This data driven approach has been lacking in Australia to date. Recent improvement in local data quality may provide the opportunity to engage in data driven performance improvement. Our objective was to generate risk-adjusted outcomes for the purpose of external benchmarking of trauma services in New South Wales (NSW) based on existing data standards. METHODS: Retrospective cohort study of the NSW Trauma Registry. We included adults (>16 years), with an Injury Severity Score >12, that received definitive care at either Major Trauma Services (MTS) or Regional Trauma Services (RTS) between 2012-2016. Hierarchical logistic regression models were then used to generate risk-adjusted outcomes. Our outcome measure was in-hospital death. Demographics, vital signs, transfer status, survival risk ratios, and injury characteristics were included as fixed-effects. Median odds ratios (MOR) and centre-specific odds ratios with 95% confidence intervals were generated. Centre level variables were explored as sources of variability in outcomes. RESULTS: 14,452 patients received definitive care at one of seven MTS (n = 12,547) or ten RTS (n = 1905). Unadjusted mortality was lower at MTS (9.4%) compared to RTS (11.2%). After adjusting for case-mix, the MOR was 1.33, suggesting that the odds of death was 1.33-fold greater if a patient was admitted to a randomly selected centre with worse as opposed to better risk-adjusted mortality. Definitive care at an MTS was associated with a 41% lower likelihood of death compared to definitive care at an RTS (OR 0.59 95%CI 0.35-0.97). Similar findings were present in the elderly and isolated severe brain injury subgroups. CONCLUSIONS: The NSW trauma system exhibited variability in risk-adjusted outcomes that did not appear to be explained by case-mix. A better understanding of the drivers of the described variation in outcomes is crucial to design targeted locally relevant quality improvement interventions. PMID- 30274755 TI - Open abdomen and entero-atmospheric fistulae: An interim analysis from the International Register of Open Abdomen (IROA). AB - INTRODUCTION: No definitive data describing associations between cases of Open Abdomen (OA) and Entero-atmospheric fistulae (EAF) exist. The World Society of Emergency Surgery (WSES) and the Panamerican Trauma Society (PTS) thus analyzed the International Register of Open Abdomen (IROA) to assess this question. MATERIAL AND METHODS: A prospective analysis of adult patients enrolled in the IROA. RESULTS: Among 649 adult patients with OA 58 (8.9%) developed EAF. Indications for OA were peritonitis (51.2%) and traumatic-injury (16.8%). The most frequently utilized temporary abdominal closure techniques were Commercial NPWT (46.8%) and Bogota-bag (21.9%). Mean OA days were 7.9 +/- 18.22. Overall mortality rate was 29.7%, with EAF having no impact on mortality. Multivariate analysis associated cancer (p = 0.018), days of OA (p = 0.003) and time to provision-of-nutrition (p = 0.016) with EAF occurrence. CONCLUSION: Entero atmospheric fistulas are influenced by the duration of open abdomen treatment and by the nutritional status of the patient. Peritonitis, intestinal anastomosis, negative pressure and oral or enteral nutrition were not risk factors for EAF during OA treatment. PMID- 30274758 TI - Can they stop the bleed? Evaluation of tourniquet application by individuals with varying levels of prior self-reported training. AB - BACKGROUND: Application of extremity tourniquets is a central tenet of multiple national initiatives to empower laypersons to provide hemorrhage control (HC). However, the efficacy of the general population who self-report prior first-aid (FA) or HC training on individual's ability to control bleeding with a tourniquet remains unknown. Therefore, the objective of this study was to assess the effectiveness of laypeople with self-reported prior FA or HC training to control bleeding with a tourniquet. STUDY DESIGN: Employees of a stadium were assessed via simulation in their ability to apply a Combat Application Tourniquet. As a subgroup analysis of a larger study, participants who self-reported: 1) No prior training, 2) FA training only or 2) FA + HC training were compared. Logistic regression adjusting for age, gender, education, willingness-to-assist, and comfort level in HC was performed. RESULTS: 317 participants were included. Compared to participants with no prior training (14.4%,n = 16/111), those with FA training only (25.2%,n = 35/139) had a 2.12-higher odds (95%CI:1.07-4.18) of correct tourniquet application while those with FA + HC (35.8%,n = 24/67) had a 3.50-higher odds (95%CI:1.59-7.72) of correct application. Participants with prior FA + HC were more willing-to-assist and comfortable performing HC than those without prior training (p < 0.05). However, reporting being very willing-to assist [OR0.83,95%CI:0.43-1.60] or very comfortable [OR1.11,95%CI:0.55-2.25] was not associated with correct tourniquet application. CONCLUSION: Self-reported prior FA + HC training, while associated with increased likelihood to correctly apply a tourniquet, results in only 1/3 of individuals correctly performing the skill. As work continues in empowering and training laypeople to act as immediate responders, these findings highlight the importance of effective layperson education techniques. PMID- 30274759 TI - Hip fractures in the oldest old. Comparative study of centenarians and nonagenarians and mortality risk factors. AB - INTRODUCTION: Centenarians and nonagenarians constitute a rapidly growing age group in Western countries and they are expected to be admitted to hospital with hip fractures. The aim of this study was to compare outcomes of centenarian and nonagenarian patients following a hip fracture and to identify risk factors related to in-hospital and post-discharge mortality in both groups. PATIENTS AND METHODS: A prospective evaluation of centenarian patients and nonagenarian controls admitted to a tertiary university hospital in Barcelona with hip fractures over a period of 5 years and 9 months. Baseline characteristics and outcomes in both patient groups were compared. Variables associated with in hospital, 30-day, 3-month and 1-year mortality were also analyzed. RESULTS: Thirty-three centenarians and 82 nonagenarians were included. The most relevant statistically significant differences found were: Barthel index at admission (61.90 vs. 75.22), number of drugs before admission (4.21vs 5.55), in-hospital complication rates (97 vs. 78%), readmissions at 3 months and 1 year (0 vs 11.7% and 3.4 vs. 19.5% respectively) and mortality at 3 months and 1 year (41.4 vs. 20.8% and 62.1 vs. 29.9%, respectively). Mean number of complications, rapid atrial fibrillation, mean age, and urinary tract infection were risk factors associated with mortality. CONCLUSIONS: Centenarian patients had similar in hospital outcomes to nonagenarians, but experienced more complications and twice the 3-month and 1-year mortality rate. The mean number of complications was the risk factor most consistently related to in-hospital and post-discharge mortality. These findings emphasize the need to improve care in very old patients to prevent complications. PMID- 30274760 TI - Peri-mortem caesarean section after traumatic arrest: Crisis resource management. AB - Peri-mortem caesarean section (PMCS) is a very rare procedure performed to improve the chances of survival for both mother and fetus following cardiorespiratory arrest. Non-obstetricians including Emergency Physicians (EPs) are often called upon to perform this procedure under challenging and suboptimal circumstances. We reported a case of PMCS performed timely after traumatic cardiorespiratory arrest that resulted in fetal survival. A 25-year-old primigravida female and six-month pregnant presented to the Emergency Department (ED) of an adult tertiary hospital. She experienced traumatic cardiorespiratory arrest for nearly 27 min following a high-speed motor vehicle crash. Upon ED arrival, she was in pulseless electrical activity. She was immediately intubated with continuation of cardiopulmonary resuscitation. She received bilateral tube thoracostomies as well as intravenous (IV) transfusion of blood products, adrenaline and tranexamic acid. Her fundal height was two centimeters above the umbilicus on palpation. The EP performed a PMCS via a midline laparotomy 3-4 min upon ED arrival. The baby was bradycardic and cyanosed with no spontaneous respiration at birth and was resuscitated by a second EP. She was intubated and the EP gained IV access using a cannula introduced into the umbilical vein. Neonatal hypothermia was avoided using cling wrap. The baby was transported to a nearby neonatal intensive unit. She survived and is currently one year old. The mother, however, did not respond to our resuscitation and succumbed to her multiple injuries. We reviewed the limited literature regarding this potentially life-saving emergency procedure and highlighted the challenges facing our resuscitation team.

AB - Clinical practice guidelines recommend protamine sulfate for reversal of enoxaparin associated bleeds dependent on the time from last administration and dose of enoxaparin. We present a case of a hemodynamically unstable patient with an enoxaparin induced abdominal wall hematoma/hemorrhage and the previous enoxaparin administration 21.5 h prior to presentation with a therapeutic anti-Xa assay (0.8 IU/mL) upon assessment in the emergency department. Along with resuscitative efforts, an interdisciplinary team collaborated to administer protamine sulfate 50 mg intravenous once (0.5 mg per 1 mg of enoxaparin) to reverse the therapeutic anticoagulation. Our case demonstrates the importance of monitoring renal function and the potential for accumulation of enoxaparin in patients with renal dysfunction leading to prolonged therapeutic anti-Xa assays. With the availability of anti-Xa assays, future reversal recommendations of enoxaparin associated bleeds using protamine sulfate should include the initial anti-Xa assay as a guide for the dosing regimen.

AB - A 52-year-old patient with multiple cardiovascular risk factors referred for unilateral, acute, and painless visual loss. In the fundoscopic image there was significant papillary inflammation with tortuosity at this level and haemorrhages. Ophthalmological examination showed papillary inflammation, macular oedema, and involvement in retinal inner layers. The control fluorescein angiography and optical coherence tomography angiography showed areas of central and peripheral ischaemia. Given the clinical findings and background of the patient, the diagnosis of Purtscher-like retinopathy was reached and treatment with intravitreal dexamethasone was decided. Purtscher-like retinopathy is a rare entity that occurs in patients with multiple systemic pathologies, but without a traumatic background, which differentiates it from Purstcher's retinopathy. The diagnosis and early intervention are important in the prognosis. There are no therapeutic protocols, but good results have been obtained with intravitreal therapy with dexamethasone. PMID- 30274766 TI - Outcomes for Patients with Non-metastatic Triple-negative Breast Cancer in New Zealand. AB - AIMS: Triple-negative breast cancer (TNBC) has inferior outcomes to other subtypes of breast cancer. We studied the demographics and baseline breast cancer characteristics of patients in New Zealand with TNBC and assessed survival outcomes and prognostic/predictive factors. MATERIALS AND METHODS: We searched the New Zealand breast cancer registry database and identified patients with TNBC without distant metastatic disease. We retrieved demographic, tumour characteristic and treatment information. Locoregional recurrence-free survival, breast cancer-specific survival (BSS), metastasis-free survival (MRFS) and overall survival were determined. Predefined univariate and multivariate analyses were carried out investigating the association of survival outcomes with treatment and tumour characteristics. RESULTS: In total, 1390 patients were identified, with a median follow-up of 3.5 years. The median age was 55 years. Thirty-eight per cent were node positive and 79% were grade III. Mastectomy was carried out in 53%, adjuvant radiation delivered in 66% and chemotherapy in 69%. The significant predictive factors for overall survival, BSS and MRFS were radiotherapy, chemotherapy and neoadjuvant chemotherapy. The significant prognostic indicators were lymphovascular invasion, nodal status and tumour size. On Kaplan-Meier analysis, the 5 year overall survival was 72%. The median time to death for those who died was 3.55 years with 92% of deaths within 5 years. Seventy-four per cent of patients had distant metastasis as a first recurrence and isolated local recurrences occurred in only 4.5%. Metastatic disease occurred in lung (55.9%) and was in multiple sites in 51%. CONCLUSION: We report a large population-based series of TBNC without distant metastatic disease at diagnosis highlighting the unique behavioural characteristics of TNBC. Traditional therapies are positively associated with survival outcomes, and yet, particularly in the setting of recurrent disease, prognosis remains poor. Increased research into more effective systemic agents and the most effective timing of delivery of these may result in improved outcomes. PMID- 30274767 TI - Evaluation of Response to Stereotactic Radiosurgery in Brain Metastases Using Multiparametric Magnetic Resonance Imaging and a Review of the Literature. AB - AIMS: Following stereotactic radiosurgery (SRS), brain metastases initially increase in size in up to a third of cases, suggesting treatment failure. Current imaging using structural magnetic resonance imaging (MRI) cannot differentiate between tumour recurrence and SRS-induced changes, creating difficulties with patient management. Combining multiparametric MRI techniques, which assess tissue physiological and metabolic information, has shown promise in answering this clinical question. MATERIALS AND METHODS: Multiparametric MRI techniques, including spectroscopy, diffusion and perfusion imaging, were used for the differentiation of radiation-related changes and tumour recurrence after SRS for intracranial metastases in six cases. All patients presented with enlargement of the treated lesion, an increase in perilesional brain oedema and aggravation or appearance of neurological signs and symptoms from 7 to 29 weeks after primary treatment. RESULTS: Multiparametric imaging helped to differentiate features of tumour progression (n = 4) from radiation-related changes (n = 2). A low apparent diffusion coefficient (ADC) <1000 * 10-6 mm2/s, high relative cerebral blood volume (rCBV) ratio > 2.1, high choline:creatine (Cho:Cr) ratio > 1.8 suggested tumour recurrence. A high ADC > 1000 * 10-6 mm2/s, low rCBV ratio < 2.1, Cho:Cr ratio < 1.8 suggested SRS-induced radiation changes. Multiparametric MRI diagnosis was confirmed by histology or radiological and clinical follow-up. CONCLUSION: Multiparametric MRI was helpful in the early identification of radiation-related changes and tumour recurrence and may be useful for monitoring treatment changes in intracranial neoplasms after SRS treatment. PMID- 30274768 TI - Extended Cardiac Monitoring in Patients With Severe Sleep Apnea and No History of Atrial Fibrillation (The Reveal XT-SA Study). AB - Atrial fibrillation (AF) is a risk factor for ischemic stroke and reported to be associated with severe obstructive sleep apnea (OSA). The aim of this study was to determine the occurrence of newly detected AF in patients with severe OSA and no previous history of AF. Prospective observational study included patients with severe OSA (Apnea-Hypopnea Index [AHI] >= 30) and no history of AF. Primary outcome was detection of AF lasting >=10 seconds. Patients were subjected to 2 24 hour Holter monitors, and if no AF was detected, implanted with a Medtronic Reveal XT implantable loop recorder. Follow-up was done every 6 months for a total of 3years. Implantable loop recorder was explanted if the primary outcome was detected (AF) or the battery was exhausted. Of the 31 patients enrolled, 6 withdrew participation in the study before implantation. Mean age was 57 +/- 10years, mean body mass index was 35 +/- 6; 52% male patients. Hypertension 56% and coronary artery disease 24%. Mean AHI was 55 +/- 18. AF was detected in 5 patients (20%). AF mean duration was 4.8hours (range 20 seconds to 15.3 hours). Mean time to diagnosis was 11 +/- 7 months. Male gender was predictive for AF detection (p = 0.04). Continuous positive airway pressure therapy was used by 96% of patients with 68% total adherence. Mean follow-up was 27 months. In conclusion, extended cardiac monitoring of patients with severe OSA may facilitate the identification of newly detected AF. PMID- 30274769 TI - Regulated acetylation and deacetylation of H4 K16 is essential for efficient NER in Saccharomyces cerevisiae. AB - Acetylation status of H4 K16, a residue in the histone H4 N-terminal tail plays a unique role in regulating chromatin structure and function. Here we show that, during UV-induced nucleotide excision repair H4 K16 gets hyperacetylated following an initial phase of hypoacetylation. Disrupting H4 K16 acetylation deacetylation by mutating H4 K16 to R (deacetylated state) or Q (acetylated state) leads to compromised chromatin functions. In the silenced mating locus and telomere region H4 K16 mutants show higher recruitment of Sir proteins and spreading beyond the designated boundaries. More significantly, chromatin of both the H4 K16 mutants has reduced accessibility in the silenced regions and genome wide. On UV irradiation, the mutants showed higher UV sensitivity, reduced NER rate and altered H3 N-terminal tail acetylation, compared to wild type. NER efficiency is affected by reduced or delayed recruitment of early NER proteins and chromatin remodeller Swi/Snf along with lack of nucleosome rearrangement during repair. Additionally UV-induced expression of RAD and SNF5 genes was reduced in the mutants. Hindered chromatin accessibility in the H4 K16 mutants is thus non-conducive for gene expression as well as recruitment of NER and chromatin remodeller proteins. Subsequently, inadequate nucleosomal rearrangement during early phases of repair impeded accessibility of the NER complex to DNA lesions, in the H4 K16 mutants. Effectively, NER efficiency was found to be compromised in the mutants. Interestingly, in the transcriptionally active chromatin region, both the H4 K16 mutants showed reduced NER rate during early repair time points. However, with progression of repair H4 K16R repaired faster than K16Q mutants and rate of CPD removal became differential between the two mutants during later NER phases. To summarize, our results establish the essentiality of regulated acetylation and deacetylation of H4 K16 residue in maintaining chromatin accessibility and efficiency of functions like NER and gene expression.

AB - High blood pressure in individuals with type2 diabetes mellitus increases the risk of cardiovascular events. The international management guidelines recommend starting pharmacological treatment with blood pressure values >140/90mmHg. However, there is no optimal cut-off point from which cardiovascular events can be reduced without causing adverse events. A blood pressure range of >130/80 to <140/90mmHg seems to be adequate. These values can be achieved through non pharmacological (diet, exercise) and pharmacological interventions (using drugs that have been shown to reduce cardiovascular events). The choice of one or several drugs must be individualised, according to factors including, ethnicity, age, and associated comorbidities, among others. PMID- 30274774 TI - The galectin LEC-5 is a novel binding partner for RAB-11. AB - RAB-11/Rab11 is an endosomal GTPase with conserved roles in directional trafficking and apical domain formation in polarized epithelial cells. From a yeast two-hybrid screen using full-length C. elegans RAB-11 as bait, we identified LEC-5 as a novel binding protein for RAB-11. LEC-5 is an ortholog of mammalian Galectin-9 which associates with glycosphingolipids and is implicated in apical cargo sorting. We further confirmed the interaction between RAB-11 and LEC-5 via GST-pull down, co-immunoprecipitation and bimolecular fluorescence complementation. In addition, we showed that LEC-5 binds to RAB-11 with its C terminus. Our results indicate a novel role of RAB-11 in apical sorting via LEC 5. Such a role would extend RAB-11's function as a master regulator of apical trafficking and suggest it could translate apical sorting signals into apical vesicle directionality. PMID- 30274773 TI - beta1,6 GlcNAc branches-modified protein tyrosine phosphatase Mu attenuates its tyrosine phosphatase activity and promotes glioma cell migration through PLCgamma PKC pathways. AB - The metastatic potential of malignant tumor has been shown to be correlated with the increased expression of tri- and tetra-antennary beta1,6-N-acetylglucosamine (beta1,6-GlcNAc) N-glycans. In this study, We found that GnT-V expression was negatively correlated with receptor protein tyrosine phosphatase type MU(RPTPMU) in human glioma tissues. To study whether RPTPMU is a novel substance of GnT-V which further affect RPTPMU's downstream dephosphorylation function, we preform lentiviral infection with GnT-V gene to construct stably transfected GnT-V glial cell lines. We found RPTPMU undergone severer cleavage in GnT-V transfected glioma cells compare to Mock cells. RPTPMU intracellular domain fragments increased while beta1,6-GlcNAc-branched N-glycans increased, in consistent with the decrease of RPTPMU's catalytic activity. The results showed that abnormal glycosylation could decrease the phosphorylation activity of PTP MU, and affect PLCgamma-PKC pathways. Both protease inhibitor Furin and N-glycan biosynthesis inhibitor swainsonine could decrease cell mobility in GnT-V-U87 transfectants and other glioma cell lines. All results above suggest increased post-translational modification of RPTPMU N-glycans by GnT-V attenuates its tyrosine phosphatase activity and promotes glioma cell migration through PLCgamma-PKC pathways, and that the beta1,6-GlcNAc-branched N-glycans of RPTPMU play a crucial role in glioma invasivity. PMID- 30274775 TI - Long non-coding RNA OGFRP1 regulates LYPD3 expression by sponging miR-124-3p and promotes non-small cell lung cancer progression. AB - Long noncoding RNA (OGFRP1) has been reported to be involved in the progression of non-small cell lung cancer (NSCLC). However, the expression pattern, functions and molecular mechanisms of OGFRP1 in NSCLC remains unclear. In the present study, we found that OGFRP1 expression was significantly up-regulated in both NSCLC tissues and cell lines, and the upregulation of OGFRP1 expression is a powerful predictor of advanced clinical stage, lymph nodes metastasis and poor prognosis for NSCLC patients. Loss-of-function assay indicated that knockdown of OGFRP1 inhibited proliferation, migration and invasion, and induced apoptosis in vitro. Mechanistically, OGFRP1 could directly bind to miR-124-3p and effectively act as a competing endogenous RNA (ceRNA) for miR-124-3p to promote the expression of the target gene LYPD3. Taken together, OGFRP1 contributed to progression of NSCLC at least partly through upregulating LYPD3 expression by sponging miR-124-3p, indicating that OGFRP1 may be a novel prognostic biomarker and therapeutic target in NSCLC. PMID- 30274776 TI - Protective effect of electro-acupuncture at maternal different points on perinatal nicotine exposure-induced pulmonary dysplasia in offspring based on HPA axis and signal transduction pathway. AB - Perinatal nicotine exposure can not only lead to lung dysplasia in offspring, but also cause epigenetic changes and induce transgenerational asthma. Previous studies have shown that electro-acupuncture (EA) applied to "Zusanli" (ST 36) can improve the lung morphology and correct abnormal expression of lung development related protein in perinatal nicotine exposure offspring. However, it is still unclear whether ST 36 has a specific therapeutic effect and how maternal acupuncture can protect the offspring from pulmonary dysplasia. In this study, we compared the different effect of ST 36 and "Fenglong" (ST 40), which belong to the same meridian, in terms of lung pulmonary function and morphology, PPARgamma, beta-catenin, GR levels in the lung tissues and CORT in the serum of perinatal nicotine exposure offspring, and explored the mechanism of acupuncture based on the maternal hypothalamus-pituitary-adrenal (HPA) axis. It is shown that EA applied to ST 36 could restore the normal function of maternal HPA axis and alleviate maternal glucocorticoid overexposure in offspring, thereby it can up regulate the PTHrP/PPARgamma and down-regulate the Wnt/beta-catenin signaling pathways, and protects perinatal nicotine exposure-induced pulmonary dysplasia in offspring. Its effect is better than that of ST 40. These results are of great significance in preventing perinatal nicotine exposure-induced pulmonary dysplasia in offspring. PMID- 30274777 TI - MiR-374b-5p-FOXP1 feedback loop regulates cell migration, epithelial-mesenchymal transition and chemosensitivity in ovarian cancer. AB - MicroRNAs (miRNAs) are important regulators in tumorigenesis and progression of multiple human cancers, including ovarian cancer (OC). As a member of miRNAs family, miR-374b-5p has been reported to be a tumor suppressive gene in human cancers. In this study, the lower expression of miR-374b-5p was identified in OC tissues and cell liens using quantitative real time PCR (qRT-PCR). Forkhead box protein P1 (FOXP1) can act as an oncogene in human cancers. Mechanism experiments revealed that FOXP1 is a target of miR-374b-5p. Functionally, miR-374b-5p suppressed cell proliferation, migration and epithelial-mesenchymal transition (EMT) in ovarian cancer. Moreover, the sensitivity of OC cells to cisplatin was markedly enhanced by miR-374b-5p. However, FOXP1 reversed However, FOXP1 reversed miR-374b-5p-mediated biological functions. Previous reports demonstrated the inhibitory effect of FOXP1 on transcription FOXP1. Thus, we further examined the effect of FOXP1 on the transcription activity of miR-374b-5p in OC cells. The results showed that FOXP1 decreased miR-374b-5p expression by inhibiting the transcription activity of miR-374b-5p. Rescue assays revealed the regulatory effect of miR-374b-5p-FOXP1 feedback loop on ovarian cancer progression. In conclusion, miR-374b-5p-FOXP1 feedback loop regulates tumor progression and chemosensitivity in ovarian cancer. PMID- 30274778 TI - Low dose Emodin induces tumor senescence for boosting breast cancer chemotherapy via silencing NRARP. AB - PURPOSE: The resistance to 5-FU often limits its clinical effectiveness on breast cancer treatment. Combination therapy thus is employed to overcome this treatment resistance. We here report a potent antitumor effect of Emodin at low dose on chemotherapy sensitivity of MCF-7 breast cancer cells. METHODS: Cell viability, apoptosis, glutathiones (GSH) concentration and Reactive oxygen species (ROS) activity following Emodin and 5-FU treatment was assessed. Cellular senescence following combined treatment and silence of NRARP was examined by senescence associated beta-galactosidase analysis. Western blot analysis was used to determine changes in the expression of p21, p16, p27, E2F1 and NRARP. RESULTS: Low dose Emodin potentiates 5-FU-induced apoptosis of breast cancer cells, in association with inhibition of NRARP, resulting in cellular senescence. RNA interference of NRARP induced cellular senescence in MCF-7 breast cancer cells. Furthermore, the cellular senescence induced by Emodin and 5-FU treatment could be reverted by pcDNA-NRARP. CONCLUSION: These findings provide preclinical evidence for repurposing use of Emodin in combination with chemotherapeutic agents to treat breast cancer as an alternative salvage regimen. PMID- 30274779 TI - Induced protein degradation of anaplastic lymphoma kinase (ALK) by proteolysis targeting chimera (PROTAC). AB - Recently, proteolysis targeting chimera (PROTAC) technology is highlighted in drug discovery area as a new therapeutic approach. PROTAC as a heterobifunctional molecule is comprised of two ligands, which recruit target protein and E3 ligase, respectively. To degrade the anaplastic lymphoma kinase (ALK) fusion protein, such as NPM-ALK or EML4-ALK, we generated several ALK-PROTAC molecules consisted of ceritinib, one of the ALK inhibitors, and ligand of von Hippel-Lindau (VHL) E3 ligase. Among these molecules, TD-004 effectively induced ALK degradation and inhibited the growth of ALK fusion positive cell lines, SU-DHL-1 and H3122. We also confirmed that TD-004 significantly reduced the tumor growth in H3122 xenograft model. PMID- 30274780 TI - SDF-1/CXCR4 axis promotes the growth and sphere formation of hypoxic breast cancer SP cells by c-Jun/ABCG2 pathway. AB - ATP-binding cassette sub-family G member 2 (ABCG2) confers to the major phenotypes of side population (SP) cells, the cancer stem-like cells. In this study, the SP cells displayed a distinctly higher ABCG2 expression level, sphere formation efficiency (SFE) and growth rate even under hypoxia condition. CXCR4 overexpression by pcDNA-CXCR4 transfection robustly increased ABCG2 expression, and promoted SFE and growth of hypoxic SP cells, while CXCR4 inhibitor AMD3100 could suppress the promotion. Additionally, we found that CXCR4 promoted the expression of c-Jun, a major gene in the oncogenic JNK/c-Jun pathway. Our data on electrophoretic mobility shift assay (EMSA) and chromatin immunoprecipitation (ChIP) assays both showed that c-Jun directly bound with the ABCG2 promoter sequence. Moreover, overexpression of JNK/c-Jun promoted ABCG2 expression, SFE, and growth of hypoxic SP cells and the promotion could be rescued by c-Jun inhibitor SP600125. In conclusion, CXCR4 increases the growth and SFE of breast cancer SP cells under hypoxia through c-Jun-mediated transcriptional activation of ABCG2. PMID- 30274781 TI - DNA polymerase beta deficiency in the p53 null cerebellum leads to medulloblastoma formation. AB - Defects in DNA damage response or repair mechanisms during neurogenesis result in genomic instability, which is causative for several neural defects. These include brain tumors, particularly medulloblastoma, which occurs in the cerebellum with a high incidence in children. We generated an animal model with defective base excision repair during brain development through selective inactivation of DNA polymerase beta (Polb) in neuroprogenitor cells. All of Polb conditional knockout mice developed medulloblastoma in a p53 null background, similar to the Xrcc1 and p53 double deficient animal model. XRCC1 is a scaffolding protein which is involved in DNA damage repair and binds to POLB. In both animal models, the histopathological characteristics of the medulloblastoma were similar to those of human classic medulloblastoma. Brain tumor development was slower in the Polb and p53 double null animals than in the Xrcc1 and p53 double knockout animals. Molecular marker analysis suggested that Polb- and Xrcc1-deficient medulloblastomas belonged to the SHHalpha subtype, underscoring the important role of genomic stability in preventing this devastating pediatric cerebellar tumor. PMID- 30274782 TI - Evaluation of collagen mixture on promoting skin wound healing in zebrafish caused by acetic acid administration. AB - The aim of this study is to use zebrafish embryos as a quick platform for wound healing studies. At beginning, we optimized a protocol to induce skin lesion by acetic acid injection. The acetic acid injection induced regional inflammation wound hyperpigmentation by recruiting pigment cells to the wound area. Later, we applied established platform to evaluate the effect of tilapia's collagen peptide mixtures, including demonstration on promoting skin wound healing and eliminating inflammatory response. Results showed that after treating TY001, one of the above fish collagen peptide mixtures, not only repair and proliferation were induced, but also death and apoptosis cells were cleared within cutaneous lesion. Moreover, inflammatory response was suppressed along with collagen mixture treatment. Finally, the TY001-associated signaling was validated by real time PCR, and numbers of gene associated with tissue repair and vessel proliferation were induced. To sum up, our findings provided a permissive model that may apply to generate a platform for further screening on repair and restoration technology. In addition, the tilapia fish collagen peptide mixture we applied on our model has great potential on developing clinical application on wound healing.

AB - Long noncoding RNAs (lncRNAs) have been demonstrated to play a role in carcinogenesis, but their mechanisms of function remain elusive. We explored the mechanisms of the oncogenic role of GCAWKR in gastric cancer (GC) using human tissues and cell lines. The in situ hybridization analysis was utilized to determine GCAWKR levels in samples from 42 GC patients and real-time qPCR in tissues from 123 patients. The GCAWKR levels were modulated in GC cell lines, and relevant biological and molecular analyses were performed. Levels of the GCAWKR were upregulated in GC tissues compared with normal tissues and associated with tumor size, lymph node metastasis, TNM stage, and patient outcomes. GCAWKR affected cell proliferation and cell invasion in multiple GC models. Mechanistically, GCAWKR bound WDR5 and KAT2A and acted as a molecular scaffold of WDR5/KAT2A complexes, modulating the affinity for WDR5/KAT2A complexes in the target gene's promoter region. Thus, our data defined a mechanism of lncRNA mediated carcinogenesis in GC, suggesting new therapeutic targets in GC. PMID- 30274787 TI - MicroRNA-532-5p Regulates Pericyte Function by Targeting the Transcription Regulator BACH1 and Angiopoietin-1. AB - MicroRNAs regulate endothelial function and angiogenesis, but their implication in pericyte biology remains undetermined. A PCR array, covering a panel of 379 human microRNAs, showed microRNA-532-5p to be one of the most differentially modulated by hypoxia, which was confirmed by qPCR in both skeletal muscle and adventitial pericytes. Furthermore, microRNA-532-5p was upregulated in murine muscular pericytes early after experimentally induced ischemia, decreasing below baseline after reperfusion. Transfection of human pericytes with anti-microRNA, microRNA-mimic, or controls indicates microRNA-532-5p modulates pro-angiogenic activity via transcriptional regulation of angiopoietin-1. Tie-2 blockade abrogated the ability of microRNA-532-5p-overexpressing pericytes to promote endothelial network formation in vitro. However, angiopoietin-1 is not a direct target of microRNA-532-5p. In silico analysis of microRNA-532-5p inhibitory targets associated with angiopoietin-1 transcription indicated three potential candidates, BACH1, HIF1AN, and EGLN1. Binding of microRNA-532-5p to the BACH1 3' UTR was confirmed by luciferase assay. MicroRNA-532-5p silencing increased BACH1, while a microRNA-532-5p mimic decreased expression. Silencing of BACH1 modulated angiopoietin-1 gene and protein expression. ChIP confirmed BACH1 transcriptional regulation of angiopoietin-1 promoter. Finally, microRNA-532-5p overexpression increased pericyte coverage in an in vivo Matrigel assay, suggesting its role in vascular maturation. This study provides a new mechanistic understanding of the transcriptional program orchestrating angiopoietin-1/Tie-2 signaling in human pericytes. PMID- 30274786 TI - RNAi-Mediated beta-Catenin Inhibition Promotes T Cell Infiltration and Antitumor Activity in Combination with Immune Checkpoint Blockade. AB - Wnt/beta-catenin signaling mediates cancer immune evasion and resistance to immune checkpoint therapy, in part by blocking cytokines that trigger immune cell recruitment. Inhibition of beta-catenin may be an effective strategy for increasing the low response rate to these effective medicines in numerous cancer populations. DCR-BCAT is a nanoparticle drug product containing a chemically optimized RNAi trigger targeting CTNNB1, the gene that encodes beta-catenin. In syngeneic mouse tumor models, beta-catenin inhibition with DCR-BCAT significantly increased T cell infiltration and potentiated the sensitivity of the tumors to checkpoint inhibition. The combination of DCR-BCAT and immunotherapy yielded significantly greater tumor growth inhibition (TGI) compared to monotherapy in B16F10 melanoma, 4T1 mammary carcinoma, Neuro2A neuroblastoma, and Renca renal adenocarcinoma. Response to the RNAi-containing combination therapy was not dependent on Wnt activation status of the tumor. Importantly, this drug combination was associated with elevated levels of biomarkers of T cell-mediated cytotoxicity. Finally, when CTLA-4 and PD-1 antibodies were combined with DCR BCAT in MMTV-Wnt1 transgenic mice, a genetic model of spontaneous Wnt-driven tumors, complete regressions were achieved in the majority of treated subjects. These data support RNAi-mediated beta-catenin inhibition as an effective strategy to increase response rates to cancer immunotherapy. PMID- 30274790 TI - Recombinant BCG Overexpressing phoP-phoR Confers Enhanced Protection against Tuberculosis. AB - The live tuberculosis vaccine Mycobacterium bovis BCG (Bacille Calmette-Guerin) comprises a number of genetically distinct substrains. In BCG-Prague, phoP of the PhoP-PhoR two-component system is a pseudogene due to a single insertion mutation. We hypothesized that this mutation partially accounts for the low immunogenicity of BCG-Prague observed in the 1970s. In this study, we showed that complementation with the M. bovis allele of phoP restored BCG-Prague's immunogenicity. Furthermore, we showed that overexpression of the M. bovis allele of phoP-phoR in BCG-Japan, a strain already containing a copy of phoP-phoR, further enhanced immunogenicity and protective efficacy. Vaccination of C57BL/6 mice with the recombinant strain rBCG-Japan/PhoPR induced higher levels of interferon-gamma (IFN-gamma) production by CD4+ T cells than that with the parental BCG. Guinea pigs vaccinated with rBCG-Japan/PhoPR were better protected against challenge with Mycobacterium tuberculosis than those immunized with the parental BCG, showing significantly longer survival time, reduced bacterial burdens, and less severe pathology. Taken together, our study has identified a genetic modification that could be generally applied to generate new recombinant BCG vaccines. PMID- 30274789 TI - Engineering the Direct Repeat Sequence of crRNA for Optimization of FnCpf1 Mediated Genome Editing in Human Cells. AB - FnCpf1-mediated genome-editing technologies have enabled a broad range of research and medical applications. Recently, we reported that FnCpf1 possesses activity in human cells and recognizes a more compatible PAM (protospacer adjacent motif, 5'-KYTV-3'), compared with the other two commonly used Cpf1 enzymes (AsCpf1 and LbCpf1), which requires a 5'-TTTN-3' PAM. However, due to the efficiency and fidelity, FnCpf1-based clinical and basic applications remain a challenge. The direct repeat (DR) sequence is one of the key elements for FnCpf1 mediated genome editing. In principle, its engineering should influence the corresponding genome-editing activity and fidelity. Here we showed that the DR mutants [G(-9)A and U(-7)A] could modulate FnCpf1 performance in human cells, enabling enhancement of both genome-editing efficiency and fidelity. These newly identified features will facilitate the design and optimization of CRISPR-Cpf1 based genome-editing strategies. PMID- 30274788 TI - Therapeutic Genome Editing for Myotonic Dystrophy Type 1 Using CRISPR/Cas9. AB - Myotonic dystrophy type 1 (DM1) is caused by a CTG nucleotide repeat expansion within the 3' UTR of the Dystrophia Myotonica protein kinase gene. In this study, we explored therapeutic genome editing using CRISPR/Cas9 via targeted deletion of expanded CTG repeats and targeted insertion of polyadenylation signals in the 3' UTR upstream of the CTG repeats to eliminate toxic RNA CUG repeats. We found paired SpCas9 or SaCas9 guide RNA induced deletion of expanded CTG repeats. However, this approach incurred frequent inversion in both the mutant and normal alleles. In contrast, the insertion of polyadenylation signals in the 3' UTR upstream of the CTG repeats eliminated toxic RNA CUG repeats, which led to phenotype reversal in differentiated neural stem cells, forebrain neurons, cardiomyocytes, and skeletal muscle myofibers. We concluded that targeted insertion of polyadenylation signals in the 3' UTR is a viable approach to develop therapeutic genome editing for DM1. PMID- 30274791 TI - Quantification of circulating miR-125b-5p predicts survival in chronic hepatitis B patients with acute-on-chronic liver failure. AB - AIMS: To analyze the role of serum miR-125b-5p in reflecting liver damage and predicting outcomes in chronic hepatitis B (CHB) patients with acute-on-chronic liver failure (ACLF). METHODS: CHB patients with normal hepatic function (n = 100), moderate-to-severe liver damage (n = 90), and ACLF (n = 136) were included. Among hepatitis B virus (HBV)-ACLF patients, 86 and 50 were in the training and validation cohorts, respectively. Serum miR-125b-5p level was measured by quantitative real-time PCR. RESULTS: Serum miR-125b-5p level increased with disease progression, and serum miR-125b-5p level was lower in surviving than in dead HBV-ACLF patients. Among HBV-ACLF patients, miR-125b-5p positively correlated with total bilirubin (TBil; r = 0.214, p < 0.05) and model for end stage liver disease (MELD) score (r = 0.382, p < 0.001) and negatively correlated with prothrombin activity(PTA; r = -0.215, p < 0.05). MiR-122 showed a contrasting performance compared with miR-125b-5p. Cox regression analysis showed that miR-125b-5p, miR-122, and PTA were independent survival predictors for HBV ACLF, and low miR-125b-5p and high miR-122 levels may predict a longer survival in HBV-ACLF. MiR-125b-5p (AUC = 0.814) had a higher performance for survival prediction in HBV-ACLF compared with miR-122 (AUC = 0.804), PTA (AUC = 0.762), MELD score (AUC = 0.799), and TBil (AUC = 0.670) alone; predictive effectiveness of miR-125b-5p was increased by combination with miR-122 (AUC = 0.898). MiR-125b 5p was an effective predictor of HBV-ACLF outcomes in the validation cohort. CONCLUSIONS: MiR-125b-5p increase is associated with severity of liver damage; high serum miR-125b-5p may serve as a predictor for poor outcomes in HBV-ACLF cases.

AB - BACKGROUND: Fractional flow reserve (FFR)-derived from computed tomography angiography (CTA; FFRCT) and invasive FFR (FFRINV) are used to assess the need for invasive coronary angiography (ICA) and percutaneous coronary intervention (PCI). The optimal location for measuring FFR and the impact of measurement location have not been well defined. METHODS: 930 patients (age 60.7 + 10 years, 59% male) were included in this study. Normal and diseased coronary arteries were classified into stenosis grades 0-4 in the left anterior descending artery (LAD, n = 518), left circumflex (LCX, n = 112) and right coronary artery (RCA, n = 585). FFRCT (n = 1215 arteries) and FFRINV (n = 26 LAD) profiles were developed by plotting FFR values (y-axis) versus site of measurement (x-axis: ostium, proximal, mid, distal segments). The best location to measure FFR was defined relative to the distal end of the stenosis. FFR <=0.8 was considered positive for ischemia. RESULTS: In normal and stenotic coronary arteries there are significant declines in FFRCT and FFRINV from the ostium to the distal vessel (p < 0.001), due to lesion-specific ischemia and to effects unrelated to the lesion. A reliable location (distal to the stenosis) is 10.5 mm [IQR 7.3-14.8 mm] for FFRCT and within 20-30 mm for FFRINV. Rates of positive FFR (from the distal vessel) reclassified to negative FFR (distal to the stenosis) are 61% (FFRCT) and 33% (FFRINV). CONCLUSION: FFRCT and FFRINV values are influenced by stenosis severity and the site of measurement. FFR measurements from the distal vessel may over estimate lesion-specific ischemia and result in unnecessary referrals for ICA and PCI. PMID- 30274796 TI - Alterations in enteric calcitonin gene-related peptide in patients with colonic diverticular disease: CGRP in diverticular disease. AB - Diverticular disease (DD) is one of the most prevalent diseases of the large bowel. Lately, imbalance of neuro-muscular transmission has been recognized as a major etiological factor for DD. Neuronal calcitonin gene-related peptide (CGRP) is a potent gastrointestinal smooth muscle relaxant shown to have a widespread effect within the alimentary tract. Nevertheless, CGRPergic innervation of the enteric ganglia has never been considered in the context of motility impairment observed in DD patients. Changes in CGRP and calcitonin receptor-like receptor (CRLR) abundance within enteric ganglia were investigated in sigmoid samples from symptomatic and asymptomatic DD patients using quantitative fluorescence microscopy. CGRP effect on gastrointestinal smooth muscle was investigated using organ bath technique. We found CGRP levels within the enteric ganglia to be declined by up to 52% in symptomatic DD patients. Conversely, CRLR within the enteric ganglia was upregulated by 41% in symptomatic DD. Longitudinal smooth muscle displayed an elevated (+10.5%) relaxant effect to the exogenous application of CGRP in colonic strips from symptomatic DD patients. Samples from asymptomatic DD patients consistently showed intermediate values across different experiments. In conclusion, the present study demonstrates that CGRPergic signaling is subject to alteration in DD. Our results suggest that a hypersensitization mechanism to gradually decreasing levels of CGRP-IR nerve fibers takes place during DD progression. Alterations to CGRPergic signaling in DD disease may have implications for physiological abnormalities associated with colonic DD. PMID- 30274797 TI - Screening of microorganisms producing a novel protein-asparaginase and characterization of the enzyme derived from Luteimicrobium album. AB - A screening system using enrichment culture has been established with the aim of obtaining a novel enzyme for protein modification that has not been previously reported. This enzyme catalyzes deamidation of the side-chain amide group of asparagine in proteins. Enrichment culture of 390 soil samples was carried out with Z-Asn-Gly as the sole source of nitrogen, and the reaction product, Z-Asp Gly, was detected in the culture supernatant of 102 strains. Strains with particularly high activity were Leifsonia sp., Luteimicrobium sp., Microbacterium sp., and Agromyces sp., all belonging to the class Actinobacteria. Of these, a protein-asparaginase (PA) was obtained from the culture supernatant of Luteimicrobium album 333B-h1, and its reactivity with different substrates and its basic enzymatic characteristics were investigated. Addition of the enzyme solution resulted in specific deamidation of only the asparagine residue in insulin chain B. The enzyme showed no reactivity with free asparagine or asparagine in low molecular weight peptides. It was demonstrated that the enzyme reacts with various protein substrates. In particular, proteins that have open structures, such as casein or gelatin, were good substrates. The activity and stability of PA at different temperatures and pH values were investigated. It was found that a temperature of 37 degrees C and a roughly neutral pH are optimal conditions for the enzyme. PMID- 30274798 TI - Targeted proteome analysis of microalgae under high-light conditions by optimized protein extraction of photosynthetic organisms. AB - Cell disruption and protein solubilization protocols for the relative quantification of individual subunits in photosystems were developed for photosynthetic organisms including cyanobacterium Synechocystis sp. PCC 6803, green-algae Chlamydomonas reinhardtii, and seed plant Arabidopsis thaliana. The optimal methods for the disruption of Chlamydomonas, Synechocystis, and Arabidopsis cells were sonication, microbeads (Phi approximately 0.1 mm), and large beads (Phi = 5.0 mm), respectively. Extraction of the total proteins exceeded 90% using each optimal cell disruption method. Solubilization efficiency of membrane proteins was improved by the phase transfer surfactant (PTS) method. Ninety seven and 114 proteins from Chlamydomonas and Synechocystis, respectively, including membrane proteins such as photosystem proteins, ATP synthase, and NADH dehydrogenase, were successfully analyzed by nano-liquid chromatography tandem mass spectrometry. These results also indicated the improved efficiency of solubilization and trypsin digestion using PTS buffer. The results of the relative quantitative evaluation of photosystem subunits in Chlamydomonas and Synechocystis grown under high-light conditions were consistent with those of previous studies. Thus, the optimal cell disruption and PTS methods allow for comprehensive relative quantitative proteome analysis of photosynthetic organisms. Additionally, NdhD1 and NdhF1, which are NDH-1 subunit homologs, were increased under high-light conditions, suggesting that the NDH-1L complex, including NdhD1 and NdhF1, is increased under high-light conditions. The relative quantitative proteome analysis of individual subunits indicates the diverse functions of NDH-1 protein. PMID- 30274799 TI - Cultural Humility for Consultation-Liaison Psychiatrists. AB - BACKGROUND: Case presentation and analysis is a useful way to revisit key clinical themes, broad concepts, and teach others, especially when it comes to cross-cultural clinical issues. Patients from different cultural backgrounds tend to have different explanatory models of illnesses and related help seeking behaviors. Ineffective communication between clinicians and patients from nonmajority cultural groups may lead to less satisfaction with care and disparities in access to health care and in treatment outcomes. CONCLUSIONS: To address health disparities, psychiatrists need to be able to understand the illness beliefs of all patients, particularly those from diverse cultural backgrounds. Using cultural humility to work with patients from all cultures by understanding the patients' values and preferences is a key attitude for successful cross-cultural clinical encounters.

AB - BACKGROUND: Surgical follow-up allows patients to discuss pathology and preventative maintenance. Multiple factors impact patients' compliance with surgical follow-up. We hypothesized that increased travel time would be associated with lack of post-discharge surgical follow-up. METHODS: Retrospective analysis identified patients undergoing laparoscopic appendectomy or laparoscopic cholecystectomy. Descriptive statistics and logistic regression assessed the relationship between patient characteristics and post-discharge follow-up. RESULTS: We identified 1830 patients from 2015-2016. 31% did not complete follow up, were more likely to have had an appendectomy, be un- or underinsured, not married, and live outside North Carolina. Median round-trip travel time was not significantly different. After adjustment for patient factors, each additional 10 min of travel time increased the odds of not following up by 6% (p < 0.01). CONCLUSIONS: Travel time was the only modifiable factor associated with post discharge follow-up. Novel methods of completing follow-up that minimize travel time, such as virtual visits, may increase compliance with recommended follow-up. PMID- 30274804 TI - Does a fracture liaison service program minimize recurrent fragility fractures in the elderly with osteoporotic vertebral compression fractures? AB - BACKGROUND: There is a sizable proportion of elderly, both men and women, with fragility fractures, approximately 2 million fractures per year in the United States. METHODS: A retrospective chart review of 365 patient presented between January 2012 and December 2017 with vertebral compression fractures. Pre-post study design to determine refracture between Group A (before Fracture Liaison Service (FLS)) and Group B, after. Calcium, Vitamin D, DEXA scans, FRAX scores, and refracture rates were measured. RESULTS: Mean age for group A and B were 79.0 and 74.9 years, respectively, and predominantly females. Serum calcium was higher in group B (9.51 mg/d/L versus 9.40 mg/dL) but not significant (p = 0.19). Fracture score among the groups was similar (20% versus 22%; p = 0.44). The total refracture rate for both vertebral and other fracture was significantly less in the post FLS patients, 36.5% versus 56% p-value = 0.01. CONCLUSION: FLS program benefited patients with fragility fractures by decreasing the incidence of all refracture rates.

AB - Chronic kidney disease patients have a high prevalence of vitamin D insufficiency/deficiency. Vitamin D deficiency has been associated with a variety of bone, metabolic and cardiovascular disorders. However, the role of native vitamin D supplementation (ergocalciferol, cholecalciferol or calcifediol) remains unclear in chronic kidney disease (CKD), particularly in the pre-dialytic phase. Several international guidelines have been developed on CKD-Mineral and Bone Disorder, but the optimal strategy for native vitamin D supplementation and its clinical benefit remains a subject of debate in the scientific community. This paper aims to review the available literature, including randomized clinical trials that evaluated the effects of native vitamin D supplementation on pre dialysis CKD on biochemical and clinically relevant outcomes. PMID- 30274807 TI - The effects of pressure intervention on wound healing and scar formation in a Bama minipig model. AB - Pressure therapy has been widely used in clinical practice for the prevention or treatment of hypertrophic scars resulted from aberrations in wound healing. However, the precise molecular mechanisms of this process are only partially understood. In the present study, we established a Bama minipig model to observe the effect of pressure intervention on wound healing and scar formation. Transcriptome sequencing was performed to analyze the gene expression profiles in the injured and pressure-treated tissues. Furthermore, expression of the critical factors associated with IGF-1/IGF-1R pathways including PI3K/AKT and MEK/ERK and collagens were further analyzed by quantitative polymerase chain reaction (q-PCR) and Western blot. We observed that the mRNA expression of IGF-1 and IGF-1R were down-regulated in the pressure treated groups. Following pressure intervention, the trend in expression of PI3K/AKT decreased, whereas that of MEK/ERK expression increased, when quantified by q-PCR. Moreover, the level of PI3K protein expression decreased significantly after pressure treatment for one month but there was no significant difference in AKT protein expression. Interestingly, the trend in MEK/ERK protein expression was opposite to that indicated by q-PCR analysis. Furthermore, collagen I and III mRNA clearly declined after one month pressure treatment. Taken together, these results indicated that pressure intervention alleviated scar formation may via inhibiting the IGF-1/IGF-1R signaling pathway and collagen expression in the Bama minipig model. PMID- 30274809 TI - The effect of oral N-acetylcystein on prevention of extensive tissue destruction in electrical burn injury. AB - BACKGROUND: Electric burn patients usually suffer permanent injury and sequelae. Salvage of the zone of stasis is an important topic in the treatment of burn patients. N-Acetylcysteine (NAC), as an antioxidant, has effect on the saving zone of stasis and extensive rhabdomyolisis. The aim of this study was therefore to evaluate the effect of oral NAC on tissue destruction indicators in an electric burn rat model. MATERIAL AND METHODS: An experimental study was conducted with thirty six male Wistar albino rats divided into 2 groups. Group A (n=18) and group B (n=18) were electrical burn injury groups without and with NAC therapy, respectively. The extent of burn wounds were evaluated by planimetry using a digital wound measuring device. Blood samples were obtained to analyze creatine kinase (CK) levels as a marker of extensive rhabdomiolysis on the first hour after electric injury (baseline) and on the 7th day to see the antioxidant effect of NAC. RESULTS: A significant decrease in tissue destruction was seen by the necrotic area on day 7 in the NAC therapy group compared to the control group (mean 2.26+/-1.05cm2 versus mean 7.12+/-3.30cm2 respectively; p=0.001), which was confirmed by the level of serum CK (day 7: group A, mean 140+/-51U/L versus Group B, mean 102+/-6U/L; p=0.007). CONCLUSION: A decrease in electric burn necrotic area and tissue damage in the group using NAC treatment was demonstrated. NAC might have a beneficial effect in the treatment of electrical burns. Further experimental and clinical studies with NAC treatment are necessary to confirm these results. PMID- 30274808 TI - The time-course of the inflammatory response to major burn injury and its relation to organ failure and outcome. AB - Burn injury causes major inflammatory activation and cytokine release, however, the temporal resolution of the acute and sub-acute inflammatory response has not yet been fully delineated. To this end, we have quantified 20 inflammatory mediators in plasma from 44 adult patients 0-21 days after burn injury and related the time course of these mediators to % total body surface area (TBSA) burned, clinical parameters, organ failure and outcome. Of the cytokines analyzed in these patients, interleukin 6 (IL-6), IL-8, IL-10 and monocyte chemoattractant protein 1 (MCP-1) correlated to the size of the injury at 24-48h after burn injury. In our study, the concentration of IL-10 had prognostic value in patients with burn injury both measured at admission and at 24-48h after injury. However, simple demographic data such as age, % burned TBSA, inhalation injury and their combination, the Baux score and modified Baux score, outperform most of the cytokines, with the exception of IL-8 and MCP-1 levels on admission, in predicting death. PMID- 30274810 TI - Early clinical complete blood count changes in severe burn injuries. AB - INTRODUCTION: Following a severe burn injury, significant hematologic changes occur that are reflected in complete blood count (CBC) measurements. Our aim for this study was to examine trend in the components of the CBC in severely burned patients over the first week after injury and compare differences in CBC components between survivors and non-survivors. METHODS: A 5-year retrospective review was performed of adult (>=18years) burn patients with a TBSA>=15%. Age, TBSA, gender, mortality, length of hospital stay, ventilator days, and CBC were collected. RESULTS: Over the first week after injury, HBG and HCT decreased. This decrease was due to loss of red blood cells. WBC counts was initially elevated but decreased over the first 4days. PLT also decreased over the first 4days. Non survivors had lower HBG, HCT, RCC, and PLT over the first week compared to survivors. Non-survivors had higher WBC compared to survivors. RDW was elevated during the first week in non-survivors. MPV was elevated at the end of the first week in non-survivors and MPV on day 7 was independently associated with mortality (O.R. 2.01 (1.1-3.7)). Compared to survivors non-survivors received more transfusions of blood products during the first week after injury. CONCLUSION: Burn-injury specific trends in CBC measurements can be used as references to determine expected clinical course of burn patients. Non-survivors have early hematologic differences compared to survivors. PMID- 30274811 TI - Development and validity of the Burns-Child Adult Medical Procedure Interaction Scale (B-CAMPIS) for young children. AB - BACKGROUND: Young children are at increased risk of burn injury and of procedural distress during the subsequent wound care. There are currently few observational measures validated for use with young children during medical procedures. The aim of this research was to adapt the Child-Adult Medical Procedure Interaction Scale Revised (CAMPIS-R) to assess parent-young child interactions during burn wound care by including nonverbal behavioral coding. METHOD: Eighty-seven families of children (1-6years old) were recruited at their first burn dressing change. Potential behaviors were identified through a literature review, consulting health professionals, and direct observation of parents and children during burn wound care. Nonverbal behaviors were coded live, and verbal behaviors were audio recorded for later assessment. RESULTS: Inter-coder reliability was good to excellent for the Burns-CAMPIS (B-CAMPIS). The additional behaviors were correlated with the hypothesized coping, distress, coping-promoting and distress promoting categories of the CAMPIS-R. Some behaviors differed in frequency across child age groups, with older children demonstrating more verbal behaviors. Convergent validity was demonstrated through correlations with previously validated observational parent-child behavior measures, and parent- and nurse- reported measures of child pain and anxiety. Univariate regression analyses demonstrated the child categories of the B-CAMPIS accounted for equal or more of the variance of parent- and nurse- reported child pain and anxiety, compared to the CAMPIS-R. CONCLUSIONS: The B-CAMPIS is a reliable and valid measure, for assessing coping and distress relationships in young children and their families. Pending further validation, the B-CAMPIS assists researchers and clinicians to recognize and target important behaviors to improve young child coping during pediatric burn wound care.

PMID- 30274812 TI - The trend of burn mortality in Iran - A study of fire, heat and hot substance related fatal injuries from 1990 to 2015. AB - INTRODUCTION: Burn injuries are a major cause of preventable mortality worldwide. To implement preventive strategies, a detailed understanding of the rate and trend of fatal burn injuries is needed. The aim of this study was to determine the rate and trend of burn mortality at national and province level in Iran from 1990 to 2015. MATERIALS AND METHODS: The data were retrieved from various sources: the Death Registration System, cemetery databases, the Demographic and Health Survey and three national population and housing censuses. ICD-10 codes were converted to Global Burden of Disease (GBD) codes for comparability. After addressing the incompleteness of death data, statistical methods such as spatio temporal modelling and Gaussian Process Regression (GPR) were applied to estimate the levels and trend of death and cause specific mortality. RESULTS: The number of deaths due to burning across Iran was 80,625, with a male to female ratio of 0.88, 0.94 and 1.14 in 1990, 1995 and 2015, respectively. The annual percentage change of age-standardized death rate from 1990 to 2015 was -5.42% and -4.22% in women and men, respectively. The burn-related age-standardized mortality rate decreased considerably from 5.97 in 1990 to 1.74 per 100,000 in 2015. The mortality rate due to burns was highest among those aged more than 85 years, especially in Ilam province. CONCLUSION: This study showed a decline in burn mortality in Iran from 1990 to 2015. Continued efforts to reduce the burden of burns are needed to accelerate this progress and prevent injuries. PMID- 30274814 TI - Epidemiology of work-related burn injuries presenting to burn centres in Australia and New Zealand. AB - BACKGROUND: Burn injuries to workers can have a devastating impact, however knowledge of the epidemiology of work-related burn injuries in Australia and New Zealand is limited. PURPOSE: To describe epidemiological characteristics of work related burn injuries in Australia and New Zealand, and to compare these with non work-related burns. METHODS: Adult burn injury data, 2009-2016, were extracted from the Burns Registry of Australia and New Zealand. Descriptive statistics were used to describe demographic, injury, management and outcome characteristics. Differences between work-related and non-work-related injuries were assessed using Chi-square and Wilcoxon rank-sum tests. RESULTS: Of 10,574 adult patients treated in burn centres in Australia and New Zealand, 2009-2016, 17% had work related burns. Most work-related cases were male (85%), less than 35 years old (53%), and had sustained flame (33%), scald (30%) or chemicals (17%) burns. Proportions of chemical, scald and electrical burns were greater for work-related than for non-work-related burns, with this being most marked for chemical and electrical burns (17% vs. 3% and 7% vs. 1%, respectively). CONCLUSIONS: Almost one in five cases of working-aged people admitted to Australian and New Zealand burns centres was work-related. Through identification of vulnerable groups, this study informs policy and strategies to minimise occupational burn risk.

AB - BACKGROUND: Oculocutaneous albinism (OCA) is a group of autosomal recessive disorders characterized by reduced melanin that are caused by mutations in the gene encoding tyrosinase (TYR), which is the rate-limiting enzyme in the production of the pigment melanin. Many studies or meta-analyses have suggested an association between the TYR T373K SNP and OCA1, but there is limited biochemical and genetic evidence to support this association. METHODS: We overexpressed TYR-WT and TYR-T373K mutants on HK293T cells and tested the changes of melanin production and tyrosinase activity. Then we generated TYR-K373T knock in (KI) rabbits by microinjection of ssDNA and synthesized RNAs targeting C1118A using CRISPR/Cas9-HDR to observe the formation of melanin. FINDINGS: We demonstrated that the T373K mutation in TYR can reduce tyrosinase activity, leading to an absence of melanin synthesis at the cell-level. The gene-edited TYR K373T rabbits exhibited rescued melanin production in hair follicles and irises, as inferred from the evident decrease in pigmentation in TYR-T373K rabbits, thus providing functional validation of the albinism-associated T373K SNP at the animal level. INTERPRETATION: Our study provides the first animal-level functional validation of the albinism-associated TYR K373T SNP in rabbits, and these results will facilitate gene therapy of OCA1 in pre-clinical settings in the future.

PMID- 30274821 TI - Synergistic effect of Nutlin-3 combined with MG-132 on schwannoma cells through restoration of merlin and p53 tumour suppressors. AB - BACKGROUND: The great majority of sporadic vestibular schwannomas (VSs) are due to the mutations of the NF2 gene encoding merlin. Sporadic VSs exhibit variable growth patterns and only a small fraction of the tumours are fast-growing; however, the underlying mechanisms remain undefined. METHODS: DNA sequencing and dosage analysis were used to identify the NF2 mutation status in sporadic schwannomas. The expression and sub-cellular localization of merlin and p53-MDM2 were assessed by immunoblotting, qRT-PCR and immunofluorescence. In vitro and in vivo studies were performed to reveal the effects of Nutlin-3 (a MDM2 inhibitor) and/or MG-132(a proteasome inhibitor) on schwannomas. The proliferation of schwannoma cells was assessed by CCK-8 assay, EdU staining and Flow cytometry analysis. FINDINGS: Double genetic hits of NF2 tended to occur in fast-growing tumours, characterized by the absence of merlin. The deregulation of p53-MDM2 was demonstrated to mediate merlin-deficient tumour growth, characterized by a nuclear accumulation of stabilized MDM2, contributing to a nuclear export of p53 for degradation. Nutlin-3 blocked the proliferation of schwannoma cells via a cooperative recovery of merlin and p53, accompanied by the shuttling of both proteins from the cytoplasm to the nucleus. We further demonstrated a difference in the sensitivity to Nutlin-3 between schwannoma cells with and without merlin expression. Nutlin-3 combined with MG-132 narrowed this between-group difference and triggered stronger inhibitory effects on the growth of schwannomas through coordinated reactivation of p53. INTERPRETATION: These findings present treatment strategies directed on the pathogenesis of sporadic schwannomas. FUND: National Natural Science Foundation of China. PMID- 30274822 TI - Exhaustive non-synonymous variants functionality prediction enables high resolution characterization of the neurofibromin architecture. AB - BACKGROUND: Neurofibromatosis type I (NF1) is caused by heterozygous loss-of function variants in the NF1 gene encoding neurofibromin which serves as a tumor suppressor that inhibits RAS signaling and regulates cell proliferation and differentiation. While, the only well-established functional domain in the NF1 protein is the GAP-related domain (GRD), most of the identified non-truncating disease-causing variants are located outside of this domain, supporting the existence of other important disease-associated domains. Identifying these domains may reveal novel functions of NF1. METHODS: By implementing inferential statistics combined with machine-learning methods, we developed a novel NF1 specific functional prediction model that focuses on nonsynonymous single nucleotide variants (SNVs). The model enables annotating all possible NF1 nonsynonymous variants, thus mapping the range of pathogenic non-truncating variants at the codon level across the NF1 gene. FINDINGS: The generated model demonstrates high absolute prediction value for missense and splice-site variations (area under the ROC curve of 0.96) outperforming 14 other established models. By reviewing the entire dataset of nonsynonymous variants, two novel domains (Armadillo type fold 1 and 2) were identified as being associated with pathogenicity (OR 1.86; CI 1.04 to 3.34 and OR 2.08; CI 1.08 to 4.04, respectively; P < .05). Specific exons and codons associated with increased pathogenicity were also detected along the gene inside and outside the GRD domain. INTERPRETATION: The developed model, enabled better prediction of pathogenicity for variants in NF1 gene, as well as elucidation of novel NF1 associated domains in addition to the GRD.

PMID- 30274823 TI - Epidemiological and clinical characteristics of Dientamoeba fragilis infection. AB - INTRODUCTION: The characteristics of D. fragilis infection are described, with special focus on the clinical and epidemiological aspects. MATERIALS AND METHODS: A retrospective and descriptive study was performed, including all the patients with Dientamoeba fragilis infection who attended a specialized unit between January 2012 and December 2017. PCR was used to diagnose D. fragilis. Patients were treated with metronidazole or paromomycin and reviewed at four and eight weeks post-treatment. Cure was defined as the negativization of all parasitological tests, in absence of symptoms. RESULTS: 163 patients were diagnosed. The most frequent symptoms were abdominal pain (36.2%), chronic diarrhoea (12.3%), anal itching (10.4%), abdominal discomfort (9.2%), skin disease (8%), acute diarrhoea (4.3%) and vomiting (4.3%). Fifty patients were asymptomatic. Forty-two patients had eosinophilia in blood. Thirty-eight cases (23.3%) had a coinfection by Enterobius vermicularis. One hundred and seven patients received treatment, sixty-one of them with metronidazole and the rest with paromomycin. Ninety-nine patients (91%) were cured. The rate of cure was 100% in the paromomycin group versus 86.8% in the metronidazole group (p=0.005; OR: 1.173 [1.057-1.302]). The absence of cure was associated with E. vermicularis coinfection (p=0.014; OR: 6.167 [1.432-26.563] and with longer duration of the symptoms (175 [+/-159SD]) versus 84 [+/-88SD] days, p=0.014) but multivariable analysis did not confirm these associations. CONCLUSION: Dientamoeba fragilis is an important and underestimated cause of gastrointestinal disease in both the autochthonous and immigrant or traveller population. More studies are needed to clarify its optimal treatment and the role played by E. vermicularis in its transmission and maintenance. PMID- 30274824 TI - Endogenous IL-10 maintains immune tolerance but IL-10 gene transfer exacerbates autoimmune cholangitis. AB - The immunomodulatory effect of IL-10 as an immunosuppressive and anti inflammatory cytokine is well known. Taking advantage of our established mouse model of autoimmune cholangitis using 2-octynoic acid conjugated ovalbumin (2-OA OVA) induction, we compared liver pathology, immune cell populations and antimitochondrial antibodies between IL-10 knockout and wild type mice immunized with 2-OA-OVA. At 10 weeks post immunization, portal inflammation and fibrosis were more severe in 2-OA-OVA immunized IL-10 knockout mice than in wild type mice. This was accompanied by significant higher levels of collagen I and III expression, T, NK and NKT subsets in liver and IgG anti-mitochondrial autoantibodies (AMAs) compared to 2-OA-OVA immunized wild type mice, suggesting that endogenous IL-10 is necessary for the maintenance of immune tolerance in primary biliary cholangitis (PBC). Further, we investigated whether administration of exogenous IL-10 could prevent PBC by administration of IL-10 expressing recombinant adeno-associated virus (AAV-IL-10) either 3 days before or 3 weeks after the establishment of liver pathology. Interestingly, administration of AAV-IL-10 resulted in increased liver inflammation and fibrosis, accompanied by increases in IFN-gamma in liver CD4+ T cell, granzyme B, FasL, and CD107a in liver CD8+ T and NKT cells, and granzyme B and FasL in liver NK cells of AAV-IL 10 administered mice compared with control mice. Furthermore, administration of AAV-IL-10 significantly increased levels of proinflammatory cytokines and chemokines (IFN-gamma, TNF-alpha, CXCL9 and CXCL10) and collagen I and III production in naive mice, together with increase in immune cell infiltration and collagen deposition in the liver, suggesting a role of IL-10 in fibrosis. In conclusion, our data demonstrate that endogenous IL-10 is critical in the maintenance of immune tolerance but exogenous administration of IL-10 exacerbates liver inflammation and fibrosis. Furthermore, the distinctive presence of inflammatory immune cell populations and collagen expression in AAV-IL-10 treated naive mice cautions against the clinical use of exogenous IL-10 in patients with autoimmune cholangitis.

AB - BACKGROUND/PURPOSE: Stimuli from the oral cavity may penetrate through exposed dentinal tubules and evoke inflammatory pulp response. Anti-bacterial and anti inflammatory drugs applied to exposed dentin may infiltrate through the dentinal tubules and cause pulp recovery. This study investigated the dentin permeability of anti-bacterial and anti-inflammation drugs via an in-vitro transwell dentin disc tube model. METHODS: Twenty-seven dentin discs prepared from extracted human molars were collected. Nine kinds of drugs were investigated with three dentin discs in each group. These nine drugs included two anti-bacterial drugs (ampicillin sodium and clindamycin phosphate), two corticosteroids (betamethasone sodium phosphate and hydrocortisone sodium succinate), three non-steroidal anti inflammatory drugs (NSAIDs, piroxicam, lysine acetylsalicylate, and diclofenac sodium), and two natural extracts with anti-inflammatory effect (Ginsenoside Rg1 and Hinokitol). The drugs were introduced to the transwell dentin disc tube model and the 4-hour cumulative release of the drug was detected and recorded by UV visible spectroscopy. RESULTS: We found that ampicilin sodium had better dentin permeability than clindamycin phosphate. Betamethasone sodium phosphate revealed better dentin permeability than hydrocortisone sodium succinate. Lysine acetylsalicylate showed the best dentin permeability among the three NSAIDs. Ginsenoside Rg1 had the best dentin permeability among the nine drugs tested. However, Hinokitiol could not penetrate the dentin disc after 4 h. CONCLUSION: Regarding the dentin permeability, Ginsenoside Rg1 is the best among the seven anti-inflammatory drugs tested and ampicilin sodium is the better one between the two anti-bacterial drugs tested. Therefore, these two drugs may have high potential for treating exposed dentinal tubule diseases. PMID- 30274829 TI - A Hidden Markov Model for Detecting Confinement in Single-Particle Tracking Trajectories. AB - State-of-the-art single-particle tracking (SPT) techniques can generate long trajectories with high temporal and spatial resolution. This offers the possibility of mechanistically interpreting particle movements and behavior in membranes. To this end, a number of statistical techniques have been developed that partition SPT trajectories into states with distinct diffusion signatures, allowing a statistical analysis of diffusion state dynamics and switching behavior. Here, we develop a confinement model, within a hidden Markov framework, that switches between phases of free diffusion and confinement in a harmonic potential well. By using a Markov chain Monte Carlo algorithm to fit this model, automated partitioning of individual SPT trajectories into these two phases is achieved, which allows us to analyze confinement events. We demonstrate the utility of this algorithm on a previously published interferometric scattering microscopy data set, in which gold-nanoparticle-tagged ganglioside GM1 lipids were tracked in model membranes. We performed a comprehensive analysis of confinement events, demonstrating that there is heterogeneity in the lifetime, shape, and size of events, with confinement size and shape being highly conserved within trajectories. Our observations suggest that heterogeneity in confinement events is caused by both individual nanoparticle characteristics and the binding site environment. The individual nanoparticle heterogeneity ultimately limits the ability of interferometric scattering microscopy to resolve molecule dynamics to the order of the tag size; homogeneous tags could potentially allow the resolution to be taken below this limit by deconvolution methods. In a wider context, the presented harmonic potential well confinement model has the potential to detect and characterize a wide variety of biological phenomena, such as hop diffusion, receptor clustering, and lipid rafts. PMID- 30274830 TI - Sphingomyelin Stereoisomers Reveal That Homophilic Interactions Cause Nanodomain Formation. AB - Sphingomyelin is an abundant lipid in some cellular membrane domains, such as lipid rafts. Hydrogen bonding and hydrophobic interactions of the lipid with surrounding components such as neighboring sphingomyelin and cholesterol (Cho) are widely considered to stabilize the raft-like liquid-ordered (Lo) domains in membrane bilayers. However, details of their interactions responsible for the formation of Lo domains remain largely unknown. In this study, the enantiomer of stearoyl sphingomyelin (ent-SSM) was prepared, and its physicochemical properties were compared with the natural SSM and the diastereomer of SSM to examine possible stereoselective lipid-lipid interactions. Interestingly, differential scanning calorimetry experiments demonstrated that palmitoyl sphingomyelin, with natural stereochemistry, exhibited higher miscibility with SSM bilayers than with ent-SSM bilayers, indicating that the homophilic sphingomyelin interactions occurred in a stereoselective manner. Solid-state 2H NMR revealed that Cho elicited its ordering effect very similarly on SSM and ent-SSM (and even on the diastereomer of SSM), suggesting that SSM-Cho interactions are not significantly affected by stereospecific hydrogen bonding. SSM and ent-SSM formed gel-like domains with very similar lateral packing in SSM/Cho/palmitoyloleoyl phosphatidylcholine membranes, as shown by fluorescence lifetime experiments. This observation can be explained by a homophilic hydrogen-bond network, which was largely responsible for the formation of gel-like nanodomains of SSMs (or ent SSM). Our previous study revealed that Cho-poor gel-like domains contributed significantly to the formation of an Lo phase in sphingomyelin/Cho membranes. The results of the study presented here further show that SSM-SSM interactions occur near the headgroup region, whereas hydrophobic SSM-Cho interactions appeared important in the bilayer interior for Lo domain formation. The homophilic interactions of sphingomyelins could be mainly responsible for the formation of the domains of nanometer size, which may correspond to the small sphingomyelin/Cho-based rafts that temporally occur in biological membranes. PMID- 30274831 TI - Diffusion of Exit Sites on the Endoplasmic Reticulum: A Random Walk on a Shivering Backbone. AB - Major parts of the endoplasmic reticulum (ER) in eukaryotic cells are organized as a dynamic network of membrane tubules connected by three-way junctions. On this network, self-assembled membrane domains, called ER exit sites (ERES), provide platforms at which nascent cargo proteins are packaged into vesicular carriers for subsequent transport along the secretory pathway. Although ERES appear stationary and spatially confined on long timescales, we show here via single-particle tracking that they exhibit a microtubule-dependent and heterogeneous anomalous diffusion behavior on short and intermediate timescales. By quantifying key parameters of their random walk, we show that the subdiffusive motion of ERES is distinct from that of ER junctions, i.e., ERES are not tied to junctions but rather are mobile on ER tubules. We complement and corroborate our experimental findings with model simulations that also indicate that ERES are not actively moved by microtubules. Altogether, our study shows that ERES perform a random walk on the shivering ER backbone, indirectly powered by microtubular activity. Similar phenomena can be expected for other domains on subcellular structures, setting a caveat for the interpretation of domain-tracking data. PMID- 30274772 TI - Rivaroxaban or aspirin for patent foramen ovale and embolic stroke of undetermined source: a prespecified subgroup analysis from the NAVIGATE ESUS trial. AB - BACKGROUND: Patent foramen ovale (PFO) is a contributor to embolic stroke of undetermined source (ESUS). Subgroup analyses from previous studies suggest that anticoagulation could reduce recurrent stroke compared with antiplatelet therapy. We hypothesised that anticoagulant treatment with rivaroxaban, an oral factor Xa inhibitor, would reduce the risk of recurrent ischaemic stroke compared with aspirin among patients with PFO enrolled in the NAVIGATE ESUS trial. METHODS: NAVIGATE ESUS was a double-blinded, randomised, phase 3 trial done at 459 centres in 31 countries that assessed the efficacy and safety of rivaroxaban versus aspirin for secondary stroke prevention in patients with ESUS. For this prespecified subgroup analysis, cohorts with and without PFO were defined on the basis of transthoracic echocardiography (TTE) and transoesophageal echocardiography (TOE). The primary efficacy outcome was time to recurrent ischaemic stroke between treatment groups. The primary safety outcome was major bleeding, according to the criteria of the International Society of Thrombosis and Haemostasis. The primary analyses were based on the intention-to-treat population. Additionally, we did a systematic review and random-effects meta analysis of studies in which patients with cryptogenic stroke and PFO were randomly assigned to receive anticoagulant or antiplatelet therapy. FINDINGS: Between Dec 23, 2014, and Sept 20, 2017, 7213 participants were enrolled and assigned to receive rivaroxaban (n=3609) or aspirin (n=3604). Patients were followed up for a mean of 11 months because of early trial termination. PFO was reported as present in 534 (7.4%) patients on the basis of either TTE or TOE. Patients with PFO assigned to receive aspirin had a recurrent ischaemic stroke rate of 4.8 events per 100 person-years compared with 2.6 events per 100 person years in those treated with rivaroxaban. Among patients with known PFO, there was insufficient evidence to support a difference in risk of recurrent ischaemic stroke between rivaroxaban and aspirin (hazard ratio [HR] 0.54; 95% CI 0.22 1.36), and the risk was similar for those without known PFO (1.06; 0.84-1.33; pinteraction=0.18). The risks of major bleeding with rivaroxaban versus aspirin were similar in patients with PFO detected (HR 2.05; 95% CI 0.51-8.18) and in those without PFO detected (HR 2.82; 95% CI 1.69-4.70; pinteraction=0.68). The random-effects meta-analysis combined data from NAVIGATE ESUS with data from two previous trials (PICSS and CLOSE) and yielded a summary odds ratio of 0.48 (95% CI 0.24-0.96; p=0.04) for ischaemic stroke in favour of anticoagulation, without evidence of heterogeneity. INTERPRETATION: Among patients with ESUS who have PFO, anticoagulation might reduce the risk of recurrent stroke by about half, although substantial imprecision remains. Dedicated trials of anticoagulation versus antiplatelet therapy or PFO closure, or both, are warranted. FUNDING: Bayer and Janssen. PMID- 30274833 TI - Local Tension on Talin in Focal Adhesions Correlates with F-Actin Alignment at the Nanometer Scale. AB - Cellular force transmission and mechanotransduction are critical in embryogenesis, normal physiology, and many diseases. Talin plays a key role in these processes by linking integrins to force-generating actomyosin. Using the previously characterized FRET-based talin tension sensor, we observed variations of tension both between and within individual focal adhesions in the same cell. Assembling and sliding adhesions showed gradients with higher talin tension toward the cell center, whereas mature, stable adhesions had uniform talin tension. Total talin accumulation was maximal in high-tension regions; by contrast, vinculin intensity was flat or maximal at the adhesion center, and actin intensity was maximal toward the cell center. To investigate mechanism, we combined talin tension imaging with cellular cryotomography to visualize the correlated actin organization at nanometer resolution. Regions of high talin tension had highly aligned linear actin filaments, whereas regions of low tension had less-well-aligned F-actin. These results reveal an orchestrated spatiotemporal relationship between talin tension, actin/vinculin localization, local actin organization, and focal adhesion dynamics. PMID- 30274832 TI - Bioenergetic Feedback between Heart Cell Contractile Machinery and Mitochondrial 3D Deformations. AB - In the heart, mitochondria are arranged in pairs sandwiched between the contractile machinery, which is the major ATP consumer. Thus, in response to the contraction-relaxation cycle of the cell, the mitochondrial membrane should deform accordingly. Membrane deformations in isolated ATP synthesis or in isolated mitochondria affect ATP production. However, it is unknown whether physiological deformation of the mitochondrial membrane in response to the contraction-relaxation cycle can act as a bioenergetic signaling mechanism between ATP demand to supply. We used both experimental and computational tools to reveal whether bioenergetic feedback exists between heart cell contractile machinery and mitochondrial three-dimensional (3D) deformations. We measured the mitochondrial 3D deformation in contracting rabbit cardiac myocytes and used published data on rat cardiac myocytes. These measurements were an input to a novel biophysics model that includes a description of ionic molecules on the mitochondrial membrane, Ca2+ cycling, and mitochondrial membrane stress. As is the case for rat cardiomyocytes, in rabbit cardiomyocytes, the mitochondrial length contracted and expanded with a similar dynamic as the sarcomere length. In contrast, the mitochondrial width expanded and then contracted with a similar dynamic as the mitochondrial length. Differences in the extent of deformation and fractional deformation between the width- and thick-axes were quantified and interpreted as the degree anisotropy between those respective axes. Finally, the model predicts that significant bioenergetic feedback between heart cell contractile machinery and mitochondrial 3D deformations does exist in unloaded rabbit and rat cells. However, this feedback is not a dominant mechanism in ATP supply to demand matching. PMID- 30274835 TI - HCV core antigen: toward elimination of nucleic acid testing?

AB - A large number of animal models revealed that IL-3 plays an important role for the development of T and B cell-mediated autoimmune diseases. However, little is known about the expression and regulation of IL-3 receptors in human T and B cells and how IL-3 modulates the activation and survival of these cells. We show that the IL-3 receptor CD123 is substantially upregulated on proliferating CD4+ and CD8+ T as well as B cells. Upregulation of CD123 differs between various activators and can be further modulated by cytokines. Exposure of human T and B cells to IL-3 enhances proliferation and survival. IL-3 also induces a shift towards secretion of proinflammatory cytokines in T and B cells and reduces the expression of IL-10 in B cells. Thus IL-3 may have proinflammatory and immunostimulatory properties also in human autoimmune diseases. PMID- 30274834 TI - HCV core antigen as an alternative to HCV RNA testing in the era of direct-acting antivirals: retrospective screening and diagnostic cohort studies. AB - BACKGROUND: Direct-acting antivirals for chronic hepatitis C (HCV) infection have reduced the need for on-treatment HCV RNA monitoring. We assessed the accuracy and cost implications of using HCV core antigen testing to replace HCV RNA testing for confirmation of diagnosis, on-treatment monitoring, and determination of sustained virological response (SVR). METHODS: In a retrospective screening cohort study, de-identified residual serum from unselected samples were obtained from commercial laboratories in Ontario, Canada. Samples from each 5-year age-sex band from birth years 1945-74 collected from Aug 1, 2014, to Feb 28, 2015, were included. All samples that tested positive for HCV antibodies, and 10% of samples that tested negative for HCV antibodies, were tested for HCV core antigen and HCV RNA. A retrospective clinical cohort study was also done using blood samples from patients with confirmed HCV infection collected at four tertiary academic centres: one in Canada, two in Germany, and one in the USA. For assessment of SVR, we included samples from patients who started direct-acting antiviral-based treatment (excluding telaprevir and boceprevir) with or without peginterferon, ribavirin, or both, from Jan 1, 2014, to March 31, 2015. To ensure inclusion of adequate numbers for analysis, patients who relapsed after any treatment regimen were included. Serum samples included in the study were from baseline, week 4 on treatment (only for patients treated with direct-acting antivirals), end of treatment, and week 12 or 24 of follow-up. The sensitivity and specificity of core antigen testing as a diagnostic tool was assessed in the screening cohort, using HCV RNA as a reference. The sensitivity and specificity of core antigen testing as well as its concordance with HCV RNA testing in the clinical cohort was assessed at baseline, week 4 on-treatment, and at weeks 12 or 24 after the end of treatment in patients undergoing therapy with direct-acting antivirals. The cost-effectiveness of core antigen testing with and without confirmatory HCV RNA testing for negative samples was also assessed. FINDINGS: From 10 006 samples in the screening cohort, 75 of 80 viraemic (HCV RNA-positive) samples tested positive for HCV core antigen (sensitivity 94%, 95% CI 86-98), and none of the 993 HCV RNA-negative samples tested positive for HCV core antigen (specificity 100%, 95% CI 94-100). The five viraemic samples that tested negative for HCV core antigen had low corresponding HCV RNA concentrations. In the clinical cohort, two (1%) of 202 baseline samples tested negative for HCV core antigen; one had a low HCV RNA concentration (468 IU/mL), the other had a high HCV RNA concentration (>2 000 000 IU/mL). By week 4 of treatment, HCV core antigen concentrations decreased in all patients but were not predictive of SVR. Although there was good concordance between HCV RNA and HCV core antigen results at 12 weeks after the end of treatment (r=0.97; p<0.0001), three of the 148 patients who achieved SVR at 12 weeks tested HCV core antigen positive. 12 weeks after the end of treatment, HCV core antigen was undetectable in one (1%) of 71 samples from patients who were identified as having relapsed according to HCV RNA detection. On-treatment and end-of-treatment testing of core antigen or HCV RNA provided little clinical value. The use of HCV core antigen testing as a confirmatory diagnostic strategy was cost saving relative to HCV RNA testing, with a reduction of CAD$0.29-3.70 per patient screened depending on whether HCV RNA testing was used to confirm HCV core antigen-negative results. INTERPRETATION: These data support the use of HCV core antigen testing to document HCV viraemia in a cost saving diagnostic algorithm. In a treatment setting, HCV core antigen testing can be used instead of HCV RNA testing for diagnosis and documentation of treatment adherence, but it might not be adequate to determine SVR. This approach might improve access to care, particularly in low-income and middle-income countries. FUNDING: Abbott Diagnostics and Toronto Centre for Liver Disease. PMID- 30274839 TI - Glycan recognition at the saliva - oral microbiome interface. AB - The mouth is a first critical interface where most potentially harmful substances or pathogens contact the host environment. Adaptive and innate immune defense mechanisms are established there to inactivate or eliminate pathogenic microbes that traverse the oral environment on the way to their target organs and tissues. Protein and glycoprotein components of saliva play a particularly important role in modulating the oral microbiota and helping with the clearance of pathogens. It has long been acknowledged that glycobiological and glycoimmunological aspects play a pivotal role in oral host-microbe, microbe-host, and microbe-microbe interactions in the mouth. In this review, we aim to delineate how glycan mediated host defense mechanisms in the oral cavity support human health. We will describe the role of glycans attached to large molecular size salivary glycoproteins which act as a first line of primordial host defense in the human mouth. We will further discuss how glycan recognition contributes to both colonization and clearance of oral microbes.

PMID- 30274840 TI - Cytocompatibility and mechanical properties of surgical sealants for cardiovascular applications. AB - OBJECTIVES: The present study compared physical, mechanical, and biologic characteristics of 4 clinically available surgical sealants for cardiovascular repair. METHODS: BioGlue (Cryolife Inc, Kennesaw, Ga), PreveLeak (Mallinckrodt Pharmaceuticals, St Louis, Mo), Tridyne VS (BD, Franklin Lakes, NJ), and Coseal (Baxter Healthcare Corporation, Westlake Village, Calif) were compared for the following properties: hydrated swelling, cytocompatibility, burst strength, biaxial stretching (elasticity), and in vitro degradation. RESULTS: Sealants showed a wide range of swelling upon hydration. By gravimetric and volumetric measurement, swelling was greatest for Coseal followed by Tridyne VS, BioGlue, and PreveLeak. Tridyne VS was the most cytocompatible based on Alamar Blue assay results, supporting 85% cell survival compared with 36% to 39% survival with the other sealants. All sealants withstood pressure above mean arterial pressure (70 110 mm Hg) and physiologic systolic blood pressure (90-140 mm Hg) in an ex vivo arterial flow burst model; lowest peak pressure at failure was PreveLeak at 235 +/- 48 mm Hg, and highest peak pressure at failure was BioGlue at 596 +/- 72 mm Hg. Biaxial tensile testing showed no differences in elasticity between ex vivo porcine aorta and carotid arteries and Tridyne VS or Coseal, and BioGlue and PreveLeak were significantly stiffer. In vitro degradation time for Coseal was 6 days and 21 days for Tridyne VS. No degradation was observed in BioGlue or PreveLeak for 30 days. CONCLUSIONS: Although all sealants withstood supraphysiologic arterial pressure, there were differences in characteristics that may be important in clinical outcome. Coseal degradation time was short compared with other sealants, whereas BioGlue and PreveLeak showed a significant compliance mismatch with native porcine carotid artery. Tridyne VS was significantly more cytocompatible than the other 3 sealants. PMID- 30274842 TI - Atypical endophthalmitis after intraocular collamer lens implantation. AB - Unilateral endophthalmitis occurred after bilateral immediately sequential intraocular collamer lens (Visian Implantable Collamer Lens) implantation for the correction of myopic astigmatism in a 49-year-old woman. The surgeries and initial recovery were unremarkable. However, after 3 days, the patient noticed increasing blurring of vision in the left eye and presented to our clinic. The anterior segment of this eye was quiet, while the vitreous cavity was densely infiltrated. Immediate explantation of the corrective lens and vitrectomy combined with intravitreal antibiotic injection were performed. Staphylococcus epidermidis was detected in the vitreous tap and treated with intravenous antibiotics, antibiotic eyedrops, and parabulbar injections of dexamethasone. The corrected distance visual acuity recovered to 20/20 over a 6-month period. However, a cataract developed thereafter. PMID- 30274843 TI - Analysis of corneal higher-order aberrations in cataract patients with high myopia. AB - PURPOSE: To evaluate the differences in corneal higher-order aberrations (HOAs) between cataract patients with high axial myopia and normal cataract patients, and to identify the associated factors. SETTING: Department of Ophthalmology and Vision Science of the Eye and ENT Hospital of Fudan University, Shanghai, China. DESIGN: Retrospective case series. METHODS: Corneal aberrations and axial lengths (ALs) were measured using a rotating Scheimpflug camera (Pentacam) and partial coherence interferometry (IOLMaster) in the high myopia group and the control group. RESULTS: The study comprised 287 patients (520 eyes). There were 194 eyes in the high myopia group and 326 eyes in the control group. The 5 anterior corneal aberrations-vertical coma, vertical trefoil, horizontal coma, oblique trefoil, and primary spherical aberration-in the high myopia group were 0.07 MUm +/- 0.38 (SD), -0.11 +/- 0.23 MUm, 0.07 +/- 0.28 MUm, -0.02 +/- 0.18 MUm, and 0.39 +/- 0.19 MUm, respectively. No negative primary spherical aberrations of the total or anterior corneal surface were found in the high myopia group. Differences between the 2 groups were found in terms of central corneal thickness, astigmatism, primary spherical aberration, vertical coma, and oblique trefoil; however, these differences were not consistent between different age subgroups. Higher-order aberrations were correlated with age. Posterior corneal vertical coma was correlated with AL (Pearson correlation = -0.188, P = .047). CONCLUSIONS: Negative primary spherical aberrations of the anterior or total corneal surface were not found in the high myopia group. Age showed a strong relationship with HOAs. For cataract patients with high myopia, aspheric intraocular lens implantation is recommended.

AB - PURPOSE: To determine the effect of Visian Implantable Collamer Lens phakic intraocular lens (pIOL) insertion on biometric parameters and IOL power calculation. SETTING: Beirut Eye and ENT Specialist Hospital, Beirut, Lebanon. DESIGN: Prospective case series. METHODS: The IOLMaster 500 biometer was used to measure axial length (AL), keratometry (K), and anterior chamber depth (ACD) values before and 2 months after pIOL implantation. The IOL power was calculated using third-generation formulas (SRK/T, Holladay 1, Hoffer Q) and fourth generation formulas (Haigis, Barrett Universal II). RESULTS: The study comprised 24 eyes (12 patients). The preoperative and postoperative AL were comparable (27.35 mm +/- 1.51 [SD] versus 27.36 +/- 1.6 mm; P = .91), as were the K values. There was a significant difference between the preoperative and postoperative ACD (3.67 +/- 0.46 mm versus 3.4 +/- 0.56 mm; P = .008). The mean IOL power calculation did not change significantly using the Haigis (10.04 +/- 3.42 diopters [D] versus 10.1 +/- 3.59 D; P = .69), SRK/T (9.85 +/- 3.41 D versus 9.94 +/- 3.58 D; P = .44), Holladay 1 (9.70 +/- 3.47 D versus 9.80 +/- 3.64 D; P = .45), Hoffer Q (9.70 +/- 3.40 D versus 9.85 +/- 3.59 D; P = .37), or Barrett Universal II (9.29 +/- 3.52 D versus 9.35 +/- 3.71 D; P = .63) formula. CONCLUSIONS: Phakic IOL insertion did not affect IOL power calculation. If preoperative data are not available, postoperative values can be used in IOL calculation formulas. PMID- 30274845 TI - Expression levels of aldose reductase enzyme, vascular endothelial growth factor, and intercellular adhesion molecule-1 in the anterior lens capsule of diabetic cataract patients. AB - PURPOSE: To compare the levels of aldose reductase (ALR) enzyme, intercellular adhesion molecule-1 (ICAM-1), and vascular endothelial growth factor (VEGF) in the anterior lens capsule of diabetic versus nondiabetic patients. SETTING: Alexandria Main University Hospital, Alexandria, Egypt. DESIGN: Prospective case control study. METHODS: The study enrolled patients undergoing cataract extraction and divided them into 3 groups: eyes that had proliferative diabetic retinopathy (PDR), eyes that had nonproliferative diabetic retinopathy (NPDR), and nondiabetic eyes. The anterior lens capsules were obtained by performing femtosecond laser-assisted capsulorhexis. Concentrations of ALR, ICAM-1, and VEGF in the lens capsule specimens were measured using human enzyme-linked immunosorbent assay. RESULTS: This study comprised 200 patients (200 eyes); 51 eyes had PDR, 49 eyes had NPDR, and 100 eyes were nondiabetic. The mean ALR, ICAM 1, and VEGF levels in the anterior capsule of diabetic group were 2.84 nanogram (ng)/mL +/- 0.51 (SD), 87.73 +/- 22.84 picogram (pg)/mL, and 75.53 +/- 14.95 pg/mL, respectively; whereas, in the nondiabetic group, they were 1.44 +/- 0.17 ng/mL, 35.45 +/- 2.8 pg/mL, and 33.55 +/- 5.47 pg/mL, respectively. In comparing the concentrations of these mediators, both the PDR and NPDR groups had significantly higher levels compared with the nondiabetic eyes (P < .001). In addition, eyes with PDR had significantly higher levels of these mediators than eyes with NPDR (P < .001). CONCLUSION: The concentrations of ALR, ICAM-1, and VEGF in the anterior lens capsule of diabetic patients are significantly higher than those of nondiabetics. A significantly higher level of 3 mediators in eyes with PDR compared with those with NPDR might allow the use of them as a biomarker for severity of diabetic retinopathy.

PMID- 30274848 TI - Efficiency of video-presented information about excimer laser treatment on ametropic patients' knowledge and satisfaction with the informed consent process. AB - PURPOSE: To evaluate whether the presentation of a video within the informed consent consultation affects patient knowledge about refractive excimer laser treatment, satisfaction with the informed consent process, anxiety in respect to the planned surgery, and the consultation duration. SETTING: Tertiary referral center, Lucerne, Switzerland. DESIGN: Single-center, randomized controlled trial. METHODS: Consenting eligible patients were randomly assigned to receive either a conventional face-to-face consultation (conventional group) or a conventional consultation with additional video-assisted information (interventional group). Knowledge and satisfaction with the informed consent process and anxiety regarding surgery were assessed. Differences between groups were tested with Wilcoxon-Mann-Whitney, Chi-square, and Student t tests. RESULTS: The study comprised 113 patients (58 in the conventional group and 55 in the interventional group). There was no difference in terms of knowledge with 22/25 points (interquartile range [IQR], 3) in the conventional group versus 22/25 points (IQR, 2) in the interventional group (P = .957), satisfaction with the informed consent ("very satisfied": 47/58 versus 45/55; P = .915) and anxiety toward surgery with a median 8 (IQR, 4) versus median 9 (IQR, 3; P = .159). In the interventional group, however, the total consultation time was significantly lower than in the conventional group (-4.96 minutes; 95% CI, -9.50 to -0.43; P = .032). CONCLUSION: Compared with a conventional consultation, video-assistance slightly reduced the total consultation time while maintaining patient knowledge, satisfaction with the informed consent process, and anxiety regarding the surgery on equal levels. Video-assistance could increase efficiency of clinical management on a double-digit percentage at an equal running cost compared with a conventional consultation.

AB - Platelet-rich plasma (PRP) is a preparation for therapeutic purposes that is increasingly accepted for various musculoskeletal disorders, due to its theoretical potential to repair tissues with poor healing capacity. Several randomised clinical trials have investigated the capacity of PRP to repair tendons, ligaments, muscles and cartilage, and to date there is level 1a evidence to support its use for lateral epicondylitis, osteoarthritis of the knee, plantar fasciitis and rotator cuff tendinopathy; and level 1b for patellar tendinopathy and osteoarthritis of the hip. Retrospective cohort studies and case series describe promising results with PRP for treating other musculoskeletal disorders. Since its side effects are fewer than those of the control groups, the treatment is considered practically harmless and is being increasingly used. Further randomised clinical trials are necessary to establish future indications, and to confirm effectiveness and safety. PMID- 30274851 TI - Self Limiting Sternal Tumors of Childhood: Two Case Reports. AB - Sternal tumours are rare in children. The differential diagnoses include a wide spectrum of benign (from bone cyst to osteoblastoma, osteochondroma and fibrous displasia) and malignant tumours (Ewing's sarcoma, chondrosarcoma rhabdomyosarcoma), inflammatory lesions and infectious processes. The SELSTOC (Self Limiting Sternal Tumours of Childhood) are entities of non-specific origin, they are self-limiting and characterised by a rapidly growing tumour that disappears spontaneously with no history of trauma or active infection. The onset of a rapidly growing mass with no preceding trauma is worrying to parents who then consult the health professionals. Soft tissue ultrasound enables us to characterise these lesions and define their nature in relation to the adjacent tissues. Chest x-ray and MRI can also help to characterise these lesions. In this paper we present two case reports of children referred to our department for characterisation of sternal tumours. PMID- 30274852 TI - Compulsory community treatment and ethnicity: Findings from a culturally and linguistically diverse area of Queensland. AB - OBJECTIVE: To compare the use of community treatment orders (CTOs) and forensic orders (FOs) in a culturally and linguistically diverse (CALD) population to that in a non-CALD population. METHODS: We analysed the relationship between coming from a CALD background and the use of CTOs and FOs on discharge from hospital using merged data from the Metro South Addiction and Mental Health Service's Transitions of Care (ToC) and Consumer Integrated Mental Health Application (CIMHA) databases. RESULTS: Nine hundred and seventy-six individual records were included in the data set, of whom eighty-six were from a CALD background (8.8%). Three hundred and eleven patients were on compulsory community treatment. Use of compulsory community treatment (CTOs and FOs) was similar for those born in Australasia, British Isles, North America and Europe but significantly higher for those born elsewhere even after adjusting for socio-demographic and clinical variables (Adj OR 2.19, 95% CI 1.36-3.52). The use of an interpreter significantly increased the likelihood of compulsory community treatment (Adj OR 2.76, 95% CI 1.20-6.35). Restricting the analyses to CTOs only did not alter these results. CONCLUSIONS: Metro South residents from a CALD background outside of Europe were over-represented on compulsory community treatment orders. This could reflect the difficulties in accessing voluntary services, communication barriers, stigma associated with mental illness, discrimination, or issues related to accurately diagnosing mental illness cross-culturally. Clinicians need to be aware of the complexity of working with people from diverse cultures and apply these orders judiciously. PMID- 30274853 TI - Phage assembly and the special role of the portal protein. AB - Virus infections are ultimately dependent on a successful viral genome delivery to the host cell. The bacteriophage family Caudovirales evolved specialized machinery that fulfills this function: the portal proteins complex. The complexes are arranged as dodecameric rings and are a structural part of capsids incorporated at a five-fold vertex. They are involved in crucial aspects of viral replication, such as virion assembly, DNA packaging and DNA delivery. This review focuses on the organization and the mechanism through which these portal complexes achieve viral genome delivery and their similarities to other viral portal complexes. PMID- 30274854 TI - Distributed point source modeling of the scattering of elastic waves by a circular cavity in an anisotropic half-space. AB - The Distributed Point Source Method (DPSM) is a modeling technique based on superposition of fundamental solutions corresponding to individual pair of source and target points. A collection of source points distributed over the boundaries and interfaces are responsible for transmission, reflection, and refraction of acoustic waves in the solution domain. The strength of the source points may not be known a priory. By imposing the prescribed conditions on the boundaries and interfaces, a system of equations with the source strengths as the unknowns is obtained. After finding the source strengths as the solution to this system of equation, the amount of the solution at any target point in the domain is obtained by superimposing the effect of all source points on that target point. DPSM is an efficient modeling technique for ultrasonic problems since it does not require discretization of the whole solution domain but only the boundaries and interfaces. The fundamental solution, or the Green's function, between a pair of source and target points serves as the building block for DPSM. For an ideal fluid or a homogeneous isotropic solid the elastodynamic Green's function is available as closed form algebraic expressions. But for an anisotropic solids, the set of governing equations are considerably more complex and the elastodynamic Green's function needs to be evaluated numerically. In this study, an anisotropic half-space containing a flaw in the form of a circular hole is considered. The solid half-space is in contact with fluid and a transducer is located in fluid facing the solid half-space. Some efforts have been made to alleviate the computational intensity of the numerical evaluation of anisotropic Green's function for this problem. Firstly, a technique called "windowing" is used to exploit the repetitive pattern of relative positions of the source and target points in order to considerably reduce the number of Green's function evaluations. Secondly, the resolution of the integration for evaluation of the anisotropic Green's function is changed based on the distance between the source and target points, and a calibration technique based on an equivalent isotropic stiffness tensor is suggested. This calibrated multi-resolution integration technique is combined with the windowing technique, and the developed DPSM model is applied to a numerical example containing a transversely isotropic half-space, to show the applicability and effectiveness of DPSM modeling for this class of problems. Important applications like non-destructive evaluation of composite materials may benefit from such modeling capability.

PMID- 30274856 TI - Albumin-Bilirubin Score: An Accurate Predictor of Hepatic Decompensation in High Risk Patients Undergoing Transarterial Chemoembolization for Hepatocellular Carcinoma. AB - PURPOSE: To evaluate validity of albumin-bilirubin (ALBI) grade as a predictor of acute-on-chronic liver failure (ACLF) after transarterial chemoembolization for hepatocellular carcinoma (HCC) in patients with baseline moderate to severe liver dysfunction. MATERIALS AND METHODS: In this retrospective study, serum albumin and bilirubin levels measured before chemoembolization were used to calculate ALBI score in 123 patients treated with 187 high-risk chemoembolizations. Procedures were considered high risk if Child-Turcotte-Pugh score before chemoembolization was >= 8. ACLF was objectively measured using chronic liver failure-sequential organ failure assessment score at 30 and 90 d. The 30-day mortality and morbidity from new or worsening ascites and/or hepatic encephalopathy (HE) were assessed. Univariate and multivariate analyses were used to identify clinical and procedural predictors of ACLF in this high-risk population. RESULTS: ACLF occurred after 15 (8%) high-risk chemoembolizations within 30 days and an additional 9 (5%) procedures between 30 and 90 days. Overall 30-day mortality was 2.7%. New or worsened ascites and/or HE occurred after 52 (28%) procedures within 30 days. Significant prognosticators of ACLF at 90 days revealed by univariate analysis were bilirubin (P = .004), albumin (P = .007), and ALBI score (P = .002), with ALBI score remaining statistically significant on multivariate regression analysis (OR = 3.99; 95% CI, 1.70-9.40; P = .002). CONCLUSIONS: Chemoembolization for HCC can be performed safely in patients with moderate to severe liver dysfunction. ALBI score before chemoembolization provides objective prognostication for ACLF after chemoembolization in this cohort and may be used for risk stratification.

AB - A two-dimensional model for solute migration, transformation, and deposition in a phreatic solution conduit penetrating a karst aquifer is presented in which the solute is anthropogenic to the natural system. Transformation of a reacting solute in a solution conduit has generally been accepted as likely occurring but actual physical measurements and mathematical analyses of the suspected process have been generally minimally investigated, primarily because of the logistical difficulties and complexities associated with solute transport through solution conduits. The model demonstrates how a reacting solute might decay or be transformed to a product solute some of which then migrates via radial dispersion to the conduit wall where it may become adsorbed. Model effects vary for laminar flow and turbulent flow in the axial direction. Dispersion in the radial direction also exhibits marked differences for both laminar flow and turbulent flow. Reaction zones may enhance subsequent reactions due to some overlap resulting from the longitudinal dispersion caused by flow in the axial direction. Simulations showed that varying the reaction rate coefficient strongly affects solute reactions, but that varying deposition coefficients had only minimal impacts. The model was applied to a well-known tracer test that used the tracer dye, Rhodamine WT, which readily converts to deaminoalkylated Rhodamine WT after release, to illustrate how the model may be used to suggest one possible cause, in addition to other possible causes, for less than 100 tracer-mass recovery. In terms of pollutants in a karst aquifer the model also suggests one possible mechanism for pollutant transformation in a solution conduit. PMID- 30274864 TI - ? PMID- 30274866 TI - Editorial.

AB - BACKGROUND: Most studies on immunocastration currently focused on male animals. However, immunization of male animals does not completely inhibit sexual behavior and fertility. This study aimed to compare the immunocastration effect of KISS1 DNA vaccines encoding different lengths of kisspeptins in female rats for effective castration effects on both male and female rats. METHODS: Fifteen female rats were randomly divided into three groups. The rats in T1 group or T2 group was orally given respectively KISS1-54 or KISS1-10 DNA vaccines with fused tPA signal peptide, and the control group (Group C) was orally administered with empty vector vaccine, at a dose of 5 * 109 CFU/rat at weeks 0, 3 and 6 of the study. Blood samples were collected by retroorbital bleeding before primary immunization and at weeks 3 and 9 after primary immunization. RESULTS: Both KISS1 54 and KISS1-10 DNA vaccines induced the body's humoral immune response, and the anti-kisspeptin antibody titres in the T1 group were significantly higher than that in T2 and C groups (p < 0.05). The rats in T1 group has lower serum kisspeptin and estradiol levels than those in T2 and C groups and smaller litter size of rats than those in the control group after mating (p < 0.05). No significant difference was observed between T2 and C groups. The levels of KISS1 and GPR54 mRNA in the hypothalamus and ovaries of the T1 group were significantly lower than that in control group. However, the levels of KISS1 mRNA in the T2 group were significantly lower than that in the control group only in ovaries (p < 0.05). CONCLUSION: The oral KISS1-54 DNA vaccine with fused tPA signal peptide was more effective than that KISS1-10 DNA vaccine in suppressing fertility of female rats. PMID- 30274869 TI - Shared reality: Construct and mechanisms. AB - To provide background for the Special Issue on shared reality, we outline the construct of shared reality and underlying mechanisms. Shared reality is the experience of having in common with others inner states about the world. Inner states include the perceived relevance of something, as well as feelings, beliefs, or evaluations of something. The experience of having such inner states in common with others fosters the perceived truth of those inner states. Humans are profoundly motivated to create shared realities with others, and in so doing they fulfill their needs to have valid beliefs about the world and to connect with others.

AB - The objective of this study was to evaluate effects of whole body radiation exposure early in life on influenza vaccination immune responses much later in life. A total of 292 volunteers recruited from the cohort members of ongoing Adult Health Study (AHS) of Japanese atomic bomb (A-bomb) survivors completed this observational study spanning two influenza seasons (2011-2012 and 2012 2013). Peripheral blood samples were collected prior to and three weeks after vaccination. Serum hemagglutination inhibition (HAI) antibody titers were measured as well as concentrations of 25 cytokines and chemokines in culture supernatant from peripheral blood mononuclear cells, with and without in vitro stimulation with influenza vaccine. We found that influenza vaccination modestly enhanced serum HAI titers in this unique cohort of elderly subjects, with seroprotection ranging from 18 to 48% for specific antigen/season combinations. Twelve percent of subjects were seroprotected against all three vaccine antigens post-vaccination. Males were generally more likely to be seroprotected for one or more antigens post-vaccination, with no differences in vaccine responses based on age at vaccination or radiation exposure in early life. These results show that early life exposure to ionizing radiation does not prevent responses of elderly A bomb survivors to seasonal influenza vaccine. PMID- 30274871 TI - Introduction. PMID- 30274872 TI - A Pathway to Publishing an Oncology Nursing Book. AB - OBJECTIVES: To describe the process of book publishing, including authoring and revising book chapters, and provide resources on book publishing opportunities for oncology nurses. DATA SOURCES: Journal articles, book publishers' information for authors, online publishing resources, discussions with textbook editors, personal experience. CONCLUSION: Few published resources exist to guide nurses as they author and/or revise books and book chapters. In addition, book publishing presents unique considerations, such as authorship of subsequent editions, and new opportunities, such as self-publishing and electronic textbook formats. IMPLICATIONS FOR NURSING PRACTICE: Textbooks are enduring repositories of comprehensive information used by both students and clinicians. Oncology nurses have expert research and clinical expertise that can contribute to this body of published nursing knowledge and ultimately improve the care of people with cancer. PMID- 30274874 TI - Retrospective dosimetric analysis of brain lesions planned in Pinnacle 9.8 via a HDMLC linac. AB - The University of Toledo Medical Center's Eleanor N. Dana Cancer Center located in northwest Ohio currently utilizes the Edge Radiosurgery System (Varian Medical Systems Inc., Palo Alto, CA) to deliver stereotactic radiosurgery for the treatment of brain lesions. The purpose of this study is to determine the quality of conformal arc radiotherapy in treating patients with brain lesions at The University of Toledo Medical Center and to provide more data for conformity and gradient indices (due to a lack of current data) to hopefully improve national standards by allowing centers to compare among each other. Treatment plans were assessed using the Pinnacle3 v9.8 Radiation Therapy Planning System (Philips Healthcare, Amsterdam, Netherlands). For patients (n = 41) presenting with small brain lesions (n = 82) and treated with conformal arc radiotherapy via the Edge Radiosurgery System, the RTOG conformity index, Paddick conformity index, conformity gradient index, gradient index, and dose gradient index were determined for each plan. This study additionally provides data to suggest the more accurate method of volume derivation provided by the Pinnacle3 v9.8 software. Using this method, average values for each of the following indices were calculated: RTOG conformity index = 1.36 +/- 0.29; Paddick conformity index = 0.72 +/- 0.12; conformity gradient index = 214.67 +/- 12.35; gradient index = 3.64 +/- 1.09; dose gradient index = -0.11 +/- 0.16. Thus, The University of Toledo Medical Center provides favorable conformity of dose to intracranial target lesions. PMID- 30274873 TI - A Population-Based Study of Intracerebral Hemorrhage Survivors' Outcomes. AB - BACKGROUND: We evaluated 3-month neurologic, functional, cognitive, and quality of life (QOL) outcomes in intracerebral hemorrhage (ICH) overall, and by sex and ethnicity in a population-based study. METHODS: Spontaneous ICH patients were identified from the Brain Attack Surveillance in Corpus Christi project (November 2008 to December 2013). Outcomes included neurologic (National Institutes of Health Stroke Scale: range 0-42), functional (activities of daily living/instrumental activities of daily living score: range 1-4, higher worse), cognitive (Modified Mini-Mental State Examination [3MSE]: range 0-100), and QOL (short-form stroke-specific QOL scale: range 0-5, higher better). Ethnic and sex differences were assessed with Tobit regression adjusted for age, sex, or ethnicity, and presenting Glasgow coma scale. RESULTS: A total of 245 patients completed baseline interviews, with 103 (42%) dying prior to follow-up, leaving 142 eligible for outcome assessment. Three-month follow-up was completed in 100 (neurologic), 107 (functional), 79 (cognitive), and 83 (QOL) participants. Median age was 66 years (interquartile range 58.0-77.0). Cognitive outcomes were worse in Mexican Americans (MA) compared to non-Hispanic whites (NHW) after multivariable adjustment (MA scoring 13.3 3MSE points lower than NHW [95% confidence interval: 5.8, 20.7; P = .0005]). There was no difference by sex or ethnicity in neurological, functional, or QOL outcomes, and no sex differences in cognitive outcomes. CONCLUSIONS: In this population-based study, worse cognitive outcomes were found in MAs compared with NHW. There were no differences between neurologic, functional, and QOL outcomes in ICH survivors based on sex or ethnicity.

PMID- 30274876 TI - Low back pain intensity among childbearing women and associated predictors. A cohort study. AB - BACKGROUND: Low back pain is a common condition among childbearing women, causing physical disability and an increased risk of sick leave and obstetric complications. AIMS: To assess the prevalence and intensity of low back pain during pregnancy, to describe the physical disability and sick leave in relation to the severity of low back pain and to identify predictors of moderate to severe low back pain in socio-demographic, health and obstetric characteristics among childbearing women. METHODS: A cohort study was undertaken (n=566) during August 2015 to March 2016. Questionnaires were used to obtain information about low back pain intensity, physical disability due to low back pain and sick leave at 20 and 32weeks of gestation. Of the 654 eligible women, 87% completed the first questionnaire. FINDINGS: Three out of four reported any low back pain at 20weeks of gestation, and nine out of ten women at 32weeks. Of these women, one in three reported moderate to severe pain at 20weeks, increasing to half of the women at 32weeks. Both sick leave and physical disability increased with increasing low back pain scores. Pre-pregnancy low back pain, multiparity and lower level of education were all identified as predictors of moderate to severe low back pain. CONCLUSIONS: Women with pre-pregnancy low back pain, multiparity and lower level of education, represent the group of women with the highest risk of moderate to severe low back pain during pregnancy and should be payed special attention. PMID- 30274877 TI - Previous breastfeeding experience and its influence on breastfeeding outcomes in subsequent births: A systematic review. AB - PROBLEM: Despite widely recognized benefits of breastfeeding, the worldwide rate of six months exclusive breastfeeding has not up to the WHO recommendation. Multiparas are considered more likely to initiate breastfeeding and breastfeed much longer. This, however, is not always the case if they have unsuccessful previous breastfeeding experience. Therefore, whether and how previous breastfeeding experience affect subsequent breastfeeding outcomes need to be explored sufficiently. OBJECTIVE: The objective of this review is to summarize the evidence of association between previous breastfeeding experience and subsequent breastfeeding outcomes. METHODS: A systematic search of Embase, Web of Science, PubMed, Cochrane Library and CINAHL databases from inception to March, 2018 is conducted for cohort studies regarding "previous breastfeeding experience" as an influencing factor to subsequent breastfeeding initiation and duration. A narrative synthesis is used in this review according to PRISMA and study quality is assessed using the Newcastle-Ottawa Scale. FINDINGS: Fifteen articles were eligible for this review. Previous breastfeeding experience was consistently correlated with subsequent breastfeeding initiation and duration. However, previous short breastfeeding duration and unsatisfactory experience negatively affected subsequent breastfeeding. CONCLUSIONS: Robust evidence for the effect of previous breastfeeding experience on subsequent breastfeeding is present. Midwives and breastfeeding/lactation consultants need to provide customized interventions for mothers according to detailed previous breastfeeding experience in order to improve breastfeeding initiation and breastfeeding duration. PMID- 30274878 TI - The relationship between maternal weight gain in pregnancy and newborn weight. AB - AIM: This study investigated the impacts of different pre-pregnancy body mass indexes and gestational weight gain on the risk of delivering a high birth weight infant in China. METHODS: A retrospective cohort study was conducted from 2013 to 2014 in the Maternal and Child Health Care Hospital of Jinan City, Shandong Province and 2415 women who had a singleton birth were included in the study. A logistic regression model and restricted cubic spline regression were used to analyse the association. FINDINGS: The risk of delivering a high birth weight infant increases when the mother's pre-pregnancy body mass index exceeds 24kg/m2. Compared with women whose pre-pregnancy body mass index was 21kg/m2, the adjusted risk of delivering a high birth weight infant doubled when the mother's pre pregnancy body mass index was 29kg/m2, and nearly tripled when the mother's pre pregnancy body mass index was 31kg/m2. Compared with women who had a gestational weight gain of 12.0kg, women having a gestational weight gain of 20.0kg, 22.0kg, and 26.0kg had a 1.7-, 2.2-, and 3.5-fold increased risk of delivering a high birth weight infant. When the mother experiences a gestational weight gain greater than 27kg, the risk of delivering a high birth weight infant is at least 4-fold greater than that for a mother who has a gestational weight gain of 12.0kg. CONCLUSIONS: Proposed strategies to raise public awareness of the risks to infants posed by high maternal pre-pregnancy body mass index and gestational weight gain are required. All clinical recommendations and measures are for all pregnant women, not just overweight and obese pregnant women. PMID- 30274879 TI - The association between social support and postpartum depression in women: A cross sectional study. AB - BACKGROUND: Prevalence of postpartum depression is estimated to be about 10-15% worldwide. Many risk factors are supposed to play a role leading a new mother to maternal postpartum depression which can considerably affect the baby, mother, family and also the society. OBJECTIVE: To investigate the prevalence of maternal postpartum depression and its association with social support. METHODS: Using a cross-sectional study, 200 new mothers who attended three teaching hospitals in Tehran, Iran were selected with a convenience sampling. Postpartum depression was assessed using the Iranian version of Edinburgh Postpartum Depression Scale and women's levels of social support were measured using the Iranian version of Social Support Questionnaire. RESULTS: Prevalence of postpartum depression was 43.5% in new mothers. The mean (+/-Standard Deviation) score of social support network was 2.09+/-0.99; which is lower in depressed mothers in comparison to non depressed mothers (1.78+/-0.87 vs. 2.33+/-1.00 respectively, P<0.001). A reverse significant association was found between social support and postpartum depression after adjusting for confounding variables such as past history of depression, illness of baby and medication consumption during pregnancy (Odds Ratio=0.47, 95% Confidence Interval=0.33-0.67). CONCLUSION: The bigger the social network of a mother, the less postpartum depression occurs. It is suggested to educate the family about the very important role of social support and improve it in every aspect of health care in order to prevent postpartum depression. PMID- 30274880 TI - Adaptation of Proximal Femur to Mechanical Loading in Young Adults: Standard Vs Localized Regions Evaluated by DXA. AB - Regions of the proximal femur with less adaptive protection by mechanical loading may be at increased risk of structural failure. Since the size and location of these regions diverge from those defined by the dual-energy X-ray absorptiometry manufacturers the purpose of this study was to compare areal bone mineral density (aBMD) of different regions of the proximal femur considering impact loads from physical activity (PA). The participants were 134 young adults divided into 2 groups according to the impact of PA performed in the last 12 mo: high-impact PA and low-impact PA. The aBMD of the proximal femur was assessed by dual-energy X ray absorptiometry at the standard femoral neck, intertrochanter, and trochanter, and at specific locations of the superolateral femoral neck and intertrochanteric region. The bone-specific physical activity questionnaire was used to estimate the impact load of PA. Comparisons between groups were adjusted for body height and body lean mass. Interaction analysis between sex and PA groups were conducted with analysis of variance. Comparisons of aBMD between bone regions were analyzed separately for men and women with repeated measures analysis of variance. In the high-impact PA group, men benefit more than women at all bone regions, except the aBMD at intertrochanteric region. Analyses of repeated measures did not reveal any significant interaction effect between bone regions (standard vs specific) and PA groups (low vs high-impact). In conclusion, aBMD differences due to mechanical loading were more pronounced in men than in women; the magnitude of the aBMD differences as a result of different levels of PA was similar between standard and localized regions. PMID- 30274881 TI - Is recurrent pyogenic cholangitis an independent poor prognostic indicator for resectable intrahepatic cholangiocarcinoma? PMID- 30274882 TI - Surgical resection of lymph node positive intrahepatic cholangiocarcinoma may not improve survival. AB - BACKGROUND: Nodal positivity is a predictor of poor survival following resection for intrahepatic cholangiocarcinoma (ICC). The aim of this study was to evaluate the impact of surgical resection on survival in patients with lymph node (LN) positive ICC. METHODS: An augmented version of the Surveillance, Epidemiology, and End Results program database was utilized to identify patients with LN positive ICC without distant metastases from 2000 to 2014. Patients were stratified by treatment: chemotherapy alone or surgical resection with/without chemotherapy. Survival was evaluated using Kaplan-Meier and Cox proportional hazard models. RESULTS: 169 patients who underwent treatment for LN-positive ICC were identified. 88% underwent surgical resection and 12% underwent chemotherapy alone. The median survival for patients who underwent surgical resection was not different from patients treated with chemotherapy alone (19 months 95% Confidence Interval (CI) 17-33 versus 20 months CI 10-27, p = 0.323). A cox-proportional hazard ratio model demonstrated that black race was associated with worse survival (p < 0.05), while surgical resection was not independently associated with survival. CONCLUSION: Surgical resection for patients with LN-positive ICC may not improve survival compared to chemotherapy alone. Pathologic LN evaluation should be performed prior to surgical resection, to improve patient selection and ensure receipt of optimal therapy. PMID- 30274883 TI - Management of pregnancy-associated pancreatic cystic tumors: Review of the literature and results of a Pancreas Club Inc. Survey. AB - BACKGROUND/OBJECTIVES: Management of patients with pregnancy-associated cyst pancreatic cystic tumors (PA-PCT) is complicated by lack of large series. METHODS: A systematic literature review was conducted to extrapolate data on management of PA-PCT, and make a questionnaire on pending issues to be administered to the members of the Pancreas Club Inc. RESULTS: The literature review demonstrated a total of 35 PA-PCT in 34 women, described exclusively in the form of case reports, and permitted the identification of eleven key questions to be addressed in the survey. The combined analysis of literature review and survery responses provided several information. First, PA-PCT are predominantly located in the body-tail of the pancreas, cause non-specific symptoms, are of large size (mean size: 11.2 +/- 4.5 cm), and are nearly always malignant or premalignant, making timing of surgery, and not indication for surgery, the main issue in the management of these tumors. Second, there is a risk of PA-PCT rupture during pregnancy. Ruptured PA-PCT had a mean size 13.5 +/- 4.9 cm, but no prognostic factor could be identified. Survey opinions suggested that this occurrence is quite rare, even for large tumors. Third, most pregnancies were conducted to term (mean gestational age: 40.5 +/- 0.7 weeks), with a vaginal delivery. Fourth, all procedures were carried out through an open approach and the spleen was rarely preserved. Survey indicated instead that laparoscopy could play a role, and that the spleen should be preserved when feasible. CONCLUSIONS: PA-PCT require individualized treatment. The definition of a management algorithm requires the implementation of an International Registry. PMID- 30274884 TI - Pharmacist perceptions of the New Mexico pharmacist-performed tuberculosis testing program. AB - OBJECTIVE: This study evaluated pharmacists' perceptions of the New Mexico pharmacist-performed tuberculosis skin testing (PPTST) program. METHODS: This cross-sectional study was conducted using a telephone survey. New Mexico pharmacists who completed the tuberculin skin test (TST) training from March 2011 to June 2016 were eligible for inclusion. Data collected included demographics, years since licensure, pharmacy setting and location, reasons for obtaining certification, training time, training quality, self-perceived competency after training, whether the participant was performing TSTs, number of tests performed, time required to administer or interpret the test, and reasons for not testing. RESULTS: We attempted to contact all 209 pharmacists who completed the TST training during the evaluation period. Ninety-four of the 99 pharmacists contacted consented to participate (overall study response rate of 45%). The chain community pharmacy was the most common practice setting of respondents. After training completion, greater than 95% agreed or strongly agreed they felt confident in administering the TST. The percent of respondents working in New Mexico who were actively testing was 50.6%, with 42% of those pharmacists providing TSTs in small cities. Eleven pharmacists reported that they were performing TSTs in locations where testing would not otherwise have been available. An initial TST visit was approximately 6-15 minutes, and follow-up visits were typically 5 minutes or less. The most common reason reported for not testing was lack of employer support (61%). The strongest association with testing was training requirement by employer (odds ratio [OR], 20.4; 95% CI 4.2 99.2), followed by strong confidence in their ability to perform the TST (OR, 14.2; 95% CI 2.8-71.2). CONCLUSION: PPTST is positively perceived by New Mexico pharmacists and provides testing in non-urban areas where access may be low. Survey respondents were confident in their ability to perform the TST and report that testing typically takes less than 15 minutes. The main hindrance to implementing PPTST was lack of employer support. PMID- 30274885 TI - Surgical site infection surveillance for elective primary total hip and knee arthroplasty in Winnipeg, Manitoba, Canada. AB - BACKGROUND: Surgical site infections (SSIs) increase morbidity and mortality after primary hip and knee arthroplasty. We evaluated a surveillance program that tracked risk factors associated with infection after primary hip and knee arthroplasty in the Winnipeg Regional Health Authority. METHODS: Surveillance data from April 2010 to March 2015 were reviewed for all 12,636 primary hip or knee arthroplasties, including 1-year follow-up. Procedures were evaluated in earlier (April 2010 to December 2012) and later periods (January 2013 to March 2015). Risk factors for postoperative infection were evaluated. RESULTS: There were 154 SSIs in 12,636 operations (1.22%) (earlier, 98 infections in 6,613 operations [1.48%]; later, 56 infections in 6,023 operations [0.93%]). The frequency of primary hip arthroplasty deep infection decreased from earlier to later periods; the frequency of primary knee arthroplasty infection was similar between the time periods. Independent risk factors associated with increased SSI risk included higher body mass index. SSI frequency was inversely associated with maintaining immediate postoperative temperature between 36 degrees C and 38 degrees C and surgery in the later period. CONCLUSIONS: Surveillance was effective in decreasing the frequency of deep infection after primary total hip arthroplasties but not after knee arthroplasties. Surveillance of orthopedic surgery with feedback of SSI rates to the front-line staff may result in improvement in surgical outcomes. PMID- 30274886 TI - The study of changes in raw meat salting using acoustically activated brine. AB - The article for the first time studies the kinetics of the activated brines diffusion inside meat based on the research of microstructure and nuclear magnetic resonance relaxation. The effect of ultrasound on the increase of hydration properties of pork proteins was found positive. The results of the experiments prove that spray penetration into not only interfibrillar spaces like during jetting but also inside muscle fibers leads to essential changes in meat structure, redistribution of brine components and acceleration of biochemical processes. PMID- 30274887 TI - Synergistic effect of sono-photocatalytic process for the degradation of organic pollutants using CuO-TiO2/rGO. AB - Combinations of different Advanced Oxidation Processes (AOPs) are being exploited for waste water treatment. The usage of ultrasound in photocatalysis finds much attention as the combined process offers some advantages over individual processes. Herein, we report the ultrasound assisted photocatalytic degradation of an organic pollutant (methyl orange as a model dye) in the presence of CuO TiO2/rGO photocatalyst which was prepared by a simple wet impregnation method. A synergistic effect (3.7-fold) was observed by combining the sonolysis and photocatalysis processes. Influence of Cu loading and graphene oxide (GO) dosage over the photocatalytic performance of TiO2 was examined in detail. The catalyst dosage and initial concentration of MO were optimized based on a series of experimental studies. Besides, neutral pH was found to show an optimum efficiency for this sono-photocatalytic process. PMID- 30274888 TI - Sonochemically recovered silver oxide nanoparticles from the wastewater of photo film processing units as an electrode material for supercapacitor and sensing of 2, 4, 6-trichlorophenol in agricultural soil samples. AB - The present work describes the sensing application and supercapacitive behavior of silver oxide nanoparticles recovered from wastewater of photo film processing units via one-pot green sonochemical recovery process. The recovered silver oxide nanoparticles (Ag2O NPs) were characterized by spectral techniques such as FT-IR, Raman, UV-Vis and analytical tools such as XRD, FE-SEM, TEM, EDX, XPS and BET. In view of Ag2O NPs as electrode material with wide technological applications, the recovered Ag2O NPs were examined for their sensing and supercapacitive behavior. The developed sensor was explored to detect 2, 4, 6-trichlorophenol, and as expected it shows moral parameters which are required of an effective sensor. Therefore, it was exploited for the quantification of 2, 4, 6-trichlorophenol in soil samples from the agricultural area. Cyclic voltammetric (CV), Galvanostatic Charge-Discharge (GCD) and Electrochemical Impedance Spectroscopic (EIS) studies on the recovered Ag2O NPs coated Ni foam electrode depicted the pronounced capacitive behavior. The GCD studies revealed an enhanced electrochemical performance, particularly with the large specific capacitance of 530 F/g at a current density of 1 A/g. The cyclic stability of the electrode material was identified with 88% retention in specific capacitance even after 5000 GCD cycles. These results strongly proved that the recovered Ag2O NPs are potential candidates for sensing and supercapacitor applications. PMID- 30274890 TI - Cavitation at filler metal/substrate interface during ultrasonic-assisted soldering. Part II: Cavitation erosion effect. AB - Using pure Sn as filler metal, this study investigated cavitation erosion effects during ultrasonic-assisted soldering. The physical process and mechanism of cavitation erosion were revealed. Superior erosion effects were observed under long ultrasonic times, small channel widths, and high ultrasonic powers. Different vibration intensities were obtained inside filler pool. Region I, which was located far from the sonotrode, exhibited a stronger vibration intensity and better erosion effect than those of the other regions. The erosion incubation stage was shorted than 0.5 s at the channel width of 0.2 mm. Complete oxide layer removal was obtained at an ultrasonic time of 2 s under this condition. The violent cavitation stage was shorter than the erosion incubation stage, and the removal of the oxide layer mainly depended on the stable cavitation stage. PMID- 30274889 TI - Combined effect of ultrasound treatment and exogenous phytohormones on the accumulation of bioactive compounds in broccoli florets. AB - Postharvest treatments such as wounding, ultrasound (US) and the exogenous application of ethylene (ET) and methyl jasmonate (MJ) have been studied as an effective tool to improve the content of secondary metabolites in fresh produce. The present study evaluated the immediate and late response (storage for 72 h at 15 degrees C) to US treatment (20 min, frequency 24 kHz, amplitude 100 MUm) alone and combined with exogenous MJ (250 ppm) and/or ET (1000 ppm) on glucosinolates, isothiocyanates, phenolic compounds and ascorbic acid content in broccoli florets. US treatment increased the extractability of glucosinolates [glucoraphanin (795%), 4-hydroxy glucobrassicin (153%), glucobrassicin (78.6%)] and phenolics [1-sinapoyl-2-feruloylgentiobiose (57.23%)] as compared with the control (CT). The combined application of MJ and US in broccoli florets, induced a synergistic effect on the accumulation of 4-hydroxy glucobrassicin (187.1%), glucoerucin (111.92%), gluconasturtiin (755.9%), neoglucobrassicin (232.8%), 3-O caffeoylquinic acid (73.4%), 1-sinapoyl-2-ferulolylgentiobiose (56.0%), and 1,2,2 trisinapoylgentiobiose (136.7%) at 72 h of storage. Interestingly, when the three stressors were applied together the synergistic effect of US + MJ observed on the accumulation of glucosinolates and phenolics was repressed. In general, the ascorbic acid content was not affected by US treatment and decreased in most samples during storage. However, when MJ + ET were applied, the content of total ascorbic acid was significantly reduced in CT + MJ + ET and US + MJ + ET samples after 72 h of storage by 53.4% and 86.6%, respectively, as compared with CT 0 h samples. Based on the results herein obtained, the application of US can be an effective tool to enhance the extractability of certain glucocosinolate and phenolic compounds in broccoli. Moreover, due to the synergistic effect observed on the accumulation of bioactive compounds, the combined application of US and MJ could be a practical approach to yield higher levels of glucosinolates and phenolic compounds in broccoli during storage. PMID- 30274891 TI - Investigations on sonofragmentation of hydroxyapatite crystals as a function of strontium incorporation. AB - Hydroxyapatite (Ca10(PO4)6(OH)2, HA) is chemically similar to the mineral component of bones and hard tissues in mammals. Various cations can substitute calcium in the crystal structure of hydroxyapatite. Among them strontium triggers interest, because strontium incorporated hydroxyapatite increases the number of bone forming sites in addition to having good biocompatibility. In the present investigation strontium substituted hydroxyapatite (SHA) in the compositions range 0, 10, 20, 50 and 100 mol% have been synthesized by precipitation method and subjected to ultrasonic treatment for different time intervals to gain insight on the role of ultrasound in modifying the morphology of SHA. This study reveals that the aspect ratio of SHA varied with the duration of ultrasonication. SHA samples subjected to 5 min ultrasound experienced an increase in aspect ratio. Further increase of ultrasonication time tends to decrease the aspect ratio invariably for all SHA samples indicating particle fragmentation. The extent of sonofragmentation as a function of percentage incorporation of strontium in HA lattice has been studied as a part of the present investigation. This study indicated that strain in the HA lattice has correlation with strontium incorporation, leading to varied extent of sonofragmentation. Also, the investigation suggested that 100% substitution of calcium sites by strontium leads to a relatively lesser strain and hence poor fragmentation. To the best of our knowledge the report on sonofragmentation of HA crystallites as a function of strontium incorporation is first of its kind in the literature. PMID- 30274892 TI - Ultrasonic assisted synthesis of magnetic Ni-Ag bimetallic nanoparticles supported on reduced graphene oxide for sonochemical simultaneous removal of sunset yellow and tartrazine dyes by response surface optimization: Application of derivative spectrophotometry. AB - The magnetic Ni-Ag bimetallic nanoparticles supported on reduced graphene oxide (Ni-Ag NPs/rGO) was synthesized and characterized by transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX), field emission scanning electron microscopy (FE-SEM) and vibrating sample magnetometer (VSM). Subsequently, this magnetic hybrid material as a novel adsorbent was applied for the sonochemical simultaneous removal of sunset yellow and tartrazine dyes in combination with first-order derivative spectrophotometric method to resolve the overlap between the spectra of these dyes. With magnetic properties, the adsorbent could easily be collected from aqueous solution using an external magnetic field. The parameters including initial concentration of each dye, adsorbent dosage and sonication time were studied by Box-Behnken design (BBD) and response surface methodology (RSM), while pH was studied by one-at-a-time approach. According to Box-Behnken design based on desirability function (DF), the best experimental conditions was set as initial sunset yellow concentration 10 mgL-1, initial tartrazine concentration 8.5 mgL-1, adsorbent dosage 0.045 g and sonication time of 15 min. The equilibrium data was fitted to different isotherm models and the results revealed the suitability of the Langmuir model. The maximum sorption capacity calculated from the Langmuir model was 28.57 and 26.31 mg g-1 for sunset yellow and tartrazine, respectively. Kinetic data revealed that the adsorption process followed a pseudo-second-order model. The reusability of the magnetite nanoparticles revealed about 8% decrease in the removal efficiency within four consecutive runs.

AB - BACKGROUND/PURPOSE: Nasal colonization of Staphylococcus aureus is a well-defined risk factor for subsequent infection. This study investigated the prevalence of methicillin-resistant S. aureus (MRSA) in southern Taiwan and aimed to identify the host factors for S. aureus colonization and the virulence factor of Panton Valentine Leukocidin (PVL) genes. METHODS: In a hospital-based study in Kaohsiung from Oct. 2005 to Dec. 2010, we performed nasal swab in the healthy children aged 2-60 months. We examined the relationship between the demographic characteristics and S. aureus nasal colonization. MRSA isolates were further analyzed for antimicrobial susceptibility and molecular characteristics. RESULTS: Among 3020 healthy children, 840 (27.8%) children had S. aureus nasal colonization. Of 840 isolates, 246 (29.3%) isolates were MRSA. MRSA colonization was significantly associated with age 2-6 months, day care attendance, and influenza vaccination. Breastfeeding was a protective factor against MRSA colonization. Most MRSA isolates were susceptible to trimethoprim-sulfamethoxazole and doxycycline. Ninety-four percent of MRSA isolates carried either type IV staphylococcal cassette chromosome mec (SCCmec) or SCCmec VT and 87% belonged to the local community strains, namely clonal complex 59/SCCmec IV or VT. MRSA isolates with PVL-negative was associated with children with passive smoking. CONCLUSIONS: Between 2005 and 2010, 27.8% and 8.14% of healthy children in southern Taiwan had nasal carriage of S. aureus and MRSA, respectively. Most MRSA isolates were local community strains. Several demographic factors associated with nasal MRSA colonization were identified.

AB - BACKGROUND: Clinical information of Elizabethkingia meningoseptica (EM) bacteremia in intensive care unit (ICU) patients is limited and the impact on outcomes uncertain. The aim of this study was to investigate the clinical features and impact of EM bacteremia compared to other glucose non-fermenting Gram-negative bacilli (GNF-GNB) bacteremia in ICU patients. METHODS: This retrospective cohort study enrolled 70 patients who developed GNF-GNB bacteremia after ICU admission, including 19 cases of EM bacteremia (19/70, 27.1%). The main outcome measure was in-hospital mortality. RESULTS: The patients with EM bacteremia had a lower rate of appropriate antibiotic therapy (15.8% vs. 62.7%, p < 0.001) and a longer time to appropriate antibiotic therapy (76.8 +/- 46.4 vs. 35.1 +/- 38.7 h, p < 0.001), but with a less severity in acute physiology and chronic health evaluation (APACHE) II score and shock status (p < 0.05) at the onset of bacteremia, compared to those with non-EM bacteremia. The in-hospital mortality between those with EM bacteremia and non-EM bacteremia was similar (63.2% vs. 51.0%, p = 0.363). However, primary bacteremia was more frequently noted in EM compared with non-EM group (57.9% vs. 25.5%, p = 0.011), and odds ratio 4.294 (95% confidence interval 1.292-14.277, p = 0.017) in multivariate regression analysis. CONCLUSION: Among the patients with GNF-GNB bacteremia, the numbers of the cases with primary bacteremia and inappropriate therapy were significantly more in EM group than those in non-EM group.

AB - BACKGROUND: Dengue is a rapidly emerging arthropod borne viral infection affecting tropical and sub-tropical regions of the world. Dengue is an acute febrile illness but sometimes causes more fatal complications like dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS). Delhi, the capital of India has become hyper endemic for dengue virus because all the four serotypes are circulating here. METHODS: The present study describes the identification of dengue virus from clinical samples collected from the suspected dengue patients from New Delhi, India during 2016. The CprM region of Dengue virus genome was analyzed for phylogenetic, selection pressure and Shannon entropy analyses. RESULTS: The present study reports circulation of a single serotype (DENV-3) in New Delhi, during 2016. The phylogenetic analysis revealed that Indian subcontinent (genotype III) of DENV-3 was circulating in Delhi during this period. Neutral selection pressure in the analyzed region revealed relatively conserved nature of this part of the Dengue virus genome. Amino acid at 31 was positively selected and had high entropy value suggesting probability of variation at this position. CONCLUSIONS: The changing trend in circulation of dengue virus serotypes necessitates the continuous epidemiological surveillance for the dengue outbreaks in this region.

PMID- 30274898 TI - High-protein diets for weight management: Interactions with the intestinal microbiota and consequences for gut health. A position paper by the my new gut study group. AB - BACKGROUND & AIMS: This review examines to what extent high-protein diets (HPD), which may favor body weight loss and improve metabolic outcomes in overweight and obese individuals, may also impact the gut environment, shaping the microbiota and the host-microbe (co)metabolic pathways and products, possibly affecting large intestine mucosa homeostasis. METHODS: PubMed-referenced publications were analyzed with an emphasis on dietary intervention studies involving human volunteers in order to clarify the beneficial vs. deleterious effects of HPD in terms of both metabolic and gut-related health parameters; taking into account the interactions with the gut microbiota. RESULTS: HPD generally decrease body weight and improve blood metabolic parameters, but also modify the fecal and urinary contents in various bacterial metabolites and co-metabolites. The effects of HPD on the intestinal microbiota composition appear rather heterogeneous depending on the type of dietary intervention. Recently, HPD consumption was shown to modify the expression of genes playing key roles in homeostatic processes in the rectal mucosa, without evidence of intestinal inflammation. Importantly, the effects of HPD on the gut were dependent on the protein source (i.e. from plant or animal sources), a result which should be considered for further investigations. CONCLUSION: Although HPD appear to be efficient for weight loss, the effects of HPD on microbiota-derived metabolites and gene expression in the gut raise new questions on the impact of HPD on the large intestine mucosa homeostasis leading the authors to recommend some caution regarding the utilization of HPD, notably in a recurrent and/or long-term ways. PMID- 30274899 TI - Proposed standard model and consistent terminology for monitoring and outcome evaluation in different dietetic care settings: Results from the EU-sponsored IMPECD project. AB - BACKGROUND & AIMS: Dietetic interventions contribute to certain health objectives and other outcomes, but are mostly part of a multimodal and multidisciplinary approach what makes evaluating the actual effects of dietitians' involvement rather complex. Although monitoring and outcome evaluation (M&OE) can provide routine data to prove the effectiveness of dietetic interventions, this has not been established yet in different dietetic settings. METHODS: A comprehensive framework for M&OE in dietetics was developed by dietetic experts from five European higher education institutes for dietetics in the course of the EU sponsored project "Improvement of Education and Competences in Dietetics (IMPECD)". RESULTS: Firstly, clear definitions on M&OE are proposed to facilitate the use of consistent terminology, with a specific emphasis on the term "impact" covering macro-level outcomes such as cost-effectiveness. Secondly, the Dietetic Care Process (DCP) was merged into a logic model to demonstrate the position of M&OE in relation to intervention planning and implementation, in both group and individual settings. Thirdly, selecting the appropriate indicators is indispensable to monitor and evaluate outcomes, and requires a high level of dietitians' critical reasoning. A categorized overview of indicators is provided to support this process. Lastly, the consortium developed a checklist to give dietitians a handle on what elements could be included in their M&OE plan and trigger them to perform M&OE in practice. CONCLUSIONS: Innovative M&OE models may help dietitians to demonstrate their effectiveness in improving clinical outcomes and justify their role in health care. PMID- 30274900 TI - Association between fibre intake and indoxyl sulphate/P-cresyl sulphate in patients with chronic kidney disease: Meta-analysis and systematic review of experimental studies. AB - BACKGROUND AND OBJECTIVE: Indoxyl sulphate (IS) and p-cresyl sulphate (PCS), which are difficult to excrete adequately out of the body, are closely related to the progression of chronic kidney disease (CKD) and various deuteropathy. Better than peritoneal dialysis (PD) and haemodialysis (HD), dietary fibre has been considered to reduce IS and PCS levels. In view of the absence of formal recommendations on fibre intake in CKD nutritional guidelines, we conducted this meta-analysis to assess the effects of dietary fibre on IS and PCS for CKD patients. METHODS: The effects were pooled and expressed in terms of weighted mean difference (WMD) with 95% confidence interval (95% CI). Q test and I2 statistics were used to assess the heterogeneity. RESULTS: A total of 12 relevant estimates from 7 reports, including 203 CKD patients, showed that dietary fibre significantly reduced their PCS level (WMD = -16.160, 95% CI: -23.824, -8.495). CONCLUSIONS: The meta-analysis produced a strong corroboration that dietary fibre intake does have a good therapeutic effect on patients with CKD. The conclusions need to be validated by randomised controlled experiments (RCT) with better design, larger samples, longer course of treatment and higher quality. PMID- 30274901 TI - Patient experiences of initial trauma care. AB - BACKGROUND: Correct initial treatment of trauma patients reduces mortality and morbidity. However, the initial examination may be perceived as traumatic because of the stressful situation, the unfamiliar setting and the shock of being seriously injured. To date, little is known about patient's experiences of initial trauma management. The aim of this study was to explore trauma patients' experiences of being exposed to initial full trauma team assessment at a Level 1 trauma centre. METHODS: Interviews with 16 patients who had been exposed to initial trauma care were conducted at a Level 1 trauma centre, at a Swedish University Hospital. The interviews were transcribed verbatim and analysed with qualitative content analysis. RESULTS: Patients' experiences of initial trauma care can be summarized as: feeling safe in a frightening situation. The trauma team members were mostly perceived as professional, well-organised, and efficient. Yet, the patients described an emotional response to the trauma, physical discomfort during the examination, and feeling prioritised or being ignored in the encounter with the trauma team members. CONCLUSION: The initial trauma care may be improved if the trauma team members keep the patient's physical and emotional wellbeing in focus and maintain an informative dialogue with the patient during the whole process. PMID- 30274902 TI - Management of immune thrombocytopenia in elderly patients. AB - Despite the improvement in understanding its pathogenesis and the introduction of novel treatment options, the management of primary immune thrombocytopenia (ITP) still remains challenging. Considering its increased incidence with aging and prolonged life-expectancy, ITP is often diagnosed in elderly patients, a subset that deserves some special precautions. Ensure the diagnosis is a crucial step, and carefully attention must be given in excluding other causes of thrombocytopenia, especially among older people that frequently suffer from many comorbidities. When it comes to treatment decision, it is worth keeping into account that the elderly have an increased risk of bleeding, thrombosis and infections, that they often require many concomitant therapies, including antiplatelet or anticoagulant agents, and that treatment-related toxicities are often increased and sometimes more dangerous that the disease itself. There are not dedicated guidelines, and only few specific studies. Steroids with or without IVIG remain the first-line treatment. Splenectomy is less effective than in youngers and burdened by an increased thrombotic and infectious risk. Rituximab is a good option in non-immunocompromised patients, but long-term remissions are few. Eltrombopag and romiplostim have a good safety and efficacy profile, and have become a prominent drug in this subset, even if they are associated with a possible increased risk of thrombosis, and long-term toxicity is unknown. Other drugs, such as dapsone and danazol, have a well-known efficacy and safety profile, and still represent a valid option among elderly patients.

AB - Despite an increasing body of knowledge on the adverse clinical sequelae associated with late preterm birth and early term birth, little is known about their economic consequences or the cost-effectiveness of interventions aimed at their prevention or alleviation of their effects. This review assesses the health economic evidence surrounding late preterm and early term birth. Evidence is gathered on hospital resource use associated with late preterm and early term birth, economic costs associated with late preterm and early term birth, and economic evaluations of prevention and treatment strategies. The article highlights the limited perspective and time horizon of most studies of economic costs in this area; the limited evidence surrounding health economic aspects of early term birth; the gaps in current knowledge; and it discusses directions for future research in this area, including the need for validated tools for measuring preference-based health-related quality-of-life outcomes in infants that will aid cost-effectiveness-based decision-making.

PMID- 30274906 TI - Ideal Cardiovascular Health and Incident Cardiovascular Disease Among Adults: A Systematic Review and Meta-analysis. AB - OBJECTIVE: To investigate the association between ideal cardiovascular health (CVH) metrics and incident cardiovascular disease (CVD) by conducting a systematic review and meta-analysis of prospective cohort studies. METHODS: The MEDLINE, EMBASE, and CINAHL databases were searched from January 1, 2010, through July 31, 2017, for studies that met the following criteria: (1) prospective studies conducted in adults, (2) with outcome data on CVD incidence and (3) a measure of ideal CVH metrics. RESULTS: Twelve studies (210,443 adults) were included in this analysis. Compared with adults who met 0 to 2 of the ideal CVH metrics (high-risk individuals), a significantly lower hazard for CVD incidence was observed in those who had 3 to 4 points for the ideal CVH metrics (hazard ratio [HR]=0.53; 95% CI, 0.47-0.59) and 5 to 7 points (HR=0.28; 95% CI, 0.23 0.33). Weaker associations were observed in studies with older individuals, suggesting that there is a positive relationship between age and HR. CONCLUSION: Although meeting 5 to 7 metrics is associated with the lowest hazard for CVD incidence, meeting 3 to 4 metrics still offers an important protective effect for CVD. Therefore, a realistic goal in the general population in the short term could be to promote at least an intermediate ideal CVH profile (3 to 4 metrics). PMID- 30274907 TI - Effect of Cognitive Status on the Receipt of Procedures Requiring Anesthesia and Critical Care Admissions in Older Adults. AB - OBJECTIVE: To investigate whether older adults with mild cognitive impairment (MCI) or dementia have higher rates of procedures requiring general anesthesia or intensive care unit (ICU) admissions compared with cognitively normal (CN) patients. PATIENTS AND METHODS: A population-based cohort, 70 to 89 years old at enrollment, underwent clinical and longitudinal neurocognitive testing to identify those with MCI and dementia. We analyzed the effects of cognitive status (CN, MCI, or dementia) at entry into the study from October 1, 2004, through December 31, 2014, on the risk of receiving procedures requiring surgical anesthesia and ICU admission. RESULTS: Of 2436 participants, 1977 (81%) were CN, 387 (16%) had MCI, and 72 (3%) had dementia. Cognitively impaired individuals were sicker. Compared with CN individuals, the likelihood of receiving a procedure requiring anesthesia was similar in participants with MCI (adjusted hazard ratio [aHR]=0.98; P=.78). Participants with dementia were less likely to receive these procedures (aHR=0.50; P=.02). Compared with CN participants, the likelihood of ICU admission for any indication was increased for those with MCI (aHR=1.24; P=.03) and dementia (aHR=1.59; P=.04). Admissions to the ICU after procedures were not different in patients with either MCI or dementia (aHR=0.96; P=.83 and aHR=1.01; P=.98, respectively). CONCLUSION: Patients with MCI or dementia are not more likely to undergo surgery, and neither are they more likely to require ICU admission after procedures. An increased rate of nonsurgical ICU admissions requires vigilance to prevent deterioration of nonsurgical diseases that may lead to ICU admissions. PMID- 30274908 TI - Concordance and Discordance of Sexual Identity, Sexual Experience, and Current Sexual Behavior in 45-Year-Old Men: Results From the German Male Sex-Study. AB - INTRODUCTION: Discordance of various aspects of sexual orientation has been mostly studied in young adults or in small samples of heterosexual men. Studies focusing on concordance and discordance of aspects of sexual orientation in representative samples of middle-aged men including homosexual men are scarce. AIM: To investigate concordant and discordant sexual behavior in 45-year-old German men with a special focus on homosexual identified men. METHODS: Data for this cross-sectional study were collected within the German Male Sex-Study. Participants were 45-year-old Caucasian males from the general population. Men self-reported on sexual identity, sexual experience, and current sexual behavior. Associations between sexual identity, experience, and behavior were analyzed using the chi-square test. MAIN OUTCOME MEASURE: Associations of sexual identity with sexual experience and behavior in a community-based sample of men, and discordance of sexual identity and behavior especially in the subgroup of homosexual men. RESULTS: 12,354 men were included in the study. 95.1% (n = 11.749) self-identified as heterosexual, 3.8% (n = 471) as homosexual, and 1.1% (n = 134) as bisexual. Sexual identity was significantly associated with sexual experience and behavior. 85.5% of all men had recently been sexually active, but prevalence of sexual practices varied. In hetero- and bisexuals, vaginal intercourse was the most common sexual practice, whereas oral sex was the most common in homosexuals. A discordance of sexual identity was especially found in homosexual men: 5.5% of homosexuals only had sexual experiences with women, and 10.3% of homosexuals recently had vaginal intercourse. In this latter subgroup, only one-quarter ever had sexual experience with a man, and three-quarters had only engaged in sexual activity with a woman. CONCLUSION: Sexual identity is associated with differences in sexual experience and behavior in German middle aged men. A considerable proportion of homosexual identified men live a heterosexual life. Goethe VE, Angerer H, Dinkel A, et al.

AB - INTRODUCTION: In Europe and the United States, verteporfin (Visudyne; VP) is registered and used in treating macular degeneration. Research showed that VP decreased expression of fibrotic genes in fibroblasts collected from nodules of patients suffering from Dupuytren's disease, plausibly by de-activating transcription in the Yes Activated Protein (YAP) pathway. AIM: To analyze the effect of VP on myofibroblasts cultured from Peyronie's disease (PD) plaques. METHODS: At surgery for PD we took biopsies from the plaques of 5 patients. By immunostaining, the presence of the pathologic myofibroblasts was determined. After culturing cells, VP was dispensed in starvation medium for 24 and 48 hours and messenger(m)RNA levels of COL1A1, ACTA2, COL5A1, EDA-FN, LOXL2, CCN2, SERPINH1, PLOD2, and YAP were quantified and compared with controls with real time polymerase chain reaction. MAIN OUTCOME MEASURE: mRNA-levels of COL1A1, ACTA2, COL5A1, EDA-FN, LOXL2, CCN2, SERPINH1, PLOD2, and YAP. RESULTS: The pathologic phenotype of cells isolated from PD plaques was confirmed with baseline immunofluorescent stainings that showed considerable levels of alpha smooth muscle actin, being a marker for the presence of myofibroblasts. The mRNA ratios of all the genes related to fibrosis (COL1A1, etc.) except YAP decreased significantly after treatment with VP within 24 and 48 hours. These results suggest inhibition of fibrosis in the YAP cascade, downstream of YAP. CONCLUSION: In our opinion, urologists must move the focus to disease before deformity, and the search for new oral or intralesional agents, well-tolerated and effective in both the acute and chronic phase of PD must continue. VP blocked the expression of genes related to fibrosis in the YAP cascade in myofibroblasts derived from PD plaque. Mohede DCJ, de Jong IJ, Bank RA, et al.

PMID- 30274910 TI - Simvastatin ameliorates total liver ischemia/reperfusion injury via KLF2-mediated mechanism in rats. AB - OBJECTIVE: The total hepatic ischemia/reperfusion injury (IRI) involves the fact that both liver and gut are subjected to warm ischemia, which is a complex unavoidable process encountered during liver transplantation and a serious threat to graft outcome. The ways to improve hepatic IRI are currently limited. The aim of the present study was to explore the protective effect of simvastatin on total hepatic IRI and examine the underlying mechanisms. METHODS: Male Sprague Dawley rats were subjected to total (100%) hepatic warm ischemia to induce hepatic IRI. Thirty-six male rats (250-300 g) were randomly divided into three groups: sham, IRI control and simvastatin (1 mg/kg) pretreatment 0.5 h before surgery. Serum samples and liver tissues were collected after reperfusion at 6 and 24 h for further studies. RESULTS: Simvastatin pretreatment significantly decreased the values of the transaminases alanine aminotransferase and aspartate aminotransferase and improved histological alterations according to improved Suzuki's Score (P < 0.05). Moreover, simvastatin upregulated the expression of Kruppel-like factor 2 (KLF2), phosphorylated endothelial nitric oxide synthase and thrombomodulin (P < 0.05). Furthermore, simvastatin pretreatment affected superoxide dismutase and malondialdehyde activities (P < 0.05) to reduce oxidative stress, and inhibited levels of high-mobility group box-1, CD68, toll like receptor 4, tumor necrosis factor alpha, interleukin-1beta and interleukin-6 (P < 0.05) to suppress inflammatory response. CONCLUSION: Simvastatin pretreatment ameliorates total hepatic IRI via a KLF2-mediated protective mechanism. Simvastatin may be used as a potential prophylactic treatment strategy for clinical trials against hepatic IRI. PMID- 30274912 TI - Effect of Fat Grafting on Postoperative Intraabdominal Adhesions on a Rat Model. AB - BACKGROUND: We aimed to evaluate the effect of fat grafting on postoperative intraabdominal adhesions by promoting mesothelial healing on a rat model. METHODS: Thirty Wistar albino rats were grouped as control and fat grafted group. They all underwent laparotomy, anterior cecal wall abrasion and peritoneal injury. On postoperative day 14, all surviving rats were sacrificed and adhesions, fibrosis and inflammation were graded using quantitative scoring systems. RESULTS: Fat grafting significantly reduced adhesion formation compared to the control group (p <0.002), less fibrosis (p <0.025) and less inflammation (p <0.024). CONCLUSIONS: Autologous intraperitoneal fat grafting promotes mesothelial healing in serosal and peritoneal injury rat model. The present study underlines the benefits of the pluripotent stem cell reservoir fat tissue and points to a new area of use. Results are promising for reducing adhesions, adhesion related morbidities and cost burden via a simple, cheap and applicable method; autologous fat grafting. PMID- 30274911 TI - Association of glycated hemoglobin with the risk of advanced fibrosis in non alcoholic fatty liver disease patients without diabetes. AB - BACKGROUND: Association of diabetes with non-alcoholic steatohepatitis has been well documented. However, it remains unclear whether there is an association between levels of glycated hemoglobin (HbA1c) with severity of non-alcoholic fatty liver disease (NAFLD). This study was aimed to explore the relationship between levels of HbA1c and the risk of advanced fibrosis in patients with NAFLD. METHODS: A cross-sectional study was performed on 4826 apparently healthy Chinese, who underwent a health check between January 2015 and December 2016. NAFLD was defined as hepatic steatosis on ultrasonography in the absence of excessive alcohol use or other identifiable causes. The risk of advanced fibrosis was assessed by NAFLD fibrosis Score. RESULTS: Among 4826 individuals studied, 1630 were diagnosed with NAFLD. In a multivariable-adjusted model, high HbA1c levels were associated independently with increased prevalence of NAFLD. The adjusted odds ratio [95% confidence interval (95% CI)] for NAFLD, when compared with the highest HbA1c quartile and the lowest HbA1c quartile, was 2.72 (2.07 3.58; P for trend < 0.001). A strong association was also observed between HbA1c level and the risk of fibrosis in patients with NAFLD in multivariable analyses, with the extreme-quartile odds ratio of 2.69 (95% CI: 1.60-4.53; P for trend < 0.001). This association remained significant even in subjects without diabetes. CONCLUSIONS: We concluded that high HbA1c level was associated strongly and independently with increased risk of advanced fibrosis in NAFLD patients without diabetes. PMID- 30274913 TI - Association Between miR-149 Gene rs2292832 Polymorphism and Risk of Gastric Cancer. AB - BACKGROUND AND AIMS: Accumulating evidence suggested that microRNA (miRNA) genes take part in different processes associated with gastric cancer (GC). The single nucleotide polymorphisms (SNPs) located on miRNA sequences may affect the interaction with their target mRNAs and consequently the genetic susceptibility to GC. MATERIALS/METHODS: A hospital-based case-control study with 320 cases and 354 controls was conducted to investigate the association between miR-149 gene rs2292832 polymorphism and GC susceptibility in a Chinese Han population. RESULTS: TT genotype or T allele carriers of miR-149 gene rs2292832 polymorphism increased the risk of GC. Furthermore, a meta-analysis together with this study between this SNP and GC risk was performed. In the allele association study, meta analysis between this polymorphism and GC risk showed that T or C allele was not associated with the risk of GC, but TC genotype carriers of miR-149 gene rs2292832 polymorphism were associated with decreased risk of GC (TC vs. CC, heterozygote model: OR and 95% CI, 0.80 [0.67,0.96]). Stratification analysis of ethnicity in this meta-analysis indicated that rs2292832 polymorphism decreased the risk of GC among Caucasians (TT + TC vs. CC, dominant model: OR and 95% CI, 0.69 (0.50,0.97); TC vs. CC, heterozygote model: OR and 95% CI, 0.68 [0.47,0.97]), while this SNP increased the risk of GC among Asians (TT vs. TC + CC, recessive model: OR and 95% CI, 1.24 [1.04,1.48]; T vs. C, allele model: OR and 95% CI, 1.13 [1.00,1.28]). CONCLUSION: This case-control study and meta analysis confirm that miR-149 gene rs2292832 polymorphism is associated with increased risk of GC among Asians.

PMID- 30274915 TI - [New guidelines on dyslipidemia management: Comparison of French (HAS) and European (ESC/EAS) guidelines]. AB - Total cardiovascular risk estimation using a system such as SCORE is recommended for adults>40years of age without evidence of cardiovascular disease, diabetes, chronic kidney disease, severe hypertension or familial hypercholesterolemia. Before treatment, a full lipid profile is recommended, fasting in French guidelines, fasting or non-fasting in European guidelines. LDL-C has to be used as the primary target for treatment. For patients with elevated triglycerides, non-HDL-C level is also recommended as the secondary goal for treatment. In patients at very high and high cardiovascular risk, LDL-C goals are respectively below<0.70g/L and<1.0g/L. For subjects at very high and high cardiovascular risk, French guidelines do not mention that a>=50% reduction in LDL-C should be achieved. Statins are the treatment of choice to reach LDL-C goals. If the goal is not reached on maximally tolerated dose of statin, combination with another LDL lowering drug, mainly ezetimibe, is recommended. Fibrates are mainly proposed for patients with severe hypertriglyceridemia (TG>5g/L after lifestyle changes). PMID- 30274916 TI - [Challenges in the management of amiodarone-induced thyrotoxicosis]. AB - Amiodarone, a benzofuranic iodine-rich pan antiarrhythmic drug, is frequently associated with thyroid dysfunction. This side effect is heterogeneous and unpredicted, motivating regular evaluation of thyroid function tests. In contrary to hypothyroidism, amiodarone-induced thyrotoxicosis (AIT) is a challenging situation owing to the risk of deterioration of the general and cardiac status of such debilitating patients. Classically, AIT is either an iodine-induced thyrotoxicosis in patients with an abnormal thyroid (type I), or due to a subacute thyroiditis on a "healthy" thyroid (type II). Even if many studies tried to better identify the types of AIT, the diagnostic dilemma of type of AIT could be present, and many patients are treated by an association of antithyroid drugs (useful for type I AIT) with corticoids (useful for type II AIT). Being the main etiological factor in AIT, amiodarone is supposed to be stopped, but it could remain the only anti-arrhythmic option that is needed to be either continued or reintroduced to improve the cardiovascular survival. Recently, many studies demonstrated that amiodarone could be continued or reintroduced in patients with history of type II AIT. Nevertheless, in the other patients, amiodarone maintenance complicates the therapeutic response to the antithyroid drugs and increases the risk of AIT recurrence. Thus, amiodarone therapy is preferred to be interrupted. In such patients, thyroid ablation is recommended once AIT is under control. PMID- 30274917 TI - Identification of 34 novel mutations in propionic acidemia: Functional characterization of missense variants and phenotype associations. AB - Propionic acidemia (PA) is caused by mutations in the PCCA and PCCB genes, encoding alpha and beta subunits, respectively, of the mitochondrial enzyme propionyl-CoA carboxylase (PCC). Up to date, >200 pathogenic mutations have been identified, mostly missense defects. Genetic analysis in PA patients referred to the laboratory for the past 15 years identified 20 novel variants in the PCCA gene and 14 in the PCCB gene. 21 missense variants were predicted as probably disease-causing by different bioinformatics algorithms. Structural analysis in the available 3D model of the PCC enzyme indicated potential instability for most of them. Functional analysis in a eukaryotic system confirmed the pathogenic effect for the missense variants and for one amino acid deletion, as they all exhibited reduced or null PCC activity and protein levels compared to wild-type constructs. PCCB variants p.E168del, p.Q58P and p.I460T resulted in medium-high protein levels and no activity. Variants p.R230C and p.C712S in PCCA, and p.G188A, p.R272W and p.H534R in PCCB retained both partial PCC activity and medium-high protein levels. Available patients-derived fibroblasts carriers of some of these mutations were grown at 28 degrees C or 37 degrees C and a slight increase in PCC activity or protein could be detected in some cases at the folding-permissive conditions. Examination of available clinical data showed correlation of the results of the functional analysis with disease severity for most mutations, with some notable exceptions, confirming the notion that the final phenotypic outcome in PA is not easily predicted.

It is an inflammatory disorder associated with BRAF V600E mutation in 50% of cases. This multisystem disease is rarely associated with spinal involvement. Neurological involvement is an independent predictive factor of poor prognosis. The diagnosis is histopathological based on CD68-positive and CD1A-negative histiocytes. Treatment with interferon-alpha is an independent predictor of survival in Erdheim-Chester disease and vemurafenib has also been shown to be effective for BRAF V600E mutation. We report a clinical case of a 51-year-old patient with multiple and rare locations of Erdheim-Chester disease, particularly at the sphenoid sinus. PMID- 30274920 TI - Composite Health Outcomes in Pediatric and Young Adult Kidney Transplant Recipients. AB - OBJECTIVE: To assess composite health outcomes in pediatric and young adult kidney transplant recipients following kidney transplantation. STUDY DESIGN: We conducted a cross-sectional study of all recipients at our center who had a 1-, 3 , 5-, and/or 10-year transplant anniversary visit between October 2008 and February 2015. The kidney transplant recipients were assessed at each time point according to an outcome measure consisting of 15 pass/fail criteria in 5 domains: allograft health, rejection and immunology, infection, cardiovascular health, and growth. RESULTS: We analyzed 148 patients at 231 transplantation anniversary visit time points; 52 of 82 (63%) patients assessed at 1 year had an ideal outcome, meeting at least 13 of the 15 criteria. This decreased to 37% at year 3, 40% at year 5, and 26% at year 10 (P < .01). The most common failures across all time points occurred in the domains of growth (43%-52% passing) and cardiovascular health (33%-51% passing). Allograft health declined significantly, decreasing from 74% at year 1 to 33% at year 10 (P < .01). The percentage of patients with graft failure increased from 2.4% at 1 year to 39.5% at 10 years (P < .01), and patient deaths increased from 0 to 11% (P < .01) in the same time frame. CONCLUSIONS: Ideal outcomes for pediatric kidney transplant recipients decrease over time with growth, cardiovascular health, and allograft health as the primary failure modes. Understanding the composite health of young recipients will allow primary care providers and nephrologists alike to evaluate the overall health of kidney transplant recipients and focus clinical care on the most common sequelae.

PMID- 30274922 TI - Longitudinal Associations between Neurodevelopment and Psychosocial Health Status in Patients with Repaired D-Transposition of the Great Arteries. AB - OBJECTIVE: To examine associations between measurements of neurodevelopment and psychosocial health status at age 8 and 16 years in patients with repaired dextro transposition of the great arteries. STUDY DESIGN: In the 16-year follow-up of the Boston Circulatory Arrest Study, 137 parents completed the Child Health Questionnaire-Parent Form-50, of whom 135 had completed the Child Health Questionnaire-Parent Form-50 when their child was age 8 years. Psychosocial and physical summary scores were used to assess change in health status from age 8 to 16 years. A comprehensive battery of neurodevelopmental testing was performed at ages 8 and 16 years to examine associations with adolescent health status. RESULTS: Lower psychosocial summary scores of 16 year old subjects with dextro transposition of the great arteries were highly associated with numerous concurrent domains of neurodevelopmental function, most notably with higher (worse) scores on the Conners' Attention Deficit Hyperactivity Disorder/Diagnostic and Statistical Manual-4th Edition Scales (parent: r = -0.62, P <.001; adolescent: r = -0.43, P < .001) and the Behavior Rating Inventory of Executive Function Global Executive Composite (parent: r = -0.66, P <.001; adolescent: r = -0.39, P <.001). Psychosocial and physical summary scores tracked from ages 8 to 16 years (r = 0.44 and 0.47, respectively, P <.001 for each). Higher (worse) scores of multiple attention measures at age 8 years predicted worse psychosocial summary scores at age 16 years. CONCLUSIONS: Attention deficits at age 8 years were highly predictive of worse psychosocial health status in adolescence. Further studies are needed to assess whether treatment of childhood attention deficit hyperactivity disorder could improve adolescent well being. PMID- 30274923 TI - Opioid Prescribing Practices for Pediatric Headache. AB - OBJECTIVES: To characterize the frequency of opioid prescribing for pediatric headache in both ambulatory and emergency department (ED) settings, including prescribing rates by provider type. STUDY DESIGN: A retrospective cohort study of Washington State Medicaid beneficiaries, aged 7-17 years, with an ambulatory care or ED visit for headache between January 1, 2012, and September 30, 2015. The primary outcome was any opioid prescribed within 1 day of the visit. RESULTS: A total of 51 720 visits were included, 83% outpatient and 17% ED. There was a predominance of female (63.2%) and adolescent (59.4%) patients, and 30.5% of encounters involved a pediatrician. An opioid was prescribed in 3.9% of ED and 1.0% of ambulatory care visits (P < .001). Pediatricians were less likely to prescribe opioids in both ED (-2.70 percentage point; 95% CI, -3.53 to -1.88) and ambulatory settings (-0.31 percentage point; 95% CI, -0.54 to -0.08; P < .001). CONCLUSIONS: Opioid prescribing rates for pediatric headache were low, but significant variation was observed by setting and provider specialty. We identified opioid prescribing by nonpediatricians as a potential target for quality improvement efforts.

PMID- 30274925 TI - All Aboard Meal Train: Can Child-Friendly Menu Labeling Promote Healthier Choices in Hospitals? AB - OBJECTIVE: To evaluate patient meal orders and consumption with a revised menu design that includes child-friendly labeling. STUDY DESIGN: A randomized controlled trial among hospitalized children was performed over a 1-month period comparing the control menu layout and the intervention menu. The intervention menu contained the same choices but was labeled to encourage healthy eating. Children on a specialized diet, receiving parenteral nutrition, or age <2 years were excluded. RESULTS: A total of 163 patients (81 males) were included, with a mean age of 9.9 +/- 5.1 year, and a mean weight z-score of -0.08 +/- 1.3. Children receiving the intervention ordered more "green-light" healthy choices and fewer "red-light" items, with 0.65 lower odds of selecting a red-light item (95% CI, 0.55-0.76) and 1.75 higher odds of selecting a green-light item (95% CI, 1.49-2.04), both at the first meal, but with effects waning over time. There were trends toward increased intake of fruits and vegetables and decreased intake of "foods to limit", but no impact on the consumption of sugar-sweetened beverages. Both intervention and control group consumed their meals in equal proportions. CONCLUSIONS: The combination of menu labeling techniques targeted to children in the inpatient hospital setting was an effective short-term tool for increasing the intake of healthier foods, although the effect of labeling waned over time. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02692001. PMID- 30274926 TI - Racial and Ethnic Disparities in the Use of Mother's Milk Feeding for Very Low Birth Weight Infants in Massachusetts. AB - OBJECTIVE: To examine the extent to which maternal race/ethnicity is associated with mother's milk use among hospitalized very low birth weight (VLBW) infants and maternal receipt of hospital breastfeeding support practices (human milk prenatal education, first milk expression <6 hours after delivery, lactation consultation <24 hours, any skin-to-skin care <1 month). STUDY DESIGN: We studied 1318 mother-VLBW infant pairs in 9 Massachusetts level 3 neonatal intensive care units (NICUs) between January 2015 and November 2017. We estimated associations of maternal race/ethnicity with any and exclusive mother's milk on day 7, on day 28, and at discharge/transfer and hospital practices. We estimated HRs comparing the probability of continued milk use over the hospitalization by race/ethnicity and tested mediation by hospital practices, adjusting for birth weight and gestational age and including hospital and plurality as random effects. RESULTS: Mothers were 48% non-Hispanic white, 21% non-Hispanic black, and 20% Hispanic. Initiation of mother's milk was similar across groups, but infants of Hispanic mothers (hazard ratio [HR], 2.71; 95% CI, 2.05-3.59) and non-Hispanic black mothers (HR, 1.55; 95% CI, 1.17-2.07) stopped receiving milk earlier in the hospitalization compared with infants of non-Hispanic white mothers. Hispanic mothers had lower odds of providing skin-to-skin care at <1 month (OR, 0.61; 95% CI, 0.43-0.87) compared with non-Hispanic whites. CONCLUSIONS: Hispanic and non Hispanic black mothers were less likely than non-Hispanic white mothers to continue providing milk for their VLBW infants throughout the NICU stay.

AB - OBJECTIVES: To investigate the association of soft drink consumption and the intake of sugar from soft drinks with the prevalence of acne in adolescents. STUDY DESIGN: This was a university-based epidemiologic investigation that included 8226 students who underwent health examinations and a questionnaire survey inquiring about the intake of soft drinks. Skin diseases were diagnosed by certificated dermatologists during the health examination. Two-level logistic and generalized additive models were used to estimate the associations, and aORs were presented as the effect size. RESULTS: A total of 8197 student survey responses were analyzed. Frequent intake (>=7 times per week) of carbonated sodas (aOR 1.61, 95% CI 0.96-2.72), sweetened tea drinks (aOR 2.52, 95% CI 1.43-4.43), and fruit-flavored drinks (aOR 1.90, 95% CI 1.18-3.07) was associated with moderate to-severe acne after adjustments for confounders. The occasional intake of fruit flavored drinks (1-2 times per week) had a weak protective effect on acne (aOR 0.86, 95% CI 0.74-0.99). The intake of sugar from any soft drinks showed a nonlinear association with acne (P < .01), and sugar intake >=100 g/d was significantly associated with moderate-to-severe acne (aOR 3.12, 95% CI 1.80 5.41). CONCLUSIONS: Daily soft drink consumption significantly increases the risk of moderate-to-severe acne in adolescents, especially when the sugar intake from any type of soft drink exceeds 100 g per day.

PMID- 30274932 TI - The immune cell infiltrate in the microenvironment of vulvar Paget disease. AB - BACKGROUND: Non-invasive vulvar Paget disease (VPD) is a rare skin disorder mainly affecting elderly women. Recently, the immune modulator imiquimod was reported as an effective treatment option. Knowledge about the immune microenvironment of VPD is lacking. METHODS: This study investigates the basic characteristics of the immune infiltrate in VPD (n = 10); moreover the influence of imiquimod was studied (n = 6). Immunohistochemistry for CD4, CD8, CD14, CD20, CD56 and FoxP3 was performed. The infiltrates of VPD were compared to vulvar high grade squamous cell intraepithelial lesions (HSIL) (n = 43), a HPV induced vulvar premalignancy with known response to imiquimod cream, and healthy controls (n = 30). Immune cell counts in samples taken before and after treatment were compared. RESULTS: The microenvironment in VPD differs from the healthy vulvar skin and vulvar HSIL. VPD is characterized by a decrease in immune cells in the epithelium and an abundant number of immune cells in the stroma, consisting predominantly of T cells. The intraepithelial CD8+/Foxp3+ ratio and number of CD56+ increased after imiquimod therapy, whereas the numbers of CD14+ cells decreased which may point to a treatment-induced type 1 immune response. CONCLUSIONS: The epithelium in VPD contains less immune cells, but a dense stromal immune infiltrate. Changes in immune cell counts after immune modulation in relation to clinical responses should be further investigated. PMID- 30274933 TI - CDKN2A germline mutations are not associated with poor survival in an Italian cohort of melanoma patients. AB - BACKGROUND: Cyclin dependent kinase inhibitor 2A gene (CDKN2A) germline mutations have recently been associated with poor survival in patients with melanoma. Despite the high mutation rate in our cohort (up to 10% in patients with apparently sporadic melanoma), information on the impact of CDKN2A on survival in this cohort is lacking. OBJECTIVE: To investigate whether poor survival associated with CDKN2A germline mutations was confirmed in a high mutation prevalence cohort of Italian patients with melanoma undergoing a mutation-based follow-up. METHODS: A total of 1239 patients with cutaneous melanoma were tested for CDKN2A mutational status and then assigned to a follow-up scheme according not only to family history but also to CDKN2A mutational status, as follow-up intervals were more frequent for CDKN2A germline mutation-positive (MUT+) patients. From this cohort, we selected 106 MUT+ patients (with familial melanoma or apparently sporadic melanoma) and 199 CDKN2A germline mutation-negative (MUT-) patients with sporadic melanoma who were matched by age and sex and had a similar tumor stage distribution. RESULTS: We found no difference in overall survival (hazard ratio, 0.85; 95% confidence interval, 0.48-1.52; P = .592,) or melanoma specific survival (hazard ratio, 0.86; 95% confidence interval, 0.38-1.95; P = .718,) between MUT+ and MUT- patients. MUT+ patients were more likely to develop multiple melanomas and to undergo surgical excision of dysplastic nevi than were MUT- patients. LIMITATIONS: Retrospective study. CONCLUSION: CDKN2A mutations were not associated with survival in our cohort. PMID- 30274934 TI - The POWER-tool: Recommendations for involving patient representatives in choosing relevant outcome measures during rare disease clinical trial design. AB - In clinical trials, it is relevant to ask patients and/or their caregivers which aspects concerning their disease they consider important to measure when a new intervention is being investigated. Those aspects, useful as outcome measures in a trial, are of pivotal importance for the result of the trial and the subsequent decision-making. In rare diseases the choice of outcome measures may be even more important, due to the small numbers and heterogeneity of the patients that are included. We have developed a tool to involve patients in the determination of outcome measures and the choice of measurement instruments. This tool was developed together with a patient think tank, consisting of a group of rare disease patient representatives, and by interviewing end users. We have road tested our tool in an ongoing trial, and evaluated it during a focus group meeting. The tool consists of three steps: 1) Preparation, 2) Consultation of patients, 3) Follow-up during which the consultation results are implemented in the trial design. The tool provides guidelines for researchers to include the patient's opinion in the choice of outcome measures in the trial design stage. We describe the development of the POWER-tool (Patient participation in Outcome measure WEighing for Rare diseases), and first experiences of the tool in an ongoing trial. PMID- 30274935 TI - Voluntary associations and co-production of health promoting activities for older adults: Experiences and policy lessons from Denmark. AB - Demographic transitions in Europe accentuate the need to develop innovative solutions for healthy ageing. One increasingly popular policy approach is co production between local governments and voluntary community associations (VCOs) to promote activities for health and wellbeing among older adults. While co production has been studied from the perspective of local governments there is limited knowledge regarding how voluntary associations perceive their conditions. This study aims to fill this gap using survey data from voluntary associations in Denmark. The investigation is based on an electronic survey (n = 263) of VCOs engaged in activities relevant for healthy ageing in three Danish municipalities. The survey addressed 13 issues and potential problems within four categories - ''members and volunteers', 'economics, 'media and the public' and ''politics and the local government'. The paper presents a relatively positive picture of the potentials in municipal-VCO collaboration. However, we also find that a sizeable number of VCOs point to problems and obstacles particular in regards to recruitment of members and economics. While the municipalities in our study have all developed strategies to support VCOs and to promote coproduction it seems that there are deficits in the implementation of the strategies. This leads us to conclude that municipalities must pay close attention to the issues and conditions for VCOs in order to succeed with their policy initiatives in this area. PMID- 30274936 TI - Assessing quality of primary diabetes care in South Korea and Taiwan using avoidable hospitalizations. AB - Quality of primary diabetes care is a key health policy concern in many OECD countries with an aging population. This cross-national, population-based study examined the extent and attributes of diabetes-related avoidable hospitalizations (DRAHs) in South Korea and Taiwan, both of which have social health insurance based health systems with limited gate-keeping for hospitalizations. We analyzed comparable, nationally representative health insurance beneficiary datasets for the two countries (2002-2013), linked with community health resource data. The age- and sex-standardized DRAH rates were calculated, and multivariate, multi level longitudinal modeling approaches were adopted. The DRAH rate decreased in Taiwan consistently during 2002-2013 and in Korea after 2011 only. Under the universal health coverage, people enjoyed high accessibility to care. A higher number of physician visits reduced DRAHs in Korea but not in Taiwan. Socio economic disparities in DRAHs still existed in both countries, especially in Taiwan. We found a different trajectory in two similar health systems for the selected health system performance indicator for primary diabetes care. This can be partly explained by different policy approaches to diabetes management in the two countries over the years. Necessary are policy efforts to improve the quality and equality of primary diabetes care and better control of hospital admissions in these two health systems that provide generous access to care at a low cost in East Asia. PMID- 30274937 TI - Working capital management policy in health care: The effect of leverage. AB - Hospitals, which are mainly capital intensive, require large amounts of financial resources to render high-quality services. Accordingly, health care managers and policy makers should take into account the level of debt in managing working capital. This study, therefore, aims to explore whether the financial leverage moderates the relationship between the working capital and profitability for the publicly-listed European Hospitals. The data set including 52 hospitals with 468 observations was solicited from the ORBIS. A regression analysis was carried out. The results reveal that increasing the length of the cash conversion cycle for hospitals with high financial leverage decreases profitability. On the contrary, increasing the length of the cash conversion cycle for the ones having low leverage boosts profitability. The findings of this study suggest that since leverage influences the relationship between the cash conversion cycle and profitability, the degree of financial leverage is an important indicator to be considered by health care managers and policy makers in managing working capital. In addition, by clarifying the effect of leverage, this study helps policy makers understand and estimate the possible impact of working capital changes on profitability. This study also helps managers and decision makers not only apply a tight working capital policy but also decide whether to increase or decrease the length of cash conversion cycle to improve hospital profitability. PMID- 30274938 TI - Hemodynamic and clinical performance of Solo stentless bioprosthetic aortic valves. AB - OBJECTIVE: To report the hemodynamic profile and short- and medium-term outcomes of Freedom Solo and Solo Smart stentless aortic valves implanted at our center. METHODS: Between 2009 and 2015, all patients undergoing aortic valve replacement using Solo stentless valves at our center were enrolled. Clinical and echocardiographic follow-up was carried out six months postoperatively. Survival and major events, including structural valve deterioration and non-structural valve dysfunction, endocarditis, reoperation and stroke, were assessed through medical records or telephone interview with the referring cardiologist up to November 2015 (mean and maximum follow-up 39+/-22 and 78 months, respectively). RESULTS: Patients' (n=345) mean age was 72+/-8 years, 52% were female and median euroSCORE II was 2.7 (1.5-4.7). There was no intraoperative mortality and in hospital mortality was 2.6%. Postoperatively, mean transvalvular gradient was 11.9+/-4.5 mmHg and effective orifice area was 1.9+/-0.5 cm2. Patient-prosthesis mismatch occurred in 14% but was severe in only one patient. Cumulative survival at six years was 72%. Six patients were reoperated: three due to endocarditis, two for structural prosthesis deterioration and one because of periprosthetic fistula. Five patients suffered stroke, three had medically-treated endocarditis and one had structural valve deterioration but was not considered suitable for reoperation. None of the remainder had structural valve deterioration or non structural valve dysfunction. CONCLUSIONS: Solo stentless aortic valves are safe to implant, with promising clinical outcomes in short- and medium-term assessment. Moreover, they show an excellent hemodynamic performance: low transvalvular gradients, large effective orifice areas and low incidence of patient-prosthesis mismatch. PMID- 30274940 TI - Design and synthesis of thiazolylhydrazone derivatives as inhibitors of chitinolytic N-acetyl-beta-d-hexosaminidase. AB - N-acetyl-beta-d-hexosaminidase (Hex) is potential target for pesticide design. Here, a series of thiazolylhydrazone derivatives were designed, synthesized and evaluated as competitive inhibitors of OfHex1, a Hex from the agricultural pest Ostrinia furnacalis. The derivative 3k, with a (benzyloxy)methyl group at the N3 atom, demonstrated greater potency with a Ki of 10.2 uM. Molecular docking analysis indicated that the (benzyloxy)methyl group of 3k was bound to a previously unexplored pocket formed by Loop478-496. Then further optimization around naphthalene ring led to find the more potency substituent phenyl. The derivative 7, with phenoxyethyl group at R1 and a phenyl group at R2, demonstrated an augmented potency with a Ki of 2.1 uM. Molecular docking analysis indicated that 7 was bound to the active pocket of OfHex1 more favorably than 3k. This work suggests a novel scaffold for developing specific Hex inhibitors. PMID- 30274939 TI - Identification of DK419, a potent inhibitor of Wnt/beta-catenin signaling and colorectal cancer growth. AB - The Wnt signaling pathway is critical for normal tissue development and is an underlying mechanism of disease when dysregulated. Previously, we reported that the drug Niclosamide inhibits Wnt/beta-catenin signaling by decreasing the cytosolic levels of Dishevelled and beta-catenin, and inhibits the growth of colon cancers both in vitro and in vivo. Since the discovery of Niclosamide's anthelmintic activity, a growing body of literature indicates that Niclosamide is a multifunctional drug. In an effort to identify derivatives of Niclosamide with improved pharmacokinetic properties that maintain the multifunctional drug activity of Niclosamide for clinical evaluation, we designed DK419, a derivative containing a 1H-benzo[d]imidazole-4-carboxamide substructure, using the structure activity relationships (SAR) of the Niclosamide salicylanilide chemotype. Similar to Niclosamide, we found DK419 inhibited Wnt/beta-catenin signaling, altered cellular oxygen consumption rate and induced production of pAMPK. Moreover, we found DK419 inhibited the growth of CRC tumor cells in vitro, had good plasma exposure when dosed orally, and inhibited the growth of patient derived CRC240 tumor explants in mice dosed orally. DK419, a derivative of Niclosamide with multifunctional activity and improved pharmacokinetic properties, is a promising agent to treat colorectal cancer, Wnt-related diseases and other diseases in which Niclosamide has demonstrated functional activity. PMID- 30274941 TI - A novel 2,4-diaminopyrimidine derivative as selective inhibitor of protein kinase C theta prevents allograft rejection in a rat heart transplant model. AB - Protein kinase C theta (PKCtheta) plays a critical role in T cell signaling and is an attractive target for the treatment of T cell-mediated diseases such as transplant rejection and autoimmune disease. To identify PKCtheta inhibitors, we focused on the 2,6-diamino-3-carbamoyl-5-cyanopyrazine derivative 2, which exhibited moderate PKCtheta inhibitory activity. Optimization of 2 identified the 2,4-diamino-5-cyanopyrimidine derivative 16c, which exhibited potent PKCtheta inhibitory activity and showed good selectivity against other PKC isozymes. Compound 16c prolonged graft survival in an in vivo rat heterotopic cardiac transplant model. PMID- 30274943 TI - Marijuana Use During Pregnancy. PMID- 30274942 TI - Impact of weekend treatment on short-term and long-term survival after urgent repair of ruptured aortic aneurysms in Germany. AB - OBJECTIVE: There is some evidence that weekend admission to the hospital is associated with worse outcomes compared with weekday admission. However, only a few studies have focused on weekend vs weekday surgery outcomes. This study aimed to determine whether there is a weekend effect on outcomes in the treatment of ruptured aortic aneurysms in Germany. METHODS: Health insurance claims of Germany's third largest insurance provider, DAK-Gesundheit, were used to investigate short-term and long-term mortality after weekend vs weekday treatment of ruptured aortic aneurysm. Patients undergoing endovascular repair (ER) or open surgical repair (OSR) between January 2008 and December 2016 were included in the study. Both propensity score matching and regression methods were used to adjust for confounding. RESULTS: There were 1477 patients in the cohort, of whom 517 (35.0%) underwent ER and 960 (65.0%) OSR. Overall, 995 (67.4%) patients underwent an operation on weekdays (Monday to Thursday), and 482 (32.6%) patients underwent an operation on a weekend (Friday to Sunday). In multivariable models, patients who underwent an operation on a weekend were at higher risk of in-hospital death after OSR (49.2% vs 38.0%; odds ratio [OR], 1.61; P = .001), and there was a trend toward higher in-hospital mortality after ER (29.5% vs 21.2%; OR, 1.55; P = .056). The ER of thoracic or thoracoabdominal aortic ruptures was associated with significantly higher in-hospital mortality compared with ER of abdominal aortic aneurysm (OR, 1.69; P = .026). CONCLUSIONS: Weekend repairs of ruptured aortic aneurysms are associated with worse in-hospital survival compared with weekday surgery. ER of thoracic or thoracoabdominal aortic ruptures is associated with worse in-hospital survival compared with ER of ruptured abdominal aortic ruptures. This might be an international phenomenon requiring joint learning and action in times of centralization of aortic procedures. PMID- 30274944 TI - Women's Cardiovascular Health. PMID- 30274945 TI - Psychiatric comorbidity in multiple sclerosis. AB - AIM: To study the prevalence of psychiatric comorbidities in patients of multiple sclerosis and their association to the degree of disability. METHOD: Psychiatric symptoms were assessed in 90 patients of multiple sclerosis using GHQ-12, MMSE, HADS, Beck Depression Inventory and AUDIT. Neurological disability was assessed using Expanded Disability Status Scale. Correlations were determined between EDSS scores and psychiatric scale scores. RESULT: 61% of patients had significant psychological distress. Depression was most common (38.8%) which was followed by anxiety symptoms (27.8%). Cognitive functioning was relatively intact in patients with mild to moderate neurological disability. Alcohol abuse was mostly restricted to male gender. CONCLUSION: Psychiatric illness is highly prevalent in patients of multiple sclerosis leading to poor quality of life and significant distress. Psychiatric disability was higher in patients who had greater deterioration in neurological function. All cases of MS should be assessed for psychiatric morbidities as can be alleviated by appropriate intervention. PMID- 30274946 TI - Emergency Medical Services Use Among Patients Receiving Involuntary Psychiatric Holds and the Safety of an Out-of-Hospital Screening Protocol to "Medically Clear" Psychiatric Emergencies in the Field, 2011 to 2016. AB - STUDY OBJECTIVE: Patients with acute psychiatric emergencies who receive an involuntary hold often spend hours in the emergency department (ED) because of a deficit in inpatient psychiatric beds. One solution to address the lack of prompt psychiatric evaluation in the ED has been to establish regional stand-alone psychiatric emergency services. However, patients receiving involuntary holds still need to be screened and evaluated to ensure that their behavior is not caused by an underlying and life-threatening nonpsychiatric illness. Although traditional regional emergency medical services (EMS) systems depend on the medical ED for this function, a field-screening protocol can allow EMS to directly transport a substantial portion of patients to a stand-alone psychiatric emergency service. The purpose of this investigation is to describe overall EMS use for patients receiving involuntary holds, compare patients receiving involuntary holds with all EMS patients, and evaluate the safety of field medical clearance of an established field-screening protocol in Alameda County, CA. METHODS: We obtained data for all EMS encounters between November 1, 2011, and November 1, 2016, using Alameda County's standardized data set. After unique patient identification, we describe the data at the patient level and at the encounter level. At the patient level, we compare "involuntary hold patients" (>=1 involuntary hold during the study period) with those who were "never held." Additionally, we assess the safety of out-of-hospital medical clearance by calculating the rate of failed diversion, defined as retransport of a patient to a medical ED within 12 hours of transport to the psychiatric emergency services by EMS. RESULTS: Of the 541,731 total EMS encounters in Alameda County during the study period, 10% (N=53,887) were identified as involuntary hold encounters. Of these involuntary hold patient encounters, 41% (N=22,074) resulted in direct transport of the patient to the stand-alone psychiatric emergency service for evaluation; 0.3% (N=60) failed diversion and required retransport within 12 hours. At the patient level, Alameda County EMS encountered 257,625 unique patients, and 10% (N=26,283) had at least one encounter for an involuntary hold during the study period. These "involuntary hold patients" were substantially younger, more likely to be men, and less likely to be insured. Additionally, they had higher overall EMS use: "involuntary hold patients" accounted for 24% of all encounters (N=128,003); 53,887 of these encounters were for involuntary holds, whereas an additional 74,116 were for other reasons. Similarly, 4% of "involuntary hold patients" had 20 or more encounters, whereas only 0.4% of "never held" patients were in this category. Last, the 7% of "involuntary hold patients" (N=1,907) who received greater than or equal to 5 involuntary holds during the study period accounted for 39% of all involuntary holds and 9% of all EMS encounters. CONCLUSION: Ten percent of all EMS encounters were for involuntary psychiatric holds. With an EMS-directed screening protocol, 41% of all such patient encounters resulted in direct transport of the patient to the psychiatric emergency service, bypassing medical clearance in the ED. Overall, only 0.3% of these patients required retransport to a medical ED within 12 hours of arrival to psychiatric emergency services. We found that 24% of all EMS encounters in Alameda County were attributable to "involuntary hold patients," reinforcing the importance of the effects of mental illness on EMS use. PMID- 30274947 TI - Cumulative Long-Term Incidence of Postoperative Periprosthetic Femoral Fractures Using an Uncemented Tapered Titanium Hip Stem: 26- to 32-Year Results. AB - BACKGROUND: Although falling is becoming a major problem in the elderly, little is known about the long-term incidence of postoperative periprosthetic femoral fractures (PFF) after total hip arthroplasty (THA) using uncemented stems with a minimum follow-up of 26 years postoperatively. METHODS: In a consecutive series, the cumulative incidence of PFF after uncemented THA using a straight, collarless, tapered titanium stem was retrospectively reviewed in 354 hips (326 patients). After a mean follow-up of 28 (26-32) years postoperatively, 179 hips had died and 5 hips had been lost to follow-up. Kaplan-Meier survival analysis was used to estimate cumulative percentage probability of PFF. RESULTS: At final follow-up, a total of 27 fractures in 27 patients had occurred. In 15 hips, the stem had to be revised, and in 10 the fracture was treated by open reduction and internal fixation. Two patients declined further surgery. The cumulative percentage probability of PFF was 1.6% (95% confidence interval, 0.7 to 3.8) at 10 years and 13.2% (95% confidence interval, 8.5 to 20.2) at 29 years after primary THA. There was no association between the occurrence of fracture and gender, age at primary THA, cup revision, or canal fill index. CONCLUSION: Our findings indicate that PFF is the major mode of failure in the long term after uncemented THA using a tapered titanium stem. More research is needed to evaluate the reasons and risk factors for PFF after THA, thus providing better prophylaxis for those at risk and to compare the long-term incidence using different fixation methods and implants. LEVEL OF EVIDENCE: IV. PMID- 30274948 TI - Medical student education in transfusion medicine: Proposal from the "European and Mediterranean initiative in transfusion medicine". AB - A large body of observations indicate that there is an inconsistent knowledge of Transfusion Medicine among health care professionals as well as inconsistent knowledge in all aspects of the transfusion process, from blood donation to transfusion on the ward. It is obvious to consider that appropriate education in Transfusion Medicine should be achieved in the education of specialists who will prescribe transfusion on a regular basis (hematologists, critical care specialists, anaethesiologists and others.) However,we also believe that education in Transfusion Medicine should also be delivered to almost all other medical specialists who may prescribe blood components. The variability in education of undergraduates in medical schools is universal most likely due to an absence of a predefined common platform. This paper, therefore, focuses on education at the undergraduate level and advocates coverage of the essential physiology and pathophysiology of blood as applied to blood transfusion as well as the medical and societal aspects of issues related to blood donation. It proposes incremental levels of training in Transfusion Medicine, with what is being therefore referred to as 'A', 'B', 'C' etc. curricula in ascending order of complexity; for example, 'A' and 'B' levels would involve medical, midwifery and nursing students, covering a broad base of the subject: they will be detailed in the present essay; ongoing further curricula will focus on physicians and other professionals working within the area or with responsibility for different aspects of the transfusion chain. It is intended that these courses include aspects of donor care, patient care and the appropriate use, safety and effectiveness of blood products. Next, it is advocated that curricula are addressed not only for high-income countries but also for middle- and low-income ones. PMID- 30274949 TI - The utility of therapeutic plasma exchange for amphotericin B overdose. AB - Medication error is a preventable cause of morbidity and death in the inpatient population. We describe a patient with an antifungal overdose treated with therapeutic plasma exchange (TPE). The patient was diagnosed with cryptococcal meningitis and received an acute overdose of amphotericin B deoxycholate instead of the prescribed liposomal amphotericin B. Consequently, the patient developed clinical symptoms including tremors, hypertension, visual hallucinations, vertigo, fever, and acute renal failure. A series of four TPEs was emergently initiated, resulting in complete resolution of most symptoms. PMID- 30274950 TI - Extreme lateral and interlaminar approach for intra-canal and foraminal double disc herniation at lumbosacral level. AB - INTRODUCTION AND OBJECTIVES: There are several approaches for double disc herniation consisting of an intracanal and foraminal lesion. Of several approaches, we introduced extreme lateral and interlaminar approach (ELIA). And we aimed to compare the approach with the conventional combined interlaminar and paraisthmic approach (CIPA). PATIENTS AND METHODS: The authors reviewed the medical charts of patients who underwent a procedure for a double disc herniation at the lumbosacral level between March 2012 and February 2016 and patients who underwent CIPA or ELIA were selected. For preoperative testing, simple X-ray, computed tomography (CT), and magnetic resonance imaging (MRI) scans were performed. For postoperative outcomes, the Korean version of the Oswestry Disability Index (K-ODI) and Numeric Rating Scale (NRS) at one, two, and three months post-operation were checked. RESULTS: Eleven patients were given ELIA and twenty-four patients were involved in CIPA. The mean pre K-ODI was 34.1 (+/-13.9) and 32.4 (+/-4.0) at each group. 1st, 2nd and 3rd month post-operative K-ODI was 8.2 (+/-4.1), 6.4 (+/-2.1) and 5.3 (+/-2.4) in ELIA and 8.1 (+/-3.2), 7.1 (+/ 3.5) and 8.4 (+/-6.4) in CIPA. Post-operative 3rd month K-ODI showed significant difference between two groups (p: 0.005). The mean pre NRS was 8 (+/-0.9) and 8.6 (+/-1.0). 1st, 2nd and 3rd month post-operative NRS was 2.4 (+/-1.5), 2.2 (+/ 1.5) and 2.0 (+/-0.9) in ELIA and 3.3 (+/-1.4), 3.3 (+/-1.6) and 3.7 (+/-1.9). Post-operative 3rd month NRS showed significant difference between two groups as well (p: 0.001). There were four (19.0%) recurrence cases in CIPA patients group, otherwise there was no recurrence case in ELIA group. CONCLUSIONS: In the treatment of L5-S1 double disc herniation, the ELIA surgical approach showed better outcomes than the CIPA surgical approach did with respect to pain and K ODI during a mid-term follow-up examination conducted three months post operation. PMID- 30274951 TI - Nested PCR for the detection of Aspergillus species in maxillary sinus samples of patients with chronic sinusitis. AB - BACKGROUND: Fungal rhinosinusitis has become an increasingly recognized disease, being Aspergillus species responsible for most of the cases. Its diagnosis is quite difficult because of the non-specific symptoms and low sensitivity of the current diagnostic methods. AIMS: An Aspergillus-specific nested polymerase chain reaction (PCR) assay using biopsy specimens taken from the maxillary sinuses was performed in order to assess its usefulness. Conventional diagnostic methods (histology and culture) were also carried out. METHODS: A case-control study was performed in the Institute of Stomatology, Jagiellonian University in Krakow, between 2011 and 2014. The case group consisted of 21 patients with suspected rhinosinusal mycetoma while the control group included 46 patients with no suspicion of fungal rhinosinusitis. The two-step PCR assay amplified an Aspergillus specific portion of the 18S rRNA gene. Interval estimation of sensitivity, specificity, positive (PPV) and negative (NPV) predictive values were calculated to assess the diagnostic test performance. The agreement between the PCR and the other tests was evaluated using the Kappa coefficient (k). RESULTS: Ninety percent of the samples obtained from patients diagnosed with mycetoma yielded positive PCR results. The PCR showed almost perfect concordance with histology (k=0.88). Sensitivity, specificity, PPV and NPV estimates were 90%; 95% CI: (55.5-99.7%), 98.3%; 95% CI: (90.9-100%), 90%; 95% CI: (55.5-99.7%) and 98.3%; 95% CI: (90.9-100%), respectively. One clinical sample showed growth of Aspergillus fumigatus and positive PCR despite the negative histological examination. CONCLUSIONS: Nested PCR assay is a promising diagnostic tool to evaluate the presence of Aspergillus in the tissue of maxillary sinus from patients with suspicion of sinus aspergillosis. PMID- 30274952 TI - First isolation and molecular characterization of Cryptococcus neoformans var. grubii in excreta of birds in the urban perimeter of the Municipality of Popayan, Colombia. AB - BACKGROUND: Cryptococcosis is a systemic opportunistic mycosis, caused by Cryptococcus neoformans and Cryptococcus gattii, which affects mainly the central nervous system of immunocompromised patients; no reports have been made on the isolation of the fungus from the environment of Popayan, Colombia. AIMS: The main objective of this investigation was to determinate the incidence of C. neoformans in the urban perimeter in the City of Popayan, Colombia. METHODS: A total of 303 samples from droppings of Columba livia and Bubulcus ibis were collected between September 2012 and June 2013. The samples were processed by conventional techniques; identification of colonies was performed by biochemical tests, and molecular patterns were determined by PCR fingerprinting with the primer (GTG)5 and restriction fragment length polymorphism (RFLP) of the gene URA5. RESULTS: A total of 118 (38.94%) samples were positive for Cryptococcus in excreta of C. livia, and 361 strains belonging to Cryptococcus neoformans var. grubii were isolated. From the latter, 99.2% corresponded to the molecular pattern VNI and 0.8% to VNII, with an increased occurrence (24.4%) at a temperature of 22.5 degrees C and a humidity of 60.8%. The excreta of B. ibis did not show the presence of the fungus. CONCLUSIONS: C. livia excreta is a key environmental niche for C. neoformans var. grubii, type VNI, supporting growth and reproduction, and serving as a major source of infection for susceptible populations in Popayan. This represents the first report on the isolation of the agent of cryptococcosis from the environment in this region, with a significant prevalence in bird excreta.

PMID- 30274954 TI - [First report of a case of fungal keratitis due to Curvularia hominis in Spain]. AB - BACKGROUND: Dematiaceous fungal genus Curvularia is a causal agent of keratitis, onychomycosis, and skin infections. In 2014, using DNA sequencing techniques, five new species, including Curvularia hominis, were described. In this article, a report is presented on the first clinical case of C.hominis infection in Spain. It concerns a corneal ulcer caused by this recently described species. CASE REPORT: A 46 year-old male patient with a corneal ulcer in his left eye went to the Emergency Department. Specimens were obtained from the lesion, and the patient was admitted due to the risk of corneal perforation. The fungal culture of the specimens revealed a filamentous fungus that was identified by microscopic examination as Curvulariaspp. Using mass spectrometry (MALDI-TOF) the isolate was identified as Curvularia lunata. To confirm the identification, the isolate was sent to the National Centre of Microbiology in Spain, where ITS region sequencing was performed, and it was finally identified as C.hominis. The patient received voriconazole and progressed favourably. To repair the corneal damage, the patient received an amniotic membrane transplantation. CONCLUSIONS: C.hominis should be considered a causal agent of keratitis and sequencing techniques are now necessary for species-level identification of Curvularia isolates. This is the first case report in Spain caused by this species. PMID- 30274955 TI - [Clinical features and outcome in patients with mucormycosis in a tertiary hospital (2012-2016)]. AB - BACKGROUND: The most common presentation of mucormycosis in the past was the nasosinusal involvement in patients with diabetic ketoacidosis. However, in the last few years, new groups of patients with risk of mucormycosis have emerged. AIMS AND METHODS: Retrospective analysis of the characteristics, treatment and evolution of patients with mucormycosis in a tertiary hospital in the years 2012 2016. RESULTS: Of the 12 patients included in the study, 7 had a haematological disease as a predisposing factor, most of them (6 patients) related to transplantation of haematopoietic progenitors. Only one patient had diabetic ketoacidosis. Seven out of the twelve patients were receiving an antifungal treatment at the onset of symptoms, and 9 patients had received them three months before. The clinical presentation was rhinosinusal (16.6%), localised lung disease (33.3%), and musculoskeletal (25%) and disseminated disease (25%). Surgical debridement was performed on 8 patients. Combination therapy with amphotericin B and posaconazole was received by 6 patients (16% mortality), and 4 patients were treated with amphotericin B alone (50% mortality), with an overall mortality of 41%. The mortality of patients with pulmonary involvement was 71%, increasing to 100% in the case of disseminated disease. None of the patients with only musculoskeletal involvement died. CONCLUSIONS: Mucormycosis has a high mortality rate, especially the pulmonary forms. Musculoskeletal involvement had a better prognosis. The main group at risk was that of patients with haematopoietic stem cell transplantation. Combination therapy had better results than monotherapy, although more experience is needed to define the most appropriate treatment. PMID- 30274956 TI - Machine learning for real-time prediction of complications in critical care: a retrospective study. AB - BACKGROUND: The large amount of clinical signals in intensive care units can easily overwhelm health-care personnel and can lead to treatment delays, suboptimal care, or clinical errors. The aim of this study was to apply deep machine learning methods to predict severe complications during critical care in real time after cardiothoracic surgery. METHODS: We used deep learning methods (recurrent neural networks) to predict several severe complications (mortality, renal failure with a need for renal replacement therapy, and postoperative bleeding leading to operative revision) in post cardiosurgical care in real time. Adult patients who underwent major open heart surgery from Jan 1, 2000, to Dec 31, 2016, in a German tertiary care centre for cardiovascular diseases formed the main derivation dataset. We measured the accuracy and timeliness of the deep learning model's forecasts and compared predictive quality to that of established standard-of-care clinical reference tools (clinical rule for postoperative bleeding, Simplified Acute Physiology Score II for mortality, and the Kidney Disease: Improving Global Outcomes staging criteria for acute renal failure) using positive predictive value (PPV), negative predictive value, sensitivity, specificity, area under the curve (AUC), and the F1 measure (which computes a harmonic mean of sensitivity and PPV). Results were externally retrospectively validated with 5898 cases from the published MIMIC-III dataset. FINDINGS: Of 47 559 intensive care admissions (corresponding to 42 007 patients), we included 11 492 (corresponding to 9269 patients). The deep learning models yielded accurate predictions with the following PPV and sensitivity scores: PPV 0.90 and sensitivity 0.85 for mortality, 0.87 and 0.94 for renal failure, and 0.84 and 0.74 for bleeding. The predictions significantly outperformed the standard clinical reference tools, improving the absolute complication prediction AUC by 0.29 (95% CI 0.23-0.35) for bleeding, by 0.24 (0.19-0.29) for mortality, and by 0.24 (0.13-0.35) for renal failure (p<0.0001 for all three analyses). The deep learning methods showed accurate predictions immediately after patient admission to the intensive care unit. We also observed an increase in performance in our validation cohort when the machine learning approach was tested against clinical reference tools, with absolute improvements in AUC of 0.09 (95% CI 0.03-0.15; p=0.0026) for bleeding, of 0.18 (0.07-0.29; p=0.0013) for mortality, and of 0.25 (0.18-0.32; p<0.0001) for renal failure. INTERPRETATION: The observed improvements in prediction for all three investigated clinical outcomes have the potential to improve critical care. These findings are noteworthy in that they use routinely collected clinical data exclusively, without the need for any manual processing. The deep machine learning method showed AUC scores that significantly surpass those of clinical reference tools, especially soon after admission. Taken together, these properties are encouraging for prospective deployment in critical care settings to direct the staff's attention towards patients who are most at risk.

AB - INTRODUCTION: Although links between ejaculatory control or intravaginal ejaculatory latency time and female sexual functioning have frequently been reported in the past, no study has investigated the importance of other male ejaculatory characteristics, such as ejaculation volume and intensity, for women's sexuality. AIM: To assess the importance of subjectively perceived ejaculation intensity and ejaculation volume for female sexual function and satisfaction. METHODS: This was a cross-sectional online survey including 240 sexually active, heterosexual women (median age 27.4 years), using study-specific questions and validated questionnaires. MAIN OUTCOME MEASURE: Results are presented as means, percentages, and age-controlled partial correlation coefficients of the main study variables. RESULTS: 50.43% of women considered it very important that the partner ejaculates during intercourse. 18.3% of women preferred that the partner ejaculates before they reach orgasm, whereas for 53.5% this did not matter. 22.6% of women stated that they experienced a more intense orgasm when their partner ejaculated during vaginal intercourse. 17.4% reported that they definitely experienced a more intensive orgasm depending on the intensity of their partner's ejaculation, whereas for 17.8% this did not matter at all. 20.9% of women did not feel that their orgasm was more intense depending on the subjectively felt ejaculate quantity, whereas the majority (37.9%) stated that it did not matter. 13.1% of women regarded the quantity of expelled ejaculate as an expression of their own sexual attractiveness. Women stating that they experienced more intense orgasms when the partner ejaculated, when the partner experienced a more intense ejaculation, and when he expelled a greater ejaculate quantity also reported better lifelong orgasmic function (r = 0.24, r = 0.15, r = .26, respectively) and more lifelong sexual satisfaction (r = .29, r = .15, r = 26, respectively). CLINICAL IMPLICATIONS: The perception of ejaculatory characteristics can be related to the female partner's sexual satisfaction and overall sexual functioning. STRENGTH & LIMITATIONS: This is the very first study to explore the importance of male ejaculation volume and intensity for women's sexual functioning. Data are of self-report nature and ejaculation characteristics were not objectively measured but by women's self-report. CONCLUSION: Although male ejaculation and its different aspects seem to play an important role for women, the study demonstrates a considerable variability of women's attitudes toward ejaculatory characteristics. Further research is required to examine the sources of this variability. Burri A, Buchmeier J, Porst H. The importance of male ejaculation for female sexual satisfaction and function.

PMID- 30274958 TI - Complaint-Directed Mini-Interventions for Depressive Symptoms: A Health Economic Evaluation of Unguided Web-Based Self-Help Interventions Based on a Randomized Controlled Trial. AB - BACKGROUND: Depression prevention and early intervention have become a top priority in the Netherlands, but with considerable room for improvement. To address this, Web-based complaint-directed mini-interventions (CDMIs) were developed. These brief and low-threshold interventions focus on psychological stress, sleep problems, and worry, because these complaints are highly prevalent, are demonstrably associated with depression, and have substantial economic impact. OBJECTIVE: The objective of this economic evaluation was to examine the added value of Web-based, unguided, self-help CDMIs compared with a wait-listed control group with unrestricted access to usual care from both a societal and a health care perspective. METHODS: This health economic evaluation was embedded in a randomized controlled trial. The study entailed 2 arms, in which 3 Web-based CDMIs were compared with a no-intervention waiting-list control group (which received the intervention after 3 months). We conducted measurements at baseline, and at 3 and 6 months. The primary outcome was the rate of responders to treatment on depressive symptoms as measured by the Inventory of Depressive Symptomatology Self-Report (IDS-SR). We estimated change in quality of life by calculating effect sizes (Cohen d) for individual pre- and posttreatment IDS-SR scores using a conversion factor to map a change in standardized effect size onto a corresponding change in utility. We calculated incremental cost-effectiveness ratios using bootstraps (5000 times) of seemingly unrelated regression equations and constructed cost-effectiveness acceptability curves for the costs per quality adjusted life-year (QALY) gained. RESULTS: Of 329 study participants, we randomly assigned 165 to the CDMI group. At 3 months, the rate of responders to treatment was 13.9% (23/165) in the CDMI group and 7.3% (12/164) in the control group. At 3 months, participants in the CDMI group gained 0.15 QALYs compared with baseline, whereas participants in the control group gained 0.03 QALYs. Average total costs per patient at 3 months were ?2094 for the CDMI group and ?2230 for the control group (excluding baseline costs). Bootstrapped seemingly unrelated regression equations models resulted in a dominant incremental cost-effectiveness ratio (ie, lower costs and a higher rate of responders to treatment) for the CDMI group compared with the control group at 3 months, with the same result for the costs per QALY gained. Various sensitivity analyses attested to the robustness of the findings of the main analysis. CONCLUSIONS: Brief and low-threshold Web-based, unguided, self-help CDMIs have the potential to be a cost-effective addition to usual care for adults with mild to moderate depressive symptoms. The CDMIs improved health status, while reducing participant health care costs, and hence dominated the care-as-usual control condition. As intervention costs were relatively low, and the internet is readily available in the Western world, we believe CDMIs can be easily implemented on a large scale.

PMID- 30274959 TI - Physician and Pharmacist Medication Decision-Making in the Time of Electronic Health Records: Mixed-Methods Study. AB - BACKGROUND: Primary care needs to be patient-centered, integrated, and interprofessional to help patients with complex needs manage the burden of medication-related problems. Considering the growing problem of polypharmacy, increasing attention has been paid to how and when medication-related decisions should be coordinated across multidisciplinary care teams. Improved knowledge on how integrated electronic health records (EHRs) can support interprofessional shared decision-making for medication therapy management is necessary to continue improving patient care. OBJECTIVE: The objective of our study was to examine how physicians and pharmacists understand and communicate patient-focused medication information with each other and how this knowledge can influence the design of EHRs. METHODS: This study is part of a broader cross-Canada study between patients and health care providers around how medication-related decisions are made and communicated. We visited community pharmacies, team-based primary care clinics, and independent-practice family physician clinics throughout Ontario, Nova Scotia, Alberta, and Quebec. Research assistants conducted semistructured interviews with physicians and pharmacists. A modified version of the Multidisciplinary Framework Method was used to analyze the data. RESULTS: We collected data from 19 pharmacies and 9 medical clinics and identified 6 main themes from 34 health care professionals. First, Interprofessional Shared Decision-Making was not occurring and clinicians made decisions based on their understanding of the patient. Physicians and pharmacists reported indirect Communication, incomplete Information specifically missing insight into indication and adherence, and misaligned Processes of Care that were further compounded by EHRs that are not designed to facilitate collaboration. Scope of Practice examined professional and workplace boundaries for pharmacists and physicians that were internally and externally imposed. Physicians decided on the degree of the Physician-Pharmacist Relationship, often predicated by colocation. CONCLUSIONS: We observed limited communication and collaboration between primary care providers and pharmacists when managing medications. Pharmacists were missing key information around reason for use, and physicians required accurate information around adherence. EHRs are a potential tool to help clinicians communicate information to resolve this issue. EHRs need to be designed to facilitate interprofessional medication management so that pharmacists and physicians can move beyond task-based work toward a collaborative approach. PMID- 30274960 TI - Health Information Discrepancies Between Internet Media and Scientific Papers Reporting on Omega-3 Supplement Research: Comparative Analysis. AB - BACKGROUND: Dietary supplements are the most used complementary and alternative health modality in the United States, and omega-3 supplements continue to be the most popularly used nonvitamin or nonmineral supplements by adults. Users of dietary supplements report that they obtain health guidance from internet media resources, but there is question as to whether or not these resources provide the necessary evidence to guide health decisions. Current evidence suggests that there is a mistranslation occurring somewhere between researchers and the media. OBJECTIVE: The aim of this study was to conduct a comparative cross-sectional analysis to identify areas of discordance created when science is translated from the laboratory to Web-based news media. METHODS: A Google news search provided our convenience sample of 40 omega-3 supplement-based media reports stratified by the years 2009 to 2012. Media reports (n=17) were compared with the corresponding scientific papers for content. Report and scientific paper content were extracted using commonly accepted reporting guideline domains, and domains were then compared for detecting underlying omissions or mistranslations in reporting. Mean scores for all of the scientific papers and media reports were assessed for each domain. RESULTS: Scientific papers (n=14) generally maintained a mean close to complete for each reporting domain. The only domain where there was not a significant difference between media and scientific reporting match was within the objectives domain (chi21= 0.8, P=.36). Media reports (n=17) more frequently reported potential caveats and warnings for consumers with a mean domain for caveat reporting of 0.88, with possible scores falling between 0 and 1. CONCLUSIONS: There are inherent differences in the intended audience, structure, and goals in scientific and media communications. These differences should be explored further, and consumers should be made aware of them. Additional considerations for balanced reporting and reader accessibility are also necessary to take into account and are explored further in this analysis. PMID- 30274961 TI - How Users Experience and Use an eHealth Intervention Based on Self-Regulation: Mixed-Methods Study. AB - BACKGROUND: eHealth interventions show stronger effects when informed by solid behavioral change theories; for example, self-regulation models supporting people in translating vague intentions to specific actions have shown to be effective in altering health behaviors. Although these theories inform developers about which behavioral change techniques should be included, they provide limited information about how these techniques can be engagingly implemented in Web-based interventions. Considering the high levels of attrition in eHealth, investigating users' experience about the implementation of behavior change techniques might be a fruitful avenue. OBJECTIVE: The objective of our study was to investigate how users experience the implementation of self-regulation techniques in a Web-based intervention targeting physical activity and sedentary behavior in the general population. METHODS: In this study, 20 adults from the general population used the intervention for 5 weeks. Users' website data were explored, and semistructured interviews with each of the users were performed. A directed content analysis was performed using NVivo Software. RESULTS: The techniques "providing feedback on performance," "action planning," and "prompting review of behavioral goals" were appreciated by users. However, the implementation of "barrier identification/problem solving" appeared to frustrate users; this was also reflected by the users' website data-many coping plans were of poor quality. Most users were well aware of the benefits of adopting a more active way of living and stated not to have learned novel information. However, they appreciated the provided information because it reminded them about the importance of having an active lifestyle. Furthermore, prompting users to self monitor their behavioral change was not sufficiently stimulating to make users actually monitor their behavior. CONCLUSIONS: Iteratively involving potential end users offers guidance to optimally adapt the implementation of various behavior change techniques to the target population. We recommend creating short interventions with a straightforward layout that support users in creating and evaluating specific plans for action. PMID- 30274962 TI - The Untapped Potential of the Gaming Community: Narrative Review. AB - BACKGROUND: Video gamers are a population at heightened risk of developing obesity due to the sedentary nature of gaming, increased energy intake, and the disruption caused to their sleep. This increases their risk of developing a number of noncommunicable diseases. To date, research seeking to improve health behaviors has focused on developing novel video games to promote behavior change. Although positive results have emerged from this research, large-scale success has been limited due to the lack of transferability to mainstream games and the focus on children and adolescents. The gaming community has a number of unique aspects, which have received comparatively less attention than the development of new video games. OBJECTIVE: The purpose of this paper is to highlight under researched areas that have the potential to encourage positive health behavior among this community. METHODS: A narrative review of the lay and academic literature was conducted to provide context and support to our claims that further research could be beneficial in this area. RESULTS: Research has found that advertising can have implicit effects on an individual's memories, which could influence later decisions. However, the effect of the exponential growth of in-game advertisements and the brand sponsorship of gaming events and professional gamers have not been explored in the gaming community. The possibility of using advertising techniques to encourage positive health behaviors within games or at these events has also not been explored. Research suggests that virtual communities can be effective at disseminating health information, but the efficacy of this needs to be explored using known community influencers within the gaming community. CONCLUSIONS: This paper has highlighted a number of potential avenues for the development of interventions within the gaming community. Further research must be conducted alongside game developers to ensure that any in-game developed interventions do not deter gameplay and gamers to ensure that potential approaches are acceptable. PMID- 30274963 TI - Web-Based Mindfulness Interventions for Mental Health Treatment: Systematic Review and Meta-Analysis. AB - BACKGROUND: Web-based mindfulness interventions are increasingly delivered through the internet to treat mental health conditions. OBJECTIVE: The objective of this study was to determine the effectiveness of web-based mindfulness interventions in clinical mental health populations. Secondary aims were to explore the impact of study variables on the effectiveness of web-based mindfulness interventions. METHODS: We performed a systematic review and meta analysis of studies investigating the effects of web-based mindfulness interventions on clinical populations. RESULTS: The search strategy yielded 12 eligible studies. Web-based mindfulness interventions were effective in reducing depression in the total clinical sample (n=656 g=-0.609, P=.004) and in the anxiety disorder subgroup (n=313, g=-0.651, P<.001), but not in the depression disorder subgroup (n=251, P=.18). Similarly, web-based mindfulness interventions significantly reduced anxiety in the total clinical sample (n=756, g=-0.433, P=.004) and the anxiety disorder subgroup (n=413, g=-0.719, P<.001), but not in the depression disorder group (n=251, g=-0.213, P=.28). Finally, web-based mindfulness interventions improved quality of life and functioning in the total sample (n=591, g=0.362, P=.02) in the anxiety disorder subgroup (n=370, g=0.550, P=.02) and mindfulness skills in the total clinical sample (n=251, g=0.724, P<.001). CONCLUSIONS: Results support the effectiveness of web-based mindfulness interventions in reducing depression and anxiety and in enhancing quality of life and mindfulness skills, particularly in those with clinical anxiety. Results should be interpreted with caution given the high heterogeneity of web-based mindfulness interventions and the low number of studies included. PMID- 30274964 TI - Monitoring Twitter Conversations for Targeted Recruitment in Cancer Trials in Los Angeles County: Protocol for a Mixed-Methods Pilot Study. AB - BACKGROUND: Insufficient recruitment of participants remains a critical roadblock to successful clinical research, particularly clinical trials. Social media provide new ways for connecting potential participants with research opportunities. Researchers suggest that the social network Twitter may serve as a rich avenue for exploring how patients communicate about their health issues and increasing enrollment in cancer clinical trials. However, there is a lack of evidence that Twitter offers practical utility and impact. OBJECTIVE: This pilot study aimed to examine the feasibility and impact of using Twitter monitoring data (ie, user activity and their conversations about cancer-related conditions and concerns expressed by Twitter users in Los Angeles County) as a tool for enhancing clinical trial recruitment at a comprehensive cancer center. METHODS: We will conduct a mixed-methods interrupted time series study design with a before-and-after social media recruitment intervention. On the basis of a preliminary analysis of eligible trials, we plan to onboard at least 84 clinical trials across 6 disease categories: breast cancer, colon cancer, kidney cancer, lymphoma, non-small cell lung cancer, and prostate cancer that are open to accrual at the University of Southern California (USC) Norris Comprehensive Cancer Center. We will monitor messages about these 6 cancer conditions posted by Twitter users in Los Angeles County. Recruitment for the trials will occur through the Twitter account (@USCTrials). Primary study outcomes-feasibility and acceptance of the social media intervention among targeted Twitter users and the study teams of the onboarded trials-will be assessed using qualitative interviews and the 4-point Likert scale and by calculating the proportion of targeted Twitter users who engaged with outreach messages. Second, impact of the social media intervention will be measured by calculating the proportion of enrollees in trials. The enrollment rate will be compared between the active intervention period and the prior 10 months as historical control for each disease trial group. This study has been funded by the National Center for Advancing Translational Science through a Clinical and Translational Science Award. Study approval was obtained from the clinical investigations committee at USC Norris and the institutional review board at USC. RESULTS: Recruitment on Twitter started in February 2018. Data collection will be completed in November 2018. CONCLUSIONS: This pilot project will provide preliminary data and practical insight into the application of publicly available Twitter data to identify and recruit clinical trial participants across 6 cancer disease types. We will shed light on the acceptance of the social media intervention among Twitter users and study team members of the onboarded trials. If successful, the findings will inform a multisite randomized controlled trial to determine the efficacy of the social media intervention across different locations and populations.

PMID- 30274965 TI - Early Detection of Cardiovascular Changes After Radiotherapy for Breast Cancer: Protocol for a European Multicenter Prospective Cohort Study (MEDIRAD EARLY HEART Study). AB - BACKGROUND: Breast cancer is the most common cancer among women, and radiotherapy plays a major role in its treatment. However, breast cancer radiotherapy can lead to incidental irradiation of the heart, resulting in an increased risk for a variety of heart diseases arising many years after radiotherapy. Therefore, identifying breast cancer patients at the highest risk for radiation-induced cardiac complications is crucial for developing strategies for primary and secondary prevention, which may contribute to healthy aging. There is still a need for precise knowledge on the relationship between radiation dose to specific cardiac structures and early subclinical cardiac changes and their occurrence over time that could finally lead to cardiac complications. OBJECTIVE: The MEDIRAD EARLY HEART study aims to identify and validate new cardiac imaging and circulating biomarkers of radiation-induced cardiovascular changes arising within first 2 years of breast cancer radiotherapy and to develop risk models integrating these biomarkers combined with precise dose metrics of cardiac structures based on three-dimensional dosimetry. METHODS: The EARLY HEART study is a multicenter, prospective cohort study in which 250 women treated for breast cancer and followed for 2 years after radiotherapy will be included. Women treated with radiotherapy without chemotherapy for a unilateral breast cancer and aged 40-75 years meet the inclusion criteria. Baseline and follow-up data include cardiac measurements based on two-dimensional speckle-tracking echocardiography, computed tomography coronary angiography, cardiac magnetic resonance imaging, and a wide panel of circulating biomarkers of cardiac injury. The absorbed dose will be evaluated globally for the heart and different substructures. Furthermore, the dose-response relationship will allow modeling the radiation-induced occurrence and evolution of subclinical cardiac lesions and biomarkers to develop prediction models. RESULTS: This study details the protocol of the MEDIRAD EARLY HEART study and presents the main limits and advantages of this international project. The inclusion of patients began in 2017. Preliminary results are expected to be published in 2019, and complete analysis should be published in 2021. CONCLUSIONS: The MEDIRAD EARLY HEART study will allow identifying the main cardiac imaging and blood-based determinants of radiation-induced cardiac injuries to better propose primary and secondary preventive measures in order to contribute to enhanced patient care and quality of life.

PMID- 30274966 TI - A Smartphone App to Foster Power in the Everyday Management of Living With Schizophrenia: Qualitative Analysis of Young Adults' Perspectives. AB - BACKGROUND: Literature indicates that using smartphone technology is a feasible way of empowering young adults recently diagnosed with schizophrenia to manage everyday living with their illness. The perspective of young adults on this matter, however, is unexplored. OBJECTIVE: This study aimed at exploring how young adults recently diagnosed with schizophrenia used and perceived a smartphone app (MindFrame) as a tool to foster power in the everyday management of living with their illness. METHODS: Using participatory design thinking and methods, MindFrame was iteratively developed. MindFrame consists of a smartphone app that allows young adults to access resources to aid their self-management. The app is affiliated with a website to support collaboration with their health care providers (HCPs). From January to December 2016, community-dwelling young adults with a recent diagnosis of schizophrenia were invited to use MindFrame as part of their care. They customized the resources while assessing their health on a daily basis. Then, they were invited to evaluate the use and provide their perspective on the app. The evaluation was qualitative, and data were generated from in-depth interviews. Data were analyzed using a hermeneutical approach. RESULTS: A total of 98 individuals were eligible for the study (mean age 24.8, range 18-36). Of these, 27 used MindFrame and 13 participated in the evaluation. The analysis showed that to the young adults, MindFrame served to foster power in their everyday management of living with schizophrenia. When MindFrame was used with the HCPs consistently for more than a month, it could provide them with the power to keep up their medication, to keep a step ahead of their illness, and to get appropriate help based on their needs. This empowered them to stay on track with their illness, thus in control of it. It was also reported that MindFrame could fuel the fear of restraint and illness exacerbation, thereby disempowering some from feeling certain and secure. CONCLUSIONS: The findings demonstrate that young adults diagnosed with schizophrenia are amenable to use a smartphone app to monitor their health, manage their medication, and stay alert of the early signs of illness exacerbation. This may empower them to stay on track with their illness, thus in control of it. This indicates the potential of smartphone-based care being capable of aiding this specific population to more confidently manage their new life situation. The potentially disempowering aspect of MindFrame accentuates a need for further research to understand the best uptake and the limitations of smartphone-based schizophrenia care of young adults. PMID- 30274968 TI - Twitter-Based Influenza Detection After Flu Peak via Tweets With Indirect Information: Text Mining Study. AB - BACKGROUND: The recent rise in popularity and scale of social networking services (SNSs) has resulted in an increasing need for SNS-based information extraction systems. A popular application of SNS data is health surveillance for predicting an outbreak of epidemics by detecting diseases from text messages posted on SNS platforms. Such applications share the following logic: they incorporate SNS users as social sensors. These social sensor-based approaches also share a common problem: SNS-based surveillance are much more reliable if sufficient numbers of users are active, and small or inactive populations produce inconsistent results. OBJECTIVE: This study proposes a novel approach to estimate the trend of patient numbers using indirect information covering both urban areas and rural areas within the posts. METHODS: We presented a TRAP model by embedding both direct information and indirect information. A collection of tweets spanning 3 years (7 million influenza-related tweets in Japanese) was used to evaluate the model. Both direct information and indirect information that mention other places were used. As indirect information is less reliable (too noisy or too old) than direct information, the indirect information data were not used directly and were considered as inhibiting direct information. For example, when indirect information appeared often, it was considered as signifying that everyone already had a known disease, leading to a small amount of direct information. RESULTS: The estimation performance of our approach was evaluated using the correlation coefficient between the number of influenza cases as the gold standard values and the estimated values by the proposed models. The results revealed that the baseline model (BASELINE+NLP) shows .36 and that the proposed model (TRAP+NLP) improved the accuracy (.70, +.34 points). CONCLUSIONS: The proposed approach by which the indirect information inhibits direct information exhibited improved estimation performance not only in rural cities but also in urban cities, which demonstrated the effectiveness of the proposed method consisting of a TRAP model and natural language processing (NLP) classification. PMID- 30274967 TI - Emergency Physician Use of the Alberta Netcare Portal, a Province-Wide Interoperable Electronic Health Record: Multi-Method Observational Study. AB - BACKGROUND: The adoption and use of an electronic health record (EHR) can facilitate real-time access to key health information and support improved outcomes. Many Canadian provinces use interoperable EHRs (iEHRs) to facilitate health information exchange, but the clinical use and utility of iEHRs has not been well described. OBJECTIVE: The aim of this study was to describe the use of a provincial iEHR known as the Alberta Netcare Portal (ANP) in 4 urban Alberta emergency departments. The secondary objectives were to characterize the time spent using the respective electronic tools and identify the aspects that were perceived as most useful by emergency department physicians. METHODS: In this study, we have included 4 emergency departments, 2 using paper-based ordering (University of Alberta Hospital [UAH] and Grey Nuns Community Hospital [GNCH]) and 2 using a commercial vendor clinical information system (Peter Lougheed Centre [PLC] and Foothills Medical Centre [FMC]). Structured clinical observations of ANP use and system audit logs analysis were compared at the 4 sites from October 2014 to March 2016. RESULTS: Observers followed 142 physicians for a total of 566 hours over 376 occasions. The median percentage of observed time spent using ANP was 8.5% at UAH (interquartile range, IQR, 3.7%-13.3%), 4.4% at GNCH (IQR 2.4%-4.4%), 4.6% at FMC (IQR 2.4%-7.6%), and 5.1% at PLC (IQR 3.0% 7.7%). By combining administrative and access audit data, the median number of ANP screens (ie, results and reports displayed on a screen) accessed per patient visit were 20 at UAH (IQR 6-67), 9 at GNCH (IQR 4-29), 7 at FMC (IQR 2-18), and 5 at PLC (IQR 2-14). When compared with the structured clinical observations, the statistical analysis of screen access data showed that ANP was used more at UAH than the other sites. CONCLUSIONS: This study shows that the iEHR is well utilized at the 4 sites studied, and the usage patterns implied clinical value. Use of the ANP was highest in a paper-based academic center and lower in the centers using a commercial emergency department clinical information system. More study about the clinical impacts of using iEHRs in the Canadian context including longer term impacts on quality of practice and safety are required. PMID- 30274969 TI - Social Media Users' Perception of Telemedicine and mHealth in China: Exploratory Study. AB - BACKGROUND: The use of telemedicine and mHealth has increased rapidly in the People's Republic of China. While telemedicine and mHealth have great potential, wide adoption of this technology depends on how patients, health care providers, and other stakeholders in the Chinese health sector perceive and accept the technology. OBJECTIVE: To explore this issue, we aimed to examine a social media platform with a dedicated focus on health information technology and informatics in China. Our goal is to utilize the findings to support further research. METHODS: In this exploratory study, we selected a social media platform-HC3i.cn to examine the perception of telemedicine and mHealth in China. We performed keyword analysis and analyzed the prevalence and term frequency-inverse document frequency of keywords in the selected social media platform; furthermore, we performed qualitative analysis. RESULTS: We organized the most prominent 16 keywords from 571 threads into 8 themes: (1) Question versus Answer; (2) Hospital versus Clinic; (3) Market versus Company; (4) Doctor versus Nurse; (5) Family versus Patient; (6) iPad versus Tablet; (7) System versus App; and (8) Security versus Caregiving. Social media participants perceived not only significant opportunities associated with telemedicine and mHealth but also barriers to overcome to realize these opportunities. CONCLUSIONS: We identified interesting issues in this paper by studying a social media platform in China. Among other things, participants in the selected platform raised concerns about quality and costs associated with the provision of telemedicine and mHealth, despite the new technology's great potential to address different issues in the Chinese health sector. The methods applied in this paper have some limitations, and the findings may not be generalizable. We have discussed directions for further research. PMID- 30274970 TI - Is palliative care cost-effective in low-income and middle-income countries? A mixed-methods systematic review. AB - INTRODUCTION: Of the 40 million people globally in need of palliative care (PC), just 14% receive it, predominantly in high-income countries. Within fragile health systems that lack PC, incurable illness is often marked by pain and suffering, as well as burdensome costs. In high-income settings, PC decreases healthcare utilisation, thus enhancing value. Similar cost-effectiveness models are lacking in low-income and middle-income countries and with them, the impetus and funding to expand PC delivery. METHODS: We conducted a systematic search of seven databases to gather evidence of the cost-effectiveness of PC in low-income and middle-income countries. We extracted and synthesised palliative outcomes and economic data from original research studies occurring in low-income and middle income countries. This review adheres to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and includes a quality appraisal. RESULTS: Our search identified 10 eligible papers that included palliative and economic outcomes in low-income and middle-income countries. Four provided true cost effectiveness analyses in comparing the costs of PC versus alternative care, with PC offering cost savings, favourable palliative outcomes and positive patient reported and family-reported outcomes. CONCLUSIONS: Despite the small number of included studies, wide variety of study types and lack of high-quality studies, several patterns emerged: (1) low-cost PC delivery in low-income and middle income countries is possible, (2) patient-reported outcomes are favourable and (3) PC is less costly than the alternative. This review highlights the extraordinary need for robust cost-effectiveness analysis of PC in low-income and middle-income countries in order to develop health economic models for the delivery of PC, direct resource allocation and guide healthcare policy for PC delivery in low-income and middle-income countries. PMID- 30274971 TI - Intravenous methadone in a patient with advanced cancer. AB - A patient receiving maintenance treatment with methadone (MTM) was treated with parenteral methadone for intense pain crises in cancer of the tongue with severe mucositis and dysphagia. Authors like Manfredi et al describe good results in the use of methadone as an analgesic in patients with MTM. The difficulties which arise with parenteral use derive from the drug itself and from those to whom the treatment is administered: serious side effects like malignant arrhythmias and respiratory depression and the complex nature of these patients, addicted to opiates with a terminal illness and pain which is difficult to treat. It should be administered by experts in palliative care in a healthcare unit where it can be successfully monitored. PMID- 30274974 TI - US had record flu deaths last year, says CDC. PMID- 30274975 TI - Who will the Defence and National Rehabilitation Centre rehabilitate? PMID- 30274973 TI - High Prevalence of Hereditary Cancer Syndromes and Outcomes in Adults with Early Onset Pancreatic Cancer. AB - Introduction: We aimed to determine the prevalence and landscape of germline mutations among patients with young-onset pancreatic ductal adenocarcinoma (PDAC) as well as their influence in prognosis.Methods: Patients from two cohorts were studied, the high-risk cohort (HRC), which included 584 PDAC patients who received genetic counseling at The University of Texas MD Anderson Cancer Center, and a general cohort (GC) with 233 metastatic PDAC patients. We defined germline DNA sequencing on 13 known pancreatic cancer susceptibility genes. The prevalence and landscape of mutations were determined, and clinical characteristics including survival were analyzed.Results: A total of 409 patients underwent genetic testing (277 from HRC and 132 from GC). As expected, the HRC had higher prevalence of germline mutations compared with the GC: 17.3% versus 6.81%. The most common mutations in both cohorts were in BRCA1/2 and mismatch-repair (MMR) genes. Patients younger than 60 years old had significantly higher prevalence of germline mutations in both the HRC [odds ratios (OR), 1.93 +/- 1.03-3.70, P = 0.039] and GC (4.78 +/- 1.10-32.95, P = 0.036). Furthermore, PDAC patients with germline mutations in the GC had better overall survival than patients without mutations (HR, 0.44; 95% CI of HR, 0.25-0.76, P = 0.030).Discussion: Germline mutations are highly prevalent in patients with PDAC of early onset and can be predictive of better outcomes. Considering emerging screening strategies for relatives carrying susceptibility genes as well as impact on therapy choices, genetic counseling and testing should be encouraged in PDAC patients, particularly those of young onset.

AB - BACKGROUND: Although interest in droplet-digital PCR technology (ddPCR) for cell free circulating DNA (cfDNA) analysis is burgeoning, the technology is compromised by subsampling errors and the few clinical targets that can be analyzed from limited input DNA. The paucity of starting material acts as a "glass ceiling" in liquid biopsies because, irrespective how analytically sensitive ddPCR techniques are, detection limits cannot be improved past DNA input limitations. METHODS: We applied denaturation-enhanced ddPCR (dddPCR) using fragmented genomic DNA (gDNA) with defined mutations. We then tested dddPCR on cfDNA from volunteers and patients with cancer for commonly-used mutations. gDNA and cfDNA were tested with and without end repair before denaturation and digital PCR. RESULTS: By applying complete denaturation of double-stranded DNA before ddPCR droplet formation the number of positive droplets increased. dddPCR using gDNA resulted in a 1.9-2.0-fold increase in data-positive droplets, whereas dddPCR applied on highly-fragmented cfDNA resulted in a 1.6-1.7-fold increase. End repair of cfDNA before denaturation enabled cfDNA to display a 1.9-2.0-fold increase in data-positive signals, similar to gDNA. Doubling of data-positive droplets doubled the number of potential ddPCR assays that could be conducted from a given DNA input and improved ddPCR precision for cfDNA mutation detection. CONCLUSIONS: dddPCR is a simple and useful modification in ddPCR that enables extraction of more information from low-input clinical samples with minor change in protocols. It should be applicable to all ddPCR platforms for mutation detection and, potentially, for gene copy-number analysis in cancer and prenatal screening. PMID- 30274972 TI - TET2 Deficiency Causes Germinal Center Hyperplasia, Impairs Plasma Cell Differentiation, and Promotes B-cell Lymphomagenesis. AB - : TET2 somatic mutations occur in ~10% of diffuse large B-cell lymphomas (DLBCL) but are of unknown significance. Herein, we show that TET2 is required for the humoral immune response and is a DLBCL tumor suppressor. TET2 loss of function disrupts transit of B cells through germinal centers (GC), causing GC hyperplasia, impaired class switch recombination, blockade of plasma cell differentiation, and a preneoplastic phenotype. TET2 loss was linked to focal loss of enhancer hydroxymethylation and transcriptional repression of genes that mediate GC exit, such as PRDM1. Notably, these enhancers and genes are also repressed in CREBBP-mutant DLBCLs. Accordingly, TET2 mutation in patients yields a CREBBP-mutant gene-expression signature, CREBBP and TET2 mutations are generally mutually exclusive, and hydroxymethylation loss caused by TET2 deficiency impairs enhancer H3K27 acetylation. Hence, TET2 plays a critical role in the GC reaction, and its loss of function results in lymphomagenesis through failure to activate genes linked to GC exit signals. SIGNIFICANCE: We show that TET2 is required for exit of the GC, B-cell differentiation, and is a tumor suppressor for mature B cells. Loss of TET2 phenocopies CREBBP somatic mutation. These results advocate for sequencing TET2 in patients with lymphoma and for the testing of epigenetic therapies to treat these tumors.See related commentary by Shingleton and Dave, p. 1515.This article is highlighted in the In This Issue feature, p. 1494.

PMID- 30274980 TI - Copenhagen Prospective Personalized Oncology (CoPPO) - Clinical utility of using molecular profiling to select patients to phase 1 trials. AB - PURPOSE: We evaluated the clinical benefit of tumor molecular profiling (MP) to select treatment in the phase 1 setting. EXPERIMENTAL DESIGN: Patients with advanced solid cancers and exhausted treatment options referred to a phase 1 unit were included in a prospective single-centre single-arm open-label study (NCT02290522). Tumor biopsies were obtained for comprehensive genomic analysis including whole exome sequencing (WES) and RNA sequencing. When possible, patients were treated with regimen matched to the genomic profile. Primary endpoint was progression free survival. RESULTS: From May 2013 to January 2017 a total of 591 patients were enrolled with 500 patients undergoing biopsy. Genomic profiles were obtained in 460 patients and a potential actionable target was identified in 352 (70%) of 500 biopsied patients. One hundred and one patients (20%) received matched treatment based on either gene mutations or RNA expression levels of targets available in early clinical trials or off-label treatment. Objective response according to RECIST1.1 was observed in 15/101 patients (0% CR, 15% PR) with a median PFS of 12 weeks (95% CI 9.9-14.4). CONCLUSIONS: Our study supports the feasibility of genomic profiling to select patients in the phase 1 setting and suggests that genomic matching can be beneficial for a minor subset of patients with no other treatment options. Randomized studies may validate this assumption. PMID- 30274981 TI - The Role of Angiogenesis in Hepatocellular Carcinoma. AB - Hepatocellular carcinoma (HCC) accounts for about 90% of all primary liver cancers and is the second leading cause of cancer-related deaths worldwide. The hypervascular nature of most HCC tumors underlines the importance of angiogenesis in the pathobiology of these tumors. Several angiogenic pathways have been identified as being dysregulated in HCC, suggesting they may be involved in the development and pathogenesis of HCC. These data provide practical targets for systemic treatments such as those targeting the vascular endothelial growth factor receptor and its ligand. However, the clinical relevance of other more recently identified angiogenic pathways in HCC pathogenesis or treatment remains unclear. Research into molecular profiles and validation of prognostic or predictive biomarkers will be required to identify the patient subsets most likely to experience meaningful benefit from this important class of agents.

PMID- 30274983 TI - Extended Adjuvant Therapy with Neratinib Plus Fulvestrant Blocks ER/HER2 Crosstalk and Maintains Complete Responses of ER+/HER2+ Breast Cancers: Implications to the ExteNET Trial. AB - Purpose: The phase III ExteNET trial showed improved invasive disease-free survival in patients with HER2+ breast cancer treated with neratinib versus placebo after trastuzumab-based adjuvant therapy. The benefit from neratinib appeared to be greater in patients with ER+/HER2+ tumors. We thus sought to discover mechanisms that may explain the benefit from extended adjuvant therapy with neratinib.Experimental Design: Mice with established ER+/HER2+ MDA-MB-361 tumors were treated with paclitaxel plus trastuzumab +/- pertuzumab for 4 weeks, and then randomized to fulvestrant +/- neratinib treatment. The benefit from neratinib was evaluated by performing gene expression analysis for 196 ER targets, ER transcriptional reporter assays, and cell-cycle analyses.Results: Mice receiving "extended adjuvant" therapy with fulvestrant/neratinib maintained a complete response, whereas those treated with fulvestrant relapsed rapidly. In three ER+/HER2+ cell lines (MDA-MB-361, BT-474, UACC-893) but not in ER+/HER2- MCF7 cells, treatment with neratinib induced ER reporter transcriptional activity, whereas treatment with fulvestrant resulted in increased HER2 and EGFR phosphorylation, suggesting compensatory reciprocal crosstalk between the ER and ERBB RTK pathways. ER transcriptional reporter assays, gene expression, and immunoblot analyses showed that treatment with neratinib/fulvestrant, but not fulvestrant, potently inhibited growth and downregulated ER reporter activity, P AKT, P-ERK, and cyclin D1 levels. Finally, similar to neratinib, genetic and pharmacologic inactivation of cyclin D1 enhanced fulvestrant action against ER+/HER2+ breast cancer cells.Conclusions: These data suggest that ER blockade leads to reactivation of ERBB RTKs and thus extended ERBB blockade is necessary to achieve durable clinical outcomes in patients with ER+/HER2+ breast cancer.

PMID- 30274982 TI - Proteogenomic Characterization of Patient-Derived Xenografts Highlights the Role of REST in Neuroendocrine Differentiation of Castration-Resistant Prostate Cancer. AB - Background: An increasing number of castration-resistant prostate cancer (CRPC) tumors exhibit neuroendocrine (NE) features. NE prostate cancer (NEPC) has poor prognosis, and its development is poorly understood.Experimental Design: We applied mass spectrometry-based proteomics to a unique set of 17 prostate cancer patient-derived xenografts (PDX) to characterize the effects of castration in vivo, and the proteome differences between NEPC and prostate adenocarcinomas. Genome-wide profiling of REST-occupied regions in prostate cancer cells was correlated to the expression changes in vivo to investigate the role of the transcriptional repressor REST in castration-induced NEPC differentiation.Results: An average of 4,881 proteins were identified and quantified from each PDX. Proteins related to neurogenesis, cell-cycle regulation, and DNA repair were found upregulated and elevated in NEPC, while the reduced levels of proteins involved in mitochondrial functions suggested a prevalent glycolytic metabolism of NEPC tumors. Integration of the REST chromatin bound regions with expression changes indicated a direct role of REST in regulating neuronal gene expression in prostate cancer cells. Mechanistically, depletion of REST led to cell-cycle arrest in G1, which could be rescued by p53 knockdown. Finally, the expression of the REST-regulated gene secretagogin (SCGN) correlated with an increased risk of suffering disease relapse after radical prostatectomy.Conclusions: This study presents the first deep characterization of the proteome of NEPC and suggests that concomitant inhibition of REST and the p53 pathway would promote NEPC. We also identify SCGN as a novel prognostic marker in prostate cancer. Clin Cancer Res; 1-14. (c)2018 AACR. PMID- 30274984 TI - Targeting Resistance against the MDM2 Inhibitor RG7388 in Glioblastoma Cells by the MEK Inhibitor Trametinib. AB - Purpose: Resistance is an obstacle of glioma therapy. Despite targeted interventions, tumors harbor primary resistance or become resistant over short course of treatment. This study examined the mouse double minute 2 (MDM2) inhibitor RG7388 together with radiotherapy and analyzed strategies to overcome acquired MDM2 inhibitor resistance in glioblastoma.Experimental Design: Effects of RG7388 and radiotherapy were analyzed in p53 wild-type glioblastoma cell lines and glioma-initiating cells. RG7388 resistant cells were generated by increasing RG7388 doses over 3 months. Regulated pathways were investigated by microarray, qRT-PCR, and immunoblot analysis and specifically inhibited to evaluate rational salvage therapies at RG7388 resistance. Effects of RG7388 and trametinib treatment were challenged in an orthotopical mouse model with RG7388 resistant U87MG glioblastoma cells.Results: MDM2 inhibition required functional p53 and showed synergistic activity with radiotherapy in first-line treatment. Long-term exposure to RG7388 induced resistance by activation of the extracellular signal regulated kinases 1/2 (ERK1/2)-insulin growth factor binding protein 1 (IGFBP1) signaling cascade, which was specifically overcome by ERK1/2 pathway inhibition with trametinib and knockdown of IGFBP1. Combining trametinib with continued RG7388 treatment enhanced antitumor effects at RG7388 resistance in vitro and in vivo Conclusions: These data provide a rationale for combining RG7388 and radiotherapy as first-line therapy with a specific relevance for tumors insensitive to alkylating standard chemotherapy and for the addition of trametinib to continued RG7388 treatment as salvage therapy after acquired resistance against RG7388 for clinical practice.

PMID- 30274985 TI - Robust Activity of Avapritinib, Potent and Highly Selective Inhibitor of Mutated KIT, in Patient-derived Xenograft Models of Gastrointestinal Stromal Tumors. AB - Purpose: Gastrointestinal stromal tumors (GIST) are commonly treated with tyrosine kinase inhibitors (TKI). The majority of patients with advanced GIST ultimately become resistant to TKI due to acquisition of secondary KIT mutations, whereas primary resistance is mainly caused by PDGFRA p.D842V mutation. We tested the activity of avapritinib, a potent and highly selective inhibitor of mutated KIT and PDGFRA, in three patient-derived xenograft (PDX) GIST models carrying different KIT mutations, with differential sensitivity to standard TKI.Experimental Design: NMRI nu/nu mice (n = 93) were transplanted with human GIST xenografts with KIT exon 11+17 (UZLX-GIST9 KIT 11+17 ), exon 11 (UZLX-GIST3 KIT 11 ), or exon 9 (UZLX-GIST2B KIT9 ) mutations, respectively. We compared avapritinib (10 and 30 mg/kg/once daily) versus vehicle, imatinib (50 mg/kg/bid) or regorafenib (30 mg/kg/once daily; UZLX-GIST9 KIT11+17 ); avapritinib (10, 30, 100 mg/kg/once daily) versus vehicle or imatinib [UZLX-GIST3 KIT11 ]; and avapritinib (10, 30, 60 mg/kg/once daily) versus vehicle, imatinib (50, 100 mg/kg/twice daily), or sunitinib (40 mg/kg/once daily; UZLX-GIST2B KIT9 ).Results: In all models, avapritinib resulted in reduction of tumor volume, significant inhibition of proliferation, and reduced KIT signaling. In two models, avapritinib led to remarkable histologic responses, increase in apoptosis, and inhibition of MAPK-phosphorylation. Avapritinib showed superior (UZLX-GIST9 KIT 11+17 and -GIST2B KIT 9 ) or equal (UZLX-GIST3 KIT 11 ) antitumor activity to the standard dose of imatinib. In UZLX-GIST9 KIT 11+17 , the antitumor effects of avapritinib were significantly better than with imatinib or regorafenib.Conclusions: Avapritinib has significant antitumor activity in GIST PDX models characterized by different KIT mutations and sensitivity to established TKI. These data provide strong support for the ongoing clinical trials with avapritinib in patients with GIST (NCT02508532, NCT03465722). Clin Cancer Res; 1-10. (c)2018 AACR. PMID- 30274987 TI - Static stability predicts the continuum of interleg coordination patterns in Drosophila. AB - During walking, insects must coordinate the movements of their six legs for efficient locomotion. This interleg coordination is speed dependent: fast walking in insects is associated with tripod coordination patterns, whereas slow walking is associated with more variable, tetrapod-like patterns. To date, however, there has been no comprehensive explanation as to why these speed-dependent shifts in interleg coordination should occur in insects. Tripod coordination would be sufficient at low walking speeds. The fact that insects use a different interleg coordination pattern at lower speeds suggests that it is more optimal or advantageous at these speeds. Furthermore, previous studies focused on discrete tripod and tetrapod coordination patterns. Experimental data, however, suggest that changes observed in interleg coordination are part of a speed-dependent spectrum. Here, we explore these issues in relation to static stability as an important aspect for interleg coordination in Drosophila We created a model that uses basic experimentally measured parameters in fruit flies to find the interleg phase relationships that maximize stability for a given walking speed. The model predicted a continuum of interleg coordination patterns spanning the complete range of walking speeds as well as an anteriorly directed swing phase progression. Furthermore, for low walking speeds, the model predicted tetrapod like patterns to be most stable, whereas at high walking speeds, tripod coordination emerged as most optimal. Finally, we validated the basic assumption of a continuum of interleg coordination patterns in a large set of experimental data from walking fruit flies and compared these data with the model-based predictions.

AB - OBJECTIVE: Aim of this paper is to evaluate the outcomes of 'idiopathic' chronic large pericardial effusions without initial evidence of pericarditis. METHODS: All consecutive cases of idiopathic chronic large pericardial effusions evaluated from 2000 to 2015 in three Italian tertiary referral centres for pericardial diseases were enrolled in a prospective cohort study. The term 'idiopathic' was applied to cases that performed a complete diagnostic evaluation to exclude a specific aetiology. A clinical and echocardiographic follow-up was performed every 3-6 months. RESULTS: 100 patients were included (mean age 61.3+/-14.6 years, 54 females, 44 patients were asymptomatic according to clinical evaluation) with a mean follow-up of 50 months. The baseline median size of the effusion (evaluated as the largest end-diastolic echo-free space) was 25 mm (IQR 8) and decreased to a mean value of 7 mm (IQR 19; p<0.0001) with complete regression in 39 patients at the end of follow-up. There were no new aetiological diagnoses. Adverse events were respectively: cardiac tamponade in 8 patients (8.0%), pericardiocentesis in 30 patients (30.0%), pericardial window in 12 cases (12.0%) and pericardiectomy in 3 patients (3.0%). Recurrence-free survival and complications-free survival was better in patients treated without interventions (log rank p=0.0038). CONCLUSIONS: The evolution of 'idiopathic' chronic large pericardial effusions is usually benign with reduction of the size of the effusion in the majority of cases, and regression in about 40% of cases. The risk of cardiac tamponade is 2.2%/year and recurrence/complications survival was better in patients treated conservatively without interventions. PMID- 30274989 TI - Replicability of Introgression Under Linked, Polygenic Selection. AB - We study how a block of genome with a large number of weakly selected loci introgresses under directional selection into a genetically homogeneous population. We derive exact expressions for the expected rate of growth of any fragment of the introduced block during the initial phase of introgression, and show that the growth rate of a single-locus variant is largely insensitive to its own additive effect, but depends instead on the combined effect of all loci within a characteristic linkage scale. The expected growth rate of a fragment is highly correlated with its long-term introgression probability in populations of moderate size, and can hence identify variants that are likely to introgress across replicate populations. We clarify how the introgression probability of an individual variant is determined by the interplay between hitchhiking with relatively large fragments during the early phase of introgression and selection on fine-scale variation within these, which at longer times results in differential introgression probabilities for beneficial and deleterious loci within successful fragments. By simulating individuals, we also investigate how introgression probabilities at individual loci depend on the variance of fitness effects, the net fitness of the introduced block, and the size of the recipient population, and how this shapes the net advance under selection. Our work suggests that even highly replicable substitutions may be associated with a range of selective effects, which makes it challenging to fine map the causal loci that underlie polygenic adaptation. PMID- 30274988 TI - BMP Signaling Determines Body Size via Transcriptional Regulation of Collagen Genes in Caenorhabditis elegans. AB - Body size is a tightly regulated phenotype in metazoans that depends on both intrinsic and extrinsic factors. While signaling pathways are known to control organ and body size, the downstream effectors that mediate their effects remain poorly understood. In the nematode Caenorhabditis elegans, a Bone Morphogenetic Protein (BMP)-related signaling pathway is the major regulator of growth and body size. We investigated the transcriptional network through which the BMP pathway regulates body size and identified cuticle collagen genes as major effectors of growth control. We demonstrate that cuticle collagens can act as positive regulators (col-41), negative regulators (col-141), or dose-sensitive regulators (rol-6) of body size. Moreover, we find a requirement of BMP signaling for stage specific expression of cuticle collagen genes. We show that the Smad signal transducers directly bind conserved Smad-binding elements in regulatory regions of col-141 and col-142, but not of col-41 Hence, cuticle collagen genes may be directly and indirectly regulated via the BMP pathway. Our work thus connects a conserved signaling pathway with its critical downstream effectors, advancing insight into how body size is specified. Since collagen mutations and misregulation are implicated in numerous human genetic disorders and injury sequelae, understanding how collagen gene expression is regulated has broad implications.

PMID- 30274992 TI - Influence of socioeconomic events on cause-specific mortality in urban Shanghai, China, from 1974 to 2015: a population-based longitudinal study. AB - BACKGROUND: Understanding how socioeconomic events influence cause-specific mortality is essential for optimizing disease-control strategies. We characterized long-term trends in cause-specific mortality in a stable population from a very large urban centre. METHODS: We derived population data from 1974 to 2015 on vital status, demographics and causes of death from the death registration system in Yangpu District, Shanghai, China. We examined temporal trends in mortality and assessed the effects of age, period and birth cohort. RESULTS: Over 41 879 864 person-years of follow-up, we analyzed 290 332 deaths: 3.80% from communicable conditions (group 1), 86.50% from noncommunicable diseases (group 2), and 5.56% from injuries (group 3). Age-standardized mortality decreased after 1988 for group 1 (average annual percentage change [AAPC] -6.7, 95% confidence interval [CI] -9.3 to -4.1), after 1995 for group 2 (AAPC -2.9, 95% CI -3.5 to -2.3), and after 1994 for group 3 (AAPC -5.4, 95% CI -6.3 to 4.5), after improvements in public health and clinical service infrastructure and the removal of polluting industries during the 1980s. We observed increased mortality from group 2 and group 3 causes in those born between 1955 and 1965, a period that included the Great Chinese Famine. Cause-specific mortality risks increased in those born after 1949 for cancer and diabetes only. INTERPRETATION: Birth cohorts exposed to extreme starvation in early life had increased premature cause-specific mortality in later life. Decreased cause-specific mortality followed improvements in public health, medical infrastructure and pollution control, but not for cancer or diabetes, likely because of exposure to new risk factors.

PMID- 30275001 TI - Combination of exome sequencing and immune testing confirms Aicardi-Goutieres syndrome type 5 in a challenging pediatric neurology case. AB - Exome sequencing is increasingly being used to help diagnose pediatric neurology cases when clinical presentations are not specific. However, interpretation of equivocal results that include variants of uncertain significance remains a challenge. In those cases, follow-up testing and clinical correlation can help clarify the clinical relevance of the molecular findings. In this report, we describe the diagnostic odyssey of a 4-year-old girl who presented with global developmental delay and seizures, with leukodystrophy seen on MRI. Clinical evaluation, MRI, and comprehensive metabolic testing were performed, followed by whole-exome sequencing (WES), parental testing, follow-up testing, and retrospective detailed clinical evaluation. WES identified two candidate causative pathogenic variants in SAMHD1, a gene associated with the recessive condition Aicardi-Goutieres syndrome (AGS) type 5 (OMIM 612952): a previously reported pathogenic variant NM_015474 c.602T>A (p.I201N), maternally inherited, and a rare missense variant of uncertain significance, c.1293A>T(p.L431F). Analysis of type I interferon-related biomarkers demonstrated that the patient has an interferon signature characteristic of AGS. Retrospective detailed clinical evaluation showed that the girl has a phenotype consistent with AGS5, a rare neurological condition. These results further define the phenotypic spectrum associated with specific SAMHD1 variants, including heterozygous variants in AGS carriers, and support the idea that autoinflammatory dysregulation is part of the disease pathophysiology. More broadly, this work highlights the issues and methodology involved in ascribing clinical relevance to interpretation of variants detected by WES. PMID- 30275002 TI - Multimodal molecular analysis of an atypical small cell carcinoma of the ovary, hypercalcemic type. AB - A 12-yr-old normocalcemic female treated for a ruptured ovarian juvenile granulosa cell tumor at an outside hospital presented for exploratory laparotomy and gross surgical debulking of pelvic recurrence. Morphologically, the tumor was composed of sheets and nests of small blue cells forming cysts of various sizes and focal mucinous differentiation. Epithelial membrane antigen (EMA), patchy inhibin, and strong and diffuse p53 immunoreactivity were also observed. A revised diagnosis of mixed sex cord stromal tumor with heterologous elements was favored because of the inhibin immunoreactivity. Targeted next-generation sequencing of the tumor revealed a SMARCA4 c.1141C>T, p.Arg381Ter (NM_001128849.1) nonsense mutation and an in-frame 18-bp TP53 deletion (c.594_611del18, p.Gly199_Glu204del, NM_001126112.2). Cytogenetic analysis revealed a normal 46,XX karyotype, and OncoScan single-nucleotide polymorphism array analysis demonstrated copy-neutral loss of heterozygosity (CN-LOH) of 19p13.3-19p13.2 and mosaic CN-LOH of 17p13.3-p11.2 encompassing the SMARCA4 and TP53 loci, respectively. Subsequent germline SMARCA4 sequencing confirmed a heterozygous SMARCA4 p.Arg381Ter mutation. In lieu of the molecular findings, the diagnosis was amended to small cell carcinoma of the ovary, hypercalcemic type (SCCOHT). The patient was treated aggressively with paclitaxel, carboplatin, and bevacizumab. She received an autologous stem cell transplant but died 5 mo after SCCOHT diagnosis secondary to complications of the transplant. This case expands the morphologic, immunophenotypic, and genomic spectrum of SCCOHT and highlights how multimodal molecular analysis can assist with the diagnosis and clinical management of SCCOHT patients. PMID- 30275003 TI - Whole-exome sequencing enables correct diagnosis and surgical management of rare inherited childhood anemia. AB - Correct diagnosis of inherited bone marrow failure syndromes is a challenge because of the significant overlap in clinical presentation of these disorders. Establishing right genetic diagnosis is crucial for patients' optimal clinical management and family counseling. A nondysmorphic infant reported here developed severe transfusion-dependent anemia and met clinical criteria for diagnosis of Diamond-Blackfan anemia (DBA). However, whole-exome sequencing demonstrated that the child was a compound heterozygote for a paternally inherited pathogenic truncating variant (SPTA1 c.4975 C>T) and a novel maternally inherited missense variant of uncertain significance (SPTA1 c.5029 G>A) within the spectrin gene, consistent with hereditary hemolytic anemia due to disruption of red blood cell (RBC) cytoskeleton. Ektacytometry demonstrated abnormal membrane flexibility of the child's RBCs. Scanning electron microscopy revealed morphological aberrations of the patient's RBCs. Both parents were found to have mild hereditary elliptocytosis. Importantly, patients with severe RBC membrane defects may be successfully managed with splenectomy to minimize peripheral destruction of misshapen RBCs, whereas patients with DBA require lifelong transfusions, steroid therapy, or hematopoietic stem cell transplantation. As suggested by the WES findings, splenectomy rendered our patient transfusion-independent, improving the family's quality of life and preventing transfusion-related iron overload. This case illustrates the utility of whole-exome sequencing in clinical care of children with genetic disorders of unclear presentation. PMID- 30275004 TI - Biallelic variants in VARS in a family with two siblings with intellectual disability and microcephaly: case report and review of the literature. AB - Two male siblings ages 15 and 10 yr old had similar features of intellectual disability, developmental delay, severe speech impairment, microcephaly, prematurity, and transient elevation of liver enzymes in infancy. Exome sequencing revealed one novel (c.65C>A; p.Ala22Asp) and one ultra-rare (c.3214T>C; p.Phe1072Leu) predicted damaging missense variant in trans in the gene encoding cytoplasmic valyl-tRNA synthetase (VARS). Biallelic variants in VARS have previously been associated with a neurodevelopmental disorder characterized by microcephaly, seizures, and cortical atrophy (NDMSCA; MIM #617802). Although our patients have no history of seizures or cortical atrophy, we suggest that the biallelic variants in VARS p.Ala22Asp and p.Phe1072Leu in this family are likely pathogenic and associated with NDMSCA, expanding the clinical phenotype of the condition.

PMID- 30275006 TI - Risk of psychiatric disorders in overactive bladder syndrome: a nationwide cohort study in Taiwan. AB - Population-based cohort study investigating the risk of depression and other psychiatric disorders for patients with overactive bladder (OAB) syndrome is unavailable. This study investigated the subsequent risk of psychiatric disorders among patients with OAB in an Asian population. Using data from the National Health Insurance Research Database of Taiwan, we established a cohort with 811 patients in an exposed group with OAB between January 1, 2000 and December 31, 2000, and a non-exposed group, without OAB, of 2433 patients without OAB matched by age and year of diagnosis. The occurrence of psychiatric disorders and Cox regression model measured adjusted HRs (aHR) were monitored until the end of 2013. The overall incidence of psychiatric disorders was 41.7% higher in the exposed group with OAB than in the non-exposed group without OAB (14.2% vs 10.1%, p<0.001), with an aHR of 1.34 (95% CI 1.12 to 1.80, p<0.001) for the OAB cohort. OAB was associated with the increased risk of dementia, anxiety, depressive, sleep, and psychotic disorders, with aHRs as 1.53 (p=0.040), 1.61 (p<0.001), 2.10 (p<0.001), 1.43 (p<0.001), and 2.49 (p=0.002), respectively. The risk of psychiatric disorders, including depression and anxiety, is significantly higher in patients with OAB than in those without OAB. Evaluation of psychiatric status in patients with OAB is strongly recommended. PMID- 30275007 TI - KDM6B overexpression activates innate immune signaling and impairs hematopoiesis in mice. AB - KDM6B is an epigenetic regulator that mediates transcriptional activation during differentiation, including in bone marrow (BM) hematopoietic stem and progenitor cells (HSPCs). Overexpression of KDM6B has been reported in BM HSPCs of patients with myelodysplastic syndromes (MDS) and chronic myelomonocytic leukemia (CMML). Whether the overexpression of KDM6B contributes to the pathogenesis of these diseases remains to be elucidated. To study this, we generated a Vav-KDM6B mouse model, which overexpresses KDM6B in the hematopoietic compartment. KDM6B overexpression alone led to mild hematopoietic phenotype, and chronic innate immune stimulation of Vav-KDM6B mice with the Toll-like receptor (TLR) ligand lipopolysaccharide (LPS) resulted in significant hematopoietic defects. These defects recapitulated features of MDS and CMML, including leukopenia, dysplasia, and compromised repopulating function of BM HSPCs. Transcriptome studies indicated that KDM6B overexpression alone could lead to activation of disease relevant genes such as S100a9 in BM HSPCs, and when combined with innate immune stimulation, KDM6B overexpression resulted in more profound overexpression of innate immune and disease-relevant genes, indicating that KDM6B was involved in the activation of innate immune signaling in BM HSPCs. Finally, pharmacologic inhibition of KDM6B with the small molecule inhibitor GSK-J4 ameliorated the ineffective hematopoiesis observed in Vav-KDM6B mice. This effect was also observed when GSK-J4 was applied to the primary BM HSPCs of patients with MDS by improving their repopulating function. These results indicate that overexpression of KDM6B mediates activation of innate immune signals and has a role in MDS and CMML pathogenesis, and that KDM6B targeting has therapeutic potential in these myeloid disorders. PMID- 30275008 TI - Tracking Anti-Staphylococcus aureus Antibodies Produced In Vivo and Ex Vivo during Foot Salvage Therapy for Diabetic Foot Infections Reveals Prognostic Insights and Evidence of Diversified Humoral Immunity. AB - Management of foot salvage therapy (FST) for diabetic foot infections (DFI) is challenging due to the absence of reliable diagnostics to identify the etiologic agent and prognostics to justify aggressive treatments. As Staphylococcus aureus is the most common pathogen associated with DFI, we aimed to develop a multiplex immunoassay of IgG in serum and medium enriched for newly synthesized anti-S. aureus antibodies (MENSA) generated from cultured peripheral blood mononuclear cells of DFI patients undergoing FST. Wound samples were collected from 26 DFI patients to identify the infecting bacterial species via 16S rRNA sequencing. Blood was obtained over 12 weeks of FST to assess anti-S. aureus IgG levels in sera and MENSA. The results showed that 17 out of 26 infections were polymicrobial and 12 were positive for S. aureus While antibody titers in serum and MENSA displayed similar diagnostic potentials to detect S. aureus infection, MENSA showed a 2-fold-greater signal-to-background ratio. Multivariate analyses revealed increases in predictive power of diagnosing S. aureus infections (area under the receiver operating characteristic curve [AUC] > 0.85) only when combining titers against different classes of antigens, suggesting cross functional antigenic diversity. Anti-S. aureus IgG levels in MENSA decreased with successful FST and rose with reinfection. In contrast, IgG levels in serum remained unchanged throughout the 12-week FST. Collectively, these results demonstrate the applicability of serum and MENSA for diagnosis of S. aureus DFI with increased power by combining functionally distinct titers. We also found that tracking MENSA has prognostic potential to guide clinical decisions during FST. PMID- 30275009 TI - Cross Talk between MarR-Like Transcription Factors Coordinates the Regulation of Motility in Uropathogenic Escherichia coli. AB - The MarR-like protein PapX represses the transcription of the flagellar master regulator genes flhDC in uropathogenic Escherichia coli (UPEC), the primary cause of uncomplicated urinary tract infections (UTIs). PapX is encoded by the pap operon, which also encodes the adherence factors termed P fimbriae. Both adherence and motility are critical for productive colonization of the urinary tract. However, the mechanisms involved in coordinating the transition between adherence and motility are not well characterized. UPEC strain CFT073 carries both papX and a homolog, focX, located in the foc operon encoding F1C fimbriae. In this study, we characterized the dose effects of "X" genes on flagellar gene expression and cross talk between focX and papX We found that both FocX and PapX repress flhD transcription. However, we determined that the DeltapapX mutant was hypermotile, while the loss of focX did not affect motility. We further investigated this phenotype and found that FocX functions as a repressor of papX Additionally, we identified a proximal independent promoter upstream of both focX and papX and assessed the expression of focX and papX during culture in human urine and on LB agar plates compared to LB medium. Finally, we characterized the contributions of PapX and FocX to fitness in the ascending murine model of UTI and observed a subtle, but not statistically significant, fitness defect in colonization of the kidneys. Altogether, these results expand our understanding of the impact of carrying multiple X genes on the coordinated regulation of motility and adherence in UPEC. PMID- 30275011 TI - Polymorphisms in receptors involved in opsonic and non-opsonic phagocytosis and the risk of infection in oncohematological patients. AB - High-risk hematologic malignancies are a privileged setting for infection by opportunistic microbes, invasive mycoses being one of the most serious complications. Recently, the genetic background has emerged as an unanticipated risk factor. For this reason, polymorphisms for genes encoding archetypal receptors involved in the opsonic and non-opsonic clearance of microbes, pentraxin-3, and Dectin-1, respectively, were studied and correlated with the risk of infection. Fungal, bacterial, and viral infections were registered in a group of 198 patients with high-risk hematologic malignancies. Polymorphisms for pentraxin-3 gene (PTX3) showed a significant association with the risk of fungal infection by Candida spp and, especially, by Aspergillus spp. This link remained even in patients undergoing antifungal prophylaxis, thus demonstrating the clinical relevance of PTX3 in the defense against fungi. CLEC7A polymorphisms did not show any definite correlation with the risk of invasive mycosis nor did they influence the expression of Dectin-1 isoforms generated by alternative splicing. PTX3 mRNA expression was significantly lower in samples from healthy volunteers who showed the polymorphisms, although not differences were observed in the extent of the induction elicited by bacterial lipopolysaccharide and heat-killed C. albicans, thus suggesting that the expression of PTX3 at the start of infection may influence the clinical outcome. PTX3 mRNA expression can be a good biomarker to establish proper antifungal prophylaxis in immunodepressed patients. PMID- 30275010 TI - Deletion of Interleukin-4 Receptor Alpha-Responsive Keratinocytes in BALB/c Mice Does Not Alter Susceptibility to Cutaneous Leishmaniasis. AB - The skin microenvironment at the site of infection plays a role in the early events that determine protective T helper 1/type 1 immune responses during cutaneous leishmaniasis (CL) infection. During CL in nonhealing BALB/c mice, early interleukin-4 (IL-4) can instruct dendritic cells for protective Th1 immunity. Additionally, keratinocytes, which are the principal cell type in the skin epidermis, have been shown to secrete IL-4 early after Leishmania major infection. Here, we investigated whether IL-4/IL-13 signaling via the common IL-4 receptor alpha chain (IL-4Ralpha) on keratinocytes contributes to susceptibility during experimental CL. To address this, keratinocyte-specific IL-4Ralpha deficient (KRT14cre IL-4Ralpha-/lox) mice on a BALB/c genetic background were generated by gene targeting and site-specific recombination (Cre/loxP) under the control of the keratinocyte-specific krt14 locus. Following high-dose infection with L. major IL-81 and LV39 promastigotes subcutaneously in the footpad, footpad swelling, parasite burden, IFN-gamma/IL-4/IL-13 cytokine production, and type 1 and type 2 antibody responses were similar between KRT14cre IL-4Ralpha-/lox and littermate control IL-4Ralpha-/lox BALB/c mice. An intradermal infection with low dose L. major IL-81 and LV39 promastigotes in the ear showed results in infected KRT14cre IL-4Ralpha-/lox BALB/c mice similar to those of littermate control IL 4Ralpha-/lox BALB/c mice, with the exception of a significant decrease observed in parasite burden only at the site of LV39 infection in the ear. Collectively, our results show that autocrine and paracrine signaling of IL-4/IL-13 through the IL-4Ralpha chain on keratinocytes does not influence the establishment of a nonhealing Th2 immune response in BALB/c mice during L. major infection. PMID- 30275012 TI - The S-layer protein of a Clostridium difficile SLCT-11 strain displays a complex glycan required for normal cell growth and morphology. AB - Clostridium difficile is a bacterial pathogen that causes major health challenges worldwide. It has a well-characterized surface (S)-layer, a para-crystalline proteinaceous layer surrounding the cell wall. In many bacterial and archaeal species, the S-layer is glycosylated, but no such modifications have been demonstrated in C. difficile. Here, we show that a C. difficile strain of S-layer cassette type 11, Ox247, has a complex glycan attached via an O-linkage to Thr-38 of the S-layer low-molecular-weight subunit. Using MS and NMR, we fully characterized this glycan. We present evidence that it is composed of three domains: (i) a core peptide-linked tetrasaccharide with the sequence -4-alpha-Rha 3-alpha-Rha-3-alpha-Rha-3-beta-Gal-peptide; (ii) a repeating pentasaccharide with the sequence -4-beta-Rha-4-alpha-Glc-3-beta-Rha-4-(alpha-Rib-3-)beta-Rha-; and (iii) a nonreducing end-terminal 2,3 cyclophosphoryl-rhamnose attached to a ribose-branched sub-terminal rhamnose residue. The Ox247 genome contains a 24-kb locus containing genes for synthesis and protein attachment of this glycan. Mutations in genes within this locus altered or completely abrogated formation of this glycan, and their phenotypes suggested that this S-layer modification may affect sporulation, cell length, and biofilm formation of C. difficile In summary, our findings indicate that the S-layer protein of SLCT-11 strains displays a complex glycan and suggest that this glycan is required for C. difficile sporulation and control of cell shape, a discovery with implications for the development of antimicrobials targeting the S-layer. PMID- 30275013 TI - Synergistic effects of functionally distinct substitutions in beta-lactamase variants shed light on the evolution of bacterial drug resistance. AB - The CTX-M beta-lactamases have emerged as the most widespread extended-spectrum beta-lactamases (ESBLs) in Gram-negative bacteria. These enzymes rapidly hydrolyze cefotaxime, but not the related cephalosporin, ceftazidime. ESBL variants have evolved, however, that provide enhanced ceftazidime resistance. We show here that a natural variant at a nonactive site, i.e. second-shell residue N106S, enhances enzyme stability but reduces catalytic efficiency for cefotaxime and ceftazidime and decreases resistance levels. However, when the N106S variant was combined with an active-site variant, D240G, that enhances enzyme catalytic efficiency, but decreases stability, the resultant double mutant exhibited higher resistance levels than predicted on the basis of the phenotypes of each variant. We found that this epistasis is due to compensatory effects, whereby increased stability provided by N106S overrides its cost of decreased catalytic activity. X ray structures of the variant enzymes in complex with cefotaxime revealed conformational changes in the active-site loop spanning residues 103-106 that were caused by the N106S substitution and relieve steric strain to stabilize the enzyme, but also alter contacts with cefotaxime and thereby reduce catalytic activity. We noted that the 103-106 loop conformation in the N106S-containing variants is different from that of WT CTX-M but nearly identical to that of the non-ESBL, TEM-1 beta-lactamase, having a serine at the 106 position. Therefore, residue 106 may serve as a "switch" that toggles the conformations of the 103-106 loop. When it is serine, the loop is in the non-ESBL, TEM-like conformation, and when it is asparagine, the loop is in a CTX-M-like, cefotaximase-favorable conformation. PMID- 30275016 TI - Structural attributes of mammalian prion infectivity: Insights from studies with synthetic prions. AB - Prion diseases are neurodegenerative disorders that affect many mammalian species. Mammalian prion proteins (PrPs) can misfold into many different aggregates. However, only a small subpopulation of these structures is infectious. One of the major unresolved questions in prion research is identifying which specific structural features of these misfolded protein aggregates are important for prion infectivity in vivo Previously, two types of proteinase K-resistant, self-propagating aggregates were generated from the recombinant mouse prion protein in the presence of identical cofactors. Although these two aggregates appear biochemically very similar, they have dramatically different biological properties, with one of them being highly infectious and the other one lacking any infectivity. Here, we used several MS-based structural methods, including hydrogen-deuterium exchange and hydroxyl radical footprinting, to gain insight into the nature of structural differences between these two PrP aggregate types. Our experiments revealed a number of specific differences in the structure of infectious and noninfectious aggregates, both at the level of the polypeptide backbone and quaternary packing arrangement. In particular, we observed that a high degree of order and stability of beta-sheet structure within the entire region between residues ~89 and 227 is a primary attribute of infectious PrP aggregates examined in this study. By contrast, noninfectious PrP aggregates are characterized by markedly less ordered structure up to residue ~167. The structural constraints reported here should facilitate development of experimentally based high-resolution structural models of infectiosus mammalian prions. PMID- 30275015 TI - Codon usage regulates human KRAS expression at both transcriptional and translational levels. AB - KRAS and HRAS are highly homologous oncogenic Ras GTPase family members that are mutated in a wide spectrum of human cancers. Despite having high amino acid identity, KRAS and HRAS have very different codon usage biases: the HRAS gene contains many common codons, and KRAS is enriched for rare codons. Rare codons in KRAS suppress its protein expression, which has been shown to affect both normal and cancer biology in mammals. Here, using HRAS or KRAS expression in different human cell lines and in vitro transcription and translation assays, we show that KRAS rare codons inhibit both translation efficiency and transcription and that the contribution of these two processes varies among different cell lines. We observed that codon usage regulates mRNA translation efficiency such that WT KRAS mRNA is poorly translated. On the other hand, common codons increased transcriptional rates by promoting activating histone modifications and recruitment of transcriptional coactivators. Finally, we found that codon usage also influences KRAS protein conformation, likely because of its effect on co translational protein folding. Together, our results reveal that codon usage has multidimensional effects on protein expression, ranging from effects on transcription to protein folding in human cells. PMID- 30275014 TI - The N-peptide-binding mode is critical to Munc18-1 function in synaptic exocytosis. AB - Sec1/Munc18 (SM) proteins promote intracellular vesicle fusion by binding to N ethylmaleimide-sensitive factor attachment protein receptors (SNAREs). A key SNARE-binding mode of SM proteins involves the N-terminal peptide (N-peptide) motif of syntaxin, a SNARE subunit localized to the target membrane. In in vitro membrane fusion assays, inhibition of N-peptide motif binding previously has been shown to abrogate the stimulatory function of Munc18-1, a SM protein involved in synaptic exocytosis in neurons. The physiological role of the N-peptide-binding mode, however, remains unclear. In this work, we addressed this key question using a "clogged" Munc18-1 protein, in which an ectopic copy of the syntaxin N peptide motif was directly fused to Munc18-1. We found that the ectopic N-peptide motif blocks the N-peptide-binding pocket of Munc18-1, preventing the latter from binding to the native N-peptide motif on syntaxin-1. In a reconstituted system, we observed that clogged Munc18-1 is defective in promoting SNARE zippering. When introduced into induced neuronal cells (iN cells) derived from human pluripotent stem cells, clogged Munc18-1 failed to mediate synaptic exocytosis. As a result, both spontaneous and evoked synaptic transmission was abolished. These genetic findings provide direct evidence for the crucial role of the N-peptide-binding mode of Munc18-1 in synaptic exocytosis. We suggest that clogged SM proteins will also be instrumental in defining the physiological roles of the N-peptide-binding mode in other vesicle-fusion pathways.

Because of its central role in metabolism, FXR represents an important drug target to manage metabolic and other diseases, such as primary biliary cirrhosis and nonalcoholic steatohepatitis. FXR and nuclear receptor retinoid X receptor alpha (RXRalpha) form a heterodimer that controls the expression of numerous downstream genes. To date, the structural basis and functional consequences of the FXR/RXR heterodimer interaction have remained unclear. Herein, we present the crystal structures of the heterodimeric complex formed between the ligand-binding domains of human FXR and RXRalpha. We show that both FXR and RXR bind to the transcriptional coregulator steroid receptor coactivator 1 with higher affinity when they are part of the heterodimer complex than when they are in their respective monomeric states. Furthermore, structural comparisons of the FXR/RXRalpha heterodimers and the FXR monomers bound with different ligands indicated that both heterodimerization and ligand binding induce conformational changes in the C terminus of helix 11 in FXR that affect the stability of the coactivator binding surface and the coactivator binding in FXR. In summary, our findings shed light on the allosteric signal transduction in the FXR/RXR heterodimer, which may be utilized for future drug development targeting FXR.

PMID- 30275018 TI - AKT and AMP-activated protein kinase regulate TBC1D1 through phosphorylation and its interaction with the cytosolic tail of insulin-regulated aminopeptidase IRAP. AB - In skeletal muscle, the Rab GTPase-activating (GAP) protein TBC1D1 is phosphorylated by AKT and AMP-activated protein kinase (AMPK) in response to insulin and muscle contraction. Genetic ablation of Tbc1d1 or mutation of distinct phosphorylation sites impairs intracellular GLUT4 retention and GLUT4 traffic, presumably through alterations of the activation state of downstream Rab GTPases. Previous studies have focused on characterizing the C-terminal GAP domain of TBC1D1 that lacks the known phosphorylation sites, as well as putative regulatory domains. As a result, it has been unclear how phosphorylation of TBC1D1 would regulate its activity. In the present study, we have expressed, purified, and characterized recombinant full-length TBC1D1 in Sf9 insect cells via the baculovirus system. Full-length TBC1D1 showed RabGAP activity toward GLUT4-associated Rab8a, Rab10, and Rab14, indicating similar substrate specificity as the truncated GAP domain. However, the catalytic activity of the full-length TBC1D1 was markedly higher than that of the GAP domain. Although in vitro phosphorylation of TBC1D1 by AKT or AMPK increased 14-3-3 binding, it did not alter the intrinsic RabGAP activity. However, we found that TBC1D1 interacts through its N-terminal PTB domains with the cytoplasmic domain of the insulin regulated aminopeptidase, a resident protein of GLUT4 storage vesicles, and this binding is disrupted by phosphorylation of TBC1D1 by AKT or AMPK. In summary, our findings suggest that other regions outside the GAP domain may contribute to the catalytic activity of TBC1D1. Moreover, our data indicate that recruitment of TBC1D1 to GLUT4-containing vesicles and not its GAP activity is regulated by insulin and contraction-mediated phosphorylation. PMID- 30275021 TI - DRESS syndrome due to vemurafenib treatment: switching BRAF inhibitor to solve a big problem. AB - We present a case report of an early-onset drug reaction with eosinophilia and systemic symptoms (DRESS syndrome) induced by vemurafenib (BRAF inhibitor) in a middle-age man affected by a metastatic, BRAF mutant melanoma who was started on first-line metastatic treatment with vemurafenib and cobimetinib.After initiating the treatment, the patient presented an extensive cutaneous rash with eosinophilia and renal impairment. Due the constellation of signs and symptoms, a diagnosis of DRESS syndrome was made which strongly contraindicated the reintroduction of vemurafenib due to its hypersensibility reaction. Thus, vemurafenib was stopped immediately, and we started corticoid treatment with clinical improvement.Due to the contraindication to start vemurafenib again, after multidisciplinary view of the case and having balanced the risks and benefits, we successfully performed a switch to another BRAF inhibitor in a progressively ascending pattern, without any skin toxicity and with a good response of the metastatic melanoma. PMID- 30275022 TI - Hypoxic hepatitis and furosemide. AB - Hypoxic hepatitis is a rather common complication of heart, circulatory or respiratory failure. We present the case of a patient with hypoxic hepatitis in the setting of heart failure and dehydration from furosemide as a reminder of an important clinical lesson. The pathogenesis of hypoxia (especially in the case of heart failure) is explained by a two-hit mechanism in which the liver at risk of hypoxic injury by passive hepatic congestion (right heart failure) is subsequently exposed to systemic hypoperfusion, which leads to a marked and transient elevation of aminotransferases. In the case presented, the use of furosemide (at least partially) promoted the second hit because it helped to generate hypotension and splanchnic hypovolaemia and favoured hepatic hypoxia. PMID- 30275023 TI - Use of long saphenous vein graft in acute on chronic mesenteric ischaemia. AB - Acute mesenteric ischaemia is a relatively rare surgical emergency, but despite advances in diagnostic tests, the mortality of this condition remains stubbornly high (50%-80%). This is principally because of the non-specific nature of the presenting symptoms and subsequent delay in diagnosis. We report an unusual case of acute mesenteric ischaemia treated by emergency laparotomy, small bowel resection and revascularisation using reversed long saphenous vein graft. PMID- 30275024 TI - A delayed diagnosis: recurrent fever and beta thalassaemia. AB - Familial Mediterranean fever and beta-thalassaemia are two genetic disorders, with a largely common geographical distribution. However, they have not much else in common, as the first is an autoinflammatory disorder, while the other is a haemoglobinopathy. We describe a patient with known beta-thalassaemia intermedia who presented with recurrent fevers and he was diagnosed with familial Mediterranean fever 2 years later. We discuss whether there is an association between the two disorders and the cognitive biases that lead to the delay in the diagnosis of familial Mediterranean fever. PMID- 30275019 TI - Reinstating plasticity and memory in a tauopathy mouse model with an acetyltransferase activator. AB - Chromatin acetylation, a critical regulator of synaptic plasticity and memory processes, is thought to be altered in neurodegenerative diseases. Here, we demonstrate that spatial memory and plasticity (LTD, dendritic spine formation) deficits can be restored in a mouse model of tauopathy following treatment with CSP-TTK21, a small-molecule activator of CBP/p300 histone acetyltransferases (HAT). At the transcriptional level, CSP-TTK21 re-established half of the hippocampal transcriptome in learning mice, likely through increased expression of neuronal activity genes and memory enhancers. At the epigenomic level, the hippocampus of tauopathic mice showed a significant decrease in H2B but not H3K27 acetylation levels, both marks co-localizing at TSS and CBP enhancers. Importantly, CSP-TTK21 treatment increased H2B acetylation levels at decreased peaks, CBP enhancers, and TSS, including genes associated with plasticity and neuronal functions, overall providing a 95% rescue of the H2B acetylome in tauopathic mice. This study is the first to provide in vivo proof-of-concept evidence that CBP/p300 HAT activation efficiently reverses epigenetic, transcriptional, synaptic plasticity, and behavioral deficits associated with Alzheimer's disease lesions in mice. PMID- 30275025 TI - Giant left breast hamartoma in a 45-year-old woman. AB - This is a case of a woman in her fifth decade of life who presented with a lump in her left breast. The patient underwent extensive breast investigations which did not confirm one particular diagnosis. The lesion was excised, and histological findings confirmed the diagnosis of a giant breast hamartoma. This case is interesting due to the largeness. As well as this, giant breast hamartomas are uncommon, and this case highlights the difficulty in their diagnosis and frequent misdiagnoses, potentially contributing to their reported low incidence rates. Diagnosis is difficult due to the complex appearance of the mass on imaging, raising the possibility of malignancy. Core biopsy is unremarkable, with the final diagnosis only possible on histological examination of the resected mass. PMID- 30275026 TI - Primary undifferentiated pleomorphic cardiac sarcoma with MDM2 amplification presenting as acute left-sided heart failure. AB - Primary cardiac tumours are a rare clinical entity that can present with myriad of non-specific cardiopulmonary symptoms. We describe a case of a 61-year-old previously healthy woman who presented with progressive dyspnoea and lower extremity swelling, suggestive of acute left-sided heart failure. Transthoracic echocardiogram revealed a large, 3.7*3.2 cm intracardiac mass resulting in severe mitral valvular dysfunction. The patient underwent surgical resection of the mass, however, negative margins were not obtained, and the tumour quickly returned. Histological and molecular analysis was consistent with the diagnosis of undifferentiated pleomorphic sarcoma with murine double minute 2 (MDM2) amplification. Given the overall grim prognosis, the patient chose to pursue comfort-based care. She died at home 9 months after the initial diagnosis. Here, we provide an updated review of the literature for the classification of undifferentiated pleomorphic cardiac sarcoma and potential treatment modalities. PMID- 30275027 TI - Primary amenorrhoea and clitoromegaly in a nulliparous woman: successful medical and surgical management. AB - Clitoromegaly is an important sign of virilisation and poses difficulty in sex determination, when present since birth. The diagnosis and treatment in an adult is a major challenge to the treating gynaecologist. The primary reason for its development is androgen excess due to congenital adrenal hyperplasia, polycystic ovarian syndrome, ovarian virilising tumours, neurofibromas, adrenal neoplasm and prolonged intake of anabolic steroids. A case of young nulliparous married woman who presented with primary amenorrhoea and clitoromegaly and was managed successfully has been reported.

AB - A 76-year-old woman with surgical history of Roux-en-Y gastric bypass presented with recurrent choledocholithiasis. Double balloon enteroscopy was unsuccessful in cannulating the biliary tree, thus, requiring surgically assisted endoscopic retrograde cholangiopancreaticogram (ERCP) access. Due to her stable clinical status, the non-urgent indication and multiple anticipated ERCPs for definitive biliary clearance, a more durable port of access to the ampulla was desired. A modified laparoscopic Janeway gastrostomy of the gastric remnant was performed and served as access for multiple subsequent endoscopic procedures with successful clearance of the biliary tree. PMID- 30275031 TI - Overall Approach to Trauma in the Emergency Department. PMID- 30275032 TI - Human and Animal Bites. AB - In the United States, nearly 56% of households owned a pet in 2011 according to the 2012 U.S. Pet Ownership & Demographics Sourcebook by the American Veterinary Medical Association. The survey also reports that approximately 70 million dogs and 74 million cats lived in households in the United States during the same year. (1)Human and animal bites are a frequent cause of primary care and emergency department visits for children. It is estimated that 250,000 human bites, 400,000 cat bites, and 4.5 million dog bites occur in the United States each year in both adults and children. (2) In the United States, approximately 10% of all human bites will become infected in a child with a bite wound. The infection rate of dog bites in children is 20%. Cat bite infection rates in children vary but can be up to 50%. Each type of bite wound has a predisposition for sex and/or age. Infected bite wounds manifest with swelling, erythema, and tenderness with or without drainage of the affected site and can lead to serious complications. Most animal bite wounds are polymicrobial in nature. Pasteurella species (spp.) is the most common organism isolated from both cat and dog bites. The microbiology of human bites consists of both aerobic and anaerobic bacteria.Basic medical management of bite wounds includes thorough cleansing and debridement. Irrigation, closure, and need to obtain culture depend on the type of bite wound, the appearance of the wound, the and timing of medical evaluation after the initial injury. Amoxicillin-clavulanate is the antibiotic of choice for prophylaxis and empirical therapy for children who are not allergic to penicillin. With most animal bites being preventable injuries, healthcare providers caring for children have an important role discussing pet safety with the child and the family.

AB - Bisphosphonates are widely used for treating osteoporosis, a common disorder in which bone strength is reduced, increasing the risk for fractures. Rarely, bisphosphonates can paradoxically lead to atypical fractures occurring spontaneously or with trivial trauma. Recently, a novel missense mutation (D188Y) in the GGPS1 gene, encoding for geranylgeranyl diphosphate synthase (GGPPS), was associated with bisphosphonate-induced atypical fractures. However, the molecular basis for GGPPS involvement in this devastating condition remains elusive. Here, we show that while maintaining an overall unperturbed global enzyme structure, the D188Y mutation leads to ~4-fold catalytic activity decrease. Furthermore, GGPPS-D188Y is unable to support cross-species complementation, highlighting the functional significance of the reduced catalytic activity observed in vitro. We next determined the crystal structure of apo-GGPPS-D188Y, revealing that while Y188 does not alter the protein fold, its bulky side chain sterically interferes with substrate binding. In agreement, we show that GGPPS-D188Y exhibits ~3-fold reduction in the binding affinity of zoledronate, a commonly used bisphosphonate. However, inhibition of the mutated enzyme by zoledronate, in pharmacologically relevant concentrations, is maintained. Finally, we determined the crystal structure of zoledronate-bound GGPPS-D188Y, revealing large ligand-induced binding pocket rearrangements, revising the previous model for GGPPS bisphosphonate interactions. In conclusion, we propose that among heterozygotes residual GGPPS activity is sufficient to support physiologic cellular function, concealing any pathologic phenotype. However, under bisphosphonate treatment, GGPPS activity is reduced below a crucial threshold for osteoclast function, leading to impaired bone remodeling and increased susceptibility to atypical fractures.

AB - GABAA receptors are the major inhibitory transmitter receptors in the brain. They are ligand-gated chloride channels and the site of action of benzodiazepines, barbiturates, neuroactive steroids, anesthetics, and convulsants. GABAA receptors are composed of five subunits that can belong to different subunit classes. The existence of 19 homologous subunits and their distinct regional, cellular, and subcellular distribution gives rise to a large number of GABAA receptor subtypes with distinct pharmacology, which modulate different functions of the brain. A variety of compounds have been identified that were claimed to modulate selectively individual GABAA receptor subtypes. However, many of these compounds have only incompletely been investigated or, in addition to a preferential modulation of a receptor subtype, also modulate other subtypes at similar concentrations. Although their differential efficacy at distinct receptor subtypes reduced side effects in behavioral experiments in rodents, the exact receptor subtypes mediating their behavioral effects cannot be unequivocally delineated. In addition, the discrepant in vivo effects of some of these compounds in rodents and man raised doubts on the applicability of the concept of receptor subtype selectivity as a guide for the development of clinically useful drugs. Here, we provide an up-to-date review on the currently available GABAA receptor subtype-selective ligands. We present data on their actual activity at GABAA receptor subtypes, discuss the translational aspect of subtype-selective drugs, and make proposals for the future development of ligands with better anxioselectivity in humans. Finally, we discuss possible ways to strengthen the conclusions of behavioral studies with the currently available drugs.

PMID- 30275046 TI - Cutting Edge: Local Proliferation of Uterine Tissue-Resident NK Cells during Decidualization in Mice. AB - NK cells accumulate in adult murine and human uteri during decidualization induced physiologically, pathologically, or experimentally. Adoptive transfer studies indicate that uterine NK (uNK) cells arise from circulating progenitors. However, virgin uteri contain few circulating NK1.1+CD49a- conventional NK cells, whereas NK1.1+CD49a+ tissue-resident NK (trNK) cells are abundant. In this study, we employed a novel, immune-competent NK cell-specific reporter mouse to track accumulation of uNK cells during unmanipulated pregnancies. We identified conventional NK and trNK cells accumulating in both decidua basalis and myometrium. Only trNK cells showed evidence of proliferation. In parabiosis studies using experimentally induced deciduomata, the accumulated uNK cells were proliferating trNK cells; migrating NK cells made no contribution. Together, these data suggest proliferating trNK cells are the source of uNK cells during endometrial decidualization. PMID- 30275044 TI - Pathways to balance mitochondrial translation and protein import. AB - Mitochondria contain their own genome that encodes for a small number of proteins, while the vast majority of mitochondrial proteins is produced on cytosolic ribosomes. The formation of respiratory chain complexes depends on the coordinated biogenesis of mitochondrially encoded and nuclear-encoded subunits. In this review, we describe pathways that adjust mitochondrial protein synthesis and import of nuclear-encoded subunits to the assembly of respiratory chain complexes. Furthermore, we outline how defects in protein import into mitochondria affect nuclear gene expression to maintain protein homeostasis under physiological and stress conditions. PMID- 30275047 TI - Lysyl-Transfer RNA Synthetase Induces the Maturation of Dendritic Cells through MAPK and NF-kappaB Pathways, Strongly Contributing to Enhanced Th1 Cell Responses. AB - In addition to essential roles in protein synthesis, lysyl-tRNA synthetase (KRS) is secreted to trigger a proinflammatory function that induces macrophage activation and TNF-alpha secretion. KRS has been associated with autoimmune diseases such as polymyositis and dermatomyositis. In this study, we investigated the immunomodulatory effects of KRS on bone marrow-derived dendritic cells (DCs) of C57BL/6 mice and subsequent polarization of Th cells and analyzed the underlying mechanisms. KRS-treated DCs increased the expression of cell surface molecules and proinflammatory cytokines associated with DC maturation and activation. Especially, KRS treatment significantly increased production of IL 12, a Th1-polarizing cytokine, in DCs. KRS triggered the nuclear translocation of the NF-kappaB p65 subunit along with the degradation of IkappaB proteins and the phosphorylation of MAPKs in DCs. Additionally, JNK, p38, and ERK inhibitors markedly recovered the degradation of IkappaB proteins, suggesting the involvement of MAPKs as the upstream regulators of NF-kappaB in the KRS-induced DC maturation and activation. Importantly, KRS-treated DCs strongly increased the differentiation of Th1 cells when cocultured with CD4+ T cells. The addition of anti-IL-12-neutralizing Ab abolished the secretion of IFN-gamma in the coculture, indicating that KRS induces Th1 cell response via DC-derived IL-12. Moreover, KRS enhanced the OVA-specific Th1 cell polarization in vivo following the adoptive transfer of OVA-pulsed DCs. Taken together, these results indicated that KRS effectively induced the maturation and activation of DCs through MAPKs/NF-kappaB signaling pathways and favored DC-mediated Th1 cell response. PMID- 30275048 TI - EF Hand Domain Family Member D2 Is Required for T Cell Cytotoxicity. AB - Programmed cell death 1 (PD-1) is a major coinhibitory receptor and a member of the immunological synapse (IS). To uncover proteins that regulate PD-1 recruitment to the IS, we searched for cytoskeleton-related proteins that also interact with PD-1 using affinity purification mass spectrometry. Among these proteins, EF hand domain family member D2 (EFHD2), a calcium binding adaptor protein, was functionally and mechanistically analyzed for its contribution to PD 1 signaling. EFHD2 was required for PD-1 to inhibit cytokine secretion, proliferation, and adhesion of human T cells. Interestingly, EFHD2 was also required for human T cell-mediated cytotoxicity and for mounting an antitumor immune response in a syngeneic murine tumor model. Mechanistically, EFHD2 contributed to IS stability, lytic vesicles trafficking, and granzyme B secretion. Altogether, EFHD2 is an important regulator of T cell cytotoxicity and further studies should evaluate its role in T cell-mediated inflammation.

AB - The presence of inflammatory immune cells in human tumors raises a fundamental question in oncology: How do cancer cells avoid the destruction by immune attack? In principle, tumor development can be controlled by cytotoxic innate and adaptive immune cells; however, as the tumor develops from neoplastic tissue to clinically detectable tumors, cancer cells evolve different mechanisms that mimic peripheral immune tolerance in order to avoid tumoricidal attack. Here, we provide an update of recent accomplishments, unifying concepts, and future challenges to study tumor-associated immune cells, with an emphasis on metastatic carcinomas. PMID- 30275052 TI - Sex Differences in Cancer Driver Genes and Biomarkers. AB - Cancer differs significantly between men and women; even after adjusting for known epidemiologic risk factors, the sexes differ in incidence, outcome, and response to therapy. These differences occur in many but not all tumor types, and their origins remain largely unknown. Here, we compare somatic mutation profiles between tumors arising in men and in women. We discovered large differences in mutation density and sex biases in the frequency of mutation of specific genes; these differences may be associated with sex biases in DNA mismatch repair genes or microsatellite instability. Sex-biased genes include well-known drivers of cancer such as beta-catenin and BAP1 Sex influenced biomarkers of patient outcome, where different genes were associated with tumor aggression in each sex. These data call for increased study and consideration of the molecular role of sex in cancer etiology, progression, treatment, and personalized therapy.Significance: This study provides a comprehensive catalog of sex differences in somatic alterations, including in cancer driver genes, which influence prognostic biomarkers that predict patient outcome after definitive local therapy.

AB - High mobility group box 1 (HMGB1) is a multifunctional nuclear protein that translocates to the cytoplasm and is subsequently released to the extracellular space during infection and injury. Once released, it acts as a damage-associated molecular pattern and regulates immune and inflammatory responses. Respiratory syncytial virus (RSV) is a major cause of acute lower respiratory tract infections in infants and elderly, for which no effective treatment or vaccine is currently available. This study investigated the effects of HMGB1 on cytokine secretion, as well as the involvement of NF-kappaB and TLR4 pathways in RSV induced HMGB1 release in human airway epithelial cells (AECs) and its proinflammatory effects on several human primary immune cells. Purified HMGB1 was incubated with AECs (A549 and small alveolar epithelial cells) and various immune cells and measured the release of proinflammatory mediators and the activation of NF-kappaB and P38 MAPK. HMGB1 treatment significantly increased the phosphorylation of NF-kappaB and P38 MAPK but did not induce the release of cytokines/chemokines from AECs. However, addition of HMGB1 to immune cells did significantly induce the release of cytokines/chemokines and activated the NF kappaB and P38 MAPK pathways. We found that activation of NF-kappaB accounted for RSV-induced HMGB1 secretion in AECs in a TLR4-dependent manner. These results indicated that HMGB1 secreted from AECs can facilitate the secretion of proinflammatory mediators from immune cells in a paracrine mechanism, thus promoting the inflammatory response that contributes to RSV pathogenesis. Therefore, blocking the proinflammatory function of HMGB1 may be an effective approach for developing novel therapeutics.

AB - Sucrose is the major transport sugar in plants, and plays a primary role as an energy source and signal in adaptive and stress responses. An ability to quantify sucrose over time and space would serve to progress our understanding of these important processes. Current technologies used for sucrose mapping are unable to quantitatively visualize its distribution within tissues. Here, we present an infrared-based, microspectroscopic method that allows for the quantitative visualization of sucrose at a microscopic level of resolution (~12 um). This method can successfully model the sugar concentration in individual vascular bundles and within a complex organ such as the stem, leaf, or seed. The sensitivity of the assay ranges from 20 to 1000 mM. We applied this method to the cereal crop barley (Hordeum vulgare) and the model plant Arabidopsis thaliana to highlight the potential of the procedure for resolving the spatial distribution of metabolites. We also discuss the relevance of the method for studies on carbon allocation and storage in the context of crop improvement. PMID- 30275053 TI - Gene Regulatory Network Analysis Identifies Sex-Linked Differences in Colon Cancer Drug Metabolism. AB - Understanding sex differences in colon cancer is essential to advance disease prevention, diagnosis, and treatment. Males have a higher risk of developing colon cancer and a lower survival rate than women. However, the molecular features that drive these sex differences are poorly understood. In this study, we use both transcript-based and gene regulatory network methods to analyze RNA seq data from The Cancer Genome Atlas for 445 patients with colon cancer. We compared gene expression between tumors in men and women and observed significant sex differences in sex chromosome genes only. We then inferred patient-specific gene regulatory networks and found significant regulatory differences between males and females, with drug and xenobiotics metabolism via cytochrome P450 pathways more strongly targeted in females. This finding was validated in a dataset of 1,193 patients from five independent studies. While targeting, the drug metabolism pathway did not change overall survival for males treated with adjuvant chemotherapy, females with greater targeting showed an increase in 10 year overall survival probability, 89% [95% confidence interval (CI), 78-100] survival compared with 61% (95% CI, 45-82) for women with lower targeting, respectively (P = 0.034). Our network analysis uncovers patterns of transcriptional regulation that differentiate male and female colon cancer and identifies differences in regulatory processes involving the drug metabolism pathway associated with survival in women who receive adjuvant chemotherapy. This approach can be used to investigate the molecular features that drive sex differences in other cancers and complex diseases.Significance: A network-based approach reveals that sex-specific patterns of gene targeting by transcriptional regulators are associated with survival outcome in colon cancer. This approach can be used to understand how sex influences progression and response to therapies in other cancers. Cancer Res; 78(19); 5538-47. (c)2018 AACR.

AB - Heart failure is a burdensome cardiovascular condition associated with high rates of morbidity and mortality. The 3-month period after hospitalization is a vulnerable phase in which patients are at high risk for mortality and rehospitalization. To reduce risk during this period, patients with heart failure and reduced ejection fraction should receive guideline-directed pharmacological therapies-the right drugs at the right doses-before hospital discharge. Optimal pharmacotherapies for these patients include agents that suppress the renin angiotensin-aldosterone system, suppress the sympathetic nervous system, enhance vasodilation, slow heart rate when needed, and reduce excess volume. Because optimal prescription and adherence are both necessary to ensure the best clinical outcomes, nurses need to participate in interventions that optimize prescription and drug use over time. Collaboration with pharmacists and advanced practice acute care nurses may help ensure that medication selection and dosing are consistent with national guidelines. Use of a predischarge order set and electronic medical records checklist can enhance collaborative care. PMID- 30275057 TI - Time-Course Transcriptome Analysis of Arabidopsis Siliques Discloses Genes Essential for Fruit Development and Maturation. AB - Fruits protect the developing seeds of angiosperms and actively contribute to seed dispersion. Furthermore, fruit and seed development are highly synchronized and require exchange of information between the mother plant and the developing generations. To explore the mechanisms controlling fruit formation and maturation, we performed a transcriptomic analysis on the valve tissue of the Arabidopsis (Arabidopsis thaliana) silique using RNA sequencing. In doing so, we have generated a data set of differentially regulated genes that will help to elucidate the molecular mechanisms that underpin the initial phase of fruit growth and, subsequently, trigger fruit maturation. The robustness of our data set has been tested by functional genomic studies. Using a reverse genetics approach, we selected 10 differentially expressed genes and explored the consequences of their disruption for both silique growth and senescence. We found that genes contained in our data set play essential roles in different stages of silique development and maturation, indicating that our transcriptome-based gene list is a powerful tool for the elucidation of the molecular mechanisms controlling fruit formation in Arabidopsis. PMID- 30275061 TI - The Intranasal Route as an Alternative Method of Medication Administration. AB - Intranasal drug administration is a less invasive method of drug delivery that is easily accessible for adult and pediatric patients. Medications administered by the intranasal route have efficacy comparable to intravenous administration and typically have superior efficacy to subcutaneous or intramuscular routes. The intranasal route is beneficial in emergent situations when the intravenous route is not available. The intranasal route is safe and effective in various indications, and therapeutic systemic concentrations of medication can be attained via this route. As the evidence for and comfort with intranasal administration continue to grow, guidance on correct technique, medications, and dosing is vital for appropriate use. This article reviews the process and practices of appropriate intranasal medication administration. PMID- 30275058 TI - Root Gravitropism Is Regulated by a Crosstalk between para-Aminobenzoic Acid, Ethylene, and Auxin. AB - Plants respond to gravitational force through directional growth along the gravity vector. Although auxin is the central component of the root graviresponse, it works in concert with other plant hormones. Here, we show that the folate precursor para-aminobenzoic acid (PABA) is a key modulator of the auxin-ethylene interplay during root gravitropism in Arabidopsis (Arabidopsis thaliana). In gravistimulated roots, PABA promotes an asymmetric auxin response, which causes the asymmetric growth responsible for root curvature. This activity requires the auxin response transcription factors AUXIN RESPONSE FACTOR7 (ARF7) and ARF19 as well as ethylene biosynthesis and signaling, indicating that PABA activity requires both auxin and ethylene pathways. Similar to ethylene, exogenous PABA reverses the agravitropic root growth of the auxin transport mutant pin-formed2 (pin2) and the auxin biosynthetic double mutant with loss of function of weak ethylene insensitive (wei) genes, wei8wei2, but not the pin2wei8wei2 triple mutant. This finding suggests that PABA regulates the ethylene-dependent reciprocal compensation between auxin transport and biosynthesis. Furthermore, manipulation of endogenous free PABA levels by modulating the expression of the gene encoding its glucosylation enzyme, UDP GLYCOSYL TRANSFERASE75B1, impacts the root graviresponse, suggesting that endogenous free PABA levels may play a crucial role in modulating the auxin ethylene cross talk necessary for root gravitropism.

AB - BACKGROUND: Unsuccessful extubation is associated with increased intensive care unit and hospital length of stays, hospital costs, morbidity, and mortality. The most common cause of reintubation is laryngeal edema, often evidenced by postextubation stridor. OBJECTIVE: To reduce the rates of postextubation stridor and reintubation in the neurocritical care unit at a large urban academic medical center. METHODS: A clinical pathway was created to aid in detecting patients expected to experience postextubation stridor and to guide prophylactic treatment. During the 12-week implementation phase, the pathway was completed on all intubated patients daily. RESULTS: The 12-week trial included a total of 606 days of mechanical ventilation. Checklists were completed for 531 days, a compliance rate of 88% for use of the clinical pathway. Of the 56 patients who were extubated during the trial, 54 had a checklist completed, for 96% compliance on the day of extubation. Outcomes after all nonpalliative extubations (n = 43) during the 12 weeks before and after implementation of the pathway (n = 56 periods) were evaluated by using chi 2 tests. Implementation of the pathway was associated with a significant reduction in rates of postextubation stridor (chi 2 = 6.2; P = .01), reintubation (chi 2 = 5.5; P = .02), and reintubation due to postextubation stridor (chi 2 = 8.3; P = .004). CONCLUSION: The clinical pathway implemented in the neurocritical care unit was safe and effective in reducing rates of reintubation and reintubation due to postextubation stridor.

AB - Pediatric cardiac failure is a significant problem that may be caused by cardiomyopathy, myocarditis, or congenital defects that cannot be surgically repaired. Long-term mechanical circulatory support (LTMCS) devices provide hemodynamic support for patients in heart failure as a bridge to heart transplant and, sometimes, cardiac recovery or destination therapy. Critical care nurses must have a comprehensive understanding of LTMCS device function and keen assessment skills to detect signs of impaired perfusion and device failure. Nurses should anticipate postoperative interventions, prevent adverse events, and be prepared to respond during emergencies. Patient care should be family centered and nurses must strive to maximize patients' quality of life throughout device implantation. This article provides a basic guide to caring for pediatric patients receiving LTMCS, including specific information regarding 4 devices that are often used for pediatric heart failure: Berlin Heart EXCOR, SynCardia Total Artificial Heart, HeartWare HVAD, and HeartMate II. PMID- 30275064 TI - Automated Audiovisual Feedback in Cardiopulmonary Resuscitation Training: Improving Skills in Pediatric Intensive Care Nurses. AB - BACKGROUND: High-quality cardiopulmonary resuscitation is associated with improved survival and neurological outcomes after cardiac arrest. Unfortunately, health care professionals frequently do not perform resuscitation within guidelines after life-support training. OBJECTIVES: To determine if brief intermittent training in cardiopulmonary resuscitation could improve nurses' skills to perform high-quality resuscitation 70% or more of the time during 2 minutes of cardiopulmonary resuscitation after 3 training sessions. METHODS: In a prospective single-center quality improvement program, pediatric critical care nurses had monthly training in cardiopulmonary resuscitation. A portable manikin/defibrillator with a chest compression sensor was used to provide corrective audiovisual feedback to optimize resuscitation skills. Resuscitation was practiced on an adult manikin. Target goals were compression depth 2 in or greater at a compression rate of 100/min to 120/minute. Percentage of time in the target range and mean compression depth and rate were recorded. Data were collected every other month. The percentage of time both compression rate and depth were in the target range was compared among nurses with different total numbers of training sessions. RESULTS: Of the 62 nurses who participated in the training, 48 had data collected. The median percentage of time in the target range improved from 29% with no training to 46% after 1 session, 54% after 2 sessions, 68% after 3 sessions, and 74% after 4 sessions (P = .001). Compression depth increased with the number of training sessions (P = .002). CONCLUSIONS: This training program in cardiopulmonary resuscitation yielded significant skill improvement and retention.

PMID- 30275069 TI - Hyperlactatemia and Patient Outcomes After Pediatric Cardiac Surgery. AB - Elevated serum lactate level, or hyperlactatemia, is often associated with alterations in tissue perfusion, increased risk for complications in the postoperative period, and patient mortality. Measuring lactate levels is a relatively simple and noninvasive method of obtaining useful data about an impending clinical deterioration in a seemingly hemodynamically stable patient. This article evaluates the current practice of measuring lactate levels in pediatric patients after cardiac surgery and the association between these levels and patient outcomes. The article addresses periods of increased risk for decreased perfusion, the critical postoperative period, use of lactate measurements in conjunction with a risk scoring system for pre-and postoperative congenital heart disease patients, and the implications of elevated lactate levels in nursing practice.

Specifically, the article reviews the importance of capacitance and compliance of the ventricles and their associated atrioventricular valves. For each of the defects discussed, the imaging modalities used to diagnose a marginal ventricle are reviewed and the surgical decision-making process is outlined. The article also reviews immediate postoperative treatment of these patients and when to consider biventricular repair of a marginal lesion to be a failure.

AB - Mouse embryos and fetal organs have no pigmentation except for the retinal pigmented epithelium of the eye at subsequent stages of development. This makes it difficult to visualize and photodocument embryonic structures using conventional light microscopy. A simple method is provided here that uses fluorescent nuclear stains. At the relatively low magnifications of dissecting microscopes, the nuclei of embryonic tissues essentially become "pixels" of fluorescence that "paint" the embryo, providing images similar to those obtained by low-magnification scanning electron microcopy (SEM). This method can be applied to standardly fixed whole embryos at least up to embryonic Day 14.5 (E14.5), and to embryos that have been processed for whole-embryo in situ hybridization and immunostaining. Dissected tissues and organs (e.g., palate, heart, lungs, gastrointestinal tract) may also be stained and visualized with this technique.

AB - Once primers and probes have been designed and obtained, it is necessary to optimize their concentration for each real-time polymerase chain reaction (PCR) assay. A set of PCRs is assembled in which the concentrations of forward and reverse primers are varied independently. Following amplification of the template DNA, amplification plots are compared. A standard curve is generated to determine the efficiency, sensitivity, and reproducibility of the assay. If SYBR Green I is used as the probe, then the melting curves are also analyzed. PMID- 30275075 TI - Constructing a Standard Curve for Real-Time Polymerase Chain Reaction (PCR) Experiments. AB - It is essential to prepare a standard curve for every real-time polymerase chain reaction (PCR) experiment. This protocol is used to construct a standard curve in which the template concentration is unknown. Such a standard curve is suitable for optimization experiments and for performing relative quantification by the standard curve method. To construct a standard curve for absolute quantification, the same principles apply as those presented here, but the concentration of the standards must be determined by an independent method. PMID- 30275076 TI - Quantification of DNA by Real-Time Polymerase Chain Reaction (PCR). AB - There are few differences between the experimental steps necessary for amplifying template DNA in a real-time thermocycler and a standard polymerase chain reaction (PCR). In real-time PCR, it is necessary, however, to optimize the concentration of primers and probe and to perform a standard curve. It is also important to consider the data analysis method that will be used. PMID- 30275077 TI - Quantification of RNA by Real-Time Reverse Transcription-Polymerase Chain Reaction (RT-PCR). AB - This protocol describes a real-time reverse transcription-polymerase chain reaction (RT-PCR) assay using a two-enzyme, two-tube approach, carried out using either SYBR Green I or TaqMan chemistries. The protocol uses a PCR volume of 20 uL (although most manufacturers recommend 50-uL reactions). However, if the PCR target is not very abundant (i.e., present at one to 10 copies per sample), a larger volume may yield better reproducibility between samples. Discussion on preparing high-quality RNA, choosing a priming method, selecting an enzyme, and selecting an endogenous reference gene is also included. PMID- 30275078 TI - Resolving Proteins for Immunoblotting by Gel Electrophoresis. AB - This protocol describes Tris/glycine SDS-polyacrylamide gel electrophoresis, also known as SDS discontinuous gel electrophoresis or the Laemmli electrophoresis system. The gel-casting unit is assembled and tested to make sure that there are no leaks. Ammonium persulfate and tetramethylethylenediamine are added to the separating monomer solution, and the bottom (separating) gel is poured and allowed to polymerize. The top (stacking) gel is poured, and the comb is inserted to make the wells. The stacking gel is allowed to polymerize and the comb is then removed. The gel cassette is connected to the buffer chambers and the samples are loaded into the wells. When the electric current is applied, the proteins migrate through the gel with a rate that is roughly proportional to the length of their polypeptide chains. The electrophoresis is stopped when the loading dye reaches the bottom of the separating gel. The gel cassette is disassembled, and the proteins are ready for transfer from the gel onto the membrane. PMID- 30275079 TI - Immunoblotting: Transfer of Proteins from Gels to Membranes. AB - Electrophoretic transfer of proteins from gels to membranes can be achieved either by complete immersion of a gel-membrane sandwich in a buffer (wet transfer) or by placing the gel-membrane sandwich between absorbent paper soaked in transfer buffer (semidry transfer). For the wet transfer, the sandwich is placed in a buffer tank with platinum wire electrodes. For the semidry transfer, the gel-membrane sandwich is placed between carbon plate or stainless steel electrodes. Both methods are described here and generally work well, although semidry transfer is quicker and often more complete. PMID- 30275080 TI - Making Weak Antigens Strong: Cross-Linking Peptides to KLH with Maleimide. AB - Haptens, which are small antigens such as peptides and drug compounds, are very weakly or nonimmunogenic by themselves and require the assistance of carrier proteins: complex molecules capable of eliciting a strong immune response in the host on injection. The haptens serve as epitopes for binding to the antibodies on the B-cell surface, and the carriers provide the MHC class II-T-cell receptor binding sites. Keyhole limpet hemocyanin (KLH) is one of the most widely used of such carrier proteins. KLH-hapten conjugates are commonly used in antibody generation in a variety of hosts such as mice, rats, and rabbits. Because KLH is harvested from mollusks, it is physiologically distant from mammalian species and less likely to produce antibodies that cross-react mammalian antigens. Maleimide activation of carrier proteins makes it possible to conjugate sulfhydryl containing haptens, and hence this chemistry is widely used for conjugating KLH with haptens. PMID- 30275081 TI - Analysis and Normalization of Real-Time Polymerase Chain Reaction (PCR) Experimental Data. AB - In real-time polymerase chain reaction (PCR), also called quantitative real-time PCR [or simply quantitative PCR (qPCR)] or kinetic PCR, the amplification of DNA is monitored by the detection and quantitation of a fluorescent reporter signal, which increases in direct proportion to the amount of PCR product in the reaction. The fluorescent reporter is excited by light from the real-time PCR machine, a fluorescence-detecting thermocycler. By recording the amount of fluorescence emission at each cycle, the PCR can be monitored during the exponential phase when the first significant increase in the amount of PCR product correlates with the initial amount of target template. The ability to quantify the amplified DNA during the exponential phase of the PCR, when none of the components of the reaction is limiting, has resulted in dramatically improved precision in the quantitation of target sequences. In addition, because of the high sensitivity of fluorometric detection, real-time PCR is capable of measuring the initial concentration of target DNA over a vast dynamic range (up to eight or nine orders of magnitude) and with a high degree of sensitivity (as little as one copy of template DNA). Although it is a powerful technique, researchers often face challenges in reliability and reproducibility because of the lack of assay standardization. Therefore, it is critical to optimize the reagents and reaction conditions, include proper internal and external controls, and perform rigorous data analysis in order to generate accurate and reproducible results in real-time PCR experiments. PMID- 30275082 TI - High Rate of Ceftobiprole Resistance among Clinical Methicillin-Resistant Staphylococcus aureus Isolates from a Hospital in Central Italy. AB - Ceftobiprole is a fifth-generation cephalosporin with activity against methicillin-resistant Staphylococcus aureus (MRSA). One-year surveillance at the Regional Hospital of Ancona (Italy) disclosed a 12% ceftobiprole resistance rate (12/102 isolates; MIC, >=4 mg/liter). Epidemiological characterization demonstrated that the resistant isolates all belonged to different clones. Penicillin-binding protein (PBP) analysis showed substitutions in all PBPs and a novel insertion in PBP2a. The mecB and mecC genes were not detected. Ceftobiprole susceptibility screening is essential to avoid therapeutic failure and the spread of ceftobiprole-resistant strains. PMID- 30275083 TI - Efficacious Analogs of the Lantibiotic Mutacin 1140 against a Systemic Methicillin-Resistant Staphylococcus aureus Infection. AB - Mutacin 1140, a member of the epidermin family of type AI lantibiotics, has a broad spectrum of activity against Gram-positive bacteria. It blocks cell wall synthesis by binding to lipid II. Although it has rapid bactericidal effects and potent activity against Gram-positive pathogens, its rapid clearance and short half-life in vivo limit its development in the clinic. In this study, we evaluated the effect of charged and dehydrated residues on the pharmacokinetics of mutacin 1140. The dehydrated residues were determined to contribute to the stability of mutacin 1140, while alanine substitutions for the lysine or arginine residues improved the pharmacological properties of the antibiotic. Analogs K2A and R13A had significantly lower clearances, leading to higher plasma concentrations over time. They also had improved bioactivities against several pathogenic bacteria. In a murine systemic methicillin-resistant Staphylococcus aureus (MRSA) infection model, a 10-mg/kg single intravenous bolus injection of the K2A and R13A analogs (1:1 ratio) protected 100% of the infected mice, while a 2.5-mg/kg dose resulted in 50% survival. The 10-mg/kg treatment group had a significant reduction in bacteria load in the livers and kidneys compared to that in the vehicle control group. The study provides lead compounds for the future development of antibiotics used to treat systemic Gram-positive infections. PMID- 30275084 TI - Selective Inhibition of Neisseria gonorrhoeae by a Dithiazoline in Mixed Infections with Lactobacillus gasseri. AB - The Gram-negative human pathogen Neisseria gonorrhoeae has progressively developed resistance to antibiotic monotherapies, and recent failures of dual drug therapy have heightened concerns that strains resistant to all available antibiotics will begin circulating globally. Targeting bacterial cell wall assembly has historically been effective at treating infections with N. gonorrhoeae, but as the effectiveness of beta-lactams (including cephalosporins) is challenged by increasing resistance, research has expanded into compounds that target the numerous other enzymes with roles in peptidoglycan metabolism. One example is the dithiazoline compound JNJ-853346 (DTZ), which inhibits the activity of an Escherichia coli serine protease l,d-carboxypeptidase (LdcA). Recently, the characterization of an LdcA homolog in N. gonorrhoeae revealed localization and activity differences from the characterized E. coli LdcA, prompting us to explore the effectiveness of DTZ against N. gonorrhoeae We found that DTZ is effective at inhibiting N. gonorrhoeae in all growth phases, unlike the specific stationary-phase inhibition seen in E. coli Surprisingly, DTZ does not inhibit gonococcal LdcA enzyme activity, and DTZ sensitivity is not significantly decreased in ldcA mutants. While effective against numerous N. gonorrhoeae strains, including recent multidrug-resistant isolates, DTZ is much less effective at inhibiting growth of the commensal species Lactobacillus gasseri DTZ treatment during coinfections of epithelial cells resulted in significant lowering of gonococcal burden and interleukin-8 secretion without significantly impacting recovery of viable L. gasseri This selective toxicity presents a possible pathway for the use of DTZ as an effective antigonococcal agent at concentrations that do not impact vaginal commensals.

AB - Neonatal sepsis and its accompanying inflammatory response contribute to substantial morbidity and mortality. Pentoxifylline (PTX), a phosphodiesterase inhibitor which suppresses transcription and production of proinflammatory cytokines, is a candidate adjunctive therapy for newborn sepsis. We hypothesized that PTX decreases live microbe-induced inflammatory cytokine production in newborn blood. Cord blood was stimulated with live microorganisms commonly encountered in newborn sepsis (Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, or Candida albicans) and simultaneously treated with antimicrobial agents (gentamicin, vancomycin, or amphotericin B) and/or clinically relevant concentrations of PTX. Microbial colony counts were enumerated by plating, supernatant cytokines were measured by multiplex assay, intracellular cytokines and signaling molecules were measured by flow cytometry, and mRNA levels were measured by quantitative reverse transcription-PCR. PTX inhibited concentration-dependent E. coli-, S. aureus-, S. epidermidis-, and C. albicans-induced tumor necrosis factor (TNF) and E. coli-induced interleukin 1beta (IL-1beta) production in whole blood, with greater suppression of proinflammatory cytokines in combination with antimicrobial agents. Likewise, PTX suppressed E. coli-induced monocytic TNF and IL-1beta, whereby combined PTX and gentamicin led to significantly greater reduction of TNF and IL-1beta. The anti inflammatory effect of PTX on microbe-induced proinflammatory cytokine production was accompanied by inhibition of TNF mRNA expression and was achieved without suppressing the production of the anti-inflammatory IL-10. Of note, microbial colony counts in newborn blood were not increased by PTX. Our findings demonstrated that PTX inhibited microbe-induced proinflammatory cytokine production, especially when combined with antimicrobial agents, without enhancing microbial proliferation in human cord blood in vitro, thus supporting its utility as candidate adjunctive agent for newborn sepsis. PMID- 30275088 TI - Trichlorination of a Teicoplanin-Type Glycopeptide Antibiotic by the Halogenase StaI Evades Resistance. AB - Glycopeptide antibiotics (GPAs) include clinically important drugs used for the treatment of infections caused by Gram-positive pathogens. These antibiotics are specialized metabolites produced by several genera of actinomycete bacteria. While many GPAs are highly chemically modified, A47934 is a relatively unadorned GPA lacking sugar or acyl modifications, common to other members of the class, but which is chlorinated at three distinct sites. The biosynthesis of A47934 is encoded by a 68-kb gene cluster in Streptomyces toyocaensis NRRL 15009. The cluster includes all necessary genes for the synthesis of A47934, including two predicted halogenase genes, staI and staK In this study, we report that only one of the halogenase genes, staI, is necessary and essential for A47934 biosynthesis. Chlorination of the A47934 scaffold is important for antibiotic activity, as assessed by binding affinity for the target N-acyl-d-Ala-d-Ala. Surprisingly, chlorination is also vital to avoid activation of enterococcal and Streptomyces VanB-type GPA resistance through induction of resistance genes. Phenotypic assays showed stronger induction of GPA resistance by the dechlorinated compared to the chlorinated GPA. Correspondingly, the relative expression of the enterococcal vanA resistance gene was shown to be increased by the dechlorinated compared to the chlorinated compound. These results provide insight into the biosynthesis of GPAs and the biological function of GPA chlorination for this medically important class of antibiotic. PMID- 30275089 TI - Emergence and Within-Host Genetic Evolution of Methicillin-Resistant Staphylococcus aureus Resistant to Linezolid in a Cystic Fibrosis Patient. AB - Methicillin-resistant Staphylococcus aureus (MRSA) infection has increased in recent years among cystic fibrosis (CF) patients. Linezolid (LZD) is one of the antistaphylococcal antibiotics widely used in this context. Although LZD resistance is rare, it has been described as often associated with long-term treatments. Thirteen MRSA strains isolated over 5 years from one CF patient were studied for LZD resistance emergence and subjected to whole-genome sequencing (WGS). Resistance emerged after three 15-day LZD therapeutic regimens over 4 months. It was associated with the mutation of G to T at position 2576 (G2576T) in all 5 rrl copies, along with a very high MIC (>256 mg/liter) and a strong increase in the generation time. Resistant strains isolated during the ensuing LZD therapeutic regimens and until 13 months after LZD stopped harbored only 3 or 4 mutated rrl copies, associated with lower MICs (8 to 32 mg/liter) and low to moderate generation time increases. Despite these differences, whole-genome sequencing allowed us to determine that all isolates, including the susceptible one isolated before LZD treatment, belonged to the same lineage. In conclusion, LZD resistance can emerge rapidly in CF patients and persist without linezolid selective pressure in colonizing MRSA strains belonging to the same lineage. PMID- 30275090 TI - Correlation of In Vitro Susceptibility Based on MICs and Squalene Epoxidase Mutations with Clinical Response to Terbinafine in Patients with Tinea Corporis/Cruris. AB - Recalcitrant dermatophytoses are on the rise in India. High MICs of terbinafine (TRB) and squalene epoxidase (SQLE) gene mutations conferring resistance in Trichophyton spp. have been recently documented. However, studies correlating laboratory data with clinical response to TRB in tinea corporis/cruris are lacking. For this study, we investigated the clinicomycological profile of 85 tinea corporis/cruris patients and performed antifungal susceptibility testing by CLSI microbroth dilution and SQLE mutation analysis of the isolates obtained and correlated these with the responses to TRB. Patients confirmed by potassium hydroxide (KOH) mounting of skin scrapings were started on TRB at 250 mg once a day (OD). If >50% clinical clearance was achieved by 3 weeks, the same dose was continued (group 1). If response was <50%, the dose was increased to 250 mg twice a day (BD) (group 2). If the response still remained below 50% after 3 weeks of BD, the patients were treated with itraconazole (ITR; group 3). Overall, skin scrapings from 64 (75.3%) patients yielded growth on culture. Strikingly, all isolates were confirmed to be Trichophyton interdigitale isolates by internal transcribed spacer (ITS) sequencing. Thirty-nine (61%) of the isolates had TRB MICs of >=1 ug/ml. Complete follow-up data were available for 30 culture-positive patients. A highly significant difference in modal MICs to TRB among the three treatment response groups was noted (P = 0.009). Interestingly, 8 of the 9 patients in group 3 harbored isolates exhibiting elevated TRB MICs (8 to 32 ug/ml) and SQLE mutations. The odds of achieving cure with TRB MIC < 1 ug/ml strains were 2.5 times the odds of achieving cure with the strain exhibiting MIC >=1 ug/ml.

AB - Isavuconazole may be useful in treating and preventing fungal infections in solid organ transplant (SOT) recipients due to its safety profile and activity against Aspergillus and some Mucorales Isavuconazole has favorable pharmacokinetics based on clinical trials in various patient populations, but data are limited in SOT recipients. We evaluated the steady-state pharmacokinetics of isavuconazole in 26 SOT recipients receiving the drug intravenously for prophylaxis. There was moderate interpatient variability in isavuconazole pharmacokinetic parameters (coefficients of variation of 51% for the area under the plasma concentration versus-time curve [AUC] and 59% for the trough plasma concentration [C trough]). AUC and steady-state C trough were significantly lower in women, patients with a body mass index of >=18.5 kg/m2, and those receiving hemodialysis. Trough plasma concentrations were highly correlated with AUCs (R 2 = 0.94) and can serve as a suitable measure of isavuconazole exposure in patients. In conclusion, moderate interpatient variability in isavuconazole exposure, the identification of factors associated with lower exposure, the recognition that C trough is a surrogate marker for AUC, and the availability of a simple analytical method suggest that therapeutic drug monitoring (TDM) may be useful for guiding treatment in at least some SOT recipients. Future studies are needed to correlate isavuconazole exposure with patients' clinical outcomes and to determine the clinical role of TDM.

AB - Plazomicin is an FDA-approved aminoglycoside for the treatment of complicated urinary tract infections. In this open-label study, 24 adults with normal renal function or mild, moderate, or severe renal impairment (n = 6 per group) received a single 7.5-mg/kg of body weight dose of plazomicin as a 30-min intravenous infusion. Total clearance declined with renal impairment, resulting in 1.98-fold and 4.42-fold higher plazomicin exposures, as measured by the area under the concentration-time curve from 0 h to infinity, in subjects with moderate and severe impairment, respectively, than in subjects with normal renal function.

PMID- 30275093 TI - Antimicrobial Susceptibility of 260 Clostridium botulinum Type A, B, Ba, and Bf Strains and a Neurotoxigenic Clostridium baratii Type F Strain Isolated from California Infant Botulism Patients. AB - Infant botulism is an infectious intestinal toxemia that results from colonization of the infant large bowel by Clostridium botulinum (or rarely, by neurotoxigenic Clostridium baratii or Clostridium butyricum), with subsequent intraintestinal production and absorption of botulinum neurotoxin that then produces flaccid paralysis. The disease is often initially misdiagnosed as suspected sepsis or meningitis, diagnoses that require prompt empirical antimicrobial therapy. Antibiotics may also be needed to treat infectious complications of infant botulism, such as pneumonia or urinary tract infection. Clinical evidence suggests (see case report below) that broad-spectrum antibiotics that are eliminated by biliary excretion may cause progression of the patient's paralysis by lysing C. botulinum vegetative cells in the large bowel lumen, thereby increasing the amount of botulinum neurotoxin available for absorption. The purpose of this antimicrobial susceptibility study was to identify an antimicrobial agent with little or no activity against C. botulinum that could be used to treat infant botulism patients initially diagnosed with suspected sepsis or meningitis, or who acquired secondary infections, without lysing C. botulinum Testing of 12 antimicrobial agents indicated that almost all California infant botulism patient isolates are susceptible to most clinically utilized antibiotics and are also susceptible to newer antibiotics not previously tested against large numbers of C. botulinum patient isolates. No antibiotic with little or no activity against C. botulinum was identified. These findings reinforce the importance of promptly treating infant botulism patients with human botulism immune globulin (BIG-IV [BabyBIG]).

AB - We assessed tenofovir exposure during pregnancy and postpartum in hepatitis B virus (HBV)-infected HIV-uninfected women receiving tenofovir disoproxil fumarate (TDF) to prevent mother-to-child transmission of HBV. Data from 154 women who received TDF within a randomized controlled trial were included. Individual plasma tenofovir exposures (area under the concentration-time curve from 0 to 24 h [AUC0-24]) were estimated using a population pharmacokinetic approach. The estimated geometric mean tenofovir AUC0-24 was 20% (95% confidence interval [95% CI], 19 to 21%) lower during pregnancy than during postpartum; this modest reduction in the absence of HBV transmission suggests that no dose adjustment is needed. PMID- 30275096 TI - Barriers to the release of human tissue for clinical trials research in the UK: a national survey of cellular pathology laboratories on behalf of the National Cancer Research Institute's Cellular Molecular Pathology (CM-Path) initiative. AB - AIM: To survey UK cellular pathology departments regarding their attitudes and practices relating to release of human tissue from their diagnostic archives for use in clinical trial research. METHODS: A 30-item questionnaire was circulated to the National Cancer Research Institute's Cellular Molecular Pathology initiative and Confederation of Cancer Biobanks mailing lists. Responses were collected over a 10-month period from November 2016 to August 2017. RESULTS: 38 departments responded to the survey, the majority of which regularly receive requests for tissue for research purposes. Most requests come from academia and financial support to facilitate tissue release comes from a variety of sources. A range of practices were reported in relation to selection of the most appropriate sample to release, consent checking, costing and governance frameworks. CONCLUSIONS: This survey demonstrates wide variation in practice across the UK and identifies barriers to release of human tissue for clinical trial research. Until we can overcome these obstacles, patient samples will remain inaccessible to research. Therefore, this study highlights the urgent need for clear and coordinated national guidance on this issue. PMID- 30275097 TI - CD138/syndecan-1 in pancreatic solid and pseudopapillary neoplasms. PMID- 30275095 TI - Dried Blood Spot Technique-Based Liquid Chromatography-Tandem Mass Spectrometry Method as a Simple Alternative for Benznidazole Pharmacokinetic Assessment. AB - Chagas disease (CD) is recognized as one of the major neglected global tropical diseases. Benznidazole (BNZ) is the drug of choice for the treatment of adults, young infants, and newborns with CD. However, the pharmacokinetics (PK) of BNZ have been poorly evaluated in all age groups, with consequent gaps in knowledge about PK-pharmacodynamic relationships in CD. The purpose of this study was to develop and validate a bioanalytical method to quantify BNZ levels in small volume whole-blood samples collected as dried blood spots (DBS). The analysis was performed using high-performance liquid chromatography-positive electrospray tandem mass spectrometry. PK evaluation in healthy male volunteers was conducted to verify the correlation between DBS and plasma BNZ concentrations. The calibration curve was linear from 50 to 20,000 ng . ml-1 Intra- and interday precision and bias values were less than 14.87% (n = 9) and 9.81% (n = 27), respectively. The recovery rates ranged from 94 to 100% with no matrix effect. There was no hematocrit level effect in a range of 20 to 70%. The PK results obtained from DBS and plasma were comparable (r 2 = 0.8295) and equivalent to previously published information on BNZ. BNZ in DBS was stable at room temperature for more than one year.

AB - Quantitative faecal immunochemical tests for haemoglobin (FIT) have now been advocated by the National Institute for Care and Health Excellence (NICE: DG30) to assist in the triage of patients presenting with symptoms that suggest a low risk of colorectal (bowel) cancer. The evidence is that FIT provides a good rule out test for significant bowel disease. However, a small number of cases will be missed, and robust safety-netting procedures are required to follow up some FIT negative patients. A range of diagnostic pathways are possible, and there is no best approach at present. Introduction of FIT requires careful consideration of the logistics of supply of devices and information to requesting sites and of transport to the laboratory. A number of FIT analytical systems are available. Three are documented as appropriate for use in assessment of patients with symptoms. However, preanalytical, analytical and postanalytical challenges remain. The methods have different specimen collection devices. The methods use polyclonal antibodies and there is no primary reference material or method to which FIT methods are standardised. Third-party internal quality control is lacking, and external quality assessment schemes have many difficulties in providing appropriate materials. Reporting of results should be done using ug Hb/g faeces units and with knowledge of the limit of detection and limit of quantitation of the analytical system used. FIT can be used successfully in an agreed diagnostic pathway, along with other clinical and laboratory information: this requires a multidisciplinary approach, providing opportunities for professionals in laboratory medicine involvement.

AB - Cutaneous melanoma causes most of the skin cancer deaths in the USA. Melanoma is the fifth most common cancer among men and the sixth most common cancer among women. The incidence of melanoma has risen sharply over the past three decades. In this review, which is informed by our extensive experience at a large cancer centre, we outline the key differences between the tumour, node and metastases staging criteria for cutaneous melanoma in the seventh and eighth editions of the AJCC Cancer Staging Manual We also offer advice on how to assess the histophenotypic parameters that are relevant for staging, with a special focus on avoiding potential pitfalls, and how to report all the prognostically and therapeutically relevant histophenotypic parameters. Correct assessment and reporting of these clinically relevant histophenotypic parameters is of outmost importance for practising pathologists because these parameters help treating clinicians select the most appropriate personalised treatment for patients in this era of promising targeted and immunotherapies. PMID- 30275099 TI - A real-world, comparative study of FDA-approved diagnostic assays PD-L1 IHC 28-8 and 22C3 in lung cancer and other malignancies. AB - AIMS: At the time of analysis, two widely used, drug-specific, tumour-cell programmed death ligand 1 (PD-L1) assays were approved by the US Food and Drug Administration for anti-PD-1 therapies: the Dako PD-L1 immunohistochemistry (IHC) 28-8 pharmDx assay and the Dako PD-L1 IHC 22C3 pharmDx assay. Given that the majority of current PD-L1 testing in US clinical practice is performed at commercial reference laboratories, we aimed to evaluate the concordance of the 28 8 and 22C3 assays in a real-world setting. METHODS: Matched PD-L1 IHC 28-8 and 22C3 results from routine assessment were obtained from 1930 patients, including 412 confirmed to have lung cancer, submitted from hospitals in over 38 US states/territories. Biopsies were stained, reviewed and scored by trained/certified pathologists at a single cancer reference laboratory between 2015 and 2017. Rate of concordance between assay findings was assessed by Bland Altman analysis; overall per cent agreement (OPA), positive per cent agreement and negative per cent agreement; and Cohen's kappa. RESULTS: PD-L1 IHC 28-8 and 22C3 displayed strong correlation across all samples and in samples with a confirmed lung cancer diagnosis irrespective of biopsy site. The OPA was 97%-98% for all samples, depending on the expression level defining PD-L1 positivity. In the Bland-Altman analysis, the mean difference in percentage of tumour cells positively stained for PD-L1 between the paired assay findings was -0.80% for all samples and -0.93% in samples with a confirmed lung cancer diagnosis. CONCLUSIONS: These data, in conjunction with recent findings, support the analytical concordance of the PD-L1 IHC 28-8 and 22C3 assays for assessing per cent tumour-cell membrane PD-L1 expression. PMID- 30275101 TI - Molecules in cancer immunotherapy: benefits and side effects. AB - This mini review describes some of the key interactions between cancer cells and the immune system. This includes the concept of tumour cell immunosurveillance, mechanisms of immune evasion by tumour cells and some of the novel immunology based anticancer therapies that have recently been introduced. The latter are also set into the context of the enlarging spectrum of immunohistochemistry-based and molecular testing that can now be performed on formalin-fixed and paraffin embedded tissues for predicting response to both well-established and newly developed agents. The emerging field of cancer immunotherapy requires and encourages close working between cellular and molecular pathology and clinical cancer treatment, while providing new hope for patients with cancers that may not have responded to conventional oncological treatments. PMID- 30275102 TI - Apoptotic colopathy: a pragmatic approach to diagnosis. AB - 'Apoptotic colopathy' is an umbrella term signifying a pattern of injury where the gastrointestinal biopsy shows a colitic picture with apoptosis as the predominant histological feature. Although the entities within apoptotic colopathy share a common histological feature- 'apoptosis', there is a list of varied clinical differential diagnoses that produce this similar histological pattern of injury. These include graft-versus-host disease, drug-induced injury due to multiple drugs (in particular, mycophenolate mofetil, check point inhibitor therapy and some others), infections (particularly cytomegalovirus, adenovirus and some others), immune disorders and other miscellaneous causes. However, the management of these varied differentials is strikingly different, thus necessitating an algorithmic approach for accurate diagnosis and optimal patient management. A definitive diagnosis requires interpretation of varied histological findings in the appropriate clinical context including clinical history, drug history and laboratory findings. This review will focus on the histopathological findings of varied entities that can manifest as 'apoptotic colopathy' on assessment of colonic biopsies.

PMID- 30275104 TI - Pathogenic and non-pathogenic Escherichia coli colonization and host inflammatory response in a defined microbiota mouse model. AB - Most Escherichia coli strains in the human intestine are harmless. However, enterohemorrhagic E coli (EHEC) is a foodborne pathogen that causes intestinal disease in humans. Conventionally reared (CONV) mice are inconsistent models for human infections with EHEC because they are often resistant to E coli colonization, in part due to their gastrointestinal (GI) microbiota. Although antibiotic manipulation of the mouse microbiota has been a common means to overcome colonization resistance, these models have limitations. Currently, there are no licensed treatments for clinical EHEC infections and, thus, new tools to study EHEC colonization need to be developed. Here, we used a defined microbiota mouse model, consisting of the altered Schaedler flora (ASF), to characterize intestinal colonization and compare host responses following colonization with EHEC strain 278F2 or non-pathogenic E coli strain MG1655. Significantly higher (P<0.05) levels of both strains were found in feces and cecal and colonic contents of C3H/HeN ASF compared to C3H/HeN CONV mice. GI inflammation was significantly elevated (P<0.05) in the cecum of EHEC 278F2-colonized compared to E. coli MG1655-colonized C3H/HeN ASF mice. In addition, EHEC 278F2 differentially modulated inflammatory-associated genes in colonic tissue of C3H/HeN ASF mice compared to E. coli MG1655-colonized mice. This approach allowed for prolonged colonization of the murine GI tract by pathogenic and non-pathogenic E coli strains, and for evaluation of host inflammatory processes. Overall, this system can be used as a powerful tool for future studies to assess therapeutics, microbe microbe interactions, and strategies for preventing EHEC infections. PMID- 30275105 TI - Structural insight into microtubule stabilization and kinesin inhibition by Tau family MAPs. AB - The Tau family microtubule-associated proteins (MAPs) promote microtubule stabilization and regulate microtubule-based motility. They share the C-terminal microtubule-binding domain, which includes three to five tubulin-binding repeats. Different numbers of repeats formed by alternative splicing have distinct effects on the activities of these proteins, and the distribution of these variants regulates fundamental physiological phenomena in cells. In this study, using cryo EM, we visualized the MAP4 microtubule complex with the molecular motor kinesin 1. MAP4 bound to the C-terminal domains of tubulins along the protofilaments stabilizes the longitudinal contacts of the microtubule. The strongest bond of MAP4 was found around the intertubulin-dimer interface such that MAP4 coexists on the microtubule with kinesin-1 bound to the intratubulin-dimer interface as well. MAP4, consisting of five repeats, further folds and accumulates above the intertubulin-dimer interface, interfering with kinesin-1 movement. Therefore, these cryo-EM studies reveal new insight into the structural basis of microtubule stabilization and inhibition of kinesin motility by the Tau family MAPs. PMID- 30275106 TI - Legionella remodels the plasma membrane-derived vacuole by utilizing exocyst components as tethers. AB - During the initial stage of infection, Legionella pneumophila secretes effectors that promote the fusion of endoplasmic reticulum (ER)-derived vesicles with the Legionella-containing vacuole (LCV). This fusion leads to a remodeling of the plasma membrane (PM)-derived LCV into a specialized ER-like compartment that supports bacterial replication. Although the effector DrrA has been shown to activate the small GTPase Rab1, it remains unclear how DrrA promotes the tethering of host vesicles with the LCV. Here, we show that Sec5, Sec15, and perhaps Sec6, which are subunits of the exocyst that functions in the tethering of exocytic vesicles with the PM, are required for DrrA-mediated, ER-derived vesicle recruitment to the PM-derived LCV. These exocyst components were found to interact specifically with a complex containing DrrA, and the loss of Sec5 or Sec15 significantly suppressed the recruitment of ER-derived vesicles to the LCV and inhibited intracellular replication of Legionella Importantly, Sec15 is recruited to the LCV, and Rab1 activation is necessary for this recruitment. PMID- 30275107 TI - Excitable RhoA dynamics drive pulsed contractions in the early C. elegans embryo. AB - Pulsed actomyosin contractility underlies diverse modes of tissue morphogenesis, but the underlying mechanisms remain poorly understood. Here, we combined quantitative imaging with genetic perturbations to identify a core mechanism for pulsed contractility in early Caenorhabditis elegans embryos. We show that pulsed accumulation of actomyosin is governed by local control of assembly and disassembly downstream of RhoA. Pulsed activation and inactivation of RhoA precede, respectively, the accumulation and disappearance of actomyosin and persist in the absence of Myosin II. We find that fast (likely indirect) autoactivation of RhoA drives pulse initiation, while delayed, F-actin-dependent accumulation of the RhoA GTPase-activating proteins RGA-3/4 provides negative feedback to terminate each pulse. A mathematical model, constrained by our data, suggests that this combination of feedbacks is tuned to generate locally excitable RhoA dynamics. We propose that excitable RhoA dynamics are a common driver for pulsed contractility that can be tuned or coupled differently to actomyosin dynamics to produce a diversity of morphogenetic outcomes. PMID- 30275109 TI - Bifunctional PD-1 * alphaCD3 * alphaCD33 fusion protein reverses adaptive immune escape in acute myeloid leukemia. AB - The CD33-targeting bispecific T-cell engager (BiTE) AMG 330 proved to be highly efficient in mediating cytolysis of acute myeloid leukemia (AML) cells in vitro and in mouse models. Yet, T-cell activation is correlated with upregulation of programmed cell death-ligand 1 (PD-L1) and other inhibitory checkpoints on AML cells that confer adaptive immune resistance. PD-1 and PD-L1 blocking agents may counteract T-cell dysfunction, however, at the expense of broadly distributed immune-related adverse events (irAEs). We developed a bifunctional checkpoint inhibitory T cell-engaging (CiTE) antibody that combines T-cell redirection to CD33 on AML cells with locally restricted immune checkpoint blockade. This is accomplished by fusing the extracellular domain of PD-1 (PD-1ex), which naturally holds a low affinity to PD-L1, to an alphaCD3.alphaCD33 BiTE-like scaffold. By a synergistic effect of checkpoint blockade and avidity-dependent binding, the PD 1ex attachment increases T-cell activation (3.3-fold elevation of interferon gamma) and leads to efficient and highly selective cytotoxicity against CD33+PD L1+ cell lines (50% effective concentration = 2.3-26.9 pM) as well as patient derived AML cells (n = 8). In a murine xenograft model, the CiTE induces complete AML eradication without initial signs of irAEs as measured by body weight loss. We conclude that our molecule preferentially targets AML cells, whereas high affinity blockers, such as clinically approved anticancer agents, also address PD L1+ non-AML cells. By combining the high efficacy of T-cell engagers with immune checkpoint blockade in a single molecule, we expect to minimize irAEs associated with the systemic application of immune checkpoint inhibitors and suggest high therapeutic potential, particularly for patients with relapsed/ refractory AML.

PMID- 30275108 TI - Bidirectional intraflagellar transport is restricted to two sets of microtubule doublets in the trypanosome flagellum. AB - Intraflagellar transport (IFT) is the rapid bidirectional movement of large protein complexes driven by kinesin and dynein motors along microtubule doublets of cilia and flagella. In this study, we used a combination of high-resolution electron and light microscopy to investigate how and where these IFT trains move within the flagellum of the protist Trypanosoma brucei Focused ion beam scanning electron microscopy (FIB-SEM) analysis of trypanosomes showed that trains are found almost exclusively along two sets of doublets (3-4 and 7-8) and distribute in two categories according to their length. High-resolution live imaging of cells expressing mNeonGreen::IFT81 or GFP::IFT52 revealed for the first time IFT trafficking on two parallel lines within the flagellum. Anterograde and retrograde IFT occurs on each of these lines. At the distal end, a large individual anterograde IFT train is converted in several smaller retrograde trains in the space of 3-4 s while remaining on the same side of the axoneme. PMID- 30275112 TI - The biobank consent debate: Why 'meta-consent' is not the solution? AB - Over the past couple of decades, there has been an ongoing, often fierce, debate about the ethics of biobank participation. One central element of that debate has concerned the nature of informed consent, must specific reconsent be gained for each new use, or user, or is broad consent ethically adequate? Recently, Thomas Ploug and Soren Holm have developed an alternative to both specific and broad consent: what they call a meta-consent framework. On a meta-consent framework, participants can choose the type of consent framework they require, for different kinds of use, different types of user and so on. Meta-consent involves a distinctive kind of design of the consent process. Here it is argued, first, that although a meta-consent framework does not wrong participants, Ploug and Holm understate the likely costs and burdens of such a framework, so there are good practical reasons not to offer it. Second, although Ploug and Holm allude to some ethical considerations that might seem to ground an ethical argument for providing meta-consent, they do not offer any sound argument, and it does not wrong participants in any way to fail to offer them the opportunity to design their own consent process. PMID- 30275110 TI - A synthesis approach of mouse studies to identify genes and proteins in arterial thrombosis and bleeding. AB - Antithrombotic therapies reduce cardiovascular diseases by preventing arterial thrombosis and thromboembolism, but at expense of increased bleeding risks. Arterial thrombosis studies using genetically modified mice have been invaluable for identification of new molecular targets. Because of low sample sizes and heterogeneity in approaches or methodologies, a formal meta-analysis to compare studies of mice with single gene defects encountered major limitations. To overcome these, we developed a novel synthesis approach to quantitatively scale 1514 published studies of arterial thrombus formation (in vivo and in vitro), thromboembolism and tail bleeding of genetically modified mice. Using a newly defined consistency parameter (CP), indicating the strength of published data, comparisons were made of 431 mouse genes, of which 17 consistently contributed to thrombus formation without affecting hemostasis. Ranking analysis indicated high correlations between collagen-dependent thrombosis models in vivo (FeCl3 injury or ligation/compression) and in vitro. Integration of scores and CP values resulted in a network of protein interactions in thrombosis and hemostasis (PITH), which was combined with databases of genetically linked human bleeding and thrombotic disorders. The network contained 2,946 nodes linked to modifying genes of thrombus formation, mostly with expression in megakaryocytes. Reactome pathway analysis and network characteristics revealed multiple novel genes with potential contribution to thrombosis/hemostasis. Studies with additional knockout mice revealed that 4/8 (Apoe, Fpr2, Ifnar1, Vps13a) new genes were modifying in thrombus formation. The PITH network further: (i) revealed a high similarity of murine and human hemostatic and thrombotic processes, and (ii) identified multiple new candidate proteins regulating these processes.

PMID- 30275115 TI - Dietary Heterocyclic Amine Intake and Colorectal Adenoma Risk: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Heterocyclic amines (HCAs) are potent carcinogenic substances formed in meat. Due to their mutagenic activity, they may increase the risk of colorectal adenomas (CRA), which are precursors of colorectal cancer (CRC), one of the most prevalent cancers worldwide. The aim of this meta-analysis was to synthesize the knowledge about the intake of HCAs and its associations with CRA. METHODS: We conducted a systematic search in PubMed and EMBASE. We used odds ratio (OR) (or relative risks, RR) from every reported intake and compared the highest versus lowest level of dietary HCAs. In addition, we assessed a dose response relationship. RESULTS: Twelve studies on HCA intake and risk of CRA were included in our analysis. We observed a significant association when comparing top versus bottom intake category of 2-amino-1-methyl-6-phenylimidazo[4,5 b]pyridine (PhIP) (OR= 1.20, 95% CI=1.12 to 1.29), 2-amino-3,8 dimethylimidazo[4,5-f]quinoxaline (MeIQx) (OR=1.20; 95% CI=1.08 to 1.34), 2- amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline (DiMeIQx) (OR=1.16; 95% CI=1.05 to 1.27), benzo(a)pyrene (BaP) (OR=1.15; 95% CI=1.04 to 1.27) and mutagenicity index (OR=1.22;95% CI=1.06 to 1.41). Furthermore, we observed a significant dose response effect for PhIP, MeIQx and mutagenicity index. CONCLUSION: This meta analysis suggests that there is a positive association of HCAs, BaP, mutagenicity index with risk of CRA. Additionally, our dose-response analyses showed an increased risk for CRA in the case of PhIP, MeIQx and mutagenicity index. IMPACT: This study provides evidence for a positive association between the dietary intake of meat mutagens and CRA risk. PMID- 30275114 TI - The influence of pre-diagnosis alcohol consumption and the polymorphisms of ethanol metabolizing genes on the survival of head and neck cancer patients. AB - BACKGROUND: Although alcohol drinking is an established risk factor of head and neck cancer (HNC), less is known about its role in the prognosis of HNC. The current study investigated the association between pre-treatment alcohol consumption and the overall survival (OS) of HNC patients. METHODS: Cox proportional hazards models were performed to evaluate the association between pre-diagnosis alcohol drinking and the OS of HNC patients. In addition, the influence of the polymorphisms of two ethanol metabolizing genes, ADH1B and ALDH2, on this relationship was also evaluated. RESULTS: The results showed a significant positive dose-response relationship between pre-diagnosis alcohol use and worse OS of HNC patients. This association was more significant for oropharyngeal cancer, hypopharyngeal cancer, and laryngeal cancer than for oral cancer. The association between alcohol use and the poorer OS of HNC patients was mainly through its association with a higher stage of HNC at diagnosis. The worst OS associated with alcohol use was observed among HNC patients with the fast ADH1B and the slow/non-functional ALDH2 genotype combination. CONCLUSIONS: Our analysis showed a significant positive dose-response relationship between pre diagnosis alcohol use and a worse OS of HNC. This association was mainly due to the higher stage of HNC among alcohol drinkers. In addition, the polymorphisms of the ethanol metabolizing gene, ADH1B and ALDH2, modified the relationship between pre-diagnosis alcohol use and the OS of HNC patients. IMPACT: Pre-diagnosis alcohol use may be a prognostic indicator of HNC. PMID- 30275116 TI - Multilevel regression for small-area estimation of mammography use in the United States, 2014. AB - BACKGROUND: The US Preventive Services Task Force recommends biennial screening mammography for average-risk women aged 50 to 74 years. County-level information on population measures of mammography use can inform targeted intervention to reduce geographic disparities in mammography use. County-level estimates for mammography use nationwide are rarely presented. METHODS: We used data from the 2014 Behavioral Risk Factor Surveillance System (BRFSS) (n=130,289 women), linked it to the American Community Survey poverty data, and fitted multilevel logistic regression models with two outcomes: mammography within the past 2 years (up-to date); and most recent mammography 5 or more years ago or never (rarely/never). We post-stratified the data with US Census population counts to run Monte Carlo simulations. We generated county-level estimates nationally and by urban-rural county classifications. County-level prevalence estimates were aggregated into state and national estimates. We validated internal consistency between our model based state-specific estimates and urban-rural estimates with BRFSS direct estimates using Spearman correlation coefficients and mean absolute differences. RESULTS: Correlation coefficients were 0.94 or larger. Mean absolute differences for the 2 outcomes ranged from 0.79 to 1.03. Although 78.45% (95% CI: 77.95% ?78.92%) of women nationally were up-to-date with mammography, more than half of the states had counties with >15% of women rarely/never using a mammogram, many in rural areas. CONCLUSIONS: We provided estimates for all U.S. counties and identified marked variations in mammography use. Many states and counties were far from the 2020 target (81.1%). IMPACT: Our results suggest a need for planning and resource allocation on a local level to increase mammography uptake.

AB - The intestines are key for the absorption of nutrients and water as well as drug metabolism, and it is well known that there are clear differences in the expression profile of drug metabolism enzymes along the intestinal tract. Yet only a few studies have thoroughly investigated regional differences in human intestinal drug metabolism. In this study, we evaluated phase I and phase II metabolism in matched human ileum and colon precision-cut intestinal slices (PCIS). To this end, human PCIS were incubated for 3 hours with testosterone and 7-hydroxycoumarin (7-HC) to examine phase I and phase II metabolism, respectively. Metabolite formation was assessed by high-performance liquid chromatography analysis. Our results demonstrated that androstenedione, 6beta hydroxytestosterone, 2beta-hydroxytestosterone, and 7-HC sulfate were predominantly formed in the ileum, while 15alpha-hydroxytestosterone and 7-HC glucuronide were mainly produced in the colon. Moreover, we also observed sex differences in phase II metabolite formation, which appeared to be higher in men compared with women. Taken together, we demonstrated that phase I metabolism predominantly occurs in ileum PCIS, while phase II metabolism mostly takes place in colon PCIS. Moreover, we revealed that human PCIS can be used to study both regional and sex differences in intestinal metabolism. PMID- 30275121 TI - What's happening in Innovations in Care Delivery.

AB - BACKGROUND: The impact of Aspergillus on lung disease in young children with cystic fibrosis is uncertain. AIMS: To determine if positive respiratory cultures of Aspergillus species are associated with: (1) increased structural lung injury at age 5 years; (2) accelerated lung function decline between ages 5 years and 14 years and (3) to identify explanatory variables. METHODS: A cross-sectional analysis of association between Aspergillus positive bronchoalveolar lavage (BAL) cultures and chest high-resolution CT (HRCT) scan findings at age 5 years in subjects from the Australasian Cystic Fibrosis Bronchoalveolar Lavage (ACFBAL) study was performed. A non-linear mixed-effects disease progression model was developed using FEV1% predicted measurements at age 5 years from the ACFBAL study and at ages 6-14 years for these subjects from the Australian Cystic Fibrosis Data Registry. RESULTS: Positive Aspergillus BAL cultures at age 5 years were significantly associated with increased HRCT scores for air trapping (OR 5.53, 95% CI 2.35 to 10.82). However, positive Aspergillus cultures were not associated with either FEV1% predicted at age 5 years or FEV1% predicted by age following adjustment for body mass index z-score and hospitalisation secondary to pulmonary exacerbations. Lung function demonstrated a non-linear decline in this population. CONCLUSION: In children with cystic fibrosis, positive Aspergillus BAL cultures at age 5 years were associated contemporaneously with air trapping but not bronchiectasis. However, no association was observed between positive Aspergillus BAL cultures on FEV1% predicted at age 5 years or with lung function decline between ages 5 years and 14 years.

PMID- 30275136 TI - An International Survey of Female Dental Students' Perceptions About Gender Bias and Sexual Misconduct at Four Dental Schools. AB - As women enter the dental profession in increasing numbers in North America and around the world, the questions of how they perceive their environment and what kind of barriers they face are important subjects to be addressed. The aim of this study was to assess and compare women dental students' perceptions of bias in their environment and experiences of sexual misconduct at one dental school in each of four countries. In spring 2017, 1,293 female students at four dental schools in the U.S., Bulgaria, Brazil, and India were invited to participate in a 24-item survey developed by researchers from the four countries; 990 students responded (response rate 76.6%). The overall majority of the respondents reported thinking the admissions process at their school was fair (79.7%); but a fifth of U.S. and Brazilian students perceived their school was not fully embracing of females, with most Bulgarian students agreeing (87.2%) and all Indian students disagreeing. Most respondents overall perceived that male faculty members did not favor male students (79.5%) and did not think there was discrimination against female students by faculty (87.1%), but half of the U.S. respondents reported feeling discriminated against by both male faculty and male students. When the responses "I've been verbally harassed" and "I've been somewhat verbally harassed" were combined, 10.1% of the U.S. respondents reported verbal harassment, compared to 20% of Brazilian, 15% of Bulgarian, and 2% of Indian respondents. When the responses "I've been sexually assaulted" and "I've been somewhat sexually assaulted" were combined, 6% of U.S. respondents reported being sexually assaulted, compared to 6.2% of Brazilian, 2.5% of Bulgarian, and none of the Indian respondents. Almost half (46.9%) of these students overall perceived their school was not or only somewhat vigilant about issues of sexual misconduct, and only 54% said they would feel comfortable or very comfortable reporting misconduct. These results suggest that academic dental institutions in all four countries need improvements to make their environments more equitable and free of bias and sexual misconduct. PMID- 30275137 TI - Oral Health and Dental Students' Perceptions of Their Clinical Learning Environment: A Focus Group Study. AB - Creating an optimal clinical learning environment poses a challenge to health professions educators. To evaluate and improve the clinical learning environment, it is necessary to understand students' experiences of their environment and the factors they perceive as having an impact on their learning. The aim of this explorative qualitative study was to examine University of Otago Faculty of Dentistry students' perceptions of their clinical learning environment to gain insights into how learning outcomes could be enhanced. In 2015, all approximately 600 students at all levels of the Bachelor of Oral Health and Bachelor of Dental Surgery degrees at the University of Otago, Dunedin, New Zealand, were invited to participate in focus groups. Focus groups facilitated by the faculty education research fellow and another researcher employed for the project were conducted during the second half of the academic year. Transcribed data were analyzed using a general inductive approach. Twenty-one students from all levels of the two programs attended one of six confidential focus groups. Three broad themes were evident in the results from all groups: feedback processes, assessments and grading, and tutor interactions. In the focus groups, students expressed dissatisfaction regarding current feedback practices, types of feedback to benefit learning, consistency in the grading system, and impact of different educators' teaching styles on learning. These results indicated a need for further research and curricular efforts to promote good student-teacher relationships in the clinical learning environment, which are paramount for creating an optimal teaching and learning environment and enhancing student outcomes. PMID- 30275138 TI - Comparison of Dental Students' Self-Evaluation and Faculty Evaluation of Communication Skills During a Standardized Patient Exercise. AB - The aims of this retrospective study, conducted in 2017, were to explore dental students' perceptions of their first standardized patient encounters and to assess the relationship between students' self-evaluation and faculty members' evaluation of students' communication skills in those encounters. Data from a simulation training laboratory at one U.S. dental school were obtained for all 46 second-year students, who had a standardized patient communication learning session. The students had completed self-evaluations before and after a debriefing with a clinical psychology and/or social work faculty member and three or four student peers. The faculty members had also completed evaluations of the students' communications skills. The results showed that the students found the standardized patient encounter helpful. The students rated "making an introduction" most positively. Students had a weighted Kappa agreement of 0.22 (p=0.024) with the faculty evaluations on their post-debriefing evaluation of overall communication skills, which was within the 0.21-0.40 range of fair agreement. This study found that, during their first standardized patient simulation exercise, the second-year students rated their overall communication skills in fair agreement with the faculty member after debriefing. PMID- 30275139 TI - Can Noncognitive Components of Admissions Data Predict Dental Student Performance and Postdoctoral Program Placement? AB - The aim of this retrospective cohort study was to evaluate whether the noncognitive factors of the dental student application, including undergraduate major and interview score, predicted success in the predoctoral program and placement in postdoctoral programs. The study population consisted of 169 students in the Harvard School of Dental Medicine DMD graduating Classes of 2012 through 2016. Noncognitive factors in the dental application, including letters of recommendation, extracurricular activities, undergraduate major, and dental school admission interview performance, were collected for the study population. Groups were analyzed for differences among undergraduate majors and any association between postgraduate placement and dental school performance. Dental school performance measures were grades obtained in the third and fourth years in a combination of preclinical and clinical course assessments. The results showed that neither interview score nor undergraduate major was significantly associated with dental school performance or postdoctoral program placement. There was a non significant association between interview score and performance in the course Treatment of Active Disease. These results suggest that noncognitive factors of the dental school application offered low yield to predicting predoctoral student performance and residency placements, with interview performance possibly outweighing undergraduate major in selection of successful predoctoral candidates. PMID- 30275140 TI - Preclinical Local Anesthesia Education in Dental Schools: A Systematic Review. AB - The aim of this systematic review was to evaluate the published literature on current educational techniques used to teach local anesthesia administration in U.S. dental schools to determine the methods by which potential complications may be minimized and efficacy maximized. A PubMed search was performed in June 2017 on the following terms: (local anesthesia, education, dental) AND (Humans[Mesh]). Out of 136 articles identified, 13 met the study criteria and were included for review. Of those, the nine with outcome measures were included in the qualitative synthesis. With a quality assessment tool designed for this study, the quality of each included article was assessed independently by three of the authors. Three main pedagogies were identified: didactic instruction based on textbooks and lectures, student-to-student injections, and use of anatomic models. However, the effects of these pedagogies on local anesthesia administration efficacy, patient satisfaction, and student confidence in administering local anesthesia were largely not assessed in these studies. Quality assessment of the reviewed articles yielded a mean score of 62% (range 44-83%) for the observational studies and a mean score of 56% (range 47-63%) for the interventional studies. Due to the heterogeneity of the studies assessed, no meta-analysis could be performed. While the experimental and observational studies reviewed provided some insight into the efficacy of current educational techniques, they had numerous methodological inconsistencies. The inconsistency of the available evidence made it difficult to make fully informed curriculum recommendations based on the existing literature. PMID- 30275141 TI - Mind the Gap: A Systematic Review of Implementation of Screening for Psychological Comorbidity in Dental and Dental Hygiene Education. AB - The biopsychosocial model is advocated as part of a more comprehensive approach in both medicine and dentistry. However, dentists have not traditionally been taught psychosocial screening as part of their predoctoral education. The aim of this systematic review was to provide an overview of published studies on the implementation of screening for psychological comorbidity in dental and dental hygiene education. The term "psychological comorbidity" refers to the degree of coexisting anxiety, depression, or other mental health problems in a patient presenting with a physical condition. The review followed a protocol registered in PROSPERO (CRD42016054083) and was carried out in accordance with the PRISMA guidelines. The methodological quality of the included studies was assessed using a ten-item tool developed for medical education. The electronic search in PubMed, Scopus, and PsycINFO from the inception of each database until December 31, 2016, together with a hand search, identified 1,777 articles. After abstracts were screened, 52 articles were reviewed in full text applying inclusion and exclusion criteria; four articles remained for the qualitative synthesis. Generally, the reported data on specific methods or instruments used for psychological screening were limited. Only one of the included articles utilized a validated screening tool. The results of this systematic review show that published data on the implementation of psychological patient assessment in dental and dental hygiene education are limited. To address this gap, the authors recommend short screening tools such as the Graded Chronic Pain Scale and the Patient Health Questionnaire for Depression and Anxiety. Educating dental and dental hygiene students about easy-to-use, reliable, and validated screening tools for assessing psychological comorbidity warrants more research attention and greater implementation in educational curricula. PMID- 30275142 TI - Dental Students' Performance in Detecting In Vitro Occlusal Carious Lesions Using ICDAS with E-Learning and Digital Learning Strategies. AB - The aim of this study was to assess the performance of dental students for detecting in vitro occlusal carious lesions using the International Caries Detection and Assessment System (ICDAS) with different learning strategies. A convenience sample of all 64 fourth-year dental students at a dental school in Brazil who had no previous experience with ICDAS was selected for the study in 2015. First, students performed the in vitro examination of the occlusal surfaces of 80 teeth according to ICDAS. Two weeks later, students were randomly allocated to three groups: G1 (n=21), ICDAS e-learning; G2 (n=22), ICDAS e-learning + digital learning tool (DLT); G3 (n=21), no training (control group). All students reexamined the 80 teeth according to ICDAS two weeks later. Sensitivity, specificity, and area under the ROC curve (AUC) were calculated according to three thresholds. Of the 64 students, 59 completed all study phases, for a 92.2% participation rate. The intra-group comparison found significantly higher sensitivity and specificity values for G1 and G2 students. G3 students showed an increased sensitivity at the D2 threshold. G2 was the only training strategy that resulted in significant improvement for the AUC. In the comparison of groups at the same threshold, G1 showed higher specificity at D3 threshold (0.78) than G2 (0.72) and G3 (0.73). Regarding sensitivity, G1 showed a lower value at D2 (0.91) threshold than G2 (0.94) and G3 (0.94). In this study, both training strategies (ICDAS e-learning and ICDAS e-learning + DLT) improved the performance of dental students for the in vitro detection of occlusal carious lesions, mainly when the association of methods was used. PMID- 30275143 TI - Evaluation of an Interprofessional Oral Health Assessment Activity in Advanced Practice Nursing Education. AB - The curriculum for nurse practitioner (NP) students often overlooks the assessment of the oral cavity. In recognition of this, the HEENT (head, eyes, ears, nose, and throat) assessment was expanded to HEENOT (head, ears, eyes, nose, oral, and throat) through integration of an interprofessional educational (IPE) activity developed for University of Colorado NP and dental students. The aim of this study was to assess NP students' perceptions of an IPE activity in which dental faculty and students taught NP students how to conduct an oral exam, recognize oral health pathology, and apply fluoride varnish. Afterwards, the NP students completed an evaluation survey focusing on their thoughts, comfort level, organization, and understanding of the activity. This IPE activity was repeated over four semesters from 2014 to 2017, and significant differences among the semesters were compared. All NP students in the four semesters participated in the activity and the survey: semester one N=25, semester two N=31, semester three N=43, and semester four N=25. In all semesters, NP students reported feeling more confident conducting oral health exams after completion of the IPE activity. Semester four students agreed more with the idea of interprofessional collaboration (OR: 0.103) and receiving educational information not learned elsewhere in the curriculum (OR: 0.134) compared to semester one students. Higher odds for the session being well organized and conducted in a suitable time were found for semester four compared to semester two (OR: 0.217). These comparisons reflect improvement in teaching methodologies over the four semesters and an overall increased confidence for NP students in performing an oral health assessment. PMID- 30275144 TI - Using Interprofessional Education to Promote Oral Health Literacy in a Faculty Student Collaborative Practice. AB - The aim of this study was to assess the oral health literacy knowledge gained by patients who are refugees, community members, and medical and nursing students after participating in an interprofessional education collaborative of students and faculty from the University of Texas Health San Antonio Schools of Dentistry, Medicine, and Nursing. In this faculty-student collaborative practice, all patients were triaged (including oral hygiene status and alcohol/tobacco use), and tailored treatment options were offered following assessment of their dental, medical, and social histories. The study was designed as a pre-post assessment of an educational intervention on oral health literacy. In the pretest, all groups were invited to respond to questionnaires assessing their knowledge of oral health. After participants engaged in oral hygiene instruction demonstrations and received information about an oral health literacy campaign, a posttest was conducted to assess knowledge gained. A total of 151 patients who were refugees, 38 medical students, 34 nursing students, and 17 community/parish members voluntarily participated in this initiative. Each group had a significant increase in mean oral health literacy score from pre- to posttest: patients 33.5%, community/parish members 22.3%, nursing students 20.8%, and medical students 13% (all p<0.0001). These results showed that the oral health literacy initiative helped increase all participants' oral health literacy and knowledge of preventive care. PMID- 30275145 TI - Design and Validation of a Basic Dental Psychomotor Skills Test for Novice Dental Students. AB - The aim of this study was to design and validate the Dental Psychomotor Skills (DePS) test as an instrument to assess dental students' psychomotor skills and to help educators adapt their academic practices to students' needs. The DePS test was created considering three of the main skills needed for dental study and practice. The dimensions measured in the test were Indirect Vision (IV) with 24 items, Instructions Follow-Up (FI) with 17 items, and Accuracy (A) with six items; each item was assessed at two stations. Scores were obtained with detailed rubrics, assessed by the same evaluator at each station. A total of 237 first year dental students, in four cohorts from 2012 to 2015, and 16 dental faculty instructors were evaluated. The construct validity of the instrument was supported by the rigorous build of ten stages, and the discriminative validity was supported by the comparison of the student and faculty results. The overall mean scores were 245.5+/-2.09 in the student group and 280.6+/-4.217 in the faculty group (difference: 35.15+/-7.00; p<0.001). Internal consistency was assessed by analyzing responses for each dimension using Cronbach's alpha, a statistical measure of reliability. Overall, Cronbach's alpha was 0.909 for dental students and 0.773 for faculty instructors. These results suggest that the DePS test is a valid test that could be used as a reliable basic skill tool at the beginning of the dental program to assess the abilities of novice dental students, to recognize student qualities, and to identify individuals requiring additional training.

PMID- 30275146 TI - Assessment of Psychometric Properties of an Oral Health Care Measure of Cultural Competence Among Dental Students Using Rasch Partial Credit Model. AB - Reliability, validity, and feasibility of the only validated oral health care measure of cultural competence, the Knowledge, Efficacy, and Practices Instrument (KEPI), have been confirmed. However, the instrument's psychometric properties including item and person reliability, category response functioning, and scale targeting, as well as differential scale functioning for subgroups, have not yet been examined. The aim of this study was to test the psychometric properties of KEPI among dental students using Rasch Partial Credit Model to determine if this model provided broader valid information that cannot be demonstrated according to Classical Test Theory. A total 1,290 dental students in the first or final semester at four U.S. dental schools were invited to participate in the study in 2016. Of those, 1,231 individuals completed the survey, for a 95.4% response rate. The participants were 613 males and 618 females and 889 non underrepresented minority (URM) and 342 URM students. The Rasch Partial Credit Model assessed the psychometric properties of KEPI's 20 items/three subscales. Differential scale functioning was found in the Culture-Centered Practice and Efficacy of Assessment subscales. Four items were endorsed differentially by gender; four items were endorsed differentially by URM/non-URM students. This study examined the psychometric properties of the KEPI using Rasch analysis to assess differential item functioning by dental student gender and race. The results provided valid evidence for the high internal reliability, measurement properties, and unidimensionality for the KEPI domains, ideal targeting, and well response category functioning, showing that the KEPI is a reliable instrument for measuring the subscales Knowledge of Diversity, Culture-Centered Practice skills, and Efficacy of Assessment for health care providers. PMID- 30275149 TI - Advancing Dental Education in the 21st Century: Phase 2 Report on Strategic Analysis and Recommendations. AB - In Phase 1 of the "Advancing Dental Education in the 21st Century" project, research was conducted and published on a number of serious challenges facing dental and allied dental education, both presently and projected to 2040. Those findings informed the strategic analysis and recommendations developed in Phase 2 of the project. This report provides an overview of the Phase 2 conclusions and presents recommendations to address the challenges identified. The recommendations propose ways to educate a workforce prepared to meet the oral health needs of the population; develop a sustainable economic model that allows schools to meet their education, research, and service missions; make dental and allied dental education and practice an integral part of the larger health education and delivery systems; and keep dentistry advancing as a "learned" profession. This report begins with an Executive Summary and then presents the strategic analysis of challenges facing dental schools and allied dental programs and provides a brief explanation of the rationale for each recommendation. Two appendices are included with the report: the first summarizes discussions held at the national conference to consider the recommendations; and the second provides additional documentation of calculations used to estimate the number of new dental graduates needed in 2040. PMID- 30275150 TI - The Endogenous Lusitropic and Chronotropic Agent, B-Type Natriuretic Peptide, Limits Cardiac Troponin Release in Cancer Patients with an Early Impairment of Myocardial Relaxation Induced by Anthracyclines. AB - We have reported that cancer patients treated with anthracycline-based or nonanthracycline chemotherapy developed an early impairment of myocardial relaxation at echocardiography or persistent elevations of the cardiac hormone B type natriuretic peptide (BNP). Post-hoc pharmacologic analyses showed that BNP elevations were induced by impaired relaxation and caused positive lusitropic effects that maintained normal relaxation. High BNP levels and impaired relaxation were therefore characterized as mutually exclusive manifestations of diastolic dysfunction, but high BNP levels resulted in positive chronotropism and inappropriate tachycardia. Some patients developed increased circulating levels of cardiac troponin I isoform (cTnI), a marker of cardiomyocyte necrosis. Here we have characterized whether cTnI elevations correlated with diastolic dysfunction that manifested as impaired relaxation or a high level of BNP. The effects of high BNP levels on cTnI elevations were also characterized. We show that impaired relaxation or high BNP levels were significantly more frequent in patients with cTnI elevations. High BNP levels diminished the plasma peak and area under the curve of cTnI, but this result was accompanied by inappropriate tachycardia. cTnI elevations occurred only in patients treated with anthracyclines; moreover, the association of impaired relaxation or high BNP levels with cTnI elevations was significantly more frequent in doxorubicin-treated patients compared with patients treated with its analog, epirubicin. These findings describe cause-and effect relations between impaired relaxation and cardiomyocyte necrosis, illuminate the role of anthracycline analogs, denote that the beneficial effects of BNP in relieving impaired relaxation and cardiomyocyte necrosis are counterbalanced by inappropriate tachycardia. Patients showing troponin elevations and impaired relaxation or high BNP levels should be treated with lusitropic drugs that lack a positive chronotropism. PMID- 30275152 TI - Targeting Canine KIT Promoter by Candidate DNA G-Quadruplex Ligands. AB - G-quadruplexes (G4) are nucleic acid secondary structures frequently assumed by G rich sequences located mostly at telomeres and proto-oncogenes promoters. Recently, we identified, in canine KIT (v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog) promoter, two G-rich sequences able to fold into G4: d_kit1 and d_kit2_A16. In this study, an anthraquinone (AQ1) and an anthracene derivative (AN6), known to stabilize the G4 structures of the corresponding human h_kit1 and h_kit2, were tested on the canine G4 and in two canine mast cell tumor (MCT) cell lines (C2 and NI-1) to verify their capability to down-regulate KIT expression. The cytotoxicity of AQ1 and AN6 was determined using the Alamar Blue test; also the constitutive expression of KIT and other proto-oncogenes containing G4 structures in their promoter (BCL2, VEGFalpha, VEGFR2, KRAS, and TERT) was assessed by quantitative real-time polymerase chain reaction (qRT-PCR). Then the time- and dose-dependent effects of both ligands on target gene expression were assessed by qRT-PCR. All target genes were constitutively expressed up to 96 hours of culture. Both ligands decreased KIT mRNA levels and c kit protein amount, and AN6 was comparatively fairly more effective. DNA interaction studies and a dual-luciferase gene reporter assay performed on a noncancerous canine cell line (Madin-Darby Canine Kidney cells) proved that this down-regulation was the result of the interaction of AN6 with KIT proximal promoter. Interestingly, our results only partially overlap with those previously obtained in human cell lines, where AQ1 was found as the most effective compound. These preliminary data might suggest AN6 as a promising candidate for the selective targeting of canine KIT-dependent tumors.

PMID- 30275151 TI - Brain-Permeant and -Impermeant Inhibitors of Fatty Acid Amide Hydrolase Synergize with the Opioid Analgesic Morphine to Suppress Chemotherapy-Induced Neuropathic Nociception Without Enhancing Effects of Morphine on Gastrointestinal Transit. AB - Opioid-based therapies remain a mainstay for chronic pain management, but unwanted side effects limit therapeutic use. We compared efficacies of brain permeant and -impermeant inhibitors of fatty acid amide hydrolase (FAAH) in suppressing neuropathic pain induced by the chemotherapeutic agent paclitaxel. Paclitaxel produced mechanical and cold allodynia without altering nestlet shredding or marble burying behaviors. We compared FAAH inhibitors that differ in their ability to penetrate the central nervous system for antiallodynic efficacy, pharmacological specificity, and synergism with the opioid analgesic morphine. (3'-(aminocarbonyl)[1,1'-biphenyl]- 3-yl)-cyclohexylcarbamate (URB597), a brain permeant FAAH inhibitor, attenuated paclitaxel-induced allodynia via cannabinoid receptor 1 (CB1) and cannabinoid receptor 2 (CB2) mechanisms. URB937, a brain impermeant FAAH inhibitor, suppressed paclitaxel-induced allodynia through a CB1 mechanism only. 5-[4-(4-cyano-1-butyn-1-yl)phenyl]-1-(2,4-dichlorophenyl)-N-(1,1 dioxido-4-thiomorpholinyl)-4-methyl-1H-pyrazole-3-carboxamide (AM6545), a peripherally restricted CB1 antagonist, fully reversed the antiallodynic efficacy of N-cyclohexyl-carbamic acid, 3'-(aminocarbonyl)-6-hydroxy[1,1'- biphenyl]-3-yl ester (URB937) but only partially reversed that of URB597. Thus, URB937 suppressed paclitaxel-induced allodynia through a mechanism that was dependent upon peripheral CB1 receptor activation only. Antiallodynic effects of both FAAH inhibitors were reversed by N-(piperidin-1-yl)-5-(4-iodophenyl)-1-(2,4 dichlorophenyl)-4-methyl-1H-pyrazole-3-carboxamide (AM251). Antiallodynic effects of URB597, but not URB937, were reversed by 6-iodo-2-methyl-1-[2-(4 morpholinyl)ethyl]-1H-indol-3-yl](4-methoxyphenyl)methanone (AM630). Isobolographic analysis revealed synergistic interactions between morphine and either URB597 or URB937 in reducing paclitaxel-induced allodynia. A leftward shift in the dose-response curve of morphine antinociception was observed when morphine was coadministered with either URB597 or URB937, consistent with morphine sparing. However, neither URB937 nor URB597 enhanced morphine-induced deficits in colonic transit. Thus, our findings suggest that FAAH inhibition may represent a therapeutic avenue to reduce the overall amount of opioid needed for treating neuropathic pain with potential to reduce unwanted side effects that accompany opioid administration. PMID- 30275155 TI - Biogeodynamics: bridging the gap between surface and deep Earth processes. AB - Life is sustained by a critical and not insubstantial set of elements, nearly all of which are contained within large rock reservoirs and cycled between Earth's surface and the mantle via subduction zone plate tectonics. Over geologic time scales, plate tectonics plays a critical role in recycling subducted bioactive elements lost to the mantle back to the ocean-biosphere system, via outgassing and volcanism. Biology additionally relies on tectonic processes to supply rock bound 'nutrients' to marine and terrestrial ecosystems via uplift and erosion. Thus, the development of modern-style plate tectonics and the generation of stable continents were key events in the evolution of the biosphere on Earth, and similar tectonic processes could be crucial for the development of habitability on exoplanets. Despite this vital 'biogeodynamic' connection, directly testing hypotheses about feedbacks between the deep Earth and the biosphere remains challenging. Here, I discuss potential avenues to bridge the biosphere-geosphere gap, focusing specifically on the global cycling and bioavailability of major nutrients (nitrogen and phosphorus) over geologic time scales.This article is part of a discussion meeting issue 'Earth dynamics and the development of plate tectonics'. PMID- 30275156 TI - Rates of generation and destruction of the continental crust: implications for continental growth. AB - Less than 25% of the volume of the juvenile continental crust preserved today is older than 3 Ga, there are no known rocks older than approximately 4 Ga, and yet a number of recent models of continental growth suggest that at least 60-80% of the present volume of the continental crust had been generated by 3 Ga. Such models require that large volumes of pre-3 Ga crust were destroyed and replaced by younger crust since the late Archaean. To address this issue, we evaluate the influence on the rock record of changing the rates of generation and destruction of the continental crust at different times in Earth's history. We adopted a box model approach in a numerical model constrained by the estimated volumes of continental crust at 3 Ga and the present day, and by the distribution of crust formation ages in the present-day crust. The data generated by the model suggest that new continental crust was generated continuously, but with a marked decrease in the net growth rate at approximately 3 Ga resulting in a temporary reduction in the volume of continental crust at that time. Destruction rates increased dramatically around 3 billion years ago, which may be linked to the widespread development of subduction zones. The volume of continental crust may have exceeded its present value by the mid/late Proterozoic. In this model, about 2.6 2.3 times of the present volume of continental crust has been generated since Earth's formation, and approximately 1.6-1.3 times of this volume has been destroyed and recycled back into the mantle.This article is part of a discussion meeting issue 'Earth dynamics and the development of plate tectonics'. PMID- 30275157 TI - Geological archive of the onset of plate tectonics. AB - Plate tectonics, involving a globally linked system of lateral motion of rigid surface plates, is a characteristic feature of our planet, but estimates of how long it has been the modus operandi of lithospheric formation and interactions range from the Hadean to the Neoproterozoic. In this paper, we review sedimentary, igneous and metamorphic proxies along with palaeomagnetic data to infer both the development of rigid lithospheric plates and their independent relative motion, and conclude that significant changes in Earth behaviour occurred in the mid- to late Archaean, between 3.2 Ga and 2.5 Ga. These data include: sedimentary rock associations inferred to have accumulated in passive continental margin settings, marking the onset of sea-floor spreading; the oldest foreland basin deposits associated with lithospheric convergence; a change from thin, new continental crust of mafic composition to thicker crust of intermediate composition, increased crustal reworking and the emplacement of potassic and peraluminous granites, indicating stabilization of the lithosphere; replacement of dome and keel structures in granite-greenstone terranes, which relate to vertical tectonics, by linear thrust imbricated belts; the commencement of temporally paired systems of intermediate and high dT/dP gradients, with the former interpreted to represent subduction to collisional settings and the latter representing possible hinterland back-arc settings or ocean plateau environments. Palaeomagnetic data from the Kaapvaal and Pilbara cratons for the interval 2780 2710 Ma and from the Superior, Kaapvaal and Kola-Karelia cratons for 2700-2440 Ma suggest significant relative movements. We consider these changes in the behaviour and character of the lithosphere to be consistent with a gestational transition from a non-plate tectonic mode, arguably with localized subduction, to the onset of sustained plate tectonics.This article is part of a discussion meeting issue 'Earth dynamics and the development of plate tectonics'. PMID- 30275158 TI - The evolution of plate tectonics. AB - To understand how plate tectonics became Earth's dominant mode of convection, we need to address three related problems. (i) What was Earth's tectonic regime before the present episode of plate tectonics began? (ii) Given the preceding tectonic regime, how did plate tectonics become established? (iii) When did the present episode of plate tectonics begin? The tripartite nature of the problem complicates solving it, but, when we have all three answers, the requisite consilience will provide greater confidence than if we only focus on the long standing question of when did plate tectonics begin? Earth probably experienced episodes of magma ocean, heat-pipe, and increasingly sluggish single lid magmatotectonism. In this effort we should consider all possible scenarios and lines of evidence. As we address these questions, we should acknowledge there were probably multiple episodes of plate tectonic and non-plate tectonic convective styles on Earth. Non-plate tectonic styles were probably dominated by 'single lid tectonics' and this evolved as Earth cooled and its lithosphere thickened. Evidence from the rock record indicates that the modern episode of plate tectonics began in Neoproterozoic time. A Neoproterozoic transition from single lid to plate tectonics also explains kimberlite ages, the Neoproterozoic climate crisis and the Neoproterozoic acceleration of evolution.This article is part of a discussion meeting issue 'Earth dynamics and the development of plate tectonics'. PMID- 30275159 TI - Crustal evolution and mantle dynamics through Earth history. AB - Resolving the modes of mantle convection through Earth history, i.e. when plate tectonics started and what kind of mantle dynamics reigned before, is essential to the understanding of the evolution of the whole Earth system, because plate tectonics influences almost all aspects of modern geological processes. This is a challenging problem because plate tectonics continuously rejuvenates Earth's surface on a time scale of about 100 Myr, destroying evidence for its past operation. It thus becomes essential to exploit indirect evidence preserved in the buoyant continental crust, part of which has survived over billions of years. This contribution starts with an in-depth review of existing models for continental growth. Growth models proposed so far can be categorized into three types: crust-based, mantle-based and other less direct inferences, and the first two types are particularly important as their difference reflects the extent of crustal recycling, which can be related to subduction. Then, a theoretical basis for a change in the mode of mantle convection in the Precambrian is reviewed, along with a critical appraisal of some popular notions for early Earth dynamics. By combining available geological and geochemical observations with geodynamical considerations, a tentative hypothesis is presented for the evolution of mantle dynamics and its relation to surface environment; the early onset of plate tectonics and gradual mantle hydration are responsible not only for the formation of continental crust but also for its preservation as well as its emergence above sea level. Our current understanding of various material properties and elementary processes is still too premature to build a testable, quantitative model for this hypothesis, but such modelling efforts could potentially transform the nature of the data-starved early Earth research by quantifying the extent of preservation bias.This article is part of a discussion meeting issue 'Earth dynamics and the development of plate tectonics'. PMID- 30275160 TI - The dependence of planetary tectonics on mantle thermal state: applications to early Earth evolution. AB - For plate tectonics to operate on a planet, mantle convective forces must be capable of forming weak, localized shear zones in the lithosphere that act as plate boundaries. Otherwise, a planet's mantle will convect in a stagnant lid regime, where subduction and plate motions are absent. Thus, when and how plate tectonics initiated on the Earth is intrinsically tied to the ability of mantle convection to form plate boundaries; however, the physics behind this process are still uncertain. Most mantle convection models have employed a simple pseudoplastic model of the lithosphere, where the lithosphere 'fails' and develops a mobile lid when stresses in the lithosphere reach the prescribed yield stress. With pseudoplasticity high mantle temperatures and high rates of internal heating, conditions relevant for the early Earth, impede plate boundary formation by decreasing lithospheric stresses, and hence favour a stagnant lid for the early Earth. However, when a model for shear zone formation based on grain size reduction is used, early Earth thermal conditions do not favour a stagnant lid. While lithosphere stress drops with increasing mantle temperature or heat production rate, the deformational work, which drives grain size reduction, increases. Thus, the ability of convection to form weak plate boundaries is not impeded by early Earth thermal conditions. However, mantle thermal state does change the style of subduction and lithosphere mobility; high mantle temperatures lead to a more sluggish, drip-like style of subduction. This 'sluggish lid' convection may be able to explain many of the key observations of early Earth crust formation processes preserved in the geologic record. Moreover, this work highlights the importance of understanding the microphysics of plate boundary formation for assessing early Earth tectonics, as different plate boundary formation mechanisms are influenced by mantle thermal state in fundamentally different ways.This article is part of a discussion meeting issue 'Earth dynamics and the development of plate tectonics'. PMID- 30275161 TI - Global tectonic evolution of Venus, from exogenic to endogenic over time, and implications for early Earth processes. AB - Venus provides a rich arena in which to stretch one's tectonic imagination with respect to non-plate tectonic processes of heat transfer on an Earth-like planet. Venus is similar to Earth in density, size, inferred composition and heat budget. However, Venus' lack of plate tectonics and terrestrial surficial processes results in the preservation of a unique surface geologic record of non-plate tectonomagmatic processes. In this paper, I explore three global tectonic domains that represent changes in global conditions and tectonic regimes through time, divided respectively into temporal eras. Impactors played a prominent role in the ancient era, characterized by thin global lithosphere. The Artemis superstructure era highlights sublithospheric flow processes related to a uniquely large super plume. The fracture zone complex era, marked by broad zones of tectonomagmatic activity, witnessed coupled spreading and underthrusting, since arrested. These three tectonic regimes provide possible analogue models for terrestrial Archaean craton formation, continent formation without plate tectonics, and mechanisms underlying the emergence of plate tectonics. A bolide impact model for craton formation addresses the apparent paradox of both undepleted mantle and growth of Archaean crust, and recycling of significant Archaean crust to the mantle.This article is part of a discussion meeting issue 'Earth dynamics and the development of plate tectonics'. PMID- 30275162 TI - The inception of plate tectonics: a record of failure. AB - The development of plate tectonics from a pre-plate tectonics regime requires both the initiation of subduction and the development of nascent subduction zones into long-lived contiguous features. Subduction itself has been shown to be sensitive to system parameters such as thermal state and the specific rheology. While generally it has been shown that cold-interior high-Rayleigh-number convection (such as on the Earth today) favours plates and subduction, due to the ability of the interior stresses to couple with the lid, a given system may or may not have plate tectonics depending on its initial conditions. This has led to the idea that there is a strong history dependence to tectonic evolution-and the details of tectonic transitions, including whether they even occur, may depend on the early history of a planet. However, intrinsic convective stresses are not the only dynamic drivers of early planetary evolution. Early planetary geological evolution is dominated by volcanic processes and impacting. These have rarely been considered in thermal evolution models. Recent models exploring the details of plate tectonic initiation have explored the effect of strong thermal plumes or large impacts on surface tectonism, and found that these 'primary drivers' can initiate subduction, and, in some cases, over-ride the initial state of the planet. The corollary of this, of course, is that, in the absence of such ongoing drivers, existing or incipient subduction systems under early Earth conditions might fail. The only detailed planetary record we have of this development comes from Earth, and is restricted by the limited geological record of its earliest history. Many recent estimates have suggested an origin of plate tectonics at approximately 3.0 Ga, inferring a monotonically increasing transition from pre plates, through subduction initiation, to continuous subduction and a modern plate tectonic regime around that time. However, both numerical modelling and the geological record itself suggest a strong nonlinearity in the dynamics of the transition, and it has been noted that the early history of Archaean greenstone belts and trondhjemite-tonalite-granodiorite record many instances of failed subduction. Here, we explore the history of subduction failure on the early Earth, and couple these with insights from numerical models of the geodynamic regime at the time.This article is part of a discussion meeting issue 'Earth dynamics and the development of plate tectonics'. PMID- 30275163 TI - The diversity of tectonic modes and thoughts about transitions between them. AB - Plate tectonics is a particular mode of tectonic activity that characterizes the present-day Earth. It is directly linked to not only tectonic deformation but also magmatic/volcanic activity and all aspects of the rock cycle. Other terrestrial planets in our Solar System do not operate in a plate tectonic mode but do have volcanic constructs and signs of tectonic deformation. This indicates the existence of tectonic modes different from plate tectonics. This article discusses the defining features of plate tectonics and reviews the range of tectonic modes that have been proposed for terrestrial planets to date. A categorization of tectonic modes relates to the issue of when plate tectonics initiated on Earth as it provides insights into possible pre-plate tectonic behaviour. The final focus of this contribution relates to transitions between tectonic modes. Different transition scenarios are discussed. One follows classic ideas of regime transitions in which boundaries between tectonic modes are determined by the physical and chemical properties of a planet. The other considers the potential that variations in temporal evolution can introduce contingencies that have a significant effect on tectonic transitions. The latter scenario allows for the existence of multiple stable tectonic modes under the same physical/chemical conditions. The different transition potentials imply different interpretations regarding the type of variable that the tectonic mode of a planet represents. Under the classic regime transition view, the tectonic mode of a planet is a state variable (akin to temperature). Under the multiple stable modes view, the tectonic mode of a planet is a process variable. That is, something that flows through the system (akin to heat). The different implications that follow are discussed as they relate to the questions of when did plate tectonics initiate on Earth and why does Earth have plate tectonics.This article is part of a discussion meeting issue 'Earth dynamics and the development of plate tectonics'. PMID- 30275164 TI - Laboratory investigation of mechanisms for phase mixing in olivine + ferropericlase aggregates. AB - To investigate the role of grain boundary pinning and the mechanisms by which phase mixing occurs during deformation of polymineralic rocks, we conducted high strain torsion experiments on samples consisting of olivine plus 30 vol% ferropericlase. Experiments were performed in a gas-medium deformation apparatus at 1524 K and 300 MPa. Samples were deformed to outer radius shear strains of up to gamma(R) = 14.1. The value of the stress exponent and the small grain sizes of our samples indicate that our two-phase material deformed by dislocation accommodated grain boundary sliding. In samples deformed to 1 < gamma < 7, elongated clusters of ferropericlase grains form thin layers in the olivine matrix, and small grains of ferropericlase appear at olivine grain boundaries and three- and four-grain junctions. By gamma ~ 14, a well-distributed mixture of small ferropericlase grains among the olivine grains developed. Microstructures exhibit similarities to both mechanical and chemical models proposed to describe the processes leading to phase mixing. Our results provide evidence for grain size reduction during phase mixing that results in a grain size significantly smaller than the value predicted by the single-phase recrystallization piezometer for olivine. Thus, phase mixing provides a mechanism for the persistent weakening of rocks that is important for developing and maintaining shear zones necessary for plate tectonics.This article is part of a discussion meeting issue 'Earth dynamics and the development of plate tectonics'. PMID- 30275165 TI - When crust comes of age: on the chemical evolution of Archaean, felsic continental crust by crustal drip tectonics. AB - The secular evolution of the Earth's crust is marked by a profound change in average crustal chemistry between 3.2 and 2.5 Ga. A key marker for this change is the transition from Archaean sodic granitoid intrusions of the tonalite trondhjemite-granodiorite (TTG) series to potassic (K) granitic suites, akin (but not identical) to I-type granites that today are associated with subduction zones. It remains poorly constrained as to how and why this change was initiated and if it holds clues about the geodynamic transition from a pre-plate tectonic mode, often referred to as stagnant lid, to mobile plate tectonics. Here, we combine a series of proposed mechanisms for Archaean crustal geodynamics in a single model to explain the observed change in granitoid chemistry. Numeric modelling indicates that upper mantle convection drives crustal flow and subsidence, leading to profound diversity in lithospheric thickness with thin versus thick proto-plates. When convecting asthenospheric mantle interacts with lower lithosphere, scattered crustal drips are created. Under increasing P-T conditions, partial melting of hydrated meta-basalt within these drips produces felsic melts that intrude the overlying crust to form TTG. Dome structures, in which these melts can be preserved, are a positive diapiric expression of these negative drips. Transitional TTG with elevated K mark a second evolutionary stage, and are blends of subsided and remelted older TTG forming K-rich melts and new TTG melts. Ascending TTG-derived melts from asymmetric drips interact with the asthenospheric mantle to form hot, high-Mg sanukitoid. These melts are small in volume, predominantly underplated, and their heat triggered melting of lower crustal successions to form higher-K granites. Importantly, this evolution operates as a disseminated process in space and time over hundreds of millions of years (greater than 200 Ma) in all cratons. This focused ageing of the crust implies that compiled geochemical data can only broadly reflect geodynamic changes on a global or even craton-wide scale. The observed change in crustal chemistry does mark the lead up to but not the initiation of modern-style subduction.This article is part of a discussion meeting issue 'Earth dynamics and the development of plate tectonics'. PMID- 30275166 TI - Magma oceans as a critical stage in the tectonic development of rocky planets. AB - Magma oceans are a common result of the high degree of heating that occurs during planet formation. It is thought that almost all of the large rocky bodies in the Solar System went through at least one magma ocean phase. In this paper, we review some of the ways in which magma ocean models for the Earth, Moon and Mars match present-day observations of mantle reservoirs, internal structure and primordial crusts, and then we present new calculations for the oxidation state of the mantle produced during the magma ocean phase. The crystallization of magma oceans probably leads to a massive mantle overturn that may set up a stably stratified mantle. This may lead to significant delays or total prevention of plate tectonics on some planets. We review recent models that may help alleviate the mantle stability issue and lead to earlier onset of plate tectonics.This article is part of a discussion meeting issue 'Earth dynamics and the development of plate tectonics'. PMID- 30275167 TI - Early earth geodynamics: cross examining the geological testimony. AB - Many studies link the presence of continents on Earth to the operation of plate tectonics. Radiogenic isotope data have, however, long consigned the bulk of crust generation and preservation to the murky realm of the Precambrian Earth, where the prevailing geodynamic systems are highly uncertain due to the sparse and complex nature of the geological record of these early eons. The purpose of this paper is to examine the nature of this geological record, considering the biases and artefacts that may undermine its fidelity, and to assess what are the most robust lines of evidence from which meaningful geodynamic inferences can be drawn. This is pursued with reference to Hadean detrital zircons, Archean gneiss complexes and Archean granite-greenstone terranes, and by considering isotopic proxies of crust-mantle interaction. The evidence reinforces long held views that the formation of some of the oldest continental nuclei involved a distinctive mode of planetary geodynamics that rests uneasily within definitions of modern style plate tectonics. A detailed interrogation of the oldest rocks, integrating multi-scale information from the best preserved whole-rock and mineral archives, and emphasizing careful selection at the sampling and analytical stages, will lead to the most robust input data for petrological and thermodynamic models of early Earth processes.This article is part of a discussion meeting issue 'Earth dynamics and the development of plate tectonics'.

AB - BACKGROUND: Tobacco use is prevalent among youth and adults in India. However, direct evidence on how increasing taxes or prices affect tobacco use onset is scarce. OBJECTIVE: To analyse the associations between cigarette and bidi prices and smoking onset in India, and how these associations differ by socioeconomic status. METHODOLOGY: The Wave 1 of the Tobacco Control Policy Evaluation India Survey by the International Tobacco Control Project contains information on the age at smoking onset for cigarettes and bidis. Using this information, data were expanded to a yearly pseudo-panel dataset that tracked respondents at risk of smoking onset from 1998 to 2011. The associations between bidi prices and bidi smoking onset, between cigarette prices and cigarette smoking onset, and between bidi and cigarette prices and any smoking onset were examined using a discrete time hazard model with a logit link function. Stratified analyses were conducted to examine the difference in these associations by rural versus urban division. RESULTS: We found that higher bidi prices were significantly associated with a lowered hazard of bidi smoking onset (OR 0.42, 95% CI 0.35 to 0.51). Higher cigarette prices were significantly (OR 0.87, 95% CI 0.83 to 0.92) associated with a lowered hazard of cigarette smoking onset among urban residents, but this association was non-significant when SEs were clustered at the state level. In addition, the association between increasing bidis prices and lowered hazards of bidi smoking onset was greater for urban residents than for rural ones (p<0.01). CONCLUSIONS: Under the new regime of a central goods and service system, policymakers may need to raise the prices of tobacco products sufficiently to curb smoking onset. PMID- 30275170 TI - Modelling the impact of a new tobacco product: review of Philip Morris International's Population Health Impact Model as applied to the IQOS heated tobacco product. AB - OBJECTIVES: We review the Population Health Impact Model (PHIM) developed by Philip Morris International and used in its application to the US Food and Drug Administration (FDA) to market its heated tobacco product (HTP), IQOS, as a modified-risk tobacco product (MRTP). We assess the model against FDA guidelines for MRTP applications and consider more general criteria for evaluating reduced risk tobacco products. METHODS: In assessing the PHIM against FDA guidelines, we consider two key components of the model: the assumptions implicit in the model (outcomes included, relative harm of the new product vs cigarettes, tobacco related diseases considered, whether dual or polyuse of the new product is modelled, and what other tobacco products are included) and data used to estimate and validate model parameters (transition rates between non-smoking, cigarette only smoking, dual use of cigarettes and MRTP, and MRTP-only use; and starting tobacco use prevalence). RESULTS: The PHIM is a dynamic state transition model which models the impact of cigarette and MRTP use on mortality from four tobacco attributable diseases. The PHIM excludes morbidity, underestimates mortality, excludes tobacco products other than cigarettes, does not include FDA-recommended impacts on non-users and underestimates the impact on other population groups. CONCLUSION: The PHIM underestimates the health impact of HTP products and cannot be used to justify an MRTP claim. An assessment of the impact of a potential MRTP on population health should include a comprehensive measure of health impacts, consideration of all groups impacted, and documented and justifiable assumptions regarding model parameters. PMID- 30275171 TI - The Role of Standing Variation in the Evolution of Weedines Traits in South Asian Weedy Rice (Oryza spp.). AB - Weedy rice (Oryza spp.) is a problematic weed of cultivated rice (O. sativa) around the world. Recent studies have established multiple independent evolutionary origins of weedy rice, raising questions about the traits and genes that are essential for the evolution of this weed. Among world regions, South Asia stands out due to the heterogeneity of its weedy rice populations, which can be traced to at least three origins: two through de-domestication from distinct cultivated rice varieties, and one from local wild rice (O. rufipogon/O. nivara). Here we examine five traits considered typical of or advantageous to weedy rice in weedy, cultivated and wild rice samples from South Asia. We establish that convergence among all three weed groups occurs for easy seed shattering, red pericarp color, and compact plant architecture, suggesting that these traits are essential for weed success in the South Asian agricultural environment. A high degree of convergence for black hull color is also seen among weeds with wild ancestors and weeds evolved from the aus cultivated rice group. We also examine polymorphism in five known domestication candidate genes, and find that Rc and Bh4 are associated with weed seed pericarp color and hull color, respectively, and weedy alleles segregate in the ancestral populations, as do alleles for the seed dormancy-linked gene Sdr4 The presence of a domestication related allele at the seed shattering locus, sh4, in weedy rice populations with cultivated ancestry supports a de-domestication origin for these weedy groups, and raises questions about the reacquisition of the shattering trait in these weedy populations. Our characterization of weedy rice phenotypes in South Asia and their associated candidate genes contribute to the emerging understanding of the mechanisms by which weedy rice evolves worldwide, suggesting that standing ancestral variation is often the source of weedy traits in independently evolved groups, and highlighting the reservoir of genetic variation that is present in cultivated varieties as well as in wild rice, and its potential for phenotypic evolution. PMID- 30275173 TI - Efficacy of a Covalent ERK1/2 Inhibitor, CC-90003, in KRAS Mutant Cancer Models Reveals Novel Mechanisms of Response and Resistance. AB - : As a critical signaling node, extracellular signal-regulated kinases (ERK1/2) are attractive drug targets, particularly in tumors driven by activation of the Mitogen Activated Protein Kinase (MAPK) pathway. Utility of targeting the MAPK pathway has been demonstrated by clinical responses to inhibitors of MEK1/2 or RAF kinases in some mutant-BRAF activated malignancies. Unlike tumors with mutations in BRAF, those with mutations in KRAS (>30% of all cancers and >90% of certain cancer types) are generally not responsive to inhibitors of MEK1/2 or RAF. Here, a covalent ERK1/2 inhibitor, CC-90003 was characterized and shown to be active in preclinical models of KRAS mutant tumors. A unique occupancy assay was used to understand the mechanism of resistance in a KRAS mutant patient derived xenograft model (PDX) of colorectal cancer (CRC). Finally, combination of CC-90003 with Docetaxel achieved full tumor regression and prevented tumor regrowth after cessation of treatment in a PDX model of lung cancer. This effect corresponded to changes in a stemness gene network, revealing a potential effect on tumor stem cell reprograming. IMPLICATIONS: Here, a covalent ERK1/2 inhibitor (CC-90003) is demonstrated to have preclinical efficacy in models of KRAS mutant tumors, which present a therapeutic challenge for currently available therapies.

AB - BACKGROUND/AIM: Endoscopic vacuum-assisted closure therapy (EVAC) is a promising new technique for repairing upper gastrointestinal defects of different etiologies. As of 2018, however, no standardized recommendation exists. This article reviewed EVAC in treating anastomotic leakage following major resective surgery of esophageal (EC) and gastric cancer (GC). MATERIALS AND METHODS: Only English-language literature was investigated. Only studies or data on EC and GC were included. Seven popular search engines (PubMed, Web of Science, ScienceDirect, Scopus, Google Scholar, ResearchGate, PubFacts) were utilized. RESULTS: A total of 29 studies (17 retrospective, six prospective and six case reports) with a total of 209 patients. Range of anastomotic leakage closure was 66.7-100%. Anastomotic stricture was the most frequent long-term related complication (18 cases). CONCLUSION: EVAC appears to be an extremely useful treatment for postsurgical anastomotic leakage in patients with EC/GC. Almost all kinds of anastomotic leakage (silent to symptomatic, small to large) seem to be amenable to this technique. PMID- 30275172 TI - Characterization of Genetic and Epigenetic Variation in Sperm and Red Blood Cells from Adult Hatchery and Natural-Origin Steelhead, Oncorhynchus mykiss. AB - While the goal of most conservation hatchery programs is to produce fish that are genetically and phenotypically indistinguishable from the wild stocks they aim to restore, there is considerable evidence that salmon and steelhead reared in hatcheries differ from wild fish in phenotypic traits related to fitness. Some evidence suggests that these phenotypic differences have a genetic basis (e.g., domestication selection) but another likely mechanism that remains largely unexplored is that differences between hatchery and wild populations arise as a result of environmentally-induced heritable epigenetic change. As a first step toward understanding the potential contribution of these two possible mechanisms, we describe genetic and epigenetic variation in hatchery and natural-origin adult steelhead, Oncorhynchus mykiss, from the Methow River, WA. Our main objectives were to determine if hatchery and natural-origin fish could be distinguished genetically and whether differences in epigenetic programming (DNA methylation) in somatic and germ cells could be detected between the two groups. Genetic analysis of 72 fish using 936 SNPs generated by Restriction Site Associated DNA Sequencing (RAD-Seq) did not reveal differentiation between hatchery and natural origin fish at a population level. We performed Reduced Representation Bisulfite Sequencing (RRBS) on a subset of 10 hatchery and 10 natural-origin fish and report the first genome-wide characterization of somatic (red blood cells (RBCs)) and germ line (sperm) derived DNA methylomes in a salmonid, from which we identified considerable tissue-specific methylation. We identified 85 differentially methylated regions (DMRs) in RBCs and 108 DMRs in sperm of steelhead reared for their first year in a hatchery environment compared to those reared in the wild. This work provides support that epigenetic mechanisms may serve as a link between hatchery rearing and adult phenotype in steelhead; furthermore, DMRs identified in germ cells (sperm) highlight the potential for these changes to be passed on to future generations. PMID- 30275174 TI - Immune Therapeutics in the Treatment of Advanced Gastric and Esophageal Cancer. AB - Systemic chemotherapy is the mainstay of therapy in patients with advanced gastric and esophageal cancer, but has multiple drawbacks including lack of durable efficacy and dose limited toxicities. Recent clinical trials data on the efficacy of immune therapy in this patient group have shed light on its potential as an alternative treatment option. Checkpoint inhibitors, specifically the anti PD-1/PD-L1 inhibitors, seem to be beneficial for a subgroup of patients with advanced gastric or esophageal cancer who have progressed on multiple systemic chemotherapies. As clinical trials results mature, it will become apparent whether checkpoint inhibitors are effective in other treatment settings such as in first-line therapy or adjuvant therapy. Although the toxicity of checkpoint inhibitors is generally unpredictable, they tend to be more manageable and better tolerated than the toxicities of systemic chemotherapy. Furthermore, recent research in molecular subtyping of esophageal and gastric cancer are paving way for better treatment response prediction and patient selection for checkpoint inhibitor therapies. Compared to checkpoint inhibitors, other types of immune therapies such as cancer vaccines, and adoptive cell therapies have yet to be proven effective in esophageal and gastric cancer and are further away from clinical use. Immune therapy seems poised to take a firm position as part of the therapeutic armamentarium for advanced gastric and esophageal cancer and future clinical trials will show the extent of its application in different treatment settings in this patient population. PMID- 30275176 TI - Spinal Ewing Sarcoma Debuting with Cord Compression: Have We Discovered the Thread of Ariadne? AB - Ewing's sarcoma (ES) of the spine with cord or radicular compression as an initial sign is infrequent. It is unclear, in alleviating a neurological deficit, whether decompressive laminectomy is preferred over chemotherapy. Herein, a literature review of the treatment approaches to the primary or metastatic ES of the spine has been performed. Collected data included clinical features of the patients, treatment, and outcome. There are reported 69 cases with initial presentation of cord or radicular compression of spinal cord, arising from primary or metastatic ES, treated either with initial chemotherapy and/or radiotherapy (RT) (33.33%, n=23), or decompressive surgery (66.66%, n=46). The median age at diagnosis was 17.95 years old (range=0.06-60), and 38 patients (55.07%) were male. Eighteen (78.26%) were initially treated with chemotherapy combined with RT, whereas 3 (13.04%) were managed with RT alone. One patient (4.35%) received only corticosteroids, while there are not available data for the treatment of another one (4.35%). The remaining 46 patients (66.66%) were initially treated with decompressive surgery. Among them, 40 (57.97%) received postoperative chemotherapy, RT or combined modality therapy, whereas 6 patients (8.69%) were not treated adjuvantly. Sixteen out of 23 patients (69.6%) treated with systemic therapy, and 37 from 46 (80.43%) of those managed with decompressive laminectomy were still alive at a mean follow-up period of 2.11 years (range=0.16-6) and 3.45 years (range=0.16-26.08), respectively. To summarize, spinal resection and reconstruction followed by adjuvant treatment reduce the risk of local recurrence, and improve long-term survival. However, ES of the spine is not a distinct clinical entity and can be either managed with chemotherapy and/or RT, similarly to other localization. PMID- 30275177 TI - Effect of Perioperative Lidocaine and Cisplatin on Metastasis in a Murine Model of Breast Cancer Surgery. AB - BACKGROUND/AIM: Mortality from breast cancer is usually attributable to metastasis. In vitro data suggest that amide local anaesthetics, e.g. lidocaine, inhibit metastasis by multiple mechanisms and recent in vivo data support this. Experimental data also suggest that opioids may inhibit cisplatin chemotherapy. Whether lidocaine would influence cisplatin chemotherapy has not been evaluated. MATERIALS AND METHODS: 4T1 cells were injected into the mammary gland of immunocompetent female BALB/c mice, with resection of the tumour under sevoflurane anaesthesia one week later. Mice (n=45) were randomized into one of three groups: The cisplatin group received 3 mg.kg-1 cisplatin; cisplatin and lidocaine group received 3 mg.kg-1 cisplatin and lidocaine bolus of 1.5 mg.kg-1 followed by an infusion of 2 mg.kg-1.h-1 The control group received sevoflurane only. All agents were given perioperatively. After 14 postoperative days, post mortem lung, serum and liver samples were collected. Primary outcome measure was lung metastasis colony count. RESULTS: During sevoflurane anaesthesia, the addition of lidocaine to cisplatin significantly decreased metastatic lung colony count [(mean+/-SD) (157+/-87)] compared to control [846+/-581, (p=0.001)], and cisplatin alone [580+/-383, (p=0.018)]. However, liver metastasis colony count was not reduced with the combination of cisplatin and lidocaine (9.3+/-13.9) when compared to control (74.7+/-257.3), p=0.78 or to cisplatin alone (110+/-388.8), p=0.569. Serum VEGF and interleukin-6 concentrations were not significantly different. CONCLUSION: In a 4T1 murine model of breast cancer surgery, under sevoflurane anaesthesia, lidocaine enhanced the metastasis-inhibiting action of cisplatin. Clinical evaluation of the hypothesis that co-administration of systemic lidocaine during cisplatin chemotherapy seems warranted. PMID- 30275178 TI - Thiasyrbactins Induce Cell Death via Proteasome Inhibition in Multiple Myeloma Cells. AB - BACKGROUND/AIM: Proteasome inhibition is a validated therapeutic strategy for the treatment of refractory and relapsed multiple myeloma (MM) and mantle cell lymphoma. We previously showed that thiasyrbactins (NAM compounds) are inhibitors with an affinity for the trypsin-like (T-L, beta2) site of the constitutive proteasome, and more profoundly for the T-L site of the immunoproteasome. MATERIALS AND METHODS: In this study, the biological activity of three NAM compounds was evaluated using four MM cell lines (ARD, U266, MM1R, and MM1S). We assessed the effect of (NAM-93, NAM-95, and NAM-105 on cell viability, as well as cell-based proteasomal activities, and determined the EC50 and Ki50 values, respectively. RESULTS: MM cells were most sensitive to NAM-93 with EC50 values <0.75 MUM after 48 h of treatment. NAM-105 had a similar profile in most of the MM cells with EC50 values ranging between 0.42 and 3.02 MUM. The level of inhibition of the proteasome T-L sub-catalytic activity in actively-growing MM cells was similar for NAM-93 and NAM-105. However, in each cell line, NAM-93 was more effective than NAM-105 at inhibiting overall trypsin-like sub-catalytic activity while NAM-105 was typically more effective at inhibiting overall chymotrypsin-like (CT-L, beta5) sub-catalytic activity. CONCLUSION: These results show for the first time the proteasome-targeted biological activity of thiasyrbactins in MM tumor cells. PMID- 30275179 TI - Panobinostat and Nelfinavir Inhibit Renal Cancer Growth by Inducing Endoplasmic Reticulum Stress. AB - BACKGROUND/AIM: There is no curative treatment for patients with advanced renal cancer. We believed that the combination of the histone deacetylase inhibitor panobinostat and the human immunodeficiency virus protease inhibitor nelfinavir would kill renal cancer cells by inducing endoplasmic reticulum (ER) stress. MATERIALS AND METHODS: Using renal cancer cells (769-P, 786-O, Caki-2), the ability of this combination to induce ER stress and its mechanism of action were investigated. RESULTS: The combination of drugs induced apoptosis and inhibited cancer growth effectively both in vitro and in vivo. Mechanistically, the combination induced ER stress and histone acetylation cooperatively. ER stress induction was shown to play a pivotal role in the anticancer effect of the combination because the protein synthesis inhibitor cycloheximide significantly attenuated combination-induced apoptosis. Nelfinavir was also found to increase the expression of the mammalian target of rapamycin (mTOR) inhibitor AMP activated protein kinase (AMPK) and inhibited the panobinostat-activated mTOR pathway. CONCLUSION: Panobinostat and nelfinavir inhibit renal cancer growth by inducing ER stress. PMID- 30275180 TI - Hotspot Mutations Detectable by Next-generation Sequencing in Exhaled Breath Condensates from Patients with Lung Cancer. AB - BACKGROUND: Genetic alterations occurring in lung cancer are the basis for defining molecular subtypes and essential for targeted therapies. Exhaled breath condensate (EBC) is a form of non-invasive sample that, amongst components, contains DNA from pulmonary tissue. Next-generation sequencing (NGS) was herein used to analyze mutations in EBC from patients with lung cancer. MATERIALS AND METHODS: EBC was collected from 26 patients with cancer and 20 healthy controls. Amplicon-based sequencing using Ion Ampliseq Colon and Lung Cancer gene panel v2 was applied. RESULTS: The sequencing was successful in 17 patients and 20 controls. EBC from patients revealed 39 hotspot mutations occurring in: adenomatous polyposis coli (APC), v-raf murine sarcoma viral oncogene homolog B (BRAF), discoidin domain receptor tyrosine kinase 2 (DDR2), epidermal growth factor receptor (EGFR), erb-b2 receptor tyrosine kinase 4 (ERBB4), F-box and WD repeat domain containing 7 (FBXW7), fibroblast growth factor receptor 1 (FGFR1), FGFR3 (fibroblast growth factor receptor 3), Kirsten rat sarcoma viral oncogene homolog (KRAS), mitogen-activated protein kinase kinase 1 (MAP2K1), met proto oncogene (MET), neuroblastoma RAS viral (v-ras) oncogene homolog (NRAS), phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA), phosphatase and tensin homolog (PTEN), ret proto-oncogene (RET), SMAD family member 4 (SMAD4), serine/threonine kinase 11 (STK11), and tumor protein p53 (TP53) genes. EBC from controls revealed 35 hotspot mutations. The average mutant allele fraction was higher in patients than controls. CONCLUSION: NGS can identify mutations in EBCs from patients with lung cancer. This could provide a promising non-invasive method for the assessment of gene mutations in lung cancer. PMID- 30275181 TI - Color-coded Imaging of the Circulating Tumor Cell Microenvironment. AB - BACKGROUND/AIM: Circulating tumor cells (CTCs) may initiate metastasis. Some studies show that the number of CTCs and existence of CTC clusters can be prognostic. In the present study, our color-coded imaging nude mouse model of metastatic lymphoma was utilized to investigate the microenvironment of CTC clusters using fluorescent-protein imaging. MATERIALS AND METHODS: EL-4 mouse lymphoma cells expressing red fluorescent protein (RFP) were injected into the spleen of transgenic C57B/6-green fluorescent protein (GFP) mice. Three weeks later, the number of CTCs and CTC clusters both in heart blood and portal blood were quantified and characterized using confocal microscopy for color-coded imaging. RESULTS: There was no significant difference in the number of CTCs between heart and portal blood. CTC clusters comprised 8.8% of CTCs, determined by color-coded imaging. Heterotypic CTC clusters containing other types of cells were distinguishable from homotypic CTCs. Heterotypic CTC clusters comprising cancer cells and fibroblasts were more rare than homotypic ones. Heterotypic CTC clusters with fibroblasts were observed only in portal blood, not in heart blood. CONCLUSION: CTCs can have variable properties depending on the blood source. CTCs can form clusters, which may contain fibroblast that may play a role in promoting CTC metastasis. Our results demonstrate the concept of the CTC microenvironment (CME), which may play a critical role in CTC behavior, including of metastasis. PMID- 30275183 TI - Theranostics with Hybrid Liposomes in an Orthotopic Graft Model Mice of Breast Cancer. AB - BACKGROUND/AIM: This study aimed to elucidate the therapeutic effects of hybrid liposomes (HL) composed of L-alpha-dimyristylphosphatidylcholine (DMPC) and polyoxyethylene [25] dodecyl ether (C12(EO)25) and the ability of HL-containing fluorescent probe to detect cancer in orthotopic graft model mice of breast cancer (MDA-MB-453). MATERIALS AND METHODS: HL composed of 90 mol% DMPC and 10 mol% C12(EO)25 were prepared by the sonication method. Anti-tumor activities of HL were investigated in vivo using orthotopic graft-bearing mice of MDA-MB-453 cells. RESULTS: With regard to the therapeutic effects of HL for breast cancer, HL inhibited the growth of MDA-MB-453 cells and induced apoptosis. Intravenous administration of HL resulted in a remarkable reduction of relative tumor weight in orthotopic graft model mice of breast cancer. The TUNEL assay revealed that this effect was due to induction of apoptosis. With regard to detection (diagnosis) of breast cancer, enhanced accumulation of HL carrying a fluorescence probe (Indocyanine green; ICG) was observed for MDA-MB-453 cells, although no accumulation of HL/ICG was obtained for normal breast cells. Enhanced accumulation of HL/ICG into the tumor of orthotopic graft model mice of breast cancer was observed. CONCLUSION: HL and HL/ICG could be theranostic targets since they showed therapeutic effects and ability to detect (diagnose) cancer in an orthotopic graft model mouse of breast cancer (MDA-MB-453). PMID- 30275182 TI - Oral Recombinant Methioninase Combined with Caffeine and Doxorubicin Induced Regression of a Doxorubicin-resistant Synovial Sarcoma in a PDOX Mouse Model. AB - BACKGROUND/AIM: Synovial sarcoma (SS) is a recalcitrant neoplasm with low chemosensitivity. We recently reported that recombinant methioninase (rMETase) inhibited SS growth in a patient-derived orthotopic xenograft (PDOX) mouse model and was more effective when administered in combination with the first-line drug doxorubicin (DOX). Caffeine enhances the efficacy of anticancer drugs by overcoming drug-induced cell-cycle arrest and increasing subsequent apoptosis. Here, we determined the efficacy of oral recombinant methioninase (o-rMETase) in combined with caffeine on an SS-PDOX model. MATERIALS AND METHODS: Mice bearing SS-PDOX tumors were randomized into four treatment groups of six: Untreated control; o-rMETase alone; o-rMETase with caffeine; DOX plus o-rMETase with caffeine. Tumor size and body weight were measured during the treatment and plasma L-methionine (MET) levels were measured at the end of treatment. RESULTS: All treatments significantly inhibited SS-PDOX tumor growth. Combining caffeine with o-rMETase was more effective than o-rMETase alone. DOX combined with o rMETase and caffeine led to regression of SS-PDOX. Plasma MET levels were reduced with o-rMETase treatment. CONCLUSION: These results suggest that combining o rMETase and caffeine along with first-line chemotherapy can be highly effective for SS and has clinical potential for this recalcitrant disease.

AB - BACKGROUND/AIM: Poor prognosis of pancreatic cancer has remained almost unchanged in recent years. Cold physical plasma was suggested as an innovative anticancer strategy, but its selective killing activity of malignant over non-malignant cells has only partially been explored. The present study aimed at exploring the effect of cold physical plasma on cellular viability. MATERIALS AND METHODS: Induction of cell death and apoptosis by cold physical plasma was investigated in murine PDA6606 pancreatic cancer cells and primary murine fibroblasts in vitro (2D and 3D cultures) and in ovo. RESULTS: Plasma increased apoptosis in PDA6606 to a significantly higher extent compared to fibroblasts. Antioxidants abrogated these effects, suggesting a prime role of reactive oxygen species in plasma induced apoptosis. Plasma increased apoptosis of 3D PDA6606 multicellular spheres grown in vitro and in ovo, to significantly higher rates compared to that of fibroblasts, with minimum in ovo inflammation or necrosis observed by hematoxylin and eosin staining (H&E). CONCLUSION: These data support the future intra operative application of cold physical plasma for the treatment of microscopic residual tumor tissue after surgical resection. PMID- 30275185 TI - Absence of HER2 Expression of Circulating Tumor Cells in Patients with Non Metastatic Esophageal Cancer. AB - BACKGROUND/AIM: The clinical significance of circulating tumor cells (CTC) in non metastatic esophageal cancer (EC) remains controversial and the cellular and molecular characteristics of CTCs are poorly understood. Especially the frequency and oncological impact of HER2 expression in CTCs in patients with EC have not been evaluated until now. MATERIALS AND METHODS: In this single-center, prospective study, peripheral blood samples were obtained preoperatively from 45 patients who were diagnosed with resectable EC. CTC detection and HER2 expression were performed using the CellSearch System. Data were correlated with clinicopathological parameters and patient outcomes. RESULTS: The study included 13 patients with squamous cell carcinomas (SCC) and 32 patients with adenocarcinomas (AC). HER2 gene amplification in the primary tumor was detected in 9.1% of patients. One or more CTCs were detected in 15.6% (SCC 1/13; AC 6/32) of the patients. None of the detected CTCs showed HER2 expression. Patients with CTCs showed significantly shorter relapse-free (p<0.001) and overall survival (p=0.015) than CTC-negative patients. CONCLUSION: This is the first study analyzing HER2 expression and the clinical significance of CTCs in patients with non-metastatic EC using an automated immunomagnetic detection system. HER2 expression in CTCs is very rare in patients with non-metastatic EC and seems to have a low clinical and oncological impact.

AB - As part of our continuing investigation on flavonoid derivatives as potential anticancer substances, a series of methoxylated and hydroxylated flavones was synthesized, and their cytotoxic and anti-proliferative activity was evaluated in leukemic HL60 cells. Their structure-activity relationship was also investigated. The correlation between the methoxylation/hydroxylation pattern and antiproliferative activity revealed the importance of the 5,4'- and 3',4' dihydroxyl moieties in flavone nucleus. PMID- 30275186 TI - The Contribution of MMP-7 Promoter Polymorphisms to Taiwan Lung Cancer Susceptibility. AB - BACKGROUND/AIM: Matrix metalloproteinase-7 (MMP-7) plays an important role in metastasis behavior of cancer cells, and overexpression of MMP-7 has been associated with poor prognosis in non-small cell lung cancer. However, the contribution of various genotypes of MMP-7 has not yet been investigated in lung cancer in Taiwan. Therefore, this study aimed to investigate the association of MMP-7 genotypes with lung cancer risk among the Taiwanese. MATERIALS AND METHODS: In this hospital-based case-control study, genotypes and distributions at two promoter sites of MMP-7, A-181G and C-153T, were determined, and their association with lung cancer risk in Taiwan was evaluated among 358 lung cancer patients and 716 age- and gender-matched healthy control individuals. In addition, the interaction of MMP-7 genotypes and smoking status were also examined. RESULTS: The percentages of variant AG and GG at MMP-7 A-181G in the lung cancer group were similar to the control group (12.8% and 2.3% vs. 11.3% and 1.5%, respectively; ptrend=0.5294). The allelic frequency distribution analysis showed that the variant G allele at MMP-7 A-181G conferred non-significant elevated lung cancer risk compared to the wild-type A allele [odds ratio (OR)=1.18, 95% confidence interval (CI)=0.85-1.66, p=0.2289]. As for the genotypes of MMP-7 C-153T, all the studied Taiwanese population was of CC genotype. Furthermore, there was no obvious joint effect of MMP-7 A-181G genotype and smoking status on the lung cancer risk. No statistically significant correlation was observed between MMP-7 A-181G genotype distributions and gender. CONCLUSION: There was no evidence that the genotypes of MMP-7 A-181G may act as a biomarker in determining personal susceptibility to lung cancer in Taiwan. PMID- 30275188 TI - P-gp Inhibition by the Anti-psychotic Drug Pimozide Increases Apoptosis, as well as Expression of pRb and pH2AX in Highly Drug-resistant KBV20C Cells. AB - BACKGROUND/AIM: The present study was designed to identify drugs that could sensitize P-glycoprotein (P-gp)-overexpressing resistant KBV20C cancer cells to treatment with Halaven (HAL) or vincristine (VIC). MATERIALS AND METHODS: Using relatively low doses or IC50 concentrations of drugs to sensitize anti-mitotic drug-resistant KBV20C cells, pimozide (PIM) sensitized HAL-resistant KBV20C cancer cells, with higher P-gp inhibitory activity than another anti-psychotic drug, fluphenazine (FLU). RESULTS: The first-generation P-gp inhibitor verapamil required a dose that was similar to that of PIM for P-gp inhibition, suggesting that PIM has a similar specificity for binding P-gp to prevent efflux of anti mitotic drugs. Furthermore, co-treatment with PIM and another anti-mitotic drug, VIC, also increased sensitization of KBV20C cells, suggesting that PIM can be combined with other anti-mitotic drugs to sensitize resistant cancer cells. PIM caused a reduction in cell viability and an increase in the number of cells arresting at the G2 phase of the cell cycle. PIM induced both early and late apoptosis in KBV20C cells in response to HAL treatment. Furthermore, the DNA damage marker pH2AX, the cell-cycle protein pRb, and the pro-apoptotic protein C PARP levels increased after HAL-PIM co-treatment, indicative of a mechanism involving G2 phase arrest and an increase in the number of cells undergoing apoptosis. CONCLUSION: PIM may be a promising therapeutic agent for the treatment of cancers that are resistant to anti-mitotic drugs. PMID- 30275189 TI - miR-3148 Is a Novel Onco-microRNA that Potentiates Tumor Growth In Vivo. AB - BACKGROUND/AIM: Alterations of microRNA expression in three-dimensional spheroids were examined to identify novel microRNAs that might be associated with tumorigenesis. MATERIALS AND METHODS: Using microRNA microarray analysis, we screened for microRNAs that were dramatically up-regulated inside three dimensional spheroids in genetically-modified HCT116 human colon cancer cells expressing Copepoda Green Fluorescent Protein under hypoxia. RESULTS: miR-3148 was identified as a possible candidate onco-microRNA. A growth advantage of HCT116 cells stably expressing miR-3148 (HCT116-miR3148) was observed compared to parental cells in vivo, but not in vitro. Additionally, no change in growth under hypoxic or starvation conditions was seen in these cells cultured two dimensionally; however, HCT116-miR3148 cells maintained as three-dimensional spheroids were highly resistant to hypoxic conditions. HCT116-miR3148 cells were more sensitive to mitogen-activated protein kinase (MAPK) kinase inhibitors and extracellular signal-regulated kinase (ERK) inhibitors. CONCLUSION: MiR-3148 may be a novel onco-microRNA that protects cancer cells from serious stress conditions through the MAPK/ERK pathway, especially in vivo. PMID- 30275190 TI - IL-8-251T>A (rs4073) Polymorphism Is Associated with Prognosis in Gastric Cancer Patients. AB - BACKGROUND/AIM: Inflammation is a key process in gastric carcinogenesis. Cytokines are mediators of inflammation and are involved in metastasis and tumorigenicity. We previously assessed the role of cytokine gene polymorphisms in gastric cancer risk in Chile. In the present study, we aimed to analyze whether these polymorphisms are associated with overall survival (OS) in gastric cancer (GC) patients. PATIENTS AND METHODS: A total of 153 individuals with GC diagnosis were followed-up for at least 2 years. Hazard ratios (HR) were estimated from Cox regression models using SNPs as predictor variables. The following SNPs were genotyped for study using a TaqMan assay: rs16944 (IL1B -511C>T); rs4073 (IL8 251 T>A); rs2275913 (IL-17 -197G>A); rs1800872 (IL10 -592 C>A); rs1800896 (IL10 1082A>G); rs28372698 (IL32). RESULTS: Interleukin-8 rs4073 (IL-8 -251T>A) showed association with OS under the dominant model (TA + AA) only when adjusted by clinicopathological variables (HR=1.64, 95%CI=1.05-2.55, p=0.030, q-value=0.18), but not with the univariate model (HR=1.51, 95%CI=0.98-2.31, p=0.062, q value=0.37). No significant differences were observed after adjusting for population stratification (PC1 and PC2 from Principal Component Analysis using genotypes from Infinium Global Screening Array). After stratification by clinicopathological variables, the association with shorter overall survival was higher among patients with diffuse-type tumors (HR=2.24, 95%CI=1.16-4.45) and patients with tumor size >5 cm (HR=1.79, 95%CI=1.08-2.97). CONCLUSION: These results suggest a role of IL-8 rs4073 in cancer prognosis. Its use as a prognostic marker of GC survival warrants further investigation. PMID- 30275191 TI - Evaluation of Therapeutic Potential of Phenoxodiol, a Novel Isoflavone Analog, in Renal Cancer Cells. AB - BACKGROUND/AIM: In the present study, the antineoplastic activity and mechanism of action of phenoxodiol, a novel isoflavone analog, was investigated in renal cancer cells. MATERIALS AND METHODS: A panel of renal cancer cells (769-P, 786-O, Caki-2) was treated with phenoxodiol in vitro, and the efficacy of treatment was evaluated. RESULTS: MTS assay results showed that phenoxodiol decreased renal cancer viability in a dose-dependent manner. In addition, it inhibited colony formation significantly and perturbed the cell cycle. Treatment with phenoxodiol increased the number of annexin-V-positive cells as well as the expression of cleaved poly ADP ribose polymerase, demonstrating that phenoxodiol induced apoptosis in renal cancer cells. Phenoxodiol also inhibited Akt pathway via dephosphorylation of Akt. CONCLUSION: Phenoxodiol inhibited Akt pathway and induced apoptosis of renal cancer cells. The present study provides a theoretical basis for future development of a novel therapy effective against renal cancer. PMID- 30275192 TI - Differential Effects of In Vitro Treatment with Cinobufotalin on Three Types of Ovarian Cancer Cells. AB - BACKGROUND/AIM: Cinobufotalin (CINO), a cardiotonic steroid, has been used as an anticancer agent. This study assessed the cell-specific effect of CINO on SK-OV 3, CRL-1978 and CRL-11731 ovarian cancer cells which differ in terms of their respective karyotypes. MATERIALS AND METHODS: Cell cultures were treated with CINO (0.1, 1, 5 and 10 MUM) for 24, 48, and 72 h. Cell proliferation, migration, and invasion were measured using CellTiter, Cytoselect, and FluoroBlock assays, respectively. Expression of proliferating cell nuclear antigen (PCNA) was evaluated by western blot analysis. Cell viability was determined by fluorescence activated cell sorting. Immunofluorescence was performed using Annexin-V staining and fluorescein isothiocyanate (FITC). Mitochondrial membrane potential (MMP) was measured using MitoTrackerTM Red. RESULTS: CINO at 0.5 MUM inhibited SK-OV-3, CRL 1978, and CRL-11731 proliferation, migration, and invasion. Each cell type differed in response to CINO doses for PCNA, Annexin-V expression and MMP. CONCLUSION: The antineoplastic property of CINO is consistent, but its mode of action varies among cell lines. PMID- 30275193 TI - Identification of Two Types of Stem Cells in Methylene Blue-stained Sections of Untreated and Diethylstilbestrol-treated Human Prostate Cancer and Their Characterization by Immunogold Localization of CD133. AB - BACKGROUND: The basal compartment of the prostatic acinus harbors stem and basal cells, whereas the luminal compartment contains cuboidal and columnar cells. Mutation in the genes of stem cells is required for benign (normal) prostate to develop into prostatic adenocarcinoma. Stem/basal cells survive androgen deprivation therapy in humans and castrated mice to repopulate glandular cells by proliferation when stimulated by androgen. We hypothesized that using different embedding and staining methods, it would be possible to identify two types of stem cells in human prostate by localization of CD133. MATERIALS AND METHODS: Prostate biopsy or prostatectomy pieces from 13 untreated and eight diethylstilbestrol-treated men with prostate cancer were sectioned, stained by methylene blue and CD133 was localized by immunogold technique. RESULTS: Methylene blue stained basic proteins in dark basal cells, but not in light cells. Light basal cells expressed androgen receptors and dark cells estrogen receptors. Light and dark cells expressed CD133, indicating them to be stem cells. Light stem cells produced the lineage of columnar/cuboidal cells. Estrogen dependent dark cells produced a lineage of columnar/cuboidal cells, that also expressed estrogen receptors. CONCLUSION: Our analysis indicates that stem/basal cells are privileged cells in the basal compartment. Stem cells are not under the regulation of steroid hormones, whereas their lineage of cuboidal/columnar cells are. The lineage of androgen-dependent cells are columnar/cuboidal cells and the lineage of estrogen-dependent cells are also columnar/cuboidal cells. Epon embedding and methylene blue staining showed two types of CD133-positive stem cells in prostate. Paraffin sections did not show two types of stem cells in prostate and bone marrow leukemia cells. Our study indicates the continuity of embryonic stem cells into adult prostate as organ-specific stem cells. To our knowledge, this is the first study to identify two types of stem cells in human prostate. PMID- 30275194 TI - Differential Mobility of Breast Cancer Cells and Normal Breast Epithelial Cells Under DC Electrophoresis and Electroosmosis. AB - BACKGROUND/AIM: Breast cancer has shown improved prognosis over the years, yet due to different types of breast cancer and different phenotypes of breast cancer cells, it is essential to have an accurate diagnostic procedure. MATERIALS AND METHODS: A unique methodology employing direct current (DC) electrophoresis and electroosmosis in fabricated microfluidic devices was used. This phenomenon was used to discern breast cancer cells from normal breast epithelial cells based on their electrophoretic mobility and electroosmosis. RESULTS: Breast cancer cells (MDA-MB-231) rapidly covered the wound in scratch assay compared to mammary epithelial cells (MCF-10A). However, under DC electrophoresis and electroosmosis MCF-10A cells were observed to move at higher velocities compared to MDA-MB-231 cells under similar voltages. CONCLUSION: Our study provides an economical and efficient method of studying electrophoretic and electrokinetic phenomenon of different cell types that can be used to the advantage of detecting and monitoring cancer progression. PMID- 30275195 TI - Increased Soluble PD-L1 Levels in the Plasma of Patients with Epithelial Ovarian Cancer Correlate with Plasma Levels of miR34a and miR200. AB - BACKGROUND: Recently, programmed cell death protein 1 (PD1) blocking and anti programmed death-ligand 1 (PD-L1) agents were approved for the treatment of various human malignancies. MATERIALS AND METHODS: Our study examined the expression of PD-L1 in neoplastic tissue (17 patients) and the plasma soluble (s)PD-L1 of 32 patients with ovarian carcinoma, in parallel with the levels of specific microRNAs (miRs), using immunohistochemistry, enzyme-linked immunosorbent assay (ELISA) and real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR), respectively. RESULTS: PD-L1 levels were significantly higher in the plasma of patients with ovarian cancer compared to healthy women (p=0.01). High miR200 levels were related to high sPD-L1 levels (p=0.03), whilst high miR34a levels were associated with low sPD-L1 levels (p=0.02). Immunohistochemical expression of PD-L1 by cancer cells was not related to plasma miR levels, nor to the level of sPD-L1. CONCLUSION: As well as cancer cell expression of PD-L1, a high sPD-L1 level characterizes a subset of patients with ovarian cancer. The value of this latter feature as a biomarker for the administration of anti-PD-L1/PD1 therapy needs further evaluation. Micro-RNAs, such as miR34a and miR200, may have a role in the efficacy of immunotherapy. PMID- 30275196 TI - Up-regulation of Bone Morphogenetic Protein 7 by 2-Hydroxycinnamaldehyde Attenuates HNSCC Cell Invasion. AB - BACKGROUND/AIM: Few studies have examined the effect of 2'-hydroxycinnamaldehyde (HCA) on head and neck squamous cell carcinoma (HNSCC) cell invasion. This study examined the role of BMP7 on the anti-migration and anti-invasion activity of HCA using HNSCC cells. MATERIALS AND METHODS: Matrigel invasion and wound healing assays were conducted to investigate cell migration or invasion. BMP7 overexpression vector or siRNA mixture was used for transient regulation of gene expression. RESULTS: HCA attenuated HNSCC cell migration and spheroids Matrigel invasion without cytotoxicity. mRNA and protein expression of BMP7 increased with HCA treatment. Exogenous BMP7 overexpression without HCA treatment attenuated Matrigel invasion of cells. Furthermore, suppression of BMP7 by siRNA alleviated the inhibitory effect of HCA on the invasion of Matrigel by the cell, indicating that BMP7 is responsible for the anti-migration effect of HCA in HNSCC cells. CONCLUSION: HCA treatment led to a remarkable up-regulation of BMP7, which resulted in the attenuation of HNSCC cell invasion. PMID- 30275197 TI - Proteomic Identification of FLT3 and PCBP3 as Potential Prognostic Biomarkers for Pancreatic Cancer. AB - BACKGROUND/AIM: Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest types of cancer, particularly due to its aggressive course and challenging diagnostics in early-stage disease. The aim of this study was to discover new potential prognostic and diagnostic pancreatic cancer biomarkers. MATERIALS AND METHODS: The proteomes of 37 samples from pancreatic cancer, inflammatory or healthy pancreatic tissue derived through in-depth differential proteomic analysis were compared. RESULTS: A set of candidate proteins as pancreatic cancer specific diagnostic or prognostic biomarkers were identified. Survival data of patients after two-year follow-up indicated FLT3 and PCBP3 proteins as potential biomarkers for favourable pancreatic cancer prognosis. The levels of PCBP3 correlated with tumour stage and FLT3 levels, were evaluated as independent prognostic marker. CONCLUSION: FLT3 and PCBP3 represent potential biomarkers for improved individualized pancreatic cancer prognosis. Moreover, FLT3 may play a role in future treatment selection. PMID- 30275198 TI - X-ray as Irradiation Alternative for K562 Feeder Cell Inactivation in Human Natural Killer Cell Expansion. AB - BACKGROUND/AIM: gamma-Irradiation has been proven to be the most effective method to inactivate K562 cells, but gamma-irradiators are not available in some institutes. This study was designed to compare the effects of X-ray and gamma irradiation on K562 cells in natural killer (NK) cell expansion. MATERIALS AND METHODS: To expand NK cells, isolated peripheral blood mononuclear cells (PBMCs) were co-cultured with gamma-irradiated or X-ray-treated K562 cells plus IL-2 and IL-15. Characteristics of expanded NK cells were identified by flow cytometry. RESULTS: NK cell expansion rate tended be to lower in the X-ray-treated group (68.9+/-32.6) than the gamma-irradiated group (78+/-28.7), but the difference was not significant (p=0.39). Furthermore, NK cell functions or receptor expression were similar in the two groups. CONCLUSION: Our results suggest that X-ray treatment can be used as an alternative to gamma-irradiation for K562 cells inactivation in human NK cell expansion. PMID- 30275200 TI - High Efficacy of Intravenous Gimatecan on Human Tumor Xenografts. AB - BACKGROUND/AIM: The lipophilic, orally bioavailable camptothecin analogue gimatecan is characterized by improved efficacy over conventional camptothecins on human tumor xenografts. Gimatecan produced excellent outcomes orally with prolonged, low-dose, daily treatments. The aim of this study was to assess the antitumor efficacy of i.v. administered gimatecan. MATERIALS AND METHODS: The antitumor activity of gimatecan delivered i.v. q4dx4 was evaluated in nude mice bearing human tumors and compared to clinically available anticancer drugs. RESULTS: Intravenous administration of gimatecan showed superior efficacy with remarkable achievements at well tolerated doses. Moreover, prolonged treatments with i.v. administered gimatecan showed efficacy in models of cancer refractory to current therapeutic approaches, like an orthotopic brain tumor. CONCLUSION: Although the oral route is practical for gimatecan administration, the results support the interest in developing a suitable i.v. formulation in an attempt to further exploit the therapeutic potential of the compound. PMID- 30275199 TI - Autophagic Gene Polymorphisms in Liquid Biopsies and Outcome of Patients with Metastatic Clear Cell Renal Cell Carcinoma. AB - BACKGROUND/AIM: Autophagy has been shown to be involved in cancer development and response to cancer therapy. In this study, genotypes of autophagic genes were analyzed to assess their correlation with the risk of clear cell renal cell carcinoma (ccRCC) and the outcome of patients treated with pazopanib for metastatic ccRCC. MATERIALS AND METHODS: Single nucleotide polymorphisms (SNPs)were selected in the following genes: ATG4A (rs7880351), ATG4B (rs6709768), ATG4C (rs2886770, rs6670694, rs6683832), ATG5 (rs9373839, rs3804333, rs490010), ATG16L1 (rs6752107), ATG16L2 (rs10751215) and IRGM (rs10059011). The Kaplan-Meier method and log-rank test were used to evaluate differences between groups. RESULTS: Forty patients with metastatic ccRCC treated with pazopanib were included in the analysis. ATG16L2rs10751215 was significantly less frequent in patients with ccRCC compared to the general population, suggesting its potential protective role, while ATG4Ars7880351, ATG4C rs6670694 and rs6683832 and ATG5 rs490010 were correlated with the progression-free survival (PFS) of patients treated with pazopanib. CONCLUSION: Our results suggest, for the first time, that autophagic gene SNPs are associated with ccRCC risk and patient outcome. PMID- 30275201 TI - Kisspeptin Inhibits Colorectal Cancer Cell Invasiveness by Activating PKR and PP2A. AB - BACKGROUND/AIM: The aim of the present study was to investigate the mechanism through which kisspeptin inhibits colorectal cancer metastasis. MATERIALS AND METHODS: Colorectal cancer cells were treated with kisspeptin and then subjected to assays for cell viability, migration, invasion and anchorage-independent growth. Kisspeptin receptor (KISS1R) requirement was examined by siRNA-based gene silencing followed by western blot and invasion assays. Kisspeptin regulation of PKR and PP2A was examined by treating cells with inhibitors for PKR or PP2A. RESULTS: Kisspeptin inhibited colorectal cancer cell invasiveness without affecting cell proliferation. Kisspeptin required activation of KISS1R and resulted in activation of PKR and PP2A. PKR inhibitor blocked kisspeptin-induced PP2A phosphorylation, while PP2A inhibitor failed to block kisspeptin-induced PKR phosphorylation. CONCLUSION: Kisspeptin-mediated activation of PKR-PP2A inhibited colorectal cancer cell invasiveness. PMID- 30275202 TI - 4-Methylumbelliferone Decreases the Hyaluronan-rich Extracellular Matrix and Increases the Effectiveness of 5-Fluorouracil. AB - BACKGROUND/AIM: Pancreatic cancer responds poorly to most chemotherapeutic agents. Several studies have reported that hyaluronan (HA)-rich extracellular matrix (ECM) is a biological barrier against chemotherapeutic agents. 4 methylumbelliforone (MU) led to inhibition of HA synthesis and its preservation in ECM, which may enhance 5-fluorouracil (5-FU) cytotoxicity. Thus, new therapy with MU and 5-FU may be developed for pancreatic cancer. MATERIALS AND METHODS: A 5-fluorouracil (5-FU) concentration and 4-methylumbelliferone (MU) dosage was analyzed by high-performance liquid chromatography (HPLC). Change in antitumor efficacy of 5-FU in combination with MU was also examined in vivo and in vitro. RESULTS: Combined 5-FU and MU treatment inhibited cell proliferation better than 5-FU alone; 0.01 mM 5-FU alone decreased cell proliferation by 37.7 %, while 0.01 mM 5-FU with 0.5 mM MU decreased cell proliferation by 57.4%. MU enhanced the intracellular concentration of 5-FU by 47.3% compared to control. Mice tumors treated with 5-FU and MU decreased in size and animal survival was prolonged. Moreover, MU decreased cohesiveness of the intercellular space. CONCLUSION: Combination therapy of 5-FU with MU was effective. A novel therapy can be designed for pancreatic cancer by using ECM modulation. PMID- 30275203 TI - Comparative p16IKN4A Expression in Laryngeal Carcinoma and Cervical Cancer Precursors: A Real-time Grid-based Immunocytochemistry Analysis. AB - BACKGROUND/AIM: p16 (gene locus: 9p21) tumor suppressor gene is considered an important biomarker for the progression and prognosis in a variety of malignancies and pre-cancerous lesions, including high-risk (HR-) human papilloma virus (HPV)-mediated squamous intraepithelial lesions (SILs), based on cytological and the corresponding cervical intraepithelial neoplasia (CIN) histopathological categorization. p16 acts as a cyclin-dependent kinase-4 inhibitor negatively regulating the cell cycle. In persistent HPV infection, E7 oncogenic protein binds retinoblastoma protein leading to its proteolytic transformation, also triggering E2F dissociation, which increases DNA transcription and progression to S phase. This mechanism promotes aberrant p16 over-expression. Our aim was to comparatively analyze p16 protein expression patterns in laryngeal squamous cell carcinomas (LSCC) and also in SILs. MATERIALS AND METHODS: Fifty (n=50) primary LSCCs tissues all non-HPV-dependent, and a set of 50 liquid-based SILs, were analyzed by immunohistochemistry and immunocytochemistry, respectively. Concerning the screening process in cytological slides, a novel real-time reference and calibration grid platform was implemented and employed. RESULTS: Decreased protein expression was observed in 34/50 (68%) tissues regarding LSCCs. Overall p16 expression was associated to smoking status of the patients (p=0.001), and also with the p-stage of the examined malignancies (p=0.033). A strong statistical significance was assessed correlating LSIL/HSIL cases with a progressive p16 over expression (p=0.001), also reflecting a higher CIN diagnosis (p=0.001). CONCLUSION: p16 down-regulation is a frequent genetic event in LSCCs, which is associated with advanced disease. In contrast to this, p16 over-expression triggered by a specific molecular mechanism shows a strong relationship with a progressively aggressive phenotype due to upgraded SIL/CIN cervical categorization. The first described application of the grid platform demonstrated a considerable improvement in the immunocytochemistry slide screening process enhancing the diagnostic reliability. PMID- 30275204 TI - Hard Palate Melanoma: A Population-based Analysis of Epidemiology and Survival Outcomes. AB - BACKGROUND/AIM: Hard palate melanoma is an extremely rare and aggressive tumor arising from the mucosal epithelium of the oral cavity. The aim of this study was to analyze epidemiology, loco-regional treatment patterns and survival outcomes of this disease. MATERIALS AND METHODS: The National Cancer Institute's Surveillance Epidemiology and End Results (SEER) database was searched for all cases of hard palate melanoma diagnosed between 1973 and 2012. The Kaplan-Meier method was used to calculate overall survival rate, log-rank test to compare survivals of different subgroups, and Cox hazard regression analysis to determine independent predictors of overall survival. RESULTS: Overall, 83 patients were identified, 49 female and 34 males. The distribution among ages was: 13.3% <50 years, 38.6% between 50 and 69 years, 48.2% >=70. Surgery alone was applied in 48.2% of patients, radiation therapy alone in 6%, and combination of surgery and radiation therapy in 33.7%. Overall 5-year survival was 26.3%. Survival with adjuvant radiation therapy was not longer than with surgery alone. CONCLUSION: Hard palate melanoma is a rare malignancy mostly affecting the elderly, with low overall survival. The main treatment is surgical resection, while adjuvant radiotherapy does not improve survival. The establishment of an international registry is warranted to better define treatment options. PMID- 30275205 TI - De Novo Myelodysplastic Syndrome and Subsequent Diagnosis of Primary Solid Tumors: Evidence from the National Cancer Institute 2001-2011. AB - BACKGROUND: To our knowledge there are no population-level studies on the association between non-treatment-related myelodysplastic syndrome (MDS) and subsequent primary solid tumors. MATERIALS AND METHODS: Adult patients diagnosed with non-treatment-related MDS were selected from the SEER 18 database and the risk of subsequent primary solid tumor was calculated. RESULTS: A total of 40,780 patients with a diagnosis of MDS were reported in the SEER 18 registry during 2001 to 2011. In these patients, 2,111 subsequent primary solid tumors were diagnosed with an observed/expected (O/E) ratio of 1.16 and an absolute excess risk of 26.86 per 10,000. Diagnosis of subsequent solid tumor was most likely immediately after diagnosis of MDS or within 1 year of diagnosis. CONCLUSION: The risk of diagnosis of primary solid tumor malignancy in adult patients with de novo MDS is significantly higher compared to the general population. It is unclear whether this is due to detection bias or underlying pathophysiology. PMID- 30275206 TI - Suboptimal Outcomes in Cutaneous Squamous Cell Cancer of the Head and Neck with Nodal Metastases. AB - BACKGROUND/AIM: There are limited data regarding survival, failure patterns, and factors associated with disease recurrence in patients with cutaneous squamous cell cancer of the head and neck (cSCC-HN) with nodal metastases. PATIENTS AND METHODS: A retrospective analysis of patients with cSCC-HN metastatic to cervical and/or parotid lymph nodes treated with surgery and post-operative radiation therapy was performed. RESULTS: This study included 76 patients (57 immunocompetent and 18 immunosuppressed) with a median follow-up of 18 months. Overall survival, disease-free survival (DFS), and disease recurrence (DR) at 2 years was 60%, 49%, and 40%, respectively. Immunosuppressed patients had significantly lower 2-year DFS (28% vs. 55%; p=0.003) and higher DR (61% vs. 34%; p=0.04) compared to immunocompetent patients. Analysis of immunocompetent patients demonstrated extracapsular extension (ECE) as the only factor associated with DR (p<0.0001). CONCLUSION: Patients with nodal metastases from cSCC-HN have suboptimal outcomes. ECE and immunosuppression were significantly associated with DR. PMID- 30275207 TI - Report of Objective Clinical Responses of Cancer Patients to Pharmaceutical-grade Synthetic Cannabidiol. AB - BACKGROUND/AIM: Cannabinoids are widely used in the management of pain, nausea and cachexia in cancer patients. However, there has been no objective clinical evidence of any anticancer activity yet. The aim of this study was to assess the effects of pharmaceutical-grade synthetic cannabidiol on a range of cancer patients. PATIENTS AND METHODS: We analysed the data routinely collected, as part of our treatment program, in 119 cancer patients over a four-year period. RESULTS: Clinical responses were seen in 92% of the 119 cases with solid tumours including a reduction in circulating tumour cells in many cases and in other cases, a reduction in tumour size, as shown by repeat scans. No side-effects of any kind were observed when using pharmaceutical grade synthetic cannabidiol. CONCLUSION: Pharmaceutical-grade synthetic cannabidiol is a candidate for treating breast cancer and glioma patients. PMID- 30275208 TI - Roux-en-Y Plus Distal Jejunal Pouch After Total Gastrectomy: A Prospective Study. AB - BACKGROUND/AIM: We previously described the safety of distal jejunal pouch with Roux-en-Y reconstruction after total gastrectomy. The present prospective study evaluated its clinical benefit. PATIENTS AND METHODS: Forty-five patients with gastric cancer were preoperatively assigned to groups who underwent Roux-en-Y reconstruction with jejunal pouch (PRY) (n=23) or without pouch (RY) (n=22). Age, sex, grade of lymph node dissection, splenectomy and mode of laparotomy were analyzed, and body mass index (BMI), volume of food intake at one sitting and blood chemistry (total protein, hemoglobin, iron and cholesterol) were periodically assessed in both groups. RESULTS: Post-surgical mortality and severe morbidity did not occur. Three and four patients in the PRY and RY groups, respectively, died of gastric cancer recurrence during the study. BMI at six months after surgery was significantly higher in the PRY than in the RY group (p<0.05). The percentage of food intake at one year after the procedure was significantly higher in the PRY than in the RY group (p<0.05). CONCLUSION: The distal jejunal pouch ameliorated postoperative weight loss and increased food intake. A distal jejunal pouch with PRY reconstruction may confer significant clinical advantages after total gastrectomy. The long-term clinical benefit of this procedure should be evaluated. PMID- 30275209 TI - Cholangiocarcinoma: CT-guided High-Dose Rate Brachytherapy (CT-HDRBT) for Limited (<4 cm) and Large (>4 cm) Tumors. AB - BACKGROUND/AIM: Thermal-ablative therapies are limited to tumors of 3-4 cm diameter. The purpose of this study was to evaluate the local tumor control (LTC) of CT-guided High-Dose-Rate-Brachytherapy (CT-HDRBT) for ablation of cholangiocarcinomas (CCA) >=4 cm compared to smaller tumors. PATIENTS AND METHODS: Sixty-one patients (tumors: 142, interventions: 91) were treated from March 2008 to January 2017. LTC, progression-free survival (PFS) and overall survival (OS) after first CT-HDRBT were identified for two subgroups (A:<4 cm, B:>=4 cm) and the influence of coverage and target-dose were evaluated. Log-Rank- and Mann-Whitney-U-Tests were performed for statistical analyses with p-values <0.05 considered as significant. RESULTS: Better coverage was achieved for smaller tumors (A: 99.22-0.25%, B: 95.10-1.40%, p<0.001). LTC was better in subgroup A (A: 8, B: 6 months, p=0.006). Larger tumors (4-7 cm) with incomplete coverage showed the poorest LTC (p=0.032). There were no statistical significances in PFS (A: 5, B: 3 months, p=0.597) and OS (A:15.5; B:10.0 months, p=0.107). CONCLUSION: CT-HDRBT is sufficient in CCA >=4 cm, if full coverage with therapeutic doses can be achieved. PMID- 30275210 TI - Impact of Body Mass Index (BMI) on Chemotherapy-associated Toxicity in Ovarian Cancer Patients. A Pooled Analysis of the North-Eastern German Society of Gynecological Oncology (NOGGO) Databank on 1,213 Patients. AB - BACKGROUND/AIM: Chemotherapy-associated toxicity is one of the limiting factors regarding treatment efficacy, patient outcome and quality of life in this collective. Underweight or obese patients represent a major group in which the therapy seems to be more challenging. The aim of this analysis was to evaluate the impact of BMI on the toxicity in patients undergoing chemotherapy. PATIENTS AND METHODS: The data of three prospective phase II/III studies ('Tower', 'Topotecan phase III' and 'Hector') of the North-Eastern German Society of Gynecological Oncology including 1,213 patients with recurrent ovarian cancer were retrospectively analyzed. The study was performed using logistic regression and Cox regression analysis. RESULTS: The median age at diagnosis was 59 years. Sixty-seven (5.5%) patients had BMI <20 and 272 (22.4%) patients had BMI >30. Preterm termination of the chemotherapy was associated with lower BMI (p=0.017). Moreover, non-hematological toxicity grade III/IV was mainly observed in underweighted women as well (p<0.001). Patients with higher BMI more often presented with grade III/IV anemia (p=0.019) and as a consequence required blood transfusions more frequently (p=0.005). The overweight group was also associated with a higher number of co-medications. However, no difference in survival regarding BMI was observed in our study. CONCLUSION: Fewer chemotherapy cycles and preterm discontinuation were more frequent in patients with lower BMI. Hematological toxicity and higher medication intake appeared more often in patients with higher BMI. PMID- 30275211 TI - Baseline Sarcopenia and Skeletal Muscle Loss During Chemotherapy Affect Survival Outcomes in Metastatic Gastric Cancer. AB - AIM: To determine the association between sarcopenia and prognosis in patients with metastatic gastric cancer (mGC) receiving chemotherapy. PATIENTS AND METHODS: Our study retrospectively evaluated 231 consecutive Japanese patients with mGC who commenced first-line chemotherapy at our Institution between January 2013 and December 2015. Muscle loss during chemotherapy was defined as a >=10% reduction in the skeletal muscle index and was evaluated for its association with time to treatment failure (TTF) and overall survival (OS). RESULTS: Of 118 patients, 89% had baseline sarcopenia and 31% developed muscle loss. Muscle loss was significantly associated with shorter TTF and OS and was an independent prognostic factor for both these parameters; poor performance status and poorer differentiation on histology were also significant predictors of shorter OS. However, muscle loss was not significantly associated with increased grade 3 or higher toxicities. CONCLUSION: Muscle loss during chemotherapy negatively affected survival among patients with mGC. PMID- 30275212 TI - Current and Future Use of Radiological Images in the Management of Gynecological Malignancies - A Survey of Practice in the UK. AB - BACKGROUND/AIM: Radiology provides increasingly accurate and complex information. Understanding the clinicians' interpretation of scans could improve surgical planning, decision-making; informed training and development of augmented imaging. This was a survey exploring the interpretation of imaging by clinicians and its use in operative preparation and prediction. MATERIALS AND METHODS: The survey was open for two-months and circulated online to British Gynaecological Cancer society members. RESULTS: Seventy-three (19%) members completed the survey. Respondents had a confidence level of 51% in their ability to interpret computed tomography (CT) and/or magnetic resonance imaging (MRI) images independently. Preoperative imaging was commonly used to plan operations, predict complications and complete resection. Images were reviewed for primary (96.3%)/interval (92.6%) ovarian debulking, but less so for vulvectomy (45%). Scan (79.6%) and multidisciplinary team meeting (MDT) (66.6%) reports were used more often than scan images (50%) for operative planning. Amount and pattern of disease on scan were the most important factors predicting operating time. CONCLUSION: Imaging influences the surgeon's planning, however respondents lack confidence. Training of clinicians in radiological interpretation needs to improve. Augmented image interfaces could facilitate this. PMID- 30275214 TI - Relationship Between CA 19.9 and the Lewis Phenotype: Options to Improve Diagnostic Efficiency. AB - BACKGROUND/AIM: Approximately 10% of patients are unable to synthesize CA 19.9 (Lewis-negative), and these results are erroneously considered false-negatives. The aim of this study was to confirm that CA 19.9 cannot be detected by immunoassays in Lewis-negative patients. MATERIALS AND METHODS: CA 19.9 levels were measured by immunological assays and Lewis phenotype was determined by the haemagglutination reaction. RESULTS: Patients with Lewis phenotype (a+b-) or (a b+) had significantly higher CA 19.9 levels than Lewis-negative patients with active cancer (p<0.001), no-evidence of disease (NED) patients (p<0.001) or patients with benign disease (p<0.001). Ninenty-four percent of patients (33/35) with undetectable CA 19.9 had a Lewis-negative phenotype. Additionally, 94.7% (34/36) of patients with Lewis-negative phenotypes had undetectable CA 19.9 serum levels. CONCLUSION: Patients with undetectable CA 19.9 serum levels tend to be Lewis-negative, and CA 19.9 is not useful in diagnosis or follow-up. PMID- 30275213 TI - Different Timing to Use Bevacizumab in Patients with Recurrent Glioblastoma: Early Versus Delayed Administration. AB - BACKGROUND/AIM: In patients with recurrent glioblastoma, the best timing to administer bevacizumab is not well addressed yet. In this study, we reported the results of a monocentric experience comparing the early use of bevacizumab (following the first GBM recurrence) with the delayed administration (following the second or even further GBM recurrences). MATERIALS AND METHODS: This analysis included 129 glioblastoma patients with a median follow-up of 22.4 months (range=5.26-192 months). RESULTS: The median time lapse from diagnosis of glioblastoma to disease recurrence was 11.6 months; 13.1 for patients treated with deferred administration of bevacizumab and 9.9 for patients with early administration (p=0.047). Bevacizumab progression-free survival with early and delayed use was 3.45 and 2.92 months, respectively (p=0.504). Survival time from the start of bevacizumab was 6.18 months in patients with early administration, and 6.47 in the delayed administration one (p=0.318). CONCLUSION: Delayed administration of bevacizumab can be considered in selected patients with less aggressive recurrent glioblastoma. PMID- 30275215 TI - Prognostic Significance and Clinicopathological Features of Synchronous Colorectal Cancer. AB - AIM: This study aimed to clarify the difference in the clinicopathological and prognostic features between synchronous colorectal cancer (CRC) and solitary CRC. MATERIALS AND METHODS: A retrospective analysis was conducted in patients with synchronous and solitary CRC. RESULTS: A total of 92 (7.1%) out of 1,295 consecutive patients had synchronous CRC. Mucinous adenocarcinoma was more frequent in patients with synchronous CRC than in those with solitary CRC (13.0% vs. 3.7%; p<0.001). The 5-year relapse-free survival (RFS) rate was poorer in patients with synchronous CRC than in those with solitary CRC (65.3% vs. 75.1%; p=0.035), which was contrived by the multivariate analysis (hazard ratio=1.52(HR); p=0.039). CONCLUSION: Patients with synchronous CRC had a poorer RFS than those with solitary CRC; thus, patients with synchronous CRC might require more intensive care than those with solitary CRC in follow-up. PMID- 30275216 TI - PD-L2 Expression as a Potential Predictive Biomarker for the Response to Anti-PD 1 Drugs in Patients with Non-small Cell Lung Cancer. AB - BACKGROUND/AIM: To investigate the role of programmed cell death-ligand 2 (PD-L2) expression as a predictive biomarker for response to anti-programmed cell death-1 (PD-1) drugs in patients with non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Ten patients who had undergone curative lung resection and received the anti-PD-1 drugs for the recurrence were enrolled. The cut-off value for PD-L2 (antibody clone 176611) expression on tumor cells was set at 50%. Tumor response was evaluated according to immune-related response criteria. RESULTS: Seven patients (70.0%) were positive for PD-L2. The response rates were 28.6% (2/7) and 33.3% (1/3) in patients with PD-L2-positive and PD-L2-negative NSCLC, respectively. Disease control was obtained in 2 patients despite the programmed cell death-ligand 1 (PD-L1)-negativity (antibody clone 22C3: 0%, antibody clone SP142: 0%), and these tumors expressed PD-L2 (>=1%). CONCLUSION: PD-L2 expression may be a target of immunotherapy in patients with PD-L1-negative NSCLC. PMID- 30275217 TI - Prognostic Impact of PD-L2 Expression and Association with PD-L1 in Patients with Small-cell Lung Cancer. AB - BACKGROUND/AIM: Although some previous studies suggested that programmed cell death-ligand 1 (PD-L1) expression was significantly associated with a favorable postoperative prognosis in patients with small-cell lung cancer (SCLC), the prognostic significance of PD-L2 expression remains unknown. The aim of the current study was to investigate the prognostic significance of PD-L2 expression in patients with SCLC. PATIENTS AND METHODS: Thirty-eight patients who underwent resection of SCLC were analyzed. A monoclonal anti-human PD-L1 antibody (clone SP142) and a monoclonal anti-human PD-L2 antibody (clone 176611) were used as the primary antibodies. Cut-off value for PD-L1 and PD-L2 expression was set to 1%. RESULTS: Among 38 patients, 15 (39.5%) were positive for PD-L2 expression. No significant associations between PD-L2-positivity and clinicopathological factors, including PD-L1 positivity or prognosis were identified. No significant differences in disease-free survival and overall survival were observed between PD-L2-positive patients and PD-L2-negative patients (p=0.367 and p=0.726, respectively). CONCLUSION: PD-L2 expression is not related to clinicopathological factors or postoperative prognosis in patients with SCLC, though this should be further investigated in studies involving larger populations. PMID- 30275218 TI - SUVmax-based Parameters of FDG-PET/CT Reliably Predict Pathologic Complete Response After Preoperative Hyperthermo-chemoradiotherapy in Rectal Cancer. AB - BACKGROUND/AIM: To determine the most reliable predictor for pathologic complete response (pCR) in patients who underwent preoperative chemoradiotherapy and regional hyperthermia (HCRT) for rectal cancer. PATIENTS AND METHODS: Thirty-six patients were enrolled. The local control status of the patients was assessed using 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT), magnetic resonance imaging (MRI), and colonoscopy before and after HCRT. The relationships between various parameters of these clinical examinations and pCR were analyzed. RESULTS: Ten (28%) patients achieved pCR. The accuracies of predicting pCR using FDG-PET/CT, MRI, and colonoscopy were 78%, 61%, and 75%, respectively. FDG-PET/CT was the only independent predictive modality for pCR (p=0.021). The maximum standardized uptake value (SUVmax) and SUVmax normalized to liver uptake (SLR) after HCRT showed the highest sensitivity (90%) and the decreasing rate of SUVmax and SLR demonstrated the highest specificity (89%) for pCR. CONCLUSION: SUVmax-based parameters of FDG-PET/CT after HCRT were the most reliable predictors for pCR. PMID- 30275219 TI - Long-term Survival and Propensity Score Matched Outcomes of Bilateral vs. Unilateral Diaphragm Interventions in Cytoreductive Surgery plus Intra-peritoneal Chemotherapy. AB - BACKGROUND/AIM: To assess the impact of short- and long-term outcomes of bilateral vs. unilateral diaphragm interventions in cyto-reductive surgery (CRS) and intra-peritoneal chemotherapy (IPC). PATIENTS AND METHODS: A total of 652 CRS/IPC procedures, between 1996 and 2018, required diaphragm interventions. Among these, 388 underwent bilateral intervention. Preoperative heterogeneity was assessed in 6 parameters and addressed with propensity score matching. The association of each respective analysis was assessed with 11 outcomes. Overall survival was assessed based on histology. RESULTS: CRS/IPC requiring bilateral diaphragmatic interventions illustrated significantly increased operative hours (9.6 vs. 8.6 hours, p<0.001). Postoperatively, there was significantly increased red blood cell (RBC) transfusion (6.37 units vs. 4.47 units, p=0.007) and grade III and IV complications (57.3% vs. 40.6%, p=0.004). No difference was noted in ICU stay, total length of stay, hospital death and return to OT. In terms of respiratory complications, an increased incidence of pneumothorax (16.5% vs. 6.2%, p<0.001) was noted whilst pleural effusions and pneumonia occurrences were non-significant. Overall survival, revealed bilateral interventions in low-grade appendiceal mucinous neoplasm conferred an increased relative risk (p=0.037, RR=2.230, 95%CI=1.052-4.730). They did not have an effect on OS in colorectal cancer and mesothelioma. CONCLUSION: Despite the increase in short-term morbidity, bilateral diaphragm interventions resulted in similar long-term survival to unilateral interventions. PMID- 30275220 TI - Detection of KK-LC-1 Protein, a Cancer/Testis Antigen, in Patients with Breast Cancer. AB - BACKGROUND: Kita-Kyushu lung cancer antigen-1 (KK-LC-1) is a cancer/testis antigen and predominant target for cancer immunotherapy. Its detection is only established based on gene expression. In this study, we established a monoclonal antibody against KK-LC-1 to detect its protein expression in formalin-fixed samples. MATERIALS AND METHODS: The monoclonal antibody against KK-LC-1 was evaluated and the detection of KK-LC-1 between gene expression and protein expression was compared in patients with breast cancer. The monoclonal antibody clone 34B3, which we established, stained testicular germ cells positively. RESULTS: The rates of detection of KK-LC-1 gene and protein expression were 11.8% and 52.9%, respectively. Protein expression was detected in all triple-negative breast cancer cases studied (n=8). Furthermore, KK-LC-1 was detected in all tumours without oestrogen receptor expression. CONCLUSION: This study indicated that KK-LC-1 expression was detected in breast cancer, especially in oestrogen receptor-negative subtypes. PMID- 30275221 TI - Serum DHEA-S Is a Predictive Parameter of Abiraterone Acetate in Patients with Castration-resistant Prostate Cancer. AB - BACKGROUND/AIM: There is no definitive biomarker that predicts the effectiveness of abiraterone acetate. The objective of this study was to investigate whether dehydroepiandrosterone sulfate (DHEA-S) predicts the effectiveness of abiraterone acetate. MATERIALS AND METHODS: This study included a total of 28 consecutive patients. The optimal cutoff value of DHEA-S for predicting the PSA response was calculated by receiver operating characteristic (ROC) analysis. The Cox proportional hazards model was performed to determine the predictive factors for the susceptibility to abiraterone acetate. RESULTS: Serum DHEA-S at baseline intercorrelated with the PSA response (correlation coefficient: -0.516). The optimal cutoff value of serum DHEA-S at baseline was 47.4 ug/dl in predicting >50% PSA decline. Serum PSA and serum DHEA-S at baseline were identified as significant factors for predicting PSA progression-free survival (p=0.010 and p=0.003, respectively). CONCLUSION: Serum DHEA-S at baseline may be a biomarker for predicting the prognosis of CRPC patients treated with abiraterone acetate. PMID- 30275222 TI - Preexisting Interstitial Lung Disease and Lung Injury Associated with Irinotecan in Patients with Neoplasms. AB - BACKGROUND/AIM: The aim of this study was to reveal risk factors for lung injury following irinotecan administration for the treatment of neoplasms. PATIENTS AND METHODS: This study included 204 patients who received irinotecan from October 2005 to November 2014 and had evaluable chest CT images before initiation of irinotecan. RESULTS: Six (2.9%) patients developed lung injury and, of these, 2 had preexisting interstitial lung disease (pre-ILD). The frequency of lung injury in patients with pre-ILD was 11% (2 of 19) while that in patients without pre-ILD was 2.2%. Risk factor analysis for the lung injury showed pre-ILD was the most predictable factor [odds ratio (OR) 5.00, p=0.07]. Combination with other agents, origin of neoplasms (lung or not), initial dose or minimum interval were not observed to be related to risk. CONCLUSION: The risk of lung injury with irinotecan was high when pre-ILD was present and the risk was comparable with previously reported other agents. PMID- 30275223 TI - Cisplatin Substitution with Carboplatin During Radical Chemoradiotherapy for Oesophagogastric Carcinoma: Outcomes from a Tertiary Centre. AB - BACKGROUND/AIM: Cisplatin-based radical chemoradiotherapy (CRT) is utilised in oesophagogastric (OG) cancer but the toxicity profile of cisplatin limits its use. This study aimed to evaluate the clinical characteristics and outcomes of patients treated with either cisplatin or carboplatin based CRT at our institution. MATERIALS AND METHODS: This is a retrospective analysis of patients with localised OG cancer undergoing CRT with cisplatin/fluoropyrimidine (CX/F) or carboplatin/fluoropyrimidine (CarboX/F) between January 2001 and December 2014. RESULTS: A total of 91 eligible patients were included. Median age was 65 years (IQR=57-75) for CX/F and 77 years (IQR=69-80) for CarboX/F. Adenocarcinoma histology and Charlson comorbidity index were higher in the CarboX/F group. Endoscopic complete response (CR) was achieved in 64% of CX/F group and 48% of CarboX/F group (p=0.19). The median PFS for CX/F was 31.0 months (95%CI=18.2-NE) vs. 18.7 months for CarboX/F (95%CI=13.5-30.4; HR=1.49, p=0.21). CONCLUSION: Despite significant differences in baseline clinical characteristics, patients treated with carboplatin CRT demonstrated no significant difference in PFS or endoscopic CR rate, compared to those treated with cisplatin. PMID- 30275224 TI - Radiation Dose Escalation in Accelerated Hyperfractionated Radiotherapy for Stage III Non-small-cell Lung Cancer. AB - AIM: To identify clinical benefits of dose escalation in accelerated hyperfractionated radiotherapy (AH-RT) for stage III non-small-cell lung cancer (NSCLC) using propensity score-matched (PSM) analysis. MATERIALS AND METHODS: Our study retrospectively examined 294 patients undergoing definitive radiotherapy [131 patients, conventional once-daily radiotherapy (OD-RT); and 163, AH-RT] who were followed-up for a median of 40.4 months. The impact of overall survival (OS), progression-free survival (PFS), and locoregional control (LRC) was investigated. RESULTS: Pre-PSM, the median OS, PFS, and LRC durations were 23.1 vs. 39.9 (p=0.03), 8.9 vs. 13.5 (p<0.01), and 12.9 vs. 50.3 (p<0.01) months in the OD-RT and AH-RT groups, respectively. After-PSM (two matched groups of 144 patients), AH-RT was associated with better LRC [adjusted hazard ratio (aHR)=0.59, 95% confidence interval (CI)=0.33-0.99, p=0.04] and marginally better PFS (aHR=0.65, 95% CI=0.41-1.03; p=0.06), but not OS (aHR=0.75, 95% CI=0.46-1.24; p=0.26). CONCLUSION: After PSM analysis, dose escalation using AH-RT improved LRC and PFS in patients with locally advanced NSCLC. AH-RT can be a promising option for patients with advanced NSCLC. PMID- 30275225 TI - Long-term Follow-up Results of CT-guided Daily Adaptive Radiation Therapy for Localized Prostate Cancer. AB - BACKGROUND/AIM: To examine whether CT-guided daily adaptive radiation therapy (ART) can be safely administered against localized prostate cancer. PATIENTS AND METHODS: Twenty-six patients with localized prostate adenocarcinoma were irradiated through opposed AP/PA fields up to 46 Gy, then CT-guided daily ART was performed through opposed lateral fields until 76 Gy at 2 Gy/fraction. RESULTS: Biochemical relapse-free survival was 89% at 3 years and 85% at 5 years and 76% at 7 years after ART, respectively. The 3-, 5- and 7-year local relapse-free survival rates were 100%, 100% and 95%, respectively. The 5-year incidence rates of grade 1 and 2 late gastrointestinal adverse events were 15.4% (n=4) and 3.8% (n=1), respectively, and those of grade 1 and 2 late genitourinary adverse events were 3.8% (n=1) and 0% (n=0), respectively. CONCLUSION: CT-guided daily ART was well tolerated and suggested a good long-term tumor control with minimal adverse events. PMID- 30275226 TI - Bevacizumab-based Chemotherapy for Poorly-differentiated Neuroendocrine Tumors. AB - AIM: To assess and report the efficacy of and tolerance to bevacizumab-based chemotherapy in treatment outcome of metastatic poorly differentiated neuroendocrine tumors. PATIENTS AND METHODS: From 2007 to 2018, 11 consecutive patients with metastatic poorly differentiated neuroendocrine treated in first- or second-line with bevacizumab-based chemotherapies were included in this monocentric retrospective cohort. Tumor response was evaluated by computed tomographic scans. RESULTS: Administered treatment included 5-fluorouracil and irinotecan (FOLFIRI) bevacizumab, 5-fluorouracil and oxaliplatin (FOLFOX) bevacizumab and 5-fluorouracil, oxaliplatin and irinotecan (FOLFIRINOX) bevacizumab for four, two and five patients, respectively. Three were treated in first-line and eight in second-line after cisplatin-etoposide regimen. Using Response Evaluation Criteria in Solid Tumors, partial response was observed for seven patients, and stable disease for one patient, giving a response rate of 63.6% (95% confidence interval=35.2-92.1%) and disease control rate of 72.7% (95% confidence interval=46.6-99.0%). All patients had died by the time of analysis, median progression-free survival was 14 months, and median overall survival was 15.3 months. Observed toxicity with such protocols was classical with 10 grade 3 4 toxic events, including three of hematological toxicity, three of infection, and three of digestive toxicity. CONCLUSION: Bevacizumab-based chemotherapy gave surprising efficacy and safety in first-or second-line treatment for metastatic poorly differentiated neuroendocrine tumor in this retrospective cohort. Prospective randomized trials of such therapy are warranted. PMID- 30275227 TI - Intraperitoneal Administration of Paclitaxel Followed by Paclitaxel, Cisplatin, and S-1 Chemotherapy for Cytology-positive Gastric Cancer: A Feasibility Study. AB - BACKGROUND/AIM: A preliminary study evaluating the feasibility of single intraperitoneal (IP) administration of paclitaxel followed by paclitaxel and cisplatin with S-1 (PCS) systemic chemotherapy for cytology-positive (CY1) gastric cancer. PATIENTS AND METHODS: Staging laparoscopy was performed to confirm CY1 and P0 status. Initially, patients received IP paclitaxel. Beginning 7 days later PCS was given every 3 weeks followed by second-look laparoscopy. RESULTS: Nine patients were enrolled. The toxic effects of IP and systemic chemotherapy were acceptable. After chemotherapy, 8 patients converted from CY1P0 to CY0P0 and 1 patient from CY1P0 to CY1P1. Gastrectomy was performed on 8 patients except for the CY1P1 patient. Four patients were alive without recurrence. The 2-year overall and progression-free survival rates were 76% and 65%, respectively. CONCLUSION: Combination chemotherapy with IP paclitaxel and sequential PCS is safe and may be effective for CY1 gastric cancer. PMID- 30275228 TI - Intraperitoneal and Systemic Chemotherapy for Patients with Gastric Cancer with Peritoneal Metastasis: A Phase II Trial. AB - AIM: To conduct a phase II study of single intraperitoneal (i.p.) administration of paclitaxel followed by paclitaxel, cisplatin, and S-1 (PCS) chemotherapy for patients with gastric cancer with peritoneal metastasis (PM). PATIENTS AND METHODS: Staging laparotomy was performed to confirm PM. Initially, patients received i.p. paclitaxel. Beginning 7 days later, PCS was given every 3 weeks followed by second-look laparoscopy. Primary and secondary endpoints were the overall survival (OS) rate, and response rate and patient safety, respectively. RESULTS: Seventeen patients were enrolled. The overall response rate was 70.5% (12/17). Grade 3/4 toxic effects included neutropenia and leukopenia. After chemotherapy, PM disappearance was confirmed in 11 patients. Gastrectomy was eventually performed in 11 patients. The 1-year OS rate was 82.4% and the median survival time was 23.9 months considering the overall cohort. CONCLUSION: Combination chemotherapy with i.p. paclitaxel and PCS is well tolerated and effective in patients with gastric cancer with PM. PMID- 30275230 TI - Investigation of Survivin Gene Polymorphism and Serum Survivin Levels in Patients with Brain Tumors. AB - BACKGROUND/AIM: The single nucleotide polymorphism -31C/G identified in the survivin gene promoter seems to be associated with over-expression of survivin, an anti-apoptotic protein. In gliomas, increased survivin expression correlated with decreased survival. The aim of the study was to investigate whether survivin gene polymorphism associates with benign and malignant brain tumors and whether it affects survivin serum levels. PATIENTS AND METHODS: Survivin polymorphism 31C>G was genotyped in 82 patients with brain tumors and 65 healthy controls by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and survivin levels were evaluated by enzyme-linked immuno sorbent assay (ELISA) in patients and controls. RESULTS: Serum survivin levels in patients with malignant tumors were higher than patients with benign tumors (p<0.001). Survivin levels in patients with malignant glial tumors and the frequency of the GG genotype were higher than in patients with benign tumors (p=0.04) and controls (p=0.05). The prevelance of the survivin gene promoter polymorphism -31C>G did not differ between patients and controls. CONCLUSION: Survivin promoter -31C>G gene polymorphism seems to be associated with serum survivin levels in brain tumors of different grades and histologies. PMID- 30275229 TI - EGFR, SMAD7, and TGFBR2 Polymorphisms Are Associated with Colorectal Cancer in Patients with Lynch Syndrome. AB - BACKGROUND/AIM: Epidermal growth factor receptor (EGFR), mothers against decapentaplegic homolog 7 (SMAD7) and transforming growth factor betta (TGFB) are crucial for colorectal cancer (CRC) tumorigenesis. This study investigated whether polymorphisms in EGFR, SMAD7, and TGFB are associated with CRC risk in patients with Lynch syndrome. MATERIALS AND METHODS: Genotyping was performed using Sequenom iPLEX MassArray. Association between genetic polymorphisms and CRC was assessed using a weighted Cox proportional hazard model. RESULTS: Patients carrying the AA genotype of EGFR rs2227983 had a significantly higher CRC risk than those carrying the G allele (HR=2.55, 95% CI=1.25-5.17). The dominant model of SMAD7 rs12953717 (CT + TT genotypes) significantly increased CRC risk (HR=2.17, 95% CI=1.12-4.16) when compared to the wild-type CC genotype. Similarly, the GG genotype of TGFBR2 rs6785358 significantly increased the risk of CRC (HR=21.1, 95% CI=5.06-88.1) compared to the AA genotype. CONCLUSION: EGFR, SMAD7, and TGFBR2 are associated with CRC risk in patients with Lynch syndrome. PMID- 30275231 TI - Foamy Histiocyte-like Esophageal Adenocarcinoma: Unusual Morphology and Diagnostic Pitfalls. AB - In the United States and other western countries, the vast majority of primary esophageal malignancies are adenocarcinomas arising in the lower esophagus within a background of Barrett's esophagus. The microscopic feature of esophageal adenocarcinoma varies, with the tubular or papillary adenocarcinoma of intestinal pattern being the most common, and other less common morphological patterns include adenosquamous, signet ring cell, mucinous, mucoepidermoid, and adenoid cystic carcinoma. This is a case report of esophageal adenocarcinoma with foamy histiocyte-like feature in a 71-year-old male with a history of smoking and Barrett's esophagus who presented with dysphagia and weight loss. The tumor cells showed an abundant foamy cytoplasm, low N/C ratio and irregular nuclear contour. They were arranged in single, trabecular and glandular patterns and deeply invaded adventitia. Lymphovascular invasion and perineural invasion were present. The foamy histiocyte like-tumor cells were negative for CD68, but strongly and diffusely positive for CK7. E-Cadherin was maintained in the tumor cells, and p53 immunostaining revealed a wild-type staining pattern. To the best of our knowledge, this is the first documented case of primary esophageal adenocarcinoma with foamy-histiocyte-like phenotype. The clinical course, diagnosis and prognosis of this entity are discussed. PMID- 30275232 TI - Prominent Nucleoli and Non-glandular Feature Are Independent Predictors of PD-L1 Expression in Lung Adenocarcinoma. AB - BACKGROUND/AIM: In patients with non-small cell lung cancer, relationships between PD-L1 (programmed death-ligand 1) expression and clinicopathological characteristics have been examined. However, the association between cytological features and PD-L1 expression remains unknown. Thus, the aim of this study was to investigate whether nuclear features might be correlated with PD-L1 expression in patients with advanced and inoperable lung adenocarcinoma using small biopsy specimens. MATERIALS AND METHODS: Archived slides from 90 patients with lung adenocarcinoma who underwent small biopsy between October 2014 and May 2017 at the Incheon St. Mary's Hospital, were reviewed. PD-L1 expression was detected by immunohistochemistry using PD-L1 22C3 IHC assay. Associations of PD-L1 expression with pathological and molecular features (EGFR mutation, ALK and ROS-1 rearrangement) were statistically analyzed. RESULTS: PD-L1 expression in tumor cells was positive in 33 of 90 cases (36.7%). Higher PD-L1 expression (>=50%) was more frequent in cases with marked nuclear pleomorphism (p<0.001), coarse chromatin pattern (p=0.006), predominant nucleoli (>=3 MUm) (p<0.001), large nuclear diameter (>5* small lymphocyte) (p=0.006), non-glandular feature (p<0.001), and atypical mitosis (p=0.034). There were no significant correlations between PD-L1 positivity and molecular features. In multivariable logistic regression analysis, PD-L1 positivity was independently associated with prominent nucleoli (p=0.005) and non-glandular feature (p=0.007). CONCLUSION: Prominent nucleoli and non-glandular feature are independent predictors of PD-L1 expression in lung adenocarcinoma. PMID- 30275233 TI - Impact of CMV and EBV on Immune Recovery After Allogeneic Hematopoietic Cell Transplantation in Children. AB - BACKGROUND/AIM: Immune recovery is a key factor in the management of patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT). This study analyzed the factors contributing to immune reconstitution after allo-HSCT. PATIENTS AND METHODS: Overall, 65 children with malignant or non-malignant diseases were included in multivariate analyses. RESULTS: The following factors contributed to a faster immune recovery: peripheral blood as a stem cell source and reactivation of CMV infection for CD3+ and CD4+ lymphocyte subpopulations; reactivation of CMV infection for CD8+ subset; donor EBV-IgG+ and no EBV reactivation for CD19 lymphocytes; recipient age below 10 years and peripheral blood as a stem cell source for NK cells. For CD2 and CD4/CD8 ratio no factor was significant in multivariate analysis. CONCLUSION: Patients receiving a graft from an EBV-IgG-positive donor and not having early EBV post-transplant viremia show faster recovery of the B-cells, while patients with early CMV-DNA-emia have a better re-establishment of T-cell subsets. PMID- 30275234 TI - A Phase I/II Study of NAC with Docetaxel, Cisplatin, and S-1 for Stage III Gastric Cancer. AB - BACKGROUND/AIM: The aim of this phase I/II study was to determine the safety, and efficacy of combination of neoadjuvant chemotherapy (NAC) with biweekly docetaxel, cisplatin, and S-1 (DCS) in stage III gastric cancer patients. PATIENTS AND METHODS: In the phase I study, S1 was administered at doses of 80 mg/day to 120 mg/day depending on the body surface area and docetaxel was administered at 20 mg/m2, whereas cisplatin was initially administered at 25 mg/m2 and was escalated by 5 mg/m2 up to 50 mg/m2 In the phase II study, safety and therapeutic efficacy of DCS were evaluated using the recommended dose of cisplatin. RESULTS: In phase I, 21 patients were enrolled. In level II, perforation of gastric cancer occurred in one case although no dose limiting toxicities (DLTs) were noted in level III-VI. Recommended dose for cisplatin was 50 mg/m2/day. In phase II, among 47 patients, 14 experienced grade 3/4 adverse events. Clinically, response rate was 66.7% and disease control rate was 97.9%. The curative (R0) resection rate was 95.7%. Pathological response rate was 53.3%. Three-year overall survival and relapse-free survival rates were 78.5% and 65.3%, respectively. CONCLUSION: Biweekly DCS as NAC was efficient, safe, and acceptable; however, long-term survival should be evaluated to confirm the efficacy of biweekly DCS for stage III gastric cancer patients.

PMID- 30275235 TI - Profile and Outcome of Supraclavicular Metastases in Patients with Metastatic Breast Cancer: Discordance of Receptor Status Between Primary and Metastatic Site. AB - BACKGROUND: Breast cancer is a heterogenous and complex disease. A rare site of metastatic breast cancer disease is the neck. Data about supraclavicular metastases in patients with metastatic breast cancer are still lacking. Hence, our study aimed to analyze histological subtypes of supraclavicular metastases compared to the primary site. MATERIALS AND METHODS: This was a retrospective hospital-based cohort study of patients with breast cancer who developed supraclavicular metastases. Diagnosis of supraclavicular metastases was confirmed by biopsy or diagnostic lymph node extirpation. Histological subtypes were analyzed and Kaplan-Meier estimates were calculated for overall survival. RESULTS: A total of 20 patients were included in the analysis. The majority of the patients (12/20) had hormone receptor (HR)-positive/human epidermal growth factor receptor 2 (HER2)-negative supraclavicular metastases, disease in 3/20 patients was HR-positive/HER2-positive, HR-negative/HER2-positive in 1/20 patients and basal-like in 4/20 patients. Total discordance rates for estrogen receptor, progesterone receptor and HER2 between primary and metastatic tumors were 20.0%, 36.8% and 29.4%, respectively. The 5-year overall survival was 80%, whereas the 5-year survival after the onset of neck metastasis was 45%. CONCLUSION: As a rare site of metastatic breast cancer, supraclavicular metastases are associated with a worse median overall survival from their onset. The high rate of discordance of histological subtype stresses the necessity for biopsies in patients with supraclavicular metastasis. PMID- 30275237 TI - A Tool to Identify Adolescents at Risk of Cigarette Smoking Initiation. AB - : : media-1vid110.1542/5828318368001PEDS-VA_2017-3701Video Abstract OBJECTIVES: To describe the development of a prognostic tool to identify adolescents at risk for transitioning from never to ever smoking in the next year. METHODS: Data were drawn from the Nicotine Dependence in Teens study, a longitudinal investigation of adolescents (1999 to present). A total of 1294 students initially age 12 to 13 years were recruited from seventh-grade classes in 10 high schools in Montreal. Self-report questionnaire data were collected every 3 months during the 10-month school year over 5 years (1999-2005) until participants completed high school (n = 20 cycles). Prognostic variables for inclusion in the multivariable analyses were selected from 58 candidate predictors describing sociodemographic characteristics, smoking habits of family and friends, lifestyle factors, personality traits, and mental health. Cigarette smoking initiation was defined as taking even 1 puff on a cigarette for the first time, as measured in a 3-month recall of cigarette use completed in each cycle. RESULTS: The cumulative incidence of cigarette smoking initiation was 16.3%. Data were partitioned into a training set for model-building and a testing set to evaluate the performance of the model. The final model included 12 variables (age, 4 worry or stress-related items, 1 depression-related item, 2 self-esteem items, and 4 alcohol- or tobacco related variables). The model yielded a c-statistic of 0.77 and had good calibration. CONCLUSIONS: This short prognostic tool, which can be incorporated into busy clinical practice, was used to accurately identify adolescents at risk for cigarette smoking initiation.

PMID- 30275240 TI - Revisiting the role of metabolism during development. AB - An emerging view emphasizes that metabolism is highly regulated in both time and space. In addition, it is increasingly being recognized that metabolic pathways are tightly connected to specific biological processes such as cell signaling, proliferation and differentiation. As we obtain a better view of this spatiotemporal regulation of metabolism, and of the molecular mechanisms that connect metabolism and signaling, we can now move from largely correlative to more functional studies. It is, therefore, a particularly promising time to revisit how metabolism can affect multiple aspects of animal development. In this Review, we discuss how metabolism is mechanistically linked to cellular and developmental programs through both its bioenergetic and metabolic signaling functions. We highlight how metabolism is regulated across various spatial and temporal scales, and discuss how this regulation can influence cellular processes such as cell signaling, gene expression, and epigenetic and post-translational modifications during embryonic development. PMID- 30275241 TI - RON Receptor Tyrosine Kinase as a Therapeutic Target for Eradication of Triple Negative Breast Cancer: Efficacy of Anti-RON ADC Zt/g4-MMAE. AB - Triple-negative breast cancer (TNBC) is a highly diverse group of malignant neoplasia with poor outcome. Currently, the lack of effective therapy has fostered a major effort to discover new targets to treat this malignant cancer. Here we identified the RON receptor tyrosine kinase as a therapeutic target for potential TNBC treatment. We analyzed RON expression in 168 primary TNBC samples via tissue microarray using anti-RON IHC staining and demonstrated that RON was widely expressed in 76.8% TNBC samples with overexpression in 76 cases (45.2%). These results provide the molecular basis to target RON for TNBC therapy. To this end, anti-RON monoclonal antibody Zt/g4-drug monomethyl auristatin E conjugate (Zt/g4-MMAE) was developed with a drug to antibody ratio of 3.29 and tested in a panel of TNBC cell lines with different phenotypes. In vitro, Zt/g4-MMAE rapidly induced RON internalization, resulted in cell-cycle arrest followed by massive cell death. The calculated IC50 values ranged from 0.06 to 3.46 MUg/mL dependent on individual TNBC cell lines tested. Zt/g4-MMAE also effectively killed TNBC stem-like cells with RON+/CD44+/CD24- phenotypes and RON-negative TNBC cells through the bystander effect. In vivo, Zt/g4-MMAE at 10 mg/kg in a Q12 * 2 regimen completely eradicated TNBC xenografts without the regrowth of xenograft tumors. In conclusion, increased RON expression is a pathogenic feature in primary TNBC samples. Zt/g4-MMAE is highly effective in eradicating TNBC xenografts in preclinical models. These findings lay the foundation for using anti-RON Zt/g4-MMAE in clinical trials as a novel strategy for TNBC treatment. PMID- 30275244 TI - An Introduction to the Duchenne Muscular Dystrophy Care Considerations. PMID- 30275242 TI - Tumor Sidedness and Enriched Gene Groups for Efficacy of First-line Cetuximab Treatment in Metastatic Colorectal Cancer. AB - Molecular differences in tumor locations may contribute to the sidedness-specific response to cetuximab in metastatic colorectal cancer (mCRC). We investigated genes associated with the response to cetuximab treatment depending on tumor sidedness. Our study included 77 patients with mCRC (13/63, right/left) with KRAS exon 2 wild-type tumors from phase II trials of first-line therapy with cetuximab. Expression levels of 2,551 genes were measured in tissue samples by HTG EdgeSeq Oncology Biomarker Panel. Univariate Cox regression analysis using log2 values of counts per million (CPM) was conducted in each sidedness to assess associations with clinical outcomes, and to define the optimal cut-off point for clinically significant genes. In addition, a gene set enrichment analysis (GSEA) was performed to identify significant gene pathways in each sidedness. Sixty-nine patients were assessable for gene expression data. Overexpression of BECN1 [log2(CPM) >= 6.8] was associated with favorable survival, regardless of tumor sidedness. High expression of NOTCH1 [log2(CPM) >= 7.5] predicted significantly longer progression-free survival (PFS; median 14.7 vs. 11.1 months, HR 0.43, P = 0.01) and overall survival (OS; median 42.8 vs. 26.5 months, HR 0.35, P = 0.01) in left side but not in right side. The GSEA showed that regulation of DNA replication gene set correlated with favorable survival in the left, whereas the subcellular component and leukocyte migration gene sets were associated with good survival in the right. In conclusion, genes contributing to the efficacy of cetuximab treatment may differ according to the sidedness in mCRC. NOTCH1 may potentially discriminate favorable responders to cetuximab in patients with left sided tumors. PMID- 30275245 TI - Neurology Care, Diagnostics, and Emerging Therapies of the Patient With Duchenne Muscular Dystrophy. AB - Duchenne muscular dystrophy is the most common form of childhood muscular dystrophy. A mutation in the DMD gene disrupts dystrophin (protein) production, causing damage to muscle integrity, weakness, loss of ambulation, and cardiopulmonary compromise by the second decade of life. Life expectancy has improved from mid-teenage years to mid-20s with the use of glucocorticoids and beyond the third decade with ventilator support and multidisciplinary care. However, Duchenne muscular dystrophy is associated with comorbidities and is a fatal disease. Glucocorticoids prolong ambulation, but their side effects are significant. Emerging investigational therapies have surfaced over the past decade and have rapidly been tested in clinical trials. Gene-specific strategies include nonsense readthrough, exon skipping, gene editing, utrophin modulation, and gene replacement. Other mechanisms include muscle regeneration, antioxidants, and antifibrosis and anti-inflammatory pathways. With potential therapies emerging, early diagnosis is needed to initiate treatment early enough to minimize morbidity and mortality. Newborn screening can be used to significantly improve early diagnosis, especially for gene-specific therapeutics. PMID- 30275246 TI - Rehabilitation Management of the Patient With Duchenne Muscular Dystrophy. AB - Steadily improving management of Duchenne muscular dystrophy (DMD) continues to lead to improved physical and functional status, allowing increasingly successful transitions to independence and self-actualization in adulthood. Rehabilitation principles remain key to overall management for individuals with DMD with increasing options for ever more successful management, reflecting a changing natural history based on the use of glucocorticoids, more consistent comprehensive care, and the emergence of disease-modifying treatments. Advances and expansion in assessment, cardiorespiratory management, preventive management of contracture and deformity, assistive technology, "smart" technology, and robotics with increased emphasis on function, participation, self-advocacy, and independence in decision-making should allow individuals with DMD to experience childhood and transition to adulthood with support that allows for increasing success in the achievement of individual goals and fulfillment across the life span. PMID- 30275247 TI - Bone Health and Osteoporosis Management of the Patient With Duchenne Muscular Dystrophy. AB - Duchenne muscular dystrophy is associated with an increased risk of bone fragility due to the adverse effects of prolonged glucocorticoid therapy and progressive muscle weakness on bone strength. Osteoporosis manifests clinically as low-trauma long-bone and vertebral fractures (VFs), with VFs frequent, particularly in those treated with glucocorticoid therapy. It is increasingly recognized that bone pain, medical complications of osteoporosis (such as fat embolism syndrome), and the potential for permanent, fracture-induced loss of ambulation can be mitigated with timely bone health surveillance and management. This includes periodic spine radiographs for VF detection because VFs can be asymptomatic in their early phases and thereby go undetected in the absence of monitoring. With this article, we provide a comprehensive review of the following 4 phases of bone health management: (1) bone health monitoring, which is used to identify early signs of compromised bone health; (2) osteoporosis stabilization, which is aimed to mitigate back pain and interrupt the fracture-refracture cycle through bone-targeted therapy; (3) bone health maintenance, which has the goal to preserve the clinical gains realized during the stabilization phase through ongoing bone-targeted therapy; and (4) osteoporosis therapy discontinuation, which places those who are eligible for discontinuation of osteoporosis treatment back on a health monitoring program. In the course of reviewing these 4 phases of management, we will discuss the criteria for diagnosing osteoporosis, along with detailed recommendations for osteoporosis intervention including specific drugs, dose, length of therapy, contraindications, and monitoring of treatment efficacy and safety. PMID- 30275248 TI - Obesity and Endocrine Management of the Patient With Duchenne Muscular Dystrophy. AB - Duchenne muscular dystrophy (DMD) is associated with an increased risk of endocrine complications due to the effects of prolonged glucocorticoid therapy as well as progressive muscle weakness. Categories of complications include obesity and its comorbidities, short stature, pubertal delay, and adrenal insufficiency. Obesity prevention is important for long-term management of patients with DMD. Preventing glucocorticoid-induced weight gain fosters patient mobility, ease of transfer, and reduces sleep-disordered breathing. Metabolic complications from obesity (glucose intolerance, dyslipidemia) also can be avoided. Short stature and pubertal delay may negatively affect self-esteem and peer relationships, and careful monitoring of growth and pubertal development can allow anticipatory counseling. Adrenal insufficiency, a potentially life-threatening complication associated with prolonged glucocorticoid use, must be recognized so as to allow prompt treatment. In this article, we provide a summary of current guidance to ensure comprehensive endocrine management is followed in patients with DMD. PMID- 30275249 TI - Nutritional and Gastrointestinal Management of the Patient With Duchenne Muscular Dystrophy. AB - Advances in treatment and multidisciplinary management have resulted in improved survival of individuals with Duchenne muscular dystrophy (DMD). Updated DMD treatment recommendations as found in the 2018 DMD Care Considerations are aimed to assist multidisciplinary care teams in providing standardized care to their patients, including attention to nutritional and gastrointestinal health. Challenges remain for care teams in accurately estimating height and nutritional status for individuals with DMD. It can be difficult for patients to maintain a healthy weight. Risk factors for obesity include glucocorticoid therapy and loss of ambulation. In contrast, in the later stages of the disease, swallowing dysfunction can lead to poor nutrition and consideration for gastrostomy tube placement. Constipation is highly prevalent, underrecognized, and undertreated in DMD. With this article, we address the assessment and management of gastrointestinal and nutritional issues, as well as clinical controversies. PMID- 30275250 TI - Respiratory Management of the Patient With Duchenne Muscular Dystrophy. AB - In 2010, Care Considerations for Duchenne Muscular Dystrophy, sponsored by the Centers for Disease Control and Prevention, was published in Lancet Neurology, and in 2018, these guidelines were updated. Since the publication of the first set of guidelines, survival of individuals with Duchenne muscular dystrophy has increased. With contemporary medical management, survival often extends into the fourth decade of life and beyond. Effective transition of respiratory care from pediatric to adult medicine is vital to optimize patient safety, prognosis, and quality of life. With genetic and other emerging drug therapies in development, standardization of care is necessary to accurately assess treatment effects in clinical trials. This revision of respiratory recommendations preserves a fundamental strength of the original guidelines: namely, reliance on a limited number of respiratory tests to guide patient assessment and management. A progressive therapeutic strategy is presented that includes lung volume recruitment, assisted coughing, and assisted ventilation (initially nocturnally, with the subsequent addition of daytime ventilation for progressive respiratory failure). This revision also stresses the need for serial monitoring of respiratory muscle strength to characterize an individual's respiratory phenotype of severity as well as provide baseline assessments for clinical trials. Clinical controversies and emerging areas are included. PMID- 30275251 TI - Cardiac Management of the Patient With Duchenne Muscular Dystrophy. AB - Duchenne muscular dystrophy (DMD) results in a progressive cardiomyopathy that produces significant morbidity and mortality. To improve the quality of life in patients with DMD, cardiac care is focused on surveillance and management, with the goal of slowing the onset and progression of heart failure complications. The current article is intended to be an expanded review on the cardiac management data used to inform the 2018 DMD Care Considerations recommendations as well as be a discussion on clinical controversies and future management directions. The new cardiac guidance includes changes regarding noninvasive imaging surveillance of cardiac function and pharmacologic therapy. Many emerging therapies lack sufficient evidence-based data to be recommended in the 2018 DMD Care Considerations. These are discussed in the present article as clinical controversies and future directions. Important emerging therapies include new heart failure medications, mechanical circulatory support with ventricular assist devices, heart transplantation, and internal cardiac defibrillators. Future research studies should be focused on the risks and benefits of these advanced therapies in patients with DMD. We conclude this review with a brief discussion on the relationship between the heart and the recently developed medications that are used to directly target the absence of dystrophin in DMD. PMID- 30275252 TI - Orthopedic and Surgical Management of the Patient With Duchenne Muscular Dystrophy. AB - Orthopedic care is an important aspect of the overall management of patients with Duchenne muscular dystrophy (DMD). In addition to progressive muscle weakness and loss of function, patients may develop joint contractures, scoliosis, and osteoporosis, causing fractures; all of these necessitate intervention by a multidisciplinary team including an orthopedic surgeon as well as rehabilitation specialists such as physio- and occupational therapists. The causes of these musculoskeletal complications are multifactorial and are related to primary effects on the muscles from the disease itself, secondary effects from weak muscles, and the related side effects of treatments, such as glucocorticoid use that affect bone strength. The musculoskeletal manifestations of DMD change over time as the disease progresses, and therefore, musculoskeletal management needs change throughout the life span of an individual with DMD. In this review, we target pediatricians, neurologists, orthopedic surgeons, rehabilitation physicians, anesthesiologists, and other individuals involved in the management of patients with DMD by providing specific recommendations to guide clinical practice related to orthopedic issues and surgical management in this setting. PMID- 30275253 TI - Primary Care and Emergency Department Management of the Patient With Duchenne Muscular Dystrophy. AB - Primary care providers (PCPs) are usually the first point of contact with the health care system for patients with Duchenne muscular dystrophy (DMD), and patients often present to emergency departments in which providers have little experience in dealing with this condition. With this article, we give primary care and emergency medicine providers a background in the common issues that affect people with DMD. By acquiring some specialized knowledge about the multisystem medical complications of DMD and by applying general principles of primary care, such as timely immunization, anticipatory safety counseling, behavioral screening, and routine nutritional and developmental assessments, the PCP can be a valued and effective medical provider to patients with DMD. The PCP can provide access to and effective coordination among the patient's specialty caregivers. Moreover, the PCP can become a trusted advisor to the patient and his family about important medical decisions, as well as issues in the psychosocial, behavioral, and educational domains. This article also contains a "pocket guide" used to assess and manage common urgent medical problems that cause patients with DMD to seek care in the emergency department. With the background information discussed in this article, both PCPs and emergency medicine physicians can skillfully care for patients with DMD in their respective settings, optimizing patient outcomes. PMID- 30275254 TI - Psychosocial Management of the Patient With Duchenne Muscular Dystrophy. AB - In this article, we outline a comprehensive plan for the psychosocial management of patients with Duchenne muscular dystrophy (DMD) across the life span. In 2010, the Centers for Disease Control and Prevention sponsored the development of multidisciplinary management guidance for DMD, and in 2018, that guidance was updated. In the intervening years, a new emphasis was placed on studying and addressing the psychosocial issues that affect patients with DMD, driven in part by improved patient survival. Once viewed as ancillary to managing the significant medical needs of patients with DMD, it is now standard practice to integrate psychosocial management into the multidisciplinary management of the disease. It is also increasingly recognized that neurodevelopmental disorders in DMD occur at a higher rate than what was previously understood and that these disorders warrant early and intensive intervention. In this article, we expand on the content found in the 2018 DMD Care Considerations. PMID- 30275255 TI - A Transition Toolkit for Duchenne Muscular Dystrophy. AB - The care of individuals with Duchenne muscular dystrophy (DMD) now extends into adulthood. Childhood to adulthood transition planning is an important aspect of care, affecting health outcomes as well as other important aspects of adult life. In this article, we address transition planning as it relates to DMD health care, education, steps toward vocations, personal care, accessing the home and community, and the importance of relationships with others. Because of the complex, disabling, and progressive nature of DMD, coordinated, well-timed planning is critical to ensure that all components of transition are accomplished. In this article, we introduce the DMD Transition Toolkit. The toolkit is designed to help assess readiness for transition, track progress toward transition goals, and provide a template for documenting key elements of medical care, medical equipment, and services. The transition readiness assessment for young adults with DMD is used to gauge readiness for adult health care and living practices. Consistent with the 2018 DMD Care Considerations, the transition checklist for young adults with DMD is a comprehensive list to be considered, discussed, and planned for during transition. The medical summary for young adults with DMD can be used by a provider or individuals with DMD to communicate details of their health plan, provider contacts, and medical equipment needs. It can be used in transition handoffs, when adding new providers, or when informing new nursing agencies or personal care attendants. It could also be useful in urgent care settings by providing baseline information about the individual with DMD. PMID- 30275256 TI - Evaluating Implementation of the Updated Care Considerations for Duchenne Muscular Dystrophy. AB - Care Considerations for Duchenne Muscular Dystrophy were published in 2010. However, little is known about the extent to which these considerations were implemented after publication. With this article, we provide direction on evaluating the uptake of the 2018 Duchenne Muscular Dystrophy Care Considerations. We identify key elements of care and present suggestions for their use in evaluation and research. PMID- 30275257 TI - Hydroxychloroquine Levels throughout Pregnancies Complicated by Rheumatic Disease: Implications for Maternal and Neonatal Outcomes. AB - OBJECTIVE: Pregnancies in women with active rheumatic disease often result in poor neonatal outcomes. Hydroxychloroquine (HCQ) reduces disease activity and flares; however, pregnancy causes significant physiologic changes that may alter HCQ levels and lead to therapeutic failure. Therefore, our objective was to evaluate HCQ concentrations during pregnancy and relate levels to outcomes. METHODS: We performed an observational study of pregnant patients with rheumatic disease who were taking HCQ from a single center during 2013-2016. Serum samples were analyzed using high-performance liquid chromatography/mass spectrometry. Primary HCQ exposure was categorized as nontherapeutic (<= 100 ng/ml) or therapeutic (> 100 ng/ml). Categorical outcomes were analyzed using Fisher's exact test and continuous outcomes using linear regression models, Wilcoxon signed-rank test, Kruskal-Wallis test, t test, and ANOVA. RESULTS: We analyzed 145 samples from 50 patients with rheumatic disease, 56% of whom had systemic lupus erythematosus (SLE). HCQ concentration varied widely among individuals at each trimester. Mean physician's global assessment scores in patients with SLE were significantly higher in those with average drug levels <= 100 ng/ml compared to > 100 ng/ml (0.93 vs 0.32, p = 0.01). Of patients with SLE, 83% with average drug levels <= 100 ng/ml delivered prematurely (n = 6), compared to only 21% with average levels > 100 ng/ml (n = 19; p = 0.01). HCQ levels were not associated with prematurity or disease activity in non-SLE patients. CONCLUSION: With both high and low HCQ levels associated with preterm birth and disease activity in SLE, further study is necessary to understand HCQ disposition throughout pregnancy and to clarify the relationship between drug levels and outcomes. PMID- 30275258 TI - Performance of the Expanded Cardiovascular Risk Prediction Score for Rheumatoid Arthritis Is Not Superior to the ACC/AHA Risk Calculator. AB - OBJECTIVE: Cardiovascular (CV) risk estimation calculators for the general population do not perform well in patients with rheumatoid arthritis (RA). An RA specific risk calculator has been developed, but did not perform better than a risk calculator for the general population when validated in a heterogeneous multinational cohort. METHODS: In a cohort of patients with new-onset RA from northern Sweden (n = 665), the risk of CV disease was estimated by the Expanded Cardiovascular Risk Prediction Score for Rheumatoid Arthritis (ERS-RA) and the American College of Cardiology/American Heart Association algorithm (ACC/AHA). The ACC/AHA estimation was analyzed, both as crude data and when adjusted according to the recommendations by the European League Against Rheumatism (ACC/AHA * 1.5). ERS-RA was calculated using 2 variants: 1 from patient and physician reports of hypertension (HTN) and hyperlipidemia [ERS-RA (reported)] and 1 from assessments of blood pressure (BP) and blood lipids [ERS-RA (measured)]. The estimations were compared with observed CV events. RESULTS: All variants of risk calculators underestimated the CV risk. Discrimination was good for all risk calculators studied. Performance of all risk calculators was poorer in patients with a high grade of inflammation, whereas ACC/AHA * 1.5 performed best in the high-inflammatory patients. In those patients with an estimated risk of 5-15%, no risk calculator performed well. CONCLUSION: ERS-RA underestimated the risk of a CV event in our cohort of patients, especially when risk estimations were based on patient or physician reports of HTN and hyperlipidemia instead of assessment of BP and blood lipids. The performance of ERS-RA was no better than that of ACC/AHA * 1.5, and neither performed well in high inflammatory patients. PMID- 30275259 TI - Toward New Classification Criteria for Juvenile Idiopathic Arthritis: First Steps, Pediatric Rheumatology International Trials Organization International Consensus. AB - OBJECTIVE: To revise the current juvenile idiopathic arthritis (JIA) International League of Associations for Rheumatology (ILAR) classification criteria with an evidence-based approach, using clinical and routine laboratory measures available worldwide, to identify homogeneous clinical groups and to distinguish those forms of chronic arthritis typically seen only in children from the childhood counterpart of adult diseases. METHODS: The overall project consists of 4 steps. This work represents Step 1, a Delphi Web-based consensus and Step 2, an international nominal group technique (NGT) consensus conference for the new provisional Pediatric Rheumatology International Trials Organization JIA classification criteria. A future large data collection of at least 1000 new onset JIA patients (Step 3) followed by analysis and NGT consensus (Step 4) will provide data for the evidence-based validation of the JIA classification criteria. RESULTS: In Step 1, three Delphi rounds of interactions were implemented to revise the 7 ILAR JIA categories. In Step 2, forty-seven questions with electronic voting were implemented to derive the new proposed criteria. Four disorders were proposed: (a) systemic JIA; (b) rheumatoid factor-positive JIA; (c) enthesitis/spondylitis-related JIA; and (d) early-onset antinuclear antibody positive JIA. The other forms were gathered under the term "others." These will be analyzed during the prospective data collection using a list of descriptors to see whether the clustering of some of them could identify homogeneous entities. CONCLUSION: An international consensus was reached to identify different proposed homogeneous chronic disorders that fall under the historical term JIA. These preliminary criteria will be formally validated with a dedicated project. PMID- 30275261 TI - Relationship Between Insulin Sensitivity and beta-Cell Secretion in Nondiabetic Subjects with Rheumatoid Arthritis. AB - OBJECTIVE: In nondiabetic healthy individuals, insulin secretion and sensitivity are linked by a negative feedback loop characterized by a hyperbolic function. We aimed to study the association of traditional insulin resistance (IR) factors with insulin secretion and sensitivity, and to determine whether the hyperbolic equilibrium of this relation is preserved in patients with rheumatoid arthritis (RA). METHODS: This was a cross-sectional study encompassing 361 nondiabetic individuals: 151 with RA and 210 controls. Insulin, C-peptide, and IR indices by homeostatic model (HOMA2) were assessed. A multivariable analysis was performed to evaluate the differences in the correlation of traditional IR-related factors with glucose homeostasis molecules, as well as IR indices between patients and controls. Nonlinear regression analysis was used to assess the hyperbolic relation of insulin sensitivity and secretion. RESULTS: HOMA2-IR indices were higher in patients with RA than controls. Hepatic insulin extraction, as assessed by the insulin:C-peptide molar ratio, was lower in patients with RA after multivariable analysis (0.08 +/- 0.02 vs 0.14 +/- 0.07, p < 0.001). Traditional IR-related factors showed significantly lower adjusted correlation coefficients with IR indices in patients with RA. The association between insulin sensitivity and secretion showed a different hyperbolic relation in patients with RA: the variability explained by the curve was lower in RA (nonlinear r2 = 0.845 vs r2 = 0.928, p = 0.001) and beta coefficients (-0.74, 95% CI -0.77 to -0.70 vs -1.09, 95% CI -1.17 to -1.02, ng/ml, p < 0.001) were different in RA. CONCLUSION: The traditional factors associated with IR in healthy individuals are less related to IR in patients with RA. Insulin sensitivity and secretion yield a different hyperbolic equilibrium in RA.

AB - OBJECTIVE: Biologic therapies can improve disease control for patients with rheumatoid arthritis (RA) but may be both overused and underused. We aimed to identify predictors of greater use of biologic therapies and to identify factors associated with persistent glucocorticoid use. METHODS: Using national US Veteran's Affairs databases 2005-2016, we identified patients with RA receiving a first-ever prescription of methotrexate (MTX), requiring >= 6 months of baseline data. We evaluated predictors of biologic therapy initiation within 2 years of starting MTX and factors associated with baseline and persistent glucocorticoid use at 6-12 months using multivariable models. RESULTS: Among 17,415 patients starting MTX, 3263 patients received biologic therapy within 2 years (20.6% 2-yr incidence). In adjusted analyses, biologic use was substantially lower in older patients [e.g., aHR 0.20 (95% CI 0.16, 0.26) for patients >= 80 vs < 50] and patients with more comorbidities [aHR 0.79 (95% CI 0.72, 0.87) for Charlson score >= 3 vs < 3]. Patients with heart failure [aHR 0.68 (95% CI 0.54, 0.84)], cancer [aHR 0.78 (95% CI 0.66, 0.92)], or who were nonwhite [aHR 0.79 (95% CI 0.72, 0.87)] were also less likely to receive a biologic. In contrast, baseline and persistent glucocorticoid use was similar across age groups and more common in patients with greater comorbidity. CONCLUSION: Biologic therapy is initiated less frequently in patients with RA who are older, have more comorbidities, and who are nonwhite. While biologics may be avoided in older and sicker patients because of safety concerns, glucocorticoid use is similar regardless of age and is more frequent in patients with comorbidities, with implications for patient outcomes. PMID- 30275260 TI - Risk Factors for Mortality and Cardiopulmonary Hospitalization in Systemic Sclerosis Patients At Risk for Pulmonary Hypertension, in the PHAROS Registry. AB - OBJECTIVE: We sought to identify predictors of mortality and cardiopulmonary hospitalizations in patients at risk for pulmonary hypertension (PH) and enrolled in PHAROS, a prospective cohort study to investigate the natural history of PH in systemic sclerosis (SSc). METHODS: The at-risk population for PH was defined by the following entry criteria: echocardiogram systolic pulmonary arterial pressure > 40 mmHg, or DLCO < 55% predicted or ratio of % forced vital capacity/%DLCO > 1.6, measured by pulmonary function testing. Baseline clinical measures were evaluated as predictors of hospitalization and death between 2005 and 2014. Cox proportional hazards models were censored at date of PH onset or latest study visit and adjusted for age, sex, race, and disease duration. RESULTS: Of the 236 at-risk subjects who were followed for a median of 4 years (range 0.4-8.5 yrs), 35 developed PH after entering PHAROS (reclassified as PH group). In the at-risk group, higher mortality was strongly associated with male sex, low %DLCO, exercise oxygen desaturation, anemia, abnormal dyspnea scores, and baseline pericardial effusion. Risks for cardiopulmonary hospitalization were associated with increased dyspnea and pericardial effusions, although PH patients with DLCO < 50% had the highest risk of cardiopulmonary hospitalizations. CONCLUSION: Risk factors for poor outcome in patients with SSc who are at risk for PH were similar to others with SSc-PH and SSc-pulmonary arterial hypertension, including male sex, DLCO < 50%, exercise oxygen desaturation, and pericardial effusions. This group should undergo right heart catheterization and receive appropriate intervention if PH is confirmed. PMID- 30275263 TI - Quadriceps Weakness and the Risk of Knee Cartilage Loss Seen on Magnetic Resonance Imaging in a Population-based Cohort with Knee Pain. AB - OBJECTIVE: To determine whether baseline quadriceps weakness predicts cartilage loss assessed on magnetic resonance imaging (MRI). METHODS: Subjects aged 40-79 with knee pain (n = 163) were recruited from a random population sample and examined for quadriceps weakness with manual isometric strength testing, using a 3-point scoring system (0 = poor resistance, 1 = moderate resistance, 2 = full resistance), which was dichotomized as normal (grade 2) versus weak (grade 0/1). MRI of the more symptomatic knee was obtained at baseline and at mean of 3.3 years. Cartilage was graded 0-4 on MRI. Exponential regression analysis was used to evaluate whether quadriceps weakness was associated with whole knee cartilage loss, and in secondary analyses with compartment-specific cartilage loss, adjusted for age, sex, body mass index, Western Ontario and McMaster Universities Osteoarthritis Arthritis Index pain score, and baseline MRI cartilage score. RESULTS: Of 163 subjects, 54% were female, with a mean age of 57.7 years. Quadriceps weakness was seen in 11.9% of the subjects. Weakness was a predictor of whole knee cartilage loss (HR 3.48, 95% CI 1.30-9.35). Quadriceps weakness was associated with cartilage loss in the medial tibiofemoral (TF) compartment (HR 4.60, 95% CI 1.25-17.02), while no significant association was found with lateral TF (HR 1.53, 95% CI 0.24-9.78) or patellofemoral compartment (HR 2.76, 95% CI 0.46-16.44). CONCLUSION: In this symptomatic, population-based cohort, quadriceps weakness predicted whole knee and medial TF cartilage loss after 3 years. To our knowledge, this is the first study to show that a simple clinical examination of quadriceps strength can predict the risk of knee cartilage loss. PMID- 30275264 TI - Longterm Data on Sirolimus Treatment in Patients with Lupus Nephritis. AB - OBJECTIVE: To expand the limited longterm data on sirolimus treatment in patients with lupus nephritis (LN). Our pilot short-term data suggested efficacy of sirolimus treatment in these patients. METHODS: We retrospectively reviewed 16 class III/IV/V patients with LN who have received prednisolone (PSL) and sirolimus either as initial or maintenance treatment. RESULTS: Sixteen patients received sirolimus treatment (9 because of intolerance to standard immunosuppressants and 7 because of a history of malignancy) for 45.3 +/- 36.5 months. In 5 patients, sirolimus and PSL were given as induction for active nephritis, and they showed improvements in proteinuria (2.8 +/- 1.9 g/day at baseline, 0.1 +/- 0.1 g/day after 36 mos, p = 0.011), anti-dsDNA (107.7 +/- 91.9 IU/ml and 37.0 +/- 55.4 IU/ml, respectively, p = 0.178), and C3 (54.8 +/- 26.1 mg/dl and 86.3 +/- 18.6 mg/dl, respectively, p = 0.081). Eleven patients received sirolimus and low-dose PSL as longterm maintenance, and they showed continued improvement in C3 (90.4 +/- 18.1 mg/dl and 117.7 +/- 25.1 mg/dl at commencement and after 36 mos, respectively, p = 0.025), stable renal function (estimated glomerular filtration rate 58.6 +/- 25.8 ml/min and 63.0 +/- 29.6 ml/min, respectively, p = 0.239), and proteinuria (0.8 +/- 0.7 g/day and 0.7 +/- 0.7 g/day respectively, p = 0.252). Renal flare occurred in 1 patient, and another patient who had stage 4 chronic kidney disease when sirolimus was started developed endstage renal failure after 27 months. Sirolimus was discontinued in 5 patients, in 4 cases related to drug side effects. Deterioration of dyslipidemia occurred in 4 patients, but was adequately controlled with statin therapy. CONCLUSION: The preliminary evidence suggests that sirolimus may serve as an alternative treatment for patients with LN who do not tolerate standard treatment or who had a history of malignancy, and it has an acceptable longterm safety profile. PMID- 30275265 TI - Performance of Forced Vital Capacity and Lung Diffusion Cutpoints for Associated Radiographic Interstitial Lung Disease in Systemic Sclerosis. AB - OBJECTIVE: Forced vital capacity (FVC) and DLCO are used for screening of systemic sclerosis-associated interstitial lung disease (SSc-ILD). The study purpose was to determine the sensitivity, specificity, and negative predictive value (NPV) (proportion of true negative screening tests) of FVC and DLCO thresholds for SSc-ILD on chest high-resolution computed tomography (HRCT) scans. METHODS: Patients fulfilling American College of Rheumatology 2013 SSc criteria with a chest HRCT scan and pulmonary function tests (PFT) were studied. A thoracic radiologist quantified radiographic ILD. Optimal FVC and DLCO % predicted thresholds for ILD were identified using receiver-operating characteristic curves. The FVC and DLCO combinations with greatest sensitivity and specificity were also determined. Subanalysis was performed in patients with positive Scl-70 autoantibodies. RESULTS: The study included 265 patients. Of 188 (71%) with radiographic ILD, 59 (31%) had "normal" FVC (>= 80% predicted), and 65 out of 151 (43%) had "normal" DLCO (>= 60% predicted). FVC < 80% (sensitivity 0.69, specificity 0.73), and DLCO < 62% (sensitivity 0.60, specificity 0.70) were optimal thresholds for radiographic SSc-ILD. All FVC and DLCO threshold combinations evaluated had NPV < 0.70. The NPV for radiographic ILD for FVC < 80% was lower in patients with positive Scl-70 autoantibody (NPV = 0.05) compared to negative Scl-70 autoantibody (NPV = 0.57). CONCLUSION: Radiographic ILD is prevalent in SSc despite "normal" PFT. No % predicted FVC or DLCO threshold combinations yielded high NPV for SSc-ILD screening. "Normal" FVC and DLCO in patients with SSc, especially those with positive Scl-70 autoantibodies, should not obviate consideration of HRCT for ILD evaluation.

PMID- 30275266 TI - Esrrb extinction triggers dismantling of naive pluripotency and marks commitment to differentiation. AB - Self-renewal of embryonic stem cells (ESCs) cultured in LIF/fetal calf serum (FCS) is incomplete with some cells initiating differentiation. While this is reflected in heterogeneous expression of naive pluripotency transcription factors (TFs), the link between TF heterogeneity and differentiation is not fully understood. Here, we purify ESCs with distinct TF expression levels from LIF/FCS cultures to uncover early events during commitment from naive pluripotency. ESCs carrying fluorescent Nanog and Esrrb reporters show Esrrb downregulation only in Nanoglow cells. Independent Esrrb reporter lines demonstrate that Esrrbnegative ESCs cannot effectively self-renew. Upon Esrrb loss, pre-implantation pluripotency gene expression collapses. ChIP-Seq identifies different regulatory element classes that bind both OCT4 and NANOG in Esrrbpositive cells. Class I elements lose NANOG and OCT4 binding in Esrrbnegative ESCs and associate with genes expressed preferentially in naive ESCs. In contrast, Class II elements retain OCT4 but not NANOG binding in ESRRB-negative cells and associate with more broadly expressed genes. Therefore, mechanistic differences in TF function act cumulatively to restrict potency during exit from naive pluripotency.

PMID- 30275269 TI - Nonsense-mediated mRNA decay involves two distinct Upf1-bound complexes. AB - Nonsense-mediated mRNA decay (NMD) is a translation-dependent RNA degradation pathway involved in many cellular pathways and crucial for telomere maintenance and embryo development. Core NMD factors Upf1, Upf2 and Upf3 are conserved from yeast to mammals, but a universal NMD model is lacking. We used affinity purification coupled with mass spectrometry and an improved data analysis protocol to characterize the composition and dynamics of yeast NMD complexes in yeast (112 experiments). Unexpectedly, we identified two distinct complexes associated with Upf1: Upf1-23 (Upf1, Upf2, Upf3) and Upf1-decapping Upf1 decapping contained the mRNA decapping enzyme, together with Nmd4 and Ebs1, two proteins that globally affected NMD and were critical for RNA degradation mediated by the Upf1 C-terminal helicase region. The fact that Nmd4 association with RNA was partially dependent on Upf1-23 components and the similarity between Nmd4/Ebs1 and mammalian Smg5-7 proteins suggest that NMD operates through conserved, successive Upf1-23 and Upf1-decapping complexes. This model can be extended to accommodate steps that are missing in yeast, to serve for further mechanistic studies of NMD in eukaryotes.

PMID- 30275275 TI - Technique Development for Probing RNA Structure In Vivo and Genome-Wide. AB - SUMMARYHow organisms perceive and respond to their surroundings is one of the great questions in biology. It is clear that RNA plays key roles in sensing. Cellular and environmental cues that RNA responds to include temperature, ions, metabolites, and biopolymers. Recent advances in next-generation sequencing and in vivo chemical probing have provided unprecedented insights into RNA folding in vivo and genome-wide. Patterns of chemical reactivity have implicated control of gene expression by RNA and aided prediction of RNA structure. Central to these advances has been development of molecular biological and chemical techniques. Key advances are improvements in the quality, cost, and throughput of library preparation; availability of a wider array of chemicals for probing RNA structure in vivo; and robustness and user friendliness of data analysis. Insights from probing transcriptomes and future directions are provided. PMID- 30275274 TI - Clinical Significance of Pancreatic Atrophy Induced by Immune-Checkpoint Inhibitors: A Case-Control Study. AB - Immune-checkpoint inhibitor (ICI)-related diarrhea is attributed to inflammatory colitis, with no other drug-related differential diagnosis. Here, we investigated the occurrence of pancreatic atrophy (PA) in ICI-treated cancer patients and its correlation to exocrine pancreatic insufficiency (EPI). Metastatic melanoma, non small cell lung carcinoma, and head and neck squamous cell carcinoma patients (n = 403) treated with anti-PD-1 (n = 356) or anti-CTLA-4 (n = 47) were divided into a case group (radiologic evidence of PA); control group matched by age, gender, and previous lines of treatment; and colitis group (ICI-induced colitis). Quantitative pancreatic volumetry was used for calculation of the decrease in pancreatic volume over time (atrophy rate). Thirty-one patients (7.7%) developed PA compared with 41 matched controls (P = 0.006). Four patients developed EPI, all from the anti-PD-1-treated group, which resolved with oral enzyme supplementation. The atrophy rate did not correlate with EPI (P = 0.87). EPI related diarrhea presented at a median of 9 months, whereas the diarrhea of anti PD-1-induced colitis patients (n = 22) was presented at a median of 2 months (P = 0.029). ICI-induced PA is irreversible and can result in EPI. EPI should be suspected in cases of late-onset steroid-resistant diarrhea with features of steatorrhea and treated with oral enzyme supplements. PMID- 30275276 TI - The Story of RNA Folding, as Told in Epochs. AB - SUMMARYThe past decades have witnessed tremendous developments in our understanding of RNA biology. At the core of these advances have been studies aimed at discerning RNA structure and at understanding the forces that influence the RNA folding process. It is easy to take the present state of understanding for granted, but there is much to be learned by considering the path to our current understanding, which has been tortuous, with the birth and death of models, the adaptation of experimental tools originally developed for characterization of protein structure and catalysis, and the development of novel tools for probing RNA. In this review we tour the stages of RNA folding studies, considering them as "epochs" that can be generalized across scientific disciplines. These epochs span from the discovery of catalytic RNA, through biophysical insights into the putative primordial RNA World, to characterization of structured RNAs, the building and testing of models, and, finally, to the development of models with the potential to yield generalizable predictive and quantitative models for RNA conformational, thermodynamic, and kinetic behavior. We hope that this accounting will aid others as they navigate the many fascinating questions about RNA and its roles in biology, in the past, present, and future.

AB - Science policy offers a challenging and rewarding career path for scientists interested in the social, ethical, and legal implications of their field. This topic encompasses a broad spectrum of activities all in support of advancing the scientific enterprise. Science policy spans various sectors, and policy careers are found in many different organizations, including the federal government, scientific societies, and professional organizations. Although their specific duties may vary greatly, science policy professionals generally apply their scientific training to ensure that the scientific enterprise advances in a responsible and ethical manner and to solve challenges with broad scientific and societal implications. PMID- 30275278 TI - The Manganese-Dependent Pyruvate Kinase PykM Is Required for Wild-Type Glucose Utilization by Brucella abortus 2308 and Its Virulence in C57BL/6 Mice. AB - Pyruvate kinase plays a central role in glucose catabolism in bacteria, and efficient utilization of this hexose has been linked to the virulence of Brucella strains in mice. The brucellae produce a single pyruvate kinase which is an ortholog of the Bradyrhizobium manganese (Mn)-dependent pyruvate kinase PykM. A biochemical analysis of the Brucella pyruvate kinase and phenotypic analysis of a Brucella abortus mutant defective in high-affinity Mn import indicate that this enzyme is an authentic PykM ortholog which functions as a Mn-dependent enzyme in vivo The loss of PykM has a negative impact on the capacity of the parental 2308 strain to utilize glucose, fructose, and galactose but not on its ability to utilize ribose, xylose, arabinose, or erythritol, and a pykM mutant displays significant attenuation in C57BL/6 mice. Although the enzyme pyruvate phosphate dikinase (PpdK) can substitute for the loss of pyruvate kinase in some bacteria and is also an important virulence determinant in Brucella, a phenotypic analysis of B. abortus 2308 and isogenic pykM, ppdK, and pykM ppdK mutants indicates that PykM and PpdK make distinctly different contributions to carbon metabolism and virulence in these bacteria.IMPORTANCE Mn plays a critical role in the physiology and virulence of Brucella strains, and the results presented here suggest that one of the important roles that the high-affinity Mn importer MntH plays in the pathogenesis of these strains is supporting the function of the Mn-dependent kinase PykM. A better understanding of how the brucellae adapt their physiology and metabolism to sustain their intracellular persistence in host macrophages will provide knowledge that can be used to design improved strategies for preventing and treating brucellosis, a disease that has a significant impact on both the veterinary and public health communities worldwide. PMID- 30275279 TI - Co-assembly of SecYEG and SecA fully restores the properties of the native translocon. AB - In all cells a highly conserved channel transports proteins across membranes. In E.coli, that channel is SecYEG. Many investigations of this protein complex have used purified SecYEG reconstituted into proteoliposomes. How faithfully do activities of reconstituted systems reflect the properties of SecYEG in the native membrane environment? We investigated by comparing three in vitro systems: the native membrane environment of inner membrane vesicles and two methods of reconstitution. One method was the widely used reconstitution of SecYEG alone into lipid bilayers. The other was our method of co-assembly of SecYEG with SecA, the ATPase of the translocase. For nine different precursor species we assessed parameters that characterize translocation: maximal amplitude of competent precursor translocated, coupling of energy to transfer, and apparent rate constant. In addition we investigated translocation in the presence and absence of chaperone SecB. For all nine precursors, SecYEG co-assembled with SecA was as active as SecYEG in native membrane for each of the parameters studied. Effects of SecB on transport of precursors faithfully mimicked observations made in vivo From investigation of the nine different precursors, we conclude that the apparent rate constant, which reflects the step that limits the rate of translocation, is dependent on interactions with the translocon of portions of the precursors other than the leader. In addition, in some cases the rate limiting step is altered by the presence of SecB. Candidates for the rate limiting step that are consistent with our data are discussed. PMID- 30275280 TI - Methylation-Induced Hypermutation in Natural Populations of Bacteria. AB - Methylation of DNA at the C-5 position of cytosine occurs in diverse organisms. This modification can increase the rate of C->T transitions at the methylated position. In Escherichia coli and related enteric bacteria, the inner C residues of the sequence CCWGG (W is A or T) are methylated by the Dcm enzyme. These sites are hot spots of mutation during rapid growth in the laboratory but not in nondividing cells, in which repair by the Vsr protein is effective. It has been suggested that hypermutation at these sites is a laboratory artifact and does not occur in nature. Many other methyltransferases, with a variety of specificities, can be found in bacteria, usually associated with restriction enzymes and confined to a subset of the population. Their methylation targets are also possible sites of hypermutation. Here, I show using whole-genome sequence data for thousands of isolates that there is indeed considerable hypermutation at Dcm sites in natural populations: their transition rate is approximately eight times the average. I also demonstrate hypermutability of targets of restriction associated methyltransferases in several distantly related bacteria: methylation increases the transition rate by a factor ranging from 12 to 58. In addition, I demonstrate how patterns of hypermutability inferred from massive sequence data can be used to determine previously unknown methylation patterns and methyltransferase specificities.IMPORTANCE A common type of DNA modification, addition of a methyl group to cytosine (C) at carbon atom C-5, can greatly increase the rate of mutation of the C to a T. In mammals, methylation of CG sequences increases the rate of CG->TG mutations. It is unknown whether cytosine C-5 methylation increases the mutation rate in bacteria under natural conditions. I show that sites methylated by the Dcm enzyme exhibit an 8-fold increase in mutation rate in natural bacterial populations. I also show that modifications at other sites in various bacteria also increase the mutation rate, in some cases by a factor of forty or more. Finally, I demonstrate how this phenomenon can be used to infer sequence specificities of methylation enzymes. PMID- 30275281 TI - Simultaneous zygotic inactivation of multiple genes in mouse through CRISPR/Cas9 mediated base editing. AB - In vivo genetic mutation has become a powerful tool for dissecting gene function; however, multi-gene interaction and the compensatory mechanisms involved can make findings from single mutations, at best difficult to interpret, and, at worst, misleading. Hence, it is necessary to establish an efficient way to disrupt multiple genes simultaneously. CRISPR/Cas9-mediated base editing disrupts gene function by converting a protein-coding sequence into a stop codon; this is referred to as CRISPR-stop. Its application in generating zygotic mutations has not been well explored yet. Here, we first performed a proof-of-principle test by disrupting Atoh1, a gene crucial for auditory hair cell generation. Next, we individually mutated vGlut3 (Slc17a8), otoferlin (Otof) and prestin (Slc26a5), three genes needed for normal hearing function. Finally, we successfully disrupted vGlut3, Otof and prestin simultaneously. Our results show that CRISPR stop can efficiently generate single or triple homozygous F0 mouse mutants, bypassing laborious mouse breeding. We believe that CRISPR-stop is a powerful method that will pave the way for high-throughput screening of mouse developmental and functional genes, matching the efficiency of methods available for model organisms such as Drosophila. PMID- 30275282 TI - Use of a Metabolic Syndrome Severity Z Score to Track Risk During Treatment of Prediabetes: An Analysis of the Diabetes Prevention Program. AB - OBJECTIVE: We assessed whether changes in metabolic syndrome (MetS) severity during the treatment of prediabetes are associated with reduced risk of type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). RESEARCH DESIGN AND METHODS: We analyzed data from the Diabetes Prevention Program (DPP) for 2,476 adults in 1996-1999 with prediabetes randomized to receive treatment with lifestyle modification, metformin, or placebo for 2-3 years and followed through 2014 for T2DM and CVD outcomes. We calculated effect sizes from baseline in a MetS severity z score (MetS-Z) and the individual MetS components, and assessed relationships between 1-year effect size and incident T2DM and CVD using hazard ratios (HRs) and mediation analysis. RESULTS: Baseline MetS-Z and its components were associated with risk of incident T2DM and CVD. During year 1 of intervention, MetS-Z and its components decreased most with lifestyle modification, followed by treatment with metformin and placebo. Risk of T2DM within 1-5 years was most strongly associated with 1-year changes in MetS-Z and waist circumference (both HRs for a 1 SD increase = 1.80), whereas the risk of CVD was associated with a 1-year change in MetS-Z, glucose, and systolic blood pressure. In mediation analyses, the effect of lifestyle modification on T2DM risk was mediated by 1-year changes in MetS-Z, waist circumference, glucose, and triglycerides, whereas the effect of metformin was mediated by MetS-Z and glucose. CONCLUSIONS: Changes in these risk indicators of MetS severity during intervention in the DPP reflect altered disease risk and may help in tracking earlier responses to treatment and in motivating patients. PMID- 30275284 TI - An Automated Grading System for Detection of Vision-Threatening Referable Diabetic Retinopathy on the Basis of Color Fundus Photographs. AB - OBJECTIVE: The goal of this study was to describe the development and validation of an artificial intelligence-based, deep learning algorithm (DLA) for the detection of referable diabetic retinopathy (DR). RESEARCH DESIGN AND METHODS: A DLA using a convolutional neural network was developed for automated detection of vision-threatening referable DR (preproliferative DR or worse, diabetic macular edema, or both). The DLA was tested by using a set of 106,244 nonstereoscopic retinal images. A panel of ophthalmologists graded DR severity in retinal photographs included in the development and internal validation data sets (n = 71,043); a reference standard grading was assigned once three graders achieved consistent grading outcomes. For external validation, we tested our DLA using 35,201 images of 14,520 eyes (904 eyes with any DR; 401 eyes with vision threatening referable DR) from population-based cohorts of Malays, Caucasian Australians, and Indigenous Australians. RESULTS: Among the 71,043 retinal images in the training and validation data sets, 12,329 showed vision-threatening referable DR. In the internal validation data set, the area under the curve (AUC), sensitivity, and specificity of the DLA for vision-threatening referable DR were 0.989, 97.0%, and 91.4%, respectively. Testing against the independent, multiethnic data set achieved an AUC, sensitivity, and specificity of 0.955, 92.5%, and 98.5%, respectively. Among false-positive cases, 85.6% were due to a misclassification of mild or moderate DR. Undetected intraretinal microvascular abnormalities accounted for 77.3% of all false-negative cases. CONCLUSIONS: This artificial intelligence-based DLA can be used with high accuracy in the detection of vision-threatening referable DR in retinal images. This technology offers potential to increase the efficiency and accessibility of DR screening programs. PMID- 30275283 TI - Atherosclerosis and Microvascular Complications: Results From the Canadian Study of Longevity in Type 1 Diabetes. AB - OBJECTIVE: Type 1 diabetes carries a significant risk for cardiovascular mortality, but it is unclear how atherosclerosis associates with microvascular complications. We aimed to determine the relationships between atherosclerotic burden and neuropathy, retinopathy, and diabetic kidney disease (DKD) in adults with a >=50-year history of type 1 diabetes. RESEARCH DESIGN AND METHODS: Adults with type 1 diabetes (n = 69) underwent coronary artery calcification (CAC) volume scoring by wide-volume computerized tomography. Microvascular complications were graded as follows: neuropathy by clinical assessment, electrophysiology, vibration and cooling detection thresholds, heart rate variability, and corneal confocal microscopy; retinopathy by ultra-wide-field retinal imaging; and DKD by renal hemodynamic function measured by inulin and para-aminohippurate clearance at baseline and after intravenous infusion of angiotensin II. The cohort was dichotomized to high (>=300 Agatston units [AU]) or low (<300 AU) CAC and was stratified by diabetes status. A comparator group without diabetes (n = 73) matched for age and sex also underwent all study procedures except for retinal imaging. RESULTS: CAC scores were higher in participants with type 1 diabetes (median Agatston score 1,000 [interquartile range = 222, 2,373] AU vs. 1 [0.75] AU in comparators, P < 0.001). In participants with type 1 diabetes, high CAC scores associated with markers of neuropathy and retinopathy, but not with DKD, or renal hemodynamic function at baseline or in response to angiotensin II. CONCLUSIONS: The presence of high CAC in adults with longstanding type 1 diabetes was associated with large nerve fiber neuropathy and retinopathy but not with renal hemodynamic function, suggesting that neuropathy, retinopathy, and macrovascular calcification share common risk factors.

AB - OBJECTIVE: The type 2 diabetes-associated alleles at the TCF7L2 locus mark a type 1 diabetes phenotype characterized by single islet autoantibody positivity as well as lower glucose and higher C-peptide measures. Here, we studied whether the TCF7L2 locus influences progression of islet autoimmunity, from single to multiple (>=2) autoantibody positivity, in relatives of patients with type 1 diabetes. RESEARCH DESIGN AND METHODS: We evaluated 244 participants in the Type 1 Diabetes TrialNet Pathway to Prevention study with confirmed single autoantibody positivity at screening and Immunochip single nucleotide polymorphism data (47.5% male; median age 12.8 years, range 1.2-45.9; 90.2% white). We analyzed risk allele frequency at TCF7L2 rs4506565 (in linkage disequilibrium with rs7903146). Altogether, 62.6% participants carried >=1 risk allele. Univariate and multivariable Cox proportional hazards models and Kaplan Meier statistical methods were used. RESULTS: During follow-up (median 5.2 years, range 0.2-12.6), 62% of the single autoantibody-positive participants developed multiple autoantibody positivity. In the overall cohort, the TCF7L2 locus did not significantly predict progression to multiple autoantibody positivity. However, among single GAD65 autoantibody-positive participants (n = 158), those who carried >=1 risk allele had a lower rate of progression to multiple autoantibody positivity (hazard ratio [HR] 0.65, P = 0.033) than those who did not, after adjustment for HLA risk haplotypes and age. Among subjects who were either IA-2 or insulin autoantibody positive only, carrying >=1 TCF7L2 risk allele was not a significant factor overall, but in overweight or obese participants, it increased the risk of progression to multiple autoantibody positivity (HR 3.02, P = 0.016) even with adjustment for age. CONCLUSIONS: The type 2 diabetes-associated TCF7L2 locus influences progression of islet autoimmunity, with differential effects by autoantibody specificity and interaction by obesity/overweight.

PMID- 30275293 TI - Functional muscle recovery with nanoparticle-directed M2 macrophage polarization in mice. AB - Persistence of inflammation, and associated limits in tissue regeneration, are believed to be due in part to the imbalance of M1 over M2 macrophages. Here, we hypothesized that providing a sustained source of an antiinflammatory polarizing cytokine would shift the balance of macrophages at a site of tissue damage to improve functional regeneration. Specifically, IL-4-conjugated gold nanoparticles (PA4) were injected into injured murine skeletal muscle, resulting in improved histology and an ~40% increase in muscle force compared with mice treated with vehicle only. Macrophages were the predominant infiltrating immune cell, and treatment with PA4 resulted in an approximately twofold increase in the percentage of macrophages expressing the M2a phenotype and an approximately twofold decrease in M1 macrophages, compared with mice treated with vehicle only. Intramuscular injection of soluble IL-4 did not shift macrophage polarization or result in functional muscle improvements. Depletion of monocytes/macrophages eliminated the therapeutic effects of PA4, suggesting that improvement in muscle function was the result of M2-shifted macrophage polarization. The ability of PA4 to direct macrophage polarization in vivo may be beneficial in the treatment of many injuries and inflammatory diseases.

AB - Proximity to industrial facilities can have positive employment effects as well as negative pollution exposure impacts on surrounding communities. Although racial disparities in exposure to industrial air pollution in the United States are well documented, there has been little empirical investigation of whether these disparities are mirrored by employment benefits. We use facility-level data from the US Environmental Protection Agency (EPA) Toxics Release Inventory (TRI) and the US Equal Employment Opportunity Commission EEO-1 database to assess the extent to which the racial and ethnic distribution of industrial employment corresponds to the distribution of exposure to air toxics emitted by the same facilities. The share of pollution risk accruing to minority groups generally exceeds their share of employment and exceeds their share of higher paying jobs by a wide margin. We find no evidence that facilities that create higher pollution risk for surrounding communities provide more jobs in aggregate. PMID- 30275294 TI - Diplogastrellus nematodes are sexually transmitted mutualists that alter the bacterial and fungal communities of their beetle host. AB - A recent accumulation of studies has demonstrated that nongenetic, maternally transmitted factors are often critical to the health and development of offspring and can therefore play a role in ecological and evolutionary processes. In particular, microorganisms such as bacteria have been championed as heritable, symbiotic partners capable of conferring fitness benefits to their hosts. At the same time, parents may also pass various nonmicrobial organisms to their offspring, yet the roles of such organisms in shaping the developmental environment of their hosts remain largely unexplored. Here, we show that the nematode Diplogastrellus monhysteroides is transgenerationally inherited and sexually transmitted by the dung beetle Onthophagus taurus By manipulating artificial chambers in which beetle offspring develop, we demonstrate that the presence of D. monhysteroides nematodes enhances the growth of beetle offspring, empirically challenging the paradigm that nematodes are merely commensal or even detrimental to their insect hosts. Finally, our research presents a compelling mechanism whereby the nematodes influence the health of beetle larvae: D. monhysteroides nematodes engineer the bacterial and fungal communities that also inhabit the beetle developmental chambers, including specific taxa known to be involved in biomass degradation, possibly allowing larval beetles better access to their otherwise recalcitrant, plant-based diet. Thus, our findings illustrate that nongenetic inheritance can include intermediately sized organisms that live and proliferate in close association with, and in certain cases enhance, the development of their hosts' offspring.

AB - Memory T helper (mTh) cells play important roles in the reinfection of pathogens and drive the pathogenesis of diseases. While recent studies have characterized the pathogenic mTh2 cell subpopulations driving allergic inflammation, those that induce immune responses against helminth infection remain unknown. We found that IL-5-producing CXCR6+ST2+CD44+ mTh2 cells play a crucial role in the IL-33 dependent inhibition of the fecundity of helminth, whereas other ST2- mTh2 cells do not. Although both cell types induced the infiltration of granulocytes, especially eosinophils, into the lungs in response to helminth infection, the ST2+ mTh2 cell-induced eosinophils expressed higher levels of major basic protein (MBP), which is important for reducing the fecundity of Nippostrongylus brasiliensis (Nb), than ST2- mTh2 cell-induced ones. Notably, we also found that ST2+ Treg cells but not ST2- Treg cells suppressed CXCR6+ST2+ mTh2 cell-mediated immune responses. Taken together, these findings show that we identified a mechanism against helminth elicited by a subpopulation of IL-5-producing mTh2 cells through the accumulation of eosinophils strongly expressing MBP in the lungs.

AB - The peptidoglycan (PG) layer stabilizes the bacterial cell envelope to maintain the integrity and shape of the cell. Penicillin-binding proteins (PBPs) synthesize essential 4-3 cross-links in PG and are inhibited by beta-lactam antibiotics. Some clinical isolates and laboratory strains of Enterococcus faecium and Escherichia coli achieve high-level beta-lactam resistance by utilizing beta-lactam-insensitive LD-transpeptidases (LDTs) to produce exclusively 3-3 cross-links in PG, bypassing the PBPs. In E. coli, other LDTs covalently attach the lipoprotein Lpp to PG to stabilize the envelope and maintain the permeability barrier function of the outermembrane. Here we show that subminimal inhibitory concentration of copper chloride sensitizes E. coli cells to sodium dodecyl sulfate and impair survival upon LPS transport stress, indicating reduced cell envelope robustness. Cells grown in the presence of copper chloride lacked 3-3 cross-links in PG and displayed reduced covalent attachment of Braun's lipoprotein and reduced incorporation of a fluorescent d amino acid, suggesting inhibition of LDTs. Copper dramatically decreased the minimal inhibitory concentration of ampicillin in E. coli and E. faecium strains with a resistance mechanism relying on LDTs and inhibited purified LDTs at submillimolar concentrations. Hence, our work reveals how copper affects bacterial cell envelope stability and counteracts LDT-mediated beta-lactam resistance. PMID- 30275299 TI - Tradeoffs in environmental and equity gains from job accessibility. AB - Increasing job accessibility is considered key to urban sustainability progress, both from an environmental and from a social perspective. However, sustainability outcomes depend on the processes contributing to accessibility trends, not just the trends themselves. Here, we ask whether sustainability benefits have followed from accessibility trends in the United States. We measure changes in accessibility from 2002 to 2014 across 909 US urban areas and decompose these changes to understand underlying infrastructure and land use processes. Our results show that job accessibility has increased across 74% of urban areas for the average resident, using both cars and transit. However, most of these accessibility gains were not achieved in ways that are inherently beneficial to environmental or social sustainability. In some urban areas, accessibility increases were conducive to reducing emissions, while in others, accessibility increases were conducive to reducing social inequities. However, accessibility increases almost never created a simultaneous social and environmental "win-win," as is often assumed. Our findings highlight how the spatial patterns of urbanization create tradeoffs between different facets of sustainability. Identifying where social objectives take precedence over environmental objectives (or vice versa) could help determine how accessibility increases can be accomplished to contribute to a more sustainable urban future. PMID- 30275298 TI - Two are better than one: Infant language learning from video improves in the presence of peers. AB - Studies show that young children learn new phonemes and words from humans significantly better than from machines. However, it is not clear why learning from video is ineffective or what might be done to improve learning from a screen. The present study, conducted with 9-month-old infants, utilized a manipulation-touch screen video-which allowed infants to control presentations of foreign-language video clips. We tested the hypothesis that infant learning from a screen would be enhanced in the presence of a peer, as opposed to learning alone. Brain measures of phonetic learning and detailed analyses of interaction during learning confirm the hypothesis that social partners enhance learning, even from screens. PMID- 30275300 TI - HSP90 is a chaperone for DLK and is required for axon injury signaling. AB - Peripheral nerve injury induces a robust proregenerative program that drives axon regeneration. While many regeneration-associated genes are known, the mechanisms by which injury activates them are less well-understood. To identify such mechanisms, we performed a loss-of-function pharmacological screen in cultured adult mouse sensory neurons for proteins required to activate this program. Well characterized inhibitors were present as injury signaling was induced but were removed before axon outgrowth to identify molecules that block induction of the program. Of 480 compounds, 35 prevented injury-induced neurite regrowth. The top hits were inhibitors to heat shock protein 90 (HSP90), a chaperone with no known role in axon injury. HSP90 inhibition blocks injury-induced activation of the proregenerative transcription factor cJun and several regeneration-associated genes. These phenotypes mimic loss of the proregenerative kinase, dual leucine zipper kinase (DLK), a critical neuronal stress sensor that drives axon degeneration, axon regeneration, and cell death. HSP90 is an atypical chaperone that promotes the stability of signaling molecules. HSP90 and DLK show two hallmarks of HSP90-client relationships: (i) HSP90 binds DLK, and (ii) HSP90 inhibition leads to rapid degradation of existing DLK protein. Moreover, HSP90 is required for DLK stability in vivo, where HSP90 inhibitor reduces DLK protein in the sciatic nerve. This phenomenon is evolutionarily conserved in Drosophila Genetic knockdown of Drosophila HSP90, Hsp83, decreases levels of Drosophila DLK, Wallenda, and blocks Wallenda-dependent synaptic terminal overgrowth and injury signaling. Our findings support the hypothesis that HSP90 chaperones DLK and is required for DLK functions, including proregenerative axon injury signaling. PMID- 30275301 TI - Measures of single- versus multiple-round translation argue against a mechanism to ensure coupling of transcription and translation. AB - In prokaryotes, the synthesis of RNA and protein occurs simultaneously in the cytoplasm. A number of studies indicate that translation can strongly impact transcription, a phenomenon often attributed to physical coupling between RNA polymerase (RNAP) and the lead ribosome on the nascent mRNA. Whether there generally exists a mechanism to ensure or promote RNAP-ribosome coupling remains unclear. Here, we used an efficient hammerhead ribozyme and developed a reporter system to measure single- versus multiple-round translation in Escherichia coli Six pairs of cotranscribed and differentially translated genes were analyzed. For five of them, the stoichiometry of the two protein products came no closer to unity (1:1) when the rounds of translation were severely reduced in wild-type cells. Introduction of mutation rpoB(I572N), which slows RNAP elongation, could promote coupling, as indicated by stoichiometric SspA and SspB products in the single-round assay. These data are consistent with models of stochastic coupling in which the probability of coupling depends on the relative rates of transcription and translation and suggest that RNAP often transcribes without a linked ribosome. PMID- 30275302 TI - Space radiation triggers persistent stress response, increases senescent signaling, and decreases cell migration in mouse intestine. AB - Proliferative gastrointestinal (GI) tissue is radiation-sensitive, and heavy-ion space radiation with its high-linear energy transfer (high-LET) and higher damaging potential than low-LET gamma-rays is predicted to compromise astronauts' GI function. However, much uncertainty remains in our understanding of how heavy ions affect coordinated epithelial cell migration and extrusion, which are essential for GI homeostasis. Here we show using mouse small intestine as a model and BrdU pulse labeling that cell migration along the crypt-villus axis is persistently decreased after a low dose of heavy-ion 56Fe radiation relative to control and gamma-rays. Wnt/beta-catenin and its downstream EphrinB/EphB signaling are key to intestinal epithelial cell (IEC) proliferation and positioning during migration, and both are up-regulated after 56Fe radiation. Conversely, factors involved in cell polarity and adhesion and cell-extracellular matrix interactions were persistently down-regulated after 56Fe irradiation potentially altering cytoskeletal remodeling and cell extrusion. 56Fe radiation triggered a time-dependent increase in gammaH2AX foci and senescent cells but without a noticeable increase in apoptosis. Some senescent cells acquired the senescence-associated secretory phenotype, and this was accompanied by increased IEC proliferation, implying a role for progrowth inflammatory factors. Collectively, this study demonstrates a unique phenomenon of heavy-ion radiation induced persistently delayed IEC migration involving chronic sublethal genotoxic and oncogenic stress-induced altered cytoskeletal dynamics, which were seen even a year later. When considered along with changes in barrier function and nutrient absorption factors as well as increased intestinal tumorigenesis, our in vivo data raise a serious concern for long-duration deep-space manned missions. PMID- 30275303 TI - Effect of sequential video shot comprehensibility on attentional synchrony: A comparison of children and adults. AB - To comprehend edited video, viewers must infer the meaning conveyed by successive video shots (i.e., continuous video segments separated by edit points, such as camera cuts). The central question here was whether comprehension-related top down cognitive processes drive eye movements during sequential processing of video montage. Eye movements were recorded as 4 year olds and adults (n = 62) watched a video with the same constituent shots in either normal or random sequence. The key analyses compared eye movements to constituent shots when presented in normal order with those to the same shots presented in random order. The dependent variable was attentional synchrony or the extent to which viewers looked at the same location at the same time, indicating commonality of processing the video. This was calculated as the bivariate contour ellipse area within which points of gaze fell during each video frame. Results indicated that children were more scattered in their gaze locations than adults. Viewers became more similar to each other as normal vignettes unfolded over time; this was especially true in adults and possibly reflects a growing and shared understanding of the content. Conversely, adult attentional synchrony was reduced when watching random shot sequences. Thus, attentional synchrony during normal video viewing is driven not only by salient visual features, such as movement and areas of high contrast, but also, by the unfolding sequential comprehension of video montage, especially in adults. Differences between children and adults indicate that this top-down control of eye movements while watching video changes systematically over development.

PMID- 30275304 TI - Maize yields over Europe may increase in spite of climate change, with an appropriate use of the genetic variability of flowering time. AB - Projections based on invariant genotypes and agronomic practices indicate that climate change will largely decrease crop yields. The comparatively few studies considering farmers' adaptation result in a diversity of impacts depending on their assumptions. We combined experiments and process-based modeling for analyzing the consequences of climate change on European maize yields if farmers made the best use of the current genetic variability of cycle duration, based on practices they currently use. We first showed that the genetic variability of maize flowering time is sufficient for identifying a cycle duration that maximizes yield in a range of European climatic conditions. This was observed in six field experiments with a panel of 121 accessions and extended to 59 European sites over 36 years with a crop model. The assumption that farmers use optimal cycle duration and sowing date was supported by comparison with historical data. Simulations were then carried out for 2050 with 3 million combinations of crop cycle durations, climate scenarios, management practices, and modeling hypotheses. Simulated grain production over Europe in 2050 was stable (-1 to +1%) compared with the 1975-2010 baseline period under the hypotheses of unchanged cycle duration, whereas it was increased (+4-7%) when crop cycle duration and sowing dates were optimized in each local environment. The combined effects of climate change and farmer adaptation reduced the yield gradient between south and north of Europe and increased European maize production if farmers continued to make the best use of the genetic variability of crop cycle duration. PMID- 30275306 TI - Metaanalysis of the relationship between violent video game play and physical aggression over time. AB - To clarify and quantify the influence of video game violence (VGV) on aggressive behavior, we conducted a metaanalysis of all prospective studies to date that assessed the relation between exposure to VGV and subsequent overt physical aggression. The search strategy identified 24 studies with over 17,000 participants and time lags ranging from 3 months to 4 years. The samples comprised various nationalities and ethnicities with mean ages from 9 to 19 years. For each study we obtained the standardized regression coefficient for the prospective effect of VGV on subsequent aggression, controlling for baseline aggression. VGV was related to aggression using both fixed [beta = 0.113, 95% CI = (0.098, 0.128)] and random effects models [beta = 0.106 (0.078, 0.134)]. When all available covariates were included, the size of the effect remained significant for both models [beta = 0.080 (0.065, 0.094) and beta = 0.078 (0.053, 0.102), respectively]. No evidence of publication bias was found. Ethnicity was a statistically significant moderator for the fixed-effects models (P <= 0.011) but not for the random-effects models. Stratified analyses indicated the effect was largest among Whites, intermediate among Asians, and nonsignificant among Hispanics. Discussion focuses on the implications of such findings for current debates regarding the effects of violent video games on physical aggression. PMID- 30275307 TI - Mutations in the DNA demethylase OsROS1 result in a thickened aleurone and improved nutritional value in rice grains. AB - The rice endosperm, consisting of an outer single-cell layer aleurone and an inner starchy endosperm, is an important staple food for humans. While starchy endosperm stores mainly starch, the aleurone is rich in an array of proteins, vitamins, and minerals. To improve the nutritional value of rice, we screened for mutants with thickened aleurones using a half-seed assay and identified thick aleurone 2-1 (ta2-1), in which the aleurone has 4.8 +/- 2.2 cell layers on average. Except for starch, the contents of all measured nutritional factors, including lipids, proteins, vitamins, minerals, and dietary fibers, were increased in ta2-1 grains. Map-based cloning showed that TA2 encodes the DNA demethylase OsROS1. A point mutation in the 14th intron of OsROS1 led to alternative splicing that generated an extra transcript, mOsROS1, with a 21-nt insertion from the intron. Genetic analyses showed that the ta2-1 phenotype is inherited with an unusual gametophytic maternal effect, which is caused not by imprinted gene expression but rather by the presence of the mOsROS1 transcript. Five additional ta2 alleles with the increased aleurone cell layer and different inheritance patterns were identified by TILLING. Genome-wide bisulfite sequencing revealed general increases in CG and CHG methylations in ta2-1 endosperms, along with hypermethylation and reduced expression in two putative aleurone differentiation-related transcription factors. This study thus suggests that OsROS1-mediated DNA demethylation restricts the number of aleurone cell layers in rice and provides a way to improve the nutrition of rice. PMID- 30275308 TI - Bypassing a 8,5'-cyclo-2'-deoxyadenosine lesion by human DNA polymerase eta at atomic resolution. AB - Oxidatively induced DNA lesions 8,5'-cyclopurine-2'-deoxynucleosides (cdPus) are prevalent and cytotoxic by impeding DNA replication and transcription. Both the 5'R- and 5'S-diastereomers of cdPu can be removed by nucleotide excision repair; however, the 5'S-cdPu is more resistant to repair than the 5'R counterpart. Here, we report the crystal structures of human polymerase (Pol) eta bypassing 5'S-8,5' cyclo-2'-deoxyadenosine (cdA) in insertion and the following two extension steps. The cdA-containing DNA structures vary in response to the protein environment. Supported by the "molecular splint" of Pol eta, the structure of 5'S-cdA at 1.75 A resolution reveals that the backbone is pinched toward the minor groove and the adenine base is tilted. In the templating position, the cdA takes up the extra space usually reserved for the thymine dimer, and dTTP is efficiently incorporated by Pol eta in the presence of Mn2+ Rigid distortions of the DNA duplex by cdA, however, prevent normal base pairing and hinder immediate primer extension by Pol eta. Our results provide structural insights into the strong replication blockage effect and the mutagenic property of the cdPu lesions in cells. PMID- 30275310 TI - Bayesian approach to SETI. AB - The search for technosignatures from hypothetical galactic civilizations is going through a new phase of intense activity. For the first time, a significant fraction of the vast search space is expected to be sampled in the foreseeable future, potentially bringing informative data about the abundance of detectable extraterrestrial civilizations or the lack thereof. Starting from the current state of ignorance about the galactic population of nonnatural electromagnetic signals, we formulate a Bayesian statistical model to infer the mean number of radio signals crossing Earth, assuming either nondetection or the detection of signals in future surveys of the Galaxy. Under fairly noninformative priors, we find that not detecting signals within about 1 kly from Earth, while suggesting the lack of galactic emitters or at best the scarcity thereof, is nonetheless still consistent with a probability exceeding 10% that typically over [Formula: see text] signals could be crossing Earth, with radiated power analogous to that of the Arecibo radar, but coming from farther in the Milky Way. The existence in the Galaxy of potentially detectable Arecibo-like emitters can be reasonably ruled out only if all-sky surveys detect no such signals up to a radius of about 40 kly, an endeavor requiring detector sensitivities thousands times higher than those of current telescopes. Conversely, finding even one Arecibo-like signal within [Formula: see text] light years, a possibility within reach of current detectors, implies almost certainly that typically more than [Formula: see text] signals of comparable radiated power cross the Earth, yet to be discovered. PMID- 30275309 TI - Lesion network localization of free will. AB - Our perception of free will is composed of a desire to act (volition) and a sense of responsibility for our actions (agency). Brain damage can disrupt these processes, but which regions are most important for free will perception remains unclear. Here, we study focal brain lesions that disrupt volition, causing akinetic mutism (n = 28), or disrupt agency, causing alien limb syndrome (n = 50), to better localize these processes in the human brain. Lesion locations causing either syndrome were highly heterogeneous, occurring in a variety of different brain locations. We next used a recently validated technique termed lesion network mapping to determine whether these heterogeneous lesion locations localized to specific brain networks. Lesion locations causing akinetic mutism all fell within one network, defined by connectivity to the anterior cingulate cortex. Lesion locations causing alien limb fell within a separate network, defined by connectivity to the precuneus. Both findings were specific for these syndromes compared with brain lesions causing similar physical impairments but without disordered free will. Finally, our lesion-based localization matched network localization for brain stimulation locations that disrupt free will and neuroimaging abnormalities in patients with psychiatric disorders of free will without overt brain lesions. Collectively, our results demonstrate that lesions in different locations causing disordered volition and agency localize to unique brain networks, lending insight into the neuroanatomical substrate of free will perception. PMID- 30275311 TI - Early adolescent Rai1 reactivation reverses transcriptional and social interaction deficits in a mouse model of Smith-Magenis syndrome. AB - Haploinsufficiency of Retinoic Acid Induced 1 (RAI1) causes Smith-Magenis syndrome (SMS), a syndromic autism spectrum disorder associated with craniofacial abnormalities, intellectual disability, and behavioral problems. There is currently no cure for SMS. Here, we generated a genetic mouse model to determine the reversibility of SMS-like neurobehavioral phenotypes in Rai1 heterozygous mice. We show that normalizing the Rai1 level 3-4 wk after birth corrected the expression of genes related to neural developmental pathways and fully reversed a social interaction deficit caused by Rai1 haploinsufficiency. In contrast, Rai1 reactivation 7-8 wk after birth was not beneficial. We also demonstrated that the correct Rai1 dose is required in both excitatory and inhibitory neurons for proper social interactions. Finally, we found that Rai1 heterozygous mice exhibited a reduction of dendritic spines in the medial prefrontal cortex (mPFC) and that optogenetic activation of mPFC neurons in adults improved the social interaction deficit of Rai1 heterozygous mice. Together, these results suggest the existence of a postnatal temporal window during which restoring Rai1 can improve the transcriptional and social behavioral deficits in a mouse model of SMS. It is possible that circuit-level interventions would be beneficial beyond this critical window. PMID- 30275312 TI - Minds and brains of media multitaskers: Current findings and future directions. AB - Media and technology are ubiquitous elements of our daily lives, and their use can offer many benefits and rewards. At the same time, decisions about how individuals structure their use of media can be informed by consideration of whether, and if so how, the mind and brain are shaped by different use patterns. Here we review the growing body of research that investigates the cognitive and neural profiles of individuals who differ in the extent to which they simultaneously engage with multiple media streams, or "media multitasking." While the literature is still sparse, and is marked by both convergent and divergent findings, the balance of evidence suggests that heavier media multitaskers exhibit poorer performance in a number of cognitive domains, relative to lighter media multitaskers (although many studies find no performance differences between groups). When evidence points to a relationship between media multitasking level and cognition, it is often on tasks that require or are influenced by fluctuations in sustained goal-directed attention. Given the real-world significance of such findings, further research is needed to uncover the mechanistic underpinnings of observed differences, to determine the direction of causality, to understand whether remediation efforts are needed and effective, and to determine how measurement heterogeneity relates to variable outcomes. Such efforts will ultimately inform decisions about how to minimize the potential costs and maximize the many benefits of our ever-evolving media landscape. PMID- 30275313 TI - Changes in resource partitioning between and within organs support growth adjustment to neighbor proximity in Brassicaceae seedlings. AB - In shade-intolerant plants, the perception of proximate neighbors rapidly induces architectural changes resulting in elongated stems and reduced leaf size. Sensing and signaling steps triggering this modified growth program have been identified. However, the underlying changes in resource allocation that fuel stem growth remain poorly understood. Through 14CO2 pulse labeling of Brassica rapa seedlings, we show that perception of the neighbor detection signal, low ratio of red to far-red light (R:FR), leads to increased carbon allocation from the major site of photosynthesis (cotyledons) to the elongating hypocotyl. While carbon fixation and metabolite levels remain similar in low R:FR, partitioning to all downstream carbon pools within the hypocotyl is increased. Genetic analyses using Arabidopsis thaliana mutants indicate that low-R:FR-induced hypocotyl elongation requires sucrose transport from the cotyledons and is regulated by a PIF7 dependent metabolic response. Moreover, our data suggest that starch metabolism in the hypocotyl has a growth-regulatory function. The results reveal a key mechanism by which metabolic adjustments can support rapid growth adaptation to a changing environment. PMID- 30275314 TI - Natural forcing of the North Atlantic nitrogen cycle in the Anthropocene. AB - Human alteration of the global nitrogen cycle intensified over the 1900s. Model simulations suggest that large swaths of the open ocean, including the North Atlantic and the western Pacific, have already been affected by anthropogenic nitrogen through atmospheric transport and deposition. Here we report an ~130 year-long record of the 15N/14N of skeleton-bound organic matter in a coral from the outer reef of Bermuda, which provides a test of the hypothesis that anthropogenic atmospheric nitrogen has significantly augmented the nitrogen supply to the open North Atlantic surface ocean. The Bermuda 15N/14N record does not show a long-term decline in the Anthropocene of the amplitude predicted by model simulations or observed in a western Pacific coral 15N/14N record. Rather, the decadal variations in the Bermuda 15N/14N record appear to be driven by the North Atlantic Oscillation, most likely through changes in the formation rate of Subtropical Mode Water. Given that anthropogenic nitrogen emissions have been decreasing in North America since the 1990s, this study suggests that in the coming decades, the open North Atlantic will remain minimally affected by anthropogenic nitrogen deposition. PMID- 30275315 TI - How to play 20 questions with nature and lose: Reflections on 100 years of brain training research. AB - Despite dozens of empirical studies and a growing body of meta-analytic work, there is little consensus regarding the efficacy of cognitive training. In this review, we examine why this substantial corpus has failed to answer the often asked question, "Does cognitive training work?" We first define cognitive training and discuss the general principles underlying training interventions. Next, we review historical interventions and discuss how findings from this early work remain highly relevant for current cognitive-training research. We highlight a variety of issues preventing real progress in understanding the underlying mechanisms of training, including the lack of a coherent theoretical framework to guide training research and methodological issues across studies and meta analyses. Finally, suggestions for correcting these issues are offered in the hope that we might make greater progress in the next 100 y of cognitive-training research. PMID- 30275316 TI - Entropically driven aggregation of bacteria by host polymers promotes antibiotic tolerance in Pseudomonas aeruginosa. AB - Bacteria causing chronic infections are generally observed living in cell aggregates suspended in polymer-rich host secretions, and bacterial phenotypes induced by aggregated growth may be key factors in chronic infection pathogenesis. Bacterial aggregation is commonly thought of as a consequence of biofilm formation; however the mechanisms producing aggregation in vivo remain unclear. Here we show that polymers that are abundant at chronic infection sites cause bacteria to aggregate by the depletion aggregation mechanism, which does not require biofilm formation functions. Depletion aggregation is mediated by entropic forces between uncharged or like-charged polymers and particles (e.g., bacteria). Our experiments also indicate that depletion aggregation of bacteria induces marked antibiotic tolerance that was dependent on the SOS response, a stress response activated by genotoxic stress. These findings raise the possibility that targeting conditions that promote depletion aggregation or mechanisms of depletion-mediated tolerance could lead to new therapeutic approaches to combat chronic bacterial infections. PMID- 30275317 TI - Role of PDGF receptor-alpha during human cytomegalovirus entry into fibroblasts. AB - Human CMV (HCMV) exhibits a broad cell tropism that depends on two virion glycoprotein complexes: a trimeric complex (gH/gL/gO) that facilitates viral infection primarily in fibroblasts and a pentameric complex (gH/gL/pUL128-pUL130 pUL131A) that mediates infection in epithelial and endothelial cells. We performed genome-wide CRISPR screens in which the PDGF receptor-alpha (PDGFRalpha) was identified as the most significant cellular gene product essential for infection by HCMV virions containing only trimeric complex (trimer only virus). Trimer-only virus did not enter PDGFRalpha knockout fibroblasts. By using knockout fibroblasts, the extracellular domain of PDGFRalpha required for virus entry was mapped, and the intracellular tyrosine kinase domain was shown to be nonessential. In addition, direct cell-to-cell spread of virus from knockout cells transfected with trimer-only viral DNA was blocked, despite the production of infectious virus in the transfected cells. In contrast to trimer-only virus, wild-type HCMV virions containing both trimeric and pentameric complexes entered PDGFRalpha knockout cells, reinforcing the view that fibroblasts contain a second, independent receptor for the pentameric complex. Importantly, however, wild-type virus entered the knockout fibroblasts at reduced efficiency compared with parental fibroblasts, arguing that the cellular receptor for the virion pentameric complex is limiting or that virions are produced containing different relative amounts of the two glycoprotein complexes. Finally, ectopic expression of PDGFRalpha in ARPE-19 epithelial cells and THP-1 monocytic cells, which have little to no endogenous PDGFRalpha expression, markedly enhanced their susceptibility to trimer-only virions. In sum, our data clarify several key determinants of HCMV tropism. PMID- 30275318 TI - Screen media use and ADHD-related behaviors: Four decades of research. AB - The diagnosis of attention-deficit/hyperactivity disorder (ADHD) among children and adolescents has increased considerably over the past decades. Scholars and health professionals alike have expressed concern about the role of screen media in the rise in ADHD diagnosis. However, the extent to which screen media use and ADHD are linked remains a point of debate. To understand the current state of the field and, ultimately, move the field forward, we provide a systematic review of the literature on the relationship between children and adolescents' screen media use and ADHD-related behaviors (i.e., attention problems, hyperactivity, and impulsivity). Using the Differential Susceptibility to Media effects Model as a theoretical lens, we systematically organize the existing literature, identify potential shortcomings in this literature, and provide directions for future research. The available evidence suggests a statistically small relationship between media and ADHD-related behaviors. Evidence also suggests that individual child differences, such as gender and trait aggression, may moderate this relationship. There is a clear need for future research that investigates causality, underlying mechanisms, and differential susceptibility to the effects of screen media use on ADHD-related behaviors. It is only through a richer empirical body that we will be able to fully understand the media-ADHD relationship. PMID- 30275320 TI - Unique size-dependent nanocatalysis revealed at the single atomically precise gold cluster level. AB - Atomically precise metal clusters have attracted increasing interest owing to their unique size-dependent properties; however, little has been known about the effect of size on the catalytic properties of metal clusters at the single cluster level. Here, by real-time monitoring with single-molecule fluorescence microscopy the size-dependent catalytic process of individual Au clusters at single-turnover resolution, we study the size-dependent catalytic behaviors of gold (Au) clusters at the single-cluster level, and then observe the strong size effect on the catalytic properties of individual Au clusters, in both catalytic product formation and dissociation processes. Surprisingly, indicated by both experiments and density functional theory (DFT) calculations, due to such a unique size effect, besides observing the different product dissociation behaviors on different-sized Au clusters, we also observe that small Au clusters [i.e., Au15(MPA)13; here, MPA denotes 3-mercaptopropionic acid] catalyze the product formation through a competitive Langmuir-Hinshelwood mechanism, while those relatively larger Au clusters [e.g., Au18(MPA)14 and Au25(MPA)18] or nanoparticles catalyze the same process through a noncompetitive Langmuir Hinshelwood mechanism. Such a size effect on the nanocatalysis could be attributed intrinsically to the size-dependent electronic structure of Au clusters. Further analysis of dynamic activity fluctuation of Au clusters reveals more different catalytic properties between Au clusters and traditional Au nanoparticles due to their different size-dependent structures.

PMID- 30275319 TI - How early media exposure may affect cognitive function: A review of results from observations in humans and experiments in mice. AB - Attention deficit hyperactivity disorder (ADHD) is now among the most commonly diagnosed chronic psychological dysfunctions of childhood. By varying estimates, it has increased by 30% in the past 20 years. Environmental factors that might explain this increase have been explored. One such factor may be audiovisual media exposure during early childhood. Observational studies in humans have linked exposure to fast-paced television in the first 3 years of life with subsequent attentional deficits in later childhood. Although longitudinal and well controlled, the observational nature of these studies precludes definitive conclusions regarding a causal relationship. As experimental studies in humans are neither ethical nor practical, mouse models of excessive sensory stimulation (ESS) during childhood, akin to the enrichment studies that have previously shown benefits of stimulation in rodents, have been developed. Experimental studies using this model have corroborated that ESS leads to cognitive and behavioral deficits, some of which may be potentially detrimental. Given the ubiquity of media during childhood, these findings in humansand rodents perhaps have important implications for public health. PMID- 30275322 TI - FtsZ filaments have the opposite kinetic polarity of microtubules. AB - FtsZ is the ancestral homolog of tubulin and assembles into the Z ring that organizes the division machinery to drive cell division in most bacteria. In contrast to tubulin that assembles into 13 stranded microtubules that undergo dynamic instability, FtsZ assembles into single-stranded filaments that treadmill to distribute the peptidoglycan synthetic machinery at the septum. Here, using longitudinal interface mutants of FtsZ, we demonstrate that the kinetic polarity of FtsZ filaments is opposite to that of microtubules. A conformational switch accompanying the assembly of FtsZ generates the kinetic polarity of FtsZ filaments, which explains the toxicity of interface mutants that function as a capper and reveals the mechanism of cooperative assembly. This approach can also be employed to determine the kinetic polarity of other filament-forming proteins. PMID- 30275323 TI - Drought losses in China might double between the 1.5 degrees C and 2.0 degrees C warming. AB - We project drought losses in China under global temperature increase of 1.5 degrees C and 2.0 degrees C, based on the Standardized Precipitation Evapotranspiration Index (SPEI) and the Palmer Drought Severity Index (PDSI), a cluster analysis method, and "intensity-loss rate" function. In contrast to earlier studies, to project the drought losses, we predict the regional gross domestic product under shared socioeconomic pathways instead of using a static socioeconomic scenario. We identify increasing precipitation and evapotranspiration pattern for the 1.5 degrees C and 2.0 degrees C global warming above the preindustrial at 2020-2039 and 2040-2059, respectively. With increasing drought intensity and areal coverage across China, drought losses will soar. The estimated loss in a sustainable development pathway at the 1.5 degrees C warming level increases 10-fold in comparison with the reference period 1986 2005 and nearly threefold relative to the interval 2006-2015. However, limiting the temperature increase to 1.5 degrees C can reduce the annual drought losses in China by several tens of billions of US dollars, compared with the 2.0 degrees C warming. PMID- 30275324 TI - Natural molecules induce and synergize to boost expression of the human antimicrobial peptide beta-defensin-3. AB - Antimicrobial peptides (AMPs) are mucosal defense effectors of the human innate immune response. In the intestine, AMPs are produced and secreted by epithelial cells to protect the host against pathogens and to support homeostasis with commensals. The inducible nature of AMPs suggests that potent inducers could be used to increase their endogenous expression for the prevention or treatment of diseases. Here we aimed at identifying molecules from the natural pharmacopoeia that induce expression of human beta-defensin-3 (HBD3), one of the most efficient AMPs, without modifying the production of proinflammatory cytokines. By screening, we identified three molecules isolated from medicinal plants, andrographolide, oridonin, and isoliquiritigenin, which induced HBD3 production in human colonic epithelial cells. This effect was observed without activation of the NF-kappaB pathway or the expression of associated proinflammatory cytokines. We identified the EGF receptor as the target of these compounds and characterized the downstream-activated MAPK pathways. At the chromatin level, molecules increased phosphorylation of histone H3 on serine S10 and recruitment of the c Fos, c-Jun, and Elk1 or c-Myc transcription factors at the HBD3 promoter. Interestingly, stimulating cells with a combination of andrographolide and isoliquiritigenin synergistically enhanced HBD3 induction 10-fold more than observed with each molecule alone. Finally, we investigated the molecular basis governing the synergistic effect, confirmed our findings in human colonic primary cells, and demonstrated that synergism increased cellular antimicrobial activity. This work shows the capability of small molecules to achieve induction of epithelial antimicrobial defenses while simultaneously avoiding the deleterious risks of an inflammatory response. PMID- 30275325 TI - Mercury isotope signatures record photic zone euxinia in the Mesoproterozoic ocean. AB - Photic zone euxinia (PZE) is a condition where anoxic, H2S-rich waters occur in the photic zone (PZ). PZE has been invoked as an impediment to the evolution of complex life on early Earth and as a kill mechanism for Phanerozoic mass extinctions. Here, we investigate the potential application of mercury (Hg) stable isotopes in marine sedimentary rocks as a proxy for PZE by measuring Hg isotope compositions in late Mesoproterozoic (~1.1 Ga) shales that have independent evidence of PZE during discrete intervals. Strikingly, a significantly negative shift of Hg mass-independent isotope fractionation (MIF) was observed during euxinic intervals, suggesting changes in Hg sources or transformations in oceans coincident with the development of PZE. We propose that the negative shift of Hg MIF was most likely caused by (i) photoreduction of Hg(II) complexed by reduced sulfur ligands in a sulfide-rich PZ, and (ii) enhanced sequestration of atmospheric Hg(0) to the sediments by thiols and sulfide that were enriched in the surface ocean as a result of PZE. This study thus demonstrates that Hg isotope compositions in ancient marine sedimentary rocks can be a promising proxy for PZE and therefore may provide valuable insights into changes in ocean chemistry and its impact on the evolution of life. PMID- 30275326 TI - Cytoprotective metal-organic frameworks for anaerobic bacteria. AB - We report a strategy to uniformly wrap Morella thermoacetica bacteria with a metal-organic framework (MOF) monolayer of nanometer thickness for cytoprotection in artificial photosynthesis. The catalytic activity of the MOF enclosure toward decomposition of reactive oxygen species (ROS) reduces the death of strictly anaerobic bacteria by fivefold in the presence of 21% O2, and enables the cytoprotected bacteria to continuously produce acetate from CO2 fixation under oxidative stress. The high definition of the MOF-bacteria interface involving direct bonding between phosphate units on the cell surface and zirconium clusters on MOF monolayer, provides for enhancement of life throughout reproduction. The dynamic nature of the MOF wrapping allows for cell elongation and separation, including spontaneous covering of the newly grown cell surface. The open-metal sites on the zirconium clusters lead to 600 times more efficient ROS decomposition compared with zirconia nanoparticles. PMID- 30275327 TI - HEIP1 regulates crossover formation during meiosis in rice. AB - During meiosis, the number of double-strand breaks (DSBs) far exceeds the final number of crossovers (COs). Therefore, to identify proteins involved in determining which of these DSBs repaired into COs is critical in understanding the mechanism of CO control. Across species, HEI10-related proteins play important roles in CO formation. Here, through screening for HEI10-interacting proteins via a yeast two-hybrid system, we identify a CO protein HEI10 Interaction Protein 1 (HEIP1) in rice. HEIP1 colocalizes with HEI10 in a dynamic fashion along the meiotic chromosomes and specially localizes onto crossover sites from late pachytene to diplotene. Between these two proteins, HEI10 is required for the loading of HEIP1, but not vice versa. Moreover, mutations of the HEIP1 gene cause the severe reduction of chiasma frequency, whereas early homologous recombination processes are not disturbed and synapsis proceeds normally. HEIP1 interacts directly with ZIP4 and MSH5. In addition, the loading of HEIP1 depends on ZIP4, but not on MER3, MSH4, or MSH5. Together, our results suggest that HEIP1 may be a member of the ZMM group and acts as a key element regulating CO formation. PMID- 30275328 TI - Viable cyanobacteria in the deep continental subsurface. AB - Cyanobacteria are ecologically versatile microorganisms inhabiting most environments, ranging from marine systems to arid deserts. Although they possess several pathways for light-independent energy generation, until now their ecological range appeared to be restricted to environments with at least occasional exposure to sunlight. Here we present molecular, microscopic, and metagenomic evidence that cyanobacteria predominate in deep subsurface rock samples from the Iberian Pyrite Belt Mars analog (southwestern Spain). Metagenomics showed the potential for a hydrogen-based lithoautotrophic cyanobacterial metabolism. Collectively, our results suggest that they may play an important role as primary producers within the deep-Earth biosphere. Our description of this previously unknown ecological niche for cyanobacteria paves the way for models on their origin and evolution, as well as on their potential presence in current or primitive biospheres in other planetary bodies, and on the extant, primitive, and putative extraterrestrial biospheres. PMID- 30275329 TI - Proinsulin C-peptide is an autoantigen in people with type 1 diabetes. AB - Type 1 diabetes (T1D) is an autoimmune disease in which insulin-producing beta cells, found within the islets of Langerhans in the pancreas, are destroyed by islet-infiltrating T cells. Identifying the antigenic targets of beta-cell reactive T cells is critical to gain insight into the pathogenesis of T1D and develop antigen-specific immunotherapies. Several lines of evidence indicate that insulin is an important target of T cells in T1D. Because many human islet infiltrating CD4+ T cells recognize C-peptide-derived epitopes, we hypothesized that full-length C-peptide (PI33-63), the peptide excised from proinsulin as it is converted to insulin, is a target of CD4+ T cells in people with T1D. CD4+ T cell responses to full-length C-peptide were detected in the blood of: 14 of 23 (>60%) people with recent-onset T1D, 2 of 15 (>13%) people with long-standing T1D, and 1 of 13 (<8%) HLA-matched people without T1D. C-peptide-specific CD4+ T cell clones, isolated from six people with T1D, recognized epitopes from the entire 31 amino acids of C-peptide. Eighty-six percent (19 of 22) of the C peptide-specific clones were restricted by HLA-DQ8, HLA-DQ2, HLA-DQ8trans, or HLA DQ2trans, HLA alleles strongly associated with risk of T1D. We also found that full-length C-peptide was a much more potent agonist of some CD4+ T cell clones than an 18mer peptide encompassing the cognate epitope. Collectively, our findings indicate that proinsulin C-peptide is a key target of autoreactive CD4+ T cells in T1D. Hence, full-length C-peptide is a promising candidate for antigen specific immunotherapy in T1D. PMID- 30275330 TI - Allosteric potentiation of a ligand-gated ion channel is mediated by access to a deep membrane-facing cavity. AB - Theories of general anesthesia have shifted in focus from bulk lipid effects to specific interactions with membrane proteins. Target receptors include several subtypes of pentameric ligand-gated ion channels; however, structures of physiologically relevant proteins in this family have yet to define anesthetic binding at high resolution. Recent cocrystal structures of the bacterial protein GLIC provide snapshots of state-dependent binding sites for the common surgical agent propofol (PFL), offering a detailed model system for anesthetic modulation. Here, we combine molecular dynamics and oocyte electrophysiology to reveal differential motion and modulation upon modification of a transmembrane binding site within each GLIC subunit. WT channels exhibited net inhibition by PFL, and a contraction of the cavity away from the pore-lining M2 helix in the absence of drug. Conversely, in GLIC variants exhibiting net PFL potentiation, the cavity was persistently expanded and proximal to M2. Mutations designed to favor this deepened site enabled sensitivity even to subclinical concentrations of PFL, and a uniquely prolonged mode of potentiation evident up to ~30 min after washout. Dependence of these prolonged effects on exposure time implicated the membrane as a reservoir for a lipid-accessible binding site. However, at the highest measured concentrations, potentiation appeared to be masked by an acute inhibitory effect, consistent with the presence of a discrete, water-accessible site of inhibition. These results support a multisite model of transmembrane allosteric modulation, including a possible link between lipid- and receptor-based theories that could inform the development of new anesthetics. PMID- 30275331 TI - Adult spinal motoneurons change their neurotransmitter phenotype to control locomotion. AB - A particularly essential determinant of a neuron's functionality is its neurotransmitter phenotype. While the prevailing view is that neurotransmitter phenotypes are fixed and determined early during development, a growing body of evidence suggests that neurons retain the ability to switch between different neurotransmitters. However, such changes are considered unlikely in motoneurons due to their crucial functional role in animals' behavior. Here we describe the expression and dynamics of glutamatergic neurotransmission in the adult zebrafish spinal motoneuron circuit assembly. We demonstrate that part of the fast motoneurons retain the ability to switch their neurotransmitter phenotype under physiological (exercise/training) and pathophysiological (spinal cord injury) conditions to corelease glutamate in the neuromuscular junctions to enhance animals' motor output. Our findings suggest that motoneuron neurotransmitter switching is an important plasticity-bestowing mechanism in the reconfiguration of spinal circuits that control movements.

PMID- 30275334 TI - Rapid diversification of Pseudomonas aeruginosa in cystic fibrosis lung-like conditions. AB - Chronic infection of the cystic fibrosis (CF) airway by the opportunistic pathogen Pseudomonas aeruginosa is the leading cause of morbidity and mortality for adult CF patients. Prolonged infections are accompanied by adaptation of P. aeruginosa to the unique conditions of the CF lung environment, as well as marked diversification of the pathogen into phenotypically and genetically distinct strains that can coexist for years within a patient. Little is known, however, about the causes of this diversification and its impact on patient health. Here, we show experimentally that, consistent with ecological theory of diversification, the nutritional conditions of the CF airway can cause rapid and extensive diversification of P. aeruginosa Mucin, the substance responsible for the increased viscosity associated with the thick mucus layer in the CF airway, had little impact on within-population diversification but did promote divergence among populations. Furthermore, in vitro evolution recapitulated traits thought to be hallmarks of chronic infection, including reduced motility and increased biofilm formation, and the range of phenotypes observed in a collection of clinical isolates. Our results suggest that nutritional complexity and reduced dispersal can drive evolutionary diversification of P. aeruginosa independent of other features of the CF lung such as an active immune system or the presence of competing microbial species. We suggest that diversification, by generating extensive phenotypic and genetic variation on which selection can act, may be a key first step in the development of chronic infections. PMID- 30275335 TI - Coordination of cell migration mediated by site-dependent cell-cell contact. AB - Contact inhibition of locomotion (CIL), the repulsive response of cells upon cell cell contact, has been the predominant paradigm for contact-mediated responses. However, it is difficult for CIL alone to account for the complex behavior of cells within a multicellular environment, where cells often migrate in cohorts such as sheets, clusters, and streams. Although cell-cell adhesion and mechanical interactions play a role, how individual cells coordinate their migration within a multicellular environment remains unclear. Using micropatterned substrates to guide cell migration and manipulate cell-cell contact, we show that contacts between different regions of cells elicit different responses. Repulsive responses were limited to interaction with the head of a migrating cell, while contact with the tail of a neighboring cell promoted migration toward the tail. The latter behavior, termed contact following of locomotion (CFL), required the Wnt signaling pathway. Inhibition of the Wnt pathway disrupted not only CFL but also collective migration of epithelial cells, without affecting the migration of individual cells. In contrast, inhibition of myosin II with blebbistatin disrupted the migration of both individual epithelial cells and collectives. We propose that CFL, in conjunction with CIL, plays a major role in guiding and coordinating cell migration within a multicellular environment.

PMID- 30275337 TI - Serotonin signaling regulates insulin-like peptides for growth, reproduction, and metabolism in the disease vector Aedes aegypti. AB - Disease-transmitting female mosquitoes require a vertebrate blood meal to produce their eggs. An obligatory hematophagous lifestyle, rapid reproduction, and existence of a large number of transmittable diseases make mosquitoes the world's deadliest animals. Attaining optimal body size and nutritional status is critical for mosquitoes to become reproductively competent and effective disease vectors. We report that blood feeding boosts serotonin concentration and elevates the serotonin receptor Aa5HT2B (Aedes aegypti 5-hydroxytryptamine receptor, type 2B) transcript level in the fat-body, an insect analog of the vertebrate liver and adipose tissue. Aa5HT2B gene disruption using the CRISPR-Cas9 gene-editing approach led to a decreased body size, postponed development, shortened lifespan, retarded ovarian growth, and dramatically diminished lipid accumulation. Expression of the insulin-like peptide (ILP) genes ilp2 and ilp6 was down regulated while that of ilp5 and ilp4 was up-regulated in response to Aa5HT2B disruption. CRISPR-Cas9 disruption of ilp2 or ilp6 resulted in adverse phenotypes similar to those of Aa5HT2B disruption, while ilp5 CRISPR-Cas9 disruption had exactly the opposite effect on growth and metabolism, with significantly increased body size and elevated lipid stores. Simultaneous CRISPR-Cas9 disruption of Aa5HT2B and ilp5 rescued these phenotypic manifestations. Aa5HT2B RNAi silencing rendered ilp6 insensitive to serotonin treatment in the cultured fat-body, suggesting a regulatory link between Aa5HT2B and ILP6. Moreover, CRISPR Cas9 ilp6 disruption affects expression of ilp-2, -5, and -4, pointing out on a possible role of ILP6 as a mediator of the Aa5HT2B action. PMID- 30275338 TI - Active apolar doping determines routes to colloidal clusters and gels. AB - Collections of interacting active particles, self-propelling or not, have shown remarkable phenomena including the emergence of dynamic patterns across different length scales, from animal groups to vibrated grains, microtubules, bacteria, and chemical- or field-driven colloids. Burgeoning experimental and simulation activities are now exploring the possibility of realizing solid and stable structures from passive elements that are assembled by a few active dopants. Here we show that such an elusive task may be accomplished by using a small amount of apolar dopants, namely synthetic active but not self-propelling units. We use blue light to rapidly assemble 2D colloidal clusters and gels via nonequilibrium diffusiophoresis, where microscopic hematite dockers form long-living interstitial bonds that strongly glue passive silica microspheres. By varying the relative fraction of doping, we uncover a rich phase diagram including ordered and disordered clusters, space-filling gels, and bicontinuous structures formed by filamentary dockers percolating through a solid network of silica spheres. We characterize the slow relaxation and dynamic arrest of the different phases via correlation and scattering functions. Our findings provide a pathway toward the rapid engineering of mesoscopic gels and clusters via active colloidal doping.

PMID- 30275336 TI - High-throughput in vivo screen of functional mRNA delivery identifies nanoparticles for endothelial cell gene editing. AB - Dysfunctional endothelium causes more disease than any other cell type. Systemically administered RNA delivery to nonliver tissues remains challenging, in large part because there is no high-throughput method to identify nanoparticles that deliver functional mRNA to cells in vivo. Here we report a system capable of simultaneously quantifying how >100 lipid nanoparticles (LNPs) deliver mRNA that is translated into functional protein. Using this system (named FIND), we measured how >250 LNPs delivered mRNA to multiple cell types in vivo and identified 7C2 and 7C3, two LNPs that efficiently deliver siRNA, single-guide RNA (sgRNA), and mRNA to endothelial cells. The 7C3 delivered Cas9 mRNA and sgRNA to splenic endothelial cells as efficiently as hepatocytes, distinguishing it from LNPs that deliver Cas9 mRNA and sgRNA to hepatocytes more than other cell types. These data demonstrate that FIND can identify nanoparticles with novel tropisms in vivo.

AB - The development and maintenance of multicellular organisms require specialized coordination between external cellular signals and the proteins receiving stimuli and regulating responses. A critical role in the proper functioning of these processes is played by endosomal trafficking, which enables the transport of proteins to targeted sites as well as their return to the plasma membrane through its essential components, the endosomes. During this trafficking, signaling pathways controlling functions related to the endosomal system are activated both directly and indirectly. Although there are a considerable number of molecules participating in these processes, some are more known than others for their specific functions. Toward the end of the 1990s, Smad anchor for receptor activation (SARA) protein was described to be controlling and to facilitate the localization of Smads to transforming growth factor beta (TGF-beta) receptors during TGF-beta signaling activation, and, strikingly, SARA was also identified to be one of the proteins that bind to early endosomes (EEs) participating in membrane trafficking in several cell models. The purpose of this review is to analyze the state of the art of the contribution of SARA in different cell types and cellular contexts, focusing on the biological role of SARA in two main processes, trafficking and cellular signaling, both of which are necessary for intercellular coordination, communication, and development. PMID- 30275344 TI - Mediator Is Essential for Small Nuclear and Nucleolar RNA Transcription in Yeast. AB - Eukaryotic RNA polymerase II (RNAPII) transcribes mRNA genes and non-protein coding RNA (ncRNA) genes, including those encoding small nuclear and nucleolar RNAs (sn/snoRNAs). In metazoans, RNAPII transcription of sn/snoRNAs is facilitated by a number of specialized complexes, but no such complexes have been discovered in yeast. It has been proposed that yeast sn/snoRNA and mRNA expression relies on a set of common factors, but the extent to which regulators of mRNA genes function at yeast sn/snoRNA genes is unclear. Here, we investigated a potential role for the Mediator complex, essential for mRNA gene transcription, in sn/snoRNA gene transcription. We found that Mediator maps to sn/snoRNA gene regulatory regions and that rapid depletion of the essential structural subunit Med14 strongly reduces RNAPII and TFIIB occupancy as well as nascent transcription of sn/snoRNA genes. Deletion of Med3 and Med15, subunits of the activator-interacting Mediator tail module, does not affect Mediator recruitment to or RNAPII and TFIIB occupancy of sn/snoRNA genes. Our analyses suggest that Mediator promotes PIC formation and transcription at sn/snoRNA genes, expanding the role of this critical regulator beyond its known functions in mRNA gene transcription and demonstrating further mechanistic similarity between the transcription of mRNA and sn/snoRNA genes. PMID- 30275346 TI - Haemogregarine (Apicomplexa: Adeleorina) infection in Vanderhaege's toad-headed turtle, Mesoclemmys vanderhaegei (Chelidae), from a Brazilian Neotropical savanna region. AB - Knowledge of blood parasites in Brazilian chelonians is limited, since they have been recorded in only six species. Mesoclemmys vanderhaegei (Bour) is a freshwater turtle with a wide geographic distribution in Brazil, but there is little information about its natural history. This paper reports on a study of the prevalence and infection intensity of a haemogregarine in two subpopulations of M. vanderhaegei. The study was conducted in two areas of Cerrado in the Upper Paraguay River basin in the state of Mato Grosso, Brazil, between November 2010 and August 2013. Ninety-five (53%) of the 179 turtles captured were positive for haemogregarine parasites. The parasitic forms observed were two morphotypes of intraerythrocytic gametocytes. The prevalence differed between size classes, increasing significantly according to the animals' body size. There was no significant difference between prevalence and sex, or between sampling periods. The mean parasite intensity was 9 parasites/2,000 erythrocytes (0.45%) and the parasite population presented an aggregated distribution, with an aggregation index of 19 and discrepancy of 0.772. This is the first record of a hemoparasite in the freshwater turtle M. vanderhaegei.

AB - The regenerative process of injured muscle is dependent on the fusion and differentiation of myoblasts derived from muscle stem cells. Hsp70 is important for maintaining skeletal muscle homeostasis and regeneration, but the precise cellular mechanism remains elusive. In this study, we found that Hsp70 was upregulated during myoblast differentiation. Depletion or inhibition of Hsp70/Hsc70 impaired myoblast differentiation. Importantly, overexpression of p38 mitogen-activated protein kinase alpha (p38MAPKalpha) but not AKT1 rescued the impairment of myogenic differentiation in Hsp70- or Hsc70-depleted myoblasts. Moreover, Hsp70 interacted with MK2, a substrate of p38MAPK, to regulate the stability of p38MAPK. Knockdown of Hsp70 also led to downregulation of both MK2 and p38MAPK in intact muscles and during cardiotoxin-induced muscle regeneration. Hsp70 bound MK2 to regulate MK2-p38MAPK interaction in myoblasts. We subsequently identified the essential regions required for Hsp70-MK2 interaction. Functional analyses showed that MK2 is essential for both myoblast differentiation and skeletal muscle regeneration. Taken together, our findings reveal a novel role of Hsp70 in regulating myoblast differentiation by interacting with MK2 to stabilize p38MAPK. PMID- 30275347 TI - Enhanced Upconversion and Downshifting emissions from Tb3+, Yb3+ co-doped CaZrO3 phosphor in presence of Li+ ions. AB - This paper reports the enhanced green photoluminescence from Tb3+, Yb3+ co-doped CaZrO3 phosphor in the presence of Li+ ion synthesized through solid state reaction technique. The structural studies show an increase in the particle size and a shrink in crystal lattice due to Li+ co-doping in the phosphor. The phosphor sample emits intense green upconversion emission (UC) due to Tb3+ ions on excitation with 980 nm radiation which is further enhanced ~ 28 times on Li+ co-doping. The lifetime of 5D4 level of Tb3+ ion decreases in the presence of Li+ ions due to increase in asymmetry in crystal field. The downshifting (DS) emission intensity monitored on 378 and 487nm excitations is also enhanced in the presence of Li+ ions. Thus, the Tb3+, Yb3+, Li+ co-doped CaZrO3 phosphor can be a suitable candidate for UC solid state lighting. PMID- 30275348 TI - Anodic Stimulation Misunderstood: Preferential Activation of Fiber Orientations with Anodic Waveforms in Deep Brain Stimulation. AB - OBJECTIVE: During deep brain stimulation (DBS), it is well understood that extracellular cathodic stimulation can cause activation of passing axons. Activation can be predicted from the second derivative of the electric potential along an axon, which depends on axonal orientation with respect to the stimulation source. We hypothesize that fiber orientation influences activation thresholds and that fiber orientations can be selectively targeted with DBS waveforms. Approach: We used bioelectric field and multicompartment NEURON models to explore preferential activation based on fiber orientation during monopolar or bipolar stimulation. Preferential fiber orientation was extracted from the principal eigenvectors and eigenvalues of the Hessian matrix of the electric potential. We tested cathodic, anodic, and charge-balanced pulses to target neurons based on fiber orientation in general and clinical scenarios. Main Results: Axons passing the DBS lead have positive second derivatives around a cathode, whereas orthogonal axons have positive second derivatives around an anode, as indicated by the Hessian. Multicompartment NEURON models confirm that passing fibers are activated by cathodic stimulation, and orthogonal fibers are activated by anodic stimulation. Additionally, orthogonal axons have lower thresholds compared to passing axons. In a clinical scenario, fiber pathways associated with therapeutic benefit can be targeted with anodic stimulation at 50% lower stimulation amplitudes. Significance: Fiber orientations can be selectively targeted with simple changes to the stimulus waveform. Anodic stimulation preferentially activates orthogonal fibers, approaching or leaving the electrode, at lower thresholds for similar therapeutic benefit in DBS with decreased power consumption. PMID- 30275349 TI - Combination Therapy for Reconstructive Periodontal Treatment in the Lower Anterior Area: Clinical Evaluation of a Case Series. AB - Clinically, periodontal regeneration may be achieved by the application of barrier membranes, grafts, wound-healing modifiers, and their combinations. Combination therapy refers to the simultaneous application of various periodontal reconstructive treatment alternatives to obtain additive effects. This approach may lead to assemblage of different regenerative principles, such as conductivity and inductivity, space provision and wound stability, matrix development and cell differentiation. The application of autogenous connective tissue grafts during periodontal regenerative treatment with enamel matrix proteins derivative (EMD) has been previously reported. The present case series present a modified approach for treatment of severe periodontally involved lower incisors presenting with thin gingival biotype, gingival recession, minimal attached and keratinized gingiva width and muscle and/or frenum pull. In all cases a combination therapy consisting of a single buccal access flap, root conditioning, EMD application on the denuded root surfaces and a free connective tissue graft was performed. Clinical and radiographic outcomes were consistently satisfactory, leading to probing depth reduction, clinical attachment gain, minimal gingival recession, increased attached and keratinizing gingival width, elimination of frenum and/or muscle pull together with radiographic bone fill of the defects. It may be concluded that the present combination therapy for reconstructive periodontal treatment in the lower anterior area is a valuable alternative for indicated cases.

AB - A TiB/Ti-6Al-4V composite reinforced with ultra-fine TiB whiskers (UF-TiB) was prepared by the powder metallurgy method. High temperature compression tests were carried out to study the hot deformation behavior of the UF-TiB/Ti-6Al-4V composite. The compressive deformation was performed in the temperature range of 900-1200 degrees C and the strain rate range of 0.001-10 s-1. The results showed that stable flow occurred at the condition of 900-1200 degrees C/0.001-0.01 s-1. The optimum working condition was 900 degrees C/0.001 s-1, with the deformation mechanism of dynamic recrystallization (DRX). Instable flow occurred when the strain rate was higher than 0.01 s-1, where the failure modes included adiabatic shear deformation, whisker breakage and whisker/matrix debonding. The deformability of the UF-TiB/Ti-6Al-4V composite was much better than the traditional casted and the pressed + sintered TiB/Ti-6Al-4V composites, which are typically reinforced with coarse-grained TiB whiskers. The high deformability was primarily attributed to the ultra-fine reinforcements, which could coordinate the deformation more effectively. In addition, a fine matrix microstructure also had a positive effect on deformability because the fine matrix microstructure could improve the grain boundary sliding.

AB - The present study investigated high-aspect ratio micro-hole array parts which were made by ZrO2 micro-powder with different particle sizes and micro-powder injection molding technology. It analysed the influence of particle sizes on feedstock, debinding and sintering of ceramic nozzles with multi-micro-holes. The forming quality of ceramic nozzles with multi-micro-holes was discussed in this paper. The results show that the two mixed ZrO2 feedstocks have fine uniformity. The average deviation of the feedstock made with 200 nm powder was -2%, and the average deviation of the feedstock made with 100 nm powder was -7.1%. The sample showed certain sintering characteristics which provided better strength (11.10 MPa) to parts after debinding. The linear shrinkage and the density of the two powder samples at different sintering temperatures increased as the sintering temperature increased. If the temperature continued to increase, the linear shrinkage and the density decreased. The highest hardness and flexural strength values of the ZrO2 sample with 200 nm powder used were: 1265.5 HV and 453.4 MPa, and the crystalline particle size was 0.36 MUm. The highest hardness and flexural strength values of the ZrO2 sample with 100 nm powder used were: 1425.8 HV and 503.6 MPa, and the crystalline particle size was 0.18 MUm. The ceramic nozzles with multi-micro holes shrunk to nearly the same axial, radial and circumferential directions during sintering. After sintering, the roundness of ceramic micro-hole met the user requirements, and the circular hole had a high parallelism in the axial direction. The micropore diameter was 450 +/- 5 MUm, and it was possible to control the dimensional accuracy within 1.5% after sintering. The study presented a superior application prospect for high-aspect ratio micro hole array parts in aerospace, electronics and biomedicine.

AB - Wine grape pomace flour (WGPF) is a fruit byproduct that is high in fiber and antioxidants. We tested whether WGPF consumption could affect blood biochemical parameters, including oxidative stress biomarkers. In a three-month intervention study, 27 male volunteers, each with some components of metabolic syndrome, consumed a beef burger supplemented with 7% WGPF containing 3.5% of fiber and 1.2 mg gallic equivalents (GE)/g of polyphenols (WGPF-burger), daily, during the first month. The volunteers consumed no burgers in the second month, and one control-burger daily in the third month. At baseline and after these periods, we evaluated the metabolic syndrome components, plasma antioxidant status (i.e., 2,2 diphenyl-1-picrylhydrazyl radical scavenging capacity (DPPH), vitamin E, vitamin C), and oxidative damage markers (i.e., advanced oxidation protein products (AOPPs), oxidized low-density lipoproteins (oxLDLs), malondialdehyde (MDA)). The WGPF-burger intake significantly reduced glycemia and homeostatic model assessment-based measurement of insulin resistance. Vitamin C increased and decreased during the consumption of the WGPF-burger and control-burger, respectively. The WGPF-burger intake significantly decreased AOPP and oxLDL levels. Vitamin E and MDA levels showed no significant changes. In conclusion, the consumption of beef burgers prepared with WGPF improved fasting glucose and insulin resistance, plasma antioxidant levels, and oxidative damage markers. Therefore, this functional ingredient has potential as a dietary supplement to manage chronic disease risk in humans.

AB - By treating with histone-deacetylase inhibitor valproate sodium, three new heterdimeric tetrahydroxanthone-chromanone lactones chrysoxanthones A-C (1-3), along with 17 known compounds were isolated from a sponge-associated Penicillium chrysogenum HLS111. The planar structures of chrysoxanthones A-C were elucidated by means of spectroscopic analyses, including MS, 1D, and 2D NMR. Their absolute configurations were established by electronic circular dichroism (ECD) calculations. Chrysoxanthones A-C exhibited moderate antibacterial activities against Bacillus subtilis with minimum inhibitory concentration (MIC) values of 5 10 MUg/mL. PMID- 30275355 TI - A Novel Cold-Adapted Leucine Dehydrogenase from Antarctic Sea-Ice Bacterium Pseudoalteromonas sp. ANT178. AB - l-tert-leucine and its derivatives are useful as pharmaceutical active ingredients, in which leucine dehydrogenase (LeuDH) is the key enzyme in their enzymatic conversions. In the present study, a novel cold-adapted LeuDH, psleudh, was cloned from psychrotrophic bacteria Pseudoalteromonas sp. ANT178, which was isolated from Antarctic sea-ice. Bioinformatics analysis of the gene psleudh showed that the gene was 1209 bp in length and coded for a 42.6 kDa protein containing 402 amino acids. PsLeuDH had conserved Phe binding site and NAD+ binding site, and belonged to a member of the Glu/Leu/Phe/Val dehydrogenase family. Homology modeling analysis results suggested that PsLeuDH exhibited more glycine residues, reduced proline residues, and arginine residues, which might be responsible for its catalytic efficiency at low temperature. The recombinant PsLeuDH (rPsLeuDH) was purified a major band with the high specific activity of 275.13 U/mg using a Ni-NTA affinity chromatography. The optimum temperature and pH for rPsLeuDH activity were 30 degrees C and pH 9.0, respectively. Importantly, rPsLeuDH retained at least 40% of its maximum activity even at 0 degrees C. Moreover, the activity of rPsLeuDH was the highest in the presence of 2.0 M NaCl. Substrate specificity and kinetic studies of rPsLeuDH demonstrated that l-leucine was the most suitable substrate, and the catalytic activity at low temperatures was ensured by maintaining a high kcat value. The results of the current study would provide insight into Antarctic sea-ice bacterium LeuDH, and the unique properties of rPsLeuDH make it a promising candidate as a biocatalyst in medical and pharmaceutical industries.

(Asteraceae) refers to several species of plants used in traditional phytotherapeutic preparations. B. tripartita, also known as bur marigold, is the most familiar plant and has been known as a remedy for chronic dysentery. The hydrodistilled essential oil of the aerial parts of the Polish B. tripartita was analyzed using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) techniques. To exclude any potential toxic effects of the oil on human dermal fibroblasts, the MTT test (methyl thiazolyl tetrazolium) and COMET assay (single-cell gel electrophoresis) were performed. Novel gel formulations as topical carriers for essential oil obtained from B. tripartita were developed and characterized. The bioadhesive properties of the designed preparations in the ex vivo model using the skin of hairless mice were also evaluated. The therapeutic efficacy of the topical formulations is influenced by active phytoconstituents and vehicle characteristics. The antifungal properties of the essential oil of B. tripartita were also tested against Candida species, and this oil appears to be a promising topical anticandidal agent. PMID- 30275357 TI - Molecular Lesions of Insulator CTCF and Its Paralogue CTCFL (BORIS) in Cancer: An Analysis from Published Genomic Studies. AB - CTCF (CCCTC-binding factor) is a transcription regulator with hundreds of binding sites in the human genome. It has a main function as an insulator protein, defining together with cohesins the boundaries of areas of the genome called topologically associating domains (TADs). TADs contain regulatory elements such as enhancers which function as regulators of the transcription of genes inside the boundaries of the TAD while they are restricted from regulating genes outside these boundaries. This paper will examine the most common genetic lesions of CTCF as well as its related protein CTCFL (CTCF-like also called BORIS) in cancer using publicly available data from published genomic studies. Cancer types where abnormalities in the two genes are more common will be examined for possible associations with underlying repair defects or other prevalent genetic lesions. The putative functional effects in CTCF and CTCFL lesions will also be explored. PMID- 30275356 TI - Effect of Branched-Chain Amino Acid Supplementation on Recovery Following Acute Eccentric Exercise. AB - This study investigated the effect of branched-chain amino acid (BCAA) supplementation on recovery from eccentric exercise. Twenty males ingested either a BCAA supplement or placebo (PLCB) prior to and following eccentric exercise. Creatine kinase (CK), vertical jump (VJ), maximal voluntary isometric contraction (MVIC), jump squat (JS) and perceived soreness were assessed. No significant (p > 0.05) group by time interaction effects were observed for CK, soreness, MVIC, VJ, or JS. CK concentrations were elevated above baseline (p < 0.001) in both groups at 4, 24, 48 and 72 hr, while CK was lower (p = 0.02) in the BCAA group at 48 hr compared to PLCB. Soreness increased significantly from baseline (p < 0.01) in both groups at all time-points; however, BCAA supplemented individuals reported less soreness (p < 0.01) at the 48 and 72 hr time-points. MVIC force output returned to baseline levels (p > 0.05) at 24, 48 and 72 hr for BCAA individuals. No significant difference between groups (p > 0.05) was detected for VJ or JS. BCAA supplementation may mitigate muscle soreness following muscle-damaging exercise. However, when consumed with a diet consisting of ~1.2 g/kg/day protein, the attenuation of muscular performance decrements or corresponding plasma CK levels are likely negligible. PMID- 30275358 TI - Detailed Modeling of the Direct Reduction of Iron Ore in a Shaft Furnace. AB - This paper addresses the modeling of the iron ore direct reduction process, a process likely to reduce CO2 emissions from the steel industry. The shaft furnace is divided into three sections (reduction, transition, and cooling), and the model is two-dimensional (cylindrical geometry for the upper sections and conical geometry for the lower one), to correctly describe the lateral gas feed and cooling gas outlet. This model relies on a detailed description of the main physical-chemical and thermal phenomena, using a multi-scale approach. The moving bed is assumed to be comprised of pellets of grains and crystallites. We also take into account eight heterogeneous and two homogeneous chemical reactions. The local mass, energy, and momentum balances are numerically solved, using the finite volume method. This model was successfully validated by simulating the shaft furnaces of two direct reduction plants of different capacities. The calculated results reveal the detailed interior behavior of the shaft furnace operation. Eight different zones can be distinguished, according to their predominant thermal and reaction characteristics. An important finding is the presence of a central zone of lesser temperature and conversion. PMID- 30275360 TI - A Customer Feedback Platform for Vehicle Manufacturing Compliant with Industry 4.0 Vision. AB - In the last decade, the growth of the automotive market with the aid of technologies has been notable for the economic, automotive and technological sectors. Alongside this growing recognition, the so called Internet of Intelligent Vehicles (IoIV) emerges as an evolution of the Internet of Things (IoT) applied to the automotive sector. Closely related to IoIV, emerges the concept of Industrial Internet of Things (IIoT), which is the current revolution seen in industrial automation. IIoT, in its turn, relates to the concept of Industry 4.0, that is used to represent the current Industrial Revolution. This revolution, however, involves different areas: from manufacturing to healthcare. The Industry 4.0 can create value during the entire product lifecycle, promoting customer feedback, that is, having information about the product history throughout it is life. In this way, the automatic communication between vehicle and factory was facilitated, allowing the accomplishment of different analysis regarding vehicles, such as the identification of a behavioral pattern through historical driver usage, fuel consumption, maintenance indicators, so on. Thus, allowing the prevention of critical issues and undesired behaviors, since the automakers lose contact with the vehicle after the purchase. Therefore, this paper aims to propose a customer feedback platform for vehicle manufacturing in Industry 4.0 context, capable of collecting and analyzing, through an OBD-II (On Board Diagnostics) scanner, the sensors available by vehicles, with the purpose of assisting in the management, prevention, and mitigation of different vehicular problems. An intercontinental evaluation conducted between Brazil and Italy locations shown the feasibility of platform and the potential to use in order to improve the vehicle manufacturing process. PMID- 30275359 TI - The Role of Physical Stimuli on Calcium Channels in Chondrogenic Differentiation of Mesenchymal Stem Cells. AB - Human mesenchymal stem cells (hMSC) are becoming increasingly popular in tissue engineering. They are the most frequently used stem cell source for clinical applications due to their high potential to differentiate into several lineages. Cartilage is known for its low capacity for self-maintenance and currently there are no efficient methods to improve cartilage repair. Chondrogenic differentiation of hMSC isolated from different tissues is widely employed due to a high clinical demand for the improvement of cartilage regeneration. Calcium channels that are regulated by physical stimuli seem to play a pivotal role in chondrogenic differentiation of MSCs. These channels increase intracellular calcium concentration, which leads to the initiation of the relevant cellular processes that are required for differentiation. This review will focus on the impact of different physical stimuli, including electrical, electromagnetic/magnetic and mechanical on various calcium channels and calcium signaling mechanisms during chondrogenic differentiation of hMSC. PMID- 30275361 TI - Local Deformation and Texture of Cold-Rolled AA6061 Aluminum Alloy. AB - Using cold rolling, we plastically deform AA6061 sheets at room temperature and investigate the variations of the microstructures, textures and local deformation of the cold-rolled AA6061 sheets as functions of thickness reduction (Deltat/t0, t0 and t are the thicknesses of the AA6061 sheet before and after the cold rolling, respectively). The volume fraction of total deformation texture is relatively independent of the thickness reduction for Deltat/t0 <= 30%, and becomes an approximately linearly increasing function of the thickness reduction for Deltat/t0 > 30%. Increasing the thickness reduction causes the increase of the Vickers hardness of the cross-section of the cold-rolled sheets, which exhibits a similar increase trend to the volume fraction of total deformation texture for Deltat/t0 > 30%. A simple relation between the Vickers hardness and the thickness reduction is established and is used to curve-fit the experimental results. PMID- 30275362 TI - Molecular Mechanisms of the Methionine Sulfoxide Reductase System from Neisseria meningitidis. AB - Neisseria meningitidis, an obligate pathogenic bacterium in humans, has acquired different defense mechanisms to detect and fight the oxidative stress generated by the host's defense during infection. A notable example of such a mechanism is the PilB reducing system, which repairs oxidatively-damaged methionine residues. This review will focus on the catalytic mechanism of the two methionine sulfoxide reductase (MSR) domains of PilB, which represent model enzymes for catalysis of the reduction of a sulfoxide function by thiols through sulfenic acid chemistry. The mechanism of recycling of these MSR domains by various "Trx-like" disulfide oxidoreductases will also be discussed. PMID- 30275363 TI - Ferroportin-Hepcidin Axis in Prepubertal Obese Children with Sufficient Daily Iron Intake. AB - Iron metabolism may be disrupted in obesity, therefore, the present study assessed the iron status, especially ferroportin and hepcidin concentrations, as well as associations between the ferroportin-hepcidin axis and other iron markers in prepubertal obese children. The following were determined: serum ferroportin, hepcidin, ferritin, soluble transferrin receptor (sTfR), iron concentrations and values of hematological parameters as well as the daily dietary intake in 40 obese and 40 normal-weight children. The ferroportin/hepcidin and ferritin/hepcidin ratios were almost two-fold lower in obese children (p = 0.001; p = 0.026, respectively). Similar iron concentrations (13.2 vs. 15.2 umol/L, p = 0.324), the sTfR/ferritin index (0.033 vs. 0.041, p = 0.384) and values of hematological parameters were found in obese and control groups, respectively. Iron daily intake in the obese children examined was consistent with recommendations. In this group, the ferroportin/hepcidin ratio positively correlated with energy intake (p = 0.012), dietary iron (p = 0.003) and vitamin B12 (p = 0.024). In the multivariate regression model an association between the ferroportin/hepcidin ratio and the sTfR/ferritin index in obese children (beta = 0.399, p = 0.017) was found. These associations did not exist in the controls. The results obtained suggest that in obese children with sufficient iron intake, the altered ferroportin-hepcidin axis may occur without signs of iron deficiency or iron deficiency anemia. The role of other micronutrients, besides dietary iron, may also be considered in the iron status of these children.

AB - Chemical examination of the EtOAc extract of the deep sea-derived fungus Penicillium sp. YPGA11 resulted in the isolation of four new farnesylcyclohexenones, peniginsengins B-E (1-4), and a known analog peniginsengin A (5). The structures of compounds 1-4 were determined on the basis of comprehensive analyses of the nuclear magnetic resonance (NMR) and mass spectroscopy (MS) data, and the absolute configurations of 1, 2, and 4 were determined by comparisons of experimental electronic circular dichroism (ECD) with calculated ECD spectra. Compounds 1-5, characterized by a highly oxygenated 1-methylcyclohexene unit and a (4E,8E)-4,8-dimethyldeca-4,8-dienoic acid side chain, are rarely found in nature. Compounds 2-4 exhibited antibacterial activity against Staphylococcus aureus. PMID- 30275365 TI - Safety Lapses Prior to Initiation of Hemodialysis for Acute Kidney Injury in Hospitalized Patients: A Patient Safety Initiative. AB - Background: Safety lapses in hospitalized patients with acute kidney injury (AKI) may lead to hemodialysis (HD) being required before renal recovery might have otherwise occurred. We sought to identify safety lapses that, if prevented, could reduce the need for unnecessary HD after AKI; Methods: We conducted a retrospective observational study that included consecutive patients treated with HD for AKI at a large, tertiary academic center between 1 September 2015 and 31 August 2016. Exposures of interest were pre-specified iatrogenic processes that could contribute to the need for HD after AKI, such as nephrotoxic medication or potassium supplement administration. Other outcomes included time from AKI diagnosis to initial management steps, including Nephrology referral; Results: After screening 344 charts, 80 patients were included for full chart review, and 264 were excluded because they required HD within 72 h of admission, were deemed to have progression to end-stage kidney disease (ESKD), or required other renal replacement therapy (RRT) modalities in critical care settings such as continuous renal replacement therapy (CRRT) or sustained low efficiency dialysis (SLED). Multiple safety lapses were identified. Sixteen patients (20%) received an angiotensin converting enzyme inhibitor or angiotensin receptor blocker after AKI onset. Of 35 patients with an eventual diagnosis of pre-renal AKI due to hypovolemia, only 29 (83%) received a fluid bolus within 24 h. For 28 patients with hyperkalemia as an indication for starting HD, six (21%) had received a medication associated with hyperkalemia and 13 (46%) did not have a low potassium diet ordered. Nephrology consultation occurred after a median (IQR) time after AKI onset of 3.0 (1.0-5.7) days; Conclusions: Although the majority of patients had multiple indications for the initiation of HD for AKI, we identified many safety lapses related to the diagnosis and management of patients with AKI. We cannot conclude that HD initiation was avoidable, but, improving safety lapses may delay the need for HD initiation, thereby allowing more time for renal recovery. Thus, development of automated processes not only to identify AKI at an early stage but also to guide appropriate AKI management may improve renal recovery rates. PMID- 30275366 TI - Accurate Weed Mapping and Prescription Map Generation Based on Fully Convolutional Networks Using UAV Imagery. AB - Chemical control is necessary in order to control weed infestation and to ensure a rice yield. However, excessive use of herbicides has caused serious agronomic and environmental problems. Site specific weed management (SSWM) recommends an appropriate dose of herbicides according to the weed coverage, which may reduce the use of herbicides while enhancing their chemical effects. In the context of SSWM, the weed cover map and prescription map must be generated in order to carry out the accurate spraying. In this paper, high resolution unmanned aerial vehicle (UAV) imagery were captured over a rice field. Different workflows were evaluated to generate the weed cover map for the whole field. Fully convolutional networks (FCN) was applied for a pixel-level classification. Theoretical analysis and practical evaluation were carried out to seek for an architecture improvement and performance boost. A chessboard segmentation process was used to build the grid framework of the prescription map. The experimental results showed that the overall accuracy and mean intersection over union (mean IU) for weed mapping using FCN-4s were 0.9196 and 0.8473, and the total time (including the data collection and data processing) required to generate the weed cover map for the entire field (50 * 60 m) was less than half an hour. Different weed thresholds (0.00-0.25, with an interval of 0.05) were used for the prescription map generation. High accuracies (above 0.94) were observed for all of the threshold values, and the relevant herbicide saving ranged from 58.3% to 70.8%. All of the experimental results demonstrated that the method used in this work has the potential to produce an accurate weed cover map and prescription map in SSWM applications. PMID- 30275367 TI - Highly Integrated All-Fiber FP/FBG Sensor for Accurate Measurement of Strain under High Temperature. AB - Accurate measurement of strain is one of the most important issues for high temperature environments. We present a highly integrated all-fiber sensor to achieve precise measurements of strain/high-pressure, which consists of a fiber Bragg grating (FBG) inscribed by an 800 nm femtosecond laser cascaded with a micro extrinsic Fabry-Perot (FP) cavity fabricated by the 157 nm laser micromachining technique. FBG is sensitive to temperature, but insensitive to strain/pressure, whereas the FP is sensitive to strain/pressure, but has a small dependence on temperature. Therefore, such a cascaded sensor could be used for dual-parameter measurement and can work well at high temperatures. Experimental results indicate that this device exhibits a good strain characteristic at high temperatures and excellent high-pressure performance at room temperature. Due to its highly sensitive wavelength response, the proposed sensor will have remarkable potential applications in dual parameter sensing in harsh environments. PMID- 30275369 TI - Low-Cost Graphite on Paper Pressure Sensor for a Robot Gripper with a Trivial Fabrication Process. AB - A flexible pressure sensor with a rudimentary, ultra-low cost, and solvent-free fabrication process is presented in this paper. The sensor has a graphite-on paper stacked paper structure, which deforms and restores its shape when pressure is applied and released, showing an exceptionally fast response and relaxation time of ~0.4 ms with a sensitivity of -5%/Pa. Repeatability of the sensor over 1000 cycles indicates an excellent long-term stability. The sensor demonstrated fast and reliable human touch interface, and successfully integrated into a robot gripper to detect grasping forces, showing high promise for use in robotics, human interface, and touch devices. PMID- 30275368 TI - Reduced Carotenoid and Retinoid Concentrations and Altered Lycopene Isomer Ratio in Plasma of Atopic Dermatitis Patients. AB - Carotenoids and retinoids are known to alter the allergic response with important physiological roles in the skin and the immune system. In the human organism various carotenoids are present, some of which are retinoid precursors. The bioactive derivatives of these retinoids are the retinoic acids, which can potently activate nuclear hormone receptors such as the retinoic acid receptor and the retinoid X receptor. In this study, we aimed to assess how plasma carotenoid and retinoid concentrations along with the ratio of their isomers are altered in atopic dermatitis (AD) patients (n = 20) compared to healthy volunteers (HV, n = 20). The study indicated that plasma levels of the carotenoids lutein (HV 198 +/- 14 ng/mL, AD 158 +/- 12 ng/mL, p = 0.02; all values in mean +/- SEM), zeaxanthin (HV 349 +/- 30 ng/mL, AD 236 +/- 18 ng/mL, p <= 0.01), as well as the retinoids retinol (HV 216 +/- 20 ng/mL, AD 167 +/- 17 ng/mL, p = 0.04) and all-trans-retinoic acid (HV 1.1 +/- 0.1 ng/mL, AD 0.7 +/- 0.1 ng/mL, p = 0.04) were significantly lower in the AD-patients, while lycopene isomers, alpha-carotene, and beta-carotene levels were comparable to that determined in the healthy volunteers. In addition, the ratios of 13-cis- vs. all trans-lycopene (HV 0.31 +/- 0.01, AD 0.45 +/- 0.07, p = 0.03) as well as 13-cis- vs. all-trans-retinoic acid (HV 1.4 +/- 0.2, AD 2.6 +/- 0.6, p = 0.03) were increased in the plasma of AD-patients indicating an AD-specific 13-cis isomerisation. A positive correlation with SCORAD was calculated with 13-cis- vs. all-trans-lycopene ratio (r = 0.40, p = 0.01), while a negative correlation was observed with zeaxanthin plasma levels (r = -0.42, p = 0.01). Based on our results, we conclude that in the plasma of AD-patients various carotenoids and retinoids are present at lower concentrations, while the ratio of selected lycopene isomers also differed in the AD-patient group. An increase in plasma isomers of both lycopene and retinoic acid may cause an altered activation of nuclear hormone receptor signaling pathways and thus may be partly responsible for the AD-phenotype. PMID- 30275371 TI - Correlations of Self-Reported Androgen Deficiency in Ageing Males (ADAM) with Stress and Sleep among Young Adult Males. AB - Androgen deficiency in males has traditionally been predominantly limited to older men aged 50+ years. However, little is known of the correlation between hormonal disruption, stress, and sleep in college-aged males. This cross sectional study investigates lifestyle behavior patterns in young men and a screening for potential androgen deficiency. A survey of 409 male students, as part of a larger USDA-funded GetFruved study, was analyzed for this subproject. Survey instruments used include the Androgen Deficiency in the Aging Male Questionnaire (ADAM) to assess for inadequate ADAM scores, the Perceived Stress Scale to measure stress levels and the Pittsburgh Sleep Quality Index to evaluate sleep quality. In total, 144 male participants (35%) met criteria for potential androgen deficiency defined by the ADAM questionnaire. Correlation was found between having a positive ADAM score and both increased stress levels (p < 0.001) and poor sleep quality (p < 0.001), with stress displaying the strongest effect (p < 0.001 vs p = 0.124). An increased prevalence of having a positive ADAM score versus established norms for this age group was also noted. These findings highlight the need for investigation of endocrine disruptions in young men. PMID- 30275370 TI - Impact of Sarcopenia as a Prognostic Biomarker of Bladder Cancer. AB - Sarcopenia, the degenerative and systemic loss of skeletal muscle mass, indicates patient frailty and impaired physical function. Sarcopenia can be caused by multiple factors, including advanced age, lack of exercise, poor nutritional status, inflammatory diseases, endocrine diseases, and malignancies. In patients with cancer cachexia, anorexia, poor nutrition and systemic inflammation make the metabolic state more catabolic, resulting in sarcopenia. Thus, sarcopenia is considered as one of manifestations of cancer cachexia. Recently, growing evidence has indicated the importance of sarcopenia in the management of patients with various cancers. Sarcopenia is associated with not only higher rates of treatment-related complications but also worse prognosis in cancer-bearing patients. In this article, we summarized metabolic backgrounds of cancer cachexia and sarcopenia and definitions of sarcopenia based on computed tomography (CT) images. We conducted a systematic literature review regarding the significance of sarcopenia as a prognostic biomarker of bladder cancer. We also reviewed recent studies focusing on the prognostic role of changes in skeletal muscle mass during the course of treatment in bladder cancer patients. Lastly, we discussed the impact of nutritional support, medication, and exercise on sarcopenia in cancer bearing patients.

It has been demonstrated that the photocurrent can be enhanced by a factor of 5 relative to Zn-perylene MOF thin film due to triplet-triplet annihilation up-conversion between the Bodipy/PMMA sensitizer and the Zn-perylene MOF thin film acceptor using Co(bpy)32+/3+ as redox mediator. PMID- 30275373 TI - Enhancing the Number of Modes in Metasurfaced Reverberation Chambers for Field Uniformity Improvement. AB - The use of metasurfaces to increase the number of modes, lower the operating frequency, and improve the field uniformity in reverberation chambers (RCs) is investigated in this paper. The method used to improve the field uniformity and decrease the resonance frequencies is based on increasing the number of modes by using the concept of subwavelength cavities. The resonance frequencies of a RC with metasurface wall are derived and expressed analytically in terms of macroscopic characteristics. Simulation of the reflection phase of the unit cell is then given as a guideline to choose the required microscopic parameters of the designed metasurface. The mode density in such subwavelength RCs is then obtained using a numerical eigenmode solver. Compared to traditional RCs, a much higher modal density is obtained at low frequencies. The standard deviation of the field uniformity in the test volume of the RC corresponding to different types of metasurface walls is finally compared. It is shown that by increasing the number of modes in the RC at the lower band, the operating frequency decreases and the field uniformity of the RC is improved.

AB - This study aims to understand the relationship between bedroom privacy and well being of the elderly in aged care facilities with a compact living situation. A majority of studies on this topic were carried out in a low-density population context. The crowded living situation might compromise the well-being of residents. This study proposed five architectural parameters to measure bedroom privacy in aged care facilities: total open surface per unit, openness/solid ratio per bed, height of partition wall, number of people per unit, and personal control over bedroom privacy. SF-12 v.2 Health Survey was used to collect information on physical and mental health status. The study surveyed nine Care & Attention homes and their 213 residents in Hong Kong. The total open surface per unit and the openness/solid ratio per bed were positively associated with the physical health of residents. The height of partition walls was associated negatively with their physical and mental health conditions, and the number of people per unit was negatively associated with their physical health. More than half of respondents preferred a single unit with high partition walls; however, 40% of respondents preferred low partition walls. The provision of privacy for the elderly should be balanced with their needs for social interactions; total open surface per unit, openness/solid ratio per bed and height of partition wall should be taken into consideration. The study provides evidence and design guidelines for improving privacy in aged care facilities with a compact living environment.

AB - Systematic and deep understanding of mechanical properties of the negative Poisson's ratio convex-concave foams plays a very important role for their practical engineering applications. However, in the open literature, only a negative Poisson's ratio effect of the metamaterials convex-concave foams is simply mentioned. In this paper, through the experimental and finite element methods, effects of geometrical morphology on elastic moduli, energy absorption, and damage properties of the convex-concave foams are systematically studied. Results show that negative Poisson's ratio, energy absorption, and damage properties of the convex-concave foams could be tuned simultaneously through adjusting the chord height to span ratio of the sine-shaped cell edges. By the rational design of the negative Poisson's ratio, when compared to the conventional open-cell foams of equal mass, convex-concave foams could have the combined advantages of relative high stiffness and strength, enhanced energy absorption and damage resistance. The research of this paper provides theoretical foundations for optimization design of the mechanical properties of the convex concave foams and thus could facilitate their practical applications in the engineering fields.

AB - The clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9 (CRISPR/Cas9) gene editing system has been shown to be able to induce highly efficient mutagenesis in the targeted DNA of many plants, including cotton, and has become an important tool for investigation of gene function and crop improvement. Here, we developed a simple and easy to operate CRISPR/Cas9 system and demonstrated its high editing efficiency in cotton by targeting-ALARP, a gene encoding alanine-rich protein that is preferentially expressed in cotton fibers. Based on sequence analysis of the target site in the 10 transgenic cottons containing CRISPR/Cas9, we found that the mutation frequencies of GhALARP A and GhALARP-D target sites were 71.4-100% and 92.9-100%, respectively. The most common editing event was deletion, but deletion together with large insertion was also observed. Mosaic mutation editing events were detected in most transgenic plants. No off-target mutation event was detected in any the 15 predicted sites analyzed. This study provided mutants for further study of the function of GhALARP in cotton fiber development. Our results further demonstrated the feasibility of use of CRISPR/Cas9 as a targeted mutagenesis tool in cotton, and provided an efficient tool for targeted mutagenesis and functional genomics in cotton. PMID- 30275377 TI - Decreased Capacity for Sperm Production Induced by Perinatal Bisphenol A Exposure Is Associated with an Increased Inflammatory Response in the Offspring of C57BL/6 Male Mice. AB - Many previous studies have indicated the adverse effects of bisphenol A (BPA) on sperm production and quality; however, the mechanisms underlying BPA male reproductive toxicity have yet to be elucidated. The main purpose of this study was to investigate the effect of perinatal exposure to BPA on the spermatogenic capacity of male offspring, and to explore the possible influence of inflammatory responses in BPA reproductive toxicity. Twenty-one pregnant C57BL/6mice were randomly divided into three groups: a control group, a group receiving 0.2 MUg/mL (LBPA), and a group receiving 2 MUg/mL of BPA (HBPA), all via drinking water from gestational day 6 to the end of lactation. After weaning, one male mouse was randomly selected from each group (n = 7/group); these three mice were fed a normal diet and drinking water for 1 month. Levels of serum testosterone (T) and tumor necrosis factor (TNF)-alpha were then measured in all mice. Sperm count and the proportion of sperm malformation were also determined. The levels of Toll like receptor 4 (TLR4), nuclear factor (NF)-kappaB, and aryl hydrocarbon receptor (AhR) protein expression in the testis tissue were determined. Analysis showed that the proportion of sperm malformation increased in the LBPA and HBPA groups (p < 0.05). Sperm count significantly decreased only in the HBPA group (p < 0.05), while the levels of serum TNF-alpha increased in the LBPA and HBPA groups (p < 0.05). Levels of serum T decreased significantly in the HBPA group, compared with controls (p < 0.05). Levels of TLR4 and NF-kappaB protein expression in the testis were significantly higher in the LBPA and HBPA groups (p < 0.05 or p < 0.01), while AhR protein expression was higher and seminiferous tubules in the testis showed more damage in the HBPA group compared to controls (p < 0.05 and p < 0.01, respectively). Our results showed that perinatal exposure to low or high doses of BPA decreased the capacity for spermatogenesis in male offspring, which may be associated with an inflammatory response activated by the TLR4/ NF-kappaB and AhR signaling pathways in the testis. PMID- 30275378 TI - Extensive Contamination of Water with Saxitoxin Near the Dam of the Irkutsk Hydropower Station Reservoir (East Siberia, Russia). AB - An area of discolored water 50 m wide and 30 m long was found in September 2017 close to the dam of the Irkutsk hydroelectric power station. Water from this spot was sampled for investigation in the present study. Microscopic analysis revealed that the suspended matter in the sample was composed of clumps of filaments, vegetative cells, akinetes and heterocysts that formed short filaments and solitary cells. This matter was found to consist of partially degraded cells of the cyanobacterium Dolichospermum lemmermannii. Nucleotide sequencing of DNA isolated from the biomass revealed the presence of the sxtA gene which is involved in the synthesis of saxitoxin. Water from the polluted area contained 600 +/- 100 MUg L-1 saxitoxin as measured by HPLC-MS with pre-column modification of the toxin with 2,4-dinitrophenylhydrazine. Immunoassay analysis (ELISA) showed a concentration of saxitoxins in the water of 2900 +/- 900 MUg L-1. Hydrochemical and microbiological analyses suggested the contaminated area appeared as a result of a D. lemmermannii bloom, followed by its decay and release of saxitoxin and nutrients. The present paper describes the results of a case study. Better understanding of the phenomenon will depend on the possibility to perform implementation of a large-scale monitoring program. PMID- 30275379 TI - The Impact of Health Insurance Policy on the Health of the Senior Floating Population-Evidence from China. AB - The impact of health insurance on residents' health is one of the focal points of academic research. Due to the fact that China's medical insurance system is composed of a variety of programs and that the pooling districts are at the lower administrative level, enrollment in different medical insurance programs or at different places may have certain influences on the health of residents. This has mostly been neglected by previous studies. This paper uses data from the 2015 China Migrants Dynamic Survey (CMDS), focusing on the senior floating population and taking the difference in government subsidy proportions as an instrumental variable in order to identify the effects of health insurance programs and regional differences on the health of the senior floating population. Three effects were observed: First, participation in the health insurance system significantly improves floating seniors' self-rated health. Second, the health status of floating seniors affects their choice of health insurance program: Less healthy persons tend to choose high-paying, wide-coverage basic medical insurance available for urban employees. Using an instrumental variable to control for the problem of endogeneity, it is discovered that compared with the basic medical insurance system for urban residents, the system for urban employees significantly enhances the health of the senior floating population. Third, "adverse selection" could be observed in the choice between enrolling in health insurance at the place of settlement or another place. Senior migrants with worse self-rated health tend to choose place of settlement in order to enjoy higher compensation and less complex reimbursement procedures. With an instrumental variable to control for the problem of endogeneity, it was found that compared with joining the medical insurance system at other places, joining at a place of settlement could improve the health of the floating senior population. PMID- 30275381 TI - A Study on the Effect of Ultrasonic Treatment on the Microstructure of Sn-30 wt.% Bi Alloy. AB - The effect of ultrasonic treatment on the microstructure of Sn-30 wt.% Bi alloy was studied at different temperatures. Results showed that the ultrasonic treatment could effectively refine the microstructure of Sn-30 wt.% Bi alloy at a temperature range between the liquidus and solidus. Application of the ultrasound could fragment the primary Sn dendrites during solidification due to a mixed effect of ultrasonic cavitation and acoustic streaming. The divorced eutectic formed when the ultrasonic treatment was applied for the whole duration of the solidification. The eutectic phase grew and surrounded the primary Sn dendrite, and pure Bi phase grew in between the Sn dendritic fragments. The mechanism of the fragmentation of dendrites and the divorced eutectic structure by ultrasonic treatment was discussed. PMID- 30275380 TI - Impact of Coffee, Wine, and Chocolate Consumption on Cognitive Outcome and MRI Parameters in Old Age. AB - Coffee, wine and chocolate are three frequently consumed substances with a significant impact on cognition. In order to define the structural and cerebral blood flow correlates of self-reported consumption of coffee, wine and chocolate in old age, we assessed cognition and brain MRI measures in 145 community-based elderly individuals with preserved cognition (69 to 86 years). Based on two neuropsychological assessments during a 3-year follow-up, individuals were classified into stable-stable (52 sCON), intermediate (61 iCON) and deteriorating deteriorating (32 dCON). MR imaging included voxel-based morphometry (VBM), tract based spatial statistics (TBSS) and arterial spin labelling (ASL). Concerning behavior, moderate consumption of caffeine was related to better cognitive outcome. In contrast, increased consumption of wine was related to an unfavorable cognitive evolution. Concerning MRI, we observed a negative correlation of wine and VBM in bilateral deep white matter (WM) regions across all individuals, indicating less WM lesions. Only in sCON individuals, we observed a similar yet weaker association with caffeine. Moreover, again only in sCON individuals, we observed a significant positive correlation between ASL and wine in overlapping left parietal WM indicating better baseline brain perfusion. In conclusion, the present observations demonstrate an inverse association of wine and coffee consumption with cognitive performances. Moreover, low consumption of wine but also moderate to heavy coffee drinking was associated with better WM preservation and cerebral blood-flow notably in cognitively stable elders. PMID- 30275382 TI - High-Performance Thin Film Transistor with an Neodymium-Doped Indium Zinc Oxide/Al2O3 Nanolaminate Structure Processed at Room Temperature. AB - In this work, a high-performance thin film transistor with an neodymium-doped indium zinc oxide (Nd:IZO) semiconductor via a room temperature approach and adopting the Nd:IZO/Al2O3 nanolaminate structure was investigated. The effects of the ultrathin Al2O3 layer and the thickness of Nd:IZO layer in the nanolaminate structure on the improvement of electrical performance and stability of thin film transistors (TFTs) were systematically studied. Besides the carrier movement confined along the near-channel region, driven by the Al2O3 layer under an electrical field, the high performance of the TFT is also attributed to the high quality of the 8-nm-thick Nd:IZO layer and the corresponding optimal Nd:IZO/Al2O3 interface, which reduce the scattering effect and charge trapping with strong M-O bonds in bulk and the back-channel surface of Nd:IZO, according to the X-ray reflectivity (XRR), X-ray photoelectron spectroscopy (XPS), and micro-wave photo conductivity decay (MU-PCD) results. As a result, the Nd:IZO/Al2O3 TFT exhibits an outstanding performance, with a high MUsat of 32.7 cm2.V-1.s-1, an Ion/Ioff of 1.9 * 108, and a low subthreshold swing (SS) value of 0.33 V.dec-1, which shows great potential for the room temperature fabrication of TFTs in high-resolution or high-frame-rate displays by a scalable, simple, and feasible approach. PMID- 30275384 TI - Short-Term Effects of Ambient Air Pollution on Hospitalization for Respiratory Disease in Taiyuan, China: A Time-Series Analysis. AB - In this study, we estimated the short-term effects of ambient air pollution on respiratory disease hospitalization in Taiyuan, China. Daily data of respiratory disease hospitalization, daily concentration of ambient air pollutants and meteorological factors from 1 October 2014 to 30 September 2017 in Taiyuan were included in our study. We conducted a time-series study design and applied a generalized additive model to evaluate the association between every 10-MUg/m3 increment of air pollutants and percent increase of respiratory disease hospitalization. A total of 127,565 respiratory disease hospitalization cases were included in this study during the present period. In single-pollutant models, the effect values in multi-day lags were greater than those in single-day lags. PM2.5 at lag02 days, SO2 at lag03 days, PM10 and NO2 at lag05 days were observed to be strongly and significantly associated with respiratory disease hospitalization. No significant association was found between O3 and respiratory disease hospitalization. SO2 and NO2 were still significantly associated with hospitalization after adjusting for PM2.5 or PM10 into two-pollutant models. Females and younger population for respiratory disease were more vulnerable to air pollution than males and older groups. Therefore, some effective measures should be taken to strengthen the management of the ambient air pollutants, especially SO2 and NO2, and to enhance the protection of the high-risk population from air pollutants, thereby reducing the burden of respiratory disease caused by ambient air pollution. PMID- 30275385 TI - Ghrelin in Serum and Urine of Post-Partum Women with Gestational Diabetes Mellitus. AB - Women with a previous history of gestational diabetes mellitus (GDM) have a significantly increased risk of developing type 2 diabetes, obesity, and cardiovascular diseases in the future. The aim of the study was to evaluate ghrelin concentrations in serum and urine in the GDM group in the early post partum period, with reference to laboratory results, body composition, and hydration status. The study subjects were divided into two groups, that is, 28 healthy controls and 26 patients with diagnosed GDM. The maternal body composition and hydration status were evaluated by the bioelectrical impedance analysis (BIA) method. The concentrations of ghrelin in the maternal serum and urine were determined via enzyme-linked immunosorbent assay (ELISA). The laboratory and BIA results of the mothers with GDM were different from those without GDM. Urine ghrelin positively correlated with serum ghrelin and high density lipoprotein cholesterol (HDL) levels in healthy mothers. There were direct correlations between urine ghrelin and HDL as well as triglycerides levels in the GDM group. Neither the lean tissue index nor body cell mass index were related to the serum ghrelin concentrations in this group. Only the urine ghrelin of healthy mothers correlated with the fat tissue index. Our results draw attention to urine as an easily available and appropriable biological material for further studies. PMID- 30275383 TI - Branched-Chain Amino Acid Database Integrated in MEDIPAD Software as a Tool for Nutritional Investigation of Mediterranean Populations. AB - Branched-chained amino acids (BCAA) are essential dietary components for humans and can act as potential biomarkers for diabetes development. To efficiently estimate dietary intake, we developed a BCAA database for 1331 food items found in the French Centre d'Information sur la Qualite des Aliments (CIQUAL) food table by compiling BCAA content from international tables, published measurements, or by food similarity as well as by calculating 267 items from Greek, Turkish, Romanian, and Moroccan mixed dishes. The database embedded in MEDIPAD software capable of registering 24 h of dietary recalls (24HDR) with clinical and genetic data was evaluated based on archived 24HDR of the Saint Pierre Institute (France) from 2957 subjects, which indicated a BCAA content up to 4.2 g/100 g of food and differences among normal weight and obese subjects across BCAA quartiles. We also evaluated the database of 119 interviews of Romanians, Turkish and Albanians in Greece (27-65 years) during the MEDIGENE program, which indicated mean BCAA intake of 13.84 and 12.91 g/day in males and females, respectively, comparable to other studies. The MEDIPAD is user-friendly, multilingual, and secure software and with the BCAA database is suitable for conducting nutritional assessment in the Mediterranean area with particular facilities for food administration. PMID- 30275386 TI - Erythrocyte Saturated Fatty Acids and Incident Type 2 Diabetes in Chinese Men and Women: A Prospective Cohort Study. AB - The association between circulating saturated fatty acids (SFAs) and incident type 2 diabetes (T2D) is reported in Western populations with inconsistent results, while evidence from Asian populations is scarce. We aimed to examine the associations between erythrocyte SFAs and incident T2D in a Chinese population. Between 2008 and 2013, a total of 2683 participants, aged 40-75 years, free of diabetes were included in the present analyses. Incident T2D cases were ascertained during follow-up visits. Gas chromatography was used to measure erythrocyte fatty acids at baseline. The Cox proportional hazards model was used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs). During 13,508 person years of follow-up, 216 T2D cases were identified. Compared with the first quartile, multivariable-adjusted HRs (95% CIs) of the fourth quartile were 1.20 (0.82-1.76; p = 0.242) for myristic acid (14-carbon tail, zero double bonds; 14:0), 0.69 (0.48-0.99; p = 0.080) for palmitic acid (16:0), 1.49 (1.02 2.19; p = 0.047) for stearic acid (18:0), 1.46 (1.00-2.12; p = 0.035) for arachidic acid (20:0), 1.48 (0.99-2.22; p = 0.061) for behenic acid (22:0), and 1.08 (0.74-1.56; p = 0.913) for lignoceric acid (24:0). Our findings indicate that individual erythrocyte SFAs are associated with T2D in different directions, with 18:0 and 20:0 SFAs positively associated with the risk, whereas no convincing inverse association for 16:0 SFAs. PMID- 30275387 TI - The Dislike of Hot Thermal Conditions and Its Relationship with Sun (Ultraviolet Radiation) Exposure in the Southeastern United States. AB - We investigated the relationship between peoples' preferences for being outside during certain months of the year, based upon their dislike of hot or warm temperatures, and of taking precautions against ultraviolet radiation (UVR) exposure. A sample of university undergraduates (N = 1400) living in the Northern Hemisphere completed an online survey in the late summer of 2017 that inventoried their dislike of heat and hot conditions, their sun tanning preferences and habits, and their preferences for being outside during different months of the year, along with whether they would protect themselves from the UVR exposure during those months. Dislike of hot conditions was negatively correlated with respondent preferences for sun tanning and with the number of months during the year that people enjoyed being active outside. A greater proportion of people who disliked hot conditions experienced risks of UVR overexposure during the spring and fall. In contrast, people who expressed more liking of heat frequently enjoyed being outside during the warmer months (April to October), and a significantly greater proportion of them experienced risks for sun overexposure in these months. Such individual differences in heat-related attitudes may explain a proportion the variability in individual risk behaviors for skin cancer that is not currently accounted for by approaches using objective variables such as temperature, thermal comfort indices, or the UV index. PMID- 30275388 TI - AbeTx1 Is a Novel Sea Anemone Toxin with a Dual Mechanism of Action on Shaker Type K+ Channels Activation. AB - Voltage-gated potassium (KV) channels regulate diverse physiological processes and are an important target for developing novel therapeutic approaches. Sea anemone (Cnidaria, Anthozoa) venoms comprise a highly complex mixture of peptide toxins with diverse and selective pharmacology on KV channels. From the nematocysts of the sea anemone Actinia bermudensis, a peptide that we named AbeTx1 was purified and functionally characterized on 12 different subtypes of KV channels (KV1.1-KV1.6; KV2.1; KV3.1; KV4.2; KV4.3; KV11.1; and, Shaker IR), and three voltage-gated sodium channel isoforms (NaV1.2, NaV1.4, and BgNaV). AbeTx1 was selective for Shaker-related K+ channels and is capable of inhibiting K+ currents, not only by blocking the K+ current of KV1.2 subtype, but by altering the energetics of activation of KV1.1 and KV1.6. Moreover, experiments using six synthetic alanine point-mutated analogs further showed that a ring of basic amino acids acts as a multipoint interaction for the binding of the toxin to the channel. The AbeTx1 primary sequence is composed of 17 amino acids with a high proportion of lysines and arginines, including two disulfide bridges (Cys1-Cys4 and Cys2-Cys3), and it is devoid of aromatic or aliphatic amino acids. Secondary structure analysis reveals that AbeTx1 has a highly flexible, random-coil-like conformation, but with a tendency of structuring in the beta sheet. Its overall structure is similar to open-ended cyclic peptides found on the scorpion kappa KTx toxins family, cone snail venoms, and antimicrobial peptides. PMID- 30275389 TI - Removal of Cr (VI) from Simulated and Leachate Wastewaters by Bentonite-Supported Zero-Valent Iron Nanoparticles. AB - Zero-valent iron (Fe0) nanoparticles (NPs) have shown excellent ability to remove contaminants hexavalent chromium (Cr(VI)) from aquatic systems. Use of support materials can help to prevent oxidation and aggregation of Fe0NPs, and thus enhance their remediation efficiency. However, most previous studies were conducted using artificially synthetic wastewater, and little is known on the remediation effects of supported Fe0NPs on actual wastewaters containing Cr(VI). Here, bentonite-supported Fe0NPs (BFe0NPs) with 1-5% of bentonite were prepared and characterized using scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. Batch experiments were performed to study Cr(VI) removal by the selected BFe0NPs from a simulated wastewater and a leachate wastewater originating from a Cr slag heap-polluted soil. The results show that Fe0NPs were uniformly dispersed on the bentonite, leading to a decreased aggregation of NPs, and the optimal mass ratio of bentonite was 4%. Batch experiment results show that lower pH values favored Cr(VI) removal by BFe0NPs. The removal percentage of Cr(VI) was higher than 90% for both wastewaters when the pH value was 2.0, but decreased significantly as pH value increased. Cr(VI) removal reaction was quite fast within the initial 10 min, and at least 85% of Cr(VI) was removed for both wastewaters. Cr(VI) removal percentage increased with increasing BFe0NPs dosages ranging from 30 to 60, but remained almost unchanged when the Fe/Cr mass ratio increased to above 60. The reaction of BFe0NPs to remove Cr(VI) followed the pseudo second-order reaction model. In most cases, the removal rates of Cr(VI) were higher in simulated wastewater than in leachate wastewater, but all approached 100% at the optimal conditions. Our present results show that BFe0NPs with 4% bentonite are efficient for treatment of Cr(VI)-containing wastewaters. PMID- 30275390 TI - Development of an Oral Compound Pickering Emulsion Composed of Nanocrystals of Poorly Soluble Ingredient and Volatile Oils from Traditional Chinese Medicine. AB - In this study, an oral drug nanocrystals self-stabilized Pickering emulsion (NSSPE), which used nanocrystals of a poorly soluble ingredient from Puerariae Radix called puerarin as solid particle stabilizers and Ligusticum chuanxiong essential oil since the main oil phase had been developed to improve the oral bioavailability of puerarin. The appearance of emulsions, size and zeta potential of droplets, and content of puerarin in emulsified layer during a storage of six months at 4, 25, and 40 degrees C were investigated. The centrifugation stability at 4000* g was also studied. The micro-structure of emulsion droplets was characterized by a scanning electron micrograph (SEM), confocal laser scanning microscopy (CLSM), a fluorescence microscope (FM), and differential scanning calorimetry (DSC). The in vivo oral bioavailability of puerarin NSSPE was investigated in rats. Results showed that appearances of puerarin NSSPE kept stable after centrifugation at 4000* g for 15 min or storage for six months at 4, 25, and 40 degrees C. SEM, CLSM, FM, and DSC showed that the puerarin NSSPE had a stable core-shell structure of emulsion droplets formed by the adsorption of puerarin nanocrystals on the surface of oil droplets of mixed oil of Ligusticum chuanxiong essential oil and Labrafil M 1944 CS (9:1, v/v). The relative bioavailability of puerarin NSSPE to puerarin coarse powder suspension, nanocrystal suspension, and surfactant emulsion were 262.43%, 155.92%, and 223.65%, respectively. All these results indicated that puerarin nanocrystals could stabilize Pickering emulsion of Ligusticum chuanxiong essential oil without any other stabilizers and Pickering emulsion could improve the oral bioavailability of puerarin, which suggests that the drug nanocrystal self stabilized Pickering emulsion as a promising oral drug delivery system for Traditional Chinese Medicine containing poorly soluble ingredients and volatile oils. PMID- 30275391 TI - Aurantoside C Targets and Induces Apoptosis in Triple Negative Breast Cancer Cells. AB - Triple negative breast cancer (TNBC) is a subtype of breast cancers that currently lacks effective targeted therapy. In this study, we found that aurantoside C (C828), isolated from the marine sponge Manihinea lynbeazleyae collected from Western Australia, exhibited higher cytotoxic activities in TNBC cells compared with non-TNBC (luminal and normal-like) cells. The cytotoxic effect of C828 was associated to the accumulation of cell at S-phase, resulting in the decline of cyclin D1, cyclin E1, CDK4, and CDK6, and an increase in p21. We also found that C828 inhibited the phosphorylation of Akt/mTOR and NF-kB pathways and increased the phosphorylation of p38 MAPK and SAPK/JNK pathways, leading to apoptosis in TNBC cells. These effects of C828 were not observed in non-TNBC cells at the concentrations that were cytotoxic to TNBC cells. When compared to the cytotoxic effect with the chemotherapeutic drugs doxorubicin and cisplatin, C828 was found to be 20 times and 35 times more potent than doxorubicin and cisplatin, respectively. These results indicate that C828 could be a promising lead for developing new anticancer agents that target TNBC cells. PMID- 30275393 TI - Reinforcement of Stearic Acid Treated Egg Shell Particles in Epoxy Thermosets: Structural, Thermal, and Mechanical Characterization. AB - This work reports the modification of egg shell (ES) particles by using stearic acid (SA) and their reinforcement in the epoxy matrix. The ES treatment via SA was optimized, the optimum conditions for concentration, temperature, and time were found to be 2.5%, 85 degrees C, and 50 min, respectively. The untreated ES (UES) and treated ES (TES) particles were characterized by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), X-ray diffraction (XRD), scanning electron microscope (SEM), particle size distribution, and contact angle. FTIR confirmed the chemical modification of SA on ES surface and DSC reflects an endothermic peak at 240 degrees C. XRD reveal a decrease in crystal size and crystallinity, while contact angle increases to 169 degrees from 42 degrees . The SEM observations clearly reflect a distinct decrease and separation of small domains of ES particles thus improving an increased surface area. Afterwards, the UES and TES particles were reinforced in epoxy at 15 and 20 weight (wt.) % loading. The tensile tests confirmed a 22% increase in elongation as compared to pure epoxy due to the hydrogen bonding between TES particles and matrix. The lowest brittleness was recorded for TES/epoxy composites on 20 wt % loading. The TGA confirmed the improved thermal stabilities at 20 wt % loading of TES particles in matrix, the improvements in T5%, T10%, and T20% values were recorded as 33, 26, and 21 degrees C higher than the corresponding values for neat matrix. The TES/epoxy composites on 20 wt % showed 41% increase in storage modulus as compared to the pristine epoxy, and cross-link density reaches to 2.71 * 10-3 from 1.29 * 10-3 mol/cm3 for neat matrix. The decline in tan delta height and improvement in Tg were also observed. The best adhesion effectiveness was recorded for TES/epoxy composites. This simple and economical modification technique can enhance the application of ES particles in various polymeric coating and composites applications. PMID- 30275394 TI - Interlaminar Shear Properties of Z-Pinned Carbon Fiber Reinforced Aluminum Matrix Composites by Short-Beam Shear Test. AB - This paper presents the effect of through-thickness reinforcement by steel z-pins on the interlaminar shear properties and strengthening mechanisms of carbon fiber reinforced aluminum matrix composites (Cf/Al) with a short beam shear test method. Microstructural analysis reveals that z-pins cause minor microstructural damage including to fiber waviness and aluminum-rich regions, and interface reaction causes a strong interface between the stainless steel pin and the aluminum matrix. Z-pinned Cf/Al composites show reduced apparent interlaminar shear strength due to a change in the failure mode compared to unpinned specimens. The changed failure mode could result from decreased flexural strength due to microstructural damage as well as increased actual interlaminar shear strength. Fracture work is improved significantly with a z-pin diameter. The strong interface allows the deformation resistance of the steel pin to contribute to the crack bridging forces, which greatly enhances the interlaminar shear properties. PMID- 30275395 TI - Chemical Composition, Antioxidant Activity and alpha-Glucosidase Inhibitory Activity of Chaenomeles Speciosa from Four Production Areas in China. AB - Chaenomeles speciosa (Sweet) Nakai is a medicinal plant. Until date, there are no studies focusing on comparing the chemical profiles, antioxidant activity and alpha-glucosidase inhibitory activity of the dried fruits of C. speciosa from different production regions. In the study, we investigated the chemical components of dried fruits of C. speciosa from Yunnan, Chongqing, Zhejiang and Anhui provinces in China in relation to the antioxidant activity and alpha glucosidase inhibitory activity. C. speciosa from Yunnan had higher total flavonoid (47.92 +/- 3.79 mg/g), total polyphenol (29.15 +/- 0.29 mg/g) and polysaccharide (27.60 +/- 1.56 mg/g) contents than plants from other production areas. Samples from Yunnan, Zhejiang and Anhui (all > 3200 mg/kg) had higher free amino acid contents than those from Chongqing (2286.66 mg/kg). Oleanolic acid and ursolic acid levels were highest in samples from Zhejiang (555.98 +/- 20.88 MUg/g) and Anhui (321.06 +/- 14.64 MUg/g), respectively. C. speciosa from Chongqing had low total flavonoid, total polyphenol, polysaccharide, free amino acid, oleanolic acid and ursolic acid contents but high levels of palmitic acid (12.04 +/- 0.02 mg/g) and stearic acid (2.23 +/- 0.08 mg/g). Among four production areas, Yunnan represented the highest antioxidant activity and alpha glucosidase inhibitory activity. In addition, correlation analysis revealed that total flavonoid, total polyphenol, polysaccharide and ursolic acid were the major components responsible for the antioxidant activity of C. speciosa, while total flavonoid and polysaccharide were the main contributors for alpha-glucosidase inhibitory activity of the plant. These results would be helpful for evaluating the quality of C. speciosa in the different production areas.

AB - Polyoxymethylene (POM) fiber was treated with atmospheric dielectric barrier discharge (DBD) plasma to enhance the surface activity of the fiber and interfacial interaction with cement. The physical and chemical properties of samples with different DBD plasma treatment durations were tested and analyzed. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) revealed that the surface roughness of the sample increased significantly as a result of the DBD plasma treatment. Fourier transform infrared spectrophotometer (FTIR) and X-ray photoelectron spectroscopy (XPS) analysis showed that a large number of COH and -COOH groups were formed on the surface of the sample after DBD plasma treatment. The hydrophilicity of the POM fiber was greatly improved with the increase in the treatment duration. When the treatment duration was longer than 120 s, the fiber surface contact angle decreased from 90 degrees to 43 degrees . The DBD plasma treatment resulted in a decrease in the tensile strength of the POM fiber, but the increase in the amount of -COH and -COOH on the surface of the POM fiber and the increase in the roughness resulted in an increase in the fiber pull-out bonding strength in cement from 2.15 N to 4.68 N.

A Pragmatic Review Focused on What Could Be Improved in the Prevention and Care of Pregnancy Related AKI, in the Year Dedicated to Women and Kidney Diseases. AB - Pregnancy-related acute kidney injury (pAKI), preeclampsia (PE), and the hypertensive disorders of pregnancy are closely related conditions, which are, in turn, frequently linked to pre-existing and often non-diagnosed chronic kidney disease (CKD). The current literature and research mainly underline the effects of pregnancy complications on the offspring; this review strongly emphasizes the maternal health as well. These conditions not only negatively affect pregnancy outcomes, but have a relevant effect on the future health of affected mothers and their children. Therefore, dedicated diagnostic and follow-up programs are needed, for optimizing materno-foetal health and reducing the impact of pregnancy related problems in the mothers and in the new generations. This narrative review, performed on the occasion of the 2018 World Kidney Day dedicated to women's health, focuses on three aspects of the problem. Firstly, the risk of AKI in the hypertensive disorders of pregnancy (the risk is the highest in developing countries; however PE is the main cause of pregnancy related AKI worldwide). Secondly, the effect of AKI and the hypertensive disorders of pregnancy on the development of CKD in the mother and offspring: long-term risks are increased; the entity and the trajectories are still unknown. Thirdly, the role of CKD in the pathogenesis of AKI and the hypertensive disorders of pregnancy: CKD is a major risk factor and the most important element in the differential diagnosis; pregnancy is a precious occasion for early diagnosis of CKD. Higher awareness on the importance of AKI in pregnancy is needed to improve short and long term outcomes in mothers and children.

The dispensable nature of the B chromosome facilitates many types of genetic studies in maize. Maize lines with B chromosomes have been widely used in studies of centromere functions. Here, we discuss the maize B chromosome alongside the latest progress of B centromere activities, including centromere misdivision, inactivation, reactivation, and de novo centromere formation. The meiotic features of the B centromere, related to mini-chromosomes and the control of the size of the maize centromere, are also discussed. PMID- 30275398 TI - A Combined Dietary and Cognitive Intervention in 3-5-Year-Old Children in Indonesia: A Randomized Controlled Trial. AB - Early childhood nutritional interventions typically combine nutritional and psychosocial stimulation. Such combined interventions result in long-lasting improvements of cognitive abilities in children who are malnourished. Here, we investigated potential cognitive abilities in normally developing children in Indonesia who were, however, at risk for suboptimal cognitive development due to little psychosocial stimulation in their home environment. In a randomized controlled intervention, children of the experimental group received nutritional supplementation combined with cognitive stimulation. Pre- and post-intervention measurements included cognitive development and functioning, behavior, and mother child interaction. The experimental and control group received nutritional supplementation in the form of a fortified or unfortified milk powder, respectively. Additionally, the children and parents of the experimental group jointly engaged in daily learning activities at home and performed iPad-based tasks designed to foster cognitive abilities. The experimental group compared to the control group displayed a significantly higher increase in intelligence quotient as well as a significantly larger reduction in attentional problems after the intervention. These results indicate that low-level cognitive stimulation in combination with nutritional supplementation during early childhood can be an effective intervention that improves global cognitive functioning in healthy developing children.

AB - Commercially available autonomous photochemical reflectance index (PRI) sensors are a new development in the remote sensing field that offer novel opportunities for a deeper exploration of vegetation physiology dynamics. In this study, we evaluated the reliability of autonomous PRI sensors (SRS-PRI) developed by METER Group Inc. as proxies of light use efficiency (LUE) in an aspen (Populus tremuloides) forest stand. Before comparisons between PRI and LUE measurements were made, the optical SRS-PRI sensor pairs required calibrations to resolve diurnal and seasonal patterns properly. An offline diurnal calibration procedure was shown to account for variable sky conditions and diurnal illumination changes affecting sensor response. Eddy covariance measurements provided seasonal gross primary productivity (GPP) measures as well as apparent canopy quantum yield dynamics (alpha). LUE was derived from the ratio of GPP to absorbed photosynthetically active radiation (APAR). Corrected PRI values were derived after diurnal and midday cross-calibration of the sensor's 532 nm and 570 nm fore optics, and closely related to both LUE (R2 = 0.62, p < 0.05) and alpha (R2 = 0.72, p < 0.05). A LUE model derived from corrected PRI values showed good correlation to measured GPP (R2 = 0.77, p < 0.05), with an accuracy comparable to results obtained from an alpha driven LUE model (R2 = 0.79, p < 0.05). The automated PRI sensors proved to be suitable proxies of light use efficiency. The onset of continuous PRI sensors signifies new opportunities for explicitly examining the cause of changing PRI, LUE, and productivity over time and space. As such, this technology represents great value for the flux, remote sensing and modeling community. PMID- 30275401 TI - aP2-Cre Mediated Ablation of GHS-R Attenuates Adiposity and Improves Insulin Sensitivity during Aging. AB - Ghrelin via its receptor, the growth hormone secretagogue receptor (GHS-R), increases food intake and adiposity. The tissue-specific functions of GHS-R in peripheral tissues are mostly unknown. We previously reported that while GHS-R expression is very low in white and brown fat of young mice, expression increases during aging. To investigate whether GHS-R has cell-autonomous effects in adipose tissues, we generated aP2-Cre-mediated GHS-R knockdown mice (aP2-Cre/Ghsrf/f). We studied young (5-6 months) and old (15-17 months) aP2-Cre/Ghsrf/f mice and their age-matched controls. Interestingly, young aP2-Cre/Ghsrf/f mice had normal body weight but reduced fat; old mice showed pronounced reductions of both body weight and body fat. Calorimetry analysis revealed that aP2-Cre/Ghsrf/f mice had normal food intake and locomotor activity at both young and old age; but intriguingly, while energy expenditure was normal at young age, it was significantly increased at old age. Both young and old aP2-Cre/Ghsrf/f mice exhibited improved insulin sensitivity and glucose tolerance. Importantly, old aP2-Cre/Ghsrf/f mice maintained higher core body temperature at 4 degrees C, and showed higher expression of the thermogenic uncoupling protein 1 (UCP1) gene. The ex vivo studies further demonstrated that GHS-R deficient white adipocytes from old mice exhibit increased glucose uptake and lipolysis, promoting lipid mobilization. Despite the fact that the in vivo phenotypes of aP2-Cre/Ghsrf/f mice may not be exclusively determined by GHS-R knockdown in adipose tissues, our data support that GHS-R has cell-autonomous effects in adipocytes. The anabolic effect of GHS R in adipocytes is more pronounced in aging, which likely contributes to age associated obesity and insulin resistance. PMID- 30275403 TI - Influence of Roughness on Shear Bonding Performance of CFRP-Concrete Interface. AB - The potential of Fiber Reinforced Polymer (FRP) in the reinforcement of concrete structures has been shown in many studies and practical applications. However, few works have focused systematically on the development of quantitative criteria to measure surface roughness and relate this parameter to the bonding mechanical property. Moreover, some researchers have declared that, if the concrete interface is rougher, the bond performance between FRP and concrete will be increase, However, there is no answer to how rough the surface is. There are limited application standards for engineers to conduct in FRP reinforcement projects. This work evaluated several concrete specimens with three different strengths and six types of interface roughness. A single shear test was conducted to study the influence of surface roughness on the interfacial bonding performance of a carbon fiber-reinforced composite (CFRP)-concrete beam. The results show that, among the six interfaces, a concrete interface with the roughness of 0.44 has the best interfacial bonding performance. An interfacial appearance with the cement mortar almost cleaned away, and almost one fifth of the single coarse aggregate bared will get the best bond performance. Roughness parameters significantly influenced the effective bond length. The effective bond length of the six interfaces experienced an overall decreasing trend as the roughness increased. The bond-slip curves of concrete interfaces with roughness of 0.25-0.44 did not significantly change the rigidity within the brittle region. The rougher the interface was, the shorter the brittle region was. After entering a plasticity stage, the bond-slip curves for the six types of interfaces all declined with different slopes, and the max slip values were 0.04-0.35 mm when debonding failure occurred. PMID- 30275399 TI - Exploration of Survival Traits, Probiotic Determinants, Host Interactions, and Functional Evolution of Bifidobacterial Genomes Using Comparative Genomics. AB - Members of the genus Bifidobacterium are found in a wide-range of habitats and are used as important probiotics. Thus, exploration of their functional traits at the genus level is of utmost significance. Besides, this genus has been demonstrated to exhibit an open pan-genome based on the limited number of genomes used in earlier studies. However, the number of genomes is a crucial factor for pan-genome calculations. We have analyzed the pan-genome of a comparatively larger dataset of 215 members of the genus Bifidobacterium belonging to different habitats, which revealed an open nature. The pan-genome for the 56 probiotic and human-gut strains of this genus, was also found to be open. The accessory- and unique-components of this pan-genome were found to be under the operation of Darwinian selection pressure. Further, their genome-size variation was predicted to be attributed to the abundance of certain functions carried by genomic islands, which are facilitated by insertion elements and prophages. In silico functional and host-microbe interaction analyses of their core-genome revealed significant genomic factors for niche-specific adaptations and probiotic traits. The core survival traits include stress tolerance, biofilm formation, nutrient transport, and Sec-secretion system, whereas the core probiotic traits are imparted by the factors involved in carbohydrate- and protein-metabolism and host immunomodulations. PMID- 30275402 TI - Inflammation and the Gut-Liver Axis in the Pathophysiology of Cholangiopathies. AB - Cholangiocytes, the epithelial cells lining the bile ducts, represent the unique target of a group of progressive diseases known as cholangiopathies whose pathogenesis remain largely unknown. In normal conditions, cholangiocytes are quiescent and participate to the final bile volume and composition. Following exogenous or endogenous stimuli, cholangiocytes undergo extensive modifications of their phenotype. Reactive cholangiocytes actively proliferate and release a set of proinflammatory molecules, which act in autocrine/paracrine manner mediating the cross-talk with other liver cell types and innate and adaptive immune cells. Cholangiocytes themselves activate innate immune responses against gut-derived microorganisms or bacterial products that reach the liver via enterohepatic circulation. Gut microbiota has been implicated in the development and progression of the two most common cholangiopathies, i.e., primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC), which have distinctive microbiota composition compared to healthy individuals. The impairment of intestinal barrier functions or gut dysbiosis expose cholangiocytes to an increasing amount of microorganisms and may exacerbate inflammatory responses thus leading to fibrotic remodeling of the organ. The present review focuses on the complex interactions between the activation of innate immune responses in reactive cholangiocytes, dysbiosis, and gut permeability to bacterial products in the pathogenesis of PSC and PBC. PMID- 30275405 TI - High Throughput Manufacturing of Bacteriophages Using Continuous Stirred Tank Bioreactors Connected in Series to Ensure Optimum Host Bacteria Physiology for Phage Production. AB - Future industrial demand for large quantities of bacteriophages e.g., for phage therapy, necessitates the development of scalable Good Manufacturing Practice compliant (cGMP) production platforms. The continuous production of high titres of E coli T3 phages (1011 PFU mL-1) was achieved using two continuous stirred tank bioreactors connected in series, and a third bioreactor was used as a final holding tank operated in semi-batch mode to finish the infection process. The first bioreactor allowed the steady-state propagation of host bacteria using a fully synthetic medium with glucose as the limiting substrate. Host bacterial growth was decoupled from the phage production reactor downstream of it to suppress the production of phage-resistant mutants, thereby allowing stable operation over a period of several days. The novelty of this process is that the manipulation of the host reactor dilution rates (range 0.1-0.6 hr-1) allows control over the physiological state of the bacterial population. This results in bacteria with considerably higher intracellular phage production capability whilst operating at high dilution rates yielding significantly higher overall phage process productivity. Using a pilot-scale chemostat system allowed optimisation of the upstream phage amplification conditions conducive for high intracellular phage production in the host bacteria. The effect of the host reactor dilution rates on the phage burst size, lag time, and adsorption rate were evaluated. The host bacterium physiology was found to influence phage burst size, thereby affecting the productivity of the overall process. Mathematical modelling of the dynamics of the process allowed parameter sensitivity evaluation and provided valuable insights into the factors affecting the phage production process. The approach presented here may be used at an industrial scale to significantly improve process control, increase productivity via process intensification, and reduce process manufacturing costs through process footprint reduction. PMID- 30275404 TI - Biological and Chemical Diversity of Ascidian-Associated Microorganisms. AB - Ascidians are a class of sessile filter-feeding invertebrates, that provide unique and fertile niches harboring various microorganisms, such as bacteria, actinobacteria, cyanobacteria and fungi. Over 1000 natural products, including alkaloids, cyclic peptides, and polyketides, have been isolated from them, which display diverse properties, such as antibacterial, antifungal, antitumor, and anti-inflammatory activities. Strikingly, direct evidence has confirmed that ~8% of natural products from ascidians are actually produced by symbiotic microorganisms. In this review, we present 150 natural products from microorganisms associated with ascidians that have been reported up to 2017. PMID- 30275407 TI - Micro-Doppler Feature Extraction of Inverse Synthetic Aperture Imaging Laser Radar Using Singular-Spectrum Analysis. AB - Different from microwave radar, laser radar could be more sensitive to the micro Doppler (m-D) effect due to its wave length. This limits the application of conventional methods, such as time-frequency based approach, since the processing needs a receiver with much higher sampling frequency than microwave radar. In this paper, a micro-Doppler feature extraction algorithm is proposed for the inverse synthetic aperture imaging laser radar (ISAIL). Singular-spectrum analysis (SSA) is employed for separation and reconstruction of the micro-Doppler and rigid body signal. Clear ISAIL image is obtained by minimum entropy criteria after echo signal decomposition. After theoretical derivation, the computation efficiency and ability of the proposed method is proved by the results of simulation and real data of An-26.

AB - Four new meroterpenoids 1-4 and four new isocoumarinoids 5-8, along with five known isocoumarinoids (9-13), were isolated from the fungus Myrothecium sp. OUCMDZ-2784 associated with the salt-resistant medicinal plant, Apocynum venetum (Apocynaceae). Their structures were elucidated by means of spectroscopic analysis, X-ray crystallography, ECD spectra and quantum chemical calculations. Compounds 1-5, 7, 9 and 10 showed weak alpha-glucosidase inhibition with the IC50 values of 0.50, 0.66, 0.058, 0.20, 0.32, 0.036, 0.026 and 0.37 mM, respectively. PMID- 30275409 TI - The Implementation Process for Pharmacogenomic Testing for Cancer-Targeted Therapies. AB - Recent advances in genomic medicine have led to the availability of genomic tests that have the potential to improve population health, yet the process for obtaining these tests and getting them reimbursed by insurers has not been described. The objective of this study was to describe the process of ordering pharmacogenomic tests by interviewing providers, patients, and laboratories about cancer-related pharmacogenomic tests. We interviewed patients who were prescribed, providers who prescribed medications that should be guided by pharmacogenomic testing, and individuals from diagnostic laboratories. A total of 10 providers, 16 patients, and eight diagnostic laboratories described logistical and insurance issues relating to ordering and receiving pharmacogenomic tests and medications. We found that the process of ordering pharmacogenomic tests is time consuming, expensive, and complex. Ordering pharmacogenomic tests is quite different across institutions. Even in the same institution, multiple providers can order the test. Once the provider places the order for the pharmacogenomic test, the laboratory receives the request and usually begins testing without knowing how the test will be paid for. Next, the laboratory completes the pharmacogenomic testing and the results of the tests are reported to providers, patients, or placed directly in the medical record. In conclusion, processes related to ordering and obtaining insurance coverage for pharmacogenomic tests varies greatly across institutions and is time-consuming. PMID- 30275411 TI - 40 Years of Percutaneous Coronary Intervention: History and Future Directions. AB - The field of interventional cardiology has evolved significantly since the first percutaneous transluminal coronary angioplasty was performed 40 years ago. This evolution began with a balloon catheter mounted on a fixed wire and has progressed into bare-metal stents (BMS), first-generation drug-eluting stents (DES), second- and third-generation biodegradable polymer-based DES, and culminates with the advent of bioabsorbable stents, which are currently under development. Each step in technological advancement has improved outcomes, while new persisting challenges arise, caused by the stent scaffolds, the polymers employed, and the non-selective cytostatic and cytotoxic drugs eluted from the stents. Despite the promising technological advances made in stent technology, managing the balance between reductions in target lesion revascularization, stent thrombosis, and bleeding remain highly complex issues. This review summarizes the evolution of percutaneous coronary intervention with a focus on vascular dysfunction triggered by the non-selective drugs eluted from various stents. It also provides an overview of the mechanism of action of the drugs currently used in DES. We also discuss the efforts made in developing novel cell-selective drugs capable of inhibiting vascular smooth muscle cell (VSMC) proliferation, migration, and infiltration of inflammatory cells while allowing for complete reendothelialization. Lastly, in the era of precision medicine, considerations of patients' genetic variance associated with myocardial infarction and in-stent restenosis are discussed. The combination of personalized medicine and improved stent platform with cell-selective drugs has the potential to solve the remaining challenges and improve the care of coronary artery disease patients. PMID- 30275410 TI - Association of Uremic Toxins and Inflammatory Markers with Physical Performance in Dialysis Patients. AB - Association of higher serum levels of uremic toxins and inflammatory markers with poorer physical performance is understudied. We measured the six-minute walk test (6MWT), 10 repetition sit-to-stand test (STS-10), handgrip strength (HGS), and Human Activity Profile (HAP) questionnaire score in 90 prevalent hemodialysis patents, with low comorbidity to reduce the potential confounding of concomitant disease. Midweek pre-dialysis serum levels of asymmetric dimethyl-arginine (ADMA), beta2-microglobulin (B2M), high-sensitivity C-reactive protein (hs-CRP), indoxyl sulfate (IS), insulin-like growth factor 1 (IGF-1), interleukin 6 (IL-6), myostatin, and urea were analyzed as predictor parameters of physical performance measures in adjusted models. Serum levels of most measured toxins were not significantly related to performance, except for ADMA, which was significantly related to poorer performance in the STS-10 test (B = 0.11 +/- 0.03 s, p < 0.01). Higher hs-CRP was associated with poorer results in the 6MWT (B = -2.6 +/- 0.97 m, p < 0.01) and a lower HAP score (B = -0.36 +/- 0.14, p = 0.01). There were no other significant associations found. We conclude that inflammation may be a more important pathway to physical impediment than uremic toxemia. This suggests that there is a large physical rehabilitation potential in non-inflamed uremic patients. PMID- 30275408 TI - Roles of Mitogen-Activated Protein Kinases in Osteoclast Biology. AB - Bone undergoes continuous remodeling, which is homeostatically regulated by concerted communication between bone-forming osteoblasts and bone-degrading osteoclasts. Multinucleated giant osteoclasts are the only specialized cells that degrade or resorb the organic and inorganic bone components. They secrete proteases (e.g., cathepsin K) that degrade the organic collagenous matrix and establish localized acidosis at the bone-resorbing site through proton-pumping to facilitate the dissolution of inorganic mineral. Osteoporosis, the most common bone disease, is caused by excessive bone resorption, highlighting the crucial role of osteoclasts in intact bone remodeling. Signaling mediated by mitogen activated protein kinases (MAPKs), including extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), and p38, has been recognized to be critical for normal osteoclast differentiation and activation. Various exogenous (e.g., toll-like receptor agonists) and endogenous (e.g., growth factors and inflammatory cytokines) stimuli contribute to determining whether MAPKs positively or negatively regulate osteoclast adhesion, migration, fusion and survival, and osteoclastic bone resorption. In this review, we delineate the unique roles of MAPKs in osteoclast metabolism and provide an overview of the upstream regulators that activate or inhibit MAPKs and their downstream targets. Furthermore, we discuss the current knowledge about the differential kinetics of ERK, JNK, and p38, and the crosstalk between MAPKs in osteoclast metabolism. PMID- 30275412 TI - Healthcare Utilization in a Large Cohort of Asylum Seekers Entering Western Europe in 2015. AB - During the current period of immigration to Western Europe, national healthcare systems are confronted with high numbers of asylum seekers with largely unknown health status. To improve care taking strategies, we assessed healthcare utilization in a large, representative cohort of newly arriving migrants consisting of n = 1533 residents of a reception center in Northern Germany in 2015. Most asylum seekers were young, male adults, and the majority came from the Eastern Mediterranean region. Overall, we observed a frequency of 0.03 visits to the onsite primary healthcare ward per asylum seeker and day of camp residence (IQR 0.0-0.07, median duration of residence 38.0 days, IQR 30.0-54.25). Female asylum seekers showed higher healthcare utilization rates than their male counterparts, and healthcare utilization was particularly low in asylum seekers in their second decade of life. Furthermore, a significant correlation between time after camp entrance and healthcare utilization behavior occurred: During the first week of camp residence, 37.1 visits/100 asylum seekers were observed, opposed to only 9.5 visits/100 asylum seekers during the sixth week of camp residence. This first data on healthcare utilization in a large, representative asylum seeker cohort entering Western Europe during the current crisis shows that primary care is most needed in the first period directly after arrival. Our dataset may help to raise awareness for refugee and migrant healthcare needs and to adapt care taking strategies accordingly. PMID- 30275413 TI - Kinetics of the Solution-Mediated Polymorphic Transformation of the Novel l Carnitine Orotate Polymorph, Form-II. AB - Research studies related to the polymorphs of l-Carnitine orotate (CO), a medication used for the treatment and prevention of liver diseases, are insignificant or almost nonexistent. Accordingly, in the present study, l Carnitine orotate (CO) was prepared for investigating CO polymorphs. Here, a reactive crystallization was induced by reacting 1g of l-Carn (1 equivalent) and 0.97 g of OA (1 equivalent) in methanol (MeOH); as a result, CO form-I and CO form-II polymorphs were obtained after 1 h and 16 h of stirring, respectively. The characterization of CO polymorphs was carried out utilizing Powder X-ray diffraction (PXRD), Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA) and solid-state Nuclear Magnetic Resonance Spectroscopy (solid state CP/MAS 13C-NMR). The solution-mediated polymorphic transformation (SMPT) of CO polymorphs was investigated in MeOH at controlled temperature and fixed rotational speed. The results revealed that CO form-I is a metastable polymorph while CO form-II is a stable polymorph. From the same results, it was confirmed that CO form-I was converted to CO form-II during the polymorphic phase transformation process. Moreover, it was assessed that the increase in temperature and supersaturation level significantly promotes the rate of nucleation, as well as the rate of mass transfer of CO form-II. In addition, nucleation and mass transfer equations were employed for the quantitative determination of SMPT experimental results. Lastly, it was suggested that CO form II was more thermodynamically stable than CO form-I and that both polymorphs belong to the monotropic system. PMID- 30275415 TI - Effects of Amorphous Calcium Phosphate Administration on Dental Sensitivity during In-Office and At-Home Interventions. AB - BACKGROUND: Tooth bleaching is the most frequently employed whitening procedure in clinics. The major side effect of tooth bleaching is dental sensitivity during and after the treatment. Here, we evaluated whether the administration of amorphous calcium phosphate (ACP), during in-office and at-home procedures may impact on dental sensitivity. METHODS: Eighty patients, responding to the study requirements were enrolled according to the following criteria. Group 1 (n = 40), received in-office, 10% ACP prior to 30% professional hydrogen peroxide application. The whitening procedure continued at home using 10% carbamide peroxide with 15% ACP for 15 days. Group 2 (n = 40) received only 30% hydrogen peroxide application and continued the whitening procedures at home, using 10% carbamide hydroxide, without ACP- Casein phosphopeptides (CPP), for 15 days. Dental sensitivity was recorded with a visual analogue scale (VAS) at baseline, immediately after, and at 15 days after treatment in the two groups. RESULTS: We observed that patients receiving ACP in the bleaching mixture experienced decreased dental sensitivity (* p <= 0.05), as detected by VAS scale analysis immediately following the procedures. Patients receiving ACP-CPP during at-home procedures showed a statistically significant (*** p <= 0.0001) reduction of dental sensitivity. CONCLUSIONS: We demonstrated that ACP-CPP administration, while exerting the same whitening effects as in control subjects receiving potassium fluoride (PF), had an impact on the reduction of dental sensitivity, improving patient compliance. PMID- 30275414 TI - Converting Galactose into the Rare Sugar Talose with Cellobiose 2-Epimerase as Biocatalyst. AB - Cellobiose 2-epimerase from Rhodothermus marinus (RmCE) reversibly converts a glucose residue to a mannose residue at the reducing end of beta-1,4-linked oligosaccharides. In this study, the monosaccharide specificity of RmCE has been mapped and the synthesis of d-talose from d-galactose was discovered, a reaction not yet known to occur in nature. Moreover, the conversion is industrially relevant, as talose and its derivatives have been reported to possess important antimicrobial and anti-inflammatory properties. As the enzyme also catalyzes the keto-aldo isomerization of galactose to tagatose as a minor side reaction, the purity of talose was found to decrease over time. After process optimization, 23 g/L of talose could be obtained with a product purity of 86% and a yield of 8.5% (starting from 4 g (24 mmol) of galactose). However, higher purities and concentrations can be reached by decreasing and increasing the reaction time, respectively. In addition, two engineering attempts have also been performed. First, a mutant library of RmCE was created to try and increase the activity on monosaccharide substrates. Next, two residues from RmCE were introduced in the cellobiose 2-epimerase from Caldicellulosiruptor saccharolyticus (CsCE) (S99M/Q371F), increasing the kcat twofold. PMID- 30275416 TI - Knowledge, Attitudes, and Practices of Mothers of Preschool Children About Oral Health in Qatar: A Cross-Sectional Survey. AB - Health-related behaviors are influenced by knowledge and awareness, with oral health being no exception. It is well-known that oral diseases are influenced by social determinants. There is an association between the oral health knowledge of mothers and the status of their children's oral health. In Qatar, the knowledge and practices of oral health in preschool children have not been previously reported. The aim of this study was to assess the knowledge, attitude, and related practices of mothers of preschool children about oral health in Qatar. A total of 400 questionnaires were distributed by the principals of kindergarten to mothers of children attending 16 government kindergartens in Qatar. The questionnaire included 38 close-ended questions grouped into nine categories, addressing different aspects of knowledge and practices related to early childhood oral health. The questionnaire was constructed in English, before being translated into Arabic, which is the local language in Qatar. The questionnaire instrument was pre-tested on mothers with demographic characteristics matching the main population. These participants were not included in the main study. The questionnaire study was associated with a clinical epidemiological study to assess dental caries and enamel defects of the sampled children. The dmft caries index (decayed, missing and filled teeth) was used for that purpose according to the World Health Organization criteria. For the questionnaire administered to mothers with clinical survey variables, a binary logistic regression analysis was performed to determine the associations between the measures of oral health status (dmft, Dental index) and mothers' oral health knowledge and practices. A total of 48% mothers thought that children should have their teeth brushed from the age of three years and 42% chose younger than two years as a starting age for brushing. More than half (54%) of the mothers thought that children should not have their teeth flossed. In general, no significant statistical association was found between dmft and any other variables, except for whether or not the child had visited the dentist. Logistic regression analyses were performed to determine the association between the measures of oral health status (dmft, DI) and mothers' oral health knowledge and practices. After controlling for the other independent variables included in this model, the test of the model was not statistically significant, which indicated that none of the variables represent a significant risk for occurrence of caries. The only exception was whether or not the child had visited the dentist (odds ratio = 2.51, 95% confidence interval 1.091-5.774). Despite the existence of good knowledge of oral health care, there were deficiencies in the oral health care provided to children. This may reflect that seeking dental care is either not very important or it is challenging to obtain access to a child-friendly dentist in the public health system in Qatar. The results of this study suggest that there is a need for an oral health promotion program to fill the gaps in knowledge for mothers regarding oral health care for young children. PMID- 30275417 TI - Characterization of the Piezoresistive Effects of Silicon Nanowires. AB - Silicon nanowires (SiNWs) have received attention in recent years due to their anomalous piezoresistive (PZR) effects. Although the PZR effects of SiNWs have been extensively researched, they are still not fully understood. Herein, we develop a new model of the PZR effects of SiNWs to characterize the PZR effects. First, the resistance of SiNW is modeled based on the surface charge density. The characteristics of SiNW, such as surface charge and effective conducting area, can be estimated by using this resistance model. Then, PZR effects are modeled based on stress concentration and piezopinch effects. Stress concentration as a function of the physical geometry of SiNWs can amplify PZR effects by an order of magnitude. The piezopinch effects can also result in increased PZR effects that are at least two times greater than that of bulk silicon. Experimental results show that the proposed model can predict the PZR effects of SiNWs accurately.

AB - Epidemiology studies have investigated the association between vitamin D and the risk of sleep disorders, but the results remain controversial. Therefore, we conducted this meta-analysis with the goal of clarifying the association between vitamin D and sleep disorders risk. All relevant studies were searched using PubMed, EMBASE, and Web of Science from inception to January 2018. Pooled odds ratios (ORs) and 95% confidence interval (CIs) were calculated using a fixed effect model A total of nine studies (6 cross-sectional, 2 case-control, and 1 cohort studies) involving 9397 participants were included. By comparing the lowest verse highest levels of serum vitamin D, we found that participants with vitamin D deficiency (VDD) had a significantly increased risk of sleep disorders (OR: 1.50, 95% CI: 1.31, 1.72). Subgroup analysis showed that VDD also was associated with poor sleep quality (OR: 1.59, 95% CI: 1.23, 2.05), short sleep duration (OR: 1.74, 95% CI: 1.30, 2.32), and sleepiness (OR: 1.36, 95% CI: 1.12, 1.65). Subgroup analyses further indicated that serum 25(OH)D <20 ng/mL could significantly increase the risk of unhealthy sleep. This meta-analysis suggest that vitamin D deficiency is associated with a higher risk of sleep disorders. More high-quality cohort studies and randomized controlled trials (RCTs) are needed to verify this association. PMID- 30275419 TI - What is the Validity of Questionnaires Assessing Fruit and Vegetable Consumption in Children when Compared with Blood Biomarkers? A Meta-Analysis. AB - Fruit and vegetable consumption has been associated with improved health outcomes in children. As an extensive number of questionnaires are currently used to assess fruit and vegetable consumption, we performed a systematic review of the criterion validity of questionnaires used to estimate fruit and vegetable consumption in children, considering blood biomarkers as the reference method. Five electronic databases (MEDLINE, CINAHL, Scopus, PsycINFO, Web of Science) were searched from database inception to 23 July 2018. The search strategy used the following sets of descriptors: children; fruits and vegetables; dietary questionnaires; blood biomarkers; and validation coefficient. The search terms were adapted for use with other databases in combination with database-specific filters. Potentially eligible articles were selected independently by two reviewers, separately, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Two articles meeting the inclusion criteria were included. The main reason for study exclusion was the sample age range, which included adolescents. The pooled correlation coefficient was 0.32 (95% confidence interval: 0.24-0.40).This review provided insights into assessment methods of fruit and vegetable consumption in children. Although further studies are required, questionnaires for assessing fruit and vegetable consumption have fair criterion validity in children. PMID- 30275420 TI - Purification and Identification of Angiotensin I-Converting Enzyme Inhibitory Peptides and the Antihypertensive Effect of Chlorella sorokiniana Protein Hydrolysates. AB - Hot water was used to obtain Chlorella sorokiniana hot water extract (HWE). Subsequently, this byproduct was freeze-dried, hydrolysed at 50 degrees C using Protease N to obtain C. sorokiniana protein hydrolysates (PN-1), and then digested with a gastrointestinal enzyme (PN-1G). The inhibitory effects of the HWE and hydrolysates against angiotensin I-converting enzyme (ACE) were investigated. The soluble protein and peptide contents were 379.9 and 179.7 mg/g, respectively, for HWE and 574.8 and 332.8 mg/g, respectively, for PN-1. The IC50 values of the HWE, PN-1, and PN-1G on ACE were 1.070, 0.035, and 0.044 mg/mL, respectively. PN-1G was separated into seven fractions through size exclusion chromatography. The sixth fraction of the hydrolysate had a molecular weight between 270 and 340 Da, and the lowest IC50 value on ACE was 0.015 mg/mL. The amino acid sequences of the ACE-inhibitory peptides were Trp-Val, Val-Trp, Ile Trp, and Leu-Trp, of which the IC50 values were 307.61, 0.58, 0.50, and 1.11 uMU, respectively. Systolic blood pressure and diastolic blood pressure were reduced 20 and 21 mm Hg, respectively, in spontaneously hypertensive rats after 6 h of oral administration with a dose of 171.4 mg PN-1 powder/kg body weight. PMID- 30275421 TI - How Eliminating Malaria May Also Prevent Iron Deficiency in African Children. AB - Malaria and iron deficiency are common among children living in sub-Saharan Africa. Several studies have linked a child's iron status to their future risk of malaria infection; however, few have examined whether malaria might be a cause of iron deficiency. Approximately a quarter of African children at any one time are infected by malaria and malaria increases hepcidin and tumor necrosis factor alpha concentrations leading to poor iron absorption and recycling. In support of a hypothetical link between malaria and iron deficiency, studies indicate that the prevalence of iron deficiency in children increases over a malaria season and decreases when malaria transmission is interrupted. The link between malaria and iron deficiency can be tested through the use of observational studies, randomized controlled trials and genetic epidemiology studies, each of which has its own strengths and limitations. Confirming the existence of a causal link between malaria infection and iron deficiency would readjust priorities for programs to prevent and treat iron deficiency and would demonstrate a further benefit of malaria control. PMID- 30275423 TI - Effects of Inoculation on the Pearlitic Gray Cast Iron with High Thermal Conductivity and Tensile Strength. AB - With the aim of improving the thermal conductivity and tensile strength of pearlitic gray cast iron, the influence of inoculation on structure and properties was experimentally investigated. Three group of irons with similar compositions were inoculated by Zr-FeSi, Sr-FeSi, and SiC inoculants, respectively. The metallographic analysis was used to measure the maximum graphite length, primary dendrites amount and eutectic colonies counts. For a certain carbon equivalent, it was confirmed that the thermal conductivity of pearlitic gray cast iron has a direct correlation with the maximum graphite length while the tensile strength was influenced mainly by the primary dendrites amount. The optimal structure and highest thermal conductivity and tensile strength were obtained by Sr-FeSi inoculant. MnS particles act a pivotal part in modifying the structure of gray cast iron. It was found that providing nucleation sites both for graphite and primary austenite is important to promote the thermal conductivity and strength. However, excessive nuclei (MnS particles) results in shorter graphite flakes and thus the depressive growth of primary dendrites. PMID- 30275422 TI - Hepatoprotective Effect of Loquat Leaf Flavonoids in PM2.5-Induced Non-Alcoholic Fatty Liver Disease via Regulation of IRs-1/Akt and CYP2E1/JNK Pathways. AB - Ambient air particulate matter (PM) represents a class of heterogeneous substances present in polluted air, which contains many harmful components. Exposure to ambient particulate matter in fine rages (PM2.5) is associated with non-alcoholic fatty liver disease (NAFLD). Loquat Leaf possesses pharmacological actions on NAFLD. As the main biological active ingredients, the potential therapeutic role of total flavonoids (TF) isolated from Loquat Leaf in PM2.5 induced NAFLD model remains unclear. The present study was designed to explore the hepatoprotective effect of TF in PM2.5-induced NAFLD mice with its related mechanisms of action. Mice were exposed to PM2.5 to induce NAFLD, and body weight, the ratio of liver to body weight, and blood lipids increased significantly compared with the control group. It was found that TF significantly reduced the above parameters in PM2.5-induced NAFLD mice. TF treatment alleviated oxidative stress by preventing the accumulation of oxidative product malondialdehyde (MDA) and by strengthening the anti-oxidative capacity of superoxide dismutase (SOD). TF was also found to reduce the alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activity in the PM2.5 group. In addition, TF repaired the PM2.5-induced decline of insulin receptor substrate-1 (IRs-1) and protein kinase B (Akt) phosphorylation. Meanwhile, the data showed TF suppressed the expression of cytochrome P450 2E1(CYP2E1) and the phosphorylation of c-jun N-terminal kinase (JNK) in PM2.5-induced NAFLD. Taken together, these findings show that TF alleviate PM2.5-induced NAFLD via regulation of IRs-1/Akt and CYP2E1/JNK pathways, which may have potential for further development as novel therapeutic agents for NAFLD. PMID- 30275424 TI - Developing Lignosulfonate-Based Activated Carbon Fibers. AB - In this study, electrospinning technology, physical activation, and carbonization processing were applied to produce lignosulfonate-based activated carbon fibers. The porous structure of the produced lignosulfonate-based activated carbon fibers primarily contained mesopores and a relatively small amount of micropores. Moreover, insufficient carbonization caused fiber damage during CO2 activation. The weight loss rate and specific surface area increased with increase in carbonization time, and products with carbonization temperatures of 700 degrees C were of higher quality than those with other temperatures. Moreover, the two step carbonization process provided fibers with improved quality because of a low weight loss rate, improved processing, and high surface area. Lignosulfonate based activated carbon fibers can be used as a highly efficient adsorption and filtration material, and further development of its applications would be valuable. PMID- 30275425 TI - Stable Logic Operation of Fiber-Based Single-Walled Carbon Nanotube Transistor Circuits Toward Thread-Like CMOS Circuitry. AB - A fiber-based single-walled carbon nanotube (SWCNT) thin-film-transistor (TFT) has been proposed. We designed complementary SWCNT TFT circuit based on SPICE simulations, with device parameters extracted from the fabricated fiber-based SWCNT TFTs, such as threshold voltage, contact resistance, and off-/gate-leakage current. We fabricated the SWCNTs CMOS inverter circuits using the selective passivation and n-doping processes on a fiber substrate. By comparing the simulation and experimental results, we could enhance the circuit's performance by tuning the threshold voltage between p-type and n-type TFTs, reducing the source/drain contact resistance and off current level, and maintaining a low output capacitance of the TFTs. Importantly, it was found that the voltage gain, output swing range, and frequency response of the fiber-based inverter circuits can be dramatically improved. PMID- 30275426 TI - Fabricating a Novel Intragranular Microstructure for Al2O3/GdAlO3 Ceramic Composites. AB - In order to make the embryonic form of intragranular structure, the Al2O3/GdAlO3 system was selected due to its excellent mechanical properties. Gd2O3 and Al(NO3)3.9H2O were used as the starting materials. A co-precipitation method was used for the preparation of fine ceramics and applied to synthesize the nano powder of GdAlO3 firstly. Then, the nano-powder of GdAlO3 was mixed with the precipitates by the second co-precipitation method. After drying and calcination, the compound powder with eutectic composition (77 mol % Al3+-23 mol % Gd3+) was fast sintered by using the spark plasma sintering technique. The results revealed that the phases of the sintered samples were Al2O3 and GdAlO3. The phases showed a homogeneous and interlaced distribution. All the matrix grains were submicron. The sizes of the intragranular structures were between 50 nm and 150 nm. Therefore, the intragranular structure displayed a novel mixture of nanometer submicron and submicron-submicron types. The different intragranular structures all changed the fracture modes of Al2O3 grains from intergranular fracture to transgranular fracture. PMID- 30275427 TI - Encapsulation of Rat Bone Marrow Derived Mesenchymal Stem Cells in Alginate Dialdehyde/Gelatin Microbeads with and without Nanoscaled Bioactive Glass for In Vivo Bone Tissue Engineering. AB - Alginate dialdehyde (ADA), gelatin, and nano-scaled bioactive glass (nBG) particles are being currently investigated for their potential use as three dimensional scaffolding materials for bone tissue engineering. ADA and gelatin provide a three-dimensional scaffold with properties supporting cell adhesion and proliferation. Combined with nanocristalline BG, this composition closely mimics the mineral phase of bone. In the present study, rat bone marrow derived mesenchymal stem cells (MSCs), commonly used as an osteogenic cell source, were evaluated after encapsulation into ADA-gelatin hydrogel with and without nBG. High cell survival was found in vitro for up to 28 days with or without addition of nBG assessed by calcein staining, proving the cell-friendly encapsulation process. After subcutaneous implantation into rats, survival was assessed by DAPI/TUNEL fluorescence staining. Hematoxylin-eosin staining and immunohistochemical staining for the macrophage marker ED1 (CD68) and the endothelial cell marker lectin were used to evaluate immune reaction and vascularization. After in vivo implantation, high cell survival was found after 1 week, with a notable decrease after 4 weeks. Immune reaction was very mild, proving the biocompatibility of the material. Angiogenesis in implanted constructs was significantly improved by cell encapsulation, compared to cell free beads, as the implanted MSCs were able to attract endothelial cells. Constructs with nBG showed higher numbers of vital MSCs and lectin positive endothelial cells, thus showing a higher degree of angiogenesis, although this difference was not significant. These results support the use of ADA/gelatin/nBG as a scaffold and of MSCs as a source of osteogenic cells for bone tissue engineering. Future studies should however improve long term cell survival and focus on differentiation potential of encapsulated cells in vivo. PMID- 30275428 TI - Effect of Arthrospira (Spirulina) maxima Supplementation and a Systematic Physical Exercise Program on the Body Composition and Cardiorespiratory Fitness of Overweight or Obese Subjects: A Double-Blind, Randomized, and Crossover Controlled Trial. AB - : Excess weight and obesity are major risk factors for many chronic diseases, and weight-loss interventions often include systematic exercise and nutritional supplements. The purpose of this study was to determine the independent/synergistic effects of Arthrospira (Spirulina) maxima supplementation (six weeks, 4.5 g.day-1) and a systematic physical exercise program (six weeks, twice weekly) on the body composition and cardiorespiratory fitness of overweight and obese subjects. To achieve this, 27 overweight and 25 obese sedentary male subjects were assigned to four interventions through a randomized double-blind, crossover controlled trial: A physical exercise program, with (SE) or without (Ex) Spirulina maxima; or no-exercise program, with (Sm) and without (C) Spirulina maxima. The body composition and cardiorespiratory fitness parameters were taken during a maximum intensity test. As compared to the C group, the body fat percentage of the SE, Sm and Ex groups was reduced (p < 0.05), while their maximal oxygen uptake improved (r = -0.40), and obese subjects benefited more significantly. Weight loss, the time to reach fatigue and the onset of blood lactate accumulation were improved in both of the Spirulina maxima supplemented groups, regardless of the subjects' body weight. Spirulina maxima supplementation synergistically improves the effects of systematic exercise on body composition and cardiorespiratory fitness parameters in overweight, but mostly in individuals with obesity. TRIAL REGISTRATION: Clinical Trials, NCT02837666. Registered 19 July 2016. PMID- 30275429 TI - Preliminary Study to Determinate the Effect of the Rearing Managements Applied during Heifers' Whole Life on Carcass and Flank Steak Quality. AB - The aim of this study was to investigate the impact of rearing managements applied during a heifers' whole life on the carcass and flank steak (rectus abdominis) meat traits. For this study, rearing managements applied on 96 heifers were identified by conducting surveys in farms. A heifers' whole life was divided into three key periods: Pre-weaning, growth, and fattening. The combination of the rearing factors applied during the heifers' whole life allowed us to characterize several rearing managements. Among them, four have been studied in depth. The main results displayed that the carcass traits were more sensitive to the rearing managements than the flank steak traits. The different managements considered had an impact on the weight, the dressing percentage and the conformation score of the carcass. Whereas, they had no impact on the sensory descriptors, the sheer force and the color of the flank steak. This study showed that the variations observed for carcass and meat traits could not be explained by the variation of only one rearing factor but could be explained by many rearing factors characterizing the rearing management applied. Finally, this study demonstrated that it was possible to improve carcass traits without deteriorating meat traits. PMID- 30275430 TI - Enhancing Bioactive Antioxidants' Extraction from "Horchata de Chufa" By Products. AB - During the production of a traditional drink produced from the tubers of Cyperus esculentus L. also known as "horchata de chufa," a high quantity of by-products are generated. These by-products are rich with valuable biological compounds, hence, there is a need to report their extraction conditions for further use in food production as raw materials. Therefore, the objective of this study was to evaluate and improve the conventional extraction process, applied for recovery of phenolic compounds, total flavonoids, and total antioxidant capacity from the by products. Independent variables for extraction were: (i) Solvent type (mixtures of ethanol-water (v/v) at 0%, 25% and 50%); (ii) temperature (40, 50 and 60 degrees C), and (iii) extraction time (1, 2 and 3 h). The obtained results showed that solvent type, temperature, and time significantly influenced (p < 0.05) all investigated parameters. The highest content of total polyphenols (16.02 mg GAE/100 g of dry matter; d.m.), and total flavonoids (30.09 mg CE/100 g d.m.) was achieved by ethanol at 25% (v/v), after 3 h of extraction with temperatures of 60 degrees C and 50 degrees C, respectively. The highest value of antioxidant capacity (1759.81 uM Trolox equivalents/g d.m.) was observed with 50% aqueous ethanol (v/v), at 60 degrees C, and 3 h of extraction. From the obtained results, it can be concluded that the by-products of "Horchata de Chufa" are an important source of antioxidant bioactive compounds. PMID- 30275432 TI - Polymerase Chain Reaction (PCR) as a Potential Point of Care Laboratory Test for Leprosy Diagnosis-A Systematic Review. AB - Leprosy is an infectious disease caused by Mycobacterium leprae and mainly affects skin, peripheral nerves, and eyes. Suitable tools for providing bacteriological evidence of leprosy are needed for early case detection and appropriate therapeutic management. Ideally these tools are applicable at all health care levels for the effective control of leprosy. This paper presents a systematic review analysis in order to investigate the performance of polymerase chain reaction (PCR) vis-a-vis slit skin smears (SSS) in various clinical settings and its potential usefulness as a routine lab test for leprosy diagnosis. Records of published journal articles were identified through PubMed database search. Twenty-seven articles were included for the analysis. The evidence from this review analysis suggests that PCR on skin biopsy is the ideal diagnostic test. Nevertheless, PCR on SSS samples also seems to be useful with its practical value for application, even at primary care levels. The review findings also indicated the necessity for improving the sensitivity of PCR and further research on specificity in ruling out other clinical conditions that may mimic leprosy. The M. leprae-specific repetitive element (RLEP) was the most frequently-used marker although its variable performance across the clinical sites and samples are a matter of concern. Undertaking further research studies with large sample numbers and uniform protocols studied simultaneously across multiple clinical sites is recommended to address these issues. PMID- 30275431 TI - Microplastics in Sediment and Surface Water of West Dongting Lake and South Dongting Lake: Abundance, Source and Composition. AB - Microplastic pollution was investigated in sediment and surface water in West Dongting Lake and South Dongting Lake for the first time. The abundance of microplastics ranged from 616.67 to 2216.67 items/m3 and 716.67 to 2316.67 items/m3 in the lakeshore surface water of West Dongting Lake and South Dongting Lake, respectively. The highest levels of microplastic pollution were found in the lakes' outlets. In the lake center sites of the West Dongting Lake and South Dongting Lake, the abundance of microplastics ranged from 433.33 to 1500 items/m3 and 366.67 to 1566.67 items/m3, respectively. Meanwhile, the study found that in lakeshore sediment of West Dongting Lake and South Dongting Lake, microplastic concentrations ranged from 320 to 480 items/m3 and 200-1150 items/m3. Polystyrene (PS) and polyethylene terephthalate (PET) were most common in the surface water and sediment samples, respectively. In addition, we suggest that the effects of polymer types in microplastics should be taken into account when considering abundance. This study can provide valuable points of reference to better understanding microplastic pollution in inland freshwater areas. PMID- 30275433 TI - Reputation-Aware Recruitment and Credible Reporting for Platform Utility in Mobile Crowd Sensing with Smart Devices in IoT. AB - The Internet of things (IoT) comprises a huge collection of electronic devices connected to the Internet to ensure the dependable exchange of sensing information. It involves mobile workers (MWs) who perform various activities to support enormous online services and applications. In mobile crowd sensing (MCS), a massive amount of sensing data is also generated by smart devices. Broadly, in the IoT, verifying the credibility and truthfulness of MWs' sensing reports is needed for MWs to expect attractive rewards. MWs are recruited by paying monetary incentives that must be awarded according to the quality and quantity of the task. The main problem is that MWs may perform false reporting by sharing low quality reported data to reduce the effort required. In the literature, false reporting is improved by hiring enough MWs for a task to evaluate the trustworthiness and acceptability of information by aggregating the submitted reports. However, it may not be possible due to budget constraints, or when malicious reporters are not identified and penalized properly. Recruitment is still not a refined process, which contributes to low sensing quality. This paper presents Reputation, Quality-aware Recruitment Platform (RQRP) to recruit MWs based on reputation for quality reporting with the intention of platform profit maximization in the IoT scenario. RQRP comprises two main phases: filtration in the selection of MWs and verifying the credibility of reported tasks. The former is focused on the selection of suitable MWs based on different criteria (e.g., reputation, bid, expected quality, and expected platform utility), while the latter is more concerned with the verification of sensing quality, evaluation of reputation score, and incentives. We developed a testbed to evaluate and analyze the datasets, and a simulation was performed for data collection scenario from smart sensing devices. Results proved the superiority of RQRP against its counterparts in terms of truthfulness, quality, and platform profit maximization. To the best of our knowledge, we are the first to study the impact of truthful reporting on platform utility. PMID- 30275435 TI - Allogeneic CAR-T Cells: More than Ease of Access? AB - Patient derived anti-CD19 chimeric antigen receptor-T (CAR-T) cells are a powerful tool in achieving a complete remission in a range of B-cell malignancies, most notably B-acute lymphoblastic leukaemia (B-ALL) and diffuse large B-cell lymphoma (DLBCL). However, there are limitations, including inability to manufacture CAR-T cells from the patient's own T cells, disease progression and death prior to return of engineered cells. T cell dysfunction is known to occur in cancer patients, and several groups have recently described differences in CAR-T cells generated from chronic lymphocytic leukaemia (CLL) patients compared with those from a healthy donor. This is thought to contribute to the low response rate in this disease group. Healthy donor, gene-edited CAR-T cells which do not require human leucocyte antigen (HLA) matching have the potential to provide an 'off the shelf' product, overcoming the manufacturing difficulties of producing CAR-T cells for each individual patient. They may also provide a more functional, potent product for malignancies such as CLL, where T cell dysfunction is common and frequently cannot be fully reversed during the manufacturing process. Here we review the potential benefits and obstacles for healthy donor, allogeneic CAR-T cells. PMID- 30275436 TI - Validation of an Improved Statistical Theory for Sea Surface Whitecap Coverage Using Satellite Remote Sensing Data. AB - The whitecap coverage at the sea surface is affected by the ratio of kinetic energy to potential energy, theta, the wave spectrum width parameter, rho, and other factors. This paper validates an improved statistical theory for surface whitecap coverage. Based on the theoretical analysis, we find that the whitecap coverage is more sensitive to rho than to theta, and the improved statistical theory for surface whitecap coverage is suitable in regions of rough winds and waves. The satellite-derived whitecap coverage data in the westerly wind zone is used to validate the improved theory. The comparison between the results from theory and observations displays a better performance from the improved theory relative to the other methods tested. PMID- 30275434 TI - Implication of Trimethylamine N-Oxide (TMAO) in Disease: Potential Biomarker or New Therapeutic Target. AB - Trimethylamine N-oxide (TMAO) is a molecule generated from choline, betaine, and carnitine via gut microbial metabolism. The plasma level of TMAO is determined by several factors including diet, gut microbial flora, drug administration and liver flavin monooxygenase activity. In humans, recent clinical studies evidence a positive correlation between elevated plasma levels of TMAO and an increased risk for major adverse cardiovascular events. A direct correlation between increased TMAO levels and neurological disorders has been also hypothesized. Several therapeutic strategies are being explored to reduce TMAO levels, including use of oral broad spectrum antibiotics, promoting the growth of bacteria that use TMAO as substrate and the development of target-specific molecules. Despite the accumulating evidence, it is questioned whether TMAO is the mediator of a bystander in the disease process. Thus, it is important to undertake studies to establish the role of TMAO in human health and disease. In this article, we reviewed dietary sources and metabolic pathways of TMAO, as well as screened the studies suggesting possible involvement of TMAO in the etiology of cardiovascular and neurological disorders, underlying the importance of TMAO mediating inflammatory processes. Finally, the potential utility of TMAO as therapeutic target is also analyzed. PMID- 30275437 TI - A Swarming Approach to Optimize the One-Hop Delay in Smart Driving Inter-Platoon Communications. AB - Multi-platooning is an important management strategy for autonomous driving technology. The backbone vehicles in a multi-platoon adopt the IEEE 802.11 distributed coordination function (DCF) mechanism to transmit vehicles' kinematics information through inter-platoon communications, and then forward the information to the member vehicles through intra-platoon communications. In this case, each vehicle in a multi-platoon can acquire the kinematics information of other vehicles. The parameters of DCF, the hidden terminal problem and the number of neighbors may incur a long and unbalanced one-hop delay of inter-platoon communications, which would further prolong end-to-end delay of inter-platoon communications. In this case, some vehicles within a multi-platoon cannot acquire the emergency changes of other vehicles' kinematics within a limited time duration and take prompt action accordingly to keep a multi-platoon formation. Unlike other related works, this paper proposes a swarming approach to optimize the one-hop delay of inter-platoon communications in a multi-platoon scenario. Specifically, the minimum contention window size of each backbone vehicle is adjusted to enable the one-hop delay of each backbone vehicle to get close to the minimum average one-hop delay. The simulation results indicate that, the one-hop delay of the proposed approach is reduced by 12% as compared to the DCF mechanism with the IEEE standard contention window size. Moreover, the end-to-end delay, one-hop throughput, end-to-end throughput and transmission probability have been significantly improved. PMID- 30275438 TI - Fence Angioplasty Prevents Narrowing of Venous Anastomosis in Solitary Pancreas Transplant. AB - BACKGROUND Graft thrombosis is the leading cause of early graft failure in pancreas transplants. Direct anastomosis grafting of the portal vein to the iliac vein or vena cava generally appears narrowed on postoperative computed tomography (CT) scans. However, modification of surgical techniques may prevent venous narrowing, which also prevents thrombosis-related graft failure. MATERIAL AND METHODS We performed 31 solitary pancreas transplants since 2015. Retrospective analysis of these patients was performed. RESULTS Fence angioplasty was applied in the final 12 cases, and no technical failures or early graft losses occurred in these cases. Three graft losses, including 2 immunologic losses and 1 patient death with functioning graft, occurred after at least postoperative 4 months. The venous anastomoses were evaluated via intraoperative Doppler ultrasound and postoperative CT scans. Intraoperative Doppler ultrasound revealed improved spectral waves of venous anastomoses in the fence group (monophasic spectral wave, 42.9% vs. 0%, p=0.017). The fence-graft applied group had no cases of narrowing, whereas the non-fence group had high narrowing rates on CT scans (84.2% vs. 0%, p<0.001). Furthermore, with less use of postoperative heparin, postoperative bleeding rates were lower in the fence group (36% vs. 0%, p=0.026). CONCLUSIONS Fence angioplasty is a definitive method for avoiding venous anastomotic stenosis and preventing graft failure due to thrombosis. PMID- 30275439 TI - Three-Dimensional Volume Imaging to Increase the Accuracy of Surgical Management in a Case of Recurrent Chordoma of the Clivus. AB - BACKGROUND The clivus is a depression in the anterior occipital bone of the skull base, posterior to the dorsum sellae, at the junction with the sphenoid bone. Chordoma is a rare tumor arising from embryonic remnants of the notochord and can be locally aggressive with a tendency to recur. The optimal management of this rare tumor remains controversial. A report of a case of recurrent chordoma of the clivus is presented to illustrate the value of volumetric three-dimensional (3-D) reconstruction with computed tomography (CT) and magnetic resonance imaging (MRI) to determine optimal surgical management. CASE REPORT A 53-year-old man presented with pain in the right orbital cavity, right proptosis, swelling of the right cheek, and bilateral loss of vision. He also had adrenal insufficiency. CT and contrast-enhanced (gadolinium) T1-weighted MRI with multiplanar acquisition were performed with volumetric 3-D reconstruction of the tumor, to increase the chances of treatment success. Surgical resection was performed to remove the tumor and reduce the risk of recurrence. Histology of the tumor was consistent with chordoma, supported by positive immunohistochemical staining for S-100 and epithelial membrane antigen (EMA). CONCLUSIONS This report highlighted the value of 3-D volume imaging in the diagnosis and treatment planning in a rare case of recurrent chordoma of the clivus. Analysis of tumor volume may be an indicator of the efficacy of surgery, complementing the Response Evaluation Criteria In Solid Tumors (RECIST) system and as a valuable tool to predict treatment outcome. PMID- 30275440 TI - DNA Repair Gene (XPD, XRCC4, and XRCC1) Polymorphisms in Patients with Endometrial Hyperplasia: A Pilot Study. AB - BACKGROUND In this study, we aimed to evaluate the association between endometrial hyperplasia and DNA repair gene (XPD, XRCC4, and XRCC1) polymorphisms. MATERIAL AND METHODS There were 114 cases enrolled in the study in 4 groups: simple endometrial hyperplasia (SH) (Group 1), complex endometrial hyperplasia without atypia (CH) (Group 2), complex atypical endometrial hyperplasia (CAH) (Group 3), and normal endometrium (NE) (Group 4). Of these cases, 37 cases had SH, 36 cases had CH, 16 cases had CAH, and 25 cases had NE. To evaluate an association between atypia and DNA repair genes, we consider a group that included both SH and CH, the endometrial hyperplasia without atypia cases (Group 5). Genomic DNA was isolated from paraffin-embedded endometrial tissue collected from the Pathology Department of Gaziantep University Medical School. Polymerase chain reaction (PCR) and/or restriction fragment length polymorphism (RFLP) method was used for evaluating of XPD (-751), XRCC4 (-1394 and a variable number of tandem repeats in intron 3), and XRCC1 (-399) genes. RESULTS We observed a notable distinction in patients having endometrial hyperplasia without atypia (the SH+CH group) and the CAH group in terms of XPD ( 751) gene polymorphisms. A notable contrast was observed in patients with endometrial hyperplasia without atypia (the SH+CH group) and the NE group in terms of XRCC4 (VNTR intron 3) polymorphisms (P=0.026, P=0.018, respectively). CONCLUSIONS It was evident the DNA repair gene XPD and XRCC4 polymorphisms had a role in the pathophysiology of endometrial hyperplasia. PMID- 30275441 TI - Metformin Increases Cardiac Rupture After Myocardial Infarction via the AMPK MTOR/PGC-1alpha Signaling Pathway in Rats with Acute Myocardial Infarction. AB - BACKGROUND Cardiac rupture often occurs after acute myocardial infarction due to complex and unclear pathogenesis. This study investigated whether metformin increases the incidence of cardiac rupture after myocardial infarction through the AMPK-MTOR/PGC-1alpha signaling pathway. MATERIAL AND METHODS An acute myocardial infarction (MI) mouse model was established. A series of experiments involving RT-qPCR, Western blot, TUNEL staining, and Masson staining were performed in this study. RESULTS Myocardial infarction occurred, resulting in the cardiac rupture, and the expression level of PGC-1alpha increased in the cardiac myocardium. Meanwhile, the proportion of myocardial NT-PGC-1alpha/PGC-1alpha decreased. The expression level of myocardial PGC-1alpha in MI mice with cardiac rupture after MI was significantly higher than that in the mice without cardiac rupture, and the ratio of myocardial NT-PGC-1alpha/PGC-1alpha was low. In addition, increasing the dose of metformin significantly increased the incidence of cardiac rupture after myocardial infarction in MI mice. High-dose metformin caused cardiac rupture in MI mice. Moreover, high-dose metformin (Met 2.0 nM) reduces the proportion of NT-PGC-1alpha/PGC-1alpha in primary cardiomyocytes of SD mice (SD-NRVCs [Neonatal rat ventricular cardiomyocytes]), and its effect was inhibited by Compound C (AMPK inhibitor). Further, after 3 days of treatment with high-dose metformin in MI mice, myocardial fibrin synthesis decreased and fibrosis was significantly inhibited. Meanwhile, cardiomyocyte apoptosis increased significantly. With the increase in metformin concentration, the expression level of myocardial LC3b gradually increased in MI mice, suggesting that metformin enhances the autophagy of cardiomyocytes. CONCLUSIONS These results suggest that metformin increases cardiac rupture after myocardial infarction through the AMPK-MTOR/PGC-1alpha signaling pathway.

AB - The observation of chemical reactions on the time scale of the motion of electrons and nuclei has been made possible by lasers with ever shortened pulse lengths. Superfluid helium represents a special solvent that permits the synthesis of novel classes of molecules that have eluded dynamical studies so far. However, photoexcitation inside this quantum solvent triggers a pronounced response of the solvation shell, which is not well understood. Here, we present a mechanistic description of the solvent response to photoexcitation of indium (In) dopant atoms inside helium nanodroplets (HeN), obtained from femtosecond pump probe spectroscopy and time-dependent density functional theory simulations. For the In-HeN system, part of the excited state electronic energy leads to expansion of the solvation shell within 600 fs, initiating a collective shell oscillation with a period of about 30 ps. These coupled electronic and nuclear dynamics will be superimposed on intrinsic photoinduced processes of molecular systems inside helium droplets.

AB - Quantum ground states that arise at atomically controlled oxide interfaces provide an opportunity to address key questions in condensed matter physics, including the nature of two-dimensional metallic behaviour often observed adjacent to superconductivity. At the superconducting LaAlO3/SrTiO3 interface, a metallic ground state emerges upon the collapse of superconductivity with field effect gating and is accompanied with a pseudogap. Here we utilize independent control of carrier density and disorder of the interfacial superconductor using dual electrostatic gates, which enables the comprehensive examination of the electronic phase diagram approaching zero temperature. We find that the pseudogap corresponds to precursor pairing, and the onset of long-range phase coherence forms a two-dimensional superconducting dome as a function of the dual-gate voltages. The gate-tuned superconductor-metal transitions are driven by macroscopic phase fluctuations of Josephson coupled superconducting puddles.

AB - TGFbeta1 has been implicated in regulating functional aspects of several distinct immune cell populations including central nervous system (CNS) resident microglia. Activation and priming of microglia have been demonstrated to contribute to the progression of neurodegenerative diseases and, thus, underlie stringent control by endogenous regulatory factors including TGFbeta1. Here, we demonstrate that deletion of Tgfbr2 in adult postnatal microglia does neither result in impairment of the microglia-specific gene expression signatures, nor is microglial survival and maintenance affected. Tgfbr2-deficient microglia were characterised by distinct morphological changes and transcriptome analysis using RNAseq revealed that loss of TGFbeta signalling results in upregulation of microglia activation and priming markers. Moreover, protein arrays demonstrated increased secretion of CXCL10 and CCL2 accompanied by activation of immune cell signalling as evidenced by increased phosphorylation of TAK1. Together, these data underline the importance of microglial TGFbeta signalling to regulate microglia adaptive changes. PMID- 30275446 TI - Strong coupling and induced transparency at room temperature with single quantum dots and gap plasmons. AB - Coherent coupling between plasmons and transition dipole moments in emitters can lead to two distinct spectral effects: vacuum Rabi splitting at strong coupling strengths, and induced transparency (also known as Fano interference) at intermediate coupling strengths. Achieving either strong or intermediate coupling between a single emitter and a localized plasmon resonance has the potential to enable single-photon nonlinearities and other extreme light-matter interactions, at room temperature and on the nanometer scale. Both effects produce two peaks in the spectrum of scattering from the plasmon resonance, and can thus be confused if scattering measurements alone are performed. Here we report measurements of scattering and photoluminescence from individual coupled plasmon-emitter systems that consist of a single colloidal quantum dot in the gap between a gold nanoparticle and a silver film. The measurements unambiguously demonstrate weak coupling (the Purcell effect), intermediate coupling (Fano interference), and strong coupling (Rabi splitting) at room temperature. PMID- 30275445 TI - Analysis of chromatin accessibility uncovers TEAD1 as a regulator of migration in human glioblastoma. AB - The intrinsic drivers of migration in glioblastoma (GBM) are poorly understood. To better capture the native molecular imprint of GBM and its developmental context, here we isolate human stem cell populations from GBM (GSC) and germinal matrix tissues and map their chromatin accessibility via ATAC-seq. We uncover two distinct regulatory GSC signatures, a developmentally shared/proliferative and a tumor-specific/migratory one in which TEAD1/4 motifs are uniquely overrepresented. Using ChIP-PCR, we validate TEAD1 trans occupancy at accessibility sites within AQP4, EGFR, and CDH4. To further characterize TEAD's functional role in GBM, we knockout TEAD1 or TEAD4 in patient-derived GBM lines using CRISPR-Cas9. TEAD1 ablation robustly diminishes migration, both in vitro and in vivo, and alters migratory and EMT transcriptome signatures with consistent downregulation of its target AQP4. TEAD1 overexpression restores AQP4 expression, and both TEAD1 and AQP4 overexpression rescue migratory deficits in TEAD1-knockout cells, implicating a direct regulatory role for TEAD1-AQP4 in GBM migration. PMID- 30275447 TI - Efficient photocatalytic hydrogen evolution with ligand engineered all-inorganic InP and InP/ZnS colloidal quantum dots. AB - Photocatalytic hydrogen evolution is a promising technique for the direct conversion of solar energy into chemical fuels. Colloidal quantum dots with tunable band gap and versatile surface properties remain among the most prominent targets in photocatalysis despite their frequent toxicity, which is detrimental for environmentally friendly technological implementations. In the present work, all-inorganic sulfide-capped InP and InP/ZnS quantum dots are introduced as competitive and far less toxic alternatives for photocatalytic hydrogen evolution in aqueous solution, reaching turnover numbers up to 128,000 based on quantum dots with a maximum internal quantum yield of 31%. In addition to the favorable band gap of InP quantum dots, in-depth studies show that the high efficiency also arises from successful ligand engineering with sulfide ions. Due to their small size and outstanding hole capture properties, sulfide ions effectively extract holes from quantum dots for exciton separation and decrease the physical and electrical barriers for charge transfer. PMID- 30275449 TI - Engineering functional BMP-2 expressing teratoma-derived fibroblasts for enhancing osteogenesis. AB - Bone morphogenetic protein 2 (BMP-2) is considered an effective growth factor for bone formation, and is used for making osteo-inductive scaffolds, but the related clinical investigations have shown low success rates. In this study, we genetically manipulated teratoma-derived fibroblast (TDF) cells by simultaneous introduction of BMP-2 and herpes simplex virus-thymidine kinase (HSV-tk) encoding genes. Self-production of BMP-2 in TDF cells strongly enhanced the alkaline phosphatase (ALP) activity, calcium content, and elevated the mRNA expression of osteogenic marker genes during in vitro osteogenesis. The bone formation volume was also remarkably enhanced in calvarial and femoral critical-size defect models. Ganciclovir (GCV) treatment induced apoptosis in TDF cells co-expressing HSV-tk and BMP-2, implying that HSV-tk suicide gene can modulate the side-effects of stem cell therapy, e.g., development of uncontrollable teratoma and tumor formation. Altogether, our findings revealed a safe and highly efficient technique with potential therapeutic applications for bone regeneration. PMID- 30275448 TI - Outward open conformation of a Major Facilitator Superfamily multidrug/H+ antiporter provides insights into switching mechanism. AB - Multidrug resistance (MDR) poses a major challenge to medicine. A principle cause of MDR is through active efflux by MDR transporters situated in the bacterial membrane. Here we present the crystal structure of the major facilitator superfamily (MFS) drug/H+ antiporter MdfA from Escherichia coli in an outward open conformation. Comparison with the inward facing (drug binding) state shows that, in addition to the expected change in relative orientations of the N- and C terminal lobes of the antiporter, the conformation of TM5 is kinked and twisted. In vitro reconstitution experiments demonstrate the importance of selected residues for transport and molecular dynamics simulations are used to gain insights into antiporter switching. With the availability of structures of alternative conformational states, we anticipate that MdfA will serve as a model system for understanding drug efflux in MFS MDR antiporters.

PMID- 30275451 TI - Nitrogen Dynamics in Soil Fertilized with Slow Release Brown Coal-Urea Fertilizers. AB - Reducing the release rate of urea can increase its use efficiency and minimize negative effects on the environment. A novel fertilizer material that was formed by blending brown coal (BC) with urea, delayed fertilizer N release in controlled climatic conditions in a glasshouse, through strong retention facilitated by the extensive surface area, porous structure and chemical functional groups in the BC. However, the role of BC as a carrier of synthetic urea and the effect of their interaction with various soil types on the dynamics and mineralization of N remains largely unclear. Therefore, a soil column incubation study was conducted to assess the release, transformation and transportation of N from several different brown coal-urea (BCU) granules, compared to commercial urea. Blending and subsequent granulation of urea with BC substantially increased fertilizer N retention in soil by decreasing gaseous emissions and leaching of N compared to urea alone, irrespective of soil type. The BCU granule containing the highest proportion of BC had lower leaching and gaseous emissions and maintained considerably higher mineral and mineralizable N in topsoil. Possible modes of action of the BCU granules have been proposed, emphasizing the role of BC in enhancing N retention over a longer period of time. The results support the notion that BCU granules can be used as a slow release and enhanced efficiency fertilizer for increasing availability and use efficiency of N by crops. PMID- 30275452 TI - Transcriptome Analysis of Intrusively Growing Flax Fibers Isolated by Laser Microdissection. AB - The intrusive growth, a type of plant cell elongation occurring in the depths of plant tissues, is characterized by the invasion of a growing cell between its neighbours due to a higher rate of elongation. In order to reveal the largely unknown molecular mechanisms of intrusive growth, we isolated primary flax phloem fibers specifically at the stage of intrusive growth by laser microdissection. The comparison of the RNA-Seq data from several flax stem parts enabled the characterization of those processes occurring specifically during the fiber intrusive elongation. The revealed molecular players are summarized as those involved in the supply of assimilates and support of turgor pressure, cell wall enlargement and modification, regulation by transcription factors and hormones, and responses to abiotic stress factors. The data obtained in this study provide a solid basis for developing approaches to manipulate fiber intrusive elongation, which is of importance both for plant biology and the yield of fiber crops. PMID- 30275453 TI - Partial depletion of CD206-positive M2-like macrophages induces proliferation of beige progenitors and enhances browning after cold stimulation. AB - Beige adipocytes are an inducible form of thermogenic adipocytes that become interspersed within white adipose tissue (WAT) depots in response to cold exposure. Previous studies have shown that type 2 cytokines and M2 macrophages induce cold-induced browning in inguinal WAT (ingWAT) by producing catecholamines. Exactly how the conditional and partial depletion of CD206+ M2 like macrophages regulates the cold-induced browning of ingWAT, however, remains unknown. We examined the role of CD206+ M2-like macrophages in the cold-induced browning of WAT using genetically engineered CD206DTR mice, in which CD206+ M2 like macrophages were conditionally depleted. The partial depletion of CD206+ M2 like enhanced UCP1 expression in ingWAT, as shown by immunostaining, and also upregulated the expression of Ucp1 and other browning-related marker genes in ingWAT after cold exposure. A flow cytometry analysis showed that the partial depletion of CD206+ M2-like macrophages caused an increase in the number of beige progenitors in ingWAT in response to cold. Thus, we concluded that CD206+ M2-like macrophages inhibit the proliferation of beige progenitors and that the partial depletion of CD206+ M2-like macrophages releases this inhibition, thereby enhancing browning and insulin sensitivity. PMID- 30275454 TI - Damage-induced reactive oxygen species enable zebrafish tail regeneration by repositioning of Hedgehog expressing cells. AB - Many aquatic vertebrates have a remarkable ability to regenerate limbs and tails after amputation. Previous studies indicate that reactive oxygen species (ROS) signalling initiates regeneration, but the mechanism by which this takes place is poorly understood. Developmental signalling pathways have been shown to have proregenerative roles in many systems. However, whether these are playing roles that are specific to regeneration, or are simply recapitulating their developmental functions is unclear. Here, we analyse zebrafish larval tail regeneration and find evidence that ROS released upon wounding cause repositioning of notochord cells to the damage site. These cells secrete Hedgehog ligands that are required for regeneration. Hedgehog signalling is not required for normal tail development suggesting that it has a regeneration-specific role. Our results provide a model for how ROS initiate tail regeneration, and indicate that developmental signalling pathways can play regenerative functions that are not directly related to their developmental roles. PMID- 30275455 TI - Small-molecule AgrA inhibitors F12 and F19 act as antivirulence agents against Gram-positive pathogens. AB - Small-molecule antivirulence agents represent a promising alternative or adjuvant to antibiotics. These compounds disarm pathogens of disease-causing toxins without killing them, thereby diminishing survival pressure to develop resistance. Here we show that the small-molecule antivirulence agents F12 and F19 block staphylococcal transcription factor AgrA from binding to its promoter. Consequently, toxin expression is inhibited, thus preventing host cell damage by Gram-positive pathogens. Broad spectrum efficacy against Gram-positive pathogens is due to the existence of AgrA homologs in many Gram-positive bacteria. F12 is more efficacious in vitro and F19 works better in vivo. In a murine MRSA bacteremia/sepsis model, F19 treatment alone resulted in 100% survival while untreated animals had 70% mortality. Furthermore, F19 enhances antibiotic efficacy in vivo. Notably, in a murine MRSA wound infection model, combination of F19 with antibiotics resulted in bacterial load reduction. Thus, F19 could be used alone or in combination with antibiotics to prevent and treat infections of Gram-positive pathogens.

PMID- 30275457 TI - Multibandgap quantum dot ensembles for solar-matched infrared energy harvesting. AB - As crystalline silicon solar cells approach in efficiency their theoretical limit, strategies are being developed to achieve efficient infrared energy harvesting to augment silicon using solar photons from beyond its 1100 nm absorption edge. Herein we report a strategy that uses multi-bandgap lead sulfide colloidal quantum dot (CQD) ensembles to maximize short-circuit current and open circuit voltage simultaneously. We engineer the density of states to achieve simultaneously a large quasi-Fermi level splitting and a tailored optical response that matches the infrared solar spectrum. We shape the density of states by selectively introducing larger-bandgap CQDs within a smaller-bandgap CQD population, achieving a 40 meV increase in open-circuit voltage. The near-unity internal quantum efficiency in the optimized multi-bandgap CQD ensemble yielded a maximized photocurrent of 3.7 +/- 0.2 mA cm-2. This provides a record for silicon filtered power conversion efficiency equal to one power point, a 25% (relative) improvement compared to the best previously-reported results.

AB - The menstrual cycle is an essential life rhythm governed by interacting levels of progesterone, estradiol, follicular stimulating, and luteinizing hormones. To study metabolic changes, biofluids were collected at four timepoints in the menstrual cycle from 34 healthy, premenopausal women. Serum hormones, urinary luteinizing hormone and self-reported menstrual cycle timing were used for a 5 phase cycle classification. Plasma and urine were analyzed using LC-MS and GC-MS for metabolomics and lipidomics; serum for clinical chemistries; and plasma for B vitamins using HPLC-FLD. Of 397 metabolites and micronutrients tested, 208 were significantly (p < 0.05) changed and 71 reached the FDR 0.20 threshold showing rhythmicity in neurotransmitter precursors, glutathione metabolism, the urea cycle, 4-pyridoxic acid, and 25-OH vitamin D. In total, 39 amino acids and derivatives and 18 lipid species decreased (FDR < 0.20) in the luteal phase, possibly indicative of an anabolic state during the progesterone peak and recovery during menstruation and the follicular phase. The reduced metabolite levels observed may represent a time of vulnerability to hormone related health issues such as PMS and PMDD, in the setting of a healthy, rhythmic state. These results provide a foundation for further research on cyclic differences in nutrient-related metabolites and may form the basis of novel nutrition strategies for women. PMID- 30275462 TI - Metabolic adaptations to high-fat diet. PMID- 30275460 TI - The role of hypoxia-inducible factors in metabolic diseases. AB - Hypoxia-inducible factors (HIFs), a family of transcription factors activated by hypoxia, consist of three alpha-subunits (HIF1alpha, HIF2alpha and HIF3alpha) and one beta-subunit (HIF1beta), which serves as a heterodimerization partner of the HIFalpha subunits. HIFalpha subunits are stabilized from constitutive degradation by hypoxia largely through lowering the activity of the oxygen-dependent prolyl hydroxylases that hydroxylate HIFalpha, leading to their proteolysis. HIF1alpha and HIF2alpha are expressed in different tissues and regulate target genes involved in angiogenesis, cell proliferation and inflammation, and their expression is associated with different disease states. HIFs have been widely studied because of their involvement in cancer, and HIF2alpha-specific inhibitors are being investigated in clinical trials for the treatment of kidney cancer. Although cancer has been the major focus of research on HIF, evidence has emerged that this pathway has a major role in the control of metabolism and influences metabolic diseases such as obesity, type 2 diabetes mellitus and non-alcoholic fatty liver disease. Notably increased HIF1alpha and HIF2alpha signalling in adipose tissue and small intestine, respectively, promotes metabolic diseases in diet-induced disease models. Inhibition of HIF1alpha and HIF2alpha decreases the adverse diet-induced metabolic phenotypes, suggesting that they could be drug targets for the treatment of metabolic diseases. PMID- 30275459 TI - FIBP knockdown attenuates growth and enhances chemotherapy in colorectal cancer via regulating GSK3beta-related pathways. AB - Colorectal cancer stem cells (CSCs), characterized by self-renewal ability and high expression of proliferative genes, contribute to the chemoresistance of colorectal cancer (CRC). We aimed to identify the molecular mechanisms underlying CRC chemoresistance through comprehensive bioinformatics screenings and experimental confirmation of gene functions. We found that high expression of FGF1 intracellular binding protein (FIBP) was correlated with chemoresistance and poor prognosis in CRC patients. Therefore, the chemoresistant CRC cell line HCT116-CSC with high expression of the stem cell markers CD44 and CD133 was established for further phenotypic tests. FIBP knockdown inhibited proliferation, enhanced chemotherapy effects, and attenuated the stemness markers of CRC cells in vivo and in vitro. Through RNA-seq and gene set enrichment analysis, we identified cyclin D1 as a key downstream target in FIBP-regulated cell cycle progression and proliferation. Moreover, FIBP bound to GSK3beta, inhibited its phosphorylation at Tyr216, and activated beta-catenin/TCF/cyclin D1 signaling in HCT116-CSCs. Additional GSK3beta knockdown reversed the FIBP silencing-induced inhibition of proliferation and decreased stemness marker expression in HCT116 CSCs. Furthermore, DNA methylation profiling suggested that FIBP regulated the stemness of CRC cells via methylation activity that was dependent on GSK3beta but independent of beta-catenin signaling. Our data illuminate the potential of FIBP as a novel therapeutic target for treating chemoresistant CRC through inhibition of GSK3beta-related signaling.

PMID- 30275465 TI - Rapid sex-specific evolution of age at maturity is shaped by genetic architecture in Atlantic salmon. AB - Understanding the mechanisms by which populations adapt to their environments is a fundamental aim in biology. However, it remains challenging to identify the genetic basis of traits, provide evidence of genetic changes and quantify phenotypic responses. Age at maturity in Atlantic salmon represents an ideal trait to study contemporary adaptive evolution as it has been associated with a single locus in the vgll3 region and has also strongly changed in recent decades. Here, we provide an empirical example of contemporary adaptive evolution of a large-effect locus driving contrasting sex-specific evolutionary responses at the phenotypic level. We identified an 18% decrease in the vgll3 allele associated with late maturity in a large and diverse salmon population over 36 years, induced by sex-specific selection during sea migration. Those genetic changes resulted in a significant evolutionary response only in males, due to sex specific dominance patterns and vgll3 allelic effects. The vgll3 allelic and dominance effects differed greatly in a second population and were likely to generate different selection and evolutionary patterns. Our study highlights the importance of knowledge of genetic architecture to better understand fitness trait evolution and phenotypic diversity. It also emphasizes the potential role of adaptive evolution in the trend towards earlier maturation observed in numerous Atlantic salmon populations worldwide. PMID- 30275466 TI - Personality shapes pair bonding in a wild bird social system. AB - Mated pair bonds are integral to many animal societies, yet how individual variation in behaviour influences their formation remains largely unknown. In a population of wild great tits (Parus major), we show that personality shapes pair bonding: proactive males formed stronger pre-breeding pair bonds by meeting their future partners sooner and increasing their relationship strength at a faster rate. As a result, proactive males sampled fewer potential mates. Thus, personality may have important implications for social relationship dynamics and emergent social structure. PMID- 30275467 TI - Mechanotransduction is required for establishing and maintaining mature inner hair cells and regulating efferent innervation. AB - In the adult auditory organ, mechanoelectrical transducer (MET) channels are essential for transducing acoustic stimuli into electrical signals. In the absence of incoming sound, a fraction of the MET channels on top of the sensory hair cells are open, resulting in a sustained depolarizing current. By genetically manipulating the in vivo expression of molecular components of the MET apparatus, we show that during pre-hearing stages the MET current is essential for establishing the electrophysiological properties of mature inner hair cells (IHCs). If the MET current is abolished in adult IHCs, they revert into cells showing electrical and morphological features characteristic of pre hearing IHCs, including the re-establishment of cholinergic efferent innervation. The MET current is thus critical for the maintenance of the functional properties of adult IHCs, implying a degree of plasticity in the mature auditory system in response to the absence of normal transduction of acoustic signals. PMID- 30275469 TI - Lysosomal storage diseases. AB - Lysosomal storage diseases (LSDs) are a group of over 70 diseases that are characterized by lysosomal dysfunction, most of which are inherited as autosomal recessive traits. These disorders are individually rare but collectively affect 1 in 5,000 live births. LSDs typically present in infancy and childhood, although adult-onset forms also occur. Most LSDs have a progressive neurodegenerative clinical course, although symptoms in other organ systems are frequent. LSD associated genes encode different lysosomal proteins, including lysosomal enzymes and lysosomal membrane proteins. The lysosome is the key cellular hub for macromolecule catabolism, recycling and signalling, and defects that impair any of these functions cause the accumulation of undigested or partially digested macromolecules in lysosomes (that is, 'storage') or impair the transport of molecules, which can result in cellular damage. Consequently, the cellular pathogenesis of these diseases is complex and is currently incompletely understood. Several LSDs can be treated with approved, disease-specific therapies that are mostly based on enzyme replacement. However, small-molecule therapies, including substrate reduction and chaperone therapies, have also been developed and are approved for some LSDs, whereas gene therapy and genome editing are at advanced preclinical stages and, for a few disorders, have already progressed to the clinic. PMID- 30275470 TI - Interface dominated cooperative nanoprecipitation in interstitial alloys. AB - Steels belong to one of the best established materials, however, the mechanisms of various phase transformations down to the nano length scale are still not fully clear. In this work, high-resolution transmission electron microscopy is combined with atomistic simulations to study the nanoscale carbide precipitation in a Fe-Cr-C alloy. We identify a cooperative growth mechanism that connects host lattice reconstruction and interstitial segregation at the growing interface front, which leads to a preferential growth of cementite (Fe3C) nanoprecipitates along a particular direction. This insight significantly improves our understanding of the mechanisms of nanoscale precipitation in interstitial alloys, and paves the way for engineering nanostructures to enhance the mechanical performance of alloys. PMID- 30275468 TI - Cell-specific proteome analyses of human bone marrow reveal molecular features of age-dependent functional decline. AB - Diminishing potential to replace damaged tissues is a hallmark for ageing of somatic stem cells, but the mechanisms remain elusive. Here, we present proteome wide atlases of age-associated alterations in human haematopoietic stem and progenitor cells (HPCs) and five other cell populations that constitute the bone marrow niche. For each, the abundance of a large fraction of the ~12,000 proteins identified is assessed in 59 human subjects from different ages. As the HPCs become older, pathways in central carbon metabolism exhibit features reminiscent of the Warburg effect, where glycolytic intermediates are rerouted towards anabolism. Simultaneously, altered abundance of early regulators of HPC differentiation reveals a reduced functionality and a bias towards myeloid differentiation. Ageing causes alterations in the bone marrow niche too, and diminishes the functionality of the pathways involved in HPC homing. The data represent a valuable resource for further analyses, and for validation of knowledge gained from animal models. PMID- 30275472 TI - Reviewer recognition.

PMID- 30275471 TI - Chromosome 4q25 Variant rs6817105 Bring Sinus Node Dysfunction and Left Atrial Enlargement. AB - Genome-wide association studies have reported a strong association of the single nucleotide polymorphism (SNP) rs6817105 (T > C) on chromosome 4q25 with atrial fibrillation (AF), but phenotype alterations conferred by this SNP have not been described. We genotyped SNP rs6817105 and examined the relationships among rs6817105 genotype, clinical characteristics, echocardiographic parameters, and electrophysiological parameters in 574 AF patients and 1,554 non-AF controls. Further, multiple microRNAs (miRNAs) are reported to be involved in atrial remodeling and AF pathogenesis, so we investigated relationships between rs6817105 genotype and serum concentrations of 2555 miRNAs. The rs6817105 minor allele frequency was significantly higher in AF patients than non-AF controls (66% vs. 47%, odds ratio 2.12, p = 4.9 * 10-26). Corrected sinus node recovery time (CSRT) was longer and left atrial volume index (LAVI) was larger in AF patients with the rs6817105 minor allele than patient non-carriers (CSRT: CC 557 +/- 315 ms, CT 486 +/- 273 ms, TT 447 +/- 234 ms, p = 0.001; LAVI: CC 43.6 +/- 12.1, CT 42.4 +/- 13.6, TT 39.8 +/- 11.6, p = 0.030). There were no significant differences between rs6817105 genotype and the serum concentrations of miRNAs. These findings strongly implicate rs6817105 minor allele in sinus node dysfunction and left atrial enlargement. PMID- 30275473 TI - Pastoralism may have delayed the end of the green Sahara. AB - The climate deterioration after the most recent African humid period (AHP) is a notable past example of desertification. Evidence points to a human population expansion in northern Africa prior to this, associated with the introduction of pastoralism. Here we consider the role, if any, of this population on the subsequent ecological collapse. Using a climate-vegetation model, we estimate the natural length of the most recent AHP. The model indicates that the system was most susceptible to collapse between 7 and 6 ka; at least 500 years before the observed collapse. This suggests that the inclusion of increasing elements of pastoralism was an effective adaptation to the regional environmental changes. Pastoralism also appears to have slowed the deterioration caused by orbitally driven climate change. This supports the view that modern pastoralism is not only sustainable, but beneficial for the management of the world's dryland environments. PMID- 30275475 TI - Lysosomal storage disorders. PMID- 30275474 TI - Ebola viral dynamics in nonhuman primates provides insights into virus immuno pathogenesis and antiviral strategies. AB - Despite several clinical trials implemented, no antiviral drug could demonstrate efficacy against Ebola virus. In non-human primates, early initiation of polymerase inhibitors favipiravir and remdesivir improves survival, but whether they could be effective in patients is unknown. Here we analyze the impact of antiviral therapy by using a mathematical model that integrates virological and immunological data of 44 cynomolgus macaques, left untreated or treated with favipiravir. We estimate that favipiravir has a ~50% efficacy in blocking viral production, which results in reducing virus growth and cytokine storm while IFNalpha reduces cell susceptibility to infection. Simulating the effect of delayed initiations of treatment, our model predicts survival rates of 60% for favipiravir and 100% for remdesivir when treatment is initiated within 3 and 4 days post infection, respectively. These results improve the understanding of Ebola immuno-pathogenesis and can help optimize antiviral evaluation in future outbreaks.

PMID- 30275476 TI - Nearly all the sky is covered by Lyman-alpha emission around high-redshift galaxies. AB - Galaxies are surrounded by large reservoirs of gas, mostly hydrogen, that are fed by inflows from the intergalactic medium and by outflows from galactic winds. Absorption-line measurements along the lines of sight to bright and rare background quasars indicate that this circumgalactic medium extends far beyond the starlight seen in galaxies, but very little is known about its spatial distribution. The Lyman-alpha transition of atomic hydrogen at a wavelength of 121.6 nanometres is an important tracer of warm (about 104 kelvin) gas in and around galaxies, especially at cosmological redshifts greater than about 1.6 at which the spectral line becomes observable from the ground. Tracing cosmic hydrogen through its Lyman-alpha emission has been a long-standing goal of observational astrophysics1-3, but the extremely low surface brightness of the spatially extended emission is a formidable obstacle. A new window into circumgalactic environments was recently opened by the discovery of ubiquitous extended Lyman-alpha emission from hydrogen around high-redshift galaxies4,5. Such measurements were previously limited to especially favourable systems6-8 or to the use of massive statistical averaging9,10 because of the faintness of this emission. Here we report observations of low-surface-brightness Lyman-alpha emission surrounding faint galaxies at redshifts between 3 and 6. We find that the projected sky coverage approaches 100 per cent. The corresponding rate of incidence (the mean number of Lyman-alpha emitters penetrated by any arbitrary line of sight) is well above unity and similar to the incidence rate of high column-density absorbers frequently detected in the spectra of distant quasars11 14. This similarity suggests that most circumgalactic atomic hydrogen at these redshifts has now been detected in emission.

AB - Expanded carrier screening (ECS) has been demonstrated to increase the detection rate of carriers compared with traditional tests. The aim of this study was to assess the potential value of ECS for clinical application in Southern China, a region with high prevalence of thalassemia and with diverse ethnic groups, and to provide a reference for future implementations in areas with similar population characteristics. A total of 10,476 prenatal/preconception couples from 34 self reported ethnic groups were simultaneously tested and analyzed anonymously for 11 Mendelian disorders using targeted next-generation sequencing. Overall, 27.49% of individuals without self-reported family history of disorders were found to be carriers of at least 1 of the 11 conditions, and the carrier frequency varied greatly between ethnic groups, ranging from 4.15% to 81.35%. Furthermore, 255 couples (2.43%) were identified as carrier couples at an elevated risk having an affected baby, sixty-five of which would not have been identified through the existing screening strategy, which only detects thalassemia. The modeled risk of fetuses being affected by any of the selected disorders was 531 per 100,000 (95% CI, 497-567 per 100,000). Our data demonstrate the feasibility of ECS, and provide evidence that ECS is a promising alternative to traditional one-condition screening strategies. The lessons learned from this experience should be applicable for other countries or regions with diverse ethnic groups.

AB - With advancing technology and the consequent shift towards an increasing application of molecular genetic techniques (e.g., microarrays, next-generation sequencing) with the potential for higher resolution in specific contexts, as well as the application of combined testing strategies for the diagnosis of chromosomal disorders, it is crucial that cytogenetic/cytogenomic services keep up to date with technology and have documents that provide guidance in this constantly evolving scenario. These new guidelines therefore aim to provide an updated, practical and easily available document that will enable genetic laboratories to operate within acceptable standards and to maintain a quality service. PMID- 30275487 TI - Distribution and phylogenetics of whiteflies and their endosymbiont relationships after the Mediterranean species invasion in Brazil. AB - The Bemisia tabaci is a polyphagous insect and a successful vector of plant viruses. B. tabaci is a species complex and in Brazil native species from the New World (NW) group, as well as the invasive species, Middle East-Asia Minor 1 (MEAM1) and Mediterranean (MED) were reported. For better understanding the distribution of the different species four years after the Mediterranean species invasion in Brazil, whiteflies were collected from 237 locations throughout the country between the years of 2013 and 2017, species were identified and the facultative endosymbionts detected. The survey revealed that MEAM1 was the prevalent species found on major crops across Brazil. It is the only species present in North, Northwestern and Central Brazil and was associated with virus infected plants. MED was found in five States from Southeast to South regions, infesting mainly ornamental plants and was not associated with virus-infected plants. The prevalent endosymbionts identified in MEAM1 were Hamiltonella and Rickettsia; and the mtCOI analysis revealed low genetic diversity for MEAM1. In contrast, several different endosymbionts were identified in MED including Hamiltonella, Rickettsia, Wolbachia and Arsenophonus; and two distinct genetic groups were found based on the mtCOI analysis. Monitoring the distribution of the whiteflies species in Brazil is essential for proper management of this pest. PMID- 30275488 TI - Experimental evidence for the enhanced and reduced stopping regimes for protons propagating through hot plasmas. AB - Our understanding of the dynamics of ion collisional energy loss in a plasma is still not complete, in part due to the difficulty and lack of high-quality experimental measurements. These measurements are crucial to benchmark existing models. Here, we show that such a measurement is possible using high-flux proton beams accelerated by high intensity short pulse lasers, where there is a high number of particles in a picosecond pulse, which is ideal for measurements in quickly expanding plasmas. By reducing the energy bandwidth of the protons using a passive selector, we have made proton stopping measurements in partially ionized Argon and fully ionized Hydrogen plasmas with electron temperatures of hundreds of eV and densities in the range 1020-1021 cm-3. In the first case, we have observed, consistently with previous reports, enhanced stopping of protons when compared to stopping power in non-ionized gas. In the second case, we have observed for the first time the regime of reduced stopping, which is theoretically predicted in such hot and fully ionized plasma. The versatility of these tunable short-pulse laser based ion sources, where the ion type and energy can be changed at will, could open up the possibility for a variety of ion stopping power measurements in plasmas so long as they are well characterized in terms of temperature and density. In turn, these measurements will allow tests of the validity of existing theoretical models.

AB - Chronic kidney disease is a worldwide problem, and Pb contamination is a potential risk factor. Since current biomarkers are not sensitive for the diagnosis of Pb-induced nephrotoxicity, novel biomarkers are needed. Metformin has both hypoglycaemic effects and reno-protection ability. However, its mechanism of action is unknown. We aimed to discover the early biomarkers for the diagnosis of low-level Pb-induced nephrotoxicity and understand the mechanism of reno-protection of metformin. Male Wistar rats were randomly divided into control, Pb, Pb + ML, Pb + MH and MH groups. Pb (250 ppm) was given daily via drinking water. Metformin (50 or 100 mg/kg/d) was orally administered. Urine was analysed by nuclear magnetic resonance (NMR)-based metabolomics coupled with multivariate statistical analysis, and potential biomarkers were subsequently quantified. The results showed that Pb-induced nephrotoxicity was closely correlated with the elevation of 5-aminolevulinic acid, D-lactate and guanidinoacetic acid in urine. After co-treatment with metformin, 5 aminolevulinic acid and D-lactate were decreased. This is the first demonstration that urinary 5-aminolevulinic acid, D-lactate and guanidinoacetic acid could be early biomarkers of low-level Pb-induced nephrotoxicity in rats. The reno protection of metformin might be attributable to the reduction of D-lactate excretion.

PMID- 30275492 TI - Extensive Vibrational Characterisation and Long-Term Monitoring of Honeybee Dorso Ventral Abdominal Vibration signals. AB - A very common honeybee signal is the dorso-ventral abdominal vibration (DVAV) signal, widely accepted as a modulatory signal meaning: "prepare for greater activity". In this study, using ultra-sensitive accelerometer technology embedded in the honeycomb, we visually confirm the one-to-one relationship between a DVAV signal being produced and the resulting accelerometer waveform, allowing the measurement of DVAV signals without relying on any visual inspection. We then demonstrate a novel method for the continuous in-situ non-invasive automated monitoring of this honeybee signal, not previously known to induce any vibration into the honeycomb, and most often inaudible to human hearing. We monitored a total of three hives in the UK and France, showing that the signal is very common, highly repeatable and occurs more frequently at night, exhibiting a distinct decrease in instances and increase in amplitude towards mid-afternoon. We also show an unprecedented increase in the cumulative amplitude of DVAV signals occurring in the hours preceding and following a primary swarm. We conclude that DVAV signals may have additional functions beyond solely being a foraging activation signal, and that the amplitude of the signal might be indicative of the switching of its purpose.

AB - Magnetic skyrmions are knot-like quasiparticles. They are candidates for non volatile data storage in which information is moved between fixed read and write terminals. The read-out operation of skyrmion-based spintronic devices will rely on the electrical detection of a single magnetic skyrmion within a nanostructure. Here we present Pt/Co/Ir nanodiscs that support skyrmions at room temperature. We measured the Hall resistivity and simultaneously imaged the spin texture using magnetic scanning transmission X-ray microscopy. The Hall resistivity is correlated to both the presence and size of the skyrmion. The size-dependent part matches the expected anomalous Hall signal when averaging the magnetization over the entire disc. We observed a resistivity contribution that only depends on the number and sign of skyrmion-like objects present in the disc. Each skyrmion gives rise to 22 +/- 2 nOmega cm irrespective of its size. This contribution needs to be considered in all-electrical detection schemes applied to skyrmion-based devices. Not only the area of Neel skyrmions but also their number and sign contribute to their Hall resistivity. PMID- 30275495 TI - Bacteria photosensitized by intracellular gold nanoclusters for solar fuel production. AB - The demand for renewable and sustainable fuel has prompted the rapid development of advanced nanotechnologies to effectively harness solar power. The construction of photosynthetic biohybrid systems (PBSs) aims to link preassembled biosynthetic pathways with inorganic light absorbers. This strategy inherits both the high light-harvesting efficiency of solid-state semiconductors and the superior catalytic performance of whole-cell microorganisms. Here, we introduce an intracellular, biocompatible light absorber, in the form of gold nanoclusters (AuNCs), to circumvent the sluggish kinetics of electron transfer for existing PBSs. Translocation of these AuNCs into non-photosynthetic bacteria enables photosynthesis of acetic acid from CO2. The AuNCs also serve as inhibitors of reactive oxygen species (ROS) to maintain high bacterium viability. With the dual advantages of light absorption and biocompatibility, this new generation of PBS can efficiently harvest sunlight and transfer photogenerated electrons to cellular metabolism, realizing CO2 fixation continuously over several days. PMID- 30275490 TI - Genome-wide discovery of somatic regulatory variants in diffuse large B-cell lymphoma. AB - Diffuse large B-cell lymphoma (DLBCL) is an aggressive cancer originating from mature B-cells. Prognosis is strongly associated with molecular subgroup, although the driver mutations that distinguish the two main subgroups remain poorly defined. Through an integrative analysis of whole genomes, exomes, and transcriptomes, we have uncovered genes and non-coding loci that are commonly mutated in DLBCL. Our analysis has identified novel cis-regulatory sites, and implicates recurrent mutations in the 3' UTR of NFKBIZ as a novel mechanism of oncogene deregulation and NF-kappaB pathway activation in the activated B-cell (ABC) subgroup. Small amplifications associated with over-expression of FCGR2B (the Fcgamma receptor protein IIB), primarily in the germinal centre B-cell (GCB) subgroup, correlate with poor patient outcomes suggestive of a novel oncogene. These results expand the list of subgroup driver mutations that may facilitate implementation of improved diagnostic assays and could offer new avenues for the development of targeted therapeutics. PMID- 30275496 TI - The prevalence of olfactory- versus visual-signal encounter by searching bumblebees. AB - While the phrase 'foraging bumblebee' brings to mind a bumbling bee flying flower to flower in a sunny meadow, foraging is a complicated series of behaviors such as: locating a floral patch; selecting a flower-type; learning handling skills for pollen and nectar extraction; determining when to move-on from a patch; learning within-patch paths (traplining); and learning efficient hive-to-patch routes (spatial navigation). Thus the term 'forager' encompasses multiple distinct behaviors that rely on different sensory modalities. Despite a robust literature on bumblebee foraging behavior, few studies are directly relevant to sensory-guided search; i.e. how workers locate novel patches. The first step in answering this question is to determine what sensory information is available to searching bumblebees. This manuscript presents a computational model that elucidates the relative frequency of visual and olfactory cues that are available to workers searching for floral resources under a range of ecologically relevant scenarios. Model results indicate that odor is the most common sensory cue encountered during search flights. When the likelihood of odor-plume contact is higher, odor-encounter is ubiquitous. While integrative (visual + olfactory) cues are common when foragers are searching for larger flowers (e.g. Echinacea), they become rare when foragers are searching for small flowers (e.g. Penstemon). Visual cues are only encountered in isolation when foragers are seeking large flowers with a low odor-plume contact probability. These results indicate that despite the multisensory nature of floral signals, different modalities may be encountered in isolation during search-behavior, as opposed to the reliably multimodal signals encountered during patch-exploitation or nectar/ pollen acquisition. PMID- 30275498 TI - Digital coding of mechanical stress in a dynamic covalent shape memory polymer network. AB - Controlling stresses in materials presents many unusual opportunities for their engineering applications. The potential for current approaches is severely limited by the intrinsic tie between the stress and the geometric shape. Here, we report a material concept that allows stress management in a highly efficient digital manner while decoupling the stress and the geometric shape. This is realized in a dynamic covalent shape memory polymer network, for which the elastic shape memory sets the baseline stress level and maintains the geometric shape while the plasticity enabled by the dynamic bond exchange allows stress tuning. With a digital gray scale photothermal mechanism, any arbitrarily defined stress distribution can be created in a free-standing polymer film. The naturally invisible stresses can be further visualized as mechanical colors under polarized light, revealing its potential for encoding hidden information. Our approach expands the technological potential in many areas for which stresses are relevant. PMID- 30275497 TI - Regulatory control of DNA end resection by Sae2 phosphorylation. AB - DNA end resection plays a critical function in DNA double-strand break repair pathway choice. Resected DNA ends are refractory to end-joining mechanisms and are instead channeled to homology-directed repair. Using biochemical, genetic, and imaging methods, we show that phosphorylation of Saccharomyces cerevisiae Sae2 controls its capacity to promote the Mre11-Rad50-Xrs2 (MRX) nuclease to initiate resection of blocked DNA ends by at least two distinct mechanisms. First, DNA damage and cell cycle-dependent phosphorylation leads to Sae2 tetramerization. Second, and independently, phosphorylation of the conserved C terminal domain of Sae2 is a prerequisite for its physical interaction with Rad50, which is also crucial to promote the MRX endonuclease. The lack of this interaction explains the phenotype of rad50S mutants defective in the processing of Spo11-bound DNA ends during meiotic recombination. Our results define how phosphorylation controls the initiation of DNA end resection and therefore the choice between the key DNA double-strand break repair mechanisms. PMID- 30275499 TI - Cognitive dysfunction in atrial fibrillation. AB - Atrial fibrillation (AF) is the most common arrhythmia in adults, and its incidence and prevalence increase with age. The risk of cognitive impairment and dementia also increases with age, and both AF and cognitive impairment or dementia share important risk factors. In meta-analyses of published studies, AF is associated with a 2.4-fold and 1.4-fold increase in the risk of dementia in patients with or without a history of stroke, respectively. This association is independent of shared risk factors such as hypertension and diabetes mellitus. Neuroimaging has illustrated several potential mechanisms of cognitive decline in patients with AF. AF is associated with increased prevalence of silent cerebral infarcts, and more recent data also suggest an increased prevalence of cerebral microbleeds with AF. AF is also associated with a pro-inflammatory state, and the relationship between AF-induced systemic inflammation and dementia remains to be investigated. Preliminary reports indicate that anticoagulation medication including warfarin can reduce the risk of cognitive impairment in patients with AF. Catheter ablation, increasingly used to maintain sinus rhythm in patients with AF, is associated with the formation of new silent cerebral lesions. The majority of these lesions are not detectable after 1 year, and insufficient data are available to evaluate their effect on cognition. Large prospective studies are urgently needed to confirm the association between AF and dementia, to elucidate the associated mechanisms, and to investigate the effect of anticoagulation and rhythm control on cognition. PMID- 30275501 TI - Tunable phonon blockade in weakly nonlinear coupled mechanical resonators via Coulomb interaction. AB - Realizing quantum mechanical behavior in micro- and nanomechanical resonators has attracted continuous research effort. One of the ways for observing quantum nature of mechanical objects is via the mechanism of phonon blockade. Here, we show that phonon blockade could be achieved in a system of two weakly nonlinear mechanical resonators coupled by a Coulomb interaction. The optimal blockade arises as a result of the destructive quantum interference between paths leading to two-phonon excitation. It is observed that, in comparison to a single drive applied on one mechanical resonator, driving both the resonators can be beneficial in many aspects; such as, in terms of the temperature sensitivity of phonon blockade and also with regard to the tunability, by controlling the amplitude and the phase of the second drive externally. We also show that via a radiation pressure induced coupling in an optomechanical cavity, phonon correlations can be measured indirectly in terms of photon correlations of the cavity mode. PMID- 30275500 TI - Elucidating a role for the cytoplasmic domain in the Mycobacterium tuberculosis mechanosensitive channel of large conductance. AB - Microbial survival in dynamic environments requires the ability to successfully respond to abrupt changes in osmolarity. The mechanosensitive channel of large conductance (MscL) is a ubiquitous channel that facilitates the survival of bacteria and archaea under severe osmotic downshock conditions by relieving excess turgor pressure in response to increased membrane tension. A prominent structural feature of MscL, the cytoplasmic C-terminal domain, has been suggested to influence channel assembly and function. In this report, we describe the X-ray crystal structure and electrophysiological properties of a C-terminal domain truncation of the Mycobacterium tuberculosis MscL (MtMscLDeltaC). A crystal structure of MtMscLDeltaC solubilized in the detergent n-dodecyl-beta-D maltopyranoside reveals the pentameric, closed state-like architecture for the membrane spanning region observed in the previously solved full-length MtMscL. Electrophysiological characterization demonstrates that MtMscLDeltaC retains mechanosensitivity, but with conductance and tension sensitivity more closely resembling full length EcMscL than MtMscL. This study establishes that the C terminal domain of MtMscL is not required for oligomerization of the full-length channel, but rather influences the tension sensitivity and conductance properties of the channel. The collective picture that emerges from these data is that each MscL channel structure has characteristic features, highlighting the importance of studying multiple homologs. PMID- 30275502 TI - A quantitative study on growth variability and production of ochratoxin A and its derivatives by A. carbonarius and A. niger in grape-based medium. AB - Aspergillus carbonarius and Aspergillus niger are the main responsible fungi for the accumulation of ochratoxin A (OTA) in wine grapes. Some strains are able to convert the parent mycotoxin into other compounds by means of hydrolysis and/or conjugation reactions through their defense mechanisms and enzymatic activity, leading to the formation of a modified mycotoxin. Thus, the variability of growth and metabolite production are inherent to the strain, occurring distinctively even when submitted to similar conditions. In this sense, this contribution aimed at determining the variability in multiplication and production of OTA by strains of A. carbonarius and A. niger isolated from grapes, as well as investigating the formation of modified mycotoxins. Strains were incubated in grape-based medium, and the diameter of the colonies measured daily. The determination of OTA was performed by high-performance liquid chromatography and the identification of modified mycotoxins was carried out using high-resolution mass spectrometry. Variabilities in terms of growth and OTA production were assessed across five different strains. Peak production of OTA was detected on day 15, and a decline on day 21 was observed, indicating that the observed reduction may be associated with the degradation or modification of the OTA over time by the fungus. Ethylamide ochratoxin A, a modified mycotoxin identified in this study, provides evidence that there may be underreporting of total mycotoxin levels in food, increasing uncertainty concerning health risks to the population. PMID- 30275503 TI - Hypertrophic cardiomyopathy disease results from disparate impairments of cardiac myosin function and auto-inhibition. AB - Hypertrophic cardiomyopathies (HCM) result from distinct single-point mutations in sarcomeric proteins that lead to muscle hypercontractility. While different models account for a pathological increase in the power output, clear understanding of the molecular basis of dysfunction in HCM is the mandatory next step to improve current treatments. Here, we present an optimized quasi-atomic model of the sequestered state of cardiac myosin coupled to X-ray crystallography and in silico analysis of the mechanical compliance of the lever arm, allowing the systematic study of a large set of HCM mutations and the definition of different mutation classes based on their effects on lever arm compliance, sequestered state stability, and motor functions. The present work reconciles previous models and explains how distinct HCM mutations can have disparate effects on the motor mechano-chemical parameters and yet lead to the same disease. The framework presented here can guide future investigations aiming at finding HCM treatments. PMID- 30275504 TI - Relationship between mean platelet volume and metabolic syndrome in Chinese patients. AB - Mean platelet volume (MPV) is a determinant of activation and variability of platelets (PLT). The focus of this study was to to investigate MPV values in patients with and without metabolic syndrome (MS). It also evaluates the association between them. There are close connections among MPV, MS, and cardiometabolic risk. We compiled age, body mass index, blood cell counts, MPV, and other data of 59976 self-reported healthy volunteers (28428 male, 31548 female), 24.65% of who have MS. The mean age of the group was 48.21 years old. The data was grouped by sex and values of data between men and women groups were analyzed by independent sample's t-test. The relationship between sex and MS was evaluated by chi-square tests. Crude odd ratios of MS between MPV quartiles and 95% confidence intervals were analyzed by binary logistic regression in this study. We found women had higher levels of MPV (10.09 vs. 9.98, P < 0.01) and PLT (228.68 vs. 212.11, P < 0.01) than men. In females, the prevalence of MS was higher in low MPV group than in high MPV groups. The odds of having MS were significantly lower in higher MPV quartiles compared with MPV Quartile 1 in women (Adjusted OR < 1, P < 0.01). This study indicated that MS was inversely associated with MPV in females only. PMID- 30275506 TI - Superoxide dismutase activity enabled by a redox-active ligand rather than metal. AB - Reactive oxygen species are integral to many physiological processes. Although their roles are still being elucidated, they seem to be linked to a variety of disorders and may represent promising drug targets. Mimics of superoxide dismutases, which catalyse the decomposition of O2*- to H2O2 and O2, have traditionally used redox-active metals, which are toxic outside of a tightly coordinating ligand. Purely organic antioxidants have also been investigated but generally require stoichiometric, rather than catalytic, doses. Here, we show that a complex of the redox-inactive metal zinc(II) with a hexadentate ligand containing a redox-active quinol can catalytically degrade superoxide, as demonstrated by both reactivity assays and stopped-flow kinetics studies of direct reactions with O2*- and the zinc(II) complex. The observed superoxide dismutase catalysis has an important advantage over previously reported work in that it is hastened, rather than impeded, by the presence of phosphate, the concentration of which is high under physiological conditions. PMID- 30275507 TI - Sulfone-containing covalent organic frameworks for photocatalytic hydrogen evolution from water. AB - Nature uses organic molecules for light harvesting and photosynthesis, but most man-made water splitting catalysts are inorganic semiconductors. Organic photocatalysts, while attractive because of their synthetic tunability, tend to have low quantum efficiencies for water splitting. Here we present a crystalline covalent organic framework (COF) based on a benzo-bis(benzothiophene sulfone) moiety that shows a much higher activity for photochemical hydrogen evolution than its amorphous or semicrystalline counterparts. The COF is stable under long term visible irradiation and shows steady photochemical hydrogen evolution with a sacrificial electron donor for at least 50 hours. We attribute the high quantum efficiency of fused-sulfone-COF to its crystallinity, its strong visible light absorption, and its wettable, hydrophilic 3.2 nm mesopores. These pores allow the framework to be dye-sensitized, leading to a further 61% enhancement in the hydrogen evolution rate up to 16.3 mmol g-1 h-1. The COF also retained its photocatalytic activity when cast as a thin film onto a support. PMID- 30275505 TI - High Expression of EpCAM and Sox2 is a Positive Prognosticator of Clinical Outcome for Head and Neck Carcinoma. AB - Locally advanced head and neck squamous cell carcinomas (HNSCC) have limited prognosis due to frequent treatment failure. Currently, TNM-classification and human papillomavirus (HPV) infection are the sole clinical prognosticators of outcome. Tumor heterogeneity and stemness based on epithelial-mesenchymal transition reportedly associate with therapy resistance. The capacity of epithelial marker EpCAM (EpEX), stemness regulator Sox2 and mesenchymal marker vimentin to predict clinical outcome of HSNCC patients was assessed upon immunohistochemistry staining in two cohorts of HNSCC patients treated with surgery and adjuvant radio (chemo) therapy (n = 94) and primary radio (chemo) therapy (n = 94), respectively. Prognostic values with respect to overall, disease-free and disease-specific survival were assessed in uni- and multivariate cox proportional hazard models to generate integrated risk scores. EpEX, Sox2 and vimentin displayed substantial inter- and intratumoral heterogeneity. EpEXhigh and Sox2high predicted improved clinical outcome in the discovery cohort and in the HPV-negative sub-cohort. EpEXhigh and Sox2high were confirmed as prognosticators of clinical outcome in the validation cohort treated with definitive radio(chemo)therapy. Importantly, EpEXhigh identified patients with improved survival within the HPV-negative subgroup of the validation cohort. Hence, Sox2high and particularly EpEXhigh have potential as tools to predict clinical performance of HNSCC patients, foremost HPV-negative cases, in the frame of molecular-guided treatment decision-making. PMID- 30275508 TI - Genetic structure and polymorphisms of Gelao ethnicity residing in southwest china revealed by X-chromosomal genetic markers. AB - X-chromosome short tandem repeat markers (X-STRs), due to their special inheritance models, physical location on a single chromosome and the absence of recombination in male meiosis, play an important role in forensic and population genetics. While a series of genetic analyses focusing on the genetic diversity and forensic characteristics of X-STRs are well studied for ethnically/linguistically diverse and demographically large Chinese populations, genetic evidence from Gelao ethnicity is still sparse. Here, we genotyped the first batch of 19 X-STRs in 513 Chinese Gelao individuals (265 females and 248 males), and reported genetic polymorphisms, forensic characteristics based on the single locus and seven linkage groups. DXS10135 with the highest PIC (0.9106) and LG1 (DXS10148-DXS10135-DXS8378) with the largest HD (0.9970) are polymorphic and informative. The CPDs in Gelao males and females are respectively larger than 0.999999999997095 and 0.99999999999999999999918, and the combined MECs are larger than 0.999999975715109. Subsequently, we investigated the population relationships among 14 Chinese populations based on 19 X-STRs and among 23 populations based on 11 overlapped X-STRs. Our results revealed genetic differentiations among Tibeto-Burman, Altaic and other Chinese homogenous populations, and demonstrated that Guizhou Gelao has the genetically closer relationships with Han Chinese and geographically close Guizhou Miao. PMID- 30275509 TI - Calcium increases titin N2A binding to F-actin and regulated thin filaments. AB - Mutations in titin are responsible for many cardiac and muscle diseases, yet the underlying mechanisms remain largely unexplained. Numerous studies have established roles for titin in muscle function, and Ca2+-dependent interactions between titin and actin have been suggested to play a role in muscle contraction. The present study used co-sedimentation assays, dynamic force spectroscopy (DFS), and in vitro motility (IVM) assays to determine whether the N2A region of titin, overlooked in previous studies, interacts with actin in the presence of Ca2+. Co sedimentation demonstrated that N2A - F-actin binding increases with increasing protein and Ca2+ concentration, DFS demonstrated increased rupture forces and decreased koff in the presence of Ca2+, and IVM demonstrated a Ca2+-dependent reduction in motility of F-actin and reconstituted thin filaments in the presence of N2A. These results indicate that Ca2+ increases the strength and stability of N2A - actin interactions, supporting the hypothesis that titin plays a regulatory role in muscle contraction. The results further support a model in which N2A - actin binding in active muscle increases titin stiffness, and that impairment of this mechanism contributes to the phenotype in muscular dystrophy with myositis. Future studies are required to determine whether titin - actin binding occurs in skeletal muscle sarcomeres in vivo. PMID- 30275512 TI - Anaerobic nitrate reduction divergently governs population expansion of the enteropathogen Vibrio cholerae. AB - To survive and proliferate in the absence of oxygen, many enteric pathogens can undergo anaerobic respiration within the host by using nitrate (NO3-) as an electron acceptor1,2. In these bacteria, NO3- is typically reduced by a nitrate reductase to nitrite (NO2-), a toxic intermediate that is further reduced by a nitrite reductase3. However, Vibrio cholerae, the intestinal pathogen that causes cholera, lacks a nitrite reductase, leading to NO2- accumulation during nitrate reduction4. Thus, V. cholerae is thought to be unable to undergo NO3--dependent anaerobic respiration4. Here, we show that during hypoxic growth, NO3- reduction in V. cholerae divergently affects bacterial fitness in a manner dependent on environmental pH. Remarkably, in alkaline conditions, V. cholerae can reduce NO3- to support population growth. Conversely, in acidic conditions, accumulation of NO2- from NO3- reduction simultaneously limits population expansion and preserves cell viability by lowering fermentative acid production. Interestingly, other bacterial species such as Salmonella typhimurium, enterohaemorrhagic Escherichia coli (EHEC) and Citrobacter rodentium also reproduced this pH-dependent response, suggesting that this mechanism might be conserved within enteric pathogens. Our findings explain how a bacterial pathogen can use a single redox reaction to divergently regulate population expansion depending on the fluctuating environmental pH.

PMID- 30275513 TI - In vivo TssA proximity labelling during type VI secretion biogenesis reveals TagA as a protein that stops and holds the sheath. AB - The type VI secretion system (T6SS) is a multiprotein weapon used by bacteria to destroy competitor cells. The T6SS contractile sheath wraps an effector-loaded syringe that is injected into the target cell. This tail structure assembles onto the baseplate that is docked to the membrane complex. In enteroaggregative Escherichia coli, TssA plays a central role at each stage of the T6SS assembly pathway by stabilizing the baseplate and coordinating the polymerization of the tail. Here we adapted an assay based on APEX2-dependent biotinylation to identify the proximity partners of TssA in vivo. By using stage-blocking mutations, we define the temporal contacts of TssA during T6SS biogenesis. This proteomic mapping approach also revealed an additional partner of TssA, TagA. We show that TagA is a cytosolic protein tightly associated with the membrane. Analyses of sheath dynamics further demonstrate that TagA captures the distal end of the sheath to stop its polymerization and to maintain it under the extended conformation.

AB - Chaperone-usher pathway pili are extracellular proteinaceous fibres ubiquitously found on Gram-negative bacteria, and mediate host-pathogen interactions and biofilm formation critical in pathogenesis in numerous human diseases1. During pilus assembly, an outer membrane macromolecular machine called the usher catalyses pilus biogenesis from the individual subunits that are delivered as chaperone-subunit complexes in the periplasm. The usher orchestrates pilus assembly using all five functional domains: a 24-stranded transmembrane beta barrel translocation domain, a beta-sandwich plug domain, an amino-terminal periplasmic domain and two carboxy-terminal periplasmic domains (CTD1 and CTD2)2 6. Despite extensive structural and functional characterization, the mechanism by which the usher is activated to initiate pilus biogenesis is unknown. Here, we present the crystal structure of the full-length PapC usher from Escherichia coli in complex with its cognate PapDG chaperone-subunit complex in a pre-activation state, elucidating molecular details of how the usher is specifically engaged by allosteric interactions with its substrate preceding activation and how the usher facilitates the transfer of subunits from the amino-terminal periplasmic domain to the CTDs during pilus assembly. This work elucidates the intricate workings of a molecular machine that catalyses chaperone-usher pathway pilus assembly and opens the door for the development of potent inhibitors to block pilus biogenesis. PMID- 30275514 TI - Accelerating anticancer drug development - opportunities and trade-offs. AB - The traditional approach to drug development in oncology, with discrete phases of clinical testing, is becoming untenable owing to expansion of the precision medicine paradigm, whereby patients are stratified into multiple subgroups according to the underlying cancer biology. Seamless approaches to drug development in oncology hold great promise of accelerating the accessibility of novel therapeutic agents to the public but are also accompanied by important trade-offs, including the limited availability of information on the clinical benefit and safety of novel agents at the time of market entry. In this Perspectives article, we describe several opportunities, in the form of novel trial designs or modelling strategies, to improve the efficiency of drug development in oncology, as well as new mechanisms to obtain information about anticancer therapies throughout their life cycle, such as innovative functional imaging techniques or the use of real-world clinical data. PMID- 30275515 TI - Therapeutic strategies to target RAS-mutant cancers. AB - RAS genes are the most commonly mutated oncogenes in cancer, but effective therapeutic strategies to target RAS-mutant cancers have proved elusive. A key aspect of this challenge is the fact that direct inhibition of RAS proteins has proved difficult, leading researchers to test numerous alternative strategies aimed at exploiting RAS-related vulnerabilities or targeting RAS effectors. In the past few years, we have witnessed renewed efforts to target RAS directly, with several promising strategies being tested in clinical trials at different stages of completion. Important advances have also been made in approaches designed to indirectly target RAS by improving inhibition of RAS effectors, exploiting synthetic lethal interactions or metabolic dependencies, using therapeutic combination strategies or harnessing the immune system. In this Review, we describe historical and ongoing efforts to target RAS-mutant cancers and outline the current therapeutic landscape in the collective quest to overcome the effects of this crucial oncogene. PMID- 30275517 TI - NMD-degradome sequencing reveals ribosome-bound intermediates with 3'-end non templated nucleotides. AB - Nonsense-mediated messenger RNA decay (NMD) controls mRNA quality and degrades physiologic mRNAs to fine-tune gene expression in changing developmental or environmental milieus. NMD requires that its targets are removed from the translating pool of mRNAs. Since the decay steps of mammalian NMD remain unknown, we developed assays to isolate and sequence direct NMD decay intermediates transcriptome-wide based on their co-immunoprecipitation with phosphorylated UPF1, which is the active form of this essential NMD factor. We show that, unlike steady-state UPF1, phosphorylated UPF1 binds predominantly deadenylated mRNA decay intermediates and activates NMD cooperatively from 5'- and 3'-ends. We leverage method modifications to characterize the 3'-ends of NMD decay intermediates, show that they are ribosome-bound, and reveal that some are subject to the addition of non-templated nucleotide. Uridines are added by TUT4 and TUT7 terminal uridylyl transferases and removed by the Perlman syndrome associated exonuclease DIS3L2. The addition of other non-templated nucleotides appears to inhibit decay. PMID- 30275516 TI - DNA G-quadruplex structures mold the DNA methylome. AB - Control of DNA methylation level is critical for gene regulation, and the factors that govern hypomethylation at CpG islands (CGIs) are still being uncovered. Here, we provide evidence that G-quadruplex (G4) DNA secondary structures are genomic features that influence methylation at CGIs. We show that the presence of G4 structure is tightly associated with CGI hypomethylation in the human genome. Surprisingly, we find that these G4 sites are enriched for DNA methyltransferase 1 (DNMT1) occupancy, which is consistent with our biophysical observations that DNMT1 exhibits higher binding affinity for G4s as compared to duplex, hemi methylated, or single-stranded DNA. The biochemical assays also show that the G4 structure itself, rather than sequence, inhibits DNMT1 enzymatic activity. Based on these data, we propose that G4 formation sequesters DNMT1 thereby protecting certain CGIs from methylation and inhibiting local methylation. PMID- 30275520 TI - Making matters worse. PMID- 30275518 TI - Leukocyte telomere length and risk of gastric cardia adenocarcinoma. AB - As a chromosome stabilizer, telomeres play an essential part in maintaining the stability and integrity of human genome. Shortened telomeres have been associated with the development of cancers but it is still largely unclear whether leukocyte telomere length contributes to predisposition of gastric cardia adenocarcinoma (GCA). We conducted a case-control study consisting of 524 GCA cases and 510 controls to assess the association between telomere length in peripheral blood leukocytes and GCA risk in a Chinese Han population. The GCA patients had significantly overall shorter relative leukocyte telomere length (RTL) (median +/ SD: 1.10 +/- 0.54) when compared with the controls (1.24 +/- 0.58). Individuals with the shortest quartile of RTL performed a doubled GCA risk (OR = 2.18; 95% CI = 1.47-3.22, P = 9.90 * 10-5) when compared with those with the highest quartile. We also found that telomere shortening and smoking have a significantly synergistic effect in intensifying risk of GCA (OR = 7.03, 95% CI = 4.55-10.86, P = 1.43 * 10-18). These findings indicate that short RTL contributes to increased susceptibility of gastric cardia adenocarcinoma and might be a promising marker to identify high-risk individuals combined with lifestyle risk factors. PMID- 30275519 TI - Competition and dual users in complex contagion processes. AB - We study the competition of two spreading entities, for example innovations, in complex contagion processes in complex networks. We develop an analytical framework and examine the role of dual users, i.e. agents using both technologies. Searching for the spreading transition of the new innovation and the extinction transition of a preexisting one, we identify different phases depending on network mean degree, prevalence of preexisting technology, and thresholds of the contagion process. Competition with the preexisting technology effectively suppresses the spread of the new innovation, but it also allows for phases of coexistence. The existence of dual users largely modifies the transient dynamics creating new phases that promote the spread of a new innovation and extinction of a preexisting one. It enables the global spread of the new innovation even if the old one has the first-mover advantage. PMID- 30275521 TI - The majority is uncultured. PMID- 30275522 TI - Engineered mRNA-expressed antibodies prevent respiratory syncytial virus infection. AB - The lung is a critical prophylaxis target for clinically important infectious agents, including human respiratory syncytial virus (RSV) and influenza. Here, we develop a modular, synthetic mRNA-based approach to express neutralizing antibodies directly in the lung via aerosol, to prevent RSV infections. First, we express palivizumab, which reduces RSV F copies by 90.8%. Second, we express engineered, membrane-anchored palivizumab, which prevents detectable infection in transfected cells, reducing in vitro titer and in vivo RSV F copies by 99.7% and 89.6%, respectively. Finally, we express an anchored or secreted high-affinity, anti-RSV F, camelid antibody (RSV aVHH and sVHH). We demonstrate that RSV aVHH, but not RSV sVHH, significantly inhibits RSV 7 days post transfection, and we show that RSV aVHH is present in the lung for at least 28 days. Overall, our data suggests that expressing membrane-anchored broadly neutralizing antibodies in the lungs could potentially be a promising pulmonary prophylaxis approach. PMID- 30275524 TI - Changes in body composition and metabolic disease risk. AB - As individuals gain weight, they increase the amount of fat that they accrue on their body. This causes adipocytes to enlarge and increases not only subcutaneous fat but also deposits fat in other vulnerable areas of the body. This ectopic fat is deposited in the intra-abdominal visceral fat depot, in muscle, in the liver and in the beta cells. Fat in these locations initiates a dysfunctional state in these insulin-sensitive tissues leading to insulin resistance, the appearance of the Metabolic Syndrome, and an increased risk of developing both type 2 diabetes and cardiovascular disease. A loss of weight and with it a loss of fat decreases this risk. PMID- 30275523 TI - Expanded A-DROP Score: A New Scoring System for the Prediction of Mortality in Hospitalized Patients with Community-acquired Pneumonia. AB - There are several established prognostic scoring systems for community-acquired pneumonia (CAP). The Pneumonia Severity Index (PSI) is a prediction rule consisting of 20 variables to identify low-risk patients with CAP. Although PSI had high discrimination ability, it is complex to calculate and difficult to use in busy hospital settings. The CURB-65 score is much simpler to use than is PSI, but it has lower sensitivity for predicting mortality compared with PSI. The A DROP score is a modified version of the CURB-65 score and provides similar predictive power to that of CURB-65. This study was performed to determine whether a simpler score (CURB-65, A-DROP), expanded with a small number of additional variables, can predict mortality more accurately than PSI. We conducted a retrospective observational study of 1,031 patients with CAP who were hospitalized at a tertiary teaching hospital. We used age, sex, comorbidities, vital signs, and laboratory findings as prognostic variables. We compared the PSI, CURB-65, and A-DROP scores using receiver operating characteristic curve analysis. The areas under the curves (AUCs) of PSI, CURB-65, and A-DROP were 0.735, 0.701, and 0.730, respectively.Multivariable analysis identified malignancy [odds ratio (OR): 2.17, 95% confidence interval (CI): 1.13-4.17], respiration rate >= 24/min [OR: 2.18, 95% CI: 1.24-3.82], heart rate >= 100/min [OR: 2.92, 95% CI: 1.68-5.08], albumin <= 3.09 g/dL [OR: 3.85, 95% CI: 2.09 7.07], lactate > 1.7 mmol/L [OR: 2.59, 95% CI: 1.53-4.38], and N-terminal prohormone brain natriuretic peptide > 500 pg/mL [OR: 2.23, 95% CI: 1.26-3.95] as prognostic factors. Using the prognostic variables identified in the multivariable analysis, we assembled a new scoring system, the expanded A-DROP score. The AUC of this score for the prediction of 28-day mortality was 0.834 (95% CI: 0.794-0.874). Bootstrap validation yielded an estimated AUC of 0.833, indicating negligible overfitting of the model.The expanded A-DROP score is a relatively simple and effective scoring system, and its predictive value was superior to those of other scoring systems.

PMID- 30275526 TI - Cytogenetics and gene mutations influence survival in older patients with acute myeloid leukemia treated with azacitidine or conventional care. AB - Older patients with newly diagnosed acute myeloid leukemia (AML) in the phase 3 AZA-AML-001 study were evaluated at entry for cytogenetic abnormalities, and a subgroup of patients was assessed for gene mutations. Patients received azacitidine 75 mg/m2/day x7 days (n = 240) or conventional care regimens (CCR; n = 245): intensive chemotherapy, low-dose cytarabine, or best supportive care only. Overall survival (OS) was assessed for patients with common (occurring in >=10% of patients) cytogenetic abnormalities and karyotypes, and for patients with recurring gene mutations. There was a significant OS improvement with azacitidine vs CCR for patients with European LeukemiaNet-defined Adverse karyotype (HR 0.71 [95%CI 0.51-0.99]; P = 0.046). Azacitidine-treated patients with -5/5q-, -7/7q-, or 17p abnormalities, or with monosomal or complex karyotypes, had a 31-46% reduced risk of death vs CCR. The most frequent gene mutations were DNMT3A (27%), TET2 (25%), IDH2 (23% [R140, 15%; R172, 8%]), and TP53 (21%). Compared with wild-type, OS was significantly reduced among CCR treated patients with TP53 or NRAS mutations and azacitidine-treated patients with FLT3 or TET2 mutations. Azacitidine may be a preferred treatment for older patients with AML with Adverse-risk cytogenetics, particularly those with chromosome 5, 7, and/or 17 abnormalities and complex or monosomal karyotypes. The influence of gene mutations in azacitidine-treated patients warrants further study. PMID- 30275527 TI - Mlh1 deficiency increases the risk of hematopoietic malignancy after simulated space radiation exposure. AB - Cancer-causing genome instability is a major concern during space travel due to exposure of astronauts to potent sources of high-linear energy transfer (LET) ionizing radiation. Hematopoietic stem cells (HSCs) are particularly susceptible to genotoxic stress, and accumulation of damage can lead to HSC dysfunction and oncogenesis. Our group recently demonstrated that aging human HSCs accumulate microsatellite instability coincident with loss of MLH1, a DNA Mismatch Repair (MMR) protein, which could reasonably predispose to radiation-induced HSC malignancies. Therefore, in an effort to reduce risk uncertainty for cancer development during deep space travel, we employed an Mlh1+/- mouse model to study the effects high-LET 56Fe ion space-like radiation. Irradiated Mlh1+/- mice showed a significantly higher incidence of lymphomagenesis with 56Fe ions compared to gamma-rays and unirradiated mice, and malignancy correlated with increased MSI in the tumors. In addition, whole-exome sequencing analysis revealed high SNVs and INDELs in lymphomas being driven by loss of Mlh1 and frequently mutated genes had a strong correlation with human leukemias. Therefore, the data suggest that age-related MMR deficiencies could lead to HSC malignancies after space radiation, and that countermeasure strategies will be required to adequately protect the astronaut population on the journey to Mars. PMID- 30275529 TI - CRISPR-Cas9-mediated base-editing screening in mice identifies DND1 amino acids that are critical for primordial germ cell development. AB - CRISPR-mediated base editing can introduce single-nucleotide changes in the DNA of living cells. One intriguing application of base editing is to screen pivotal amino acids for protein function in vivo; however, it has not been achieved. Here, we report an enhanced third-generation base-editing system with extra nuclear localization sequences that can efficiently introduce a homozygous base mutation in embryonic stem cells. Meanwhile, we establish a strategy to generate base-mutant mice by injection of haploid embryonic stem cells carrying a constitutively expressed enhanced third-generation base-editing system (4B2N1) and single guide RNA into oocytes. Moreover, transfection of 4B2N1 cells with a single guide RNA library targeting the Dnd1 gene allows one-step generation of mutant mice with a base mutation. This enables the identification of four missense mutations that completely deplete primordial germ cells through disruption of DND1 protein stability and protein-protein interaction. Thus, our strategy provides an effective tool for in vivo screening of amino acids that are crucial for protein function. PMID- 30275528 TI - Sequential high-dose cytarabine and mitoxantrone (S-HAM) versus standard double induction in acute myeloid leukemia-a phase 3 study. AB - Dose-dense induction with the S-HAM regimen was compared to standard double induction therapy in adult patients with newly diagnosed acute myeloid leukemia. Patients were centrally randomized (1:1) between S-HAM (2nd chemotherapy cycle starting on day 8 = "dose-dense") and double induction with TAD-HAM or HAM(-HAM) (2nd cycle starting on day 21 = "standard"). 387 evaluable patients were randomly assigned to S-HAM (N = 203) and to standard double induction (N = 184). The primary endpoint overall response rate (ORR) consisting of complete remission (CR) and incomplete remission (CRi) was not significantly different (P = 0.202) between S-HAM (77%) and double induction (72%). The median overall survival was 35 months after S-HAM and 25 months after double induction (P = 0.323). Duration of critical leukopenia was significantly reduced after S-HAM (median 29 days) versus double induction (median 44 days)-P < 0.001. This translated into a significantly shortened duration of hospitalization after S-HAM (median 37 days) as compared to standard induction (median 49 days)-P < 0.001. In conclusion, dose dense induction therapy with the S-HAM regimen shows favorable trends but no significant differences in ORR and OS compared to standard double induction. S HAM significantly shortens critical leukopenia and the duration of hospitalization by 2 weeks. PMID- 30275532 TI - Damping of selectively bonded 3D woven lattice materials. AB - The objective of this paper is to unveil a novel damping mechanism exhibited by 3D woven lattice materials (3DW), with emphasis on response to high-frequency excitations. Conventional bulk damping materials, such as rubber, exhibit relatively low stiffness, while stiff metals and ceramics typically have negligible damping. Here we demonstrate that high damping and structural stiffness can be simultaneously achieved in 3D woven lattice materials by brazing only select lattice joints, resulting in a load-bearing lattice frame intertwined with free, 'floating' lattice members to generate damping. The produced material samples are comparable to polymers in terms of damping coefficient, but are porous and have much higher maximum use temperature. We shed light on a novel damping mechanism enabled by an interplay between the forcing frequency imposed onto a load-bearing lattice frame and the motion of the embedded, free-moving lattice members. This novel class of damping metamaterials has potential use in a broad range of weight sensitive applications that require vibration attenuation at high frequencies.

PMID- 30275531 TI - Genetics of blood lipids among ~300,000 multi-ethnic participants of the Million Veteran Program. AB - The Million Veteran Program (MVP) was established in 2011 as a national research initiative to determine how genetic variation influences the health of US military veterans. Here we genotyped 312,571 MVP participants using a custom biobank array and linked the genetic data to laboratory and clinical phenotypes extracted from electronic health records covering a median of 10.0 years of follow-up. Among 297,626 veterans with at least one blood lipid measurement, including 57,332 black and 24,743 Hispanic participants, we tested up to around 32 million variants for association with lipid levels and identified 118 novel genome-wide significant loci after meta-analysis with data from the Global Lipids Genetics Consortium (total n > 600,000). Through a focus on mutations predicted to result in a loss of gene function and a phenome-wide association study, we propose novel indications for pharmaceutical inhibitors targeting PCSK9 (abdominal aortic aneurysm), ANGPTL4 (type 2 diabetes) and PDE3B (triglycerides and coronary disease). PMID- 30275534 TI - Shining light on the significance of NK cell CD56 brightness. PMID- 30275530 TI - Sixteen diverse laboratory mouse reference genomes define strain-specific haplotypes and novel functional loci. AB - We report full-length draft de novo genome assemblies for 16 widely used inbred mouse strains and find extensive strain-specific haplotype variation. We identify and characterize 2,567 regions on the current mouse reference genome exhibiting the greatest sequence diversity. These regions are enriched for genes involved in pathogen defence and immunity and exhibit enrichment of transposable elements and signatures of recent retrotransposition events. Combinations of alleles and genes unique to an individual strain are commonly observed at these loci, reflecting distinct strain phenotypes. We used these genomes to improve the mouse reference genome, resulting in the completion of 10 new gene structures. Also, 62 new coding loci were added to the reference genome annotation. These genomes identified a large, previously unannotated, gene (Efcab3-like) encoding 5,874 amino acids. Mutant Efcab3-like mice display anomalies in multiple brain regions, suggesting a possible role for this gene in the regulation of brain development. PMID- 30275536 TI - IL-33 drives the antitumor effects of dendritic cells via the induction of Tc9 cells. AB - Dendritic cell (DC) tumor vaccines exert their antitumor effects through the induction of effector T cells. We recently identified Tc9 cells as a new potent antitumor effector T cell subset. However, approaches to direct DCs to preferably prime antitumor Tc9 cells should be further exploited. Here, we demonstrate that the addition of interleukin (IL)-33 potently promotes the induction of Tc9 cells by DCs in vitro and in vivo. IL-33 treatment also drives the cytotoxic activities of DC-induced Tc9 cells. Notably, IL-33 treatment enhances cell survival and proliferation of DC-primed CD8+ T cells. More importantly, the addition of IL-33 during in vitro priming of tumor-specific Tc9 cells by DCs increases the antitumor capability of Tc9 cells. Mechanistic studies demonstrated that IL-33 treatment inhibits exhaustive CD8+ T cell differentiation by inhibiting PD-1 and 2B4 expression and increasing IL-2 and CD127 (IL-7 receptor-alpha, IL-7Ralpha) expression in CD8+ T cells. Finally, the addition of IL-33 further promotes the therapeutic efficacy of DC-based tumor vaccines in the OT-I mouse model. Our study demonstrates the important role of IL-33 in DC-induced Tc9 cell differentiation and antitumor immunity and may have important clinical implications. PMID- 30275535 TI - E3 ligase FBXW7 aggravates TMPD-induced systemic lupus erythematosus by promoting cell apoptosis. AB - Systemic lupus erythematosus (SLE) is a systemic autoimmune disease, and the pathogenesis of SLE has not been fully elucidated. The E3 ubiquitin ligase FBXW7 has been well characterized in cancer as a tumor suppressor that can promote the ubiquitination and subsequent degradation of various oncoproteins; however, the potential role of FBXW7 in autoimmune diseases is unclear. In the present study, we identified that FBXW7 is a crucial exacerbating factor for SLE development and progression in a mouse model induced by 2, 6, 10, 14-tetramethylpentadecane (TMPD). Myeloid cell-specific FBXW7-deficient (Lysm+FBXW7f/f) C57BL/6 mice showed decreased immune complex accumulation, glomerulonephritis, glomerular mesangial cell proliferation, and base-membrane thickness in the kidney. Lysm+FBXW7f/f mice produced fewer anti-Sm/RNP and anti-ANA autoantibodies and showed a decreased MHC II expression in B cells. In Lysm+FBXW7f/f mice, we observed that cell apoptosis was reduced and that fewer CD11b+Ly6Chi inflammatory monocytes were recruited to the peritoneal cavity. Consistently, diffuse pulmonary hemorrhage (DPH) was also decreased in Lysm+FBXW7f/f mice. Mechanistically, we clarified that FBXW7 promoted TMPD-induced cell apoptosis by catalyzing MCL1 degradation through K48 linked ubiquitination. Our work revealed that FBXW7 expression in myeloid cells played a crucial role in TMPD-induced SLE progression in mice, which may provide novel ideas and theoretical support for understanding the pathogenesis of SLE. PMID- 30275538 TI - Targeting PVR (CD155) and its receptors in anti-tumor therapy. AB - Poliovirus receptor (PVR, CD155) has recently been gaining scientific interest as a therapeutic target in the field of tumor immunology due to its prominent endogenous and immune functions. In contrast to healthy tissues, PVR is expressed at high levels in several human malignancies and seems to have protumorigenic and therapeutically attractive properties that are currently being investigated in the field of recombinant oncolytic virotherapy. More intriguingly, PVR participates in a considerable number of immunoregulatory functions through its interactions with activating and inhibitory immune cell receptors. These functions are often modified in the tumor microenvironment, contributing to tumor immunosuppression. Indeed, increasing evidence supports the rationale for developing strategies targeting these interactions, either in terms of checkpoint therapy (i.e., targeting inhibitory receptors) or in adoptive cell therapy, which targets PVR as a tumor marker. PMID- 30275537 TI - NKR-P1B expression in gut-associated innate lymphoid cells is required for the control of gastrointestinal tract infections. AB - Helper-type innate lymphoid cells (ILC) play an important role in intestinal homeostasis. Members of the NKR-P1 gene family are expressed in various innate immune cells, including natural killer (NK) cells, and their cognate Clr ligand family members are expressed in various specialized tissues, including the intestinal epithelium, where they may play an important role in mucosal associated innate immune responses. In this study, we show that the inhibitory NKR-P1B receptor, but not the Ly49 receptor, is expressed in gut-resident NK cells, ILC, and a subset of gammadeltaT cells in a tissue-specific manner. ILC3 cells constitute the predominant cell subset expressing NKR-P1B in the gut lamina propria. The known NKR-P1B ligand Clr-b is broadly expressed in gut-associated cells of hematopoietic origin. The genetic deletion of NKR-P1B results in a higher frequency and number of ILC3 and gammadeltaT cells in the gut lamina propria. However, the function of gut-resident ILC3, NK, and gammadeltaT cells in NKR-P1B-deficient mice is impaired during gastrointestinal tract infection by Citrobacter rodentium or Salmonella typhimurium, resulting in increased systemic bacterial dissemination in NKR-P1B-deficient mice. Our findings highlight the role of the NKR-P1B:Clr-b recognition system in the modulation of intestinal innate immune cell functions. PMID- 30275539 TI - Methyltransferase Dot1l preferentially promotes innate IL-6 and IFN-beta production by mediating H3K79me2/3 methylation in macrophages. AB - Epigenetic modification, including histone modification, precisely controls target gene expression. The posttranscriptional regulation of the innate signaling-triggered production of inflammatory cytokines and type I interferons has been fully elucidated, whereas the roles of histone modification alteration and epigenetic modifiers in regulating inflammatory responses need to be further explored. Di/tri-methylation modifications of histone 3 lysine 79 (H3K79me2/3) have been shown to be associated with gene transcriptional activation. Disruptor of telomeric silencing-1-like (Dot1l) is the only known exclusive H3K79 methyltransferase and regulates the proliferation and differentiation of tumor cells. However, the roles of Dot1l and Dot1l-mediated H3K79 methylation in innate immunity and inflammatory responses remain unclear. Here, we found that H3K79me2/3 modification levels at the Il6 and Ifnb1 promoters, as well as H3K79me2 modification at the Tnfalpha promoter, were increased in macrophages activated by Toll-like receptor (TLR) ligands or virus infection. The innate signals upregulated Dot1l expression in macrophages and THP1 cells. Dot1l silencing or a Dot1l inhibitor preferentially suppressed the production of IL-6 and interferon (IFN)-beta but not of TNF-alpha in macrophages and THP1 cells triggered by TLR ligands or virus infection. Dot1l was recruited to the proximal promoter of the Il6 and Ifnb1 but not Tnfalpha gene and then mediated H3K79me2/3 modification at the Il6 and Ifnb1 promoters, consequently facilitating the transcription and expression of Il6 and Ifnb1. Thus, Dot1l-mediated selective H3K79me2/3 modifications at the Il6 and Ifnb1 promoters are required for the full activation of innate immune responses. This finding adds new insights into the epigenetic regulation of inflammatory responses and pathogenesis of autoimmune diseases. PMID- 30275540 TI - Coupled microbial bloom and oxygenation decline recorded by magnetofossils during the Palaeocene-Eocene Thermal Maximum. AB - Understanding marine environmental change and associated biological turnover across the Palaeocene-Eocene Thermal Maximum (PETM; ~56 Ma)-the most pronounced Cenozoic short-term global warming event-is important because of the potential role of the ocean in atmospheric CO2 drawdown, yet proxies for tracing marine productivity and oxygenation across the PETM are limited and results remain controversial. Here we show that a high-resolution record of South Atlantic Ocean bottom water oxygenation can be extracted from exceptionally preserved magnetofossils-the bioinorganic magnetite nanocrystals produced by magnetotactic bacteria (MTB) using a new multiscale environmental magnetic approach. Our results suggest that a transient MTB bloom occurred due to increased nutrient supply. Bottom water oxygenation decreased gradually from the onset to the peak PETM. These observations provide a record of microbial response to the PETM and establish the value of magnetofossils as palaeoenvironmental indicators. PMID- 30275541 TI - LISA improves statistical analysis for fMRI. AB - One of the principal goals in functional magnetic resonance imaging (fMRI) is the detection of local activation in the human brain. However, lack of statistical power and inflated false positive rates have recently been identified as major problems in this regard. Here, we propose a non-parametric and threshold-free framework called LISA to address this demand. It uses a non-linear filter for incorporating spatial context without sacrificing spatial precision. Multiple comparison correction is achieved by controlling the false discovery rate in the filtered maps. Compared to widely used other methods, it shows a boost in statistical power and allows to find small activation areas that have previously evaded detection. The spatial sensitivity of LISA makes it especially suitable for the analysis of high-resolution fMRI data acquired at ultrahigh field (>=7 Tesla). PMID- 30275542 TI - Higher ambient synaptic glutamate at inhibitory versus excitatory neurons differentially impacts NMDA receptor activity. AB - Selective disruption of synaptic drive to inhibitory neurons could contribute to the pathophysiology of various brain disorders. We have previously identified a GluN2A-selective positive allosteric modulator, GNE-8324, that selectively enhances N-methyl-D-aspartate receptor (NMDAR)-mediated synaptic responses in inhibitory but not excitatory neurons. Here, we demonstrate that differences in NMDAR subunit composition do not underlie this selective potentiation. Rather, a higher ambient glutamate level in the synaptic cleft of excitatory synapses on inhibitory neurons is a key factor. We show that increasing expression of glutamate transporter 1 (GLT-1) eliminates GNE-8324 potentiation in inhibitory neurons, while decreasing GLT-1 activity enables potentiation in excitatory neurons. Our results reveal an unsuspected difference between excitatory synapses onto different neuronal types, and a more prominent activation of synaptic NMDARs by ambient glutamate in inhibitory than excitatory neurons. This difference has implications for tonic NMDAR activity/signaling and the selective modulation of inhibitory neuron activity to treat brain disorders. PMID- 30275543 TI - A flow platform for degradation-free CuAAC bioconjugation. AB - The Cu-catalyzed azide-alkyne cycloaddition (CuAAC) reaction is a cornerstone method for the ligation of biomolecules. However, undesired Cu-mediated oxidation and Cu-contamination in bioconjugates limits biomedical utility. Here, we report a generic CuAAC flow platform for the rapid, robust, and broad-spectrum formation of discrete triazole bioconjugates. This process leverages an engineering problem to chemical advantage: solvent-mediated Cu pipe erosion generates ppm levels of Cu in situ under laminar flow conditions. This is sufficient to catalyze the CuAAC reaction of small molecule alkynes and azides, fluorophores, marketed drug molecules, peptides, DNA, and therapeutic oligonucleotides. This flow approach, not replicated in batch, operates at ambient temperature and pressure, requires short residence times, avoids oxidation of sensitive functional groups, and produces products with very low ppm Cu contamination. PMID- 30275544 TI - Transmission infrared spectroscopy for rapid quantification of fat, protein, and lactose concentrations in human milk. AB - OBJECTIVE: To develop partial least squares regression (PLSR) calibration models in combination with transmission infrared (TIR) spectroscopy for rapid and optimal quantification of human milk macronutrient concentrations. STUDY DESIGN: Human milk samples (n = 306) were characterized simultaneously by reference chemical analytical methods and TIR spectroscopy. Reference macronutrient concentrations were linked to pre-processed spectra and divided into two (training and test) sets. PLSR was used to develop trial calibration models using training set, and the test set was used to assess the accuracy of the trial analytical methods. RESULTS: For the methods selected as optimal, the concordance correlation coefficients between reference and TIR-based methods were 0.93 for fat, 0.96 for protein, and 0.52 for lactose. The Bland-Altman plots showed no evidence of systematic bias between TIR and reference methods. CONCLUSIONS: TIR spectroscopy provides the basis for accurate and rapid quantification of human milk fat and protein concentrations but is less accurate for measuring lactose concentration. PMID- 30275545 TI - Outcomes of early inhaled nitric oxide use in premature African American neonates. AB - OBJECTIVE: Meta-analysis of individual-patient clinical trial data suggests that inhaled nitric oxide (iNO) improves respiratory outcomes in premature African American neonates. We hypothesized that early iNO therapy would be associated with lower mortality and less chronic lung disease (CLD) in extremely premature African American neonates. STUDY DESIGN: We conducted a retrospective cohort study of propensity score- and race-matched neonates 22-29 weeks gestation who were mechanically ventilated for treatment of respiratory distress and associated pulmonary hypertension (RDS + PPHN). We evaluated the association of iNO within 7 days of life with in-hospital mortality and CLD, using Cox proportional hazards regression and logistic regression, respectively. RESULT: Among 178 matched pairs of African American patients, iNO was not associated with lower mortality (HR = 0.94, 95% CI 0.69-1.30) or less CLD (OR = 0.94, 95% CI 0.47-1.87). CONCLUSIONS: Early, off-label iNO use is not associated with improved outcomes in premature African American neonates with RDS + PPHN.

AB - Characterizing the molecular immune subtype and micro-environment of lung cancer is necessary to understand immunogenic interactions between infiltrating immune and stromal cells, and how tumor cells overcome immune checkpoint blockades. This study seeks to identify computational methodologies for subtyping gene expression based tumor-immune micro-environment interactions, which differentiate non-small cell lung cancer (NSCLC) into immune-defective and immune-competent subtypes. Here, 101 lung squamous cell carcinomas (LUSCs) and 87 lung adenocarcinomas (LUADs) tumor samples have been analyzed. Several micro-environmental factors differentially induce LUAD or LUSC immune subtypes, as well as immune checkpoint expression. In particular, tumor-associated macrophages (TAMs) are key immune cells play a vital role in inflammation and cancer micro-environments of LUSCs; whereas, regulatory B cells are immunosuppressive and tumorigenic in LUADs. Additionally, cytolytic activity upon CD8+ T cell activation is decreased by the abundance of B cells and macrophages in immune-competent subtypes. Therefore, identifying immune subtypes in lung cancer and their impact on tumor micro environment will lead to clinical tools for assessing LUADs and LUSCs in patients, as well as maximize the efficacy of immune checkpoint inhibitors.

PMID- 30275547 TI - The de novo design of a biocompatible and functional integral membrane protein using minimal sequence complexity. AB - The de novo design of integral membrane proteins remains a major challenge in protein chemistry. Here, we describe the bottom-up design of a genetically encoded synthetic membrane protein comprising only four amino acids (L, S, G and W) in the transmembrane domains. This artificial sequence, which we call REAMP for recombinantly expressed artificial membrane protein, is a single chain of 133 residues arranged into four antiparallel membrane-spanning alpha-helices. REAMP was overexpressed in Escherichia coli and localized to the cytoplasmic membrane with the intended transmembrane topology. Recombinant REAMP could be extracted from the cell membrane in detergent micelles and was robust and stable in vitro, containing helical secondary structure consistent with the original design. Engineered mono- and bis-histidine residues in the membrane domain of REAMP were able to coordinate heme in vitro, in a manner reminiscent of natural b-type cytochromes. This binding shifted the electrochemical potential of the cofactor, producing a synthetic hemoprotein capable of nascent redox catalysis. These results show that a highly reduced set of amino acids is sufficient to mimic some key properties of natural proteins, and that cellular biosynthesis is a viable route for the production of minimal de novo membrane sequences.

PMID- 30275562 TI - XIAP facilitates breast and colon carcinoma growth via promotion of p62 depletion through ubiquitination-dependent proteasomal degradation. AB - X-linked inhibitor of apoptosis protein (XIAP) possesses a critical role in promotion of cell survival and maintenance of cellular homeostasis. In cancer, elevated XIAP expression has been associated with malignancy, poor prognosis, and treatment resistance. However, the underlying mechanisms of these effects remain unclear. XIAP has previously been proposed to promote tumor growth through suppression of autophagy. In this study, we examined the expression of XIAP and p62, two critical mediators of autophagy, in breast and colon cancer. We observed a negative correlation between XIAP and p62 expression in normal and cancer tissues of breast and colon, and that the ratio of XIAP and p62 expression determines the cancer phenotype. In vitro, we observed that XIAP interacted with p62 and also that XIAP depletion resulted in increased expression of p62. XIAP functioned as an ubiquitination E3 ligase towards p62 and suppressed p62 expression through ubiquitin-proteasomal degradation. Furthermore, XIAP enhanced cancer cell proliferation, viability, and colony formation in vitro via suppression of p62. In addition, we demonstrated that XIAP-enhanced tumor growth is dependent on depletion of p62 in vivo. Herein, we have therefore delineated a novel mechanism by which XIAP contributes to development and progression of breast and colon carcinoma. PMID- 30275563 TI - Julia Randall Weertman (1926-2018). PMID- 30275564 TI - Topological quantum properties of chiral crystals. AB - Chiral crystals are materials with a lattice structure that has a well-defined handedness due to the lack of inversion, mirror or other roto-inversion symmetries. Although it has been shown that the presence of crystalline symmetries can protect topological band crossings, the topological electronic properties of chiral crystals remain largely uncharacterized. Here we show that Kramers-Weyl fermions are a universal topological electronic property of all non magnetic chiral crystals with spin-orbit coupling and are guaranteed by structural chirality, lattice translation and time-reversal symmetry. Unlike conventional Weyl fermions, they appear at time-reversal-invariant momenta. We identify representative chiral materials in 33 of the 65 chiral space groups in which Kramers-Weyl fermions are relevant to the low-energy physics. We determine that all point-like nodal degeneracies in non-magnetic chiral crystals with relevant spin-orbit coupling carry non-trivial Chern numbers. Kramers-Weyl materials can exhibit a monopole-like electron spin texture and topologically non trivial bulk Fermi surfaces over an unusually large energy window. PMID- 30275565 TI - Oxidation states and ionicity. AB - The concepts of oxidation state and atomic charge are entangled in modern materials science. We distinguish between these quantities and consider their fundamental limitations and utility for understanding material properties. We discuss the nature of bonding between atoms and the techniques that have been developed for partitioning electron density. While formal oxidation states help us count electrons (in ions, bonds, lone pairs), variously defined atomic charges are usefully employed in the description of physical processes including dielectric response and electronic spectroscopies. Such partial charges are introduced as quantitative measures in simple mechanistic models of a more complex reality, and therefore may not be comparable or transferable. In contrast, oxidation states are defined to be universal, with deviations constituting exciting challenges as evidenced in mixed-valence compounds, electrides and highly correlated systems. This Perspective covers how these concepts have evolved in recent years, our current understanding and their significance.

PMID- 30275566 TI - Renal compartment-specific genetic variation analyses identify new pathways in chronic kidney disease. AB - Chronic kidney disease (CKD), a condition in which the kidneys are unable to clear waste products, affects 700 million people globally. Genome-wide association studies (GWASs) have identified sequence variants for CKD; however, the biological basis of these GWAS results remains poorly understood. To address this issue, we created an expression quantitative trait loci (eQTL) atlas for the glomerular and tubular compartments of the human kidney. Through integrating the CKD GWAS with eQTL, single-cell RNA sequencing and regulatory region maps, we identified novel genes for CKD. Putative causal genes were enriched for proximal tubule expression and endolysosomal function, where DAB2, an adaptor protein in the TGF-beta pathway, formed a central node. Functional experiments confirmed that reducing Dab2 expression in renal tubules protected mice from CKD. In conclusion, compartment-specific eQTL analysis is an important avenue for the identification of novel genes and cellular pathways involved in CKD development and thus potential new opportunities for its treatment. PMID- 30275568 TI - Induction of resistance to chimeric antigen receptor T cell therapy by transduction of a single leukemic B cell. AB - We report a patient relapsing 9 months after CD19-targeted CAR T cell (CTL019) infusion with CD19- leukemia that aberrantly expressed the anti-CD19 CAR. The CAR gene was unintentionally introduced into a single leukemic B cell during T cell manufacturing, and its product bound in cis to the CD19 epitope on the surface of leukemic cells, masking it from recognition by and conferring resistance to CTL019. PMID- 30275569 TI - Genetic mechanisms of target antigen loss in CAR19 therapy of acute lymphoblastic leukemia. AB - We identified genetic mutations in CD19 and loss of heterozygosity at the time of CD19- relapse to chimeric antigen receptor (CAR) therapy. The mutations are present in the vast majority of resistant tumor cells and are predicted to lead to a truncated protein with a nonfunctional or absent transmembrane domain and consequently to a loss of surface antigen. This irreversible loss of CD19 advocates for an alternative targeting or combination CAR approach. PMID- 30275571 TI - A detector for the sources. PMID- 30275570 TI - Dynamics of genetically engineered hematopoietic stem and progenitor cells after autologous transplantation in humans. AB - Hematopoietic stem and progenitor cells (HSPC) are endowed with the role of generating and maintaining lifelong the extremely diverse pool of blood cells1. Clinically, transplantation of human HSPC from an allogeneic healthy donor or infusion of autologous gene-corrected HSPC can effectively replenish defective blood cell production caused by congenital or acquired disorders2-9. However, due to methodological and ethical constraints that have limited the study of human HSPC primarily to in vitro assays10 or xenotransplantation models11,12, the in vivo activity of HSPC has to date remained relatively unexplored in humans13-16. Here we report a comprehensive study of the frequencies, dynamics and output of seven HSPC subtypes in humans that was performed by tracking 148,093 individual clones in six patients treated with lentiviral gene therapy using autologous HSPC transplantation and followed for up to 5 years. We discovered that primitive multipotent progenitor and hematopoietic stem cell (HSC) populations have distinct roles during the initial reconstitution after transplant, compared with subsequent steady-state phases. Furthermore, we showed that a fraction of in vitro-activated HSC are resilient and undergo a defined delayed activation period upon transplant. Finally, our data support the concept that early lymphoid-biased progenitors might be capable of long-term survival, such that they can be maintained independently of their continuous production from HSC. Overall, this study provides comprehensive data on HSPC dynamics after autologous transplantation and gene therapy in humans. PMID- 30275572 TI - Single-particle analysis for fluorescence nanoscopy.

AB - Optical assays of synaptic strength could facilitate studies of neuronal transmission and its dysregulation in disease. Here we introduce a genetic toolbox for all-optical interrogation of synaptic electrophysiology (synOptopatch) via mutually exclusive expression of a channelrhodopsin actuator and an archaerhodopsin-derived voltage indicator. Optically induced activity in the channelrhodopsin-expressing neurons generated excitatory and inhibitory postsynaptic potentials that we optically resolved in reporter-expressing neurons. We further developed a yellow spine-targeted Ca2+ indicator to localize optogenetically triggered synaptic inputs. We demonstrated synOptopatch recordings in cultured rodent neurons and in acute rodent brain slice. In synOptopatch measurements of primary rodent cultures, acute ketamine administration suppressed disynaptic inhibitory feedbacks, mimicking the effect of this drug on network function in both rodents and humans. We localized this action of ketamine to excitatory synapses onto interneurons. These results establish an in vitro all-optical model of disynaptic disinhibition, a synaptic defect hypothesized in schizophrenia-associated psychosis.

AB - The accuracy of X-ray diffraction data is directly related to how the X-ray detector records photons. Here we describe the application of a direct-detection charge-integrating pixel-array detector (JUNGFRAU) in macromolecular crystallography (MX). JUNGFRAU features a uniform response on the subpixel level, linear behavior toward high photon rates, and low-noise performance across the whole dynamic range. We demonstrate that these features allow accurate MX data to be recorded at unprecedented speed. We also demonstrate improvements over previous-generation detectors in terms of data quality, using native single wavelength anomalous diffraction (SAD) phasing, for thaumatin, lysozyme, and aminopeptidase N. Our results suggest that the JUNGFRAU detector will substantially improve the performance of synchrotron MX beamlines and equip them for future synchrotron light sources.

AB - AIM: To retrospectively evaluate the technical features, feasibility, efficacy, accuracy and appropriate complications of CT-guided biopsies of mediastinal masses and correlate them with anatomical relationships in the mediastinum. METHODS: Over the course of ten years, 81 percutaneous biopsy procedures in 78 patients for tumors sizes 27 - 189 mm in diameter (median length 57.5 mm) were performed using only local anesthesia. These interventions were done under the guidance of computed tomography. The patients were men in 30 cases and women in 48 cases, aged 19 to 90 years. RESULTS: In 78 cases (96.3%) results were either true positive or true negative; in only 3 cases (3.7%, 3 biopsies of 2 tumors in 2 patients) were histological findings false negative. In 2.3% of the patients, complications were revealed in the anterior part of the mediastinum, 43.7% occurred in the middle region, and 14.3% in the posterior region of the mediastinum. Statistical data analysis verified there was a 3.74 times chance of an increase in complications in the middle mediastinal section in correlation with other anatomical localizations. In only one case was therapeutic intervention for complication necessary. For all other cases, a conservative approach was suitable. CONCLUSION: Percutaneous CT guided biopsies of the mediastinal tumors has a high accuracy rate in establishing the correct diagnosis. Masses in the middle mediastinum are associated with statistically higher incidences of postprocedural complications, which are not serious. PMID- 30275597 TI - Genetic architecture of recent-onset dilated cardiomyopathy in Moravian region assessed by whole-exome sequencing and its clinical correlates. AB - AIMS: Recent-onset dilated cardiomyopathy (RODCM) is a disease of heterogeneous aetiology and clinical outcome. In this pilot study, we aimed to assess its genetic architecture and correlate genotype with left ventricular reverse remodelling (LVRR). PATIENTS AND METHODS: In this multi-centre prospective observational study, we enrolled 83 Moravian patients with RODCM and a history of symptoms of less than 6 months, for whole-exome sequencing (WES). All patients underwent 12-month clinical and echocardiographic follow-up. LVRR was defined as an absolute increase in left ventricular ejection fraction > 10% accompanied by a relative decrease of left ventricular end-diastolic diameter > 10% at 12 months. RESULTS: WES identified at least one disease-related variant in 45 patients (54%). LVRR occurred in 28 patients (34%), most often in carriers of isolated titin truncated variants, followed by individuals with a negative, or inconclusive WES and carriers of other disease-related variants (56% vs. 42% vs. 19%, P=0.041). CONCLUSION: A substantial proportion of RODCM cases have a monogenic or oligogenic genetic background. Carriers of non-titin disease-related variants are less likely to reach LVRR at 12- months than other individuals. Genetic testing could contribute to better prognosis prediction and individualized treatment of RODCM. PMID- 30275599 TI - On Being a Catholic Palliative Medicine Physician.

AB - A new near-infrared fluorescent probe (NIR-PbP) for sensitive detection of Pb(II) ions in solution and living cells has been rationally designed and synthesized. The NIR-PbP is inherently non-fluorescent and gains fluorescence in the presence Pb(II) ions. The ion detection is based on Pb(II)-induced unmasking the fluorophore through the opening of the spyrocycle, with more than 500-fold fluorescence for sub-micromolar Pb(II) concentration. The NIR-PbP has high sensitivity, good photo-stability, low detection limit, and reversible response to Pb(II) ions. PMID- 30275600 TI - Practicing Medicine in Light of the Gospel.

The following is a reflection by one male obstetrician-gynecologist who considers the role of Saint Joseph in the holy family in contemplating his own role in providing women's health care. Summary: One hundred twenty-five men who underwent therapy trying to change sexual orientation from homosexual to heterosexual were asked about negative and positive experiences. About two-thirds recorded changes of varying extent. There was also much decrease in suicidality, depression, and substance abuse, and increases in social functioning and self-esteem. Almost all harmful effects were none to slight and comparable to therapies for other unwelcome conditions.

PMID- 30275603 TI - The Embrace of the Proabortion Turnaway Study: Wishful Thinking? or Willful Deceptions? AB - The abortion advocacy group Advancing New Standards in Reproductive Health (ANSIRH) has published over twenty papers based on a case series of women taking part in their Turnaway Study. Following the lead of ANSIRH news releases, major media outlets have described these results as proof that (a) most women who have abortions are glad they did, (b) there is no evidence of negative mental health effects following abortion, and (c) the only women really suffering are those who are being denied late-term abortions due to legal restrictions based on gestational age. Buried in ANSIRH's papers are the facts that over 68 percent of the women they sought to interview refused, their own evidence confirms that the remnant who did participate were atypical, there are no known benefits from abortion, their methods are misleadingly described, and their results are selectively reported. Summary: Widely publicized claims regarding the benefits of abortion for women have been discredited. The Turnaway Study, conducted by abortion advocates at thirty abortion clinics, reportedly proves that 95 percent of women have no regrets about their abortions and that abortion causes no mental health problems. But a new expose reveals that the authors have misled the public, using an unrepresentative, highly biased sample and misleading questions. In fact, over two-thirds of the women approached at the abortion clinics refused to be interviewed, and half of those who agreed dropped out. Refusers and dropouts are known to have more postabortion problems. PMID- 30275605 TI - Engage or Run: Reflections on My Intern Year.

PMID- 30275609 TI - Treatment of an Ectopic Pregnancy: An Ethical Reanalysis. AB - There is considerable lack of clarity on the medical facts surrounding management of ectopic pregnancy. In particular, it is not widely appreciated that by the time an ectopic pregnancy is diagnosed, in most cases, there is no viable fetus (i.e., the fetus has already died). Moreover, there is very little ethical guidance from the medical profession regarding the emotionally difficult decision to terminate a wanted pregnancy when the life of the mother is at risk. The best articulated positions on this topic come from religious groups, based on the principle of double effect. Yet the application of this reasoning to termination of an ectopic pregnancy is inconsistent with the medical facts in many cases. To resolve these inconsistencies, while still providing a robust ethical context for resolving such difficult situations, we propose clear guidelines for determining when a viable fetus is present in ectopic pregnancy and clarify the moral object in ectopic pregnancy management. Summary: This paper explores the ethical framework for clinical decision making in the case of ectopic pregnancies. Focusing on the disordered union of mother and unborn child clarifies the object and purpose of the actions used to separate the mother and fetus in order to save the life of both, or at least one. Since over 90% of tubal ectopic pregnancies present as embryos who have already died, these cases present no ethical dilemma. This paper proposes a modification of currently used criteria for determining the viability of ectopic pregnancies and calls for further research.

AB - Hereditary breast ovarian cancer (HBOC) syndrome is an autosomal dominant disease linked to mutations in the BRCA1 and BRCA2 genes in 90 percent of affected families. Female mutation carriers are highly susceptible to aggressive, often disseminated, usually fatal pelvic-abdominal carcinomatosis. This cancer risk can be markedly reduced by surgical removal of the internal gynecologic organs before the end of the fourth decade of life and by using estrogen-progestin formulations marketed for many years as combined oral contraceptives (COCs). Both risk reducing methods are associated with unfavorable effects. Relying on the principle of double effect, this essay argues for the ethical justification of prophylactic surgery and the use of COC to reduce the risk of gynecologic cancer in HBOC syndrome mutation carriers.

PMID- 30275610 TI - The Ethics of Interstitial and Cesarean Scar Ectopic Pregnancies: Four Case Studies and a Review of the Literature. AB - Catholic bioethicists have extensively addressed extrauterine tubal pregnancies, which represent the great majority of ectopic pregnancies. However, additional management options have been developed for the other 7-10 percent of ectopic pregnancies. Using two cases of interstitial pregnancy and two cases of cesarean scar pregnancy (CSP) seen at a Catholic tertiary care center, this article discusses options including expectant management, systemic methotrexate, intragestational methotrexate, intragestational potassium chloride, uterine artery embolization, dilation and curettage (D&C), vasopressin use, cornuostomy, cornual wedge resection, CSP evacuation, CSP scar excision, CSP salvage, and hysterectomy. Cornual wedge resection, vasopressin use, and CSP scar excision are morally acceptable; less clearly licit are aspiration of gestational sac contents, cornuostomy, gestational excision for CSPs, and methotrexate. Certainly illicit are any techniques leading to direct abortion such as D&Cs on live embryos or fetuses, double-balloon catheter placement, and use of potassium chloride. Summary: An ectopic pregnancy is any pregnancy outside the uterus. These are dangerous because the pregnancy can burst out of its abnormal location and cause life-threatening internal bleeding. Most are in the part of the fallopian tube outside the uterus, but there are other types, including interstitial pregnancies (located in the part of the tube tunneling through the uterine wall) and cesarean scar pregnancies (buried in the uterine scar where the cut for a C-section was made). This article lists the ways that physicians prevent women from dying from interstitial and cesarean scar pregnancies and proposes which treatments are morally acceptable.

AB - Background: Parents have a tremendous influence on their children's academic and social success. Unfortunately, a majority of them do not have a concrete idea on how to assist their children, impacting negatively on both the parents and the child. Currently, there is sparse research on parents' experiences in dealing with children with specific learning disorders (SLD). The current study was planned to explore the perception of families of children with SLD. Materials and Methods: Five focus group discussions (FGDs) including 30 parents of children with SLD aged between 8 and 14 years were carried out. Each group composed of five - seven participants. A format to guide FGDs was made to bring uniformity across groups. The transcripts were analyzed using the content analysis method to extract key conceptual themes. Results: The parents showed lack of conceptual knowledge with regard to the SLD symptomatology as well as proper guidelines to deal with their child's problem. They displayed negative attitudes and reactions toward their child's diagnosis of SLD, such as rejection, denial, over protection, and loss of hope. Their caregiving was also perceived to place physical, personal, social, financial, and emotional burden by the majority of parents. Conclusion: The study highlights the experiences of parents dealing with SLD in terms of their inadequate knowledge, adaptational difficulties, and burden. The findings also reiterate the need to focus on family perspective and experiences when working with a learning-disabled child. Various supportive strategies are required to empower families, which would help alleviate their burden. Moreover, parents' training to strengthen child's learning skills is also warranted. PMID- 30275615 TI - Children's Reactions to Flood Disaster in Kashmir. AB - Background: The flood disaster of 9th-10th September 2014 wreaked havoc in the Jammu and Kashmir region of India. Incessant rains and deluge claimed 283 lives and damaged 2.53 lakh houses. This article presents the findings of the psychosocial care team from the National Institute of Mental Health and Neuro Sciences, Bengaluru, India, during the early phase of disaster. Materials and Methods: The team assessed posttraumatic stress symptoms of 64 child survivors from six villages of two districts struck by floods using Children's Revised Impact of Event Scale (CRIES)-8 and qualitative narrations. Results: Children showed high levels of intrusion and avoidance in the aftermath of floods. Both boys and girls showed moderate to severe level of psychological impact on the domains of CRIES-8. The narrations by the children centred on the theme of "water" and "enjoyment in seeing lots of water;" followed by "fearing of the parent's life," later on "fear of their own life," and subsequently to avoidance to go near the river and nightmares like "floating in the water." Conclusion: Disasters immensely impact children because of their particular stage of psychological and social development. This highlights the need for psychosocial interventions to minimize the impact of disasters on children at the earliest using simple psychosocial care techniques by employing available community-based manpower. PMID- 30275616 TI - Adaptation of Subtests of Kaufman Assessment Battery for Children, Second Edition for Gujarati Pre-school Children. AB - Context: Cognition testing is frequently used in children to assess their intelligence for various needs. Abundant tests to assess cognition are available in the western world. The paucity of such tests for use in Gujarati population necessitates their adaptation for Gujarati culture. Aims: To adapt three subtests (Number Recall, Word Order, and Triangles) of Kaufman Assessment Battery for Children, Second Edition for Gujarati-speaking preschool age children using priori (judgemental) procedures of test adaptation process. Settings and Design: This was a prospective study of test adaptation process carried out in three kindergarten schools of Gujarat. Subjects and Methods: Three subtests were translated and adapted into Gujarati. A pilot study evaluating the applicability and appropriateness of the adapted version of the three tests was done, and the results of these raw scores were compared with English tests' scores. Of 68 children (age 3-6 years) who completed the pilot study, 15 boys and 15 girls 4-6 years of age were randomly selected to perform English tests for agreement between English and the adapted versions. Statistical Analysis Used: Agreement between the adapted and English versions of the tests was measured. Results: During adaptation, modifications were required only in the items of the Word order subtest. All children were able to understand and perform the test. Triangles did not require adaptation or modifications in test items. The agreement between raw scores of the two versions was good for both "Number Recall" (mean difference = 0.8, 95% confidence limits: -2.6, 4.1) and "Word Order" (mean difference = 0.6, 95% confidence limits: -3.2, 4.4). Conclusion: Adaptation of three subtests of KABC-II using a priori, that is, judgemental, procedure was suitable for Gujarati-speaking preschool children. PMID- 30275617 TI - Leisure Time Physical Activity and Risk of Developing Depression among the Youth of Kangra District, Himachal Pradesh, India. AB - Background: Physical inactivity during adolescence and youth has been considered as potential risk factor for future mental health problems. The present study was conducted with the aim to examine whether an association exists between leisure time physical activity (PA) and depression among the youth of Kangra district, studying in professional or degree colleges. Methodology: A cross-sectional study was conducted among the students of Medical College (MC), Central University (CU) and Industrial Training Institute (ITI) of Kangra district. 370 adolescents and youth of age <25 years, who consented to participate, were recruited. The sample size was divided into three parts among all the three institutes. Only one question regarding leisure time PA (LTPA) was asked, as to how many hours spent in the last week; and Center for Epidemiologic Studies Depression Scale for Children (CES-DC) was used. Results: There were 124 participants from ITI, 126 from CU and 120 from MC. The mean score of CES-DC was highest among CU students 22.7 (+/-11.0) and lowest among MC students; 13.6 (+/-9.2). Low LTPA (<4 h) was significantly associated with higher depressive symptoms among all students (odds ratio [95% confidence interval]; 3.34 [1.41-7.92]). Conclusion: LTPA was associated with lower rates of depression. PMID- 30275618 TI - What Adolescent Girls Know about Mental Health: Findings from a Mental Health Literacy Survey from an Urban Slum Setting in India. AB - Background: Youth in vulnerable situations are known to have high rates of mental disorders but low help-seeking. Help-seeking is known to be influenced by mental health literacy (MHL), a key concept that is important for the recognition of mental disorders and planning intervention. Aims: To explore MHL and help-seeking patterns in a group of young women in an urban slum setting in India. Materials and Methods: A total of 337 young women between 16 and 19 years of age belonging to urban slum settings formed the study sample. Two vignettes on depression and self-harm were used to assess: (a) recognition of the disorder, (b) help-seeking, and (c) knowledge of treatments available. Results: Only 8% of women were able to label the condition as depression in the first vignette. Though suicidality was identified correctly by the majority of participants 73 (63%), they did not think it needed urgent intervention. Only a few considered mental health professionals as possible sources of help (19.3% for depression and 2.4% for self-harm). Majority of the young women felt friends and parents were sources of help, and that stigma and lack of awareness were the reasons for not considering professional help. Conclusion: MHL regarding depression and suicidality is low among young women from low-income areas. It is a critical and urgent need to encourage early and appropriate help-seeking for mental health problems in this vulnerable population. PMID- 30275619 TI - Prevalence and Pattern of Phantom Ringing and Phantom Vibration among Medical Interns and their Relationship with Smartphone Use and Perceived Stress. AB - Background: Phantom sensations like phantom vibration (PV) and phantom ringing (PR)- the sensations of vibration and ringing of the phone when they are not, respectively-are among the latest in the category of "techno-pathology" to receive global attention. This study was conducted with the aim to estimate the prevalence of such sensations among medical interns and their association with perceived stress levels and smartphone usage pattern. Materials and Methods: Ninety-three medical interns using smartphone were recruited for the study. Data were collected anonymously using semi-structured questionnaire, perceived stress scale (PSS), and smartphone addiction scale-short version (SAS-SV). Data were analyzed using descriptive statistics, Chi-square test, independent t-test, ANOVA, and Pearson's correlation coefficient. Results: Fifty-nine percent students had a high level of stress, whereas 40% had problematic smartphone use. Sixty percent students experienced PV, whereas 42% experienced PR and both were significantly associated with higher frequency of phone use and the use of vibration mode. Mean SAS-SV score was significantly lower in students who did not perceive PR/PV, whereas mean PSS score was significantly lower in students who did not perceive PV. Conclusion: This study confirms findings from other national and international researches about the experience of cell phone phantom sensations and their relationship with the pattern of phone use and stress level. It also brings to light high levels of stress and problematic smartphone use among medical students during the internship. PMID- 30275620 TI - Addiction-like Behavior Associated with Mobile Phone Usage among Medical Students in Delhi. AB - Background: Mobile phone addiction is a type of technological addiction or nonsubstance addiction. The present study was conducted with the objectives of developing and validating a mobile phone addiction scale in medical students and to assess the burden and factors associated with mobile phone addiction-like behavior. Materials and Methods: A cross-sectional study was conducted among undergraduate medical students aged >=18 years studying in a medical college in New Delhi, India from December 2016 to May 2017. A pretested self-administered questionnaire was used for data collection. Mobile phone addiction was assessed using a self-designed 20-item Mobile Phone Addiction Scale (MPAS). Data were analyzed using IBM SPSS Version 17. Results: The study comprised of 233 (60.1%) male and 155 (39.9%) female medical students with a mean age of 20.48 years. MPAS had a high level of internal consistency (Cronbach's alpha 0.90). Bartlett's test of sphericity was statistically significant (P < 0.0001), indicating that the MPAS data were likely factorizable. A principal component analysis found strong loadings on items relating to four components: harmful use, intense desire, impaired control, and tolerance. A subsequent two-stage cluster analysis of all the 20-items of the MPAS classified 155 (39.9%) students with mobile phone addiction-like behavior that was lower in adolescent compared to older students, but there was no significant difference across gender. Conclusion: Mobile phone use with increasing adoption of smartphones promotes an addiction-like behavior that is evolving as a public health problem in a large proportion of Indian youth. PMID- 30275621 TI - Usage of Online Social Networking Sites among School Students of Siliguri, West Bengal, India. AB - Background and Objective: Social networking sites (SNSs) are online platforms that provide individuals with an opportunity to manage their personal relationship and remain updated with the world. The primary objective of the present research was to find the pattern of school students' SNS usage and its influence on their academic performance. Materials and Methods: The setting was an English medium school situated in the metropolitan city of Siliguri in West Bengal. A pretested and predesigned questionnaire was self-administered anonymously by 388 randomly selected students. The data were analyzed using appropriate statistics. Results: Three hundred thirty-eight (87.1%) students used SNS and spent an increased amount of time on these networks. Addiction was seen in 70.7% and was more common in the age group of 17 years and above. Conclusion: There is a need to educate students about the ways of using SNS and the perils associated with it, to help them understand that though very much in trend, they should be used cautiously. PMID- 30275622 TI - Internet Use Patterns, Internet Addiction, and Psychological Distress Among Engineering University Students: A Study from India. AB - Background: Internet addiction (IA) among university engineering students and its association with psychological distress can impact their educational progress, academic competence, and long-term career goals. Thus, there is a need to investigate the IA among engineering students. Objectives: This study was a first such attempt to explore internet use behaviors, IA, among a large group of engineering students from India, and its association with psychological distress primarily depressive symptoms. Methods: One thousand eighty six engineering students aged 18-21 years pursuing bachelors in engineering from the south Indian city of Mangalore participated in the study. The socio-educational and internet use behaviors data sheet was used to gather demographic information and patterns of internet use, Internet Addiction Test (IAT) was utilized to assess IA, and Self-Report Questionnaire (SRQ-20) assessed psychological distress primarily depressive symptoms. Results: Among the total N = 1086, 27.1% of engineering students met criterion for mild addictive internet use, 9.7% for moderate addictive internet use, and 0.4% for severe addiction to internet. IA was higher among engineering students who were male, staying in rented accommodations, accessed internet several times a day, spent more than 3 h per day on internet, and had psychological distress. Gender, duration of use, time spent per day, frequency of internet use, and psychological distress (depressive symptoms) predicted IA. Conclusions: A substantial proportion of engineering students have IA which can be detrimental for their educational progress in university studies and long-term career goals. Early identification and management of IA and psychological distress among engineering students is crucial. PMID- 30275624 TI - Lives without Roots: Institutionalized Homeless Women with Chronic Mental Illness. AB - The spiral phenomenon of homelessness and mental ill-health are major growing epidemic in both developed and developing countries. Viewing from a socio economic-political dimension, homelessness and mental ill-health cause detrimental effects on the individuals' lives as well as the nation-building process. The condition of women seems to be complex, as the gender perspectives are often described in terms of patriarchy and powerlessness. The bi directionality of mental illness and homelessness creates a vicious cycle, and many women seem to end up in shelter care homes. The scenario of homeless women with chronic mental illness reflects the lack of community-based rehabilitation efforts and gender-sensitive policy level initiatives. PMID- 30275623 TI - A Study of Magnitude and Psychological Correlates of Smartphone Use in Medical Students: A Pilot Study with A Novel Telemetric Approach. AB - Context: Smartphone use is being investigated as a potential behavioral addiction. Most of the studies opt for a subjective questionnaire-based method. This study evaluates the psychological correlates of excessive smartphone use. It uses a telemetric approach to quantitatively and objectively measure participants' smartphone use. Methodology: One hundred forty consenting undergraduate and postgraduate students using an Android smartphone at a tertiary care teaching hospital were recruited by serial sampling. They were pre-tested with the Smartphone Addiction Scale-Short Version, Big five inventory, Levenson's Locus of Control Scale, Ego Resiliency Scale, Perceived Stress Scale, and Materialism Values Scale. Participants' smartphones were installed with tracker apps, which kept track of total smartphone usage and time spent on individual apps, number of lock-unlock cycles, and total screen time. Data from tracker apps were recorded after 7 days. Results: About 36 % of participants fulfilled smartphone addiction criteria. Smartphone Addiction Scale score significantly predicted time spent on a smartphone in the 7-day period (beta = 0.234, t = 2.086, P = 0.039). Predictors for time spent on social networking sites were ego resiliency (beta = 0.256, t = 2.278, P = 0.008), conscientiousness (beta = 0.220, t = -2.307, P = 0.023), neuroticism (beta = -0.196, t = -2.037, P = 0.044), and openness (beta = -0.225, t = -2.349, P = 0.020). Time spent gaming was predicted by success domain of materialism (beta =0.265, t = 2.723, P = 0.007) and shopping by ego resiliency and happiness domain of materialism. Conclusions: Telemetric approach is a sound, objective method for evaluating smartphone use. Psychological factors predict overall smartphone usage as well as usage of individual apps. Smartphone Addiction Scale scores correlate with and predict overall smartphone usage. PMID- 30275625 TI - Low-frequency Repetitive Transcranial Magnetic Stimulation for Treatment of Tourette Syndrome: A Naturalistic Study with 3 Months of Follow-up. AB - The objective of this study is to report the effects of low-frequency repetitive transcranial magnetic stimulation (rTMS) in three patients with medication refractory Tourette syndrome (TS) and over 3-month follow-up. A review of literature on the use of rTMS for the treatment of TS is also presented. Three patients with severe, medication-refractory TS and comorbid obsessive-compulsive disorder (OCD) in two of them, received an open-label trial of rTMS at 1 Hz frequency for 4-week duration. The first two cases of TS-OCD showed, on average, around 57% improvement in Yale Global Tic Severity Scale (YGTSS) scores (65% and 50%) and 45% improvement in Yale-Brown Obsessive-compulsive Scale (Y-BOCS) scores; however, the third case of pure-TS showed marginal improvement of 10% only. The improvement in TS-OCD patients with rTMS treatment was maintained at the end of 3-month follow-up, with an average reduction of about 49% (58% and 40%) and 36% observed in YGTSS and Y-BOCS scores, respectively. The present study supports the use of low-frequency rTMS to improve tics and OCD symptoms in patients with severe, medication-refractory TS-OCD. Further, the beneficial effects of rTMS treatment were maintained substantially over 3-month follow-up period.

PMID- 30275631 TI - Internal, External, and Ecological Validity in Research Design, Conduct, and Evaluation. AB - Reliability and validity describe desirable psychometric characteristics of research instruments. The concept of validity is also applied to research studies and their findings. Internal validity examines whether the study design, conduct, and analysis answer the research questions without bias. External validity examines whether the study findings can be generalized to other contexts. Ecological validity examines, specifically, whether the study findings can be generalized to real-life settings; thus ecological validity is a subtype of external validity. These concepts are explained using examples so that readers may understand why the consideration of internal, external, and ecological validity is important for designing and conducting studies, and for understanding the merits of published research. PMID- 30275632 TI - Potential of Aqueous Two-Phase Systems for the Separation of Levodopa from Similar Biomolecules. AB - Background: Levodopa is a precursor of several neurotransmitters, such as dopamine, and is used in the treatment of the Parkinson's disease. In this work, an alternative strategy was studied to separate levodopa from similar biomolecules using aqueous two-phase systems (ATPS). Results: Ternary ATPS composed of polyethylene glycol (PEG) 400 or ionic liquids (ILs), citrate buffer (K3C6H5O7/C6H8O7) at pH 7.0 and water, and quaternary ATPS composed of PEG 400, K3C6H5O7/C6H8O7 at pH 7.0, water and the same ILs at 5 wt%, were studied. The respective liquid-liquid phase diagrams were determined at 298 K to appraise the mixture compositions required to form two-phase systems, followed by studies of the partition of levodopa and structurally similar biomolecules (dopamine, L phenylalanine, and L-tyrosine). Their partition coefficients and extraction efficiencies have been determined, and the selectivity of the ATPS to separate levodopa from the remaining biomolecules evaluated. Conclusion: The results obtained indicated that PEG-based ATPS were the most effective to separate levodopa from L-phenylalanine while the separation from the other biomolecules was better using IL-based ATPS, in particular those based on [P4444]Cl and [N4444]Cl, with extraction efficiencies of levodopa to the salt-rich phase ranging between 62.7 and 74.0%, and of the remaining biomolecules to polymer/IL rich phase up to 91.5%.

PMID- 30275634 TI - Incorporating a Cognitive Strategy Approach into an Outpatient Stroke Physiotherapy Programme: Case Report. AB - Purpose: Cognitive Orientation to daily Occupational Performance (CO-OP) has demonstrated an effect on skill performance, compared with the usual outpatient rehabilitation, in people living with stroke when implemented by occupational therapists. This study explored refining CO-OP for delivery by both occupational therapists and physiotherapists. Client Description: Two cases were recruited and treated using the CO-OP approach, which augments task-specific training with cognitive strategies and guided discovery. Intervention: Case 1 was a 79-year-old woman, 31 days after parietal stroke, and Case 2 was a 45-year-old man, 62 days after bilateral brain stem stroke. Case 1 withdrew from the study for medical reasons. Outcome measures applied were the Canadian Occupational Performance Measure, the Stroke Impact Scale (SIS), the Self-Efficacy Gauge, the Berg Balance Scale, the Box and Block Test, and the 2-minute walk test. Measures and Outcomes: After 10 sessions, Case 2 made gains in most measures, including a 22-point gain in the SIS mobility domain. Implications: The therapists reported that the combined delivery required additional communication with the patients but was feasible. Case 2 reported physical and mobility gains larger than the mean changes seen in past CO-OP research. Although these results cannot be generalized, findings suggest that the inter-professional application of CO-OP warrants further investigation. PMID- 30275635 TI - Impact of Course Configuration on 6-Minute Walk Test Performance of People with Lower Extremity Amputations. AB - Purpose: The configuration of the 6-minute walk test (6MWT) may influence the distance walked and comparability of results among subjects and across programmes. The purpose of this study was to evaluate the relative and absolute test-retest reliability of two 6MWT configurations and to evaluate the agreement between these two configurations in users of lower extremity prosthetics. Methods: A cross-sectional design was used to analyze data from 25 subjects completing in-patient prosthetic rehabilitation (mean age 63.12 [SD 13.77] y; 72% male). Two configurations of the 6MWT were examined, and relative and absolute test-retest reliabilities were calculated. Bland-Altman plots were constructed to evaluate agreement between configurations. Results: The relative test-retest reliability was excellent for both Configuration 1 and Configuration 2: ICC 0.97, 95% CI: 0.93, 0.98, and ICC 0.97, 95% CI: 0.94, 0.99, respectively. Comparable values for absolute test-retest reliability were also found. The Bland-Altman plot demonstrated a difference of +/-63.92 meters between configurations. Conclusions: The two 6MWT configurations had excellent relative and absolute test retest reliability, but the results from each configuration do not agree sufficiently to make them interchangeable or directly comparable. This highlights the importance of explicitly indicating the test configuration for the 6MWT when reporting results. PMID- 30275636 TI - A Pre-Operative Exercise Intervention Can Be Safely Delivered to People with Femoroacetabular Impingement and Improve Clinical and Biomechanical Outcomes. AB - Purpose: This study aimed to investigate the effects of a pre-hip arthroscopy exercise intervention on hip strength, pain, and function in individuals with femoroacetabular impingement (FAI). Methods: A total of 20 individuals with FAI completed a 10-week, partially supervised exercise programme; this included three phases of increasing resistance and functionality, consisting of four to six exercises per phase. Hip strength in all six directions; hip pain; function, as measured by the Hip disability and Osteoarthritis Outcome Score (HOOS); and objective physical function, as measured by the Timed Stair Climb test, were determined before and after the intervention. Results: Maximum isometric hip strength significantly increased in abduction (p=0.008), adduction (p=0.021), and internal rotation (p=0.006) at follow-up. Increases in flexion, extension, and external rotation strength did not reach statistical significance. Self-reported HOOS pain (p<0.01) and activities of daily living sub-scale scores (p<0.01) significantly improved at follow-up. Timed Stair Climb times (p<0.001) also significantly decreased at follow-up. Conclusion: A 10-week exercise programme can be safely completed by adults with FAI before surgery, and statistically significant changes in strength, function, and self-reported clinical outcomes can be achieved. PMID- 30275637 TI - Gluteus Medius and Minimus Muscle Structure, Strength, and Function in Healthy Adults: Brief Report. AB - Purpose: This article describes gluteus medius and minimus muscle thickness and hip abductor strength and function in healthy adults and explores the relationships between muscle thickness and function. Methods: Gluteus medius and minimus muscle thickness (B-mode ultrasound), isometric hip abductor strength (Biodex dynamometer), and lower extremity function (timed Trendelenburg test, Five-Times-Sit-to-Stand Test [FTSST], and lateral step-down test) were measured in healthy adults using a cross-sectional study design. Results: A total of 22 subjects were included: 10 men and 12 women, mean age 25.2 (SD 3.1) years, mean BMI 22.9 (SD 3.5) kilograms per metre squared. Muscle thickness of the gluteals was a mean 3.88 (SD 0.13) centimetres, and mean hip abductor peak torque was 111 (SD 43) newton-metres. FTSST mean time was 5.3 (SD 0.2) seconds, and median scores were 2.0 points for lateral step-down and 90 seconds for timed Trendelenburg. No significant relationships were found between gluteal muscle thickness and functional tests (rs=-0.28 to 0.37, ps=0.09-0.80) or strength (r= 0.24, p=0.28). Conclusion: Although hip abductors are key pelvic stabilizers for functional movements, gluteal muscle thickness was not associated with strength or function. This may be a result of agonist muscle activity, leading to an inability to isolate the gluteals, and to the ceiling effects of the functional tests. PMID- 30275638 TI - Balance Assessment Practices of Saskatchewan Physiotherapists: A Brief Report of Survey Findings. AB - Purpose: This study was conducted to determine the balance assessment practices of physiotherapists in Saskatchewan. Methods: Practising physiotherapists who assess and treat adults with balance and mobility impairments were eligible to participate in this cross-sectional, online survey. The questions investigated the use of balance assessment measures, the balance components assessed, and practice area. Results: Of the 72 respondents, most reported regularly assessing five or more of the nine balance components listed. Movement observation was the most commonly reported measure used, followed by the Berg Balance Scale, single leg stance test, and tandem standing/walking. Conclusions: Most physiotherapists in Saskatchewan use a variety of tools to assess balance. Gaps in practices related to fall prevention were noted in the mismatch between the tools used and the components reportedly assessed. PMID- 30275639 TI - To Be or Not to Be a Cardiorespiratory Physiotherapist: Factors That Influence Career Choice in a Sample of Canadian Physiotherapists. AB - Purpose: This study explored the factors that influence choosing or not choosing a career in cardiorespiratory physiotherapy (CRP) from the perspective of a group of currently practising, experienced physiotherapists in Canada. Methods: A modified Dillman approach was used to distribute a cross-sectional, self administered, online questionnaire to all eligible members of the cardiorespiratory and orthopaedic divisions of the Canadian Physiotherapy Association. A total of 438 participants-21 CRP and 417 non-CRP therapists completed the survey. The survey response rate was 9.4%. Results: A narrow scope of practice (61.9%) and a lack of interest in CRP subject matter (50.1%) were the most influential factors deterring the respondents from making CRP their career choice. Interest in CRP (81.0%), mentorship (76.2%), access to physical resources (76.2%), and inter-professional practice (71.4%) were the most influential factors in pursuing a career in CRP. Conclusion: Increasing the awareness of the scope of practice for CRP, exposure to positive mentors, and rich practice settings are key factors in promoting physiotherapists' specialisation in CRP. PMID- 30275640 TI - Exploring Record Keeping, Clinical Reasoning, and Practice Context: Peer Assessment Findings from the Perspective of Situational Competence. AB - Purpose: The College of Physiotherapists of Ontario developed its peer practice assessment (PA) process on the basis of the statutory requirements for quality assurance. We previously reported outcomes from physiotherapists who had two PAs. The aims of the current research were to identify areas of sub-optimal performance on the assessments and explore any associations with the physiotherapists' practice context. Methods: We examined scores from the PAs of all physiotherapists who had two unrelated PAs between 2004 and 2012 (n=117), and we examined assessment reports for those who had specific patterns of sub-optimal outcomes (n=22). We conducted qualitative content analysis on the assessment reports to identify areas deemed to need improvement and the contexts in which the physiotherapists practised. Comparisons of proportions were carried out using Fisher's exact test. Results: The most common area of sub-optimal scores was record keeping, followed by clinical reasoning as assessed by means of chart stimulated recall. Record-keeping deficits were related to either clinical care or administrative requirements (e.g., documenting patient consent in the manner required by law). At the second PA, record-keeping deficits were predominantly administrative. Physiotherapists with sub-optimal outcomes disproportionately worked in private practice contexts (p=0.026). Conclusions: Ontario physiotherapists generally maintain high-quality practice. Regulatory bodies may consider developing support strategies for meeting professional standards that take practice context into account. PMID- 30275643 TI - What Does Cochrane Say About ... Vestibular Rehabilitation? PMID- 30275641 TI - Return to Meaningful Activities After a Multi-Modal Rehabilitation Programme among Individuals Who Experience Persistent Dizziness and Debility Longer Than 9 Months after Sustaining a Concussion: A Case Series. AB - Purpose: The authors explored changes in outcome measures and return to meaningful life activities in six individuals who participated in a home-based multi-modal rehabilitation programme to address persistent dizziness and debility that had continued for more than 9 months since a documented concussion. Methods: In a case series using a repeated-measures design, changes from pre- to post treatment assessments were assessed after a 6-month intervention. The outcome measures used were the Rivermead Post-Concussion Symptoms Questionnaire's subsidiary scales (RPQ-3, RPQ-13), Dizziness Handicap Inventory (DHI), Activities specific Balance Confidence Scale, Functional Gait Assessment, return to work or study, and return to activity. Results: Six months after the multi-modal rehabilitation programme, statistically significant differences were found on the RPQ-3 (p=0.026), RPQ-13 (p=0.037), and DHI (p=0.033). In addition, four participants had returned to their previous work, and all six participants had been able to return to physical activity. Conclusion: A supervised home programme, provided in the context of a multi-modal rehabilitation programme, has the potential to improve outcomes even when rehabilitative services are delayed and persistent concussion-related symptoms continue for a significant amount of time after the onset of a concussion. PMID- 30275642 TI - Physical Activity and Sedentary Behaviour of Master of Physical Therapy Students: An Exploratory Study of Facilitators and Barriers. AB - Purpose: A full 85% of Canadians fail to meet physical activity (PA) guidelines, and 69% report being sedentary. Physical therapists are uniquely positioned to promote an active lifestyle; thus, we explored the PA and sedentary behaviour (SB) of Master of Physical Therapy (MPT) students as well as the associated facilitators and barriers. Methods: We used a mixed-methods approach, accelerometry and photovoice (a focus group discussion in which participants discussed self-selected photographs). Accelerometer data were used to quantify PA (light, moderate, and vigorous) and SB. Thematic analysis of the focus group discussion was informed by the socio-ecological model. Results: A total of 26% of participants met national PA guidelines, and mean daily sedentary time for participants was 670.7 (SD 34.4) minutes. Photovoice analysis revealed four main themes related to the facilitators of and barriers to PA and SB: (1) priorities and life balance, (2) commitment and accountability, (3) environment, and (4) MPT programming. Conclusions: A full 74% of participants did not meet the recommended PA guidelines; this is concerning given their immanent roles as health care professionals. Physical therapists are well prepared to prescribe PA to clients. Not only do MPT students need competencies in prescribing PA and exercise, but they may also need to be supported in meeting PA guidelines themselves and limiting SB throughout their studies.

PMID- 30275645 TI - Self-Management Strategies for Malignant Lymphedema: A Case Report with 1-Year and 4-Year Follow-Up Data. AB - Purpose: Malignant lymphedema is an accumulation of interstitial fluid caused by tumour infiltration or compression of lymphatic vessels. Our objective is to describe self-management strategies for malignant lymphedema using a case report. Client Description: A 50-year-old woman with advanced breast cancer was referred to our centre with a 3-month history of unexplained left-arm edema, subsequently diagnosed as malignant lymphedema caused by tumour compression of the axillary lymph nodes. Intervention: She undertook a physiotherapist-guided, modified lymphedema treatment programme, with self-management interventions including self bandaging and exercise. Limb volumes and leisure exercise levels were measured over a 1-year period. Data were collected from her follow-up visit 4 years post diagnosis of lymphedema. Measures and Outcome: Within the first month, the patient's excess limb volume reduced from 26.8% to 5.9% and, 1 year later, remained stable at 3%. Over time, her exercise levels increased (1-year follow up: 33.5 MET-hours per week). At 4 years, her excess limb volume was 9.7%, and exercise levels were at 36 MET-hours per week. Implications: A woman with moderate malignant arm lymphedema caused by advanced breast cancer successfully adhered to a guided self-management programme and benefited from reduced swelling and improved self-reported physical function in the long term. This case provides oncology health professionals with knowledge about self-management options for malignant lymphedema. PMID- 30275646 TI - Neuropathic Pain after Shoulder Arthroplasty: Prevalence, Impact on Physical and Mental Function, and Demographic Determinants. AB - Purpose: The objectives of this survey study were to provide an estimate of the prevalence of neuropathic pain (NP) and to explore the cross-sectional and longitudinal group differences postoperatively. Method: A cohort of consecutive patients who had undergone total shoulder arthroplasty (TSA), reverse shoulder arthroplasty (RSA), or humeral head replacement (HHR) were surveyed within an average of 3.8 years after surgery. Questionnaires completed at the time of the survey were the Self-Administered Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) pain scale, the visual analogue scale (VAS) for pain, the Western Ontario Osteoarthritis of the Shoulder (WOOS) index, the Patient Health Questionnaire-9 (PHQ-9), and a satisfaction questionnaire. Results: Of the 141 candidates who were invited to participate in the study, 115 patients participated (85 TSA, 21 HHR, and 9 RSA), for an 82% response rate. Five patients (4%) met the criteria for NP, of whom one had a loosening of the prosthesis and required further surgery. Having NP was associated with greater pain (VAS; p=0.001), greater depression (PHQ-9; p=0.001), more disability (WOOS; p=0.030), and less satisfaction with the surgery (p=0.014). There was no relationship between the presence of NP and patients' age, sex, preoperative pain, range of motion results, or WOOS scores (p>0.05). Conclusions: Persistent pain of neuropathic origin is not common after shoulder arthroplasty, but it is a significant contributor to poor mental and physical well-being and thus warrants further research. PMID- 30275647 TI - Gait Training after Stroke on a Self-Paced Treadmill with and without Virtual Environment Scenarios: A Proof-of-Principle Study. AB - Purpose: The purpose of this proof-of-principle study was to show that virtual reality (VR) technology could be coupled with a self-paced treadmill to further improve walking competency in individuals with chronic stroke. Method: A 62-year old man with a chronic right hemispheric stroke participated in a treadmill walking programme involving first a control (CTL) protocol, then VR training. In CTL training, he walked without time constraints while viewing still pictures and reacting to treadmill movements similar to those that he would have experienced later in VR training. In VR training, he experienced treadmill movements programmed to simulate changes encountered in five virtual environments rear projected onto a large screen. Training difficulty in nine sessions over 3 weeks was increased by varying the time constraints, terrain surface changes, and obstacles to avoid. Effects on walking competency were assessed using clinical measures (5 m walk test, 6 min walk test, Berg Balance Scale, Activities-specific Balance Confidence scale) and questionnaires (Assessment of Life Habits Scale and personal appraisal). Results: CTL and VR training resulted in a similar progression through the training sessions of total time walked on the treadmill. The VR training led to an additional increase in speed as measured by walking 5 metres as fast as possible and distance walked in 6 minutes, as well as improved balance self-efficacy and anticipatory locomotor adjustments. As reported by the participant, these improved outcomes transferred to real-life situations. Conclusions: Despite the limited potential for functional recovery from chronic stroke, an individual can achieve improvements in mobility and self-efficacy after participating in VR-coupled treadmill training, compared with treadmill training with the same intensity and surface perturbations but without VR immersion. A larger scale, randomized controlled trial is warranted to determine the efficacy of VR-coupled treadmill training for mobility intervention post stroke. PMID- 30275648 TI - Gross Motor Outcomes of Children Born Prematurely in Northern Ontario and Followed by a Neonatal Follow-Up Programme. AB - Purpose: The developing brain of a premature infant is vulnerable to injury. As a result, the long-term consequences of a premature birth include motor deficits, cognitive and behavioural problems. It is crucial to identify motor dysfunction during the preschool period because it interferes with a child's ability to explore the world. The goals of this study were to (1) provide preliminary data on the gross motor outcomes of children born prematurely and (2) determine the proportion and characteristics of the children who had maintained delays over the course of follow-up. Method: A retrospective chart review was conducted on all infants monitored by a neonatal follow-up programme. Each child was assessed by a single physiotherapist from birth until age 2 years. Of the 107 cases identified, 97 individuals were retained for analysis; they had a mean gestational age of 31.1 (SD 2.9) weeks and a mean birth weight of 1.66 (SD 0.53) kilograms. Results: The majority of children assessed were found to have gross motor outcomes in the average range. Children with scores below the average range were most often born very preterm (VPT) or moderately preterm (MPT), with very low or low birth weight, respectively. A total of 17 participants were referred to physiotherapy to address the gross motor delays identified in the follow-up programme; 14 of these 17 had previously been identified as delayed and were being monitored. Late preterm (LPT) children (n=6) were most often referred, followed by those born extremely preterm (EPT) and VPT (n=4). In total, 56 children were identified as delayed at one assessment point but were found to be within normal limits by the end of the follow-up period. Conclusion: It is important to periodically monitor premature children. A longitudinal, population-based study is also needed to provide more data on the predictors and long-term motor outcomes of MPT and LPT children. PMID- 30275649 TI - Let's Talk about the Talk: Exploring the Experience of Discussing Student Performance at the Mid- and Final Points of the Clinical Internship. AB - Purpose: The purpose of this study was to explore the experiences of physiotherapy students and clinical instructors (CIs) when discussing student clinical performance at the mid- and final points of clinical internships. The objectives were to identify why performance assessment discussions are valuable, explore the role of each participant throughout the discussion, identify the challenges associated with these discussions, and explore the effect of the standardized assessment tool on the discussion. Methods: This study used a qualitative descriptive design, consisting of student and CI focus groups in the Greater Toronto Area from January to June 2016. Results: All participants (N=29) recognized the importance of having face-to-face performance assessment discussions in a quiet and private space. Students and CIs agreed that the Canadian Physiotherapy Assessment of Clinical Performance helped to structure and focus the discussions. Valuable discussions occurred when students were open minded and self-reflected on their performance and when CIs were honest and used their expertise to guide learning. Other key features included mutual preparedness, two-way feedback that was constructive and tangible, and a goal setting process. Students described the emotional component of these discussions as being challenging, and CIs found it difficult when a student took a more passive role in the discussion. Conclusions: Our findings indicate that valuable discussions can provide meaningful feedback, strengthen the student-CI relationship, and engage the learner in an ongoing and cumulative learning process that contributes to professional development. PMID- 30275650 TI - Physiotherapists' and Physiotherapy Students' Perspectives on the Use of Mobile or Wearable Technology in Their Practice. AB - Purpose: Although extensive research has been carried out on the determinants of mobile or wearable health care technology (mHealth), as well as on its acceptance by patients and other health care providers, very little research has been done on physiotherapists' perspectives on the use of mHealth in their current or future practice. The aims of this study were to (1) explore the attitudes of physiotherapists toward mHealth using a modified technology acceptance model questionnaire, (2) understand the applications and delivery paradigms that are most desirable, and (3) assess the content validity of the questionnaire. Method: The questionnaire was administered online. Participants (n=76) were recruited using snowball and convenience sampling. Data were analyzed using factor analysis and partial least-squares path modelling. Results: Results indicate that perceived usefulness and perceived ease of use were related to early adoptive behaviour among participants. We found no evidence that age, gender, experience, or practice setting influenced early adoptive behaviour. Participants demonstrated favourable attitudes toward mHealth tools in clinical practice. Conclusions: This article provides initial insights into factors that are likely to be significant determinants of adoption of mHealth among physiotherapists. Further work, including qualitative research, will help to identify personal and institutional factors that will improve the acceptance of mHealth. PMID- 30275651 TI - Simulation Experiences in Canadian Physiotherapy Programmes: A Description of Current Practices. AB - Purpose: Although health care professional education programmes around the world are increasingly using sophisticated simulation technology, the scope of simulation use in Canadian physiotherapy programmes is currently undefined. The current study explores the definitions of simulation, its current use, and the perceived benefits and barriers in Canadian entry-to-practice physiotherapy programmes. Method: Using a qualitative, descriptive study approach, we contacted Canadian physiotherapy programmes to identify faculty members with simulation experience. Using a semi-structured interview format, we asked participants to discuss their perspectives of simulation in their physiotherapy programmes. Interviews were audio recorded, transcribed, and analyzed for themes. Results: Of 13 eligible Canadian physiotherapy programmes, participants from 8 were interviewed. The interviews revealed three major themes: (1) variability in the definition of fidelity in simulation, (2) variability in simulation use, and (3) the benefits of and barriers to the use of simulation. Conclusions: Variability in the definition of fidelity in simulation among Canadian physiotherapy programmes is consistent with the current literature, highlighting a spectrum of complexity from low fidelity to high fidelity. Physiotherapy programmes are using a variety of simulations, with the aim of creating a bridge from theoretical knowledge to clinical practice. This study describes the starting point for characterizing simulation implementation in Canadian physiotherapy programmes and reflects the diversity that exists across the country. PMID- 30275652 TI - Variation in the Geographic Distribution of Physiotherapy Student Clinical Placements in Rural Saskatchewan. AB - Purpose: Rural and remote Saskatchewan has a shortage of physiotherapists. Positive student experiences in rural and remote communities may influence whether graduates choose to work in these settings. The intention of the first full-time, 4-week clinical placement (CP) in the Master of Physical Therapy programme at the University of Saskatchewan is to provide clinical experiences in rural settings outside Saskatoon and Regina. This study examines the geographic distribution of and yearly variation in these CPs to determine whether this stated intent is being realized. Method: We analyzed the locations of physiotherapy student CPs from 2008 to 2016 using geospatial mapping. Results: Spatial patterning using mapping identified variability in the number of rural placements in geographical regions in Saskatchewan over a 9-year period. An average of 75% of CP experiences occurred in rural locations outside the two major cities in Saskatchewan between 2008 and 2016 (ranging from 58% in 2015 to 84% in 2009). Conclusions: The goal of providing all University of Saskatchewan physiotherapy students with a rural experience for their first CP is not being met. Securing more CPs in rural settings may have a positive impact on recruitment of physiotherapists to these communities. PMID- 30275653 TI - Facilitators of and Barriers to Providing Access to Community-Based Exercise Programmes for Adults with Post-Stroke Aphasia from the Perspective of Programme Representatives. AB - Purpose: Individuals with post-stroke aphasia (PSA) engage in inadequate levels of physical activity (PA), hindering physical and psychosocial recovery. The purpose of this study was to identify the extent to which community-based exercise programmes (CBEPs) in the Greater Toronto Area (GTA) are accessible to adults living with PSA and the characteristics of such programmes from the perspective of CBEP representatives. Methods: A cross-sectional, Web-based survey was administered to representatives of CBEPs open to adults post-stroke in the GTA to identify the CBEPs' relevant characteristics and perceived facilitators of and barriers to accessibility. Results: A total of 17 eligible CBEP representatives completed the survey, for a response rate of 32%. The most commonly used exercise instructors were personal trainers (8; 47%). Of the 17 eligible CBEP representatives, 10 (59%) identified a lack of qualified personnel as the main barrier to providing access to adults with PSA. Verbal strategies were among the most commonly used methods of communication with adults with PSA (16; 94%), and written material was the least used (5; 29%). Conclusion: Understanding the common facilitators of and barriers to providing adults with PSA access to CBEPs will assist programme developers to improve the accessibility of CBEPs and facilitate PA in this population.

PMID- 30275654 TI - "A Learned Soul to Guide Me": The Voices of Those Living with Kidney Disease Inform Physical Activity Programming. AB - Purpose: The purpose of this study was to (a) confirm the barriers to and facilitators of physical activity (PA) among persons living with chronic kidney disease (CKD) in Ontario and (b) inform the design of a Kidney Foundation of Canada Active Living for Life programme for persons living with CKD. Method: Adults living with CKD in Ontario were invited to participate in a cross sectional survey investigating opinions about and needs for PA programming. The 32-item survey contained four sections: programme delivery preferences, current PA behaviour, determinants of PA, and demographics. Data were summarized using descriptive statistics and thematic coding. Results: A total of 63 respondents participated. They had a mean age of 56 (SD 16) years, were 50% female, and were 54% Caucasian; 66% had some post-secondary education. The most commonly reported total weekly PA was 90 minutes (range 0-1,050 minutes). Most respondents (84%) did not regularly perform strength training, and 73% reported having an interest in participating in a PA programme. Conclusion: Individuals living with CKD require resources to support and maintain a physically active lifestyle. We identified a diversity of needs, and they require a flexible and individualized inter-professional strategy that is responsive to the episodic changes in health status common in this population. PMID- 30275656 TI - A quasi-score statistic for homogeneity testing against covariate-varying heterogeneity. AB - In statistical modeling, it is often of interest to evaluate non-negative quantities that capture heterogeneity in the population such as variances, mixing proportions and dispersion parameters. In instances of covariate-dependent heterogeneity, the implied homogeneity hypotheses are nonstandard and existing inferential techniques are not applicable. In this paper, we develop a quasi score test statistic to evaluate homogeneity against heterogeneity that varies with a covariate profile through a regression model. We establish the limiting null distribution of the proposed test as a functional of mixtures of chi-square processes. The methodology does not require the full distribution of the data to be entirely specified. Instead, a general estimating function for a finite dimensional component of the model that is of interest is assumed but other characteristics of the population are left completely unspecified. We apply the methodology to evaluate the excess zero proportion in zero-inflated models for count data. Our numerical simulations show that the proposed test can greatly improve efficiency over tests of homogeneity that neglect covariate information under the alternative hypothesis. An empirical application to dental caries indices demonstrates the importance and practical utility of the methodology in detecting excess zeros in the data.

PMID- 30275671 TI - Positive Parenting Moderates the Association between Temperament and Self Regulation in Low-Income Toddlers. AB - Self-regulation develops rapidly during the toddler years and underlies many important developmental outcomes, including social-emotional competence and academic achievement. It is important to understand factors that contribute to early self-regulation skills among children at risk for adjustment difficulties in these domains, such as children growing up in poverty. The current study examined mother-reported child temperament (negative affect, effortful control) and observed maternal parenting (during a mother-child free play) as contributing factors to toddlers' observed self-regulation during delay of gratification tasks at 27 months (snack delay) and 33 months (gift delay). Participants were 198 toddlers (M age = 27 months; 53% boys; 48% non-Hispanic white) and their mothers from low-income families. Mothers' negative parenting characterized by negative affect, hostility, and negative control was associated with poorer self regulation contemporaneously. Toddlers' lower negative affect and higher effortful control predicted better self-regulation at 33 months, but positive parenting characterized by positive affect and sensitivity moderated these associations at both time points. Specifically, we found a buffering effect of high positive parenting among toddlers with a temperamental risk and a deleterious effect of low positive parenting despite toddlers' temperamental strength. Results highlight the importance of positive parenting for fostering the development of self-regulation among toddlers growing up with poverty-related and child-level risks. PMID- 30275672 TI - Readmission After Elective Ileostomy in Colorectal Surgery Is Predictable. AB - Background and Objectives: Patients who undergo colorectal surgery have high postoperative morbidity, with ileostomates being the most disadvantaged. Recent studies assessing readmission risk factors do not provide a specific prediction model and, if so, do not focus on patients who have had colorectal surgery; thus, the results of these studies have limited applicability to our specialized practice. We wanted to develop a prediction model for readmission within 30 days of discharge after ileostomy creation. Methods: Patients who underwent elective ileostomy creation from 2013 to 2016 at the University of Florida were included in this retrospective study. Factors significantly associated with readmission within 30 days after discharge were identified by comparing a cohort that was readmitted within 30 days with one that was not. A practical, predictive model that stratified a patient's risk of readmission after the index procedure was developed. Results: A total of 86 iliostomates were included; of those, 22 (26%) were readmitted within 30 days. Factors significantly associated with readmission included preoperative steroid use, history of diabetes, history of depression, lack of a hospital social worker or postoperative ostomy education, and the presence of complications after the index procedure. A model predicting readmission within 30 days of discharge that comprised the first 4 factors was developed, with a sensitivity of 73% and a specificity of 77%. Conclusion: Prediction of readmission in patients who undergo ileostomy creation is possible, suggesting interventions addressing predictive factors that may help decrease the readmission rate. Prospective validation of the model in a larger cohort is needed. PMID- 30275673 TI - Trends of Opportunistic Salpingectomy. AB - Background and Objectives: This study analyzed the trends of opportunistic salpingectomy (OS) accompanied by hysterectomy in a 9-year follow-up period at a single institute. Methods: This retrospective cohort study included 1184 women at Hualien Tzu Chi Hospital from 2007 to 2015 who underwent hysterectomy performed with or without OS. Parameters including patient age, operating time, surgical approach, length of hospital stay, and perioperative complications were evaluated. Results: There was an increase in the number of hysterectomies with OS (from 8% to 80%; P < .001) over the study period. Minimal additional operating time was necessary for hysterectomy with OS (3.7 and 3.6 minutes in open and laparoscopic surgery, respectively). No significant differences were observed in the risks of hospital readmission or blood transfusions between women who underwent hysterectomy with OS performed with the open approach and those who underwent the procedure using the laparoscopic approach. From 2007 to 2015, the proportion of open hysterectomies decreased from 56% to 6%. Conclusion: The results of this 9-year follow-up study revealed that, as a cancer prevention method, OS seems to be feasible and safe, requires minimal extra time, and does not increase the morbidity or long-term sequelae. PMID- 30275674 TI - Standardised Sleeve Gastrectomy Without Reinforcement. AB - Background and Objectives: Laparoscopic sleeve gastrectomy (LSG) has some unique complications, the most concerning of which is sleeve leak. Staple line reinforcement (SLR) has been suggested as a means of decreasing the risk of sleeve leak, but it increases the cost. However, there is little in the literature regarding the effect of standardized operative technique in reducing the complications and improving the outcomes in LSG. We sought to demonstrate that standardization of the operative procedure and perioperative care is the key to an excellent 30-day outcome and that SLR is not necessary to ensure a negligible staple line leak and bleeding rate. Methods: A prospectively maintained database was analyzed to identify 303 consecutive patients undergoing LSG between July 2010 and November 2017. Data on patient demographics, length of hospital stay, conversion to open surgery, perioperative complications, and mortality were analyzed. Standardized operative technique and postoperative protocol were followed in all cases. SLR was not used in any case. Results: Among 303 cases, there were 15 complications (5%), 5 (1.7%) of which were severe (Clavien-Dindo grade >=3a). There were no conversions to open procedure, no staple line leaks, and no inpatient deaths in the cohort. No patient was readmitted with an early stricture. Conclusions: The use of a standardized operative and postoperative protocol led to an excellent early outcome in our LSG cases. Standardization may act to obviate the need for routine SLR techniques which are associated with a significant financial cost to both patient and hospital. PMID- 30275675 TI - Robotic Neck Surgery in the Pediatric Population. AB - Introduction: Thyroid, parathyroid, and thymus surgeries are traditionally performed via a cervical approach. However, robot-assisted procedures can provide a safe alternative for neck surgeries. We report our experiences with robotic transaxillary and retroauricular approaches in pediatric patients. Case Presentation: We conducted a retrospective review of pediatric patients who underwent robot-assisted neck surgery by a single surgeon between April 2010 and May 2017. Patient demographics and surgical outcomes including operative time, incidence of complications, and length of hospital stay were evaluated. Management and Outcomes: Nine surgeries in 7 female patients were reviewed (mean age, 16.0 +/- 1.58 years; mean body mass index, 22.5 +/- 0.75). Two thyroid lobectomies, 2 complete thyroidectomies, 1 subtotal thyroidectomy, 1 thyroid lobectomy with thymectomy, 2 subtotal parathyroidectomies with thymectomy, and 1 dermoid cyst excision were performed. Two surgeries with the retroauricular approach had a mean surgical time of 142.0 +/- 6.13 minutes. Seven surgeries with the transaxillary approach had a mean surgical time of 146.1 +/- 21.01 minutes. There were no reported conversions, permanent vocal cord paralysis, permanent hypoparathyroidism, hematoma, or seroma. There was 1 case (11%) of temporary shoulder hypoesthesia and 2 cases of temporary vocal cord paresis (22%). Discussion: This series on robot-assisted neck surgeries in children describes procedures performed with robotic transaxillary and retroauricular approaches. In the hands of a high-volume surgeon the techniques are feasible and safe options for operations in the neck in a select group of pediatric patients. PMID- 30275676 TI - Transoral Endoscopic Thyroidectomy: A Systematic Review of the Practice So Far. AB - Background and Objectives: Thyroid disease largely affects young females, but the incidence is also increasing among males. In an effort to avoid the scarring of the neck that is synonymous with conventional thyroidectomy, endoscopic techniques have been developed over the years. The transoral endoscopic approach is the latest of these innovations that promises a scarless surgical outcome. This review evaluates whether this technique is safe and feasible in live patients and outlines the outcomes in published literature so far. Database: PubMed, Medline, BioMed Central, Cochrane Library, OVID and Web of Science were systematically searched by using a Medical Subject Heading (MeSH)-optimized search strategy. The selection of papers followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines after setting strict inclusion and exclusion criteria. Sixteen studies were included in the final analysis. Discussion: This systematic review presents cases of 785 patients. Surgeons in 15 of the studies used a completely vestibular approach, whereas those in the remaining 2 used the floor of the mouth for primary access. Conversion to open surgery took place in 1.3%. In total, 4.3% of patients experienced transient laryngeal nerve palsy, whereas 0.1% had permanent recurrent incidences of the condition. Transient hypocalcemia occurred in 7.4% of cases, with no recorded permanent cases. Carbon dioxide embolism occurred in 0.6% of cases, and another 0.6% had a deep-seated neck infection. The complication rates within the review were deemed acceptable and the overall technique feasible. A prospective randomized controlled trial was proposed to compare this technique with conventional thyroidectomy. PMID- 30275677 TI - Comparison of variations in cornea after one-handed and two-handed coaxial phacoemulsification. AB - Purpose: To compare corneal variations in patients undergoing one-handed and two handed coaxial phacoemulsification. Setting: Eye Institute, Affiliated Hospital of Nantong University, Nantong, China. Design: Prospective consecutive nonrandomized comparative cohort study. Methods: Patients with cataracts were subject to one-handed (one-handed group) or two-handed coaxial phacoemulsification (two-handed group). Intraoperative phaco parameters and postoperative outcomes, such as visual acuity, surgically induced astigmatism (SIA), corneal volume, central corneal thickness, and corneal endothelial cell counts/size were compared. Results: No significant differences in the intraoperative phaco parameters were noted between the 2 groups. At postoperative week 1, visual outcomes were significantly improved in the one-handed compared with the two-handed group (all P<0.05). Corneal volume, central corneal thickness, and average cell size were significantly decreased in the one-handed group compared with two-handed group (all P<0.05), but the aforementioned differences were ameliorated at 1 month and 3 months postoperatively. Endothelial cell loss was significantly decreased in the one-handed group compared with the two-handed group at any follow-up point (all P<0.05). No significant differences in SIA on the anterior surface were noted between the 2 groups. SIA on the posterior surface was significantly decreased in the one-handed group compared with the two-handed group at 1 week postoperatively (P=0.043) but not at 1 month and 3 months postoperatively. Conclusion: One-handed phacoemulsification has the advantages of less trauma to the cornea and better early visual outcomes compared with the two-handed technique. PMID- 30275678 TI - 8K ultra-high-definition microscopic camera for ophthalmic surgery. AB - Background: We have developed a new compact lightweight 8K ultra-high-definition (UHD; 7,680*4,320 pixels) camera and started medical application with an ophthalmic surgical microscope which is interchangeable with the conventional high-definition (1,920*1,080 pixels)/4K UHD (3,840*2,160 pixels) microscopic camera. Methods: We did a feasibility study to apply our 8K UHD microscope in cataract surgery, glaucoma surgery and vitreous surgery using pig cadaver eyes. The 8K UHD microscope comprises a surgical microscope, a camera adaptor with relay lenses, an 8K UHD camera and an 8K UHD LCD to share the 8K UHD images with all surgical staff in real time. Results: In ophthalmic surgeries, higher resolution images than conventional microscopic cameras were obtained with 8K UHD LCD equivalent to the observation through the microscopic eye pieces. Conclusion: Based on the results of this feasibility study, clinical trials on human ophthalmic surgery using the new 8K UHD microscopic camera should be conducted in the near future. PMID- 30275679 TI - The safety and efficacy of phaco-sleeve irrigation-assisted hydrodissection during femtosecond laser-assisted cataract surgery. AB - Femtosecond laser-assisted cataract surgery (FLACS) changes the intraoperative environment due to the generation of intracapsular gas that induces a high intracapsular volume. Manual hydrodissection (mH) may induce high intracapsular pressure (ICP) and additional intracapsular volume, thereby leading to capsular block syndrome (CBS). Since the phaco-sleeve irrigation-assisted hydrodissection (iH) technique is used to initially groove and split the lens and remove the intracapsular gas, this can reduce the intracapsular volume while bypassing the intracapsular lens prior to the hydrodissection. As iH uses the phaco tip to intentionally vacuum the intraocular fluid for use in inducing the irrigation jet from the sleeve side holes, the ICP cannot surpass the set irrigation pressure, thereby avoiding CBS. Using this technique, we performed FLACS without CBS in 310 cataract eyes. Our findings suggest that the iH technique may be beneficial for patients by preventing CBS during FLACS. PMID- 30275680 TI - Ocular hypotensive effects of prostaglandin analogs in Japanese patients with normal-tension glaucoma: a literature review. AB - Purpose: This paper aimed to evaluate the intraocular pressure (IOP)-lowering effects of prostaglandin analogs (PGAs) in Japanese patients with normal-tension glaucoma (NTG) by reviewing the current literature. Methods: In February 2018, database searches were performed in PubMed, Embase, ProQuest, and the Japanese databases JAPICDOC and JMEDPlus. Studies were sorted into two categories: Category 1 consisted of studies of patients with NTG who reported reduced IOP values and Category 2 consisted of studies of patients with NTG who had IOP values at predosing and a final evaluation point. Search terms included ([unoprostone or latanoprost or travoprost or bimatoprost or tafluprost] and [glaucoma] and [Japan or Japanese]). The weighted ocular hypotensive efficacy was calculated. A scatter plot analysis was performed and a regression equation was calculated for each medication. The fitting of each regression equation was evaluated by the least squares method. Results: Eleven articles were eligible for Category 1 and 25 articles for Category 2. In the rank order of IOP-lowering efficacy of PGAs, bimatoprost was the strongest and latanoprost the weakest. Travoprost and tafluprost had almost the same level of ocular hypotensive effect, and both were stronger than latanoprost. The scatter plot analysis showed that all PGAs reduced IOP by 15%-20%. At higher IOP (17-18 mmHg), the ocular hypotensive effect was almost the same with latanoprost, travoprost, and tafluprost. In contrast, at lower IOP (12-15 mmHg), the IOP reduction with latanoprost was weaker than with travoprost or tafluprost. Conclusion: This literature review of the ocular hypotensive effects of PGAs in Japanese patients with NTG highlighted that PGAs had different ocular hypotensive effects. Ophthalmologists should understand the IOP-lowering profiles of various PGAs and apply them to patients with NTG on a case-by-case basis.

PMID- 30275681 TI - Oral kallidinogenase improved visual acuity and maintained chorioretinal blood flow levels after treatment for diabetic macular edema. AB - Purpose: This study was designed to investigate the therapeutic effects of oral kallidinogenase medication as an adjuvant therapy in treating patients with diabetic macular edema (DME). Study design: This was a prospective, open-labeled, randomized study. Methods: All patients were given posterior sub-Tenon triamcinolone acetonide (STTA) injection and focal laser treatment session for DME. The patients were subdivided into two groups: 1) those treated with oral kallidinogenase for at least 6 months after local treatment (treated group) and 2) those treated without oral kallidinogenase (untreated group). In this study, best-corrected visual acuity (BCVA), central retinal thickness (CRT), subfoveal choroidal thickness (SCT), and chorioretinal blood flow level were measured in 17 patients (19 eyes). Chorioretinal blood flow levels at the disc and macula were measured by laser speckle flowgraphy and evaluated using the mean blur rate (MBR). These data were measured at baseline and at 1, 3, and 6 months after treatment initiation. Results: BCVA at 6 months after treatment significantly improved in treated group (P<0.05). But the mean CRT after treatment significantly decreased in both groups. There was no significant difference in the mean SCT at baseline between the two groups. The mean SCT after treatment in treated group was significantly thinner than that before treatment (P<0.05). Compared to baseline (100%), MBR at the disc and the macula at 6 months after treatment significantly decreased to 84.8% and 86.2%, respectively, in untreated group (P<0.05), though it remained unchanged at 98.7% and 99.7% in treated group. Conclusion: Oral kallidinogenase medication is useful as an adjuvant therapy to enhance the therapeutic effect of STTA in DME patients. PMID- 30275682 TI - The ophthalmic fallout in Utah after the Great American Solar Eclipse of 2017. AB - Background: Solar retinopathy is a rare ophthalmic disorder resulting from sustained viewing of the sun without protective eyewear. Incidence of solar retinopathy typically increases following a solar eclipse due to attempted visualization of the sun without appropriate eye protection. This paper serves as a case series of all available reported cases of solar retinopathy present in Utah resulting from the August 21st, 2017 solar eclipse. Methods: Twenty-seven patients had presented with concern for vision changes after the solar eclipse and six patients had exam findings consistent with solar retinopathy. Of these six cases, charts were available for three. Results: The common finding in all cases was a central scotoma with a correlating change to the inner segment/outer segment junction on optical coherence tomography. Demographically, all three patients were young males. Conclusion: This data provides insights on populations in Utah at risk for ophthalmic damage and can aid in targeting education programs in the future. PMID- 30275683 TI - Effects of hydroxyethyl starch 130/0.4 on the kidney tissue of rats with ureteral obstruction. AB - Objective: This study was conducted since the effects of colloid solutions on the renal system remain controversial and need to be adequately studied in animals. We aimed to evaluate the effects of hydroxyethyl starch (Voluven) on the kidney tissue of rats with late renal failure due to ureteral obstruction. Materials and methods: Rats were divided into four groups: Group C, control; Group HES, hydroxyethyl starch solution (HES) 130/0.4 (Voluven(r)); Group UUO, unilateral ureteral obstruction (UUO); and Group UUO-HES, UUO-HES 130/0.4 (Voluven(r)). In the groups with ureteral obstruction, the distal part of the right ureter was accessed and sutured through a lower abdominal incision under ketamine anesthesia. Any signs of late-stage renal failure were evaluated after three weeks. Rats in the HES group and the renal failure-HES group were administered with HES 130/0.4 as a single intravenous dose of 20 mL/kg. After a follow-up of 24 hours, intra-abdominal blood sample was collected, and the rats were sacrificed. Biochemical and histopathological parameters were then evaluated. Results: Ureteral obstruction significantly increased urea and creatinine levels. In addition, when the UUO-HES and HES groups were compared, the administration of HES increased urea and creatinine levels in the UUO-HES group. Nitric oxide enzyme activity and malondialdehyde levels have significantly increased in the UUO groups. In addition, HES significantly increased nitric oxide activity and malondialdehyde levels in the UUO-HES group, in comparison with the HES group. The activity of caspases 3 and 8 was significantly increased in the UUO groups. In addition, HES significantly increased the activity of caspases 3 and 8 in the UUO-HES group, in comparison with the HES group. Light microscopy revealed significant changes in the UUO groups, especially in the obstructed kidneys. Conclusion: If indicated, HES should be used with caution in cases of UUO, but not in the cases of bilateral ureteral obstruction. Other aspects of these findings, including the clinical significance and practical applications, merit further experimental and clinical investigation. PMID- 30275684 TI - Glucosamine-paracetamol spray-dried solid dispersions with maximized intrinsic dissolution rate, bioavailability and decreased levels of in vivo toxic metabolites. AB - Purpose: This study is aimed at preparing and testing physicochemical, pharmacokinetic and levels of toxic metabolites of paracetamol and glucosamine solid dispersions intended for multiple deliveries via the parenteral or per oral route. Methods: Solid dispersions were prepared using the spray drying technique at different molar ratios of paracetamol and glucosamine. Characterization of the solid dispersions was carried out using differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), equilibrium solubility and intrinsic dissolution rate. In vivo pharmacokinetics and toxic metabolites of the prepared dispersions were evaluated and compared to those of pure drugs and physical mixtures. Results: Instant water solubility and more than 7-fold increase in dissolution rate led to significantly high plasma drug concentration (>6.5-fold) compared to paracetamol alone. More than 2-fold increase in area under the curve from 0 to 24 h from the dispersions was noticed on the third day of oral dosing to animals. Lower number and concentration followed by the complete disappearance of toxic pathway metabolites were observed on second and third days of dosing with solid dispersions and physical mixtures, respectively. Conclusions: The spray-dried dispersions support safer and more effective delivery of multiple doses of paracetamol, leading to an acceleration of its analgesic actions. Synergism between the analgesic actions of paracetamol and joint protective actions of glucosamine in this combination is expected to facilitate effective treatment of persistent pain-related illnesses such as osteoarthritis. PMID- 30275685 TI - Comparison of the efficacy and survival analysis of neoadjuvant chemotherapy for Her-2-positive breast cancer. AB - Purpose: The objective of this research was to compare the short- and long-term efficacy of the following four neoadjuvant chemotherapy (NAC) regimens: docetaxel/carboplatin/trastuzumab (TCH), docetaxel/epirubicin/cyclophosphamide (TEC), Xeloda/epirubicin/cyclophosphamide followed by Xeloda/docetaxel (XEC-XT), and 5-fluorouracil/epirubicin/cyclophosphamide followed by docetaxel (FEC-T) in human epidermal growth factor receptor-2-positive (Her-2-positive) breast cancer. Patients and methods: According to treatment preferences, 139 patients with Her-2 positive breast cancer were divided into the following four groups: 39 patients in the TCH group, 35 patients in the TEC group, 33 patients in the XEC-XT group, and 32 patients in the FEC-T group. The primary end points were disease-free survival (DFS) and 5-year overall survival (5-year OS). The secondary end points were the efficacy and toxicity of NAC. Results: The TCH, TEC, XEC-XT, and FEC-T groups demonstrated overall response rates of 87.1%, 74.3%, 75.8%, and 62.5% (P=0.031), respectively, and pathological complete response rates of 25.6%, 18.2%, 20.0%, and 18.2% (P=0.041), respectively. The DFS rates for the TCH, TEC, XEC-XT, and FEC-T groups were 84.6%, 62.9%, 65.7%, and 46.9% (P=0.01), respectively. The 5-year OS rates for the TCH, TEC, XEC-XT, and FEC-T groups were 87.2%, 69.7%, 71.4%, and 59.4% (P=0.069), respectively. The mean survival time was 59.3 months (TCH group), 53.5 months (TEC group), 55.3 months (XEC-XT group), and 52.4 months (FEC-T group). The difference in survival among the four groups was statistically significant (P=0.04). Conclusion: In four NAC regimens for the treatment of Her-2-positive breast cancer, the TCH group exhibited better DFS and 5-year OS. The TCH regimen significantly enhanced the pathological complete remission rate of NAC with similar side effects compared to the TEC, XEC-XT, and FEC-T regimens. In terms of long-term efficacy, the XEC-XT treatment was superior to the FEC-T and TEC treatment, and there was no significant difference between the FEC-T and TEC groups. PMID- 30275686 TI - A targeted therapy for melanoma by graphene oxide composite with microRNA carrier. AB - Background: Nowadays, the combination of microRNA (miR) is attracting increased attention in clinical cancer trials. However, the clinical use of miR is highly limited because of certain properties such as instability, low-specificity distribution, and metabolic toxicity. Methods: In order to improve the anti-tumor efficacy and reduce the side effects of miR in treating melanoma, a combination of graphene oxide (GO), chitosan (CS), and a cellular penetrating peptide, MPG, was prepared with solid dispersion method in this research. The research has analyzed the specific components of nano drug-loading complexes GO-CS and GO-CS MPG through characterization research and confirmed the bio-safety of the carrier material GO-CS-MPG. Results: The GO-CS-MPG-miR33a/miR199a nano drug-loading complex was successfully constructed and its medical effectiveness was verified. Through the subcutaneous tumor implantation experiment, an evident effect of the drug-loading complex in inhibiting melanoma cells was proven. Conclusion: Results suggest that GO-CS-MPG may have potential applications in melanoma therapy. PMID- 30275687 TI - A multicomponent frailty intervention for socioeconomically vulnerable older adults: a designed-delay study. AB - Purpose: The primary aim of this study was to evaluate the effectiveness of a 6 month multicomponent intervention on physical function in socioeconomically vulnerable older adults in rural communities. As secondary aims, we evaluated the effectiveness of the intervention on frailty and other geriatric syndromes, sustained benefit at 12 months, and baseline characteristics associated with poor response. Patients and methods: This designed-delay study was conducted in 187 adults (mean age: 77 years; 75% women) who were living alone or on a low income in three rural regions of Korea. A 24-week multicomponent program that consisted of group exercise, nutritional supplementation, depression management, deprescribing medications, and home hazard reduction was implemented with a planned 6-month interval from August 2015 through January 2017. The primary outcome was physical function, measured using the Short Physical Performance Battery (SPPB) score (range: 0-12; minimum clinically important difference >=1) at 6 months. Secondary outcomes included frailty phenotype, sarcopenia, Mini Nutritional Assessment-Short Form score (range: 0-14), Center for Epidemiologic Studies-Depression Scale score (range: 0-60), and falls. Results: At 6 months, the SPPB score increased by 3.18 points (95% CI: 2.89, 3.48) from baseline. The program improved frailty (odds ratio: 0.06; 95% CI: 0.02, 0.16), sarcopenia (odds ratio: 0.32; 95% CI: 0.15, 0.68), Mini Nutritional Assessment-Short Form score by 1.67 points (95% CI: 1.28, 2.06), and Center for Epidemiologic Studies-Depression Scale score by -3.83 points (95% CI: -5.26, -2.39), except for fall (rate ratio: 0.99; 95% CI: 0.69, 1.43). These beneficial effects were sustained at 12 months. Body mass index >=27 kg/m2 and instrumental activities of daily living disability at baseline were associated with poor improvement in the SPPB score. Conclusion: This 24-week multicomponent program had sustained beneficial effects up to 1 year on physical function, frailty, sarcopenia, depressive symptoms, and nutritional status in socioeconomically vulnerable older adults in rural communities. (ClinicalTrials.gov, NCT 02554994). PMID- 30275688 TI - The appeal of the Functional Fitness MOT to older adults and health professionals in an outpatient setting: a mixed-method feasibility study. AB - Purpose: To understand the views and perceptions regarding the Functional Fitness MOT (FFMOT), a battery of functional tests followed by a brief motivational interview, of both the older people undergoing it and the health professionals delivering it. Patients and methods: Physically inactive older adults (n=29) underwent the FFMOT and subsequently attended focus groups to share their perceptions of it and to discuss the barriers, motivators, health behavior change, and scope to improve physical activity (PA) levels. PA levels were recorded at baseline and again at 12 weeks together with a post-intervention questionnaire concerning behavior change. Participating physiotherapists and technical instructors were interviewed. Results: Most participants felt they had learned about their abilities and comparisons with their peers, had a change in perception about the importance of good balance and strength, and felt the FFMOT helped raise their awareness of local and self-directed physical activity opportunities. Most felt their awareness of the need for PA had not changed, but 25% of participants started a new organized PA opportunity. The health professionals perceived the FFMOT as being easy to administer, educating, and motivating for participants to increase their PA. Space, time, finances, and insecurity about having the necessary skills to conduct the FFMOTs were seen as barriers in implementing the FFMOT in daily practice. Conclusion: Over half of those offered the FFMOT accepted it, suggesting it is appealing. However, most participants felt they were already active enough and that their awareness of the need for PA had not changed. There were positive perceptions of the FFMOT from both professionals and older people, but both felt the FFMOT could be held in a community venue. The overall findings suggest that the FFMOT is feasible in the clinical setting, but its effectiveness has yet to be determined. PMID- 30275689 TI - Proton pump inhibitors use is associated with a lower risk of acute exacerbation and mortality in patients with coexistent COPD and GERD. AB - Objective: The effect of antacid therapy for patients with COPD and gastroesophageal reflux disease (GERD) remains unclear. Patients and methods: This nationwide population-based study was conducted using data from Taiwan's National Health Insurance Research Database, and enrolled COPD patients with or without GERD. Patients with COPD who were not prescribed COPD medications were excluded. Patients with GERD who underwent upper gastrointestinal endoscopy or 24 hour pH monitoring and received at least 1 antacid were enrolled as symptomatic GERD group. The primary endpoint was acute exacerbation and mortality. Results: This study included 3,485 patients with COPD and symptomatic GERD, and 13,938 patients with COPD alone and covered 12,806.57 and 56,809.78 person-years, respectively, from 2000 to 2011. After multivariate adjustment, symptomatic GERD was associated with acute exacerbation (adjusted hazard ratio [HR]: 1.35, 95% CI: 1.23-1.48, p<0.0001) and mortality (HR: 1.42, 95% CI: 1.25-1.61, p<0.0001). In the COPD with symptomatic GERD group, use of proton pump inhibitors was associated with a lower risk of acute exacerbation and mortality (acute exacerbation, HR 0.31, 95% CI: 0.20-0.50, p<0.0001; mortality, HR 0.36, 95% CI: 0.20-0.65, p=0.0007), whereas no significant benefit was observed for histamine2 receptor antagonists. Conclusion: Use of proton pump inhibitors was associated with a lower risk of acute exacerbation and mortality in the patients with COPD and symptomatic GERD. PMID- 30275690 TI - Effect of background long-acting beta2-agonist therapy on the efficacy and safety of a novel, nebulized glycopyrrolate in subjects with moderate-to-very-severe COPD. AB - Background: Phase III studies demonstrated efficacy and safety of nebulized glycopyrrolate inhalation solution (GLY) in subjects with COPD. Secondary analyses were performed to examine the effect of background long-acting beta2 agonist (LABA) use on the efficacy and safety of nebulized GLY. Methods: In two 12-week placebo-controlled studies (GOLDEN 3 and GOLDEN 4) and one 48-week, open label active-controlled study (GOLDEN 5), a total of 2,379 subjects were stratified by background LABA use (LABA-yes: n=861; LABA-no: n=1,518) and randomized to placebo vs GLY 25 or 50 ug twice daily, or GLY 50 ug twice daily vs tiotropium (TIO) 18 ug once daily. Lung function, patient-reported outcomes, exacerbations, and safety were assessed. Results: Compared with placebo, pooled data from the 12-week studies showed significant improvements from baseline with GLY 25 and 50 ug across LABA subgroups in trough FEV1 (LABA-yes: 0.101 and 0.110 L; LABA-no: 0.092 and 0.101 L, respectively; P<0.001) and St George's Respiratory Questionnaire total score (SGRQ; LABA-yes: -2.957 and -3.888; LABA-no: -3.301 and -2.073, respectively; P<0.05). Incidence of treatment-emergent adverse events (TEAEs) was similar in LABA subgroups, and lower in GLY 25 ug vs placebo. In the 48-week active-controlled study, GLY and TIO both showed improvement from baseline across LABA subgroups in FEV1 (LABA-yes: 0.106 and 0.092 L; LABA-no: 0.096 and 0.096 L, respectively) and in SGRQ total score (LABA-yes: -5.190 and 3.094; LABA-no: -4.368 and -4.821, respectively). Incidence of TEAEs was similar between GLY and TIO, and across LABA subgroups. Exacerbation rates were similar across treatments and LABA subgroups, and cardiovascular events of special interest were more frequent in the LABA-no subgroup. Nebulized GLY, combined with LABA, did not generate any additional safety signals. Conclusion: Nebulized GLY demonstrated efficacy and was well tolerated up to 48 weeks in subjects with COPD with/without background LABA. PMID- 30275691 TI - The role of plasma N-terminal brain natriuretic pro-peptide in diagnosing elderly patients with acute exacerbation of COPD concurrent with left heart failure. AB - Introduction: Acute exacerbation of COPD (AECOPD) and left heart failure (LHF) commonly exist together in clinical practice. However, the identification of AECOPD concurrent with LHF is currently challenging. Our study aimed to investigate the role of plasma N-terminal brain natriuretic pro-peptide (NT proBNP) in diagnosing elderly patients with AECOPD associated with LHF. Methods and results: LHF was diagnosed in patients with AECOPD according to echocardiographic criteria, and the levels of NT-proBNP in plasma were measured by quantitative electrochemiluminescence assay. Among the 655 patients with AECOPD, 158 (24.1%) had comorbid LHF, whether systolic (n=108, 68.4%) or diastolic (n=50, 31.6%). The plasma concentrations of NT-proBNP in elderly patients with AECOPD associated with LHF were markedly elevated, compared with those with only AECOPD (4,542.5 and 763.0 ng/L, respectively, P<0.01). The receiver operating characteristic curve indicated a diagnostic cutoff value of 1,677.5 ng/L of NT-proBNP in plasma for ascertaining the presence of LHF in AECOPD, with a sensitivity of 87.9%, a specificity of 88.5%, and an accuracy of 88.4%. Conclusion: The plasma level of NT-proBNP may be a useful indicator in diagnosing AECOPD associated with LHF. PMID- 30275692 TI - Altered spontaneous brain activity patterns in strabismus with amblyopia patients using amplitude of low-frequency fluctuation: a resting-state fMRI study. AB - Objective: Previous studies have demonstrated that strabismus or amblyopia can result in markedly brain function and anatomical alterations. However, the differences in spontaneous brain activities of strabismus with amblyopia (SA) patients still remain unclear. This current study intended to use the amplitude of low-frequency fluctuation (ALFF) technique to investigate the intrinsic brain activity changes in SA subjects. Patients and methods: A total of 16 patients with SA (6 males and 10 females) and 16 healthy controls (HCs; 6 males and 10 females) similarly matched in age, gender, and education status were recruited and examined with the resting-state functional MRI. The spontaneous brain activity changes were investigated using the ALFF technique. The receiver operating characteristic curve was performed to classify the mean ALFF signal values of the SA patients from HCs. The correlations between the ALFF values of distinct brain regions and the clinical manifestations in SA patients were evaluated in terms of the Pearson's correlation analysis. Results: Compared with HCs, SA patients had significantly decreased ALFF in the left cerebellum posterior lobe, left middle frontal gyrus, and bilateral thalamus. In contrast, SA patients showed increased ALFF values in the right superior frontal gyrus, right precuneus, left cuneus, and bilateral precentral gyrus. Nonetheless, there was no linear correlation between the mean ALFF values in brain regions and clinical features. Conclusion: Diverse brain regions including vision-related and motion-related areas exhibited aberrant intrinsic brain activity patterns, which imply the neuropathologic mechanisms of oculomotor disorder and vision deficit in the SA patients. PMID- 30275693 TI - Gender differences in the relationships among neurosteroid serum levels, cognitive function, and quality of life. AB - Background: Dehydroepiandrosterone (DHEA), its sulfate ester (DHEA-S), and pregnenolone are neurosteroids that can be synthesized in the brain. Previous studies have hypothesized that these neurosteroids have antiaging, mood enhancing, and cognitive-preserving effects; however, these effects may be gender specific. Therefore, the purpose of this study was to investigate the gender differences in the relationships among neurosteroids (DHEA, DHEA-S, and pregnenolone), cognitive function, and quality of life in healthy individuals. Method: In this cross-sectional study, we enrolled 47 men (mean age: 32.8 years) and 75 women (mean age: 35.4 years) who had no major physical or psychiatric illnesses and measured their serum DHEA, DHEA-S, and pregnenolone. Furthermore, we evaluated the subjects' cognitive function and quality of life using the Brief Assessment of Cognition in Schizophrenia and the World Health Organization Quality of Life Scale, respectively. Results: The serum levels of DHEA and DHEA-S demonstrated significant gender differences, even after controlling for age effect. In the male subjects, the DHEA serum levels were positively correlated with three domains of the World Health Organization Quality of Life Scale, including physical health, social relations, and environmental dimensions. Meanwhile, the DHEA-S levels positively correlated with the performance of working memory, and pregnenolone levels had a positive correlation with working memory, verbal fluency, and Brief Assessment of Cognition in Schizophrenia composite score. However, in the female subjects, we observed a correlation only between the serum levels of DHEA-S and working memory. Conclusion: The findings of our study indicate that neurosteroids play a vital role in cognitive function and quality of life among men but less so among women. Nevertheless, the underlying mechanisms of the gender-specific effect of neurosteroids require further investigation. PMID- 30275694 TI - The microglial activation profile and associated factors after experimental spinal cord injury in rats. AB - Background: Spinal cord injury (SCI) has imposed a great impact on the quality of life of patients due to its relatively young age of onset. The pathophysiology of SCI has been proven to be complicated. Microglia plays an important role in neuroinflammation and second injuries after SCI. Different environment and other factors may determine the microglial activation profile and what role they play. However, neither accurate time-course profiles of microglial activation nor influence factors have been demonstrated in varied SCI models. Methods: A rat compressive SCI model was used. Microglial activation profile and contents of inflammatory factors including IL-1beta, IL-6 and TNF-alpha were detected. Myelination status as well as levels of iron and glutamate concentration, adenosine triphosphate (ATP) and potassium are also assessed. Results: Our results showed that the activated microglia participating in immune-mediated responses peaked at day 7 post SCI and gradually decreased during the following 3 weeks. Contrarily, myelination and oligodendroglia showed an opposite trend, indicating that microglia may be a key factor partly through inflammatory reaction. Iron and glutamate concentration were found to be the highest at day 7 after SCI while both ATP and potassium reached a low valley at the same time. Conclusion: These findings showed a microglial activation profile and the alterations of associated factors after experiment SCI model. Moreover, our data suggest that high iron and glutamate concentration may be released by damaged oligodendroglia and contribute to the activation of microglial after SCI. PMID- 30275695 TI - Speech and language profiles in 4- to 6-year-old children with early diagnosis of autism spectrum disorder without intellectual disability. AB - Purpose: This study aimed to present speech and language data from a community representative group of 4- to 6-year-old children with early-diagnosed autism spectrum disorder (ASD) without intellectual disability (ID). Methods: The study group comprised 83 children 4-6 years of age with ASD without ID. They had been diagnosed with ASD before age 4.5 years and had received intervention at a specialized habilitation center. At 2-year follow-up, their language abilities were evaluated comprehensively by two speech-language pathologists using a battery of assessments. Receptive and expressive language and phonology were examined. The phonology evaluation included measures of phonological speech production and of phonological processing. Results: Results revealed that almost 60% had moderate-severe language problems. Nearly half exhibited combined expressive and receptive language problems, of which a majority also had phonology problems. Phonological speech problems were found in 21% of the total group. Conclusion: The findings underscore the importance of considering speech/language disorders in children with ASD without ID, since they usually attend mainstream classes but need specific educational adaptations. PMID- 30275696 TI - CBT-I and HT-I group therapy for adults with insomnia in comparison to those with insomnia and comorbid depression - a pilot study. AB - Purpose: The aim of this study was to examine the effectiveness of a combined cognitive-behavioral therapy for insomnia (CBT-I) and hypnotherapy for insomnia (HT-I) program for insomnia patients with or without additional depression regarding depressive symptoms and various sleep parameters. Patients and methods: A sample of 63 patients suffering from insomnia received a six-session sleep intervention, which combined cognitive-behavioral and hypnotherapeutical elements. Due to violating exclusion criteria, data of 37 patients were analyzed. Ten patients had insomnia comorbid with depression, whereas 27 patients had insomnia only. Sleep diaries were implemented to measure various sleep parameters, whereas depressive symptomatology was assessed with the anxiety and depression scale and Symptom-Checklist-90-R at baseline, before and after the intervention, as well as at 3-months follow-up. Results: Depressive symptoms decreased from pre to post measurement and follow-up for patients with insomnia comorbid with depression, whereas scores of patients with only insomnia remained relatively on a low level. Both groups showed a significant increase of sleep efficiency and a significant decrease of the duration of wake after sleep onset. However, only patients with insomnia and depression revealed a significant reduction of sleep-onset latency and a higher level of regeneration. Nondepressive insomniacs, on the other hand, showed a significant increase of performance from post measurement to follow-up. For both groups, no change over time was found for number of wake after sleep onset, total sleep time, mood in the morning and evening. Conclusion: Combining CBT-I and HT-I is effective in reducing depressive symptoms and improving sleep. Therefore, nonresponders to other forms of therapy, eg, pharmacological, interpersonal, or cognitive behavioral therapy, might benefit from the combined CBT-I/HT-I intervention. PMID- 30275697 TI - Automatic epilepsy detection using fractal dimensions segmentation and GP-SVM classification. AB - Objective: The most important part of signal processing for classification is feature extraction as a mapping from original input electroencephalographic (EEG) data space to new features space with the biggest class separability value. Features are not only the most important, but also the most difficult task from the classification process as they define input data and classification quality. An ideal set of features would make the classification problem trivial. This article presents novel methods of feature extraction processing and automatic epilepsy seizure classification combining machine learning methods with genetic evolution algorithms. Methods: Classification is performed on EEG data that represent electric brain activity. At first, the signal is preprocessed with digital filtration and adaptive segmentation using fractal dimensions as the only segmentation measure. In the next step, a novel method using genetic programming (GP) combined with support vector machine (SVM) confusion matrix as fitness function weight is used to extract feature vectors compressed into lower dimension space and classify the final result into ictal or interictal epochs. Results: The final application of GP-SVM method improves the discriminatory performance of a classifier by reducing feature dimensionality at the same time. Members of the GP tree structure represent the features themselves and their number is automatically decided by the compression function introduced in this paper. This novel method improves the overall performance of the SVM classification by dramatically reducing the size of input feature vector. Conclusion: According to results, the accuracy of this algorithm is very high and comparable, or even superior to other automatic detection algorithms. In combination with the great efficiency, this algorithm can be used in real-time epilepsy detection applications. From the results of the algorithm's classification, we can observe high sensitivity, specificity results, except for the Generalized Tonic Clonic Seizure (GTCS). As the next step, the optimization of the compression stage and final SVM evaluation stage is in place. More data need to be obtained on GTCS to improve the overall classification score for GTCS. PMID- 30275699 TI - The evolving role of social media in health-care delivery: measuring the perception of health-care professionals in Eastern Saudi Arabia. AB - Purpose: The objective of this study is to evaluate the perception of health-care professionals in Saudi Arabia toward the usages of social media in health-care delivery. Methods: In this cross-sectional study, an online-based questionnaire was distributed among the health-care professionals residing in the eastern region of Saudi Arabia. Their perception toward the uses of social media in health-care service delivery was evaluated by analyzing their attitude toward its benefits and risks involved. Results: The sample size was 120 participants, and 80% of them agreed with the benefits of using social networks in health-care services and considered that the use of these technologies in the provision of health services improves their professional knowledge and is a suitable tool for patient education and public health awareness. However, some respondents (20%) believed that there are several risks associated with the use of social media, such as ethical or legal challenges, the risk to the patient's health status, or the breaching of the privacy and confidentiality of the patient. Conclusion: The results of this research indicate that social media can be a useful tool by which physicians may promote their services and publish general health information. However, there are potential problems in the use of social networks that can have negative consequences for patients and HCPs. This implies that precautions must be taken to avoid ruptures of patient privacy and other risks that can result in legal action against health professionals damaging their image and professional status. The study also found that the participants are willing to use social media for professional purposes. PMID- 30275698 TI - Antihypertensive effect of the mineralocorticoid receptor antagonist eplerenone: a pooled analysis of patient-level data from comparative trials using regulatory approved doses. AB - Purpose: Several options are available for the treatment of hypertension; however, many treated patients are still not below blood pressure (BP) target. Eplerenone, a selective mineralocorticoid receptor antagonist, is an approved treatment option for the management of patients with hypertension in a number of countries. This patient-level pooled analysis was conducted to document the efficacy and safety/tolerability of eplerenone at the dosages approved for use in hypertension in comparison to placebo or other approved antihypertensive agents. Methods: Seventeen Phase III studies conducted in patients with mild-to-moderate hypertension in the Eplerenone Hypertension Clinical Program were reviewed; eleven met the selection criteria. The primary endpoint was change from baseline in seated diastolic BP and seated systolic BP measured at the end of the study. Results: A total of 2,698 patients were included in this per-protocol analysis. In patients treated for at least 6 weeks with a stable dose of eplerenone, doses of 50 mg daily and 100 mg daily were associated with greater reductions of seated systolic BP and seated diastolic BP compared with placebo (P<0.001) and active controlled studies (P< 0.033). In the analysis of covariance model testing of the contribution of four factors (age, body mass index [BMI], history of cardiovascular disease, and diabetes) on the BP lowering effects of eplerenone, only BMI and age were associated with small though statistically significant changes in BP (<0.2 mmHg). Eplerenone was well tolerated; headache was the most common adverse event for patients in any group. Severe hyperkalemia (serum potassium level >6.0 mmol/L) occurred in up to 0.4% in the eplerenone groups, 0.4% in the placebo group, and 0.1% in the active-control group. Conclusion: This patient-level pooled analysis provides robust evidence that eplerenone, at 50 mg or 100 mg daily, was effective in lowering BP in patients with mild-to-moderate hypertension and was well tolerated. PMID- 30275701 TI - Feasibility of radical hysterectomy in women with FIGO stage IIB cervical cancer: an observation study of 10-year experience in a tertiary center. AB - Purpose: Although definitive chemoradiotherapy is considered as a standard of care for FIGO stage IIB cervical cancer in many countries, the role of surgery remains controversial. We aimed to evaluate the feasibility and outcomes of patients with FIGO stage IIB cervical cancer who received radical surgery in China. Patients and methods: A total of 74 women with FIGO stage IIB cervical cancer were treated with radical hysterectomy, with or without adjuvant radio/chemoradiotherapy, at the Obstetrics and Gynecology Hospital of Fudan University between 2004 and 2015. Medical charts and clinical data were retrospectively reviewed. The Kaplan-Meier method and Cox regression models were used for survival analyses. In addition, prognostic nomograms predicting overall survival (OS) and progression-free survival (PFS) were constructed. Results: Pathological parametrial involvement (PMI) was only identified in 28.3% (21/74) of all patients and 47.3% (9/19) of patients without neoadjuvant treatment. Major surgical complications, including bladder fistula, intestinal obstruction and ureteral injury, were found in 6.8% (5/74) of patients. Although the use of imaging technologies including magnetic resonance imaging (MRI)/positron emission tomography-computed tomography (PET-CT) has increased after 2010 compared to that prior to 2010, the accuracy of MRI/PET-CT in detecting pathological PMI was lower than that of physical examination under anesthesia (P<0.05). Neoadjuvant treatment was the only risk factor affecting the accuracy of pre- and postoperative accordance of PMI (OR: 3.283 [95% CI: 1.363-7.908], P=0.008). The 2 and 5-year OS rates were 84.1% and 68.9%, respectively, while the 2- and 5-year cumulative recurrence rates were 26.9% and 39.9%, respectively. Cox regression analyses indicated that pre- and postoperative accordance of PMI, common iliac lymph node metastasis and major surgical complications were significant prognostic factors for both OS and PFS. Conclusion: Radical hysterectomy might be a feasible alternative for FIGO stage IIB cervical cancer. As pre- and postoperative accordance of PMI is relatively low, strategies to appropriately select patients who will benefit from surgery via pretreatment evaluation need to be further investigated. PMID- 30275700 TI - Analysis, Nutrition, and Health Benefits of Tryptophan. AB - Tryptophan is an essential plant-derived amino acid that is needed for the in vivo biosynthesis of proteins. After consumption, it is metabolically transformed to bioactive metabolites, including serotonin, melatonin, kynurenine, and the vitamin niacin (nicotinamide). This brief integrated overview surveys and interprets our current knowledge of the reported multiple analytical methods for free and protein-bound tryptophan in pure proteins, protein-containing foods, and in human fluids and tissues, the nutritional significance of l-tryptophan and its isomer d-tryptophan in fortified infant foods and corn tortillas as well the possible function of tryptophan in the diagnosis and mitigation of multiple human diseases. Analytical methods include the use of acid ninhydrin, near-infrared reflectance spectroscopy, colorimetry, basic hydrolysis; acid hydrolysis of S pyridylethylated proteins, and high-performance liquid and gas chromatography mass spectrometry. Also covered are the nutritional values of tryptophan fortified infant formulas and corn-based tortillas, safety of tryptophan for human consumption and the analysis of maize (corn), rice, and soybean plants that have been successfully genetically engineered to produce increasing tryptophan. Dietary tryptophan and its metabolites seem to have the potential to contribute to the therapy of autism, cardiovascular disease, cognitive function, chronic kidney disease, depression, inflammatory bowel disease, multiple sclerosis, sleep, social function, and microbial infections. Tryptophan can also facilitate the diagnosis of certain conditions such as human cataracts, colon neoplasms, renal cell carcinoma, and the prognosis of diabetic nephropathy. The described findings are not only of fundamental scientific interest but also have practical implications for agriculture, food processing, food safety, nutrition, and animal and human health. The collated information and suggested research need will hopefully facilitate and guide further studies needed to optimize the use of free and protein-bound tryptophan and metabolites to help improve animal and human nutrition and health. PMID- 30275702 TI - Osteopontin promotes cancer cell drug resistance, invasion, and lactate production and is associated with poor outcome of patients with advanced non small-cell lung cancer. AB - Background: Osteopontin (OPN), a member of the small integrin binding ligand N linked glycoprotein family, has been analyzed in numerous types of human malignancy. Purpose: The present study detected the expression levels of OPN and evaluated its role in tumor progression in patients with non-small cell lung cancer (NSCLC). Patients and methods: OPN expression levels were detected using immunohistochemistry in 101 NSCLC tumors. The mRNA and protein levels have significant difference between advanced NSCLC and stage I/II NSCLC. The drug resistance, invasive ability and lactate production of NSCLC cancer cell lines (A549 and SK-MES-1) were detected in cancer cells with the disturbance of OPN. Results: Immunostaining indicated that OPN was primarily expressed in the cytoplasm of NSCLC cells. Moreover, OPN correlates with NSCLC clinical traits. The results demonstrated that OPN expression levels significantly correlated with cancer differentiation, distant metastasis and the efficacy of platinum-based treatment. Notably, the results identified OPN expression levels as a potential factor for predicting the response of cells to first-line platinum-based chemotherapy using multivariate analysis, as well as predicting cancer differentiation and distant metastasis. Additionally, the abrogation of OPN levels reduced lactate production in NSCLC cells and occurred along side with the downregulation of lactate dehydrogenase A (LDHA). Conclusion: The results of the current study suggest that OPN may be able to predict poor prognosis and cisplatin resistance in patients. PMID- 30275703 TI - PD1/PDL1 inhibitors for the treatment of advanced urothelial bladder cancer. AB - Introduction: Until recently, systemic chemotherapy was the only option for treating bladder cancer and outcomes remained dismal. After a long gap of no progress for 40 years, immuno-therapy with checkpoint inhibitors (PDL1 and PD1) has revolutionized the treatment paradigm of bladder cancer, with five approved agents to treat platinum-refractory bladder cancer since the first approval of atezolizumab in May 2016. Methods: This review summarizes the most recent data on approved checkpoint inhibitors currently used in management of advanced bladder cancer. Early- and late-phase trials of the five checkpoint inhibitors (pembrolizumab, nivolumab, atezolizumab, durvalumab, and avelumab) in advanced bladder cancer are reviewed in detail. This review also describes the potential application of PD1/PDL1 inhibitors in adjuvant and neoadjuvant settings and non muscle-invasive bladder cancer, as well as with radiation in muscle-invasive bladder cancer treatment. The role of PDL1 and tumor-mutation burden and clinical considerations in choosing a particular immunotherapy are also discussed. Results: The approved checkpoint inhibitors (PD1 and PDL1 inhibitors) have similar efficacy and safety profiles in metastatic platinum-refractory bladder cancer, but they vary in dose and frequency and cost burden. However, only pembrolizumab has shown superiority over standard chemotherapy in a randomized Phase III setting so far. In addition, in the first-line setting for cisplatin ineligible patients, both pembrolizumab and atezolizumab are US Food and Drug Administration-approved and well tolerated. There is a lack of consensus on the utility of testing for PDL1 as a predictive biomarker, as patients with no PDL1 expression also derive some clinical benefit. Tumor-mutation burden is another predictive biomarker, but needs further validation. Conclusion: Immunotherapy has offered a glimmer of hope to patients with bladder cancer. The current landscape is rapidly evolving, with novel immunotherapy-combination trials to improve outcomes further and evaluate predictive biomarkers to help identify patients most likely to benefit from such therapies. PMID- 30275704 TI - Prognostic value of miR-17-5 p in gastrointestinal cancers: a systematic review and meta-analysis. AB - Background: There are accumulating studies investigating the aberrant expression of microRNAs in tumor patients. As an important member of miR-17/92 cluster, miR 17-5 p has been identified as a potential prognostic factor for survival in tumor patients. We conducted this meta-analysis aimed to assess the effect of miR-17-5 p as a prognostic biomarker for gastrointestinal tumor patients. Materials and methods: Eligible studies were enrolled by searching the online databases of PubMed, Embase, Web of Science, China National Knowledge Infrastructure, and WanFang Data until September 2017. We calculated pooled hazard ratios (HRs) and 95% CI of miR-17-5 p for overall survival and disease-free survival. Results: In the categorical variable analysis, we identified 11 studies with 1,279 patients. The pooled analyses suggested that overexpression of miR-17-5 p may predict poor overall survival (HR = 1.86, 95% CI: 1.55-2.25, P<0.001) and disease-free survival (HR = 1.43, 95% CI: 1.01-2.03, P=0.046) in patients with gastrointestinal tumors. Subgroup analysis showed the pooled HR of overall survival was more significant in tissue specimen, Asian patients, and digestive tract tumors. But there was no correlation between the outcomes and European patients. Conclusions: This meta-analysis suggested that miR-17-5 p has predictive effects on overall survival and disease-free survival of patients with gastrointestinal tumors. PMID- 30275705 TI - Application of weighted gene co-expression network analysis to identify key modules and hub genes in oral squamous cell carcinoma tumorigenesis. AB - Purpose: Oral squamous cell carcinoma (OSCC) is one of the most common malignant diseases worldwide, yet its molecular mechanisms are largely unknown. We aimed to construct gene co-expression networks to identify key modules and hub genes involved in the pathogenesis of OSCC. Patients and methods: We used dataset GSE30784 to construct co-expression networks by weighted gene co-expression network analysis (WGCNA). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed by Database for Annotation, Visualization and Integrated Discovery (DAVID). Hub genes were screened and validated by other datasets. Results: Turquoise and brown modules were found to be the most significantly related to tumorigenesis. Functional enrichment analysis showed that the turquoise module was associated with cell-cell adhesion, extracellular matrix and collagen catabolic process. A total of 10 hub genes (MMP1, TNFRSF12A, PLAU, FSCN1, PDPN, KRT78, EVPL, GGT6, SMIM5 and CYSRT1) were identified and validated at transcriptional and translational levels. Their genetic alteration and survival analysis were also revealed. Conclusion: We identified two modules and 10 hub genes, which were associated with the tumorigenesis of OSCC. The two modules provided references that will advance the understanding of mechanisms of tumorigenesis in OSCC. Moreover, the hub genes may serve as biomarkers and therapeutic targets for precise diagnosis and treatment of OSCC in the future. PMID- 30275706 TI - The predictive ability of plasma ESR1 mutations for the efficacy of endocrine therapy in hormone-receptor-positive advanced breast cancer. AB - Purpose: The predictive ability of plasma ESR1 mutations for outcomes among patients with advanced breast cancer undergoing endocrine therapy (ET) remains disputable. We performed a comprehensive meta-analysis of published studies to clarify the impact of plasma ESR1 mutations on clinical outcomes for patients after subsequent ET. Materials and methods: An electronic search was performed to identify eligible studies. Studies analyzing progression-free survival (PFS) and/or overall survival (OS) according to plasma ESR1 mutation status after subsequent ET were included. HRs were calculated using a fixed- or random-effects model according to heterogeneity. Pooled HRs and 95% CIs were used to estimate the effects. Results: Six studies including 705 patients with advanced breast cancer met the inclusion criteria. The impact of plasma ESR1 mutations on PFS and OS after subsequent ET was reported in six studies (seven groups) and two studies, respectively. Meta-analysis results showed that the pooled HR for ESR1 mutations was 1.70 (95% CI, 1.05-2.74; P=0.03) for OS, which was statistically significant for predicting poor survival, and 1.56 (95% CI, 1.13-2.14; P=0.006) for PFS; however, Begg's and Egger's test results identified the presence of bias. The trim-and-fill method was used, and after incorporation of the imputed studies, the HR was 1.16 (95% CI, 0.88-1.53, P=0.30) for PFS, which indicates that plasma ESR1 mutation had no effect on PFS after subsequent ET. Subgroup analysis suggested that plasma ESR1 mutations were correlated with shorter PFS (HR, 1.98; 95% CI, 1.12-3.51; P=0.02) in patients subsequently treated with aromatase inhibitors (AIs), whereas no association with PFS was observed for patients subsequently treated with non-AI ET (HR, 1.08; 95% CI, 0.85-1.38; P=0.54) or fulvestrant (HR, 1.03; 95% CI, 0.79-1.34; P=0.83). Conclusion: The current meta-analysis demonstrates that plasma ESR1 mutation status is not a predictor of ET efficacy for all drugs without distinction in patients with hormone-receptor-positive advanced breast cancer. ESR1 mutation predicted a poor response to AIs, whereas it was not predictive of non-AI ET efficacy, especially for fulvestrant. PMID- 30275707 TI - Oldhamianoside inhibits the growth of ovarian cancer both in vitro and in vivo via adjusting inflammation and angiogenesis signals. AB - Objective: The aim of this study was to determine the effects and possible mechanisms of oldhamianoside on the growth of human ovarian cancer both in vitro and in vivo. Materials and methods: CCK-8 assay was applied to estimate the effect of oldhamianoside on cell proliferation inhibition in vitro. Nude mice bearing human ovarian SKOV3 xenograft tumors were treated with oldhamianoside to investigate the effects of compound administration on tumor growth in vivo. To further investigate the mechanisms of inhibition effects of oldhamianoside on ovarian cancer growth in vivo, the levels of TNF-alpha, IL-6, and MCP-1 in plasma from the mice were measured by ELISA. Western blot was used to detect the expression of angiogenesis- and/or apoptosis-related proteins. Results: We found that oldhamianoside treatment inhibited SKOV3 proliferation and growth both in vitro and in vivo. Meanwhile, the levels of TNF-alpha, IL-6, and MCP-1 in plasma were markedly suppressed in oldhamianoside-treated mice. Additionally, oldhamianoside treatment inhibited the expression of VEGF and VEGFR2 and decreased the expression of caspase-3 and Bax/Bcl-2 ratio. Conclusion: Our data indicate that oldhamianoside has an obvious inhibition effect on SKOV3 proliferation, and the mechanisms might be related to inhibition of cell growth, apoptosis induction, and adjusting the inflammatory response and angiogenesis signal. PMID- 30275708 TI - Phenformin and metformin inhibit growth and migration of LN229 glioma cells in vitro and in vivo. AB - Background: Malignant glioma is refractory to conventional treatment, highlighting a need to develop novel efficacious therapies. Biguanides, a class of oral antidiabetic drug, have been thought to inhibit proliferation and metastasis in a variety of cancers. Purpose: The objective of this study was to investigate the affections of biguanides, phenformin (Phen) and metformin (Met), on growth and migration of glioma cells LN229 in vitro and in vivo. Methods: Glioma cells LN229 were treated with Phen or Met, then cell proliferation and death were evaluated by MTT assay and PI stain, and cell cycle were evaluated using flow cytometric analysis, meantime wound healing assay and transwell migration assay were performed to detect cell migration ability. In addition, LN229 were injected in thigh of nude mice, and the mice were treated with Phen or Met to detect the effect of Phen and Met in vivo. Results: Phen and Met could significantly inhibit cell growth through inhibiting cell proliferation, promoting cell death and disturbing cell cycle, and these drugs also could inhibit cell colony formation in glioma cells LN229 in vitro. Meanwhile, both Phen and Met could significantly inhibit cell migration of LN229 in vitro, through effecting the expression of E-cadherin and Vimentin. In addition, both Phen and Met inhibited the growth and migration of LN229 in a tumor xenograft model. Furthermore, Phen and Met were associated with the increased level of ROS of cell mitochondrial, and ROS inhibitor NAC could significantly rescue the cell death induced by Phen and Met. Conclusion: Phen and Met displayed powerful antitumor effects of LN229, and our findings powerfully suggest the possibility of Phen and Met being used as an adjuvant agent in the treatment of glioma patients. PMID- 30275709 TI - Upregulation of the alternative splicing factor NOVA2 in colorectal cancer vasculature. AB - Background: Tumor-specific isoforms generated by alternative splicing (AS) are demonstrated to contribute to tumor progression and can represent potential biomarkers. NOVA2 is an AS factor that in physiological conditions regulates endothelial cells' (ECs) polarity and vessel lumen maturation, likely by mediating AS of apical-basal polarity regulators. However, NOVA2 expression in tumor ECs and its regulation have never been investigated. Methods: To elucidate this, 40 colorectal cancer patients were enrolled and NOVA2 expression was investigated by immunohistochemistry in samples bearing both the normal mucosa and the tumor tissue. Results: NOVA2 was found expressed in ECs of tumor vasculature and, importantly, it was upregulated in tumor ECs with respect to normal mucosa ECs in all cases (P<0.001). The same samples analyzed by immunohistochemistry for the expression HIF1alpha, a marker of hypoxia, showed a positive and significant association with NOVA2 levels (P=0.045). Of note, NOVA2 was upregulated by hypoxia also in an in vitro ECs model. Conclusion: Our results provide, for the first time, evidence of NOVA2 expression and upregulation in tumor ECs and highlight hypoxia as a potential regulatory factor. These findings open a completely new perspective to study tumor vasculature and to uncover NOVA2 as a potential source of biomarkers and therapeutic targets based on AS isoforms. PMID- 30275710 TI - Comparison of short-term outcomes between minimally invasive McKeown and Ivor Lewis esophagectomy for esophageal or junctional cancer: a systematic review and meta-analysis. AB - Purpose: Minimally invasive esophagectomy is increasingly performed for esophageal or gastroesophageal junctional cancer, with advantages of improved perioperative outcomes in comparison with open esophagectomy. McKeown and Ivor Lewis are widely used procedures of minimally invasive esophagectomy, and there have been controversies on which one is preferred for patients with resectable esophageal or junctional cancer. Patients and methods: This review was registered at the International Prospective Register of Systematic Reviews (number CRD42017075989). Studies in PubMed, Embase, Web of Science, the Cochrane Library, and ClinicalTrials.gov were thoroughly investigated. Eligible studies included prospective and retrospective studies evaluating short-term outcomes of minimally invasive McKeown esophagectomy (MIME) vs minimally invasive Ivor Lewis esophagectomy (MILE) in patients with resectable esophageal or junctional tumors. Main parameters included anastomotic leak and 30-day/in-hospital mortality. Overall incidence rates (ORs)/weighted mean difference (WMD) with 95% confidence intervals (CIs) were calculated by employing random-effects models. Results: Fourteen studies containing 3,468 cases were included in this meta-analysis. Age, male sex, and American Joint Committee on Cancer (AJCC) stage between the 2 groups were not statistically different. MIME led to more blood loss, longer operating time, and longer hospital stay than MILE. MIME was associated with higher incidence of pulmonary complications (OR =1.96, 95% CI =1.28-3.00) as well as total anastomotic leak (OR =2.55, 95% CI =1.40-4.63), stricture (OR =2.07, 95% CI =1.05-4.07), and vocal cord injury/palsy (OR =5.62, 95% CI =3.46-9.14). In addition, the differences of R0 resection rate, number of lymph modes retrieved, blood transfusion rate, length of intensive care unit stay, incidence of cardiac arrhythmia, and Chyle leak between MIME and MILE were not statistically significant. Notably, incidence of severe anastomotic leak (OR =1.28, 95% CI =0.73-2.24) and 30-day/in-hospital mortality (OR =1.76, 95% CI =0.92-3.36) as well as 90-day mortality (OR =2.22, 95% CI =0.71-6.98) between the 2 procedures were also not significantly different. Conclusion: This study suggests that MIME and MILE are comparable with respect to clinical safety. MILE may be a better option when oncologically and clinically suitable. MIME is still a safe alternative procedure when clinically indicated. However, this evidence is at risk for bias; randomized controlled trials are needed to validate or correct our results. PMID- 30275712 TI - SNHG8 is identified as a key regulator in non-small-cell lung cancer progression sponging to miR-542-3p by targeting CCND1/CDK6. AB - Background: Recently, various dynamically expressed lncRNAs are known to play critical roles in cancer progression. Small nucleolar RNA host genes (SNHG), a stable cytoplasmic lncRNA, which have been widely reported to act as an oncogene in non-small cell lung cancer (NSCLC). As an important member of SNHG, SNHG8 have been suggested to over-expressed in several cancer disease, while the biological function in NSCLC remains unclear. Purpose: Here we investigated the biological function and underlying mechanism of SNHG8 in human NSCLC. Patients and methods: The relationship between SNHG8 expression and clinicopathologic characteristic in NSCLC patients were observed from January 2014 to December 2014 in 120 NSCLC patients. The expression of SNHG8 were analyzed by qRT-PCR assay in cancer tissues and cells. Cell proliferation ability were detected in NSCLC cells by CCK 8 assay. Flow cytometric analysis were performed to detected the cell apoptosis and cell cycle. Luciferase assay and Western blot assay were performed on NSCLC cells to detected the underlying mechanism of SNHG8 in NSCLC. Moreover, Tumor xenografts in nude mice were performed to detected the in vivo function of SNHG8. Results: SNHG8 was over-expressed in NSCLC tissues and cells. Patients with high SNHG8 expression have poorer overall survival (OS) and progression-free survival (PFS) than the patients with low SNHG8 expression. SNHG8 knockdown inhibited NSCLC cell proliferation in vitro and in vivo, arrested cell cycle in the G0/G1 phase via targeting miR-542-3p/CCND1/ CDK6, and induced cell apoptosis via activation of Caspase-3. Conclusion: SNHG8 negatively regulated miR-542-3p in NSCLC progression by regulating downstream effectors including CCND1 and CDK6. SNHG8 showed great potential for the application in the treatment of NSCLC. PMID- 30275711 TI - LINK-A promotes cell proliferation through the regulation of aerobic glycolysis in non-small-cell lung cancer. AB - Purpose: Non-small-cell lung cancer (NSCLC) is the one of the most common malignancies worldwide, and occurs at a higher frequency in male individuals. Little is known about the role of the long intergenic noncoding RNA for kinase activation (LINK-A) in NSCLC, so in the present study we assessed its potential role on cell proliferation in NSCLC. Methods: Expression levels of LINK-A in NSCLC tissues and cell lines were detected by quantitative reverse-transcription polymerase chain reaction. LINK-A was knocked down and overexpressed separately in A549 cells and NCI-H1299 cells. The effect of LINK-A expression on cell proliferation was determined by MTT assay. The correlation between LINK-A and hexokinase II (HKII) expression was investigated by Western blot and HKII Activity Assay. Glucose consumption and lactate production assay were used to investigate the aerobic glycolysis in NSCLC cells. The effect of LINK-A in vivo was determined by xenograft assay. Results: LINK-A expression levels were increased in NSCLC tissues compared with normal tissues. Moreover, LINK-A expression was positively correlated with NSCLC clinicopathological characteristics and survival rate, while knockdown of LINK-A reduced NSCLC cell proliferation. LINK-A expression was also positively correlated with HKII, and NSCLC cells with low LINK-A expression were found to have significantly reduced HKII protein expression, accompanied by a reduction in enzyme activity levels. Both in vitro and in vivo experiments showed that LINK-A expression affected glucose consumption and lactate production through regulation of HKII expression. Conclusion: These data suggest that the functions of LINK-A in NSCLC might play a key role in tumor progression and that LINK-A could be a promising predictive biomarker and potential therapeutic target for NSCLC. PMID- 30275713 TI - Efficacy and safety of trastuzumab as maintenance or palliative therapy in advanced HER2-positive gastric cancer. AB - Background: Human epidermal growth factor receptor 2 (HER2)-positive gastric cancer (GC) is a unique subtype of this disease. Few studies focus on the feasibility of trastuzumab as maintenance or palliative therapy for patients with HER2-positive advanced GC. Patients and methods: We retrospectively analyzed the data of 11 patients, evaluated the efficacy and safety of trastuzumab, and attempted to investigate the prognostic factors for trastuzumab treatment. Among the 11 patients, one achieved partial response (PR), six achieved stable disease (SD), and four were evaluated as progressive disease (PD). Results: The overall response rate (ORR) was 9.10%, and the disease control rate (DCR) was 63.64%. The median overall survival (OS) was 6.10 months, and the median progression-free survival (PFS) was 6.10 months. A significant association was found between trastuzumab treatment cycles and efficacy (P=0.027), cycles and PFS (P=0.001), and cycles and OS (P=0.005). Among the five patients who accepted more than five cycles of trastuzumab, the median OS and median PFS achieved 23.83 months and 14.67 months, respectively. Moreover, we have found the correlation between tumor marker changes and efficacy (P=0.002) and HER2 status and PFS (P=0.027). No association was found between HER2 status and OS (P=0.597). Conclusion: The most common adverse events were left ventricular ejection fraction (LVEF) reduction, fatigue, and anorexia. LVEF reduction was found in seven of 11 patients, but the absolute decline in the LVEF was within 10% from the baseline. The results of this study suggest that trastuzumab is a feasible option as maintenance or palliative therapy for patients with HER2-positive metastatic GC. PMID- 30275714 TI - Lentivirus-mediated shRNA targeting MUTYH inhibits malignant phenotypes of bladder cancer SW780 cells. AB - Objectives: MUTYH is a protein-coding gene that takes part in base excision repair. Many previous studies have reported that MUTYH is directly related to hereditary adenomatous polyposis and colorectal cancer and is also associated with other cancers. However, the relationship between MUTYH and bladder cancer (BC) is unknown. Materials and methods: The expression of MUTYH and clinical characteristics of BC were collected from databases including The Cancer Genome Atlas and Cancer Cell Line Encyclopedia. RNA sequencing and quantitative real time PCR were used to detect MUTYH expression in SW780 BC cells. The level of MUTYH was stably downregulated by lentivirus-mediated vector in SW780 cells. Cell proliferation was evaluated using Cell Counting Kit-8 assay and 5-ethynyl-20 deoxyuridine assay, migration was detected using scratch assay and Transwell assay, and apoptosis was determined using ELISA. Results: MUTYH was upregulated in BC tissues and SW780 cells and its expression level was positively associated with the stage and grade of carcinomas. MUTYH was successfully downregulated in SW780 cells by transducing with a lentivirus-mediated shRNA targeting MUTYH. MUTYH knockdown inhibited the proliferation and migration and induced apoptosis in SW780 cells. Conclusion: Our data suggest that MUTYH is a new participant in bladder urothelial carcinoma. MUTYH may play a role as a biomarker and therapeutic target in BC. PMID- 30275716 TI - Corrigendum. AB - [This corrects the article DOI: 10.1177/1179554918782477.]. PMID- 30275718 TI - Doubling the known endemic species diversity of New Caledonian armored scale insects (Hemiptera, Diaspididae). AB - Fourteen species of armored scale insects are known only from New Caledonia. Here, the adult female of fourteen more are described: Agrophaspisansevatae sp. n., Aonidiamontikoghis sp. n. , Aonidiapauca sp. n., Fernaldannawhita sp. n., Furcaspiscostulariae sp. n., Greeniellacasuarinae sp. n., Greenielladacrydiae sp. n., Lepidosaphesmonticola sp. n., Leptaspispege gen. et sp. n., Leucaspismontikoghis sp. n., Melanaspisnothofagi sp. n., Neomorganianothofagi sp. n., Pseudaonidiadugdali sp. n., and Pseudaonidiayateensis sp. n. We note that the diversity of New Caledonian armored scale insects appears to have resulted more from trans-oceanic dispersal than in situ speciation. PMID- 30275717 TI - New record of Epistylishentscheli (Ciliophora, Peritrichia) as an epibiont of Procambarus (Austrocambarus) sp. (Crustacea, Decapoda) in Chiapas, Mexico. AB - Epibiosis is very common between crustaceans and ciliates where the calcified surface of the crustacean body provides a suitable substrate for ciliate colonization. The aim of this contribution is to provide data about a new record between the epistylid ciliate Epistylishentscheli Kahl, 1935, and the crayfish Procambarus (Austrocambarus) sp. The distribution of the epistylid on the basibiont body and its cellular/colonial characteristics were analyzed. Procambarus (Austrocambarus) sp. harbored colonies of E.hentscheli only on the pereiopods. This is the first record of this peritrich ciliate as an epibiont on Crustacea, having been previously found on algae and fish. PMID- 30275715 TI - Dual inhibitor of PI3K and mTOR (NVP-BEZ235) augments the efficacy of fluorouracil on gastric cancer chemotherapy. AB - Purpose: NVP-BEZ235 is a recently developed dual inhibitor of PI3K and mTOR and shows good inhibitory effects on several types of tumors. However, the efficacy of NVP-BEZ235 on gastric cancer therapy remains unclear. This study aimed to investigate the potential of NVP-BEZ235 as a new agent to enhance chemotherapy for gastric cancer. Methods: Human gastric cancer MKN-45 cells or nude mice xenografted with MKN-45 cells were treated by NVP-BEZ235 and fluorouracil (5-FU) alone or in combination. The proliferation, invasion, apoptosis, and chemoresistance of gastric cancer cells were examined in vivo and in vitro. Results: In vitro, combined treatment with NVP-BEZ235 and 5-FU showed synergistic inhibitory effects on proliferation, migration, and invasion and synergistic stimulating effects on apoptosis of MKN-45 cells. In vivo, NVP-BEZ235 and 5-FU synergistically inhibited the growth and induced apoptosis of MKN-45 xenografts. Mechanistically, NVP-BEZ235 inhibited PI3K/Akt/mTOR signaling; decreased the levels of Bcl-2, MMP9, and VEGF; but increased the levels of Bax and cleaved caspase-3 in MKN-45 xenografts. Conclusion: NVP-BEZ235 enhances the antitumor efficacy of 5-FU. Therefore, NVP-BEZ235 is a promising agent to enhance chemotherapy for gastric cancer. PMID- 30275719 TI - The quest for the identity of Orthoceratiumlacustre (Scopoli, 1763) reveals centuries of misidentifications (Diptera, Dolichopodidae). AB - Recently, a species of Orthoceratium was collected in Greece that differs morphologically from the European species commonly presumed to be Orthoceratiumlacustre (Scopoli, 1763). Verification of the identity of the Greek species through comparison with 460 specimens of Orthoceratium from 17 West Palaearctic and one Afrotropical country, and examination of existing type material, revealed that the species recognized as O.lacustre in northwestern Europe for over 250 years is actually O.sabulosum (Becker, 1907), the other known species in the genus, which was originally described from Tunisia. Although the types of O.lacustre have been lost, a comparison of the distribution ranges of both species in Europe provided evidence that the species collected in Greece is conspecific with O.lacustre. Both species have distinct distributions in the West Palaearctic, with O.lacustre largely restricted to the northern border of the Mediterranean basin, and O.sabulosum more widespread, occurring in northwestern Europe, the western, southern, and eastern Mediterranean, the Middle East, and the Afrotropical Region (Tanzania). Both species are redescribed and fully illustrated, a neotype is designated for O.lacustre and a lectotype for O.sabulosum, and a key to males and females is provided. The misidentifications that lasted for over two centuries are explained by the omission by previous authors to study the type specimens, and inaccuracies in species descriptions and keys. PMID- 30275720 TI - Description of a Cretaceous amber fossil putatively of the tribe Coprophilini (Coleoptera, Staphylinidae, Oxytelinae). AB - An unusual and well-preserved fossil staphylinid is described and figured from a single specimen in Upper Cretaceous Burmese amber. Gollandiaplanata gen. et sp. n. is tentatively placed in the extant oxyteline tribe Coprophilini, although it lacks a few characteristic features of present-day members of the group, likely indicating it to be either a stem group of the tribe or prove to be distinct pending future discoveries. The discovery of this genus suggests that early oxytelines were more morphologically diverse during the Cretaceous and their evolutionary history was more complicated than previously documented. Tribal placement as regards fossil oxyteline taxa is discussed. PMID- 30275721 TI - The genus Mercuria Boeters, 1971 in Morocco: first molecular phylogeny of the genus and description of two new species (Caenogastropoda, Truncatelloidea, Hydrobiidae). AB - The western Palearctic freshwater snail genus Mercuria (Caenogastropoda: Hydrobiidae) comprises 26 species primarily distributed in lowland localities of Western Europe and North Africa. Although this genus in North Africa has received considerable attention in terms of species discoveries through morphological descriptions, its distribution and phylogenetic patterns remain unknown. Based on morphological and mitochondrial DNA (mtCOI) evidence, this study examines the three Mercuria species (M.bakeri, M.tingitana, and M.targouasensis) from Morocco identified so far. Besides expanding on information regarding the anatomy of these species, two new species (M.midarensis sp. n. and M.tensiftensis sp. n.) are described for this region and phylogenetic relationships inferred between these species and the European M.emiliana and M.similis. All Moroccan and European species were recovered as independent entities according to these phylogenetic inferences (uncorrected p-distances 2.8-8.5%) and DNA barcode data. Moroccan Mercuria species clustered with M.emiliana from Spain, although basal relationships within this clade were not well supported. Given that factors such as the season when specimens are collected, habitat type, and parasites could be responsible for the remarkable intraspecific variation observed in shell and penis morphology, it is proposed that the most efficient approach to delimit and identify Mercuria species is to combine morphological descriptions with genetic data. PMID- 30275722 TI - Four new species of Lesticus (Carabidae, Pterostichinae) from China and supplementary comments on the genus. AB - The genus Lesticus in China was studied, with descriptions of four new species: L.auripennis sp. n. (Guangdong: Nanling, 24.93 degrees N, 112.09 degrees E); L.bii sp. n. (Xizang: Medog, 29.32 degrees N, 95.34 degrees E); L.xiaodongi sp. n. (Yunnan: Yingjiang, 24.71 degrees N, 97.58 degrees E); and L.violaceous sp. n. (Yunnan: Yingjiang, 24.71 degrees N, 97.58 degrees E). One new synonym is proposed: L.dubius Dubault, Lassalle & Roux, is a junior synonym of L.solidus Roux & Shi. An improved key and a catalogue accommodating all known Chinese Lesticus species are provided. Species relationships and the evolution of endophallic and other characters are preliminarily discussed.

AB - Epocillapakhtunkhwa Ali & Maddison, sp. n. and Stenaelurillusmardanicus Ali & Maddison, sp. n. are described from Khyber Pakhtunkhwa Province, Pakistan. Noted for the first time is the presence in Epocilla of a small bump just anterior to the fovea of the carapace, of unknown functional significance, otherwise known in the unrelated Opisthoncus L.

PMID- 30275724 TI - Two new species of Hydromedusae from Queensland, Australia (Hydrozoa, Leptothecata). AB - Two new species of small hydromedusae were found during routine monitoring in coastal waters of eastern Australia and are here described. The first, Melicertissaantrichardsoni Uribe-Palomino & Gershwin, sp. n., from Moreton Bay, Queensland, is placed in its genus because of its possession of both cordyli and eight-fold symmetry. It differs from its congeners in two conspicuous features: firstly, having small, oval split gonads located adjacent to the base of the stomach, and secondly, in its extremely small size at maturity (2 mm bell diameter, compared to the next smallest species at 7 mm). Moreover, it possesses a unique combination of other characters. This species appears to be endemic to Moreton Bay. The second new species, Paraloveniayongalensis Gershwin & Uribe Palomino, sp. n., from the Great Barrier Reef, Queensland, is placed in its genus because of its two opposite normal tentacles and two opposite marginal clusters of cirri. It differs from its congeners primarily in a more rounded body than the others; the shape, length, and position of its short spindle-shaped, distal gonads; possession of subumbrellar nematocyst clusters; and possession of statocysts. These discoveries bring the total number of Melicertissa species to eight and the total number of Paralovenia species to three. The discovery of these two micromedusae underscores the need for further examination of the often ignored minute and/or gelatinous fauna. PMID- 30275725 TI - On the molecular and morphological evolution of continental and insular Cryptorchestia species, with an additional description of C.garbinii (Talitridae). AB - Semi-terrestrial talitrid amphipods of the genus Cryptorchestia (sensu Lowry and Fanini 2013) associated with freshwater-soaked leaf litter were known to occur in inland lakes of Turkey and at the shores of the Black Sea. Before 2013 they had been reported as Orchestiacavimana and later as Cryptorchestiacavimana. In our phylogenetic tree, inferred from a mitochondrial and nuclear gene dataset (cytochrome oxidase I (COI), and histone H3 (H3), respectively), we show that these Turkish populations belong to Cryptochestiagarbinii, a common and widespread continental species, which is closely related to C.cavimana (endemic to Cyprus) and C.ruffoi (endemic to Rhodes). For the Turkish and European populations of C.garbinii, we found low levels of both genetic differentiation and morphological variation, and an age-related size variability (increasing at each moult) of the small lobe in the male gnathopod I merus, the main taxonomically diagnostic character for Cryptorchestia. A mainland (C.garbinii) versus insular isolation and in situ speciation (C.cavimana, and C.ruffoi) in the two east Mediterranean islands of Cyprus and Rhodes is discussed in relation to terrestrial Cryptorchestia species endemic to North East Atlantic volcanic islands (Azores, Canary Islands, and Madeira). The incorporation of five Mediterranean and Atlantic Orchestia species in the Bayesian analysis of the two genes (COI, and H3) indicated that both genera Orchestia and Cryptorchestia are not monophyletic.

PMID- 30275727 TI - Revision of the Polynemadikobraz species-group with description of a remarkable new species from South Africa (Hymenoptera, Chalcidoidea, Mymaridae). AB - A new Afrotropical species of Polynema Haliday, 1833 (Hymenoptera: Mymaridae), Polynema (Polynema) sagittaria van Noort & Triapitsyn, sp. n., is described and illustrated based on specimens collected in the Cape Floral region in south western South Africa. This species is morphologically closely related to the recently described Polynema (Polynema) dikobraz Triapitsyn, 2017 from Madagascar, both species possessing enlarged spine-like microtrichia on the fore wing disc that are unique among all the known world fairyflies. This new species belongs to the informal dikobraz species-group of the nominate subgenus of Polynema, which previously was only known from Madagascar. In addition, P.sagittaria has the ovipositor extending ventrally under the mesosoma to well in front of the head, in a bow-like curve, and housed in a narrow, anterior elongation of the metasoma, the basal sac. Occurrence and possible significance of such a bizarre ovipositor in other Mymaridae is discussed. All images and online keys are available on www.waspweb.org.

PMID- 30275730 TI - Morphological and molecular (28S rRNA) data of monogeneans (Platyhelminthes) infecting the gill lamellae of marine fishes in the Campeche Bank, southwest Gulf of Mexico. AB - During the examination of 913 fish specimens belonging to four families in the Campeche Bank (Gulf of Mexico), 23 gill ectoparasitic monogenean species were found, which belong to three families: Dactylogyridae, Microcotylidae and Diclidophoridae. The species Euryhaliotremaamydrum, E.carbuncularium, E.dunlapae, E.fajeravilae, E.fastigatum, E.longibaculum, E.paracanthi, E.tubocirrus, Haliotrematoidescornigerum, H.gracilihamus, H.heteracantha, H.longihamus, H.magnigastrohamus, H.striatohamus, Hamatopedunculariabagre, Neotetraonchusbravohollisae, and N.felis (all Dactylogyridae) were found on the hosts Lutjanussynagris, L.griseus, Ariopsisfelis, Bagremarinus, Archosargusrhomboidalis, and Haemulonplumieri. Additionally, Microcotylearchosargi, Microcotyle sp., and Microcotyloidesincisa (all Microcotylidae) were found on L.griseus and A.rhomboidalis; finally, Choricotyle sp. 1, Choricotyle sp. 2, and Choricotyle sp. 3 (all Diclidophoridae) were found on H.plumieri. The prevalence, abundance, mean intensity of infection, and supplementary taxonomic revisions for all monogeneans found are provided. Partial sequences of the 28S rRNA gene were also obtained for monogeneans of ariid, sparid, and haemulid host fishes to explore their systematic position within the Monogenea. New locality and host records for some previously described species of Euryhaliotrema, Hamatopeduncularia, Microcotyle, and Choricotyle from lutjanid, ariid, sparid, and haemulid hosts were reported. The present study adds evidence supporting the interoceanic occurrence of the same monogenean species (on lutjanids) on the west-east Atlantic and Pacific Oceans (= amphiamerican species). As previously suggested, there are at least, two possibilities to explain that parasite distribution: differentiation of morphological features in these monogeneans have resulted in only slight to insignificant morphological changes developing over the extended period of 3.2 mya (when the Isthmus of Panama was closing) and/or speciation is only evident at molecular level. PMID- 30275731 TI - A new black nightshade (Morelloid clade, Solanum, Solanaceae) from the caatinga biome of north-eastern Brazil with a key to Brazilian morelloids. AB - Solanumcaatingae sp. nov. is described from the arid caatinga biome of north eastern Brazil. It is known from only a few specimens, but these were found amongst the many sheets of the widespread circumtropical weed S.americanum Mill.; it is possible that more will be found once its distinct nature has been recognised. It differs from S.americanum and all other herbaceous black nightshades known in Brazil, in its combination of glandular pubescence and shiny black fruit with small spreading sepals. The description of S.caatingae brings the number of morelloid solanums in Brazil to seven and a key is provided for their identification. PMID- 30275732 TI - Evidence from checklists for a Holarctic (circumboreal) kingdom of diatoms. AB - Published checklists of freshwater diatoms that represent the American Northwest, Laurentian Great Lakes, Germany and the South Polar Region were compared systematically and the numbers of taxa shared by two or more of these regions were noted. There is a higher level of floristic correspondence between the American Northwest and Germany (71%) and between the American Northwest and the Laurentian Great Lakes (64%) than between the American Northwest and the South Polar Region (45%). These findings support a Holarctic Kingdom of diatoms that is parallel to the Holarctic Kingdom of flowering plants. Mountains and coastal areas and/or inland waters of high salinity may explain why the American Northwest and Germany have more taxa in common than the American Northwest and the Laurentian Great Lakes. Common riverine diatom taxa in the American Northwest are similar to those reported from nationwide monitoring stations. The number of truly cosmopolitan species - those found on all continents - is probably less than 300. The terms "cosmopolitan", "endemic" and "native" are often misused when applied to diatoms and the first two terms always need to be qualified.

AB - A total evidence phylogeny for Pontederiaceae is herein presented based on new morphological and previously published molecular data. Our results led us to re circumscribe Pontederia to include Monochoria, Pontederia s.s. and the polyphyletic Eichhornia. We provide the needed ten new combinations and 16 typifications, arrange a total of 25 accepted species (six representing re established names) in 5 new subgenera. Furthermore, we provide an identification key for the two genera accepted by us in Pontederiaceae, an identification key to the subgenera, identification keys to the species of each subgenus and commentaries on Pontederia s.l., as well as for each subgenus and each species. PMID- 30275734 TI - Nomenclatural review of Acalypha (Euphorbiaceae) of the Western Indian Ocean Region (Madagascar, the Comoros Archipelago, the Mascarene Islands and the Seychelles Archipelago). AB - This work presents a critical nomenclatural review of the Acalypha species of the Western Indian Ocean Region (Madagascar, the Comoros Archipelago, the Mascarene Islands and the Seychelles Archipelago). This is the first treatment of Acalypha of Madagascar since Leandri's monograph in 1942. A total of 151 scientific names related to Acalypha from this region are treated. We recognise 35 species (28 native and seven introduced), treat 93 names as synonyms (28 of them for the first time) and identify three as doubtful or excluded names. We designate lectotypes for 41 names, make two new combinations and propose one new name. PMID- 30275735 TI - Taxonomic status of Populuswulianensis and P.ningshanica (Salicaceae). AB - Species delimitation in the genus Populus is particularly challenging due to high levels of intraspecific polymorphism as well as frequent interspecific hybridisation and introgression. In this study, we aimed to examine the taxonomic status of Populusningshanica and P.wulianensis using an integrative taxonomy that considers multiple operational criteria. We carried out morphometric analyses of leaf traits and genetic examinations (including sequence variations at five barcoding DNAs and polymorphisms at 14 nuclear microsatellite SSR primers) at the population level between them and two closely related species P.adenopoda and P.davidiana. Results suggest that P.wulianensis belongs to the polymorphic species, P.adenopoda and should be considered as a synonym of the latter. P.ningshanica may have arisen as a result on the hybridisation between P.adenopoda and P.davidiana and therefore should be treated as P.*ningshanica. This study highlights the importance of the integrated evidence in taxonomic decisions of the disputed species. PMID- 30275736 TI - Togo National Herbarium database. AB - This article describes the herbarium database of the University of Lome. The database provides a good representation of the current knowledge of the flora of Togo. The herbarium of University of Lome, known also as Herbarium togoense is the national herbarium and is registered in Index Herbariorum with the abbreviation TOGO. It contains 15,000 specimens of vascular plants coming mostly from all Togo's ecofloristic regions. Less than one percent of the specimens are from neighbouring countries such as Ghana, Benin and Burkina Faso. Collecting site details are specified in more that 97% of the sheet labels, but only about 50% contain geographic coordinates. Besides being a research resource, the herbarium constitutes an educational collection. The dataset described in this paper is registered with GBIF and accessible at https://www.gbif.org/dataset/b05dd467-aaf8-4c67-843c-27f049057b78. It was developed with the RIHA software (Reseau Informatique des Herbiers d'Afrique). The RIHA system (Chevillotte and Florence 2006, Radji et al. 2009) allows the capture of label data and associated information such as synonyms, vernacular names, taxonomic hierarchy and references.

PMID- 30275738 TI - A series of unfortunate events: the forgotten botanist and the misattribution of a type collection. AB - In 1777, Spain sent The Royal Expedition to Peru and Chile, commonly referred to as the "Ruiz and Pavon Expedition", to document the flora of this richly diverse part of its colonies. The Expedition was active in the New World for 38 years and was led by Hipolito Ruiz and Jose Pavon, who collected in Peru and Chile for the first 11 years before returning to Spain to work on publication of the Flora Peruviana, et Chilensis. Work on the ground for the reminder of the project in Peru and later Ecuador, was continued by Juan Tafalla and Juan Manzanilla. With few exceptions, all collections from the Expedition including types, have conventionally been attributed to Ruiz and Pavon despite the fact that Tafalla and Manzanilla were responsible for a large part of the collections. The purpose of this note is to bring to light the important but often overlooked figure of Juan Tafalla, to highlight his accomplishments as a collector and to increase precision in botanical nomenclature by giving him due credit by correctly attributing collections.

AB - Members of the mushroom genus Amanita usually can easily be identified to the genus in the field, however, species circumscription and identification are often problematic. Several names have been misapplied and cryptic species exist. Here, we formally describe and validate two new species of Amanitasect.Vaginatae from eastern North America that were recognised under the umbrella European names A.ceciliae by past authors: Amanitarhacopus sp. nov. and Amanitavariicolor sp. nov. PMID- 30275740 TI - Additions to tribe Chromosereae (Basidiomycota, Hygrophoraceae) from China, including Sinohygrocybe gen. nov. and a first report of Gloioxanthomycesnitidus. AB - Sinohygrocybe gen. nov., typified by S.tomentosipes sp. nov., is described upon morphological and molecular evidence. The new genus is characterised by its sinuate to subdecurrent or short deccurent, usually furcate and interveined and relatively distant lamellae, dry and whitish tomentose stipe, thin-walled ellipsoid to oviod, non-constricted basidiospores and particularly elongated basidia and a ratio of basidiospore to basidium length of >5 to 8; it is close to genera Chromosera and Gloioxanthomyces of the tribe Chromosereae, but morphologically differs from Chromosera in less umbilicate basidiomata, tomentose stipe and usually longer basidia and differs from Gloioxanthomyces in more robust basidioma and less glutinous pileus and/or stipe surface. Phylogenetic analyses, with ITS-LSU-RPB2 data, also indicate that Sinohygrocybe forms a very distinct and independent clade at the generic level. In addition, a Chinese new record G.nitidus is described here. PMID- 30275741 TI - A discussion on the genus Fomitiporella (Hymenochaetaceae, Hymenochaetales) and first record of F.americana from southern South America. AB - Fomitiporella has traditionally been delimited based on the gross morphology of the basidiomes, hyphal structure and basdiospores. Recently, phylogenetic studies supported the incorporation of an extensive number of species within the genus. Although most of its species are nested in the 'Phellinotus clade' (Hymenochaetaceae, Basidiomycota), genera such as Arambarria, Inocutis and Phellinotus were not included in previous analysis. To further our understanding of the genus, new sequences from 28S and ITS nuc rDNA genes were jointly analysed with a large selection of taxa in the 'Phellinotus clade', also with re examination of morphological and ecological data. Results showed several lineages in what has hitherto been considered to represent Fomitiporella, indicating that the genus is paraphyletic as presently circumscribed. There is a well-supported Fomitiporella core group that includes the type species and nine other monophyletic lineages with high support, of which those representing Arambarria, Inocutis and Phellinotus are distinct from the Fomitiporella core group by macro and micromorphological traits and/or biogeographic distribution. Fomitiporellaamericana, a species described from SE USA, was found in the Patagonian forests of southern Argentina and Chile; it is the taxon responsible for the white heart-rot found on standing Austrocedruschilensis and one of the taxa decaying wooden tiles of historic churches in Chiloe Is., Chile.

AB - Mangroves are relatively unexplored habitats and have been shown to harbour a number of novel species of fungi. In this study, samples of microfungi were collected from symptomatic branches, stem and leaves of the mangrove species Xylocarpusgranatum, X.moluccensis and Lumnitzeraracemosa and examined morphologically. The phylogeny recovered supports our morphological data to introduce three new species, Cytosporalumnitzericola, C.thailandica and C.xylocarpi. In addition, a combined multi-gene DNA sequence dataset (ITS, LSU, ACT and RPB2) was analysed to investigate phylogenetic relationships of isolates and help in a more reliable species identification. PMID- 30275743 TI - Multilocus phylogeny reveals taxonomic misidentification of the Schizoporaparadoxa (KUC8140) representative genome. AB - Schizoporaparadoxa, current name Xylodonparadoxus, is a white-rot fungus with certain useful biotechnological properties. The representative genome of Schizoporaparadoxa strain KUC8140 was published in 2015 as part of the 1000 Fungal Genomes Project. Multilocus phylogenetic analyses, based on three nuclear regions (ITS, LSU and rpb2), confirmed a misidentification of S.paradoxa strain KUC8140 which should be identified as Xylodonovisporus. This wrong identification explains the unexpected geographical distribution of S.paradoxa, since this species has a European distribution, whereas the strain KUC8140 was recorded from Korea, Eastern Asia. PMID- 30275745 TI - Evaluation of a Program of Clean Intermittent Catheterization for Underactive Bladder After Radical Hysterectomy. AB - Background: Dysfunction of the lower urinary tract is the most common complication of radical hysterectomy (RH). However, there are no established treatment protocols for postoperative underactive bladder (PUB). We developed our own new program for the treatment of underactive bladder (UB) after RH and evaluated it retrospectively. Methods: In this program, there are five steps for patients to follow according to their urinary condition. The first step is the administration of urapidil 30 mg, voiding six times at a predetermined time each day, and clean intermittent catheterization (CIC) after each voiding. As the patient's condition improves, the number of CICs is reduced, and the medication is stopped. The last step includes voiding six times at a predetermined time each day. When the volume of residual urine (RU) is less than 100 mL, patients move on to the next step. When the volume of RU exceeds 100 mL, patients return to the previous step. Results: Of the 75 patients who visited our department, 41 were eligible for this program. Twenty-two patients visited our department because of urinary retention (UR), and 19 patients were admitted because of increased RU. The mean RU volume was 276.3 mL (range, 150-550 mL). After completing the program, 39 (95.1%) patients no longer required CIC. The mean time to withdrawal of CIC was 25.1 weeks (range, 1-72 weeks). Thirty-six patients no longer required medical treatment, including urapidil, for PUB. Of the 5 patients who had persistent PUB after treatment, 2 patients continued CIC and urapidil, and three patients continued urapidil alone. Conclusion: The present results demonstrate that the program of CIC in combination with urapidil is effective for the management of PUB after RH. PMID- 30275744 TI - Role of Neuroimaging on Differentiation of Parkinson's Disease and Its Related Diseases. AB - An accurate diagnosis of Parkinson's disease (PD) is a prerequisite for therapeutic management. In spite of recent advances in the diagnosis of parkinsonian disorders, PD is misdiagnosed in between 6 and 25% of patients, even in specialized movement disorder centers. Although the gold standard for the diagnosis of PD is a neuropathological assessment, neuroimaging has been playing an important role in the differential diagnosis of PD and is used for clinical diagnostic criteria. In clinical practice, differential diagnoses of PD include atypical parkinsonian syndromes such as dementia with Lewy bodies, multiple system atrophy, progressive supranuclear palsy, corticobasal degeneration, caused by a striatal dopamine deficiency following nigrostrial degeneration. PD may also be mimicked by syndromes not associated with a striatal dopamine deficiency such as essential tremor, drug-induced parkinsonism, and vascular parkinsonism. Moreover, difficulties are associated with the clinical differentiation of patients with parkinsonism from those with Alzheimer's disease. In this review, we summarize the typical imaging findings of PD and its related diseases described above using morphological imaging modalities (conventional MR imaging and neuromelanin MR imaging) and functional imaging modalities (99mTc-ethyl cysteinate dimer perfusion single photon emission computed tomography, 123I metaiodobenzylguanidine myocardial scintigraphy, and 123I-FP-CIT dopamine transporter single photon emission computed tomography) that are clinically available in most hospitals. We also attempt to provide a diagnostic approach for the differential diagnosis of PD and its related diseases in clinical practice. PMID- 30275746 TI - The Acquisition of a New Self-image in Patients with Type 1 Diabetes: A Qualitative Study. AB - Background: In this study, we aim to highlight the transformation of self-image in patients with type 1 diabetes after diagnosis. Our objective in examining the self-image of these patients is to provide practical insights for nursing, as well as a basic reference for understanding patients. Methods: The participants were 15 patients (2 men and 13 women) over 20 years of age who visited an outpatient setting to treat type 1 diabetes and had no serious complications, and who agreed to participate in the study. Semi-structured interviews were conducted 1-2 times, with a duration of 60-75 minutes per person, from February 2016 to March 2017. We drew on Krippendorff's (1999) content analysis to carry out our analysis. Results: We identified a total of 107 codes. The self-image of patients with type 1 diabetes was categorized into 8 subcategories and 4 categories. The 4 categories were 'the wavering of a self-image that is distinct from the past,' 'loss of former self-image,' 'discovery of a new self-image,' and 'developing a new self-image.' Ultimately, we were able to extract a fifth core category, 'acquisition of a new self-image.' Conclusion: The self-image of patients with type 1 diabetes transformed from a negative to a positive one; ultimately, patients acquired a new self-image that was congruent with their ideal self image. Our results showed that the new self-image that patients acquired through various experiences influenced motivation for treatment and continuation of self care. When caring for patients with type 1 diabetes, it is crucial for healthcare professionals be aware of the meaning that patients derive from their disease and related difficulties, as well as to provide care while considering patients' self image. PMID- 30275747 TI - Qualitative Analysis of the Psychosocial Adaptation Process in Children with Chronic Kidney Disease: Toward Effective Support During Transition from Childhood to Adulthood. AB - Background: Pediatric chronic renal disease only shows abnormal values in a urinalysis in the initial stage, and subjective signs and symptoms are rare. If adolescents with chronic renal disease face a disease crisis combined with the usual developmental crisis, this may cause psychosocial maladaptation. We analyzed psychosocial adaptation in Japanese children with chronic renal disease in order to identify factors influencing healthy adaptation. Methods: Ten children and adult patients with chronic kidney disease attending Tottori University Hospital, Japan in 2016 participated in a semi-structured interview (a modified version of the grounded theory approach) comprising questions about episodes since disease onset and thoughts/feelings at onset. Results: Twenty-four concepts extracted from the data were sorted into 5 categories. These concepts and categories were expanded on an orthogonal axis with time and self-esteem in order to establish an adaptation model for children with chronic kidney disease. Category names are as follows. (Cat. 1: Emotional impact on being informed of disease, Cat. 2: Social challenges of treatment and resulting identity diffusion, Cat. 3: Emotional conflict on school return, Cat. 4: Resilience and related factors, Cat. 5: Re-establishment of identity). Conclusion: Since pediatric chronic renal disease has few manifestations, it is difficult for patients to accept. Children facing a chronic disease crisis plus adolescent developmental crisis may show identity diffusion. In order for children to re-establish their identity and adapt to society, factors supporting resilience are important. Key factors include school life, interactions with friends, counseling by adult mentors and family acceptance. Healthcare professionals need to provide age appropriate information on renal disease and support patients. PMID- 30275748 TI - Therapeutic Value of Lymph Node Dissection Along the Superior Mesenteric Vein and the Posterior Surface of the Pancreatic Head in Gastric Cancer Located in the Lower Third of the Stomach. AB - Background: Therapeutic value of lymph node dissection along the superior mesenteric vein (14v) and the posterior surface of the pancreatic head (13) remains unclear in gastric cancer patients. Methods: We reviewed 355 patients with advanced gastric cancer in the lower third of the stomach who had undergone gastrectomy at our hospital. Results: The frequency of lymph node (LN) metastasis was 10.2% and 7.4% in stations 13 and 14v, respectively. The frequency of station 13 metastasis was 26.8% for T3/T4 tumors with group 2 LNs metastasis and 1.4% for all other tumors. The frequency of station 14v metastasis was 22.2% for T3/T4 tumors with group 2 LNs metastasis and 1.8% for all other tumors. The therapeutic values for dissecting LN stations 13 and 14v were 1.9 and 0.9, respectively, similar to the therapeutic value for group 2 LN dissection. Conclusion: Because metastasis to stations 13 and 14v occurs frequently in patients with T3/T4 gastric cancer located in the lower third of the stomach who also have metastasis to group 2 LNs, stations 13 and 14v should be dissected in these patients.

AB - The standard procedure for remnant gastric cancer after esophago-proximal gastrectomy is total resection of the remnant stomach considering blood supply. However, sometimes surgery may be too invasive due to severe adhesion in the thoracic and mediastinal cavity. The blood supply to the remnant stomach depends on the right gastroepiploic artery and the right gastric artery. Therefore, preservation of the proximal region of the remnant stomach is thought to be anatomically impossible. We report a case of remnant gastric cancer that developed more than 12 years after lower thoracic esophagectomy plus proximal gastrectomy for Siewert Type I squamous cell carcinoma. We used intra-operative indocyanine green (ICG) venous-injection to evaluate blood flow and distal gastrectomy of the remnant stomach was performed by preserving the proximal stomach in the thoracic cavity through an abdominal approach. There were no complications of the remnant stomach or the anastomosis to the jejunum after surgery. In this case, we focused on the blood supply by collateral circulation through the anastomotic line from the remnant esophagus. After confirming blood supply with intra-operative evaluation using ICG fluorescence, less-invasive distal gastrectomy was successfully performed. As the intra-operative ICG-based evaluation for blood supply is a simple and safe method, it might be useful for determining the resection margin of various organs and be effective for the introduction of less invasive surgery. Here, we report a case and a review of the literature. PMID- 30275749 TI - Portal Vein Stenting for Portal Vein Stenosis After Pancreatoduodenectomy: A Case Report. AB - Portal vein stenosis, which results in serious clinical conditions such as gastrointestinal variceal bleeding and liver failure, is caused by hepatobiliary pancreatic cancer or major postoperative complications after hepatobiliary pancreatic surgery. In recent years, portal vein stenting under interventional radiology has been applied as a more useful treatment method for portal vein stenosis than invasive surgery. We herein report the successful use of a vascular stent for portal vein stenosis after pancreatoduodenectomy. A 66-year-old man with distal cholangiocarcinoma underwent subtotal stomach-preserving pancreatoduodenectomy with resection of the portal vein because of direct invasion to the main portal vein at our hospital. The portal vein was reconstructed without a venous graft. He developed jejunal bleeding near the pancreatojejunostomy on postoperative day (POD) 2. Although embolization of the responsible vessel achieved hemostasis, an intraoperatively inserted drainage tube was needed for a long period of time postoperatively because the embolized afferent jejunum was perforated. He was discharged on POD 39 after removal of the drainage tube. On POD 282, he was readmitted with melena and severe fatigue. Computed tomography revealed an obstruction of the reconstructed portal vein and varices at the hepaticojejunostomy site. We diagnosed variceal bleeding and performed percutaneous transhepatic stenting in the obstructed portal vein. The patient was discharged in good clinical condition on day 15 after stenting. In conclusion, portal vein stenting is a useful and less invasive therapy for portal vein stenosis. PMID- 30275752 TI - High Levels of Serum Adipocyte Fatty Acid-binding Protein Predict Cardiovascular Events in Coronary Artery Disease Patients. AB - Background: Adipocyte fatty acid-binding protein (A-FABP) is a cardiometabolic predictor of cardiovascular (CV) disease in humans. We evaluated the association between serum A-FABP levels and future CV events in patients with coronary artery disease (CAD). Methods: A total of 106 CAD patients were enrolled in this study between January and December 2012 and were followed-up until June 30, 2017. The primary endpoint was the incidence of major adverse CV events. Results: During a median follow-up period of 53 months, 44 CV events occurred. Patients with CV events presented higher systolic blood pressure (p = 0.020), total serum cholesterol (p = 0.047), and serum A-FABP levels (p < 0.001) compared with patients without CV events. Kaplan-Meier analysis showed that the cumulative incidence of CV events in the high A-FABP group (median A-FABP concentration of >17.63 ng/mL) was higher than that in the low A-FABP group (log-rank p < 0.001). Multivariate Cox analysis showed that triglycerides (hazard ratio (HR): 1.008, 95% confidence interval (CI): 1.001-1.016, p = 0.026) and serum A-FABP levels (HR: 1.027, 95% CI: 1.009-1.047, p = 0.004) were independently associated with CV events. Conclusion: Serum A-FABP level is a biomarker for future CV events in patients with CAD. Further prospective studies are needed to confirm the mechanisms underlying this association. PMID- 30275751 TI - A New Isolation Method of Human Lacrimal Canaliculus Epithelial Stem Cells by Maintaining Close Association with Their Niche Cells. AB - Purpose: To investigate whether lacrimal canaliculus epithelial stem cells (LCESC) could be isolated and expanded in vitro. Methods: The lacrimal canaliculus epithelium of 6 patients with limbal stem cell deficiency (LSCD) caused by alkali burn or Stevens Johnson Syndrome were examined by lacrimal endoscope. Cadaveric eyelids were fixed and prepared for cross section and stained with HE and antibodies against PCK, Vim, p63alpha, SCF and c-Kit. Canaliculus tissue was separated under an operating microscope using a lacrimal probe as an indicator and digested with collagenase A. The clusters of epithelial cells with closely associated stroma were further digested with Trypsin/EDTA to obtain single cells for culture on Matrigel-coated plastic plates in MESCM media. The expression of SCF, c-Kit and p63alpha was determined by immunostaining. The colony-forming efficiency on 3T3 feeder layers was also measured by calculating the percentage of the clone number divided by the total number cells seeded. Results: The epithelial layers of five out of six inferior lacrimal canaliculi and all the six superior lacrimal canaliculi were visually normal in appearance. Five to fifteen layers of the epithelium in the human lacrimal canaliculi were present with a small, tightly compacted basal layer of cells expressing PCK, p63alpha, SCF and c-Kit. LCESC were isolated by collagenase A and obtained clonal growth in MESCM. The colony-forming efficiency of LCESC holoclones on a 3T3 feeder layer was 3.2%, compared to 1.9% for those of limbal stem cells (LSC). Conclusions: Herein, we first report that LCESCs can be isolated and have stem cell characteristics, similar to those of LSCs. Such a discovery raises a promising substrate resource of stem cells for LSC reconstruction in LSCD patients. PMID- 30275753 TI - Randomized, controlled clinical pilot study of venous leg ulcers treated with using two types of shockwave therapy. AB - Background. Venous leg ulcers are difficult to heal wounds. The basis of their physiotherapeutic treatment is compression therapy. However, for many years, the search for additional or other methods to supplement the treatment of venous ulcers, which would shorten the duration of treatment, is underway. One of such methods is the shockwave therapy. Methods. The purpose of our study was to compare radial shockwave therapy (R-ESWT) with focused shockwave therapy (F-ESWT) in venous leg ulcers treatment. Patients were randomly assigned to tree groups. In the first group the radial shockwave therapy (0.17mJ/mm2, 100 impulses/cm2, 5 Hz), in the second group the focused shockwave therapy (0.173mJ/mm2, 100 impulses/cm2, 5 Hz) was used and in third group standard care was used. Patients in shockwave therapy groups were given 6 treatments at five-day intervals. Total area, circumference, Gilman index, maximum length and maximum width of ulcers were measured. The patients from the third group wet gauze dressing with saline and gently compressing elastic bandages were used (standard wound care SWC). Results. Analysis of the results shows that a complete cure of ulcers was achieved in 35% of patients who were treated with radial shockwave, 26% of patients with focused shockwave used. There is statistically significant difference between the standard care and radial shockwave therapy as well as between the standard care and focused shockwave therapy. There is no statistically significant difference between the use of radial and focused shockwave in the treatment of venous leg ulcers (p> 0.05). Conclusion. There is no statistically significant difference between the use of radial and focused shockwave in the treatment of venous leg ulcers. Treatment of venous leg ulcers with shockwaves is more effective than the standard wound care. PMID- 30275754 TI - Cannabinoids: from pot to lab. AB - Cannabis is becoming increasingly present in our society. In recent years, the line between the natural (cannabis) and the synthetic (synthetic cannabinoids), the recreational (cannabis) and the medical (pharmaceutical cannabinoids and medical cannabis) has been crossed. In this paper we review some of the novel aspects of cannabis and cannabinoids in relation to their legal situation, changes in their composition and forms of cannabis use, the concept of medical cannabis, and synthetic cannabinoids as new psychoactive substances (NPS). We have also analyzed serious adverse reactions and intoxications associated with the use of synthetic cannabinoids, as well as the latest developments in the research of pharmaceutical cannabinoids. PMID- 30275755 TI - Eicosapentaenoic acid reduces indoleamine 2,3-dioxygenase 1 expression in tumor cells. AB - Marine plants and animals have omega-3 fatty acids including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EPA is required for biological processes, but humans are unable to synthesize them and must be obtained from dietary sources. EPA has been used as an antitumor agent but the molecular mechanisms for the regulation of tumor microenvironment immunity by EPA are still unknown. The indoleamine 2,3-dioxygenase 1 (IDO) catalyzes conversion of tryptophan to kynurenine to induce immune evasion in tumor microenvironment. In this study, EPA inhibited the expression of IDO via downregulation of protein kinase B (Akt)/mammalian targets of rapamycin (mTOR) signaling pathway in tumor cells. Meanwhile, a significant decrease in kynurenine levels and increase in T cell survival were observed after tumor cells treated with EPA. The results demonstrated that EPA can activate host antitumor immunity by inhibiting tumor IDO expression. Therefore, our finding suggests that EPA can be enormous potential for cancer immunotherapy. PMID- 30275756 TI - The Role of YB1 in Renal Cell Carcinoma Cell Adhesion. AB - Background: Y-box binding protein 1 (YB1) is a multifunctional protein involved in many processes related to cancer progression and metastasis. Methods: In this study, we constructed YB1 knockdown stable renal cell carcinoma (RCC) cell line 786-0. The gene expression profile of 786-0 was performed by DNA microarray analysis to identify genes that were regulated by YB1. Real-time PCR and western blotting were used to test the genes and proteins expression. Transforming growth factor-beta (TGF-beta) activity was detected by dual-luciferase reporter assay. Cell adhesion assay was used to determine RCC cell adhesion ability. Results: Pathway analysis revealed that YB1 knockdown influenced cell adhesion molecules (CAMs). We further verified four genes (CLDN4, NRXN3, ITGB8, and VCAN) related to CAMs by real-time PCR, and confirmed that YB1 regulated the expression of ITGB8 in RCC. Functional assays demonstrated that knockdown of YB1 significantly inhibited the cell adhesion of 786-0 cells in vitro. In addition, YB1 affected TGF-beta activation. Conclusion: Our study demonstrated that YB1 modulated the adhesion ability of renal cell carcinoma cells by regulating ITGB8 and TGF-beta. PMID- 30275757 TI - Significant association of long non-coding RNAs HOTAIR genetic polymorphisms with cancer recurrence and patient survival in patients with uterine cervical cancer. AB - Up to date, no study explores the relationship of single nucleotide polymorphisms (SNPs) of long non-coding RNAs HOTAIR (lncRNAs HOTAIR) with cancer recurrence and patient survival in uterine cervical cancer for Taiwanese women. We therefore designed this study to investigate the clinical roles of lncRNAs HOTAIR SNPs in cervical cancer. One hundred and sixteen patients with cervical invasive cancer and 96 patients with preinvasive lesions as well as 318 control women were consecutively recruited. LncRNAs HOTAIR SNPs rs920778, rs12427129, rs4759314 and rs1899663 were analyzed and their genotypic frequencies were examined by real time polymerase chain reaction. The results indicated that there were no genotypic differences between patients with cervical neoplasia and normal controls as well as among patients with invasive and invasive cancer, and normal controls. However, genotype GG in lncRNAs HOTAIR SNP rs920778 was demonstrated to be a predictor for poorer cancer recurrence probability [p=0.001, hazard ratio (HR): 7.25, 95% CI: 2.19-23.96]. Furthermore, cervical cancer patients with genotype GG in lncRNAs HOTAIR rs920778 had worse overall survival (p =0.002, HR: 7.22, 95% CI: 2.09-24.92). No significant associations exhibited between lncRNAs HOTAIR SNP rs920778 and clinicopathological parameters. In conclusion, this studied lncRNAs HOTAIR SNPs are not associated with cervical carcinongensis. However, lncRNAs HOTAIR SNP rs920778 may be regarded as an independent predictor of cancer recurrence probability and overall survival in cervical cancer patients. PMID- 30275758 TI - Estrogen Receptor 1 (ESR1) Enhances Slc2a4/GLUT4 Expression by a SP1 Cooperative Mechanism. AB - Background: Estrogens are involved in glycemic regulation, playing an important role in the development and/or progression of insulin resistance. For that, estrogens regulate the expression of the glucose transporter protein GLUT4 (codified by the solute carrier family 2 member 4 gene, Slc2a4), thus modulating adipose and muscle glucose disposal. This regulation is a balance between ESR1 mediated enhancer effect and ESR2-mediated repressor effect on Slc2a4 gene. However, molecular mechanisms involved in these effects are poorly understood. Since the specificity protein 1 (SP1) participates in several ESR-mediated genomic regulations, the aim of the present study is to investigate the participation of SP1 in the ESR1/2-mediated regulation of Slc2a4 gene. Methods: Differentiated 3T3-L1 adipocytes were 24-hour challenged with 10 nM estradiol (E2) and 10 nM ESR1 agonist (PPT) or 100 nM ESR2 agonist (DPN), added or not with E2. Slc2a4 and Sp1 mRNAs (RT-qPCR), total GLUT4 and nuclear ESR1, ESR2 and SP1 proteins (Western blotting), SP1 binding activity into Slc2a4 promoter (EMSA), and nuclear complexation of SP1/ESR1 (immunoprecipitation) were analyzed. Results: E2 and PPT increased (25-50%) whereas DPN reduced (20-45%) Slc2a4 and GLUT4 expression. Nuclear content of ESR1 and ESR2 remained unchanged. Nuclear content of SP1 increased (50 to 90%) by PPT and DPN added or not with E2; the highest effect observed with PPT alone. PPT also increased the nuclear content of SP1/ESR1 complex and the SP1 binding into the Slc2a4 promoter. Conclusions: ESR1 activation in adipocytes increased the nuclear content of SP1 protein, the SP1/ESR1 interaction and SP1 binding into the Slc2a4 gene promoter, culminating with increased Slc2a4/GLUT4 expression. No involvement of SP1 seems to occur in ESR2-mediated repressor effect on Slc2a4. We expect that this ESR1/SP1 cooperative effect can contribute to the development of new approaches for prevention or treatment of insulin resistance and diabetes mellitus. PMID- 30275759 TI - Mitochondrial NADH Dehydrogenase Subunit 3 (MTND3) Polymorphisms are Associated with Gastric Cancer Susceptibility. AB - Accumulating evidence indicates that mitochondrial DNA alterations contribute to cancer development and progression. In this study, we evaluated the relationship between polymorphisms of mitochondrial NADH dehydrogenase subunit 3 (MTND3) and the risk of gastric cancer (GC). Five single nucleotide polymorphisms (SNPs; rs28358278, rs2853826, rs201397417, rs41467651, and rs28358275) were identified and genotyped in 377 patients with GC patients and 363 controls by direct sequencing. The rs41467651 T allele was significantly associated with GC risk [adjusted odds ratio (OR) = 2.11, 95% confidence interval (CI) = 1.25-3.55, P = 0.005). In stratified analysis, rs28358278, rs2853826, and rs41467651 were associated with subgroups of GC, with the rs28358278 G, rs2853826 T, and rs41467651 T alleles associated with an increased GC risk in females (adjusted OR = 1.70, 95% CI = 1.08-2.69, P = 0.023; adjusted OR = 1.78, 95% CI = 1.11-2.85, P = 0.016; adjusted OR = 2.07, 95% CI = 1.04-4.12, P = 0.038, respectively). The rs441467651 T allele was also related with GC risk in diffuse-type subjects compared to that of controls (adjusted OR = 2.61, 95% CI = 1.43-4.89, P = 0.002). In addition, The rs441467651 T allele was significantly related with increased GC risk regardless of lymph node metastasis (LNM), T classification, and tumor stage compared to that of controls (adjusted OR = 2.00, 95% CI = 1.12-3.55, P = 0.019 in LNM-negative subjects; adjusted OR = 2.10, 95% CI = 1.05-4.22, P = 0.0379 in LNM-positive subjects; adjusted OR = 1.82, 95% CI = 1.02-3.24, P = 0.042 in T1/T2 subjects; adjusted OR = 2.60, 95% CI = 1.29-5.24, P = 0.007 in T3/T4 subjects; adjusted OR = 1.91, 95% CI = 1.09-3.34, P = 0.025 in tumor stage I (A+B)/II (A+B+C) subjects; adjusted OR = 2.36, 95% CI = 1.12-5.13, P = 0.025 in tumor stage III (A+B+C) subjects) compared to that of controls. Our findings suggest that the rs28358278, rs2853826, and rs41467651 polymorphisms of MTND3 increase the susceptibility to GC development. PMID- 30275760 TI - Impact of ADAM10 gene polymorphisms on hepatocellular carcinoma development and clinical characteristics. AB - A disintegrin and metalloprotease (ADAM) family proteins are type-I transmembrane glycoproteins with multiple functions in cell adhesion, migration, proteolysis and signaling. ADAM10 is a member of the ADAM family reportedly involved in cancer progression and has been shown to be overexpressed in hepatocellular carcinoma (HCC) tissues and significantly associated with tumor progression and shortened survival. This study investigated ADAM10's single nucleotide polymorphisms (SNPs) and their association to HCC development and regulation. Real-time polymerase chain reaction was used to analyze five SNPs of ADAM10 in 333 patients with HCC and 1196 controls without cancer. The results indicated that of the 333 patients with HCC, those who carried ADAM10 rs514049 (AC + CC) variants had a higher risk of developing lymph node metastasis (odds ratio [OR] = 5.087, p = 0.027), and those who carried ADAM10 rs653765 (GA + AA) variants had a higher risk of developing distant metastasis (OR = 3.346, p = 0.020) and higher levels of alpha-fetoprotein. In conclusion, our study demonstrated that the SNPs of ADAM10 are involved in HCC progression. ADAM10 SNPs may be used as therapeutic targets to evaluate poor prognoses for HCC. PMID- 30275761 TI - Thrombopoietin could protect cerebral tissue against ischemia-reperfusion injury by suppressing NF-kappaB and MMP-9 expression in rats. AB - Objective: To determine the neuroprotective effects and underpinning mechanisms of thrombopoietin (TPO), Matrix Metalloproteinase-9(MMP-9) and Nuclear Factor kappaB (NF-kappaB) after focal cerebral ischemia-reperfusion in rats. Methods: Male rats underwent 2 hours of right middle cerebral artery occlusion (MCAO) followed by 22 hours of reperfusion. PBS or TPO (0.1ug/kg) was administered from caudal vein before reperfusion. Neurologic deficits, brain edema, Evans blue (EB) extravasation, NF-kappaB and MMP-9 expression were subsequently examined. Results: Ischemia-reperfusion injury produced a large area of edema. TPO significantly reduced edema and alleviated neurologic deficits after ischemia reperfusion. Ischemia-induced increases of NF-kappaB, MMP-9 and Evans blue extravasation were reduced by TPO intervention. Conclusion: TPO improved neurological function and ameliorated brain edema after stroke, partly by reducing the ischemia-induced increase of NF-kappaB and MMP-9. PMID- 30275762 TI - GABAergic Alterations in the Rat Testis after Methamphetamine Exposure. AB - Gamma-aminobutyric acid (GABA), GABA-A receptors and GABA transporter 1 (GAT1) were reported to be involved in the proliferation of Leydig cells, testosterone production and spermatogenesis. Since methamphetamine (METH) has been reported to have adverse effects on testis and its functions, the aim of this study was therefore to determine the changes of GABAergic activity in testis after METH exposure. Male Sprague-Dawley rats were divided into control, acute binge (AB METH), escalating dose (ED METH) and escalating dose-binge (ED-binge METH) groups. After sacrifice, rat testes were removed and used to estimate GABA concentration and the expression of GABA-A receptor, GAD1, GAD2 and GAT1 genes by using HPLC and RT-PCR, respectively. The GABA concentration was significantly increased in all METH-administrated groups. In addition, significant increases of GABA-A alpha1 receptor and GAD1 genes expression were found in the ED-binge METH group. Gene expressions of GAT1 were numerically decreased in all METH administrated rats and reached significant in the ED METH group. These results indicated a compensatory upregulation of GABA production and its functions in testis after METH exposure. Thus, these changes might represent a homeostatic response of GABAergic to the adverse effects of METH.

AB - [This corrects the article DOI: 10.7150/ijms.19124.]. PMID- 30275764 TI - AGK2, A SIRT2 Inhibitor, Inhibits Hepatitis B Virus Replication In Vitro And In Vivo. AB - Sirtuin 2 (SIRT2) is a nicotinamide adenine dinucleotide (NAD +)-dependent class III histone deacetylase. We have reported that HBx (hepatitis B virus X protein) elevated SIRT2 promotes HBV replication and hepatocarcinogenesis. However, the potential anti-HBV effect of AGK2, a selective inhibitor of SIRT2, has not been reported. Here, the role of AGK2 on HBV replication was examined in the HepAD38 and HepG2-NTCP cell lines. The HBV genome was stably integrated in HepAD38 cell line which expresses HBV under the control of tetracycline. The HepG2-NTCP cells expressing the sodium taurocholate cotransporting polypeptide (NTCP) receptor are susceptible to HBV infection. We found that AGK2 exhibited a robust anti-HBV activity with minimal hepatotoxicity. AGK2 inhibited the expression of HBV total and 3.5kb RNAs, DNA replicative intermediates and HBV core protein (HBc). Moreover, AGK2 treatment suppressed the secretion of the hepatitis B e antigen (HBeAg) and hepatitis B surface antigen (HBsAg). Importantly, AGK2 treatment inhibited serum HBV DNA, HBeAg and HBsAg levels as well as hepatic HBV DNA, RNA and HBc in the HBV transgenic mice. The results indicated that AGK2, as a SIRT2 inhibitor, might be a new therapeutic option for controlling HBV infection. PMID- 30275765 TI - Acid-electrolyzed functional water induces extracellular matrix metalloproteinase inducer, a possible novel alarmin, secretion from oral squamous cell carcinoma cell lines. AB - Extracellular matrix metalloproteinase inducer (EMMPRIN) secretion was induced in the oral squamous cell carcinoma cell line HSC3 cell by acid-electrolyzed functional water (FW) stimulation. Augmented EMMPRIN secretion was not under transcriptional control; rather, it was derived from the intracellular storages. EMMPRIN secretion was also induced under oxidative stress and accompanied by the release of lactate dehydrogenase (LDH). The molecules released from cells undergoing necrosis are called as alarmins, and the secretion of IL-1alpha, a typical alarmin, was induced by FW stimulation and oxidative stress. Intracellular localization was examined by cell fractionation. A significant amount of EMMPRIN was localized in the triton X-100 and DNase sensitive fractions; the levels were drastically reduced following FW treatment. The function of the released EMMPRIN was examined using the monocytic cell line THP1. Culture supernatant derived from FW-treated HSC3 cells induced the expression of matrix metalloproteinases (MMPs) 1, 2, 8, 9, 13, and 14, platelet-derived growth factor, and interleukin-8. In contrast, vascular endothelial growth factor expression was reduced. Induction of these factors was abolished following eliminating of EMMPRIN by immunoprecipitation. These results indicate that EMMPRIN might be considered as a type of alarmin that transduces danger signals to the surrounding cells. PMID- 30275766 TI - The Relationship between Follicle-stimulating Hormone and Bone Health: Alternative Explanation for Bone Loss beyond Oestrogen? AB - Bone loss in women commences before the onset of menopause and oestrogen deficiency. The increase of follicle-stimulating hormone (FSH) precedes oestrogen decline and may be a cause for bone loss before menopause. This review summarizes the current evidence on the relationship between FSH and bone derived from cellular, animal and human studies. Cellular studies found that FSH receptor (FSHR) was present on osteoclasts, osteoclast precursors and mesenchymal stem cells but not osteoblasts. FSH promoted osteoclast differentiation, activity and survival but exerted negligible effects on osteoblasts. Transgenic FSHR or FSH knockout rodents showed heterogenous skeletal phenotypes. Supplementation of FSH enhanced bone deterioration and blocking of FSH action protected bone of rodents. Human epidemiological studies revealed a negative relationship between FSH and bone health in perimenopausal women and elderly men but the association was attenuated in postmenopausal women. In conclusion, FSH may have a direct action on bone health independent of oestrogen by enhancing bone resorption. Its effects may be attenuated in the presence of overt sex hormone deficiency. More longitudinal studies pertaining to the effects of FSH on bone health, especially on fracture risk, should be conducted to validate this speculation. PMID- 30275767 TI - B355252, A Novel Small Molecule, Confers Neuroprotection Against Cobalt Chloride Toxicity In Mouse Hippocampal Cells Through Altering Mitochondrial Dynamics And Limiting Autophagy Induction. AB - Cerebral hypoxia as often occurs in cases of stroke, hemorrhage, or other traumatic brain injuries, is one of the leading causes of death worldwide and a main driver of disabilities in the elderly. Using a chemical mimetic of hypoxia, cobalt chloride (CoCl2), we tested the ability of a novel small molecule, 4 chloro-N-(naphthalen-1-ylmethyl)-5-(3-(piperazin-1-yl)phenoxy)thiophene-2 sulfonamide (B355252), to alleviate CoCl2-induced damage in mouse hippocampal HT22 cells. A dose-dependent decrease in cell viability was observed during CoCl2 treatment along with increases in mitochondrial membrane potential and generation of reactive oxygen species (ROS). B355252 conferred protection against these changes. We further found that mitochondrial dynamics, the balance between mitochondrial fusion and fission, were perturbed by CoCl2 treatment. Mitochondrial fusion, which was assessed by measuring the expression of proteins optic atrophy protein 1 (OPA1) and mitofusin 2 (Mfn2), declined due to CoCl2 exposure, but B355252 addition was able to elevate Mfn2 expression while OPA1 expression was unchanged. Mitochondrial fission, measured by phosphorylated dynamin-related protein 1 (p-DRP1) and fission protein 1 (FIS1) expression, also decreased following CoCl2 exposure, and was stabilized by B355252 addition. Finally, autophagy was assessed by measuring the conversion of cytosolic microtubule-associated protein 1A/1B-light chain three-I (LC3-I) to autophagosome bound microtubule-associated protein 1A/1B-light chain three-II (LC3-II) and was found to be increased by CoCl2. B355252 addition significantly reduced autophagy induction. Taken together, our results indicate B355252 has therapeutic potential to reduce the damaging effects caused by CoCl2 and should be further evaluated for applications in cerebral ischemia therapy. PMID- 30275768 TI - The Emperor's New Clothes: a Critical Appraisal of Evidence-based Medicine. AB - Evidence-Based Medicine (EBM) is the way we are expected to deliver our healthcare in the 21st century. It has been described as the integration of information from best available evidence with the doctor's experience and the patient's point of view. Unfortunately, the original meaning of EBM has been lost and the worldwide medical community has shifted the paradigm to Guidelines-Based Medicine, that has displaced the figures of the doctor and the patient from the decision-making process and relegated them to mere executor and final target of decisions taken by someone else. Problems related to the reliability of evidence and to the way guidelines are constructed, implemented and followed are discussed in detail. It is mandatory that the whole medical community takes responsibility and tries to reverse this apparently inexorable process so to re-establish a proper evidence-based care, where patients and their healing relation with practitioners are at the centre and where doctors are able to critically evaluate the available evidence and use it in light of their personal experience and knowledge. PMID- 30275769 TI - Characterization and potential roles of bone marrow-derived stromal cells in cancer development and metastasis. AB - Background: The tumor microenvironment and its stromal cells play an important role in cancer development and metastasis. Bone marrow-derived cells (BMDCs), a rich source of hematopoietic and mesenchymal stem cells, putatively contribute to this tumoral stroma. However their characteristics and roles within the tumor microenvironment are unclear. In the present study, BMDCs in the tumor microenvironment were traced using the green fluorescent protein (GFP) bone marrow transplantation model. Methods: C57BL/6 mice were irradiated and rescued by bone marrow transplantation from GFP-transgenic mice. Lewis lung cancer cells were inoculated into the mice to generate subcutaneous allograft tumors or lung metastases. Confocal microscopy, immunohistochemistry for GFP, alpha-SMA, CD11b, CD31, CD34 and CD105, and double-fluorescent immunohistochemistry for GFP-CD11b, GFP-CD105 and GFP-CD31 were performed. Results: Round and dendritic-shaped GFP positive mononuclear cells constituted a significant stromal subpopulation in primary tumor peripheral area (PA) and metastatic tumor area (MA) microenvironment, thus implicating an invasive and metastatic role for these cells. CD11b co-expression in GFP-positive cells suggests that round/dendritic cell subpopulations are possibly BM-derived macrophages. Identification of GFP positive mononuclear infiltrates co-expressing CD31 suggests that these cells might be BM-derived angioblasts, whereas their non-reactivity for CD34, CD105 and alpha-SMA implies an altered vascular phenotype distinct from endothelial cells. Significant upregulation of GFP-positive, CD31-positive and GFP/CD31 double positive cell densities positively correlated with PA and MA (P<0.05). Conclusion: Taken together, in vivo evidence of traceable GFP-positive BMDCs in primary and metastatic tumor microenvironment suggests that recruited BMDCs might partake in cancer invasion and metastasis, possess multilineage potency and promote angiogenesis. PMID- 30275771 TI - The experimental study of shunt-decompression arterialized vein flap. AB - Background: Arterialized vein flap is a kind of unphysiological flap. Unphysiological reconstruction of blood circulation leads to higher load than that supported by physiological flap and is the culprit of flap swelling, blood stasis, skin blistering, and necrosis after flap grafting. To resolve the multiple disadvantages of traditional flap grafting, by introducing the principles of fluid mechanics, shunt-decompression surgery is prepared to decline the circulation preload and improve the prognosis of arterialized vein flap grafting. Methods: By introducing the principles of fluid mechanics, we established the model of shunt-decompression arterialized vein flap, which satisfied the common properties of general fluid that the interface pressure between object and fluid is reduced when the velocity of fluid is increased and vice versa-the effect of Bernoulli. Under this rule, we anastomose the arterialized vein to the branch of main artery of recipient region or make end-to side anastomosis, which can maintain the blood flow of main artery, decrease the perfusion of flap, and preserve the decompressive effect of main artery to branches. From March, 2016 to September, 2016, we performed animal experiments on ten male bama mini pigs with average weight of 28 +/- 2.35 kg. Superior epigastric artery of pig was used for feeding artery to arterialize the superficial epigastric veins. The total area of flap is 8 cm * 6 cm. End-to-side anastomosis and end-to-end anastomosis were established in experimental group and control group, respectively. Doppler speckle perfusion imaging apparatus was used to monitor the alterations of flap perfusion, blood flow of flap, tissue swelling and survival of flaps. Results: The average flap perfusion (PU) at 1 week after surgery is 83.62 +/- 3.14 in experimental group and 98.14 +/- 6.54 in control group, respectively (P < 0.05), indicating the significant reduction of flap blood perfusion in experimental group as compared with control group. As to the survival of flaps, 7 flaps completely survived, 3 showed partial necrosis, and no one was found as complete necrosis in experimental group, while only 3 flaps survived, and 4 flaps and 3 flaps showed partial necrosis and complete necrosis in control group, respectively (P < 0.05). Conclusion: Based on the physiological features of arterialized vein flap and its problems in clinical application, we improved the anastomosis strategy of flap grafting and obtained excellent experimental outcomes, which provides an insight for the clinical application of arterialized vein flaps. PMID- 30275770 TI - Role of TCF/LEF Transcription Factors in Bone Development and Osteogenesis. AB - Bone formation occurs by two distinct mechanisms, namely, periosteal ossification and endochondral ossification. In both mechanisms, osteoblasts play an important role in the secretion and mineralization of bone-specific extracellular matrix. Differentiation and maturation of osteoblasts is a prerequisite to bone formation and is regulated by many factors. Recent experiments have shown that transcription factors play an important role in regulating osteoblast differentiation, proliferation, and function. Osteogenesis related transcription factors are the central targets and key mediators of the function of growth factors, such as cytokines. Transcription factors play a key role in the transformation of mesenchymal progenitor cells into functional osteoblasts. These transcription factors are closely linked with each other and in conjunction with bone-related signaling pathways form a complex network that regulates osteoblast differentiation and bone formation. In this paper, we discuss the structure of T cell factor/lymphoid enhancer factor (TCF/LEF) and its role in embryonic skeletal development and the crosstalk with related signaling pathways and factors. PMID- 30275772 TI - Marsdenia tenacissima extract induces apoptosis and suppresses autophagy through ERK activation in lung cancer cells. AB - Background: Marsdenia tenacissima is an herb medicine which has been utilized to treat malignant diseases for decades. The M. tenacissima extract (MTE) shows significant anti-proliferation activity against non-small cell lung cancer (NSCLC) cells, but the underlying mechanisms remain unclear. In this study, we explored the potential anti-proliferation mechanisms of MTE in NSCLC cells in relation to apoptosis as well as autophagy, which are two critical forms to control cancer cell survival and death. Methods: The proliferation of H1975 and A549 cells was evaluated by MTT assay. Cell apoptosis was assessed by Annexin V and PI staining, Caspase 3 expression and activity. Autophagy flux proteins were detected by Western blot with or without autophagy inducer and inhibitor. Endogenous LC3-II puncta and LysoTracker staining were monitored by confocal microscopy. The formation of autophagic vacuoles was measured by acridine orange staining. ERK is a crucial molecule to interplay with cell autophagy and apoptosis. The role of ERK on cell apoptosis and autophagy influenced by MTE was determined in the presence of MEK/ERK inhibitor U0126. Results: The significant growth inhibition and apoptosis induction were observed in MTE treated NSCLC cells. MTE induced cell apoptosis coexisted with elevated Caspase 3 activity. MTE also impaired autophagic flux by upregulated LC3-II and p62 expression. Autophagy inducer EBSS could not abolish the impaired autophagic flux by MTE, while it was augmented in the presence of autophagy inhibitor Baf A1. The autophagosome lysosome fusion was blocked by MTE via affecting lysosome function as evidenced by decreased expression of LAMP1 and Cathepsin B. The molecule ERK became hyperactivated after MTE treatment, but the MEK/ERK inhibitor U0126 abrogated autophagy inhibition and apoptosis induction caused by MTE, suggested that ERK signaling pathways partially contributed to cell death caused by MTE. Conclusion: Our results demonstrate that MTE caused apoptosis induction as well as autophagy inhibition in NSCLC cells. The activated ERK is partially associated with NSCLC apoptotic and autophagic cell death in response to MTE treatment. The present findings reveal new mechanisms for the anti-tumor activity of MTE against NSCLC. PMID- 30275775 TI - A Tribute to John L. Ochsner, Sr., MD. PMID- 30275773 TI - Circulating activated protein C levels are not increased in septic patients treated with recombinant human soluble thrombomodulin. AB - Background: Recombinant human soluble thrombomodulin (rTM) has been used for the treatment of disseminated intravascular coagulation in Japan, and an international phase III clinical trial for rTM is currently in progress. rTM mainly exerts its anticoagulant effects through an activated protein C (APC) dependent mechanism, but the circulating APC levels after rTM treatment have not been clarified. This prospective observational study investigated plasma APC levels after rTM treatment. Methods: Plasma levels of soluble thrombomodulin, thrombin-antithrombin complex (TAT), protein C, and APC were measured in eight septic patients treated with rTM. APC generation in vitro was assessed in the presence or absence of rTM. Results: rTM significantly increased thrombin mediated APC generation in vitro. In septic patients, soluble thrombomodulin levels were significantly increased during a 30-60-min period of rTM treatment and TAT levels were decreased. However, APC activity was not increased during the treatment period. Conclusions: Plasma APC activity is not increased in septic patients treated with rTM. It is possible that APC acts locally and does not circulate systemically. PMID- 30275774 TI - A New ELISA to Overcome the Pitfalls in Quantification of Recombinant Human Monoclonal Anti-HBs, GC1102, by Commercial Immunoassays. AB - Several methods for the quantification of human anti-HBs, an antibody to hepatitis B surface antigen (HBsAg), have been developed based on enzyme reaction, chemiluminescence, fluorescence, and radioactivity for application to human serum or plasma. Commercial anti-HBs immunoassay kits use a sandwich method in which a bridge is formed by the anti-HBs between a HBsAg immobilized solid matrix and the labeled HBsAg. However, this direct sandwich enzyme-linked immunosorbent assay (ELISA) is insufficient to accurately evaluate the activity of the human monoclonal anti-HBs, GC1102. As an alternative, we developed an indirect anti-HBs ELISA (anti-HBs qELISA_v.1) that improved detection of anti HBs. In this current study, we further optimized this indirect method to minimize nonspecific binding of human serum, by employing incubation buffers containing animal serum, Tween 20, skim milk, and a low pH washing buffer. This new and improved method, termed anti-HBs qELISA_v.2, showed accurate quantification of plasma-derived hepatitis B immune globulin (HBIG) and was comparable to results obtained with commercial ELISA (r = 0.93) and RIA (r = 0.85) kits. Further, the GC1102 in human serum could be precisely measured using the anti-HBs qELISA_v.2 without limitations of nonspecific binding.

PMID- 30275782 TI - Predicting American Board of Emergency Medicine Qualifying Examination Passage Using United States Medical Licensing Examination Step Scores. AB - Background: The objective of the current study was to determine whether emergency medicine residents' United States Medical Licensing Examination (USMLE) scores are significantly associated with first-attempt passage of the American Board of Emergency Medicine (ABEM) qualifying (written) examination. We hypothesized that USMLE Step 2 Clinical Knowledge (CK) scores would be useful in predicting students who passed the ABEM qualifying examination on their first attempt. Methods: For this retrospective cohort study, we examined the data of residents who successfully completed training at two emergency medicine residency programs between the years 2002-2013. Because scores on the USMLE Step examinations varied greatly across years, we obtained means and standard deviations from the National Board of Medical Examiners. We subtracted the mean score for the year each resident took the examination from the resident's examination score, creating centered Step 1 and centered Step 2 CK scores. Results: A multivariate logistic regression analysis indicated that centered Step 2 CK scores could be used to predict the odds of passing the ABEM qualifying examination (odds ratio = 1.05 [95% confidence interval 1.02 to 1.08, P < 0.001]). Using a Step 2 CK score cutoff of 7 points lower than the mean yielded 64% sensitivity and 81% specificity for predicting passage of the ABEM written examination on the first attempt. Conclusion: Program directors and selection committees may wish to consider whether applicants' Step 2 CK scores are near the national average when making ranking decisions, as this variable is highly predictive of passing the ABEM qualifying examination on the initial attempt. PMID- 30275783 TI - Treatment of Occipital Neuralgia by Thermal Radiofrequency Ablation. AB - Background: Occipital neuralgia is an uncommon disorder characterized by severe pain involving the posterior scalp in the distribution of the greater and lesser occipital nerves. In cases refractory to pharmacotherapy, invasive treatment options may be warranted. The aim of the present study was to examine the effects of thermal radiofrequency ablation (TRF) on occipital neuralgia. We hypothesized that this procedure would result in long-term pain relief. Methods: All patients who underwent TRF of the greater and lesser occipital nerves between January 1, 2013 and March 23, 2016 were identified. Medical records were reviewed for preprocedure pain score, 1-month postprocedure pain score, patient-defined percent pain relief according to the visual analog scale (on which zero equals no pain and 10 represents the worst pain imaginable), and length of pain relief. The primary outcomes were the differences between preprocedure and 1-month postprocedure pain scores (mean change from baseline), percent pain relief, and patient-reported length of relief. Results: A total of 50 patients were identified; 4 patients were excluded because of insufficient data as a result of loss to follow-up. A significant difference was found between preprocedure and postprocedure patient-reported pain scores (6.7 vs 2.7, respectively; P < 0.001), equating to a mean reduction in pain scores 1-month postprocedure of 4.0 +/- 3.3. The mean patient-defined percent pain relief was 76.3% +/- 25.0%. The mean patient-reported length of relief was 6.5 +/- 5.1 months. Conclusion: This study suggests that TRF may reduce pain scores for approximately 6 months. PMID- 30275784 TI - Rhabdomyolysis: Patterns, Circumstances, and Outcomes of Patients Presenting to the Emergency Department. AB - Background: Exertional rhabdomyolysis is a condition resulting from skeletal muscle damage and release of intracellular toxins into the systemic circulation as a consequence of extreme physical effort. With increasing numbers of people partaking in high-intensity workouts, we hypothesized that the rate of presentation of exertional rhabdomyolysis was also increasing. Methods: All presentations to the Princess Alexandra Hospital emergency department in Brisbane, Australia between March 2005 and December 2016 were identified from the electronic medical record. Records of patients with a serum creatine kinase value >1,000 U/L or a urinary myoglobin >5 mg/L were extracted for determination of whether the rhabdomyolysis was attributable to physical exertion. Results: From a total of 1,957 rhabdomyolysis cases, 89 patients (70.8% male) were identified as having exertional rhabdomyolysis. The frequency of presentation increased from 0.28/10,000 presentations in 2005 to 3.5/10,000 in 2015. Gym-induced exertional rhabdomyolysis was the primary subcategory (53.9%) for these cases, and manual labor was the second most common subcategory (15.7%). Conclusion: This study provides evidence for increasing instances of exertional rhabdomyolysis in the Brisbane, Australia metropolitan area and adds to the current knowledge about those who develop exertional rhabdomyolysis. Future studies are warranted to investigate if similar trends are being seen in other regions and to identify the circumstances leading to the presentation. Such knowledge would be valuable for devising strategies to prevent and mitigate injury. PMID- 30275785 TI - Successful Treatment of Cesarean Scar Pregnancy With Suction Curettage: Our Experiences in Early Pregnancy. AB - Background: Cesarean scar pregnancy is an ectopic pregnancy embedded in the myometrium of a cesarean scar. Several types of conservative treatment have been used to treat cesarean scar pregnancy, but no management protocol has been established for this rare, life-threatening condition. The purpose of this study was to evaluate the feasibility of suction curettage as a first-line treatment in early cesarean scar pregnancy. Methods: During a 4-year period, 19 cases of cesarean scar pregnancy were diagnosed at Suleymaniye Maternity Hospital in Istanbul, Turkey. Suction curettage and Foley balloon tamponade were performed as a first-line treatment in 13 patients. Medical records and treatment results of the patients were evaluated. Results: The mean maternal age was 32.5 years (range, 24-39 years). The mean gestational sac diameter was 13.65 mm (range, 7.6 27 mm), and mean endometrial thickness was 10.7 mm (range, 6.7-14.6 mm). A measurable fetal pole for crown-rump length was available for 6 (46.1%) patients. None of the fetuses had cardiac activity. Suction curettage under ultrasound guidance and Foley balloon tamponade were successful as the primary treatment in 13 of 13 patients. No major complications occurred during or after the procedure. Conclusion: Our data suggest that surgical evacuation under ultrasound guidance with Foley balloon tamponade is a safe and successful treatment modality in carefully selected patients with early cesarean scar pregnancy. PMID- 30275786 TI - Effect of Obesity on Component Alignment in Total Knee Arthroplasty. AB - Background: Obesity is routinely cited as a negative predictive factor for outcomes after total knee arthroplasty (TKA), but the direct mechanism responsible for this relationship has not been described. One possible explanation is a propensity for component malalignment in obese patients that is attributable to difficulty with surgical exposure. Methods: This study evaluated the effect of obesity on TKA component alignment in 251 primary TKAs during a 12 month period at a single center in 2009. Postoperative component alignment was retrospectively measured and compared between patients defined as obese (body mass index [BMI] >=30 kg/m2) and patients defined as nonobese (BMI <30 kg/m2). Alignment was determined by measuring the coronal tibiofemoral angle, coronal femoral component angle, coronal tibial component angle, sagittal femoral component angle, and sagittal tibial component angle in all of the study patients. Results: Statistical analysis failed to demonstrate a statistically significant relationship between obesity and component alignment in any of the measured parameters. Conclusion: The results of this study support that obesity does not negatively affect TKA component alignment; another factor must be associated with the worse outcomes in obese patients undergoing TKA. PMID- 30275787 TI - Hyponatremia in Association With Second-Generation Antipsychotics: A Systematic Review of Case Reports. AB - Background: Hyponatremia is generally defined as a serum sodium level <135 mmol/L and is considered severe if serum sodium is <125 mmol/L. Hyponatremia is a potentially life-threatening medical comorbidity for patients with schizophrenia. The incidence of hyponatremia in patients with schizophrenia who are taking second-generation antipsychotics (SGAs) has not been well established. Methods: We conducted a systematic review of case reports of hyponatremia associated with the use of SGAs in patients with schizophrenia. We searched MEDLINE (from 1946 through September 2016) using the medical subject headings antipsychotic agents, hyponatremia, and water intoxication to identify reported diagnoses of hyponatremia following treatment with SGAs in patients with schizophrenia. Results: We abstracted 12 potentially relevant case reports from 157 records. Nine case reports met the selection criteria. Three cases involved the use of aripiprazole (Abilify), 3 involved the use of risperidone (Risperdal), and the other 3 cases involved ziprasidone, olanzapine, and clozapine. Approximately equal numbers of males and females were represented, and 2 of the 9 patients were aged >=60 years. The average patient age was 47 years, and the average time to the hyponatremia event was 17 days. The average serum sodium was 138 mmol/L at baseline, 112 mmol/L at treatment nadir, and 138 mmol/L after treatment discontinuation. Conclusion: Hyponatremia can result from the use of SGAs in patients with schizophrenia and can be avoided with proper management of treatment. Physicians, psychiatrists, and other healthcare workers should be aware of the potential for severe hyponatremia with the use of commonly prescribed SGAs. SGA-induced hyponatremia is generally reversible after discontinuing treatment. PMID- 30275788 TI - Advances in Neuro-Oncology Imaging Techniques. AB - Background: Central nervous system (CNS) tumors are a rare but devastating malignancy, often robbing patients of the basic quality of life. Despite advances in our understanding of the CNS tumor disease processes, the prognosis for patients with CNS tumors remains poor. Better characterization and diagnostic and monitoring approaches are necessary to assist in diagnosis and treatment of CNS tumors. One important tool in the neuro-oncology armamentarium is the use of advanced imaging techniques. Methods: We searched PubMed using the keywords neuro oncology imaging, pseudoprogression, molecular imaging, and biomarkers. We limited our search to full-text English articles and identified other relevant articles from the reference lists of previously identified articles. Results: Advances in imaging techniques have allowed investigators to explore various imaging modalities, from tumor characterization to differentiating pseudoprogression from tumor progression. Better imaging can result in better diagnostic approaches, greater and safer resection techniques, and improved monitoring of tumor progression. Conclusion: This review highlights advances in neuro-oncology imaging techniques and their clinical utility in the treatment and management of primary brain tumors. PMID- 30275789 TI - Dislocation of the Hip: A Review of Types, Causes, and Treatment. AB - Background: Dislocation of the hip is a well-described event that occurs in conjunction with high-energy trauma or postoperatively after total hip replacement. Methods: In this review, the types, causes, and treatment modalities of hip dislocation are discussed and illustrated, with particular emphasis on the assessment, treatment, and complications of dislocations following total hip replacement. Results: Hip dislocations are commonly classified according to the direction of dislocation of the femoral head, either anterior or posterior, and are treated with specific techniques for reduction. Generally, closed reduction is the initial treatment method, usually occurring in the emergency room. Bigelow first described closed treatment of a dislocated hip in 1870, and since then many reduction techniques have been proposed. Each method has unique advantages and disadvantages. Anterior hip dislocation is commonly reduced by inline traction and external rotation, with an assistant pushing on the femoral head or pulling the femur laterally to assist reduction. Posterior hip dislocations are the most common type and are reduced by placing longitudinal traction with internal rotation on the hip. Conclusion: Patients with hip dislocations must receive careful diagnostic workup, and the treating physician must be well versed in the different ways to treat the injury and possible complications. Timely evaluation and treatment, including recognizing the potential complications, are necessary to offer the best outcome for the patient. PMID- 30275790 TI - Role of Complementary and Alternative Medicine in Otolaryngologic Perioperative Care. AB - Background: During the perioperative period for otolaryngologic surgical cases, complications and delays can occur as the result of anxiety, pain, nausea, and vomiting. Conventional methods used to treat these symptoms include medications that can be expensive and invasive or that can cause adverse effects. Because of the concerns about opioid use in the United States, providers might want to consider using complementary and alternative medicine (CAM) as adjunctive or primary treatment plans. Methods: To assess the current knowledge about the clinical effectiveness of CAM for patients undergoing otolaryngologic procedures, we searched the literature using MEDLINE, PubMed, and Google Scholar. We excluded studies published prior to 1990 and articles about surgeries that were unrelated to otolaryngology. Results: An analysis of the selected studies revealed that CAM therapies-acupuncture, aromatherapy, hypnosis, and music therapy-have been shown to be effective at reducing preoperative anxiety, postoperative pain, and postoperative nausea and vomiting. No adverse side effects were associated with CAM use in these studies. Conclusion: The use of CAM in patients undergoing otolaryngologic surgeries may relieve common perioperative symptoms. While further study is warranted, otolaryngology providers might consider implementing CAM with patients electing surgery. PMID- 30275791 TI - Non-Human Leukocyte Antigen Antibody-Mediated Lung Transplant Rejection: The Other Anti-A. AB - Background: Acute rejection of lung allografts is an important contributor to morbidity and mortality in the transplant patient population, resulting in the dysfunction and destruction of the graft by the host's immune system via cellular or antibody-mediated mechanisms. Acute cellular rejection (ACR) is more common and better characterized than antibody-mediated rejection, which to date lacks any widely agreed upon, standardized set of diagnostic criteria. We present a case of AMR attributable to a rare phenomenon, non-human leukocyte antigen (HLA) antibodies. Case Report: A 50-year-old male underwent an uneventful single lung transplant for pulmonary sarcoidosis. Donor and recipient blood type was A positive. No pretransplant donor-specific antibodies were identified. Flow cytometric crossmatch was negative. The postoperative course was significant for a single-unit transfusion of packed red blood cells on postoperative day (POD) 1 and persistent asymptomatic Serratia marcescens in bronchial washes despite ongoing levofloxacin treatment. A surveillance biopsy (POD 34) showed no evidence of rejection. One week later (on POD 41), the patient presented with fever, shortness of breath, and imaging abnormalities of the grafted lung. Inpatient antibiotic escalation to cefepime, ertapenem, and meropenem resolved the positive cultures and fever, but the patient's respiratory function continued to decline, requiring intubation and extracorporeal membrane oxygenation. High-dose steroids and therapeutic plasma exchanges were initiated for suspected acute rejection. During the workup, a newly developed anti-A1 red blood cell antibody was identified. Despite supportive efforts, the patient died on POD 55, 14 days after symptomatic presentation. Conclusion: This case highlights the clinical significance of AMR in lung allografts, as well as the need to investigate both HLA and non-HLA antibody sources in pulmonary transplant rejection refractory to treatment. PMID- 30275792 TI - Repetitive Transcranial Magnetic Stimulation for Treatment of Depression in a Patient With Severe Traumatic Brain Injury. AB - Background: Traumatic brain injury (TBI) commonly presents with a constellation of findings, including physical, cognitive, and psychological disturbances. Traditionally, few options have been available for long-term management of mood symptoms for post-TBI patients who are refractory to medications. Repetitive transcranial magnetic stimulation (rTMS) is a promising alternative treatment. Case Report: A 37-year-old male with history of anxiety and bipolar depression incurred a TBI after a 60-foot fall. After his physical recovery, the patient had refractory depression. Eight months after the TBI event, he underwent a 6-week course of rTMS treatment and had a 70.8% improvement in mood symptoms by the end of the therapy as indicated by the Patient Health Questionnaire-9, transitioning from severe to mild depression according to the scoring system. Clinical correlation during the months following conclusion of rTMS therapy showed no signs of remission or adverse side effects. The patient remains stable and lives independently 1 year after treatment with mood-stabilizing medications. Conclusion: This case provides evidence for successful treatment of refractory depressive symptoms after severe TBI with the addition of rTMS to psychotherapy and mood-stabilizing medications, supporting the safety and tolerability of this novel therapeutic approach. Further studies are needed to validate the contribution of rTMS for management of mood symptoms in patients with TBI. PMID- 30275793 TI - Iatrogenic Spinal Epidural Hematoma in the Acute Postoperative Period. AB - Background: Spinal epidural hematomas (SEHs) are a rare but serious complication associated with spinal surgery, with an incidence estimated to be as high as 3%. Patients present with back pain and neurologic symptoms, with a typical onset time of several hours to days following surgery. Case Report: A 60-year-old female who underwent cervical spine surgery had negative intraoperative neuromonitoring and no apparent neurologic deficits of the upper extremities immediately postsurgery. On arrival in the postanesthesia care unit, the patient reported a loss of sensation in her lower extremities, prompting the anesthesiology resident to perform a focused neurologic examination. The patient demonstrated 0/5 motor strength in the lower extremities and total loss of sensation to touch and temperature up to the level of T10 bilaterally. She was returned to the operating room, and surgical exploration revealed a cervical SEH. Decompression yielded abrupt return of motor evoked potentials and improvement in somatosensory evoked potentials. Conclusion: As the primary clinician in the perioperative period, the anesthesiologist is ideally positioned to be the first to detect any deterioration in a patient's condition. Anesthesiologists should be cognizant of the potential for acute presentation of SEH so that it can be considered in the differential diagnosis. PMID- 30275794 TI - Beyond Beck's Triad: A Rare Cause of Cardiac Tamponade and Hemoptysis. AB - Background: Primary cardiac angiosarcoma (CAS) is a rare tumor with a dismal prognosis. Many patients present with noncardiac symptoms related to metastatic disease that could delay the diagnosis and deteriorate the outcome. Case Report: A 36-year-old male presented with hemoptysis. Initial imaging and biopsies were inconclusive, but a repeat transthoracic echocardiogram to evaluate the patient's pericardial effusion showed a mass inferior to the right atrium and invading the wall. Biopsy results from 3 different sites confirmed the diagnosis of CAS. However, the patient's course was complicated with respiratory failure that ultimately led to his death. Autopsy demonstrated CAS involving the full thickness of the right atrium and pericardial tissue, with a diffuse metastatic process involving the lung, brain, and stomach. Conclusion: The case highlights the importance of having an increased level of suspicion for cardiac malignancy among young patients presenting with noncardiac symptoms. PMID- 30275795 TI - Metastatic Renal Cell Carcinoma Presenting as a Bleeding Gastric Polyp. AB - Background: Renal cell carcinoma (RCC) is responsible for nearly 13,000 deaths in the United States every year, predominantly because of metastasis to other bodily organs. However, metastasis of RCC to the stomach occurs rarely; it presents as solitary or multiple polyps or as ulcers concerning for primary gastric carcinoma. Bleeding from metastasis to the stomach is a rare and underrecognized cause of gastrointestinal bleeding. We describe a case of gastrointestinal bleeding in an elderly female who was found to have a gastric polyp of RCC origin. Case Report: An 83-year-old female presented to our hospital for evaluation of an acute right basal ganglia hemorrhage after falling at her nursing home. Her hospital course was notable for melenic stool and anemia. Upper endoscopy revealed a single 40-mm pedunculated polyp and active bleeding on the lesser curvature of the stomach. Polypectomy and clipping were performed. Pathology was consistent with metastatic clear cell RCC. The patient's family declined a referral to oncology for evaluation of the newly diagnosed malignancy and opted for hospice care. Conclusion: This case illustrates the potential for metastatic RCC to involve the stomach and cause gastrointestinal bleeding and anemia. The case also illustrates the role of upper gastrointestinal endoscopy in diagnosing and treating metastatic causes of gastrointestinal bleeding. PMID- 30275796 TI - Trauma-Induced Conduction Disturbances. AB - Background: Electrical disturbances following blunt cardiac injuries are rare but can be caused by electrical or structural damage to the heart. We present the case of a patient who had conduction abnormalities following blunt traumatic injury that were incidentally detected on telemetry. Case Report: A 64-year-old female with no history of cardiac disease was brought to the emergency department after a motor vehicle collision that resulted in chest wall bruising. The patient was found to have L-spine fractures and was admitted for observation. During her hospitalization, the patient had multiple episodes of heart block. A temporary pacemaker was inserted because of the recurrent episodes, and a dual-chamber permanent pacemaker was placed on day 4 of her hospitalization. Conclusion: Heart block as a consequence of blunt cardiac injury is rare; however, it needs to be recognized as early as possible. Permanent pacemaker placement is usually indicated for patients with prolonged or recurrent episodes. PMID- 30275797 TI - Patellofemoral Arthroplasty. AB - Background: Patellofemoral arthritis is a common cause of anterior knee pain and limits flexion-related activities of daily living and exercise. While frequently present in bicompartmental and tricompartmental osteoarthritis, patellofemoral arthritis can occur in isolation. Patellofemoral arthroplasty as a treatment option is gaining in popularity, especially with new implant designs. We report a case in which new inlay implants were used to resurface the patellofemoral joint in a patient with contralateral compromise secondary to a previous below-knee amputation. Case Report: A 37-year-old female with a contralateral right below knee amputation and progressive left patellofemoral arthritis had failed multiple conservative treatment modalities. She underwent isolated patellofemoral arthroplasty using an inlay-designed implant. The patient was followed for 2 years postoperatively. She noticed an immediate increase in her knee range of motion and her pain scores improved. Two years postoperatively, she demonstrated drastic improvement in all outcome measures: International Knee Documentation Committee score (16.1 to 88.5), Lysholm Knee Scoring Scale (22 to 100), Knee Injury and Osteoarthritis Outcome Score (KOOS) Symptoms (7.14 to 96.43), KOOS Pain (2.78 to 100), KOOS Activities of Daily Living (0 to 100), KOOS Sports (0 to 100), and KOOS Quality of Life (12.5 to 93.75). Conclusion: Inlay patellofemoral arthroplasty is a valid treatment option for isolated patellofemoral arthritis. Successful results can be achieved with this procedure after failure of conservative measures in patients with limited or no evidence of tibiofemoral arthritis. PMID- 30275798 TI - Left Ventricular Aneurysm Presenting as Bidirectional Ventricular Tachycardia. AB - Background: Bidirectional ventricular tachycardia is a rare form of ventricular arrhythmia, characterized by a changing of the mean QRS axis of 180 degrees. Digitalis toxicity is the most common cause of bidirectional ventricular tachycardia; other causes include myocarditis, aconite toxicity, metastatic cardiac tumor, myocardial infarction, and cardiac channelopathies. Case Report: A 73-year-old male with hypertension and a pacemaker implanted for sick sinus syndrome presented with a complaint of substernal chest pressure for several days. He also stated he had had an episode of near syncope. The patient's physical examination was unremarkable; however, electrocardiogram demonstrated sustained bidirectional ventricular tachycardia. Echocardiogram showed severe anterior wall hypokinesis and an estimated ejection fraction of 35%, as well as an apical ventricular aneurysm. Electrophysiology study showed that the apical ventricular aneurysm was the site of the bidirectional arrhythmia. The patient was successfully treated with ventricular tachycardia ablation. Conclusion: This case is a unique example of a patient with bidirectional ventricular tachycardia originating from an apical left ventricular aneurysm that was treated successfully by ablation. PMID- 30275799 TI - Antibacterial and Antibiotic-Potentiating Activities of Thirteen Cameroonian Edible Plants against Gram-Negative Resistant Phenotypes. AB - This work was designed to investigate the antibacterial activities of methanol extracts from thirteen Cameroonian edible plants and their antibiotic potentiating effects against Gram-negative multidrug-resistant (MDR) phenotypes. The broth microdilution method was used to evaluate the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of the extracts, as well as their antibiotic-potentiating activities. The phytochemical screening of the extracts was carried out according to the standard methods. The results of phytochemical tests revealed the presence of sterols, polyphenols, and tannins in most of the tested extracts, with the other classes of secondary metabolites being selectively distributed. Tested extracts showed variable antibacterial activities with MIC values ranging from 64 to 1024 MUg/mL. However, some extracts were significantly active against certain bacterial strains: seeds extract of Theobroma cacao (64 MUg/mL) against Escherichia coli AG100Atet and Klebsiella pneumoniae K24, and the bark extract of Uapaca guineensis against E. coli ATCC 8739. The leaves extract of T. cacao displayed the best MBC values (256 MUg/mL) against E. aerogenes EA27. Some tested extracts included extracts from the leaves of T. cacao and P. vulgaris, and the seeds of D. edulis and barks A. indica has selectively improved (2- to 64-fold) the antibacterial activities of some of the tested antibiotics, chloramphenicol (CHL), tetracycline (TET), kanamycin (KAN), streptomycin (STR), and erythromycin (ERY), against more than 70% of tested MDR bacteria. The findings of this work showed that tested plant extracts and particularly those from T. cacao and Phaseolus vulgaris can be used alone or in combination with conventional antibiotics in the treatment of infections involving multiresistant bacteria. PMID- 30275800 TI - Parameters Influencing PET Imaging Features: A Phantom Study with Irregular and Heterogeneous Synthetic Lesions. AB - Aim: To evaluate reproducibility and stability of radiomic features as effects of the use of different volume segmentation methods and reconstruction settings. The potential of radiomics in really capturing the presence of heterogeneous tumor uptake and irregular shape was also investigated. Materials and Methods: An anthropomorphic phantom miming real clinical situations including synthetic lesions with irregular shape and nonuniform radiotracer uptake was used. 18F-FDG PET/CT measurements of the phantom were performed including 38 lesions of different shape, size, lesion-to-background ratio, and radiotracer uptake distribution. Different reconstruction parameters and segmentation methods were considered. COVs were calculated to quantify feature variations over the different reconstruction settings. Friedman test was applied to the values of the radiomic features obtained for the considered segmentation approaches. Two sets of test-retest measurement were acquired and the pairwise intraclass correlation coefficient was calculated. Fifty-eight morphological and statistical features were extracted from the segmented lesion volumes. A Mann-Whitney test was used to evaluate significant differences among each feature when calculated from heterogeneous versus homogeneous uptake. The significance of each radiomic feature in terms of capturing heterogeneity was evaluated also by testing correlation with gold standard indexes of heterogeneity and sphericity. Results: The choice of the segmentation method has a strong impact on the stability of radiomic features (less than 20% can be considered stable features). Reconstruction affects the estimate of radiomic features (only 26% are stable). Thirty-one radiomic features (53%) resulted to be reproducible, 11 of them are able to discriminate heterogeneity. Among these, we found a subset of 3 radiomic features strongly correlated with GS heterogeneity index that can be suggested as good features for retrospective evaluations.

AB - In this paper we report the synthesis of a new polyacrylate named poly(1,1' BP4MA) which is a derivate from 4-biphenylmethanol monomer. Poly(1,1'-BP4MA) was obtained by solution and bulk polymerization techniques to yield polymers with high molecular weight and high solubility. The study of the optical properties showed that poly(1,1'-BP4MA) is a fluorescent material with emission in the UV green region and it has similar quantum yield to tryptophan. PMID- 30275801 TI - Detecting GPC3-Expressing Hepatocellular Carcinoma with L5 Peptide-Guided Pretargeting Approach: In Vitro and In Vivo MR Imaging Experiments. AB - Objective: To investigate the potential of L5 peptide-guided pretargeting approach to identify GPC3-expressing hepatocellular carcinoma (HCC) using ultrasmall superparamagnetic iron oxide (USPIO) as the MR probe. Methods: Immunofluorescence with carboxyfluorescein- (FAM-) labeled L5 peptide was performed in HepG2 cells. Polyethylene glycol-modified USPIO (PEG-USPIO) and its conjugation with streptavidin (SA-PEG-USPIO) were synthesized, and their hydrodynamic diameters, zeta potential, T2 relaxivity, and cytotoxicity were measured. In vitro and in vivo two-step pretargeting MR imaging was performed on HepG2 cells and tumor-bearing mice after the administration of biotinylated L5 peptide (first step), followed by SA-PEG-USPIO (second step). Prussian blue staining was performed to assess iron deposition in tumors. Results: The high specificity of L5 peptide for GPC3 was demonstrated. Generation of SA-PEG-USPIO nanoparticles with good biocompatibility (an average hydrodynamic diameter of 35.97 nm and a zeta potential of -7.91 mV), superparamagnetism (R 2 = 0.1039 * 103 mM-1s-1), and low toxicity was achieved. The pretargeting group showed more enhancement than the nonpretargeting group both in vitro (60% vs 20%, P < 0.05) and in vivo (32% vs 6%, P < 0.001). Substantial iron deposition was only observed in HepG2 cells and tumors in the pretargeting group. Conclusion: L5 peptide guided, two-step pretargeting approach with USPIO as the MR imaging probe is a lucrative strategy to specifically identify GPC3-expressing HCC. PMID- 30275803 TI - Miscibility of poly(acrylic acid)/poly(methyl vinyl ketone) blend and in vitro application as drug carrier system. AB - A series of poly(acrylic acid)/poly(methyl vinyl ketone) (PAA/PMVK) blends with different compositions were prepared by the solvent casting method. The miscibility of this pair of polymers was investigated by differential scanning calorimetry(DSC), Fourier transform infra-red (FTIR) and X-Ray diffraction (XRD) techniques. An in-vitro cytotoxicity test of the drug-carrier system via MTT (3 (4,5-demethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay revealed no significant cytotoxic effects at concentrations up to 100 ug. ml-1. The STX/PAA 50 drug carrier systems were also prepared by solvent casting of solutions containing the sulfamethoxazole (STX) used as drug model and PAA/PMVK blend in N.N-dimethylformamide then crosslinked with acidified ethylene glycol. The release dynamic of STX from the prepared hydrogels was investigated in which the diffusion through the polymer matrix, the enhancement of the water solubility of STX, the influence of the initial drug concentration, the pH of the medium, and the effect of the degree of swelling of the polymer matrix on the release dynamic was evaluated. According to the total gastrointestinal transit time estimated by Belzer, the estimate distribution of STX released in the different organs indicated that the performance is obtained with the drug - carrier-system containing equal ratios of polymer and 10 wt% of STX (STX-10/PAA-50). PMID- 30275804 TI - Clinicopathological Characteristics of Urinary Bladder Tumors in Korean Patients 20 Years or Younger. AB - Background: To investigate the clinicopathological characteristics of urinary bladder tumors, a rare malignancy, in patients 20 years or younger. Methods: Using a retrospective chart review among patients who received bladder surgery at 2 institutions between July 1996 and January 2013, we analyzed the clinicopathological characteristics of urinary bladder tumors in 21 pediatric patients (male:female = 4.25:1.00; mean age, 12.1 years). Results: Pathology revealed 9 urothelial tumors, 6 rhabdomyosarcomas, 1 low-grade leiomyosarcoma, 1 large cell neuroendocrine carcinoma, 1 inflammatory myofibroblastic tumor, and 3 cases of chronic inflammation without tumors (including 1 xanthogranulomatous inflammation). Urothelial tumors (mean patient age, 16.0 years) were benign or low-grade; and only transurethral resection of the bladder tumor was necessary for treatment. Patients with rhabdomyosarcomas (mean age, 5 years) underwent radiotherapy (if unresectable) or transurethral resection of the bladder tumor (if resectable), after chemotherapy. Of these patients, 2 underwent radical cystectomy, with the remaining patients not receiving a cystectomy. With the exception of one patient, all patients are currently alive and recurrence-free. Conclusion: Urothelial tumors were the most commonly found pediatric bladder tumor, with embryonal rhabdomyosarcoma being the second most common. Urothelial tumors are common in relatively older age. Since urothelial tumors in children typically have a good prognosis and rarely recur, transurethral resection of the bladder tumor is the treatment of choice. Rhabdomyosarcomas are common in younger patients. Since rhabdomyosarcoma is generally chemosensitive, chemotherapy and radiotherapy are the treatment of choice for bladder preservation in these patients. PMID- 30275805 TI - Validity, Reliability and Responsiveness of the Korean Version of Quick Disabilities of the Arm, Shoulder, and Hand Questionnaire in Patients with Carpal Tunnel Syndrome. AB - Background: The Quick Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH) is one of the most widely used questionnaires for assessing functional ability of the patients with upper extremity diseases. Carpal tunnel syndrome (CTS) is the most common neuropathic disease in the upper extremities. The aim of this study was to verify the validity, reliability, and responsiveness of Korean version of QuickDASH questionnaire (K-QuickDASH) in the patients with CTS. Methods: In total, 83 subjects who underwent open carpal tunnel release (CTR) operation were selected. They fulfilled Korean version of Disabilities of the Arm, Shoulder and Hand questionnaire (K-DASH) and K-QuickDASH at two different time points: before and six months after the surgery. Both criterion related and construct validities were evaluated using Pearson's correlation coefficient and factor analysis. Internal consistency was estimated using Cronbach's alpha, and test-retest reliability was assessed to verify the reliability of K-QuickDASH using intraclass correlation coefficient (ICC). The standardized response mean and the effect size were analyzed to confirm the responsiveness of the K-QuickDASH in CTS patients. Results: Significant positive correlation was found between K-QuickDASH and K-DASH. All the questionnaire items were categorized into three factors. Acceptable internal consistency was confirmed in three categories of K-QuickDASH. A high test-retest reliability and responsiveness of K-QuickDASH were detected. Conclusion: K-QuickDASH in Korean patients with CTS was confirmed to have high degree of validity and reliability, and responsiveness after CTR. Therefore, the K-QuickDASH would be a good evaluation tool for evaluating clinical symptoms and determination of treatment outcomes in the patients with CTS. PMID- 30275807 TI - Burden of Disease Due to Secondhand Smoke among Korean Adults at Sub-National Level. AB - Background: Exposure to secondhand smoke (SHS) is one of the biggest health hazards. Quantifying the related burden of disease (BOD) is a powerful tool for making evidence-based policies. This study calculated the BOD due to SHS at sub national level using the most recent statistics of Korea. Methods: SHS related diseases were selected by the systematic review of previous studies. Population attributable fraction (PAF) was calculated by using the standard formula using prevalence of exposure derived from Community Health Survey (CHS) 2013. SHS burden was calculated by multiplying nonsmoker's disability adjusted life years (DALYs) with PAF of SHS. Results: SHS burden at sub-national level ranged between 460 DALYs in Cheonan to 5 DALYs in Pyeongtaek, Songtan region. Median of DALY was highest in districts of metropolitan cities and lowest in small towns and rural areas. Twelve out of fifteen regions with highest DALY per 1,000 were small towns and rural areas. Gender and age standardized DALY was highest in Seogwipo (west) in Jeju-do (1.66/1,000) and lowest in Dong-gu, Ulsan (0.17/1,000). Conclusion: There were substantial variations between regions according to BOD. Regional governments should implement policies according to specific situation in each region and regular monitoring should be done by calculating BOD. Big cities need to focus more on control of active and SHS prevalence. Resources in small towns and rural areas need to be allocated more towards implementation of screening programs, early diagnosis and treatment of diseases especially in the elderly population. PMID- 30275806 TI - The Infinity War: How to Cope with Carbapenem-resistant Enterobacteriaceae. AB - Carbapenem-resistant Enterobacteriaceae (CRE) are now spread worldwide. In Korea, the number of CRE isolation is rapidly increasing, and impending endemicity is a concern. To cope well with CRE, thorough infection control, such as active surveillance, early detection, strict contact precaution, cleaning the environment, and antibiotic stewardship is very important. Therapeutic options include polymyxin, tigecycline, fosfomycin or the combination of them with carbapenem, which is currently the mainstay of treatment. In addition, various combination regimens with new carbapenemase inhibitors such as avibactam, vaborbactam, or relebactam, and other classes of antimicrobials such as plazomicin and siderophore cephalosporin are in the process of evaluation. PMID- 30275808 TI - Outcomes after Arterial or Venous Reconstructions in Limb Salvage Surgery for Extremity Soft Tissue Sarcoma. AB - Background: Limb salvage surgery with vascular reconstruction is currently considered as the standard treatment for extremity soft tissue sarcoma (STS), showing equivalent oncologic outcome compared with amputation. In this retrospective study, the surgical and functional outcomes after arterial or venous reconstruction in limb salvage surgery for STS were analyzed. Methods: Consecutive patients who underwent vascular resection and reconstruction as part of limb salvage surgery for extremity STS from July 2009 to June 2015 were included in this study. Incidence of surgical complication, graft patency, and patients' functional outcome were reviewed. Results: During the study period, 14 arteries and 13 veins were reconstructed in 17 patients (artery only in 4, vein only in 3, artery and vein in 10). Autologous great saphenous vein (GSV) was the most commonly used vascular conduit in both arterial and venous reconstruction (78.6% and 77.0%). The patency of synthetic graft was significantly lower than that of the autologous vein conduit (log rank test, P = 0.001). Among 15 patients with tumors in lower extremity, 13 were ambulatory after limb salvage surgery. During median follow up of 23.3 months (interquartile range 39.9 months), 2 patients (11.7%) needed amputation of the initially salvaged limb due to local recurrence. Conclusion: Limb salvage surgery of soft tissue tumor combined with vascular reconstruction showed favorable functional outcome with good local control. Autologous vein conduit is preferred over synthetic graft both in arterial and venous reconstruction. PMID- 30275809 TI - Development of 17 polymorphic microsatellite loci from Jeju striped field mouse, Apodemus agrarius chejuensis (Rodentia: Muridae), by 454 pyrosequencing. AB - Background: The striped field mouse, Apodemus agrarius, is the most common mammal in Korea. Although microsatellite loci for the species have been identified from populations in southwestern China, amplification of those markers for Korean populations have been unsuccessful. The complicated taxonomy of Korean striped field mouse including populations on Jeju Island (A. a chejuensis) necessitates identification of additional molecular markers. Findings: We applied 454 pyrosequencing systems to develop a suite of microsatellite markers. Muscle tissue was harvested and sequenced from 30 Jeju striped field mouse specimens which yielded 12,165 reads with a mean length per read of 287 bp. From these reads, we identified 17 microsatellite loci for A. a. chejuensis and tested these new markers against samples of both A. a chejuensis and A. a coreae, the mainland taxon. All 17 loci were amplified successfully for both taxa. Of the total 17 loci, one locus failed to amplify for a population on Heuksan Island. The cross species transferability was also tested with the allied taxon, A. peninsulae and confirmed successful for 12 loci. Conclusions: These newly developed markers will benefit studies of genetic structure, evolution, and resolving taxonomic problems of striped field mice and allied taxa in Korea. PMID- 30275810 TI - Clinical and Immunological Aspects in Hashimoto's Thyroiditis. AB - We propose to establish the relationship between the clinical, functional and immunological parameters in a cohort of women with Hashimoto's thyroiditis. The study included 68 patients between 19 and 70 who were hospitalized for two years in the Endocrinology Clinic of the Hospital in Timisoara. The thyroidal dimensions and the aspects of the thyroidal stroma were shown by echography examinations. The functional parameters like the serum TSH and free T4 concentrations were determined by chemiluminescent methods. The immunological investigations (antithyroglobulin and antiperoxidase antibodies) were performed by the ELISA method. Comparisons were performed by the t test and the Pearson correlation analysis. The correlation between the aspects of thyroidal stroma and thyroid function revealed hypothyroidism in most cases with moderate (++) or severe (+++) echogenity. Another researched aspect was that of correlation of the serum levels of TSH with the thyroidal dimension. The following correlations were obtained: r= - 0.14 in patients with clinical hypothyroidism and r= - 0.3055 in those with subclinical hypothyroidism. The Pearson coefficients for the level of TSH in um and those of the antiperoxidase antibodies, according to clinical and functional categories, revealed the following results: r= - 0.1580 in patients with clinical hypothyroidism and r= - 0.1961 in those with subclinical hypothyroidism. Patients with clinical hypothroidism have significant higher serum level of TSH as compared with those of the patients with subclinical hypothyroidism (p=0.0001). We established a relation between the severe hypoechogenity and hypothyroidism status in patients with positive serum antibodies (r= 0.5695).

PMID- 30275814 TI - Low Prevalence of Hepatitis C Virus Genotype -1b in Chronic Liver Disease Patients in India. AB - Background: The Hepatitis C Virus (HCV) genome shows significant heterogeneity due to a high rate of mutatio; this has a potential bearing on the outcome of interferon therapy. Genotype-1b is known to be less responsive to interferon. We studied the spectrum of HCV genotypes in chronic liver disease (CLD) patients in India. Material and Methods: HCV RNA was extracted from the serum of 44 randomly selected cases of HCV-related CLD, proven by liver biopsy, (mean age of patients 40+/-15 yr., cirrhotic: 32%) and RT PCR was carried out. The amplicon of 240 bp (second nested PCR) was hybridized to the probes (type specific) coated on to a nitrocellulose membrane. Following this, streptavidin, labeled with alkaline phosphatase, was added to bind with biotinylated hybrid, which with chromogen type-specific band formation resulted. Patients were classified on the occurrence of one (Group I), two (Group II) or multiple genotypes (Group III). Results: Genotypes 1 and 3 were the commonest genotypes, followed by type 2 and the rare genotype 4b in a lone patient. Genotype 1 was seen in 39% (1a 23%, and 1b 16%) while genotype 3 in 45% (3a 23% and 3b 7%) patients. Eighty percent (35 of 44) patients had the single genotype (Group I, mean age 46 +/- 8 yr.), 14% had two genotypes (Group II, mean age 36 +/- 16 yr.) and the remaining (Group III, mean age 22 +/- 9 yr.) had multiple genotypes. Serum ALT levels in these three groups of patients were 117 +/- 92, 85 +/- 45 and 49 +/- 7 IU/L respectively. Conclusions: Genotypes 1 and 3 are common in India, with subtype 1b not so common,A unique genotype 4 b was detected in one patient,Indian patients have the possibility of good antiviral response to interferon therapy in chronic HCV infection.

AB - Sensory axon T-like branching (bifurcation) in neurons from dorsal root ganglia and cranial sensory ganglia depends on the molecular signaling cascade involving the secreted factor C-type natriuretic peptide, the natriuretic peptide receptor guanylyl cyclase B (GC-B; also known as Npr2) and cGMP-dependent protein kinase I (cGKI, also known as PKGI). The bifurcation of cranial nerves is suggested to be important for information processing by second-order neurons in the hindbrain or spinal cord. Indeed, mice with a spontaneous GC-B loss of function mutation (Npr2cn/cn ) display an impaired bifurcation of auditory nerve (AN) fibers. However, these mice did not show any obvious sign of impaired basal hearing. Here, we demonstrate that mice with a targeted inactivation of the GC-B gene (Npr2 lacZ/lacZ , GC-B KO mice) show an elevation of audiometric thresholds. In the inner ear, the cochlear hair cells in GC-B KO mice were nevertheless similar to those from wild type mice, justified by the typical expression of functionally relevant marker proteins. However, efferent cholinergic feedback to inner and outer hair cells was reduced in GC-B KO mice, linked to very likely reduced rapid efferent feedback. Sound-evoked AN responses of GC-B KO mice were elevated, a feature that is known to occur when the efferent axo-dendritic feedback on AN is compromised. Furthermore, late sound-evoked brainstem responses were significantly delayed in GC-B KO mice. This delay in sound response was accompanied by a weaker sensitivity of the auditory steady state response to amplitude-modulated sound stimuli. Finally, the acoustic startle response (ASR) - one of the fastest auditory responses - and the prepulse inhibition of the ASR indicated significant changes in temporal precision of auditory processing. These findings suggest that GC-B-controlled axon bifurcation of spiral ganglion neurons is important for proper activation of second-order neurons in the hindbrain and is a prerequisite for proper temporal auditory processing likely by establishing accurate efferent top-down control circuits. These data hypothesize that the bifurcation pattern of cranial nerves is important to shape spatial and temporal information processing for sensory feedback control. PMID- 30275819 TI - Neolignans isolated from twigs of Nectandra leucantha Ness & Mart (Lauraceae) displayed in vitro antileishmanial activity. AB - Background: The therapeutic arsenal for the treatment of Leishmaniasis is limited and includes toxic compounds (antimonials, amphotericin B, pentamidine and miltefosine). Given these aspects, the search for new compounds based on floristic biodiversity is crucial. In the present work, we report the isolation, characterization and antileishmanial activity of six related neolignans (1-6) of bioactive extract from Nectandra leucantha (Lauraceae) twigs. Methods: Dried and powdered twigs of N. leucantha were exhaustively extracted using n-hexane. The crude extract was dereplicated by HPLC/HRESIMS and subjected to column chromatography to yield pure compounds 1-6. Their chemical structures were identified via NMR and comparison of obtained data with those previously published in the literature. Biological assays of compounds 1-6 and their respective monomers (eugenol and methyleugenol) were performed using promastigote and amastigote forms of Leishmania (L.) infantum. Results: Dereplication procedures followed by chemical characterization of isolated compounds by NMR enabled the identification of related neolignans 1-6. Neolignans 2, 4 and 6 showed potential against amastigote forms of L. (L.) infantum (EC50 values of 57.9, 67.7 and 13.7 MUM, respectively), while compounds 1 and 3 were inactive. As neolignans 2-4 are chemically related, it may be suggested that the presence of the methoxyl group at C4 constitutes an important structural aspect to increase antileishmanial potential against amastigote forms. Compound 6, which consists of a methylated derivative of compound 5 (inactive) showed antileishmanial activity similar to that of the standard drug miltefosine (EC50 = 16.9 MUM) but with reduced toxicity (SI = 14.6 and 7.2, respectively). Finally, two related monomers, eugenol and methyleugenol, were also tested and did not display activity, suggesting that the formation of dimeric compounds by oxidative coupling is crucial for antiparasitic activity of dimeric compounds 2, 4 and 6. Conclusion: This study highlights compound 6 against L. (L.) infantum amastigotes as a scaffold for future design of new compounds for drug treatment of visceral leishmaniasis. PMID- 30275820 TI - An Automated Approach for Epilepsy Detection Based on Tunable Q-Wavelet and Firefly Feature Selection Algorithm. AB - Detection of epileptic seizures using an electroencephalogram (EEG) signals is a challenging task that requires a high level of skilled neurophysiologists. Therefore, computer-aided detection provides an asset to the neurophysiologist in interpreting the EEG. This paper introduces a novel approach to recognize and classify the epileptic seizure and seizure-free EEG signals automatically by an intelligent computer-aided method. Moreover, the prediction of the preictal phase of the epilepsy is proposed to assist the neurophysiologist in the clinic. The proposed method presents two perspectives for the EEG signal processing to detect and classify the seizures and seizure-free signals. The first perspectives consider the EEG signal as a nonlinear time series. A tunable Q-wavelet is applied to decompose the signal into smaller segments called subbands. Then a chaotic, statistical, and power spectrum features sets are extracted from each subband. The second perspectives process the EEG signal as an image; hence the gray-level co-occurrence matrix is determined from the image to obtain the textures of contrast, correlation, energy, and homogeneity. Due to a large number of features obtained, a feature selection algorithm based on firefly optimization was applied. The firefly optimization reduces the original set of features and generates a reduced compact set. A random forest classifier is trained for the classification and prediction of the seizures and seizure-free signals. Afterward, a dataset from the University of Bonn, Germany, is used for benchmarking and evaluation. The proposed approach provided a significant result compared with other recent work regarding accuracy, recall, specificity, F measure, and Matthew's correlation coefficient.

PMID- 30275822 TI - Repulsive Environment Attenuation during Adult Mouse Optic Nerve Regeneration. AB - The regenerative capacity of CNS tracts has ever been a great hurdle to regenerative medicine. Although recent studies have described strategies to stimulate retinal ganglion cells (RGCs) to regenerate axons through the optic nerve, it still remains to be elucidated how these therapies modulate the inhibitory environment of CNS. Thus, the present work investigated the environmental content of the repulsive axon guidance cues, such as Sema3D and its receptors, myelin debris, and astrogliosis, within the regenerating optic nerve of mice submitted to intraocular inflammation + cAMP combined to conditional deletion of PTEN in RGC after optic nerve crush. We show here that treatment was able to promote axonal regeneration through the optic nerve and reach visual targets at twelve weeks after injury. The Regenerating group presented reduced MBP levels, increased microglia/macrophage number, and reduced astrocyte reactivity and CSPG content following optic nerve injury. In addition, Sema3D content and its receptors are reduced in the Regenerating group. Together, our results provide, for the first time, evidence that several regenerative repulsive signals are reduced in regenerating optic nerve fibers following a combined therapy. Therefore, the treatment used made the CNS microenvironment more permissive to regeneration. PMID- 30275823 TI - Anatomical and Functional MRI Changes after One Year of Auditory Rehabilitation with Hearing Aids. AB - Hearing aids (HAs) are an effective strategy for auditory rehabilitation in patients with peripheral hearing deficits. Yet, the neurophysiological mechanisms behind HA use are still unclear. Thus far, most studies have focused on changes in the auditory system, although it is expected that hearing deficits affect a number of cognitive systems, notably speech. In the present study, we used audiometric evaluations in 14 patients with bilateral hearing loss before and after one year of continuous HA use and functional magnetic resonance imaging (fMRI) and cortical thickness analysis in 12 and 10 of them compared with a normal hearing control group. Prior to HA fitting, fMRI activity was found reduced in the auditory and language systems and increased in visual and frontal areas, expanding to multimodal integration cortices, such as the superior temporal gyrus, intraparietal sulcus, and insula. One year after rehabilitation with HA, significant audiometric improvement was observed, especially in free field Speech Reception Threshold (SRT) test and functional gain, a measure of HA efficiency. HA use increased fMRI activity in the auditory and language cortices and multimodal integration areas. Individual fMRI signal changes from all these areas were positively correlated with individual SRT changes. Before rehabilitation, cortical thickness was increased in parts of the prefrontal cortex, precuneus, fusiform gyrus, and middle temporal gyrus. It was reduced in the insula, supramarginal gyrus, medial temporal gyrus, occipital cortex, posterior cingulate cortex, and claustrum. After HA use, increased cortical thickness was observed in multimodal integration regions, particularly the very caudal end of the superior temporal sulcus, the angular gyrus, and the inferior parietal gyrus/superior temporal gyrus/insula. Our data provide the first evidence that one year of HA use is related to functional and anatomical brain changes, notably in auditory and language systems, extending to multimodal cortices. PMID- 30275824 TI - Risk Factors Associated with the Occurrence of Autoimmune Diseases in Adult Coeliac Patients. AB - Objectives: Autoimmune diseases (AD) may be associated with coeliac disease (CD), but specific risk factors have been poorly investigated. The aim of this study was to assess the spectrum of AD and its specific risk factors associated in a series of adult coeliac patients. Materials and Methods: We performed a single center case-control study including adult newly diagnosed CD patients. To evaluate the risk factors of the association between AD and CD, 341 coeliac patients included were categorized on the basis of AD presence: 91 cases with at least one AD and 250 controls without AD were compared for clinical, serological, and histological features. Eighty-seven cases were age-gender-matched with 87 controls. Results: Among 341 CD patients, 26.6% of CD patients had at least one AD. Endocrine and dermatological diseases were the most prevalent AD encountered: autoimmune thyroiditis was present in 48.4% of cases, psoriasis in 17.6%, and type I diabetes and dermatitis herpetiformis in 11%, respectively. At logistic regression, factors associated with AD were a positive 1st-degree family history of AD (OR 3.7, 95% CI 1.93-7), a body mass index >= 25 kg/m2 at CD diagnosis (OR 2.95%, CI 1.1-3.8), and long standing presentation signs/symptoms before CD diagnosis (>10 years) (OR 2.1, 95% CI 1.1-3.7). Analysis on age-gender-matched patients confirmed these results. Conclusions: CD patients with family history of AD, overweight at CD diagnosis, and a delay of CD diagnosis had an increased risk of having another AD. The benefit of CD screening in these specific subsets of patients with AD awaits further investigation. PMID- 30275825 TI - The Application of a Macroinvertebrate Indicator in Afrotropical Regions for Pesticide Pollution. AB - Many biotic integrity indices are not able to isolate community effects due to pesticide exposure as the communities also respond to other anthropogenic and natural stressors. A macroinvertebrate trait bioindicator system that is pesticide specific was therefore developed to overcome these challenges. This system, called SPEAR (SPEcies At Risk), was applied in South Africa as an indicator to link known pesticide catchment usage to changes in the macroinvertebrate community, especially when analytical methods are inconclusive. In addition, the SPEARsalinity index within the SPEAR suite of tools was also evaluated for its effectiveness in South Africa. The results indicated that all of the sites have either been exposed to the same pesticide pressure or not been exposed to pesticides as the SPEAR results were similar when compared to the pesticide intensity. The interaction with other factors like nutrients or salinity was likely a factor that confounded the SPEARpesticides indicator.

AB - Although quite a few polycystic ovary syndrome (PCOS) patients suffering from metabolic syndrome (MS) have been reported in previous studies, no reliable and early diagnostic biomarkers for MS in PCOS patients have yet been identified. To identify early and reliable diagnostic biomarkers for MS in Chinese women with PCOS, a total of 401 patients (200 PCOS patients and 201 controls) were enrolled in our present study. All of the subjects were examined for anthropometric (weight, waist circumference, blood pressure, etc.) and biochemical (fasting glucose, serum lipid indices, total testosterone, etc.) parameters. Our results showed that the prevalence of MS in the PCOS patients (20.50%) was 6.8-fold higher (P < 0.05) than that in the controls (2.99%). Nearly 71.0% of the PCOS patients had at least one component of MS, of which dyslipidemia was the most prevalent. Furthermore, within the PCOS group, the prevalence of MS increased with increasing age and body mass index (BMI). Logistic analysis indicated that BMI, triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), hypertension, and fasting glucose were significantly associated with the presence of MS in PCOS patients. Analysis of the ability of the potential diagnostic biomarkers to indicate MS in PCOS patients showed that the PPV, NPV, specificity, sensitivity, and Youden's index for waist circumference (WC) coupled with HDL-C were 59.68%, 97.10%, 84.28%, 90.24%, and 74.52, respectively, and those for WC coupled with TG were 93.33%, 92.35%, 98.74%, 68.29%, and 67.03%, respectively. ROC curve analysis showed that the areas under the ROC curves (AUCs) for WC coupled with HDL-C and for WC coupled with TG were 0.882 and 0.901, respectively. Our present study demonstrates that WC coupled with either HDL-C or TG can be used as a relatively early and reliable diagnostic biomarker for MS in Chinese PCOS patients.

AB - Background: Diagnosing polycystic ovary syndrome (PCOS) is based on ovulatory dysfunction, ovarian ultrasound data, and androgen excess. Total testosterone is frequently used to identify androgen excess, but testosterone is mainly bound to sex hormone-binding globulin (SHBG) and albumin. Only 1-2% of nonprotein-bound testosterone (so-called free testosterone) is biologically active and responsible for androgen action. Moreover, automated immunoassays which are frequently used for female testosterone measurements are inaccurate. Objective: To assess the clinical usefulness of liquid chromatography-tandem mass spectrometry measured testosterone and calculated free testosterone in subfertile women attending a fertility clinic with oligomenorrhea and suspected PCOS. Methods: Hormonal and metabolic parameters were evaluated, and ovarian ultrasound was performed. Total testosterone was measured by liquid chromatography-tandem mass spectrometry. Free testosterone was calculated from total testosterone and SHBG. Results: Sixty-six women were included in the study. Total testosterone was associated with ovarian volume and antral follicle count but not with metabolic parameters. However, SHBG and calculated free testosterone were associated with both ovarian ultrasound and metabolic parameters, such as BMI and insulin resistance. Conclusions: Assessing SHBG and free testosterone is important in evaluating androgen excess in subfertile women with ovulatory dysfunction and suspected PCOS, as it reflects both ovarian and metabolic disturbances. PMID- 30275831 TI - Association between the Anatomy of the Mandibular Canal and Facial Types: A Cone Beam Computed Tomography Analysis. AB - We evaluated the anatomical variations of the mandibular canal associated with various facial types, age, sex, and side of the face studied. We analyzed 348 hemimandibles in subjects without a history of trauma, lesions in the lower arch, or orthognathic or repair surgery in the posterior mandible. Facial type was determined using the VERT index. The canal path was classified as Type 1 (a large, single structure passing very close to the root tips); Type 2 (a canal passing closest to the mandibular base); and Type 3 (a canal present in the posterior mandibular region, with a lower canal running through the mandibular branch, reaching the anterior region). Bifid canals (type 3) were classified into four categories according to the course and number of mandibular canals. The brachyfacial and mesofacial types presented a Type 1 canal in 95.5% (n=166) of subjects, in dolichofacial types, 68.2% (n=45) presented a Type 2 canal, while in the mesofacial type, a lower prevalence of the bifid mandibular canal was observed (13.0%, n=23) than in the other facial types. The bifid canal showed significant association with facial type only (p < 0.05), but no significant association was observed with the anterior loop type (p > 0.05). Facial type is significantly associated with the path and morphological variations of the mandibular canal, independently of the side of the face studied, age, and sex. PMID- 30275832 TI - Shaping Ability of Superelastic and Controlled Memory Nickel-Titanium File Systems: An In Vitro Study. AB - Improvements in the thermomechanical processing procedures of NiTi wires have led to the development of new NiTi instruments that compose mainly of martensite crystals, making the wire stable at clinical condition. This study aimed at comparing the shaping ability of two rotary nickel-titanium systems manufactured from different NiTi wires. Twenty simulated root canals each with a curvature of 35 degrees in resin blocks were divided into two groups of 10 canals each. Canals in the first group were prepared with superelastic F360 instruments (Gebr. Brasseler, Germany) while canals in the second group were prepared using controlled memory HyFlex(r)CMTM instruments (Coltene Whaledent, Switzerland). Images were taken before canal preparation and after the use of each instrument. The assessment of the canal shapes was accomplished with a computer image analysis program. Data were statistically analyzed using SPSS program. Within the limitation of this in vitro study, HyFlex(r)CMTM instruments remained better centered in the apical third of the canals. In most canal segments, no significant differences were observed between either system in the amount of material removed. Both systems were comparable to each other in regards to their ability to enlarge root canal in the same way without procedural errors. PMID- 30275833 TI - Selective Preconcentration of Gold from Ore Samples. AB - A simple and selective method has been developed for preconcentration of gold in ore samples. The method is based on use of N, N-diethyl-N'-benzoylthiourea (DEBT) as selective chelating agent and Amberlite XAD-16 as solid sorbent. Sorption behavior of gold with DEBT impregnated resin under optimized conditions has been studied in batch process. The gold ion capacity of the impregnated resin is calculated as 33.48 mg g-1 resin (0.17 mmol g-1 resin). The selective preconcentration of metal was examined using gold chelates prepared in column process under optimized conditions: pH, flow rate, volume of sample solution, nature of eluent, flow rate, and volume of eluent. Under optimum conditions, gold ions at the concentration of 0.015 MUg mL-1 with a preconcentration factor of 6.7 have been determined by flame atomic absorption spectrometry (FAAS). The accuracy of the proposed method was validated by the analysis of a Cu-ore (semi-certified) supplied by CMC (Cyprus Mining Company, North Cyprus) and a certified reference material, Gold Ore (MA-1b Canmet-MMSL). Satisfactory results were obtained with a RSD of 7.6%. The highly selective proposed method does not require any interference elimination process. PMID- 30275834 TI - Toughening of Poly(L-lactide) with Blends of Poly(epsilon-caprolactone-co-L lactide) in the Presence of Chain Extender. AB - A poly(epsilon-caprolactone-co-L-lactide) copolyester was synthesized and employed to toughen poly(L-lactide) (PLLA) by reactive melt blending in the presence of an epoxy-based chain extender. The effects of chain extension reaction and copolyester content on properties of PLLA-based blends were studied. The chain extension reaction reduced crystallinity and melt flow index of PLLA/copolyester blends. Meanwhile the copolyester blending improved the crystallinities of the chain-extended PLLA up to 20 wt% copolyester. The phase compatibility between PLLA matrix and dispersed copolyester phases was enhanced by the chain extension reaction. The impact strength of chain-extended PLLA increased with the contents of copolyester and chain extender. PMID- 30275835 TI - Nasal Carriage of Methicillin-Resistant Staphylococcus aureus among Health Care Workers in Tertiary and Regional Hospitals in Dar es Salam, Tanzania. AB - Methicillin-resistant Staphylococcus aureus (MRSA) among health care workers (HCWs) increases the risk of spreading the organism in hospital settings. A cross sectional study was conducted between June and October 2016 among HCWs in tertiary and regional hospitals in Dar es Salaam, Tanzania, to determine the MRSA nasal carriage rate. Nasal swabs were collected from HCWs and cultured on mannitol salt agar. S. aureus was identified based on colonial morphology, Gram staining, catalase, coagulase, and DNase test results. MRSA was detected using the cefoxitin disk. Among 379 HCWs enrolled, 157/379 (41.4%) were colonized with S. aureus, of whom 59 (37.6%) were MRSA carriers giving an overall prevalence of 59/379 (15.6%). MRSA carriage was high among HCWs in Temeke (56.9%) and Amana (37.5%) regional hospitals. A high proportion of MRSA carriage was detected among nurses (35, 45.5%). MRSA isolates showed high resistance toward kanamycin (83.7%), gentamicin (83.1%), ciprofloxacin (71.2%), and trimethoprim sulphamethoxazole (46.8%) compared to methicillin-sensitive S. aureus isolates (p <= 0.001). In conclusion, we found a high nasal carriage of MRSA and resistance to commonly prescribed antimicrobial agents among HCWs. Implementation of infection control measures including contact precautions, urgent reporting of MRSA laboratory results, and routine MRSA screening of HCWs is highly needed to reduce MRSA spreading. PMID- 30275836 TI - Haploidentical Stem Cell Transplantation: A Gateway to Infrequent Availability of HLA-Matched Related Donors. AB - Haploidentical stem cell transplantation provides a plausible alternative for the patients when a fully matched donor is unavailable. Historically, the decision of considering haploidentical transplant has remained elusive; however, with the recent advances, the consideration of haploidentical grafts as a treatment option has become more apparent for both allografting for diseases and engraftment failure. We are reporting here an anecdotal case of a successful haploidentical engraftment in a patient with the prior graft failure of an HLA-matched related donor. Since the patient was severely alloimmunized, desensitization protocol was utilized before the haploidentical transplant, and the patient after 8 months of her second allogeneic transplantation is doing great with successful engraftment, no relapse, and no graft-versus-host disease (GVHD). Numerous reports pertinent to haploidentical graft have shown favorable outcomes in the graft placement, a decline in the rate of GVHD, and an improvement in the morbidity and mortality in affected individuals. Based on the current reports, haploidentical transplantation might be more feasible and has meaningful implications in the situations where matched donors are infrequent. PMID- 30275837 TI - Focal Adhesion Kinase and ROCK Signaling Are Switch-Like Regulators of Human Adipose Stem Cell Differentiation towards Osteogenic and Adipogenic Lineages. AB - Adipose tissue is an attractive stem cell source for soft and bone tissue engineering applications and stem cell therapies. The adipose-derived stromal/stem cells (ASCs) have a multilineage differentiation capacity that is regulated through extracellular signals. The cellular events related to cell adhesion and cytoskeleton have been suggested as central regulators of differentiation fate decision. However, the detailed knowledge of these molecular mechanisms in human ASCs remains limited. This study examined the significance of focal adhesion kinase (FAK), Rho-Rho-associated protein kinase (Rho-ROCK), and their downstream target extracellular signal-regulated kinase 1/2 (ERK1/2) on hASCs differentiation towards osteoblasts and adipocytes. Analyses of osteogenic markers RUNX2A, alkaline phosphatase, and matrix mineralization revealed an essential role of active FAK, ROCK, and ERK1/2 signaling for the osteogenesis of hASCs. Inhibition of these kinases with specific small molecule inhibitors diminished osteogenesis, while inhibition of FAK and ROCK activity led to elevation of adipogenic marker genes AP2 and LEP and lipid accumulation implicating adipogenesis. This denotes to a switch-like function of FAK and ROCK signaling in the osteogenic and adipogenic fates of hASCs. On the contrary, inhibition of ERK1/2 kinase activity deceased adipogenic differentiation, indicating that activation of ERK signaling is required for both adipogenic and osteogenic potential. Our findings highlight the reciprocal role of cell adhesion mechanisms and actin dynamics in regulation of hASC lineage commitment. This study enhances the knowledge of molecular mechanisms dictating hASC differentiation and thus opens possibilities for more efficient control of hASC differentiation. PMID- 30275838 TI - Genome-Wide DNA Methylation Analysis during Osteogenic Differentiation of Human Bone Marrow Mesenchymal Stem Cells. AB - Bone marrow mesenchymal stem cells (BMSCs) nowadays are regarded as promising candidates in cell-based therapy for the regeneration of damaged bone tissues that are either incurable or intractable due to the insufficiency of current therapies. Recent studies suggest that BMSCs differentiate into osteoblasts, and that this differentiation is regulated by some specific patterns of epigenetic modifications, such as DNA methylation. However, the potential role of DNA methylation modification in BMSC osteogenic differentiation is unclear. In this study, we performed a genome-wide study of DNA methylation between the noninduced and induced osteogenic differentiation of BMSCs at day 7. We found that the majority of cytosines in a CpG context were methylated in induced BMSCs. Our results also revealed that, along with the induced osteogenic differentiation in BMSCs, the average genomic methylation levels and CpG methylation in transcriptional factor regions (TFs) were increased, the CpG methylation level of various genomic elements was mainly in the medium-high methylation section, and CpG methylation levels in the repeat element had highly methylated levels. The GO analysis of differentially methylated region- (DMR-) associated genes (DMGs) showed that GO terms, including cytoskeletal protein binding (included in Molecular Function GO terms), skeletal development (included in Biological Process GO terms), mesenchymal cell differentiation (included in Biological Process GO terms), and stem cell differentiation (included in Biological Process), were enriched in the hypermethylated DMGs. Then, the KEGG analysis results showed that the WNT pathway, inositol phosphate metabolism pathway, and cocaine addiction pathway were more correlative with the DMRs during the induced osteogenic differentiation in BMSCs. In conclusion, this study revealed the difference of methylated levels during the noninduced and induced osteogenic differentiation of BMSCs and provided useful information for future works to characterize the important function of epigenetic mechanisms on BMSCs' differentiation. PMID- 30275841 TI - Assessment of Diarrhea and Its Associated Factors in Under-Five Children among Open Defecation and Open Defecation-Free Rural Settings of Dangla District, Northwest Ethiopia. AB - Background: Open defecation (OD) is a widespread problem in the developing world. This practice facilitates the transmission of diarrheal diseases. In Ethiopia, still the national open defecation rate in 2014 was 34.1% (37.9% in rural and 8.7% in urban). Objective: To assess diarrheal morbidity in under-five children and its associated factors in Dangla district, Northwest Ethiopia, 2016. Methods: A community-based comparative cross-sectional study design with a multistage random sampling technique was applied. The total sample size was 550 (275 ODF and 275 OD). Descriptive and inferential statistics were done. Results: A total of 525 participants were interviewed making the response rate 95.45%. The prevalence of diarrhea was 9.9% in ODF and 36.1% in OD kebeles. In ODF kebeles, child immunization (AOR = 0.037; 95% CI: 0.006-0.243), latrine presence (AOR = 0.036; 0.006-0.233), water shortage (AOR = 8.756; 95% CI: 1.130-67.831), and solid waste disposal (AOR = 0.143; 95% CI: 0.020-0.998) have statistically significant association with diarrhea occurrence. While in OD kebeles child immunization (AOR = 0.032; 95 CI: 0.008-0.123), water access of 7.5-15 liters/day (AOR = 0.029; 95% CI: 0.006-0.152), water shortage (AOR = 18.478; 95% CI: 4.692-72.760), and proper solid waste disposal (AOR = 0.023; 95% CI: 0.005-0.117) have significant association with diarrhea occurrence. Conclusions: The overall prevalence of under-five diarrhea was low in ODF kebeles as compared with OD kebeles. The study showed that child immunization, latrine presence, water shortage in household, and solid waste disposal practices had statistically significant association with diarrhea occurrence in ODF kebeles, while water access at the individual level, water shortage in household, child immunization, and solid waste disposal have statistically significant association with diarrhea occurrence in OD kebeles. Integrated efforts are needed from the Ministry of Health together with line ministries and developmental partners in improving latrine utilization at household level, water shortage in households, and solid waste disposal practices. PMID- 30275840 TI - Prevalence of Human Bocavirus in Africa and Other Developing Countries between 2005 and 2016: A Potential Emerging Viral Pathogen for Diarrhea. AB - Background: Human Bocavirus (HBoV) is an emerging virus discovered in 2005 from individuals suffering gastroenteritis and respiratory tract infections. Numerous studies related to the epidemiology and pathogenesis of HBoV have been conducted worldwide. This review reports on HBoV studies in individuals with acute gastroenteritis, with and without respiratory tract infections in Africa between 2005 and 2016. Material and Method: The search engines of PubMed, Google Scholar, and Embase database for published articles of HBoV were used to obtain data between 2005 and 2016. The search words included were as follows: studies performed in Africa or/other developing countries or/worldwide; studies for the detection of HBoV in patients with/without diarrhea and respiratory tract infection; studies using standardized laboratory techniques for detection. Results: The search yielded a total of 756 publications with 70 studies meeting the inclusion criteria. Studies included children and individuals of all age groups. HBoV prevalence in Africa was 13% in individuals suffering gastroenteritis with/without respiratory tract infection. Conclusion: Reports suggest that HBoV infections are increasingly being recognized worldwide. Therefore, surveillance of individuals suffering from infections in Africa is required to monitor the prevalence of HBoV and help understand the role of HBoV in individuals suffering from gastroenteritis with/without respiratory tract infection. PMID- 30275842 TI - Are Shiftwork and Indoor Work Related to D3 Vitamin Deficiency? A Systematic Review of Current Evidences. AB - Background: Reported cases of vitamin D3 deficiency have been increasing in incidence worldwide. Although there is a lack of consensus relating to optimal levels of vitamin D, generally serum 25-(OH)D concentrations lower than 50 nmol/L (20 ng/mL) are at least considered to be detrimental to bone health. Aim: Aim of this systematic review is to investigate if occupations, and specifically shiftworking and indoor working, may be considered as possible contributors to the increased incidence of vitamin D3 deficiency in industrialized nations. Materials and Methods: Systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement using PubMed, Scopus, and ISI Web of Knowledge databases. Results: Overall 90 papers were found, 23 articles through PubMed, 30 through Scopus, and 37 through ISI Web of Knowledge. Successively, 46 duplicates and 34 articles that did not respect the inclusion criteria were excluded. Finally 10 articles were selected: 9 cross sectional studies and 1 systematic review. Results of the studies included revealed that certain occupations are either suffering from, or have a predilection to suffer from, a deficiency of this vitamin. Shiftworkers and indoor workers are consistently reported as being the occupational group most likely to suffer from a deficiency of vitamin D3. It would appear prudent to investigate the potential of providing nutritional education to workers in addition to including preventative measures in the workplace. PMID- 30275839 TI - Bioprocessing of Mesenchymal Stem Cells and Their Derivatives: Toward Cell-Free Therapeutics. AB - Mesenchymal stem cells (MSCs) have attracted tremendous research interest due to their ability to repair tissues and reduce inflammation when implanted into a damaged or diseased site. These therapeutic effects have been largely attributed to the collection of biomolecules they secrete (i.e., their secretome). Recent studies have provided evidence that similar effects may be produced by utilizing only the secretome fraction containing extracellular vesicles (EVs). EVs are cell derived, membrane-bound vesicles that contain various biomolecules. Due to their small size and relative mobility, they provide a stable mechanism to deliver biomolecules (i.e., biological signals) throughout an organism. The use of the MSC secretome, or its components, has advantages over the implantation of the MSCs themselves: (i) signals can be bioengineered and scaled to specific dosages, and (ii) the nonliving nature of the secretome enables it to be efficiently stored and transported. However, since the composition and therapeutic benefit of the secretome can be influenced by cell source, culture conditions, isolation methods, and storage conditions, there is a need for standardization of bioprocessing parameters. This review focuses on key parameters within the MSC culture environment that affect the nature and functionality of the secretome. This information is pertinent to the development of bioprocesses aimed at scaling up the production of secretome-derived products for their use as therapeutics. PMID- 30275843 TI - Asthma. AB - Asthma is the most common respiratory disorder in Canada. Despite significant improvement in the diagnosis and management of this disorder, the majority of Canadians with asthma remain poorly controlled. In most patients, however, control can be achieved through the use of avoidance measures and appropriate pharmacological interventions. Inhaled corticosteroids (ICS) represent the standard of care for the majority of patients. Combination ICS/long-acting beta2 agonist inhalers are preferred for most adults who fail to achieve control with ICS therapy. Biologic therapies targeting immunoglobulin E or interleukin-5 are recent additions to the asthma treatment armamentarium and may be useful in select cases of difficult to control asthma. Allergen-specific immunotherapy represents a potentially disease-modifying therapy for many patients with asthma, but should only be prescribed by physicians with appropriate training in allergy. In addition to avoidance measures and pharmacotherapy, essential components of asthma management include: regular monitoring of asthma control using objective testing measures such as spirometry, whenever feasible; creation of written asthma action plans; assessing barriers to treatment and adherence to therapy; and reviewing inhaler device technique. This article provides a review of current literature and guidelines for the appropriate diagnosis and management of asthma in adults and children. PMID- 30275844 TI - Atopic dermatitis. AB - Atopic dermatitis (AD) is a common, chronic skin disorder that can significantly impact the quality of life of affected individuals as well as their families. Although the pathogenesis of the disorder is not completely understood, it appears to result from the complex interplay between defects in skin barrier function, environmental and infectious agents, and immune dysregulation. There are no diagnostic tests for AD; therefore, the diagnosis is based on specific clinical criteria that take into account the patient's history and clinical manifestations. Successful management of the disorder requires a multifaceted approach that involves education, optimal skin care practices, anti-inflammatory treatment with topical corticosteroids and/or topical calcineurin inhibitors, the management of pruritus, and the treatment of skin infections. Systemic immunosuppressive agents may also be used, but are generally reserved for severe flare-ups or more difficult-to-control disease. Topical corticosteroids are the first-line pharmacologic treatments for AD, and evidence suggests that these agents may also be beneficial for the prophylaxis of disease flare-ups. Although the prognosis for patients with AD is generally favourable, those patients with severe, widespread disease and concomitant atopic conditions, such as asthma and allergic rhinitis, are likely to experience poorer outcomes. PMID- 30275845 TI - Allergen-specific immunotherapy. AB - Allergen-specific immunotherapy is a potentially disease-modifying therapy that is effective for the treatment of allergic rhinitis/conjunctivitis, allergic asthma and stinging insect hypersensitivity. However, despite its proven efficacy in these conditions, it is frequently underutilized in Canada. The decision to proceed with allergen-specific immunotherapy should be made on a case-by-case basis, taking into account individual patient factors, such as the degree to which symptoms can be reduced by avoidance measures and pharmacological therapy, the amount and type of medication required to control symptoms, the adverse effects of pharmacological treatment, and patient preferences. Since this form of therapy carries a risk of anaphylactic reactions, it should only be prescribed by physicians who are adequately trained in the treatment of allergic conditions. Furthermore, for subcutaneous therapy, injections must be given under medical supervision in clinics that are equipped to manage anaphylaxis. In this article, the authors review the indications and contraindications, patient selection criteria, and details regarding the administration, safety and efficacy of allergen-specific immunotherapy. PMID- 30275846 TI - Non-IgE-mediated food hypersensitivity. AB - Non-immunoglobulin E (IgE)-mediated food hypersensitivity includes a spectrum of disorders that predominantly affect the gastrointestinal tract. This review will focus on the following more common non-IgE-mediated food hypersensitivity syndromes: food protein-induced enterocolitis syndrome (FPIES), allergic proctocolitis (AP), food protein-induced enteropathy (FPE) and celiac disease. FPIES, AP and FPE typically present in infancy and are most commonly triggered by cow's milk protein or soy. The usual presenting features are profuse emesis and dehydration in FPIES; blood-streaked and mucousy stools in AP; and protracted diarrhea with malabsorption in FPE. Since there are no confirmatory noninvasive diagnostic tests for most of these disorders, the diagnosis is based on a convincing history and resolution of symptoms with food avoidance. The mainstay of management for FPIES, AP and FPE is avoidance of the suspected inciting food, with periodic oral food challenges to assess for resolution, which generally occurs in the first few years of life. Celiac disease is an immune-mediated injury caused by the ingestion of gluten that leads to villous atrophy in the small intestine in genetically susceptible individuals. Serologic tests and small intestinal biopsy are required to confirm the diagnosis of celiac disease, and management requires life-long adherence to a strict gluten-free diet. PMID- 30275847 TI - Early introduction of foods to prevent food allergy. AB - Food allergy is a growing public health problem, and in many affected individuals, the food allergy begins early in life and persists as a lifelong condition (e.g., peanut allergy). Although early clinical practice guidelines recommended delaying the introduction of peanut and other allergenic foods in children, this may have in fact contributed to the dramatic increase in the prevalence of food allergy in recent decades. In January 2017, new guidelines on peanut allergy prevention were released which represented a significant paradigm shift in early food introduction. Development of these guidelines was prompted by findings from the Learning Early About Peanut Allergy study-the first randomized trial to investigate early allergen introduction as a strategy to prevent peanut allergy. This article will review and compare the new guidelines with previous guidelines on food introduction, and will also review recent evidence that has led to the paradigm shift in early food introduction. PMID- 30275848 TI - Eosinophilic esophagitis. AB - Eosinophilic esophagitis (EoE) is an atopic condition of the esophagus that has become increasingly recognized over the last 15 years. Diagnosis of the disorder is dependent on the patient's clinical manifestations, and must be confirmed by histologic findings on esophageal mucosal biopsies. Patients with EoE should be referred to an allergist for optimal management, which may include dietary modifications and pharmacologic agents such as corticosteroids, and for the diagnosis and management of comorbid atopic conditions. Mechanical dilation of the esophagus may also be necessary. The epidemiology, pathophysiology, diagnosis, treatment, and prognosis of EoE are discussed in this review. PMID- 30275849 TI - Drug allergy. AB - Drug allergy encompasses a spectrum of immunologically-mediated hypersensitivity reactions with varying mechanisms and clinical presentations. This type of adverse drug reaction not only affects patient quality of life, but may also lead to delayed treatment, unnecessary investigations, and even mortality. Given the myriad of symptoms associated with the condition, diagnosis is often challenging. Therefore, referral to an allergist experienced in the identification, diagnosis and management of drug allergy is recommended if a drug-induced allergic reaction is suspected. Diagnosis relies on a careful history and physical examination and, in some instances, skin testing and graded challenges. Induction of drug tolerance procedures may also be required. The most effective strategy for the management of drug allergy is avoidance or discontinuation of the offending drug. When available, alternative medications with unrelated chemical structures should be substituted. Cross-reactivity among drugs should be taken into consideration when choosing alternative agents. Additional therapy for drug hypersensitivity reactions is largely supportive and may include topical corticosteroids, oral antihistamines and, in severe cases, systemic corticosteroids. In the event of anaphylaxis, the treatment of choice is injectable epinephrine. If a particular drug to which the patient is allergic is indicated and there is no suitable alternative, induction of drug tolerance procedures may be considered to induce temporary tolerance to the drug. This article provides a background on drug allergy and strategies for the diagnosis and management of some of the most common drug-induced allergic reactions, such as penicillin, sulfonamides, cephalosporins, radiocontrast media, local anesthetics, general anesthetics, acetylsalicylic acid and non-steroidal anti-inflammatory drugs, and therapeutic monoclonal antibodies. PMID- 30275850 TI - Primary immunodeficiency. AB - Primary immunodeficiency disorder (PID) refers to a large heterogeneous group of disorders that result from defects in immune system development and/or function. PIDs are broadly classified as disorders of adaptive immunity (i.e., T cell, B cell or combined immunodeficiencies) or of innate immunity (e.g., phagocyte and complement disorders). Although the clinical manifestations of PIDs are highly variable, many disorders involve an increased susceptibility to infection. Early consultation with a clinical immunologist is essential, as timely diagnosis and treatment are imperative for preventing significant disease-associated morbidity. PIDs should be suspected in patients with: recurrent sinus or ear infections or pneumonias within a 1 year period; failure to thrive; poor response to prolonged use of antibiotics; persistent thrush or skin abscesses; or a family history of PID. Patients with multiple autoimmune diseases should also be evaluated. Diagnostic testing often involves lymphocyte proliferation assays, flow cytometry, measurement of serum immunoglobulin (Ig) levels, assessment of serum specific antibody titers in response to vaccine antigens, neutrophil function assays, stimulation assays for cytokine responses, and complement studies. The treatment of PIDs is complex and generally requires both supportive and definitive strategies. Ig replacement therapy is the mainstay of therapy for B cell disorders, and is also an important supportive treatment for many patients with combined immunodeficiency disorders. The disorders affecting the activity of the T-cell arm of the adaptive system, such as severe combined immunodeficiency, require immune reconstitution as soon as possible. The treatment of innate immunodeficiency disorders varies depending on the type of defect, but may involve antifungal and antibiotic prophylaxis, cytokine replacement, vaccinations and bone marrow transplantation. This article provides an overview of the major categories of PIDs and strategies for the appropriate diagnosis and management of these rare disorders. PMID- 30275852 TI - Patterns of Practice in Radiotherapy for Breast Cancer in Korea. AB - Adjuvant radiotherapy (RT) is a well-established treatment for breast cancer. However, there is a large degree of variation and controversy in practice patterns. A nationwide survey on the patterns of practice in breast RT was designed by the Division for Breast Cancer of the Korean Radiation Oncology Group. All board-certified members of the Korean Society for Radiation Oncology were sent a questionnaire comprising 39 questions on six domains: hypofractionated whole breast RT, accelerated partial breast RT, postmastectomy RT (PMRT), regional nodal RT, RT for ductal carcinoma in situ, and RT toxicity. Sixty-four radiation oncologists from 54 of 86 (62.8%) hospitals responded. Twenty-three respondents (35.9%) used hypofractionated whole breast RT, and the most common schedule was 43.2 Gy in 16 fractions. Only three (4.7%) used accelerated partial breast RT. Five (7.8%) used hypofractionated PMRT, and 40 (62.5%) had never used boost RT after chest wall irradiation. Indications for regional nodal RT varied; >=pN2 (n=7) versus >=pN1 (n=17) versus >=pN1 with pathologic risk factors (n=40). Selection criteria for internal mammary lymph node (IMN) irradiation also varied; only four (6.3%) always treated IMN when regional nodal RT was administered and 30 (46.9%) treated IMN only if IMN involvement was identified through imaging. Thirty-one (48.4%) considered omission of whole breast RT after breast-conserving surgery for ductal carcinoma in situ based on clinical and pathologic risk factors. Fifty-two (81.3%) used heart-sparing techniques. Overall, there were wide variations in the patterns of practice in breast RT in Korea. Standard guidelines are needed, especially for regional nodal RT and omission of RT for ductal carcinoma in situ. PMID- 30275853 TI - Hsa-miRNA-143-3p Reverses Multidrug Resistance of Triple-Negative Breast Cancer by Inhibiting the Expression of Its Target Protein Cytokine-Induced Apoptosis Inhibitor 1 In Vivo. AB - Purpose: Multidrug resistance (MDR) remains a major obstacle in the treatment of triple-negative breast cancer (TNBC) with conventional chemotherapeutic agents. A previous study demonstrated that hsa-miRNA-143-3p plays a vital role in drug resistance of TNBC. Downregulation of hsa-miRNA-143-3p upregulated the expression of its target protein cytokine-induced apoptosis inhibitor 1 (CIAPIN1) in order to activate MDR, while upregulation of hsa-miRNA-143-3p effectively enhances the sensitivity of drug-resistant TNBC cells to chemotherapeutics. The present study aimed to further verify these findings in vivo. Methods: We established a hypodermic tumor nude mice model using paclitaxel-resistant TNBC cells. We expressed ectopic hsa-miRNA-143-3p under the control of a breast cancer-specific human mammaglobin promoter that guided the efficient expression of exogenous hsa miRNA-143-3p only in breast cancer cells. Thereafter, we overexpressed hsa-miRNA 143-3p in xenografts using a recombinant virus system and quantified the expression of hsa-miRNA-143-3p, CIAPIN1 protein, and proteins encoded by related functional genes by western blot. Results: We successfully completed the prospective exploration of the intravenous virus injection pattern from extensive expression to targeted expression. The overexpression of hsa-miRNA-143-3p significantly alleviated chemoresistance of TNBC by inhibiting viability. In addition, we observed that the expression of CIAPIN1 as a hsa-miRNA-143-3p target protein was remarkably decreased. Conclusion: We partly illustrated the mechanism underlying the hsa-miRNA-143-3p/CIAPIN1 drug resistance pathway. HsamiRNA-143-3p as a tumor suppressive microRNA may be a novel target to effectively reverse MDR of TNBC in vivo. PMID- 30275851 TI - The Epigenetics of Triple-Negative and Basal-Like Breast Cancer: Current Knowledge. AB - Breast cancer has the highest incidence among all malignancies diagnosed in women. Therapies have significantly improved over the years due to extensive molecular and clinical research; in a large number of cases, targeted therapies have provided better prognosis. However, one specific subtype remains elusive to targeted therapies-the triple-negative breast cancer. This immunohistochemically defined subtype is resistant to both endocrine and targeted therapies, leading to its poor prognosis. A field that is of great promise in current cancer research is epigenetics. By studying the epigenetic mechanisms underlying tumorigenesis DNA methylation, histone modifications, and noncoding RNAs-advances in cancer treatment, diagnosis, and prevention are possible. This review aims to synthesize the epigenetic discoveries that have been made related to the triple-negative breast cancer. PMID- 30275854 TI - Hypoxia-Inducible Factor 1alpha Regulates the Transforming Growth Factor beta1/SMAD Family Member 3 Pathway to Promote Breast Cancer Progression. AB - Purpose: The transforming growth factor beta1 (TGF-beta1)/SMAD family member 3 (SMAD3) pathway, and hypoxia-inducible factor 1alpha (HIF-1alpha) are two key players in various types of malignancies including breast cancer. The TGF beta1/SMAD3 pathway can interact with HIF-1alpha in some diseases; however, their interaction in breast cancer is still unknown. Therefore, our study aimed to investigate the interactions between the TGF-beta1/SMAD3 pathway and HIF-1alpha in breast cancer. Methods: Expression of HIF-1alpha in serum of breast cancer patients and healthy controls was detected by quantitative reverse transcription polymerase chain reaction, and the diagnostic value of HIF-1alpha for breast cancer was evaluated by receiver operating characteristic curve analysis. Breast cancer cell lines overexpressing SMAD3 and HIF-1alpha were established. Cell apoptosis and proliferation following different treatments were detected by 3 (4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, and cell counting kit 8, respectively. Expression of related proteins was detected by western blot. Results: Serum levels of HIF-1alpha were higher in breast cancer patients than in normal controls. Both SMAD3 and HIF-1alpha overexpression inhibited cell apoptosis and promoted cell proliferation. Treatment with inhibitors of HIF 1alpha and SMAD3 promoted apoptosis in breast cancer cells and inhibited their proliferation. Overexpression of HIF-1alpha promoted the expression of TGF-beta1 and SMAD3, while SMAD3 overexpression did not significantly affect expression of HIF-1alpha or TGF-beta1. Conclusion: HIF-1alpha serves as an upstream regulator of the TGF-beta1/SMAD3 pathway and promotes the growth of breast cancer. PMID- 30275855 TI - Deficiency of Follistatin-Like Protein 1 Accelerates the Growth of Breast Cancer Cells at Lung Metastatic Sites. AB - Purpose: Follistatin-like protein 1 (FSTL1) is a secreted glycoprotein that has been shown to play a role in various types of cancer. However, the clinical significance and function of FSTL1 in breast cancer have not been reported. We investigated the role of FSTL1 in breast cancer in this study. Methods: Enzyme linked immunosorbent assays, western blot analysis, and reverse transcription polymerase chain reaction were used to monitor the expression of FSTL1 in breast cancer tissue and in serum samples from breast cancer patients. We employed a 4T1 breast cancer model and Fstl1 +/- mice for in vivo studies. Hematoxylin and eosin staining, western blot analysis, and RNA sequencing were used to analyze the effect of FSTL1 on primary tumor growth and lung metastasis. Results: We demonstrated that the expression of FSTL1 is reduced in both the breast cancer tissue and the serum of breast cancer patients. We showed that reduced levels of FSTL1 in serum correlate with elevated expression of Ki-67 and epidermal growth factor receptor (EGFR) in cancer tissues. Moreover, lowered expression of FSTL1 was associated with decreased survival in breast cancer patients. Experiments on the Fstl1 +/- mouse model established that FSTL1 deficiency had no effect on primary tumor growth, but increased the lung metastases of breast cancer cells, resulting in reduced survival of tumor-bearing mice. RNA sequencing found significantly reduced expression of Egln3 and increased expression of EGFR in Fstl1 +/- mice. Thus, our results suggest that FSTL1 may affect the expression of EGFR through Egln3, inhibiting the proliferation of breast cancer cells at lung metastatic sites. Conclusion: In conclusion, we suggest a suppressor role of FSTL1 in breast cancer lung metastasis. Furthermore, FSTL1 may represent a potential prognostic biomarker and a candidate therapeutic target in breast cancer patients. PMID- 30275856 TI - Long Noncoding RNA Signature and Disease Outcome in Estrogen Receptor-Positive Breast Cancer Patients Treated with Tamoxifen. AB - Purpose: Recent data have shown that the expression levels of long noncoding RNAs (lncRNAs) are associated with tamoxifen sensitivity in estrogen receptor (ER) positive breast cancer. Herein, we constructed an lncRNA-based model to predict disease outcomes of ER-positive breast cancer patients treated with tamoxifen. Methods: LncRNA expression information was acquired from Gene Expression Omnibus by re-mapping pre-existing microarrays of patients with ER-positive breast cancer treated with tamoxifen. The distant metastasis-free survival (DMFS) predictive signature was subsequently built based on a Cox proportional hazard regression model in discover cohort patients, which was further evaluated in another independent validation dataset. Results: Six lncRNAs were found to be associated with DMFS in the discover cohort, which were used to construct a tamoxifen efficacy-related lncRNA signature (TLS). There were 133 and 362 patients with TLS high- and low-risk signatures in the discover cohort. Both univariate and multivariate analysis demonstrated that TLS was associated with DMFS. TLS high risk patients had worse outcomes than low-risk patients, with a hazard ratio of 4.04 (95% confidence interval, 2.83-5.77; p<0.001). Both subgroup analysis and receiver operating characteristic analysis indicated that TLS performed better in lymph node-negative, luminal B, 21-gene recurrence score high-risk, and 70-gene prognosis signature high-risk patients. Moreover, in a comparison of the 21-gene recurrence score and 70-gene prognosis signature, TLS showed a similar area under receiver operating characteristic curve in all patients. Gene Set Enrichment Analysis indicated that TLS high-risk patients showed different gene expression patterns related to the cell cycle and nucleotide metabolism from those of low risk patients. Conclusion: This six-lncRNA signature was associated with disease outcome in ER-positive breast cancer patients treated with tamoxifen, which is comparable to previous messenger RNA signatures and requires further clinical evaluation. PMID- 30275857 TI - High RNA-binding Motif Protein 3 Expression Is Associated with Improved Clinical Outcomes in Invasive Breast Cancer. AB - Purpose: Expression of RNA-binding motif protein 3 (RBM3) is induced by hypoxia and hypothermia. Recently, high expression of RBM3 was reported to be associated with a good prognosis in colon cancer, prostate cancer, ovarian cancer, and malignant melanoma. Studies on RBM3 in invasive breast carcinoma (IBC), however, are limited. Methods: RBM3 expression was examined using a tissue microarray from 361 patients with IBC. Immunohistochemistry was performed for estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), and Ki-67 to compare the expression of these markers. For scoring of RBM3 expression, NF (nuclear staining fraction)*NI (nuclear staining intensity) was used. The RBM3 expression score was considered indicative of either low (<=4) or high (>4) expression. Western blot analysis was performed on breast cancer cell lines to evaluate RBM3 expression. Results: Of the total 361 samples, 240 (66.5%) exhibited high RBM3 expression. High RBM3 expression was significantly associated with positivity for ER (p<0.001), PR (p<0.001), T stage (p<0.001), histologic grade (p<0.001), and % Ki-67 staining (p=0.004). Multivariate analysis revealed that high RBM3 expression was closely associated with prolonged disease-free survival (DFS) (p<0.001) and overall survival (OS) (p<0.001). Western blot analysis revealed reduced RBM3 expression in HCC1954 (HER2-enriched) and BT-20 (basal-like) cells with an aggressive phenotype. Conclusion: High nuclear RBM3 expression is strongly associated with a prolonged DFS and OS. Furthermore, RBM3 expression is closely associated with good prognostic markers such as ER and PR in IBC. High nuclear RBM3 expression is, therefore, a critical biomarker of favorable clinical outcomes in IBC. PMID- 30275858 TI - Expression of DNA Damage Response Proteins and Associations with Clinicopathologic Characteristics in Chinese Familial Breast Cancer Patients with BRCA1/2 Mutations. AB - Purpose: The characteristic expression of DNA damage response proteins in familial breast cancers with BRCA1, BRCA2, or non-BRCA1/2 mutations has not been analyzed in Chinese patients. Our study aimed to assess the differential expression of microcephalin 1 (BRIT1), ATM serine/threonine kinase (ATM), checkpoint kinase 2 (CHEK2), BRCA1, RAD51 recombinase (RAD51), and poly (ADP ribose) polymerase 1 (PARP-1) and establish the profile of Chinese familial breast cancers with different mutation status. Methods: We constructed five tissue microarrays from 183 familial breast cancer patients (31 with BRCA1 mutations; 14 with BRCA2 mutations, and 138 with non-BRCA1/2 mutations). The DNA response and repair markers used for immunohistochemistry analysis included BRIT1, ATM, CHEK2, BRCA1, RAD51, and PARP-1. The expressions of these proteins were analyzed in BRCA1/2 mutated tumors. The association between pathologic characteristics with BRCA1/2 mutation status was also analyzed. Results: In familial breast cancer patients, BRCA1 mutated tumors were more frequent with high nuclear grade, estrogen receptor/progesterone receptor/human epidermal growth factor receptor 2 negative, low Ki-67, and positive CK5/6. BRCA1 mutated tumors had lower CHEK2 and higher cytoplasmic BRIT1 expression than BRCA2 and non BRCA1/2 mutation tumors. BRCA2-associated tumors showed higher CHEK2 and cytoplasmic RAD51 expression than those in other groups. Nuclear PARP-1 expression in BRCA1/2-associated tumors was significantly higher than in non BRCA1/2 mutation tumors. Moreover, we found quite a few of negative PARP-1 expression cases in BRCA1/2 mutated groups. Conclusion: The clinicopathologic findings of BRCA1-associated Chinese familial breast cancers were similar to the results of other studies. Chinese familial breast cancer patients with BRCA1/2 mutations might have distinctive expression of different DNA damage response proteins. The reduced expression of PARP-1 in Chinese BRCA1/2 mutated breast cancer patients could influence the therapeutic outcome of PARP-1 inhibitors. PMID- 30275859 TI - Comparative Study between Sentinel Lymph Node Biopsy and Axillary Dissection in Patients with One or Two Lymph Node Metastases. AB - Purpose: Sentinel lymph node biopsy (SLNB) is a standard axillary surgery in early breast cancer. If the SLNB result is positive, subsequent axillary lymph node dissection (ALND) is a routine procedure. In 2011, the American College of Surgeons Oncology Group Z0011 trial revealed that ALND may not be necessary in early breast cancer with one or two positive sentinel lymph nodes. The purpose of this study was to compare outcomes among Korean patients with one or two positive axillary lymph nodes in the final pathology who did and did not undergo ALND. Methods: A total of 131,717 patients from the Korea Breast Cancer Society registry database received breast cancer surgery from January 1995 to December 2014. Inclusion criteria were T stage 1 or 2, one or two positive lymph nodes, and having received breast-conserving surgery (BCS), whole breast radiation therapy, and no neoadjuvant therapy. We analyzed the differences in disease specific survival (DSS) and overall survival (OS) between patients who received SLNB only and those who underwent SLNB+ALND. Results: A total 4,442 patients met the inclusion criteria, with 1,268 (28.6%) in the SLNB group and 3,174 (71.4%) in the SLNB+ALND group. There were no differences in DSS and OS between the two groups (p=0.378 and p=0.925, respectively). The number of patients who underwent SLNB alone for one or two positive lymph nodes increased continuously from 2004 to 2014. Conclusion: Korean patients with early breast cancer and 1 or 2 positive axillary lymph nodes who received BCS plus SLNB showed no significant difference in DSS and OS regardless of whether they received ALND. The findings of this retrospective study demonstrate that omitting ALND can be considered when treating selected patients with early breast cancer who have one or two positive lymph nodes. PMID- 30275860 TI - Evaluating the Prediction of Breast Cancer Survival Using Lymph Node Ratio. AB - Purpose: Previous oncological studies showed that lymph node ratio (LNR) (ratio of number of lymph nodes that tested positive for metastasis to the total number of lymph nodes examined) is a negative indicator of cancer survival. The American Joint Committee on Cancer (AJCC) staging system incorporates tumor size, lymph node involvement, and metastasis in a comprehensive model of cancer progression, but LNR alone has been shown to outperform the AJCC system in prognostic and survival predictions for various types of cancer. The effectiveness of LNR has not been evaluated in breast cancer staging. Evaluating LNR for predicting cancer staging in breast cancer has the potential to improve treatment recommendations. Methods: The Surveillance, Epidemiology, and End Results dataset was used to identify 10,655 breast cancer patients who underwent nodal evaluation from 2010 to 2013, and their LNRs were calculated. Descriptive statistics of lymph node evaluation in the patients are provided. Logistic regression with LNR as the continuous independent variable was conducted to determine whether LNR could predict cancer progression, coded as regional or distant. Analysis was conducted using SPSS version 24. Results: Patient's mean age was 59.43+/-18.62. Logistic regression analysis revealed that for every 1.3% increase in LNR, the odds of falling into the distant stage of the TNM staging system increased by 13.7% (odds ratio, 14.73; 95% confidence interval, 12.00-18.08). Conclusion: LNR, while correlated with breast cancer staging, serves as a better predictor of survival. Precision staging can influence treatment modality, and improved treatments can significantly improve quality of life. Additional research and diagnostic examinations using LNR as a potential tool for accurate staging in breast cancer patients are warranted. PMID- 30275861 TI - Comparison of Oncoplastic Breast-Conserving Surgery and Breast-Conserving Surgery Alone: A Meta-Analysis. AB - Purpose: The use of oncoplastic reconstruction for breast-conserving surgery (BCS) extends benefits beyond merely minimizing poor cosmetic results. However, the feasibility and oncological safety of oncoplastic surgery (OPS) are controversial. Methods: This meta-analysis aimed to compare the short-term and long-term oncological outcomes of BCS alone and BCS plus OPS. Relevant studies published before July 2017 in the Embase, the Cochrane Library, PubMed, and Web of Science databases were screened and collected. The meta-analysis was performed using STATA software (Stata Corp.). Results: A total of 3,789 patients from 11 studies were included, with 2,691 patients in the BCS-alone group and 1,098 patients in the BCS plus OPS group. The demographics were similar between both groups, and no significant difference was observed in pathological T and N stages between the two groups. Re-excision was less common (relative risk [RR], 0.66; p=0.009) and the positive-margin rate was lower, but not significantly (RR, 0.83; p=0.191), in the BCS plus OPS group than in the BCS-alone group. The local and distal recurrence rates were similar in both groups. Both disease-free survival (hazard ratio [HR], 1.19; 95% confidence interval [CI], 0.96-1.49; p=0.112) and overall survival (HR, 1.14; 95% CI, 0.76-1.69; p=0.527) did not differ between the two groups. Conclusion: A combination of BCS and OPS is preferred over BCS alone for decreasing re-excisions and provides similar long-term survival as BCS alone in patients with breast cancer. PMID- 30275863 TI - Gasless Robot-Assisted Nipple-Sparing Mastectomy: A Case Report. AB - Robotic surgical systems enhance surgical accuracy and efficiency by applying advanced technologies such as artificial arm joints to provide higher degrees of freedom of movement and high-quality three-dimensional images. However, the application of robotic surgical systems to breast surgery has not been widely attempted. The robotic system would improve cosmesis by enabling surgery using a single small incision. We report the first case of a gasless robot-assisted nipple-sparing mastectomy and immediate reconstruction in a patient with early breast cancer. PMID- 30275862 TI - The Novel Pathogenic Mutation c.849dupT in BRCA2 Contributes to the Nonsense Mediated mRNA Decay of BRCA2 in Familial Breast Cancer. AB - In this study, we used next-generation sequencing methods to screen 300 individuals for BRCA1 and BRCA2. A novel mutation (c.849dupT) in BRCA2 was identified in a female patient and her unaffected brothers. This mutation leads to the truncation of BRCA2 functional domains. Moreover, BRCA2 mRNA expression levels in mutation carriers are significantly reduced compared to noncarriers. Immunofluorescence and western blot assays showed that this mutation resulted in reduced BRCA2 protein expression. Thus, we identified a novel mutation that damaged the function and expression of BRCA2 in a family with breast cancer history. The pedigree analysis suggested that this mutation is strongly associated with familial breast cancer. Genetic counsellors suggest that mutation carriers in this family undergo routine screening for breast cancer, as well as other malignancies, such as prostate and ovarian cancer. The effects of this BRCA2 mutation on drug resistance should be taken into consideration during treatment. PMID- 30275864 TI - Extraocular Muscles Involvement as the Initial Presentation in Metastatic Breast Cancer. AB - Orbital metastasis is a rare event, and metastatic disease affecting the extraocular muscles is an even less frequent complication of solid tumors. Herein, we report an unusual case of ptosis as the initial presentation of an invasive breast cancer. A 68-year-old woman presented with III and VI partial nerve paresis, secondary to a compressive retrobulbar mass. Magnetic resonance imaging revealed an infiltrative lesion involving the extraocular muscles. Tissue biopsy yielded a result compatible with metastasis to the orbit, with immunohistochemistry analysis suggesting breast as the primary organ. Mammography identified an area of architectural distortion; stereotactic wire-guided biopsy confirmed the result of the previous orbital biopsy. A positron emission tomography scan demonstrated disseminated disease. Palliative chemotherapy with bone-modulating agents and subsequent hormonal therapy was proposed. Unfortunately, the patient did not respond to therapy and died 38 months after diagnosis. PMID- 30275865 TI - Moxibustion-Simulating Bipolar Radiofrequency Suppresses Weight Gain and Induces Adipose Tissue Browning via Activation of UCP1 and FGF21 in a Mouse Model of Diet Induced Obesity. AB - Background: Obesity is a pathological condition associated with various diseases including diabetes, stroke, arthritis, infertility, and heart disease. Moxibustion is widely used to prevent and manage obesity in traditional Asian medicine. We tested our hypothesis that moxibustion-simulating bipolar radiofrequency (M-RF) can suppress total body and white adipose tissue (WAT) weight gain via induction of WAT browning in a mouse model of diet-induced obesity (DIO). Methods: We designed an M-RF device that could accurately adjust the depth and temperature at which heat stimulation was administered into the abdomen of DIO mice. High-fat-fed male C57BL/6 mice were treated with the M-RF device every two or three days for three weeks. We then harvested WAT and serum from the mice and measured total body and WAT weight, size of adipocytes, mitochondrial contents, features of the dead adipocyte environment, and levels of uncoupling protein 1 (UCP1) and fibroblast growth factor 21 (FGF21). Results: Heat stimulation by M-RF in DIO mice resulted in precise temperature adjustment in the mice abdomen, with variance less than 1 degrees C. Additionally, M-RF stimulation inhibited body and WAT weight gain, resulting in increased formation of beige adipocytes, increased mitochondrial content, and decreased formation of dead adipocytes in WAT. Moreover, treatment of M-RF induced expression of UCP1 and FGF21 in serum and/or epididymal WATs in DIO mice. Conclusion: Heat stimulation by M-RF treatment induced upregulation of UCP1 and FGF21 expression in serum and/or WATs, which was correlated with reduced total body and WAT weight gain in DIO mice. PMID- 30275866 TI - Guzhi Zengsheng Zhitongwan, a Traditional Chinese Medicinal Formulation, Stimulates Chondrocyte Proliferation through Control of Multiple Genes Involved in Chondrocyte Proliferation and Differentiation. AB - Chinese materia medica (CMM) are essential components of traditional Chinese medicine, and Chinese medicinal formulas consisting of 2 or more types of CMM are widely used. These formulations have played a pivotal role in health protection and disease control for thousands of years. Guzhi Zengsheng Zhitongwan (GZZSZTW), which represents one of the Chinese medicinal formulations, has been used for several decades to treat joint diseases. However, the exact molecular mechanism underlying its efficacy in treating osteoarthritis remains to be elucidated. In the present study, we investigated the effects of GZZSZTW on primary chondrocytes. We demonstrated that GZZSZTW significantly promoted chondrocyte viability, maintained chondrocytes in a continuous proliferative state, and prevented their further differentiation. These effects were achieved by the synergistic interactions of various herbs and their active components in GZZSZTW through an increase in the expression levels of functional genes participating in chondrocyte commitment and proliferation and a decrease in the expression levels of genes involved in chondrocyte differentiation. GZZSZTW treatment also decreased the expression levels of genes that inhibited chondrocyte proliferation. Thus, this study has greatly deepened the current knowledge about the molecular effects of GZZSZTW on chondrocytes. It has also shed new light on possible strategies to further prevent and treat cartilage-related diseases by using traditional Chinese medicinal formulations. PMID- 30275867 TI - Development, Characterization, and Evaluation of Novel Broad-Spectrum Antimicrobial Topical Formulations from Cymbopogon martini (Roxb.) W. Watson Essential Oil. AB - Background: Skin infections were the most frequently encountered of all infections and the 4th leading cause of nonfatal disease burden. Topical drugs have been used for the management of skin infections. The growing concern of drug resistance to the topical agents has warned the need for continuous development of novel drug. Essential oils are the best candidate for new drug with different mode of action and target as they are rich in chemical constituents. Objective: To evaluate and develop safe and effective topical antimicrobial formulations from essential oil of Cymbopogon martini. Method. Essential oil was extracted using hydrodistillation aerial part C. martini and topical formulations were prepared in five different semisolid bases. In vitro antimicrobial investigations were performed on essential oil and topical formulations. Skin sensitizations of the formulations were evaluated using guinea pig maximization. Results: The essential oil of C. martini has shown broad-spectrum antimicrobial potency against all tested organisms with MIC value ranging from 0.65 to 10 MUg/ml. Absolute inhibitions of growth of fungi were observed against Trichophyton mentagrophytes and Trichophyton rubrum at concentrations above 1% of oil and against Microsporum canis and Trichophyton verrucosum at a concentration of 4% oil. Among topical formulations, the highest antimicrobial activity was recorded in hydrophilic ointment followed by macrogol blend ointment. The antimicrobial activity of oil was higher in fungal pathogen compared to bacteria. Gram positive bacteria were more sensitive than gram negative bacteria. Hydrophilic and macrogol blend ointment containing 5% oil did not produce any skin sensitization on guinea pigs. Conclusion: In conclusion, topical formulations of C. martini essential oil can be alternative topical agents with safe broad-spectrum activity for the treatment of skin disorder. Further studies should focus on shelf life study and clinical study of the product. PMID- 30275868 TI - Convergent evolution of the ladder-like ventral nerve cord in Annelida. AB - Background: A median, segmented, annelid nerve cord has repeatedly been compared to the arthropod and vertebrate nerve cords and became the most used textbook representation of the annelid nervous system. Recent phylogenomic analyses, however, challenge the hypothesis that a subepidermal rope-ladder-like ventral nerve cord (VNC) composed of a paired serial chain of ganglia and somata-free connectives represents either a plesiomorphic or a typical condition in annelids. Results: Using a comparative approach by combining phylogenomic analyses with morphological methods (immunohistochemistry and CLSM, histology and TEM), we compiled a comprehensive dataset to reconstruct the evolution of the annelid VNC. Our phylogenomic analyses generally support previous topologies. However, the so far hard-to-place Apistobranchidae and Psammodrilidae are now incorporated among the basally branching annelids with high support. Based on this topology we reconstruct an intraepidermal VNC as the ancestral state in Annelida. Thus, a subepidermal ladder-like nerve cord clearly represents a derived condition. Conclusions: Based on the presented data, a ladder-like appearance of the ventral nerve cord evolved repeatedly, and independently of the transition from an intraepidermal to a subepidermal cord during annelid evolution. Our investigations thereby propose an alternative set of neuroanatomical characteristics for the last common ancestor of Annelida or perhaps even Spiralia. PMID- 30275869 TI - The modular organization of roe deer (Capreolus capreolus) body during ontogeny: the effects of sex and habitat. AB - Background: As a small artiodactyl, the roe deer (Capreolus capreolus L.) is characterized by biological plasticity and great adaptability demonstrated by their survival under a wide variety of environmental conditions. In order to depict patterns of phenotypic variation of roe deer body this study aims to quantify variation during ontogenetic development and determine how sex-specific reproductive investment and non-uniform habitat differences relate to phenotypic variation and do these differential investments mold the patterns of phenotypic variation through modular organisation. Results: Patterns of phenotypic correlation among body traits change during the ontogeny of roe deer, with differential influence of sex and habitat type. Modularity was found to be a feature of closed habitats with trunk+forelimbs+hindlimbs as the best supported integration/modularity hypothesis for both sexes. The indices of integration and evolvability vary with habitat type, age and sex where increased integration is followed by decreased evolvability. Conclusion: This is the first study that quantifies patterns of correlation in the roe deer body and finds pronounced changes in correlation structure during ontogeny affected by sex and habitat type. The correlation structure of the roe deer body is developmentally written over the course of ontogeny but we do not exclude the influence of function on ontogenetic changes. Modularity arises with the onset of reproduction (subadults not being modular) and is differentially expressed in males and females from different habitats. Both adult males and females show modularity in primordial, closed habitats. Overall, all these findings are important as they provide support to the idea that modularity can evolve at the population level and change fast within a species. PMID- 30275870 TI - Dietary n-3 long-chain polyunsaturated fatty acids upregulate energy dissipating metabolic pathways conveying anti-obesogenic effects in mice. AB - Background: We previously reported on the anti-obesogenic and anti-inflammatory effects associated with n-3 long-chain polyunsaturated fatty acids (LCPUFA) in our diet-induced obesity (DIO) mouse model. Two isocaloric high-fat diets (HFDs; 48 kJ% fat), HFD (HF) and n-3 LCPUFA-enriched HFD (HF/n-3), and a control diet (C; 13 kJ% fat) were used. The underlying mechanisms however have largely remained unclear. Here, we assessed whether the reduced fat mass reflected n-3 LCPUFA-induced expression changes in lipid metabolism of the intestine, liver, and interscapular brown adipose tissue (iBAT), as well as increased iBAT thermogenic capacity. Methods: For HF/n-3, saturated and monounsaturated fatty acids were partially substituted by n-3 LCPUFA eicosapentaenoic acid and docosahexaenoic acid to achieve a balanced n-6/n-3 PUFA ratio (0.84) compared to the unbalanced ratios of HF (13.5) and C (9.85). Intestine, liver and iBAT from male C57BL/6 J mice, fed defined soybean/palm oil-based diets for 12 weeks, were further analysed. Gene and protein expression analyses, immunohistochemistry and correlation analyses for metabolic interactions were performed. Results: Compared to HF and C, our analyses suggest significantly diminished de novo lipogenesis (DNL) and/or increased hepatic and intestinal fatty acid oxidation (omega oxidation and peroxisomal beta-oxidation) in HF/n-3 mice. For iBAT, the thermogenic potential was enhanced upon HF/n-3 consistent with upregulated expression for uncoupling protein-1 and genes involved in mitochondrial biogenesis. In addition, a higher capacity for the supply and oxidation of fatty acids was observed and expression and correlation analyses indicated a coordinated regulation of energy metabolism and futile cycling of triacylglycerol (TAG). Moreover, HF/n-3 significantly increased the number of anti-inflammatory macrophages and eosinophils and significantly enhanced the levels of activated AMP-activated protein kinase alpha (AMPKalpha), peroxisome proliferator-activated receptor alpha (PPARalpha) and fibroblast growth factor 21 (FGF21). Conclusions: Our data suggest that by targeting transcriptional regulatory pathways, AMPKalpha, and FGF21 as potential mediators, HF/n-3 activated less efficient pathways for energy production, such as peroxisomal beta-oxidation, increased ATP consumption upon the induction of futile cycling of TAG, and additionally increased the thermogenic and oxidative potential of iBAT. Therefore, we consider n-3 LCPUFA as the potent inducer for upregulating energy dissipating metabolic pathways conveying anti-obesogenic effects in mice. PMID- 30275871 TI - Alpha-lipoic acid preserves skeletal muscle mass in type 2 diabetic OLETF rats. AB - Background: Increased oxidative stress and impaired antioxidant defense are important mechanisms in the pathogenesis of diabetic myopathy. Alpha-lipoic acid (ALA) has been indicated as a weight-loss treatment in rodents and humans, but studies are limited. In the present study, we aimed to determine the influence of ALA, a potent biological antioxidant, on metabolic and growth processes in diabetic rat skeletal muscle. Methods: Male 25-week-old type 2 diabetic rats (OLETF) were randomly divided into two groups, a control group (OLETF-C) and an ALA-treated group (OLETF-ALA) supplemented with 100 mg/kg ALA for 8 weeks. Age matched, healthy, nondiabetic LETO (LETO-C) rats were used as controls. Results: At 32 weeks of age, body weight was decreased by 6.8%, and the areas under the curve of IP-GTT, fasting glucose, and insulin were less in OLETF-ALA rats compared with OLETF-C rats. ALA significantly preserved muscle mass and enhanced muscle fiber cross-sectional area and fiber frequency percentage in the skeletal muscle of OLETF rats. Although the activation of myoD, myogenin, and myostatin in gastrocnemius muscle was significantly inhibited in OLETF-ALA rats relative to OLETF-C rats, there were no differences in the expression levels of muscle atrogin-1 and MuRF1 between the two groups. ALA treatment significantly increased the levels of phosphorylated 5'-AMPK, SIRT1, and PGC-1alpha, as well as the levels of phosphorylated AKT, mTOR, and p70S6 kinase in OLETF-ALA rats compared with OLETF-C rats. In contrast, the levels of phosphorylated p38 MAPK, IRS-1, and FOXO1 were decreased in OLETF-ALA rats compared with OLETF-C rats. Conclusions: ALA treatment preserved mass in the gastrocnemius muscles of OLETF rats. ALA significantly upregulated the AMPK/SIRT1/PGC-1alpha and AKT/mTOR/p70S6K signaling pathways in OLETF rat skeletal muscle. Therefore, ALA may be a potential therapeutic intervention for skeletal muscle loss in animal models of insulin resistance.

AB - Background: The use of cosmetic products in beauty salons emits numerous kinds of toxic air pollutants. The objectives of this study were to measure the concentrations of benzene, toluene, ethylbenzene, xylene, formaldehyde, and acetaldehyde in 20 large beauty salons in Tehran and relate the observed concentrations to environmental and occupational characteristics of the salons. Methods: Samples were collected from inside and outside air of 20 selected salons located in different areas of the city. Several additional parameters were recorded during the sampling process including surface area, number of active employees, type of ventilation, type of ongoing treatments, temperature, humidity. Deterministic and stochastic health risk assessment of the compounds were performed. Results: Indoor concentrations of each pollutant were significantly higher than its outdoor concentrations. Health risk assessment showed that benzene, formaldehyde and acetaldehyde represent a possible cancer risk in the beauty salons. In addition, toluene, ethylbenzene, and xylene had negligible non-carcinogenic risks. Ventilation with air purifier, and fan with open window were more effective than using just a fan. Concentrations of benzene and toluene were affected by the number of hair dying treatments. The concentration of xylene was affected by the number of hair styling. The concentration of formaldehyde was affected by the number of hair styling and number of nail treatments. Conclusion: With improved ventilation and requirements for reformulated cosmetic, concentrations of toxic air pollutants in beauty salons could be reduced.

AB - Background: Despite the substantial impact on child and maternal health, breastfeeding practices for infants remain at the suboptimum level in Bangladesh. Yet the understanding of why these practices are suboptimal, especially surrounding urban slum dwelling mothers, is unclear. The purpose of this study was to assess early infant feeding practices, examine associations with maternal factors, and uncover the facilitators and barriers to early feeding practices in selected slums of Dhaka, Bangladesh. Methods: A mixed method study was conducted from June to September 2016 using both quantitative and qualitative methods among mothers with children under the age of 6 months. The survey included 342 mother infant pairs and 18 in-depth interviews were conducted. Univariate and multiple logistic regression was used to determine status of early infant feeding practices and factors associated with exclusive breastfeeding (EBF) within the previous 24 h. Transcripts were coded to uncover the facilitators and barriers surrounding early infant feeding practices. Results: Sixty four percent (220/342) of mothers initiated breastfeeding within 1 h, 96.5% (330/342) reported feeding colostrum, and 36.3% (124/342) infants were EBF in the last 24 h. After adjusting for child gender, maternal age, education, diet and household income; infant's age (adjusted odds ratio (AOR) for 61-120 days 6.42; 95% CI 3.42, 12.1; AOR for 121-180 days 45.6; 95% CI 18.33, 113.45), prelacteal feeding (AOR 2.53; 95% CI 1.14, 4.58), lack of planning for EBF during pregnancy (AOR 4.06; 95% CI 1.09, 15.12) and infants delivered by cesarean section (AOR 2.76; 95% CI 1.34, 5.67) were negatively associated with EBF. During the 18 interviews, eight mothers reported a cesarean delivery and none of these mothers initiated breastfeeding within 1 h or exclusively breastfed. Moreover, all eight mothers gave their infants prelacteal feeds. Conclusions: The status of early infant feeding practices in Dhaka's slums was poor. The negative impact of cesarean section on all early infant feeding practices was evident in both quantitative and qualitative analysis.

AB - Background: Bayesian networks have been proposed as a way to identify possible causal relationships between measured variables based on their conditional dependencies and independencies. We explored the use of Bayesian network analyses applied to the GAW20 data to identify possible causal relationships between differential methylation of cytosine-phosphate-guanine dinucleotides (CpGs), single-nucleotide polymorphisms (SNPs), and blood lipid trait (triglycerides [TGs]). Methods: After initial exploratory linear regression analyses, 2 Bayesian networks analyses were performed. First, we used the real data and modeled the effects of 4 CpGs previously found to be associated with TGs in the Genetics of Lipid Lowering Drugs and Diet Network Study (GOLDN). Second, we used the simulated data and modeled the effect of a fictional lipid modifying drug with 5 known causal SNPs and 5 corresponding CpGs. Results: In the real data we show that relationships are present between the CpGs, TGs, and other variables-age, sex, and center. In the simulated data, we show, using linear regression, that no CpGs and only 1 SNP were associated with a change in TG levels, and, using Bayesian network analysis, that relationships are present between the change in TG levels and most SNPs, but not with CpGs. Conclusions: Even when the causal relationships between variables are known, as with the simulated data, if the relationships are not strong then it is challenging to reproduce them in a Bayesian network. PMID- 30275877 TI - Investigating potential causal relationships between SNPs, DNA methylation and HDL. AB - Using data on 680 patients from the GAW20 real data set, we conducted Mendelian randomization (MR) studies to explore the causal relationships between methylation levels at selected probes (cytosine-phosphate-guanine sites [CpGs]) and high-density lipoprotein (HDL) changes (DeltaHDL) using single-nucleotide polymorphisms (SNPs) as instrumental variables. Several methods were used to estimate the causal effects at CpGs of interest on DeltaHDL, including a newly developed method that we call constrained instrumental variables (CIV). CIV performs automatic SNP selection while providing estimates of causal effects adjusted for possible pleiotropy, when the potentially-pleiotropic phenotypes are measured. For CpGs in or near the 10 genes identified as associated with DeltaHDL using a family-based VC-score test, we compared CIV to Egger regression and the two-stage least squares (TSLS) method. All 3 approaches selected at least 1CpG in 2 genes-RNMT;C18orf19 and C6orf141-as showing a causal relationship with DeltaHDL. PMID- 30275878 TI - Direct and indirect genetic effects on triglycerides through omics and correlated phenotypes. AB - Even though there has been great success in identifying lipid-associated single nucleotide polymorphisms (SNPs), the mechanisms through which the SNPs act on each trait are poorly understood. The emergence of large, complex biological data sets in well-characterized cohort studies offers an opportunity to investigate the genetic effects on trait variability as a way of informing the causal genes and biochemical pathways that are involved in lipoprotein metabolism. However, methods for simultaneously analyzing multiple omics, environmental exposures, and longitudinally measured, correlated phenotypes are lacking. The purpose of our study was to demonstrate the utility of the structural equation modeling (SEM) approach to inform our understanding of the pathways by which genetic variants lead to disease risk. With the SEM method, we examine multiple pathways directly and indirectly through previously identified triglyceride (TG)-associated SNPs, methylation, and high-density lipoprotein (HDL), including sex, age, and smoking behavior, while adding in biologically plausible direct and indirect pathways. We observed significant SNP effects (P < 0.05 and directionally consistent) on TGs at visit 4 (TG4) for five loci, including rs645040 (DOCK7), rs964184 (ZPR1/ZNF259), rs4765127 (ZNF664), rs1121980 (FTO), and rs10401969 (SUGP1). Across these loci, we identify three with strong evidence of an indirect genetic effect on TG4 through HDL, one with evidence of pleiotropic effect on HDL and TG4, and one variant that acts on TG4 indirectly through a nearby methylation site. Such information can be used to prioritize candidate genes in regions of interest, inform mechanisms of action of methylation effects, and highlight possible genes with pleiotropic effects. PMID- 30275879 TI - Disentangling associations between DNA methylation and blood lipids: a Mendelian randomization approach. AB - Background: DNA methylation is an epigenetic mechanism that has been proposed as a possible link between genetic and environmental determinants of disease. Prior studies reported robust associations between the methylation of specific cytosine phosphate-guanine (CpG) sites and plasma lipids, namely triglycerides (TGs) and high-density lipoprotein cholesterol (HDL-C). However, the causality of the observed association remains elusive, hampered by weak instrumental variables for methylation status. Aim: We present a novel application of the elastic net approach to implement a bidirectional Mendelian randomization approach to inferring causal relationships between candidate CpGs and plasma lipids in GAW20 data. Methods: We used DNA methylation, TGs, and HDL-C measured during the visit 2. Based on prior findings, we selected 5 methylation markers (cg00574958, cg07504977, cg06690548, cg19693031, and cg03717755) related to TGs, 2 markers (cg09572125 and cg02650017) related to HDL-C, and 2 markers (cg06500161 and cg11024682) related to both traits. We implemented an elastic net approach to improve the selection of the genetic instrument for the methylation markers, followed by bidirectional Mendelian randomization 2-stage least-squares regression. Results: We observed causal effects of blood fasting TGs on the methylation levels of cg00574958 (CPT1A) and cg06690548 (SLC7A11). For cg00574958, our findings were also consistent with the reverse direction of association, that is, from CPT1A methylation to TGs. Conclusions: Current evidence does not rule out either direction of association between the methylation of the cg00574958 CPT1A locus and plasma TGs, highlighting the complexity of lipid homeostasis. We also demonstrated a novel approach to improve instrument selection in DNA methylation studies. PMID- 30275880 TI - Simulation of a medication and methylation effects on triglycerides in the Genetic Analysis Workshop 20. AB - The GAW20 simulation data set is based upon the companion Genetics of Lipid Lowering Drugs and Diet Network (GOLDN) study fenofibrate clinical trial data set that forms the real data example for GAW20. The simulated data problem consists of 200 simulated replications of what might happen if we were to repeat the GOLDN clinical trial 200 independent times, for these exact same subjects, but using a new fictitious drug (called "genomethate") that has a pharmaco-epigenetic effect on triglyceride response. For each replication, the pre-genomethate values at visits 1 and 2 are constant (ie, pedigree structures, age, sex, all phenotypes, covariates, genome-wide association study (GWAS) genotypes, and visit 2 methylation values), the same as the real GOLDN data across all 200 replications. Only the post-genomethate treatment data (ie, methylation and triglyceride levels for visits 3 and 4) change across the 200 replications. We postulate a growth curve pharmaco-epigenetic response model, in which each patient's response to genomethate treatment is individualized, and is dependent upon their genotype as well as the methylation state for key genes. PMID- 30275881 TI - Network analysis of drug effect on triglyceride-associated DNA methylation. AB - Background: DNA methylation, an epigenetic modification, can be affected by environmental factors and thus regulate gene expression levels that can lead to alterations of certain phenotypes. Network analysis has been used successfully to discover gene sets that are expressed differently across multiple disease states and suggest possible pathways of disease progression. We applied this framework to compare DNA methylation levels before and after lipid-lowering medication and to identify modules that differ topologically between the two time points, revealing the association between lipid medication and these triglyceride-related methylation sites. Methods: We performed quality control using beta-mixture quantile normalization on 463,995 cytosine-phosphate-guanine (CpG) sites and deleted problematic sites, resulting in 423,004 probes. We identified 14,850 probes that were nominally associated with triglycerides prior to treatment and performed weighted gene correlation network analysis (WGCNA) to construct pre- and posttreatment methylation networks of these probes. We then applied both WGCNA module preservation and generalized Hamming distance (GHD) to identify modules with topological differences between the pre- and posttreatment. For modules with structural changes between 2 time points, we performed pathway enrichment analysis to gain further insight into the biological function of the genes from these modules. Results: Six triglyceride-associated modules were identified using pretreatment methylation probes. The same 3 modules were not preserved in posttreatment data using both the module-preservation and the GHD methods. Top-enriched pathways for the 3 differentially methylated modules are sphingolipid signaling pathway, proteoglycans in cancer, and metabolic pathways (p values < 0.005). One module in particular included an enrichment of lipid related pathways among the top results. Conclusions: The same 3 modules, which were differentially methylated between pre- and posttreatment, were identified using both WGCNA module-preservation and GHD methods. Pathway analysis revealed that triglyceride-associated modules contain groups of genes that are involved in lipid signaling and metabolism. These 3 modules may provide insight into the effect of fenofibrate on changes in triglyceride levels and these methylation sites. PMID- 30275882 TI - Integrative methylation score to identify epigenetic modifications associated with lipid changes resulting from fenofibrate treatment in families. AB - Epigenome-wide association studies (EWAS) have traditionally focused on the association test of single epigenetic markers with complex traits. However, it is possible that multiple cytosine-phosphate-guanine (CpG) sites at the same locus could jointly exert their effects on human traits. Therefore, a region-based test that combines multiple markers could be more powerful. We used 2 different region based tests to investigate the association between changes in DNA methylation and drug response, including the median methylation level test (MMLT) and sequence kernel association test (SKAT). No genes were found to be significantly associated with the drug response (for triglycerides, the false discovery rate ranged from 0.855 to 0.999; for high-density lipoprotein cholesterol, and the false discovery rate ranged from 0.584 to 0.915). Further evidence is needed to explore potential application of gene-level methylation association analysis. PMID- 30275883 TI - A Bayesian mixed modeling approach for estimating heritability. AB - Background: A Bayesian mixed model approach using integrated nested Laplace approximations (INLA) allows us to construct flexible models that can account for pedigree structure. Using these models, we estimate genome-wide patterns of DNA methylation heritability (h 2 ), which are currently not well understood, as well as h 2 of blood lipid measurements. Methods: We included individuals from the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN) study with Infinium 450 K cytosine-phosphate-guanine (CpG) methylation and blood lipid data pre- and posttreatment with fenofibrate in families with up to three-generation pedigrees. For genome-wide patterns, we constructed 1 model per CpG with methylation as the response variable, with a random effect to model kinship, and age and gender as fixed effects. Results: In total, 425,791 CpG sites pre-, but only 199,027 CpG sites posttreatment were found to have nonzero heritability. Across these CpG sites, the distributions of h 2 estimates are similar in pre- and posttreatment (pre: median = 0.31, interquartile range [IQR] = 0.16; post: median = 0.34, IQR = 0.20). Blood lipid h 2 estimates were similar pre- and posttreatment with overlapping 95% credibility intervals. Heritability was nonzero for treatment effect, that is, the difference between pre- and posttreatment blood lipids. Estimates for triglycerides h 2 are 0.48 (pre), 0.42 (post), and 0.21 (difference); likewise for high-density lipoprotein cholesterol h 2 the estimates are 0.61, 0.68, and 0.10. Conclusions: We show that with INLA, a fully Bayesian approach to estimate DNA methylation h 2 is possible on a genome-wide scale. This provides uncertainty assessment of the estimates, and allows us to perform model selection via deviance information criterion (DIC) to identify CpGs with strong evidence for nonzero heritability. PMID- 30275884 TI - Evidence of batch effects masking treatment effect in GAW20 methylation data. AB - Using the real data set from GAW20, we examined changes in the distribution of DNA methylation before and after treatment. Paired analysis of differences in both mean and variance had grossly inflated type 1 error, suggesting either a very large number of changes across the entire epigenome or major non-biological issues, such as batch effects. Separate analysis of Infinium I and II probes indicated differences in the paired t-test statistics between these two types of probes. Examination of combined principal components showed that the first and fourth principal components discriminate between the before and after treatment measurements, further evidencing the presence of batch effects that make any conclusions about treatment effect suspect. PMID- 30275885 TI - Genome-wide analysis in multiple-case families: assessing the relationship between triglyceride and methylation. AB - The main goal of this paper is to estimate the effect of triglyceride levels on methylation of cytosine-phosphate-guanine (CpG) sites in multiple-case families. These families are selected because they have 2 or more cases of metabolic syndrome (primary phenotype). The methylations at the CpG sites are the secondary phenotypes. Ascertainment corrections are needed when there is an association between the primary and secondary phenotype. We will apply the newly developed secondary phenotype analysis for multiple-case family studies to identify CpG sites where methylations are influenced by triglyceride levels. Our second goal is to compare the performance of the naive approach, which ignores the sampling of the families, SOLAR (Sequential Oligogenic Linkage Analysis Routines), which adjusts for ascertainment via probands, and the secondary phenotype approach. The analysis of possible CpG sites associated with triglyceride levels shows results consistent with the literature when using the secondary phenotype approach. Overall, the secondary phenotype approach performed well, but the comparison of the different approaches does not show significant differences between them. However, for genome-wide applications, we recommend using the secondary phenotype approach when there is an association between primary and secondary phenotypes, and to use the naive approach otherwise. PMID- 30275887 TI - Detection and analysis of CpG sites with multimodal DNA methylation level distributions and their relationships with SNPs. AB - DNA methylation levels at cytosine-phosphate-guanine (CpG) sites with multimodal distributions among different samples have been reported recently. One possible explanation for such variability is that genetic variants might affect epigenetic variation. One obvious case is that mutations such as single-nucleotide polymorphisms (SNPs) interrupt CpG sites, resulting in different DNA methylation levels for different genotypes. However, the relationship between genetic variations and epigenetic differences has not been studied thoroughly, partially because of the lack of powerful and robust methods to survey genome-wide CpG sites with multimodal methylation level distributions (mmCpGs). In this article, we develop a Gaussian mixture-model clustering (GMMC)-based approach to systematically detect all mmCpGs across the genome based on the GAW20 data set. In total, 3785 and 3847 mmCpGs have been identified in pre- and posttreatment data sets, respectively. Result analysis shows that approximately 68 to 70% of mmCpGs detected from unrelated individuals either have direct overlaps with SNPs or have associations with nearby SNPs, suggesting a strong correlation between SNPs and mmCpGs. Comparison with an existing approach illustrates that our GMMC based method is more consistent when the number of samples decreases. In conclusion, mmCpGs may reveal important connections between genetics and epigenetics and they should be carefully identified and evaluated. PMID- 30275886 TI - Data for GAW20: genome-wide DNA sequence variation and epigenome-wide DNA methylation before and after fenofibrate treatment in a family study of metabolic phenotypes. AB - GAW20 provided participants with an opportunity to comprehensively examine genetic and epigenetic variation among related individuals in the context of drug treatment response. GAW20 used data from 188 families (N = 1105) participating in the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN) study (clinicaltrials.gov identifier NCT00083369), which included CD4+ T-cell DNA methylation at 463,995 cytosine-phosphate-guanine (CpG) sites measured before and after a 3-week treatment with fenofibrate, single-nucleotide variation at 906,600 loci, metabolic syndrome components ascertained before and after the drug intervention, and relevant covariates. All GOLDN participants were of European descent, with an average age of 48 years. In addition, approximately half were women and approximately 40% met the diagnostic criteria for metabolic syndrome. Unique advantages of the GAW20data set included longitudinal (3 weeks apart) measurements of DNA methylation, the opportunity to explore the contributions of both genotype and DNA methylation to the interindividual variability in drug treatment response, and the familial relationships between study participants. The principal disadvantage of GAW20/GOLDN data was the spurious correlation between batch effects and fenofibrate effects on methylation, which arose because the pre- and posttreatment methylation data were generated and normalized separately, and any attempts to remove time-dependent technical artifacts would also remove biologically meaningful changes brought on by fenofibrate. Despite this limitation, the GAW20 data set offered informative, multilayered omics data collected in a large population-based study of common disease traits, which resulted in creative approaches to integration and analysis of inherited human variation. PMID- 30275888 TI - Using penalized regression to predict phenotype from SNP data. AB - Background: In a typical genome-enabled prediction problem there are many more predictor variables than response variables. This prohibits the application of multiple linear regression, because the unique ordinary least squares estimators of the regression coefficients are not defined. To overcome this problem, penalized regression methods have been proposed, aiming at shrinking the coefficients toward zero. Methods: We explore prediction of phenotype from single nucleotide polymorphism (SNP) data in the GAW20 data set using a penalized regression approach (LASSO [least absolute shrinkage and selection operator] regression). We use 10-fold cross-validation to assess predictive performance and 10-fold nested cross-validation to specify a penalty parameter. Results: By analyzing approximately 600,000 SNPs we find that, when the sample size comprises a few hundred individuals, SNP effects are heavily penalized, resulting in a poor predictive performance. Increasing the sample size to a few thousand individuals results in a much smaller penalization of the true effects, thus greatly improving the prediction. Conclusions: LASSO regression results in a heavy shrinkage of the regression coefficients, and also requires large sample sizes (several thousand individuals) to achieve good prediction. PMID- 30275889 TI - Transmission-based association mapping of triglyceride levels in a longitudinal framework using quasi-likelihood. AB - Complex genetic traits are often characterized by multiple quantitative phenotypes. Because values of such phenotypes vary over time, it is thought that analyses of longitudinal data on the phenotypes may lead to increased power in detecting genetic association. In this paper, we extend a transmission-based association test applying quasi-likelihood that has been developed by us to the longitudinal framework and to carry out a genome-wide association analysis of triglyceride levels based on the data provided in GAW20. We consider different phenotype definitions based on administration of fenofibrate and obtain significant association findings within genes involved in heart diseases. PMID- 30275890 TI - Analysis of genotype by methylation interactions through sparsity-inducing regularized regression. AB - In this paper, we consider the use of the least absolute shrinkage and selection operator (LASSO)-type regression techniques to detect important genetic or epigenetic loci in genome-wide association studies (GWAS) and epigenome-wide association studies (EWAS). We demonstrate how these techniques can be adapted to provide quantifiable uncertainty using stability selection, including explicit control of the family-wise error rate. We also consider variants of the LASSO, such as the group LASSO, to study genetic and epigenetic interactions. We use these techniques to reproduce some existing results on the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN) data set, which collects from 991 individuals blood triglyceride and differential methylation at 464,000 cytosine phosphate-guanine (CpG) sites and 761,000 single-nucleotide polymorphisms (SNPs), and to identify new research directions. Epigenome-wide and genome-wide models based on the LASSO are considered, as well as an interaction model limited to chromosome 11. The analyses replicate findings concerning 2 CpGs in carnitine palmitoyltransferase 1A (CPT1A). Some suggestions are made regarding potentially interesting directions for the analysis of genetic and epigenetic interactions. PMID- 30275891 TI - Family-based genome-wide association of inflammation biomarkers and fenofibrate treatment response in the GOLDN study. AB - In this paper we analyzed whole-genome genetic information provided by GAW20 from the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN) study for family data. Lipid levels such as triglycerides (TGs) and high-density lipoprotein (HDL) are measured at different time points before and after administration of an anti inflammatory drug fenofibrate. Apart from that, the data contain some covariates and whole-genome genotype information. We propose 2 novel approaches based on Henderson's iterative mixed model to identify associated loci corresponding to (a) inflammatory biomarkers like TGs and HDLs together over time, and (b) the response to fenofibrate treatment. We developed a mixed-model approach using both TG and HDL phenotypes at all 4 time points for a genetic association study whereas we used TGs only to study genetic association with response to the drug. We expect that use of complete family data in a longitudinal framework under a single model involving the appropriate correlation structures would be able to exploit the maximum possible information contained in the sample. Our analysis of whole-genome single nucleotide polymorphisms (SNPs) and genomic regions corresponding to drug treatment finds no significant locus after multiple correction. Arguably, the moderately small sample size of the data set, as compared to the sample size usually used in genome-wide association studies (GWAS), could be a reason for such a result. Nevertheless, we report the top 20 SNPs associated with the phenotypes, and the top 20 SNPs and genomic regions associated with a response to fenofibrate treatment. Application of our methods to larger GWAS and further functional validation of the reported top SNPs and genomic regions might provide important biological insight into the genetic constitution of the trait. PMID- 30275892 TI - Identifying fenofibrate responsive CpG sites. AB - As part of GAW20, we analyzed the familiality and variability of methylation to identify cytosine-phosphate-guanine (CpG) sites responsive to treatment with fenofibrate. Methylation was measured at approximately 450,000 sites in pedigree members, prior to and after 3 weeks of treatment. Initially, we aimed to identify responsive sites by analyzing the pre- and posttreatment methylation changes within individuals, but these data exhibited a confounding treatment/batch effect. We applied an alternative indirect approach by searching for CpG sites whose methylation levels exhibit a genetic response to the drug. We reasoned that these sites would exhibit highly familial and variable methylation levels posttreatment, but not pretreatment. Using a 0.1% threshold, posttreatment sibling correlation (scor) and standard deviation (SD) distributions share 16 outliers, while the corresponding pretreatment distributions share none. Comparing the pre- and posttreatment CpG outliers, 36 (8%) of SD distributions, and 449/450 (nearly 100%) of scor distributions differ. Combined, these results identify methylation sites within the KIAA1804 and ANAPC2 genes. Each gene also has a highly significant methylation quantitative trait locus (meQTL) (KIAA1804: p < 1e-200; ANAPC2: p < 3e-248), indicating that methylation levels at these CpG sites are driven by meQTL and fenofibrate. PMID- 30275893 TI - An efficient analytic approach in genome-wide identification of methylation quantitative trait loci response to fenofibrate treatment. AB - Background: The study of DNA methylation quantitative trait loci (meQTLs) helps dissect regulatory mechanisms underlying genetic associations of human diseases. In this study, we conducted the first genome-wide examination of genetic drivers of methylation variation in response to a triglyceride-lowering treatment with fenofibrate (response-meQTL) by using an efficient analytic approach. Methods: Subjects (n = 429) from the GAW20 real data set with genotype and both pre- (visit 2) and post- (visit 4) fenofibrate treatment methylation measurements were included. Following the quality control steps of removing certain cytosine phosphate-guanine (CpG) probes, the post-/premethylation changes (post/pre) were log transformed and the association was performed on 208,449 CpG sites. An additive linear mixed-effects model was used to test the association between each CpG probe and single nucleotide polymorphisms (SNPs) around +/-1 Mb region, with age, sex, smoke, batch effect, and principal components included as covariates. Bonferroni correction was applied to define the significance threshold (p < 5.6 * 10- 10, given a total of 89,217,303 tests). Finally, we integrated our response meQTL (re-meQTL) findings with the published genome-wide association study (GWAS) catalog of human diseases/traits. Results: We identified 1087 SNPs as cis re meQTLs associated with 610 CpG probes/sites located in 351 unique gene loci. Among these 1087 cis re-meQTL SNPs, 229 were unique and 6 were co-localized at 8 unique disease/trait loci reported in the GWAS catalog (enrichment p = 1.51 * 10- 23). Specifically, a lipid SNP, rs10903129, located in intron regions of gene TMEM57, was a re-meQTL (p = 3.12 * 10- 36) associated with the CpG probe cg09222892, which is in the upstream region of the gene RHCE, indicating a new target gene for rs10903129. In addition, we found that SNP rs12710728 has a suggestive association with cg17097782 (p = 1.77 * 10- 4), and that this SNP is in high linkage disequilibrium (LD) (R2 > 0.8) with rs7443270, which was previously reported to be associated with fenofibrate response (p = 5.00 * 10- 6). Conclusions: By using a novel analytic approach, we efficiently identified thousands of cis re-meQTLs that provide a unique resource for further characterizing functional roles and gene targets of the SNPs that are most responsive to fenofibrate treatment. Our efficient analytic approach can be extended to large response quantitative trait locus studies with large sample sizes and multiple time points data. PMID- 30275894 TI - Analysis of genetic and nongenetic factors influencing triglycerides-lowering drug effects based on paired observations. AB - Obesity is a risk factor for heart disease, stroke, diabetes, high blood pressure, and other chronic diseases. Some drugs, including fenofibrate, are used to treat obesity or excessive weight by lowering the level of specific triglycerides. However, different groups have different drug sensitivities and, consequently, there are differences in drug effects. In this study, we assessed both genetic and nongenetic factors that influence drug responses and stratified patients into groups based on differential drug effect and sensitivity. Our methodology of investigating genetic factors and nongenetic factors is applicable to studying differential effects of other drugs, such as statins, and provides an approach to the development of personalized medicine. PMID- 30275895 TI - Relating drug response to epigenetic and genetic markers using a region-based kernel score test. AB - In GAW20, we investigated the association of specific genetic regions of interest (ROIs) with log-transformed triglyceride (TG) levels following lipid-lowering medication using epigenetic and genetic markers. The goal was to incorporate kernels for cytosine-phosphate-guanine (CpG) markers and compare the kernels to a purely parametric model. Post-treatment TG levels were investigated for post methylation data at CpG sites and region-specific SNPs and adjusted for pre treatment TG levels and age, in independent individuals only (real data: n = 150; simulated data, replicate 84: n = 111). In both data sets, our single-CpG-marker results using kernels and linear regression were in good agreement. In the real data, we investigated the introns of the CPT1A gene previously reported as associated with TG levels as separate ROIs, and were able to find hints of an association of cg17058475 and cg00574958 with post-treatment TG levels. In the simulated data, we investigated a total of 10 regions, in which the 5 causal and 5 non-causal markers lie, respectively, with increased methylation variances, yielding plausible results for the 3 window sizes. Overall, this indicates that kernels for CpG markers are feasible. An interaction regression model for the causal SNP with the nearest CpG marker identified an effect for the SNPs with the three greatest heritabilities simulated. The simulation model assumed full SNP effect only for unmethylated regions decreasing to zero in the case of full methylation. Thus, in the context of a clear candidate setting, interaction between epigenetic and genetic data may enhance information, albeit nominally, even with small sample sizes. Relieving the burden of multiple testing, developing kernels further to analyze data from multiple omics jointly is well warranted. PMID- 30275896 TI - Evaluating the performance of gene-based tests of genetic association when testing for association between methylation and change in triglyceride levels at GAW20. AB - Although methylation data continues to rise in popularity, much is still unknown about how to best analyze methylation data in genome-wide analysis contexts. Given continuing interest in gene-based tests for next-generation sequencing data, we evaluated the performance of novel gene-based test statistics on simulated data from GAW20. Our analysis suggests that most of the gene-based tests are detecting real signals and maintaining the Type I error rate. The minimum p value and threshold-based tests performed well compared to single marker tests in many cases, especially when the number of variants was relatively large with few true causal variants in the set. PMID- 30275897 TI - Reliability of genomic predictions of complex human phenotypes. AB - Genome-wide association studies have helped us identify a wealth of genetic variants associated with complex human phenotypes. Because most variants explain a small portion of the total phenotypic variation, however, marker-based studies remain limited in their ability to predict such phenotypes. Here, we show how modern statistical genetic techniques borrowed from animal breeding can be employed to increase the accuracy of genomic prediction of complex phenotypes and the power of genetic mapping studies. Specifically, using the triglyceride data of the GAW20 data set, we apply genomic-best linear unbiased prediction (G-BLUP) methods to obtain empirical genetic values (EGVs) for each triglyceride phenotype and each individual. We then study 2 different factors that influence the prediction accuracy of G-BLUP for the analysis of human data: (a) the choice of kinship matrix, and (b) the overall level of relatedness. The resulting genetic values represent the total genetic component for the phenotype of interest and can be used to represent a trait without its environmental component. Finally, using empirical data, we demonstrate how this method can be used to increase the power of genetic mapping studies. In sum, our results show that dense genome-wide data can be used in a wider scope than previously anticipated. PMID- 30275898 TI - Genome-wide linkage scan for loci influencing plasma triglyceride levels. AB - We conducted a genome-wide linkage scan to detect loci that influence the levels of fasting triglycerides in plasma. Fasting triglyceride levels were available at 4 time points (visits), 2 pre- and 2 post-fenofibrate intervention. Multipoint identity-by-descent (MIBD) matrices were derived from genotypes using IBDLD. Variance-component linkage analyses were then conducted using SOLAR (Sequential Oligogenic Linkage Analysis Routines). We found evidence of linkage (logarithm of odds [LOD] >=3) at 5 chromosomal regions with triglyceride levels in plasma. The highest LOD scores were observed for linkage to the estimated genetic value (additive genetic component) of the log-normalized triglyceride levels in plasma. Our results suggest that a chromosome 10 locus at 37 cM (LODpre = 3.01, LODpost = 3.72) influences fasting triglyceride levels in plasma regardless of the fenofibrate intervention, and that loci in chromosomes 1 at 170 cM and 4 at 24 cM ceases to affect the triglyceride levels when fenofibrate is present, while the regions in chromosomes 6 at 136 to 162 cM and 11 at 39 to 40 cM appear to influence triglyceride levels in response to fenofibrate. PMID- 30275899 TI - Evaluation of a phenotype imputation approach using GAW20 simulated data. AB - Statistical power, which is the probability of correctly rejecting a false null hypothesis, is a limitation of genome-wide association studies (GWAS). Sample size is a major component of statistical power that can be easily affected by missingness in phenotypic data and restrain the ability to detect associated single-nucleotide polymorphisms (SNPs) with small effect sizes. Although some phenotypes are hard to collect because of cost and loss to follow-up, correlated phenotypes that are easily collected can be leveraged for association analysis. In this paper, we evaluate a phenotype imputation method that incorporates family structure and correlation between multiple phenotypes using GAW20 simulated data. The distribution of missing values is derived using information contained in the missing sample's relatives and additional correlated phenotypes. We show that this imputation method can improve power in the association analysis compared with excluding observations with missing data, while achieving the correct Type I error rate. We also examine factors that may affect the imputation accuracy. PMID- 30275900 TI - Epigenome wide association study of SNP-CpG interactions on changes in triglyceride levels after pharmaceutical intervention: a GAW20 analysis. AB - In the search for an understanding of how genetic variation contributes to the heritability of common human disease, the potential role of epigenetic factors, such as methylation, is being explored with increasing frequency. Although standard analyses test for associations between methylation levels at individual cytosine-phosphate-guanine (CpG) sites and phenotypes of interest, some investigators have begun testing for methylation and how methylation may modulate the effects of genetic polymorphisms on phenotypes. In our analysis, we used both a genome-wide and candidate gene approach to investigate potential single nucleotide polymorphism (SNP)-CpG interactions on changes in triglyceride levels. Although we were able to identify numerous loci of interest when using an exploratory significance threshold, we did not identify any significant interactions using a strict genome-wide significance threshold. We were also able to identify numerous loci using the candidate gene approach, in which we focused on 18 genes with prior evidence of association of triglyceride levels. In particular, we identified GALNT2 loci as containing potential CpG sites that moderate the impact of genetic polymorphisms on triglyceride levels. Further work is needed to provide clear guidance on analytic strategies for testing SNP-CpG interactions, although leveraging prior biological understanding may be needed to improve statistical power in data sets with smaller sample sizes. PMID- 30275901 TI - Identification of epistatic interactions between the human RNA demethylases FTO and ALKBH5 with gene set enrichment analysis informed by differential methylation. AB - The Genetic Analysis Workshop (GAW) presents an opportunity to collaboratively evaluate methodology relevant to current issues in genetic epidemiology. The GAW20 data combine real clinical trial data with fictitious epigenetic drug response endpoints. Considering the evidence suggesting that networks of interactions between many genes underlie complex phenotypes, we utilize differential methylation status to identify a relevant gene set for enrichment analysis and use this to infer potential biological function underlying drug response. We highlight the pertinence of considering the potential for widespread epistatic interactions in the absence of main effects, and present evidence of epistasis between single-nucleotide polymorphisms (SNPs) on the two RNA demethylases FTO and ALKBH5. PMID- 30275902 TI - An adaptive gene-based test for methylation data. AB - DNA methylation plays an important role in normal human development and disease. In epigenome-wide association studies (EWAS), a univariate test for association between a phenotype and each cytosine-phosphate-guanine (CpG) site has been widely used. Given the number of CpG sites tested in EWAS, a stringent significance cutoff is required to adjust for multiple testing; in addition, multiple nearby CpG sites may be associated with the phenotype, which is ignored by a univariate test. These two factors may contribute to the power loss of a univariate test. As an alternative, we propose applying an adaptive gene-based test that is powerful in genome-wide association studies (GWAS), called aSPUw, to EWAS for simultaneous testing on multiple CpG sites within or near a gene. We show its application to the GAW20 methylation data set. PMID- 30275903 TI - Muscle Coordination Control for an Asymmetrically Antagonistic-Driven Musculoskeletal Robot Using Attractor Selection. AB - Recently, numerous musculoskeletal robots have been developed to realize the flexibility and dexterity analogous to human beings and animals. However, because the arrangement of many actuators is complex, the design of the control system for the robot is difficult and challenging. We believe that control methods inspired by living things are important in the development of the control systems for musculoskeletal robots. In this study, we propose a muscle coordination control method using attractor selection, a biologically inspired search method, for an antagonistic-driven musculoskeletal robot in which various muscles (monoarticular muscles and a polyarticular muscle) are arranged asymmetrically. First, muscle coordination control models for the musculoskeletal robot are built using virtual antagonistic muscle structures with a virtually symmetric muscle arrangement. Next, the attractor selection is applied to the control model and subsequently applied to the previous control model without muscle coordination to compare the control model's performance. Finally, position control experiments are conducted, and the effectiveness of the proposed muscle coordination control and the virtual antagonistic muscle structure is evaluated. PMID- 30275904 TI - Restriction-deficient mutants and marker-less genomic modification for metabolic engineering of the solvent producer Clostridium saccharobutylicum. AB - Background: Clostridium saccharobutylicum NCP 262 is a solventogenic bacterium that has been used for the industrial production of acetone, butanol, and ethanol. The lack of a genetic manipulation system for C. saccharobutylicum currently limits (i) the use of metabolic pathway engineering to improve the yield, titer, and productivity of n-butanol production by this microorganism, and (ii) functional genomics studies to better understand its physiology. Results: In this study, a marker-less deletion system was developed for C. saccharobutylicum using the codBA operon genes from Clostridium ljungdahlii as a counterselection marker. The codB gene encodes a cytosine permease, while codA encodes a cytosine deaminase that converts 5-fluorocytosine to 5-fluorouracil, which is toxic to the cell. To introduce a marker-less genomic modification, we constructed a suicide vector containing: the catP gene for thiamphenicol resistance; the codBA operon genes for counterselection; fused DNA segments both upstream and downstream of the chromosomal deletion target. This vector was introduced into C. saccharobutylicum by tri-parental conjugation. Single crossover integrants are selected on plates supplemented with thiamphenicol and colistin, and, subsequently, double-crossover mutants whose targeted chromosomal sequence has been deleted were identified by counterselection on plates containing 5 fluorocytosine. Using this marker-less deletion system, we constructed the restriction-deficient mutant C. saccharobutylicum DeltahsdR1DeltahsdR2DeltahsdR3, which we named C. saccharobutylicum Ch2. This triple mutant exhibits high transformation efficiency with unmethylated DNA. To demonstrate its applicability to metabolic engineering, the method was first used to delete the xylB gene to study its role in xylose and arabinose metabolism. Furthermore, we also deleted the ptb and buk genes to create a butyrate metabolism-negative mutant of C. saccharobutylicum that produces n-butanol at high yield. Conclusions: The plasmid vectors and the method introduced here, together with the restriction-deficient strains described in this work, for the first time, allow for efficient marker less genomic modification of C. saccharobutylicum and, therefore, represent valuable tools for the genetic and metabolic engineering of this industrially important solvent-producing organism. PMID- 30275905 TI - Structural changes in lignocellulosic biomass during activation with ionic liquids comprising 3-methylimidazolium cations and carboxylate anions. AB - Background: Lignocellulosic biomass requires either pretreatment and/or fractionation to recover its individual components for further use as intermediate building blocks for producing fuels, chemicals, and products. Numerous ionic liquids (ILs) have been investigated for biomass pretreatment or fractionation due to their ability to activate lignocellulosic biomass, thereby reducing biomass recalcitrance with minimal impact on its structural components. In this work, we studied and compared 1-allyl-3-methylimidazolium formate ([AMIM][HCOO]) to the commonly used 1-ethyl-3-methylimidazolium acetate ([EMIM][CH3COO]) for its potential to activate hybrid poplar biomass and enable high cellulose and hemicellulose enzymatic conversion. Although [EMIM][CH3COO] has been widely used for activation, [AMIM][HCOO] was recently identified to achieve higher biomass solubility, with an increase of 40% over [EMIM][CH3COO]. Results: Since IL activation is essentially an early stage of IL dissolution, we assessed the recalcitrance of [EMIM][CH3COO] and [AMIM][HCOO]-activated biomass through a suite of analytical tools. More specifically, Fourier transform infrared spectroscopy and X-ray diffraction showed that activation using [AMIM][HCOO] does not deacetylate hybrid poplar as readily as [EMIM][CH3COO] and preserves the crystallinity of the cellulose fraction, respectively. This was supported by scanning electron microscopy and enzymatic saccharification experiments in which [EMIM][CH3COO]-activated biomass yielded almost twice the cellulose and hemicellulose conversion as compared to [AMIM][HCOO]-activated biomass. Conclusion: We conclude that the IL [AMIM][HCOO] is better suited for biomass dissolution and direct product formation, whereas [EMIM][CH3COO] remains the better IL for biomass activation and fractionation. PMID- 30275906 TI - Rapid characterization of the activities of lignin-modifying enzymes based on nanostructure-initiator mass spectrometry (NIMS). AB - Background: Producing valuable fuels and chemicals from lignin is a key factor for making lignocellulosic biomass economically feasible; however, significant roadblocks exist due to our lack of detailed understanding of how lignin is enzymatically depolymerized and of the range of possible lignin fragments that can be produced. Development of suitable enzymatic assays for characterization of putative lignin active enzymes is an important step towards improving our understanding of the catalytic activities of relevant enzymes. Previously, we have successfully built an assay platform based on glycan substrates containing a charged perfluorinated tag and nanostructure-initiator mass spectrometry to study carbohydrate active enzymes, especially various glycosyl hydrolyses. Here, we extend this approach to develop a reliable and rapid assay to study lignin modifying enzymes. Results: Two beta-aryl ether bond containing model lignin dimer substrates, designed to be suitable for studying the activities of lignin modifying enzymes (LMEs) by nanostructure-initiator mass spectrometry (NIMS), were successful synthesized. Small-angle neutron scattering experiments showed that these substrates form micelles in solution. Two LMEs, laccase from the polypore mushroom Trametes versicolor, and manganese peroxidase (MnP) from white rot fungus Nematoloma frowardii, were tested for catalytic activity against the two model substrates. We show that the reaction of laccase and MnP with phenolic substrate yields products that arise from the cleavage of the carbon-carbon single bond between the alpha-carbon and the adjacent aryl carbon, consistent with the mechanism for producing phenoxy radical as reaction intermediates. Reactions of the nonphenolic substrate with laccase, on the other hand, adopt a different pathway by producing an alpha-oxidation product; as well as the cleavage of the beta-aryl ether bond. No cleavage of the carbon-carbon bond between the alpha-carbon and the aryl carbon was observed. To facilitate understanding of reaction kinetics, the reaction time course for laccase activity on the phenolic substrate (I) was generated by the simultaneous measurement of all products at different time points of the reaction. Withdrawal of only a small sample aliquot (0.2 MUL at each time point) ensured minimum perturbation of the reaction. The time course can help us to understand the enzyme kinetics. Conclusions: A new assay procedure has been developed for studying lignin modifying enzymes by nanostructure-initiator mass spectrometry. Enzyme assays of a laccase and a MnP on phenolic and nonphenolic beta-aryl ether substrates revealed different primary reaction pathways due to the availability of the phenoxy radical intermediates. Our assay provides a wealth of information on bond cleavage events not available using conventional colorimetric assays and can easily be carried out in microliter volumes and the quantitative analysis of product formation and kinetics is rapidly achieved by NIMS. This is the first time that NIMS technology was applied to study the activities of lignin-modifying enzymes. Unlike other previous works, our use of amphiphilic guaiacylglycerol beta-O-4 substrate (I) enables the formation of micelles. This approach helps avoid the re-polymerization of the resulting monomeric product. As a result, our assay can clearly demonstrate the degradation pathways of phenolic guaiacylglycerol beta-O-4 type of molecules with laccase and MnP. PMID- 30275907 TI - Enhancement of photosynthetic isobutanol production in engineered cells of Synechocystis PCC 6803. AB - Background: Cyanobacteria, oxygenic photoautotrophic prokaryotes, can be engineered to produce various valuable chemicals from solar energy and CO2 in direct processes. The concept of photosynthetic production of isobutanol, a promising chemical and drop-in biofuel, has so far been demonstrated for Synechocystis PCC 6803 and Synechococcus elongatus PCC 7942. In Synechocystis PCC 6803, a heterologous expression of alpha-ketoisovalerate decarboxylase (Kivd) from Lactococcus lactis resulted in an isobutanol and 3-methyl-1-butanol producing strain. Kivd was identified as a bottleneck in the metabolic pathway and its activity was further improved by reducing the size of its substrate binding pocket with a single replacement of serine-286 to threonine (KivdS286T). However, isobutanol production still remained low. Results: In the present study, we report on how cultivation conditions significantly affect the isobutanol production in Synechocystis PCC 6803. A HCl-titrated culture grown under medium light (50 MUmol photons m-2 s-1) showed the highest isobutanol production with an in-flask titer of 194 mg l-1 after 10 days and 435 mg l-1 at day 40. This corresponds to a cumulative isobutanol production of 911 mg l-1, with a maximal production rate of 43.6 mg l-1 day-1 observed between days 4 and 6. Additional metabolic bottlenecks in the isobutanol biosynthesis pathway were further addressed. The expression level of KivdS286T was significantly affected when co expressed with another gene downstream in a single operon and in a convergent oriented operon. Moreover, the expression of the ADH encoded by codon-optimized slr1192 and co-expression of IlvC and IlvD were identified as potential approaches to further enhance isobutanol production in Synechocystis PCC 6803. Conclusion: The present study demonstrates the importance of a suitable cultivation condition to enhance isobutanol production in Synechocystis PCC 6803. Chemostat should be used to further increase both the total titer as well as the rate of production. Furthermore, identified bottleneck, Kivd, should be expressed at the highest level to further enhance isobutanol production. PMID- 30275909 TI - Complete genome sequence of Kocuria rhizophila BT304, isolated from the small intestine of castrated beef cattle. AB - Background: Members of the species Kocuria rhizophila, belonging to the family Micrococcaceae in the phylum Actinobacteria, have been isolated from a wide variety of natural sources, such as soil, freshwater, fish gut, and clinical specimens. K. rhizophila is important from an industrial viewpoint, because the bacterium grows rapidly with high cell density and exhibits robustness at various growth conditions. However, the bacterium is an opportunistic pathogen involved in human infections. Here, we sequenced and analyzed the genome of the K. rhizophila strain BT304, isolated from the small intestine of adult castrated beef cattle. Results: The genome of K. rhizophila BT304 consisted of a single circular chromosome of 2,763,150 bp with a GC content of 71.2%. The genome contained 2359 coding sequences, 51 tRNA genes, and 9 rRNA genes. Sequence annotations with the RAST server revealed many genes related to amino acid, carbohydrate, and protein metabolism. Moreover, the genome contained genes related to branched chain amino acid biosynthesis and degradation. Analysis of the OrthoANI values revealed that the genome has high similarity (> 97.8%) with other K. rhizophila strains, such as DC2201, FDAARGOS 302, and G2. Comparative genomic analysis further revealed that the antibiotic properties of K. rhizophila vary among the strains. Conclusion: The relatively small number of virulence related genes and the great potential in production of host available nutrients suggest potential application of the BT304 strain as a probiotic in breeding beef cattle. PMID- 30275908 TI - The prevalence of Campylobacter spp. in vegetables, fruits, and fresh produce: a systematic review and meta-analysis. AB - There are a number of reports indicating correlation between outbreaks of campylobacteriosis and the consumption of raw vegetables. This study is a meta analysis on the prevalence of Campylobacter in fresh vegetables and fruits without any location limitation, which was performed through a documented review of the available resources. Relevant literature was reviewed by trained reviewers, who examined the results for the inclusion of articles in the meta analysis. The prevalence of Campylobacter in raw vegetables, the sample source, the Campylobacter species, and the method of detection were extracted. The prevalence of Campylobacter in vegetables, fruits, and fresh produce were estimated to be 0.53%. Analysis of the various sample groups initially showed that the bean and sprouts group was the vegetable with the highest prevalence of Campylobacter (11.08%). The rate of contamination was higher when both the molecular and conventional methods were employed. The highest prevalence of Campylobacter was found in Asia (33.4%). Despite the low prevalence, consumption of raw vegetables is inherently risky because no treatment is used to inactivate the pathogens. Therefore, proper sanitation methods are recommended to treat the raw products. PMID- 30275910 TI - Effects of moderate intensity endurance training vs. high intensity interval training on weight gain, cardiorespiratory capacity, and metabolic profile in postnatal overfed rats. AB - Background: Obesity is associated with several comorbidities, such as cardiovascular disease and type 2 diabetes mellitus, and may have its origin in early life stages, such as in the lactation period, through metabolic programming. Physical activity aids in decreasing the chances of developing cardiovascular and metabolic diseases, even with small weight losses and, in children, can play an essential role in preventing weight gain and other health problems. The present study aimed to evaluate the effects of moderate intensity endurance training and high intensity interval training (HIIT) protocols on obesity-related parameters and cardiorespiratory capacity in overfed Wistar rats throughout the breastfeeding period. Methods: Two days after birth, forty male and female Wistar rats were clustered into two groups: Control Litter Group (CL; ten animals/litter) and Reduced Litter Group (RL; four animals/litter). At weaning, RL animals were distributed randomly into three experimental groups: sedentary, moderate intensity endurance training and HIIT, while CL animals were clustered into a sedentary group. Results: RL male and female body weight, before weaning, was significantly higher when compared with CL animals. This difference was maintained between CLSed and RLSed groups after weaning during all assessed periods. Adiposity was significantly higher in RLSed males when compared to CLSed males, and alterations in glycaemic metabolism were also observed. Endurance and HIIT protocols were efficient in improving maximal cardiorespiratory capacity, as well as concerning the glycemic metabolism and central fat accumulation of males and females submitted to childhood overfeeding by the litter reduction method. Conclusions: Both moderate endurance training and HIIT protocols included in early life were efficient in reverting or preventing certain metabolic alterations as a consequence of overfeeding during breastfeeding in male and female Wistar rats. PMID- 30275911 TI - Pancreatic fat deposition is increased and related to beta-cell function in women with familial partial lipodystrophy. AB - Background: To study pancreatic fat deposition and beta-cell function in familial partial lipodystrophy (FPLD) patients. Methods: In a cross-sectional study, eleven patients with FPLD, and eight healthy volunteers were matched for age and body mass index and studied at a referral center. Body composition was assessed using dual-energy X-ray absorptiometry and the Dixon method of magnetic resonance imaging was used to quantify pancreatic and liver fat. Fasting plasma glucose, insulin, leptin, lipids and homeostasis model assessment of insulin resistance values were measured, and an oral glucose tolerance test was performed. The insulinogenic index, Matsuda insulin sensitivity index and beta-cell disposition index were calculated. Results: The FPLD group presented a higher waist-to-hip ratio and fat mass ratio and lower total, truncal and lower-limb fat masses. Pancreatic and liver fat contents (log transformed) were significantly higher in the FPLD group (5.26 +/- 1.5 vs. 4.08 +/- 0.64, p = 0.034 and 0.77 +/- 0.50 vs. 0.41 +/- 0.18, p = 0.056, respectively). Pancreatic fat was inversely related to the DI (r = - 0.53, p = 0.027) and HDL-cholesterol (r = - 0.63, p = 0.003) and directly related to WHR (r = 0.60; p = 0.009), HbA1c (r = 0.58; p = 0.01) and serum triglyceride (r = 0.48, p = 0.034). Higher triglyceride and lower HDL cholesterol levels were observed in the FPLD group. Conclusions: This study demonstrated for the first time that pancreatic fat deposition is increased in FPLD. Moreover, an inverse relationship was demonstrated between pancreatic fat and beta-cell function. The findings of this study may be consistent with the expandability hypothesis and the twin cycle hypothesis. PMID- 30275912 TI - Multiplexed microRNA Expression Profiling by Combined Asymmetric PCR and Label Free Detection using Silicon Photonic Sensor Arrays. AB - Analysis methods based upon the quantitative, real-time polymerase chain reaction are extremely powerful; however, they face intrinsic limitations in terms of target multiplexing. In contrast, silicon photonic microring resonators represent a modularly multiplexable sensor array technology that is well-suited to the analysis of targeted biomarker panels. In this manuscript we employ an asymmetric polymerase chain reaction approach to selectively amplify copies of cDNAs generated from targeted miRNAs before multiplexed, label-free quantitation through hybridization to microring resonator arrays pre-functionalized with capture sequences. This method, which shows applicability to low input amounts and a large dynamic range, was demonstrated for the simultaneous detection of eight microRNA targets from twenty primary brain tumor samples with expression profiles in good agreement with literature precedent. PMID- 30275913 TI - Bladder Cancer-Specific Nuclear Matrix Proteins-4 May Be a Potential Biomarker for Non-Muscle-Invasive Bladder Cancer Detection. AB - Aims: Bladder cancer-specific nuclear matrix protein-4 (BLCA-4) is a protein expressed mainly in bladder cancer tissues. Therefore, the aim of this study was to investigate its assisting diagnostic potential in non-muscle-invasive bladder cancer (NMIBC). Methods: Twenty patients with NMIBC, 20 with benign prostatic hyperplasia (BPH), and 20 normal controls were included in this study. Blood and urine samples were collected from all patients. Moreover, cancer foci and adjacent tissue samples were collected from NMIBC patients, and normal bladder tissue samples were collected from patients with BPH. A competitive enzyme-linked immunosorbent assay was used to determine the BLCA-4 level in serum and urine, and immunohistochemistry was used to examine BLCA-4 expression in bladder cancer, adjacent, and normal tissues. Results: Median urinary BLCA-4 levels in the NMIBC, BPH, and normal control groups were 0.759 ng/mL, 0.309 ng/mL, and 0.171 ng/mL, respectively. Urinary BLCA-4 level was significantly higher in the NMIBC group than in the other 2 groups (P < 0.01); meanwhile, the BPH group was higher than the normal control group (P < 0.05). Median serum BLCA-4 levels in the NMIBC, BPH, and normal control groups were 5.680 ng/mL, 5.928 ng/mL, and 5.473 ng/mL, respectively, showing no significant difference among groups (P > 0.05). Conclusion: As a new marker of bladder cancer, urinary BLCA-4 level detection might apply for clinical diagnosis or postoperative monitoring for NMIBC. PMID- 30275914 TI - Bimorph piezoelectric vibration energy harvester with flexible 3D meshed-core structure for low frequency vibration. AB - This paper proposes a bimorph piezoelectric vibration energy harvester (PVEH) with a flexible 3D meshed-core elastic layer for improving the output power while lowering the resonance frequency. Owing to the high void ratio of the 3D meshed core structure, the bending stiffness of the cantilever can be lowered. Thus, the deflection of the harvester and the strain in the piezoelectric layer increase. According to vibration tests, the resonance frequency is 15.8% lower and the output power is 68% higher than in the conventional solid-core PVEH. Compared to the solid-core PVEH, the proposed meshed-core PVEH (10 mm * 20 mm * 280 MUm) has 1.3 times larger tip deflection and the maximum output power is 24.6 MUW under resonance condition at 18.7 Hz and 0.2G acceleration. Hence it can be used as a power supply for low-power-consumption sensor nodes in wireless sensor networks. PMID- 30275915 TI - Insights into photovoltaic properties of ternary organic solar cells from phase diagrams. AB - The efficiency of ternary organic solar cells relies on the spontaneous establishment of a nanostructured network of donor and acceptor phases during film formation. A fundamental understanding of phase composition and arrangement and correlations to photovoltaic device parameters is of utmost relevance for both science and technology. We demonstrate a general approach to understanding solar cell behavior from simple thermodynamic principles. For two ternary blend systems we construct and model phase diagrams. Details of EQE and solar cell parameters can be understood from the phase behavior. Our blend system is composed of PC70BM, PBDTTT-C and a near-infrared absorbing cyanine dye. Cyanine dyes are accompanied by counterions, which, in a first approximation, do not change the photophysical properties of the dye, but strongly influence the morphology of the ternary blend. We argue that counterion dissociation is responsible for different mixing behavior. For the dye with a hexafluorophosphate counterion a hierarchical morphology develops, the dye phase separates on a large scale from PC70BM and cannot contribute to photocurrent. Differently, a cyanine dye with a TRISPHAT counterion shows partial miscibility with PC70BM. A large two phase region dictated by the PC70BM: PBDTTT-C mixture is present and the dye greatly contributes to the short-circuit current. PMID- 30275916 TI - Serum Tumor Necrosis Factor-alpha and Interferon-gamma Levels in Pediatric Mycoplasma pneumoniae Pneumonia: A Systematic Review and Meta-Analysis. AB - Background: Mycoplasma pneumoniae pneumonia (MPP) is one of the most common forms of community-acquired pneumonia in children. The objective of this study was to explore potential changes in levels of serum tumor necrosis factor-alpha (TNF alpha) and interferon-gamma (IFN-gamma) associated with pediatric MPP. Methods: This protocol has been registered (PROSPERO 2017: CRD42017077979). A literature search was performed in October 2017 using PubMed, Embase, the Cochrane Library, and other Chinese medical databases to identify studies. The meta-analysis was performed using Review Manager 5.3 software. Random-effect models were used to estimate mean differences (MDs) and 95% confidence intervals (CIs) of cytokine levels. Results: Twelve studies were included in the meta-analysis, encompassing 2,422 children with MPP and 454 healthy control children. Serum TNF-alpha levels were significantly higher in children with MPP compared with healthy children (MD = 22.5, 95% CI = 13.78-31.22, P < 0.00001), and there was significant heterogeneity across studies (I 2 = 100%, P < 0.00001). Subgroup analyses showed no evidence for a difference in serum TNF-alpha levels between children with refractory and nonrefractory MPP. Serum IFN-gamma levels did not significantly differ in children with MPP compared with healthy children (MD = 4.83, 95% CI = 3.27-12.93, P=0.24). Conclusions: Our meta-analysis showed that serum TNF-alpha and IFN-gamma levels were significantly elevated and unchanged, respectively, in pediatric MPP. Because infection by different pathogens has variable effects on serum TNF-alpha and IFN-gamma levels, the finding could be helpful in developing novel diagnostic methods. PMID- 30275917 TI - Helicobacter pylori Infection and Gastric Dysbiosis: Can Probiotics Administration Be Useful to Treat This Condition? AB - Helicobacter pylori (Hp) is responsible for one of the most common infections in the world. The prevalence exceeds 50% of the population in developing countries, and approximately one-third of the adults are colonized in North Europe and North America. It is considered a major pathogenic agent of chronic gastritis, peptic ulcer, atrophic gastritis, gastric cancer, and mucosa-associated lymphoid tissue lymphoma (MALT). Hp colonization modifies the composition of gastric microbiota that could drive the development of gastric disorders. Currently, an emerging problem in Hp treatment is represented by the increasing rate of antimicrobial therapy resistance. In this context, the search for adjuvant agents can be very useful to overcome this issue and probiotics administration can represent a valid option. The aim of this review is to describe the gastric microbiota changes during Hp colonization, the mechanisms of action, and a possible role of probiotics in the treatment of this infection. PMID- 30275918 TI - Pain Reconceptualisation after Pain Neurophysiology Education in Adults with Chronic Low Back Pain: A Qualitative Study. AB - Pain neurophysiology education (PNE) is an educational intervention for patients with chronic pain. PNE purports to assist patients to reconceptualise their pain away from the biomedical model towards a more biopsychosocial understanding by explaining pain biology. This study aimed to explore the extent, and nature, of patients' reconceptualisation of their chronic low back pain (CLBP) following PNE. Eleven adults with CLBP underwent semistructured interviews before and three weeks after receiving PNE. Interviews were transcribed verbatim and thematically analysed in a framework approach using four a priori themes identified from our previous research: (1) degrees of reconceptualisation, (2) personal relevance, (3) importance of prior beliefs, and (4) perceived benefit of PNE. We observed varying degrees of reconceptualisation from zero to almost complete, with most participants showing partial reconceptualisation. Personal relevance of the information to participants and their prior beliefs were associated with the degree of benefit they perceived from PNE. Where benefits were found, they manifested as improved understanding, coping, and function. Findings map closely to our previous studies in more disparate chronic pain groups. The phenomenon of reconceptualisation is applicable to CLBP and the sufficiency of the themes from our previous studies increases confidence in the certainty of the findings.

AB - We report a 7-year-old boy with Menkes disease complicated by rupture of a large splenic artery aneurysm. The aneurysm was successfully embolized with microcoils and n-butyl cyanoacrylate. Further angiographic evaluation revealed marked tortuosity of mesenteric and lower extremity vasculature, including the femoral arteries bilaterally, without aneurysm formation. The patient has since been evaluated annually with computed tomography angiography and there have been no additional vascular complications of his disease during 3-year follow up. PMID- 30275919 TI - Jaw Exercise Therapy and Psychoeducation to Reduce Oral Parafunctional Activities for the Management of Persistent Dentoalveolar Pain. AB - Objective: To retrospectively analyze the effects of our original combination therapy treatment on patients with nonodontogenic persistent dentoalveolar pain. Methods: Twenty-one patients suffering from persistent dentoalveolar pain (nineteen females and two males; mean age +/- standard deviation: 55.7 +/- 19.6 years) participated in this study. They were treated with a therapy combination of jaw exercise and psychoeducation to reduce oral parafunctional activities every month. The intensity of pain in these subjects was evaluated using a numerical rating scale (NRS) before and after treatment. Results: The NRSs at the baseline ranged from 5 to 10 (median, 8), from 0 to 10 (median, 2) at one month after treatment, from 0 to 10 (median, 1) at three months after treatment, and from 0 to 10 (median, 0) at the end of treatment. Pain intensity after treatment improved significantly. Conclusion: There was a significant reduction in pain after our combination of therapies as nonpharmacological treatments, and therefore this treatment could be useful in the management of NPDP patients. PMID- 30275921 TI - Epipericardial fat necrosis: Uncommon cause of acute pleuritic chest pain. AB - Epipericardial fat necrosis (EPFN) is a rare cause for acute chest. We describe the case of a previously healthy 25-year-old man who presented with sudden onset of left-sided chest pain. Laboratory values showed only mildly elevated d-dimer and electrocardiogram was normal. However, subsequent CT angiogram of the chest revealed fat necrosis in the epipericardial fat, characteristic for EPFN, for which the patient was treated with nonsteroidal anti-inflammatory drug. This case highlights the importance of radiologists to consider the prospect of EPFN in the differential diagnosis of acute chest pain as correct diagnosis allows for conservative management and avoidance of more aggressive techniques in symptomatic patients.

AB - Primary lymphoma of bone (PLB) is a rare entity, defined as a lymphoma confined to the bone without evidence of systemic involvement. The disease commonly affects middle-aged to elderly population and it accounts for less than 1% of all malignant lymphomas. We present a case of a 10-year-old child affected by PLB of the forearm and the frontal bone. Characteristic imaging features of PLB and the main differential diagnosis were discussed.

AB - Embolization of subdermally implanted contraceptive devices is a rare but potentially serious event. Timely removal of the embolized foreign body should be considered to prevent possible hemodynamic, respiratory, or hormonal complications. We present a case of a 22-year-old woman with a contraceptive implant embolized to her right lower lobar pulmonary artery, which was successfully managed by endovascular retrieval. PMID- 30275924 TI - Brief Report: Competency-Based Supervision in Motivational Interviewing for Advanced Psychology Trainees: Targeting an A Priori Benchmark. AB - Motivational interviewing (MI) is an evidence based intervention with considerable support for promoting behavior change across a broad range of health and mental health issues. Despite its effectiveness, challenges associated with learning the approach may limit its full implementation in many clinical settings. The aim of the present study was to evaluate a supervised MI training practicum implemented within a doctoral internship/postdoctoral fellowship training Program. The goal of the practicum was to enable each trainee to achieve expert competence in MI. Participants were 29 psychology doctoral interns and 1 postdoctoral fellow who participated in the training as part of their internship or fellowship program. Training included an initial workshop followed by a supervised practicum during which progress towards an a priori established expert competence benchmark was tracked through the use of an established coding system. Results indicated that trainees were satisfied with the supervision received. Three trainees did not achieve the a priori benchmark due to schedule conflicts. The 27 trainees who achieved the benchmark required between 4 and 20 supervision sessions to do so (mean = 9.22, SD = 3.77). With the exception of reflective listening skill, prior training, baseline skill, and self-reported motivation were not associated with number of supervision sessions required to achieve the benchmark. Implications for training and dissemination of MI in clinical settings are discussed. PMID- 30275926 TI - Corrigendum: Elderly woman with soft tissue ossification.

PMID- 30275925 TI - The Provision of Urban Ecosystem Services Throughout the Private-Social-Public Domain: A Conceptual Framework. AB - As cities are largely private systems, recent investigations have assessed the provision of ecosystem services from the private realm. However, these assessments are largely based on the concept of ownership and fail to capture the complexity of service provision mediated by interactions between people and ecological structures. In fact, people interact with ecological structures in their role of land tenants and stewards, further modulating the provision of ecosystem services. We devise a theoretical framework based on the concepts of ownership, tenancy, and stewardship, in which people, as mediators of ecosystem services, regulate the provision of services throughout the private-social-public domain. We survey relevant literature describing these dimensions and propose a comprehensive framework focused on the private-social-public domain. Our framework can advance ecosystem service research and enhance the provision of ecosystems services. The inclusion of people's individual, social and public roles in the mediation of ecosystem services could improve how benefits are planned for, prioritized, and optimized across cities. PMID- 30275927 TI - How well are aid agencies evaluating programs? An assessment of the quality of global health evaluations. AB - Evaluations are key to learning and accountability. We assessed the methodological quality of 37 randomly selected programme evaluations from 5 major global health funders. Two researchers rated each evaluation for relevance, validity, and reliability and met to resolve discrepancies. Most evaluations asked questions relevant to the health programme, but less than 40 per cent of impact evaluations and less than 10 per cent of performance evaluations used relevant data, followed accepted social science methods for sampling, or had high analytical validity and reliability. There is a need to improve the methodological quality of programme evaluations. PMID- 30275928 TI - First cytogenetic analysis of lesser gymnures (Mammalia, Galericidae, Hylomys) from Vietnam. AB - Gymnures are an ancient group of small insectivorous mammals and are characterized by a controversial taxonomic status and the lack of a description of karyotypes for certain species. In this study, conventional cytogenetic techniques (Giemsa, CBG- and GTG-banding, Ag-NOR), CMA3-DAPI staining, and fluorescent in situ hybridization (FISH) with telomeric DNA probes were used to examine for the first time the karyotypes of lesser gymnures of group Hylomyssuillus Muller, 1840 from northern and southern Vietnam. All studied specimens had karyotypes with 2n=48, NFa=64. C-positive heterochromatic blocks existed in centromeric regions of 7 bi-armed autosomes and the submetacentric X chromosome. The Y chromosome is a C-positive and dot-like. The nucleolus organizer regions resided terminally on the short arms of 2 small bi-armed pairs. Positive signals at the telomeres of all chromosomes were revealed by FISH. CMA3 positive blocks were localized on the telomeric and pericentric regions of most bi-armed and acrocentric chromosomes. Despite the large genetic distances between Hylomys Muller, 1840, lesser gymnures from H.suillus-group from northern and southern Vietnam have similar karyotypic characteristics. PMID- 30275929 TI - Cytogenetic studies in three octopods, Octopusminor, Amphioctopusfangsiao, and Cistopuschinensis from the coast of China. AB - To provide markers to identify chromosomes in the genome of octopods, chromosomes of three octopus species were subjected to NOR/C-banding. In addition, we examined their genome size (C value) to submit it to the Animal Genome Size Database. Silver staining revealed that the number of Ag-nucleoli was 2 (Octopusminor (Sasaki, 1920)), 2 (Amphioctopusfangsiao (d'Orbigny, 1839)) and 1 (Cistopuschinensis Zheng et al., 2012), respectively, and the number of Ag nucleoli visible was the same as that of Ag-NORs on metaphase plates in the same species. In all analyzed metaphases, Ag-NORs were mainly located terminally on the long arms of chromosomes 3 (3rd) of O.minor and on the short arms of chromosomes 4 (4th) of A.fangsiao, whereas only one of the chromosomes 23 (23rd) was found Ag-NORs of C.chinensis. C-bands were localized predominantly in the centromeric regions of chromosomes in the three species, while other conspicuous stable C-bands were observed in terminal regions, including the Ag-NORs. That means these three chromosome pairs (3rd, 4th and 23rd) could be considered species-specific cytogenetic markers. The mean C values of O.minor, A.fangsiao and C.chinensis were 7.81+/-0.39 pg (0.070 pg per unit length), 8.31+/-0.18 pg (0.068 pg per unit length) and 5.29+/-0.10 pg (0.038 pg per unit length), respectively, and results showed that C values of the three species were not proportional to the relative length of the chromosomes. These cytogenetic characteristics will provide more theoretical foundation for further researches on chromosome evolution in octopods. PMID- 30275930 TI - New chromosome counts and genome size estimates for 28 species of Taraxacum sect. Taraxacum. AB - The species-rich and widespread genus Taraxacum F. H. Wiggers, 1780 (Asteraceae subfamily Cichorioideae) is one of the most taxonomically complex plant genera in the world, mainly due to its combination of different sexual and asexual reproduction strategies. Polyploidy is usually confined to apomictic microspecies, varying from 3x to 6x (rarely 10x). In this study, we focused on Taraxacum sect. Taraxacum (= T.sect.Ruderalia; T.officinale group), i.e., the largest group within the genus. We counted chromosome numbers and measured the DNA content for species sampled in Central Europe, mainly in Czechia. The chromosome number of the 28 species (T.aberrans Hagendijk, Soest & Zevenbergen, 1974, T.atroviride Stepanek & Travnicek, 2008, T.atrox Kirschner & Stepanek, 1997, T.baeckiiforme Sahlin, 1971, T.chrysophaenum Railonsala, 1957, T.coartatum G.E.

PMID- 30275931 TI - Nanoscale inhibition of polymorphic and ambidextrous IAPP amyloid aggregation with small molecules. AB - Understanding how small molecules interface amyloid fibrils on the nanoscale is of importance for developing therapeutic treatment against amyloid-based diseases. Here we show, for the first time, that human islet amyloid polypeptide (IAPP) in the fibrillar form is polymorphic and ambidextrous possessing multiple periodicities. Upon interfacing with small molecule epigallocatechin gallate (EGCG), IAPP aggregation was rendered off pathway assuming the form of soft and disordered clusters, while mature IAPP fibrils displayed kinks and branching but conserved the twisted fibril morphology. These nanoscale phenomena resulted from competitive interactions between EGCG and the IAPP amyloidogenic region, as well as end capping of the fibrils by the small molecule. This information is crucial to delineating IAPP toxicity implicated in type 2 diabetes and developing new inhibitors against amyloidogenesis. PMID- 30275932 TI - Perceived control and avoidance in posttraumatic stress. AB - Despite much evidence concerning the importance of control over stressors in animal models of adaptation to stress, there is a dearth of experimental evidence for the role of controllability in posttraumatic stress disorder (PTSD). This study investigated whether perceived control over aversive stimuli influenced subsequent avoidance in a female community sample with and without PTSD symptomatology. Female participants (N = 145) with high or low PTSD symptoms were randomized to receive instructions indicating either controllable or uncontrollable offset of aversive, positive, and neutral images; despite this perception, the actual duration of presentations was standardized in both conditions. Participants subsequently completed an emotional avoidance task. There was a significant group * condition interaction effect, such that those with PTSD symptoms who were told they lacked control displayed greater avoidance of the subsequent stressor relative to those told they had control. This pattern was not observed in those without PTSD symptoms. This finding suggests that ongoing experiences of uncontrollability may heighten psychological vulnerabilities implicated in PTSD. PMID- 30275933 TI - Memory for neutral, emotional and trauma-related information in sexual abuse survivors. AB - Previous studies have shown that trauma-exposed individuals, including survivors of sexual abuse, show inferior performance in episodic memory tasks compared to non-exposed controls. This, however, has mainly been tested using neutral content. Our goal in this study was to determine whether this relative impairment in episodic memory extends to generally emotional and trauma-related content. Twenty-seven sexual abuse survivors and 27 control women participated in the study. They listened to stories with three content types (neutral, generally emotional and trauma-related) and performed a free-recall task immediately and 30 minutes later. Sexual abuse survivors showed poorer recall of neutral material compared to control participants. Lower recall was also observed for generally emotional content. However, importantly, there was no difference between groups in the recall of trauma-related content. The main novel contribution of this study is the demonstration that verbal episodic memory is not impaired for non autobiographical trauma-related content in sexual abuse survivors. We discuss how this could be explained by personal relevance and attentional capture. PMID- 30275934 TI - A programme for the prevention of post-traumatic stress disorder in midwifery (POPPY): indications of effectiveness from a feasibility study. AB - Background: Midwives can experience events they perceive as traumatic when providingcare. As a result, some will develop post-traumatic stress disorder (PTSD), with adverse implications for their mental health, the quality of care provided for women and the employing organizations. POPPY (Programme for the prevention of PTSD in midwifery) is a package of educational and supportive resources comprising an educational workshop, information leaflet, peer support and access to trauma-focused clinical psychology intervention. A feasibility study of POPPY implementation was completed. Objective: This study aimed to identify potential impacts of POPPY on midwives' understandingof trauma, their psychological well-being and job satisfaction. Method: POPPY was implemented in one hospital site. Before taking part in the POPPY workshop (T1) midwives (N = 153) completed self-report questionnaires, which measured exposure to work related trauma, knowledge and confidence of managing trauma responses, professional impacts, symptoms of PTSD, burnout and job satisfaction. Measures were repeated (T2) approximately 6 months after training (n = 91, 62%). Results: Midwives' confidence in recognizing (p = .001) and managing early traumaresponses in themselves and their colleagues significantly improved (both p < .001). There was a trend towards reduced levels of PTSD symptomatology, and fewer midwives reported sub clinical levels of PTSD (from 10% at T1 to 7% at T2). The proportion of midwives reporting high and moderate levels of depersonalization towards care was reduced (33% to 20%) and midwives reported significantly higher levels of job satisfaction at T2 (p < .001). Reductions in self-reported stress-related absenteeism (12% to 5%), long-term changes to clinical allocation (10% to 5%) and considerations about leaving midwifery (34% to 27%) were identified. Conclusions: In conclusion, POPPY shows very positive potential to improve midwives' mental health and the sensitivity of care they provide, and reduce service disruption and costs for trusts. Large-scale longitudinal evaluation is required. PMID- 30275936 TI - Machine Learning Methods for Histopathological Image Analysis.

PMID- 30275935 TI - FoldX as Protein Engineering Tool: Better Than Random Based Approaches? AB - Improving protein stability is an important goal for basic research as well as for clinical and industrial applications but no commonly accepted and widely used strategy for efficient engineering is known. Beside random approaches like error prone PCR or physical techniques to stabilize proteins, e.g. by immobilization, in silico approaches are gaining more attention to apply target-oriented mutagenesis. In this review different algorithms for the prediction of beneficial mutation sites to enhance protein stability are summarized and the advantages and disadvantages of FoldX are highlighted. The question whether the prediction of mutation sites by the algorithm FoldX is more accurate than random based approaches is addressed. PMID- 30275937 TI - A Review of Matched-pairs Feature Selection Methods for Gene Expression Data Analysis. AB - With the rapid accumulation of gene expression data from various technologies, e.g., microarray, RNA-sequencing (RNA-seq), and single-cell RNA-seq, it is necessary to carry out dimensional reduction and feature (signature genes) selection in support of making sense out of such high dimensional data. These computational methods significantly facilitate further data analysis and interpretation, such as gene function enrichment analysis, cancer biomarker detection, and drug targeting identification in precision medicine. Although numerous methods have been developed for feature selection in bioinformatics, it is still a challenge to choose the appropriate methods for a specific problem and seek for the most reasonable ranking features. Meanwhile, the paired gene expression data under matched case-control design (MCCD) is becoming increasingly popular, which has often been used in multi-omics integration studies and may increase feature selection efficiency by offsetting similar distributions of confounding features. The appropriate feature selection methods specifically designed for the paired data, which is named as matched-pairs feature selection (MPFS), however, have not been maturely developed in parallel. In this review, we compare the performance of 10 feature-selection methods (eight MPFS methods and two traditional unpaired methods) on two real datasets by applied three classification methods, and analyze the algorithm complexity of these methods through the running of their programs. This review aims to induce and comprehensively present the MPFS in such a way that readers can easily understand its characteristics and get a clue in selecting the appropriate methods for their analyses. PMID- 30275938 TI - Engineering mesenchymal stem cells to improve their exosome efficacy and yield for cell-free therapy. AB - Through traditional medicine, there were diseases and disorders that previously remained untreated or were simply thought to be incurable. Since the discovery of mesenchymal stem cells (MSCs), there has been a flurry of research to develop MSC based therapy for diseases and disorders. It is now well-known that MSCs do not typically engraft after transplantation and exhibit their therapeutic effect via a paracrine mechanism. In addition to secretory proteins, MSCs also produce extracellular vesicles (EVs), membrane-bound nanovesicles containing proteins, DNA and RNA. The secreted vesicles then interact with target cells and deliver their contents, imparting their ultimate therapeutic effect. Unlike the widely studied cancer cells, the yield of MSC-exosomes is a limiting factor for large scale production for cell-free therapies. Here we summarise potential approaches to increase the yield of such vesicles while maintaining or enhancing their efficacy by engineering the extracellular environment and intracellular components of MSCs. PMID- 30275940 TI - Breaking bad news protocol for cancer disclosure: an Iranian version. AB - In Iran, as in many Asian and Middle Eastern countries, a significant proportion of cancer patients are never informed of their illness. One solution that has been proposed to tackle this challenge is to develop a localized protocol on cancer diagnosis disclosure based on the culture and values of community members, and train healthcare team members to deliver the bad news using this protocol. This article introduces a localized protocol for disclosure of bad news to cancer patients in Iran. This protocol consists of six steps, including assessment, planning, preparation, disclosure, support and conclusion. In the drafting of this protocol an attempt was made to meticulously consider the cultural features of the Iranian society. Although breaking bad news will never be easy, having an appropriate plan of action based on individual's attitudes, considerably helps health-care professionals, and provides more satisfaction in patients.

AB - Background: Schizophrenia negative symptoms (SNS) contribute substantially to poor functional outcomes, loss in productivity and poor quality of life. It is unclear which instruments may be used for assessing quality of life in patients with SNS. Objective: The objective of this review was to identify instruments assessing health-related quality of life (HRQoL) validated in patients with SNS and to assess their level of validation. Data sources: We conducted a systematic literature review in Medline and the ISPOR database in March 2016 to identify studies on the quality of life in patients with SNS published by March 2016. Data extraction: Psychometric properties and validation steps. Data synthesis: After applying inclusion/exclusion criteria, 49 studies were selected for the analysis of HRQoL instruments; however, none of these instruments only addressed patients with SNS. Of these, 19 HRQoL instruments used in patients with schizophrenia or including patients with SNS among others, in the context of instrument validation, were identified (4 generic, 10 non-specific mental health, 5 schizophrenia-specific). Conclusion: No HRQoL instrument has been validated in patients with SNS only; for the remaining instruments identified, it remains unclear whether they were intended to capture HRQoL in patients with SNS.

Histopathologic observation of temporal bones showed bilateral small glomus tympanicum tumors limited to the promontory. Although there was bilateral tinnitus, there was no pulsatile tinnitus, no conductive hearing loss and both of the tympanic membranes were intact. Histopathologic observation of temporal bones after death showed bilateral glomus tympanicum tumors. To our knowledge, this is the first reported case of bilateral glomus tympanicum tumors. PMID- 30275942 TI - SYNE1-related autosomal recessive cerebellar ataxia, congenital cerebellar hypoplasia, and cognitive impairment. AB - The spectrin repeat-containing nuclear envelope protein 1 (SYNE1) gene encodes a family of spectrin structural proteins that are associated with anchoring the plasma membrane to the actin cytoskeleton. SYNE1-related disease is most commonly reported in autosomal recessive spinocerebellar ataxia 8, which demonstrates variable age of onset with a median of 30 years of age. However pathogenic mutations in SYNE1 are also causative of arthrogryposis multiplex congenital, a severe congenital neuromuscular condition. Here in we report monozygous twins with childhood onset ataxia, cerebellar hypoplasia, dysarthria, and cognitive impairment sharing two novel heterozygous mutations in the SYNE1 gene. Our family may expand the clinical phenotype associated with SYNE1-related disease and offers possible genotype-phenotype correlations of a rare continuum of clinical disease phenotypes from neonatal to adult onset.

PMID- 30275945 TI - Incidence and outcomes of multidrug-resistant gram-negative bacteria infections in intensive care unit from Nepal- a prospective cohort study. AB - Background: Infections caused by multi-drug resistant gram-negative bacterial infections are the principle threats to the critically ill patients of intensive care units. Increasing reports of these infections from the Nepalese intensive care unit underline the clinical importance of these pathogens. However, the impact of these infections on the patient's clinical outcome has not yet been clearly evaluated. The objective of our study was to determine the incidence and associated clinical outcome of multi-drug resistant gram-negative bacterial infections in intensive care unit from a tertiary care center of Nepal. Methods: A prospective cohort study was conducted among adult patients admitted in intensive care unit of B. P Koirala Institute of Health Sciences from July to December 2017. Patients infected with multi-drug resistant gram-negative bacteria, non-multi-drug resistant gram-negative bacteria and those without infection were included. Identification of gram-negative bacteria and their antibiotic susceptibility pattern was performed with standard microbiological methods. Demographic, clinical profiles and outcomes (in-hospital-mortality, intensive care unit and hospital length of stay) were documented. Results: The incidence rate of multi-drug resistant gram-negative bacteria infections was 47 per 100 admitted patients (64/137) with 128 episodes. Acinetobacter species (41%, 52/128) was the commonest followed by Klebsiella pneumoniae (28%, 36/128) and Pseudomonas spp (21%, 27/128). Patients with multi-drug resistant gram-negative bacteria in comparison to non-multi-drug resistant gram-negative bacteria had high healthcare-associated infections (95%, 61/64 versus 20%, 2/10; p = < 0.001). In-hospital-mortality was 38% (24/64), 20% (2/10) and 10% (4/41) in multi-drug resistant, non-multi-drug resistant and uninfected group respectively (p = 0.007). After adjustment for independent risk factors, compared to uninfected patients, the odds ratio (CI) for in-hospital-mortality in multi-drug resistant and non-multi-drug resistant group was (4.7[1.4-15.5], p = 0.01) and 2.60 [0.38 17.8], p = 0.32) respectively. Multi-drug resistant patients also had longer intensive care unit and hospital stay, however, it was statistically insignificant. Conclusion: The incidence of multi-drug resistant gram-negative bacterial infections was remarkably high in our intensive care unit and showed a significant association with healthcare-associated infections and in-hospital mortality. PMID- 30275944 TI - Deep analysis of immune response and metabolic signature in children with food protein induced enterocolitis to cow's milk. AB - Background: Food Protein-Induced Enterocolitis Syndrome (FPIES) is considered to be a non-IgE mediated food allergy. However, its pathogenesis remains poorly understood and biomarkers are lacking. We aimed to perform in-depth characterization of humoral and cellular immune responses in children with cow's milk (CM)-FPIES and investigated whether there is a FPIES metabolomic signature. Methods: Children with CM-FPIES and control subjects with an IgE-mediated CM allergy (IgE-CMA), both avoiding CM, were recruited on the day of an oral food challenge. Blood samples were collected before the challenge. Total and specific levels of IgE, IgG1-4, IgA, IgM and IgD to various whey and casein allergens and to their gastroduodenal digestion products were measured in plasma, using plasma from CM-tolerant peanut allergic patients (IgE-PA, not avoiding CM) as additional controls. Cytokine secretion and cellular proliferation were analyzed after stimulation of PBMC with different CM allergens. Metabolomic profiles were obtained for plasma samples using liquid chromatography coupled to high resolution mass spectrometry. Results: Nine children with CM-FPIES and 12 control subjects (6 IgE-CMA and 6 IgE-PA) were included. In children with CM-FPIES, total Ig concentrations were lower than in control subjects, specific Ig against CM components were weak to undetectable, and no specific IgE against CM digestion products were detected. Moreover, in CM-FPIES patients, we did not find any Th cell proliferation or associated cytokine secretion after allergen reactivation, whereas such responses were clearly found in children with IgE-CMA. Plasma metabolic profiles were different between CM allergic patients, with significantly lower concentrations of various fatty acids and higher concentrations of primary metabolites such as amino acids in CM-FPIES compared to IgE-CMA patients. Conclusions: In CM-FPIES, both humoral and cellular specific immune responses are weak or absent, and this is not related to CM avoidance. A metabolomic signature was identified in patients with CM-FPIES that may be useful for the diagnosis and management of this disease. PMID- 30275946 TI - Wireless whispering-gallery-mode sensor for thermal sensing and aerial mapping. AB - The Internet of Things (IoT)1,2 employs a large number of spatially distributed wireless sensors to monitor physical environments, e.g., temperature, humidity, and air pressure, and has many applications, including environmental monitoring3, health care monitoring4, smart cities5, and precision agriculture. A wireless sensor can collect, analyze, and transmit measurements of its environment1,2. Currently, wireless sensors used in the IoT are predominately based on electronic devices that may suffer from electromagnetic interference in many circumstances. Being immune to the electromagnetic interference, optical sensors provide a significant advantage in harsh environments6. Furthermore, by introducing optical resonance to enhance light-matter interactions, optical sensors based on resonators exhibit small footprints, extreme sensitivity, and versatile functionalities7,8, which can significantly enhance the capability and flexibility of wireless sensors. Here we provide the first demonstration of a wireless photonic sensor node based on a whispering-gallery-mode (WGM) optical resonator, in which light propagates along the circular rim of such a structure like a sphere, a disk, or a toroid by continuous total internal reflection. The sensor node is controlled via a customized iOS app. Its performance was studied in two practical scenarios: (1) real-time measurement of the air temperature over 12 h and (2) aerial mapping of the temperature distribution using a sensor node mounted on an unmanned drone. Our work demonstrates the capability of WGM optical sensors in practical applications and may pave the way for the large-scale deployment of WGM sensors in the IoT. PMID- 30275947 TI - Optical conductivity-based ultrasensitive mid-infrared biosensing on a hybrid metasurface. AB - Optical devices are highly attractive for biosensing as they can not only enable quantitative measurements of analytes but also provide information on molecular structures. Unfortunately, typical refractive index-based optical sensors do not have sufficient sensitivity to probe the binding of low-molecular-weight analytes. Non-optical devices such as field-effect transistors can be more sensitive but do not offer some of the significant features of optical devices, particularly molecular fingerprinting. We present optical conductivity-based mid infrared (mid-IR) biosensors that allow for sensitive and quantitative measurements of low-molecular-weight analytes as well as the enhancement of spectral fingerprints. The sensors employ a hybrid metasurface consisting of monolayer graphene and metallic nano-antennas and combine individual advantages of plasmonic, electronic and spectroscopic approaches. First, the hybrid metasurface sensors can optically detect target molecule-induced carrier doping to graphene, allowing highly sensitive detection of low-molecular-weight analytes despite their small sizes. Second, the resonance shifts caused by changes in graphene optical conductivity is a well-defined function of graphene carrier density, thereby allowing for quantification of the binding of molecules. Third, the sensor performance is highly stable and consistent thanks to its insensitivity to graphene carrier mobility degradation. Finally, the sensors can also act as substrates for surface-enhanced infrared spectroscopy. We demonstrated the measurement of monolayers of sub-nanometer-sized molecules or particles and affinity binding-based quantitative detection of glucose down to 200 pM (36 pg/mL). We also demonstrated enhanced fingerprinting of minute quantities of glucose and polymer molecules. PMID- 30275948 TI - Nutrition and listeriosis during pregnancy: a systematic review. AB - Listeriosis is a rare but severe foodborne illness which is more common in populations such as pregnant women, and can result in serious complications including miscarriage, prematurity, maternal and neonatal sepsis, and death in the newborn. Population recommendations exist for specific foods and food preparation practices to reduce listeriosis risk during pregnancy. The aim of the present systematic review was to assess the association between listeriosis and these practices during pregnancy to confirm appropriateness of these recommendations. We searched MEDLINE, Embase, CINAHL Plus, Web of Science Core Collection, included articles' references, and contacted clinical experts. All databases were searched until July 2017. Case-control and cohort studies were included which assessed pregnant women or their newborn offspring with known listeriosis status and a nutritional exposure consistent with international population recommendations for minimising listeriosis. Outcomes included listeriosis with or without pregnancy outcomes. Risk of bias was assessed through the Newcastle-Ottawa Scale. Results were described narratively due to clinical heterogeneity in differences in nutritional exposures. Eleven articles comprising case-control or cross-sectional studies met the inclusion criteria. Cases of maternal, fetal or neonate listeriosis were more likely to have consumed high risk dairy products, meat products or some fruits during pregnancy in comparison with women without listeriosis. Cases of listeriosis were more likely to have consumed foods that are highlighted in population guidelines to avoid to minimise listeriosis in comparison with those without listeriosis during pregnancy. Further research is warranted assessing means of improving the reach, uptake and generalisability of population guidelines for reducing listeriosis during pregnancy. PMID- 30275949 TI - Laparoscopic Roux-en-Y gastric bypass is as safe as laparoscopic sleeve gastrectomy. Results of a comparative cohort study. AB - Background: A meta-analysis and six randomized controlled trials show higher 30 day complication rates with laparoscopic Roux-en-Y gastric bypass (LRYGB) than with laparoscopic sleeve gastrectomy (LSG). Aim: To identify any difference in 30 day outcomes of patients treated with LRYGB or LSG when a standardized technique and identical post-operative protocol was followed with all procedures being conducted either by or under the supervision of a single consultant surgeon who had significant experience in bariatric surgery prior to commencing independent practice. Methods: A prospectively collected database of all patients under primary LRYGB or LSG, between March 2010 and February 2017, was analyzed. Data on demographics, length-of-stay (LOS), conversion to open, 30-day complications and mortality were reviewed. Results: Over a seven-year period, 485 patients (LRYGB 279 and LSG-206) were included. There were no significant demographic differences and no difference in the pre-operative risk scoring [American Society of Anesthesiologists (ASA) and obesity surgery mortality risk score (OSMRS)] between the groups. There was no significant difference between the groups in terms of LOS (p = 0.275), complications (p = 0.920), re-admissions (p = 0.593) or re operations (p = 0.366) within 30-days. There were no conversions to open or in patient mortality in either group. Conclusions: Unlike previous studies, we found no difference in early complication rates between LRYGB and LSG in a comparable cohort when performed by a surgeon with sufficient experience in bariatric surgery. PMID- 30275950 TI - Protein interaction and functional data indicate MTHFD2 involvement in RNA processing and translation. AB - Background: The folate-coupled metabolic enzyme MTHFD2 is overexpressed in many tumor types and required for cancer cell proliferation, and is therefore of interest as a potential cancer therapeutic target. However, recent evidence suggests that MTHFD2 has a non-enzymatic function which may underlie the dependence of cancer cells on this protein. Understanding this non-enzymatic function is important for optimal targeting of MTHFD2 in cancer. Methods: To identify potential non-enzymatic functions of MTHFD2, we defined its interacting proteins using co-immunoprecipitation and mass spectrometry and integrated this information with large-scale co-expression analysis, protein dynamics, and gene expression response to MTHFD2 knockdown. Results: We found that MTHFD2 physically interacts with a set of nuclear proteins involved in RNA metabolism and translation, including components of the small ribosomal subunit and multiple members of the RNA-processing hnRNP family. Interacting proteins were also in general co-expressed with MTHFD2 in experiments that stimulate or repress proliferation, suggesting a close functional relationship. Also, unlike other folate one-carbon enzymes, the MTHFD2 protein has a short half-life and responds rapidly to serum. Finally, shRNA against MTHFD2 depletes several of its interactors and yields an overall transcriptional response similar to targeted inhibition of certain ribosomal subunits. Conclusions: Taken together, our findings suggest a novel function of MTHFD2 in RNA metabolism and translation. PMID- 30275951 TI - Predictors of mortality among under-five children with severe acute malnutrition, Northwest Ethiopia: an institution based retrospective cohort study. AB - Background: Globally, approximately 19 million children under 5 years are suffering from Severe Acute Malnutrition (SAM). It is a major cause of morbidity and mortality in low-income countries including Ethiopia. However, little is known regarding predictors of mortality among these children in Ethiopia. The current study aimed to assess the potential predictors of mortality among under five children with SAM admitted to a stabilization center. Method: A retrospective cohort study was conducted in 527 under-five children who were admitted for SAM at the University of Gondar comprehensive specialized hospital from 2014 to 2016. Data were collected from a randomly selected chart after getting ethical clearance. Data were cleaned, coded and entered to Epi-info (version 7) and analyzed using STATA (version14). The outcome was computed by using tables and graphs. A multivariable cox proportional hazards model was fitted to identify predictors of mortality. Result: Overall, the median follow-up period was 10 days with interquartile range (Q1, Q3: 8, 17). At the end of the follow-up, the mortality rate was 66(12.52%). Anemia (AHR(Adjusted Hazard Ratio): 2.3, 95% CI: 1.2, 4.5), Shock (AHR: 7.9, 95% CI: 3.7, 16.7), no intake of antibiotics (AHR: 2.3 95% CI: 1.2, 4.4), IV-Fluid (AHR: 3.2, 95% CI: 1.7, 5.8), no intake of F75 (AHR: 6.6,95% CI: 2.9, 14.7) and no intake of F100 (AHR: 3, 95% CI: 1.6, 5.4) were independent predictors of mortality. Conclusion: The survival status of under-five children with SAM was lower than the national standard protocol. Altered general conditions such as shock, anemia, not adhering to medical and nutritional therapies were identified as predictors of mortality among SAM children. Health education on early medical seeking behavior and adherence on the routine regimens may improve this gap in child survival. PMID- 30275953 TI - Effective combined therapy with ramucirumab for advanced pulmonary pleomorphic carcinoma. AB - Pulmonary pleomorphic carcinoma (PPC) is a rare disease with a poor prognosis. Most patients with PPC are refractory to chemotherapy, whereas good responses to platinum-based chemotherapy in combination with the anti-angiogenesis agent bevacizumab have been reported. An 82-year-old man was diagnosed with PPC with a clinical stage of T3N0M0, coincident with primary lung adenocarcinoma in an early stage. We chose single-agent chemotherapy with docetaxel as an initial treatment, but both the primary adenocarcinoma and two PPC lesions in the right lung were enlarged after one treatment cycle. We subsequently started treatment with ramucirumab and docetaxel, and thereafter, the disease showed a good partial response. Here, we report the first case of advanced PPC that was effectively treated with chemotherapy and the anti-VEGFR-2 antibody ramucirumab. These observations suggest a potential therapeutic strategy for patients with PPC. PMID- 30275952 TI - SRSF2 mutations in myelodysplasia/myeloproliferative neoplasms. AB - Recurrent gene mutations have been described with varying frequencies in myelodysplasia (MDS) /myeloproliferative neoplasm (MPN) overlap syndromes (MMOS). Recent work has placed significant focus on understanding the role of gene lesions involving the spliceosomal machinery in leukemogeneis. SRSF2 is a gene encoding critical spliceosomal proteins. SRSF2 mutations appear to play an important role in pathogenesis of MMOS, particularly in chronic myelomonocytic leukemia. Inhibition of splicing may be a new therapeutic approach. E7107, a spliceosome inhibitor, has been shown to differentially inhibit splicing more in SRSF2-mutant cells leading to decreased leukemia burden in mice. H3B-8800 is a small molecule modulator of spliceosome complex and has been shown to lower leukemia burden in SRSF2-P95H mutant mice. This review focuses on the incidence of mutant SRSF2 across various MMOS as well as recent clinical development of spliceosome inhibitors. PMID- 30275954 TI - A case of lung tumorlets secondary to pulmonary hypoplasia with recurrent haemoptysis. AB - Most patients with lung tumorlets are usually asymptomatic, and most diagnoses are incidental findings during microscopic lung examinations at autopsy or after excision of a tissue lesion. A 73-year-old woman was admitted to our hospital due to recurrent haemoptysis. Chest computed tomography demonstrated right inferior lobe collapse with bronchiectasis. Bronchoscopic examination revealed the right inferior lobar bronchus to be filled with blood clots. Haemoptysis persisted even after two arterial embolization trials and occlusion with endobronchial Watanabe spigot. Therefore, right lower lobectomy was performed, and multiple tumorlets on lobar hypoplasia were observed on histopathological examination of the excised specimen. We believe that the haemoptysis in our patient was possibly caused by the lung tumorlets secondary to lobar hypoplasia. PMID- 30275955 TI - Habitat suitability does not capture the essence of animal-defined corridors. AB - Background: Increases in landscape connectivity can improve a species' ability to cope with habitat fragmentation and degradation. Wildlife corridors increase landscape connectivity and it is therefore important to identify and maintain them. Currently, corridors are mostly identified using methods that rely on generic habitat suitability measures. One important and widely held assumption is that corridors represent swaths of suitable habitat connecting larger patches of suitable habitat in an otherwise unsuitable environment. Using high-resolution GPS data of four large carnivore species, we identified corridors based on animal movement behavior within each individual's home range and quantified the spatial overlap of these corridors. We thus tested whether corridors were in fact spatial bottle necks in habitat suitability surrounded by unsuitable habitat, and if they could be characterized by their coarse-scale environmental composition. Results: We found that most individuals used corridors within their home ranges and that several corridors were used simultaneously by individuals of the same species, but also by individuals of different species. When we compared the predicted habitat suitability of corridors and their immediate surrounding area we found, however, no differences. Conclusions: We could not find a direct correspondence between corridors chosen and used by wildlife on the one hand, and a priori habitat suitability measurements on the other hand. This leads us to speculate that identifying corridors relying on typically-used habitat suitability methods alone may misplace corridors at the level of space use within an individual's home range. We suggest future studies to rely more on movement data to directly identify wildlife corridors based on the observed behavior of the animals. PMID- 30275956 TI - Premedication to reduce anxiety in patients undergoing coronary angiography and percutaneous coronary intervention. AB - Aims: In this study, we examined the effects of the routinely administration of benzodiazepines on reducing periprocedural anxiety versus no premedication. Methods: In this open label study, we enrolled 1683 patients undergoing diagnostic coronary angiograms (CAG) or percutaneous coronary interventions (PCI). Randomisation was simulated by systematically allocating patients in monthly rotational periods to lorazepam 1 mg/sl, oxazepam 10 mg/po, diazepam 5 mg/po, midazolam 7.5 mg/po or no premedication. Anxiety was measured at four different time points using the one-item Visual Analogue Scale for Anxiety (VAS score) ranging from 0 to 10. The primary outcome was the difference in anxiety reduction (DeltaVAS, preprocedure to postprocedure), between the different premedication strategies versus no premedication. Results: Anxiety reduction was larger in patients premedicated with lorazepam (DeltaVAS=-2.0, SE=1.6, P=0.007) or diazepam (DeltaVAS=-2.0, SE=1.5, p=0.003) compared with patients without any premedication (DeltaVAS=-1.4, SE=1.2). The use of midazolam or oxazepam did not lead to a significant reduction in anxiety compared with patients who did not receive premedication. Additionally, a high number of patients treated with midazolam (N=39, 19.8%) developed side effects. Conclusions: In this study, the use of lorazepam or diazepam was associated with a significant, but modest anxiety reduction in patients undergoing CAG or PCI. This study does not support the standard use of oxazepam or midazolam as premedication to reduce anxiety. PMID- 30275957 TI - Guideline-defined futility or patient-reported outcomes to assess treatment success after TAVI: what to use? Results from a prospective cohort study with long-term follow-up. AB - Objective: Transcatheter aortic valve implantation (TAVI) provides a significant symptom relief and mortality reduction in most patients; however, a substantial group of patients does not experience the same beneficial results according to physician-determined outcomes. Methods: Single-centre prospective design; the population comprises all consecutive patients undergoing TAVI in 2012-2017. TAVI futility was defined as the combined endpoint of either no symptomatic improvement or mortality at 1 year. We actively gathered telephone follow-up using a predefined questionnaire. Results: Guideline defined TAVI futility was present in 212/741 patients. Multivariate regression showed lower albumin and non transfemoral approach to be predictive for futility. In addition to these, chronic obstructive pulmonary disease, lower estimated glomerular filtration rate, atrial fibrillation, low-flow-low-gradient aortic stenosis and lower Body Mass Index were predictive for 1-year mortality. Patients who showed symptomatic benefit estimated the percentage in which their symptoms were remedied higher than patients who did not (80% vs 60%, p<0.001). Guideline-defined TAVI futility occurs frequently, contrasting with patient-reported outcome measures (PROMs). The vast majority in both groups would again choose for TAVI treatment. Conclusion: Lower albumin and non-transfemoral access route were predictors for guideline-defined TAVI futility, defined as mortality within 1 year or no objective symptomatic improvement in New York Heart Association class. Futility according to this definition occurred frequently in this study, contrasting with much more positive PROMs. The majority of patients would undergo a TAVI again, underlining the patients' experienced value of TAVI and putting the definition of TAVI futility further on debate. In the near future, less-strict criteria for TAVI futility, that is, using a shorter warranted life expectancy and incorporating patients' perceived outcomes, should be used. PMID- 30275959 TI - Liver abscess caused by Gram-negative spiral bacilli. PMID- 30275958 TI - Extensively drug-resistant (XDR) Pseudomonas aeruginosa identified in Lima, Peru co-expressing a VIM-2 metallo-beta-lactamase, OXA-1 beta-lactamase and GES-1 extended-spectrum beta-lactamase. AB - Introduction: Pseudomonas aeruginosa has the ability to acquire plasmids and other mobile genetic elements that confer resistance to antibiotics. Bacterial genes encoding different beta-lactamases (bla), such as metallo-beta-lactamases (MBLs) and extended-spectrum beta-lactamases (ESBL), can confer resistance to multiple classes of beta-lactam antibiotics. Case presentation: An 83 year old female was admitted in 2012 to the Peruvian Naval Hospital, Centro Medico Naval 'Cirujano Mayor Santiago Tavara' (CEMENA), in Lima, Peru. A midstream urine sample was collected and sent to the local CEMENA laboratory for routine urine culture. P. aeruginosa was isolated and initial antibiotic susceptibility testing showed it to be sensitive to imipenem. The clinicians started a course of meropenem, but the patient did not improve. After 5 days, a second urine culture was performed and a P. aeruginosa was isolated again, but this time the strain showed resistance to imipenem. The treatment course was changed to fosfomycin and the patient improved. Phenotypic and molecular laboratory testing to characterize the antibiotic resistance were performed, demonstrating the presence of both MBL and ESBL genes. Conclusion: To our knowledge, this is the first report of a P. aeruginosa XDR clinical isolate that co-expresses an MBL (VIM-2), OXA-1 beta lactamase and the ESBL (GES-1) in Peru. It is also the first report of a VIM carbapenemase in Peru. PMID- 30275960 TI - Staphylococcus haemolyticus epididymo-orchitis and bacteraemia: a case report. AB - Introduction: Although more often recognized as a culprit in female urinary tract infection, coagulase-negative staphylococci (CoNS) can cause severe genitourinary infections in men. While positive blood cultures with CoNS are usually thought to be contaminants, in the setting of a severe genito-urinary infection they can represent true infection. Case presentation: We present the case of a 70-year-old male without a central venous catheter or urinary catheter who developed Staphylococcus haemolyticus bloodstream infection secondary to epididymo orchitis. Conclusion: This case highlights the importance of prompt recognition of serious CoNS infections, including bacteraemia, in the setting of CoNS genitourinary tract infections. PMID- 30275961 TI - Mycobacterium xenopi systemic infection in a domestic fiery-shouldered conure bird (Pyrrhura egregia). AB - Introduction: Mycobacterium xenopi is a rare opportunistic pathogen mainly causing infections in immunocompromised human patients or those with underlying chronic structural lung disease. Cases of disease in veterinary medicine remain scarce. Few animal species, including birds, are suspected of being vectors of the disease and there has not yet been a report of clinical disease in birds. We report the first case, to our knowledge, of systemic infection in a domestic bird. Case presentation: A female fiery-shouldered conure was submitted after death for necropsy following episodes of heavy breathing. The necropsy revealed multiple granulomatous lesions within the liver, air sacs and kidneys. Ziehl Neelsen stains demonstrated the presence of numerous intralesional acid-fast bacilli. PCR assays and culture confirmed the presence of M. xenopi. Conclusion: Through this case we hope to describe the characteristics of M. xenopi disease in birds and the possible close relationship between animal and human infections. PMID- 30275962 TI - Isolated appendiceal endometriosis resulting in intussusception. AB - An inverted (intussuscepted) appendix is a rare finding, often mistaken for a polyp as it presents with vague symptoms. This can result in misdiagnosis and inappropriate management. Diagnosis is usually made through surgery. Rarely, endometriosis has been found as the cause of the intussusception. A 42-year-old woman presented with frequent loose stools over 2 years, an elevated calprotectin over 400 MUg/g faeces (normal <110) and a serum C-reactive protein of 40 mg/l (normal <5 mg/l). Endoscopy showed an inverted appendix. Histopathology results showed inflammation and ulceration. Laparoscopic appendicectomy was performed successfully, and endometriosis was found on the inverted appendix. This is the first case reported of an inverted appendix containing endometriosis, in which the intussusception of the appendix has been diagnosed on endoscopy. This case highlights how endometriosis can involve just the appendix, without any involvement of reproductive organs. We suggest considering inverted appendix as a differential diagnosis when investigating caecal lesions. PMID- 30275963 TI - A community-driven reconstruction of the Aspergillus niger metabolic network. AB - Background: Aspergillus niger is an important fungus used in industrial applications for enzyme and acid production. To enable rational metabolic engineering of the species, available information can be collected and integrated in a genome-scale model to devise strategies for improving its performance as a host organism. Results: In this paper, we update an existing model of A. niger metabolism to include the information collected from 876 publications, thereby expanding the coverage of the model by 940 reactions, 777 metabolites and 454 genes. In the presented consensus genome-scale model of A. niger iJB1325 , we integrated experimental data from publications and patents, as well as our own experiments, into a consistent network. This information has been included in a standardized way, allowing for automated testing and continuous improvements in the future. This repository of experimental data allowed the definition of 471 individual test cases, of which the model complies with 373 of them. We further re-analyzed existing transcriptomics and quantitative physiology data to gain new insights on metabolism. Additionally, the model contains 3482 checks on the model structure, thereby representing the best validated genome-scale model on A. niger developed until now. Strain-specific model versions for strains ATCC 1015 and CBS 513.88 have been created containing all data used for model building, thereby allowing users to adopt the models and check the updated version against the experimental data. The resulting model is compliant with the SBML standard and therefore enables users to easily simulate it using their preferred software solution. Conclusion: Experimental data on most organisms are scattered across hundreds of publications and several repositories.To allow for a systems level understanding of metabolism, the data must be integrated in a consistent knowledge network. The A. niger iJB1325 model presented here integrates the available data into a highly curated genome-scale model to facilitate the simulation of flux distributions, as well as the interpretation of other genome scale data by providing the metabolic context. PMID- 30275964 TI - Appearance alteration of fruits and vegetables to increase their appeal to and consumption by school-age children: A pilot study. AB - Picky eating with regard to fruit and vegetables is common among children. This study investigated the effectiveness of enhancing the visual appeal of fruit and vegetables to increase children's liking and consumption of fruit and vegetables. A pre-post experimental design was used, and the control and experimental groups were repeatedly exposed to the original food and transformed food, respectively, over 6 weeks. Significant differences in the consumption of pumpkin, sweet potato, spinach, carrot and aubergine were observed between the groups, demonstrating that the appearance appeal of fruit and vegetables improves the willingness of children to try disliked fruit and vegetables and increases their vegetable consumption. PMID- 30275965 TI - What causes fibromyalgia? An online survey of patient perspectives. AB - Fibromyalgia is a severe chronic pain condition that affects every aspect of life. Causes of the condition remain unclear, and quantitative research cannot account for patients' personal illness narratives and perceptions. This online survey gathered qualitative accounts of the perceived causes of their condition from 596 people with fibromyalgia, which were analyzed thematically. Themes were "Bodily assault, ill-health, and change"; "Emotional trauma and distress"; "Stress and vulnerability"; and "Explaining and authenticating fibromyalgia." Discussion focuses on the complexity of causation, the importance of understanding and having symptoms validated, and the potential for benefiting from patient expertise in building better practitioner-client relationships. PMID- 30275966 TI - Feasibility and acceptability of technology-based caregiver engagement strategies delivered in a summertime childhood obesity prevention intervention: results from an internal pilot of the Camp NERF (Nutrition, Education, Recreation, and Fitness) study. AB - Background: The most efficacious childhood obesity prevention interventions have involved caregivers directly or indirectly. Due to the high reliance on technology, research examining technological intervention approaches is warranted, particularly during the summer when parents may be more difficult to engage and the risk for excess weight gain among children is high. Methods: The feasibility and acceptability of a multi-component childhood obesity prevention intervention incorporating a caregiver component utilizing technology-based approaches-texting and social media-was explored. This was an internal pilot of the Camp Nutrition Education Recreation and Fitness (NERF) study, a group RCT for school-age children coupled to the USDA Summer Food Service Program. Feasibility and acceptability of the technology caregiver engagement component were assessed via process outcomes (participation rates) and in-depth interviews. Results: Participants (n = 37) were 91.9% female, 91.8% Black, 58.7% low-income, and 75.0% overweight/obese. Participation rates in texting and social media were 62.2% and < 3%, respectively. Themes emerged from the in-depth interviews were texting provides connection; desire more involvement with program; fear social media privacy intrusion. Conclusions: Results will be used to inform changes to technology-based caregiver engagement strategies to be tested in future interventions. Trial registration: Clinical Trials, NCT02908230/09-19-2016. Registered 20 September 2016. PMID- 30275967 TI - New opportunities for nanoparticles in cancer immunotherapy. AB - Background: Recently, cancer immunotherapy has become standard for cancer treatment. Immunotherapy not only treats primary tumors, but also prevents metastasis and recurrence, representing a major advantage over conventional cancer treatments. However, existing cancer immunotherapies have limited clinical benefits because cancer antigens are often not effectively delivered to immune cells. Furthermore, unlike lymphoma, solid tumors evade anti-cancer immunity by forming an immune-suppressive tumor microenvironment (TME). One approach for overcoming these limitations of cancer immunotherapy involves nanoparticles based on biomaterials. Main body: Here, we review in detail recent trends in the use of nanoparticles in cancer immunotherapy. First, to illustrate the unmet needs for nanoparticles in this field, we describe the mechanisms underlying cancer immunotherapy. We then explain the role of nanoparticles in the delivery of cancer antigens and adjuvants. Next, we discuss how nanoparticles can be helpful within the immune-suppressive TME. Finally, we summarize current and future uses of nanoparticles with image-guided interventional techniques in cancer immunotherapy. Conclusion: Recently developed approaches for using nanoparticles in cancer immunotherapy have enormous potential for improving cancer treatment. Cancer immunotherapy based on nanoparticles is anticipated not only to overcome the limitations of existing immunotherapy, but also to generate synergistic effects via cooperation between nanoparticles and immune cells. PMID- 30275968 TI - Clinical development of photodynamic agents and therapeutic applications. AB - Background: Photodynamic therapy (PDT) is photo-treatment of malignant or benign diseases using photosensitizing agents, light, and oxygen which generates cytotoxic reactive oxygens and induces tumour regressions. Several photodynamic treatments have been extensively studied and the photosensitizers (PS) are key to their biological efficacy, while laser and oxygen allow to appropriate and flexible delivery for treatment of diseases. Introduction: In presence of oxygen and the specific light triggering, PS is activated from its ground state into an excited singlet state, generates reactive oxygen species (ROS) and induces apoptosis of cancer tissues. Those PS can be divided by its specific efficiency of ROS generation, absorption wavelength and chemical structure. Main body: Up to dates, several PS were approved for clinical applications or under clinical trials. Photofrin(r) is the first clinically approved photosensitizer for the treatment of cancer. The second generation of PS, Porfimer sodium (Photofrin(r)), Temoporfin (Foscan(r)), Motexafin lutetium, Palladium bacteriopheophorbide, Purlytin(r), Verteporfin (Visudyne(r)), Talaporfin (Laserphyrin(r)) are clinically approved or under-clinical trials. Now, third generation of PS, which can dramatically improve cancer-targeting efficiency by chemical modification, nano-delivery system or antibody conjugation, are extensively studied for clinical development. Conclusion: Here, we discuss up-to-date information on FDA approved photodynamic agents, the clinical benefits of these agents. However, PDT is still dearth for the treatment of diseases in specifically deep tissue cancer. Next generation PS will be addressed in the future for PDT. We also provide clinical unmet need for the design of new photosensitizers. PMID- 30275970 TI - Injectable hydrogels delivering therapeutic agents for disease treatment and tissue engineering. AB - Background: Injectable hydrogels have been extensively researched for the use as scaffolds or as carriers of therapeutic agents such as drugs, cells, proteins, and bioactive molecules in the treatment of diseases and cancers and the repair and regeneration of tissues. It is because they have the injectability with minimal invasiveness and usability for irregularly shaped sites, in addition to typical advantages of conventional hydrogels such as biocompatibility, permeability to oxygen and nutrient, properties similar to the characteristics of the native extracellular matrix, and porous structure allowing therapeutic agents to be loaded. Main body: In this article, recent studies of injectable hydrogel systems applicable for therapeutic agent delivery, disease/cancer therapy, and tissue engineering have reviewed in terms of the various factors physically and chemically contributing to sol-gel transition via which gels have been formed. The various factors are as follows: several different non-covalent interactions resulting in physical crosslinking (the electrostatic interactions (e.g., the ionic and hydrogen bonds), hydrophobic interactions, pi-interactions, and van der Waals forces), in-situ chemical reactions inducing chemical crosslinking (the Diels Alder click reactions, Michael reactions, Schiff base reactions, or enzyme or photo-mediated reactions), and external stimuli (temperatures, pHs, lights, electric/magnetic fields, ultrasounds, or biomolecular species (e.g., enzyme)). Finally, their applications with accompanying therapeutic agents and notable properties used were reviewed as well. Conclusion: Injectable hydrogels, of which network morphology and properties could be tuned, have shown to control the load and release of therapeutic agents, consequently producing significant therapeutic efficacy. Accordingly, they are believed to be successful and promising biomaterials as scaffolds and carriers of therapeutic agents for disease and cancer therapy and tissue engineering. PMID- 30275971 TI - Hypoxic condition enhances chondrogenesis in synovium-derived mesenchymal stem cells. AB - Background: The chondrogenic differentiation of mesenchymal stem cells (MSCs) is regulated by many factors, including oxygen tensions, growth factors, and cytokines. Evidences have suggested that low oxygen tension seems to be an important regulatory factor in the proliferation and chondrogenic differentiation in various MSCs. Recent studies report that synovium-derived mesenchymal stem cells (SDSCs) are a potential source of stem cells for the repair of articular cartilage defects. But, the effect of low oxygen tension on the proliferation and chondrogenic differentiation in SDSCs has not characterized. In this study, we investigated the effects of hypoxia on proliferation and chondrogenesis in SDSCs. Method: SDSCs were isolated from patients with osteoarthritis at total knee replacement. To determine the effect of oxygen tension on proliferation and colony-forming characteristics of SDSCs, A colony-forming unit (CFU) assay and cell counting-based proliferation assay were performed under normoxic (21% oxygen) or hypoxic (5% oxygen). For in vitro chondrogenic differentiation, SDSCs were concentrated to form pellets and subjected to conditions appropriate for chondrogenic differentiation under normoxia and hypoxia, followed by the analysis for the expression of genes and proteins of chondrogenesis. qRT-PCR, histological assay, and glycosoaminoglycan assays were determined to assess chondrogenesis. Results: Low oxygen condition significantly increased proliferation and colony forming characteristics of SDSCs compared to that of SDSCs under normoxic culture. Similar pellet size and weight were found for chondrogensis period under hypoxia and normoxia condition. The mRNA expression of types II collagen, aggrecan, and the transcription factor SOX9 was increased under hypoxia condition. Histological sections stained with Safranin-O demonstrated that hypoxic conditions had increased proteoglycan synthesis. Immunohistochemistry for types II collagen demonstrated that hypoxic culture of SDSCs increased type II collagen expression. In addition, GAG deposition was significantly higher in hypoxia compared with normoxia at 21 days of differentiation. Conclusion: These findings show that hypoxia condition has an important role in regulating the synthesis ECM matrix by SDSCs as they undergo chondrogenesis. This has important implications for cartilage tissue engineering applications of SDSCs. PMID- 30275969 TI - Micro-CT - a digital 3D microstructural voyage into scaffolds: a systematic review of the reported methods and results. AB - Background: Cell behavior is the key to tissue regeneration. Given the fact that most of the cells used in tissue engineering are anchorage-dependent, their behavior including adhesion, growth, migration, matrix synthesis, and differentiation is related to the design of the scaffolds. Thus, characterization of the scaffolds is highly required. Micro-computed tomography (micro-CT) provides a powerful platform to analyze, visualize, and explore any portion of interest in the scaffold in a 3D fashion without cutting or destroying it with the benefit of almost no sample preparation need. Main body: This review highlights the relationship between the scaffold microstructure and cell behavior, and provides the basics of the micro-CT method. In this work, we also analyzed the original papers that were published in 2016 through a systematic search to address the need for specific improvements in the methods section of the papers including the amount of provided information from the obtained results. Conclusion: Micro-CT offers a unique microstructural analysis of biomaterials, notwithstanding the associated challenges and limitations. Future studies that will include micro-CT characterization of scaffolds should report the important details of the method, and the derived quantitative and qualitative information can be maximized. PMID- 30275972 TI - Layer-by-layer assembled polymeric thin films as prospective drug delivery carriers: design and applications. AB - Background: The main purpose of drug delivery systems is to deliver the drugs at the appropriate concentration to the precise target site. Recently, the application of a thin film in the field of drug delivery has gained increasing interest because of its ability to safely load drugs and to release the drug in a controlled manner, which improves drug efficacy. Drug loading by the thin film can be done in various ways, depending on type of the drug, the area of exposure, and the purpose of drug delivery. Main text: This review summarizes the various methods used for preparing thin films with drugs via Layer-by-layer (LbL) assembly. Furthermore, additional functionalities of thin films using surface modification in drug delivery are briefly discussed. There are three types of methods for preparing a drug-carrying multilayered film using LbL assembly. First methods include approaches for direct loading of the drug into the pre-fabricated multilayer film. Second methods are preparing thin films using drugs as building blocks. Thirdly, the drugs are incorporated in the cargo so that the cargo itself can be used as the materials of the film. Conclusion: The appropriate designs of the drug-loaded film were produced in consideration of the release amounts and site of the desired drug. Furthermore, additional surface modification using the LbL technique enabled the preparation of effective drug delivery carriers with improved targeting effect. Therefore, the multilayer thin films fabricated by the LbL technique are a promising candidate for an ideal drug delivery system and the development possibilities of this technology are infinite. PMID- 30275973 TI - Synthesis and characterization of thiolated hexanoyl glycol chitosan as a mucoadhesive thermogelling polymer. AB - Background: Mucoadhesive polymers, which may increase the contact time between the polymer and the tissue, have been widely investigated for pharmaceutical formulations. In this study, we developed a new polysaccharide-based mucoadhesive polymer with thermogelling properties. Methods: Hexanoyl glycol chitosan (HGC), a new thermogelling polymer, was synthesized by the chemical modification of glycol chitosan using hexanoic anhydride. The HGC was further modified to include thiol groups to improve the mucoadhesive property of thermogelling HGC. The degree of thiolation of the thiolated HGCs (SH-HGCs) was controlled in the range of 5-10% by adjusting the feed molar ratio. The structure of the chemically modified polymers was characterized by 1H NMR and ATR-FTIR. The sol-gel transition, mucoadhesiveness, and biocompatibility of the polymers were determined by a tube inverting method, rheological measurements, and in vitro cytotoxicity tests, respectively. Results: The aqueous solution (4 wt%) of HGC with approximately 33% substitution showed a sol-gel transition temperature of approximately 41 degrees C. SH-HGCs demonstrated lower sol-gel transition temperatures (34 +/- 1 and 31 +/ 1 degrees S) compared to that of HGC due to the introduction of thiol groups. Rheological studies of aqueous mixture solutions of SH-HGCs and mucin showed that SH-HGCs had stronger mucoadhesiveness than HGC due to the interaction between the thiol groups of SH-HGCs and mucin. Additionally, we confirmed that the thermogelling properties might improve the mucoadhesive force of polymers. Several in vitro cytotoxicity tests showed that SH-HGCs showed little toxicity at concentrations of 0.1-1.0 wt%, indicating good biocompatibility of the polymers. Conclusions: The resultant thiolated hexanoyl glycol chitosans may play a crucial role in mucoadhesive applications in biomedical areas.

PMID- 30275976 TI - The antibacterial efficacy of a foam mouthwash and its ability to remove biofilms. AB - Objectives/Aims: To evaluate the antimicrobial activity of a newly developed foam mouthwash containing a modified lactoperoxidase system in vitro. Materials and methods: Biofilms of five bacterial species were developed on hydrophobic and hydrophilic surfaces whilst salivary-based biofilm was grown on tooth enamel. Each surface was exposed to the foam mouthwash or saline in vitro. Optical density and scanning electron microscopy (SEM) was used to determine retention of the biofilm following 5 or 30 s exposure time. Results: The foam mouthwash was active against biofilms formed by S. aureus, K. rhizophila, M. thailandicus, E. coli, and C. violaceum and eliminated significant amount of biofilm from each surface; immature 4 h biofilm was less resistant than 24 h biofilm. A 30 s rinse showed best performance, with removal of up to 66% of biofilm from the hydrophilic surface. SEM imaging confirmed oral biofilm removal from the enamel surface after a 5 s rinse with the foam mouthwash. Discussion: Foam mouthwash demonstrated a significant impact on growing biofilm when compared against saline solution. Growing biofilms were more susceptible to the action of the foam mouthwash, which justifies after-meal use of the mouthwash when traditional dentifrices may not be accessible. Conclusions: Foam mouthwash can be a convenient on-the-go format of oral care products that can be used after meals or when needed to reduce the risk of biofilm-associated oral conditions. PMID- 30275974 TI - Non-insulin determinant pathways maintain glucose homeostasis upon metabolic surgery. AB - Insulin is critical for glucose homeostasis, and insulin deficiency or resistance leads to the development of diabetes. Recent evidence suggests that diabetes can be remitted independent of insulin. However, the underlying mechanism remains largely elusive. In this study, we utilized metabolic surgery as a tool to identify the non-insulin determinant mechanism. Here, we report that the most common metabolic surgery, Roux-en-Y gastric bypass (RYGB), reduced insulin production but persistently maintained euglycemia in healthy Sprague-Dawley (SD) rats and C57 mice. This reduction in insulin production was associated with RYGB mediated inhibition of pancreatic preproinsulin and polypyrimidine tract-binding protein 1. In addition, RYGB also weakened insulin sensitivity that was evaluated by hyperinsulinemic-euglycemic clamp test and downregulated signaling pathways in insulin-sensitive tissues. The mechanistic evidence suggests that RYGB predominately shifted the metabolic profile from glucose utilization to fatty acid oxidation, enhanced the energy expenditure and activated multiple metabolic pathways through reducing gut energy uptake. Importantly, the unique effect of RYGB was extended to rats with islet disruption and patients with type 2 diabetes. These results demonstrate that compulsory rearrangement of the gastrointestinal tract can initiate non-insulin determinant pathways to maintain glucose homeostasis. Based on the principle of RYGB action, the development of a noninvasive intervention of the gastrointestinal tract is a promising therapeutic route to combat disorders characterized by energy metabolism dysregulation. PMID- 30275977 TI - Identification of Burkholderia fungorum in the urine of an individual with spinal cord injury and augmentation cystoplasty using 16S sequencing: copathogen or innocent bystander? AB - Introduction: People with neuropathic bladder (NB) secondary to spinal cord injury (SCI) are at risk for multiple genitourinary complications, the most frequent of which is urinary tract infection (UTI). Despite the high frequency with which UTI occurs, our understanding of the role of urinary microbes in health and disease is limited. In this paper, we present the first prospective case study integrating symptom reporting, urinalysis, urine cultivation, and 16S ribosomal ribonucleic acid (rRNA) sequencing of the urine microbiome. Case presentation: A 55-year-old male with NB secondary to SCI contributed 12 urine samples over an 8-month period during asymptomatic, symptomatic, and postantibiotic periods. All bacteria identified on culture were present on 16S rRNA sequencing, however, 16S rRNA sequencing revealed the presence of bacteria not isolated on culture. In particular, Burkholderia fungorum was present in three samples during both asymptomatic and symptomatic periods. White blood cells of >=5-10/high power field and leukocyte esterase >=2 on urinalysis was associated with the presence of symptoms. Discussion: In this patient, there was a predominance of pathogenic bacteria and a lack of putative probiotic bacteria during both symptomatic and asymptomatic states. Urinalysis-defined inflammatory markers were present to a greater extent during symptomatic periods compared to the asymptomatic state, which may underscore a role for urinalysis or other inflammatory markers in differentiating asymptomatic bacteriuria from UTI in patients with NB. The finding of potentially pathogenic bacteria identified by sequencing but not cultivation, suggests a need for greater understanding of the relationships amongst bacterial species in the bacteriuric neuropathic bladder. PMID- 30275978 TI - Rapid incremental closed traction reduction of cervical facet fracture dislocation: the Stoke Mandeville experience. AB - Study design: Retrospective case series study. Objective: To determine the success rate and neurological outcomes of rapid incremental closed traction reduction (RICTR) of cervical dislocations with spinal cord compression in the National Spinal Injuries Centre (NSIC), between June 2006 and December 2011. Setting: Tertiary spinal injuries centre, Stoke Mandeville Hospital, UK. Methods: A list of cervical trauma patients who were admitted to NSIC between January 2006 and December 2011 was retrieved from the hospital's electronic records, consultant and admission logbooks. Patients, admitted within 7 days of cervical facet dislocation and spinal cord injury (SCI), were included. Retrospective data collection and analysis was done using a data collection form and an Excel spreadsheet. Results: Seventeen patients have met the eligibility criteria of the study. One patient was excluded because he only had nerve root symptoms. The procedure was successful in 44% of the cases. Eighty-six percent of patients in the successful RICTR group improved in their discharge motor index score (MIS), whereas 43% improved in their post-reduction MIS. Overall, 81% of the cohort had improvements in their discharge MIS. Conclusion: Our RICTR success rate was low compared to the reported average success rate in the literature, likely due to delays in admission. Neurological outcomes were favourable in the majority of patients at discharge. In our opinion, early admission and RICTR attempts could have improved the results and therefore we would recommend that RICTR procedures are done for suitable patients in the Emergency Departments of Major Trauma Centres (MTC). PMID- 30275979 TI - Spinal subdural and epidural hematomas after vertebroplasty for compression fracture: a case report. AB - Introduction: Vertebroplasty (VP) is a well-known and effective therapeutic method for relieving the pain and improving the quality of life of patients with vertebral compression fractures. Major complications of VP are infrequent, occurring in no more than 1% of such procedures, whereas spinal subdural and epidural hematomas are extremely rare complications. Case Presentation: We present a unique case of a spinal subdural hematoma (sSDH) (from T4 to T12) occurring immediately after VP to treat a traumatic vertebral compression fracture, followed by a spinal epidural hematoma (SEH) (from T3 to T12) after the decompressive laminectomy, occurring in a 64-year-old patient. After removing of the big spinal epidural hematoma, the patient's symptoms improved progressively and she recovered after 2 months. Discussion: This is a rare case of sSDH and SEH occurring continuously after VP. The pathogenesis may be that the puncture damaged the abnormal blood vessel of spinal dura mater. A small-probability event is not an impossible event. We hope to bring more attention to the rare complications of VP by sharing this unusual case. PMID- 30275980 TI - Evaluation of a ketogenic diet for improvement of neurological recovery in individuals with acute spinal cord injury: a pilot, randomized safety and feasibility trial. AB - Study design: Longitudinal, randomized study. Objectives: (1) Test the safety and feasibility of a ketogenic diet (KD) intervention in the acute stages of spinal cord injury (SCI), (2) assess the effects of a KD on neurological recovery, and (3) identify potential serum biomarkers associated with KD-induced changes in neurological recovery. Setting: Acute care and rehabilitation facility. Methods: The KD is a high-fat, low-carbohydrate diet that includes ~70-80% total energy as fat. Seven participants with acute complete and incomplete SCI (AIS A-D) were randomly assigned to KD (n = 4) or standard diet (SD, n = 3). Neurological examinations, resting energy expenditure analysis, and collection of blood for evaluation of circulating ketone levels were performed within 72 h of injury and before discharge. Untargeted metabolomics analysis was performed on serum samples to identify potential serum biomarkers that may explain differential responses between groups. Results: Our pilot findings primarily demonstrated that KD is safe and feasible to be administered in acute SCI. Furthermore, upper extremity motor scores were higher (p < 0.05) in the KD vs. SD group and an anti inflammatory lysophospholipid, lysoPC 16:0, was present at higher levels, and an inflammatory blood protein, fibrinogen, was present at lower levels in the KD serum samples vs. SD serum samples. Conclusion: Taken together, these preliminary results suggest that a KD may have anti-inflammatory effects that may promote neuroprotection, resulting in improved neurological recovery in SCI. Future studies with larger sample size are warranted for demonstrating efficacy of KD for improving neurological recovery. PMID- 30275981 TI - The role of miR-106p-5p in cervical cancer: from expression to molecular mechanism. AB - This study aims to investigate the role of miR-106b-5p in cervical cancer by performing a comprehensive analysis on its expression and identifying its putative molecular targets and pathways based on The Cancer Genome Atlas (TCGA) dataset, Gene Expression Omnibus (GEO) dataset, and literature review. Significant upregulation of miR-106b-5p in cervical cancer is confirmed by meta analysis with the data from TCGA, GEO, and literature. Moreover, the expression of miR-106b-5p is significantly correlated with the number of metastatic lymph nodes. Our bioinformatics analyses show that miR-106b could promote cervical cancer progression by modulating the expression of GSK3B, VEGFA, and PTK2 genes. Importantly, these three genes play a crucial role in PI3K-Akt signaling, focal adhesion, and cancer. Both the expression of miR-106b-5p and key genes are upregulated in cervical cancer. Several explanations could be implemented for this upregulation. However, the specific mechanism needs to be investigated further. PMID- 30275983 TI - Reported use of reporting guidelines among JNCI: Journal of the National Cancer Institute authors, editorial outcomes, and reviewer ratings related to adherence to guidelines and clarity of presentation. AB - Background: Associations were examined between author-reported uses of reporting guidelines to prepare JNCI: Journal of the National Cancer Institute (JNCI) submissions, editorial decisions, and reviewer ratings for adherence to reporting guidelines and clarity of presentation. Methods: At submission, authors were asked if they used reporting guidelines to prepare their manuscript and, if so, which one(s). Reviewers rated adherence to reporting guidelines and clarity of presentation. Data were gathered using a customized Editorial Manager Enterprise Analytics Report for submissions with first or final decisions that were submitted between November 1, 2015, and April 30, 2017. Manuscript types that would benefit from the use of reporting guidelines were included. All reviews were included in the analyses. Numerical values were given to each answer (yes, 1; no, 0) or reviewer rating (not applicable, 0; fair, 1; poor, 2; good, 3; very good, 4; and outstanding, 5), and scores were compared using two-sided t tests. Results: Of 2209 submissions included in the analysis, 1144 (51.8%) indicated that at least one reporting guideline was used. The STROBE guidelines were the most common (n = 531, 24.0%). Of the 2068 (93.6%) submissions that were rejected, 1105 (50.1%) indicated using reporting guidelines and 963 (43.6%) did not (mean [SD] scores of rejected vs not rejected, 0.53 [0.50] vs 0.49 [0.50], P = .47). Of the 1033 ratings for adherence to reporting guidelines, mean (SD) scores for not rejected vs rejected submissions were 3.2 (1.61) vs 2.9 (1.57) (P = .005), and mean (SD) scores for reporting guidelines use vs no use were 3.1 (1.48) vs 2.9 (1.70) (P = .01). Of the 1036 ratings for clarity of presentation, mean (SD) scores for not rejected vs rejected submissions were 3.6 (1.00) vs 3.1 (1.08) (P < .001), whereas mean (SD) scores for reporting guidelines use vs no use were 3.3 (1.04) vs 3.3 (1.10) (P = .64). Conclusions: Among these JNCI submissions, reporting the use of reporting guidelines was not associated with editorial decisions or with reviewer ratings for clarity of presentation. Reviewer ratings for adherence to guidelines and clarity of presentation were associated with editorial decisions after peer review, and ratings for adherence to guidelines were associated with reported use of reporting guidelines. PMID- 30275985 TI - Erratum: Author Correction: Selection and evaluation of an efficient method for the recovery of viral nucleic acids from complex biologicals. AB - [This corrects the article DOI: 10.1038/s41541-018-0067-3.]. PMID- 30275982 TI - Misoprostol regulates Bnip3 repression and alternative splicing to control cellular calcium homeostasis during hypoxic stress. AB - The cellular response to hypoxia involves the activation of a conserved pathway for gene expression regulated by the transcription factor complex called hypoxia inducible factor (HIF). This pathway has been implicated in both the adaptive response to hypoxia and in several hypoxic-ischemic-related pathologies. Perinatal hypoxic injury, often associated with prematurity, leads to multi-organ dysfunction resulting in significant morbidity and mortality. Using a rodent model of neonatal hypoxia and several representative cell lines, we observed HIF1alpha activation and down-stream induction of the cell death gene Bnip3 in brain, large intestine, and heart which was mitigated by administration of the prostaglandin E1 analog misoprostol. Mechanistically, we determined that misoprostol inhibits full-length Bnip3 (Bnip3-FL) expression through PKA-mediated NF-kappaB (P65) nuclear retention, and the induction of pro-survival splice variants. We observed that the dominant small pro-survival variant of Bnip3 in mouse cells lacks the third exon (Bnip3DeltaExon3), whereas human cells produce a pro-survival BNIP3 variant lacking exon 2 (BNIP3DeltaExon2). In addition, these small Bnip3 splice variants prevent mitochondrial dysfunction, permeability transition, and necrosis triggered by Bnip3-FL by blocking calcium transfer from the sarco/endoplasmic reticulum to the mitochondria. Furthermore, misoprostol and Bnip3DeltaExon3 promote nuclear calcium accumulation, resulting in HDAC5 nuclear export, NFAT activation, and adaptive changes in cell morphology and gene expression. Collectively, our data suggests that misoprostol can mitigate the potential damaging effects of hypoxia on multiple cell types by activating adaptive cell survival pathways through Bnip3 repression and alternative splicing. PMID- 30275986 TI - Stepwise development of a simulation environment for operating room teams: the example of vertebroplasty. AB - Background: Despite the growing importance of medical simulation in education, there is limited guidance available on how to develop medical simulation environments, particularly with regard to technical and non-technical skills as well as to multidisciplinary operating room (OR) team training. We introduce a cognitive task analysis (CTA) approach consisting of interviews, structured observations, and expert consensus to systematically elicit information for medical simulator development. Specifically, our objective was to introduce a guideline for development and application of a modified CTA to obtain task demands of surgical procedures for all three OR professions with comprehensive definitions of OR teams' technical and non-technical skills. Methods: To demonstrate our methodological approach, we applied it in vertebroplasty, a minimally invasive spine procedure. We used a CTA consisting of document reviews, in situ OR observations, expert interviews, and an expert consensus panel. Interviews included five surgeons, four OR nurses, and four anesthetists. Ten procedures were observed. Data collection was carried out in five OR theaters in Germany. Results: After compiling data from interviews and observations, we identified 6 procedural steps with 21 sub-steps for surgeons, 20 sub-steps for nurses, and 22 sub-steps for anesthetists. Additionally, we obtained information on 16 predefined categories of intra-operative skills and requirements for all three OR professions. Finally, simulation requirements for intra-operative demands were derived and specified in the expert panel. Conclusions: Our CTA approach is a feasible and effective way to elicit information on intra-operative demands and to define requirements of medical team simulation. Our approach contributes as a guideline to future endeavors developing simulation training of technical and non-technical skills for multidisciplinary OR teams. PMID- 30275984 TI - A new era in cytomegalovirus vaccinology: considerations for rational design of next-generation vaccines to prevent congenital cytomegalovirus infection. AB - Human cytomegalovirus (HCMV), a member of the beta-herpesvirus family, is the most common cause of congenital infection worldwide as well as an important cause of morbidity in transplant recipients and immunosuppressed individuals. An estimated 1 in 150 infants are infected with HCMV at birth, which can result in lifelong, debilitating neurologic sequelae including microcephaly, sensorineural hearing loss, and cognitive impairment. Natural maternal immunity to HCMV decreases the frequency of reinfection and reduces risk of congenital transmission but does not completely protect against neonatal disease. Thus, a vaccine to reduce the incidence and severity of infant infection is a public health priority. A variety of candidate HCMV vaccine approaches have been tried previously, including live-attenuated viruses, glycoprotein subunit formulations, viral vectors, and single/bivalent DNA plasmids, but all have failed to reach target endpoints in clinical trials. Nevertheless, there is a great deal to be learned from the successes and failures of the HCMV vaccine field (both congenital and transplant-associated), as well as from vaccine development efforts for other herpesvirus pathogens including herpes simplex virus 1 and 2, varicella zoster virus, and Epstein-Barr virus. Here, we review those successes and failures, evaluating recent cutting-edge discoveries that have shaped the HCMV vaccine field and identifying topics of critical importance for future investigation. These considerations will inform rational design and evaluation of next-generation vaccines to prevent HCMV-associated congenital infection and disease.

PMID- 30275989 TI - Transforming Retinal Photographs to Entropy Images in Deep Learning to Improve Automated Detection for Diabetic Retinopathy. AB - Entropy images, representing the complexity of original fundus photographs, may strengthen the contrast between diabetic retinopathy (DR) lesions and unaffected areas. The aim of this study is to compare the detection performance for severe DR between original fundus photographs and entropy images by deep learning. A sample of 21,123 interpretable fundus photographs obtained from a publicly available data set was expanded to 33,000 images by rotating and flipping. All photographs were transformed into entropy images using block size 9 and downsized to a standard resolution of 100 * 100 pixels. The stages of DR are classified into 5 grades based on the International Clinical Diabetic Retinopathy Disease Severity Scale: Grade 0 (no DR), Grade 1 (mild nonproliferative DR), Grade 2 (moderate nonproliferative DR), Grade 3 (severe nonproliferative DR), and Grade 4 (proliferative DR). Of these 33,000 photographs, 30,000 images were randomly selected as the training set, and the remaining 3,000 images were used as the testing set. Both the original fundus photographs and the entropy images were used as the inputs of convolutional neural network (CNN), and the results of detecting referable DR (Grades 2-4) as the outputs from the two data sets were compared. The detection accuracy, sensitivity, and specificity of using the original fundus photographs data set were 81.80%, 68.36%, 89.87%, respectively, for the entropy images data set, and the figures significantly increased to 86.10%, 73.24%, and 93.81%, respectively (all p values <0.001). The entropy image quantifies the amount of information in the fundus photograph and efficiently accelerates the generating of feature maps in the CNN. The research results draw the conclusion that transformed entropy imaging of fundus photographs can increase the machinery detection accuracy, sensitivity, and specificity of referable DR for the deep learning-based system. PMID- 30275987 TI - The intracellular signalosome of PD-L1 in cancer cells. AB - Programmed cell death-1 ligand-1 (PD-L1) overexpression in cancer cells accelerates tumor progression. PD-L1 possesses two main pro-oncogenic functions. First, PD-L1 is a strong immunosuppressive molecule that inactivates tumor specific T cells by binding to the inhibitory receptor PD-1. Second, PD-L1 function relies on the delivery of intrinsic intracellular signals that enhance cancer cell survival, regulate stress responses and confer resistance toward pro apoptotic stimuli, such as interferons. Here, we review the current knowledge on intracellular signal transduction pathways regulated by PD-L1, describe its associated signalosome and discuss potential combinations of targeted therapies against the signalosome with PD-L1/PD-1 blockade therapies. PMID- 30275988 TI - Morphological Characterization of Emerging Cercariae among Lymnaeid Snails from Barangay Cawongan, Padre Garcia, Batangas, Philippines. AB - Background and Objectives: Lymnaeid snails are the known intermediate hosts of the liver fluke Fasciola spp. and therefore play an important role in the parasite's life cycle. The study is conducted to determine specificity of snail host-parasite interaction and to determine the snail-trematode infection rate by cercarial emergence, characterizing the emerging larvae using standardized key. Materials and Methods: A total of 750 snails were collected from a rice field in Barangay Cawongan, Padre Garcia, Batangas, from November 2016 to March 2017 (n=150/month). Preliminary snail identification was based on morphological features of the shell. Each snail was acclimatized for 24 hours in a 50-ml capacity container before being exposed to strong artificial light. The 150 snails collected per month were grouped into 5 batches (n=30/batch) with each batch receiving different number of light exposures. Emerging cercariae were described and characterized using photo-referencing and standardized keys. All statistical tests were performed at p<0.05 level of significance using SPSS ver. 20. Results: The total cercarial shedding rate of the snails studied, as a measure of the infected snails, was found to be 35.6% and was positively associated with the length of the snail shell [OR = 1.809; 95% CI: 1.471-2.225; p<0.001], but not with the weight [OR = 0.003; 95% CI: 0.00-0.275; p=0.012] and width of the shell [OR = 0.937; 95% CI: 0.672-1.305]. The rates varied from 29.3% to 38.0% based on the frequency of 6-hour light exposure. Appearance of encysted forms increased with increasing number of light exposures [OR = 10.27, 95% CI: 3.04-34.76, p<0.001]. Three distinct cercariae were identified, namely, echinostome, longifurcate-pharyngeate distome cercariae (Strigea cercariae), and the virgulate xiphidiocercaria, with 26.4%, 2.27%, and 0.67% infection monitored by cercarial emergence, respectively. Conclusion: Local lymnaeid snails were infected with a single type of trematode larvae and coinfection with multiple larvae was rare but was encountered. PMID- 30275992 TI - Chronic, Recreational Chloroform-Induced Liver Injury. AB - Historically used as an anesthetic, chloroform is a halogenated hydrocarbon that is associated with central nervous system depression, arrhythmias, and hepatotoxicity. It is no longer used clinically, but accidental and intentional poisonings still occur. We report a case of chronic chloroform abuse leading to severe hepatotoxicity in a 26-year-old male graduate student. The patient presented to the emergency department with a three-day history of abdominal pain, dehydration, and scleral icterus. He drank several beers the night before the onset of symptoms, but denied taking acetaminophen, ibuprofen, or other drugs. An extensive work-up revealed an aspartate aminotransferase (AST) of 13,527 U/L and alanine aminotransferase (ALT) of 8,745 U/L, but the cause of his liver injury could not be determined. It was not until many months later that the patient admitted to inhaling chloroform in the weeks leading up to his illness. PMID- 30275991 TI - Retrospective Multivariate Analysis of Data from Children with Suspected Appendicitis: A New Tool for Diagnosis. AB - Background: Decision-making for management may sometimes be difficult in acute appendicitis (AA). Various diagnostic scoring systems exist, but their sensitivity and specificity rates are far from ideal. In this study, the determination of the predictors and the effect of radiological data and developing a new scoring system were aimed. Methods: Medical records of patients who were hospitalized for AA between February 2012 and October 2016 were retrospectively reviewed. All data were compared between patients with and without appendicitis. The multivariate analysis was performed to define significant variables and to examine the sensitivity and specificity of each group of predictors including radiological data. A new scoring system (NSS) was formed and was compared with two existing scoring systems: pediatric appendicitis score (PAS) and Alvarado scoring system (ASS) by using reclassification method. Results: Negative appendectomy rate was 11.3%. Statistical analysis identified 21 independently significant variables. The heel drop test had the highest odds ratio. Sensitivity and specificity rates of clinical predictors were 84.6% and 94.8%, respectively. Radiological predictors increased the sensitivity rate to 86.9%. Sensitivity and specificity rates for PAS, ASS, and NSS were 86.8% and 83.9%, 84.7% and 81.6%, and 96.8% and 95.6%, respectively. The "re-assessed negative appendectomy rate" was 6.2% and false positive results were remarkably more common in patients with duration of symptoms less than 24 hours. Conclusion: Radiological data improves the accuracy of diagnosis. Containing detailed clinical and radiological data, NSS performs superiorly to PAS and ASS, regarding sensitivity and specificity without any age limitation. The efficiency of NSS may be enhanced by determining different predictors for different phases of the inflammatory process. PMID- 30275994 TI - Talus Bipartitus: A Rare Anatomical Variant Presenting as an Entrapment Neuropathy of the Tibial Nerve within the Tarsal Tunnel. AB - Tarsal tunnel syndrome is an entrapment neuropathy of the tibial nerve within the tarsal tunnel that lies beneath the retinaculum on the medial side of the ankle. It is often underdiagnosed. Talus bipartitus is a rare anatomical variant; only a few cases have been described in medical literature. We report a case of a 36 year-old female with tarsal tunnel syndrome secondary to a talus bipartitus undergoing surgical treatment with good clinical outcome. To our knowledge, talus bipartitus presenting as tarsal tunnel syndrome has no previous reports. Image studies and physical examination are crucial to reach precise diagnosis. PMID- 30275993 TI - Iatrogenic Teratoma Rupture during TVOR Complicated with Peritonitis, Pleuritis, and Septic Shock. AB - Objective: To obtain a better understanding of the clinical course and the subsequent complications of teratoma rupture. Case: We report a rare case of chemical peritonitis and pleuritis caused by teratoma rupture during ultrasonographically guided transvaginal oocyte retrieval (TVOR). The patient initially presented with nonspecific and digestive symptoms after TVOR, but the condition deteriorated rapidly after three weeks with peritonitis and septic shock. Thus, exploratory laparoscopy was performed with the findings of a ruptured teratoma at left adnexa, severe adhesions, and purulent fluid in her peritoneal cavity. Bilateral pleuritis was also noted after the operation, which was suspected to be caused by chemical irritation of the spilled contents of the teratoma. The patient's condition improved after surgical treatment and was discharged 28 days after admission. Conclusion: Our case showed that the timing of peritoneal irritation caused by teratoma rupture converting to severe chemical peritonitis was approximately 3 weeks. Physicians should avoid cyst puncture during TVOR and closely observe or even perform surgical treatment when iatrogenic teratoma ruptures are suspected. PMID- 30275995 TI - Primary Hyperparathyroidism due to Parathyroid Adenoma Originated from Supernumerary Gland. AB - Introduction: The variability of the location of the parathyroid glands is directly related to the events that occur during embryonic development. The impact that an individual submits more than four parathyroid glands is close to 13%. However the presentation of a parathyroid adenoma in a supernumerary gland is an uncommon event. Case report: A 30-year-old man diagnosed with primary hyperparathyroidism with matching findings on ultrasonography and scintigraphy for parathyroid adenoma localization lower left regarding the thyroid gland. A cervicotomy explorer showed four orthotopic parathyroid glands. The biopsy of the inferior left gland was normal. No signs of adenoma were seen in the biopsy. Following mobilization of the ipsilateral thyroid lobe, fifth parathyroid gland was found increased significantly in size than proceeded to remove, confirming the diagnosis of adenoma. After the excision, the levels of serum calcium and parathyroid hormone were normalized. Conclusions: The presentation of a parathyroid adenoma in a supernumerary gland is a challenge for the surgeon. The high sensitivity having different imaging techniques has been a key to locate preoperatively the pathological parathyroid gland. Analytical or clinical persistence of primary hyperparathyroidism after parathyroid surgery can occur if the location of the adenoma is a supernumerary or ectopic gland location.

AB - An 8-year-old neutered male miniature Poodle presented for evaluation of a suspected T3-L3 lesion with cervical component following vehicular trauma. Magnetic resonance imaging and computed tomography revealed a T2-T3 luxation with right displacement of T3. A T2 caudal endplate fracture was present as well as multifocal noncompressive bulges of cervical intervertebral discs. Conservative management failed and ventral stabilization of C7-T4 was performed via a median sternotomy. Paired String-of-Pearls plates were placed on the ventral aspect of vertebrae. Eight weeks postoperatively, the dog was ambulatory with moderate pelvic limb paraparesis. A luxation of T2-T3 is uncommon in small animals and surgical stabilization is poorly described in literature. This case report demonstrates the use of a ventral approach to cranial thoracic vertebral stabilization with a successful outcome. PMID- 30275997 TI - New RP-HPLC Method Development and Validation for Dorzolamide in Ophthalmic Dosage Form. AB - A reversed phase liquid chromatographic method with UV detection at 254 nm for dorzolamide assay in ophthalmic solutions was developed and validated. Chromatographic separation was achieved on a Zorbax SB C18 (250 mm * 4.6 mm, 5 um) column kept at 30 degrees C with an isocratic mixture of mobile phase (phosphate buffer, pH 2.5, and acetonitrile, 90 : 10 v/v) at a flow rate of 0.8 mL/min. The method was validated for its specificity, linearity, accuracy, precision, limit of detection, limit of quantification, and robustness based on ICH guidelines. The validation studies revealed satisfactory results. The proposed method has been applied for the quantification of dorzolamide in commercial samples. The developed method is fast, simple, specific, accurate, and sensitive, hence can be applied for routine quality control analysis of dorzolamide in pharmaceutical dosage form. PMID- 30275998 TI - Surgical Treatment of Gastroesophageal Junction Cancer. AB - Although the incidence of gastroesophageal junction (GEJ) adenocarcinoma has been increasing worldwide, no standardized surgical strategy for its treatment has been established. This study aimed to provide an update on the surgical treatment of GEJ adenocarcinoma by reviewing previous reports and propose recommended surgical approaches. The Siewert classification is widely used for determining which surgical procedure is used, because previous studies have shown that the pattern of lymph node (LN) metastasis depends on tumor location. In terms of surgical approaches for GEJ adenocarcinoma, a consensus was reached based on two randomized controlled trials. Siewert types I and III are treated as esophageal cancer and gastric cancer, respectively. Although no consensus has been reached regarding the treatment of Siewert type II, several retrospective studies suggested that the optimal treatment strategy includes paraaortic LN dissection. Against this background, a Japanese nationwide prospective trial is being conducted to determine the proportion of LN metastasis in GEJ cancers and to identify the optimal extent of LN dissection in each type. PMID- 30275999 TI - Preoperative Nodal 18F-FDG Avidity Rather than Primary Tumor Avidity Determines the Prognosis of Patients with Advanced Gastric Cancer. AB - Purpose: This study investigated whether the metabolic avidity of primary tumors and/or metastatic lymph nodes (LNs) measured by 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) was related to survival after surgery in patients with advanced gastric cancer (AGC). Materials and Methods: One hundred sixty-eight patients with AGC who underwent preoperative 18F FDG PET/CT and curative resection were included. The 18F-FDG avidity of the primary gastric tumor and LNs was determined quantitatively and qualitatively. The diagnostic performance of 18F-FDG PET/CT was calculated, and the prognostic significance of 18F-FDG avidity for recurrence-free survival (RFS) and overall survival (OS) was assessed. Results: In all, 51 (30.4%) patients experienced recurrence, and 32 (19.0%) died during follow-up (median follow-up duration, 35 months; range, 3-81 months); 119 (70.8%) and 33 (19.6%) patients showed 18F-FDG avid primary tumors and LNs, respectively. 18F-FDG PET/CT showed high sensitivity (73.8%) for the detection of advanced pathologic T (pT >=3) stage and high specificity (92.2%) for the detection of advanced pN (>=2) stage. 18F-FDG avidity of LNs was significantly associated with RFS (P=0.012), whereas that of primary tumors did not show significance (P=0.532). Univariate and multivariate analyses revealed that 18F-FDG avidity of LNs was an independent prognostic factor for RFS (hazard ratio=2.068; P=0.029). Conclusions: 18F-FDG avidity of LNs is an independent prognostic factor for predicting RFS. Preoperative 18F-FDG PET/CT can be used to determine the risk and prognosis of patients with AGC after curative resection. PMID- 30276000 TI - Enhanced Recovery after Surgery for Gastric Cancer Patients Improves Clinical Outcomes at a US Cancer Center. AB - Purpose: Enhanced recovery after surgery (ERAS) protocols for gastric cancer patients have shown improved outcomes in Asia. However, data on gastric cancer ERAS (GC-ERAS) programs in the United States are sparse. The purpose of this study was to compare perioperative outcomes before and after implementation of an GC-ERAS protocol at a National Comprehensive Cancer Center in the United States. Materials and Methods: We reviewed medical records of patients surgically treated for gastric cancer with curative intent from January 2012 to October 2016 and compared the GC-ERAS group (November 1, 2015-October 1, 2016) with the historical control (HC) group (January 1, 2012-October 31, 2015). Propensity score matching was used to adjust for age, sex, number of comorbidities, body mass index, stage of disease, and distal versus total gastrectomy. Results: Of a total of 95 identified patients, matching analysis resulted in 20 and 40 patients in the GC ERAS and HC groups, respectively. Lower rates of nasogastric tube (35% vs. 100%, P<0.001) and intraabdominal drain placement (25% vs. 85%, P<0.001), faster advancement of diet (P<0.001), and shorter length of hospital stay (5.5 vs. 7.8 days, P=0.01) were observed in the GC-ERAS group than in the HC group. The GC ERAS group showed a trend toward increased use of minimally invasive surgery (P=0.06). There were similar complication and 30-day readmission rates between the two groups (P=0.57 and P=0.66, respectively). Conclusions: The implementation of a GC-ERAS protocol significantly improved perioperative outcomes in a western cancer center. This finding warrants further prospective investigation. PMID- 30276001 TI - Sarcopenia and Post-Operative Morbidity and Mortality in Patients with Gastric Cancer. AB - Purpose: Surgical resection for gastric adenocarcinoma is associated with significant post-operative morbidity and mortality. The aim of this study was to assess the prognostic significance of sarcopenia in patients undergoing resection for gastric adenocarcinoma with respect to post-operative morbidity and survival. Materials and Methods: A retrospective analysis was conducted on a cohort of consecutive patients who underwent surgical resection for gastric adenocarcinoma between 2008 and 2014. Patient demographics, radiological parameters, and pathological data were collected. OsiriX software (Pixmeo) was used to measure skeletal muscle area, which was normalized for height to calculate skeletal muscle index. Results: A total of 56 patients (41 male, 15 female; mean age, 68.4 +/- 11.9 years) met the inclusion criteria. Of these, 36% (20 of 56) of the patients were sarcopenic pre-operatively. Both sarcopenic and non-sarcopenic patient groups were equally matched with the exception of weight and body mass index (P=0.036 and 0.001, respectively). Sarcopenia was associated with a decreased overall survival (log-rank P=0.003) and was an adverse prognostic predictor of overall survival in multivariate analysis (hazard ratio, 10.915; P=0.001). Sarcopenia was a predictor of serious in-hospital complications in multivariate analysis (odds ratio, 3.508; P=0.042). Conclusions: In patients undergoing curative resection for gastric cancer, there was a statistically significant association between sarcopenia and both decreased overall survival and serious post-operative complications. The measurement and reporting of skeletal muscle index on pre-operative computed tomography should be considered. PMID- 30276002 TI - Impact of Various Types of Comorbidities on the Outcomes of Laparoscopic Total Gastrectomy in Patients with Gastric Carcinoma. AB - Purpose: With increasing life expectancy, the presence of comorbidities has become a major concern in elderly patients who require surgery. However, little is known about the impact of different comorbidities on the outcomes of laparoscopic total gastrectomy (LTG). In this study, we investigated the impact of comorbidities on postoperative complications in patients undergoing LTG for gastric carcinoma. Materials and Methods: We retrospectively reviewed the cases of 303 consecutive patients who underwent LTG for gastric carcinoma between 2005 and 2016. The associations between each comorbidity and postoperative complications were assessed using univariate and multivariate analyses. Results: A total of 189 patients (62.4%) had one or more comorbidities. Hypertension was the most common comorbidity (37.0%), followed by diabetes mellitus (17.8%), chronic viral hepatitis (2.6%), liver cirrhosis (2.6%), and pulmonary (27.1%), ischemic heart (3.3%), and cerebrovascular diseases (2.3%). The overall postoperative morbidity and mortality rates were 20.1% and 1.0%, respectively. Patients with pulmonary disease significantly showed higher complication rates than those without comorbidities (32.9% vs. 14.9%, respectively, P=0.003); patient with other comorbidities showed no significant difference in the incidence of LTG-related complications. During univariate and multivariate analyses, pulmonary disease was found to be an independent predictive factor for postoperative complications (odds ratio, 2.14; 95% confidence interval, 1.03 4.64), along with old age and intraoperative bleeding. Conclusions: Among the various comorbidities investigated, patients with pulmonary disease had a significantly higher risk of postoperative complications after LTG. Proper perioperative care for optimizing pulmonary function may be required for patients with pulmonary disease. PMID- 30276003 TI - Who Can Perform Adjuvant Chemotherapy Treatment for Gastric Cancer? A Multicenter Retrospective Overview of the Current Status in Korea. AB - Purpose: To investigate the current status of adjuvant chemotherapy (AC) regimens in Korea and the difference in efficacy of AC administered by surgical and medical oncologists in patients with stage II or III gastric cancers. Materials and Methods: We performed a retrospective observational study among 1,049 patients who underwent curative resection and received AC for stage II and III gastric cancers between February 2012 and December 2013 at 29 tertiary referral university hospitals in Korea. To minimize the influence of potential confounders on selection bias, propensity score matching (PSM) was used based on binary logistic regression analysis. The 3-year disease-free survival (DFS) rates were compared between patients who received AC administered by medical oncologists or surgical oncologists. Results: Between February 2012 and December 2013 in Korea, the most commonly prescribed AC by medical oncologists was tegafur/gimeracil/oteracil (S-1, 47.72%), followed by capecitabine with oxaliplatin (XELOX, 16.33%). After performing PSM, surgical oncologists (82.74%) completed AC as planned more often than medical oncologists (75.9%), with statistical significance (P=0.036). No difference in the 3-year DFS rates of stage II (P=0.567) or stage III (P=0.545) gastric cancer was found between the medical and surgical oncologist groups. Conclusions: S-1 monotherapy and XELOX are a main stay of AC, regardless of whether the prescribing physician is a medical or surgical oncologist. The better compliance with AC by surgical oncologists is a valid reason to advocate that surgical oncologists perform the treatment of AC for stage II or III gastric cancers. PMID- 30276004 TI - The Impact of Preoperative Low Body Mass Index on Postoperative Complications and Long-term Survival Outcomes in Gastric Cancer Patients. AB - Purpose: The aim of this study was to investigate the impact of preoperative low body mass index (BMI) on both the short- and long-term outcomes in patients with gastric cancer. Materials and Methods: A total of 510 patients with gastric cancer were divided into the following 3 groups: low BMI group (<=18.5 kg/m2, n=51), normal BMI group (18.6-24.9 kg/m2, n=308), and high BMI group (>=25.0 kg/m2, n=151). Results: There were significantly more stage III/IV patients in the low BMI group than in the other groups (P=0.001). Severe postoperative complications were more frequent (P=0.010) and the survival was worse (P<0.001) in the low BMI group. The subgroup analysis indicated that survival was worse in the low BMI group of the stage I/II subgroup (P=0.008). The severe postoperative complication rate was higher in the low BMI group of the stage III/IV subgroup (P=0.001), although the recurrence rate and survival did not differ in the stage III/IV subgroup among all the BMI groups. Low BMI was an independent poor prognostic factor in the stage I/II subgroup (disease-free survival: hazard ratio [HR], 13.521; 95% confidence interval [CI], 1.186-154.197; P=0.036 and overall survival: HR, 5.130; 95% CI, 1.644-16.010; P=0.005), whereas low BMI was an independent risk factor for severe postoperative complications in the stage III/IV subgroup (HR, 17.158; 95% CI, 1.383-212.940; P=0.027). Conclusions: Preoperative low BMI in patients with gastric cancer adversely affects survival among those with stage I/II disease and increases the severe postoperative complication rate among those with stage III/IV disease. PMID- 30276005 TI - Safety of Laparoscopic Radical Gastrectomy in Gastric Cancer Patients with End Stage Renal Disease. AB - Purpose: The surgical outcomes of end-stage renal disease (ESRD) patients undergoing radical gastrectomy for gastric cancer were inferior compared with those of non-ESRD patients. This study aimed to evaluate the short- and long-term surgical outcomes of ESRD patients undergoing laparoscopic gastrectomy (LG) and open gastrectomy (OG) for gastric cancer. Materials and Methods: Between 2004 and 2014, 38 patients (OG: 21 patients, LG: 17 patients) with ESRD underwent gastrectomy for gastric cancer. Comparisons were made based on the clinicopathological characteristics, surgical outcomes, and long-term survival rates. Results: No significant differences were noted in the clinicopathological characteristics of either group. LG patients had lower estimated blood loss volumes than OG patients (LG vs. OG: 94 vs. 275 mL, P=0.005). The operation time and postoperative hospital stay were similar in both the groups. The postoperative morbidity for LG and OG patients was 41.1% and 33.3%, respectively (P=0.873). No significant difference was observed in the long-term overall survival rates between the 2 groups (5-year overall survival, LG vs. OG: 82.4% vs. 64.7%, P=0.947). Conclusions: In ESRD patients, LG yielded non-inferior short and long-term surgical outcomes compared to OG. Laparoscopic procedures might be safely adopted for ESRD patients who can benefit from the advantages of minimally invasive surgery. PMID- 30276006 TI - Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy as Treatment Options for Peritoneal Metastasis of Advanced Gastric Cancer. AB - Purpose: This study aimed to examine the outcomes of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with peritoneal metastasis (PM) of advanced gastric cancer (AGC). Materials and Methods: Between May 2015 and June 2017, 38 CRS and HIPEC procedures were performed in patients with PM of AGC at the Dankook University Hospital. We prospectively collected and analyzed data regarding PM grade, morbidity and mortality rates, and short-term follow-up results (median, 13.5 months). Results: The mean peritoneal cancer index was 15 (range, 0-39). Complete cytoreduction was achieved in 21 patients (55.2%), whereas complications occurred in 16 (42.1%) and 2 (5.7%) patients died. The overall median patient survival time was 19 months. The patients who underwent complete cytoreduction had a median survival time of 26 months, which was significantly longer than the median survival time of 16 months in the patients who did not undergo complete cytoreduction (P=0.006). Conclusions: CRS with HIPEC may have a beneficial effect in patients with PM of AGC. However, the rates of complications and mortality associated with this combined therapeutic approach are high. Therefore, this treatment should be performed only in selected patients by surgeons experienced in the field of gastric cancer with PM. PMID- 30276007 TI - Long-term Survival after Repeated Local Therapy and Salvage Chemotherapy for Recurrent Metastases from Gastric Cancer: a Case Report and Literature Review. AB - We report a rare case of long-term survival in a patient who received local therapy and salvage chemotherapy for recurrent metastases, along with a literature review. A 65-year-old male patient underwent subtotal gastrectomy for advanced gastric adenocarcinoma. Six months after gastrectomy, 2 metastatic intra abdominal lymph node enlargements were detected, which were treated with radiotherapy. At 55 months after gastrectomy, an abdominal wall mass was detected, which was treated by surgical resection. The patient received 5 fluorouracil/leucovorin/irinotecan chemotherapy for 27 months before and after radiotherapy and docetaxel chemotherapy for 6 months after surgical resection of the abdominal wall metastasis. At the last visit, 7.8 years since the initial resection of the primary gastric cancer and 6.2 years since detection of the first metastases, the patient was disease-free and required no further chemotherapy. This case suggests that repeated local therapy offers potential for long-term survival in a carefully selected subset of patients with recurrent metastases. PMID- 30276009 TI - ERRATUM. PMID- 30276011 TI - IS PRE-PERFORMANCE MASSAGE EFFECTIVE TO IMPROVE MAXIMAL MUSCLE STRENGTH AND FUNCTIONAL PERFORMANCE? A SYSTEMATIC REVIEW. AB - Background: Although pre-performance massage is frequently used in sports settings, the evidence regarding its effects on muscle strength and functional performance is equivocal.Purpose: The purpose of this systematic review was to synthesize the findings of randomized controlled trials (RCTs) investigating the effects of pre-performance massage on strength and functional performance.Study Design: Systematic review with qualitative analysis. Methods: Eight electronic databases were searched from inception until June 2017. Methodological quality of included studies were assessed using Physiotherapy Evidence Database scale. Data was synthesized qualitatively. Results: Nine crossover RCTs with varied methodological qualities met inclusion criteria. Six out of nine studies had low quality, while two were of moderate-quality and one was high-quality. Following the descriptive analysis using within-group effect sizes of interventions used in included studies, no evidence was found to support the use of any kind of massage interventions (passive manual massage or self-massage) to enhance maximal strength, sprint or jump performances of young healthy subjects. In fact, there appears to be limited evidence which implies the negative effects of passive manual massage. In particular, longer-duration (> 9 minutes) of massage interventions tended to result in negative effects on lower-limb maximal strength, sprint performance and jump height. Conclusion: In conclusion, the use of longer-duration pre-performance massage cannot be recommended for enhancing young athletes' strength and performance in sprint and vertical jump. More high quality RCTs are necessary to examine overall effects of pre-performance massage on athletes' performance. Level of Evidence: 1a. PMID- 30276010 TI - ACCURACY OF THE LEVER SIGN TO DIAGNOSE ANTERIOR CRUCIATE LIGAMENT TEAR: A SYSTEMATIC REVIEW WITH META-ANALYSIS. AB - Background: The Lever sign has gained recent notoriety for its purported anterior cruciate ligament (ACL) diagnostics and simplicity of performance. Purpose: The purpose of this systematic review with meta-analysis is to summarize the diagnostic accuracy of the Lever sign for use during assessment of the knee for an ACL tear in subjects with suspected acute and chronic knee injury. Study Design: Systematic review with meta-analysis. Methods: A computer-assisted literature search of MEDLINE, CINAHL, and EMBASE databases using keywords related to diagnostic accuracy of the knee joint. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used for the search and reporting phases of the study. Quality assessment of bias and applicability was conducted using the Quality of Diagnostic Accuracy Studies (QUADAS). Mixed effects models were used to summarize accuracy. Results: Eight articles, with only two demonstrating high quality, were included. Six of the articles were included in a meta-analysis. Diagnostic values, utilizing arthroscopy as a gold standard, were: pooled SN 0.55 (95% CI 0.22 to 0.84), pooled SP 0.89 (95% CI 0.44 to 0.99), positive likelihood ratio (+LR) 9.2 (95% CI 0.70 to 46.1), negative likelihood ratio (-LR) 0.58 (95% CI 0.18 to 1.28). Post-test probability with a positive finding (57% sampling prevalence) reached 92% (95% CI 83 to 97%). Post test probability with a negative finding (57% sampling prevalence) reached 43% (95% CI 39 to 47%). Conclusions: Based on limited evidence of heterogeneous methodological quality, the Lever sign can moderately change post-test probability to rule in an ACL tear. These results should be interpreted cautiously due to a limited number of studies, with small sample sizes and study quality affecting test accuracy. Future investigation should be expanded to include additional high-quality studies examining diverse clinical contexts, as they become available, to enable a more comprehensive clinical examination of this test.

AB - Herein, we describe the development of a synthetic strategy towards chiral 3 pyrrolines based on the design principle of iron(III)-catalyzed carbonyl-olefin metathesis. This approach takes advantage of commercially available amino acids as chiral pool reagents and FeCl3 as a Lewis acid catalyst. Our strategy is characterized by its operational simplicity, mild reaction conditions and functional group tolerance. Investigations show that an electron-deficient nitrogen protecting group overcomes limitations arising from competitive binding of the Lewis acid catalyst to unfavorable Lewis basic sites, which ultimately enables catalytic turnover. PMID- 30276012 TI - TEST-RETEST RELIABILITY OF THE LIMITS OF STABILITY TEST PERFORMED BY YOUNG ADULTS USING NEUROCOM(r) VSR SPORT. AB - Background: A reliable measure of dynamic postural control is needed for inclusion in the sports-related concussion assessment battery. Currently, there is not a clinical gold standard. The Limits of Stability (LOS) test has potential to be a useful tool to collect objective data on important dynamic postural stability variables. Psychometric properties of the LOS test with healthy young adults are yet to be established. Hypothesis/Purpose: The purpose of this study was to examine the intra-session and test-retest reliability for the LOS on the NeuroCom(r) VSR Sport when performed by young adults. Study Design: Reliability study. Methods: Twenty-seven healthy university students completed four trials of the LOS in each of two testing sessions one week apart. Relative reliability was measured within each session with an intraclass correlation coefficient (ICC[3,k]) for Session 1 and Session 2, respectively, on each of the five dependent variables (movement velocity [MVL], directional control [DCL], maximum excursion [MXE], endpoint excursion [EPE], and reaction time [RT]) provided by the Neurocom. Test-retest reliability was assessed using a repeated-measures analysis of variance along with an ICC (3,k) for relative reliability. An ICC value of 0.90 or higher was defined as having a high reliability, moderate reliability for ICC values between 0.80-0.89, and below 0.80 as questionable. Results: The reliability within each session for LOS composite scores for MVL, DCL, and MXE was moderate to high (ICC[3,k]=0.89-0.95). These same three variables also had high levels of test-retest reliability (ICC[3,k]=0.95-0.96). EPE and RT had moderate reliability over time (ICC[3,k]=0.88) but differences for within session reliability. Conclusions: LOS provides a reliable measure of dynamic postural control for young adults. Two trials are recommended at baseline with the first being an adaptation trial to ensure accuracy of findings. Care needs to be taken when interpreting EPE and DCL scores on post-injury tests due to a learning effect for those variables. Level of Evidence: 2c. PMID- 30276013 TI - EVALUATION OF VERTICAL AND HORIZONTAL SACCADES USING THE DEVELOPMENTAL EYE MOVEMENT TEST COMPARED TO THE KING-DEVICK TEST. AB - Background: Oculomotor function is impaired when an individual has a concussion and as such, it is important to identify tests that are able to assess oculomotor impairment. The King-Devick (K-D) test assesses horizontal saccadic eye movement and attention. The Developmental Eye Movement (DEM) test is designed to identify oculomotor dysfunction in children. It measures both horizontal and vertical saccades. The K-D test shows promise as a concussion-screening tool and part of a multifactorial assessment. The DEM has not been tested as a concussion assessment tool, but the neuroanatomical control of horizontal and vertical saccades originates from different areas of the brain, so one might expect to see differences in performance on the K-D and DEM tests when administered to concussed patients. First, it is important to determine if performance on the DEM and K-D tests, particularly with respect to the measurement of vertical and horizontal saccades, is similar in a healthy population.Hypothesis/Purpose: The primary purpose was to evaluate the relationship between horizontal and vertical saccade tests over repeated trials in normal, healthy subjects. A secondary purpose of this study was to determine the number of trials needed to reach a performance plateau for both the DEM and K-D tests.Study Design: This study used a prospective cohort research design. Methods: Forty-two healthy non-concussed participants (22 males, 20 females; mean age, 24.2 +/- 2.92 years) completed six repeated trials of both the DEM, and then six trials of the K-D test in a single testing session. Trials within each test were performed in random order and participants were offered short rest breaks as needed between test administrations. Results: Results indicated strong correlations, r=.67, or greater, between measurements of horizontal and vertical saccades. Performance plateaued on the K-D at trial three and on the DEM at trial two for both horizontal and vertical saccades. Conclusion: It appears that the DEM and K-D tests measure similar constructs in healthy individuals and that no additional information is provided by assessment of vertical saccades. Additional studies are required to investigate the usefulness of the DEM in concussed individuals. Level of Evidence: 3: Laboratory study with repeated measures. PMID- 30276014 TI - THE RELATIONSHIP BETWEEN TRUNK ROTATION, UPPER QUARTER DYNAMIC STABILITY, AND THE KERLAN-JOBE ORTHOPAEDIC CLINIC OVERHEAD ATHLETE SHOULDER AND ELBOW SCORE IN DIVISION I COLLEGIATE PITCHERS. AB - Hypothesis/Purpose: The purpose of this study was to assess relationships between active trunk rotation range of motion (TROM), upper quarter dynamic stability, and composite and individual item KJOC scores in collegiate baseball pitchers. A secondary purpose was to determine whether differences exist between baseball pitchers with and without an injury history in terms of their performance on TROM, upper quarter dynamic stability, and composite and individual KJOC scores. It was hypothesized that increased TROM and upper quarter dynamic stability are associated with better (higher) KJOC scores and pitchers with an injury history would exhibit lower KJOC scores compared to uninjured pitchers. Study Design: Cross-sectional Cohort Study. Methods: Thirty-six college pitchers were assessed for TROM, performance on the Upper Quarter Y-Balance Test (YBT-UQ) and they also completed the KJOC. Subjects were grouped based on previous injury history: injured, required surgery, (IS, n=9), injured, no surgery, (INS, n=6), and uninjured (UI, n=21). Pearson's Correlations were used to assess relationships between clinical measurements and the KJOC. One-way ANOVAs were used to assess differences in TROM, YBT-UQ, and KJOC scores between groups (P<0.05). Results: No significant relationships were detected between TROM measures and KJOC composite scores (throwing arm: r = .239, p = 0.16; non-throwing arm: r=.291, p = 0.09). A moderate relationship was found between the YBT-UQ and the KJOC scores (throwing arm: r = .413, p = 0.01; non-throwing arm: r=.380, p = 0.02). The mean KJOC scores for item 1 (warm-up limitations) were significantly different between all three groups (IS: 6.7, INS: 9.7, UI: 9.1; p = 0.015). Mean scores on item 5 (strain on relationships with coaches) and item 8 (limitations in competition endurance) were significantly different between the IS and UI groups (Item 5 = IS: 7.8, UI: 9.5, p = 0.02; Item 8=IS: 6.4, UI: 8.8, p = 0.04). Conclusion: A positive moderate association was found between upper quarter dynamic stability as measured by the YBT-UQ and the KJOC. Pitchers with no surgical history had better KJOC scores for warm up time, competitive endurance, and impact on team relationships. Level of Evidence: 3. PMID- 30276015 TI - THE IMPACT OF WARM-UP ON YOUTH GOLFER CLUBHEAD SPEED AND SELF-REPORTED SHOT QUALITY. AB - Background/Purpose: Physical preparation in golf is now considered a key component of the game. With players becoming more athletic, warm-up has become an important area in a player's preparation for practice and competition. Much of the research to date has focused on the adult golfer, showing potential for improvements in clubhead speed, driving distance and shot quality, as well as reductions in injury risk. However, there is currently no work specifically investigating the impacts of warm-up in youth golf. The aim of this study was to examine the impact of a club only warm-up and a dynamic exercise routine followed by a club warm-up on club head speed and self-reported shot quality. Methods: Using a counterbalanced repeated measures design, eight male and 13 female youth golfers completed a control (no warm-up), club only warm-up and an exercise based dynamic warm-up followed by club warm-up on three non-consecutive days. In each session, players were required to hit 10 maximal effort shots with a driver and clubhead speed (CHS) was recorded using a launch monitor alongside self-reported shot quality scores. Results: Statistically significant improvements in clubhead speed and self-reported shot quality were seen in the dynamic warm-up combined with club warm-up. No significant differences were seen in the club-warm up only or control groups for either clubhead speed or self-reported shot quality. Conclusion: A combined dynamic physical warm-up and club warm-up improves clubhead speed and self-reported shot quality in youth golfers. However, a club warm-up alone does not seem to be sufficient in eliciting these same improvements. Level of Evidence: 3. PMID- 30276016 TI - FOUR WEEKS OF ROLLER MASSAGE TRAINING DID NOT IMPACT RANGE OF MOTION, PAIN PRESSURE THRESHOLD, VOLUNTARY CONTRACTILE PROPERTIES OR JUMP PERFORMANCE. AB - Background: Roller massagers are popular devices that are used to improve range of motion (ROM), enhance recovery from muscle soreness, and reduce pain under acute conditions. However, the effects of roller massage training and training frequency are unknown. Purpose: The objective was to compare two different roller massage training frequencies on muscle performance. Study Design: Randomized controlled intervention study. Methods: Twenty-three recreationally active university students were randomly allocated to three groups: control (n=8;), rolling three (3/W; n=8;) and six (6/W; n=7) times per week for four weeks. The roller massage training consisted of unilateral, dominant limb, quadriceps and hamstrings rolling (4 sets x 30 seconds). Both legs of participants were tested pre- and post-training for active and passive hamstrings and quadriceps range of motion (ROM), electromyography (EMG) activity during a lunge movement, unilateral countermovement jumps (CMJ), as well as quadriceps and hamstrings maximum voluntary isometric contraction (MVIC) forces and electromechanical delay. Finally, they were tested for pain pressure threshold at middle and distal segments of their quadriceps and hamstrings. Results: There were no significant training interactions for any measure with the exception that 3/W group exhibited 6.2% (p=0.03; Effect Size: 0.31) higher CMJ height from pre- (38.6 +/- 7.1 cm) to post-testing (40.9 +/- 8.1 cm) for the non-dominant limb. Conclusions: Whereas the literature has demonstrated acute responses to roller massage, the results of the present study demonstrate no consistent significant training-induced changes. The absence of change may highlight a lack of muscle and myofascial morphological or semi-permanent neurophysiological changes with rolling. Levels of Evidence: 2c. PMID- 30276018 TI - VALIDITY AND RELIABILITY OF THE FITBIT FLEXTM AND ACTIGRAPH GT3X+ AT JOGGING AND RUNNING SPEEDS. AB - Background: Monitoring levels of physical activity, as an outcome or in guiding rehabilitation, is challenging for clinicians. Personal activity monitors are increasing in popularity and provide potential to enhance rehabilitation protocols. However, research to support the validity and reliability of these devices at jogging and running speeds is limited. Purpose: The purpose of this study was to evaluate the validity of the Fitbit FlexTM and ActiGraph GT3X + for measuring step count at jogging and running speeds. A secondary purpose was to examine inter-device reliability of the Fitbit FlexTM. Study Design: Cross sectional study. Methods: Thirty healthy participants aged between 19 and 50 years, completed a treadmill protocol at jogging and running speeds (8 km/h to 16 km/h). Treadmill speed was progressively increased by intervals of 2 km/h. Each interval was four minutes in duration with a two minute rest period between stages. Participants were encouraged to continue through the graded exercise test until they reached the maximum running speed that they felt they could maintain for four minutes. Step count data was collected for Fitbit FlexTM devices and the ActiGraph GT3X+. Video analysis of step count was used as the criterion measure. Results: At speeds of 8 to 14 km/h Mean Absolute Percentage Errors were <=1% for the Fitbit FlexTM and the ActiGraph GT3X + when compared to step count via video analysis. Standard Error of Measurement between the three Fitbit FlexTM devices was <= 7 steps for speeds of 8 to 14 km/h and varied between 9 to 19 steps at 16 km/h. Fitbit FlexTM devices showed good to excellent between device reliability at speeds of 8 to14 km/h (ICC 0.723 to 0.999; p <= 0.001). Greater variability was evident with the low participant numbers at 16 km/h (ICC 0.527 to 0.896; p >= 0.02). Conclusion: Both the Fitbit FlexTM and the ActiGraph GT3X + provide a valid account of steps taken at jogging and running speeds up to 14 km/hr, attainable by non-elite runners on a treadmill. Fitbit FlexTM devices provide equivalent step count output to each other, enabling comparison between devices during treadmill jogging and running. Level of evidence: 2b. PMID- 30276017 TI - ACUTE EFFECTS OF TWO HIP FLEXOR STRETCHING TECHNIQUES ON KNEE JOINT POSITION SENSE AND BALANCE. AB - Background: Tightness of hip flexor muscles has been recognized as a risk factor for various musculoskeletal injuries in the lower extremities. Purpose: The purpose of this study was to examine the acute effects of two hip flexor stretching techniques (dynamic and hold-relax proprioceptive neuromuscular facilitation, HR-PNF) on hip extension (ROM), knee joint position sense (JPS) and balance in healthy college age students who exhibit tightness in hip flexor muscles. Study Design: Pretest-posttest randomized experimental groups. Methods: Thirty-six healthy college age students (mean = 22.37 years) with tight hip flexors participated in this study. Hip extension ROM, knee joint position sense and dynamic balance were tested pre- and post-stretching using a digital inclinometer, an iPod touch and the Y-Balance test, respectively. Subjects were randomly divided into dynamic and HR-PNF stretching groups. Three-way mixed analysis of variance was utilized to explore if an interaction existed between the groups in tested variables. Results: There was a significant effect of time on hip extension ROM in both groups (p < 0.001). There was also a significant effect of stretch type on hip extension ROM (p = 0.004) favoring hold-relax over dynamic stretching group. There was a non-significant effect of time on mean knee joint position replication error in both groups. There was a significant main effect of time on the Y-Balance test's mean distance of reach to posteromedial and posterolateral directions (p < 0.001). There was also a significant main effect of directions of reach on distances achieved (p < 0.001) favoring posterolateral over posteromedial, and the latter over anterior direction. Conclusions: The results of this study demonstrated the effectiveness of both HR PNF and dynamic stretching techniques which resulted in a significant acute improvement in hip extension ROM and dynamic balance measures, with HR-PNF being more effective than dynamic stretch. However, there were no significant improvements in knee joint position replication over time in either stretching group. Level of Evidence: 2b. PMID- 30276019 TI - COMPARISON OF BILATERAL AND UNILATERAL SQUAT EXERCISES ON BARBELL KINEMATICS AND MUSCLE ACTIVATION. AB - Purpose/Background: Bilateral squats are commonly used in lower body strength training programs, while unilateral squats are mainly used as additional or rehabilitative exercises. Little has been reported regarding the kinetics, kinematics and muscle activation in unilateral squats in comparison to bilateral squats. Therefore, the purpose of this study was to compare muscle activity, kinetics, and barbell kinematics between unilateral and bilateral squats with the same external load per leg in experienced resistance-trained participants. Methods: Fourteen resistance-trained males (age 23 +/- 4years, body mass 80.5 +/- 8.5kg and height 1.81 +/- 0.06m) participated. Barbell kinematics and surface electromyography (EMG) activity of eleven muscles were measured during the descending and ascending phase of each repetition of the squat exercises. Results: Total lifting time was longer and average and peak velocity were lower for the bilateral squat (p<0.001). Furthermore, higher muscle activity was found in the three quadriceps muscles, biceps femoris (ascending phase) and the erector spinae (ascending phase) in the bilateral squat, while greater activation for the semitendinosis (descending phase) (p=0.003) was observed for the unilateral squat with foot forwards. In the ascending phase, the prime movers showed increased muscle activity with repetition from repetition 1 to 4 (p<=0.034). Conclusions: Unilateral squats with the same external load per leg produced greater peak vertical ground reaction forces than bilateral squats, as well as higher barbell velocity, which is associated with strength development and rate of force development, respectively. The authors suggest using unilateral rather than bilateral squats for people with low back pain and those enrolled in rehabilitation programs after ACL ruptures, as unilateral squats are performed with small loads (28 vs. 135 kg) but achieve similar magnitude of muscle activity in the hamstring, calf, hip and abdominal muscles and create less load on the spine. Level of Evidence: 1b. PMID- 30276020 TI - ISOKINETIC MUSCLE PERFORMANCE AFTER ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION: A CASE-CONTROL STUDY. AB - Background: and Purpose: Knee muscle strength deficits have been reported in individuals who have undergone anterior cruciate ligament reconstruction (ACLR). Isokinetic testing is a valid way to assess muscle strength. Some isokinetic variables, including the range of motion in the phases to attain a specific velocity, load range (sustained specific velocity), time to achieve deceleration, and qualitative analysis of the torque-angle velocity relationship, may contribute to understanding recovery of these individuals after surgery. Thus, the purpose of this study was to compare the load range (LR), time to attain velocity (TTAV), deceleration time (DT) phases, total range of motion (ROM), peak torque/body mass (PT/BM), angle of peak torque (AngPT) during LR and torque-angle velocity relationships (TAV3D) between post ACLR and matched control subjects.Study design: Case-control. Methods: Seven men who underwent ACLR and seven matched controls were evaluated from four to six months after surgery. Testing was performed on a Biodex System 4 isokinetic dynamometer in concentric mode at 60, 120 and 300 degrees /s, for knee flexion and extension. Results: Statistically significant differences were seen for extension ROM at 60 degrees /s where ROM was greater in the control group. PT/BM for extensors was also significantly greater in controls by 20 % compared to ACLR at 60 and 120 degrees /s. PT/BM for flexors was significantly greater for controls at 60 degrees /s (~15 %). TAV3D showed differences in torque and, specifically, the control group sustained knee flexion torque for a greater range of motion when compared to the ACLR group. Conclusion: The ACL group presented with lower ROM and PT/BM, therefore exhibiting worse muscle performance in comparison to the control group.Level of Evidence: 3. PMID- 30276021 TI - ACUTE EFFECT OF LOW-INTENSITY ECCENTRIC EXERCISE ON ANGLE OF PEAK TORQUE IN SUBJECTS WITH DECREASED HAMSTRING FLEXIBILITY. AB - Background: Decreased hamstring flexibility and the angle of peak torque (APT) occurring at a shorter muscle length are considered risk factors for hamstring strain injury. Subjects with decreased hamstring flexibility have an APT that occurs at a shorter muscle length; hence, the susceptibility to hamstring strain injury could be associated with the APT occurring at a shorter muscle length. Low intensity eccentric exercise (ECC-Ex) may reduce hamstring strain injury risk in the subjects with decreased hamstring flexibility by allowing the APT to occur a longer muscle length. However, the acute effect of low-intensity ECC-Ex on the subjects with decreased hamstring flexibility has not been established. Hypothesis/Purpose: The purpose of this study was to investigate the acute effect of low-intensity ECC-Ex on the peak torque, APT, and hip flexion angle in the subjects with decreased hamstring flexibility. The authors hypothesized that low intensity ECC-Ex would shift the APT, allowing it to occur at a longer muscle length with a minimum decrease of peak torque and hip flexion angle in the subjects with decreased hamstring flexibility. Study design: Case-control study. Methods: Twelve male college students were categorized into normal group [n = 6 (12 legs)] and decreased hamstring flexibility group [n = 6 (12 legs)] based on the median value of the baseline hip flexion angle (i.e., 80.8 degrees ) measured by passive straight leg raise test. Peak torque and APT during maximal voluntary eccentric knee flexion (via isokinetic dynamometer) and hip flexion angle were evaluated before and after the low-intensity ECC-Ex in both groups. Results: Low-intensity ECC-Ex shifted the APT, causing it to occur at a longer muscle length in the decreased hamstring flexibility group. Low-intensity ECC-Ex increased the hip flexion angle and did not change the peak torque in both groups. Conclusion: The results of the present study demonstrated that low intensity ECC-Ex shifts the APT to occur at a longer muscle length and increases the hip flexion angle without a decrease in peak torque in the subjects with the decreased hamstring flexibility.

AB - Background: Muscle strength testing of an injured infraspinatus muscle (IM) is confounded by actions of synergistic muscles such as the posterior deltoid (PD). Hypothesis/Purpose: The purpose of this study was to describe a condition for testing of the IM that results in less EMG activity of the PD musculature. The researchers hypothesized that greater inhibition of the PD could be achieved through active adduction (AA), creating reciprocal inhibition of the PD. Study Design: Prospective cohort descriptive study. Methods: Thirty-four (19 females and 15 males) right-handed subjects between the ages of 22- 31 (mean 24.2 years + /- 6.2) with no previous history of shoulder surgery or pathology participated. Surface electrodes were placed over the muscle bellies of the IM and PD of the right shoulder along with a ground electrode over the C7 spinous process. EMG activity was recorded during resisted external rotation in four different testing conditions (seated active and passive adduction, and side-lying active and passive adduction). The order of test positions was randomly assigned, and each subject completed all four positions with appropriate rest. During AA conditions, subjects were asked to adduct the humerus against a sphygmomanometer (using 80% maximum force output) while maximal effort external rotation was manually resisted. Results: PD activity was significantly less during AA than with no AA (p<0.05) in both test positions. No significant difference occurred between IM EMG activity in the various test conditions. Conclusion: The results of this study suggest that clinicians can reduce activity of the PD without reducing activity of the IM by using AA of the humerus before applying manual resistance to test the IM during manual muscle testing.

PMID- 30276023 TI - A NOVEL APPROACH TO TREATMENT UTILIZING BREATHING AND A TOTAL MOTION RELEASE(r) EXERCISE PROGRAM IN A HIGH SCHOOL CHEERLEADER WITH A DIAGNOSIS OF FROZEN SHOULDER: A CASE REPORT. AB - Background and Purpose: Frozen shoulder (FS) is a condition of the shoulder that is characterized by gradual loss of passive and active range of motion of the glenohumeral joint. Current treatment recommendations remain unclear due to the elusive etiology of FS and absence of nomenclature in the literature. The purpose of this case report is to describe the effects of treatment guided by the assessment and treatment of a breathing pattern disorder (BPD) coupled with Total Motion Release(r) on a 17-year high school cheerleader with a diagnosis of frozen shoulder. Case Description: A 17-year-old female cheerleader reported left anterolateral chest pain after running during cheer practice. The subject continued to experience additional episodes of chest pain and sought out medical care at an emergency department where she was diagnosed with a FS. Clinical findings upon examination included soft tissue muscular irritability, glenohumeral internal and external rotation active range of motion (AROM) loss, and a dysfunctional breathing pattern. Intervention consisted of two types of breathing interventions and a Total Motion Release(r) (TMR) exercise program. The Numeric Rating Scale (NRS), inclinometer measurements to measure AROM, and breathing assessment outcomes were used to identify patient-reported outcomes and determine treatment effects. Outcomes: The use of the coupled treatment resulted in a resolution of the patient's primary complaint, an increase in AROM, and an improvement in breathing assessment outcomes. After the first treatment, internal rotation (IR) improved by 27 degrees exceeding a minimal detectable change (MDC) of 8 degrees , and after the second treatment, external rotation (ER) improved by 21 degrees exceeding a MDC of 9 degrees . Equally important, there were improvements in flexion (11 degrees ) and abduction (45 degrees ) exceeding the MDC of 8 degrees and 4 degrees respectively over the course of treatment. The minimal clinically important difference (MCID) on the NRS was exceeded when the patient returned to activity. Discussion: In this case report, breathing treatments, coupled with a TMR(r) exercise program, were beneficial treatments for this patient and provided a clinically meaningful resolution of her condition. Clinicians treating patients who display a similar presentation of frozen shoulder can consider this a possible treatment option. Levels of Evidence: Level 4; single case report. PMID- 30276024 TI - ROLLER MASSAGE: SURVEY OF PHYSICAL THERAPY PROFESSIONALS AND A COMMENTARY ON CLINICAL STANDARDS- PART II. AB - Background: Roller massage (RM) has become a popular intervention prescribed by physical therapy (PT) professionals. While this popularity has stimulated an increase in research and product development, the trends in the use of RM among PT professionals remain undocumented. It is unknown how professionals are using RM and integrating the research into their clinical practice. Purpose: To survey and document responses in the knowledge, clinical application methods, and use of RM devices among PT professionals in the United States. Design: Cross-sectional survey study. Methods: A 20-question online survey related to personal and professional demographics, beliefs about RM, preferred RM devices, RM exercise prescription, and client education was emailed to PT members of the Orthopedic and Sports Physical Therapy Sections. Results: A total of 685 sports and orthopedic PT professionals completed the survey. Most professionals surveyed believe that RM decreases pain (80%), increases mobility (68%), and increases range of motion (ROM) (40%). Fifty-one percent believed moderate density rollers have the greatest effect. Eighty percent of professionals use a foam roller in their practice and 51% recommend to clients. A high proportion of professionals prescribe RM for injury treatment (82%) and for pre and post-exercise interventions (55%). Most professionals recommend rolling daily for 30 seconds to two minutes (55%), per muscle group (64%), at a self-paced cadence (47%). A high proportion of professionals use patient reported outcomes (80%), followed by joint ROM (59%), and movement-based testing (42%) to measure effects of RM. Eighty-seven percent of professionals use live instruction to educate clients and 91% believe there is a gap in the research. Conclusion: The results of this survey should be considered descriptive and a starting point for future research to establish a consensus on optimal RM programming, devices, and application parameters for different musculoskeletal conditions. The observed responses provide some insight into how PT professionals are using RM in their practice and highlight the existing gap between the research and professional practice. Further research is needed to explore the responses documented in this study. Level of Evidence: 3.

We implemented a costing and quality improvement (QI) curriculum to Obstetrics and Gynaecology trainees using "Time-Driven Activity-Based Costing (TDABC)," and assessed its educational impact. The curriculum included didactic and practical portions. Pre and post-knowledge surveys were obtained from 24 residents on self-perceived knowledge of key QI principles. Self-perceived knowledge, before and after the curriculum, was scored on a Likert scale from 0 to 5 points (0 is the least knowledge and 5 is the most knowledge). The mean scores reported an increase in knowledge of clinical guideline development (pre = 1.19 vs. post = 3.07, p = 0.0052); confidence in participating in QI work (pre = 1.75 vs. post = 3.42 points, p < 0.0001); and knowledge in communicating QI principles (pre = 1.89, post = 3.17, p < 0.0003). Our educational programme uses the TDABC method and the residents' clinical experience effectively to teach residents cost-conscious care.

AB - Premise of the Study: Euchresta horsfieldii (Fabaceae) is a rare and endangered medicinal plant in Indonesia with restricted distribution. Single-copy nuclear DNA (scnDNA) markers were developed for this species to facilitate further investigation of genetic diversity and population structure. Methods and Results: We performed RNA-Seq and de novo assembly of the transcriptome. Ten primer sets were developed for E. horsfieldii, all of which also amplified in E. japonica and E. tubulosa. Conclusions: These scnDNA markers will be an important resource for the study of genetic diversity and population structure of E. horsfieldii and other species in the genus Euchresta. PMID- 30276027 TI - Identification of sieve elements and companion cell protoplasts by a combination of brightfield and fluorescence microscopy. AB - Premise of the Study: Phloem-limited diseases are becoming increasingly pervasive, threatening the existence of crops worldwide. Studies of phloem diseases are complicated by the inaccessibility of the phloem tissue. Phloem cells are located deep inside the plant body, are interspersed with other cell types, are among the smallest cells in the plant kingdom, and make up a small percentage of the total cell population in a plant. These properties make phloem cells difficult to investigate. Methods: We used leaf midrib protoplasts and a combination of organelle-specific dyes including Neutral Red (acidic compartments), MitoTracker Green (mitochondria), Hoechst 3342 (nucleus), and chloroplast autofluorescence. We examined the protoplasts under light and fluorescence microscopy. Results: When observed using brightfield and fluorescence microscopy, sieve element protoplasts were distinguished by the lack of vacuole and a nucleus, and by containing various mitochondria. Companion cells showed a dense cytoplasm and various small vacuoles. They also revealed their characteristic large nucleus and abundant mitochondria. Discussion: We present evidence that a combination of organelle-specific dyes and autofluorescence allows for the identification of sieve elements and companion cell protoplasts from citrus leaf tissue. PMID- 30276028 TI - Development of microsatellite markers for the resin-yielding, non-timber forest product species Boswellia serrata (Burseraceae). AB - Premise of the Study: Boswellia serrata (Burseraceae) is an economically important aromatic, gum-resin-yielding, non-timber forest tree species. Microsatellite markers were developed for B. serrata for the first time to study genetic diversity and population structure. Methods and Results: A magnetic bead enrichment method was used to develop 16 microsatellite markers, of which 11 were polymorphic. The number of alleles per locus in the 60 individuals studied ranged from three to 10, and the levels of observed and expected heterozygosity ranged from 0.50 to 0.90 and 0.666 to 0.861, respectively. The primers successfully amplified in the congeneric species B. ovalifoliolata. Conclusions: These microsatellite markers can be used to study the genetic variation and population structure of B. serrata and to provide crucial information on population and ecological issues for management and conservation of the species. PMID- 30276029 TI - Molecular markers for Nassella trichotoma (Poaceae) to study genetic variation in New Zealand. AB - Premise of The Study: Simple sequence repeat (SSR) markers were developed for the study of genetic diversity of New Zealand Nassella trichotoma (Poaceae) and to support future studies in its native range. Methods and Results: Genomic DNA was extracted from N. trichotoma leaf material and subjected to Roche 454 sequencing. From a total of 745 putative SSRs, 48 with di- to pentanucleotide repeats were screened, 32 primer pairs were designed, and 15 polymorphic markers were optimized for multiplex PCR on 105 N. trichotoma samples from four New Zealand regions. Each locus resulted in two to six alleles per locus, and four of the loci cross-amplified in N. tenuissima. The mean observed and expected heterozygosity ranged from 0.00 to 0.90 and 0.00 to 0.50 per locus, respectively. Conclusions: The novel SSR markers are valuable for the study of genetic diversity of N. trichotoma and might also be useful for closely related species. PMID- 30276030 TI - Regeneration of highland papaya (Vasconcellea pubescens) from anther culture. AB - Premise of the Study: Vasconcellea pubescens is an important Caricaceae species cultivated in several countries of South America. The objective of this study was to investigate different media compositions and plant growth regulators to induce plant regeneration. Methods: Anthers were cultured in Murashige and Skoog medium with varying concentrations of naphthalene acetic acid (NAA) and 2,4 dichlorophenoxyacetic acid (2,4-D) plus a cytokinin (N-(2-chloro-4-pyridyl)-N' phenylurea). The effect of the basal medium supplemented with auxins and cytokinins on shoot regeneration from the induced calli was also evaluated. Addition of maltose to the basal medium was also tested. Results: The combination of 0.54 MUM NAA and 22.66 MUM 2,4-D induced the highest rate of calli formation. Regeneration via organogenesis was obtained in Murashige and Skoog and Woody Plant Medium supplemented with maltose and containing 8.88 MUM 6 benzylaminopurine, 5.71 MUM indoleacetic acid, and 2.28 MUM zeatin. Discussion: The plant regeneration protocol reported here permits the development of haploid and double haploid plants that can be useful for propagation purposes, allow a better molecular understanding of the species, and facilitate the production of new cultivars. PMID- 30276031 TI - NaOH low-salt method for chloroplast isolation and highly pure cpDNA preparation from Aeluropus littoralis. AB - Premise of the Study: High-yield pure chloroplast DNA (cpDNA) is necessary for whole genome sequencing. Chloroplast extraction with traditional high-salt methods causes damage to nuclei and destroys the integrity of organelles, which leads to high genomic contamination from the nucleus and mitochondria. To overcome this issue, we modified a traditional high-salt method to obtain a new approach called the NaOH low-salt method (NLS). Methods and Results: The NLS method is based on the mild alkaline lysis of plant cells, followed by homogenization with ultrasonic waves and fractionation under reduced osmotic pressure. Results showed that this modified protocol worked efficiently to extract the intact chloroplast from Aeluropus littoralis and other grasses to obtain high-quality pure cpDNA, which was confirmed by fluorescent microscopy, qPCR, and Illumina paired-end sequencing analysis. Conclusions: Compared with high-salt methods, the NLS method has proven robust for extraction of intact chloroplasts and preparation of high-yield pure cpDNA from grasses.

AB - Teaching junior residents, medical students and other hospital staff is an essential component of a resident physician's job. While resident physicians provide much of the teaching for their junior learners, few residents are provided with formal training on how to teach effectively. Although some Residents as Teachers (RAT) curricula do exist, there is no consensus on how the curriculum should be administered, content it should include, and how to assess its effectiveness. We seek to provide guidelines and recommendations applicable to any residency program seeking to begin or improve upon a RAT curriculum and provide suggestions on how to assess its effectiveness. PMID- 30276033 TI - Cerebral Fat Embolism: Neuroprotective Goals in an Unusual Cause of Altered Mental Status. AB - Cerebral fat embolism syndrome is a rare, but potentially lethal, complication that may arise from long bone fractures and/or orthopaedic surgery. Neurological symptoms are variable, and clinical diagnosis is difficult. We report the case of a 75-year-old woman who developed cerebral fat embolism four days after a right hip arthroplasty. Maintenance of intracranial pressure monitoring (ICP) within normal limits and cerebral tissue oxygenation monitoring (PbtO2) over 20 mmHg prevented secondary brain injury and resulted in a gradual improvement of the patient's sensorium. This case demonstrates that the use of ICP and PbtO2 monitoring defines optimal neuroprotective goals. PMID- 30276034 TI - Infusion-rate-dependent Acute Neuropathic Pain with Duopa in a Patient with Parkinson's Disease and Pre-existing Neuropathy. AB - The association of peripheral neuropathy (PN) with the cumulative use of levodopa, presumably by vitamin B12 deficiency, has been well-documented in the literature. However, less is known about the L-dopa infusion-rate-dependent precipitation of pre-existing peripheral neuropathy. We report an unusual case of Parkinson's disease in a patient who presented with acute exacerbations of pre existing peripheral neuropathy on exceeding certain rates of continuous Carbidopa Levodopa Infusions (CLI). We present a case of a 68-year-old gentleman with a 20 year history of idiopathic Parkinson's disease with bilateral subthalamic nucleus deep brain stimulation who was started on Duopa therapy for worsening dyskinesias. Workup before initiating Duopa was significant for idiopathic sensorimotor axonal polyneuropathy, although the symptoms were well controlled with medications. Subsequently, the patient developed severe neuropathic pain within 24 hours of initiating Duopa characterized by burning and stinging in his feet. Symptoms resolved within four hours of reducing the continuous infusion rates without modifying the bolus doses. The patient was doing well with extra bolus doses to manage off periods with no further recurrence of symptoms. With the support of this case report, we would like to conclude that the acute worsening of neuropathic pain with infusion rate or duration of treatment might limit the clinical benefits of Duopa and adds to the expanding spectrum of neurotoxic side effects associated with this therapy. Further prospective studies are needed to monitor the acute worsening of neuropathic pain in patients with pre-existing PN, after initiating CLI and its association with doses of levodopa/carbidopa. PMID- 30276036 TI - Percutaneous Trigger Thumb Release: Special Considerations. PMID- 30276035 TI - Closed Incision Negative Pressure Therapy in Oncological Breast Surgery: Comparison with Standard Care Dressings. AB - Background: Negative pressure wound therapy was developed for treating wounds associated with unfavorable healing factors. The principles of the negative pressure wound therapy applied on clean and closed surgical incision originate the closed incision negative pressure therapy (ciNPT). We evaluated the use of ciNPT in the setting of oncological breast surgery. Methods: From January 1, 2015, to June 31, 2015, we prospectively selected 37 patients undergoing oncological breast surgery with a minimum of 4 risk factors. Seventeen patients (25 surgeries) voluntary tested ciNPT (ciNPT sample), whereas the remaining 20 (22 surgeries) chose conventional postsurgery dressing (Standard Care sample). Follow-up controls to evaluate postsurgical complications were performed on days 7, 14, 30, and 90. At 12 months, the quality of life, scar, and overall aesthetic outcomes were evaluated with specific questionnaires filled in by surgeon and patient. The Standard Care sample was investigated on risk factors associated with poor healing. Results: The ciNPT sample showed a significant prevalence of high risk factors, especially extensive undermining and bilateral surgeries, and a predominance of women under 65 years; only 1/25 (4%) surgical procedures was followed by complications. In the Standard Care sample, 10 of 22 surgeries (45%) were followed by complications. The difference in complication rate between the 2 samples was significant. The BIS (Body Image Scale) scores suggested that most patients were satisfied with their body image regardless of the type of dressing. All other questionnaire scores clearly vouched for a significant superiority of the ciNPT. Previous surgery <= 30 days emerged as the surgery-related high risk factor most frequently associated with postsurgery complications. Conclusion: The results of our study support the use of ciNPT in oncological breast surgery: it showed to be a well-tolerated, adaptable, and reliable dressing capable of reducing postsurgical complications and improving scar outcomes in patients presenting with high risk factors.

PMID- 30276038 TI - Ten-year Follow-up After Treating Extended Burn Scar Contracture with an Autologous Cultured Dermal Substitute. AB - This is the first case report of long-term follow-up after applying the autologous cultured dermal substitute to establish the wound bed before split skin graft. The results suggest that application of autologous cultured cultured dermal substitute contributes to establish the high-quality wound bed for skin graft. Split-thickness skin grafts (STSGs) are the gold standard for the treatment of burn scar contracture. Young patients in particular may require additional skin grafts as they grow, and donor site for skin grafts may be limited. We applied autologous cultured dermal substitutes (CDSs) that are expected to establish a high-quality wound bed to allow thin STSGs. This is the first report of follow-up after application of autologous CDS combined with thin STSG. A male neonate suffered third-degree burns (20% of the total body surface area) on the back. After 2 years, scar contracture of the gluteal regions were released and autologous CDS were applied. Five days after the treatment, a super thin (4-6/1,000 per inch) skin grafting was performed. After 3 years, scar contracture of the back was released and autologous CDS was applied for 2 weeks. Then a split-thick graft was harvested from the same donor site. Ten years after the last operation, the width of the skin graft on his back has extended from 5-8 cm. The contour of the grafted skin is soft, smooth, and can be pinched. This long-term result shows the autologous CDS can be expected to establish the high quality wound bed that allows thin STSG. PMID- 30276039 TI - The Use of a Novel Local Flap Trainer in Plastic Surgery Education. AB - With the limitations of work hour restrictions and legal liability surgical resident's operative experience is declining. We sought to find other methods of training using tactile surgical simulations for plastic surgery. With the collaborative efforts of a local artist, a local flap trainer was designed to simulate the natural properties, layers, and interaction between layers of tissue. A session was held with Plastic Surgery faculty, residents, and students to review and practice local flaps using the trainer. Afterward, the participants filled out a survey evaluating the simulated skin and tissue model and the effectiveness of the class as a teaching model. The survey given had multiple questions asking the participant to provide a ranking from 1 to 10. The results show that the class utilizing the new suture pad was an effective teaching tool with an average score of 9.56. The suture pad was given a score of 6.77 for simulating realistic skin. Overall, the group rated increased understanding and confidence of local flaps after the class. Surgical skill simulations are becoming increasingly more important with the decline of resident operative experience. There are limited options for surgical simulations that provide a realistic experience. We designed a suture pad that is effective at simulating human tissue. The surveys show that using this suture pad in flap workshops provides a valuable teaching tool. PMID- 30276041 TI - Femoral Osteonecrosis after Medial Femoral Condyle Bone Graft Harvest. AB - The medial femoral condyle vascularized graft has become a useful resource in reconstructive microsurgery due to the rate of bony union, and the low rate of complication. We report osteonecrosis of the medial femoral condyle in a 65-year old woman after harvesting a corticocancellous medial femoral condyle graft to treat a tarsometatarsal nonunion. We were not able to define whether a vascular or mechanical disorder could be the ultimate cause. However, because of the severity of the complication, we suggest informing patients who will undergo a medial femoral condyle flap about this infrequent complication. PMID- 30276040 TI - McKissock's Reduction Mammaplasty Revisited: A Case Series Study with 12-months Follow-up. AB - Background: Reduction mammaplasty is 1 of the highly challenging yet demanded plastic surgeries worldwide. Different techniques have been described, and their modifications are always evolving to achieve better aesthetic results. The objective of the current study was to explore the efficiency and safety of bipedicled McKissock's technique with 3 newly added modifications as a reliable procedure for reduction mammaplasty. Methods: The study was conducted in Royal Hospital, Cairo, Egypt, during the period from January 2015 to October 2016. It included 25 female patients undergoing reduction mammaplasty. All patients were evaluated by detailed history, careful physical examination, and photographed pre and postoperatively. The new modifications included surgical undermining and thinning of the bipedicle for volume reduction and contour enhancement. The second modification was a dermal suspension of the lower pole for parenchymal support and longer breast shape stability. The third change was an S-shaped folding of the upper pole of the pedicle during nipple-areolar complex (NAC) transposition. After the operation, all subjects were followed up for 12 months to assess the outcomes of the procedure. Results: Twenty-five female patients were included in the analysis of this study. The age of the patients ranged from 22 to 49 years with a mean age of 36.2 (7.3) years. The mean body mass index was 30.5 +/- 4.3 kg/m2 with a minimum of 24 and a maximum of 38. The average time of operation was 4 hours. The resected tissue was 630-980 g. The optimal aesthetic appearance of the breasts was achieved at 6-9 months postoperatively and marinated to 12 months. The maintenance of improvement was measured by the distance between the mid-clavicular point and 12 O'clock point of the NAC (12'NAC). It varied between 28 and 43 cm preoperatively (mean +/- SD, 34.12 +/- 4.19 cm), and between 19 and 22 cm postoperatively (mean +/- SD, 20.70 +/- 1.03 cm; P < 0.001). The average percentage reduction in mid-clavicular point-NAC distance was 38.7% +/- 6.2% with a minimum reduction of 27.6% and a maximum 48.8%. Moreover, the nipple to inframammary crease distance varied between 16 and 20 cm preoperatively (mean +/- SD, 16.08 +/- 1.66 cm), and between 8 and 10 cm postoperatively (mean +/- SD, 8.04 +/- 0.79 cm; P < 0.001). The patients were very satisfied in most of the cases (20 cases), satisfied in 3 cases, and 2 cases were unsatisfied as they wanted slightly smaller breasts. No complications detected in 18 cases (72%), superficial wound dehiscence at the T-junction in 3 (12%), and seroma in 1 (4%). Two cases (8%) demanded smaller breasts and 1 case (4%) needed a surgical revision of widened scars after 11 months. The major drawbacks were NAC sensitivity alteration and the inability to lactate. Conclusion: We can conclude that our modifications for the McKissock's technique with its maintained aesthetic shape in those patients are a reliable option that can be considered, as it is a simple, efficient, and satisfactory method that can improve the results of reduction mammaplasty operations. PMID- 30276042 TI - Small Finger to Ring Finger Ray Transposition: Modern Surgical Technique and Case based Review of the Literature. AB - Ray transposition for central digital amputation has been performed following traumatic injury to the hand for decades. Small finger to ring finger ray transposition has been well described in the literature, with good functional and aesthetic outcomes reported. Originally described by Bunnell, the fourth metacarpal can be disarticulated and the fifth metacarpal base transposed with reconstruction of the intermetacarpal ligament allowing progressive closure between the third and fifth rays. However, osteotomy-based transpositions are utilized placing the osteotomy at the level of the metacarpal, followed by transposition and fixation of the small finger to the base of the ring finger metacarpal; or, by making an intracarpal wedge-osteotomy of the hamate with subsequent radial translocation of the entire small finger ray. Recent literature has suggested the intracarpal wedge osteotomy to be superior technically, and with less postoperative complications. However, for this somewhat uncommon reconstructive procedure, no high-level evidence exists to determine which of these techniques is truly more favorable. Here, we present an interesting case of ray amputation and transposition following an isolated fourth metacarpal traumatic firearm injury, and comprehensive modern surgical technique. Upon review of the literature, small to ring finger ray transposition has been shown to have acceptable functional and aesthetic outcomes regardless of the osteotomy technique used, and should be considered when the nature of presenting injury and the patient's lifestyle and postoperative expectations are appropriate. PMID- 30276044 TI - Reconstruction of the Lacrimal Excretory System in the Medial Canthal Region. AB - The resection of malignant tumors in medial canthal region may lead to full thickness defects including medial canthal ligament and lacrimal duct. There had been reports on various reconstructive methods, but none of those methods succeeded in lacrimal reconstruction with functional lacrimal excretory system. We experienced a case of conjunctival malignant melanoma at the lacrimal caruncle and performed new method of the reconstruction for full-thickness defects of the medial canthal region with the maintenance of the lacrimal drainage function. PMID- 30276043 TI - Evaluation of Safe and Effectiveness of an Injectable Solution Acid Deoxycholic Based for Reduction of Localized Adiposities. AB - Background: The use of deoxycholic acid to reduce localized fat deposits is a procedure that has been in use for about 30 years. Its effectiveness as treatment is due to emulsification of phospholipids and therefore, solubilization of the biological membranes with resulting fat necrosis. The purpose of the study was to assess the effectiveness and the safety of an injectable solution containing sodium deoxycholtate 1.25% (DB125), used as intralipotherapy. Methods: The effectiveness and safety of DB125 solution have been assessed with a multicentre observational prospective study carried out between February and October 2017. The 221 selected patients presented with various forms and degrees of localized fat in several areas. Intralipotherapy treatments were performed 6 weeks apart and until the clinical result was obtained. Aesthetic outcomes were evaluated by the authors using preoperative and postoperative photographic documentation and by the patients with their level of satisfaction by filling out an anonymous form. Major adverse events were reported by each doctor who performed the treatment. Results: Two hundred twenty-one patients treated in 273 cases of different localized fat deposits. One hundred eighty-five patients who could be assessed for final results gave the effectiveness of the treatment an average score of 7.4. The failure percentage of the treatment was 3.8%. The medical evaluation showed treatment success in 93.5% of cases. Adverse events can be divided into 2 groups: minor adverse events, which are very frequent and major ones, which are extremely rare. For both groups, the adverse events can be ascribed to localized problems in the treatment area. Conclusion: Studies have shown that the second-generation solution containing sodium deoxycholate 1.25% is effective and safe to treat different localized fat deposits. The high degree of effectiveness shown in the study was not associated with a lesser degree of handling because, at the doses indicated and with the use of intralipotherapy, the occurrence of adverse events was minimal. PMID- 30276045 TI - The Utility of a Master of Business Administration Degree in Plastic Surgery: Determining Motivations and Outcomes of a Formal Business Education Among Plastic Surgeons. AB - Background: With the increasing complexity of health care, the knowledge of business in medicine is growing more valuable. Plastic surgeons in all practice settings are constantly forced to navigate endeavors that could be better faced with the leadership, management, and administrative skills honed through a formal business education. The purpose of this study was to gather data and draw conclusions related to the motivations and outcomes of plastic surgeons with a Master of Business Administration degree (MBA). Methods: An online survey was distributed to plastic surgeons in the United States who have earned an MBA. The survey was divided into 4 main sections: demographics, MBA program description, objective assessment, and subjective assessment. Results: The majority of plastic surgeons with an MBA are in practice at an academic medical center. The 2 most popular tracks of completing the degree are during medical school and after 5 years of practice. A large proportion of plastic surgeons with an MBA experienced changes in their existing career position, namely in patient care and business roles outside of clinical practice. The most important skills surgeons subjectively felt they had improved as a result of their business education were in the areas of leadership, management, and administration. Conclusions: Overall, all the plastic surgeons felt that their MBA experience met their expectations and would recommend the degree to fellow physicians. Prime motivations included adding a new dynamic to their existing career, satisfying entrepreneurial drive, and gaining credibility in business, with monetary gains being low on the list. PMID- 30276046 TI - The Evolution from Subcutaneous to Prepectoral Prosthetic Breast Reconstruction. AB - Prosthetic breast reconstruction is the most common method of reconstruction offered to women following mastectomy. Prepectoral breast reconstruction has recently reemerged as an alternative technique to the partial and total muscle coverage methods. Though this technique has been demonstrated to be safe and effective in the recent published literature, many surgeons have been hesitant to adopt it out of fear of incurring the same complications associated with subcutaneous reconstructions of the past. However, recent advancements in plastic surgery including the use of acellular dermal matrices, autologous fat grafting, and improved breast implants and improved mastectomy techniques have enabled plastic surgeons to revisit the prepectoral space. In this review, the authors describe the evolution of prosthetic-based breast reconstruction from subcutaneous to prepectoral and review outcomes. PMID- 30276047 TI - The Safety, Cosmetic Outcome, and Patient Satisfaction after Inferior Pedicle Reduction Mammaplasty for Significant Macromastia. AB - Background: Significant macromastia is socially and physically debilitating. Reduction mammaplasty in these cases carries significant morbidity. Methods: Cases of inferior pedicle reduction mammaplasty performed at the breast unit, King Fahd Hospital, Jeddah, Saudi Arabia, over the last 10 years were reviewed. Inclusion criteria were cases with significant macromastia in which the distance from the supra-sternal notch to the nipple was >= 40 cm. Results: There were 26 cases of inferior pedicle reduction mammaplasty done for significant macromastia. The average age was 34.56 years (range, 16-56 years). The average sternal notch to the nipple distance was 43.08 cm (range, 40-49 cm). The average amount of breast tissue removed from the right breast was 1,057.6 g (range, 495-2,450) and from the left breast was 959.4 g (range, 445-2,100). Postoperatively, 4/26 (15.4%) had ecchymosis, 9/26 (34.6%) developed T-junction sloughing, 2/26 (7.7%) had wound infection, and 1/26 (3.8%) had unilateral partial nipple-areola complex ischemia. In 7/26 (26.9%), scars were evident and revision was performed in 4/26 (15.4%) cases. Variable degrees of upper breast flattening and bottoming were seen in most cases; however, these variations were more profound in fatty breasts and longer pedicles. The average follow-up period was 26.04 months (range, 3-68 months). All patients were satisfied with the reduced breast heaviness, but only 19/26 (73.1%) were highly satisfied with the breast shape and scars. Conclusions: In cases of significant macromastia, inferior pedicle reduction mammaplasty is a safe procedure. Evident scars, upper breast flattening, and bottoming adversely affect the level of satisfaction. PMID- 30276048 TI - Isotopic Split-skin Graft for Resurfacing of Deliberate Self-harm Scars. AB - We present a novel surgical approach for the revision of deliberate self-harm scars. The isotopic skin graft technique employs the harvest of a thin split-skin graft from the affected area, excision and closure of wide dermal scars with replacement of the graft back onto the harvest site. We present the sequential steps of the surgical technique and a case series of 2 patients treated with our novel approach. PMID- 30276050 TI - Maxillary Reconstruction Using a Gullwing Fibula Osteofascial Flap and Flexor Hallucis Longus Muscle. AB - The appropriate reconstruction of an infrastructure maxillectomy defect requires vascularized bone for maxillary arch restoration, soft tissue bulk for filling the residual defect extending up to the orbital floor, and a thin tissue layer for resurfacing the palate and adjacent cheek mucosa. Although several free tissue flaps have been previously described as reconstructive options, each possesses limitations. We describe the fibula osteofascial flap with flexor hallucis longus muscle, no skin paddle, and a "gullwing" fascial component, as an ideal reconstructive option for these specific maxillary defects. It satisfies the necessary requirements of bone, restoration of intraoral surfaces, as well as additional soft tissue volume to provide the optimal aesthetic and functional result. It also has the added benefit of minimizing morbidity to, and improving aesthetics of, the donor site. This is demonstrated through a case presentation and review of the existing literature. PMID- 30276049 TI - Fat Grafting Can Induce Browning of White Adipose Tissue. AB - Background: Fat grafting is commonly used when treating soft-tissue defects. However, much of the basic biology behind fat transfer is still uncovered. Adipocytes can be divided into energy storing white and energy burning brown adipose cells. It is now well known, that also adult humans have metabolically active brown adipose tissue (BAT) within white adipose tissue (WAT). Previously our group showed that transfer of metabolically inactive WAT into a new environment increased the metabolic activity of the fat grafts to resemble the activity in the recipient site and that different WAT depots have variation in the metabolic activity. This led us to speculate, whether the metabolic increase of the graft is a result of "browning" of the transferred WAT toward beige adipose tissue. Methods: We investigated the metabolic and histological characteristics and BAT marker Ucp1 gene expression in different types of WAT grafts placed either in subcutaneous or muscle tissue in mice. Metabolic activity of the grafts was investigated by FDG-PET/CT at 4- and 12-week time-points. Results: The glucose uptake of all transferred fat types was increased when compared with respective control WAT regardless of transfer location. Ucp1 gene and protein expression was increased in 4 of 15 intramuscularly placed fat graft samples and showed histological resemblance to BAT with multilocular cells. Conclusions: Grafting of metabolically inactive fat intramuscularly may induce browning of fat grafts toward more active beige adipose tissue. This opens up new research areas in exploiting fat grafting in metabolic diseases. PMID- 30276051 TI - Institutional Collaboration in Plastic Surgery Research: A Solution to Resource Limitations. AB - Background: The current climate of health care reform and research funding restrictions presents new challenges for academic plastic surgery. Collaboration with private enterprise has been associated with greater research productivity in the general biomedical literature. This study seeks to analyze publication trends in Plastic and Reconstructive Surgery (PRS) to evaluate any changes in institutional collaboration over time. Methods: Bibliographic data were retrospectively analyzed for all original research and discussion articles published in PRS from 2012 to 2016. The institutional affiliation for each publication was characterized from its author list as solely academic, private, government, or combinations of these (defined here as "institutional collaborations"). Annual National Institutes of Health (NIH) funding data were also collected over the same period, and associations were analyzed by linear regression. Results: In total, 2,595 publications were retrieved from PRS between 2012 and 2016, of which 2,027 (78.1%) originated solely from academic institutions and 411 (15.8%) from institutional collaborations. Although the proportion of academic-only publications decreased from 82% to 74%, the proportion of institutional collaborations increased from 10% to 20% (P = 0.038). Concurrently, NIH funding declined from $33.4 billion to a low of $30.7 billion, which was associated with the decreasing proportion of academic-only publications (P = 0.025) and increasing proportion of institutional collaborations (P = 0.0053). Conclusions: Traditional sources of academic research funding have been restricted during the politically and financially tumultuous recent years. With no signs of improving access to financial resources from the NIH, academic plastic surgeons may consider diversifying their institutional partnerships to continue pioneering advances in the field. PMID- 30276053 TI - A Prospective Study Investigating Fistula Rate Following Primary Palatoplasty Using Acellular Dermal Matrix. AB - Background: Acellular dermal matrix (ADM) has been described as an adjunct in primary cleft palate repair to reduce the fistula rate in several retrospective studies (level III or lower); however, current data are insufficient to definitively conclude its efficacy for this purpose. The goal of the present study was to provide prospective, higher level of evidence data investigating the effect of ADM on fistula rate following primary palatoplasty. Methods: A prospective clinical trial was conducted in which ADM was used uniformly in all primary cleft palate repairs that met inclusion criteria. For comparison, a matched control group was identified (retrospectively) from the same center/surgeon's database. Primary outcome was the rate of palatal fistula formation. Secondary outcomes included bleeding, infection, and delayed healing. Results: A total of 130 patients were included in the analysis consisting of 65 in both the study and control groups. There were no statistically significant differences in patient demographics or cleft /surgical characteristics. The results demonstrated a fistula rate of 1.5% in the study group versus 12.3% in the control group (P = 0.03). The other complications (infection, bleeding, delayed healing) were similar between the groups. Conclusion: The study provides the highest level of evidence currently available (level II, prospective data) investigating the effect of ADM on fistula rate following primary palatoplasty. The results demonstrate a low overall fistula rate (1.5%) and suggest there may be a clinically significant reduction in fistula formation associated with the routine use of ADM in all primary palate repairs. PMID- 30276052 TI - Ex Vivo Major Histocompatibility Complex I Knockdown Prolongs Rejection-free Allograft Survival. AB - Background: Widespread application of vascularized composite allotransplantation (VCA) is currently limited by the required lifelong systemic immunosuppression and its associated morbidity and mortality. This study evaluated the efficacy of ex vivo (after procurement but before transplantation) engineering of allografts using small interfering RNA to knockdown major histocompatibility complex I (MHC I) and prolong rejection-free survival. Methods: Endothelial cells (ECs) were transfected with small interfering RNA targeted against MHC-I (siMHC-I) for all in vitro experiments. MHC-I surface expression and knockdown duration were evaluated using quantitative polymerase chain reaction (qPCR) and flow cytometry. After stimulating Lewis recipient cytotoxic lymphocytes (CTL) with allogeneic controls or siMHC-I-silenced ECs, lymphocyte proliferation, CTL-mediated and natural killer-mediated EC lysis were measured. Using an established VCA rat model, allografts were perfused ex vivo with siMHC-I before transplantation. Allografts were analyzed for MHC-I expression and clinical/histologic evidence of rejection. Results: Treatment with siMHC-I resulted in 80% knockdown of mRNA and 87% reduction in cell surface expression for up to 7 days in vitro (P < 0.05). Treatment of ECs with siMHC-I reduced lymphocyte proliferation and CTL-mediated cytotoxicity (77% and 50%, respectively, P < 0.01), without increasing natural killer-mediated cytotoxicity (P = 0.66). In a rat VCA model, ex vivo perfusion with siMHC-I reduced expression in all tissue compartments by at least 50% (P < 0.05). Knockdown prolonged rejection-free survival by 60% compared with nonsense treated controls (P < 0.05). Conclusions: Ex vivo siMHC-I engineering can effectively modify allografts and significantly prolong rejection-free allograft survival. This novel approach may help reduce future systemic immunosuppression requirements in VCA recipients. PMID- 30276054 TI - Efficacy of Cultured Epithelial Autograft after Curettage for Giant Melanocytic Nevus of the Head. AB - Cultured epithelial autograft (CEA) is an epithelial sheet prepared from a patient's own skin using cell culture. In Japan, CEA (JACE; Japan Tissue Engineering Co., Ltd., Gamagori, Japan) was approved and covered by public health care insurance for use in the treatment of giant congenital melanocytic nevus (GCMN) in 2016. There are several treatment options for GCMN; however, the complete removal of a GCMN is usually difficult due to the lack of skin. In this report, we describe a case of GCMN in the occipital region that was treated using CEA after curettage. A 2-month-old boy had a GCMN of 13 * 21 cm in his occipital region. We used full-thickness skin taken from the back of the right auricle to prepare CEA under general anesthesia at 4 months of age. Three weeks after preparing CEA, we performed curettage of the right half of the GCMN, and CEA was grafted onto the wound afterward. CEA took completely, and epithelization was observed at 10 days after surgery. We then performed curettage with subsequent grafting of CEA on the left half of the GCMN at 7 months of age. CEA took completely, and epithelization was observed in this procedure as well with no hair loss at 8 months of age. Whether or not curettage can reduce the risk of malignant transformation into malignant melanoma of GCMN is unclear; however, the application of CEA after curettage may be a promising option for obtaining early epithelization. PMID- 30276055 TI - Robotic Nipple-sparing Mastectomy and Immediate Breast Reconstruction with Gel Implant. AB - Background: The experience of application of robotic surgery platform in the management of breast cancer was limited. The preliminary experience and results of robotic nipple-sparing mastectomy (R-NSM) and immediate breast reconstruction (IBR) with Gel implant was reported. Methods: The medical records of patients who underwent R-NSM and IBR with Gel implant for breast cancer during the period March 2017 to October 2017 were collected from single institution. Data on clinicopathologic characteristics, type of surgery, method of breast reconstruction, complications, and recurrence were analyzed to determine the effectiveness and oncologic safety of R-NSM. Patients' oriented cosmetic outcome report was also obtained. Results: A total of 15 patients was analyzed, and the mean age of them was 46.5 +/- 10.0 years. The pathologic stage was 30.8% ductal carcinoma in situ, 30.8% stage I, 30.8% stage II, and 7.7% stage III. The mean operation time was 282.8 +/- 70.4 minutes, and mean hospital stay was 6.7 +/- 1.2 days. The positive surgical margin rate was 0%. One patient suffered from delayed axillary wound healing. Two patients (13.3%) with transit nipple ischemia change, but no total nipple areolar complex necrosis case was observed. No local recurrence, distant metastasis, or case mortality was found during mean 6.3 +/- 2.1 months follow-up. All 15 patients were satisfied with the postoperative aesthetic outcome. Conclusion: From our preliminary experience, R-NSM and IBR with Gel implant is a safe procedure, with good cosmetic results, and could be a promising new technique for breast cancer patients indicated for mastectomy. PMID- 30276056 TI - Treatment Delay Impact on Open Reduction Internal Fixation of Mandibular Fractures: A Systematic Review. AB - Background: The impact of mandible fracture treatment delay has been contested in the literature for decades, with conventional wisdom favoring earlier surgical treatment to prevent postoperative complications, primarily infection. Through a systematic review of all available evidence, this study aims to determine whether delay to open reduction and internal fixation of traumatic mandibular fractures influences outcomes. Methods: MEDLINE, EMBASE, CINAHL, and Web of Science were systematically searched for English language literature pertaining to the above research question and screened in duplicate. Methodological quality scoring was performed using MINORS criteria. Qualitative and quantitative findings from relevant studies are presented. Results: Twenty eligible studies including 2,671 patients had open reduction internal fixation, with or without adjunct mandibulomaxillary fixation. All studies were observational cohort or case control studies of low methodological quality with a mean MINORS score of 6.5 of 16 (40.6%) for noncomparative studies and 11.2 of 24 (46.7%) for comparative studies. Only 5 of 20 (25%) studies recommended earlier treatment. Due to insufficient reporting of data and study heterogeneity, the impact of treatment delay on complications could not be quantitatively analyzed. Conclusions: There is substantial heterogeneity and no consensus on the definition of "early" versus "delayed" surgical treatment for patients with traumatic mandibular fractures. The majority of included studies do not make a recommendation for earlier treatment. Future, well-designed prospective studies are essential to determine if there is an optimal surgical treatment delay of mandibular fractures that mitigates the risk of infectious and noninfectious complications. PMID- 30276057 TI - Accuracy of Predicted Resection Weights in Breast Reduction Surgery. AB - Background: Many insurance carriers continue to deny coverage for reduction mammaplasty unless a minimum amount of resected breast tissue per breast is achieved during surgery. This study investigates the accuracy of preoperative prediction that a minimum weight of 500 g can be resected and evaluates potential risk factors for not meeting this insurance requirement. Methods: A retrospective review was performed on 445 patients with bilateral symptomatic macromastia who sought consultation for breast reduction surgery from 2007 to 2012. Women were included for analysis if they had documented predicted resection weights and underwent small-to-moderate breast reduction (< 1,000 g per side; n = 323). Relevant demographic information, mean predicted resection weight, and the mean actual resection weight were collected for analysis. Results: Surgeon prediction of resection weight being over 500 g had a positive predictive value of 73%. In 61 patients (19%), the predicted weights were >= 500 g, but the actual weights were < 500 g. Thirty percentage of these 61 patients did not meet either Schnur or minimum weight requirements. Women with a body mass index < 30 were at significantly increased odds (odds ratio, 3.76; 95% confidence interval, 1.89 7.48; P = 0.002) of not meeting the minimum weight requirement at surgery compared with patients with a body mass index >= 30. Conclusions: The common insurance criterion of removing >= 500 g per breast during breast reduction surgery are not met in a distinct cohort of women who are clinically appropriate candidates. This risk is particularly increased in nonobese women possibly due to proportionately smaller breast mass compared with obese women. PMID- 30276058 TI - Prevalence and Distribution of Potential Vascularized Composite Allotransplant Donors, Implications for Optimizing the Donor-recipient Match. AB - Background: Vascularized composite allotransplantation (VCA) is an emerging and growing field. Little is known about the prevalence and distribution of the adult potential donor population in the United States now that it falls under the oversight of the United Network for Organ Sharing (UNOS). Methods: We assessed the UNOS database from 2008 to 2015 to estimate the prevalence and distribution of adult potential vascularized composite allograft donors. Donor inclusion and exclusion criteria were developed in a way to minimize risk to recipients and were applied to the dataset. Donors were categorized by factors that influence vascularized composite allograft matching including ABO blood type, cytomegalovirus status, and ethnicity (correlate for skin color) and sorted by UNOS region. Results: Just under half of all brain dead donors met the inclusion/exclusion criteria. Blood type O, cytomegalovirus+, White donors represented the most frequent donor profile while blood type AB, cytomegalovirus , Asian donors were the least common. UNOS region 3 had the most and region 1 had the least potential VCA donors per year. Nearly all potential VCA donors were solid organ donors with the liver being the most commonly donated solid organ in this population. Conclusions: A large portion of the solid organ donor pool would qualify as adult vascularized composite allograft donors in the current UNOS system. These data will assist transplant teams in determining the prevalence and distribution of vascularized composite allograft donors for their individual patients awaiting composite allografts based on relevant matching characteristics in addition to standard transplant criteria. PMID- 30276059 TI - Effect of Keller Funnel on the Rate of Capsular Contracture in Periareolar Breast Augmentation. AB - Background: Capsular contracture is 1 of the most common complications after breast implant surgery and is a major indication for reoperation. Capsular contracture is believed to be a multifactorial process that is affected by implant texture, incision type, and ultimately pocket contamination. This contamination causes a biofilm that leads to capsular contracture. The intraoperative use of a Keller funnel is a mechanical way to decrease the implant's contact with the skin and ducts, reducing bacterial contamination that can cause these biofilms. For this reason, periareolar breast augmentation has been less popular among surgeons. The purpose of this study was to examine if there was a significant difference between the rates of capsular contracture in patients having periareolar breast augmentations with the use of a Keller funnel for insertion and those having periareolar breast augmentations without Funnel use. Methods: This level 3 retrospective study followed 2 groups of patients, the first having periareolar breast augmentations without the use of a funnel for insertion (group A; patients n = 15; implants n = 30) and the second having periareolar breast augmentations with the use of a funnel for insertion (group B; patients n = 151; implants n = 300). Results: The rate of capsular contracture in group A was found to be 10% compared with a rate of capsular contracture of 1.3% for patients in group B, an 87% reduction (P = 0.0019). Conclusions: According to the results found in this study, the rate of capsular contracture in patients having periareolar breast augmentations after insertion with a Keller funnel was statistically significantly lower than the rate in patients having implants inserted without the assistance of a funnel, making the device useful in reducing the occurrence of postoperative capsular contracture. PMID- 30276060 TI - Peroneal Nerve Repair of a 9 Year Old: Return of Motor Function after 2 Years. AB - Major factors that influence functional nerve recovery, postrepair, are length of the nerve defect, type of injury, operative technique, time until treatment, and age of the patient. We present a severe motor nerve defect in a complicated peroneal nerve injury in a 9-year-old that showed functional return after a delayed period of 23 months with sural nerve cable grafting. This case revealed the increased resiliency and regenerative capacity of motor end plates in young patients. In conclusion, autograft for a deep peroneal nerve repair, by means of sural nerve graft, proved to be an acceptable option in children. PMID- 30276061 TI - Miniature Negative Pressure Dressings on Forearm Donor Sites after Radial Forearm Flap Harvest. AB - Management of radial forearm donor sites following free flap reconstruction of head and neck tumor defects typically requires split-thickness skin grafting. Tendon exposure and delayed healing are occasional problems associated with skin grafting over the distal forearm musculature. Others have reported the use of negative pressure wound therapy (NPWT) devices to bolster split-thickness grafts and improve graft take. Although this approach works well, these devices are not always approved by third-party payers for outpatient use, requiring patients to remain in the hospital or have these devices removed before discharge. The authors report outcomes using a miniaturized NPWT device to bolster the skin graft on radial forearm free flap donor sites in 10 consecutive patients compared with 10 consecutive control patients managed with traditional bolster dressings. The 2 groups of patients were similar in terms of demographics, indication for reconstruction, and size of donor site. There was less skin graft loss and a lower rate of tendon exposure and infection in the miniaturized NPWT device group, though these results did not reach statistical significance. Recently developed miniaturized, single-use NPWT devices can be reliably used as bolsters for skin grafts with some notable advantages over reusable NPWT devices. PMID- 30276062 TI - Composite Grafts for Pediatric Fingertip Amputations: A Retrospective Case Series of 100 Patients. AB - Background: Fingertip amputations are common. This study reports on the outcomes of composite grafts used for fingertip amputations in children, measuring graft take, predictors of graft take, complications, and patient-reported outcomes. Methods: A retrospective case series of consecutive patients (<= 16 years) undergoing composite grafts for fingertip amputations in a tertiary pediatric hospital, January 06 to December 16, was performed. Information was collected on amputations, graft take, and complications. Logistic regression was used to analyze factors predicting graft take (partial/complete or failure) including age; amputation level; mechanism and time delay to surgery. Patients were contacted via post or telephone to ask about functional and cosmetic outcomes and their perception of graft take. Results: One hundred patients [57 (57%) males; mean age, 4.41 +/- 3.98 years], presenting with 100 fingertip amputations, met the inclusion criteria. Amputation mechanism was crush in 75 (75%), avulsion in 13 (13%), and laceration in 12 (13%). Thirteen (13%) composite grafts survived completely, 46 (46%) partially, and 41 (41%) failed. Graft survival was higher in children under 4 years (P = 0.016). Seventeen (17%) grafts became infected, 9 (9%) required a reoperation, 9 (9%) had wound healing complications, and 4 (4%) patients developed psychological complications. Patient-reported survival was 33% higher than medical-reported survival. Cosmetic issues were the commonest complication reported by patients. Patients rated fingertips looking 3.5/5 normal, and that they were 4/5 satisfied with the appearance. Most patients were using their fingers normally by 2-6 months. Conclusions: Composite grafts for fingertip amputations mostly only partially survive, but morbidity is low, patient satisfaction is high, and acceptable cosmetic and functional outcomes are achieved. PMID- 30276063 TI - Photometric Evaluation of Long-term Changes in Breast Shape after Breast Augmentation and Vertical Mammaplasty. AB - Background: Little information is presently available regarding the long-term effects of breast augmentation and mammaplasties on breast shape. Existing studies typically use 1-dimensional measurements and mean follow-up times seldom exceed 1 year. Methods: Twenty women were studied: breast augmentation (n = 5), mastopexy (n = 5), augmentation/mastopexy (n = 5), and breast reduction (n = 5). For mammaplasties, a vertical method using a medial pedicle and intraoperative nipple siting was used in all cases. A 2-dimensional measurement system was used, with computer-assisted matching of lateral photographs of the right and left breasts. Measurements were evaluated at 3 times: before surgery, 1 year after surgery, and 10 years after surgery. Results: Breast implants significantly increased breast projection and upper pole projection. The nipple level was unchanged. The lower pole level dropped. These changes were preserved at 10 years. Vertical mastopexy provided a modest increment in breast projection and upper pole projection. The nipple level and lower pole level were raised significantly. Augmentation/mastopexy boosted breast projection and upper pole projection, and also elevated the nipple and lower pole level. Breast reduction changes were similar to mastopexy, but with greater elevation of nipple level and lower pole level, which were usually lower to start with. Implants increased upper pole convexity. Nipple overelevation was avoided by intraoperative nipple siting just below the breast apex. Conclusions: These measurements provide new information regarding the long-term effects of breast augmentation and vertical mammaplasties. This information may be used by plastic surgeons in procedure selection and patient counseling. PMID- 30276064 TI - Efficacy and Safety of Intravenous Meloxicam in Subjects with Moderate-to-severe Pain Following Abdominoplasty. AB - Background: A nanocrystal intravenous (IV) formulation of meloxicam is being studied with the aim of providing postoperative analgesia. Methods: This randomized, multicenter, double-blind, placebo-controlled trial evaluated meloxicam IV 30 mg or placebo (<= 3 doses) in 219 subjects undergoing abdominoplasty. The primary endpoint was the summed pain intensity difference over 24 hours postdose (SPID24). Results: Meloxicam IV-treated subjects had a statistically significant reduction in the least squares mean of SPID24 compared with placebo-treated subjects (-4,262.1 versus -3,535.7; P = 0.0145). Meloxicam IV was associated with statistically significant differences over placebo on several other secondary endpoints, including other SPID intervals (ie, SPID12, SPID48, and SPID24-48), achievement of perceptible pain relief, the proportion of subjects with a >= 30% improvement in the first 24 hours, and Patient Global Assessment of pain at hour 48. Meloxicam IV was also associated with a reduction in the number of subjects receiving opioid rescue medication during hours 24-48 and the total number of doses of opioid rescue analgesia. Meloxicam IV was generally well tolerated, with the numbers and frequencies of adverse events similar to that of the placebo group. There was no evidence of an increased risk of adverse events commonly associated with nonsteroidal anti-inflammatory drugs including bleeding, thrombotic, cardiovascular, renal, hepatic, cardiovascular, injection site, and wound healing events. Conclusion: Meloxicam IV provided sustained pain relief and generally was well tolerated in subjects with moderate to-severe pain following abdominoplasty. PMID- 30276065 TI - Glans Ischemia after Circumcision in a 16-Year-Old Boy: Full Recovery after Angiography with Local Spasmolysis, Systemic Vasodilatation, and Anticoagulation. AB - Circumcision is one of the most frequent procedures performed by pediatric surgeons. A dorsal penile nerve block (DPNB) is commonly used for perioperative analgesia. We report the case of a 16-year-old boy with ischemia of the glans who presented on the first postoperative day after circumcision under DPNB (0.25% bupivacaine) at an outside hospital. The patient underwent immediate angiography under sedation. An intra-arterial spasmolysis was performed with alprostadil and nitroglycerine and a sufficient perfusion of the glans penis was confirmed. Subsequently, systemic sildenafil, arginine, and heparin were given. Following this 3-day medical treatment, ischemia resolved completely. Our case emphasizes the role of invasive angiography in the diagnostic workup and the therapeutic possibilities of local spasmolysis, systemic vasodilatation, and anticoagulation. PMID- 30276066 TI - Prevalence and Factors Affecting Cervical Deformity in Adolescent Idiopathic Scoliosis Patients: A Single-Center Retrospective Radiological Study. AB - Background: It has been reported that adult spinal deformity patients have a high prevalence of cervical kyphosis (CK) and cervical positive sagittal malalignment (CPSM). However, the prevalence and possible factors affecting CK and CPSM in patients with adolescent idiopathic scoliosis (AIS) are less clear. Methods: We retrospectively analyzed a consecutive series of AIS patients from a single center. Radiographic measurements included the Cobb angle, C2-C7 sagittal vertical axis (C2-C7SVA), and C2-C7 lordosis. Cervical deformity was defined as loss of lordotic or neutral cervical angle (CK) or C2-C7SVA more than 4 cm (CPSM). Patients were stratified by the degree of thoracic kyphosis and coronal thoracic curve. Results: A total of 99 patients were included in this study. The patients' mean age was 14 years (range, 10-18 years). Mean cervical lordosis and C2-C7SVA were 1.5 degrees and 30.4 mm, respectively. The CK and CPSM prevalence were 49% and 16%, respectively, and prevalence of CK and/or CPSM was 59%. CK was present in 32% of the patients who had >20 degrees thoracic kyphosis, and it was present in 75% of the patients who had <=20 degrees thoracic kyphosis (P = .003). No association between CPSM and thoracic kyphosis was found. The patients who had >20 degrees coronal thoracic curve had higher CK prevalence (64% versus 37%, P = .05), but no CPSM association was found. Conclusions: Cervical deformity is highly prevalent in AIS patients. There is a significant correlation between the loss of thoracic kyphosis and the development of CK but not the development of CPSM. High coronal thoracic curve is associated with CK prevalence, but it is not associated with CPSM prevalence. PMID- 30276067 TI - Facet Sparing Foraminal Decompression Using the Flexible Shaver Foraminotomy System: Nerve Safety, Pain Relief, and Patient Satisfaction. AB - Background: A number of surgical options exist for decompressing lumbar foraminal stenosis. Flexible shaver foraminotomy is a recent addition to this armamentarium. While the foraminotomy device has been incorporated into clinical practice, the literature on its safety and efficacy remain limited. We aimed to evaluate nerve safety, pain relief, and patient satisfaction in a series of patients treated with the iO-Flex shaver system (Amendia, Inc., Marietta, Georgia). Methods: Thirty-one consecutive patients with lumbar foraminal stenosis underwent foraminal decompression using the flexible microblade shaver system at 62 neuroforamina. The shavers were inserted into each foramen using an open hemilaminotomy and fluoroscopic guidance. Nerve mapping via mechanomyography (MMG) was used to ensure nerve safety. Perioperative charts were reviewed to find the incidence of neurologic complications and to quantify pain relief. Average office-based follow-up was 5.3 months. A 3-item questionnaire was administered to assess patient satisfaction during late follow-up, which occurred at an average of 21 months. Results: No planned iO-Flex foraminotomies were aborted. Neurologic complications included transient dysesthetic pain in 1 patient (3.2%, n = 31), and transient numbness in 3 patients (9.7%, n = 31). There were no motor deficits. The composite nerve complication rate was 12.7%. Preoperative visual analog scale scores decreased from a mean of 7.1 (n = 31, standard deviation [SD] 2.0) to a mean of 3.5 (n = 30, SD 2.5). If asked to repeat their decision to do surgery, 81% of patients would redo the procedure. The rate of patient dissatisfaction was 19%. Conclusions: Decompression of lumbar foramina using the flexible shaver system and MMG nerve mapping is safe and effective, although the short-term sensory complication with this technique may be higher than previously reported. Patient satisfaction with iO-Flex foraminotomy is comparable to reported satisfaction outcomes for traditional lumbar decompression. Level of Evidence: 4. PMID- 30276068 TI - Endoscopic Transforaminal and Lateral Recess Decompression After Previous Spinal Surgery. AB - Background: Leg pain and back pain after lumbar laminectomy and spinal decompression fusion surgery are common and often related to persistent lumbar foraminal or lateral recess stenosis. Although persistent symptoms often stem from incomplete decompression during the primary index surgery, recurrent symptoms may also be the result of intervertebral cage subsidence due to loss of intervertebral and neuroforaminal height. Objective: The aim of this study was to investigate the feasibility of using the outpatient transforaminal decompression procedure as an alternative to inpatient open procedure in revision decompression surgery, with the intent of minimizing the incidence of perioperative and postoperative surgical complications while reducing both direct and indirect costs of surgical treatment, shortening time to patient postoperative narcotic independence, and shortening time of patient return to daily activities. Methods: A total of 48 patients with conclusive diagnostic imaging and interventional workup underwent endoscopic transforaminal and lateral recess decompression for both persistent or recurrent leg and/or low back pain following previous lumbar laminectomy (22 patients) or decompression fusion surgery (26 patients). In addition to radiographic studies, patients were followed for a minimum of 2 years postoperatively, and clinical outcomes were evaluated with the visual analog scale (VAS), Oswestry Disability Index (ODI), and modified Macnab criteria. Results: At final follow-up, patients with single- and 2-level prior surgeries reported an average ODI reduction following their secondary surgery of 44.6%, with an average final score of 14.8. Less favorable ODI score reductions following secondary surgery (23.8%) were reported by patients who had more than one or a complex prior multilevel surgery. According to the modified Macnab criteria, "excellent" and "good" results were obtained with the secondary surgery in 79.1% (38 of 48) of patients with no more than a single 1- or 2-level prior lumbar surgery. The mean VAS score decreased from 7.7 +/- 1.8 preoperatively to 2.3 +/- 1.1 at final follow-up (P < .01). Fair and poor results with the secondary surgery were seen in 20.9% (10 of 48) of patients with several prior surgeries or complex multilevel previous lumbar surgeries. The level distribution for secondary surgery was as follows: L4-5 segment (26 levels; 54.1%), L5-S1 (14 levels; 29.2%), L3-4 (7 levels; 14.6%), and the L2-3 level (1 level; 2.1%). Postoperative complications were limited to irritation of the dorsal root ganglion, which occurred in 25% (12 of 48) of patients. There were no wound infections, nerve root injuries, foot drop, or admissions to a hospital for further postoperative care. All patients with "excellent" and "good" outcomes measured by modified Macnab criteria, who were working before and after the primary and secondary surgeries (27 of 38), reported earlier return to work after the endoscopic outpatient surgery (2.6 +/- 0.8 weeks) than with the prior inpatient open spinal surgery (8.1 +/- 4.5 weeks). Based on the 2012 Medicare fee schedule for professional fees, direct costs were 40.6% and indirect costs were 37.1% lower with the secondary endoscopic surgery compared with primary open surgery. Conclusions: Transforaminal decompression is an effective alternative to open revision lumbar spinal surgery to treat symptomatic spinal stenosis after previous lumbar surgery in patients with persistent or recurrent leg and low back pain. It can be safely done in an outpatient setting, while realizing savings in direct and indirect costs. PMID- 30276069 TI - Computerized Tomography-Based Morphometric Analysis of Subaxial Cervical Spine Pedicle in Asymptomatic Indian Population. AB - Background: The purpose of this study was to analyze morphometry of the subaxial cervical spine pedicles in an Indian population based on computed tomography (CT), and thus assess the safety and feasibility of cervical pedicle screw in the subaxial cervical spine. Methods: CT scans of 500 subaxial cervical spine vertebrae were analyzed from 100 patients presenting to our institution and undergoing cervical spine CT scan for an unrelated cause as part of ATLS protocol. Pedicle width (PW), pedicle axis length (PAL), pedicle transverse angulation (PTA), and lateral pedicle distance (LPD) were calculated on axial CT scans, and pedicle height (PH), pedicle length (PL), superior pedicle distance (SPD), and pedicle sagittal angulation (PSA) were calculated on sagittal CT scans. Results: The mean PW ranged from 4.3 mm at C3 to 5.7 mm at C7. Mean PH ranged from 5.5 mm at C3 to 6.1 mm at C7. Mean PTA ranged from 44.5 degrees at C3 to 37.1 degrees at C7. PSA ranged from 16.65 degrees at C3 to 3.29 degrees at C7. Mean LPD ranged from 1.6 mm at C3 to 3.4 mm at C6. Mean SPD ranged from 3.5 mm at C3 to 1.15 mm at C7. Mean PAL ranged from 29.6 mm at C3 to 33.04 mm at C7. Mean PL ranged from 5.2 mm at C3 to 5.78 mm at C7. Conclusions: Our CT-based morphometric study confirms that cervical pedicle screw placement is possible in most of the Indian population except at C3 in females. A thorough understanding of pedicle anatomy with proper CT-based preoperative planning can mitigate the risk associated with pedicle screw placement in subaxial cervical spine. PMID- 30276070 TI - Cervical Myelopathy Secondary to Combined Ossification of Ligamentum Flavum and Posterior Longitudinal Ligament-A Case Report. AB - In the cervical spine, the combined ossification of the ligamentum flavum (OLF) and posterior longitudinal ligament is rarely seen. Patients are usually treated with cervical laminectomy or laminoplasty with OLF resection. In most of the cases, OLF is adhered to the dura and there is a risk of dural tear or cerebrospinal fluid (CSF) leakage during its resection. In this case report, the authors present results of laminectomy with debulking instead of complete excision of OLF for spinal cord decompression in a cervical myelopathy case in which OLF was adhered to the dura. A 69-year-old man presented with insidious onset weakness in bilateral lower limbs and unsteady gait, which he had experienced 1 month. He has a history of neck pain with left upper limb radiation for the last 2 years. Magnetic resonance imaging showed C5-6 severe central canal stenosis with underlying myelomalacia. Computed tomography showed ossification posterior longitudinal ligament and OLF contributing to severe central canal stenosis at the C5-6 level. The patient underwent C4-C6 laminectomy, debulking of OLF, posterior instrumentation, and fusion with autogenous bone graft from C3 to C6. A histological specimen showed osseous tissue within the ligamentum flavum. After surgery the patient's symptoms improved and no recurrence was observed at 4 years after surgery. The symptoms of myelopathy were successfully treated with debulking instead of complete excision of OLF, thus reducing the risk of dural tear or CSF leakage. PMID- 30276071 TI - Delayed Incisional Hernia Following Minimally Invasive Trans-Psoas Lumbar Spine Surgery: Report of a Rare Complication and Management. AB - Background: Lateral lumbar interbody fusion (LLIF) has proved to be a safe tool in the armamentarium of spine surgeons for a variety of lumbar disorders. However, it has some complications related to specific approaches. Incisional hernia following abdominal surgery and anterior spinal surgery is commonly described; however, it is extremely rare following LLIF, with only 1 case reported in short postoperative period. In this report we present the first case of delayed presentation of true incisional hernia following a LLIF procedure and highlight its presentation, mechanism, possible preventive measures, and management. Methods: We report a 57-year-old lady who underwent L3-4 LLIF. She presented with vague pain in a healed scar area that had no swelling until two years postsurgery, when she developed a painful swelling. On examination, it appeared to be a herniation of abdominal contents. Results: She underwent a laparoscopic hernia repair surgery. The muscular layers were found to be intact with an attenuated transversalis fascia layer. The repair was reinforced by polypropylene mesh. There was no recurrence at the 6-month follow-up. Conclusions: Incisional hernia can occur following LLIF months to years following surgery and can have varied presentation. Tight external oblique closure should be performed because the transversalis fascia often cannot be repaired and the quality of a layered closure of the deep obliques is often disappointing. The treating surgeon should be aware of this complication and aggressively surveil for the warning signs, and patients should be counseled about this potential complication. PMID- 30276072 TI - Early Lumbar Nerve Root Deficit After Three Column Osteotomy for Fixed Sagittal Plane Deformities in Adults. AB - Background: Three-column osteotomy is an effective means of correcting fixed sagittal plane deformities. Deformity correction surgeries may be associated with early postoperative neurological deficits often presenting as palsies involving the lumbar roots. The objective was to retrospectively assess a subset of our series of adult deformity correction surgeries and analyze neurological deficits and associated patient and surgical factors. Methods: Hospital records of 17 patients from a single center were examined. Inclusion criterion were adults (>18 years) who underwent a 3-column osteotomy (pedicle subtraction osteotomy) at the lumbar level for fixed sagittal plane deformities including positive sagittal balance, flat back syndrome, and posttraumatic kyphosis. These also included cases with associated degenerative lumbar scoliosis. Patients were divided in 2 groups: Group 1 with lumbar root deficit and Group 2 with no deficits. We examined the surgical details of the osteotomy, complications during surgery, and observed if the magnitude of correction in the sagittal or coronal plane bore any influence on the nerve deficit. Results: All 17 patients had a single-level resection except 1 patient who had 2-level osteotomy; 23.5% (4 of 17) developed nerve deficit. Nerve deficit presented as bilateral foot drop (1); unilateral extensor hallucis longus (EHL) weakness (2); and unilateral quadriceps weakness (1). The patient with quadriceps weakness partially recovered to functional strength. Two patients with EHL weakness fully recovered; however, the patient with bilateral foot drop did not improve. L5-S1 interbody fusion was done in 3 of 4 cases in Group 1 and 4 of 13 cases in Group 2. Conclusions: Nerve deficits after 3-column corrective osteotomies occurred in 23% cases. All but 1 case had significant improvement. Most nerve palsies are neuropraxia and unilateral and tend to recover. L5 weakness appears most common after high lumbar osteotomies. Significant correction of scoliosis at the osteotomy level (>50%) may be a reason for nerve palsy. PMID- 30276073 TI - Factors Affecting Utilization of Steroid Injections in the Treatment of Lumbosacral Degenerative Conditions in the United States. AB - Background: Lumbar degenerative conditions are an extremely common set of diagnoses with a large spectrum of treatment options. Epidural steroid injections (ESI) are widely used but have come under increased scrutiny as we move toward a value-based model of health care. We assessed current utilization of epidural steroid injections, changes in utilization over time, and the influence of payer type and geographic region within the United States on their utilization. In addition, we analyzed the relationship between ESIs and surgical rates across states. Methods: The Medicare 5% national sample administrative database (SAF5) and a large national database from a commercial health care company (HORTHO) were used to catalog clinical data for patients with lumbar degenerative conditions. Specific queries into the rate of ESIs and lumbar surgery were also performed within this group. Results: There were 4 108 121 patients found between 2005 and 2015 in the SAF5 and HORTHO databases carrying a diagnosis related to lumbar degenerative conditions. The overall yearly injection rates for patients with lumbar degenerative conditions ranged from 9.84% to 10.18%. In patients older than 65, the rate of ESI was higher for Medicare as compared with private payer insurance (16.27% versus 14.14%, P < .001). There was a higher rate of ESI for patients who eventually underwent surgery in the Medicare group as compared with the commercial group (55.30% versus 40.40%, P < .001). There was a positive correlation between rates of ESI with the rate of surgery between states. Conclusions: There is considerable variation in treatment of lumbar degenerative conditions with ESI based on payer type. There was increased utilization of lumbar ESI between 2007 and 2012, although this change was less than 0.5%. The data also suggest a positive correlation between rates of ESIs and surgical intervention across states. This points to areas in the country with high utilization of both ESI and surgery in the treatment of lumbar degenerative conditions. Level of Evidence: III, economic and decision analysis. PMID- 30276074 TI - Clinical Outcomes of Single-Level Anterior Cervical Discectomy and Fusion. AB - Background: The purpose of the present study was to determine the differences in health outcomes between patients with cervical spondylosis who underwent single level anterior cervical discectomy and fusion (ACDF) and patients with cervical spondylosis who did not undergo an ACDF fusion (non-ACDF). The hypothesis of the study was that patients undergoing single-level fusion have a lower risk of downstream cardiovascular disease and depression. Methods: The Medicare 5% sample was used to identify patients who received a diagnosis of spondylosis during 2005 2012. All spondylosis patients were separated into nonoperative and operative groups. Differences in new disease diagnoses, age, sex, and Charlson Comorbidity Index (CCI) scores were recorded. Results: The relative risk (RR) of heart failure was lower in the ACDF group after 3 years (RR = 0.6719; P < .05), 5 years (RR = 0.8477; P = 1.17), and 7 years (RR = 0.7709; P = 1.625). The RR of depression was higher in the ACDF group at 1 year (RR = 2.5008), 3 years (RR = 1.4473), 5 years (RR = 2.2625), and 7 years (RR = 2.2257; P < .05 for all). Mean CCI score of patients before undergoing ACDF was 10 (SD, 9.20), whereas the mean score after surgery was 8 (SD, 7.84; P < .05), and the score for non-ACDF patients remained unchanged at a CCI of 10 (SD, 9.00; P < .05). Conclusions: The results demonstrate the patients in the ACDF cohort have an increased RR of depression but a decreased risk of cardiovascular disease. Further research may be needed to delineate why the ACDF procedure potentially benefits a patient for heart disease but may stress a patient's social/economic supports during the recovery process, thus leading to higher depression rates for patients undergoing ACDF. PMID- 30276075 TI - The Use of Magnetic Resonance Imaging and Plain Radiographs Among Adolescents With Back Pain and Adolescent Idiopathic Scoliosis. AB - Background: Low back pain (LBP) and adolescent idiopathic scoliosis (AIS) are common pediatric diagnoses. The workup for these diagnoses can be highly variable and can use significant health care resources. There has been no analysis to date on the use of imaging for workup of AIS and/or LBP. Methods: The Humana Private Payer Database was queried for clinical and financial information for patients with AIS and/or LBP using International Classification of Diseases (ICD-9) for LBP and AIS. Current procedural terminology codes related to magnetic resonance imaging (MRI) and radiographs for the thoracolumbar spine were used to identify patients with LBP and/or AIS that used these diagnostic imaging modalities. Only patients ages 10 to 19 years were included in this analysis. Results: The total number of patients with AIS and LBP was 18 696 and 56 560, respectively. Thoracolumbar imaging was used within the workup for 71.76% and 45.53% of patients with AIS alone and LBP alone, respectively. MRI was used for 2.92% and 9.53% of patients with AIS alone and LBP alone, respectively. Radiographic imaging was used for 71.06% and 42.63% for AIS alone and LBP alone, respectively. There was minimal variation among regions in use of MRI for AIS. For patients with LBP, the diagnosis with the highest use of MRI was "sciatica" (29.07%). Patients with both LBP and AIS had statistically higher rates of imaging (91.04%), MRI (18.99%), and radiographs (89.71%). Among patients with an MRI, 20.87% never had a radiograph. Reimbursement per patient for radiographs was $164 and $239 for AIS and LBP, respectively. Reimbursement per patient for MRI was $1,263 and $1,882 for AIS and LBP, respectively. Conclusions: There is substantial use of both MRI and radiographs for adolescents with LBP and/or AIS. Clinicians should be aware of the impact these diagnostic tests have on the patient and the overall health care system. PMID- 30276076 TI - Middle-Column Gap Balancing and Middle-Column Mismatch in Spinal Reconstructive Surgery. AB - Background: Middle-column gap balancing (MCGB) is a reference measurement of the path of the posterior longitudinal ligament (PLL), which is reconstructed under tension and balanced by the combined height of the posterior one-third of the vertebral bodies and the posterior one-third of the disks, including any intervening load-sharing spacers. This measurement allows for a comparison of the ligamentous component of the middle column (PLL) with the load-sharing components (posterior one-third vertebral body + disk ). This difference gives rise to a "middle-column mismatch," which provides a linear measurement of the redundancy of the ligaments and neural elements, which relates to the correct cage, spacer, or load-bearing height, which is optimized. Methods: For phase 1 measurement testing, 24 consecutive patients underwent reliable flexion, extension, and neutral lateral radiographic studies with a calibrated marker. The anterior, middle, and posterior columns were measured using a custom software program capable of measuring the length of curved lines specifically written for this purpose. For phase 2 measurement testing, 21 consecutive patients undergoing surgery with multilevel deformities for cervical, thoracic, and lumbar procedures had MCGB height pre- and postoperatively measured by 3 blinded observers. The preoperative and postoperative measurements were compared using a linear regression analysis and Pearson product-moment correlation. Results: In phase 1 measurement testing the flexion, extension, and neutral bending radiographs of spinal segments not containing deformities showed that the middle column had the most reliable measurements of spinal axial height both in the actual measurements of change from flexion to extension (mm) and in percentage of change. In phase 2 measurement testing, a Pearson product-moment correlation was run between each individual's pre- and postoperative middle-column measurements. There was a strong positive correlation between preoperative and postoperative measurements, which was statistically significant (r = 0.983, n = 21, P < .01). Conclusions: This consecutive series of 21 deformity patients demonstrated the utility of measuring the preoperative middle-column length in predicting the optimal height of the spacers and intervertebral disks, and posterior vertebral body height, simultaneously restoring sagittal and coronal plane alignment. Key points of this study include the following: (1) Spinal balance requires optimizing spinal height, which is a curved line in order to accommodate cervical lordosis, thoracic kyphosis, and lumbar lordosis. (2) Software programs can allow measurement of the preoperative curved circuitous course of the PLL and vertebral body misalignment; this curved length is predictive of the optimal postoperative middle-column height after spinal osteotomies and intervertebral spacer insertion. (3) All 3 dimensions are important to optimize in deformity correction: sagittal plane, coronal plane, and axial spinal height. PMID- 30276078 TI - Lumbar Lordosis Correction With Interbody Hyperlordotic Cages: Initial Experience, Learning Curve, Technical Aspects, and Complication Incidence. AB - Background: Analysis of the initial experience on learning curve, technical differences and perioperative or early postoperative complications using lumbar hyperlordotic anterior and lateral interbody cages for the correction of lumbar lordosis as compared with the usage of regular lordotic cages. Methods: Initial 21 consecutive patients were treated with 13 hyperlordotic anterior lumbar interbody fusion (ALIF) cages and 8 hyperlordotic extreme lateral interbody fusion (XLIF) cages. The mean patient age was 64 years, and the mean lumbar hypolordosis was 23 degrees . Results: No significant procedure-related technical differences were found between the hyperlordotic and nonhyperlordotic ALIF cages. Slightly significant procedure-related technical differences were found between hyperlordotic and nonhyperlordotic XLIF cages. The complication type and occurrence were comparable. Conclusions: Sagittal balance correction of lumbar lordosis using hyperlordotic ALIF and XLIF cages is a relatively safe surgical procedure with a short learning curve for those surgeons already familiar with anterior and lateral retroperitoneal procedures. PMID- 30276077 TI - Anterior and Lateral Lumbar Interbody Fusion With Supplemental Interspinous Process Fixation: Outcomes from a Multicenter, Prospective, Randomized, Controlled Study. AB - Background: Rigid interspinous process fixation (ISPF) has received consideration as an efficient, minimally disruptive technique in supporting lumbar interbody fusion. However, despite advantageous intraoperative utility, limited evidence exists characterizing midterm to long-term clinical outcomes with ISPF. The objective of this multicenter study was to prospectively assess patients receiving single-level anterior (ALIF) or lateral (LLIF) lumbar interbody fusion with adjunctive ISPF. Methods: This was a prospective, randomized, multicenter (11 investigators), noninferiority trial. All patients received single-level ALIF or LLIF with supplemental ISPF (n = 66) or pedicle screw fixation (PSF; n = 37) for degenerative disc disease and/or spondylolisthesis (grade <=2). The randomization patient ratio was 2:1, ISPF/PSF. Perioperative and follow-up outcomes were collected (6 weeks, 3 months, 6 months, and 12 months). Results: For ISPF patients, mean posterior intraoperative outcomes were: blood loss, 70.9 mL; operating time, 52.2 minutes; incision length, 5.5 cm; and fluoroscopic imaging time, 10.4 seconds. Statistically significant improvement in patient Oswestry Disability Index scores were achieved by just 6 weeks after operation (P < .01) and improved out to 12 months for the ISPF cohort. Patient-reported 36 Item Short Form Health Survey and Zurich Claudication Questionnaire scores were also significantly improved from baseline to 12 months in the ISPF cohort (P < .01). A total of 92.7% of ISPF patients exhibited interspinous fusion at 12 months. One ISPF patient (1.5%) required a secondary surgical intervention of possible relation to the posterior instrumentation/procedure. Conclusion: ISPF can be achieved quickly, with minimal tissue disruption and complication. In supplementing ALIF and LLIF, ISPF supported significant improvement in early postoperative (<=12 months) patient-reported outcomes, while facilitating robust posterior fusion. PMID- 30276079 TI - Polyetheretherketone (PEEK) Rods for Lumbar Fusion: A Systematic Review and Meta Analysis. AB - Background: The purpose of this systematic review is to evaluate the safety and effectiveness of polyetheretherketone (PEEK) rod systems in patients receiving lumbar interbody fusion treatment. Meta-analyses of relevant clinical data were also conducted when possible. Methods: Relevant studies were identified by searching the PubMed, EMBASE, and Cochrane Library databases. Clinical studies evaluating the safety and/or effectiveness of the PEEK rod spinal stabilization system in patients receiving lumbar spinal fusion procedure were included. Studies regarding dynamic stabilization and hybrid stabilization (fixed and dynamic; eg, topping-off technique) were not included in this analysis. The analyses included patients who had a lumbar fusion procedure with PEEK rods or titanium rods as a control reference (only for controlled studies). Fusion success, functional and pain improvement, and safety data were evaluated, if reported. Results: The search yielded 5 studies (1 prospective and 4 retrospectives) that included 177 participants (156 received PEEK rods, and 21 received titanium rods). Meta-analysis of interbody fusion success rate in PEEK rod patients yields the estimate of 95.6% (confidence interval: 91.6% to 98.4%). Functional outcomes in PEEK rod patients demonstrated clinically significant improvement when comparing postoperative to preoperative scores, with an average improvement of 67.4% +/- 8.5%. Similarly, pain improvement was clinically significant with an average visual analog scores-back pain and visual analog scores-leg pain improvement percentages of 68.9% +/- 8.6% and 76.6% +/- 1.5%, respectively. Rod fracture was not reported in any of the studies. The rates of screw fracture and loosening were 3/114 (2.6%) and 1/50 (2.0%), respectively. In the controlled study, no statistically significant difference was reported in the fusion success rate, function improvement, pain improvement, or device-related events between subjects treated with PEEK rods and the subjects treated with titanium rods. Conclusions: Experience with PEEK rod systems has shown satisfactory clinical outcomes. Therefore, these results support the use of PEEK rod systems as supplemental fixation during lumbar fusion procedures. PMID- 30276081 TI - Feasibility of Endoscopic Inspection of Pedicle Wall Integrity in a Live Surgery Model. AB - Background: Perforations of the pedicle wall during cannulation can occur with experienced surgeons. Direct endoscopic visualization has not been used to inspect pedicles previously due to bone bleeding obscuring the camera visualization. The hypothesis of this study was that endoscopic visualization of pedicle wall integrity was technically feasible and would enable identification of clinically significant pedicle breaches. Methods: A live porcine model was used. Eight lumbar pedicles were cannulated. Clinically significant breaches were created. An endoscope was introduced and was used to inspect the pedicles. Results: All lumbar pedicles were endoscopically visible at a systolic pressure of 100 mm Hg. Clinically relevant anatomic structures and iatrogenic pathology, such as medial, lateral, and anterior breaches, were identified. There were no untoward events resulting from endoscopic inspection of the pedicle endosteal canal. Conclusions: Endoscopic inspection of lumbar pedicles was safe and effective. The findings on endoscopic inspection corresponded with the ball-tip probe palpation techniques. Additional techniques, such as selection between 2 tracts, was possible with the endoscopic technique. PMID- 30276082 TI - Trends in Nonoperative Treatment Modalities Prior to Cervical Surgery and Impact on Patient-Derived Outcomes: Two-Year Analysis of 1522 Patients From the Prospective Spine Treatment Outcome Study. AB - Background: Effects of nonoperative treatments on surgical outcomes for patients who failed conservative management for cervical spine pathologies remain unknown. The objective is to describe conservative modality use in patients indicated for surgery for degenerative cervical spine conditions and its impact on perioperative outcomes. Methods: The current study comprises a retrospective review of a prospective multicenter database. A total of 1522 patients with 1- to 2-level degenerative cervical pathology who were undergoing surgical intervention were included. Outcome measures used were health-related quality-of-life scores, length of hospitalization, estimated blood loss, length of surgery, and return-to work status at 2 weeks, 6 months, 1 year, and 2 years postoperatively. Patients were grouped by diagnosis (radiculopathy vs. myelopathy), then divided based on epidural injection(s), physical therapy (PT), or opioid use prior to enrollment. Univariate t-tests and chi2 tests were performed to determine differences between groups and impact on outcomes. Results: Among 1319 radiculopathy patients, 25.7% received preoperative epidural injections, 35.3% received PT, and 35.5% received opioids. Radiculopathy patients who received epidurals and PT had higher 1-year postoperative return-to-work rates (P < .05). Radiculopathy patients without preoperative PT had longer hospitalization times, whereas those who received PT had higher 36-Item Short Form Health Survey (SF-36) physical functioning and physical component scores, lower 2-year visual analog scale (VAS) neck/arm pain scores, and higher 2-year return-to-work incidence (P < .05). Of myelopathy patients (n = 203), 14.8% received epidural injections, 25.1% received opioids, and 41.5% received PT. Myelopathy patients with preoperative PT had worse VAS arm pain scores 2 years postoperatively (P < .05). Patients receiving opioids were younger and had greater baseline-2-year Neck Disability Index improvement (P < .05). Conclusions: Radiculopathy patients receiving epidurals returned to work after 1 year more frequently. PT was associated with shorter hospitalizations, greater SF-36 bodily pain norm and physical component score improvements, and increased return-to-work rates after 1 and 2 years. No statistically significant nonoperative treatment was associated with return-to-work rate in myelopathy patients. Clinical Relevance: These findings suggest certain preoperative conservative treatment modalities are associated with improved outcomes in radiculopathy patients. PMID- 30276083 TI - Risk of Cancer Following Lumbar Fusion Surgery With Recombinant Human Bone Morphogenic Protein-2 (rhBMP-2): An Analysis Using a Commercially Insured Patient Population. AB - Background: Recombinant human bone morphogenetic protein-2 (rhBMP-2) is frequently used to promote new bone growth after lumbar fusion surgery. However, because BMP receptors are found on cancer cells, there is concern about potential cancer following treatment with rhBMP-2. Data from clinical trials have reported divergent results and have been limited by small sample sizes and relatively short follow-up. We therefore examined the long-term risk of cancer following treatment with rhBMP-2 after lumbar fusion surgery. Methods: Using the MarketScan Commercial Claims and Encounters database, we identified all patients <65 years without prior cancer who underwent lumbar fusion surgery between October 2003 and December 2009 and were followed at least 3 years after surgery. Development of any Surveillance Epidemiology and End Results malignancy in follow-up was identified through diagnosis and procedure codes. Results: Among 39 448 eligible patients, 2345 (5.9%) received rhBMP at surgery; the median follow-up in this population was 4.87 years. Cancer in follow-up was observed in 49 BMP-treated patients (0.43/100 person years) and 1072 nontreated patients (0.58/100 person years). Use of rhBMP was associated with a cancer risk similar to that of untreated patients in both univariate (hazard ratio, 0.80; 95%, CI 0.54-1.19) and multivariate proportional hazards analyses (hazard ratio, 0.81; 95% CI, 0.54 1.20). Similar findings were observed in a secondary analysis after adjustment for likelihood of rhBMP administration. Conclusions: In this retrospective cohort with at least 3 years of follow-up, administration of rhBMP during lumbar fusion surgery was not associated with an increased risk of subsequent cancer.

AB - Study Design: Retrospective radiographic study. Purpose: Predict the variability of the center of gravity of head (COG) relative to the global cervical sagittal alignment (SVA). Background: Cervical lordosis, thoracic kyphosis, lumbar lordosis, and pelvic incidence are considered interrelated, with changes in SVA causing reciprocal changes to bring the head over pelvis. The implications of cervical deformities have generated more interest recently, and it has been shown that poor cervical alignment is associated with poor clinical outcomes. Methods: Patients were selected from the imaging server of a single institution with adult spinal deformity (ASD) and SVA, who underwent surgical correction from 2008 to 2013. Three observers performed the measurements, and intraclass correlation coefficient (ICC) was measured for inter and intraobserver reliability. Group 1 was patients with unbalanced spines (C7-SVA > 5 cm) preoperatively and corrected to full balanced spine (C7-SVA < 5 cm) until last follow-up. Group 2 was improved in sagittal balance after surgery and maintained SVA correction until last follow up, but not fully balanced. Results: Fifty-five patients met the inclusion criteria, 42 patients improved in SVA after surgery, and 13 showed no improvement. Twenty-three patients kept full balanced measurements until last follow-up, and 19 patients maintained not-full balanced spine. In group 1, there was no change in pre and postoperative parameters except for C2-CL (21.74 degrees vs 16.91 degrees , P = .033). It was similar in group 2, no differences except for C2-CL (21.67 degrees vs 17.81 degrees , P = .018). Conclusion: Parameters in this study failed to yield predictable relationships when compared to changes in SVA. The position of COG may be independent of global SVA. Clinical Relevance: This study aims to improve our understanding of the dynamic changes and relationships of the regional and global spinal parameters with regard to spinal deformity corrective surgeries in adults.

PMID- 30276085 TI - Rates of Mortality in Cervical Spine Surgical Procedures and Factors Associated With Its Occurrence Over a 10-Year Period: A Study of 342 477 Patients on the Nationwide Inpatient Sample. AB - Background: Risk of death is important in counseling patients and improving quality of care. Incidence of death in cervical surgery is not firmly established due to its rarity and limited sample sizes, particularly in the context of different surgeries, demographics, and risk factors. Particularly, different patient risk profiles may have varying degrees of risk in terms of surgeries, comorbidities, and demographics. This study aims to use a large patient cohort available on a national database to study the prevalence of death associated with cervical spine surgery. Methods: This study was a retrospective review of the Nationwide Inpatient Sample (NIS) years 2003-2012. A total of 342 477 patients were identified by International Classification of Diseases, Ninth Revision, Clinical Modification codes undergoing spinal fusion or decompression for disc degeneration, stenosis, spondylosis, myelopathy, postlaminectomy syndrome, scoliosis, or neck pain associated with the cervical region. Patients with malignancy were excluded from analysis. Incidence of mortality was assessed by chi2 tests across different patient demographics and comorbidities, procedures performed, and concurrent in-hospital complications. Binary logistic regression identified significant increases or decreases in risk of death while controlling for comorbidities, race, sex, and Mirza invasiveness. Significance was defined as P < .05 differences relative to overall cohort. Results: The study analyzed 342 477 patients with an overall mortality rate of 0.32%. A total of 231 977 simple fusions (single approach and <3 levels) experienced a mortality rate of 0.256%; 49 594 complex fusions (combined approach or >=3 levels) had a mortality rate of 0.534%; and 61 285 decompression-only procedures reported a 0.424% mortality rate, all P < .001 from overall rate. In reporting rates across different demographics, male patients experienced a significantly higher risk for mortality (odds ratio [OR], 2.16; 95% CI, 1.87-4.49), as did black patients (OR, 1.58; CI, 1.32-1.90) and patients over age 75 (OR, 7.55; 95% CI, 6.58-8.65), all P < .001. Patients with liver disease reported 6.40% mortality. Similarly, patients with congestive heart failure (3.91%), cerebrovascular disease (3.41%), and paraplegia (3.79%) experienced high mortality rates, all in cohorts of over 2000 patients, all P < .001. Concurrent in-hospital complications with the highest risk of mortality were shock (OR, 51.41; 95% CI, 24.08-109.76), pulmonary embolism (OR, 25.01; 95% CI, 14.70-42.56), and adult respiratory distress disorder (OR, 14.94; 95% CI, 12.75-17.52), all P < .001. Conclusion: In 342 477 cervical spine surgery patients an overall mortality rate of 0.32% was reported. The rate was 3.91% in a cohort of 5933 patients with congestive heart failure and 3.79% in a cohort of 6947 patients with paraplegia. These findings are consistent with previous estimates and may help counsel patients and improve in-hospital safety. Level of Evidence: 3. PMID- 30276086 TI - Does Resection of the Posterior Longitudinal Ligament Affect the Stability of Cervical Disc Arthroplasty? AB - Background: The need for posterior longitudinal ligament (PLL) resection during cervical total disc arthroplasty (TDA) has been debated. The purpose of this laboratory study was to investigate the effect of PLL resection on cervical kinematics after TDA. Methods: Eight cadaveric cervical spine specimens were tested in flexion-extension (FE), lateral bending (LB), and axial rotation (AR) to moments of +/-1.5 Nm. After testing the intact condition, anterior C5-C6 cervical discectomy was performed followed by PLL resection and implantation of a compressible, 6-degrees-of-freedom disc prosthesis (M6-C, Spinal Kinetics Inc, Sunnyvale, California). Next, a second prosthesis was implanted at C6-C7 with PLL intact. Finally, the C6-C7 PLL was resected while the disc prosthesis remained in place. Segmental range of motion (ROM) and stiffness in the high flexibility zone around the neutral posture were analyzed using repeated measures ANOVA. Results: At C5-C6, following TDA and PLL resection, FE, LB, and AR ROMs decreased significantly. Anterior and posterior disc height, segmental lordosis, and flexion stiffness increased significantly. At C6-C7, TDA with the PLL intact resulted in a significant increase in anterior disc height and segmental lordosis with no change in posterior disc height. FE, LB, and AR ROMs all decreased significantly, while flexion stiffness increased significantly compared to intact. PLL resection at C6-C7 did not result in a notable change compared to TDA with PLL intact. At the same level, flexion stiffness decreased following PLL resection compared to TDA with a value closer to intact. Two-level TDA (C5-C7) with PLL resection did not result in a loss of segmental stability. Conclusion: PLL resection did not significantly affect motion segment kinematics following cervical TDA using a prosthesis with inherent stiffness. Motion segment stiffness loss after PLL resection can be compensated for by a TDA design that can provide resistance to angular motion. PMID- 30276087 TI - Review of Vertebral Augmentation: An Updated Meta-analysis of the Effectiveness. AB - Background: To update vertebral augmentation literature by comparing outcomes between vertebroplasty (VP), balloon kyphoplasty (BKP), vertebral augmentation with implant (VAI), and nonsurgical management (NSM) for treating vertebral compression fractures (VCFs). Methods: A PubMed literature search was conducted with keywords kyphoplasty, vertebroplasty, vertebral body stent, and vertebral augmentation AND implant for English-language articles from February 1, 2011, to November 22, 2016. Among the results, 25 met the inclusion criteria for the meta analysis. Inclusion criteria were prospective comparative studies for mid-/lower thoracic and lumbar VCFs enrolling at least 20 patients. Exclusion criteria included studies that were single arm, systematic reviews and meta-analyses, traumatic nonosteoporotic or cancer-related fractures, lack of clinical outcomes, or non-Level I and non-Level II studies. Standardized mean difference between baseline and end point for each outcome was calculated, and treatment groups were pooled using random effects meta-analysis. Results: Visual analog scale pain reduction for BKP and VP was -4.05 and -3.88, respectively. VP was better than but not significantly different from NSM (-2.66), yet BKP showed significant improvement from both NSM and VAI (-2.77). The Oswestry Disability Index reduction for BKP showed a significant improvement over VAI (P < .001). There was no significant difference in changes between BKP and VP for anterior (P = .226) and posterior (P = .293) vertebral height restoration. There was no significant difference in subsequent fractures following BKP (32.7%; 95% confidence interval [CI]: 8.8%-56.6%) or VP (28.3%; 95% CI: 7.0%-49.7%) compared with NSM (15.9%; 95% CI: 5.2%-26.6%). Conclusions/Level of Evidence: Based on Level I and II studies, BKP had significantly better and VP tended to have better pain reduction compared with NSM. BKP tended to have better height restoration than VP. Additionally, BKP had significant improvements in pain reduction and disability score as compared with VAI. Clinical Relevance: This meta-analysis serves to further define and support the safety and efficacy of vertebral augmentation. PMID- 30276088 TI - Anterior Lumbar Interbody Fusion With Cement Augmentation Without Posterior Fixation to Treat Isthmic Spondylolisthesis in an Osteopenic Patient-A Surgical Technique. AB - Background: Anterior lumbar interbody fusion (ALIF) has been well established as an effective surgical intervention for chronic back pain due to osteoporotic vertebral collapse. Historically, ALIF has consisted of an anterior approach to disc height restoration with a subsequent posterior pedicle screw fixation. Although the applications of cement augmentation with posterior fixation have been previously reported, treatment of patients with both isthmic spondylolisthesis and decreased bone mineral density using a stand-alone ALIF is controversial because of concerns for decreased fusion rates and increased subsidence risk, respectively. We report a case of stand-alone ALIF used to treat a low-grade isthmic spondylolisthesis in the setting of idiopathic thoraco-lumbar scoliosis in a patient with secondary degenerative changes and discuss the benefits of this surgical technique in a patient with several comorbidities. Methods: An osteopenic 66-year-old woman with multiple medical comorbidities and 2 years of left radicular leg pain was found to have a Myerding grade I isthmic spondylolisthesis in the setting of idiopathic thoraco-lumbar scoliosis with secondary changes. The patient underwent an L5-S1 stand-alone ALIF with anterior cement augmentation without posterior pedicle screw fixation. Results: The patient experienced immediate relief of radicular leg pain postoperatively and had an uneventful course. At 2 years follow-up, she remained symptom free, and radiographs showed excellent fusion and maintenance of intervertebral disc height. Conclusions: The use of stand-alone ALIF with anterior cement augmentation of the vertebral bodies is a surgical technique that could produce excellent improvement in patients with low-grade isthmic spondylolisthesis in the setting of osteopenia. The use of the all-anterior approach in similar patients with multiple medical comorbidities can also be a useful technique, as it decreases associated morbidity of surgery and complication risks associated with prolonged operative times. PMID- 30276089 TI - Combined Aorto-Iliac and Anterior Lumbar Spine Reconstruction: A Case Series. AB - Background: Treatment options for aortic-iliac pathology may include endovascular repair and open surgical repair. Treatment options for degenerative disc disease (DDD) are varied but commonly include anterior reconstruction. When both the aortic-iliac and spinal pathologies are significant and surgical intervention is indicated for each pathology, the opportunity exists for concurrent treatment of both the aortic-iliac pathology and DDD in the same operation. The purpose of this case series was to document the safety and feasibility of a surgical strategy whereby a combined elective reconstructive procedure was performed for aortic and anterior lumbar spinal pathologies. Methods: The case histories of 5 patients who were treated for both spinal and vascular pathology are presented. Surgical outcome measures included operative time, blood loss, length of stay, and complications. Spine-specific outcome measures included Oswestry Disability Index, Roland Morris Disability Questionnaire, and visual analogue scores (back and leg). Results: The spinal reconstructions performed included 1 L4-5 total disc replacement (TDR), 1 L4-5, L5-S1 anterior lumbar interbody fusion (ALIF), 1 L5-S1 ALIF, and 2 hybrid procedures (L4-5 TDR with L5-S1 ALIF). Vascular reconstructions included 4 aorto-bi-iliac bypass grafts and 1 aortic tube graft. The average operative time was 365 minutes (ranging between 330 and 510 minutes), the average blood loss was 1699 mL (range between 1160 and 2960 mL), and the average length of hospital stay was 14 days (range from 8 to 22 days). There were no in-hospital complications, and all patients experienced significant improvement in both back and leg pain. One patient developed kinking of the iliac limbs of the vascular graft 1 year postoperatively, which was managed with endovascular stenting of the graft. Conclusions: Aortic-iliac pathology and DDD are significant pathologies often treated in isolation. This study illustrates that, despite its complexity, highly trained individuals in a specialized setting can perform combined surgery to achieve a satisfactory outcome for the patient. Level of Evidence: Level IV evidence. PMID- 30276090 TI - Ligamentum Flavum Hematoma Presented with Low Back Pain: A Case Report and Review of the Literature. AB - A 61-year-old woman with no past medical history presented with low back pain and radicular pain in the right lower extremity. Magnetic resonance imaging of the lumbar spine showed a heterogeneous intensity mass in the lateral recess of the spinal canal at the L4-5 disk level. Postoperatively, her radicular pain resolved within a few days with excellent low back pain relief. Ligamentum flavum hematoma is a rare differential diagnosis for cystic lesions in the lumbar spine that can be removed simply by surgery with excellent relief of symptoms and improvement in strength of the right lower extremity and increased sensitivity. PMID- 30276091 TI - Readmissions After Outpatient Transforaminal Decompression for Lumbar Foraminal and Lateral Recess Stenosis. AB - Background: The objective of this study was to analyze readmission rates after outpatient transforaminal endoscopic decompression surgery for lumbar foraminal and lateral recess stenosis done in an ambulatory surgery center. Endoscopic lumbar spinal surgery is gaining popularity for the treatment of lumbar disc herniations. Recent advances in surgical techniques allow for percutaneous endoscopically assisted bony decompression for neurogenic claudication symptoms due to spinal stenosis. The surgery can be done under local anesthesia and sedation. Patients may be discharged home within hours from surgery, and complications are rare. However, readmissions for recurrent disc herniations, failure of pain relief, dysesthetic leg pain, nerve root injuries with foot drop, and facet and pedicle fractures have been reported. Methods: A retrospective study of 1839 consecutive patients with an average mean follow up of 33 months (range 24 to 85 months) that underwent percutaneous endoscopic surgery at 2076 levels between 2006 and 2015 was conducted with the intent of identifying factors associated with emergency room or hospital readmission following endoscopic foraminotomy and microdiscectomy. Only patients with unilateral radiculopathy due to either herniated disc or lateral recess stenosis were included in this study. Preoperatively, disc migration was graded by direction and distance from the disc space according to Lee's radiologic 4-zone classification. The type of disc herniation was classified either as extruded or contained. Contained herniations were further subclassified as disc protrusions versus disc bulges. In addition, the preoperative disc height was recorded. Bony spinal foraminal stenosis and lateral recess stenosis were graded on preoperative magnetic resonance imaging and computed tomography scans into mild, moderate, and severe by dividing the lumbar neuroforamen into 3 zones: (a) entry zone, (b) midzone, and (c) exit zone. Surgical outcomes were classified according to the Macnab criteria. In addition, reduction in visual analog scores (VASs) were assessed. The treating physician (KUL) performed all surgeries. Results: According to the Macnab criteria, excellent and good results were obtained in 82.2% of patients with extruded disc fragment (331/1839). In this group, the mean VAS decreased from 5.9 +/- 2.5 preoperatively to 2.4 +/- 1.8 at the final follow up (P < .01). Patients with contained disc herniations (648/1839) had excellent and good results 72.7% of the time. In this group, the mean VAS decreased from 7.2 +/- 1.6 preoperatively to 3.1 +/- 1.5 at the final follow up (P < .01). In the spinal stenosis group (860/1839), 75% of patients had excellent to good results. There were no major approach-related complications. Sixty-nine patients had extravasations of irrigation fluid into the subcutaneous tissues (3.8%). Eight patients developed spinal headaches (0.4%). Two patients developed foot drop on the surgical side immediately postoperatively (0.1%). Reherniations of extruded discs occurred in 9 patients (2.7% recurrence rate). Failure of pain relief without significant improvement of walking endurance occurred in 29 patients with bony stenosis in the central canal, lateral recess, and entry zone of the neuroforamen (3.3%). Reherniations were associated with preserved disc height of >6 mm (P < .02). Dysesthetic leg pain due to dorsal root ganglion irritation occurred in 229 patients (12.4%) and was unrelated to case frequency but was associated with severe foraminal stenosis (P < .01). All 229 patients improved with supportive care. Facet or pedicle fractures did not occur in this series. There were 26 acute care (within 6 weeks from surgery) postoperative emergency room visits [16 of which resulted in readmission to a hospital over the 9-year study period (0.86%): 9 for dysesthetic leg pain, 2 for wound infections, and 5 for poorly controlled incisional pain]. Conclusions: Transforaminal endoscopic decompression can be successfully carried out in an outpatient surgery center setting. Readmissions due to reherniations, postoperative complications, or poor pain control are uncommon. PMID- 30276092 TI - Heterotopic Ossification After Cervical Total Disc Replacement at 7 Years Prevalence, Progression, Clinical Implications, and Risk Factors. AB - Background: Heterotopic ossification (HO) is a known risk following cervical total disc replacement (CTDR) surgery, but the cause and effect of HO are not well understood. Reported HO rates vary, and few studies are specifically designed to report HO. The effects on outcomes, and the risk factors for the development of HO have been hypothesized and reported in small-population, retrospective analyses, using univariate statistics. Methods: Posthoc, multiple phase analysis of radiographic, clinical, and demographic data for CTDR as it relates to HO was performed. HO was radiographically graded for 164 one-level and 225 two-level CTDR patients using the McAfee and Mehren system. Analysis was performed to correlate HO grades to clinical outcomes and to evaluate potential risk factors for the development of HO using demographics and baseline clinical measures. Results: At 7 years, 1-level clinically relevant HO grades were 17.6% grade 3 and 11.1% grade 4. Two-level clinically relevant HO grades, evaluated using the highest patient grade, were 26.6% grade 3 and 10.8% grade 4. Interaction between HO and time revealed significance for neck disability index (NDI; P = .04) and Visual Analog Scale (VAS) neck pain (P = .02). When analyzed at each time point NDI was significant at 48-84 months and VAS neck at 60 months. For predictors 2 analyses were run; odds ratios indicated follow-up visit, male sex, and preoperative VAS neck pain are related to HO development, whereas hazard ratios indicated male sex, obesity, endplate coverage, levels treated, and preoperative VAS neck pain. Conclusions: This is the largest study to report HO rates, and related outcomes and risk factors. To develop an accurate predictive model, further large-scale analyses need to be performed. Based on the results reported here, clinically relevant HO should be more accurately described as motion-restricting HO until a definitive link to outcomes has been established. PMID- 30276093 TI - T1 Slope Minus Cervical Lordosis (TS-CL), the Cervical Answer to PI-LL, Defines Cervical Sagittal Deformity in Patients Undergoing Thoracolumbar Osteotomy. AB - Background: Cervical kyphosis and C2-C7 plumb line (CPL) are established descriptors of cervical sagittal deformity (CSD). Reciprocal changes in these parameters have been demonstrated in thoracolumbar deformity correction. The purpose of this study was to investigate the development of CSD, using T1 slope minus cervical lordosis (TS-CL) to define CSD and to correlate TS-CL and a novel global sagittal parameter, cervical-thoracic pelvic angle (CTPA), with CPL. Methods: A multicenter, retrospective analysis of patients with thoracolumbar deformity undergoing three-column osteotomy was performed. Preoperative and postoperative cervical parameters were investigated. Linear regression for postoperative values resulted in a CPL of 4 cm corresponding to a TS-CL threshold of 17 degrees . Patients were classified based on postoperative TS-CL into uncompensated (TS-CL > 17 degrees ) or compensated cohorts (TS-CL < 17 degrees ); the two were compared using an unpaired t test. Logistic regression modeling was used to determine predictors of postoperative CSD. Results: A total of 223 patients with thoracolumbar deformity (mean age, 57.56 years) were identified. CTPA correlated with CPL (preoperative r = .85, postoperative r = .69). TS-CL correlated with CTPA (preoperative r = .52, postoperative r = .37) and CPL (preoperative r = .52; postoperative r = .37). CSD had greater preoperative CPL (P < .001) and CTPA (P < .001). The compensated cohort had a decrease in TS-CL (from 10.2 to 8.0) with sagittal vertical axis (SVA) correction, whereas the uncompensated had an increase in TS-CL (from 22.3 to 26.8) with all P < .001. Reciprocal change was demonstrated in the compensated group given that CL decreased with SVA correction (r = .39), but there was no such correlation in the uncompensated. Positive predictors of postoperative CSD included baseline TS-CL > 17 degrees (P = .007), longer fusion (P = .033), and baseline CTPA (P = .029). Conclusions: TS-CL and CTPA correlated significantly with established sagittal balance measures. Whereas reciprocal change in cervical and thoracolumbar alignment was demonstrated in the compensated cohort, the uncompensated population had progression of their cervical deformities after three-column osteotomy. Clinical Relevance: The balance between TS-CL mirrors the relationship between pelvic incidence minus lumbar lordosis in defining deformities of their respective spinal regions. PMID- 30276094 TI - Is There an Association With Spino-Pelvic Relationships and Clinical Outcome of Type A Thoracic and Lumbar Fractures Treated Non-Surgically? AB - Background: The objective was to evaluate if there is an association of the spino pelvic relationships and the global spinal alignment with the outcome of AO type A injuries treated nonsurgically. Methods: This is a retrospective case series. Patients treated nonsurgically for AOSpine type A fractures (T1-L5) with at least 1 year follow-up identified. A standing antero-posterior and lateral 36-inch radiographs and measures of spino-pelvic relationships and sagittal alignment were obtained, as well as clinical assessment using the visual analog scale, the Short-Form 36 (SF-36) questionnaire, the Oswestry Disability Index (ODI), and labor status. Results: Twenty-two patients with 33 fractures were included (L1 was the most injured level with 18.2%). There were 17 men (77.2%) and the mean age was 47.1 years. Follow-up ranged from 12 to 60 months (mean of 27.8 months). There were 22 type A1 (66.7%), 3 type A2 (9%), 6 type A3 (18%), and 2 type A4 (6%) fractures. The ODI ranged from 4% to 58%, with a mean of 24.4%. The SF-36 physical health score ranged from 23 to 82.25 (mean 49.59), and the mental health score ranged from 14.75 to 94.25 (mean 63.28). No association was identified between the spino-pelvic measurements, global alignment, and patient-reported outcomes. Conclusions: Type A fractures had a clinically relevant amount of long term disability even when surgical treatment is not required. Spino-pelvic relationships and final global spinal alignment did not associate with outcome measurements. PMID- 30276096 TI - Treatment of Low Back Pain by Treating the Annular High Intensity Zone (HIZ) Lesions Using Percutaneous Transforaminal Endoscopic Disc Surgery. AB - Background: The study design was a retrospective case series. The objective was to find the clinical success rate of percutaneous transforaminal endoscopic disc surgery in patients suffering from discogenic chronic low back pain who were showing high intensity zone (HIZ) with degenerated disc as the only abnormality in the magnetic resonance imaging (MRI). The HIZ in the posterior annulus in degenerated disc is recognized as a pain generator. There are only a few studies available in the literature addressing the effect of identification and treatment of HIZ in the chronic low back pain patient. Methods: We retrospectively evaluated the case records of all the patients who were treated by percutaneous endoscopic disc surgery for relief of symptoms as determined by visual analog scale (VAS) score, Oswestry Disability Index (ODI), Mac Nab criteria, and the consumption of analgesics, who had the predominant symptom of chronic low back pain, and whose lumbar spine MRI showed degenerated disc with HIZ and no other cause of back pain, like facet joint arthritis or sacroiliac joint arthritis. Results: A total of 23 patients were identified to include in the study. Mean preoperative duration of low back pain was 13.1 months. Mean follow up after the procedure was 29 months. At final follow up, 69.6% of the patients were not taking any pain medicines, 17.36% were on frequent analgesic medicines, 13.04% were on occasional analgesics. There was statistically significant reduction in VAS at 6 weeks postop and final follow up after surgery and the ODI at final follow up; 82.6% of patients had an excellent/good outcome as per Mac Nab criteria. There were no complications or reoperations in any of the patients. Conclusions: Visualization and ablation of the chronic annular pathology in HIZ may give an effective and minimally invasive treatment for one of the back pain causes. PMID- 30276095 TI - Long-Term Clinical Experience with Selectively Constrained SECURE-C Cervical Artificial Disc for 1-Level Cervical Disc Disease: Results from Seven-Year Follow Up of a Prospective, Randomized, Controlled Investigational Device Exemption Clinical Trial. AB - Background: This research was initiated to compare the long-term clinical safety and effectiveness of the selectively constrained SECURE-C (Globus Medical, Audubon, Pennsylvania) Cervical Artificial Disc to anterior cervical discectomy and fusion (ACDF). To preserve segmental motion, cervical total disc replacement (CTDR) was developed as an alternative to ACDF. Current CTDR designs incorporate constrained and unconstrained metal-on-metal or metal-on-polymer articulation with various means of fixation. Methods: Eighteen investigational sites participated in this prospective clinical trial; 380 patients were enrolled and treated in the investigational device exemption study. The first 5 patients treated at each site were nonrandomized and received the investigational SECURE-C device. Patients were randomized, treated surgically, and evaluated postoperatively at 6 weeks, 3 months, 6 months, 12 months, 24 months, and annually thereafter through 84 months postoperative. Results: Overall results for the randomized cohorts demonstrated statistical superiority of the investigational SECURE-C group over the control ACDF group at 84 months postoperative. SECURE-C showed clinically significant improvement in pain and function in terms of neck disability index and visual analog scale scores, and superiority in patient satisfaction was also achieved for patients treated with SECURE-C. Conclusion: Clinical study results indicated that the selectively constrained SECURE-C Cervical Artificial Disc is as safe and effective as ACDF. Long-term results from the Post Approval Study demonstrated that SECURE-C is statistically superior to ACDF in terms of overall success and patient satisfaction. Lower rates of subsequent index-level surgeries and device-related adverse events were observed in the SECURE-C group than in the ACDF group. The long-term, level 1 clinical evidence presented here is consistent with other reports supporting the safety and efficacy of cervical arthroplasty, and furthers advocacy for motion preservation as a viable alternative to fusion. PMID- 30276098 TI - Long-Term Experience With Reduction Technique in High-Grade Spondylolisthesis in the Young. AB - Background: Surgical management of high-grade spondylolisthesis in the young is not only challenging but also controversial, from in-situ fusion to complete reduction. It is fraught with dangers such as neurological injury, pseudoarthrosis, and progressive deformity with subsequent global sagittal imbalance. We describe our experience of progressive reduction technique and restoration of lumbosacral alignment. Methods: This study is a retrospective review of patients who underwent surgery between 1998 and 2012. The surgical technique involved positioning the hips in extension with traction, pedicle screw fixation, correction of lumbosacral kyphosis with a specific distraction maneuver, wide decompression, and gradual reduction of the deformity and maintenance of reduction with interbody fusion. All patients were serially assessed at 1, 3, and 6 months and yearly thereafter with clinical, radiological, and Oswestry Disability Index and Visual Analogue Scale outcome measures. Results: Twenty-seven patients with high-grade spondylolisthesis at L5-S1 (3 cases grade 3, 7 grade 4, 17 grade 5) with an average age of 13.9 years were reviewed. Mean follow-up was 120 months (range 24-192). All patients presented a solid fusion at the 6-month visit; mean slip percentage was reduced from 89% to 23%, with all cases reduced to grade 2 or less. The slip angle improved from 45 degrees to 3 degrees postoperatively, with improvement in sacral slope from 13 degrees to 35 degrees . Four spondyloptosis patients had concomitant scoliosis which corrected spontaneously after the surgery and did not need further intervention. All but one patient (96.2%) had good functional outcomes and returned to their full normal activities. One patient developed a deep infection necessitating implant removal, with eventual deformity progression leading to a poor outcome. Three patients (11.1%) suffered partial drop foot that resolved in full by 12 weeks. Conclusion: Our technique demonstrated a significant reduction of high grade spondylolisthesis, with restoration of global sagittal balance via correction of the lumbosacral kyphosis. Though surgically demanding, it is safe and reproducible. Level of Evidence: IV. PMID- 30276097 TI - Demographic Trends in the Use of Intraoperative Neuromonitoring for Scoliosis Surgery in the United States. AB - Background: Intraoperative neuromonitoring (ION), such as motor-evoked potential (MEP), somatosensory evoked potentials (SSEP), and electromyography (EMG), is used to detect impending neurological injuries during spinal surgery. To date, little is known about the trends in the use of ION for scoliosis surgery in the United States. Methods: A retrospective review was performed using the PearlDiver Database to identify patients that had scoliosis surgery with and without ION from years 2005 to 2011. Demographic information (such as age, gender, region within the United States) and clinical information (such as type of ION and rates of neurological injury) were assessed. Results: There were 3618 patients who had scoliosis surgery during the study period. Intraoperative neuromonitoring was used in 1361 (37.6%) of these cases. The number of cases in which ION was used increased from 27% in 2005 to 46.9% in 2011 (P < .0001). Multimodal ION was used more commonly than unimodal ION (64.6% versus 35.4%). The most commonly used modality was combined SSEP and EMG, while the least used modality was MEP only. Neurological injuries occurred in 1.8 and 2.0% of patients that had surgery with and without ION, respectively (P = .561). Intraoperative neuromonitoring was used most commonly in patients <65 years of age and in the Northeastern part of the United States (age P = .006, region P < .0001). Conclusions: The use of ION for scoliosis surgery gradually increased annually from 2005 to 2011. Age and regional differences were noted with neuromonitoring being most commonly used for scoliosis surgery in nonelderly patients and in the Northeastern part of the United States. No differences were noted in the risk of neurological injury in patients that had surgery with and without ION. Although the findings from this study may seem to suggest that ION may not influence the risk of neurologic injury, this result must be interpreted with caution as inherently riskier surgeries may utilize ION more, leading to an actual reduction in injuries more dramatic than observed in this study. PMID- 30276099 TI - Transforaminal Endoscopic Decompression of the Lumbar Spine for Stable Isthmic Spondylolisthesis as the Least Invasive Surgical Treatment Using the YESS Surgery Technique. AB - The first author's series has reported and published his 5- to 10-year results in a preliminary review of endoscopic transforaminal decompression for degenerative and isthmic spondylolisthesis causing sciatica and back pain. This study was initiated due to favorable results in relieving both back and leg pain after a spine surgeon with isthmic spondylolisthesis who wanted to avoid fusion requested consideration for an endoscopic procedure for his own isthmic spondylolisthesis condition. After listening to the first author's podium presentation on selective endoscopic discectomy and foraminal decompression under local anesthesia in 1995, he requested consideration for transforaminal endoscopic decompression for recent onset of progressive sciatica from his isthmic spondylolisthesis. He was the first patient to undergo endoscopic decompression in our series of 55 patients from January 2002 to December 2012 that served as the database for a clinical case series review of selective endoscopic discectomy and foraminoplasty in patients with degenerative spondylolisthesis who specifically chose to stage the author's endoscopic transforaminal decompressive trademarked procedure over fusion. The patients were evaluated and considered for the endoscopic procedure specifically at their request, even though they were informed about the traditional "gold standard" fusion for surgical intervention. At that time the medical field did not have the database to study outcomes other than the favorable clinical results found in patients who underwent selective endoscopic discectomy and foraminoplasty for degenerative spondylolisthesis. These patients were accepted for endoscopic spine surgery in a shared clinical decision after full disclosure. The patients opted specifically for the Yeung Endoscopic Spine Surgery (YESS) technique that included foraminoplasty and dorsal endoscopic rhizotomy from the author's evolving clinical experience of 10,000 cases over 27 years. PMID- 30276100 TI - Symptomatic Vertebral Hemangioma of the Posterior Elements Sharing Blood Supply with a Radiculomedullary Artery. AB - Vertebral hemangiomas are common lesions usually restricted to the vertebral body. They are characterized by proliferation of endothelial cells and subsequent expansion of vascular spaces within the bone. These lesions are usually clinically silent and are discovered incidentally. Only rarely are vertebral hemangiomas symptomatic. Here, we present the case of a 68-year-old female with an aggressive hemangioma causing neurologic deficit. The lesion was localized within the posterior spinal elements, with no involvement of the vertebral body. Transarterial embolization was deemed unsafe due to the close proximity of a prominent radiculomedullary artery. The patient was treated with posterior decompression at T4-T6. PMID- 30276101 TI - The 2-Level Experience of Interlaminar Stabilization: 5-Year Follow-Up of a Prospective, Randomized Clinical Experience Compared to Fusion for the Sustainable Management of Spinal Stenosis. AB - Background: To alleviate the symptoms of lumbar spinal stenosis, widely accepted methods of surgical treatment include decompression alone and decompression with fusion. As an alternative to these methods, interlaminar stabilization (ILS) devices with decompression were introduced. There is a large amount of research dedicated to examining the efficacy of ILS devices in single-level procedures, but fewer studies focus on their efficacy in 2-level procedures. The purpose of this study was to compare decompression with instrumented posterolateral fusion to decompression with interlaminar stabilization in patients who require surgical treatment at 2 levels for lumbar spinal stenosis at 5 years postoperation. Methods: Of the 322 patients enrolled in the Investigational Device Exemption clinical trial, 116 required surgical treatment at 2 levels. The ILS group consisted of 77 patients, and the fusion group consisted of 39 patients. Efficacy was measured using composite clinical success (CCS). Patients achieve CCS if they achieve all 4 of the following outcomes: >=15-point improvement from baseline Oswestry Disability Index (ODI); no reoperation or epidural injections; no persistent, new, or increasing neurological deficits; and no major device-related complications. Results: There was a 91% rate of follow-up within the participant population in the 5-year data. There was a difference trending toward significance between groups for the absence of reoperation or epidural injection, with 68.8% of ILS patients and only 51.3% of fusion patients meeting this criteria (P = .065); 13.0% of ILS patients and 25.7% of fusion patients required secondary surgery. The percentage of patients achieving overall CCS was much greater in the ILS group than the fusion group, with 55.1% (38/69) of ILS patients and only 36.4% (12/33) of fusion patients achieving CCS at month 60 (P = .077). With regard to the ODI, the visual analog scale back and worse leg pain, the Short Form-12, and the Zurich Claudication Questionnaire, both groups had significantly better results at every follow-up time point when compared to their respective baseline scores. Conclusions: The 2-level ILS patient group performed as well as, if not better than, the 2-level fusion group across almost all outcome measures, demonstrating both clinical outcome success and favorably low reoperation rates in patients who received ILS surgery. Clinical Relevance: This is the first 5-year analysis of the 2-level ILS experience, which supplements previous studies that describe the advantages of ILS by extending such advantages to 2-level cases. PMID- 30276102 TI - Management of Metastatic Spinal Cord Compression in Ireland: Are Surgeons Overlooked? AB - Background: The National Institute of Health and Clinical Excellence (NICE) provide a framework of evidence-based guidelines for the management of metastatic spinal cord compression (MSCC). We aimed to compare our center's provision of service to these best practice guidelines and discuss key shortcomings with their implications for the spinal surgeon. Methods: Patients with radiologic evidence of MSCC over a 30-month period were identified using the hospital electronic radiological database. A chart review was performed analyzing MSCC management. Results: Forty-one patients were identified. Pain was the most common presenting complaint, occurring in 76% of patients. Radiotherapy alone was the most common therapy employed (93% of patients). A surgical opinion was sought for 51% of patients. Histological diagnosis of the causative lesion occurred in 5 patients from surgical specimens. Conclusions: Incongruities between NICE guidelines and our practice exist. Early involvement of the spinal surgical services needs to be encouraged. Establishing a histological diagnosis of the spinal lesion should be seen as of therapeutic importance. PMID- 30276080 TI - We Need to Talk about Lumbar Total Disc Replacement. AB - Background: Replacement of a diseased lumbar intervertebral disc with an artificial device, a procedure known as lumbar total disc replacement (LTDR), has been practiced since the 1980s. Methods: Comprehensive review of published literature germane to LTDR, but comment is restricted to high-quality evidence reporting implantation of lumbar artificial discs that have been commercially available for at least 15 years at the time of writing and which continue to be commercially available. Results: LTDR is shown to be a noninferior (and sometimes superior) alternative to lumbar fusion in patients with discogenic low back pain and/or radicular pain attributable to lumbar disc degenerative disease (LDDD). Further, LTDR is a motion-preserving procedure, and evidence is emerging that it may also result in risk reduction for subsequent development and/or progression of adjacent segment disease. Conclusions: In spite of the substantial logistical challenges to the safe introduction of LTDR to a health care facility, the procedure continues to gain acceptance, albeit slowly. Clinical Relevance: Patients with LDDD who are considering an offer of spinal surgery can only provide valid and informed consent if they have been made aware of all reasonable surgical and nonsurgical options that may benefit them. Accordingly, and in those cases in which LTDR may have a role to play, patients under consideration for other forms of spinal surgery should be informed that this valid procedure exists. PMID- 30276103 TI - The Efficacy of Liposomal Bupivacaine in Lumbar Spine Surgery. AB - Background: Postoperative pain management in spine surgery holds unique challenges. The purpose of this study is to determine if the local anesthetic liposomal bupivacaine (LB) reduces the total opioid requirement in the first 3 days following posterior lumbar decompression and fusion (PLDF) surgery for degenerative spondylosis. Methods: Fifty patients underwent PLDF surgery in a prospective randomized control pilot trial between August 2015 and October 2016 and were equally allocated to either a treatment (LB) or a control (saline) group. Assessments included the 72-hour postoperative opioid requirement normalized to 1 morphine milligram equivalent (MME), visual analog scale (VAS), and hospital length of stay. Results: LB did not significantly alter the 72-hour postoperative opioid requirement compared to saline (11.6 vs. 13.4 MME, P = .40). In a subgroup analysis, there was also no significant difference in opioid consumption among narcotic-naive patients with either LB or saline. Among narcotic tolerant patients, however, opioid consumption was higher with saline than LB (20.6 MME vs. 13.3 MME, P = .048). Additionally, pre- and postoperative VAS scores and hospital length of stay were not significantly different with either LB or saline. Conclusions: In the setting of PLDF surgery, LB injections did not significantly reduce the consumption of opioids in the first 3 postoperative days, nor did the hospital length of stay or VAS pain scores, compared to saline. However, LB could be beneficial in reducing the consumption of opioids in narcotic-tolerant populations. Level of Evidence: 2. PMID- 30276104 TI - Preservation of Spine Motion in the Surgical Treatment of Adolescent Idiopathic Scoliosis Using an Innovative Apical Fusion Technique: A 2-Year Follow-Up Pilot Study. AB - Background: This trial reports the 2-year and immediate postremoval clinical outcomes of a novel posterior apical short-segment (PASS) correction technique allowing for correction and stabilization of adolescent idiopathic scoliosis (AIS) with limited fusion. Methods: Twenty-one consecutive female AIS patients were treated at 4 institutions with this novel technique. Arthrodesis was limited to the short apical curve after correction with translational and derotational forces applied to upper and lower instrumented levels. Instrumentation spanned fused and unfused segments with motion and flexibility of unfused segments maintained. The long concave rods were removed at maturity. Radiographic data collected included preoperative and postoperative data for up to 2 years as well as after long rod removal. Results: All 21 patients are beyond 2 years postsurgery. Average age at surgery was 14.2 years (11-17 years). A mean of 10.5 +/- 1 levels per patient were stabilized and 5.0 +/- 0.5 levels (48%) were fused. Cobb angle improved from 56.1 degrees +/- 8.0 degrees to 20.8 degrees +/- 7.8 degrees (62.2% improvement) at 1 year and 20.9 degrees +/- 8.4 degrees , (62.0% improvement) at 2 years postsurgery. In levels instrumented but not fused, motion was 26 degrees +/- 6 degrees preoperatively compared to 10 degrees +/- 4 degrees at 1 year postsurgery, demonstrating 38% maintenance of mobility in nonfused segments. There was no report of implant-related complications. Conclusions: PASS correction technique corrected the deformity profile in AIS patients with a lower implant density while sparing 52% of the instrumented levels from fusion through the 2-year follow-up. PMID- 30276105 TI - Trends in the Use of Bone Morphogenetic Protein-2 in Adult Spinal Deformity Surgery: A 10-Year Analysis of 54 054 Patients. AB - Background: Bone morphogenetic protein-2 (BMP-2) is an available bone graft option in spinal fusion surgery. The purpose of this study is to investigate the trends of BMP-2 utilization in adult spinal deformity (ASD) surgery. Methods: The Nationwide Inpatient Sample database from 2002 to 2011 was reviewed. Inclusion criteria were patients over 18 years of age who underwent spinal fusion for ASD. Trends of BMP-2 use were examined over time, as well as stratified based on patient and surgical characteristics. All analyses were done after application of discharge weights to produce national estimates. Results: There were 54 054 patients who met inclusion criteria and were included in this study. The overall rate of BMP-2 use was 39.7% (95% confidence interval 35.0%- 44.3%). Overall, there was steady increase in its use over time, with the highest peak in 2009 (55.3% of all cases used BMP-2), and then a decrease up to 37.9% in 2011 (P < .001). The rate of BMP-2 use was significantly higher for patients older than 54 years of age (compared to patients <54, P < .001). It was also higher in females (P = .009), Caucasian patients (P = .006), and Medicare patients (P = .006). Its use was 28.6% in the Northeast, 38.1% in the South, 45.2% in the Midwest, and 48.2% in the West (P = .035). Circumferential procedures had the highest rate of BMP-2 use (44.3%, P = .045). Average total hospital charges were $152,403 +/- 117,454 for patients who did not receive BMP-2 and $205,426 +/- 137,561 for patients who did (P < .001). Conclusion: After analysis of a large nationwide database, it was found that the rate of BMP-2 use in ASD surgery is approximately 40%. There was a significant increase in use from 2002 to 2009, and a decrease thereafter. The highest rates of use were found in older patients, female patients, white patients, Medicare patients, circumferential approaches, and patients undergoing surgery in the Midwest and West regions. PMID- 30276106 TI - Chromium and Nickel Concentrations in Subjects with a Stainless Steel Metal-on Metal Cervical Disc Arthroplasty: Results from a Prospective Longitudinal Study with 7 Years Follow-Up. AB - Background: Cervical disc arthroplasty (CDA) has emerged as an alternative to anterior cervical discectomy and fusion for degenerative cervical disc disease. The artificial discs provide intervertebral motion using multicomponent articulation and thus tend to generate particulate debris and soluble metal ions. Limited information is available on the long-term metal concentrations and associated systemic adverse events observed in metal-on-metal CDA. Serum chromium (Cr) and nickel (Ni) concentrations were assessed in patients implanted with ball in-trough stainless steel-based cervical disc through 7 years. Methods: A prospective, nonrandomized longitudinal study was conducted that included 25 patients following rigorous exclusion criteria that included no previous permanent metal implants and no professional exposure to metal particles. Blood serum Cr and Ni concentrations were assayed preoperatively and at 3, 6, 12, 24, 36, 60, and 84 months postoperatively using high-resolution inductively coupled plasma-mass spectrometry. Longitudinal statistical comparisons were made using the Friedman test with statistical significance at P < .05. Results: Median serum concentrations determined preoperatively and at 3, 6, 12, 24, 36, 60, and 84 months postoperatively were 0.074, 0.106, 0.132, 0.170, 0.172, 0.274, 0.192, and 0.203 ng/mL for Cr and 0.085, 0.178, 0.222, 0.175, 0.205, 0.284, 0.181, and 0.194 ng/mL for Ni. The serum Cr concentrations were statistically higher for all postoperative time periods compared to preoperative concentration (Friedman P <.01), whereas serum Ni concentration was statistically higher at the 84-month postoperative time period than the preoperative concentration (Friedman P <.01) and then the concentration at 3, 12, 24, and 60 months postoperatively (Friedman P < .03). Conclusions: The Cr concentrations detected at all postoperative times were statistically higher than preoperative concentrations, whereas Ni concentration was statistically higher than the preoperative concentration only at 84 months. PMID- 30276107 TI - Comparison of Stand-Alone, Transpsoas Lateral Interbody Fusion at L3-4 and Cranial vs Transforaminal Interbody Fusion at L3-4 and L4-5 for the Treatment of Lumbar Adjacent Segment Disease. AB - Study Design: Retrospective cohort study. Objective: To compare outcomes and complications of stand-alone minimally invasive lateral interbody fusion (LIF) vs revision posterior surgery for the treatment of lumbar adjacent segment disease. Methods: Adults who underwent LIF or transforaminal lumbar interbody fusion (TLIF) for adjacent segment disease were compared. Exclusion criteria: >grade 1 spondylolisthesis, posterior approach after LIF, and L5/S1 surgery. Patient demographics, estimated blood loss, hospital length of stay, complications, reoperations, health-related quality of life measures, and radiographs were examined. Data were analyzed with the chi2, Wilcoxon signed rank, and Mann Whitney U tests. Results: A total of 17 LIF and 16 TLIF patients were included. Demographics were similar. Follow up was similar (LIF: 22.9 +/- 11.8 months vs TLIF: 22.0 +/- 4.6 months; P = .86). The LIF patients had significantly less blood loss (LIF: 36 +/- 16 mL vs TLIF: 700 +/- 767 mL; P < .001) and shorter length of stay (LIF: 2.6 +/- 2.9 days vs TLIF: 3.3 +/- 0.9 days; P = .001). There were no intraoperative complications. Revision rate was 4 of 17 in LIF and 3 of 16 in TLIF (P = .73). Baseline health-related quality of life and radiographic measurements were similar. In both groups, back and leg pain scores significantly improved, and in LIF, the Owestry Disability Index, and EuroQol-5D significantly improved. The LIF had a significant increase in intervertebral height (LIF: 4.8 +/- 2.9 mm, P < .001, TLIF: 1.3 +/- 3.4 mm, P = .37), which was significantly greater for LIF than TLIF (P = .002). Similarly, LIF had a significant increase in segmental lordosis (LIF: 5.6 degrees +/- 4.9 degrees , P < .001, TLIF: 3.6 degrees +/- 8.6 degrees , P = .16), which was not significantly different between groups. Conclusions: Patients with adjacent segment disease may receive significant benefit from stand-alone LIF or TLIF. The LIF offers advantages of less blood loss and a shorter hospital stay.

AB - Background: Studies describing the efficacy of transforaminal percutaneous endoscopic discectomy (TPED) on shortness of recovery and improvement of postoperative quality of life are limited, especially regarding gender, something that has never been reported before in the literature. The purpose of this study is to evaluate, in accordance with the sex of the patients, possible differences in the health-related quality of life of those who underwent TPED for lumbar disc herniation (LDH). Methods: A total of 76 patients diagnosed and treated with TPED for LDH with 1-year follow-up were selected and divided into 2 groups of equal number depending on sex. Their quality of life was evaluated by using the 36-Item Short Form Health Survey before the operation, then 6 weeks and 3, 6, and 12 months postoperatively. A statistical analysis was conducted, in order to compare the 8 scaled scores of the 36-Item Short Form Health Survey, each time combining 2 chronological phases for the total number of patients, for each group, and between groups. Results: Fifty-two (68.4%) patients were <=63 years old, whereas the other 24 (31.4%) were >63 years old (mean +/- SD = 56.5 +/- 12.1 years). Apart from the physical function domain, the scores were higher in every visit for the 2 groups, but the change between groups was not significant. Women had a significantly higher increase of physical function score in 3 months after TPED and in the interval 6 weeks to 3 months compared with men. However, in the intervals 3 to 6 months and 3 to 12 months, men presented a significantly higher increase compared with women. Conclusions: Statistically significant improvement of the quality of life for both men and women was observed. Generally, there was no significant difference between the 2 groups. With regard to the physical functioning, it appears to be a significant difference that is counterpoised over time. Level of evidence: 2. Clinical relevance: Transforaminal percutaneous endoscopic discectomy for LDH does not present major differences in the improvement of quality of life regarding gender. PMID- 30276109 TI - Preclinical Comparison of Thermal Tissue Effects from Traditional Electrosurgery and a Low-Temperature Electrosurgical Device during Anterior Cervical Discectomy and Fusion. AB - Background: Exposure of the anterior cervical spine requires dissection in proximity to critical neurovascular structures. Monopolar electrosurgical (ES) devices generate heat in contacted tissues, resulting in thermal damage and temperature change. This study examined depth of thermal injury and temperature change associated with use of a low-temperature electrosurgical device (LTD) compared to traditional electrosurgery during a cadaveric anterior cervical discectomy and fusion (ACDF) dissection. Methods: ACDF was performed, using ES or LTD, on cervical spines (C3-4 and C4-5) from 2 fresh human cadavers with intact neck soft tissues and no history of surgery. Cadavers were maintained at 22-23 degrees C, and fiber-optic temperature sensors (Neoptix, Quebec City, Quebec, Canada) were placed near relevant structures to measure changes during dissection. Depth of thermal injury was assessed by hematoxylin and eosin and Masson's trichrome histology of fixed tissue specimens. Results: Use of the LTD resulted in a statistically significant reduction in temperature change at platysma (3.0 +/- 1.04 vs. 11.41 +/- 3.10 degrees C, P = .003), carotid sheath (7.32 +/- 1.13 vs. 15.57 +/- 2.56 degrees C, P = .007), and longus colli (6.11 +/ 1.32 vs. 12.9 +/- 3.62 degrees C, P = .016) compared to ES. Temperature change at the trachea was similar between groups (6.06 +/- 1.99 vs. 4.96 +/- 1.89 degrees C, P = .528). Histology showed that LTD produced less mean and maximal depth of thermal injury compared to ES (mean: 0.5 vs. 1.2 mm; max: 0.9 vs. 1.8 mm; P < .05). Conclusions: The results of this pilot study demonstrate that anterior cervical spine exposure using an LTD reduces tissue temperature change and depth of thermal injury compared to ES. Clinical Relevance: Although exploratory, these results suggest that use of an LTD during ACDF may reduce the extent of thermal tissue injury during dissection. Future studies in live animal models are warranted to determine if thermal injury is a potential cause of common exposure-related complications, such as dysphagia and dysphonia.

AB - Background: It is unclear whether patients can be taken off suppressive antibiotics with infected retained instrumentation. This study aimed to retrospectively analyze the perioperative course and antibiotic regimen that led to the clinical intervention of patients with infected spinal instrumentation. Methods: Consecutive adult patients with spine instrumentation who suffered surgical site infections (SSI) requiring debridement were retrospectively analyzed. The patients were grouped into 4 cohorts based on their clinical intervention: removal of instrumentation, reinstrumentation, retention of instrumentation with continued antibiotic suppression, and retention of instrumentation with no antibiotic suppression. Patient factors, infection factors, debridement, and antibiosis were compared. Results: Of the 67 patients with SSI after spine surgery and instrumentation, 19 (28%) had their instrumentation removed, 6 (9%) had their instrumentation exchanged, 25 (37%) had their instrumentation retained and were on antibiotic suppression, and 17 (25%) had their instrumentation retained without any suppression. Those who had their instrumentation removed had a later presentation of their infection averaging 85 days (range 6-280 days) postoperatively. There was an earlier presentation for those who retained their implants, with suppression averaging 19 days (range 9 39) and no suppression averaging 29 days (range 6-90 days) post operatively (P < .001). Conclusions: None of the patients with retained instrumentation without suppression had recurrence of infections after long-term follow-up. Lifelong antibiotic suppression may not be required with SSI that present early after early aggressive debridement. Patients with infections detected later are difficult to treat without removal of their original instrumentation. Clinical Relevance: This study presents the outcomes of surgical and antibiotic factors in patients with infected spinal instrumentation.

AB - Background: Very little normative computed tomography (CT) scan data exist defining expected relationships of vertebral structures in the intact cervical spine. Better understanding of normal relationships should improve sensitivity of injury detection, particularly for facet subluxation. The purpose of this paper was to describe the normal anatomical relationships and most sensitive measurements to detect abnormal alignment in the subaxial cervical spine. Methods: A group of 30 CT scans with no documented cervical spine injury were utilized from an established database in a trauma population. Twenty-two anatomical measurements were made for each level of the subaxial cervical spine using Microview software. For the purposes of measurement, the upper confidence limit of normal was reported as two standard deviations from the mean. Results: The novel, CT based measurements of bone articulation were generally smaller and had lower confidence intervals compared to traditional radiographic measurements of midline structures (such as interspinous distance, interlaminar widening, disc space widening). The upper limit of normal of facet joint height was reported (1.54 mm anterior, 1.27 mm posterior, and 2.0 mm midportion), which may help identify distractive-flexion injuries. The upper limit of normal vertebral translation (2.0 mm) was also reported to identify translation/rotation injuries. Conclusions: Normal CT measurements for the subaxial cervical spine, especially in the facets, were found to have small confidence limits and variation. Based upon these findings, we conclude that facet measurements and translation may be better screening tools than traditional radiographic criteria based upon midline structures. Using these measurements may improve detection of cervical spine injuries warranting further imaging or investigation and reducing missed injuries. Clinical Relevance: Improved understanding of normal anatomic measures in the subaxial spine will allow for better screening and identification of injuries. PMID- 30276111 TI - Suitability of Administrative Databases for Durotomy Incidence Assessment: Comparison to the Incidence Associated With Bone-Removal Devices, Calculated Using a Systemic Literature Review and Clinical Data. AB - Background: Durotomy is a major complication of spinal surgery, potentially leading to additional clinical complications, longer hospitalization, and increased costs. A reference durotomy incidence rate is useful for the evaluation of the safety of different surgical aspects. However, the literature offers a wide range of incidence rates, complicating this comparison. Theoretically, a reference incidence value can be extracted from administrative databases, containing a large number of procedures. However, it is suspected that these databases suffer from underreporting of complications. This study aims to evaluate durotomy incidence using several large-scale databases and to assess the ability to use it as a reference by comparison to durotomy incidences directly associated with 4 bone removal devices, including the commonly used high-speed drill. Methods: Durotomy overall incidence was estimated from several administrative databases using different methods in order to achieve minimal and maximal estimations. Durotomy incidences for 3 bone removal devices were derived using literature meta-analysis, and the incidence for the fourth device was calculated using clinical data. Results: The incidence range of durotomy according to the databases was 2.8-3.5%. The calculated incidence of durotomy for the studied devices was 0.4-2.91%. The highest rate, 2.91%, is associated with the commonly used high-speed drill combined with Kerrison Rongeur and bone punches. Since bone-removal devices are just one of the possible causes of dural tears, the general incidence is expected to be higher than the incidence associated with the devices, yet even the maximal estimation, 3.5%, was only slightly higher, suggesting that the speculation of underreporting of dural tears to these databases is probably true, as also supported by the mostly higher incidences reported in the literature. Conclusions: Hospital administrative databases seem to show a lower-than-reasonable incidence of durotomy, suggesting possible underreporting. Researchers should therefore use this tool with caution. Reduction of the absolute durotomy incidence by approximately 2.5% can be achieved by improving the safety of bone-removal devices. PMID- 30276113 TI - Biomechanics of an Expandable Lumbar Interbody Fusion Cage Deployed Through Transforaminal Approach. AB - Background: A novel expandable lumbar interbody fusion cage has been developed which allows for a broad endplate footprint similar to an anterior lumbar interbody fusion; however, it is deployed from a minimally invasive transforaminal unilateral approach. The perceived benefit is a stable circumferential fusion from a single approach that maintains the anterior tension band of the anterior longitudinal ligament. The purpose of this biomechanics laboratory study was to evaluate the biomechanical stability of an expandable lumbar interbody cage inserted using a transforaminal approach and deployed in situ compared to a traditional lumbar interbody cage inserted using an anterior approach (control device). Methods: Twelve cadaveric spine specimens (L1-5) were tested intact and after implantation of both the control and experimental devices in 2 (L2-3 and L3-4) segments of each specimen; the assignments of the control and experimental devices to these segments were alternated. Effect of supplemental pedicle screw-rod stabilization was also assessed. Moments were applied to the specimens in flexionextension (FE), lateral bending (LB), and axial rotation (AR). The effect of physiologic preload on construct stability was evaluated in FE. Segmental motions were measured using an optoelectronic motion measurement system. Results: The deployable expendable transforaminal lumbar interbody fusion (TLIF) cage and control devices significantly reduced FE motion with and without compressive preload when compared to the intact condition (P < .05). Segmental motions in LB and AR were also significantly reduced with both devices (P < .05). Under no preload, the deployable expendable TLIF cage construct resulted in significantly smaller FE motion compared to the control cage construct (P < .01). Under all other testing modes (FE under 400N preload, LB, and AR), the postoperative motions of the 2 constructs did not differ statistically (P > .05). Adding bilateral pedicle screws resulted in further reduction of range of motion for all loading modes compared to intact condition, with no statistical difference between the 2 constructs (P > .05). Conclusions: The ability of the deployable expendable interbody cage in reducing segmental motions was equivalent to the control cage when used as a standalone construct and also when supplemented with bilateral pedicle screw-rod instrumentation. The larger footprint of the fully deployed TLIF cage combined with preservation of the anterior soft-tissue tension band may provide a better biomechanical fusion environment by combining the advantages of the traditional anterior lumbar interbody fusion and TLIF approaches. PMID- 30276114 TI - Comparison of Surgical Outcome Between Diabetic Versus Nondiabetic Patients After Lumbar Fusion. AB - Background: The prevalence of diabetes mellitus (DM) is increasing worldwide. Thereby, an increasing rate of patients with DM are subjecting to spine surgery. Reviewing the literature, a higher rate of surgery-related complications is reported in DM patients. There is no prospective study comparing the outcomes of lumbar fusion surgery in patients with and without DM. We aimed to investigate whether DM is associated with worse patient-reported outcomes, lower fusion rate, and higher complication rate in subjects undergoing spinal lumbar fusion surgery. Methods: Forty-eight subjects with DM (DM group) and 48 controls (control group) were recruited. Data regarding age, duration of diabetes, comorbidities, fasting blood sugar, HbA1c, insulin dependence, duration of operation and the volume of bleeding, and the number of infused packed cell were recorded for all patients. Pain and functional status of the patients using the visual analogue scale (VAS) and Oswestry Disability Index (ODI) were measured before operation and 2 weeks, 6 months, and 1 year after lumbar spinal fusion surgery. Using lumbar computed tomography scan and anteroposterior and lateral x-ray 1 year after the surgery, fusion was assessed. Results: Fusion rate after 1 year was 78% in the control group and 53% in the DM group (P = .02). Patients with DM had higher VAS scores comparing to controls 1 year after the operation, but the difference was not significant (P = .07). However, comparing the functional status of the subjects, significantly higher ODI scores were found among DM patients comparing to controls (P = .002). Conclusion: Rate of fusion among diabetic patients who undergo lumbar spinal fusion surgery is lower than healthy controls. Spine surgeons should consider this to provide the best possible facilities during the surgery to increase the fusion rate in these patients.

AB - Biologically engineered products are medical devices offer support and structure for wound healing by providing a scaffold for cell growth and proliferation. In the field of plastic surgery, these devices are being used to improve the outcomes of surgical closure in selected patients. The purpose of this article is to provide an overview of the source, indications, mechanisms, and outcomes of commonly used biologic products in wound healing.

PMID- 30276120 TI - Quantitative Monitoring Wound Healing Status Through Three-dimensional Imaging on Mobile Platforms. AB - There are approximately 6.5 million patients in the U.S. suffering from chronic wounds and approximately 140,000 patients hospitalized every year with new wounds. With a long healing process, this demands the need for a non-contact, low cost, and remote monitoring solution that can assist clinicians in diagnosing and treating a patient's wound. This will reduce the burden of countless office visits, especially for those who are elderly and incapacitated. We present a mobile platform based wound 3D imaging app. The app is the only integrated measurement solution encompassing wound area and volume through low cost yet accurate 3D imaging. Extensive experiments show the app has 1.14% and 4.41% relative errors for wound area and volume measurement respectively, far exceeding currently employed clinic methods. In addition, non-invasive volume measurement methods currently use expensive industrial 3D (>$20K) cameras, but our solution provides cheap and accurate results. PMID- 30276121 TI - Limb-Threatening Arterial Thrombosis in a Patient with Eosinophilic Granulomatosis with Polyangiitis. AB - Eosinophilic granulomatosis (EGPA), or Churg-Strauss syndrome, is a rare and necrotizing systemic vasculitis, which affects small-to-medium-sized vessels and often manifests with severe asthma and eosinophilia. We report a case of a 72 year-old male with a two-year lung-biopsy proven history of EGPA who presented with retiform purpura and patchy necrosis on his bilateral shins, which progressed to sharply demarcated, stellate ulcerations with surrounding erythema within two weeks. Laboratory work up revealed elevated anti-Cardiolipin IgM, rheumatoid factor, erythrocyte sedimentation rate, and C-reactive protein, although P-neutrophil cytoplasmic antibody (P-ANCA) and C-neutrophil cytoplasmic antibody (C-ANCA) were negative. Vascular studies revealed long anterior tibial and dorsalis pedis artery occlusion and severe small vessel disease in plantar digital arteries. Despite treatment with intravenous cyclophosphamide, pulse-dose methylprednisolone, and pentoxifylline, the patient experienced disease progression and limb threatening arterial thrombosis. This case highlights the importance of vascular and neuropathic sequelae that may result from untreated or undertreated EGPA in P-ANCA-negative patients without active pulmonary symptoms. PMID- 30276122 TI - Placental Membranes for Management of Refractory Cutaneous Sinus Tracts of Surgical Origin: A Pilot Study. AB - Despite advances in surgical technique, postoperative complications may lead to refractory cutaneous sinus tracts or tunnels. Negative pressure wound therapy is difficult to apply in longer tracts with a narrow diameter opening and conservative treatment failures ultimately necessitate surgical revisions. The aim of this pilot study was a clinical utility assessment of two different commercial placental membrane products for refractory cutaneous sinus tracts of surgical origin. Patients were treated with viable cryopreserved placental membrane (vCPM, n = 6) or devitalized dehydrated amnion/chorion membrane (dHACM, n = 6). The primary outcome measurement was the proportion of complete sinus tract depth resolution without exudate. Secondary endpoints included 4-week percent reduction in sinus tract probing depth and peri-tract wound surface area, days and number of grafts to resolution, number of wound-related infections, and 1-year recurrence rate for closed sinus tracts. All vCPM patients demonstrated complete sinus tract resolution compared to zero closures in the dHACM group (p = 0.00216). The vCPM group achieved greater percent reduction in probing depth (73.3 +/- 21.9 versus -4.4 +/- 91.3) and surrounding wound surface area (34.8 +/- 86.8 versus -279.3 +/- 454.9) at 4 weeks than dHACM. The use of viable intact cryopreserved placental membrane has demonstrated positive clinical outcomes for the treatment for refractory exudative sinus tracts and may be an alternative to repeat surgical intervention.

AB - The concept of the Kennedy Terminal Ulcer (KTU) has been ubiquitous in attempting to explain the development of pressure based tissue injuries in patients with actual or presumed terminal conditions. The concept is problematic in that it uses factors other than pressure to explain the development and progression of pressure based tissue injuries, specifically the presence of a terminal condition. Based on the most current understanding of how pressure based tissue injuries develop and progress, the concept of The Kennedy Terminal Ulcer appears to be without physiologic basis and based solely on observation. Since systemic factors affect all tissues with relative equality, the development of a single locus of injury must logically be based on a single locus of cause and affect. The presumption that a single locus of injury will develop in an arbitrary location based on a systemic set of factors is untenable. A new concept called Miller Pressure Equivalent Injuries is proposed to refute the concept of a single pressure based tissue injury developing based solely on terminal systemic factors and why these previously presumed terminal condition associated pressure based injuries occur.

AB - A 59-year-old African American female presented to a plastic surgery office in consultation for a very painful non-healing wound of her right lateral malleolus. An incisional biopsy was performed and ultimately a diagnosis of hydroxyurea induced ulcer was concluded. Descriptions of this entity are rare in the surgical and wound care professional literature. This diagnosis does appear in the hematology/oncology literature; however, these practitioners may not be the first to examine a patient with the development of such an ulcer.

AB - Pharmaceutical Co-crystals are not new, they have gained much attention since the last decade among scientists and pharmaceutical industry. Pharmaceutical co crystals are multicomponent systems composed of two or more molecules and held together by non-covalent interactions. The development of pharmaceutical co crystals, a new solid crystalline form, offer superior physico-chemical properties (such as melting point, stability, solubility, permeability, bioavailability, taste masking, etc.) without altering the pharmacological properties. Recently, with the upsurge in the growth of Pharmaceutical co crystals, the major concern is over the regulatory status of co-crystals. With the new guidelines from United States Food and Drug Administration (USFDA) and European Medicines Agency (EMA), the status has become even more complicated due to significantly different opinions. This review highlights whether co-crystals fulfil the requirements for the grant of a patent or not and how cocrystals are going to affect the present scenario of pharmaceuticals. PMID- 30276133 TI - Isotretinoin; A review on the Utilization Pattern in Pregnancy. AB - Purpose: Isotretinoin is the most effective anti-acne drug with a long-term remission. However; it contains severe teratogenic effects with serious adverse drug reactions, which limits the use of medication. Methods: To review the use of isotretinoin during pregnancy, we carried out a comprehensive search of literature in Google Scholar, Scopus and PubMed/Medline from their inception until April 2015. Results: Database searching identified 277 records, of which, 38 articles were retrieved according to abstract and title assessment. After full text review, 17 articles were excluded and finally, a total of 21 studies met the inclusion criteria. Data showed an increased pattern in the use of isotretinoin. In some studies, health care providers were not fully adhered to the risk reduction programs in pregnancy. Exposing to isotretinoin among pregnant women has still occurred due to detrimental adherence to risk reduction programs which resulted in live-born infants with different kinds of abnormalities. Conclusion: Despite the known serious adverse effect of isotretinoin, the use of drug was not based on the guidelines in some cases, which needs more attentions to prevent the severe drug related problems.

AB - Heavy metals taken into the organism can make the toxic effects on the metabolism in various ways. For example, they may interact with proteins to alter and inhibit their enzymatic and structural functions. Mercury is one of the toxic elements that are widely distributed in nature. Mercury toxicity poses a serious threat to human health. It is an element that causes oxidative stress to increase in individuals, leading to tissue damage. Oxidative stress is the result of the imbalance between the production of oxidative species and cellular antioxidant defense. Phytotherapy continues to play an important role in health care. Natural phytotherapeutic antioxidants, exhibit a broad sequence of biological impacts, including anti-oxidative stress, anti-aging, anti-toxicicity and anticancer. Many studies have also shown that the phytotherapeutic agents play an important role in the removal of mercury from the tissue and in reducing oxidative stress. Our goal in this review was to investigate alternative ways of extracting the mercury in the tissue. PMID- 30276135 TI - Nanotechnology in Wound Healing; Semisolid Dosage Forms Containing Curcumin Ampicillin Solid Lipid Nanoparticles, in-Vitro, Ex-Vivo and in-Vivo Characteristics. AB - Purpose: Wound healing is a natural biologic process, but the duration of it may take too long. Trying to shorten this process is one of the challenges for scientists. Many technologies were applied to achieve this goal as well as nanotechnology. In this study semi solid formulations containing curcumin and ampicillin solid lipid nanoparticles (SLNs) were prepared to evaluate as burn wound healing agent. Methods: Curcumin as an anti-inflammatory and anti-bacterial agent and ampicillin as an antibiotic were applied. In-vitro and in-vivo evaluations were carried out. Particle size, loading efficiency, release profile, morphology and anti-bacterial efficacy of desired nanoparticles were evaluated at first. Then the remaining of the antibacterial effect in semi solid preparations was studied. Animal studies for both toxicology using rabbits and skin burn model using rats were designed. Pathology studies after applying of formulations was done too. Results: Desired nanoparticles were spherical in shape and particle size in range of 112-121 nm, with low zeta potential. For increasing stability of particles they were freeze dried using cryoprotectant. Lyophilized particles show no significant size enlargement. Results showed that both ointment and gel preparations have reasonable anti-bacterial effects, both of them cause increasing in the rate of wound healing in comparison with placebos and control groups and none of the formulations showed acute toxicity. Conclusion: It seems that using nanotechnology could shorten wound healing process to reduce treatment costs and increase compliance of patients. PMID- 30276134 TI - Targeted Co-Delivery of Docetaxel and cMET siRNA for Treatment of Mucin1 Overexpressing Breast Cancer Cells. AB - Purpose: Targeted treatment of breast cancer through combination of chemotherapeutic agents and siRNA had been drawing much attention in recent researches. This study was carried out to evaluate mucin1 aptamer-conjugated chitosan nanoparticles containing docetaxel and cMET siRNA on SKBR3 cells. Methods: Nano-drugs were characterized by transmission electron microscope, Zetasizer and loading efficiency calculation. siRNA entrapment onto nanoparticles, stability of siRNA-loaded nanoparticles and conjugation of mucin1 aptamer to nanoparticles were evaluated via separate electrophoresis. Cellular uptake of the targeted nanoparticles was evaluated through GFP-plasmid expression in mucin1+ SKBR3 vs. mucin1- CHO cells. Protein expression, cell viability and gene expression were assessed by Western Blotting, MTT assay, and Quantitative Real Time-PCR, respectively. Results: Characterization of nano-drugs represented the ideal size (110.5+/- 3.9 nm), zeta potential (11.6+/- 0.8 mV), and loading efficiency of 90.7% and 88.3% for siRNA and docetaxel, respectively. Different gel electrophoresis affirmed the conjugation of aptamers to nanoparticles and entrapment of siRNA onto nanoparticles. Increased cellular uptake of aptamer conjugated nanoparticles was confirmed by GFP expression. cMET gene silencing was confirmed by Western Blotting. The significant (p <=0.0001) impact of combination targeted therapy vs. control on cell viability was shown. Results of Quantitative Real Time-PCR represented a remarkably decreased (p <=0.0001) expression of the studied genes involving in tumorigenicity, metastasis, invasion, and angiogenesis (STAT3, IL8, MMP2, MMP9, and VEGF) by targeted combination treatment vs. control. Conclusion: The mucin1 aptamer-conjugated chitosan nanoparticles, containing docetaxel and cMET siRNA, is suggested for treatment of mucin1+ metastatic breast cancer cells. However, further studies should be conducted on animal models. PMID- 30276136 TI - Comparison of Pectin Layers for Nicotine Transdermal Patch Preparation. AB - Purpose: The objective of the present investigation was to prepare and evaluate transdermal patches for nicotine. Methods: Pectin isolated from the hulls of Monthong durian or leaves of Krueo Ma Noy was used as a matrix membrane for the controlled release of nicotine and compared with commercial pectin. The mechanical properties, moisture uptake, and Fourier transform infrared spectra were characterized. The in vitro stability of these patches was evaluated and compared to commercial nicotine patches. Results: The mechanical properties of the patches made from isolated pectin were greater than those prepared from commercial pectin; brittle commercial patches were obtained after nicotine loading. The moisture uptake of the patches made with isolated pectin was in the range of 30.20-44.29%. There was no incompatibility between the ingredients of the nicotine transdermal patches or any degradation of the drug. The matrix layer made from isolated pectin controlled the nicotine release more effectively than did commercial nicotine patches. In addition, these patches were stable at in a refrigerator (approximately 4+/-2 degrees C) and at ambient temperature (approximately 30+/-2 degrees C) for 3 months, retaining 90% of the loaded nicotine. Conclusion: Our study suggests that using isolated pectin as the matrix layer should control the release of nicotine from transdermal patches. PMID- 30276137 TI - Enhanced Intestinal Permeation of Doxorubicin Using Chitosan Nanoparticles. AB - Purpose: Due to limited oral bioavailability of doxorubicin (Dox) many efforts during the last decades focused on the development of novel delivery systems to overcome these limitations. In the present study, Dox encapsulated chitosan nanoparticles were prepared to evaluate the intestinal permeation of Dox via oral administration. Methods: Nanoparticles were fabricated based on ionic gelation method using tripolyphosphate. Some physicochemical properties, such as nanoparticle size and morphology, loading efficiency and in vitro drug release in 3 different pH values (5.0, 6.8 & 7.4) were evaluated. Intestinal permeations of free Dox and Dox loaded in nanoparticles were assessed using rat intestinal sac model. Results: The nanoparticles were spherical shape with average size of 150 +/- 10 nm. The entrapment and loading efficiency of Dox were up to 40% and 23%, respectively. According to the release profiles, up to 30% of loaded drug was released within 6hrs and the remaining amount of Dox was released more gradually, but this pattern was related to pH of the medium. The amount of drug released at acidic condition (pH 5.0) was greater than other pHs. The intestinal permeation of Dox increased nearly up to 90% by loading in chitosan nanoparticles. Conclusion: Using chitosan nanoparticles presents a potential safe drug delivery system for oral administration of Dox. In vivo studies and the determined pharmacokinetic and pharmacodynamic of Dox loaded chitosan nanoparticles after oral administration are planned for future studies. PMID- 30276138 TI - Fabrication and Characterization of Gliclazide Nanocrystals. AB - Purpose: The main aim of the present investigation was to enhance the solubility of poorly soluble Gliclazide by nanocrystallization. Methods: In present investigation gliclazide nanocrystals were prepared by sonoprecipitation using Pluronic F68, Poly Vinyl Alcohol (PVA), Poly ethylene Glycol 6000 (PEG), Poly Vinyl Pyrrolidine (PVP K30) and Sodium Lauryl Sulphate (SLS) as stabilizers. Fourier Transform Infrared Spectroscopic study (FTIR), Differential Scanning Calorimetry (DSC) and X ray diffraction (XRD) studies were conducted to study the drug interactions. Size and zeta potential of the nanocrystals were evaluated. In vitro and in vivo studies of nanocrystals were conducted in comparison to pure gliclazide. Results: The Gliclazide nanocrystals (GN) showed mean particle size of 131+/-7.7 nm with a zeta potential of -26.6 mV. Stable nanocrystals were formed with 0.5% of PEG 6000. FTIR, DSC and XRD studies of nanocrystals showed absence of interactions and polymorphism. SEM photographs showed a change in morphology of crystals from rod to irregular shape. There is an increase in the saturation solubility and the percentage drug release from formulation GN5 (Optimized Gliclazide Nanocrystals) was found to be 98.5 in 15 min. In the in vivo study, GN5 nanocrystals have reduced the blood glucose level to 296.4+/-4.26 mg/dl in 12 hr. The nanocrystals showed lower tmax and higher Cmax values as compared to pure gliclazide. Conclusion: The prepared nanocrystals of gliclazide were stable without any drug polymer interactions. Increase in the dissolution of nanocrystals compared to pure gliclazide and significant reduction in blood glucose level in vivo indicated better bioavailability of the nanocrystals. Therefore, it is concluded that nanocrystal technology can be a promising tool to improve solubility and hence dissolution of a hydrophobic drug. PMID- 30276139 TI - Effect of Ghrelin on Caspase 3 and Bcl2 Gene Expression in H2O2 Treated Rat's Bone Marrow Stromal Cells. AB - Purpose: The antiapoptotic effect of ghrelin in various cell lines including bone marrow stromal cells (BMSCs) has been proved. However, the real mechanism of this effect is not clear. Caspase3 and Bcl2 are well-known pro- and antiapoptotic regulatory genes in eukaryotes. The aim of the study was to find out the effect of ghrelin on Caspase 3 and Bcl2 change in BMSCs. Methods: Rat BMSCs were cultivated in DMEM. Passage 3 BMSCs were treated with ghrelin 100 MUM for 48 h. Real-time PCR for Caspase 3 and Bcl2 was carried out from B (untreated BMSCs), BH (BMSCs treated with 125 uM H2O2), BGH (BMSCs treated with 100 uM ghrelin then 125 uM H2O2) and BG (BMSCs treated with 100 uM ghrelin) groups. For immunofluorescence, cells were incubated with anti Caspase 3 and Bcl2monoclonal antibodies. Primary antibodies were visualized using the FITC method. All data are presented as means +/- SEM. Values of P<0.05 were considered statistically significant. Results: Ghrelin decreased mRNA expressions of Caspase-3 significantly as compared to the BH group (P<0.05). Also, Bcl-2 gene expression showed an increment in BG group as compare with BH and BGH groups (P<0.05). A high present of Bcl-2 positive cells were observed in the BGH group while Caspase 3 positive cells were significantly decreased in the BGH group compared with the BH group (P<0.05). Conclusion: Ghrelin probably enhances BMSCs viability through regulation of pro- and antiapoptotic genes Caspase 3 and Bcl2. However the signaling pathway of this effect should be elucidated in the future. PMID- 30276140 TI - Snail-1 Silencing by siRNA Inhibits Migration of TE-8 Esophageal Cancer Cells Through Downregulation of Metastasis-Related Genes. AB - Purpose: Snail-1 is a transcription factor, which takes part in EMT, a process related to the emergence of invasion and cancer progression. The purpose of this study was to evaluate the effect of Snail-1 silencing on the human esophageal squamous cell carcinoma cell line, namely TE-8, in vitro. Methods: In this study, transfection of Snail-1 specific siRNA was conducted into TE-8 cells. The relative mRNA expression levels of Snail-1, Vimentin, CXCR4 and MMP-9 and transcription levels of miR-34a and let-7a were investigated by quantitative Real time PCR. Western blotting was carried out to evaluate the Snail-1 protein level. Migration assay of TE-8 cells was also performed following the presence or absence of Snail-1 specific siRNA. MTT and TUNEL assays were performed to evaluate cell viability after Snail-1 silencing. Results: It was found that treatment of cancer cells with the Snail-specific siRNA effectively downregulated the expression of Snail-1 in both mRNA and protein levels, and vimentin, CXCR4, and MMP-9 in mRNA level. However, it elevated the transcript levels of miR-34a and let-7a expressions. Furthermore, transfection of cancer cells with the Snail specific siRNA significantly induced apoptosis in TE8 cells. Moreover, suppression of Snail-1 led to diminished cell migration. Conclusion: It seems that Snail-specific siRNA can significantly interrupt esophageal cancer cell migration and reduce metastatic-related factors and induce miR-34a and let-7a in vitro. The bottom line is that therapeutic approaches via targeting Snail-1 can be used for ESCC treatment, suggesting that other possible target molecules for ESCC therapy require to be explored. PMID- 30276141 TI - Simulation and Stability Assessment of Anti-EpCAM Immunotoxin for Cancer Therapy. AB - Purpose: Epithelial cell adhesion molecule (EpCAM) is a dominant antigen in human colon carcinoma tissue. Topology features of this antigen are different in normal and malignant conditions; for instance, EpCAM is much less accessible to antibodies in normal cells than in cancerous tissues. Hence, EpCAM has been considered as a suitable candidate for cancer target therapy via immunotoxins (ITs) development. In this study, attention was focused on the stability assessment of anti-EpCAM-IT (anti-Ep-IT) to design a novel IT. Methods: The 3D structures of the antibody template and the toxin segment of anti-Ep-IT were retrieved from PDB. Discovery Studio3.0 was used to separate the ligands and water molecules. The antibody (Ab) fragment of anti-Ep-IT was aligned using protein blast (BLAST-p), and SWISS-MODEL database was used for Ab modeling. IT modeling was accomplished using MODELLER 9.15. Also, GROMACS 5.07 was used for molecular dynamic (MD) simulation step. Moreover, ERRAT and RAMPAGE databases were used for quality assessment of the structures. Results: BLAST-p results indicated that antibody moiety of IT has the highest E-value and query coverage scores to the monoclonal antibody (mAb) 4D5MOC-B. Modeling by SWISS-MODEL provided a reasonable template for Ab portion compared to MODELLER. The best modeled full-length IT with the lowest RMSD values was selected. Finally, RMSD plot for MD stage demonstrated constant values from 7000ps to 20000ps. Conclusion: In general, both modeling results and their quality evaluations were satisfactory for designing IT. Moreover, RMSD plot revealed that IT stability was preserved during the simulation. Overall, our findings led to modeling and simulation of the anti-Ep-IT with more structural stability.

AB - Purpose: Application of Mummy material for treatment of different diseases such as bone fracture, cutaneous wounds and joint inflammation has been advised since hundred years ago in Persian traditional medicine. Due to the claims of indigenous people and advice of traditional medicine for application of this material in healing of bone fractures, this study has been designed to evaluate whether Mummy material can promote the differentiation of mesenchymal stem cells into osteoblasts and enhance the expression of bone specific genes and proteins. Methods: Adipose derived stem cells (ASCs) at fourth cell passage were divided into control, osteogenesis group (received osteogenic medium), Mummy group (received Mummy at concentration of 500 ug/ml). ASCs in the fourth group were treated with both osteogenic medium and Mummy (500ug/ml). Cells in all groups were harvested on days 7, 14 and 21 days for further evaluation through Real time RT-PCR, Von kossa staining, Immunocytochemistry and flowcytometery. Results: Treatment of ASCs with Mummy at concentration of 500ug/ml promotes the expression level of Osteocalcin, RUNX-2 and beta1-integrin genes in different time points but that of the Osterix did not changed. Furthermore the expression of Osteocalcin protein enhanced significantly in ASCs treated with Mummy detected by Immunocytochemistry and flowcytometery technique compared to the control groups. The results of this study also showed that treatment of ASCs with Mummy resulted in formation of mineral deposits which was evaluated by Von Kossa staining method. Conclusion: Obtained data from this study reveals that Mummy is a potent enhancer for differentiation of ASCs into osteoblasts in in vitro system, probably through increasing the level of bone specific genes and proteins. PMID- 30276143 TI - Dual Preconditioning: A Novel Strategy to Withstand Mesenchymal Stem Cells against Harsh Microenvironments. AB - Purpose: Poor survival rate of mesenchymal stem cells (MSCs) following their transplantation is one of the major challenges in their therapeutic application. Therefore, it is necessary to augment the viability of the MSCs in order to improve their therapeutic efficacy. Several strategies have been used to overcome this problem. Preconditioning of MSCs with oxidative stresses has gained a lot of attention. Therefore, in the present study, we investigated the effects of simultaneous preconditioning of MSCs with hydrogen peroxide and serum deprivation stresses on their survival and resistance to stressful conditions. Methods: MSCs were isolated from human umbilical cord blood. To perform simultaneous preconditioning, the cells were cultured in DMEM medium containing 1, 2.5 and 5 percent FBS and different concentrations of H2O2 (5, 10, 15, 20, 25, 30, 35, 40, 50, 60, 80 and 100 uM) for 24 hrs. Then, the cells were cultured in recovery culture medium. Finally, one group of the cells was exposed to a lethal concentration of H2O2 (300uM), and the other cells were cultivated in FBS free DMEM medium as the lethal situation. In addition, the percentage of apoptotic cells was analyzed using Caspase 3 assay kit. Results: Simultaneous preconditioning of the MSCs with 15uM H2O2 plus serum deprivation, 2.5% FBS, significantly increased the resistance of the cells to the toxicity induced following their cultivation in FBS free DMEM medium. It exerted the protective effect on the cells after treating with the lethal dose of H2O2 as well. Conclusion: Simultaneous preconditioning of MSCs with oxidative and serum deprivation stresses enhances their survival against harsh conditions, which might increase the viability and stability of the MSCs following their transplantation. PMID- 30276144 TI - Impact of Omega-3 Supplementation on High Sensitive C-Reactive Protein Level and 30-Day Major Adverse Cardiac Events After the Implementation of Coronary Stent in Patients with Chronic Kidney Disease: A Randomized Clinical Study. AB - Purpose: Studies have revealed that patients with chronic kidney disease (CKD) are more susceptible to adverse effects of percutaneous coronary intervention (PCI). In addition, the role of elevated high sensitive C-reactive protein (hs CRP) in the prediction of adverse cardiac outcomes after coronary stent implantation has already been shown. Therefore, in this study, we aimed to evaluate the effect of omega-3 supplementation on hs-CRP and 30-day major adverse cardiac events (MACE) in patients with CKD undergoing elective PCI. Methods: In this randomized trial, 80 CKD patients who were candidates for elective PCI, were randomly assigned to two groups; the first group received a single dose of omega 3 (2500 mg, 12 h before PCI) as well as the standard drug regimen of PCI and the second group received placebo plus the standard therapy (325 mg loading dose of aspirin, 600 mg loading dose of clopidogrel, and weight-adjusted intravenous heparin). Hs-CRP levels were measured at baseline and 24 h after the intervention as a primary endpoint. The secondary endpoint was the incidence of MACE over a 30 day period after PCI. Results: Omega-3 did not significantly decrease post-PCI serum level of hs-CRP; however, the overall 30-day MACE was significantly lower in the omega-3 group compared to the control group (p=0.05). Conclusion: Our results revealed the positive effect of the omega-3 supplement on decreasing 30 day MACE; hence, omega-3 may be considered as an effective adjunctive therapy to the standard drug regimen used before PCI. The evaluation of the effect of omega 3 on long-term MACE is recommended for future studies. PMID- 30276145 TI - Oleoylethanolamide Supplementation Reduces Inflammation and Oxidative Stress in Obese People: A Clinical Trial. AB - Purpose: Obesity as a serious public health problem worldwide, results in the incidence of many chronic diseases. Obesity has been recognized as a chronic low grade inflammation disorder. Altered endocannabinoid system tone is also involved in the pathogenesis of obesity. The present study aimed to investigate the effects of oleoylethanolamide supplementation on inflammatory biomarkers and oxidative stress in obese people. Methods: This randomized, double-blind, placebo controlled clinical trial was carried out on 60 healthy obese people in 2016 in Tabriz, Iran. Eligible subjects were randomly divided into intervention (received daily, two 125 mg OEA capsules) and control groups (the same amounts of starch) and treated for 8 weeks. Blood samples (5 ml) were taken in fasting state at the baseline and at the end of the study. The concentrations of MDA and TAS were measured using a spectrophotometer. A high sensitive-C reactive protein level was measured by Immunoturbidimetry assay using the commercial kit. IL-6 and TNF-alpha levels were assayed by the ELISA method. The differences between groups were assessed by ANCOVA and statistical significance was determined at p<0.05. Results: Analysis was done on 56 participants who continued intervention until the end of the study. A significant decrease in the IL-6 and TNF-alpha serum concentrations was observed in the intervention group (p<0.001). Changes in other variables were undetectable (p>0.05). Conclusion: The use of OEA as a complementary pharmacotherapy agent could be effective in improving inflammation and oxidative stress in obese people. Future studies are needed to confirm the obtained results. PMID- 30276146 TI - Evaluation of NPP1 as a Novel Biomarker of Coronary Artery Disease: A Pilot Study in Human Beings. AB - Purpose: Coronary artery calcification (CAC) is utilized as an important tool for global risk assessment of cardiovascular events in individuals with intermediate risk. Ecto phosphodiesterase/nucleotide phosphohydrolase-1(ENPP1) converts extracellular nucleotides into inorganic pyrophosphate and it is a key regulator of tissue calcification that adjusts calcification in tissues like vascular smooth muscle cells. The main purpose of this clinical study was to find out the correlation between ENPP1 serum concentration and CAC in human for the first time. Methods: In this study 83 patients (16 diabetic patients and 67 non diabetic patients) with coronary artery disease who fulfilled inclusion and exclusion criteria, entered the study. For all patients a questionnaire consisting demographic data and traditional cardiovascular risk factors were completed. Computed tomography (CT)-Angiography was carried out to determine coronary artery calcium score and enzyme-linked immunosorbent assay (ELISA) method was used for measuring ENPP1 serum concentrations. Results: There was a reverse significant correlation between ENPP1 serum concentration and total CAC score and also CAC of right coronary artery (RCA) (P<0.05) in non-diabetic patients. Conclusion: On the basis of our results, ENPP1 serum concentration may be a suitable biomarker for coronary artery disease at least in non-diabetic patients. However, more studies with higher sample size are necessary for its confirmation. PMID- 30276147 TI - Determining Abuse Deterrence Performance of Poly (ethylene oxide) Using a Factorial Design. AB - Purpose: The purpose of this study was to determine the effects of thermal processing and antioxidant formulation variables on the abuse deterrence performance of a high molecular weight poly(ethylene oxide) (PEO) polymer. Methods: A 24 factorial design with one categorical factor (antioxidant type) and three continuous factors (curing time, curing temperature, % antioxidant) was used. Abuse deterrence performance was evaluated using solution viscosity, surface melting temperature, and mechanical strength. Thermal degradation of PEO powders before compaction was also studied using DSC, FTIR spectroscopy, and viscosity analysis. Results: Our results showed that curing temperature and type of antioxidant can significantly affect the deterrence performance of PEO. The main effect plot for viscosity shows the most prominent factors affecting viscosity are curing temperature and type of antioxidant. However, curvature in the linear model obtained was not sufficient to completely describe the behavior. For surface melting temperature, butylated hydroxytoluene was associated with higher surface melting temperatures compared to ascorbic acid. Additionally, higher percent of antioxidant resulted in higher melting temperature. Particle size distribution to indicate mechanical strength showed no significant effects of tested factors. This suggests that comminution method has more prominent effect on tablet fragment size than the formulation and processing factors studied. Conclusion: While heat confers the mechanical strength to the polymer, it can diminish its physical stability and solution state viscosity. The experimental studies showed that prolonged exposure to high temperatures, even in the presence of antioxidants, can severely hamper polymer deterrence performance in both solid and solution states. PMID- 30276148 TI - The Cytotoxic and Antimigratory Activity of Brazilin-Doxorubicin on MCF-7/HER2 Cells. AB - Purpose: Breast cancer cells with overexpression of HER2 are known to be more aggressive, invasive, and resistant to chemotherapeutic agent. Brazilin, the major compound in the Caesalpinia sappan L. (CS) heartwood, has been studied for it's anticancer activity. The purpose of this study was to investigate the cytotoxic and antimigratory activity of brazilin (Bi) in combination with doxorubicin (Dox) on MCF-7/HER2 cells. Methods: Cytotoxic activities of Bi individually and in combination with Dox were examined by MTT assay. Synergistic effects were analyzed by combination index (CI). Apoptosis and cell cycle profiles were observed by using flow cytometry. Migrating and invading cells were observed by using a Boyden chamber assay. Levels of MMP2 and MMP9 activity were observed by using a gelatin zymography assay. Levels of HER2, Bcl-2, Rac1, and p120 protein expression were observed by using an immunoblotting assay. Results: The results of the MTT assay showed that Bi inhibited MCF-7/HER2 cell growth in a dose-dependent manner with an IC50 of 54 +/- 3.7 uM. Furthermore, the combination of Bi and Dox showed a synergistic effect (CI <1). Flow cytometric analysis of Bi and its combination with Dox showed cellular accumulation in the G2/M phase and induction of apoptosis through suppression of Bcl-2 protein expression. In the Boyden chamber assay, gelatin zymography, and subsequent immunoblotting assay, the combination Bi and Dox inhibited migration, possibly through downregulation of MMP9, MMP2, HER2, Rac1, and p120 protein expression. Conclusion: We conclude that Bi enhanced cytotoxic activity of Dox and inhibited migration of MCF-7/HER2 cells. Therefore, we believe that it has strong potential to be developed for the treatment of metastatic breast cancer with HER2 overexpression. PMID- 30276149 TI - Presynaptic Activity of an Isolated Fraction from Rhinella schneideri Poison. AB - Purpose: Rhinella schneideri is a toad found in many regions of the South America. The poison of the glands has cardiotoxic effect in animals and neuromuscular effects in mice and avian preparation. The purpose of this work was to identify the toxin responsible for the neuromuscular effect in avian and mice neuromuscular preparation. Methods: The methanolic extract from R. schneideri poison was fractioned by reversed phase HPLC. The purity and molecular mass were determined by LC/MS mass spectrometry. Chick biventer cervicis and mouse phrenic nerve diaphragm were used as neuromuscular preparations to identify the toxin. Results: The purification resulted in 32 fractions, which 4 of them were active in neuromuscular preparation. The toxin of fraction 20 were chosen for better reproducibility of the whole extract activity and its molecular mass was 730.6 Da. The toxin produced facilitation of the muscle contraction followed by a complete neuromuscular blockade in chick biventer cervicis preparation in 90 min without interfering with the exogenous response to ACh and KCl. The quantal content was increased from 128 +/- 13 (control) to 216 +/- 44 (after 5 min and sustained until 60 min) in the presence of the toxin. Conclusion: In conclusion, our results demonstrated that the neuromuscular action of the poison of Rhinella schneideri is a multitoxin effect. More, the present work first isolated a 730.6 Da toxin that better represent the whole poison neuromuscular effect, to which is attributed a presynaptic action in avian and mouse neuromuscular preparation. PMID- 30276150 TI - Astaxanthin-Rich Haematococcus pluvialis Algal Hepatic Modulation in D-Galactose Induced Aging in Rats: Role of Nrf2. AB - Purpose: Aging is associated with hepatic morphological and physiological deterioration due to the accumulation of endogenous and exogenous free radicals and the resultant oxidative stress. The present study aims to investigate the effect of Haematococcus pluvialis microalgae on hepatic changes associated with D galactose (D-Gal)-induced aging in rats. Methods: Aging was induced in rats by daily intraperitoneal injection of D-Gal (200 mg/kg/day) for eight consecutive weeks. D-Gal-injected rats were treated by astaxanthin (ATX)-rich H. pluvialis biomass, its carotenoid and polar fractions for two weeks. Twenty four hours after the last dose, blood samples were collected and the liver tissues were isolated for further biochemical and histopathological examinations. Results: D Gal induced aging was associated with an elevation in serum liver function parameters, hepatic oxidative stress biomarkers viz., catalase (CAT), glutathione transferase (GST) and myeloperoxidase (MPO), as well as decreased expression of nuclear factor like-2 (Nrf2). Moreover, induction of aging exhibited an elevation of hepatic inflammatory cytokine; interleukin-6 (IL-6) and its modulator; nuclear factor Kappa B (NF-KB). However, treatment of D-Gal injected rats with ATX-rich H. pluvialis restored the serum liver function parameters as well as hepatic CAT, GST and MPO levels with an elevated expression of Nrf2. Treatment with ATX-rich H. pluvialis was also accompanied with a decrease in hepatic levels of NF-KB and IL-6. Histopathological examination emphasized all the previous results. Similarly, all trans-astaxanthin showed high affinity towards Nrf2 with -7.93 kcal/mol estimated free energy of binding as well as moderate affinities towards IL-6 and NF-KB through a docking study. Conclusion: ATX-rich H. pluvialis showed beneficial effects by ameliorating the hepatic changes associated with D-Gal induced aging in rats due to its modulatory role of the Nrf2/Keap pathway. PMID- 30276151 TI - The efficacy of ultrasonography in monitoring the healing of jaw lesions. AB - Purpose: This study aimed to assess the reliability of ultrasonography (US) in comparison with cone-beam computed tomography (CBCT) as a tool for monitoring the healing of jaw lesions. Materials and Methods: Twenty-one radiolucent lesions in jaws referred to the Oral Surgery Department at our institution were selected for this study. All lesions underwent CBCT and US examinations. The anteroposterior, superoinferior, and mesiodistal dimensions of the lesions were measured on CBCT and US images before surgery and at 6 months after surgery. The dimensions were compared between the US and CBCT images. Blood-flow velocity around the lesions was measured by color Doppler before surgery and at 1 week and 6 months after surgery to assess the capability of US to show changes in blood-flow velocity around the lesion. Results: Before surgery, there were no significant differences between US and CBCT in the mesiodistal and anteroposterior dimensions, although a significant difference was found in the superoinferior dimension (P<.05). However, at 6 months after surgery, significant differences were found between US and CBCT in all dimensions, and it is likely that the US measurements more accurately reflected the extent of healing. The average blood-flow velocity increased at 1 week after surgery (5.84 cm/s) compared with the velocity before surgery (4 cm/s) (P<.05). Then, at 6 months after surgery, the blood-flow velocity significantly decreased (3.53 cm/s) compared to the velocity measured at 1 week after surgery (P<.05). Conclusion: US with color Doppler was confirmed to be a more efficient tool than CBCT for monitoring bone healing. PMID- 30276152 TI - Usefulness of shear wave elastography in the diagnosis of oral and maxillofacial diseases. AB - Purpose: To evaluate the usefulness of shear wave elastography in the diagnosis of oral and maxillofacial diseases. Materials and Methods: Ten patients with oral and maxillofacial diseases and 28 volunteers drawn from our student doctors were examined by shear wave elastography with a 14-MHz linear transducer using an Aplio 300 apparatus (Canon Medical Systems, Otawara, Japan). A statistical analysis of the shear elastic modulus (kPa) of healthy tissue (the sublingual gland, submandibular gland, anterior belly of the digastric muscle, and geniohyoid muscle) in the 28 volunteers was performed using 1-way repeated measures analysis of variance with the Tukey honest significant difference test. The maximum shear elastic modulus (kPa) of 8 patients with squamous cell carcinoma (SCC) and 2 patients with benign lesions was evaluated with the Mann Whitney U test. The analysis used a 5% significance level. Results: The mean shear elastic modulus of the sublingual gland (9.4+/-3.7 kPa) was lower than that of the geniohyoid muscle (19.2+/-9.2 kPa, P=.000) and the anterior belly of the digastric muscle (15.3+/-6.1 kPa, P=.004). The maximum shear elastic modulus of the SCCs (109.6+/-14.4 kPa) was higher than that of the benign lesions (46.4+/ 26.8 kPa, P=.044). Conclusion: Our results demonstrated the usefulness of shear wave elastography in the diagnosis of oral and maxillofacial diseases. Shear wave elastography has the potential to be an effective technique for the objective and quantitative diagnosis of oral and maxillofacial diseases. PMID- 30276153 TI - Application of portable digital radiography for dental investigations of ancient Egyptian mummies during archaeological excavations: Evaluation and discussion of the advantages and limitations of different approaches and projections. AB - Purpose: In the age of X-ray computed tomography (CT) and digital volume tomography (DVT), with their outstanding post-processing capabilities, indications for planar radiography for the study of the dentition of ancient Egyptian mummies may easily be overlooked. In this article, the advantages and limitations of different approaches and projections are discussed for planar oral and maxillofacial radiography using portable digital X-ray equipment during archaeological excavations. Furthermore, recommendations are provided regarding projections and sample positioning in this context. Materials and Methods: A total of 55 specimens, including 19 skeletonized mandibles, 14 skeletonized skulls, 18 separate mummified heads, and 4 partially preserved mummies were imaged using portable digital X-ray equipment in the course of archaeological excavations led by the University of Basel in the Valley of the Kings between 2009 and 2012. Images were evaluated by 2 authors with regard to the visibility of diagnostically relevant dental structures using a 4-point grading system (Likert scale). Results: Overall, the visibility of diagnostically relevant dental structures was rated highest by both authors on X-ray images acquired using a dental detector. The tube-shift technique in the lateral projections of mandibular dentition achieved the second-best rating, and lateral projections achieved the third-best rating. Conclusion: Conventional planar digital X-ray imaging, due to its ubiquity, remains an excellent method-and often the only practicable one-for examining the skulls and teeth of ancient Egyptian mummies under field conditions. Radiographic images of excellent diagnostic quality can be obtained, if an appropriate methodology regarding the selected projections and sample placement is followed. PMID- 30276154 TI - Influence of voxel size on cone-beam computed tomography-based detection of vertical root fractures in the presence of intracanal metallic posts. AB - Purpose: This study was performed to evaluate the influence of voxel size and the accuracy of 2 cone-beam computed tomography (CBCT) systems in the detection of vertical root fracture (VRF) in the presence of intracanal metallic posts. Materials and Methods: Thirty uniradicular extracted human teeth were selected and randomly divided into 2 groups (VRF group, n=15; and control group, n=15). The VRFs were induced by an Instron machine, and metallic posts were placed in both groups. The scans were acquired by CBCT with 4 different voxel sizes: 0.1 mm and 0.16 mm (for the Eagle 3D V-Beam system) and 0.125 mm and 0.2 mm (for the i CAT system) (protocols 1, 2, 3, and 4, respectively). Interobserver and intraobserver agreement was assessed using the Cohen kappa test. Sensitivity and specificity were evaluated and receiver operating characteristic analysis was performed. Results: The intraobserver coefficients indicated good (0.71) to very good (0.83) agreement, and the interobserver coefficients indicated moderate (0.57) to very good (0.80) agreement. In respect to the relationship between sensitivity and specificity, a statistically significant difference was found between protocols 1 (positive predictive value: 0.710, negative predictive value: 0.724) and 3 (positive predictive value: 0.727, negative predictive value: 0.632) (P<.05). The least interference due to artifact formation was observed using protocol 2. Conclusion: Protocols with a smaller voxel size and field of view seemed to favor the detection of VRF in teeth with intracanal metallic posts. PMID- 30276155 TI - Location and shape of the mandibular lingula: Comparison of skeletal class I and class III patients using panoramic radiography and cone-beam computed tomography. AB - Purpose: The aim of this study was to compare the location and the shape of the mandibular lingula in skeletal class I and III patients using panoramic radiography and cone-beam computed tomography. Materials and Methods: The sample group included 190 skeletal class I patients and 157 class III patients. The location of the lingula in relation to the deepest point of the coronoid notch was classified into 3 types using panoramic radiographs. The shapes of the lingulae were classified into nodular, triangular, truncated, or assimilated types using cone-beam computed tomographic images. The data were analyzed using the chi-square test. Results: The tips of the lingulae were at the same level as the coronoid notch in 75.3% of skeletal class I patients and above the coronoid notch in 66.6% of class III patients. The positions of the lingulae in relation to the deepest point of the coronoid notch showed statistically significant differences between class I and class III patients. The most common shape was nodular, and the least common was the assimilated shape. Although this trend was not statistically significant, the triangular shape was more frequently observed in class III patients than in class I patients. Conclusion: The locations and the shapes of the mandibular lingulae were variable. Most of the lingulae were at the same level as the coronoid notch in skeletal class I patients and above the coronoid notch in skeletal class III patients. The nodular and assimilated-shaped lingulae were the most and the least prevalent, respectively. PMID- 30276156 TI - A novel classification of anterior alveolar arch forms and alveolar bone thickness: A cone-beam computed tomography study. AB - Purpose: This study classified alveolar arch forms and evaluated differences in alveolar bone thickness among arch forms in the anterior esthetic region using cone-beam computed tomography (CBCT) images. Materials and Methods: Axial views of 113 CBCT images were assessed at the level of 3 mm below the cementoenamel junction (CEJ) of the right and left canines. The root center points of teeth in the anterior esthetic region were used as reference points. Arch forms were classified according to their transverse dimensions and the intercanine width-to depth ratio. The buccolingual alveolar bone thickness of each tooth was measured at 3 mm below the CEJ and at the mid-root level. Differences in the mean thicknesses among arch forms were analyzed. Results: Anterior maxillary arches could be classified as long narrow, short medium, long medium, and long wide arches. Significant differences in buccolingual alveolar bone thickness among the arch groups were found at both levels. The long wide arches presented the greatest bone thickness, followed by the long medium arches, while the long narrow and short medium arches were the thinnest. Conclusion: Arch forms were classified as long narrow, short medium, long medium, and long wide. The buccolingual alveolar bone thickness exhibited significant differences among the arch forms. PMID- 30276157 TI - A comparative study of cone-beam computed tomography and digital panoramic radiography for detecting pulp stones. AB - Purpose: The aim of this study was to compare cone-beam computed tomography (CBCT) and digital panoramic radiography (DPR) for the detection of pulp stones. Materials and Methods: DPR and CBCT images of 202 patients were randomly selected from the database of our department. All teeth were evaluated in sagittal, axial, and coronal sections in CBCT images. The systemic condition of patients, the presence of pulp stones, the location of the tooth, the group of teeth, and the presence and depth of caries and restorations were recorded. The presence of pulp stones in molar teeth was compared between DPR and CBCT images. Results: Pulp stones were identified in 105 (52.0%) of the 202 subjects and in 434 (7.7%) of the 5,656 teeth examined. The prevalence of pulp stones was similar between the sexes and across various tooth locations and groups of teeth (P>.05). A positive correlation was observed between age and the number of pulp stones (rho=0.277, P<.01). Pulp stones were found significantly more often in restored or carious teeth (P<.001). CBCT and DPR showed a significant difference in the detection of pulp stones (P<.001), which were seen more often on DPR than on CBCT. Conclusion: DPR, as a 2D imaging system, has inherent limitations leading to the misinterpretation of pulp stones. Restored and carious teeth should be carefully examined for the presence of pulp stones. CBCT imaging is recommended for a definitive assessment in cases where there is a suspicion of a pulp stone on DPR. PMID- 30276158 TI - The relationship between masseter muscle thickness measured by ultrasonography and facial profile in young Korean adults. AB - Purpose: The purpose of this study was to evaluate the relationship between masseter muscle thickness, facial morphology, and mandibular morphology in Korean adults using ultrasonography. Materials and Methods: Ultrasonography was used to measure the masseter muscle thickness bilaterally of 40 adults (20 males, 20 females) and was performed in the relaxed and contracted states. Facial photos and panoramic radiography were used for morphological analyses and evaluated for correlations with masseter muscle thickness. We also evaluated the correlations of age, body weight, stature, and body constitution with masseter muscle thickness. Results: In the relaxing, the masseter was 9.8+/-1.3 mm in females and 11.3+/-1.2 mm in males. In the contracted state, it was 12.4+/-1.4 mm in females and 14.7+/-1.4 mm in males. Facial photography showed that bizygomatic facial width over facial height was correlated with masseter muscle thickness in both sexes in the relaxed state, and was statistically significantly correlated with masseter muscle thickness in males in the contracted state. In panoramic radiography, correlations were found between anterior angle length and posterior angle length and masseter muscle thickness in females, and between body length and posterior angle length, between anterior angle length and body length, between ramal length and body length, and between body length and condyle length in males. Conclusion: Masseter muscle thickness was associated with facial and mandibular morphology in both sexes, and with age in males. Ultrasonography can be used effectively to measure masseter muscle thickness. PMID- 30276159 TI - Multiple intraosseous cervical pneumatocysts: A case report of a rare incidental finding on cone-beam computed tomography. AB - This report presents a case of cervical pneumatocysts as an incidental finding on cone-beam computed tomography. Pneumatocysts are gas-containing lesions of unknown etiology. They usually present in the ilium or sacrum, adjacent to the sacroiliac joint. In the literature, 21 case reports have described cervical pneumatocysts. Cervical pneumatocysts should be differentiated from other lesions, such as osteomyelitis, osteonecrosis, and neoplasms, as well as post traumatic and post-surgical cases. Computed tomography, cone-beam computed tomography, and magnetic resonance imaging are appropriate tools to diagnose cervical pneumatocysts. PMID- 30276160 TI - Radiographic study of dermal fillers in the facial area: A series of 3 cases. AB - In recent years, as interest in maintaining beauty and a youthful appearance has grown, filler procedures such as soft tissue augmentation have become more popular. These fillers are sometimes seen as radiopaque shadows on radiographic images, either due to the fillers themselves or because of secondary reactions; such findings may present a diagnostic challenge to dentists. The present report describes 3 cases of dermal fillers observed in panoramic and cone-beam computed tomographic (CBCT) images. All 3 elderly female patients had filler injected into their cheeks and chin area for cosmetic purposes decades ago. On panoramic images, multiple symmetric radiopacities were observed in the facial area; on CBCT, these calcifications were seen in the subcutaneous tissue in various shapes and with varying density. In conclusion, dentists should be aware of the imaging characteristics of dermal filler, and should be able to differentiate dermal filler from other pathological findings. PMID- 30276163 TI - Hydroxyapatite from Fish for Bone Tissue Engineering: A Promising Approach. AB - Natural or synthetic hydroxyapatite (HA) has been frequently used as implant materials for orthopaedic and dental applications, showing excellent bioactivity, adequate mechanical rigidity and structure, osteoconductivity and angiogenic properties, no toxicity, and absence of inflammatory or antigenic reactions. HA can be easily synthesized or extracted from natural sources, such as bovine bone. However, the manufacturing costs to obtain HA are high, restricting the therapy. Herein, much effort has been paid for obtaning alternative natural sources for HA. The potential of HA extracted from skeleton of animals has been investigated. The aim of this review is to exploit the potential of HA derived from fish to fulfill biological activities for bone tissue engineering. In particular, HA from fish is easy to be manufactured regarding the majority of protocols that are based on the calcination method. Furthermore, the composition and structure of HA from fish were evaluated; the biomaterial showed good biocompatibility as a result of non-cytotoxicity and handling properties, demonstrating advantages in comparison with synthetic ones. Interestingly, another huge benefit brought by HA from bone fish is its positive effect for environment since this technique considerably reduces waste. Certainly, the process of transforming fish into HA is an environmentally friendly process and stands as a good chance for reducing costs of treatment in bone repair or replacement with little impact into the environment. PMID- 30276162 TI - Bone Marrow Derived Mesenchymal Stem Cells in Addiction Related Hippocampal Damages. AB - The brain is an important organ that controls all sensory and motor actions, memory, and emotions. Each anatomical and physiological modulation in various brain centers, results in psychological, behavioral, and sensory-motor changes. Alcohol and addictive drugs such as opioids and amphetamines have been shown to exert a great impact on brain, specifically on the hippocampus. Emerging evidence has indicated that altered hippocampal neurogenesis is associated with the pathophysiology of neuropsychological disorders including addiction. The addictive drugs impair neurogenesis and undermine the function of neural stem/progenitor cells in hippocampus. This feature was claimed to be one of the underlying mechanisms of behavioral changes in patients with addiction. As the impairment of stem cells' function has been proven to be the underlying cause of pathologic neuroadaptations in the brain, the administration of stem cell populations has shown promising results for re-modulating of neuronal status in the brain and especially in the hippocampus. Among the different types of stem cells, bone marrow derived mesenchymal stem cells are the most proper candidates for stem cell therapies. In this review article, the recent studies on the effects of addictive drugs on brain neurogenesis, and also the promising potential effects of stem cells in curing addiction related hippocampal damages are discussed. PMID- 30276161 TI - Effects of Metabolites Derived From Gut Microbiota and Hosts on Pathogens. AB - Intestinal metabolites participate in various physiological processes, including energy metabolism, cell-to-cell communication, and host immunity. These metabolites mainly originate from gut microbiota and hosts. Although many host metabolites are dominant in intestines, such as free fatty acids, amino acids and vitamins, the metabolites derived from gut microbiota are also essential for intestinal homeostasis. In addition, some metabolites are only generated and released by gut microbiota, such as bacteriocins, short-chain fatty acids, and quorum-sensing autoinducers. In this review, we summarize recent studies regarding the crosstalk between pathogens and metabolites from different sources, including the influence on bacterial development and the activation/inhibition of immune responses of hosts. All of these functions would affect the colonization of and infection by pathogens. This review provides clear ideas and directions for further exploring the regulatory mechanisms and effects of metabolites on pathogens. PMID- 30276165 TI - The Growth Arrest-Specific Transcript 5 (GAS5) and Nuclear Receptor Subfamily 3 Group C Member 1 (NR3C1): Novel Markers Involved in Multiple Sclerosis. AB - Recent studies have revealed that long noncoding RNAs (lncRNAs) are connected with pathogenesis of neurodegenerative diseases. Additionally, glucocorticoids have fundamental regulatory roles on the immune system, and act as potent therapeutic compounds for autoimmune and inflammatory diseases. The long noncoding RNA growth arrest-specific 5 (GAS5) which accumulates inside the cells in response to cellular starvation/growth arrest, acts as a potent repressor of the glucocorticoid receptor (GR) through its glucocorticoid response element (GRE). The aim of the present study was to investigate the role of lncRNA GAS5 and its downstream target Nuclear Receptor Subfamily 3 Group C Member 1(NR3C1) in the pathogenesis of multiple sclerosis (MS), and to define the role of GAS5 in the regulation of NR3C1 expression. Quantitative polymerase chain reaction was performed for investigating the expression of GAS5 and NR3C1 in MS patients and healthy subjects. We found that GAS5 levels were up-regulated in the MS patients, blood compared with healthy subjects in correlation with NR3C1 expression. Our findings suggest that GAS5 may play on important role in the molecular etiology and treatment of MS. PMID- 30276166 TI - Circulatory YKL-40 & NLR: Underestimated Prognostic Indicators in Diffuse Glioma. AB - In addition to histopathological parameters, evaluation of associated hematological factors is essential for devising a sensitive prognostic scale in glioma. Increased neutrophil-lymphocyte ratio (NLR), a marker of systemic inflammatory response, has recently been associated with worse outcome in various cancers. Given that glioma progression is characterized by inflammation, aggressive angiogenesis, and invasion, increased levels of systemic human chitinase-3-like-one protein (YKL-40) have also been linked to poor prognosis. The aim of the present study was to assess the plausible association of YKL-40, NLR, and platelet count with increasing tumor grade, and evaluate their status as independent prognostic factors in terms of overall survival (OS) in treatment naive patients with diffuse glioma. Plasma levels of both biochemical markers in 72 diffuse gliomas, median age 42 years, were compared with 36 controls. Comparison of YKL-40, NLR, and PC with respect to tumor grade was found to be significant for each of the markers (P <0.0001) while an inverse significant correlation was seen for YKL-40 and NLR with OS (r = -0.4619, P <0.0001, and r = 0.5561, P < 0.0001, respectively). NLR was the best performing marker with AUC 0.9417 at 97% specificity. In addition, YKL-40 had a positive correlation with NLR (r = 0.4902, P <0.0001), indicating that expression of both markers was linked to inflammation and tumor progression as they were significantly correlated with tumor grade. Expression of YKL-40 and NLR was independently associated with worse survival (HR 1.0062, P = 0.039, and HR 1.1787, P = 0.0003, respectively), thus establishing their clinical utility as prognosticators for diffuse gliomas. PMID- 30276164 TI - Potential Use of Amniotic Membrane - Derived Scaffold for Cerebrospinal Fluid Applications. AB - Scaffolds derived from decellularized tissues provide a natural microenvironment for cell culture. Embryonic cerebrospinal fluid (e-CSF) contains factors which play vital roles in the development of the nervous system. This research was aimed to survey the effect of Wistar rat e-CSF on neural differentiation of bone marrow derived mesenchymal stem cells (BM-MSCs) cultured on the human amniotic membrane (AM). BM-MSCs were collected from femurs and tibias, and were cultured in Dulbecco's Modified Eagle's Medium. The placenta was harvested from healthy women during cesarean section and AM was acellularized using EDTA and physical scrubbing. e- CSF was harvested from rat fetuses at E17. Adequate numbers of BM MSCs were cultured on acellularized membrane, and were treated with E17 CSF for 7 days. MTT (3-(4, 5-dimethylthiazol-2-yl)-2.5-diphenyltetrazolium bromide) assay confirmed the survival and proliferation of BM-MSCs cultured on AM derived scaffold. Hematoxylin/eosin staining and scanning electron microscopy showed the morphological and the structural changes of BM-MSCs throughout the culture and treatment with e-CSF. The results of immunocytochemistry showed that microtubule associated protein 2 and beta-III tubulin were expressed in BM-MSCs cultured on acellular amnion scaffold and treated with e-CSF. Our results showed for the first time that the combination of acellular AM as a natural scaffold and e-CSF as a source of neurological factors could effectively improve the BM-MSCs cultivation and differentiation. PMID- 30276167 TI - Dysregulated Expression and Subcellular Localization of Base Excision Repair (BER) Pathway Enzymes in Gallbladder Cancer. AB - Base excision repair (BER) pathway is one of the repair systems that has an impact on radiotherapy and chemotherapy for cancer patients. The molecular pathogenesis of gallbladder cancer is not known extensively. In the present study we investigated whether the expression of AP endonuclease 1 (APE1) and DNA polymerase beta (DNA pol beta), key enzymes of BER pathway has any clinical significance with gallbladder carcinogenesis. 41 gallbladder cancer, 27 chronic cholecystitis, and 3 normal gallbladder specimens were analyzed for the expression of APE1 and DNA polymerase beta by western blotting, and subcellular localization studied by immunohistochemistry. The enzymatic activity of APE1 was also studied. The correlations with expression of the above proteins with clinical-pathological characteristics of gallbladder cancer patients were analyzed. The integrated density value ratio (relative expression) of total APE1 (37 kDa + 35 kDa variant) analyzed in the three groups of tissues, was 0.76+/ 0.03 in normal gallbladder, 0.91+/-0.08 in chronic cholecystitis, and 1.12+/-0.05 in gallbladder cancer. APE1 was found to be up-regulated in 80% of gallbladder carcinoma samples (P = 0.01). A positive trend of APE1 expression with tumor stage and lymph node positivity was observed. The enzymatic activity of APE1 was found higher in gallbladder cancer samples in comparison with chronic cholecystitis. The integrated density value ratio of DNA polymerase beta for normal gallbladder, chronic cholecystitis and gallbladder cancer tissue samples were 0.46+/-0.03, 0.7+/-0.06 and 1.33+/-0.1, respectively. DNA polymerase beta was found to be upregulated in almost all gallbladder carcinoma samples (P =0.0001), and its expression was negatively correlated with age (P=0.02). DNA polymerase beta expression showed a positive trend with tumor stage and nuclear differentiation of gallbladder cancer. It may be concluded that alteration of these BER pathway proteins may be the causal factors for carcinogenesis of gallbladder, and has targeted therapeutic potential.

PMID- 30276168 TI - Screening for Non-polyenic Antifungal Produced by Actinobacteria from Moroccan Habitats: Assessment of Antimycin A19 Production by Streptomyces albidoflavus AS25. AB - Fungal diseases are currently a serious public health problem, due to the limited number of fact-based effective principles, and the emergence of resistant strains to the polyenic antifungals. The aim of this study was to screen, for non polyenic antifungals production by Actinobacteria, and to validate the screening program by characterizingthe produced compounds.Actinobacteria isolates were tested against four clinic human-pathogenic fungi isolated from Hospital Mohammed V Rabat, Morocco. The production of non-polyenic antifungal metabolites by active isolates was investigated based on the yeast cell specificity as challenging targets, antibacterial activity, activity against resistant Candida tropicalis R2 and Pythium irregular (resistant to polyenes), inhibition of antifungal activity by the addition of exogenous ergosterol, and the UV-visible light spectrophotometric analysis of the active crude extracts.The antifungal compound produced was purified using various chromatographic techniques and the selected producing strain was identified using the polyphasic approach.Among 480 Actinobacteria isolates, 55 showed antifungal activity against all tested clinically derived fungi. After performing the screening program, 4 Actinobacteria that hadall the desired criteriawere selected. Using the polyphasic approach, the taxonomic position of the selected Streptomyces AS25, isolated from rhizospheric soil of Alyssum spinosum, showed that it belongs to Streptomyces genus with 100% partial 16S similarity with Streptomyces albidoflavus NBRC13010. On the basis of HPLC and mass spectrometry, the purified compound produced by Streptomyces AS25 was identified as a non-polyenic lactone, antimycin A19, which has been found for the first time to be produced by Streptomyces albidoflavus strain. Following the obtained results, it is important to note that our screening criteria for non-polyenic antifungals have been validated and the rhizospheric soil represents an interesting source to isolate Actinobacteria. PMID- 30276171 TI - The combined impacts of docosahexaenoic acid, endurance physical exercise, and prolonged fasting on brain function. AB - Docosahexaenoic acid (DHA), a long chain polyunsaturated fatty acid (PUFA) is highly enriched in the membrane phospholipids of the brain, neuronal tissue and retina. Accumulating evidence suggests that brain DHA is necessary for maintaining for optimal function of the cognition and the visual system, particularly the photoreceptor, the retina. Loss of brain DHA, especially during crucial brain development period, was highly associated with visual and cognitive defects. Here it would be addressed the effect of DHA on brain functions as assessed by spatial task performance using a first generation model which is similar to human nutrition case. And also, it was well known that prolonged fasting and energy restriction with endurance physical exercise stimulate cognitive function and brain function, which is caused by upregulated ketone body and upregulated brain-derived neurotropic factor (BDNF) responses. In the DHA intake or prolonged physical exercise, upregulated BDNF can activate mitochondrial biogenesis to elevate neuronal bioenergetics and enable synaptic formation. And it also can activate DNA repair in neurons. Further study on the mechanisms about the combine effects of supplementation of DHA and energy restriction on brain function is urgently needed in this area. PMID- 30276172 TI - Brief ideas about evidence-based recovery in team sports. AB - Performance in team sports is the expression of complex, dynamic, interactive, and multidimensional processes. It is now well-established that optimum recovery after practice or match is a key factor of team sport performance. During season and tournaments, improving recovery could offer an advantage for following performance. As a consequence of the professionalization of different roles in staffs, new particular roles have been developed within the team sports physician core in order to improve recovery protocols. Presently, scientific literature presents a big amount of methods used to enhance recovery based on the type of practice, time between session or competitions and equipment and/or staff accessible. These practices, usually used by teams are related to: ergonutritional, water therapy, massages techniques, stretching compression garments, sleep strategies and psychological implements. Besides, travel fatigue has been recognized by athletes and coaches as a challenging problem that could benefit from practical solutions. Nowadays, players have to play a lot of matches without enough time to recover among them, therefore the use of well-managed recovery can lead to a competitive advantage. Although the main purpose of applied sport sciences investigation is to categorize the protocols as well as providing approaches for individual recovery, the stages to recognize the most appropriate recovery plans in the field of team sports come from the analysis of the individual parameters. PMID- 30276174 TI - The effect of aerobic exercises on lipid profile of patients with human immunodeficiency virus infection undergoing highly active antiretroviral therapy: a protocol for a systematic review. AB - Patients living with human immunodeficiency virus (HIV) infection who are treated with highly active antiretroviral therapy (HAART) often experience metabolic changes that have an adverse effect on their over-all health status. This review will assess the effect of aerobic exercises on the lipid profile of individuals with HIV infection undergoing HAART. Cochrane Library, MEDLINE, CINAHL (Cumulative index to Nursing and Allied Health Literature), OVID, ProQuest, AMED (Allied and Complementary Medicine Database), PsycINFO, Web of Science Core Collection and Pedro databases will be searched until June 2018. Studies that investigated the effects of aerobic exercises on the lipid profile of HAART treated patients with HIV will be included. Two reviewers will screen all articles for eligibility and independently evaluate the risk of bias, complete quality assessment and extract data for all included articles. Homogenous quantitative outcome data will be analyzed using a random effect model of meta analysis with results presented as relative risk for dichotomous variable and standardized mean for continuous variable. Heterogeneous qualitative data will be analyzed using narrative synthesis. This systematic review will provide evidence about the effectiveness of aerobic exercises in managing HAART related dyslipidemia in patients with HIV infection and thus provide the impetus for more structured exercise interventions. PMID- 30276173 TI - Role of exercise in age-related sarcopenia. AB - Sarcopenia is an age-associated decline of skeletal muscle mass and function and is known to lead to frailty, cachexia, osteoporosis, metabolic syndromes, and death. Notwithstanding the increasing incidence of sarcopenia, the molecular and cellular mechanisms driving age-related sarcopenia are not completely understood. This article reviews current definitions of sarcopenia, its potential mechanisms, and effects of exercise on sarcopenia. The pathogenesis of age-related sarcopenia is multifactorial and includes myostatin, inflammatory cytokines, and mitochondria-derived problems. Especially, age-induced mitochondrial dysfunction triggers the production of reactive oxygen species (ROS) by mitochondria, impedes mitochondrial dynamics, interrupts mitophagy, and leads to mitochondria-mediated apoptosis. Aerobic exercise provides at least a partial solution to sarcopenia as it ameliorates mitochondria-derived problems, and resistance exercise strengthens muscle mass and function. Furthermore, combinations of these exercise types provide the benefits of both. Collectively, this review summarizes potential mechanisms of age-related sarcopenia and emphasizes the use of exercise as a therapeutic strategy, suggesting that combined exercise provides the most beneficial means of combating age-related sarcopenia. PMID- 30276175 TI - Diosgenin improves functional recovery from sciatic crushed nerve injury in rats. AB - Peripheral nerve injuries are commonly encountered clinical problem and often result in chronic pain and severe functional deficit. Diosgenin is a plant steroidal saponin and has anti-inflammatory and anticancer effects. In the present study, we investigated the effect of diosgenin on functional recovery following sciatic crushed nerve injury in rats. Walking track analysis for the functional recovery which can be quantified with the sciatic function index (SFI) was conducted. Immunohistochemistry for c-Fos in the ventrolateral periaqueductal gray (vlPAG) and paraventricular nucleus (PVN) and western blot for brain-derived neurotrophic factor (BDNF), tyrosine kinase B (TrkB), cyclooxygenase-2 (COX-2), and inducible nitric oxide synthesis (iNOS) in the sciatic nerve were performed. The right sciatic nerve was crushed for 30 sec using a surgical clip. The animals in the diosgenin-treated groups received orally once a day at the respective doses for 7 consecutive days, starting one day after surgery. Sciatic crushed nerve injury showed characteristic gait changes showing decrease of SFI value. Diosgenin treatment increased the SFI value and suppressed nerve injury-induced c Fos expression in the vlPAG and PVN. Diosgenin treatment inhibited nerve injury induced increase of BDNF, TrkB, COX-2, and iNOS expressions. It is possible that diosgenin can be used as the new therapeutic agent for pain control and functional recovery following peripheral nerve injury. PMID- 30276176 TI - High prevalence of cognitive impairment among students near mount Merapi: a case study. AB - This descriptive, cross-sectional study illustrates the high prevalence of intellectual impairment among students at the Kanisius Prontakan primary school near Mt. Merapi, one of the most active volcanic mountains in Indonesia. To determine the possible cause of these abnormal cognitive impairments, we considered and investigated the threats to society and the environment of the frequent volcanic eruptions, as well as the effects of malnutrition due to extreme poverty, in that area. The results showed that intellectual impairment and stunting were remarkably common among the students, with 10.7% of the students showing sigma of intellectual impairment and 96.4% showing signs of stunting. No noticeable chemical problems due to the volcanic activity were found in the drinking water, and no causes of such disorders other than poor nutrition due to poverty were found. Nevertheless, our results provide information on the high prevalence of health problems being experienced by children living in one of the most isolated and underdeveloped volcano mountain areas in Indonesia and draws attention to the severe effects of malnutrition on the development of those children. PMID- 30276177 TI - Effect of yoga practices on psycho-motor abilities among intellectually disabled children. AB - The children with intellectual disabilities show disorders at motor development and coordination. Hence, the objective of this study was to see the effect of yoga practices on psycho-motor abilities of intellectually disabled children. Seventy intellectually disabled children were divided into experimental group and control group. Both experimental and control group were assessed on the first day and after 12 weeks of the yoga intervention for static balance, eye hand coordination, agility and reaction time. The subjects of experimental group then underwent a training of yoga practices, for 1 hr for a total period of 12 weeks. The result of within group comparison revealed significant improvement in static balance, eye hand coordination, agility, and reaction time (P< 0.001) in subjects of yoga group however no change was observed in control group. The present study demonstrated that 12 weeks of yoga is effective in improving psycho-motor abilities of intellectually disabled children. PMID- 30276178 TI - The effects of whole body vibration exercise intervention on electroencephalogram activation and cognitive function in women with senile dementia. AB - This study conducted the Korean version of Mini-Mental State Examination (MMSE-K) to women aged 65 or older residing in Gangwon-do Province and screened those who were suspicious to have mild dementia for receiving 23 points or lower in it. For eight weeks, this author tried to verify the effects of whole body vibration exercise intervention on electroencephalogram (EEG) activation and cognitive function in women with senile dementia. According to the results, both EEG activation and cognitive function indicated statistically significant difference in terms of the interactive effect between the measuring times and groups, and there was statistically significant improvement found after the whole body vibration exercise intervention. The results of this study are meaningful because they present the possibility of whole body vibration exercise intervention to be integrated into the plan to improve life quality in patients with senile dementia by stimulating their muscle spindles and sensory organs only with the amplitude and the number of vibrations with no burden of physical activity and enhancing their EEG activation and cognitive function through the responses of the neuromuscular system. PMID- 30276179 TI - Analysis of the relationship between physical activity and metabolic syndrome risk factors in adults with intellectual disabilities. AB - The purpose of this study was to investigate the relationship between physical activities and metabolic syndrome risk factors in adults with intellectual disabilities. Seventeen adults with intellectual disabilities at a sheltered workshop wore Actical for 5 days on workdays to measure their physical activity, and blood samples were taken to measure their physical fitness factors and examine their risk factors for metabolic syndrome. The average daily physical activity was found to be 655.41+/- 129.36 kcal, and the average total physical activity over 5 days was 3,224.94+/-149.68 kcal. A positive correlation was confirmed between physical activity and muscular strength, muscular endurance, total cholesterol, low-density lipoprotein cholesterol and disability rating. Factors that predicted physical activity of adults with disabilities were disability rating (t=6.280, P<0.001) and glycated hemoglobin (t= -2.315, P<0.036), which had a 73.9% correlation (R 2=0.739) with the physical activities of adults with intellectual disabilities. In conclusion, the physical activity level of adults with intellectual disabilities was significantly lower than that of adults in similar age groups, and such low physical activity may affect their muscular strength, muscular endurance, and metabolic syndrome risk factors. Therefore, additional studies on programs to improve and enhance physical activities at sheltered workshops, where adults with intellectual disabilities are mainly supervised and active, and guidelines for continuous health management are needed. PMID- 30276180 TI - The relationship between children's flourishing and being overweight. AB - This study examined the effect of children's flourishing on the pandemic of obesity from various aspects such as age, gender, race, family, school, and community. By using a subsample of the 2011-2012 National Survey of Children's Health, the Flourishing scale analyses were performed with a total of 45,309 children. Childhood obesity was diagnosed by calculating the percentile of the body mass index. Hispanic Americans were more likely to be overweight (P<0.01). Nonoverweight children were more likely to participate in after-school activities, less likely to have sedentary behavior, more likely to miss school, to be more active, and had more of flourishing than their counterpart (P<0.01). Parent's marital and health status also positively affect children's obesity status (P<0.01). Social capital and neighbor amenities significantly affect children's weight status (P<0.01). A multifaceted understanding of the role of family, school, and community (with proving children's flourishing environment) in terms of how and what could contribute to children's obesity status is important in order to bring about positive impact. PMID- 30276181 TI - Factors that influence hospital inpatients' exercise constraints. AB - The purpose of this study is to present ways to provide more precise patient oriented services by presenting implications and promoting a better understanding of exercise constraints. This study used questionnaire survey as measurement tool for 196 hospital inpatients in 5 general hospitals in the metropolitan area (Seoul, Gyeonggi, and Incheon). The collected data were analyzed using frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, and hierarchical regression analysis using IBM SPSS Statistics ver. 23.0. The following results were obtained. First, physical activity level and health condition on their physical constraints showed that their health condition factors such as pain/discomfort and anxiety/depression had greater effects on physical constraints than other factors. Second, physical activity level, and health condition on their psychological constraints showed that health condition factors had major effects on patients' psychological constraints. Thirdly, physical activity level, and health condition on their sociocultural constraints found that anxiety/depression appeared as the key influence factor in physical and psychological constraints. PMID- 30276182 TI - Training methods and analysis of races of a top level Paralympic swimming athlete. AB - Training methods for Paralympic swimmers must take into account different pathologies, competitions classes, athlete's individual circumstances and peculiar physical adaptation mechanisms, hence general guidelines cannot be found in literature. In this study we present a training program, implemented for the physical preparation of a top level Paralympic swimmer. The athlete under study, affected by infantile cerebral palsy within a clinical picture of a spastic tetraparesis, by the end of 2016 was holder of Italian, European, world and Paralympic titles in the 400-m freestyle competition, S6 class. The training macrocycle was structured in a 3-fold periodization (three mesocycles), in view of the preparation to three international competitions. The 4-month training mesocycles prior to each competition differed substantially in terms of mileage load, intensity and recovery times. The first mesocycle was characterized by a sizeable low-intensity mileage load, the second one was shifted to lower mileage load, carried out at middle-to-high intensity levels, the third one entailed increased effort intensity, counterbalanced by lower mileage load. In all cases, recovery times were balanced to obtain optimized performance through physical adaptation to training stimuli, keeping into account the physiopatological response. Tapering phases were adjusted to maximize performance at competition. As an assessment of the effectiveness of the training method, correspondence between chronometric and technical parameters in the three competitions and the respective mesocycle training programs was found. The results of the present study may support the development of training guidelines for athletes affected by upper motor neuron lesions. PMID- 30276183 TI - The reproducibility and validity verification for body composition measuring devices using bioelectrical impedance analysis in Korean adults. AB - The purpose of this study is to examine the validity and reproducibility of impedance body fat measurement devices measuring the body composition of Korean male and female adults using three bioelectrical impedance analyzers. We compared two methods for evaluating body composition: dual energy X-ray absorptiometry (DEXA), and bioelectrical impedance analysis (BIA). Subjects were 200 healthy adult Korean males and females whose mean+/-standard deviation (range) age, standing height, body weight, and body mass index (BMI) were 44.1+/-14.5 years, 172.8+/-7.4 cm, 76.0+/-12.8 kg, and 25.4+/-3.3 kg/m2, and 44.5+/-14.7 years, 158.7+/-5.8 cm, 58.3+/-8.3 kg, and 23.2+/-3.0 kg/m2, respectively. As a result, first of all, the reproducibility of the bioelectrical impedance analyzer had very high coefficients at r=0.998, r=0.997 between men and women, respectively. The correlation coefficients among three comparisons for lean body mass (LBM) were provided the following coefficients: r=0.951 for DEXA vs. ACCUNIQ BC720, r=0.950 for DEXA vs. ACCUNIQ BC360, and r=0.946 for DEXA vs. ACCUNIQ BC380 in men. In the results for women, they also had the very high following coefficients: r=0.956 for DEXA vs. ACCUNIQ BC720, r=0.946 for DEXA vs. ACCUNIQ BC360, and r=0.957 for DEXA vs. ACCUNIQ BC380 in LBM. In conclusion, this research showed a higher correlation in terms of accuracy compared to existing BIA-based body composition measurement techniques, and the accuracy of LBM was improved with high correlation coefficients through the algorithm that was improved using the multifrequency BIA method in the ACCUNIQ BC products. PMID- 30276184 TI - Comparison of lumbar multifidus thickness and perceived exertion during graded superman exercises with or without an abdominal drawing-in maneuver in young adults. AB - The present study aimed to investigate lumbar multifidus (LM) thickness and perceived exertion during graded superman exercises (GSE) or GSE with an abdominal drawing-in maneuver (GSE-AD) in young adults. Twelve young adult males and females, who were informed of the purpose and procedures of this study and then gave their voluntary consent to participate, were included in this study. All subjects randomly performed three GSE and GSE-AD over 3 days. Ultrasonography was used to measure the LM thickness to the left and right of the L5 region. Additionally, the issue of whole-body fatigue felt by the subject while performing the GSE or GSE-AD was measured using the Borg scale. The intrarater reliability of the LM measurement was found to be intraclass correlation coefficient (ICC[3,1])=0.97 (0.87-0.99) at resting and ICC(3,1)=0.94 (0.78-0.99) at contraction. Both the left and right LM showed significantly higher contraction during the grade 3 GSE (P< 0.05). The whole-body fatigue was significantly greater following GSE 2 and 3 than following GSE-AD 2 and 3 (P<0.05). In particular, GSE-AD had a significantly lower Borg score compared to GSE (P<0.05) and did not show any significant difference in muscle thickness (P>0.05). It is recommended that the abdominal drawing-in maneuver be applied with grade 3 GSE to enhance stability and reduce spinal fatigue. PMID- 30276185 TI - Evaluation of nocturnal heart rate variability for strenuous exercise day using wearable photoelectric pulse wave sensor. AB - In this study, we examined whether or not the strenuous exercise in the evening change nocturnal heart rate variability (HRV) and recovers. Subjects were 8 healthy men belonging to the mature futsal team (age: 35+/-3 years) and Futsal was held from 5:00 p.m. to 6:30 p.m. on Sunday. Pulse waves during sleeping were measured at home on exercise day and on control day. The mean pulse interval (MPI), standard deviation pulse interval (SDPI), low frequency component (LF, 0.04-0.15 Hz), high frequency component (HF, 0.15-0.45 Hz) and the ratio of LF to HF (LF/HF) were calculated from pulse interval time series every 30 min. As a result, MPI, SDPI, LF, HF of exercise day were significantly lower than control day (P<0.0001). LF/HF of exercise day was significantly higher than control day (P<0.05). Regarding change of HRV for every 30 min, MPI (P<0.05), SDPI (P=0.0003), LF (P=0.0038), HF (P<0.05) were observed significant changes. MPI and HF before wake-up did not reach the level of control day. It is thought that strenuous exercise in the evening promotes sympathetic nervous activity during night sleep and suggesting that pulse rate and HRV have not recovered by the wake up time. PMID- 30276186 TI - The influence of ovulation on postural stability (Biodex Balance System) in young female. AB - The purpose of this study was to examine the influence of ovulation (OV) on dynamic balance in young female. Thirty-two eumenorrheic healthy women participated in Biodex Balance System (BBS) test for postural stability and a limit of stability menstrual cycle. BBS was tested in the menses (MS), OV, and luteal phase (LP). The limits of stabilities (total, forward-left, forward-right, backward-left, and backward-right) were significantly higher in the OV (total, 61.44+/-14.77; forward-left, 67.50+/- 15.17; forward-right, 69.50+/-14.43; backward-left, 64.00+/-20.32; and back-ward-right, 69.06+/-13.59) than in the MS (total, 55.44+/-14.63; forward-left, 60.00+/-15.98; forward-right, 62.17+/-9.78; backward-left, 57.83+/-19.09; and backward-right, 57.28+/-13.73). Furthermore, the LP (65.11+/-13.79) was a significantly higher limit of stability than MS (57.28+/-13.73) during back-ward-right. The present study showed that estrogen negatively influences postural stability. The postural sway in limits of stabilities (total, forward-left, forward-right, backward-left, and backward right) were significantly the greatest in the OV. Since there is a different postural stability between MS, OV, and LP, this should be taken into account when devising training programs to avoid risk factor of fall and joint injury. PMID- 30276187 TI - Incidence analysis of axial and lower extremity deviations based on the physical characteristics between domestic and foreign college students. AB - This research was performed to identify the incidence and to determine the effects of risk factors of axial and lower extremity deformities. One hundred forty-seven domestic college students (102 males and 45 females) and 72 foreign students (33 males and 39 females) were subjects in this study. Data collecting was performed by questionnaire and visual postural evaluation. For backpack shoulder dominance, higher incidences of genu varus (P=0.043) and lower incidence of leg length discrepancy (LLD) (P=0.001) were found in both shoulder carrier, while the incidence of lordosis was higher in left (P=0.001) and both (P=0.012) carrier in domestic students. The incidence of genu varus (P=0.022) and scoliosis (P=0.002) were significantly lower in both shoulder carrier in foreign students. For dominant arm, the incidence of forward head (P=0.001) and of lordosis (P=0.029) were significantly higher in left handedness both in domestic students and in foreign students. As the body mass index increases, the incidence of protruding abdomen (P=0.001) and lordosis (P=0.009) showed significant increase, but, the incidence of kyphosis (P=0.022) and scoliosis (P=0.001) decreased in domestic students, and same tendency for lordosis (P=0.001) and for scoliosis (P=0.001) in foreign students. As a whole, in domestic students, female students revealed significantly high (P=0.004) incidence of genu recurvatum compared to significantly low (P=0.022) incidence of LLD. However, no significant incidence difference found in foreign students. Male students showed significantly low incidence (P=0.001) of LLD and high incidence (P=0.014) of lordosis. In foreign students, female students also showed significantly low incidence (P=0.032) of LLD in foreign students compared to their counterparts. PMID- 30276188 TI - Effects of diaphragm and deep abdominal muscle exercise on walking and balance ability in patients with hemiplegia due to stroke. AB - The aim of this study was to investigate the effects of diaphragm and deep abdominal muscle exercise (DDAME) on walking ability (WA) and balance ability (BA) in subjects with hemiplegia due to stroke. Study subjects consisted of twenty patients diagnosed with hemiplegia due to stroke. They were randomized into a control group (CG) (n=10) that performed traditional exercise and an experimental group (EG) (n=10) that performed DDAME. The WA was measured using the 10-m walking test (10MWT) and 6-min walk test (6MWT). The BA was measured using the Timed Up and Go test (TUG) and Berg's balance scale (BBS). Paired t test was performed to compare differences within the groups before and after intervention. The analysis of covariance was performed to compare the differences between the EG and CG. The level of significance was set at alpha=0.05. Within group changes in 10MWT and 6MWT were significantly different in both the EG (P<0.05) and CG (P<0.05). There was significantly more improvement in the 10MWT and 6MWT in the EG than in the CG (P<0.05). Within-group changes in TUG and BBS were significantly different in both the EG (P<0.05) and the CG (P<0.05). There was significantly more improvement in TUG and BBS in the EG than in the CG (P<0.05). DDAME program, with diaphragm and inspiratory muscle strengthening exercises, is needed for patients experiencing difficulty in WA, BA, trunk asymmetry, abnormal alignment, mobility of trunk muscles, power, or endurance decline. PMID- 30276189 TI - Functional resistance training can increase strength, knee torque ratio, and functional performance in elderly women. AB - Functional resistance training can increase strength, knee torque ratio, and functional performance in elderly women. The aim of the present study was to understand the effects of closed kinetic chain exercises with constant load on muscular strength, the knee torque conventional ratio (hamstring:quadriceps - H:Q), and functional capacity in the elderly. Nine untrained healthy elderly women participated in experimental resistance training. Ten-repetition maximum (10RM) for the deadlift, isokinetic maximum voluntary concentric contraction, and functional capacity were assessed before and after the 7-week resistance-training program. Magnitude based inference analysis was used to examine the differences in muscle strength and functional performance. Therefore, the smallest worthwhile change was calculated and 90% confidence intervals were also determined to characterize muscle strength and functional performance. The analysis demonstrated an increase in the deadlift and knee flexor torque (60o/sec) after the experimental intervention. Furthermore, stair ascent, knee extensor torque (120o/sec), knee flexor torque (120o/sec), and knee ratio (60o/sec) also presented a positive effect in the same training period. Conversely, knee extensor torque (60o/sec), and knee ratio (120o/sec) did not show conclusive responses. In conclusion, resistance training with functional closed kinetic chain exercises and constant volume load (i.e., 65% of 1-repetition maximum) can increase deadlift 10RM, isokinetic concentric torque, the conventional H:Q ratio, and stair ascent performance in elderly women. PMID- 30276190 TI - The effects of combined aerobic and resistance training on inflammatory markers in obese men. AB - It is important to treat obesity and the related noncommunicable diseases. The main objective of this study is the effect of different training types on inflammatory and immune markers in obesity. Seventeen obese men with body mass index (BMI)>=26 kg/m2 were randomly divided into two groups: aerobic training group (AT; n=9) and combined aerobic and resistance training group (CT; n=8). Body composition (weight, BMI, %body fat), factors of physical performance (one repetition maximum [1RM], maximal oxygen uptake [VO2max]), inflammatory markers (interleukin-6, tumor necrosis factor-alpha [TNF-alpha]), immune markers (leukocyte, natural killer cell) were analyzed before and after 8-week training. Body composition (weight, BMI, and %body fat) was significantly reduced after training in both the AT and CT groups (P<0.05). As a result of training, VO2max of all training groups was increased and 1RM of CT group was partially improved. In particular, the inflammatory marker, TNF-alpha was significantly reduced (P<0.05) and the change was correlated with %body fat in the posttraining CT group. In this study, we found that combined training for 8 weeks improved physical fitness, body composition, and inflammation. It is suggested that restoring obesity through combined training of aerobic and resistance exercise is related to changes in serum TNF-alpha levels. PMID- 30276191 TI - The effects of circuit training on the indexes of sarcopenia and the risk factors of metabolic syndrome in aged obese women. AB - The purpose of this study is to examine the effects of circuit training on the indexes of sarcopenia and the risk factors of metabolic syndrome in aged obese women. To address the goal, this author selected aged women whose body mass index was higher than 25.0 kg/m2 visiting the welfare center for the aged located in Gangwon-do Province and measured the indexes of sarcopenia and the risk factors of metabolic syndrome after circuit training. Through that, this study has gained following results. First, after circuit training, aged obese women's indexes of sarcopenia indicated statistically significant difference in terms of interaction between the measuring times and groups. Second, after circuit training, aged obese women's risk factors of metabolic syndrome (systolic blood pressure, diastolic blood pressure, fasting blood sugar, triglycerides, high-density lipoprotein-cholesterol, and waist circumference) showed statistically significant difference in terms of interaction between the measuring times and groups. To sum up the above results, circuit training improves aged obese women's indexes of sarcopenia and risk factors of metabolic syndrome positively, which means circuit training is found to be effective. Therefore, the circuit training intervention enhances aged obese women's muscular and metabolic functions positively. As it helps prevent and manage the risk factors of sarcopenia and metabolic syndrome resulted from aging, it will elevate life quality in senescence. PMID- 30276192 TI - Oral adenosine 5'-triphosphate supplementation improved hemodynamic and autonomic parameters after exercise in hypertensive women. AB - The aim of this study was to verify the autonomic modulation and blood pressure after adenosine-5'-triphosphate (ATP) supplementation associated to acute aerobic exercise in hypertensive women. Eleven hypertensive women (age, 61.8+/-5.0 years) completed a randomized, double blind trial: ATP supplement condition (ATP=400 mg) or placebo. After 30 min of supplementation or placebo intake, the subjects performed 30 min of aerobic exercise (70%-75% of maximum heart rate). The autonomic modulation was assessed by heart rate variability during rest and recovery (postexercise until 30 min of recovery), the square root of the mean squared difference between adjacent RR intervals (RMSSD), standard deviation of successive values (SDNN), low frequency (LF) and high frequency (HF) were measured. The blood pressure (systolic blood pressure [SBP] and diastolic blood pressure, mmHg) were recorded at rest, immediately postexercise, post-10, post 20, and post-30 min after exercise. For RMSSD, there was statistically significant difference during recovery, with higher RMSSD for ATP compared to placebo (rest=16.4+/-8.5 vs. placebo=11.6+/-4.0; ATP=18.5+/-9.7 msec; P=0.020). When analyzing the delta (recovery minus rest), the RMSSD (ATP=2.1+/- 7.2 msec vs. placebo=-4.7+/-7.5 msec; P=0.009), LF (ATP=-19.8+/-122.7 vs. placebo=-94.1+/ 200.2 msec2; P=0.02), and SDNN (ATP=-2.8+/-12.2 msec vs. placebo=-10.6+/-10.5 msec; P=0.010) were higher for ATP than placebo. Furthermore, there was a greater postexercise hypotension at 20 min for ATP (SBP: ATP=-13.2+/-8.4 mmHg vs. placebo=-6.1+/-9.9 mmHg; P=0.006). Acute ATP supplementation promoted greater postexercise hypotension for systolic blood pressure and induced faster recovery of heart rate variability in hypertensive women. PMID- 30276193 TI - Functional capacity and ventilatory efficiency are preserved in well-controlled people living with human immunodeficiency virus/acquired immunodeficiency syndrome. AB - To verify and compare the responses of the cardiopulmonary variables to the incremental test in physically inactive people living with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) (PLWHA) with well controlled disease and physically inactive healthy subjects (non-HIV/AIDS). Participants performed a cardiopulmonary exercise test (CPX) on a treadmill. Data were analyzed using the Mann-Whitney test and Spearman correlation. Nine PLWHA (5 women) and 9 non-HIV/AIDS gender and activity level-matched controls were included in the data analysis. Data are expressed in median (range). No difference was shown in the PLWHA group when compared to the control group in functional capacity (peak oxygen consumption [VO2peak]: 29.9 (20.9-36.4) mL/kg/min vs. 32.2 (24.5-39.4) mL/kg/min) and ventilatory efficiency (oxygen uptake efficiency slope [OUES]: 2,058 [1,474-3,204] vs. 2,612 [1,383-4,119]; minute ventilation carbon dioxide production slope: 27.4 [22.5-33.6] vs. 27.5 [20.4-38.1]). The results are also similar to maximal heart rate, oxygen pulse, gas exchange threshold, respiratory compensation point, heart rate recovery, and half-time of VO2peak recovery. OUES had a strong correlation with VO2peak in the PLWHA group (r s =0.70, P=0.04) and control group (r s =0.78, P=0.02). The results of this study indicate that functional capacity and ventilatory efficiency in PLWHA with well-controlled disease are preserved and are not different from sedentary subjects. In this sense, when CPX is unavailable, the aerobic assessment and prescription could be based on simpler procedures used in healthy subjects. PMID- 30276194 TI - Blood pressure responses after resistance exercise session in women living with human immunodeficiency virus/acquired immunodeficiency syndrome. AB - The aim of this study was to verify blood pressure (BP) responses after a single resistance exercise session in women with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). Twelve patients underwent a resisted exercise session. BP, heart rate, and rate pressure product were evaluated before and during 120 min after the session. Mean cardiovascular values before and after the session were similar (P>0.05). Analysis of the individual data revealed that for 120 min after exercise, 5 and 4 patients presented a reduction in systolic and diastolic BP of >=4 mmHg, respectively. The clinical characteristics of the patients appear to influence BP responses after exercise. Individual data showed that some of the HIV+ women demonstrated a clinically significant decrease in BP. Although a single resistance exercise session does not decrease BP in women with HIV/AIDS, individual data present heterogeneity and individual characteristics seem to influence BP reduction after a single session of resistance exercises. PMID- 30276195 TI - Duration of wrist immobilization is associated with shoulder pain in patients with after wrist immobilization: an observational study. AB - The main goal of this study was to determinate the extent of the relationship between shoulder pain and time of wrist and thumb immobilization required after injury. One hundred twenty-three consecutive subjects presenting to the practice of different Orthopedic Specialist hospitals with a diagnosis of distal radius or scaphoid fracture that required wrist and thumb immobilization were screened for eligibility criteria. Upper extremity pain and the need for shoulder rehabilitation were assessed using the visual analogue scale (VAS) at baseline after immobilization period (T0) 1- and 3-month follow-up (1-FU/2-FU). More than 35% patients had shoulder pain (VAS>40 mm) after immobilization of the wrist. Shoulder pain intensity after immobilization and at follow-up (1 and 3 months) was strongly correlated with the duration of the immobilization. Immobilization for 3.5 weeks or longer was the strongest predictor for the need of subsequent shoulder rehabilitation. An increased the time of immobilization of the wrist is associated with an increase in shoulder pain and need for shoulder rehabilitation in patients after wrist fracture. PMID- 30276196 TI - Effect of slipper wearing and carrying positions of infant on dynamic stability and kinetic variable during level walking. AB - Recently though various hip seats for carrying infant of women was designed and developed, then, wearing slipper may restrain the movement of bare foot. The study was undertaken to investigate the dynamic stability and kinetic variables according to between position of carrying infant and wearing slipper. Adult female (n=10) and under one year age of infant (n=10) participated in the study. Extrapolated center of mass, center of pressure, ground reaction force (GRF), and leg stiffness of gait characteristics using 3-dimensional cinematography and GRF were analyzed. Dynamic stability according to position of carrying infant and wearing slipper was not significant. While when carried an infant against normal gait showed significant difference in breaking force, leg stiffness and loading rate (P<0.001). Of which breaking force and vertical impulse were more increased when the back-carried against fore-carried of trunk. Thus it resulted in transformation on types of impulse transfer to leg and COG of women's carrying infant, which may be strategy for securing a dynamic stability. Therefore experts related with exercise rehabilitation should understand sufficiently on gait characteristics of women with diseases on muscular-skeletal system and perform effective rehabilitation and treatment. PMID- 30276197 TI - The Effectiveness of Antiviral Treatments for Patients with HBeAg-Positive Chronic Hepatitis B: A Bayesian Network Analysis. AB - This network analysis is to determine the most effective treatment in HBeAg positive patients. PubMed databases were searched for randomized controlled trials. Bayesian network meta-analysis was used to calculate the pairwise hazard ratios, 95% credible intervals, and ranking of surrogate outcomes. 9 studies were identified. The results show that NA add-on PEG IFN might be a better antiviral approach for HBeAg-positive patients in end point of treatment, with a comparable results of nucleoside/nucleotide analogs (NA), PEG IFN, PEG IFN add-on NA, PEG IFN combined NA, and PEG IFN combined placebo in alanine aminotransferase (ALT) normalization and HBV DNA undetectable. Cumulative probabilities of being the most efficacious treatment were NA add-on PEG IFN (30%) for HBeAg loss. The second efficacious (23%) is HBeAg seroconversion. This network analysis shows that NA add-on PEG IFN might be a better antiviral approach for HBeAg-positive patients in end point of treatment. But the long-term efficiency should be further determined. PMID- 30276198 TI - Green Light-Emitting Devices Based on Perovskite CsPbBr3 Quantum Dots. AB - In this paper, high quality green-emitting CsPbBr3 quantum dots (QDs) are successfully synthesized by hot-injection method. Different injection temperatures are tested to optimize the synthesis conditions. High brightness with the photoluminescence (PL) quantum yields (QYs) up to 90% and narrow size distribution with the full width at half-maximum (FWHM) of 18.5 nm are obtained under the optimized conditions. Green light emitting diodes (LEDs) based on the CsPbBr3 QDs are successfully demonstrated by combining solution method with vapor deposition method. Composite films of poly[9,9-dioctylfluorene-co- N-[4-(3 methylpropyl)]-diphenylamine] (TFB) and bathocuproine (BCP) layers are chosen as the hole-transporting and the electron-transporting layers, respectively. The highly bright green QD-based light-emitting devices (QLEDs) showing maximum luminance up to 46,000 cd/m2 with a low turn on voltage of 2.3 V, and peak external quantum efficiency (EQE) of 5.7%, corresponding to 19.9 cd/A in luminance efficiency. These devices also show high color purity for electroluminescence (EL) with FWHM <20 nm, and no redshift and broadening with increasing voltage as well as a spectral match between PL and EL. PMID- 30276199 TI - Medial Hypoxia and Adventitial Vasa Vasorum Remodeling in Human Ascending Aortic Aneurysm. AB - Human ascending aortic aneurysms characteristically exhibit cystic medial degeneration of the aortic wall encompassing elastin degeneration, proteoglycan accumulation and smooth muscle cell loss. Most studies have focused on the aortic media and there is a limited understanding of the importance of the adventitial layer in the setting of human aneurysmal disease. We recently demonstrated that the adventitial ECM contains key angiogenic factors that are downregulated in aneurysmal aortic specimens. In this study, we investigated the adventitial microvascular network (vasa vasorum) of aneurysmal aortic specimens of different etiology and hypothesized that the vasa vasorum is disrupted in patients with ascending aortic aneurysm. Morphometric analyses of hematoxylin and eosin-stained human aortic cross-sections revealed evidence of vasa vasorum remodeling in aneurysmal specimens, including reduced density of vessels, increased lumen area and thickening of smooth muscle actin-positive layers. These alterations were inconsistently observed in specimens of bicuspid aortic valve (BAV)-associated aortopathy, while vasa vasorum remodeling was typically observed in aneurysms arising in patients with the morphologically normal tricuspid aortic valve (TAV). Gene expression of hypoxia-inducible factor 1alpha and its downstream targets, metallothionein 1A and the pro-angiogenic factor vascular endothelial growth factor, were down-regulated in the adventitia of aneurysmal specimens when compared with non-aneurysmal specimens, while the level of the anti-angiogenic factor thrombospondin-1 was elevated. Immunodetection of glucose transporter 1 (GLUT1), a marker of chronic tissue hypoxia, was minimal in non-aneurysmal medial specimens, and locally accumulated within regions of elastin degeneration, particularly in TAV-associated aneurysms. Quantification of GLUT1 revealed elevated levels in the aortic media of TAV-associated aneurysms when compared to non-aneurysmal counterparts. We detected evidence of chronic inflammation as infiltration of lymphoplasmacytic cells in aneurysmal specimens, with a higher prevalence of lymphoplasmacytic infiltrates in aneurysmal specimens from patients with TAV compared to that of patients with BAV. These data highlight differences in vasa vasorum remodeling and associated medial chronic hypoxia markers between aneurysms of different etiology. These aberrations could contribute to malnourishment of the aortic media and could conceivably participate in the pathogenesis of thoracic aortic aneurysm. PMID- 30276201 TI - Effect of Fungal Solid-State Fermented Product in Broiler Chicken Nutrition on Quality and Safety of Produced Breast Meat. AB - The aim of this work was to analyse the effect of addition of 10% (w/w) fermented bioproduct into commercial broiler feed on fatty acid profile, lipid oxidative stability, and sensory properties of chicken breast meat. The fermented bioproduct was prepared by fermentation of cornmeal by filamentous fungi Umbelopsis isabellina CCF 2412 in solid-state fermentation (SSF) process and the final bioproduct was enriched with gamma-linolenic acid and beta-carotene. In the experiment, 80 pieces of 1-day-old chickens COBB 500 were used. Half of them (control group) were fed only with commercial feed. Chickens of the experimental group were fed with commercial feed, and, from the 11th day of age until the time of slaughter (39th day), 10% of commercial feed was replaced with fermented bioproduct. Application of fermented bioproduct into commercial feed mixture positively influenced profile of fatty acids in breast meat. The amount of gamma linolenic, alpha-linolenic, and oleic acids in fat of breast muscles was increased and n-6/n-3 ratio was significantly decreased. Profile and content of PUFAs did not change after thermal treatment of meat. Oxidative stability of fat and sensory properties of the meat during the storage (4 degrees C, 7 days) of meat were not affected by fermented bioproduct. PMID- 30276203 TI - Microarray-Based Detection and Clinical Evaluation for Helicobacter pylori Resistance to Clarithromycin or Levofloxacin and the Genotype of CYP2C19 in 1083 Patients. AB - Background. Helicobacter pylori (H. pylori) is one of the most frequent and persistent bacterial infections that affect nearly half of the world's population. Antibiotic resistance is a constantly evolving process and local surveillance of antibiotic resistance is warranted to guide clinicians in their choice of therapy. The aim of this study was to establish a microarray-based detection to identify H. pylori infection, clarithromycin and levofloxacin susceptibility, and CYP2C19 genetic polymorphism and guide to potential choice of proton pump inhibitor (PPI), antibiotic administration for tailored H. pylori eradication therapy. Methods. By analyzing the sequence of human genomic CYP2C19*2 and CYP2C19*3 and mutations within the 23S rRNA and gyrA gene regions conferring clarithromycin and levofloxacin resistance, respectively, we developed a microarray for individual therapy detection of H. pylori infection. Plasmids were established as positive or limit of detection (LOD) reference materials. The specificity and sensitivity of the microarray had been performed. And a total of 1083 gastric biopsy samples were tested and the Kappa value had been calculated between the array and Sanger sequencing. We also analyzed the resistance to clarithromycin and levofloxacin in China, as well as the CYP2C19 polymorphisms. Results. The LOD of detecting H. pylori was 103 CFU/mL and human genome DNA was 2 ng/MUL. The detection results of 1083 gastric biopsy samples showed that 691 (63.80%) were H. pylori positive, of which 266 (38.49%) were resistant to clarithromycin, 192 (27.79%) were resistant to levofloxacin, and 61 (8.83%) were resistant to both of them. For the type of CYP2C19 polymorphism, 412 (38.04%) were homozygous fast type (HomEM), 574 (53%) were heterozygous EM (HetEM), and 97 (8.96%) were poor metabolizer (PM). Conclusions. The proposed microarray-based detection has high specificity, sensitivity, and reproducibility for detecting the resistance of clarithromycin or levofloxacin as well as CYP2C19 polymorphism, which may help to improve the clinical eradication rate of H. pylori. PMID- 30276204 TI - Biochemical Changes and Biological Origin of Key Odor Compound Generations in Pig Slurry during Indoor Storage Periods: A Pyrosequencing Approach. AB - Production of odors is a complex process. Many bacterial species are involved in the production of an extensive array of key odor compounds in stored pig slurry. Understanding of basic microbial communities and their role during storage periods is an essential way to control and prevent the odors generations. In this aspect, the pig slurry samples were taken directly from deep pits of finisher pig building every two weeks, their biochemical changes were analysed, and the indigenous bacterial communities that involve in offensive odor producing compounds were identified. The SCFA, BCFA, phenols, and indoles levels altered drastically in the slurry during storage periods. The COD, BOD, SS, P2O5, TKN, and NH4-N were increased in the stored slurry. Bacterial ecology indicates Firmicutes and Bacteroidetes phyla were dominantly found in pig slurry. Odorants produced in pig slurry were correlated with bacterial communities. Phenols, indoles, SCFA, and BCFA productions were positively correlated with bacteria species which comes under phyla of Firmicutes and Bacteroidetes. It seems that bacterial species under Firmicutes and Bacteroidetes phyla play an important role in the offensive odor compounds production. Taken together, the prevention of these phyla bacterial growth and early discharge of pig slurry might reduce the offensive odor production. PMID- 30276202 TI - Fractional Flow Reserve Derived from Coronary Computed Tomography Angiography Datasets: The Next Frontier in Noninvasive Assessment of Coronary Artery Disease. AB - Fractional flow reserve (FFR) derived from coronary CTA datasets (FFRCT) is a major advance in cardiovascular imaging that provides critical information to the Heart Team without exposing the patient to excessive risk. Previously, invasive FFR measurements obtained during a cardiac catheterization have been demonstrated to reduce contrast use, number of stents, and cost of care and improve outcomes. However, there are barriers to routine use of FFR in the cardiac catheterization suite. FFRCT values are obtained using resting 3D coronary CTA images using computational fluid dynamics. Several multicenter clinical trials have demonstrated the diagnostic superiority of FFRCT over traditional coronary CTA for the diagnosis of functionally significant coronary artery disease. This review provides a background of FFR, technical aspects of FFRCT, clinical applications and interpretation of FFRCT values, clinical trial data, and future directions of the technology. PMID- 30276205 TI - Application of 3D-Printed Personalized Guide in Arthroscopic Ankle Arthrodesis. AB - Objective: To accurately drill the Kirschner wire with the help of the 3D-printed personalized guide and to evaluate the feasibility of the 3D technology as well as the outcome of the surgery. Methods: Patients' DICM data of ankle via CT examinations were introduced into the MIMICS software to design the personalized guides. Two 2mm Kirschner wires were drilled with the help of the guides; the C arm fluoroscopy was used to confirm the position of the wires before applying the cannulated screws. The patients who underwent ankle arthrodesis were divided into two groups. The experimental group adopted the 3D-printed personalized guides, while the control group received traditional method, i.e., drilling the Kirschner wires according to the surgeon's previous experience. The times of completing drilling the Kirschner wires to correct position were compared between the two groups. Regular follow-ups were conducted to statistically analyze the differences in the ankle fusion time and AOFAS scores between the two groups. Results: 3D-printed personalized guides were successfully prepared. A total of 29 patients were enrolled, 15 in the experimental group and 14 in the control group. It took 2.2 +/- 0.8 minutes to drill the Kirschner wires to correct position in the experimental group and 4.5 +/- 1.6 minutes in the control group (p=0.001). No obvious complications occurred in the two groups during and after surgery. Postoperative radiographs confirmed bony fusion in all cases. There were no significant differences in the fusion time (p=0.82) and AOFAS scores at 1 year postoperatively between the two groups (p=0.55). Conclusions: The application of 3D-printed personalized guide in assisting the accurate drilling of Kirschner wire in ankle arthrodesis can shorten the operation time and reduce the intraoperative radiation. This technique does not affect the surgical outcome. Trial Registration Number: This study is registered on www.clinicaltrials.gov with NCT03626935. PMID- 30276206 TI - The Effectiveness of Remineralizing Agents on Dentinal Permeability. AB - The effectiveness of remineralizing agents in reducing dentine permeability by tubule occlusion using fluid filtration device functioning at 100 cmH2O (1.4 psi) pressure and SEM/EDX analysis were evaluated and compared. Seventy (n = 70) dentine discs of 1+/-0.2 mm width were prepared from sound permanent human molars. Fifty (n = 50) dentine discs were randomly divided into 5 groups (n = 10): Group 1: GC Tooth Mousse Plus (Recaldent GC Corporation Tokyo, Japan), Group 2: ClinproTM White Varnish (3M ESPE, USA), Group 3: Duraphat(r) Varnish (Pharbil Waltrop GmbH, Germany), Group 4: Colgate Sensitive Pro-ReliefTM dentifrice (Colgate Palmolive, Thailand), and Group 5: BiodentineTM (Septodont/UK). Dentine permeability was measured after treatment application at 10 minutes, artificial saliva immersion at 7 days, and citric acid challenge for 3 minutes. Data were analyzed by two-way repeated measures ANOVA. Dentine specimens (n = 20) were used for SEM/EDX analyses to obtain qualitative results on dentine morphology and surface deposits. Each treatment agent significantly reduced dentine permeability immediately after treatment application and created precipitates on treated dentine surfaces. All agents increased permeability values after 7 days of artificial saliva immersion except Clinpro White Varnish and Biodentine. Clinpro White Varnish exhibited significant resistance to acid challenge compared to others. Colgate Sensitive Pro-Relief dentifrice has a dual mechanism of action in reducing the dentine sensitivity. PMID- 30276200 TI - Cisplatin-Induced Rodent Model of Kidney Injury: Characteristics and Challenges. AB - Cisplatin is an antitumor drug used in the treatment of a wide variety of malignancies. However, its primary dose-limiting side effect is kidney injury, which is a major clinical concern. To help understand mechanisms involved in the development of kidney injury, cisplatin rodent model has been developed. Given the complex pathogenesis of kidney injury, which involves both local events in the kidney and interconnected and interdependent systemic effects in the body, cisplatin rodent model is indispensable in the investigation of underlying mechanisms and potential treatment strategies of both acute and chronic kidney injury. Cisplatin rodent model is well appreciated and widely used model due to its simplicity. It has many similarities to human cisplatin nephrotoxicity, which are mentioned in the paper. In spite of its simplicity and wide applicability, there are also traps that need to be taken into account when using cisplatin model. The present paper is aimed at giving a concise insight into the complex characteristics of cisplatin rodent model and heterogeneity of cisplatin dosage regimens as well as outlining factors that can severely influence the outcome of the model and the study. Challenges for future research are also mentioned. PMID- 30276208 TI - A Shallow Angle Short-Axis Out-of-Plane Approach Reduces the Rate of Posterior Wall Injuries in Central Venous Catheterization: A Simulation Study. AB - The short-axis out-of-plane approach (SAX-OOP) is commonly used in ultrasound guided internal jugular vein catheterization. However, this approach has a risk of posterior vein wall injuries. The authors hypothesized that a shallow angle of approach may reduce the rate of posterior wall injuries compared with the conventional steep angle approach. The present study aimed to evaluate whether a difference in the angle of approach of the needle affects the rate of posterior wall injuries. The present study was a randomized crossover-controlled trial involving 40 medical residents, conducted in the clinical training center at a hospital with a residency program. The primary outcome measure was the rate of posterior vessel wall injuries. Subjects received a didactic lecture during which the instructors taught three SAX-OOP techniques including the conventional free hand method (procedure C), a needle navigation system (procedure N), and a shallow puncture angle using a guidance system (procedure S). Participants were trained in these approaches under supervision and each technique tested in a simulation environment. Thirty-four of 40 residents had no previous experience with central venous catheterization and were included in the final analysis. The rate of posterior vessel wall injuries in procedure S (9%) was significantly lower than using the other approaches (procedure C, 53%; procedure N, 41%). In conclusion, a shallow angle of approach using the SAX-OOP technique resulted in significantly fewer posterior vein wall injuries in central venous catheterization compared with steep angle techniques. PMID- 30276207 TI - Optimization of Ultrasound-Assisted Extraction Followed by Macroporous Resin Purification for Maximal Recovery of Functional Components and Removal of Toxic Components from Ginkgo biloba Leaves. AB - In the present study, the process of ultrasound-assisted extraction (UAE) followed by macroporous resin purification was successfully developed to achieve maximal recovery of functional components (flavonoids and ginkgolides) with minimal contents of toxic components (alkylphenols) from Ginkgo biloba leaves. Three effective extracted factors including HAc%, EtOH%, and UAE power were screened by Plackett-Burman design (PBD). The important variables were further optimized by rotatable central composite design (RCCD). By combination of PBD and RCCD, the resulting optimal UAE conditions were as follows: HAc% of 1.8%, EtOH% of 63%, ultrasound power of 303 W, G. biloba leaves powder amount of 1.0 g (solvent-to-solid ratio 40 mL/g), particle size of 60 mesh, extraction time of 40 min, and extraction temperature of 45 degrees C. Under the optimum conditions, the yield of flavonoids was 25.1 +/- 0.81 mg/g, ginkgolides was 10.6 +/- 0.57 mg/g, and alkylphenols was 3.96 +/- 0.31 mg/g. Moreover, the further enriching the functional components and removing toxic components from the obtained extracts of G. biloba leaves using the above optimum UAE condition was successfully achieved by macroporous resin DA-201. After column adsorption and desorption on DA-201, the content of total flavonoids was 36.51 +/- 1.53%, ginkgolides was 13.24 +/- 0.85%, and alkylphenols was 7.0 +/- 1.0 MUg/g from the obtained dry extracts (drug to extract ratio of 45-50:1) of G. biloba leaves which were complied with Chinese pharmacopoeias.

AB - Atrial fibrillation (AF) is a common arrhythmia for which the genetic studies mainly focused on the genes involved in electrical remodeling, rather than left atrial muscle remodeling. To identify rare variants involved in atrial myopathy using mutational screening, a high-throughput next-generation sequencing (NGS) workflow was developed based on a custom AmpliSeqTM panel of 55 genes potentially involved in atrial myopathy. This workflow was applied to a cohort of 94 patients with AF, 76 with atrial dilatation and 18 without. Bioinformatic analyses used NextGENe(r) software and in silico tools for variant interpretation. The AmpliSeq custom-made panel efficiently explored 96.58% of the targeted sequences. Based on in silico analysis, 11 potentially pathogenic missense variants were identified that were not previously associated with AF. These variants were located in genes involved in atrial tissue structural remodeling. Three patients were also carriers of potential variants in prevalent arrhythmia-causing genes, usually associated with AF. Most of the variants were found in patients with atrial dilatation (n=9, 82%). This NGS approach was a sensitive and specific method that identified 11 potentially pathogenic variants, which are likely to play roles in the predisposition to left atrial myopathy. Functional studies are needed to confirm their pathogenicity.

AB - Cystic echinococcosis is a serious zoonotic disease caused by Echinococcus granulosus species complex. The current study is the first attempt to determine the level of infection in domestic livestock and to explore the CE-related knowledge and awareness among livestock farmers in different districts of Khyber Pakhtunkhwa, province of Pakistan. A total of 1297 animals were examined for hydatid cysts including 538 cows, 428 buffaloes, 208 sheep, and 123 goats, at different slaughter houses in different districts of Khyber Pakhtunkhwa in 2 years from September 2015 to September 2017. For epidemiological investigations, prevalence in association with various factors (climate, age, and gender), organ specificity, types of cysts (fertile, sterile, or calcified), and viability of cysts parameters was recorded. Basing on the results obtained, areas with high prevalence were selected for further follow-ups and administration of questionnaires to the farmers and dog owners, to provide baseline data about this parasitic disease and to identify potential areas of emergence with correspondence animal and of public health significance. The finding of this study revealed the presence of CE in livestock of KP, Pakistan. The prevalence of hydatid cysts was the highest in buffaloes (15.88%) followed by cows (15.79%), sheep (15.38%), and goats (3.25%). Our investigation revealed close relationship between prevalence and animal age and gender in different months of the year. These findings also showed the highest prevalence of hydatid cysts in liver (63.49%), followed by lungs (23.80%) and mesentery (2.64%). Fertile and viable cysts were observed in all animal species except goats. The highest percentage of fertile and viable cysts was reported from the liver and lungs of sheep. For evaluation of risk factors, a total of 384 respondents were investigated. The results of current study revealed that 97.9% of farmers are not familiar with CE and transmission of this infection from dogs to human and livestock. The present study shows that CE will continue to be of medical and veterinary importance in Pakistan.

AB - Segmentation of the left ventricle (LV) from three-dimensional echocardiography (3DE) plays a key role in the clinical diagnosis of the LV function. In this work, we proposed a new automatic method for the segmentation of LV, based on the fully convolutional networks (FCN) and deformable model. This method implemented a coarse-to-fine framework. Firstly, a new deep fusion network based on feature fusion and transfer learning, combining the residual modules, was proposed to achieve coarse segmentation of LV on 3DE. Secondly, we proposed a method of geometrical model initialization for a deformable model based on the results of coarse segmentation. Thirdly, the deformable model was implemented to further optimize the segmentation results with a regularization item to avoid the leakage between left atria and left ventricle to achieve the goal of fine segmentation of LV. Numerical experiments have demonstrated that the proposed method outperforms the state-of-the-art methods on the challenging CETUS benchmark in the segmentation accuracy and has a potential for practical applications.

AB - Pseudomonas aeruginosa is a cause of high mortality in burn, immunocompromised, and surgery patients. High incidence of antibiotic resistance in this pathogen makes the existent therapy inefficient. Type three secretion system (T3SS) is a leading virulence system of P. aeruginosa that actively suppresses host resistance and enhances the severity of infection. Innovative therapeutic strategies aiming at inhibition of type three secretion system of P. aeruginosa are highly attractive, as they may reduce the severity of clinical manifestations and improve antibacterial immune responses. They may also represent an attractive therapy for antibiotic-resistant bacteria. Recently our laboratory developed a new small molecule inhibitor belonging to a class 2,4-disubstituted-4H-[1,3, 4] thiadiazine-5-ones, Fluorothiazinon (FT), that effectively suppressed T3SS in chlamydia and salmonella in vitro and in vivo. In this study, we evaluate the activity of FT towards antibiotic-resistant clinical isolates of P. aeruginosa expressing T3SS effectors ExoU and ExoS in an airway infection model. We found that FT reduced mortality and bacterial loads and decrease lung pathology and systemic inflammation. In addition, we show that FT inhibits the secretion of ExoT and ExoY, reduced bacteria cytotoxicity, and increased bacteria internalization in vitro. Overall, FT shows a strong potential as an antibacterial therapy of antibiotic-resistant P. aeruginosa infection. PMID- 30276213 TI - MultiParametric Magnetic Resonance Imaging-Based Nomogram for Predicting Prostate Cancer and Clinically Significant Prostate Cancer in Men Undergoing Repeat Prostate Biopsy. AB - Objective: To develop and internally validate nomograms based on multiparametric magnetic resonance imaging (mpMRI) to predict prostate cancer (PCa) and clinically significant prostate cancer (csPCa) in patients with a previous negative prostate biopsy. Materials and Methods: The clinicopathological parameters of 231 patients who underwent a repeat systematic prostate biopsy and mpMRI were reviewed. Based on Prostate Imaging and Reporting Data System, the mpMRI results were assigned into three groups: Groups "negative," "suspicious," and "positive." Two clinical nomograms for predicting the probabilities of PCa and csPCa were constructed. The performances of nomograms were assessed using area under the receiver operating characteristic curves (AUCs), calibrations, and decision curve analysis. Results: The median PSA was 15.03 ng/ml and abnormal DRE was presented in 14.3% of patients in the entire cohort. PCa was detected in 75 patients (32.5%), and 59 (25.5%) were diagnosed with csPCa. In multivariate analysis, age, prostate-specific antigen (PSA), prostate volume (PV), digital rectal examination (DRE), and mpMRI finding were significantly independent predictors for PCa and csPCa (all p < 0.01). Of those patients diagnosed with PCa or csPCa, 20/75 (26.7%) and 18/59 (30.5%) had abnormal DRE finding, respectively. Two mpMRI-based nomograms with super predictive accuracy were constructed (AUCs = 0.878 and 0.927, p < 0.001), and both exhibited excellent calibration. Decision curve analysis also demonstrated a high net benefit across a wide range of probability thresholds. Conclusion: mpMRI combined with age, PSA, PV, and DRE can help predict the probability of PCa and csPCa in patients who underwent a repeat systematic prostate biopsy after a previous negative biopsy. The two nomograms may aid the decision-making process in men with prior benign histology before the performance of repeat prostate biopsy.

AB - Chronic inflammatory diseases like diabetes are on a rise in the Western world. Based on the tsunami of new cases every year, new therapeutic measures must be considered. A promising avenue might involve the attenuation of underlying inflammation through natural health products (NHPs). This is because most NHPs have a rich history in traditional medicine and might be considered safer under appropriate doses and conditions. However, the biggest impediment in NHP research is that rarely do these products come with verified health benefits or dosing schedules established through modern scientific research. Fulvic acid (FvA), one such NHP, comes from humic substances produced by microorganisms in soil. Traditional medicine and modern research claim FvA can modulate the immune system, influence the oxidative state of cells, and improve gastrointestinal function; all of which are hallmarks of diabetes. This minireview outlines the available peer-reviewed research on FvA and examines its anecdotal health claims. We show that although available research has been minimal, there is substantial evidence to pursue FvA research in preventing chronic inflammatory diseases, including diabetes. PMID- 30276217 TI - Simvastatin-Induced Insulin Resistance May Be Linked to Decreased Lipid Uptake and Lipid Synthesis in Human Skeletal Muscle: the LIFESTAT Study. AB - Background: A prevalent side-effect of simvastatin is attenuated glucose homeostasis. The underlying mechanism is unknown, but impaired lipid metabolism may provide the link. The aim of this study was to investigate whether simvastatin-treated patients had a lower capacity to oxidize lipids and reduced expression of the major proteins regulating lipid uptake, synthesis, lipolysis, and storage in skeletal muscle than matched controls. Materials and Methods: Ten men were treated with simvastatin (HbA1c: 5.7 +/- 0.1%), and 10 healthy men (HbA1c: 5.2 +/- 0.1%) underwent an oral glucose tolerance test and a muscle biopsy was obtained. Fat oxidation rates were measured at rest and during exercise. Western blotting was used to assess protein content. Results: Patients treated with simvastatin had impaired glucose tolerance compared with control subjects, but fat oxidation at rest and during exercise was compatible. Skeletal muscle protein content of CD36, lipoprotein lipase (LPL), and diacylglycerol acyltransferase (DGAT) 1 were lower, and DGAT 2 tended to be lower in patients treated with simvastatin. Conclusions: Patients treated with simvastatin had a reduced capacity to synthesize FA and diacylglycerol (DAG) into triacylglycerol in skeletal muscle compared to matched controls. Decreased lipid synthesis capacity may lead to accumulation of lipotoxic intermediates (FA and DAG) and hence impair glucose tolerance. PMID- 30276218 TI - OSU-T315 as an Interesting Lead Molecule for Novel B Cell-Specific Therapeutics. AB - B cells are pathogenic in various disease processes and therefore represent an interesting target for the development of novel immunosuppressants. In the search for new therapeutic molecules, we utilized an in vitro B cell activation assay with ODN2006-stimulated Namalwa cells to screen a chemical library of small molecules for B cell modulating effects. OSU-T315, described as an inhibitor of integrin-linked kinase (ILK), was hereby identified as a hit. On human and murine primary B cells, OSU-T315 potently suppressed the proliferation and the production of antibodies and cytokines upon stimulation, suggesting that ILK could be a promising target in the modulation of B cell activity. Mice with B cell-specific knockout of ILK were generated. Surprisingly, knockout of ILK in murine B cells did not affect B cell function as assessed by several in vivo and ex vivo B cell assays and did not alter the B cell immunosuppressive activity of OSU-T315. In conclusion, OSU-T315 displays potency as B cell modulator, probably through a mechanism of action independent of ILK, and might serve as lead drug molecule for the development of novel B cell-selective drugs. PMID- 30276219 TI - Serum and Ectopic Endometrium from Women with Endometriosis Modulate Macrophage M1/M2 Polarization via the Smad2/Smad3 Pathway. AB - Objective: This study investigated the alterations in macrophage polarization in patients with endometriosis as well as the underlying molecular mechanisms. Methods: Peritoneal washings, serum samples, and endometrial tissues were collected from endometriosis patients and control subjects. Endometrial stromal cells (ESCs) were isolated from endometrial tissue, and conditioned medium was prepared by treating ESCs with or without various concentrations of interleukin- (IL-) 6, estrogen, or progestin. The frequencies of CD86+ and CD163+ cells and expression levels of these markers as well as the cytokines IL-12 and IL-10 were measured in THP-1- (human monocytic leukemia cell) derived macrophages. Results: There was a decrease in the percentage of CD86+ macrophages in the peritoneal wash solution of patients with endometriosis. Ectopic endometrial homogenates could promote M1 to M2 macrophage polarization in response to lipopolysaccharide (LPS), as evidenced by the increased percentage of CD163+ macrophages and increased IL-10 expression as well as a decreased percentage of CD86+ cells and lower IL-12 expression. In contrast, addition of serum from women with endometriosis to THP-1 cells resulted in the polarization of macrophages towards both M1 and M2 phenotypes. Upregulation of Smad2/Smad3 in macrophages upon exposure to eutopic and ectopic endometrial homogenates as well as serum of women with endometriosis was observed, and blockage of Smad2/Smad3 with their inhibitor SB431542 could reverse the macrophage polarization from M1 to M2. Conditioned medium induced by IL-6, but neither estrogen nor progestin, could facilitate M2 polarization. Neutralization of IL-6 diminished macrophage M2 polarization in endometriosis. Conclusion: This study provides detailed evidence supporting alterations in M1 to M2 macrophage polarization that may contribute to the initiation as well as progression of endometriosis. PMID- 30276220 TI - Quadriceps Strength Deficits After a Femoral Nerve Block Versus Adductor Canal Block for Anterior Cruciate Ligament Reconstruction: A Prospective, Single Blinded, Randomized Trial. AB - Background: Peripheral nerve blocks, particularly femoral nerve blocks (FNBs), are commonly performed for anterior cruciate ligament (ACL) reconstruction. However, associated quadriceps muscle weakness after FNBs is well described and may occur for up to 6 months postoperatively. The adductor canal block (ACB) has emerged as a viable alternative to the FNB, theoretically causing less quadriceps weakness during the immediate postoperative period, as it bypasses the majority of the motor fibers of the femoral nerve that branch off proximal to the adductor canal. Purpose/Hypothesis: This study sought to identify if a difference in quadriceps strength exists after an ACB or FNB for ACL reconstruction beyond the immediate postoperative period. Beyond the immediate postoperative period, we anticipated no difference in quadriceps strength between patients who received ACBs or FNBs for ACL reconstruction. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A total of 102 patients undergoing primary ACL reconstruction using a variety of graft types were enrolled between November 2015 and April 2016. All patients were randomized to receive an ACB or FNB before surgery, and the surgeon was blinded to the block type. All patients underwent aggressive rehabilitation without functional bracing postoperatively. The time to the first straight-leg raise was reported by the patient. Isokinetic strength testing was performed at 3 and 6 months postoperatively. Results: Data for 73 patients were analyzed. There was no significant difference in patient demographics of age, body mass index, sex, or tourniquet time between the FNB (n = 35) and ACB (n = 38) groups. The mean time to the first straight-leg raise was similar, at 13.1 +/- 1.0 hours for the FNB group and 15.5 +/- 1.2 hours for the ACB group (P = .134). The mean extension torque at 60 deg/s increased significantly for both the ACB (53.7% +/- 3.4% to 68.3% +/- 2.9%; P = .008) and the FNB (53.3% +/- 3.3% to 68.5% +/- 4.1%; P = .006) groups from 3 to 6 months postoperatively. There was also no significant difference in mean extension torque at 60 deg/s or 180 deg/s between the FNB and ACB groups at 3 and 6 months. There were no significant differences in postoperative complications (infection, arthrofibrosis, retear) between groups. Conclusion: Although prior studies have shown immediate postoperative benefits of ACBs compared with FNBs, with a faster return of quadriceps strength, in the current study there was no statistically or clinically significant difference in quadriceps strength at 3 and 6 months postoperatively in patients who received ACBs or FNBs for ACL reconstruction.

PMID- 30276222 TI - Evaluation of deep learning methods for parotid gland segmentation from CT images. AB - The segmentation of organs at risk is a crucial and time-consuming step in radiotherapy planning. Good automatic methods can significantly reduce the time clinicians have to spend on this task. Due to its variability in shape and low contrast to surrounding structures, segmenting the parotid gland is challenging. Motivated by the recent success of deep learning, we study the use of two dimensional (2-D), 2-D ensemble, and three-dimensional (3-D) U-Nets for segmentation. The mean Dice similarity to ground truth is ~0.83 for all three models. A patch-based approach for class balancing seems promising for false positive reduction. The 2-D ensemble and 3-D U-Net are applied to the test data of the 2015 MICCAI challenge on head and neck autosegmentation. Both deep learning methods generalize well onto independent data (Dice 0.865 and 0.88) and are superior to a selection of model- and atlas-based methods with respect to the Dice coefficient. Since appropriate reference annotations are essential for training but often difficult and expensive to obtain, it is important to know how many samples are needed for training. We evaluate the performance after training with different-sized training sets and observe no significant increase in the Dice coefficient for more than 250 training cases.

PMID- 30276224 TI - The Role of Learning in Threat Imminence and Defensive Behaviors. AB - Life threatening situations as urgent as defending against a predator precludes the use of slow trial and error strategies. Natural selection has led to the evolution of a behavioral system that has 3 critical elements. 1) When it is activated it limits the behaviors available to the organism to a set of prewired responses that have proven over phylogeny to be effective at defense. 2) A rapid learning system, called Pavlovian fear conditioning, that has the ability to immediately identify threats and promote prewired defensive behaviors. 3) That learning system has the ability to integrate several informational dimensions to determine threat imminence and this allows the organism to match the most effective defensive behavior to the current situation. The adaptive significance of conscious experiential states is also considered.

AB - This data article presents an expert system and econometric entropy-based informatics model for residential building project for cost judgment and decisions in residential building project. The data was obtained using purposive sampling technique to select projects completed between 2009 and 2011in Lagos state Nigeria, the project were examined for their cost centres. Also, As-built cost of one thousand(1000) samples of trained As-built cost of residential building projects trained with Neural network with Levenberg Marqua after being adjusted and modified with econometric factors like inflation index, cost entropy and entropy factor to stabilized the data and were used to form and train neural network used. Probability technique was used to generate risk impact matrix and influence of entropy on the cost centres. A parametric model similar to hedonic models was generated using the utility parameters within the early and late elemental dichotomy. The model was validated through comparative analysis of the econometric loading attributes using Monte Carlo technique of SPSS software extracting the contingency coefficient. The data of the model can provide solution to the problems of knowing the cost implication of a future project and also enable a builder or contactor load cost implication of an unseen circumstance even on occasion of deferred cost reimbursement.

PMID- 30276231 TI - Carotid artery plaque uptake of 11C-PK11195 inversely correlates with circulating monocytes and classical CD14++CD16- monocytes expressing HLA-DR. AB - Background: We explored the relation between blood concentrations of monocyte/lymphocyte subsets and carotid artery plaque macrophage content, measured by positron emission tomography (PET) with 11C-PK11195. Methods and results: In 9 patients with carotid plaques we performed 11C-PK11195-PET/computed tomography angiography imaging and measurement of absolute concentrations and frequencies of circulating monocytes and T-cell subsets. Plaque standardized uptake value (SUV) for 11C-PK11195 was negatively correlated with concentrations of total monocytes (r = -0.58, p = 0.05) and CD14++CD16-HLA-DR+ classical subset (r = -0.82, p = 0.005). These correlations hold true also in relation to plaque target to background ratio. No correlation was observed between plaque SUV and CD3+T lymphocytes, CD4+T lymphocytes nor with activated CD3+CD4+T cells expressing HLA-DR. Conclusions: We first demonstrated a reduction in the absolute concentration of monocytes and particularly in classical monocytes expressing HLA DR in the presence of an increased uptake of 11C-PK11195 in carotid plaques. The present work, despite being a pilot study comprising only a small number of subjects provides new insights in the search for specific cellular biomarkers with potential diagnostic and prognostic value in patients with a known carotid plaque.

AB - Atherosclerosis (AS) manifested by lipid accumulation, extracellular matrix protein deposition, and calcification in the intima and media of the large to medium size arteries promoting arterial stiffness and reduction of elasticity. It has been accepted that AS leads to increased morbidity and mortality worldwide. Recent studies indicated that genetic abnormalities play an important role in the development of AS. Specific genetic mutation and histone modification have been found to induce AS formation. Furthermore, specific RNAs such as microRNAs and circular RNAs have been identified to play a crucial role in the progression of AS. Nevertheless, the mechanisms by which genetic mutation, DNA and histone modification, microRNAs and circular RNA induce AS still remain elusive. This review describes specific mechanisms and pathways through which genetic mutation, DNA and histone modification, microRNAs and circular RNA instigate AS. This review further provides a therapeutic strategic direction for the treatment of AS targeting genetic mechanisms. PMID- 30276234 TI - Androgen receptor expression in normal breast tissue and subsequent breast cancer risk. AB - Sex steroid hormone signaling is critical in the development of breast cancers, although the role of the androgen receptor remains unclear. This study evaluated androgen receptor (AR) expression in normal breast tissue as a potential marker of breast cancer risk. We conducted a nested case-control study of women with benign breast disease (BBD) within the Nurses' Health Studies. Epithelial AR expression was assessed by immunohistochemistry in normal tissue from the BBD biopsy and the percent of positive nuclei was estimated in ordinal categories of 10% for 78 breast cancer cases and 276 controls. Logistic regression models adjusting for the matching factors and BBD lesion type were used to calculate odds ratios (ORs) for the association between AR expression (tertiles: <=10%, 11 30%, and >30%) and breast cancer risk. AR expression in normal breast tissue was not associated with subsequent breast cancer risk (ORT3vsT1 = 0.9, 95% CI = 0.4 1.8, p trend = 0.68). In comparison with low AR/low ER women, ORs of 0.4 (95% CI = 0.1-1.2) for high AR/high ER women, 1.8 (95% CI = 0.4-7.8) for low AR/high ER women, and 0.7 (95% CI = 0.3-1.6) for high AR/low ER women were observed (p interaction = 0.21). Ki67 did not modify the association between AR expression and breast cancer risk (p interaction = 0.75). There was little evidence for an overall association between AR expression in normal breast tissue and breast cancer risk. These findings did not show that the AR association varied by Ki67 expression in normal breast tissue, though there was suggestive heterogeneity by ER expression.

There is a continuing need to design new effective catalysts especially with the drive toward using sustainable resources. The identification that gold is an exceptionally effective catalyst has paved the way for a new class of active heterogeneous and homogeneous catalysts for a broad range of reactions. As a heterogeneous catalyst gold is the most active catalyst for the oxidation of carbon monoxide at ambient temperature. It is also the most effective catalyst for the synthesis of vinyl chloride by acetylene hydrochlorination, and a gold catalyst has recently been commercialized in China for this reaction. In this outlook the nature of the active gold species for these two reactions will be explored. PMID- 30276243 TI - Bioinspired Designs of Superhydrophobic and Superhydrophilic Materials. AB - Bioinspired designs of superhydrophobic and superhydrophilic materials have been an important and fascinating area of research in recent years for their extensive potential application prospects from industry to our daily life. Despite extensive progress, existing research achievements are far from real applications. From biomimetic performance to service life, the related research has faced serious problems at present. A timely outlook is therefore necessary to summarize the existing research, to discuss the challenges faced, and to propose constructive advice for the ongoing scientific trend. Here, we comb the process of development of bioinspired superhydrophobic and superhydrophilic materials at first. Then, we also describe how to design artificial superhydrophobic and superhydrophilic materials. Furthermore, current challenges faced by bioinspired designs of superhydrophobic and superhydrophilic materials are pointed out, separately, and the possible solutions are discussed. Emerging applications in this field are also briefly considered. Finally, the development trend within this field is highlighted to lead future research. PMID- 30276245 TI - Hunting for Organic Molecules with Artificial Intelligence: Molecules Optimized for Desired Excitation Energies. AB - This work presents a proof-of-concept study in artificial-intelligence-assisted (AI-assisted) chemistry where a machine-learning-based molecule generator is coupled with density functional theory (DFT) calculations, synthesis, and measurement. Although deep-learning-based molecule generators have shown promise, it is unclear to what extent they can be useful in real-world materials development. To assess the reliability of AI-assisted chemistry, we prepared a platform using a molecule generator and a DFT simulator, and attempted to generate novel photofunctional molecules whose lowest excited states lie at desired energetic levels. A 10 day run on the 12-core server discovered 86 potential photofunctional molecules around target lowest excitation levels, designated as 200, 300, 400, 500, and 600 nm. Among the molecules discovered, six were synthesized, and five were confirmed to reproduce DFT predictions in ultraviolet visible absorption measurements. This result shows the potential of AI-assisted chemistry to discover ready-to-synthesize novel molecules with modest computational resources.

AB - We report Phoenics, a probabilistic global optimization algorithm identifying the set of conditions of an experimental or computational procedure which satisfies desired targets. Phoenics combines ideas from Bayesian optimization with concepts from Bayesian kernel density estimation. As such, Phoenics allows to tackle typical optimization problems in chemistry for which objective evaluations are limited, due to either budgeted resources or time-consuming evaluations of the conditions, including experimentation or enduring computations. Phoenics proposes new conditions based on all previous observations, avoiding, thus, redundant evaluations to locate the optimal conditions. It enables an efficient parallel search based on intuitive sampling strategies implicitly biasing toward exploration or exploitation of the search space. Our benchmarks indicate that Phoenics is less sensitive to the response surface than already established optimization algorithms. We showcase the applicability of Phoenics on the Oregonator, a complex case-study describing a nonlinear chemical reaction network. Despite the large search space, Phoenics quickly identifies the conditions which yield the desired target dynamic behavior. Overall, we recommend Phoenics for rapid optimization of unknown expensive-to-evaluate objective functions, such as experimentation or long-lasting computations.

AB - Understanding the surface of semiconductor nanocrystals (NCs) prepared using colloidal methods is a long-standing goal of paramount importance for all their potential optoelectronic applications, which remains unsolved largely because of the lack of site-specific physical techniques. Here, we show that multidimensional 113Cd dynamic nuclear polarization (DNP) enhanced NMR spectroscopy allows the resolution of signals originating from different atomic and magnetic surroundings in the NC cores and at the surfaces. This enables the determination of the structural perfection, and differentiation between the surface and core atoms in all major forms of size- and shape-engineered CdSe NCs: irregularly faceted quantum dots (QDs) and atomically flat nanoplatelets, including both dominant polymorphs (zinc-blende and wurtzite) and their epitaxial nanoheterostructures (CdSe/CdS core/shell quantum dots and CdSe/CdS core/crown nanoplatelets), as well as magic-sized CdSe clusters. Assignments of the NMR signals to specific crystal facets of oleate-terminated ZB structured CdSe NCs are proposed. Significantly, we discover far greater atomistic complexity of the surface structure and the species distribution in wurtzite as compared to zinc blende CdSe QDs, despite an apparently identical optical quality of both QD polymorphs. PMID- 30276247 TI - Free Energy Landscape of the Complete Transport Cycle in a Key Bacterial Transporter. AB - PepTSo is a proton-coupled bacterial symporter, from the major facilitator superfamily (MFS), which transports di-/tripeptide molecules. The recently obtained crystal structure of PepTSo provides an unprecedented opportunity to gain an understanding of functional insights of the substrate transport mechanism. Binding of the proton and peptide molecule induces conformational changes into occluded (OC) and outward-facing (OF) states, which we are able to characterize using molecular dynamics (MD) simulations. The structural knowledge of the OC and OF state is important to fully understand the major energy barrier associated with the transport cycle. In order to gain functional insight into the interstate dynamics, we performed extensive all atom MD simulations. The Markov state model was constructed to identify the free energy barriers between the states, and kinetic information on intermediate pathways was obtained using the transition pathway theory (TPT). TPT shows that the OF state is obtained by the movement of TM1 and TM7 at the extracellular side approximately 12-16 A away from each other, and the inward movement of TM4 and TM10 at the intracellular halves to 3-4 A characterizes the OC state. Helix distance distributions obtained from MD simulations were compared with experimental double electron-electron resonance spectroscopy and were found to be in excellent agreement with previous studies. We also predicted the optimal positions for placement of methane thiosulfonate spin label probes to capture the slowest protein dynamics. Our finding sheds light on the conformational cycle of this key membrane transporter and the functional relationships between the multiple intermediate states. PMID- 30276248 TI - Rationalizing Steroid Interactions with Lipid Membranes: Conformations, Partitioning, and Kinetics. AB - Steroids have numerous physiological functions associated with cellular signaling or modulation of the lipid membrane structure and dynamics, and as such, they have found broad pharmacological applications. Steroid-membrane interactions are relevant to multiple steps of steroid biosynthesis and action, as steroids are known to interact with neurotransmitter or membrane steroid receptors, and steroids must cross lipid membranes to exert their physiological functions. Therefore, rationalizing steroid function requires understanding of steroid membrane interactions. We combined molecular dynamics simulations and isothermal titration calorimetry to characterize the conformations and the energetics of partitioning, in addition to the kinetics of flip-flop transitions and membrane exit, of 26 representative steroid compounds in a model lipid membrane. The steroid classes covered in this study include birth control and anabolic drugs, sex and corticosteroid hormones, neuroactive steroids, as well as steroids modulating the lipid membrane structure. We found that the conformational ensembles adopted by different steroids vary greatly, as quantified by their distributions of tilt angles and insertion depths into the membrane, ranging from well-defined steroid conformations with orientations either parallel or normal to the membrane, to wide conformational distributions. Surprisingly, despite their chemical diversity, the membrane/water partition coefficient is similar among most steroids, except for structural steroids such as cholesterol, leading to similar rates for exiting the membrane. By contrast, the rates of steroid flip flop vary by at least 9 orders of magnitude, revealing that flip-flop is the rate limiting step during cellular uptake of polar steroids. This study lays the ground for a quantitative understanding of steroid-membrane interactions, and it will hence be of use for studies of steroid biosynthesis and function as well as for the development and usage of steroids in a pharmacological context. PMID- 30276249 TI - End-On Bound Iridium Dinuclear Heterogeneous Catalysts on WO3 for Solar Water Oxidation. AB - Heterogeneous catalysts with atomically defined active centers hold great promise for high-performance applications. Among them, catalysts featuring active moieties with more than one metal atom are important for chemical reactions that require synergistic effects but are rarer than single atom catalysts (SACs). The difficulty in synthesizing such catalysts has been a key challenge. Recent progress in preparing dinuclear heterogeneous catalysts (DHCs) from homogeneous molecular precursors has provided an effective route to address this challenge. Nevertheless, only side-on bound DHCs, where both metal atoms are affixed to the supporting substrate, have been reported. The competing end-on binding mode, where only one metal atom is attached to the substrate and the other metal atom is dangling, has been missing. Here, we report the first observation that end-on binding is indeed possible for Ir DHCs supported on WO3. Unambiguous evidence supporting the binding mode was obtained by in situ diffuse reflectance infrared Fourier transform spectroscopy and high-angle annular dark-field scanning transmission electron microscopy. Density functional theory calculations provide additional support for the binding mode, as well as insights into how end-on bound DHCs may be beneficial for solar water oxidation reactions. The results have important implications for future studies of highly effective heterogeneous catalysts for complex chemical reactions. PMID- 30276250 TI - Expanding the Chemical Space of Biocompatible Fluorophores: Nanohoops in Cells. AB - The design and optimization of fluorescent molecules has driven the ability to interrogate complex biological events in real time. Notably, most advances in bioimaging fluorophores are based on optimization of core structures that have been known for over a century. Recently, new synthetic methods have resulted in an explosion of nonplanar conjugated macrocyclic molecules with unique optical properties yet to be harnessed in a biological context. Herein we report the synthesis of the first aqueous-soluble carbon nanohoop (i.e., a macrocyclic slice of a carbon nanotube prepared via organic synthesis) and demonstrate its bioimaging capabilities in live cells. Moreover, we illustrate that these scaffolds can be easily modified by well-established "click" chemistry to enable targeted live cell imaging. This work establishes the nanohoops as an exciting new class of macrocyclic fluorophores poised for further development as novel bioimaging tools. PMID- 30276251 TI - Surface Fluctuations Dominate the Slow Glassy Dynamics of Polymer-Grafted Colloid Assemblies. AB - Colloids grafted with a corona layer of polymers show glassy behavior that covers a wide range of fragilities, with this behavior being tunable through variations in grafting density and grafting chain length. We find that the corona roughness, which is maximized for long chain lengths and sparse grafting, is directly correlated to the concentration-dependence of the system relaxation time (fragility). Relatively rougher colloids result in stronger liquids because their rotational motions become orientationally correlated across the whole system even at low particle loadings leading to an essentially Arrhenius-like concentration dependence of the relaxation times near the glass transition. The smoother colloids do not show as much orientational correlation except at higher densities leading to fragile behavior. We therefore propose that these materials are an ideal model to study the physical properties of the glass transition. PMID- 30276252 TI - Molecular Simulation of Chemical Reaction Equilibrium by Computationally Efficient Free Energy Minimization. AB - The molecular simulation of chemical reaction equilibrium (CRE) is a challenging and important problem of broad applicability in chemistry and chemical engineering. The primary molecular-based approach for solving this problem has been the reaction ensemble Monte Carlo (REMC) algorithm [Turner et al. Molec. Simulation2008, 34, (2), 119-146], based on classical force-field methodology. In spite of the vast improvements in computer hardware and software since its original development almost 25 years ago, its more widespread application is impeded by its computational inefficiency. A fundamental problem is that its MC basis inhibits the implementation of significant parallelization, and its successful implementation often requires system-specific tailoring and the incorporation of special MC approaches such as replica exchange, expanded ensemble, umbrella sampling, configurational bias, and continuous fractional component methodologies. We describe herein a novel CRE algorithm (reaction ensemble molecular dynamics, ReMD) that exploits modern computer hardware and software capabilities, and which can be straightforwardly implemented for systems of arbitrary size and complexity by exploiting the parallel computing methodology incorporated within many MD software packages (herein, we use GROMACS for illustrative purposes). The ReMD algorithm utilizes these features in the context of a macroscopically inspired and generally applicable free energy minimization approach based on the iterative approximation of the system Gibbs free energy function by a mathematically simple convex ideal solution model using the composition at each iteration as a reference state. Finally, we additionally describe a simple and computationally efficient a posteriori method to estimate the equilibrium concentrations of species present in very small amounts relative to others in the primary calculation. To demonstrate the algorithm, we show its application to two classic example systems considered previously in the literature: the N2-O2-NO system and the ammonia synthesis system. PMID- 30276253 TI - Visualizing Structural Transformation and Guest Binding in a Flexible Metal Organic Framework under High Pressure and Room Temperature. AB - Understanding the effect of gas molecules on the framework structures upon gas sorption in porous materials is highly desirable for the development of gas storage and separation technologies. However, this remains challenging for flexible metal-organic frameworks (MOFs) which feature "gate-opening/gate closing" or "breathing" sorption behaviors under external stimuli. Herein, we report such a flexible Cd-MOF that exhibits "gating effect" upon CO2 sorption. The ability of the desolvated flexible Cd-MOF to retain crystal singularity under high pressure enables the direct visualization of the reversible closed-/open pore states before and after the structural transformation as induced by CO2 adsorption/desorption through in situ single-crystal X-ray diffraction experiments. The binding sites of CO2 molecules within the flexible MOF under high pressure and room temperature have also been identified via combined in situ single-crystal X-ray diffraction and powder X-ray diffraction studies, facilitating the elucidation of the states observed during gate-opening/gate closing behaviors. Our work therefore lays a foundation to understand the high pressure gas sorption within flexible MOFs at ambient temperature, which will help to improve the design efforts of new flexible MOFs for applications in responsive gas sorption and separation. PMID- 30276254 TI - A Lamin-Binding Ligand Inhibits Homologous Recombination Repair of DNA Double Strand Breaks. AB - Nuclear lamins are type V intermediate filament proteins. Lamins, including LA, LB1, LB2, and LC, are the major protein components forming the nuclear lamina to support the mechanical stability of the mammalian cell nucleus. Increasing evidence has shown that LA participates in homologous recombination (HR) repair of DNA double-strand breaks (DSBs) . However, the mechanisms underlying this process are incompletely understood. We recently identified the first lamin binding ligand 1 (LBL1) that directly binds LA and inhibited cancer cell growth. We provided here further mechanistic investigations of LBL1 and revealed that LA interacts with the HR recombinase Rad51 to protect Rad51 from degradation. LBL1 inhibits LA-Rad51 interaction leading to accelerated proteasome-mediated degradation of Rad51, culminating in inhibition of HR repair of DSBs. These results uncover a novel post-translational regulation of Rad51 by LA and suggest that targeting the LA-Rad51 axis may represent a promising strategy to develop cancer therapeutics. PMID- 30276255 TI - Chemogenetic Approach Using Ni(II) Complex-Agonist Conjugates Allows Selective Activation of Class A G-Protein-Coupled Receptors. AB - Investigating individual G-protein-coupled receptors (GPCRs) involved in various signaling cascades can unlock a myriad of invaluable physiological findings. One of the promising strategies for addressing the activity of each subtype of receptor is to design chemical turn-on switches on the target receptors. However, valid methods to selectively control class A GPCRs, the largest receptor family encoded in the human genome, remain limited. Here, we describe a novel approach to chemogenetically manipulate activity of engineered class A GPCRs carrying a His4 tag, using metal complex-agonist conjugates (MACs). This manipulation is termed coordination tethering. With the assistance of coordination bonds, MACs showed 10-100-fold lower EC50 values in the engineered receptors, compared with wild-type receptors. Such coordination tethering enabled selective activation of beta2-adrenoceptors and muscarinic acetylcholine receptors, without loss of natural receptor responses, in living mammalian cells, including primary cultured astrocytes. Our generalized, modular chemogenetic approach should facilitate more precise control and deeper understanding of individual GPCR signaling pathways in living systems. PMID- 30276256 TI - A Size Threshold for Enhanced Magnetoresistance in Colloidally Prepared CoFe2O4 Nanoparticle Solids. AB - The phenomenon of granular magnetoresistance offers the promise of rapid functional materials discovery and high-sensitivity, low-cost sensing technology. Since its discovery over 25 years ago, a major challenge has been the preparation of solids composed of well-characterized, uniform, nanoscale magnetic domains. Rapid advances in colloidal nanochemistry now facilitate the study of more complex and finely controlled materials, enabling the rigorous exploration of the fundamental nature and maximal capabilities of this intriguing class of spintronic materials. We present the first study of size-dependence in granular magnetoresistance using colloidal nanoparticles. These data demonstrate a strongly nonlinear size-dependent magnetoresistance with smaller particles having strong DeltaR/R ~ 18% at 300 K and larger particles showing a 3-fold decline. Importantly, this indicates that CoFe2O4 can act as an effective room temperature granular magnetoresistor and that neither a high superparamagnetic blocking temperature nor a low overall resistance are determining factors in viable magnetoresistance values for sensing applications. These results demonstrate the promise of wider exploration of nontraditional granular structures composed of nanomaterials, molecule-based magnets, and metal-organic frameworks. PMID- 30276257 TI - On Demand Switching of Polymerization Mechanism and Monomer Selectivity with Orthogonal Stimuli. AB - The development of next-generation materials is coupled with the ability to predictably and precisely synthesize polymers with well-defined structures and architectures. In this regard, the discovery of synthetic strategies that allow on demand control over monomer connectivity during polymerization would provide access to complex structures in a modular fashion and remains a grand challenge in polymer chemistry. In this Article, we report a method where monomer selectivity is controlled during the polymerization by the application of two orthogonal stimuli. Specifically, we developed a cationic polymerization where polymer chain growth is controlled by a chemical stimulus and paired it with a compatible photocontrolled radical polymerization. By alternating the application of the chemical and photochemical stimuli the incorporation of vinyl ethers and acrylates could be dictated by switching between cationic and radical polymerization mechanisms, respectively. This enables the synthesis of multiblock copolymers where each block length is governed by the amount of time a stimulus is applied, and the quantity of blocks is determined by the number of times the two stimuli are toggled. This new method allows on demand control over polymer structure with external influences and highlights the potential for using stimuli controlled polymerizations to access novel materials. PMID- 30276258 TI - A Universal Descriptor for the Entropy of Adsorbed Molecules in Confined Spaces. AB - Confinement of hydrocarbons in nanoscale pockets and pores provides tunable capability for controlling molecules in catalysts, sorbents, and membranes for reaction and separation applications. While computation of the enthalpic interactions of hydrocarbons in confined spaces has improved, understanding and predicting the entropy of confined molecules remains a challenge. Here we show, using a set of nine aluminosilicate zeolite frameworks with broad variation in pore and cavity structure, that the entropy of adsorption can be predicted as a linear combination of rotational and translational entropy. The extent of entropy lost upon adsorption is predicted using only a single material descriptor, the occupiable volume (V occ). Predictive capability of confined molecular entropy permits an understanding of the relation with adsorption enthalpy, the ability to computationally screen microporous materials, and an understanding of the role of confinement on the kinetics of molecules in confined spaces. PMID- 30276259 TI - Iridium-Tungsten Alloy Nanodendrites as pH-Universal Water-Splitting Electrocatalysts. AB - The development of highly efficient and durable electrocatalysts for high performance overall water-splitting devices is crucial for clean energy conversion. However, the existing electrocatalysts still suffer from low catalytic efficiency, and need a large overpotential to drive the overall water splitting reactions. Herein, we report an iridium-tungsten alloy with nanodendritic structure (IrW ND) as a new class of high-performance and pH universal bifunctional electrocatalysts for hydrogen and oxygen evolution catalysis. The IrW ND catalyst presents a hydrogen generation rate ~2 times higher than that of the commercial Pt/C catalyst in both acid and alkaline media, which is among the most active hydrogen evolution reaction (HER) catalysts yet reported. The density functional theory (DFT) calculations reveal that the high HER intrinsic catalytic activity results from the suitable hydrogen and hydroxyl binding energies, which can accelerate the rate-determining step of the HER in acid and alkaline media. Moreover, the IrW NDs show superb oxygen evolution reaction (OER) activity and much improved stability over Ir. The theoretical calculation demonstrates that alloying Ir metal with W can stabilize the formed active iridium oxide during the OER process and lower the binding energy of reaction intermediates, thus improving the Ir corrosion resistance and OER kinetics. Furthermore, the overall water-splitting devices driven by IrW NDs can work in a wide pH range and achieve a current density of 10 mA cm-2 in acid electrolyte at a low potential of 1.48 V. PMID- 30276260 TI - Quantitative Analysis of Calcium Phosphate Nanocluster Growth Using Time-of Flight Medium-Energy-Ion-Scattering Spectroscopy. AB - One of the remaining challenges in material chemistry is to unveil the quantitative compositional/structural information and thermodynamic nature of inorganic materials especially in the initial nucleation and growth step. In this report, we adopted newly developed time-of-flight medium-energy-ion-scattering (TOF-MEIS) spectroscopy to address this challenge and explored heterogeneously grown nanometer-sized calcium phosphate as a model system. With TOF-MEIS, we discovered the existence of calcium-rich nanoclusters (Ca/P ~ 3) in the presence of the non-collagenous-protein-mimicking passivating ligands. Over the reaction, these clusters progressively changed their compositional ratio toward that of a bulk phase (Ca/P ~ 1.67) with a concurrent increase in their size to ~2 nm. First principles studies suggested that the calcium-rich nanoclusters can be stabilized through specific interactions between the ligands and clusters, emphasizing the important role of template on guiding the chemical and thermodynamic nature of inorganic materials at the nanoscale. PMID- 30276261 TI - Sodium-Ion Hybrid Capacitor of High Power and Energy Density. AB - Sodium-ion hybrid capacitors (NHCs) have been attracting research interest in recent years. However, NHCs suffer from slower redox reaction kinetics of electrodes as compared to non-Faradaic capacitive counterparts. Herein, a high performance NHC using porous NaBi as anode, activated carbon (AC) as cathode, and 1.5 M of NaPF6 in diglyme as electrolyte is reported. In a charging process, Na+ is inserted into NaBi to form Na3Bi, and PF6 - is stored in the electric double layers of the AC cathode; in a reverse process, the Na3Bi is desodiated to NaBi and eventually Bi, and the adsorbed PF6 - is released into the electrolyte in the first cycle. The NHC exhibits a capacity of ~298 mA h gBi -1, capacity retention of 98.6% after 1000 cycles at 2 A gBi -1, and Coulombic efficiency of >99.4%. The achievable power and energy density are as high as 11.1 kW kgtotal -1 and 106.5 W h kgtotal -1, respectively. The superior electrochemical performance is ascribed to the gradually formed three-dimensional (3D) porous and stable networks of the anode, ensuring its comparable fast reaction kinetics and cycle stability to the AC cathode. PMID- 30276262 TI - Structural and Biochemical Insights into the Function and Evolution of Sulfoquinovosidases. AB - An estimated 10 billion tonnes of sulfoquinovose (SQ) are produced and degraded each year. Prokaryotic sulfoglycolytic pathways catabolize sulfoquinovose (SQ) liberated from plant sulfolipid, or its delipidated form alpha-d-sulfoquinovosyl glycerol (SQGro), through the action of a sulfoquinovosidase (SQase), but little is known about the capacity of SQ glycosides to support growth. Structural studies of the first reported SQase (Escherichia coli YihQ) have identified three conserved residues that are essential for substrate recognition, but crossover mutations exploring active-site residues of predicted SQases from other organisms have yielded inactive mutants casting doubt on bioinformatic functional assignment. Here, we show that SQGro can support the growth of E. coli on par with d-glucose, and that the E. coli SQase prefers the naturally occurring diastereomer of SQGro. A predicted, but divergent, SQase from Agrobacterium tumefaciens proved to have highly specific activity toward SQ glycosides, and structural, mutagenic, and bioinformatic analyses revealed the molecular coevolution of catalytically important amino acid pairs directly involved in substrate recognition, as well as structurally important pairs distal to the active site. Understanding the defining features of SQases empowers bioinformatic approaches for mapping sulfur metabolism in diverse microbial communities and sheds light on this poorly understood arm of the biosulfur cycle. PMID- 30276264 TI - Evidence of a low-temperature dynamical transition in concentrated microgels. AB - A low-temperature dynamical transition has been reported in several proteins. We provide the first observation of a "protein-like" dynamical transition in nonbiological aqueous environments. To this aim, we exploit the popular colloidal system of poly-N-isopropylacrylamide (PNIPAM) microgels, extending their investigation to unprecedentedly high concentrations. Owing to the heterogeneous architecture of the microgels, water crystallization is avoided in concentrated samples, allowing us to monitor atomic dynamics at low temperatures. By elastic incoherent neutron scattering and molecular dynamics simulations, we find that a dynamical transition occurs at a temperature T d ~ 250 K, independently from PNIPAM mass fraction. However, the transition is smeared out on approaching dry conditions. The quantitative agreement between experiments and simulations provides evidence that the transition occurs simultaneously for PNIPAM and water dynamics. The similarity of these results with hydrated protein powders suggests that the dynamical transition is a generic feature in complex macromolecular systems, independently from their biological function. PMID- 30276263 TI - Structural and Mechanistic Insights into the Catalytic-Domain-Mediated Short Range Glycosylation Preferences of GalNAc-T4. AB - Mucin-type O-glycosylation is initiated by a family of polypeptide GalNAc transferases (GalNAc-Ts) which are type-II transmembrane proteins that contain Golgi luminal catalytic and lectin domains that are connected by a flexible linker. Several GalNAc-Ts, including GalNAc-T4, show both long-range and short range prior glycosylation specificity, governed by their lectin and catalytic domains, respectively. While the mechanism of the lectin-domain-dependent glycosylation is well-known, the molecular basis for the catalytic-domain dependent glycosylation of glycopeptides is unclear. Herein, we report the crystal structure of GalNAc-T4 bound to the diglycopeptide GAT*GAGAGAGT*TPGPG (containing two alpha-GalNAc glycosylated Thr (T*), the PXP motif and a "naked" Thr acceptor site) that describes its catalytic domain glycopeptide GalNAc binding site. Kinetic studies of wild-type and GalNAc binding site mutant enzymes show the lectin domain GalNAc binding activity dominates over the catalytic domain GalNAc binding activity and that these activities can be independently eliminated. Surprisingly, a flexible loop protruding from the lectin domain was found essential for the optimal activity of the catalytic domain. This work provides the first structural basis for the short-range glycosylation preferences of a GalNAc-T. PMID- 30276265 TI - Unprecedented high irreversibility line in the nontoxic cuprate superconductor (Cu,C)Ba2Ca3Cu4O11+delta. AB - One of the key factors that limit the high-power applications for a type II superconductor is the irreversibility line H irr(T), which reflects the very boundary of resistive dissipation in the phase diagram of magnetic field versus temperature. In cuprate family, the Y-, Bi-, Hg-, and Tl-based systems have superconducting transition temperatures exceeding the liquid nitrogen boiling temperature (~77 K). However, the toxic elements Hg and Tl in the latter two systems strongly constrain the applications. The best perspective so far is relying on the YBa2Cu3O7-delta (T c ~ 90 K) system, which is nontoxic and has a relatively high irreversibility magnetic field. We report the study of a nontoxic superconductor (Cu,C)Ba2Ca3Cu4O11+delta with T c = 116 K. We found that the irreversibility magnetic field is extremely high, and it thus provides great potential for applications above the liquid nitrogen temperature. PMID- 30276266 TI - Enhanced transport in transistor by tuning transition-metal oxide electronic states interfaced with diamond. AB - High electron affinity transition-metal oxides (TMOs) have gained a central role in two-dimensional (2D) electronics by enabling unprecedented surface charge doping efficiency in numerous exotic 2D solid-state semiconductors. Among them, diamond-based 2D electronics are entering a new era by using TMOs as surface acceptors instead of previous molecular-like unstable acceptors. Similarly, surface-doped diamond with TMOs has recently yielded record sheet hole concentrations (2 * 1014 cm-2) and launched the quest for its implementation in microelectronic devices. Regrettably, field-effect transistor operation based on this surface doping has been so far disappointing due to fundamental material obstacles such as (i) carrier scattering induced by nonhomogeneous morphology of TMO surface acceptor layer, (ii) stoichiometry changes caused by typical transistor fabrication process, and (iii) carrier transport loss due to electronic band energy misalignment. This work proposes and demonstrates a general strategy that synergistically surmounts these three barriers by developing an atomic layer deposition of a hydrogenated MoO3 layer as a novel efficient surface charge acceptor for transistors. It shows high surface uniformity, enhanced immunity to harsh fabrication conditions, and benefits from tunable electronic gap states for improving carrier transfer at interfaces. These breakthroughs permit crucial integration of TMO surface doping into transistor fabrication flows and allow outperforming electronic devices to be reached. PMID- 30276268 TI - Multidimensional spectroscopy with attosecond extreme ultraviolet and shaped near infrared pulses. AB - Dynamics following excitation with attosecond extreme ultraviolet (XUV) pulses arise from enormous numbers of accessible excited states, complicating the retrieval of state-specific time evolutions. We develop attosecond XUV multidimensional spectroscopy here to separate interfering pathways on a near infrared (NIR) energy axis, retrieving single state dynamics in argon atoms in a two-dimensional (2D) XUV-NIR spectrum. In this experiment, we measure four-wave mixing signal arising from the interaction of XUV attosecond pulses centered around 15 eV with two few-cycle NIR pulses. The 2D spectrum is created by measuring the emitted XUV signal field spectrum while applying narrowband amplitude and phase modulations to one of the NIR pulses. Application of such a technique to systems of high dimensionality will provide for the observation of state-resolved pure electronic dynamics, in direct analogy to phenomena unraveled by multidimensional spectroscopies at optical frequencies. PMID- 30276267 TI - An "ideal lignin" facilitates full biomass utilization. AB - Lignin, a major component of lignocellulosic biomass, is crucial to plant growth and development but is a major impediment to efficient biomass utilization in various processes. Valorizing lignin is increasingly realized as being essential. However, rapid condensation of lignin during acidic extraction leads to the formation of recalcitrant condensed units that, along with similar units and structural heterogeneity in native lignin, drastically limits product yield and selectivity. Catechyl lignin (C-lignin), which is essentially a benzodioxane homopolymer without condensed units, might represent an ideal lignin for valorization, as it circumvents these issues. We discovered that C-lignin is highly acid-resistant. Hydrogenolysis of C-lignin resulted in the cleavage of all benzodioxane structures to produce catechyl-type monomers in near-quantitative yield with a selectivity of 90% to a single monomer. PMID- 30276269 TI - Preoperative Needle Insertion Path Planning for Minimizing Deflection in Multilayered Tissues. AB - Fine needle deflection is a problem encountered during insertion into a soft tissue. Although an axial rotational insertion is an effective approach for minimizing this problem, needle deflection still depends on the insertion angle with respect to the tissue boundary. Since the human body consists of multi layered tissues of various shapes and mechanical properties, preoperative planning of an optimal path is a key factor for achieving a successful insertion. In this paper, we propose an optimization-based preoperative path planning model that minimizes needle deflection during multi-layered tissue insertion. This model can determine the optimal path based on the sum of insertion angles with respect to each tissue boundary that the needle passes through. To increase the accuracy of the model, we incorporated the effect of distances from tissue boundaries and the probability that the deflection is acceptable by incorporating weighting factors into the model. To validate the model, we performed experiments involving four scenarios of two- and three-layered tissues. The results showed that the proposed model is capable of determining the optimal insertion path in all scenarios. PMID- 30276270 TI - Le Fort Partial Colpocleisis: A Low-Cost Model. AB - Objective: The aim of this study is to develop a simulation model for the Le Fort partial colpocleisis. Introduction: One in 9 women will undergo surgery for incontinence or prolapse by age 80 with 30% of these requiring an additional prolapse surgery. With a success rate of over 90% and recurrence rate of 4.2%, obliterative procedures hold a significant place in the management of pelvic organ prolapse in elderly women who are no longer sexually active. For new trainees, the Le Fort colpocleisis may be difficult to conceptually visualize, requiring the need to develop models as teaching tools. Method: A low-cost model was developed using easily available craft supplies to simulate the Le Fort partial colpocleisis with the uterus in situ to treat procidentia. The cost of each model was under US $14 and time to make was approximately 1 hour. The video presents the construction and use of this model. Conclusions: The Le Fort partial colpocleisis technique has been in use for over a century. The aging population as well as the high risk of recurrence after prolapse repairs makes colpocleisis an important technique for trainees to master. Simulation models have proven their efficacy as a training tool. This simple model will allow trainees to fully comprehend the steps of this procedure. Using this video, educators can construct a model and use it to orient trainees to the Le Fort partial colpocleisis procedure. PMID- 30276271 TI - Amnion-derived stem cell transplantation: A novel treatment for neurological disorders. AB - In this review, we evaluated the literature reporting the use of amniotic stem cells (ASCs) in regenerative medicine for the treatment of neurological disorders. There is an increasing amount of evidence that indicates the exacerbation of the primary injury by inflammation in neurological disorders characterized by rampant inflammation, thereby increasing damage to the central nervous system (CNS). To address this, we focus on the amnion cells' anti inflammatory properties, which make their transplantation a promising treatment for these disorders. In addition, we offered insights into new applications of the ASC in the fields of regenerative medicine and tissue engineering. PMID- 30276273 TI - Effects of erythropoietin combined with tissue plasminogen activator on the rats following cerebral ischemia and reperfusion. AB - OBJECTIVES: Exogenously administered recombinant human erythropoietin (rhEPO) has been reported to exhibit neuroprotective effects in animal models. However, there are still have some controversies that combination of EPO and tissue plasminogen activator (tPA) in acute ischemic stroke. In the present study, we investigated the effects of local intra-arterial infusion of low-dose EPO in combination with tPA on focal cerebral ischemic stroke. MATERIALS AND METHODS: Sixty adult male Sprague-Dawley rats were randomly divided into five groups, including sham, vehicle, EPO, tPA, and EPO+tPA groups. Rats were subjected to middle cerebral artery occlusion (MCAO) and administrated with EPO (800 U/kg, middle cerebral artery injection), tPA (10 mg/kg, tail vein injection), EPO+tPA, or saline (vehicle) onset of reperfusion. Neurobehavioral deficits, infarct volume, brain edema, the expression of tight junction proteins (Claudin-5, Occludin), and AQP4 were assessed following 2 h ischemia and 24 h reperfusion. The number of apoptotic cells in the periinfarct region was detected by the terminal deoxyribonucleotide transferase dUTP nick end labeling (TUNEL) staining. RESULTS: The neurobehavioral deficits, brain infarct volume, edema volume, TUNEL-positive cells and downregulation of Claudin-5 and Occludin were alleviated by EPO or EPO plus tPA, following the ischemia/reperfusion (I/R) in rats. The EPO and EPO plus tPA both reduced the upregulation of AQP4 in the ischemic brain tissue. CONCLUSION: Our data demonstrate local intra-arterial infusion of low-dose EPO in combination with tPA protected against focal cerebral ischemia in rats manifested by a decrease in brain edema and blood-brain barrier (BBB) disruption after 2 h ischemia and 24 h reperfusion. PMID- 30276274 TI - Pyruvate dehydrogenase complex in cerebral ischemia-reperfusion injury. AB - Pyruvate dehydrogenase (PDH) complex is a mitochondrial matrix enzyme that serves a critical role in the conversion of anaerobic to aerobic cerebral energy. The regulatory complexity of PDH, coupled with its significant influence in brain metabolism, underscores its susceptibility to, and significance in, ischemia reperfusion injury. Here, we evaluate proposed mechanisms of PDH-mediated neurodysfunction in stroke, including oxidative stress, altered regulatory enzymatic control, and loss of PDH activity. We also describe the neuroprotective influence of antioxidants, dichloroacetate, acetyl-L-carnitine, and combined therapy with ethanol and normobaric oxygen, explained in relation to PDH modulation. Our review highlights the significance of PDH impairment in stroke injury through an understanding of the mechanisms by which it is modulated, as well as an exploration of neuroprotective strategies available to limit its impairment. PMID- 30276275 TI - Rationale for ischemic conditioning to prevent stroke in patients with intracranial arterial stenosis. AB - Intracranial atherosclerotic arterial stenosis (ICAS) is one of the most common causes of stroke worldwide and is associated with particularly a high risk of recurrent stroke. Although aggressive medical management, consisting of dual antiplatelet therapy and intensive control of vascular risk factors, has improved the prognosis of patients with ICAS, subgroups of patients remain at very high risk of stroke. More effective therapies for these high-risk patients are urgently needed. One promising treatment is remote limb ischemic conditioning, which involves producing repetitive, transient ischemia of a limb by inflating a blood pressure cuff with the intention of protecting the brain from subsequent ischemia. In this study, we review the limitations of currently available treatments, discuss the potential mechanisms of action of ischemic conditioning, describe the preclinical and clinical data suggesting a possible role of ischemic conditioning in treating patients with ICAS, and outline the questions that still need to be answered in future studies of ischemic conditioning in subjects with ICAS. PMID- 30276272 TI - Biomarkers for acute diagnosis and management of stroke in neurointensive care units. AB - The effectiveness of current management of critically ill stroke patients depends on rapid assessment of the type of stroke, ischemic or hemorrhagic, and on a patient's general clinical status. Thrombolytic therapy with recombinant tissue plasminogen activator (r-tPA) is the only effective treatment for ischemic stroke approved by the Food and Drug Administration (FDA), whereas no treatment has been shown to be effective for hemorrhagic stroke. Furthermore, a narrow therapeutic window and fear of precipitating intracranial hemorrhage by administering r-tPA cause many clinicians to avoid using this treatment. Thus, rapid and objective assessments of stroke type at admission would increase the number of patients with ischemic stroke receiving r-tPA treatment and thereby, improve outcome for many additional stroke patients. Considerable literature suggests that brain specific protein biomarkers of glial [i.e. S100 calcium-binding protein B (S100B), glial fibrillary acidic protein (GFAP)] and neuronal cells [e.g., ubiquitin C-terminal hydrolase-L1 (UCH-L1), neuron-specific enolase (NSE), alphaII-spectrin breakdown products SBDP120, SBDP145, and SBDP150, myelin basic protein (MBP), neurofilament light chain (NF-L), tau protein, visinin-like protein-1 (VLP 1), NR2 peptide] injury that could be detected in the cerebrospinal fluid (CSF) and peripheral blood might provide valuable and timely diagnostic information for stroke necessary to make prompt management and decisions, especially when the time of stroke onset cannot be determined. This information could include injury severity, prognosis of short-term and long-term outcomes, and discrimination of ischemic or hemorrhagic stroke. This chapter reviews the current status of the development of biomarker-based diagnosis of stroke and its potential application to improve stroke care. PMID- 30276276 TI - Wake-up stroke: Dawn of a new era. AB - Wake-up stroke or stroke with unclear onset of symptoms is known to occur in one fourth of ischemic stroke patients. These patients are not considered for thrombolytic therapy based on time designation of their symptom onset as per the current guidelines. Observational studies have investigated the pathophysiology and suggested actual onset of symptoms to be approximate to the awakening time for these patients. Use of advanced imaging modalities in these patients tends to identify favorable patient profiles for thrombolysis. Results of the ongoing trials will likely beckon a seminal juncture in stroke therapy and deliver critical modifications in the current treatment guidelines for thrombolysis in this substantial, yet neglected, group of stroke patients. In this article, we have reviewed the predisposing factors, preferred imaging modalities and various ongoing thrombolytic and endovascular trials to date for patients with unclear time of symptom onset or who wake up with stroke symptoms. PMID- 30276277 TI - Detrimental effects of physical inactivity on neurogenesis. AB - Patients diagnosed with neurological disorders exhibit a variety of physical and psychiatric symptoms, including muscle atrophy, general immobility, and depression. Patients who participate in physical rehabilitation at times show unexpected clinical improvement, which includes diminished depression and other stress-related behaviors. Regenerative medicine has advanced two major stem cell based therapies for central nervous system (CNS) disorders, transplantation of exogenous stem cells, and enhancing the endogenous neurogenesis. The latter therapy utilizes a natural method of re-innervating the injured brain, which may mend neurological impairments. In this study, we examine how inactivity-induced atrophy, using the hindlimb suspension model, alters neurogenesis in rats. The hypothesis is that inactivity inhibits neurogenesis by decreasing circulation growth or trophic factors, such as vascular endothelial growth or neurotrophic factors. The restriction modifies neurogenesis and stem cell differentiation in the CNS, the stem cell microenvironment is examined by the trophic and growth factors, including stress-related proteins. Despite growing evidence revealing the benefits of "increased" exercise on neurogenesis, the opposing theory involving "physical inactivity," which simulates pathological states, continues to be neglected. This novel theory will allow us to explore the effects on neurogenesis by an intransigent stem cell microenvironment likely generated by inactivity. 5-bromo-2-deoxyuridine labeling of proliferative cells, biochemical assays of serum, cerebrospinal fluid, and brain levels of trophic factors, growth factors, and stress-related proteins are suggested identifiers of neurogenesis, while evaluation of spontaneous movements will give insight into the psychomotor effects of inactivity. Investigations devised to show how in vivo stimulation, or lack thereof, affects the stem cell microenvironment are necessary to establish treatment methods to boost neurogenesis in bedridden patients. PMID- 30276279 TI - Clinical characteristics of 37 Chinese patients with myotonic dystrophy Type 1. AB - OBJECTIVE: This study aims to investigate clinical characteristics of 37 Chinese patients with Myotonic dystrophy Type 1 (DM1). METHODS: Main clinical features of these cases were analyzed, with a focus on multi-system involvements. RESULTS: The median age of onset was 21.5 years, with a range from 3 to 45 years. Fourteen patients had a family history positive for DM1, whereas the other 23 were sporadic cases. Twenty-seven of the patients were male. The primary symptoms were myotonia and weakness with varying multi-system involvement including cardiac defects, cataracts, sleep disturbances, cholecystopathy, and peripheral neuropathy. CONCLUSIONS: This is the first report in China with the diagnosis of DM1 decisively confirmed by CTG expansion testing. Data from our study suggest that Chinese DM1 cases have different clinical characteristics compared with those of Caucasian cases, especially the prevalence of cardiac defects, cataracts, and sleep disturbances.

AB - [This corrects the article on p. 53 in vol. 1.]. PMID- 30276278 TI - Regeneration after stroke: Stem cell transplantation and trophic factors. AB - Stroke is a leading cause of death and disability worldwide. However, there is only one Food and Drug Administration-approved drug for the treatment of ischemic stroke, i.e., tissue plasminogen activator, and its therapeutic window is limited to within 4.5 h after stroke. Since clinical trials for neuroprotection have failed to demonstrate efficacy, multipotent and pluripotent stem cell transplantations are viable candidates for stroke treatment by providing trophic factor support and/or cell replacement following injury. The goal of this review is to highlight the promise of stem cell transplantation as vehicles for trophic factor delivery. The beneficial effects of different stem cell types as transplants as well as ways to upregulate trophic factors in stem cells are described in this review. Stem cell transplantation has consistently shown beneficial effects in the ischemic stroke model, in part due to the beneficial factors that stem cells release around the stroke injury area, resulting in smaller infarct volumes and regeneration and functional recovery. Upregulation of beneficial factors in stem cells and neural progenitors before transplantation has been shown to be even more effective in treating the stroke injury than stem cells without upregulated factors. However, for both stem cells and genetic engineering, there remain many unanswered questions and potential for improvement. These include modifiable parameters such as the different stem cell types and different factors, as well as the various readouts for investigation, such as various in vivo effects, such as immune system modulation and enhancement of endogenous neurogenesis and angiogenesis. PMID- 30276280 TI - A rare case report of bilateral internal carotid artery hypoplasia in postpartum female: Clinical spectrum and role of various modalities in diagnosis. AB - Congenital hypoplasia of bilateral internal carotid arteries (ICAs) is an extremely rare anomaly with less than 25 reported cases in literature till date. We present a case of a 30-year-old primigravida, who developed seizures and subsequently loss of consciousness just few minutes after the delivery of a healthy male child. To the best of our knowledge, this is the first case with bilateral ICA hypoplasia presenting in postpartum female who developed infarct in bilateral frontal region and subarachnoid hemorrhage (SAH). On a postpartum three dimensional (3D) computed tomography (CT) angiography, bilateral ICA hypoplasia was confirmed and the manifestations of infarcts were probably the consequence of altered hemodynamics of pregnancy. In conclusion, a patient in her late pregnancy and postpartum period, having nonspecific cerebral symptoms or having suffered a cerebrovascular accident, should not only be evaluated for pregnancy or puerperium-related complications but also whenever possible a baseline screening with Doppler study of neck vessels and a noncontrast magnetic resonance imaging (MRI) angiography of neck and cerebral vessels should be performed to rule out congenital anomalies. PMID- 30276282 TI - Current challenges in regenerative medicine for central nervous system disorders. PMID- 30276284 TI - Intra-arterial delivery of mesenchymal stem cells. AB - While treatments have been developed to combat stroke, such as intravenous recombinant tissue plasminogen activator and endovascular recanalization therapies, their ability to decrease the long-term disability that accompanies stroke is limited. Currently, stem cell research focused on mesenchymal stem cells (MSCs). MSCs are multipotent, nonhematopoietic stem cells found in the stromal fraction of the bone marrow, along with the connective tissue of most organs. MSCs are an increasingly appealing cell source due to the relative ease in which they can be retrieved, developed, and handled in vitro. Despite the fact that numerous paths of stem cell transport to the brain in acute ischemic stroke (AIS) exist, the intra-arterial (IA) route of stem cell transport is most attractive. This is due to its great potential for clinical translation, especially considering the growing clinical application of endovascular treatment for AIS. Here, we evaluate research examining IA delivery of MSCs to the stroke region. The results of the study revealed the maximum tolerated dose and that the optimal time for administration was 24 h, following cerebral ischemia. It is important that future translational studies are performed to establish IA administration of MSCs as a widely used treatment for AIS. PMID- 30276283 TI - Tracking mesenchymal stem cells using magnetic resonance imaging. AB - Recent translational studies in the fields of tissue regeneration and cell therapy have characterized mesenchymal stem cells (MSCs) as a potentially effective and accessible measure for treating ischemic cerebral and neurodegenerative disorders such as stroke, Parkinson's disease, and amyotrophic lateral sclerosis. Developing more efficient cell tracking techniques bear the potential to optimize MSC transplantation therapies by providing a more accurate picture of the fate and area of effect of implanted cells. Currently, determining the location of transplanted MSCs involves a histological approach, but magnetic resonance imaging (MRI) presents a noninvasive paradigm that permits repeat evaluations. To visualize MSCs using MRI, the implanted cells must be treated with an intracellular contrast agent. These are commonly paramagnetic compounds, many of which are based on superparamagnetic iron oxide (SPIO) nanoparticles. Recent research has set out characterize the effects of SPIO-uptake on the cellular activity of in vitro human MSCs and the resultant influence that respective SPIO concentration has on MRI sensitivity. As these studies reveal, SPIO-uptake has no effect on the cellular processes of proliferation and differentiation while producing high contrast MRI signals. Moreover, transplantation of SPIO-labeled MSCs in animal models encouragingly showed no loss in MRI contrast, suggesting that SPIO labeling may be an appealing regime for lasting MRI detection.

PMID- 30276285 TI - Reducing excitoxicity with glutamate transporter-1 to treat stroke. AB - The neurotransmitter glutamate is released following ischemic brain damage, and its excitotoxic effects contribute greatly to the development of stroke. Because this release of glutamate occurs within minutes, therapeutic drugs targeting the restriction of glutamate-induced excitotoxicity must be administered quickly following ischemic onset. Here, we evaluate an alternative research approach examining the overexpression of glutamate transporter 1 (GLT1) to reduce infarction and improve behavioral deficits induced by stroke in a rat model of stroke. Recent studies verify the role of glutamate overflow in the pathogenesis of stroke. The experimental approach evaluated glutamate clearance, following ischemia-induced overflow where the GLT had been genetically manipulated to be overexpressed in the ischemic region. A viral vector-mediated gene transfer approach activated the overexpression of GLT1 to successfully reduce ischemia induced glutamate overflow, decrease cell death, and improve behavioral recovery among animal models. These findings further support the role of glutamate in the pathogenesis of stroke and the upregulation of endogenous GLT1 as a promising approach to protect against the effects of ischemic brain damage caused by glutamate excitotoxicity.

PMID- 30276286 TI - Clinical application of oligodendrocyte precursor cells for cell-based therapy. AB - Oligodendrocyte precursor cells (OPCs), which give rise to mature oligodendrocytes (OLs), play important roles in maintaining white matter function. Even during the adulthood period, OPCs comprise roughly 5% of all cells in the forebrain and retain a capability to become myelinated OLs. Recently, OPCs have been proposed as a novel source for cell-based therapy. For the purpose, OPCs can be obtained from embryonic stem cells, induced pluripotent stem cells, and directly converted cells derived from patients. Here, we will provide a brief review of the potential of using OPCs as a cell-based therapy for treating various neurological diseases. PMID- 30276287 TI - A polarizing view on posttraumatic brain injury inflammatory response. AB - Traumatic brain injury (TBI) activates the simultaneous proliferation of various pro- and anti-inflammatory molecules. Considering the amount of factors participating, this response is naturally complex. However, there is an increasing trend in neurotrauma research to delineate the injury-induced inflammatory responses within the constraints of in vitro defined macrophage polarization phenotypes "M1" and "M2". Here, we evaluate research examining the complexity of the inflammatory response that cannot be so easily characterized using this binary nomenclature. TBI is demonstrated to induce a broad spectrum of simultaneous expression responses involving both pro- and anti-inflammatory reactions. Specifically, the research revealed a very heterogeneous parenchymal landscape associated with TBI. The concurrent expression of both "M1" and "M2" phenotypic markers on the microglia/macrophages involved suggests that the polarization phenotypes cannot be neatly defined in this M1/M2 paradigm. Recent studies displaying neurotrauma also report similar conflict with the constraints of this binary categorization of "M1/M2", demonstrating that microglia/macrophages cannot effectively cross-over to strictly polarized "M1 only" or "M2-only" phenotype. Therefore, the complex signaling events surrounding this response indicate that a binary M1/M2 characterization is not adequate to define inflammatory profile. This paper is a review article.

PMID- 30276288 TI - Finding effective biomarkers for pediatric traumatic brain injury. AB - As traumatic brain injury (TBI) continues to affect children and young adults worldwide, research on reliable biomarkers grows as a possible aid in determining the severity of injury. However, many studies have revealed that diverse biomarkers such as S100B and myelin basic protein (MBP) have many limitations, such as their elevated normative concentrations in young children. Therefore, the results of these studies have yet to be translated to clinical applications. However, despite the setbacks of research into S100B and MBP, investigators continue to research viable biomarkers, notably glial fibrillary acidic protein (GFAP) and ubiquitin C-terminal hydrolase L1 (UCH-L1), as possible aids in medical decision making. Studies have revealed that GFAP and UCH-L1 actually are better predictors of injury progression than the before-mentioned biomarkers S100B and MBP. In addition, UCH-L1 has demonstrated an ability to detect injury while CT is negative, suggesting an ability to detect acute intracranial lesions. Here, we evaluate research testing levels of GFAP and UCH-L1 on children diagnosed with TBI and compare our results to those of other tested biomarkers. In a recent study done by Hayes et al., GFAP and UCH-L1 demonstrated the potential to recognize children with the possibility of poor outcome, allowing for more specialized treatments with clinical and laboratory applications. Although studies on GFAP and UCH-L1 have for the most part warranted positive results, further studies will be needed to confirm their role as reliable markers for pediatric TBI. PMID- 30276289 TI - Creatine supplementation improves neural progenitor cell survival in Huntington's disease. AB - Preclinical and clinical studies suggest that striatal transplantation of neural stem cells (NSCs) and neural progenitor cells (NPCs) may be an appealing and valuable system for treating Huntington's disease. Nevertheless, for a neural replacement to become an effective translational treatment for Huntington's disease, a certain number of difficulties must be addressed, including how to improve the integration of transplanted cell grafts with the host tissue, to elevate the survival rates of transplanted cells, and to ensure their directed differentiation into specific neuronal phenotypes. Research focusing on the translational applications of creatine (Cr) supplementation in NSC and NPC cell replacement therapies continues to offer promising results, pointing to Cr as a factor with the potential to improve cell graft survivability and encourage differentiation toward GABAergic phenotypes in models of striatal transplantation. Here, we evaluate research examining the outcomes of Cr supplementation and how the timing of supplementation regimes may affect their efficacy. The recent studies indicate that Cr's effects vary according to the developmental stage of the cells being treated, noting the dynamic differences in creatine kinase expression over the developmental stages of differentiating NPCs. This research continues to move Cr supplementation closer to the widespread clinical application and suggests such techniques warrant further examination. PMID- 30276290 TI - A therapeutic shock propels Schwann cells to proliferate in peripheral nerve injury. AB - Damage to the peripheral nervous system (PNS) is a prevalent issue and represents a great burden to patients. Although the PNS has a good capacity for regeneration, regeneration over long distances poses several difficulties. Several recent studies have addressed Schwann cells' limited proliferative capacity; however, a solution has yet to be found. Here, we examine the effects of extracorporeal shock wave therapy (ESWT) on Schwann cell isolation, culture, and proliferation rate. The study conducted demonstrated that Schwann cells treated with ESWT had significantly improved isolation, culture, and proliferative capacities. These findings represent a solution to a significant problem that hospitals and health-care providers face every year: how to treat long distance damage to the PNS with the limited proliferative capabilities of Schwann cells. Although these findings are promising, further studies must be conducted to address the molecular mechanisms by which ESWT alters Schwann cells and the potential implications for peripheral nerve damage and other prevalent illnesses.

PMID- 30276291 TI - Nonhuman primate model in clinical modeling of diseases for stem cell therapy. AB - Nonhuman primates (NHPs) are alike humans in size, behavior, physiology, biochemistry, and immunology. Given close similarities to humans, the NHP model offers exceptional opportunities to understand the biological mechanisms and translational applications with direct relevance to human conditions. Here, we evaluate the opportunities and limitations of NHPs as animal models for translational regenerative medicine. NHP models of human disease propose exceptional opportunities to advance stem cell-based therapy by addressing pertinent translational concerns related to this research. Nonetheless, the value of these primates must be carefully assessed, taking into account the expense of specialized equipment and requirement of highly specialized staff. Well-designed initial fundamental studies in small animal models are essential before translating research into NHP models and eventually into human trials. In addition, we suggest that applying a directed and collaborative approach, as seen in the evolution of stroke NHP models, will greatly benefit the translation of stem cell therapy in other NHP disease models. PMID- 30276292 TI - Science, ethics and communication remain essential for the success of cell-based therapies. AB - Cell-based therapeutics, such as marrow or peripheral blood stem cell transplantation, are a standard of care for certain malignancies. More recently, a wider variety of cell-based therapeutics including the use of mesenchymal stromal/stem cells, T-cells, and others show great promise in a wider range of diseases. With increased efforts to expand cell-based treatments to several clinical settings, many institutions around the world have developed programs to explore cellular therapy's potential for safe and effective applications. In legitimate investigations, usually conducted through academic centers or biotechnology industry-sponsored efforts, these studies are regulated and peer reviewed to ensure safety and clear determination of potential efficacy. However, in some cases, the use of cell-based approaches is conducted with insufficient preclinical data, scientific rationale, and/or study plan for the diseases claimed to be treated, with patients being charged for these services without clear evidence of clinical benefit. In this context, patients may not be properly informed regarding the exact treatment they are receiving within a consenting process that may not be completely valid or ethical. Here, the authors emphasize the importance of distinguishing "proven cell-based therapies" from "unproven" and unauthorized cell-based therapies. This publication also addresses the necessity for improved communication between the different stakeholders in the field, patient associations, and advocacy groups in particular, to favor medical innovation and provide legitimate benefits to patients. Considering the progressive growth of cell-based treatments, their increasing therapeutic value and the expectation that society has about these therapies, it is critically important to protect patients and ensure that the risk/benefit ratio is favorable.

PMID- 30276295 TI - Endovascular therapy for acute ischemic stroke: The standard of care. AB - Acute ischemic stroke continues to be a major cause of permanent disability and death worldwide. Outcomes are particularly poor in patients presenting with large vessel occlusive disease with resultant ischemia and tissue injury in large and eloquent territories. Intravenous thrombolysis has been the mainstay of medical therapy, however treatment is limited to a subset of patients and many patients continue to have poor outcomes. Three trials in 2013 investigating the benefit of intra-arterial therapy failed to demonstrate benefit over medical therapy alone. More recently, five trials in 2015 were completed demonstrating superior outcomes with intra-arterial therapy with improved results attributed to higher and faster rates of recanalization in a select patient population. These trials have introduced a new standard of care in the management of acute ischemic stroke patients. PMID- 30276294 TI - Facial nerve stimulation as a future treatment for ischemic stroke. AB - Stimulation of the autonomic parasympathetic fibers of the facial nerve system (hereafter simply "facial nerve") rapidly dilates the cerebral arteries and increases cerebral blood flow whether that stimulation is delivered at the facial nerve trunk or at distal points such as the sphenopalatine ganglion. Facial nerve stimulation thus could be used as an emergency treatment of conditions of brain ischemia such as ischemic stroke. A rich history of scientific research has examined this property of the facial nerve, and various means of activating the facial nerve can be employed including noninvasive means. Herein, we review the anatomical and physiological research behind facial nerve stimulation and the facial nerve stimulation devices that are in development for the treatment of ischemic stroke. PMID- 30276296 TI - Region-specific disruption of synapsin phosphorylation following ethanol administration in brain-injured mice. AB - Introduction: Civilians and military personnel develop a range of physical and psychosocial impairments following traumatic brain injury (TBI), including alcohol abuse. As a consequence, increased rates of alcohol misuse magnify TBI induced pathologies and impede rehabilitation efforts. Therefore, a developed understanding of the mechanisms that foster susceptibility of the injured brain to alcohol sensitivity and the response of the injured brain to alcohol is imperative for the treatment of TBI patients. Alcohol sensitivity has been demonstrated to be increased following experimental TBI and, in additional studies, regulated by presynaptic vesicle release mechanisms, including synapsin phosphorylation. Materials and Methods: Mice were exposed to controlled midline impact of the intact skull and assessed for cortical, hippocampal, and striatal expression of phosphorylated synapsin I and II in response to high-dose ethanol exposure administered 14 days following injury, a time point at which injured mice demonstrate increased sedation after ethanol exposure. Results and Discussion: Immunoblot quantitation revealed that TBI alone, compared to sham controls, significantly increased phosphorylated synapsin I and II protein expression in the striatum. In sham controls, ethanol administration significantly increased phosphorylated synapsin I and II protein expression compared to saline-treated sham controls; however, no significant increase in ethanol-induced phosphorylated synapsin I and II protein expression was observed in the striatum of injured mice compared to saline-treated TBI controls. A similar expression pattern was observed in the cortex although restricted to increases in phosphorylated synapsin II. Conclusion: These data show that increased phosphorylated synapsin expression in the injured striatum may reflect a compensatory neuroplastic response to TBI which is proposed to occur as a result of a compromised presynaptic response of the injured brain to high-dose ethanol. These results offer a mechanistic basis for the altered ethanol sensitivity observed following experimental TBI and contribute to our understanding of alcohol action in the injured brain. PMID- 30276297 TI - beta4 integrin is not essential for localization of hemidesmosome proteins plectin and CD151 in cerebral vessels. AB - Objective: In the central nervous system (CNS), beta4 integrin is predominantly expressed by endothelial cells lining arterioles. As beta4 integrin plays an essential role in epithelial tissues, organizing structural proteins into specialized adhesive structures called hemidesmosomes (HD), the aim of this study was to determine whether it plays a similar role in CNS endothelium. Methods: Dual-immunofluorescence was used to examine the relationship between beta4 integrin expression and co-expression of the HD proteins plectin and CD151 in frozen sections of mouse brain, both under normoxic (control) conditions and following chronic mild hypoxia. The requirement of beta4 integrin for the localization of HD proteins was examined in transgenic mice lacking beta4 integrin expression specifically in endothelial cells (beta4-EC-KO mice). Results: Immunofluorescence revealed that in the normal adult CNS, plectin and CD151 strongly co-localized with beta4 integrin in arterioles. However, in the chronic mild hypoxia model, in which extensive cerebrovascular remodeling is observed, plectin and CD151 were strongly upregulated on all cerebral vessels, but surprisingly, in capillaries, this occurred in a beta4 integrin-independent manner. Unexpectedly, absence of endothelial beta4 integrin (in beta4-EC-KO mice) had no impact on the expression level or distribution pattern of plectin and CD151 within stable or remodeling cerebral vessels. Conclusions: These results demonstrate that the HD proteins plectin and CD151 are closely associated with beta4 integrin on arterioles in normal brain, and are strongly upregulated on remodeling blood vessels. However, unlike its described role in the epidermis, beta4 integrin is not essential for localization or regulation of expression of plectin and CD151 in cerebral vessels. PMID- 30276293 TI - Targeting oxidative stress for the treatment of ischemic stroke: Upstream and downstream therapeutic strategies. AB - Excessive oxygen and its chemical derivatives, namely reactive oxygen species (ROS), produce oxidative stress that has been known to lead to cell injury in ischemic stroke. ROS can damage macromolecules such as proteins and lipids and leads to cell autophagy, apoptosis, and necrosis to the cells. This review describes studies on the generation of ROS, its role in the pathogenesis of ischemic stroke, and recent development in therapeutic strategies in reducing oxidative stress after ischemic stroke. PMID- 30276299 TI - Activated complement protein C5a does not affect brain-derived endothelial cell viability and zonula occludens-1 levels following oxygen-glucose deprivation. AB - BACKGROUND AND PURPOSE: Ischemic brain injury induces both functional and structural disarray affecting the blood-brain barrier (BBB) which in return aggravates stroke outcomes. Complement system and its bioactive proteins are important molecular responders to ischemia. C5a protein along with its receptor C5a receptor 1 is a key component of this system with potent pro-inflammatory and chemoattractant properties. The purpose of this study is to investigate the role of C5a protein and its receptor which are believed to participate in the inflammatory response that follows ischemic insult. MATERIALS AND METHODS: To mimic an ischemic in vivo event in which C5a may contact brain endothelial cells after injury, we studied oxygen-glucose deprivation (OGD) followed by reperfusion in brain microvascular endothelial cells (b.End. 3) by only added C5a at the time of reperfusion. Cell death and viability were estimated by trypan blue and 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assays, respectively. Tight junction protein zonula occluden (ZO-1) levels were analyzed by Western blot analysis, and nitric oxide (NO) was assessed using the Griess reagent. RESULTS: Brain-derived endothelial cell was susceptible to OGD-induced injury in a duration-dependent manner as was the presence of ZO-1 protein. However, the addition of C5a protein had no notable effects even when used at high concentrations up to 100 nM. While OGD led to reduction in ZO-1 protein levels, no change was seen following the addition of C5a. Finally, OGD led unexpectedly to small decreases in NO generation, but this was again unaltered by C5a. CONCLUSIONS: Our study suggests that complement system protein C5a may not have a direct role in the disruption of BBB, following brain ischemia. This is in contrary with previous literature that suggests a possible role of this protein in the inflammatory response to ischemia. PMID- 30276300 TI - MicroRNA-99a-5p in circulating immune cells as a potential biomarker for the early diagnosis of ischemic stroke. AB - OBJECTIVES: We have previously shown the neuroprotective function of microRNA-99a 5p in experimental stroke. Here, we explore its diagnostic potential for acute stroke patients. MATERIALS AND METHODS: MiR-99a-5p levels in circulating from acute stroke patients and control were measured by real-time polymerase chain reaction. Pearson's correlation and receiver operator characteristic (ROC) curves were used to analyze clinical significance of miR-99a-5p and its sensitivity and specificity for stroke diagnosis. RESULTS: We demonstrated that miR-99a-5p expression was upregulated in neutrophils of both ischemic stroke and hemorrhage patients, while was only increased in the lymphocytes of hemorrhage patients. ROC analysis revealed that the miR-99a-5p level in neutrophils and lymphocytes had a moderate diagnostic value for stroke. Moreover, a positive correlation existed between plasma miR-99a-5p levels and neutrophil numbers or neutrophil/lymphocyte ratio. Meanwhile, miR-99a-5p levels in neutrophils were negatively correlated with thrombin time, while positively correlated with D-dimer and urea levels. Lymphocytic miR-99a-5p levels were positively correlated with platelet mean volume and distribution width. CONCLUSION: This study demonstrated that miR-99a 5p levels in circulating immune cells might facilitate the diagnosis of ischemic stroke.

Carotid atherosclerosis is regarded as surrogate marker of coronary atherosclerosis. We aimed to know whether evaluation for carotid atherosclerosis should be done in all patients of NAFLD. MATERIALS AND METHODS: A total of 200 NAFLD patients and 100 age- and sex-matched controls were enrolled into the study. Ultrasound was done to document fatty liver and carotid intimal thickness, and relation between these two was observed. RESULTS: Grade 1 fatty liver was seen in 36% patients while Grade 2 fatty liver was found in 39% and Grade 3 fatty liver in 25%. Patients with Grade 1 fatty liver had left intima-media thickness (IMT) in the range of 0.4-0.6 mm (mean IMT - 0.69 mm) and had right IMT in the range of 0.5-0.8 mm (mean IMT - 0.71 mm). In patients with Grade 2 fatty liver, left IMT was in the range of 0.6-1.0 mm (mean IMT - 0.80 mm) and right IMT in the range of 0.7-1.0 mm (mean IMT - 0.84 mm), while in patients with Grade 3 fatty liver, left IMT was in the range of 0.8-1.2 mm (mean IMT - 0.93 mm) and right IMT in the range of 0.9-1.4 mm (mean IMT - 0.99 mm). Among controls, the mean left IMT was 0.579 mm and mean right IMT was 0.575 mm. CONCLUSION: The level of carotid intimomedial thickness was more in cases than in controls and progressively increased with the grade of fatty liver which was statistically significant. PMID- 30276298 TI - The role of hormesis in the functional performance and protection of neural systems. AB - This paper addresses how hormesis, a biphasic dose response, can protect and affect performance of neural systems. Particular attention is directed to the potential role of hormesis in mitigating age-related neurodegenerative diseases, genetically based neurological diseases, as well as stroke, traumatic brain injury, seizure, and stress-related conditions. The hormetic dose response is of particular significance since it mediates the magnitude and range of neuroprotective processes. Consideration of hormetic dose-response concepts can also enhance the quality of study designs, including sample size/statistical power strategies, selection of treatment groups, dose spacing, and temporal/repeat measures' features. PMID- 30276301 TI - Mortality in ischemic stroke score: A predictive score of mortality for acute ischemic stroke. AB - OBJECTIVE: This prospective study was planned to formulate and evaluate a predictive score for in-hospital mortality in cases of acute ischemic stroke. MATERIALS AND METHODS: In this study, 188 consecutive patients of ischemic stroke were included over 19 months. Only patients with renal failure and malignancy were excluded from the study. All patients were subjected to clinical evaluation along with Glasgow Coma Scale (GCS), National Institute of Health Science scale (NIHSS) score, and modified Rankin score (mRS). Investigations total leukocyte count (TLC), capillary blood sugar at admission, high-sensitivity C-reactive protein (HS-CRP), and troponin I, electrocardiogram, and neuroimaging were performed. The patients were followed up till their outcome in the hospital, and patients who expired were grouped as "mortality group" and the rest as "discharged group." One-way anova analysis was carried out among the significant parameters to identify independent predictors of mortality in cases of ischemic stroke. RESULTS: After statistical analysis, it was found that late presentation to the hospital, pyrexia (temperature >99F), low diastolic blood pressure at the time of admission, hypoxia (saturation of oxygen <94%), NIHSS score >15, mRS >3, GCS <8, hyperglycemia (random blood sugar >200 mg/dL), raised TLC, and HS-CRP (>10 mg/L) are positive predictive factors of mortality in cases of ischemic stroke. Based on the above findings, a simple and easily applicable mortality in ischemic stroke (MIS) score is developed. CONCLUSION: This MIS score system will help the clinicians in better management of the patient and improved counseling the relatives of patients with ischemic stroke. PMID- 30276304 TI - The cerebral circulation: The centrality of its function, the catastrophe of its failure. PMID- 30276305 TI - The cerebral circulation and cerebrovascular disease I: Anatomy. AB - In this paper, which is the first in a three-part series that reviews cerebrovascular anatomy, pathogenesis, and stroke, we lay the anatomical foundation for the rest of the series. Beginning with its origin in the branches of the aorta, we start by describing the arterial system. This system is partitioned into two major divisions (anterior and posterior circulations) that differ significantly in features and pathogenic potential. The systems, and the major branches that comprise them, are described. Description of the arterial system proceeds to the point of the fulfillment of its function. This function, the exchange of gases and nutrients with the cerebral parenchyma, is the subject of a subsequent section on the microcirculation and blood-brain barrier. Finally, the cerebral venous system, which is composed of cerebral veins and dural venous sinuses, is described. Thus, an anatomical context is supplied for the discussion of cerebrovascular disease pathogenesis provided by our second paper. PMID- 30276306 TI - The cerebral circulation and cerebrovascular disease II: Pathogenesis of cerebrovascular disease. AB - In this paper, we review the cerebral circulation and cerebrovascular disease (CVD) with an overview of the major types of CVD pathogenesis. These, as categorized here, are as follows: occlusive injury intrinsic to blood vessels, occlusive injury extrinsic to blood vessels, cerebral hypoperfusion, and cerebral hemorrhage. Following an overview of each of these categories, we conclude with a discussion of cerebral edema to illustrate how the pathological origins we covered can progress clinically. The content of this paper sets the stage for the detailed, clinically oriented discussion of stroke with which our series culminates in its subsequent Part III. PMID- 30276307 TI - The cerebral circulation and cerebrovascular disease III: Stroke. AB - In this paper, our review series on cerebrovascular disease anatomy, physiology, and pathology ends with a thorough discussion of the most significant cerebrovascular pathology: stroke. This discussion proceeds through two layers of organization. First, stroke is divided up into its main etiologic categories (ischemic stroke/transient ischemic attack, hemorrhagic stroke, and ischemic to hemorrhagic transformation). Then, the epidemiological, pathophysiological, clinical, and therapeutic (employed currently as well as emerging) aspects of each etiology are explored; emphasis is placed upon the therapeutic aspects. Finally, once we have covered all aspects of each etiologic category, we end our review with a defense of the thesis that there is much hope for the future of stroke treatment to be derived from familiarity with the literature on emerging therapies. PMID- 30276308 TI - Tackling issues in the path toward clinical translation in brain conditioning: Potential offered by nutraceuticals. AB - Brief periods of ischemia have been shown in many experimental setups to provide tolerance against ischemia in multiple organs including the brain, when administered before (preconditioning) or even after (postconditioning) the normally lethal ischemia. In addition to these so-called ischemic conditionings, many pharmacological and natural agents (e.g., chemicals and nutraceuticals) can also act as potent pre- and post-conditioners. Deriving from the original concept of ischemic preconditioning, these various conditioning paradigms may be promising as clinical-stage therapies for prevention of ischemic-related injury, especially stroke. As no proven experimentally identified strategy has translated into clinical success, the experimental induction of neuroprotection using these various conditioning paradigms has raised several questions, even before considering translation to clinical studies in humans. The first aim of the review is to consider key questions on preclinical studies of pre- or post conditioning modalities including those induced by chemical or nutraceuticals. Second, we make the argument that several key issues can be addressed by a novel concept, nutraceutical preconditioning. Specifically, alpha-linolenic acid (alpha linolenic acid [ALA] an omega-3 polyunsaturated fatty acid), contained in plant derived edible products, is essential in the daily diet, and a body of work has identified ALA as a pre- and post-conditioner of the brain. Nutritional intervention and functional food development are an emerging direction for preventing stroke damage, offering the potential to improving clinical outcomes through activation of the endogenous protective mechanisms known collectively as conditioning. PMID- 30276311 TI - Doppler sonographic assessment of carotid arteries in Sudanese stroke patients. AB - BACKGROUND: Hypertension, diabetes, and smoking were considered to be associated with several public health problems. OBJECTIVE: the study aims to explore the hemodynamic of carotid arteries in association with hypertension, diabetes, and smoking in Sudanese stroke patients. MATERIALS AND METHODS: In a quantitative descriptive study, fifty patients with stroke were scanned by B-mode and Doppler sonography. Carotid arteries were investigated with a 7-MHz linear transducer by a standard carotid sonography protocol. RESULTS: The average Doppler resistive index (RI) was 0.71 +/- 0.084 and intima-media thickness was 1.39 +/- 0.78 mm. The end diastolic velocities (EDVs) and peak systolic velocities (PSVs) of common carotid arteries were significantly changed in smokers and hypertensive (P < 0.05). The elevation of RI in right and left CCAs were significantly correlated with smokers (P = 0.017 and 0.010 respectively). Hemorrhagic stroke was most prevalent in hypertensive rather than diabetic and smokers. The carotid hemodynamics changed significantly in hypertensive and smokers more than diabetics. CONCLUSION: EDV and PSV were significantly correlated with hypertension and tobacco smoking rather than diabetes. Hypertension, diabetes, and smoking have an association with stroke and hand significant effect on carotid artery hemodynamic and atherosclerotic disease. The Doppler RIs were significantly correlated with smokers. Patients with risk factors of stroke should be scanned with Doppler sonography as early as possible. PMID- 30276312 TI - Recent progress in regenerative medicine for brain disorders. PMID- 30276310 TI - Targeting G protein-coupled receptor for pain management. AB - Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage. Great progress has been made in understanding the important roles of various G protein-coupled receptors in the regulation of pain transmission. However, many important questions remain uncertain about the precise signal transduction mechanisms. This review focuses opioid receptor and CXC receptor 4 on the effects and mechanisms of pain. Taken together, chemokines and their receptors are potential targets for the development of novel pain management and therapy. PMID- 30276313 TI - Limiting exercise inhibits neuronal recovery from neurological disorders. AB - Patients who are bedridden often suffer from muscular atrophy due to reduced daily activities and can become depressed. However, patients who undergo physical therapy sometimes demonstrate positive benefits including a reduction of stressful and depressed behavior. Regenerative medicine has seen improvements in two stem cell-based therapies for central nervous system disorders. One therapy is through the transfer of exogenous stem cells. The other therapy is a more natural method and focuses on the increasing endogenous neurogenesis and restoring the neurological impairments. This study overviews how immobilization induced disuse atrophy affects neurogenesis in rats, specifically hypothesizing that immobilization diminishes circulating trophic factor levels, like vascular endothelial growth factors or brain-derived neurotrophic factor, which in turn limits neurogenesis. This hypothesis requires the classification of the stem cell microenvironment by probing growth factors in addition to other stress-related proteins that correlate with exercise-induced neurogenesis. There is research examining the effects of increased exercise on neurogenesis while limiting exercise, which better demonstrates the pathological states of immobile stroke patients, remains relatively unexplored. To examine the effects of immobilization on neurogenesis quantitative measurements of movements, 5-bromo-2deoxyuridine labeling of proliferative cells, biochemical assays of serum, cerebrospinal fluid and neurological levels of trophic factors, growth factors, and stress-related proteins will indicate levels of neurogenesis. In further research, studies are needed to show how in vivo stimulation, or lack thereof, affects stem cell microenvironments to advance treatment procedures for strengthening neurogenesis in bedridden patients.

PMID- 30276314 TI - Exogenous stem cells pioneer a biobridge to the advantage of host brain cells following stroke: New insights for clinical applications. AB - Stroke continues to maintain its status as one of the top causes of mortality within the United States. Currently, the only Food and Drug Administration (FDA) approved drug in place for stroke patients, tissue plasminogen activator (tPA), has a rigid therapeutic window, closing at approximately 4.5 h after stroke onset. Due to this short time frame and other restrictions, such as any condition that increases a patient's risk for hemorrhaging, it has been predicted that <5% of ischemic stroke patients benefit from tPA. Given that rehabilitation therapy remains the only other option for stroke victims, there is a clear unmet clinical need for treatment available for the remaining 95%. While still considered an experimental treatment, the utilization of stem cell therapies for stroke holds consistent promise. Copious preclinical studies report the capacity for transplanted stem cells to rescue the brain parenchyma surrounding the stroke induced infarct core. At present, the exact mechanisms in which stem cells contribute a robust therapeutic benefit remains unclear. Following stem cell administration, researchers have observed cell replacement, an increase in growth factors, and a reduction in inflammation. With a deeper understanding of the precise mechanism of stem cells, these therapies can be optimized in the clinic to afford the greatest therapeutic benefit. Recent studies have depicted a unique method of endogenous stem cell activation as a result of stem cell therapy. In both traumatic brain injury and stroke models, transplanted mesenchymal stromal cells (MSCs) facilitated a pathway between the neurogenic niches of the brain and the damaged area through extracellular matrix remodeling. The biobridge pioneered by the MSCs was utilized by the endogenous stem cells, and these cells were able to travel to the damaged areas distal to the neurogenic niches, a feat unachievable without prior remodeling. These studies broaden our understanding of stem cell interactions within the injured brain and help to guide both researchers and clinicians in developing an effective stem cell treatment for stroke.

PMID- 30276309 TI - Prospective clinical biomarkers of caspase-mediated apoptosis associated with neuronal and neurovascular damage following stroke and other severe brain injuries: Implications for chronic neurodegeneration. AB - Acute brain injuries, including ischemic and hemorrhagic stroke, as well as traumatic brain injury (TBI), are major worldwide health concerns with very limited options for effective diagnosis and treatment. Stroke and TBI pose an increased risk for the development of chronic neurodegenerative diseases, notably chronic traumatic encephalopathy, Alzheimer's disease, and Parkinson's disease. The existence of premorbid neurodegenerative diseases can exacerbate the severity and prognosis of acute brain injuries. Apoptosis involving caspase-3 is one of the most common mechanisms involved in the etiopathology of both acute and chronic neurological and neurodegenerative diseases, suggesting a relationship between these disorders. Over the past two decades, several clinical biomarkers of apoptosis have been identified in cerebrospinal fluid and peripheral blood following ischemic stroke, intracerebral and subarachnoid hemorrhage, and TBI. These biomarkers include selected caspases, notably caspase-3 and its specific cleavage products such as caspase-cleaved cytokeratin-18, caspase-cleaved tau, and a caspase-specific 120 kDa alphaII-spectrin breakdown product. The levels of these biomarkers might be a valuable tool for the identification of pathological pathways such as apoptosis and inflammation involved in injury progression, assessment of injury severity, and prediction of clinical outcomes. This review focuses on clinical studies involving biomarkers of caspase-3-mediated pathways, following stroke and TBI. The review further examines their prospective diagnostic utility, as well as clinical utility for improved personalized treatment of stroke and TBI patients and the development of prophylactic treatment chronic neurodegenerative disease. PMID- 30276315 TI - Neuroinflammation in traumatic brain injury: A chronic response to an acute injury. AB - Every year, approximately 1.4 million US citizens visit emergency rooms for traumatic brain injuries. Formerly known as an acute injury, chronic neurodegenerative symptoms such as compromised motor skills, decreased cognitive abilities, and emotional and behavioral changes have caused the scientific community to consider chronic aspects of the disorder. The injury causing impact prompts multiple cell death processes, starting with neuronal necrosis, and progressing to various secondary cell death mechanisms. Secondary cell death mechanisms, including excitotoxicity, oxidative stress, mitochondrial dysfunction, blood-brain barrier disruption, and inflammation accompany chronic traumatic brain injury (TBI) and often contribute to long-term disabilities. One hallmark of both acute and chronic TBI is neuroinflammation. In acute stages, neuroinflammation is beneficial and stimulates an anti-inflammatory response to the damage. Conversely, in chronic TBI, excessive inflammation stimulates the aforementioned secondary cell death. Converting inflammatory cells from pro inflammatory to anti-inflammatory may expand the therapeutic window for treating TBI, as inflammation plays a role in all stages of the injury. By expanding current research on the role of inflammation in TBI, treatment options and clinical outcomes for afflicted individuals may improve. This paper is a review article.

AB - Cell death and neurogenesis have been examined after stroke in the subventricular zone of the adult mammalian brain. New research focuses on the use of drugs to improve the viability of neural progenitor cells in rats after stroke. The aim of the drugs is to lengthen the timeframe for stroke therapy by targeting the endogenous repair mechanism that follows injury. In this paper, we look at the broad state of stroke therapy to assess the effectiveness of endogenous neurogenesis-enhancing drugs on stroke. This paper is a review article.

PMID- 30276316 TI - Granulocyte-colony stimulating factor and umbilical cord blood cell transplantation: Synergistic therapies for the treatment of traumatic brain injury. AB - Traumatic brain injury (TBI) is now characterized as a progressive, degenerative disease and continues to stand as a prevalent cause of death and disability. The pathophysiology of TBI is complex, with a variety of secondary cell death pathways occurring which may persist chronically following the initial cerebral insult. Current therapeutic options for TBI are minimal, with surgical intervention or rehabilitation therapy existing as the only viable treatments. Considering the success of stem-cell therapies in various other neurological diseases, their use has been proposed as a potential potent therapy for patients suffering TBI. Moreover, stem cells are highly amenable to adjunctive use with other therapies, providing an opportunity to overcome the inherent limitations of using a single therapeutic agent. Our research has verified this additive potential by demonstrating the efficacy of co-delivering human umbilical cord blood (hUCB) cells with granulocyte-colony stimulating factor (G-CSF) in a murine model of TBI, providing encouraging results which support the potential of this approach to treat patients suffering from TBI. These findings justify ongoing research toward uncovering the mechanisms which underlie the functional improvements exhibited by hUCB + G-CSF combination therapy, thereby facilitating its safe and effect transition into the clinic.

PMID- 30276318 TI - Translating regenerative medicine techniques for the treatment of epilepsy. AB - Epilepsy is considered a chronic neurological disorder and is accompanied by persistent and diverse disturbances in electrical brain activity. While antiepileptic pharmaceuticals are still the predominant treatment for epilepsy, the advent of numerous surgical interventions has further improved outcomes for patients. Despite these advancements, a subpopulation continues to experience intractable seizures which are resistant to current conventional and nonconventional therapeutic options. In this review, we begin with an introduction to the clinical presentation of epilepsy before discussing the clinically relevant laboratory models of epilepsy. Finally, we explore the implications of regenerative medicine - including cell therapy, neuroprotective agents, and electrical stimulation - for epilepsy, supplemented with our laboratory's data.

PMID- 30276319 TI - Endogenous repair mechanisms enhanced in Parkinson's disease following stem cell therapy. AB - This mini-review highlights the innovative observation that transplanted human neural stem cells can bring about endogenous brain repair through the stimulation of multiple regenerative processes in the neurogenic area (i.e., subventricular zone [SVZ]) in an animal model of Parkinson's disease (PD). In addition, we convey that identifying anti-inflammatory cytokines, therapeutic proteomes, and neurotrophic factors within the SVZ may be essential to induce brain repair and behavioral recovery. This work opens up a new area of research for further understanding the pathology and treatment of PD. This paper is a review article.

AB - The ability of stem cells to differentiate into various lineages has made them powerful tools of regenerative medicine and applicable to multiple human diseases. Of particular interest, amniotic fluid-derived stem cells (AFSC) have been characterized to express both adult and embryonic cell markers, indicating them as cells within an intermediate stage between embryonic and adult phenotype. AFSC can differentiate into cells of all three germ layers, including hepatic, myogenic, osteogenic, and neurogenic cell types. Furthermore, AFSC have minimal replicative senescence, retaining the ability to divide effectively for over 250 doublings. These facts indicate that amniotic fluid may exist as a promising donor source of stem cells for the treatment of multiple clinically relevant conditions. Of particular interest is the convenience of harvesting stem cells from the amniotic fluid stem for the treatment of newborns, as well as for banking or cryopreserving purposes to be used at a later date. Importantly, the promise of amniotic fluid as a source of stem cells merits ongoing research into their potential therapeutic applications. This paper is a review article.

PMID- 30276320 TI - Amniotic fluid stem cell models: A tool for filling the gaps in knowledge for human genetic diseases. AB - Induced pluripotent stem (iPS) cells have attracted attention in recent years as a model of human genetic diseases. Starting from the diseased somatic cells isolated from an affected patient, iPS cells can be created and subsequently differentiated into various cell types that can be used to gain a better understanding of the disease at a cellular and molecular level. There are limitations of iPS cell generation, however, due to low efficiency, high costs, and lengthy protocols. The use of amniotic fluid stem cells (AFS) presents a worthy alternative as a stem cell source for modeling of human genetic diseases. Prenatal identification of chromosomal or Mendelian diseases may require the collection of amniotic fluid which is not only useful for the sake of diagnosis but also from this, AFS cells can be isolated and cultured. Since AFS cells show some characteristics of pluripotency, having the capacity to differentiate into various cell types derived from all three germ layers in vitro, they are a well suited model for investigations regarding alterations in the molecular biology of a cell due to a specific genetic disease. This readily accessible source of stem cells can replace the necessity for generating iPS cells. Here, we expand on the applicability and importance of AFS cells as a model for discovery in the field of human genetic disease research. This paper is a review article.

PMID- 30276322 TI - Colony stimulating factor-1 receptor as a treatment for cognitive deficits postfractionated whole-brain irradiation. AB - Whole-brain irradiation (WBI) is commonly used to treat primary tumors of the central nervous systems tumors as well as brain metastases. While this technique has increased survival among brain tumor patients, the side effects of including a decline in cognitive abilities that are generally progressive. In an effort to combat WBI side effects, researchers explored the treatment of colony stimulating factor-1 receptor (CSF-1R) inhibitor. Data show that when a CSF-1R inhibitor is administered with fractionated WBI treatment, there is a decline in the number of resident and peripheral mononuclear phagocytes, a decrease in dendritic spine loss and a reduction in functional and memory deficits. CSFR-1R inhibitors have displayed promising results as an effective counter-treatment for WBI-induced deficits. Further research is required to optimize treatment strategies, establish a treatment timeline and gain a better understanding of the long-term side effects of targeting CSF-1R as a treatment strategy for WBI symptoms.

PMID- 30276325 TI - A focus on CXCR4 in Alzheimer's disease. AB - Alzheimer's disease (AD) is one of the most common and devastating aging-related neurodegenerative diseases. Besides the well-known role of chemokines and their receptors in the immune system, they are widely expressed in the nervous system, where they play roles in the regulation of cell migration and neurotransmission. The chemokine CXC motif receptor 4 (CXCR4) is evolutionarily highly conserved seven-transmembrane G-protein-coupled receptors (GPCRs). It has been demonstrated that CXCL12/CXCR4 signaling pathway involved in the pathologic process of AD. In this review, we demonstrated the GPCR family proteins and summarized the relationship between CXCR4 and GPCR, CXCR4 and AD. The review aimed to provide the novel insight of CXCR4 into the early prevention of mild cognitive impairment and in the diagnosis and treatment of AD. PMID- 30276326 TI - Enhanced oxidative stress response and neuroprotection of combined limb remote ischemic conditioning and atorvastatin after transient ischemic stroke in rats. AB - BACKGROUND: Limb remote ischemic conditioning (LRIC) and atorvastatin (AtS) both provide neuroprotection in stroke. We evaluated the enhanced neuroprotective effect of combining these two treatments in preventing ischemia/reperfusion (I/R) induced cerebral injury in a rat model and investigated the corresponding molecular mechanisms. MATERIALS AND METHODS: Transient cerebral ischemia was induced in Sprague-Dawley male rats by middle cerebral artery occlusion (MCAO) for 90 min followed by reperfusion (I/R). Rats were divided into 5 groups, sham, I/R, I/R + AtS, I/R + LRIC and I/R + AtS + LRIC. Pretreatment with LRIC and/or AtS for 14 days before MCAO surgery. Infarct volume, neurological score, Western blot, immuno-histochemical analyses were performed. RESULTS: The combination of LRIC plus AtS pretreatment decreased infarct volume and inhibited neuronal apoptosis. Combination treatment achieved stronger neuroprotection than monotherapy with LRIC or AtS. These therapies reduced reactive oxygen species production in the peri-ischemia region, associated with significantly increased expression and activation of superoxide dismutase 1, hemeoxygenase 1 and nuclear factor erythroid 2-related factor 2. CONCLUSIONS: Both LRIC and AtS + LRIC treatments conferred neuroprotection in ischemic stroke by reducing brain oxidative stress. AtS plus LRIC is an attractive translational research option due to its ease of use, tolerability, economical, and tremendous neuroprotective potential in stroke. PMID- 30276327 TI - Safety and efficacy of remote ischemic conditioning in pediatric moyamoya disease patients treated with revascularization therapy. AB - BACKGROUND: Revascularization surgery has been the standard treatment to prevent ischemic stroke in pediatric Moyamoya disease (MMD) patients with ischemic symptoms. However, perioperative complications, such as hyperperfusion syndrome, new infarct on imaging, or ischemic stroke, are inevitable. Remote ischemic conditioning (RIC) is a noninvasive and easy-to-use neuroprotective strategy, and it has potential effects on preventing hyperperfusion syndrome and ischemic infarction. AIMS: The aim of this study is to investigate the safety and efficacy of RIC in pediatric MMD patients undergoing revascularization surgery. METHOD: A total of 60 pediatric MMD patients with one or more ischemic symptoms will be recruited and allocated in 1:1 ratio to the RIC group and sham group, respectively. Both RIC and sham RIC will be performed twice daily for 7 consecutive days before revascularization surgery with different cuff pressures during the ischemia period (50 mmHg over-systolic blood pressure and 30 mmHg). Single photon emission computed tomography will be performed within 7 days preoperatively and 3 months postoperatively, respectively, to evaluate the cerebral perfusion status. Other outcomes, including safety, plasma biomarker, functional outcome, and the incidence of infarction and its size, will also be evaluated. CONCLUSION: This study will provide insights into the preliminary proof of principle, safety, and efficacy of RIC in pediatric MMD patients undergoing revascularization surgery therapy, and this data will provide parameters for future larger scale clinical trials if efficacious. PMID- 30276324 TI - Therapeutic hypothermia and targeted temperature management for traumatic brain injury: Experimental and clinical experience. AB - Traumatic brain injury (TBI) is a worldwide medical problem, and currently, there are few therapeutic interventions that can protect the brain and improve functional outcomes in patients. Over the last several decades, experimental studies have investigated the pathophysiology of TBI and tested various pharmacological treatment interventions targeting specific mechanisms of secondary damage. Although many preclinical treatment studies have been encouraging, there remains a lack of successful translation to the clinic and no therapeutic treatments have shown benefit in phase 3 multicenter trials. Therapeutic hypothermia and targeted temperature management protocols over the last several decades have demonstrated successful reduction of secondary injury mechanisms and, in some selective cases, improved outcomes in specific TBI patient populations. However, the benefits of therapeutic hypothermia have not been demonstrated in multicenter randomized trials to significantly improve neurological outcomes. Although the exact reasons underlying the inability to translate therapeutic hypothermia into a larger clinical population are unknown, this failure may reflect the suboptimal use of this potentially powerful therapeutic in potentially treatable severe trauma patients. It is known that multiple factors including patient recruitment, clinical treatment variables, and cooling methodologies are all important in yielding beneficial effects. High quality multicenter randomized controlled trials that incorporate these factors are required to maximize the benefits of this experimental therapy. This article therefore summarizes several factors that are important in enhancing the beneficial effects of therapeutic hypothermia in TBI. The current failures of hypothermic TBI clinical trials in terms of clinical protocol design, patient section, and other considerations are discussed and future directions are emphasized. PMID- 30276329 TI - Cerebral venous sinus thrombosis: A diagnostic challenge in a rare presentation. AB - Cerebral venous sinus thrombosis (CVST) is an uncommon, life-threatening condition with a variable clinical presentation that makes it a challenge of diagnosis. A 39-year-old male patient presented to the hospital with complete loss of conscious and admitted to Medical Intensive Care Unit for investigation without any obvious history that was difficult for diagnosis. In this case, the patient presented with coma that is a rare presentation of CVST with no obvious clinical history and he was male patient that means he is free of all gender specific risk factors of CVST. The brain computed tomography (CT) scan showed hypodense lesion in the left upper parietal region with no hemorrhage. The lesion was low-signal intensity (SI) on T1WIs and high SI on T2WIs and restricted on diffusion-weighted images like arterial infarctions, but magnetic resonance angiography (MRA) was normal that excluded arterial infarction. Gadolinium enhanced MR venography (MRV) showed the filling defect of CVST. CVST can be present by a mysterious clinical presentation that makes it as a challenge of diagnosis even by medical imaging by CT and MR imaging (MRI). A combination of MRI and MRV is the best, noninvasive, and nonionizing imaging modality for the diagnosis of CVST. PMID- 30276328 TI - Mild therapeutic hypothermia protects against cerebral ischemia/reperfusion injury by inhibiting miR-15b expression in rats. AB - OBJECTIVE: Mild hypothermia has a protective effect on ischemic stroke, but the mechanisms remain elusive. Here, we investigated microRNA (miRNA) profiles and the specific role of miRNAs in ischemic stroke treated with mild hypothermia. MATERIALS AND METHODS: Male adult Sprague Dawley rats were subjected to focal transient cerebral ischemia. Mild hypothermia was induced by applying ice packs around the neck and head of the animals. miRNAs expression profiles were detected in ischemic stroke treated with mild therapeutic hypothermia through miRNA chips. Reverse transcription-polymerase chain reaction (RT-PCR) was used to verify the change of miRNA array. Western blot and adenosine triphosphate (ATP) assay kits were used to detect the changes of protein expression and ATP levels, respectively. miR-15b mimic and its control were injected into the right lateral ventricle 60 min before the induction of ischemia. RESULTS: The results showed that mild hypothermia affected miRNAs profiles expression. We verified the expression of miR-15b and miR-598-3p by miRNA RT-PCR. miR-15b mimic inhibited the expression of its target, ADP ribosylation factor-like 2 (Arl2) protein, and decreased ATP levels in PC12 cells. Compared with the control, miR-15b mimic increased the infarct volume and aggravated the neurological function under normothermia or hypothermia treatment. Furthermore, the expression of Arl2 was decreased in the miR-15b mimic group under normothermia or hypothermia treatment. CONCLUSIONS: Mild therapeutic hypothermia affected miRNA profiles and protected against cerebral ischemia/reperfusion by inhibiting miR-15b expression in rats. miR-15b may be a potential target for therapeutic intervention in stroke. PMID- 30276331 TI - Cerebrospinal fluid circulation: What do we know and how do we know it? AB - The central nervous system's (CNS) complicated design is a double-edged sword. On the one hand, the complexity is what gives rise to higher order thinking; but on the other hand, damage to the CNS evokes its unforgiving nature. The cerebrospinal fluid (CSF) circulation system is an intricate system embedded in and around the CNS that has been the topic of debate since it was first described in the 18th century. It is underscored by the choroid plexus's distinct vascular network which has conventionally been seen as the most prominent structure in CSF production through a variety of active transporters and channels. Despite the ubiquity of this circulation system in vertebrates, some aspects remain understudied. Recent advances in scientific methodology and experimentation have proven to be effective tools for elucidating the mechanisms of the CSF circulation system and the pathological conditions associated with its malfunction. In this review, we capitulate the classical understanding of CSF physiology as well as a new, emerging theory on CSF production. PMID- 30276332 TI - Mid A1 blister aneurysm presenting with subarachnoid hemorrhage: Case report and review. AB - Blister aneurysms are uncommon and difficult-to-treat lesions. They are a substantial cause of morbidity and mortality when encountered. Here, we report a blister aneurysm of the mid A1 segment of the anterior cerebral artery presenting with diffuse basal subarachnoid hemorrhage (SAH). The aneurysm was treated by surgical clipping of the parent vessel. Postoperatively, there was no filling of the parent vessel or aneurysm. A treatment algorithm including direct surgical repair and flow diversion for ruptured blister aneurysms is described. A high level of suspicion should be maintained in the setting of angiographic-negative SAH with an asymmetrically diffuse pattern. PMID- 30276333 TI - Neuroprotective effects of tenuigenin on neurobehavior, oxidative stress, and tau hyperphosphorylation induced by intracerebroventricular streptozotocin in rats. AB - BACKGROUND: Tenuigenin (TEN), a major active component of the Chinese herb Polygala tenuifolia root, has been used to improve memory and cognitive function in Traditional Chinese Medicine for centuries. PURPOSE: The present study was designed to explore the possible neuroprotective effect of TEN on the streptozotocin (STZ)-induced rat model of sporadic Alzheimer's disease (sAD). METHODS: STZ was injected twice intracerebroventrically (3 mg/kg, ICV) on alternate days (day 1 and day 3) in Rats. Daily treatment with TEN (2, 4, and 8 mg/kg) starting from the first dose of STZ for 28 days. Memory-related behaviors were evaluated using the Morris water maze test. Hyperphosphorylation of tau proteins in hippocampus were measured by western blot assay. Superoxide dismutase activities, malondialdehyde, glutathione peroxidase and 4-hydroxy-2-nonenal adducts contents were also measured in the hippocampus. RESULTS: Treatment with TEN significantly improved STZ-induced cognitive damage, markedly reduced changes in malondialdehyde and 4-hydroxy-2-nonenal adducts, and significantly inhibited STZ-induced reduction in superoxide dismutase and glutathione peroxidase activities in the hippocampus. In addition, TEN decreased hyperphosphorylation of tau resulting from intracerebroventricular STZ (ICV-STZ) injection, and Nissl staining results showed that TEN has protective effects on hippocampal neurons. CONCLUSION: These results provide experimental evidence demonstrating preventive effect of TEN on cognitive dysfunction, oxidative stress, and hyperphosphorylation of tau in ICV-STZ rats. This study indicates that TEN may have beneficial effects in the treatment of neurodegenerative disorders such as AD. PMID- 30276334 TI - The association between the ring finger protein 213 gene R4810K variant and intracranial major artery stenosis/occlusion in the Han Chinese population and high-resolution magnetic resonance imaging findings. AB - BACKGROUND AND PURPOSE: The ring finger protein 213 (RNF213) gene R4810K variant, a susceptibility locus for moyamoya disease (MMD), has recently been identified to be associated with intracranial major artery stenosis/occlusion (ICASO) without satisfying the diagnostic criteria of MMD in the Japanese population. However, further studies are needed to determine whether this variant is associated with ICASO in other populations and whether R4810K variant-related ICASO could be categorized as MMD. The aim of this study is to elucidate whether the R4810K variant was associated with ICASO among the Han Chinese population and potential histopathology of R4810K variant-related ICASO. MATERIALS AND METHODS: We conducted a case-control study to evaluate association and performed high resolution (HR) magnetic resonance imaging (MRI) to investigate arterial wall feature of ICASO. The R4810K variant was genotyped in 114 ICASO patients and 268 controls. Then, patients with R4810K variant-related ICASO were subjected to HR MRI examination and presumptively diagnosed based on the characteristics thus observed. STATISTICAL ANALYSIS: The relationship between R4810K variant and ICASO was evaluated by Fisher's exact test with odds ratios (OR) and 95% confidence interval (CI). RESULTS: The R4810K variant was associated with ICASO and increased the risk for ICASO (P < 0.01; OR: 20.2; 95% CI: 2.5-163.11). Presumptive MMD was diagnosed in all female patients with R4810K variant. However, presumptive intracranial atherosclerotic stenosis was diagnosed in one of three males harboring this variant. CONCLUSIONS: The R4810K variant is a genetic risk factor for ICASO among the Han Chinese population and that R4810K variant-related ICASO should be identified as MMD in female but not uncertain in male patients.

AB - The cessation (ischemia) and restoration (reperfusion) of cerebral blood flow after cardiac arrest (CA) induce inflammatory processes that can result in additional brain injury. Therapeutic hypothermia (TH) has been proven as a brain protective strategy after CA. In this article, the underlying pathophysiology of ischemia-reperfusion brain injury with emphasis on the role of inflammatory mechanisms is reviewed. Potential targets for immunomodulatory treatments and relevant effects of TH are also discussed. Further studies are needed to delineate the complex pathophysiology and interactions among different components of immune response after CA and identify appropriate targets for clinical investigations. PMID- 30276337 TI - Effects of ischemic preconditioning on mitochondrial and metabolic neruoprotection: 5' adenosine monophosphate-activated protein kinase and sirtuins. AB - Stroke and cardiac arrest result in cerebral ischemia, a highly prevalent medical issue around the world, which is characterized by a reduction or loss of blood flow to the brain. The loss of adequate nutrient supply in the brain during ischemia results in neuronal cell death contributing to cognitive and motor deficits that are usually permanent. Current effective therapies for cerebral ischemia are only applicable after the fact. Thus, the development of preventative therapies of ischemia is imperative. A field of research that continues to show promise in developing therapies for cerebral ischemia is ischemic preconditioning (IPC). IPC is described as exposure to sublethal ischemic events, which induce adaptive changes that provide tolerance to future ischemic events. Through either transient sub-lethal ischemic events, or the actions of a preconditioning molecular mimetic, IPC typically results in augmented gene expression and cellular metabolism. A pivotal target of such changes in gene expression and metabolism is the mitochondrion. Direct and indirect effects on mitochondria by IPC can result in the activation of 5' adenosine monophosphate-activated protein kinase (AMPK), a master regulator of cellular metabolism. Changes in the activity of the posttranslational modifiers, SIRT1 and SIRT5, also contribute to the overall adaptive processes in cellular metabolism and mitochondrial functioning. In this review, we present recently collected evidence to highlight the neuroprotective interactions of mitochondria with AMPK, SIRT1, and SIRT5 in IPC. To produce this review, we utilized PubMed and previous reviews to target and to consolidate the relevant studies and lines of evidence. PMID- 30276338 TI - Low-temperature plasma radiofrequency ablation in phantom limb pain: A case report. AB - Phantom limb pain (PLP) and phantom limb sensations are common complications postamputation. PLP is defined as persistent painful sensations perceived in the missing portion of the amputated limb. Low-temperature plasma radiofrequency ablation (coblation) technology is a relatively new technology that has shown promise in treating neuropathic pain. This report illustrates the use of coblation technology on cervical nerve roots for PLP. Coblation of the cervical nerve root was performed. Three 17G puncture trocars were placed near the C5-C6, C6-C7, and C7-T1 intervertebral foramen with computed tomography (CT) guidance. Then, a coblation needle attached to low-temperature plasma multifunctional operation system was placed near the C8 nerve root through the puncture trocars. To locate the target nerve, single stimulation (lasting for 5 s, at 1 intensity) in "cut" and "coagulation" model was given to serve as a sensory stimulation test. The stimulation induced radiating pain of the stimulated nerve away from the stimulation site to confirm our target nerve. The needle location was redirected based on the reproduction of the patient's symptoms with minimal intensity. A CT-guided cervical nerve root coblation was performed to obtain longer PLP relief. The patient reported pain relief in PLP after the operation. At 1-, 3-, and 6-month postoperative review, PLP relief was achieved. Overall activity was improved and there was necessarily need for pain medications. However, the doses of medicine significantly decreased. The analgesic effect was stable during the 6-month follow-up period. Our report demonstrates that coblation technology is successful treatment for PLP in this case. It will supply us a novel navigation in PLP treatments. Meanwhile, this finding still needs additional study for confirmation. PMID- 30276336 TI - Cerebrovascular dysfunction with stress and depression. AB - Maintenance of adequate tissue perfusion through a dense network of cerebral microvessels is critical for the perseveration of normal brain function. Regulation of the cerebral blood flow has to ensure adequate delivery of nutrients and oxygen with moment-to-moment adjustments to avoid both hypo- and hyper-perfusion of the brain tissue. Even mild impairments of cerebral blood flow regulation can have significant implications on brain function. Evidence suggests that chronic stress and depression elicits multifaceted functional impairments to the cerebral microcirculation, which plays a critical role in brain health and the pathogenesis of stress-related cognitive impairment and cerebrovascular events. Identifying the functional and structural changes to the brain that are induced by stress is crucial for achieving a realistic understanding of how related illnesses, which are highly disabling and with a large economic cost, can be managed or reversed. This overview discusses the stress-induced alterations in neurovascular coupling with specific attention to cerebrovascular regulation (endothelial dependent and independent vasomotor function, microvessel density). The pathophysiological consequences of cerebral microvascular dysfunction with stress and depression are explored. PMID- 30276339 TI - Multifocal cerebral infarction as the first manifestation of occult malignancy: Case series of trousseau's syndrome and literature review. AB - Ischemic stroke as an initial presentation of malignancy is extremely rare and the underlying etiology is often ignored. The aim of this study is to outline the clues to occult malignancy in patients presenting with cerebral infarction initially. The clinical characteristics of total 19 patients with Trousseau's Syndrome presenting with cerebral infarction initially were analyzed. Among those patients, no conventional vascular risk factors were detected in 68% (13/19) of patients, and infarction occurring in multiple vascular distributions was found in 84% (16/19). Blood test showed thrombophilia in 79% (15/19) of patients with significantly elevated D-dimer, disseminated intravascular coagulopathy (DIC) in 59% (11/19), and elevated levels of tumor makers in 47% (9/19). The prognosis of the 19 patients was poor, with 68% (13/19) of patients undergoing a relapse of stroke in short interval, and 84% (16/19) being reportedly to die in 6 months. In patients, who developed unexplained recurrent brain infarction involving multiple arterial territory, with laboratory evidence suggesting hypercoagulability (higher level of D-dimer, or DIC), Trousseau's Syndrome should be considered, and investigation for an occult malignancy was required.

AB - Background: Acute appendicitis is one of the most common acute surgical emergencies in children and accounts for an annual cost of approximately L50 million to the National Health Service. Investigating alternative treatment options offers the best prospect of enhancing the quality of care for patients and potential opportunities for cost savings through better allocative efficiency. A feasibility randomised controlled trial (RCT) comparing a non operative treatment pathway with appendicectomy for children with acute uncomplicated appendicitis is underway (CONTRACT feasibility RCT). Aims: The prime objective of this economic substudy conducted alongside the CONTRACT feasibility RCT is to better understand and assess: (1) cost data collection tools and cost drivers by identifying patients' pathways and (2) patient quality of life by assessing alternative paediatric health-related quality of life (HRQoL) instruments. Outcomes from this study will inform a future efficacy RCT assessing the effectiveness and cost-effectiveness of non-operative treatment pathway for the treatment of acute uncomplicated appendicitis in children. Methods: The economic substudy will use individual-level data and will be conducted from the health system perspective over the study's 6-month follow-up period. Microcosting will include health resource and service use, while potential benefits acquired will be measured using the HRQoL measures, Child Health Utility 9D (CHU-9D) and Euroqol-5 dimensions and 5 levels (EQ-5D-5L). We will assess the appropriateness of using the cost per quality-adjusted life year framework in the future RCT, as well as testing and identifying the most suitable HRQoL instrument. Conclusions: The outcomes of the investigational economic substudy will be used to inform the design of our future definitive RCT. However, the result from this economic study will also provide a detailed description and account of the issues inherent in paediatric Economic Evaluations Alongside Clinical Trials with an emphasis on costing methods of interventions taking place in secondary care settings.

AB - The recent evolution in immunosuppression therapy has led to significant improvement in short-term kidney allograft outcomes; however, this progress did not translate into similar improvement in long-term graft survival. The latter, at least in part, is likely to be attributed to immunosuppressant side effects. In this review, we focus on the histologic manifestations of calcineurin inhibitor and mammalian target of rapamycin inhibitor toxicity. We discuss the pathologic features attributed to such toxicity and allude to the lack of highly specific pathognomonic lesions. Finally, we highlight the importance of clinicopathologic correlation to achieve a meaningful pathologic interpretation.

AB - Monocytes and macrophages are critical components of the myeloid niche of the innate immune system. In addition to traditional roles as phagocytes, this subsection of innate immunity has been implicated in its ability to regulate tissue homeostasis and inflammation across diverse physiological systems. Recent emergence of discriminatory features within the monocyte/macrophage niche within the last 5 years has helped to clarify specific function(s) of the subpopulations of these cells. It is becoming increasingly aware that these cells are likely implicated in valve development and disease. This review seeks to use current literature and opinions to show the diverse roles and potential contributions of this niche throughout valvulogenic processes, adult homeostatic function, valve disease mechanisms, and tissue engineering approaches. PMID- 30276358 TI - Biomechanical forces in tissue engineered tumor models. AB - Solid tumors are complex three-dimensional (3D) networks of cancer and stromal cells within a dynamic extracellular matrix. Monolayer cultures fail to recapitulate the native microenvironment and therefore are poor candidates for pre-clinical drug studies and studying pathways in cancer. The tissue engineering toolkit allows us to make models that better recapitulate the 3D architecture present in tumors. Moreover, the role of the mechanical microenvironment, including matrix stiffness and shear stress from fluid flow, is known to contribute to cancer progression and drug resistance. We review recent developments in tissue engineered tumor models with a focus on the role of the biomechanical forces and propose future considerations to implement to improve physiological relevance of such models. PMID- 30276359 TI - Evaluation of Peak Reflux Velocities with Vector Flow Imaging and Spectral Doppler Ultrasound in Varicose Veins. AB - Purpose Spectral Doppler ultrasound (SDUS) is used for quantifying reflux in lower extremity varicose veins. The technique is angle-dependent opposed to the new angle-independent Vector Flow Imaging (VFI) method. The aim of this study was to compare peak reflux velocities obtained with VFI and SDUS in patients with chronic venous disease, i. e., pathological retrograde blood flow caused by incompetent venous valves. Materials and Methods 64 patients with chronic venous disease were scanned with VFI and SDUS in the great or the small saphenous vein, and reflux velocities were compared to three assessment tools for chronic venous disease. A flow rig was used to assess the accuracy and precision of the two methods. Results The mean peak reflux velocities differed significantly (VFI: 47.4 cm/s vs. SDUS: 62.0 cm/s, p<0.001). No difference in absolute precision (p=0.18) nor relative precision (p=0.79) was found. No correlation to disease severity, according to assessment tools, was found for peak reflux velocities obtained with either method. In vitro, VFI was more accurate but equally precise when compared to SDUS. Conclusion Both VFI and SDUS detected the pathologic retrograde flow in varicose veins but measured different reflux velocities with equal precision. VFI may play a role in evaluating venous disease in the future. PMID- 30276360 TI - Recent advances in colorectal cancer screening. PMID- 30276361 TI - Systemic treatment for hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) is one of the most common cancers with high mortality worldwide. Treatment options for patients with advanced stage HCC remain a great challenge.

This review article summarizes systemic treatment options evaluated in HCC focusing on the most recently published data and ongoing studies. PMID- 30276362 TI - Tumor-associated macrophages (TAMs) as biomarkers for gastric cancer: A review. AB - Gastric adenocarcinoma is one of the most common types of cancer worldwide, with an incidence of a million new cases annually. In addition to having a high mortality rate due to often delayed detection and its poor response to cancer therapy, it also spreads aggressively. Inflammation has been shown to play a role in carcinogenesis. Consequently, macrophages are important in phagocytosis, antigen presenting and producing cytokines and growth factors. As a response to microenvironmental signals, they may polarize into tumor resisting M1 or tumor promoting M2 macrophages. Recently, studies have indicated that M2-type macrophage resembling tumor-associated macrophages (TAMs) might be used as an independent prognostic factor for gastric cancer. This review will discuss the possible use of TAMs as prognostic tools for gastric cancer and whether they are suitable for use in clinical environment. PMID- 30276363 TI - Progress in targeted therapy for breast cancer. AB - Breast cancer is a multistep, multifactorial, and heterogeneous disease. Significant transformations have occurred in the systemic management of breast cancer in the past decade. Due to the further understanding of pathogenesis, scientists have found plenty of signaling pathways and correspondingly therapeutic targets in breast cancer, such as hormone receptor, human epidermal growth factor receptor 2 (HER2), epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF), phosphoinositide-3-kinase (PI3K), v akt murine thymoma viral oncogene homolog (AKT), mechanistic target of rapamycin (mTOR), cyclin-dependent kinase 4/6 (CDK4/6), poly (adenosine diphosphate-ribose) polymerase (PARP), and programmed death-1 (PD-1). Targeted therapy, which optimizes the accuracy of antitumor activity and minimizes toxicity to normal tissues, plays a crucial role in breast cancer treatment in the era of precision medicine. In this review, we aimed to summarize the latest developments in targeted therapy for breast cancer and discuss the existing problems. PMID- 30276364 TI - Fine particulate matter (PM2.5): The culprit for chronic lung diseases in China. AB - Air pollution is a world public health problem. Particulate matter (PM), a mix of solid and liquid particles in the air, becomes an increasing concern in the social and economic development of China. For decades, epidemiological studies have confirmed the association between fine particle pollutants and respiratory diseases. It has been reported in different populations that increased Fine particulate matter (PM2.5) concentrations cause elevated susceptibility to respiratory diseases, including acute respiratory distress, asthma, chronic obstructive pulmonary disease, and lung cancer. This review will discuss the pathophysiology of PM2.5 in respiratory diseases, which are helpful for the prevention of air pollution and treatment of respiratory tract inflammatory diseases. PMID- 30276365 TI - Antineutrophil cytoplasmic antibodies-associated glomerulonephritis: From bench to bedside. AB - Antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) is a group of autoimmune disorders that predominantly affects small vessels. The onset of the disease is closely associated with ANCA. Renal involvement, also known as ANCA-associated glomerulonephritis (AGN), is one of the most common manifestations of AAV. In this mini-review, we described the clinical and pathological features of AGN. We then focused on recent studies on the mechanism of acute kidney lesions, including fibrinoid necrosis and crescent formation. Following the basic aspects of kidney injury in AGN, we demonstrated the clinical importance of kidney injury in determining the outcome of patients with AGN. The prognostic value of the 2010 Histopathological Classification of AGN and validating studies were summarized. Finally, treatment and novel therapeutic strategies were introduced addressing the importance of optimizing management of this patient population. PMID- 30276368 TI - Polyethyleneimine methylenecarboxylate: a macromolecular DTPA analogue to chelate plutonium(iv). AB - Up until now, molecular chelating agents, such as diethylenetriamine pentaacetic acid (DTPA), have been the standard method for actinide human decorporation. Mainly active in blood serum, their distribution within the body is thus limited. To treat a wider range of organs affected by plutonium contamination, a potential new class of macromolecular decorporation agents is being studied. Polyethyleneimine methylenecarboxylate (PEI-MC) is one such example. It is being considered here because of its capacity for targeting the liver and bones.

PMID- 30276366 TI - Usefulness of upright T wave in lead aVR for predicting short-term prognosis of patients with ischemic stroke. AB - Background: Upright T wave in lead aVR (TaVR) has recently been reported to be associated with cardiovascular death and mortality in general population and in patients with prior cardiovascular disease (CVD). However, the evidence for the predictive ability of TaVR in patients with ischemic stroke (IS) is lacking. Methods: A total of 625 consecutive patients with IS (mean age: 66 +/- 12 years; 379 male) were enrolled in this study between January 2013 and December 2014. Patients were divided into upright TaVR (>=0 mV; n = 201) and negative TaVR (<0 mV; n = 424) groups. All patients were evaluated with respect to clinical features and in-hospital clinical results. Results: Overall, the prevalence of upright TaVR was 32.2% at baseline. Patients with an upright TaVR were older, had a higher percentage of CVD and hypertension, higher level of MB isoenzyme of creatine kinase (CKMB), faster heart rate, higher rate of QT prolongation > 450 ms, higher rate of negative T in lead II, higher rate of negative T in lead V6, higher rate of ST depression, and longer QTc duration. During the mean follow-up period of 20.0 +/- 5.8 months, 29 (4.6%) patients experienced all-cause death and 12 (1.9%) patients experienced cardiovascular death, the primary end point. Concomitantly, 94 (15%) patients experienced recurrence of IS, the secondary end point. After adjusting for clinical covariates, upright TaVR was independently associated with all-cause death [hazard ratio (HR): 2.88, 95% confidence intervals (CI): 1.07-7.73], cardiovascular death (HR: 3.04, 95% CI: 1.07-8.64), and IS recurrence (HR: 1.86, 95% CI: 1.08-3.20). Conclusions: Upright TaVR in patients with IS is associated with increased mortality and recurrence of IS.

AB - The synthesis of multisubstituted pyrroles by the nickel-catalyzed reaction of N tosyl alkynamides with arylboronic acids is reported. These reactions are triggered by alkyne arylnickelation, followed by cyclization of the resulting alkenylnickel species onto the amide. The reversible E/Z isomerization of the alkenylnickel species is critical for cyclization. This method was applied to the synthesis of pyrroles that are precursors to BODIPY derivatives and a biologically active compound.

AB - Iron-manganese layered double hydroxide nanosheets were developed as an effective photothermal nanocarrier for loading a photosensitizer. The catalase-like activity enables the nanosheets to decompose H2O2 into O2, overcoming tumor hypoxia and enhancing O2-dependent photodynamic therapy (PDT). The combination of PDT and photothermal therapy (PTT) can almost completely eliminate tumor tissues.

AB - Herein, we report a one-step strategy for the electrochemical synthesis of nitrogen doped blue luminescent phosphorene quantum dots (NPQDs) from black phosphorus at room temperature. Nitrogen percentage in NPQDs can be varied by the appropriate choice of solvent and supporting electrolyte. NPQDs [average size 6 +/- 1.5 nm (N = 50)] obtained in this work exhibit ca. 88.7% quantum efficiency. PMID- 30276376 TI - Charge transfer dynamics at the boron subphthalocyanine chloride/C60 interface: non-adiabatic dynamics study with Libra-X. AB - We report a study on the non-adiabatic molecular dynamics (NA-MD) of the charge transfer (CT) process in the boron subphtalocyanine chloride (SubPc)/fullerene (C60) interface using our newly implemented Libra-X software package, which is based on an interface of the Libra NA-MD library and the GAMESS electronic structure software. In particular, we address the following aspects of the simulation protocol: (a) the choice of the potential used to treat interatomic interactions and its effect on the structures of the complex and CT rates; (b) the choice of the electronic structure methodology used; and (c) the choice of the trajectory surface hopping (TSH) methodology used. From our analysis of the electronic structure, we suggest that the distortion of the SubPc conical structure affects orbital localization and that the "breathing" motion of SubPc drives the CT process in SubPc/C60. This study illustrates that the choice of the TSH methodology and electronic decoherence are crucial for the CT simulation. We extend our analysis of CT in SubPc/(C60)n models by increasing the number of C60 molecules up to n = 4. We find that the details of the interfacial SubPc/(C60)n geometry determine the CT rate. Finally, we find the computed CT timescale to be in the range of 2.2-5.0 ps, which is in agreement with the experimentally determined timescale in the order of magnitude of ~10 ps. The developed open source Libra-X package is freely available on the Internet at https://github.com/Quantum-Dynamics-Hub/Libra-X.

AB - A new series of cationic gold(i) pyrazole complexes were prepared in excellent yields as their perchlorate salts. Results of cell viability assays show that these novel complexes have good cytotoxic properties against the human HepG2 cancer cell line. These complexes showed promising anti-cancer activities and to our knowledge, pyrazoles have never been tested against this cell line. The regioselectivity of the complexation is also discussed in regards to the substitution pattern of the pyrazoles.

PMID- 30276380 TI - In vivo measurement of the dynamics of norepinephrine in an olfactory bulb following ischemia-induced olfactory dysfunction and its responses to dexamethasone treatment. AB - Information on the dynamics of molecules following olfactory dysfunction remains essential for understanding the molecular events involved in the pathological process of olfactory dysfunction. This study for the first time demonstrates a method based on the combination of in vivo microdialysis with high performance liquid chromatography (HPLC) and electrochemical detection (ECD) for the measurement of the dynamics of norepinephrine (NE) in the olfactory bulbs of Sprague-Dawley rats following olfactory dysfunction induced by brain ischemia and its responses toward dexamethasone treatment. The method possesses a high spatial resolution and benefits from in vivo microdialysis and high selectivity and is thus capable of measuring NE in the olfactory bulb of rats. With this method, the basal level of NE in the olfactory bulb was evaluated to be ca. 235 +/- 25 nM (n = 6). This level was found to increase by 260 +/- 90% at a time point of 240 min after brain ischemia with bilateral ligation of both common carotid arteries. The increase was found to be suppressed upon the treatment of the animals with 0.2% dexamethasone in the olfactory bulb. These results suggest that NE is involved in the pathological process of ischemia-induced olfactory dysfunction and this information is useful to further understand the molecular events involved in olfactory dysfunction.

AB - A novel 1,4-conjugate addition/esterification of ortho-quinone methides in a multicomponent reaction has been developed. In this protocol, numerous carboxylic acids, ynamides and in situ generated ortho-quinone methides could assemble rapidly to constitute this process for the synthesis of functionalized 3,3 diarylpropanamides with sufficient structural diversity. Furthermore, the products could be transformed to an array of compounds.

AB - A molecular iodine-mediated formal [2+1+1+1] cycloaddition for the efficient synthesis of pyrrolo[2,1-a]isoquinolines from acetophenones, 1,2,3,4 tetrahydroisoquinoline (THIQ) and DMSO has been developed. Mechanistic studies revealed that DMSO served as the methylene source, and this novel protocol involves intermolecular cycloaddition of two in situ generated intermediates that enable efficient formation of one C-N bond and three C-C bonds via multiple sequential C-H functionalizations. PMID- 30276383 TI - The activation of carbon dioxide by first row transition metals (Sc-Zn). AB - The activation of CO2 by chloride-tagged first-row transition metal anions [ClM]- (M = Sc-Zn), was examined by mass spectrometry, quantum chemical calculations, and statistical analysis. The direct formation of [ClM(CO2)]- complexes was demonstrated in the reaction between [ClM]- and neutral CO2. In addition, the reverse reaction was investigated by energy-variable collisionally induced dissociation (CID) of the corresponding [ClM(CO2)]- anions generated in-source. Five different mono- and bi-dentate binding motifs present in the ion/CO2 complexes were identified by quantum chemical calculations and the relative stability of each of these isomers was established and analyzed for all first-row transition metals based on the experimental and theoretical ion/molecule binding energies. It was found that the early first row transition metals form strong covalent bonds with the neutral CO2 molecule, while the late ones and in particular copper and zinc are weakly bonded. Using simple valence bond Lewis diagrams, the different binding motifs and their relative stabilities across the first row were described using multi-configurational self consistent field (MSCSCF) wavefunctions in a quantitative manner based on the electronic structure of the individual metals. This analysis provides an explanation for the change of the most favorite bonding motif of the transition metals with CO2 along the 1st transition metal row. The nature of the activated CO2 complex and the relationship between its stability and other structural and spectral properties was also analyzed by Principal Component Analysis (PCA) and artificial neural networks. PMID- 30276384 TI - HfO2/HfS2 hybrid heterostructure fabricated via controllable chemical conversion of two-dimensional HfS2. AB - While preparing uniform dielectric layers on two-dimensional (2D) materials is a key device architecture requirement to achieve next-generation 2D devices, conventional deposition or transfer approaches have been so far limited by their high cost, fabrication complexity, and especially poor dielectric/2D material interface quality. Here, we demonstrate that HfO2, a high-K dielectric, can be prepared on the top surface of 2D HfS2 through plasma oxidation, which results in a heterostructure composed of a 2D van der Waals semiconductor and its insulating native oxide. A highly uniform dielectric layer with a controlled thickness can be prepared; the possibility of unlimited layer-by-layer oxidation further differentiates our work from previous attempts on other 2D semiconducting materials, which exhibit self-limited oxidation up to only a few layers. High resolution transmission electron microscopy was used to show that the converted HfO2/HfS2 hybrid structure is of high quality with an atomically abrupt, impurity and defect-free interface. Density functional theory calculations show that the unlimited layer-by-layer oxidation occurs because oxygen atoms can barrierlessly penetrate into the HfS2 surface and the extracted sulfur atoms are absorbed into the oxygen vacancy sites within HfO2 under O-rich conditions. A top-gated field effect transistor fabricated with the converted HfO2/HfS2 hybrid structure was found to exhibit a low interface trap density Dit of 6 * 1011 cm-2 eV-1 between the HfS2 channel and the converted HfO2 dielectric, and a high on/off current ratio above 107. Our approach provides a low cost, simple, and ultraclean manufacturing technique for integrating 2D material into device applications. PMID- 30276385 TI - Optimized synthesis and indium complex formation with the bifunctional chelator NODIA-Me. AB - The bifunctional chelator NODIA-Me holds promise for radiopharmaceutical development. NODIA-Me is based on the macrocycle TACN (1,4,7-triazacyclononane) and incorporates two additional methylimidazole arms for metal chelation and an acetic acid residue for bioconjugation. The original two step synthesis was less than optimal due to low yields and the requirement of semi-preparative RP-HPLC purifications. Here, the overall yield for the preparation of NODIA-Me was improved two- to five-fold via two synthetic routes using different protection/deprotection techniques. This way, it was possible (1) to prepare of NODIA-Me on multi-gram scale and (2) to avoid time-consuming HPLC purifications. Inspired by recent results with nat/68Ga3+, preliminary studies on the radiolabeling properties and complex formation of NODIA-Me with nat/111In3+ were performed. Quantitative radiochemical yields were achieved at ambient temperature providing molar activities of ~30 MBq nmol-1, which could be increased to ~240 MBq nmol-1 at 95 degrees C. At r.t., pH 5.5 was optimal for 111In-labeling, but quantitative yields were also achieved in the pH range from 5.5 to 8.2, when the reaction temperature was increased. Stability tests of 111In complexes in vitro revealed high kinetic stabilities in serum and ligand challenge experiments, which is a consequence of the formation of rigid 1 : 1 indium chelates as shown by NMR studies in solution. In summary, the new synthetic routes afford the BFC NODIA-Me in high yields and on large scale. Further, 111In complexation experiments broaden the scope of our chelating system for radiopharmaceutical applications.

AB - Heterogeneous Co(OH)2 nanoplate/Co3O4 nanocube hybrids with rich oxygen vacancies have been constructed through a controllable approach. The high surface areas of such unique nanohybrids together with abundant oxygen vacancies provide more surface active sites, which can facilitate the charge transfer and boost the exchange of intermediates. Specifically, the resultant Co(OH)2 nanoplate/Co3O4 nanocube hybrids display outstanding oxygen evolution reaction (OER) performances with a low overpotential of 281 mV at 10 mA cm-2 and excellent durability after continuous CV of 3000 cycles, shedding light for large-scale applications in practical water splitting.

These interesting scaffolds can be obtained either in a single step from readily available ynamides or in a two-step sequence from the corresponding alkynyl bromide after C-N cross-coupling. This protocol, which only requires a Bronsted or Lewis acid as a promoter, offers an alternative approach toward synthesizing 3-substituted isocoumarins under smooth and fast conditions. PMID- 30276389 TI - N-Rich carbon-coated Co3S4 ultrafine nanocrystals derived from ZIF-67 as an advanced anode for sodium-ion batteries. AB - Transition metal sulfides (TMSs) have been extensively studied as electrode materials for sodium-ion batteries by virtue of their high theoretical capacity. However, the poor cyclability limits the practical application of TMSs in sodium ion batteries. In this study, N-rich carbon-coated Co3S4 ultrafine nanocrystal (Co3S4@NC) was prepared by utilizing ZIF-67 as a precursor through continuous carbonization and sulfuration processes, exhibiting ultrafine nanocrystals with a diameter of about 5 nm. When utilized as the anode for sodium ion batteries, the nanohybrid material exhibits remarkable cycling performance with a high specific capacity of 420.9 mA h g-1 at the current density of 100 mA g-1 after 100 cycles, indicating that the cycling performance is strengthened by the nitrogen-doped carbon coating. Impressively, the obtained material shows good rate performances with reversible specific capacities of 386.7, 284.0, and 151.2 mA h g-1 at 400, 1000, and 1400 mA g-1, respectively, due to the high surface-capacitance contribution and porous structure inherited from the precursor, which finally results in the increase in infiltration of electrolyte and the accelerating diffusion rate of Na+. This study sheds light on the routes to improve the performance of TMSs@nitrogen-doped carbon nanohybrid materials for sodium ion batteries.

AB - Oxidation sites for plasmon-induced charge separation at gold nanocubes and nanorods on TiO2 were visualized by PbO2 deposition, and the sites were localized at plasmonic resonance sites. This indicates that energetic holes generated at those sites dominate the reactions, which can be applied to photo-nanofabrication beyond the diffraction limit. PMID- 30276392 TI - Competition between two cysteines in covalent binding of biliverdin to phytochrome domains. AB - In this work, we disclose a mechanism of competing chemical reactions of protein assembly for a bacterial phytochrome using modern methods of molecular modeling. The recently designed variant of a near-infrared fluorescent protein miRFP670 shows novel and unexpected features of covalent binding of the biliverdin chromophore to cysteine residues in the phytochrome domains GAF and PAS. Upon protein assembly, biliverdin reacts either with a cysteine from GAF, or with two cysteines, one from GAF and one from PAS. We characterize computationally a model structure of the noncovalently bound biliverdin molecule inside the protein cleft of miRFP670 and model reactions of the covalent binding. Both cysteines, Cys20 (PAS) and Cys253 (GAF), are located close to the electrophile C32 atom of biliverdin and can act as nucleophiles. The nucleophilic attack of Cys253 from the GAF domain results in a single C-S bond formation with an activation energy of 16 kcal mol-1. Another pathway, leading to the biliverdin adduct with two C-S bonds, is characterized by lower energy barriers, less than 11 kcal mol-1. Competition between these reaction pathways explains the experimentally obtained mixture of both adducts. On the basis of our first simulations of covalent BV binding to the phytochrome domains, we propose an approach of a direct experimental validation of the reaction mechanisms using IR vibrational spectroscopy. PMID- 30276391 TI - Wulff in a cage gold nanoparticles as contrast agents for computed tomography and photoacoustic imaging. AB - Nanostructures have potential for use in biomedical applications such as sensing, imaging, therapeutics, and drug delivery. Among nanomaterials, gold nanostructures are of considerable interest for biomedical research, owing to their bio-inertness, controllable surface chemistry, X-ray opacity, and optical properties. Gold nanocages are particularly attractive for imaging and therapeutic applications, because they strongly absorb light in the near infra red region which has high light transmission in tissue. However, the X-ray attenuation of nanocages is relatively low due to their hollow structure. In this study, for the first time, we sought to combine the attractive optical properties of nanoshells with the high payloads of solid nanoparticles and investigated their biomedical applications. Here, we report the engineering of Wulff in a cage nanoparticles via converting gold Wulff-shaped seeds into gold-silver core-shell structures and then performing a galvanic replacement reaction. The structure of these nanoparticles was determined using transition electron microscopy. This morphological transformation of gold nanoparticles shaped as truncated octahedrons into a complex Wulff in a cage nanoparticles during the reaction resulted in extensive changes in their optical properties that made these unique structures a potential contrast agent for photoacoustic imaging. We found that the Wulff in a cage nanoparticles had no adverse effects on the viabilities of J774A.1, Renca, and HepG2 cells at any of the concentrations tested. In vitro and in vivo experiments showed robust signals in both photoacoustic imaging and computed tomography. To the best of our knowledge, this is the first report of Wulff in a cage nanoparticles serving as a platform for multiple imaging modalities. This unique multifunctional nanostructure, which integrates the competencies of both core and shell structures, allows their use as contrast agents for photoacoustic imaging, computed tomography and as a potential agent for photothermal therapy.

AB - Conformational mobilities of the units and host-guest complexation with n octyltrimethylammonium hexafluorophosphate of the synthesized perbenzylated pillar[5]arenes were studied. The formed complex was confirmed by proton nuclear magnetic resonance spectroscopy and mass spectral analysis. Hydroxylated pillar[5]arene-based amphiphiles were synthesized by a co-cyclization strategy followed by catalytic hydrogenation. This approach unlocks the synthesis and the design of a wide range of structural manipulations to these amphiphilic pillararenes. PMID- 30276394 TI - Development of a novel optogenetic indicator based on cellular deformations for mapping optogenetic activities. AB - Optogenetic techniques have changed the landscape of neuroscience by offering high temporal and spatial mapping of the activities of genetically defined population of cells with optical controlling tools. The mapping of optogenetic activities demands optogenetic indicators whose optical properties change in response to cellular activities, but the existing optogenetic indicators only specifically characterize limited optogenetic activities. Here, we propose a novel optogenetic indicator based on cellular deformation to characterize the activities of optogenetically engineered cells. The cellular activities triggered by light stimulation lead to changes in the cell membrane structure and result in cellular deformation, which is measured by atomic force microscopy. The deformation recordings of the cells expressing channelrhodopsin-2 (ChR2) and the corresponding control experiments together confirm that the deformation is generated generally when the cells are exposed to light, which is also validated indirectly via the change in the Young's modulus of the cells before and after absorption of photons. The activities of cells expressing different subtypes of opsins were also recorded using the optogenetic indicator of cellular deformation. This study provides a novel and general optogenetic indicator based on cellular deformation for monitoring the activities of optogenetically engineered cells. Moreover, this new optogenetic indicator offers ever-better tools for the applications of optogenetic activity mapping and neural and brain imaging. PMID- 30276395 TI - Metal ion coordination enhancing quantum efficiency of ligand phosphorescence in a double-stranded helical chain coordination polymer of Pb2+ with nicotinic acid. AB - A new 1D phosphorescence coordination polymer (CP) [Pb2O(C6H4NO2)2]n (1; C6H4NO2 = nicotinate) was synthesized by a solvothermal reaction and PbO was used as a Pb(ii) source instead of traditional Pb(ii) salts. This remarkably thermal-stable CP crystallizes in the space group I41/a. In the crystal structure of 1, two different Pb(ii) ions show a five-coordinated and hemidirected coordination geometry, two nonequivalent nicotinate ligands link to Pb(ii) ions in MU2 eta1:eta1 and MU4-eta2:eta2 modes, and the hemidirected coordination polyhedra of Pb(ii) form a helical lead-oxide chain via an edge-sharing fashion along the c axis. Under ambient conditions, 1 emits cyan ligand-based phosphorescence with an absolute quantum yield as high as 59.4% and a lifetime of 9.86 ms under UV-light irradiation. Under the same conditions, nicotinic acid emits simultaneously fluorescence and phosphorescence with a total absolute quantum yield of 4.8%. The great enhancement of phosphorescence quantum yield in 1, regarding nicotinic acid, is assigned to the heavy atom effect of Pb(ii) and negligible pipi interaction between pyridyl rings. Noticeably, the vibronic fine structure is observed in the emission spectrum of 1 at room temperature. Additionally, 1 shows thermochromic behavior, and such functionality probably has realistic application in the field of temperature detection. PMID- 30276396 TI - A loop chain and a three-dimensional network assembled from a multi-dentate nitronyl nitroxide radical and M(hfac)2 (M = CoII, CuII). AB - A multi-dentate nitronyl nitroxide radical Nit-Ph-3,5-bIm (Nit-Ph-3,5-bIm = 2 [3,5-bis(1-imidazole)-phenyl]-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide) reacted with Co(hfac)2.2H2O or Cu(hfac)2 to yield two novel 3d-radical complexes {[Co(hfac)2]2(Nit-Ph-3,5-bIm)}n1 and {[Cu(hfac)2]7(Nit-Ph-3,5-bIm)3}n2 (hfac- = hexafluoroacetylacetonate). In both compounds, the Nit-Ph-3,5-bIm radical ligand behaves as a tetradentate ligand to link four M(hfac)2 units in a MU4 eta1:eta1:eta1:eta1-coordination mode via its two NO groups and two N atoms of imidazole, generating a unique loop chain for 1 and a three-dimensional framework for 2. The magnetic studies revealed a strong antiferromagnetic Co-ON exchange interaction in 1 while a ferromagnetic Cu-ON interaction is observed in 2. The dc magnetic behaviors of two complexes are analyzed by means of appropriate magnetic models. Furthermore, ac magnetic susceptibilities of the Co complex reveal slow relaxation of magnetization.

PMID- 30276398 TI - Self-supported nickel-cobalt nanowires as highly efficient and stable electrocatalysts for overall water splitting. AB - The development and design of highly active and stable electrocatalysts based on cheap and Earth-abundant materials is critically important to enable water splitting as a desirable renewable energy source. Herein, we fulfill the significant electrochemical water splitting enhancement in both electrocatalytic activity and durability by constructing self-supported nickel-cobalt nanowire catalysts with abundant oxygen vacancies. Specifically, the rich oxygen vacancies can largely promote the oxygen evolution reaction (OER) activity of optimal Ni1Co1O2 NWs with a relatively low overpotential of 248 mV to drive a current density of 10 mA cm-2. More significantly, after the phosphorization of Ni1Co1O2 NWs, the resultant Ni1Co1P NWs can also display excellent electrocatalytic hydrogen evolution reaction (HER) performances with an overpotential of only 101 mV to achieve a current density of 10 mA cm-2. Furthermore, benefiting from the unique 1D nanowire structure, the synergistic effect, and the optimal Gibbs free energy for hydrogen evolution evolved from the phosphorization, the Ni1Co1O2 NWs//Ni1Co1P NWs couple is thus highly active and stable for overall water electrolysis with a low voltage of 1.58 V at 10 mA cm-2, showing extraordinary promise for practical overall water splitting electrolysis. PMID- 30276399 TI - Electrically pumped Fabry-Perot microlasers from single Ga-doped ZnO microbelt based heterostructure diodes. AB - Semiconducting micro/nanostructures possessing naturally optical waveguiding behaviors and Fabry-Perot (F-P) like resonances are emerging as versatile building blocks for the assembly of photonic and optoelectronic devices, such as photodetectors, light-emitting diodes, lasers and so on. Individual ZnO micro/nanowires with a rectangular cross-section, such as microwires and microbelts possessing naturally smooth facets along both sides for good optical feedback, can be employed as an underlying F-P mode microcavity whilst as the gain medium for light amplification. In this context, electrically pumped F-P mode microlasers comprising a single ZnO:Ga microbelt and p-GaN substrate have been realized. By treating as the precondition, electrically driven exciton polariton light-emitting behavior was achieved from the heterojunction diodes, which could be ascribed to strong exciton-photon coupling and waveguided nature of the synthesized microbelts. Once the applied bias exceeded the threshold value, an electrically pumped F-P mode lasing behavior could be observed, the lasing peaks centered at 410.5 nm and 450.5 nm respectively, accompanied with a dramatic narrowing of the spectral line-width to be around 1.0 nm emerging on the waveguided emission spectrum. Therefore, the realization of electrically pumped F P mode lasing using single microbelt based heterojunction diodes opens the door not only to the fabrication of coherent light sources and model systems for waveguided resonators, but also affords a competitive candidate to develop electrically pumped and ultralow threshold polariton lasers. PMID- 30276400 TI - Synthesis of heterobimetallic gold(i) ferrocenyl-substituted 1,2,3-triazol-5 ylidene complexes as potential anticancer agents. AB - 1,2,3-Triazol-5-ylidene (trz) complexes of gold(i) containing a ferrocenyl substituent on the C4-position of the trz ring were synthesized to yield the neutral heterobimetallic gold(i) trz chlorido (2), gold(i) trz phenyl (3), and the cationic gold(i) trz triphenylphospine (5) complexes. In order to compare the effect of silver(i) as central metal vs. gold(i), [Ag(trz)2]+ (4) was also prepared, while variation of the C4-1,2,3-triazol-5-ylidene substituent from a ferrocenyl to a phenyl group was done to prepare the monometallic analogue of 5, namely the cationic Au(i) trz triphenylphosphine complex 6. The complexes were characterised with spectroscopic and electrochemical methods, and the single crystal X-ray structures of 2-6 were determined. NMR stability studies of 5 as a representative example of the series of complexes were performed to confirm the stability of the complexes in the solvent dimethylsulfoxide and in aqueous solution. The anti-cancer potential of 5 was evaluated against the lung cancer cell lines A549 and H1975, and the human embryonic kidney cell line (HEK-293) was used as a non-cancer model. IC50 values of 0.89, 0.23 and 5.43 MUM, respectively, were obtained for A549, H1975 and HEK-293, respectively, indicating the activity and selectivity of 5 for cancer cells. Fluorescence microscopy experiments as a preliminary mode-of-action study evidenced an apoptotic cell death mechanism rather than necrotic cell death. PMID- 30276402 TI - Chain-propagation, chain-transfer, and hydride-abstraction by cyclic carbocations on water surfaces. AB - Atmospheric particles contain a wide range of oligomers, but the formation mechanism and the origin of complexity are still unclear. Here, we report the direct detection of carbocationic oligomers generated from the exposure of a series of cyclic unsaturated hydrocarbon gases to acidic water microjets through interface-sensitive mass spectrometry. By changing gas concentrations, H2O (D2O) solvent, bulk pH and comparing results from experiments on acyclic, cyclic, and aromatic compounds, we elucidated three competing reaction mechanisms: chain propagation (CP), chain transfer (CT), and hydride abstraction (HA). We found that conjugative pi-electron delocalization in the carbocation is the most important factor for the interfacial oligomerization processes. Our results showed that electrophilic attack on C[double bond, length as m-dash]C double bonds (CP and CT) is limited, and that on C-H single bonds (HA) is enhanced for carbocations lacking conjugation, which is not the case in bulk organic solutions. Carbocationic oligomers generated by the encounter of gaseous unsaturated hydrocarbons and acidic water surfaces potentially contribute to the molecular complexity in atmospheric particles.

AB - Tumor biomarkers are highly desirable for the screening of patients with a risk of tumor development and progression. Here, we report a beta-galactosidase (beta gal)-responsive acetaminophen (beta-GR-APAP) as a synthetic plasma biomarker for targeted tumor detection. Tumor beta-gal labeling via the recognition of tumor related antigen enabled the detection of a tumor using beta-GR-APAP. PMID- 30276403 TI - Rate exchange rather than relaxation controls structural recovery. AB - We observe structural recovery after an electric field step by probing the dielectric loss profile near its maximum, which displays a field-induced shift towards lower frequencies. These dynamics display time aging-time superposition (TaTS) for the majority of relaxation modes, thus implying homogeneous recovery dynamics. Although assumed by generally accepted models, the same modes can not be responsible for structural relaxation and for structural recovery, as the former is heterogeneous and the latter is homogeneous regarding the nature of the dynamics. This conflict is resolved by proposing that structural recovery is governed by rate exchange, a process that refers to the homogeneous fluctuations of rate constants in equilibrium and restores ergodicity more slowly than the relaxation observed as a simple correlation decay. This recognition has wide ranging consequences on how aging and nonlinear dynamics such as scanning calorimetry should be modeled. PMID- 30276409 TI - Ultra-sensitive microfluidic wearable strain sensor for intraocular pressure monitoring. AB - Wearable technologies have potential to transform healthcare by providing continuous measurements of physiological parameters. Sensors that passively monitor physiological pressure without using electronic components are ideal for wearable contact lenses because they are easy to interface with the cornea and the external environment. Here, we report a passive integrated microfluidic sensor with a novel transduction mechanism that converts small strain changes into a large fluidic volume expansion, detectable by a smart-phone camera. The optimization of the sensor architecture and material properties results in a linear and stable sensor response. We have shown that the sensor has a detection limit of <0.06% for uniaxial and <0.004% for biaxial strain. We embedded our sensor in silicone contact lenses and measured the intraocular pressure induced strain in porcine eyes in the physiological range. The sensor's continuous operation capability for >19 hours and a lifetime reaching >7 months demonstrate its potential for long-term ophthalmic monitoring applications.

AB - CsPbCl3 is a promising material to construct future short wavelength optoelectronic devices based on inorganic perovskite semiconductors. In this study, CsPbCl3 microcrystals were synthesized by a solution phase process. It was found that the photoluminescence (PL) intensities of the CsPbCl3 microcrystals can increase by up to five times under persistent irradiation of UV light without peak shifting, accompanied with an increased absorption coefficient above the band gap and decreased PL lifetime. This PL enhancement is a reversible process with excitation light switching on and off. The photoactivation process of the CsPbCl3 microcrystals is attributed to the passivation of the trap states.

AB - Chiral exocylic vicinal diamines are biologically and chemically important compounds, but they are not easy to make. In this paper, an interesting aminative Umpolung cyclization process has been developed. Aromatic aldehydes 6 bearing an electrophilic chiral sulfinimine group underwent imine formation with 2,2 diphenylglycine (2), decarboxylation, and subsequent Umpolung cyclization, producing various trans-diamines 10 in 84-96% yields with high trans/cis ratios under very mild conditions. This work not only provides an efficient, clean, and mild method for the synthesis of chiral exocyclic vicinal diamines in one step but also represents a new application of aminative Umpolung strategy on intramolecular reactions.

AB - Different from the previous design strategy, herein, a cationic Ir(iii) complex ([(ptbi)2Ir(bisq)]Cl) with a small chlorine as the counterion was synthesized, which realized the formation of a solid film via a vacuum-deposition process. The white OLED, employing it as an orange-emitting layer, achieved excellent performances with a brightness of 50 122 cd m-2, a CE of 25.5 cd A-1, an EQE of 13.1%, accompanied by a low CE efficiency roll-off of 4.7%. These are the best results among evaporated cationic Ir(iii)-based white OLEDs reported so far. PMID- 30276413 TI - Competition between hydrogen bonds and van der Waals forces in intermolecular structure formation of protonated branched-chain alcohol clusters. AB - To investigate the influence of bulky alkyl groups on hydrogen-bonded (H-bonded) network structures of alcohols, infrared (IR) spectra of protonated clusters of 2 propanol (2-PrOH) and tert-butyl alcohol (t-BuOH) were observed in the OH and CH stretch regions. In addition, by varying the tag species, the temperature dependence profile of the isomer population of H+(t-BuOH)n was revealed. An extensive search for stable isomers was performed using dispersion-corrected density functional theory methods, and temperature-dependent IR spectral simulations were done on the basis of the harmonic superposition approximation. The computational results qualitatively agreed with the observed size and temperature dependence of the H-bonded network structures of these protonated bulky alcohol clusters. However, the difficulty in the quantitative evaluation of dispersion was also demonstrated. It was shown that H+(2-PrOH)n (n = 4-7) have essentially the same network structures as the protonated normal alcohol clusters studied so far. On the other hand, H+(t-BuOH)n (n = 4-8) showed a clear preference for the smaller-membered ring structures, that is very different from the preference of the protonated normal alcohol clusters. The origin of the different structure preferences was discussed in terms of the steric effect and dispersion. PMID- 30276414 TI - Dynamic calorimetry and XRD studies of the nematic and twist-bend nematic phase transitions in a series of dimers with increasing spacer length. AB - A modulated and conventional DSC study of the transitions between the twist-bend nematic (Ntb), regular nematic (N) and isotropic liquid (Iso) phases was performed on a series of difluoroterphenyl-based dimers with (CH2)n spacers; n = 5, 7, 9, 11. The enthalpy of Ntb-N transition decreases steeply with increasing n, while that of the N-Iso transition increases with n; hence, the greatest effect of increasing n is a lowering N phase enthalpy. Based on past and present X-ray scattering experiments, we estimate the average molecular conformation in the Ntb phase and perform torsion energy calculations on the spacer. From this, the lowering enthalpy of the N phase is attributed to the decreasing torsional energy cost of bringing the two terphenyls from an inclined twisted conformation in the Ntb phase, to almost parallel in the N phase. With increasing n the C-C bonds of the spacers twist less away from their trans conformation, thereby reducing the overall torsion energy of the N phase. It is speculated that the nearly continuous nature of the Ntb-N transition in n = 11 dimer is associated with the divergence of the helical pitch toward infinity which is intercepted by a final jump at the very weak (0.01 J g-1) first-order transition. Small-angle X ray scattering results suggest similar local cybotactic layering in both nematic phases, with four sublayers, i.e. tails, mesogens, spacers, mesogens.

AB - PURPOSE: Adjusting the antibiotic dose based on an estimation of the glomerular filtration rate (eGFR) may result in subdosing, which may actually be significantly more problematic for intensive care unit (ICU) patients than not adjusting the dose. The aim of this study was to assess the outcomes of antibiotic dose adjustment in ICU patients with renal impairment. METHODS: A retrospective cohort study was conducted in adult patients admitted to an ICU of a Brazilian hospital from January 2014 to December 2015. The eGFR was determined using Cockcroft-Gault and Modified Diet in Renal Disease equations for each day of hospitalization. Treatment failure was defined based on the clinical, laboratory, and radiological criteria. RESULTS: A total of 126 patients were assessed to meet the inclusion criteria and subsequently enrolled in the study (19.9% of patients admitted to the ICU during the study period). Of the 168 opportunities for dose adjustment, 99 (58.9%) adjustments were made. The mean eGFR in the group with dose adjustment was lower than that in the group without dose adjustment (38.5 vs. 40.7 mL/min/1.73 m2, respectively). The treatment failure rate among patients with dose adjustment and those treated with the usual dose was 59.3 and 38.9%, respectively (p = 0.023), and the mortality rates in the respective groups were 74.1 and 55.5% (p = 0.033). An association between dose adjustment and treatment failure/mortality rates was also observed in the multivariate analysis including the prognostic score. CONCLUSIONS: In ICU patients with renal impairment, adjustments in antibiotic dose based on eGFR, significantly increased the risk of treatment failure and death. PMID- 30276418 TI - Ultrasound-guided intermediate cervical plexus and additional peripheral facial nerve block for carotid endarterectomy : A prospective pilot study. AB - BACKGROUND AND OBJECTIVES: Ultrasound-guided intermediate cervical plexus block with perivascular local anesthetic infiltration is an established anesthetic procedure for carotid endarterectomy. In this prospective pilot study an additional subplatysmal block of the superficial ansa cervicalis is presented for the first time. The target structures are the anastomoses between the facial nerve (cervical and marginal mandibular branches) and cervical plexus. METHODS: An ultrasound-guided intermediate cervical plexus block (20 ml of ropivacaine 0.75%) was performed (n = 28). Then, depending on the individual sonoanatomy, 5 ml of prilocaine 1% was injected into the carotid sheath (group 1: no perivascular infiltration, n = 14, group 2: perivascular infiltration, n = 14). The third step was subplatysmal injection of 5 ml of prilocaine 1% between the medial edge of the sternocleidomastoid muscle and the submandibular gland (n = 28). The investigated parameters included the need for supplementation and block related side effects. RESULTS: The requirement for supplemental local anesthetic infiltration in the skin incision area was minimal at mean (M) 1.1 ml (standard deviation (SD) +/-2.4 ml). Perivascular infiltration in group 2 significantly decreased the total amount of local anesthetic supplemented: group 1 M = 4.2 ml (SD = +/-3.1 ml), group 2 M = 1.7 ml (SD = +/-2.0 ml) (p = 0.018). The incidence of block-related side effects was not significantly different between the two groups. CONCLUSION: This study presents an ultrasound-guided subplatysmal block of the superficial ansa cervicalis for the first time, with the aim of optimizing anesthesia quality during surgical interventions in the carotid triangle. PMID- 30276419 TI - Evidence for Gut-Associated Serratia symbiotica in Wild Aphids and Ants Provides New Perspectives on the Evolution of Bacterial Mutualism in Insects. AB - Many insects engage in symbiotic associations with diverse assemblages of bacterial symbionts that can deeply impact on their ecology and evolution. The intraspecific variation of symbionts remains poorly assessed while phenotypic effects and transmission behaviors, which are key processes for the persistence and evolution of symbioses, may differ widely depending on the symbiont strains. Serratia symbiotica is one of the most frequent symbiont species in aphids and a valuable model to assess this intraspecific variation since it includes both facultative and obligate symbiotic strains. Despite evidence that some facultative S. symbiotica strains exhibit a free-living capacity, the presence of these strains in wild aphid populations, as well as in insects with which they maintain regular contact, has never been demonstrated. Here, we examined the prevalence, diversity, and tissue tropism of S. symbiotica in wild aphids and associated ants. We found a high occurrence of S. symbiotica infection in ant populations, especially when having tended infected aphid colonies. We also found that the S. symbiotica diversity includes strains found located within the gut of aphids and ants. In the latter, this tissue tropism was found restricted to the proventriculus. Altogether, these findings highlight the extraordinary diversity and versatility of an insect symbiont and suggest the existence of novel routes for symbiont acquisition in insects. PMID- 30276420 TI - Oral ethinylestradiol-levonorgestrel attenuates cardiac glycogen and triglyceride accumulation in high fructose female rats by suppressing pyruvate dehydrogenase kinase-4. AB - Fructose (FRU) intake has increased dramatically in recent decades with a corresponding increased incidence of insulin resistance (IR), particularly in young adults. The use of oral ethinylestradiol-levonorgestrel (EEL) formulation is also common among young women worldwide. The present study aimed at determining the effect of EEL on high fructose-induced cardiac triglyceride (TG) and glycogen accumulation. The study also investigated the possible involvement of pyruvate dehydrogenase kinase-4 (PDK-4) in EEL and/or high fructose metabolic effects on the heart. Ten-week-old female Wistar rats were allotted into four groups. The control, EEL, FRU, and EEL + FRU rats received distilled water (vehicle, p.o.), 1.0 MUg ethinylestradiol plus 5.0 MUg levonorgestrel (p.o.), 10% fructose (w/v), and 1.0 MUg ethinylestradiol plus 5.0 MUg levonorgestrel and 10% fructose, respectively, daily for 8 weeks. Data showed that EEL or high fructose caused IR' impaired glucose tolerance' hyperlipidemia' increased plasma lactate, lactate dehydrogenase, PDK-4, uric acid, xanthine oxidase (XO), adenosine deaminase (ADA), malondialdehyde (MDA), cardiac uric acid, TG, TG/HDL- cholesterol, glycogen synthesis, MDA, and visceral fat content and reduced glutathione. High fructose also resulted in impaired pancreatic beta-cell function, hyperglycemia, and increased cardiac PDK-4, lactate synthesis, and mass. Nonetheless, these alterations were ameliorated in EEL plus high fructose rats. This study demonstrates that high fructose-induced myocardial TG and glycogen accumulation is attributable to increased PDK-4. Besides, EEL could be a useful pharmacological utility for protection against cardiac dysmetabolism by inhibiting PDK-4. PMID- 30276422 TI - Fatty masses of the abdomen and pelvis and their complications. AB - There are numerous common and rare macroscopic fat-containing masses found in the abdomen and pelvis. These include benign masses, such as lipoleiomyoma, ovarian teratoma, mesenteric teratoma, and lipoma, as well as malignant masses, including liposarcoma and malignant transformation of benign entities. Any mass may become symptomatic due to the development of a complication which may range from ovarian torsion to intussusception to hemorrhage. Imaging plays a vital role in diagnosis and treatment planning when confronted with a symptomatic fat-containing mass. PMID- 30276421 TI - Effects of the second-generation "bath salt" cathinone alpha pyrrolidinopropiophenone (alpha-PPP) on behavior and monoamine neurochemistry in male mice. AB - RATIONALE: Synthetic cathinones ("bath salts") are beta-ketone analogs of amphetamines, yet few studies have examined their potential neurotoxic effects. OBJECTIVE: In the current study, we assessed the persistent behavioral and neurochemical effects of exposure to the second-generation synthetic cathinone alpha-pyrrolidinopropiophenone (alpha-PPP). METHODS: Male, Swiss-Webster mice were exposed to alpha-PPP (80 mg/kg) using a binge-like dosing regimen (QID, q2h). Behavior was assessed 4-5 days after the dosing regimen, and neurochemistry was assessed the following day. Behavior was studied using the elevated plus maze, Y-maze, and novel object recognition tests. Regional levels of dopamine, serotonin, norepinephrine, and the major dopamine metabolite 3,4 dihydroxyphenylacetic acid (DOPAC) were determined in the prefrontal cortex and striatum using high-pressure liquid chromatography. Additional experiments assessed the time courses of the effects of alpha-PPP on locomotor activity and core temperature using telemetry. RESULTS: Exposure to alpha-PPP significantly impaired performance in the Y-maze, decreased overall exploratory activity in the novel object recognition test, and resulted in regionally specific depletions in monoamine neurochemistry. In contrast, it had no significant effect on elevated plus maze performance or object discrimination in the novel object recognition test. The locomotor-stimulant effects of alpha-PPP were comparable to cocaine (30 mg/kg), and alpha-PPP (80 mg/kg) did not induce hyperthermia. CONCLUSIONS: alpha PPP exposure results in persistent changes in exploratory behavior, spatial working memory, and monoamine neurochemistry. This research highlights potential dangers of alpha-PPP, including potential neurotoxicity, and suggests that the mechanisms underlying the persistent untoward effects of the cathinones may be distinct from those of the amphetamines. PMID- 30276423 TI - Heavy metal accumulation in Lathyrus sativus growing in contaminated soils and identification of symbiotic resistant bacteria. AB - In this study, two populations of leguminous plants Lathyrus sativus were grown in four soils that were collected from sites differently contaminated by heavy metals. Evaluations included basic soil properties, concentrations of major nutrients and four metals (copper, zinc, lead and cadmium) in these soils. Investigation of Lathyrus sativus response to contamination showed that the increase of heavy metal concentration in soils affected biomass of plant, number of nodules and plant metal uptake. Heavy metal tolerance of 46 isolated bacteria from the root nodules was evaluated and demonstrated that the maximum concentration of Cd, Pb, Cu and Zn tolerated by strains were 0.8, 2.5, 0.2, and 0.5 mM, respectively. Twenty-two isolates were tested for their effects on plant biomass production and nodule formation and showed that only R. leguminosarum nodulated Lathyrus sativus, while some bacteria improved the shoot and root dry biomass. Sequences of their 16S rDNA gene fragments were also obtained and evaluated for tentative identification of the isolates which revealed different bacterial genera represented by Rhizobium sp, Rhizobium leguminosarum, Sinorhizobium meliloti, Pseudomonas sp, Pseudomonas fluorescens, Luteibacter sp, Variovorax sp, Bacillus simplex and Bacillus megaterium. The existence of Pb- and Cd-resistant genes (PbrA and CadA) in these bacteria was determined by PCR, and it showed high homology with PbrA and CadA genes from other bacteria. The tested resistant population was able to accumulate high concentrations of Pb and Cd in all plant parts and, therefore, can be classified as a strong metal accumulator with suitable potential for phytoremediation of Pb and Cd polluted sites. Heavy metal resistant and efficient bacteria isolated from root nodules were chosen with Lathyrus sativus to form symbiotic associations for eventual bioremediation program, which could be tested to remove pollutants from contaminated sites. PMID- 30276425 TI - Glucocorticoid treatment in juvenile idiopathic arthritis. AB - Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease of joints in childhood. Glucocorticoids are being used in JIA treatment effectively for decades. Although systemic glucocorticoid use decreased with the introduction of biologic drugs, intraarticular glucocorticoid injections (IAGI) with nonsteroidal anti-inflammatory drugs and non-biologic disease modifying anti rheumatic drugs (DMARDs) still remain the primary treatment in JIA, especially in oligoarticular subcategory. Systemic glucocorticoids are used mainly for severe JIA-associated complications such as macrophage activation syndrome (MAS), myocarditis, pericarditis, pleuritis, peritonitis, and severe anemia; as bridging therapy while waiting for the full therapeutic effect of DMARDs; and in certain occasions for patients with severe refractory uveitis. Since glucocorticoid administration is associated with many adverse events, it is important to use glucocorticoids in an optimum way balancing the risks and benefits. The aim of this review is to summarize the current knowledge on glucocorticoid treatment in JIA. A comprehensive literature search was conducted utilizing the Cochrane Library and MEDLINE/PubMed databases. The main topics include mechanism of action, dose, duration, adverse events, vaccination during glucocorticoid treatment, the place of glucocorticoids in JIA treatment guidelines and consensus treatment plans, glucocorticoid use in JIA-associated uveitis, MAS, and IAGI. Data from the literature provide guidance on how to use glucocorticoids in JIA treatment especially for IAGI and systemic use in systemic JIA and MAS. However, there is lack of evidence and need for prospective randomized studies in most parts including the indications in different JIA subcategories, optimum dose/route of administration/duration of treatment, and tapering strategies. PMID- 30276424 TI - Dose-dependent bradycardia as a rare side effect of corticosteroids: a case report and review of the literature. AB - Corticosteroids rank at the first place among the most commonly used immunosuppressive agents in the rheumatology practice. Although their conventional adverse effects including hyperglycemia, hypertension, hyperlipidemia, and osteoporosis are well-recognized and managed, steroid-induced cardiac arrhythmias are known to a lesser extent. In this regard, steroid associated bradycardia is rarely expected and not very well known. Reported cases of steroid-associated bradycardias in the literature predominantly have emerged during the course of intravenous high-dose (pulse) methylprednisolone (MP) administrations. In this paper, we report a patient who developed sinus bradycardia following 52 mg of oral MP administration, improved once the drug was discontinued but repeated with the re-administration. Hence, the patient was shifted to prednisolone (PRED), and again suffered bradycardia which recovered upon dose reduction. Presenting this case along with other similar rare cases in the literature, our aim is to draw attention of fellow rheumatologists, who widely use steroids, to bradycardia-a rare and dose-dependent side effect of steroids. PMID- 30276426 TI - [What is certain in the treatment of rheumatoid arthritis?] AB - Rheumatoid arthritis (RA) is the most important chronic inflammatory joint disease with a prevalence of 1%. When untreated the disease leads to joint destruction and therefore to functional restrictions of the patients and also to increased rates of cardiovascular and malignant diseases. After the pathophysiology of rheumatoid arthritis was better understood, in the last 20 years biologics could be developed, which are directed against targets involved in the inflammatory process in RA. Since then the remission rates of RA have substantially increased. In 2017 Janus kinase (JAK) inhibitors were additionally approved for the treatment of RA in Germany. They further broaden the therapeutic options and, in contrast to biologics, are administered orally. The response rates to therapy are better the earlier the disease is diagnosed and treated. Patients in whom RA is suspected due to a new onset of polyarthritis, should therefore be promptly referred to a rheumatologist. PMID- 30276427 TI - [Influence of primary lymph node status of colorectal cancer on the development of pulmonary metastases and thoracic lymph node metastases]. AB - BACKGROUND: The lungs are the second most common organ site for metastases in patients with colorectal cancer (CRC). Lymph node metastasis of CRC represents a prognostic factor for survival. OBJECTIVE: The present study investigated the influence of CRC lymph node metastasis on lung metastasis, in particular thoracic lymph node metastasis. MATERIAL AND METHODS: A retrospective analysis of 88 patients (n = 56 male) with curative resection of lung metastases of CRC was performed. Primary endpoint: influence of lymph node status of CRC on lung metastases. Secondary endpoints: disease-free survival and overall survival. Statistical evaluation was carried out with SPSS. RESULTS: In 48 patients a positive lymph node status of CRC and in 9 patients an N+ status of lung metastases were determined. The lymph node status of the CRC significantly affected the incidence of synchronous metastases (p = 0.03), disease-free interval until formation of metachronous lung metastases (p = 0.012) and the overall survival of patients with CRC (p = 0.048). The 5-year survival rate for CRC patients with lung metastases was 48.7% after pulmonary metastasectomy. Thoracic lymph node involvement also significantly affected survival (p = 0.001). CONCLUSION: Screening for pulmonary metastases should be included in the staging and follow-up of all patients with CRC, especially in patients with a positive lymph node status of the CRC.

AB - BACKGROUND: Endoscopic vacuum therapy is a widespread method in the postoperative treatment of lower and upper gastrointestinal (GI) tract leakage. OBJECTIVE: There is an absence of further technical development of the standardized material from 2007 for the lower GI tract. MATERIAL AND METHODS: New strategies and new materials for endoscopic vacuum therapy are presented. RESULTS: Alternative strategies in sponge placement, use of open-pore film drainage, use of a multiple sponge system, rinsing catheter, electronic pumps etc. enable the successful treatment of very complex pelvic defects. CONCLUSION: The wide variability of pelvic defects often necessitates a change in therapeutic strategies during the course of treatment for an optimized outcome. PMID- 30276429 TI - [Rabies and Bornavirus encephalitis : Fatal emerging viral encephalitis-a potential problem for organ recipients]. AB - A severe, often fatal encephalitis needs to be extensively and carefully clarified, especially when it occurs in a patient weeks or months after an organ transplantation. If the donor was viremic at the time of the organ removal or living viruses were present in the organ tissue, many viruses can be transferred to the organ recipient. This has been repeatedly reported in recent years and decades. In this overview rabies is discussed as a particularly important form of viral encephalitis, which is transferred via organs and always has a fatal outcome, because patients carry a high risk of infection for all caregivers. Bornavirus has been known in veterinary medicine for many decades and in human medicine has been discussed as possibly being associated with psychiatric diseases. Very recently Bornavirus has been identified as the causative pathogen of fatal encephalitis in organ recipients. The aim of this article is to raise awareness for rabies and Bornavirus disease in intensive care medicine and neurology for organ donors and those taking care of organ recipients. Prevention by knowledge can be lifesaving. PMID- 30276430 TI - [Self-assessment of treatment urgency on presentation to a neurological emergency department : Results of a patient survey]. AB - BACKGROUND: The proportion of patients with neurological disorders as well as the absolute number of patients in German emergency departments is rising. OBJECTIVE: This article presents the results of a survey among patients with self-referral to a dedicated neurological emergency department (ED). We sought to find out if the individual evaluation of urgency for treatment was comparable for patients and physicians. METHODS: During a prospective trial to validate a new and specific neurological triage system over a time period of three months (October 2015 to January 2016), patients who presented themselves to the ED were handed a questionnaire and asked to provide information on the symptoms, including duration and the subjective urgency for evaluation by a physician (priority 1-4, 1 = emergency, 4 = elective). The results were descriptively evaluated and the subjective assessment of urgency was compared to the physicians' evaluation. RESULTS: From a total of 836 questionnaires, handed out to each patient with self referral to the neurological ED, 528 (63%) were returned and analyzed. The most common symptoms were headaches, vertigo, paralysis and sensory deficits. In 24% of the patients the symptoms had lasted less than 24 h, while in 35% the symptoms had persisted for over 1 week. Over half of the patients (55%) indicated that the symptoms needed an emergency evaluation by a physician, while only 3% actually required immediate medical attention according to the retrospective assessment by physicians. This discrepancy was similar even after classification into symptoms and symptom duration. Only 2.6% of the patients stated that the reason for presenting to the ED was the inability to obtain an outpatient appointment. DISCUSSION: Patients regarded their symptoms as being a medical emergency much more often than physicians did. This was independent of the symptoms and their duration. An objective triage for patients in an ED is necessary. PMID- 30276432 TI - [Reduction techniques in intramedullary nailing osteosynthesis]. AB - Intramedullary nailing was originally conceived for the stabilization of shaft fractures of long bones. Due to new nail designs and multiple interlocking possibilities, the spectrum of nailing has significantly increased. Nailing of fractures beyond the isthmus is technically challenging because fractures need to be reduced before the nailing procedure starts. Indirect techniques of reduction include the use of an extension table, a large distractor or an external fixator. Direct reduction with pointed reduction forceps, lag screws, a cerclage wire or a short plate can optimize indirect reduction. The choice of the correct entry portal is of utmost importance for an optimal operative result. The location of the entry portal is dependent on the local anatomy and the bend of the nail. The optimal entry portal at the proximal tibia is directly behind the patellar tendon and accessible with the knee in more than 90 degrees of flexion, alternatively through a suprapatellar approach with a slightly flexed knee joint. Insertion of the nail through the suprapatellar approach is possible without stress on the reduced fracture fragments. Blocking screws create an artificial isthmus in the metaphyseal area and force the guide wire in the desired direction. Blocking screws help to avoid axial malalignment during nail insertion. Interlocking of the nail with screws coming from different directions prevents secondary dislocation. PMID- 30276431 TI - [School-based tobacco prevention: the "Be Smart - Don't Start" program]. AB - The competition for smoke-free classes, the "Be Smart - Don't Start" program has been implemented in Germany since 1997. Using contract management techniques, school classes participating in the competition commit themselves to abstain from smoking for six months. Classes report on a regular basis whether they have stayed smoke-free or not. After the end of the competition period, successful classes participate in a prize draw. The competition aimes to influence social norms.Over the past 20 years, the competition has become a major school-based intervention to prevent smoking in Germany. Several studies addressed process and outcome evaluation, cost-benefit efficacy and iatrogenic effects. Following the evidence so far, the intervention is feasible for implementation in school routines, evokes positive feedback in teachers and students, and reveals a positive cost-benefit ratio. Findings from controlled studies imply that negative side-effects are unlikely to occur and that participation in the competition affects the progression of smoking positively at least in the short term. PMID- 30276433 TI - Functional impairment triggered by altertoxin II (ATXII) in intestinal cells in vitro: cross-talk between cytotoxicity and mechanotransduction. AB - Intestinal cells are able to continuously integrate response to multiple stimuli/stressors; these include the concomitant activation of "chemically driven" pathways, of paramount importance in the response to toxicants, as well as physical stimulation derived from motility. Altertoxin II (ATXII, 0.1, 1 and 10 uM), a mycotoxin produced by the food contaminant fungus Alternaria alternata was studied in HT-29 intestinal adenocarcinoma cells and in non-transformed intestinal epithelial cells, HCEC. One-hour incubation with ATXII was sufficient to trigger irreversible cytotoxicity in both cell types, as well as to modify cellular responses to concomitant pro-oxidant challenge (H2O2, 100-500 uM, DCF-DA assay) suggesting that even relatively short-time exposure of the intestinal cells could be sufficient to alter their functionality. Combination of ATXII (1 uM) with physical stimulation typical of the intestinal compartment (shear stress) revealed differential response of tumor-derived epithelial cells HT-29 in comparison to HCEC, in particular in the localization of the transcription factor Nrf2 (NF-E2-related factor 2). Moreover, ATXII reduced the migratory potential of HCEC as well as their membrane fluidity, but had no respective impact on HT-29 cells. Taken together, ATXII appeared to alter predominantly membrane functionality in HCEC thus hampering crucial functions for cellular motility/turnover, as well as barrier function of healthy intestinal cells and had very limited activity on the tumor counterparts. PMID- 30276434 TI - Excellent 10-year patient-reported outcomes and survival in a single-radius, cruciate-retaining total knee arthroplasty. AB - PURPOSE: Over 2 million Triathlon single-radius total knee arthroplasties (TKAs) have been implanted worldwide. This study reports the 10-year survival and patient-reported outcome of the Triathlon TKA in a single independent centre. METHODS: From 2006 to 2007, 462 consecutive cruciate-retaining Triathlon TKAs were implanted in 426 patients (median age 69 (21-89), 289 (62.5%) female). Patellae were not routinely resurfaced. Patient-reported outcome measures (SF-12, Oxford Knee Scores (OKS), satisfaction) were assessed preoperatively and at 1, 5 and 10 years when radiographs were reviewed. Forgotten Joint Scores (FJS) were collected at 10 years. Kaplan-Meier survival analysis was performed. RESULTS: At 10-11.6 years, 123 patients (128 TKAs) had died and 8 TKAs were lost to follow up. There were four aseptic failures (two cases of tibial loosening, two cases of instability) and four septic failures requiring revision. Symptomatic aseptic radiographic loosening was present in three further cases at 11 years. Four (1%) patellae were secondarily resurfaced. OKS score improved by 17.7 +/- 9.7 points at 1 year (p < 0.001), and was maintained at 34.7 +/- 9.6 at 10 years with FJS 48.5 +/- 31.4. Patient satisfaction was 88% at each timepoint. Ten-year survival was 97.9% (95% confidence interval 96.5-99.3) for revision for any reason, 98.9% (97.7-100) for mechanical failure, and 98.6% (97.4-99.8) for aseptic loosening (symptomatic radiographic or revised). CONCLUSION: The Triathlon TKA continues to show excellent longer-term results with high implant survivorship, low rates of aseptic failure, consistently maintained PROMs and excellent patient satisfaction rates of 88% at 10 years. LEVEL OF EVIDENCE: II, Prospective cohort study. PMID- 30276435 TI - Kinematic alignment in total knee arthroplasty better reproduces normal gait than mechanical alignment. AB - PURPOSE: Kinematic alignment technique for TKA aims to restore the individual knee anatomy and ligament tension, to restore native knee kinematics. The aim of this study was to compare parameters of kinematics during gait (knee flexion extension, adduction-abduction, internal-external tibial rotation and walking speed) of TKA patients operated by either kinematic alignment or mechanical alignment technique with a group of healthy controls. The hypothesis was that the kinematic parameters of kinematically aligned TKAs would more closely resemble that of healthy controls than mechanically aligned TKAs. METHODS: This was a retrospective case-control study. Eighteen kinematically aligned TKAs were matched by gender, age, operating surgeon and prosthesis to 18 mechanically aligned TKAs. Post-operative 3D knee kinematics analysis, performed with an optoelectronic knee assessment device (KneeKG(r)), was compared between mechanical alignment TKA patients, kinematic alignment TKA patients and healthy controls. Radiographic measures and clinical scores were also compared between the two TKA groups. RESULTS: The kinematic alignment group showed no significant knee kinematic differences compared to healthy knees in sagittal plane range of motion, maximum flexion, abduction-adduction curves or knee external tibial rotation. Conversely, the mechanical alignment group displayed several significant knee kinematic differences to the healthy group: less sagittal plane range of motion (49.1 degrees vs. 54.0 degrees , p = 0.020), decreased maximum flexion (52.3 degrees vs. 57.5 degrees , p = 0.002), increased adduction angle (2.0-7.5 degrees vs. - 2.8-3.0 degrees , p < 0.05), and increased external tibial rotation (by a mean of 2.3 +/- 0.7 degrees , p < 0.001). The post operative KOOS score was significantly higher in the kinematic alignment group compared to the mechanical alignment group (74.2 vs. 60.7, p = 0.034). CONCLUSIONS: The knee kinematics of patients with kinematically aligned TKAs more closely resembled that of normal healthy controls than that of patients with mechanically aligned TKAs. This may be the result of a better restoration of the individual's knee anatomy and ligament tension. A return to normal gait parameters post-TKA will lead to improved clinical outcomes and greater patient satisfaction. LEVEL OF EVIDENCE: III. PMID- 30276436 TI - Chronic lateral ankle instability increases the likelihood for surgery in athletes with os trigonum syndrome. AB - PURPOSE: The etiology and incidence of os trigonum syndrome in professional athletes is highly variable. There is a paucity of data to ascertain why some athletes evolve towards surgery whilst others remain asymptomatic. We hypothesized that a lateral ligament ankle injury would increase the likelihood for surgery in those athletes with os trigonum syndrome. METHODS: Eighty professional athletes with clinical and radiological signs of os trigonum syndrome were identified to ascertain the incidence of injury to the lateral ligamentous ankle complex (acute and chronic) by magnetic resonance imaging (MRI). This cohort was subdivided into 2 groups; a surgical (n = 40) and a non surgical (n = 40) cohort. Surgical division was decided if (1) the clinical hyper plantar flexion test was positive, (2) a positive diagnostic ultrasound-guided injection and (3) no improvement was observed after 6 weeks of conservative rehabilitation. RESULTS: From the surgical cohort, 37 players (94.1%) had a chronic lateral ankle ligament injury on MRI, whilst 3 players (5.9%) had an acute lateral ankle ligament injury. Binary logistic linear modelling revealed that having a chronic lateral ligament injury increases the likelihood of os trigonum syndrome surgery by ten times compared to those with an acute lateral ligament injury. CONCLUSION: Professional athletes with chronic lateral ligament ankle injury have an approximate ten times greater risk for os trigonum syndrome surgery compared to athletes with acute lateral ligament ankle injury. LEVEL OF EVIDENCE: IV. PMID- 30276437 TI - High patient satisfaction with significant improvement in knee function and pain relief after mid-term follow-up in patients with isolated patellofemoral inlay arthroplasty. AB - PURPOSE: To prospectively evaluate the clinical and radiographic outcomes and survivorship at 2 and 5 years after isolated contemporary patellofemoral inlay arthroplasty. METHODS: Thirty-four patients were prospectively enrolled in the study and were evaluated preoperatively and at 2 and 5 years postoperatively. Clinical outcomes included the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and the visual analogue scale (VAS) for pain. Kellgren-Lawrence grading was used to assess the progression of tibiofemoral osteoarthritis and the Caton-Deschamps Index to determine patellar height. A Kaplan-Meier survival analysis was used to investigate the implant survivorship. Preoperative patient characteristics were compared among failures and success to determine potential risk factors and patient satisfaction was rated postoperatively. RESULTS: Five of the 34 patients were lost to follow-up resulting in a final follow-up rate of 86%. The total WOMAC subscores of pain and function and the VAS Pain improved significantly at 2- and 5-years, with no significant difference between the two time points. The WOMAC stiffness subscale reached significant improvement at 2-year follow-up alone. No significant progressions of tibiofemoral arthritis or changes in patellar height were observed. A total of six patients (17.1%) failed leaving a survival rate of 91% after 2 years and 83% after 5 years. The main cause for postoperative failure was persistent knee pain; however, no significant preoperative risk factor in patient characteristics could be identified. CONCLUSION: Patellofemoral inlay arthroplasty shows high patient satisfaction with significant improvement in knee function and pain relief after mid-term follow-up with no radiographic progression of tibiofemoral OA.

AB - PURPOSE: Burkitt's lymphoma (BL) is an aggressive lymphoma subtype with high 18F FDG avidity at 18F-FDG-PET/CT, but no validated criteria for PET/CT in treatment evaluation or prediction of outcome in BL are available. The aim of our study was to investigate whether the metabolic baseline PET/CT parameters can predict treatment response and prognosis in BL. MATERIALS AND METHODS: We retrospectively enrolled 65 patients who underwent baseline 18F-FDG-PET/CT, interim and end of treatment PET/CT. The PET images were analyzed visually and semi-quantitatively by measuring the maximum standardized uptake value body weight (SUVbw), the maximum standardized uptake value lean body mass (SUVlbm), the maximum standardized uptake value body surface area (SUVbsa), lesion to liver SUVmax ratio (L-L SUV R), lesion to blood-pool SUVmax ratio (L-BP SUV R), total metabolic tumor volume (tMTV) and total lesion glycolysis (TLG). Survival curves were plotted according to the Kaplan-Meier method. RESULTS: At a median follow-up of 40 months, the median PFS and OS were 34 and 39 months. MTV and TLG were significantly higher in patients with partial response compared to complete response group at end of treatment, while no significant differences were found at interim. Other metabolic PET/CT parameters were not related to treatment response. MTV and TLG were demonstrated to be independent prognostic factors for both PFS and OS; instead SUVbw, SUVlbm, SUVbsa, L-L SUV R and L-BP SUV R were not related to outcome survival. CONCLUSIONS: Metabolic tumour features (MTV and TLG) were significantly correlated with response to treatment and long-term outcome.

PMID- 30276440 TI - Feasibility of multi-parametric PET and MRI for prediction of tumour recurrence in patients with glioblastoma. AB - BACKGROUND: Recurrence in glioblastoma patients often occur close to the original tumour and indicates that the current treatment is inadequate for local tumour control. In this study, we explored the feasibility of using multi-modality imaging at the time of radiotherapy planning. Specifically, we aimed to identify parameters from pre-treatment PET and MRI with potential to predict tumour recurrence. MATERIALS AND METHODS: Sixteen patients were prospectively recruited and treated according to established guidelines. Multi-parametric imaging with 18F-FET PET/CT and 18F-FDG PET/MR including diffusion and dynamic contrast enhanced perfusion MRI were performed before radiotherapy. Correlations between imaging parameters were calculated. Imaging was related to the voxel-wise outcome at the time of tumour recurrence. Within the radiotherapy target, median differences of imaging parameters in recurring and non-recurring voxels were calculated for contrast-enhancing lesion (CEL), non-enhancing lesion (NEL), and normal appearing grey and white matter. Logistic regression models were created to predict the patient-specific probability of recurrence. The most important parameters were identified using standardized model coefficients. RESULTS: Significant median differences between recurring and non-recurring voxels were observed for FDG, FET, fractional anisotropy, mean diffusivity, mean transit time, extra-vascular, extra-cellular blood volume and permeability derived from scans prior to chemo-radiotherapy. Tissue-specific patterns of voxel-wise correlations were observed. The most pronounced correlations were observed for 18F-FDG- and 18F-FET-uptake in CEL and NEL. Voxel-wise modelling of recurrence probability resulted in area under the receiver operating characteristic curve of 0.77 from scans prior to therapy. Overall, FET proved to be the most important parameter for recurrence prediction. CONCLUSION: Multi-parametric imaging before radiotherapy is feasible and significant differences in imaging parameters between recurring and non-recurring voxels were observed. Combining parameters in a logistic regression model enabled patient-specific maps of recurrence probability, where 18F-FET proved to be most important. This strategy could enable risk-adapted radiotherapy planning. PMID- 30276441 TI - Guidelines for Perioperative Care in Esophagectomy: Enhanced Recovery After Surgery (ERAS(r)) Society Recommendations. AB - INTRODUCTION: Enhanced recovery after surgery (ERAS) programs provide a format for multidisciplinary care and has been shown to predictably improve short term outcomes associated with surgical procedures. Esophagectomy has historically been associated with significant levels of morbidity and mortality and as a result routine application and audit of ERAS guidelines specifically designed for esophageal resection has significant potential to improve outcomes associated with this complex procedure. METHODS: A team of international experts in the surgical management of esophageal cancer was assembled and the existing literature was identified and reviewed prior to the production of the guidelines. Well established procedure specific components of ERAS were reviewed and updated with changes relevant to esophagectomy. Procedure specific, operative and technical sections were produced utilizing the best current level of evidence. All sections were rated regarding the level of evidence and overall recommendation according to the evaluation (GRADE) system. RESULTS: Thirty-nine sections were ultimately produced and assessed for quality of evidence and recommendations. Some sections were completely new to ERAS programs due to the fact that esophagectomy is the first guideline with a thoracic component to the procedure. CONCLUSIONS: The current ERAS society guidelines should be reviewed and applied in all centers looking to improve outcomes and quality associated with esophageal resection. PMID- 30276442 TI - Removal of Acidity and Metals from Acid Mine Drainage-Impacted Water using Industrial Byproducts. AB - One of the biggest environmental impacts of mining is the generation of acid mine drainage (AMD). In the absence of proper post-mining management practices, AMD pollution can cause massive environmental damage. Current AMD management practices often fail to meet the expectations of cost, efficiency, and sustainability. The objective of this study was to utilize the metal-binding and acid-neutralizing capacity of an industrial by-product that is otherwise landfilled, namely drinking-water treatment residuals (WTRs), to treat AMD-water, thus offering a green remediation alternative. AMD-water was collected from Tab Simco coal mine in Carbondale, Illinois. It was highly acidic (pH 2.27), and contaminated with metals, metalloids and sulfate at very high concentrations. A filter media, prepared using locally-generated aluminum (Al) and calcium (Ca) based WTRs, was used to increase pH and to remove metals and [Formula: see text] from AMD-water. Laboratory-batch sorption studies at various WTRs (Al and Ca):AMD water ratios were performed to optimize the filter media. WTRs:sand ratio of 1:6 provided optimal permeability, and 1:1 Al-WTRs:Ca-WTRs ratio was the optimal sorbent mix for removal of the metals of concern. A scaled-up study using a 55 gallon WTRs and sand-based filter was designed and tested. The results showed that the filter media removed more than 99% of the initial Fe (137 mg/L), Al (80 mg/L), Zn (11 mg/L), Pb (7 mg/L), As (4 mg/L), Mn (33 mg/L), and 44% of the initial [Formula: see text] (2481 mg/L) from Tab-Simco AMD-water. pH increased from 2.27 to 7.8. Desorption experiments showed that the metals were irreversibly bound to the WTRs and were not released back to the water. PMID- 30276443 TI - Serum miRNA-based distinct clusters define three groups of breast cancer patients with different clinicopathological and immune characteristics. AB - Breast cancer (BCa) is a heterogeneous disease with different histological, prognostic and clinical aspects. Therefore, the need for identification of novel biomarkers for diagnosis, prognosis and monitoring of disease, as well as treatment outcome prediction remains at the forefront of research. The search for circulating elements, obtainable by simple peripheral blood withdrawal, which may serve as possible biomarkers, constitutes still a challenge. In the present study, we have evaluated the expression of 6 circulating miRNAs, (miR-16, miR-21, miR-23alpha, miR-146alpha, miR-155 and miR-181alpha), in operable BCa patients, with non-metastatic, invasive ductal carcinoma, not receiving neoadjuvant chemotherapy. These miRNAs, known to be involved in both tumor cell progression and immune pathways regulation, were analyzed in relation to circulating cytokines, tumor immune-cell infiltration and established prognostic clinicopathological characteristics. We have identified three different clusters, with overall low (C1), moderate (C2) or high (C3) expression levels of these six circulating miRNAs, which define three distinct groups of non-metastatic BCa patients characterized by different clinicopathological and immune-related characteristics, with possibly different clinical outcomes. Our data provide the proof-of-principle to support the notion that, up- or down-regulation of the same circulating miRNA may reflect different prognosis in BCa. Nonetheless, the prognostic and/or predictive potential of these three "signatures" needs to be further evaluated in larger cohorts of BCa patients with an, at least, 5-year clinical follow-up. PMID- 30276444 TI - Female predisposition to TLR7-driven autoimmunity: gene dosage and the escape from X chromosome inactivation. AB - Women develop stronger immune responses than men, with positive effects on the resistance to viral or bacterial infections but magnifying also the susceptibility to autoimmune diseases like systemic lupus erythematosus (SLE). In SLE, the dosage of the endosomal Toll-like receptor 7 (TLR7) is crucial. Murine models have shown that TLR7 overexpression suffices to induce spontaneous lupus like disease. Conversely, suppressing TLR7 in lupus-prone mice abolishes SLE development. TLR7 is encoded by a gene on the X chromosome gene, denoted TLR7 in humans and Tlr7 in the mouse, and expressed in plasmacytoid dendritic cells (pDC), monocytes/macrophages, and B cells. The receptor recognizes single stranded RNA, and its engagement promotes B cell maturation and the production of pro-inflammatory cytokines and antibodies. In female mammals, each cell randomly inactivates one of its two X chromosomes to equalize gene dosage with XY males. However, 15 to 23% of X-linked human genes escape X chromosome inactivation so that both alleles can be expressed simultaneously. It has been hypothesized that biallelic expression of X-linked genes could occur in female immune cells, hence fostering harmful autoreactive and inflammatory responses. We review here the current knowledge of the role of TLR7 in SLE, and recent evidence demonstrating that TLR7 escapes from X chromosome inactivation in pDCs, monocytes, and B lymphocytes from women and Klinefelter syndrome men. Female B cells where TLR7 is thus biallelically expressed display higher TLR7-driven functional responses, connecting the presence of two X chromosomes with the enhanced immunity of women and their increased susceptibility to TLR7-dependent autoimmune syndromes. PMID- 30276445 TI - Sexual dimorphism in HIV-1 infection. AB - Sex-specific differences affecting various aspects of HIV-1 infection have been reported, including differences in susceptibility to infection, course of HIV-1 disease, and establishment of viral reservoirs. Once infected, initial plasma levels of HIV-1 viremia in women are lower compared to men while the rates of progression to AIDS are similar. Factors contributing to these sex differences are poorly understood, and range from anatomical differences and differential expression of sex hormones to differences in immune responses, the microbiome and socio-economic discrepancies, all of which may impact HIV-1 acquisition and disease progression. Ongoing research efforts aiming at controlling HIV-1 disease or reducing viral reservoirs need to take these sex-based differences in HIV-1 pathogenesis into account. In this review, we discuss established knowledge and recent findings on immune pathways leading to sex differences in HIV-1 disease manifestations, with focus on HIV-1 latency and the effect of female sex hormones on HIV-1. PMID- 30276446 TI - Sex-related factors in autoimmune liver diseases. AB - Autoimmune diseases are a broad range of diseases in which the immune system produces an inappropriate response to self-antigens. This results in inflammation, damage, or dysfunction of tissues and/or organs. Many autoimmune diseases are more common in women and differences between female and male immune and autoimmune responses have been well documented. In general, most of the autoimmune diseases seem to affect more females, although there are exceptions. Autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC) are considered to be autoimmune liver diseases (AILD). They all are rare diseases and they result in significant morbidity and mortality. The female predominance in PBC and AIH are among the strongest among autoimmune diseases. However, the mechanisms responsible for the sex differences in autoimmune liver diseases are largely unknown. In this review, we discuss the recent findings on the influence of sex-dependent mechanisms, which may contribute to differences in presentation, clinical characteristics, disease course, and complications observed between female and male patients with autoimmune liver disease. PMID- 30276447 TI - The unhappy triad of the knee re-revisited. AB - AIM OF THE STUDY: To describe the surgical findings of the anterolateral complex in patients with the "unhappy triad" lesion of the knee. METHOD: One hundred and twenty-five consecutive patients presenting with acute anterior cruciate ligament (ACL) tears were selected for this study. Only cases, evaluated with a valgus stress test under fluoroscopy, with a medial opening more than 5 mm of the medial collateral ligament (MCL) were included in the study (11 patients). For the included cases, open MCL surgical repair was performed only in cases with a valgus stress test more than 10 mm as revealed by fluoroscopy (3 patients). All included cases (11 patients) underwent ACL reconstruction and exploration of the anterolateral complex that was then assessed, photographed, classified, and eventually repaired. RESULTS: At clinical evaluation under anaesthesia, all patients presented a positive Lachman test and a pivot shift test graded as ++ in four cases and +++ in five cases, not valuable in two cases. At surgical exploration, the anterolateral complex was involved in all cases (11 patients): one case demonstrated a type I injury, eight cases a type II injury, two cases a type III injury, and no patient with a type IV injury (Segond's fracture). All anterolateral complex lesions were repaired by direct suture and re-tensioning. DISCUSSION: On the basis of a recent analysis performed by other authors, we could speculate that injuries of ACL and anterolateral compartment occur in the very early phase of the injury when the knee is forced into internal rotation. The MRI evidence of bone bruising in the lateral compartment in most cases of the present series support the hypothesis of an internal rotation torque. CONCLUSIONS: The unhappy triad of injuries to the knee is actually a tetrad involving not just the ACL, MCL, and medial/lateral meniscus but also involved the anterolateral complex. PMID- 30276448 TI - Major emergency orthopaedic surgery in patients with a concomitant acute coronary event following trauma. AB - INTRODUCTION: This paper is a short series description of our experience with five cases managed surgically for orthopaedic trauma and who suffered meanwhile an acute coronary event. MATERIALS AND METHODS: Five polytrauma, multiply fractured patients were treated in our institution for various lesions, including an open femur and knee articular fractures, major fractures around the pelvis and hips. They had suffered around the same time an acute coronary event complicating the orthopaedic management. One patient was treated for the orthopaedic condition as a delayed emergency, with a five day retard due to pre-operative pulmonary oedema. Four patients had cardiac evaluation, angiogram or echocardiogram. The patients were managed by a multi-disciplinary team. RESULTS: One patient died post-operatively due to multiple complications, and four patients survived with a good functional outcome. CONCLUSIONS: Patients with acute orthopaedic polytrauma presenting concomitant acute coronary events should be treated by multi disciplinary teams, allowing early surgical management in a safe cardio-vascular and stable haemodynamic status. PMID- 30276449 TI - Long-term survivorship of a monoblock long cementless stem in revision total hip arthroplasty. AB - PURPOSE: The purpose of this study was to assess the clinical outcomes, complications, and survival of a long cementless titanium femoral stem in revision total hip arthroplasty (THA) at a minimum five year follow-up. METHODS: Between 2000 and 2010, 114 patients (116 hips), with a mean age of 68 +/- 12 years, underwent revision THA using a KAR(r) stem (DePuy, Leeds, UK). The main reasons for revision were aseptic loosening (82%), periprosthetic joint infections (PJI) (11%), and periprosthetic fractures (6%). Mean follow-up was ten +/- three years (range, 5-16). Harris Hip Score (HHS), Oxford Hip Score (OHS), and Postel-Merle d'Aubigne (PMA) score were recorded. Radiographic analysis assessed stem osseointegration and subsidence. Survival was analyzed using the Kaplan-Meier (KM) method and cumulative incidence function (CIF). RESULTS: Post operative HHS was 83 +/- 15 (range, 35-99) and OHS was 37 +/- 8 (range, 8-48). PMA score significantly increased from 12 +/- 2 (range, 5-18) pre-operatively to 14.6 +/- 2 (range, 9-18) post-operatively (p = 0.0004). The radiographic Engh score was 15 +/- 8 (range, 7-22). Stem subsidence was observed in two cases (3%). At ten years, five stems had been revised, three for infections and two for periprosthetic fractures. Using the KM method, ten year survival free of stem revision for aseptic loosening was 100%, free of revision for any reason 95%, and free of any re-operation 81%. CONCLUSIONS: The present study reported satisfactory outcomes and survival of a long tapered unlocked cementless femoral stem in revision THA at a minimum follow-up of five years. PMID- 30276450 TI - Patient satisfaction after total knee arthroplasty is better in patients with pre operative complete joint space collapse. AB - AIM OF THE STUDY: To determine if pre-operative radiologic minimal joint space width (mJSW) is related to the outcome of total knee arthroplasty (TKA) (primary hypothesis). Likewise, the aim was to test if pre-operative mJSW is related to prosthesis survival (secondary hypothesis). METHODS: A retrospective comparative analysis was performed. Group 1 was comprised of patients with pre-operative mJSW 0-1 mm. Group 2 were patients with pre-operative mJSW >= 2 mm. The clinical outcome was determined with the Western Ontario and MacMaster Universities Osteoarthritis Index (WOMAC) score pre-operatively and one year after TKA. Only patients with pre-operative weight-bearing radiographs and complete WOMAC score data were accepted. RESULTS: Available for analysis were 377 patients, of whom 188 were allocated to Group 1 (118 female, 70 male, age 70 +/- 11 years) and 189 to Group 2 (118 female, 71 male, age 70 +/- 13 years). Pre-operative WOMAC total and WOMAC subscores showed no significant differences between groups. Post operatively, the WOMAC total was significantly better in Group 1 than in Group 2, 10 +/- 22 and 19 +/- 31, respectively (p < 0.001, Power 97.5%). Similarly, the WOMAC subscores for pain, stiffness, and function were also significantly better in Group 1 than in Group 2. Five-year prosthesis survival was 94.2 and 91.6% in Groups 1 and 2, respectively (p = 0.07, Power 71%). DISCUSSION: Patients with pre operative complete joint space collapse (0 to 1 mm mJSW) achieve a significantly better WOMAC result from TKA than do those with a mJSW equal to or greater than 2 mm. From our findings, it is recommended that "complete joint space collapse" especially be used as an indication for TKA surgery. CONCLUSION: Our study was underpowered to sufficiently show an effect of pre-operative mJSW on prosthesis survival. PMID- 30276453 TI - Lactobacillus supplementation prevents cisplatin-induced cardiotoxicity possibly by inflammation inhibition. AB - PURPOSE: Cardiotoxicity of chemotherapy exerts as the main hurdle for prognosis, while whether cisplatin causes severe cardiotoxicity remains largely unknown. Accumulating evidence reveals that intestinal microbiota functions importantly in nutrient metabolism and cardiovascular function. In this study, we observed the possible cardiotoxicity of cisplatin and explored the possible role of microbiota in the mouse model. METHODS: C57Bl6 mice were treated with 0, 3 or 6 mg/kg cisplatin via i.p. injection, together with or without Lactobacillus supplementation. Cardiac function was analyzed by echocardiography. Gut microbiota was analyzed by 16S RNA sequencing. Gene expression was analyzed by qPCR. The data differences were compared with Graphpad Prism 7.0. RESULTS: In comparison with the control group, 6 mg/kg per week cisplatin treatment for 3 weeks significantly decreased the body weight by about 33% (18.1 +/- 2.1 vs 27.2 +/- 0.9) and decreased the left ventricular ejection fraction by about 15% (0.57 +/- 0.07 vs 0.67 +/- 0.04). Together, the gut microbiota was found dramatically changed, manifested as 27% decrease of Firmicutes and increased pathological bacteria. Antibiotics treatment had no obvious beneficial effects on the body weight and cardiac function caused by cisplatin. However, Lactobacillus supplementation significantly increased the body weight and restored cardiac function, together with lower inflammation gene expression. CONCLUSIONS: The study here has established a possible role of microbiota dysbiosis in cisplatin associated toxic effects, while delivery of Lactobacillus would be beneficial for the cardiac function prevention possibly via inflammation control. PMID- 30276451 TI - A phase II trial of EGFR-TKI readministration with afatinib in advanced non-small cell lung cancer harboring a sensitive non-T790M EGFR mutation: Okayama Lung Cancer Study Group trial 1403. AB - PURPOSE: The aim of this study was to evaluate the efficacy of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) readministration using afatinib in patients with non-small-cell lung cancer (NSCLC) with a sensitive non T790M EGFR mutation who had received cytotoxic chemotherapy after acquiring resistance to EGFR-TKIs. METHODS: Eligible patients had EGFR-mutant tumors resistant to first- or second-generation EGFR-TKIs and an EGFR-TKI-free period with cytotoxic agents. Confirmation of absence of the T790M mutation was required before registration. Afatinib (40 mg/body) was administered daily. The primary endpoint was progression-free survival (PFS). We assumed estimated and threshold PFS times of 3.3 and 1 months, with an alpha of 0.05 and beta of 0.1, respectively. RESULTS: Twelve patients were enrolled from December 2014 to May 2017. The objective response rate and disease control rate were 17% and 84%, respectively. The median PFS time was 4.2 months (95% confidence interval [CI] 2.0-5.8), which met the pre-defined primary endpoint. The median overall survival was 11.6 months (95% CI 9.2-not reached). Grade 3 or worse adverse events included diarrhea (25%), elevated creatinine levels (8%), and hypokalemia (8%), without any treatment-related deaths. CONCLUSION: EGFR-TKI readministration with afatinib for sensitive EGFR-mutant NSCLC without T790M after resistance to a first- or second-generation EGFR-TKI yielded modest activity with tolerable toxicity. It might be one of the treatment options in patients who do not possess T790M tumors, although further studies in this patient setting are warranted. PMID- 30276455 TI - Menstrual Cycle-Related Fluctuations in Breast Volume Measured Using Three Dimensional Imaging: Implications for Volumetric Evaluation in Breast Augmentation. AB - BACKGROUND: Breast volume is a key parameter of breast measurement in breast augmentation. However, the correlation between menstrual cycle phases and variation in breast volume has not been well studied. METHODS: Young female patients with regular menstrual cycles underwent eight three-dimensional imaging scans during a single menstrual cycle from November 2017 to January 2018. Breast volumetric difference at each timepoint and basic breast volume were measured for each subject. Preovulatory phase and postovulatory phase values were compared using an unpaired t test. A Pearson's linear correlated analysis was performed to identify the correlation between the basic breast volume and maximum range of breast volumetric difference during the menstrual cycle. RESULTS: Thirteen patients (26 breasts) met the inclusion criteria. During the menstrual cycle, the breast volumetric difference showed first a rising trend followed by a fall. A significant difference in the breast volumetric difference between the preovulatory phase and postovulatory phase (- 19.6 +/- 2.1 ml pre-ovulation vs. - 6.9 +/- 3.3 ml post-ovulation, p = 0.002) was noted. There was a positive linear association between breast volume and maximum range of breast volumetric difference when a Pearson correlation was used (r = 0.45, p = 0.021). CONCLUSIONS: The breast volume fluctuates during the menstrual cycle, and there is a significant difference between the preovulatory phase and postovulatory phase for breast volumetric change. The influence of the menstrual cycle on breast volume should be taken into consideration by plastic surgeons performing breast augmentation.

PMID- 30276454 TI - Lowering of the High Eyelid Crease in Revision Upper Eyelid Surgery. AB - BACKGROUND: High placement of the lid crease is a common complication in upper eyelid surgery. Correction of the high crease by revision surgery is challenging and has not been well-reported. METHODS: This is a retrospective interventional study of patients who underwent revision eyelid surgery with lowering of the lid crease from 2008 to 2016 at a tertiary institution. Main outcome measures were pretarsal show (PTS) distance, lid crease symmetry, margin reflex distance 1 (MRD1), and lid height symmetry. Lid crease symmetry was graded as symmetrical, mild asymmetry (PTS difference <= 0.5 mm), moderate asymmetry (PTS difference > 0.5 mm but <= 1 mm), or obvious asymmetry (PTS difference > 1 mm). Lid height symmetry was graded as symmetrical, mild asymmetry (MRD1 difference <= 1 mm), moderate asymmetry (MRD1 difference > 1 mm but <= 2 mm), or obvious asymmetry (MRD1 difference > 2 mm). RESULTS: There were a total of 69 patients and 100 eyes. The majority (n = 42, 60.9%) of patients were females. The mean age was 38.3 +/- 17.3 years, and mean follow-up was 16 months. Mean PTS decreased from 3.1 mm pre-surgery to 2.0 mm 2 years post-surgery. The proportion of patients with moderate or severe lid crease asymmetry decreased from 81.1% pre-surgery to 6.7% 2 years post-surgery. The mean MRD1 difference decreased from 1.54 mm pre surgery to 0.23 mm 1 year post-surgery. The proportion of patients with moderate or severe lid height asymmetry improved from 64.5% preoperatively to 4.5% 1 year postoperatively. CONCLUSION: Revision eyelid surgery to correct a high crease is a challenging procedure. We present a technique that is effective in correcting the high lid crease, while simultaneously improving the lid height and lid crease symmetry.

PMID- 30276456 TI - Bacterial Adhesion and Biofilm Formation on Textured Breast Implant Shell Materials. AB - BACKGROUND: Bacterial biofilms have been implicated with breast implant complications including capsular contracture and anaplastic large-cell lymphoma. The actual mechanisms for either are still under active investigation and are not clear. Due to their increased surface area, implants with textured surfaces may harbor greater biofilm loads than those with smooth surfaces. METHODS: Biofilm formation on the outer surface material was compared using implants with various surface areas and roughness, including Natrelle(r) (Smooth), SmoothSilk(r)/SilkSurface(r) (Silk), VelvetSurface (r) (Velvet), Siltex(r), and Biocell(r). The roughness and surface area of each material were assessed using non-contact profilometry. Bacterial attachment (2 h) and biofilm formation (24 h) were evaluated for Staphylococcus epidermidis, Pseudomonas aeruginosa, and Ralstonia pickettii over nine independent experiments using a CDC biofilm reactor and viable plate counts (VPCs) as well as confocal scanning laser microscopy. VPCs of the textured implants were compared relative to the Smooth implant. RESULTS: Surface areas increased with roughness and were similar among the three least rough implants (Smooth, Silk, and Velvet) and among the roughest implants (Siltex and Biocell). Overall, VPC indicated there was significantly more bacterial attachment and biofilm formation on the Siltex and Biocell implants than the Silk or Velvet implants, although there were differences between species and time points. CSLM confirmed the formation of thicker biofilms on the implants with rougher surface textures. CONCLUSION: This in vitro study confirmed that implant surfaces with rougher texture, resulting in more surface area, harbored greater biofilm loads than those with smoother surfaces.

PMID- 30276452 TI - Oncogenic roles of serine-threonine kinase receptor-associated protein (STRAP) in osteosarcoma. AB - PURPOSE: To validate the presence of serine-threonine kinase receptor-associated Protein (STRAP) in osteosarcoma tissue and to investigate the oncological role of STRAP in osteosarcoma. METHODS: Expression of STRAP protein in osteosarcoma tissue compared to soft callus (hyperactive bone healing tissue) and in multiple cell lines was examined using western blot analysis. Effects of STRAP silencing on cell proliferation, invasion, migration and re-implantability in chick chorioallantoic membrane (CAM) were observed in osteosarcoma cell lines (MNNG HOS, 143B, and U2OS). RESULTS: The result demonstrated that STRAP was highly up regulated in osteosarcoma tissues compared with the normal physiological bone healing tissue (soft callus). Expression level of STRAP was markedly high in osteosarcoma cell lines with aggressive phenotype. Upon STRAP silencing, invasion and migration, but not proliferative activity, were selectively modulated in high expression-STRAP cell lines. In addition, STRAP silencing reduced the success rate of tumor implantation and growth of MNNG-HOS cells in CAM model. CONCLUSIONS: Serine-threonine kinase receptor-associated protein is up-regulated during osteosarcoma progression. The presence of STRAP enhances osteosarcoma cell invasion, migration and re-implantation ability, factors which play a critical role in metastasis. Serine-threonine kinase receptor-associated protein and its related pathway are worthy for further exploration as a novel target for anti metastasis agents. PMID- 30276457 TI - Secondary Breast Augmentation: Is There a Trend for Bigger Implants? AB - BACKGROUND: Despite novel assessment tools and 3D simulation, patient's desire for implant size change is one of the most common reasons for revision surgery after primary breast augmentation. In this study, we analysed outcomes and predictive indicators for revision surgeries in a cohort of patients operated on by a single surgeon. PATIENTS AND METHODS: All consecutive patients who underwent revision augmentation surgery between 2013 and 2017 by the first author were included in this study. Besides review of medical records, subgroups based on the indication for revision surgery were compared and statistically analysed. RESULTS: A total of 110 patients were included in this study. Revision surgery was performed 97.2 months on average after primary augmentation. Eighty-six per cent of patients received larger implants. Indications for revision surgery and associated subgroups were: (1) wish for bigger implants (38%), (2) complication + wish for bigger implants (26%), (3) complication (29%), (4) complication + wish for smaller implants (3%) and (5) wish for smaller implants (3%). Subgroup analysis showed that patients who underwent revision surgery for bigger implants were significantly younger compared to patients who suffered a complication or desired smaller implants. Time to secondary augmentation was significantly shorter in case of wish for size change compared to complications as reason for revision surgery. Implant sizes differed significantly in patients where volume change was the sole indication for surgery compared to revisions performed due to complications. CONCLUSION: In our cohort of patients, almost all patients who underwent revision surgery after primary breast augmentation received bigger implants. Patients who specifically wished for size change were younger, asked for surgery earlier and received larger volumes compared to patients who underwent revision surgery for other reasons.

PMID- 30276458 TI - "Dual-Knot Fixation" Technique for Better Stabilization of the Extended Columellar Strut Graft with the Anterior Nasal Spine. AB - INTRODUCTION: Extended columellar strut graft (ecsg.) is one of the most crucial cartilage tissues used especially in secondary rhinoplasties. Stabilization of an ecsg. with the anterior nasal spine (ans.) is very important. Regular suture placement is the most common practice. Nevertheless, this kind of suture fixation may result in sliding of the ecsg. through either side of the ans. Suture placement like the figure of eight may prevent sliding of the ecsg. to sides. However, the figure of eight suture forces the graft to turn around during its fixation. METHOD: I have tried to solve these two problems with a simple still better suture technique. After passing the suture through the hole of the ans., a stabilization knot is tied over the spine tip. Then passing the suture through the lower end of the ecsg. and fixating it with a second knot named as the "fixation knot" results in very good stabilization and prevents both side sliding and rotation of the graft. This stabilization technique can be called "dual-knot fixation" (dkf.). Opening a small notch at the lower tip of the graft may help to hide the "stabilization knot" inside the graft which will help to obscure the tiny space between the cartilage and the bone, and thus the bonding process between the graft and spine would be better.

PMID- 30276459 TI - Simultaneous Nipple-Areola Complex Reconstruction Technique: Combination Nipple Sharing and Tattooing. AB - BACKGROUND: Nipple-areola complex (NAC) reconstruction is the final critical process used to achieve breast symmetry, patient satisfaction, and overall reconstruction completeness. Here, we introduce our simplified simultaneous NAC reconstruction approach with nipple sharing and tattooing that resulted in minimal morbidity, high patient satisfaction, and a shortened total reconstructive period. METHODS: Patients who underwent simultaneous nipple sharing and tattooing between July 2012 and December 2017 after the final operative procedure or adjuvant therapy were included. We retrospectively evaluated breast reconstruction type, interval between breast and NAC reconstruction, mean operation time for simultaneous nipple sharing and tattooing, and postoperative complications. Overall patient satisfaction and willingness to undergo simultaneous NAC reconstruction again were assessed. RESULTS: The mean interval between the final operative procedure or adjuvant therapy and NAC reconstruction was 4.4, 4.4, and 6.7 months in non-adjuvant patients, those who underwent chemotherapy, and those who underwent radiotherapy, respectively. The mean operation time for simultaneous NAC reconstruction was 46 min. No major complications such as infection or total nipple loss were observed regardless of breast reconstruction type at least 6 months postoperatively. The average overall satisfaction was 8.0 on a 10-point scale, and 96.9% of patients indicated that they would undergo this simultaneous NAC reconstruction again. CONCLUSIONS: Our simplified technique of simultaneous nipple sharing and tattooing is safe and reliable and features high patient satisfaction rates. Additionally, it can be performed in the clinical setting and is convenient for patients and surgeons alike since it features a decreased total reconstruction period.

PMID- 30276460 TI - Smooth Muscle Alpha Actin Immunoexpression (alpha-Sma) and CD-117 Antibody (C Kit) in Capsules Formed by Polyurethane Foam-Coated Silicone Implants and with Textured Surface: A Study on Rats. AB - BACKGROUND: One of the undesirable complications that might occur after breast augmentation with silicone implants is capsular contracture. In its etiology, the relations between mast cells and myofibroblasts play an important role in collagen synthesis. Mast cells are able to activate fibroblasts into myofibroblasts, through paracrine secretions, inducing collagen production. The objectives of this study were to analyze the myofibroblast concentration through the alpha-SMA immunomarker and evaluate the intensity of mast cell expression against the C-Kit immunomarker. MATERIAL AND METHOD: Sixty-four Wistar rats were used, divided into two groups (polyurethane foam and textured surface) with 32 animals in each. The animals received silicone implants on the back, below the panniculus carnosus, and after the determined period, they were killed and the capsules formed around the implants were studied. The capsules were analyzed employing the immunohistochemical technique, with the alpha-SMA and C-Kit immunomarkers in subgroups of 30, 50, 70 and 90 days. RESULTS: The myofibroblast concentration was higher in the polyurethane group when compared to the textured group (30 days p = 0.105; 50 days p = 0.247; 70 days p = 0.014 and 90 days p = 0.536). The intensity of mast cell expression was more pronounced in the polyurethane group when compared to the textured group (30 days p = 0.798; 50 days p = 0.537; 70 days p = 0.094 and 90 days p = 0.536). CONCLUSIONS: Polyurethane-coated implants induced higher concentrations of myofibroblasts and higher expression of mast cells, when compared to the textured surface implants.

PMID- 30276461 TI - Within-generation and transgenerational plasticity in growth and regeneration of a subordinate annual grass in a rainfall experiment. AB - Precipitation changes may induce shifts in plant species or life form dominance in ecosystems, making some previously subordinate species abundant. The plasticity of certain plant functional traits of these expanding subordinate species may be one possible mechanism behind their success. In this study, we tested if the subordinate winter annual grass Secale sylvestre shows plasticity in growth and reproduction in response to altered environment associated with field-scale rainfall manipulations (severe drought, moderate drought, and watering) in a semiarid grassland, and whether the maternal environment influences offspring germination or growth in a subsequent pot experiment. Compared to control plots, S. sylvestre plants grew 38% taller, and produced 32% more seeds in severe drought plots, while plants in watered plots were 17% shorter, and had 22% less seeds. Seed mass was greatest in severe drought plots. Plants growing in drought plots had offspring with enhanced juvenile shoot growth compared to the progeny whose mother plants grew in watered plots. These responses are most likely explained by the decreased cover of previously dominant perennial grasses in severe drought plots, which resulted in wetter soil compared to control and watered plots during the peak growth of S. sylvestre. We conclude that the plasticity of this subordinate annual species in response to changing environment may help to gain dominance with recurring droughts that suppress perennial grasses. Our results highlight that exploring both within-generation and transgenerational plasticity of subordinate species may lead to a better prediction of changes in plant species dominance under climate change. PMID- 30276463 TI - Transcriptional repression of CDC6 and SLD2 during meiosis is associated with production of short heterogeneous RNA isoforms. AB - Execution of the meiotic and mitotic cell division programs requires distinct gene expression patterns. Unlike mitotic cells, meiotic cells reduce ploidy by following one round of DNA replication with two rounds of chromosome segregation (meiosis I and meiosis II). However, the mechanisms by which cells prevent DNA replication between meiosis I and meiosis II are not fully understood. Here, we show that transcriptional repression of two essential DNA replication genes, CDC6 and SLD2, is associated with production of shorter meiosis-specific RNAs containing the 3' end of both genes. Despite the short CDC6 RNA coding for a short protein (Cdc6short), this protein is not essential for meiosis and it does not have either a positive or negative impact on DNA replication. Production of CDC6short mRNA does not require the upstream CDC6 promoter (PCDC6) and is not a processed form of the full-length RNA. Instead, CDC6short depends on transcription initiation from within the ORF upon repression of PCDC6. Finally, using CDC6 genes from related yeast, we show that repression of full-length CDC6 mRNA is evolutionarily conserved and that this repression is consistently associated with production of unique short CDC6 RNAs. Together, these data demonstrate that meiotic cells transcriptionally repress full-length CDC6 and SLD2, and that inactivation of PCDC6 results in heterogeneous transcription initiation from within the CDC6 ORF. PMID- 30276464 TI - Gastrointestinal juvenile-like (inflammatory/hyperplastic) mucosal polyps in neurofibromatosis type 1 with no concurrent genetic or clinical evidence of other syndromes. AB - Gastrointestinal "juvenile-like (inflammatory/hyperplastic) mucosal polyps" (JLIHMPs) have been proposed as a neurofibromatosis type 1 (NF1)-specific gastrointestinal manifestation. Juvenile polyposis syndrome (JPS) has also been reported in a NF1 patient, harboring concurrent NF1 and SMAD4 germline mutations. Additionally, NF1-like cafe-au-lait spots have been described in biallelic mismatch repair deficiency, another condition featuring gastrointestinal polyps. The SMAD4 and BMPR1A genes that are involved in 50-60% of JPS cases have not been investigated in the ~ 20 published cases of NF1-associated JLIHMPs with the exception of the abovementioned patient with concomitant JPS and NF1. NF1 defects have been found in the only two cases exhaustively tested. Therefore, JLIHMP has been questioned as an independent, NF1-specific entity. Incidental associations between NF1 and gastrointestinal polyposes at risk for gastrointestinal carcinoma should not be overlooked, given their implications in terms of clinical surveillance. We describe two patients featuring JLIHMPs in clinically/genetically proven NF1, in the absence of SMAD4 and BMPR1A mutations. In one case, the intervening mucosa was markedly inflamed, unlike JPS. We suggest that JLIHMP probably represents a gastrointestinal lesion specific to NF1. PMID- 30276466 TI - Safety and efficacy of preoperative chemotherapy followed by esophagectomy versus upfront surgery for resectable esophageal squamous cell carcinoma. AB - PURPOSE: Neoadjuvant chemotherapy (NAC) followed by esophagectomy has become a standard treatment for esophageal squamous cancer (ESCC) in Japan. We used propensity-matching analysis to clarify the safety and efficacy of NAC in daily clinical practice. METHODS: We reviewed the medical records of 335 patients with clinical Stage II/III ESCC diagnosed between 2007 and 2012, including 191 who received preoperative NAC (NAC group) and 144 treated by upfront surgery (US group). After propensity score matching, there were 118 patients in each group. We compared the postoperative complications and long-term outcomes between the groups. RESULTS: Seven patients in the NAC group underwent replacement therapy. Complications occurred in 76 (68.5%) and 76 (64.4%) patients in NAC and US groups, respectively (p = 0.51), and severe complications occurred in 17 (22.4%) and 30 (39.5%) patients, respectively (p = 0.057). One (0.8%) and three patients (2.5%) from the US group died within 30 days and 90 days after surgery, respectively, but none of the patients from the NAC group died within the same period. The 5-year survival rate was 54.9% in the NAC group and 41.2% in the US group (p = 0.024). CONCLUSIONS: NAC is a safe and effective treatment to improve prognosis in the clinical setting. PMID- 30276467 TI - Treatment results for lumbar epidural lipomatosis: Does fat matter? AB - PURPOSE: The lumbar epidural lipomatosis (LEL) is a rare disease that can cause sciatic pain syndrome or neurological deficits comparable to symptoms caused by a classical spinal canal stenosis. In severe cases surgical decompression was conducted. However, the outcome after decompressive surgery has only been investigated in small case series. In this study we compared the outcome of LEL patients after microsurgery with the outcome of patients with classical spinal stenosis (CSS). METHODS: Patients with LEL (n = 38) and patients with CSS (n = 51), who received microsurgical decompression, were followed in a prospective observational study for 3 years. The clinical results including the Oswestry Disability Index, Numeric Pain Rating Scale (NRS), Roland and Morris Disability Questionnaire, the Short Form-36 Score and the Walking Distance were analysed and compared between both groups. RESULTS: Patients with LEL improved significantly after microsurgical decompression in a 3-year follow-up concerning back pain, leg pain and pain-associated disability equal to patients with CSS (NRSback_LEL_preop. = 6.4; NRSback_CSS_preop. = 6.3; NRSback_LEL_3-years = 3.2; NRSback_CSS_3-years = 3.6; NRSleg_LEL_preop. = 6.3; NRSleg_CSS_preop. = 6.5; NRSleg_LEL_3-years = 2.5; NRSleg_CSS_3-years = 2.9; ODILEL_preop. = 52.7; ODICSS_preop = 51.8; ODILEL_3-years = 32.3; ODICSS_3-years = 27.6). The microsurgical decompression had a positive effect on the health-related quality of life, and patient satisfaction was high in both groups (LEL group-71%, CSS group-69%). CONCLUSIONS: LEL can influence the quality of life dramatically and cause a high degree of disability. A surgical decompression is a safe and effective procedure with a good clinical outcome comparable to the results in patients with an osteoligamentous spinal stenosis. Therefore, microsurgical decompression can be recommended in patients with LEL if conservative treatment fails. These slides can be retrieved under Electronic Supplementary Material. PMID- 30276465 TI - Tau filaments from multiple cases of sporadic and inherited Alzheimer's disease adopt a common fold. AB - The ordered assembly of tau protein into abnormal filaments is a defining characteristic of Alzheimer's disease (AD) and other neurodegenerative disorders. It is not known if the structures of tau filaments vary within, or between, the brains of individuals with AD. We used a combination of electron cryo-microscopy (cryo-EM) and immuno-gold negative-stain electron microscopy (immuno-EM) to determine the structures of paired helical filaments (PHFs) and straight filaments (SFs) from the frontal cortex of 17 cases of AD (15 sporadic and 2 inherited) and 2 cases of atypical AD (posterior cortical atrophy). The high resolution structures of PHFs and SFs from the frontal cortex of 3 cases of AD, 2 sporadic and 1 inherited, were determined by cryo-EM. We also used immuno-EM to study the PHFs and SFs from a number of cortical and subcortical brain regions. PHFs outnumbered SFs in all AD cases. By cryo-EM, PHFs and SFs were made of two C shaped protofilaments with a combined cross-beta/beta-helix structure, as described previously for one case of AD. The higher resolution structures obtained here showed two additional amino acids at each end of the protofilament. The immuno-EM findings, which indicated the presence of repeats 3 and 4, but not of the N-terminal regions of repeats 1 and 2, of tau in the filament cores of all AD cases, were consistent with the cryo-EM results. These findings show that there is no significant variation in tau filament structures between individuals with AD. This knowledge will be crucial for understanding the mechanisms that underlie tau filament formation and for developing novel diagnostics and therapies. PMID- 30276469 TI - Association between delivery of small-for-gestational age neonate and long-term pediatric ophthalmic morbidity. AB - OBJECTIVE: To investigate whether delivery of small for gestational age (SGA) neonate poses a risk for subsequent long-term ophthalmic morbidity. METHODS: In this population-based study, all deliveries between 1991 and 2014 were included. Congenital malformations and multiple gestations were excluded from the analysis. Offspring were defined as either SGA (weight below the 5th percentile for gestational age) or non-SGA. Comparison was performed regarding the incidence of long-term ophthalmic morbidity in a cohort of neonates who were born SGA and those who were not. Ophthalmic morbidity was documented during any encounter with the hospital for a period of up to 18 years after delivery. Ophthalmic morbidity included infections of the eye or the adnexa, inflammation of any cause requiring admission, visual disturbances, and other hospital admissions carrying an ICD-9 code of ophthalmic designation. A Cox proportional hazards model was used to estimate the adjusted hazards ratio (HR) for ophthalmic morbidity During the study period, 243,682 deliveries met the inclusion criteria, of which 11,290 (4.63%) were defined as SGA. RESULTS: During the follow-up period, SGA neonates had higher rates of ophthalmic-related hospitalizations (1.2% versus 1.0%; OR = 1.22, 95% CI 1.02-1.46; p = 0.026). In a Cox proportional hazards model, adjusted for confounders such as maternal age, gestational age at delivery, child birth year, low 5 min Apgar scores (< 7), gestational diabetes, maternal hypertensive disorders, placental abruption and placenta previa, SGA neonate was independently associated with subsequent long-term ophthalmic morbidity (adjusted HR = 1.22; 95% CI 1.02-1.47; p = 0.024). CONCLUSION: Delivery of an SGA neonate is an independent risk factor for long-term ophthalmic morbidity. PMID- 30276468 TI - Assessment of long-term intraocular lens (IOL) decentration and tilt in eyes with pseudoexfoliation syndrome (PES) following cataract surgery. AB - BACKGROUND: To evaluate long-term intraocular lens (IOL) decentration and tilt in eyes with pseudoexfoliation syndrome (PES) following cataract surgery using Visante anterior segment OCT and iTrace Visual Function Analyzer. METHODS: Sixty four eyes following cataract surgery from 2009 to 2012 were included, 34 eyes had PES and 30 eyes did not show PES. A standard phacoemulsification procedure followed by IOL implantation was performed and patients were followed 4-6 years after surgery (mean = 69 months). Best-corrected visual acuity (BCVA), capsulorhexis size, and intraocular pressure (IOP) were measured. IOL decentration and IOL tilt were evaluated using Visante Omni anterior segment OCT (Carl Zeiss Jena GmBH, Germany). The iTrace VFA (Visual Function Analyzer, Hoya surgical optics) was used to measure corneal, internal, and total optical aberrations. RESULTS: Measurements with iTrace showed that horizontal coma was significantly different between PES and control eyes (p = 0.037). Horizontal as well as vertical tilt showed a significant difference between PES and control eyes (p = 0.035 and p = 0.039). Tilt correlated with capsulorhexis size in PES patients (p = 0.011). This indicates a forward tilt of the superior edge of the IOL in eyes with PES. CONCLUSIONS: Patients affected by PES seem to have a higher risk for long-term complications and changes in visual perception due to IOL tilt and decentration after cataract surgery. PMID- 30276470 TI - Spatiotemporal activities of Douglas-fir BiP Pro1 promoter in transgenic potato. AB - MAIN CONCLUSION: The PmBiPPro1 promoter of the luminal binding protein (BiP) from Douglas-fir is fully functional in transgenic potato, responsive to wounding, and has high transcriptional activity in tubers. A predefined pattern and level of transgene expression targeted to specific tissues or organs and at a particular developmental stage is a pre-requisite for the successful development of plants with desired traits. Here, we evaluated the transcriptional activity of the PmBiPPro1 promoter of the luminal binding protein (BiP) from Douglas-fir, by expressing reporter beta-D-glucuronidase (GUS) gene constructs containing three different PmBiPPro1 promoter versions (2258 bp, 1259 bp, and 278 bp) in transgenic potato. In conifers, this promoter regulates the endoplasmic reticulum (ER) molecular chaperon of the HSP70 stress-related protein family and is essential for proper functioning of the ER. Stable expression analysis demonstrated that two of three PmBiPPro1 promoter versions (PmBiPPro1-1 and PmBiPPro1-3) were fully functional in the heterologous host, exhibited high transcriptional activities in the leaves of unstressed potatoes, and were responsive to wounding. Deletion analysis showed that the positive cis-active regulatory elements necessary for higher level expression resided within the - 1243 to - 261 region, whereas negative cis-active elements encompassed nucleotides - 2242 to - 1243. Histochemical staining revealed high level of GUS activities in tissues associated with a high rate of cell division and secretory activities. Most importantly, the PmBiPPro1 promoters, especially the full-length version, had activity in microtubers at a level that was much higher than in any other potato organ or tissue. The - 2242 to - 1243 bp region likely contains important cis element(s) that interact with tuber-specific transcription factors required for promoter activation in the storage organs. The organ-specific activity of the PmBiPPro1 promoters may be useful for targeted expression of heterologous molecules in potato tubers. PMID- 30276471 TI - A review of the seed biology of Paeonia species (Paeoniaceae), with particular reference to dormancy and germination. AB - MAIN CONCLUSION: Most Paeonia species have epicotyl dormancy. Germination of peony seeds requires warm stratification for embryo growth and radicle protrusion followed by cold stratification for epicotyl growth. The genus Paeonia (Paeoniaceae) includes many popular ornamentals, has colorful flowers and contains several Chinese medicinal species. The germination protocol for seeds of Paeonia species is complex and impedes the breeding of new cultivars and contributes to the rarity and high cost of the plants. Although numerous reports on seed dormancy/germination in peonies are scattered throughout the literature, most of them are in Chinese. The primary aims of this paper are to provide a general overview of the available information on seed dormancy/germination in peonies and to make some suggestions regarding propagation for the peony industry and breeders. Most Paeonia species have epicotyl dormancy. The embryo is differentiated into organs, but it is underdeveloped (small) and must grow inside the seed before the radicle can emerge. Germination of peony seeds requires warm stratification for embryo growth and radicle protrusion followed by cold stratification for epicotyl growth. In addition, the epicotyl is sensitive to cold stratification only after the root has grown to a certain length. GA3 treatment enhances embryo growth and subsequent germination percentages. Further investigations on the physiology, genetics and proteomics would contribute to a better understanding of seed dormancy in Paeonia. PMID- 30276472 TI - Occurrence of the black yeast Hortaea werneckii in the Mediterranean Sea. AB - The occurrence of cultivable fungi was investigated along the water column (25 2500 m depth) of four off-shore stations in the Mediterranean basin. An unexpected high abundance of fungi, accompanied by a scarce biodiversity, was observed up to 2500 m depth. The black yeast Hortaea werneckii, known to be one of the most salt tolerant eukaryotic organisms, was isolated for the first time from the Mediterranean Sea, and it was the dominant fungus present in seawater in almost all stations and depths, suggesting its ubiquitous distribution. Isolation of cultivable strains allowed their phylogenetic and taxonomic characterization, and demonstrated that almost all the retrieved fungal species should be considered of terrestrial origin, but well adapted to survive and reproduce at temperature and salinity conditions of the Mediterranean seawater. PMID- 30276473 TI - Emotional talk of patients with breast cancer during review appointments with therapeutic radiographers: effects on fears of cancer recurrence. AB - : Fears of cancer recurrence (FCR) in patients with breast cancer may develop during radiotherapy. Radiographer communication with their patients may influence early survivorship FCR level. AIM: To investigate the management of emotional talk in patients with breast cancer attending their initial review appointments during radiotherapy and predict FCR at 6-8 weeks follow-up. METHODS: A mixed methods observational study was conducted. Patients (consecutive sample, n = 60) with breast cancer, attending a major Scottish cancer centre, had their first two review appointments with their therapeutic radiographer (TR) audio-recorded. In addition, FCR was assessed (FCR7) at baseline and at 6-8 weeks following their final radiotherapy visit. Two TRs participated. Audio files were coded by the VR CoDES system to identify emotional cues and therapeutic radiographer (TR) responses. Linear regression models were tested for fit and to identify factors associated with follow-up FCR, i.e. patient cues, responses by TR. RESULTS: Follow-up FCR was predicted negatively (robust estimator, p = .01) by level of patient emotional talk at the second review session. The provision of space by the TR, at the second session, to enable patients to expand their emotional utterances was also associated, but negatively (p = .01), with follow-up FCR. These effects were maintained after inclusion of covariates: age, treatment received and living conditions. CONCLUSIONS: Patient's emotional expression and TR responses at the second review meeting predicted follow-up FCR. The study shows the effect of communication processes on this specific distress component of the patient's survivorship experience. TRIAL REGISTRATION: NCT02599506. PMID- 30276474 TI - Balneotherapy in chronic inflammatory rheumatic diseases-a narrative review. AB - Since ancient time, thermal baths and mudpacks have been used as treatments for rheumatic diseases and other musculoskeletal complaints. Despite basic researches suggest an anti-inflammatory effect of spa therapy, there is no consensus about the benefits of balneotherapy in patients with chronic inflammatory rheumatic diseases. The aim of this review is to summarize the currently available information on clinical effects of balneotherapy in these diseases. We did a literature search for articles considering the randomized controlled trials (RCTs) published until today. Although many selected studies do not have an elevated methodological quality, data from these RCTs support a beneficial effect of spa therapy. Balneotherapy highly improves the clinical course of the disease in patients with predominant axial involvement, such as with ankylosing and enteropathic spondylitis; the effects are less favorable in patients with predominant peripheral articular inflammation, such as rheumatoid arthritis. Good results have been observed in patients with psoriatic arthritis, but only few RCTs have been conducted on this disease. Spa therapy appears safe, and adverse events have been reported only in a few patients. PMID- 30276475 TI - Impact of climate on the population dynamics of an alpine ungulate: a long-term study of the Tatra chamois Rupicapra rupicapra tatrica. AB - Global warming is considered as a phenomenon having a negative effect on animals living in cold climate. However, herbivorous species inhabiting cold zones may potentially benefit from increase of temperature as this influence duration of vegetation period and increase food resources. In this study, we analyze the impact of climate factors on the long-term dynamics of an isolated and unhunted population of the Tatra chamois Rupicapra rupicapra tatrica. The population growth rate, based on autumnal chamois counting carried out from 1957 to 2016, were correlated with a set of climatic variables. We tested the hypothesis that high temperatures in summer could have a positive impact on the population, since they influence vegetation growth, which ensure food resources. On the other hand, heavy falls of snow and long-lasting and deep snow cover could adversely affect the population by reducing population survival during the winter. The results of this study indicate that climatic variables best explaining the autoregressed population growth rate (from the autumn of year t-1 to the autumn of year t) were the mean summer temperature of year t-1: the population increase was greater following a warmer summer in year t-1 and, in lower extent, the total precipitation during winter: the population decrease was greater following a winter with heavy snowfall. Duration and thickness of snow cover have no negative effect on population growth rate. The results indicate that the population dynamic of the Tatra chamois is determined in the long term by weather conditions, mainly by temperature, when kids are birthing and growing. The results of this work highlight that climatic changes may be responsible for the population dynamic of high-mountain species. Climate warming may lead to increase in duration of vegetation period in cold climatic zones, what may in turn have positive effect on herbivorous species, which relay upon food resources limited by low temperatures within vegetation period. PMID- 30276477 TI - Childhood adversity and sleep are associated with symptom severity in perinatal women presenting for psychiatric care. AB - This study leverages psychiatric intake data from treatment-seeking perinatal women aiming to explore the understudied associations between childhood adversity, sleep quality, and severity of perinatal mental illness in this population. The sample is 578 perinatal women presenting for initial evaluation to a university-based perinatal psychiatry clinic. At intake, we collected demographics, adverse childhood experiences (ACEs), sleep quality, and diagnosis and symptom severity of depression, anxiety, and posttraumatic stress disorder (PTSD). Clinician-rated diagnoses showed that 65% of women met criteria for major depression, 23% for generalized anxiety disorder and 4% for PTSD; almost 30% of women had childhood adversity and 98.2% reported poor perinatal sleep quality. Regression analyses revealed differential associations between ACEs and sleep quality and perinatal mood symptoms; ACEs were significantly associated with pregnancy and postpartum PTSD, whereas sleep quality was associated with perinatal depression and generalized anxiety. Screening for ACEs and sleep quality during perinatal intake has high clinical utility, as these two factors significantly contribute to symptom severity across peripartum. PMID- 30276476 TI - Dietary curcumin supplementation does not alter peripheral blood mononuclear cell responses to exertional heat stress. AB - INTRODUCTION: Curcumin reduces gut barrier damage and plasma cytokine responses to exertional heat stress. However, the role of peripheral blood mononuclear cell (PBMC) in this response remains unclear. PURPOSE: This work investigated the effect of 3 days of 500 mg/day dietary curcumin supplementation on PBMC responses to exertional heat stress in non-heat acclimated humans. METHODS: Eight participants ran (65% VO2max) for 60 min in an environmental chamber (37 degrees C/25% RH) two times (curcumin/placebo). Blood samples were collected pre, post, 1 h post, and 4 h post-exercise. PBMC were isolated from blood samples and the protein content of markers along the TLR4 signaling pathway (TLR4, MyD88, pNF kappaB, NF-kappaB), indicators of cellular energy status (SIRT1 and p-AMPK), and mediators of cellular heat shock response (pHSF-1 and HSP70) were examined with Western blot. Data were analyzed with two-way (condition * time) RM-ANOVAs with Newman-Keuls post hocs. RESULTS: As compared to placebo, curcumin did not alter protein expression in PBMC (p > 0.05). However, in both study conditions at 1 h post-reductions were noted in TLR 4 (- 21.5%; p = 0.03), HSP70 (- 11.0%; p = 0.04), pAMPK (- 48.5%; p < 0.01), and SIRT1 (- 47.8%; p < 0.01). Remarkably, the ratio of pNF-kappaB to NF-kappaB was elevated in both conditions at this same timepoint (+ 75.4%; p = 0.02). CONCLUSIONS: Inflammatory protein expression in PBMC did not differ between curcumin and placebo conditions. Downregulation of pAMPK/SIRT1 and release of HSP70 to the bloodstream may compensate for reduced TLR4, allowing PBMC to maintain inflammatory capacity and preventing an "open window" during the hours following hyperthermic exercise. PMID- 30276478 TI - Long-term vitamin-K antagonist use and coronary artery calcification. AB - BACKGROUND: The aim of this study was to investigate the impact of vitamin K antagonist (VKA) therapy on coronary artery calcification (CAC) by comparing long term VKA users with metallic prosthetic valves (MPVs) and VKA-free patients undergoing coronary calcium scoring for cardiovascular (CV) risk stratification. METHODS: A total of 108 patients (43 VKA users with MPV and 65 gender-, age-, and risk-factor-matched VKA-free patients) were included in the study. CAC was determined via computed tomography (CT) and quantified on the basis of the Agatston score. The VKA group comprised patients who had an MPV for longer than 5 years, which entailed long-term VKA use. RESULTS: Long-term VKA users had more calcified coronary arteries compared with the control group (178.1 +/- 278 vs. 61.1 +/- 130.6, p = 0.01). There was no difference between groups in terms of traditional CV risk factors. The mean duration of VKA use was 15 +/- 7 years for the patients with MPV. There was no correlation between the duration of VKA use and mean Agatston score (r = 0.2, p = 0.215). CONCLUSION: With its unique selection of patient groups, our study extends the findings of previous research that long-term VKA use is related to CAC as detected via CT scanning. The longer and more potent VKA regimen required for MPV patients is the primary cause of CAC in this group. PMID- 30276479 TI - Clinical outcomes after tricuspid surgery : The role of previous cardiac surgery. AB - BACKGROUND: The aim of our study was to assess the outcomes of surgical treatment for severe tricuspid regurgitation according to whether cardiac surgery had been performed before the tricuspid valve intervention. METHODS: Between 1996 and 2013, 201 consecutive patients with severe tricuspid regurgitation underwent tricuspid surgery at our center. Patients were classified according to whether or not they had undergone previous cardiac surgery, which 33% of the sample had. Perioperative as well as long-term morbidity and mortality were analyzed. RESULTS: Mean patient age was 62.3 years. 32.8% underwent suture annuloplasty, 41.3% underwent ring annuloplasty, 15.4% received a bioprosthesis, and 10.4% received a mechanical prosthesis. There were no significant differences in perioperative mortality between the group that had not undergone previous cardiac surgery and the group that had (12.7% vs. 17.9%, respectively; p = 0.32). The long-term mortality rate (median follow-up time: 53 months) was 43.3%. Long-term survival curves showed no significant differences between the two groups (p = 0.884), and previous cardiac surgery was not a predictive factor for long-term mortality (hazard ratio = 1.211; p = 0.521). CONCLUSION: In a series of patients who underwent tricuspid valve surgery, no significant differences were observed in perioperative mortality or in long-term survival according to whether or not subjects had undergone previous cardiac surgery. PMID- 30276480 TI - Head and Neck Cancer: Improving Patient-Reported Outcome Measures for Clinical Practice. AB - OPINION STATEMENT: Head and neck cancer includes a wide range of tumors that occur in several areas of the upper aerodigestive tract. Most head and neck cancer patients report treatment-related late effects (both physical and psycho social). High-quality and patient-centered care in head and neck cancer depend on the understanding of the continuum patient's experience-the disease pathway. Healthcare has been improved by involving patients more actively in the disease process, and a few reports support that patient-reported outcomes-built around the patient's experience-given in a timely manner to oncologists are extremely valuable in oncology clinical care. Implementation and clinical use of patient reported outcomes requires some procedures involving head and neck cancer patients, clinicians, researchers, and institutional leaders The unified and integrated vision is still absent and some current concerns are being discussed to optimize benefits of patient-reported outcomes use in clinical practice. The inclusion of all first-line caregivers, team formation and training, continuous monitoring improvement, and analysis are critical success factors to consider. Our team developed a broader and inclusive understanding of patient-reported outcomes. Patient-reported outcome (Health-Related Quality of Life) assessment is implemented as a systematic and routine process in Head and Neck Unit. Head and neck cancer patients consider the questionnaire administration as part of the clinical approach. We are currently working in a program (PROimp) using mathematical models to identify common head and neck cancer patterns and building prognostic predictive models, to predict future outcomes, to appraise risk/benefit of treatments (standard or new), and to estimate patient's risk of future disease development. It is our aim to better comprehend the singular and unexpected perceptions to really provide directed and personalized cancer care defining the patient pathway.

AB - Anaerobic fungi (phylum Neocallimastigomycota), an early branching family of fungi, are commonly encountered in the digestive tract of mammalian herbivores. To date, isolates from ten described genera have been reported, and several novel taxonomic groupings are detected using culture-independent molecular methods. Anaerobic fungi are recognized as playing key roles in the decomposition of lignocellulose (up to 50% of the ingested and untreated lignocellulose), with their physical penetration and extracellular enzymatical secretion of an unbiased diverse repertoire of cell-wall-degrading enzymes. The secreted cell-wall degrading enzymes of anaerobic fungi include both free enzymes and extracellular multi-enzyme complexes called cellulosomes, both of which have potential as fiber degraders in industries. In addition, anaerobic fungi can provide large amounts of substrates such as hydrogen, formate, and acetate for their co-cultured methanogens. Consequently, large amounts of methane can be produced. And thus, it is promising to use the co-culture of anaerobic fungi and methanogens in the biogas process to intensify the biogas yield owing to the efficient and robust degradation of recalcitrant biomass by anaerobic fungi and improved methane production from co-cultures of anaerobic fungi and methanogens.

AB - Near infrared (NIR) emitting semiconductor quantum dots can be excellent fluorescent nanoprobes, but the poor biodegradability and potential toxicity limits their application. The authors describe a fluorescent system composed of graphene quantum dots (GQDs) as NIR emitters, and novel MnO2 nanoflowers as the fluorescence quenchers. The system is shown to be an activatable and biodegradable fluorescent nanoprobe for the "turn-on" detection of intracellular glutathione (GSH). The MnO2-GQDs nanoprobe is obtained by adsorbing GQDs onto the surface of MnO2 nanoflowers through electrostatic interaction. This results in the quenching of the NIR fluorescence of the GQDs. In the presence of GSH, the MnO2-GQDs nanoprobe is degraded and releases Mn2+ and free GQDs, respectively. This gives rise to increased fluorescence. The nanoprobe displays high sensitivity to GSH and with a 2.8 MUM detection limit. It integrates the advantages of NIR fluorescence and biodegradability, selectivity, biocompatibility and membrane permeability. All this makes it a promising fluorescent nanoprobe for GSH and for cellular imaging of GSH as shown here for the case of MCF-7 cancer cells. Graphical abstract A biodegradable NIR fluorescence nanoprobe (MnO2-GQDs) for the "turn-on" detection of GSH in living cell was established, with the NIR GQD as the fluorescence reporter and the MnO2 nanoflower as the fluorescence quencher. PMID- 30276484 TI - Electrochemical determination of dopamine and uric acid using a glassy carbon electrode modified with a composite consisting of a Co(II)-based metalorganic framework (ZIF-67) and graphene oxide. AB - A composite was prepared from a Co(II)-based zeolitic imidazolate framework (ZIF 67) and graphene oxide (GO) by an in situ growth method. The material was electrodeposited on a glassy carbon electrode (GCE). The modified GCE was used for the simultaneous voltammetric determination of dopamine (DA) and uric acid (UA), typically at working potentials of 0.11 and 0.25 V (vs. SCE). The morphology and structure of the nanocomposite were characterized by scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction. The modified electrode exhibits excellent electroanalytical performance for DA and UA owing to the synergistic effect of the high electrical conductivity of GO and the porosity of ZIF-67. By applying differential pulse voltammetry, a linear response is found for DA in the 0.2 to 80 MUM concentration range, and for UA between 0.8 and 200 MUM, with detection limits of 50 and 100 nM (at S/N = 3), respectively. Further studies were performed on the effect of potential interferents, and on electrode stability and reproducibility. The modified GCE was applied to the simultaneous detection of DA and UA in spiked human urine and gave satisfying recoveries. Graphical abstract Schematic of the preparation procedure of GO-ZIF67 and electrochemical reaction mechanisms of UA and DA at the GO-ZIF67-modified glassy carbon electrode (GCE).

AB - The American lobster, Homarus americanus, is a model for investigating the neuromodulatory control of physiology and behavior. Prior studies have shown that multiple classes of chemicals serve as locally released/circulating neuromodulators/neurotransmitters in this species. Interestingly, while many neuroactive compounds are known from Homarus, little work has focused on identifying/characterizing the enzymes responsible for their biosynthesis, despite the fact that these enzymes are key components for regulating neuromodulation/neurotransmission. Here, an eyestalk ganglia-specific transcriptome was mined for transcripts encoding enzymes involved in neuropeptide, amine, diffusible gas and small molecule transmitter biosynthesis. Using known Drosophila melanogaster proteins as templates, transcripts encoding putative Homarus homologs of peptide precursor processing (signal peptide peptidase, prohormone processing protease and carboxypeptidase) and immature peptide modifying (glutaminyl cyclase, tyrosylprotein sulfotransferase, protein disulfide isomerase, peptidylglycine-alpha-hydroxylating monooxygenase and peptidyl-alpha-hydroxyglycine-alpha-amidating lyase) enzymes were identified in the eyestalk assembly. Similarly, transcripts encoding full complements of the enzymes responsible for dopamine [tryptophan-phenylalanine hydroxylase (TPH), tyrosine hydroxylase and DOPA decarboxylase (DDC)], octopamine (TPH, tyrosine decarboxylase and tyramine beta-hydroxylase), serotonin (TPH or tryptophan hydroxylase and DDC) and histamine (histidine decarboxylase) biosynthesis were identified from the eyestalk ganglia, as were those responsible for the generation of the gases nitric oxide (nitric oxide synthase) and carbon monoxide (heme oxygenase), and the small molecule transmitters acetylcholine (choline acetyltransferase), glutamate (glutaminase) and GABA (glutamic acid decarboxylase). The presence and identity of the transcriptome-derived transcripts were confirmed using RT-PCR. The data presented here provide a foundation for future gene-based studies of neuromodulatory control at the level of neurotransmitter/modulator biosynthesis in Homarus. PMID- 30276487 TI - Association of the CYP4V2 polymorphism rs13146272 with venous thromboembolism in a Chinese population. AB - Genome-wide association studies have identified the CYP4V2 polymorphism (rs13146272) as a risk factor associated with venous thromboembolism (VTE). However, due to the small sample size and variance in genetic analysis models, the relationship between VTE and rs13146272 remains unclear. Here, we performed a case-control study to analyse the associations between rs13146272 and VTE in a Chinese population and to compare the differences among various ethnicities. In this study, 226 VTE patients and 205 healthy controls were recruited, and the allele frequency of variant rs13146272 was analysed by a MassARRAY SNP genotyping assay. In addition, 9 case-control cohorts from 5 studies involving 6667 VTE affected individuals and 8716 control subjects were included in this meta analysis. Pooled ORs and 95% CIs were calculated to assess the association between rs13146272 and VTE by using different genetic models. Our case-control study results showed that there was no significant association between VTE and rs13146272 under the additive model (OR = 0.92, 95% CIs: 0.70-1.21, p = 0.55) in this Chinese population. However, the results of the meta-analysis performed by merging all cohorts showed that rs13146272 was significantly associated with VTE under the additive model, recessive model and dominant model. In the additive and recessive models, the association reached the threshold for genome-wide significance (p < 5.0e-08). In conclusion, our pooled systematic study results indicated that individuals with the A allele had a higher risk of developing VTE than those with the C allele of the rs13146272 variant, but the risk was inconsistent among different ethnicities. Further validation of this association with larger sample sizes and multiple ethnicities is warranted. PMID- 30276485 TI - Metal and metalloid concentrations in soil, surface water, and vegetables and the potential ecological and human health risks in the northeastern area of Hanoi, Vietnam. AB - Heavy metal and metalloid contamination and related risks for the environment and human health are matters of increasing concern. This study assessed metal and metalloid concentrations in soil, surface water, and locally grown vegetable to assess exposure and related risks for the environment and human health in the northeastern rural area of Hanoi. Concentrations of metals and metalloids in soils exceeded regulatory thresholds in some locations (e.g., Me Linh and Gia Lam districts). The carcinogenic elements As and Cr were identified as a major concern with concentrations up to 693 MUg g-1 and 147 MUg g-1, respectively. Industrial point sources or groundwater irrigation practices in the intensive organic farming areas were identified as potential factors contributing to the accumulation of carcinogenic metals and metalloids in topsoil layers. Metal and metalloid concentrations detected in water and vegetables were below the regulatory threshold levels (WHO guideline and maximum allowable limits). While contamination was not observed at a large geographical scale, local soil contamination in specific areas of agricultural importance could pose high ecological and human health-related risks with unclear long-term impacts. The highly carcinogenic soil contamination detected in this study may be a factor adding to the increased cancer incidence rate in Hanoi area, as the total carcinogenic risk calculated for Hanoi area exceeds the cancer likelihood threshold by a factor of 25. Further research is needed to examine potential links, and the involvement of both stakeholders and policy makers is needed to adequately evaluate the risks for Hanoi area and coordinate future remediation plans if risks are justified. PMID- 30276486 TI - Examining the Influence of E-Health Education on Professional Practice. AB - e-Health is steadily integrating into modern health services, making significant changes in the way health services are traditionally delivered. To work in this new environment, healthcare workers are required to have new knowledge, skills and competencies specific to e-Health. The aim of this study was to understand the self-reported perceptions of graduates regarding the influence of an e-Health postgraduate program on their professional careers. In addition, this paper will provide an overview of the e-Health postgraduate program. All graduates from 2005 to 2015 were surveyed using an online questionnaire that consisted of a mixture of closed and open-ended questions. The number of participants in the study was 32. Response rate was 62%. The main motivating factors for studying e-Health were 'relevance to current practice' and 'e-Health is the future'. The participants noted that the opportunity to 'acquiring relevant knowledge' and 'having exposure' were key benefits offered by the e-Health education program. The majority of graduates (n = 23, 72%) thought that the postgraduate e-Health program had an influence on their professional practice. A similar number of participants (n = 23, 72%) mentioned that they had worked in the field of e Health since their graduation. Their professional roles mainly involved 'implementation of e-Health in health service settings' and the 'use of e-Health in clinical practice'. While e-Health may be steadily integrating into modern health services, e-Health specific job opportunities are still relatively limited. e-Health workforce development must be given priority. PMID- 30276488 TI - A multiscale model to predict current absolute risk of femoral fracture in a postmenopausal population. AB - Osteoporotic hip fractures are a major healthcare problem. Fall severity and bone strength are important risk factors of hip fracture. This study aims to obtain a mechanistic explanation for fracture risk in dependence of these risk factors. A novel modelling approach is developed that combines models at different scales to overcome the challenge of a large space-time domain of interest and considers the variability of impact forces between potential falls in a subject. The multiscale model and its component models are verified with respect to numerical approximations made therein, the propagation of measurement uncertainties of model inputs is quantified, and model predictions are validated against experimental and clinical data. The main results are model predicted absolute risk of current fracture (ARF0) that ranged from 1.93 to 81.6% (median 36.1%) for subjects in a retrospective cohort of 98 postmenopausal British women (49 fracture cases and 49 controls); ARF0 was computed up to a precision of 1.92 percentage points (pp) due to numerical approximations made in the model; ARF0 possessed an uncertainty of 4.00 pp due to uncertainties in measuring model inputs; ARF0 classified observed fracture status in the above cohort with AUC = 0.852 (95% CI 0.753-0.918), 77.6% specificity (95% CI 63.4-86.5%) and 81.6% sensitivity (95% CI 68.3-91.1%). These results demonstrate that ARF0 can be computed using the model with sufficient precision to distinguish between subjects and that the novel mechanism of fracture risk determination based on fall dynamics, hip impact and bone strength can be considered validated. PMID- 30276489 TI - Effect of blue LED on the healing process of third-degree skin burns: clinical and histological evaluation. AB - The aim of this study was to evaluate the effects of blue light-emitting diode (LED) on the healing process of third-degree skin burns in rats through clinical and histological parameters. Forty male Wistar rats were divided into two groups: control (CTR) (n = 20) and blue LED (BLUE) (n = 20), with subgroups (n = 5) for each time of euthanasia (7, 14, 21, and 28 days). LED (470 nm, 1 W, 12.5 J/cm2 per point, 28 s) was applied at four points of the wound (total, 50 J/cm2). Feed intake was measured every other day. It was observed that there were no statistically significant differences in the Wound Retention Index (WRI) of the BLUE group in relation to CTR group (p > 0.05) at the evaluation times. After 14, 21, and 28 days, it was observed that the animals in the BLUE group consumed more feed than animals in the CTR group (p < 0.05). At 7 days, there was a statistically significant increase in the angiogenic index (AI) in BLUE (median: 6.2) when compared to CTR (median: 2.4) (p = 0.01) and all animals in BLUE had already started re-epithelialization. This study suggests that blue LED, at the dosimetry used, positively contributed in important and initial stages of the healing process of third-degree skin burns. PMID- 30276490 TI - Q-switched 1064 nm Nd-Yag nanosecond laser effects on skin barrier function and on molecular rejuvenation markers in keratinocyte-fibroblasts interaction. AB - Skin represents an interface between internal and external environment; it protects human body by regulating the water loss and the maintenance of body temperature, defending against irritant and pathogen agents, and against physical, chemical, and UV damage. It provides to essential physiological functions, such as the important antioxidant defense capacity; its protective/defensive function is performed by a high number of proteins, and shows important functions in maintenance of skin barrier homeostasis. Keratinocytes and fibroblasts play a pivotal role to determine or prevent skin aging in response to intrinsic or extrinsic stimuli, modulating cytokines and several biochemical factors. Non-ablative technologies are playing an increasing role in the management of skin aging, inducing a dermal remodeling without a visible epidermal damage. The objective of this study was to evaluate the effect of Q-switched 1064 Nd-YAG laser (Medlite Conbio C6 Nd-YAG laser, Cynosure USA) in skin barrier function, analyzing the constituents which are strongly altered in aging skin. Particularly, we evaluated the expression of filaggrin, TGase, HSP70, and aquaporins, on HaCaT cells. The expression of proinflammatory cytokines has been investigated too.As a second step of the study, we analyzed the modulation of the rejuvenation molecular markers on human skin fibroblasts (HDFs) stimulated with keratinocytes conditioned medium (KCM).Our results demonstrated that Q switched 1064 nm Nd:YAG laser acts on the skin barrier function, increasing the expression of aquaporins, filaggrin, TGase, and HSP70, modulating the proinflammatory cytokines. In fibroblasts stimulated with keratinocytes conditioned medium (KCM) and irradiated with Q-switched 1064 nm Nd:YAG laser, we can observe a reduction of MMP-1 and an increase in procollagen, collagen type I, and elastin. Our results highlight that Q-switched 1064 nm Nd:YAG laser treatment could represent an effective weapon to fight skin aging. PMID- 30276492 TI - Lower Limb Posture Affects the Mechanism of Injury in Under-Body Blast. AB - Over 80% of wounded Service Members sustain at least one extremity injury. The 'deck-slap' foot, a product of the vehicle's floor rising rapidly when attacked by a mine to injure the limb, has been a signature injury in recent conflicts. Given the frequency and severity of these combat-related extremity injuries, they require the greatest utilisation of resources for treatment, and have caused the greatest number of disabled soldiers during recent conflicts. Most research efforts focus on occupants seated with both tibia-to-femur and tibia-to-foot angles set at 90 degrees ; it is unknown whether results obtained from these tests are applicable when alternative seated postures are adopted. To investigate this, lower limbs from anthropometric testing devices (ATDs) and post mortem human subjects (PMHSs) were loaded in three different seated postures using an under-body blast injury simulator. Using metrics that are commonly used for assessing injury, such as the axial force and the revised tibia index, the lower limb of ATDs were found to be insensitive to posture variations while the injuries sustained by the PMHS lower limbs differed in type and severity between postures. This suggests that the mechanism of injury depends on the posture and that this cannot be captured by the current injury criteria. Therefore, great care should be taken when interpreting and extrapolating results, especially in vehicle qualification tests, when postures other than the 90 degrees -90 degrees are of interest. PMID- 30276491 TI - Spectrophotometric determination of platelet counts in platelet-rich plasma. AB - BACKGROUND: Platelet-rich plasma (PRP) is widely used in regenerative dentistry and other medical fields. However, its effectiveness has often been questioned. For better evaluation, the quality of individual PRP preparations should be assured prior to use. We proposed a spectrophotometric method for determination of platelet counts and validated its applicability using two types of PRP preparations. METHODS: Blood samples were obtained from healthy male volunteers and pure PRP (P-PRP) and leukocytes-rich PRP (L-PRP) were prepared using the double-spin method. In serial dilutions, platelet counts in P-PRP and L-PRP were determined using an automated hematology analyzer and a compact spectrophotometer. For validation, P-PRP and L-PRP independently prepared by three well-trained operators were used for comparison of the calculated and measured platelet counts. RESULTS: In the two types of PRP samples evaluated, platelet counts were almost equal and greater amount of both white blood cells (WBCs) and red blood cells (RBCs) were included in L-PRP preparations. The calibration curve obtained from serially diluted P-PRP showed a strong correlation (R2 = 0.995), whereas that of L-PRP was relatively weaker (R2 = 0.975). In validation testing, the scatter plot of the calculated platelet counts versus the measured values showed a strong correlation in P-PRP (R2 = 0.671), whereas that of L-PRP showed a much weaker correlation (R2 = 0.0605). CONCLUSIONS: This method can precisely determine platelet counts in PRP preparations when the inclusion of WBCs or RBCs is minimized. Therefore, we recommend that clinicians use this method for quality assurance of individual PRP preparations. PMID- 30276493 TI - Long Working Hours and Risk of Cardiovascular Disease. AB - PURPOSE OF REVIEW: To summarize the evidence on the relationship between long working hours and cardiovascular disease, such as coronary heart disease and stroke. RECENT FINDINGS: Large-scale meta-analyses with published and individual participant observational data on more than 740,000 men and women free of cardiovascular disease report a link between long working hours (>= 55 h a week) and the onset of cardiovascular events. Our meta-analytic update of summary evidence suggests a 1.12-fold (95% CI 1.03-1.21) increased risk associated with coronary heart disease and a 1.21-fold (95% CI 1.01-1.45) increased risk of stroke, although the evidence is somewhat inconsistent and the possibility of residual confounding and bias cannot be ruled out. Few studies have examined the mechanisms which may be stress-related, behavioral, or biological. The recent pooled analyses suggest that increased cardiac electric instability and hypercoagulability might play a role. The evidence that long working hours are a risk factor for cardiovascular disease is accumulating and suggests a small risk. Studies on the effects of long working hours in high-risk populations and those with pre-existing cardiovascular disease, mechanistic research, and intervention studies are needed to advance this research field. PMID- 30276494 TI - Household Determinants of Liquified Petroleum Gas (LPG) as a Cooking Fuel in SW Cameroon. AB - Currently 70% of the population in Cameroon are reliant on solid fuel for cooking (90% in rural communities) and the associated household air pollution contributes to significant mortality and morbidity in the country. To address the problems of energy security, deforestation and pollution the government has developed a strategy (Masterplan) to increase use of liquified petroleum gas (LPG) as a cooking fuel from 12% to 58% by 2030. As a clean fuel scaled adoption of LPG has the potential to make significant positive impacts on population health. The LPG Adoption in Cameroon Evaluation (LACE) studies are assessing in the community (i) barriers and enablers for and (ii) local interventions to support, adoption and sustained use of LPG. A census survey conducted for LACE in rural and peri-urban regions of SW Cameroon provided an opportunity to investigate current fuel use patterns and factors associated with primary and exclusive use of LPG. A cross sectional survey of 1577 households (1334 peri-urban and 243 rural) was conducted in March 2016 using standardised fuel use and household socio-demographic questions, administered by trained fieldworkers. Wood (40.7%) and LPG (51.1%) were the most frequently reported fuels, although the dominant fuels in rural and peri-urban communities were wood (81%) and LPG (58%) respectively. Fuel stacking was observed for the majority of LPG using households (91% of peri-urban and 99% of rural households). In rural homes, a higher level of education, access to sanitation and piped water and household wealth (income and asset ownership) were all significantly associated with LPG use (p < 0.05). In peri-urban homes, younger age, access to sanitation and piped water and increasing education were significantly associated with both any and exclusive use of LPG (p < 0.05). However, whilst household wealth was related to any LPG use, there was no relationship with exclusive use. Results from this census survey of a relatively well-established LPG market with lower levels of poverty and high levels of education than Cameroon as a whole, find LPG usage well below target levels set by the Cameroon government (58% by 2030). Fuel stacking is an issue for the majority of LPG using households. Whilst, as observed here, education, household wealth and socio-economic status are well recognised predictors of adoption and sustained use of clean modern fuels, it is important to consider factors across the whole LPG eco-system when developing policies to support their scaled expansion. A comprehensive approach is therefore required to ensure implementation of the Cameroon LPG Masterplan achieves its aspirational adoption target within its stated timeframe. PMID- 30276496 TI - Factors related to cervical cancer screening among women of childrearing age: a cross-sectional study of a nationally representative sample in Japan. AB - BACKGROUND: This study aimed to determine the factors related to undergoing cervical cancer screening among Japanese women of childrearing age by focusing on the presence or absence of children. METHODS: This was a cross-sectional study of a nationally representative sample based on the Comprehensive Survey of Living Conditions in Japan. Data for women aged 20-39 were selected, and those whose number of children was unknown, whose youngest child was under 2 years or of unknown age, who were either hospitalized or institutionalized, and who were pregnant were excluded. To determine the factors related to undergoing cervical cancer screening, multivariable logistic regression analysis was performed on the following variables: status of cervical cancer screening, age, number of children, marital status, educational level, cohabitation with parents, employment status, subjective health awareness, hospital use, health check-ups, subjective symptoms of health, and interaction of women's age and number of children. RESULTS: Of the 49,217 women in the analyses, 19,545 (39.7%) underwent cervical cancer screening within the last 2 years. Undergoing cervical cancer screening increased with advancing age. On comparing women with and without children in the same generation, screening rates among women with children were higher than those without children in their early 20s, the same in their late 20s, and lower in their 30s. Receiving health check-ups, higher education, subjective symptoms, and hospital use increased participation in cervical cancer screening. CONCLUSIONS: Although women of childrearing age tended to undergo cervical cancer screening with advancing age, the increase tended to be restrained among mothers. PMID- 30276497 TI - Alcohol quantity and quality price elasticities: quantile regression estimates. AB - Many people drink more than the recommended level of alcohol, with some drinking substantially more. There is evidence that suggests that this leads to large health and social costs, and price is often proposed as a tool for reducing consumption. This paper uses quantile regression methods to estimate the differential price (and income) elasticities across the drinking distribution. This is also done for on-premise (pubs, bars and clubs) and off-premise (supermarkets and shops) alcohol separately. In addition, we examine the extent to which drinkers respond to price changes by varying the 'quality' of the alcohol that they consume. We find that heavy drinkers are much less responsive to price in terms of quantity, but that they are more likely to substitute with cheaper products when the price of alcohol increases. The implication is that price-based policies may have little effect in reducing consumption amongst the heaviest drinkers, provided they can switch to lower quality alternatives. PMID- 30276495 TI - Role of Percutaneous Chronic Total Occlusion Interventions in Patients with Ischemic Cardiomyopathy and Reduced Left Ventricular Ejection Fraction. AB - PURPOSE OF REVIEW: The purpose of this review is to examine current evidence on the benefit of chronic total occlusion (CTO) revascularization in patients with ischemic cardiomyopathy and propose a systematic approach on how and when to accomplish revascularization in these patients. RECENT FINDINGS: Coronary revascularization in patients with reduced ejection fraction (EF) is advocated for to improve left ventricular function and consequently clinical outcomes. Approximately 16-31% of angiograms in patients with advanced CAD are noted to have a concomitant coronary CTO. Its presence is a main predictor of worse outcomes. Over the past 15 years, advancements in interventional technologies and techniques have made it possible to treat CTO lesions percutaneously with success rates exceeding 90%. Different revascularization techniques have been organized into widely used algorithms for systematic CTO lesion crossing and treatment. Patients with reduced EF can be revascularized percutaneously with goal of complete functional revascularization. However, randomized prospective data is needed to justify the increased patient risks and healthcare costs associated with these procedures. PMID- 30276498 TI - Brain metabolism and related connectivity in patients with acrophobia treated by virtual reality therapy: an 18F-FDG PET pilot study sensitized by virtual exposure. AB - BACKGROUND: The aim of this pilot study is to investigate the impact of virtual reality exposure therapy (VRET) on brain metabolism and connectivity. Eighteen patients with acrophobia were assessed by an 18F-FDG PET scan sensitized by virtual exposure before treatment, and nine of them were assessed again after eight sessions of VRET. Statistical Parametric Mapping was used to study the correlations between metabolism and pretherapeutic clinical scores and to compare metabolism before and after VRET (p voxel < 0.005, corrected for cluster volume). Metabolic connectivity was evaluated through interregional correlation analysis. RESULTS: Before therapy, a positive correlation was found between scores on the behavioural avoidance test and left occipital metabolism (BA17-18). After VRET, patients presented increased metabolism in the left frontal superior gyri and the left precentral gyrus, which showed increased metabolic connectivity with bilateral occipital areas (BA17-18-19), concomitant with clinical recovery. CONCLUSIONS: This study highlights the exciting opportunity to use brain PET imaging to investigate metabolism during virtual exposure and reports the involvement of the visual-motor control system in the treatment of acrophobia by VRET. PMID- 30276499 TI - Microbial community dynamics in an ANAMMOX reactor for piggery wastewater treatment with startup, raising nitrogen load, and stable performance. AB - Bacterial community dynamics of the ANAMMOX reactor of an integrated "UASB + SHARON + ANAMMOX" system for treating piggery wastewater were investigated using the Illumina MiSeq method with samples obtained at ~ 2-week intervals during a 314-day period. With aerobic activated sludge as seeds and low content artificial wastewater (NH4+-N 50 mg/L; NO2--N 55 mg/L) as influent for the ANAMMOX reactor, nitrogen removal was initially observed on day 38 with a removal rate 1.3 mg N L 1 day-1, and increased to 90.4 mg N L-1 day-1 on day 55 with almost complete removal of ammonia and nitrite, indicating a successful startup of the reactor. Increasing influent load stepwise to NH4+-N 272.7 mg/L/NO2--N 300 mg/L, nitrogen removal rate increased gradually to 470 mg N L-1 day-1 on day 228, and maintained a stable level (~ 420 mg N L-1 day-1) following introduction of SHARON effluent since day 229. Correlation between microbial community dynamics and nitrogen removal capability was significant (r = 0.489, p < 0.001). Microbial community composition was determined by influent ammonia, influent nitrite, effluent nitrate and some undefined factors. Anammox bacteria, accounting for ~ 98.7% of Planctomycetes, became detectable (0.03% relative abundance) since day 38 and increased to 0.9% on day 58, well consistent with nitrogen removal performance of the reactor. Relative abundance of anammox bacteria gradually increased to 38.4% on day 140 with stepwise increased influent load; decreased to 0.4% on day 169 because of nitrite inhibition; increased to 19.24% on day 233 when the influent load was dropped; kept at ~ 9.0% with SHARON effluent used as influent and dropped to 3.3% finally. Anammox bacteria, only Candidatus Brocadia and Ca. Kuenenia detected, were the most abundant at genus level. Ca. Brocadia related taxa were enriched firstly under low load and detectable during the entire experimental period. Three main groups represented by Ca. Brocadia related OTUs were enriched or eliminated at different loads, but Ca. Kuenenia related taxa were enriched only under high load (NO2--N > 300 mg/L), suggesting their different niches and application for different loads. These findings improve the understanding of relationships among microbial community/functional taxa, running parameters and reactor performance, and will be useful in optimizing running parameters for rapid startup and high, stable efficiency. PMID- 30276500 TI - Early onset of efficacy with erenumab in patients with episodic and chronic migraine. AB - BACKGROUND: Subcutaneous erenumab reduced monthly migraine days and increased the likelihood of achieving a >= 50% reduction at all monthly assessment points tested in 2 pivotal trials in episodic migraine (EM) and chronic migraine (CM). Early efficacy of migraine preventive medications is an important treatment characteristic to patients. Delays in achievement of efficacy can result in failed adherence. The objective of these post-hoc analyses were to evaluate efficacy in the first 4 weeks after initial subcutaneous administration of erenumab 70 mg, erenumab 140 mg, or placebo. METHODS: There is no generally accepted methodology to measure onset of action for migraine preventive medications. We used a comprehensive approach with data from both studies to evaluate change from baseline in weekly migraine days (WMD), achievement of >= 50% reduction in WMD, and proportion of patients experiencing migraine measured on a daily basis. The 7-day moving averages were overlaid with observed data. RESULTS: In both studies (EM: N = 955; CM: N = 667), there was evidence of onset of efficacy of erenumab vs. placebo during the first week of treatment, which in some cases reached nominal significance. For EM the changes in WMD were (least squares mean [LSM] [95% CI]): placebo, - 0.1 (- 0.3, 0.0); erenumab 70 mg, - 0.3 (- 0.5, - 0.2) p = 0.130; erenumab 140 mg, - 0.6 (- 0.7, - 0.4) p < 0.001. For CM the changes were: placebo, - 0.5 (- 0.8, - 0.3); erenumab 70 mg, - 0.9 (- 1.2, - 0.7) p = 0.047; erenumab 140 mg, - 0.8 (- 1.1, - 0.5) p = 0.18. Achievement of >= 50% reduction in WMD was observed as early as Week 1 (adjusted OR [95% CI] erenumab vs placebo) in EM: erenumab 70 mg, 1.3 (1.0, 1.9) p = 0.097; erenumab 140 mg, 2.0 (1.4, 2.7) p < 0.001. A similar outcome was observed for CM: erenumab 70 mg, 1.8 (1.1, 2.8) p = 0.011; erenumab 140 mg, 1.9 (1.2, 2.9) p = 0.009. Seven day moving averages of observed data showed each treatment arm differed from placebo by Week 1 (OR [95% CI]): in EM Day 3 for erenumab 140 mg, 0.7 (0.5, 1.0) p = 0.031 and at Day 7 for 70 mg, 0.6 (0.4, 0.8) p = 0.002; in CM: Day 6 for erenumab 70 mg, 0.6 (0.4, 0.9) p = 0.022 and at Day 7 for 140 mg, 0.7 (0.4, 1.0); p = 0.038. CONCLUSION: Erenumab showed early onset of efficacy with separation from placebo within the first week of treatment in both chronic and episodic migraine patients. PMID- 30276501 TI - Single center study of 53 consecutive patients with pituitary stalk lesions. AB - BACKGROUND: The etiological spectrum of pituitary stalk lesions (PSL) is wide and yet specific compared to the other diseases of the sellar and suprasellar region. Because of the pituitary stalk's (PS) critical location and role, biopsies of these lesions are rarely performed, and their underlying pathology is often a conundrum for clinicians. A pituitary MRI in association with a clinical context can facilitate their diagnosis. AIM: To present the various causes of PSL-their clinical, hormonal, histopathological, and MRI characteristics in order to gain better insight into this pathology. METHOD: A retrospective observational study consisting of 53 consecutive patients with PSL of the mean age 32 +/- 4.2 years (range 6-67), conducted at the Department for Neuroendocrinology, Clinical Center of Serbia 2010-2018. RESULTS: Congenital malformations were the most common cause of PSL in 25 of 53 patients (47.1%), followed by inflammatory (9/53; 16.9%) and neoplastic lesions (9/53; 16.9%). The exact cause of PSL was established in 31 (58.4%) patients, of whom 23 were with congenital PS abnormalities and 8 with histopathology of PSL (7 neoplastic and 1 Langerhans Cell Hystiocytosis). A probable diagnosis of PSL was stated in 12 patients (22.6%): 6 with lymphocytic panhypophysitis, while Rathke cleft cyst, tuberculosis, dissemination of malignancy in PS were each diagnosed in 2 patients. In 10 patients (18.8%), the etiology of PSL remained unknown. CONCLUSION: Due to the inability of establishing an exact diagnosis, the management and prognosis of PSL are difficult in many patients. By presenting a wide array of causes implicated in this condition, we believe that our study can aid clinicians in the challenging cases of this pathology. PMID- 30276502 TI - Force matching as a stepping stone to QM/MM CB[8] host/guest binding free energies: a SAMPL6 cautionary tale. AB - Use of quantum mechanical/molecular mechanical (QM/MM) methods in binding free energy calculations, particularly in the SAMPL challenge, often fail to achieve improvement over standard additive (MM) force fields. Frequently, the implementation is through use of reference potentials, or the so-called "indirect approach", and inherently relies on sufficient overlap existing between MM and QM/MM configurational spaces. This overlap is generally poor, particularly for the use of free energy perturbation to perform the MM to QM/MM free energy correction at the end states of interest (e.g., bound and unbound states). However, by utilizing MM parameters that best reproduce forces obtained at the desired QM level of theory, it is possible to lessen the configurational disparity between MM and QM/MM. To this end, we sought to use force matching to generate MM parameters for the SAMPL6 CB[8] host-guest binding challenge, classically compute binding free energies, and apply energetic end state corrections to obtain QM/MM binding free energy differences. For the standard set of 11 molecules and the bonus set (including three additional challenge molecules), error statistics, such as the root mean square deviation (RMSE) were moderately poor (5.5 and 5.4 kcal/mol). Correlation statistics, however, were in the top two for both standard and bonus set submissions ([Formula: see text] of 0.42 and 0.26, [Formula: see text] of 0.64 and 0.47 respectively). High RMSE and moderate correlation strongly indicated the presence of systematic error. Identifiable issues were ameliorated for two of the guest molecules, resulting in a reduction of error and pointing to strong prospects for the future use of this methodology. PMID- 30276504 TI - The Integrated Health Hub (IHH) Model: The Evolution of a Community Based Primary Care and Mental Health Centre. AB - There is increasing demand for comprehensive community healthcare that integrates community mental health and primary care services. The Canadian Mental Health Association-Durham Branch provides an example of how the Integrated Health Hub (IHH) Model evolved organically to meet this need. The Framework Method was used to analyze interviews and focus groups with 29 participants. Results reveal five key domains critical to the development of the IHH Model (1) Communication; (2) Hub 'Nuances'; (3) Leadership; (4) Staff; and (5) Challenges. These findings provide insights for other community mental health organizations wishing to provide comprehensive integrated community healthcare services. PMID- 30276503 TI - An explicit-solvent hybrid QM and MM approach for predicting pKa of small molecules in SAMPL6 challenge. AB - In this work we have developed a hybrid QM and MM approach to predict pKa of small drug-like molecules in explicit solvent. The gas phase free energy of deprotonation is calculated using the M06-2X density functional theory level with Pople basis sets. The solvation free energy difference of the acid and its conjugate base is calculated at MD level using thermodynamic integration. We applied this method to the 24 drug-like molecules in the SAMPL6 blind pKa prediction challenge. We achieved an overall RMSE of 2.4 pKa units in our prediction. Our results show that further optimization of the protocol needs to be done before this method can be used as an alternative approach to the well established approaches of a full quantum level or empirical pKa prediction methods. PMID- 30276505 TI - Determinants for quality of life trajectory patterns in patients with type 2 diabetes. AB - PURPOSE: The purpose of the study was to identify quality of life (QoL) trajectory patterns and the determinants in patients with Type 2 diabetes (T2DM). METHODS: A longitudinal design was employed. Totally, 466 patients with T2DM recruited from five diabetic clinics in Taiwan were participants of this study. Demographic and disease characteristics, biomedical factors (HbA1c levels and body mass index), psychosocial factors (self-care behaviors, social support, resilience, diabetes distress), and QoL were collected at baseline. QoL was further measured every 6 months for four waves after baseline. Latent class growth analysis was used to identify QoL trajectory patterns. The multinomial logistic regression was further applied to explore the important determinants of different QoL trajectory patterns. RESULTS: The "steadily poor" (n = 27, 5.8%), "consistently moderate" (n = 174, 37.3%), and "consistently good" (n = 265, 56.9%) trajectory patterns were identified. The HbA1c levels (OR 2.16) and diabetes distress (OR 1.18) were important for determining participants in the "steadily poor" QoL trajectory pattern. HbA1c levels (OR 1.25) and diabetes distress (OR 1.14) were important for determining participants in the "consistently moderate" QoL trajectory pattern. CONCLUSIONS: To prevent development of relatively worse QoL trajectory patterns in patients with T2DM in a timelier manner, healthcare providers could regularly assess the QoL and provide intervention, especially for those with high HbA1c levels and high diabetes distress. Meanwhile, early intervention for decreasing HbA1c levels and diabetes distress may improve the trajectory development of QoL in patients with T2DM. PMID- 30276506 TI - Psychometric properties of a modified version of the Weiss Functional Impairment Rating Scale-Parent Report (WFIRS-P) in a clinical sample of children with aggressive behavior. AB - PURPOSE: To evaluate the psychometric properties of a German modification of the Weiss Functional Impairment Rating Scale-Parent Report for children with aggressive and oppositional behavior problems (WFIRS-P for ODD/CD). METHODS: Data were collected from a clinical sample of children (6-12 years; 96% boys) with oppositional defiant disorder (ODD) and conduct disorder (CD) (N = 219). The WFIRS-P conceptual framework was evaluated using confirmatory factor analyses (CFA). Reliability was estimated using internal consistency (Cronbach's alpha) and omega statistics. Validity was assessed through correlations between WFIRS-P for ODD/CD domain scores and parent-rated scales on symptoms of ODD, CD, attention-deficit/hyperactivity disorder (ADHD), a broad range of other behavioral and emotional problems, and scales on health-related quality of life and family burden. RESULTS: CFA of the WFIRS-P for ODD/CD revealed that a bifactor model, with a general factor accounting for common variance (omegaH = 0.23-0.48) and independent specific group factors accounting for additional variance in item scores (omegaS = 0.37-0.60), best fits the data. Thus, CFA confirmed the theoretical assumption of a general construct of impairment (total scale) and additional specific impairments (subscales, e.g., family, social activities). Cronbach's alpha coefficient exceeded 0.70 for all subscales. Omega statistics showed that both the general construct and specific factors accounted for item variance. As expected, correlations with symptoms scales for ODD/CD and ADHD were low to moderate. CONCLUSIONS: The use of the parent-rated WFIRS for ODD/CD in identifying ODD- and CD-related impairment in children is psychometrically supported. The scale can be employed to assess functional impairment in children with aggressive behavior problems. PMID- 30276507 TI - MiR-539 Targets MMP-9 to Regulate the Permeability of Blood-Brain Barrier in Ischemia/Reperfusion Injury of Brain. AB - Cerebral ischemia/reperfusion (I/R) injury severely threatens human life, while the potential mechanism underlying it is still need further exploration. The rat model of cerebral I/R injury was established using middle cerebral artery occlusion (MCAO). The rat microvascular endothelial cell line bEND.3 was exposed to oxygen-glucose deprivation/reperfusion (OGD/R) to mimic ischemic condition in vitro. Evans blue was performed to determine the blood-brain barrier (BBB) permeability. Real-time PCR and western blot were performed to determine gene expression in mRNA and protein level, individually. Luciferase reporter assay was conducted to determine the relationship between miR-539 and MMP-9. The infarct volume and BBB permeability of cerebral (I/R) rats were significantly greater than Sham group. The expression of miR-539 was decreased, while MMP-9 was increased in the brain tissues of I/R injury rats and OGD/R pretreated bEND.3. Up regulated miR-539 in OGD/R pretreated bEND.3 significantly promoted the BBB permeability. MiR-539 targets MMP-9 to regulate its expression. OGD/R treatment significantly promoted the BBB permeability in bEND.3, miR-539 mimic transfection abolished the effects of OGD/R, while co-transfected with pcDNA-MMP-9 abolished the effects of miR-539 mimic. MiR-539 targets MMP-9 and further regulates the BBB permeability in cerebral I/R injury. PMID- 30276508 TI - Reaching Uninsured Overweight and Obese Children Through the FitKids Mobile Lifestyle Modification Program: Lessons Learned. AB - The US prevalence of childhood obesity remains high with ~ 1 in five children diagnosed with obesity, and rates of obesity are likely higher in uninsured and Medicaid populations than in those with private insurance. To understand the impact of an obesity intervention, an established mobile clinic program conducted a study to determine whether a FitKids Mobile Lifestyle Modification Program could reach overweight and obese uninsured children. Eighty-six children (ages 8 18 years) participated in the FitKids study over two trial periods. The first trial consisted of four total visits, but subsequent visits after the initial visit had poor turnout. Through telephonic interviews, parents described positive aspects of the program: (1) providers' individual attention to their child, (2) increased knowledge about obesity, nutrition, and diet, (3) and parent and child were motivated to be more active. The most common barriers noted for return visits were (1) personal/family factors, (2) scheduling issues, and (3) distance to the clinic. As quality improvement, for the second trial, total number of visits was reduced from 4 to 3 visits and reminder calls were instituted. Percentage of children who returned for the third visit (67.5% for Trial 1 and 62.5% for Trial 2) was not improved despite quality improvement interventions. Mobile clinics provide a unique solution to reach underserved overweight and obese children to help them create a more active and healthy lifestyle, but more research is needed to understand how best to optimize programs. PMID- 30276509 TI - NLRP3/Caspase-1 Pathway-Induced Pyroptosis Mediated Cognitive Deficits in a Mouse Model of Sepsis-Associated Encephalopathy. AB - Sepsis-associated encephalopathy (SAE) is a common complication that leads to long-term cognitive impairments and increased mortality in sepsis survivors. The mechanisms underlying this complication remain unclear and an effective intervention is lacking. Accumulating evidence suggests the nucleotide-binding domain-like receptor protein3 (NLRP3)/caspase-1 pathway is involved in several neurodegenerative diseases. Thus, we hypothesized that the NLRP3/caspase-1 pathway is involved in NLRP3-mediated pyroptosis, maturation and release of inflammatory cytokines, and cognitive deficits in SAE. We used the NLRP3 inhibitor MCC950 and the caspase-1 inhibitor Ac-YVAD-CMK to study the role of the NLRP3/caspase-1 pathway in pyroptosis and cognitive deficits in a mouse model of SAE. Mice were randomly assigned to one of six groups: sham+saline, sham+MCC950, sham+Ac-YVAD-CMK, cecal ligation and puncture (CLP)+saline, CLP+MCC950, and CLP+Ac-YVAD-CMK. Surviving mice underwent behavioral tests or had hippocampal tissues collected for histochemical analysis and biochemical assays. Our results show that CLP-induced hippocampus-dependent memory deficits are accompanied by increased NLRP3 and caspase-1 positive cells, and augmented protein levels of NLRP3, caspase-1, gasdermin-D, and pro-inflammatory cytokines in the hippocampus. In addition, administration of MCC950 or Ac-YVAD-CMK rescues cognitive deficits and ameliorates increased hippocampal NLRP3-mediated neuronal pyroptosis and pro inflammatory cytokines. Our results suggest that the NLRP3/caspase-1 pathway induced pyroptosis mediates cognitive deficits in a mouse model of SAE. PMID- 30276510 TI - Normative Pentacam anterior and posterior corneal elevation measurements: effects of age, sex, axial length and white-to-white. AB - PURPOSE: To provide normal corneal elevation data for a large Caucasian population and to determine the impacts on these data of age, sex, axial length (AXL) and horizontal white-to-white (WW). SETTING: Centro Internacional de Oftalmologia Avanzada, Madrid, Spain. DESIGN: Retrospective, cross-sectional, observational. METHODS: In this retrospective, cross-sectional, observational study, anterior and posterior corneal elevations were measured in 789 right eyes of subjects with no ocular disease at the thinnest corneal location in relation to a fixed 8-mm best-fit sphere using the Pentacam, and AXL and WW were measured with the IOLMaster. A multiple linear regression model was used to assess the effects of age, sex, AXL and WW on the elevation data. RESULTS: Mean subject age was 50.5 +/- 15 years (range 17-93 years); 64% were women. Mean anterior and posterior corneal elevations were 1.99 +/- 1.75 um (- 7 to 10 um) and 7.70 +/- 5.7 um (- 6 to 28 um). Anterior corneal elevations were higher by 0.165 MUm and 0.033 MUm for every mm reduction in AXL and every year reduction in age, respectively. Sex and WW were not significant predictors of anterior elevations (R2 = 7.7%). Posterior corneal elevation increased by 0.186 MUm/year of age, 0.707 MUm/mm reduction in WW and 0.819 MUm/mm reduction in AXL. This variable was also 0.866 MUm greater in men (R2 = 34.4%). CONCLUSION: Anterior corneal elevations decrease with age and are higher for shorter AXL but are not influenced by sex or WW. Posterior corneal elevations increase with age, decreasing AXL, decreasing WW and are higher in men. PMID- 30276511 TI - An unusual synthesis of 3-(2-(arylamino)thiazol-4-yl)-2H-chromen-2-ones from ethyl 2-(chloromethyl)-2-hydroxy-2H-chromene-3-carboxylate via benzopyran ring opening. AB - An unusual and unexpected synthesis of 3-(2-(arylamino)thiazol-4-yl)-2H-chromen-2 ones has been observed by the reaction of ethyl 2-(chloromethyl)-2-hydroxy-2H chromene-3-carboxylate with various arylthioureas in ethanol under mild reaction conditions with excellent yields. The ambiguity in the structure of the obtained products has been solved by recording its single-crystal X-ray analysis. This protocol has been found to be a novel approach for the preparation of title compounds via benzopyran ring opening. A systematic plausible mechanism has been proposed for the formation of the product. Also, an efficient one-pot three component method has been demonstrated for the formation of title compounds starting from salicylaldehyde. PMID- 30276512 TI - Risk assessment of vascular disorders by a supplementary hand-arm vascular weighting of hand-transmitted vibration. AB - PURPOSE: To provide an updated epidemiological validation for a supplementary method for assessing the risk of vascular disorders from hand-transmitted vibration. METHODS: The occurrence of vibration-induced white finger (VWF) in the vibration-exposed workers of the Italian cohort of the EU VIBRISKS study was related to measures of daily vibration exposure expressed in terms of r.m.s. acceleration magnitude normalised to an 8-h day, frequency weighted according to either the frequency weighting Wh defined in international standard ISO 5349 1:2001 [Ah(8) in ms- 2] or the hand-arm vascular frequency weighting Wp proposed in the ISO technical report (TR) 18570:2017 [Ap(8) in ms- 2]. To estimate a threshold value for vascular hand-arm vibration risk, the Wp-weighted vibration exposure value Ep,d (in ms- 1.5) was calculated according to the ISO/TR document. The difference in the predictions of VWF between the exposure measures calculated with the frequency weightings Wh or Wp was investigated by means of logistic modelling. RESULTS: Measures of daily vibration exposure constructed with the frequency weighting Wp [Ap(8) and Ep,d], which gives more importance to intermediate- and high-frequency vibration, were better predictors of the occurrence of VWF in the vibration-exposed workers than the metric derived from the conventional ISO frequency weighting Wh [Ah(8)]. There was some epidemiological evidence for a threshold value of Ep,d for the onset of VWF in the vibration-exposed workers. CONCLUSIONS: Measures of daily vibration exposure evaluated with the vascular weighting Wp performed better for the predictions of VWF than those obtained with the frequency weighting Wh recommended in ISO 5349 1. PMID- 30276513 TI - VOC sources and exposures in nail salons: a pilot study in Michigan, USA. AB - PURPOSE: Exposures of nail salon technicians have received attention due to the potentially toxic materials used in nail products, which include volatile organic compounds (VOCs) such as formaldehyde and methyl methacrylate (MMA). This study characterized area and personal concentrations and other indoor air parameters in 17 nail salons in fall and winter seasons in three areas of Michigan. METHODS: VOC samples were analyzed using thermal desorption, gas chromatography and mass spectroscopy, and the VOC composition of 35 nail products (e.g., polish, top coat, base coat) was measured using headspace sampling. Ventilation rates were derived using CO2 concentrations, occupancy and building information, and VOC sources were apportioned by a novel application of chemical mass balance models. RESULTS: We detected ethyl acetate, propyl acetate, butyl acetate, MMA, n-heptane and toluene in most salons, and benzene, D-limonene, formaldehyde, and ethyl methacrylate in some salons. While MMA was not measured in the consumer and professional products, and the use of pure MMA in salons has been not been permitted since the 1970s, MMA was found in air at concentrations from 100 to 36,000 ug/m3 in 15 of 17 salons; thus its use appears to be commonplace in the industry. Personal measurements, representing exposures to workers and clients, were about twice those of the area measurements for many VOCs. CONCLUSION: This study identifies the products responsible for emissions, shows the widespread presence of MMA, and documents low ventilation rates in some salons. It also demonstrates that "informal" short-term sampling approaches can evaluate chemical exposures in nail salons, providing measurements that can be used to protect a potentially susceptible and vulnerable population. Additional controls, including restrictions on the VOC compositions and improved ventilation, can reduce exposures to salon workers and clients. PMID- 30276514 TI - Postoperative morbidity of free flaps in head and neck cancer reconstruction: a report regarding 215 cases. AB - OBJECTIVES: The aim of this study was to identify the factors responsible for free flap failure, the surgical complications, and the non-oral feeding period in patients treated for an oral squamous cell carcinoma. MATERIALS AND METHODS: This multicentric study included 215 patients treated by tumour resection with immediate free flap reconstruction for an OSCC between 2010 and 2016. All of the patient medical files were reviewed and the data regarding the patient medical history, the tumour-related features, the surgical procedure, and the postoperative recovery were compiled. A statistical analysis with univariate and multivariate logistic regression was carried out. RESULTS: The free flap success rate was 94.4% in our series. A postoperative complication occurred in 101 patients (41%). Minor surgical complications were shown to increase the free flap failure rate (OR 3.32; p = 0.04). A major surgical complication was encountered in 48 patients (22.3%), and these were linked to minor surgical complications (OR 2.89; p = 0.004) and the use of a tracheostomy (OR 5.76, p = 0.002). Conversely, a medical history of high blood pressure had a protective effect (p = 0.04). The non-oral feeding rate at the end of the hospital stay was 28.4%, and it correlated with the tracheostomy (p = 0.002), as well as the major and the minor surgical complications (p = 0.04). CONCLUSION-CLINICAL RELEVANCE: Free flap reconstruction is a safe and reliable technique with head and neck cancer reconstruction. Postoperative care favouring early and safe oral-feeding, and avoiding a tracheostomy can reduce the incidence of surgical complications after OSCC reconstruction. PMID- 30276515 TI - Periodontal outcome and additional clinical quality criteria of lithium disilicate restorations (Empress 2) after 14 years. AB - OBJECTIVES: To evaluate the clinical quality of tooth-supported crowns (SCs), implant-supported crowns (ISCs), and fixed dental prosthesis (FDPs) made of a lithium-disilicate glass-ceramic framework material (IPS Empress 2, Ivoclar Vivadent) after long-term use. MATERIALS AND METHODS: Between 1997 and 1999, 184 restorations (106 SCs, 32 ISCs, 33 FDPs, 13 diverse restorations) were placed in 73 patients. In 2012/2013, all patients with functioning restorations were invited to participate in a clinical follow-up examination. To investigate the clinical quality, modified California Dental Association (CDA) criteria, periodontal health, and the patient's opinion were evaluated. RESULTS: After 14 years on average, 50 restorations were available for evaluation of the CDA criteria and the patient's opinion, and 24 restorations were available for the periodontal health evaluation. Surface, color, anatomic shape, and margin integrity were considered to be in the range of excellence in 54, 78, 96, and 88%, respectively. There were no unacceptable defects. Most patients (64%) were still entirely satisfied with their restorations. Mean probing depths were significantly higher on teeth with tooth-supported Empress 2 restorations than on control teeth (p = 0.0401). No significant relationship was found between surface quality and plaque accumulation (p = 0.9450, generalized linear mixed model) or between surface quality and periodontal probing >= 4 mm (p = 0.4184, generalized linear mixed model). CONCLUSIONS: The clinical quality of the Empress 2 restorations that had survived 14 years on average was totally satisfactory with regard to esthetics, design, and patient's opinion. The periodontal health of all ceramic restored teeth requires further investigation. CLINICAL SIGNIFICANCE: The practitioner's choice of dental materials is based, at best, on long-term experience. With diminishing concerns about the clinical longevity of all-ceramic restorations, the grading of clinical quality based on esthetics, design, periodontal response, and patients' opinions could, nowadays, serve as a measure for the efficiency of dental ceramic. PMID- 30276516 TI - Microbial diversity in infections of patients with medication-related osteonecrosis of the jaw. AB - OBJECTIVES: A central role of infections in the treatment of MRONJ patients is widely accepted. An investigation of the MRONJ lesions' biofilms as potential pathogens seems logical. MATERIALS AND METHODS: We investigated the clinical data of our MRONJ patients who received surgery in advanced stage of the disease. Special attention was granted to the local colonizers harvested from osseous MRONJ specimens and submucosal putrid infections. RESULTS: Eleven out of 71 patients presented a spontaneous onset of the disease and for 60 out of 71 patients a trigger was detected. Breast cancer (29.6%) and prostate cancer (22.5%) were the most frequent underlying disease for prescription of an antiresorptive therapy, mostly zoledronate. Submucosal soft tissue biofilms significantly differed from biofilms harvested from the MRONJ lesions bottom, yet the most frequent bacteria were equally present in both groups: Streptococcus species (spp.), Prevotella spp., Actinomyces spp., Veillonella spp., and Parvimonas micra. The cephalosporins, cefuroxime and cefotaxime, and beta-lactam antibiotics with beta-lactamase inhibitor revealed the greatest susceptibility for the detected bacteria. CONCLUSION: The bacteria from the submucosal areas and the bottom of the infected bone presented comparable susceptibility to the common antibiotics regimes. Streptococcus spp., Prevotella spp., and Veillonella spp. present a high abundance in MRONJ lesions beside Actinomyces spp. The MRONJ lesions bottom is in many cases not infected by Actinomyces spp. CLINICAL RELEVANCE: The removal of the necrotic bone reduces the variety of bacteria found in MRONJ lesions, in particular at the bottom of the lesion. PMID- 30276517 TI - Oral symptoms and oral health-related quality of life in patients with chronic kidney disease from predialysis to posttransplantation. AB - OBJECTIVE: This prospective follow-up cohort study analyzed chronic kidney disease (CKD) patients' oral symptoms, health habits, and oral health-related quality of life (OHRQoL), from predialysis to posttransplantation. A simplified questionnaire method (Oral Health Quality Score, OHQS), based on these and clinical findings, was constructed and tested for identifying patients in need for referral to a dentist. MATERIAL AND METHODS: Fifty-three CKD patients were followed up for a mean of 10.3 years. Clinical oral, radiological, and salivary examination was performed at baseline and posttransplantation. Total Dental Index (TDI) indicating inflammation was calculated. The patients filled out a questionnaire on symptoms, oral hygiene and health care habits, smoking, alcohol use, and medication. General health-related quality of life was assessed with the 15-dimensional (15D) instrument at posttransplantation. Descriptive and analytical methods were used in statistics. RESULTS: OHQS significantly correlated with high TDI (p = 0.017), number of teeth (p = 0.031), and unstimulated salivary flow rate (p = 0.001) in transplanted patients. Number of daily medications showed a negative correlation with the OHQS (r = - 0.30; p = 0.028). The prevalence of oral symptoms was slightly, but not significantly, more common posttransplantation compared with predialysis stage. CONCLUSION: OHQS identified patients with high oral inflammatory score thus confirming our study hypothesis. CLINICAL RELEVANCE: Use of OHQS and measuring salivary flow indicate patients at risk for oral diseases. These markers might be easy to use chair-side also by auxiliary personnel. PMID- 30276518 TI - Gerald M. Edelman (1929-2014). PMID- 30276519 TI - Effect of mechanical thrombectomy alone or in combination with intravenous thrombolysis for acute ischemic stroke. AB - OBJECTIVE AND DESIGN: Whether combining intravenous thrombolysis (IVT) and mechanical thrombectomy (MT) is superior to mechanical thrombectomy alone for large vessel occlusion acute ischemic stroke is still uncertain. Our aim was to compare the safety and the efficacy of these two therapeutic strategies. MATERIALS: Patients with acute ischemic stroke secondary to anterior circulation large vessel occlusion. METHODS: A retrospective analysis was conducted. IVT was performed with full dose recombinant tissue plasminogen activator. MT alone was performed only if intravenous thrombolysis was contraindicated. Primary outcomes were successful reperfusion, 3-month functional independence, symptomatic intracranial hemorrhage (sICH), and 3-month mortality. RESULTS: 325 patients were analyzed: 193 treated with combined IVT and MT, 132 with MT alone. The combined treatment group showed higher systolic blood pressure (140 [80-230] vs 150 [90 220]; p = 0.036), rate of good collaterals (55.9% vs 67%; p = 0.03), use of aspiration devices (68.2% vs 79.3%; p = 0.003) and shorter onset-to-reperfusion time (300 [90-845] vs 288 [141-435]; p = 0.008). No differences were found in the efficacy and safety outcomes except for mortality which was lower in the combined treatment group (36.4% vs 25.4%; p = 0.02). However, after multivariable analysis combined treatment was not associated with lower mortality (OR 1.47; 95% CI 0.73 2.96; p = 0.3). CONCLUSIONS: Our study suggests that mechanical thrombectomy alone is effective and safe in patients with contraindications to intravenous thrombolysis. Preceding use of IVT in eligible patients was not associated with increased harm or benefit. Randomized controlled trials are needed to clarify whether intravenous thrombolysis before mechanical thrombectomy is associated with additional benefit. PMID- 30276521 TI - Collaboration of Cerebello-Rubral and Cerebello-Striatal Loops in a Motor Preparation Task. AB - In this study, we used fMRI to identify brain regions associated with concentration (sustained attention) during a motor preparation task. In comparison with a non-concentration task, increased activities were observed (P < 0.05, FWE-corrected P values) in cerebellar lobules VI and VII, motor cortex, pre supplementary motor area (pre-SMA), thalamus, red nucleus (RN), and caudate nucleus (CN). Moreover, analysis of effective connectivity inter-areal (psychophysiological interactions) showed that during preparation, concentration related brain activity increase was dependent on Cerebello-thalamo-pre-SMA-RN and Pre-SMA-CN-thalamo-M1 loops. We postulate that, while pre-SMA common to both loops is specifically involved in the movement preparation and readiness for voluntary movement through the striatum, the cerebellar lobule VI in conjunction with RN, likely through a cerebellar-rubro-olivary-cerebellar loop, might be implicated in concentration-related optimization of upcoming motor performances.

AB - OBJECTIVE: To characterize the relation between brain functional connectivity and disability in patients with multiple sclerosis; to investigate the existence of critical values of both disability and functional connectivity corresponding to exhaustion of functional adaptive mechanisms. METHODS: Hundred-and-nineteen patients with no-to-severe disability and 42 healthy subjects were studied via 3T resting state functional MRI. Out of 116 regions extracted from Automated Anatomical Labeling atlas, pairs of regions whose functional connectivity correlated with Expanded Disability Status Score were identified. In patients, mathematical modeling was applied to find the best models describing Expanded Disability-Status-Score vs structural or functional measures. Functional vs structural models intersecting points were identified. RESULTS: Disability had direct linear relation with lesion load (r = 0.40, p < 5E-6), inverse of thalamic volume (r = 0.31 p < 1E-3) and functional connectivity in bi-frontal pairs of regions (r > 0.40, p < 0.04), while being non-linearly associated with functional connectivity in cerebello-temporal and cerebello-frontal pairs of regions (F > 1.73, p < 0.02). Structural vs functional models intersecting points corresponded to Expanded Disability Status Score of 3.0. 85% of patients scoring more than 3.0 showed functional connectivity in cerebello-temporal and cerebello-frontal pairs of regions below confidence intervals (z = [2.28-2.88] 95% CI) measured in healthy subjects. CONCLUSIONS: Functional brain connectivity changes may represent mechanisms of adaptation to structural damage and inflammation and may be not always clinically beneficial. Functional connectivity decreases in comparison with structural measure at Expanded Disability Status Score greater than 3.0, which may be critical and indicate exhaustion of compensatory mechanisms.

AB - PURPOSE: In iodine-sufficient areas, autoimmune hypothyroidism has been regarded as the major subtype of hypothyroidism. Non-immune-related hypothyroidism has received little attention because it is considered to be rare. The aim of this study was to evaluate the prevalence of non-immune-related hypothyroidism in Korea and to identify its associating factors. METHODS: A total of 6434 participants in the Korea National Health and Nutrition Examination Survey VI (2013-2015) without known thyroid disease who were examined for thyroid stimulating hormone, free thyroxine, TPO Ab, and urine iodine concentration (UIC) were enrolled. The weighted proportions, demographic variables, and severity of immune-related and non-immune-related hypothyroidism were compared. To assess the effect of iodine on hypothyroidism in TPO Ab positive or negative populations, the weighted prevalence of hypothyroidism was assessed in each population according to UIC or estimated iodine intake subgroups. RESULTS: The prevalence of undetected hypothyroidism in Korea was 3.8% (n = 233). Of these 233 cases, 171 (71.8%) were non-immune-related. In the TPO Ab negative population, the prevalence of hypothyroidism was increased significantly in the subgroup with UIC between 250 and 749 ug/L (HR 2.12 [1.17, 3.83]) and >= 750 ug/L (HR 3.42 [1.93, 6.04]) or the subgroups with estimated iodine intake >= 750 ug/day (HR 2.81 [1.64, 4.80]). CONCLUSIONS: This nationwide study demonstrated that most cases of hypothyroidism in iodine-sufficient areas are non-immune-related and are associated with excess iodine above a certain level. More attention to this unrecognized but widespread potential health risk is needed. PMID- 30276522 TI - Cerebellar Cortex as a Therapeutic Target for Neurostimulation. AB - Non-invasive stimulation of the cerebellum is growingly applied both in the clinic and in research settings to modulate the activities of cerebello-cerebral loops. The anatomical location of the cerebellum, the high responsiveness of the cerebellar cortex to magnetic/electrical stimuli, and the implication of the cerebellum in numerous cerebello-cerebral networks make the cerebellum an ideal target for investigations and therapeutic purposes. In this mini-review, we discuss the potentials of cerebellar neuromodulation in major brain disorders in order to encourage large-scale sham-controlled research and explore this therapeutic aid further.

PMID- 30276525 TI - Longitudinal echocardiographic and clinical follow-up of patients undergoing mitral valve surgery without concomitant tricuspid valve repair. AB - BACKGROUND: In patients with mild to moderate functional tricuspid regurgitation (TR) and absence of right ventricular dysfunction or tricuspid annulus (TA) dilatation, there is currently no indication for concomitant tricuspid valve (TV) repair during elective mitral valve (MV) surgery. However, long-term results are conflicting. Here, we sought to determine the clinical outcome of this cohort, the rate of TR progression after MV surgery and the role of MV aetiology. METHODS: Patients for elective MV surgery without concomitant TV repair were retrospectively analysed with longitudinal echocardiographic and clinical follow up, focusing on TR progression and MV aetiology. Linear regression analysis was performed for change in TR at follow-up, using pre-determined variables and confounders. RESULTS: In total 204 patients without TV repair were analysed. Development of more than moderate TR after a median of 3.1 [1.6-4.6] years was rarely seen: only in 2 out of 161 patients (1.2%) with known TR grade at follow up. Overall, median preoperative and late postoperative TR grade were equal (p = 0.116). Subanalysis showed no significant difference in MV aetiology subgroups. Preoperative TR grade and male gender were inversely correlated to change in TR. Mortality was not influenced by the 1-year postoperative TR severity. CONCLUSION: Our data showed that in a study population of patients with mild to moderate TR undergoing MV surgery without concomitant TV repair, significant late TR was rarely seen. Based on our study, it is safe to waive concomitant TV repair in this specific patient cohort. PMID- 30276527 TI - Intermedin in Paraventricular Nucleus Attenuates Sympathoexcitation and Decreases TLR4-Mediated Sympathetic Activation via Adrenomedullin Receptors in Rats with Obesity-Related Hypertension. AB - Intermedin/adrenomedullin-2 (IMD/AM2), a member of the calcitonin gene-related peptide/AM family, plays an important role in protecting the cardiovascular system. However, its role in the enhanced sympathoexcitation in obesity-related hypertension is unknown. In this study, we investigated the effects of IMD in the paraventricular nucleus (PVN) of the hypothalamus on sympathetic nerve activity (SNA), and lipopolysaccharide (LPS)-induced sympathetic activation in obesity related hypertensive (OH) rats induced by a high-fat diet for 12 weeks. Acute experiments were performed under anesthesia. The dynamic alterations of sympathetic outflow were evaluated as changes in renal SNA and mean arterial pressure (MAP) in response to specific drugs. Male rats were fed a control diet (12% kcal as fat) or a high-fat diet (42% kcal as fat) for 12 weeks to induce OH. The results showed that IMD protein in the PVN was downregulated, but Toll-like receptor 4 (TLR4) and plasma norepinephrine (NE, indicating sympathetic hyperactivity) levels, and systolic blood pressure were increased in OH rats. LPS (0.5 ug/50 nL)-induced enhancement of renal SNA and MAP was greater in OH rats than in obese or control rats. Bilateral PVN microinjection of IMD (50 pmol) caused greater decreases in renal SNA and MAP in OH rats than in control rats, and inhibited LPS-induced sympathetic activation, and these were effectively prevented in OH rats by pretreatment with the AM receptor antagonist AM22-52. The mitogen-activated protein kinase/extracellular signal-regulated kinase (ERK) inhibitor U0126 in the PVN partially reversed the LPS-induced enhancement of SNA. However, IMD in the PVN decreased the LPS-induced ERK activation, which was also effectively prevented by AM22-52. Chronic IMD administration resulted in significant reductions in the plasma NE level and blood pressure in OH rats. Moreover, IMD lowered the TLR4 protein expression and ERK activation in the PVN, and decreased the LPS-induced sympathetic overactivity. These results indicate that IMD in the PVN attenuates SNA and hypertension, and decreases the ERK activation implicated in the LPS-induced enhancement of SNA in OH rats, and this is mediated by AM receptors. PMID- 30276529 TI - Investigation of Vipera Anatolica Venom Disintegrin via Intracellular Uptake with Radiolabeling Study and Cell-Based Electrochemical Biosensing Assay. AB - Snake venoms are a natural biological source that has potential therapeutic value with various protein compounds. Disintegrins originally were discovered as a family of proteins from snake venoms composed of cysteine rich low molecular weight polypeptides. Disintegrins exhibit specific binding and higher affinity toward integrin with potential inhibition of function. Trans-membrane receptors of the integrin family may involve in many pathological conditions such as inflammation and tumor progression with important processes related to invasion and migration. Since disintegrins have the ability to bind to integrins, they could be used for cancer detection and treatment, and in monitoring of therapy in select cancer types. The main purpose of the study is to investigate disintegrin containing Vipera anatolica (VAT) crude venom potential for radiolabeling and intracellular uptake as well as electrochemical biosensing assay against U87MG human brain glioblastoma cells. For this purpose, VAT crude venom containing U87MG cell-specific disintegrin was investigated in terms of radiolabeling and intracellular uptake as well as electrochemical biosensing assay in comparison with echistatin (ECT) disintegrin in cells. The interaction between VAT crude venom and ECT with HEK293 human non-tumorigenic embryonic kidney cells and glioblastoma U87MG cells was electrochemically investigated using pencil graphite electrodes (PGEs). The interaction of the VAT crude venom and ECT with HEK293 and U87MG cells was detected according to the changes in oxidation signals. Then, VAT crude venom and echistatin were labeled with 131I via iodogen method. Intracellular uptakes of radiolabeled molecules were investigated in U87MG cell line. 131I-VAT can be an agent for imaging of glioblastoma cancer. Further work will focus on the production of large quantities of pure VAT disintegrin with a biotechnological approach to improving imaging agent. PMID- 30276528 TI - Chitosan/hyaluronic acid/plasmid-DNA nanoparticles encoding interleukin-1 receptor antagonist attenuate inflammation in synoviocytes induced by interleukin 1 beta. AB - Synovial inflammation mainly resulting from interleukin-1 beta (IL-1beta) plays a crucial role in the early and late stage of osteoarthritis. Recent progress in therapeutic gene delivery systems has led to promising strategies for local sustained target gene expression. The aim of this study was to design a nanoparticle made of chitosan (CS)/hyaluronic acid (HA)/plasmid-DNA (pDNA) encoding IL-1 receptor antagonist gene (pIL-1Ra) and furtherly use it to transfect the primary synoviocytes, and then investigate whether CS/HA/pIL-1Ra nanoparticles could make the synoviocytes overexpress functional IL-1Ra to attenuate inflammation induced by IL-1beta. In this study, CS was modified with HA to generate CS/HA nanoparticles and then combined with pIL-1Ra to form CS/HA/pIL-1Ra nanoparticles. The physicochemical characteristics results showed that CS/HA nanoparticles exhibited an appropriate particle size (144.9 +/- 2.8 nm) and positive zeta potential ( + 28 mV). The gel retardation assay revealed that pDNA was effectively protected and released in a sustained manner more than 15 days. Cytotoxicity results showed that CS/HA/pIL-1Ra nanoparticles had a safe range (0-80 MUg/ml) for the application to synoviocytes. RT-qPCR and western blot analysis demonstrated that CS/HA/pIL-1Ra nanoparticles were able to increase IL 1Ra expression in primary synoviocytes, and reduce the mRNA and protein levels of matrix metalloproteinase-3 (MMP-3), matrix metalloproteinase-13 (MMP-13), cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) in IL-1beta induced synoviocytes. Our findings indicated that CS/HA/pIL-1Ra nanoparticles efficiently transfected synoviocytes and attenuated synovitis induced by IL 1beta, which will provide a potential strategy for OA synovitis. PMID- 30276530 TI - Novel three-dimensional image system for endoscopic ear surgery. AB - OBJECTIVE: The objective of this study was to evaluate the clinical outcomes of conventional two-dimensional (2D) endoscope with a novel computer-based three dimensional (3D) imaging system for otologic surgical procedures. METHODS: A conventional 2D monocular endoscope with a novel computer-based 3D imaging system was applied to 18 otologic surgical procedures, including chronic otitis media (COM), cholesteatoma, otosclerosis, external canal osteoma and cochlear implant. Operation duration and complications of COM and attic cholesteatoma were recorded to compare 2D and 3D endoscopic ear surgery. Questionnaires were completed by 35 observers participating in the procedures and were used to evaluate clinical and potential side effects. RESULTS: The surgical procedures were performed smoothly for all patients. No patient required switching to conventional 2D endoscopic surgery. No significant differences were apparent in operation duration using the 3D imaging system for chronic otitis media and attic cholesteatoma compared with conventional 2D endoscopic ear surgery. Thirty-five observers completed the questionnaires. Most of them agreed that this 3D imaging system enabled them to perceive stereoscopic vision (94%), provide superior depth perception (85%). Furthermore, 97.1% reported no visual fatigue or discomfort when observing the 3D images. CONCLUSION: Our study demonstrated that the computer-based 3D imaging system enables the application of 3D vision technology to otologic surgery. The system has no obvious side effects, such as visual fatigue or time delay. It not only facilitates performing the related surgical procedures but also helps in teaching and learning endoscopic ear surgeries. PMID- 30276531 TI - Frozen shoulder or shoulder stiffness from Parkinson disease? AB - PURPOSE: To understand the role of camptocormia (increased kyphosis) and postural alteration in Parkinson's disease in the development of shoulder pathology, with a special concern for adhesive capsulitis and shoulder stiffness. METHODS: A preliminary online search was carried out, with combination of keywords including "Parkinson," "Shoulder stiffness," "Frozen shoulder," "Adhesive capsulitis," "Postural alteration," "Camptocormia". The retrieved papers were screened by title and abstract and those considered relevant to the aim of the review were read in full text and included. Relevant information were extracted and reported into text. RESULTS: Due to a severe impairment of posture, patients affected by PD show an increased thoracic kyphosis (camptocormia) and decreased mobility of the trunk that can yield a humeroacromial impingement syndrome and capsulitis, resulting in inflammation of the bursa, shoulder pain and reduction of movement. Furthermore, kinematic of the shoulder is allowed by the combined movement of the humerus, the scapula, the clavicle, the thoracic wall and thoracic spine. The thoracic spine and wall mobility are severely impaired in the parkinsonian patient, thus limiting the shoulder motion. CONCLUSION: The postural alteration observed in PD is the primum movens for shoulder pathology, since anterior tilt of the scapula, which occurs with the increment of thoracic kyphosis, yields to a subacromial impingement. A closed loop is then created, as the rigidity of the shoulder causes further alteration in the posture, which worsens the impingement syndrome and so on. PMID- 30276532 TI - Skin microvascular dysfunction as an early cardiovascular marker in primary hyperoxaluria type I. AB - BACKGROUND: Primary hyperoxaluria type 1 (PH1) is an orphan inborn error of oxalate metabolism leading to hyperoxaluria, progressive renal failure, oxalate deposition, and increased cardiovascular complications. As endothelial dysfunction and arterial stiffness are early markers of cardiovascular risk, we investigated early endothelial and vascular dysfunction in young PH1 patients either under conservative treatment (PH1-Cons) or after combined kidney liver transplantation (PH1-T) in comparison to healthy controls (Cont-H) and patients with a past of renal transplantation (Cont-T). METHODS: Skin microvascular function was non-invasively assessed by laser Doppler flowmetry before and after stimulation by current, thermal, or pharmacological (nitroprussiate (SNP) or acetylcholine (Ach)) stimuli in young PH1 patients and controls. RESULTS: Seven PH1-Cons (6 F, median age 18.2) and 6 PH1-T (2 F, median age 13.3) were compared to 96 Cont-H (51 F, median age 14.2) and 6 Cont-T (4 F, median age 14.5). The endothelium-independent vasodilatation (SNP) was severely decreased in PH1-T compared to Cont-H. Ach, current-induced vasodilatation (CIV), and thermal response was increased in PH1-Cons and Cont-T compared to controls. CONCLUSIONS: PH1-T patients displayed severely decreased smooth muscle capacity to vasodilate. An exacerbated endothelial-dependent vasodilation suggests a role for silent inflammation in the early dysfunction of microcirculation observed in PH1-Cons and Cont-T. PMID- 30276533 TI - Hypertensive crisis in children and adolescents. AB - Hypertensive crisis is a relatively rare condition in children. However, if not treated, it might be life-threatening and lead to irreversible damage of vital organs. Clinical presentation of patients with hypertensive crisis can vary from very mild (hypertensive urgency) to severe symptoms (hypertensive emergency) despite similarly high blood pressure (BP). Individualized assessment of patients presenting with high BP with emphasis on the evaluation of end-organ damage rather than on the specific BP number is a key in guiding physician's initial management of a hypertensive crisis. The main aim of the treatment of hypertensive crisis is the prevention or treatment of life-threatening complications of hypertension-induced organ dysfunction, including neurologic, ophthalmologic, renal, and cardiac complications. While the treatment strategy must be directed toward the immediate reduction of BP to reduce the hypertensive damage to these organs, it should not be at a too fast rate to cause hypoperfusion of vital organs by an excessively rapid reduction of BP. Thus, intravenous continuous infusions rather than intravenous boluses of antihypertensive medications should be the preferable mode of initial treatment of children with hypertensive emergency. PMID- 30276534 TI - Towards adulthood with a solitary kidney. AB - Around 1/1000 people have a solitary kidney. Congenital conditions mainly include multicystic dysplastic kidney and unilateral renal aplasia/agenesis; acquired conditions are secondary to nephrectomy performed because of urologic structural abnormalities, severe parenchymal infection, renal trauma, and renal or pararenal tumors. Children born with congenital solitary kidney have a better long-term glomerular filtration rate than those with solitary kidney secondary to nephrectomy later in life. Acute and chronic adaptation processes lead to hyperfiltration followed by fibrosis in the remnant kidney, with further risk of albuminuria, arterial hypertension, and impaired renal function. Protective measures rely on non-pharmacological renoprotection (controlled protein and sodium intake, avoidance/limitation of nephrotoxic agents, keeping normal body mass index, and limitation of tobacco exposure). Lifelong monitoring should include blood pressure and albuminuria assessment, completed by glomerular filtration rate (GFR) estimation in case of abnormal values. In the absence of additional risk factors to solitary kidney, such assessment can be proposed every 5 years. There is no current consensus for indication and timing of pharmacological intervention.

PMID- 30276536 TI - Comparison of echocardiographic changes in children with primary hypertension and hypertension due to mild to moderate chronic kidney disease. AB - BACKGROUND: Chronic systemic hypertension has a well-known association with increased cardiovascular morbidity and mortality. One of the most important target organs affected in systemic hypertension is the heart. In addition, chronic kidney disease (CKD) further increases the mortality from cardiovascular disease. The aim of this study was to evaluate the differences in the cardiovascular changes in pediatric patients with primary hypertension (pHTN) vs. those with secondary hypertension from chronic kidney disease (CKD-HTN). METHODS: This was a retrospective chart review of patients with CKD-HTN and pHTN. The medical records were reviewed for anthropometric data, biochemical assessment of renal function, and for cardiovascular changes on echocardiogram. RESULTS: Twenty three patients with pHTN and 29 patients with CKD-HTN were included in the study. There were no differences in age, gender, weight, height, body mass index, and blood pressure between the 2 groups. There was a high prevalence of left ventricular diastolic dysfunction among both the groups (CKD-HTN 25 vs. pHTN 26%). Reduced mitral valve inflow Doppler E/A ratio, a marker of left ventricular diastolic dysfunction in echocardiogram, was more pronounced in CKD-HTN patents, in comparison to those with pHTN (p = 0.042). Also, diastolic function worsened with declining glomerular filtration rate in patients with CKD-HTN. Similarly, patients with CKD-HTN had a larger aortic root dimension when compared to patients with pHTN (p = 0.049). CONCLUSIONS: The prevalence of left ventricular diastolic dysfunction is similar in patients with pHTN and CKD-HTN. Patients with CKD-HTN appear to have more severe diastolic dysfunction and larger aortic root dimensions. PMID- 30276539 TI - Land subsidence phenomena investigated by spatiotemporal analysis of groundwater resources, remote sensing techniques, and random forest method: the case of Western Thessaly, Greece. AB - The main objective of the present study was to investigate land subsidence phenomena and the spatiotemporal pattern of groundwater resources in an area located in western Thessaly, Greece, by using remote sensing techniques and data mining methods. Specifically, the nonparametric Mann-Kendall test and the Sen's slope estimator were used to estimate the trend concerning the groundwater table, whereas a set of Synthetic Aperture Radar images, processed with the Persistent Scatterer Interferometry technique, were used investigate the spatial and temporal patterns of ground deformation. Random forest (RF) method was utilized to predict the subsidence deformation rate based on three related variables, namely: thickness of loose deposits, the Sen's slope value of groundwater-level trend, and the Compression Index of the formation covering the area of interest. The outcomes of the study suggest a strong correlation among the thickness of the loose deposits and the deformation rate and also show that a clear trend between the deformation rate and the fluctuation of the groundwater table exists. For the RF model and based on the validation dataset, the r square value was calculated to be 0.7503. In the present study, the potential deformation rate assuming different water pumping scenarios was also estimated. It was observed that with a mean decrease in the Sen's slope value of groundwater-level trend of 20%, there would be a mean decrease of 9.01% in the deformation rate, while with a mean increase in the Sen's slope value of groundwater-level trend of 20%, there would be a mean increase of 12.12% in the deformation rate. The ability of identifying surface deformations allows the local authorities and government agencies to take measures before the evolution of severe subsidence phenomena and to prepare for timely protection of the affected areas. PMID- 30276537 TI - Replication of a rare risk haplotype on 1p36.33 for autism spectrum disorder. AB - Hundreds of genes have been implicated in autism spectrum disorders (ASDs). In genetically heterogeneous conditions, large families with multiple affected individuals provide strong evidence implicating a rare variant, and replication of the same variant in multiple families is unusual. We previously published linkage analyses and follow-up exome sequencing in seven large families with ASDs, implicating 14 rare exome variants. These included rs200195897, which was transmitted to four affected individuals in one family. We attempted replication of those variants in the MSSNG database. MSSNG is a unique resource for replication of ASD risk loci, containing whole genome sequence (WGS) on thousands of individuals diagnosed with ASDs and family members. For each exome variant, we obtained all carriers and their relatives in MSSNG, using a TDT test to quantify evidence for transmission and association. We replicated the transmission of rs200195897 to four affected individuals in three additional families. rs200195897 was also present in three singleton affected individuals, and no unaffected individuals other than transmitting parents. We identified two additional rare variants (rs566472488 and rs185038034) transmitted with rs200195897 on 1p36.33. Sanger sequencing confirmed the presence of these variants in the original family segregating rs200195897. To our knowledge, this is the first example of a rare haplotype being transmitted with ASD in multiple families. The candidate risk variants include a missense mutation in SAMD11, an intronic variant in NOC2L, and a regulatory region variant close to both genes. NOC2L is a transcription repressor, and several genes involved in transcription regulation have been previously associated with ASDs. PMID- 30276540 TI - A review on anti-adhesion therapies of bacterial diseases. AB - BACKGROUND: Infections caused by bacteria are a foremost cause of morbidity and mortality in the world. The common strategy of treating bacterial infections is by local or systemic administration of antimicrobial agents. Currently, the increasing antibiotic resistance is a serious and global problem. Since the most important agent for infection is bacteria attaching to host cells, hence, new techniques and attractive approaches that interfere with the ability of the bacteria to adhere to tissues of the host or detach them from the tissues at the early stages of infection are good therapeutic strategies. METHODS: All available national and international databanks were searched using the search keywords. Here, we review various approaches to anti-adhesion therapy, including use of receptor and adhesion analogs, dietary constituents, sublethal concentrations of antibiotics, and adhesion-based vaccines. RESULTS: Altogether, the findings suggest that interference with bacterial adhesion serves as a new means to fight infectious diseases. CONCLUSION: Anti-adhesion-based therapies can be effective in prevention and treatment of bacterial infections, but further work is needed to elucidate underlying mechanisms. PMID- 30276538 TI - De novo unbalanced translocations have a complex history/aetiology. AB - We investigated 52 cases of de novo unbalanced translocations, consisting in a terminally deleted or inverted-duplicated deleted (inv-dup del) 46th chromosome to which the distal portion of another chromosome or its opposite end was transposed. Array CGH, whole-genome sequencing, qPCR, FISH, and trio genotyping were applied. A biparental origin of the deletion and duplication was detected in 6 cases, whereas in 46, both imbalances have the same parental origin. Moreover, the duplicated region was of maternal origin in more than half of the cases, with 25% of them showing two maternal and one paternal haplotype. In all these cases, maternal age was increased. These findings indicate that the primary driver for the occurrence of the de novo unbalanced translocations is a maternal meiotic non disjunction, followed by partial trisomy rescue of the supernumerary chromosome present in the trisomic zygote. In contrast, asymmetric breakage of a dicentric chromosome, originated either at the meiosis or postzygotically, in which the two resulting chromosomes, one being deleted and the other one inv-dup del, are repaired by telomere capture, appears at the basis of all inv-dup del translocations. Notably, this mechanism also fits with the origin of some simple translocations in which the duplicated region was of paternal origin. In all cases, the signature at the translocation junctions was that of non-homologous end joining (NHEJ) rather than non-allelic homologous recombination (NAHR). Our data imply that there is no risk of recurrence in the following pregnancies for any of the de novo unbalanced translocations we discuss here. PMID- 30276541 TI - Does routine repeat imaging change management in high-grade renal trauma? Results from three level 1 trauma centers. AB - PURPOSE: Guidelines call for routine reimaging of Grade 4-5 renal injuries at 48 72 h. The aim of the current study is to evaluate the clinical utility of computed tomography (CT) reimaging in high-grade renal injuries. MATERIALS AND METHODS: We assembled data on 216 trauma patients with high-grade renal trauma at three level 1 trauma centers over a 19-year span between 1999 and 2017 in retrospectively collected trauma database. Demographic, radiographic, and clinical characteristics of patients were retrospectively reviewed. RESULTS: In total, 151 cases were Grade 4 renal injuries, and 65 were Grade 5 renal injuries. 53.6% (81) Grade 4 and 15.4% (10) Grade 5 renal injuries were initially managed conservatively. Of the 6 asymptomatic cases where repeat imaging resulted in intervention, 100% had collecting system injuries at initial imaging. Collecting system injuries were only present in 42.9% of cases where routine repeat imaging did not trigger surgical intervention. Collecting system injury at the time of initial imaging was a statistically significant predictor of routine repeat imaging triggering surgical intervention (p = 0.022). Trauma grade and the presence of vascular injury were not significant predictors of intervention after repeat imaging in asymptomatic patients. CONCLUSION: In asymptomatic patients with high-grade renal trauma, the number needed to image is approximately one in eight (12.5%) to identify need for surgical intervention. There is potentially room to improve criteria for routine renal imaging in high-grade renal trauma based on the more predictive imaging finding of collecting system injury. PMID- 30276542 TI - A comprehensive analysis of cost of an active surveillance cohort compared to radical prostatectomy as primary treatment for prostate cancer. AB - INTRODUCTION: Active surveillance (AS) seems to be a cost-effective strategy. However, most publications are based on simulation models of theoretical cohorts, and long-term implications are not usually considered. OBJECTIVE: To assess the real cost differences of two cohorts of men with low-risk prostate cancer (PCa) treated with AS or laparoscopic radical prostatectomy (LRP) in a public health system. MATERIALS AND METHODS: Patients diagnosed from 2005 to 2009 were included in an AS program (Group 1) or treated with LRP at diagnosis (Group 2), with a minimum follow-up of 5 years. Actual costs for each patient were calculated on an individual basis: Group 1: semiannual PSA measurements and repeat biopsies are scheduled every 1-3 years. Costs of outpatient clinic visits were calculated, as well as all tests required for monitoring or active treatment. Group 2: costs of the procedure, emergency visits, re-admissions and outpatient clinic visits were calculated, as well as costs of oncological salvage therapies or functional surgical procedures. RESULTS: Out of 151 men diagnosed with low-risk PC, 54 (35.8%) were included in an AS (Group 1) and 97 (64.2%) were submitted to LRP (Group 2). Mean follow-up for both groups was 6.5 years (SD 1.8) and 6.7 years (SD 1.4), respectively, p = 0.49. Group 1 had a total cost per patient of 2970.47?. Group 2 had a total cost per patient of 5694.06?. CONCLUSIONS: AS was associated with cost-saving over LRP. This cost reduction of AS in the management of low-risk PCa is based on the accounting of real costs of individual patients and confirms previously published estimation-based reports. PMID- 30276543 TI - The effect of androgen deprivation treatment on subsequent risk of bladder cancer diagnosis in male patients treated for prostate cancer. AB - INTRODUCTION: Bladder cancer (BCa) is three-to-four times more common in men than in women. To explain this gender gap, several theories have been proposed, including the impact of androgen hormones. The aim of this study was to investigate the differential impact of androgen deprivation therapy (ADT) on subsequent risk of developing BCa in men with prostate cancer (PCa). METHODS: A total of 196,914 patients diagnosed with histologically confirmed localized PCa between 2000 and 2009 were identified in the SEER-Medicare insurance program linked database. Competing-risk regression analyses were performed to assess the risk of developing BCa adjusting for the risk of all-cause mortality. Univariable and multivariable competing-risk regression analyses were performed to test the effect of ADT on BCa incidence for each PCa treatment modality. RESULTS: Of the 196,914 individuals included in the study, 68,421 (34.7%) received ADT. Median (IQR) follow-up was 59 (29-95) months. Overall, a total of 2495 (1.3%) individuals developed BCa during follow-up. After stratification according to ADT, the 10-year cumulative incidence rate was 1.75% (95% CI 1.65-1.85). In the untreated group, the 10-year cumulative incidence rate was 1.99% (95% CI 1.83 2.15). In multivariable competing-risk regression, the use of ADT was not associated with BCa, after accounting for the risk of dying from any cause (p = 0.1). CONCLUSION: We failed to identify any impact of ADT on the risk of developing a subsequent BCa even after stratifying according to the type of treatment. Further studies are required to explain the gender gap in BCa incidence and outcomes. PMID- 30276544 TI - Pharmacological management of post-traumatic seizures in adults: current practice patterns in the UK and the Republic of Ireland. AB - BACKGROUND: Patient selection for seizure prophylaxis after traumatic brain injury (TBI) and duration of anti-epileptic drug treatment for patients with early post-traumatic seizures (PTS), remain plagued with uncertainty. In early 2017, a collaborative group of neurosurgeons, neurologists, neurointensive care and rehabilitation medicine physicians was formed in the UK with the aim of assessing variability in current practice and gauging the degree of uncertainty to inform the design of future studies. Here we present the results of a survey of clinicians managing patients with TBI in the UK and Ireland. MATERIALS AND METHODS: An online survey was developed and piloted. Following approval by the Academic Committee of the Society of British Neurological Surgeons, it was distributed via appropriate electronic mailing lists. RESULTS: One hundred and seventeen respondents answered the questionnaire, predominantly neurosurgeons (76%) from 30 (of 32) trauma-receiving hospitals in the UK and Ireland. Fifty three percent of respondents do not routinely use seizure prophylaxis, but 38% prescribe prophylaxis for one week. Sixty percent feel there is uncertainty regarding the use of seizure prophylaxis, and 71% would participate in further research to address this question. Sixty-two percent of respondents use levetiracetam for treatment of seizures during the acute phase, and 42% continued for a total of 3 months. Overall, 90% were uncertain about the duration of treatment for seizures, and 78% would participate in further research to address this question. CONCLUSION: The survey results demonstrate the variation in practice and uncertainty in both described aspects of management of patients who have suffered a TBI. The majority of respondents would want to participate in future research to help try and address this critical issue, and this shows the importance and relevance of these two clinical questions.

PMID- 30276547 TI - Preclinical success but clinical failure of the sutureless excimer laser-assisted non-occlusive anastomosis (SELANA) slide. AB - BACKGROUND: The excimer laser-assisted non-occlusive anastomosis (ELANA) has been developed for intracranial bypass without the need for temporary recipient occlusion. We designed and tested a sutureless variant of the ELANA-the SELANA slide (SEsl). OBJECTIVE: This study aims to evaluate the SEsl preclinical results and describe its first clinical application. METHODS: First, in a cadaver study, 28 SEsl anastomoses were compared with 28 ELANA anastomoses. Second, in an acute rabbit model, 90 SEsl anastomoses were compared with 30 ELANA anastomoses. Finally, in a surviving pig model, 38 SEsl bypasses were created. To evaluate the clinical efficacy of the SEsl, we then treated one patient with a giant, right sided middle cerebral artery (MCA) aneurysm with an intracranial-intracranial SEsl bypass and parent vessel occlusion. RESULTS: In preclinical studies, the SEsl anastomosis was shown to be equivalent or superior to the ELANA in terms of associated ease, patency, and bleeding complications. However, clinical application in rigid and arteriosclerotic receiving arteries was problematic. Although bypass creation and aneurysm occlusion were technically successful and the patient was postoperatively well, a pseudoaneurysm formed postoperatively at the internal carotid artery anastomosis and bled. Subsequent treatment failed and the patient did not survive. CONCLUSION: The SEsl showed promising preclinical results across three models. However, in its present form, it is not suitable for clinical application. TRIAL NUMBER: IRB UMCU 10/154. PMID- 30276548 TI - Hydroxyapatite cranioplasty: a retrospective evaluation of osteointegration in 17 cases. AB - BACKGROUND: Cranial reconstruction with autologous bone is still the gold standard although several biomaterials are available to re-establish the integrity of the cranial vault. Due to their biological and morphological characteristics, hydroxyapatite implants show promising results in small clinical cohort studies, especially within the paediatric population. Its biocompatibility and osteoconductivity should allow the formation of osseous bridging at the skull prosthesis interface. OBJECTIVE: To examine the possible occurrence of osteointegration and to quantify it. METHODS: A retrospective study of patients with a hydroxyapatite implant from 2010 to 2014 at our neurosurgical department was conducted. Demographic, surgical and radiological data were studied. A senior neuroradiologist, a staff member neurosurgeon and a resident neurosurgeon independently performed the radiological evaluation. A new software analysis technique was developed to objectively quantify the degree of osteointegration. RESULTS: Seventeen implants were evaluated with an average patient age of 39 years and a mean follow-up of 155 weeks. Through radiologic evaluation, osseous bridging was deemed higher than 50% in six prostheses and higher than 75% in three. In five patients, no osteointegration could be seen. The remaining patients exhibited sparse signs of osteointegration, estimated between 10 and 50%. Software analysis showed an average osteointegration ratio of 37.4% with a 400-HU filter and 27.3% with a 700-HU filter. CONCLUSION: In this small retrospective study of cranial hydroxyapatite implants, osteointegration did occur and to a degree of more than 50% in 1/3 of the patients. PMID- 30276545 TI - Filling the gap between the OR and virtual simulation: a European study on a basic neurosurgical procedure. AB - BACKGROUND: Currently available simulators are supposed to allow young neurosurgeons to hone their technical skills in a safe environment, without causing any unnecessary harm to their patients caused by their inexperience. For this training method to be largely accepted in neurosurgery, it is necessary to prove simulation efficacy by means of large-scale clinical validation studies. METHODS: We correlated and analysed the performance at a simulator and the actual operative skills of different neurosurgeons (construct validity). We conducted a study involving 92 residents and attending neurosurgeons from different European Centres; each participant had to perform a virtual task, namely the placement of an external ventricular drain (EVD) at a neurosurgical simulator (ImmersiveTouch). The number of attempts needed to reach the ventricles and the accuracy in positioning the catheter were assessed. RESULTS: Data suggests a positive correlation between subjects who placed more EVDs in the previous year and those who get better scores at the simulator (p = .008) (fewer attempts and better surgical accuracy). The number of attempts to reach the ventricle was also analysed; senior residents needed fewer attempts (mean = 2.26; SD = 1.11) than junior residents (mean = 3.12; SD = 1.05) (p = .007) and staff neurosurgeons (mean = 2.89, SD = 1.23). Scoring results were compared by using the Fisher's test, for the analysis of the variances, and the Student's T test. Surprisingly, having a wider surgical experience overall does not correlate with the best performance at the simulator. CONCLUSION: The performance of an EVD placement on a simulator correlates with the density of the neurosurgical experience for that specific task performed in the OR, suggesting that simulators are able to differentiate neurosurgeons according to their surgical ability. Namely this suggests that the simulation performance reflects the surgeons' consistency in placing EVDs in the last year. PMID- 30276549 TI - Low-dose aspirin treatment enhances the adhesion of preeclamptic decidual mesenchymal stem/stromal cells and reduces their production of pro-inflammatory cytokines. AB - Preeclampsia (PE) is a hypertensive disorder of human pregnancy. Low-dose aspirin (acetylsalicylic acid) (60-150 mg/day) is used to prevent PE when taken early in pregnancy. The effect of aspirin on term PE remains uncertain. Abnormal placentation is a hallmark of PE and leads to increased placental oxidative stress, which triggers the release of anti-angiogenic factors that cause local damage to the decidual vasculature. The damage subsequently spreads systemically and culminates in maternal clinical symptoms. Decidua basalis mesenchymal stem/stromal cells (DMSCs) reside in a vascular microenvironment. In PE, DMSCs are exposed to abnormally high levels of oxidative stress and circulating inflammatory factors from the maternal blood. We previously showed that colony forming unit ability and resistance to oxidative stress in DMSCs are reduced in MSCs derived from term PE pregnancies (PE-DMSCs). The action, if any, of aspirin on term PE-DMSCs has not been reported. In this study, aspirin (5 MUg/mL) was found to significantly increase PE-DMSC adhesion compared to untreated PE-DMSCs and gestation-matched control DMSCs (p value < 0.001) but had no effect on PE DMSC proliferation. ELISA analysis showed that aspirin significantly decreased the production of inflammatory cytokines IFN-gamma (p value < 0.05) and IL-8 (p value < 0.001) in PE-DMSCs. In addition, aspirin treatment increased the antioxidant capacity of PE-DMSCs compared with the untreated group (p value < 0.05). This study is the first to reveal a novel, beneficial action of aspirin on PE-DMSCs from term PE pregnancies by improving their adhesion, suppressing their production of pro-inflammatory cytokines production, and increasing their antioxidant capacity. KEY MESSAGES: Preeclampsia (PE) is a serious hypertensive disorder of pregnancy. The risk of PE is reduced by aspirin but the mechanism is poorly understood. Decidua basalis mesenchymal stem/stromal cells (DMSCs) are abnormal in PE. Aspirin treatment improves multiple functions of PE-DMSCs. Improved DMSC function may contribute to the beneficial effect of aspirin. PMID- 30276550 TI - A fluorometric aptasensor for patulin based on the use of magnetized graphene oxide and DNase I-assisted target recycling amplification. AB - A fluorometric patulin (PAT) assay is presented that is based on the use of magnetic reduced graphene oxide (rGO) and DNase I. The fluorescence of the PAT aptamer labelled with 6-carboxyfluorescein (FAM) is quenched by magnetized reduced graphene oxide (rGO-Fe3O4) due to fluorescence resonance energy transfer (FRET). However, in the presence of PAT, the labelled aptamer is stripped off from rGO-Fe3O4. The rGO-Fe3O4 is then magnetically separated so that the fluorescence of free labelled PAT aptamer is restored. DNase I cannot hydrolyze the aptamer on rGO-Fe3O4, but it can cleave the free aptamer-PAT complex. This will release FAM and PAT which can undergo a number of additional cycles to trigger the cleavage of abundant aptamer. Recycling of DNase I-assisted target therefore leads to a strong amplification of fluorescence and consequently to an assay with low limit of detection. The detection limit for PAT is as low as 0.28 MUg L-1 which is about 13 times lower than that without using DNase I. The method offers a new approach towards rapid, sensitive and selective detection based on an aptamer. Conceivably, it has a wide scope in that it may be applied to numerous other analytes if appropriate aptamers are available. Abstract Schematic of a fluorometric assay based on the use of magnetic graphene oxide and DNase I. It was applied to the determination of patulin. DNase I was introduced for recycling amplification. The detection limit is about 13 times lower than that without using DNase I. Figure a contains poor quality of text in image. Otherwise, please provide replacement figure file.Thank you.

AB - PURPOSE: The presence of M2 macrophages within primary tumors has been correlated with a poor prognosis for many types of cancer. However, little is known about the role of M2 macrophages in gallbladder cancer (GBC). METHODS: The number of M2 macrophages in 78 GBC and 16 normal gallbladder tissue samples was assessed by immunohistochemistry. The THP-1 monocyte cell line was differentiated into M2 macrophages and co-cultured with GBC-derived cell lines. The effect of M2 macrophages on promoting GBC cell migration and invasion was analyzed using migration, invasion and scratch wound healing assays. Western blotting and real time PCR were used to assess the expression of epithelial-mesenchymal transition (EMT) markers and the activation status of the PI3K/Akt signaling pathway in GBC cells co-cultured with THP-1-derived macrophages. RESULTS: The average number of M2 macrophages was found to be significantly higher in GBC tissues than in normal gallbladder tissues. We also found that GBC patients with higher M2 macrophage counts exhibited poorer overall survival rates. Co-culture with M2 macrophages significantly promoted the migration, invasion and EMT of GBC cells. Moreover, we found that CCL18 secreted from M2 macrophages had the same effect on GBC cells as M2 macrophages. Blocking the function of CCL18 with a neutralizing antibody reversed this effect. Finally, we found that M2 macrophages could activate PI3K/Akt signaling in GBC cells, thereby leading to migration, invasion and EMT of these cells. CONCLUSIONS: Our findings contribute to our understanding of the role of chronic inflammation in GBC development and progression, and may offer potential therapeutic targets for GBC. PMID- 30276552 TI - Berberine attenuate staphylococcal enterotoxin B-mediated acute liver injury via regulating HDAC expression. AB - Staphylococcal enterotoxin B (SEB) has been documented to be implicated in the pathogenesis of liver injury in the experimental models of hepatitis. However, the underlying mechanism of SEB-induced acute liver injury (ALI) remains to be further explored. In our study, we explored the therapeutic effectiveness of berberine (BBR), a natural isoquinoline alkaloid, in the SEB-induced ALI. In our study, we found that injection of SEB into D-galactosamine (D-gal)-sensitized mice induced ALI, as demonstrated by an increase of levels of alanine aminotransferase and aspartate aminotransferase, massive infiltration of immune cells into the liver, and pro-inflammatory cytokine release. However, intragastric administration of BBR attenuated SEB-induced ALI in mice. Meanwhile, we discovered that BBR treatment suppressed activation of splenocytes and pro inflammatory cytokine release in SEB-stimulated splenocytes. Moreover, mechanistic analyses demonstrated that BBR was effective at inhibiting the expression of class I HDAC, but not class II, in SEB-stimulated splenocytes. Furthermore, trichostatin A, a standard HDAC inhibitor, alleviated activation of splenocytes and pro-inflammatory cytokine release in SEB-stimulated splenocytes. Taken together, we inferred from these results that BBR attenuated SEB-mediated ALI through repressing the class I HDAC enzyme, suggesting that BBR may constitute a novel therapeutic modality to prevent SEB-mediated inflammation and ALI. PMID- 30276553 TI - Bergenin: a computationally proven promising scaffold for novel galectin-3 inhibitors. AB - Bergenin is a C-glycoside of 4-O-methylgallic acid that is isolated from medicinal plants such as Flueggea leucopyrus, Bergenia crassifolia, Mallotus philippensis, Corylopsis spicata, Caesalpinia digyna, Mallotus japonicus, and Sacoglottis gabonensis. Even though there appears to be ample evidence from South Asian traditional medicine that bergenin possesses strong anticancer activity, no comprehensive scientific study has been carried out to test its anticancer potency. Therefore, in this study, the potential mechanisms of action for bergenin's postulated anticancer activity were examined using computational techniques. Firstly, bergenin was tested for its toxicity as a drug candidate using in silico toxicity analysis. It was found that bergenin is nontoxic according to modern toxicity measures. The optimized structure of bergenin was obtained at the DFT-B3LYP/6-31G(d) level of theory. Potential biological targets of bergenin were identified using reverse docking calculations. Reverse docking results suggested that galectin-3 is a potential target of bergenin. Gelectin-3 is an enzyme that plays a major role in cell-cell adhesion, cell-matrix interactions, macrophage activation, angiogenesis, metastasis, and apoptosis in cancer, making it a popular target in anticancer drug design. Among the many potential biological targets predicted by reverse docking calculations, galectin 3 was selected as it complies with the primary objective of this study. The binding of bergenin to galectin-3 was studied by conventional forward docking calculations. Classical molecular dynamics (MD) simulations were used to study the stability of the galectin-3:bergenin complex. Docking calculations indicated that bergenin has the potential to effectively bind to the carbohydrate recognition domain (CRD) of galectin-3. As well as electrostatic and van der Waals interactions, a few strong hydrogen bonds were found to be involved in the binding of bergenin to galectin-3. There is also a plausible pi-stacking interaction between the aromatic moiety of bergenin and the His158 residue at the binding site. A 50-ns MD simulation was carried out for the bergenin:galectin-3 complex in a cubic water box with periodic boundary conditions. The MD results showed that the bergenin:galectin-3 complex is highly stable and confirmed the veracity of the docking results, which suggested that bergenin potentially exerts an inhibitory effect on galectin-3. This study therefore sheds new light on the anticancer activity of bergenin and demonstrates that bergenin could potentially be used to develop more potent galectin-3 inhibitors. The study also provides scientific evidence supporting the use of bergenin-containing plants in cancer treatments in Eastern traditional medicine.

PMID- 30276554 TI - Molecular Testing in EBUS-TBNA Specimens of Lung Adenocarcinoma: A Study of Concordance Between Cell Block Method and Liquid-Based Cytology in Appraising Sample Cellularity and EGFR Mutations. AB - PURPOSE: Cytological endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) specimens of mediastinal lymph node metastasis are frequently used to perform concomitant diagnosis, staging and genetic testing in non-small-cell lung cancer (NSCLC). The purposes of this single-center retrospective study were to evaluate EBUS-TBNA samples' adequacy for molecular testing of epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK), and to analyze the concordance between the cell block method and liquid based cytology (LBC) in appraising the sample cellularity and in detecting EGFR mutation. MATERIALS AND METHODS: We retrospectively examined 82 patients who underwent EBUS-TBNA from October 2012 to September 2015 and received a confirmed diagnosis of lymph node metastasis of lung adenocarcinoma. Each sample was processed using both cell block and LBC to carry out DNA analysis (adequacy criterion: tumor cell percentage > 25%) and EGFR mutation testing. RESULTS: Fifty four patients were male, 66 were current or former-smokers, and the median age was 67 years. The median size of sampled lymph nodes was 14.8 mm. Seventy-one and 66 samples were adequate to perform cell block and LBC, respectively. The kappa statistic (0.78) showed an excellent concordance. EGFR mutation was detected in eight patients using cell block and in seven using LBC, with a simple percentage agreement of 87.5%. ALK translocation was found in two patients. CONCLUSIONS: This study demonstrates the feasibility of EGFR mutation analysis with both cell block and LBC, with an excellent concordance between the two methods. Considering that the majority of advanced NSCLCs are diagnosed on cytology specimens, LBC is feasible and needs to be implemented for ancillary tests (immunocytochemistry, molecular analysis). PMID- 30276555 TI - Signal Detection Between Fluoroquinolone Use and the Risk of Rhegmatogenous Retinal Detachment: Sequence Symmetry Analysis Using Nationwide South Korean Healthcare Database Between 2004 and 2015. AB - BACKGROUND AND OBJECTIVES: The association between fluoroquinolone and rhegmatogenous retinal detachment (RRD) has been controversial as a result of inconsistent findings. We set out to detect a possible association of fluoroquinolone use and risk of RRD, using sequence symmetry analysis (SSA). METHODS: We conducted an SSA, case-only design, using a Korean nationwide healthcare database between 2004 and 2015. Exposure was defined as new fluoroquinolone use and outcome as an incident RRD, defined by a diagnosis of RRD (ICD-10: "H33.0") or surgery for RRD. Pairs of exposure and RRD within a 1-year time-window were included. The sequence ratio (SR) was calculated by the ratio of the number of patients prescribed with exposure first and diagnosed with RRD second divided by the number of patients diagnosed with RRD first and prescribed with exposure second. SR was adjusted (aSR) for underlying trends and 95% confidence intervals (CIs) were calculated. In order to observe whether the estimated ratio stabilized over time, we did repeated time-sequential analyses with the cumulative data starting from the 3-year period 2004-2006 to 2015. RESULTS: Fluoroquinolone use had a greater association with RRD as compared with other antibiotics [fluoroquinolone: 5234 pairs; aSR = 1.70 (95% CI 1.61-1.80), first-generation cephalosporin: 4139 pairs; aSR = 1.39 (95% CI 1.31-1.80), second generation cephalosporin: 5914 pairs; aSR = 1.31 (95% CI 1.24-1.38), third generation cephalosporin: 3650 pairs; aSR = 0.88 (95% CI 0.83-0.95), extended spectrum penicillin: 4823 pairs; aSR = 1.29 (95% CI 1.31-1.47), macrolides: 4115 pairs; aSR = 1.31 (95% CI 1.24-1.39)]. Time-sequential analyses supported the association between fluoroquinolone and RRD. CONCLUSIONS: Our detection suggests a possible association between fluoroquinolone use and RRD. However, possible overestimation and reverse causality bias may have influenced our findings due to the limitation of an SSA design. PMID- 30276557 TI - A Nanometer Water Pump Induced by the Brownian and Non-Brownian Motion of a Graphene Sheet on a Membrane Surface. AB - Energy-saving water pump and efficient semipermeable membranes are the cores of reverse osmosis technology. Applying nanotechnology to improve the performance is a fashion in recent years. Based on the competitive effect of water's spontaneous infiltration of two sides of a carbon nanotube, we design a water pump that makes use of the natural permeability by weakening one side's competitiveness based on a small graphite sheet laying on the membrane. According to molecular dynamic simulations, continues net flux is observed. The motion mode of the sheet is the key for the performance. For the pure Brownian motion without any dynamical load, we find two water molecules per nanosecond flux, while the flux induced by the unidirectional motion can be several times enhanced, depending on the external force. The Brownian motion is similar to the physical mechanism of osmotic pressure, and the unidirectional motion shows great performance that has huge applications for reverse osmosis. Our work creatively proposes a new strategy to pump water molecules crossing though a nanochannel, inspiring for nanofluidic device designers. PMID- 30276558 TI - Luteolin suppresses inflammation through inhibiting cAMP-phosphodiesterases activity and expression of adhesion molecules in microvascular endothelial cells. AB - Luteolin, an anti-inflammatory ingredient found in the Chinese herb Folium perillae, can inhibit not only the cyclic adenosine monophosphate (cAMP) phosphodiesterases (PDEs) activity of neutrophils, but also the expression of lymphocyte function-associated antigen-1 in neutrophils, both of which result in a decrease in the adhesion between neutrophils and microvascular endothelial cells. However, the effect of luteolin on the cAMP-PDEs activity and expression of adhesion molecules in endothelial cells are not clear. In the present study, primary rat pulmonary microvascular endothelial cells and a lipopolysaccharide induced rat acute pneumonia model were used to explore the role of luteolin on cAMP-PDEs activity, expression of adhesion molecules, and leukocyte infiltration. We demonstrate that rat pulmonary microvascular endothelial cells expressed high levels of cAMP-PDEs, specifically PDE4, and further luteolin exhibited dose dependent inhibition on the activity of cAMP-PDEs or PDE4 in endothelial cells. Luteolin also had a significant inhibitory effect on the expression of vascular cell adhesion molecule (VCAM)-1, but not intracellular cell adhesion molecule (ICAM)-1 in microvascular endothelial cells. Further, we show that luteolin decreased the levels of soluble ICAM-1 (sICAM-1), but not soluble E-selectin in the serum of rats subjected to acute pneumonia. We also show that luteolin treatment decreased the wet/dry weight ratio of lung tissue and reduced the total number of serum leukocytes in a dose-dependent manner in a rat acute pneumonia model. In conclusion, these results demonstrate that luteolin suppresses inflammation, at least in part, through inhibiting both cAMP-PDEs or PDE4 activity and the expression of VCAM-1 (in vitro) and sICAM-1 (in vivo) in endothelial cells. PMID- 30276556 TI - Improved bioethanol production using CRISPR/Cas9 to disrupt the ADH2 gene in Saccharomyces cerevisiae. AB - Bioethanol, as a form of renewable and clean energy, has become increasingly important to the energy supply. One major obstacle in ethanol production is developing a high-capacity system. Existing approaches for regulating the ethanol production pathway are relatively insufficient, with nonspecific genetic manipulation. Here, we used CRISPR/Cas9 technology to disrupt the alcohol dehydrogenase (ADH) 2 gene via complete deletion of the gene and introduction of a frameshift mutation in the ADH2 locus. Sequencing demonstrated the accurate knockout of the target gene with 91.4% and near 100% targeting efficiency. We also utilized genome resequencing to validate the mutations in the ADH2 mutants targeted by various single-guide RNAs. This extensive analysis indicated the mutations in the CRISPR/Cas9-engineered strains were homozygous. We applied the engineered Saccharomyces cerevisiae strains for bioethanol production. Results showed that the ethanol yield improved by up to 74.7% compared with the yield obtained using the native strain. This work illustrates the applicability of this highly efficient and specific genome engineering approach to promote the improvement of bioethanol production in S. cerevisiae via metabolic engineering. Importantly, this study is the first report of the disruption of a target gene, ADH2, in S. cerevisiae using CRISPR/Cas9 technology to improve bioethanol yield. PMID- 30276560 TI - Long-term clinical, radiological, and histological follow-up after complex ventral incisional hernia repair using urinary bladder matrix graft reinforcement: a retrospective cohort study. AB - BACKGROUND: Complex ventral incisional hernia repair represents a challenging clinical condition in which biologically derived graft reinforcement is often utilized, but little long-term data inform that decision. Urinary bladder matrix (UBM) has shown effectiveness in diverse clinical settings as durable reinforcement graft material, but it has not been studied over a long term in ventral incisional hernia repair. This study evaluates the clinical, radiographic, and histological outcome of complex incisional hernia repair using UBM reinforcement with 12-70 months of follow-up. METHODS: A single-arm, retrospective observational study of all ventral incisional hernia repairs utilizing UBM reinforcement over a 6-year time frame by a single surgeon was performed. Patients were assessed in long-term follow-up clinically and with the Carolina Comfort Scale. A subset of patients was assessed with abdominal wall ultrasound or CT scan. Three patients had abdominal wall fascial biopsies years after the incisional hernia repair with UBM graft, and the histology is analyzed. RESULTS: 64 patients underwent repair of complex incisional hernias with UBM graft reinforcement by a single surgeon. 42 patients had concomitant procedures including large or small bowel resection, excision of infected mesh, evacuation of abscess or hematoma, cholecystectomy, or panniculectomy with abdominoplasty. 16 patients had ostomies at the time of repair. Median follow-up time is 36 months, with a range of 12-70 months. Nine patients (14%) have required surgical repair of a recurrent hernia, and a tenth patient has a recurrence that is managed non-surgically, for a total recurrence rate of 15.6% over the entire time frame. Median time to recurrence was 32 months, and a Kaplan-Meier freedom from recurrence curve is depicted. 28 patients have undergone ultrasound or CT assessments of the abdominal wall which demonstrate radiographic fascial integrity 12-70 months after repair. Three patients have been re-explored for unrelated reasons in the years following ventral incisional hernia repair with UBM, and full thickness fascial biopsies demonstrate a robust remodeling response histologically similar to native myofascial tissue. No patients have developed graft infection, fistulization to the graft, or required graft explantation. Carolina Comfort Scale assessment of 45 patients 3 years after the repair averaged 16 out of a possible 115. CONCLUSION: In 64 patients undergoing complex ventral incisional hernia repair with UBM reinforcement, all have experienced successful resolution of complex clinical conditions and 15.6% of these repairs have recurred at a median follow-up of 3 years. Three full-thickness biopsies of the repaired fascia years later shed light on a promising remodeling response which may signal strength and durability comparable to native fascia. PMID- 30276559 TI - Increased Sputum IL-17A Level in Non-asthmatic Eosinophilic Bronchitis. AB - BACKGROUND: Non-asthmatic eosinophilic bronchitis (NAEB) is one common cause of chronic cough which is characterized as airway eosinophilic inflammation like asthma but lack of airway hyper-responsiveness. Previous studies showed that Th2 pathway plays a role in NAEB, but the role of non-Th2 pathway in mechanism of NAEB remains unknown. Recently, IL-17A, a Th17-pathway cytokine, has been demonstrated to be involved in asthma development. However, the relationship between Th17-pathway and NAEB is unknown. METHODS: We aim to assess the airway level of IL-17A in the subjects with NAEB. Relationships between the IL-17A level and airway function in NAEB or asthma are also observed. We measured IL-17A concentrations in the sputum supernatant from 12 subjects with EB, 16 subjects with asthma [9 eosinophilic asthmatic (EA) and 7 non-eosinophilic asthmatic (NEA) according to the sputum eosinophil >= 3%], and 9 healthy control subjects. RESULTS: Increasing IL-17A level was found in NAEB group (29.65 +/- 8.13 pg/ml), EA group (32.45 +/- 3.22 pg/ml), and NEA group (29.62 +/- 6.91 pg/ml) compared with the healthy control group (17.05 +/- 10.30 pg/ml) (P < 0.05, P < 0.01, P < 0.05, respectively). The sputum IL-17A level was correlated with FENO (r = 0.44, P < 0.01), FEV1/FVC% (r = - 0.38, P < 0.05), MMEF%pred (r = - 0.34, P < 0.05), and sputum neutrophil% (r = 0.33, P < 0.05) in total. CONCLUSION: Th17-pathway may play a role not only in asthmatics, but also in subjects with NAEB, as reflected by increasing IL-17A concentrations in sputum supernatant. PMID- 30276562 TI - The role of personality in patients with fibromyalgia. AB - Previous studies suggest personality, the multifaceted characteristics underlying a person's affect, cognition, and behavior, may influence fibromyalgia. We examined associations among personality, fibromyalgia impact, and health-related outcomes in patients with fibromyalgia. We further tested whether anxiety and depression mediated the effect of personality on fibromyalgia impact. We performed a secondary analysis using baseline data from a randomized trial on fibromyalgia. Personality was assessed using the NEO-Five Factor Inventory 3. Fibromyalgia impact was evaluated using the revised Fibromyalgia Impact Questionnaire (FIQR). We also measured symptom severity, anxiety, depression, stress, quality of life, social support, self-efficacy, outcome expectations, and mindfulness. Multivariable linear regression was performed to evaluate each association. Mediation analysis assessed whether anxiety and depression mediated the relationship between personality and FIQR. There were 92 participants, 95% female, mean age 52 years, body mass index (BMI) 30 kg/m2, 52% white, and mean duration of body pain 14 years. Higher neuroticism was significantly associated with higher FIQR (P = 0.002) and symptom severity (P = 0.008), as well as higher levels of anxiety, depression and stress, worse mental component quality of life, and lower self-efficacy, mindfulness, and social support. Higher conscientiousness and extraversion were associated with better psychological health and health-related outcomes. The effect of neuroticism on fibromyalgia impact was mediated by anxiety and depression. Personality was associated with fibromyalgia impact and a variety of health outcomes. Identifying the factors that influence fibromyalgia will help us better understand the condition and provide insight for more effective treatment. PMID- 30276561 TI - Surgical site infection: the "Achilles Heel" of all types of abdominal wall hernia reconstruction. AB - PURPOSE: Surgical site infection is the most common hospital-acquired infection in surgical patients. Recently, public health organizations have updated prevention guidelines. This review discusses surgical site infections as a complication of abdominal wall reconstruction. METHODS: The authors reviewed guidelines on prevention of surgical site infections from the Center for Disease Control and Prevention, World Health Organization, and National Institute for Health and Care Excellence and put them into context with the relevant abdominal wall reconstruction literature. This was the subject of the Nyhus-Wantz lecture given at The International Hernia Congress on March 14, 2018 in Miami, FL and is summarized here. RESULTS: Routine use of preoperative antibiotics in prosthetic groin hernia repair is not supported by the available literature. High-quality data on antibiotic prophylaxis in ventral (both primary and incisional) hernia repair is lacking, but it is widely utilized and may reduce SSIs. Recommended preventative strategies discussed in this manuscript include: treatment of remote site infections, perioperative normothermia and normoglycemia, avoidance of hypoxemia, antiseptic preparation of surgical team hands and patient skin, treatment of obesity, smoking cessation, correction of malnutrition, and physical conditioning. CONCLUSION: Surgical site infections lead to significant morbidity and mortality, hernia recurrences, prolonged hospital stay, and increased hospital costs. This makes surgical site infections the "Achilles Heel" of abdominal wall reconstruction. Strict adherence to standardized guidelines and preoperative optimization of patients' risk profiles are crucial to decrease the incidence of surgical site infections.

AB - BACKGROUND: For 4 years, the profession of critical care paramedic has been established in Germany. As a result, nonmedical rescue service personnel receive a 3-year apprenticeship for the first time. This also led to a revaluation of functions and responsibilities within this occupational field. OBJECTIVES: Which medical and social processes contributed to the establishment of the occupational profile of a critical care paramedic? How did training methods change over the last 50 years and which debates helped to shape the development of the occupational field? MATERIALS AND METHODS: The article at hand is based on an interpretation of archival primary sources of the parties observed. Moreover, it is also predicated on a qualitative content analyses of the secondary literature focusing on the subject area of nonmedical rescue service personnel. RESULTS: In the 1960s, a professionalisation process for paramedics was initiated after realising that rapid medical treatment on location can have a positive impact on the healing process. The debate on the training for paramedics has been influenced by longstanding negotiations between different parties about the question of which tasks could be ascribed to nonmedical rescue service personnel. CONCLUSIONS: In the larger context, the discussions about the tasks of critical care paramedics are centered around the question of delegation and, respectively, the substitution of medical tasks usually assigned to physicians. The academization of the profession that is currently emerging will continue to lead to conflicts with the medical profession. PMID- 30276563 TI - Severe thrombocytopenia in connective tissue diseases: a single-center review of 131 cases. AB - To analyze the clinical characteristics of severe thrombocytopenia in patients with various connective tissue diseases (CTDs), one hundred thirty-one consecutive CTD patients with blood platelet count less than 20 * 109/L on admission, which was ascribed to the nature of diseases, during January 2011 to June 2015 in our department were enrolled and checked for their survival status in September 2015. The patients were categorized based on background diseases or therapeutic effects, and compared with clinical features, treatment strategies, and long-term outcomes among the groups. Cumulative survival rates were estimated using Kaplan-Meier analysis. Of the patients, 88.5% were female. The most frequently seen background diseases were primary Sjogren's syndrome (pSS) (53.4%) and systemic lupus erythematosus (SLE) (40.5%). Age on admission for SLE patients (36.7 +/- 14.1 years) was much younger than that for other patients (44.4 +/- 15.4 years for pSS and 46 +/- 16.1 years for other CTDs, p < 0.05). Ninety-six cases accompanied with various bleeding symptoms, which were more common in pSS patients than in SLE patients (80.0% vs. 64.2%, p < 0.05). Glucocorticoids and/or intravenous immunoglobulin were applied as initial therapy with an overall response rate of 36.6%. For patients failed to respond, immunosuppressive drugs were added and the other 22.8% benefited from the treatment. Compared to those ineffective to the aforementioned drugs, patients with therapeutic effects had significantly high immunoglobulin G levels. Twenty patients with refractory diseases accepted mesenchymal stem cell transplantation (MSCT) with a total effective rate of 65.0%. Eleven patients died after the follow-up for a mean time of 27.7 months, of which 7 were associated with hemorrhage. There was no difference in the survival rate among different background diseases. However, compared with those who did not gain remission, patients achieved partial or complete remission had better cumulative survival rates (p < 0.01). In conclusion, among various CTDs, severe thrombocytopenia often occurs in patients with SLE or pSS. Early response to the treatments, but not the background disease, is an important predictor of long-term prognosis. For patients with refractory thrombocytopenia, MSCT may provide an alternative therapeutic strategy.

AB - INTRODUCTION: The SOFA (Sequential Organ Failure Assessment), GCS (Glasgow Coma Scale), and FOUR (Full Outline of UnResponsiveness) scores are the most commonly used scoring systems to predict the risk of mortality and morbidity in intensive care units (ICUs). The aim of the current study was to compare the predictive ability of these three models for predicting medical/surgical ICU mortality in critically ill children. METHODS: In the current observational and prospective study, a total of 90 consecutive patients, age <=18 years, admitted to medical and surgical ICUs, were enrolled. The SOFA, GCS, FOUR score and demographic characteristics of all children were recorded on the first day of admission. For statistical analyses, a receiver operator characteristic (ROC) curve, the Hosmer Lemeshow goodness of fit test, and logistic regression were used (95% confidence interval). RESULTS: The SOFA, GCS, and FOUR scores between survivors and nonsurvivors were statistically different (p = 0.002, p < 0.001, p = 0.004, respectively). The discrimination power for SOFA, GCS, and FOUR score was moderate (area under ROC [AUC] curve: 75.1%; standard error [SE]: 6.0%, 72.9% [SE: 7.2%], 78.7% [SE: 6.6%], respectively). The only well-calibrated model was GCS (x2 = 2.76, p = 0.59). CONCLUSIONS: The performance of the three predictive models SOFA, GCS, and FOUR score for predicting outcomes in children admitted to medical and surgical ICUs was good. The discrimination was moderate for all three models, and calibration was good just for GCS. GCS was superior in predicting outcome in critically ill children; however, further studies are needed to validate these scores in the pediatric population. PMID- 30276566 TI - [Multidrug-resistant bacteria in animals and humans]. AB - BACKGROUND: The increasing burden of antimicrobial-resistant bacteria causes morbidity and mortality, especially among patients affected by healthcare associated infections. Limited treatment options challenge clinicians in both human and veterinary medicine. OBJECTIVES: To summarize current evidence for the occurrence of antimicrobial-resistant bacteria and their zoonotic transmission between humans and animals with a focus on data from Germany. MATERIALS AND METHODS: Review of scientific literature and publications from German national public health institutions. RESULTS AND CONCLUSIONS: Methicillin-resistant Staphylococcus aureus (MRSA) and extended-spectrum beta-lactamase (ESBL) producing Enterobacteriaceae are frequently transmitted between animals and humans. The rates of asymptomatic carriage are increased among persons with livestock contact compared with the general population. The occurrence of carbapenemase-producing Enterobacteriaceae has been documented on German pig and chicken farms, but investigations into their prevalence and zoonotic importance are pending. Colistin is frequently used in veterinary medicine to treat diarrhoea and causes selection pressure for colistin-resistant Gram-negative bacteria harbouring mcr genes. Vancomycin-resistant enterococci (VRE), oxazolidinone-resistant Gram-positive bacteria and multiresistant staphylococci are further antimicrobial-resistant microorganisms, which might have a zoonotic potential. Besides human healthcare and livestock, the problem of antimicrobial resistant bacteria also affects companion animals (e. g. dogs, cats and horses), wildlife and the environment, which underlines the need to prevent antimicrobial resistance in a One Health approach.

PMID- 30276568 TI - Creeping Fat Assessed by Small Bowel MRI Is Linked to Bowel Damage and Abdominal Surgery in Crohn's Disease. AB - BACKGROUND: Crohn's disease (CD) leads to bowel damage and surgery in a significant proportion of patients. AIMS: The aim of the study was to evaluate the predictive value of creeping fat assessed by small bowel MRI in CD patients. METHODS: CD patients undergoing small bowel MRI were included in a retrospective observational cohort study. Clinical findings were extracted and correlated with radiological outcome measures. Logistic regression analysis was performed to assess predictors associated with a complicated course and surgery within 2 years and long-term follow-up. RESULTS: Ninety patients (49% female, median follow-up 93 months) were included. Creeping fat was identified in 21.1%. Of these patients, 68% and 79% developed bowel damage (p < .05) and 42% and 63% of patients revealing creeping fat underwent surgery within 2 years following MRI and total follow-up, respectively. The presence of creeping fat [odds ratio (OR) 4.0], inflammatory stenosis (OR 3.7), multisegmental (small) bowel (OR 4.5 and 3.8), and proximal small bowel inflammation (OR 5.0) were associated with inferior outcome (p < .05) in a univariate analysis. Creeping fat was independently associated with a disabling course, bowel damage, and surgery (OR 3.5 each, p < .05) in a multivariate analysis model. CONCLUSION: Creeping fat identified by small bowel MRI is associated with a complicated course and abdominal surgery in CD. Our data adds evidence that small bowel MRI facilitates risk stratification in order to define a patient at risk of disease-related complications in CD. [DRKS00011727, www.germanctr.de/ ]. PMID- 30276569 TI - Sodium Butyrate Enhances Intestinal Riboflavin Uptake via Induction of Expression of Riboflavin Transporter-3 (RFVT3). AB - BACKGROUND: Uptake of riboflavin (RF) by intestinal epithelial cells occurs via a specific carrier-mediated process that involves the apically localized RF transporter-3 (RFVT3). Previous studies have shown that sodium butyrate (NaB) affects intestinal uptake of other substrates and expression of their membrane transporters, but its effect on intestinal uptake of RF and expression of RFVT3 has not been examined. AIMS: To investigate the effect of NaB on intestinal RF uptake process and expression of the RFVT3. METHODS: Two experimental models were used in this study: Human-derived intestinal epithelial Caco-2 cells and ex vivo mouse colonoids. 3H-RF uptake assay, Western blot, RT-qPCR, and chromatin immunoprecipitation assay were performed. RESULTS: Treating Caco-2 cells with NaB led to a significant increase in carrier-mediated RF uptake. This increase was associated with a significant induction in the level of expression of the hRFVT3 protein, mRNA, and heterogenous nuclear RNA (hnRNA). Similarly, treating mouse colonoids with NaB led to a marked increase in the level of expression of the mRFVT3 protein, mRNA, and hnRNA. NaB did not affect hRFVT3 mRNA stability, rather it caused significant epigenetic changes (histone modifications) in the SLC52A3 gene where an increase in H3Ac and a reduction in H3K27me3 levels were observed in the NaB-treated Caco-2 cells compared to untreated controls. CONCLUSION: These findings demonstrate that NaB up-regulates intestinal RF uptake and that the effect appears to be mediated, at least in part, at the level of transcription of the SLC52A3 gene and may involve epigenetic mechanism(s). PMID- 30276570 TI - Differences in Prevalence of Large Polyps Between Hispanic Americans from Mexican and Non-Mexican-Predominant States. AB - BACKGROUND: There have been conflicting reports comparing the prevalence of large polyps (>9 mm) between Hispanics and non-Hispanic whites (NHW). Differences between Hispanic subpopulations may account for these variations. AIMS: We aimed to assess the prevalence of large polyps (>9 mm) in Hispanics from Mexican- and non-Mexican-predominant states compared with NHW. As secondary outcome, we evaluated results by polyp location. METHODS: The 2010 U.S. Census Bureau was used to identify states with a predominantly Mexican Hispanic (West) versus non Mexican Hispanic (East) populations. Average-risk colonoscopies in those states from 2001 to 2014 were accessed using the Clinical Outcomes Research Initiative database. Military and Veteran's Administration sites were excluded. Hispanics were compared with NHW in each geographical location using hierarchical logistic regression analysis. RESULTS: A total of 65,138 procedures were included with 33,425 procedures in the West (14.5% Hispanics) and 31,713 procedures in the East (44.0% Hispanics,). East Hispanics had significantly less odds of large polyps, OR 0.74, CI 0.58-0.94, p = 0.02, while West Hispanics exhibited no difference, OR 0.91, CI 0.76-1.10, p = 0.33, compared with NHW. Eastern Hispanics had less odds of large distal polyps, OR 0.69, CI 0.52-0.91, p = 0.01, and no difference in proximal polyps compared with NHW. Among Western Hispanics, no differences were seen in proximal, OR 1.06, CI 0.83-1.35, p = 0.66, or distal polyps, OR 0.83, CI 0.68-1.02, p = 0.08, compared with NHW. CONCLUSION: Using NHW as a reference, Hispanics from Mexican-predominant states have a similar prevalence of large polyps, while Hispanics from non-Mexican-predominant states have a lower prevalence. Differences in Hispanic subpopulations likely explain previous conflicting reports on the prevalence of large polyps in Hispanics and NHW. PMID- 30276573 TI - The inhibition of thymidine phosphorylase can reverse acquired 5FU-resistance in gastric cancer cells. AB - BACKGROUND: 5FU can be converted to its active metabolite fluoro-deoxyuridine monophosphate (FdUMP) through two pathways: the orotate phosphoribosyl transferase-ribonucleotide reductase (OPRT-RR) pathway and the thymidine phosphorylase-thymidine kinase (TP-TK) pathway. We investigated the mechanism underlying 5FU-resistance, focusing on the changes in the 5FU metabolisms. METHODS: MKN45 and 5FU-resistant MKN45/F2R cells were treated with 5FU or fluoro deoxyuridine (FdU) in combination with hydroxyurea (HU) or tipiracil (TPI). The amount of FdUMP was determined by the density of the upper band of thymidylate synthase on Western blotting. RESULTS: The MKN45/F2R cells exhibited 5FU resistance (37.1-fold) and showed decreased OPRT and increased TP levels. In both cells, the FdUMP after treatment with 5FU was decreased when RR was inhibited by HU but not when TP was inhibited by TPI. A metabolome analysis revealed the loss of intracellular deoxyribose 1-phosphate (dR1P) in both cells, indicating that FdUMP was synthesized from 5FU only through the OPRT-RR pathway because of the loss of dR1P. After the knockdown of TK, the FdUMP after treatment with FdU was decreased in MKN45 cells. However, it was not changed in MKN45/F2R cells. Furthermore, TP inhibition caused an increase in FdUMP after treatment with 5FU or FdU and reversed the 5FU resistance in MKN45/F2R cells, indicating that FdUMP was reduced through the TP-TK pathway in MKN45/F2R cells. CONCLUSIONS: In MKN45/F2R cells, the reduction of FdUMP through the TP-TK pathway caused 5FU resistance, and the inhibition of TP reversed the resistance to 5FU, suggesting that the combination of 5FU and TPI is a promising cancer therapy. PMID- 30276571 TI - Utility of Esophageal High-Resolution Manometry in Clinical Practice: First, Do HRM. AB - Esophageal high-resolution manometry (HRM) has advanced the understanding of esophageal motor function and the ability to diagnose and manage disorders of esophageal motility. In this review, we describe the indications for and the technical performance of HRM. The Chicago classification of esophageal motor function, now in its third iteration, streamlines and standardizes the nomenclature and basic interpretation of HRM data depicted as Clouse topographic plots. In clinical practice, HRM is an important diagnostic test for patients with dysphagia as well as patients with suspected gastroesophageal reflux disease (GERD), particularly in those patients with a suboptimal symptomatic response to antisecretory therapy. HRM can support diagnoses such as achalasia, as well as provide evidence for behavioral disorders such as rumination syndrome or supragastric belching with the assistance of postprandial HRM with impedance. Further, the GERD classification of motor function introduces a three-part hierarchical evaluation of esophageal motor function in GERD, highlighting the value of assessment of esophageal contractile reserve through provocative maneuvers during HRM such as multiple rapid swallows. PMID- 30276574 TI - Body composition assessment and sarcopenia in patients with gastric cancer: a systematic review and meta-analysis. AB - INTRODUCTION: There has recently been increased interest in the assessment of body composition in patients with gastric cancer for the purpose of prognostication. This systematic review and meta-analysis aim to evaluate the current literature on body composition assessment in patients with gastric cancer and its impact on peri-operative outcomes. METHODS: A systematic literature search was conducted for studies reporting assessment of body composition in patients with gastric cancers. Meta-analysis of postoperative outcomes (overall and major complications, anastomotic leaks, pulmonary complications) and survival was performed using random effects models. RESULTS: Thirty-nine studies reported the assessment of body composition in 8402 patients. Methods used to assess body composition in patients with gastric cancers were computerized tomography (n = 26), bioelectrical impedance analysis (n = 9), and dual-energy-X-ray absorptiometry (n = 3). Only 21 studies reported the impact of pre-operative sarcopenia on post-operative outcomes. Sarcopenic patients have significantly higher rates of postoperative major complications (n = 12, OR 1.67, CI95% 1.14 2.46, p = 0.009), and pulmonary (n = 8, OR 4.01, CI95% 2.23-7.21, p < 0.001) complications after gastrectomy. Meta-analysis of nine studies reporting overall survival after gastrectomy identified significantly worse survival in patients with pre-operative sarcopenia (HR 2.12, CI95% 1.89-2.38, p < 0.001). CONCLUSIONS: Assessment of body composition has the potential to become a clinically useful tool that could support decision-making in patients with gastric cancer. However, variation in methods of assessing and reporting body composition in this patient group limits assessment of current post-operative outcomes. PMID- 30276572 TI - Identification and characterization of N-glycosylation site on a Mucor circinelloides aspartic protease expressed in Pichia pastoris: effect on secretion, activity and thermo-stability. AB - Methylotrophic yeasts have widely been used as model organisms for understanding cellular functions and biochemical activities in lower eukaryotes. The gene encoding an aspartic protease (MCAP) from Mucor circinelloides DSM 2183 was cloned and expressed into Pichia pastoris using both the native M. circinelloides signal peptide (mcSP) and alpha-factor secretion signal from Saccharomyces cerevisiae (alpha-MF). When expressed in P. pastoris using alpha-MF and mcSP, MCAP was secreted into the culture medium at a concentration 200 mg L-1 (410 MCU mL-1) and 110 mg L-1 (249 MCU mL-1), respectively. The SDS-PAGE analysis of each culture shows that the protein was secreted in the media in two forms with molecular weights of approximately 33 and 37 kDa. Upon digestion using endoglycosidase H (Endo H), only one band at 33 kDa was observed, indicating that the protein might be glycosylated. One putative N-glycosylation site was found and a site-directed mutagenesis at position Asn331-Gln of the sequence produce only one form of the protein of 33 kDa, similar to that obtained when digested with Endo H. The optimum temperature and pH activity of the expressed MCAP was found to be at 60 degrees C and 3.6, respectively. PMID- 30276575 TI - Olfactory function in patients after transsphenoidal surgery for pituitary adenomas-a short review. AB - Olfaction is an important sensory input that obviously affects many daily activities. However, olfactory dysfunction (hyposmia and anosmia) leads to a pronounced decrease in quality of life. Surprisingly, little attention has been paid to olfactory changes after transsphenoidal surgery for pituitary tumors. In this review, we summarize current knowledge of the effects of transsphenoidal pituitary surgery on olfaction and compare different surgical techniques. Based on selected studies, the endoscopic approach, in comparison with the microscopic approach, seems to be superior in terms of preservation of olfactory function, although the quality of data from these studies is generally poor. The best results were observed when the endoscopic approach was used without harvesting of the nasoseptal flap.

AB - The elimination of egg stickiness is required for effective artificial reproduction of northern pike, but until now, available methods have required at least 40 min. Sodium hypochlorite was tested under laboratory conditions, and exposure to aqueous concentrations of 0.025-0.05% for 40 s effectively eliminated stickiness without adverse effects. Fertilization and hatching rates in laboratory trials were similar to those observed in eggs treated with traditional methods using clay or milk for 40 or 60 min, respectively, as well as those without treatment. Testing using conventional hatchery incubation techniques did not reveal differences in fertilization rates, while the number of hatched larva was significantly higher in eggs treated with sodium hypochlorite vs. clay. Eggs treated with sodium hypochlorite retained transparency, which facilitated monitoring of embryo development. PMID- 30276577 TI - Molecular identification of dmrt1 and its promoter CpG methylation in correlation with gene expression during gonad development in Culter alburnus. AB - Dmrt1, a member of the Dmrt family, is an important transcription regulator of gender determination. To study the biological function of dmrt1 in sexual differentiation and its potential implication in breeding technology, we obtained the full-length cDNA and proximal promoter sequence of dmrt1 in Culter alburnus, and analyzed the impact of promoter CpG methylation on the gene expression pattern of dmrt1 during gonad development. Dmrt1 was 922 bp in length and consisted a 150 bp 5'-UTR, a 28 bp 3'-UTR, and a 744 bp open reading frame (ORF). Based on the coding sequence of the dmrt1 gene, the deduced amino acid sequence was detected, and the protein structure of this gene was predicted in C. alburnus. The results indicate that the structure and function of dmrt1 were highly conservative compared to other vertebrates. The expression level of dmrt1 mRNA in different tissues was explored by qRT-PCR, which was only highly expressed in the testes and almost undetectable in other tissues. The CpG methylation pattern of the dmrt1 promoter was studied using DNA sequencing of sodium bisulfite in adult testes and ovaries, and it was found that dmrt1 promoter CpGs were not methylated in the testes, whereas hypermethylated in the ovaries. These findings demonstrate that DNA methylation can regulate sexual dimorphic expression of dmrt1, and therefore epigenetic modifications may play a critical role in the gonad differentiation of C. alburnus. PMID- 30276578 TI - Effects of multiwalled carbon nanotubes and carbofuran on metabolism in Astyanax ribeirae, a native species. AB - The study of the toxic effect of carbofuran and multiwalled carbon nanotubes (MWCNTs) on Astyanax ribeirae metabolism is of paramount importance due to the increasing use of this pesticide in agriculture and in the production of nanotubes within the material industry. This study aimed to evaluate the effects of carbofuran, MWCNT, and the combination of these compounds on specific oxygen consumption and excretion of ammonia in A. ribeirae. Therefore, 65 fish were divided into three groups of treatments at varying concentrations: carbofuran (0.01, 0.05, 0.1, and 0.5 mg/L), MWCNT (0.1, 0.25, 0.5, and 1.0 mg/L), and 0.5 mg/L of MWCNT added to carbofuran concentrations (0.01, 0.05, 0.1, and 0.5 mg/L). The average specific oxygen consumption in the groups exposed to carbofuran, compared to the control, increased 73.49% at the 0.01 mg/L concentration and decreased 63.86% and 91.57% with treatments of 0.1 and 0.5 mg/L, respectively. For groups exposed to the MWCNT, there was an 83.91% drop with the 1.0 mg/L treatment, and the carbofuran + MWCNT groups recorded a decrease of 71.09%, 92.77%, and 93.98% at concentrations of 0.05, 0.1, and 0.5 mg/L, respectively. In relation to specific ammonia excretion, in groups exposed to carbofuran compared to the control, there was an increase of 134.37% and 200% with the 0.1 and 0.5 mg/L treatments, respectively. The group exposed to carbofuran + MWCNT experienced a decrease of 60% and 80% with treatments of 0.1 mg/L carbofuran + 0.5 mg/L MWCNT and 0.5 mg/L carbofuran + 0.5 mg/L MWCNT, respectively. Therefore, it was concluded that carbofuran + MWCNT interact, increasing the effects in Astyanax sp. PMID- 30276579 TI - Effect of diphenyliodonium hexafluorophosphate salt on experimental infiltrants containing different diluents. AB - Non-invasive treatments for caries lesions are increasingly required for oral health; resin infiltration is one possible conservative option. In this study, we evaluated the effects of diphenyliodonium hexafluorophosphate salt (DPI) on experimental resin infiltrants with either (hydroxyethyl)methacrylate (HEMA) or ethanol as the diluent. A monomeric base with diglycidyl methacrylate ethoxylated (BisEMA, 25 wt%) and triethylene glycol dimethacrylate (TEGDMA, 75 wt%), 0.5 mol% of camphorquinone, and 1 mol% of ethyl-4-(dimethylamino)benzoate (EDAB) was prepared. The mixtures were divided into 12 groups according to DPI concentration (0; 0.25; 0.5; 1 mol%) and diluents (10 wt% HEMA, 10 wt% ethanol, or none). Degree of conversion (DC), water sorption (Ws), solubility (Sol), contact angle (CA), and cohesive strength (CS) tests were performed and compared to a commercial infiltrant control group (Icon). Only ethanol negatively affected DC and Sol, but both diluents negatively affected Ws and CS. Nevertheless, the presence of DPI, mainly at the 0.5 mol% concentration, compensated for the negative effects of the diluents. The commercial control group was less effective only for CS. In conclusion, 0.5% DPI seems to be the most suitable concentration to compensate for the negative effects of diluents. PMID- 30276580 TI - Influence of the final irrigation solution on the push-out bond strength of calcium silicate-based, epoxy resin-based and silicone-based endodontic sealers. AB - The aim was to evaluate the influence of different irrigation solutions on the push-out bond strength (POBS) of three different sealers (AH Plus, BioRoot RCS, GuttaFlow2). Root canals of 180 single-rooted human teeth were instrumented with F360 up to size 45.04. All canals were irrigated with 5 ml NaOCl 3% and 5 ml EDTA 17%. The canals were finally irrigated with either 5 ml NaOCl 3%, CHX 2%, EDTA 17%, citric acid 20% or NaCl 0.9% (n = 36) with a contact time of 5 min and obturated using matching gutta-percha cones according to the single-cone technique in combination with one of the sealers (n = 12). After 8 weeks of incubation, the roots were embedded in resin. Two slices of 1 mm thickness were obtained representing the middle third of the root. Dislodgement resistance was measured and POBS was calculated. Specimens were examined under 4* magnification to determine the mode of bond failure. Statistical analysis was performed using two-way ANOVA and Student-Newman-Keuls test for POBS and Chi-square test for the mode of failure. POBS was significantly affected by the factor "sealer" (P < 0.001) and by the interaction "sealer/irrigation solution" (P < 0.01). AH Plus revealed significantly higher POBS than BioRoot RCS and GuttaFlow2 (P < 0.05). The POBS of GutttaFlow2 was not affected by the irrigation protocol (P > 0.05). The POBS of AH Plus was positively influenced by EDTA and NaOCl. EDTA had a negative effect on the POBS of BioRoot RCS. The POBS of GuttaFlow2 was not influenced by the irrigation solutions.

PMID- 30276584 TI - Sensitive and specific assay for the simultaneous detection of Mycoplasma genitalium and macrolide resistance-associated mutations. AB - Patients infected by Mycoplasma genitalium are often treated empirically with the macrolide azithromycin. Macrolide resistance is becoming quite common; empirical treatment is compromised. Sequencing was initially used to detected azithromycin resistance-associated mutations. As this was laborious, qPCRs have been developed for their detection. In the present study, we describe a fast, sensitive, and specific qPCR assay that enables routine testing of M. genitalium and macrolide resistance-associated mutations in a single assay. M. genitalium positive clinical samples were used to compare (i) the commonly used MgPa assay for the detection of M. genitalium infections (MgPa qPCR), (ii) a combined 23S rRNA gene PCR/sequencing assay (Mg23S qPCR/Sequencing) to identify macrolide resistance associated mutations, and (iii) our newly developed probe-based melt curve qPCR for simultaneous detection of M. genitalium and macrolide resistance-associated mutations (Macrolide-R/MG ELITe MGB Kit, Elitech Bothel USA in short Mg MacrolideR qPCR). Specificity of the qPCR was tested using urogenital samples that were tested positive for a range of other micro-organisms. M. genitalium was detected in 196/236 (83.1%) samples by the MgPa qPCR, versus 172/236 (72.9%) by the combined Mg23S qPCR/Sequencing, and 202/236 (85.6%) by the Mg MacrolideR qPCR. The Mg MacrolideR qPCR showed high concordance to the Mg23S qPCR/Sequencing assay (201 vs 202 could be genotyped, respectively) for the detection of the macrolide resistant mutations. None of the other urogenital pathogens were tested positive in the Mg MacrolideR qPCR, indicating specificity. The Mg MacrolideR qPCR is fast, sensitive, specific, and can easily be implemented in the routine diagnostics. PMID- 30276586 TI - Structure, electronic properties, and NBO and TD-DFT analyses of nickel(II), zinc(II), and palladium(II) complexes based on Schiff-base ligands. AB - In this work we studied the structural and electronic properties of the metal Schiff base complexes Ni[Formula: see text] (1), Pd[Formula: see text] (2), Zn[Formula: see text] (3), and Ni[Formula: see text](4), where L1 and L2 are Schiff bases synthesized from salicylaldehyde and 2-hydroxy-5-methylbenzaldehyde, respectively. Natural bond analysis showed that in complexes 1 and 2, the metal ion coordinates to the ligands through electron donation from lone pairs on ligand nitrogen and oxygen atoms to s and d orbitals on the metal ion. In complex 3, metal-N and metal-O bonds are formed through charge transfer from the lone pairs on nitrogen and oxygen atoms to an s orbital of Zn. Dimethylation of the phenolate rings in the ligands decreases the energy gap and redshifts the spectrum of the nickel complex. The main absorptions observed were assigned on the basis of singlet-state transitions. The simulated spectra of the two complexes 1 and 2 are characterized by excited states with ligand-to-ligand charge-transfer (LLCT), metal-to-ligand charge-transfer (MLCT), ligand-to-metal charge-transfer (LMCT), and metal-centered (MC) character.

AB - An assortment of organic material can leach from lignite (low-rank coal) in water, and the water-soluble fraction from lignite has been associated with adverse health effects in areas of the Balkans. Recent efforts have been made to evaluate this hypothesis in other areas where lignite is in contact with groundwater like in the U.S. Gulf Coast region. In this study, five Gulf Coast lignite samples were extracted with water, and the water-soluble portion of the coal was then characterized by total organic carbon, UV-Vis spectroscopy, and gas chromatography/mass spectrometry. Additionally, human kidney cells (HK-2) were exposed to water-soluble extracts of Gulf Coast lignite to assess toxicity. Cell viability was measured, and a dose-response curve was used to generate IC50 values that ranged from 490 to 3000 ppm. The most toxic extract (Dolet Hills) was from Louisiana where lignite-derived organic material has been previously linked to high incidence of renal pelvic cancer. Concentrations of nephrotoxic metals (As, Cd, Co, Cu, Hg, Pb, V, Zn) were screened and were below those considered toxic to renal cells. We conclude that leachates from lignite do indeed have toxic affects on cultured human renal cells. Although the IC50 values are higher than the concentration of organic matter in the local groundwater, typically < 5 ppm, the effects of long-term low-level exposure is not known.

PMID- 30276588 TI - The Prognostic Impact of KRAS Mutation in Patients Having Curative Resection of Synchronous Colorectal Liver Metastases. AB - BACKGROUND: m-KRAS has been recently reported to be a significant prognostic factor in patients undergoing resection of colorectal liver metastases. This is due to the lack of response to monoclonal epithelial growth factor receptor antibodies, and potentially as a result of a more aggressive tumor biology. METHODS: The National Cancer Database was queried to identify patients with known KRAS status presenting with colorectal cancer and liver metastases who underwent resection of the primary tumor and metastatic disease between 2010 and 2015. RESULTS: A total of 2655 patients were identified of which 1116 (42%) had m-KRAS. Tumor size, lymph node involvement rates, and margin status of the primary tumor were similar between patients with m-KRAS and wild-type KRAS (wt-KRAS). In the multivariable analysis, African-American race and right-sided colon cancers were independently associated with m-KRAS (both p < 0.001). m-KRAS patients had a significantly lower overall survival (OS) than those with wt-KRAS, with a 3- and 5-year OS of 51 vs. 64% and 31 vs. 42%, respectively (p < 0.001). After adjustment for available prognostic confounders, factors independently associated with worse OS were increasing age, receipt of monoagent chemotherapy, tumor size, positive lymph node, and resection margin status of the primary tumor, right sided cancers, and m-KRAS. CONCLUSIONS: m-KRAS is associated with worse OS in patients presenting with colorectal cancer and liver metastases undergoing resection of the primary tumor and metastatic disease. Right-sided lesions and African-American race were associated with m-KRAS. However, while right-sided remained an independent prognostic factor for OS, race did not. PMID- 30276585 TI - The Toll Pathway in the Central Nervous System of Flies and Mammals. AB - Toll receptors, first identified to regulate embryogenesis and immune responses in the adult fly and subsequently defined as the principal sensors of infection in mammals, are increasingly appreciated for their impact on the homeostasis of the central as well as the peripheral nervous systems. Whereas in the context of immunity, the fly Toll and the mammalian TLR pathways have been researched in parallel, the expression pattern and functionality have largely been researched disparately. Herein, we provide data on the expression pattern of the Toll homologues, signaling components, and downstream effectors in ten different cell populations of the adult fly central nervous system (CNS). We have compared the expression of the different Toll pathways in the fly to the expression of TLRs in the mouse brain and discussed the implications with respect to commonalities, differences, and future perspectives. PMID- 30276591 TI - Updates in medical professional liability: a primer for electrophysiologists. AB - Medical professional liability (MPL), traditionally known as medical malpractice, affects most electrophysiologists some point during their career, either directly through personal experience or indirectly by the experiences of colleagues. Despite this, most physicians struggle to accurately describe MPL in the context of clinical practice. Providers know little about the outcomes of malpractice claims as reporting of settled or litigated MPL cases is sparse in the medical literature. In the USA, individual patients can file a malpractice claim in a tort-based system, whereas in other parts of the world, no-fault malpractice systems are increasingly prevalent. Tort reform remains a topic of much debate as the economic costs of malpractice contribute to the ever-expanding costs of health care in the USA. This review provides a framework to define MPL, describes the tort and no-fault systems of malpractice, and details the economic impacts of MPL on health care and the practice of cardiology in the USA. Current policy trends towards MPL including tort reform are reviewed, and MPL as it relates to the practice of cardiac electrophysiology is detailed. PMID- 30276592 TI - Remote monitoring of subcutaneous implantable cardioverter defibrillators. AB - BACKGROUND: Remote monitoring (RM) of implantable cardioverter defibrillators (ICD) has been shown to improve patient safety and reduce in-office visits. The subcutaneous ICD (S-ICD) is an effective alternative to transvenous ICD and has recently been endowed with the RM function. However, the RM communicator for S ICD requires patient interaction to activate data transmission. We assessed patient compliance and acceptance. METHODS: Patients with S-ICD received the communicator and were followed up for 15 months. Weekly remote transmissions were programmed. Compliance with checks was measured as the number of checks performed by the patient divided by the number of automatic notifications by the communicator. A questionnaire on acceptance of the system was administered to patients. RESULTS: A total of 106 patients were analyzed. The proportion of weekly checks properly executed by the patients was 94% during the first 3 months and 93% from months 12 to 15. Of the checks performed, 93% were on the same day as the automatic notification. On a patient basis, compliance with weekly checks was > 85% (less than one check missed per month) in 88% of patients during the first 3 months and in 82% from months 12 to 15 (p = 0.615). No variables emerged as predictors of lower (<= 85%) long-term compliance with weekly checks. During follow-up, 49 alerts were transmitted and the mean delay between the detected event and the patient transmission was 2 +/- 2 days. The majority of patients found the system easy to use and felt confident about being remotely monitored. CONCLUSIONS: The level of patient compliance with remote checks is high with current technology for RM of S-ICD. The vast majority of data transmissions are consistently performed on a weekly basis on the day scheduled. PMID- 30276593 TI - Maternal cinnamon intake during lactation led to visceral obesity and hepatic metabolic dysfunction in the adult male offspring. AB - PURPOSE: Studies with foods, known to promote health benefits in addition to the nutritive value, show that their consumption by pregnant and/or lactating females could induce negative outcomes to the offspring. It is well characterized that cinnamon intake promotes benefits to energy homeostasis. The present study aimed to analyze the effects of the consumption of an aqueous extract of cinnamon by lactating female rats on the endocrine-metabolic outcomes in the adult offspring. METHODS: Lactating dams (Wistar rats) were supplemented with cinnamon aqueous extract (400 mg/kg body weight/day) for the entire lactating period. The male adult offspring were evaluated at 180 days old (CinLac). RESULTS: The offspring presented visceral obesity (P = 0.001), hyperleptinemia (P = 0.002), and hyperinsulinemia (P = 0.016). In the liver, CinLac exhibited reduced p-IRbeta (P = 0.018) suggesting insulin resistance. However, phosphorylation of IRS1 (P = 0.041) and AKT (P = 0.050) were increased. JAK2 (P = 0.030) and p-STAT3 (P = 0.015) expressions were higher, suggesting that the activation of IRS1/AKT in the CinLac group could have resulted from the increased activation of leptin signaling. Although we observed no changes in the gluconeogenic pathway, the CinLac group exhibited lower hepatic glycogen content (P = 0.005) accompanied by increased p-GSK3beta (P = 0.011). In addition, the CinLac group showed increased hepatic triacylglycerol content (P = 0.049) and a mild steatosis (P = 0.001), accompanied by reduced PPARalpha mRNA expression (P = 0.005). CONCLUSION: We conclude that maternal intake of aqueous extract of cinnamon induces long-term molecular, metabolic, and hormonal changes in the adult progeny, including visceral obesity, higher lipid accumulation, and lower glycogen content in the liver. PMID- 30276594 TI - Posterior pituitary tumours: the spectrum of a unique entity. A clinical and histological study of a large case series. AB - PURPOSE: In 2017, the WHO established that pituicytoma, granular cell tumour (GCT) and spindle cell oncocytoma (SCO) are posterior pituitary tumours (PPT). Recent data suggests that these tumours probably arise from the pituicytes and may constitute a spectrum of a unique histopathological entity. Our aim is to report the clinical findings and surgical outcomes of 16 patients with PPT. We also evaluated the tissue specimens available in light of current knowledge. METHOD: Cross-sectional study with retrospective data. RESULTS: PPT were 7 pituicytomas, 3 GCT and 6 SCO. Patients mean age was 55 years old and 75% were female. Basal hormonal study showed hyperprolactinemia (43.7%) and hypopituitarism (37.5%). There was no case of diabetes insipidus (DI). MRI showed sellar/suprasellar masses with mean size of 19.7mm. PPT was not suspected in any patient. Fifteen patients underwent surgery and complications were common: 20% had perioperative bleeding (one patient died because of a massive haemorrhage), 57.1% hypopituitarism, 35.7% permanent DI and 21.4% underwent a second surgery. Pathological findings shown positivity for thyroid transcription factor 1, vimentin and negativity for cytokeratin and chromogranin A in all specimens evaluated. S100 protein was positive in 88.8% of tumours. Ki67 was >= 3% in 66.6% and ranged from 4-7% in SCO. CONCLUSION: PPT have similar histology, clinical features and are frequently misdiagnosed as nonfunctioning pituitary tumours. However, post-surgical complications including haemorrhage are common. A high clinical suspicion is needed to presume the diagnosis prior surgery and diminish the high morbidity of these tumours. PMID- 30276595 TI - Diagnostic value of ultrasonography and TI-201/Tc-99m dual scintigraphy in differentiating between benign and malignant thyroid nodules. AB - PURPOSE: To evaluate the performance of ultrasonography (US) and TI-201/Tc-99m dual (Tl/Tc) scintigraphy in differentiating between benign and malignant thyroid nodules. METHODS: Eighty-six patients diagnosed to have a thyroid tumor on postoperative histopathologic examination between June 2009 and February 2017 were included in this retrospective study. A radiologist reviewed the US and Tl/Tc scintigraphy reports along with all available clinical and histopathologic information. On Tl/Tc scintigraphy, a nodule in which uptake was higher in the delayed phase than in the surrounding parenchyma was defined as a delayed accumulation pattern and a nodule in which uptake was higher in the delayed phase than in the early phase was defined as a persistent pattern. The Tl/Tc scintigraphy images were evaluated in a blinded manner to assess reproducibility. A statistical analysis was performed to identify features associated with malignancy. Interobserver variability was calculated using the kappa statistic. RESULTS: US had higher sensitivity (81.2%), specificity (88.2%), and positive (96.6%) and negative (53.6%) predictive values than Tl/Tc scintigraphy. An ill defined margin and microcalcification were independent predictors of a malignant thyroid nodule on multivariate logistic regression (P = 0.003 and P = 0.014, respectively). The persistent pattern had high specificity (85.7%) equivalent to that of US but had lower sensitivity (34.7%). The kappa values for the delayed accumulation and persistent patterns were 0.66-0.78 and 0.32-0.50, respectively. CONCLUSIONS: An ill-defined margin and microcalcification on US were independent predictors of a malignant thyroid nodule. A persistent pattern seen on Tl/Tc scintigraphy could contribute to the differential diagnosis. PMID- 30276597 TI - Minichromosome maintenance complex component 8 and 9 gene expression in the menstrual cycle and unexplained primary ovarian insufficiency. AB - PURPOSE: DNA repair genes Minichromosome maintenance complex component (MCM) 8 and 9 have been linked with gonadal development, primary ovarian insufficiency (POI), and age at menopause. Our objective was to characterize MCM 8 and 9 gene expression in the menstrual cycle, and to compare MCM 8/9 expression in POI vs normo-ovulatory women. METHODS: Normo-ovulatory controls (n = 11) and unexplained POI subjects (n = 6) were recruited. Controls provided three blood samples within one menstrual cycle: (1) early follicular phase, (2) ovulation, and (3) mid luteal phase. Six of 11 controls only provided a follicular phase sample. Amenorrheic POI subjects provided a single, random blood sample. MCM8/9 expression in peripheral blood was assessed with qRTPCR. Analyses were performed using delta-Ct measurements; group differences were transformed to a fold change (FC) and confidence interval (CI). Differences across menstrual cycle phases were compared using random effects ANOVA. Two-sample t tests were used to compare two groups. RESULTS: MCM8 expression was significantly lower at ovulation and during the luteal phase, when compared to the follicular phase [FC = 0.69 in the luteal vs follicular phase (p = 0.012, CI = 0.53, 0.90); and 0.65 in the ovulatory vs follicular phase (p = 0.0057, CI = 0.50, 0.85)]. No change in MCM9 expression was noted throughout the menstrual cycle. No significant difference was seen in MCM8/9 expression when comparing POI to control subjects. CONCLUSIONS: Our study showed greater MCM8 expression in the follicular phase of the menstrual cycle, compared to the ovulatory and luteal phases. No cyclic changes were seen with MCM9. Significant differences in MCM8/9 expression were not detected between POI and controls; however, we recommend further investigation with a larger sample population. PMID- 30276598 TI - Persistence Mindset among Adolescents: Who Benefits from the Message that Academic Struggles are Normal and Temporary? AB - Research proposing that mindset interventions promote student achievement has been conducted at a frenetic pace nationwide in the United States, with many studies yielding mixed results. The present study explores the hypothesis that mindset interventions are beneficial for students only under specific circumstances. Using a randomized controlled trial with student-level random assignment within two public schools (School 1: n = 198 seventh-graders, 73% Black, 27% White, 53% male; School 2: n = 400 ninth-graders, 98% White, 2% Black, 52% male), this trial conceptually integrated elements from three evidence-based mindset interventions. It then examined two theoretically driven moderators of student performance following the transition to middle or high school: students' racial backgrounds and students' educational expectations. Results indicated that the intervention was effective for a particular subset of students-Black students with high educational expectations-resulting in higher grades over the course of the year. Among students with low educational expectations (regardless of race), the intervention did not impact grades. For White students with high educational expectations, the control activities actually benefitted grades more than the mindset intervention. Both theoretical and practical implications for mindset research are discussed. PMID- 30276599 TI - The evaluation of prostate lesions with IVIM DWI and MR perfusion parameters at 3T MRI. AB - PURPOSE: The purpose of our study was to analyze the difference between IVIM DWI and perfusion parameters of malignant lesions and benign lesions-normal prostate tissue. METHODS: This prospective study included 31 patients who had multiparametric prostate MRI with IVIM DWI due to elevated prostate-specific antigen level and clinical suspicion between February 2015 and September 2016. RESULTS: For peripheral zone, the mean values of Ktrans, Kep, iAUC, chi2 and f were significantly higher in malignant lesions, and the mean values of Dt were significantly lower in malignant lesions (p 0.00, p 0.02, p 0.00, p 0.02 and p 0.00, respectively). For transitional zone, the mean values of Ktrans, Ve, iAUC, chi2 and f were significantly higher in malignant lesions, and the mean values of Dp and Dt were significantly lower in malignant lesions (p 0.00, p 0.00, p 0.00, p 0.00, p 0.00, p 0.02 and p 0.00, respectively). For whole prostate gland, the mean values of Ktrans, Kep, Ve, iAUC, chi2 and f were significantly higher in malignant lesions, and the mean values of Dp and Dt were significantly lower in malignant lesions (p 0.00, p 0.03, p 0.00, p 0.00, p 0.00, p 0.01, p 0.04 and p 0.00, respectively). CONCLUSIONS: Restricted diffusion-pseudodiffusion and increased perfusion parameters are important to differentiate prostate cancer from benign pathologies. It is also important to keep in mind that transitional zone and peripheral zone tumors may have different perfusion and diffusion parameters. Future studies are needed to confirm our findings. PMID- 30276600 TI - Does neutrophyl to lymphocyte ratio really predict chronic kidney disease progression? AB - PURPOSE: Chronic kidney disease (CKD) is an inflammatory process. In addition to increased morbidity and mortality, inflammation also contributes to the progression of CKD. Neutrophil/lymphocyte ratio (NLR) is a marker of inflammation. Some recent data suggest that NLR may predict the progression of CKD. METHODS: In this study, 5-year data of 740 patients with stage 2-4 CKD were reviewed retrospectively. Demographic data, NLR, CRP, albumin, the amount of proteinuria were recorded. At the beginning and the end of follow-up the glomerular filtration rate (GFR) and the annual GFR decline rate were calculated. Patients were divided to high and low NLR group according to median value of their baseline NLR. Reaching stage 5 CKD or initiation of renal replacement therapy was determined as end-point for follow-up. RESULTS: The mean age was 62.8 +/- 0.57 years, eGFR 40 ml/min/1.73 m2, median NLR was 2.76. NLR increased as the CKD-stage increased. Mean follow-up time was 51.2 +/- 30 months and 21.4% of patients reached the end-point. NLR was significantly increased at follow-up (from 3.22 to 5.68, p < 0.001). Annual GFR loss and baseline CRP were higher but baseline albumin and GFR were lower of patients with high NLR. The percent of patients reaching the end-point was not different between the groups with high and low baseline NLR. Kaplan Meier analysis showed that patients with high NLR had significantly lower mean renal survival (86.5 months) than patients with low NLR (105 months) (p < 0.001). In the Cox-regression analysis NLR was not an independent predictor in reaching the end-point but presence of diabetes mellitus, younger age and low baseline eGFR were found effective. CONCLUSIONS: NLR is an indicator of inflammation in chronic kidney disease. It may not be an independent predictor of CKD progression except that the CKD is in a more advanced stage and reflects the associated inflammation. Classical risk factors such as DM and lower GFR are more powerful predictors of progression. PMID- 30276602 TI - Outcomes of laparoscopic resection of urachal remnants followed by novel umbilicoplasty. AB - OBJECTIVE: The purpose of the study was to report the outcomes of our modified techniques of laparoscopic urachal resection, followed by novel umbilical-plasty using dermal regenerative grafts for symptomatic urachal remnants. METHODS: Between March 2014 and December 2016, laparoscopic urachal resection was carried out on 45 patients with complaints of urachal remnants. After extraction of the specimen and closure of the fascia at the umbilical site, a 1-cm square section of dermal regeneration sheet (TERUDERMIS(r), Olympus) was suture retained between the fascia and the skin. Patient satisfaction with cosmesis was scored prospectively using the visual analogue scale (VAS). Perioperative records were reviewed to assess surgical outcomes. RESULTS: Laparoscopic urachal resection was successfully conducted via the transperitoneal approach. Postoperative bleeding was experienced in one patient (2.2%), which was subsequently controlled laparoscopically. Infection subsided with symptomatic relief in all patients. No symptomatic recurrences were encountered. Over 80% of patients (37/45) rated the cosmetic outcome of the plasty as good to excellent, with the median scores of 8 (range 5-10). CONCLUSIONS: Laparoscopic urachal resection is safe and curative with reasonable risk of complications. Novel umbilicoplasty using dermal regenerative graft is very simple technique and offers satisfactory cosmetic outcomes. Further follow-up and cosmesis evaluation are required. PMID- 30276601 TI - Decreased percentage of memory B cells is independently associated with increased susceptibility to infection in patients on maintenance hemodialysis. AB - PURPOSE: Infection is a common complication and cause of death in patients on maintenance hemodialysis (MHD). B lymphocytes, which are an important component of the immune system, play a significant role in defending against pathogen invasion. However, in patients on MHD, the connection between infection and B cell subsets remains largely unknown. Our study aims to clarify the potential role of the distribution of B cell subsets in the infection process in patients on MHD. METHODS: In this cross-sectional study, basic information was collected from 175 patients on MHD from July 2016 to July 2017 at Zhongshan Hospital, Fudan University. The distributions of the B cell subsets in patients with and without infection were analyzed using flow cytometry to determine the role of B lymphocyte subsets in the infection process in patients on MHD. RESULTS: Among the 175 patients, 45 suffered from infection. The respiratory tract was the most common infection site, accounting for 67.86% of all infections. After adjustment using multivariate logistic regression models, memory B cells [per 1% increase, odds ratio [95% confidence interval (CI)]: 0.949 (0.915, 0.984), P < 0.01], switched memory B cells [per 1% increase, odds ratio (95% CI): 0.939 (0.898, 0.982), P < 0.01], naive B cells [per 1% increase, odds ratio (95% CI): 1.042 (1.009, 1.075), P < 0.05] and IgG titers [per 1 g/L increase, odds ratio (95% CI): 0.779 (0.630, 0.963), P < 0.05] were independent risk factors for infection in dialysis patients. CONCLUSION: A decrease in memory B cells is independently associated with an increased risk of infection in patients on dialysis. PMID- 30276603 TI - Relation of serum spondin-2 levels with cardiac morphology and inflammatory parameters in hemodialysis patients. AB - PURPOSE: Cardiovascular diseases are the leading causes of mortality in chronic kidney disease. Spondin-2 (SP-2), an intrinsic cardio-protective factor, prevents maladaptive remodeling. We aimed to determine the relation between serum SP-2 levels and cardiac morphology along with inflammatory parameters in hemodialysis (HD) patients. METHOD: The study comprised a total of 95 patients (61 females) receiving HD treatment three times a week for at least 6 months, and a control group consisting of age and gender matched 62 subjects (34 females). SP-2 levels were determined by ELISA. Echocardiography, 24-h ambulatory blood pressure monitoring, and carotid artery intima-media thickness (CIMT) measurement were performed in all subjects. The relation of serum SP-2 levels with CIMT, echocardiographic parameters, CRP, and absolute neutrophil-to-lymphocyte count ratio (NLR) was evaluated by correlation analysis. RESULTS: SP-2 levels were found to be significantly higher in the HD group than the control group (16.660 [8.719-20.938] vs. 3.988 [2.702-8.042] ng/L; P < 0.001). CIMT, CRP, and NLR were also higher in HD group (P < 0.005, P < 0.001, and P < 0.001, respectively). Significantly positive correlation was found between SP-2 and left ventricular mass, left ventricular mass index, CRP, and NLR, but no correlation was determined between SP-2 and CIMT. SP-2 was not statistically significant variable for the determination of LVH in univariate logistic regression analysis [Wald = 2.375; OR (95% CI) = 1.000 (0.999-1.000), P = 0.123]. CONCLUSION: Serum SP-2 levels were higher in HD patients compared to the population with normal renal functions. The results suggest that SP-2, an uremic toxin, might be effective over a complex pathway in the inflammatory process and in the pathogenesis of cardiovascular diseases of patients under HD treatment. PMID- 30276605 TI - Stable nuclear transformation of rhodophyte species Porphyridium purpureum: advanced molecular tools and an optimized method. AB - A mutated phytoene desaturase (pds) gene, pds-L504R, conferring resistance to the herbicide norflurazon has been reported as a dominant selectable marker for the genetic engineering of microalgae (Steinbrenner and Sandmann in Appl Environ Microbiol 72:7477-7484, 2006; Prasad et al. in Appl Microbiol Biotechnol 98(20):8629-8639, 2014). However, this mutated genomic clone harbors several introns and the entire expression cassette including its native promoter and terminator has a length > 5.6 kb, making it unsuitable as a standard selection marker. Therefore, we designed a synthetic, short pds gene (syn-pds-int) by removing introns and unwanted internal restriction sites, adding suitable restriction sites for cloning purposes, and introduced the first intron from the Chlamydomonas reinhardtii RbcS2 gene close to the 5'end without changing the amino acid sequence. The syn-pds-int gene (1872 bp) was cloned into pCAMBIA 1380 under the control of a short sequence (615 bp) of the promoter of pds (pCAMBIA 1380-syn-pds-int). This vector and the plasmid pCAMBIA1380-pds-L504R hosting the mutated genomic pds were used for transformation studies. To broaden the existing transformation portfolio, the rhodophyte Porphyridium purpureum was targeted. Agrobacterium-mediated transformation of P. purpureum with both the forms of pds gene, pds-L504R or syn-pds-int, yielded norflurazon-resistant (NR) cells. This is the first report of a successful nuclear transformation of P. purpureum. Transformation efficiency and lethal norflurazon dosage were determined to evaluate the usefulness of syn-pds-int gene and functionality of the short promoter of pds. PCR and Southern blot analysis confirmed transgene integration into the microalga. Both forms of pds gene expressed efficiently as evidenced by the stability, tolerance and the qRT-PCR analysis. The molecular toolkits and transformation method presented here could be used to genetically engineer P. purpureum for fundamental studies as well as for the production of high-value added compounds. PMID- 30276604 TI - Serum endocan and circadian heart rate variability in non-dialysis stage 5 chronic kidney disease patients. AB - BACKGROUND: Chronic kidney disease (CKD) is very common now and is associated with high overall and cardiovascular mortality. Numerous studies have reported that elevated heart rate (HR) is a risk factor for cardiovascular mortality. We investigated the link between serum endocan and circadian heart rate variability in non-dialysis stage 5 CKD patients. METHODS: In a cross-sectional study, we enrolled 54 prevalent n non-dialysis stage 5 CKD patients (32 males, aged 48.2 +/ 14.92 years). HR was measured with an automatic system. Serum endocan level was analyzed by ELISA. RESULTS: Night/day HR ratio was independently predicted by serum endocan level (P < 0.01) and hypertension history (P < 0.05). Adjusted R2 of the model was 0.222. CONCLUSION: Increased serum endocan is significantly associated with circadian heart rate variability in non-dialysis stage 5 CKD patients. Further investigation is needed to explore the potential benefits of serum endocan lowering therapy in this patient group. PMID- 30276606 TI - Distally based anterolateral thigh flap: an underutilized option for peri patellar wound coverage. AB - Wound coverage in the supra-patellar area presents a significant challenge for orthopaedic and reconstructive surgeons due to the need for preservation of knee joint function but the paucity of regional soft tissue flaps available. While many orthopaedic and reconstructive surgeons make use of the rotational gastrocnemius flap for coverage of peri-patellar defects, this flap has certain limitations. The goal of this study was to report a single-centre experience with the use of the distally based anterolateral thigh flap (ALT) and review the current literature on the use of the ALT for peri-patellar defects. In this report, both a single-centre experience using distally based anterolateral thigh (ALT) island flaps for supra-patellar wound coverage and the existing literature on this topic were reviewed. A systematic literature review was performed to assess the use of the ALT for peri-patellar wounds. Five patients with a mean age of 69 underwent a distally based ALT flap for coverage of peri-patellar defects. Four out of 5 flaps survived at the end of their respective follow-up. Based on this combined experience, the distally based reverse-flow anterolateral thigh island flap represents a useful but relatively underutilized option for appropriately selected supra-patellar wounds due to minimal donor site morbidity, multiple flap components, and predictable pedicle anatomy. The flap's major weakness is its potentially unreliable venous drainage, requiring delay or secondary venous outflow anastomosis. Given the ALT flap's favourable profile, the authors recommend consideration for its use when managing a peri-patellar coverage wound issue. PMID- 30276609 TI - Search efficiency is not sufficient: The nature of search modulates stimulus driven attention. AB - It has long been debated whether or not a salient stimulus automatically attracts people's attention in visual search. Recent findings showed that a salient stimulus is likely to capture attention especially when the search process was inefficient due to high levels of competition between the target and distractors. Expanding these studies, the present study proposes that a specific nature of visual search, as well as search efficiency, determines whether or not a salient, task-irrelevant singleton stimulus captures attention. To test this proposition, we conducted three experiments, in which participants performed two visual search tasks whose underlying mechanisms are known to be different: orientation-feature search and Landolt-C search tasks. We found that color singleton distractors captured attention when participants performed the orientation-feature search task. The magnitude of this capture effect increased as search efficiency decreased. On the contrary, the capture by singleton distractors was not observed under the Landolt-C search task. This differential pattern of capture effect was not due to differences in search efficiency across the search tasks; even when search efficiency was controlled for, stimulus-driven capture of attention by a salient distractor was found only under the feature search. Based on these results, the present study suggests that in addition to search efficiency, the nature of search strategy and the extent to which attentional control is strained play crucial roles in observing stimulus-driven attentional capture in visual search. PMID- 30276608 TI - CXCR5 overexpression in HL-60 cells enhances chemotaxis toward CXCL13 without anticipated interaction partners or enhanced MAPK signaling. AB - CXCR5 is a serpentine receptor implicated in cell migration in lymphocytes and differentiation in leukocytes. It causes MAPK pathway activation and has known membrane partners for signaling. CXCR5 mRNA is reportedly expressed in neutrophils following isolation, but its role in this cellular context is unknown. CXCR5 is also expressed in HL-60 cells, a human acute myeloid leukemia line, following treatment with all-trans retinoic acid, which induces differentiation toward a neutrophil-like state. CXCR5 is necessary for this process; differentiation was crippled in CXCR5 knockout cells and enhanced in cells ectopically expressing it. Since CXCR5 has various membrane protein partners, we investigated whether CXCR5-driven all-trans retinoic acid-induced differentiation depends on its association with such partners. Pursuing this, we generated HL-60 cells overexpressing the protein. We found that CXCR5 drove migration toward its ligand, CXCL13, and probed for interactions with several candidates using flow cytometry-based Forster resonance energy transfer. Surprisingly, we did not detect interactions with any candidates, including three reported in other cellular contexts. Additionally, we observed no significant changes in all-trans retinoic acid-induced differentiation; this may be due to the stoichiometry of CXCR5 and partner receptors or CXCL13. The anticipated membrane partnerings were surprisingly apparently unnecessary for downstream CXCR5 signaling and all-trans retinoic acid-induced differentiation. PMID- 30276607 TI - A methyl 1H double quantum CPMG experiment to study protein conformational exchange. AB - Protein conformational changes play crucial roles in enabling function. The Carr Purcell-Meiboom-Gill (CPMG) experiment forms the basis for studying such dynamics when they involve the interconversion between highly populated and sparsely formed states, the latter having lifetimes ranging from ~ 0.5 to ~ 5 ms. Among the suite of experiments that have been developed are those that exploit methyl group probes by recording methyl 1H single quantum (Tugarinov and Kay in J Am Chem Soc 129:9514-9521, 2007) and triple quantum (Yuwen et al. in Angew Chem Int Ed Engl 55:11490-11494, 2016) relaxation dispersion profiles. Here we build upon these by developing a third experiment in which methyl 1H double quantum coherences evolve during a CPMG relaxation element. By fitting single, double, and triple quantum datasets, akin to recording the single quantum dataset at static magnetic fields of Bo, 2Bo and 3Bo, we show that accurate exchange values can be obtained even in cases where exchange rates exceed 10,000 s-1. The utility of the double quantum experiment is demonstrated with a pair of cavity mutants of T4 lysozyme (T4L) with ground and excited states interchanged and with exchange rates differing by fourfold (~ 900 s-1 and ~ 3600 s-1), as well as with a fast folding domain where the unfolded state lifetime is ~ 80 us.

AB - The determination of the fluorescence quantum yield of Propylparaben is introduced and applied to L-tyrosine as a standard by a new approach that can be applied to the pharmaceutical compound utilised in this study. The quantum yield is a critical figure of quality for the optical nature of a fluorophore. Numerous investigations have considered the glitter in both pharmaceutical and nature compounds for its medical and industrial significance. A straightforward method is detailed here to decide the quantum yield of Propylparaben in solution as an element of the fluorescence concentration. For this reason, L-Tyrosine is chosen as a fluorescence standard perspective to gauge the Propylparaben fluorescence quantum yield. The impacts of pH, solvents and flow rate on the assessment of quantum yield and quantum efficiency, for the reference and the solutions of Propylparaben, have been investigated. The results indicated that these parameters significantly influence the accuracy of the method. Diverse methods are concentrated on to represent distinctive quantum yield advancements with the quantum efficiency. The impact of these parameters was likewise considered. In this study, the application of the single method may be taken into consideration to compute quantum yield of Propylparaben, which was 0.36, and this is an exceptionally basic and general technique to solve the imperative issue of luminescence quantum yield assurance of other fluorescence compounds.

AB - Photophysical and electrochemical studies of DDP dye with Formamide and alkyl substituted amides were carried out in water. Addition of Formamide (F), Acetamide (ACM), N,N-Dimethylformamide (DMF), Dimethylacetamide (DMAC) to DDP dye result in an isosbestic point. A fluorescence enhancement of DDP dye is observed on the addition of amides. Apart from the fluorescence enhancement, the addition of formamide result in no significant shift in the position of emission maxima of DDP dye whereas addition of ACM and DMF result in a shift towards the blue and red region respectively. DDP dye exhibits three lifetime components which are unique in lifetime and amplitude. The fluorescence lifetime and relative amplitude of DDP dye varies significantly by addition of amides in aqueous solution which are influenced by amidewater hydrogen-bonding network and hydrophobic influences of the alkyl substituted amides. The nature of interaction between dye and amide be predominantly through hydrogen-bonding wherein the carbonyl oxygen (C=O) of amides are bonded to N-H hydrogen of DDP dye through water molecule. The existence of more than one microenvironment of DDP dye in aqueous phase is elucidated by Electrochemical Impedence Spectroscopy (EIS) through Nyquist plots wherein it signifies that there exist at least three different micro environments which support the existence of different fluorescence lifetimes. Fluorescence spectral technique is used as an efficient tool to elucidate the nature of interaction of water soluble probe with hydrogen bonding solutes is established in our studies.

PMID- 30276614 TI - Association Between Therapeutic Hypothermia and Outcomes in Patients with Non shockable Out-of-Hospital Cardiac Arrest Developed After Emergency Medical Service Arrival (SOS-KANTO 2012 Analysis Report). AB - BACKGROUND/OBJECTIVE: The outcomes of patients with non-shockable out-of-hospital cardiac arrest (non-shockable OHCA) are poorer than those of patients with shockable out-of-hospital cardiac arrest (shockable OHCA). In this retrospective study, we selected patients from the SOS-KANTO 2012 study with non-shockable OHCA that developed after emergency medical service (EMS) arrival and analyzed the effect of therapeutic hypothermia (TH) on non-shockable OHCA patients. METHODS: Of 16,452 patients who have definitive data on the 3-month outcome in the SOS KANTO 2012 study, we selected 241 patients who met the following criteria: age >= 18 years, normal spontaneous respiration or palpable pulse upon emergency medical services arrival, no ventricular fibrillation or pulseless ventricular tachycardia before hospital arrival, and achievement of spontaneous circulation without cardiopulmonary bypass. Patients were divided into two groups based on the presence or absence of TH and were analyzed. RESULTS: Of the 241 patients, 49 underwent TH. Univariate analysis showed that the 1-/3-month survival rates and favorable 3-month cerebral function outcome rates in the TH group were significantly better than the non-TH group (46% vs 19%, respectively, P < 0.001, 35% vs 12%, respectively, P < 0.001, 20% vs 7%, respectively, P = 0.01). Multivariate logistic regression analysis showed that TH was a significant, independent prognostic factor for cerebral function outcome. CONCLUSIONS: In this study, TH was an independent prognostic factor for the 3-month cerebral function outcome. Even in patients with non-shockable OHCA, TH may improve outcome if the interval from the onset of cardiopulmonary arrest is relatively short, and adequate cardiopulmonary resuscitation is initiated immediately after onset. PMID- 30276615 TI - Venous Thromboembolism Prophylaxis in Neurocritical Care Patients: Are Current Practices, Best Practices? AB - BACKGROUND/OBJECTIVES: Venous thromboembolism (VTE) is a leading cause of preventable, in-hospital deaths; critically ill patients have a higher risk. Effective and efficient strategies to prevent VTE exist; however, neurocritical care patients present unique challenges due to competing risk of bleeding. The objective of this study was to examine current VTE prophylaxis practices among neurocritical care patients, concordance with guideline-recommended care, and the association with clinical outcomes. METHODS: This retrospective cohort study of patients admitted to ten adult, medical-surgical and neurological intensive care units (ICUs) in nine hospitals between 2014 and 2017 using administrative and clinical data. Neurocritical care patients were classified based on the primary admission diagnosis. Concordance with guideline-recommended care was evaluated using recommendations from recent guidelines. RESULTS: 20.0% of 23,191 patients were classified as neurocritical care. Among neurocritical care patients, pharmacological VTE prophylaxis was administered on 60.9% of all ICU days, mechanical VTE prophylaxis on 46.9%, and no VTE prophylaxis on 12.2% of all ICU days. Type of VTE prophylaxis was associated with sex, neurological diagnosis, and invasive neurological monitoring. Fifty-six percentage of ICU days were guideline concordant but concordance varied by recommendation (range 6-100%) and by type of VTE prophylaxis recommended (p = 0.05); among patients where guidelines recommended use of pharmacologic prophylaxis, care was concordant 26.6% of ICU days, whereas for mechanical prophylaxis it was concordant 80.5% of ICU days. There was an overall improvement in guideline concordance on 2.3% of ICU days after the publication of the Society of Neurocritical Care guideline (p = 0.005). CONCLUSIONS: Neurocritical care patients commonly receive mechanical VTE prophylaxis despite guidelines recommending the use of pharmacological VTE prophylaxis. Our findings suggest uncertainty around best VTE prophylaxis practices for neurocritical care patients remains. PMID- 30276612 TI - Immune Cells After Ischemic Stroke Onset: Roles, Migration, and Target Intervention. AB - Ischemic stroke is one of the leading health issues and the major cause of permanent disability in adults worldwide. Energy depletion and hypoxia occurring after ischemic stroke result in cell death, which activates resident glia cells and promotes the peripheral immune cells breaching into brain performing various functions even contradictory effects. The infiltration of immune cells may mediate neuron apoptosis and escalate ischemic damage, while it enhances neuron repair, differentiation, and neuroregeneration. The central nervous system (CNS) is immune-privileged site as it is separated from the peripheral immune system by the blood-brain barrier (BBB). Pathologically, the diapedesis of peripheral immune cells to CNS is controlled by BBB and regulated by immune cells/endothelial interactions. As immune responses play a key role in modulating the progression of ischemic injury development, understanding the characteristics and the contribution on regulating inflammatory responses of glia cells and peripheral immune cells may provide novel approaches for potential therapies. This review summarizes the multistep process of periphery immune cell extravasation into brain parenchyma during immunosurveillance and chronic inflammation after ischemic stroke onset. Furthermore, the review highlights promising target intervention, which may promote the development of future therapeutics for ischemic stroke. PMID- 30276616 TI - Motivational deficits in schizophrenia relate to abnormalities in cortical learning rate signals. AB - Individuals from across the psychosis spectrum display impairments in reinforcement learning. In some individuals, these deficits may result from aberrations in reward prediction error (RPE) signaling, conveyed by dopaminergic projections to the ventral striatum (VS). However, there is mounting evidence that VS RPE signals are relatively intact in medicated people with schizophrenia (PSZ). We hypothesized that, in PSZ, reinforcement learning deficits often are not related to RPE signaling per se but rather their impact on learning and behavior (i.e., learning rate modulation), due to dysfunction in anterior cingulate and dorsomedial prefrontal cortex (dmPFC). Twenty-six PSZ and 23 healthy volunteers completed a probabilistic reinforcement learning paradigm with occasional, sudden, shifts in contingencies. Using computational modeling, we found evidence of an impairment in trial-wise learning rate modulation (alpha) in PSZ before and after a reinforcement contingency shift, expressed most in PSZ with more severe motivational deficits. In a subsample of 22 PSZ and 22 healthy volunteers, we found little evidence for between-group differences in VS RPE and dmPFC learning rate signals, as measured with fMRI. However, a follow-up psychophysiological interaction analysis revealed decreased dmPFC-VS connectivity concurrent with learning rate modulation, most prominently in individuals with the most severe motivational deficits. These findings point to an impairment in learning rate modulation in PSZ, leading to a reduced ability to adjust task behavior in response to unexpected outcomes. At the level of the brain, learning rate modulation deficits may be associated with decreased involvement of the dmPFC within a greater RL network. PMID- 30276617 TI - Transplantation of Cardiac Mesenchymal Stem Cell-Derived Exosomes for Angiogenesis. AB - We demonstrated the effects of exosomes secreted by cardiac mesenchymal stem cells (C-MSC-Exo) in protecting acute ischemic myocardium from reperfusion injury. To investigate the effect of exosomes from C-MSC on angiogenesis, we injected C-MSC-Exo or PBS intramuscularly into ischemic hind limb. Blood perfusion of limb was evaluated by laser Doppler Imaging. We observed that ischemic limb treated with C-MSC-Exo exhibits improved blood perfusion compared to ischemic limb treated with PBS at 2 weeks and 1 month after induction of limb ischemia. To explore the potential mechanisms underlying C-MSC-Exo's angiogenetic effect, we performed microRNA array analysis and identify mmu-miR-7116-5p as the most abundant enriched miRNA detected in C-MSC-Exo. Bioinformatics' analysis shows that miR-7116-5p negatively regulates protein polyubiquitination. In conclusion, our study demonstrated that intramuscular delivery of C-MSC-Exo after limb ischemia improves blood perfusion, and we identified the most abundant miRNAs that are preferentially enriched in C-MSC-Exo. PMID- 30276618 TI - Impact of Neutrophil-to-Lymphocyte Ratio and Platelet-to-Lymphocyte Ratio on 5 Year Clinical Outcomes of Patients with Stable Coronary Artery Disease Undergoing Elective Percutaneous Coronary Intervention. AB - The prognostic role of neutrophil-to-lymphocyte ratio (NLR) and platelet-to lymphocyte ratio (PLR) in patients with stable coronary artery disease (CAD) is still unclear. We enrolled 500 patients undergoing elective percutaneous coronary intervention (PCI). Blood samples were drawn prior to PCI for NLR and PLR calculation. Major adverse clinical events (MACE), which included death, myocardial infarction (MI), and target vessel revascularization (TVR), were recorded up to 5 years. Patients in the higher tertile of NLR presented higher Kaplan-Meier estimates of MACE (26.0% vs. 16.9% in tertile 2 vs. 14.3% in tertile 1; p = 0.042) and death (12.0% vs 6.9% in tertile 2 vs. 4.6% in tertile 1; p = 0.040), whereas there were no significant differences in the estimates of MI and TVR. NLR in the higher tertile was an independent predictor of MACE (HR 1.65, 95% CI 1.07-2.55, p = 0.024). No significant difference was observed across tertiles of PLR. Unlike PLR, elevated pre-procedural NLR is associated with an increased risk of 5-year clinical adverse events. PMID- 30276619 TI - A review of the diversity in taxonomy, definitions, scope, and roles in forensic medicine: implications for evidence-based practice. AB - The scope, roles, and tasks of forensic medicine and forensic medical experts currently vary widely between countries and legal systems, which has resulted in barriers to organization, standard setting, and quality assurance for practice in forensic medicine, including for reporting. The legal fact finder is thus confronted with variability in the quality, structure, and content of forensic medical reports. We sought to define and categorize the scope, methods, and practices that fall under the description of forensic medicine, the various issues encountered in current forensic medical practice, and the potential role of evidence-based practice in forensic medicine. We searched electronic databases and reviewed relevant articles, as well as conducting personal correspondences with forensic medical practitioners around the world, to obtain a description of current forensic medical practice. The terms forensic medicine, legal medicine, medical jurisprudence, medico-legal services, forensic pathology, and clinical forensic medicine are used with mixed interpretations in different countries. The systems and services rendered are not uniform either. The methods used by forensic medical practitioners are not always evidence-based, or based on standardized methods, and vary greatly between experts and centers. There are also no universally accepted guidelines to prepare a standard and admissible report. The lack of a uniform system in forensic medicine creates difficulties in assessing the development and performance of forensic medicine as a distinct discipline. To prepare evidence-based forensic medical reports, generally accepted guidelines are necessary.

PMID- 30276622 TI - Count-based method for specific binding ratio calculation in [I-123]FP-CIT SPECT analysis. AB - OBJECTIVE: To calculate the specific binding ratio (SBR) appropriately in dopamine transporter (DAT) imaging, a method for extracting the striatal volume of interest (VOI) was developed. METHODS: This study included 200 patients (72 +/ 10 years) who were suspected of parkinsonian syndromes (PS) or dementia with Lewy body (DLB). The patients were divided into three groups of PS with dopaminergic degeneration, DLB and non-PS after [123I]ioflupane (FP-CIT) SPECT and clinical follow-up. The image data were reconstructed with CT attenuation correction and scatter correction, and with only CT attenuation correction (CTAC). The new method extracted striatal VOI according to the high-level counts and the average striatum volume, and calculated SBR using the reference occipital counts. The SBR values for each patient were obtained using the Tossici-Bolt method (SBRBolt) and our method. Reproducibility of SBR calculation using our method was compared by two operators. RESULTS: The mean SBR values for the PS and DLB groups were significantly different from that of the non-PS group with both methods. The coefficients of variation of the SBR were significantly smaller with the proposed method compared with those of SBRBolt (p < 0.001), except for the CTAC images. There were no differences in SBR between the two operators using our method. The diagnostic accuracies with our method for the PS and DLB groups were 98.4 and 96.0%, respectively. CONCLUSION: Our new method for SBR calculation in the FP-CIT SPECT showed less coefficients of variation with high reproducibility, which would be useful for clinical diagnosis and in assessing the severity of diseases in follow-up studies.

PMID- 30276623 TI - Improvement of left ventricular function after successful radiofrequency catheter ablation in persistent atrial fibrillation with preserved left ventricular ejection fraction: a comprehensive echocardiographic assessment using two dimensional speckle tracking analysis. AB - BACKGROUND: A limited number of studies have investigated the effects of radiofrequency catheter ablation (RFCA) on left ventricular (LV) function and the left atrial (LA) size in patients with atrial fibrillation (AF). The purpose of this study was to conduct a comprehensive assessment of LV function in patients with AF with preserved left ventricular ejection fraction (LVEF) before and after RFCA. METHOD: A total of 30 consecutive patients with no recurrences after RFCA for persistent AF (age, 57.7 +/- 8.4 years) were enrolled. Transthoracic echocardiography was performed at the baseline and 6 months after the final RFCA using speckle tracking derived LV strain analysis. RESULTS: After RFCA, we measured decreases in the LA volume index (33.7 +/- 10.4 ml/m2 vs. 24.6 +/- 8.6 ml/m2, p < 0.0001), while we observed improvements in systolic indices such as LVEF (56.8 +/- 9.8% vs. 65.1 +/- 9.1%, p < 0.0001), global longitudinal strain (- 16.8 +/- 4.4% vs. - 18.8 +/- 3.4%, p = 0.0055) and twist (8.12 +/- 3.66 degrees vs. 12.33 +/- 6.75 degrees , p = 0.0050), and also in diastolic indices such as strain rate during early diastole (SRE) (0.73 +/- 0.10 s-1 vs. 1.32 +/- 0.29 s-1, p < 0.0001) and early transmitral inflow velocity (E)/SRE (1.11 +/- 0.36 m vs. 0.61 +/- 0.19 m, p < 0.0001). Logistic regression analysis showed that DeltaE/SRE was a contributing factor for improvement in LVEF (odds ratio 126.9; p = 0.021). CONCLUSION: In persistent AF with preserved LVEF, further improvement in LVEF and reverse remodeling of the LA are achieved after RFCA. LV filling pressure may play significant roles in the mechanisms. PMID- 30276624 TI - Risk of lung cancer and physical activity by smoking status and body mass index, the Norwegian Women and Cancer Study. AB - We aimed to investigate physical activity (PA) and risk of different histological subtypes of lung cancer according to smoking status and body mass index using repeated measurements in a large cohort of women in Norway. The study sample for the multiple imputation analyses consisted of 86,499 and for the complete-case analysis 80,802 women. Repeated measurements of PA level, smoking habits, weight, and height were available for 54,691 women (63.2%), who were included in repeated measurement analyses combined with multiple imputation to address attrition. Cox proportional hazards regression models were used to calculate hazard ratios with 95% confidence intervals. During a median follow-up of 12.9 years, 866 cases of primary lung cancer were identified. We found an inverse association between PA and lung cancer overall. The results were consistent from multiple imputed data analysis to complete-case analysis of PA and possible confounders. We observed a similar trend for adenocarcinoma, but not for squamous cell or small cell carcinomas. Our findings suggest a more pronounced association between lung cancer overall and PA levels in current and former smokers, and in normal-weight and overweight participants with increasing PA levels. The potential of a modifiable lifestyle factor as PA to reduce the risk of lung cancer independently of smoking status is important in public health.

AB - The ability to design detergents that are suitable for protein analysis by mass spectrometry (MS) represents an on-going challenge in the field of native MS. Desirable detergent characteristics include charge-reducing properties and low gas-phase stabilities of complexes formed with proteins. In this work, the gas phase properties of oligoglycerol detergents (OGDs) are optimized by fine tuning of their molecular structure. Furthermore, a tandem mass spectrometry (MS/MS) approach is presented that estimates the gas-phase properties of detergents simply by studying the dissociation behaviour of protein-detergent complexes (PDCs) formed with the soluble protein beta-lactoglobulin (BLG). Graphical Abstract ?. PMID- 30276625 TI - Conservative Treatment of Hemorrhoids: Results of an Observational Multicenter Study. AB - INTRODUCTION: This study was conducted to determine the frequency of complaints in a cohort of patients with symptomatic hemorrhoidal disease (HD) treated with micronized purified flavonoid fraction (MPFF, Detralex). MPFF was selected for conservative treatment in this population owing to its proven effects on hemorrhoidal symptoms in a large number of patients. METHODS: This multicenter, non-interventional study was part of the international CHORUS survey (Chronic venous and HemORrhoidal diseases evalUation for improvement of Scientific knowledge), conducted in nine centers in different regions of Russia with the participation of 80 coloproctologists. The study enrolled consecutive patients with complaints of hemorrhoids. All were prescribed MPFF-based conservative treatment. The effect of treatment on HD clinical signs and symptoms was assessed at two follow-up visits performed 5-7 days and 25-30 days after enrollment. Surgical and minimally invasive treatment could be performed from day 7 onwards if required. RESULTS: A total of 1952 patients were enrolled. Over the entire period of observation, MPFF-based conservative treatment was effective in 1489 (76.3%) patients in eliminating the main clinical manifestations of disease, i.e., bleeding and prolapse of internal nodes. Invasive treatment was performed in 68 (3.5%) patients with grade IV hemorrhoids and was combined with MPFF conservative treatment in 395 (20.2%) patients with grades I-III hemorrhoids. CONCLUSION: Conservative therapy with MPFF was beneficial for relieving hemorrhoidal symptoms in the majority of patients. MPFF-based treatment was most effective in patients with grade I and II hemorrhoids before irreversible degenerative changes in ligaments of the hemorrhoidal plexuses have occurred. It was also beneficial in preventing disease relapse in patients with more advanced HD and for promoting optimal conditions in the postoperative period. FUNDING: Servier. PMID- 30276627 TI - Determination of proper treatment time for in vivo blood coagulation and wound healing application by non-thermal helium plasma jet. AB - The aim of this research was to determine the time of blood coagulation of in vivo cuts that treated by the non-thermal atmospheric pressure plasma jet. Also, the effect of different treatment times on wound healing has been studied. The non-thermal atmospheric pressure plasma jet working in helium gas has been used. The averaged treatment time of 8.6 s for in vivo cuts on the Balb/c mouse liver showed the complete blood coagulation. Also, the effect of tretament time on wound healing has been studied by applying plasma on the wounds for different times (10, 20, 30, 40 and 50 s). It was obtained from morphological analysis that the treatment groups of 30 s, 40 s and 50 s cause the wounds to be healed faster than the groups 10 s and 20 s.The histological analysis showed that in 30 s and 40 s treatment time groups, the repair process of treated wounds has been accelerated, while for 50 s group, it has not been completed, yet. The 30 s treatment time has been chosen because of imposing lower dose to living tissue. The treated wound area reduction ratios against the control wound reduction ratios for 30 s group were obtained 78%, 77% and 63% at the 3rd, 5th and 8th days, respectively.

AB - Gonorrhea infections are becoming more difficult to treat due to the prevalence of strains exhibiting resistance to antibiotics and new therapeutic approaches are needed. N-acetylmuramyl-L-alanine amidase (AmiC) from Neisseria gonorrhoeae is a hydrolase that functions during cell division by cleaving the bond between the N-acetylmuramyl and L-alanine moieties of peptidoglycan. Inhibiting this enzyme offers the prospect of restoring the efficacy of existing antibiotics as treatments against N. gonorrhoeae. Of its two domains, the C-terminal domain catalyses the hydrolysis reaction and the N-terminal domain (NTD) is believed to target AmiC to its peptidoglycan substrate. Here, we report the 1H, 13C, and 15N resonance assignments of a 131 amino acid NTD construct of AmiC by heteronuclear NMR spectroscopy. The assignments represent the first for N. gonorrhoeae AmiC NTD, laying the groundwork for detailed examination of its structure and dynamics, and providing a platform for new drug discovery efforts to address antimicrobial-resistant N. gonorrhoeae. PMID- 30276629 TI - Best practices: Two Web-browser-based methods for stimulus presentation in behavioral experiments with high-resolution timing requirements. AB - The Web is a prominent platform for behavioral experiments, for many reasons (relative simplicity, ubiquity, and accessibility, among others). Over the last few years, many behavioral and social scientists have conducted Internet-based experiments using standard web technologies, both in native JavaScript and using research-oriented frameworks. At the same time, vendors of widely used web browsers have been working hard to improve the performance of their software. However, the goals of browser vendors do not always coincide with behavioral researchers' needs. Whereas vendors want high-performance browsers to respond almost instantly and to trade off accuracy for speed, researchers have the opposite trade-off goal, wanting their browser-based experiments to exactly match the experimental design and procedure. In this article, we review and test some of the best practices suggested by web-browser vendors, based on the features provided by new web standards, in order to optimize animations for browser-based behavioral experiments with high-resolution timing requirements. Using specialized hardware, we conducted four studies to determine the accuracy and precision of two different methods. The results using CSS animations in web browsers (Method 1) with GPU acceleration turned off showed biases that depend on the combination of browser and operating system. The results of tests on the latest versions of GPU-accelerated web browsers showed no frame loss in CSS animations. The same happened in many, but not all, of the tests conducted using requestAnimationFrame (Method 2) instead of CSS animations. Unbeknownst to many researchers, vendors of web browsers implement complex technologies that result in reduced quality of timing. Therefore, behavioral researchers interested in timing-dependent procedures should be cautious when developing browser-based experiments and should test the accuracy and precision of the whole experimental setup (web application, web browser, operating system, and hardware). PMID- 30276630 TI - Potential Direct Costs of Adverse Drug Events and Possible Cost Savings Achievable by their Prevention in Tuscany, Italy: A Model-Based Analysis. AB - INTRODUCTION: Adverse drug events (ADEs) may represent an important item of expenditure for healthcare systems and their prevention could be associated with a relevant cost saving. OBJECTIVE: The objective of this study was to simulate the annual economic burden for ADEs in Tuscany (Italy) and the potential cost savings related to avoidable ADEs. METHODS: A systematic review was performed, according to the Preferred Reporting Items for Systematic review and Meta Analysis (PRISMA) and Meta-analysis Of Observational Studies in Epidemiology (MOOSE) statements, on observational studies published from 2006 to 2016 in MEDLINE and EMBASE, focusing on direct costs of ADEs in the inpatient setting from high-income countries. The mean probability of preventable ADEs was estimated over the included studies. The mean ADE cost was calculated by means of Monte Carlo simulation. We then extrapolated the spontaneous reports of ADEs in Tuscany, Italy in 2016 from the Italian National Pharmacovigilance Network (Rete Nazionale di Farmacovigilanza), and we assumed the same costs and preventability probability for these as obtained in the systematic review. Finally, we simulated the possible costs of ADEs and preventable ADEs in Tuscany. Three sensitivity analyses were also performed to test the robustness of the results. RESULTS: Of 11,936 articles initially selected, 12 observational studies were included. The estimated mean [+/- standard deviation (SD)] ADE cost was ?2471.46 (+/- ?1214.13). The mean (+/- SD) probability of preventable ADEs was 45% (+/- 21). The Tuscan expenditure for ADEs was ?3,406,280.63 per million inhabitants (95% confidence interval (CI) 1,732,910.44-5,079,664.61) and the potential cost saving was ?1,532,760.25 per million inhabitants (95% CI 779,776.1-2,285,750.60). Sensitivity analyses confirmed the robustness of the results. CONCLUSIONS: The present simulation showed that ADEs could have a relevant economic impact on the Tuscan healthcare system. In this setting, the prevention of ADEs would result in important cost savings. These results could be likely extended to other healthcare systems. PMID- 30276631 TI - Fall-risk increasing drugs and prevalence of polypharmacy in older patients discharged from an Orthogeriatric Unit after a hip fracture. AB - BACKGROUND: Polypharmacy and fall-risk increasing drugs (FRIDS) have been associated with injurious falls. We aimed to estimate the prevalence of polypharmacy and FRIDS in older patients discharged from an Orthogeriatric Unit after a hip fracture surgery. METHODS: This study describes the baseline findings of a 2-year retrospective cohort study. We included patients older than 80 years discharged from an Orthogeriatric Unit who were able to walk before surgery. Patient's baseline variables, total number of drugs, and FRIDS at hospital discharge were collected. RESULTS: We included 228 patients. The mean number of drugs and FRIDS prescribed at discharge was 11.6 +/- 3.0 and 2.9 +/- 1.6, respectively. Polypharmacy was prevalent in all patients except in three: 23.3% (5-9 drugs) and 75.9% (>= 10 drugs). Only 11 patients had no FRIDS and 35.5% were on > 3 FRIDS. The most prevalent FRIDS were: agents acting on the renin angiotensin system (43.9%) and anxiolytics (39.9%). The number of FRIDS was higher in patients with extreme polypharmacy (3.4 +/- 1.5) than in those on 5-9 drugs (1.5 +/- 1.0, p < 0.05). Independent people in performing instrumental activities had lower risk of extreme polypharmacy (>= 10 drugs) or > 3 FRIDS: OR 0.39 (95% CI 0.18-0.83) and OR 0.41 (95% CI 0.20-0.84), respectively. People living in a nursing home had higher risk of > 3 FRIDS: OR 4.03 (95% CI 1.12 14.53). CONCLUSIONS: Polypharmacy and fall-risk increasing drugs are prevalent in patients discharged from orthogeriatric care after surgery for a hip fracture. Interventions on drug use at hospital discharge could have a potential impact on falls in this high-risk population. PMID- 30276632 TI - Year to year comparison of 2000-2015 in hip fracture management: same survival rate despite older and more fragile patients. AB - PURPOSE: The aim of this study was to compare clinical data, comorbidities and survival rates at 30 days and 1 year in two groups with femoral fractures, the first including patients admitted in 2000, and the other including patients admitted in 2015. The hypothesis of the study is that patients admitted in 2015 have more comorbidities and will therefore have a lower survival rate at 30 days and 1 year from trauma. METHODS: Patients admitted to the hospital with proximal femoral fractures in 2000 (90 patients) and 2015 (167 patients) were retrospectively reviewed. The following data were collected: age, gender, source of admission, ASA score, comorbidities, time from admission to surgery and length of hospital stay. The Charlson Comorbidity Index (CCI) score, a measure of comorbidity, and the Nottingham Hip Fracture Score (NHFS), a predictor of 30-day and 1-year mortality after hip fracture, were both calculated. RESULTS: Patients in the 2015 group were older and more institutionalized before fracture (p < 0.05), with a significant increase in Alzheimer's disease, chronic obstructive pulmonary disease, congestive heart failure and renal impairment. The length of stay was significantly lower in 2015. The NHFS and CCI were significantly higher in 2000. Mortality at 30 days and 1 year did not differ significantly in 2000 when compared to 2015. The CCI had the best predictive ability for mortality in both groups at 30 days and 1 year. CONCLUSIONS: The increase of comorbidities was not found to be correlated to increased mortality. This could be explained by enhanced patient management permitting earlier mobilization and weight bearing. PMID- 30276633 TI - Prevalence and related factors of office and home hypotension in older treated hypertensive patients. AB - BACKGROUND: Older hypertensive adults under treatment are especially susceptible to hypotensive episodes, which entail an elevated risk. However, data on this subject are very scarce. AIM: The purpose of this study was to determine the prevalence and predictors of office and home hypotension in older (>= 65 years) treated hypertensive adults. METHODS: Blood pressure (BP) was measured at the office and at home, using a validated oscillometric device. Office and home hypotension were defined as systolic BP (SBP) < 110 and/or diastolic BP (DBP) < 70 mmHg, and SBP < 105 and/or DBP < 65 mmHg, respectively. Masked hypotension was considered when office BP >= 110/70 and home BP < 105 and/or < 65 mmHg. We evaluated factors associated with hypotension both at the office and at home through multivariable models. RESULTS: The prevalence of hypotension among the 302 patients included in the study was 29.8% at the office and 23.9% at home, whereas the prevalence of masked hypotension was 10.4%. Older age, lower body mass index and use of calcium channel blockers were associated with office hypotension, while older age, diabetes and ischemic heart disease were predictors for home hypotension. CONCLUSION: Hypotension is frequent in older hypertensive adults under treatment. The presence of diabetes, ischemic heart disease and older age should alert for screening of hypotension at home to avoid overtreatment. PMID- 30276634 TI - Technical approach of robotic total right hepatic lobectomy: How we do it? AB - Despite advantages of minimally invasive surgery, many hepatobiliary surgeons are hesitant to offer this approach for major hepatic resection due to concerns of difficulty in liver manipulation, bleeding control, and suboptimal oncologic outcomes. The robotic surgical system has revolutionized the way traditional laparoscopic liver resection is undertaken. Limitations of traditional laparoscopy are being resolved by robotic technology. We aimed to describe aspects of minimally invasive liver surgery and our standardized technical approach. We discussed technical aspects of performing robotic total right hepatic lobectomy and described our standardized institutional method. A 79-year old man with an 11-cm biopsy-proven hepatocellular carcinoma was taken to the operating room for a robotic total right hepatic lobectomy. Past medical and surgical history was consistent with hypertension and diabetes mellitus. Robotic extrahepatic Glissonean pedicle approach was used to gain inflow vascular control. Right hepatic artery and portal vein were individually dissected and isolated prior to division. An intraoperative robotic ultrasound was utilized to guide liver parenchymal transection, securing negative margins. Robotic vessel sealing device was used as the main energy device during the parenchymal transection. Right hepatic vein was transected intrahepatically using a linear stapler. Operative time was 200 min without intraoperative complications. Estimated blood loss was 100 ml. Postsurgical recovery was uneventful and he was discharged home on postoperative day 4. Minimally invasive robotic total right hepatic lobectomy is feasible with excellent perioperative outcomes. PMID- 30276635 TI - Quality improvement as a population health promotion opportunity to reorient the healthcare system. AB - BACKGROUND: A quality improvement (QI) focus in systems strategically investing resources to achieve the Quadruple Aim (i.e., better population health, lower system costs, improved patient care, and an engaged and productive workforce) presents an opportunity to reorient health services towards population health promotion. SETTING: An interdisciplinary team linked across a large regionalized healthcare system engaged in a (Saskatoon) Region-wide 90-day QI initiative focused on patient safety. INTERVENTION: The team worked directly with healthcare teams to link cultural safety, patient-centeredness, and health equity to other dimensions of healthcare quality. The team provided data from health status reports, equity analyses of healthcare utilization, and stakeholder consultations and adapted QI methods, including A3 thinking and Plan-Do-Check-Act (PDCA) cycles. OUTCOMES: Throughout the 90 days, use of the terms "health equity" and "cultural safety" increased among healthcare teams and in region-wide communications. Within the year following the initiative, the Region made public and ongoing commitments to address health inequities. IMPLICATIONS: System-wide QI initiatives present opportunities to promote population health approaches, shift perspectives and language, and ultimately influence organizational culture. Learnings are relevant to health promotion practitioners attempting to engage healthcare partners, and for health systems strategically investing for improved population health. PMID- 30276636 TI - A modeling study exploring the impact of homelessness on rostered primary care utilization in Calgary, Canada. AB - OBJECTIVE: For patients who belonged to physician rosters at a family medicine practice in the core of Calgary, Canada, we compared primary care utilization for those who were stably housed and those experiencing homelessness. METHODS: This retrospective chart review accessed electronic medical record data for rostered patients who visited their family physician between July 1, 2015 and August 31, 2016. We assessed the association between homelessness status (defined as having been sheltered in overnight shelters and/or emergency/provisional housing during the study period) and the rate of visits to primary care (defined as the count of visits associated with a patient accounting for the length of the patient's relationship with their family physician) using multivariate negative binomial regression. RESULTS: We analyzed 1013 patients belonging to three family physician rosters, of whom 112 experienced homelessness during the study period (11.1%). The mean number of visits for patients who experienced homelessness was 9.6 (SD 10.5), compared to 4.2 (SD 3.6) visits for stably housed patients (p < 0.0001). The rate of accessing primary care for patients experiencing homelessness was 2.02 times greater than the rate for stably housed individuals (rate ratio [RR] 2.02, 95% confidence interval [95% CI] 1.74-2.35; p < 0.0001). CONCLUSION: In the context of an inner-city primary care clinic in Calgary, Canada, homelessness status is associated with an increased rate of visits to primary care. This work has implications for public health and health systems decision-makers involved in developing equitable health policy, as well as for frontline care providers who serve this vulnerable population. PMID- 30276637 TI - Differences in Injury Characteristics and Outcomes for American Indian/Alaska Native People Hospitalized with Traumatic Injuries: an Analysis of the National Trauma Data Bank. AB - OBJECTIVE: This study compares characteristics of American Indian/Alaska Natives (AI/AN) and non-Hispanic Whites (NHW) hospitalized for traumatic injury and examines the effect of race on hospital disposition. METHODS: Using 2007-2014 National Trauma Data Bank data, we described differences in demographic and injury characteristics between AI/AN (n = 39,656) and NHWs (n = 3,309,484) hospitalized with traumatic injuries. Multivariable regressions, adjusted for demographic and injury characteristics, compared in-hospital mortality and the risk of discharge to different dispositions (inpatient rehabilitation/long-term care facility, skilled nursing facility, home with home health services) rather than home between AI/AN and NHW patients. RESULTS: Compared to NHWs, a higher proportion of AI/ANs were age 19-44 (49% versus 27%) years and hospitalized with assault-related injuries (25% versus 5%). AI/ANs had lower odds of dying than NHWs during hospitalization (adjusted odds ratio (aOR) 0.72, 95% CI 0.63-0.84). However, AI/ANs also had lower odds than NHWs to discharge to locations with additional health services even after controlling for injury severity (inpatient rehabilitation/long-term care facilities aOR 0.79, 95% CI 0.67-0.93; skilled nursing facility aOR 0.70, 95% CI 0.49-0.98; home with home health services aOR 0.62, 95% CI 0.49-0.79). CONCLUSIONS: Injury patterns and acute hospitalization outcomes were significantly different for AI/ANs compared to NHWs. Injury prevention strategies targeting AI/ANs should reflect these differential injury patterns. Outcomes such as disability and access to rehabilitation services should be included when considering the burden of injury among AI/AN communities. PMID- 30276638 TI - Probabilistic retro-cues do not determine state in visual working memory. AB - The effective use of our capacity-limited visual working memory (VWM) requires mechanisms that govern how it represents information. Validly cueing an item in VWM after encoding, for instance, enhances memory performance for that item and biases its state in VWM, bringing its representation to an active state such that attentional selection is biased towards perceptually similar inputs. Critically, when the retro-cue is less than 100% valid (i.e., probabilistic rather than deterministic), the effect of the cue on memory performance varies. Here we investigated whether deterministic and probabilistic retro-cues also differ in their influence over item state in VWM. Participants encoded two colored squares, and a retro-cue indicated which item was most likely to be probed in a subsequent memory test. Across blocks, we manipulated cue validity to be deterministic (100% valid) or probabilistic (70% valid). On a subset of trials, no memory probe was presented and the trial ended with a visual search task in which a colored distractor -matching the cued memory item, the non-cued item, or neither - was presented. Predictably, in the deterministic condition, the presence of a singleton distractor matching the cued item reliably slowed reaction times during visual search. In the probabilistic condition, however, there were no differences in reaction times when the singleton matched the cued item or the non-cued item, despite a reliable benefit to memory performance on valid memory trials. We suggest that, while probabilistic retro-cues improve memory of the cued item, they are not sufficient to bias its state in VWM. PMID- 30276639 TI - Learning by Example: An International Perspective on Reflex-Testing for Lynch Syndrome. AB - BACKGROUND: Lynch syndrome (LS), an autosomal dominant cancer syndrome, is the most common cause of hereditary colon cancer. Currently, however, less than 5% of patients with LS have been identified. Reflex-testing programs (in which tumors of patients with colorectal cancer are routinely evaluated for LS) have been proposed for better identification of affected individuals, yet the uptake of these programs within health care systems is limited. This study explored the structure, implementation challenges, and future directions of existing international population-based reflex LS testing programs. METHODS: The study identified existing reflex-testing LS programs through the current literature and through a qualitative sampling approach. Key informants from each program were interviewed. Qualitative data were analyzed using a grounded theory analytic technique approach. RESULTS: The interviews were completed by 26 informants across seven identified programs. Three key themes were identified: (1) tension between a program imposed on stakeholders (a top-down approach) versus initiation of the program at the stakeholder level (bottom-up approach), (2) identification of pathologists as drivers of program success, and (3) strategies to optimize possible LS patients liaising with genetic counselors. Barriers to successful implementation included lack of stakeholder engagement and concerns regarding cost. Facilitators included strong administration to coordinate patient tracking and flexibility during the implementation process. CONCLUSIONS: Existing reflex testing LS programs have varying structures, standards, and protocols. Program design can have a direct effect on the uptake of genetic testing. These are important considerations in the large-scale planning of LS reflex-testing programs within health systems.

PMID- 30276641 TI - Are Staging Computed Tomography (CT) Scans of the Chest Necessary in Pancreatic Adenocarcinoma? AB - BACKGROUND: There is no consensus on the use of chest imaging in pancreatic ductal adenocarcinoma (PDAC) patients. Among PDAC patients, we examined the use of chest computed tomography (CT) over time and determined whether the use of chest CT led to a survival difference or change in management via identification of indeterminate lung nodules (ILNs). METHODS: Retrospective clinical data was collected for patients diagnosed with PDAC from 1998 to 2014. We examined the proportion of patients undergoing staging chest CT scan and those who had ILN, defined as >= 1 well-defined, noncalcified lung nodule(s) <= 1 cm in diameter. We determined time to overall survival (OS) using multivariate Cox regression. We also assessed changes in management of PDAC patients who later developed lung metastasis only. RESULTS: Of the 2710 patients diagnosed with PDAC, 632 (23%) had greater than one chest CT. Of those patients, 451 (71%) patients had ILNs, whereas 181 (29%) had no ILNs. There was no difference in median overall survival in patients without ILNs (16.4 [13.6, 19.0] months) versus those with ILN (14.8 [13.6, 15.8] months, P = 0.18). Examining patients who developed isolated lung metastases (3.3%), we found that staging chest CTs did not lead to changes in management of the primary abdominal tumor. CONCLUSIONS: Survival did not differ for PDAC patients with ILNs identified on staging chest CTs compared with those without ILNs. Furthermore, ILN identification did not lead to changes in management of the primary abdominal tumor, questioning the utility of staging chest CTs for PDAC patients. PMID- 30276642 TI - A New N Staging System for Colorectal Cancer in the Era of Extended Lymphadenectomy. AB - BACKGROUND: Complete mesocolic excision is becoming popular in colon cancer surgery in Western countries, and in the tumor-node-metastasis (TNM) classification of rectal cancer, a part of the lateral pelvic lymph nodes is classified as regional. However, the appropriateness of TNM staging according to the assessment of nodal status exclusively by extended lymphadenectomy remains unclear. PATIENTS AND METHODS: Using a nationwide multicenter database in Japan, we retrospectively analyzed 6866 patients with stage III colorectal cancer (CRC) treated with extended (D3) dissection. First, the best cutoff values for the number of metastatic nodes were explored. Second, the utility of the metastatic status of the main lymph nodes (i.e., at the origin of the feeding artery) and the lateral pelvic lymph nodes ("jN3" category in the Japanese staging system) as N staging criteria was evaluated. The modified N staging system that had the best risk stratification power was determined according to the Akaike information criterion (AIC). RESULTS: Excellent performance was noted when the number of metastatic nodes was categorized by cutoff values of "3/4" and "6/7." Categorization of nodal metastasis was proven the most clinically efficacious when classified as modified-N1 (N1 and jN3-negative), modified-N2a (N2a and jN3 negative), and modified-N2b (N2b and/or jN3-positive; AIC, 22,810.8), rather than the classification based on the TNM (AIC, 22,849.2) or Japanese staging system (AIC, 22,811.1). CONCLUSIONS: We structured a modified N staging system according to the number and extent of lymph node metastases. The modified system may be used in stage III cases for precise risk stratification.

PMID- 30276645 TI - Does p16+ Predict a Favorable Prognosis for Oropharyngeal Cancer? Risk Factors for Treatment Failure for Patients Who Underwent Surgery-Based Therapy. AB - BACKGROUND: This study aimed to identify prognostic clinicopathologic factors that could predict treatment failure and to analyze clinical data from p16+ oropharyngeal squamous cell carcinoma (OPSCC) patients who underwent surgery. METHODS: Data from p16+ OPSCC patients who underwent surgery at Severance Hospital of Yonsei University were retrospectively reviewed. RESULTS: The average smoking history was 14.6 pack-years (range 0-94 pack-years). Of the 188 patients, 73 (38.8%) underwent transoral robotic surgery (TORS) for surgical treatment of their primary lesions, and the remaining 115 patients (61.2%) underwent conventional surgery. Extracapsular nodal spread was detected in 87 patients (46.3%). At histologic examination, 67 patients (35.6%) showed positive surgical margins, and 121 patients (64.4%) had negative surgical margins. Postoperative adjuvant treatment was performed for 167 patients (88.8%). During the follow-up period, there were 18 recurrences including 2 local recurrences, 10 regional recurrences, and 6 distant metastases. During the study period, 17 deaths occurred. The univariate analysis showed that the American Joint Committee on Cancer (AJCC) 8th-edition staging system, lymphovascular invasion, more than four metastatic lymph nodes, and a smoking history of more than 10 pack-years were significantly associated with treatment failure. In the multivariate analysis, only the AJCC 8th-edition staging system was significantly associated with the patient's survival. CONCLUSION: Surgical treatment methods including TORS for p16+ OPSCC patients showed excellent oncologic results, and many previously known clinicopathologic factors did not show a significant relationship with patient prognosis. Only the newly revised AJCC 8th-edition staging system showed a significant relationship with patient survival, and this should be considered in the setting of p16+ OPSCC treatment guidelines in the future. PMID- 30276646 TI - Perioperative and Long-Term Outcomes of Laparoscopic Versus Open Lymphadenectomy for Biliary Tumors: A Propensity-Score-Based, Case-Matched Analysis. AB - BACKGROUND: The purpose of this study was to compare patients undergoing MILS and open liver resections with associated lymphadenectomy for biliary tumors (intrahepatic cholangiocarcinoma and gallbladder cancer) in a case-matched analysis using propensity scores. METHODS: A total of 104 consecutive patients underwent liver resection with associated locoregional lymphadenectomy by laparoscopic approach constituted the study group (MILS group). The MILS group was matched in a ratio of 1:2 with patients who had undergone open resection for primary biliary cancers (Open group). Short- and long-term outcomes were evaluated and compared, with specific focus on specific details of lymphadenectomy. RESULTS: Laparoscopic series resulted in a statistically significant lower blood loss (200 vs. 350, p = 0.03), minor intraoperative blood transfusions (3.2% vs. 7.9%, p = 0.04), and postoperative blood transfusions (10.5% vs. 15.8%), other than shorter length of stay (4 vs. 6 days, p = 0.04). Number of retrieved nodes was 8 versus 7 (p = not significant); particularly, percentage of patients who achieved the recommended AJCC cutoff of six lymph nodes harvested were 93.7% versus 85.8% (p = 0.05). Both overall and lymphadenectomy-related morbidity (bleeding, pancreatitis, lymphatic fistula, vascular, and biliary injuries) were lower in MILS group (respectively 16.3% and 3.2% vs. 22.1% and 5.3%, p = 0.03). Median disease-free survival was 33 versus 36 months and disease recurrence occurred in 45.3% versus 55.3% of patients in MILS and Open groups respectively. CONCLUSIONS: Laparoscopic approach for lymphadenectomy is a valid option in patients with biliary cancers, because it allows to maintain the advantages of minimally invasive approach, without compromising the accuracy and the outcomes of nodal dissection. PMID- 30276647 TI - Intraoperative Electron Radiation Therapy Combined with External Beam Radiation Therapy after Gross Total Resection in Extremity Soft Tissue Sarcoma: A European Pooled Analysis. AB - INTRODUCTION: We report a pooled analysis evaluating the combination of gross complete limb-sparing surgery, intraoperative electron radiation therapy (IOERT), and external beam radiation therapy (EBRT) in patients with extremity soft tissue sarcoma (STS). METHODS: Individual data of 259 patients (median follow-up 63 months) with extremity STS from three European expert centers were pooled. Median age was 55 years and median tumor size was 8 cm. Eighty percent of patients presented with primary disease, mainly located in the lower limb (81%). Union for International Cancer Control 7th edition stage at presentation was as follows: stage I: 9%; stage II: 47%; stage III: 39%; stage IV: 5%. Most patients showed high-grade lesions (91%), predominantly liposarcoma (31%). Median IOERT dose was 12 Gy, preceeded (17%) or followed (83%) by EBRT, with a median dose of 45 Gy. RESULTS: Surgery resulted in R0 resections in 71% of patients and R1 resections in 29% of patients. The 5-year local control (LC) rate was 86%, and significant factors in univariate analysis were disease status and resection margin. Only margin remained significant in multivariate analysis. The 5-year distant control rate was 69%, and significant factors in univariate analysis were histology, grading, resection margin, and metastases prior to/at IOERT. Only grading and metastases remained significant in multivariate analysis. Actuarial 5-year rates of freedom from treatment failure and OS were 61% and 78%, respectively. Significant factors for OS were grading and metastases prior to/at IOERT (univariate, multivariate). Limb preservation and good functional outcome were achieved in 95% and 81% of patients. CONCLUSIONS: Our pooled analysis confirmed prior reports of encouraging LC and survival, with excellent rates of preserved limb function with this treatment approach. Resection margin remained the most important factor for LC, while grading and metastases prior to/at IOERT mainly predicted survival.

AB - Oxalate nephropathy is associated with hereditary hyperoxaluria, Crohn disease, and previous gastric or intestinal surgery, especially in the setting of increased oxalate intake or ethylene glycol ingestion. We present a patient whose intake of vitamin C supplements (2 g/day), exacerbated by predisposing factors of prior small bowel obstruction and resection, and benign prostate hyperplasia (BPH), resulted in acute kidney injury due to oxalate nephropathy. We review past reports of vitamin C-induced oxalate nephropathy and discuss the underlying precipitating factors. PMID- 30276649 TI - Pre-eclampsia: the role of highly active antiretroviral therapy and immune markers. AB - PURPOSE OF THE REVIEW: This review highlights the role immune cells and markers such as natural killer (NK) cells, cytokines and human leukocyte antigen (HLA-G) play in predisposing HIV-infected women who are on HAART to develop PE, thus contributing to a better understanding and early diagnosis of PE with a subsequent reduction in maternal foetal and neonatal deaths. RECENT FINDINGS: Pregnant women infected with the Human Immunodeficiency Virus (HIV) have a 25% risk of mother to child transmission. This risk, however, decreases to 2% if the women is on treatment. Highly active antiretroviral therapy (HAART) is the recommended treatment for both pregnant and non-pregnant women infected with HIV. Treatment with HAART is reported to potentiate predisposition to the development of hypertensive disorders of pregnancy such as pre-eclampsia (PE). Pre-eclampsia accounts for 7-10% of abnormal pregnancies worldwide. Studies demonstrate that pregnant women with HIV have PE at lower frequencies than uninfected women, however, the converse is observed upon HAART initiation. HIV-infected women on HAART exhibit a greater tendency to develop PE, emanating from immune reconstitution induced by HAART. There is paucity of information as to the pathogenesis of PE upon HAART initiation and there are, therefore, controversial data as to whether HAART predisposes women to a lower, equal or higher risk of PE development compared to the general population, further investigations on the impact of HIV infection and HAART on the immune response and rate of PE development in HIV infected pregnant women are urgently needed. PMID- 30276650 TI - Atlanto-axial rotatory fixation complicating ventriculo-peritoneal shunt surgery: a case report and literature review. AB - INTRODUCTION: Atlanto-axial rotatory fixation (AARF) is a rare complication of ventriculo-peritoneal shunt (VPS) surgery. CASE PRESENTATION: The authors present a unique case of AARF developing early after VP shunting, with persistent torticollis, a "cock-robin" head position, and a thick fibrous band along the catheter path. Due to refractoriness to conservative treatments, AARF, which can be an early-onset complication of VPS surgery, was resolved by removing the distal catheter along with the fibrous band encasing it. CONCLUSION: Surgical removal of the fibrous band might be enough to solve such complication with no need of further surgical fusion procedures. PMID- 30276652 TI - Conservative and operative management of iatrogenic craniocerebral disproportion a case-based review. AB - INTRODUCTION: Craniocerebral disproportion (CCD) can occur as a sequela after shunting in early infancy. It can be understood as a disorder closely related to slit ventricle syndrome and chronic overdrainage syndrome. Here, we present two exemplary cases and summarize the pathophysiological, diagnostic, and therapeutic approaches to CCD. CLINICAL PRESENTATION: Two premature babies underwent shunting for posthemorrhagic hydrocephalus and presented in later childhood with recurrent episodes of symptomatic raised intracranial pressure (ICP) at 2 and 8 years of age, respectively. DIAGNOSIS AND MANAGEMENT: Both patients had unchanged ventricular size on cranial imaging and fulfilled the clinical diagnostic criteria of CCD. After confirming shunt patency, ICP monitoring was performed to diagnose intermittent intracranial hypertension. Different treatment pathways were pursued: While readjustment of a programmable shunt valve was sufficient to alleviate the raised ICP in the first case, a cranial expansion surgery was necessary in the second case. OUTCOME AND CONCLUSIONS: Both children were treated successfully after thorough assessment and careful choice of treatment approaches. This review provides detailed insight into CCD and highlights the importance of individual and critical decision-making in these complex patients. PMID- 30276651 TI - Cognitive functioning of pediatric patients with brain tumor: an investigation of the role of gender. AB - PURPOSE: The female gender has been considered a risk factor for cognitive impairment in pediatric brain tumor survivors. However, it is still unknown which specific cognitive domains are at greater risk of impairment in females. The aim of this study was to explore differences between male and female children in distinct domains of cognitive functioning, in order to deepen knowledge on the topic. METHODS: The cognitive performance of 100 males and 71 females aged 6-16 years was assessed by Wechsler Intelligence Scales for Children-Third Edition (WISC-III). Differences between males and females were tested not only on intellectual quotients, but also on WISC-III subtests, which allow the evaluation of different cognitive domains. Analyses were performed in the whole sample and dividing children based on the supratentorial vs. infratentorial location of the tumor. RESULTS: Gender was the only predictor of VIQ in the whole group and in children with supratentorial tumor. Female children with supratentorial tumor performed significantly worse than males in four out of six verbal subtests. However, even among children with infratentorial tumor, females performed worse than males on two verbal subtests. CONCLUSIONS: Overall, findings of this study suggest that females may have more difficulties than males at manipulating verbal oral material. A possible explanation of these findings could be that females present a greater vulnerability to white matter damage due to the illness and post-adjuvant therapies, in line with reports of the literature on female children with lymphoblastic leukemia.

(Copepoda: Cyclopoida: Octopicolidae), a new parasitic copepod of the octopuses Amphioctopus fangsiao (d'Orbigny) and Octopus minor (Sasaki) (Octopoda: Octopodidae) in the Yellow Sea. AB - A new species of parasitic copepod, Octopicola huanghaiensis n. sp., collected from the octopuses Amphioctopus fangsiao (d'Orbigny) and Octopus minor (Sasaki) (Octopoda: Octopodidae) in the Yellow Sea (off Qingdao, Shandong Province, China), is described. The new species is most similar to O. superba Humes, 1957, but can be distinguished from the latter by: (i) the third antennal segment having a different ornamentation; (ii) the fourth antennal segment of females much shorter than that in O. superba (49 vs 94 MUm); (iii) males much smaller than females (mean body length 1.3 vs 2.0 mm, respectively) (vs similar male and female body size in O. superba, 1.9 mm and 1.8 mm respectively); and (iv) the presence of a spike at the posterior tip of each labrum flap. Octopicola huanghaiensis n. sp. is the first species of Octopicola Humes, 1957 reported from A. fangsiao and O. minor and is the only species of the family Octopicolidae Humes & Boxshall, 1996 known in North Pacific waters. PMID- 30276654 TI - Burnout Among Physicians, Advanced Practice Clinicians and Staff in Smaller Primary Care Practices. AB - BACKGROUND: Burnout among primary care physicians, advanced practice clinicians (nurse practitioners and physician assistants [APCs]), and staff is common and associated with negative consequences for patient care, but the association of burnout with characteristics of primary care practices is unknown. OBJECTIVE: To examine the association between physician-, APC- and staff-reported burnout and specific structural, organizational, and contextual characteristics of smaller primary care practices. DESIGN: Cross-sectional analysis of survey data collected from 9/22/2015-6/19/2017. SETTING: Sample of smaller primary care practices in the USA participating in a national initiative focused on improving the delivery of cardiovascular preventive services. PARTICIPANTS: 10,284 physicians, APCs and staff from 1380 primary care practices. MAIN MEASURE: Burnout was assessed with a validated single-item measure. KEY RESULTS: Burnout was reported by 20.4% of respondents overall. In a multivariable analysis, burnout was slightly more common among physicians and APCs (physician vs. non-clinical staff, adjusted odds ratio [aOR] = 1.26; 95% confidence interval [CI], 1.05-1.49, APC vs. non-clinical staff, aOR = 1.34, 95% CI, 1.10-1.62). Other multivariable correlates of burnout included non-solo practice (2-5 physician/APCs vs. solo practice, aOR = 1.71; 95% CI, 1.35-2.16), health system affiliation (vs. physician/APC-owned practice, aOR = 1.42; 95%CI, 1.16-1.73), and Federally Qualified Health Center status (vs. physician/APC-owned practice, aOR = 1.36; 95%CI, 1.03-1.78). Neither the proportion of patients on Medicare or Medicaid, nor practice-level patient volume (patient visits per physician/APC per day) were significantly associated with burnout. In analyses stratified by professional category, practice size was not associated with burnout for APCs, and participation in an accountable care organization was associated with burnout for clinical and non-clinical staff. CONCLUSIONS: Burnout is prevalent among physicians, APCs, and staff in smaller primary care practices. Members of solo practices less commonly report burnout, while members of health system-owned practices and Federally Qualified Health Centers more commonly report burnout, suggesting that practice level autonomy may be a critical determinant of burnout. PMID- 30276656 TI - What I Would Do. PMID- 30276655 TI - Insurance Coverage Predicts Mortality in Patients Transferred Between Hospitals: a Cross-Sectional Study. AB - BACKGROUND: Patients transferred between hospitals are at high risk of adverse events and mortality. The relationship between insurance status, transfer practices, and outcomes has not been definitively characterized. OBJECTIVE: To identify the association between insurance coverage and mortality of patients transferred between hospitals. DESIGN: We conducted a single-institution observational study, and validated results using a national administrative database of inter-hospital transfers. SETTING: Three ICUs at an academic tertiary care center validated by a nationally representative sample of inter-hospital transfers. PATIENTS: The single-institution analysis included 652 consecutive patients transferred from 57 hospitals between 2011 and 2012. The administrative database included 353,018 patients transferred between 437 hospitals. MEASUREMENTS: Adjusted inpatient mortality and 24-h mortality, stratified by insurance status. RESULTS: Of 652 consecutive transfers to three ICUs, we observed that uninsured patients had higher adjusted inpatient mortality (OR 2.67, p = 0.021) when controlling for age, race, gender, Apache-II, and whether the patient was transferred from an ED. Uninsured were more likely to be transferred from ED (OR 2.3, p = 0.026), and earlier in their hospital course (3.9 vs 2.0 days, p = 0.002). Using an administrative dataset, we validated these observations, finding that the uninsured had higher adjusted inpatient mortality (OR 1.24, 95% CI 1.13-1.36, p < 0.001) and higher mortality within 24 h (OR 1.33 95% CI 1.11-1.60, p < 0.002). The increase in mortality was independent of patient demographics, referral patterns, or diagnoses. LIMITATIONS: This is an observational study where transfer appropriateness cannot be directly assessed. CONCLUSIONS: Uninsured patients are more likely to be transferred from an ED and have higher mortality. These data suggest factors that drive inter-hospital transfer of uninsured patients have the potential to exacerbate outcome disparities.

PMID- 30276658 TI - Job Negotiations in Academic Medicine: Building a Competency-Based Roadmap for Residents and Fellows. AB - Negotiation skills are critical to career success, yet many physicians feel ill equipped to negotiate for professional opportunities. Enhancing competencies in this arena may be especially critical for women and underrepresented minorities to reduce disparities in compensation and resources that begin upon entry into the workforce as junior faculty. This perspective offers a comprehensive overview of negotiation strategies and the job search process for individuals finishing medical training and seeking first-time employment. First, we extrapolate lessons from clinical medicine to provide a negotiation roadmap for residents and fellows. We use both a clinical and an employment scenario to illustrate the concept of principled negotiation in which negotiating partners elicit each other's values and interests and identify options for mutual gain. We then describe approaches to seeking and negotiating job opportunities and discuss typical timelines for these activities. We supply a list of professional needs to consider before a negotiation begins and introduce the concept of a best alternative to negotiated agreement to help ensure essential requirements are met in a final employment offer. Finally, we explore the utility of third-party assistance and published benchmarks and offer best practices for negotiating. PMID- 30276659 TI - Position paper of the Italian Society of Internal Medicine (SIMI) on prophylaxis and treatment of venous thromboembolism in patients with cancer. AB - Cancer patients are at high risk of developing thrombotic events, including venous thromboembolism (VTE) [deep venous thrombosis (DVT) and pulmonary embolism (PE)], and arterial thrombosis. DVT and PE represent the second leading cause of death in cancer patients; moreover, the development of thromboembolic events in cancer patients is linked to a greater need of hospitalization and frequency of side effects during treatment, in particular bleeding, and to an increased risk of recurrence during and following antithrombotic therapy. The thromboembolic risk may be different in different subgroups of cancer population, being highest in patients with metastatic disease, patients with pancreas, stomach, kidney or primary brain cancer, or during therapeutic interventions or surgery. This document focuses on several relevant topics including the epidemiology and pathogenesis of cancer-associated VTE, the current and future strategies of primary prevention and anticoagulant treatment, and the management of bleeding complications. The main literature data are discussed in detail, including, when available, evidence from randomized clinical trials and meta-analyses, international guidelines statements, the results of recently published trials comparing direct oral anticoagulants to low molecular weight heparin, and the design and aims of ongoing trials on prevention/treatment of cancer-associated VTE.

PMID- 30276661 TI - Red cell distribution width predicts mid-term prognosis in patients hospitalized with acute heart failure: the RDW in Acute Heart Failure (RE-AHF) study. AB - The aim of the study was to evaluate the prognostic role of red cell distribution width (RDW) in a broad population of patients hospitalized for acute heart failure (AHF). In a retrospective cohort observational study, 451 consecutive patients discharged for AHF were categorized in patients with low RDW (<= 14.8%) and high RDW (> 14.8%). The rates of death from all causes or of hospital readmission for worsening heart failure and death were determined after a median follow-up of 18 months. The overall population has a median age of 80 years (IQR 72-85), 235 patients (52%) were males. Patients with a higher RDW have more comorbidities and a higher Charlson Index. At follow-up, 200 patients (44%) had died and 247 (54%) had died or were readmitted for HF: in the cohort with low RDW, 70 patients (36.4%) had died, whereas in the cohort with high RDW, 165 patients (63.7%) had died: the unadjusted risk ratio of patients with high RDW was 2.03 (log-rank test: p < 0.0001). In a multivariate Cox regression model, the hazard ratio for death from any cause in the 'high RDW' cohort is 1.73 (95% confidence interval 1.2-2.48; p = 0.003); the RDW adds prognostic information beyond that provided by conventional predictors, including age; etiology of HF; anemia; hyponatremia; estimated glomerular filtration rate; NT-proBNP levels; Charlson comorbidity score, atrial fibrillation, functional status, therapy with renin-angiotensin-aldosterone system inhibitors, beta-blockers. RDW is a powerful marker of worse long-term outcomes in patients with AHF, and its prognostic value is maintained beyond that provided by other well-established risk factors or biomarkers. PMID- 30276662 TI - Myocyte Enhancer Factor 2c Regulates Dendritic Complexity and Connectivity of Cerebellar Purkinje Cells. AB - Mef2c haploinsufficiency is implicated in behavioral deficits related to autism, schizophrenia, and intellectual disability. Although perturbations in the cerebellum, notably Purkinje cells, have been linked to these neurological disorders, the underlying mechanisms remain poorly understood. In this study, we investigated the roles of Mef2c in cerebellar Purkinje cells during the first three weeks of postnatal development. Our analysis revealed that in comparison to other members of the Mef2 family, Mef2c expression is limited to postnatal Purkinje cells. Because the role of Mef2c has not been assessed in GABAergic neurons, we set out to determine the functional significance of Mef2c by knocking down the expression of Mef2c selectively in Purkinje cells. We found that the loss of Mef2c expression during the first and second postnatal week results in an increase in dendritic arborization without impact on the general growth and migration of Purkinje cells. The influence of Mef2c on dendritic arborization persists throughout the first three weeks, but is most prominent during the first postnatal week suggesting a critical period of Mef2c activity. Additionally, the loss of Mef2c expression results in an increase in the number of spines accompanied by an increase in Gad67 and vGluT1 puncta and decrease in vGluT2 puncta. Thus, our results reveal the specific expression and functional relevance of Mef2c in developing Purkinje cells and offer insight to how disruption of the expression of Mef2c in a GABAergic neuronal subtype may lead to pathogenesis of cerebellar-associated disorders. PMID- 30276663 TI - Evidence Supporting a Role for the Blood-Cerebrospinal Fluid Barrier Transporting Circulating Ghrelin into the Brain. AB - The stomach-derived hormone ghrelin mainly acts in the brain. Studies in mice have shown that the accessibility of ghrelin into the brain is limited and that it mainly takes place in some circumventricular organs, such as the median eminence. Notably, some known brain targets of ghrelin are distantly located from the circumventricular organs. Thus, we hypothesized that ghrelin could also access the brain via the blood-cerebrospinal fluid (CSF) barrier, which consists of the choroid plexus and the hypothalamic tanycytes. Using systemic injection of ghrelin or fluorescent-ghrelin in mice, we found that cells of the blood-CSF barrier internalize these molecules. In time-response studies, we found that peripherally injected fluorescent-ghrelin quickly reaches hypothalamic regions located in apposition to the median eminence and more slowly reaches the periventricular hypothalamic parenchyma, adjacent to the dorsal part of the third ventricle. Additionally, we found that CSF ghrelin levels increase after the systemic administration of ghrelin, and that central infusions of either an anti ghrelin antibody, which immuno-neutralizes CSF ghrelin, or a scrambled version of ghrelin, which is also internalized by cells of the blood-CSF barrier, partially impair the orexigenic effect of peripherally injected ghrelin. Thus, current evidence suggests that the blood-CSF barrier can transport circulating ghrelin into the brain, and that the access of ghrelin into the CSF is required for its full orexigenic effect. PMID- 30276664 TI - A Life Course Perspective on the Ways Older Men and Women Discuss Sexual Issues. AB - The present study examined how older adults communicate about sexual issues in light of the tremendous societal changes that have taken place with regard to sexuality in the past few decades. We relied on interviews with 47 Israelis 60 years of age and older who were instructed to discuss sexuality in old age and its unique characteristics, using semi-structured interviews. Analysis consisted of repeated comparisons and contrasts to identify common themes. A common thread of "secrets and lies" characterized the discussion of sexual issues throughout the life course of respondents. The findings showed that although older adults have been aware of the limited information provided to them during their upbringing and of the limited room allowed to sexuality in their emerging adulthood years, many have continued to find it difficult to address sexual issues, even in later life. Moreover, many perceived the information currently available about sexuality and the contemporary approach to sexuality brought by the media or their children and grandchildren as being somewhat inadequate. Implications for practice are discussed. PMID- 30276665 TI - Cochlear hair cell densities in the rabbit. AB - A typical cochleogram was plotted to investigate hair cell densities as a percentage along the whole length of the basilar membrane (BM) of the rabbit, the length of the BM and the width of the organ of Corti. We generated surface preparations of cochlea from adult, healthy New Zealand White (NZW) rabbits. The numbers of inner hair cells (IHCs) and outer hair cells (OHCs) were counted from images acquired from a digital camera attached to an Olympus light microscope with a scale of 100 MUm as a primary unit drawn continuously, and the numbers of IHCs and OHCs were converted to densities at 10% intervals along the length of the cochlea. Meanwhile, the length of the BM and the width of the organ of Corti were calculated. The average length of the cochlea was 14.504 +/- 0.403 mm, while the total number of IHCs and the numbers of OHCs in the first, second, and third rows were 1556 +/- 13, 1840 +/- 47, 1842 +/- 46, and 1840 +/- 45, respectively, accounting for 21.98%, 26.00%, 26.02%, and 26.00% of the total number of cells, respectively. The densities of each row of OHCs reported in 10% intervals were greater than the densities of the IHCs corresponding to their anatomical locations within the cochlea. The densities of OHCs in each row were distributed uniformly along the BM, while the IHCs densities were not and showed a bimodal distribution with a maximum density at the apex and at 70-80% of the cochlear length from the apex but a lower density in the remaining cochlea. The width of the organ of Corti decreased successively from the apex to the base. PMID- 30276666 TI - Formulation and evaluation of carrier-free dry powder inhaler containing sildenafil. AB - Pulmonary delivery of sildenafil for the treatment of pulmonary arterial hypertension could overcome the limitations of intravenous and oral administration routes, such as poor patient compliance and systemic side effects. In this study, a carrier-free dry powder inhaler (DPI) formulation was developed, using spray drying technique and L-leucine as a dispersibility enhancer. Sildenafil citrate salt and sildenafil free base were evaluated for drug transport using a Calu-3 cell model, and their suitability for DPI production by spray drying was tested. Characteristics of the resultant carrier-free DPI powders were examined, namely crystallinity, morphology, size distribution, density, zeta potential, and aerodynamic performance. A Box-Behnken design was adopted to optimize the formulation and process conditions, including leucine amount, fraction of methanol in spraying solvent, and inlet temperature. While both sildenafil forms exhibited sufficient permeability for lung absorption, only sildenafil base resulted in DPI powders which were stable for 6 months. The introduction of leucine into the formulations effectively enhanced aerodynamic performance of the powders and particles with favorable size, shape, and density were produced. The optimal DPI formulation determined from experimental design possesses excellent aerodynamic performance with 89.39% emitted dose and 80.08% fine particle fraction, indicating the possibility of incorporating sildenafil into carrier-free DPIs for pulmonary delivery. PMID- 30276667 TI - Promises and Pitfalls of Using Digital Traces for Demographic Research. AB - The digital traces that we leave online are increasingly fruitful sources of data for social scientists, including those interested in demographic research. The collection and use of digital data also presents numerous statistical, computational, and ethical challenges, motivating the development of new research approaches to address these burgeoning issues. In this article, we argue that researchers with formal training in demography-those who have a history of developing innovative approaches to using challenging data-are well positioned to contribute to this area of work. We discuss the benefits and challenges of using digital trace data for social and demographic research, and we review examples of current demographic literature that creatively use digital trace data to study processes related to fertility, mortality, and migration. Focusing on Facebook data for advertisers-a novel "digital census" that has largely been untapped by demographers-we provide illustrative and empirical examples of how demographic researchers can manage issues such as bias and representation when using digital trace data. We conclude by offering our perspective on the road ahead regarding demography and its role in the data revolution.

PMID- 30276668 TI - Computed tomography coronary angiography in patients without known coronary artery disease can demonstrate possible non-cardiovascular causes of non-acute retrosternal chest pain. AB - OBJECTIVES: To assess the computed tomography coronary angiography (CTCA) accuracy for demonstrating possible non-cardiovascular causes of non-acute retrosternal chest pain in patients without known coronary artery disease (CAD) and to correlate CTCA results with the patient management and relief from pain. METHODS: This prospective observational study was approved by the ethical committee. Consecutive patients suffering non-acute chest pain who underwent CTCA and with not known CAD were enrolled and classified as having coronary diseases (CD) or extracardiac diseases (ECD). Association between age, sex, body mass index (BMI), cardiovascular risk factors, and type of chest pain with CD or ECD was estimated. Correlation between BMI classes and each risk factor was also calculated. RESULTS: A total of 106 patients (60 males; age 62 +/- 14 years [mean +/- standard deviation]; mean BMI 27) were enrolled. Hypertension was found in 71/106 (67%); smoking was significantly more frequent among males (p = 0.003) and hypercholesterolemia among females (p = 0.017); hypertension and hypercholesterolemia significantly correlated with age, and hypertension also with BMI. Pain was atypical in 70/106 (66%) patients. The kind of pain did not correlate with disease or gender. CTCA showed possible causes of chest pain in 69/106 (65%) patients; 32/69 (47%) having only CD, 23/69 (33%) only ECD, and 14/69 (20%) both CD and ECD. Prevalence was: hiatal hernia 35/106 (33%); significant CAD 24/106 (23%); myocardial bridging 22/106 (21%). At follow-up of 94/106 (89%) patients, 71/94 (76%) were pain-free, 14/17 (82%) significant CAD had been treated, and only one patient with non-significant CAD was treated after CTCA. CONCLUSION: CTCA suggested possible causes of non-acute pain in 65% of patients. MAIN MESSAGES: * CTCA can either rule in or rule out possible causes of chest pain alternative to CAD. * Clinically relevant findings were detected in 65% of patients with non-acute chest pain. * Non-cardiovascular diseases potentially explained symptoms in 35% of patients. PMID- 30276670 TI - Clinical and genetic characteristics of familial hypercholesterolemia patients with type 2 diabetes. AB - PURPOSE: Though type 2 diabetes mellitus (T2DM) is an important and independent risk factor for coronary artery disease (CAD) in the general population, the impact of T2DM on CAD in patients with familial hypercholesterolemia (FH) is less understood. Thus, the current study aimed to examine the features of FH patients with T2DM and explore the effects of T2DM on CAD in FH. METHODS: A total of 289 clinical heterozygous FH (HeFH) patients diagnosed with Dutch Lipid Clinic Criteria were consecutively recruited and divided into a T2DM group (n = 58) and non-T2DM group (n = 231). Clinical characteristics and laboratory findings were compared between the two groups. Target exome sequencing was used for gene mutation analysis. RESULTS: HeFH patients with T2DM had significantly higher levels of triglycerides, body mass index and free fatty acids than did non-T2DM patients; moreover, patients with T2DM more frequently exhibited hypertension. However, the spectrum of FH-causing mutations was not significantly different (p = 0.061). Notably, patients with T2DM had higher prevalence of CAD (p = 0.012) and higher Gensini Score (p = 0.002). The regression analysis confirmed that HbA1c was an independent risk factor for both the presence and severity of CAD [OR 2.321 (1.098-4.904), p = 0.027; OR 1.349 (1.032-1.762), p = 0.028, respectively] in patients with HeFH. CONCLUSIONS: Although there were not many differences in the clinical, lipid and genetic aspects of HeFH patients with and without T2DM, T2DM and HbA1c were associated with worse coronary lesions, suggesting that diabetes and the degree of blood glucose control are also important determinants of cardiovascular disease in these patients. PMID- 30276671 TI - Lessons learned from a student-driven initiative to design and implement an Organ and Tissue Donation course across Canadian medical schools. AB - The competencies required of the well-trained physician are constantly evolving, and medical education must adapt accordingly. In response, a growing number of influential medical education licensing and accreditation bodies have proposed frameworks that outline society's expectations of physician competencies. In Canada, undergraduate and graduate curricula have undergone major changes to meet the specifications of the CanMEDS framework, and similar efforts are underway internationally. Nonetheless, ensuring the values enshrined within such frameworks become integral to a physician's identity remains challenging. We believe that student-led curricular initiatives represent a novel way of approaching this shifting medical education landscape.In this article, we reflect on lessons we learned as medical students spearheading an initiative to change how organ and tissue donation is taught in Canadian medical schools. Citing relevant medical education literature where applicable, we include a detailed description of our approach as a roadmap for students contemplating their own curricular innovations. By outlining the factors influencing this project's implementation, as well as the benefits and limitations of student participation in curriculum reform, we offer educators a fresh perspective on optimizing the student role in this important process. Ultimately, the authors argue that not only can student participation render curricular content more accessible to learners, but that the responsibilities students take on in this role naturally lead to the development of CanMEDs-based competencies such as advocacy, scholarship, and inter-professionalism. PMID- 30276672 TI - How accurate and precise are CT based measurements of iodine concentration? A comparison of the minimum detectable concentration difference among single source and dual source dual energy CT in a phantom study. AB - OBJECTIVES: To assess the impact of scan- and patient-related factors on the error and the minimum detectable difference in iodine concentration among different generations of single-source (SS) fast kV-switching and dual-source (DS) dual-energy CT (DECT). METHODS: Lesions having eight different iodine concentrations (0.2-4 mgI/mL) were emulated in a 3D-printed phantom of medium and large size. Each combination of concentration and size was scanned in dual-energy mode on four different SS and DS DECTs. Radiation doses were 7 and 10 mGy (medium size) and 10, 13, and 16 mGy (large size). Iodine maps were reconstructed with filtered back projection (FBP) and vendor-specific iterative reconstruction algorithms (IRs). Absolute error of iodine quantification (E) was measured. Multivariate regression models determined the influence of CT scanner, iodine concentration, phantom size, radiation dose, and reconstruction algorithm on E. The minimum detectable difference in iodine concentration (ICmin) under the same imaging conditions (intra-conditional) and among different imaging conditions (inter-conditional) was calculated. RESULTS: The error was significantly lower in current than in previous DECT generations (p < 0.001). For all CT scanner conditions, the error was significantly higher with increasing phantom size and decreasing radiation dose (p < 0.001). Iodine concentration only significantly affected the error for SS DECT (p < 0.001). ICmin depended on patient- and scan related factors and ranged from 0.4 to 1.5 mgI/mL. CONCLUSIONS: Patient- and scan related factors have a significant impact on the error and minimum detectable difference in iodine concentration within and among SS fast kV-switching and DS DECT. KEY POINTS: * Patient- and scan-related factors have a significant impact on the error and minimum detectable difference in dual-energy CT-based iodine quantification. * Third-generation DECTs outperformed second-generation scanners for both single-source and dual-source dual-energy CT. * The minimum intra- and inter-conditional detectable difference in iodine concentration ranged from 0.4 to 1.5 mg iodine/mL. PMID- 30276673 TI - Quantitative susceptibility mapping in the human fetus to measure blood oxygenation in the superior sagittal sinus. AB - OBJECTIVES: To present the feasibility of performing quantitative susceptibility mapping (QSM) in the human fetus to evaluate the oxygenation (SvO2) of cerebral venous blood in vivo. METHODS: Susceptibility weighted imaging (SWI) data were acquired from healthy pregnant subjects (n = 21, median = 31.3 weeks, interquartile range = 8.8 weeks). The susceptibility maps were generated from the SWI-phase images using a modified QSM processing pipeline, optimised for fetal applications. The processing pipeline is as follows: (1) mild high-pass filtering followed by quadratic fitting of the phase images to eliminate background phase variations; (2) manual creation of a fetal brain mask that includes the superior sagittal sinus (SSS); (3) inverse filtering of the resultant masked phase images using a truncated k-space approach with geometric constraint. Further, the magnetic susceptibility, ?chiv and corresponding putative SvO2 of the SSS were quantified from the generated susceptibility maps. Systematic error in the measured SvO2 due to the modified pipeline was also studied through simulations. RESULTS: Simulations showed that the systematic error in SvO2 when using a mask that includes a minimum of 5 voxels around the SSS and five slices remains < 3% for different orientations of the vessel relative to the main magnetic field. The average ?chiv in the SSS quantified across all gestations was 0.42 +/- 0.03 ppm. Based on ?chiv, the average putative SvO2 in the SSS across all fetuses was 67% +/- 7%, which is in good agreement with published studies. CONCLUSIONS: This in vivo study demonstrates the feasibility of using QSM in the human fetal brain to estimate ?chiv and SvO2. KEY POINTS: * A modified quantitative susceptibility mapping (QSM) processing pipeline is tested and presented for the human fetus. * QSM is feasible in the human fetus for measuring magnetic susceptibility and oxygenation of venous blood in vivo. * Blood magnetic susceptibility values from MR susceptometry and QSM agree with each other in the human fetus. PMID- 30276674 TI - Absence of potential gadolinium toxicity symptoms following 22,897 gadoteric acid (Dotarem(r)) examinations, including 3,209 performed on renally insufficient individuals. AB - OBJECTIVES: Recent safety concerns regarding gadolinium-based contrast agents (GdCAs) concluded with the suspension of some agents from the European market, yet a clinical consequence remains unknown. We used electronic health records to investigate the incidence of potential toxicity to gadoteric acid (Dotarem(r)) within our local population, including those with renal insufficiency (RI). METHODS: Data for patients who underwent contrast-enhanced MRI were identified, stratified by renal function at time of scan and retrospectively followed using routinely collected health data. Searches performed were: records of hypersensitivity reactions; diagnoses of nephrogenic systemic fibrosis (NSF); onset of chronic pain, a symptom that has been associated with NSF and the theorised gadolinium deposition disease (GDD); and post-contrast acute kidney injury (PC-AKI). Comparisons were made between patients and controls (those who underwent non-contrast scans) via chi-square and ANOVA statistical tests. RESULTS: Of the 22,897 contrast-enhanced MRI scans performed locally from 2004 2016 (adult, n = 22,325 and paediatric, n = 572), 14% were performed on patients with RI (30 <= eGFR < 60, n = 2,622; 15 <= eGFR < 30, n = 464; eGFR < 15, n = 123). Two adult patients (0.01%) suffered hypersensitivity reactions. Zero cases of NSF were reported, with an average follow-up time of 6.0 +/- 2.5 years (range, 8 months-15 years). Analysis failed to highlight statistically higher rates of chronic pain onset post-MRI (adult: p = 0.777, paediatric: p = 0.578), or PC-AKI (adult: p = 0.566, paediatric: p = 0.841), in the patient groups compared to controls. CONCLUSIONS: These data indicate that administration of gadoteric acid to RI patients does not result in a higher rate of signs or symptoms that may be associated with gadolinium toxicity when compared to controls. KEY POINTS: * Following 22,897 administrations of gadoteric acid to a local population, there was no association with symptoms that may be associated with gadolinium toxicity. * Zero cases of nephrogenic systemic fibrosis were reported following 3,209 gadoteric acid administrations to a cohort of renally insufficient patients. * A low number of hypersensitivity reactions were observed (0.01%) and no higher rate of chronic pain or post-contrast acute kidney injury were noted when compared with a control cohort of non-contrast-enhanced examinations. PMID- 30276675 TI - The value of post-mortem computed tomography of burned victims in a forensic setting. AB - OBJECTIVES: Fire deaths are challenging fatalities for forensic pathologists, as the main question of whether death was due to the fire or not needs to be answered. In this retrospective study, we assessed whether post-mortem computed tomography (PMCT) has an added value prior to a forensic autopsy of burned victims. METHODS: From 2008 to 2016, a PMCT was performed in 50 burned corpses prior to a complete forensic autopsy. In retrospect, all 50 PMCT scans were systematically assessed by a forensically experienced radiologist, masked from the autopsy reports. Subsequently, the PMCT findings were compared with the autopsy reports. RESULTS: Heat fractures, contractions and destruction of extremities, subcutaneous emphysema and post-mortem gas collections were easier to detect by PMCT compared to autopsy. Alterations by penetrating and blunt trauma and the presence of foreign bodies were easy to detect by PMCT as well by autopsy. PMCT was, however, not successful in detecting signs of vitality during the fire, detection of superficial thermal injuries and to answer the main question of the forensic autopsy, which is to investigate the cause of death. CONCLUSIONS: PMCT prior to autopsy is a valuable add-on in the post-mortem forensic investigation of burned victims for detection of hidden signs of trauma, gas collections and foreign bodies. However, since PMCT cannot answer the two main questions in forensic examination-determining the cause of death and detecting signs of vitality during the fire-it cannot replace an autopsy. KEY POINTS: * Post-mortem CT (PMCT) in burned victims shows hidden signs of trauma. * Foreign bodies and gas collections can easily be detected. * Cause of death and vitality signs cannot be assessed by PMCT. PMID- 30276676 TI - Microvascular characteristics of lower-grade diffuse gliomas: investigating vessel size imaging for differentiating grades and subtypes. AB - OBJECTIVES: Vessel size imaging (VSI) could reveal average microvessel diameter. The aim was to investigate microvascular characteristics and the efficacy of VSI in lower-grade glioma (LGG) grading and subtype differentiation based on 2016 classification of central nervous system tumours. METHODS: Fifty-seven LGG (grade II/III, 36/21) patients who received VSI examination before surgery were retrospectively analysed. The average (Rmean) and maximum (Rmax) vessel size indexes were obtained. The long (VDmax) and short (VDmin) vascular diameter, microvascular area (MVA) and density (MVD) were obtained using paraffin specimens. The patients were divided into grades II and III, and histological and molecular subtypes. The differences among microvascular parameters of different subtypes and grades were compared. Two-sample t-test, analysis of variance test, Mann-Whitney test, the Kruskal-Wallis test and Pearson correlation analysis were used for statistics. RESULTS: Rmean, Rmax, VDmin, VDmax, and MVA were higher in grade-III than in grade-II LGGs (p < 0.05) in each type except the isocitrate dehydrogenase (IDH) mutant with 1p/19q-intact type. For grade II, the IDH mutant with 1p/19q co-deleted and IDH wildtype possessed more dominant angiogenesis than IDH mutant with 1p/19q-intact type, revealed by lower Rmean, Rmax and VDmin while higher MVD for the former (p < 0.05), the same as oligodendroglioma versus astrocytoma. Rmean and Rmax correlated with VDmin (r = 0.804, 0.815, p < 0.05), VDmax (r = 0.766, 0.774, p < 0.05) and MVA (r = 0.755, 0.759, p < 0.05), respectively, while they had no correlation with MVD (r = -0.085, -0.080, p > 0.05). CONCLUSIONS: VSI holds great potential for non-invasively revealing microvascular characteristics of LGGs pre-surgery and differentiating their grades and molecular subtypes. KEY POINTS: * VSI can assist in differentiating grade-II and -III gliomas. * The IDH gene and 1p/19q chromosome may influence the angiogenesis in grade-II gliomas. * VSI is valuable for differentiating the molecular subtypes of grade-II gliomas. PMID- 30276677 TI - Enhanced expression of nidogen 1 around the nest of basal cell carcinoma compared with that around squamous cell carcinoma. AB - Basal cell carcinoma (BCC) is a malignant skin tumor originating from cells of the epidermal basal layer and adnexal epithelium, especially in sun-exposed areas. Unlike squamous cell carcinoma (SCC), BCC has a propensity to grow only locally possibly due to differences in the surrounding microenvironment including the basement membrane (BM) and stroma. To investigate the components constituting the BM and surrounding connective tissue in BCC and SCC, we analyzed the expression of BM proteins, nidogen 1 (NID1) and type IV collagen (COL4). We compared the immunohistochemical expressions of NID1 and COL4 among tumor specimens from BCC, SCC and its precancerous condition, actinic keratosis (AK), (n = 5 each condition). The expressions of NID1 and COL4 were both decreased around the tumor nest of SCC. In contrast, the expressions of both NID1 and COL4 around the nest of BCC were much higher than in the peri-lesional normal skin not only at the BM, but also in the surrounding stromal tissue. Our findings imply that the surrounding stromal cells of BCC, but not SCC or AK, excessively produce NID1 and COL4, which may be involved in preventing BCC cells from destroying the BM and invading the dermis.

AB - The aim of this study was to examine the biogas production and the adsorption aspect of microorganism from different coals. Coal samples were obtained from Qianqiu mine and Guandi mine. Microbial populations were cultured from the coal mine drainage. After an anaerobic reaction period at about 35 degrees C, adsorption rate was determined by the spectrophotometer, while a scanning electron microscopy was used to observe the microorganisms on the coal and the headspace methane was analyzed using gas chromatography. Results show that the coal rank and particle size serve as important factors influencing the adsorption of microorganism and biogenic methane production. With decreasing particle size, the Qianqiu coal produced a considerable adsorption rate between 75 and 79%, while the adsorption rate of Guandi coal was between 52 and 74%. Meanwhile, the density of microorganisms from the Qianqiu coal surface demonstrated a higher level of adsorption than that of Guandi coal following the scanning electron microscopy images. Additionally, Qianqiu coal produced a higher level of biogas production (391.766-629.199 MUmol/g) than that of Guandi coal (292.835-393.744 MUmol/g) and the Qianqiu coal also generated a higher concentration of methane during the incubation. When the adsorption rate decreasing, the biogas production from various pulverized coals appeared to be decreased and demonstrated a positive correlation to the adsorption rate. The results of this study suggest that the adsorption behavior of microorganisms is closely related to the effect of coal biodegradation and contributes to the biogenic methane production potential.

AB - The aim of this study is to search the role of tourism development in the environmental quality for the major tourist destination countries. Ecological footprint has been selected as a proxy of environmental quality with this respect while top 10 tourist countries have been selected as samples of the study. Panel estimation results of this study show that the tourism-induced environmental Kuznets curve has been confirmed for these tourist countries which has an inverted U-shape. Tourism development in the selected countries exerts negatively significant effects on the levels of ecological footprints. Thus, this study concludes that tourism development in top tourist countries exert improving effect on the levels of environmental quality. PMID- 30276682 TI - Transformation of the chemical composition of surface waters in the area of the exploited Lomonosov diamond deposit (NW Russia). AB - The specific objective of this study was to investigate the changes in the chemical composition of river waters during the exploitation of the Lomonosov diamond deposit and the danger of these changes for the ichthyofauna. It was found that the Ca-HCO3 composition of river water both upstream and downstream from the quarry was almost identical before discharge of the drainage waters into the river. In subsequent years, the water downstream from the quarry acquired a Na-HCO3 composition, and then a Na-HCO3-Cl composition and TDS increased by 2.5 times. With respect to Fe, Mn, and Mo, concentrations that are above the maximum permissible concentrations (MPCs) for fishery rivers are apparent. At the same time, elevated Fe and Mn concentrations are associated with the natural composition of river water. The negative influence of drainage waters is manifested only with respect to the high concentrations of Mo. An important role in increasing Mo concentrations in drainage waters is played by the processes of hydrolysis of sodium aluminosilicates and mixing of fresh water with salt water. The concentrations of Sr, B, Ba, V, and Cr in drainage waters are higher than those in surface waters. However, they generally do not exceed the concentrations of the current MPCs. The source of Cr, Ba, Ni, and V in the drainage waters can be the products of the kimberlite magmatism. The possible impacts of metals effects on fish are presented. PMID- 30276680 TI - Oxidative stress, energy metabolism and molecular responses of earthworms (Eisenia fetida) exposed to low-density polyethylene microplastics. AB - Soils are both a sink and a pathway of plastic wastes, but there is a great lack of knowledge regarding their impacts on soil biota. To tackle the mechanisms of toxicity of these contaminants to soil invertebrates, earthworms (Eisenia fetida Savigny, 1826) were exposed during 28 days to different concentrations of low density polyethylene microplastics (62, 125, 250, 500 and 1000 mg MPs kg-1 soildw) with sizes ranging between 250 and 1000 MUm, in an artificial soil. The ecotoxicological responses were evaluated by analysing various oxidative stress biomarkers (catalase, glutathione S-transferase and thiobarbituric acid reactive substances), a biomarker of energy metabolism (lactate dehydrogenase) and overall organism molecular changes by Fourier transform infrared spectrometry (FTIR) and nuclear magnetic resonance (NMR) analyses. Significant effects resulting from an unbalanced oxidative stress system, expressed in terms of thiobarbituric acid reactive substances levels were recorded on earthworms exposed at the three highest concentrations tested. Despite that, no significant changes were recorded on the molecular profiles of earthworms by FTIR-ATR. NMR analysis pointed out for differences from the control, only for earthworms exposed to the lowest concentration of MPs. Considering that stress responses are complex, and involve multiple mechanisms, a cluster analysis taking into account all the parameters assessed, clearly identified two groups of earthworms separated by the concentration of 250 mg MPs kg-1 soildw, above each meaningful effects were recorded. PMID- 30276683 TI - Ultrasonic seed treatment improved physiological and yield traits of rice under lead toxicity. AB - Lead (Pb) is a highly toxic metal that damages normal plant metabolism and often results in reduced crop growth and yield. To measure whether or not ultrasonic seed (US) treatment alleviates Pb stress in rice, the seeds of two rice cultivars, i.e., Guangyan1 and Huahang31, were exposed to 30 min of ultrasonic vibration and then the seedlings were transplanted to Pb-contaminated soil. Results revealed that the Pb contents in roots, stems, leaves, panicles (at heading), and brown rice (at maturity) were lower in US treatment than control (CK; without US treatment); the trend for accumulation of Pb in different plant parts was recorded as: root ? stems ? leaves ? panicles ? brown rice in both rice cultivars. Overall, the Pb contents in the brown rice of Huahang31 were higher than those in Guangyan1. Moreover, the contents of proline and soluble protein as well as the activities of superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) were significantly higher while the malondialdehyde (MDA) contents were significantly reduced in US treatment compared to CK. The effective panicle number, seed set percentage, grains per panicle, 1000-grain weight, and grain yield were increased by 8.9%, 5.3%, 6.8%, 4.4%, and 26.6% in Guangyan1 and 3.2%, 5.7%, 5.7%, 5.0%, and 24.2% in Huahang31, respectively in US treatment compared to CK. Hence, seed treatment with ultrasonic waves could improve rice performance and reduce brown rice Pb accumulation under Pb-polluted soils. PMID- 30276684 TI - Protective potential of Opuntia microdasys flower decoction on fructose-alloxan induced diabetic rats on kidney and pancreas: chemical and immunohistochemical analyses. AB - Diabetes is a serious condition that is linked to the development of oxidative stress causing among many other effects, kidney failure and pancreatic disorders. However, traditional plant-based remedies can be considered an alternative to diabetes healing. In this context, this study was oriented towards evaluating the protective effect of the flowers of Opuntia microdasys Lehm. collected in Tunisia at a biochemical and histological level on kidneys and pancreas of a type 2 diabetic rats. Renal and pancreatic toxicities were induced in diabetic male Wistar rats by fructose alloxan. Diabetic rats were treated with an extract obtained from flowers collected at post-flowering stage (OFP) (100 and 200 mg kg 1 bw) and metformin (100 mg kg-1 bw) for 28 days. Oral administration of OFP at 200 mg kg-1 bw showed significant reduction of the uric acid, urea, creatinine, amylase, lipase, and glycated hemoglobin (HbAlc). The levels of SOD, CAT, and GPx were increased, while protein carbonyls and lipid peroxidation TBARS levels were reduced in the kidney and pancreas. The altered kidney and pancreas histology were restored in rats treated with OFP. Thus, the present study demonstrated that OFP has antihyperglycemic activity in fructose-alloxan-induced diabetic rats. PMID- 30276686 TI - Response of Tradescantia plants to oxidative stress induced by heavy metal pollution of soils from industrial areas. AB - Numerous investigations have demonstrated that even soil in which concentrations of individual elements do not exceed permissible limits can cause harmful effects in living organisms. In the present study, polluted-soil-induced oxidative stress was evaluated using Tradescantia clone 4430, which is widely used for genotoxicity evaluations, employing biochemical (superoxide dismutase (SOD), contents of ascorbic acid (AA), carotenoids (Car), hydrogen peroxide (H2O2), chlorophyll (Chl) a/b ratio), and molecular (RAPD and differential display (DD PCR)) markers after long-term exposure. The activity (staining intensity) of SOD isoforms in Tradescantia leaves was higher in plants grown in all heavy-metal polluted test soils compared to the control. No direct link between the soil pollution category and the contents of AA, Car, Chl a/b in Tradescantia leaves was revealed, but the concentration of H2O2 was shown to be a sensitive biochemical indicator that may appropriately reflect the soil contamination level. Both short-term (treatment of cuttings with H2O extracts of soil) and long term (0.5 and 1.0 year) exposure increased MN frequencies, but the coincidence of the MN induction and the soil pollution level was observed only in some cases of long-term exposure. Soil (geno)toxin-induced polymorphism in the RAPD profile was determined with two primers in plants after long-term exposure to soils of an extremely hazard category. Transcript profiling of plants after long-term cultivation in test soils using DD-PCR showed that the majority of differentially expressed transcript-derived fragments (TDFs) were homologous to genes directly or indirectly participating in photosynthesis, the abiotic stress response, and signal transduction cascades. PMID- 30276685 TI - Differential transcriptional changes in human alveolar epithelial A549 cells exposed to airborne PM2.5 collected from Shanghai, China. AB - Fine particulate matters (PM2.5) are the core pollutants of haze episode, which pose a serious threat to the human health of developing countries. However, the mechanisms involved in PM2.5-induced hazard influence are not to fully elucidated. In the present study, human lung epithelial cells (A549) were exposed to various concentrations of PM2.5 samples collected from Shanghai, China. Illumina RNA-Seq method with transcriptome, Gene Ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were further employed to identify the detrimental effects of PM2.5 on A549 cells in vitro. A total of 712 differentially expressed genes were obtained from global transcriptome profiling of A549 cells after PM2.5 exposure. In addition, GO function enrichment analysis revealed that major differentially expressed genes (DEGs) involved in the biological process of the immune system and the response to the stress. KEGG pathway analysis further proposes that infectious disease, cancers, cardiovascular disease, and immune disease pathway were the key human disease events that occur in A549 cells under PM2.5 stress. The data obtained here shed light on the related biological process and gene signaling pathways affected by PM2.5 exposure. This study aids our understanding of the complicated mechanisms related to PM2.5-induced health effects and is informative for the prevention and treatment of PM2.5-induced systemic diseases. PMID- 30276687 TI - Morphophysiological variation and metal concentration in the thallus of Parmotrema tinctorum (Despr. ex Nyl.) Hale between urban and forest areas in the subtropical region of Brazil. AB - Anthropic activities such as the emission of pollutants resulting from industrial and agropastoral activities promote several changes in urban and forest areas. Lichens are organisms that are used in air quality evaluations due to their sensitivity to these changes. The aim of this study is to analyze the presence of morphophysiological damages and the metal concentration in samples of the lichen Parmotrema tinctorum, in urban and forest areas, checking for possible parameter variations between these areas, in the different matrices and seasons in the Southern region of Brazil. Six areas were selected (urban and forest), assigned to the rural/urban and urban/industrial matrices belonging to the watershed of the Rio dos Sinos, Brazil. The following parameters were analyzed: Index of photobiont vitality (IPV), photosynthetic pigments (chlorophyll, carotene, and pheophytin) and metals (Cu, Cr, Zn, Pb, and Ni) in the thallus of the lichen. The data were analyzed by an ANOVA one way, Pearson correlation test, and principal component analysis (PCA). Variations in the morphophysiological parameters were recorded in all the areas revealing significant differences. The lowest IPV values and highest concentration of metals were recorded in the urban environment, while low chlorophyll levels were found in the forest areas. The PCA showed a distinction between the areas and the season. The level of urbanization, vehicle traffic, and the weather conditions might have influenced the results. The use of P. tinctorum, the index of photobiont vitality and chlorophyll and pheophytin content, has proved to be an efficient tool to diagnose the air quality in the areas analyzed, allowing its use as a model in air monitoring studies, both in urban and forest areas, as well as in distinct matrices in the subtropical region. PMID- 30276688 TI - Hybrid UV-C/microfiltration process in membrane photoreactor for wastewater disinfection. AB - A novel hybrid UV-C/microfiltration process for water disinfection is presented, and its application in continuous mode operation to the removal of different pathogen germs (Escherichia coli, Enterococcus faecalis, and Candida albicans) present in urban wastewater. The membrane photoreactor is based on porous stainless steel membranes coated with a TiO2 layer and illuminated by a UV-C lamp (254 nm). A valve actuator in the outlet of the UV-C stream allows operation of the system under conditions of constant transmembrane pressure (TMP) keeping the UV-C contact time in few seconds, significantly lower than the typical irradiation time employed in TiO2 photocatalytic processes. An E. coli removal of up to 4-log in the permeate stream and up to 2-log in the UV-C outlet was achieved with a 0.2 MUm membrane operating with a TMP of 0.5 bar and a UV-C contact time as low as 8 s. The microbial balance data from the cells recovered from the membrane confirmed that 96-98% of the removed microorganisms died due to the UV-C action over the membrane surface. Modification of the membrane with a TiO2 layer has been also shown to be a suitable way to improve both the UV-C inactivation and the filtration efficiency. The results reported in this work constitute a proof of concept of the synergy between UV-C and filtration that can be achieved in a hybrid UV-C/microfiltration system, being a good example of process intensification where two products of different quality can be simultaneously obtained. PMID- 30276690 TI - Carbon dioxide emissions, total factor productivity, ICT, trade, financial development, and energy consumption: testing environmental Kuznets curve hypothesis for Tunisia. AB - The main objective of this study is to examine the linkage between CO2 emissions, total factor productivity as a measure of income, information and communication technology (ICT), trade, financial development, and energy consumption in Tunisia from 1975 to 2014. To achieve this goal, the autoregressive distributed lag (ARDL) with the break point method is performed. The results demonstrate the rejection of the Kuznets environmental curve (EKC) hypothesis by obtaining a higher value of the long-term total factor productivity parameter compared to the short-term one. Moreover, our result shows an insignificant impact of ICT on CO2 emissions as a measure of pollution. In addition, trade, financial development, and energy consumption affect negatively the environmental quality. As a result, Tunisian policymakers should enhance the total factor productivity, expand the information and communication technology, further develop the financial sector, enhance the share of renewable energy consumption, and reduce the energy consumption resulting in import and export goods. These goals will be achieved by improving Tunisia's technological and innovation capacity, enhancing the use of ICT in transport, building, and industry sectors considered as the most pollutant ones, and creating renewable energy projects.

AB - The present study searches the effects of international oil prices on the performance of financial sector firms in the Amman Stock Exchange (ASE). Using the daily data which range from July 3, 2006 to April 12, 2018, we found that financial performance of the ASE firms is downturn during this data period and oil prices do not impact on these performances. It is found that downward movement of financial performances in the ASE is totally independent of the movements in international oil prices. PMID- 30276689 TI - Effect of Fe-functionalized biochar on toxicity of a technosol contaminated by Pb and As: sorption and phytotoxicity tests. AB - Biochar, produced by the pyrolysis of biomass under low oxygen conditions, has gathered attention in the last few years due to its capability to reduce metal(loid)s bioavailability and mobility in soils, as well as its beneficial effects on soil fertility. Indeed, biochar amendment to polluted soil induced usually an increase of pH, water holding capacity, and nutrient contents, associated with a decrease of metal(loid)s concentrations in soil pore water, through sorption. However, biochar has been shown efficient in sorbing cation pollutants, like Pb, but present a low sorption capacity towards anions like As. This contrasted behavior poses a problem, as most polluted soils are multi contaminated, with both cation and anion pollutants. One of the solutions to overcome such problem is to functionalize biochar, by modifying its surface. However, most studies actually focused on functionalization effect on metal(loid)s sorption towards batch experiments, and only a few dealt with modified biochar incorporation to the soil. Therefore, this study aimed (i) to assess the sorption capacity of hardwood biochars, harboring different particle sizes, towards Pb and As; (ii) to evaluate the effect of a Fe-functionalization on Pb and As sorption; and (iii) to validate the results, in a phytotoxicity test using Phaseolus vulgaris as bioindicator plant. The batch experiments showed that all four biochars were able to efficiently sorb Pb, the fine biochars showing higher sorption values than the coarse biochars. As sorption was very low. Fe coating increased As sorption value, while having no effect on Pb sorption. However, when incorporated in the soil, Fe-coated biochar did not improve soil physico-chemical properties compared to the pristine biochar; especially, it did not reduce As soil pore water concentrations. Finally, bean plant did not show differences in terms of biomass production between the two biochars incorporated into polluted soil, demonstrating that Fe-functionalization did not improve biochar capacity to decrease soil toxicity. PMID- 30276692 TI - Evolution of inorganic pollutants from landfills in shallow aquifers of different hydrogeological systems in Lithuania. AB - This study examines the patterns of evolution in inorganic macrocomponent speciation and the saturation state of the landfill leachate-polluted groundwater of three closed unlined landfills that are located in different hydrogeological systems (open, semi-open and closed) but are similar in both their volumes of landfill waste and the hazard levels of their landfill pollutants. Multivariate statistical analysis and geochemical modelling were conducted. The results showed that as the intensity of landfill pollution dispersion in groundwater along the flow path decreased, hydrochemical and hydrodynamic processes occurred with different intensities in open, semi-open and closed hydrogeological systems. In the open hydrogeological system, the processes of sulphate reduction, iron oxidation and chloride dilution and dispersion were up to 10-30% more intensive than those in the semi-open and closed hydrogeological systems. In the semi-open and closed hydrogeological systems, the processes of calcium, magnesium and iron carbonate equilibrium shifting towards carbonate precipitation were up to 15-40% more intensive than those in the open hydrogeological system. The results obtained in this research may be used to predict the dispersion of pollution in the groundwater of landfills located in similar hydrogeological systems and to facilitate the selection of prevention measures to limit pollution dispersion in groundwater. PMID- 30276693 TI - A comparative evaluation of the performance of full-scale high-rate methane biofilter (HMBF) systems and flow-through laboratory columns. AB - Methane biofilter (MBF) technology, a cost effective method to control atmospheric emission of CH4, is usually developed as a passively aerated system to control low-volume point-source emissions such as those from landfills with gas collection systems. Actively aerated high-rate methane biofilter (HMBF) systems are designed to overcome the shortcomings of passively aerated systems by ensuring the entire filter bed is utilized for CH4 oxidation. Flow-through column experiments point to the fact that CH4 oxidation rates of actively aerated systems could be several times higher than that of passively aerated systems. However, reports of the performance of field HMBF systems are not available in literature. Furthermore, there are no studies that demonstrate the possibility of using laboratory data in the design and operation of field systems. The current study was conducted to fill this research gap and involve a comparative study of the performance of laboratory columns to field performance of a HMBF system using solution gas produced at an oil battery site as the CH4 source. The actively aerated column studies confirmed past results with high CH4 oxidation rates; one column received air at two injection points and achieved an oxidation rate of 1417 g/m3/d, which is the highest reported value to date for compost-filled columns. Subsequent studies at a specially designed field HMBF filled with compost showed a higher oxidation rate of 1919 g/m3/d, indicating the possibility of exceeding the high CH4 oxidation rates observed in the laboratory. The achievement of observed field oxidation rates being higher than those in the laboratory is attributed to the capability of maintaining higher temperatures in field HMBFs. Furthermore, results show that field HMBFs could operate at lower than stoichiometric air to CH4 ratios, and lower retention times than that of laboratory columns. Results indicated that laboratory columns may not truly represent field behavior, and said results could only be used in the preliminary design of field HMBFs. PMID- 30276694 TI - Submicron particle number doses in the human respiratory tract: implications for urban traffic and background environments. AB - The deposition of ambient submicron particles in the different parts of the human respiratory tract (HRT) was, for the first time, estimated for males and females from different age classes (children-adults-seniors) of urban population in the city of Thessaloniki, northern Greece, during the cold and the warm period of the year. Outdoor daily and hourly particle number doses in the different regions of the HRT, i.e., the extra-thoracic (ET), tracheobronchial (TB), and the acinar (AC) regions, were calculated by employing the Multiple-Path Particle Dosimetry (MPPD) model. Because of the absence of information being available for the hygroscopic properties of particles, three different particle hygroscopicity scenarios were considered: (i) non-hygroscopic (i.e., raw model estimations), (ii) nearly hydrophobic, and (iii) hygroscopic particles. When hygroscopic properties were considered, we found a remarkable reduction (up to ~ 55%) in the estimated total particle number doses in comparison to the non-hygroscopic particle scenario. Furthermore, we found that the size distribution pattern of the particle doses within the different parts of the HRT was strongly affected by particles' hygroscopic properties with the non-hygroscopic particle scenario significantly overestimating the particle doses in the sub-100-nm range, while underestimating the doses of larger particles. On the contrary, the deposition density appeared to be negligibly affected by the particles' hygroscopic properties, implying the existence of a possible threshold in the number of particles deposited per airway surface area. Similarly, the lobar particle number deposition fraction was unaffected by the hygroscopic properties of particles, as well as the ambient particle size distribution and the individuals' physiological parameters. The total particle number deposition doses estimated here are within the range of the corresponding values reported for other urban environments. It is hoped that our findings could contribute to better understanding of submicron particle exposure and add to the development of more sufficient methods to evaluate the related health impacts. PMID- 30276695 TI - The effects of ash inside a platinum-based catalyst diesel particulate filter on particle emissions, gaseous emissions, and unregulated emissions. AB - Ash deposited in the DPF cannot be burnt, which will affect the service life of DPF. However, previous works focused on the effect of ash on the engine exhaust emissions are limited. Therefore, the influence of ash on the emissions was studied in this work. The particle emissions, the gaseous emissions, and the unregulated emissions (carbonyl compounds and volatile organic compounds) were measured by an AMA4000 gaseous analyzer, ELPI, HPLC, and GC-MS, respectively. Research results indicate that the filtration efficiency decreases by 0.57-4.49% for accumulation mode particle of particulate matter, while it has very little effects on the other type and the particle number in the presence of ash. For regular gaseous pollutions, ash has no influence on CO2 and NOx emission, while CO and THC increase by 68.2% and 91.0%, respectively. For unregulated emissions, overall, carbonyl compounds increase by 41-150% and the BTEX decreases by 8.6 23.6% after ash formed. The change is mainly caused by the increase in the exhaust backpressure that plays a key role. PMID- 30276696 TI - VegeSafe: a community science program generating a national residential garden soil metal(loid) database. AB - VegeSafe is a national community science initiative aimed at characterising soils in Australian residential gardens and community gardens. The program has been operating for over 5 years and has generated soil metal(loid) data from over 8600 residential garden and community garden soil samples, submitted by almost 2000 community scientists. The VegeSafe program represents the largest archive of soil metal(loid) data and associated metadata for residential garden soils in Australia. Samples were collected across Australia, with 61% of samples collected from NSW (n = 5284), Victoria (VIC) 20% (n = 1688) of samples and Queensland (QLD) 7% (n = 592) of samples. Soil metal(loid) data obtained by analysis of bulk soil samples by portable X-ray florescence spectrometry (pXRF) for As, Cu, Cr Mn, Pb and Zn showed spatial patterns of greater soil metal(loid) concentrations around city areas, particularly in NSW and VIC. The Australian Health Investigation Levels for low-density residential land uses (HIL-A) were used in this study as guideline values for soil metal(loid) concentrations. Overall, there was a relatively small number of HIL-A exceedances in the dataset, with most metal(loid)s exceeding their HIL-A concentration in < 5% of incidences. The notable exception to this was for Pb, which had HIL-A (300 mg/kg) exceeded in 27% (n = 1427) of samples in NSW, 17% (n = 280) in VIC and 10% (n = 61) in QLD. Through the power of community engagement and community science, the VegeSafe program presents an unprecedented insight into soil metal(loid) concentrations in Australian residential gardens. PMID- 30276697 TI - Phosphorus removal from wastewater using eggshell ash. AB - Eggshell ash was used as an adsorbent to remove phosphorus from wastewater. Adsorbent dose, initial phosphorus concentration, and contact time were investigated to determine the optimum conditions. Results indicate that 5 g of eggshell ash adsorbent with 1.5 mg L-1 of initial phosphorus concentration removed over 90% of the phosphorus. When the temperature was increased, phosphorus removal potential also increased. Specific surface area, morphological features, and structure of the adsorbent were characterized by Brunauer-Emmett Teller (BET) surface area analysis, scanning electron microscopy with energy dispersive X-ray spectrometer (SEM-EDS), and X-ray diffraction (XRD). Results showed prominent calcium, magnesium, and phosphorus in the eggshell ash surface after adsorption. The elemental composition of eggshell ash surfaces before adsorption did not contain phosphorus, revealing that calcium carbonate-based eggshell ash was co-precipitated with calcium phosphate. The adsorption mechanism was studied by applying Langmuir and Freundlich isotherm models. Experimental data fit well with the Langmuir model, which indicates monolayer adsorption. Eggshell ash was also applied as an adsorbent in wastewater at Srinakharinwirot University dormitories, resulting in 80% phosphorus removal within 2 h. These findings indicated that eggshell ash could be applied as an adsorbent for phosphorus treatment and removal from domestic and industrial wastewater. PMID- 30276698 TI - Priming with ACC-utilizing bacterium attenuated copper toxicity, improved oxidative stress tolerance, and increased phytoextraction capacity in wheat. AB - The major challenges for the plants growing in metal-contaminated soils are deficiency of nutrients, biomass reduction, and severe oxidative damages in the presence of heavy metals. In this regard, our aim was to overcome these challenges through the use of efficient microbial strains in metal-polluted soils and to assess its/their physiological and biochemical effects. In the current study, a copper (Cu)-resistant bacterium was isolated from the rhizospheric soil of 'Ziziphus nummularia' and evaluated for its ability to promote the wheat growth under the gradient stress of copper. Based on 16S rRNA gene sequencing, the isolate was identified as Pantoea sp. Among the plant growth promoting tests, the isolate showed the production of indole acetic acid, solubilization of inorganic phosphate, and ACC deaminase activity. Also, the isolate showed resistance to many heavy metals and antibiotics and increased the water-soluble copper in solution. The results of pot studies showed that bacterial application promoted various growth parameters of wheat plants and also enhanced the Cu uptake of wheat from the Cu-amended soil. The results showed that enhancement of Cu stress (100 to 300 mg kg-1) resulted in a decrease in various compatible solutes such as proline, total soluble sugars, and total protein content, and increase in the level of malondialdehyde (MDA), latter of which is the indicator of oxidative stress. Bacterial treatment markedly increased the proline, soluble sugar, total protein content, and decreased the MDA content under Cu stress. In addition, bacterial inoculation significantly alleviated the harmful effect of metal toxicity by decreasing the activation of ROS molecules including superoxide (O2-) and hydrogen peroxide (H2O2). The activation of various antioxidative enzymes such as superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) was noted following bacterial inoculation under Cu stress. Therefore, the present study demonstrates the potential of the isolate Pantoea sp. ZNP-5 to improve the growth and phytoextraction of metal from the metal-polluted soil through the polyphasic mechanism of action.

AB - The Indian river shad, Gudusia chapra (Hamilton, 1822), is a commercially important freshwater clupeid that contribute to the livelihood of subsistence and marginal fisheries in inland open waters of India and its adjacent countries. The present study was carried out on the growth and mortality of Indian River shad, Gudusia chapra (Hamilton, 1822) based on the commercial length-frequency data collected monthly during October 2014 to September 2015 of a large reservoir located in the border of Jharkhand and West Bengal. The ELEFAN-I (Electronic Length Frequency Analysis) module in FiSAT (FAO-ICLARM Stock Assessment Tools) was used for estimation of growth parameters (Linfinity, K). The total mortality was estimated following Pauly (ICLARM Fishbyte 2(1):9-13, Pauly 1983) whereas exploitation ratio and maximum sustainable yield were calculated following Gulland (1979). The asymptotic length (Linfinity) and growth coefficient (K) were estimated as 194 mm and 1.23 year-1, respectively. The species grows to 141.56 and 182.91 mm at the end of the 1st and 2nd years of life. The total natural and fishing mortalities were 6.63, 2.45 and 4.18 year-1 respectively. The value of growth performance index was 2.69. The exploitation ratio (E) was estimated as 0.63. As the exploitation ratio (E) is slightly beyond the optimum, there is likelihood of some threat of overexploitation. Though recruitment was continuous, major pulse was observed during April-May. The present investigation is a first report from Indian reservoir. The maximum sustainable yield of this species was estimated as 485.6 t against the present annual yield of 612.3 t. Avoiding overfishing and wise use of available resources are of prime importance for sustainable fishery management of the reservoir. PMID- 30276700 TI - Dynamics of phosphorus content and the activity of phosphatase in forest soil in the sustained nitrogen compounds emissions zone. AB - This paper summarizes research work on the seasonal and profile dynamics of phosphorus content and the activity of phosphatase in soil next to the nitrogen industry. The results are presented of the total phosphorus (TP) and available phosphorus (AP) content and the alkaline phosphatase (AlP) and acid phosphatase (AcP) against the basic physicochemical properties (clay, pH, total organic carbon, total nitrogen). Three soil profiles were sampled from Brunic Arenosols 0.8, 2.0, and 2.5 km away from the nitrogen plant. The control profile was taken from the Tuchola Forest. The soil was collected in both spring and autumn. The results showed that the total phosphorus content was higher in spring than in autumn (the value of index of changes in time TI < 0) contrary to available phosphorus (TI > 0) and in both seasons in surface soils, the lowest, in profile I. Both total and available phosphorus decreased with depth along the soil profiles. The distribution index (DI) calculated for total phosphorus in surface soils demonstrated a rather moderate accumulation, while DI value for available phosphorus for profile III, a considerable accumulation. The availability factor (AF) for all the soil samples was above the threshold of phosphorus load (2%) in the two seasons in this study (from 2.00 to 10.13% for spring and from 3.92 to 21.19% for autumn), suggesting that the transformation rate from TP to AP was high, and AP supply for plant growth was sufficient. The correlation analysis showed a significant and positive correlation of available phosphorus with soil properties such as total organic carbon (r = 0.577), total nitrogen (r = 0.512), and clay (r = 0.493); however, there was no correlation with the activity of phosphatases.

AB - Black carbon (BC) aerosols were observed over Xi'an (XA) and Hong Kong (HK) to better compare its properties and sources in two geographically separate regions in China. High-BC (7.9 +/- 3.3 MUg.m-3) and -PM2.5 (182 +/- 80.5 MUg.m-3) concentrations were observed in XA, and these were much higher than those in HK (BC, 3.2 +/- 0.9 MUg.m-3; PM2.5, 34.5 +/- 9.3 MUg.m-3). The contribution of BC to PM2.5 in HK reached 10.7%, which was ~ 1.5 times than that in XA (7.6%). The results emphasized that BC played an important role in HK PM2.5. The diurnal distribution of HK BC was highly correlated with vehicle emissions during the daytime; it peaked during heavy traffic times. Whereas XA BC exhibited flat distribution owing to stable BC sources. It is not markedly driven by traffic patterns. Additionally, the potential source contribution function (PSCF) analysis showed that XA BC mainly originated from local emissions while nearly half of the HK BC originated from distant sources, such as industrial emissions from northeastern regions and ship emissions from marine regions. These anthropogenic BC sources were found to be regional in nature based on multilinear engine (ME-2) analysis. Specifically, the XA BC sources were dominated by three factors: 22.5% from coal burning, 19.6% from biomass burning, and 32.9% from vehicle emissions. In HK, the majority of BC contributions originated from vehicle and ship emissions (78.9%), while only 14.5% and 1.5% originated from coal and biomass burning from residential combustion, as well as industrial and power plants in inland China. PMID- 30276702 TI - Sulfate supply enhances cadmium tolerance in Vicia faba L. plants. AB - Sulfur deficiency and cadmium (Cd) pollution are two ubiquitous constraints affecting plant growth in agricultural soils. However, facing the situation of sulfur deficiency, whether surplus sulfate supply can affect Cd toxicity in plants is still unclear. Therefore, in the present study, experiments with deficient, sufficient, and excess sulfate levels under Cd stress were conducted in faba bean plants hydroponically. We found that sulfate supply significantly increased biomass of Cd-stressed plants when compared with deficient sulfate treatment. Intriguingly, sulfate application also increased Cd concentrations in leaves. Based on increased Cd concentrations without retarding plant growth, we conclude that sulfate supply enhances Cd tolerance in faba bean plants. Sulfate application increased CdSO40 proportion in the growth medium which is partially related to the increase of Cd in plants because the diffusion of CdSO40 is faster than Cd2+ in plants. Further study on Cd localization showed that this heavy metal was prone to accumulate in the epidermis of leaves as affected by sulfate which might contribute to enhancement of Cd tolerance. Oxidative stress induced by Cd toxicity was alleviated by surplus sulfate supply compared with deficient sulfate. Although capacities of total antioxidants were increased by sulfate in Cd-stressed plants, phenolic compounds as one kind of important antioxidants were unchanged, suggesting that sulfate has no effect on phenolic compounds for scavenging ROS under Cd stress. Taken together, sulfate accelerates Cd accumulation in the epidermis of leaves in faba bean giving rise to higher Cd tolerance.

AB - Social support enhances self-management and prevention of behaviors and is typically assessed using self-report scales; however, little is known about the validity of these scales in HIV-infected or affected populations. This systematic review aims to identify available validated social support scales used in HIV infected and HIV-affected populations. A systematic literature search using key search terms was conducted in electronic databases. After rounds abstract screenings, full-text reviews, and data abstraction 17 studies remained, two of which assessed multiple social support scales, which increased number of scales to 19. Most scales assessed positive social support behaviors (n = 18). Most scales assessed perceived social support (n = 14) compared to received social support. Reliability ranged from 0.67 to 0.97. The most common forms of validation reported were content validity and construct validity and the least was criterion-related validity. Future research should seek to build evidence for validation for existing scales used in HIV-infected or HIV-affected populations.

AB - PURPOSE: The optimal method for detecting CMV colitis in patients with inflammatory bowel disease (IBD) has not been established. We wanted to investigate which diagnostic test would be most accurate when defining CMV colitis rather by the further clinical course than by using another diagnostic modality. METHODS: All consecutive patients with moderately or severely active IBD who had been tested for CMV by PCR, histology, or antigenemia assay at the two campuses CBF and CCM of the Charite - Universitatsmedizin Berlin between September 2006 and September 2009 were included in this retrospective study. During that time, in patients with a positive CMV test, immunosuppressive treatment of any kind was immediately reduced and antiviral treatment was started. This allowed identifying patients who responded to antiviral treatment and those who only responded to later escalation of immunosuppressive therapy. RESULTS: One hundred and nine patients were identified, out of whom nine were considered to have clinically relevant CMV colitis. Sensitivity and specificity were 1 and 0.94 for CMV PCR and 0.5 and 1 for pp65 antigen immunofluorescence assay from peripheral blood, 0.67 and 0.98 for immunohistochemistry, and 0.17 and 0.98 for hematoxylin-eosin staining. When using absence of leukocytosis, splenomegaly, and steroid refractory disease as clinical parameters to test for CMV colitis, blood CMV PCR and immunohistochemistry were able to exclude CMV colitis in negative patients with a 75% likelihood of positive patients to have clinically relevant CMV colitis. CONCLUSIONS: Blood-based CMV PCR together with simple clinical parameters can exclude clinically relevant CMV colitis at a high specificity.

AB - Chitinolytic enzymes are capable to catalyze the chitin hydrolysis. Due to their biomedical and biotechnological applications, nowadays chitinolytic enzymes have attracted worldwide attention. Chitinolytic enzymes have provided numerous useful materials in many different industries, such as food, pharmaceutical, cosmetic, or biomedical industry. Marine enzymes are commonly employed in industry because they display better operational properties than animal, plant, or bacterial homologs. In this mini-review, we want to describe marine chitinolytic enzymes as versatile enzymes in different biotechnological fields. In this regard, interesting comments about their biological role, reaction mechanism, production, functional characterization, immobilization, and biotechnological application are shown in this work. PMID- 30276710 TI - The role of drug-induced sleep endoscopy: predicting and guiding upper airway surgery for adult OSA patients. AB - PURPOSE: Obstructive sleep apnea (OSA) is a common sleep disorder that can be corrected with upper airway surgery. Prior to surgery, drug-induced sleep endoscopy (DISE) is routinely used to evaluate obstruction sites and severity. Evidence suggests that the findings of DISE may relate to the final surgical outcome. Therefore, we evaluated the ability of drug-induced sleep endoscopy to predict the final effect of upper airway surgery and potentially to guide surgical treatment decision-making. METHODS: A retrospective analysis was conducted on 85 adult patients with OSA (50 men with mean apnea-hypopnea index [AHI] 30 +/- 15 events/h) who underwent DISE followed by tonsillectomy, uvulopalatopharyngoplasty (UPPP), or a combination of the two. Surgery outcome was evaluated at follow-up by polysomnography. Success response to surgery was defined as a postoperative value of the AHI< 20 events/h and more than 50% postoperative reduction of AHI. RESULTS: Of the 85 patients evaluated, 48 (53%) were responders. DISE revealed significant differences between the two groups. Specifically, complete circumferential collapse at the velum and complete anterior-posterior collapse at the tongue base occurred at higher frequencies in nonresponders. In contrast, the presence of grade 3-4 tonsillar hypertrophy and anterior-posterior mild/partial collapse at the velum were positively associated with responders. CONCLUSIONS: Our results suggest that DISE may help predict the final outcome of tonsillectomy, UPPP, or a combination of the two in adult patients with OSA. The use of DISE shows potential to guide treatment decisions for individual patients with OSA. PMID- 30276713 TI - The accD3 gene for mycolic acid biosynthesis as a target for improving fatty acid production by fatty acid-producing Corynebacterium glutamicum strains. AB - We have recently developed Corynebacterium glutamicum strains that produce free fatty acids in culture supernatant due to enhanced fatty acid biosynthesis. Of these producing strains, the basic producer PAS-15 has a defect in the gene for a fatty acid biosynthesis repressor protein, and the advanced producer PCC-6 has two additional mutations to augment the production by strain PAS-15. The aim of the present study was to obtain novel genetic traits for improving fatty acid production by these producers. A new mutant with increased production derived from strain PAS-15 had a missense mutation in the accD3 gene (mutation accD3A433T), which is involved in the biosynthesis of mycolic acids that are cell envelope lipids of C. glutamicum, as the causal mutation. Mutation accD3A433T was verified to reduce the AccD3 enzymatic activity and increase fatty acid production in strain PAS-15 by 1.8-fold. Deletion of the accD3 gene in strain PAS 15, which was motivated by the characteristic of mutation accD3A433T, increased fatty acid production by 3.2-fold. Susceptibility of strain PAS-15 to vancomycin was significantly increased by accD3 gene deletion and by mutation accD3A433T to the intermediate level, suggesting that the cell envelope permeability barrier by mycolic acids is weakened by this engineering. Furthermore, mutation accD3A433T also increased fatty acid production in strain PCC-6 by 1.3-fold. These increased production levels were suggested to be involved not only in the redirection of carbon flux from mycolic acid biosynthesis to fatty acid production but also in the permeability of the cell envelope. PMID- 30276712 TI - Global and pathway-specific transcriptional regulations of pactamycin biosynthesis in Streptomyces pactum. AB - Pactamycin, a structurally unique aminocyclitol natural product isolated from Streptomyces pactum, has potent antibacterial, antitumor, and anti-protozoa activities. However, its production yields under currently used culture conditions are generally low. To understand how pactamycin biosynthesis is regulated and explore the possibility of improving pactamycin production in S. pactum, we investigated the transcription regulations of pactamycin biosynthesis. In vivo inactivation of two putative pathway-specific regulatory genes, ptmE and ptmF, resulted in mutant strains that are not able to produce pactamycin. Genetic complementation using a cassette containing ptmE and ptmF integrated into the S. pactum chromosome rescued the production of pactamycin. Transcriptional analysis of the DeltaptmE and DeltaptmF strains suggests that both genes control the expression of the whole pactamycin biosynthetic gene cluster. However, attempts to overexpress these regulatory genes by introducing a second copy of the genes in S. pactum did not improve the production yield of pactamycin. We discovered that pactamycin biosynthesis is sensitive to phosphate regulation. Concentration of inorganic phosphate higher than 2 mM abolished both the transcription of the biosynthetic genes and the production of the antibiotic. Draft genome sequencing of S. pactum and bioinformatics studies revealed the existence of global regulatory genes, e.g., genes that encode a two-component PhoR-PhoP system, which are commonly involved in secondary metabolism. Inactivation of phoP did not show any significant effect to pactamycin production. However, in the phoP::aac(3)IV mutant, pactamycin biosynthesis is not affected by external inorganic phosphate concentration. PMID- 30276714 TI - Transcriptome analysis of the response of silkworm to drastic changes in ambient temperature. AB - Bombyx mori is a poikilothermic insect and is economically important for silk production. Drastic changes in the ambient temperature have a negative impact on sericulture. However, the reason as to why high temperature is associated with the occurrence of diseases in silkworm and the response of silkworm to low temperature remain unclear and were the focus of the present study. Dazao silkworm exposed to 13 degrees C (DZ-13), 25 degrees C (DZ-25), and 37 degrees C (DZ-37) were used for RNA-seq analysis. There were 478 and 194 upregulated differentially expressed genes (DEGs) in DZ-13 and DZ-37 while 49 and 273 downregulated DEGs in DZ-13 and DZ-37, respectively. Eight DEGs were co upregulated, in which seven genes were for heat shock proteins (Hsps), implying that Hsps play important roles in the tolerance of silkworm to high and low temperature. Gene ontology analysis revealed that the developmental process was downregulated in DZ-13. All the DEGs in the oxidative phosphorylation and insulin signaling pathways were upregulated in DZ-13. Several cuticular proteins and ATP synthesis-related genes were upregulated in DZ-13, suggesting that thickening of the cuticle and increase in the ATPase expression would help silkworms to protect themselves from low temperature-induced stress. Several immune-related genes, such as BmRel and BmSerpin-2, were downregulated in DZ-37, revealing that the resistance of silkworm is decreased under high temperature shock resulting in susceptibility to pathogens. Thus, the increase in the thermo-tolerance of silkworm should be related to the enhancement in the pathogen resistance. PMID- 30276715 TI - The time response of anaerobic digestion microbiome during an organic loading rate shock. AB - Knowledge of connections between operational conditions, process stability, and microbial community dynamics is essential to enhance anaerobic digestion (AD) process efficiency and management. In this study, the detailed temporal effects of a sudden glycerol-based organic overloading on the AD microbial community and process imbalance were investigated in two replicate anaerobic digesters by a time-intensive sampling scheme. The microbial community time response to the overloading event was shorter than the shifts of reactor performance parameters. An increase in bacterial community dynamics and in the abundances of several microbial taxa, mainly within the Firmicutes, Tenericutes, and Chloroflexi phyla and Methanoculleus genera, could be detected prior to any shift on the reactor operational parameters. Reactor acidification already started within the first 24 h of the shock and headed the AD process to total inhibition in 72 h alongside with the largest shifts on microbiome, mostly the increase of Anaerosinus sp. and hydrogenotrophic methanogenic Archaea. In sum, this work proved that AD microbial community reacts very quickly to an organic overloading and some shifts occur prior to alterations on the performance parameters. The latter is very interesting as it can be used to improve AD process management protocols. PMID- 30276716 TI - Proteomic characterization and antifungal activity of potato tuber proteins isolated from starch production waste under different temperature regimes. AB - Proteins were obtained from effluent of a starch manufacture by using different isolation temperatures (40, 60, 80, and 100 degrees C). The proteins, remaining in effluent after treatment of potato juice at 80 and 100 degrees C differed significantly in composition and in structural stability as well as in trypsin inhibitory and antifungal activities in comparison with the variants of 40 and 60 degrees C. The protein samples of 80 degrees C exhibited the highest antifungal activity and its average value of IC50 against five strains of two Fusarium species was determined in average at 0.18 mg ml-1. The 80 degrees C protein samples consisted predominantly of low-molecular proteins (7-17 kDa) identified as potato tuber protease inhibitors I and II. Predominantly, protease inhibitors II were identified for the protein samples obtained by 100 degrees C and here we identified 7 spots in comparison with 12 identified for the 80 degrees C samples. Samples of 40 and 60 degrees C with low antifungal activities represent high variability of detected and identified proteins. We identified various representatives of aspartic, cysteine, and serine protease inhibitors in both types of samples. These samples also contained Kunitz-type protease inhibitors that were not found in the 80 and 100 degrees C samples which documented thermal unstableness of Kunitz-type protease inhibitors. Functional stability at high temperatures and antifungal activity of isolated potato protease inhibitors I and II support the potential of this fraction usage in food, feed, pharmaceutical, or agricultural industry and offer new products for starch manufactures. At the same time, utilization of the stable protein fraction of waste deproteinized potato water promotes exploitation of potato starch production resources. PMID- 30276717 TI - Mild Exercise Differently Affects Proteostasis and Oxidative Stress on Motor Areas During Neurodegeneration: A Comparative Study of Three Treadmill Running Protocols. AB - Proteostasis and oxidative stress were evaluated in motor cortex and spinal cord of aged Lewis rats exposed to 1 mg/kg/day of rotenone during 4 or 8 weeks, prior or after practicing three protocols of mild treadmill running. Results demonstrated that exercise done after the beginning of neurodegeneration reverted the increased oxidative stress (measured by H2O2 levels and SOD activity), increased neuron strength, and improved proteostasis in motor cortex. Spinal cord was not affected. Treadmill running practiced before neurodegeneration protected cortical motor neurons of the rotenone-exposed rats; but in this case, oxidative stress was not altered, whereas proteasome activity was increased and autophagy decreased. Spinal cord was not protected when exercise was practiced before neurodegeneration. Prolonged treadmill running (10 weeks) increased oxidative stress, autophagy, and proteasome activity, whereas neuron viability was decreased in motor cortex. In spinal cord, this protocol decreased oxidative stress and increased proteasome activity. Major conclusions were that treadmill running practiced before or after the beginning of neurodegeneration may protect motor cortex neurons, whereas prolonged mild running seems to be beneficial for spinal cord. PMID- 30276718 TI - Hydroxyurea Exposure and Development of the Cerebellar External Granular Layer: Effects on Granule Cell Precursors, Bergmann Glial and Microglial Cells. AB - The current paper presents a histological analysis of the cell death in the cerebellar external granular layer (EGL) following the treatment with a single dose (2 mg/g) of hydroxyurea (HU). The rats were examined at postnatal days (P) 5, 10, and 15, and sacrificed at appropriate times ranging from 6 to 48 h after treatment administration. Studies were done in each cortical lobe (anterior, central, posterior, and inferior). The quantification of several parameters, such as density of 5-bromo-2'-deoxyuridine, TUNEL, vimentin, and tomato lectin-stained cells, revealed that HU compromises the viability of EGL cells. Our results indicate that P10 is a time of high vulnerability to injury. We also show here that the anterior and central lobes are the cortical regions most susceptible to the action of the HU. Additionally, our data also indicate that from 6 to 24 h after HU-exposure is a time-window of high sensibility to this agent. On the other hand, our ultrastructural analysis confirmed that HU administration produces the activation of apoptotic cellular events in the EGL, resulting in a substantial number of dying cells. Different stages of apoptosis can be observed in all cortical lobes at all investigated postnatal ages and survival times. Moreover, we observed that dying neuroblasts were covered by laminar processes of Bergmann glia, and that these unipolar astrocytes presented cytological features of phagocytes engulfing apoptotic bodies and cell debris. The electron microscopy study also revealed the participation of ameboid microglial cells in the phagocytosis of apoptotic cells in the regions of the EGL with extensive cell death. PMID- 30276719 TI - The Effect of Vancomycin on the Viability and Osteogenic Potential of Bone Derived Mesenchymal Stem Cells. AB - Traditionally, methicillin-resistant Staphylococcus aureus (MRSA) is treated with vancomycin, administrated intravenously or applied directly onto infected tissue. The effect of direct (as opposed to systemic) vancomycin treatment on bone formation and remodelling is largely unknown. The minimal inhibitory concentration (MIC) of vancomycin was determined by adding 200 MUL of different concentrations (1-20 MUg/mL) to actively growing cultures of S. aureus Xen 31 (methicillin-resistant) and S. aureus Xen 36 (methicillin-sensitive), respectively, and recording changes in optical density over 24 h. Bone marrow derived and proximal femur-derived mesenchymal stem cells (bmMSCs and pfMSCs) from rat femora were exposed to 1 * MIC (5 MUg/mL) and 4 * MIC (20 MUg/mL) of vancomycin for 7 days. Cell viability was determined by staining with crystal violet and MTT (3-(4,5- di methylthiazol-2-yl)-2,5-diphenyltetrazolium bromide), respectively, and osteogenic differentiation by staining with Alizarin Red S. Vancomycin had no effect on the viability of bmMSCs and pfMSCs, even at high levels (20 MUg/mL). The osteogenic differentiation of pfMSCs was partially inhibited, while osteogenesis in bmMSCs was not severely affected. The direct application of vancomycin to infected bone tissue, even at excessive levels, may preserve the viability of resident MSC populations. PMID- 30276720 TI - Survival and Goat Milk Acidifying Activity of Lactobacillus rhamnosus GG Encapsulated with Agave Fructans in a Buttermilk Protein Matrix. AB - Lactobacillus rhamnosus GG (L. rhamnosus GG) cells were encapsulated in buttermilk proteins by spray drying, alone (E), or with Agave tequilana fructans (CEF). Buttermilk proteins acted as a thermo-protector for the probiotic cells undergoing the spray-dried process. The addition of Agave fructans in CEF microcapsules significantly enhanced storage stability and survival to in vitro simulated gastrointestinal conditions, compared to E capsules. After 14 days storage at - 20 degrees C, the number of living cells in CEF microcapsules was in the order of 7.7 log CFU * mL-1 and the survivability in simulated gastrointestinal environment was 73.23%. Spray-dried microparticles were cultured in goat milk to study biomass production. Agave fructans offered a favorable microenvironment and better growth substrate. The population of CEF viable cells reached 1.08 +/- 0.02 * 1010 CFU * mL-1 after 18 h of fermentation. In contrast, the population of E viable cells were 3.0 +/- 0.01 * 109 CFU * mL-1. The generation time of CEF, L. rhamnosus GG was 15% faster than E, L. rhamnosus GG. Encapsulation with buttermilk proteins in the presence of Agave fructans by spray drying could be suitable for preservation of probiotic powders and may be for a more effective application of probiotics in goat dairy products. PMID- 30276721 TI - FGF8 induces therapy resistance in neoadjuvantly radiated rectal cancer. AB - PURPOSE: Therapy response to neoadjuvant radiochemotherapy (nRCT) of locally advanced rectal cancer varies widely so that markers predicting response are urgently needed. Fibroblast growth factor (FGF) and FGF receptor (FGFR) signaling is involved in pro-survival signaling and thereby may result in radiation resistance. METHODS: In a cohort of 43 rectal cancer patients, who received nRCT, we analyzed protein levels of FGF 8 and its downstream target Survivin by immunohistochemistry to assess their impact on nRCT response. In vitro resistance models were created by exposing colorectal cancer cell lines to fractionated irradiation and selecting long-term survivors. RESULTS: Our findings revealed significantly higher FGF8 and Survivin staining scores in pre-treatment biopsies as well as in surgical specimens of non-responsive compared to responsive patients. Functional studies demonstrated dose-dependent induction of FGF8 mRNA expression in mismatch-incompetent DLD1 cells already after one dose of irradiation. Surviving clones after one or two series of radiation were more resistant to an additional radiation fraction than non-irradiated controls and showed a significant increase in expression of the FGF8 receptor FGFR3 and of Survivin on both the RNA and the protein levels. CONCLUSION: The results of this study suggest that FGF8 and Survivin contribute to radiation resistance in rectal cancer and may serve as markers to select patients who may not benefit from neoadjuvant radiotherapy. PMID- 30276722 TI - Fixation of flail chest or multiple rib fractures: current evidence and how to proceed. A systematic review and meta-analysis. AB - PURPOSE: The aim of this systematic review and meta-analysis was to present current evidence on rib fixation and to compare effect estimates obtained from randomized controlled trials (RCTs) and observational studies. METHODS: MEDLINE, Embase, CENTRAL, and CINAHL were searched on June 16th 2017 for both RCTs and observational studies comparing rib fixation versus nonoperative treatment. The MINORS criteria were used to assess study quality. Where possible, data were pooled using random effects meta-analysis. The primary outcome measure was mortality. Secondary outcome measures were hospital length of stay (HLOS), intensive care unit length of stay (ILOS), duration of mechanical ventilation (DMV), pneumonia, and tracheostomy. RESULTS: Thirty-three studies were included resulting in 5874 patients with flail chest or multiple rib fractures: 1255 received rib fixation and 4619 nonoperative treatment. Rib fixation for flail chest reduced mortality compared to nonoperative treatment with a risk ratio of 0.41 (95% CI 0.27, 0.61, p < 0.001, I2 = 0%). Furthermore, rib fixation resulted in a shorter ILOS, DMV, lower pneumonia rate, and need for tracheostomy. Results from recent studies showed lower mortality and shorter DMV after rib fixation, but there were no significant differences for the other outcome measures. There was insufficient data to perform meta-analyses on rib fixation for multiple rib fractures. Pooled results from RCTs and observational studies were similar for all outcome measures, although results from RCTs showed a larger treatment effect for HLOS, ILOS, and DMV compared to observational studies. CONCLUSIONS: Rib fixation for flail chest improves short-term outcome, although the indication and patient subgroup who would benefit most remain unclear. There is insufficient data regarding treatment for multiple rib fractures. Observational studies show similar results compared with RCTs. PMID- 30276723 TI - Displaced distal radius fractures in children, cast alone vs additional K-wire fixation: a meta-analysis. AB - PURPOSE: Displaced distal radius fractures in children are common and often treated by reduction and cast immobilization. Redisplacement occurs frequently and may be prevented by additional treatment with K-wire fixation after initial reduction. This meta-analysis aims to summarize available literature on this topic and determine if primary K-wire fixation is the preferred treatment for displaced distal radius fractures in children. METHODS: A search in eight databases identified studies that compared cast immobilization alone to additional K-wire fixation as treatment for displaced paediatric distal radius fractures. The primary outcome was the redisplacement rate. Secondary outcomes were secondary reduction rate, range of motion and complications. This meta analysis was performed according to the preferred reporting items for systematic reviews and meta-analysis (PRISMA) statement. RESULTS: Three RCTs and 3 cohort studies, analysing 197 patients treated with cast immobilization alone and 185 with additional K-wire fixation, were included in this meta-analysis. Redisplacement occurred less frequently after additional K-wire fixation than after cast alone (3.8 versus 45.7%; OR 0.07, 95% CI 0.03-0.15). Secondary reduction was performed in 59.8% of the redisplaced fractures. Complications, other than redisplacement, occurred more often after additional K-wire fixation than after cast alone (15.7 versus 3.6%). Range of motion did not differ after both treatments. CONCLUSIONS: Additional K-wire fixation is a suitable treatment to prevent redisplacement and secondary operations after initial reduction of displaced distal radius fractures in children, but is associated with post procedural complications. Additional K-wire fixation does not result in a better range of motion than cast immobilization alone. More research is needed to identify those patients who will benefit the most from K-wire fixation as a treatment for displaced distal radius fractures in children. PMID- 30276724 TI - Epidemiology and treatment of distal radius fractures: current concept based on fracture severity and not on age. AB - PURPOSE: A shift towards surgical treatment of distal radius fractures seems to be apparent. The purpose of the present study was to assess current epidemiological data, the fracture severity according to the AO classification and the changing trend in the treatment. METHODS: This study presents a retrospective review of 268 patients >= 18 years of age admitted to our level I trauma center with distal radius fractures between 2013 and 2015. The data were obtained from the hospital inpatient enquiry system and review of the radiological examinations. RESULTS: The ratio between males and females was 87:181. The average age of the patients was 56.9 (18-99) years. A fall from standing position was the most common mechanism of injury. According to the AO classification, 43.3% were type A fractures, 13.1% type B, and 43.7% type C. As the intensity of the injury mechanism increased, the percentage of type C fractures also increased. A total of 61.9% of patients underwent surgery with open reduction and internal fixation with volar locking plates used as the preferred surgical treatment. Fracture severity correlated well with surgical decision. Elderly patients were just as likely to get surgical treatment as adult patients. CONCLUSIONS: Our findings confirmed the increasing popularity of surgical intervention with open reduction and internal fixation. Contrary to previous studies, the fracture type profile showed an equal proportion of type A and C fractures and the indication for surgical treatment correlated with fracture severity and not age. PMID- 30276725 TI - Circulation of Influenza Virus in the 2015/2016 Epidemic Season in Poland: Serological Evaluation of Anti-hemagglutinin Antibodies. AB - The diagnostic of influenza virus infections is possible using molecular biology methods as well as the analysis of anti-hemagglutinin (anti-HA) antibodies in the blood serum. The aim of this study was to determine the level of anti-HA antibodies in 7 age groups of patients during the 2015/2016 epidemic season in Poland. A total of 1050 serum samples were tested using the hemagglutination inhibition (HAI) assay. We confirmed the presence of anti-HA antibodies for the influenza virus strains: A/California/7/2009(H1N1)pdm09, A/Switzerland/9715293/2013(H3N2), and B/Phuket/3073/2013, which were the components of the influenza vaccine for the 2015/2016 epidemic season. The level of specific anti-HA antibodies was different in each age group. The geometric mean titers were highest at age 5-9 years, where the antibody protection level reached 61.3% against B/Phuket/3073/2013 and 52.7% for A/Switzerland/9715293/2013(H3N2) antigen. The antibody level amounted to 56.7% against for antigen B at age 45-64. In the remaining age groups, the protection levels for all hemagglutinin types did not exceed 50%. These findings confirm the urgent need to increase a persistently low influenza vaccination coverage in the Polish population, which may have had its part in the noticeable increase in the confirmed cases of influenza and influenza-like virus infection during the season. PMID- 30276726 TI - Influence of Socio-Economic Status on Lung Function in Male Adolescents in Tanzania. AB - A lower socio-economic status (SES) associates with increased morbidity and mortality. The goal of this study was to define the influence of SES on lung function in indigenous male adolescents (aged 12.8-24.5 years) in Tanzania. The subjects were subdivided into two age groups: <17.5 (n = 189) and >= 17.5 years of age (n = 101). They underwent anthropometric and spirometry evaluation. The SES was assessed on the basis of economic family resources and the subjects' nutritional status, and was stratified into three categories: SES-1 (low), SES-2 (average), and SES-3 (high). Relative contributions of body mass index, chest expansion/mobility, waist-to-chest ratio, and SES to spirometry variables were statistically determined. We found significant differences in forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) in the older, but not younger age group, by the SES category. The adolescents aged >=17.5 in high-SES-3 category had FEV1 and FVC greater by 29.3% and 42.5%, respectively, than those in low-SES-1 category in the same age group. There also were differences between the two age groups. The mean FEV1 and FVC in adolescents of high-SES-3 category, aged >=17.5, were higher by 65.3% and 82.2%, respectively, than those in the corresponding SES-3 in adolescents aged <17.5. In younger adolescents, lung function variables associated mostly with body build parameters, whereas in older adolescents with SES. The study revealed a significant dependence of lung function, and thus plausibly a greater resistance to diseases, on the socio economic status. We conclude that the socio-economic status be taken into consideration in the assessment of lung function in epidemiological and public health programs, particularly in the context of the developing countries, to obtain the most reliable results. PMID- 30276727 TI - Rituximab in routine care of severe active rheumatoid arthritis : A prospective, non-interventional study in Germany. AB - OBJECTIVE: To assess safety, effectiveness and onset of effect of rituximab (RTX) in routine clinical treatment of severe, active rheumatoid arthritis (RA). METHODS: Prospective, multi-centre, non-interventional study in rheumatological outpatient clinics or private practices in Germany. RTX-naive adult patients were to receive RTX according to marketing authorisation and at their physician's discretion. Also according to their physician's discretion, patients could receive a second cycle of RTX (re-treatment = treatment continuation). Major outcome was the change in Disease Activity Score based on 28-joints count and erythrocyte sedimentation rate (DAS28-ESR) over 24 weeks and during 6 months of re-treatment. RESULTS: Overall, 1653 patients received at least one cycle RTX; 99.2% of these had received disease-modifying antirheumatic drugs (DMARD) pre treatment and 75.5% anti-tumor necrosis factor(TNF)-alpha pre-treatment. After a mean interval of 8.0 months, 820 patients received RTX re-treatment. Mean DAS28 ESR decreased from 5.3 at baseline to 3.8 after 24 weeks (-1.5 [95% confidence interval, CI: -1.6; -1.4]), and from 4.1 at start of cycle 2 to 3.5 at study end (change from baseline: -1.8 [95% CI: -2.0; -1.7]). Improvements in DAS28-ESR and Health Assessment Questionnaire (HAQ) score occurred mainly during the first 12 weeks of RTX treatment, with further DAS28-ESR improvement until week 24 or month 6 of re-treatment. Improvements in DAS28-ESR and EULAR responses were more pronounced in seropositive patients. RF was a predictor of DAS28-ESR change to study end. Safety analysis showed the established profile of RTX. CONCLUSION: RTX was safe and effective in a real-life setting with rapid and sustained improvement in RA signs and symptoms. PMID- 30276728 TI - Refractory chylous pleural effusion with systemic lupus erythematosus : Surgical treatment when steroid/immunosuppressant resistant. AB - We analyzed four cases of systemic lupus erythematosus (SLE) with chylous pleural effusion treated in our hospital from June 2013 to May 2017. The three females and one male ranged in age from 22 to 33 years. The length of disease course was 20 to 120 months. Treatment with glucocorticoids and immunosuppressants (cyclophosphamide or cyclosporine A) did not reduce chylous pleural effusion. Lymphatic obstruction was found in all patients after direct lymphangiography and the pleural effusion was significantly reduced after surgery. A literature search identified six previously reported patients with SLE and chylous pleural effusion. Five were sensitive to classic immunosuppression treatment, probably due to early intervention. However, as shown here, the thoracic duct can be involved in SLE, leading to an intractable chylous pleural effusion with no response to medical treatment. Surgery would be a better choice when lymphatic mechanical obstruction is found. PMID- 30276729 TI - Making the Case for Functional Proteomics. AB - "Making the Case for Functional Proteomics" first differentiates the Functional Proteome from the products of genetic protein expression. Qualitatively, the prevalence of posttranslational modifications (PTMs) virtually insures that individual, functional proteins do not equate to their genetic expression counterparts. Quantitatively, considering the frequency of PTMs and a conservative estimate of the number of functional entities arising from protein interactions, the size of the Functional Proteome exceeds that of the human genome by at least two orders of magnitude. The human genome does not, cannot, map the Functional Proteome. Further, the collective genome of the human microbiome dwarfs the human genome. With these facts established, "Making the Case..." proceeds to examine Functional Proteomics (of which both "gene expression" and "epigenetics" are but parts of a larger whole) within the context of Systems Biology, concluding that functionally related networks comprise the dominant motif for biological activity. Creating just such a network focus is essential in not only expanding basic knowledge but also in applying that knowledge in the pragmatic efforts of drug and biomarker development. Outlines for development of drugs and biomarkers, as well as the realization of precision medicine, within a functional proteomics-based, network motif are provided. The chapter proceeds to asses both the knowledge base and the tools to fully embrace Functional Proteomics. Given the decades-long infatuation with the reductionism of genomics, it is not surprising that both the proteomics knowledge base and tools are assessed as poor to fair. However, even a minor shift in research funding and a renewed challenge to methods developers will rapidly improve the current situation. Adoption of the included "Roadmap" will realistically make the twenty-first century the century of a long-awaited revolution in biology. PMID- 30276730 TI - Methods to Monitor the Functional Subproteomes of SERPIN Protease Inhibitors. AB - Conformational variants of the unique family of protease inhibitors annotated as SERPINs are most often underrepresented in proteomic analyses. This limits understanding the complex regulation that this family of proteins presents to the networks within the protease web of interactions. Using bead-based separation provided by a family of proteomic enrichment products-notably AlbuVoidTM and AlbuSorbTM, we demonstrate their utility to satisfy investigations of serum SERPINs. We also suggest their use to develop functional profiles of the SERPIN proteoforms, and how those can establish relationships to disease phenotypes, gene mutations, and dysregulated mechanisms. PMID- 30276731 TI - Two-Dimensional 16-BAC/SDS Polyacrylamide Gel Electrophoresis of Mitochondrial Membrane Proteins. AB - The substitution of the reverse polarity benzyldimethyl-n-hexadecylammonium chloride (16-BAC) polyacrylamide gel electrophoresis (PAGE) for isoelectric focusing (IEF) in the first dimension of electrophoresis improves the solubility of extremely hydrophobic proteins and their recovery compared to conventional 2D IEF/SDS PAGE. The acidic environment of 16-BAC PAGE has also been shown to better preserve the labile methylation of basic proteins such as the histones. Several improvements of the 2D 16-BAC/SDS PAGE method are collectively described here with particular emphasis on the separation of mitochondrial membrane proteins of low molecular mass. Lowering the 16-BAC concentration 50-fold in the gel and buffers decreases the formation of mixed 16-BAC/SDS micelles, which otherwise interferes with the separation of very low molecular mass proteins in second dimension SDS PAGE, and consequently improved the resolution of mitochondrial membrane proteins in the 10-30 kDa range. PMID- 30276732 TI - Systematic Glycolytic Enzyme Activity Analysis from Human Serum with PEP Technology. AB - A functional proteomics technology was used to systematically monitor metabolic enzyme activities from resolved serum proteins produced by a modified 2-D gel separation and subsequent Protein Elution Plate, a method collectively called PEP. Both qualitative and quantitative differences in the metabolic enzyme activity could be detected between cancer patient and control group, providing excellent biomarker candidates for cancer diagnosis and drug development. This technology has a wide range of applications; it can be used for rapid functional protein purification and characterization as well as drug target identification and validation. The ability for the PEP technology to efficiently separate and recover functional proteins makes it useful for the analysis of any proteins and its variants; this is especially advantageous for enzyme families with large number of enzymes such as protein kinases, phosphatases, proteases, and metabolic enzymes. PMID- 30276733 TI - A Protein Decomplexation Strategy in Snake Venom Proteomics. AB - Snake venoms are complex mixtures of proteins and peptides that play vital roles in the survival of venomous snakes. As with their diverse pharmacological activities, snake venoms can be highly variable, hence the importance of understanding the compositional details of different snake venoms. However, profiling venom protein mixtures is challenging, in particular when dealing with the diversity of protein subtypes and their abundances. Here we described an optimized strategy combining a protein decomplexation method with in-solution trypsin digestion and mass spectrometry of snake venom proteins. The approach involves the integrated use of C18 reverse-phase high-performance liquid chromatography (RP-HPLC), sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), and nano-electrospray ionization tandem mass spectrometry (nano-ESI-LC-MS/MS). PMID- 30276734 TI - Fractionation Techniques to Increase Plant Proteome Coverage: Combining Separation in Parallel at the Protein and the Peptide Level. AB - Peptide spectral libraries enable targeted identification and quantitation of low abundance proteins in a complex plant proteome. Here we describe parallel protein and peptide fractionation techniques to improve plant proteome coverage and facilitate construction of spectral libraries. PMID- 30276735 TI - A Systematic Analysis Workflow for High-Density Customized Protein Microarrays in Biomarker Screening. AB - High-density protein microarrays constitute a promising high-throughput platform for the characterization of protein expression patterns, biomarker discovery, and validation. Different types of protein microarrays have been described according to several features (such as content, format, and detection system) presenting advantages and disadvantages which are relevant for the specific application and purposes. Therefore, an experimental design is key for any screening based on protein microarrays assays; in fact, the data analysis strategy is directly related to the experimental design, type of protein microarray and consequently the final outcome, the data and results interpretation, is also directly linked. Here, it is proposed a systematic workflow for biomarker discovery based on tailor-made protein microarrays platforms which obtain comprehensively info for the functional protein characterization in high-throughput format. PMID- 30276736 TI - Metaproteomics Study of the Gut Microbiome. AB - Proteomics is a widely used method for defining the protein composition of a complex sample. As this approach allows for identification and quantification of proteins across a broad dynamic range as well as detection of post-translational modifications, proteomics is an ideal platform to investigate the gut microbiome at a functional level. The gut microbiome is a dynamic environment which is crucial for overall health and fitness. Imbalances in the gut microbiome can influence nutrient absorption, pathogen resistance, inflammation, and various human diseases. Metaproteomic analysis of the gut microbiome is currently being performed on bacteria isolated from (1) fecal samples (2) colonic lavage, or (3) colon biopsies. Investigation of the gut microbiome has demonstrated that within the colon, there are distinct communities based on spatial location, and separable from the gut microbiomes isolated from stool. In addition to expanding our understanding of host-bacterial interactions for human health and disease, gut microbiome analysis is being utilized for biomarker development to discriminate normal individuals and diseased (i.e., inflammatory bowel disease or colon cancer) patients as well as to monitor disease activity and prognosis. PMID- 30276737 TI - Double One-Dimensional Electrophoresis (D1-DE) Adapted for Immunoproteomics. AB - The classical proteomics approach for the identification of allergen candidates consists on the separation of proteins by high-resolution two-dimensional electrophoresis (2-DE) with subsequent IgE immunoblotting and further analysis of IgE-reactive protein spots with mass spectrometry. In this approach at least two gels most be run. One gel is used for staining and the other is for immunoblotting by antibodies labeled with specific immunostains. Additional functional characterizations require either protein purification or 2-DE replicates and appear to be time- and reagent-consuming. Here we described a modified double one-dimensional electrophoresis (D1-DE) allowing the conversion of a protein spot previously visualized by 2-DE into an extended protein band. In D1-DE, the purity of the protein of interest is similar to 2-DE spots, but its abundance is many times higher than what can be found in a 2-DE single spot allowing many other functional analyses from a single D1-DE separation. PMID- 30276738 TI - BioID: A Proximity-Dependent Labeling Approach in Proteomics Study. AB - Biological activities are mainly executed by proteins and in most of the occasions these activities are accomplished by protein complexes or through protein-protein interactions (PPI). So it is critical to reveal how the protein complexes are organized and demonstrate the PPIs involved in the biological processes. In addition to the traditional biochemical approaches, proximity dependent labeling (PDL) has recently been proposed to identify the interacting partners of a given protein. PDL requires the fusion expression of the target protein with an enzyme which catalyzes the attachment of a reactive molecule to the interacting partners in a distance-dependent manner. Further analysis of all the proteins that are modified by the reactive molecule discloses the identity of these proteins which are presumed to be interacting partners of the target protein. BioID is one of those representative PDL methods with the most widely applications. The enzyme used in BioID is a biotin ligase BirA which catalyzes the biotinylation of target protein with the presence of biotin. Through streptavidin-mediated pull-down and mass spectrometry analysis, the interacting protein candidates of a given protein can be obtained. PMID- 30276739 TI - Functional Application of Snake Venom Proteomics in In Vivo Antivenom Assessment. AB - Reverse-phase high-performance liquid chromatography is commonly employed as a decomplexing strategy in snake venom proteomics. The chromatographic fractions often contain relatively pure toxins that can be assessed functionally for toxicity level through the determination of their median lethal doses (LD50). Further, antivenom efficacy can be evaluated specifically against these venom fractions to understand the limitation of the antivenom as the treatment for snake envenomation. However, methods of toxicity assessment and antivenom evaluation vary across laboratories; hence there is a need to standardize the protocols and parameters, in particular those related to the neutralizing efficacy of antivenom. This chapter outlines the important in vivo techniques and data interpretation that can be applied in the functional study of snake venom proteomes. PMID- 30276740 TI - Proteomic Detection of Carbohydrate-Active Enzymes (CAZymes) in Microbial Secretomes. AB - Secretomes from microorganisms growing on biomass contain carbohydrate-active enzymes (CAZymes) of potential biotechnological interest. By analyzing such secretomes, we may discover key enzymes involved in degradation processes and potentially infer the mode-of-action of biomass conversion. Some of these enzymes may have predicted functions in carbohydrate degradation, while others may not, while yet exhibiting a similar expression pattern; these latter enzymes constitute potential novel enzymes involved in the degradation process and provide a basis for further biochemical exploration. Hence, secretomes represent an important source for the study of both predicted and novel CAZymes. Here we describe a plate-based culturing technique that allows for collection of protein fractions that are highly enriched for secreted proteins, bound or unbound to the substrate, and which minimizes contamination by intracellular proteins trough unwanted cell lysis. PMID- 30276741 TI - An Overview of Mass Spectrometry-Based Methods for Functional Proteomics. AB - The mechanism underlying many biological phenotypes remains unknown despite the increasing availability of whole genome and transcriptome sequencing. Direct measurement of changes in protein expression is an attractive alternative and has the potential to reveal novel processes. Mass spectrometry has become the standard method for proteomics, allowing both the confident identification and quantification of thousands of proteins from biological samples. In this review, mass spectrometry-based proteomic methods and their applications are described. PMID- 30276742 TI - Functional Proteomic Analysis to Characterize Signaling Crosstalk. AB - The biological activities of a cell are determined by its response to external stimuli. The signals are transduced from either intracellular or extracellular milieu through networks of multi-protein complexes and post-translational modifications of proteins (PTMs). Most PTMs including phosphorylation, acetylation, ubiquitination, and SUMOylation, among others, modulate activities of proteins and regulate biological processes such as proliferation, differentiation, as well as host pathogen interaction. Conventionally, reverse genetics analysis and single molecule-based studies were employed to identify and characterize the function of PTMs and enzyme-substrate networks regulated by them. With the advent of high-throughput technologies, it is now possible to identify and quantify thousands of PTM sites in a single experiment. Here, we discuss recent advances in enrichment strategies of various PTMs. We also describe a method for the identification and relative quantitation of proteins using a tandem mass tag labeling approach combined with serial enrichment of phosphorylation, acetylation and succinylation using antibody enrichment strategy. PMID- 30276743 TI - Identification of Unexpected Protein Modifications by Mass Spectrometry-Based Proteomics. AB - Peptide identification relies in the majority of mass spectrometry-based proteomics experiments on matching of experimental data against peptide and fragment ion masses derived from in silico digests of protein databases. One of the main drawbacks of this approach is that modifications have to be defined for database searching and therefore no unexpected modifications can be identified in a standard setup. Consequently, in many bottom-up proteomics experiments, unexpected modifications are not identified, even if high-quality fragment ion spectra of the modified peptides were acquired. It is therefore often not straightforward to identify unexpected modifications. In this protocol, we describe a stepwise procedure to identify unexpected modifications at peptides using the database search algorithm Mascot. The workflow includes parallel searches for the identification of known modifications at unexpected amino acids, error tolerant searches for modifications unexpected in the sample but known to the community, and mass tolerant searches for entirely unknown modifications. Furthermore, we suggest a follow-up strategy consisting of (1) verification of identified modifications in the initial dataset and (2) targeted experiments using synthetic peptides. PMID- 30276744 TI - Label-Free LC-MS/MS Strategy for Comprehensive Proteomic Profiling of Human Islets Collected Using Laser Capture Microdissection from Frozen Pancreata. AB - Diabetes mellitus is caused by either loss of pancreatic islets beta-cells (Type 1 Diabetes, T1D), insufficient insulin release in the islet beta-cells coupled with insulin resistance in target tissues (Type 2 Diabetes, T2D), or impaired insulin release (genetic forms of diabetes and, possibly, T1D subtypes). The investigation of the islet proteome could elucidate facets of the pathogenesis of diabetes. Enzymatically isolated and cultured (EIC) islets are frequently used to investigate biochemical signaling pathways that could trigger beta-cell changes and death in diabetes. However, they cannot fully reflect the natural protein composition and disease process of in vivo islets due to the stress from isolation procedures and in vitro culture. The laser capture microdissection method employs a high-energy laser source to separate the desired cells from the remaining tissue section in an environment which is well conserved and close to the natural condition. Here, we describe a label-free proteomic workflow of laser capture microdissected (LCM) human islets from fresh-frozen pancreas sections of cadaveric donors to obtain an accurate and unbiased profile of the pancreatic islet proteome. The workflow includes preparation of frozen tissue section, staining and dehydration, LCM islets collection, islet protein digestion, label free Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS), database search, and statistical analysis. PMID- 30276745 TI - Targeted Proteomics. AB - Targeted proteomics detects proteins of interest with high sensitivity, quantitative accuracy, and reproducibility. In a targeted proteomics assay, surrogate peptides are generated by proteolytic digestion of target proteins and selected reaction monitoring (SRM) assays are developed to quantify these peptides using liquid chromatography-tandem mass spectrometry (LC-MS/MS). In this report, we describe the details of quantitative analysis of target protein in cells and tissue samples. PMID- 30276746 TI - Metabolomic Investigation of Staphylococcus aureus Antibiotic Susceptibility by Liquid Chromatography Coupled to High-Resolution Mass Spectrometry. AB - Staphylococcus aureus is a major human pathogen that can readily acquire antibiotic resistance. For instance, methicillin-resistant S. aureus represents a major cause of hospital- and community-acquired bacterial infections. In this chapter, we first provide a detailed protocol for obtaining unbiased and reproducible S. aureus metabolic profiles. The resulting intracellular metabolome is then analyzed in an untargeted manner by using both hydrophilic interaction liquid chromatography and pentafluorophenyl-propyl columns coupled to high resolution mass spectrometry. Such analyses are done in conjunction with our in house spectral database to identify with high confidence as many meaningful S. aureus metabolites as possible. Under these conditions, we can routinely monitor more than 200 annotated S. aureus metabolites. We also indicate how this protocol can be used to investigate the metabolic differences between methicillin resistant and susceptible strains. PMID- 30276747 TI - Nuts and Bolts of Protein Quantification by Online Trypsin Digestion Coupled LC MS/MS Analysis. AB - Protein digestion coupled to liquid chromatography and tandem mass spectrometry (LC-MS/MS) detection enables multiplexed quantification of proteins in complex biological matrices. However, the reproducibility of enzymatic digestion of proteins to produce proteotypic target peptides is a major limiting factor of assay precision. Online digestion using immobilized trypsin addresses this problem through precise control of digestion conditions and time. Because online digestion is typically for a short time, the potential for peptide degradation, a major source of measurement bias, is significantly reduced. Online proteolysis requires minimal sample preparation and is easily coupled to LC-MS/MS systems, further reducing potential method variability. We describe herein a method optimized for the multiplexed quantification of several apolipoproteins in human serum using on-column digestion. We highlight key features of the method that enhance assay accuracy and precision. These include the use of value-assigned serum as calibrators and stable isotope-labeled (SIL) peptide analogs as internal standards. We also comment on practical aspects of column switching valve design, instrument maintenance, tandem mass spectrometry data acquisition, and data processing. PMID- 30276748 TI - Proteases: Pivot Points in Functional Proteomics. AB - Proteases drive the life cycle of all proteins, ensuring the transportation and activation of newly minted, would-be proteins into their functional form while recycling spent or unneeded proteins. Far from their image as engines of protein digestion, proteases play fundamental roles in basic physiology and regulation at multiple levels of systems biology. Proteases are intimately associated with disease and modulation of proteolytic activity is the presumed target for successful therapeutics. "Proteases: Pivot Points in Functional Proteomics" examines the crucial roles of proteolysis across a wide range of physiological processes and diseases. The existing and potential impacts of proteolysis-related activity on drug and biomarker development are presented in detail. All told the decisive roles of proteases in four major categories comprising 23 separate subcategories are addressed. Within this construct, 15 sets of subject-specific, tabulated data are presented that include identification of proteases, protease inhibitors, substrates, and their actions. Said data are derived from and confirmed by over 300 references. Cross comparison of datasets indicates that proteases, their inhibitors/promoters and substrates intersect over a range of physiological processes and diseases, both chronic and pathogenic. Indeed, "Proteases: Pivot Points ..." closes by dramatizing this very point through association of (pro)Thrombin and Fibrin(ogen) with: hemostasis, innate immunity, cardiovascular and metabolic disease, cancer, neurodegeneration, and bacterial self-defense. PMID- 30276749 TI - The Use of Combinatorial Hexapeptide Ligand Library (CPLL) in Allergomics. AB - The recent progress of proteomic protocols led to more efficient protein extraction and concentration procedures to remove nonprotein interfering compounds present in the starting material and to increase the concentration of underrepresented proteins. Combinatorial hexapeptide ligand libraries (CPLL) were recently applied to both plant- and animal-derived tissues for capturing the low- and very low-abundance allergens. Several IgE-binding proteins which were previously absent or poorly represented by using conventional proteomics tools have been detected and characterized through a CPLL-based approach. In the present chapter, a protocol based on improved protein extraction and enrichment by CPLL, allowing the immunochemical characterization of several "hidden allergens" in cypress pollen, is described in detail. PMID- 30276750 TI - Efficient Extraction and Digestion of Gluten Proteins. AB - Coeliac disease (CD) is a T-cell mediated autoimmune disorder triggered by ingestion of cereal gluten found in wheat (gliadins and glutenins), barley (hordeins), and rye (secalins). As the only treatment for CD is a lifelong gluten free diet, the measurement of gluten in raw ingredients and processed food products is critical to protecting people with CD or gluten intolerance. The most commonly employed method is the enzyme-linked immunosorbent assay (ELISA), but more recently mass spectrometry has been employed wherein the extracted gluten proteins are digested to peptides that are then directly measured. To achieve the goal of accurate gluten quantitation, gluten must be efficiently extracted from the ingredient or food matrix and then digested to yield the peptides that are monitored by LC-MS. In this chapter, a rapid, simple, and reproducible protocol for extraction and digestion of gluten proteins is described. PMID- 30276751 TI - Glycosylation Profiling of Tumor Marker in Plasma Using Bead-Based Immunoassay. AB - As one of the most important posttranslational modifications, glycosylation plays critical roles in protein folding, trafficking, cell differentiation, immune recognition, etc. The alteration of glycosylation is closely associated with the pathological processes during and after caner development, and thus holds great value in cancer detection. In this chapter, we describe a protocol on the glycosylation profiling of tumor marker in plasma using bead-based immunoassay with CA125 as a model, including bead coupling, coupling control, glycosylation assay, as well as the plasma screening for breast cancer patients. This protocol can be used to profile the glycosylation of protein markers in clinical plasma or serum samples for different human cancers. PMID- 30276752 TI - Protein-Specific Analysis of Invertebrate Glycoproteins. AB - N-Glycans are posttranslational modifications of proteins attached to the amide side chains of asparagine residues, with possible heterogeneity due to different structures being possible at the same glycosylation site. In contrast to the mammalian systems, invertebrate N-glycosylation presents a challenge in analysis as there exist unfamiliar epitopes and a high degree of structural and isomeric variation between different species. A simple analytical approach to analyze N glycans on specific glycoproteins is presented, which involves a combination of tryptic peptide mass spectrometry and "off-line" RP-HPLC MALDI-TOF MS/MS complemented by blotting to recognize specific epitopes. An additional N-glycan enrichment and labeling step can facilitate the analysis of single structures and even provide isomeric separation of N-glycans from specific proteins. PMID- 30276753 TI - The Use of Proteomics Studies in Identifying Moonlighting Proteins. AB - Proteomics studies that characterize hundreds or thousands of proteins in parallel can play an important part in the identification of moonlighting proteins, proteins that perform two or more distinct and physiologically relevant biochemical or biophysical functions. Functional assays, including ligand-binding assays, can find a surprising second function for a protein that was previously identified as performing a different function, for example, a DNA-binding ability for an enzyme in amino acid metabolism. The results of large-scale assays of protein-protein interactions, gene knockouts, or subcellular protein localizations, or bioinformatics analysis of amino acid sequences and three dimensional structures, can also be used to predict that a protein has additional functions, but in these cases it is important to use biochemical and biophysical methods to confirm the protein can perform each function. PMID- 30276754 TI - Two-Dimensional Biochemical Purification for Global Proteomic Analysis of Macromolecular Protein Complexes. AB - A high-resolution two-dimensional (2-D) proteomic fractionation technique for the systematic purification and subsequent mass spectrometry-based identification of endogenous protein macromolecular complexes is described. The method hyphenates preparative isoelectric focusing (IEF) with mixed-bed ion exchange chromatography (IEX) to efficiently separate cell- or tissue- derived soluble protein mixtures, allowing for more effective and less biased physiochemical characterization of stable multiprotein assemblies. After comprehensive 2D fractionation of cell-free lysates, each fraction is subjected to quantitative tandem mass spectrometry (MS/MS) and subsequent computational analysis to map high-confidence protein protein interactions (PPIs). Herein, the experimental component (workflow protocols) for this global "interactome" network mapping platform is described. PMID- 30276755 TI - A Data Analysis Protocol for Quantitative Data-Independent Acquisition Proteomics. AB - Data-independent acquisition (DIA) mode of mass spectrometry, such as the SWATH MS technology, enables accurate and consistent measurement of proteins, which is crucial for comparative proteomics studies. However, there is lack of free and easy to implement data analysis protocols that can handle the different data processing steps from raw spectrum files to peptide intensity matrix and its downstream analysis. Here, we provide a data analysis protocol, named diatools, covering all these steps from spectral library building to differential expression analysis of DIA proteomics data. The data analysis tools used in this protocol are open source and the protocol is distributed at Docker Hub as a complete software environment that supports Linux, Windows, and macOS operating systems. PMID- 30276756 TI - Early detection of memory impairments in older adults: standardization of a short version of the verbal and nonverbal Recognition Memory Test. AB - In several neurological conditions, in elderly and cognitively impaired subjects, memory functioning must be evaluated to early detect the cognitive deterioration processes. In particular, recognition memory assessment is an essential step in the clinical and neuropsychological evaluation of early memory impairments. The Recognition Memory Test (RMT) developed by Smirni et al. (G Ital Psicol XXXVII(1):325-343, 2010) is an effective instrument to assess verbal and nonverbal recognition memory in the Italian population. The current study provides a new, brief, and reliable RMT format to evaluate recognition memory on elderly subjects and it reports normative data in an older adult Italian population sample (including 100 participants well distributed across sex, education, and age categories). The shortened version of RMT keeps the administration procedures and materials of the original Italian RMT constant, i.e., words, faces, and buildings. Multiple regression analysis revealed significant effects of age and educational level on performance but no effect of sex. Inferential cutoffs have been determined and equivalent scores computed. The availability of equivalent scores for the Recognition Memory Test will prove useful in the clinical evaluation of patients' memory profiles. PMID- 30276757 TI - Analyte-triggered cyclic autocatalytic oxidation amplification combined with an upconversion nanoparticle probe for fluorometric detection of copper(II). AB - The authors describe an upconversion nanoparticle-based (UCNP-based) fluorometric method for ultrasensitive and selective detection of Cu2+. The UCNPs show a strong emission band at 550 nm under near-infrared excitation at 980 nm. The principle of the strategy is that gold nanoparticles (AuNP) can quench the fluorescence of UCNP. In contrast, the addition of L-cysteine (Cys) can induce the aggregation of AuNP, resulting in a fluorescence recovery of the UCNPs. On addition of Cu2+, it oxidizes Cys to cystine and is reduced to Cu+. The Cu+ thusformed can be oxidized cyclically to Cu2+ by dissolved O2, which catalyzes and recycles the whole reaction. Thus, the aggregation of AuNP is inhibited and the fluorescence recovered by Cys is quenched. Under the optimal condition, the quenching efficiency shows a good linear response to the concentrations of Cu2+ in the 0.4-40 nM range. The limit of detection is 0.16 nM, which is 5 orders of magnitude lower than the U.S. Environmental Protection Agency limit for Cu2+ in drinking water (20 MUM). The method has been further applied to monitor Cu2+ levels in real samples. The results of detection are well consistent with those obtained by atomic absorption spectroscopy. Graphical abstract Gold nanoparticles (AuNP) as a high efficient fluorescence quenching reagent of upconversion nanoparticles (UCNP) were used in a fluorometric method for detection of Cu2+ based on a cyclic catalytic oxidation amplification strategy. PMID- 30276758 TI - Toxic Peptides in Populations of Two Pergid Sawflies, Potential Biocontrol Agents of Brazilian Peppertree. AB - Determination of the safety of agents prior to release is one of the most important research goals in biological control. In addition to concerns for the safety of non-target plants, determination of the potential toxic properties of new agents needs to be assessed. Numerous phytophagous insects are defended by chemicals against the attack of natural enemies. Some of these defensive compounds could pose an environmental risk if an agent is released. Here, larval populations of two pergid sawflies, Heteroperreyia hubrichi and H. jorgenseni, were analyzed by LC-MS/MS to investigate whether they contain alleged toxic peptides. The first species is a potential candidate for biological control of the invasive weed Brazilian peppertree in Florida and Hawaii. The chemical analyses revealed the presence of the peptides pergidin (Perg), 4-valinepergidin (VPerg), dephosphorylated pergidin (dpPerg), lophyrotomin (LGln and LGlu). The effect of sawfly population for each species was significantly influencing peptide concentration. All peptides occurred at lower concentrations compared with purportedly toxic species of this sawfly family. However, the concentrations of the peptides are of concern for the welfare of wildlife and livestock that would be exposed to these species. These results demonstrate that release of this biological control agent in the invaded range may pose an environmental threat. PMID- 30276759 TI - Efficacy of Huaier granule in patients with breast cancer. AB - BACKGROUND: Huaier extract has been demonstrated to exhibit potent anti-tumor effects in various types of cancer cells. However, the clinical benefit of Huaier granule in breast cancer has not been reported. In this study, we aimed to evaluate the efficacy of Huaier granule in breast cancer patients. METHODS: Our study included 284 breast cancer patients treated with or without Huaier granule between January 2005 and October 2016 at Qilu Hospital, Shandong University, Jinan, China. Retrospective data obtained included demographics, clinicopathological characteristics, disease-free survival (DFS), serum concentrations of tumor markers, the Karnofsky performance scale (KPS), and incidences of emotional symptoms. DFS was the main outcome measure. RESULTS: Of the patients included, 144 were classified into the control group and 140 into the Huaier group. Baseline characteristics were well balanced between the study arms. Median DFS was 91.43 months for control group and 112.61 months for Huaier group (hazard ratio (HR) = 2.97, 95% confidence interval (CI) = 1.57-5.61, p < 0.01). After Huaier granule treatment, the serum levels of tumor markers could be reduced to the normal range. In addition, breast cancer patients with Huaier granule treatment had higher KPS scores and less emotional symptoms. CONCLUSIONS: Our data demonstrated that patients orally administrated Huaier granule got longer DFS. Furthermore, Huaier granule could reduce serum tumor markers, improve the functional status, and decrease the incidences of emotional symptoms in breast cancer patients. Therefore, Huaier granule was an effective therapy for women with breast cancer.

There was a typo in the second sentence of the paragraph under the section Was the Dose of Drugs Fair?; "320 mg twice a day" should read "160mg twice a day". The corrected paragraph is shown below. PMID- 30276761 TI - Bio-artificial bone formation model with a radial-flow bioreactor for implant therapy-comparison between two cell culture carriers: porous hydroxyapatite and beta-tricalcium phosphate beads. AB - Bone grafting is necessary before dental implant treatment in patients with jaw bone defects. Currently, autologous bone grafting is a major burden on the patient. However, it is impossible to form a sufficient foundation for the implant with a bone-filling agent alone. It is, therefore, necessary to prepare hybrid artificial bone tissue containing osteoblasts and osteoclasts. In this study, mouse MC3T3-E1 pre-osteoblast cells and human embryonic-derived osteoblastic cell line hFOB1.19 were cultured in radial-flow bioreactors (RFB) to form three-dimensional artificial bone filled with porous beads of beta tricalcium phosphate (beta-TCP) or hydroxyapatite (HA)-which are clinically used as bone-filling agents-as cell culture carriers. When circulation culturing was performed in the growth medium for the first 10-12 days, glucose consumption was increased in the cultures with HA beads in comparison to the cultures with beta TCP beads. When cultured in the differentiation culture medium during the second half of the culture period, the glucose consumption decreased in the culture with HA beads. A DNA microarray analysis suggested that osteogenesis progressed fast in three-dimensional culture filled with HA beads and that partly differentiation into osteoblasts was prominent in cultures with beta-TCP beads. In the growth process of MC3T3-E1 cells, the vitamin A metabolism was also activated, the synthesis and degradation of retinoic acid was enhanced, and the metabolism of the same process decreased at the end of differentiation in three-dimensional cultures. Three-dimensional circulation culture in RFB is considered to be useful for the formation of hybrid bio-artificial bone tissue. PMID- 30276762 TI - TRK Inhibition: A New Tumor-Agnostic Treatment Strategy. AB - Oncogenic somatic chromosomal rearrangements involving the NTRK1, NTRK2 or NTRK3 genes (NTRK gene fusions) occur in up to 1% of all solid tumors, and have been reported across a wide range of tumor types. The fusion proteins encoded by such rearranged sequences have constitutively activated TRK tyrosine kinase domains, providing novel therapeutic anticancer targets. The potential clinical effectiveness of TRK inhibition in patients with tumors harboring NTRK gene fusions is being assessed in phase I and II trials of TRK inhibitors, such as larotrectinib and entrectinib. Clinical trial results have demonstrated that larotrectinib is generally well tolerated and has shown high response rates that are durable across tumor types. These data validate NTRK gene fusions as actionable genomic alterations. In this review, we present the clinical data, discuss the different approaches that might be used to routinely screen tumors to indicate the presence of NTRK gene fusions, explore the issue of acquired resistance to TRK inhibition, and reflect on the wider regulatory considerations for tumor site agnostic TRK inhibitor drug development. PMID- 30276763 TI - Sustained prognostic impact of circulating tumor cell status and kinetics upon further progression of metastatic breast cancer. AB - PURPOSE: Serial longitudinal enumeration of circulating tumor cells (CTCs) has shown its prognostic value on progression-free survival and overall survival (OS) in patients with stage IV breast cancer. This study prospectively evaluated the role of CTCs as a prognostic marker during further progression of metastatic breast cancer (MBC). METHODS: Among 476 MBC patients recruited between 2010 and 2015, the 103 patients with a known CTC status at baseline (CTCBL) and within 4 weeks of tumor progression (CTCPD) were included. Progressive disease (PD) was defined according to the Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1). Using the CellSearch method, < 5 and >= 5 CTCs per 7.5 ml blood were determined as negative and positive, respectively. A shift in CTC status from baseline to progression ([Formula: see text] to [Formula: see text] and vice versa) was considered as alternating KineticsBL-PD. RESULTS: Median follow-up was 29.9 [21.2, 40.0] months. CTCPD positivity (37%, n = 38) was associated with a significantly shorter OS than CTCPD negativity (8.0 [5.1, 10.9] vs 22.6 [15.3, 39.8] months; P < 0.001). Alternating KineticsBL-PD was observed in 24% of the patients. This significantly changed the OS prediction of [Formula: see text] patients ([Formula: see text] vs [Formula: see text], 11.4 [9.7, not available (NA)] vs. 7.6 [4.4, 11.5] months; P = 0.044) and [Formula: see text] patients ([Formula: see text] vs. [Formula: see text], 8.4 [4.0, NA] vs. 22.6 [18.9, NA] months, respectively; P < 0.001). Prediction of survival was significantly improved (P = 0.002) by adding CTCPD status to clinicopathological characteristics and CTCBL status. CONCLUSIONS: CTC status upon further disease progression is a prognostic factor that could significantly improve well established models. Thus, it represents a potential additional instrument supporting treatment decision. PMID- 30276764 TI - Prediction of Schizophrenia Diagnosis by Integration of Genetically Correlated Conditions and Traits. AB - Schizophrenia is genetically heterogeneous and comorbid with many conditions. In this study, we explored polygenic scores (PGSs) from genetically related conditions and traits to predict schizophrenia diagnosis using both logistic regression and deep neural network (DNN) models. We used the combined Molecular Genetics of Schizophrenia and Swedish Schizophrenia Case Control Study (MGS + SSCCS) data for training and testing the models, and used the Clinical Antipsychotic Trials for Intervention Effectiveness (CATIE) data as independent validation. We screened 28 conditions and traits comorbid with schizophrenia to identify traits as potential predictors and used LASSO regression to select predictors for model construction. We investigated how PGS calculation influenced model performance. We found that the inclusion of comorbid traits improved model performance and PGSs calculated from two traits were more generalizable in independent validation. With a DNN model using 19 PGS predictors, we accomplished a prediction accuracy of 0.813 and an AUC of 0.905 in the MGS + SSCCS data. When this model was validated with the CATIE data, it achieved an accuracy of 0.721 and AUC of 0.747. Our results indicate that PGSs alone may not be sufficient to predict schizophrenia accurately and the inclusion of behavioral and clinical data may be necessary for more accurate prediction model. PMID- 30276766 TI - [Health Without Boundaries]. AB - 'Sow in spring, grow through the summer, harvest in autumn, store in winter' reflects the ancient wisdom of the Chinese people, passed down for thousands of years. As this year comes to a close, this journal would like to pause to recognize that Taiwan's national health insurance system has been looking after and caring for the health of Taiwan's people for more than 20 years. What can we do to better follow global care trends and to perform better for public health in Taiwan? Many thanks to Director Wang of the Health Promotion Administration for introducing to readers the concept of 'health without boundaries' and examining Taiwan's future healthcare blueprint from a global perspective. In addition, under the influence of fast-changing medical technologies and rising life expectancies, the increase in the population with chronic diseases prompted Health Promotion Administration's Chronic Disease Division Chief Jia Shuli to provide a comprehensive description of his division's work, from developing chronic disease self-care regimens to developing follow-up control protocols. Professor Lin, with years of diabetes prevention, treatment and innovative experience, has also written an article for this issue that explains why health professionals should go beyond dealing with diseases in order to listen, cooperate with, and interact with patients in order to expand the adoption and effectiveness of diabetes self-management programs. Finally, Professor Guo's article stresses the importance of promoting a healthy environment by going beyond focusing on one's health to address the improvement of the overall environment in order to shape the urban health landscape and achieve A+ health quality. In these cold winter days, brew a pot of hot tea and let us taste together these rare journeys of wisdom. PMID- 30276765 TI - Distal pancreatectomy with autologous islet transplantation in chronic pancreatitis patients: First case series from India. AB - Pancreatectomy and autologous islet transplantation (AIT) are performed in highly specialized centers to alleviate abdominal pain and preserve endocrine function in patients with chronic pancreatitis. We aimed at initiating AIT studies in India for the first time in patients undergoing distal pancreatectomy (DP) to prevent development of diabetes. Four out of 14 chronic pancreatitis patients screened underwent DP with AIT. Pancreatectomy specimen preserved in Wisconsin solution was subjected to islet isolation employing standard protocol using collagenase V. Isolated islets were infused into the liver through portal vein after quality assessment and the four patients were followed for 1 year. During the study period, blood glucose, fasting insulin, and C-peptide were analyzed and glucose tolerance was assessed. Three patients could be infused with islets (4363 Islet equivalents, IEQ/kg, 3860 IEQ/kg, 3600 IEQ/kg) into liver without any infusion-related complications. Two of these patients maintained glucose tolerance and glycemic control (HbA1c: 6.0%) and one became diabetic at the end of 1 year (HbA1c: 7.5%). Circulating fasting insulin increased (2.7-24.4 MUU/mL and 4.0-21.2 MUU/mL) and C-peptide levels increased (2.2 to 3.6, 3.4-5.6 ng/mL) in these two patients. Circulating insulin was 2.7 MUU/mL and C-peptide was 2.4 ng/mL in the patient who became diabetic at the end of 1 year, while insulin was 2.3 MUU/mL and C-peptide was 1.2 ng/mL in the patient who could not be infused with islets after DP. Safety and feasibility of autologous islet transplantation is established in India for the first time. PMID- 30276767 TI - [Health Promotion Policies for All in Taiwan]. AB - Health promotion was defined at the first International Conference on Health Promotion held by the World Health Organization in 1986 as a process that enables the public to improve their health. Moreover, the United Nations High-Level Meeting on the Prevention and Control of Non-Communicable Diseases in 2011 highlighted that non-communicable diseases (NCDs) account for 63% of deaths worldwide, with major NCD-related risk behaviors including tobacco use, physical inactivity, the harmful use of alcohol, and unhealthy diet. In 2013, the WHO announced the Global Action Plan for the Prevention and Control of NCDs 2013 2020, with the United Nations listing NCDs prevention and control as a major topic for nations in Sustainable Development Goal 3 (Health). Both Taiwan and the world face the dual threats of population aging and NCDs, adding to the importance of health promotion and NCDs prevention and control. This article first introduces the relevant global health trends and the corresponding status of Taiwan and then examines the major NCDs prevention and health promotion policies in Taiwan. In creating a health-supportive environment for all people and enhancing health literacy and empowerment among the general public, we hope to ensure that every individual, family, and city joins the ongoing effort in Taiwan to enable all individuals to make the best, informed decisions for their health. PMID- 30276768 TI - [Chronic Disease Prevention: Present and Future]. AB - Non-communicable diseases (NCDs) have risen to become a major threat to health worldwide. According to the World Health Organization, NCDs accounted for 68% of all global mortality in 2014, with over 40% of NCD-related mortality incidents defined as premature deaths under the age of 70 years. Among the top-10 causes of death named by the Taiwan Ministry of Health and Welfare in 2017, 28% were cancers, 22.3% were cardiovascular diseases, 5.7% were diabetes, and 3.6% were chronic obstructive pulmonary diseases. These four major NCDs currently account for nearly 60% of all mortalities in Taiwan and reflect the threat of NCDs to global health. Taiwan's increasingly ageing society faces an increasing risk of NCDs, which threatens the health and wellbeing of Taiwan's population. A survey by the Health Promotion Administration in 2013 found that over 80% of senior citizens in Taiwan are afflicted with one or more NCD and that the presence of a comorbidity further exacerbates the problem of living and coping with NCDs. This article introduces the primary, secondary, and tertiary public health prevention measures related to NCDs in order to help caregivers better understand the importance of reducing the risk factors of NCDs and of screening to promote early detection and treatment. This article further proposes a systemic framework for the future care of NCDs. PMID- 30276769 TI - [From Monologue to Dialogue: The Evolution of Diabetes Self-Management Education]. AB - Diabetes is a chronic disease. Patients with diabetes must actively change their eating and exercise habits and cannot rely solely on medication. Moreover, these patients need to control high blood glucose, high blood pressure, and high blood cholesterol, commonly known as control of the "three highs". As the current state of diabetes control is not ideal in the United States and Taiwan, disease-related complications such as blindness and the need for dialysis is expected to continue to increase in these countries in the future. This article highlights the possible factors of poor control of the "three highs" such as the therapeutic inertia of physicians (also known as clinical inertia), patient adherence, and current challenges in diabetes self-management education. In the past, courses in health education at our institution have been frequently delivered in monologue format. In recent years, we have tried a form of group therapy known as shared medical appointment (SMA) in order to encourage dialogue among patients and minimize didactic teaching. The preliminary results have been promising. In recent weeks, we began to discuss targeting SMA therapy on the topics of food metabolism and the typical effects and side effects of new and old drugs. We hope this will ease our introduction of shared decision making (SDM) in the near future. Promoting time-consuming procedures such as SDM is difficult in Taiwan because national-insurance health insurance payments to the healthcare provider are based on volume rather than value. We hope that the Health Insurance Bureau begins to recognize and appreciate the contribution of nurse educators and dietitians in the care of patients with diabetes and approve compensation for their hard work. PMID- 30276770 TI - [Health Without Borders: Creating Healthy Cities]. AB - Urbanization, a rapidly rising trend worldwide, is being felt particularly strongly in East Asia. The World Health Organization (WHO) launched a healthy cities plan in 1986 as a platform to encourage cities around the world to eliminate the problems resulting from increasingly dense urban population densities. The health and quality of life of city residents are seriously affected by the problems associated with urbanization, including environmental pollution, traffic congestion, public insecurity, and inadequate infrastructure, which may exceed the scope of local government plans and expectations. Rather than dealing with these problems individually, urban planners must take a global approach to issue of urbanization. Public and private-sector inputs are critical to facilitating good urban planning and community development by local governments in order to help cities achieve a well-managed urban environment that gives citizens a good environment in which to live, work, and play. The promotion healthy-city plans in Taiwan will foster the creation of cities of health through the integration or cooperation of government health, urban-planning, environmental-protection, industrial-development, transportation, cultural education, and other departments and agencies. Based on the vision of a healthy city, Taiwan's cities should gradually attain a sustainable, healthy society and healthy environment that promotes the holistic health of their residents. Therefore, we look forward to fulfilling the vision of "health without borders, creating healthy cities" through the implementation of the healthy city plan.

AB - BACKGROUND: Evidence-based research has shown the effects of traditional Chinese exercise on exercise capacity, depression, and quality of life in patients with cardiovascular disease. However, the effects of Chan-Chuang qigong on the physical and psychological status and on the quality of life of these patients are unknown. PURPOSE: To investigate the effects of Chan-Chuang qigong on exercise capacity, depression, and quality of life in patients with heart failure. METHODS: A randomized controlled study with repeated measures was conducted. One hundred participants with heart failure were recruited from a teaching medical center in Taiwan. Permuted block randomization was used to randomly assign the participants to either the Chan-Chuang qigong group, which received Chan-Chuang qigong intervention for three-months, or the control group. The outcome variables included six-minute walk distance, depression, and quality of life. RESULTS: Generalized estimating equation analyses showed that the Chan Chuang qigong group achieved significantly greater improvements than the control group in terms of six-minute walk distance (p = .001, p < .001, p < .001, respectively) and quality of life (p = .016, p < .001, p < .001, respectively) at 2, 4, and 12 weeks after the intervention and depression at 12 weeks after the intervention (p = .016). CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The results of this study indicate that Chan-Chuang qigong improves exercise capacity, depression, and quality of life in patients with heart failure without imposing harmful side effects. PMID- 30276772 TI - [The Relationship Between Diet Nutrition Knowledge and Demographic Characteristics in Family Caregivers of Patients With Dementia]. AB - BACKGROUND: Although the general-care knowledge of family caregivers related to dementia had been studied, little attention has been given to understanding the knowledge of caregivers related to dementia diet nutrition. This knowledge is important to help caregivers handle the eating and nutrition problems of people with dementia (PwD). PURPOSE: The purpose of this study was to explore the dementia diet nutrition knowledge of family primary caregivers and to analyze whether demographic characteristics of caregivers and/or the dementia stages of PwD have a relationship with dementia diet nutrition knowledge. METHODS: A descriptive and cross-sectional study using a questionnaire survey was conducted. A total of 220 primary family caregivers of people with dementia were recruited. RESULTS: Results showed that the average total score for the 13 questions on diet nutrition knowledge was 71.85%. Moreover, only 28.2% of the participants answered the question "Malnutrition is a significant risk during the early stage of dementia" correctly. In addition, the findings showed significant differences in the diet nutrition knowledge of participants based on education level (F = 3.989, p < .05) and the use of foreign (non-Taiwanese) caregivers (t = -2.919, p < .01). CONCLUSIONS: The participants had sufficient overall diet nutrition knowledge of dementia. However, they lacked knowledge in specific areas. Family caregivers with higher levels of education and those who hired foreign caregivers had better knowledge scores. The results may be used as a reference for nurses providing dementia dietary education. It is recommended that special attention be given to dietary education when patients are at the early onset phase of the disease and when caregivers have a lower level of education in order to improve the overall quality of dementia dietary care in the community. PMID- 30276773 TI - [Exploring Resilience and Related Factors Among Patients With Stroke in the Recovery Stage]. AB - BACKGROUND: Resilience is known to affect the degree to which individuals adapt to the impact of stroke and its sequelae. However, few studies have examined resilience and related factors among stroke patients in Taiwan. PURPOSE: To explore resilience and related factors among stroke patients in the recovery stage. METHODS: A cross-sectional and correlational study design was adopted. Convenience sampling was employed to recruit participants from the rehabilitation inpatient wards of a regional teaching hospital in northern Taiwan. A structured questionnaire, including the social support scale and the Chinese version of the resilience scale, was used for data collection. Data were analyzed using descriptive and inferential statistics and stepwise regression analysis. RESULTS: A total of 128 stroke recovery in-patients who averaged 57.2 +/- 11.6 years of age and were predominantly male were recruited. The results of this study showed that the global resilience of participants was moderate and that a significantly positive correlation existed between global social support and resilience. Age, marital status, and global tangible social support accounted for 25.0% of the total variation in resilience. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: Age, marital status and global tangible social support were identified as the crucial predictive factors of resilience in stroke patients. The results support the recommendation that healthcare providers should acquire advanced knowledge and skills through in-service education, proactive caring, and encouraging patients to learn self-care in order to enhance rehabilitation motivation and confidence levels and subsequently promote disease recovery and the ability to adapt to life through cross-disciplinary medical team cooperation and supportive relationships. PMID- 30276774 TI - [Risk Factors of Retained Central Venous Catheter Associated Bloodstream Infections in Hospitalized Patients]. AB - BACKGROUND: Despite recent efforts in Taiwan to reduce the risk and incidence of central venous catheter associated bloodstream infections (CABSI), the results as reported by the Taiwan Centers for Disease Control, when compared with the results achieved in the USA, indicate that Taiwan must promote the central venous catheter bundle approach more effectively. Furthermore, the risk factors for CABSI should be explored further in order to facilitate the development and implementation of effective related improvement strategies. PURPOSE: To explore the risk factors for CABSI after adjusting for confounding factors and to analyze the appropriate protocol for applying retained central venous catheters in hospitalized patients and the impact of CABSI. METHODS: The ethics committee approved this retrospective case-control study. Hospitalized patients who were older than 20 years of age and were currently experiencing their first instance of CABSI were recruited between March 1, 2014 to October 31, 2014 as the case group. In addition, a control group was recruited in a 1:2 ratio from a random sample of patients listed in the medical order system who had received a central venous catheter but did not experience CABSI. Anyone who did not meet the above criteria was excluded. Data collected included basic demographic characteristics, basic catheter information, and the main reason for the catheter being in situ during the 48 hours prior to contracting CABSI or catheter removal. RESULTS: A total of 65 patients with CABSI comprised the case group and 130 patients without CABSI comprised the control group. After controlling for potentially confounding factors using logistic regression analysis, the independent risk factors of CABSI (p < .05) were identified as: staying in the intensive care unit, having a high APACHE II (acute physiology and chronic health evaluation II) score, and having diabetes mellitus. Moreover, while having inappropriate central venous catheter in situ was found to not significantly influence CABSI (OR, 2.41; 95% CI [0.65 8.91]), we identified that about 10.8% of retained central venous catheter applications were unnecessary due to the lack of sufficient indications for use. CONCLUSIONS: We recommend that nursing staffs should remind physicians to evaluate carefully the need to use central venous catheters and should fully implement sterile protocols to protect the health of high-risk patients. In addition, nursing staffs should assess the central venous catheter daily and should remind physicians to remove the catheter as soon as possible in the absence of indications for use. PMID- 30276775 TI - [Using the Facebook Social Networking Website to Improve the Utilization of Weight Loss Programs by Community Obese Adults]. AB - BACKGROUND: In light of the known impacts of obesity on well-being, we regularly work to promote weight loss programs in community settings. However, we found that a gap exists between the need for weight loss and the utilization of healthy weight loss programs among BMI (body mass index) >= 27 kg/m2adults. The low utilization of healthy weight loss programs may lower the overall benefit of these programs. PURPOSE: We reexamined access to health services and developed an accessible weight loss program for BMI >= 27 kg/m2adults that would improve the overall utilization of healthy weight loss programs. RESOLUTION: A telephone survey for obese adults was conducted to explore the reasons that discouraged persons in this group to not use our weight loss programs. The main reasons identified were: program schedules did not fit with respondent's daily schedule, the unsuitable services provided, and the overly long distance to the weight loss class. The social-cognitive-theory-based 1-year weight loss program that was developed provided immediate and accurate information about weight loss, inspiring words, weight management advice, and immediate and convenient consultation services. Moreover, this program established an incentives system on a social networking platform (Facebook) and was marketed under a creative slogan. RESULTS: The developed weight loss program increased not only program utilization (from 54.7% to 78.1%) but also reduced the average weight of obese adult participants by 3.4 kg. CONCLUSIONS: Conclusions: This program adjusted existing weight loss programs and improved the utilization of weight loss programs. These results may be applied elsewhere to increase weight-loss efficacy and to maximize health. PMID- 30276776 TI - [Reducing Blood Culture Contamination Rates in the Emergency Department]. AB - BACKGROUND: Rate of contamination is a well-known indicator of quality of care in the emergency department. Blood-culture results may affect clinical decision making. From January 1, 2015 to December 31, 2015, the contamination rate of blood culture in our emergency department was 5.63%, which exceeded the maximum of 3% suggested by the American Society for Microbiology and the clinical laboratory at our hospital. PURPOSE: Using a quality improvement strategy, this project aimed to (1) identify potential factors contributing to the high blood culture contamination rate and (2) achieve a blood culture contamination rate below 3%. RESOLUTION : The factors that were identified as potentially contributing to the high blood culture contamination rate were: (a) Nursing staff: lack of related education and training and ignorance of related clinical guidelines; (b) The system: inconsistent and non-evidence-based clinical guidelines (e.g., no requirement to use sterile gloves when obtaining blood cultures and changing disinfectants); (c) The patient: older patients, residents of long-term care facility, and patients whose blood culture were in the first set were associated with higher blood culture contamination rates. Our quality improvement strategy included: design a new bedside working plate, develop slogans and posters illustrating the proper blood-drawing procedure, make a video introducing current standard technology, provide continuing education, monitor contamination rates, and provide individual feedback and retraining for those with higher contamination rates. RESULTS: The strategy was implemented from October 1, 2016 to December 31, 2016, during which period the blood culture contamination rate reduced from 5.63% to 1.51%. CONCLUSIONS: Conclusion: Improving equipment, using multiple teaching methods, and providing regular feedback not only significantly reduced the blood culture contamination rate but also enhanced the knowledge and skills of nursing staff in terms of blood culture sampling. We hope that our results are referenced by other nursing departments and used to improve the blood culture contamination rates in other clinical settings. PMID- 30276777 TI - [Applying the Concept of Grief Counseling in Caring for an Elderly Dialysis Patient With Bereavement Due to the Death of Spouse: A Nursing Care Experience]. AB - This article describes a 76-year-old dialysis patient who experienced widowhood. The nursing intervention occurred between April 2nd to June 28th, 2015. Using observation, interviews, medical records and health examinations, the authors assessed the patient's physical, psychological, social, intellectual, and spiritual status. The patient not only presented poor appetite, insomnia, hopelessness, and grief but had also attempted suicide. Thus, three health problems were identified, including dysfunctional grieving, hopelessness, and sleep pattern disturbance. Employing caring, active listening, and empathy, we helped the patient achieve the four tasks of Worden's Mourning: (1) to accept the reality of loss; (2) to work through the pain of grief; (3) to adjust to an environment in which the deceased is missing; and (4) to emotionally relocate the deceased and move on with life. With comprehensive and persistent nursing intervention, the patient got the support from her family members and eventually readapted to life without the deceased and continued to take hemodialysis and found new life motivation. PMID- 30276778 TI - [An Experience Providing Hospice Care to a Terminal Cancer Patient]. AB - This study discusses a case in which corneal-donation care was provided to a 57 year-old patient with terminal salivary gland cancer. Nursing care was provided from June 1 to June 28, 2017. The overall nursing assessment (covering physiological, psychological, social, and spiritual aspects) confirmed that the three main issues faced by the patient were chronic pain, dysfunctional family processes, and spiritual disturbances. Effective pain treatment was applied during the care process in order to stabilize the patient's physical condition. A hospice shared care team then worked together to help the patient mend his relationships with family members, fulfill his wish to donate his cornea, find meaning in his life, affirm his contribution to his family and society, and die a peaceful death. With regard to clinical practice, an explanation of corneal donation should be included in the conventional educational guidelines for hospice care. In addition to referrals to the relevant medical teams, it is recommended that nursing personnel who deal with patients like this participate in organ donation courses and develop positive attitudes and grief counseling skills. These actions will enable them to build up the professionalism, confidence, patience, and organ procurement-related skills required for the provision of care to these patients, which will in turn lead to better-quality palliative care. It is hoped that the nursing experience shared herein provides nursing personnel with a reference for palliative cancer care. PMID- 30276779 TI - [Nursing Experience With Reconstructing Self-Control Using Rational-Emotive Behavior Therapy on a Patient With Schizophrenia and Obsessive-Compulsive Symptoms]. AB - This case report describes a nursing experience caring for a patient with schizophrenia and obsessive-compulsive symptoms. This patient suffered from symptoms of being controlled, obsessive thoughts, and compulsive behaviors. In addition, the patient showed no interest in implementing strategies for dealing with anxiety, no motivation for changing this suffering, and an inability to receive a higher level of rehabilitative job training in daycare. These problems impeded this patient's reintegration into the community. Therefore, the authors employed a five-dimension assessment (physical, emotional, cognitive, social, and spiritual) in order to address the two major nursing problems. The period of nursing care was from October 21, 2016 to January 10, 2017. The two nursing problems addressed included: 1) altered thought processes and 2) ineffective coping. The author provided potentially helpful nursing processes based on the theory of Rational-Emotive Behavior Therapy in order to help the patient cope with symptoms, including being controlled and obsessive-compulsive behaviors. Meanwhile, a relaxation technique was applied to reduce the patient's feelings of discomfort during the nursing processes. As a result, the patient's coping skills to deal with symptoms of being controlled, obsession, and compulsion were improved through refutation of irrational beliefs. In addition to showing rational emotions and appropriate behavior to handle pressures, the patient was also able to apply the relaxation technique to relieve the discomfort from anxiety and pain as needed. This case report suggests that nurses may implement the irrational beliefs refutation training regimen under Rational-Emotive Behavior Therapy for similar cases at the beginning of nursing-patients relationships. Furthermore, providing relaxation techniques in the nursing process may assist patients to deal with stressful life events. The results of this nursing experience are expected to help nursing colleagues apply the above theory and skills with schizophrenia patients with obsessive-compulsive symptoms. PMID- 30276780 TI - Scoping Review of Clinical Outcomes Related to Advanced Training in Wound Care. AB - INTRODUCTION: There are different levels of wound education which exist amongst healthcare providers treating wounds. It is unknown if advanced wound training can lead to improved clinical outcomes. PURPOSE: To review and summarize existing literature focused on the impact of different healthcare professionals with advanced wound care training and the associated effect of clinical outcomes. MATERIALS AND METHODS: The methods used to conduct this scoping review are based on the methodological framework developed by Arksey and O'Malley. An electronic search was performed by independent reviewers using Scopus, CINAHL, PubMed, Google, and EWMA. Consensus decision-making amongst the reviewers resulted in relevant final articles being selected for review. RESULTS: In the literature, there is no universally accepted definition for advanced training in wound care. Seven of the eight selected articles focused on nurses with a specialization in wound healing and their impact on wound healing outcomes. The five main themes identified were wound improvement, cost savings, influence on other nurses, wound recurrence rate, and advanced education. CONCLUSION: A minimum level of advanced training or education would be beneficial to ensure consistency in the provision of advanced wound care by professionals practicing wound care. PMID- 30276781 TI - Linear Wear Rates of a Highly Cross-Linked Polyethylene Hip Liner. AB - INTRODUCTION: To help limit wear, newer polyethylene liners, such as the highly cross-linked polyethylene (HXLPE) liners, have been developed. These newer liners undergo an alternating irradiation process, resulting in a stronger, longer lasting liner. The purpose of this study was to analyze the wear rates of patients who underwent THA and received a newer generation HXLPE acetabular insert. Specifically, we compared: 1) linear vector wear amount and 2) linear vector wear rates in patients as an overall cohort and by gender. We also assessed patient satisfaction outcomes comparing preoperative Harris Hip Scores (HHS) to seven-week, one-year, and three-year HHS scores. MATERIALS AND METHODS: A total of 23 patients who underwent total hip arthroplasty (THA) with direct superior approach by a fellowship-trained orthopaedic surgeon at a private practice institution were analyzed after receiving institutional review board approval. Patients had a minimum two-year follow up, with the mean follow up being four years (range, three to five years). All patients received a 36-mm ceramic femoral head with an HXLPE liner. 2D radiographic polyethylene wear analysis was performed using the Martell Hip Analysis Suite (HAS; University of Chicago, Illinois), which has been previously validated in the literature. Outcomes were assessed using Harris Hip Scores. RESULTS: A five-year linear wear rate of 0.073 mm/year (range, 0 to 0.160 mm/year) and an overall mean linear wear rate of 0.096 mm/year (range, 0 to 0.277 mm/year) were found. No significant differences in wear were seen between genders. Additionally, patients reported significantly better results at seven-weeks (83 points [range, 59 to 100 points]) and one-year (94 points [range, 85 to 100 points]) than preoperative (52 points [range, 34 to 73 points]) HSS scores (p<0.05). No patients underwent revision THA. CONCLUSION: The results from this study highlight the benefits of using an HXLPE polyethylene liner in THA patients and further validates previously reported wear rates of HXLPE liners. After an early "wear in" period during the first year, the wear rates steadily decreased over time. This liner showed excellent early outcomes as no patients underwent revision THA. Furthermore, even as early as seven postoperative weeks, patients reported significantly better HHS scores. Future studies should track the same patient cohort over time to help develop a wear-rate prediction model. PMID- 30276782 TI - A Surgical Case of Inferior Mesenteric Arteriovenous Malformation. AB - The treatment option for inferior mesenteric arteriovenous malformations is under debate because of the number of cases. We, herein, report about a 35-year-old man with congenital inferior mesenteric artery malformation (AVM) presenting with mucous stool and severe abdominal pain. The radical operation, after building the diverting stoma, minimized the extent of the resection. This is the first reported case where surgical management was used to control severe symptoms induced by inferior mesenteric AVM. PMID- 30276783 TI - Can the General Surgeon Use Quilting Sutures to Prevent Seromas Following Abdominal Wall Surgery? AB - A common post-operative complication of many operations is seroma formation, which, while generally considered to be relatively minor, can be problematic for patients and a drain on healthcare resources due to the need for frequent outpatient reviews and repeated aspirations. Several mechanisms have been implicated in the development of seromas, and drains have traditionally been used as a preventative strategy. However, drains are falling out of favour, not least because the evidence to support their use is limited and conflicting. In recent years, the use of quilting sutures, also known as progressive tension sutures, is starting to emerge as a favourable alternative for preventing post-operative seroma formation. Several studies and trials support their use in abdominal wall operations such as abdominoplasties and at abdominal wall donor sites in reconstructive breast operations. General surgeons perform many operations on the abdominal wall, such as ventral hernia repair, that predispose the patient to seroma formation. Can quilting sutures be used in operations on the abdominal wall to prevent seroma formation? This aim of this review was to evaluate the use of quilting sutures as described in several studies to reduce the incidence of post-operative seroma. PMID- 30276784 TI - Pain Reduction with Negative Pressure on Surgical Site Incisions. AB - Postoperative pain management for surgery in the lower extremities has historically been managed mechanically through the use of elevation, ice, compression and drains. Pharmacological management includes the use of nerve blocks and analgesics. Due to the current opioid crisis, new methods are being sought to reduce post-operative pain so that patients are at lower risk for opioid addiction. Postoperative edema control is vital to reduce tension on the incision, since increased incisional tension may cause an increase in pain at the surgical site. Ice, elevation, compression and drains all contribute to edema reduction, and thereby reduce pain and incisional tension. This report introduces a new method for post-operative pain control in lower-extremity surgery. In the author's present clinical experience with 15 patients, the application of negative pressure at the incision site using the PREVENATM Incision Management System (KCI USA, Inc., San Antonio, TX) was associated with a decrease in post operative pain as well as a decrease in the use of narcotics for post-operative pain management. PMID- 30276785 TI - Intracorporeal Anastomosis in Both Elective and Emergency Right Hemicolectomy: Our Experience. AB - PURPOSE: The aim of this study was to examine whether intracorporeal anastomosis (IA) after laparoscopic right hemicolectomy (LRH) is a safe procedure in both emergency and elective settings. METHODS: A retrospective review of all consecutive adult patients (age > 17 years) who underwent LRH from November 2014 to May 2018 at S. Andrea Hospital, La Spezia, was performed. The primary and secondary outcomes were the anastomotic leak rate and the operative time, respectively. Both IA and extracorporeal anastomosis (EA) were performed according to standardized techniques by the same team of experienced surgeons. Our findings were compared to literature data on recent studies comparing IA and EA during LRH. RESULTS: During the observation period, 167 patients underwent RH at our institution: IA was performed in 115. The mean age was 73.5 y. Thirty three RH were performed in an emergency setting: 15 laparotomic procedures, 3 conversions from laparoscopic to open, 6 laparoscopic-assisted with EA, and 9 complete IA. The remaining 134 patients underwent elective RH: IA was performed in 106. The overall anastomotic leak rate in LHR IA was 2.6% (3/115), and no anastomotic leak was reported in the emergency group (0/9). The mean operative time was 180 min. In our experience, the operative time is related to the surgeon's experience and confidence with the technique, and not to the anastomosis technique per se. CONCLUSION: Consistent with the literature data, IA in LRH was associated with better outcomes than EA in both elective and emergency settings. PMID- 30276786 TI - Clinical Results of Direct Anterior Approach THA with Minimal Fluoroscopic Exposure Optimization Techniques. AB - PURPOSE: To determine if low-level intraoperative fluoroscopy usage is associated with increased complications during an initial series for an experienced surgeon transitioning to direct anterior approach (DAA) for total hip arthroplasty (THA). MATERIALS AND METHODS: Subjects who underwent DAA were eligible for analysis. Inclusion criteria included the first 50 subjects who underwent DA hip arthroplasty by a single surgeon (January 2013 to December 2014). Total operating room (OR) time, fluoroscopy absorbed dose, flouoroscopy time, procedure time, and complications were collected and analyzed. Subject demographics were also collected with subjects divided by date of surgery to one of two possible groups. Simple linear regression analysis was performed to determine the relation between case number and both radiation dose and fluoroscopy time. RESULTS: Subjects underwent DAA total hip arthroplasty (n=45). Total OR time ranged from 1.1hrs up to 2.5 hours. Surgeries required an average fluoroscopic time of 7.8 seconds, with improvement over the series of 3.7 seconds. The average radiation dose or fluoroscopy was 2.6 mrem per case. This resulted in a total estimated exposure of 127 mrem over a 23-month period. No patients suffered intraoperative or postoperative fractures or revisions. No significant difference was found for the groups by weight, age, height, and body mass index. Regression analysis yielded a statistically significant (p<0.05) decrease in fluoroscopy time of 0.36 seconds per case over the 45 cases studied. CONCLUSION: An experienced single surgeon's learning curve in DAA THA can be accelerated, with proper training and technique, within a lifetime case experience less than 50 procedures. Surgeons should be aware that with proper techniques and sufficiently-experienced teams, a flattened learning curve is attainable while minimizing fluoroscopy exposure and maintaining clinical outcomes. PMID- 30276787 TI - The Value of Somatostatin Receptor Scintigraphy (SRS) in Patients with NETG1/G2 Pancreatic Neuroendocrine Neoplasms (p-NENs). AB - BACKGROUND: Neuroendocrine neoplasms of the pancreas (p-NEN) are common gastro entero-pancreatic neuroendocrine neoplasms (GEP-NENs). The aim of this retrospective study was to review the of value of Somatostatin Receptor Scintigraphy (SRS) in initial detection of p-NEN, evaluation of tumour extent and as imaging follow-up after radical surgery in patients with confirmed well (NETG1) or moderate (NETG2) differentiated p-NEN based on pathological WHO 2017 classification. MATERIAL AND METHODS: Overall 281 patients with confirmed p-NEN were enrolled. The SRS was performed to evaluation of primary p-NEN, also to assess clinical stage of disease, based on current World Health Organization (WHO) classification and during clinical follow-up. A total of 829 examinations were performed over time in these 281 patients using 99mTc HYNICTOC. Images were acquired between 1 - 3 h after i.v. injection of radiotracer. Initially whole body WB-SPECT and then WB-SPECT/CT, with standard iterative reconstruction were used. RESULTS: There were 159 patients with NETG1 (57%) and 122 subjects with NETG2 (43%). The female to male ratio was 1.1:1. In 68 patients (22%) with NETG1/G2 eight-seven SRS (10%) were performed to confirm initial diagnosis. SRS results were as follow: true positive (TP) = 84 (97%), false negative (FN) = 3 (3%), no true negative (TN) or false positive (FP) results of SRS examination (sensitivity of SRS per patient was 96%). In 198 subjects (66%) SRS was used in evaluation and re-evaluation of the clinical stage, A total of 661 (80%) examinations were carried out in these patients. There were TP=514 (77%), TN=136 (21%), FN=7 (1%) and FP=4 (1%) results. The sensitivity and specificity per patient were: 96% and 95%. The sensitivity and specificity per study: 98% and 97%. In 35 patients (12%) SRS was used as imaging follow-up after radical surgery, there were overall 81 examination (10%) which were performed. There were 76 (91%) TN results of examinations of SRS and in 4 patients we identified recurrence (TP). In total, which consists of initial diagnosis/staging and follow up patients, the sensitivity of SRS was 96% and specificity 97% per patient and per study sensitivity and specificity was 98%. CONCLUSIONS: SRS using 99mTc HYNICTOC acquired in WB-SPECT or WB-SPECT/CT techniques is an excellent imaging modality in detection of primary NETG1/G2 p-NEN. Our study confirms that SRS has high sensitivity and specificity, as a result has tremendous value as an examination method to assess clinical stage of disease and as an imaging follow up after radical treatment.

AB - Angiogenesis, disruption of the retinal barrier, leukocyte-adhesion and oedema are cardinal signs of proliferative retinopathies that are associated with vision loss. Therefore, identifying factors that regulate these vascular dysfunctions is critical to target pathological angiogenesis. Given the conflicting role of bioactive lipids reported in the current literature, the goal of this review is to provide the reader a clear road map of what has been accomplished so far in the field with specific focus on the role of polyunsaturated fatty acids (PUFAs) derived metabolites in proliferative retinopathies. This necessarily entails a description of the different retina cells, blood retina barriers and the role of (PUFAs)-derived metabolites in diabetic retinopathy, retinopathy of prematurity and age-related macular degeneration as the most common types of proliferative retinopathies. PMID- 30276790 TI - Ranging behavior and potential for territoriality in equatorial sakis (Pithecia aequatorialis) in Amazonian Ecuador. AB - OBJECTIVES: Territoriality refers to the consistent defense of an area within the home range (HR) against intrusions of conspecifics. It implies exclusive space use with low degree of overlap among neighboring groups, high site fidelity, specific ranging behavior such as high mobility relative to HR size and frequent visits of territory borders, and monitoring behavior. We examined ranging behavior and use of space to evaluate territoriality in Pithecia aequatorialis in Ecuador. MATERIALS AND METHODS: Between 2005 and 2015, we monitored one main study group continuously and five additional groups for shorter periods (5 months to 2.5 years) at the Tiputini Biodiversity Station, in eastern Ecuador. We scored the location of the study groups at 20 min intervals during, on average, 5 days per month. We estimated saki HRs and core areas (CAs) using the fixed kernel density method (95 and 50%, respectively). RESULTS: The average HR size was 57 ha and the average CA 14 ha. The degree of overlap between HRs of neighboring groups was low (2-9%). For the main study group, the average overlap between annual HRs was 82%. Mean daily path length across groups was 1,151 m; the defensibility index varied between 1.1 and 2.3 (values >1 are suggestive of territoriality), and the fractional monitoring rate varied between 0.06 and 0.15 (values >0.08 are suggestive of territoriality). Groups did not visit their HR borders (100 m inner buffer) more often than would be expected by chance. Travel speed and directness were comparable between the borders and the centers of groups' HRs. DISCUSSION: Our multiyear study suggests that equatorial sakis show low degree of range overlap and high site fidelity and have the potential to be territorial, given their high mobility relative to HR size that allows for frequent border monitoring. Nevertheless, their movement patterns in border areas did not reveal evidence for monitoring behavior.

PMID- 30276791 TI - Contrasting characteristics of daily physical activity in older adults by cancer history. AB - BACKGROUND: Using objectively collected physical activity (PA) data from the Baltimore Longitudinal Study of Aging, the authors tested whether patterns of daily activity and sedentary time differed by cancer survivorship in older adults. METHODS: In total, 659 participants (mean age +/- standard deviation, 71 +/- 10 years; 51% women) who had self-reported information on cancer history were instructed to wear an accelerometer for 7 consecutive days. Accelerometer data were summarized into: 1) PA volume and 2) activity fragmentation (interrupted activity), expressed as both continuous and as dichotomized (low and high) variables. Participants were categorized into 4 groups by cross-classification of dichotomous PA volume and fragmentation. Multiple regression models were used to estimate differences in PA patterns by cancer history. RESULTS: Cancer survivors averaged 0.12 fewer log-transformed activity counts per day (standard error, 0.05; P = .02) than individuals who reported no history of cancer after adjusting for demographics, behavioral factors, and comorbidities. Although fragmentation did not differ by cancer survivorship in the continuous model (P = .13), cancer survivorship was associated with 77% greater odds (odds ratio, 1.77; 95% confidence interval, 1.11-2.82) of having high (vs low) fragmentation and 94% greater odds (odds ratio, 1.94; 95% confidence interval, 1.13-3.33) of having combined low PA/high fragmentation (vs high PA/low fragmentation) relative to those with no cancer history. CONCLUSIONS: The current findings suggest that cancer survivors engage in lower total daily PA and that they perform this activity in a more fragmented manner compared with adults without a history of cancer. These results may reflect the onset and progression of a low-activity phenotype that is more vulnerable to heightened levels of fatigue and functional decline with aging. PMID- 30276793 TI - Impact of change in head and neck position on ultrasound localisation of the cricothyroid membrane: an observational study. AB - The ideal position for performing surgical cricothyroidotomy is with full neck extension. Some authors have recommended marking the cricothyroid membrane before general anaesthesia, typically with the patient's head and neck in a neutral position. The primary aim of this observational study was to determine whether skin marks made over the centre of the cricothyroid membrane with the head and neck in the neutral position moved outside the boundaries of the membrane when the neck was subsequently extended. The secondary aim was to assess changes in the height of the cricothyroid membrane between the neutral and extended positions. Twenty-two volunteers completed the study. With the head and neck in the neutral position, the distance between the upper and lower borders ('height') of the cricothyroid membrane was measured by a radiologist using ultrasound. The skin was marked over the mid-point of the membrane. The subject then maximally extended the neck, and the measurements and marking were repeated. The skin marking over the centre point of the cricothyroid membrane moved by median (IQR [range]) 5 (4-6 [0-10]) mm when the head and neck were moved from a neutral to a fully extended position. The initial skin mark moved to lie outside the boundary of the cricothyroid membrane in 12 of 22 subjects after extending the neck. The height of the cricothyroid membrane increased by 30% with the neck extended. We recommend that marking the skin in preparation for cricothyroidotomy should be performed with the neck extended, not with the head and neck in the neutral position as previously suggested.

PMID- 30276795 TI - Identifying fossil Myrtaceae leaves: the first described fossils of Syzygium from Australia. AB - PREMISE OF THE STUDY: Although leaves of Myrtaceae are easily identified to family level, very few studies have convincingly identified fossil Myrtaceae leaves to living genera. We used a broadly comparative approach with a large data set of extant taxa to confidently assign the mummified remains of myrtaceous leaves from early Miocene sediments at Kiandra (New South Wales, Australia) to a living genus. METHODS: Fossils were identified using a nearest living relative approach, against a database of 232 extant broadleaf rainforest species of Myrtaceae. Leaf cuticles were prepared from 106 species, sourced from herbarium specimens as well as some living individuals, and a further 127 records were assembled from the literature. A set of simple but phylogenetically informative cuticular characters were observed, described, and recorded under both scanning electron microscopy and standard light microscopy. KEY RESULTS: A new fossil species of Syzygium Gaertn. is described from mummified remains found in early Miocene (21.5-21.7 Ma) sediments. The fossil taxon is here named Syzygium christophelii sp. nov., in honor of the late Australian paleobotanist David Christophel. CONCLUSIONS: These fossils represent some of the most confidently described Myrtaceae leaf fossils published to date and are the first and oldest described fossil record of Syzygium from Australia. While several fossil parataxa have been illustrated from New Zealand, and several fossil species of Syzygium have previously been proposed in the literature, many of these fossils lack characters for a confident diagnosis.

PMID- 30276798 TI - Renal cell carcinoma and pathologic nodal disease: Implications for American Joint Committee on Cancer staging. AB - BACKGROUND: Lymph node (LN) metastases are associated with poor outcomes for patients with renal cell carcinoma (RCC). This study compared the survival outcomes of patients with stage III, node-positive disease (pT123 N1 M0 ) and patients with stage III, node-negative disease (pT3 N0 M0 ). METHODS: A database of 4652 patients with RCC of any histological subtype treated with surgery at The University of Texas MD Anderson Cancer Center from 1993 to 2012 was retrospectively assessed. A total of 115 patients with pT123 N1 M0 disease, 274 patients with pT3 N0 M0 disease, and 523 patients with pT123 N0/x M1 disease were included. Overall survival (OS) and cancer-specific survival (CSS) were estimated and compared between each cohort. RESULTS: Median OS and CSS times were significantly better for pT3 N0 M0 patients than pT123 N1 M0 patients (OS, 10.2 vs 2.4 years, P < .0001; CSS, not reached vs 2.8 years, P < .0001). Similar median OS and CSS times were noted for pT123 N1 M0 and pT123 N0/x M1 patients (OS, 2.4 vs 2.4 years; P = .62; CSS, 2.8 vs 2.4 years; P = .10). In a multivariate analysis, tumor grade (hazard ratio [HR] for OS, 2.47; P < .0001; HR for CSS, 2.99; P < .0001) and pathologic LN involvement (HR for OS, 2.44; P < .0001; HR for CSS, 2.85; P < .0001) were associated with worse OS and CSS. CONCLUSIONS: Among RCC patients classified with stage III disease, those with pT123 N1 M0 disease had significantly worse survival than those with pT3 N0 M0 disease. OS and CSS were similar for patients with pT123 N1 M0 disease and patients with pT123 N0/x M1 disease (stage IV). If validated, these findings suggest that RCC patients with nodal disease should be reclassified as having stage IV disease. PMID- 30276799 TI - Improving postpartum screening after diabetes in pregnancy: Results of a pilot study in remote Australia. AB - BACKGROUND: The postpartum period is a critical time to improve health outcomes for Aboriginal women, particularly for those who have chronic conditions. AIMS: To assess enhanced support methods (for women following diabetes in pregnancy (DIP)) to improve completion rates of recommended postpartum health checks. MATERIALS AND METHODS: Fifty-three Aboriginal women in the Northern Territory (NT) were contacted in the postpartum period to encourage medical check-ups. Messages were delivered through phone (call or text messages) or other methods (Facebook or email). The primary outcome was postpartum blood glucose testing (oral glucose tolerance testing (OGTT), random or fasting glucose and HbA1c). RESULTS: Establishing contact with women was difficult. Of 137 messages sent to 52 women, 22 responded (42%). Phone was the most common contact method with successful contact made from 16 of 119 (13%) attempts. Rates of postpartum OGTT completion were higher in the group successfully contacted (32% vs 7%). However, for any postpartum glucose testing (including OGTT and HbA1c) rates were 25 of 42 (60%) and neither success in making contact nor the contact method was associated with higher rates. CONCLUSIONS: The small sample size limits our conclusions; however, results highlight that engaging remote women postpartum is difficult. While rates of postpartum OGTT completion differed according to successful contacts, rates of any postpartum blood glucose testing did not. Further research is needed to explore feasible intervention methods to improve postpartum screening after a pregnancy complicated by diabetes. PMID- 30276800 TI - Parental distress and desire for information regarding long-term implications of pediatric cancer treatment. AB - BACKGROUND: Parents of children with cancer have unmet information needs regarding future limitations resulting from cancer or its treatment. Prior research has demonstrated that, in early care discussions, clinicians focus on the acute effects of therapy rather than long-term limitations, partly due to worries of causing distress. The validity of concerns regarding distress is unknown. In the current study, the authors evaluated parental distress associated with information regarding future limitations, and the extent to which distress is associated with information preferences. METHODS: The authors surveyed 355 parents of children with cancer within 3 months of diagnosis, and the children's physicians at Dana-Farber Cancer Institute/Boston Children's Cancer and Blood Disorders Center and the Children's Hospital of Philadelphia. The primary outcome was parental distress associated with information regarding long-term limitations. RESULTS: Approximately 46% of parents found information regarding future limitations to be extremely or very upsetting. In multivariate analysis, parents were more likely to consider information regarding future limitations distressing if they also found prognostic information upsetting (odds ratio [OR], 5.36; P<.001), struggled to accept their child's illness (OR, 2.57; P<.001), or had depression (OR, 1.79; P=.01). However, approximately 92% of parents considered information regarding potential future limitations to be extremely/very important. Those who found information regarding future limitations distressing were more likely to consider it important (96% vs 89%; P=.03) and to desire a precise understanding of their child's risks (92% vs 80%; P=.001). CONCLUSIONS: Although information regarding future limitations caused by cancer treatment is upsetting to many parents, the majority of them desire this information, and those who are distressed are more likely to value this information. PMID- 30276801 TI - A novel heterozygous variant p.(Trp538Arg) of SYNM is identified by whole-exome sequencing in a Chinese family with dilated cardiomyopathy. AB - Dilated cardiomyopathy (DCM) is a relatively frequent myocardial disease that may lead to heart failure, syncope, and sudden cardiac death. Genetic factors play important roles in the etiology of the disease. To date, at least 50 genes have been identified in patients with DCM, among them, only three mutations have been reported in Synemin (SYNM) gene. In this study, we investigate a Chinese family of three generations with four patients with DCM. Employing whole-exome sequencing (WES) and bioinformatics strategies, a novel heterozygous missense mutation p.(Trp538Arg) of SYNM was identified and cosegregated with the affected family members. The missense mutation locates in the C-terminal domain of SYNM and leads to a substitution of tryptophan by arginine and may cause the structure change of synemin protein. In conclusion, we employed WES to detect the mutations of DCM patients and identified a novel likely pathogenic mutation in SYNM gene. Our study not only expands the spectrum of SYNM mutations, it further confirms that mutations in SYMN may underlie nonfamilial DCM, and offers genetic testing information to additional DCM patients. PMID- 30276803 TI - Characterization of the mating system of a native perennial tetraploid herb, Silene stellata. AB - PREMISE OF THE STUDY: Nursery pollination systems can range from obligate to facultative. In a system where generalists provide substantial pollination service, an important question is whether the cost of seed predation outweighs the benefit provided by the nursery pollinator to cause the plant to evolve toward more generalized pollination. Using a facultative system native to North America, we tested whether nursery pollinator vs. strictly mutualistic generalists affect mating-system parameters of the host plant and explored the implications for long-term coevolution. METHODS: We used paternity analyses with 11 microsatellite markers to characterize the mating system of Silene stellata when pollination service is primarily through the nursery pollinator Hadena ectypa and generalist moths. KEY RESULTS: Our experimental population of S. stellata was predominantly outcrossing (average outcrossing rate t = 0.83), and mating-system parameters were similar between pollinator groups. We detected significant correlations in both selfing and outcrossed paternity at the fruit and maternal family level, corresponding to limited pollen dispersal (mean = 3.9 m). Among individuals, variation in anther-stigma separation was positively associated with outcrossing rate, which suggests the importance of herkogamy in preventing selfing. CONCLUSIONS: Correlated paternity suggests that seeds from the same fruit and/or plants are sired by a limited number of pollen donors, resulting from low pollen dispersal and potential male-male competition. The similar mating-system parameters of the two pollinator groups suggest that selection for higher outcrossing in S. stellata is likely to be through floral design rather than through increased pollinator specialization with H. ectypa.

PMID- 30276802 TI - Nociceptin/Orphanin FQ (N/OFQ) conjugated to ATTO594: a novel fluorescent probe for the N/OFQ (NOP) receptor. AB - BACKGROUND AND PURPOSE: The nociceptin/orphanin FQ (N/OFQ) receptor (NOP) is a member of the opioid receptor family and is involved in a number of physiological responses, pain and immune regulation as examples. In this study, we conjugated a red fluorophore-ATTO594 to the peptide ligand N/OFQ (N/OFQATTO594 ) for the NOP receptor and explored NOP receptor function at high (in recombinant systems) and low (on immune cells) expression. EXPERIMENTAL APPROACH: We assessed N/OFQATTO594 receptor binding, selectivity and functional activity in recombinant (CHO) cell lines. Live cell N/OFQATTO594 binding was measured in (i) HEK cells expressing NOP and NOPGFP receptors, (ii) CHO cells expressing the hNOPGalphaqi5 chimera (to force coupling to measurable Ca2+ responses) and (iii) freshly isolated human polymorphonuclear cells (PMN). KEY RESULTS: N/OFQATTO594 bound to NOP receptor with nM affinity and high selectivity. N/OFQATTO594 activated NOP receptor by reducing cAMP formation and increasing Ca2+ levels in CHOhNOPGalphaqi5 cells. N/OFQATTO594 was also able to visualize NOP receptors at low expression levels on PMN cells. In NOP-GFP-tagged receptors, N/OFQATTO594 was used in a FRET protocol where GFP emission activated ATTO, visualizing ligand-receptor interaction. When the NOPGFP receptor is activated by N/OFQATTO594 , movement of ligand and receptor from the cell surface to the cytosol can be measured. CONCLUSIONS AND IMPLICATIONS: In the absence of validated NOP receptor antibodies and issues surrounding the use of radiolabels (especially in low expression systems), these data indicate the utility of N/OFQATTO594 to study a wide range of N/OFQ-driven cellular responses. PMID- 30276805 TI - SOX-11 regulates LINE-1 retrotransposon activity during neuronal differentiation. AB - Activity of the human long interspersed nuclear elements-1 (LINE-1) retrotransposon occurs mainly in early embryonic development and during hippocampal neurogenesis. SOX-11, a transcription factor relevant to neuronal development, has unknown functions in the control of LINE-1 retrotransposon activity during neuronal differentiation. To study the dependence of LINE-1 activity on SOX-11 during neuronal differentiation, we induced differentiation of human SH-SY5Y neuroblastoma cells and adult adipose mesenchymal stem cells (hASCs) to a neuronal fate and found increased LINE-1 activity. We also show that SOX-11 protein binding to the LINE-1 promoter is higher in differentiating neuroblastoma cells, while knock-down of SOX-11 inhibits the induction of LINE-1 transcription in differentiating conditions. These results suggest that activation of LINE-1 retrotransposition during neuronal differentiation is mediated by SOX-11.

To evaluate predictive validity, 181 infants (median gestational age 30wks [range 22-41wks]; 92 males, 89 females) attending a non-academic outpatient clinic were assessed with SINDA's neurological scale (28 dichotomized items). Atypical neurodevelopmental outcome at 24 months or older corrected age implied a Bayley Mental Developmental Index or Psychomotor Developmental Index lower than 70 or a diagnosis of cerebral palsy (CP). Predictive values were calculated from SINDA (2-12mo corrected age, median 3mo) and typical versus atypical outcome. RESULTS: Intraclass correlation coefficients of intrarater and interrater agreement of the neurological score varied between 0.923 and 0.965. Item difficulty and discrimination were satisfactory. At 24 months or older, 56 children (31%) had an atypical outcome (29 had CP). Atypical neurological scores (below 25th centile, <=21) predicted atypical outcome and CP with sensitivities of 89% and 100%, and specificities of 94% and 81% respectively. INTERPRETATION: SINDA's neurological scale is reliable and in a non-academic outpatient setting has a satisfactory predictive validity for atypical developmental outcome, including CP, at 24 months or older. WHAT THIS PAPER ADDS: The Standardized Infant NeuroDevelopmental Assessment's neurological scale has a good to excellent reliability. The scale has promising predictive validity for cerebral palsy. The scale has promising predictive validity for other types of atypical developmental outcome. PMID- 30276807 TI - Epigenetic Cues Modulating the Generation of Cell-Type Diversity in the Cerebral Cortex. AB - The cerebral cortex is composed of a large variety of distinct cell-types including projection neurons, interneurons and glial cells which emerge from distinct neural stem cell (NSC) lineages. The vast majority of cortical projection neurons and certain classes of glial cells are generated by radial glial progenitor cells (RGPs) in a highly orchestrated manner. Recent studies employing single cell analysis and clonal lineage tracing suggest that NSC and RGP lineage progression are regulated in a profound deterministic manner. In this review we focus on recent advances based mainly on correlative phenotypic data emerging from functional genetic studies in mice. We establish hypotheses to test in future research and outline a conceptual framework how epigenetic cues modulate the generation of cell-type diversity during cortical development.

PMID- 30276808 TI - Identification and pharmacological profile of SPP1, a potent, functionally selective and brain penetrant agonist at muscarinic M1 receptors. AB - BACKGROUND AND PURPOSE: We aimed to identify and develop novel, selective muscarinic M1 receptor agonists as potential therapeutic agents for the symptomatic treatment of Alzheimer's disease. EXPERIMENTAL APPROACH: We developed and utilized a novel M1 receptor occupancy assay to drive a structure activity relationship in a relevant brain region while simultaneously tracking drug levels in plasma and brain to optimize for central penetration. Functional activity was tracked in relevant native in vitro assays allowing translational (rat-human) benchmarking of structure-activity relationship molecules to clinical comparators. KEY RESULTS: Using this paradigm, we identified a series of M1 receptor selective molecules displaying desirable in vitro and in vivo properties and optimized key features, such as central penetration while maintaining selectivity and a partial agonist profile. From these compounds, we selected spiropiperidine 1 (SPP1). In vitro, SPP1 is a potent, partial agonist of cortical and hippocampal M1 receptors with activity conserved across species. SPP1 displays high functional selectivity for M1 receptors over native M2 and M3 receptor anti-targets and over a panel of other targets. Assessment of central target engagement by receptor occupancy reveals SPP1 significantly and dose dependently occupies rodent cortical M1 receptors. CONCLUSIONS AND IMPLICATIONS: We report the discovery of SPP1, a novel, functionally selective, brain penetrant partial orthosteric agonist at M1 receptors, identified by a novel receptor occupancy assay. SPP1 is amenable to in vitro and in vivo study and provides a valuable research tool to further probe the role of M1 receptors in physiology and disease. PMID- 30276809 TI - The Case for Mobility Assessment in Hospitalized Older Adults: American Geriatrics Society White Paper Executive Summary. AB - Mobility can be defined as the ability to move or be moved freely and easily. In older adults, mobility impairments are common and associated with risk for additional loss of function. Mobility loss is particularly common in these individuals during acute illness and hospitalization, and it is associated with poor outcomes, including loss of muscle mass and strength, long hospital stays, falls, declines in activities of daily living, decline in community mobility and social participation, and nursing home placement. Thus, mobility loss can have a large effect on an older adult's health, independence, and quality of life. Nevertheless, despite its importance, loss of mobility is not a widely recognized outcome of hospital care, and few hospitals routinely assess mobility and intervene to improve mobility during hospital stays. The Quality and Performance Measurement Committee of the American Geriatrics Society has developed a white paper supporting greater focus on mobility as an outcome for hospitalized older adults. The executive summary presented here focuses on assessing and preventing mobility loss in older adults in the hospital and summarizes the recommendations from that white paper. The full version of the white paper is available as Text S1. PMID- 30276810 TI - Behavioural interventions to treat drooling in children with neurodisability: a systematic review. AB - AIM: To review the evidence for behavioural interventions to reduce drooling in children with neurodisability. METHOD: A detailed search in eight databases sought studies that: (1) included participants aged 0 to 18 years with neurodisability and drooling; (2) provided behavioural interventions targeting drooling or a drooling-related behaviour; and (3) used experimental designs. Two reviewers extracted data from full-text papers independently. Results were tabulated for comparison. The Risk of Bias assessment in N-of-1 Trials scale for single case experimental designs (SCEDs) and the Cochrane risk of bias assessment tool for randomized controlled trials (RCTs) were applied. RESULTS: Of an initial yield of 763, seven SCEDs and one RCT were included. Behavioural interventions included the use of reinforcement, prompting, self-management, instruction, extinction, overcorrection, and fading. Each assessed body functions or structures' outcomes (drooling frequency and severity); three included activity outcomes (mouth drying, head control, eye contact, and vocalizations) and none assessed participation or quality of life. While each study reported positive effects of intervention, risk of bias was high. INTERPRETATION: Low-level evidence suggests behavioural interventions may be useful for treatment of drooling in children with neurodisability. Well-designed intervention studies are urgently needed to determine effectiveness. WHAT THIS PAPER ADDS: Behavioural interventions used to treat drooling included reinforcement, prompting, self management, extinction, overcorrection, instruction, and fading. Interventions targeted body structures and function-level outcomes and activity-level outcomes. Low-level evidence supports the use of behavioural intervention to treat drooling. PMID- 30276811 TI - Structural and functional neuroimaging in attention-deficit/hyperactivity disorder. AB - Over the last decade, there has been a dramatic increase in the number of neuroimaging studies in attention-deficit/hyperactivity disorder (ADHD). In terms of brain structure, magnetic resonance imaging (MRI), and diffusion tensor imaging studies have evidenced differences in volume, surface-based measures (cortical thickness, surface area, and gyrification), and white matter integrity in different cerebral regions, in children and adults with ADHD compared to population norms. Abnormalities in the basal ganglia, prefrontal structures, and the corpus callosum have been the most consistently reported findings across studies. Hemodynamic (functional MRI, functional near-infrared spectroscopy, positron emission tomography, single-photon emission computed tomography) and magnetoencephalography measurements have also shown differences in neural activity during the execution of neuropsychological tasks and during rest, in widespread regions of the brain. Importantly, multimodal studies combining structural and functional methods have shown an intercorrelation between structural and functional abnormalities in ADHD. Further longitudinal studies are needed to clarify the effects of age and medication on brain structure and function in individuals with ADHD. WHAT THIS PAPER ADDS: In attention deficit/hyperactivity disorder (ADHD), the brain is characterized by abnormal neural network interplay. Structural and functional cerebral abnormalities in ADHD are intercorrelated. Currently there is no neural biomarker that can be used in diagnosis. Longitudinal studies have shed light on the brain correlates of ADHD over the lifespan. The effects of stimulant intake on the brain correlates of ADHD remain unclear. PMID- 30276812 TI - Developmental trajectories of adaptive functioning following early mild traumatic brain injury. AB - Adaptive behavior impairments have been reported in children with severe traumatic brain injury (TBI) but are not typically found following mild TBI. It is possible that mild TBI induces subtle changes in adaptive functioning that are not captured in conventional group comparisons. This study aimed to explore time course changes in adaptive functioning following early mild TBI. Parents of 63 children with mild TBI and 53 children with orthopedic injuries aged between 1.5 and 5 years at the time of injury completed the Adaptive Behavior Assessment System-II at three time points: retrospectively to assess pre-injury functioning, then at 6 and 18 months post-injury. Developmental trajectories of adaptive functioning domains (practical, conceptual, and social) reported by parents were modeled using linear mixed-model analyses. Findings suggest that mild TBI may disrupt the expected developmental progression of children's social adaptive behavior, but does not appear to alter practical and conceptual domains.

PMID- 30276816 TI - Iatrogenic subcutaneous facial emphysema secondary to a Class V dental restoration: a case report. AB - Subcutaneous facial emphysema (SFE) following routine dental operative procedure is an uncommon but potentially life-threatening complication. The present case details a Class V restoration where air was introduced into the fascial tissue planes via the gingival sulcus from the use of an air-driven dental handpiece. Although the SFE is usually self-limiting within 3-10 days, such instances should be regarded as a medical emergency as in severe cases, the air may spread to the neck, mediastinum and thorax to result in cervicofacial emphysema with potential pneumomediastinum and pneumothorax. PMID- 30276815 TI - Brain correlates of stress-induced peripheral vasoconstriction in patients with cardiovascular disease. AB - The influence of acute psychological stress on cardiovascular disease is an emerging public health concern. Identification of brain mechanisms underlying this may aid in the discovery of possible treatments. Acute psychological stress may induce arteriolar vasoconstriction and reduce blood flow to vital organs. We hypothesized that functional changes in brain regions involved with memory and autonomic/emotional regulation are implicated in the vasoconstrictive stress response, including the medial prefrontal cortex (anterior cingulate), insula, and dorsolateral prefrontal cortex. Subjects with a history of coronary artery disease (N = 59) underwent measurement of microvascular vasomotor tone with the EndoPAT device and O-15 positron emission tomography (PET) imaging of the brain during exposure to mental stress and control conditions. The peripheral arterial tonometry (PAT) ratio was calculated as the mean peripheral vasomotor tone during stress divided by the mean tone during rest. Whole brain contrasts were performed between groups above and below the median PAT ratio, and significant contrasts were defined with cutoff p < 0.005. Stress-induced peripheral vasoconstriction (below median PAT ratio) was associated with increased stress activation in insula and parietal cortex, and decreased activation in the medial prefrontal cortex with stress tasks compared to control tasks. These findings demonstrate that stress-induced vasoreactivity is associated with changes in brain responses to stress in areas involved in emotion and autonomic regulation. These findings have important implications on possible treatments for mental stress-induced vascular toxicity. PMID- 30276817 TI - Ocean warming and copper pollution: implications for metabolic compounds of the agarophyte Gelidium floridanum (Gelidiales, Rhodophyta)1. AB - Ocean warming is increasing and scientific predictions suggest a rise of up to 4 degrees C in sea water temperatures. The combination of a polluted and warmer environment may be detrimental for aquatic species, especially for primary producers such as seaweeds. This study investigated the potential for interactive effects of an increased seawater temperature in a copper-rich environment on the photosynthetic pigments and metabolic compounds of the red seaweed Gelidium floridanum. Seaweed samples were cultivated in a factorial design with temperature (24 degrees C and 30 degrees C), copper (0 and 3 MUM), and time (7 and 14 d). The exposure of G. floridanum to copper and 30 degrees C for 7 d resulted in a lower concentration of chlorophyll a, smaller phycobiliprotein rods and lower concentration of soluble sugars. After 14 d of cultivation, a higher concentration of chlorophyll a and soluble sugars could be observed on seaweeds cultivated under 30 degrees C. The accumulation of carotenoids and the release of phenolic compounds indicated specific protective mechanisms against temperature and copper, respectively. Overall, seaweeds grew less when exposed to copper 3 MUM at 30 degrees C. PMID- 30276818 TI - Endophyte traits relevant to stress tolerance, resource use and habitat of origin predict effects on host plants. AB - All terrestrial plants are colonized by foliar endophytic fungi that can affect plant growth and physiology, but the prediction of these effects on the plant host remains a challenge. Here, we examined three paradigms that potentially control how endophytes affect plant hosts: habitat adaptation, evolutionary history and functional traits. We screened 35 plant-endophyte pairings in a microcosm experiment under well-watered and drought conditions with Panicum virgatum as the host. We related the measured plant responses to fungal phylogenetic relatedness, characteristics of fungal habitats across a rainfall gradient and functional traits of the fungi related to stress tolerance and resource use. The functional traits and habitat characteristics of the fungi predicted 26-53% of endophyte-mediated effects on measures of plant growth, physiology and survival. Overall, survival was higher for plants grown with more stress-tolerant fungi, and aboveground biomass was enhanced by fungi from warmer and drier habitats. Plant growth and physiology were also dependent on fungal resource use indicators; however, specific predictors were dependent on water availability. Simple ecological traits of foliar endophytic fungi observed in culture can translate to symbiotic lifestyles. These findings offer new insights and key testable predictions for likely pathways by which endophytes benefit the plant host. PMID- 30276819 TI - An initial investigation of hyperpolarized gas tagging magnetic resonance imaging in evaluating deformable image registration-based lung ventilation. AB - BACKGROUND: Deformable image registration (DIR)-based lung ventilation mapping is attractive due to its simplicity, and also challenging due to its susceptibility to errors and uncertainties. In this study, we explored the use of 3D Hyperpolarized (HP) gas tagging MRI to evaluate DIR-based lung ventilation. METHOD AND MATERIAL: Three healthy volunteers included in this study underwent both 3D HP gas tagging MRI (t-MRI) and 3D proton MRI (p-MRI) using balanced steady-state free precession pulse sequence at end of inhalation and end of exhalation. We first obtained the reference displacement vector fields (DVFs) from the t-MRIs by tracking the motion of each tagging grid between the exhalation and the inhalation phases. Then, we determined DIR-based DVFs from the p-MRIs by registering the images at the two phases with two commercial DIR algorithms. Lung ventilations were calculated from both the reference DVFs and the DIR-based DVFs using the Jacobian method and then compared using cross correlation and mutual information. RESULTS: The DIR-based lung ventilations calculated using p-MRI varied considerably from the reference lung ventilations based on t-MRI among all three subjects. The lung ventilations generated using Velocity AI were preferable for the better spatial homogeneity and accuracy compared to the ones using MIM, with higher average cross correlation (0.328 vs 0.262) and larger average mutual information (0.528 vs 0.323). CONCLUSION: We demonstrated that different DIR algorithms resulted in different lung ventilation maps due to underlining differences in the DVFs. HP gas tagging MRI provides a unique platform for evaluating DIR-based lung ventilation. PMID- 30276820 TI - Recovery in the first six months after hand and upper limb burns: A prospective cohort study. AB - BACKGROUND/AIM: Hands are commonly involved in burn trauma. Occupational therapy in the acute phase aims to reduce the risk of deformities and facilitate return to usual occupations. This study aimed to describe usual occupational therapy care at a major adult burns service, and measure recovery from hand burns in the first six months post-acute hospital discharge. METHOD: To describe usual occupational therapy care, an audit of patient contact statistics over six months was undertaken, and occupational therapy staff were interviewed. To measure recovery, a prospective cohort study recruited adults hospitalised with hand/upper limb burns at the Victorian Adult Burns Service. Recruitment occurred over a four month period. Functional recovery was measured at three time points: discharge, three and six months post-discharge. Instruments included the Quick Disabilities of the Arm, Shoulder and Hand and the Functional Assessment for Burns. RESULTS: Usual care was calculated to be one 30 minute session of daily occupational therapy. Interventions were described using the Template for Intervention Description and Replication. Participants (N = 10) were aged 22-65 years and were treated for burns ranging from 2% to 40% total body surface area. Scores on the Functional Assessment for Burns suggested high functional independence at discharge. Quick Disabilities of the Arm, Shoulder and Hand scores improved significantly at each time point, with most substantial improvement occurring between discharge and three months. Involvement of the first web-space was associated with poorer recovery in the first three months post-discharge (P = 0.04). Six participants (60%) had returned to work at the three month follow-up, and seven (70%) at six months. CONCLUSION: The Quick Disabilities of the Arm, Shoulder and Hand was responsive to recovery in the post discharge period. Further research into upper limb recovery following burns is needed, including exploration of the relationship between recovery and first web space hand burns. PMID- 30276821 TI - Corner's rules as a framework for plant morphology, architecture and functioning issues and steps forward. PMID- 30276822 TI - Anemia in hospitalized patients: an overlooked risk in medical care. AB - BACKGROUND: This study investigated the association between nadir anemia and mortality and length of stay (LOS) in a general population of hospitalized patients. STUDY DESIGN AND METHODS: A retrospective cohort study of tertiary hospital admissions in Western Australia between July 2010 and June 2015. Outcome measures were in-hospital mortality and LOS. RESULTS: Of 80,765 inpatients, 45,675 (56.55%) had anemia during admission. Mild and moderate/severe anemia were independently associated with increased in-hospital mortality (odds ratio [OR] 1.5, 95% confidence interval [CI] 1.36-1.86, p = 0.001; OR 2.77, 95% CI 2.32 3.30, p < 0.001, respectively). Anemia was also associated with increased LOS, demonstrating a larger effect in emergency (mild anemia-incident rate ratio [IRR] 1.52, 95% CI 1.48-1.56, p < 0.001; moderate/severe anemia-IRR 2.18, 95% CI 2.11 2.26, p < 0.001) compared to elective admissions (mild anemia-IRR 1.30, 95% CI 1.21-1.41, p < 0.001; moderate/severe anemia-IRR 1.69, 95% CI 1.55-1.83, p < 0.001). LOS was longer in patients who developed anemia during admission compared to those who had anemia on admission (IRR 1.13, 95% CI 1.10-1.17, p < 0.001). Red cell transfusion was independently associated with 2.23 times higher odds of in hospital mortality (95% CI 1.89-2.64, p < 0.001) and 1.31 times longer LOS (95% CI 1.25-1.37, p < 0.001). CONCLUSION: More than one-third of patients not anemic on admission developed anemia during admission. Even mild anemia is independently associated with increased mortality and LOS; however, transfusion to treat anemia is an independent and additive risk factor. PMID- 30276823 TI - Involvement of neutrophils in Chagas disease pathology. AB - Chagas disease (CD) is a public health problem in Latin America. The acute phase presents nonspecific symptoms and most patients recover from acute parasitemia and undergo a prolonged asymptomatic phase. Several years later, about 30% of infected individuals develop chronic cardiopathy with progressive cardiomegaly, arrhythmia, thromboembolic events and heart failure. These symptoms suggest a persistent association with the presence of inflammatory infiltrate and tissue, and cellular destruction in the heart muscle. Nevertheless, few research studies have attempted to understand the role of inflammatory cells, such as neutrophils, in establishing the pathology and progression of CD. Only recently have some studies been performed with this intention. Despite this effort, the role of neutrophils in CD is still considered controversial. This review discusses the morphological and functional characteristics of neutrophils that describes their participation in the establishment and progression of Trypanosoma cruzi infection, through the development of its effector functions, such as release of lithic components, production of oxidative agents and release of inflammatory mediators capable of modulating the host immune response. PMID- 30276824 TI - Gonyaulax whaseongensis sp. nov. (Gonyaulacales, Dinophyceae), a new phototrophic species from Korean coastal waters. AB - The planktonic phototrophic dinoflagellate Gonyaulax whaseongensis sp. nov., isolated from coastal waters of western Korea, was described from living and fixed cells under light and scanning electron microscopy, and its rDNA was sequenced. Gonyaulax whaseongensis had a plate formula of 2pr, 4', 6'', 6c, 6''', 1p, and 1'''' with S-type ventral organization like the other species in the genus. However, this dinoflagellate had a narrow cingulum (ca. 2.6 MUm), small displacement of the cingulum, slight overhang and steep angle between the ends of the cingulum, quadrangular sixth precingular plate, reticulated cell surface without longitudinal lines or ridges, and two unequal antapical spines, together which distinguish this from all other reported Gonyaulax species. In addition, the SSU and LSU rDNA sequences were 8%-12% and 11%-24%, respectively, different from those of Gonyaulax polygramma, Gonyaulax spinifera, Gonyaulax fragilis, Gonyaulax membranacea, and Gonyaulax digitale, the putatively closest related species in the phylogenetic analysis. PMID- 30276825 TI - CAD1 and CCR2 protein complex formation in monolignol biosynthesis in Populus trichocarpa. AB - Lignin is the major phenolic polymer in plant secondary cell walls and is polymerized from monomeric subunits, the monolignols. Eleven enzyme families are implicated in monolignol biosynthesis. Here, we studied the functions of members of the cinnamyl alcohol dehydrogenase (CAD) and cinnamoyl-CoA reductase (CCR) families in wood formation in Populus trichocarpa, including the regulatory effects of their transcripts and protein activities on monolignol biosynthesis. Enzyme activity assays from stem-differentiating xylem (SDX) proteins showed that RNAi suppression of PtrCAD1 in P. trichocarpa transgenics caused a reduction in SDX CCR activity. RNAi suppression of PtrCCR2, the only CCR member highly expressed in SDX, caused a reciprocal reduction in SDX protein CAD activities. The enzyme assays of mixed and coexpressed recombinant proteins supported physical interactions between PtrCAD1 and PtrCCR2. Biomolecular fluorescence complementation and pull-down/co-immunoprecipitation experiments supported a hypothesis of PtrCAD1/PtrCCR2 heterodimer formation. These results provide evidence for the formation of PtrCAD1/PtrCCR2 protein complexes in monolignol biosynthesis in planta. PMID- 30276827 TI - Re-imagining occupational wellbeing: Development of an evidence-based framework. AB - BACKGROUND/AIM: Occupational therapists concern themselves with understanding engagement in everyday activity as a mode of facilitating wellbeing. However, there appears to be little consensus within the literature as to how engagement in meaningful activities contributes to wellbeing. Currently, there are no published evidence-based frameworks for wellbeing to support occupational therapy practitioners to address wellbeing with clients. The purpose of the study was to establish an evidence-based contemporary framework, domains and descriptive statements defining occupational wellbeing. METHODS: A multiphase, exploratory sequential mixed methods design, using both qualitative and quantitative approaches was used. Two phases were identified for data collection. The first phase involved exploration of the domains of occupational wellbeing, through conducting a literature review and two focus groups. The Delphi technique was employed in the second phase to refine and corroborate the domains of occupational wellbeing with an expert panel. RESULTS: Six new domains of occupational wellbeing were generated in the first phase of the study, namely: Competence, autonomy, contentment and pleasure, identity, hope and belonging. In the second phase, five out of the six domains reached a consensus level of 70% or more. Hope was the only domain not to reach consensus. CONCLUSION: The framework for occupational wellbeing produced by this study was created using evidence based, replicable methodology and garnered support from a highly regarded expert key informant group of occupational therapy and occupational science academics. Further exploration to determine whether there is widespread support and applicability for these domains with normative and vulnerable population groups is required. PMID- 30276826 TI - Bronchiolitis needs a revisit: Distinguishing between virus entities and their treatments. AB - Current data indicate that the "bronchiolitis" diagnosis comprises more than one condition. Clinically, pathophysiologically, and even genetically three main clusters of patients can be identified among children suffering from severe bronchiolitis (or first wheezing episode): (a) respiratory syncytial virus (RSV) induced bronchiolitis, characterized by young age of the patient, mechanical obstruction of the airways due to mucus and cell debris, and increased risk of recurrent wheezing. For this illness, an effective prophylactic RSV-specific monoclonal antibody is available; (b) rhinovirus-induced wheezing, associated with atopic predisposition of the patient and high risk of subsequent asthma development, which may, however, be reversed with systemic corticosteroids in those with severe illness; and (c) wheeze due to other viruses, characteristically likely to be less frequent and severe. Clinically, it is important to distinguish between these partially overlapping patient groups as they are likely to respond to different treatments. It appears that the first episode of severe bronchiolitis in under 2-year-old children is a critical event and an important opportunity for designing secondary prevention strategies for asthma. As data have shown bronchiolitis cannot simply be diagnosed using a certain cutoff age, but instead, as we suggest, using the viral etiology as the differentiating factor. PMID- 30276828 TI - Bursting strength of surgeon's and self-locking knots for closure of ventral midline celiotomy in horses. AB - OBJECTIVE: To compare the bursting strength and failure mode of ventral midline celiotomy closed with a simple continuous suture pattern with 1 of 2 knot combinations, a novel self-locking knot combination of a forwarder start with an Aberdeen end knot (F-A) and a traditional combination of a surgeon's start with a surgeon's end knot (S-S). STUDY DESIGN: Ex vivo experimental. SAMPLE POPULATION: Equine cadavers (n = 14). METHODS: A 20-cm ventral midline celiotomy was created in 14 equine cadavers. Horses were assigned to celiotomy closure with an F-A or S S knot combination. Prior to closure, a 200-L inflatable bladder was placed in the abdomen and then insufflated until failure of the celiotomy closure. The horses' signalment, weight, breed, and age, as well as knot combination type, mode of failure, closure time, and bursting strength (mm Hg) were recorded. RESULTS: The median bursting strength was significantly greater when incisions were closed with the F-A knot combination (388 mm Hg) compared with the S-S knot combination (290 mm Hg) (P = .035). Most incisions failed along the fascia when closed with F-A combinations and at the knot when closed with S-S combinations. CONCLUSION: The bursting strength of ventral midline incisions in equine cadavers was increased by an average of 25% when closed with the self-locking F-A knot combination. CLINICAL SIGNIFICANCE: Closing ventral midline celiotomies with an F A knot combination may provide a more secure closure than the traditional S-S knot combination. Additional in vivo investigation is required prior to recommending this closure in clinical cases. PMID- 30276829 TI - Response to AASLD editorial/message from the president.

PMID- 30276830 TI - Pharmacokinetic studies of soyalkaloid A from Portulaca oleracea L. using ultra high-performance liquid chromatography electrospray ionization quadrupole-time of flight mass spectrometry and its antioxidant activity. AB - Soyalkaloid A was isolated from Portulaca oleracea L. for the first time in our laboratory and then a rapid and sensitive ultra-high-performance liquid chromatography electrospray ionization quadrupole-time of flight mass spectrometry (UHPLC-ESI-Q-TOF/MS) method with hesperidin as internal standard (IS) was developed and validated to investigate the pharmacokinetics of soyalkaloid A in rats after oral and intravenous administrations. The analysis was achieved on an Agilent Zorbax Eclipse Plus C18 Column (2.1 * 50 mm, 1.8 MUm) by elution with acetonitrile and water (containing 0.1% formic acid), at a flow rate of 0.3 mL/min. The MS analysis was performed in the positive ion mode with monitored ion m/z 227.0814 [M + H]+ and 611.1971 [M + H]+ for soyalkaloid A and IS, respectively. The linear range was established over the concentration range 7.5-6000 ng/mL (r = 0.9951). The intra- and inter-assay accuracy and precision were between -4.86-4.49 and 1.93-9.66, respectively. The lower limits of detection and quantitation observed were 2.1 and 7.4 ng/mL, respectively. The rapid, sensitive and specific UHPLC-ESI-Q-TOF/MS method was successfully applied to a pharmacokinetic study of soyalkaloid A. Moreover, its antioxidant was studied via a 1,1-diphenyl-2-picryl-hydrazyl radical scavenging assay, the IC50 value being 20.73 +/- 0.51 MUM. PMID- 30276831 TI - LncRNAnet: a comprehensive Sus scrofa lncRNA database. AB - Long noncoding RNAs (lncRNAs) constitute a large class of functional non-coding RNAs that play important roles in many biological processes. Thousands of lncRNAs have been identified in mammals. Pig is an important farm animal and biomedical model. It is essential to create a Sus scrofa lncRNA database to enable further study of the function and evolution of lncRNAs. In this study, we built a systematic S. scrofa lncRNA database named lncRNAnet that contains 53 468 S. scrofa lncRNAs with their sequence characteristics, genomic locations, conservation, overlapping SNPs and QTLs, and transcript abundance across nine tissues in pigs. We also integrated 212 922 human and mouse lncRNAs sequences into lncRNAnet. This database will provide for a systematic S. scrofa lncRNA classification and help investigators browse, search for and analyze lncRNAs as well as do blast searches among human, mouse and pig lncRNAs. Thus, lncRNAnet should improve the understanding of the biological functions of lncRNA. The database is freely accessible at http://lnc.rnanet.org/. PMID- 30276833 TI - Study on bioequivalence of beraprost in healthy volunteers by liquid chromatography with tandem mass spectrometry. AB - Beraprost sodium is an oral prostacyclin analog that was first approved in 1992 (Japan) for the treatment of peripheral vascular disorders. It is administered orally as a tablet available in strength 20 MUg. In this paper, we described a liquid chromatography tandem mass spectrometry method that was developed for the quantification of beraprost in human plasma with high sensitivity at picogram per milliliter concentration. The method had been validated in terms of selectivity, sensitivity, accuracy and precision, matrix effect, linearity, recovery and carry over according to the Guideline on Bioanalytical Validation from the European Medicines Agency. The standard calibration curve for beraprost was 9.5-1419 pg/mL. This method has been applied successfully to a bioequivalence study with 60 MUg of beraprost (three tablets) in 29 healthy volunteers. The results showed that the two formulations of beraprost are bioequivalent. PMID- 30276832 TI - Meta-Analysis of Genetic Influences on Initial Alcohol Sensitivity. AB - BACKGROUND: Previous studies indicate that low initial sensitivity to alcohol may be a risk factor for later alcohol misuse. Evidence suggests that initial sensitivity is influenced by genetic factors, but few molecular genetic studies have been reported. METHODS: We conducted a meta-analysis of 2 population-based genome-wide association studies of the Self-Rating of the Effects of Alcohol scale. Our final sample consisted of 7,339 individuals (82.3% of European descent; 59.2% female) who reported having used alcohol at least 5 times. In addition, we estimated single nucleotide polymorphism (SNP)-based heritability and conducted a series of secondary aggregate genetic analyses. RESULTS: No individual locus reached genome-wide significance. Gene and set based analyses, both overall and using tissue-specific expression data, yielded largely null results, and genes previously implicated in alcohol problems and consumption were overall not associated with initial sensitivity. Only 1 gene set, related to hormone signaling and including core clock genes, survived correction for multiple testing. A meta-analysis of SNP-based heritability resulted in a modest estimate of CONCLUSIONS: Findings yielded only modest support for a genetic component underlying initial alcohol sensitivity. Results suggest that its biological underpinnings may diverge somewhat from that of other alcohol outcomes and may be related to core clock genes or other aspects of hormone signaling. Larger samples, ideally of prospectively assessed samples, are likely necessary to improve gene identification efforts and confirm the current findings. PMID- 30276834 TI - Amniotic fluid cell-free DNA in preterm prelabor rupture of membranes. AB - INTRODUCTION: We evaluated the levels of cell-free nuclear DNA (nDNA) and cell free mitochondrial DNA (mtDNA) in the amniotic fluid supernatant from pregnancies complicated by preterm prelabor rupture of membranes (PPROM) based on evidence of microbial invasion of the amniotic cavity (MIAC) and/or intra-amniotic inflammation (IAI). MATERIAL AND METHODS: A total of 155 women with PPROM were included in this study. Amniotic fluid samples were obtained by transabdominal amniocentesis. The levels of cell-free nDNA and mtDNA in the amniotic fluid supernatant were assessed and quantified by real-time polymerase chain reaction. RESULTS: The levels of cell-free nDNA and mtDNA were higher in women with MIAC and IAI than in women without these conditions (nDNA: with MIAC: median 3.9 * 104 genome equivalent [GE]/mL vs without MIAC: median 1.2 * 104 GE/mL, with IAI: median: 5.3 * 104 GE/mL vs without IAI: median 1.2 * 104 GE/mL; mtDNA: with MIAC: median 9.2 * 105 GE/mL vs without MIAC: median 2.5 * 105 GE/mL, with IAI: median 1.1 * 106 GE/mL vs without IAI: median 2.5 * 105 ; all P values <= 0.01). Women with the microbial-associated IAI showed the highest levels of cell-free nDNA and mtDNA. CONCLUSIONS: Cell-free nDNA and mtDNA are constituents of the amniotic fluid supernatant from PPROM pregnancies. Both cell-free nDNA and mtDNA are involved in the intra-amniotic inflammatory response in women with PPROM. PMID- 30276835 TI - Antiviral compound screening, peptide designing, and protein network construction of influenza a virus (strain a/Puerto Rico/8/1934 H1N1). AB - Hit, Lead & Candidate Discovery Plant-based antiviral therapy is the current need for holistic health care management, which can be achieved through screening of phytochemicals and designing of antiviral peptides. There exist certain host's factors which are directly involved for rapid viral replication causing worldwide pandemic. A total of 177 phytochemicals from Ocimum sanctum (L.), Tinospora cordifolia (Thunb.) Miers, Cinnamomum camphora (L.) J. Presl., Allium sativum (L.), Curcuma longa (L.), and Aloe vera (L.) Burm. f. were evaluated for their affinity to all viral proteins of H1N1. Applying drug filters and keeping the threshold of such filters relative to the standards, 82 compounds were found suitable for further analysis. Consensus scoring system was used for screening top ligands from 82 compounds, which screened the top 12 compounds. Highly conserved regions (>80%) which were hydrophilic, flexible, antigenic, and also charged were screened out as potent antiviral peptides. The viral proteins were taken as the targets for the modeled peptides for protein-protein docking. Further, host-pathogen interacting network was constructed to unveil host factors involved in viral replication, from which unique protein clusters representing their involvement in viral reproduction were selected through mapping with pathway databases. Twelve compounds and five peptides were found to be highly effective against all the proteins of H1N1. Based on the uniqueness, 13 clusters of proteins were obtained which are engaged in cellular process, namely, viral reproduction, fructose-6-phosphate metabolism, nitrogen compound metabolism, biosynthesis, cellular process, oligodendrocyte development, localization, multiorganism process, primary metabolism, response to unfolded protein, metabolism, and response to protein and catabolism. PMID- 30276836 TI - A frameshift variant in the EDA gene in Dachshunds with X-linked hypohidrotic ectodermal dysplasia. AB - X-linked hypohidrotic ectodermal dysplasia (XLHED) is a genetic disease characterized by hypoplasia or absence of hair, teeth and sweat glands. The EDA gene, located on the X chromosome, encodes the type II transmembrane protein ectodysplasin A. Variants in the EDA gene can lead to XLHED in humans, mice, cattle and dogs. In the present study, we investigated a litter of Dachshund puppies, of which four male puppies showed clinical signs of XLHED. We performed a candidate gene analysis in one affected puppy and several non-affected relatives. This analysis revealed a single base-pair deletion in the coding sequence of the EDA gene in the affected puppy (NM_001014770.2:c.842delT). The deletion is predicted to cause a frameshift, NP_001014770.1:p.(Leu281HisfsTer22), leading to a premature stop codon which truncates more than one quarter of the EDA protein. Sanger sequencing results confirmed that this variant was inherited from the dam. Based on knowledge about the functional impact of EDA variants in dogs and other species, c.842delT is a convincing candidate causative variant for the observed XLHED in the male puppies. PMID- 30276837 TI - Antiallodynic interaction and motor performance of the pregabalin/thioctic acid and pregabalin/alpha-tocopherol combinations in neonatal streptozotocin-induced diabetic rats. AB - Painful peripheral neuropathy can be associated with nerve damage caused by diabetes mellitus. Although pregabalin is the first-line therapy for peripheral neuropathy, it shows substantial discontinuation rates, mainly because of nervous system side effects as motor incoordination. Multimodal therapy may improve the motor side effect profile of pregabalin. The aim of this study was to evaluate the interaction of pregabalin + thioctic acid or pregabalin + alpha-tocopherol on allodynia and motor performance in neonatal streptozotocin-induced diabetic rats. Efficacy of drugs separately or in combination was tested by tactile allodynia using von Frey filaments. Isobolographic and interaction index analysis were used to determine the antiallodynic interaction between pregabalin and either thioctic acid or alpha-tocopherol. Motor performance was measured using a rotarod test. Pregabalin, thioctic acid, and alpha-tocopherol reduced, in a dose-dependent fashion, tactile allodynia. Pregabalin + thioctic acid and pregabalin + alpha tocopherol combinations also dose-dependently reduced allodynic behavior in diabetic rats. Isobolographic analysis revealed an additive interaction for both combinations. Consistently, the interaction indices confirmed the additive effect between pregabalin + thioctic acid and pregabalin + alpha-tocopherol. In addition, the administration of either combination improved motor incoordination induced by pregabalin. Data suggests that thioctic acid or alpha-tocopherol could positively impact the therapeutic profile of pregabalin, because they might be useful for reducing motor incoordination associated to pregabalin in patients with peripheral neuropathy. PMID- 30276838 TI - Curcumin potentiates the fungicidal effect of dodecanol by inhibiting drug efflux in wild-type budding yeast. AB - Drug resistance commonly occurs when treating immunocompromised patients who have fungal infections. Curcumin, is a compound isolated from Curcuma longa, has been reported to inhibit drug efflux in several human cell lines and nonpathogenic budding yeast Saccharomyces cerevisiae cells that overexpresses the ATP-binding cassette (ABC) transporters S. cerevisiae Pdr5p and pathogenic Candida albicans Cdr1p and Cdr2p. The aim of this study was to examine the effects of curcumin on multidrug resistance in a wild-type strain of the budding yeast with an intrinsic expression system of multidrug efflux-related genes. The antifungal activity of dodecanol alone was temporary against S. cerevisiae; however, restoration of cell viability was completely inhibited when the cells were co-treated with dodecanol and curcumin. Furthermore, restriction of rhodamine 6G (R6G) efflux from the cells and intracellular accumulation of R6G were observed with curcumin treatment. Reverse transcription-polymerase chain reaction analysis revealed that curcumin reduced the dodecanol-induced overexpression of the ABC transporter related genes PDR1, PDR3 and PDR5 to their control levels in untreated cells. Curcumin can directly restrict the glucose-induced drug efflux and inhibits the expression of the ABC transporter gene PDR5, and can thereby inhibit the efflux of dodecanol from S. cerevisiae cells. Curcumin is effective in potentiating the efficacy of antifungal drugs via its effects on ABC transporters. SIGNIFICANCE AND IMPACT OF THE STUDY: Drug resistance is common in immunocompromised patients with fungal infections. Curcumin, isolated from Curcuma longa, inhibits drug efflux in nonpathogenic budding yeast Saccharomyces cerevisiae cells overexpressing ABC transporters S. cerevisiae Pdr5p and pathogenic Candida albicans Cdr1p and Cdr2p. We examined the effects of curcumin on multidrug resistance in a wild-type strain of the budding yeast with an intrinsic expression system of multidrug efflux-related genes. Curcumin directly inhibited drug efflux and also suppressed the PDR5 expression, thereby enhancing the antifungal effects. Thus, curcumin potentially promotes the efficacy of antifungals via its effects on ABC transporters in wild-type fungal strains. PMID- 30276839 TI - Matched or unmatched analyses with propensity-score-matched data? AB - Propensity-score matching has been used widely in observational studies to balance confounders across treatment groups. However, whether matched-pairs analyses should be used as a primary approach is still in debate. We compared the statistical power and type 1 error rate for four commonly used methods of analyzing propensity-score-matched samples with continuous outcomes: (1) an unadjusted mixed-effects model, (2) an unadjusted generalized estimating method, (3) simple linear regression, and (4) multiple linear regression. Multiple linear regression had the highest statistical power among the four competing methods. We also found that the degree of intraclass correlation within matched pairs depends on the dissimilarity between the coefficient vectors of confounders in the outcome and treatment models. Multiple linear regression is superior to the unadjusted matched-pairs analyses for propensity-score-matched data. PMID- 30276840 TI - Dopamine D2 receptors in the basolateral amygdala modulate erectile function in a rat model of nonorganic erectile dysfunction. AB - Nonorganic erectile dysfunction is a problem with unknown central mechanisms. Changes in brain activity in the amygdala have been observed in human patients. This study aimed to investigate the dopamine system in the basolateral amygdala of male rats with nonorganic erectile dysfunction. We applied chronic mild stress to induce nonorganic erectile dysfunction. After exposure to chronic mild stress, the sucrose consumption test, sexual behaviour test and apomorphine test were used to select depression-like rats with erectile dysfunction as nonorganic erectile dysfunction model rats. The sexual behaviour of these rats after central infusion of a dopamine D1/D2 receptor agonist/antagonist was observed. The expression levels of dopamine D1/D2 receptors and tyrosine hydroxylase in the basolateral amygdala were also measured. The result of the sucrose consumption test, sexual behaviour test and apomorphine test indicated a successful nonorganic erectile dysfunction model. Central infusion of a dopamine D2 receptor agonist increased intromission ratio in model rats. Lower expression levels of tyrosine hydroxylase and the dopamine D2 receptor in the basolateral amygdala were observed in rats with nonorganic erectile dysfunction. These results suggest that impairment of the dopamine D2 receptor pathway in the basolateral amygdala may contribute to the development of nonorganic erectile dysfunction. PMID- 30276841 TI - Schistosomiasis (bilharziasis) and male infertility. AB - Schistosomiasis (bilharziasis) is an endemic parasitic disease of a major source of morbidity and mortality for developing countries. It is caused by different species of blood flukes (trematode worms) of the genus Schistosoma, the most important of which are S. haematobium which infests the genitourinary tract and S. mansoni and S. japonicum which infest the gastrointestinal tract. The incidence of schistosome-induced male infertility is not known and probably underestimated being overshadowed by the more severe and often fatal urinary and gastrointestinal complications. Several causes may contribute to schistosomiasis induced male infertility, such as hormonal imbalance, testicular tissue damage and genital ductal system obstruction, in addition to decreased libido and erectile dysfunction due to associated hormonal imbalance and prostatic infestation. Demonstration of the schistosome ova in seminal plasma or testicular tissue confirms the diagnosis. Treatment of schistosomiasis-induced male infertility depends on clinical evaluation and includes, besides anthelmintic treatment, hormonal replacement and assisted reproduction (IVF/ICSI) in cases of severe oligozoospermia and or obstructive and nonobstructive azoospermia. PMID- 30276842 TI - Access to a school health nurse and adolescent health needs in the universal school health service in Finland. AB - Universal school health services are expected to offer similar, needs-based services to all students across schools, service providers and students' socio economic statuses and health needs. This study investigates access to school health nurses in Finland. The objectives were to study the differences in access to school health nurse between service providers, schools, students' characteristics and school health nurse resources. Access was examined through a nationwide School Health Promotion study, which is a self-reporting, voluntary and anonymous survey for 8th and 9th graders (15 to 16-year old, N = 71865). The ethical committee of the National Institute for Health and Welfare has approved procedure for the School Health Promotion study. Data on school health nurse resources and service providers were obtained from the national database (534 schools; 144 service providers). Multilevel logistic regression was used. Of the pupils, 15% of girls and 11% of boys reported difficult access to a school health nurse. The number of adolescents who reported difficult access ranged between service providers (0%-41%) and schools (0%-75%). Students with lower socio economic background, poorer well-being at school, lack of support for studying and greater health needs reported difficult access more often. School health nurse resources were associated with difficult access only among boys, when resources were under the national recommendations. These findings raise concern about equality and unmet health needs in school health services. PMID- 30276843 TI - Exposure to Plasmodium vivax is associated with the increased expression of exhaustion markers on gammadelta T lymphocytes. AB - Gamma delta (gammadelta) T cells exhibit potent anti-Plasmodium activity but are also implicated in the immunopathology of malaria. It is currently poorly understood how gammadelta T cells are affected in human suffering from Plasmodium vivax infection or in symptomless individuals living in an endemic region. We examined both the percentages and expression of markers associated with immune exhaustion in gammadelta T cells in individuals living in a P. vivax endemic region by flow cytometry. The percentage of gammadelta T cells in the blood was significantly higher both in acute P. vivax-positive patients and in individuals from an endemic region in comparison with control uninfected adults. The frequency of the expression of the exhaustion markers-Tim-3, Lag-3, CTLA-4 and PD 1 was higher in gammadelta and total T cells from P. vivax-infected patients than in those populations from control uninfected adults. Individuals from a P. vivax endemic region showed elevated percentages of Tim-3-, Lag-3- and CTLA-4-positive gammadelta T cells and an increased percentage of Tim-3-positive total T cells. The phenotypic exhaustion of these cells might be a protective mechanism preventing the immunopathology associated with activated T cells and may provide a rationale for targeted manipulation of this process in diseases such as malaria. PMID- 30276844 TI - Genome-wide association study and heritability estimate for ectopic ureters in Entlebucher mountain dogs. AB - An ectopic ureter is a congenital anomaly which may lead to urinary incontinence and without a surgical intervention even to end-stage kidney disease. A genetic component contributes to the development of this anomaly in Entlebucher mountain dogs (EMD); however, its nature remains unclear. Using the Illumina CanineHD bead chip, a case-control genome-wide association study was performed to identify SNPs associated with the trait. Six loci on canine chromosomes 3, 17, 27 and 30 were identified with 16 significantly associated SNPs. There was no single outstanding SNP associated with the phenotype, and the association signals were not close to known genes involved in human congenital anomalies of the kidney or lower urinary tract. Additional research will be necessary to elucidate the potential role of the associated genes in the development of ectopic ureters in the EMD breed. PMID- 30276845 TI - Difference in the seminal plasma protein expression in unexplained infertile men with successful and unsuccessful in vitro fertilisation outcome. AB - Unexplained male infertility (UMI) is a condition in which routine semen analysis fails to detect subcellular sperm dysfunctions. In the present research, a comparative proteomics study of seminal plasma (SP) was conducted in men with unexplained infertility whose female partners had undergone in vitro fertilisation (IVF) treatment to find differences in the SP protein profile. Five UMI men with successful and eight with unsuccessful IVF outcome enrolled in this study. Two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) technique was used for protein separation. The differentially expressed proteins were identified using mass spectrometry. Results indicated that at least two different protein spots, including clusterin and epididymal secretory protein E1, were over expressed (1.5- and 2-fold change, respectively, p < 0.05) while prostate specific antigen was downregulated (0.3-fold change, p < 0.05) in the successful group as compared with the unsuccessful group. Considering the role of all three identified proteins in the sperm quality, the results of the present study introduced these proteins as new candidate biomarkers for success of IVF in UMI couples. PMID- 30276846 TI - Effect of chrysin on methotrexate-induced testicular damage in rats. AB - This study was conducted on 28 male Wistar albino rats to determine the effects of chrysin on methotrexate-induced damage to testicular tissue. Rats were grouped into four groups of seven rats reach: Group 1 (n = 7) was the control group to which no drugs were administered; this group was only provided with food and water. Group 2 (n = 7) was administered 20 mg/kg of methotrexate once intraperitoneally. Group 3 (n = 7) was administered 50 mg/kg of chrysin for 7 days orally. Group 4 (n = 7) was administered 20 mg/kg of methotrexate once intraperitoneally, followed by oral administration of 50 mg/kg of chrysin for 7 days. At the end of the experiment, rats were anaesthetised, rat testes were removed, and spermatozoon was obtained from the cauda epididymis. It was determined that sperm count and motility, glutathione peroxidase, superoxide dismutase and catalase activities decreased in the methotrexate group, whereas malondialdehyde, tumour necrosis factor-alpha, interleukin-1beta and nuclear kappa factor B expression levels increased. Furthermore, damage to tubulus seminiferus structures and affusion in germ cells was identified. In the methotrexate + chrysin administered group, sperm count improved, biochemical enzyme levels increased, and structural improvements were observed in testicular tubules. These findings demonstrated that chrysin plays a protective role in testicular damage in rats. PMID- 30276847 TI - Humanising patient care through student eyes. PMID- 30276848 TI - Statistical Learning Is Not Age-Invariant During Childhood: Performance Improves With Age Across Modality. AB - Humans are capable of extracting recurring patterns from their environment via statistical learning (SL), an ability thought to play an important role in language learning and learning more generally. While much work has examined statistical learning in infants and adults, less work has looked at the developmental trajectory of SL during childhood to see whether it is fully developed in infancy or improves with age, like many other cognitive abilities. A recent study showed modality-based differences in the effect of age during childhood: While visual SL improved with age, auditory SL did not. This finding was taken as evidence for modality-based differences in SL. However, since that study used auditory linguistic stimuli (syllables), the differential effect of age may have been driven by stimulus type (linguistic vs. non-linguistic) rather than modality. Here, we ask whether age will affect performance similarly in the two modalities when non-linguistic auditory stimuli are used (familiar sounds instead of syllables). We conduct a large-scale study of children's performance on visual and non-linguistic auditory SL during childhood (ages 5-12 years). The results show a similar effect of age in both modalities: Unlike previous findings, both visual and non-linguistic auditory SL improved with age. These findings highlight the stimuli-sensitive nature of SL and suggest that modality based differences may be stimuli-dependent, and that age-invariance may be limited to linguistic stimuli. PMID- 30276849 TI - Influence of the extracellular matrix on water mobility in subcortical gray matter. AB - PURPOSE: Water mobility in tissues is related to the microstructure that modulates diffusion and spin relaxation. Previous work has shown that the extracellular matrix (ECM) impacts water diffusion in cartilage. To investigate if similar contributions to image contrast exist for brain, which is characterized by a substantially lower ECM content, diffusion and relaxation were studied in fixed samples from goat and human thalamus before and after enzymatic digestion of ECM compounds. Selected experiments in human corpus callosum were included for comparing subcortical gray matter and white matter. METHODS: Digestion of matrix components was achieved by treatment with hyaluronidase. Nonlocalized pulsed field gradient measurements were performed with RESULTS: Microstructural alterations associated with hyaluronan digestion did not lead to measurable effects on water diffusion or CONCLUSION: Investigations with very strong gradients did not reveal a detectable effect on water diffusion or PMID- 30276850 TI - Training specialists as consultants integrated into primary care.

PMID- 30276853 TI - Effect of flow-encoding strength on intravoxel incoherent motion in the liver. AB - PURPOSE: To study the impact of variable flow-encoding strength on intravoxel incoherent motion (IVIM) liver imaging of diffusion and perfusion. THEORY: Signal attenuation in DWI arises from (1) intravoxel microvascular blood flow, which depends on the flow-encoding strength alpha (first gradient moment) of the diffusion-encoding waveform, and (2) intravoxel spin diffusion, which depends on the b-value of the diffusion-encoding gradient waveforms alpha and b-value. Both are linked to the diffusion-encoding gradient waveform and conventionally are not independently controlled. METHODS: In this work a convex optimization framework was used to generate gradient waveforms with independent alpha and b-value. Thirty-six unique alpha and b-value sample points from 5 different gradient waveforms were used to reconstruct perfusion fraction (f), coefficient of diffusion (D), and blood velocity standard deviation (Vb ) maps using a recently proposed IVIM model. Faster acquisition strategies were evaluated with 1000 random subsampling strategies of 16, 8, and 4 alpha and b-value. Among the subsampled reconstructions, the sampling schemes that minimized the difference with the fully sampled reconstruction were reported. RESULTS: Healthy volunteers (N = 9) were imaged on a 3T scanner. Liver perfusion and diffusion estimates using the fully sampled IVIM method were f = 0.19 +/- 0.06, D = 1.15 +/- 0.15 CONCLUSION: We demonstrate the IVIM signal's dependence on the b-value, the diffusion-encoding time and the flow-encoding strength and observe in vivo the ballistic regime signature of microperfusion in the liver. This work also demonstrates that using an IVIM model and sampling scheme matched to the ballistic regime, pixel-wise IVIM parameter maps are possible when sampling as few as 4 IVIM signals. PMID- 30276854 TI - Concise synthesis and antibacterial evaluation of novel 3-(1,4-disubstituted 1,2,3-triazolyl)uridine nucleosides. AB - We report herein a simple and efficient synthesis of a new series of antibacterial uridine nucleosides. The strategy involved a sequential silylation/N-glycosylation/N-propargylation procedure of uracil 1 for preparing the dipolarophile 5 in good yield. A series of novel uridine-[1,2,3]triazole nucleosides 6a-j were efficiently synthesized via the copper-catalyzed azide alkyne cycloaddition (CuAAC) from dipolarophile 5 with different selected azides. The reactions were carried out under both conventional and ultrasonic irradiation conditions. In general, improvements were observed when reactions were carried out under sonication. Their antibacterial potential has been evaluated by means of a micro-dilution assay against either Gram-positive or Gram-negative bacteria. Compounds 6i and 6j have shown significant bactericidal activity against Staphylococcus aureus (MIC = 10 and 6 MUM, respectively), and 6h against Escherichia coli (MIC = 8 MUM). Moreover, antibacterial kinetic assays showed that 6i and 6j significantly reduced the S. aureus growth rate at the MIC concentration, after 6 h, compared to their deprotected analogs, 6k and 6l, respectively. Compound 6h also significantly reduced the growth of E. coli. These antibacterial effects may be related to the penetrating properties of these compounds, as revealed by the leakage of nucleic acids from the sensitive strains.

PMID- 30276856 TI - Resident and attending perceptions of direct observation in internal medicine: a qualitative study. AB - OBJECTIVES: Direct observation is the foundation of assessment and learning in competency-based medical education (CBME). Despite its importance, there is significant uncertainty about how to effectively implement frequent and high quality direct observation. This is particularly true in specialties where observation of non-procedural skills is highly valued and presents unique challenges. It is therefore important to understand perceptions of direct observation to ensure successful acceptance and implementation. In this study, we explored perceptions of direct observation in internal medicine. METHODS: We interviewed internal medicine attending physicians (n = 9) and residents (n = 8) at the University of Toronto, purposively sampled for diversity. Using a constructivist grounded theory approach, constant comparative analysis was performed to develop a framework to understand perceptions of direct observation on the clinical teaching units. RESULTS: Participants articulated a narrow perception of what constitutes direct observation, in contrast to their own descriptions of skills that were observed. This resulted in the perception that certain valuable skills that participants felt were routinely observed were nonetheless not 'directly observable', such as clinical reasoning, observed through case presentations and patient care discussions. Differentiating direct observation from informal observation led to overestimation of the time and resource requirements needed to enhance direct observation, which contributed to scepticism and lack of engagement related to CBME implementation. CONCLUSIONS: In an internal medicine training programme, perceptions of what constitutes direct observation can lead to under-recognition and hinder acceptance in workplace based assessment and learning. Our results suggest a reframing of 'direct observation' for residents and attending physicians, by explicitly identifying desired skills in non-procedurally-based specialties. These findings may help CBME-based training programmes improve the process of direct observation, leading to enhanced assessment and learning.

PMID- 30276858 TI - Validation of the inflammatory bowel disease disability index for self-report and development of an item-reduced version. AB - BACKGROUND AND AIM: The Inflammatory Bowel Disease Disability Index (IBD-DI) is a measure of disability in inflammatory bowel disease (IBD). The IBD-DI is validated for use as a clinical interview but not for use as a self-report questionnaire. We aimed to validate the IBD-DI for self-report (IBD-DI-SR) and to reduce the number of items, using IBD patients from two centers. METHODS: Between April and August 2017, ambulatory IBD patients were recruited from Christchurch Hospital, New Zealand and Concord Hospital, Australia. The IBD-DI clinical interview version was compared with a self-report version. Participants were randomized to do the clinical interview or self-report first. Validation of the IBD-DI-SR involved calculating the correlation coefficient between the clinician completed and self-reported version of the IBD-DI and Cronbach's alpha of internal consistency of the IBD-DI-SR. To create an item-reduced version, multiple linear regression was used. The R2 of the model described the overall association between the item-reduced IBD-DI-SR and the IBD-DI. RESULTS: One hundred fourteen patients (57 from Christchurch and 57 from Sydney) completed the IBD-DI-SR validation phase, of whom 63 had Crohn's disease and 51 had ulcerative colitis. The Pearson correlation coefficient between the IBD-DI-SR and IBD-DI is 0.90 (P < 0.001), and Cronbach's alpha of the IBD-DI-SR was 0.86. The item reduced version of the IBD-DI-SR consisted of eight questions instead of 28, explaining 77% of the variance. CONCLUSIONS: The IBD-DI-SR has demonstrated reliability and validity. The item-reduced IBD-DI-SR is a concise self-report instrument for measuring IBD disability, which makes the IBD-DI more widely usable.

PMID- 30276860 TI - Lower respiratory tract infections appear to be the most important risk factor for current asthma in subarctic schoolchildren. AB - AIM: The aim of this study was to identify possible risk factors for current asthma revealed by two studies in Northern Norway in 1985 and 2008 and to evaluate these factors contribution to the increased prevalence of asthma over these 23 years. METHODS: As part of the 'Asthma and allergy study among schoolchildren in Nordland county' we performed a case-control study (70.0% attendance) comparing 153 children with current asthma (cases) to their non asthmatic controls. The results from this 2008 study were compared to a similar case-control study (93.2% attendance) performed in 1985 based on 62 current asthmatics. RESULTS: In 1985 the most important risk factors for current asthma were repeated lower respiratory tract infections (LRTIs) with adjusted odds ratio (aOR) 52.11, together with urticaria ever and atopic disease in the family. In 2008 the most important risk factors were food allergy with aOR7.06, LRTIs during the first 3 years of life with aOR 5.80 and hospitalisation caused by LRTIs. CONCLUSION: In both studies, LRTI was the most important risk factor for current asthma. Whether or not LRTIs have contributed to the increased asthma prevalence in this population over 23 years is unresolved. This article is protected by copyright. All rights reserved. PMID- 30276861 TI - Snus users had high levels of nicotine, cotinine and 3-hydroxycotinine in their breastmilk, and the clearance was slower than in smoking mothers. AB - AIM: Using snus, an oral moist tobacco, has increased among pregnant women in Sweden, the only European Union country where sales are legal. This study evaluated whether snus generated similar concentrations of nicotine and its metabolites in breastmilk to cigarette smoking. METHODS: We analysed 49 breastmilk samples from 33 nursing mother - 13 snus users, six cigarette smokers and 14 controls - for concentrations of nicotine, cotinine and 3-hydroxycotinine. The mothers were recruited at antenatal clinics in Sweden from 2007 to 2012. RESULTS: The median nicotine concentration in breastmilk of the snus users was 38.7 ng/mL (0-137) versus 24.0 ng/mL (0-56) in smokers, with median cotinine levels of 327.6 ng/mL (37-958) versus 164.4 ng/mL and median 3-hydroxycotinine levels of 202.7 ng/mL (28-452) versus 112.4 (0-231), respectively. Nicotine was still detected in the breastmilk of eight of the 13 snus users after abstaining from tobacco for a median duration of 11 hours (0.6-12.5), while the breastmilk of the smokers was nicotine-free after four hours' abstinence. CONCLUSION: Snus users had high levels of nicotine and metabolites in their breastmilk and nicotine was found even after 12.5 hours of abstinence. PMID- 30276862 TI - Delayed calcineurin inhibitor introduction and renal outcomes in liver transplant recipients receiving basiliximab induction. AB - BACKGROUND: To investigate the impact of delayed calcineurin inhibitor (CNI) initiation in liver transplant recipients (LTR) with peri-operative renal insufficiency receiving basiliximab induction, we compared renal outcomes of LTR stratified by the degree of achieved post-operative renal recovery (RR) prior to CNI initiation. METHODS: All adult LTR transplanted between 01/2007 and 12/2015 who received basiliximab were included. Patients who received multi-organ transplantations, were repeat transplant recipients, or expired prior to post operative day (POD) 90 were excluded. The primary outcome of our retrospective analysis was renal function at POD 90. RESULTS: A total of 210 patients were included in our final analysis. Most patients were Caucasian males undergoing liver transplantation for liver disease secondary to hepatitis C virus. Baseline characteristics were similar among the evaluable population. Estimated GFR was significantly higher among patients with the greatest degree of post-operative renal recovery at POD 90; however, this difference did not persist at POD 180. There was no significant difference in incidence or severity of biopsy-proven acute rejection (BPAR) at any measured time point. CONCLUSIONS: Delayed CNI initiation following liver transplantation in patients with post-operative renal insufficiency who receive basiliximab induction does not adversely affect the incidence of BPAR or long-term renal outcomes.

AB - Hollow micro/nanostructured CeO2 -based materials (HMNCMs) have triggered intensive attention as a result of their unique structural traits, which arise from their hollowness and the fascinating physicochemical properties of CeO2 . This attention has led to widespread applications with improved performance. Herein, a comprehensive overview of methodologies applied for the synthesis of various hollow structures, such as hollow spheres, nanotubes, nanoboxes, and multishelled hollow spheres, is provided. The synthetic strategies toward CeO2 hollow structures are classified into three major categories: 1) well-established template-assisted (hard-, soft-, and in situ template) methods; 2) newly emerging self-template approaches, including selective etching, Ostwald ripening, the Kirkendall effect, galvanic replacement, etc.; 3) bottom-up self-organized formation synthesis (namely, oriented attachment and self-deformation). Their underlying mechanisms are concisely described and discussed in detail, the differences and similarities of which are compared transversely and longitudinally. Niche applications of HMNCMs in a wide range of fields including catalysis, energy conversion and storage, sensors, absorbents, photoluminescence, and biomedicines are reviewed. Finally, an outlook of future opportunities and challenges in the synthesis and application of CeO2 -based hollow structures is also presented. PMID- 30276864 TI - Predictors of biochemical recurrence after Retzius-sparing robot-assisted radical prostatectomy: Analysis of 359 cases with a median follow-up period of 26 months. AB - OBJECTIVES: Our aim was to evaluate the predictors of biochemical recurrence after Retzius-sparing robot-assisted radical prostatectomy. METHODS: The study cohort consisted of 359 consecutive non-metastatic prostate cancer patients who underwent Retzius-sparing robot-assisted radical prostatectomy between November 2012 and January 2016. According to the National Comprehensive Cancer Network prostate cancer risk classification, 164 patients (45.7%) had high- or very high risk prostate cancer. No patient received adjuvant therapy until documented biochemical recurrence. Biochemical recurrence-free survival was estimated using the Kaplan-Meier method. Univariable and multivariable Cox proportional hazards regression models were used to determine variables predictive of biochemical recurrence. RESULTS: The median follow-up period was 26 months (interquartile range 19-38 months). The overall biochemical recurrence rate was 14.8%, and the median time to biochemical recurrence was 11 months (interquartile range 6-22 months). The 3-year biochemical recurrence-free survival probability was 71.2%, 72.1%, 88.7%, 82.3% and 95.7% in very high-, high-, intermediate-, low- and very low-risk prostate cancer, respectively (log-rank, P < 0.001). On multivariable analysis, preoperative prostate-specific antigen (hazard ratio 1.03, 95% confidence interval 1.02-1.04; P < 0.0001), percentage of maximum core involvement on biopsy (hazard ratio 1.02, 95% confidence interval 1.01-1.03; P = 0.029) and clinical stage >=T3a (hazard ratio 2.12, 95% confidence interval 1.02 4.39; P = 0.043) were predictors of biochemical recurrence, whereas pathological Gleason score >=8 (hazard ratio 5.63, 95% confidence interval 1.62-19.61; P = 0.007) and pathological tumor volume (hazard ratio 1.08, 95% confidence interval 1.04-1.20; P < 0.001) were the main pathological predictors of biochemical recurrence. CONCLUSIONS: Retzius-sparing robot-assisted radical prostatectomy confers effective biochemical recurrence control at the mid-term follow-up period. Preoperative prostate-specific antigen, advanced clinical stage and higher Gleason score were important predictors of biochemical recurrence after Retzius-sparing robot-assisted radical prostatectomy. Long-term oncological safety still needs to be established. PMID- 30276865 TI - Carer coping and resident agitation as predictors of quality of life in care home residents living with dementia: Managing Agitation and Raising Quality of Life (MARQUE) English national care home prospective cohort study. AB - OBJECTIVES: The objectives of the study are (1) to test our primary hypothesis that carers using more dysfunctional coping strategies predict lower quality of life in care home residents living with dementia, and this is moderated by levels of resident agitation, and (2) to explore relationships between carer dysfunctional coping strategy use, agitation, quality of life, and resident survival. METHODS: In the largest prospective cohort to date, we interviewed carers from 97 care home units (baseline, 4, 8, 12, 16 months) about quality of life (DEMQOL-Proxy) and agitation (Cohen-Mansfield Agitation Inventory) of 1483 residents living with dementia. At baseline, we interviewed 1566 carers about coping strategies (Brief COPE), averaging scores across care home units. RESULTS: Carer dysfunctional coping strategies did not predict resident quality of life over 16 months (0.03, 95% CI -0.40 to 0.46). Lower resident quality of life was longitudinally associated with worse Cohen-Mansfield Agitation Inventory score ( 0.25, 95% CI -0.26 to -0.23). Survival was not associated with carer dysfunctional coping, resident quality of life, or agitation scores. CONCLUSIONS: Carer dysfunctional coping did not predict resident quality of life. Levels of resident agitation were consistently high and related to lower quality of life, over 16 months. Lack of association between carer dysfunctional coping and resident quality of life may reflect the influence of the care home or an insensitivity of aggregated coping strategy scores. The lack of relationship with survival indicates that agitation is not explained mainly by illness. Scalable interventions to reduce agitation in care home residents living with dementia are urgently needed. PMID- 30276866 TI - Long-term effect of migration background on the development of physical fitness among primary school children. AB - BACKGROUND: Children with a low socioeconomic status and migration background are more likely to exhibit unfavorable health behavior patterns and higher BMI scores as well as lower physical activity and physical fitness. AIM: To evaluate the effect of migration background on the development of physical fitness among primary school children from first to third grade. METHODS: In this longitudinal study, height, weight, and physical fitness of primary school children from Tyrol/Austria were measured five times over a period of 2.5 years using the German motor performance test DMT 6-18 consisting of eight items testing different subdomains of physical fitness. RESULTS: A total of 266 children (45% girls) participated in all five tests, of which 69 (26%) children reported to have a migration background (MB). Mixed-model ANOVA did not reveal a significantly different development of physical fitness (according to the mean total Z-score of DMT 6-18) over time, P = 0.883, partial n2 < 0.01. However, children with MB showed significantly lower physical fitness compared to children without MB, P < 0.001, partial n2 = 0.06. Controlling for BMI and age did not alter the interpretation of the results. Analyses of the single test items revealed significant differences in motor tests involving strength and endurance. CONCLUSION: Primary school children with and without MB significantly increased their physical fitness over time in a comparable manner. However, children with MB showed a significantly lower physical fitness at all test time points, which was only partly explained by a higher mean BMI in children with MB. Children with MB outreached the mean baseline fitness level of children without MB not until the fourth test time point, that is after two years. Therefore, a special focus on physical fitness particularly including strength and endurance capacities should be directed to children with MB already in young ages. PMID- 30276867 TI - Folding 2D Structures into 3D Configurations at the Micro/Nanoscale: Principles, Techniques, and Applications. AB - Compared to their 2D counterparts, 3D micro/nanostructures show larger degrees of freedom and richer functionalities; thus, they have attracted increasing attention in the past decades. Moreover, extensive applications of 3D micro/nanostructures are demonstrated in the fields of mechanics, biomedicine, optics, etc., with great advantages. However, the mainstream micro/nanofabrication technologies are planar ones; therefore, they cannot be used directly for the construction of 3D micro/nanostructures, making 3D fabrication at the micro/nanoscale a great challenge. A promising strategy to overcome this is to combine the state-of-the-art planar fabrication techniques with the folding method to produce 3D structures. In this strategy, 2D components can be easily produced by traditional planar techniques, and then, 3D structures are constructed by folding each 2D component to specific orientations. In this way, not only will the advantages of existing planar techniques, such as high precision, programmable patterning, and mass production, be preserved, but the fabrication capability will also be greatly expanded without complex and expensive equipment modification/development. The goal here is to highlight the recent progress of the folding method from the perspective of principles, techniques, and applications, as well as to discuss the existing challenges and future prospectives. PMID- 30276868 TI - Molecular-targeted therapy in advanced renal cell carcinoma based on pharmacokinetics, pharmacodynamics and pharmacogenetics: A proposed strategy. AB - In advanced renal cell carcinoma, a transition of drug therapies from cytokines to molecular-targeted drugs and immune-oncology drugs provides more clinical benefits to patients, while adequate management is required for various and sometimes serious adverse events. At present, the relationship between the pharmacokinetics of many drugs and their effectiveness or adverse events has been elucidated, and therapeutic drug monitoring is being applied to some immunosuppressive, anti-epileptic and antibacterial drugs in daily clinical practice. Most of the molecular-targeted drugs used in patients with renal cell carcinoma are orally active, and are affected by absorption and disposition, which can be different for each individual. The monitoring of the circulating drug concentration could be beneficial to patients by providing information for the adjustment of drug dose and the maintenance of a therapeutic plasma concentration range. Genetic polymorphisms are known to be involved in pharmacokinetics, and cause individual differences in clinical efficacy and adverse events. Therefore, a more scientific strategy should be used in regard to the treatment of patients with advanced renal cell carcinoma treated with molecular-targeted drugs by accumulating evidence on pharmacodynamics and pharmacogenetics. PMID- 30276869 TI - Highlights and recent developments in food and drug allergy, and anaphylaxis in EAACI Journals (2017). AB - This review highlights research advances and important achievements in food allergy, anaphylaxis, and drug allergy that were published in the Journals of the European Academy of Allergy and Clinical Immunology (EAACI) in 2017. Food allergy and anaphylaxis research have continued to rapidly accelerate, with increasing numbers of outstanding developments in 2017. We saw new studies on the mechanisms, diagnosis, prevention of food allergy, and novel food allergens. Drug hypersensitivity, as well as hereditary angioedema, has been highlighted in the present review as the focus of recent developments. The EAACI owns three journals: Allergy, Pediatric Allergy and Immunology (PAI), and Clinical and Translational Allergy (CTA). One of the major goals of the EAACI is to support health promotion in which prevention of allergy and asthma plays a critical role and to disseminate the knowledge of allergy to all stakeholders including the EAACI junior members. This paper summarizes the achievements of 2017 in anaphylaxis, and food and drug allergy. PMID- 30276870 TI - De novo donor-specific HLA antibodies in heart transplantation: Do transient de novo DSA confer the same risk as persistent de novo DSA? AB - BACKGROUND: It is estimated that 25%-35% of heart transplant recipients develop de novo donor-specific antibodies (dnDSA). One factor that appears to play a role in clinical outcomes is DSA persistence. The objective of this study was to determine the incidence of transient and persistent dnDSA in a Canadian heart transplant population and to evaluate their impact on coronary allograft vasculopathy (CAV), graft function, and mortality. METHODS: A retrospective study of consecutive adult and transitioned pediatric heart transplant recipients (2008 2015) in Toronto was performed. Clinical demographics were collected prospectively. HLA antibody testing was performed using Luminex single antigen assays. In statistical analysis, dnDSA was modeled as a time dependent covariate. RESULTS: During a median follow-up of 4.1 years, dnDSA were detected in 42 (23%) with a median time to detection of 329 days (156-740); 27 (64%) developed persistent dnDSA. Persistent dnDSA conferred an increased risk of death with a HR 4.0 (95%CI 1.4-12.1) when adjusted recipient age, CAV, and cytomegalovirus status. CONCLUSIONS: Transient dnDSA were not associated with adverse outcomes after heart transplantation. This suggests that transient dnDSA may not require enhanced immunosuppression, increased HLA antibody monitoring, or additional physiological assessment. By knowing the transient dnDSA status, clinicians may minimize both recipient morbidity and cost without increasing harm. PMID- 30276871 TI - Fabrication of Single-Atom Catalysts with Precise Structure and High Metal Loading. AB - In recent years, single-atom catalysts (SACs) have attracted particular interest and have been demonstrated to be a promising material in energy conversion and chemical transformation due to their optimal atom utilization and unique size quantum effect. The development of a versatile and simple synthetic approach for SACs is important for further investigation of their properties. In this regard, several physical and chemical methods have been developed to access SACs by varying the interaction between metal centers and the coordination defects of the supports. The common challenges for SACs in industrial applications are accurate control over the local structure of single sites and increasing the active-site density. On one hand, the rational design of the atomic structure is decisive to their intrinsic activity, which will affect the adsorption and activation of reactants over the single sites. On the other hand, increasing the metal loading of SACs would largely enhance the density of active sites and the corresponding mass activity, especially for industrial applications. Here, approaches to the synthesis of SACs-focusing on these two challenges-are highlighted. PMID- 30276872 TI - Longitudinal associations of physical activity and sedentary time with cardiometabolic risk factors in children. AB - BACKGROUND: There are few prospective studies on the associations of changes in objectively measured vigorous physical activity (VPA? ), moderate-to-vigorous physical activity (MVPA? ), light physical activity (LPA? ), and sedentary time (ST? ) with changes in cardiometabolic risk factors (? ) in children. We therefore investigated these relationships among children. METHODS: The participants were a population sample of 258 children aged 6-8 years followed for 2 years. We assessed PA and ST by a combined heart rate and movement sensor; computed continuous age- and sex-adjusted z-scores for waist circumference, blood pressure, and fasting insulin, glucose, triglycerides, and high-density lipoprotein (HDL) cholesterol; and constructed a cardiometabolic risk score (CRS) of these risk factors. Data were analyzed using linear regression models adjusted for age, sex, the explanatory and outcome variables at baseline, and puberty. RESULTS: VPA? associated inversely with CRS? (beta = -0.209, P = 0.001), body fat percentage (BF%)? (beta = -0.244, P = 0.001), insulin? (beta = -0.220, P = 0.001), and triglycerides? (beta = -0.164, P = 0.012) and directly with HDL cholesterol? (beta = 0.159, P = 0.023). MVPA? associated inversely with CRS? (beta = -0.178, P = 0.012), BF%? (beta = -0.298, P = <0.001), and insulin? (beta = -0.213, P = 0.006) and directly with HDL cholesterol? (beta = 0.184, P = 0.022). LPA? only associated negatively with CRS? (beta = -0.163, P = 0.032). ST? associated directly with CRS? (beta = 0.218, P = 0.003), BF%? (beta = 0.212, P = 0.016), and insulin? (beta = 0.159, P = 0.049). CONCLUSIONS: Increased VPA and MVPA and decreased ST were associated with reduced overall cardiometabolic risk and major individual risk factors. Change in LPA had weaker associations with changes in these cardiometabolic risk factors. Our findings suggest that increasing at least moderate-intensity PA and decreasing ST decrease cardiometabolic risk in children. PMID- 30276873 TI - Light-Activated Nanoprobes for Biosensing and Imaging. AB - Fluorescent nanoprobes are indispensable tools to monitor and analyze biological species and dynamic biochemical processes in cells and living bodies. Conventional nanoprobes have limitations in obtaining imaging signals with high precision and resolution because of the interference with biological autofluorescence, off-target effects, and lack of spatiotemporal control. As a newly developed paradigm, light-activated nanoprobes, whose imaging and sensing activity can be remotely regulated with light irradiation, show good potential to overcome these limitations. Herein, recent research progress on the design and construction of light-activated nanoprobes to improve bioimaging and sensing performance in complex biological systems is introduced. First, recent innovative strategies and their underlying mechanisms for light-controlled imaging are reviewed, including photoswitchable nanoprobes and phototargeted nanosystems. Subsequently, a short highlight is provided on the development of light activatable nanoprobes for biosensing, which offer possibilities for the remote control of biorecognition and sensing activity in a precise manner both temporally and spatially. Finally, perspectives and challenges in light-activated nanoprobes are commented. PMID- 30276874 TI - Evaluating the role of tissue microRNA-27b as a diagnostic marker for oral lichen planus and possible correlation with CD8. AB - BACKGROUND: MicroRNA-27b (miR27b) is a small, non-coding RNA that is involved in physiological keratinocyte differentiation and regulating inflammatory processes. We performed this study to investigate the value of miR27b as a diagnostic marker for oral lichen planus (OLP) and the correlation between CD8 (cytotoxic T-cell marker) and miR27b tissue expression in OLP patients. METHODS: Forty participants (including 20 OLP patients and 20 controls) underwent oral biopsy. The obtained specimens were examined by immunostaining and quantitative RT-PCR for CD8 and miR27b tissue expression, respectively. We used the Spearman rank correlation test to evaluate the correlation between both variables. RESULTS: Our analysis showed that in comparison with healthy tissues, OLP tissue samples exhibited significantly higher CD8 levels (P < 0.01), as well as a significant downregulation of miR27b expression (P < 0.0001). Upon comparing different OLP subgroups, no significant difference was detected in terms of miR27b expression; however, the tissue levels of CD8 varied significantly (highest in the erosive subgroup and lowest in the papular/plaque/reticular subgroup). The Spearman rank analysis showed a negative correlation between tissue expression of miR27b and CD8; however, this was not statistically significant (P > 0.05). Further, the receiver operating characteristic curve of tissue miR27b as an OLP biomarker revealed 100% sensitivity and 65% specificity at cutoff value of 4.4. CONCLUSION: This study demonstrated increased CD8 levels and downregulation of miR27b in OLP tissues, compared to healthy tissues. Moreover, it revealed the potential of miR27b as an OLP disease biomarker. The possible negative correlation between CD8 and miR27b tissue expression requires further investigation in larger studies. PMID- 30276875 TI - Vascular depression and the death of Queen Victoria. AB - OBJECTIVES: The aim of this article was to examine relationships between the neurological events that were the immediate cause of the death of Queen Victoria and the late-life depression that preceded it. METHODS/DESIGN: The authors closely reviewed the surviving medical notes of Queen Victoria's personal physician, Sir James Reid,Bt. recorded during the Queen's last 10 days of life. These notes were summarized in a chronological narrative and their implications considered in light of current concepts of vascular depression. RESULTS: The depression that Queen Victoria experienced over the 5 months prior to her death and during her final 10 days from 13 January 1901 until 22 January likely had a vascular etiology. CONCLUSIONS: Although conclusions from this study are necessarily speculative given the lack of neuroimaging and other diagnostic tools available in 1901, it emerged that Queen Victoria had experienced early-onset depression followed in later life by an acute depressive episode associated with vascular risk factors and personal losses, a sequence also encountered by today's geriatricians. In addition, etiological connections between the Queen's early onset and late-life depressions appeared probable. Underlined for contemporary practitioners are the suffering experienced by patients with vascular depression at the end of their lives, as well as the struggles of physicians like Sir James Reid to provide clinical wisdom and emotional support. PMID- 30276876 TI - Erratum. PMID- 30276878 TI - Surface Effect on 2D Hybrid Perovskite Crystals: Perovskites Using an Ethanolamine Organic Layer as an Example. AB - Despite the remarkable progress of optoelectronic devices based on hybrid perovskites, there are significant drawbacks, which have largely hindered their development as an alternative of silicon. For instance, hybrid perovskites are well-known to suffer from moisture instability which leads to surface degradation. Nonetheless, the dependence of the surface effect on the moisture stability and optoelectronic properties of hybrid perovskites has not been fully investigated. In this work, the influence of the surface effect of 2D layered perovskites before and after mechanical exfoliation, representing rough and smooth surfaces of perovskite crystals, are studied. It is found that the smooth 2D perovskite is less sensitive to ambient moisture and exhibits a considerably low dark current, which outperforms the rough perovskites by 23.6 times in terms of photodetectivity. The superior moisture stability of the smooth perovskites over the rough perovskites is demonstrated. Additionally, ethanolamine is employed as an organic linker of the 2D layered perovskite, which further improves the moisture stability. This work reveals the strong dependence of the surface conditions of 2D hybrid perovskite crystals on their moisture stability and optoelectronic properties, which are of utmost importance to the design of practical optoelectronic devices based on hybrid perovskite crystals. PMID- 30276879 TI - In Situ Li3 PS4 Solid-State Electrolyte Protection Layers for Superior Long-Life and High-Rate Lithium-Metal Anodes. AB - A thin and adjustable Li3 PS4 (LPS) solid-state electrolyte protection layer on the surface of Li is proposed to address the dynamic plating/stripping process of Li metal. The LPS interlayer is formed by an in situ and self-limiting reaction between P4 S16 and Li in N-methyl-2-pyrrolidone. By increasing the concentration of P4 S16 , the thickness of the LPS layer can be adjusted up to 60 nm. Due to the high ionic conductivity and low electrochemical activity of Li3 PS4 , the intimate protection layer of LPS can not only prevent the formation of Li dendrites, but also reduces parasitic side reactions and improves the electrochemical performance. As a result, symmetric cells with the LPS protection layer can deliver stable Li plating/stripping for 2000 h. Full cells assembled with the LPS-protected Li exhibit two times higher capacity retention in Li-S batteries (~800 mAh g-1 ) at 5 A g-1 for over 400 cycles compared to their bare Li counterparts. Furthermore, high rate performances can be achieved with Li LPS/LiCoO2 cells, which are capable of cycling at rates as high as 20 C. This innovative and scalable approach to stabilizing the Li anode can serve as a basis for the development of next-generation high-performance lithium-metal batteries. PMID- 30276880 TI - Nanoparticle-Conjugate TLR7/8 Agonist Localized Immunotherapy Provokes Safe Antitumoral Responses. AB - Localized therapeutic modalities that subvert the tumor microenvironment from immune-suppressive to pro-immunogenic can elicit systemic antitumor immune responses that induce regression of directly treated as well as nontreated distal tumors. A key toward generating robust antitumor T cell responses is the activation of dendritic cells (DCs) in the tumor microenvironment. Treatment with agonists triggering various pattern recognition receptors is very efficient to activate DCs, yet suffers from the induction of serious immune-related adverse effects, which is closely linked to their unfavorable PK/PD profile causing systemic immune activation and cytokine release. Here, it is reported that nanoparticle conjugation of a highly potent TLR7/8 agonist restricts immune activation to the tumor bed and its sentinel lymph nodes without hampering therapeutic antitumor efficacy. On a mechanistic level, it is confirmed that localized treatment with a nanoparticle-conjugated TLR7/8 agonist leads to potent activation of DCs in the sentinel lymph nodes and promotes proliferation of tumor antigen-specific CD8 T cells. Furthermore, therapeutic improvement upon combination with anti-PDL1 checkpoint inhibition and Flt3L, a growth factor that expands and mobilizes DCs from the bone marrow, is demonstrated. The findings provide a rational base for localized tumor engineering by nanomedicine strategies that provide spatial control over immune-activation. PMID- 30276881 TI - Near-Infrared Ternary Tandem Solar Cells. AB - The paucity of near-infrared (NIR) organic materials with high absorption at long wavelengths, combined with large diffusion lengths and charge mobilities, is an impediment to progress in achieving high-efficiency organic tandem solar cells. Here a subcell is employed within a series tandem stack that comprises a solution processed ternary blend of two NIR-absorbing nonfullerene acceptors and a polymer donor combined with a small-molecular-weight, short-wavelength fullerene-based subcell grown by vacuum thermal evaporation. The ternary cell achieves a power conversion efficiency of 12.6 +/- 0.3% with a short-circuit current of 25.5 +/- 0.3 mA cm-2 , an open-circuit voltage of 0.69 +/- 0.01 V, and a fill factor of 0.71 +/- 0.01 under 1 sun, AM 1.5G spectral illumination. The success of this device is a result of the nearly identical offset energies between the lowest unoccupied molecular orbitals (LUMOs) of the donors with the highest occupied molecular orbital (HOMO) of the acceptor, resulting in a high open-circuit voltage. A tandem structure with an antireflection coating combining these subcells demonstrates a power conversion efficiency of 15.4 +/- 0.3%. PMID- 30276882 TI - "Unleaded" Perovskites: Status Quo and Future Prospects of Tin-Based Perovskite Solar Cells. AB - The tremendous interest focused on organic-inorganic halide perovskites since 2012 derives from their unique optical and electrical properties, which make them excellent photovoltaic materials. Pb-based halide perovskite solar cells, in particular, currently stand at a record efficiency of ~23%, fulfilling their potential toward commercialization. However, because of the toxicity concerns of Pb-based perovskite solar cells, their market prospects are hindered. In principle, Pb can be replaced with other less-toxic, environmentally benign metals. Sn-based perovskites are thus the far most promising alternative due to their very similar and perhaps even superior semiconductor characteristics. After years of effort invested in Sn-based halide perovskites, sufficient breakthroughs have finally been achieved that make them the next runners up to the Pb halide perovskites. To help the reader better understand the nature of Sn-based halide perovskites, their optical and electrical properties are systematically discussed. Recent progress in Sn-based perovskite solar cells, focusing mainly on film fabrication methods and different device architectures, and highlighting roadblocks to progress and opportunities for future work are reviewed. Finally, a brief overview of mixed Sn/Pb-based systems with their anomalous yet beneficial optical trends are discussed. The current challenges and a future outlook for Sn based perovskites are discussed. PMID- 30276883 TI - Molybdenum Carbide Nanodots Enable Efficient Electrocatalytic Nitrogen Fixation under Ambient Conditions. AB - Electrocatalytic nitrogen fixation is considered a promising approach to achieve NH3 production. However, due to the chemical inertness of nitrogen, it is necessary to develop efficient catalysts to facilitate the process of nitrogen reduction. Here, molybdenum carbide nanodots embedded in ultrathin carbon nanosheets (Mo2 C/C) are developed to serve as a catalyst candidate for highly efficient and robust N2 fixation through an electrocatalytic nitrogen reduction reaction (NRR). The as-synthesized Mo2 C/C nanosheets show excellent catalytic performance with a high NH3 yield rate (11.3 ug h-1 mg-1 Mo2C ) and Faradic efficiency (7.8%) for NRR under ambient conditions. More importantly, the isotopic experiments using 15 N2 as a nitrogen source confirm that the synthesized ammonia is derived from the direct supply of nitrogen. This result also demonstrates the possibility of high-efficiency nitrogen reduction even though accompanied with vigorous hydrogen evolution. PMID- 30276884 TI - Examining differences in neuropsychiatric symptom factor trajectories in empirically derived mild cognitive impairment subtypes. AB - OBJECTIVE: The aim of this study was to examine neuropsychiatric symptom (NPS) factor severity progression over time in empirically derived (ED) mild cognitive impairment (MCI) subtypes. METHODS: Participants in the Alzheimer's Disease Neuroimaging Initiative study diagnosed with MCI by Alzheimer's Disease Neuroimaging Initiative protocol using conventional clinical (CC) criteria (n = 788) were reclassified using cluster analysis as amnestic, dysnomic, dysexecutive MCI, or cluster-derived normal (CC-Normal) using empirical criteria. Cognitively normal (CN) participants (n = 207) were also identified. The Neuropsychiatric Inventory-Questionnaire (NPI-Q) was administered from baseline through 48-month follow-up. Exploratory factor analysis was completed to determine the NPI-Q factor structure at 6-month follow-up. Multilevel modeling was used to determine NPI-Q symptom severity factor and apathy symptom progression over time by cognitive subtype. RESULTS: The exploratory factor analysis revealed that the NPI Q consisted of 2 factors: hyperactivity/agitation and mood symptoms. Using clinical and empirical criteria, all MCI groups were identified as having more severe hyperactivity/agitation symptoms than CN participants. However, only the amnestic MCI group identified using empirical criteria showed an increase in symptom severity over time relative to CN participants. Mood factor and apathy symptoms were found to be more severe in dysexecutive and amnestic groups in both models. Similarly, both models identified a significant worsening of mood and apathy symptoms over time for dysexecutive and amnestic groups relative to CN participants. CONCLUSIONS: This study provides further support that empirical criteria aid in examining the progression of clinical characteristics associated with MCI. Further, it helps to identify which MCI subtypes may be at higher risk for NPS progression. PMID- 30276885 TI - Butylamine-Catalyzed Synthesis of Nanocrystal Inks Enables Efficient Infrared CQD Solar Cells. AB - The best-performing colloidal-quantum-dot (CQD) photovoltaic devices suffer from charge recombination within the quasi-neutral region near the back hole extracting junction. Graded architectures, which provide a widened depletion region at the back junction of device, could overcome this challenge. However, since today's best materials are processed using solvents that lack orthogonality, these architectures have not yet been implemented using the best performing CQD solids. Here, a new CQD ink that is stable in nonpolar solvents is developed via a neutral donor ligand that functions as a phase-transfer catalyst. This enables the realization of an efficient graded architecture that, with an engineered band-alignment at the back junction, improves the built-in field and charge extraction. As a result, optimized IR CQD solar cells (Eg ~ 1.3 eV) exhibiting a power conversion efficiency (PCE) of 12.3% are reported. The strategy is applied to small-bandgap (1 eV) IR CQDs to augment the performance of perovskite and crystalline silicon (cSi) 4-terminal tandem solar cells. The devices show the highest PCE addition achieved using a solution-processed active layer: a value of +5% when illuminated through a 1.58 eV bandgap perovskite front filter, providing a pathway to exceed PCEs of 23% in 4T tandem configurations with IR CQD PVs. PMID- 30276886 TI - Graphene/Organic Semiconductor Heterojunction Phototransistors with Broadband and Bi-directional Photoresponse. AB - A graphene-semiconductor heterojunction is very attractive for realizing highly sensitive phototransistors due to the strong absorption of the semiconductor layer and the fast charge transport in the graphene. However, the photoresponse is usually limited to a narrow spectral range determined by the bandgap of the semiconductor. Here, an organic heterojunction (C60 /pentacene) is incorporated on graphene to realize a broadband (405-1550 nm) phototransistor with a high gain of 5.2 * 105 and a response time down to 275 us. The visible and near-infrared parts of the photoresponsivity (9127 A W-1 @650 nm and 1800 A W-1 @808 nm) come from the absorption of the organic layer and the graphene, respectively. For the first time, a bi-directional (positive and negative) photoresponse is demonstrated at different wavelengths, due to the opposite charge transfer direction of the photoexcited carriers enforced by the unique band alignment. Such tunability will enable new functionalities such as large-scale real-time optical image and infrared focal plane array detection in the future. PMID- 30276887 TI - Efficient Nonfullerene Organic Solar Cells with Small Driving Forces for Both Hole and Electron Transfer. AB - State-of-the-art organic solar cells (OSCs) typically suffer from large voltage loss (Vloss ) compared to their inorganic and perovskite counterparts. There are some successful attempts to reduce the Vloss by decreasing the energy offsets between the donor and acceptor materials, and the OSC community has demonstrated efficient systems with either small highest occupied molecular orbital (HOMO) offset or negligible lowest unoccupied molecular orbital (LUMO) offset between donors and acceptors. However, efficient OSCs based on a donor/acceptor system with both small HOMO and LUMO offsets have not been demonstrated simultaneously. In this work, an efficient nonfullerene OSC is reported based on a donor polymer named PffBT2T-TT and a small-molecular acceptor (O-IDTBR), which have identical bandgaps and close energy levels. The Fourier-transform photocurrent spectroscopy external quantum efficiency (FTPS-EQE) spectrum of the blend overlaps with those of neat PffBT2T-TT and O-IDTBR, indicating the small driving forces for both hole and electron transfer. Meanwhile, the OSCs exhibit a high electroluminescence quantum efficiency (EQEEL ) of ~1 * 10-4 , which leads to a significantly minimized nonradiative Vloss of 0.24 V. Despite the small driving forces and a low Vloss , a maximum EQE of 67% and a high power conversion efficiency of 10.4% can still be achieved.

AB - Crystalline nanoporous materials with uniform porous structures, such as zeolites and metal-organic frameworks (MOFs), have proven to be ideal supports to encapsulate ultrasmall metal nanoparticles (MNPs) inside their void nanospaces to generate high-efficiency nanocatalysts. The nanopore-encaged metal catalysts exhibit superior catalytic performance as well as high stability and catalytic shape selectivity endowed by the nanoporous matrix. In addition, the synergistic effect of confined MNPs and nanoporous frameworks with active sites can further promote the catalytic activities of the composite catalysts. Herein, recent progress in nanopore-encaged metal nanocatalysts is reviewed, with a special focus on advances in synthetic strategies for ultrasmall MNPs (<5 nm), clusters, and even single atoms confined within zeolites and MOFs for various heterogeneous catalytic reactions. In addition, some advanced characterization methods to elucidate the atomic-scale structures of the nanocatalysts are presented, and the current limitations of and future opportunities for these fantastic nanocatalysts are also highlighted and discussed. The aim is to provide some guidance for the rational synthesis of nanopore-encaged metal catalysts and to inspire their further applications to meet the emerging demands in catalytic fields.

AB - Glycan-protein interactions play an important role in a broad range of physiological processes, raising interest to elucidate the structural interplay. Yet, their dynamic nature limits the analysis by crystallography, whereas NMR spectroscopy suffers from the low 1 H dispersion of glycans. Therefore, their sparse fluorination and NMR screening by 1D Saturation Transfer Difference with relay to 19 F (STDreF) was previously proposed to exploit the superior dispersion in 19 F NMR spectroscopy. A new 2D STD-TOCSYreF experiment is presented here that enables comprehensive epitope mapping of fluorinated glycans by combining the spectral resolution of 19 F with the spatial resolution and coverage of 1 H. For an illustration, the 2-deoxy-2-fluoro derivative of the N-glycan core trimannoside was synthesised and its recognition of Pisum sativum agglutinin by either of the two terminal mannose residues was confirmed. Going beyond the crystallographic information, the 2D STD-TOCSYreF spectrum moreover visualised collateral contacts from the branching mannose and allowed to assess the ratio of both co-existing binding modes through the alpha1,3- (67 %) and alpha1,6-linked (33 %) terminal mannose moieties.

AB - Exposure to social stress alters the response to drugs of abuse of experimental animals. Changes in the glutamatergic system seem to play a role in the effects of social defeat stress on the rewarding properties of cocaine and amphetamine. The aim of the present study was to evaluate the involvement of N-methyl-D aspartate (NMDA) and alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) glutamate receptors in the effects of social defeat on the conditioned place preference induced by 3,4-methylenedioxymethamphetamine (MDMA). Our hypothesis was that changes in these receptors could mediate the effects of social defeat on MDMA reward. Young adult male mice were exposed to an episode of social defeat with an aggressive conspecific immediately before each conditioning session with MDMA (1.25 mg/kg, four sessions on alternating days). According to the treatment received before defeats, six groups were used: saline, 5 or 10 mg/kg of memantine (NMDA antagonist) and 0.25, 1 or 5 mg/kg of 6-cyano-7 nitroquinoxaline-2,3-dione (CNQX) (AMPA antagonist). One control group was exposed to exploration before place conditioning. In two additional defeated and control groups, the membrane expression of NMDA and AMPA receptors was determined in the striatum and the hippocampus. Control and memantine-treated groups developed place preference, but not defeated mice treated with saline or CNQX, suggesting that the blockade of NMDA receptors reversed the effects of social defeat. Social defeat decreased the expression of several subunits of NMDA and AMPA receptors, mainly GluN1 and GluA1. These results demonstrated that glutamatergic plasticity is involved in the effects of social defeat stress on MDMA reward.

PMID- 30276893 TI - The small protein MgtS and small RNA MgrR modulate the PitA phosphate symporter to boost intracellular magnesium levels. AB - In response to low levels of magnesium (Mg2+ ), the PhoQP two component system induces the transcription of two convergent genes, one encoding a 31-amino acid protein denoted MgtS and the second encoding a small, regulatory RNA (sRNA) denoted MgrR. Previous studies showed that the MgtS protein interacts with and stabilizes the MgtA Mg2+ importer to increase intracellular Mg2+ levels, while the MgrR sRNA base pairs with the eptB mRNA thus affecting lipopolysaccharide modification. Surprisingly, we found overexpression of the MgtS protein also leads to induction of the PhoRB regulon. Studies to understand this activation showed that MgtS forms a complex with a second protein, PitA, a cation-phosphate symporter. Given that the additive effect of ?mgtA and ?mgtS mutations on intracellular Mg2+ concentrations seen previously is lost in the ?pitA mutant, we suggest that MgtS binds to and prevents Mg2+ leakage through PitA under Mg2+ limiting conditions. Consistent with a detrimental role of PitA in low Mg2+ , we also observe MgrR sRNA repression of PitA synthesis. Thus, PhoQP induces the expression of two convergent small genes in response to Mg2+ limitation whose products act to modulate PitA at different levels to increase intracellular Mg2+ .

AB - Nucleocapsid protein 7 (NCp7) is an attractive target for anti-HIV drug development. Here we found that ruthenium complexes are reactive to NCp7 and various Ru-agents exhibit significantly different reactivity. Interestingly, the zinc-finger domains of NCp7 also demonstrate different affinity to Ru-complexes; the C-terminal domain is much more reactive than the N-terminal domain. Each zinc finger domain of NCp7 binds up to three Ru-motifs, and the ruthenium binding causes zinc-ejection from NCp7 and disrupts the protein folding. Therefore, ruthenium complexes interfere with the DNA binding of NCp7 and interrupt the protein function. The different reactivity of Ru-agents suggests a feasible strategy for improving the targeting of NCp7 by ligand design. This work provides an insight into the mechanism of ruthenium complex with NCp7, and suggests more potential application of ruthenium drugs.

The Protonation State and Conformation of the Reaction Intermediate of Chitinase Enzymes Revisited. AB - The enzymatic hydrolysis of chitin, one of the most abundant carbohydrates in nature, is achieved by chitinases, enzymes of increasing importance in biomedicine and industry. Unlike most retaining glycosidases, family GH18 chitinases follow a substrate-assisted mechanism in which the 2-acetamido group of one N-acetylglucosamine monomer, rather than a basic residue of the enzyme, reacts with the sugar anomeric carbon, forming an intermediate that has been described as an oxazolinium ion. Based on QM/MM metadynamics simulations on chitinase B from Serratia marcescens, we show that the reaction intermediate of GH18 chitinases features instead a neutral oxazoline in a 4 C1 /4 H5 conformation, with an oxazolinium ion being formed on the pathway towards the reaction products. The role of a well-defined hydrogen-bond network that operates around the N-acetyl group, orchestrating catalysis by protonation events, is discussed. PMID- 30276897 TI - Brain metabolism under different anesthetic conditions using hyperpolarized [1-13 C]pyruvate and [2-13 C]pyruvate. AB - Carbon-13 NMR spectroscopy (13 C MRS) offers the unique capability to measure brain metabolic rates in vivo. Hyperpolarized 13 C reduces the time required to assess brain metabolism from hours to minutes when compared with conventional 13 C MRS. This study investigates metabolism of hyperpolarized [1-13 C]pyruvate and [2-13 C]pyruvate in the rat brain in vivo under various anesthetics: pentobarbital, isoflurane, alpha-chloralose, and morphine. The apparent metabolic rate from pyruvate to lactate modeled using time courses obtained after injection of hyperpolarized [1-13 C]pyruvate was significantly greater for isoflurane than for all other anesthetic conditions, and significantly greater for morphine than for alpha-chloralose. The apparent metabolic rate from pyruvate to bicarbonate was significantly greater for morphine than for all other anesthetic conditions, and significantly lower for pentobarbital than for alpha-chloralose. Results show that relative TCA cycle rates determined from hyperpolarized 13 C data are consistent with rates previously measured using conventional 13 C MRS under similar anesthetic conditions, and that using morphine for sedation greatly improves detection of downstream metabolic products compared with other anesthetics. PMID- 30276898 TI - Programming Niche Accessibility and In Vitro Stemness with Intercellular DNA Reactions. AB - Stem cells generally exist in low abundance and tend to lose stemness in the absence of self-renewal signals. While extracellular-matrix-mimicking techniques have been developed to support stem cell proliferation, the lack of niche cells in these synthetic systems often hampers continuous stem cell expansion and maintenance of pluripotency, which are indispensable for regenerative medicine. Here, an intercellular DNA-reaction-programmed ESPN (expansion of stem cells with pairing niches) strategy is developed for 3D culture of mammary stem cells (MaSCs). Boolean logic operations are implemented to confer DNA-programmed mechanical signaling and genetically engineered morphogen signaling by niche cells, resulting in sustained expansion of MaSCs in vitro. The creation of stem cell niches improves the proliferation of pluripotent cells by four times during one-week culture. This method thus provides a novel approach for logical regulation of stemness and proliferation of stem cells for biomedicine. PMID- 30276899 TI - Solvent-Free Mechanochemical Preparation of Hierarchically Porous Carbon for Supercapacitor and Oxygen Reduction Reaction. AB - Hierarchically porous carbon (HPC) derived from fallen flowers was prepared by a green method of combining solvent-free ball milling with the safe activating agent potassium bicarbonate. By regulating the mass ratio of KHCO3 to biochar, the as-prepared HPC materials possess high specific surface areas of up to 2147.9 m2 g-1 and abundant hierarchical pores comprised of micro-, meso-, and macropores. The specific capacitances of the HPC materials are able to reach 302.7 F g-1 at a current density of 0.5 A g-1 in 6 m KOH, and the symmetric supercapacitor composed of two identical HPC electrodes shows good stability because 100 % of the specific capacitance is retained after 5000 charge/discharge cycles and 90.5 % of the specific capacitance remains after 12 000 cycles. Nitrogen self-doped HPC materials also show higher electrocatalytic activity and stronger methanol tolerance for the oxygen reduction reaction than that of the commercial Pt/C catalyst. This preparation method can be extended to the green conversion of other varieties of biomass waste into useful carbon materials. PMID- 30276900 TI - Synthesis of Bis(arylethynyl)pyrrolo[3,2-b]pyrroles and Effect of Intramolecular Charge Transfer on Their Photophysical Behavior. AB - 3,6-Bis(arylethynyl)pyrrolo[3,2-b]pyrroles were synthesized through a two-step procedure involving double direct alkynylation of the electron-rich core followed by Sonogashira coupling. In comparison with the parent tetraarylo-pyrrolo[3,2 b]pyrroles and benzo-fused pyrrolopyrroles, these new dyes showed moderately redshifted absorption. Almost all derivatives showed positive fluorescence solvatochromism and, for the first time, red-emitting pyrrolopyrroles were obtained. Computational studies revealed that, in most cases, there is negligible change in the geometry between ground and excited states. Interestingly, there was a fundamental difference between pyrrolopyrroles possessing electron withdrawing substituents at positions 2 and 5 and their analogs lacking these substituents. The former dyes behaved like dipolar chromophores with the lowest excited state both one-photon and two-photon allowed, which corresponds to intramolecular charge transfer occurring along the branches perpendicular to the pyrrolopyrrole long axis. In compounds lacking electron-withdrawing substituents at positions 2 and 5, intramolecular charge transfer took place along the long axis of pyrrolopyrrole and consequently the one-photon transitions are not two photon allowed. Despite displaying quadrupolar core-to-peripheral intramolecular charge transfer, these derivatives showed two-photon absorption cross sections in the NIR1 region comparable to tetraaryl-pyrrolo[3,2-b]pyrroles lacking pi expansion (up to about 500 GM).

PMID- 30276902 TI - Polydrug use patterns and their impact on relapse among heroin-dependent patients in Shanghai, China. AB - AIMS: To describe the polysubstance use patterns of heroin-dependent patients and to understand the impact of polysubstance use patterns on relapse during the 5 years after completing compulsory rehabilitation programmes. DESIGN: In this secondary analysis, the baseline data of 503 heroin-dependent patients were linked with their 5-year follow-up data from official records. SETTING: Four compulsory rehabilitation centres in Shanghai, China. PARTICIPANTS: A total of 564 heroin-dependent patients who were discharged from Shanghai compulsory rehabilitation facilities in 2007 and 2008 were recruited. Among these, 503 patients with available follow-up records were included in this analysis. MEASUREMENTS: The baseline measurements included the Addiction Severity Index, the Temperament and Character Inventory and the Medical Outcomes Study Social Support Scale. Relapses after discharge from the compulsory rehabilitation centres were extracted monthly from the official electronic record system. Latent class analysis was used to identify different polysubstance use patterns. Associations between the identified latent classes and heroin use and the factors related to relapse during the 5-year follow-up were analysed with the Cox regression model. FINDINGS: Three latent classes were identified in this cohort: (1) alcohol polydrug users (APU; 13.7%), (2) low polydrug users (LPU; 76.5%) and (3) amphetamine-type stimulant polydrug users (ASPU; 9.7%). During the 5-year follow-up, 298 heroin patients relapsed, and the three groups showed different relapse rates (ASPU 69.4 versus LPU 60.5 versus APU 44.9%, P = 0.02). The average durations of abstinence for the three groups differed (ASPU 31.27 +/- 3.41 months versus LPU 36.77 +/- 1.19 months versus APU 42.46 +/- 2.81 months, P = 0.02). Multivariate Cox regression analyses found that the LPU [hazard ratio (HR) = 1.63, 1.06-2.51] and ASPU (HR = 2.10, 1.24-3.56) classes were positively associated with the risk of heroin relapse. CONCLUSION: Polydrug use patterns differ among heroin-dependent patients in compulsory rehabilitation programmes in China. A history of polydrug use may predict heroin relapse risk among patients in those compulsory rehabilitation programmes. PMID- 30276903 TI - Shell Cross-Linked Micelles as Nanoreactors for Enantioselective Three-Step Tandem Catalysis. AB - Functionalized amphiphilic poly(2-oxazoline)-based triblock copolymers that assemble into shell cross-linked micelles (SCMs) are described. These micelles permit the site isolation of three incompatible catalysts through compartmentalization, thereby enabling three-step non-orthogonal tandem processes in one pot. In particular, the acid-catalyzed ketal hydrolysis to prochiral ketones proceeded in the hydrophilic corona, followed by the Rh-catalyzed asymmetric transfer hydrogenation to enantio-enriched alcohols in the cross linked shell, and nucleophilic base-catalyzed acylation in the hydrophobic core. The catalysts are positioned in close proximity on a single micelle support to take advantage of the intramicellar substrate diffusion, yet they are sufficiently spaced apart from each other in physically distinct microenvironments. These compartmentalized micelles are substrate selective and, on a basic level, mimic compartmentalized catalytic architectures found in nature. PMID- 30276904 TI - Electronic and Structural Engineering of Carbon-Based Metal-Free Electrocatalysts for Water Splitting. AB - Since first being reported as possible electrocatalysts to substitute platinum for the oxygen reduction reaction (ORR), carbon-based metal-free nanomaterials have been considered a class of promising low-cost materials for clean and sustainable energy-conversion reactions. However, beyond the ORR, the development of carbon-based catalysts for other electrocatalytic reactions is still limited. More importantly, the intrinsic activity of most carbon-based metal-free catalysts is inadequate compared to their metal-based counterparts. To address this challenge, more design strategies are needed in order to improve the overall performance of carbon-based materials. Herein, using water splitting as an example, some state-of-the-art strategies in promoting carbon-based nanomaterials are summarized, including graphene, carbon nanotubes, and graphitic-carbon nitride, as highly active electrocatalysts for hydrogen evolution and oxygen evolution reactions. It is shown that by rationally tuning the electronic and/or physical structure of the carbon nanomaterials, adsorption of reaction intermediates is optimized, consequently improving the apparent electrocatalytic performance. These strategies may facilitate the development in this area and lead to the discovery of advanced carbon-based nanomaterials for various applications in energy-conversion processes. PMID- 30276905 TI - The impact of blind peer review (team reading) of equivocal/abnormal Papanicolaou smears on inter-reader agreement. AB - OBJECTIVE: Peer review of equivocal/abnormal Papanicolaou smears is a standard internal quality assurance measure in cervical cancer screening laboratories. In 2014, we introduced a new method for peer review involving blinding the identity of the first reader. We present the comparison of different measures of inter reader agreement in 2013 and 2014 in order to measure the impact of blind peer review on possible cognitive biases in reading. METHODS: All suspect slides are proposed for peer review; a single reader's peer reviews are registered independently, with discordant cases discussed for consensus diagnosis. Since 2014, the first reader's name has been blinded to peers. We computed how frequently the initial diagnosis was changed, and how frequently a single reader influenced the final diagnosis when the initial one was changed. We compared kappa of the first reader and that of other readers with final diagnosis. Data from 2013 were compared to those of 2014. RESULTS: The final diagnosis changed in 22.9% of cases (range 16.8%-34.4%) in 2013 and in 26.8% (range 13.9%-35.6%) in 2014 (P = .2). Individual peer diagnoses agreed with final diagnosis in 52.3% (range 41.9%-66.3%) in 2013 and in 50.2% (range 36.0%-65.8%) in 2014 (P = .55). The cytologist having the highest proportion of confirmed diagnoses was also the most influential on final diagnosis, both in 2013 and in 2014. Agreement between first reader and final diagnosis was higher than that of each reader in 2013 and in 2014. CONCLUSIONS: Blinding the identity of the first reader had little or no impact on inter-reader agreement measures in our laboratory. PMID- 30276906 TI - Age-varying effects of cannabis use frequency and disorder on symptoms of psychosis, depression and anxiety in adolescents and adults. AB - AIMS: We tested the age-varying associations of cannabis use (CU) frequency and disorder (CUD) with psychotic, depressive and anxiety symptoms in adolescent and adult samples. Moderating effects of early onset (<= 15 years) and sex were tested. DESIGN: Time-varying effect models were used to assess the significance of concurrent associations between CU and CUD and symptoms of psychosis, depression and anxiety at each age. SETTING AND PARTICIPANTS: Adolescent data (V HYS; n = 662) were collected from a randomly recruited sample of adolescents in Victoria, British Columbia, Canada during a 10-year period (2003-13). Adult cross sectional data (NESARC-III; n = 36 309) were collected from a representative sample from the United States (2012-13). MEASUREMENTS: Mental health symptoms were assessed using self-report measures of diagnostic symptoms. CU was based on frequency of past-year use. Past-year CUD was based on DSM-5 criteria. FINDINGS: For youth in the V-HYS, CU was associated with psychotic symptoms following age 22 [b = 0.13, 95% confidence interval (CI) = 0.002, 0.25], with depressive symptoms from ages 16-19 and following age 25 (b = 0.17, 95% CI = 0.003, 0.34), but not with anxiety symptoms. CUD was associated with psychotic symptoms following age 23 (b = 0.51, 95% CI = 0.01, 1.01), depressive symptoms at ages 19 20 and following age 25 (b = 0.71, 95% CI = 0.001, 1.42) and anxiety symptoms ages 26-27 only. For adults in the NESARC-III, CU was associated with mental health symptoms at most ages [e.g. psychotic symptoms; age 18 (b = 0.22, 95% CI = 0.10, 0.33) to age 65 (b = 0.36, 95% CI = 0.16, 0.56)]. CUD was associated with all mental health symptoms across most ages [e.g. depressive symptoms; age 18 (b = 0.96, 95% CI = 0.19, 1.73) to age 61 (b = 1.11, 95% CI = 0.01, 2.21)]. Interactions with sex show stronger associations for females than males in young adulthood [e.g. V-HYS: CUD * sex interaction on psychotic symptoms significant after age 26 (b = 1.12, 95% CI = 0.02, 2.21)]. Findings were not moderated by early-onset CU. CONCLUSIONS: Significant associations between cannabis use (CU) frequency and disorder (CUD) and psychotic and depressive symptoms in late adolescence and young adulthood extend across adulthood, and include anxiety. PMID- 30276907 TI - Impact of timing of methadone initiation on perinatal outcomes following delivery among pregnant women on methadone maintenance therapy in Ontario. AB - BACKGROUND AND AIMS: Methadone maintenance therapy (MMT) is associated with improved outcomes for children exposed to maternal opioid dependence in utero. We examined Ontario's population of pregnant women on MMT and determined the impact of timing of MMT initiation on perinatal outcomes. DESIGN: Cohort study. SETTING: Ontario, Canada. PARTICIPANTS: Women eligible for public drug benefits and on MMT during pregnancy between 2005 and 2015. MEASUREMENTS: We stratified women based on their timing of MMT initiation: (1) stabilized prior to conception, (2) newly initiated prior to conception, (3) initiation in trimester 1, (4) initiation in trimester 2 or (5) initiation in trimester 3. The primary outcomes in the multivariable logistic regression analysis were key perinatal health indicators: small for gestational age, preterm birth, congenital anomalies, severe maternal morbidity, caesarean section and induced labor. Secondary outcomes were specific to maternal opioid dependence: neonatal abstinence syndrome (NAS), admission to a neonatal intensive care unit (NICU), NAS treatment, removal from mother's custody at hospital discharge and neonatal death. FINDINGS: Among 1842 women on MMT during pregnancy, 87.6% (n = 1614) initiated MMT before conception. Almost a quarter of their infants (22.2%; n = 408) were born small for gestational age, 17.5% (n = 323) were preterm and 5.9% (n = 109) were born with a congenital anomaly. The odds of primary outcomes occurring did not differ based on timing of methadone initiation; however, infants of mothers who initiated methadone during pregnancy had up to a fourfold increase in the odds of social services removal at the hospital [adjusted odds ratio (aOR) range = 3.70-4.19] compared with those whose mothers were stabilized on MMT prior to conception. CONCLUSIONS: Later initiation of methadone maintenance therapy among pregnant women in Ontario, Canada has not been found to be clearly related to most key perinatal adverse health outcomes. PMID- 30276908 TI - Assembly processes of trophic guilds in the root mycobiome of temperate forests. AB - Root-associated mycobiomes (RAMs) link plant and soil ecological processes, thereby supporting ecosystem functions. Understanding the forces that govern the assembly of RAMs is key to sustainable ecosystem management. Here, we dissected RAMs according to functional guilds and combined phylogenetic and multivariate analyses to distinguish and quantify the forces driving RAM assembly processes. Across large biogeographic scales (>1,000 km) in temperate forests (>100 plots), RAMs were taxonomically highly distinct but composed of a stable trophic structure encompassing symbiotrophic, ectomycorrhizal (55%), saprotrophic (7%), endotrophic (3%) and pathotrophic fungi (<1%). Taxonomic community composition of RAMs is explained by abiotic factors, forest management intensity, dominant tree family (Fagaceae, Pinaceae) and root resource traits. Local RAM assemblies are phylogenetically clustered, indicating stronger habitat filtering on roots in dry, acid soils and in conifer stands than in other forest types. The local assembly of ectomycorrhizal communities is driven by forest management intensity. At larger scales, root resource traits and soil pH shift the assembly process of ectomycorrhizal fungi from deterministic to neutral. Neutral or weak deterministic assembly processes are prevalent in saprotrophic and endophytic guilds. The remarkable consistency of the trophic composition of the RAMs suggests that temperate forests attract fungal assemblages that afford functional resilience under the current range of climatic and edaphic conditions. At local scales, the filtering processes that structure symbiotrophic assemblies can be influenced by forest management and tree selection, but at larger scales, environmental cues and host resource traits are the most prevalent forces. PMID- 30276909 TI - UV Light-Responsive Peptide-Based Supramolecular Hydrogel for Controlled Drug Delivery. AB - Low-molecular-weight self-assembled peptides may serve as promising hydrogelators for drug delivery applications by changing their structural network in response to external stimuli. Herein, inspired by the well-studied low-molecular-weight peptide hydrogelator, fluorenyl-methoxycarbonyl-diphenylalanine (Fmoc-FF), a novel peptide is designed and synthesized to include an ultraviolet (UV) sensitive phototrigger. Similar to Fmoc-FF, 6-nitroveratryloxycarbonyl diphenylalanine (Nvoc-FF) self-assembles to form a 3D, self-supporting, nanofibrous hydrogel. The Nvoc-FF hydrogel exhibits good mechanical properties with a storage modulus of 40 kPa. UV irradiation of the Nvoc-FF hydrogel encapsulating insulin-fluorescein isothiocyanate (insulin-FITC) results in the cleavage of Nvoc-FF peptide to produce unmasked FF, thereby facilitating the degradation of the hydrogel and the release of insulin-FITC. This release is in linear correlation to the irradiation time. In the present study, a first insight into this rigid, fibrous, light-responsive hydrogel is provided, allowing the fabrication of a novel drug delivery system for controlled release of large molecules. PMID- 30276910 TI - High intraspecific diversity of Restorer-of-fertility-like genes in barley. AB - Nuclear restorer of fertility (Rf) genes suppress the effects of mitochondrial genes causing cytoplasmic male sterility (CMS), a condition in which plants fail to produce viable pollen. Rf genes, many of which encode RNA-binding pentatricopeptide repeat (PPR) proteins, are applied in hybrid breeding to overcome CMS used to block self-pollination of the seed parent. Here, we characterise the repertoire of restorer-of-fertility-like (RFL) PPR genes in barley (Hordeum vulgare). We found 26 RFL genes in the reference genome ('Morex') and an additional 51 putative orthogroups (POGs) in a re-sequencing data set from 262 barley genotypes and landraces. Whereas the sequences of some POGs are highly conserved across hundreds of barley accessions, the sequences of others are much more variable. High sequence variation strongly correlates with genomic location the most variable genes are found in a cluster on chromosome 1H. A much higher likelihood of diversifying selection was found for genes within this cluster than for genes present as singlets. This work includes a comprehensive analysis of the patterns of intraspecific variation of RFL genes. The RFL sequences characterised in this study will be useful for the development of new markers for fertility restoration loci. PMID- 30276911 TI - Does the nicotine metabolite ratio moderate smoking cessation treatment outcomes in real-world settings? A prospective study. AB - BACKGROUND AND AIMS: In smoking treatment trials comparing varenicline with transdermal nicotine replacement therapy (NRT), stratified by nicotine metabolite (3-hydroxycotinine/cotinine) ratio (NMR), the relative benefit of varenicline is greater among normal rather than slow metabolizers. This study tested if the relative effectiveness of varenicline and NRT is associated with NMR status in a natural treatment setting. A secondary aim was to test if this relationship is moderated by behavioural support. DESIGN: Prospective observational multi-centre study with 4-week and 52-week follow-up. SETTING: Nine English Stop Smoking Services (SSS). PARTICIPANTS: Data came from 1556 smokers (aged >= 16 years) attending SSS between March 2012 and March 2013. INTERVENTIONS: Participants received pharmacotherapy together with behavioural support. MEASUREMENTS: The primary outcome was carbon monoxide-verified continuous abstinence at both follow up times. Main explanatory variables were (1) NMR status [slow (NMR < 0.31, n = 451) versus normal (NMR >= 0.31, n = 1105) metabolizers]; (2) pharmacotherapy (varenicline versus NRT) and (3) behavioural support (individual versus group based treatment). Analyses adjusted for baseline socio-demographic, SSS, mental/physical health and smoking characteristics. FINDINGS: Of participants, 44.2% [95% confidence interval (CI) = 41.7-46.6%] and 8.0% (95% CI = 6.8-9.5%) were continuously abstinent at 4 and 52 weeks. Varenicline was more effective than NRT at 4 weeks (P < 0.001) but only marginally so at 52 weeks (P = 0.061). There was no or inclusive evidence that NMR status moderated relative efficacy of varenicline and NRT at 4- [P = 0.60, Bayes factor (BF) = 0.25] or 52-week follow ups (P = 0.74, BF = 0.73). However, this relationship was moderated by behavioural support (p = 0.012): the relative benefit of varenicline over NRT at 52-week follow-up was greater in slow, not normal, metabolizers receiving group rather than individual support (P = 0.012). CONCLUSIONS: In a real-world setting, the nicotine metabolite ratio status of treatment-seeking smokers does not appear to contribute substantially to the differential effectiveness of varenicline and nicotine replacement therapy in Stop Smoking Services, when both pharmacotherapy and behavioural support are self-selected.

AB - A thorough understanding of ecological networks relies on comprehensive information on trophic relationships among species. Since unpicking the diet of many organisms is unattainable using traditional morphology-based approaches, the application of high-throughput sequencing methods represents a rapid and powerful way forward. Here, we assessed the application of DNA metabarcoding with nearly universal primers for the mitochondrial marker cytochrome c oxidase I in defining the trophic ecology of adult brown shrimp, Crangon crangon, in six European estuaries. The exact trophic role of this abundant and widespread coastal benthic species is somewhat controversial, while information on geographical variation remains scant. Results revealed a highly opportunistic behaviour. Shrimp stomach contents contained hundreds of taxa (>1,000 molecular operational taxonomic units), of which 291 were identified as distinct species, belonging to 35 phyla. Only twenty ascertained species had a mean relative abundance of more than 0.5%. Predominant species included other abundant coastal and estuarine taxa, including the shore crab Carcinus maenas and the amphipod Corophium volutator. Jacobs' selectivity index estimates based on DNA extracted from both shrimp stomachs and sediment samples were used to assess the shrimp's trophic niche indicating a generalist diet, dominated by crustaceans, polychaetes and fish. Spatial variation in diet composition, at regional and local scales, confirmed the highly flexible nature of this trophic opportunist. Furthermore, the detection of a prevalent, possibly endoparasitic fungus (Purpureocillium lilacinum) in the shrimp's stomach demonstrates the wide range of questions that can be addressed using metabarcoding, towards a more robust reconstruction of ecological networks. PMID- 30276913 TI - Phosphazene Bases as Organocatalysts for Ring-Opening Polymerization of Cyclic Esters. AB - Over the past several years, organocatalyzed polymerization reactions have attracted considerable attention, and these efforts have led to major advances. A large number of organic compounds have been proven active for the polymerization of a large variety of monomers. In particular, phosphazene bases (PBs) are a family of extremely strong, non-nucleophilic, and uncharged auxiliary bases, and have shown their remarkable potential as organocatalysts for the ring-opening polymerization (ROP) of cyclic monomers. By deprotonation of weak acids or in combination with lithium cation, PBs significantly enhance the nucleophilicity of the initiator/chain-end, thus allowing fast and usually controlled anionic polymerization. In this feature article, the recent advances in phosphazene catalyzed ROP of cyclic esters are summarized. This review is divided into three sections, including general features, design and synthesis, and catalytic applications. It aims to provide a critical analysis of PB-mediated ROP systems and a useful guide for the further design of organocatalysts applied to polymer synthesis. An outlook is given at the end. PMID- 30276914 TI - The relationship between socioeconomic status and white matter microstructure in pre-reading children: A longitudinal investigation. AB - Reading is a learned skill crucial for educational attainment. Children from families of lower socioeconomic status (SES) tend to have poorer reading performance and this gap widens across years of schooling. Reading relies on the orchestration of multiple neural systems integrated via specific white-matter pathways, but there is limited understanding about whether these pathways relate differentially to reading performance depending on SES background. Kindergarten white-matter FA and second-grade reading outcomes were investigated in an SES diverse sample of 125 children. The three left-hemisphere white-matter tracts most associated with reading, and their right-hemisphere homologs, were examined: arcuate fasciculus (AF), superior longitudinal fasciculus (SLF), and inferior longitudinal fasciculus (ILF). There was a significant and positive association between SES and fractional anisotropy (FA) in the bilateral ILF in kindergarten. SES moderated the association between kindergarten ILF and second grade reading performance, such that it was positive in lower-SES children, but not significant in higher-SES children. These results have implications for understanding the role of the environment in the development of the neural pathways that support reading. PMID- 30276915 TI - Psychosocial distress and utilization of professional psychological care in cancer patients: An observational study in National Comprehensive Cancer Centers (CCCs) in Germany. AB - OBJECTIVE: The study aimed to assess cancer patients' use of psychological care and its correlates in a large sample of cancer patients in Comprehensive Cancer Centers (CCCs) in Germany. METHODS: In a multicenter study in Germany, cancer patients with various diagnoses were evaluated for self-reported use of psychological support. We measured psychological distress, depression and anxiety, quality of life, and social support with standardized questionnaires and analyzed its association with the utilization of psychological care using multivariable logistic regression. This paper focuses on a cross-sectional analysis of the data assessed during inpatient care. RESULTS: Three thousand fifty-four (50%) of hospitalized patients were asked for participation, and n = 1632 (53.6%) participated. We were able to analyze n = 1,398 (45.9%) patients. Three hundred ninety-seven (28.4%) of the sample utilized psychological support. Users of psychological care were significantly younger than nonusers (odds ratio [OR]: 0.967, P < 0.001) and were more often female (OR: 1.878, P < 0.001), whereas educational level was not associated with the use of psychological care. In the multivariable analysis, effects on the use of psychological care were observed for Hospital Anxiety and Depression Scale (HADS) anxiety (OR: 1.106, P = 0.001) and both subscales of the 12-item Short Form Health Survey (SF-12) quality of life measure (mental, OR: 0.97, P = 0.002; physical, OR: 0.97, P = 0.002). CONCLUSION: Psychological distress and anxiety are higher, and quality of life is lower in users of psychological care in comparison with nonusers during inpatient cancer treatment. Although psychooncological services should be provided to all patients who need them, special efforts should be made to reach populations that report low utilization. PMID- 30276916 TI - Effects of high-intensity functional circuit training on motor function and sport motivation in healthy, inactive adults. AB - PURPOSE: A small share of the world's population meets current physical activity guidelines, which recommend regular engagement in endurance, strength, and neuromotor exercise. As lack of time represents a major cause of inactivity, multidimensional training methods with short durations may provide a promising alternative to classical, volume-oriented approaches focusing on one biomotor ability. This trial examined the effects of a high-intensity functional circuit training (HIFCT) on motor performance and exercise motivation in untrained adults. METHODS: Thirty-three inactive participants were randomly allocated to two groups exercising for six weeks. The intervention group (HIFCT, n = 20) 3*/week performed functional whole-body exercises in a circuit. Each 15-minute workout included repetitive 20s all-out bouts with 10s breaks. In the comparison group (moderate aerobic exercise, MAE, n = 13), the participants walked 3*/week for 50 minutes at moderate intensity. Measured motor outcomes were cycling endurance capacity (respiratory threshold, maximum workload), maximum strength (leg and chest press), postural control (force plate), and jump capacity (counter movement jump, single leg hop for distance); exercise motivation was assessed using the self-concordance index. RESULTS: In comparison with MAE, HIFCT enhanced maximum leg strength (between-group difference of relative pre- to post-changes of 5.0%), shoulder strength (7.6%), and endurance workload (5.0%; P < 0.05), while increasing motivation to exercise (+5.5 points, P < 0.05). No between-group differences occurred for postural control and jump capacity (P > 0.05). CONCLUSION: Despite considerably shorter training duration, HIFCT enhances motor function and motivation to exercise more effectively than MAE. Further research should investigate the long-term adherence to the program and its effectiveness in other settings. PMID- 30276918 TI - SunSmart news? Traditional media coverage of sun protection issues during springtime in New Zealand. AB - ISSUES ADDRESSED: Cutaneous melanomas and keratinocyte carcinomas (nonmelanoma skin cancer) are highly prevalent in New Zealand (NZ), making skin cancer a priority area for cancer control. Spring is an important time for encouraging sun safety, due to ultraviolet radiation (UVR) levels becoming hazardous. The news media have a potential to play an important role in reminding people and emphasising the importance of sun-safety. This study aimed to describe how the traditional NZ media portrayed sun-safety and skin cancer in spring news stories. METHODS: A media monitoring company collated stories related to cancer during spring 2016. These were reviewed for inclusion and content was coded according to the cancer type described. Stories focused on skin cancer and sun protection issues were coded according to the position on the cancer control continuum. RESULTS: Skin cancer and sun-safety represented 3.6% (n = 110) of all cancer stories published. Stories mainly related to primary prevention (72%), early detection (37%) and survivorship (27%). The main risk factors identified included sun exposure (49%) and tanning (25%). CONCLUSIONS: Traditional media coverage of skin cancer remains relatively low during springtime. It is heartening to see that most stories included prevention information. SO WHAT?: Given the impact of skin cancer in NZ, and the importance of springtime as a period for behaviour change to reduce risk, there is considerable scope for increased media coverage and advocacy. Further research could usefully analyse media trends throughout the year and within specific media platforms, both traditional and new, in order to further disseminate information to the NZ public. PMID- 30276917 TI - A novel group of spindle cell tumors defined by S100 and CD34 co-expression shows recurrent fusions involving RAF1, BRAF, and NTRK1/2 genes. AB - Tumors characterized by co-expression of S100 and CD34, in the absence of SOX10, remain difficult to classify. Triggered by a few index cases with monomorphic cytomorphology and distinctive stromal and perivascular hyalinization, immunopositivity for S100 and CD34, and RAF1 and NTRK1 fusions, the authors undertook a systematic review of tumors with similar features. Most of the cases selected were previously diagnosed as low-grade malignant peripheral nerve sheath tumors, while others were deemed unclassified. The tumors were studied with targeted RNA sequencing and/or FISH. A total of 25 cases (15 adults and 10 children) with kinase fusions were identified, including 8 cases involving RAF1, 2 BRAF, 14 NTRK1, and 1 NTRK2 gene rearrangements. Most tumors showed a monomorphic spindle cell proliferation with stromal and perivascular keloidal collagen, in a patternless architecture, with only occasional scattered pleomorphic or multinucleated cells. Most cases showed low cellularity, a low mitotic count, and absence of necrosis. Although a subset showed overlap with lipofibromatosis-like neural tumors, the study group showed distinctive hyalinization and overt malignant features, such as highly cellular fascicular growth and primitive appearance. All tumors showed co-expression of S100 and CD34, ranging from focal to diffuse. SOX10 was negative in all cases. NTRK1 immunohistochemistry showed high levels of expression in all tumors with NTRK1 gene rearrangements. H3K27me3 expression performed in a subset of cases was retained. These findings together with the recurrent gene fusions in RAF1, BRAF, and NTRK1/2 kinases suggest a distinct molecular tumor subtype with consistent S100 and CD34 immunoreactivity. PMID- 30276920 TI - Cognitive neuroscience can support public health approaches to minimise the harm of 'losses disguised as wins' in multiline slot machines. AB - Video slot machines are associated with both accelerated transition into problematic forms of gambling, as well as psychosocial harm above and beyond other forms of gambling. A growing body of evidence is uncovering how key design features of multiline slot machines produce an inflated experience of reward, despite the fact that these features offer no overall financial benefit to the player. A pernicious example of this are 'losses disguised as wins' (LDWs), which occur when simultaneous bets placed on multiple lines result in a winning combination that returns an amount greater than zero, but less the total wager. These events are usually accompanied by the same celebratory sounds and animations that accompany true wins. We argue that LDWs may leverage neuropsychological phenomena that underlie reinforcement learning and contribute to extended or repetitive use and gambling-related harm. While other characteristics of slot machine gambling have been examined by cognitive neuroscientists, this feature has not yet received attention. Neuroscientific methods can be used to assess the impact of LDWs on the human reward system, to assess the claim that these events are a reinforcing and contributing factor in the development of harmful play. Positive findings would provide further persuasive evidence in support of strategies to minimise gambling harm through the regulation of machine design. PMID- 30276919 TI - Renal perfusion parameters measured by contrast-enhanced ultrasound in healthy dogs demonstrate a wide range of variability in the long-term. AB - Contrast-enhanced ultrasound may be helpful for detecting early renal microvascular damage and dysfunction in dogs. However, before this noninvasive imaging method can be tested as an early-stage screening tool in clinical patients, an improved understanding of long-term variation in healthy animals is needed. In this prospective, secondary, longitudinal, serial measurements study, variability of contrast-enhanced ultrasound renal perfusion parameters was described for eight healthy dogs, using seven time points and a period of 83 weeks. Dogs were sedated with butorphanol (0.4 mg/kg), and contrast-enhanced ultrasound of each kidney was performed after an intravenous bolus injection of a microbubble contrast agent (0.04 mL/kg). Time-intensity curves were created from regions-of-interest drawn in the renal cortex and medulla. Intensity-related parameters representing blood volume and time-related parameters representing blood velocity were determined. A random-effects model using restricted maximum likelihood was used to estimate variance components. Within-dog coefficient of variation was defined as the ratio of the standard deviation over the mean. Time related parameters such as time-to-peak, rise and fall time had lowest within-dog variability. Intensity-related parameters such as peak enhancement, wash-in and wash-out area under the curve, total area under the curve, and wash-in and washout rates had high within-dog variability (coefficient of variation > 45%). Authors therefore recommend the use of time-related parameters for future studies of renal perfusion. Within-dog variability for bilateral kidney measurements was extremely low, therefore contrast-enhanced ultrasound may be particularly useful for detecting unilateral changes in renal perfusion. Future studies are needed to compare contrast-enhanced ultrasound findings in healthy dogs versus dogs with renal disease. PMID- 30276921 TI - Inhibitory effects of ascorbic acid toward snake venom metalloproteinase (SVMP) from Indian Echis carinatus venom: Insights from molecular modeling and binding studies. AB - Classical antivenom therapy is unable to shield complications of viper bite and has limitations such as anaphylaxis and serum sickness. Snake venom metalloproteinases are responsible for local tissue damage and hemorrhage at the bitten site in viper envenomation, and this has led to a persistent search for metalloproteinase inhibitors. Here, we report the inhibitory effects of ascorbic acid against metalloproteinase from Echis carinatus venom both in-silico and in vitro. Ascorbic acid effectively inhibited the proteolytic activity of E. carinatus venom in a dose-dependent manner. Interaction studies of ascorbic acid with purified ecarin using isothermal titration calorimetry showed favorable binding energy and energetics. The molecular docking of ascorbic acid with ecarin revealed important interactions with residues at the active site pocket of ecarin. It was observed that the ligand behaves as a chelating inhibitor. Thus, the backbone structural scaffold of ascorbic acid can find potential use as building blocks in designing drug-like molecules for viper bite management. PMID- 30276922 TI - Orexin-mediated restoration of hippocampal synaptic potentiation in mice with established cocaine-conditioned place preference. AB - Orexins (also called hypocretins) are implicated in reward and addiction, but little is known about their role(s) in the association between hippocampal synaptic plasticity and drug preference. Previously, we found that exogenous orexin via OX1 and OX2 receptors can impair low frequency stimulation-induced depotentiation, i.e. restoring potentiation of excitatory synaptic transmission (re-potentiation) in mouse hippocampal slices. Here, we found this re potentiation in hippocampal slices from mice that had acquired conditioned place preference (CPP) to cocaine. Both 10 and 20 mg/kg of cocaine induced similar magnitudes of CPP in mice and re-potentiation in their hippocampal slices, but differed in their susceptibility to TCS1102, a dual (OX1 and OX2 ) orexin receptor antagonist. TCS1102 significantly attenuated CPP and hippocampal re potentiation induced by cocaine at 10 mg/kg but not at 20 mg/kg. Nonetheless, SCH23390, an antagonist of dopamine D1-like receptors (D1-likeRs), inhibited the effects induced by both doses of cocaine. SKF38393, a D1-likeR-selective agonist, also induced hippocampal re-potentiation in vitro. Interestingly, this effect was attenuated by TCS1102. Conversely, SCH23390 prevented orexin A-induced hippocampal re-potentiation. These results suggest that endogenous orexins are released in mice during cocaine-CPP acquisition, which sustains potentiated hippocampal transmission via OX1 /OX2 receptors and may contribute to the addiction memory of cocaine. This effect of endogenous orexins, however, may be substituted by dopamine that may dominate hippocampal re-potentiation and CPP via D1-likeRs when the reinforcing effect of cocaine is high. PMID- 30276923 TI - A field ecologist's adventures in the virtual world: using simulations to design data collection for complex models. AB - Field data collection can be expensive, time consuming, and difficult; insightful research requires statistical analyses supported by sufficient data. Pilot studies and power analysis provide guidance on sampling design but can be challenging to perform, as ecologists increasingly collect multiple types of data over different scales. Despite a growing simulation literature, it remains unclear how to appropriately design data collection for many complex projects. Approaches that seek to achieve realism in decision-making contexts, such as management strategy evaluation and virtual ecologist simulations, can help. For a relatively complex analysis, we develop and demonstrate a flexible simulation approach that informs what data are needed and how long those data will take to collect, under realistic fieldwork constraints. We simulated data collection and analysis under different constraint scenarios that varied in deterministic (field trip length, travel, and measurement times) and stochastic (species detection and occupancy rates and inclement weather) features. In our case study, we fit plant height data to a multispecies, three-parameter, nonlinear growth model. We tested how the simulated data sets, based on the varying constraint scenarios, affected the model fit (parameter bias, uncertainty, and capture rate). Species prevalence in the field exerted a stronger influence on the data sets and downstream model performance than deterministic aspects such as travel times. When species detection and occupancy were not considered, the field time needed to collect an adequate data set was underestimated by 40%. Simulations can assist in refining fieldwork design, estimating field costs, and incorporating uncertainties into project planning. We argue that combining data collection, analysis, and decision making processes in a flexible virtual setting can help address many of the decisions that field ecologists face when designing field-based research. PMID- 30276924 TI - Molecular Basis for the Mechanical Response of Sulfa Drug Crystals. AB - Appreciating the nanomechanical response in crystalline materials demands one to comprehend on the elastic and plastic deformation mechanisms occurring in the vicinity of the nanoindenter tip, in terms of the underlying crystal structures. We combined the nanoindentation data with structural and computational inputs to derive a molecular-level understanding of the nanomechanical response in eight prototypical sulfa drug molecular crystals. The magnitude of the modulus, E, is strongly connected to the non-covalent bond features-the bond strength, the relative orientation with the measured crystal facet as well as their disposition in the crystal lattice. Additional features deciphered from the current studies are: i) robust synthons well-isolated by weak and dispersive interactions reduce the material stiffness; in contrast, interweaving of interactions with diverse energetics fortifies the crystal packing; ii) mere observation of layered structures with orthogonal distribution of strong and weak interactions is a prerequisite but inadequate to attain higher plasticity, and iii) interlocked molecular arrangements prevent long-range sliding of molecular planes and hence lead to enhanced E. Within a broader perspective, the observations are remarkable in deriving a molecular basis of the mechanical properties of crystalline solids, which can be exploited through crystal engineering for the purposeful design of materials with specific properties. PMID- 30276925 TI - Direct Differentiation of Stereoisomers of Ezetimibe/Ambrisentan/Atorvastatin and their Mechanism Study by Electrospray Ionization Quadurupole Time-of-Flight Mass Spectrometry. AB - A mass spectrometric method is introduced for rapid and accurate chiral quantification by examining a trimeric metal complex into which a chiral reference is incorporated with the analyte. Several metal ions (CuII, NiII, MgII, MnII, CoII, ZnII) were selected as the central metal ion, and chiral drugs ezetimibe (EZM) and ambrisentan (AMB) were used as the reference to each other for isomeric differentiation by using electrospray ionization quadrupole time-of flight mass spectrometry. Doubly charged trimeric cluster ions instead of the singly charged clusters were applied in this study. Kinetic method (KM) and chiral recognition (CR) method were used for construction of a calibration curve for chiral quantitation. The results from the two methods were found to be complementary to each other, which improved quantitative analysis of stereoisomers for EZM. Furthermore, we have successfully used S-AMB as reference for the chiral differentiation of enantiomeric atorvastatin (ATO), which is frequently combined with EZM as a co-drug. Experimental results showed that the binary mixture of EZM and ATO enantiomers can be determined simultaneously without prior separation steps. The direct measurement of chiral purity within 5% was demonstrated. This mass spectrometric method represents an effective alternative to commonly used chromatographic techniques as means of chiral purity determination and is of potential use in rapid screening experiments. PMID- 30276926 TI - A comparative study: visual rating scores and the voxel-based specific regional analysis system for Alzheimer's disease on magnetic resonance imaging among subjects with Alzheimer's disease, mild cognitive impairment, and normal cognition. AB - AIM: Hippocampal atrophy shown on magnetic resonance imaging can differentiate Alzheimer's disease (AD) patients from subjects with normal cognition (NC). Simplified automated methods that use volumetric analysis, such as as the voxel based specific regional analysis system for AD, have become widely used in Japan. However, the diagnostic value of the voxel-based specific regional analysis system compared with visual rating scores for clinical diagnosis is unclear. METHODS: Study participants consisted of 37 AD patients, 29 mild cognitive impairment (MCI) patients, and 21 NC subjects. All participants underwent neuropsychological testing and magnetic resonance imaging. The imaging was scored visually for regional brain atrophy by two raters based on a newly developed visual rating score. The voxel-based specific regional analysis system for AD scores were calculated with the analysis system's advanced software. We analyzed whether these scores aid in discriminating among AD, MCI, and NC. RESULTS: The AD group had significantly different visual rating scores, regional analysis scores, and all neuropsychological test scores than the NC group. The AD group had significantly different visual rating scores than the MCI group, and a significant difference was observed between the MCI and NC groups on regional analysis scores. Both the visual rating and regional analysis scores showed equivalent correlations with the neuropsychological test scores. CONCLUSIONS: Both the visual rating and regional analysis scores are clinically useful tools for differentiating among AD, MCI, and NC. PMID- 30276927 TI - Montelukast abrogates prednisolone-induced hepatic injury in rats: Modulation of mitochondrial dysfunction, oxidative/nitrosative stress, and apoptosis. AB - The aim of this study was to investigate the protective effect of montelukast (MTK) against prednisolone-induced hepatic injury in rats. Twenty-eight male albino rats were categorized into four equal groups. Group I served as the control group; group II: rats orally received prednisolone (5 mg.kg-1 .d-1 ) for 30 days; groups III and IV: rats orally received MTK at 10 and 20 mg.kg-1 .d-1 , respectively, simultaneously with prednisolone for 30 days. Serum liver enzymes, hepatic mitochondrial function, oxidative/nitrosative stress, and inflammatory and apoptotic markers were evaluated, and the results were confirmed by histopathological examination. MTK showed significant hepatic protection evidenced by alleviated histological lesion and improvement of mitochondrial function, oxidative/nitrosative stress, and inflammatory and apoptotic changes induced by prednisolone, with more profound protection in higher MTK dose (20 mg.kg-1 ). In view of these findings, we can conclude that MTK may have hepatoprotective potential, beyond its therapeutic value for asthmatic patients during their course of corticosteroid therapy. PMID- 30276928 TI - Monitoring population levels of physical activity and sedentary time in Norway across the lifespan. AB - PURPOSE: The pandemic of physical inactivity is recognized globally but there is a scarcity of studies employing valid and reliable assessment methods of physical activity (PA) across the lifespan. The purpose of this study is to provide a comprehensive description of objectively measured PA, sedentary time, and prevalence of meeting PA recommendations, in a population-based sample of Norwegian children, adolescents and adults. METHODS: Children and adolescents (6, 9 and 15-year-olds) were surveyed in 2011, and adults and older people (20-85 year-olds) were surveyed in 2014/15, including more than 8000 individuals. Anthropometric data were measured in children and adolescents and self-reported in the adult sample. PA was assessed by ActiGraph accelerometers for seven consecutive days, and PA indices include total PA (counts per minute), intensity specific PA, and adherence to PA recommendations. RESULTS: Six-year-olds are 21% and 70% more active than 9- and 15-year-olds, respectively (P < 0.001). Nine-year olds are 40% more active compared to 15-year-olds (P < 0.001). Moving from adolescence (15-year-olds) into adulthood (20-65 years) yields a further reduction in total PA by 18%. Among six-, nine- and 15-year olds, 90%, 77%, and 48% meet the current PA recommendations, respectively, while adherence among adults and older people are 33% and 31%, respectively. Overweight and obese individuals had lower odds of meeting PA recommendations. CONCLUSIONS: The results from the Norwegian surveillance system indicate a strong association between age and indices of physical activity. The vast majority of Norwegian adults do not meet the PA recommendations and public health action are needed to increase PA in Norway. PMID- 30276929 TI - Clinical management of the status of atypical endometrial cells using the descriptive reporting format for endometrial cytology. AB - OBJECTIVE: We aimed to develop and reinforce a clinical management regimen for atypical endometrial cell (ATEC) categories within the descriptive reporting format for endometrial cytology. METHODS: Between January 2013 and December 2014, 215 samples, for which histological examination was performed immediately or within 3 months after cytology, were cytologically diagnosed as ATEC. For these samples, the medical records were retrospectively reviewed to identify risk factors for malignancy. RESULTS: Among 152 samples diagnosed as ATEC, of undetermined significance, 19 (12.5%) were malignant. In the younger group (age <55 years), the chi2 values of body mass index (BMI) >=25 kg/m2 (5.85), gravidity (5.64) and parity (5.15) were relatively high, suggesting that these were risk factors for malignancy. Of the nulligravida patients, those with BMI >=25 kg/m2 , 28% were diagnosed with malignant disease. In the older group (>=55 years), endometrial thickening (6.84), atypical genital bleeding (6.43) and BMI >=25 kg/m2 (3.79) were found to be risk factors for malignancy. Of the patients with endometrial thickening and atypical genital bleeding, 67% were diagnosed with malignant disease. Among 63 samples diagnosed as ATEC, cannot exclude atypical endometrial hyperplasia or more, 35 (55.6%) samples were positive for malignancy. CONCLUSIONS: High-risk patients diagnosed with ATEC, of undetermined significance were identified. Endometrial biopsy should be considered for nulligravida patients aged <55 years with a BMI >=25 kg/m2 . PMID- 30276930 TI - Abnormal esophageal motility during a solid test meal in systemic sclerosis detection even in very early disease and association with disease progression. AB - OBJECTIVE: This study assessed whether high-resolution manometry (HRM) with a test meal can detect clinically relevant, abnormal motility already in very early systemic sclerosis (SSc) and whether this finding is associated with subsequent disease progression. METHODS: This prospective, longitudinal cohort study recruited 68 consecutive SSc patients (group #1: 32 established disease (ACR, American College of Rheumatology /EULAR, The European League against Rheumatism 2013 and ACR 1980 criteria fulfilled); group #2: 24 early disease (only ACR/EULAR 2013 fulfilled); group #3: 12 very early disease (clinical expert diagnosis of SSc) and 72 healthy controls. HRM evaluated esophageal motility for water swallows and a solid test meal. RESULTS: Systemic sclerosis patients had less frequent effective esophageal contractions during the test meal compared to healthy controls even in very early disease (0.15, 1.0, 2.1 per minute for groups #1, #2, and #3, vs 2.5 per minute in health; P < 0.001, P < 0.001, and P < 0.0085, respectively). Ineffective motility at HRM was associated with a higher modified Rodnan skin score at baseline. Moreover, at mean 18 (10-31) months of follow-up, the presence of ineffective motility at baseline was associated with progression of skin disease (P = 0.01). Cox proportional hazard regression analysis identified hypotensive peristalsis in the test meal (<15% effective solid swallows) and low distal contractile integral (DCI; <400 mm Hg.cm.s) as predictors for skin aggravation, but not for new organ involvement. CONCLUSION: Ineffective motility during a test meal is present already in patients with very early SSc. Findings on HRM studies are associated with disease severity at baseline, and low percentage of effective swallows in test meal and low mean DCI are both predictors of skin progression during follow-up. PMID- 30276931 TI - Cytisine versus varenicline for smoking cessation for Maori (the indigenous people of New Zealand) and their extended family: protocol for a randomized non inferiority trial. AB - BACKGROUND AND AIMS: Cytisine, a nicotinic acetylcholine receptor partial agonist (like varenicline) found in some plants, is a low-cost, effective smoking cessation medication that may appeal to Maori [the indigenous people of New Zealand (NZ)]. The RAUORA trial aims to determine the effectiveness, safety and cost-effectiveness of cytisine (Tabex(r) ) versus varenicline (Champix(r) ) for smoking cessation in Maori and the whanau (extended family) of Maori. DESIGN: Pragmatic, community-based, open-label randomized non-inferiority trial. SETTING: Lakes District Health Board region, NZ. PARTICIPANTS: Daily smokers (n = 2140) who self-identify as Maori or whanau of Maori, and are: aged >= 18 years, motivated to quit smoking in the next 2 weeks, eligible for subsidized varenicline, able to provide verbal consent and have daily access to a mobile phone/internet. Recruitment uses multi-media advertising. INTERVENTION AND COMPARATOR: Participants are randomized (1 : 1 ratio) to receive a prescription for 12 weeks of cytisine tablets [following the manufacturer's dosing regimen for 25 days, then one 1.5-mg tablet every 6 hours (two per day) until 12 weeks] or varenicline tablets (following the manufacturer's dosing regimen). Both groups receive brief stop-smoking advice from the prescribing doctor and withdrawal orientated behavioural support via community-based stop-smoking counselling services (frequency, duration and mode of delivery tailored for participants) or a research assistant (six weekly 10-15-minute calls). Participants are advised to reduce their smoking over the first 4 days of treatment, with day 5 as their designated quit-date. MEASUREMENTS: The primary outcome is carbon monoxide verified continuous abstinence at 6 months post-quit date. Secondary outcomes at 1, 3, 6 and 12 months post-quit date include: self-reported continuous abstinence, 7-day point prevalence abstinence, cigarettes per day, time to (re)lapse, adverse events, treatment adherence/compliance, treatment acceptability, nicotine withdrawal/urge to smoke and health-care utilization/health-related quality of life. COMMENTS: This trial compares cytisine and varenicline when used by the indigenous people of NZ and their extended family for smoking cessation.

PMID- 30276933 TI - Neural correlates of facial emotion processing in infancy. AB - In the present study we examined the neural correlates of facial emotion processing in the first year of life using ERP measures and cortical source analysis. EEG data were collected cross-sectionally from 5- (N = 49), 7- (N = 50), and 12-month-old (N = 51) infants while they were viewing images of angry, fearful, and happy faces. The N290 component was found to be larger in amplitude in response to fearful and happy than angry faces in all posterior clusters and showed largest response to fear than the other two emotions only over the right occipital area. The P400 and Nc components were found to be larger in amplitude in response to angry than happy and fearful faces over central and frontal scalp. Cortical source analysis of the N290 component revealed greater cortical activation in the right fusiform face area in response to fearful faces. This effect started to emerge at 5 months and became well established at 7 months, but it disappeared at 12 months. The P400 and Nc components were primarily localized to the PCC/Precuneus where heightened responses to angry faces were observed. The current results suggest the detection of a fearful face in infants' brain can happen shortly (~200-290 ms) after the stimulus onset, and this process may rely on the face network and develop substantially between 5 to 7 months of age. The current findings also suggest the differential processing of angry faces occurred later in the P400/Nc time window, which recruits the PCC/Precuneus and is associated with the allocation of infants' attention. PMID- 30276934 TI - The ontogeny of intent-based normative judgments. AB - When evaluating norm transgressions, children begin to show some sensitivity to the agent's intentionality around preschool age. However, the specific developmental trajectories of different forms of such intent-based judgments and their cognitive underpinnings are still largely unclear. The current studies, therefore, systematically investigated the development of intent-based normative judgments as a function of two crucial factors: (a) the type of the agent's mental state underlying a normative transgression, and (b) the type of norm transgressed (moral versus conventional). In Study 1, 5- and 7-year-old children as well as adults were presented with vignettes in which an agent transgressed either a moral or a conventional norm. Crucially, she did so either intentionally, accidentally (not intentionally at all) or unknowingly (intentionally, yet based on a false belief regarding the outcome). The results revealed two asymmetries in children's intent-based judgments. First, all age groups showed greater sensitivity to mental state information for moral compared to conventional transgressions. Second, children's (but not adults') normative judgments were more sensitive to the agent's intention than to her belief. Two subsequent studies investigated this asymmetry in children more closely and found evidence that it is based on performance factors: children are able in principle to take into account an agent's false belief in much the same way as her intentions, yet do not make belief-based judgments in many existing tasks (like that of Study 1) due to their inferential complexity. Taken together, these findings contribute to a more systematic understanding of the development of intent-based normative judgment. PMID- 30276935 TI - Neural correlates of time distortion in a preaction period. AB - An intention to move distorts the perception of time. For example, a visual stimulus presented during the preparation of manual movements is perceived longer than actual. Although neural mechanisms underlying this action-induced time distortion have been unclear, here we propose a new model in which the distortion is caused by a sensory-motor interaction mediated by alpha rhythm. It is generally known that viewing a stimulus induces a reduction in amplitude of occipital 10-Hz wave ("alpha-blocking"). Preparing manual movements are also known to reduce alpha power in the motor cortex ("mu-suppression"). When human participants prepared movements while viewing a stimulus, we found that those two types of classical alpha suppression interacted in the third (time-processing) region in the brain, inducing a prominent decrease in alpha power in the supplementary motor cortex (SMA). Interestingly, this alpha suppression in the SMA occurred in an asymmetric manner (such that troughs of alpha rhythm was more strongly suppressed than peaks), which can produce a gradual increase (slow shift of baseline) in neural activity. Since the neural processing in the SMA encodes a subjective time length for a sensory event, the increased activity in this region (by the asymmetric alpha suppression) would cause an overestimation of elapsed time, resulting in the action-induced time distortion. Those results showed a unique role of alpha wave enabling communications across distant (visual, motor, and time-processing) regions in the brain and further suggested a new type of sensory-motor interaction based on neural desynchronization (rather than synchronization). PMID- 30276936 TI - Bradyrhizobium and Pseudomonas strains obtained from coal-mining areas nodulate and promote the growth of Calopogonium muconoides plants used in the reclamation of degraded areas. AB - AIMS: The objective of this work was to isolate and characterize indigenous rhizobia from coal-mining areas able to efficiently nodulate and fix nitrogen in association with Calopogonium mucunoides (calopo). METHODS AND RESULTS: Isolation, authentication and morphological, biochemical and molecular characterization of the autochthonous rhizobia were performed and their symbiotic efficiency (SE) evaluated. Efficient rhizobial isolates suitable for the inoculation of calopo in coal-mining regions were obtained. A total of 30 isolates were obtained after nodulation authentication, of which five presented high SE with plant-growth promoting traits such as indole-3-acetic acid production, phosphate solubilization and biofilm formation. These isolates were identified as belonging to Bradyrhizobium, Pseudomonas and Rhizobium. CONCLUSIONS: Bradyrhizobium sp. A2-10 and Pseudomonas sp. A6-05 were able to promote calopo plant growth using soil obtained from coal-mining degraded areas, thus indicating their potential as inoculants aiming at land reclamation. SIGNIFICANCE AND IMPACT OF THE STUDY: To our knowledge, this is the first report of Pseudomonas nodule formation in calopo. Furthermore, the results demonstrated that autochthonous rhizobia obtained from degraded soils presented high SE in calopo and possess a wide range of plant-growth promoting traits. Ultimately, they may all contribute to an increased leguminous plant growth under stress conditions. The selected rhizobia strains may be used as inoculants and present a valuable role in the development of strategies aiming to recover coal-mining degraded areas. Bacterial inoculants would greatly reduce the use of often harmful nitrogen fertilizers vastly employed in revegetation programmes of degraded areas.

AB - Primary effusion lymphoma (PEL) is a rare mature B-cell non-Hodgkin's lymphoma arising in body cavities and presenting with effusions. It has been described predominantly in patients with impaired immunity from the acquired immunodeficiency syndrome and is associated with the Human Herpesvirus-8 (HHV-8). Seldom has PEL been diagnosed in persons negative for the human immunodeficiency virus (HIV), and in such cases it has occurred primarily in the setting of posttransplant immunosuppression. We report an instructive case of a Caribbean American HIV-negative orthotopic heart transplant recipient with a history of HHV 8-associated Kaposi's sarcoma who developed HHV-8 viremia and PEL of the pleural space early in the posttransplant course. This case highlights the importance of considering PEL in the differential diagnosis of a new pleural effusion in a transplant recipient at risk for HHV-8-associated disease. PMID- 30276938 TI - N6 -Methyladenosine-Sensitive RNA-Cleaving Deoxyribozymes. AB - Deoxyribozymes are synthetic enzymes made of DNA that can catalyze the cleavage or formation of phosphodiester bonds and are useful tools for RNA biochemistry. Herein, we report new RNA-cleaving deoxyribozymes to interrogate the methylation status of target RNAs, thereby providing an alternative method for the biochemical validation of RNA methylation sites containing N6 -methyladenosine, which is the most wide-spread and extensively investigated natural RNA modification. The developed deoxyribozymes are sensitive to the presence of N6 methyladenosine in RNA near the cleavage site. One class of these DNA enzymes shows faster cleavage of methylated RNA, while others are strongly inhibited by the modified nucleotide. The general applicability of the new deoxyribozymes is demonstrated for several examples of natural RNA sequences, including a lncRNA and a set of C/D box snoRNAs, which have been suggested to contain m6 A as a regulatory element that influences RNA folding and protein binding. PMID- 30276939 TI - Cognitive activity in a sitting position is protectively associated with cognitive impairment among older adults. AB - AIM: Previous studies have obtained inconsistent results regarding the association between sedentary behavior and cognitive impairment. The present study aimed to examine the association between cognitive activity in a sitting position (CAS) and cognitive impairment among older adults. METHODS: Community dwelling older adults, from Obu or Nagoya in Japan, participated in a survey in 2013. A total of 5300 participants (mean age 75.0 +/- 5.1 years; women 52.9%) met the criteria for the present study. We assessed the frequency and variety of CAS composed of six activities, including reading books or newspapers, writing a diary or letters, solving crossword puzzles, playing board games, using a computer and maintaining housekeeping records. The frequency of engagement in CAS was one or more time(s)/week. The variety of CAS was assessed by the number of engagements in CAS. Cognitive impairment was defined by two or more tests at least 1.5 standard deviations below the reference threshold in four neuropsychological tests. Logistic regression analysis was carried out to examine the associations between the frequency and variety of CAS and cognitive impairment, adjusted for covariates. RESULTS: The proportion of participants engaging in each CAS varied from 12.3% (playing board games) to 93.6% (reading books or newspaper). After adjustment, five CAS were significantly associated with cognitive impairment (OR 0.33-0.65, all P < 0.001). The variety of CAS was significantly associated with the reduced OR of cognitive impairment (OR 0.61, 95% confidence interval 0.55-0.68). CONCLUSIONS: Almost every CAS and a greater variety of CAS are associated with cognitive impairment among older people. Geriatr Gerontol Int 2018; **: **-**. PMID- 30276940 TI - A review on biocide reduced susceptibility due to plasmid-borne antiseptic resistant genes-special notes on pharmaceutical environmental isolates. AB - Biocides (antiseptics and disinfectants) are widely used in hospitals and pharmaceutical industries for contamination control. The emergence of reduced susceptibility to biocides is the major concern and this is caused by various factors, among which plasmid-mediated resistance is common. Many publications describe the antibiotic resistance and mechanisms in a clinical setting. However, there are only limited studies available worldwide addressing the molecular mechanisms of biocide resistance in the pharmaceutical sector. In addition, there is a considerable lack of scientific reports regarding minimum inhibitory concentration (MIC) values of typical biocides against pharmaceutical cleanroom environmental isolates. This review analyses the plasmid-mediated resistance in typical pharmaceutical micro-organisms and prevalence of biocide-resistant genes among common clinical and pharmaceutical isolates. This review discusses the MIC values of biocides in pharmaceutical environmental isolates, indicating the importance of the correlation between the presence or absence of biocide resistant genes and reduced susceptibility of MIC values. This review recommends that pharmaceutical organizations adopt policies and test methodologies to examine the MICs of common cleanroom biocides against the most common types of cleanroom environmental isolates. PMID- 30276941 TI - Impact of probiotic Lactobacillus sp. on autochthonous lactobacilli in weaned piglets. AB - AIMS: This study aimed to determine whether host-adapted lactobacilli exhibit superior survival during intestinal transit relative to nomadic and free-living organisms, and to characterize the impact of probiotic lactobacilli on autochthonous lactobacilli. METHODS AND RESULTS: Mixed cultures of Lactobacillus casei K9-1 and Lactobacillus fermentum K9-2, or reutericyclin producing Lactobacillus reuteri and its isogenic mutant were fed to piglets as freeze-dried culture, or as part of fermented feed. Lactobacilli in digesta and faecal samples were quantified by strain-specific quantitative PCR (qPCR), high-resolution melting curve qPCR, and high-throughput sequencing of 16S rRNA gene sequence tags. The abundance of the host adapted L. reuteri in digesta and faeces was higher (P < 0.05) when compared to L. casei or L. fermentum. Feed fermentation or chemical acidification of feed reduced (P < 0.05) cell counts of Lactobacillus salivarius in colonic digesta. The reutericyclin producing L. reuteri TMW1.656 transiently reduced (P < 0.05) the faecal abundance of lactobacilli. However, the overall impact of probiotic intervention on autochthonous lactobacilli was minor. CONCLUSIONS: The vertebrate host-adapted L. reuteri survives better during intestinal transit of piglets compared to L. casei and L. fermentum. SIGNIFICANCE AND IMPACT OF THE STUDY: Ecology and lifestyle of Lactobacillus strains may be suitable criteria for selection of probiotic strains for use in swine production. PMID- 30276942 TI - Limits to species richness in terrestrial communities. AB - Are communities limited by biotic interactions, or are they random draws from regional species pools? One way to tell is to compare total species counts in geographic regions to average counts in ecological samples falling within those regions. If species richness is limited regionally, then the relationship should be curvilinear even in a log-log space. Global sets of samples including trees and 10 groups of animals are analysed to test this hypothesis. Most relationships are indeed curvilinear. To explain these patterns, a simple model is proposed that invokes biotic interaction-limited speciation or immigration rates combined with extinction or extirpation rates that fall as the number of occupied patches increases. Local and regional richness come into balance as the rates trade off, causing global richness to also be limited. Surprisingly, however, the data for trees break the pattern, suggesting that the great adaptive radiation of seed plants may still be unfolding.

AB - Reported is a tandem palladium-catalyzed Heck/regioselective C(sp3 )-H activation reaction for the divergent synthesis of spiro- and fused-cyclopropanated indolines from N-methallylated 2-bromoarylamides. The regioselectivity of the C-H bond activation in the sigma-alkylPdII intermediate is controlled by the solvent used. DFT calculations suggest that the polarity of solvent molecules could influence the transition-state energy, leading to a bifurcation of the C-H bond activation in the sigma-alkylPdII intermediate. PMID- 30276945 TI - Conformational Dynamics in the Core of Human Y145Stop Prion Protein Amyloid Probed by Relaxation Dispersion NMR. AB - Microsecond to millisecond timescale backbone dynamics of the amyloid core residues in Y145Stop human prion protein (PrP) fibrils were investigated by using 15 N rotating frame (R1rho ) relaxation dispersion solid-state nuclear magnetic resonance spectroscopy over a wide range of spin-lock fields. Numerical simulations enabled the experimental relaxation dispersion profiles for most of the fibril core residues to be modelled by using a two-state exchange process with a common exchange rate of 1000 s-1 , corresponding to protein backbone motion on the timescale of 1 ms, and an excited-state population of 2 %. We also found that the relaxation dispersion profiles for several amino acids positioned near the edges of the most structured regions of the amyloid core were better modelled by assuming somewhat higher excited-state populations (~5-15 %) and faster exchange rate constants, corresponding to protein backbone motions on the timescale of ~100-300 MUs. The slow backbone dynamics of the core residues were evaluated in the context of the structural model of human Y145Stop PrP amyloid. PMID- 30276946 TI - Decreased perfusion of the posterior cingulate gyri shown by a cingulate island score is a possible marker of vulnerability to behavioural and psychological symptoms of Alzheimer's disease: a pilot study. AB - BACKGROUND: The cingulate island score (CIScore), which indicates the Z-score ratio of the posterior cingulate gyri to the medial occipital area, has been shown to be useful for differentiating dementia with Lewy bodies from Alzheimer's disease (AD). Our aim was to investigate associations between the clinical symptoms of AD and the CIScore as an index of the relative decrease in perfusion of the posterior cingulate gyri that occurs in the early stages of AD. METHODS: Seventeen patients with early-stage AD and 13 patients with amnesic mild cognitive impairment were examined. Z-score maps of technetium-99m ethyl cysteinate dimer single-photon emission computed tomography images acquired from the patients were converted, and the CIScore was determined by using the easy Z score imaging system. The relationships between the CIScore and clinical symptom scores were tested. RESULTS: A significant correlation was identified between the CIScore and the Neuropsychiatric Inventory Questionnaire score. No significant correlations were identified between the CIScore and other measures of cognitive function. Based on a CIScore of 0.39, we correctly differentiated patients with and without behavioural and psychological symptoms of dementia (BPSD), with a sensitivity of 72.2% and specificity of 75.0%. DISCUSSION: Using technetium-99m ethyl cysteinate dimer single-photon emission computed tomography, we observed that decreased posterior cingulate gyri perfusion, relative to the medial occipital area, in prodromal and early AD was closely associated with behavioural and psychological symptoms of dementia. Therefore, our findings suggest that CIScore is not only useful for discriminating dementia with Lewy bodies from AD, but it can also be clinically used as a specific indicator of the vulnerability to behavioural and psychological symptoms of dementia in the early stages of AD. PMID- 30276947 TI - Raman spectroscopy for the preoperative diagnosis of thyroid cancer and its subtypes: An in vitro proof-of-concept study. AB - OBJECTIVE: In 2016, there were an estimated 56 870 new cases of thyroid cancer (TC) in the USA. Fine needle aspiration cytology (FNAC) is the most safe, accurate and cost-effective method for the initial investigation of thyroid nodules. FNAC is limited by the inability to diagnose malignancy in follicular patterned lesions accurately and, as a result, 20%-30% of cases under investigation for TC are classified as cytologically indeterminate, illustrating a problem with current FNAC procedure. Raman spectroscopy has shown promising results for the detection of many cancers; however, to date there has been no report on the performance of Raman spectroscopy on thyroid cytological samples. The aim of this study was to examine whether Raman spectroscopy could be used to correctly classify cell lines representing benign thyroid cells and various subtypes of TC. METHODS: A benign thyroid cell line and seven TC cell lines were prepared as ThinPrep(r) cytology slides and analysed with Raman spectroscopy. Principal components analysis and linear discriminant analysis were implemented to develop effective diagnostic algorithms for classification of Raman spectra of different TC subtypes. RESULTS: The spectral differences separating benign and TC cell lines were assigned to differences in the composition of nucleic acids, lipids, carbohydrates and protein in the benign and cancer cells. Good sensitivities (74%-85%), specificities (65%-93%) and diagnostic accuracies (71% 88%) were achieved for the identification of TC. CONCLUSION: These findings suggest that Raman spectroscopy has potential for preoperative TC diagnosis on FNAC samples.

AB - The carbon-carbon and carbon-heteroatom bond formation reactions are considered as a fundamental tool in synthetic organic chemistry. They have been effectively utilized in the synthesis of medicinally significant molecules, agrochemicals and valuable compounds in material sciences. This has been primarily enabled by highly efficient protocols arising from divergent mechanistic pathways. In this personal account, we aim to discuss some recent advances in carbon-carbon or carbon-heteroatom bond formation reactions to which our group has actively contributed. More specifically, this record focuses on the use of unsaturated carbon compounds for the construction of C-C and C-X bonds. PMID- 30276949 TI - Mannich-type Reactions of Cyclic Nitrones: Effective Methods for the Enantioselective Synthesis of Piperidine-containing Alkaloids. AB - Even though there are dozens of biologically active 2-substituted and 2,6 disubstituted piperidines, only a limited number of approaches exist for their synthesis. Herein is described two Mannich-type additions to nitrones, one using beta-ketoacids under catalyst-free conditions and another using methyl ketones in the presence of chiral thioureas, which can generate a broad array of such 2 substituted materials, as well as other ring variants, in the form of beta-N hydroxy-aminoketones. Both processes have broad scope, with the latter providing products with high enantioselectivity (up to 98 %). The combination of these methods, along with other critical steps, has enabled 8-step total syntheses of the 2,6-disubstituted piperidine alkaloids (-)-lobeline and (-)-sedinone.

AB - AIMS: To study the prevalence, risk factors, role of serum biomarkers for diagnosis and impact of invasive fungal infections (IFIs) in patients with acute on-chronic liver failure (ACLF). METHODS: An analysis of IFI in patients with ACLF (EASL criteria) was conducted retrospectively. The diagnosis of IFI in clinically suspected patients was based on EORTC/MSG criteria. The demographical, clinical, laboratory details and outcomes were analysed. RESULTS: Out of 264 patients with ACLF, 54 (20.4%) patients with suspicion of IFI were evaluated and IFI was diagnosed in 39 (14.7%). Invasive candidiasis was documented in 25 (64.1%) and invasive aspergillosis in 14 (35.8%). The most common source of infection was respiratory (n = 13) followed by renal (n = 7) and spontaneous fungal peritonitis (n = 6). On univariate analysis, diabetes mellitus, hemodialysis, prior antibiotic use, cerebral and respiratory organ failures, Chronic Liver Failure Consortium (CLIF-OF and CLIF-C ACLF) scores were predictors for development of IFI (P < 0.05). On multivariate analysis, hemodialysis and prior antibiotics use predicted the development of IFI (P < 0.05). Non-survivors were more likely to have IFI (P = 0.029), high CLIF-OF and CLIF-C ACLF scores (P < 0.001; for both) and higher 1,3-beta D Glucan (BDG) levels (P = 0.009). The sensitivity, specificity, and AUROC of BDG (80 pg/mL) and Galactomannan index (GMI [0.5]) for diagnosing IFI were 97.4%, 60%, 0.770% and 43.6%, 100%, 0.745 respectively. CONCLUSIONS: Invasive fungal infections constitutes an important cause of mortality in ACLF patients. BDG and GMI can be useful markers to guide antifungal therapy in patients at high risk for IFI. PMID- 30276953 TI - Congenital lumbar hernia-A feature of diabetic embryopathy? AB - Congenital lumbar hernia is a rare anomaly consisting of protrusion of abdominal organs or extraperitoneal tissue through a defect in the lateral abdominal wall. The majority of affected patients have additional anomalies in a pattern described as the lumbocostovertebral syndrome. We report four patients born to mothers with poorly controlled diabetes with congenital lumbar hernia. All patients exhibited features of lumbocostovertebral syndrome with lumbar hernia, multiple vertebral segmentation anomalies in the lower thoracic and/or upper lumbar spine, rib anomalies, and unilateral renal agenesis. Additional anomalies present in the patients included preaxial hallucal polydactyly, abnormal situs, and sacral dysgenesis, anomalies known to be associated with diabetic embryopathy. At least 11 other patients have been previously reported with the lumbocostovertebral syndrome in the setting of maternal diabetes. We suggest that congenital lumbar hernia and the lumbocostovertebral syndrome are related to diabetic embryopathy.

In this context, the first and second generation solar cells commercially available in market for more than decades however limitations in production cost and large-scale applications insist to generate inexpensive materials for fabrication. Thereby, organic materials based solar cells explored and emerging as third generation solar cells which possess flexibility, low cost and large-scale applications. For example, organic photovoltaics, dye sensitized solar cells and perovskite (organic-inorganic) solar cells (PSCs) are considered third generation solar cells wherein PSCs reached the record power conversion efficiency (PCE ~23 %) and durability assists great advantages for commercialization in near future. Moreover, we reported various global renowned companies involved producing the modules and materials for three generation solar cells, hence, majority of companies considered commercialization of perovskite based solar cells assist low cost photovoltaics to meet the current energy necessities and environmental safety.

AB - Heteroatom-doped porous carbon derived from biomass have recently received increasing attention due to their unique properties such as high electrical conductivity, large specific surface area, high porosity, and easy availability, which are appealing materials for versatile applications in catalysis, energy, separation and adsorption, and life sciences as well. On the basis of our previous work in this field, we summarized in this account our recent progress on design, synthesis of metal (e. g., Pd, Co) nanoparticles supported heteroatom doped hierarchical porous carbon material derived from bamboo shoots and their applications for important organic transformations, including chemoselective semihydrogenation of alkynes, hydrosilylation of alkynes, cascade synthesis of benzofurans from terminal alkynes and iodophenols, selective hydrogenation of functionalized nitroarenes to form anilines, imines, and formamides. Finally, the current state and future challenges in this field are discussed. We hope this account could shed light on the rational design of novel non-noble metal based heterogeneous catalysts derived from biomass for efficient and sustainable organic transformations. PMID- 30276957 TI - Symptom severity, symptom interference and use of complementary and alternative medicine among survivors of colorectal and breast cancer after curative treatment in Taiwan. AB - This study compared symptom severity, symptom interference and use of complementary and alternative medicine (CAM) between cancer survivors after curative treatment and individuals who did not have cancer. Factors associated with CAM use among cancer survivors were examined. A cross-sectional survey was conducted of 146 cancer survivors (77 breast and 69 colorectal cancer survivors who had completed conventional treatment 1-5 years previously and were cancer free) from a hospital's cancer registration system (survivor group), and 161 healthy individuals without cancer (comparison group). The two groups were frequency-matched for sex and age. Findings indicated higher use of CAM in the survivor group (54.1%) than the comparison group (36.6%). There were no significant differences in overall symptom severity and interference between the two groups. Multivariate logistic regression showed that prior use of CAM (OR = 5.14, 95% CI: 2.34-10.69) and higher symptom interference (OR = 1.04, 95% CI: 1.001-1.08) were positively related to CAM use in the survivor group. The survivors did not have higher symptom severity and symptom interference with daily life, but were more likely to use CAM than the comparison group. Medical staff should discuss symptom interference and use of CAM with cancer survivors to guide them in the appropriate use of CAM. PMID- 30276955 TI - Replacement of microglia in the aged brain reverses cognitive, synaptic, and neuronal deficits in mice. AB - Microglia, the resident immune cell of the brain, can be eliminated via pharmacological inhibition of the colony-stimulating factor 1 receptor (CSF1R). Withdrawal of CSF1R inhibition then stimulates microglial repopulation, effectively replacing the microglial compartment. In the aged brain, microglia take on a "primed" phenotype and studies indicate that this coincides with age related cognitive decline. Here, we investigated the effects of replacing the aged microglial compartment with new microglia using CSF1R inhibitor-induced microglial repopulation. With 28 days of repopulation, replacement of resident microglia in aged mice (24 months) improved spatial memory and restored physical microglial tissue characteristics (cell densities and morphologies) to those found in young adult animals (4 months). However, inflammation-related gene expression was not broadly altered with repopulation nor the response to immune challenges. Instead, microglial repopulation resulted in a reversal of age related changes in neuronal gene expression, including expression of genes associated with actin cytoskeleton remodeling and synaptogenesis. Age-related changes in hippocampal neuronal complexity were reversed with both microglial elimination and repopulation, while microglial elimination increased both neurogenesis and dendritic spine densities. These changes were accompanied by a full rescue of age-induced deficits in long-term potentiation with microglial repopulation. Thus, several key aspects of the aged brain can be reversed by acute noninvasive replacement of microglia.

PMID- 30276959 TI - Intention-to-treat analysis of liver transplantation for hepatocellular carcinoma: The impact of pre-existing diabetes mellitus. AB - BACKGROUND & AIMS: Diabetes mellitus is known to negatively impact the outcome of liver transplant; however, data are scarce regarding risk of waitlist dropout and tumour recurrence in patients with hepatocellular carcinoma. We examined the impact of diabetes mellitus on the outcomes of candidates with hepatocellular carcinoma on an intention-to-treat basis. METHODS: Our study included 15 776 candidates with hepatocellular carcinoma diagnosis on the Scientific Registry of Transplant Recipients database from 2008 to 2015 to evaluate the risk of waitlist dropout, hepatocellular carcinoma recurrence and overall survival. RESULTS: There were more patients dropped out from the waiting list owing to patient disease deterioration or tumour progression in the diabetes mellitus group (15.1% vs 13.7%, P = 0.024). The mean waiting time was similar in the two groups (233 days vs 230 days, P = 0.631). The recurrence rate was higher in the diabetes mellitus group (9.0% vs 6.2%, P < 0.001); however, the mean time to recurrence in the two groups was similar (23.7 months vs 22.6 months, P = 0.371). Diabetes mellitus, tumours exceeding Milan criteria, and AFP >400 ng/mL were independent predictive factors for recurrence. On an intention-to-treat basis, diabetes mellitus was also an independent poor prognostic factor for overall survival; however, the overall survival was comparable with tumours beyond Milan criteria. CONCLUSIONS: Diabetes mellitus was associated with poor survival outcomes and an increased risk of waitlist dropout and tumour recurrence rates in hepatocellular carcinoma patients. Those patients should be paid more attention to cardiovascular and oncological examination when determining waitlist and post-transplant surveillance strategies. PMID- 30276961 TI - Applicability of Sepsis-3 criteria and quick Sequential Organ Failure Assessment in patients with cirrhosis hospitalised for bacterial infections. AB - BACKGROUND & AIMS: An algorithm including Sepsis-3 criteria and quick Sequential Organ Failure Assessment (qSOFA) was recently proposed to predict severity of infection in cirrhosis. However, its applicability among patients without a baseline SOFA available for Sepsis-3 definition is unknown. We sought to investigate the applicability and prognostic value of qSOFA and Sepsis-3 criteria in patients with cirrhosis hospitalised for bacterial infections, without pre hospitalisation SOFA. METHODS: In this cohort study, 164 patients were followed up to 30 days. Data collection, including the prognostic models, was performed at admission and at day-3. RESULTS: All patients fulfilled Sepsis-3 criteria (admission SOFA >= 2) and, therefore, admission Sepsis-3 was not included in further analysis. Admission qSOFA was an independent predictor of survival (HR = 2.271, P = 0.015). For patients initially classified as high risk by qSOFA, Chronic Liver Failure - Sequential Organ Failure Assessment (CLIF-SOFA) was the only prognostic predictor. Among patients initially classified as low risk by qSOFA, the following parameters evaluated at day-3 were independent predictors of survival: qSOFA, acute-on-chronic liver failure, and Child-Pugh classification. Although not independently related to survival, Sepsis-3 criteria at day-3 was associated with lower 30-day survival in Kaplan-Meier analysis (66% vs 85%, P = 0.008). However, prognosis was better predicted by day-3 qSOFA, with 30-day Kaplan-Meier survival probability of 88% when qSOFA < 2 and 24% among those with qSOFA >= 2. CONCLUSION: Sepsis-3 criteria evaluated at admission are very limited in infected patients with cirrhosis without baseline SOFA. qSOFA was independently related to survival and appears to be a valuable tool for determining severity of infection and to follow patients initially classified as low risk. PMID- 30276962 TI - Multicenter study of mortality in achondroplasia. AB - Sudden death and higher mortality are recognized in achondroplasia, with acute brainstem compression, a common cause of mortality in children <4 years and cardiovascular deaths being more prevalent in adults. Although, changes in clinical management have improved survival, mortality is still higher than in the general population. The aim of this multicenter clinic-based study was to assess the rate and causes of mortality in patients seen in clinic since 1986. Information was ascertained for achondroplasia patients clinically assessed in four skeletal dysplasia clinics. Data was sent to the National Death Index to identify vital status and cause of death. Standardized mortality rates (SMR) were calculated based on U.S. populations from 1975, 1995, and 2000. Eight hundred fifty-five patients were identified, contributing 12,117 person-years and a total of 12 deaths. One case died in infancy. In the 1-4 year age group, which had the highest age-adjusted SMR, three out of five deaths were because of cerebrovascular/cardiovascular events. Half the deaths in ages 5 through 24 were because of accidental events, including motor vehicle accidents. Decreased mortality in children with achondroplasia was noted, particularly in younger age groups. This improvement in childhood survival is outpaced by improved survival in the general population. Causes of death in these patients have shifted over the last 30 years, with fewer sudden death and deaths because of pneumonia or hydrocephalus countered by more cardiovascular or cerebrovascular and accidental deaths. Clinicians should be aware of the apparent increased risk of vehicular accidents and counsel patients accordingly. PMID- 30276963 TI - Women travelling without men, and their health care needs. PMID- 30276964 TI - Microvascular circulatory dysregulation driven in part by cystathionine gamma lyase: A new paradigm for cardiovascular compromise in the preterm newborn. AB - OBJECTIVE: H2 S may explain the dysregulation of microvascular tone associated with poor outcome following preterm birth. In adult vasculature, H2 S is predominantly produced by CSE. We hypothesized that vascular CSE activity contributes to microvascular tone regulation during circulatory transition. METHODS: Preterm (GA62) and full-term (GA69) guinea pig fetuses and neonates were studied. Microvascular blood flow was assessed by laser Doppler flowmetry. Thiosulfate, primary urinary metabolite of H2 S, was determined by high performance liquid chromatography. Real-time H2 S production was assessed using a microrespiration system in fetal and postnatal (10, 24 hours) skin and heart samples. CSE contribution was investigated by inhibition via propargylglycine. RESULTS: In preterm animals, postnatal H2 S production capacity in peripheral vasculature increased significantly and was significantly reduced by the inhibition of CSE. Urinary thiosulfate correlated with both microvascular blood flow and capacity of the vasculature to produce H2 S. H2 S produced via CSE did not correlate directly with microvascular blood flow. CONCLUSIONS: In preterm neonates, H2 S production increases during fetal-to-neonatal transition and CSE contribution to total H2 S increases postnatally. CSE-dependent mechanisms may therefore underpin the increase in H2 S production over the first 72 hours of life in preterm human neonates, associated with both central and peripheral cardiovascular instability. PMID- 30276965 TI - In vitro and in vivo antischistosomal activities of chalcones. AB - In this study, we evaluated the in vitro and in vivo schistosomicidal activities of chalcones against Schistosoma mansoni worms. In vitro assays revealed that chalcones 1 and 3 were the most active compounds, without affecting significantly mammalian cells. Confocal laser scanning microscopy and scanning electron microscopy studies revealed reduction on the numbers of tubercles and morphological alterations in the tegument of S. mansoni worms after in vitro incubation with chalcones 1 and 3. In a mouse model of schistosomiasis, the oral treatment (400 mg/kg) with chalcone 1 or 3 significantly caused a total worm burden reduction in mice. Chalcone 1 showed significant inhibition of the S. mansoni ATP diphosphohydrolase activity, which was corroborated by molecular docking studies. Results suggested that chalcones could be explored as lead compounds with antischistosomal properties. PMID- 30276966 TI - Genetic analyses of differences between solid and nonsolid predominant lung adenocarcinomas. AB - BACKGROUND: Solid predominant lung adenocarcinomas (LUAD) have distinct histopathological and clinical characteristics compared with nonsolid subtypes. A comprehensive comparison of altered genes found in solid and nonsolid subtypes has not previously been performed. In this study, we analyzed differences in gene expression, genetic mutations, and DNA methylation to better understand the risk factors for these two subtypes of LUAD. METHODS: Differentially expressed genes (DEGs) and differentially mutated genes (DMGs) were analyzed from RNA-seq data downloaded from The Cancer Genome Atlas (TCGA) and Broad Institute database. To understand the functional significance of molecular changes, we examined the DEGs and DMGs with Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis. RESULTS: A total of 184 patients in the TCGA cohort and 140 patients in the Broad Institute cohort were included in this study. We identified 75 DEGs, of which 15 were upregulated and 56 downregulated in the solid group relative to the nonsolid group. The DEGs were mainly involved in the regulation of water and fluid transport. We discovered 38 significantly differentially expressed genes that overlapped in the two groups. The DMGs were mainly enriched for pathways involved in cell-cell adhesion, cell adhesion, biological adhesion, and hemophilic cell adhesion. We additionally discovered nine significantly methylated genes between solid and nonsolid LUAD. CONCLUSIONS: Our study identified distinct DEGs, DMGs, and methylation genes for solid and nonsolid LUAD subtypes. These findings improve our understanding of the different carcinogenesis mechanisms in LUAD and will help to develop new therapeutic strategies. PMID- 30276967 TI - Use of beta-blocker is associated with lower mortality in patients with coronary artery disease with or without COPD. AB - INTRODUCTION: Beta-blockers are indicated for secondary prevention of coronary artery disease (CAD). However, in patients with co-morbidity of chronic obstructive pulmonary disease (COPD) an underuse of beta-blocker has been reported. MATERIALS AND METHODS: Prescription and demographic data and information on hospital discharge diagnoses from 13 Austrian health insurance funds for the years 2006-2007 were analyzed. The primary end point was all-cause mortality of patients with CAD with or without COPD and its association with use of beta-blockers. RESULTS: In 2006 and 2007, 65717 patients (37% female, 63% male) were discharged with a diagnosis of CAD. Among these patients, 46% had a co diagnosis of COPD, 24% had diabetes, and 75% received beta-blockers. Use of beta blockers was comparable in CAD patients with COPD and without COPD with 77% and 74%, respectively. Thousand eight hundred seventy-two (8.1%) and 1473 (5.6%) patients with and without COPD, who used beta-blockers died within months in 2006 and 2007. Thousand five hundred fifty-three (22.0%) and 1862 (22.2%) of patients with and without COPD and without beta-blockers died during the corresponding time period. DISCUSSION: Use of beta-blockers was similar in patients with CAD with or without co-diagnosis of COPD. However, mortality of beta-blocker users was markedly lower than that of nonusers in patients with CAD with or without COPD. PMID- 30276968 TI - Bitterless guaifenesin prodrugs-design, synthesis, characterization, in vitro kinetics, and bitterness studies. AB - A respected number of drugs suffer from bitter taste which results in patient incompliance. With the aim of solving the bitterness of guaifenesin, dimethyl maleate, maleate, glutarate, succinate, and dimethyl succinate prodrugs were designed and synthesized. Molecular orbital methods were utilized for the design of the ester prodrugs. The density functional theory (DFT) calculations revealed that the hydrolysis efficiency of the synthesized prodrugs is significantly sensitive to the pattern of substitution on C=C bond and distance between the nucleophile and the electrophile. The hydrolysis of the prodrugs was largely affected by the pH of the medium. The experimental t1/2 for the hydrolysis of guaifenesin dimaleate ester prodrugs in 1N HCl was the least and for guaifenesin dimethyl succinate was the highest. Functional heterologous expression of TAS2R14, a broadly tuned bitter taste receptor responding to guaifenesin, and experiments using these prodrugs revealed that, while some of the prodrugs still activated the receptor similarly or even stronger than the parent substance, succinate derivatization resulted in the complete loss of receptor responses. The predicted binding modes of guaifenesin and its prodrugs to the TAS2R14 homology model suggest that the decreased activity of the succinate derivatives may be caused by a clash with Phe247. PMID- 30276970 TI - Disaccharide-Based Anionic Amphiphiles as Potent Inhibitors of Lipopolysaccharide Induced Inflammation. AB - Despite significant advances made in the last decade in the understanding of molecular mechanisms of sepsis and in the development of clinically relevant therapies, sepsis remains the leading cause of mortality in intensive care units with increasing incidence worldwide. Toll-like receptor 4 (TLR4)-a transmembrane pattern-recognition receptor responsible for propagating the immediate immune response to Gram-negative bacterial infection-plays a central role in the pathogenesis of sepsis and chronic inflammation-related disorders. TLR4 is complexed with the lipopolysaccharide (LPS)-sensing protein myeloid differentiation-2 (MD-2) which represents a preferred target for establishing new anti-inflammatory treatment strategies. Herein we report the development, facile synthesis, and biological evaluation of novel disaccharide-based TLR4?MD-2 antagonists with potent anti-endotoxic activity at micromolar concentrations. A series of synthetic anionic glycolipids entailing amide-linked beta-ketoacyl lipid residues was prepared in a straightforward manner by using a single orthogonally protected nonreducing diglucosamine scaffold. Suppression of the LPS induced release of interleukin-6 and tumor necrosis factor was monitored and confirmed in human immune cells (MNC and THP1) and mouse macrophages. Structure activity relationship studies and molecular dynamics simulations revealed the structural basis for the high-affinity interaction between anionic glycolipids and MD-2, and highlighted two compounds as leads for the development of potential anti-inflammatory therapeutics. PMID- 30276972 TI - Contributions of regulated transcription and mRNA decay to the dynamics of gene expression. AB - Organisms have acquired sophisticated regulatory networks that control gene expression in response to cellular perturbations. Understanding of the mechanisms underlying the coordinated changes in gene expression in response to external and internal stimuli is a fundamental issue in biology. Recent advances in high throughput technologies have enabled the measurement of diverse biological information, including gene expression levels, kinetics of gene expression, and interactions among gene expression regulatory molecules. By coupling these technologies with quantitative modeling, we can now uncover the biological roles and mechanisms of gene regulation at the system level. This review consists of two parts. First, we focus on the methods using uridine analogs that measure synthesis and decay rates of RNAs, which demonstrate how cells dynamically change the regulation of gene expression in response to both internal and external cues. Second, we discuss the underlying mechanisms of these changes in kinetics, including the functions of transcription factors and RNA-binding proteins. Overall, this review will help to clarify a system-level view of gene expression programs in cells.

PMID- 30276971 TI - First data from a parent-reported registry of 81 individuals with Coffin-Siris syndrome: Natural history and management recommendations. AB - Coffin-Siris syndrome (CSS; MIM 135900) is a multisystem congenital anomaly syndrome caused by mutations in the genes in the Brg-1 associated factors (BAF) complex. Classically, individuals with CSS have been described with hypo- or aplasia of the fifth digit nails or phalanges (hence the term "fifth digit syndrome"). Other physical features seen include growth restriction, coarse facial features, hypertrichosis or hirsutism, sparse scalp hair, dental anomalies, and other organ-system abnormalities. Varying degrees of developmental and intellectual delay are universal. To date, approximately 200 individuals have been described in the literature. With the advent of large-scale genetic testing such as whole-exome sequencing is becoming more available, more individuals are being found to have mutations in this pathway, and the phenotypic spectrum appears to be broadening. We report here a large cohort of 81 individuals with the diagnosis of CSS from the first parent-reported CSS/BAF complex registry in an effort to describe this variation among individuals, the natural history of the syndrome, and draw some gene-phenotype correlations. We propose that changes in the BAF complex may represent a spectrum of disorders, including both ARID1B related nonsyndromic intellectual disability (ARID1B-ID) and CSS with classic physical features. In addition, we offer surveillance and management recommendations based on the medical issues encountered in this cohort to help guide physicians and patients' families. PMID- 30276969 TI - Evaluation of the prognostic value of surgery and postoperative radiotherapy for patients with thymic neuroendocrine tumors: A propensity-matched study based on the SEER database. AB - BACKGROUND: The prognostic value of surgery and postoperative radiotherapy (PORT) for primary thymic neuroendocrine tumors (TNETs) was estimated using the SEER database. METHODS: This retrospective study used SEER data of TNET patients between 1998 and 2015. Propensity score matching (PSM) was performed according to whether surgery was performed. The prognostic effects on overall survival (OS) and cancer-specific survival (CSS) were evaluated using multivariate Cox regression. RESULTS: A total of 3947 patients were included: 293 (7.4%) TNET, 2788 (70.6%) thymoma, and 866 (21.9%) thymic carcinoma. Compared to other subtypes, TNET patients were younger, included a larger proportion of men, had a well or moderately differentiated histological grade, higher disease stage at diagnosis, and were more likely to have regional lymph node metastasis. The median OS and CSS for TNET were 82.9 (95% confidence interval 74.3-91.4) and 101.9 (95% confidence interval 91.9-111.8) months, respectively, significantly shorter than for thymomas. In the matched cohort of TNET patients, multivariate analysis of OS and CSS revealed a significantly poorer prognosis in the non surgery group (P < 0.001). Compared to total/radical resection, TNET patients who underwent debulking resection had significantly inferior outcomes (P < 0.05). Postoperative radiotherapy favorably impacted OS and CSS in Masaoka-Koga stage III-IV TNET patients; this OS impact was also observed in stage IIB patients. CONCLUSION: TNETs are extremely rare with relatively dismal outcomes. This analysis revealed the role of complete surgical resection and the favorable effect of postoperative radiotherapy in specific TNET subgroups. PMID- 30276973 TI - Human omental adipose-derived stem cells from donors with different body mass index had similar effects on proliferation and migration of endometrial cancer cells in vitro. AB - AIM: This study aimed to confirm whether human omental adipose-derived stem cells (O-ASC) from donors with varying body mass index (BMI, calculated in kg/m2 ) exert different effects on proliferation and migration of endometrial cancer (EC) cells. METHODS: Omental adipose-derived stem cells were isolated from the omental adipose tissues of eight patients who were diagnosed with EC aged from 35 to 56 years. According to the patients' BMI, the O-ASC was divided into two groups: obesity group (BMI >= 30) and normal group (18.5 < BMI <= 24.9). A broad spectrum cytokine antibody array was used to measure 62 paracrine cytokines secreted by all the O-ASC. MTS assays, direct and indirect co-culture assays were used to assess the effects of O-ASC on proliferation and migration of Hec-1A (estrogen receptor-/progesterone receptor-) and Ishikawa (estrogen receptor+/progesterone receptor+) EC cells. RESULTS: Eight samples of O-ASC were successfully isolated including four samples in obesity group and four in normal group. All the O-ASC displayed typical characteristics of mesenchymal stem cells and possessed similar secretory functions as 26 cytokines were identified in condition medium of O-ASC based on cytokine antibody array. The proliferation of Ishikawa cells was gently stimulated by O-ASC from the two groups (P < 0.05) whereas without any effects on Hec-1A cells. Both horizontal and vertical migrations of EC cells were promoted by O-ASC (P < 0.01). However, there were no statistical differences between the two groups. CONCLUSION: Human O-ASC could influence the proliferation and migration of EC cells in vitro but the effects were not modified by donors' BMI.

PMID- 30276974 TI - Adjuvant radiotherapy, chemotherapy or surgery alone for high-risk histological node negative esophageal squamous cell carcinoma: Protocol for a multicenter prospective randomized controlled trial. AB - Histologically node negative esophageal squamous cell carcinoma (pN0 ESCC) after radical resection still carries a significant risk of recurrence, especially in high-risk patients. Our previous study showed that the risk of recurrence was associated with tumor location and cell differentiation, as well as the presence of lymphovascular invasion. Most recurrence occurs within two years after surgery. There is still a lack of knowledge on the risks or potential benefits of postoperative adjuvant therapies for high-risk pN0 ESCC patients. This study was designed to evaluate the efficacy and toxicity of adjuvant therapies after radical surgery in high-risk patients with pN0 ESCC. This study is a multicenter, prospective, controlled randomized trial, which will compare the differences between either adjuvant chemotherapy or adjuvant radiotherapy and surgery alone for high-risk pN0 ESCC. Patients in group A will receive three cycles of adjuvant chemotherapy with paclitaxel and cisplatin, patients in group B will receive adjuvant radiotherapy with intensity-modulated radiation of 50 Gy, and patients in group C (the control) will receive surgery alone. The primary endpoint is three-year disease-free survival. Secondary endpoints include toxicity of adjuvant therapies and five-year overall survival. One hundred and sixty-two patients in each group are required and a total of 486 patients will finally be enrolled into the study. This will be the first randomized trial to investigate the necessity or potential benefit of postoperative adjuvant therapies for high risk pN0 ESCC patients.

PMID- 30276977 TI - Six-week pretreatment with growth hormone improves clinical outcomes of poor ovarian responders undergoing in vitro fertilization treatment: A self-controlled clinical study. AB - AIM: The purpose was to explore whether the 6 weeks of growth hormone (GH) pretreatment could increase the live birth rate of poor ovarian responders (POR). METHODS: This self-controlled, retrospective study was performed among 380 POR who had GH adjuvant (GH+) at a university-affiliated hospital in Guangzhou, China, from October 2010 to April 2016. Growth hormone was injected daily beginning with the previous menstruation and maintained until ovum pickup, for approximately 6 weeks. Clinical variables between the GH+ cycle and the other GH free (GH-) cycle of each patient were compared. Both cycles were conducted with a similar conventional control ovarian hyperstimulation protocol for in vitro fertilization treatment. One to one case-control matching was performed to adjust essential confounding factors between GH+ cycles and GH- cycles. RESULTS: GH pretreatment improved embryo quality (1.14 +/- 1.50 vs 0.11 +/- 0.48, P < 0.05) and decreased miscarriage (18.8% vs 80.0%, P < 0.05) significantly, resulting in an increase in the live birth rate (23.5% vs 3.9%, P < 0.05). The oocyte utilization rate in GH+ cycles was remarkably improved, even with older patients and more failed previous attempts. Significant improvement in embryo quality was shown by an increased number of good-quality embryos and improved oocyte utilization rate after matching. CONCLUSIONS: The longer term use of low-dose GH administration for 6 weeks could be beneficial for the utilization of oocytes and for finally increasing the live birth rates of POR. PMID- 30276978 TI - Half-sandwich Iridium(III) Benzimidazole-Appended Imidazolium-Based N heterocyclic Carbene Complexes and Antitumor Application. AB - A series of half-sandwich iridium(III) benzimidazole-appended imidazolium-based N heterocyclic carbene (NHC) antitumor complexes [(eta5 -Cpx )Ir(C^N)Cl]Cl, where Cpx is pentamethylcyclopentadienyl (Cp*) or its biphenyl derivative (Cpxbiph ) and C^N is a NHC chelating ligand, were successfully synthesized and characterized. The IrIII complexes showed potential antitumor activity against A549 cells, at most three times more potent than cis-platin under the same conditions. Complexes could bind to BSA by a static quenching mode, catalyzing the change of NADH to NAD+ and inducing the production of reactive oxygen species (maximum turnover number, 9.8), which play an important role in regulating cell apoptosis. Confocal microscopy showed that the complexes could specifically target lysosomes in cells with a Pearson's co-localization coefficient 0.76 and 0.72 after 1 h and 6 h, respectively, followed an energy-dependent cellular uptake mechanism and damaged the integrity of lysosomes. At the same time, complexes caused a marked loss of mitochondrial membrane potential. PMID- 30276980 TI - Strong responses from weakly interacting species. AB - The impact of species loss from competitive communities partly depends on how populations of the surviving species respond. Predicting the response should be straightforward using models that describe population growth as a function of competitor densities; but these models require accurate estimates of interaction strengths. Here, we quantified how well we could predict responses to competitor removal in a community of annual plants, using a combination of observation and experiment. It was straightforward to fit models to multi-species communities, which passed standard diagnostic tests and provided apparently sensible estimates of interaction strengths. However, the models consistently underpredicted the response to competitor removal, by a factor of at least 50%. We argue that this poor predictive ability is likely to be general in plant communities due to 'the ghost of competition present' that confines species to parts of the environment in which they compete best.

AB - Immunotherapy has revolutionized the treatment of non-small cell lung cancer; however, its role in the treatment response of lung brain metastasis is unknown. Understanding immunotherapy activity in the central nervous system is important in order to avoid additional toxicity, such as that associated with the use of cerebral radiotherapy. We present two cases with clinical and radiological progression with increases in size and perilesional edema of brain lesions after treatment with a combination of ipilimumab and nivolumab. The increasing use of immunotherapy in lung cancer requires increased knowledge of new patterns of radiological response, such as pseudoprogression. PMID- 30276981 TI - Creatinine excretion in consecutive urine samples after controlled ingestion of water. AB - Highly diluted urine is among the most commonly observed factors affecting the validity of urine testing for drug abuse. A minimum creatinine concentration of 20 mg/dL urine has been proposed as a marker for dilution of a urine sample. This study investigates the effect of water consumption on creatinine concentration, as well as its effect on specific gravity and osmolality. In this study, 22 subjects (17 women and 5 men) were included to determine the influence of sex and weight on the impact of excessive water consumption on these markers of urine dilution. The subjects consumed 0.5 L, 1.0 L, and 1.5 L of water, respectively, within 15 minutes. The mean minimum creatinine concentrations (Jaffe reaction) for the void 2 hours after fluid intake were 60.4 mg/dL, 15.8 mg/dL, and 10.9 mg/dL for the respective ingested volumes of water. Mean creatinine concentrations excreted by men were significantly higher than those excreted by women. Participants with a weight below 60 kg tended to excrete lower urine creatinine concentrations. 50% of the volunteers with a BMI < 20 kg/m2 and 20% of the volunteers with a BMI > 20 kg/m2 exhibited creatinine concentrations below the threshold value of 20 mg/dL. A similar pattern was established for gravity and osmolality. Due to its simple determination, creatinine may be preferred over specific gravity or osmolality. In order to evaluate the internal dilution of a urine sample for legally defensible drug testing, it may be necessary to account for sex and body weight. PMID- 30276982 TI - Noncanonical features and modifications on the 5'-end of bacterial sRNAs and mRNAs. AB - Although many eukaryotic transcripts contain cap structures, it has been long thought that bacterial RNAs do not carry any special modifications on their 5' ends. In bacteria, primary transcripts are produced by transcription initiated with a nucleoside triphosphate and are therefore triphosphorylated on 5'-ends. Some transcripts are then processed by nucleases that yield monophosphorylated RNAs for specific cellular activities. Many primary transcripts are also converted to monophosphorylated species by removal of the terminal pyrophosphate for 5'-end-dependent degradation. Recent studies surprisingly revealed an expanded repertoire of chemical groups on 5'-ends of bacterial RNAs. In addition to mono- and triphosphorylated moieties, some mRNAs and sRNAs contain cap-like structures and diphosphates on their 5'-ends. Although incorporation and removal of these groups have become better understood in recent years, the physiological significance of these modifications remain obscure. This review highlights recent studies aimed at identification and elucidation of novel modifications on the 5' ends of bacterial RNAs and discusses possible physiological applications of the modified RNAs.

AB - OBJECTIVE: To assess academic performance in singletons aged 15-16 years conceived after frozen embryo transfer (FET) compared with singletons born after fresh embryo transfer (ET) in Danish cohorts born from 1995 to 2001. DESIGN: Danish national registry-based cohort study. SETTING: Danish national registries. POPULATION: All 6495 singletons conceived after assisted reproductive technology (ART) treatment in Denmark from 1995 to 2001 [FET (n) = 423; fresh ET (n) = 6072]. METHODS: Mean test scores on a national standardised and international comparable grading-scale. Comparisons of test score were first made in univariate analysis (Model 1) and secondly in a multivariate linear model (Model 2) adjusting for relevant reproductive and socio-demographic covariates such as the occupational and educational level of the parents. Sensitivity analyses on FET IVF (in vitro fertilisation) versus fresh ET-IVF and FET-ICSI (intracytoplasmic sperm injection) versus fresh ET-ICSI were made. Linear mixed models were used to account for the correlation in test scores of siblings for continuous outcome. MAIN OUTCOME MEASURES: Mean overall test score and test score in Danish, mathematics, English, and physics/chemistry. RESULTS: Crude and adjusted mean test scores were similar for adolescents conceived after FET compared with fresh ET. The crude mean difference was +0.11 (95% CI -0.11; 0.34), and the adjusted mean difference was +0.12 (95% CI -0.09; 0.34). CONCLUSIONS: Adolescents conceived after FET had similar academic performance at 15-16 of years of age compared with children conceived after fresh ET. TWEETABLE ABSTRACT: Using frozen embryos in fertility treatment does not affect school performance in Danish adolescents aged 15-16 years.

AB - Sterically unencumbered diborenes based on a benzylphosphine chelate undergo diboration reactions with bis(catecholato)diboron in the absence of a catalyst to yield tetraboranes. The symmetrical diborenes studied undergo 1,2-diborations, whereas an unsymmetrical derivative was found to yield a triborylborane-phosphine adduct as the result of a formal 1,1-diboration. A related borylborylene compound also underwent a 1,2-diboration to produce a borylene-borane adduct. PMID- 30276988 TI - The IDEAL and the EQUATOR. PMID- 30276986 TI - "Non-Naked" Gold with Glucose Oxidase-Like Activity: A Nanozyme for Tandem Catalysis. AB - It has been widely reported that "naked" gold nanoparticles (Au NPs) without protectors have glucose oxidase (GOx)-like activity, and the use of protectors can inhibit the GOx-like activity. Here, "non-naked" Au NPs with GOx-like activity are synthesized by using protein as protector. Although "naked" Au NPs have peroxidase-like activity and GOx-like activity, the optimal pH ranges of the both activities are obviously different. Fortunately, as-synthesized "non-naked" Au NPs show the dual enzyme-like activities at the same pH. So, "non-naked" Au NPs can be described as "tandem nanozyme." As another bonus, the participation of protein protector can stabilize the GOx-like activity and make Au NPs modifiable. Even though Au NPs are connected with graphene oxide (GO), the GOx-like activity is still not changed. Further, Au NPs-GO nanocomposites are applied on the one pot nonenzymatic glucose colorimetric detection. The "non-naked" gold not only broadens the species of tandem nanozymes, but also facilitates the functionalization of nanozymes, which is promising for immunoassay, biosensor, and medical treatment.

AB - Damage caused by oxygen deficiency (hypoxia) is one of the major factors limiting tissue and organ preservation time. Cooling tissues slows down metabolic rate of cells thereby prolonging tissue and organ survival sufficiently to allow transport and transplantation within a few hours. Although metabolism is slowed, cells and some enzymes continue to consume oxygen that can render cold stored tissues hypoxic. Here, an oxygen-generating composite (OGC) with sustained oxygen release is reported for ex vivo blood vessel preservation. Aorta segments are cultured under hypothermia for 25 days in vascular preservation media. The presence of OGC increases cell viability from 9 +/- 6% to 96 +/- 3% and retains 65 +/- 8% of original KCl stimulated contractile force after 25 days compared with 25 +/- 4% in controls. Culture for 7 days in nitrogen demonstrates proof-of concept for normothermic blood vessel preservation, OGC increases the cell viability from 45 +/- 15% to 78 +/- 2%, and KCl stimulates contractile force from 49 +/- 7% to 95 +/- 8%, respectively. Oxygen release materials then may have a role in augmenting current preservation techniques. PMID- 30277007 TI - Generation and characterization of anti-citrullinated protein antibody-producing B-cell clones from rheumatoid arthritis patients. AB - OBJECTIVE: Anti-citrullinated protein antibodies (ACPA) are a hallmark for rheumatoid arthritis (RA). Autoantigen-specific B-cell function aside from autoantibody production remains poorly understood in the context of this disease. We set out to elucidate this function through the isolation and immortalization of unique citrullinated protein or peptide (CP)-reactive B-cell clones from RA patients. METHODS: B-cell clones from either blood or synovial fluid of cyclic citrullinated peptide 2 (CCP2)+ RA patients were immortalized by genetic reprogramming with Bcl6 and Bcl-xL. ELISA and flow cytometry were used to identify CCP2-reactive clones and to further characterize surface marker and cytokine expression as well as B-cell receptor (BCR) signaling competence. Global gene expression profiles were interrogated by RNA sequencing. RESULTS: We generated three unique CP-reactive memory B-cell clones from two RA patients. CP reactive memory B cells did not appear to be broadly cross-reactive, but rather had a fairly restricted epitope recognition profile. These clones can secrete both pro- and anti-inflammatory cytokines and have a unique surface profile of costimulatory molecules and receptors, including CD40 and C5aRI, when compared to non-CP-reactive clones from the same patient. Additionally, CP-reactive clones bind citrullinated but not native protein and can mobilize calcium in response to antigen binding. CONCLUSIONS: CP-reactive memory B cells comprise a rare, seemingly oligoclonal population with restricted epitope-specificity and distinct phenotypic and molecular characteristics suggestive of antigen-presenting cells.

PMID- 30277006 TI - Would 1.0 cm be a more suitable cutoff to subdivide pT1 tumors in hormone receptor-negative and HER2-positive breast cancer? AB - BACKGROUND: HER2+ and hormone receptor (HoR)-negative breast cancer usually associated with poor outcome. However, it remained elusive for the prognosis of small (T1a-T1c) HER2+/HoR- breast cancer. The present study retrospectively analyzed the Surveillance, Epidemiology, and End Results (SEER) database to explore the clinicopathological characteristics and prognosis of T1a-T1c HER2+/HoR- breast cancer. MATERIAL AND METHODS: Data for patients diagnosed with either HER2-/HoR+or HER2+/HoR- T1a-T1c breast cancer between 2010 and 2012 were obtained from SEER program. Survival analyses were conducted by Kaplan-Meier method and Cox proportion hazard regression. RESULTS: Totally, 2648 HER2+/HoR- and 56387 HER2-/HoR+T1a-T1c breast cancer patients were enrolled. There was a clear trend that tumor size had a positive correlation with advanced AJCC stage (P < 0.001) and N-stage (P < 0.001). T1a and T1b HER2+/HoR- breast cancer had great homogeneity in that these two subgroups had comparable survival and both showed no significant survival difference with its counterpart of HER2 /HoR+subtype. Conversely, T1c HER2+/HoR- breast cancers revealed worse prognosis than T1a/T1b HER2+/HoR- and T1c HER2-/HoR+tumors (BCSS HR 3.847, P < 0.001; OS HR 2.055, P < 0.001). CONCLUSION: T1a and T1b HER2+/HoR- breast cancer had favorable prognosis and great homogeneity, indicating 1.0 cm may be a suitable cutoff for subclassification of T1 cancer. Future randomized clinical trials were warranted to verify this hypothesis and elucidate the biological behavior of small T1 tumor to facilitate precise medicine. PMID- 30277008 TI - Adoptive Regulatory T Cell Therapy in a Patient with Systemic Lupus Erythematosus. AB - OBJECTIVE: Regulatory T cell (Treg) adoptive cell therapy has great potential to treat autoimmune disease. Currently, very little is known about how these cells impact inflamed tissues. The purpose of this study was to elucidate how autologous Treg therapy influences tissue inflammation in human autoimmune disease. METHODS: We describe a patient with systemic lupus erythematosus (SLE) with active skin disease that received adoptive Treg therapy. We comprehensively quantify Tregs and immune activation in peripheral blood and skin with time post treatment. RESULTS: Deuterium tracking of infused Tregs revealed the transient presence of cells in peripheral blood accompanied by increased percentages of highly activated Tregs in diseased skin. Flow cytometric analysis and whole transcriptome RNA sequencing (RNAseq) revealed that Treg accumulation in skin was associated with a marked attenuation of the IFNgamma pathway and a reciprocal augmentation of the IL-17 pathway. This phenomenon was more pronounced in skin relative to peripheral blood. To validate these findings, we found that Treg adoptive transfer in a murine model of skin inflammation also resulted in a pronounced skewing away from Th1 immunity and towards IL-17 production. CONCLUSIONS: We report the first case of a patient with SLE treated with autologous adoptive Treg therapy. Taken together, our results suggest that this treatment results in increased activated Tregs in inflamed skin with a dynamic shift from Th1 to Th17 responses. This article is protected by copyright.

AB - Electrocatalytic water splitting is one of the most promising sustainable energy conversion technologies, but is limited by the sluggish electrochemical reactions. Inorganic nanomaterials have been widely used as efficient catalysts for promoting the electrochemical kinetics. Several approaches to optimize activities of these nanocatalysts have been developed. The electronic structures of the catalysts play a pivotal role in governing the activity and thus have been identified as an essential descriptor. However, the underlying working mechanisms related to the refined electronic structures remain elusive. To establish the structure-electronic behavior-activity relationship, a comprehensive overview of the developed strategies to regulate the electronic structures is presented, emphasizing the surface modification, strain, phase transition and heterostructure. Current challenges to the fundamental understanding of electron behaviors in the nanocatalysts are fully discussed. PMID- 30277010 TI - The green microalga Lobosphaera incisa harbours an arachidonate 15S-lipoxygenase. AB - The green microalga Lobosphaera incisa is an oleaginous eukaryotic alga that is rich in arachidonic acid (20:4). Being rich in this polyunsaturated fatty acid (PUFA), however, makes it sensitive to oxidation. In plants, lipoxygenases (LOXs) are the major enzymes that oxidise these molecules. Here, we describe, to our best knowledge, the first characterisation of a cDNA encoding a LOX (LiLOX) from a green alga. To obtain first insights into its function, we expressed it in E. coli, purified the recombinant enzyme and analysed its enzyme activity. The protein sequence suggests that LiLOX and plastidic LOXs from bryophytes and flowering plants may share a common ancestor. The fact that LiLOX oxidises all PUFAs tested with a consistent oxidation on the carbon n-6, suggests that PUFAs enter the substrate channel through their methyl group first (tail first). Additionally, LiLOX form the fatty acid hydroperoxide in strict S configuration. LiLOX may represent a good model to study plastid LOX, because it is stable after heterologous expression in E. coli and highly active in vitro. Moreover, as the first characterised LOX from green microalgae, it opens the possibility to study endogenous LOX pathways in these organisms. PMID- 30277011 TI - Specific association of HLA-DRB1*03 with anti-carbamylated protein antibodies in patients with RA. AB - OBJECTIVES: The new RA-specific autoantibodies, the anti-carbamylated protein antibodies (ACarPA), provide an opportunity to improve management and understanding of RA. However, many questions remain about them, including their relationship with HLA-DRB1 alleles. MATERIAL AND METHODS: The samples of 1126 RA patients from three collections were obtained. Serum reactivity against in vitro carbamylated FCS proteins was determined by ELISA. HLA-DRB1 alleles were determined by either hybridization techniques or imputation from HLA dense genotypes. These results were combined by meta-analysis with data from three previously reported cohorts. The carrier frequencies of the common HLA-DRB1 alleles were compared between the antibody-positive subgroups and the double negative subgroup in ACPA/ACarPA stratified patients, and between the four patient strata and the healthy controls. RESULTS: Meta-analysis was conducted with 3709 RA patients and 2305 healthy subjects. It revealed a significant increase of HLA-DRB1*03 carriers in the ACPA- /ACarPA+ subgroup in comparison with both ACPA- /ACarPA- patients and healthy controls that was consistent in the six sample collections. This association was independent of the SE and the analyzed confounders. No other allele was specifically associated with ACPA- /ACarPA+ patients. In contrast, the SE was significantly increased in the ACPA+ /ACarPA- and ACPA+ /ACarPA+ patient subgroups without distinction between them. Also, some alleles (including HLA-DRB1*03) were associated with protection from ACPA+ RA. CONCLUSION: A specific association of HLA-DRB1*03 with ACPA- /ACarPA+ RA has been identified that suggests preferential presentation of carbamylated peptides as a new mechanism for HLA contribution to RA susceptibility.

AB - The BRAF kinase and the MAPK pathway are targets of current melanoma therapies. However, MAPK pathway inhibition results in dynamic changes of downstream targets that can counteract inhibitor-action not only in during treatment, but also in acquired resistant tumours. One such dynamic change involves the expression of the transcription factor MITF, a crucial regulator of cell survival and proliferation in untreated as well as drug-addicted acquired resistant melanoma. Tight control over MITF expression levels is required for optimal melanoma growth, and while it is well established that the MAPK pathway regulates MITF expression, the actual mechanism is insufficiently understood. We reveal here, how BRAF through action on the transcription factors BRN2 and PAX3 executes control over the regulation of MITF expression in a manner that allows for considerable plasticity. This plasticity provides robustness to the BRAF mediated MITF regulation and explains the dynamics in MITF expression that are observed in patients in response to MAPK inhibitor therapy.

AB - The American Transplant Congress (ATC) 2018 event brought over 5000 attendees to Seattle, WA in June 2018. As the joint meeting of the American Society of Transplant Surgeons (ASTS) and the American Society of Transplantation (AST), the Congress provides exposures to cutting-edge scientific research findings for a diverse mix of physicians, surgeons, scientists, nurses, organ procurement personnel, advanced transplant providers, pharmacists, administrators, and other transplant professionals. The 5-day event featured nearly 1800 abstracts, over 500 oral presentations, and more than 1200 poster presentations, all delivered in a way that encouraged the exchange of new clinical and scientific information and supported an interchange of opinions regarding care management and socioeconomic, ethical, and regulatory issues relevant to organ and tissue transplantation. We present here the outstanding abstracts presented at ATC2018 divided into 3 categories of basic, translational, and clinical research. PMID- 30277014 TI - Needleless Transcutaneous Neuromodulation Accelerates Postoperative Recovery Mediated via Autonomic and Immuno-Cytokine Mechanisms in Patients With Cholecystolithiasis. AB - BACKGROUND: Postsurgical gastrointestinal disturbance is clinically characterized by the delayed passage of flatus and stool, delayed resumption of oral feeding, dyspepsia symptoms, and postsurgical pain. This study was designed 1) to evaluate the effects of needleless transcutaneous neuromodulation (TN) on postoperative recovery; 2) to investigate mechanisms of the TN involving autonomic functions in postoperative patients after removal of the gallbladder. METHODS: Sixty patients scheduled for laparoscopic cholecystectomy (LC) were randomized to TN (n = 30) and sham-TN (n = 30). TN was performed via acupoints ST36 and PC6 for 30 min twice daily from 24 hours before surgery to 72 hours after surgery. Sham-TN was performed using the same parameters at nonacupoints. RESULTS: 1) Compared to sham TN, TN shortened time to first flatulence (38.9 +/- 4.0 vs. 24.9 +/- 2.4 hour, p = 0.004) and time to defecation (63.1 +/- 4.5 vs. 42.5 +/- 3.1 hour, p < 0.001). 2) Compared to sham-TN, TN increased the percentage of normal pace-making activity (66.2 +/- 2.2 vs. 73.8 +/- 2.3%, p = 0.018). 3) TN enhanced vagal activity. Compared to that 24 hours before surgery, surgery decreased vagal activity (HF) (0.41 +/- 0.02 vs. 0.34 +/- 0.02, p = 0.043) 3 hours after the operation. Compared to sham-TN, TN increased HF (0.45 +/- 0.02 vs. 0.52 +/- 0.02, p = 0.045) 72 hours after the operation. Further, HF was negatively correlated with time to defecation and serum norepinephrine. 4) Surgery increased serum IL-6 (1.1 +/- 0.1 before surgery vs. 2.9 +/- 0.7 pg/mL, p = 0.041) 72 hours after the operation, which was reduced to baseline by TN (0.9 +/- 0.1). CONCLUSIONS: In conclusion, the proposed needleless TN accelerates postoperative recovery after LC, possibly mediated via the autonomic and immune-cytokine mechanisms. Needleless and self-administrable TN may be an easy-to-implement and low-cost complementary therapy for postoperative recovery. PMID- 30277015 TI - Association of hypocalcemia with congenital heart disease in 22q11.2 deletion syndrome. AB - Hypocalcemia is one of the cardinal features of the chromosome 22q11.2 deletion syndrome (22q11.2DS), the most common cause of DiGeorge syndrome. Hypocalcemia and other features of 22q11.2DS including congenital heart disease (CHD) are primarily ascribed to problems with morphogenesis and function of the pharyngeal arch system derivatives including the parathyroid glands, the aortic arch, and the cardiac outflow tract. In light of the aforementioned embryology, we hypothesized that hypocalcemia would be identified more frequently in those patients with 22q11.2DS and CHD. We conducted a retrospective IRB approved chart review on 1,300 subjects with 22q11.2DS evaluated at the Children's Hospital of Philadelphia. chi2 test was used to evaluate the statistical significance of differences in hypocalcemia between the two groups. Eight hundred fifty-two patients had calcium levels available for review. Of these, 466 (54.69%) had a history of hypocalcemia and 550 (64.55%) had CHD. Of those with CHD, 343 (62.36%) had a history of hypocalcemia, and of those without CHD, only 123 (40.73%) had a history of hypocalcemia. Thus, the frequency of diagnosed hypocalcemia was greater in patients with 22q11.2DS and CHD as compared to those without CHD (p < .001). We also analyzed age of onset of hypocalcemia and found that 66.47% of CHD/hypocalcemia group had neonatal/infantile hypocalcemia versus 43.09% in the non-CHD/hypocalcemia group. In our large cohort of patients with 22q11.2DS, the prevalence of diagnosed hypocalcemia is elevated among patients with CHD, in whom it is more likely to be diagnosed during the neonatal/infancy period.

PMID- 30277016 TI - Clinical complete response after chemoradiotherapy for carcinoma of thoracic esophagus: Is esophagectomy always necessary? A systematic review and meta analysis. AB - BACKGROUND: Although a clinical complete response (cCR) after chemoradiotherapy (CRT) could lead to a better prognosis, the choice of a following strategy, such as surgical or non-surgical approach, remains controversial. METHODS: All articles relevant to a comparison of surgical and non-surgical treatment (including further definitive chemoradiotherapy or active surveillance) for esophageal carcinoma patients with a cCR after CRT were retrieved for meta analysis. The final date for data retrieval was 30 June 2018. RESULTS: Four retrospective studies including 648 patients met the inclusion criteria: 620 with squamous cell carcinoma and 28 with adenocarcinoma. The CRT + surgery group had an advantage over the non-surgery group in regard to two-year disease-free survival (DFS); however, the two groups showed similar results in five-year DFS. The CRT + surgery group had an advantage over the non-surgery group in two-year overall survival (OS); nevertheless, the two groups showed similar results in five-year OS. CONCLUSIONS: Based on the available evidence, the addition of surgery to thoracic locally advanced esophageal carcinoma patients with a cCR after neoadjuvant CRT provided no advantage to long-term survival. As an exception, the two-year DFS and OS could be improved. This research conclusion might be more suitable to patients with squamous cell carcinoma.

AB - Aluminum, a cost-effective and abundant metal capable of alloying with Li up to around 1000 mAh g-1 , is a very appealing anode material for high energy density lithium-ion batteries (LIBs). However, despite repeated efforts in the past three decades, reports presenting stable cycling performance are extremely rare. This study concerns recent findings on the highly reversible (de)lithiation of a micro sized Al anode (m-Al) by using bis(fluorosulfonyl)imide (FSI)-based electrolytes. By using this kind of electrolyte, m-Al can deliver a specific capacity over 900 mAh g-1 and superior Coulombic efficiency (96.8 %) to traditional carbonate- and glyme-based electrolytes (87.8 % and 88.1 %, respectively), which represents the best performance ever obtained for an Al anode without sophisticated structure design. The significantly improved electrochemical performance, which paves the way to realizing high-performance Al-based high energy density LIBs, can be attributed the peculiar solid-electrolyte interphase (SEI) formed by the FSI containing electrolyte.

AB - In this unit, methods for the analysis of integrin-dependent adhesion are described. Two major types of assays are commonly used for this analysis. The first are cell adhesion assays. A key application of this type of assay is to identify which integrin(s) mediate cell-substrate interactions; a comprehensive list of antibodies suitable for this purpose is detailed. The second are solid phase assays in which purified integrins and integrin ligands are used. These assays can be used, e.g., to measure apparent affinities of integrins for different ligands and IC50 values of pharmacological inhibitors. Curr. Protoc. Cell Biol. 53:9.4.1-9.4.17.

AB - Treatment of heterocyclic amines featuring fused rings of [1,2,4]triazolo[4,3 b][1,2,4,5]tetrazine with fuming HNO3 /P2 O5 leads to six fully characterized explosives through multiple nitration and reduction or oxidation mechanism. Thus, 4-nitro-N-(3-nitro[1,2,4]triazolo[4,3-b][1,2,4,5]tetrazin-6-yl)-1,2,5-oxadiazol-3 amine (3 b, TTDNF) showed high performance (D=9180 m s-1 , P=36.7 GPa) and low impact sensitivity (IS>40 J) while N-([1,2,4]triazolo[4,3-b][1,2,4,5]tetrazin-6 yl)-3-nitro-1,2,4-oxadiazol-5-amine (4 a, TTNOA) exhibited a potential cast explosive component with low melting point at 88.2 degrees C and high onset decomposition temperature at 226.2 degrees C. PMID- 30277024 TI - Body Composition Percentiles in Urban South Indian Children and Adolescents. AB - OBJECTIVE: This study aimed to generate age- and sex-specific percentiles for body composition indices in children and to assess the variability in these indices, in relation to BMI. METHODS: Anthropometry and body fat were measured with the BOD POD (Cosmed; Rome, Italy) in 9,702 children from Bangalore, India. Smoothed percentile curves using the lambda-mu-sigma method were obtained for BMI, fat-free mass index (FFMI), fat mass index (FMI), and body fat percentage (% BF). RESULTS: Percentile curves for % BF and FMI in boys increased from 6 to 12 years and declined from 13 years on, while in girls, it increased until 15 years. The FFMI percentile curves increased with age in both sexes. The mean FMI declined from 12 years on in boys, corresponding to a large increase in FFMI from that age, while in girls, both FMI and FFMI continued to increase. The 75th percentile of % BF and FMI had greater sensitivity to identify children with obesity. CONCLUSIONS: This study developed smoothed percentile curves for body composition in Indian children and suggests FMI and FFMI as good indicators of growth in children. PMID- 30277023 TI - Prostate cancer survivors: Risk and mortality in second primary cancers. AB - To assess etiological and clinical consequences of second primary cancers (SPCs) in prostate cancer (PC) patients, we followed newly diagnosed patients to identify men who were diagnosed with a SPC and recorded their causes of death. We used the Swedish Family-Cancer Database to assess relative risks (RRs) and causes of death in SPCs until the year 2015 in patients with a PC diagnosis between 2001 and 2010. Among a total of 4.26 million men, 76 614 were diagnosed with PC at the median age of 71 years. Among them, 8659 (11.3%) received a subsequent diagnosis of SPC after a median follow-up of 4 years. The most common SPCs were colorectal, skin, bladder, and lung cancers, melanoma, and non-Hodgkin lymphoma. The ranking was almost identical with first cancers among elderly men in Sweden. The RR for SPCs in prostate-specific antigen-detected PC was approximately equal to RR in other PC. Mortality patterns of PC patients were distinct depending on the presence or absence of SPC. Among patients with SPC, 47.8% died as a result of the corresponding SPC, followed by other causes (22.2%) and PC (18.1%). For patients without SPC, PC and non-neoplastic causes almost matched each other as the main causes of death (48.5% and 47.8%). The results suggest that SPCs appear autonomous from primary PC and reflect incidence and mortality of first cancers in general. SPC was the most common cause of death in patients with SPC; close to half of the patients died due to SPC. For improved survival in PC patients, prevention and early detection of SPCs would be important, and the present results suggest that risk factors for SPC in PC are the same as those for first cancer in general.

AB - OBJECTIVE: This study aimed to investigate the associations of sleep duration and sleep quality with visceral adipose tissue (VAT) in middle-aged individuals. METHODS: In this cross-sectional analysis of baseline measurements of the Netherlands Epidemiology of Obesity (NEO) study, participants underwent anthropometry and completed the Pittsburgh Sleep Quality Index (PSQI) for assessing short sleep duration (as sex-specific age-adjusted percentiles) and poor quality (PSQI > 5). VAT was assessed by magnetic resonance imaging in a random subgroup. We performed linear regression analyses to examine associations of short sleep and poor sleep with measures of body fat, adjusted for confounding, including total body fat in models with VAT. RESULTS: A total of 5,094 participants (52% women; mean age of 56 [SD 6] years), 1,947 of whom had VAT measurements, were analyzed. The difference in VAT between poor sleep (PSQI > 5) and good sleep (PSQI <= 5) was 7.2cm2 (95% CI: 1.2-13.8) in women and 16.1cm2 (95% CI: 6.2-26.0) in men. These differences attenuated toward the null after the adjustment for total body fat. Similar patterns of associations were observed for short sleep (lowest 10% compared with median 60%). CONCLUSIONS: Our results suggest that measures of sleep are not specifically associated with a higher amount of VAT. PMID- 30277029 TI - Anthropometry Versus Imaging for Prediction of Inflammation Among Hispanic Girls. AB - OBJECTIVE: This study aimed to compare total and regional estimates of body composition, by direct and indirect techniques, for the optimal prediction of C reactive protein (CRP) among young (aged 9-12 years) Hispanic girls (N = 232). METHODS: Standard anthropometric techniques were used to measure height, weight, and waist circumference. Dual-energy X-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT) assessed body composition. Fasting serum CRP was measured by the AU5812 Clinical Chemistry Analyzer (Beckman Coulter, Brea, California). Associations between each total and regional body composition parameter and CRP were tested using linear regression (log-transformed, continuous CRP) and ordinal logistic regression (CRP < 1.0, >= 1.0-2.9, and >= 3.0 mg/L), controlling for maturation, dietary energy, physical activity, and medications. RESULTS: All measures of total and regional body fat were positively associated with CRP (P < 0.0001) except for intermuscular fat by pQCT. There were no clinically relevant differences in their association with CRP between anthropometric (BMI; waist circumference) and DXA-derived (total fat and regional fat: trunk, gynoid, android fat, leg) measures of fat. CONCLUSIONS: Measurement of body habitus in Hispanic girls, by multiple commonly available means, predicts CRP equally well. PMID- 30277030 TI - Dissemination of the Look AHEAD Intensive Lifestyle Intervention in the United States Military: A Randomized Controlled Trial. AB - OBJECTIVE: The purpose of this study, "Fit Blue," was to compare a translation of the Look AHEAD (Action for Heath in Diabetes) intensive lifestyle intervention with a self-paced version of the same intervention among active duty military personnel. METHODS: Active duty military personnel (N = 248; 49% male, 34% racial minority) with overweight or obesity were randomized to 12-month distance-based (i.e., phone and email) parallel programs, counselor-initiated (CI) condition or self-paced (SP) condition, from 2014 to 2016. Trained lay interventionists were retired military personnel or had extensive familiarity with the military. RESULTS: The CI condition had greater weight loss at 4 months (CI: mean +/- SD = 3.2 +/- 3.4 kg; SP: -0.6 +/- 2.9 kg; P < 0.0001) and at 12 months (CI: mean +/- SD = -1.9 +/- 4.1 kg; SP: -0.1 +/- 3.8 kg; P < 0.001). Participants in the CI condition also had a greater percent weight loss at both 4 months (CI: 3.5% +/- 3.8, SP: 0.6% +/- 3.1; P < 0.0001) and 12 months (CI: 2.1% +/- 4.7, SP: 0.0% +/- 4.0; P < 0.001). In addition, a greater proportion of CI participants lost 5% or more at 4 months (CI: 29.8%, SP: 10.5%; P < 0.001) and at 12 months (CI: 29.5%, SP: 15.6%; P < 0.05). CONCLUSIONS: The CI behavioral weight loss intervention translated from Look AHEAD was well received and is a promising approach for managing weight in an active duty military population. PMID- 30277031 TI - Changes in the Perceptions of Self-weighing Across Time in a Behavioral Weight Loss Intervention. AB - OBJECTIVE: Changes in beliefs about self-weighing were examined across time in a behavioral weight loss intervention. METHODS: Active duty military personnel (n = 248) enrolled in a 12-month counselor-initiated or self-paced intervention based on the Look AHEAD (Action for Health in Diabetes) Intensive Lifestyle Intervention. Using an electronic scale, participants were asked to self-weigh daily. Self-weighing perceptions were compared from baseline to 4 months (weight loss phase), from 4 months to 12 months (weight maintenance phase), and from baseline to 12 months (full intervention), as well as across time by behavioral and demographic characteristics. RESULTS: Overall, participants perceived self weighing as more helpful and positive, less frustrating, and making them less self-conscious after the weight loss phase. After weight maintenance, individuals believed self-weighing was less helpful and positive, more frustrating and anxiety provoking, and making them more self-conscious. However, after the intervention, participants still viewed self-weighing as more helpful and positive and less frustrating than at baseline. Weight change, self-weighing behavior prior to the intervention, and intervention condition were associated with perception change. Controlling for these influencing factors, differences in gender, BMI, age, ethnicity, and race were observed in how beliefs changed across time. CONCLUSIONS: Results suggest engaging in a weight loss intervention promoting daily self-weighing increases positive and decreases negative beliefs about self-weighing. PMID- 30277033 TI - Quantitative analysis of liver tumors at different stages using microscopic hyperspectral imaging technology. AB - Liver cancer has one of the highest rates of human morbidity and mortality. However, in terms of pathology, liver cancer is traditionally clinically diagnosed based on observation of microscopic images of pathological liver sections. This paper investigates in vitro samples of rat models of bile duct carcinoma and presents a quantitative analysis method based on microscopic hyperspectral imaging technology to evaluate liver cancers at different stages. The example-based feature extraction method used in this paper mainly includes two algorithms: a morphological watershed algorithm is applied to find object and segment pathological components of pathological liver sections at different stages, and a support vector machine algorithm is implemented for liver tumor classification. Majority/minority analysis is utilized as the postclassification tool to eliminate small plaques from the preliminary classification results. Then, pseudocolor synthesis in RGB color space is used to produce the final results. The experimental results show that this method can effectively calculate the percent tumor areas in liver biopsies at different time points, that is, 3.338%, 11.952%, 15.125%, and 23.375% at 8, 12, 16, and 20 weeks, respectively. Notably, through tracking analysis, the processed results of 8-week images showed the possibility for early diagnosis of the liver tumor. PMID- 30277032 TI - Structured polarized light microscopy for collagen fiber structure and orientation quantification in thick ocular tissues. AB - Collagen is a major constituent of the eye and understanding its architecture and biomechanics is critical to preserve and restore vision. We, recently, demonstrated polarized light microscopy (PLM) as a powerful technique for measuring properties of the collagen fibers of the eye, such as spatial distribution and orientation. Our implementation of PLM, however, required sectioning the tissues for imaging using transmitted light. This is problematic because it limits analysis to thin sections. This is not only slow, but precludes study of dynamic events such as pressure-induced deformations, which are central to the role of collagen. We introduce structured polarized light microscopy (SPLM), an imaging technique that combines structured light illumination with PLM to allow imaging and measurement of collagen fiber properties in thick ocular tissues. Using pig and sheep eyes, we show that SPLM rejects diffuse background light effectively in thick tissues, significantly enhancing visualization of optic nerve head (ONH) structures, such as the lamina cribrosa, and improving the accuracy of the collagen fiber orientation measurements. Further, we demonstrate the integration of SPLM with an inflation device to enable direct visualization, deformation tracking, and quantification of collagen fibers in ONHs while under controlled pressure.

AB - BAKGRUNN: For a kunne mote helseutfordringer i befolkningen trenger vi oversikt over befolkningens helsetilstand. I Norge har vi tradisjonelt hatt god oversikt over dodsarsaker, men vi vet mindre om byrden fra tilstander som medforer sykelighet, sakalt ikke-dodelig helsetap. Vart mal var a beskrive den totale sykdomsbyrden i Norge i 2016, utviklingen de siste ti arene samt kjonnsforskjeller i sykdomsbyrde. MATERIALE OG METODE: Vi brukte resultater fra det globale sykdomsbyrdeprosjektet Global Burden of Diseases, Injuries and Risk Factors Study (GBD), som kvantifiserer ikke-dodelig helsetap slik at det kan males pa samme skala som dodelighet i form av tapte levear. Summen av tapte levear og ikke-dodelig helsetap gir sykdomsbyrdemalet helsetapsjusterte levear (DALY). RESULTATER: Ikke-smittsomme sykdommer som hjerte- og karsykdom, kreft, kronisk obstruktiv lungesykdom og demens var viktige arsaker til tapte levear hos begge kjonn i Norge i 2016. Ikke-dodelig helsetap utgjorde 52 % av sykdomsbyrden malt i helsetapsjusterte levear. Spesielt muskel- og skjelettsykdommer, psykiske lidelser og ruslidelser var viktige. De siste ti arene har sykdomsbyrden (i aldersjusterte rater) sunket for mange tilstander som medforer tapte levear, men ikke for tilstander som gir ikke-dodelig helsetap. FORTOLKNING: Ikke-dodelig helsetap utgjor en stor og okende andel av sykdomsbyrden i den norske befolkningen, noe som vil gi nye utfordringer for helsevesenet.

AB - BACKGROUND: The withdrawal of digitoxin and subsequent substitution with digoxin around 2012 may have led to an increased health risk for patients. The aim of this study was to follow individual patients during the switch. MATERIAL AND METHOD: Serum concentrations of digitoxin and digoxin, measured at the Department of Clinical Pharmacology at St Olavs University Hospital in the period 1 January 2011-31 December 2013 were reviewed. Patients who had switched from digitoxin to digoxin and whose serum concentrations of both drugs had been measured during this period were included. RESULTS: A total of 304 patients, 1686 samples and 1858 serum concentration analyses were included in the study. Therapeutic serum concentrations were measured in 171 patients (56.3 %) before the switch and 176 (57.9 %) after this had taken place. Altogether 108 patients (35.5 %) had therapeutic concentrations both before and after the change. For 58.9 % of the patients, the change resulted in a reduction in serum concentration of digitalis, calculated as digoxin equivalents. The proportion of patients with assumed supratherapeutic concentrations fell from 43.1 % to 33.9 %; however, the proportion of patients with toxic serum concentrations rose from 0.3 % to 3.0 %. INTERPRETATION: Although the switch led to a reduction in dose and serum concentration for many, a significant number of patients may have been put in harm's way. PMID- 30277050 TI - ?

AB - A variety of early ontogenetic events of anuran species (growth, structural and biochemical diversification,metamorphosis) offers a unique opportunity to evaluate the effectiveness and application limits ofmass spectrometry method for the analysis of metabolic and transformation events in developing organisms.The dynamics of relative carbon and nitrogen contents and stable isotopes of these elements during larvaldevelopment in the period of metamorphosis climax and after its conclusion in moor frog specimens developingin their natural habitat and in vitro on a referent diet are traced. A decrease in C/N ratio and enrichmentof the tissues with heavy stable isotopes of carbon and nitrogen during embryonal and larval development(prior to the beginning of independent feeding) indicates the increase in the portion and variety of proteins,accompanied by consumption of yolk lipids. The relative nitrogen content increase and C/N ratio decreaseswith the growth and development of independently feeding tadpoles, which indicates surpassing increase ofthe portion of proteins in tissues. In growing tadpoles, the rates of tissue renewal in general and rates of proteinmetabolism in particular affect the kinetics of changes of tissue isotope composition, which approaches isotopecomposition of the consumed food. A decrease in S/N ratio in the bodies of metamorphs during masstissue decomposition is indicative of continuing reconstruction of larval organs and growth of anlage of definitiveorgans. Significant increase of C/N ratio and depletion of liver samples by heavy carbon isotopes areassociated with intensive synthesis and reservation of lipids within the organ. Strong enrichment of metamorphs'tissues with heavy nitrogen isotope indicates the substitution of ammoniotelic type of nitrogenmetabolism by urotelic type. Decrease in C/N ratio and enrichment of tissues by heavy carbon isotope maybe connected to intensive oxidation of lipids, which supports the growing energy costs of terrestrial underyearlings.Relative contents of heavy nitrogen isotope in the tissues of underyearlings does not change comparedto the tissues of metamorphs.

AB - The effectiveness of two transplantation methods of human hepatocellular carcinoma cells HepG2and allogeneic mesenchymal stromal cells of adipose tissue (AT MSCs) into mice was compared in order toselect the most effective for liver damage repair. Considerable advantage of cell transplantation into the spleencompared with intraperitoneal administration was shown. It is found that, under similar conditions of transplantation,AT MSCs are detected in liver tissue in smaller quantities than human hepatocellular carcinomacells HepG2; differences in cell localization of these types of cells in the liver are revealed. A tendency todecrease in the degree of fibrotic changes in liver tissue after transplantation of AT MSCs and to a greaterextent after transplantation of AT MSCs, pretreated with interleukin-6, was traced.

AB - Inspired by the well-known "Wheel of Fortune", a rotatable paper photocontrollable switch (RPPS) was designed to form an addressable paper-based photoelectrochemical (PEC) cyto-sensor for ultrasensitive detection of a cell surface protein. By simply rotating the RPPS, a light source can selectively activate the desired working zones of the cyto-sensor. To realize the high performance paper-based PEC cyto-sensor, a cascaded photoactive interface consisting of neat TiO2 nanotubes arrays, Pt nanoparticles (NPs), and nitrogen carbon dots was introduced into paper fibers, gaining signal-on PEC state (NTPP for short). Then the NTPP fixed with a hairpin probe H1 allowed the hybridization chain reaction (HCR) to happen with CuS NPs-labeled hairpin probe H2 by the free primer strand (PS) triggering; hence, the CuS NPs as the emulative sensitizers were introduced onto the NTPP with the photocurrent intensity decrement for signal-off PEC state. During this process, the PS carefully designed with specific sequences can recognize the target strand (TS) of MCF-7 cells and stimulate HCR by its trigger zone. The presence of MCF-7 cells destroyed the interaction between PS and ZnFe2O4 functionalized TS, causing the PS release from the mixture of PS and TS under the help of a magnet. Then, the released PS, acting as a primer probe, realized ultrasensitive detection of a cell-surface protein. On the basis of this novel protocol, multiple-signal amplification was skillfully imported into the addressable paper PEC chip, resulting in ultrasensitive quantification of carcinoembryonic antigen in the surface of MCF-7 cells. Given the fascinating analytical performances of the developed cyto sensor, ultralow expression of antigens for MCF-7, A549, and PC 3 cells was discriminated effectively.

AB - Oxygen vacancy (VO) formation energy and its migration barrier are two determining factors for the effectiveness of solid electrolytes (SEs) in solid oxide fuel cells (SOFCs). In this work, a series of aliovalent rare-earth-doped ceria (Ln xCe1- xO2-delta, Ln = lanthanides) compounds serving as SEs are comprehensively and comparatively calculated, through which the determinant factors for oxygen vacancy formations and their migration activity are figured out at an atomistic level via the first-principles calculations with the consideration of electronic correlations. Initially, it is found that the oxygen vacancy formation energies of the Ln-doped ceria are largely reduced in contrast to the undoped ceria (CeO2-delta), which obviously agree with the literature. Then, the migration activity of an oxygen vacancy in Ln xCe1- xO2-delta is closely correlated to the association energies of Ln-VO, in which the different 4f5d bonding properties for different Ln ions should be taken into account. Additionally, the analysis of charge difference gradient (CDG) is revealed to be the intrinsic driving force for oxygen vacancy migration. We hope that our investigation provides a microscopic insight into the oxygen vacancy defect physics, and it is also a benefit for the design of more advanced relevant functional materials. PMID- 30277057 TI - Live Monitoring of Microenvironmental pH Based on Extracellular Acidosis around Cancer Cells with Cell-Coupled Gate Ion-Sensitive Field-Effect Transistor. AB - We demonstrated the live monitoring of cellular respiration using an ion sensitive field-effect transistor (ISFET), focusing on different types of living cells, namely cancer and normal cells. In particular, we realized the label-free, real-time, and noninvasive monitoring of microenvironmental pH behavior based on extracellular acidosis around cancer cells in the long term and in situ. The change in interfacial pH (DeltapHint), which was analyzed based on the change in interfacial potential (Delta Vout) at the cell/gate nanogap interface gradually decreased for every cell-based ISFET. Moreover, the DeltapHint for cancer cells shifted by a factor of 5 to 6, which was larger than that for normal cells. This is because cancer cells cause dysbolism and are activated, thereby suppressing oxidative phosphorylation in mitochondria so as not to induce their apoptosis. Therefore, cancer cellular respiration proceeds via the glycolysis pathway, through which lactic acid is eventually released. Additionally, the pH sensitivity of the ISFET device was maintained even when the device was immersed into a cell culture medium for 24 h and 1 w; thus, the effect of nonspecific adsorption of proteins contained in the medium on the pH sensitivity of the ISFET device was negligible in the live monitoring of cellular respiration. PMID- 30277058 TI - Chemical Sensing in Real Time with Plants Using a Webcam. AB - It has been established that plants can smell and respond to chemicals in order to adapt to and survive in a changing chemical environment. Here we show that a plant responds to chemicals in air, and the response can be detected rapidly to allow tracking of air pollution in real time. We demonstrate this capability by detecting subtle color and shape changes in the leaves of mosses upon exposure to sulfur dioxide in air with a simple webcam and an imaging-processing algorithm. The leaves of mosses consist of a monolayer of cells, providing a large surface to-volume ratio for highly sensitive chemical sensing. The plant sensor responds linearly to sulfur dioxide within a wide concentration range (0-180 ppm), and it can tolerate humidity variation (15-85% relative humidity) and chemical interference and regenerate itself. We envision that plants can help alert chemical exposure danger as a part of our living environment using low-cost CMOS imagers, and their chemical-sensing capabilities may be further improved with genetic engineering.

AB - Organic/inorganic hybrid complementary inverters operating at low voltages (1 V or less) were fabricated by transfer-stamping organic p-type poly(3 hexylthiophene) (P3HT) and inorganic n-type zinc oxide (ZnO) electrolyte-gated transistors (EGTs). A semicrystalline homopolymer-based gel electrolyte, or an ionogel, was also transfer-stamped on the semiconductors for use as a high capacitance gate insulator. For the ionogel stamping, the thermoreversible crystallization of phase-separated homopolymer crystals, which act as network cross-links, was employed to improve the contact between the gel and the semiconductor channel. The homopolymer ionogel-gated P3HT transistor exhibited a high hole mobility of 2.81 cm2/(V s), and the ionogel-gated n-type ZnO transistors also showed a high electron mobility of 2.06 cm2/(V s). The transfer stamped hybrid complementary inverter based on the P3HT and ZnO EGTs showed a low voltage operation with appropriate inversion characteristics including a high voltage gain of ~18. These results demonstrate that the transfer-stamping strategy provides a facile and reliable processing route for fabricating electrolyte-gated transistors and logic circuits.

AB - Recently, magnetic skyrmion has attracted much attention due to its potential application in racetrack memory and other nanodevices. In bulk chiral magnets with non-centrosymmetric crystal structures, skyrmion lattice phase has been extensively observed. However, in film or multilayers with interfacial Dzyaloshinskii-Moriya interaction, individual skyrmion is often observed. Here, we report a short-ordered skyrmion lattice observed in [Ta(5.0 nm)/CoFeB(1.5 nm)/MgO(1.0 nm)]15 multilayer in a remnant state. The structure, stabilization, and reversal of these skyrmions are discussed. Applying a slightly tilted in plane magnetic field caused reversal of the skyrmion lattice. This reversal came from disappearance of skyrmions and nucleation of new skyrmions in the interstitial regions of the lattice. Also, we investigated how the skyrmion lattice depended on the CoFeB thickness. Our findings provide a pathway to stabilize and reverse the skyrmions in multilayers films. PMID- 30277061 TI - Bendable InGaN Light-Emitting Nanomembranes with Tunable Emission Wavelength. AB - The integration of light-emitting diodes (LEDs) into the flexible devices has exhibited a great potential in the next-generation consumer electronics. In this study, we have demonstrated an exfoliated InGaN nanomembrane LED (NM-LED) separated from a GaN/sapphire substrate through an electrochemically wet etching process. The peak wavelengths blue-shifted phenomenon of the photoluminescence (PL) and the electroluminescence spectra were observed on the free-standing NM LED compared to the nontreated LED with the same structure, which can be ascribed to the partial strain relaxation of the LED structure confirmed by the Raman spectra and the X-ray diffraction curves. A small divergent angle of the PL emission light has also been observed on the NM-LED. Moreover, the peak emission wavelength of this NM-LED can be even modulated from a red shift (521.7 nm) to a blue shift (500.4 nm) compared with that of the flat state (509.4 nm) while being curved convexly from top p-GaN:Mg side to bottom n-GaN:Si side. Our study provides an elegant way to develop a bendable light source with variable emission wavelengths through the mechanical deformation method. PMID- 30277062 TI - Satellite-based land-use regression for continental-scale long-term ambient PM2.5 exposure assessment in Australia. AB - Australia has relatively diverse sources and low concentrations of ambient fine particulate matter (<2.5 um, PM2.5). Few comparable regions are available to evaluate the utility of continental-scale land-use regression (LUR) models including global geophysical estimates of PM2.5, derived by relating satellite observed aerosol optical depth to ground-level PM2.5 ('SAT-PM2.5'). We aimed to determine the validity of such satellite-based LUR models for PM2.5 in Australia. We used global SAT-PM2.5 estimates (~10 km grid) and local land-use predictors to develop four LUR models for year-2015 (two satellite-based, two non-satellite based). We evaluated model performance at 51 independent monitoring sites not used for model development. An LUR model that included the SAT-PM2.5 predictor variable (and six others) explained the most spatial variability in PM2.5 (adjusted R2 = 0.63, RMSE (ug/m3 [%]): 0.96 [14%]). Performance decreased modestly when evaluated (evaluation R2 = 0.52, RMSE: 1.15 [16%]). The evaluation R2 of the SAT-PM2.5 estimate alone was 0.26 (RMSE: 3.97 [56%]). SAT-PM2.5 estimates improved LUR model performance, while local land-use predictors increased the utility of global SAT-PM2.5 estimates, including enhanced characterization of within-city gradients. Our findings support the validity of continental-scale satellite-based LUR modeling for PM2.5 exposure assessment in Australia. PMID- 30277063 TI - Several Orders of Magnitude Difference in Charge-Transfer Kinetics Induced by Localized Trapped Charges on Mixed-Halide Perovskites. AB - Partial halide substitution in organolead halide perovskites MAPbX3 (MA = CH3NH3+, X = Cl-, Br-, or I-) leads to semiconductor heterostructures with precisely tuned band-gap energies, which facilitates efficient charge extraction or separation for high-performance solar cells and optoelectronic devices. In this study, partially iodide-substituted MAPbBr3 perovskites were prepared through a halide-exchange reaction in the liquid phase, and in situ space- and time-resolved photoluminescence profiles were acquired by means of confocal microscopy. The rates of charge transfer from the bulk MAPbBr3 to the surface MAPbBr3- xI x domains, which are widely distributed over a single crystal, were found to greatly depend on the excitation-power density. In particular, an abnormally slow charge-transfer process, lasting a few nanoseconds, was observed at higher excitation density. To explain the dependence of this rate on the excitation density, and its correlation with the charge-trapping rate in the bulk MAPbBr3, we propose a plausible mechanism in which trap filling associated with surface-trapped holes induces band bending within the space charge region. This band bending modulates carrier dynamics near the surface, thereby leading to efficient charge extraction from the bulk. To validate the mechanism, the carrier dynamics was numerically simulated using a diffusion model that includes the effect of the localized electric field. Our findings provide significantly deeper insight into the carrier dynamics within heterostructured perovskites with nanoscale heterogeneities, and a robust route for manipulating the photogenerated charges in various types of perovskite devices. PMID- 30277064 TI - Two-Dimensional WSe2/MoS2 p-n Heterojunction-Based Transparent Photovoltaic Cell and Its Performance Enhancement by Fluoropolymer Passivation. AB - As a means to overcome the limitation of installation space and to promote the utilization of the solar cell in various applications, a transparent thin-film solar cell has been studied by many researchers. To achieve a transparent solar cell, the choice of materials which are transparent enough and showing the photovoltaic property at the same time is the key. Here, we suggest a two dimensional (2D) p-n heterojunction of WSe2/MoS2 and an indium tin oxide electrode to fabricate a transparent thin-film photovoltaic cell. Because of advantages that 2D materials possess, a highly transparent (~80%) solar cell with considerable efficiency was achieved. Furthermore, by introducing a transparent passivation layer composed of a fluoropolymer, the photovoltaic performance was much improved. With the passivation layer, our WSe2/MoS2 transparent photovoltaic cell reached an efficiency of ~10%. A comparison of photovoltaic parameters before and after applying passivation and analysis on the origin of such differences are also discussed. To the best of our knowledge, this is the first report to fabricate a 2D material-based fully transparent photovoltaic device. Our result exhibits a great potential of the van der Waals p-n heterojunction of 2D semiconductors to be utilized for an active layer of a highly transparent and lightweight thin-film solar cell.

AB - Fluorescent active small molecules for organelle-specific bioimaging are in great demand. We synthesized 20 different pyrido-imidazo-indole fused heterocycles (6-5 5-6 ring) via copper catalyzed tandem N-arylation reaction in moderate to good yields. Due to decent fluorescent property, lysosome-directing moieties were attached on two of these heterocycles. Delightfully, those molecules tracked lysosome with bright blue fluorescence and colocalized with a known lysosome marker (Lysotracker Red) in human/murine cells. Therefore, it may be considered as a rapid (10 min) lysosome staining probe. PMID- 30277066 TI - Computational Design of Synthetic Enzymes. AB - We review the standard model for de novo computational design of enzymes, which primarily focuses on the development of an active-site geometry, composed of protein functional groups in orientations optimized to stabilize the transition state, for a novel chemical reaction not found in nature. Its emphasis is placed on the structure and energetics of the active site embedded in an accommodating protein that serves as a physical support that shields the reaction chemistry from solvent, which is typically improved upon by laboratory-directed evolution. We also provide a review of design strategies that move beyond the standard model, by placing more emphasis on the designed enzyme as a whole catalytic construct. Starting with complete de novo enzyme design examples, we consider additional design factors such as entropy of individual residues, correlated motion between side chains (mutual information), dynamical correlations of the enzyme motions that could aid the reaction, reorganization energy, and electric fields as ways to exploit the entire protein scaffold to improve upon the catalytic rate, thereby providing directed evolution with better starting sequences for increasing biocatalytic performance.

AB - It is generally deemed that doping is a must for polymeric materials to achieve their high thermoelectric performance. We herein present the first report that intrinsically metallic behaviors and high-performance thermoelectric power factors can coexist within doping-free linear-backbone conducting polymers, poly(nickel-ethylenetetrathiolate) and its analogs. On the basis of density functional calculations, we have corroborated that four crystalline pi- d conjugated transition-metal coordination polymers, including poly(Ni-C2S4), poly(Ni-C2Se4), poly(Pd-C2S4) and poly(Pt-C2S4) exhibit intrinsically metallic behavior arising from the formation of dense intermolecular interaction networks between sulfur/selenium atoms. They show moderate carrier concentrations (1019 1021 cm-3) and decent conductivities (103-104 S cm-1), among which, poly(Ni C2S4), poly(Ni-C2Se4) and poly(Pd-C2S4) possess high power factors (~103 MUW m-1 K-2).

This strategy was applied to synthesize head-to-tail cyclic antibacterial bovine lactoferricin peptide LFcinB20-35 in a yield of 67%. The one-pot strategy was compatible with an oxidative folding reaction, and complex cyclotides containing one or two disulfide bonds, such as sunflower trypsin inhibitors-1 and alpha conotoxin MII, were successfully synthesized in one pot in a yield of 77% and 61%, respectively. PMID- 30277069 TI - Realization of Thermally Stimulated Delayed Phosphorescence in Arylgold(III) Complexes and Efficient Gold(III) Based Blue-Emitting Organic Light-Emitting Devices. AB - To address and overcome the difficulties associated with the increased reactivity and susceptibility of blue emitters to deactivation pathways arising from the high-lying triplet excited states, we have successfully demonstrated an innovative strategy of harvesting triplet emission via the "thermally stimulated delayed phosphorescence" mechanism, where thermal up-conversion of excitons from the lower-energy triplet excited states (T1) to higher-energy triplet excited states (T1') are observed to generate blue emission. The lower-lying T1 excited state could serve as a mediator to populate the emissive T1' state by up conversion via reverse internal conversion, which could enhance the photoluminescence quantum yield by over 20-folds. Organic light-emitting devices with respectable external quantum efficiencies of up to 7.7% and sky-blue emission with CIE coordinates of (0.17, 0.37) have been realized. The operational stability for the device based on complex 1 has also been explored, and the device is found to show fairly respectable lifetime. This work opens up a new avenue to the design and synthesis of blue phosphorescent emitters. PMID- 30277070 TI - Polymer Nanowires with Highly Precise Internal Morphology and Topography. AB - The construction of precise soft matter nanostructures in solution presents a challenge. A key focus remains on the rational design of functionalities to achieve the high morphological complexity typically found in biological systems. Advances in controlled polymerizations and self-assembly increasingly allow approaches toward complex hierarchical nanomaterials. By combining tailor-made cylindrical polymer brushes, block copolymers and interpolyelectrolyte complexation-driven self-assembly, we demonstrate a facile construction of uniformly compartmentalized and topographically structured polymeric nanowires in aqueous media. The approach offers a modular avenue in programming the internal morphology of polymer nanowires by varying the block copolymer composition and topology. PMID- 30277072 TI - Uncovering the Spatiotemporal Dynamics of Urban Infrastructure Development: A High Spatial Resolution Material Stock and Flow Analysis. AB - Understanding the complexity and sustainability of infrastructure development is crucial for reconciling economic growth, human well-being, and environmental conservation. However, previous studies on infrastructure's material metabolism were mainly conducted on a global or national scale, due largely to lack of more spatially refined data, and thus could not reveal the spatial patterns and dynamics on a city scale. Here, we integrated material flow analysis (MFA) and geographical information system (GIS) data to uncover the spatiotemporal patterns of the material stocks and flows accompanying the infrastructure development at a high spatial resolution for the case of Shanghai, China. From 1980 to 2010, material stocks and waste output flows of Shanghai's infrastructure system exhibited a significant increase from 83 to 561 million metric tons (Mt) and from 2 to 17 Mt, respectively. Input flows peaked in 2005 because of the economic slowdown and stepped-up policies to cool the housing market. Spatially, the center and peri-urban areas were the largest container of material stocks and biggest generator of demolition waste, while suburban areas absorbed 58%-76% of material inputs. Plans to make the city more compact will enhance the service capacity of stocks but may also increase the use of more energy and emissions intensive construction materials (e.g., steel). Prolonging the service lifetime of infrastructure through proper management and increasing the recycling and reuse rate of demolition waste are also identified as highly efficient strategies. PMID- 30277071 TI - Nanostructured Metal Hydrides for Hydrogen Storage. AB - Knowledge and foundational understanding of phenomena associated with the behavior of materials at the nanoscale is one of the key scientific challenges toward a sustainable energy future. Size reduction from bulk to the nanoscale leads to a variety of exciting and anomalous phenomena due to enhanced surface-to volume ratio, reduced transport length, and tunable nanointerfaces. Nanostructured metal hydrides are an important class of materials with significant potential for energy storage applications. Hydrogen storage in nanoscale metal hydrides has been recognized as a potentially transformative technology, and the field is now growing steadily due to the ability to tune the material properties more independently and drastically compared to those of their bulk counterparts. The numerous advantages of nanostructured metal hydrides compared to bulk include improved reversibility, altered heats of hydrogen absorption/desorption, nanointerfacial reaction pathways with faster rates, and new surface states capable of activating chemical bonds. This review aims to summarize the progress to date in the area of nanostructured metal hydrides and intends to understand and explain the underpinnings of the innovative concepts and strategies developed over the past decade to tune the thermodynamics and kinetics of hydrogen storage reactions. These recent achievements have the potential to propel further the prospects of tuning the hydride properties at nanoscale, with several promising directions and strategies that could lead to the next generation of solid-state materials for hydrogen storage applications.

AB - Making use of temperature-controlled thiation as a key operation, a simple route to 2-aminothiophenes or thieno[2,3- c]isothiazoles has been newly developed wherein the 2-aminothiophene nucleus was formed through an initial formation of thioamide followed by a 5-exo-dig addition to the tethered alkyne; however, under harsher thermal conditions, excess sulfur-transferring reagents enabled further oxidative thiation to generate the corresponding thieno[2,3- c]isothiazoles. PMID- 30277074 TI - Brightness Enhancement in Pulsed-Operated Perovskite Light-Emitting Transistors. AB - Perovskite light-emitting field-effect transistors (PeLEFETs) provide a versatile device architecture to control transport and electroluminescence properties of hybrid perovskites, enabling injection of high charge carrier density and spatial control of the radiative recombination zone. Ionic screening and organic cation polarization effects typical of metal-halide perovskites, however, critically affect PeLEFET efficiency and reliability. In this work, we demonstrate a new device operation mode based on high-frequency modulation of the applied voltages, which allows significant reduction of ionic drift/screening in methylammonium lead iodide light-emitting transistors. In optimized top contact PeLEFETs, AC operation results in brighter and more uniform electroluminescence compared to DC driven devices, whereas high-frequency modulation enables electroluminescence emission up to room temperature. PMID- 30277077 TI - Postnovo: Postprocessing Enables Accurate and FDR-Controlled de Novo Peptide Sequencing. AB - De novo sequencing offers an alternative to database search methods for peptide identification from mass spectra. Since it does not rely on a predetermined database of expected or potential sequences in the sample, de novo sequencing is particularly appropriate for samples lacking a well-defined or comprehensive reference database. However, the low accuracy of many de novo sequence predictions has prevented the widespread use of the variety of sequencing tools currently available. Here, we present a new open-source tool, Postnovo, that postprocesses de novo sequence predictions to find high-accuracy results. Postnovo uses a predictive model to rescore and rerank candidate sequences in a manner akin to database search postprocessing tools such as Percolator. Postnovo leverages the output from multiple de novo sequencing tools in its own analyses, producing many times the length of amino acid sequence information (including both full- and partial-length peptide sequences) at an equivalent false discovery rate (FDR) compared to any individual tool. We present a methodology to reliably screen the sequence predictions to a desired FDR given the Postnovo sequence score. We validate Postnovo with multiple data sets and demonstrate its ability to identify proteins that are missed by database search even in samples with paired reference databases. PMID- 30277076 TI - Chiral Control in Pentacoordinate Systems: The Case of Organosilicates. AB - Chirality at the central element of pentacoordinate systems can be controlled with two identical bidentate ligands. In such cases the topological Levi Desargues graph for all the Berry pseudorotations (BPR, max. 20) reduces to interconnected inner and outer "circles" that represent the dynamic enantiomer pair. High enough barriers of the BPR crossovers between the two circles is all what is needed to ascertain chiral integrity. This is illustrated computationally and experimentally for the organosilicates 7 and 10 that carry besides a Me (a), Et (b), Ph (c), or F (d) group two bidentate 2-(phenyl)benzo[ b]-thiophene or 2 (phenyl)naphthyl ligands, respectively. The enantiomers of tetraorganosilane precursor 9 could be separated by column chromatography. Their chiral integrity persisted on forming the silicates. CD spectra are reported for 10c. Fluoro derivative 10d is shown to have its electronegative F substituent in an equatorial position, is stable toward hydrolysis, and its enantiomers do not racemize at ambient temperatures, while those of 10c racemize slowly. PMID- 30277075 TI - Low-Cost Method Generating In Situ Anaerobic Conditions on a 96-Well Plate for Microbial Fermentation in Food Research. AB - Commercial tools and instruments have been developed for a screening study of microbial fermentation, but they are expensive and mostly confined to aerobic fermentation only. There is little development on the generation of anaerobic conditions directly on a 96-well plate. This report proposed a simple and versatile microbial fermentation system known as OVAMO that makes use of Oxyrase, vacuum, and mineral oil to generate an in situ anaerobic environment on a 96-well plate for at least 48 h. The practicality of OVAMO in anaerobic fermentation experiments used for functional food research was validated by a prebiotic screening study of different carbohydrates by Bifidobacterium longum subsp. infantis. The OVAMO system provides a less expensive but effective way to conduct a microbial fermentation screening study that requires anaerobic conditions without the need for atmospheric control by external devices.

AB - Technical biases are introduced in omics datasets during data generation and interfere with the ability to study biological mechanisms. Several normalization approaches have been proposed to minimize the effects of such biases, but fluctuations in the electrospray current during LC-MS gradients causes local and sample specific bias not considered by most approaches. Here we introduce a software named NormalyzerDE that includes a generic retention time (RT)-segmented approach compatible with a wide range of global normalization approaches to reduce the effects of time-resolved bias. The software offers straightforward access to multiple normalization methods, allows for dataset evaluation and normalization quality assessment as well as subsequent or independent differential expression analysis using the empirical Bayes Limma approach. When evaluated on two spike-in datasets the RT-segmented approaches outperformed conventional approaches by detecting more peptides (8 - 36%) without loss of precision. Furthermore, differential expression analysis using the Limma approach consistently increased recall (2 - 35%) compared to ANOVA. The combination of RT normalization and Limma was in one case able to distinguish 108% (2597 vs. 1249) more spike-in peptides compared to traditional approaches. NormalyzerDE provides widely usable tools for performing, and evaluating the outcome of, normalization and makes calculation of subsequent differential expression statistics straightforward. The program is available as a web server at http://quantitativeproteomics.org/normalyzerde.

AB - Gold(I)-catalyzed highly enantioselective intermolecular [4 + 2] cycloaddition is shown with ynones and cyclohexadiene. Various bicyclo[2.2.2]octadiene derivatives are produced in high yields (up to 99%) with good enantioselectivity (up to 96% ee). Key to the success is generation of the gem-digold terminal alkyne as a catalytic on-cycle species. As proof of the gem-digold catalysis, a positive nonlinear effect is clarified between the ee's of the ligand and the cycloadduct. PMID- 30277080 TI - Importance of assessing and adjusting for cross-study heterogeneity in network meta-analysis: a case study of psoriasis. AB - AIM: The importance of adjusting for cross-study heterogeneity when conducting network meta-analyses (NMAs) was demonstrated using a case study of biologic therapies for moderate-to-severe plaque psoriasis. METHODS: Bayesian NMAs were conducted for Psoriasis Area and Severity Index 90 response. Several covariates were considered to account for cross-trial differences: baseline risk (i.e., placebo response), prior biologic use, body weight, psoriasis duration, age, race and baseline Psoriasis Area and Severity Index score. Model fit was evaluated. RESULTS: The baseline risk-adjusted NMA, which adjusts for multiple observed and unobserved effect modifiers, was associated with the best model fit. Lack of adjustment for cross-trial differences led to different clinical interpretations of findings. CONCLUSION: Failure to adjust for cross-trial differences in NMA can have important implications for clinical interpretations when studying the comparative efficacy of healthcare interventions. PMID- 30277081 TI - Reactive oxygen species are responsible for the cell aggregation and production of pro-inflammatory mediators in phorbol ester (PMA)-treated U937 cells on gelatin-coated dishes through upregulation of autophagy. AB - PURPOSE: Our previous studies indicate that phorbol 12-myristate 13-acetate (PMA) treated U937 cells cultured on collagen I -coated dishes express lowered production of pro-inflammatory mediators in parallel through reduced Reactive oxygen species (ROS) levels. By contrast, PMA-treated U937 cells on gelatin, the denatured collagen, show enhanced production of pro-inflammatory mediators, mediated by up-regulating autophagy levels. The present study is aimed to investigate the effect of ROS levels in PMA-treated U937 cells cultured on gelatin-coated surface. MATERIAL AND METHODS: MTT assay, flow cytometric analysis of ROS and autophagy, biochemical detection of antioxidant levels, ELISA assay, and western blot were used. RESULTS: Gelatin-coating increased ROS levels in PMA treated U937 cells. Increased ROS levels are involved in the regulation of cell aggregation and the release of pro-inflammatory mediators in gelatin-coated culture. These results lead to the query about the crosstalk between the two positive regulators, the autophagy and ROS. Autophagy induction is attenuated by NAC treatment, but the treatment with autophagy inhibitor, 3-methyladenine, does not affect ROS levels, suggesting ROS are upstream of autophagy in the regulation axis of differentiated U937 cells on gelatin-coated surface. Further study confirmed that upregulation of autophagy was responsible for ROS-induced cell aggregation and production of pro-inflammatory mediators. CONCLUSION: The results suggest that gelatin-coating promotes the aggregation of PMA-treated U937 cells and the production of pro-inflammatory mediators by ROS-autophagy signaling pathway. PMID- 30277082 TI - Pharmacokinetics of new oral anticoagulants: implications for use in routine care. AB - INTRODUCTION: Since 2008, new oral anticoagulants (NOACs) have been approved for the prevention of venous thromboembolism (VTE) in patients receiving hip or knee replacement surgery, prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation (NVAF), treatment of deep vein thrombosis (DVT), and pulmonary embolism (PE). Premarketing randomized clinical trials (RCTs) of NOACs demonstrated their non-inferiority in terms of efficacy vs. warfarin (traditional oral anticoagulant - TOA), with lower risk of serious adverse drug reactions, especially cerebral hemorrhages. In clinical practice, pharmacokinetic aspects of NOACs have to be carefully taken into account to optimize the benefit risk profile of these drugs. Areas covered: An overview of major issues related to pharmacokinetics of NOACs, such as drug-drug interactions, over- and underdosage in special populations (e.g. elderly, underweight, and chronic kidney disease patients), and impact on adherence and persistence to NOACs therapy and ultimately clinical outcomes in real-world setting, is provided. Expert opinion: NOACs have been proven to be a better option than traditional anticoagulants due to better tolerability and ease of use. However, given specific pharmacokinetic characteristics, NOAC therapy has to be carefully tailored and monitored in relation to patient characteristics with the final goal of maximizing benefits and minimizing risks. PMID- 30277083 TI - Analysis of the Genotypes in a Chinese Population with Increased Hb A2 and Low Hematological Indices. AB - Increased Hb A2 is considered the most reliable hematological finding for the identification of beta-thalassemia (beta-thal) carriers. The aim of this study was to determine the underlying genetic factors associated with a high Hb A2 level in a Chinese population. Subjects were recruited from couples preparing for pregnancy who participated in the thalassemia screening program during a 2-year period. DNA analyses were used for diagnosis of beta-thal and other genetic factors. A total of 5985 adults who screened positive for beta-thal were recruited. Of these, 5933 (99.1%) were detected to have a beta-thal mutation. In the remaining 52 (0.9%) individuals without mutations involving the beta-globin gene cluster, 16 were found to have Kruppel-like factor 1 (KLF1) gene variants, and two had an alpha-globin gene triplication. There were still 34 individuals with unknown genetic factors for their raised Hb A2 values. The results of this study indicate that genetic factors other than beta-thal can rarely contribute to the elevation of Hb A2. These subjects usually have borderline microcytic red cell indices and Hb A2 values. PMID- 30277084 TI - Infliximab biosimilar CT-P13 therapy is effective in maintaining endoscopic remission in ulcerative colitis - results from multicenter observational cohort. AB - BACKGROUND: CT-P13, the first biosimilar monoclonal antibody to infliximab (IFX), has previously been confirmed to be efficacious in inducing mucosal healing in ulcerative colitis (UC) patients. The aim of this study was to evaluate the efficacy of CT-P13 therapy in maintaining mucosal healing in UC. METHODS: CT-P13 trough levels, antibody positivity, serum inflammatory markers as CRP level, fecal calprotectin at weeks 14 and 54, concomitant steroid and azathioprine therapy at the time of induction therapy and at weeks 14 and 54, previous use of anti TNF drug and the need of dose intensification as possible predictive factors for mucosal healing at week 54 were evaluated in this prospective study. RESULTS: 61 patients had already completed the 54-week treatment period. Mucosal healing was shown in 65.5 % and 62.1 %, complete mucosal healing was present in 31% and 38 % at week 14 and 54, respectively. The median values of CRP, leukocytes, thrombocytes, and albumin showed significant difference between baseline and week 54. Serum antibody positivity was proved in 6.5 % and 19.7 % of cases at week 14 and 54, respectively. CONCLUSION: Our study confirmed the long-term efficacy of CT-P13 therapy on mucosal healing in UC. PMID- 30277086 TI - Clinical Genotyping by Next Generation Sequencing Reveals a Novel, De Novo beta Globin Gene Mutation Causing Hemolytic Anemia in a Chinese Individual. AB - Abnormal hemoglobins (Hbs) are one of the most common hemoglobinopathies worldwide. Some Hb gene mutations may produce unstable, abnormal Hbs causing macrocytic hemolysis. We identified a novel, de novo deletion/frameshift mutation at nucleotide position 408 in exon 3 of the beta-globin gene (HBB: c.408delT) compound with an Hb F-associated regulatory single nucleotide polymorphism (rSNP) (rs368698783) through next generation sequencing (NGS). This beta-globin gene variant was identified in a 5-year-old Chinese girl with splenomegaly, jaundice and macrocytic, hemolytic anemia. This variant causes a new stop codon to be formed in the 3' untranslated region (3'UTR) of the HBB gene at amino acid position 158, consequently leading to a beta-sheet disruption of the last alpha helix of this abnormal beta-globin chain. We named this variant Hb Urumqi after the proband's current city of residence. PMID- 30277085 TI - The daily practice of (suspected) coeliac disease management by general practitioners: A qualitative approach. AB - BACKGROUND: General practitioners (GPs) play a crucial role in diagnosing coeliac disease (CD). However, data on GP management of (suspected) CD patients is sparse. OBJECTIVES: To provide insights into the daily practice of diagnosis, treatment, and follow-up of CD by GPs. METHODS: A qualitative study using topic list-based semi-structured in-depth interviews with Dutch GPs with more than five years' experience carried out between January and March 2017. GPs were purposively sampled. The number of GPs interviewed depended on when data saturation was reached. We applied content analysis to the semi-structured interviews. RESULTS: Seven GPs were interviewed, five of whom were female. Analysis of the interviews resulted in three main themes: 'awareness,' 'diagnostics' and 'management.' Vague gastrointestinal symptoms and diarrhoea were often mentioned as a possible presentation of CD. Antibodies were used in CD diagnosis, although some GPs would start a gluten-free diet as a first diagnostic tool. Some GPs diagnosed CD only based on positive antibodies without referring to secondary care or duodenal biopsy analysis. GPs mentioned no role for primary care physicians in the follow-up of CD and noted the important role of dieticians in CD management. CONCLUSION: The different views of GPs on how to diagnose and monitor CD could be a basis for further research to improve CD detection rate and CD care. PMID- 30277087 TI - The effects of lycopene on alloxan induced diabetic optic neuropathy. AB - AIM: To determine the effects of lycopene treatment in prevention of diabetes associated inflammatory response and oxidative stress in an experimental model. With this aim we investigated the levels of oxidative stress markers including Malondialdehyde (MDA), and total oxidative status (TOS)together with inflammatory markers including nuclear factor- kappa B (NFKB) and tumor necrosis factor alpha (TNF-alpha) and antioxidants including total glutathione (TGSH), total oxidative status (TOS) and total anti-oxidative status (TAS) levels on eye tissue. MATERIAL AND METHODS: Totally 18 albino Wistar male rats (250-280 grams) assigned into three groups, with six rats in each group as follows: healthy group (HG), control group (CG), and lycopene group (LG). The diabetes was induced with alloxan administration in rats of CG and LG. Lycopene (4 mg/kg) was administered to the rats in LG once a day for 3 months. At the end of this period, the animals were sacrificed and their eyes were enucleated for histopathological evaluations. From the tissues, MDA, GSH, TOS, TAS, TNF-alpha and NF-kappaB levels were analyzed. RESULTS: MDA, TOS, OSI, NFKB and TNF-alpha levels were significantly higher, while TGSH and TAS levels were significantly lower in CG compared with HG (p < 0.001). On the other hand in LG; MDA, TOS, OSI, NFKB and TNF-alpha levels were significantly lower, while TGSH and TAS levels were significantly higher compared with CG (p < 0.001). Regarding histopathological findings, although there was severe damage on optic nerve of rats in CG; there was only a slight damage in lycopene administered group. CONCLUSION: For the first time in literature we determined that, lycopene was significantly effective in prevention of augmented inflammation and oxidative stress on eye tissue associated with diabetes, as well as the tissue damage on optic nerve. However, studies investigating the long-term clinical effects of lycopene on diabetic individuals are warranted. PMID- 30277088 TI - Effectiveness and safety of anti-TNF in psoriatic arthritis patients in Brazil: a post-incorporation analysis. AB - AIM: Psoriatic arthritis is a chronic disease that can result in disability and decreased quality of life. MATERIALS & METHODS: A prospective cohort was conducted in Brazil. Disease activity was measured by the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Clinical Disease Activity Index (CDAI), functionality by the Health Assessment Questionnaire Disability Index (HAQ-DI) and the quality of life by the EuroQol 5D (EQ-5D). RESULTS: In total, 122 patients were included. After 6 months, a median reduction of 2.03 in the BASDAI, 7.80 in the CDAI, 0.63 in the HAQ-DI and increase of 0.12 in the EQ-5D was observed. A good clinical response was observed in 45.5% of the patients by BASDAI and 54.5% by CDAI. Higher education and better quality of life were identified as predictors of effectiveness. The most common side effects were the infections. CONCLUSION: Anti-TNF-alpha drugs were effective and safe. The incorporation of them into the Brazilian Public Health System has provided therapeutic alternatives to the treatment of psoriatic arthritis. PMID- 30277089 TI - A phase 2 study of lenalidomide and dexamethasone in previously untreated patients with chronic lymphocytic leukemia (CLL). AB - Lenalidomide has anti-tumor activity in CLL but can be complicated by tumor lysis syndrome (TLS) and tumor flare (TF). In our previous study using low-dose lenalidomide in treatment-naive CLL, TLS was averted but TF remained frequent and complete responses (CR) were rare, despite treatment to progression. The addition of dexamethasone may mitigate TF and enable lenalidomide dose escalation, achieving durable response without long-term use. In this phase 2 trial, 31 treatment-naive CLL patients received lenalidomide (target 25mg daily) plus dexamethasone for a finite 18 cycles. No patients developed TLS and TF was infrequent. Overall responses were 74.2% (CR 9.7%) and median progression-free survival 27 months. Cereblon-binding proteins IKZF1 and IKZF3 were largely downregulated, with associated increased IRF4 levels. We therefore report that lenalidomide plus dexamethasone can achieve durable responses in a subset of patients without continuing therapy until progression. Upregulation of IRF4 may contribute to anti-CLL activity of immunomodulatory agents. This trial was registered at www.clinicaltrials.gov as NCT01133743. PMID- 30277090 TI - Extracts of different pollen species and their effect on human tear fluid and an epithelial cell line. AB - PURPOSE: Hazelnut and birch pollen are known to destroy tear film components and attack ocular surface cells. We investigated further pollen species from different plant families, whether they show similar effects on human tear fluid and an epithelial cell line in vitro, to provide a broad basis for further research on pollen reactions affecting the tear film and ocular surface. MATERIALS AND METHODS: Regional pollen species from different plant families (Adoxaceae, Betulaceae, Fagaceae, Juglandaceae, Malvaceae, Oleaceae, Pinaceae, Plantaginaceae, Poaceae, Salicaceae, Sapindaceae) were collected. Their proteolytic activity was evaluated by Zymography. Human tear fluid and cells of an epithelial cell line were incubated with pollen extracts. Tear fluid was analyzed by Polyacrylamide gel electrophoresis (PAGE). Cytomorphology was assessed microscopically and cell viability by proliferation (MTS), water-soluble tetrazolium (WST-1) assay and the impedance-based xCELLigence real-time analysis (RTCA). RESULTS: Zymography revealed significant protease activity and PAGE showed the degradation of tear proteins by different pollen species. Cells incubated with pollen extracts presented dose- and time-dependent cytomorphological changes. MTS, WST-1, and RTCA revealed cytostatic as well as cytotoxic effects of pollen extracts. CONCLUSIONS: Pollen species from different plant families exert proteolytic activity and degrade human tear fluid as well as epithelial cells, which may play a crucial role in the pathogenesis of allergic and non-allergic reactions affecting the ocular surface. PMID- 30277091 TI - Grade II Sylvian fissure meningiomas without dural attachment: case report and review of the literature. AB - Sylvian fissure meningiomas (SFMs) represent a rare subgroup of nondural-based tumors arising from the meningothelial cells within the arachnoid of the Sylvian fissure. SFMs are more frequent in young males, usually manifest with seizures and display the same radiological features of meningiomas in other locations. Although the absence of dural attachment makes these tumors suitable for a complete resection, their anatomical relationships with the middle cerebral artery branches have impaired its achievement in half of them. To the best of our knowledge, only five atypical WHO grade II SFMs have been previously described. We provide a literature review of SFMs WHO grades I-II and discuss common characteristics and surgical challenges we found in a similar case.

PMID- 30277094 TI - Long-term treatment with plecanatide was safe and tolerable in patients with irritable bowel syndrome with constipation. AB - OBJECTIVE: This open-label, multi-center, fixed-dose study (NCT02706483) evaluated the long-term safety and tolerability of plecanatide for the treatment of adults with irritable bowel syndrome with constipation (IBS-C). METHODS: Safety and tolerability of once-daily plecanatide 6 mg for up to 53 weeks was assessed in patients with IBS-C who either had been enrolled in one of the phase 3 studies or were study-naive but met eligibility criteria of the double-blind studies. Safety was assessed by treatment-emergent adverse events (AEs). Patient reported questionnaires assessed overall IBS symptoms, treatment satisfaction, and desire for treatment continuation. No dose adjustments or treatment interruptions were permitted during the study. RESULTS: Of the 2272 patients enrolled, 1842 (81.1%) completed the study. AEs were experienced by 27.3%, and 4.3% discontinued due to an AE. Most AEs were mild or moderate (90.3%). The incidence of diarrhea, the most commonly reported AE, was low (6.7%), and declined in frequency over time. Diarrhea was the most common cause of AE-related withdrawals (2.7% of patients). At week 53 or end of treatment, 88.2% of patients reported "significant" or "moderate" relief, 72.4% were "very" or "quite" satisfied with treatment, and 76.6% were "very" or "quite" likely to continue treatment. CONCLUSIONS: Plecanatide 6 mg was safe and well tolerated in patients with IBS-C treated for up to 53 weeks, with an overall safety profile similar to the 12-week IBS-C studies. Patients reported high rates of relief and satisfaction with treatment, and interest in continuing therapy.

PMID- 30277096 TI - BACE inhibitors in clinical development for the treatment of Alzheimer's disease. AB - INTRODUCTION: The amyloid hypothesis of Alzheimer's disease (AD) affirms that brain accumulation of amyloid-beta (Abeta) oligomers and soluble aggregates represent the major pathological event of the disease. Several anti-Abeta small organic molecules, monoclonal antibodies and antigens were developed to interfere with Abeta production and clearance, including beta-site amyloid precursor protein cleaving enzyme (BACE) inhibitors, blocking the first enzymatic step of Abeta formation. All these approaches, including BACE inhibitors, have failed in large randomized clinical trials (RCTs) in mild-to-moderate AD, but further studies are now being carried out in patients at early AD stages and in asymptomatic subjects at risk of developing AD. Areas covered: The paper provides a comprehensive review of BACE inhibitors for AD treatment, focusing on the most advanced compounds in Phase III RCTs. Expert commentary: BACE inhibitors inhibited robustly, and dose-dependently, Abeta formation in cerebrospinal fluid of AD patients, but without cognitive, clinical, or functional benefit in large RCTs. BACE inhibition may be not sufficient to decrease brain Abeta plaques and aggregates. Indeed, several BACE inhibitors were found to be poorly tolerated and some of them failed also in patients with prodromal AD. This may indicate that blocking the formation of nascent Abeta is not useful in AD. PMID- 30277097 TI - A Novel beta-Globin Gene Mutation: Hb Shenzhen [beta90(F6)Glu->Ala, HBB: c.272A>C]. AB - We report a novel beta-globin chain variant, Hb Shenzhen [beta90(F6)Glu->Ala, HBB: c.272A>C], in a 52-year-old Chinese individual. The hemoglobin (Hb) variant takes the position of the Hb D zone using capillary electrophoresis. Sanger sequencing revealed a novel base mutation on the beta-globin gene, HBB: c.272A>C, that resulted in a transition of glutamic acid to alanine at exon 2 of the beta globin gene. We named this novel variant Hb Shenzhen for the geographic origin of this proband. PMID- 30277098 TI - Characterization of two new high-grade B-cell lymphoma cell lines with MYC and BCL2 rearrangements that are suitable for in vitro drug sensitivity studies. AB - High-grade B-cell lymphomas with MYC and BCL2 or BCL6 rearrangements are highly aggressive B-cell lymphomas called double-hit lymphomas (HGBL-DH). They are particularly refractory to standard treatments and carry a poor prognosis. Fragments of resected tumoral lymph nodes from two HGBL-DH patients were put in culture. Continuously proliferating cells were characterized and compared with the original tumors. In both cases, the proliferating cells and the tumor displayed MYC and BCL2 rearrangements. Both cell lines (called LB5848-LYMP and LB5871-LYMP) presented a high proliferation rate and were maintained in culture for more than one year. Upon injection in immunodeficient mice, LB5848-LYMP gave rise to lymphoid tumors. In vitro treatment of these cell lines with a BCL2 inhibitory drug (ABT-199) selectively stopped their proliferation. These new cell lines represent valuable tools for studying HGBL-DH and for the in vitro testing of candidate therapies targeting HGBL-DH. LB5848-LYMP is also suitable for similar experiments in vivo. PMID- 30277099 TI - Adverse events, resource use, and economic burden associated with mantle cell lymphoma: a real-world assessment of privately insured patients in the United States. AB - In view of recent therapeutic advances in mantle cell lymphoma (MCL), the aim of this retrospective cohort analysis was to assess treatment patterns, adverse events (AEs), resource utilization, and health care costs in patients with MCL in a US-based commercial claims database. A total of 783 patients with MCL (median age = 65 years) were selected. Among patients receiving systemic therapy (n = 457), the most common treatment regimens were bendamustine/rituximab (BR) (41.1%), rituximab/cyclophosphamide/doxorubicin/vincristine (RCHOP) (26.7%), rituximab monotherapy (20.4%), and ibrutinib monotherapy (14.2%). Mean monthly costs during treatments with BR, RCHOP, rituximab, and ibrutinib were $12,958, $24,719, $13,153, and $21,690, respectively. Mean monthly cost during follow-up was $13,650 among patients with >=6 AEs versus $5131 among those without AEs. The costs of MCL varied considerably by treatment regimen and care setting. The overall economic burden of managing patients with MCL can be substantially affected by costs associated with managing AEs occurring during treatment. PMID- 30277100 TI - Augmented myeloablative conditioning with thiotepa in acute myeloid leukemia - improved outcomes with similar toxicity. AB - Myeloablative doses of busulfan (Bu) with fludarabine (Flu) have reduced toxicity, however, limited by an increased relapse rate. We aimed to improve outcome of Flu-Bu regimen by augmentation with thiotepa (TT) (10 mg/kg). Eighty nine patients with AML, 44 patients conditioned with Flu-Bu (group 1), and 45 patients augmented with TT (Flu-Bu-TT, group 2), were retrospectively analyzed. Primary objectives were toxicity and outcomes. Major toxicities were comparable: mucositis (p = 1.0), sepsis (p = .7), severe venocclusive disease of liver (VOD) (p = 1.0), and non-relapse mortality (NRM) (22 vs. 22%, p = .7). Five-year disease-free survival was significantly better in group 2 compared to group 1 (62 vs. 38%, p = .02). Five-year overall survival (OS) showed trend toward benefit in group 2 (62 vs. 42%, p = .06). Lower relapse rate in group 2 (14 vs. 46%, p = .005) contributed to better outcomes. Augmented regimen has better disease-free survival (DFS) (mainly due to reduced relapse rate) and similar toxicities as compared to Flu-Bu. Key points Assessing the addition of TT to myeloablative conditioning (Flu, Bu) in patients undergoing allogeneic stem cell transplant for acute myeloid leukemia with regard to relapse rate, disease-free survival and toxicity. Addition of thiotepa improves disease-free survival and shows trend toward benefit in overall survival, by reducing relapses without additional toxicity. PMID- 30277101 TI - Characterizing the kinetics of lymphocytosis in patients with chronic lymphocytic leukemia treated with single-agent ibrutinib. AB - Increased absolute lymphocyte count (ALC) is a key feature of chronic lymphocytic leukemia (CLL) but is also observed during treatment with B-cell receptor pathway inhibitors including ibrutinib, a first-in-class inhibitor of Bruton's tyrosine kinase. In patients with CLL treated with single-agent ibrutinib in two multicenter, open-label, randomized, phase 3 studies (RESONATE-2, NCT01722487; RESONATE, NCT01578707), lymphocytosis was observed in 77 of 136 (57%) patients treated in first-line and 133 of 195 (69%) relapsed/refractory patients. On treatment, lymphocytosis resolved in 95% of patients in the first-line and 94% in the relapsed/refractory setting. The median duration of lymphocytosis was 12 and 14 weeks in the first-line and relapsed/refractory settings, respectively. Lymphocytosis is a common and predictable pharmacodynamic effect of ibrutinib treatment, and in the absence of other signs of progression, does not represent disease progression. Lymphocytosis resolves in the majority of patients and does not require interruption or discontinuation of ibrutinib therapy. PMID- 30277103 TI - The JAK inhibitor antcin H exhibits direct anticancer activity while enhancing chemotherapy against LMP1-expressed lymphoma. AB - Epstein-Barr virus (EBV) infection is associated with B cell lymphomas in humans. The latent membrane protein 1 (LMP-1) of EBV constitutively activates the JAK/STAT signaling pathway and contributes to the proliferation of EBV-infected primary human B lymphocytes. Thus, targeting LMP1-induced JAK/STAT signaling may prove effective in treating B-cell lymphomas. The extract of the fruiting body of Antrodia cinnamomea, has been reported to have cytotoxicity on blood cancer cells. Here, we report that the bioactivity of antcin H, an analog of the JAK2 inhibitor zhankuic acid A (ZAA), inhibits LMP1-induced JAK/STAT related signaling and induces lymphoma cell line apoptosis. Moreover, antcin H enhances low-dose methotrexate (MTX) cytotoxicity against lymphoma cells. Treatment of antcin H with low-dose MTX significantly suppressed tumor growth and prolonged the survival of tumor-bearing mice. Our findings indicate antcin H as a potential therapeutic agent for the treatment of EBV-infected cancer cells. PMID- 30277102 TI - Obinutuzumab plus CHOP is effective and has a tolerable safety profile in previously untreated, advanced diffuse large B-cell lymphoma: the phase II GATHER study. AB - This study investigated the safety and efficacy of obinutuzumab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (G-CHOP) in patients with advanced diffuse large B-cell lymphoma (DLBCL) and explored the impact of cell-of-origin (COO) on patient outcomes. Patients (N = 100) received obinutuzumab (1000 mg on the days 1, 8, and 15 of cycle 1, and day 1 of cycles 2 8) plus CHOP (cycles 1-6). For patients without grade >=3 infusion-related reactions (IRRs) to standard-rate obinutuzumab infusion, a shorter duration of infusion (SDI) was evaluated. Overall and complete response rates, as determined according to the Cheson et al. criteria by investigators/independent radiological facility, were 82.0/75.0% and 55.0/58.0%, respectively. SDI of 120 minutes and 90 minutes were well tolerated with no grade >=3 IRRs. Among all patients, IRRs typically occurred during cycle 1, day 1. G-CHOP is active and has an acceptable safety profile in the first-line treatment of patients with advanced DLBCL. Clinical Trials: NCT01414855DLBCL. PMID- 30277104 TI - Is there an order of loss of sounds in speakers with Parkinson's disease? AB - Influential reports on speech changes in people with Parkinson's disease (PD; Logemann et al., 1978, 1981) reported a posterior to anterior pattern of loss of speech sound accuracy. These claims have never been examined. In a partial replication of Logemann et al.'s work, we examined whether posterior lingual sounds are most affected in people with Parkinson's disease, followed by anterior lingual sounds and then labial sounds. Ninety-nine people with PD (age: mean 70.7, SD 8.46; time since diagnosis: mean 6.97, SD 6.2) with mild to severe overall motor symptoms (Hoehn and Yahr stages 1-5, median 2.5) completed a diagnostic intelligibility test. This was scored by 60 listeners unfamiliar with PD and dysarthric speech. We calculated the proportion of posterior versus anterior lingual versus labial sounds misrecognized by the listeners. We compared profiles of misperceived sounds within and across Hoehn and Yahr stages of severity and in relation to Unified Parkinson's Disease Rating Scale (UPDRS) and speech intelligibility scores. Speech accuracy declined significantly in relation to overall motor impairment for labial and anterior lingual sounds but not for velar sounds. Speech sound accuracy was strongly associated with intelligibility outcomes (p = < 0.01). Contrary to previous assertions, there was no evidence supporting the existence of a posterior to anterior order of 'loss' of oral speech sounds in people with PD, nor an interaction of anterior-posterior speech profile changes with Hoehn and Yahr stage. Findings support the notion that a common underlying impairment of movement downscaling affects all sounds similarly and simultaneously in PD from the start.

PMID- 30277105 TI - The size and depth of lesions measured by endoscopic ultrasonography are novel prognostic factors of primary gastric diffuse large B-cell lymphoma. AB - Diffuse large B cell lymphoma is one of the predominant histological subtypes of primary gastric lymphomas. Factors that contribute to precise stratification and guide the treatment of this disease are still not well understood. We analyzed 73 primary gastric diffuse large B cell lymphoma patients retrospectively, and found that patients characterized by late stage, multiple localization, B symptoms, lower serum albumin level and elevated LDH level had a shorter overall survival through Univariate Cox regression analysis. Multivariate Cox regression analysis demonstrated that ALB <= 35g/L, staging >= IIE and multiple sites localization were independent adverse prognostic factors. Significantly, in 35 patients who received endoscopy at diagnosis, Kaplan-Meier analyses indicated that patients with large (>=3 cm) and deep lesions (>=11 mm) had an inferior OS (p = .01 and .039). These findings implicated that tumor size and depth are two indicators of prognosis under ultrasonography. Further randomized studies with large number of cases are needed. PMID- 30277107 TI - FLAG salvage therapy combined with idarubicin in relapsed/refractory acute myeloid leukemia. AB - Acute myeloid leukemia (AML) is characterized by a high failure rate to achieve complete remission as well as high relapse rates that cause an emergent need for efficient and tolerable salvage therapies. The combination of FLAG with idarubicin (FLAG-Ida) is a widely used protocol. However, its efficacy has been analyzed in only a limited number of studies with majorly small patient cohorts. Here, we analyzed 132 patients with largely primary refractory or first-time relapsed AML treated according to the FLAG-Ida protocol. The overall complete remission rate (CR + CRi) was 56% with a median overall survival of 15 months (95% CI, 5.7-25.1). The median disease-free survival for CR/CRi-patients was not reached. The mortality rate on day 30 was 9% and increased on day 60 to 16%. Our results show in relapsed/refractory AML patients a high efficacy and compatibility for the FLAG-Ida regimen.

PMID- 30277108 TI - Granulocyte colony-stimulating factor and respiratory status of critically ill neutropenic patients with hematologic malignancies. AB - In patients with hematologic malignancies, respiratory status may deteriorate during neutropenia recovery. This multicenter, observational study aims to evaluate granulocyte colony-stimulating factor (G-CSF) impact on respiratory status in critically ill neutropenic patients. Among 1011 critically ill patients with hematologic malignancies, 288 were neutropenic and included in this study. 201 (70%) did not receive G-CSF at day 1 or 2. After propensity score matching for the probability of receiving G-CSF at day 1 or 2, there was no association between G-CSF and respiratory deterioration at day 14 (OR =1.19; 95%CI (0.57 2.51); p = .64). Additional sensitivity analysis in patients admitted for acute respiratory failure showed similar results (OR =1.34; 95%CI (0.5-3.59); p = .57). Among patients who recovered from neutropenia, 75% experienced respiratory deterioration during neutropenia recovery. This study confirms that neutropenia recovery is a situation at risk of respiratory deterioration. However, whether G CSF is an aggravating factor cannot be supported by our results. PMID- 30277112 TI - A comparison of patients with acute myeloid leukemia and high-risk myelodysplastic syndrome treated on versus off study. AB - Patients with newly diagnosed (ND) and relapsed/refractory (RR) acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS, >=10% blasts) often receive intensive chemotherapy at diagnosis and relapse. We retrospectively identified 365 patients and categorized the reasons for receiving treatment off study (medical, logistical, or unclear). The pretreatment characteristics of the on and off study groups were similar. Rates of the complete remission (CR) without measurable residual disease were significantly higher for ND patients treated on versus off study (61% versus 35%), but CR rates and survival were low for all RR patients regardless of study assignment. The subset of ND patients treated off study for medical reasons had significantly decreased overall survival and relapse-free survival. Standard, stringent study eligibility criteria may delineate a population of ND, but not RR, patients with improved outcomes with intensive induction chemotherapy. PMID- 30277110 TI - Efficacy of salvage chemotherapy in diffuse large B cell lymphoma with primary treatment failure according to putative cell of origin. AB - We evaluated outcome of 235 primary treatment failure (PTF) diffuse large B-cell lymphoma (DLBCL) patients based on salvage chemotherapy regimen and putative cell of-origin (COO). Patients were divided into two groups; group A (n = 38) received high-dose cytarabine containing regimen, either DHAP or ESHAP. Patients in group B (n = 197) received ifosfamide, carboplatin, and etoposide (ICE) +/- rituximab. No difference in overall response rates (CR + PR) was observed based on salvage chemotherapy regimen and COO. After adjustment for the presence of ultra high risk features, overall survival of germinal center B-cell like (GCB) DLBCL patients in group A was not significantly different from survival in group B (HR 0.86, 95% CI 0.46-1.60, p = .64). Similarly, within non-GCB DLBCL cohort, survival in group A was comparable to group B (HR 0.53, 95% CI 0.20-1.44, p = .21). We did not find an outcome difference between two commonly used salvage chemotherapy regimens in patients with PTF DLBCL based on COO. PMID- 30277111 TI - Elderly acute lymphoblastic leukemia: a Mayo Clinic study of 124 patients. AB - Poor outcomes in elderly acute lymphoblastic leukemia (ALL) are well recognized, but the contributors are ill-defined. We characterized 124 patients >=60 years old at our institution. The majority (n = 102, 82%) were treated with intensive chemotherapy. Of these, 8/102 (8%) died within the first 100 days; 92/102 (90%) achieved complete remission (CR/CRi). Only 31/124 (25%) patients underwent allogeneic hematopoietic stem cell transplantation. The median overall survival (OS) for the entire cohort was 19.8 months. In a multivariate analysis, ECOG performance status >=2, high white blood cell count, and high lactate dehydrogenase (at time of diagnosis) negatively influenced OS (p<.01). In a subgroup analysis of the intensive treatment group, BCR-ABL1+ patients had markedly better OS (hazard ratio 0.3, 95% CI 0.1-0.7; p<.01). In summary, despite few early deaths and a high CR/CRi rate, elderly ALL continues to have a poor prognosis, underscoring the need for more effective therapies. PMID- 30277113 TI - Changes in the inflammatory and oxidative stress markers during a single hemodialysis session in patients with chronic kidney disease. AB - BACKGROUND: Cardiovascular disease (CVD) is a common cause of morbidity and mortality in end-stage renal disease (ESRD) patients on hemodialysis (HD) among whom it is 5-20 times higher than in the general population. Some of the nontraditional risk factors such as oxidative stress and inflammation are related to the progress of CVD in HD patients. Several, but not all studies, reported that inflammatory and oxidative stress markers are increased during a single session of HD, mimicking changes that occur during acute immune activation. This study was taken up to evaluate the changes in the inflammatory and oxidative stress markers during a single HD session in patients with chronic kidney disease. METHODS: Twenty-five ESRD patients on maintenance HD and 25 controls were included in the study. Blood samples were obtained from the patients before starting of hemodialysis (pre-HD) and after completion of hemodialysis (post-HD). The changes in serum Pentraxin-3, hs-CRP, malondialdehyde (MDA) and ferric reducing ability of plasma (FRAP) levels were measured in pre- and post-HD ESRD patients and compared with healthy control group. RESULTS: This study found increased levels of Pentraxin-3, hs-CRP, MDA, and decreased level of FRAP in HD patients compared to controls. CONCLUSIONS: Hemodialysis procedure contributes to inflammation and oxidative stress. PMID- 30277115 TI - Panoramic view of common fusion genes in a large cohort of Chinese de novo acute myeloid leukemia patients. AB - Fusion genes are major molecular biological abnormalities in hematological malignancies. This study aimed to depict the common recurrent gene-fusion landscape in acute myeloid leukemia (AML). 3135 de novo AML cases were enrolled and 36 recurrent fusion genes were assessed using multiplex-nested RT-PCR. Twenty three distinct fusion genes were detected in 1292 (41.21%) cases. The incidence of fusion genes was higher in pediatric AML than in adult cases. The pediatric patients had higher incidences of RUNX1-RUNX1T1, KMT2A-MLLT3, KMT2A-MLLT10, KMT2A MLLT11, KMT2A-MLLT6, and FUS-ERG, whereas KMT2A-PTD was more common in adult patients. The occurrence of molecular abnormalities involving the KMT2A gene and CBFB-MYH11 was lower in Chinese pediatric AML compared to Western reports. The incidence of RUNX1-RUNX1T1 was higher in both pediatric and adult patients in our study than in Western countries. This study provides a genetic landscape of common fusion genes in Chinese AML and confirms different incidences between age groups and races. PMID- 30277114 TI - Methylation of imprinted IGF2 regions is associated with total, visceral, and hepatic adiposity in postmenopausal women. AB - Excess body fat, especially intra-abdominal fat, is a leading risk factor for metabolic diseases. Differentially methylated regions (DMRs) of two imprinted genes, insulin-like growth factor 2 (IGF2) and H19, have been associated with obesity due to their important roles in regulating body composition, but have not been examined in relation to intra-abdominal fat depots. Total body fat from whole-body dual energy X-ray absorptiometry and visceral and liver fat contents from abdominal magnetic resonance imaging in 48 healthy women aged 60-65 years (of White or Japanese ancestry) were each regressed on circulating leukocyte DNA methylation levels of IGF2 (at DMR0, DMR2a, and DMR2b) and H19 (at CTCF3) as assessed by pyrosequencing, while adjusting for age and race/ethnicity. Total fat mass was inversely associated with methylation levels of IGF2 DMR2b (P = 0.016). Total fat-adjusted visceral fat area (P = 0.062) and percent visceral fat measured at L4-L5 (P = 0.045) were associated with higher methylation levels of IGF2 DMR2b. Both total fat-adjusted percent liver fat (P = 0.039) and the presence of fatty liver (P = 0.015) were positively associated with IGF2 DMR2a methylation. Methylation levels of H19 CTCF3 were not associated with overall or intra/abdominal adiposity. The findings indicate that methylation levels of IGF2 DMR regions in leukocytes are associated with total body fat and with fat distribution in the viscera and liver independently of total adiposity.

PMID- 30277117 TI - Cytotoxic effect caspase activation dependent of a genetically engineered fusion protein with a CD154 peptide mimetic (OmpC-CD154p) on B-NHL cell lines is mediated by the inhibition of bcl-6 and YY1 through MAPK p38 activation. AB - The interaction between CD40, and its ligand, CD154, is essential for the development of humoral and cellular immune responses. The selective inhibition or activation of this pathway forms the basis for the development of new therapeutics against immunologically based diseases and malignancies. We are developing a gene fusion of Salmonella typhi OmpC protein expressing the CD154 Tyr140-Ser-149 amino acid strand. This OmpC-CD154 binds CD40 and activates B cells. In this study, we demonstrate that OmpC-CD154p treatment inhibits cell growth, proliferation and induced apoptosis in the B-NHL cell lines Raji and Ramos. The Bcl-2 family proteins were regulated and the Bcl-6 and YY1 oncoproteins were inhibited. p38 MAPK activation is an important mechanism underlying the effect on proliferation and apoptosis mediated by this fusion protein. This study establishes a basis for the possible use of fusion protein OmpC-CD154 as an alternative treatment for B-NHL. PMID- 30277118 TI - Xylella fastidiosa subsp. pauca and fastidiosa colonize Arabidopsis systemically and induce anthocyanin accumulation in infected leaves. AB - The bacterium Xylella fastidiosa is multi-host pathogen that affects perennial crops such as grapevine, sweet orange, and olive tree worldwide. It is inherently difficult to study these pathosystems owing to the long-term growth habit of the host plant. Thus, the availability of model plants becomes essential to accelerate discoveries with economic impact. In this study, we uncovered evidence that the model plant Arabidopsis thaliana can be colonized by two different Xylella fastidiosa subspecies, pauca and fastidiosa. We observed that these bacteria are able to move away from the inoculation point as high bacterial populations were found in distant tissues. In addition, confocal laser scanning microscopy analysis of bacterial movement inside the petiole revealed the ability of the bacterium to move against the net xylem flow during the time course of colonization forming biofilm. These findings provide evidence for the capacity of X. fastidiosa to colonize Arabidopsis. Furthermore, leaves inoculated with X. fastidiosa showed a significant accumulation of anthocyanin. We propose that the X. fastidiosa subsp. pauca or fastidiosa colonization pattern and anthocyanin accumulation in the Arabidopsis ecotype Col-0 can be used as marker phenotypes to facilitate further studies aimed at improving genetic components involved in X. fastidiosa-host interaction. PMID- 30277119 TI - Genome-wide association studies identified resistance loci to orange rust and yellow leaf virus diseases in sugarcane (Saccharum spp.). AB - Sugarcane (Saccharum spp.) supplies globally ~ 80% of table sugar and 60% of bio ethanol. Sugarcane orange rust and sugarcane yellow leaf virus (SCYLV) are major sugarcane diseases, causing up to 50% and 40% yield losses respectively. Sugarcane cultivars resistant to these diseases are needed to sustain sugarcane production in several regions. Dissecting DNA sequence variants controlling disease resistance provides a valuable tool for fulfilling a breeding strategy to develop resistant cultivars. In this study, we evaluated disease reactions to orange rust and SCYLV of a sugarcane diversity panel in repeated trials. We conducted a genome-wide association study between high-density markers and disease-resistance reactions. We identified 91 putative DNA markers and 82 candidate genes significantly associated with resistance to one of the two diseases. These provide an important genetic resource for finding genes and molecular markers for disease resistance. Our results emphasized the importance of utilizing a wide germplasm collection for breeding resistant sugarcane cultivars. PMID- 30277120 TI - The incidence of bleomycin induced lung toxicity is increased in Hodgkin lymphoma patients over 45 years exposed to granulocyte-colony stimulating growth factor ?. AB - In Hodgkin lymphoma (HL) bleomycin can induce pulmonary toxicity (BPT). BPT consists of respiratory tract symptoms during bleomycin-exposure and radiologic pulmonary lesions without concomitant infection. Older age, bleomycin dose, smoking history and the use of granulocyte-colony stimulating factor (G-CSF) have been suggested as possible risk factors for BPT. It is still debated whether BPT affects overall (OS) and progression-free survival (PFS). We investigated the incidence of BPT along with possible risk factors in 412 HL patients treated in 1990-2014. BPT occurred in 34 patients (8%) and was significantly associated with disseminated disease and B-symptoms. It was more frequent in elderly patients (p = .05) but not significantly correlated with a history of smoking. BPT occurred more often in patients receiving G-CSF (p = .03), particularly the poly ethylenglycol-bound molecule. All significant risk correlations were limited to the age group >45 years. In the present cohort, BPT did not influence OS or PFS regardless of age. PMID- 30277121 TI - Twelve tips for responding to microaggressions and overt discrimination: When the patient offends the learner. AB - Microaggressions and expressions of overt discrimination negatively affect the experience of medical trainees at all levels. Mistreatment of trainees, including abusive and discriminatory behavior by patients and families, occurs commonly and is receiving increased attention in both the medical literature and popular press. Heightened awareness of the problem has sparked a call to engage in substantive conversations about bias in health professions education. The emphasis on direct observation in medical education makes the bedside a common setting for educators to witness these behaviors firsthand. Many educators are committed to developing a positive climate for learners but lack the training and skills to facilitate discussions about discrimination. As a result, these difficult but important conversations may not occur. The authors present a three phase approach to responding to microaggressions and discrimination toward trainees from patients, and offer a communication toolkit that frontline medical educators can use in their daily practice.

PMID- 30277122 TI - Research articleHemolysis in human erythrocytes by Clostridium perfringens epsilon toxin requires activation of P2 receptors. AB - Epsilon-toxin (ETX) is produced by types B and D strains of Clostridium perfringens, which cause fatal enterotoxaemia in sheep, goats and cattle. Previous studies showed that only a restricted number of cell lines are sensitive to ETX and ETX-induced hemolysis has not previously been reported. In this study, the hemolytic ability of ETX was examined using erythrocytes from 10 species including murine, rabbit, sheep, monkey and human. We found that ETX caused hemolysis in human erythrocytes (HC50 = 0.2 MUM) but not erythrocytes from the other test species. Moreover, the mechanism of ETX-induced hemolysis was further explored. Recent studies showed that some bacterial toxins induce hemolysis through purinergic receptor (P2) activation. Hence, the function of purinergic receptors in ETX-induced hemolysis was tested, and we found that the non selective P2 receptor antagonists PPADS inhibited ETX-induced lysis of human erythrocytes in a concentration-dependent manner, indicating that ETX-induced hemolysis requires activation of purinergic receptors. P2 receptors comprise seven P2X (P2X1-7) and eight P2Y (P2Y1, P2Y2, P2Y4, P2Y6, and P2Y11-P2Y14) receptor subtypes. The pattern of responsiveness to more selective P2-antagonists implies that both P2Y13 and P2X7 receptors are involved in ETX-induced hemolysis in human species. Furthermore, we demonstrated that extracellular ATP is likely not involved in ETX-induced hemolysis and the activation of P2 receptors. These findings clarified the mechanism of ETX-induced hemolysis and provided new insight into the activities and ETX mode of action.

PMID- 30277126 TI - Association between AXL promoter methylation and lung function growth during adolescence. AB - AXL is one of the TAM (TYRO3, AXL and MERTK) receptor tyrosine kinases and may be involved in airway inflammation. Little is known about how epigenetic changes in AXL may affect lung development during adolescence. We investigated the association between AXL DNA methylation at birth and lung function growth from 10 to 18 years of age in 923 subjects from the Children's Health Study (CHS). DNA methylation from newborn bloodspots was measured at multiple CpG loci across the regulatory regions of AXL using Pyrosequencing. Linear spline mixed-effects models were fitted to assess the association between DNA methylation and 8-year lung function growth. Findings were evaluated for replication in a separate population of 237 CHS subjects using methylation data from the Illumina HumanMethylation450 (HM450) array when possible. A 5% higher average methylation level of the AXL promoter region at birth was associated with a 48.4 ml decrease in mean FEV1 growth from 10 to 18 years of age in the primary study population (95% CI: -100.2, 3.4), and a 53.9 ml decrease in mean FEV1 growth from 11 to 15 years of age in the replication population (95% CI: -104.3, -3.5). One CpG locus in the promoter region, cg10564498, was significantly associated with decreased growth in FEV1, FVC and MMEF from 10 to 18 years of age and the negative associations were observed in a similar age range in the replication population. These findings suggest a potential association between AXL promoter methylation at birth and lower lung function growth during adolescence. PMID- 30277127 TI - Health risk due to chronic heavy metal consumption via cow's milk produced in Puebla, Mexico, in irrigated wastewater areas. AB - The aim of this study was to determine the heavy metals content of milk from cows fed with forage irrigated with waste water from industrial sources and the health risk to children. Milk samples were taken from milk collection tanks of eight localities in the state of Puebla. On average, the heavy metals in the milk had the following order Zn> As> Pb > Cr> Cu > Ni. Pb (0.03 mg kg-1) exceeded the Codex limits. For As the hazard index was 8.0 +/- 0.4, which is far above 1. On the other hand, the individual risk of cancer showed a descending order Cr> As > Pb, while the risk of total cancer (0.004 +/- 0.002) indicated that the combined effect of heavy metals created a serious risk for girls and children. PMID- 30277128 TI - Mesenchymal stem cells in myeloproliferative disorders - focus on primary myelofibrosis. AB - Primary myelofibrosis (PMF) is the most aggressive Philadelphia-negative (Ph-) myeloproliferative neoplasm (MPN), characterized by bone marrow (BM) insufficiency, myelofibrosis (MF), osteosclerosis, neoangiogenesis, and extramedullary hematopoiesis (EMH) in spleen and liver. Presently, there is no curative treatment for this disease and therapy consists primarily of symptom relief and, in selected cases, allogeneic hematopoietic stem cell transplant (alloHSCT). PMF's major defining characteristics, as well as several recently described aspects of its cellular and molecular pathophysiology all support a critical role for dysregulated cell-cell/cell-extracellular matrix interactions and cytokine/chemokine signaling within the BM niche in the natural history of this disease. This review will highlight current data concerning the involvement of the BM niche, particularly of mesenchymal stem cells (MSC), in PMF, and will then discuss the rationale for a stroma-directed treatment, and the advantages such an approach would offer over the current treatments focused on targeting the malignant clone.

PMID- 30277131 TI - IL-10 is overexpressed in human cutaneous T-cell lymphoma and is required for maximal tumor growth in a mouse model. AB - A crucial question pertains to a role of IL-10 as a tumorigenic factor, or just a marker of advanced disease in cutaneous T-cell lymphoma (CTCL). Herein, we measured significantly elevated IL-10 mRNA in a cohort of skin samples of patients with CTCL. Increased IL-10 was also detected in the tumor microenvironment of an established inflammation-dependent murine model of using MBL2 T lymphoma cells. Conditioned media from MBL2 cells was able to stimulate IL 10 production in bone marrow-derived macrophages in an IL-4-dependent manner. Implanted MBL2 T-cell lymphomas in IL-10KO mice were 50% smaller, accompanied by decreased numbers of infiltrating macrophages and reduced efficiency of M2 polarization compared with wild-type mice. With anti-IL-10R mAb treatment, both wild-type tumor-bearing mice and IL-10KO mice exhibited a further growth inhibition. Our data indicate that targeting IL-10 signaling with neutralizing antibodies to IL-10 or its receptor may have a great potential for advanced CTCL therapy.

AB - Recently greater emphasis has been given to combination therapy for generating synergistic effects of treating cancer. Recent studies on thiol-sensitive nanocarriers for the delivery of drug or gene have shown promising results. In this review, we will examine the rationale and advantage in using nanocarriers for the combined delivery of different anticancer drugs and biologics. Here, we also discuss the role of nanocarriers, particularly redox-sensitive polymers in evading or inhibiting the efflux pump in cancer and how they modulate the sensitivity of cancer cells. The review aims to provide a good understanding of the new pattern of cancer treatment and key concerns for designing nanomedicine of synergistic combinations for cancer therapy. PMID- 30277133 TI - Bioformulative concepts on intracellular organ specific bioavailability. AB - Bioavailability is an ancient but effective terminology by which the entire therapeutic efficacy of a drug directly or indirectly relays. Despite considering general plasma bioavailability, specific organ/tissue bioavailability will pave the path to broad spectrum dose calculation. Clear knowledge and calculative vision on bioavailability can improve the research and organ-targeting phenomenon. This article comprises a detailed introduction on bioavailability along with regulatory aspects, kinetic data and novel bioformulative approaches to achieve improved organ specific bioavailability, which may not be readily related to blood plasma bioavailability. PMID- 30277134 TI - Sodium alginate capsulation increased brain delivery of probucol and suppressed neuroinflammation and neurodegeneration. AB - AIM: To enhance the bioavailability and brain uptake of probucol and examine whether it attenuates neuroinflammation and neurodegeneration by utilizing a sodium alginate nanoencapsulation technique. MATERIALS & METHODS: Wild-type mice were given either low-fat standard chow, high-fat (HF) diet to induce neuroinflammation and neurodegeneration, HF diet supplemented with nanocapsuled probucol at a concentration of 0.1% (w/w), HF diet supplemented with noncapsulated probucol at the same concentration of 0.1%, or HF diet supplemented with noncapsulated probucol at higher concentration (1%) for 24 weeks. RESULTS & CONCLUSION: The nanoencapsulation increased the plasma and brain concentration of probucol significantly compared with the mice that was given the same dosage of probucol without capsulation, and significantly suppressed the neuroinflammation and neurodegeneration.

AB - AIM: Tacrolimus (TAC) is an important drug for inflammatory diseases. However, TAC has several limitations, such as variable trough concentrations among individuals and a high medication frequency. In this study, we created NK61060, a novel micellar TAC formulation, to circumvent these disadvantages. MATERIALS & METHODS: Immunosuppressive activity of NK61060 was determined in the collagen induced arthritis rat model, mannan-induced arthritis mouse model and dextran sodium sulfate-induced colitis mouse model. The pharmacokinetics and toxicology of NK61060 were evaluated in those models. RESULTS: In arthritis and colitis models, NK61060 exhibited superior immunosuppressive activity compared with that of TAC. Pharmacokinetic and toxicological analyses indicated that NK61060 had a wider safety margin and could be administered at a reduced medication frequency. CONCLUSION: NK61060 mitigates the trough concentration variability and the medication frequency and it may be a safer and more effective option for use in clinical settings. Further studies are needed to determine its clinical usefulness. PMID- 30277137 TI - Emerging therapeutic nanotechnologies in pancreatic cancer: advances, risks and challenges.

PMID- 30277139 TI - Preface. PMID- 30277140 TI - Systematic review on anti-diabetic properties of chalcones. AB - The use of anti-diabetic drugs has been increasing worldwide and the evolution of therapeutics has been enormous. Still, the currently available anti-diabetic drugs do not present the desired efficacy and are generally associated with serious adverse side effects. Thus, entirely new interventions, addressing the underlying etiopathogenesis of type 2 diabetes mellitus, are required. Chalcones, secondary metabolites of terrestrial plants and precursors of the flavonoids biosynthesis, have been used for a long time in the traditional medicine due to their wide-range of biological activities, from which the anti-diabetic activity stands out. This review systematizes the information found in literature about the anti-diabetic properties of chalcones, in vitro and in vivo. Chalcones are able to exert these properties by acting in different therapeutic targets: dipeptidyl peptidase 4 (DPP-4); glucose transporter type 4 (GLUT4), sodium glucose cotransporter 2 (SGLT2), alpha-amylase, alpha-glucosidase, aldose reductase (ALR), protein tyrosine phosphatase 1B (PTP1B), peroxisome proliferator activated receptor-gamma (PPARgamma) and adenosine monophosphate (AMP)-activated protein kinase (AMPK). Chalcones are, undoubtedly, promising anti-diabetic agents, and some crucial structural features as already been established. From the structure-activity relationships analysis, it can generally be stated that the presence of hydroxyl, prenyl and geranyl groups in their skeleton improves their activity on the evaluated antidiabetic targets. PMID- 30277141 TI - Bio-polymer Substrates in Buccal Drug Delivery: Current Status and Future Trend. AB - BACKGROUND: This paper provides a critical review of biopolymer-based substrates, especially the cellulose derivatives, for their application in buccal drug delivery. Drug delivery to the buccal mucous has the benefits of immobile muscle, abundant vascularization and rapid recovery, but not all the drugs can be administered through the buccal mucosa (e. g., macromolecular drugs), due to the low bioavailability caused by their large molecular size. This shortfall inspired the rapid development of drug-compounding technologies and the corresponding usage of biopolymer substrates. METHODS: Cellulose derivatives have been extensively developed for drug manufacturing to facilitate its delivery. We engaged in structured research of cellulose-based drug compounding technologies. We summarized the characteristic cellulose derivatives which have been used as the biocompatible substrates in buccal delivery systems. The discussion of the potential use of the rapidly-developed nanocellulose (NC) is also notable in this paper. RESULTS: Seventy-eight papers were referenced in this perspective paper with the majority (sixty-five) published later than 2010. Forty-seven papers defined the buccal drug delivery systems and their substrates. Fifteen papers outlined the properties and applications of cellulose derivatives. Nanocellulose was introduced as a leading edge of nanomaterial with sixteen papers highlighted its adaptability in drug compounding for buccal delivery. CONCLUSION: The findings of this perspective paper proposed the potential use of cellulose derivatives, the typical kind of biopolymers, in the buccal drug delivery system for promoting the bioavailability of the macromolecular drugs. Nanocellulose (NC) in particular was proposed as an innovative bio-binder/carrier for the controlled release of drugs. PMID- 30277142 TI - A Review: The Anti-inflammatory, Anticancer, Antibacterial Properties of Four Kinds of Licorice Flavonoids Isolated from Licorice. AB - Plants have always been an important source of medicines for humans, and licorice is a very significant herb in the development of humans. As a traditional herb, it is widely cultivated in China, Japan, Russia, Spain, and India. With the development of organic chemistry and biochemistry, various chemical ingredients extracted from licorice have been studied and identified. Among them, many chemical components were considered to have strong pharmacological activities, such as anti-inflammatory, anti-ulcer, antibacterial, anticancer and so on. Based on those reports, licorice has attracted the attention of many researchers in recent years, and they are devoted to discovering the active ingredients and mechanism of action of active compounds. Licorice flavonoids are one of the main extracts of licorice root and stem, and has many potential biological properties. This paper aims to summarize the four kinds of licorice flavonoids, including liquiritigenin, isoliquiritigenin, licochalcone (including licochalcone A and licochalcone B) and glabridin, about their biological activities of anti inflammatory, anticancer, antibacterial.

OBJECTIVE: In this review article, we have discussed the recent findings on the molecular aspects of cordycepin interactions with its recognized cellular targets, and possible mechanisms of its anticancer activity. METHOD: We have explored databases like pubmed, google scholar, scopus and web of science for the update information on cordycepin and mechanisms of its anticancer activity, and reviewed in this study. RESULTS: Cordycepin has been widely recognized for its therapeutic potential against many types of cancers by various mechanisms. More specifically, cordycepin can induce apoptosis, resist cell cycle and cause DNA damage in cancer cells, and thus kill or control cancer cell growth. Also cordycepin can induce autophagy and modulate immune system. Furthermore, cordycepin also inhibits tumor metastasis. Although many success stories of cordycepin in anticancer research in vitro and in animal model, and there is no successful clinical trial yet. CONCLUSION: Ongoing research studies have reported highly potential anticancer activities of cordycepin with numerous molecular mechanisms. The in vitro and in vivo success of cordycepin in anticancer research might influence the clinical trials of cordycepin, and this molecule might be used for development of future cancer drug. PMID- 30277144 TI - Flavonoids as P-gp inhibitors: a systematic review of SARs. AB - P-glycoprotein, also known as ABCB1 in the ABC transporter family, confers the simultaneous resistance of metastatic cancer cells towards various anticancer drugs with different targets and diverse chemical structures. The exploration of safe and specific inhibitors of this pump has always been the pursuit of scientists for the past four decades. Naturally occurring flavonoids as benzopyrone derivatives were recognized as a class of nontoxic inhibitors of P gp. The recent advent of synthetic flavonoid dimer FD18, as a potent P-gp modulator in reversing multidrug resistance both in vitro and in vivo, specifically targeted the pseudodimeric structure of the drug transporter and represented a new generation of inhibitors with high transporter binding affinity and low toxicity. This review concerned the recent updates on the structure activity relationships of flavonoids as P-gp inhibitors, the molecular mechanisms of their action and their ability to overcome P-gp-mediated MDR in preclinical studies. It had crucial implications on the discovery of new drug candidates that modulated the efflux of ABC transporters and also provided some clues for the future development in this promising area. PMID- 30277145 TI - Insight into T-type calcium channel structure, function and modulation. AB - Low voltage-activated (LVA) T-type calcium channels are characterized by transient current and low threshold spikes (LTS), which in turn triggers neuronal firing and oscillatory behavior. Combined with their preferential localization in dendrites and their specific "window current", T-type calcium channels are considered to be key players in signal amplification and synaptic integration. Assisted by the developing pharmacological tools, the structural determinants in channel gating and kinetics, as well as novel physiological and pathological functions of T-type calcium channels are rapidly being uncovered. In this review, we provide an overview of structural determinants in T-type calcium channels, their involvement in disorders and diseases, the development of novel channel modulators, as well as structure-activity relationship (SAR) studies that lead to rational drug design. PMID- 30277146 TI - Autologous blood for conjunctival autograft fixation in primary pterygium surgery: A systematic review and meta-analysis. AB - OBJECTIVE: To perform a systematic review and meta-analysis of randomized controlled trials comparing the efficacy and complications of autologous blood versus using fibrin glue and surgical sutures for conjunctival autograft fixation in primary pterygium surgery. DESIGN: Systematic review with quantitative meta analysis. METHODS: Four authentic databases have been searched using relevant keywords. Eligible studies were obtained, and their data were extracted into an online form. Analysis was done using Review Manager for windows. Dichotomous outcomes were reported as risk ratio, while continuous data were reported as mean difference. RESULTS: Seven studies were included in the analysis. Most of included studies were of moderate quality according to Cochrane Risk of Bias assessment tool. There was no difference between the three techniques in recurrence rates (Risk Ratio (RR) 0.80, 95% CI [0.45 to 1.44], p= 0.46). Graft retraction and displacement were more profound in the autologous blood group vs fibrin glue and suture groups (RR 3.22, 95% CI [1.48 to7.02], p= 0.003) and (RR 5.27, 95% CI [2.24 to 12.38], p> 0.001) respectively. In terms of operative time, fibrin glue took shorter while suturing took longer time compared to blood coagulum (Mean Difference (MD) =1.57, 95% CI [0.90, 2.25], p> 0.00001) and (MD 20.47, 95% CI [-38.05 to -2.88], p =0.02). CONCLUSIONS: Autologous blood for conjunctival autograft fixation in primary pterygium surgery was associated with lower graft stability than fibrin glue or sutures. However, it did not account for higher recurrence rates than the fibrin glue or sutures. Patient satisfaction and postoperative symptoms are relatively better in the blood coagulum group than the other techniques. The overall quality of evidence is low. Further well designed randomized controlled trials are still needed. PMID- 30277147 TI - Complementary functional strategy for modulation of human gut microbiota. AB - BACKGROUND: Two pathologies commonly associated with gut microbiota dysbiosis are type 2 diabetes and cardiovascular diseases. A disturbance in microbial balance translates into the occurrence of degenerative dysfunctions that are also associated with other pathologies, such as obesity, colon cancer. METHODS: Thus, the aim of this review was to present the significant findings related to human microbiome modulation via the prebiotic effects of wild edible mushrooms as a complementary strategy to modern treatment. RESULTS: Since diet and medication are two important causes of microbiome fingerprint modifications, new complementary and alternative methods can include wild edible mushrooms, which serve as functional products, given their properties in modulating the microbial pattern at the colon level. The metagenomic study has enabled the identification of some competitive microbiological and biochemical biomarkers which allow the development of innovative strategies in controlling microbial disbalance from human gut. CONCLUSION: Certain mushroom species have been approaching and their effects on the microbiota fingerprint of two major target groups are highlighted. PMID- 30277148 TI - Current status on the effect of diterpenes on hepatic system. AB - BACKGROUND: Complication in the hepatic system is a major concern for human being. To control and keep the hepatic system healthy, a number of measures, including drug treatments are considered. Diterpenes are essential oils have promising antioxidant and cytotoxic properties along with their genotoxic and mutagenic effects. These agents are good targets for health promotion, especially in the light of their potential of organo-protectivity. METHODS: We searched in the databases, PUBMED and SCIENCE DIRECT from June 2011 to June 2016 for publishing evidence on diterpenes and their effects on hepatic system. After sorting the data, activity-wise findings are discussed in this current article. RESULTS: The results suggest that diterpenes have hepatoprotectivity property via antioxidant and anti-inflammatory, antimicrobial, anticancer/antitumor, hypolipidemic, anti-apoptosis, autophagic, anti-metastasize, anti-proliferating, anti-fibrosis as well as receptor and serum biomarkers mediated pathways. On the other hand, hepatoxic effects of diterpenes are also accounted with cytotoxicity, apoptotic cell death and down-regulatory effects on cytochrome P450 systems. CONCLUSION: A number of important diterpenes have been reported in the literatures that act on the hepatic system. Some of them exert toxic effects on the liver, especially in rodent model. Hence, more extensive researches are recommended that will highlight their mechanism of action on the liver. PMID- 30277149 TI - Protective mechanisms of Butyrate on Inflammatory Bowel Disease. AB - Inflammatory bowel disease (IBD) is a multifactorial chronic disease, commonly associated with alteration in the composition and function of gut microbiota. This process can lead to a decreased production of short chain fatty acids (SCFAs) by the gut microbiota, mainly butyrate, which is an important immunomodulatory molecule in the intestine. Butyrogenic bacteria normally produces butyrate through carbohydrate fermentation or amino acids degradation pathways. This molecule plays an important protective role in intestinal homeostasis acting in both adaptive immunity and innate immunity. This review summarizes the current knowledge about the role of butyrate on the development of IBD and the protective mechanisms of this metabolite on the intestinal mucosa and the whole body, as reported by in vitro and in vivo studies. Thus, butyrate can regulate the activation of regulatory T cells, increasing the acetylation of histones and decreasing the activation of NF-kappaB. In addition, it can also stimulate the mucus production from epithelial cells and the rearrangement of tight junction proteins. PMID- 30277150 TI - A survey for predicting enzyme family classes using machine learning methods. AB - Enzymes are proteins that act as biological catalysts to speed up cellular biochemical processes. According to their main Enzyme Commission (EC) numbers, enzymes are divided into six categories: EC-1: oxidoreductase; EC-2: transferase; EC-3: hydrolase; EC-4: lyase; EC-5: isomerase and EC-6: synthetase. Different enzymes have different biological functions and acting objects. Therefore, knowing which family an enzyme belongs to can help infer its catalytic mechanism and provide information about the relevant biological function. With the large amount of protein sequences influxing into databanks in the post genomics age, the annotation of family for an enzyme is very important. Since the experimental methods are cost ineffective, bioinformatics tool will be a great help for accurately classifying the family of the enzymes. In this review, we summarized the application of machine learning methods in the prediction of enzyme family from different aspects. We hope that this review will provide insights and inspirations for the researches on enzyme family classification. PMID- 30277151 TI - Alzheimer's Disease: Physical Activities as an Effective Intervention Tool - A Mini-Review. AB - BACKGROUND: There are a few risk factors which definitely have an impact on the development of Alzheimer's disease (AD). Those include genetics, gender, age, diabetes, head injuries, and lifestyle. Physical activity together with healthy diet is part of people's lifestyle. At present there exist several research studies showing that the physical activities can be a good intervention tool in the delay of cognitive decline in AD. OBJECTIVE: The aim of this study is to discuss a relationship between the physical activities and the delay and/or maintenance of cognitive decline in AD and the types of physical activities which are especially suitable for this delay. METHODS: The method of this review study consists of a method of literature review analysing the data contained in the world's prestigious scientific databases: PubMed, Springer, Web of Science and Scopus in the period of 2010 - 2015. In addition, a method of comparison of different research studies discussing various aspects and factors of the correlation of physical activities and AD is used. RESULTS: The findings of this review confirm that in most cases physical activities have a positive effect on the improvement of cognitive decline in AD. CONCLUSION: Although physical activities seem to be beneficial for people with AD, more convincing results, particularly in the area of specific types of exercises and their impact on slowing down the cognitive decline, respectively AD, are needed. PMID- 30277152 TI - Effect of the Interaction Between Hypertension and Cerebral White Matter Changes on the Progression of Alzheimer Disease. AB - BACKGROUND: Cerebrovascular pathologies and hypertension could play a vital role in Alzheimer disease (AD) progression. However, whether cerebrovascular pathologies and hypertension accelerate the AD progression through an independent or interaction effect is unknown. OBJECTIVE: To investigate the effect of the interactions of cerebrovascular pathologies and hypertension on AD progression. METHOD: A retrospective longitudinal study was conducted to compare AD courses in patients with different severities of cerebral White Matter Changes (WMCs) in relation to hypertension. Annual comprehensive psychometrics were performed. WMCs were rated using a rating scale for Age-related WMCs (ARWMC). RESULTS: In total, 278 patients with sporadic AD were enrolled in this study. The mean age of the patients was 76.6 +/- 7.4 years, and 166 patients had hypertension. Among AD patients with hypertension, those with deterioration in clinical dementia rating sum of box (CDR-SB) and CDR had significantly severe baseline ARWMC scales in total (CDR-SB: 5.8 vs. 3.6, adjusted P = 0.04; CDR: 6.4 vs. 4.4, adjusted P = 0.04) and frontal area (CDR-SB: 2.4 vs. 1.2, adjusted P = 0.01; CDR: 2.4 vs. 1.7, adjusted P < 0.01) compared with those with no deterioration in psychometrics after adjustment for confounders. By contrast, among AD patients without hypertension, no significant differences in ARWMC scales were observed between patients with and without deterioration. CONCLUSION: The effect of cerebrovascular pathologies on AD progression between those with and without hypertension might differ. An interaction but not independent effect of hypertension and WMCs on the progression of AD is possible. PMID- 30277153 TI - Conventional versus natural alternative treatments for leishmaniasis :a review. AB - Leishmaniasis is a neglected disease caused by protozoan belonging to the Leishmania genus. There are at least 16 pathogenic species for humans that are able to cause different clinical forms, such as cutaneous or visceral leishmaniasis. In spite of the different species and clinical forms, the treatment is performed with few drug options that, in most cases, are considered outdated. In addition, patients under classical treatment show serious side effects during drug administration, moreover parasites are able to become resistant to medicines. Thus, it is believed and well accepted that is urgent and necessary to develop new therapeutic options to overpass these concerns about conventional therapy of leishmaniasis. The present review will focus on the efficacy, side effects and action mechanism of classic drugs used in the treatment of leishmaniasis, as well as the importance of traditional knowledge for directing a rational search toward the discovery and characterization of new and effective molecules (in vivo assays) from plants to be used against leishmaniasis. PMID- 30277154 TI - Design, Synthesis and Antileishmanial Activity of Naphthotriazolyl-4- Oxoquinolines. AB - BACKGROUND: Leishmaniasis is a neglected public health problem caused by several protozoanspecies of the genus Leishmania. The therapeutic arsenal for treating leishmaniasis is quite limited, raising concerns about the occurrence of resistant strains. Furthermore, most of these drugs were developed more than 70 years ago and suffer from poor efficacy and safety and are not well adapted to the needs of patients. Therefore, research on novel natural or synthetic compounds with antiparasitic activity is urgently needed. In this paper, we evaluated the effect and the mechanism of action of naphthotriazolyl-4 oxoquinolines on promastigotes and intracellular amastigotes of Leishmania amazonensis. MATERIALS AND METHODS: The naphthotriazolyl-4-oxoquinoline derivatives were obtained in good to moderate yields via the [3+2] cycloaddition reaction between 1,4-naphtoquinone and azido-4- oxoquinoline derivatives. HMPA at 100 degrees C was established as the best solvent and temperature condition for this reaction. The structures of the compounds were confirmed by spectral analyses (infrared spectroscopy, one- and two-dimensional 1H and 13C NMR spectroscopy, and high-resolution mass spectrometry). The compounds exhibited promising activities with IC50 values ranging from 0.7 to 2.0 uM against intracellular amastigotes of Leishmania amazonensis. The most selective compound was the Npentyl- substituted derivative, which showed a Selectivity Index (SI) of 8.6, making it less toxic than pentamidine (SI 4.5). RESULTS: Our results demonstrated that all compounds, except the N-propyl-substituted derivative, induce ROS production by parasites early in the culture. As a proof of concept, we demonstrated that the most selective compound was able to interfere with sterol biosynthesis in L. amazonensis. CONCLUSION: The naphthotriazolyl-4 oxoquinoline derivatives were obtained in good to moderate yields. These conjugates have potent in vitro antileishmanial activity involving at least two different mechanisms of action, making them promising lead compounds for the development of new therapeutic alternatives for leishmaniasis. PMID- 30277155 TI - Giardiasis: characteristics, pathogenesis and new insights about treatment. AB - Giardia intestinalis infection causes enterocytes damage and loss of brush border of the epithelial cells of the intestine that leads in shortening of microvilli and altered epithelial barrier function. This pathology curses with aqueous diarrhoea, steatorrhea, nausea, abdominal pain, vomiting and weight loss. However, most infections are either asymptomatic. The main consequence of Giardia colonization is nutrients malabsorption. Several families of drugs with good efficacy are used for Giardia treatment, but sometime dosing regimens are suboptimal and emerging resistance begins to question their clinical value. Moreover, some of these drugs can cause side effects that result in patient discomfort and low adherence to the treatment. This paper reviews the drugs currently used for the treatment against Giardia: the mechanism of action, the efficacy, the normal dosing, side effects and in vitro and clinical studies. In addition, new therapies against Giardia such as those based on phytochemicals, Lactobacillus and nanotechnology are collected in this paper, trying to find the ideal treatment for this disease with maximum efficacy and minimum adverse effects. PMID- 30277156 TI - Natural products for vulvovaginal candidiasis treatment: evidence from clinical trials. AB - BACKGROUND: Candida albicans is an opportunistic yeast that causes more than 90% of all vulvovaginal infections. Because of inherently resistant to antifungals drugs such as azole derivatives, the search for anti-Candida albicans agents with new pharmacological targets is considered as the main therapeutic strategy to prevent and treat these type of infections. In this context, products of natural origin are a promising source of compounds with antifungal activity. OBJECTIVE: The current review analyzes clinical evidence on the effectiveness of natural products in the vulvovaginal Candida albicans infections. METHOD: A literature review in the electronic databases PubMed, Google Scholar, Cochrane Library Plus, Web of Science, Latin American and Caribbean Literature on Health Sciences (Lilacs) and Scientific Electronic Library Online (SciELO) using the search terms "natural products", "phytotherapy", "vulvovaginal candidiasis" and "clinical trials" together with the Boolean term 'AND' was performed. English, Spanish and French articles without restriction of date of publication were considered. RESULTS: A total of 13 clinical trials (most of them randomized clinical trials which used azoles as control group) that evaluate the anti-Candida activity of a total of 11 different natural products (i.e. Zataria multiflora essential oils, Ageratina pichinchensis and Solanum nigrescens extracts and saponins from Solanum chrysotrichum, among others) against vulvovaginitis have been included in the current review. CONCLUSION: Because of the few clinical trials it is difficult to establish a consistent conclusion about the effectiveness of natural products in the prevention and treatment of vulvovaginitis caused by Candida albicans. Future studies should be aimed at evaluating new natural products as well as conducting more clinical research with promising natural substances already investigated in clinical trials. PMID- 30277157 TI - Paracoccidioides spp. and Histoplasma capsulatum: current and new perspectives for diagnosis and treatment. AB - The thermally-dimorphic systemic fungal group includes several important human pathogens: Blastomyces dermatitidis, Coccidioides immitis and C. posadasii, Histoplasma capsulatum, Paracoccidioides brasiliensis, P. lutzii, and Talaromyces (Penicillium) marneffei. They usually are geographically restricted and have natural habitats in soil or in plants, and when fungal propagules invade mammalian host by inhalation, they initiate an inflammatory reaction that can result in self-resolution of the infection or cause an acute or chronic disease. In the setting of the AIDS pandemic and the developments in modern medicine, such as immunosuppressive therapy in cancer surgery patients and in transplantation and autoimmune diseases, the incidence of endemic mycoses has progressively increased. Another important factor of the increased incidence of systemic mycoses in certain regions is the progressive devastation of tropical and subtropical forests. In this review, we focus on two of the most important systemic mycoses: paracoccidioidomycosis and histoplasmosis, and their major characteristics in epidemiology, clinical aspects and laboratorial diagnosis. PMID- 30277158 TI - Treatment of toxoplasmosis and neosporosis in farm ruminants: state of knowledge and future trends. AB - Toxoplasmosis and neosporosis are closely related protozoan diseases that lead to important economic impacts in farm ruminants. Toxoplasma gondii infection mainly causes reproductive failure in small ruminants and is a widespread zoonosis, whereas Neospora caninum infection is one of the most important causes of abortion in cattle worldwide. Vaccination has been considered the most economic measure for controlling these diseases. However, despite vaccine development efforts, only a live-attenuated T. gondii vaccine has been licensed for veterinary use, and no promising vaccines against neosporosis have been developed; therefore, vaccine development remains a key goal. Additionally, drug therapy could be a valuable strategy for disease control in farm ruminants, as several drugs that limit T. gondii and N. caninum proliferation and dissemination have been evaluated. This approach may also be relevant to performing an initial drug screening for potential human therapy for zoonotic parasites. Treatments can be applied against infections in adult ruminants to minimize the outcomes of a primo-infection or the reactivation of a chronic infection during gestation or in newborn ruminants to avoid infection chronification. In this review, the current status of drug development against toxoplasmosis and neosporosis in farm ruminants is presented, and in an effort to promote additional treatment options, prospective drugs that have shown efficacy in vitro and in laboratory animal models of toxoplasmosis and neosporosis are examined. PMID- 30277159 TI - Extracellular vesicles and insulin resistance: a potential interaction in vascular dysfunction. AB - Insulin resistance plays a key role in cardiovascular complications associated with diabetes mellitus and hypertensive disorders. In states of insulin resistance several circulating factors may contribute to a defective insulin sensitivity in different tissues, including the vasculature. One of these factors influencing the vascular insulin resistance are the extracellular vesicles. The extracellular vesicles include exosomes, microvesicles, and apoptotic bodies which are released to the circulation by different vascular cells. Since the cargo of extracellular vesicles seems to be altered in metabolic complications associated with insulin resistance, these vesicles may be candidates contributing to vascular insulin resistance. Despite of the studies linking insulin resistance signalling pathways with the vascular effect of extracellular vesicles, the involvement of these structures in vascular insulin resistance is a phenomenon that remains unclear. PMID- 30277160 TI - Herbal Drug Use In Sickle Cell Disease Management; Trends And Perspectives In Sub Saharan Africa. AB - Introduction Nigeria has the largest burden of Sickle Cell Disease (SCD) with estimated 100,000 new born affected annually. SCD is a hemoglobin (Hb) disorder with the major form resulting from the substitution of a polar glutamate (Glu) by non-polar Valine (Val) in an invariant region, of Hb? chain-subunit. Species of Hb found in sickle cell trait are HbA and HbS at a 60:40 proportion, in SCD only HbS, in the HbC disease only HbC, and in the SC disease it's HbS and HbC in a 50:50 equal proportion. Objective This paper reviews herbal medicines usagein sub Saharan Africa (sSA) to ameliorate the crisis associated with SCD.The model Hb tetramer, suggest a higher membrane affinity of HbS and HbC, promoting dehydration of RBCs, with concomitant in vivo crystallization. Some drawback using these herbal drugs includes; poorbioavailability and the lack of proper pharmacovigilance monitoring procedures arising from weak governance structure combined with under reporting of herbal usage tophysicians was also discussed. Probable epigenetic loci that could be targeted using phytomedicines for effective SCD management are discussed. Methods Using search engines, several databases including Google scholar, PubMed, Academic Resource Index were utilized to source for relevant publications/literatures. The protein coordinates for the Hb tetramer were obtained from the Protein Data Bank (PDB). Conclusion Manipulation of epigenetics to achieve better SCDmanagement involvescareful thinking.Herein, we discuss some epigenetic interactionsthat could be putatively tweaked with a view to enhancing solublebioactive small molecular components with potential to reactivate gamma -globin genes, boosting immune response in-patient with SCD. PMID- 30277161 TI - The impact of depressive symptoms on quality of life of patients with type 2 diabetes in Jazan region, KSA. AB - PURPOSE: The purpose of this study is to determine the impact of depressive symptoms on the quality of life of type 2 diabetes patients (T2DM). METHOD: A cross sectional study of 332 T2DM patients aged >=18 years living in Jazan region of Saudi Arabia. Validated questionnaire was used for demographic and disease characteristics. Depressive symptoms of the participants were assessed using the Patient Health Questionnaire (PHQ-9). The Quality of Life Enjoyment and Satisfaction Questionnaire - Short Form (Q-LES-Q-SF) was utilized to assess the degree of life enjoyment and satisfaction. RESULTS: Depressive symptoms were met in 34.7% (112) of the total participants. The overall sense of wellbeing (mean 3.23, P .value 0.000), physical (mean 3.37, P .value 0.003), psychosocial (mean 2.99 P .value 0.000) and social domains (mean 3.53, P .value 0.000) of quality of life were significantly reduced in T2DM patients with depressive symptoms. CONCLUSION: The impact of depressive symptoms on quality of life of T2DM patients was more significant than the impact of diabetes alone. Symptoms of depression reduce the individual coping and hence reduce functioning. This study emphases the vital importance of an integrated holistic approach that addresses both the practical and emotional issues in diabetes care. PMID- 30277162 TI - Myxedema Heart Disease: A rare disease entity. Case report and brief review of the literature. AB - BACKGROUND: Myxedema heart disease is an extremely rare disease entity and should be suspected in patients with unexplained heart failure refractory to conventional treatment. Myxedema coma with co- existent heart disease is not well known and very few cases have been reported. CONCLUSION: Here we present an interesting case of myxedema coma with severe valvular cardiomyopathy followed by a concise review of the literature with special emphasis on epidemiology, pathophysiology, diagnosis and therapeutic modalities. PMID- 30277163 TI - Anaemogenic, Obesogenic And Thermogenic Potentials Of Graded Doses Of Monosodium Glutamate Sub-Acutely Fed To Experimental Wistar Rats. AB - BACKGROUND: Monosodium glutamate (MSG) is one of the most commonly used food additives for the enhancement of food taste and flavour. There are several conflicting reports of toxicity or otherwise safety of the compound, which raises a growing concern regarding the safety of monosodium glutamate as food additive. OBJECTIVE: In the present study, we sought to investigate the effect of monosodium glutamate on body weight, feed consumption, body temperature and some haematological parameters. METHODOLOGY: Twenty adult Wistar rats divided into four groups of five rats each were used for the study. Rats in groups 1, 2 and 3 were given feed thoroughly mixed with 3, 6 and 9 g of monosodium glutamate respectively for 14 days, while rats in group 4 (Control) were given only the feed for the same period of time. Body weight, temperature, feed consumption, and some haematological parameters were measured before the addition of the compound to the feed and thereafter for every 2 days for a period of 14 days. RESULTS: Our findings indicated significant changes (P < 0.05) in the red blood cells (RBC) count, packed cell volume (PCV), as well as body temperature in all the treated groups compared to the control group. The result also revealed a significant dose dependent increase in body weight in the groups treated with 6 and 9 g of monosodium glutamate compared to the control, the body weight correlated positively with the duration of monosodium glutamate consumption. CONCLUSION: The current data suggest that consumption of high doses/quantity of monosodium glutamate for a long duration of time could lead to anaemia due to decrease in red blood cell count and packed cell volume and obesity resulting from increase in body. PMID- 30277164 TI - Safety of Vinflunine in patients with advanced urothelial carcinoma refractory to platinum-based chemotherapy: a prospective pilot study. AB - BACKGROUND: Several single chemotherapeutic agents have been evaluated as second line treatment of advanced urothelial carcinoma. Despite encouraging efficacy outcomes, toxicity has often led to dose modifications or discontinuation. We aimed to assess safety of vinflunine in a particular population of advanced transitional cell carcinoma of urothelium (TCCU), that were exposed to previous toxicity of chemotherapy. METHODS: This is an open-label, prospective, single center pilot study to evaluate the response rate and safety profile of vinflunine in patients with advanced TCCU. It was planned to enroll 25 evaluable patients. Eligible patients are those with progressive disease after first line platinum based regimen for advanced or metastatic disease. RESULTS: The study was prematurely closed due to two sudden deaths that were judged by the review board as treatment-related. Only ten patients were evaluated and received at least one cycle of vinflunine. All but one were male and seven underwent radical surgery. Eight had a distant metastasis (mainly lung and/or liver). Disease control rate was 40%, four patients had a partial response with median duration of response of 3.5 months. The median overall survival was 3.2 months (95% CI:1.67- 4.73). There were three serious adverse events namely two sudden deaths and one grade 4 thrombocytopenia. Nine grade 3/4 adverse events occurred. The most common all grade adverse events were fatigue (50%), constipation (40%) and vomiting (40%). Moreover, grade 3 fatigue occurred in 30% of patients. Only one patient, who achieved PR for 5 months, was fit to receive further cytotoxic chemotherapy. CONCLUSION: The activity of vinflunine in advanced urothelial carcinoma came at the expense of its safety. The use of vinflunine has to be limited to selected group of patients. However, this is a single institute experience in a limited number of patients. PMID- 30277165 TI - Biochemical and Pharmacological Applications of Essential Oils in Human Health Especially in Cancer Prevention. AB - : Background - At present, 'pharmaco-epigenomics' constitutes the hope in cancer treatment owing to epigenetic deregulation- a reversible process and playing a role in malignancy. OBJECTIVE: Chemotherapy has many limitations like host-tissue toxicity, drug resistance. Hence, it is imperative to unearth targets to better treat cancer. Here, we intend to repurpose a set of our previously synthesized difluorinated propanediones (PR) as histone lysine methyltransferase inhibitors (HMTi). METHODS: The cell lines of leukemic origin viz. histiocytic lymphoma (U937) and acute T-cell leukemia (JURKAT) were treated with PR-1 to 7 after docking studies with active pocket of HMT. The cell cycle analysis, in vitro methylation and cell proliferation assays were carried out to delineate their physiological role. Results - A small molecule PR-4, at 1 and 10MUM, has shown to alter the methylation of histone H3 and H4 in both cell lines. Also, treatment shows an increase in G2/M population and a subsequent decrease in the G0/G1 population in U937. In JURKAT, an increase in both G2/M and S phase population was observed. The sub-G1 population showed a steady rise with increase in dose and prolonged time intervals in U937 and JURKAT cell lines. In SRB assay, the PR showed a cell growth of 42.6 and 53.4% comparable to adriamycin; 44.5 and 53.2% in U937 and JURKAT, respectively. The study suggests that PR-4 could emerge as a potential HMT inhibitor. Conclusion - The molecule PR-4 could be a lead in developing more histone lysine methyltransferases inhibitors with potential to be pro-apoptotic agents. PMID- 30277166 TI - Spectroscopic and in silico DNA binding studies on the interaction of some new N substituted rhodanines with calf-thymus DNA: In vitro anticancer activities. AB - BACKGROUND: Cancer is a black spot on the face of humanity in this era of science and technology. Thus, the search for new promising anticancer agents continues. AIMS: Here we designed and synthesized new N-substituted rhodanines (RD1-7), evaluated their multi-spectroscopic interaction with calf thymus DNA, in silico and anticancer studies against human breast cancer cell (MDA-MB-231). METHODS: Among the compounds, RD5 was found the most potent by MTT assay with IC50 value of 17.24MUg/ml. In addition, DNA binding study carried out by UV-Vis and fluorescence techniques revealed strong binding affinity of RD1-7 with DNA (Kb in the range of 1.5 - 7.4 * 105 M-1). Moreover, theoretical in silico DNA binding study supported the experimental DNA binding and anticancer studies. RESULTS: It was observed that DNA-compound adducts were stabilized by H-bonding and hydrophobic attractions. The compounds preferred to enter into minor grooves of DNA. Concisely, the compounds showed encouraging therapeutic properties and, therefore, have a promising future and compounds RD1, RD2, and RD5 are promising scaffolds for the development of novel anticancer drugs. PMID- 30277167 TI - A Brief History of Ebolavirus disease: Paving the Way Forward by Learning from the Previous Outbreaks. AB - In this review, Ebolavirus disease (EVD) outbreaks have been comprehensively reviewed from their beginning until now. It chronologically discusses how each outbreak was tackled, national and international actions taken, diagnostic methods applied, the infection control procedures were put in place, and the lessons learnt from each epidemic for the control of subsequent epidemics. Data for this review were obtained from literature published between 1967 and 2016 in key medical databases, the official websites of various governmental organisations, international public health agencies, and regulatory bodies. Despite major developments in the field of EVD, there has been little progress in its specific therapy or prevention. Historically, individuals who recovered from EVD acted as a source of fresh frozen plasma (containing IgG) that has been used to treat other acutely ill patients, however this therapeutic modality has limitations due to the risk of transmission of blood-borne infections. With the use of advanced and efficient purification methods the incidence of unwanted side effects following immune serum therapy has currently been greatly reduced. Creation of a safe plasma pool that covers immunoglobulins against all strains of EVD is now a research priority.

AB - BACKGROUND: Chemotherapy as a science began within the 1st decade of the twentieth century with understanding of the principles of selective toxicity, the particular chemical relationships between microorganism pathogens and medicines, the event of drug resistance, and also the role of combined medical aid. OBJECTIVES: This review aims to highlight the characteristics, specifically the pharmacokinetic parameters, and the analytical methods reported in literature for the determination of Cefquinome, a fourth generation cephalosporineused to treat Gram-positive and Gram-negative caused infections. CONCLUSION: Analysis of such drugs, whether used for treatment of human or animal illness, is essential in understanding the bioavailability and therapeutic control which will ensure their activity and safety. PMID- 30277169 TI - Hand hygiene compliance and effectiveness against respiratory infections among Hajj pilgrims: a systematic review. AB - The role of hand hygiene in the prevention of respiratory tract infections in Hajj pilgrims has not been assessed through a focussed systematic review of the literature. To this end, a systematic review was undertaken to synthesize the up to-date literature on the compliance and effectiveness of hand hygiene among Hajj attendees. Major databases, including OVID Medline, were searched by using a combination of MeSH terms and text words for potentially relevant articles. Data from identified articles were abstracted, quality assessed and combined into a summary effect. Twelve observational studies containing data of 6,320 pilgrims were included. The compliance of hand washing with non-alcoholic surfactants was 77.7% (ranged from 31.5% to 90.3% in individual studies) and the compliance of hand cleaning with alcoholic products was 44.9% (ranged from 30.7% to 67.4%). Education was a key influencer of hand hygiene practice. Only three of six studies that assessed the effectiveness of hand hygiene against clinical disease found the practice to be effective, and only one of two studies that evaluated its effectiveness against a laboratory-confirmed infection found it to be effective. This systematic review suggests that hand hygiene using non-alcoholic products is generally acceptable among Hajj pilgrims but there is no conclusive evidence on its effectiveness. PMID- 30277170 TI - Hepatitis B Seroepidemiology in Australia One Decade after Universal Vaccination of Infants and Adolescents. AB - This study assessed the impact of the staged introduction of universal infant and adolescent catch-up hepatitis B vaccination programs on the prevalence of immunity and past hepatitis B virus (HBV) infection in targeted cohorts over almost a decade in Australia. We compared the prevalence of immunity in relevant cohorts of children and adolescents in repeated national serological surveys conducted in 1998-99, 2002 and 2007. Residual sera (n =2210) collected opportunistically from Australian laboratories in 2007 were tested for antibody to hepatitis B surface antigen (anti-HBs) indicating vaccine-induced immunity; sera from persons aged 12-29 years with anti-HBs detected (n =386) were then tested for hepatitis B core antibody (anti-HBc) to identify past hepatitis B infection. In 2007, compared with the baseline period of 1998-99, anti-HBs prevalence had increased significantly in all age groups below 24 years, more than doubling in target children. Prevalence of anti-HBc was zero in the 12-14 years and reduces by 71% in those aged 15-19 years. The hepatitis B vaccination protected a significant number of targeted adolescents with a modest vaccine uptake (57% to 60% nationally). In a setting without incentives or school entry requirements, adolescent vaccination coverage was significantly higher when delivered by school-based rather than GP-based mechanisms. A cohort of children was growing up in Australia with high prevalence of vaccine-induced immunity against hepatitis B, providing the best opportunity for controlling HBV infection in Australia. PMID- 30277171 TI - Immunization status of mothers of children with cerebral palsy in rural Bangladesh. AB - BACKGROUND: Vaccination is one of the most effective public health tools for prevention of infectious diseases, morbidity and disability. Little is known about the rate of maternal immunization among mothers of children with cerebral palsy (CP), as well as any possible role of maternal immunization in development of CP in the newborns. OBJECTIVE: To determine the socio-demographic characteristics and self-reported vaccination status of mothers of children with CP and compare vaccination coverage in this cohort with national data on immunization. The study also aims to assess vaccination status of children with CP. METHOD: A subset of the Bangladesh CP Register (BCPR) cohort of women who had children with CP were recruited during April 2017 from a community based early intervention and rehabilitation program going on in Shahjadpur . Socio demographic characteristics and maternal immunization status were assessed using a semi-structured questionnaire . The vaccination status of the children was also assessed by interviewing mother and observing the BCG marks. All data were compared with the corresponding information among general population using national vaccination coverage survey reports of the Ministry of Health and Family Welfare, Bangladesh. RESULT: Sixty-eight mothers were interviewed of which 17.6% mothers reported not receiving any vaccine during pregnancy. Tetanus vaccine was most commonly (82.0%) received during pregnancy. Overall coverage for at least two doses of tetanus toxoid (TT) among mothers of children with CP was significantly lower than the national tetanus coverage (79.4% versus 96.4%, p<0.01). Forty two (61.7%) mothers with a child with CP reported to have not received tetanus vaccine during their pregnancy compared to only twenty (29.4%) mothers with healthy children reported missing tetanus vaccination during their pregnancy. This difference was statistically significant (p<0.01). Hepatitis B and influenza vaccine were received by mothers of children with CP during antenatal period (2 and 6 respectively). CONCLUSION: Immunization among mothers of children with CP is significantly poorer than the national coverage. Also, the immunization of the children with CP is poorer than the national EPI coverage. Our findings reflect that necessity for specific strategies to improve the vaccination coverage among mothers of children with disabilities especially CP and the children with CP. PMID- 30277172 TI - Murine skin-resident gammadeltaT cells impair the immune response to HSV in skin. AB - HSV is an important cause of brain infection. Virus entry is often through breeches in the skin. gammadeltaT cells play an immunoprotective role in mice after corneal, genital or footpad (subcutaneous) HSV infection. Here we report that the presence of gammadeltaT cells in murine skin is associated with increased severity of herpetic disease, reduced protective cytokine responses and increased viral spread from the skin to the sensory ganglia in the zosteriform model. gammadeltaT cell-deficient (TCR delta -/-) mice displayed significantly decreased herpetic lesion severity after flank HSV infection compared to WT C57BL/6 controls at both primary and secondary skin infection sites. Viral titer at the primary skin site was similar to WT mice in gammadeltaT cell-deficient mice, but was significantly decreased in the ganglia and secondary skin site. gammadeltaT cell-deficient mice showed increased Th1 responses by both T cells and non-T cells at the primary site, and decreased T-cell Th17 responses and immune infiltration at the secondary site. Cytokine responses of epidermal and dermal gammadeltaT cells to HSV also differed in WT mice (Th1 in epidermis, and Th17 in the dermis), suggesting a functional dichotomy between these two subsets. Our data suggest that in contrast to other mouse models of HSV infection, skin resident gammadeltaT cells impair the immune response to HSV in skin. PMID- 30277173 TI - Novel Compound from Flowers of Moringa oleifera Competently Active against Multi Drug Resistant Gram-negative Bacilli. AB - BACKGROUND: The need for suitable antibacterial agents effective against Multi drug resistant Gram-negative bacteria is acknowledged globally. The present study was designed to evaluate possible antibacterial potential of an extracted compound from edible flowers of Moringa oleifera. METHODS: Five different solvents were used for preparing dried flower extracts. The most effective extract was subjected to fractionation and further isolation of the active compound with highest antibacterial effect was obtained using TLC, Column Chromatography and reverse phase- HPLC. Approaches were made for characterization of the isolated compound using FTIR, NMR and Mass spectrometry. Antibacterial activity was evaluated according to the CLSI guidelines. RESULTS: One fraction of aqueous acetic acid extract of M. oleifera flower was found highly effective and more potent than conventional antibiotics of different classes against Multi-drug resistant Gram-negative bacilli (MDR-GNB) when compared. The phyto-chemical analysis of the isolated compound revealed the presence of hydrogen bonded amine and hydroxyl groups attributable to unsaturated amides. CONCLUSIONS: The present study provided data indicating a potential for use of the flowers extract of M. oleifera in the fight against infections caused by lethal MDR-GNB. RECOMMENDATIONS: Aqueous acetic acid flower extract of M. oleifera is effective, in-vitro, against Gram-negative bacilli. This finding may open a scope in pharmaceutics for the development of new classes of antibiotics. PMID- 30277174 TI - Animal models optimise nanoparticles for drug delivery in the treatment of hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) causes significant morbidity and high fatal outcome globally. Conventional therapeutic strategies have achieved significant improvements for HCC, but they have limitations and are far from ideal. Novel nanoparticulate drug delivery systems have recently presented great therapeutic potential for HCC. The potential for successful clinical translation of formulation strategies can only be evaluated by using appropriate and accurate pre-clinical models. This review will provide an overview of different animal models of HCC, with a particular emphasis on those applied to assess the translational potential for drug nanopharmaceutics. PMID- 30277175 TI - Review: Precision nutrition of ruminants: approaches, challenges and potential gains. AB - A plethora of sensors and information technologies with applications to the precision nutrition of herbivores have been developed and continue to be developed. The nutritional processes start outside of the animal body with the available feed (quantity and quality) and continue inside it once the feed is consumed, degraded in the gastrointestinal tract and metabolised by organs and tissues. Finally, some nutrients are wasted via urination, defecation and gaseous emissions through breathing and belching whereas remaining nutrients ensure maintenance and production. Nowadays, several processes can be monitored in real time using new technologies, but although these provide valuable data 'as is', further gains could be obtained using this information as inputs to nutrition simulation models to predict unmeasurable variables in real-time and to forecast outcomes of interest. Data provided by sensors can create synergies with simulation models and this approach has the potential to expand current applications. In addition, data provided by sensors could be used with advanced analytical techniques such as data fusion, optimisation techniques and machine learning to improve their value for applications in precision animal nutrition. The present paper reviews technologies that can monitor different nutritional processes relevant to animal production, profitability, environmental management and welfare. We discussed the model-data fusion approach in which data provided by sensor technologies can be used as input of nutrition simulation models in near-real time to produce more accurate, certain and timely predictions. We also discuss some examples that have taken this model-data fusion approach to complement the capabilities of both models and sensor data, and provided examples such as predicting feed intake and methane emissions. Challenges with automatising the nutritional management of individual animals include monitoring and predicting of the flow of nutrients including nutrient intake, quantity and composition of body growth and milk production, gestation, maintenance and physical activities at the individual animal level. We concluded that the livestock industries are already seeing benefits from the development of sensor and information technologies, and this benefit is expected to grow exponentially soon with the integration of nutrition simulation models and techniques for big data analysis. However, this approach may need re-evaluating or performing new empirical research in both fields of animal nutrition and simulation modelling to accommodate a new type of data provided by the sensor technologies. PMID- 30277176 TI - Retrospective evaluation of a clinical decision support tool for effective computed tomography angiography utilization in urgent brain imaging of suspected TIA/minor stroke in the emergency department. AB - CLINICIAN'S CAPSULE What is known about the topic? Canadian guidelines recommend that suspected transient ischemic attack (TIA) patients receive brain imaging in the emergency department; yet, high requisition rates for non-cerebrovascular patients exist. What did this study ask? What is the hypothetical impact that a clinical decision support tool (CDST) would have on computed tomography angiography (CTA) requisitions for suspected TIA patients. What did this study find? CDST use would have resulted in more TIA patients receiving CTA, while imaging fewer non-cerebrovascular patients. Why does this study matter to clinicians? A CDST could assist clinicians in applying the Canadian stroke guidelines as pragmatically as possible. PMID- 30277177 TI - Evaluation of emergency department ultrasound machines for the presence of occult blood. AB - CLINICIAN'S CAPSULE What is known about the topic? Bedside ultrasound is a frequently used tool in the emergency department (ED), with no standard cleaning protocols in place. What did this study ask? Is there visible and occult contamination of the ED ultrasound machine after daily use and in trauma? What did this study find? This study found that the ultrasound machine tested positive for occult blood contamination on 10% of daily tests and on 43% of assessments after use in trauma. Why does this study matter to clinicians? Standard cleaning practices should be implemented to reduce contamination rates.

AB - OBJECTIVE: The intent of this study was to determine whether there are differences in disaster preparedness between urban and rural community hospitals across New York State. METHODS: Descriptive and analytical cross-sectional survey study of 207 community hospitals; thirty-five questions evaluated 6 disaster preparedness elements: disaster plan development, on-site surge capacity, available materials and resources, disaster education and training, disaster preparedness funding levels, and perception of disaster preparedness. RESULTS: Completed surveys were received from 48 urban hospitals and 32 rural hospitals.There were differences in disaster preparedness between urban and rural hospitals with respect to disaster plan development, on-site surge capacity, available materials and resources, disaster education and training, and perception of disaster preparedness. No difference was identified between these hospitals with respect to disaster preparedness funding levels. CONCLUSIONS: The results of this study provide an assessment of the current state of disaster preparedness in urban and rural community hospitals in New York. Differences in preparedness between the two settings may reflect differing priorities with respect to perceived threats, as well as opportunities for improvement that may require additional advocacy and legislation.

AB - SummaryPrevious studies have established a model of atresia in preovulatory follicles after stimulation of immature rats with equine chorionic gonadotropin (eCG). This gonadotropin recruits a follicular pool and the deprivation of preovulatory luteinizing hormone (LH) surge induces the atresia in preovulatory follicles. The present study investigated the occurrence of ovulation and provided some morphological features of granulosa cell (GC) apoptosis of atretic follicles at 0, 48, 72 and 120 h after eCG stimulation. Histological sections of ovaries from untreated animals (0 h) showed primordial, primary, secondary and early antral follicles. After 48 h ovaries showed large antral follicles. Preovulatory follicles were observed at 72 h, and two out of five rats displayed cumulus-oocyte complexes (COCs) in the oviducts. All animals exhibited corpora lutea after 120 h. We observed increased estradiol (E2) levels 48 h after eCG treatment that might trigger an endogenous preovulatory gonadotropin surge. Higher progesterone (P4) level, which is the hallmark of a functional corpus luteum, was observed at 120 h. Atresia in secondary and antral follicles was observed by pyknotic granulosa cell nuclei in histology and positive immunolabelling for cleaved caspase 3. We also observed macrophages in secondary and antral follicles in atresia. Transmission electron microscopy revealed GCs with compacted chromatin against the nuclear envelope, nuclear fragmentation, cell shrinkage and fragmentation. No preovulatory follicles showed apoptosis of GCs. In conclusion, our results suggested the occurrence of an endogenous gonadotropin surge, promoting ovulation and preventing atresia of preovulatory follicles. PMID- 30277181 TI - Disparity Surface Reconstruction Based on a Stereo Light Microscope and Laser Fringes. AB - Microscopic vision systems based on a stereo light microscope (SLM) are used in microscopic measuring fields. Conventional measuring methods output the disparity surface based on stereo matching methods; however, these methods require that stereo images contain sufficient distinguishing features. Moreover, matching results typically contain many mismatched points. This paper presents a novel method for disparity surface reconstruction by combining an SLM and laser measuring techniques. The surfaces of small objects are scanned by a laser fringe, and a stereo image sequence containing laser stripes is obtained. The central contours of the laser stripes are extracted, and central contours are derived for alignment. A disparity coordinate system is then defined and used to analyze the relationship between the motion direction and reference plane. Next, the method of aligning disparity contours is proposed. The results show that our method can achieve a precision of +/-0.5 pixels and that the real and measured shapes described by the disparity surface are consistent based on our method. Our method is confirmed to perform much better than the conventional block-matching method. The disparity surface output obtained by our method can be used to measure the surface profiles of microscopic objects accurately. PMID- 30277182 TI - Impact of the Aliso Canyon Gas Leak on Respiratory-Related Conditions Among US Department of Veterans Affairs (VA) Users. AB - BACKGROUND: The largest gas leak in United States history occurred October 2015 through February 2016 near Porter Ranch (PR), California, and prompted the temporary relocation of nearby residents because of health concerns related to natural gas exposure. METHODS: A retrospective cohort study was conducted using US Department of Veterans Affairs (VA) administrative and clinical data. On the basis of zip codes, we created two groups: PR (1920 patients) and San Fernando Valley (SFV) (15 260 patients) and examined the proportion of outpatient visits to VA providers with respiratory-related diagnoses between October 2014 and September 2017. RESULTS: We observed an increase in the proportion of visits in the PR group during the leak (7.0% vs 6.1%, P<0.005) and immediately after the leak (7.7% vs 5.3%, P<0.0001). For both groups, we observed a decrease in respiratory diagnoses one year after the leak (7.0% to 5.9%, P<0.05 PR; 6.1% to 5.7%, P<0.01 SFV). CONCLUSION: Exposure to natural gas likely led to the observed increase in respiratory-related diagnoses during and after the PR gas leak. Early relocation following natural gas leaks may mitigate respiratory exacerbations. (Disaster Med Public Health Preparedness. 2018;page 1 of 5). PMID- 30277183 TI - Reassessment (after 15 Years) of Non-Patient Adults by the Rorschach Method. AB - The investigation of personality using the Rorschach Method has been historically established, however, its proper use requires continuous study, especially in regard to reliability, validity and normative references. This study's objective was to verify stability indicators of Rorschach (French Approach) through a reassessment (after 15 years) of non-patient adults previously addressed in the normative study by Pasian (1998). A total of 88 adults, aged between 34 and 69 years old, of both sexes, with different socio-economic and educational levels, were reassessed in 2013 in the state of Sao Paulo, Brazil. The responses were independently rated by different judges, with adequate precision. The average results obtained collected in 1998 and 2013 were analyzed to determine if these two sets of data were significantly different from each other (Student's t test, p <= .05) and the following variables were compared: Productivity indices, Apprehension Modes/Location, Formal Quality, Determinants, Contents and Banality. The overall stability level in these variables is considerable (mean r = .28, +/- SD = 0.21). We discuss the theoretical approach of the Rorschach method regarding structural aspects of personality and developmental issues in personality assessment. PMID- 30277184 TI - Needs Assessment for a Targeted Health Promotion Campaign. AB - ABSTRACTSince the first human A/H7N9 infection in Hong Kong, there has been an ongoing threat of human-to-human transmission, potentially causing a pandemic. Because there is no vaccine for A/H7N9, the individual preventive measures become all the more important for reducing transmission. However, due to the ongoing threat of numerous avian influenza viruses, the public may suffer from pandemic media-fatigue. This study was done to assess the need for a targeted A/H7N9 health promotion campaign. Steven and Gillam's framework using epidemiological, comparative, and corporate approaches was used to assess the need for a targeted A/H7N9 health promotion campaign.Local surveillance data showed that Hong Kong faces a double burden of increasing seasonal influenza activity and threat of an avian influenza pandemic. Experts warned of potential severity and difficulties in A/H7N9 control. In contrast, surveys showed that the Hong Kong public were suffering from pandemic-media-fatigue, lacked anxiety, had misconceptions, and were not vigilant in preventive practices. This was more evident in certain demographics. Content analysis showed that health promotion materials were not targeted or tailored in countries with human A/H7N9 cases. Targeted health promotion campaigns and framing the issue to increase public and media awareness are crucial in preventing the current pandemic-media-fatigue.

AB - OBJECTIVE: To determine the degree of food environment policies that have been implemented and supported by the Malaysian Government, in comparison to international best practice, and to establish prioritised recommendations for the government based on the identified implementation gaps. DESIGN: The Healthy Food Environment Policy Index (Food-EPI) comprises forty-seven indicators of government policy practice. Local evidence of each indicator was compiled from government institutions and verified by related government stakeholders. The extent of implementation of the policies was rated by experts against international best practices. Rating results were used to identify and propose policy actions which were subsequently prioritised by the experts based on 'importance' and 'achievability' criteria. The policy actions with relatively higher 'achievability' and 'importance' were set as priority recommendations for government action. SETTING: Malaysia. SUBJECTS: Twenty-six local experts. RESULTS: Majority (62 %) of indicators was rated 'low' implementation with no indicator rated as either 'high' or 'very little, if any' in terms of implementation. The top five recommendations were (i) restrict unhealthy food marketing in children's settings and (ii) on broadcast media; (iii) mandatory nutrition labelling for added sugars; (iv) designation of priority research areas related to obesity prevention and diet-related non-communicable diseases; and (v) introduce energy labelling on menu boards for fast-food outlets. CONCLUSIONS: This first policy study conducted in Malaysia identified a number of gaps in implementation of key policies to promote healthy food environments, compared with international best practices. Study findings could strengthen civil society advocacies for government accountability to create a healthier food environment. PMID- 30277186 TI - Cognitive test battery for evaluating elderly Chinese Americans. AB - : ABSTRACTObjectives:This study aimed to determine the diagnostic utility of a Chinese test battery for evaluating cognitive loss in elderly Chinese Americans. METHODS: Data from a pilot study at the Mount Sinai Alzheimer's Disease Research Center was examined. All participants were > 65 years old, primarily Chinese speaking, with adequate sensorimotor capacity to complete cognitive tests. A research diagnosis of normal mild cognitive impairment (MCI) or Alzheimer's disease (AD) was assigned to each participant in consensus conference. Composite scores were created to summarize test performance on overall cognition, memory, attention executive function, and language. Multivariable logistic regression models were used to assess the sensitivity of each cognitive domain for discriminating three diagnostic categories. Adjustment was made for demographic variables (i. e., age, gender, education, primary language, and years living in the USA). RESULTS: The sample included 67 normal, 37 MCI, and 12 AD participants. Performance in overall cognition, memory, and attention executive function was significantly worse in AD than in MCI, and performance in MCI was worse than in normal controls. Language performance followed a similar pattern, but differences did not achieve statistical significance among the three diagnostic groups. CONCLUSIONS: This study highlights the need for cognitive assessment in elderly Chinese immigrants.

AB - : ABSTRACTBackground:This study investigated the characteristics of subjective memory complaints (SMCs) and their association with current and future cognitive functions. METHODS: A cohort of 209 community-dwelling individuals without dementia aged 47-90 years old was recruited for this 3-year study. Participants underwent neuropsychological and clinical assessments annually. Participants were divided into SMCs and non-memory complainers (NMCs) using a single question at baseline and a memory complaints questionnaire following baseline, to evaluate differential patterns of complaints. In addition, comprehensive assessment of memory complaints was undertaken to evaluate whether severity and consistency of complaints differentially predicted cognitive function. RESULTS: SMC and NMC individuals were significantly different on various features of SMCs. Greater overall severity (but not consistency) of complaints was significantly associated with current and future cognitive functioning. CONCLUSIONS: SMC individuals present distinctive features of memory complaints as compared to NMCs. Further, the severity of complaints was a significant predictor of future cognition. However, SMC did not significantly predict change over time in this sample. These findings warrant further research into the specific features of SMCs that may portend subsequent neuropathological and cognitive changes when screening individuals at increased future risk of dementia. PMID- 30277189 TI - Dairy cow nutrition in organic farming systems. Comparison with the conventional system. AB - The energy supplied by the high-forage diets used in organic farming may be insufficient to meet the requirements of dairy cattle. However, few studies have considered this problem. The present study aimed to analyze the composition of the diets and the nutritional status (focusing on the energy-protein balance of the diets) of dairy cattle reared on organic farms in northern Spain, which are similar to other organic farming systems in temperate regions. Exhaustive information about diets was obtained from organic (ORG) and representative conventional grazing (GRZ) and conventional no-grazing (CNG) farms. Samples of feed from the respective farms were analyzed to determine the composition. Overall, the diets used on the ORG farms were very different from those used on the CNG farms, although the difference was not as evident for GRZ. The CNG farms were characterized by a higher total dry matter intake with a high proportion of concentrate feed, maize silage and forage silage. By contrast, on ORG and GRZ farms, the forage, pasture and fibre intake were the most important variables. The ration used on ORG farms contained a significantly higher percentage of ADF and lower organic matter (OM) content than the rations used in both of the conventional farming systems, indicating that the diets in the former were less digestible. Although the protein concentration in the diets used on the grazing farms (ORG and GRZ) was higher than those used on CNG farms, the protein intake was similar. The results indicated an imbalance between energy and protein due to the low level of energy provided by the ORG diets, suggesting that more microbial protein could be synthesized from the available rumen-degraded dietary nitrogen if rumen-fermentable OM was not limiting. The imbalance between energy and protein led to a reduced amount of total digestible protein reaching the intestine and a lower milk yield per kilogram of CP intake on the ORG farms. In order to improve the protein use efficiency and consequently to reduce the loss of nitrogen to the environment, organic farming should aim to increase the energy content of cattle diets by improving forage quality and formulating rations with more balanced combinations of forage and grain. PMID- 30277190 TI - Self-Perception of Theoretical Knowledge and Practical Skills by Primary Health Care Physicians in Life-Threatening Emergencies. AB - OBJECTIVES: The goal of this study was to find out the training received in Urgent and Emergency Medicine (UEM) by the Primary Health Care (PHC) physicians of Asturias (Spain), as well as their perception of their own theoretical knowledge and practical skills in a series of procedures employed in life threatening emergencies (LTEs), and also to analyze the differences according to the geographical area of their work. METHODS: This was a cross-sectional survey of PHC physicians using an ad hoc survey of a sample of 213 physicians in Asturias regarding their self-perception of theoretical knowledge and practical skills in techniques used in LTEs by areas of work (rural, suburban, and urban). The interview was conducted by mail from April through May 2017. The data processing has used absolute and relative frequencies, as well as central tendency parameters and dispersion parameters. The estimates for the entire population have been made using confidence intervals for the mean of 95%. In the comparison of parameters, the differences between parameters with a probability of error less than five percent (P<.05) have been considered significant. For the comparison of means between the different techniques in the different areas of work, ANOVA was used. RESULTS: With respect to the training of physicians, in general, for managing emergencies, both at the regional level and by areas of work (rural, suburban, and urban), none of the sets analyzed attained five points. By areas of work, it was the suburban region where there was a greater average general level of knowledge. There were significant differences in the average theoretical knowledge and the average practical skills in the procedures studied according to the different areas of work. The greater number of significant differences was between the urban and suburban regions and within the urban area. CONCLUSIONS: It's necessary to ensure an adequate homogeneity of the levels of theoretical knowledge and practical skills of PHC physicians in order to guarantee the equity of provision of health care in emergencies in different geographical areas.

PMID- 30277191 TI - Is Self-Compassion a Worthwhile Therapeutic Target for ICD-11 Complex PTSD (CPTSD)? AB - BACKGROUND: Two 'sibling' disorders have been proposed for the fourthcoming 11th version of the International Classification of Diseases (ICD-11): post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD). Examining psychological factors that may be associated with CPTSD, such as self-compassion, is an important first step in its treatment that can inform consideration of which problems are most salient and what interventions are most relevant. AIMS: We set out to investigate the association between self-compassion and the two factors of CPTSD: the PTSD factor (re-experiencing, avoidance, sense of threat) and the Disturbances in Self Organization (DSO) factor (affect dysregulation, negative self-concept and disturbances in relationships). We hypothesized that self-compassion subscales would be negatively associated with both PTSD and DSO symptom clusters. METHOD: A predominantly female, clinical sample (n = 106) completed self-report scales to measure traumatic life events, ICD-11 CPTSD and self-compassion. RESULTS: Significant negative associations were found between the CPTSD DSO clusters of symptoms and self-compassion subscales, but not for the PTSD ones. Specifically it was also found that self-judgement and common humanity significantly predicted hypoactive affect dysregulation whereas self-judgement and isolation significantly predicted negative self-concept. CONCLUSIONS: Our results indicate that self-compassion may be a useful treatment target for ICD-11 CPTSD, particularly for symptoms of negative self-concept and affect dysregulation. Future research is required to investigate the efficacy and acceptability of interventions that have implicit foundations on compassion. PMID- 30277192 TI - Dietary supplementation of organic or inorganic chromium modulates the immune responses of broilers vaccinated with Avian Influenza virus vaccine. AB - Dietary supplementation with the organic chromium (Cr) has been shown to positively affect the immune function of poultry. However, to our knowledge, no experiment has been done to directly compare the impacts of Cr chloride and chromium picolinate (CrPic) on the immune responses of broilers vaccinated with Avian Influenza (AI) virus vaccine. Therefore, the present experiment was conducted to investigate the effects of supplemental Cr sources (Cr chloride and CrPic) and levels on the growth performance and immune responses of broilers vaccinated with AI virus vaccine so as to provide an effective nutritional strategy for improving immune function of broilers. A total of 432 1-day (d)-old male broiler chicks were used in a 1 plus 2*4 design. Chickens were given either a diet without Cr supplementation (control) or diets supplemented with 0.4, 0.8, 1.6, or 3.2 mg Cr/kg as either Cr chloride or CrPic for 42 d. Compared to the control, dietary Cr supplementation had no effect (P>0.05) on average daily gain, average daily feed intake and gain : feed of broilers during the starter and grower phases, but increased (P<0.05) the relative weights of bursa of fabricius on d 21 and thymus, spleen, or bursa of fabricius on d 42, serum antibody titers against AI virus on d 21, 28, 35 and 42, blood T-lymphocyte transformation rate on d 28 and 42, blood T-lymphocyte percentage on d 42, and serum interleukin-2 contents on d 28. Broilers fed the diets supplemented with the inorganic Cr chloride had higher (P<0.05) weights of thymus, spleen and bursa of fabricius than those fed the diets supplemented with the CrPic on d 42. In addition, broilers fed the diets supplemented with the CrPic had higher (P<0.05) antibody titers against AI virus than those fed the diets supplemented with the inorganic Cr chloride on d 21 and 35. These results indicate that dietary Cr supplementation improved immune responses of broilers vaccinated with AI virus, and the inorganic Cr chloride was more effective than the CrPic in increasing the relative weights of lymphoid organs, however, the CrPic was more effective than the inorganic Cr chloride in enhancing the serum antibody titer against AI virus.

SETTING: Four nursing homes located in Fuzhou, China. PARTICIPANTS: Sixty-two older adults from four nursing homes were selected according to the criteria set for this study. METHOD: Sixty-two older adults were randomly assigned to either the life review group or the control group, and 55 of them completed the study. Twenty-four participants took part in qualitative interviews after the life review program concluded. The Geriatric Depression Scale-15, Rosenberg Self Esteem Scale, and Purpose in Life Test were adopted to measure depression, self esteem, and meaning in life, respectively. RESULTS: The findings indicated that life review can reduce depressive symptoms and may be effective at improving self esteem and meaning in life among Chinese elderly people. More importantly, it revealed that cultural factors such as values, beliefs, and attitudes could interfere with participation in a life review. CONCLUSIONS: A culturally sensitive life review program could be an alternative approach to psychotherapy for promoting mental health in older adults.

AB - : Clinical questionWhat is the diagnostic accuracy of the PECARN, CATCH, and CHALICE clinical decision rules for pediatric head injury, and are the clinical decision rules valid when applied to a novel data set?Article chosenBabl FE, Borland ML, Phillips N, et al. Accuracy of PECARN, CATCH, and CHALICE head injury decision rules in children: a prospective cohort study. Lancet (London, England) 2017;389(10087):2393-402. OBJECTIVES: The primary objective of the study was to determine the diagnostic accuracy and provide external validation for the PECARN, CATCH, and CHALICE clinical decision rules in a clinically homogeneous cohort of children. The secondary objective of this study was to perform a direct comparison of the three decision rules by assessing for the presence of traumatic brain injury (TBI) on computed tomography (CT) or the requirement for neurointervention.

AB - This paper presents a new method for creating and monitoring controlled localized negatively charged regions inside insulators with a scanning electron microscope (SEM). A localized buried charged region is created and observed close to the point where a high voltage primary beam (10 kV) strikes a metal-insulator-silicon specimen. The amount of buried charge within the insulator at any given moment can be dynamically monitored by detecting the appearance of a second peak in the secondary electron (SE) energy spectrum. SE energy spectral signals were obtained through the use of a compact high signal-to-noise energy analyzer attachment that was fitted on to the SEM specimen stage. An electrostatic model, together with Monte Carlo simulations, is presented to explain how the SE charge contrast effect functions. This model is then experimentally confirmed by using the SE energy spectral signal induced by a gallium ion beam inside a dual focused ion beam-SEM instrument.

AB - In 2016, the authors published a paper on music festival fatalities between the years 1999 and 2014 (n=722). In this Special Report, they provide an update on fatalities reported at music festivals globally for the period 2016-2017 (n=201). Using a search strategy designed to capture grey literature and media reports of music festival fatalities, reports of the overall frequency and cause-of-death breakdown for publicly reported, festival-related deaths are recorded. This update shows an increase in the frequency of festival-related fatality reports during the new period, together with an increase in the number of deaths attributable to terror (n=60) and overdose/poisoning (n=41). Drawing conclusions about the cause of this increase is challenging given the growth in Internet use, online media reports, and number of music festivals occurring annually when compared with the previous reporting period. The authors re-emphasize the need for a uniform reporting standard and reliable epidemiological data for fatalities related to music festivals, mass gatherings, and special events.

AB - We describe the case of a patient with severe fever with thrombocytopenia syndrome (SFTS) complicated by SFTS-associated encephalopathy who was successfully treated with 4-day plasma exchange followed by two-time convalescent plasma therapy. During plasma exchange, the plasma cytokines IFN-alpha and IP-10 gradually decreased without change of plasma viral load. However, plasma viral load gradually decreased after convalescent plasma therapy. This case provides important insights for understanding the mechanisms of experimental therapy in severely affected SFTS patients. PMID- 30277198 TI - Do Incarcerated Populations Serve as a Reservoir for Tuberculosis in South Africa? AB - Tuberculosis (TB) prevalence among incarcerated populations is as much as 1,000 times higher than in the general population. This study evaluates whether correctional facilities serve as a reservoir through which TB is transmitted to surrounding communities. Tuberculosis test data were extracted from the South African National Health Laboratory Service database for patients tested for TB between 2005 and 2011. We conducted graphical analysis to assess the relationship of TB rates between incarcerated and non-incarcerated populations over time. We performed generalized linear modeling with a log link function to assess TB risk in communities surrounding correctional facilities, net of confounders. We assessed linkages between incarcerated and non-incarcerated populations over time using Granger causality analysis. Tuberculosis prevalence among incarcerated populations was four times higher than in the general population. Tuberculosis incidence rates in incarcerated and non-incarcerated populations followed similar trends over time. The presence of a correctional facility in a municipality was associated with 34.9% more detected TB cases (confidence interval: 11.6-63.2; P < 0.01), controlling for potential confounders. Detected TB in incarcerated populations did not have predictive power in explaining detected TB rates in the non-incarcerated population after controlling for serial correlation in the time series data. Despite high TB prevalence, trends in correctional facilities do not appear to be driving temporal trends in the general population. However, correctional facilities still act as a TB reservoir that raises the overall TB risk in the vicinity. Intensified TB control policies for correctional facilities, formerly incarcerated individuals, and surrounding communities will reduce TB prevalence overall.

We report the case of a patient whose facial lesion was histopathologically compatible with squamous cell carcinoma and hence programmed for Mohs surgery. However, review of the clinical and epidemiological history led to laboratory diagnosis of cutaneous leishmaniasis, treatment with miltefosine, and complete resolution of the lesion. PMID- 30277200 TI - The Impact of Acquired Immune Deficiency Syndrome Treatment on Tuberculosis Detection at the National Level in South Africa. AB - Human immunodeficiency virus/Tuberculosis (HIV/TB) coinfection is particularly prevalent in South Africa, where TB has been the leading cause of death for more than a decade. The 2004-2008 national rollout of antiretroviral therapy (ART) provides a unique opportunity to examine the population-level impact of ART on the TB epidemic. We performed longitudinal regression analysis to follow the evolution of TB outcomes before and after the introduction of ART using a large data set from the National Health Laboratory Service. This is the first study to produce estimates of the impact of the ART rollout by exploiting staggered timing and geographic variation in the rollout. After ART became available in a health facility, 3.7% (P < 0.0001) more patients were tested for TB and 3.2% (P < 0.0001) more received repeat testing; however, there was a steep rise in testing before the introduction of ART. Although the number of TB-positive patients increased by 4.3% (P = 0.0002) in the first year post-ART, the TB rate among tested patients fell by 2% points (8%, P = 0.001) after 2 years. Sputum smear testing declined relative to more technologically advanced diagnostics post-ART. Antiretroviral therapy availability increased the attention to TB screening and drew new patients into the health-care system. Small increases in the numbers of repeat patients are indicative of retention in care. The decline in TB rates post ART suggests that the reduction in TB risk due to improved immune functioning and health-care contact likely outweighed the increased TB risk because of the longer lifespan of ART initiators. PMID- 30277201 TI - Case Report: Acute Transverse Myelitis after Zika Virus Infection. AB - We report here one case of Zika virus (ZIKV) infection associated with auto immunity directed against the central nervous system in a Brazilian woman who developed acute transverse myelitis 9 days after recovery from an acute episode of fever with generalized erythema. Imaging of the spinal cord showed an elongated area on the T1-T10 level with gadolinium uptake. The diagnostic of the ZIKV infection was confirmed by cerebrospinal fluid and serum analysis. This patient had serum positivity for autoantibodies against myelin oligodendrocyte glycoprotein (MOG), a specific antibody against the myelin sheath. We propose that a direct central nervous system infection by ZIKV could lead to a specific auto-immunity against MOG protein. PMID- 30277202 TI - Impact of a Nonfatal Dengue Episode on Disability-Adjusted Life Years: A Systematic Analysis. AB - As dengue causes about 4,000 symptomatic nonfatal episodes for every dengue death globally, quantitative disability assessments are critical to assess the burden of dengue and the cost-effectiveness of dengue control interventions. This systematic analysis of disability or quality of life lost from a symptomatic nonfatal dengue episode combined a systematic literature review, statistical modeling, and probabilistic sensitivity analyses. We conceptualized a dengue episode as having two phases: acute and persistent symptoms. Our estimates for the acute phase, consisting of onset and recovery periods and defined as the first 20 days (0.054 year), were based on literature review. We searched PubMed, POPLINE, EconLit, Google Scholar, scientific conferences, and other sources, for "dengue" plus "quality of life" or related terms. From 4,322 initial entries, six met our criteria (original studies with empirical data). The median disability adjusted life year (DALY) burden for the acute phase was 0.011 (95% certainty interval [CI]: 0.006-0.015) for ambulatory episodes, 0.015 (CI: 0.010-0.020) for hospitalized episodes, and 0.012 (CI: 0.006-0.019) overall. Using literature reviews about persistent dengue, we estimated that 34% of episodes experienced persistent symptoms with a median duration of symptoms of 0.087 (CI: 0.040-0.359) year, which resulted in median DALYs of 0.019 (CI: 0.008-0.082). Thus, the overall median DALY burden was 0.031 (CI: 0.017-0.092) for ambulatory episodes, 0.035 (CI: 0.024-0.096) for hospitalized episodes, and 0.032 (CI: 0.018-0.093) overall. Our dengue-specific burden of a dengue episode was 2.1 times the 2013 Global Burden of Disease estimate. These literature-based estimates provide an empirical summary for policy and cost-effectiveness analyses. PMID- 30277203 TI - Sensitivity of the Point-of-Care Circulating Cathodic Antigen Urine Cassette Test for Diagnosis of Schistosoma mansoni in Low-Endemicity Settings in Cote d'Ivoire. AB - The sensitivity of a point-of-care circulating cathodic antigen (POC-CCA) urine cassette test for diagnosis of Schistosoma mansoni in low-endemicity settings is poorly understood. We conducted a cross-sectional survey in 14 villages in western Cote d'Ivoire and diagnosed children aged 9-12 years for schistosomiasis. Two stool samples were subjected to triplicate Kato-Katz thick smears each for diagnosis of S. mansoni, whereas a single urine sample was examined by POC-CCA for S. mansoni, filtration for Schistosoma haematobium, and reagent strip for microhematuria. According to the Kato-Katz technique, we found 45 out of 681 children positive for S. mansoni (6.6%) with a mean intensity among infected children of 72.2 eggs per gram of stool. Point-of-care circulating cathodic antigen revealed a prevalence of S. mansoni of 33.0% when trace results were considered positive and 12.4% when trace results were considered negative. Eggs of S. haematobium were found in eight participants (1.2%), whereas the prevalence of microhematuria was 13.5%. A single POC-CCA urine cassette test revealed a several-fold higher prevalence of S. mansoni than multiple Kato-Katz thick smears in this low-endemicity area. Our findings have important ramifications for choosing an appropriate diagnostic tool in low-endemic areas that might be targeted for elimination.

AB - Age-specific population immunity to many vaccine-preventable diseases can be measured using serological surveys. However, stand-alone serological surveys are infrequently conducted in low- and middle-income countries because of costs, operational challenges, and potential high refusal rates for blood collection. Nesting a serosurvey within a household cluster survey may overcome some of these challenges. We share lessons learned from nesting a serosurvey within a measles and rubella vaccination post-campaign coverage evaluation survey (PCES). In 15 of the 26 PCES clusters in Southern Province, Zambia, we collected dried blood spots from 581 participants aged 9 months and older. Household participation rates for the main PCES were higher in the serosurvey clusters (86%) than PCES-only clusters (71%), suggesting that a serosurvey can be successfully integrated without adversely affecting PCES participation. Among households that participated in the PCES, 80% also participated in the serosurvey and 86% of individuals available in the household provided a blood sample for the serosurvey. Substantial planning and coordination, additional staff training, and community mobilization were critical to the success of the serosurvey. Most challenges stemmed from using different data collecting tools and teams for the serosurvey and PCES. A more efficient design would be to fully integrate the serosurvey by adding blood collection and additional questions to the PCES. PMID- 30277205 TI - Case Report: Space-Occupying Lesion in the Liver Related to Preprandial Hunger and Hepatic Visceral Larva Migrans. AB - Visceral larva migrans (VLM) is one of the clinical syndromes of human toxocariasis. We report a case of hepatic VLM presenting preprandial malaise and epigastric discomfort in a 58-year-old woman drinking raw roe deer blood. The imaging studies of the abdomen showed a 74-mm hepatic mass featuring hepatic VLM. Anti-Toxocara canis IgG was observed in enzyme-linked immunosorbent assay (ELISA) and western blot. Despite anthelmintic treatment, the patient complained of newly developed cough and skin rash with severe eosinophilia. Hepatic lesion increased in size. The patient underwent an open left lobectomy of the liver. After the surgery, the patient was free of symptoms such as preprandial malaise, epigastric discomfort, cough, and skin rash. Laboratory test showed a normal eosinophilic count at postoperative 1 month, 6 months, 1 year, and 4 years. The initial optical density value of 2.55 of anti-T. canis IgG in ELISA was found to be negative (0.684) at postoperative 21 months. Our case report highlights that a high degree of clinical suspicion for hepatic VLM should be considered in a patient with a history of ingestion of raw food in the past, presenting severe eosinophilia and a variety of symptoms which reflect high worm burdens. Symptom remission, eosinophilia remission, and complete radiological resolution of lesions can be complete with surgery. PMID- 30277206 TI - Absence of Plasmodium falciparum K13 Propeller Domain Polymorphisms among Field Isolates Collected from the Brazilian Amazon Basin between 1984 and 2011. AB - Artemisinin resistance, presently confined to Southeast Asia and associated with mutations in the Plasmodium falciparum K13 (PfK13) propeller domain, represents a serious threat to global malaria control. This study aimed to provide baseline information for future artemisinin resistance surveillance, by analyzing the PfK13 propeller domain in P. falciparum field isolates collected from the Brazilian Amazon Basin between 1984 and 2011. A total of 152 P. falciparum mono infections were assessed, of which 118 (78%) were collected before and 34 (22%) after the introduction of artemisinin-based combination therapy (ACT) in 2006. An 849-base pair fragment encoding the PfK13 propeller was amplified by nested PCR and sequenced in both directions. The sequences were compared with the reference sequence of P. falciparum 3D7. All samples showed wild-type sequences, thus, no mutations were observed. The results are in agreement with other recent reports and do not provide evidence for presence of PfK13 propeller domain polymorphisms associated with artemisinin resistance among P. falciparum field isolates in the Brazilian Amazon Basin neither before nor after the implementation of ACT.

AB - Strongyloides stercoralis is the main etiological agent of human strongyloidiasis. Severe strongyloidiasis is commonly associated to alcoholism, corticostereoid use, and human T cell lymphotropic virus type 1 (HTLV-1) coinfection. Herein, we report a case of a 13-year-old boy coinfected with S. stercoralis and HTLV-1, excreting several parasitic forms in the stool. The parasitological examination of his feces showed a large amount of filariform (about 3,000 larvae per gram of feces) and rhabditiform larvae (about 2,000 larvae per gram of feces). In addition, free-living adult females (about 50 parasites per gram of feces) and eggs (about 60 eggs per gram of feces) were detected. The main laboratory findings pointed to high IgE levels (228 UI/mL) and eosinophila (11.6%). The patient was treated with three courses of ivermectin (200 ug/kg twice, 2 weeks apart), achieving the parasitological cure. An increase of about 19 times in IL-17 level was observed following the parasitological cure, in addition to a decrease in the white blood cell, eosinophil counts, and IgE levels. This is the first case report, to our knowledge, in which an S. stercoralis adult free-living female was described in human feces and where an increase in IL-17 levels after Strongyloides treatment in a HTLV-1 coinfected individual was observed. This finding raises the need for further studies about IL-17 immunomodulation in S. stercoralis and HTLV-1 coinfected patients.

AB - Careful design of the green spaces in cities will benefit both wild animals and humans. PMID- 30277211 TI - Mammal communities are larger and more diverse in moderately developed areas. AB - Developed areas are thought to have low species diversity, low animal abundance, few native predators, and thus low resilience and ecological function. Working with citizen scientist volunteers to survey mammals at 1427 sites across two development gradients (wild-rural-exurban-suburban-urban) and four plot types (large forests, small forest fragments, open areas and residential yards) in the eastern US, we show that developed areas actually had significantly higher or statistically similar mammalian occupancy, relative abundance, richness and diversity compared to wild areas. However, although some animals can thrive in suburbia, conservation of wild areas and preservation of green space within cities are needed to protect sensitive species and to give all species the chance to adapt and persist in the Anthropocene. PMID- 30277214 TI - Bulgaria: Health System Review. AB - This analysis of the Bulgarian health system reviews developments in its organization and governance, health financing, health care provision, health reforms and health system performance. With the 2015 National Health Strategy 2020 at its core, there have been ambitious reform plans to introduce more decentralization, strategic purchasing and integrated care into the Bulgarian social health insurance system. However, the main characteristics of the Bulgarian health system, including a high level of centralization and a single payer to administer social health insurance, remain intact and very few reforms have been implemented (for example, the introduction of health technology assessment). There are multiple reasons for this, of which political fragility and stakeholder resistance are among the most important. Overall, Bulgaria marked notable progress on some health indicators (for example, life expectancy and infant mortality) but generally progress lags behind EU averages. What is more, the system has not been effective in reducing amenable mortality, as reflected in the unsteady improvement patterns in mortality due to malignant neoplasms. This is despite an increase in total health expenditure as a percentage of gross domestic product to 8.2% in 2015. The overall high out-of-pocket spending (47.7% of total health spending in 2015) has been growing and is increasingly worrisome. It evidences the low degree of financial protection by the Bulgarian social health insurance system and exacerbates the already considerable inequities along socioeconomic and regional fault lines. For instance, there are regional imbalances of medical professionals, which are more concentrated in urban areas, and accessibility to physicians is further deteriorating, especially in rural areas. Current reforms have to tackle these challenges and build consensus among stakeholders of the health system to unlock the standstill. PMID- 30277212 TI - Cryo-EM structure of respiratory complex I at work. AB - Mitochondrial complex I has a key role in cellular energy metabolism, generating a major portion of the proton motive force that drives aerobic ATP synthesis. The hydrophilic arm of the L-shaped ~1 MDa membrane protein complex transfers electrons from NADH to ubiquinone, providing the energy to drive proton pumping at distant sites in the membrane arm. The critical steps of energy conversion are associated with the redox chemistry of ubiquinone. We report the cryo-EM structure of complete mitochondrial complex I from the aerobic yeast Yarrowia lipolytica both in the deactive form and after capturing the enzyme during steady state activity. The site of ubiquinone binding observed during turnover supports a two-state stabilization change mechanism for complex I. PMID- 30277210 TI - An essential Staphylococcus aureus cell division protein directly regulates FtsZ dynamics. AB - Binary fission has been well studied in rod-shaped bacteria, but the mechanisms underlying cell division in spherical bacteria are poorly understood. Rod-shaped bacteria harbor regulatory proteins that place and remodel the division machinery during cytokinesis. In the spherical human pathogen Staphylococcus aureus, we found that the essential protein GpsB localizes to mid-cell during cell division and co-constricts with the division machinery. Depletion of GpsB arrested cell division and led to cell lysis, whereas overproduction of GpsB inhibited cell division and led to the formation of enlarged cells. We report that S. aureus GpsB, unlike other Firmicutes GpsB orthologs, directly interacts with the core divisome component FtsZ. GpsB bundles and organizes FtsZ filaments and also stimulates the GTPase activity of FtsZ. We propose that GpsB orchestrates the initial stabilization of the Z-ring at the onset of cell division and participates in the subsequent remodeling of the divisome during cytokinesis. PMID- 30277215 TI - Austria: Health System Review. AB - This analysis of the Austrian health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. Two major reforms implemented in 2013 and 2017 are among the main issues today. The central aim of the reforms that put in place a new governance system was to strengthen coordination and cooperation between different levels of government and self-governing bodies by promoting joint planning, decision-making and financing. Yet despite these efforts, the Austrian health system remains complex and fragmented in its organizational and financial structure. The Austrian population has a good level of health. Life expectancy at birth is above the EU average and low amenable mortality rates indicate that health care is more effective than in most EU countries. Yet, the number of people dying from cardiovascular diseases and cancer is high compared to the EU-28 average. Tobacco and alcohol represent the major health risk factors. Tobacco consumption has not declined over the last decade like in most other EU countries and lies well above the EU-28 average. In terms of performance, the Austrian health system provides good access to health care services. Austrias residents report the lowest levels of unmet needs for medical care across the EU. Virtually all the population is covered by social health insurances and enjoys a broad benefit basket. Yet, rising imbalances between the numbers of contracted and non-contracted physicians may contribute to social and regional inequalities in accessing care. The Austrian health system is relatively costly. It has a strong focus on inpatient care as characterized by high hospital utilization and imbalances in resource allocation between the hospital and ambulatory care sector. The ongoing reforms therefore aim to bring down publicly financed health expenditure growth with a global budget cap and reduce overutilization of hospital care. Efficiency of inpatient care has improved over the reform period but the fragmented financing between the inpatient and ambulatory sector remain a challenge. Current reforms to strengthen primary health care are an important step to further shift activities out of the large and costly hospital sector and improve skill mix within the health workforce. PMID- 30277213 TI - Redox-dependent rearrangements of the NiFeS cluster of carbon monoxide dehydrogenase. AB - The C-cluster of the enzyme carbon monoxide dehydrogenase (CODH) is a structurally distinctive Ni-Fe-S cluster employed to catalyze the reduction of CO2 to CO as part of the Wood-Ljungdahl carbon fixation pathway. Using X-ray crystallography, we have observed unprecedented conformational dynamics in the C cluster of the CODH from Desulfovibrio vulgaris, providing the first view of an oxidized state of the cluster. Combined with supporting spectroscopic data, our structures reveal that this novel, oxidized cluster arrangement plays a role in avoiding irreversible oxidative degradation at the C-cluster. Furthermore, mutagenesis of a conserved cysteine residue that binds the C-cluster in the oxidized state but not in the reduced state suggests that the oxidized conformation could be important for proper cluster assembly, in particular Ni incorporation. Together, these results lay a foundation for future investigations of C-cluster activation and assembly, and contribute to an emerging paradigm of metallocluster plasticity. PMID- 30277216 TI - Spain: Health System Review. AB - This analysis of the Spanish health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. Overall health status continues to improve in Spain, and life expectancy is the highest in the European Union. Inequalities in self-reported health have also declined in the last decade, although long standing disability and chronic conditions are increasing due to an ageing population. The macroeconomic context in the last decade in the country has been characterized by the global economic recession, which resulted in the implementation of health system-specific measures addressed to maintain the sustainability of the system. New legislation was issued to regulate coverage conditions, the benefits package and the participation of patients in the National Health System funding. Despite the budget constraints linked to the economic downturn, the health system remains almost universal, covering 99.1% of the population. Public expenditure in health prevails, with public sources accounting for over 71.1% of total health financing. General taxes are the main source of public funds, with regions (known as Autonomous Communities) managing most of those public health resources. Private spending, mainly related to out-of pocket payments, has increased over time, and it is now above the EU average. Health care provision continues to be characterized by the strength of primary care, which is the core element of the health system; however, the increasing financing gap as compared with secondary care may challenge primary care in the long-term. Public health efforts over the last decade have focused on increasing health system coordination and providing guidance on addressing chronic conditions and lifestyle factors such as obesity. The underlying principles and goals of the national health system continue to focus on universality, free access, equity and fairness of financing. The evolution of performance measures over the last decade shows the resilience of the health system in the aftermath of the economic crisis, although some structural reforms may be required to improve chronic care management and the reallocation of resources to high-value interventions. PMID- 30277217 TI - Estonia: Health System Review. AB - This analysis of the Estonian health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. In 2017, the Estonian government took the historic step of expanding the revenue base of the health system, which has been a longstanding challenge. However, in terms of percentage of GDP it remains a small increase and long-term financial sustainability could still pose a problem. That said, if these additional funds are invested wisely, they could play a positive role in further improving the health system. Indeed, although Estonia has made remarkable progress on many health indicators (e.g. the strongest gains in life expectancy of all EU countries, strongly falling amenable mortality rates), there are opportunities for improvements. They include overcoming the large health disparities between socioeconomic groups, improving population coverage, developing a comprehensive plan to tackle workforce shortages, better managing the growing number of people with (multiple) noncommunicable diseases and further reaping the benefits of the e-health system, especially for care integration and clinical decision-making. Also in terms of quality, large strides have been made but the picture is mixed. Avoidable hospital admissions are among the lowest in Europe for asthma and chronic obstructive pulmonary disease (COPD), about average for congestive heart failure and diabetes, but among the worst for hypertension. Moreover, the 30-day fatality rates for acute myocardial infarction and stroke are among the worst in the EU. These outcomes suggest substantial room to further improve service quality and care coordination. The new NHP, which is currently being revised will be play a crucial role in the success of future reform efforts. PMID- 30277218 TI - Laser-induced ultrafast transport and demagnetization at the earliest time: first principles and real-time investigation. AB - It is generally believed that there are at least two ways to use an ultrafast laser pulse to demagnetize a magnetic sample. One is to directly photo demagnetize the system through spin-orbit coupling (SOC), and the other is to utilize ultrafast hot electron transport without SOC. The challenge is that these two processes are entangled on the same time scale. While the experimental results have been inconclusive, theoretical investigations are even scarcer, beyond those earlier studies based on spin superdiffusion. For instance, we do not even know how fast electrons move under laser excitation and how far they move. Here we carry out a first-principles time-dependent calculation to investigate how fast electrons actually move under laser excitation and how large the electron transport affects demagnetization on the shortest time scale. To take into account the transport effect, we implement the intraband transition in our theory. In the bulk fcc Ni, we find the effect of the spin transport on the demagnetization is extremely small, no more than 1%. The collective electron velocity in Ni is 0.4 A fs-1, much smaller than the Fermi velocity, and the collective displacement is no more than 0.1 A. But this does not mean that electrons do not travel fast; instead we find that electron velocities at two opposite crystal momenta cancel each other. We follow the Gamma-X line and find a huge dispersion in the velocities in the crystal momentum space. In the Fe/W(1 1 0) thin film, the overall demagnetization is larger than Ni, and the Fermi velocity is higher than Ni. However, the effect of the spin transport is still small in the Fe/W(1 1 0) thin film. Based on our numerical results and existing experimental findings, we propose a different mechanism that can explain two latest experimental results. Our finding sheds new light on the effect of ballistic transport on demagnetization.

AB - : Neural engineering research is actively engaged in optimizing the robustness of sensorimotor rhythms (SMR)-brain-computer interface (BCI) to boost its potential real-world use. OBJECTIVE: This paper investigates two vital factors in efficient and robust SMR-BCI design-algorithms that address subject-variability of optimal features and neurophysiological factors that correlate with BCI performance. Existing SMR-BCI research using electroencephalogram (EEG) to classify bilateral motor imagery (MI) focus on identifying subject-specific frequency bands with most discriminative motor patterns localized to sensorimotor region. APPROACH: A novel strategy to further optimize BCI performance by taking into account the variability of discriminative spectral regions across various EEG channels is proposed in this paper. MAIN RESULTS: The proposed technique results in a significant ([Formula: see text]) increase in average ([Formula: see text]) classification accuracy by [Formula: see text] accompanied by a considerable reduction in number of channels and bands. The session-to-session transfer variation in spectro-spatial patterns using proposed algorithm is investigated offline and classification performance of the optimized BCI model is successfully evaluated in an online SMR-BCI. Further, the effective prediction of SMR-BCI performance with physiological indicators derived from multi-channel resting state EEG is demonstrated. The results indicate that the resting state activation patterns such as entropy and gamma power from pre-motor (fronto-central) and posterior (parietal and centro-parietal) areas, and beta power from posterior (centro-parietal) areas estimate BCI performance with minimum error. These patterns, strongly related to BCI performance, may represent certain cognitive states during rest. SIGNIFICANCE: Findings reported in this paper imply the need for subject-specific modelling of BCI and the prediction of BCI performance using multi-channel rest-state parameters, to ensure enhanced BCI performance.

AB - The continuous miniaturization of electronic components and the emergence of nano biotechnology has opened new perspectives to monitor electrical activities at the single cell level. Here, we describe the creation of very high surface-to-volume ratio passive devices (vertical nanowire probes) using large-scale fabrication process, allowing to follow the electrical activity of mammalian neurons. Based on conventional silicon processing, the silicon nanowires were silicided in platinum in order to improve their electrochemical performances and to guarantee their biocompatibility. Very high signal to noise ratio was achieved (up to 2000) when measuring spontaneous action potentials. Moreover, this bio-platform was used to record the impact of various bio-chemical and electrical stimulations on neuronal activity. To conclude, this study proposes a thorough comparison of the characteristics and performances of these new nanowire-based nanoprobes with the main alternative systems published up to now. PMID- 30277221 TI - Peripheral dose around a mobile linac for intraoperative radiotherapy: radiation protection aspects. AB - The aim of this work is to analyse the scattered radiation produced by the mobile accelerator Mobetron 1000. To do so, detailed Monte Carlo simulations using two different codes, Penelope2008 and Geant4, were performed. Measurements were also done. To quantify the attenuation due to the internal structures, present in the accelerator head, on the scattered radiation produced, some of the main structural shielding in the Mobetron 1000 has been incorporated into the geometry simulation. Results are compared with measurements. Some discrepancies between the calculated and measured dose values were found. These differences can be traced back to the importance of the radiation component due to low energy scattered electrons. This encouraged us to perform additional calculations to separate the role played by this component. Ambient dose equivalent, H*(10), outside of the operating room (OR) has been evaluated using Geant4. H*(10) has been measured inside and outside the OR, being its values compatible with those reported in the literature once the low energy electron component is removed. With respect to the role played by neutrons, estimations of neutron H*(10) using Geant4 together with H*(10) measurements has been performed for the case of the 12 MeV electron beam. The values obtained agree with the experimental values existing in the literature, being much smaller than those registered in conventional accelerators. This study is a useful tool for the clinical user to investigate the radiation protection issues arising with the use of these accelerators in ORs without structural shielding. These results will also enable to better fix the maximum number of treatments that could be performed while insuring adequate radiological protection of workers and public in the hospital. PMID- 30277222 TI - [Cellular Model Based on Laser Microsurgery of Cell Spheroids to Study the Repair Process]. AB - In this study, modern techniques of laser microsurgery of cell spheroids have been used to developa new simple, reproducible model for studying the mechanisms of repair and regeneration in vitro. Nanosecondlaser pulses were applied to perform a microdissection of the outer and the inner zones of the spheroidsfrom dermal fibroblasts. To achieve effective dissection and preservation of spheroid viability, the optimalparameters were chosen: 355 nm wavelength, 100 Hz frequency, 2 ns pulse duration, laser pulses in the rangeof 7-9 MU J. After microdissection, we observed injury of the spheroids : the edges of the wound surface openedand the angular opening reached a value of more than 180 degrees . As early as during the first hour after spheroidmicrodissection with laser radiation, the surviving cells changed their shape: cells on the spheroid surface anddirectly in the damaged area became rounded. One day after microdissection, the structure of the spheroidsbegan to partially recover, the cells in the surface layers began to take the original flattened shape; debris ofdead damaged cells and their fragments was gradually cleared from the spheroid composition. In the proposedmodel, the first data on stimulation of structure recovery of injured spheroids from dermal fibroblasts with aP199 synthetic polypeptide, which is used in cosmetology for the initiation of antiaging and regenerativeeffects in the skin, were received. After microdissection, recovery of the spheroids structure with a few surfacelayers of flattened imbricated arranged cells and polygonal cells of the inner zone in the presence of P199 peptidewas faster than in the control group, and was completed within 7 days, presumably due to the remodelingof the survived cells. PMID- 30277223 TI - Automated Unsupervised Behavioral State Classification using Intracranial Electrophysiology. AB - OBJECTIVE: Automated behavioral state classification in intracranial EEG (iEEG) recordings may be beneficial for iEEG interpretation and quantifying sleep patterns to enable behavioral state dependent neuromodulation therapy in next generation implantable brain stimulation devices. Here, we introduce a fully automated unsupervised framework to differentiate between awake (AW), sleep (N2), and slow wave sleep (N3) using intracranial EEG (iEEG) only and validated with expert scored polysomnography. APPROACH: Data from eight patients undergoing evaluation for epilepsy surgery (age 40+/-11, 3 female) with intracranial depth electrodes for iEEG monitoring were included. Spectral power features (0.1 - 235Hz) spanning several frequency bands from a single electrode were used to classify behavioral states of patients into AW, N2, and N3. RESULTS: Overall, classification accuracy of 94%, with 94% sensitivity and 93% specificity across eight subjects using multiple spectral power features from a single electrode was achieved. Classification performance of N3 sleep was significantly better (95%, sensitivity 95%, specificity 93%) than that of the N2 sleep phase (87%, sensitivity 78%, specificity 96%). SIGNIFICANCE: Automated, unsupervised, and robust classification of behavioral states based on iEEG data is possible, and it is feasible to incorporate these algorithms into future implantable devices with limited computational power, memory, and number of electrodes for brain monitoring and stimulation. PMID- 30277224 TI - Endotoxin Contributes to Artificial Loosening of Prostheses Induced by Titanium Particles. AB - BACKGROUND Aseptic loosening of orthopedic implants caused by wear particles is a major cause of joint replacement failure. However, the mechanism of aseptic loosening has not yet been defined. The present study explored whether endotoxin adherent on the titanium (Ti) particles contributes to aseptic loosening. MATERIAL AND METHODS Limulus amebocyte lysate detection was conducted to detect the levels of endotoxin adhered to the Ti particles. A mouse air pouches model was established and mice were divided into 4 groups and injected with phosphate buffered saline (PBS) or Ti particles suspensions (0.1, 1, 10 mg/mL), following detection of the number of macrophages and the level of endotoxin. Scanning electron microscopy (SEM) was used to characterize the microstructures of Ti particles adhered with endotoxin. RESULTS In vitro experiments showed that the level of endotoxin adhered to the Ti particles was significantly increased after adding LPS back to these "endotoxin-free" particles. In vivo experiments showed that Ti particles injection significantly increased the number of macrophages and the level of endotoxin. CONCLUSIONS In conclusion, these results suggest that adherent endotoxin may play an important role in aseptic loosening induced by Ti particles. PMID- 30277225 TI - [High-pressure injection of paint into the hand: a severe injury that should not be underestimated]. AB - : High-pressure injection into the hand causes a small skin lesion but severe subcutaneous tissue damage, which can result in permanent functional loss or amputation. Urgent and appropriate treatment is decisive. We present the case of an industrial painter who injected oil-based paint with a high-pressure gun into his left index finger. He was admitted to Accidents and Emergencies, where tetanus prophylaxis and antibiotic therapy were adminis-tered. Then, within four hours of his arrival at the hospital, the patient was brought to the operating room for surgical debridement. A year after the injury the finger's active and passive range of motion was complete, although paling of the skin together with hypersensitivity and dysfunction occurred on exposure to cold. The severity of these lesions, even if their initial appearance is benign, must be recognized and an immediate surgical debridement of the entire ischemic tissue should be performed, because delay in treatment is associated with higher rates of complication. KEYWORDS: High-pressure injuries. Paint injection. Hand. MANAGEMENT: PMID- 30277226 TI - [Prevalence and typology of patients susceptible of palliative care deceased at home]. AB - BACKGROUND: Identification of patients susceptible to palliative care (SPC) in the community is essential for improving their clinical management. The objective is to explore the SPC population and their typology of illness, according to sex. METHODS: Cross-sectional study, performed on the population of Malaga who died at home during 2015. Association between type of patient (SCP or identified as palliative by inclusion in the integrated care process (ICP)). Age, sex and type of disease were analyzed with Chi square and t-Student's test. RESULTS: Of 950 patients attended to after dying at home, 417 (43.9%) were SCP and, of them, 277 (66,4%) were included in the ICP. Males were more frequent in both populations (55.6 and 59.9%, respectively, p=0,26), with mean ages 78.6 and 76.2, respectively (p=0.01). The most frequent diseases in SCP patients were: cancer (61.9%), dementia and Alzheimer (19.9%), chronic ob-structive pulmonary disease (COPD) (6.2%) and heart failure (4.1%). People with cancer were more frequently included in the ICP (86.8%), while those with dementia and Alzheimer, COPD and Parkinson were less frequently included (20.5, 38.4 and 0.4% respectively). By sex, men suffered more from cancer and women from dementia. Percentage of inclusion in ICP was similar for men and women, stratified by disease. CONCLUSIONS: Almost half of the people who died at home are SCP although only two out of three are identified as such. Cancer is the most frequent SCP disease and the easiest one to identify, largely affecting men. Three out of four people with dementia died without being identified as PC, and they are mainly women. PMID- 30277227 TI - [Patient satisfaction in the Spanish National Health System]. AB - BACKGROUND: Determine which key indicators of the Spanish National Health Service (NHS) influence patient satisfaction with the Spanish NHS and physicians (family doctors and specialists). METHOD: The mean for each indicator for each autonomous community, published by the Ministry of Health, Social Services and Equality, corresponding to the years 2005 to 2014, was related to patient satisfaction by means of multiple linear regression. RESULTS: Patient satisfaction with the NHS was ascertained at 57.32%, with general practitioners at 54.45% and specialist doctors at 55.11%. In the three types of satisfaction, the number of specialist doctors, hospital admissions and in-hospital mortality had a positive and significant influence, while the number of surgical interventions had a negative influence. The greater use of computerized tomography equipment and the hospital infection rate had a negative effect on satisfaction with the NHS and with specialist physicians, while the percentage of outpatient surgery had a positive effect. The average hospital stay shows a negative relationship with satisfaction with family doctors and specialists. CONCLUSIONS: Health policies should consider an increase in the number of medical specialists, favour ambulatory surgery, facilitate hospital treatment, monitor the effectiveness of surgical interventions, control hospital infections and moderate the prescription of drugs through the use of alternatives in order to increase patient satisfaction. PMID- 30277228 TI - Subtle changes in network composition impact the biodistribution and tumor accumulation of nanogels. AB - We studied the effect of subtle changes in side-chain chemistry and labelling with near infrared fluorophores of nanogels (NGs) prepared from thiolated poly(glycidol) on in vivo biodistribution in mice bearing human breast tumor xenografts. The stability and amphiphilic character of the side chain as well as labelling clearly influenced tumor targeting and overall biodistribution. PMID- 30277229 TI - Conformation of bis-nitroxide polarizing agents by multi-frequency EPR spectroscopy. AB - The chemical structure of polarizing agents critically determines the efficiency of dynamic nuclear polarization (DNP). For cross-effect DNP, biradicals are the polarizing agents of choice and the interaction and relative orientation of the two unpaired electrons should be optimal. Both parameters are affected by the molecular structure of the biradical in the frozen glassy matrix that is typically used for DNP/MAS NMR and likely differs from the structure observed with X-ray crystallography. We have determined the conformations of six bis nitroxide polarizing agents, including the highly efficient AMUPol, in their DNP matrix with EPR spectroscopy at 9.7 GHz, 140 GHz, and 275 GHz. The multi frequency approach in combination with an advanced fitting routine allows us to reliably extract the interaction and relative orientation of the nitroxide moieties. We compare the structures of six bis-nitroxides to their DNP performance at 500 MHz/330 GHz. PMID- 30277230 TI - Transition between tangential and co-axial liquid crystalline honeycombs in the self-assembly of Y-shaped bolapolyphiles. AB - p-Terphenyl based Y-shaped bolapolyphiles self-assemble into liquid crystalline honeycombs with co-axial organization of the pi-conjugated rods around columns filled by alkyl sidechains. In this new hexagonal honeycomb with P6/mmm symmetry the orientation of the pi-conjugated rods is perpendicular to the tangential honeycombs formed at lower temperature or with longer chain length. PMID- 30277231 TI - Rapid determination of binding parameters of chitin binding domains using chitin coated quartz crystal microbalance sensor chips. AB - Chitin present in fungal cell walls has been considered as a diagnostic polymer for the detection of fungal infections. Chitin staining can be achieved with different dyes such as Calcofluor white or Congo red, but these methods have not entered into clinical routine diagnosis due to problems with sensitivity and specificity. More accurate detection can be achieved using chitin binding domains (CBDs) from a large variety of naturally occurring proteins that specifically interact with chitin. The chitin binding properties of most of these proteins have not yet been determined, because chitin is an insoluble fibrillar material rendering accurate determination of chitin binding kinetics challenging. Here we report a quartz crystal microbalance with dissipation monitoring (QCM-D) based method to determine binding constants of CBDs on chitin-coated gold surfaces. For this purpose, chitin was trimethylsilylated and coated onto the sensor chips. After desilylation, regular fibril-like structures with a typical center-to center spacing of 85 nm were observed by atomic force microscopy. Using different experimental conditions and data evaluation methods for QCM-D measurements, we determined kon and koff and calculated the KD values for binding of a recombinant CBD from Bacillus circulans chitinase A1. Depending on the evaluation method, the KD values ranged between 0.6 and 2.5 MUM. The obtained KD values were in good agreement with those measured for other bacterial CBDs usually ranging between 1 to 10 MUM. Hence, we propose that the experimental approach developed in this study can be applied to determine yet unknown binding affinities of various CBDs from different origin. PMID- 30277232 TI - Optical transient absorption experiments reveal the failure of formal kinetics in diffusion assisted electron transfer reactions. AB - The ultimate goal of chemical kinetics is to understand why a given reaction is fast or not. To this end it is necessary to count on robust and experimentally well tested theories. One of the difficulties, long recognized in the study of bimolecular reactions, is the role of the molecular displacement, i.e. diffusion. Nonetheless the field is still lacking a compelling amount of case studies contrasting physical models to experiments. By performing transient absorption experiments on the photo-induced electron transfer reaction between perylene and N,N-dimethylaniline in liquid solutions over many orders of magnitude in time, we try to understand the factors determining the kinetics and yields of the full photocycle. We present a method to overcome potential pitfalls in the extraction of the relevant quantities, the transient populations, from the experimental data due to the changes in band shapes and positions. The results are compared to simulations of two different theories: a reaction-diffusion approach based on the encounter theories, and a formal kinetic scheme. We conclude that while the former explains the observed trends in the kinetics with quencher concentration and viscosity exceptionally well, the latter fails. Moreover the analysis of the data with the assistance of encounter theory unveils effects that otherwise would pass unnoticed. This approach and its results exemplify the path to follow in other condensed media whenever diffusion is involved. PMID- 30277233 TI - Scaffold mediated gene knockdown for neuronal differentiation of human neural progenitor cells. AB - The use of human induced pluripotent stem cell-derived neural progenitor cells (hiPSC-NPCs) is an attractive therapeutic option for damaged nerve tissues. To direct neuronal differentiation of stem cells, we have previously developed an electrospun polycaprolactone nanofiber scaffold that was functionalized with siRNA targeting Re-1 silencing transcription factor (REST), by mussel-inspired bioadhesive coating. However, the efficacy of nanofiber-mediated RNA interference on hiPSC-NPCs differentiation remains unknown. Furthermore, interaction between such cell-seeded scaffolds with injured tissues has not been tested. In this study, scaffolds were optimized for REST knockdown in hiPSC-NPCs to enhance neuronal differentiation. Specifically, the effects of two different mussel inspired bioadhesives and transfection reagents were analyzed. Scaffolds functionalized with RNAiMAX Lipofectamine-siREST complexes enhanced the differentiation of hiPSC-NPCs into TUJ1+ cells (60% as compared to 22% in controls with scrambled siNEG after 9 days) without inducing high cytotoxicity. When cell-seeded scaffolds were transplanted to transected spinal cord organotypic slices, similar efficiency in neuronal differentiation was observed. The scaffolds also supported the migration of cells and neurite outgrowth from the spinal cord slices. Taken together, the results suggest that this scaffold can be effective in enhancing hiPSC-NPC neuronal commitment by gene-silencing for the treatment of injured spinal cords. PMID- 30277234 TI - Site-specific one-pot triple click labeling for DNA and RNA. AB - We report site-specific triple click labeling for DNA and RNA in a one-pot setup by performing inverse electron demand Diels-Alder reaction and strain-promoted and copper catalyzed click reactions sequentially. Our methodology can be applied to long and short nucleic acids alike, and could have broader potential for labeling other (bio-)molecules. PMID- 30277235 TI - Super long-life potassium-ion batteries based on an antimony@carbon composite anode. AB - A highly stable Sb based anode material of well-confined Sb@graphene@carbon (Sb@G@C) was developed for high performance PIBs. The Sb@G@C electrode exhibits a reversible capacity of 474 mA h g-1 at 100 mA g-1 (second charge), an outstanding long cycle stability over 800 cycles with a capacity retention as high as 72.3% and an excellent rate performance. PMID- 30277236 TI - Monomeric thorium chalcogenolates with bipyridine and terpyridine ligands. AB - Thorium chalcogenolates Th(ER)4 react with 2,2'-bipyridine (bipy) to form complexes with the stoichiometry (bipy)2Th(ER)4 (E = S, Se; R = Ph, C6F5). All four compounds have been isolated and characterized by spectroscopic methods and low-temperature single crystal X-ray diffraction. Two of the products, (bipy)2Th(SC6F5)4 and (bipy)2Th(SeC6F5)4, crystallize with lattice solvent, (bipy)2Th(SPh)4 crystallizes with no lattice solvent, and the selenolate (bipy)2Th(SePh)4 crystallizes in two phases, with and without lattice solvent. In all four compounds the available volume for coordination bounded by the two bipy ligands is large enough to allow significant conformational flexibility of thiolate or selenolate ligands. 77Se NMR confirms that the structures of the selenolate products are the same in pyridine solution and in the solid state. Attempts to prepare analogous derivatives with 2,2',6',2''-terpyridine (terpy) were successful only in the isolation of (terpy)(py)Th(SPh)4, the first terpy compound of thorium. These materials are thermochromic, with color attributed to ligand-to-ligand charge transfer excitations. PMID- 30277238 TI - Theoretical studies on the mechanism of Pd2+-catalyzed regioselective C-H acylation of azoxybenzenes with alpha-oxocarboxylic acids. AB - The reaction mechanism of the Pd2+-catalyzed regioselective C(sp2)-H acylation of azoxybenzenes with alpha-oxocarboxylic acids has been studied by density functional theory (DFT) calculations. This reaction mechanism involves five major steps: C-H activation, deprotonation, decarboxylation, reductive elimination and oxidation. Our calculation results indicate that the N-coordinated pathway is better than the O-coordinated pathway, which can be interpreted by distortion interaction analysis of the C-H bond activation transition states. Furthermore, we also suggest that the C-H bond acylation of aryl 1 is more favorable than that of aryl 2, which can be attributed to the fact that five-membered ring transition states are more favorable than four-membered ring transition states and the ON group has positive charge. PMID- 30277240 TI - Colloidal porous gold nanoparticles. AB - Porous Au nanostructures have attracted much attention for their wide uses as catalysts, sensors, actuators and surface-enhanced Raman scattering (SERS) substrates. The synthesis of porous Au nanostructures has mainly relied on dealloying approaches, which generally involve high-temperature treatment to form alloys and subsequent harsh chemical etching. Herein we report on an ambient wet chemistry method for the synthesis of colloidal porous Au nanoparticles. The synthesis takes advantage of the growth of Au on PbS nanocrystals accompanied by the etching of PbS by the growth solution. The obtained porous Au nanoparticles display a SERS enhancement factor of (1.23 +/- 0.10) * 107 on the individual particles under off-resonance excitation and a catalytic activity that is several times those of previously reported porous Au particles and porous Au sheets. Our results will have high impact on many SERS-based analytical and biomedical applications and on the field of Au-based catalysis. PMID- 30277243 TI - Influence of polymeric electrets on the performance of derived hybrid perovskite based photo-memory devices. AB - Organic-inorganic hybrid perovskite has become one of the most important photoactive materials owing to its intense light-harvesting property as well as its facile solution processability. Besides its photovoltaic applications, a novel photo-programmed transistor memory was recently developed based on the device architecture of a floating-gate transistor memory using a polymer/perovskite blend as the gate dielectric with the non-volatile memory characteristics of decent light response, applicable On/Off current ratio, and long retention time. In this study, we further clarify the influence of polymer matrix selection on the photo-response and memory properties of derived hybrid perovskite-based photo-memory devices. Four different host polymers, polystyrene (PS), poly(4-vinylphenol) (PVPh), poly(methyl methacrylate) (PMMA), and poly(methacrylic acid) (PMAA), were systematically investigated for comparison herein. This revealed that dissimilar chemical interactions existed between the host polymers and perovskite, resulting in the distinct memory behavior of the derived photo-memory devices, attributable to the different morphologies of the hybrid dielectric layers and the different sizes of the distributed perovskite nanoparticles (NPs). The photo-response behavior and the resultant On/Off current ratio increased as the size of the embedded perovskite NPs decreased, due to the enhanced photo-induced charge transfer across the dielectric/pentacene interface, benefiting from the better confinement effect of perovskite NPs in the polymer matrix. These results demonstrate the influence of perovskite NP aggregation at the dielectric/pentacene interface on the resultant memory behavior of the newly developed photo-memory device. PMID- 30277241 TI - A two-dimensional fingerprint nanoprobe based on black phosphorus for bio-SERS analysis and chemo-photothermal therapy. AB - Flake-shaped nanohybrids based on black phosphorus (BP) have been developed as multifunctional theranostic nanoplatforms for drug delivery, phototherapy and bioimaging. In this work, we report a facile strategy for fabrication of black phosphorus-Au nanoparticle hybrids (BP-AuNPs), which reveal an extraordinary near infrared (NIR) photothermal transduction efficiency and drug delivery capacity. The applications of the nanocomposites as therapeutic agents for high-performance chemo-photothermal tumor therapy are accomplished in vitro and in vivo. BP-AuNPs also exhibit wonderful surface-enhanced Raman scattering (SERS) activity under NIR laser excitation with a low Raman background, allowing BP-AuNPs to be used as a promising two-dimensional (2D) fingerprint nanoprobe for bio-SERS analysis. The cellular component identification and label-free live-cell bioimaging based on this type of 2D SERS substrate are generally investigated, which open up promising new perspectives in nanomedicine, including diagnosis, imaging and therapy. PMID- 30277244 TI - A coupled effect of dehydration and electrostatic interactions on selective ion transport through charged nanochannels. AB - Selective ion transport is an essential feature of biological ion channels. Due to the subnanometer size and negatively charged surface of ion channels, the ion selectivity is affected by both dehydration effects and electrostatic interactions. Their coupled effect on selective ion transport, however, has been elusive. Here, using molecular dynamics simulations, we study ion (Li+ and Mg2+) transport through subnanometer carbon nanotubes (CNTs) with varying charge densities. Our results indicate that the dehydration effect governs the ionic transport at low surface charge densities, hence the nanochannel shows a selectivity for Li+ ions. In contrast, the nanochannel switches to a selectivity for Mg2+ ions as the electrostatic interaction between the cations and the negatively charged wall dominates the transport at high surface charge densities. PMID- 30277245 TI - Photochemical strategies for the green synthesis of ultrathin Au nanosheets using photoinduced free radical generation and their catalytic properties. AB - Two-dimensional gold nanosheets represent a class of materials with excellent chemical and structural properties, which are often prepared using a template or toxic CO in organic solvents. Here, we report methylene blue (MB) radicals as a reducing agent to grow freestanding hexagonal ultrathin Au nanosheets with well tuned thicknesses in water. This is the first time that carbon organic radicals have been used as a reducing agent in metal nanosheet synthesis. Notably, no template is used throughout the synthesis process, and the yield of Au nanosheets is very high. It is found that MB is decisive in the growth of Au nanosheets because no Au nanosheets are obtained in the absence of MB with the same reaction parameters. The resulting nanosheets exhibit excellent catalytic activity during H2O2 decomposition to generate nontoxic O2. Thus, folic acid-conjugated oxygen generating nanosheets could detect cancer cells in serum samples with high sensitivity through pressure signals. Furthermore, the nanosheets exhibit highly efficient activity and selectivity toward the hydrogenation of alpha,beta unsaturated aldehydes. We anticipate that using MB radicals for the high-yield synthesis of 2D materials in this unique system has demonstrated their effectiveness and provides a green alternative route for producing other 2D nanomaterials. PMID- 30277246 TI - Altered zinc balance in the Atp7b-/- mouse reveals a mechanism of copper toxicity in Wilson disease. AB - Wilson disease (WD) is an autosomal recessive disorder caused by mutation in the ATP7B gene that affects copper transport in the body. ATP7B mutation damages copper transporter function, ultimately resulting in excessive copper accumulation and subsequent toxicity in both the liver and brain. Mechanisms of copper toxicity, however, are not well defined. The Atp7b-/- mouse model is well characterized and presents a hepatic phenotype consistent with WD. In this study, we found that the untreated Atp7b-/- mice accumulate approximately 2-fold excess hepatic zinc compared to the wild type. We used targeted transcriptomics and proteomics to analyze the molecular events associated with zinc and copper accumulation in the Atp7b-/- mouse liver. Altered gene expression of Zip5 and ZnT1 zinc transporters indicated a transcriptional homeostatic response, while increased copper/zinc ratios associated with high levels of metallothioneins 1 and 2, indicated altered Zn availability in cells. These data suggest that copper toxicity in Wilson disease includes effects on zinc-dependent proteins. Transcriptional network analysis of RNA-seq data reveals an interconnected network of transcriptional activators with over-representation of zinc-dependent and zinc-responsive transcription factors. In the context of previous research, these observations support the hypothesis that mechanisms of copper toxicity include disruption of intracellular zinc distribution in liver cells. The translational significance of this work lies in oral zinc supplementation in treatment for WD, which is thought to mediate protective effects through the induction of metallothionein synthesis in the intestine. This work indicates broader impacts of altered zinc-copper balance in WD, including global transcriptional responses and altered zinc balance in the liver. PMID- 30277248 TI - Single atom alloy catalyst for SO3 decomposition: enhancement of platinum catalyst's performance by Ag atom embedding. AB - Recently, single atom alloy catalysts (SAA) have shown improved catalytic activity in numerous catalytic reactions. However, to date, single atom alloy (SAA) catalyst is not available for SO3 decomposition reaction, which is a key reactions in the hydrogen economy. Using state of the art density functional theory, we report a novel single Ag atom alloy Pt catalyst in the sub-nanometer length scale (AgPt9@Al2O3) showing superior catalytic behavior for SO3 decomposition. It was found that alloying the alumina-supported platinum nanocluster with a single Ag atom lowers the activation barrier for S-O bond breaking by more than 50% in comparison with the pristine platinum counterpart. Activation barrier for AgPt9@Al2O3 catalyst is 0.52 eV, which is the lowest of any platinum based catalyst reported so far. At variance with pure Pt10@Al2O3, which tries to detach from the support during decomposition reaction, single atom alloy (SAA) nanocluster AgPt9@Al2O3 enhances binding with support, thus strengthening sintering resistance. Notably, influence of single Ag atom is also observed at larger length scale, i.e., at Pt(111) slab, where single Ag atom substituted surface Ag1Pt(111) shows ~30% reduction in activation barrier in contrast to a pristine surface. Single Ag atom works in bifunctional mode as it not only reduces the activation barrier, but also simultaneously weakly adsorbs the reaction product SO2, signifying relatively easier desorption and better recyclability. Deeper location of silver d-electrons and lesser electronegativity of silver is responsible for the better performance of single Ag atom alloyed Pt catalyst. We strongly believe that these remarkable results will open new avenues for future designing and fabrication of cost-effective catalysts for SO3 decomposition. PMID- 30277249 TI - Molecules on rails: friction anisotropy and preferential sliding directions of organic nanocrystallites on two-dimensional materials. AB - Two-dimensional (2D) materials are envisaged as ultra-thin solid lubricants for nanomechanical systems. So far, their frictional properties at the nanoscale have been studied by standard friction force microscopy. However, lateral manipulation of nanoparticles is a more suitable method to study the dependence of friction on the crystallography of two contacting surfaces. Still, such experiments are lacking. In this study, we combine atomic force microscopy (AFM) based lateral manipulation and molecular dynamics simulations in order to investigate the movements of organic needle-like nanocrystallites grown by van der Waals epitaxy on graphene and hexagonal boron nitride. We observe that nanoneedle fragments - when pushed by an AFM tip - do not move along the original pushing directions. Instead, they slide on the 2D materials preferentially along the needles' growth directions, which act as invisible rails along commensurate directions. Further, when the nanocrystallites were rotated by applying a torque with the AFM tip across the preferential sliding directions, we find an increase of the torsional signal of the AFM cantilever. We demonstrate in conjunction with simulations that both, the significant friction anisotropy and preferential sliding directions are determined by the complex epitaxial relation and arise from the commensurate and incommensurate states between the organic nanocrystallites and the 2D materials. PMID- 30277250 TI - Evolution of 3D nanoporosity and morphology in selectively dealloying ternary Au55Cu25Si20 metallic glass ribbon with enhanced alcohol electro-oxidation performance. AB - Current fabrication methods of nanoporous gold (NPG) mainly rely on dealloying Ag Au binary crystalline precursors, typically Ag65Au35, with the "dealloying threshold" or "parting limit" above 55 at%. Here we report a simple chemical dealloying process, through selective dissolution of one element from a Au55Cu25Si20 metallic glass ribbon with low 'parting limit', and a novel peculiar three-dimensional 'cone shaped protrusion' nanoporous structure which has never been reported before. In this structure, a metastable gold silicide formed in the initial dealloying stage was decomposed into gold nanoparticles and amorphous SiOx in the later coarsening stage. Our finding provides insights into the underlying relationship between 'parting limit' and atomic level structure of metallic glass. Comprehensive discussions on the porosity evolution stages as well as the correlation between the porous 'cone shaped protrusion' development and potential energy landscape are made in this report. The fabricated 3D NPG also exhibited excellent electro-oxidation catalytic ability attributed to the high density of low-coordinated atomic sites provided by the gold particle inside of 'cone shaped protrusion'.

AB - An ultra-sensitive and transparent piezoresistive pressure sensor based on a sea urchin shaped metal nanoparticle (SSNP)-polyurethane (PU) composite with microdome arrays is successfully fabricated for the first time. The piezoresistive pressure sensor with microdome arrays was prepared using a nanoimprinting process based on an intermediate polymer substrate (IPS) replica mold. It showed a superior sensitivity (71.37 kPa-1) and a high optical transmittance (77.7% at 550 nm) due to the effective quantum tunneling effect even at small concentrations of conductive SSNP filler (6 mg mL-1). The high performance characteristics of the piezoresistive pressure sensor are attributed to the geometric effects of the microdome structure, especially the stress concentration at small contact spots and the deformation of the contact area. The piezoresistive pressure sensor with microdome arrays also exhibited a fast response/relaxation time (30 ms), ultra-low pressure detection (4 Pa), and excellent long-term stability under harsh conditions. In addition, the effectiveness of the piezoresistive pressure sensors in various sensing applications including sensing mapping, human arterial pulse monitoring, and the detection of muscle movement is also successfully demonstrated. It is anticipated that this novel transparent pressure sensor based on a SSNP-PU composite with microdome arrays will be a key component in the development of integrated transparent sensing applications.

AB - Portable visual detection systems for environmental monitoring or diagnostic purposes are eagerly anticipated in low-resource settings. Inexpensive device requirements and visualization are key challenges for the development of any portable analysis system. We report herein a new strategy for developing portable rapid ion detection technology by the coupling of topochemical polymerization and supramolecular (SM) self-assembly. The rapid sol-gel or gel-sol phase transition of SM hydrogels has been widely applied for the detection of many important analytes including metal ions. However, one problem that remains is the difficulty inaccurately quantifying the degree of self-assembly with the naked eye. To address this problem, we designed a diacetylene-grafted peptide that can be polymerized following self-assembly into a hydrogel triggered by zinc ions. Before adding zinc ions, the molecules dissolved well in aqueous solution and arranged randomly, and were unable to be polymerized through UV light irradiation. After mixing with zinc ions, the peptide chelated with zinc ions immediately and self-assembled into a SM hydrogel. The molecules arranged orderly and could be easily polymerized through irradiation of a hand-held UV lamp in less than 2 minutes. The hydrogel showed a quick and sharp chromatic change from colorless to dark blue, which allowed the quantification of self-assembly (i.e. concentration of zinc ions) with the naked eye. In addition, the monomers were insensitive to light, pH and temperature changes, which is a highly desired characteristic in practical applications. PMID- 30277254 TI - Preparation of fluorinated PCL porous microspheres and a super-hydrophobic coating on fabrics via electrospraying. AB - In this study, fluorinated polycaprolactone (PCL) block polymers with different fluorine contents were synthesized via atom transfer radical polymerization (ATRP). An electrospraying technique was used to prepare fluorinated PCL microspheres with different microstructures. In contrast to the golf ball shape of unmodified PCL microspheres displaying porous pits on the surface, block polymer PCL-PTFOA(2 h) and PCL-PTFOA(6 h) microsphere surfaces displayed regular honeycomb-like pore structures. Thermally induced and evaporation-induced phase separations are proposed as the main mechanisms involved in the formation of the porous microstructures. The micro-phase separation between the two blocks of the fluorinated PCL copolymer is another factor that promoted the uniform collapse on the microsphere surface and the formation of its rugged wall. The surface roughness of the porous microspheres significantly improved their hydrophobicity, generating coating contact angles on aluminium foil substrates that measured as high as 162.4 +/- 1.5 degrees , which revealed that the surfaces were super hydrophobic. Lastly, cotton fabric was directly coated with the fluorinated polymer microspheres via electrospraying, resulting in super-hydrophobic surfaces and CAs reaching 160.0 +/- 1.3 degrees . The results demonstrate that electrospraying is a simple, innovative and cost-effective method for preparing polymer microspheres with controllable microstructures for fabric coating applications. PMID- 30277255 TI - Fabrication and understanding of Cu3Si-Si@carbon@graphene nanocomposites as high performance anodes for lithium-ion batteries. AB - Besides silicon's low electronic conductivity, another critical issue for using silicon as the anode for lithium-ion batteries (LIBs) is the dramatic volume variation (>300%) during lithiation/delithiation processes, which can lead to rapid capacity fading and poor rate capability, thereby hampering silicon's practical applications in batteries. To mitigate these issues, herein, we report our findings on the design and understanding of a self-supported Cu3Si Si@carbon@graphene (Cu3Si-SCG) nanocomposite anode. The nanocomposite is composed of Cu3Si-Si core and carbon shell with core/shell particles uniformly encapsulated by graphene nanosheets anchored directly on a Cu foil. In this design, the carbon shell, the highly elastic graphene nanosheet, and the formed conductive and inactive Cu3Si phase in Si serve as buffer media to suppress volume variation of Si during lithiation/delithiation processes and to facilitate the formation of a stable solid electrolyte interface (SEI) layer as well as to enable good transport kinetics. Chemomechanical simulation results quantitatively coincide with the in situ TEM observations of volume expansion and provide process details not seen in experiments. The optimized Cu3Si-SCG nanocomposite anode exhibits good rate performance and delivers reversible capacity of 483 mA h g-1 (based on the total weight of Cu3Si-SCG) after 500 cycles with capacity retention of about 80% at high current density of 4 A g-1, rendering the nanocomposite a desirable anode candidate for high-performance LIBs. PMID- 30277256 TI - Novel pi-extended hybrid xanthene dyes with two spirolactone rings for optoelectronic and biological applications. AB - The design, synthesis, and photophysical properties of organic fluorophores have attracted considerable research interest due to the utility of these compounds for various optoelectronic, analytical, and biological applications. In this study, we synthesized two novel pi-extended red-emitting hybrid xanthene dyes, each of which has two spirolactone rings and combines a seminaphthofluorescein moiety and a seminaphthorhodafluor moiety in a single molecule. The photophysical properties of the dyes in methanol in the presence of acid, base, and metal cations were investigated. Mono-ring-opened seminaphthofluorescein and seminaphthorhodafluor forms of the dyes could be obtained by the addition of OH- or H+, respectively. Owing to the changes in the absorbance spectra of the mono ring-opened forms induced by addition of H+ and OH-, the dyes could perform simultaneously the functions of an XOR gate and an INHIBIT gate, with the absorbances at 510 and 560 nm as outputs, respectively, and could act as half subtractors with H+ and OH- as inputs. Furthermore, stepwise ring-opening could be induced by Hg2+ ions in methanol. In water, the dyes existed in double-ring opened forms that emitted deep-red fluorescence and were mitochondria-targetable, suggesting that these chromophores might be useful as fluorescence tracers in biological applications. Because the absorption and fluorescence properties of these fluorophores can be regulated via their two spirolactone rings, we expect that these compounds will find utility in various optoelectronic, analytical, and biological applications. PMID- 30277257 TI - Skeletal malformations of Meox1-deficient zebrafish resemble human Klippel-Feil syndrome. AB - Klippel-Feil syndrome is a congenital vertebral anomaly, which is characterised by the fusion of at least two cervical vertebrae and a clinically broad set of symptoms, including congenital scoliosis and elevated scapula (Sprengel's deformity). Klippel-Feil syndrome is associated with mutations in MEOX1. The zebrafish mutant choker (cho) carries a mutation in its orthologue, meox1. Although zebrafish is being increasingly employed as fidelitous models of human spinal disease, the vertebral column of Meox1-deficient fish has not been assessed for defects. Here, we describe the skeletal defects of meox1cho mutant zebrafish utilising alizarin red to stain bones and chemical maceration of soft tissue to detect fusions in an unbiased manner. Obtained data reveal that meox1cho mutants feature aspects of a number of described symptoms of patients who suffer from Klippel-Feil syndrome and have mutations in MEOX1. These include vertebral fusion, congenital scoliosis and an asymmetry of the pectoral girdle, which resembles Sprengel's deformity. Thus, the meox1cho mutant zebrafish may serve as a useful tool to study the pathogenesis of the symptoms associated with Klippel-Feil syndrome. PMID- 30277258 TI - Low self-esteem, entrapment, and reason for living: A moderated mediation model of suicidal ideation. AB - Adolescent suicidal ideation has become a top public health concern. It is thus significant to explore both risk and protective factors of adolescent suicidal ideation. The present study tested a moderated mediation model of suicidal ideation in a sample of Chinese adolescents. Chinese adolescents of 1074 (54.2% females, aged between 11 and 18 years) completed questionnaires assessing self esteem, entrapment, reason for living, and suicidal ideation. We found that entrapment mediated the association between low self-esteem and suicidal ideation. The association between entrapment and suicidal ideation was moderated by reason for living. Findings of this study may expand our understanding of the development of suicidal ideation, and facilitate future research exploring the interplay of risk and protective factors of suicidality. Clinical implications of these findings were also discussed. PMID- 30277259 TI - Disparities in the management of paediatric splenic injury. AB - BACKGROUND: The non-operative management of splenic injury in children is recommended widely, and is possible in over 95 per cent of episodes. Practice appears to vary between centres. METHODS: The Trauma Audit and Research Network (TARN) database was interrogated to determine the management of isolated paediatric splenic injuries in hospitals in England and Wales. Rates of non operative management, duration of hospital stay, readmission and mortality were recorded. Management in paediatric surgical hospitals was compared with that in adult hospitals. RESULTS: Between January 2000 and December 2015 there were 574 episodes. Children treated in a paediatric surgical hospital had a 95.7 per cent rate of non-operative management, compared with 75.5 per cent in an adult hospital (P < 0.001). Splenectomy was done in 2.3 per cent of children in hospitals with a paediatric surgeon and in 17.2 per cent of those treated in an adult hospital (P < 0.001). There was a significant difference in the rate of non operative management in children of all ages. There was some improvement in non operative management in adult hospitals in the later part of the study, but significant ongoing differences remained. CONCLUSION: The management of children with isolated splenic injury is different depending on where they are treated. The rate of non-operative management is lower in hospitals without a paediatric surgeon present. PMID- 30277260 TI - Enhanced contrast in X-ray microtomographic images of the membranous labyrinth using different X-ray sources and scanning modes. AB - The vestibular system, located in the inner ear, plays a crucial role in balance and gaze stabilisation by sensing head movements. The interconnected tubes with membranous walls of the vestibular system are located in the skull bone (the 'membranous labyrinth'). Unfortunately, these membranes are very hard to visualise using three-dimensional (3D) X-ray imaging techniques. This difficulty arises due to the embedment of the membranes in the dense skull bone, the thinness of the membranes, and the small difference in X-ray absorption between the membranes and the surrounding fluid. In this study, we compared the visualisation of very small specimens (lizard heads with vestibular systems smaller than 3 mm) by X-ray computed micro-tomography (MUCT) based on synchrotron radiation and conventional sources. A visualisation protocol using conventional X ray MUCT would be very useful thanks to the ease of access and lower cost. Careful optimisation of the acquisition parameters enables detection of the membranes by using MUCT scanners based on conventional microfocus sources, but in some cases a low contrast-to-noise ratio (CNR) prevents fast and reliable segmentation of the membranes. Synchrotron radiation MUCT proved to be preferable for the visualisation of the small samples with very thin membranes, because of their high demands for spatial and contrast resolution. The best contrast was obtained by using synchrotron radiation MUCT working in phase-contrast mode, leading to up to twice as high CNRs than the best conventional MUCT results. The CNR of the synchrotron radiation MUCT scans was sufficiently high enough to enable the construction of a 3D model by the means of semi-automatic segmentation of the membranous labyrinth. Membrane thickness was found to range between 2.7 and 36.3 MUm. Hence, the minimal membrane thickness was found to be much smaller than described previously in the literature (between 10 and 50 MUm). PMID- 30277261 TI - Malignant ovarian germ cell tumours in the post-menopausal population. AB - BACKGROUND: Malignant ovarian germ cell tumours (MOGCT) are uncommon in the general population and very rare in post-menopausal women. AIMS: To evaluate the demographics, treatment and survival of post-menopausal women with MOGCT treated at the Queensland Centre for Gynaecological Cancer (QCGC) and compare these with pre-menopausal women. MATERIALS AND METHODS: Retrospective analysis was performed of the QCGC database from January 1981 to February 2017. The disease course of post-menopausal women was compared with pre-menopausal women affected by MOGCT over the same period and compared with the world literature. RESULTS: There were six post-menopausal women with MOGCT treated at the QCGC compared with 166 pre menopausal women. In the post-menopausal group of women, there was no mortality directly attributed to germ cell ovarian disease compared with 10 (6.0%) women in the pre-menopausal group. CONCLUSIONS: Malignant ovarian germ cell tumours are a very rare condition in post-menopausal women. Despite some suggestion in the world literature that survival outcomes are worse in this population, this was not found in our study. PMID- 30277262 TI - Autism-linked CHD gene expression patterns during development predict multi-organ disease phenotypes. AB - Recent large-scale exome sequencing studies have identified mutations in several members of the CHD (Chromodomain Helicase DNA-binding protein) gene family in neurodevelopmental disorders. Mutations in the CHD2 gene have been linked to developmental delay, intellectual disability, autism and seizures, CHD8 mutations to autism and intellectual disability, whereas haploinsufficiency of CHD7 is associated with executive dysfunction and intellectual disability. In addition to these neurodevelopmental features, a wide range of other developmental defects are associated with mutants of these genes, especially with regards to CHD7 haploinsufficiency, which is the primary cause of CHARGE syndrome. Whilst the developmental expression of CHD7 has been reported previously, limited information on the expression of CHD2 and CHD8 during development is available. Here, we compare the expression patterns of all three genes during mouse development directly. We find high, widespread expression of these genes at early stages of development that gradually becomes restricted during later developmental stages. Chd2 and Chd8 are widely expressed in the developing central nervous system (CNS) at all stages of development, with moderate expression remaining in the neocortex, hippocampus, olfactory bulb and cerebellum of the postnatal brain. Similarly, Chd7 expression is seen throughout the CNS during late embryogenesis and early postnatal development, with strong enrichment in the cerebellum, but displays low expression in the cortex and neurogenic niches in early life. In addition to expression in the brain, novel sites of Chd2 and Chd8 expression are reported. These findings suggest additional roles for these genes in organogenesis and predict that mutation of these genes may predispose individuals to a range of other, non-neurological developmental defects. PMID- 30277263 TI - Magnetic resonance imaging findings in dogs with orbital inflammation. AB - OBJECTIVES: To describe MRI features of canine retrobulbar inflammation, their association with clinical findings and outcome and to assess the value of MRI in detecting orbital foreign bodies. MATERIALS AND METHODS: Clinical records of dogs with confirmed (23 of 31) and suspected (eight of 31) retrobulbar inflammation that underwent low field MRI studies were analysed retrospectively. RESULTS: Of the 31 dogs included in the study there was abscessation in 19. Extraocular myositis (27 of 31) was concurrent with strabismus in three cases. Of 25 patients with exophthalmos, 14 had concurrent optic nerve swelling and, of these, five had permanent loss of vision. There was no vision loss in patients without nerve swelling. One case of suspected retinal detachment on MRI was confirmed clinically. Extensive abnormal contrast enhancement in the temporalis, masseter and pterygoideus muscles was associated with facial (n=3) and trigeminal nerve deficits (n=1). Three patients with inflammation extending into the nasal cavity and frontal sinus (one of 31) or meningeal contrast enhancement (two of 31), showed optic and oculomotor nerve deficits. On MRI a foreign body was not visible in 20 of 31 case or "appeared likely" in 11 of 31 dogs. A foreign body was found at surgery in one case. CLINICAL SIGNIFICANCE: MRI outlines the extent of retrobulbar inflammation. Clinical findings were associated with imaging findings. MRI overestimated the presence of foreign bodies.

Profiling the cervicovaginal microbiome, therefore, is instrumental for vaccine development. We show that the microbiome profile captured by cervicovaginal lavage is comparable to samples obtained by vaginal swabs. Thus, lavage may serve as a sampling strategy in NHP vaccine studies. PMID- 30277265 TI - Magnetic resonance fingerprinting: a technical review. AB - Multiparametric quantitative imaging is gaining increasing interest due to its widespread advantages in clinical applications. Magnetic resonance fingerprinting is a recently introduced approach of fast multiparametric quantitative imaging. In this article, magnetic resonance fingerprinting acquisition, dictionary generation, reconstruction, and validation are reviewed. PMID- 30277266 TI - Chemical profiling by LC-MS/MS and HPLC fingerprint combined with chemometrics and simultaneous determination of 16 characteristic ingredients for the quality consistency evaluation of Shaoyao-Gancao Decoction. AB - In this paper, to evaluate the effect of the region of origin on the quality consistency of Shaoyao-Gancao Decoction (SGD), the SGD fingerprint was developed for the first time. Chemometric methods including similarity analysis, hierarchical clustering analysis and principal component analysis were employed to study the quality consistency of SGD. Meanwhile, high-performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometry was applied for comprehensive analysis of SGD and 93 compounds were tentatively characterized. Furthermore, a high-performance liquid chromatography method with multi-wavelength switching for simultaneous determination of 16 characteristic ingredients comprising gallic acid, oxypaeniflorin, albiflorin, paeoniflorin, liquiritin apioside, liquiritin, isoliquiritin apioside, galloylpaeoniflorin, 1,2,3,4,6-penta-O-galloyl-d galactopyranose (PGG), ononin, isoliquiritin, liquiritigenin, benzoylpaeoniflorin, glycyrrhizic acid, isoliquiritigenin and formononetin, was established. All 16 analytes show excellent linearity (R2 >= 0.9990) with recoveries ranging from 96.58 to 104.61% and limits of detection and quantification of 0.022-0.291 and 0.037-0.635 MUg/mL, respectively. Finally, it was successfully applied to determine 15 batches of SGD. The results of our research indicate that different regions of origin have a significant effect on the quality consistency of SGD, and its fingerprint combined with chemometrics and multi-ingredient determination comprise an efficient and reliable approach for quality consistency evaluation. PMID- 30277267 TI - Multiband RF pulse design for realistic gradient performance. AB - PURPOSE: Simultaneous multi-slice techniques are reliant on multiband RF pulses, for which conventional design strategies result in long pulse durations, lengthening echo-times so lowering SNR for spin-echo imaging, and lengthening repetition times for gradient echo sequences. Pulse durations can be reduced with advanced RF pulse design methods that use time-variable selection gradients. However, the ability of gradient systems to reproduce fast switching pulses is often limited and can lead to image artifacts when ignored. We propose a time efficient pulse design method that inherently produces gradient waveforms with lower temporal bandwidth. METHODS: Efficient multiband RF pulses with time variable gradients were designed using time-optimal VERSE. Using VERSE directly on multiband pulses leads to gradient waveforms with high temporal bandwidth, whereas VERSE applied first to singleband RF pulses and then modulated to make them multiband, significantly reduces this. The relative performance of these approaches was compared using simulation and experimental measurements. RESULTS: Applying VERSE before multiband modulation was successful at removing out-of-band slice distortion. This effectively removes the need for high frequency modulation in the gradient waveform while preserving the benefit of time-efficiency inherited from VERSE. CONCLUSION: We propose a time-efficient RF pulse design that produces gradient pulses with lower temporal bandwidth, reducing image artifacts associated with finite temporal bandwidth of gradient systems. PMID- 30277268 TI - A regional bolus tracking and real-time B1 calibration method for hyperpolarized 13C MRI. AB - PURPOSE: Acquisition timing and B1 calibration are two key factors that affect the quality and accuracy of hyperpolarized 13C MRI. The goal of this project was to develop a new approach using regional bolus tracking to trigger Bloch-Siegert B1 mapping and real-time B1 calibration based on regional B1 measurements, followed by dynamic imaging of hyperpolarized 13C metabolites in vivo. METHODS: The proposed approach was implemented on a system which allows real-time data processing and real-time control on the sequence. Real-time center frequency calibration upon the bolus arrival was also added. The feasibility of applying the proposed framework for in vivo hyperpolarized 13C imaging was tested on healthy rats, tumor-bearing mice and a healthy volunteer on a clinical 3T scanner following hyperpolarized [1-13C]pyruvate injection. Multichannel receive coils were used in the human study. RESULTS: Automatic acquisition timing based on either regional bolus peak or bolus arrival was achieved with the proposed framework. Reduced blurring artifacts in real-time reconstructed images were observed with real-time center frequency calibration. Real-time computed B1 scaling factors agreed with real-time acquired B1 maps. Flip angle correction using B1 maps results in a more consistent quantification of metabolic activity (i.e, pyruvate-to-lactate conversion, kPL). Experiment recordings are provided to demonstrate the real-time actions during the experiment. CONCLUSIONS: The proposed method was successfully demonstrated on animals and a human volunteer, and is anticipated to improve the efficient use of the hyperpolarized signal as well as the accuracy and robustness of hyperpolarized 13C imaging. PMID- 30277269 TI - Scan-specific robust artificial-neural-networks for k-space interpolation (RAKI) reconstruction: Database-free deep learning for fast imaging. AB - PURPOSE: To develop an improved k-space reconstruction method using scan-specific deep learning that is trained on autocalibration signal (ACS) data. THEORY: Robust artificial-neural-networks for k-space interpolation (RAKI) reconstruction trains convolutional neural networks on ACS data. This enables nonlinear estimation of missing k-space lines from acquired k-space data with improved noise resilience, as opposed to conventional linear k-space interpolation-based methods, such as GRAPPA, which are based on linear convolutional kernels. METHODS: The training algorithm is implemented using a mean square error loss function over the target points in the ACS region, using a gradient descent algorithm. The neural network contains 3 layers of convolutional operators, with 2 of these including nonlinear activation functions. The noise performance and reconstruction quality of the RAKI method was compared with GRAPPA in phantom, as well as in neurological and cardiac in vivo data sets. RESULTS: Phantom imaging shows that the proposed RAKI method outperforms GRAPPA at high (>=4) acceleration rates, both visually and quantitatively. Quantitative cardiac imaging shows improved noise resilience at high acceleration rates (rate 4:23% and rate 5:48%) over GRAPPA. The same trend of improved noise resilience is also observed in high resolution brain imaging at high acceleration rates. CONCLUSION: The RAKI method offers a training database-free deep learning approach for MRI reconstruction, with the potential to improve many existing reconstruction approaches, and is compatible with conventional data acquisition protocols. PMID- 30277271 TI - Reduction of lipid contamination in MR spectroscopy imaging using signal space projection. AB - PURPOSE: Lipid contamination can complicate the metabolite quantification in MR spectroscopic imaging (MRSI). In addition to various experimental methods demonstrated to be feasible for lipid suppression, the postprocessing method is beneficial in the flexibility of applications. In this study, the signal space projection (SSP) algorithm is proposed to suppress the lipid signal in the MRSI. METHODS: The performance of lipid suppression using SSP and SSP combined with the Papoulis-Gerchberg (PG) algorithm (PG+SSP) is examined in 2D MRSI data and the results were compared with outer volume saturation (OVS) methods. Up to 10 lipid spatial components were extracted by SSP from lipid signals in the range of 0.8~1.5 ppm. RESULTS: Our results show that most lipid signals were found in the first 4 to 5 components and that lipid signals on the spectra can be suppressed using 4 to 5 components. Metabolites concentrations were quantified using LCModel. Two regions of interest (ROIs) were manually selected on the peripheral and inner brain regions. The quantification of metabolites in terms of fitting reliability (CRLB) and spatial variations within ROIs (SpaVar) is improved using SSP. When 5 to 6 components were used in SSP and PG+SSP, the metabolite concentrations and the associated SpaVar and CRLB are at the same level as those from the OVS. CONCLUSION: We have demonstrated that the SSP method can be used to suppress the lipid signals of MRSI and SSP with 5 to 6 components is suggested to have a similar suppression performance as the OVS method. PMID- 30277270 TI - Machine learning improves classification of preclinical models of pancreatic cancer with chemical exchange saturation transfer MRI. AB - PURPOSE: We sought to assess whether machine learning-based classification approaches can improve the classification of pancreatic tumor models relative to more simplistic analysis methods, using T1 relaxation, CEST, and DCE MRI. METHODS: The T1 relaxation time constants, % CEST at five saturation frequencies, and vascular permeability constants from DCE MRI were measured from Hs 766 T, MIA PaCa-2, and SU.86.86 pancreatic tumor models. We used each of these measurements as predictors for machine learning classifier algorithms. We also used principal component analysis to reduce the dimensionality of entire CEST spectra and DCE signal evolutions, which were then analyzed using classification methods. RESULTS: The T1 relaxation time constants, % CEST amplitudes at specific saturation frequencies, and the relative Ktrans and kep values from DCE MRI could not classify all three tumor types. However, the area under the curve from DCE signal evolutions could classify each tumor type. Principal component analysis was used to analyze the entire CEST spectrum and DCE signal evolutions, which predicted the correct tumor model with 87.5% and 85.1% accuracy, respectively. CONCLUSIONS: Machine learning applied to the entire CEST spectrum improved the classification of the three tumor models, relative to classifications that used % CEST values at single saturation frequencies. A similar improvement was not attained with machine learning applied to T1 relaxation times or DCE signal evolutions, relative to more simplistic analysis methods. PMID- 30277272 TI - Functional tractography of white matter by high angular resolution functional correlation imaging (HARFI). AB - PURPOSE: Functional magnetic resonance imaging with BOLD contrast is widely used for detecting brain activity in the cortex. Recently, several studies have described anisotropic correlations of resting-state BOLD signals between voxels in white matter (WM). These local WM correlations have been modeled as functional correlation tensors, are largely consistent with underlying WM fiber orientations derived from diffusion MRI, and appear to change during functional activity. However, functional-correlation tensors have several limitations. The use of only nearest-neighbor voxels makes functional-correlation tensors sensitive to noise. Furthermore, adjacent voxels tend to have higher correlations than diagonal voxels, resulting in orientation-related biases. Finally, the tensor model restricts functional correlations to an ellipsoidal bipolar-symmetric shape, and precludes the ability to detect complex functional orientation distributions (FODs). METHODS: We introduce high-angular-resolution functional-correlation imaging (HARFI) to address these limitations. In the same way that high-angular resolution diffusion imaging (HARDI) techniques provide more information than diffusion tensors, we show that the HARFI model is capable of characterizing complex FODs expected to be present in WM. RESULTS: We demonstrate that the unique radial and angular sampling strategy eliminates orientation biases present in tensor models. We further show that HARFI FODs are able to reconstruct known WM pathways. Finally, we show that HARFI allows asymmetric "bending" and "fanning" distributions, and propose asymmetric and functional indices which may increase fiber tracking specificity, or highlight boundaries between functional regions. CONCLUSIONS: The results suggest the HARFI model could be a robust, new way to evaluate anisotropic BOLD signal changes in WM. PMID- 30277273 TI - Integrated radio-frequency/wireless coil design for simultaneous MR image acquisition and wireless communication. AB - PURPOSE: An innovative radio-frequency (RF) coil design that allows RF currents both at the Larmor frequency and in a wireless communication band to flow on the same coil is proposed to enable simultaneous MRI signal reception and wireless data transfer, thereby minimizing the number of wired connections in the scanner without requiring any modifications or additional hardware within the scanner bore. METHODS: As a first application, the proposed integrated RF/wireless coil design was further combined with an integrated RF/shim coil design to perform not only MR image acquisition and wireless data transfer, but also localized B0 shimming with a single coil. Proof-of-concept phantom experiments were conducted with such a coil to demonstrate its ability to simultaneously perform these three functions, while maintaining the RF performance, wireless data integrity, and B0 shimming performance. RESULTS: Performing wirelessly controlled shimming of localized B0 inhomogeneities with the coil substantially reduced the B0 root-mean square error (>70%) and geometric distortions in echo-planar images without degrading the image quality, signal-to-noise ratio (<1.7%), or wireless data throughput (maximum variance = 0.04 Mbps) of the coil. CONCLUSIONS: The RF/wireless coil design can provide a solution for wireless data transfer that can be easily integrated into existing MRI scanners for a variety of applications. PMID- 30277274 TI - 3D high-resolution imaging of 2-hydroxyglutarate in glioma patients using DRAG EPSI at 3T in vivo. AB - PURPOSE: To develop 3D high-resolution imaging of 2-hydroxyglutarate (2HG) at 3T in vivo. METHODS: Echo-planar spectroscopic imaging with dual-readout alternated gradients (DRAG-EPSI), which was recently reported for 2D imaging of 2HG at 7T, was tested for 3D imaging of 2HG at 3T. The frequency drifts and acoustic noise induced by DRAG-EPSI were investigated in comparison with conventional EPSI. Four patients with IDH-mutant gliomas were enrolled for 3D imaging of 2HG and other metabolites. A previously reported 2HG-tailored TE 97-ms PRESS sequence preceded the DRAG-EPSI readout gradients. Unsuppressed water, acquired with EPSI, was used as reference for multi-channel combination, eddy-current compensation, and metabolite quantification. Spectral fitting was conducted with the LCModel using in-house basis sets. RESULTS: With gradient strength of 4 mT/m and slew rate of 20 mT/m/ms, DRAG-EPSI produced frequency drifts smaller by 5.5-fold and acoustic noise lower by 25 dB compared to conventional EPSI. In a 19-min scan, 3D DRAG EPSI provided images of 2HG with precision (CRLB <10%) at a resolution of 10 * 10 * 10 mm3 for a field of view of 240 * 180 * 80 mm3. 2HG was estimated to be 5 mM in a pre-treatment patient. In 3 post-surgery patients, 2HG estimates were 3-6 mM, and the 2HG distribution was different from the water-T2 image pattern or highly concentrated in the post-contrast enhancing region. CONCLUSION: Together with 2HG-optimized PRESS, DRAG-EPSI provides an effective tool for reliable 3D high-resolution imaging of 2HG at 3T in vivo. PMID- 30277275 TI - Transcutaneous oxygen measurement in humans using a paramagnetic skin adhesive film. AB - PURPOSE: Transcutaneous oxygen tension (TcpO2 ) provides information about blood perfusion in the tissue immediately below the skin. These data are valuable in assessing wound healing problems, diagnosing peripheral vascular/arterial insufficiency, and predicting disease progression or the response to therapy. Currently, TcpO2 is primarily measured using electrochemical skin sensors, which consume oxygen and are prone to calibration errors. The goal of the present study was to develop a reliable method for TcpO2 measurement in human subjects. METHODS: We have developed a novel TcpO2 oximetry method based on electron paramagnetic resonance (EPR) principles with an oxygen-sensing skin adhesive film, named the superficial perfusion oxygen tension (SPOT) chip. The SPOT chip is a 3-mm diameter, 60-MUm thick circular film composed of a stable paramagnetic oxygen sensor. The chip is covered with an oxygen-barrier material on one side and secured on the skin by a medical adhesive transfer tape to ensure that only the oxygen that diffuses through the skin surface is measured. The method quantifies TcpO2 through the linewidth of the EPR spectrum. RESULTS: Repeated measurements using a cohort of 10 healthy human subjects showed that the TcpO2 measurements were robust, reliable, and reproducible. The TcpO2 values ranged from 7.8 +/- 0.8 to 22.0 +/- 1.0 mmHg in the volar forearm skin (N = 29) and 8.1 +/- 0.3 to 23.4 +/- 1.3 mmHg in the foot (N = 86). CONCLUSIONS: The results demonstrated that the SPOT chip can measure TcpO2 reliably and repeatedly under ambient conditions. The SPOT chip method could potentially be used to monitor TcpO2 in the clinic.

AB - PURPOSE: Uneven flow distribution in patients with Fontan circulation is suspected to lead to complications. 4D flow MRI offers evaluation using time resolved pathlines; however, the potential error is not well understood. The aim of this study was to systematically assess variability in flow distribution caused by well-known sources of error. METHODS: 4D flow MRI was acquired in 14 patients with Fontan circulation. Flow distribution was quantified by the % of caval venous flow pathlines reaching the left and right pulmonary arteries. Impact of data acquisition and data processing uncertainties were investigated by (1) probabilistic 4D blood flow tracking at varying noise levels, (2) down sampling to mimic acquisition at different spatial resolutions, (3) pathline calculation with and without eddy current correction, and (4) varied segmentation of the Fontan geometry to mimic analysis errors. RESULTS: Averaged among the cohort, uncertainties accounted for flow distribution errors from noise <=3.2%, low spatial resolution <=2.3% to 3.8%, eddy currents <=6.4%, and inaccurate segmentation <=3.9% to 9.1% (dilation and erosion, respectively). In a worst-case scenario (maximum additive errors for all 4 sources), flow distribution errors were as high as 22.5%. CONCLUSION: Inaccuracies related to postprocessing (segmentation, eddy currents) resulted in the largest potential error (<=15.5% combined) whereas errors related to data acquisition (noise, low spatial resolution) had a lower impact (<=5.5%-7.0% combined). Whereas it is unlikely that these errors will be additive or affect the identification of severe asymmetry, these results illustrate the importance of eddy current correction and accurate segmentation to minimize Fontan flow distribution errors. PMID- 30277277 TI - Monitoring daily routine performance in quantitative NMR (qNMR) spectroscopy: Is the system suitability test necessary? AB - Nuclear magnetic resonance spectrometry (NMR) finds numerous applications in pharmacy, cosmetic, and food control as well as in developing tools for "big data" analysis. However, there remains a need for automated tools to assess instrument system suitability in real time for each particular routine sample. An automated procedure has been introduced to monitor a number of characteristics (resolution, symmetry, and half width) in real time after the measurement of two samples distributed by the vendor (0.3% CHCl3 in acetone-d6 with tetramethylsilane and 2 mM sucrose in H2 O-D2 O). The results over 11 months were discussed in terms of average values, standard deviations, and spectrometer variability. Moreover, multivariate statistical procedure was implemented to evaluate metrics generated from three NMR spectrometers. Performance of three NMR spectrometers (500 MHz with BBO Prodigy Cryoprobe, 500 MHz with BBFOPLUS SmartProbe, and 600 MHz with BBO Cryoprobe) differed significantly. The developed routine was also applied to calculate the performance characteristics during routine quantitative NMR experiments. The procedure was evaluated for NMR spectra of 659 active pharmaceutical ingredients dissolved in CDCl3 , DMSO, and CH3 OD. This test is more preferable than the routine procedure using standard solutions because the performance is estimated separately for each matrix at the specific time point of measurements. Our automated routine is the ideal tool for any NMR laboratory. In full automation, the NMR data are validated directly for each sample, making unnecessary daily measurements of standard solutions and manual evaluation to their NMR spectra. PMID- 30277278 TI - Temporal availability of public health care in developing countries of the Caribbean: An improved two-step floating catchment area method for estimating spatial accessibility to health care. AB - Due to restrictions on personnel availability, the service capacity at a health facility may vary day to day based on an established schedule. This temporal variability influences a user's choice set, modifying their possible choices. As a result, the spatial accessibility of public health care may be constantly reshaped rather than being a relatively static experience as commonly represented in place-based spatial accessibility literature. Building on the latest advances in the two-step floating catchment method, this study presents further advancements through the inclusion of health facility schedules to better represent health care availability in the assessment of accessibility. The results show that the proposed method reveals communities with relatively poor accessibility that are hidden with many existing methods. By exposing the available care within time windows, a more accurate picture of the services available to be accessed is revealed. The findings suggest that improvement in the number of doctor hours at health facilities may reduce the disparities found in accessibility scores for communities. Further, in public health care systems similarly structured, the spatial configuration of facilities with doctors can be considered at the administrative level to ensure adequate levels of access across the jurisdiction. PMID- 30277279 TI - How many beds? Capacity implications of hospital care demand projections in the Irish hospital system, 2015-2030. AB - Existing Irish hospital bed capacity is low by international standards while Ireland also reports the highest inpatient bed occupancy rate across OECD countries. Moreover, strong projected population growth and ageing is expected to increase demand for hospital care substantially by 2030. Reform proposals have suggested that increased investment and access to nonacute care may mitigate some increased demand for hospital care over the next number of years, and it is in this context that the Irish government has committed to increase the supply of public hospital beds by 2600 by 2027. Incorporating assumptions on the rebalancing of care to nonhospital settings, this paper analyses the capacity implications of projected demand for hospital care in Ireland to 2030. This analysis employs the HIPPOCRATES macrosimulation projection model of health care demand and expenditure developed in the ESRI to project public and private hospital bed capacity requirements in Ireland to 2030. We examine 6 alternative projection scenarios that vary assumptions related to population growth and ageing, healthy ageing, unmet demand, hospital occupancy, hospital length of stay, and avoidable hospitalisations. We project an increased need for between 4000 and 6300 beds across public and private hospitals (an increase of between 26.1% and 41.1%), of which 3200 to 5600 will be required in public hospitals. These findings suggest that government plans to increase public hospital capacity over the 10 years to 2027 by 2600 may not be sufficient to meet demand requirements to 2030, even when models of care changes are accounted for.

PMID- 30277280 TI - A Biomimetic Supramolecular Approach for Charge Transfer between Donor and Acceptor Chromophores with Aggregation-Induced Emission. AB - Supramolecular assembly of chromophores with inherent resistance to aggregation induced self-quenching is significant to applications such as chemical sensing and organic light emitting diodes (OLEDs). In this work, molecular gels with aggregation-induced emission (AIE) are constructed by simply coassembling AIE chromophores (electron donor or acceptor) with a nonfluorescent molecular gelator. The binary gels are fluorescent even at very low concentrations of the AIE chromophores, indicating that the rotation of their aromatic cores is restricted in the gel network. In tertiary gels, the fluorescence of the donor chromophore can be efficiently reduced by the acceptor chromophore through a combination of static and dynamic quenching process, via charge transfer from the donor to the acceptor. This work demonstrates a convenient approach to fabricate a supramolecular charge transfer system using an AIE donor and acceptor.

AB - Microbiota alterations are observed in pathological conditions, and their regulation is a subject of great interest. Gut microbes are affected by diet, and plant polyphenols may have positive effect on gut microbiota; however, plant derived extracts may have toxic effects. Guarana (Paullinia cupana Mart.) is a nontraditional medicinal plant applied worldwide. Guarana yields an alkaloid and polyphenol-rich seed with antimicrobial, antioxidant, and anti-inflammatory properties, where caffeine is the major compound. We evaluated the effects of guarana seed powder (GSP) and purified caffeine on gut microbial composition and redox and inflammatory parameters in Wistar rats after 21 days of treatment. Fecal microbiota was analyzed utilizing 16S rDNA sequencing. Antioxidant enzymes activities from liver, kidney, and colon, as well as oxidative damage markers, were evaluated. Total nonenzymatic antioxidant potential was also evaluated. Microbiota was altered by both treatments, GSP and caffeine, without loss of diversity. In the liver, the kidney, and the colon, we observed a decrease in the antioxidant enzymes activities in the GSP group with no increase in the expression of oxidative damage markers, although some enzymes were also regulated by caffeine. Taken together, these results suggested that GSP ameliorates redox parameters but negatively affected gut microbiota, partially via caffeine. PMID- 30277283 TI - A Dynamically Stabilized Single-Nickel Electrocatalyst for Selective Reduction of Oxygen to Hydrogen Peroxide. AB - On-location electrochemical generation of H2 O2 is of great current interest. Herein, selective two-electron reduction of O2 to H2 O2 by a single [NiII (H2 O)6 ]2+ cation that is dynamically associated with a negatively charged metal-organic layer (MOL) by hydrogen bonding and coulombic interactions is reported. In contrast, NiII centers covalently immobilized on the MOL reduce O2 to H2 O in a four- electron process. Oxygen adsorption by [NiII (H2 O)6 ]2+ followed by two electron reduction generates neutral [NiII (H2 O)4 (OH)(OOH)]0 , which momentarily disconnects from the negatively charged MOL to avoid the injection of additional electrons. Release of H2 O2 from [NiII (H2 O)4 (OH)(OOH)]0 regenerates [NiII (H2 O)6 ]2+ , which regains affinity to the MOL. Such dynamically associated NiII single-metal electrocatalysts ensure high selectivity and represent a new strategy for generating selective catalysts for electrochemical production of important chemicals. PMID- 30277284 TI - Ginsenoside Rg3 and Rh2 protect trimethyltin-induced neurotoxicity via prevention on neuronal apoptosis and neuroinflammation. AB - The acute exposure of trimethyltin (TMT) develops clinical syndrome characterized by amnesia, aggressive behavior, and complex seizures. This neurotoxicant selectively induces hippocampal neuronal injury and glial activation accompanied with resultant neuroinflammation. Here we report two candidates ginsenosides Rg3 and Rh2 as neuroprotection agents using a mouse model of TMT intoxication via a single injection (2 mg/kg) and primary neuronal culture systems. Four-week administration of Rg3 or Rh2 significantly reduced TMT-induced seizures and behavioral changes. Rg3 and Rh2 significantly attenuated the oxidative stress evidenced by improvement on antioxidant enzymes and neuronal loss and astrocytic activation in mouse brain. In primary cultures, TMT induced significant neuronal death after 24-h intoxication and vigorous secretion of inflammatory cytokines (IL-1alpha/beta, IL-6, TNF-alpha, and MCP-1) in astrocytes. Pretreatment with Rg3 or Rh2 not only reduced cell death but efficiently suppressed above mentioned inflammatory cytokines confirmed by antibody array test. The underlying protective mechanism by Rg3 and Rh2 was delineated through selective upregulation of PI3K/Akt and suppression of ERK activation. Intriguingly, Rg3 and Rh2 protected oligodendrocyte progenitor cells (O-2A) from TMT intoxication via promoting type 2 astrocytic differentiation without further inflammatory activation. Collectively, Rg3 and Rh2 interventions aimed at reducing oxidative stress and neuroinflammation neurotoxicity therefore are of therapeutic benefit in TMT-induced neurodegeneration. PMID- 30277285 TI - A Versatile New Paradigm for the Design of Optical Nanosensors Based on Enzyme Mediated Detachment of Labeled Reporters: The Example of Urea Detection. AB - Here, a new bio-inspired nanoarchitectonics approach for the design of optical probes is presented. It is based on nanodevices that combine 1) an enzymatic receptor subunit, 2) a signaling subunit (consisting of a labeled reporter attached to a silica surface), and 3) a mechanism of communication between the two sites based on the production of chemical messengers by the enzymatic subunit, which induces the detachment of the reporter molecules from the silica surface. As a proof of concept, a urea nanosensor based on the release of Alexa Fluor-647-labeled oligonucleotide from enzyme-functionalized Janus gold mesoporous-silica nanoparticles (Au-MSNPs) was developed. The Janus particles were functionalized on the silica face with amino groups to which the labeled oligonucleotides were attached by electrostatic interactions, whereas the gold face was used for grafting urease enzymes. The nanodevice was able to release the fluorescent oligonucleotide through the enzyme-mediated hydrolysis of urea to ammonia and the subsequent deprotonation of amino groups on the silica face. This simple nanodevice was applied for the fluorometric detection of urea in real human blood samples and for the identification of adulterated milk. Given the large variety of enzymes and reporter species that could be combined, this is a general new paradigm that could be applied to the design of a number of optical probes for the detection of target analytes. PMID- 30277286 TI - Three-Stage Aromaticity Switching in Boron(III) and Phosphorus(V) N-Fused p Benziporphyrin. AB - Insertion of PCl3 or PhBCl2 into 5,10,15,20-tetraaryl-p-benziporphyrin prompted an intramolecular fusion affording anti-aromatic phosphorus(V) and non-aromatic boron(III) complexes of two N-fused dihydro-p-benziporphyrin isomers. These macrocycles are classified as carbatriphyrin due to the common [CNN] coordination. A sequence of direct transformations, triggered by protonation or two-electron redox processes, afforded a set of three mutually convertible N fused p-benziporphyrinoids, with distinct anti-aromatic, non-aromatic, and aromatic spectroscopic features. PMID- 30277287 TI - Histopathological impairment of common carp (Cyprinus carpio) induced through povidone-iodine exposure. AB - Histological biomarkers are one of the most advantageous tools in monitoring toxicological studies under experimental condition in laboratory. Since disinfectants are extensively inflowing into aquatic ecosystems, this study conducted on common carp to examine the effect of betadine solution on the liver and gill tissue. A 120-carp were kept for 2 weeks in the 100-l aquarium Different concentrations of povidone-iodine (betadine) prepared in three replications and a control group was prepared with no betadine (0, 5, 7, 8, and 9 ppm). Most lesions observed at gill tissue include adhesion secondary lamella, bleeding, destruction of secondary lamellae, hyperplasia secondary blades, curvature second blade, destroying the primary lamellae. Whats more, most lesions observed in liver tissue include bleeding, ascites liver, destruction of liver cells, bile stagnation. Betadine solution, could cause damage to the liver and gills tissues, although gill lesions were more evident than liver. Also increase of concentration led to elevation at lesions of both organs. Overally, the results revealed that using povidon-iodine as a disinfectant materials and entering into rivers and aquatic ecosystems could have undesirable effects and even death of this fish. Disinfectants, either in low or high concentration, could be very lethal for fish. However the defects seen in this study also could affect osmoregulation and metabolism as two main functions of gill and liver. PMID- 30277288 TI - Spatial configuration processing in visual word form perception and reading abilities in Chinese. AB - The analysis of spatial relations among components of a character is important in identifying visual word forms. We investigated such spatial configuration processing for Chinese characters in dyslexic children (aged 9-12 years) and two groups of typically developing children, matched according to chronological age or reading level. In this study, we used real characters and noncharacters to manipulate the spatial configuration between character components while preserving their local features. Both characters were displayed either in an upright or inverted position. Participants were asked to quickly determine whether the two presented stimuli were identical. A significant interaction between character type and character orientation showed children's matching performance was better in upright real characters than in the inverted version, but such effect was absent in noncharacters. This indicated that regardless of reading skills, children developed the ability to use local configuration information to visually identify words. Dyslexic children performed poorly in both real-character and noncharacter conditions. Furthermore, compared with control groups, dyslexic children performed worse in real-character conditions, which were close to the noncharacter performance of other groups. This reflected an impairment of global visual word-form processing (i.e., spatial configuration between components) in dyslexia. PMID- 30277289 TI - High recovery rate of consciousness by high-volume filtrate hemodiafiltration for fulminant hepatitis. AB - AIM: An artificial liver support (ALS) system sustaining patients with acute liver failure (ALF) in good condition until recovery of the native liver or performance of liver transplantation (LT), is essential for the improvement of the poor prognosis of ALF despite the lack of survival benefit. We aimed to investigate the efficacy of various ALS systems for fulminant hepatitis (FH) carried out in our liver unit so far, focusing on the restoration of consciousness from hepatic encephalopathy. METHODS: One hundred and ten consecutive adult Japanese patients with FH admitted to Chiba University Hospital (Chiba, Japan) between 1988 and 2016 who received ALS were analyzed. RESULTS: Recovery rate of consciousness improved with the increased dialysate flow rate and filtrate rate: 37.5% by plasma exchange (PE), 51.9% by PE + continuous hemodiafiltration (CHDF), 57.7% by slow PE (sPE) + high-flow CHDF (HFCHDF) (QD = 300 mL/min), 88.6% by HFCHDF (QD = 500 mL/min) (+ sPE), and 92.9% by on-line HDF (OLHDF) (+ sPE). All patients except one, who could not be fully treated because of circulatory failure, recovered consciousness by OLHDF, including those whose liver function were completely abolished. Superiority of HFCHDF (QD = 500 mL/min) and OLHDF was also shown in patients who died without LT or received LT. CONCLUSIONS: More effective ALS should be recognized considering the extremely high recovery rate of consciousness. In particular, OLHDF with predilution reduces the cost of substitution fluid by supplying an unlimited amount of dialysate as substitution fluid prepared using an on-line system, and simplifies the procedure for the management. PMID- 30277290 TI - Adult-related haematopoietic stem cell donor experiences and the provision of information and psychosocial support: A systematic literature review. AB - For blood cancer patients, haematopoietic stem cells (HSC) donated by a relative can be lifesaving. However, related donors can face significant physical and psychosocial challenges. As the demand for adult-related HSC donors is increasing, it is important to review our understanding of adult-related HSC donors' need for and availability of information and psychosocial support with a view to identifying gaps in the literature. A systematic review of relevant studies (2000-2017) was conducted using five databases with supplementary hand searching. Sixteen studies involving 1,024 related HSC donors met the following criteria: English or Dutch language, peer-reviewed, sampled first-time-related HSC donors, >=18 years, haematological malignancies, assessed psychosocial aspects, retrospective or prospective and with or without comparison group. Data were abstracted, and study quality was assessed using the PRISMA criteria. Studies contained limited information on the provision of information and psychosocial support. Most studies addressed pre-donation information, and none reported providing information or support to donors post-donation. Additionally, few studies formally assessed unmet needs. Recommendations include improved transparency of reporting for the availability, sources and timing of information and psychosocial support, and the identification of unmet needs to enable the development of educational and psychosocial interventions for this invaluable donor population. PMID- 30277291 TI - Protocol identification and preservation of myxozoan parasites for microscopy with silver nitrate (Klein's dry) staining technique. AB - : The present study, discusses a first report of staining techniques with silver nitrate (AgNO3 ) stain for the preservation and identification of myxozoans globally. The silver nitrate stain was used to prepare permanent slide preparation of myxozoans with some adaptations made in our laboratory. Fresh air dried smear were stained with silver nitrate stain ensuing dark brown color polar capsules and light brown color of spore-wall. The stain is everlasting for years differing to other stains like Geimsa, iron-heamotoxylin Zeihl-Neelsen Blue, and trichome stains. RESEARCH HIGHLIGHTS: Stains usually fade with time and fail to disclose the morphological characters of the specimen. Present staining method helps to detect less infection in the tissue locating the myxospores. The Klein dry method (1958) is useful and suitable for long term preservation of the myxozoan slides and morphological description.

AB - Terpenoids have diverse structures and thus represent an important class of biologically active natural products. The structural diversity of terpenoids originates from the coupling of prenyl diphosphate substrates, such as isopentenyl diphosphate and dimethylallyl diphosphate. These isoprenyl diphosphates undergo canonical and sequential "head-to-tail" coupling catalyzed by terpene synthases, followed by modifications such as cyclization, hydroxylation, and glycosylation. In recent years, several terpene synthases that catalyze irregular "non-head-to-tail" couplings to afford branched terpenoids have been identified. This minireview describes structural and mechanistic insights into these unusual coupling reactions that provide a new strategy for the structural diversification of natural products. PMID- 30277293 TI - Lung cancer in Spanish women: The WORLD07 project. AB - The WORLD07 study was a female-specific database, to prospectively characterise the clinical, histological, molecular and treatment-related features in Spanish women with lung cancer. Data were collected from patients' medical records and patient interviews from October 2007 to December 2012. A total of 2,060 women were analysed: median age, 61.3 years; white, 98.6%; postmenopausal, 80.2%; and no smokers, 55% including never smokers and ex-smokers. A family history of cancer was found in 42.5% of patients, 12.0% of patients had had a previous history of cancer (breast cancer, 39.7%). Most patients (85.8%) were diagnosed of non-small-cell lung cancer (NSCLC), most commonly reported with adenocarcinoma (71.4%), which was stage IV at diagnosis in 57.6%. Median overall survival (OS) for the entire population was 24.0 months, with a 1- and 2-year survival rate of 70.7% and 50.0% respectively. Median OS in patients with small-cell lung cancer was 18.8 months versus 25.0 months in patients with NSCLC (p = 0.011). Lung cancer appears to be a biologically different disease in women. By collecting prospective information about characteristics of women with lung cancer attending university hospitals in Spain, we hope to highlight the need to develop strategies based on gender differences and influence future healthcare policy.

PMID- 30277295 TI - No-touch ablation in hepatocellular carcinoma has the potential to prevent intrasubsegmental recurrence to the same degree as surgical resection. AB - AIM: The aim of this study was to clarify the utility of a no-touch pincer ablation procedure that uses bipolar electrodes to prevent intrasubsegmental tumor recurrence after radiofrequency ablation (RFA) for patients with hepatocellular carcinoma (HCC) compared to surgical resection. METHODS: We evaluated 175 consecutive patients with HCC (single nodule, tumor diameter <= 30 mm) who underwent surgical resection (146 received partial resection) and 313 patients who received RFA; 277 patients received touch ablation using a monopolar or bipolar RFA device, and 36 received no-touch ablation using a bipolar RFA device. Pretreatment arterial and portal phase dynamic computed tomography (CT) or magnetic resonance imaging (MRI) images were classified into four enhancement patterns: Type 1 and Type 2 are homogeneous enhancement patterns without or with increased arterial blood flow, respectively; Type 3 is a heterogeneous enhancement pattern with a septum-like structure; and Type 4 is an irregularly shaped ring structure enhancement pattern. RESULTS: Cumulative recurrence rates significantly differed between procedures (surgical resection, 7.5%; no-touch ablation, 2.9%; and touch ablation, 17.7% at the third year; P = 0.005). Multivariate Cox proportional hazards analysis revealed that enhancement pattern type (Type 3: hazard ratio [HR], 2.95; P = 0.002; and Type 4: HR, 3.88, P = 0.002), treatment procedure (touch ablation: HR, 3.36; P < 0.001), and serum alpha-fetoprotein level (>=30 MUg/L: HR, 1.87; P = 0.009) were significant predictors of intrasubsegmental recurrence. No significant differences between no touch ablation and surgical resection were observed. CONCLUSION: The no-touch pincer ablation procedure has the potential to prevent intrasubsegmental recurrence after RFA for patients with HCC to the same degree as partial resection. PMID- 30277296 TI - Visible-Light-Induced Pyridylation of Remote C(sp3 )-H Bonds by Radical Translocation of N-Alkoxypyridinium Salts. AB - Metal-free, visible-light-induced site-selective heteroarylation of remote C(sp3 )-H bonds has been accomplished through the design of N-alkoxyheteroarenium salts serving as both alkoxy radical precursors and heteroaryl sources. The transient alkoxy radical can be generated by the single-electron reduction of an N alkoxypyridinium substrate by a photoexcited quinolinone catalyst. Subsequent radical translocation of the alkoxy radical forms a nucleophilic alkyl radical intermediate, which undergoes addition to the substrate to achieve remote C(sp3 ) H heteroarylation. This cascade strategy provides a powerful platform for remote C(sp3 )-H heteroarylation in a controllable and selective manner and is well suited for late-stage functionalization of complex bioactive molecules. PMID- 30277297 TI - Exploring comorbid depression and physical health trajectories: A case-based computational modelling approach. AB - While comorbid depression/physical health is a major clinical concern, the conventional methods of medicine make it difficult to model the complexities of this relationship. Such challenges include cataloguing multiple trends, developing multiple complex aetiological explanations, and modelling the collective large-scale dynamics of these trends. Using a case-based complexity approach, this study engaged in a richly described case study to demonstrate the utility of computational modelling for primary care research. N = 259 people were subsampled from the Diamond database, one of the largest primary care depression cohort studies worldwide. A global measure of depressive symptoms (PHQ-9) and physical health (PCS-12) were assessed at 3, 6, 9, and 12 months and then annually for a total of 7 years. Eleven trajectories and 2 large-scale collective dynamics were identified, revealing that while depression is comorbid with poor physical health, chronic illness is often low dynamic and not always linked to depression. Also, some of the cases in the unhealthy and oscillator trends remain ill without much chance of improvement. Finally, childhood abuse, partner violence, and negative life events are greater amongst unhealthy trends. Computational modelling offers a major advance for health researchers to account for the diversity of primary care patients and for developing better prognostic models for team-based interdisciplinary care.

PMID- 30277299 TI - High single-cell diversity in carbon and nitrogen assimilations by a chain forming diatom across a century. AB - Almost a century ago Redfield discovered a relatively constant ratio between carbon, nitrogen and phosphorus in particulate organic matter and nitrogen and phosphorus of dissolved nutrients in seawater. Since then, the riverine export of nitrogen to the ocean has increased 20 fold. High abundance of resting stages in sediment layers dated more than a century back indicate that the common planktonic diatom Skeletonema marinoi has endured this eutrophication. We germinated unique genotypes from resting stages originating from isotope-dated sediment layers (15 and 80 years old) in a eutrophied fjord. Using secondary ion mass spectrometry (SIMS) combined with stable isotopic tracers, we show that the cell-specific carbon and nitrogen assimilation rates vary by an order of magnitude on a single-cell level but are significantly correlated during the exponential growth phase, resulting in constant assimilation quota in cells with identical genotypes. The assimilation quota varies largely between different clones independent of age. We hypothesize that the success of S. marinoi in coastal waters may be explained by its high diversity of nutrient demand not only at a clone-specific level but also at the single-cell level, whereby the population can sustain and adapt to dynamic nutrient conditions in the environment.

An Australian perspective. AB - BACKGROUND: While most colorectal cancer (CRC) recurrences reportedly occur within 3 years following curative treatment, many studies are limited by short term follow-up. This study examines the time to recurrence of CRC in a large Australian cohort with a long follow-up period and assesses whether time to recurrence has changed over time. METHODS: A comprehensive prospective database of patients undergoing resection for CRC is maintained at Concord Hospital, Sydney. Demographic and time to recurrence data were extracted for patients who developed a recurrence following potentially curative resection for colon cancer from 1995 to 2010 and rectal cancer from 1971 to 2010. Non-deceased patients had a minimum of 5 years follow-up. RESULTS: Between 1995 and 2010, 2575 patients with CRC underwent surgery. After exclusions, 386 had recurrence following potentially curative resection, ranging from 1 to 172.5 months (median 20.3) after treatment. Within 1 year, 27.5% recurred, 57.5% by 2 years, 74.6% by 3 years, 85.5% by 4 years and 89.6% by 5 years. There was no difference in time to recurrence between colon and rectal cancers (P = 0.674). Among patients having a potentially curative resection for rectal cancer between 1971 and 2010, 386 recurred. There was no difference in time to recurrence by decade (P = 0.863). CONCLUSION: The majority of recurrences occurred within 3 years of curative treatment. Had surveillance been limited to 5 years, detection of more than 10% of recurrences would have been delayed. Time to recurrence for rectal cancer has not changed in over 40 years, despite treatment advances.

AB - BACKGROUND: The treatment of choice for early stage non-small cell lung cancer (NSCLC) is surgical resection. Little is known about the short- and long-term outcomes among very elderly patients. We sought to determine predictors of short- and long-term survival among octogenarians undergoing curative-intent resection for NSCLC in Victoria, Australia. METHODS: We retrospectively reviewed data from all patients aged >=80 years who underwent curative-intent resection for NSCLC over 12 years (January 2005-December 2016) across five tertiary centres. We examined effect of age, stage of disease, extent of surgery and lung function on short- and long-term survival. RESULTS: Two hundred patients aged >=80 years underwent curative-intent resections. Mortality at 30 and 120 days was 2.9% and 5.9%, respectively. Increased early mortality was observed among those >=83 years, at 30 days (6.8% versus 0.8%, P = 0.044) and 120 days (12.2% versus 2.3%, P = 0.0096). Early mortality was highest among patients >=83 years requiring lobectomy, compared to sub-lobar resection at 120 days (17% versus 3.8%, P = 0.019). Long-term survival was predicted by age and stage of disease. Among patients with Stage I disease aged <83 years, lobectomy was associated with superior 5-year survival, compared to sub-lobar resection (83% versus 61%, P = 0.02). CONCLUSION: In carefully selected elderly patients undergoing curative intent resection of early stage NSCLC, both short- and long-term outcomes appear consistent with younger historical cohorts. Early mortality was associated with lobectomy in those with advanced age. Older patients undergoing lobectomy appeared to be at highest risk for early mortality, while younger patients with Stage I disease undergoing at least lobectomy appear to have the best long-term survival. PMID- 30277304 TI - Solid-Phase Conversion of Four Stereoisomers into a Single Enantiomer. AB - Viedma ripening is an emerging method for the solid-phase deracemization of mixtures of enantiomers. Up to now, the scope of the method has remained limited to molecules with a single stereocenter. We show here that this method can be extended to obtain a single enantiomer from a mixture of stereoisomers with two different stereocenters. In addition, we show that by using tailor-made chiral additives, the conversion time can be reduced by a factor of 100.

AB - The assimilation of inorganic compounds in foraminiferal metabolism compared to predation or organic matter assimilation is unknown. Here, we investigate possible inorganic-compound assimilation in Nonionellina labradorica, a common kleptoplastidic benthic foraminifer from Arctic and North Atlantic sublittoral regions. The objectives were to identify the source of the foraminiferal kleptoplasts, assess their photosynthetic functionality in light and darkness and investigate inorganic nitrogen and sulfate assimilation. We used DNA barcoding of a ~ 830 bp fragment from the SSU rDNA to identify the kleptoplasts and correlated transmission electron microscopy and nanometre-scale secondary ion mass spectrometry (TEM-NanoSIMS) isotopic imaging to study 13 C-bicarbonate, 15 N ammonium and 34 S-sulfate uptake. In addition, respiration rate measurements were determined to assess the response of N. labradorica to light. The DNA sequences established that over 80% of the kleptoplasts belonged to Thalassiosira (with 96% 99% identity), a cosmopolitan planktonic diatom. TEM-NanoSIMS imaging revealed degraded cytoplasm and an absence of 13 C assimilation in foraminifera exposed to light. Oxygen measurements showed higher respiration rates under light than dark conditions, and no O2 production was detected. These results indicate that the photosynthetic pathways in N. labradorica are not functional. Furthermore, N. labradorica assimilated both 15 N-ammonium and 34 S-sulfate into its cytoplasm, which suggests that foraminifera might have several ammonium or sulfate assimilation pathways, involving either the kleptoplasts or bona fide foraminiferal pathway(s) not yet identified. PMID- 30277306 TI - Exosomes from human placenta purified by affinity chromatography on sepharose bearing immobilized antibodies against CD81 tetraspanin contain many peptides and small proteins. AB - Exosomes are nanovesicles (40-100 nm) containing various RNAs and different proteins. Exosomes are involved in intracellular communication and immune system function. Exosomes from different sources are usually isolated using standard methods-centrifugation and ultracentrifugations. Exosomes isolated by these procedures were reported to contain from a few dozen to thousands of different proteins. Here crude vesicle preparations from five placentas (normal pregnancy) were first obtained using standard centrifugation procedures. According to electron-microscopic studies, these preparations contained vesicles of different size (30-225 nm), particles of round shape of average electron density ("nonvesicles" 20-40 nm) (A), structured clusters of associated proteins and shapeless aggregations (B), as well as ring-shaped 10-14 nm structures formed by ferritin (C). After additional purification of the vesicle preparations by gel filtration on Sepharose 4B, the main part of protein structures was removed; however, the preparations still contained small admixtures of components A-C. Further purification of the preparations by affinity chromatography on Sepharose bearing immobilized antibodies against exosome surface protein CD81 led to isolation of highly purified exosomes (40-100 nm). These exosomes according to electron microscopy data contained tetraspanin embedded in the membrane, which was stained with antibodies against CD81 conjugated with 10-12 nm gold nanoparticles. SDS-PAGE and MALDI MS and MS/MS mass spectrometry of tryptic hydrolysates of proteins contained in these exosomes revealed eleven major proteins (>10 kDa): hemoglobin subunits, CD81, interleukin-1 receptor, annexin A5, cytoplasmic actin, alpha-actin-4, alkaline phosphatase, human serum albumin, serotransferrin, and lactotrasferrin. Using MALDI mass analysis of the highly purified exosomes, we for the first time found that in addition to the large proteins (>10 kDa), exosomes having affinity to CD81 contain more than 27 different peptides and small proteins of 2-10 kDa. This finding can be useful for revealing biological functions of pure exosomes. (c) 2018 IUBMB Life, 70(11):1144 1155, 2018. PMID- 30277307 TI - Perfluorooctanoic acid disrupts gap junction intercellular communication and induces reactive oxygen species formation and apoptosis in mouse ovaries. AB - Perfluorooctanoic acid (PFOA) is a member of the perfluoroalkyl acid family of compounds. Due to the presence of strong carbon-fluorine bonds, it is practically nonbiodegradable and highly persistent in the environment. PFOA has been detected in the follicular fluid of women, and positively associated with reduced fecundability and infertility. However, there are no reports concerning the experimental evaluation of PFOA on oocyte toxicity in mammals. The aim of the present study was to determine if PFOA is able to induce oxidative stress in fetal ovaries and cause apoptosis in oocytes in vitro. In addition, since inhibition of the gap junction intercellular communication (GJIC) by PFOA has been demonstrated in liver cells in vivo and in vitro, the effect of PFOA on the GJIC between the oocyte and its supportive cumulus cells was studied. Results show that PFOA induced oocyte apoptosis and necrosis in vitro (medium lethal concentration, LC50 = 112.8 MUM), as evaluated with Annexin-V-Alexa 508 in combination with BOBO-1 staining. Reactive oxygen species (ROS) levels, as assessed by DCFH-DA, increased significantly in fetal ovaries exposed to 1/4 LC50 (28.2 MUM, a noncytotoxic and relevant occupational exposure concentration) and LC50 PFOA ex vivo. This perfluorinated compound also caused the blockage of GJIC in cumulus cells-oocyte complexes (COCs) obtained from female mice exposed in vivo, as evaluated by calcein transfer from cumulus cells to the oocyte. The ability of PFOA of disrupting the GJIC in COCs, generating ROS in the fetal ovary and causing apoptosis and necrosis in mammal's oocytes, might account for the reported association between increasing maternal plasma concentrations of PFOA with reduced fertility in women. PMID- 30277308 TI - Novel T4 bacteriophages associated with black band disease in corals. AB - Research into causative agents underlying coral disease have focused primarily on bacteria, whereas potential roles of viruses have been largely unaddressed. Bacteriophages may contribute to diseases through the lysogenic introduction of virulence genes into bacteria, or prevent diseases through lysis of bacterial pathogens. To identify candidate phages that may influence the pathogenicity of black band disease (BBD), communities of bacteria (16S rRNA) and T4 bacteriophages (gp23) were simultaneously profiled with amplicon sequencing among BBD-lesions and healthy-coral-tissue of Montipora hispida, as well as seawater (study site: the central Great Barrier Reef). Bacterial community compositions were distinct among BBD-lesions, healthy coral tissue and seawater samples, as observed in previous studies. Surprisingly, however, viral beta diversities based on both operational taxonomic unit (OTU)-compositions and overall viral community compositions of assigned taxa did not differ statistically between the BBD lesions and healthy coral tissue. Nonetheless, relative abundances of three bacteriophage OTUs, affiliated to Cyanophage PRSM6 and Prochlorococcus phages P SSM2, were significantly higher in BBD-lesions than in healthy tissue. These OTUs associated with BBD samples suggest the presence of bacteriophages that infect members of the cyanobacteria-dominated BBD community, and thus have potential roles in BBD pathogenicity. PMID- 30277309 TI - Factors influencing pigment production by halophilic bacteria and its effect on brine evaporation rates. AB - The disposal of reject brine, a highly concentrated waste by-product generated by various industrial processes, represents a major economic and environmental challenge. The common practice in dealing with the large amounts of brine generated is to dispose of it in a pond and allow it to evaporate. The rate of evaporation is therefore a key factor in the effectiveness of the management of these ponds. The addition of various dyes has previously been used as a method to increase the evaporation rate. In this study, a biological approach, using pigmented halophilic bacteria (as opposed to chemical dyes), was assessed. Two bacteria, an Arthrobacter sp. and a Planococcus sp. were selected due to their ability to increase the evaporation of synthetic brine. When using industrial brine, supplementation of the brine with an iron source was required to maintain the pigment production. Under these conditions, the Planococcus sp. CP5-4 produced a carotenoid-like pigment, which resulted in a 20% increase in the evaporation rate of the brine. Thus, the pigment production capability of halophilic bacteria could potentially be exploited as an effective step in the management of industrial reject brines, analogous to the crystallizer ponds used to mine salt from sea water. PMID- 30277310 TI - The role of compatible solutes in desiccation resistance of Acinetobacter baumannii. AB - Acinetobacter baumannii is a nosocomial pathogen which can persist in the hospital environment not only due to the acquirement of multiple antibiotic resistances, but also because of its exceptional resistance against disinfectants and desiccation. A suitable desiccation assay was established in which A. baumannii ATCC 19606T survived for ca. 1 month. The growth medium slightly influenced survival after subsequent desiccation. A significant effect could be attributed to the growth phase in which bacteria were dried: In exponential phase, cells were much more desiccation sensitive. The main focus of the present study was the elucidation of the role of compatible solutes, which are known to protect many bacteria under low water activity conditions, in desiccation survival of A. baumannii. Exogenous trehalose was shown to efficiently protect A. baumannii on dry surfaces, in contrast to other compatible solutes tested such as mannitol or glycine betaine. To analyze the importance of intracellularly accumulated solutes, a double mutant lacking biosynthesis pathways for mannitol and trehalose was generated. This mutant accumulated glutamate as sole solute in the presence of high NaCl concentrations and showed severe growth defects under osmotic stress conditions. However, no effect on desiccation tolerance could be seen, neither when cells were dried in water nor in the presence of NaCl. PMID- 30277311 TI - World Health Organization life-skills training is efficacious in reducing youth self-report scores in primary school going children in Kenya. AB - AIM: Documented evidence shows that training in life skills for school going children improves their physical and mental health status. Although Kenya has a curriculum and a policy for life-skills training in schools, these have not been implemented because lack of local evidence for efficacy. Therefore, the objective of this study was to determine the efficacy and effectiveness of the life-skill training curriculum for primary schools developed by the Ministry of Education, Kenya. METHODS: We randomly selected 23 schools from two randomly selected sub counties representing urban/peri-urban and rural contexts in Kenya. We collected baseline socio-demographic characteristics and administered the locally validated youth self-report (YSR) for 11 to 18 years old at baseline and 9 months post intervention. We used the Ministry of Education validated curriculum for life skills training for upper primary school as the intervention immediately after the baseline. RESULTS: The World Health Organization life-skills training is efficacious in reducing YSR scores in primary school going children in Kenya. We found that socio-demographic characteristics were predictors for mental health and that there were significant positive improvements in internalizing and externalizing YSR symptoms and syndromes in both sites. The improvement was over 40% and therefore unlikely to be attributable to placebo effect or natural recovery without intervention. However, attention problems worsened more so in rural sites and particularly in girls. CONCLUSIONS: Life-skills training is efficacious in improving mental health in school going children in the Kenyan context. However, it is not effective in attention problems which seem to be cognitive in nature. PMID- 30277312 TI - Recent Advancements in Graphene-Based Supports of Metal Complexes/Oxides for Epoxidation of Alkenes. AB - In the past decade, there has been great progress in the preparation and catalytic applications of graphene-supported metal complexes/oxide catalysts. Graphene-based materials have attracted tremendous research interest owing to special physicochemical properties, for example, unique two-dimensional structure, high theoretical specific surface area, high electrical conductivity, and outstanding acid-base resistance properties. Graphene-supported metal complexes/oxides have been extensively investigated, and exhibit good catalytic activity and stability in water splitting (H2 generation or oxygen evolution), oxidation/epoxidation of alkenes, C-C bond formation, and so forth. Herein, recent developments in graphene-supported metal complexes/oxides for the catalytic epoxidation of different alkenes are summarized. Site isolation and synergistic interactions between metal complexes/oxides and graphene are the two key roles for enhancing the catalytic activity, whereas the hydrophobicity of the support can efficiently improve epoxide selectivity. In addition, the possible mechanisms of catalytic epoxidation are summarized. This review provides a feasible scheme for the potential application of graphene-based materials and guidance for the rational design of heterogeneous catalysts for catalytic applications. PMID- 30277313 TI - General practitioners' views towards diagnosing and treating depression in five southeastern European countries. AB - AIM: To assess and compare general practitioners' (GPs') views of diagnosing and treating depression in five southeastern European countries. METHODS: A cross sectional study was conducted in Albania, Bulgaria, Moldova, Romania, and Serbia. The sample included 467 GPs who completed a hard-copy self-administered questionnaire, consisting of self-assessment questions related to diagnosing and treating depression. RESULTS: The most common barriers to managing depression in general practice reported by GPs were: patients' unwillingness to discuss depressive symptoms (92.3%); appointment time too short to take an adequate history (91.9%), barriers for prescribing appropriate treatment (90.6%); and patients' reluctance to be referred to a psychiatrist (89.1%). Most GPs (78.4%) agreed that recognizing depression was their responsibility, 71.7% were confident in diagnosing depression, but less than one-third (29.6%) considered that they should treat it. CONCLUSIONS: Improvements to the organization of mental healthcare in all five countries should consider better training for GPs in depression diagnosis and treatment; the availability of mental healthcare specialists at primary care level, with ensured equal and easy access for all patients; and the removal of potential legal barriers for diagnosis and treatment of depression. PMID- 30277314 TI - Glucose metabolism dysregulation at the onset of mental illness is not limited to first episode psychosis: A systematic review and meta-analysis. AB - AIM: To compare the differences of glucose metabolism outcomes between treatment naive, patients with first episode psychosis (FEP) and mood disorders. METHODS: We conducted a systematic review and meta-analysis of glucose intolerance in treatment-naive, first episode patients with severe mental illnesses (SMIs). RESULTS: We identified 31 eligible studies. Compared to healthy controls, FEP group have higher insulin and insulin resistance levels, and both groups have higher glucose tolerance test results. No significant differences were found in glucose metabolism outcomes between FEP and mood disorder groups. CONCLUSIONS: Our results highlight impaired glucose metabolism at the onset of SMIs, suggesting both patients with psychosis and mood disorders are high-risk groups for diabetes development. PMID- 30277315 TI - Cryptococcal antigenemia and associated risk factors among ART-naive and ART experienced HIV-infected peoples at selected health institutions of Mekelle, Northern Ethiopia. AB - Cryptococcal infection is a major cause of opportunistic infection in HIV/AID infected peoples. We determined cryptococcal antigenemia and cryptococcal meningitis among antiretroviral therapy (ART) initiated and ART-naive HIV infected peoples. A cross-sectional study was conducted at selected health facilities in Mekelle, Ethiopia. Blood was collected to determine CD4 and plasma cryptococcal antigen (CrAg). CSF CrAg and CSF culture and urease tests were also done. Socio-demographic and clinical data were collected using a structured questionnaire and clinical chart review. From the enrolled study participants, 267 study participants had complete data, of which, 137 (51%) were females. From the study participants, 140 (52%) and 127 (48%) were ART experienced and ART naive, respectively. The prevalence of cryptococcal antigenemia was 9 (3.4%). All the study participants, except one (CD4 = 120 cells/mm3 ), had CD4 count less than 100 cells/mm3 . From CrAg-positive peoples, 6 (4.7%) were ART naive. Five CrAg-positive peoples had cryptococcal meningitis. Being male, rural residence, and being hospitalized were associated with cryptococcal antigenemia. Cryptococcal infection poses a substantial risk of HIV-positive peoples. This study provides relevant data for CrAg screening interventions in patients with low CD4 cell counts. PMID- 30277316 TI - Effects of a school teacher-led 45-minute educational program for mental health literacy in pre-teens. AB - AIM: A concise teacher-led program for mental health literacy (MHL), suitable for schools with tight schedules was developed, and its effects were examined in pre teens. METHODS: Participants comprised 662 grade 5 to 6 students from nine Japanese elementary schools. The program consisted of a 45-minute session, delivered by school teachers using a 10-minute animated film. Program focuses included: mental health problems are common, can be associated with lifestyle and that seeking help from reliable adults is a key to finding solutions. Participants filled out self-report questionnaires before, immediately after and 3 months post-intervention. Changes in MHL were analyzed using multilevel models. RESULTS: Knowledge about mental health/illnesses, recognition of mental health state and intention to help peers/seek help when suffering from mental health problems, were significantly improved immediately and 3 months post-intervention. CONCLUSIONS: Concise teacher-led programs administered in schools can have positive and lasting effects on MHL in pre-teens. PMID- 30277317 TI - Academic achievement and employment in young adults with end-stage kidney disease. AB - BACKGROUND: Young adults with end-stage kidney disease (ESKD) are at a pivotal stage of life: progressing through education, seeking employment and developing relationships. We set out to explore how ESKD impacts education and employment attainment in a matched UK and USA patient cohort. Moreover, we aimed to determine if there were significant differences in reported perceptions of impact. DESIGN: A mixed methods design combining previously validated quantitative questionnaire surveys and qualitative semi-structured interviews. PARTICIPANTS: Young people with ESKD aged 18-30 years (N = 27), attending single centre follow-up in Oxford, UK were matched with 27 comparable young people aged 19-30 years, under follow-up in Denver, USA. Twelve of these patients from Denver were selected for interview. MEASUREMENTS: Self-report questionnaires surveyed patient demographics, educational and employment achievement and experiences. Questionnaire categorical data for matched pairs were analysed using Bowker's test of symmetry. Sequential flow analyses of interview content delineated perception patterns through thematic coding. RESULTS: Sixty percent of non student Oxford participants were employed compared with 41% in Denver (p = 0.023). Forty-four percent of Oxford patients compared with 52% in Denver, reported illness had made it difficult to gain employment (p = 0.88). In Oxford, 32% completed high school as their highest educational achievement, versus 68% in Denver (p = 0.22). Qualitative themes included fatigue, self-esteem loss, social isolation and low mood. The impact of dialysis and poor understanding from educators/employers resulted in lost work time, and/or limited educational attainment. CONCLUSION: ESKD profoundly impacts on education and employment of young adults in the United States and United Kingdom, generating substantial barriers. Poor understanding appears prevalent amongst educators and employers. Healthcare providers must recognise these problems and invest resources towards tailored support in order to improve associated psychosocial and clinical outcomes. PMID- 30277318 TI - Attaining High Photovoltaic Efficiency and Stability with Multidimensional Perovskites. AB - The power conversion efficiency of organic-inorganic hybrid perovskite solar cells has soared over the past ten years and currently rivals those of crystalline silicon and other thin-film solar cells. Most of the research effort so far has been focused on three-dimensional (3 D) perovskite crystals, producing devices with very high efficiency but poor operational and environmental stability. Two-dimensional (2 D) Ruddlesden-Popper perovskite has recently shown its potential as a highly stable light absorber, albeit with low efficiency. This work reviews the current progress in attaining both high efficiency and stability in solar cells by using 2 D perovskite. In particular, the focus is on multidimensional perovskite as a way to combine the best characteristics of 3 D and 2 D perovskites. Future challenges and potential methods to boost the performance of multidimensional perovskite solar cells further are briefly presented. PMID- 30277319 TI - Contribution of structural recalcitrance to the formation of the deep oceanic dissolved organic carbon reservoir. AB - The origin of the recalcitrant dissolved organic carbon (RDOC) reservoir in the deep ocean remains enigmatic. The structural recalcitrance hypothesis suggests that RDOC is formed by molecules that are chemically resistant to bacterial degradation. The dilution hypothesis claims that RDOC is formed from a large diversity of labile molecules that escape bacterial utilization due to their low concentrations, termed as RDOCc . To evaluate the relative contributions of these two mechanisms in determining the long-term persistence of RDOC, we model the dynamics of both structurally recalcitrant DOC and RDOCc based on previously published data that describes deep oceanic DOC degradation experiments. Our results demonstrate that the majority of DOC (84.5 +/- 2.2%) in the deep ocean is structurally recalcitrant. The intrinsically labile DOC (i.e., labile DOC that rapidly consumed and RDOCc ) accounts for a relatively small proportion and is consumed rapidly in the incubation experiments, in which 47.8 +/- 3.2% of labile DOC and 21.9 +/- 4.6% of RDOCc are consumed in 40 days. Our results suggest that the recalcitrance of RDOC is largely related to its chemical properties, whereas dilution plays a minor role in determining the persistence of deep-ocean DOC. PMID- 30277320 TI - Impact of Phaeobacter inhibens on marine eukaryote-associated microbial communities. AB - Bacteria-host interactions are universal in nature and have significant effects on host functionality. Bacterial secondary metabolites are believed to play key roles in such interactions as well as in interactions within the host-associated microbial community. Hence, prominent secondary metabolite-producing bacteria may be strong drivers of microbial community composition in natural host-associated microbiomes. This has, however, not been rigorously tested, and the purpose of this study was to investigate how the secondary metabolite producer Phaeobacter inhibens affects the diversity and composition of microbiomes associated with the microalga Emiliania huxleyi and the European flat oyster, Ostrea edulis. Roseobacters were indigenous to both communities exhibiting relative abundances between 2.8% and 7.0%. Addition of P. inhibens caused substantial changes in the overall structure of the low-complexity microbiome of E. huxleyi, but did not shape microbial community structure to the same degree in the more complex oyster microbiomes. Species-specific interactions occurred in both microbiomes and specifically the abundances of other putative secondary metabolite-producers such as vibrios and pseudoalteromonads were reduced. Thus, the impact of a bioactive strain like P. inhibens on host-associated microbiomes depends on the complexity and composition of the existing microbiome. PMID- 30277321 TI - Absence of infratentorial lesions in Fabry disease contributes to differential diagnosis with multiple sclerosis. AB - BACKGROUND AND PURPOSE: Multiple Sclerosis (MS) has been proposed as a possible differential diagnosis with Fabry Disease (FD). We evaluated the incidence of infratentorial lesions in FD patients, investigating whether their presence could help in differentiating these two conditions. We explored the diagnostic accuracy of this sign alone and in combination to the involvement of corpus callosum (CC). METHODS: White Matter lesions were retrospectively evaluated on FLAIR images available from 136 MS and 144 FD patients. Infratentorial involvement was assessed considering the whole cerebellum, and the part of the brainstem included between the occipital foramen and the upper edge of the red nucleus. Furthermore, the presence of callosal lesions was also recorded, evaluating the portion of CC included between the two external walls of the lateral ventricles. RESULTS: Infratentorial involvement was detectable in 119/136 (87.5%) MS patients, while it was present in only 17/144 (11.8%) FD patients. When the diagnostic performance of a positive infratentorial involvement was evaluated in combination with the presence of CC lesions, a specificity of 97%, with a positive predictive value of 96% was reached. CONCLUSIONS: We concluded that the absence of infratentorial lesions, especially when combined to the evaluation of other typical imaging features, can help in the differential diagnosis between MS and FD.

AB - Temperature is an important parameter for the performance of bioelectrochemical systems (BESs). Energy-intensive bulk water heating has been usually employed to maintain a desired temperature for the BESs. This study concerns a proof-of concept of a light-to-heat photothermal electrode for solar heating of a local electroactive biofilm in a BES for efficient microbial energy harvesting at low temperatures as a replacement for bulk water heating approaches. The photothermal electrode was prepared by coating Ti3 C2 Tx MXene sunlight absorber onto carbon felt. The as-prepared photothermal electrode could efficiently raise the local temperature of the bioelectrode to approximately 30 degrees C from low bulk water temperatures (i.e., 10, 15, and 20 degrees C) under simulated sunlight illumination. As a result, highly efficient microbial energy could be harvested from the low-temperature BES equipped with a photothermal electrode without bulk water heating. This study represents a new avenue for the design and fabrication of electrodes for temperature-sensitive electrochemical and biological systems.

AB - AIM: The aim of this study was to examine an emergency department's (ED) multidisciplinary teams' (MDTs) attitudes towards an advanced nurse practitioner (ANP) service. The ED in question is not the author's place of work. METHOD: A Likert-type questionnaire was used to gain a total attitude score (TAS), which was analysed in relation to participants' gender, age, professional background, level of education and years of experience in the ED, as well as previous and current contact with emergency nurse practitioners and/or ANPs. A total of 115 questionnaires were distributed, and respondents included doctors, nurses, managers, pharmacists, radiographers and a physiotherapist. Participants provided qualitative data to explain their choices, and were asked to describe positive and negative aspects of an ANP service. The data were analysed using a mixed methods approach. FINDINGS: The TASs were generally positive and there were no statistical differences between the professional groups, although there was some resistance from participants. CONCLUSION: Overall, the MDT believes the ANP service will improve patient care, waiting times, team divisions and patients' experiences in the ED if the roles and responsibilities are clearly defined and communicated. In addition, the service should receive enough funding to ensure its sustainability and appropriate supervision by a senior doctor should be made available. PMID- 30277347 TI - [Use of Fundamental Properties of Embryonic Objects for Studying Potential Environmental Effects of Technogenic Impacts]. AB - This article analyzes the problems of biosafety in terms of individual development patterns. Previously,the key role of epigenetic free radical processes in normal embryonic development of lower vertebratesin the formation of the competence and determination of embryonic primordia has been demonstrated, anda significant increase in the intensity of free radical process before every qualitative change in homeostaticmechanisms in developing organisms was found: in induction systems, before hatching of the embryo fromthe shells, and in preparation for metamorphosis. Thus, the activation of free radical processes in embryonicprimordia corresponds to instability and characterizes the "critical periods of development" and increasedsensitivity of the embryo to environmental impacts. Patented methods and a test system that allows detectingearly biological effects of weak environmental impacts and predicting their environmental risk are presented.Possible mechanisms of significant biological effects of weak radiation and chemical impacts on the developingorganism are discussed. The necessity of including embryonic objects in the protocol of testing the biosafetyof technological developments is substantiated.

The contribution to recovery of pigmentation of the injuredarea of de novo differentiation of melanophores is compared to contribution of mitotic division of undamagedmelanophores localized on the boundaries of the injured area. The regeneration process is observed duringvarious stages of pigment system development of larvae. We establish that, compared to ontogenetic dynamics,pigmentation development in animals is more intense during the regeneration.

AB - Impact of the allogenic tissue transplantation of the fetal cerebral large hemispheres and the olfactory bulb tissue (OBT) on the healing processes after the brain contusion was studied in experiment. The investigation was performed on mongrel male rats: in laboratory animals of the first group in the first day after open penetrating local cerebral trauma (OPLCT) the allogenic fetal nervous tissue fragment was transplanted into the formatted tissue defect; for the second group - in the first day after cerebral trauma the allogenic OBT fragment was transplanted into the formatted tissue defect; and for the third group (control) the OPLCT was done without further transplantation of tissues. The impact of the allogenic fetal nervous tissue transplantation was demonstrated by more active participation of glial cells during the healing process course, and the OBT transplantation was followed by activation of neoangiogenesis processes , mainly in the injured brain. The experimental simulation choosed permits to study the possibilities of application of neurogenic tissues in the brain contusion treatment, and to determine the therapy tactics.

The defect, occurring after resection of the oral cavity floor together with the mandibular anterior fragment, constitutes the most complex one for the plasty performance. The main principles of the defects plasty were determined. The plastic material choice depends on peculiar clinical situation, the surgical intervention volume, the defect localization and its size.

AB - Objectives: To establish the differences in social support, resilience, coping, and three burnout dimensions (emotional exhaustion, depersonalization, and reduced personal accomplishment) among special units nursing and nursing staff of others hospital services; as well as to determine psychological variables that predict burnout in these professionals. Method: Correlational and cross-sectorial study. A sample of 133 nursing professionals from University Hospital of Fuenlabrada (Madrid) took part in the study, of whom 61 worked in special units and 72 in wards. Instruments: Maslach Burnout Inventory-Human Services Survey (MBI-HSS), Social Support Subscale, 10-Item CD-RISC (resilience), Brief-Cope (coping), and sociodemographic variables. Results: No differences were found in any assessed psychological variables as regards hospital service worked in. Social support, resilience and coping strategies determined three burnout dimensions: social support (beta = -0.21, support coping (beta = -0.22) and disengagement coping (beta = 0.22) predicted emotional exhaustion; resilience (V = -0.22) and disengagement coping (beta = 0.30) predicted depersonalization; and engagement coping (beta = -0.55) predicted reduce personal accomplishment. Conclusions: Differences in burnout, social support, resilience and coping strategies are not determined by hospital service. Social support, resilience, engagement coping, and support coping (adaptives) constitute three tools to face burnout in nursing. These tools could be developed by specific programs from universities and health institutions to improve nursing clinical practice. PMID- 30277360 TI - [Developmental Aspects of Senescence].

AB - The transformation of polyp into medusa is one of the most interesting processes in the life cycleof cnidarians. In the polyps of the class Scyphozoa this transformation occurs in the form of strobilation,which is the transverse fission of polyps with the formation of discoidal ephyrae. At present, the endogenousregulation of strobilation in one of scyphozoans, Aurelia aurita, is being investigated by the methods of molecularbiology (Fuchs et al., 2014). However, it is still unclear which key environmental factors induce this process.The main purposes of this review are to summarize the literature data on the conditions in which strobilationin A. aurita occurs in nature and in the laboratory and to try to identify the environmental factors thatare most likely to play a signaling role in strobilation.

AB - This article is devoted to the study of the double fertilization mechanism in plants, in particular ofthe maize gamete membrane fusion genes. We detected and analyzed for the first time gamete-fusion genesin the maize genome. Using the BLAST program, we searched for the hap2 gene (generative cell specific 1(gcs1)) homologs from Arabidopsis in the maize genome. The ZM_BFb0162K03 maize transcript was found,which had 67% identity to the Athap2 gene and contained a conserved region similar to the Athap2 gene fragment.In mRNA samples from the haploid inducing and control maize lines, an PCR was conducted by usingprimers specific to the ZM_BFb0162K03 sequence fragment. Sequences of the PCR products from a fragment(1467 bp) of the Zm_hap2 gene of the haploid-inducing and the control maize lines were identical andalso were identical to the maize sequences from the GenBank (ZM_BFb0162K03). PCR products (656 bpregion of Zm_hap2) for the ZM_BFb0162K03 (1925 bp) maize sequence were observed for the cDNA of pollengrains, ovary, leaves, and roots of the haploid-inducing and control maize lines. Using the Blastx program,we found significant homology of the maize translated proteins to the GEX2, TET11, and TET12 proteins,involved in Arabidopsis gamete-fusion contacts.

AB - As established by us earlier, ethylene behaves as a regulator of germination, development, andgrowth of male gametophyte during the progamic phase of fertilization. However, the mechanisms of the regulationof these processes remain so far unstudied. It is believed that the main factor providing variety of theethylene responses is its interaction with other phytohormones. According to our working hypothesis, ethylenecontrols germination of pollen grains (PGs) and growth of pollen tubes (PTs) by interacting with auxin,which, as the available data indicate, is likely a key regulator of plant cell polarization and morphogenesis andone of the factors modulating the biosynthesis of ethylene at the level of ACC-synthase gene expression. Inthe present work, on germinating in vitro male gametophyte and the pollen-stigma system for petunia (Petuniahybrida L.) effects of phytohormones (ethylene and IAA) and known blockers repressing ethylene reception(1-methylcyclopropene, 1-MCP), the synthesis of ACC (amino oxyacetic acid, AOA) and transport IAA(triyodbenzoynaya acid, TYBA) on PGs germination, PTs growth and the synthesis of ACC were investigated.According to the data obtained, exogenous ethylene and IAA stimulated both PGs germination andPTs growth. 1-MCP and TYBA completely inhibited the first process, whereas IAA abolished the inhibitoryaction of 1-MCP and AOA on both the above processes. Etrel only partially weakened the inhibitory effect ofTYBA. Examination of ACC synthesis modulation with AOA showed that IAA does not affect the level ofACC in germinating in vitro male gametophyte and nonpollinated stigmas, while this phytohormone insignificantlyraised the level of ACC and abolished the inhibitory effect of AOA on its synthesis in the pollenstigmasystem. Pollination of stigmas with the pollen preliminarily treated with 1-MCP led to 2.5-fold declinein both the rate of PT growth and the level of ACC. At the same time, IAA abolished the inhibitory action of1-MCP recovering the synthesis of ACC and growth of PTs to the control values. All these results, takentogether, provide evidence for the interaction of the signal transduction pathways of ethylene and auxin at thelevel of ACC biosynthesis in the course of germination and growth of petunia male gametophyte during theprogamic phase of fertilization.

AB - Neuronal development of the majority of trochozoan animals with biphasic pelago bentic lifecycle starts from transient peripheral neurons, which do not belong to the central nervous system and aremainly located in the apical sensory organ and in the hyposphere. Some of these neurons are pioneer and sendneurites that form a scaffold upon which the adult central nervous system later develops. In representativespecies of molluscs and polychaetes, immunolabelling with the antibodies against neurotransmitters serotoninand FMRFamide, and acetylated alpha tubulin revealed that the structure of almost all early peripheralneurons is typical for sensory, most probably chemosensory cells: flask shape, and cilia at the end of the apicaldendrite or inside the distal ampoule. Morphology, transmitter specificity, location and projections of theearly sensory cells differ in trochophores of different species thus suggesting different origin of these cells. Inpolychaete larvae, pharmacological inhibition of serotonin synthesis in early peripheral neurons did not affectthe development, whereas its increase resulted in developmental arrest and neural malformations, suggestingthat early peripheral sensory neurons are involved in developmental regulation.

AB - Terahertz radiation (0.1-10 THz) is increasingly becoming a factor of human habitat. The studyof the consequences of radiation allows one to estimate its possible biological danger. Our data indicate thatthe terahertz irradiation of parental Drosophila shortens the period of embryonic development of their firstgeneration descendants. Significant deviations of data from the control were found, when both females andmales were experimental parents. The highest portion of animals with accelerated hatching as compared withthe control was found in progenies from irradiated females. The shift of maximal hatching peak to an earlierperiod was found in descendants of both sexes. Thus, it was for the first time found on the model object (Drosophila)that the terahertz irradiation of parents can have positive or negative consequences in the first generationdescendants.

AB - The progress of ontogenesis is analyzed in four members of the genus Trfolium, Lupinaster sectionand it is shown that the ecological conditions have a guiding influence on the course of individual developmentof the species. The most important among them are: soil mechanical composition, distance from theseashore, regime and intensity of moistening. Six variants of the ontogenesis, having two subvariants for threeof them, were allocated for the members of the section. The initial stages of the ontogenesis are similar, butthe main differences begin to manifest from the virginal age. Evolutionary transformation within the sectionare expressed in reduced leaflets of compound leaves, weakened functioning of the main root, rhizome development,and the transition of perennial forms to vegetative biennials.

AB - Objective: Measure the validity, reliability and consistency of two alternative diagnostic systems, Nurse Pediatric Emergency Assessment for Primary Care system (VEUPAP) and web_e-PAT(r), using expert pediatricians judgment as a gold standard. Material and Methods: Random sample of 300 children aged 0-14 years treated at the Pediatric Urgency Service Dr. Jaime Chaves in Santa Cruz de Tenerife between March 2009 and March 2010. Demographics data, time, presentation of complications and referrals to high, triage results according VEUPAP and web_e PAT(r), medical discharge and interview results to escort the child report, were registered. Sensitivity, specificity, frequency of false positive and negative predictive values of results, their concordance with the gold standard, and reliability of both methods, were estimated. Results: VEUPAP offers better values that web_e-PAT(r) with sensitivity 94% (95% Cl: 91-97%) vs. 36% (95% Cl: 31-41%), specificity 93(90-96)% vs. 87(83-91)%, positive predictive value of 89 (86-92)% vs. 63(58-68)%, and negative 96(94-98)% vs. 69(64-74)%, yield a4 vs. 3 times more, according to expert pediatrician 84(80-88)5 vs. 12(9-15)% reliability and 64(59-69)% vs. 59(54-63)% according to the weighted kappa Cohen (p < 0.001). Three levels lower and upper of triage discrepancies do not occur with any of the systems, the discrepancy in lower and upper triage at 2 levels do not occur with VEUPAP and is 14% and 4% respectively with web_e-PAT(r) (p = 0.032-0.045). Most of the discrepancies occur with triage level 1 being for VEUPAP 2-8% and 10-36% for web_e-PAT(r) (p < 0.001). The time consumption for both systems reached significance only for priority level 3: 4 (2-7) vs. 4 minutes (2-14), respectively (p = 0.044). Conclusions: VEUPAP is a homogeneous and systematic objective tool. The characteristics of accuracy, validity, accuracy, reliability, usefulness and ease of use make it suitable to assessment and classification pediatric patients in primary care emergency. PMID- 30277369 TI - [Evaluation of the BD Phoenix ID Yeast System for the Species Identification of Clinical Yeast-Like Organisms]. AB - Most fungi isolated from patients with deep-seated mycosis are yeast-like organisms such as Candida and Cryptococcus. As their respective susceptibilities to antifungal agents can vary depending on the species, rapid identification is important for the administration of appropriate antifungal therapy. The aim of this study was to evaluate the performance of a new automated identification panel, Phoenix Yeast ID (Becton, Dickinson Diagnostics, USA) as well as the time required for identification. The identification results of 106 isolates generated by this system were then compared with those of the API 20C AUX system (SYSMEX bioMerieux Co., Ltd. Japan). Among the 106 isolates, the identification agreement between the two yeast panels was 97/106 (91.5%). Of the 9 (8.5%) discrepant identifications, 5 identification using the Phoenix Yeast ID system and 1 identification using the API 20C AUX system agreed with the genotypic identification. Genotypic identification did not agree with the Phoenix Yeast ID or API 20C AUX findings for the remaining 3 discrepant identifications.Approximately 60% of the C. albicans, C. tropicalis, and C. parapsilosis isolates were identified within 4 hours. In total, about 90% of the 4 major Candida sp. (C. albicans, C. tropicalis and C. glabrata) were identified within 8 hours. In conclusion, the Phoenix Yeast ID findings agreed well with the API 20C AUX findings. Genotypic identification of the discrepant identifications confirmed most of the Phoenix Yeast ID panel identifications. As approximately 80% of the major Candida sp. could be identified within 8 hours using the Phoenix Yeast ID identification system, our results suggest that this system is a clinically useful addition to commercially available yeast identification panels. The Phoenix Yeast ID system showed excellent concordance with genotypic identification for the classification of organisms with discrepant API 20C AUX findings.

AB - In 2013, two outbreaks of enterohemorrhagic Escherichia coli (EHEC) occurred in Saitama city. According to reports from each of the medical institutions that detected the EHEC isolates, the isolates seemed to differ in their production of Vero Toxin (VT / Shiga Toxin: Stx) since one isolate produced only Stx1 and the other produced both Stx1 and Stx2. However, a patient survey conducted by a public health center revealed that common foodstuffs had been consumed in both outbreaks. Because, the two EHEC isolates were newly detected from two people in one patient's family, we analyzed the phenotypic and genetic relationships among four isolates in total. All the isolates were serotyped as O157: H-, and both stx1 and stx2 were detected. Subsequently, all four isolates were shown to have the same pulsed-field gel electrophoresis (PFGE) banding pattern. The findings suggested that these isolates belonged to the same strain group. Among these cases, the isolates had stx2c which is one of the stx2 subtypes. Reportedly, some cases with the Stx2 subtype can not be detected using conventional tests for toxin. In addition, Stx2 can be overlooked as a result of this limitation of Stx production tests. Both epidemiological research by public health centers and genetic analysis by prefectural and municipal public health institutes (PHIs) are very important for clarifying possible relationships among outbreaks, as in the present cases. Moreover, collaborations and networks among medical institutions, PHIs and public health centers should be further strengthened to prevent the spread of infections. PMID- 30277371 TI - [Syphilis Testing and High Rate of Infection Among HIV-infected Patients]. AB - Background: The incidence of syphilis has globally increased over the last decade, particularly among men who have sex with men coinfected with the human immunodeficiency virus (HIV). HIV infection may make the clinical symptoms and seroreactivity of syphilis atypical, which requires careful consideration in terms of diagnoses and treatments by clinicians. Syphilis is known as a great imitator, and is often difficult to be diagnosed or it can be overlooked if clinicians depend only on its symptoms or signs. It is also highly contagious and could be transmitted without sexual intercourse, and reinfection is common. Guidelines recommend that all HIV-infected persons be provided with STD screening, including syphilis, at least annually. However, to our knowledge, there are no published data on the actual frequency of testing and instances of syphilis among HIV-infected persons in Japan. Materials and Methods: We collected data from HIV infected male patients who had sex with men (MSM) at Tokyo Medical University Hospital from June 2011 to June 2012. Data from the patients, who had been tested with the rapid plasma reagin assay (RPR) at least once during the study period, were retrospectively obtained from clinical records and were analyzed. Results: Among 1000 patients with HIV infection, 935 patients were MSM. 723 patients (77.4%) were tested using the Treponema pallidum latex agglutination test (TPLA) and RPR more than once during the study period. Out of the 723 patients, 443 patients (61.3%) were reactive for TPLA and 238 patients (32.9%) had reactive tests for RPR. All patients who were reactive for RPR were reactive for TPLA. Among the patients who were reactive for RPR, 93 patients (12.9%) were considered newly diagnosed or with a repeat infection. In this cohort, all patients were MSM with a median age of 37 years, and a median CD4+T-lymphocyte cell count of 465/uL. A total of 76 patients had been prescribed antiretroviral therapy, and 61 patients had a documented HIV-1 RNA viral load of <40 copies/mL at their most recent test. Two patients both developed two episodes of syphilis during the study period. Of the 95 episodes, 44% were symptomatic syphilis and the most common symptom among them was a skin rash at the second stage. Nearly half of the patients (47%) were diagnosed at regular screenings. Two thirds (67%) had syphilis infections before the study period, whereas at least 20% of them were newly diagnosed during the study period. Conclusions: A substantial percentage of the participants were newly or recurrently diagnosed with syphilis during the study period. More public health awareness should be encouraged regarding the current epidemic of syphilis among HIV-infected persons in Japan. It is also important for clinicians to provide HIV-infected persons with periodical syphilis screening, regardless of the apparent clinical signs or symptoms to achieve earlier treatment intervention.

AB - Introduction: The channeling of central venous catheters (CVC) is a technique used in intensive care units (ICUs) but it doesn't come without the risk of infection in the placement and subsequent handling. Objective: Evaluate the effectiveness of a prevention of infection following the introduction of new multifactorial strategies in the prevention program Central line-associated bloodstream infection (CLABSI) at ICU. Methodology: Comparative descriptive study in two periods, including all patients admitted in multipurpose ICUs of a tertiary hospital 2014. We analyzed 2014 data compared with 2013, to test the impact of new measures CRB prevention program. Variables: number of catheters, number of infections/1000 catheter days and path. Actions carried out were: prospective surveillance of the incidence rate, sequential program multifactorial prevention implementation of different measures, checklist for insertion of new catheters, introduction of weekly monitoring compliance, reporting episodes team are, continuing education for sanitary personal and implementation of the semipermeable transparent dressings with chlorhexidine gel. Results: The overall incidence density rate decreased from 3.1 episodes/1000 catheter days in 2013 to 2.3 episodes/1000 catheter days in 2014, improving in different units. The utilization ratio of the different accesses was: 35% humeral; 33% jugular; 25% subclavian; 10% femoral, and 13% hemodialysis catheter. Conclusions: The new measures applied to reduce the bacteremia have allowed a decrease in the rate of infection, what brings closer to the objective of the Bacteremia Zero program.

AB - We report a case of iatrogenic vesical tuberculosis diagnosed 4 years after intravesical immunotherapy using Bacillus Calmette- Guerin (BCG) for the treatment of bladder carcinoma.A 72-year-old man underwent a transurethral resection (TUR) of multiple noninvasive urothelial carcinomas and intravesical BCG infusion (40 mg/week) for 7 weeks to prevent the recurrence of bladder carcinoma. BCG infusion therapy was terminated because of the appearance of Reiter's syndrome, including arthritis of the left toe joint, conjunctivitis and non-gonococcal urethritis as complications. The patient suffered from repeated cystitis, bladder atrophy and urethral stenosis.The cystitis improved with the administration of antibiotics (Levofloxacin) but persisted without a complete cure. Four years later, a cystoscopy revealed mucosal erosion and a white coating. An acid-fast bacteria examination of a urine sample using bacteria incubation and DNA PCR revealed the presence of Mycobacterium bovis. Finally, anti-tuberculosis therapy (INH+REP+EB) was initiated after the patient was diagnosed as having iatrogenic bladder tuberculosis resulting from BCG immunotherapy. The tuberculosis bacteria subsequently disappeared from the urine samples, and the gross appearance of the bladder mucosa improved. Bladder carcinoma has not recurred to date.Intravesical BCG infusion therapy has a good anti-tumor effect and can help prevent tumor recurrence after TUR therapy in case of noninvasive bladder carcinoma. However, there is a risk of severe complications arising from the BCG infusion. In the present case, an adequate bacteria examination was not performed, even though antibiotics were repeatedly administered for cystitis. In particular, the patient was not tested for the presence of acid-fast bacteria for 4 years after the intravesical BCG infusion therapy. Furthermore, among patients who received anti-bacteria therapy for repeated cystitis after BCG infusion, a bacteria examination including bacteria incubation, was not ordered in 19 out of 30 cases treated at our hospital over the past 5 years. In conclusion, bacteria examination, including tests for acid fast bacteria, should be immediately performed when repeated and/or persistent cystitis occurs after BCG infusion therapy.

AB - We report a 48-year-old healthy man who presented with a 1-week history of fever and epigastric pain. He had traveled to Indonesia and had been in sexual contact with a local woman 4 weeks prior to admission. His peripheral blood film showed atypical reactive lymphocytes. A serological test for cytomegalovirus IgM was positive and the quantitative cytomegalovirus DNA level was 1.1*102 copies/mL, whereas Epstein-Barr virus IgM, HIV antigen and antibody tests were negative. He was diagnosed as having an acute cytomegalovirus infection and was treated with acetaminophen. However, his clinical symptoms deteriorated on the 4th day after admission and a computed tomography examination showed splenomegaly with wedge shaped splenic infarctions. Blood culture, antinuclear antibodies, antineutrophilic cytoplasmic antibodies, anti-cardiolipin antibodies, and lupus anticoagulant tests were negative. The protein C and protein S activities were normal. He was diagnosed as having a splenic infarction caused by an acute cytomegalovirus infection, and intravenous heparin administration was performed. On day 12, his symptoms had improved and he was discharged. Splenic infarctions caused by acute cytomegalovirus infection can develop in immunocompetent patients without any coagulation disorder. The possibility of splenic infarctions should be considered in patients with acute cytomegalovirus infection, especially those experiencing a worsening of abdominal pain. PMID- 30277376 TI - Impact of Strain-Induced Changes in Defect Chemistry on Catalytic Activity of Nd2NiO4+delta Electrodes. AB - It is well known that defect chemistry plays a vital role in determining the electronic structure, ionic conductivity, and catalytic activity of metal oxides, as demonstrated in perovskite-based oxides to achieve desired functionalities. In this work, we explored the possibility of tuning the defect chemistry and hydrogen oxidation reaction (HOR) activity of Nd2NiO4+delta model thin films by controlling the lattice strain. Highly textured Nd2NiO4+delta thin films with different strain states were prepared on (110)- and (100)-oriented single-crystal yttrium-stabilized zirconium (YSZ) substrates using pulsed laser deposition. Electrochemical impedance spectroscopy results indicated that the NNO(100) film on the YSZ(110) substrate with larger tensile strain in the a- b plane and compressive strain along the c axis exhibited higher HOR activity than the NNO(110) film on the YSZ(100) substrate at 500-600 degrees C. The enhancement in HOR activity is attributed to the strain-induced difference in the oxygen defect concentration, as confirmed by high-resolution X-ray diffraction analysis. We believe that the correlation among the strain state, defect chemistry, and catalytic properties is helpful for rational design of more efficient electrode materials.

AB - Introducing genes into drug-delivery system for a combined therapy has become a promising strategy for cancer treatment. However, improving the in vivo therapy effect resulted from the high delivery efficiency, low toxicity, and good stability in the blood remains a challenge. For this purpose, the supramolecular inclusion was considered to construct a high-efficiency drug and gene co-delivery system in this work. The oligoethylenimine-conjugated beta-cyclodextrin (beta-CD PEI600) and benzimidazole-modified four-arm-polycaprolactone-initiated hyperbranched polyglycerol (PCL-HPG-BM) were synthesized as the host and guest molecules, respectively, and then the co-delivery carrier of PCL-HPG-PEI600 was formed from the pH-mediated inclusion interaction between beta-CD and BM. PCL-HPG PEI600 showed the improved drug (doxorubicin, DOX) and gene (MMP-9 shRNA plasmid, pMMP-9) delivery ability in vivo, and their cellular uptake and intracellular delivery were investigated. Particularly, PCL-HPG-PEI600 showed excellent pMMP-9 delivery ability with significantly higher transfection efficiency than PEI25k due to its excellent serum resistance. For the combined therapy to breast cancer MCF-7 tumor, the co-delivery system of PCL-HPG-PEI600/DOX/pMMP-9 resulted in a much better inhibition effect on MCF-7 cell proliferation and migration in vitro as well as the suppression effect on MCF-7 tumors in vivo compared to those of single DOX or pMMP-9 formulation used. Moreover, PCL-HPG-PEI600 displayed nontoxicity and excellent blood compatibility, suggesting a promising drug and gene co-delivery carrier in combined therapy to tumors. PMID- 30277377 TI - A New Type of Three-Dimensional Hybrid Polymeric Haloplumbate Based on Rare High Nuclear Heterometallic Clusters. AB - A series of new three-dimensional hybrid heterometallic haloplumbates [Pb8M(MU3 O)2X8(XH)(eg)3] n {H2eg = ethylene glycol; X = Cl, M = Co (1a), Ni (1b), Zn (1c); X = Br, M = Ni (2a), Zn (2b); X = I, M = Zn (3)} have been solvothermally synthesized and structurally characterized. Compounds 1a-c, 2a-b, and 3 consist of one-dimensional haloplumbate [Pb2X9] chains, and heptanuclear heterometallic [Pb6M(MU3-O)2(eg)3] clusters based on two [Pb3(MU3-O)(eg)1.5] cores share one M2+ ion, which are interconnected to generate three-dimensional heterometallic frameworks. Although a few heterometallic haloplumbates incorporating other metal complexes have been reported, they usually exhibit low-dimensional structures. The present heterometallic haloplumbates offer good examples of applying high nuclear heterometallic [Pb6MO2(eg)3] clusters to construct a new type of high dimensional hybrid heterometallic haloplumbate. Compounds 1a-b and 2a indicate unusual ferrimagnetic behavior. Their optical properties are investigated at room temperature, and density functional theory calculations of compounds 1c, 2b, and 3 are also studied. PMID- 30277378 TI - Injection-Molded Microfluidic Device for SERS Sensing Using Embedded Au-Capped Polymer Nanocones. AB - To enable affordable detection and diagnostic, there is a need for low-cost and mass producible miniaturized sensing platforms. We present a fully polymeric microfluidic lab-on-a-chip device with integrated gold (Au)-capped nanocones for sensing applications based on surface-enhanced Raman spectroscopy (SERS). All base components of the device were fabricated via injection molding (IM) and can be easily integrated using ultrasonic welding. The SERS sensor array, embedded in the bottom of a fluidic channel, was created by evaporating Au onto IM nanocone structures, resulting in densely packed Au-capped SERS active nanostructures. Using a Raman active model analyte, trans-1,2-bis-(4-pyridyl)-ethylene, we found a surface-averaged SERS enhancement factor of ~5 * 106 with a relative standard deviation of 14% over the sensor area (2 * 2 mm2), and a 18% signal variation among substrates. This reproducible fabrication method is cost-effective, less time consuming, and allows mass production of fully integrated polymeric, microfluidic systems with embedded high-density and high-aspect ratio SERS sensor. PMID- 30277379 TI - Restriction Enzyme Analysis of Double-Stranded DNA on Pristine Single-Walled Carbon Nanotubes. AB - Nanoprobes such as single-walled carbon nanotubes (SWCNTs) are capable of label free detection that benefits from intrinsic and photostable near-infrared fluorescence. Despite the growing number of SWCNT-based applications, uncertainty surrounding the nature of double-stranded DNA (dsDNA) immobilization on pristine SWCNTs has limited their use as optical sensors for probing DNA-protein interactions. To address this limitation, we study enzyme activity on unmodified dsDNA strands immobilized on pristine SWCNTs. Restriction enzyme activity on various dsDNA sequences was used to verify the retention of the dsDNA's native conformation on the nanotube surface and to quantitatively compare the degree of dsDNA accessibility. We report a 2.8-fold enhancement in initial enzyme activity in the presence of surfactants. Forster resonance electron transfer (FRET) analysis attributes this enhancement to increased dsDNA displacement from the SWCNT surface. Furthermore, the accessibility of native dsDNA was found to vary with DNA configuration and the spacing between the restriction site and the nanotube surface, with a minimum spacing of four base pairs (bp) from the anchoring site needed to preserve enzyme activity. Molecular dynamics (MD) simulations verify that the anchored dsDNA remains within the vicinity of the SWCNT, revealing an unprecedented bimodal displacement of the bp nearest to SWCNT surface. Together, these findings illustrate the successful immobilization of native dsDNA on pristine SWCNTs, offering a new near-infrared platform for exploring vital DNA processes.

In this work, we report diblock molecular beacons with poly-cytosine (polyC) tails anchored on molybdenum disulfide (MoS2) nanosheets as probes for microRNA detection. The polyC block is adsorbed on MoS2 and the molecular beacon block is available for hybridization to the target; duplex-specific nuclease provides signal amplification by target recycling. By changing the length of polyC, we regulate the density of probes on MoS2 and inhibit the adsorption of enzyme cleaved oligonucleotides, thereby leading to higher quenching efficiency. PolyC mediated molecular beacons on MoS2 have very low background signal, ultrahigh sensitivity (limit of detection ~3.4 fM), specificity to detect a single nucleotide mismatch, and selectivity to detect target microRNA from serum samples. This detection platform holds great potential for quantitative analysis of miRNAs in clinical diagnosis and biomedical research.

AB - Three pentacoordinate complexes of the type [Co( pypz)X2], where pypz is a tridentate ligand 2,6-bis(pyrazol-1-yl)pyridine and X = Cl- (1), NCS- (2), and NCO- (3), have been synthesized, and their structures have been determined by X ray analysis. The DC magnetic data show a sizable magnetic anisotropy, which was confirmed by high-field high-frequency electron paramagnetic resonance (HF EPR) measurements. Well-resolved HF EPR spectra of high spin cobalt (II) were observed over the microwave frequency range 100-650 GHz. The experimental spectra of both complexes were simulated with axial g tensor components, a very large positive D value, and different E/ D ratios. To determine the exact D value for 2 (38.4 cm 1) and 3 (40.92 cm-1), the far-infrared magnetic spectroscopy method was used. Knowledge of the zero field splitting parameters and their signs is crucial in interpreting the single-molecule magnet or single chain magnet behavior. The AC susceptibility data confirm that these complexes exhibit a slow magnetic relaxation under small applied DC field with two (1 and 3) or three (2) relaxation modes.

AB - Dirac half-metals have drawn great scientific interests in spintronics because of their outstanding physical properties such as the large spin polarization and massless Dirac fermions. By using first-principles calculations, we investigate the perovskite-type lanthanum manganite (LaMnO3) as a novel Dirac half-metal. Specifically, LaMnO3 displays multiple linear band crossings in the spin-up direction, while it has a large band gap (~5 eV) in the spin-down orientation. The intriguing linear band dispersions guarantee the ultrafast electron transport and the significant band differences between spin up and down directions promise the realization of 100% spin-polarized current and the extremely low energy consumption. Such a spin-polarized Dirac material is rare among perovskite-type compounds. By adopting the mean-field theory, the estimated Curie temperature Tc is 438.4 K. Importantly, the LaMnO3 crystal has been experimentally realized 2 decades ago, which facilitates the future experimental validation. With the novel spin-polarized electronic properties and the high possibility of experimental fabrication, LaMnO3 is ideal for the spintronic application.

AB - Here, we present a series of experimental studies to encapsulate ultrasmall gold nanoparticles into mesoporous metal oxide via an in situ self-assembly method. Notably, the 2.0Au@mZnO catalyst (~2.0 nm gold nanoparticles loading on mesoporous ZnO nanospheres) shows excellent catalytic activity for indane oxidation (120 degrees C, conversion 88.5%) and affords much high turnover frequencies (9521 h-1). The catalytic activity of these gold-based catalysts was found to be correlated with the size of gold nanoparticles and the types of metal oxide supports. With a decrease in gold nanoparticle size, the catalytic conversion efficiency of indane oxidation increased. In addition, such catalysts possessed high thermal and chemical stability and could be reused more than 10 times without a remarkable loss of catalytic activity. PMID- 30277384 TI - Design of Robust Thermal and Anion Dual-Responsive Membranes with Switchable Response Temperature. AB - In this study, poly(ionic liquids/ N-isopropylacrylamide) (PIL/NIPAM) modified poly(ether sulfone) microporous membranes were prepared using a pore-filling method. Due to the anion-sensitive wettability of the PIL and the thermal sensitive phase transformation of PNIPAM, the permeability of the modified membranes showed robust anion and thermal dual-responsive behaviors. In addition, the response temperature of the membranes could be adjusted precisely from 30 to 55 degrees C by anion exchange, which was attributed to the cooperative interaction of the PIL and PNIPAM. The switchable response temperature and the dual-responsive performances of the membranes were demonstrated by measuring the water fluxes under various conditions. The results indicated that the membrane permeabilities increased when exchanging the counteranions (CAs) from hydrophilic to hydrophobic ones; the thermal response behaviors were also obvious, and the sensitivity increased when increasing the hydrophobicity of the CA (the fluxes could be adjusted from 0 to 3800 mL/m2 mmHgh by controlling the temperature and CAs). At last, filtration tests were designed with the membranes, and the results indicated that by controlling the temperature and/or CA species, three different poly(ethylene glycol) molecules could be easily separated according to their molecule sizes in a single step. PMID- 30277385 TI - Fluorinated Prolines as Conformational Tools and Reporters for Peptide and Protein Chemistry. AB - Amide bonds at the proline nitrogen are particularly susceptible to rotation, affording cis and trans isomers. Installation of a stereochemically defined electron-withdrawing fluorine atom or fluorinated groups has the power to influence the cis- trans conformational preferences of the amide bond in X-(F)Pro (where X = any other amino acid). Advantageously, this also provides a sensitive reporter for 19F nuclear magnetic resonance (NMR) studies of protein conformation, interactions, and dynamics. We deliberately use the term "fluorinated prolines" as an all-encompassing term to describe proline analogues containing one or more fluorine atoms and to avoid confusion with the more well known 4-fluoroprolines. This review presents a critical discussion of the growing repertoire of fluorinated prolines that have been described and, importantly, provides a comparison of their uses and relative influence on amide-bond conformation and discusses the significant potential of using 19F NMR as a tool to probe conformational changes in polypeptides. PMID- 30277386 TI - Silica-Encapsulated DNA-Based Tracers for Aquifer Characterization. AB - Environmental tracing is a direct way to characterize aquifers, evaluate the solute transfer parameter in underground reservoirs, and track contamination. By performing multitracer tests, and translating the tracer breakthrough times into tomographic maps, key parameters such as a reservoir's effective porosity and permeability field may be obtained. DNA, with its modular design, allows the generation of a virtually unlimited number of distinguishable tracers. To overcome the insufficient DNA stability due to microbial activity, heat, and chemical stress, we present a method to encapsulated DNA into silica with control over the particle size. The reliability of DNA quantification is improved by the sample preservation with NaN3 and particle redispersion strategies. In both sand column and unconsolidated aquifer experiments, DNA-based particle tracers exhibited slightly earlier and sharper breakthrough than the traditional solute tracer uranine. The reason behind this observation is the size exclusion effect, whereby larger tracer particles are excluded from small pores, and are therefore transported with higher average velocity, which is pore size-dependent. Identical surface properties, and thus flow behavior, makes the new material an attractive tracer to characterize sandy groundwater reservoirs or to track multiple sources of contaminants with high spatial resolution. PMID- 30277387 TI - Copper Sulfide-Based Plasmonic Photothermal Membrane for High-Efficiency Solar Vapor Generation. AB - Solar vapor generation has attracted tremendous attention as one of the most efficient ways of utilizing solar energy. It is highly desirable to develop low cost, eco-friendly, and high-efficiency solar absorbers for practical applications of solar vapor generation. Herein, a three-dimensional plasmonic covellite CuS hierarchical nanostructure has been synthesized as the light absorbing material via a facile one-pot hydrothermal method for structurally integrated solar absorbers with microporous poly(vinylidene fluoride) membrane (PVDFM) as the supporting material. A broadband and highly efficient light absorption has been achieved in the wavelength of 300-2500 nm, along with high water evaporation efficiencies of 90.4 +/- 1.1 and 93.3 +/- 2.0% under 1 and 4 sun irradiation, respectively. Meanwhile, stable performance has been demonstrated for over 20 consecutive runs without much performance degradation. To the best of our knowledge, this is the highest performance among the copper sulfide-based solar absorbers. With the additional features of low-cost and convenient fabrication, this plasmonic solar absorber exhibits a tremendous potential for practical solar vapor generation. PMID- 30277388 TI - Control of Size and Composition of Colloidal Nanocrystals of Manganese Oxide. AB - A comprehensive study on the effects of experimental parameters on the composition and size of manganese oxide nanocrystals was completed using colloidal chemistry. The reactions studied involved the thermolysis of Mn2+ acetate and Mn3+ acetylacetonate in oleylamine. Temperature was found to be the dominant factor affecting the composition and size of the products. Reactions completed below 200 degrees C favored the formation of nanocrystals smaller than 20 nm, with the presence of even impurity amounts of oxidizing agents leading to the formation of Mn3O4. Nanocrystals of MnO could only be synthesized below 200 degrees C if Mn2+ acetate was used, and the reaction was carefully controlled to have no O2 and H2O contamination. In turn, particle growth was rapid above this temperature. In this case, regardless of the oxidizing agents used or oxidation state of the Mn precursor, nanocrystals of MnO formed after annealing for at least 1 h at temperatures higher than 200 degrees C. This finding suggests the role of oleylamine as solvent, surfactant, and reducing agent at sufficiently high annealing temperatures. These results increase the understanding of redox stability of manganese during the colloidal synthesis of semiconductor metal oxide nanocrystals. PMID- 30277389 TI - Graphene Oxide Membranes with Conical Nanochannels for Ultrafast Water Transport. AB - Membrane-based separations have been increasingly utilized to address global energy crisis and water scarcity. However, the separation efficiency often suffers from the trade-off between membrane permeability and selectivity. Although great efforts have been devoted, a membrane with both high permeability and high selectivity remains a distant prospect. Inspired by the hourglass structure and ultrafast water transport in aquaporins, we propose a novel approach to fabricating membranes with conical nanochannels to reduce the mass transfer resistance and to introduce Laplace pressure as the internal driving force, which successfully breaks the permeability/selectivity trade-off. First, sulfonated polyaniline (SPANI) nanorods were in situ-synthesized and vertically aligned on sulfonated graphene oxide (SGO) nanosheets, forming SGO-SPANI X composites. Then, the graphene oxide (GO) membranes were fabricated by assembling SGO-SPANI X composites through pressure-assisted filtration, in which the SPANI nanorods would bend and flatten on the SGO nanosheets under low shear force, forming stripe arrays on SGO nanosheets. The tilted stripe arrays between the adjacent SGO nanosheets form the conical nanochannels inside GO membranes. The conical nanochannels significantly decreased the steric hindrance and enabled the generation of Laplace pressure as the internal driving force within membranes. Consequently, the resulting membranes exhibit an ultrahigh water permeability of 1222.77 L.m-2.h-1.bar-1 and high efficiency in dye removal from water with a rejection of 90.44% and permeability of 528 L.m-2.h-1.bar-1. PMID- 30277390 TI - Temperature-Dependent Nuclear Spin Relaxation Due to Paramagnetic Dopants Below 30 K: Relevance to DNP-Enhanced Magnetic Resonance Imaging. AB - Dynamic nuclear polarization (DNP) can increase nuclear magnetic resonance (NMR) signal strengths by factors of 100 or more at low temperatures. In magnetic resonance imaging (MRI), signal enhancements from DNP potentially lead to enhancements in image resolution. However, the paramagnetic dopants required for DNP also reduce nuclear spin relaxation times, producing signal losses that may cancel the signal enhancements from DNP. Here we investigate the dependence of 1H NMR relaxation times, including T1rho and T2, under conditions of Lee-Goldburg 1H 1H decoupling and pulsed spin locking, on temperature and dopant concentration in frozen solutions that contain the trinitroxide compound DOTOPA. We find that relaxation times become longer at temperatures below 10 K, where DOTOPA electron spins become strongly polarized at equilibrium in a 9.39 T magnetic field. We show that the dependences of relaxation times on temperature and DOTOPA concentration can be reproduced qualitatively (although not quantitatively) by detailed simulations of magnetic field fluctuations due to flip-flop transitions in a system of dipole-coupled electron spin magnetic moments. These results have implications for ongoing attempts to reach submicron resolution in inductively detected MRI at very low temperatures. PMID- 30277391 TI - Protein-Resistant Property of Egg White Ovomucin under Different pHs and Ionic Strengths. AB - Ovomucin is a mucin-type glycoprotein accounting for 3.5% (w/w) of total egg white proteins. The purpose of the study was to explore the potential of ovomucin as a protein-resistant material. Using bovine serum albumin (BSA) as a model protein, ovomucin decreased the fluorescence intensities of the adsorbed BSA from 10.90 +/- 2.18 to 0.67 +/- 0.75, indicating its protein-resistant property. To understand the underlying mechanism, pure repulsive forces between ovomucin and model proteins (e.g., BSA and ovomucin) at various pHs (2.0, 6.0, and 7.2) and ionic strengths (0.1, 10, and 150 mM NaCl) were measured using a surface forces apparatus. Further studies by using atomic force microscope imaging, zeta potential, and dynamic light scattering suggested that the protein-resistant property of ovomucin was mainly attributed to strong electrostatic and steric repulsions between protein layers. This work has demonstrated that ovomucin has antifouling potential with broad applications in the areas of food processing industry and biomedical implants.

AB - The catalytic efficiency of various amine-squaramides was tested in Michael/hemiketalization reactions of 4-hydroxycoumarines with two types of enones. Tertiary amine-squaramide organocatalysts afforded the best results regarding both activity and enantioselectivity when beta,gamma-unsaturated alpha ketoesters were used as the Michael acceptors (yields up to 98%, enantioselectivities up to 90% ee). On the other hand, the primary amine squaramides are the best choice for related reactions of 4-hydroxycoumarins with enones. The corresponding pyrano[3,2- c]chromen-5-on products were obtained in high enantiomeric purities (up to 96%). The Michael addition of 4-hydroxycoumarin to 4-phenylbut-3-en-2-on directly produced chiral anticoagulant drug ( S) warfarin in 92% ee when green solvent 2-MeTHF and catalyst ( S, S)-C8 were used. Moreover, an enantiomeric catalyst ( R, R)-C8 gave ( R)-warfarin in >99% ee. PMID- 30277393 TI - The Effect of Electrostatic Interactions on the Folding Kinetics of a 3-alpha Helical Bundle Protein Family. AB - The trio of protein segment repeats called spectrins diverges by more than 2 orders of magnitude in their folding and unfolding rates, despite having very similar stabilities and almost coincidental topologies. Experimental studies revealed that the mutation of five particular residues dramatically alters the kinetic rates in the slow folders, making them similar to the rates of the fast folder. This is considered to be an exceptional behavior which seems in principle to challenge the current understanding of the protein folding process. In this work, we analyze this scenario, using a simplified computational model, combined with state-of-the-art kinetic analysis techniques. Our model faithfully separates the kinetics of the fast and slow folders and captures the effect of the five mutations. We show that the inclusion of electrostatics in the model is necessary to explain the experimental findings. PMID- 30277394 TI - DNA Solvation Dynamics. AB - Experiments have revealed that DNA solvation dynamics is characterized by multiple time scales ranging from a few picoseconds to a few hundred nanoseconds and in some cases even up to several microseconds. The last part of decay is not only slow but can also be described by a power law (PL). The microscopic origin of this PL is yet to be clearly established. Here we present a theoretical study employing multiple approaches from time dependent statistical mechanics and computer simulations. The present study shows that water dynamics may not account for the slow PL decay because the longest time scales describing water dynamics could be at most of the order of 100 ps. We find that the DNA solvation dynamics is complex, due to multiple different contributions to solvation energy. Our investigations also show that the primary candidates for this exotic nature of solvation dynamics are the response of the counterions and ions of the buffer solution. We first employ the well-known Oosawa model of polyelectrolyte solution that includes effects of counterion fluctuations to construct a frequency dependent dielectric function. We use it in the continuum model of Bagchi, Fleming, and Oxtoby (BOF). We find that it fails to explain the slow PL decay of DNA solvation dynamics. We then extend the Oosawa model by employing the continuous time random walk technique developed by Scher, Montroll and Lax. We find that this approach could explain the long time PL decay, in terms of the collective response of the counterions. To check the nature of random walk of counterions along the phosphate backbone, we carry out atomistic molecular dynamics (MD) simulations with a long (38 base pair) DNA. We indeed find frequent occurrence of random walk of tagged counterions along the phosphate backbone. We next propose a generalized random walk model for counterion hopping on phosphate backbone (observed in our MD simulations) and carry out kinetic Monte Carlo simulations to show that the nonexponential contribution to solvation dynamics can indeed come from dynamics of such ions. We also employ a mode coupling theory (MCT) analysis to understand the slow relaxation that can originate from ions in solution due to the use of the buffer. Explicit evaluation suggests that buffer ion contribution could explain a logarithmic time dependence in the nanosecond time scale but not a power law. To further understand the nonexponentiality of solvation dynamics at relatively shorter times (less than 100 ps) we carry out atomistic MD simulations with explicit water molecules. Log-normal distributions of relaxation times of water dynamics inside the grooves may be responsible for the initial multiexponential decay of solvation dynamics. We find that the observed faster solvation of groove bound probe than that of the intercalated probe could arise from the self-motion of the probe. PMID- 30277395 TI - Identification and Characterization of DNA Aptamers Specific for Phosphorylation Epitopes of Tau Protein. AB - Tau proteins are proteins that stabilize microtubules, but their hyperphosphorylation can result in the formation of protein aggregates and, over time, neurodegeneration. This phenomenon, termed tauopathy, is pathologically involved in several neurodegenerative disorders. DNA aptamers are single-stranded oligonucleotides capable of specific binding to target molecules. Using tau epitopes predisposed for phosphorylation, we identified six distinct aptamers that bind to tau at two phosphorylatable epitopes (Thr-231 and Ser-202) and to full-length Tau441 proteins with nanomolar affinity. In addition, several of these aptamers also inhibit tau phosphorylation (IT4, IT5, IT6) and tau oligomerization (IT3, IT4, IT5, IT6). This is the first report to identify tau epitope-specific aptamers. Such tau aptamers can be used to detect tau in biofluids and uncover the mechanism of tauopathy. They can be further developed into novel therapeutic agents in mitigating tauopathy-associated neurodegenerative disorders. PMID- 30277396 TI - Atomic-Level Description of Protein Folding inside the GroEL Cavity. AB - Chaperonins (ubiquitous facilitators of protein folding) sequester misfolded proteins within an internal cavity, thus preventing protein aggregation during the process of refolding. GroEL, a tetradecameric bacterial chaperonin, is one of the most studied chaperonins, but the role of the internal cavity in the refolding process is still unclear. It has been suggested that rather than simply isolating proteins while they refold, the GroEL cavity actively promotes protein folding. A detailed characterization of the folding dynamics and thermodynamics of protein substrates encapsulated within the cavity, however, has been difficult to obtain by experimental means, due to the system's complexity and the many steps in the folding cycle. Here, we examine the influence of the GroEL cavity on protein folding based on the results of unbiased, atomistic molecular dynamics simulations. We first verified that the computational setup, which uses a recently developed state-of-the-art force field that more accurately reproduces the aggregation propensity of unfolded states, could recapitulate the essential structural dynamics of GroEL. In these simulations, the GroEL tetradecamer was highly dynamic, transitioning among states corresponding to most of the structures that have been observed experimentally. We then simulated a small, unfolded protein both in the GroEL cavity and in bulk solution and compared the protein's folding process within these two environments. Inside the GroEL cavity, the unfolded protein interacted strongly with the disordered residues in GroEL's C-terminal tails. These interactions stabilized the protein's unfolded states relative to its compact states and increased the roughness of its folding free energy surface, resulting in slower folding compared to the rate in solution. For larger proteins, which are more typical GroEL substrates, we speculate that these interactions may allow substrates to more quickly escape kinetic traps associated with compact, misfolded states, thereby actively promoting folding.

AB - The protein-polyphenol layer by layer (LbL) assembled polymer composite microcapsule is a considerable delivery system that can be used to improve the bioactive stability and effectiveness of natural compounds in various applications. In the present study, three kinds of polyphenols were loaded in the sequence of (-)-epigallocatechin gallate (EGCG), 3,4- O-dicaffeoylquinic acid (3,4-diCQA), and tannin acid (TA) to prepare a BSA-polyphenol LbL membrane. The composition of IgG-(BSA-EGCG/3,4-diCQA/TA) n microcapsules and their stability and releasing ability in the gastrointestinal tract were evaluated. In addition, by binding of these three kinds of polyphenols to BSA, the thermal denaturation temperature and ordered secondary structure of the BSA-polyphenol microcapsules were increased, and the time of scavenging activity on 2,2'-azinobis(3 ethylbenzothiazolin-6-sulfonic acid) free radicals was significantly prolonged. These findings suggest that (BSA-EGCG/3,4-diCQA/TA) n microcapsules can not only protect IgG in food processing and stomach digestion but also release it in the small intestinal tract for bioactive delivery.

AB - Biotinylated hepta-, nona- and undeca-alpha-(1 -> 3)-d-glucosides representing long oligosaccharides of alpha-(1 -> 3)-d-glucan, one of the major components of the cell walls of the fungal pathogen Aspergillus fumigatus, were synthesized for the first time via a blockwise strategy. Convergent assembly of the alpha-(1 -> 3)-d-glucan chains was achieved by glycosylation with oligoglucoside derivatives bearing 6- O-benzoyl groups. Those groups are capable of remote alpha stereocontrolling participation, making them efficient alpha-directing tools even in the case of large glycosyl donors. Synthetic biotinylated oligoglucosides (and biotinylated derivatives of previously synthesized tri- and penta-alpha-(1 -> 3) d-glucosides) loaded on streptavidin microtiter plates were shown to be better recognized by anti-alpha-(1 -> 3)-glucan human polyclonal antibodies and to induce higher cytokine responses upon stimulation of human peripheral blood mononuclear cells than their natural counterpart, alpha-(1 -> 3)-d-glucan, immobilized on a conventional microtiter plate. Attachment of the synthetic oligosaccharides equipped with a hydrophilic spacer via the streptavidin-biotin pair allows better spatial presentation and control of the loading compared to the random sorption of natural alpha-(1 -> 3)-glucan. Increase of oligoglucoside length results in their better recognition and enhancement of cytokine production. Thus, using synthetic alpha-(1 -> 3)-glucan oligosaccharides, we developed an assay for the host immune response that is more sensitive than the assay based on native alpha-(1 -> 3)-glucan. PMID- 30277399 TI - Probing Protein Dynamics Using Multifield Variable Temperature NMR Relaxation and Molecular Dynamics Simulation. AB - Understanding the interplay between protein function and dynamics is currently one of the fundamental challenges of physical biology. Recently, a method using variable temperature solid-state nuclear magnetic resonance relaxation measurements has been proposed for the simultaneous measurement of 12 different activation energies reporting on distinct dynamic modes in the protein GB1. Here, we extend this approach to measure relaxation at multiple magnetic field strengths, allowing us to better constrain the motional models and to simultaneously evaluate the robustness and physical basis of the method. The data reveal backbone and side-chain motions, exhibiting low- and high-energy modes with temperature coefficients around 5 and 25 kJ.mol-1. The results are compared to variable temperature molecular dynamics simulation of the crystal lattice, providing further support for the interpretation of the experimental data in terms of molecular motion.

AB - Mechanistic evaluations and comparison of two important aerobic catalytic oxidation processes, aerobic copper catalysis and photoredox catalysis, are performed. Interesting and distinct catalytic behaviors were observed for a common reaction of iodolactonization of alkenoic acids. Namely, the aerobic copper catalysis requires the formation of a copper carboxylate, whereas the aerobic photoredox catalysis requires the addition of proton sources to proceed to completion. Furthermore, the iodolactone products obtained from these catalytic processes are extensively derivatized to a number of functionalized lactones, including aryl lactones generated from the nickel-catalyzed reductive coupling with aryl halides.

PMID- 30277405 TI - A Necessary Trade-off for Semiclassical Electrodynamics: Accurate Short-Range Coulomb Interactions versus the Enforcement of Causality? AB - We investigate two key representative semiclassical approaches for propagating resonant energy transfer (RET) between a pair of electronic two-level systems (donor and acceptor) with coupled Maxwell-Liouville equations. On the one hand, when the electromagnetic (EM) field is treated classically and Coulomb interactions are treated quantum-mechanically, we find that a quantum-classical mismatch leads to a violation of causality, i.e., the acceptor can be excited before the retarded EM field arrives. On the other hand, if we invoke a classical intermolecular Coulomb operator, we find that the energy transfer in the near field loses quantitative accuracy compared with Forster theory, even though causality is strictly obeyed. Thus, our work raises a fundamental paradox when choosing a semiclassical electrodynamics algorithm. Namely, which is more important: Accurate short-range interactions or long-range causality? Apparently, one cannot have one's cake and eat it too. PMID- 30277406 TI - An Interrupted Schmidt Reaction: C-C Bond Formation Arising from Nitrilium Ion Capture.

AB - Cardiovascular magnetic resonance (CMR) has an emerging role in aortic valve disease evaluation (AVD), becoming an all-in-one technique. CMR evaluation of the anatomy and flow through the aortic valve has a higher reproducibility than echocardiography. Its unique ability of in-vivo myocardial tissue characterization, significantly improves the risk stratification and management of patients. In addition, CMR is equivalent to cardiac computed tomography angiography for trans-aortic valvular implantation and surgical aortic valve replacement planning; on the other hand, its role in the evaluation of ventricular function improving and post-treatment complications is undisputed.

PMID- 30277409 TI - The risk for opportunistic infections in inflammatory bowel disease with biologics: an update. AB - INTRODUCTION: Crohn's disease and Ulcerative Colitis are forms of inflammatory bowel disease (IBD), chronic diseases treated with medical and surgical therapy. Patients with IBD are treated with potent immunomodulatory agents, leading to immunosuppression, and the potential for opportunistic infections. In 2014, the ECCO guidelines were released to guide the prevention, diagnosis and treatment of a variety of these opportunistic infections. Since 2014, there have been a number of new agents released as well as a significant expansion in our knowledge of the safety profile of IBD medications. In this paper we review the literature after 2014 regarding opportunistic infections and updates on safety data. Areas covered: We review updates in immunomodulatory therapies for IBD and opportunistic infections since the 2014 ECCO guidelines were published. Expert commentary: The prevention, diagnosis and treatment of opportunistic infections continues to evolve, as new drugs are approved, and the use of a combination of biologic agents are considered for therapy in clinical trials. What causes some patients to fail to respond to vaccination, or for others to develop severe infections, remains unclear. Improved risk stratification for opportunistic infections in IBD patients and updated ECCO 2014 guidelines would be of significant benefit.

AB - The Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS) is a self-report instrument assessing the satisfaction and frustration of the three basic psychological needs of autonomy, competence, and relatedness defined by self-determination theory. The aim of this study was to examine the dimensionality, the predictive validity, and the measurement invariance across different age groups of the Italian version of the BPNSFS. The participants were 2,204 Italian adolescents and young adults (41% males) from 14 to 28 years old (M age = 20.23, SD = 4.25). The invariance across age demonstrated adequate equivalence of the 6-factor model of scales across adolescents (14-18 years) and young adults (20-24 years), showing general homogeneity with respect to the constructs measured in the Italian context. Results of this study suggest that the satisfaction and frustration subscales for each need might be treated separately, because they might have unique effects that should be explored. For this reason, the BPNSFS could be a useful instrument in the counseling context because it can be easily used by operators both for assessment and for evaluation of the effects and results of counseling intervention.

AB - BACKGROUND: The evolution of healthcare in Ukraine has been impacted by a number of factors, including years of communist control followed by the birth of an emerging democracy and most recently, conflict in the eastern part of the country. Rehabilitation is an aspect of Ukraine's healthcare system that is still heavily influenced by the Soviet-era mentality of perfectionism. METHODS: This article presents the results of a qualitative research study that undertook 13 key informant interviews to answer the question of what can be learned from the perspectives of individuals in Ukraine or with experience working in Ukraine with respect to developing and implementing appropriate rehabilitation that is inclusive and targets health equity. RESULTS: Key themes that informants determined will affect the future of rehabilitation in Ukraine include the current health care structure, the culture surrounding disability, international and domestic sources of involvement, and a revised curriculum for new and existing rehabilitation professionals. CONCLUSIONS: The input from these individuals, supported by evidence from the literature, provides a foundational understanding of the currently fragmented rehabilitation system in Ukraine and the factors that professionals prioritize as integral components of an infrastructure that supports rehabilitation in the twenty-first century. Implications for Rehabilitation While the recent conflict in Eastern Ukraine has served as a lightning rod to shed light on the lack of resources allocated toward disability and chronic care in the region, rehabilitation is also lacking in the general population, requiring a response that addresses the unique needs of a population of over 44 million individuals. Alongside a curriculum that complies with international accreditation standards, an influx of job and career opportunities developed by the government is needed to encourage individuals to work in the rehabilitation sector. A nation-wide strategy must be developed to disseminate knowledge about disability and rehabilitation in order to begin to address the issues of social exclusion and stigma associated with disability in many post-Soviet countries.

AB - After a "silence" period for decades, a great body of new information has become available about the pathogenesis, diagnosis and treatment of gout. New data on purine metabolism and urate transporters have been published. It has become evident that gout is an autoinflammatory disease involving the inflammasome and interleukin-1. With respect to diagnosis, microscopic evaluation of the urate crystal is still the gold standard, however, sensitive imaging techniques (ultrasound, modern computed tomography methods) are able to visualize crystal deposition and tophus formation. Tophus size may also be monitored over time. We see a renaissance of non-pharmacological, lifestyle-related treatment modalities. Pharmacotherapy includes the resolution of attacks and urate-lowering maintenance therapy. In 2016, two recent series of recommendations have been published. Treat to-target therapy aiming at urate levels <=360 MUmol/l is crucial. Urate-lowering therapy includes xanthine oxidase inhibitors (allopurinol, febuxostat). However, a number of novel compounds (urate transporter inhibitors, recombinant uricase, interleukin-1 inhibitors) are under development or before introduction to gout treatment. Comorbidites should be considered throughout the follow-up of gout patients. Orv Hetil. 2018; 159(40): 1625-1636.

AB - Genome-wide association studies (GWAS) using population-based designs have identified many genetic loci, at which common variants can influence the risk of developing the sporadic colon cancers. These are single nucleotide polymorphisms (SNPs) located on different chromosomes, close to genes involved in cancer developing process, and the SNPs modify their functions, and as a consequence the cancer risk is increased. Our aim was to provide frequency distributions data of variable (risk) allele of six independent SNPs in patients with colorectal cancers and in control Hungarian population, predicting the increased risk effect of sequence variant of SNPs. We also investigated the frequency distribution of tumor localization between right or left half of large bowel as well as the RAS mutation status. 47 non-tumorous patients and 47 patients with colorectal cancer were given oral mucosa cells or blood samples for SNP analysis. After DNA isolation, an LC480 (Roche) type PCR instrument, asymmetric LATE PCR method and melting point analysis were used for detection of sequence variations, by the assistance of two SNP specific primers, unlabeled specific probe and intercalating fluorescent dye. Genomic frequency distribution of variable alleles of SNPs predisposed to tumor development have been investigated in colorectal cancer carrier patients and the results have been compared with the same allele frequency distribution data obtained from the non-tumorous control patients and from CEU population stored in SNPnexus data base. The homozygous risk alleles of SNPs showed a 1.5-2.3-time increase in colorectal cancer carrier patients then in control and CEU patients, but the heterozygous risk allele distribution was identical in tumorous and control population. The frequency distribution of homozygous risk alleles of six SNPs was also investigated in the same time and some patients. Among 47 patients with colorectal cancer, in 3 patients carrying 3 SNPs with homozygous risk alleles, in additional 5 tumor samples two and 24 samples contain only one SNP's homozygous risk alleles, and in 15 patients, SNPs with homozygous risk alleles do not occur. In 47 control patients, only 3 samples contain two SNPs with homozygous risk alleles and 17 samples contain only one SNP with homozygous risk alleles. Significant differences of the tumorous and the control population can be seen detected. NRAS mutation was not found. Our results showed a real increased risk effect of several newly recognized low-penetrance colorectal cancer susceptibility genetic variants by influence of the regulation of neighboring genes, however, the degree of cancer risk is individual, and influenced by others environmental factors, such as dietary factors.

AB - INTRODUCTION AND AIM: To determine whether the continuous use of gel-type denture adhesives influence the unstimulated whole saliva, the palatal and labial saliva flow rates, and to assess the possible changes of subjective orofacial sicca symptoms. METHOD: 28 maxillary complete denture wearing patients (average age: 70 +/- 10 years) were investigated. A gel-type denture adhesive was administered to the patients for regular use during the 3 weeks of examination. A questionnaire of 16 questions was used to evaluate subjective orofacial sicca symptoms. Unstimulated whole saliva was determined by the spitting method, palatal and labial saliva flow rates were measured by the Periotron(r) device with filter paper discs at the initial, first, second and third weeks. STATISTICAL ANALYSIS: The following tests were used: subjective values - chi2-test; flow rates - ANOVA, paired Student's t-test. RESULTS: According to the questionnaire, the ratio or severity of xerostomia did not change. A significant increase in the subjective feeling of "saliva thickness" could be detected (p = 0.027), but the other subjective parameters remained unchanged. Palatal saliva flow rates decreased significantly by week 3 (week 0: 4.21 +/- 3.96 ul/cm2/min; week 3: 2.21 +/- 2.30 ul/cm2/min; p = 0.024). On the other hand, there was no significant change in the unstimulated whole saliva (week 0: 0.37 +/- 0.36 ml/min; week 3: 0.39 +/- 0.35 ml/min) and labial saliva (week 0: 3.99 +/- 3.75 ul/cm2/min; week 3: 2.58 +/- 3.39 ul/cm2/min) flow rates. CONCLUSIONS: The regular use of denture adhesives did not influence xerostomia and the majority of subjective orofacial sicca symptoms, but may cause a subjective feeling of "increased saliva thickness" and reduce palatal minor salivary gland flow rates among complete maxillary denture wearers.

AB - We report here a novel alpha1-globin chain variant, Hb Hubei [alpha114(GH2)Pro >His, HBA1: c.344C>A], in a Chinese individual. The proband, a 28-year-old Chinese female, was discovered following routine Hb A1c analysis using cation exchange high performance liquid chromatography (HPLC). Sanger sequencing revealed a novel missense mutation, HBA1: c.344C>A (CCC>CAC), in exon 2 of the alpha1-globin gene. The mutation caused a transition of proline to histidine at position alpha114(GH2) on the alpha1-globin chain. This new variant was named Hb Hubei after the geographic origin of the proband.

AB - This report describes the results of a study on the antiproliferative activity of the morpholine-based ligand 1,3-bis(1-morpholinothiocarbonyl)benzene (HL) and its nickel(II) complex (NiL) against human breast cancer cells (MCF-7), colon carcinoma cells (C26) and normal fibroblast NIH-3T3 cells. NiL showed better cytotoxicity on both cancerous cells relative to normal cells in vitro with the highest selective index of 2.22 in MCF-7 cells. The interaction of both compounds with calf thymus DNA (CT DNA) and bovine serum albumin (BSA) was studied using various spectroscopic techniques and analytical methods such as UV-vis titrations, thermal denaturation, circular dichroism, competitive fluorescent intercalator displacement assays, as well as molecular modeling. The fluorescence intensity of the probe molecule increases clearly when HL and NiL are added to the methylene blue (MB)-DNA system. Furthermore, the binding of HL and NiL quenches the BSA fluorescence, revealing a 1:1 interaction with a binding constant of about 105 M-1. PMID- 30277420 TI - Distinct Effects of Repeated-Sprint Training in Normobaric Hypoxia and beta Alanine Supplementation. AB - OBJECTIVE: The present study evaluated the effects of repeated-sprint training in normobaric hypoxia and beta-alanine supplementation (BA) on aerobic and anaerobic performance in recreationally active men. METHODS: Participants were randomly assigned to one of the following groups: normoxia/beta-alanine (NB, n = 11), normoxia/placebo (NP, n = 8), normobaric hypoxia/beta-alanine (HB, n = 10) and normobaric hypoxia/placebo (HP, n = 9). All participants completed 8 training sessions over 4 weeks on a cycle ergometer either in normobaric hypoxia (oxygen fraction: FiO2 = 14.2%) or normoxia (FiO2 = 20.9%). Participants were instructed to consume a daily dosage of 6.4 g of BA or placebo. Changes in performance in a graded exercise test, repeated-sprint test (RST), and 3-minute all-out test (3MT) were examined before and after training and supplementation. RESULTS: No between group differences were observed for training volume or supplementation compliance. Anthropometric and hematological measures remained unchanged before and after intervention in all groups. A main effect of training condition was shown for oxygen consumption and power output at respiratory compensation point, average power output during the last sprint of the RST, heart rate recovery following the RST, and total work during the 3MT. These measures in the normobaric hypoxia groups were significantly (p < 0.05) higher than the normoxia groups, except for the heart rate recovery following the RST. A main effect of supplement was detected in anaerobic working capacity, with postintervention values in the BA groups being significantly (p < 0.05) higher than the placebo groups. CONCLUSIONS: Repeated-sprint training in hypoxia improved aerobic performance, exercise tolerance, cardiovascular recovery, and overall working capacity, while BA maintained the anaerobic working capacity. However, BA did not provide additional benefits with respect to attenuating fatigue or enhancing repeated-sprint performance.

AB - AIM: Sol-gel is a suitable and advantageous method to synthesize mixed oxide nanomaterials with unique physicochemical and biological properties. MATERIALS & METHODS: In this work, TiO2-SiO2 nanopowders cogeled with platinum acetylacetonate were developed and studied in the perspective of nanomedicine. The physicochemical properties of the Pt/TiO2-SiO2 nanopowders, named NanoRa2-Pt, were evaluated in detail by means of complementary spectroscopic and microscopic tools. The nanopowder's biocatalytic efficiency in wound healing was evaluated in a Type I diabetes animal model. RESULTS: These are TiO2-SiO2 submicron mesoporous particles with variable size and shape containing ultra-small platinum nanoparticles with catalytic properties. CONCLUSION: The use of NanoRa2-Pt catalyzes the natural healing processes with a faster remodeling stage. These sols, which we call nanobiocatalysts, belong to an emerging and very promising research field known as catalytic nanomedicine. PMID- 30277423 TI - Critical review of renal tubule karyomegaly in non-clinical safety evaluation studies and its significance for human risk assessment. AB - : Scientific databases were searched for terms applicable to karyomegaly in renal tubules of laboratory animals used in preclinical safety evaluation studies, and in humans. Renal tubule karyomegaly was more frequently reported in the rat in response to chemical exposure compared to other laboratory animal species. Renal tubule karyomegaly also occurred in the mouse in response to chemical insult, but much less commonly than in the rat. This nuclear lesion was recorded infrequently for hamster, dog, guinea pig, rabbit, pig, and non-human primate. Most instances of renal karyomegaly reported in humans represented cases of the genetic syndrome, karyomegalic interstitial nephritis, known to be caused by a mutation in the FAN1 gene. Human reports of karyomegaly in the kidney associated with chemical exposure are rare, and linked mainly to chemotherapeutic or antiviral therapies. The rat appears to be highly predisposed to developing karyomegaly as a renal response on exposure to diverse chemical agents, but karyomegaly in the rat is not consistently associated with renal tubule tumor development. Because of this inconsistency, renal tubule karyomegaly is an inaccurate predictor of renal tubule neoplasia, and there is no evidence that karyomegalic cells are involved in tumor development as a form of preneoplasia. A chemically induced karyomegalic response in the rat does not necessarily predict a similar alteration in human kidneys. Because modest nuclear enlargement of kidney tubule cells can occur as physiological or functional responses, it is recommended that the threshold for diagnosing renal tubule karyomegaly in animal studies should be accepted as at least four times normal nuclear size or larger.

AB - BACKGROUND: Caregivers are often apprehensive about treating their child's atopic dermatitis with a topical corticosteroid. Typical concerns include anxiety regarding side effects and the perceived burden of treatment. The perception of burden may be modifiable through anchoring. OBJECTIVE: To evaluate caregivers' willingness to treat their child's atopic dermatitis with a topical corticosteroid once-daily if initially anchored to the idea of a four-times-daily treatment regimen. METHODS: A prospective survey study was performed in 100 caregivers of children with atopic dermatitis. Scores were treated as ordinal data and evaluated using the Mann-Whitney U test and chi-squared test. RESULTS: Of the 100 recruited participants, 97 were eligible and returned completed surveys. Subjects anchored to a four-times-daily treatment regimen were more willing to treat their child's atopic dermatitis once-daily (mean, 8.7) than those not anchored (mean, 7.9), however the difference between these groups was not statistically significant (P = 0.173). CONCLUSIONS: Caregivers reported being generally quite willing to apply topical corticosteroids once-daily. Anchoring was associated with a slightly higher score, though it was not statistically significant. For most patients with atopic dermatitis, anchoring may not be helpful, but for patients whose main barrier is perceived burdensomeness of treatment, anchoring may be of some benefit. PMID- 30277425 TI - The long non-coding RNA MALAT1 is increased in renal ischemia-reperfusion injury and inhibits hypoxia-induced inflammation. AB - BACKGROUND: To investigate the expression of long non-coding RNA metastasis associated lung adenocarcinoma transcript 1 (MALAT1) in renal ischemia reperfusion injury and explore its role in acute kidney injury. METHODS: 18 mice were randomly divided into a sham operation group (Sham) and an ischemia reperfusion group (IR) in which animals were sacrificed at 6 h or 12 h after surgery. The kidneys were harvested to measure the expression of MALAT1 mRNA. HK2 cells were treated with cobalt chloride (CoCl2) to mimic hypoxia or transfected with siRNA to knockdown MALAT1 before CoCl2 treatment. After that, MALAT1 was analyzed by RT-PCR (reverse transcription-polymerase chain reaction). HIF-1alpha (hypoxia-inducible factor-1 alpha) and NF-kappaB (nuclear factor-kappa B) was measured by Western blot. The concentrations of IL-6 (interleukin-6) and TNF alpha (tumor necrosis factor-alpha) in the media were detected by ELISA (enzyme linked immunosorbent assay). RESULTS: The expression of MALAT1 in the IR (6 h/12 h) group was significantly higher than that in the sham group. In HK2 cells, MALAT1 was significantly increased at 1 h, 3 h, and 6 h after CoCl2 treatment but had reduced to the basal level at 12 h and 24 h. Knockdown of MALAT1 by siRNA significantly up-regulated the expression of HIF-1alpha and NF-kappaB proteins in CoCl2-treated HK2 cells. In addition, the concentrations of IL-6 and TNF-alpha were increased by MALAT1 siRNA transfection in CoCl2-treated HK2 cells. CONCLUSION: The expression of MALAT1 is increased in renal ischemia-reperfusion injury. It is likely that MALAT1 inhibits the hypoxia-induced inflammatory response through the NF-kappaB pathway. PMID- 30277426 TI - Serum heme oxygenase 1 (HO-1), soluble FMS like tyrosine kinase (sFlt-1) level, and neonatal outcome in early onset, late onset preeclampsia, and normal pregnancy. AB - OBJECTIVE: To compare the level of serum heme oxygenase 1 (HO-1), soluble FMS like tyrosine kinase (sFlt-1), and neonatal outcome in early onset preeclampsia (EO-PE), late onset preeclampsia (LO-PE), and normal pregnancy (NP). METHODS: In this prospective observational case control study, HO-1 and sFlt-1 levels were measured in blood samples within 24 h of hospital admission. Preeclampsia cases were divided into two groups based on gestational age at delivery: EO-PE (<34 weeks) and LO-PE (>=34 weeks). A total of 45 patients were involved in this study. RESULT: Maternal serum level of sFlt-1 was higher in EO-PE than LO-PE and NP groups (mean +/- SD; 14.50 +/- 17.12 ng/ml vs 5.20 +/- 6.69 ng/ml vs 2.72 +/- 1.2 ng/ml [p = 0.020]. Maternal serum level of HO-1 was not different between EO PE, LO-PE, and NP groups (p = 0.681). Birthweights were significantly lower in the EO-PE group compared with the LO-PE and NP groups (1580 +/- 536 g vs 2635 +/- 578 g vs 3010 +/- 371 g [p = 0.000]). The rate of small for gestational age infant (26.7% vs 6.7% vs 0%; p = 0.046) and perinatal death (20% vs 0 vs 0; p = 0.037) was also significantly higher in EO-PE compared to LO-PE and NP. The maternal sFlt-1 level was negatively correlated with birthweight (p = 0.006; CC = -0.445). CONCLUSION: This study did not find a correlation between maternal HO-1 levels and sFlt-1 levels. Maternal serum sFLt-1 levels in preeclampsia were higher in EO-PE and were associated with a worse perinatal outcome. PMID- 30277427 TI - Prediction of Isocitrate Dehydrogenase Genotype in Brain Gliomas with MRI: Single Shell versus Multishell Diffusion Models. AB - Purpose The primary aim of this prospective observational study was to assess whether diffusion MRI metrics correlate with isocitrate dehydrogenase (IDH) status in grade II and III gliomas. A secondary aim was to investigate whether multishell acquisitions with advanced models such as neurite orientation dispersion and density imaging (NODDI) and diffusion kurtosis imaging offer greater diagnostic accuracy than diffusion-tensor imaging (DTI). Materials and Methods Diffusion MRI (b = 700 and 2000 sec/mm2) was performed preoperatively in 192 consecutive participants (113 male and 79 female participants; mean age, 46.18 years; age range, 14-77 years) with grade II (n = 62), grade III (n = 58), or grade IV (n = 72) gliomas. DTI, diffusion kurtosis imaging, and NODDI metrics were measured in regions with or without hyperintensity on diffusion MR images and compared among groups defined according to IDH genotype, 1p/19q codeletion status, and tumor grade by using Mann-Whitney tests. Results In grade II and III IDH wild-type gliomas, the maximum fractional anisotropy, kurtosis anisotropy, and restriction fraction were significantly higher and the minimum mean diffusivity was significantly lower than in IDH-mutant gliomas (P = .011, P = .002, P = .044, and P = .027, respectively); areas under the receiver operating characteristic curve ranged from 0.72 to 0.76. In IDH wild-type gliomas, no difference among grades II, III, and IV was found. In IDH-mutant gliomas, no difference between those with and those without 1p/19q loss was found. Conclusion Diffusion MRI metrics showed correlation with isocitrate dehydrogenase status in grade II and III gliomas. Advanced diffusion MRI models did not add diagnostic accuracy, supporting the inclusion of a single-shell diffusion-tensor imaging acquisition in brain tumor imaging protocols.

AB - Use of the hospitalist model has reduced the number of primary care physicians taking care of inpatients. Physician shortages in primary care has forced many healthcare systems to use locum physicians as part of their delivery system and physician practice plan. With value-based purchasing and new payment models, measuring quality and patient-satisfaction with the hospitalist model is important. Hospital administrators need to carefully monitor the use of locum hospitalists, especially around quality of care and clinical outcomes. PMID- 30277429 TI - The Neurodynamic Decision Variable in Human Multialternative Perceptual Choice. AB - The neural dynamics underpinning binary perceptual decisions and their transformation into actions are well studied, but real-world decisions typically offer more than two response alternatives. How does decision-related evidence accumulation dynamically influence multiple action representations in humans? The heightened conservatism required in multiple compared with binary choice scenarios suggests a mechanism that compensates for increased uncertainty when multiple choices are present by suppressing baseline activity. Here, we tracked action representations using corticospinal excitability during four- and two choice perceptual decisions and modeled them using a sequential sampling framework. We found that the predictions made by leaky competing accumulator models to accommodate multiple choices (i.e., reduced baseline activity to compensate increased uncertainty) were borne out by dynamic changes in human action representations. This suggests a direct and continuous influence of interacting evidence accumulators, each favoring a different decision alternative, on downstream corticospinal excitability during complex choice. PMID- 30277430 TI - The Sources of Dual-task Costs in Multisensory Working Memory Tasks. AB - We investigated the sources of dual-task costs arising in multisensory working memory (WM) tasks, where stimuli from different modalities have to be simultaneously maintained. Performance decrements relative to unimodal single task baselines have been attributed to a modality-unspecific central WM store, but such costs could also reflect increased demands on central executive processes involved in dual-task coordination. To compare these hypotheses, we asked participants to maintain two, three, or four visual items. Unimodal trials, where only this visual task was performed, and bimodal trials, where a concurrent tactile WM task required the additional maintenance of two tactile items, were randomly intermixed. We measured the visual and tactile contralateral delay activity (CDA/tCDA components) as markers of WM maintenance in visual and somatosensory areas. There were reliable dual-task costs, as visual CDA components were reduced in size and visual WM accuracy was impaired on bimodal relative to unimodal trials. However, these costs did not depend on visual load, which caused identical CDA modulations in unimodal and bimodal trials, suggesting that memorizing tactile items did not reduce the number of visual items that could be maintained. Visual load did not also affect tCDA amplitudes. These findings indicate that bimodal dual-task costs do not result from a competition between multisensory items for shared storage capacity. Instead, these costs reflect generic limitations of executive control mechanisms that coordinate multiple cognitive processes in dual tasks. Our results support hierarchical models of WM, where distributed maintenance processes with modality-specific capacity limitations are controlled by a central executive mechanism. PMID- 30277431 TI - Primary Interoceptive Cortex Activity during Simulated Experiences of the Body. AB - Studies of the classic exteroceptive sensory systems (e.g., vision, touch) consistently demonstrate that vividly imagining a sensory experience of the world simulating it-is associated with increased activity in the corresponding primary sensory cortex. We hypothesized, analogously, that simulating internal bodily sensations would be associated with increased neural activity in primary interoceptive cortex. An immersive, language-based mental imagery paradigm was used to test this hypothesis (e.g., imagine your heart pounding during a roller coaster ride, your face drenched in sweat during a workout). During two neuroimaging experiments, participants listened to vividly described situations and imagined "being there" in each scenario. In Study 1, we observed significantly heightened activity in primary interoceptive cortex (of dorsal posterior insula) during imagined experiences involving vivid internal sensations. This effect was specific to interoceptive simulation: It was not observed during a separate affect focus condition in Study 1 nor during an independent Study 2 that did not involve detailed simulation of internal sensations (instead involving simulation of other sensory experiences). These findings underscore the large-scale predictive architecture of the brain and reveal that words can be powerful drivers of bodily experiences.

AB - Courts routinely order defendants into treatment for substance use, requiring them to remain abstinent. A recent Massachusetts challenge to this practice claimed holding offenders responsible for behavior they could not control was unfair. Had the challenge been successful, it would have called into question the constitutionality of the successful drug court model, which is also applied in probation and parole settings. In rejecting the defendant's claims, the court made clear its skepticism that substance use disorders result in a complete loss of control over drug use and its reluctance to interfere with an established approach to problematic substance use.

AB - Purpose To investigate whether radiomic features at MRI improve survival prediction in patients with glioblastoma multiforme (GBM) when they are integrated with clinical and genetic profiles. Materials and Methods Data in patients with a diagnosis of GBM between December 2009 and January 2017 (217 patients) were retrospectively reviewed up to May 2017 and allocated to training and test sets (3:1 ratio). Radiomic features (n = 796) were extracted from multiparametric MRI. A random survival forest (RSF) model was trained with the radiomic features along with clinical and genetic profiles (O-6-methylguanine-DNA methyltransferase promoter methylation and isocitrate dehydrogenase 1 mutation statuses) to predict overall survival (OS) and progression-free survival (PFS). The RSF models were validated on the test set. The incremental values of radiomic features were evaluated by using the integrated area under the receiver operating characteristic curve (iAUC). Results The 217 patients had a mean age of 57.9 years, and there were 87 female patients (age range, 22-81 years) and 130 male patients (age range, 17-85 years). The median OS and PFS of patients were 352 days (range, 20-1809 days) and 264 days (range, 21-1809 days), respectively. The RSF radiomics models were successfully validated on the test set (iAUC, 0.652 [95% confidence interval {CI}, 0.524, 0.769] and 0.590 [95% CI: 0.502, 0.689] for OS and PFS, respectively). The addition of a radiomics model to clinical and genetic profiles improved survival prediction when compared with models containing clinical and genetic profiles alone (P = .04 and .03 for OS and PFS, respectively). Conclusion Radiomic MRI phenotyping can improve survival prediction when integrated with clinical and genetic profiles and thus has potential as a practical imaging biomarker.

PMID- 30277443 TI - Does Nonenhanced CT-based Quantification of Abdominal Aortic Calcification Outperform the Framingham Risk Score in Predicting Cardiovascular Events in Asymptomatic Adults? AB - Purpose To determine if abdominal aortic calcification (AAC) at CT predicts cardiovascular events independent of Framingham risk score (FRS). Materials and Methods For this retrospective study, electronic health records for 829 asymptomatic patients (mean age, 57.9 years; 451 women, 378 men) who underwent nonenhanced CT colonography screening between April 2004 and March 2005 were reviewed for subsequent cardiovascular events; mean follow-up interval was 11.2 years +/- 2.8 (standard deviation). Institutional review board approval was obtained. CT-based AAC was retrospectively quantified as a modified Agatston score by using a semiautomated tool. Kaplan-Meier curves and Cox proportional hazards models were used for time-to-event analysis; receiver operating characteristic curves and net reclassification improvement compared predictive abilities of AAC and FRS. Results An index cardiovascular event occurred after CT in 156 (19%) of 829 patients (6.7 years +/- 3.5, including heart attack in 39 [5%] and death in 79 [10%]). AAC was higher in the cardiovascular event cohort (mean AAC, 3478 vs 664; P < .001). AAC was a strong predictor of cardiovascular events at both univariable and multivariable Cox modeling, independent of FRS (P < .001). Kaplan-Meier plots showed better separation with AAC over FRS. The area under the receiver operating characteristic curve (AUC) was higher for AAC than FRS at all evaluated time points (eg, AUC of 0.82 vs 0.64 at 2 years; P = .014). By using a cutoff point of 200, AAC improved FRS risk categorization with net reclassification improvement of 35.4%. Conclusion CT-based abdominal aortic calcification was a strong predictor of future cardiovascular events, outperforming the Framingham risk score. This finding suggests a potential opportunistic role in abdominal nonenhanced CT scans performed for other clinical indications. (c) RSNA, 2018.

PMID- 30277445 TI - Microcalcifications Detected at Screening Mammography: Synthetic Mammography and Digital Breast Tomosynthesis versus Digital Mammography. AB - Purpose To compare the performance of two-dimensional synthetic mammography (SM) plus digital breast tomosynthesis (DBT) versus conventional full-field digital mammography (FFDM) in the detection of microcalcifications on screening mammograms. Materials and Methods In this retrospective multireader observer study, 72 consecutive screening mammograms recalled for microcalcifications from June 2015 through August 2016 were evaluated with both FFDM and DBT. The data set included 54 mammograms with benign microcalcifications and 18 mammograms with malignant microcalcifications, and 20 additional screening mammograms without microcalcifications used as controls. FFDM alone was compared to synthetic mammography plus DBT. Four readers independently reviewed each data set and microcalcification recalls were tabulated. Sensitivity and specificity for microcalcification detection were calculated for SM plus DBT and for FFDM alone. Interreader agreement was calculated with Fleiss kappa values. Results Reader agreement was kappa value of 0.66 (P < .001) for FFDM and 0.63 (P < .001) for SM plus DBT. For FFDM, the combined reader sensitivity for all microcalcifications was 80% (229 of 288; 95% confidence interval [CI]: 74%, 84%) and for malignant microcalcifications was 92% (66 of 72; 95% CI: 83%, 97%). For SM plus DBT, the combined reader sensitivity for all microcalcifications was 75% (215 of 288; 95% CI: 69%, 80%) and for malignant microcalcifications was 94% (68 of 72; 95% CI: 86%, 98%). For FFDM, the combined reader specificity for all microcalcifications was 98% (78 of 80; 95% CI: 91%, 100%) and for malignant microcalcifications was 98% (78 of 80; 95% CI: 91%, 100%). For SM plus DBT, combined reader specificity for all microcalcifications was 95% (76 of 80; 95% CI: 88%, 99%) and for malignant microcalcifications was 95% (76 of 80; 95% CI: 88%, 99%). Mixed-effects model concluded no differences between modalities (-0.03; 95% CI: -0.08, 0.01; P = .13). Conclusion Relative to full-field digital mammography, synthetic mammography plus digital breast tomosynthesis had similar sensitivity and specificity for the detection of microcalcifications previously identified for recall at screening mammography.

Pupillometric Studies of Motor Imagery in Expert Piano Playing. AB - Motor imagery (MI; mental simulation of actions) shares certain mental representations and processes with executed movement (ME). This neurocognitive overlap between MI and ME may explain why the systematic use of MI improves skilled performance in numerous domains. Unfortunately, the attentional mechanisms underlying MI remain unresolved. Therefore, the present studies investigated the role of attentional effort (as measured by pupil dilation) in MI. We evaluated the effects of movement complexity and speed on expert pianists' pupil dilation as they physically executed and used MI to perform easy/complex and slow/fast music phrases. Results revealed that easy movements required similar levels of attentional effort during MI and ME. However, during complex movements performed at a fast speed, the correspondence between execution and imagery of movement was disrupted. PMID- 30277449 TI - Feasibility of an Internet-based positive psychological intervention for hemodialysis patients with symptoms of depression. AB - BACKGROUND: Depression is a pervasive psychological issue facing hemodialysis (HD) patients. Novel technology-based treatment strategies that deploy psychology based interventions have not been the focus for therapy and few published studies exist. The aim of the current trial is to determine the feasibility and acceptability of an Internet-based positive psychological intervention in HD patients with comorbid depressive symptoms. METHODS: HD patients (n = 14) with elevated symptoms of depression were enrolled in a single-arm pre-post trial with clinical assessments at baseline and immediately post intervention. Chairside during regularly scheduled HD treatment, patients utilized a web browser to complete online modules promoting skills for increasing positive emotion over a 5 week period using Apple IPads. Targeted skills included noting of daily positive events, gratitude, positive reappraisal, acts of kindness, and mindfulness/meditation. RESULTS: Twelve of 14 patients completed the program for an 85.7% retention rate. Participants felt satisfied with each session and offered consistently positive feedback. On average, participants visited the website 3.5 times per week. Significant improvements were evident for depressive symptoms (15.3 vs. 10.9; p = 0.04), as per the Center for Epidemiological Studies Depression Scale. CONCLUSIONS: An innovative Internet-based positive psychological intervention represents a feasible and useful therapeutic option for HD patients with depressive symptoms.

PMID- 30277451 TI - Examining the Return on Investment of the Breath of Life Mobile Pediatric Asthma Clinic in a Rural Region with Small Metropolitan Statistical Areas. AB - The current study sought to examine the return on investment (ROI) of a mobile pediatric asthma clinic in a rural region with small metropolitan statistical areas, in terms of reduced costs attributed to preventable emergency department visits, inpatient admission, school absenteeism, cost of education, and parent work absenteeism. For fiscal years 2015 and 2016, an average return of $1.32 and a community ROI of $1.45 was estimated. Estimated benefits were $445,125.00 and cost avoidance was $263,853.01. A mobile pediatric asthma clinics operating in less densely populated regions is able to yield a positive ROI. PMID- 30277452 TI - Hospitals' Preparedness to Treat Pediatric Patients During Mass Casualty Incidents. AB - OBJECTIVES: Little is known about the preparedness of hospitals to care for pediatric patients during a major incident in Japan. This study assessed the disaster preparedness of a children's hospital in Japan by using a disaster drill.Materials and MethodsWe performed a triage drill with all hospitalized patients. The triage tags and medical records were reviewed retrospectively. We determined the efficacy of triage education, the validity of the Simple Triage and Rapid Treatment (START) method for children, and the potential need for evacuation through the disaster drill. RESULTS: This study highlights 3 important issues about the hospital's preparedness. First, it is difficult to promote disaster education for staff who are not well trained on handling disasters. Second, the START method is suitable for children older than 5 years, but it has a high rate of over-triaging among younger children. Third, approximately 40% of patients who are coded as immediate may require transportation resources in a hospital evacuation. CONCLUSIONS: Our findings suggest that disaster preparedness, such as educating hospital staff regarding disasters and establishing evacuation systems for a number of pediatric patients when a disaster happens, is essential for caring for hospitalized children during a mass casualty incident.

AB - A great deal of research has focused on acculturation and enculturation, which represent the processes of adapting to a new culture. Despite this growing literature, results have produced inconsistent findings that may be attributable to differences in terms of the instruments used to assess acculturation and enculturation. Utilizing a 3-year longitudinal data set (with 1-year lags between assessments), the present study explored the psychometric properties of the Bicultural Involvement Questionnaire-Short Version (BIQ-S) and the Acculturation Rating Scale for Mexican Americans II (ARSMA-II) and examined the overlap between changes in these measures as they relate to internalizing and externalizing problem behavior. The present sample consisted of 216 immigrant Latino youth (43% boys; mean age 13.6 years at baseline; SD = 1.44 years, range 10 to 17). Exploratory structural equation modeling identified factor structures for the BIQ S and ARSMA-II that diverged from their hypothesized structure. Growth curve models also indicate divergence between the BIQ-S and ARSMA-II in terms of change in acculturation and enculturation processes. Finally, the present findings emphasized that measures of acculturation and enculturation are not equivalent in terms of their effects on internalizing and externalizing problems. PMID- 30277454 TI - The effects of Trolox on the quality of sperm from captive squirrel monkey during liquefaction in the extender ACP-118TM. AB - SummaryThe aim of this study was to evaluate the effect of incubating semen for different periods (90, 270 or 450 min) with or without Trolox(r) (100 or 150 uM) on the quality of sperm from Saimiri collinsi. Sperm motility, vigour, and plasma membrane integrity (PMI) were evaluated in both fresh semen and semen incubated for different time periods, i.e. 90, 270 or 450 min of incubation. Supplementation of semen extender with Trolox(r) 100 uM improved sperm motility, vigour and PMI for up to 270 min of incubation. PMID- 30277455 TI - Effect of chromium supplementation on growth performance, meal pattern, metabolic and antioxidant status and insulin sensitivity of summer-exposed weaned dairy calves. AB - Stressful situations may result in serum chromium (Cr) depletion with increased urinary excretion of the mineral and increased Cr requirements. The objective of this study was to investigate the effects of Cr supplementation on growth performance, feeding behavior, blood metabolites and hormones, indicators of oxidative stress and glucose-insulin kinetics of summer-exposed weaned dairy calves. In total, 48 Holstein female calves (63 days of age; 77.0+/-1.45 kg of BW) were assigned randomly to one of two treatments: (1) a control group with no supplemental Cr (Cr-), and (2) a supplemental Cr group (Cr+) to supply 0.05 mg Cr as Cr-methionine/kg of BW0.75. Chromium was provided in the starter feed and adjusted weekly based on BW over the experimental period. All calves were on experiment for 4 weeks after weaning. The average maximum temperature-humidity index was 76.1 units during the study period, indicating a mild degree of environmental heat load. Results indicated that in summer-exposed dairy calves, increased dietary Cr provision tended to decrease fecal score, tended to change rumination pattern, increased antioxidant capacity by increasing serum concentration of catalase, but had no effects on growth performance, metabolic status or peripheral glucose and insulin metabolism.

Our findings raise important questions about increased mortality rates associated with chikungunya. PMID- 30277457 TI - Apathy alters emotional arousal in chronic schizophrenia. AB - BACKGROUND: Within the heterogeneity of schizophrenia, apathy constitutes an independent cluster of negative symptoms associated with poor outcomes. Attempts to identify an emotional deficit in patients who have schizophrenia with negative symptoms have yielded mixed results, and studies that focus on the relationship between apathy and emotional disorders are lacking. METHODS: We set out to remedy this shortcoming using a validated battery of film excerpts to induce positive and negative emotions in patients with chronic schizophrenia with (n = 20) or without (n = 20) apathy, and in controls (n = 20) comparable for age, sex and socioeconomic status. We assessed emotions using an innovative but validated technique to evaluate tonic and phasic electrodermal activity and subjective feelings using a standardized visual analogue scale. RESULTS: Using a qualitative measure of apathy, we did not find a specific decrease in tonic activity during the induction of positive emotions. However, we did observe that patients with apathy showed reduced tonic activity independent of valence (i.e., for both positive and negative emotions) compared with controls and patients without apathy. Moreover, the quantitative measure of apathy (Apathy Evaluation Scale) was the only significant factor, explaining 24% of the variance in tonic activity during induction of positive emotions after controlling for confounding factors. LIMITATIONS: Electrodermal activity was the only physiologic measure we acquired. We induced several emotions sequentially that might have overlapped with each other, but we added an emotional "washout" period and randomized the order of each film excerpt to limit this possibility. CONCLUSION: Taken together, these results suggest that apathy in schizophrenia could impair tonic activity during positive emotions. Treatments aimed at enhancing positive emotions may help alleviate apathy in schizophrenia. PMID- 30277460 TI - Bioresorbable Vascular Scaffolds in coronary chronic total occlusions. Clinical, vasomotor and optical coherence tomography findings at 3-year follow-up (ABSORB CTO study). AB - AIMS: Percutaneous treatment of coronary chronic total occlusion (CTO) is associated with important arterial remodelling after successful recanalization. Bioresorbable vascular scaffold (BVS) implantation in CTO has been shown feasible and can be of interest when the scaffold achieves complete bioresorption. We sought to evaluate the 3-year results in terms of clinical events, serial imaging outcomes and the vasomotion response in CTO lesions successfully treated with BVS. METHODS AND RESULTS: A total of 33 patients (35 CTO lesions) successfully treated with BVS were included in ABSORB-CTO study. Clinical outcomes, quantitative coronary angiography (QCA) and optical coherence tomography (OCT) assessment were analysed at 1-and 3-year follow-up. Vasomotion examination was also performed at 3 years. At 3-year, cumulative target vessel re-occlusion was observed in 4 lesions(11.4%). By QCA, in-scaffold segment presented a lumen loss of 0.23+/-0.46 mm compared with baseline procedure (p=0.001) and a lumen gain of 0.05+/-0.29 mm between 1 and 3 years (p=0.220). By OCT the mean neointimal area stenosis progressed from 11.45% at 12 months to 17.10% at 36 months (p<0.001) and mean scaffold area increased continuously at 12 (+12%;p<0.001) and at 36 months (+14.85%;p=0.001). Late acquired incomplete scaffold apposition (LAISA) observed at 12 months in 3 patients was completely undetectable at 3 years. Most of cases responded to endothelial-dependent vasomotor stimuli (69%). Vasoconstriction to acetylcholine was the predominant response (45%). CONCLUSIONS: Successful recanalization of coronary-CTO with BVS implantation is associated with favourable clinical and imaging outcomes. Despite vessel motility restoration, successfully treated CTO remain with signs of endothelial dysfunction.

PMID- 30277458 TI - Rif1 inhibits replication fork progression and controls DNA copy number in Drosophila. AB - Control of DNA copy number is essential to maintain genome stability and ensure proper cell and tissue function. In Drosophila polyploid cells, the SNF2-domain containing SUUR protein inhibits replication fork progression within specific regions of the genome to promote DNA underreplication. While dissecting the function of SUUR's SNF2 domain, we identified an interaction between SUUR and Rif1. Rif1 has many roles in DNA metabolism and regulates the replication timing program. We demonstrate that repression of DNA replication is dependent on Rif1. Rif1 localizes to active replication forks in a partially SUUR-dependent manner and directly regulates replication fork progression. Importantly, SUUR associates with replication forks in the absence of Rif1, indicating that Rif1 acts downstream of SUUR to inhibit fork progression. Our findings uncover an unrecognized function of the Rif1 protein as a regulator of replication fork progression. PMID- 30277462 TI - Pre-infarction Angina and Culprit Lesion Morphologies in Patients with a First ST segment Elevation Acute Myocardial Infarction: Insights from In Vivo Optical Coherence Tomography. AB - AIMS: This study aimed to evaluate the relationship between pre-infarction angina (PIA) and in vivo culprit lesion characteristics as assessed by intravascular optical coherence tomography (OCT) in patients with a first ST-segment elevation myocardial infarction (STEMI). METHODS AND RESULTS: A total of 305 consecutive patients with a first STEMI who underwent OCT imaging of culprit lesions during primary percutaneous coronary intervention (PCI) were prospectively enrolled. OCT findings of the culprit plaque were compared between patients with (n=206) and without PIA (n=99). Patients with PIA showed lower rates of thin-cap fibroatheroma (TCFA) (62.6% vs. 80.8%, P=0.001) and plaque rupture (56.8% vs. 72.7%, P=0.007), smaller maximum ruptured cavity areas (1.10+/-1.04 mm2 vs. 1.53+/-1.20 mm2, P=0.002), and more severe residual luminal narrowing (P=0.015) with a higher incidence of white residual thrombus (68.4% vs. 50.0%, P=0.003) at the culprit lesions than patients without PIA. No significant differences in clinical outcomes were observed at the 1-year follow-up. CONCLUSIONS: In patients with a first STEMI, PIA was significantly associated with a lower incidence of TCFA and plaque rupture, a smaller ruptured cavity area, more white residual thrombi, and more severe lumen stenosis at the culprit lesions.

AB - Spinal cord injury (SCI) is a devastating neurological condition for which there are currently no effective treatment options to restore function. A major obstacle to the development of new therapies is our fragmentary understanding of the coordinated pathophysiological processes triggered by damage to the human spinal cord. Here, we describe a systems biology approach to integrate decades of small-scale experiments with unbiased, genome-wide gene expression from the human spinal cord, revealing a gene regulatory network signature of the pathophysiological response to SCI. Our integrative analyses converge on an evolutionarily conserved gene subnetwork enriched for genes associated with the response to SCI by small-scale experiments, and whose expression is upregulated in a severity-dependent manner following injury and downregulated in functional recovery. We validate the severity-dependent upregulation of this subnetwork in rodents in primary transcriptomic and proteomic studies. Our analysis provides systems-level view of the coordinated molecular processes activated in response to SCI. PMID- 30277464 TI - First prospective multicenter experience with left distal transradial approach for coronary chronic total occlusion interventions using a 7-french glidesheath slender. AB - AIMS: to assess the feasibility and safety of the left distal transradial artery (LDTRA) approach using a 7 Fr Glidesheath Slender for chronic total occlusion (CTO) percutaneous coronary interventions (PCIs). METHODS AND RESULTS: From March to May 2018 a total of 41 consecutive CTO PCIs were performed through LDTRA access using a 7 Fr Glidesheath Slender. Technical and procedural success, defined as achievement of technical success using the initially selected LDTRA access with no in-hospital mayor adverse cardiovascular events (MACE), were respectively 90,3% and 78%. Failure in achieving LDTRA access was 17,1%. There were no vascular access-site complications such as no post-procedural LDRAOs. Doppler ultrasound imaging of the left distal radial artery at 1 month was available in 67,6% of patients with only one case (4.3%) of LDRAO in a female patient. CONCLUSIONS: LDTRA approach using a 7 Fr Glidesheath Slender for CTO PCIs is feasible and associated with high rate of procedural success and low rate of vascular access-site complications.

AB - A large amount of parallel silicon nanowires, placed perpendicularly to a silicon substrate (silicon nanowire forests), have been contacted and assembled in order to fabricate legs of a thermoelectric generator. This paper reports the measurement of the main parameter for thermoelectric applications, which is the thermal conductivity. The reported value, which confirms the strong reduction of the thermal conductivity in nanostructures, is measured on a large amount (>107) of parallel nanowires with a diameter variable in the range 60-120 nm, and takes into account eventual non-uniformities which are unavoidable on surfaces of several mm2. As silicon nanowire forests are very thin, it has been necessary to develop a suitable measurement apparatus. The fabrication of devices based on silicon nanowire forests, the apparatus and the measurement procedure, as well as the the results, are illustrated and discussed. PMID- 30277466 TI - A comparison between two dolutegravir-based two-drug regimens as switch strategies in a multicentre cohort of HIV-1-infected patients. AB - BACKGROUND: Two-drug regimens are increasingly used in clinical practice as switch strategies. We compared the efficacy and safety of two dolutegravir (DTG) based dual therapies: DTG plus lamivudine (3TC group) versus DTG plus rilpivirine (RPV group). METHODS: In a multicentre cohort of virologically suppressed (HIV RNA <50 copies/ml) HIV+ patients switching to DTG+3TC or DTG+RPV we analysed the incidence of virological failures (VF) and treatment discontinuations (TD), as well as their predictors. RESULTS: We analysed 416 patients, 229 in the 3TC group and 187 in the RPV group. The 3TC group, during 344.4 person-years of follow-up (PYFU), had 10 VF without the emergence of resistance mutations, while 30 patients discontinued the regimen. In the RPV group, during 371.0 PYFU, there were 5 VF (1 developed non-nucleoside reverse transcriptase inhibitor mutations Y181C and E138Q) and 13 TD. The estimated probability of remaining free from VF at 48 weeks showed no significant difference between groups (log-rank 0.172). We found a higher risk of VF in patients with peak viral load >500,000 copies/ml in both treatment groups (log-rank P=0.004 in each group). The estimated probability of remaining in the study regimen at week 48 was 89.0% with DTG+3TC and 96.1% with DTG+RPV (log-rank 0.015). After adjusting for potential confounders, treatment group was not associated with TD. A significant decrease in total cholesterol was observed at week 48 in both groups while renal function remained unchanged. CONCLUSIONS: DTG+RPV and DTG+3TC were compared in populations with different characteristics in clinical practice: both regimens showed good effectiveness and improved lipid profile. PMID- 30277468 TI - In situ and ex situ NMR for battery research. AB - A rechargeable battery stores readily convertible chemical energy to operate a variety of devices such as mobile phones, laptop computers, electric automobiles, etc. A battery generally consists of four components: a cathode, an anode, a separator and electrolytes. The properties of these components jointly determine the safety, the lifetime, and the electrochemical performance. They also include, but are not limited to, the power density and the charge as well as the recharge time/rate associated with a battery system. An extensive amount of research is dedicated to understanding the physical and chemical properties associated with each of the four components aimed at developing new generations of battery systems with greatly enhanced safety and electrochemical performance at a significantly reduced cost for large scale applications. Advanced characterization tools are a prerequisite to fundamentally understanding battery materials. Considering that some of the key electrochemical processes can only exist under in situ conditions, which can only be captured under working battery conditions when electric wires are attached and current and voltage are applied, make in situ detection critical. Nuclear magnetic resonance (NMR), a non-invasive and atomic specific tool, is capable of detecting all phases, including crystalline, amorphous, liquid and gaseous phases simultaneously and is ideal for in situ detection on a working battery system. Ex situ NMR on the other hand can provide more detailed molecular or structural information on stable species with better spectral resolution and sensitivity. The combination of in situ and ex situ NMR, thus, offers a powerful tool for investigating the detailed electrochemistry in batteries. PMID- 30277469 TI - Two-dimensional noise reconstruction in proton computed tomography using distance driven filtered back-projection of simulated projections. AB - We present a formalism for two-dimensional (2D) noise reconstruction in proton computed tomography (pCT). This is necessary for the application of fluence modulated pCT (FMpCT) since it permits image noise prescription and the corresponding proton fuence optimization. We aimed at extending previously published formalisms to account for the impact of multiple Coulomb scattering (MCS) on projection noise, and the use of filtered back projection (FBP) reconstruction along curved paths with distance driven binning (DDB). 2D noise reconstruction for a beam of protons with parallel initial momentum vectors, and for projections binned both at the rear tracker and with DDB, was established. Monte Carlo (MC) simulations of pCT scans of a water cylinder were employed to generate pCT projections and to calculate their noise for use in 2D noise reconstruction. These were compared to results from an analytical model accounting for MCS for rear tracker binning as well as against the previously published central pixel model which ignores MCS. Image noise reconstructed with the formalism for rear tracker binning and DDB were compared to MC results using annular regions of interest (ROIs). Agreement better than 8% was obtained between the noise of projections calculated with MC simulation and our model. Noise from annular ROIs agreed with our noise reconstructions for rear tracker binning and DDB. The central pixel model ignoring MCS underestimated projection and thus image noise by up to 40% towards the object's edge. The use of DDB decreased the image noise towards the object's edge when compared to rear tracker binning and yielded more uniform noise throughout the image. MCS should not be neglected when predicting image noise for pixels away from the center of an object in a pCT scan due to the increasing influence of the gradient of the object's hull closer to the edges. PMID- 30277470 TI - Porous SnO2-Cu x O nanocomposite thin film on carbon nanotubes as electrodes for high performance supercapacitors. AB - Metal oxides are promising materials for supercapacitors due to their high theoretical capacitance. However, their poor electrical conductivity is a major challenge. Hybridization with conductive nanostructured carbon-based materials such as carbon nanotubes (CNTs) has been proposed to improve the conductivity and increase the surface area. In this work, CNTs are used as a template for synthesizing porous thin films of SnO2-CuO-Cu2O (SnO2-Cu x O) via an electroless deposition technique. Tin, with its high wettability and electrical conductivity, acts as an intermediate layer between copper and the CNTs and provides a strong interaction between them. We also observed that by controlling the interfacial characteristics of CNTs and varying the composition of the electroless bath, the SnO2-Cu x O thin film morphology can be easily manipulated. Electrochemical characterizations show that CNT/SnO2-Cu x O nanocomposite possesses pseudocapacitive behavior that reaches a specific capacitance of 662 F g-1 and the retention is 94% after 5000 cycles, which outperforms any known copper and tin-based supercapacitors in the literature. This excellent performance is mainly attributed to high specific surface area, small particle size, the synergistic effect of Sn, and conductivity improvement by using CNTs. The combination of CNTs and metal oxides holds promise for supercapacitors with improved performance. PMID- 30277472 TI - Cigarette smoke and HIV synergistically affect lung pathology in cynomolgus macaques. AB - In the era of combined antiretroviral therapy (cART), lung diseases such as chronic bronchitis (CB) and chronic obstructive pulmonary disease (COPD) are common among persons living with HIV (PLWH), particularly smokers. Although smoking is highly prevalent among PLWH, HIV may be an independent risk factor for lung diseases; however, the role of HIV and cigarette smoke (CS) and their potential interaction in the development of chronic lung diseases among PLWH has not been delineated. To investigate this interaction, cynomolgus macaques were exposed to CS and/or simian-adapted human immunodeficiency virus (SHIV) and treated with cART. The development of CB and the lung functions were evaluated following CS+/-SHIV treatment. The results showed that in the lung, SHIV was a strong independent risk factor for goblet cell metaplasia/hyperplasia and mucus formation, MUC5AC synthesis, loss of tight junction proteins, and increased expression of Th2 cytokines/transcription factors. In addition, SHIV and CS synergistically reduced lung function and increased extrathoracic tracheal ring thickness. Interestingly, SHIV infection generated significant numbers of HIV gp120+ epithelial cells (HGECs) in small airways and alveoli, and their numbers doubled in CS+SHIV-infected lungs. We conclude that even with cART, SHIV independently induces CB and pro-COPD changes in the lung, and the effects are exacerbated by CS. PMID- 30277471 TI - CD84 regulates PD-1/PD-L1 expression and function in chronic lymphocytic leukemia. AB - Chronic lymphocytic leukemia (CLL) is characterized by clonal proliferation and progressive accumulation of mature B lymphocytes in the peripheral blood, lymphoid tissues, and bone marrow. CLL is characterized by profound immune defects leading to severe infectious complications. T cells are numerically, phenotypically, and functionally highly abnormal in CLL, with only limited ability to exert antitumor immune responses. Exhaustion of T cells has also been suggested to play an important role in antitumor responses. CLL-mediated T cell exhaustion is achieved by the aberrant expression of several inhibitory molecules on CLL cells and their microenvironment, prominently the programmed cell death ligand 1/programmed cell death 1 (PD-L1/PD-1) receptors. Previously, we showed that CD84, a member of the SLAM family of receptors, bridges between CLL cells and their microenvironment. In the current study, we followed CD84 regulation of T cell function. We showed that cell-cell interaction mediated through human and mouse CD84 upregulates PD-L1 expression on CLL cells and in their microenvironment and PD-1 expression on T cells. This resulted in suppression of T cell responses and activity in vitro and in vivo. Thus, our results demonstrate a role for CD84 in the regulation of immune checkpoints by leukemia cells and identify CD84 blockade as a therapeutic strategy to reverse tumor-induced immune suppression. PMID- 30277473 TI - beta-Blockers and bone health. AB - Bone metabolism is controlled by endocrine, paracrine, and inflammatory signals that continuously operate in health and disease. While these signals are critical for skeletal adaptation during development, longitudinal growth, and repair, disturbances such as sex hormone deficiency or chronic inflammation have unambiguously been linked to bone loss and skeletal fragility across species. In the current issue of the JCI, Khosla et al. evaluated the role of sympathetic outflow and present evidence to support the idea that the sympathetic nervous system regulates bone metabolism in humans, primarily via the beta1-adrenergic receptor. PMID- 30277474 TI - E-cadherin expression on multiple myeloma cells activates tumor-promoting properties in plasmacytoid DCs. AB - Plasmacytoid dendritic cells (pDCs) play a key role in antiviral responses by producing type-1 IFNs. However, recent studies showed that pDCs induce immune suppression and promote tumor growth in human ovarian cancer and myeloma. The molecular mechanisms underlying pDC acquisition of these properties are unknown. Here we show that human pDCs activated by CpG inhibited growth and induced apoptosis in myeloma cells via secreted IFN-alpha, but direct contact with myeloma cells converted pDCs into tumor-promoting cells by suppressing pDC IFN alpha production. E-cadherin, expressed on both myeloma cells and pDCs, mediated these effects via a homophilic interaction - activation of E-cadherin signaling upregulated and activated TNFAIP3 to interact with TLR9, resulting in TLR9 ubiquitination and degradation, and inhibition of IFN-alpha production in pDCs. These findings were supported by an in vivo study in which pDC depletion induced tumor regression and better survival in the Vk*MYC myeloma mouse model. Furthermore, IFNAR1 expression level positively correlated to overall survival of patients with multiple myeloma (MM), and the IFN-alpha level in patient bone marrow was significantly lower than that in marrow of healthy individuals. This study reveals a novel mechanism underlying how MM tumors educate pDCs in their microenvironment and provides new targets for improving the treatment of MM.

Lack of availability of tools to study the specifics of renin regulation has limited advances in this field. In the current issue of the Journal of Clinical Investigation, Martinez and colleagues used the genome-wide assessment of the chromatin status of cells and uncovered a unique set of super-enhancers that determine the identity of renin cells. The renin super-enhancers play a key role in the molecular memory of renin cell function, a mechanism at the core of preserving homeostasis.

PMID- 30277479 TI - Billing and Volunteers Substantially Reduced School-Located Influenza Vaccination Costs, 2 Oregon Counties, 2010-2011. AB - BACKGROUND AND OBJECTIVES: After the 2009 pandemic influenza seasons, the financial sustainability of school-located vaccination (SLV) clinics drew much attention. This study estimated and compared the labor costs of SLV clinics and reimbursements for influenza vaccinations for students attending 5 schools in 2 Oregon counties during 2010-2011. DESIGN/SETTING: Using a biweekly, Web-based survey, staff and volunteers prospectively tracked the time they spent on SLV clinic planning, implementation, and billing. They also tracked claims submitted and reimbursements by payment source. MAIN OUTCOME MEASURE: We report labor hours and associated costs for implementing school-based vaccination clinics; number of claims submitted and the reimbursement rate; and total and net costs. RESULTS: In county A, 260 doses were administered at a total cost of $5009 and received $3620 in payment. For county B, 165 doses were administered at a cost of $5598 and received $3807 in payments. With billing, the net cost per dose decreased from $19.74 to $8.57 and $38.08 to $16.17, for county A and county B, respectively. CONCLUSIONS: Reimbursements reduced cost per dose by 48% across SLV clinics across both Oregon counties. Local health departments can bill local health insurers to offset costs for implementing school-based vaccination clinics. Efforts to set up billing processes require dedicated billing staff who can effectively manage claims submission processes with multiple health insurers. PMID- 30277476 TI - Targeted delivery of immune therapeutics to lymph nodes prolongs cardiac allograft survival. AB - The targeted delivery of therapeutic drugs to lymph nodes (LNs) provides an unprecedented opportunity to improve the outcomes of transplantation and immune mediated diseases. The high endothelial venule is a specialized segment of LN vasculature that uniquely expresses peripheral node addressin (PNAd) molecules. PNAd is recognized by MECA79 mAb. We previously generated a MECA79 mAb-coated microparticle (MP) that carries tacrolimus. Although this MP trafficked to LNs, it demonstrated limited therapeutic efficacy in our transplant model. Here, we have synthesized a nanoparticle (NP) as a carrier of anti-CD3, and optimized the conjugation strategy to coat the NP surface with MECA79 mAb (MECA79-anti-CD3-NP) to enhance LN accumulation. As compared with nonconjugated NPs, a significantly higher quantity of MECA79-NPs accumulated in the draining lymph node (DLN). Many MECA79-NPs underwent internalization by T cells and dendritic cells within the LNs. Short-term treatment of murine cardiac allograft recipients with MECA79-anti CD3-NP resulted in significantly prolonged allograft survival in comparison with the control groups. Prolonged graft survival following treatment with MECA79-anti CD3-NP was characterized by a significant increase in intragraft and DLN Treg populations. Treg depletion abrogated the prolongation of heart allograft survival. We believe this targeted approach of drug delivery could redefine the methods of administering immune therapeutics in transplantation. PMID- 30277475 TI - Targeting nuclear receptor NR4A1-dependent adipocyte progenitor quiescence promotes metabolic adaptation to obesity. AB - Adipocyte turnover in adulthood is low, suggesting that the cellular source of new adipocytes, the adipocyte progenitor (AP), resides in a state of relative quiescence. Yet the core transcriptional regulatory circuitry (CRC) responsible for establishing a quiescent state and the physiological significance of AP quiescence are incompletely understood. Here, we integrate transcriptomic data with maps of accessible chromatin in primary APs, implicating the orphan nuclear receptor NR4A1 in AP cell-state regulation. NR4A1 gain and loss of function in APs ex vivo decreased and enhanced adipogenesis, respectively. Adipose tissue of Nr4a1-/- mice demonstrated higher proliferative and adipogenic capacity compared with that of WT mice. Transplantation of Nr4a1-/- APs into the subcutaneous adipose tissue of WT obese recipients improved metrics of glucose homeostasis relative to administration of WT APs. Collectively, these data identify NR4A1 as a previously unrecognized constitutive regulator of AP quiescence and suggest that augmentation of adipose tissue plasticity may attenuate negative metabolic sequelae of obesity. PMID- 30277480 TI - Flow cytometry analysis of adrenoceptors expression in human adipose-derived mesenchymal stem/stromal cells. AB - Mesenchymal stem/stromal cells (MSCs) were identified in most tissues of an adult organism. MSCs mediate physiological renewal, as well as regulation of tissue homeostasis, reparation and regeneration. Functions of MSCs are regulated by endocrine and neuronal signals, and noradrenaline is one of the most important MSC regulators. We provided flow cytometry analysis of expression of adrenergic receptors on the surface of human MSCs isolated from ten different donors. We have found that the expression profile of adrenergic receptors in MSCs vary significantly between donors. We also showed that alpha1A-adrenoceptor expression is upregulated under the action of noradrenaline. We share our flow cytometry raw data, as well as processing of these data on a flow cytometry repository for freely downloading. PMID- 30277481 TI - Free-electron laser data for multiple-particle fluctuation scattering analysis. AB - Fluctuation X-ray scattering (FXS) is an emerging experimental technique in which solution scattering data are collected using X-ray exposures below rotational diffusion times, resulting in angularly anisotropic X-ray snapshots that provide several orders of magnitude more information than traditional solution scattering data. Such experiments can be performed using the ultrashort X-ray pulses provided by a free-electron laser source, allowing one to collect a large number of diffraction patterns in a relatively short time. Here, we describe a test data set for FXS, obtained at the Linac Coherent Light Source, consisting of close to 100 000 multi-particle diffraction patterns originating from approximately 50 to 200 Paramecium Bursaria Chlorella virus particles per snapshot. In addition to the raw data, a selection of high-quality pre-processed diffraction patterns and a reference SAXS profile are provided. PMID- 30277482 TI - RNA-seq of macrophages of amoeboid or mesenchymal migratory phenotype due to specific structure of environment. AB - M2-polarized macrophages have been shown to adapt their 3D migration mode to physical properties of surrounding extracellular matrix. They migrate in the integrin-mediated adhesion and proteolytic activity-dependent "mesenchymal" mode in stiff matrices and in the integrin and protease-independent "amoeboid" mode in low density, porous environments. To find out what impact the switching between the migration modes has on expression of both protein-coding and non-coding genes we employed RNA sequencing of total RNA depleted of ribosomal RNA isolated from macrophages migrating in either mode in 3D collagens. Differentially expressed genes from both categories have been detected and the changes in expression of selected genes were further validated with RT-qPCR. The acquired data will facilitate better understanding of how mechanical properties of tissue microenvironment reflect in macrophage immune function and how the transitions between mesenchymal and amoeboid migratory modes are regulated at the gene expression level. PMID- 30277484 TI - Sensing caspase-1 activity using activatable 19F MRI nanoprobes with improved turn-on kinetics. AB - Activatable 19F MRI nanoprobes for sensing caspase-1 activity were developed. Tandem repetition of substrate peptide sequences improved the turn-on response of nanoprobes, allowing detection of caspase-1 activity by 19F MRI. In vivo immune response was successfully imaged using the new nanoprobe. PMID- 30277485 TI - UV/visible light active CuCrO2 nanoparticle-SnO2 nanofiber p-n heterostructured photocatalysts for photocatalytic applications. AB - CuCrO2 nanoparticle decorated SnO2 nanofiber composites have been prepared as novel p-n heterostructured semiconductor photocatalysts for the degradation of organic pollutants in wastewater. The composite structure was achieved via drop casting of various amounts of hydrothermally derived CuCrO2 nanoparticles on electrospun SnO2 nanofibers. The microstructural and morphological features of each semiconductor and the formation of p-n heterojunctions between them were characterized. In addition, the photo-response and electrochemical properties of the samples were determined. The photocatalytic activity of the heterostructured photocatalysts was investigated systematically as a function of the amount of CuCrO2 nanoparticles in the samples. Experimental results showed that the optimal decoration amount was 0.6 wt% CuCrO2 on SnO2. This composite photocatalyst displayed a 41% higher rate constant value compared to pure SnO2 nanofibers in the degradation of methylene blue dye molecules and reached 83% degradation under UV/visible light irradiation after 1 h. The increase in the photocatalytic activity was ascribed to the incorporation of Cr3+ and Cu+ cations into the SnO2 host lattice and the more effective electron-hole pair separation in the heterostructured sample. The presented data here are highly convincing in comparison to those of UV active p-n heterostructured photocatalysts reported previously in the literature. Therefore, this work opens the way to develop visible light active p-n heterostructured semiconductor photocatalysts using p type delafossites with n-type oxides. PMID- 30277486 TI - Lifetime and nonlinearity of modulated surface plasmon for black phosphorus sensing application. AB - Black phosphorus surface plasmon (BPSP) is a new promising candidate material for electromagnetic field confinement at the subwavelength scale. Here, we theoretically investigated the light confinement, second-order nonlinearity and lifetimes of tunable surface plasmons in nanostructured black phosphorus nanoflakes with superstrates. The grating structure can enhance the local optical field of the fundamental wave (FW) and second harmonic wave (SHW) due to the surface plasmon resonance. Based on the coupled mode theory (CMT), a theoretical model for the nanostructured black phosphorus was established to study the spectrum features of FW. The lifetimes of the plasmonic resonant modes were investigated with the finite difference time domain (FDTD) simulations and CMT. Since the permittivity of black phosphorus depends on its Fermi energy and electron scattering rate, the lifetimes of plasmonic absorption modes are tunable with both the Fermi energy and scattering rate. The intensity, wavelengths and spectral width of BPSP resonance modes and their lifetimes can be precisely controlled with the Fermi energy, scattering rate, side length and refractive index of the superstrate. The sensitivity is described by varying the refractive index of the superstrate such as an aqueous solution. We have introduced a second order nonlinear source to investigate the SHW of nanostructured black phosphorus. This paper presents the corner/edge energy distribution and the tunable lifetime of BPSP as well as their unprecedented capability of photon manipulation for second-order nonlinearity within the deep subwavelength scale. The configuration and method are useful for research of the absorption, lifetime of light and nonlinear optical processes in black phosphorus-based optoelectronic devices, especially the modulation and sensing applications. PMID- 30277483 TI - Transcriptomes of cochlear inner and outer hair cells from adult mice. AB - Inner hair cells (IHCs) and outer hair cells (OHCs) are the two anatomically and functionally distinct types of mechanosensitive receptor cells in the mammalian cochlea. The molecular mechanisms defining their morphological and functional specializations are largely unclear. As a first step to uncover the underlying mechanisms, we examined the transcriptomes of IHCs and OHCs isolated from adult CBA/J mouse cochleae. One thousand IHCs and OHCs were separately collected using the suction pipette technique. RNA sequencing of IHCs and OHCs was performed and their transcriptomes were analyzed. The results were validated by comparing some IHC and OHC preferentially expressed genes between present study and published microarray-based data as well as by real-time qPCR. Antibody-based immunocytochemistry was used to validate preferential expression of SLC7A14 and DNM3 in IHCs and OHCs. These data are expected to serve as a highly valuable resource for unraveling the molecular mechanisms underlying different biological properties of IHCs and OHCs as well as to provide a road map for future characterization of genes expressed in IHCs and OHCs. PMID- 30277487 TI - Identifying reactive organo-selenium precursors in the synthesis of CdSe nanoplatelets. AB - In the synthesis of CdSe nanoplatelets, the selenium-to-selenide reduction pathway is unknown. We study solvent-free growth of CdSe nanoplatelets and identify bis(acyl) selenides as key reactive intermediates. Based on our findings, we prepare a series of bis(acyl) selenides that provide useful precursors with tailored reactivity for liquid-phase syntheses of nanoplatelets. PMID- 30277488 TI - Potential models for the simulation of methane adsorption on graphene: development and CCSD(T) benchmarks. AB - Different force fields for the graphene-CH4 system are proposed including pseudo atom and full atomistic models. Furthermore, different charge schemes are tested to evaluate the electrostatic interaction for the CH4 dimer. The interaction parameters are optimized by fitting to interaction energies at the DFT level, which were themselves benchmarked against CCSD(T) calculations. The potentials obtained with both the pseudo-atom and full atomistic approaches describe accurately enough the average interaction in the methane dimer as well as in the graphene-methane system. Moreover, the atom-atom potentials also correctly provide the energies associated with different orientations of the molecules. In the atomistic models, charge schemes including small charges allow for the adequate representation of the stability sequence of significant conformations of the methane dimer. Additionally, an intermediate charge of -0.63e on the carbon atom in methane leads to bond energies with errors of ca. 0.07 kcal mol-1 with respect to the CCSD(T) values for the methane dimer. For the graphene-methane interaction, the atom-atom potential model predicts an average interaction energy of 2.89 kcal mol-1, comparable to the experimental interaction energy of 3.00 kcal mol-1. Finally, the presented force fields were used to obtain self diffusion coefficients that were checked against the experimental value found in the literature. The no-charge and Hirshfeld charge atom-atom models perform extremely well in this respect, while the cheapest potential considered, a pseudo atom model without charges, still performs reasonably well. PMID- 30277489 TI - Antimicrobial glycoconjugate vaccines: an overview of classic and modern approaches for protein modification. AB - Glycoconjugate vaccines obtained by chemical linkage of a carbohydrate antigen to a protein are part of routine vaccinations in many countries. Licensed antimicrobial glycan-protein conjugate vaccines are obtained by random conjugation of native or sized polysaccharides to lysine, aspartic or glutamic amino acid residues that are generally abundantly exposed on the protein surface. In the last few years, the structural approaches for the definition of the polysaccharide portion (epitope) responsible for the immunological activity has shown potential to aid a deeper understanding of the mode of action of glycoconjugates and to lead to the rational design of more efficacious and safer vaccines. The combination of technologies to obtain more defined carbohydrate antigens of higher purity and novel approaches for protein modification has a fundamental role. In particular, methods for site selective glycoconjugation like chemical or enzymatic modification of specific amino acid residues, incorporation of unnatural amino acids and glycoengineering, are rapidly evolving. Here we discuss the state of the art of protein engineering with carbohydrates to obtain glycococonjugates vaccines and future perspectives. PMID- 30277490 TI - MOF-derived Mn doped porous CoP nanosheets as efficient and stable bifunctional electrocatalysts for water splitting. AB - Searching for highly active and stable bifunctional electrocatalysts for overall water splitting, e.g., for both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER), is dominating in terms of bringing future renewable energy storage and conversion processes to reality. In this work, a kind of two-dimensional ultrathin manganese (Mn) doped polyhedral cobalt phosphide (Mn-CoP) has been synthesized via the etching-carbonization phosphidation of Co-centered metal-organic frameworks. The as-prepared porous Mn CoP nanosheets had a larger specific surface area and higher porosity, furnishing them with more plentiful catalytically active sites than their counterpart hollow CoP and Mn-CoP nanoparticles, and thus showed much better electrocatalytic activity for both HER and OER in acidic and alkaline media. In addition, the Mn CoP nanosheets also demonstrated excellent durability after long-term operation. These high performances are attributed to the synergistic effects of the CoP nanosheets with intrinsic activity, the graphitic carbon and the controllable electronic structure doped by Mn and N elements. This synthetic methodology of using a classical MOF as a precursor to build a new 2D sheet-like composite may create opportunities to search for highly efficient and robust non-precious metal catalysts for energy-related reactions. PMID- 30277491 TI - Understanding the role of extracts from sea buckthorn seed residues in anti melanogenesis properties on B16F10 melanoma cells. AB - The hydroalcoholic extract of sea buckthorn (Hippophae rhamnoides L.) seed residues (HYD-SBSR) is a potential skin whitening agent. To test this material as a potential skin whitening agent, we identified and quantified the main chemical constituents of HYD-SBSR by using ultra-performance liquid chromatography coupled with quadruple time-of-flight tandem mass spectrometry (UPLC-QTOF-MS/MS) and ultra-high performance liquid chromatography coupled with triple quadruple mass spectrometry (UPLC-QQQ-MS). The anti-melanogenesis properties of HYD-SBSR on B16F10 mouse melanoma cells were analysed and the mechanism was measured on both the transcriptional and translational levels. About 24 compounds were identified. Kaempferol and its derivatives were the main compounds with a concentration of about (2796.22 +/- 31.55) MUg per g DW. The following order among the detected compounds was observed: quercetin and its derivatives > isorhamnetin and its derivatives > procyanidins. HYD-SBSR has a strong antioxidant activity but with a slight cytotoxic effect on B16F10 when treated with 45.45 MUg mL-1 and 4.55 MUg mL-1 respectively, for 48 h. HYD-SBSR has been found to significantly decrease melanin content (P < 0.01) in 24 h, 48 h, and 72 h. Additionally, strong inhibitory extracellular tyrosinase activities and decreasing intracellular tyrosinase activities were also observed (P < 0.01). HYD-SBSR shows inhibitory effects on the expression of tyrosinase (TYR) and tyrosinase-related protein 1 (TRP-1), and the secretion of TYR and TRP-1 proteins in cell lines. The protein levels of tyrosinase-related protein 2 (TRP-2) and microphthalmia-associated transcription factor (MITF) showed no significant difference. HYD-SBSR may inhibit melanin synthesis by decreasing the tyrosinase activity and down regulating the expression of TYR and TRP-1 which were probably induced by other transcriptional factors rather than MITF. PMID- 30277493 TI - An interview with Dr Karen Schindler. PMID- 30277494 TI - Xanthine oxidase inhibitor, febuxostat ameliorates the high salt intake-induced cardiac hypertrophy and fibrosis in Dahl salt-sensitive rats. AB - BACKGROUND: Xanthine oxidase (XO) is a source of reactive oxygen species production in the heart. However, pathophysiological role of XO has not been clarified in hypertensive heart disease. Thus, the present study examined impacts of high salt (HS) intake and febuxostat (Fx), a XO inhibitor in Dahl salt sensitive (Dahl-S) rats. METHODS: 8-week old, male Dahl-S rats were fed a normal salt diet (0.6% NaCl) or a HS diet (8% NaCl) for 8 weeks. A part of the rats fed the HS diet were simultaneously treated with Fx (3mg/kg/day). RESULTS: HS intake increased blood pressure and heart weight with cardiomyocyte hypertrophy and interstitial fibrosis in the left ventricle (LV), and Fx diminished them. HS increased the XO activity 4.7-fold and NADPH oxidase activity 1.5-fold, and Fx not only blocked the XO activity but also inhibited the HS-increased nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity. HS increased the expression of XO, collagen, transforming growth factor-beta1 (TGF-beta1), angiotensin-converting enzyme and angiotensin II type 1 receptor and the phosphorylation of extracellular signal-regulated kinase (ERK) in the LV, and Fx reduced the expression and phosphorylation of these proteins except XO. CONCLUSIONS: Fx ameliorates the HS intake-induced hypertension, LV hypertrophy and fibrosis with decreasing the TGF-beta1 expression and ERK phosphorylation in Dahl-S rats. Fx also down-regulates cardiac NADPH oxidase and renin-angiotensin system. The XO inhibition may be an effective therapy for hypertensive heart disease. PMID- 30277492 TI - Protein mass spectrometry extends temporal blood meal detection over polymerase chain reaction in mouse-fed Chagas disease vectors. AB - BACKGROUND: Chagas disease is highly prevalent in Latin America, and vector control is the most effective control strategy to date. We have previously shown that liquid chromatography tandem mass spectrometry (LC-MS/MS) is a valuable tool for identifying triatomine vector blood meals. OBJECTIVES: The purpose of this study was to determine blood meal detection ability as a function of method [polymerase chain reaction (PCR) vs. LC-MS/MS], time since feeding, and the effect of molting in mouse-fed triatomine insect vectors targeting hemoglobin and albumin proteins with LC-MS/MS and short interspersed nuclear elements (SINE) based PCR. METHODS: We experimentally fed Triatoma protracta on mice and used LC MS/MS to detect hemoglobin and albumin peptides over time post-feeding and post molting (<= 12 weeks). We compared LC-MS/MS results with those of a standard PCR method based on SINEs. FINDINGS: Hemoglobin-based LC-MS/MS detected blood meals most robustly at all time points post-feeding. Post-molting, no blood meals were detected with PCR, whereas LC-MS/MS detected mouse hemoglobin and albumin up to 12 weeks. MAIN CONCLUSIONS : In our study, the hemoglobin signature in the insect abdomen lasted longer than that of albumin and DNA. LC-MS/MS using hemoglobin shows promise for identifying triatomine blood meals over long temporal scales and even post-molting. Clarifying the frequency of blood-feeding on different hosts can foster our understanding of vector behavior and may help devise sounder disease-control strategies, including Ecohealth (community based ecosystem management) approaches. PMID- 30277495 TI - Tenascin-x in Amniotic Fluid and Reproductive Tissues of Pregnancies Complicated by Infection and Preterm Prelabor Rupture of Membranes. AB - Preterm prelabor rupture of membranes (PPROM), which can precede or follow intra amniotic infection/inflammation (IAI) is a poorly understood pregnancy complication. Tenascin-X (TNX) is a connective tissue extracellular matrix protein that regulates fibrillogenesis of collagens I, III and V. Our goal was to investigate the presence and level of soluble TNX (sTNX) in amniotic fluid (AF) and TNX expression in reproductive tissues of pregnancies complicated by PPROM and IAI. We prospectively recruited 334 women, pregnant with singletons that had a clinically indicated amniocentesis for genetic karyotyping, lung maturity testing, and rule-out IAI in the presence or absence of PPROM. We quantified TNX expression in fetal membranes, myometrium, cervix, and placenta using immunological methods and qRT-PCR. In pregnancies with normal outcomes, AF sTNX levels were GA-regulated with lower levels toward term. IAI significantly upregulated AF sTNX levels independent of membrane status. AF sTNX levels inversely correlated with fetal membranes tenascin XB (TNXB) mRNA level, which was significantly downregulated by IAI. Western blotting identified characteristic ~75 and ~140 kDa sTNX forms in both AF and fetal membranes. Fetal membranes, placenta, and cervix constitutively express TNX with the highest abundance in the amnion. Amnion TNX richness is significantly lost in the setting of IAI. Our results suggest fetal membranes may be a source of AF sTNX whereby protein and mRNA expression seem to be significantly impacted by inflammation independent of fetal membrane status. A more thorough understanding of TNX changes may be valuable for understanding spontaneous PPROM and to potentially develop therapeutic targets. PMID- 30277496 TI - Telomere length: lights and shadows on their role in human reproduction. AB - Telomeres are repeated DNA sequences whose main function is to preserve genome stability, protecting chromosomes ends from shortening caused by progressive loss during each cell replication or DNA damage. Telomere length regulation is normally achieved by telomerase enzyme, whose activity is progressively shut off during embryonic differentiation in somatic tissues, whereas it is maintained in germ cells, activated lymphocytes, and certain types of stem cell populations. The maintenance of telomerase activity for a longer time is necessary for germ cells to delay telomere erosion, avoiding thus chromosome segregation defects that could contribute to aneuploid or unbalanced gametes. Over the last few years, telomere biology has become an important topic in the field of human reproduction, encouraging several studies to focus on the relation between telomere length and spermatogenesis and male fertility, embryo development and quality during assisted reproductive treatment, and female pathologies as polycystic ovary, premature ovarian insufficiency and endometriosis. This review analyses whether telomere length in germ cells is related to reproduction fitness, whether telomere length is related to pathologies associated with male and female fertility and whether measurement of telomere length could represent a biomarker of germ cell and embryo quality. Telomere length could be considered a molecular marker of spermatogenesis and sperm quality and is somewhat related to male fertility potential. Fewer evidence, although promising, is available for oocytes, female (in)fertility and embryo quality. The increasing evidence for a role of telomeres and telomere length in human reproduction, indeed, has expanded the historical view of considering them just a marker of aging. Telomere length might have in the future a prognostic potential in couple infertility, especially useful to select best germ cells with the greatest potential of fertilization. PMID- 30277497 TI - E2beta Stimulates Ovine Uterine Artery Endothelial Cell H2S Production in vitro by ER-dependent Upregulation of CBS and CTH Expression. AB - Endogenous hydrogen sulfide (H2S) is a potent vasodilator and proangiogenic second messenger synthesized from L-cysteine by cystathionine beta-synthase (CBS) and cystathionine gamma-lyase (CTH). Estrogens are potent vasodilators that stimulate H2S biosynthesis in uterine arteries (UA) in vivo; however, the underlying mechanisms are unknown. We hypothesized that estrogens stimulate H2S biosynthesis in UA endothelial cells (UAEC) via specific estrogen receptor (ER) dependent mechanisms. In cultured primary UAEC, treatment with estradiol-17beta (E2beta) stimulated CBS and CTH mRNAs and proteins in a time- and concentration- dependent fashion. As little as 0.1 nM E2beta was effective in increasing CBS and CTH expressions and these stimulatory effects maximized with 10-100 nM E2beta at 48-72 h. E2beta also activated CBS and CTH promoters in UAEC, leading to CBS and CTH expression. Treatment with E2beta stimulated H2S production, which was blocked by specific inhibitors of either CBS or CTH and their combination and the ER antagonist ICI 182, 780. Treatment with either specific agonist of ERalpha or ERbeta stimulated both CBS and CTH mRNA and protein expressions and H2S production to levels similar to that of E2beta. Specific antagonist of either ERalpha or ERbeta blocked E2beta-stimulated CBS and CTH mRNA and protein expressions and H2S production. Combinations of either ERalpha or ERbeta agonists or their antagonists had no additive effects. Thus, E2beta stimulates H2S production by upregulating CBS and CTH mRNA and protein expressions through specific ERalpha or ERbeta dependent CBS and CTH transcription in UAEC in vitro. PMID- 30277498 TI - PiGx: reproducible genomics analysis pipelines with GNU Guix. AB - In bioinformatics, as well as other computationally intensive research fields, there is a need for workflows that can reliably produce consistent output, from known sources, independent of the software environment or configuration settings of the machine on which they are executed. Indeed, this is essential for controlled comparison between different observations and for the wider dissemination of workflows. However, providing this type of reproducibility and traceability is often complicated by the need to accommodate the myriad dependencies included in a larger body of software, each of which generally comes in various versions. Moreover, in many fields (bioinformatics being a prime example), these versions are subject to continual change due to rapidly evolving technologies, further complicating problems related to reproducibility. Here, we propose a principled approach for building analysis pipelines and managing their dependencies with GNU Guix. As a case study to demonstrate the utility of our approach, we present a set of highly reproducible pipelines called PiGx for the analysis of RNA sequencing, chromatin immunoprecipitation sequencing, bisulfite treated DNA sequencing, and single-cell resolution RNA sequencing. All pipelines process raw experimental data and generate reports containing publication-ready plots and figures, with interactive report elements and standard observables. Users may install these highly reproducible packages and apply them to their own datasets without any special computational expertise beyond the use of the command line. We hope such a toolkit will provide immediate benefit to laboratory workers wishing to process their own datasets or bioinformaticians seeking to automate all, or parts of, their analyses. In the long term, we hope our approach to reproducibility will serve as a blueprint for reproducible workflows in other areas. Our pipelines, along with their corresponding documentation and sample reports, are available at http://bioinformatics.mdc-berlin.de/pigx. PMID- 30277500 TI - Six-monthly versus annual influenza vaccination in older adults in the tropics: an observer-blind, active-comparator controlled, randomised superiority trial. AB - Background: Antibody titres and vaccine effectiveness decline within six months after influenza vaccination in older adults. Biannual vaccination may be necessary to provide year-round protection in the tropics where influenza circulates throughout the year. Methods: Tropical Influenza Control Strategies (TROPICS1) was a single-centre, 1:1 randomised, observer-blinded, active comparator controlled, superiority study in 200 community-resident adults aged >=65 years. Participants received standard-dose trivalent inactivated influenza vaccination (IIV3) at enrolment, and either tetanus-diphtheria-pertussis vaccination or IIV3 six months later. Primary outcome was the proportion of participants with haemagglutination-inhibition (HI) geometric mean titre (GMT) >=1:40 one month after the second vaccination (Month 7). Secondary outcomes included GMTs to Month 12, the incidence of influenza-like illness (ILI), and adverse reactions after vaccination. Results: At Month 7, the proportion of participants with a HI tire >=1:40 against A/H1N1 increased by 21.4% (95% CI 8.6 33.4) in the six-monthly vaccination group. This proportion was not significantly higher for A/H3N2 (4.3, 95% CI -1.1-10.8) or B (2.1, 95% CI -2.0-7.3). Six monthly vaccination significantly increased GMTs against A/H1N1 and A/H3N2 at Month 7, but not B. Participants receiving repeat IIV3 reported a significantly lower incidence of ILI in the six months after the second vaccination (relative vaccine effectiveness 57.1%, 95% CI 0.6-81.5). The frequency of adverse events was similar after first or second influenza vaccination. PMID- 30277502 TI - Radiotherapy improves the survival of patients with metastatic esophageal squamous cell carcinoma: a propensity score matched analysis of Surveillance, Epidemiology, and End Results database. AB - The survival advantage of radiotherapy (RT) for patients with metastatic esophagus cancer has not been adequately evaluated. This study aims to find out the role of RT for metastatic esophagus cancer and to find the different effect for RT to esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC). This study included 5,970 metastatic esophagus cancer patients from the Surveillance, Epidemiology, and End Results (SEER) database, registered from January 2004 to December 2013. Propensity score (PS) analysis with 1:1 nearest neighbor matching method was used to ensure well-balanced characteristics of all comparison groups by histological types. The Kaplan-Meier and Cox proportional hazardous models were used to evaluate the overall survival (OS), cancer-specific survival (CSS), and corresponding 95% confidence interval (CI). Generally speaking, EAC did not get survival benefit from RT (median OS for RT group vs. no RT group-8.0, 7.6-8.4 vs. 9.0, 8.5-9.5, P = 0.073), whereas RT for metastatic ESCC did significantly improve OS (median OS for RT group vs. no-RT group-8.0, 7.4-8.6 vs. 7.0, 6.4-7.6, P = 0.044). Therefore, compared with adenocarcinoma, ESCC could get more survival benefit from RT. PMID- 30277503 TI - Bt Resistance Implications for Helicoverpa zea (Lepidoptera: Noctuidae) Insecticide Resistance Management in the United States. AB - Both maize and cotton genetically engineered to express Bt toxins are widely planted and important pest management tools in the United States. Recently, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae) has developed resistance to two toxin Bt maize and cotton (Cry1A and Cry2A). Hence, growers are transitioning to three toxin Bt cotton and maize that express both Cry toxins and the Vip3Aa toxin. H. zea susceptibility to Vip3Aa is threatened by 1) a lack of availability of non-Bt refuge crop hosts, including a 1-5% annual decline in the number of non Bt maize hybrids being marketed; 2) the ineffectiveness of three toxin cultivars to function as pyramids in some regions, with resistance to two out of three toxins in the pyramid; and 3) the lack of a high dose Vip3Aa event in cotton and maize. We propose that data should be collected on current Cry-resistant H. zea in the field to inform future Bt resistance models and that the deployment of Bt toxins and non-Bt refuge crops should be adjusted to favor susceptibility of H. zea to Bt toxins such as Vip3Aa. Finally, maize growers should be incentivized to plant non-Bt structured refuge and have access to hybrids with high-yielding genetic potential at a reasonable price. PMID- 30277499 TI - MetaPGN: a pipeline for construction and graphical visualization of annotated pangenome networks. AB - Pangenome analyses facilitate the interpretation of genetic diversity and evolutionary history of a taxon. However, there is an urgent and unmet need to develop new tools for advanced pangenome construction and visualization, especially for metagenomic data. Here, we present an integrated pipeline, named MetaPGN, for construction and graphical visualization of pangenome networks from either microbial genomes or metagenomes. Given either isolated genomes or metagenomic assemblies coupled with a reference genome of the targeted taxon, MetaPGN generates a pangenome in a topological network, consisting of genes (nodes) and gene-gene genomic adjacencies (edges) of which biological information can be easily updated and retrieved. MetaPGN also includes a self-developed Cytoscape plugin for layout of and interaction with the resulting pangenome network, providing an intuitive and interactive interface for full exploration of genetic diversity. We demonstrate the utility of MetaPGN by constructing Escherichia coli pangenome networks from five E. coli pathogenic strains and 760 human gut microbiomes,revealing extensive genetic diversity of E. coli within both isolates and gut microbial populations. With the ability to extract and visualize gene contents and gene-gene physical adjacencies of a specific taxon from large-scale metagenomic data, MetaPGN provides advantages in expanding pangenome analysis to uncultured microbial taxa. PMID- 30277501 TI - ESR2 Is Essential for Gonadotropin-Induced Kiss1 Expression in Granulosa Cells. AB - Hypothalamic expression of Kiss1 plays an essential role in the onset of puberty, gonadal development, and ovulation. Estrogens regulate the expression of Kiss1 in the hypothalamus through estrogen receptor-alpha. Kiss1 is also expressed in the ovary, where its expression correlates with the onset of puberty and progression of the estrous cycle. To date, estrogen regulation of Kiss1 expression in the ovary has not been investigated. We recently observed that gonadotropin-induced Kiss1 expression was absent in Esr2-null rat ovaries even though Esr1 was present. Wild-type granulosa cells abundantly expressed Kiss1 and oocytes expressed the Kiss1 receptor. We characterized estrogen receptor-beta (ESR2) regulation of Kiss1 expression in granulosa cells by identifying granulosa cell specific transcript variants and potential regulatory regions. The Kiss1 promoter, an upstream enhancer, and a downstream enhancer all possessed conserved estrogen response elements (EREs) and showed active histone marks in gonadotropin stimulated granulosa cells. The transcriptionally active Kiss1 promoter, as well as the enhancers, also revealed enrichment for ESR2 binding. Furthermore, activity of a Kiss1 promoter construct was induced after overexpression of ESR2 and was blocked upon mutation of an ERE within the promoter. Finally, pregnant mare serum gonadotropin and human chorionic gonadotropin administration induced phosphorylation of ESR2 and upregulated the AP-1 proteins FOSL2 and JUNB in granulosa cells. Activated MAPK ERK2 was associated with the ESR2 phosphorylation in granulosa cells, and AP-1 factors could synergistically activate the Kiss1 promoter activity. These gonadotropin-induced changes paralleled Kiss1 expression in granulosa cells. We conclude that gonadotropin-stimulated Kiss1 expression in granulosa cells is dependent on both the activation of ESR2 and the upregulation of AP-1. PMID- 30277506 TI - Ectoparasitic Mites Varroa underwoodi (Acarina: Varroidae) in Eastern Honeybees, but not in Western Honeybees. AB - The ectoparasitic mite Varroa destructor Anderson and Trueman (Acarina: Varroidae) shifted host from Eastern honeybees Apis cerana Fabricius (Hymenoptera: Apidae) to Western honeybees Apis mellifera Linnaeus (Hymenoptera: Apidae) with disastrous consequences globally. The high genetic diversity of V. destructor and abundant opportunities for cross-species transmission probably promoted this host shift. Whether Varroa underwoodi (Acarina: Varroidae) also exhibits these traits is unknown. Here, we conduct a large-scale survey across China on the occurrence, morphology, reproduction, and genetics of V. underwoodi in A. cerana and A. mellifera colonies to fill gaps in our knowledge of this mite and to determine whether host shifts occurred. Despite the large number of colonies screened, V. underwoodi was exclusively found in A. cerana, where it occurred at low infestation rates. Three genetic clades were detected in the V. underwoodi population, which differed neither in morphology nor in reproductive ability. Nevertheless, the genetic diversity of V. underwoodi is likely to increase chances for host shifts, even though opportunities for cross-species transmission seem low. More studies of the neglected Varroa species seem appropriate to enable a better understanding of host shifts in the Apis spp./Varroa spp. system and evaluate the potential risk they pose to apiculture with A. mellifera. PMID- 30277504 TI - Expression profile of miR-17/92 cluster is predictive of treatment response in rectal cancer. AB - MicroRNA (miRNA) profiling represents a promising source of cancer-related biomarkers. miRNA signatures are specific for each cancer type and subgroups of patients with diverse treatment sensitivity. Yet this miRNA potential has not been satisfactorily explored in rectal cancer (RC). The aim of the study was to identify the specific miRNA signature with clinical and therapeutic relevance for RC. Expressions of 2555 miRNA were examined in 20 pairs of rectal tumors and matched non-malignant tissues by 3D-Gene Toray microarray. Candidate miRNAs were validated in an independent cohort of 100 paired rectal tissues and in whole plasma and exosomes of 100 RC patients. To study the association of miRNA profile with therapeutic outcomes, plasma samples were taken repeatedly over a time period of 1 year reflecting thus patients' treatment responses. Finally, the most prominent miRNAs were investigated in vitro for their involvement in cell growth. We identified RC-specific miRNA signature that distinguishes responders from non responders to adjuvant chemotherapy. A predominant part of identified miRNAs was represented by the members of miR-17/92 cluster. Upregulation of miRNA-17, -18a, 18b, -19a, -19b, -20a, -20b and -106a in tumor was associated with higher risk of tumor relapse and their overexpression in RC cell lines stimulated cellular proliferation. Examination of these miRNAs in plasma exosomes showed that their levels differed between RC patients and healthy controls and correlated with patient's treatment response. miRNAs from miR-17/92 cluster represent a non invasive biomarker to predict posttreatment prognosis in RC patients. PMID- 30277505 TI - Emerging resistance to empiric antimicrobial regimens for pediatric bloodstream infections in Malawi (1998-2017). AB - Background: The adequacy of the WHO Integrated Management of Childhood Illness (IMCI) antimicrobial guidelines for the treatment of suspected severe bacterial infections is dependent on a low prevalence of antimicrobial resistance (AMR). We describe trends in etiologies and susceptibility patterns of bloodstream infections (BSI) in hospitalized children in Malawi. Methods: We determined the change in population-based incidence of BSI in children admitted to Queen Elizabeth Central Hospital, Blantyre, Malawi (1998-2017). AMR profiles were assessed by the disc diffusion method and trends over time were evaluated. Results: A total 89,643 pediatric blood cultures were performed, and 10,621 pathogens were included in the analysis. Estimated minimum incidence rates of BSI for those <=5 years of age fell from a peak of 11.4 per 1,000 persons in 2002 to 3.4 per 1,000 persons in 2017. Over two decades, resistance of Gram-negative pathogens to all empiric first-line antimicrobials (ampicillin/penicillin, gentamicin, ceftriaxone) among children <=5 years increased from 3.4% to 30.2% (p<0.001). Among those <=60 days, AMR to all first-line antimicrobials increased from 7.0% to 67.7% (p<0.001). Among children <=5 years, Klebsiella spp. resistance to all first-line antimicrobial regimens increased from 5.9% to 93.7% (p<0.001). Conclusions: The incidence of BSI among hospitalized children has decreased substantially over the last 20 years, although gains have been offset by increases in Gram-negative pathogens resistant to all empiric first-line antimicrobials. There is an urgent need to address the broader challenge of adapting IMCI guidelines to the local setting in the face of rapidly expanding AMR in childhood BSI. PMID- 30277507 TI - Patient cardiovascular risk self-management: results from a randomized trial of motivational interviewing delivered by practice nurses. AB - Background: To enhance cardiovascular risk management and patients' self management, a tailored programme to improve cardiovascular risk management was tested in a randomized trial. The presented study concerned secondary analysis. Objectives: To explore the correlations of practice nurses' counselling skills at baseline on chronic illness care (measured with Patient Assessment of Chronic Illness Care questionnaire) and patients' self-management (assessed with Patient Activation Measure) at follow-up and to examine the effect of the tailored implementation programme on chronic illness care and patients' self-management. Methods: A two-arm cluster randomized trial was conducted in 34 general practices in the Netherlands. Counselling skills of practice nurses at baseline were abstracted from audio-taped consultations, which were assessed by Motivational Interviewing Treatment Integrity. Data of 2184 patients with established cardiovascular disease or at high cardiovascular risk were gathered at inclusion and at 6 months follow-up by a composite questionnaire. Multilevel regression analysis was applied, controlling for patient characteristics. Results: Counselling skills of practice nurses were not associated with chronic illness care and patients' self-management scores. At follow-up, patients in the intervention group experienced less chronic illness care and were less activated in disease management than patients in the control group. The most important predictors were patients' age, gender and education level. Conclusions: The logic model underlying the implementation programme needs to be reconsidered, because patient perceptions were neither influenced by nurses' counselling skills nor by other components of the implementation programme. PMID- 30277508 TI - Correction. PMID- 30277509 TI - The Insecticide Resistance Allele kdr-his has a Fitness Cost in the Absence of Insecticide Exposure. AB - House flies, Musca domestica L. (Diptera: Muscidae), are major pests at animal production facilities. Insecticides, particularly pyrethroids, have been used for control of house fly populations for more than 30 yr, but the evolution of resistance will likely jeopardize fly control efforts. A major mechanism of pyrethroid resistance in the house fly is target site insensitivity (due to mutations in the Voltage-sensitive sodium channel [Vssc]). Based on a survey of house fly populations in 2007 and 2008, the most common resistance allele at 2/3 of the states in the United States is kdr-his. This was unexpected given the relatively lower level of resistance this allele confers, and led to speculation that the kdr-his allele may have a minimal fitness cost in the absence of insecticide. The goal of this study was to evaluate the fitness cost of kdr-his by monitoring the changes in allele frequency over 15 generations in the absence of insecticide. In crosses with two different insecticide susceptible strains, we found that kdr-his had a significant fitness cost. The implications of these results to insecticide resistance monitoring and management are discussed. PMID- 30277510 TI - Editorial for Liver Cancer in Asia. PMID- 30277512 TI - Impact of Insecticide Seed Treatments and Foliar Insecticides on Aphid Infestations in Wheat, Incidence of Barley Yellow Dwarf, and Yield in West Tennessee. AB - Several species of aphids (Hemiptera: Aphididae) infesting wheat may reduce yield by the transmission of barley yellow dwarf (BYD). Neonicotinoid seed treatments and foliar application of insecticides are two common methods to control aphid infestations and reduce BYD. An analysis was carried out across 33 insecticide efficacy tests performed in west Tennessee during the last 11 yr to determine how insecticide seed treatments and/or a late-winter foliar insecticide application affected aphid populations, incidence of BYD, and yield. A significant decrease in springtime aphid populations and incidence of BYD was observed when using a seed treatment, a foliar insecticide application, or both. Average wheat yields were increased by 280-381 kg/ha (5.3-7.2%) if an insecticide seed treatment was used or when a foliar insecticide application was made. Compared with insecticide seed treatments, average springtime aphid populations and the incidence of BYD were lower when a foliar insecticide was applied. A foliar insecticide application made in addition to insecticide seed treatments increased yield by an average of 196 kg/ha (3.4%). The yield increases over the nontreated control suggest that wheat growers in west Tennessee can use insecticides to manage aphids and prevent transmission of BYD. Consideration of environmental conditions, whether or not insecticide seed treatments were used, and scouting can be used to help make decisions on when or if to apply foliar insecticides. PMID- 30277511 TI - Enteric Fever Cases in the Two Largest Pediatric Hospitals of Bangladesh: 2013 2014. AB - Background: Enteric fever predominantly affects children in low- and middle income countries. This study examines the burden of enteric fever at the 2 pediatric hospitals in Dhaka, Bangladesh and assesses their capacity for inclusion in a prospective cohort study to support enteric fever prevention and control. Methods: A descriptive study of enteric fever was conducted among children admitted in 2013-2014 to inpatient departments of Dhaka Shishu and Shishu Shashthya Foundation Hospitals, sentinel hospitals of the World Health Organization-supported Invasive Bacterial Vaccine Preventable Disease surveillance platform. Results: Of 15917 children with blood specimens received by laboratories, 2.8% (443 of 15917) were culture positive for significant bacterial growth. Sixty-three percent (279 of 443) of these isolates were confirmed as the cases of enteric fever (241 Salmonella Typhi and 38 Salmonella Paratyphi A). In addition, 1591 children had suspected enteric fever. Overall, 3.6% (1870 of 51923) were laboratory confirmed or suspected enteric fever cases (55% male, median age 2 years, 86% from Dhaka district, median hospital stay 5 days). Conclusions: The burden of enteric fever among inpatients at 2 pediatric hospitals in Dhaka, Bangladesh is substantial. Therefore, inclusion of these hospitals in a prospective cohort study will be useful for the generation of credible disease burden estimates of enteric fever in Bangladesh. PMID- 30277513 TI - Neonicotinoid Insecticide Resistance in Tobacco Thrips (Thysanoptera: Thripidae) of Mississippi. AB - Insecticidal efficacy of neonicotinoid insecticides used against tobacco thrips, Frankliniella fusca (Hinds) (Thysanoptera: Thripidae), in cotton, Gossypium hirisutum L. (Malvales: Malvaceae), was evaluated for field populations collected in Mississippi during 2014-2016. Resistance was documented in 16 and 57% of populations to imidacloprid and thiamethoxam, respectively. Resistance levels did not vary by host plant for any neonicotinoid, but resistance levels varied between the two main agricultural areas (Delta and Hills) of Mississippi and among years for some neonicotinoids. In spite of documented resistance, neonicotinoid seed treatments are still used on cotton in the midsouthern United States due to the lack of reliable alternative management strategies. The development of alternative thrips management strategies is critical to the sustainability of cotton production in the midsouthern United States. PMID- 30277514 TI - Exercise for physical fitness, fatigue and quality of life of patients undergoing hematopoietic stem cell transplantation: a meta-analysis of randomized controlled trials. AB - Objectives: The objective of this meta-analysis is to systematically review the evidence on effects of exercise interventions in comparison to usual care with respect to physical fitness, fatigue, quality of life, anxiety and depression in hematopoietic stem cell transplantation patients for a hematological malignancies. And we are more focused on the optimal opportunity to exercise in hematopoietic stem cell transplantation recipients. Method: Databases were searched up to June 2018. We included randomized controlled trials comparing exercise with usual care in adult patients who had a hematologic malignancy. Standard mean differences were calculated and pooled to generate summary effect sizes and 95% confidence intervals. The Cochrane Collaboration Risk of Bias Tool was used to assess the methodological quality of the studies. Results: This meta analysis showed that exercise had a positive effect on lower muscle strength, fatigue and quality of life and had no effects on patients' cardiorespiratory fitness, upper muscle strength, psychosocial fitness and adverse events. Subgroup analysis showed that exercise had a favorable effect on upper/lower muscle strength, fatigue and quality of life when starting exercise pre-transplant, but exercise had no effects, except on quality of life when starting exercise after transplant. And patients in the pre-transplant exercise group did not exercise more graft vs host disease events nor deaths. Conclusion: Therefore, we can conclude that the optimal timing for the hematopoietic stem cell transplantation recipients to begin exercise training is before transplantation. PMID- 30277515 TI - psichomics: graphical application for alternative splicing quantification and analysis. AB - Alternative pre-mRNA splicing generates functionally distinct transcripts from the same gene and is involved in the control of multiple cellular processes, with its dysregulation being associated with a variety of pathologies. The advent of next-generation sequencing has enabled global studies of alternative splicing in different physiological and disease contexts. However, current bioinformatics tools for alternative splicing analysis from RNA-seq data are not user-friendly, disregard available exon-exon junction quantification or have limited downstream analysis features. To overcome such limitations, we have developed psichomics, an R package with an intuitive graphical interface for alternative splicing quantification and downstream dimensionality reduction, differential splicing and gene expression and survival analyses based on The Cancer Genome Atlas, the Genotype-Tissue Expression project, the Sequence Read Archive project and user provided data. These integrative analyses can also incorporate clinical and molecular sample-associated features. We successfully used psichomics in a laptop to reveal alternative splicing signatures specific to stage I breast cancer and associated novel putative prognostic factors. PMID- 30277516 TI - Identification of novel protein phosphatases as modifiers of alpha-synuclein aggregation in yeast. AB - Alpha-synuclein (aSyn) is a key player in a group of neurodegenerative diseases commonly known as synucleinopathies. Recent findings indicate phosphorylation in several aSyn residues can modulate its aggregation and subcellular localization, thereby affecting pathological processes. However, the precise molecular mechanisms governing aSyn phosphorylation are still unclear. Recent studies investigated the role of various families of protein kinases, such as the polo like kinases, G protein-coupled receptor kinases or casein kinases. In contrast, our understanding of the phosphatases involved in the dephosphorylation of aSyn is rather limited. Here, we exploited the unique toolbox of the yeast Saccharomyces cerevisiae in order to identify novel phosphatases capable of modulating aSyn phosphorylation, inclusion formation and toxicity of human aSyn. In summary, given the association between aSyn phosphorylation and pathology in Parkinson's disease and other synucleinopathies, modulation of this post translational modification may constitute an attractive target for therapeutic intervention. PMID- 30277517 TI - Environmental dimensions of antibiotic resistance: assessment of basic science gaps. AB - Antibiotic resistance is one of the major problems facing medical practice in the 21st century. Historical approaches to managing antibiotic resistance have often focused on individual patients, specific pathogens and particular resistance phenotypes. However, it is increasingly recognized that antibiotic resistance is a complex ecological and evolutionary problem. As such, understanding the dynamics of antibiotic resistance requires integration of data on the diverse mobile genetic elements often associated with antibiotic resistance genes, and their dissemination by various mechanisms of horizontal gene transfer between bacterial cells and environments. Most important is understanding the fate and effects of antibiotics at sub-inhibitory concentrations, and co-selection. This opinion paper identifies key knowledge gaps in our understanding of resistance phenomena, and outlines research needs that should be addressed to help us manage resistance into the future. PMID- 30277518 TI - The role of yeast ARO8, ARO9 and ARO10 genes in the biosynthesis of 3 (methylthio)-1-propanol from L-methionine during fermentation in synthetic grape medium. AB - 3-(Methylthio)-1-propanol (methionol), produced by yeast as an end-product of L methionine (L-Met) catabolism, imparts off-odours reminiscent of cauliflower and potato to wine. Saccharomyces cerevisiae ARO genes, including transaminases Aro8p and Aro9p, and decarboxylase Aro10p, catalyse two key steps forming methionol via the Ehrlich pathway. We compared methionol concentrations in wines fermented by single Deltaaro8, Deltaaro9, and Deltaaro10 deletants in lab strain BY4743 versus wine strain Zymaflore F15, and F15 double- and triple-aro deletants versus single aro deletants, using headspace-solid phase microextraction coupled with gas chromatography-mass spectrometry (HS-SPME/GC-MS).Deletion of two or more aro genes increased growth lag phase, with the greatest delay exhibited by F15 Deltaaro8 Deltaaro9. The single Deltaaro8 deletion decreased methionol by 44% in BY4743 and 92% in F15, while the Deltaaro9 deletion increased methionol by 46% in F15 but not BY4743. Single deletion of Deltaaro10 had no effect on methionol.Unexpectedly, F15 Deltaaro8 Deltaaro9 and F15 Deltaaro8 Deltaaro9 Deltaaro10 produced more methionol than F15 Deltaaro8. In the absence of Aro8p and Aro9p, other transaminases may compensate or an alternative pathway may convert methanethiol to methionol. Our results confirm that Ehrlich pathway genes differ greatly between lab and wine yeast strains, impacting downstream products such as methionol. PMID- 30277519 TI - Final report of survival and late toxicities in the Phase I study of stereotactic body radiation therapy for peripheral T2N0M0 non-small cell lung cancer (JCOG0702). AB - Purpose: A dose escalation study to determine the recommended dose with stereotactic body radiation therapy (SBRT) for peripheral T2N0M0 non-small cell carcinomas (JCOG0702) was conducted. The purpose of this paper is to report the survival and the late toxicities of JCOG0702. Materials and methods: The continual reassessment method was used to determine the dose level that patients should be assigned to and to estimate the maximum tolerated dose. The starting dose was 40 Gy in four fractions at D95 of PTV. Results: Twenty-eight patients were enrolled. Ten patients were treated with 40 Gy at D95 of PTV, four patients with 45 Gy, eight patients with 50 Gy, one patient with 55 Gy and five patients with 60 Gy. Ten patients were alive at the last follow-up. Overall survival (OS) for all patients was 67.9% (95% CI 47.3-81.8%) at 3 years and 40.8% (95% CI 22.4 58.5%) at 5 years. No Grade 3 or higher toxicity was observed after 181 days from the beginning of the SBRT. Compared to the toxicities up to 180 days, chest wall related toxicities were more frequent after 181 days. Conclusions: The 5-year OS of 40.8% indicates the possibility that SBRT for peripheral T2N0M0 non-small cell lung cancer is superior to conventional radiotherapy. The effect of the SBRT dose escalation on OS is unclear and further studies are warranted. PMID- 30277520 TI - Stacking-induced fluorescence increase reveals allosteric interactions through DNA. AB - From gene expression to nanotechnology, understanding and controlling DNA requires a detailed knowledge of its higher order structure and dynamics. Here we take advantage of the environment-sensitive photoisomerization of cyanine dyes to probe local and global changes in DNA structure. We report that a covalently attached Cy3 dye undergoes strong enhancement of fluorescence intensity and lifetime when stacked in a nick, gap or overhang region in duplex DNA. This is used to probe hybridization dynamics of a DNA hairpin down to the single-molecule level. We also show that varying the position of a single abasic site up to 20 base pairs away modulates the dye-DNA interaction, indicative of through-backbone allosteric interactions. The phenomenon of stacking-induced fluorescence increase (SIFI) should find widespread use in the study of the structure, dynamics and reactivity of nucleic acids. PMID- 30277521 TI - New revisions and current issues in the eighth edition of the TNM classification for non-small cell lung cancer. AB - In the eighth edition of the TNM classification of lung cancer, the prognostic impact of tumor size is emphasized as a descriptor of all T categories. Especially in lung cancer where tumor size is 5 cm or less, the 1-cm cutoff point significantly differentiated the survival outcome. In addition, the new staging categories were assigned, namely, Tis (adenocarcinoma in situ) and T1mi (minimally invasive adenocarcinoma). Furthermore, the measurement of a radiological solid component size excluding the ground glass opacity component or pathological invasive size without a lepidic component was proposed for deciding the cT/pT categories for lung adenocarcinoma. The N descriptors were kept the same as in the eventh edition on the whole, however, quantification of nodal disease had a prognostic impact based on the number of nodal stations involved in the eighth edition, i.e. N1a as a single N1 station, N1b as a multiple N1 station, N2a1 as a single N2 station without N1 (skip metastasis), N2a2 as a single N2 station with N1 disease, and N2b as a multiple N2 station. In the M descriptors, subclassification was performed based on the location or numbers of distantly metastatic lesions, i.e. M1a as any intrathoracic metastases, M1b as a single distant metastatic lesion in one organ, and M1c as multiple distant metastases in either a single organ or multiple organs. Survival analysis of the eighth edition of the TNM classification clearly separated the distinct groups, however, unsolved issues still remain that should be discussed and further revised for the forthcoming TNM staging system. PMID- 30277523 TI - Repellency and Laboratory Performance of Selected Insecticides to Field-Collected Insecticide Resistant German Cockroaches (Blattodea: Ectobiidae). AB - German cockroaches, Blattella germanica (L.) (Blattodea: Ectobiidae), are important indoor insect pests and remain difficult to control because of their ability to develop resistance to insecticides. The toxicity, resistance levels, repellency, and performance index (PI) value of five formulated insecticides (permethrin, chlorpyrifos, propoxur, imidacloprid, and fipronil) were determined for adult males of seven strains of the German cockroach: a laboratory-reared susceptible strain (S) and six field-collected strains (B, D, E, G, H, and I). Propoxur was generally the most toxic insecticide to all strains using continuous exposure methods; however, using Ebeling choice box methods, chlorpyrifos, and fipronil were most toxic. In both continuous exposure and Ebeling choice box tests, the field-collected strains were generally most resistant to permethrin among the five insecticides. The greatest increase in resistance ratios between the two exposure methods was for permethrin and propoxur. Permethrin was the most repellent insecticide against all but two strains (D and H). PI values reached 100 (no repellency and complete mortality) for the susceptible strain against only chlorpyrifos and fipronil. Only fipronil resulted in a PI value of 100 for any of the field-collected strains. Continuous exposure and Ebeling choice box resistance ratios were correlated, and both were correlated with previously reported resistance ratios (based on LD50 values). Choice box repellency, however, was only correlated with LD50 resistance ratios. PIMax was negatively correlated with all measures of resistance ratios. PMID- 30277524 TI - Parental tobacco use and child death: analysis of data from demographic and health surveys from South and South East Asian countries. AB - Background: Child mortality is a public health challenge in developing countries, and exposure to second-hand smoke and prenatal exposure to smokeless tobacco are risk factors for child death. We determined the associations between parental tobacco use and child death under the age of five in eight South and South East Asian countries. Methods: We analysed cross-sectional demographic and health survey data collected between 2005 and 2016, using multiple logistic regressions to estimate the unadjusted and adjusted associations between parental tobacco use and child death, accounting for demographic and economic covariates. Results: Overall prevalence of tobacco smoking was 46.8% for fathers and 2.7% for mothers, smokeless tobacco use was 32.6% for fathers and 7.8% for mothers and any tobacco use was 67.1% for fathers and 10.1% for mothers. Adjusted for demographic and economic covariates, child death was significantly associated with fathers' [odds ratio: 1.10; 95% confidence interval (CI): 1.03, 1.17] and mothers' (1.44; 1.23, 1.70) smoking tobacco, fathers' (1.25; 1.17, 1.34) and mothers' (1.11; 1.00, 1.23) use of smokeless tobacco and fathers' (1.21; 1.13, 1.29) and mothers' (1.24; 1.12, 1.36) use of any tobacco. Conclusions: Both smoked tobacco and smokeless tobacco policies should be aggressively implemented in public places and workplaces in developing countries, because they stimulate voluntary smoke and smokeless tobacco-free policies in homes. PMID- 30277522 TI - NMR structure of a G-quadruplex formed by four d(G4C2) repeats: insights into structural polymorphism. AB - Most frequent genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), is a largely increased number of d(G4C2)n*(G2C4)n repeats located in the non-coding region of C9orf72 gene. Non-canonical structures, including G-quadruplexes, formed within expanded repeats have been proposed to drive repeat expansion and pathogenesis of ALS and FTD. Oligonucleotide d[(G4C2)3G4], which represents the shortest oligonucleotide model of d(G4C2) repeats with the ability to form a unimolecular G-quadruplex, forms two major G-quadruplex structures in addition to several minor species which coexist in solution with K+ ions. Herein, we used solution-state NMR to determine the high-resolution structure of one of the major G-quadruplex species adopted by d[(G4C2)3G4]. Structural characterization of the G-quadruplex named AQU was facilitated by a single substitution of dG with 8Br-dG at position 21 and revealed an antiparallel fold composed of four G-quartets and three lateral C-C loops. The G-quadruplex exhibits high thermal stability and is favored kinetically and under slightly acidic conditions. An unusual structural element distinct from a C-quartet is observed in the structure. Two C*C base pairs are stacked on the nearby G-quartet and are involved in a dynamic equilibrium between symmetric N3-amino and carbonyl-amino geometries and protonated C+*C state.

AB - Background: Early exposure to socioeconomic disadvantage is associated with obesity. Here we investigated how early, and conducted mediation analyses to identify behavioural factors in adulthood that could explain why. Methods: Among 931 participants in the New England Family Study, we investigated the associations of family socioeconomic disadvantage measured before birth and at age 7 years with the following measures of adiposity in mid-adulthood (mean age = 44.4 years): body mass index (BMI), waist circumference and, among 400 participants, body composition from dual-energy X-ray absorption scans. Results: In linear regressions adjusting for age, sex, race and childhood BMI Z-score, participants in the highest tertile of socioeconomic disadvantage at birth had 2.6 additional BMI units in adulthood [95% confidence interval (CI) = 1.26, 3.96], 5.62 cm waist circumference (95% CI = 2.69, 8.55), 0.73 kg of android fat mass (95% CI = 0.25, 1.21), and 7.65 higher Fat Mass Index (95% CI = 2.22, 13.09). Conditional on disadvantage at birth, socioeconomic disadvantage at age 7 years was not associated with adult adiposity. In mediation analyses, 10-20% of these associations were explained by educational attainment and 5-10% were explained by depressive symptoms. Conclusions: Infancy may be a sensitive period for exposure to socioeconomic disadvantage, as exposure in the earliest years of life confers a larger risk for overall and central adiposity in mid-adulthood than exposure during childhood. Intervention on these two adult risk factors for adiposity would, if all model assumptions were satisfied, only remediate up to one-fifth of the excess adult adiposity among individuals born into socioeconomically disadvantaged households. PMID- 30277526 TI - Loss of MeCP2 in immature neurons leads to impaired network integration. AB - Rett syndrome (RTT) is a neurodevelopmental disorder caused by mutations or deletions in Methyl-CpG-binding Protein 2 (MeCP2), a brain-enriched transcriptional regulator. MeCP2 is highly expressed during neuronal maturation and its deficiency results in impaired dendritic morphogenesis and reduced dendritic spine numbers in developing neurons. However, whether MeCP2 deficiency impacts the integration of new neurons has not been directly assessed. In this study, we developed a modified rabies virus-mediated monosynaptic retrograde tracing method to interrogate presynaptic integration of MeCP2-deficent new neurons born in the adult hippocampus, a region with lifelong neurogenesis and plasticity. We found that selective deletion of MeCP2 in adult-born new neurons impaired their long-range connectivity to the cortex, whereas their connectivity within the local hippocampal circuits or with subcortical regions was not significantly affected. We further showed that knockdown of MeCP2 in primary hippocampal neurons also resulted in reduced network integration. Interestingly, (1-3) IGF-1, a small peptide under clinical trial testing for RTT, rescued neuronal integration deficits of MeCP2-deficient neurons in vitro but not in vivo. In addition, (1-3) IGF treatment corrected aberrant excitability and network synchrony of MeCP2-deficient hippocampal neurons. Our results indicate that MeCP2 is essential for immature neurons to establish appropriate network connectivity. PMID- 30277527 TI - Letter to the Editor. PMID- 30277528 TI - Effects of Pollination by the Indo-Malaya Stingless Bee (Hymenoptera: Apidae) on the Quality of Greenhouse-Produced Rockmelon. AB - Rockmelon (Cucumis melo Linnaeus (Cucurbitales: Cucurbitaceae)) is a novel commercialized fruit in Malaysia and has great potential to become an important horticultural crop for the international market. In this study, we investigated the effects of pollination by the Indo-Malaya stingless bee Heterotrigona itama Smith (Hymenoptera: Apidae) on measures of yield and quality of rockmelon cultivated in the greenhouse, compared with hand cross-pollination and self pollination. Results showed that rockmelon produced from plants pollinated by stingless bees and hand cross-pollination had higher fruit set, were heavier and larger, and contained higher numbers of seed per fruit compared with those produced by self-pollination. Pollination by stingless bees produced fruit with greater sweetness than either hand cross-pollination or self-pollination. This study demonstrated that stingless bee pollination produced rockmelon fruit of similar quality, but better yields compared to the other pollination treatments. We showed that stingless bees should be considered as an alternative, effective pollinator for the improved production of high quality rockmelon in commercial greenhouse cultivation.

AB - Background: Although the effects of individual-level factors on wellbeing change following work exit have been identified, the role of welfare-state variables at the country level has yet to be investigated. Methods: Data on 8037 respondents aged 50 years and over in 16 European countries were drawn from the Survey of Health, Ageing and Retirement in Europe (SHARE) and the English Longitudinal Study of Ageing (ELSA). We employed multilevel models to assess determinants of change in wellbeing following work exit, using CASP-12 change scores. After adjusting for institutionally defined route and timing of work exit, in addition to other individual-level variables, we tested country-level variables including welfare-state regime and measures of disaggregated welfare spending to determine their associations with wellbeing change and the proportion of between-country variance explained. Results: Individuals whose exit from paid work was involuntary or diverged from the typical retirement age experienced declines in wellbeing. Country effects accounted for 7% of overall variance in wellbeing change. Individuals residing in countries with a Mediterranean welfare regime experienced more negative changes in wellbeing, with a difference of -2.15 ( 3.23, -1.06) CASP-12 points compared with those in Bismarckian welfare states. Welfare regime explained 62% of between-country variance. National per-capita expenditure on non-healthcare in-kind benefits (services) was associated with more positive wellbeing outcomes. Conclusions: National expenditure on in-kind benefits, particularly non-healthcare services, is associated with more favourable wellbeing change outcomes following work exit in early old age. Welfare-state effects explain the majority of between-country differences in change in wellbeing. PMID- 30277530 TI - Response to Letter to the Editor. PMID- 30277531 TI - Laboratory and Field Assessments of Erythritol Derivatives on the Survival, Reproductive Rate, and Control of Drosophila suzukii (Diptera: Drosophilidae). AB - Spotted-wing Drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is a vinegar fly introduced unintentionally into the United States. Since 2008, D. suzukii has reduced annual berry yields from 6 to 100%. Effective control of D. suzukii during harvest requires weekly applications of low-residual, broad spectrum insecticides that are unavailable for organic farming. A novel ingestible insecticide, a 4-carbon polyol, mesoerythritol (erythritol), was found to kill 75 to 100% of larval and adult D. suzukii. However, mesoerythritol, at effective concentrations (0.5-1.0M), may be cost-prohibitive. Therefore, we conducted laboratory tests to assess the effects of lower cost derivatives of erythritol, namely the pentaerythritol series of 1,3-diols on D. suzukii pupal production, adult production, adult mortality, brood output, and reproductive increase. We then selected the two most promising compounds for a field test on fruiting rabbiteye blueberry. From 90 to 100% of adults died when fed food moistened with 1M solutions of mesoerythritol and pentaerythritol. Mesoerythritol and dipentaerythritol at a concentration of 1M were ovicidal/larvicidal, killing >=85% of immatures. Overall, 1M mesoerythritol killed 80% or more larvae and adults, thus bringing populations to near zero. The heaviest compound of this series, tripentaerythritol, at all concentrations, was largely benign to both adults and immatures. Thus, we cannot recommend tripentaerythritol for D. suzukii control. In a blueberry field, 0.5M mesoerythritol and 0.5M pentaerythritol, each by themselves, reduced egg infestation by 64% and larval infestation by 93%; their combination (0.25M mesoerythritol and 0.25M pentaerythritol) achieved even greater egg control with 82% fewer eggs infesting blueberry fruits.

PMID- 30277533 TI - Association between early history of asthma and COPD diagnosis in later life: a systematic review and meta-analysis. AB - Background: Whereas most studies have reported prior history/diagnosis of asthma as an independent risk factor for chronic obstructive pulmonary disease (COPD) development in later life, no systematic review and meta-analysis has been conducted to synthesize these observational studies. The aim of this review is to investigate associations between prior history of asthma and later development of COPD. Methods: We conducted a comprehensive search in PubMed, CINAHL and EMBASE for studies related to prior history of asthma and COPD diagnosis. Articles were screened for relevance by two independent reviewers. Methodological quality was independently assessed and data extracted for qualitative and quantitative review. We explored heterogeneity and performed a publication bias check. Results: From the 1260 articles retrieved, 9 were included in the qualitative review and 7 in the meta-analysis. History of asthma was associated with developing COPD in later life (Inverse Variance Random-effects model, odds ratio: 7.87, 95% confidence interval: 5.40-11.45, p < 0.00001). Conclusions: Studies with high methodological quality provided sufficient evidence to suggest that individuals with previous history of asthma have an increasing likelihood of developing COPD in later life. PMID- 30277534 TI - Editorial: We need to talk about authorship. AB - In our day-to-day editorial work at GigaScience, time and again we see issues cropping up that make us worry whether everyone understands good scientific practice when it comes to listing author names on the title page. There are many issues that underlie inappropriate authorship designations, but there are also guidelines to help potential authors determine when and how a researcher should be included with a manuscript. Here, we help clarify this and also provide a clear statement of our expectations around how authors are assigned to manuscripts submitted to GigaScience. PMID- 30277535 TI - Disentangling Within- and Between-Person Effects of Shared Risk Factors on E cigarette and Cigarette Use Trajectories From Late Adolescence to Young Adulthood. AB - Background: Longitudinal studies report associations between use of electronic cigarettes (ECs) and cigarettes over time among young people, but do not distinguish within- from between-person effects, which complicates interpretation of findings. Further, the role of shared risk factors, such as substance use and mental health, in explaining longitudinal associations between EC and cigarette use remains unclear. This study used within- and between-person analyses to assess longitudinal associations between youths' EC and cigarette use and shared risk factors. Methods: Between 2015 and 2017, 2039 youths completed three Web based surveys, allowing us to model EC and cigarette use from ages 16 to 20. Auto regressive latent growth models with structured residuals (ALT-SR) examined both between-person and within-person associations between past-month frequency of EC use, cigarette use, and third variables (alcohol and marijuana use, mental health symptoms) over time. Results: Models revealed robust reciprocal associations between EC and cigarette use, such that more frequent EC use at one time predicted more frequent cigarette use at the subsequent time, and vice versa. Between-person analyses showed associations between shared risk factors and both EC and cigarette use. However, shared risk factors did not predict frequency of subsequent EC and cigarette use in within-person analyses. Conclusions: Findings add to a growing body of research suggesting that EC use among youth is prospectively associated with progression toward greater cigarette use. Shared risk factors may help explain differences in EC and cigarette use patterns between young people, but do not appear to influence longitudinal trajectories of EC and cigarette use within individuals. Implications: This study examined within and between-person associations between e-cigarette use, cigarette use, and shared risk factors (alcohol use, marijuana use, mental health symptoms) in a longitudinal cohort of youths. Within- and between-person analyses revealed reciprocal prospective associations between e-cigarette and cigarette use, suggesting a progression toward more frequent use of both products over time. The shared risk factors examined here did not affect escalations in e-cigarette or cigarette use over time within individuals, but likely influence which youths use these products. Findings add to a growing body of evidence suggesting that e cigarette use increases subsequent cigarette use in young people. PMID- 30277536 TI - Combined Iron Oxide Nanoparticle Ferumoxytol and Gadolinium Contrast Enhanced MRI Defines Glioblastoma Pseudo-progression. AB - Background: Noninvasively differentiating therapy-induced pseudo-progression from recurrent disease in patients with glioblastoma is prospectively difficult due to the current lack of a biologically specific imaging metric. Ferumoxytol iron oxide nanoparticle MRI contrast characterizes innate immunity mediated neuroinflammation; therefore, we hypothesized that combined ferumoxytol and gadolinium enhanced MRI could serve as a biomarker of glioblastoma pseudo progression. Methods: In this institutional review board approved, retrospective study, we analyzed ferumoxytol and gadolinium contrast enhanced T1-weighted 3T MRI in 45 patients with glioblastoma over multiple clinical time points. IDH-1 mutational status was characterized by exome sequencing. Sum of products diameter measurements were calculated according to RANO criteria from both gadolinium and ferumoxytol enhanced sequences. Enhancement mismatch was calculated as the natural log of the ferumoxytol to gadolinium sum of products diameter ratio. Analysis of variance and Students t-test assessed differences in mismatch ratios. P-value < 0.05 indicated statistical significance. Results: With the development of pseudo-progression we observed a significantly elevated mismatch ratio when compared to disease recurrence (P< 0.01) within IDH-1 wild type patients. Patients with IDH-1 mutation demonstrated significantly reduced mismatch ratio with the development of pseudo-progression when compared to disease recurrence (P< 0.01). Receiver operator curve analysis demonstrated 100% sensitivity and specificity for the use of mismatch ratios as a diagnostic biomarker of pseudo progression. Conclusion: Our study suggests that ferumoxytol to gadolinium contrast mismatch ratios are a MRI biomarker for the diagnosis of pseudo progression in patients with glioblastoma. This may be due to the unique characterization of therapy-induced neuroinflammation. PMID- 30277538 TI - N2M2 (NOA20) phase I/II trial of molecularly matched targeted therapies plus radiotherapy in patients with newly diagnosed non-MGMT hypermethylated glioblastoma. AB - Background: Patients with glioblastoma without O6-methyl guanine O6 methylatransferase (MGMT) promoter hypermethylation are unlikely to benefit from alkylating chemotherapy with temozolomide (TMZ). Trials aiming at replacing TMZ with targeted agents in unselected patient populations have failed to demonstrate any improvement of survival. Advances in molecular understanding and diagnostic precision enable identification of key genetic alterations in a timely manner and in principle allow treatments with targeted compounds based on molecular markers. Methods and analysis: The NCT Neuro Master Match (N2M2) trial is an open label multicenter phase I/IIa umbrella trial for patients with newly diagnosed isocitrate dehydrogenase (IDH) wildtype glioblastoma without MGMT promoter hypermethylation to show safety, feasibility and preliminary efficacy of treatment with targeted compounds in addition to standard radiotherapy based on molecular characterization. N2M2 is formally divided in a DISCOVERY and a TREATMENT part. DISCOVERY includes broad molecular neuropathological diagnostics to detect predefined biomarkers for targeted treatments. Molecular diagnostics and bioinformatic evaluation are performed within four weeks, allowing a timely initiation of postoperative treatment. Stratification for TREATMENT takes place in five subtrials, including alectinib, idasanutlin, palbociclib, vismodegib and temsirolimus as targeted therapies, according to the best matching molecular alteration. Patients without matching alterations are randomized between subtrials without strong biomarkers using atezolizumab and asinercept (APG101), and the standard of care, TMZ. For the phase I parts, a Bayesian criterion is used for continuous monitoring of toxicity. In the phase II trials, progression free survival at six months is used as endpoint for efficacy. PMID- 30277540 TI - Nursing Education: Our Iceberg Is Melting. PMID- 30277537 TI - The bacterial Mre11-Rad50 homolog SbcCD cleaves opposing strands of DNA by two chemically distinct nuclease reactions. AB - The Mre11-Rad50 complex is a DNA double-strand break sensor that cleaves blocked DNA ends and hairpins by an ATP-dependent endo/exonuclease activity for subsequent repair. For that, Mre11-Rad50 complexes, including the Escherichia coli homolog SbcCD, can endonucleolytically cleave one or both strands near a protein block and process free DNA ends via a 3'-5' exonuclease, but a unified basis for these distinct activities is lacking. Here we analyzed DNA binding, ATPase and nuclease reactions on different DNA substrates. SbcCD clips terminal bases of both strands of the DNA end in the presence of ATPgammaS. It introduces a DNA double-strand break around 20-25 bp from a blocked end after multiple rounds of ATP hydrolysis in a reaction that correlates with local DNA meltability. Interestingly, we find that nuclease reactions on opposing strands are chemically distinct, leaving a 5' phosphate on one strand, but a 3' phosphate on the other strand. Collectively, our results identify an unexpected chemical variability of the nuclease, indicating that the complex is oriented at a free DNA end and facing a block with opposite polarity. This suggests a unified model for ATP-dependent endo- and exonuclease reactions at internal DNA near a block and at free DNA ends. PMID- 30277541 TI - Relationship of Multiple Attempts on an Admissions Examination to Early Program Performance. AB - BACKGROUND: When a student makes multiple attempts at an admissions assessment, an institution must decide how to incorporate the resulting information into its admissions decision. However, little research exists to guide this decision within a nursing admissions context. METHOD: This article examines patterns in retesting scores from a nursing admissions assessment and the correlations of four retesting score treatments with scores on an early program assessment. RESULTS: Although test scores do increase with each subsequent attempt, the average of all attempt scores is more highly correlated, in almost all instances, with future performance in a nursing program than any one test score. CONCLUSION: These results indicate that nursing programs presented with multiple scores from an examinee would be best served by using an average of all available scores when making admissions decisions.

AB - BACKGROUND: Nursing faculty plays a central role in facilitating service learning experiences, yet little is known about their perceptions of service-learning. METHOD: Whit-temore's and Knafl's method for integrative review was used to analyze sources from CINAHL, ERIC, MEDLINE Complete, ProQuest LLC, and ScienceDirect. RESULTS: Literature about nursing faculty perceptions of service learning was scarce. Therefore, a thematic analysis was completed on 17 diverse sources regarding general faculty perceptions. CONCLUSION: Limited research was discovered related to nursing faculty perceptions, exposing a gap in the literature. Further research may clarify the role of service-learning in nursing education.

AB - BACKGROUND: In the past decade, little research has been conducted regarding individuals' stories about not initially being successful on the National Council Licensure Examination for Registered Nurses. An unsuccessful licensure examination attempt may affect the individual personally and profoundly in ways that could influence their future success. METHOD: Individual in-depth interviews were conducted once with 15 RNs who were initially unsuccessful on the licensure examination and subsequently passed. Data analyses were conducted using both manual and electronic coding through thematic identification. Rigor was ensured by meeting quality criteria for qualitative research. RESULTS: Four themes were identified: (a) Pressures all Around, (b) the Stigma of Being Unsuccessful, (c) Correcting the Problems, and (d) Ultimate Triumph in Discovery. CONCLUSION: Following their initial unsuccessful National Council Licen-sure Examination for Registered Nurses results, participants were deeply affected, but after accepting help from family, friends, nursing instructors, and managers, they were able to move forward, change their approaches, and become RNs.

AB - BACKGROUND: The American Nurses Association recognizes the specialty practice of Clinical Research Nursing, but many new nurses are unaware of the specialty and lack knowledge to effectively interact with research teams. METHOD: Participants completed a novel online survey to describe the level of awareness and understanding of the clinical research nursing specialty and the effect of clinical studies on nursing practice in fourth-year baccalaureate nursing program students. RESULTS: Ninety-three participants completed the survey. Most were aware that some nurses specialize in the care of clinical study participants, and most did not know how to effectively support research teams. Years of nursing experience was associated with an understanding of how to effectively collaborate with clinical research nurses and an interest in a career as a clinical research nurse. CONCLUSION: Entry-level nursing programs should expose students to the clinical research nurse role and provide the knowledge needed to collaborate with researchers when caring for patients in clinical studies.

AB - BACKGROUND: Scant evidence is found in the literature regarding the unit-level Health Education Systems, Inc. (HESI) examinations. This study aims to (a) compare student Psych HESI examination scores between cohorts after increasing grade allocation from 5% to 15%, and (b) examine student perceptions of the impact of increasing the percentage of course grade allocation. METHOD: An ex post facto research design analyzed differences in Psych HESI examination scores. HESI examination mean score differences between groups were analyzed using ANOVA. Narrative responses were analyzed using content analysis. RESULTS: Psych HESI examination means increased from 836 in spring 2015 (5% of course grade) to 905 in fall 2015 (15% of course grade). Narrative response themes included (a) Validated Learning; (b) Compelled Participants to Study More; (c) Incongruent With Class Content and Preparation Books; and (d) Stress-Producing. CONCLUSION: HESI examination scores improved with increasing course grade percentage allocated to the HESI score. Students indicated positive and negative perceptions of the increased grade allocation. [J Nurs Educ. 2018;57(10):604-608.]. PMID- 30277546 TI - Comparison of Two Methods of Teaching Culture to Bachelor of Science in Nursing Students. AB - BACKGROUND: The nursing literature examining effective methods to teach transcultural self-efficacy demonstrates inconsistent findings. This study evaluated the effectiveness of a nursing stand-alone culture course with concurrent field experiences compared with the standard integrated culture content in the curriculum in increasing transcultural self-efficacy in nursing students. METHOD: This quasi-experimental, static-group comparison used the Transcultural Self-Efficacy Tool to measure outcomes. The treatment group consisted of first-semester nursing students (n = 53) enrolled in a pilot 2 credit culture course. The control group consisted of graduating senior nursing students (n = 19) who had culture integrated throughout the curriculum. RESULTS: The posttest of the first-semester students in the treatment group scored higher than either their pretest or the graduating senior students (control group). CONCLUSION: The stand-alone culture course had a greater positive effect than the integrated culture content on students' transcultural self-efficacy. [J Nurs Educ. 2018;57(10):609-613.]. PMID- 30277547 TI - Stereotype Threat in Male Nurse-Patient Interactions. AB - BACKGROUND: Stereotype threat describes the apprehension individuals experience from the prospect of confirming negative self-relevant stereotypes. Due to their minority status, male nurses are believed to be susceptible to stereotype threat effects in the field of nursing. METHOD: One hundred eighty-three male nursing students were randomly assigned to one of three evaluative frames (patient management, empathy, or control) and tasked with completing an online patient simulation experiment. With empathy serving as a form of stereotype threat, participant responses were analyzed for tentative language use. RESULTS: An interaction effect (patient gender * frame) was observed, where participants were most tentative when the simulation involved a male patient in the empathy frame. CONCLUSION: Findings from the study offer encouragement as the communicative abilities of participants were not consistently influenced under conditions of stereotype threat. This provides support for the need to forearm male nurses against the pernicious effects of gender-based stereotypes. [J Nurs Educ. 2018;57(10):614-619.].

AB - Background: In addition to the established association between general obesity and breast cancer risk, central obesity and circulating fasting insulin and glucose have been linked to the development of this common malignancy. Findings from previous studies, however, have been inconsistent, and the nature of the associations is unclear. Methods: We conducted Mendelian randomization analyses to evaluate the association of breast cancer risk, using genetic instruments, with fasting insulin, fasting glucose, 2-h glucose, body mass index (BMI) and BMI adjusted waist-hip-ratio (WHRadj BMI). We first confirmed the association of these instruments with type 2 diabetes risk in a large diabetes genome-wide association study consortium. We then investigated their associations with breast cancer risk using individual-level data obtained from 98 842 cases and 83 464 controls of European descent in the Breast Cancer Association Consortium. Results: All sets of instruments were associated with risk of type 2 diabetes. Associations with breast cancer risk were found for genetically predicted fasting insulin [odds ratio (OR) = 1.71 per standard deviation (SD) increase, 95% confidence interval (CI) = 1.26-2.31, p = 5.09 * 10-4], 2-h glucose (OR = 1.80 per SD increase, 95% CI = 1.3 0-2.49, p = 4.02 * 10-4), BMI (OR = 0.70 per 5-unit increase, 95% CI = 0.65-0.76, p = 5.05 * 10-19) and WHRadj BMI (OR = 0.85, 95% CI = 0.79-0.91, p = 9.22 * 10-6). Stratified analyses showed that genetically predicted fasting insulin was more closely related to risk of estrogen-receptor [ER]-positive cancer, whereas the associations with instruments of 2-h glucose, BMI and WHRadj BMI were consistent regardless of age, menopausal status, estrogen receptor status and family history of breast cancer. Conclusions: We confirmed the previously reported inverse association of genetically predicted BMI with breast cancer risk, and showed a positive association of genetically predicted fasting insulin and 2-h glucose and an inverse association of WHRadj BMI with breast cancer risk. Our study suggests that genetically determined obesity and glucose/insulin-related traits have an important role in the aetiology of breast cancer.

AB - BACKGROUND: The use of telehealth to provide care to millions of patients who have difficulty accessing care through traditional means is growing exponentially. Nurse educators must prepare students to meet the challenge of managing this mode of care delivery. METHOD: A simulated telehealth experience was designed using the International Nursing Association for Clinical Simulation and Learning Standards of Best Practice: SimulationTM, student learning objectives, and telehealth competencies. The design promoted active participation in a telehealth visit with a standardized patient. RESULTS: The simulation provided students with the opportunity to demonstrate use of telehealth equipment and become familiar with telehealth competencies. This hands-on experience increased student engagement related to telehealth as a health care delivery option and was an effective objective structured clinical examination. CONCLUSION: Integration of telehealth into the nursing curriculum is a necessity as health care technology advances. Simulation is one strategy available to expose students to telehealth and increase student engagement. [J Nurs Educ. 2018;57(10):624-627.].

PMID- 30277556 TI - Antihypertensive drug therapy for mild to moderate hypertension during pregnancy. AB - BACKGROUND: Antihypertensive drugs are often used in the belief that lowering blood pressure will prevent progression to more severe disease, and thereby improve pregnancy outcome. This Cochrane Review is an updated review, first published in 2001 and subsequently updated in 2007 and 2014. OBJECTIVES: To assess the effects of antihypertensive drug treatments for women with mild to moderate hypertension during pregnancy. SEARCH METHODS: We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (13 September 2017), and reference lists of retrieved studies. SELECTION CRITERIA: All randomised trials evaluating any antihypertensive drug treatment for mild to moderate hypertension during pregnancy, defined as systolic blood pressure 140 to 169 mmHg and/or diastolic blood pressure 90 to 109 mmHg. Comparisons were of one or more antihypertensive drug(s) with placebo, with no antihypertensive drug, or with another antihypertensive drug, and where treatment was planned to continue for at least seven days. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. MAIN RESULTS: For this update, we included 63 trials (data from 58 trials, 5909 women), with moderate to high risk of bias overall.We carried out GRADE assessments for the main 'antihypertensive drug versus placebo/no antihypertensive drug' comparison only. Evidence was graded from very low to moderate certainty, with downgrading mainly due to design limitations and imprecision.For many outcomes, trials contributing data evaluated different hypertensive drugs; while we did not downgrade for this indirectness, results should be interpreted with caution.Antihypertensive drug versus placebo/no antihypertensive drug (31 trials, 3485 women)Primary outcomes: moderate-certainty evidence suggests that use of antihypertensive drug(s) probably halves the risk of developing severe hypertension (risk ratio (RR) 0.49; 95% confidence interval (CI) 0.40 to 0.60; 20 trials, 2558 women), but may have little or no effect on the risk of proteinuria/pre-eclampsia (average risk ratio (aRR) 0.92; 95% CI 0.75 to 1.14; 23 trials, 2851 women; low-certainty evidence). Moderate-certainty evidence also shows that antihypertensive drug(s) probably have little or no effect in the risk of total reported fetal or neonatal death (including miscarriage) (aRR 0.72; 95% CI 0.50 to 1.04; 29 trials, 3365 women), small-for gestational-age babies (aRR 0.96; 95% CI 0.78 to 1.18; 21 trials, 2686 babies) or preterm birth less than 37 weeks (aRR 0.96; 95% CI 0.83 to 1.12; 15 trials, 2141 women). SECONDARY OUTCOMES: we are uncertain of the effect of antihypertensive drug(s) on the risk of maternal death, severe pre-eclampsia, or eclampsia, orimpaired long-term growth and development of the baby in infancy and childhood, because the certainty of this evidence is very low. There may be little or no effect on the risk of changed/stopped drugs due to maternal side-effects, or admission to neonatal or intensive care nursery (low-certainty evidence). There is probably little or no difference in the risk of elective delivery (moderate certainty evidence).Antihypertensive drug versus another antihypertensive drug (29 trials, 2774 women)Primary outcomes: beta blockers and calcium channel blockers together in the meta-analysis appear to be more effective than methyldopa in avoiding an episode of severe hypertension (RR 0.70; 95% CI 0.56 to 0.88; 11 trials, 638 women). There was also an increase in this risk when other antihypertensive drugs were compared with calcium channel blockers (RR 1.86; 95% CI 1.09 to 3.15; 5 trials, 223 women), but no evidence of a difference when methyldopa and calcium channel blockers together were compared with beta blockers (RR1.18, 95% CI 0.95 to 1.48; 10 trials, 692 women). No evidence of a difference in the risk of proteinuria/pre-eclampsia was found when alternative drugs were compared with methyldopa (aRR 0.78; 95% CI 0.58 to 1.06; 11 trials, 997 women), with calcium channel blockers (aRR: 1.24, 95% CI 0.70 to 2.19; 5 trials, 375 women), or with beta blockers (aRR 1.21, 95% CI 0.88 to 1.67; 12 trials, 1107 women).For the babies, we found no evidence of a difference in the risk oftotal reported fetal or neonatal death (including miscarriage) when comparing other antihypertensive drugs with methyldopa (aRR 0.77, 95% CI 0.52 to 1.14; 22 trials, 1791 babies), with calcium channel blockers (aRR 0.90, 95% CI 0.52 to 1.57; nine trials, 700 babies), or with beta blockers (aRR: 1.23, 95% CI 0.81 to 1.88; 19 trials, 1652 babies); nor in the risk for small-for-gestational age in the comparison with methyldopa (aRR 0.79, 95% CI 0.52 to 1.20; seven trials, 597 babies), with calcium channel blockers (aRR 1.05, 95% CI 0.64 to 1.73; four trials, 200 babies), or with beta blockers (average RR 1.13, 95% CI 0.80 to 1.60; 7 trials, 680 babies). No evidence of an overall difference among groups in the risk of preterm birth (less than 37 weeks) was found in the comparison with methyldopa (aRR: 0.91; 95% CI 0.68 to 1.22; 11 trials, 835 women), with calcium channel blockers (aRR 0.85, 95% CI 0.59 to 1.23; six trials, 330 women), or with beta blockers (aRR 1.22, 95% CI 0.90 to 1.66; 9 trials, 806 women). SECONDARY OUTCOMES: There were no cases of maternal death andeclampsia. There is no evidence of a difference in the risk of severe pre-eclampsia, changed/stopped drug due to maternal side-effects, elective delivery, admission to neonatal or intensive care nursery when other antihypertensive drugs are compared with methyldopa, calcium channel blockers or beta blockers. Impaired long-term growth and development in infancy and childhood was not reported for these comparisons. AUTHORS' CONCLUSIONS: Antihypertensive drug therapy for mild to moderate hypertension during pregnancy reduces the risk of severe hypertension. The effect on other clinically important outcomes remains unclear. If antihypertensive drugs are used, beta blockers and calcium channel blockers appear to be more effective than the alternatives for preventing severe hypertension. High-quality large sample-sized randomised controlled trials are required in order to provide reliable estimates of the benefits and adverse effects of antihypertensive treatment for mild to moderate hypertension for both mother and baby, as well as costs to the health services, women and their families.

AB - Colorectal cancer (CRC), the third most common cancer diagnosed in both men and women in the United States, shows a highly ineffective therapeutic management. In these years neither substantial improvements nor new therapeutic approaches have been provided to patients. Performing the early lead discovery phases of new cancer drugs in cellular models, resembling as far as possible the real in vivo tumor environment, may be more effective in predicting their future success in the later clinical phases. In this review, we critically describe the most representative bioengineered models for anticancer drug screening in CRC from the conventional two-dimensional models to the new-generation three-dimensional scaffold-based ones. The scaffold aims to replace the extracellular matrix, thus influencing the biomechanical, biochemical, and biological properties of cells and tissues. In this scenario, we believe that reconstitution of tumor condition is mandatory for an alternative in vitro methods to study cancer development and therapeutic strategies. PMID- 30277558 TI - Variation in the vital rates of an Antarctic marine predator: the role of individual heterogeneity. AB - Variation in life-history traits such as lifespan and lifetime reproductive output is thought to arise, in part, due to among-individual differences in the underlying probabilities of survival and reproduction. However, the stochastic nature of demographic processes can also generate considerable variation in fitness-related traits among otherwise-identical individuals. An improved understanding of life-history evolution and population dynamics therefore depends on evaluating the relative role of each of these processes. Here, we used a 33-yr data set with reproductive histories for 1,274 female Weddell seals from Erebus Bay, Antarctica, to assess the strength of evidence for among-individual heterogeneity in the probabilities of survival and reproduction, while accounting for multiple other sources of variation in vital rates. Our analysis used recent advances in Bayesian model selection techniques and diagnostics to directly compare model fit and predictive power between models that included individual effects on survival and reproduction to those that did not. We found strong evidence for costs of reproduction to both survival and future reproduction, with breeders having rates of survival and subsequent reproduction that were 3% and 6% lower than rates for non-breeders. We detected age-related changes in the rates of survival and reproduction, but the patterns differed for the two rates. Survival rates steadily declined from 0.92 at age 7 to 0.56 at the maximal age of 31 yr. In contrast, reproductive rates increased from 0.68 at age 7 to 0.79 at age 16 and then steadily declined to 0.37 for the oldest females. Models that included individual effects explained more variation in observed life histories and had better estimated predictive power than those that did not, indicating their importance in understanding sources of variation among individuals in life history traits. We found that among-individual heterogeneity in survival was small relative to that for reproduction. Our study, which found patterns of variation in vital rates that are consistent with a series of predictions from life-history theory, is the first to provide a thorough assessment of variation in important vital rates for a long-lived, high-latitude marine mammal while taking full advantage of recent developments in model evaluation.

PMID- 30277560 TI - Sample Selection for Medicare Risk Adjustment Due to Systematically Missing Data. AB - OBJECTIVE: To assess the issue of nonrepresentative sampling in Medicare Advantage (MA) risk adjustment. DATA SOURCES: Medicare enrollment and claims data from 2008 to 2011. DATA EXTRACTION: Risk adjustment predictor variables were created from 2008 to 2010 Part A and B claims and the Medicare Beneficiary Summary File. Spending is based on 2009-2011 Part A and B, Durable Medical Equipment, and Home Health Agency claims files. STUDY DESIGN: A propensity-score matched sample of Traditional Medicare (TM) beneficiaries who resembled MA enrollees was created. Risk adjustment formulas were estimated using multiple techniques, and performance was evaluated based on R2 , predictive ratios, and formula coefficients in the matched sample and a random sample of TM beneficiaries. PRINCIPAL FINDINGS: Matching improved balance on observables, but performance metrics were similar when comparing risk adjustment formula results fit on and evaluated in the matched sample versus fit on the random sample and evaluated in the matched sample. CONCLUSIONS: Fitting MA risk adjustment formulas on a random sample versus a matched sample yields little difference in MA plan payments. This does not rule out potential improvements via the matching method should reliable MA encounter data and additional variables become available for risk adjustment. PMID- 30277561 TI - The imbalance of Th17/Treg axis involved in the pathogenesis of preeclampsia. AB - PROBLEM: Inappropriate activation of the immune system, particularly the imbalance of T-helper type 17 (Th17)/regulatory T (Treg) cells is thought to play considerable roles in preeclampsia (PE). To investigate the probable effects of the adaptive immune system in the pathophysiology of PE, we analyzed the dynamic changes of Th17/Treg cells, cytokines profile, and transcription pattern of Th17/Treg-related genes and microRNAs (miRNAs) in 50 women suffering from PE in comparison with 50 healthy pregnant women. METHODS: Expressions of cytokines, specific transcription factors, and related miRNAs were measured by real-time polymerase chain reaction (PCR). Enzyme-linked immunosorbent assay (ELISA) was used to test the interleukin (IL)-17, IL-23, IL-6, and IL-10 and transforming growth factor beta in serum and supernatant of peripheral blood mononuclear cells (PBMCs). The frequency of Th17 and Treg cells were determined by flow cytometry. RESULTS: PE patients exhibited a decreased number of Treg cells (p = 0.006), while Th17 cells were increased ( p = 0.004). Forkhead box P3 and IL-10 mRNA expressions were reduced ( p = 0.0001 and 0.0028, respectively), while expressions of retinoic acid receptor-related orphan nuclear receptor gammat, IL 17, IL-23, and IL-6 were enhanced ( p < 0.0001, 0.0018, 0.0014, and 0.027, respectively). ELISA results also showed increased levels of IL-6, IL-17, and IL 23 ( p = 0.022, 0.0005, 0.0081, respectively), and decreased levels of IL-10 in the supernatant of PBMCs of PE patients compared with control group ( p = 0.0011). There was significant upregulation of miR-106b and miR-326 ( p = 0.0048 and 0.028, respectively) in PE patients in comparison with the control group. CONCLUSIONS: These findings suggest that imbalance of Th17/Treg cells, regulated possibly via microRNAs, may be involved in the pathogenesis of PE, emphasizing on the importance of these cells in feto-maternal immune cross-talk. PMID- 30277562 TI - The role of the dorsal striatum in choice impulsivity. AB - It has long been recognized that the dorsal striatum is an essential brain region for control of action selection based on action-outcome contingency learning, particularly when the available actions are bound to rewarding outcomes. In principle, intertemporal choice in the delay-discounting task-a validated measure of choice impulsivity-involves reward-associated actions that require the recruitment of the dorsal striatum. Here, we conjecture about ways the dorsal striatum is involved in choice impulsivity. Based on a selective body of studies, we begin with a brief history of research on choice impulsivity and the dorsal striatum, and then provide a comprehensive summary of contemporary studies utilizing human neuroimaging and animal models to search for links between choice impulsivity and the dorsal striatum. In particular, we discuss in-depth the converging evidence for the associations of choice impulsivity with the reward valuation coded by the caudate, a ventral-to-dorsal gradient in the dorsal striatum, the origins of striatal afferents, and developmental maturation of frontostriatal connectivity during adolescence. PMID- 30277563 TI - The impact of Cymbopogon martinii essential oil on Cutibacterium (formerly Propionibacterium) acnes strains and its interaction with keratinocytes. AB - OBJECTIVES: The human skin microbiota is mainly composed of bacteria belonging to the genera Staphylococcus, Cutibacterium, Micrococcus and Corynebacterium, but on the skin of the face and back, ca. 50% of the total microbiota is represented by the bacterium Cutibacterium acnes. The aim of this research was to evaluate the impact of C. martini EO and its major compound, geraniol, on C. acnes. METHODS: The minimum inhibitory concentration against C. acnes strains, phenotypic changes and responses of the proteome was determined. In addition, was assessed the effect of compounds in RNA-binding assay, on C. acnes-exposed keratinocytes and on the C. acnes type distribution on shoulder skin. KEY FINDINGS: The range of the MIC was 0.7 to 1.6 mg/ml for the three main C. acnes types. There were no cytotoxic effects of compounds in the absence or presence of C. acnes; after 7 days of exposure to C. martini EO, we could not detect a major shift of the C. acnes types on shoulder skin that was found to be dominated by C. acnes strains of types II and IA2. CONCLUSIONS: Our work gives novel insight into the skin microbiota-interacting properties of C. martini EO. PMID- 30277564 TI - Paeonia lactiflora Pall. regulates the NF-kappaB-NLRP3 inflammasome pathway to alleviate cholestasis in rats. AB - OBJECTIVES: Cholestasis is a critical risk factor for severe hepatic disease or cirrhosis. The anti-inflammatory effect of Paeonia lactiflora Pall. (PLP), named Chishao in traditional Chinese medicine (TCM), on alpha-naphthylisothiocyanate (ANIT)-induced cholestasis model was tried to be elucidated in this research. METHODS: Therapeutic effect indices on hepatic function, including ALT, AST, TBIL, DBIL, ALP, TBA and gamma-GT, were measured. To further investigate the protective mechanism of PLP, the mRNA and protein expression levels of NF-kappaB NLRP3 inflammasome pathway were detected. RESULTS: Our results showed that compared with the model group, PLP could significantly reduce the increased serum indices such as ALT, AST, TBIL, DBIL, ALP, TBA and gamma-GT induced by ANIT in a dose-dependent way. Moreover, we found that PLP downregulated the mRNA expression levels including IKK, p65, NLRP3, caspase-1 and IL-1beta, especially at the large dose. Furthermore, PLP also significantly inhibited NF-kappaB-NLRP3 inflammasome pathway by decreasing the protein levels of p65, p-p65, p-IKK, NLRP3, caspase-1 and IL-1beta. CONCLUSIONS: The results indicated that PLP could ameliorate ANIT induced cholestasis in rats and the anti-inflammatory effect of PLP might be related to regulating NF-kappaB-NLRP3 inflammasome pathway. This study will provide scientific evidence for PLP as a potential drug candidate for cholestasis. PMID- 30277565 TI - Sexual orientation-related oral health disparities in the United States. AB - OBJECTIVE: Recent reports have documented health disparities according to sexual orientation and used the minority stress model as a framework for understanding their origins. To date, however, sexual orientation-related disparities in the oral health domain have not been evaluated. Accordingly, this study sought to investigate potential health disparities in objectively-assessed and subjective reports of oral heath among lesbian, gay, and bisexual adults relative to the heterosexual community-dwelling US population. METHODS: We used three consecutive cycles (2009-2014) of National Health and Nutrition Examination Survey (NHANES) data for men and women aged 18-59 years. We examined clinical measures of dental caries, tooth loss, chronic periodontitis, and oral human papillomavirus (HPV) as well as subjective reports of oral health status and use of dental services. RESULTS: Clinical measures of oral disease did not differ according to sexual orientation; however, bisexual adults were more likely to rate their oral health unfavorably (41%) than heterosexual adults (27%). Gay men reported "bone loss around teeth" more frequently (35%) than heterosexual (11%) and bisexual (10%) men. Bisexual individuals were more likely to confront barriers to accessing dental care (30%) versus heterosexual adults (19%). CONCLUSIONS: While clinical measures of oral health did not substantially differ between sexual orientation strata, subjective measures of oral health were worse among gay, lesbian, and bisexual adults versus heterosexual adults. Further study of the psychosocial construction of oral health among sexual minorities is warranted. PMID- 30277566 TI - Advance Care Planning in Cognitively Impaired Older Adults. AB - Older adults with cognitive impairment face many healthcare challenges, chief among them participating in medical decision-making about their own health care. Advance care planning (ACP) is the process whereby individuals communicate their wishes for future care with their clinicians and surrogate decision-makers while they are still able to do so. ACP has been shown to improve important outcomes for individuals with cognitive impairment, but rates of ACP for these individuals are low because of individual-, clinician-, and system-related factors. Addressing ACP early in the illness trajectory can maximize the chances that people can participate meaningfully. This article recommends best practices for approaching ACP for older adults with cognitive impairment. The importance of providing anticipatory guidance and eliciting values to guide future care to create a shared framework between clinicians, individuals, and surrogate decision makers is emphasized. It is recommended that ACP be approached as an iterative process to continue to honor and support people's wishes as cognitive impairment progresses and increasingly threatens independence and function. The article describes effective strategies for assessing decision-making capacity, identifying surrogate decision-makers, and using structured communication tools for ACP. It also provides guidelines for documentation and billing. Finally, special considerations for individuals with advanced dementia are described, including the use of artificial hydration and nutrition, decisions about site of care, and the role of hospice care. PMID- 30277567 TI - Statins for Primary Prevention in Older Adults-Moving Toward Evidence-Based Decision-Making. AB - OBJECTIVES: To determine the efficacy and safety of statins for primary prevention of atherosclerotic cardiovascular disease (ASCVD) events in older adults, especially those aged 80 and older and with multimorbidity. METHODS: The National Institute on Aging and the National Heart, Lung and Blood Institute convened A multidisciplinary expert panel from July 31 to August 1, 2017, to review existing evidence, identify knowledge gaps, and consider whether statin safety and efficacy data in persons aged 75 and older without ASCVD are sufficient; whether existing data can inform the feasibility, design, and implementation of future statin trials in older adults; and clinical trial options and designs to address knowledge gaps. This article summarizes the presentations and discussions at that workshop. RESULTS: There is insufficient evidence regarding the benefits and harms of statins in older adults, especially those with concomitant frailty, polypharmacy, comorbidities, and cognitive impairment; a lack of tools to assess ASCVD risk in those aged 80 and older; and a paucity of evidence of the effect of statins on outcomes of importance to older adults, such as statin-associated muscle symptoms, cognitive function, and incident diabetes mellitus. Prospective, traditional, placebo-controlled, randomized clinical trials (RCTs) and pragmatic RCTs seem to be suitable options to address these critical knowledge gaps. Future trials have to consider greater representation of very old adults, women, underrepresented minorities, and individuals of differing health, cognitive, socioeconomic, and educational backgrounds. Feasibility analyses from existing large healthcare networks confirm appropriate power for death and cardiovascular outcomes for future RCTs in this area. CONCLUSION: Existing data cannot address uncertainties about the benefits and harms of statins for primary ASCVD prevention in adults aged 75 and older, especially those with comorbidities, frailty, and cognitive impairment. Evidence from 1 or more RCTs could address these important knowledge gaps to inform person centered decision-making. J Am Geriatr Soc 66:2188-2196, 2018. PMID- 30277568 TI - Root coverage procedures for treating localised and multiple recession-type defects. AB - BACKGROUND: Gingival recession is defined as the oral exposure of the root surface due to a displacement of the gingival margin apical to the cemento-enamel junction and it is regularly linked to the deterioration of dental aesthetics. Successful treatment of recession-type defects is based on the use of predictable root coverage periodontal plastic surgery (RCPPS) procedures. This review is an update of the original version that was published in 2009. OBJECTIVES: To evaluate the efficacy of different root coverage procedures in the treatment of single and multiple recession-type defects. SEARCH METHODS: Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 15 January 2018), the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 12) in the Cochrane Library (searched 15 January 2018), MEDLINE Ovid (1946 to 15 January 2018), and Embase Ovid (1980 to 15 January 2018). The US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials (15 January 2018). No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA: We included randomised controlled trials (RCTs) only of at least 6 months' duration evaluating recession areas (Miller's Class I or II >= 3 mm) and treated by means of RCPPS procedures. DATA COLLECTION AND ANALYSIS: Screening of eligible studies, data extraction and risk of bias assessment were conducted independently and in duplicate. Authors were contacted for any missing information. We expressed results as random-effects models using mean differences (MD) for continuous outcomes and odds ratios (OR) for dichotomous outcomes with 95% confidence intervals (CI). We used GRADE methods to assess the quality of the body of evidence of our main comparisons. MAIN RESULTS: We included 48 RCTs in the review. Of these, we assessed one as at low risk of bias, 12 as at high risk of bias and 35 as at unclear risk of bias. The results indicated a greater reduction in gingival recession for subepithelial connective tissue grafts (SCTG) + coronally advanced flap (CAF) compared to guided tissue regeneration with resorbable membranes (GTR rm) + CAF (MD -0.37 mm; 95% CI -0.60 to -0.13, P = 0.002; 3 studies; 98 participants; low-quality evidence). There was insufficient evidence of a difference in gingival recession reduction between acellular dermal matrix grafts (ADMG) + CAF and SCTG + CAF or between enamel matrix protein (EMP) + CAF and SCTG + CAF. Regarding clinical attachment level changes, GTR rm + CAF promoted additional gains compared to SCTG + CAF (MD 0.35; 95% CI 0.06 to 0.63, P = 0.02; 3 studies; 98 participants; low quality evidence) but there was insufficient evidence of a difference between ADMG + CAF and SCTG + CAF or between EMP + CAF and SCTG + CAF. Greater gains in the keratinized tissue were found for SCTG + CAF when compared to EMP + CAF (MD 1.06 mm; 95% CI -1.36 to -0.76, P < 0.00001; 2 studies; 62 participants; low quality evidence), and SCTG + CAF when compared to GTR rm + CAF (MD -1.77 mm; 95% CI -2.66 to -0.89, P < 0.0001; 3 studies; 98 participants; very low-quality evidence). There was insufficient evidence of a difference in keratinized tissue gain between ADMG + CAF and SCTG + CAF. Few data exist on aesthetic condition change related to patients' opinion and patients' preference for a specific procedure. AUTHORS' CONCLUSIONS: Subepithelial connective tissue grafts, coronally advanced flap alone or associated with other biomaterial and guided tissue regeneration may be used as root coverage procedures for treating localised or multiple recession-type defects. The available evidence base indicates that in cases where both root coverage and gain in the width of keratinized tissue are expected, the use of subepithelial connective tissue grafts shows a slight improvement in outcome. There is also some weak evidence suggesting that acellular dermal matrix grafts appear as the soft tissue substitute that may provide the most similar outcomes to those achieved by subepithelial connective tissue grafts. RCTs are necessary to identify possible factors associated with the prognosis of each RCPPS procedure. The potential impact of bias on these outcomes is unclear.

AB - Nucleotide-binding, oligomerization domain (NOD)-like receptor family, pyrin domain containing 3 (NLRP3) gene polymorphism was reported to be associated with susceptibility, disease activity or anti-tumour necrosis factor (TNF) treatment response in rheumatoid arthritis (RA). However, the roles of NLRP3 inflammasome in the development of RA have not yet been elucidated fully. The present study aimed to study the role of NLRP3 inflammasome in RA. NLRP3 inflammasome activation in synovial tissues from RA and osteoarthritis (OA) patients were assessed by Western blot. Active caspase-1 in synovia was stained by a FAM-FLICA caspase-1 probe. Mice with collagen-induced arthritis (CIA) were treated with MCC950, a selective NLRP3 inhibitor, or vehicle for 2 weeks. The clinical score of arthritis, synovial inflammation and cartilage erosion were assessed. Proinflammatory cytokines were measured by enzyme-linked immunosorbent assay (ELISA). The results showed that NLRP3 inflammasome was highly activated in both synovia from RA patients and CIA mice. Activation of NLRP3 inflammasome occurred mainly in the infiltrating monocyte/macrophages in synovia, but not in fibroblast like synoviocytes. Treatment with MCC950 resulted in significantly less severe joints inflammation and bone destruction. NLRP3 inflammasome activation in the synovia was inhibited significantly by MCC950 with reduced production of interleukin (IL)-1beta. The inhibition of NLRP3 inflammasome activation by MCC950 was confirmed further in a human monocytic cell line, THP-1. In conclusion, NLRP3 inflammasome is involved in the pathogenesis of RA. Targeting NLRP3 inflammasome with a small molecule inhibitor might be a novel therapeutic strategy for RA. PMID- 30277571 TI - Burden of Restricted Activity and Associated Symptoms and Problems in Late Life and at the End of Life. AB - OBJECTIVES: To compare rates of restricted activity and associated symptoms and problems in the last 6 months of life with those in the period before the last 6 months of life. DESIGN: Prospective cohort study. SETTING: Greater New Haven, Connecticut. PARTICIPANTS: Community-living persons aged 70 and older (N=754). MEASUREMENTS: The occurrence of restricted activity (staying in bed for at least half the day or cutting down on usual activities) and 24 prespecified symptoms and problems leading to restricted activity was ascertained monthly for nearly 19 years. RESULTS: Rates of restricted activity per 100 person-months were 36.5 in the last 6 months of life versus 16.1 in the period before the last 6 months of life (P<.001). Of 737 participants with 1 month or more of restricted activity, rates of restricting symptoms per 100 person-months of restricted activity ranged from 8.0 for frequent or painful urination to 65.6 for been fatigued, and rates of restricting problems ranged from 0.1 for problem with alcohol to 23.4 for been afraid of falling. Rates were significantly higher in the last 6 months of life than in the prior period for 13 of the 24 restricting symptoms and problems (P<.05), most notably for shortness of breath (38.6 vs 21.8), weakness (37.3 vs 18.9), and confusion (31.2 vs 9.8). Mean (standard error) number of restricting symptoms and problems was significantly higher in the last 6 months of life (6.1 (0.1)) than in the prior period (4.7 (0.03)) (P<.001). CONCLUSION: Rates of restricted activity and associated symptoms and problems are substantially greater in the last 6 months of life than in the period before the last 6 months of life. Enhanced palliative care strategies may be needed to diminish the burden of distressing symptoms and problems at the end of life. PMID- 30277573 TI - "Killin' Ain't a Forgivin' Sin". PMID- 30277574 TI - A reinforcement learning approach to personalized learning recommendation systems. AB - Personalized learning refers to instruction in which the pace of learning and the instructional approach are optimized for the needs of each learner. With the latest advances in information technology and data science, personalized learning is becoming possible for anyone with a personal computer, supported by a data driven recommendation system that automatically schedules the learning sequence. The engine of such a recommendation system is a recommendation strategy that, based on data from other learners and the performance of the current learner, recommends suitable learning materials to optimize certain learning outcomes. A powerful engine achieves a balance between making the best possible recommendations based on the current knowledge and exploring new learning trajectories that may potentially pay off. Building such an engine is a challenging task. We formulate this problem within the Markov decision framework and propose a reinforcement learning approach to solving the problem. PMID- 30277575 TI - Moving beyond static survivorship care plans: A systems engineering approach to population health management for cancer survivors. AB - The American cancer survivor population is ever-growing, with necessary follow-up primarily accomplished in a high-touch fashion-adding to unsustainability and fragmentation of care. Given the complexities of the health care system processes needed to support survivorship, engineering approaches may best address performance deficits and facilitate the provision of patient-centered care. Such collaboration between health care and engineering is recommended for redesigning health care delivery systems. By using Systems Engineering Initiative for Patient Safety (SEIPS), a systems engineering model widely used to improve health care quality and delivery, the authors examine the work system to identify the barriers and facilitators to necessary care in the presence of a survivorship care plan and visit. Recommendations for future improvement include ensuring that care-planning processes are dynamic, clearly assigned, resilient, and integrated with electronic health record systems. PMID- 30277576 TI - GBGT1 is allelically diverse but dispensable in humans and naturally occurring anti-FORS1 shows an ABO-restricted pattern. AB - BACKGROUND: The FORS histo-blood group system was described in 2013 and much remains to be investigated regarding its genetic and immunohematologic characteristics, as well as its clinical importance. While presence of the c.887G>A-mutated GBGT1 gene, which results in FORS1 glycosphingolipid expression on human red blood cells (RBCs), is rare in the populations tested so far, naturally occurring anti-FORS1 in plasma appears common. STUDY DESIGN AND METHODS: The Erythrogene database was utilized to probe genetic variation in GBGT1 among 2504 individuals in the 1000 Genomes Project. We screened 1108 Swedish blood donors for three principally important single-nucleotide polymorphisms (c.363C>A, c.886C>T, and c.887G>A) and selected samples were analyzed further. Screening for naturally occurring anti-FORS1 in plasma from 100 donors was performed using antigen-positive RBCs. RESULTS: We identified 68 GBGT1 alleles, of which three were previously listed blood group alleles. Eight potential null alleles were observed, based on three different nonsense mutations. Four healthy donors were found homozygous for c.363C>A, which truncates the GBGT1-encoded Fs synthase prematurely. This is the first description of human knock-outs for GBGT1. The c.886C>T mutation that alters the same codon (p.Arg296Trp) changed by c.887G>A (p.Arg296Gln) was overexpressed to investigate if it induces the FORS1+ phenotype. However, c.886C>T did not result in synthesis of FORS1. We detected anti-FORS1 in 10% of all donors tested but none in the A1 or A1B groups. CONCLUSION: We have extended the knowledge of GBGT1 variants, allele frequencies, and the characteristics of naturally occurring antibodies in our newest carbohydrate blood group system, FORS. The finding of c.363C>A-homozygous donors indicates that GBGT1 is dispensable. PMID- 30277572 TI - Improving patient and caregiver outcomes in oncology: Team-based, timely, and targeted palliative care. AB - Over the past decade, a large body of evidence has accumulated supporting the integration of palliative care into oncology practice for patients with advanced cancer. The question is no longer whether palliative care should be offered, but what is the optimal model of delivery, when is the ideal time to refer, who is in greatest need of a referral, and how much palliative care should oncologists themselves be providing. These questions are particularly relevant given the scarcity of palliative care resources internationally. In this state-of-the science review directed at the practicing cancer clinician, the authors first discuss the contemporary literature examining the impact of specialist palliative care on various health outcomes. Then, conceptual models are provided to support team-based, timely, and targeted palliative care. Team-based palliative care allows the interdisciplinary members to address comprehensively the multidimensional care needs of patients and their caregivers. Timely palliative care, at its best, is preventive care to minimize crises at the end of life. Targeted palliative care involves identifying the patients most likely to benefit from specialist palliative care interventions, akin to the concept of targeted cancer therapies. Finally, the strengths and weaknesses of innovative care models, such as outpatient clinics, embedded clinics, nurse-led palliative care, primary palliative care provided by oncology teams, and automatic referral, are summarized. Moving forward, more research is needed to determine how different health systems can best personalize palliative care to provide the right level of intervention, for the right patient, in the right setting, at the right time.

AB - OBJECTIVE AND BACKGROUND: The expression of periodontitis, including age of onset, extent, and severity is considered to represent an interaction of the individual's oral microbiome and host response to the microbial challenge that is modified by both genetics and environmental factors. The aim of this study was to determine the distribution of periodontitis in a population of nonhuman primates, to document features of familial distribution that could reflect heritability and transmission of microbes with enhanced virulence. MATERIAL AND METHODS: This report presents our findings from evaluation of periodontal disease bone defects in skulls from 569 animals (5-31 years of age) derived from the skeletons of the rhesus monkeys (Macaca mulatta) of Cayo Santiago derived from eight matrilines over 6-9 generations. The distance from the base of alveolar bone to the cemento enamel junction on 1st/2nd premolars and 1st/2nd molars from all four quadrants was evaluated as a measure of periodontal disease. Additionally, we documented the presence of periodontitis in 79 living descendants within these matrilines. RESULTS: The results demonstrated an increased extent and severity of periodontitis with aging across all matrilines. Extensive heterogeneity in disease expression was observed among the animals and this was linked to specific periodontitis susceptible matrilines. Moreover, we identified some matrilines in which the members appeared to show some resistance to more severe disease, even with aging. CONCLUSION: Linking these disease variations to multigenerational matriarchal family units supported familial susceptibility of periodontitis. This familial disease relationship was reinforced by the distribution of naturally occurring periodontitis in the living descendants.

AB - The differentiation of the seed coat epidermal (SCE) cells in Arabidopsis thaliana leads to the production of a large amount of pectin-rich mucilage and a thick cellulosic secondary cell wall. The mechanisms by which cortical microtubules are involved in the formation of these pectinaceous and cellulosic cell walls are still largely unknown. Using a reverse genetic approach, we found that TONNEAU1 (TON1) recruiting motif 4 (TRM4) is implicated in cortical microtubule organization in SCE cells, and functions as a novel player in the establishment of mucilage structure. TRM4 is preferentially accumulated in the SCE cells at the stage of mucilage biosynthesis. The loss of TRM4 results in compact seed mucilage capsules, aberrant mucilage cellulosic structure, short cellulosic rays and disorganized cellulose microfibrils in mucilage. The defects could be rescued by transgene complementation of trm4 alleles. Probably, this is a consequence of a disrupted organization of cortical microtubules, observed using fluorescently tagged tubulin proteins in trm4 SCE cells. Furthermore, TRM4 proteins co-aligned with microtubules and interacted directly with CELLULOSE SYNTHASE 3 in two independent assays. Together, the results indicate that TRM4 is essential for microtubule array organization and therefore correct cellulose orientation in the SCE cells, as well as the establishment of the subsequent mucilage architecture. PMID- 30277579 TI - Calcium supplementation during pregnancy for preventing hypertensive disorders and related problems. AB - BACKGROUND: Pre-eclampsia and eclampsia are common causes of serious morbidity and death. Calcium supplementation may reduce the risk of pre-eclampsia, and may help to prevent preterm birth. This is an update of a review last published in 2014. OBJECTIVES: To assess the effects of calcium supplementation during pregnancy on hypertensive disorders of pregnancy and related maternal and child outcomes. SEARCH METHODS: We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (18 September 2017), and reference lists of retrieved studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs), including cluster-randomised trials, comparing high-dose calcium supplementation (at least 1 g daily of calcium) during pregnancy with placebo. For low-dose calcium we included quasi-randomised trials, trials without placebo, trials with cointerventions and dose comparison trials. DATA COLLECTION AND ANALYSIS: Two researchers independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Two researchers assessed the evidence using the GRADE approach. MAIN RESULTS: We included 27 studies (18,064 women). We assessed the included studies as being at low risk of bias, although bias was frequently difficult to assess due to poor reporting and inadequate information on methods.High-dose calcium supplementation (>= 1 g/day) versus placeboFourteen studies examined this comparison, however one study contributed no data. The 13 studies contributed data from 15,730 women to our meta-analyses. The average risk of high blood pressure (BP) was reduced with calcium supplementation compared with placebo (12 trials, 15,470 women: risk ratio (RR) 0.65, 95% confidence interval (CI) 0.53 to 0.81; I2 = 74%). There was also a reduction in the risk of pre-eclampsia associated with calcium supplementation (13 trials, 15,730 women: average RR 0.45, 95% CI 0.31 to 0.65; I2 = 70%; low quality evidence). This effect was clear for women with low calcium diets (eight trials, 10,678 women: average RR 0.36, 95% CI 0.20 to 0.65; I2 = 76%) but not those with adequate calcium diets. The effect appeared to be greater for women at higher risk of pre-eclampsia, though this may be due to small-study effects (five trials, 587 women: average RR 0.22, 95% CI 0.12 to 0.42). These data should be interpreted with caution because of the possibility of small-study effects or publication bias. In the largest trial, the reduction in pre-eclampsia was modest (8%) and the CI included the possibility of no effect.The composite outcome maternal death or serious morbidity was reduced with calcium supplementation (four trials, 9732 women; RR 0.80, 95% CI 0.66 to 0.98). Maternal deaths were no different (one trial of 8312 women: one death in the calcium group versus six in the placebo group). There was an anomalous increase in the risk of HELLP syndrome in the calcium group (two trials, 12,901 women: RR 2.67, 95% CI 1.05 to 6.82, high-quality evidence), however, the absolute number of events was low (16 versus six).The average risk of preterm birth was reduced in the calcium supplementation group (11 trials, 15,275 women: RR 0.76, 95% CI 0.60 to 0.97; I2 = 60%; low quality evidence); this reduction was greatest amongst women at higher risk of developing pre-eclampsia (four trials, 568 women: average RR 0.45, 95% CI 0.24 to 0.83; I2 = 60%). Again, these data should be interpreted with caution because of the possibility of small-study effects or publication bias. There was no clear effect on admission to neonatal intensive care. There was also no clear effect on the risk of stillbirth or infant death before discharge from hospital (11 trials, 15,665 babies: RR 0.90, 95% CI 0.74 to 1.09).One study showed a reduction in childhood systolic BP greater than 95th percentile among children exposed to calcium supplementation in utero (514 children: RR 0.59, 95% CI 0.39 to 0.91). In a subset of these children, dental caries at 12 years old was also reduced (195 children, RR 0.73, 95% CI 0.62 to 0.87).Low-dose calcium supplementation (< 1 g/day) versus placebo or no treatmentTwelve trials (2334 women) evaluated low dose (usually 500 mg daily) supplementation with calcium alone (four trials) or in association with vitamin D (five trials), linoleic acid (two trials), or antioxidants (one trial). Most studies recruited women at high risk for pre eclampsia, and were at high risk of bias, thus the results should be interpreted with caution. Supplementation with low doses of calcium reduced the risk of pre eclampsia (nine trials, 2234 women: RR 0.38, 95% CI 0.28 to 0.52). There was also a reduction in high BP (five trials, 665 women: RR 0.53, 95% CI 0.38 to 0.74), admission to neonatal intensive care unit (one trial, 422 women, RR 0.44, 95% CI 0.20 to 0.99), but not preterm birth (six trials, 1290 women, average RR 0.83, 95% CI 0.34 to 2.03), or stillbirth or death before discharge (five trials, 1025 babies, RR 0.48, 95% CI 0.14 to 1.67).High-dose (=/> 1 g) versus low-dose (< 1 g) calcium supplementationWe included one trial with 262 women, the results of which should be interpreted with caution due to unclear risk of bias. Risk of pre eclampsia appeared to be reduced in the high-dose group (RR 0.42, 95% CI 0.18 to 0.96). No other differences were found (preterm birth: RR 0.31, 95% CI 0.09 to 1.08; eclampsia: RR 0.32, 95% CI 0.07 to 1.53; stillbirth: RR 0.48, 95% CI 0.13 to 1.83). AUTHORS' CONCLUSIONS: High-dose calcium supplementation (>= 1 g/day) may reduce the risk of pre-eclampsia and preterm birth, particularly for women with low calcium diets (low-quality evidence). The treatment effect may be overestimated due to small-study effects or publication bias. It reduces the occurrence of the composite outcome 'maternal death or serious morbidity', but not stillbirth or neonatal high care admission. There was an increased risk of HELLP syndrome with calcium supplementation, which was small in absolute numbers.The limited evidence on low-dose calcium supplementation suggests a reduction in pre-eclampsia, hypertension and admission to neonatal high care, but needs to be confirmed by larger, high-quality trials. PMID- 30277580 TI - Responses of MAC-T Cells to Inhibited Stearoyl-CoA Desaturase 1 during cis-9, trans-11 Conjugated Linoleic Acid Synthesis. AB - Cis-9-conjugated, trans-11-conjugated linoleic acid (CLA) is known for its positive activities on human health. The synthesis of cis-9, trans-11 CLA in mammary glands is generally thought to be catalyzed by stearoyl-CoA desaturase 1 (SCD1), but this has not been rigorously established. In this study, we hypothesized that the inhibition of SCD1 (by CAY10566) would block the synthesis of cis-9, trans-11 CLA in bovine mammary alveolar cells (MAC-T) cells. Results showed that MAC-T cells incubated with 10 nM CAY10566 for 12 h (CAY) produced less cis-9, trans-11 CLA (p < 0.01), lower 14:1/(14:1 + 14:0)% (p < 0.01), more trans-11 18:1 (TVA) accumulation (p < 0.01), and reduced SCD1 mRNA levels (p < 0.01) compared with the control group (CON). Moreover, the mRNA abundances of sterol regulatory element-binding protein 1 [SREBPF1], acyl-CoA synthetase short chain family member 2 [ACSS2], and lipin 1 [LPIN1] were significantly elevated when SCD1 was inhibited in the CAY group (p < 0.05). Taken together, CAY10566 inhibition of SCD1 resulted in lower cis-9, trans-11 CLA synthesis ability, and SREBF1, ACSSS2, and LPIN1 were negatively associated with SCD1. These findings not only provide the direct evidence that cis-9, trans-11 CLA synthesis is catalyzed by SCD1, but also help us understand the responses of MAC-T cells to SCD1 inhibition. PMID- 30277581 TI - Racial Differences in Cause-Specific Mortality Between Community-Dwelling Older Black and White Adults. AB - OBJECTIVES: To understand which causes of death are higher in black than white community-dwelling older adults and determine whether differences in baseline risk factors explain racial differences in mortality. DESIGN: Longitudinal cohort study (Health, Aging, and Body Composition Study). SETTING: Pittsburgh, Pennsylvania; and Memphis, Tennessee. PARTICIPANTS: Black and white men and women aged 70 to 79 during recruitment (N=3,075; 48% men, 42% black) followed for a median of 13 years. MEASUREMENTS: A committee of physicians adjudicated cause of death, which was categorized as cardiovascular disease (CVD), stroke, cancer, dementia, pulmonary, infection, kidney, or other causes. Using competing risks regression, we examined whether known risk factors at baseline (demographic characteristics, smoking, body mass index, chronic diseases, physical function, cognition) could explain racial differences in cause-specific mortality risk. RESULTS: During follow-up, 1,991 (65%) participants died. Black participants died at higher rates from cancer (hazard ratio (HR)=1.36, 95% confidence interval (CI)=1.14-1.63), kidney disease (HR=2.09, 95% CI=1.16-3.74), stroke (HR=1.31, 95% CI=0.98-1.76); and CVD (HR=1.16, 95% CI=0.98-1.37). Poorer physical and cognitive performance at baseline among black participants explained most of the racial difference in risks of dying from kidney disease, stroke, and CVD but not cancer. When examining types of cancer deaths, black participants died at higher rates from multiple myeloma, pancreatic cancer, and prostate cancer, which baseline risk factors did not explain either. CONCLUSION: Factors contributing to poorer physical and cognitive performance in similarly aged black men and women could be targets to reduce excess mortality from CVD, stroke, and kidney disease. More work is needed to identify factors contributing to cancer mortality disparities. PMID- 30277582 TI - Long-term school-level effects of the Olweus Bullying Prevention Program (OBPP). AB - In agreement with two predictions, this somewhat unusual study documented that 70 elementary schools (A-schools) with continued and repeated use of the Olweus Bullying Questionnaire (OBQ) in a four-year follow-up period of 2007-2010, two to eight years after original implementation of the Olweus Bullying Prevention Program (OBPP), had a clearly more favorable long-term development in terms of being-bullied problems, as measured with a completely independent data source, the National Pupil Survey than 102 comparable schools (B-schools) that had not conducted any OBQ-surveys in the same period. The odds of being bullied for students in a Norwegian average elementary school were also almost 40% higher than for students who attended a school with continued use of the OBQ, and very likely, other components of the program. Several alternative explanations of the findings were explored and found wanting. Results suggested that A-schools with continued use had changed their "school culture" for the better with regard to awareness, preparedness and competence in handling and preventing bullying. This form of 'organizational learning' has major consequences in that new groups of students will benefit from such a school environment. It was generally concluded in spite of a highly stable average of the level of bullying problems in Norway that it is fully possible to substantially reduce such problems not only in one year evaluations, as has been amply documented before, but also in the long term, up to eight years after original implementation, with a program such as the Olweus Bullying Prevention Program. PMID- 30277583 TI - Wnt/beta-catenin signaling cascade: A promising target for glioma therapy. AB - Glioma is one of the most treatment-refractory intracranial tumors, and the aberrant expressed Wnt/beta-catenin pathway is closely associated with glioma malignancy. In this regard, Wnt/beta-catenin signaling has been reported to play an essential role in cellular proliferation, migration, invasion, and angiogenesis, therefore contributing to glioma progression. However, the underlying mechanisms of Wnt/beta-catenin signaling involvement in gliomagenesis remain unknown. Here, we present an overview of the Wnt components and then go on to summarize the current knowledge describing the multitude of roles of Wnt/beta catenin in glioma, which are mediated by transcription factors, microRNAs, long noncoding RNAs, and so on. In the latter portion of the review, we elaborate the increasing apparent crosstalk of Wnt/beta-catenin pathway with PI3K/AKT signaling involved in these processes. Ultimately, compounds targeting the Wnt/beta-catenin are described in glioma. As better understanding of the regulatory mechanisms to glioma malignancies increases, Wnt/beta-catenin cascade may represent an area of developmental glioma therapeutics focus. PMID- 30277584 TI - Bayesian varying coefficient kernel machine regression to assess neurodevelopmental trajectories associated with exposure to complex mixtures. AB - Exposure to environmental mixtures can exert wide-ranging effects on child neurodevelopment. However, there is a lack of statistical methods that can accommodate the complex exposure-response relationship between mixtures and neurodevelopment while simultaneously estimating neurodevelopmental trajectories. We introduce Bayesian varying coefficient kernel machine regression (BVCKMR), a hierarchical model that estimates how mixture exposures at a given time point are associated with health outcome trajectories. The BVCKMR flexibly captures the exposure-response relationship, incorporates prior knowledge, and accounts for potentially nonlinear and nonadditive effects of individual exposures. This model assesses the directionality and relative importance of a mixture component on health outcome trajectories and predicts health effects for unobserved exposure profiles. Using contour plots and cross-sectional plots, BVCKMR also provides information about interactions between complex mixture components. The BVCKMR is applied to a subset of data from PROGRESS, a prospective birth cohort study in Mexico city on exposure to metal mixtures and temporal changes in neurodevelopment. The mixture include metals such as manganese, arsenic, cobalt, chromium, cesium, copper, lead, cadmium, and antimony. Results from a subset of Programming Research in Obesity, Growth, Environment and Social Stressors data provide evidence of significant positive associations between second trimester exposure to copper and Bayley Scales of Infant and Toddler Development cognition score at 24 months, and cognitive trajectories across 6-24 months. We also detect an interaction effect between second trimester copper and lead exposures for cognition at 24 months. In summary, BVCKMR provides a framework for estimating neurodevelopmental trajectories associated with exposure to complex mixtures. PMID- 30277585 TI - Distal-less homeobox 3, a negative regulator of myogenesis, is downregulated by microRNA-133. AB - Distal-less homeobox 3 (Dlx3), a member of the Dlx family of homeobox proteins, is a transcriptional activator of runt-related transcription factor 2 (Runx2) during osteogenic differentiation. It has been demonstrated that forced expression of Runx2 induces an osteogenic program and ectopic calcification in muscles. Therefore, it would be reasonable to predict that Dlx3 also affects myogenic differentiation. The relationship between Dlx3 and myogenesis, however, remains poorly understood. Therefore, in this study, the role and regulation of Dlx3 during myogenic differentiation were investigated. Expression level of Dlx3 was downregulated in human mesenchymal stem cells (MSCs), mouse MSCs, and C2C12 cells cultured in myogenic medium. Dlx3 level was inversely correlated with myogenic differentiation 1 and the muscle-specific microRNA, microRNA-133 (miR 133). The expression level of Runx2 was closely regulated by Dlx3 even under myogenic conditions. Overexpression of Dlx3 markedly downregulated expression levels of myogenic transcription factors and myotube formation in C2C12 cells, whereas Dlx3 knockdown enhanced myogenic differentiation. The Dlx3 3' untranslated region (3'-UTR) has two potential binding sites for miR-133. Luciferase reporter assays demonstrated that Dlx3 is a direct target of miR-133a and miR-133b, and that the two target sites are redundantly active. Taken together, these results suggest that Dlx3 is a negative regulator of myogenic differentiation and that miR-133a and miR-133b enhance myogenic differentiation, partly through inhibition of Dlx3 expression via direct targeting of the Dlx3 3' UTR. PMID- 30277587 TI - Dietary Nondigestible Polysaccharides Ameliorate Colitis by Improving Gut Microbiota and CD4+ Differentiation, as Well as Facilitating M2 Macrophage Polarization. AB - BACKGROUND: The aim of this study was to investigate the therapeutic mechanism of a specific multifiber mix diet (MF) designed to match the fiber content of a healthy diet in interleukin-10 knockout (IL-10-/-) mice with spontaneous chronic colitis displaying similar characteristics to those of human Crohn's disease (CD). METHODS: Sixteen-week-old IL-10-/- mice were used for the experiments with MF diet for 4 weeks. Severity of colitis, the composition of the fecal microbiota, expression of Th1/Th17 cells, myeloperoxidase (MPO) concentrations, and inflammatory cytokines and chemokines (tumor necrosis factor-alpha [TNF alpha], IL-6, macrophage inflammatory protein [MIP]-2, monocyte chemoattractant protein-1 [MCP-1], and MIP-1alpha), as well as arginase 1 (Arg1) and signal transducers and activators of transcription 6 (STAT6) proteins, were measured at the end of the experiment. In addition, the corresponding metabolites (short chain fatty acids) of MF on CD4+CD25+Foxp3+ regulatory T cells (Tregs) were also detected in vivo and in vitro. RESULTS: MF treatment significantly ameliorated colitis associated with decreased lamina propria frequency of Th1/Th17 cells, MPO concentrations, and inflammatory cytokines and chemokines (TNF-alpha, IL-6, MIP 2, MCP-1, and MIP-1alpha). An increase in gut microbial diversity was observed after MF treatment compared with IL-10-/- mice, including a significant increase in bacteria belonging to the Firmicutes phylum and a significant decrease in bacteria belonging to the Proteobacteria phylum. Moreover, MF treatment increased the differentiation of CD4+CD25+Foxp3+ Tregs mainly by microbial metabolites butyrate. In addition, Arg1 and STAT6 proteins were also significantly increased after MF treatment. CONCLUSIONS: These results shed light on the contribution of MF treatment to the CD mouse model and suggest that MF has potential as a therapeutic strategy for enhancing efficacy in inducing remission in patients with active CD. PMID- 30277586 TI - Recovery from acute lung injury can be regulated via modulation of regulatory T cells and Th17 cells. AB - Acute lung injury (ALI) is a severe inflammatory disease, for which no specific treatment exists. The decreased ratio of regulatory T cells (CD4+ CD25+ FoxP3 Tregs) and Th17 cells is implicated in ALI and inflammation. We here investigated whether maintaining the balance of CD4+ CD25+ Foxp3+ Tregs and Th17 cells can alleviate lung injury. For CD4+ CD25+ FoxP3 Treg depletion, 200 MUg of an anti CD25 antibody was administered intraperitoneally per mouse on days -3 and -1 before lipopolysaccharide (LPS) instillation. And 150 MUg of TGF-beta was administered intraperitoneally per mouse on day 0 after LPS instillation. To down regulate of Th17 cells, 200 MUg per mouse of isotype, IL-17 or IL-22 antibodies were injected intraperitoneally into mice at days 0 after LPS instillation. We detected lung morphology; lung wet-to-dry weight ratio; protein concentration, the count of total cells, neutrophils and macrophages, and cytokines in bronchoalveolar lavage fluid (BALF). And we also evaluated the percentage of CD4+ CD25+ Foxp3+ Tregs in lung, and Th17 cells in lung. CD4+ CD25+ Foxp3+ Tregs depletion via anti-CD25 treatment or TGF-beta neutralization delayed recovery of ALI. The prolonged inflammation was mainly dominated by neutrophils, macrophages and Th17 cells. Furthermore, inhibition of Th17 cells via monoclonal antibodies against IL-17 and IL-22 alleviated ALI inflammation by inhibiting the recruitment of neutrophils and macrophages, increasing the number of CD4+ CD25+ Foxp3+ Tregs. Our findings support a critical role for CD4+ CD25+ Foxp3+ Tregs in regulating from ALI pathophysiology, and a potential therapeutic role for the inhibition of Th17 cells in ALI treatment. These findings provide a rationale for treating patients with ALI by modulating CD4+ CD25+ Foxp3+ Tregs and Th17 cells. PMID- 30277589 TI - 2-deoxy-D-glucose augments photodynamic therapy induced mitochondrial caspase independent apoptosis and energy-mediated autophagy. AB - OBJECTIVES: Compared to normal cells, malignant cells have a high degree of aerobic glycolysis, also known as the Warburg effect. Therefore, supplementing photodynamic therapy (PDT), an established cancer therapy, with metabolic inhibitors can augment the mitochondrial damage by depleting ATP. To assess the combined impact of the glycolysis inhibitor 2-deoxy-D-glucose (2-DG) and PDT on apoptosis and autophagy in human breast cancer cells, and examine the molecular basis. METHODS: Calcium-AM/PI double staining was used to evaluate cell viability. Reactive oxygen species (ROS), mitochondria membrane potential (MMP), nuclear morphology, and autophagosomes were measured using specific fluorescent markers. In addition, translocation of the apoptosis inducing factor (AIF) from the mitochondria to nucleus was imaged by confocal laser scanning microscopy, and DNA fragmentation was measured using PI staining and comet assay. PGC-1alpha expression, oxidative phosphorylation, ATP levels, and autophagy related proteins were detected by qRT-PCR, seahorse bioscience XFP extracellular flux analyzer, and Western blotting, respectively. RESULTS: Compared to with either monotherapy, 2-DG+PDT resulted in significantly higher cytotoxicity in the three breast cancer cell lines (MDA-MB-231, MCF-7, and 4T1), which was consistent with tumor growth regression trends seen in the 4T1 xenograft model. A synergistic augmentation of mitochondrial dysfunction (in terms of ROS generation, MMP loss, and PGC-1alpha down-regulation) and ATP depletion was seen in cells receiving 2-DG and PDT. In addition, nuclear translocation of AIF and the subsequent DNA damage indicated that the cytotoxic effects were mediated by a caspase-independent mechanism, which was relieved by the ROS scavenger N-acetylcysteine. Autophagy via the AMP activated protein kinase (AMPK) was also observed following 2-DG+PDT, and reversed upon pre-treatment with the autophagy inhibitor 3-methyladenine. CONCLUSIONS: The anti-cancer effects of 2-DG+PDT are mediated by both mitochondria triggered apoptosis and AMPK-mediated autophagy. Lasers Surg. Med. (c) 2018 Wiley Periodicals, Inc. PMID- 30277588 TI - Simultaneous Alcohol and Marijuana Use Among Young Adult Drinkers: Age-Specific Changes in Prevalence from 1977 to 2016. AB - BACKGROUND: The overall prevalence of U.S. young adult alcohol use has decreased, but little is known about historical change in related behaviors such as simultaneous alcohol and marijuana (SAM) use that may increase alcohol-related risks and societal costs. The purpose of this paper was to examine historical change in SAM use prevalence among U.S. young adult alcohol users from 1977 to 2016, and consider the extent to which observed historical change in SAM use among alcohol users reflects co-occurring change in marijuana use during these years. METHODS: Data on past 12-month alcohol, marijuana, and SAM use at up to 6 modal ages (19/20, 21/22, 23/24, 25/26, 27/28, and 29/30) were collected from 11,789 individuals (45.0% men) participating in the Monitoring the Future panel study. Annual prevalence estimates within modal age group were obtained; historical SAM use trends among alcohol and marijuana users were estimated. RESULTS: From 2014 to 2016, SAM use was reported by approximately 30% of alcohol users aged 19/20 and 21/22, and 20 to 25% of alcohol users aged 23/24 through 29/30. Since the mid-1990s, age-specific historical trends in SAM use prevalence among alcohol users followed 1 of 4 patterns: significant increase followed by oscillating increases/decreases (at modal age 19/20), consistent and significant increases (at modal ages 21/22, 23/24, and 25/26), stability followed by increase (at modal ages 27/28), or stability (at modal ages 29/30). In contrast, SAM use trends among marijuana users primarily reflected stability, with some evidence of a decrease across time at modal ages 19/20 and 23/24. Historical change in SAM prevalence among alcohol users was strongly and positively correlated with changes in overall marijuana use prevalence. CONCLUSIONS: A growing proportion of early and mid-young adult alcohol users reported SAM use, with the highest risk among those in the early years of young adulthood. Young adult SAM use may continue to increase in proportion to the degree that young adult marijuana use continues to increase. PMID- 30277590 TI - RI-MP3 calculations of biomolecules based on the fragment molecular orbital method. AB - In this study, the third-order Moller-Plesset perturbation (MP3) theory using the resolution of the identity (RI) approximation was combined with the fragment molecular orbital (FMO) method to efficiently calculate a high-order electron correlation energy of biomolecular systems. We developed a new algorithm for the RI-MP3 calculation, which can be used with the FMO scheme. After test calculations using a small molecule, the FMO-RI-MP3 calculations were performed for two biomolecular systems comprising a protein and a ligand. The computational cost of these calculations was only around 5 and 4 times higher than those of the FMO-RHF calculations. The error associated with the RI approximation was around 2.0% of the third-order correlation contribution to the total energy. However, the RI approximation error in the interaction energy between the protein and ligand molecule was insignificantly small, which reflected the negligible error in the inter fragment interaction energy.

AB - After an overview of the Food and Drugs Administration's 2012 draft guidance on enrichment strategies for clinical trials to support drug/biologic approval, we describe subsequent advances in adaptive enrichment designs in this direction.

PMID- 30277592 TI - Excited-State Reactivity of [Mn(im)(CO)3 (phen)]+ : A Structural Exploration. AB - The electronic excited state reactivity of [Mn(im)(CO)3 (phen)]+ (phen = 1,10 phenanthroline; im = imidazole) ranging between 420 and 330 nm have been analyzed by means of relativistic spin-orbit time-dependent density functional theory and wavefunction approaches (state-average-complete-active-space self-consistent field/multistate CAS second-order perturbation theory). Minimum energy conical intersection (MECI) structures and connecting pathways were explored using the artificial force induced reaction (AFIR) method. MECIs between the first and second singlet excited states (S1 /S2 -MECIs) were searched by the single component AFIR (SC-AFIR) algorithm combined with the gradient projection type optimizer. The structural, electronic, and excited states properties of [Mn(im)(CO)3 (phen)]+ are compared to those of the Re(I) analogue [Re(im)(CO)3 (phen)]+ . The high density of excited states and the presence of low-lying metal centered states that characterize the Mn complex add complexity to the photophysics and open various dissociative channels for both the CO and imidazole ligands.

AB - High-dose radiation-induced tissue damage is a major limiting factor in the medical application of nuclear technology. Herein, we tested 28-day repeated-dose toxicity of KMRC011, an agonist of toll-like receptor (TLR) 5, which is being developed as a medical countermeasure for radiation, using cynomolgus monkeys. KMRC011 (0.01, 0.02 or 0.04 mg/kg/day) was intramuscularly injected once daily for 4 weeks, and each two monkeys in both control and 0.04 mg/kg/day group were observed for an additional 2-week recovery period. There were no dose-related toxicological changes in mortality, clinical observations, body weight, food consumption, ophthalmological findings, electrocardiographs, coagulation, serum chemistry, organ weights, or urinalysis and urine chemistry. Although treatment related changes, such as increased white blood cells, increased absolute and relative neutrophils, decreased relative lymphocytes and inflammatory lesions, were noted in the maximum dose group, these findings were not observed after the 2-week recovery period. Further, we considered that the kidneys and heart may be target organs of TLR5 agonists, as well as the spleen, and that autophagic signals can be triggered in tissue damage and the repair process. Importantly, accumulation of p62 protein, an indicator of autophagy, and a decrease of caveolin-1 protein, a regulator of TLR5 protein half-life, were found in both tissues from the highest dose group. Therefore, we conclude that the no-observed adverse-effect level for KMRC011 may be greater than 0.04 mg/kg/day in male and female monkeys. Additionally, we propose that further studies are needed to identify the molecular signals, which are related to KMRC011-induced adverse effects.

AB - Doped clusters by Si16 cage encapsulating group-IV metal atoms (M@Si16 , M = Ti, Zr and Hf) are computationally investigated by both density functional theory (DFT) and high-level CCSD(T) method. Their low-energy structures are globally searched using a genetic algorithm based on DFT. The ground state structures of neutral and anionic M@Si16 are determined by calculating the vertical and adiabatic detachment energies and comparing them with the experimental data. For neutral Ti@Si16 , the Frank-Kasper (FK) deltahedron with T d symmetry and distorted FK isomer with C3v symmetry are nearly degenerate as the ground state and may coexist in laboratory, while the distorted FK isomer is the most probable structure for Ti@Si16 - anion. For neutral and anionic Zr@Si16 and Hf@Si16 clusters, the ground states at finite temperatures up to 300 K are the fullerene like D 4d bitruncated square trapezohedron. These theoretical results establish a more complete picture for the most stable structures of M@Si16 clusters, which possess large gaps and may serve as building blocks for electronic and optoelectronic applications. PMID- 30277595 TI - Association between chronic viral hepatitis and metabolic syndrome in southern Taiwan: a large population-based study. AB - BACKGROUND: The impact of metabolic syndrome (MetS) on hepatitis is an interesting issue. AIM: To evaluate the association of MetS and chronic viral hepatitis including hepatitis B virus (HBV) and hepatitis C virus (HCV) infection in southern Taiwan. METHODS: From 2004 to 2013, a series of community-based health screenings for residents aged 40 and older were held in Tainan city. MetS was defined according to the Joint Scientific Statement. Cut-offs of body-mass index measures of 24 kg/m2 and 27 kg/m2 were used to stratify lean, overweight and obese subjects. RESULTS: We enrolled 180 359 participants; the prevalence of MetS was 30.1%, which was significantly associated with advanced age and female sex. There were 18 726 (10.4%) HBV, 13 428 (7.4%) HCV, 1337 (0.7%) HBV plus HCV (B+C) and 146 868 (81.5%) non-HBV non-HCV participants (NBNC). Prevalence rates of MetS in subjects with HBV, HCV, B+C and NBNC were 25.2%, 31.5%, 28.9% and 30.7% respectively (P < 0.001). There were 18.8% lean body, 35.4% overweight and 45.8% obese participants among 54 361 MetS subjects. Lean MetS subjects were older, had more diabetes, and had higher metabolic component levels, but lower alanine transaminase and aspartate transaminase-platelet ratio index levels compared with obese MetS subjects. HCV infection was positively associated with MetS (P < 0.001). However, HBV infection was inversely associated with MetS only among lean subjects (P = 0.002), but not among the general population. CONCLUSIONS: This large population-based study indicated that HCV infection was positively associated with MetS. However, HBV infection was inversely associated with MetS only among lean subjects. PMID- 30277596 TI - KDM6B promotes ovarian cancer cell migration and invasion by induced transforming growth factor-beta1 expression. AB - KDM6B, also known as JMJD3, is a member of the family of histone lysine demethylase (KDMs), which is closely related to many types of cancers. However, its role and the underlying mechanisms in ovarian cancer remain unknown. Here we show that KDM6B is elevated in epithelial ovarian cancer and its expression level is closely related with metastasis and invasion. In addition, survival analysis showed that high expression of KDM6B was associated with low overall survival in ovarian cancer patients. Overexpression of KDM6B in epithelial ovarian cancer cells promoted proliferation, epithelial-mesenchymal transition (EMT), migration and invasion in vitro, and enhanced metastatic capacities in vivo. On the contrary, silencing KDM6B in invasive and metastatic ovarian cancer cells inhibited these processes. Mechanistically, we found that KDM6B exerts its function by modulating the transforming growth factor-beta1 (TGF-beta1) expression, and TGF-beta1 signal pathway inhibitor LY2157299 significantly inhibited KDM6B-induced proliferation, migration, metastasis, and EMT in ovarian cancer cells. Our findings, for the first time, reveal the pivotal role of KDM6B in the invasion and metastatic behavior of epithelial ovarian cancer. Thus, targeting KDM6B may be a useful strategy to interfere with these behaviors of epithelial ovarian cancer. PMID- 30277597 TI - Expression of exosomal microRNAs during chondrogenic differentiation of human bone mesenchymal stem cells. AB - The aim of the current study was to compare the expression of microRNAs (miRNAs) in exosomes derived from human bone mesenchymal stem cells (hBMSCs) with and without chondrogenic induction. Exosomes derived from hBMSCs were isolated and identified. Microarray analysis was performed to compare miRNA expression between exosomes derived from hBMSCs with and without chondrogenic induction, and quantitative real-time polymerase chain reaction (qRT-PCR) was used to verify the differentially expressed miRNAs. hBMSCs were transfected with miRNA mimic to extract miRNA-overexpressed exosomes. The results showed that most exosomes exhibited a cup-shaped or round-shaped morphology with a diameter of approximately 50-200 nm and expressed CD9 and CD63. We detected 141 miRNAs that were differentially expressed with and without chondrogenic induction by over a twofold change, including 35 upregulated miRNAs, such as miR-1246, miR-1290, miR 193a-5p, miR-320c, and miR-92a, and 106 downregulated miRNAs, such as miR-377-3p and miR-6891-5p. qRT-PCR analysis validated these results. Exosomes derived from hBMSCs overexpressing miR-320c were more efficient than normal exosomes derived from control hBMSCs at promoting osteoarthritis chondrocyte proliferation, down regulated matrix metallopeptidase 13 and up-regulated (sex determining region Y) box 9 expression during hBMSC chondrogenic differentiation. In conclusion, we identified a group of upregulated miRNAs in exosomes derived from hBMSCs with chondrogenic induction that may play an important role in mesenchymal stem cell derived exosomes in cartilage regeneration and, ultimately, the treatment of arthritis. We demonstrated the potential of these modified exosomes in the development of novel therapeutic strategies. PMID- 30277598 TI - Functional characterization of the Sox2, c-Myc, and Oct4 promoters. AB - To better understand the mechanisms in transcriptional regulation, we analyzed the promoters of the reprogramming key genes Sox2, c-Myc, and Oct4. Here, we cloned different 5' deletions of the goat Sox2, c-Myc, and Oct4 promoters, and evaluated their functions by green fluorescent protein reporter system and dual luciferase reporter system. Site-directed mugagenesis and epigenetic modifiers were used to explore the influence of transcription binding sites and epigenetic status on the promoters. The results suggested that the basal promoters were located in the - 109 to 49, - 147 to 1, and - 96 to 30 bp regions of the Sox2, c Myc, and Oct4 promoters. The transcription factors that identified to influence the Sox2, c-Myc, and Oct4 promoter activities were Elf-1 and activating protein 2 (AP-2), C/EBP and Sp1, and Mzf1 and Sp1, respectively. The epigenetic alternation of the Sox2, c-Myc, and Oct4 promoters by 5-aza-2'-deoxycytidine or/and trichostatin A significantly increased the promoter activities. In conclusion, the result determined the core promoter areas of the Sox2, c-Myc, and Oct4 genes, and identified the transcription factors that influence their promoter activities. We also verified that the Sox2, c-Myc, and Oct4 promoters were hypermethylated and hypoacetylated. PMID- 30277599 TI - CCL17 exerts a neuroimmune modulatory function and is expressed in hippocampal neurons. AB - Chemokines are important signaling molecules in the immune and nervous system. Using a fluorescence reporter mouse model, we demonstrate that the chemokine CCL17, a ligand of the chemokine receptor CCR4, is produced in the murine brain, particularly in a subset of hippocampal CA1 neurons. We found that basal expression of Ccl17 in hippocampal neurons was strongly enhanced by peripheral challenge with lipopolysaccharide (LPS). LPS-mediated induction of Ccl17 in the hippocampus was dependent on local tumor necrosis factor (TNF) signaling, whereas upregulation of Ccl22 required granulocyte-macrophage colony-stimulating factor (GM-CSF). CCL17 deficiency resulted in a diminished microglia density under homeostatic and inflammatory conditions. Further, microglia from naive Ccl17 deficient mice possessed a reduced cellular volume and a more polarized process tree as assessed by computer-assisted imaging analysis. Regarding the overall branching, cell surface area, and total tree length, the morphology of microglia from naive Ccl17-deficient mice resembled that of microglia from wild-type mice after LPS stimulation. In line, electrophysiological recordings indicated that CCL17 downmodulates basal synaptic transmission at CA3-CA1 Schaffer collaterals in acute slices from naive but not LPS-treated animals. Taken together, our data identify CCL17 as a homeostatic and inducible neuromodulatory chemokine affecting the presence and morphology of microglia and synaptic transmission in the hippocampus. PMID- 30277600 TI - Effect of simvastatin in different concentrations on free radicals in A-2058 human melanoma malignum cells-EPR studies. AB - The influence of concentration of simvastatin (SIM) on free radicals in A-2058 human melanoma malignum cells was studied. The proliferation assay for melanoma A 2058 cells with SIM in concentration range from 0.1 to 20 uM was performed. SIM in the concentrations of 0.1, 0.3, and 1 MUM only slightly changed the growth of A-2058 cells, but the growth of the cells considerably decreased for higher concentrations of SIM. Free radicals in the cells were examined by an X-band (9.3 GHz) electron paramagnetic resonance (EPR) spectroscopy. o-Semiquinone free radicals with g-factors in the range of 2.0060 to 2.0065 were found in A-2058 cells. The asymmetric broad EPR spectra with linewidths (DeltaBpp) from 0.87 to 1.25 mT were measured. The fast spin-lattice relaxation processes characterized all the tested cells. The free radical concentrations in the all A-2058 cells cultured with SIM were lower than in the control cells. The quenching of free radicals in A-2058 cells depended on concentration of SIM. This effect was the weakest for concentration of SIM of 3 MUM. The strongest decrease of free radical concentration caused SIM in concentration of 1 MUM. PMID- 30277601 TI - The Impact of Parental and Medical Leave Policies on Socioeconomic and Health Outcomes in OECD Countries: A Systematic Review of the Empirical Literature. AB - : Policy Points: Historically, reforms that have increased the duration of job protected paid parental leave have improved women's economic outcomes. By targeting the period around childbirth, access to paid parental leave also appears to reduce rates of infant mortality, with breastfeeding representing one potential mechanism. The provision of more generous paid leave entitlements in countries that offer unpaid or short durations of paid leave could help families strike a balance between the competing demands of earning income and attending to personal and family well-being. CONTEXT: Policies legislating paid leave from work for new parents, and to attend to individual and family illness, are common across Organisation for Economic Co-operation and Development (OECD) countries. However, there exists no comprehensive review of their potential impacts on economic, social, and health outcomes. METHODS: We conducted a systematic review of the peer-reviewed literature on paid leave and socioeconomic and health outcomes. We reviewed 5,538 abstracts and selected 85 published papers on the impact of parental leave policies, 22 papers on the impact of medical leave policies, and 2 papers that evaluated both types of policies. We synthesized the main findings through a narrative description; a meta-analysis was precluded by heterogeneity in policy attributes, policy changes, outcomes, and study designs. FINDINGS: We were able to draw several conclusions about the impact of parental leave policies. First, extensions in the duration of paid parental leave to between 6 and 12 months were accompanied by attendant increases in leave-taking and longer durations of leave. Second, there was little evidence that extending the duration of paid leave had negative employment or economic consequences. Third, unpaid leave does not appear to confer the same benefits as paid leave. Fourth, from a population health perspective, increases in paid parental leave were consistently associated with better infant and child health, particularly in terms of lower mortality rates. Fifth, paid paternal leave policies of adequate length and generosity have induced fathers to take additional time off from work following the birth of a child. How medical leave policies for personal or family illness influence health has not been widely studied. CONCLUSIONS: There is substantial quasi-experimental evidence to support expansions in the duration of job-protected paid parental leave as an instrument for supporting women's labor force participation, safeguarding women's incomes and earnings, and improving child survival. This has implications, in particular, for countries that offer shorter durations of job-protected paid leave or lack a national paid leave entitlement altogether. PMID- 30277604 TI - Toward Mass Production of CVD Graphene Films. AB - Chemical vapor deposition (CVD) is considered to be an efficient method for fabricating large-area and high-quality graphene films due to its excellent controllability and scalability. Great efforts have been made to control the growth of graphene to achieve large domain sizes, uniform layers, fast growth, and low synthesis temperatures. Some attempts have been made by both the scientific community and startup companies to mass produce graphene films; however, there is a large difference in the quality of graphene synthesized on a laboratory scale and an industrial scale. Here, recent progress toward the mass production of CVD graphene films is summarized, including the manufacturing process, equipment, and critical process parameters. Moreover, the large-scale homogeneity of graphene films and fast characterization methods are also discussed, which are crucial for quality control in mass production. PMID- 30277602 TI - Prokineticin-2 promotes chemotaxis and alternative A2 reactivity of astrocytes. AB - Astrocyte reactivity is disease- and stimulus-dependent, adopting either a proinflammatory A1 phenotype or a protective, anti-inflammatory A2 phenotype. Recently, we demonstrated, using cell culture, animal models and human brain samples, that dopaminergic neurons produce and secrete higher levels of the chemokine-like signaling protein Prokineticin-2 (PK2) as a compensatory protective response against neurotoxic stress. As astrocytes express a high level of PK2 receptors, herein, we systematically characterize the role of PK2 in astrocyte structural and functional properties. PK2 treatment greatly induced astrocyte migration, which was accompanied by a shift in mitochondrial energy metabolism, a reduction in proinflammatory factors, and an increase in the antioxidant genes Arginase-1 and Nrf2. Overexpression of PK2 in primary astrocytes or in the in vivo mouse brain induced the A2 astrocytic phenotype with upregulation of key protective genes and A2 reactivity markers including Arginase 1 and Nrf2, PTX3, SPHK1, and TM4SF1. A small-molecule PK2 agonist, IS20, not only mimicked the protective effect of PK2 in primary cultures, but also increased glutamate uptake by upregulating GLAST. Notably, IS20 blocked not only MPTP induced reductions in the A2 phenotypic markers SPHK1 and SCL10a6 but also elevation of the of A1 marker GBP2. Collectively, our results reveal that PK2 regulates a novel neuron-astrocyte signaling mechanism by promoting an alternative A2 protective phenotype in astrocytes, which could be exploited for development of novel therapeutic strategies for PD and other related chronic neurodegenerative diseases. PK2 signals through its receptors on astrocytes and promotes directed chemotaxis. PK2-induced astrocyte reactivity leads to an increase in antioxidant and anti-inflammatory proteins while increasing glutamate uptake, along with decreased inflammatory factors.

AB - Diarylamine-substituted osmanaphthalyne complexes that feature two redox centers linked by the rigid skeleton of the metallacycle (C^C+ ), specifically, [OsCl2 (PPh3 )2 {(C^C+ )NAr2 }][BF4 - ] (Ar=Ph (1 a), p-MeOPh (1 b)) and their open-ring precursors [OsHCl2 (PPh3 )2 {(=C-C(PPh3 + )=CHPh)NR2 }][BF4 - ] (Ar=Ph (2 a), p MeOPh (2 b)), were successfully synthesized and characterized by 1 H, 13 C, and 31 P NMR spectroscopy, ESI-MS, and elemental analysis. The solid-state molecular structures of complexes 1 a and 2 a were ascertained by single-crystal X-ray diffraction. The Os=C bond length in both complexes 1 a and 2 a fell within the range reported for similar osmanaphthalynes and osmium carbyne complexes, respectively. The structural parameters determined for complex 1 a, which were successfully reproduced by theoretical calculations, point to a pi-delocalized metallacycle structure. The purple color of compounds 1 a and b was explained by the diarylamine->Os(metallacycle) charge-transfer absorption in the visible region. The neutral, one-electron-oxidized and one-electron-reduced states of compounds 1 a, b, and a reference complex that lacked the diarylamine substituent, [OsCl2 (PPh3 )2 {(C^C+ )}][BF4 - ] (1'), were investigated by cyclic and square-wave voltammetry, UV/Vis/NIR spectroelectrochemistry, and DFT calculations. The spin density in singly oxidized complexes [1 a]+ and [1 b]+ predominantly resided on the aminyl segment, with osmium involvement controlled by the diphenylamine substitution. Spin density in stable, singly-reduced [1']- was distributed mainly over the osmanaphthalyne metallacycle. PMID- 30277606 TI - An In Situ Reversible Heterodimeric Nanoswitch Controlled by Metal-Ion-Ligand Coordination Regulates the Mechanosensing and Differentiation of Stem Cells. AB - In situ and cytocompatible nanoswitching by external stimuli is highly appealing for reversibly regulating cellular adhesion and functions in vivo. Here, a heterodimeric nanoswitch is designed to facilitate in situ switchable and combinatorial presentation of integrin-binding cell-adhesive moieties, such as Mg2+ and Arg-Gly-Asp (RGD) ligand in nanostructures. In situ reversible nanoswitching is controlled by convertible coordination between bioactive Mg2+ and bisphosphonate (BP) ligand. A BP-coated gold-nanoparticle monomer (BP-AuNP) on a substrate is prepared to allow in situ assembly of cell-adhesive Mg2+ active Mg-BP nanoparticles (NPs) on a BP-AuNP surface via Mg2+ -BP coordination, yielding heterodimeric nanostructures (switching "ON"). Ethylenediaminetetraacetic acid (EDTA)-based Mg2+ chelation allows in situ disassembly of Mg2+ -BP NP, reverting to Mg2+ -free monomer (switching "OFF"). This in situ reversible nanoswitching on and off of cell-adhesive Mg2+ presentation allows reversible cell adhesion and release in vivo, respectively, and spatiotemporally controls cyclic cell adhesion. In situ heterodimeric assembly of dual RGD ligand- and Mg2+ -active RGD-BP-Mg2+ NP (switching "Dual ON") further tunes and promotes focal adhesion, spreading, and differentiation of stem cells. The modular nature of this in situ nanoswitch can accommodate various bioactive nanostructures via metal-ion-ligand coordination to regulate diverse cellular functions in vivo in reversible and compatible manner. PMID- 30277603 TI - Resting-state basal ganglia network codes a motor musical skill and its disruption From dystonia. AB - BACKGROUND: Musician's dystonia critically impacts professional musicians' careers as they may lose musical skills, which have been acquired through long and intensive training. Yet the pathophysiology of musician's dystonia and its link to the neural mechanisms supporting musical skills is poorly understood. We tested if resting-state functional connectivity might reflect an aspect of musical skill linked to the pathophysiology of musician's dystonia. We also tested a second hypothesis that the region with altered resting-state functional connectivity might be correlated with a quantitative measure of musical skills. METHODS: We studied 21 patients with musician's dystonia affecting their hands and 34 healthy musicians, using resting-state functional magnetic resonance imaging and behavioral assessment. We tested between-group differences of resting state functional connectivity throughout the whole brain using independent component analysis. RESULTS: We found abnormal basal ganglia resting-state functional connectivity in the putamina of patients with musician's dystonia compared with those of healthy musicians (P = 0.035 corrected for multiple comparisons). We also found that the temporal precision of keystrokes was correlated with basal ganglia functional connectivity in the putamina of healthy pianists (r = 0.72, P = 0.0005), but not in pianists with musician's dystonia (r = -0.11, P = 0.64). CONCLUSIONS: We show that abnormalities of the putamen exist even at rest in musician's dystonia, whereas putaminal abnormality has previously been reported during a task. Moreover, basal ganglia resting-state functional connectivity in the putamen represented training levels in healthy musicians, and its disruption was associated with musician's dystonia. This novel finding hints at the pathophysiological mechanisms by which musician's dystonia follows extensive musical training. (c) 2018 The Authors.

PMID- 30277608 TI - Compelling Rejuvenated Catalytic Performance in Metallic Glasses. AB - Metallic glasses (MGs) with the metastable nature and random atomic packing structure have attracted large attention in the catalytic family due to their superior catalytic performance. In contrast, their crystalline counterparts are restricted by the highly ordered packing structure, fewer surface active sites, and crystallographic defects for catalytic activity. The uncertainty of the different catalytic mechanisms and the intrinsic characteristics correlated to MGs and their crystalline counterparts become a major impediment to promote their catalytic efficiencies and widespread applications. Herein, it is reported that the excellent catalytic behavior in Fe-based MGs goes through a detrimental effect with the partial crystallization, but receives a compelling rejuvenation in the full crystallization. Further investigation reveals that multiphase intermetallics with electric potential differences in fully crystallized alloys facilitate the formation of galvanic cells. More importantly, extensively reduced grain boundaries due to grain growth greatly weaken electron trapping and promote inner electron transportation. The relatively homogenous grain-boundary corrosion in the intermetallics contributes to well-separated phases after reaction, leading to refreshment of the surface active sites, thereby quickly activating hydrogen peroxide and rapidly degrading organic pollutants. The exploration of catalytic mechanisms in the crystalline counterparts of MGs provides significant insights into revolutionize novel catalysts. PMID- 30277607 TI - Inhibition of hematopoietic cell kinase dysregulates microglial function and accelerates early stage Alzheimer's disease-like neuropathology. AB - Emerging evidence have posited that dysregulated microglia impair clearance and containment of amyloid-beta (Abeta) species in the brain, resulting in aberrant buildup of Abeta and onset of Alzheimer's disease (AD). Hematopoietic cell kinase (Hck) is one of the key regulators of phagocytosis among the Src family tyrosine kinases (SFKs) in myeloid cells, and its expression is found to be significantly altered in AD brains. However, the role of Hck signaling in AD pathogenesis is unknown. We employed pharmacological inhibition and genetic ablation of Hck in BV2 microglial cells and J20 mouse model of AD, respectively, to evaluate the impact of Hck deficiency on Abeta-stimulated microglial phagocytosis, Abeta clearance, and resultant AD-like neuropathology. Our in vitro data reveal that pharmacological inhibition of SFKs/Hck in BV2 cells and genetic ablation of their downstream kinase, spleen tyrosine kinase (Syk), in primary microglia significantly attenuate Abeta oligomers-stimulated microglial phagocytosis. Whereas in Hck-deficient J20 mice, we observed exacerbated Abeta plaque burden, reduced microglial coverage, containment, and phagocytosis of Abeta plaques, and induced iNOS expression in plaque-associated microglial clusters. These multifactorial changes in microglial activities led to attenuated PSD95 levels in hippocampal DG and CA3 regions, but did not alter the postsynaptic dendritic spine morphology at the CA1 region nor cognitive function of the mice. Hck inhibition thus accelerates early stage AD-like neuropathology by dysregulating microglial function and inducing neuroinflammation. Our data implicate that Hck pathway plays a prominent role in regulating microglial neuroprotective function during the early stage of AD development. PMID- 30277609 TI - A Cryogenic Process for Antisolvent-Free High-Performance Perovskite Solar Cells. AB - A cryogenic process is introduced to control the crystallization of perovskite layers, eliminating the need for the use of environmentally harmful antisolvents. This process enables decoupling of the nucleation and the crystallization phases by inhibiting chemical reactions in as-cast precursor films rapidly cooled down by immersion in liquid nitrogen. The cooling is followed by blow-drying with nitrogen gas, which induces uniform precipitation of precursors due to the supersaturation of precursors in the residual solvents at very low temperature, while at the same time enhancing the evaporation of the residual solvents and preventing the ordered precursors/perovskite from redissolving into the residual solvents. Using the proposed techniques, the crystallization process can be initiated after the formation of a uniform precursor seed layer. The process is generally applicable to improve the performance of solar cells using perovskite films with different compositions, as demonstrated on three different types of mixed halide perovskites. A champion power conversion efficiency (PCE) of 21.4% with open-circuit voltage (VOC ) = 1.14 V, short-circuit current density ( JSC ) = 23.5 mA cm-2 , and fill factor (FF) = 0.80 is achieved using the proposed cryogenic process. PMID- 30277611 TI - Cucurbitacin I induces cancer cell death through the endoplasmic reticulum stress pathway. AB - Endoplasmic reticulum stress (ERS) is usually involved in tumor development and progression, and anticancer agents have recently been recognized to induce ERS. Cucurbitacin-I showed a potent anticancer action by inducing apoptosis through the inhibition of signal transducer and activator of transcription 3 pathway and triggering autophagic cell death. It is not known whether ERS mediates the cancer cell death induced by cucurbitacin-I. Here, we investigated the role of ERS in cucurbitacin-I-treated SKOV3 ovarian cancer cells and PANC-1 pancreatic cancer cells. We confirmed that cucurbitacin-I caused cell death and stirred excessive ERS levels by activating inositol requiring enzyme 1alpha (IRE1alpha) and protein kinase R-like endoplasmic reticulum kinase (PERK), as well as PERK downstream factors, including IRE1alpha and C/EBP homologous protein, but not activating transcription factor 6 (ATF6alpha) pathway, which was in parallel with the increased Bax and caspase-12-dependent ERS-associated apoptosis, autophagy and autophagy flux levels and caspase-independent nonapoptotic cell death. Furthermore, 4-phenylbutyrate, an ERS inhibitor, suppressed cucurbitacin-I induced apoptosis, autophagy, autophagy flux, and autophagic cell death. Simultaneously, there are positive correlations among ERS and cucurbitacin-I induced reactive oxygen species and Ca 2+. Our results suggested that cucurbitacin-I-induced cancer cell death through the excessive ERS and CHOP-Bax and caspase-12-dependent ERS-associated apoptosis, as well as ERS-dependent autophagy, autophagy flux, and caspase-independent nonapoptotic cell death. These novel signaling insights may be useful for developing new, effective anticancer strategies in oncotherapy. PMID- 30277612 TI - Astragaloside suppresses tumor necrosis factor receptor-associated factor 5 signaling pathway and alleviates neurodegenerative changes in retinal pigment epithelial cells induced by isoflurane. AB - Epidemiological studies showed that isoflurane, a general anesthetic widely used in surgery including those for the children, is associated with impairment of neurodevelopment and neurodegenerative diseases, such as Alzheimer's disease (AD) and age-related macular degeneration (AMD), which are related to the accumulation of reactive oxygen species (ROS). Astragaloside (AS) is an antioxidant derivative from a traditional Chinese herbal medicine Astragalus membraneaceus Bunge. In this study, we used retinal pigment epithelial cells, which share plenty of features with neurodegenerative diseases such as AD and AMD to investigate the effect of AS. Cell cycle re-entry and proapoptosis were seen in retinal pigment epithelium (RPE) cells treated with isoflurane, which was alleviated by pretreatment of AS. Further, tumor necrosis factor receptor-associated factor 5 (TRAF5) and downstream nuclear factor-kappaB (NF-kappaB) were investigated to elucidate the molecular mechanism underlying protective effect of AS. RPE cells exposed to isoflurane expressed higher TRAF5 and NF-kappaB than those pretreated with AS, suggesting a critical role of TRAF5 therein. In Morris water maze (MWM) assay, Sprague-Dawley rats pretreated with AS and then exposed to isoflurane spent less time in swimming to the platform, and their TRAF5 expression was significantly lower than those received anesthesia alone. Further studies on the consequence of forced downregulation or upregulation are warranted that may employ cutting-edge technologies such as optogenetics to overcome the difficulties in manipulating expression of TRAF5. Although the link between TRAF5 and neurodegeneration requires more in-depth investigations, our study provide a novel hint on the pathological mechanism of isoflurane and suggest a potential target for eliminating persistent side effect of anesthesia. PMID- 30277610 TI - Systems Thinking as a Framework for Analyzing Commercial Determinants of Health. AB - : Policy Points: Worldwide, more than 70% of all deaths are attributable to noncommunicable diseases (NCDs), nearly half of which are premature and apply to individuals of working age. Although such deaths are largely preventable, effective solutions continue to elude the public health community. One reason is the considerable influence of the "commercial determinants of health": NCDs are the product of a system that includes powerful corporate actors, who are often involved in public health policymaking. This article shows how a complex systems perspective may be used to analyze the commercial determinants of NCDs, and it explains how this can help with (1) conceptualizing the problem of NCDs and (2) developing effective policy interventions. CONTEXT: The high burden of noncommunicable diseases (NCDs) is politically salient and eminently preventable. However, effective solutions largely continue to elude the public health community. Two pressing issues heighten this challenge: the first is the public health community's narrow approach to addressing NCDs, and the second is the involvement of corporate actors in policymaking. While NCDs are often conceptualized in terms of individual-level risk factors, we argue that they should be reframed as products of a complex system. This article explores the value of a systems approach to understanding NCDs as an emergent property of a complex system, with a focus on commercial actors. METHODS: Drawing on Donella Meadows's systems thinking framework, this article examines how a systems perspective may be used to analyze the commercial determinants of NCDs and, specifically, how unhealthy commodity industries influence public health policy. FINDINGS: Unhealthy commodity industries actively design and shape the NCD policy system, intervene at different levels of the system to gain agency over policy and politics, and legitimize their presence in public health policy decisions. CONCLUSIONS: It should be possible to apply the principles of systems thinking to other complex public health issues, not just NCDs. Such an approach should be tested and refined for other complex public health challenges. PMID- 30277613 TI - MiR-125b suppresses the carcinogenesis of osteosarcoma cells via the MAPK-STAT3 pathway. AB - The microRNA (miRNA) miR-125b is abnormally expressed in many different types of tumors, including osteosarcoma (OS). How aberrantly expressed miR-125b participates in regulating the initiation and progression of OS is still poorly understood. In the current study, we found that in OS, miR-125b can suppress the expression of MAP kinase kinase 7 (MKK7), which can dephosphorylate and inactivate signal transducer and activator of transcription 3 (STAT3). We also identified an elevated expression level of MKK7 in OS and an association between MKK7 expression and poor prognosis. Further, miR-125b inhibited OS cell proliferation and invasion by targeting and downregulating MKK7 in vitro and suppressed tumor formation in vivo. Moreover, using Western blot analysis, we preliminarily proved that the activation (phosphorylation) of STAT3 was regulated by MKK7 at the epigenetic level. MKK7 was overexpressed in OS and associated with poor clinical results. The miR-125b-MAPK-STAT3 axis may be one of the mechanisms of OS oncogenesis and a potential target for the treatment of OS.

AB - In the last few decades, N-heterocyclic carbene (NHC) ligands, characterized by attractive features, have increased their presence in transition-metal catalysis. However, chiral NHC ligands still require further design enhancement to realize far more exciting synthetic applications. This review documents advances in chiral NHC ligands, focusing on planar-chiral ferrocene-based NHCs. As the basic shape of most classes of NHC rings is planar, it seems rational to employ a planar-chiral element in the design of chiral NHC ligands. PMID- 30277616 TI - Tissue protein and lipid alterations in response to metallic impaction. AB - Tissue response to metallic contact and injury remains poorly understood at the level of proteins and lipid changes. We used corneas as a model system (bovine, porcine [n = 300 each], and human corneas [n = 6]) to characterize proteomic and lipidomic reactions to metallic exposure (impaction with iron). We also made a limited investigation into protein extractability and profile changes due to copper, and lead exposure as well. We identified selected proteins after trypsin digestion using an LCQ Deca XP and lipids using a TSQ Quantum Access Max mass spectrometer, respectively. Our findings indicate that iron impaction to corneal tissue results in cleavage of 1-phosphatidylinositol-4,5-bisphosphate phosphodiesterase beta-2 variant (PLCB2; 134 kDa) into a 36 kDa species and presence of the epithelial layer is necessary for this cleavage. Penetration of the cornea with other metals (copper and lead) resulted in lower protein extractability from corneal tissue compared with controls but not distinct changes in PLCB2. The changes in protein profiles were unique to the type of metal used for impaction. The depth of injury negatively affected protein extractability and profile compared with controls. These changes were also dependent on several other factors in a complex manner. Iron impaction of corneal tissue for 24 hours results in cleavage of PLCB2 commensurate with significant changes in phosphatidylinositols but not phosphatidylcholines or other phospholipids. PMID- 30277618 TI - An update and expansion on the role of the Violence Risk Appraisal Guide and Historical Clinical Risk Management-20 in United States case law. AB - An individual's risk for future violent behavior may be considered in various legal contexts, including civil commitment, criminal sentencing, or suitability for parole. Among the assessment tools forensic evaluators use to assess violence risk are the Violence Risk Appraisal Guide (VRAG; Quinsey, Harris, Rice, & Cormier, ) and the Historical Clinical Risk Managment-20 (HCR-20)/Historical Clinical Risk Management-20, Version 3 (HCR-20V3 ) (Webster, Douglas, Eaves, & Hart, and Douglas, Hart, Webster, & Belfrage, , respectively). Previous surveys and case law research suggest that these measures are widely used and perceived to be useful in aiding forensic clinicians. This study provides an update to Vitacco, Erickson, Kurus, and Apple () and examines the use of the HCR-20 and VRAG in United States case law. A LexisNexis review revealed 134 cases decided between 1 January 2010 and 21 December 2016 that included the HCR-20, VRAG, or both. Results revealed that these measures are typically introduced by the prosecution to inform opinions regarding general violence risk. In addition, consistent with previous research, these data suggest the introduction of the HCR 20 and VRAG is rarely challenged and, when challenged, these challenges are rarely successful. However, data suggest that courts and parole boards may focus on specific risk factors (e.g., lack of insight) at the expense of other, more objective factors. Finally, we offer suggestions for clinicians who have transitioned to the newest version of the HCR-20. PMID- 30277614 TI - Genome-wide interaction studies identify sex-specific risk alleles for nonsyndromic orofacial clefts. AB - Nonsyndromic cleft lip with or without cleft palate (NSCL/P) is the most common craniofacial birth defect in humans and is notable for its apparent sexual dimorphism where approximately twice as many males are affected as females. The sources of this disparity are largely unknown, but interactions between genetic and sex effects are likely contributors. We examined gene-by-sex (G * S) interactions in a worldwide sample of 2,142 NSCL/P cases and 1,700 controls recruited from 13 countries. First, we performed genome-wide joint tests of the genetic (G) and G * S effects genome-wide using logistic regression assuming an additive genetic model and adjusting for 18 principal components of ancestry. We further interrogated loci with suggestive results from the joint test ( p < 1.00 * 10 -5 ) by examining the G * S effects from the same model. Out of the 133 loci with suggestive results ( p < 1.00 * 10 -5 ) for the joint test, we observed one genome-wide significant G * S effect in the 10q21 locus (rs72804706; p = 6.69 * 10 -9 ; OR = 2.62 CI [1.89, 3.62]) and 16 suggestive G * S effects. At the intergenic 10q21 locus, the risk of NSCL/P is estimated to increase with additional copies of the minor allele for females, but the opposite effect for males. Our observation that the impact of genetic variants on NSCL/P risk differs for males and females may further our understanding of the genetic architecture of NSCL/P and the sex differences underlying clefts and other birth defects. PMID- 30277617 TI - Engineering Anisotropic Muscle Tissue using Acoustic Cell Patterning. AB - Tissue engineering has offered unique opportunities for disease modeling and regenerative medicine; however, the success of these strategies is dependent on faithful reproduction of native cellular organization. Here, it is reported that ultrasound standing waves can be used to organize myoblast populations in material systems for the engineering of aligned muscle tissue constructs. Patterned muscle engineered using type I collagen hydrogels exhibits significant anisotropy in tensile strength, and under mechanical constraint, produced microscale alignment on a cell and fiber level. Moreover, acoustic patterning of myoblasts in gelatin methacryloyl hydrogels significantly enhances myofibrillogenesis and promotes the formation of muscle fibers containing aligned bundles of myotubes, with a width of 120-150 um and a spacing of 180-220 um. The ability to remotely pattern fibers of aligned myotubes without any material cues or complex fabrication procedures represents a significant advance in the field of muscle tissue engineering. In general, these results are the first instance of engineered cell fibers formed from the differentiation of acoustically patterned cells. It is anticipated that this versatile methodology can be applied to many complex tissue morphologies, with broader relevance for spatially organized cell cultures, organoid development, and bioelectronics. PMID- 30277619 TI - Multivalent Fucosides with Nanomolar Affinity for the Aspergillus fumigatus Lectin FleA Prevent Spore Adhesion to Pneumocytes. AB - FleA (or AFL), a fucose lectin, was recently identified in the opportunistic mold Aspergillus fumigatus, which causes fatal lung infections in immunocompromised patients. We designed di-, hexa- and octavalent fucosides with various spacer arm lengths to block the hexameric FleA through chelation. Microcalorimetry measurements showed that the ethylene glycol (EG) spacer arm length has a strong influence on the binding affinity of the divalent fucosides. The relationship between the EG length and chelate binding efficiency to FleA was explored according to polymer theory. Hexa- and octavalent compounds based on cyclodextrin and octameric silsesquioxane scaffolds were nanomolar FleA inhibitors, surpassing their monovalent fucose analogue by more than three orders of magnitude. Importantly, some of the fucosides were highly efficient in preventing fungal spore adhesion to bronchoepithelial cells, with half maximal inhibitory concentration values in the micromolar range. We propose that the synergistic antiadhesive effect observed can be ascribed to chelate binding to FleA and to the formation of conidium aggregates, as observed by optical microscopy. These fucosides are promising tools that can be used to better understand the role of FleA in conidia pathogenicity and host defenses against invasive aspergillosis.

AB - A series of symmetric squarylium dyes (SQDPA-X) with different halogen (X = F, Cl, Br, I) substituents have been developed. The photophysical properties could be facilely tuned by the halogen modulation effects. The strategy of incorporating different halogen substitutions into AIE active luminogens enables a facile approach for exploring new intriguing organic fluorescent dyes. PMID- 30277621 TI - Syncytial isopotentiality: A system-wide electrical feature of astrocytic networks in the brain. AB - Syncytial isopotentiality, resulting from a strong electrical coupling, emerges as a physiological mechanism that coordinates individual astrocytes to function as a highly efficient system in brain homeostasis. However, whether syncytial isopotentiality occurs selectively to certain brain regions or is universal to astrocytic networks remains unknown. Here, we have explored the correlation of syncytial isopotentiality with different astrocyte subtypes in various brain regions. Using a nonphysiological K+-free/Na+ electrode solution to depolarize a recorded astrocyte in situ, the existence of syncytial isopotentiality can be revealed: the recorded astrocyte's membrane potential remains at a quasi physiological level due to strong electrical coupling with neighboring astrocytes. Syncytial isopotentiality appears in Layer I of the motor, sensory, and visual cortical regions, where astrocytes are organized with comparable cell densities, interastrocytic distances, and the quantity of directly coupled neighbors. Second, though astrocytes vary in their cytoarchitecture in association with neuronal circuits from Layers I-VI, the established syncytial isopotentiality remains comparable among different layers in the visual cortex. Third, neurons and astrocytes are uniquely organized as barrels in Layer IV somatosensory cortex; interestingly, astrocytes both inside and outside of the barrels do electrically communicate with each other and also share syncytial isopotentiality. Fourth, syncytial isopotentiality appears in radial-shaped Bergmann glia and velate astrocytes in the cerebellar cortex. Fifth, although fibrous astrocytes in white matter exhibit a distinct morphology, their network syncytial isopotentiality is comparable with protoplasmic astrocytes. Altogether, syncytial isopotentiality appears as a system-wide electrical feature of astrocytic networks in the brain. PMID- 30277622 TI - The role of the arcuate and middle longitudinal fasciculi in speech perception in noise in adulthood. AB - In this article, we used High Angular Resolution Diffusion Imaging (HARDI) with advanced anatomically constrained particle filtering tractography to investigate the role of the arcuate fasciculus (AF) and the middle longitudinal fasciculus (MdLF) in speech perception in noise in younger and older adults. Fourteen young and 15 elderly adults completed a syllable discrimination task in the presence of broadband masking noise. Mediation analyses revealed few effects of age on white matter (WM) in these fascicles but broad effects of WM on speech perception, independently of age, especially in terms of sensitivity and criterion (response bias), after controlling for individual differences in hearing sensitivity and head size. Indirect (mediated) effects of age on speech perception through WM microstructure were also found, after controlling for individual differences in hearing sensitivity and head size, with AF microstructure related to sensitivity, response bias and phonological priming, and MdLF microstructure more strongly related to response bias. These findings suggest that pathways of the perisylvian region contribute to speech processing abilities, with relatively distinct contributions for the AF (sensitivity) and MdLF (response bias), indicative of a complex contribution of both phonological and cognitive processes to age-related speech perception decline. These results provide new and important insights into the roles of these pathways as well as the factors that may contribute to elderly speech perception deficits. They also highlight the need for a greater focus to be placed on studying the role of WM microstructure to understand cognitive aging. PMID- 30277623 TI - Direct and cascading effects of landscape structure on tropical forest and non forest frugivorous birds. AB - Global biodiversity is increasingly threatened by land-use change, but the direct and indirect drivers of species diversity in human-modified tropical landscapes are poorly known. Forest-dependent species are expected to be particularly sensitive to changes in landscape composition (e.g., forest loss) and configuration (e.g., increase of forest edges), both directly and indirectly through cascading landscape effects on local patterns of forest structure and resource availability. In contrast, non-forest-dependent species are probably more strongly related to landscape changes than to local forest patterns, as these species are able to use resources not only from the forest, but also from other landscape elements over larger spatial scales. We tested these hypotheses using structural equation modeling. In particular, we sampled 20 landscapes (115 ha each) from the Brazilian Atlantic rainforest to assess the effect of landscape scale forest cover and amount of forest edges on the diversity of frugivorous birds, both directly and indirectly through the effect that these landscape variables may have on vegetation complexity and fruit biomass. We separately assessed the response of forest-dependent and non-forest-dependent frugivores to infer potential mechanisms underlying bird assemblages in fragmented landscapes. The diversity of forest-dependent birds mainly decreased with the simplification of vegetation complexity in more deforested landscapes, but increased with increasing fruit biomass in more forested landscapes (indirect effects). Both patterns were significant, thus supporting a strong bottom-up control, i.e., local habitat simplification and resource scarcity in highly deforested landscapes limits the maintenance of forest-dependent birds. Conversely, but as expected, non-forest-dependent birds were more strongly and directly related to landscape-scale patterns. In particular, landscapes with higher forest edge amount showed higher bird species diversity, probably because the increasing length of ecotones and interspersion/juxtaposition of different habitat types in landscapes with more forest edges can increase resource availability and foraging efficiency of non-forest-dependent birds. As the seed dispersal services offered by forest-dependent species cannot be ecologically compensated for by the proliferation of non-forest-dependent species, preventing forest loss is imperative to maintain forest-dependent birds and forest regeneration in this vanishing biodiversity hotspot. PMID- 30277624 TI - Adaptation of brain functional stream architecture in athletes with fast demands of sensorimotor integration. AB - Training-induced neuroplasticity has been described in athletes' population. However, it remains largely unknown how regular training and sports proficiency modifies neuronal circuits in the human brain. In this study, we used voxel-based morphometry and stepwise functional connectivity (SFC) analyses to uncover connectivity changes in the functional stream architecture in student-athletes at early stages of sensorimotor skill training. Thirty-two second-year student athletes whose major was little-ball sports and thirty-four nonathlete controls were recruited for the study. We found that athletes showed greater gray matter volume in the right sensorimotor area, the limbic lobe, and the anterior lobe of the cerebellum. Furthermore, SFC analysis demonstrated that athletes displayed significantly smaller optimal connectivity distance from those seed regions to the dorsal attention network (DAN) and larger optimal connectivity distance to the default mode network (DMN) compared to controls. The Attention Network Test showed that the reaction time of the orienting attention subnetwork was positively correlated with SFC between the seeds and the DAN, while negatively correlated with SFC between the seeds and the DMN. Our findings suggest that neuroplastic adaptations on functional connectivity streams after motor skill training may enable novel information flow from specific areas of the cortex toward distributed networks such as the DAN and the DMN. This could potentially regulate the focus of external and internal attention synchronously in athletes, and consequently accelerate the reaction time of orienting attention in athletes. PMID- 30277625 TI - Course and stability of cognitive and metacognitive beliefs in depression. AB - Maladaptive cognitive beliefs as measured by the Dysfunctional Attitudes Scale (DAS) increase vulnerability to depression. Maladaptive metacognitive beliefs as measured by the Metacognitive Questionnaire-30 (MCQ-30) are also thought to contribute to depression. However, the long-term stability of metacognitive beliefs in depression has not yet been investigated. It is unclear whether metacognitive beliefs can add explanatory power to depression above and beyond maladaptive cognitive beliefs. The aim of the present study was to investigate the role and stability of cognitive and metacognitive maladaptive beliefs in depression. Eighty-four patients with depression were assessed with the DAS, three subscales of the MCQ-30 (positive metacognitive beliefs about worry and rumination [PB]; negative metacognitive beliefs about the uncontrollability of rumination [NB]; metacognitive beliefs concerning the need to control one's thoughts [NFC]), the Hamilton Depression Rating Scale, and the Beck Depression Inventory at baseline and were reassessed 3.5 years later. Analyses using a longitudinal latent growth model showed that change on the DAS and baseline scores and change on the MCQ-30 (NB and NFC) significantly predicted change in self-rated depressive symptoms over 3.5 years. However, the DAS explained more additional variance than the integration of the MCQ-30 subscales. Subscales of the MCQ-30 were more stable than the DAS. Although cognitive and metacognitive maladaptive beliefs were both predictors of depression, the DAS was a better predictor than the MCQ-30 subscales. Nevertheless, because maladaptive metacognitive beliefs were more stable than maladaptive cognitive beliefs, they should be considered an important underlying vulnerability factor for depression. PMID- 30277626 TI - Helicobacter: Inflammation, immunology, and vaccines. AB - Helicobacter pylori infection induces a chronic gastric inflammation which can lead to gastric ulcers and cancer. The mucosal immune response to H. pylori is first initiated by the activation of gastric epithelial cells that respond to numerous bacterial factors, such as the cytotoxin-associated gene A or the lipopolysaccharide intermediate heptose-1,7-bisphosphate. The response of these cells is orchestrated by different receptors including the intracellular nucleotide-binding oligomerization domain-containing protein 1 or the extracellular epidermal growth factor receptor. This nonspecific response leads to recruitment and activation of various myeloid (macrophages and dendritic cells) and T cells (T helper-17 and mucosal-associated invariant T cells), which magnify and maintain inflammation. In this review, we summarize the major advances made in the past year regarding the induction, the regulation, and the role of the innate and adaptive immune responses to H. pylori infection. We also recapitulate efforts that have been made to develop efficient vaccine strategies. PMID- 30277627 TI - Randomized trial of the efficacy of intravaginal ulinastatin administration for the prevention of preterm birth in women with a singleton pregnancy and both cervical shortening and inflammation of lower genital tract. AB - AIM: To assess the preventive effect on preterm birth of intravaginal ulinastatin (urinary trypsin inhibitor; UTI) administration during the mid-trimester in women with singleton pregnancy and both cervical shortening and lower genital infections. METHODS: Pregnant women with a short cervical length < 25 mm between 16 and 26 weeks of gestation and who had been diagnosed with a lower genital infection were randomly assigned for intravaginal UTI administration or placebo. All of the women were screened for infection or inflammation of the lower genital tract, and women with negative results were excluded. RESULTS: Of the 92 patients with a short cervical length who were assessed for eligibility for this study, 86 singleton patients were enrolled. All patients were randomized to one of two treatment groups: patients administered UTI (n = 35) and placebo (n = 35). There were no differences between the two groups in the incidence of preterm delivery before 28, 30, 32, 34 and 37 weeks of gestation and in perinatal outcomes. CONCLUSION: For women diagnosed with a short cervical length < 25 mm) between 16 and 26 weeks of gestation and lower genital infection, who were at risk of preterm birth, administration of transvaginal UTI with vaginal irrigation showed no apparent benefit. Future research on the efficacy of UTI should evaluate modified modes of UTI application. PMID- 30277628 TI - Volumetric Apparent Diffusion Coefficient Histogram Analysis in Differentiating Intrahepatic Mass-Forming Cholangiocarcinoma From Hepatocellular Carcinoma. AB - BACKGROUND: Accurate differentiation between intrahepatic mass-forming cholangiocarcinoma (IMCC) and hepatocellular carcinoma (HCC) is needed because treatment and prognosis differ significantly. PURPOSE: To explore whether volumetric apparent diffusion coefficient (ADC) histogram analysis can provide additional value to dynamic enhanced MRI in differentiating IMCC from HCC. STUDY TYPE: Retrospective. POPULATION: In all, 131 patients with pathologically proven IMCC (n = 33) or HCC (n = 98). FIELD STRENGTH/SEQUENCE: 3.0T MRI/conventional T1 weighted imaging (T1WI), T2WI, and diffusion-weighted imaging (DWI) with b value of 800 sec/mm2, dynamic enhanced MRI with gadobenate dimeglumine. ASSESSMENT: Dynamic enhanced MR images were analyzed by two independent reviewers using a five-point scale to determine the diagnosis. Volumetric ADC assessments were performed independently by two radiologists to obtain different histogram parameters for each lesion. Quantitative histogram parameters were compared between the IMCC group and HCC group. Diagnostic performance of dynamic enhanced MRI, volumetric ADC histogram analysis, and the combination of both were analyzed. STATISTICAL TESTS: Intraclass correlation coefficient (ICC) analysis, independent Student's t-test, or Mann-Whitney U-test, receiver operator characteristic (ROC) curves analysis, and McNemar test. RESULTS: The sensitivity and specificity for dynamic enhanced MRI to differentiate IMCC from HCC were 82.1% and 82.6%, respectively. For all volumetric ADC histogram parameters, the 75th percentile ADC (ADC75%) had the highest AUC (0.791) in differentiating IMCC from HCC, with sensitivity and specificity of 69.7% and 77.6%, respectively. When combining dynamic enhanced MRI with ADC75%, the sensitivity and specificity were 82.1% and 91.9%, respectively. Compared to dynamic enhanced MRI alone, the specificity for combined dynamic enhanced MRI and ADC75% was significantly increased (P = 0.008). DATA CONCLUSION: Volumetric ADC histogram analysis provides additional value to dynamic enhanced MRI in differentiating IMCC from HCC. LEVEL OF EVIDENCE: 3 Technical Efficacy: Stage 2 J. MAGN. RESON. IMAGING 2018. PMID- 30277629 TI - Shifted balance of dorsal versus ventral striatal communication with frontal reward and regulatory regions in cannabis-dependent males. AB - The transition from voluntary to addictive behavior is characterized by a loss of regulatory control in favor of reward driven behavior. Animal models indicate that this process is neurally underpinned by a shift in ventral-dorsal striatal control of behavior; however, this shift has not been directly examined in humans. The present resting state functional magnetic resonance imaging (fMRI) study employed a two-step approach to: (a) precisely map striatal alterations using a novel, data-driven network classification strategy combining intrinsic connectivity contrast with multivoxel pattern analysis and, (b) to determine whether a ventral to dorsal striatal shift in connectivity with reward and regulatory control regions can be observed in abstinent (28 days) male cannabis dependent individuals (n = 24) relative to matched controls (n = 28). Network classification revealed that the groups can be reliably discriminated by global connectivity profiles of two striatal regions that mapped onto the ventral (nucleus accumbens) and dorsal striatum (caudate). Subsequent functional connectivity analysis demonstrated a relative shift between ventral and dorsal striatal communication with fronto-limbic regions that have been consistently involved in reward processing (rostral anterior cingulate cortex [ACC]) and executive/regulatory functions (dorsomedial prefrontal cortex [PFC]). Specifically, in the cannabis-dependent subjects, connectivity between the ventral striatum with the rostral ACC increased, whereas both striatal regions were uncoupled from the regulatory dorsomedial PFC. Together, these findings suggest a shift in the balance between dorsal and ventral striatal control in cannabis dependence. Similar changes have been observed in animal models and may promote the loss of control central to addictive behavior. PMID- 30277630 TI - The new neuroendocrinology-a perspective. PMID- 30277631 TI - Long-Chain Hyperbranched Polymers: Synthesis, Properties, and Applications. AB - By combining the virtues of conventional linear and hyperbranched polymers, long chain hyperbranched polymers (LCHBPs) have attracted great attention. Therefore, a comprehensive summary of the research progress of LCHBPs is presented, with a particular focus on their synthetic strategies, unique properties, and potential applications. The synthetic methodologies are rationalized into four main classes according to their construction process or mechanism, namely ABx (x >= 2), A2 + Bx (x >= 3), AB + ABx (x >= 2), and self-condensing vinyl polymerization. Some of their rheological properties, self-assembly behavior, and stimuli-response features are then discussed. Finally, the emergent applications including biomedicine, electrical conductivity, chemical sensing, and catalyst carrier, are outlined. It is anticipated that this review will stimulate more inspiration for advancing the development of this novel kind of LCHBP. PMID- 30277632 TI - Quality of online information about phase I clinical cancer trials in Sweden, Denmark and Norway. AB - Patients increasingly search for online information about clinical trials. Little is known about the quality and readability of the information in these databases. Therefore, the aim of this study was to assess the quality and readability of online information available to the public on phase I clinical cancer trials in Sweden, Denmark and Norway. A qualitative content analysis was made of 19 online trial descriptions from three public websites in Sweden, Denmark and Norway, and the readability of the documents was tested. Both the quality of the content and the readability scores were best for the Danish information. The Swedish texts were very short and were the least readable. Overall, the quality of the information was highly variable and nearly all the documents were misleading in part. Furthermore, the descriptions provided almost no information about possible adverse effects or disadvantages of study participation. This study highlights a communication problem and proposes new ways of presenting studies that are less suggestive of positive outcomes, arguing that we should be more careful to include information about adverse effects, and that the use of simple measures like readability testing can be useful as an indicator of text quality. PMID- 30277633 TI - 12/10-Helix in Mixed beta-Peptides Alternating Bicyclic and Acyclic beta-Amino Acids: Probing the Relationship between Bicyclic Side Chain and Helix Stability. AB - 12/10-Helices constitute suitable templates that can be used to design original structures. Nevertheless, they often suffer from a weak stability in polar solvents because they exhibit a mixed hydrogen-bond network resulting in a small macrodipole. In this work, stable and functionalizable 12/10-helices were developed by alternating a highly constrained beta2, 3, 3 -trisubstituted bicyclic amino acid (S)-1-aminobicyclo[2.2.2]octane-2-carboxylic acid ((S)-ABOC) and an acyclic substituted beta-homologated proteinogenic amino acid (l-beta3 hAA). Based on NMR spectroscopic analysis, it was shown that such mixed beta peptides display well-defined right-handed 12/10-helices in polar, apolar, and chaotropic solvents; that are, CD3 OH, CDCl3 , and [D6 ]DMSO, respectively. The stability of the hydrogen bonds forming the C10 and C12 pseudocycles as well as the benefit provided by the use of the constrained bicyclic ABOC versus typical acyclic beta-amino acids sequences when designing 12/10-helix were investigated using NH/ND NMR exchange experiments and DFT calculations in various solvents. These studies showed that the beta3 -hAA/(S)-ABOC helix displayed a more stable hydrogen-bond network through specific stabilization of the C10 pseudocycles involving the bridgehead NH of the ABOC bicyclic scaffold. PMID- 30277634 TI - Reversible and Tunable Photoswitching of Protein Function through Genetic Encoding of Azobenzene Amino Acids in Mammalian Cells. AB - The genetic encoding of three different azobenzene phenylalanines with different photochemical properties was achieved in human cells by using an engineered pyrrolysyl tRNA/tRNA synthetase pair. In order to demonstrate reversible light control of protein function, azobenzenes were site-specifically introduced into firefly luciferase. Computational strategies were applied to guide the selection of potential photoswitchable sites that lead to a reversibly controlled luciferase enzyme. In addition, the new azobenzene analogues provide enhanced thermal stability, high photoconversion, and responsiveness to visible light. These small-molecule photoswitches can reversibly photocontrol protein function with excellent spatiotemporal resolution, and preferred sites for incorporation can be computationally determined, thus providing a new tool for investigating biological processes. PMID- 30277635 TI - Alcohol-induced cognitive deficits are associated with decreased circulating levels of the neurotrophin BDNF in humans and rats. AB - Chronic alcohol consumption is associated with neurocognitive and memory deficits, dramatically affecting plasticity and connectivity, with maximal expression as dementia. Neurotrophic factors may contribute to alcohol-related cognitive decline. For further investigation, a cross-sectional study was performed to evaluate the association of cognitive impairment, by using frontal assessment battery, and memory loss, using memory failures everyday, with the circulating levels of the neurotrophin brain-derived neurotrophic factor (BDNF) and neurotrophin 3 (NT-3) in abstinent subjects with alcohol use disorders (AUDs, N = 58, average of 17.9 years of problematic use and 4.3 months of abstinence) compared with healthy control subjects (N = 22). This association was also explored in a pre-clinical model of adolescent rats chronically exposed to alcohol up to adulthood (~77 days old) in a three-bottle free-choice (5-10-20 percent), repeated abstinence and relapse paradigm. AUD subjects had low educational level and cognitive impairment associated with teenage consumption and lower circulating levels of BDNF and NT-3. Only BDNF concentration showed a positive correlation with frontal assessment battery in AUD patients. In the ethanol-exposed rats, the plasma levels of BDNF and NT-3 were also decreased, and a negative correlation between hippocampal Bdnf mRNA levels and recognition memory was found. The ethanol-exposed rat hippocampus showed a decrease in the mRNA levels of neurotrophic (Bdnf and Ntf-3) and neurogenic (Mki67, Sox2, Dcx, Ncam1 and Calb1) factors, associated to a deactivation of the neurogenic regulator mitogen-activated protein kinase extracellular signal-regulated kinase. Results suggest a relevant role of BDNF/extracellular signal-regulated kinase 2 signaling in alcohol-induced cognitive impairment and suggest that early alcohol exposure-derived effects on cognition are associated with neurotrophin signaling deficits. PMID- 30277636 TI - Gastric cancer: Basic aspects. AB - Despite major breakthroughs in the field of personalized medicine, gastric cancer (GC) remains a clinically challenging disease, characterized by scarce effective treatment options and the lack of reliable molecular tools for the prediction of patient outcome and response to therapy. The pronounced molecular heterogeneity that dictates the phenotypical aggressiveness of gastric neoplasms severely limits the antitumor efficacy of targeted agents brought to clinical trials, and constitutes a favorable setting for the emergence of refractory tumors exhibiting multidrug resistance. We will review the most recent advances in our understanding of GC biology, which are underlying the development and clinical testing of novel targeted therapeutic agents. We will also emphasize how their efficacy and acquired resistance relate to the aberrant molecular signatures that drive gastric malignancy.

AB - Based on a terpenoid overproduction platform in yeast for genome mining, a chimeric diterpene synthase from the endophytic fungus Colletotrichum gloeosporioides ES026 was characterized as the (5R,12R,14S)-dolasta-1(15),8-diene synthase. The absolute configuration was independently verified through the use of enantioselectively deuterated terpene precursors, which unequivocally established the predicted C1-III-IV cyclization mode for this first characterized clade II-D enzyme. Extensive isotopic labeling experiments and isolation of the intermediate (1R)-delta-araneosene supported the proposed cyclization mechanism.

AB - Layered two-dimensional (2D) materials have been establish as the most significant topic in materials science for the current decade, arising to their unique physical and chemical properties. From mono-element (graphene, phosphorene, etc.) to the more commonly found containing two (metal dichalcogenides) or even further elements. A distinctive class of 2D layered materials are the metal phosphorous trichalcogenides (MPCh3, Ch=S, Se), first synthetized in the late 1800s. Having an unusual intercalation behavior, MPCh3 were intensively studied in the 1970s for their magnetism and as secondary electrodes in lithium batteries but fell under the radar, until very recently being included in the loop of 2D nanomaterials. Considering their synthesis and most significant properties, the present uprising of reports related to water splitting catalysis and energy storage in discussed in detail. This review is intended as comprehensive baseline for the anticipated new wave of researchers who aim to explore these 2D layered materials advancements in their electrochemical energy applications. PMID- 30277640 TI - Development and evaluation of a food frequency questionnaire to assess nutrient intakes of adult women in New Zealand. AB - AIM: In New Zealand, there are few adequate food frequency questionnaires for assessing dietary intake. This study aimed to develop and assess the relative validity of a multi-nutrient, culturally appropriate, semi-quantitative food frequency questionnaire for use in young adult New Zealand women (the New Zealand Women's Food Frequency Questionnaire (NZWFFQ)). METHODS: Women (n = 110) aged 16 45 years of Maori, Pacific or European ethnicity completed a NZWFFQ assessing dietary intake over the previous month, and a 4-day weighed food record. Relative validity was evaluated by comparing nutrient intakes from the NZWFFQ with the food record using Spearman's rank correlation coefficients, cross-classification, the weighted kappa statistic and Bland-Altman analysis. RESULTS: Nutrient intake was higher from the NZWFFQ compared with the food record for all nutrients (range: 1%-64% difference) except alcohol (-16% difference). Energy-adjusted correlations ranged from 0.23 to 0.67 (average 0.48). Correct classification into same and adjacent quartiles was over 70% for all nutrients except folate and vitamin D. Gross misclassification into opposite quartiles ranged from 1% (monounsaturated fat, magnesium, calcium) to 10% (iron). The weighted kappa showed poor agreement for vitamin D and folate, fair agreement for most nutrients, and moderate agreement for fibre, vitamin E, magnesium, calcium and phosphorus. CONCLUSIONS: The NZWFFQ overestimated intake of nearly all nutrients. While not suitable for assessing absolute intake, the NZWFFQ is suitable for ranking individuals based on nutrient intake demonstrating reasonable relative validity for this purpose. PMID- 30277639 TI - Outcomes in intermediate-risk pediatric lymphocyte-predominant Hodgkin lymphoma: A report from the Children's Oncology Group. AB - PURPOSE: Optimal management of patients with intermediate-risk lymphocyte predominant Hodgkin lymphoma (LPHL) is unclear due to their small numbers in most clinical trials. Children's Oncology Group AHOD0031, a randomized phase III trial of pediatric patients with intermediate-risk Hodgkin lymphoma (HL), included patients with LPHL. We report the outcomes of these patients and present directions for future therapeutic strategies. PROCEDURE: Patients received two cycles of doxorubicin, bleomycin, vincristine, etoposide, prednisone, and cyclophosphamide (ABVE-PC) followed by response evaluation. Slow early responders were randomized to two additional ABVE-PC cycles +/- two dexamethasone, etoposide, cisplatin, and cytarabine cycles and all received involved field radiotherapy (IFRT). Rapid early responders (RERs) received two additional ABVE PC cycles. RERs with complete response (CR) were randomized to IFRT or no further therapy. RERs without CR received IFRT. RESULTS: Ninety-six (5.6%) of 1711 patients on AHOD0031 had LPHL. Patients with LPHL were more likely to achieve RER (93.6% vs. 81.0%; P = 0.002) and CR (74.2% vs. 49.3%; P = 0.000005) following chemotherapy compared with patients with classical HL. Five-year event-free survival (EFS) was superior in patients with LPHL (92.2%) versus classical HL (83.5%) (P = 0.04), without difference in overall survival (OS). Among RERs with CR following chemotherapy (n = 33), there was no difference in EFS or OS between those randomized to receive or not receive IFRT. CONCLUSION: Children and adolescents with intermediate-risk LPHL represent ideal candidates for response adapted therapy based on their favorable outcomes. The majority of patients treated with the ABVE-PC backbone achieve RER with CR status and can be treated successfully without IFRT. PMID- 30277641 TI - Coronary fractional flow reserve derived from intravascular ultrasound imaging: Validation of a new computational method of fusion between anatomy and physiology. AB - OBJECTIVES: To evaluate the diagnostic performance of a novel computational algorithm based on three-dimensional intravascular ultrasound (IVUS) imaging in estimating fractional flow reserve (IVUSFR), compared to gold-standard invasive measurements (FFRINVAS). BACKGROUND: IVUS provides accurate anatomical evaluation of the lumen and vessel wall and has been validated as a useful tool to guide percutaneous coronary intervention. However, IVUS poorly represents the functional status (i.e., flow-related information) of the imaged vessel. METHODS: Patients with known or suspected stable coronary disease scheduled for elective cardiac catheterization underwent FFRINVAS measurement and IVUS imaging in the same procedure to evaluate intermediate lesions. A processing methodology was applied on IVUS to generate a computational mesh condensing the geometric characteristics of the vessel. Computation of IVUSFR was obtained from patient level morphological definition of arterial districts and from territory-specific boundary conditions. FFRINVAS measurements were dichotomized at the 0.80 threshold to define hemodynamically significant lesions. RESULTS: A total of 24 patients with 34 vessels were analyzed. IVUSFR significantly correlated (r = 0.79; P < 0.001) and showed good agreement with FFRINVAS, with a mean difference of -0.008 +/- 0.067 (P = 0.47). IVUSFR presented an overall accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of 91%, 89%, 92%, 80%, and 96%, respectively, to detect significant stenosis. CONCLUSION: The computational processing of IVUSFR is a new method that allows the evaluation of the functional significance of coronary stenosis in an accurate way, enriching the anatomical information of grayscale IVUS. PMID- 30277643 TI - Borocyclopropanation of Styrenes Mediated by UV-light Under Continuous Flow Conditions. AB - Herein, we report a user-friendly and metal-free UV-A light mediated borocyclopropanation of styrenes using continuous flow technology. A broad range of styrene derivatives can be cyclopropanated in good yields within 1 h residence time to produce highly valuable cyclopropylboronate esters with modest to good diastereoselectivities. The reaction is also applicable to alpha-substituted styrenes. Mechanistic studies support a photoredox process during which xanthone, a well-known organic photosensitizer, can easily reach a photoexcited state that is available for both an oxidative and a reductive quenching. PMID- 30277642 TI - Hypertensive organ damage predicts future cognitive performance: A 9-year follow up study in patients with hypertension. AB - Hypertension is associated with cognitive deficits, probably caused by cerebral small vessel disease. The authors examined whether additional presence of cardiac and renal organ damages, and their combined presence, are associated with future cognitive performance. In 78 patients with essential hypertension (mean age 51.2 +/- 12.0 years), brain damage was determined by MRI features, cardiac damage by left ventricular mass index (LVMI), and renal damage by estimated glomerular filtration rate (eGFR) and albuminuria. At 9-year follow-up, neuropsychological assessment was performed. LVMI was associated with future lower cognition (P = 0.032), independent of age, sex, premorbid cognition, and brain damage, but eGFR and albuminuria were not. The presence of 2 or 3 types of organ damage compared to none was associated with future lower cognition. Increasing number of hypertensive organ damages, and cardiac damage independently of brain damage, might indicate a more severe hypertensive disease burden and could help to identify patients at risk of cognitive problems. PMID- 30277644 TI - Drug Design Concepts for LSD1-Selective Inhibitors. AB - Lysine-specific demethylase 1 (LSD1) is one of the flavin-dependent oxidases and is involved in many cellular processes by controlling the methylation of histone H3. Recently, it has been reported that LSD1 is associated with several diseases such as cancer, metabolic disorders, and psychiatric diseases. Thus, LSD1 is an attractive molecular target for the treatment of these diseases, and its inhibitors are predicted as therapeutic agents. Although a variety of LSD1 inhibitors have been reported to date, many of them show insufficient activities and selectivity toward LSD1. Meanwhile, we identified several LSD1-selective inhibitors using target-guided synthesis strategies based on our original ideas. Our LSD1 inhibitors show not only potent LSD1-selective inhibitory activities, but also unique bioactivities both in vitro and in vivo. This account highlights our drug design concepts for and identification of LSD1-selective inhibitors. PMID- 30277645 TI - Microwave Flow Chemistry as a Methodology in Organic Syntheses, Enzymatic Reactions, and Nanoparticle Syntheses. AB - Several studies have used microwaves as a heat source for carrying out various types of reactions employing circulation reaction vessels. The microwave flow chemical synthesis methodology is most appropriate in the use of microwaves in chemical syntheses. It can attenuate the problem of microwave heating (non uniform heating and penetration depth) and maximize the benefits (rapid heating and first temperature adjustments). In this brief review, we examine and explain some of the relevant features of microwave heating with applicative examples of the usage of microwave flow chemistry equipment in carrying out organic syntheses, enzymatic reactions, and (not least) nanoparticle syntheses. PMID- 30277646 TI - The Catalytic Reduction of Carboxylic Acid Derivatives and CO2 by Metal Nanoparticles on Lewis-Acidic Supports. AB - The development of heterogeneous catalysts for green chemical synthesis is currently a growing area in catalysis and sustainable chemistry. Especially the use of renewable carbon resources such as carbon dioxide (CO2 ) and biomass derived compounds (e. g. carboxylic acids, esters, and amides) represent highly attractive research targets. As these substances reside in a high oxidation state, efficient reduction processes are required in order to convert these substrates into useful and value-added chemicals. Moreover, in the interest of mass production, these substrates should be reduced by molecular H2 and a heterogeneous catalyst. In this context, our group has developed advanced catalysts and established design guidelines for catalysts that promote the reductive transformations of carboxylic acid derivatives and CO2 . Our studies show that cooperative catalysis between Lewis-acidic sites on the catalyst support and supported metal nanoparticles are crucial for the success of these challenging hydrogenations. In this review, we summarize the results of our recent studies on the direct synthesis of value-added chemicals from CO2 and carboxylic acid derivatives using supported transition-metal catalysts, and we propose a design concept for heterogeneous catalysts that promote these processes. PMID- 30277647 TI - Recent Progress in Sublimable Cationic Iridium(III) Complexes for Organic Light Emitting Diodes. AB - Sublimable cationic iridium(III) complexes consisting of light-emitting coordinated iridium(III) cations and nonluminous negative counter-ions, show excellent photophysical properties, superior electrochemical behaviors and high thermal stabilities, therefore have emerged as a new library of phosphorescent materials for various organic optoelectronic devices. Here we summarize and highlight the recent progress in sublimable cationic iridium(III) complexes, regarding the material design strategies, synthetic routes, photoluminescent characteristics in both solutions and neat films, together with the current utilization in organic light-emitting diodes based on the emissive material layers fabricated by vacuum evaporation deposition. Finally, we present a brief outlook thereon, indicating the great promise and brilliant application prospect of sublimable cationic iridium(III) complexes in future flat-panel display and solid-state lighting technology. PMID- 30277648 TI - High-production dairy cattle exhibit different rumen and fecal bacterial community and rumen metabolite profile than low-production cattle. AB - Our aim was to simultaneously investigate the gut bacteria typical characteristic and conduct rumen metabolites profiling of high production dairy cows when compared to low-production dairy cows. The bacterial differences in rumen fluid and feces were identified by 16S rDNA gene sequencing. The metabolite differences were identified by metabolomics profiling with liquid chromatography mass spectrometry (LC-MS). The results indicated that the high-production dairy cows presented a lower rumen bacterial richness and species evenness when compared to low-production dairy cows. At the phylum level, the high-production cows increased the abundance of Proteobacteria and decreased the abundance of Bacteroidetes, SR1, Verrucomicrobia, Euryarchaeota, Planctomycetes, Synergistetes, and Chloroflexi significantly (p < 0.05). At the genus level, the rumen fluid of the high-production group was significantly enriched for Butyrivibrio, Lachnospira, and Dialister (p < 0.05). Meanwhile, rumen fluid of high-production group was depleted for Prevotella, Succiniclasticum, Ruminococcu, Coprococcus,YRC22, CF231, 02d06, Anaeroplasma, Selenomonas, and Ruminobacter significantly (p < 0.05). A total of 92 discriminant metabolites were identified between high-production cows and low-production cows. Compared to rumen fluid of low-production dairy cows, 10 differential metabolites were found up-regulated in rumen fluid of high-production dairy cows, including 6alpha-Fluoropregn-4-ene 3,20-dione, 3-Octaprenyl-4-hydroxybenzoate, disopyramide, compound III(S), 1,2 Dimyristyl-sn-glycerol, 7,10,13,16-Docosatetraenoic acid, ferrous lactate, 6 Deoxyerythronolide B, vitamin D2, L-Olivosyl-oleandolide. The remaining differential metabolites were found down-regulated obviously in high-production cows. Metabolic pathway analyses indicated that most increased abundances of rumen fluid metabolites of high-yield cows were related to metabolic pathways involving biosynthesis of unsaturated fatty acids, steroid biosynthesis, ubiquinone and other terpenoid-quinone biosynthesis. Most down-regulated metabolic pathways were relevant to nucleotide metabolism, energy metabolism, lipid metabolism and biosynthesis of some antibiotics. PMID- 30277649 TI - cytometree: A binary tree algorithm for automatic gating in cytometry analysis. AB - Flow cytometry is a powerful technology that allows the high-throughput quantification of dozens of surface and intracellular proteins at the single-cell level. It has become the most widely used technology for immunophenotyping of cells over the past three decades. Due to the increasing complexity of cytometry experiments (more cells and more markers), traditional manual flow cytometry data analysis has become untenable due to its subjectivity and time-consuming nature. We present a new unsupervised algorithm called "cytometree" to perform automated population identification (aka gating) in flow cytometry. cytometree is based on the construction of a binary tree, the nodes of which are subpopulations of cells. At each node, the marker distributions are modeled by mixtures of normal distributions. Node splitting is done according to a model selection procedure based on a normalized difference of Akaike information criteria between two competing models. Post-processing of the tree structure and derived populations allows us to complete the annotation of the populations. The algorithm is shown to perform better than the state-of-the-art unsupervised algorithms previously proposed on panels introduced by the Flow Cytometry: Critical Assessment of Population Identification Methods project. The algorithm is also applied to a T cell panel proposed by the Human Immunology Project Consortium (HIPC) program; it also outperforms the best unsupervised open-source available algorithm while requiring the shortest computation time.

AB - Epoxy isonitrile containing natural products often possess specific and potent antibacterial activity against Gram-positive pathogens. This scaffold, however, is extremely labile under acidic and basic conditions, undergoing a Payne rearrangement to produce a stable epoxy ketone metabolite and releasing hydrogen cyanide. We synthesized and performed biological assays with epoxy ketone containing metabolites and identified that the epoxy isonitrile moiety is pertinent for biological activity. Serendipitously, we discovered an alpha,beta unsaturated epoxy ketone analogue that exhibited moderate activity against Staphylococcus aureus. PMID- 30277652 TI - Novel Rapid Screening of Basic Immobilized Amine Sorbent/Catalyst Water Stability by a UV/Vis/Cu2+ Technique. AB - Time-consuming thermogravimetric analysis (TGA) decomposition study is a typical practice to assess the stability of fresh and water-treated basic immobilized amine sorbents (BIAS)/catalysts. This work presents a faster and more precise spectroscopic UV/Vis/Cu2+ sorbent screening technique that quantifies aqueous amines washed from the BIAS by using UV-active amine/Cu2+ complexes. Six BIAS based catalysts, containing different amine species and a crosslinker within silica, were treated with ultrapure water and then analyzed for their CO2 capture performance and amine leach resistance/stability by using TGA (catalysts, approximately 4 h) and UV/Vis/Cu2+ techniques (wash solution, few minutes). A comparative analysis revealed that directly quantifying washed amines with UV/Vis/Cu2+ is 9-127 times more precise than indirect testing of the sorbents by TGA. Similar trends in the H2 O stability profiles of the catalysts [organic content retained values (OCR)] were reported by both analysis methods, allowing UV/Vis/Cu2+ to replace TGA for quantifying unstable leached amines. The UV/Vis/Cu2+ OCR results could be used to predict the CO2 -capture stability profile of the sorbents, confirming the reliability of this technique to rapidly screen catalyst stability and performance. PMID- 30277651 TI - Identification of LEA, a podocalyxin-like glycoprotein, as a predictor for the progression of colorectal cancer. AB - Large external antigen (LEA) is considered as a colorectal cancer (CRC) associated antigen, which was found via mAb ND-1 generated using hybridoma technology, but its molecular features remain unknown. To facilitate the clinical application of LEA, we identified LEA as a podocalyxin-like protein 1 (PODXL) with molecular weight of approximately 230 kDa, a hyperglycosylated protein, using immunoprecipitation and mass spectrometry in combination, and verified that ND-1-recognized epitope is on the terminal sialic acid of LEA. Correlation analysis between LEA and PODXL in molecular weight, immunological cross reactivity, and gene expression dependence supported the PODXL identity of the LEA. Moreover, we assessed the clinical significance of the LEA in 89 pairs of primary CRC tissues and adjacent nontumor colorectal tissues using ND-1 by quantum dot-based immunohistochemistry (QD-IHC). High LEA expression was correlated significantly with T stage (P = 0.010). Patients with high LEA expression showed significantly poorer prognosis than those with LEA low expression (P = 0.007). Multivariate analysis indicated LEA expression as an independent predictor. Furthermore, the comparative analysis showed that mAb ND-1 based IHC analysis toward sugar residue of PODXL has higher sensitivity and specificity to evaluate the LEA/PODXL expression than mAb 3D3-based method toward core protein of PODXL in CRC cell lines and clinical samples. In addition, we first found that LEA/PODXL can be secreted in exosomes from cancer cells and CRC patient peripheral blood. Our results demonstrate that LEA is an independent predictor for CRC progression and has the potential to be applied for clinical setting with high sensitivity, high specificity, and noninvasive access. PMID- 30277653 TI - Pattern of distant metastases in primary extrahepatic bile-duct cancer: A SEER based study. AB - Extrahepatic bile duct cancer (EBDC) is a combined type of malignancy mainly consisting of extrahepatic cholangiocarcinoma and gallbladder cancer. Clinically, it is featured with latent symptoms and early metastasis, leading to a poor prognosis. Therefore, this cohort study aimed to depict the possible metastatic patterns of EBDC of diverse sub-types and evaluate the prognostic significance of diverse metastatic destinations with data from the clinical database. Relevant data of total 4061 confirmed EBDC patients diagnosed between 2010 and 2013 from the Surveillance, Epidemiology and End Results (SEER) database was obtained. We applied t test to describe the baseline data of patients included and used chi square test to compare the distribution of distant metastatic sites. We further adopted odds ratio assess the combined metastatic patterns and compared survival difference of patients with different distal metastasis organ by Kaplan-Meier analysis. We identified totally 4061 patients over 18 years old diagnosed with extrahepatic bile tract malignancies between 2010 and 2013, with clear metastatic status and follow-up data, without primary malignancies. Liver and distant lymph (DL) are the two most common sites as a single metastasis organ. In combined metastasis patterns, bi-organ is more frequent than the other types. Lung is the organ preferentially for bi-organ metastasis, while bone and distant lymph similarly intend to co-metastasize with brain. Distal metastasis in EBDC patients indicates an extremely poor prognosis. According to the final analysis results, malignancies in extrahepatic bile duct exhibit similar metastatic patterns, suggesting that we can regard them as a unity to assess its development. Profound differences exist in distribution of distant extrahepatic metastatic sites and their combinations. Results from our studies would provide some information for follow-up strategies and future studies. PMID- 30277655 TI - First-in-Human Studies for a Selective RET Tyrosine Kinase Inhibitor, GSK3179106, to Investigate the Safety, Tolerability, and Pharmacokinetics in Healthy Volunteers. AB - Rearranged during transfection (RET), a neuronal growth factor receptor tyrosine kinase, regulates the development of the sympathetic, parasympathetic, motor, and sensory neurons in the enteric nervous system. GSK3179106 is a RET kinase inhibitor that was administered in double-blind, randomized, placebo-controlled single-dose and repeat-dose studies in healthy subjects to investigate its pharmacokinetics and safety/tolerability. In the single-dose study (n = 16), GSK3179106 was dosed from 10 mg to 800 mg, including a food effect arm. In the repeat-dose study (n = 46), GSK3179106 was dosed for 14 days with food once daily (QD) from 5 mg to 100 mg and twice daily (BID) at 100 mg and 200 mg. With single fasted doses, bioavailability was low and less than dose proportional. A significant food effect was observed with a 100-mg QD dose. Drug exposure after QD and BID repeat dosing with food showed dose dependency up to 100 mg but was not dose proportional. There were no significant differences in exposure between 100-mg and 200-mg BID doses of GSK3179106. Accumulation was observed with both QD and BID dosing. Single doses up to 800 mg and repeat doses up to 400 mg were well tolerated with no safety concerns in healthy subjects. PMID- 30277654 TI - Gamma-aminobutyric acid transaminase genetic polymorphism is a candidate locus for responsiveness to opioid analgesics in patients with cancer pain: An exploratory study. AB - AIM: Cancer pain impairs not only physical functions but also social functions and roles. Consequently, the overall health-related quality of life of patients with cancer pain deteriorates. Opioid analgesics are recommended for treating moderate to strong cancer pain. Advances in human genome research have fueled a growing interest to understand individual differences in responsiveness to opioid analgesics. This study aimed to explore and identify novel loci for genes predisposing an individual to opioid analgesic responsiveness. METHODS: A total of 71 cancer patients rated their pain on an 11-point numerical rating scale twice before and after increasing opioid analgesics. A genomewide association study focusing on single nucleotide polymorphisms (SNPs) was conducted to associate pain decrease with increased dosage of opioid analgesics based on weight (ie, responsiveness to opioid analgesics). A genomewide significance (P < 5E-8) was set for multiplicity of analyses to control for false positives. RESULTS: Two SNPs passed the genomewide threshold for significance. One exonic SNP (rs1641025) was located in the ABAT [4-aminobutyrate aminotransaminase (GABA transaminase)] gene on chromosome 16. The other SNP (rs12494691) was located on chromosome 3, which was not associated with any known genes. These SNPs were not associated with opioid-related adverse effects. CONCLUSIONS: Our results preliminarily suggest that both SNPs might be potential candidate loci for responsiveness to opioid analgesics, and GABA transaminase might be a possible target for developing adjuvant pharmacotherapy with opioid analgesics in adjuvant pharmacotherapy. Our results should be validated in a large-scale study with a larger sample size. PMID- 30277656 TI - Where to "cut-off"? PMID- 30277657 TI - Mind perception and moral judgment in autism. AB - Social difficulties of autistic individuals have been suggested to be caused by mind blindness, the absence of a theory of mind. Numerous studies have investigated theory of mind in autism spectrum disorder or how autistic individuals represent the mental states of others. Here, we have examined, as an alternative, mind perception, namely how individuals perceive the minds of various animate and inanimate entities. Autistic and non-autistic participants demonstrated evidence of a similar two-dimensional mind perception; agency, capacity for doing (i.e., self-control, memory, plan), and experience, capacity for feeling (i.e., fear, hunger, pain). Some targets (e.g., human infant and dog) were perceived to have low agency but high experience, while others (e.g., robot and God) were perceived to have the reverse pattern. Moreover, in both autistic and non-autistic groups, the attribution of moral blame positively correlated with agency, whereas moral consideration positively correlated with experience. These results offer new evidence of social cognition, particularly conception of mind and morality, in autism. Autism Res 2018, 11: 1239-1244. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We found that autistic and non-autistic individuals have similar thoughts regarding the minds of various living and nonliving entities. In addition, both groups gave moral consideration or blamed entities for wrongdoing according to their conception of the minds of those entities. Autistic individuals have this mind-based moral sense, which is a pivotal element with a key role in human society. PMID- 30277658 TI - The anatomy of single cell mass cytometry data. AB - Mass cytometry enables the measurement of up to 50 features on single cell. This has catalyzed a shift toward multidimensional data analysis methods, rather than the manual gating strategies as traditionally for in flow cytometry data. This shift means that data scientists are involved in the analysis process to an increasing degree. As the data is analyzed in a more unbiased fashion, where noisy or uninformative observations are not easily excluded, a deeper knowledge of the origin, noise, and modalities of the data is therefore needed to embark on useful data analysis. In this primer, we introduce the idiosyncrasies of mass cytometry data with a focus on the technical properties of how data generated with the CyTOF(r) system, and the characteristics of protein expression in the cells of the hematopoietic continuum, specifically targeted toward data scientists. We also provide a comprehensive online repository of scripts, tutorials, and example data. PMID- 30277659 TI - Temperature Difference Triggering Controlled Growth of All-Inorganic Perovskite Nanowire Arrays in Air. AB - All-inorganic perovskites have attracted increasing worldwide interest due to its significantly improved stability in atmospheric environment compared to organic inorganic hybrid perovskites, which renders it infinitely applicable in many fields such as electronics, optoelectronics, and energy storage. However, all inorganic perovskites have to confront the challenges from fabrication before their wide utilization in the aforementioned applications. Liquid-phase synthesis holds the advantage of mass production and easy modulation of composition but with the deficiencies of relatively low crystallinity and disordered products. Interestingly, gas-phase growth has complementary characteristics compared to the liquid-phase method. In this work, it is proposed that a novel temperature difference triggers growth strategy to integrate the merits of the liquid- and gas-phase methods, and the feasibility of this strategy via a simple lab-use hot plate is demonstrated. High quality all-inorganic perovskites, cesium lead halide (CsPbX3 ) nanowire arrays, can be epitaxially grown as in a gas-phase method, but at the same time, the composition of products can be easily modulated by predesigning the recipe of precursors as in the liquid-phase method on a large scale. Notably, the as-fabricated CsPbX3 perovskite nanowire arrays demonstrate excellent stability and good optoelectronic properties in air. It is believed that this novel strategy can strikingly prompt the development of perovskites fabrication and applications in future. PMID- 30277660 TI - The RareCyte(r) platform for next-generation analysis of circulating tumor cells. AB - Circulating tumor cells (CTCs) can reliably be identified in cancer patients and are associated with clinical outcome. Next-generation "liquid biopsy" technologies will expand CTC diagnostic investigation to include phenotypic characterization and single-cell molecular analysis. We describe here a rare cell analysis platform designed to comprehensively collect and identify CTCs, enable multi-parameter assessment of individual CTCs, and retrieve single cells for molecular analysis. The platform has the following four integrated components: 1) density-based separation of the CTC-containing blood fraction and sample deposition onto microscope slides; 2) automated multiparameter fluorescence staining; 3) image scanning, analysis, and review; and 4) mechanical CTC retrieval. The open platform utilizes six fluorescence channels, of which four channels are used to identify CTC and two channels are available for investigational biomarkers; a prototype assay that allows three investigational biomarker channels has been developed. Single-cell retrieval from fixed slides is compatible with whole genome amplification methods for genomic analysis. PMID- 30277661 TI - "Print-to-pattern": Silk-Based Water Lithography. AB - The requirement of nontoxic and versatile manufacturing frameworks for biologically relevant applications has imposed significant constraints on the choice of functional materials and the complementary fabrication tools. In this context, silk is actively studied, thanks to its mechanical robustness, biocompatibility, wide availability, aqueous processing conditions, and ease of functionalization. The inherent matching between the water solubility of silk and the aqueous inks of the inkjet printing (IJP) process has derived a biofriendly and versatile "print-to-pattern" scheme-termed silk-based water lithography toward scalable functional biomanufacturing. The deposition mode of IJP and the etching effect of silk film by water features a dual tone fabrication where functional molecules are dispensed additively, while the silk film is patterned in a "subtractive" fashion. Such versatility and scalability pave the way to a wide range of opportunities in the biomedical field. PMID- 30277662 TI - Combining fluorescent cell barcoding and flow cytometry-based phospho-ERK1/2 detection at short time scales in adherent cells. AB - Detection of levels of intracellular phospho-proteins is key to analyzing the dynamics of signal transduction in cellular systems. Cell-to-cell variability in the form of differences in protein level in each cell affects signaling and is implicated in prognosis of many diseases. Quantitative analysis of such variability necessitate measuring the protein levels at single-cell resolution. Single-cell intracellular protein abundance detection in statistically significant number of adherent cells for short time sampling points post stimulation using classical flow cytometry (FCM) technique has thus far been a challenge due to the detrimental effects of cell detachment methods on the cellular machinery. We systematically show that cell suspension obtained by noninvasive temperature-sensitive detachment of adherent cells is amenable to high-throughput phospho-ERK1/2 protein detection at single-cell level using FCM in these short time sampling points. We demonstrate this on three adherent cell lines, viz., HeLa, A549, and MCF7, from distinct lineages having characteristically different elasticity at 37 degrees C. In particular, we use a right combination of multiplexing via fluorescent cell barcoding (FCB) and intracellular antibody staining for simultaneous detection of phospho-ERK1/2 (pERK) stimulated by epidermal growth factor (EGF) in multiple samples. Based on systematic characterization using Alexa 350 dye, we arrive at two conditions that must be satisfied for correct implementation of FCB. Our study reveals that the temperature-sensitive detachment of HeLa cells correctly captures the expected pronounced bimodal pERK distribution as an early response to EGF, which the enzymatic treatment methods fail to detect. PMID- 30277663 TI - A shared effect of paroxetine treatment on gray matter volume in depressive patients with and without childhood maltreatment: A voxel-based morphometry study. AB - AIMS: This study assessed whether antidepressant drug treatment has a common effect on gray matter (GM) volume in MDD patients with and without childhood maltreatment (CM). METHODS: T1-weighted structural magnetic resonance imaging data were collected from 168 participants, including 51 MDD patients with CM, 31 MDD patients without CM, 48 normal controls with CM, and 38 normal controls without CM. MDD patients received 6 months of treatment with paroxetine, and 24 patients with CM, and 16 patients without CM received a second MRI scan. A whole brain voxel-based morphometry approach was used to estimate GM volume in each participant at two time points. Two-way analysis of variance (ANOVA) was used to determine the effects of MDD and CM on GM volume at baseline. Repeated measures two-way ANOVA was used to determine the treatment-by-CM interactive effect and main effect of treatment during paroxetine treatment. We further investigated the relationship between GM volume and clinical variables. RESULTS: At baseline, significant MDD-by-CM interactive effects on GM volume were mainly observed in the left parahippocampal gyrus, left entorhinal cortex, and left cuneus. GM volume was significantly lower mainly in the right middle temporal gyrus in patients with MDD than in normal controls. We did not find any significant treatment-by-CM interactive effects. However, a treatment-related increase in GM was found in the right middle temporal gyrus in both MDD groups. CONCLUSIONS: These results suggest that paroxetine treatment operates via a shared neurobiological mechanism in MDD patients with and without CM. PMID- 30277665 TI - Small-Sized Cationic miRi-PCNPs Selectively Target the Kidneys for High Efficiency Antifibrosis Treatment. AB - Small-sized cationic miRi (microRNA-21 inhibitor)-PCNPs (low molecular weight chitosan (LMWC)-modified polylactide-co-glycoside (PLGA) nanoparticles (PLNPs)) with special kidney-targeting and high-efficiency antifibrosis treatment are fabricated through coupling miRi, PLGA, and LMWC. In the miRi-PCNPs, easily degraded miRi is encapsulated in PCNPs and thus prevented from degradation by nuclease. Cytotoxicity, immunotoxicity, and systemic toxicity assays and in vitro and ex vivo fluorescence imaging suggest that PCNPs possess excellent biocompatibility, higher cellular uptake efficiency, and selective kidney targeting capacity. Western blotting, pathological staining, and real-time polymerase chain reaction analyses show that the therapeutic effect of miRi-PCNPs on kidney fibrosis is much higher than that of miRi, which is mainly through suppressing transforming growth factor beta-1/drosophila mothers against decapentaplegic protein 3 (TGF-beta1/Smad3) and extracellular signal-regulated kinases/mitogen-activated protein kinase signaling pathway by inhibiting the expression of microRNA-21. For example, the tubule damage index and tubulointerstitial fibrosis area in the miRi-PCNPs group are ~2.5-fold lower than those in the saline and bare miRi groups. The miRi-PCNPs with special kidney targeting and high-efficiency antifibrosis treatment may represent a promising strategy for designing and developing a therapeutic treatment for kidney fibrosis.

OBJECTIVES: This multi-center study aimed at a closer recognition of molecular factors linked to heterogeneity of EC by evaluating estrogen and progesterone receptors, proteins dependent on MMR genes, proteins linked to poor prognosis and metastases, and mutations in BRCA1. MATERIAL AND METHODS: Using sections of paraffin-embedded preparations, in 115 patients with EC type I and 31 with EC type II, expression of ERalpha, ERbeta1, PR, MLH1, and MSH2 proteins, as well as ARID1A, c-MET and BRCA1, was estimated by immunohistochemistry using specific antibodies. RESULTS: Expression of ERbeta1 was augmented in EC type II, in poorly differentiated cancers and with growing clinical advancement. An augmented expression of ERalpha was noted in well-differentiated EC and at lower clinical stage. An increased expression of PR and decreased of MLH1 were detected in type I EC. The expression of ARID1A and c-MET proteins showed no differences between the types of EC, stages of clinical advancement or grading. In 51.6% patients with type II EC, a loss of BRCA1 expression was disclosed; in this group of cancers a decreased expression of ERalpha was noted. CONCLUSIONS: An augmented expression of ERbeta1 was linked to type II EC. A higher expression of ERalpha in EC cancers was associated with a lower histopathological grade. A decreased expression of MLH1 protein was estimated in EC type I. Type II EC may be connected to BRCA1 mutation. PMID- 30277664 TI - Circular RNAs: Methodological challenges and perspectives in cardiovascular diseases. AB - Circular RNAs are generated by back-splicing of precursor-mRNAs. Although they have been known for many years, only recently we have started to appreciate their widespread expression and their regulatory functions in a variety of biological processes. Not surprisingly, circular RNA dysregulation and participation in the pathogenic mechanisms have started to emerge in many instances, including cardiovascular diseases. Detection, differential expression analysis and validation are the three critical points for the characterization of any RNA, and circular RNAs are no exception. Their characteristics, however, generate several problems that are yet to be completely addressed, and literature still lacks comprehensive definitions of well-defined best practices. We present a map of the current knowledge regarding circular RNAs and the critical issues limiting our understanding of their regulation and function. The goal was to provide the readers with the tools to critically decide which of the many approaches available is most suitable to their experimental plan. Although particularly focused on cardiovascular diseases, most critical issues concerning circular RNAs are common to many other fields of investigation. PMID- 30277667 TI - ALOX12 gene polymorphisms and serum selenium status in elderly osteoporotic patients. AB - BACKGROUND: Osteoporosis is a systemic bone disease which leads to a reduction in bone mass. Many studies have shown that up to 80% of bone mineral density (BMD) variations are attributed to genetic factors. Arachidonate 12-lipoxygenase enzyme, encoded by the ALOX12 gene, produces lipid peroxides as reactive oxygen species (ROS), leading to oxidative stress and the development of osteoporosis. Selenium (Se) is incorporated into selenoproteins, which may reduce the risk of osteoporosis. OBJECTIVES: We aimed to investigate the association of 2 ALOX12 single nucleotide polymorphisms (SNPs) and serum Se level with lumbar spine and femoral neck BMD among elderly individuals living in Amirkola, Iran. MATERIAL AND METHODS: The study consisted of 180 individuals aged >=60 years (90 healthy and 90 osteoporotic patients). We examined the effect of 2 ALOX12 SNPs (rs2292350 and rs9897850), using the polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) on both BMD regions measured by dual energy X-ray absorptiometry (DXA). Serum Se level was measured using an atomic absorption spectrophotometer PGG990 AAS (PG Instruments Ltd., Luterworth, USA). RESULTS: The rs2292350 SNP showed a significant association with femoral neck BMD (p = 0.04). Moreover, in terms of serum Se level, a significant difference was found between the patient group (57.58 +/-25.54 MUg/L) and the control group (81.09 +/-25.58 MUg/L) (p < 0.001). In addition, individuals with higher serum Se levels also had higher BMD of the lumbar spine (r2 = 0.392; p < 0.001) and the femoral neck (r2 = 0.478; p < 0.001). CONCLUSIONS: The results suggested that genetic variation in ALOX12 might influence BMD variations in our recruited participants. As for the patients with lower serum Se levels, it was observed that serum Se deficiency was accompanied by some ALOX12 variation, contributing to the development of osteoporosis. PMID- 30277668 TI - Clinical-pathological characteristics of patients treated for cancers of the eyelid skin and periocular areas. AB - BACKGROUND: Malignant cancers of the eyelid skin and the periocular area comprise 5-10% of facial skin malignant cancers. Basal cell carcinomas (BCCs) dominate, comprising approx. 80-90% of cancers of this area of the face. Considerably less often, in 9-14% of cases, squamous cell carcinomas (SCCs) are observed. OBJECTIVES: The aim of this study is to provide an epidemiological-clinical assessment of patients treated over the period 2006-2015 for primary malignant cancers of the eyelid skin considering histological diagnosis and clinical staging. MATERIAL AND METHODS: This study was based on an analysis of the medical records of 262 patients. Demographic data, age, sex, size and location of lesions, histological types, and clinical staging were assessed. RESULTS: In the analyzed group of 262 patients, most were over the age of 60 years. Primary cancers were most frequently located in the area of the medial canthus of the eye and in the lower eyelid skin. They were mainly lesions of 6-10 mm and 16-20 mm with histologically diagnosed basal cell carcinoma of nodular and cystic types. CONCLUSIONS: The most represented group was that of patients aged 60-70 years with primary cancers located in the medial canthus of the eye (47.3%) and in the lower eyelid. Basal cell carcinoma was diagnosed, mainly nodular and cystic types. PMID- 30277669 TI - Do CTRC mutations affect the development of alcoholic chronic pancreatitis and its course among Poles: Preliminary study. AB - BACKGROUND: Genetic mutations are one of the etiological factors that predispose people to develop chronic pancreatitis. OBJECTIVES: The aim of our study was to examine the effect of p.Trp55*, p.Arg254Trp and c.738_761del mutations in the chemotrypsin gene (CTRC) on the development of alcoholic chronic pancreatitis (ACP) in order to answer the questions whether these mutations vary between gender groups, whether they were related to the age when ACP was first diagnosed, and whether they affected the morphological changes in the pancreas and the course of ACP. MATERIAL AND METHODS: The study included 124 patients with ACP, 52 with nonalcoholic pancreatitis and 52 controls. The p.Trp55*, c.738_761del and p.Arg254Trp mutations in the CTRC gene were tested by the polymerase chain reaction (PCR). RESULTS: The c.738_761del and p.Arg254Trp mutations occurred in 3.07% and 1.31% of cases, respectively. None of the examined patients were found to have the p.Trp55* mutation. The frequency of detected mutations did not significantly differ between the study groups. The c.738_761del mutation was detected more frequently in women than in men. No significant differences were found in the age at ACP onset, morphological changes affecting the pancreas, or in the course of ACP between the patients with and without the 2 examined mutations. The c.738_761del mutation was significantly more frequent in the diabetic patients than in the non-diabetics. The patients with this mutation more frequently required surgery than those without the c.738_761del mutation. CONCLUSIONS: No relationship between the c.738_761del and p.Arg254Trp mutations and the development of APC was found. The c.738_761del mutation was more frequent in females than in males. Neither mutation affected the patient's age at ACP onset or its course. In contrast to p.Arg254Trp, the c.738_761del mutation correlated with diabetes development and the need for surgery in the course of ACP. PMID- 30277670 TI - Diseases of the oral cavity in light of the newest epigenetic research: Possible implications for stomatology. AB - Epigenetics is the study of inheritable changes in gene expression without changes in the underlying deoxyribonucleic acid (DNA) sequence. The main mechanisms of epigenetic regulation include DNA methylation, modifications in histones, and micro-ribonucleic acids (miRNA). Recent research evidence has shown that environmental and lifestyle factors dynamically interact with the genome, influencing epigenetic changes, from development to the later stages of life. This happens across a spectrum, from physiological to pathological conditions, such as genetic defects, developmental disorders, infectious or inflammatory processes, cancers, mental disorders, and substance abuse. Epigenetic studies have been conducted in various medical disciplines (e.g., oncology, internal medicine or psychiatry), adding valuable insight to standard medical approaches. However, in stomatology, epigenetic research is still in its infancy; thus, this review is aimed at presenting the role of epigenetic mechanisms in diseases of the oral cavity, including periodontal diseases, caries, developmental anomalies, and oral carcinoma. In addition, this paper reveals new insights into epigenetic biomarkers that can be helpful in the detection, early diagnosis, prognosis, and treatment of different oral diseases. Moreover, this review is focused on the possible clinical implications (diagnostic and therapeutic) of epigenetics, in the form of some noninvasive methods that can possibly be used in the future for the screening, work-up, outcome prediction and novel treatments of some dental diseases. Finally, this paper highlights that an epigenetic approach can be useful for designing novel interventions that will improve the management of oral malignancies or developmental abnormalities. PMID- 30277671 TI - The journey of the heart failure patient based on data from a single center. AB - BACKGROUND: Care for patients with heart failure (HF) in Poland requires improvement. OBJECTIVES: The aim of this study was to define the journey of a HF patient, taking into account the specialization of the hospital ward and further highly specialized outpatient care. MATERIAL AND METHODS: Using the medical system CliniNET(r) we analyzed 214 consecutive patients hospitalized due to HF (ICD-10: I50) in the period from September 1, 2015, to December 31, 2015, and also the data from post-discharge outpatient care in a 3-month period. To fairly compare the management of care and outcomes of patients hospitalized in internal medicine (IM) ward and in cardiac ward, propensity score matching was performed. The multivariate regression analysis was performed to determine the independent predictors of the hospital ward selection and risk of rehospitalization due to HF and/or death. RESULTS: The majority of patients were hospitalized due to HF for the first time (72%) and in the cardiac ward (65%). For 55% of rehospitalized patients the subsequent admission was within 3 months post-initial discharge. The independent predictors of a higher risk of rehospitalization due to HF and/or death were ischemic heart disease, atrial fibrillation (AF), chronic kidney disease (CKD), mineralocorticoid antagonism (MRA) therapy, and hospitalization in the last year (all p < 0.05). Internal medicine ward patients differed from cardiac ward patients in: mode of admission (urgent 100% vs 83.5%; p < 0.001), length of hospitalization (median 8 vs 5 days; p = 0.001), death rate (24% vs 4.3%; p < 0.001), echocardiography (43% vs 98%; p < 0.001), and NT-proBNP measurements (43% vs 96%; p < 0.001). The burden of 5-9 accompanying diseases enhanced the choice of the cardiac ward (p < 0.05), while age and urgent mode of hospitalization decreased the chance of being referred to the cardiac ward (p < 0.01). Cardiac patients were more likely to receive beta-blockers, diuretics, angiotensin receptor blockers (ARB) and MRA. Over 90% of cardiac ward patients were referred to cardiac ambulatory care after discharge from the hospital, while among patients discharged from IM ward this rate was 60% (p < 0.001). CONCLUSIONS: There were significant differences among the 2 wards in relation to the course of hospitalization and post-discharge outpatient care. PMID- 30277672 TI - Withholding and withdrawing life-sustaining treatment: Experiences in limiting futile therapy from three Polish intensive care departments. AB - BACKGROUND: In intensive care units (ICUs), a patient's vital functions may be maintained, regardless of the patient's chances of survival. A key issue is how to precisely determine the moment in which life-support treatment should be withheld. In many countries, the decision-making process is regulated by the guidelines of scientific societies. However, heuristic errors may influence this process. OBJECTIVES: The objective of this study was to assess factors involved in decisions to implement or withhold treatment in general ICUs in Poland. MATERIAL AND METHODS: The medical records of patients treated in 3 clinical ICUs of general, cardiosurgical and neurosurgical profile were retrospectively analyzed. Patients with a diagnosis of brain death were finally excluded from the study. RESULTS: The records of 1,449 patients hospitalized between January 1, 2014 and December 31, 2014 were analyzed. Of these, 226 patient cases were evaluated. There were no correlations between the placement of restrictions on resuscitation in specific cases, use of noradrenaline, frequency of blood gas testing, and patients' age. There was a relationship between these factors and the duration of hospitalization in the ICU. There was a direct relation between a "do not resuscitate" (DNR) order in a patient's record and the frequency of both resuscitation procedures and withholding catecholamine treatment in the hours preceding a patient's death. CONCLUSIONS: Treatment was withheld in about 20% of cases involving dying patients in analyzed ICUs, regardless of age. Placing a limit on treatment consisted of either withholding new procedures or withdrawing existing therapy. The length of stay in the ICU affected the decisions to limit treatment.

AB - Objective: Recent studies document posttraumatic stress disorder (PTSD) symptoms in women following at-term deliveries with health baby outcomes. However, the notion that childbirth can trigger PTSD remains controversial, and the symptom clusters are mostly unknown. The objective of this study was to examine the clustering of childbirth-induced postpartum PTSD (PP-PTSD) symptoms in comparison to DSM-5 clusters. Methods: We examined the symptom presentation of childbirth related postpartum PTSD (PP-PTSD) in a sample of 685 women. The majority of these women delivered at term. Peritraumatic stress reactions to childbirth and PP-PTSD symptoms were assessed approximately 3 months after delivery. A hierarchical cluster analysis was used to detect grouping of the PP-PTSD symptoms. Results: Childbirth-related peritraumatic stress was strongly and positively associated with PP-PTSD symptom severity. Cluster modeling revealed 4 distinguished symptom groups: reliving (some reexperiencing symptoms), namely nightmares and flashbacks; avoidance coupled with unwanted memories (other reexperiencing symptoms); negative cognitions and mood; and hyperarousal reactivity. Conclusions: Our findings show that the representation of symptoms of PTSD that develops following a stressogenic childbirth experience appears, for the most part, to resemble DSM-5 symptom clusters. More research integrating descriptive symptom assessment with biological measures is warranted to better characterize the symptom presentation of this neglected posttraumatic stress syndrome.

Health conditions are highly complex with associated social problems. The universities should train nurses with a transforming vision, by defining study plans, preventive approach and promoting health, in a context of community health. The information and communication technologies along with the nurse leadership are also essential elements of value for graduated nurses. An innovative response to social needs and transformation of society requires commitment in defining the study plans of degree and also in the master's degree and in the continuing education programs. Investigate is how to acquire the necessary skills to generate knowledge to help ensure the professional development of nurses and contribute to the persons health. PMID- 30277676 TI - [Disseminated Cryptococcosis with Eosinophilia and Elevated IgE in a Non-HIV infected Patient]. AB - In general, disseminated cryptococcosis usually occurs among immunocompromised patients, especially those with cell-mediated immunodeficiency, such as HIV infected patients. We present herein a rare case of an apparently immunocompetent 33-year-old woman who developed disseminated cryptococcal diseases, which included meningitis and pneumonia with eosinophilia, and pulmonary tuberculosis during her disease course. Pneumonia with a diffuse micronodular pattern, immediately followed by meningitis, was diagnosed as disseminated cryptococcosis, because of the presence of yeast-like-fungi demonstrated by transbronchial lung biopsy and a positive cerebrospinal fluid (CSF) culture. In addition, the pneumonia exhibited eosinophilia in the peripheral blood and bronchoalveolar lavage fluid. Re-exacerbation of the pneumonia occurred approximately 3 weeks after onset, along with a sputum culture positive for Mycobacterium tuberculosis. Administration of anti-tuberculosis drugs resulted in recovery from the pulmonary tuberculosis. The treatment of cryptococcal meningitis was initiated using a standard induction regimen;however, an unrecovered status, highlighted by elevated CSF pressure, persisted. Finally, full recovery was induced by the addition of flucytosine treatment (100 mg/kg/day) and repeated daily via lumbar puncture. The allergic condition of this patient may have contributed to the onset of disseminated cryptococcosis. PMID- 30277677 TI - [A Case Diagnosed Toxocariasis After the Intiation of Treatment with Steroids for Eosinophilic Granulomatosis with Polyangitis (EGPA)]. AB - Toxocariasis causes a variety of symptoms. We experienced a case of toxocariasis which was initially treated with steroids for Eosinophilic Granulomatosis with Polyangitis (EGPA).A 53-year-old woman with the past medical history of bronchial asthma presented at the outpatient department in the middle of August. She complained of chest discomfort lasting for one week. Ischemic heart disease was initially suspected due to ST depression on ECG and positive Troponin I. However coronary angiography did not reveal any abnormality. Her symptoms continued and after one month she presented at the hospital again with an elevated eosionophil count. Chest computed tomography showed ground glass opacities on both lungs. She was diagnosed as having EGPA based on her clinical symptoms and the results of the blood test which were consistent with the diagnostic criteria of EGPA. After prednisolone was prescribed, her symptoms and eosinophilia dramatically improved. However, we found that the histology of the lung and kidney was not compatible with EGPA and the result of serum parasite antibodies turned out to be strongly positive for toxocariasis after initiating predonisolone.Based on this result, we concluded that our patient had a case of toxocariasis and prescribed albendazole in addition to prednisolone. The patient completed a 3-week course of albendazole and a 3-month course of prednisolone without any problems. In general, steroids are not commonly used as a treatment of toxocariasis, however it seems to have been effective in this case. Toxocariasis shows a variety of symptoms and can be misdiagnosed as other diseases such as EGPA. PMID- 30277678 TI - [Introduction of a Hand-hygiene Automated Monitoring System: Accuracy in Monitoring Hand Hygiene Compliance and Its Effect in Promoting Hand Hygiene Behaviour]. AB - Hand hygiene is important in the prevention of healthcare-associated infection in hospitals, but the compliance rate of healthcare workers for hand hygiene is lower than expected. Hand hygiene compliance is usually monitored employing visual methods that are open to the Hawthorne effect and limited in terms of time and place. An automated monitoring system may provide the hand-hygiene compliance rate automatically and continuously, without suffering from the Hawthorne effect. An automated monitoring system may also improve hand hygiene by providing feedback data and real-time reminders. We report herein on an automated monitoring system that permits the tracking of hand hygiene opportunities and the disinfection compliance of healthcare workers. The aim is to establish the accuracy of the system in monitoring hand hygiene compliance and to estimate the effect of the system in promoting hand hygiene behaviour. Two studies were conducted. First, to evaluate the accuracy of hand hygiene compliance recorded by the automated monitoring system, we compared the hand hygiene compliance rate recorded by the automated monitoring system with that recorded by direct visual observation for 3 days during the same period in the same ward. For the overall period of simultaneous automated and human observations, the hand hygiene compliance rate was automatically observed to be 78% and visually observed to be 75.4%. Second, to estimate the effect of the automated monitoring system in improving health workers' compliance with hand hygiene, we installed monitoring equipment in one ward and measured the compliance rate via the automated monitoring system for 13 weeks. This study included Phase 1 with a reminder only, Phase 2 with a reminder and feedback, and Phase 3 again with a reminder only. A significant increase in hand hygiene performance was observed during phase 2, and a high rate was sustained over phase 3. In phase 1, however, there was no increase in the hand hygiene compliance rate. We found the automated monitoring system to be a useful tool for not only monitoring hand hygiene but also for improving hand hygiene compliance. PMID- 30277679 TI - [A Case of Influenza A (H1N1) pdm09 Pneumonia Occurring Out of the Influenza Season]. AB - A 42-year-old woman was referred to our hospital with a diagnosis of influenza A and pneumonia out of the influenza season. Chest CT findings resembled interstitial pneumonia, but we initiated anti viral agents and antibiotics. Flexible fiberoptic bronchoscopy was performed on hospital day 3. Based on the results of an RT-PCR analysis of broncho-alveolar lavage, this patient was diagnosed as having influenza viral pneumonia. In the influenza season, we can easily suspect influenza as a differential diagnosis, even if the patient's chest CT findings resemble interstitial pneumonia. Out of the influenza season, clinicians should take into consideration influenza viral pneumonia as a differential diagnosis. PMID- 30277680 TI - [The Effect of Intravenous Gamma-globulin Reagents on the Measurement Results of (1?3)-beta-D-glucan]. AB - Serum (1->3) beta-D-glucan (BG) measurement is a useful test for systemic mycoses, and often used. On the other hand, various factors, including administration of intravenous immunoglobulins (IVIG) may cause false-positives. In the present study, we measured BG concentration of seven IVIG preparations with three lots respectively. BG levels varied with individual IVIG preparations (<3.0 - >300 pg/mL), and contamination from manufacturing processes was suspected.With serum BG concentration of clinical specimens obtained in Niigata University Medical & Dental Hospital, the difference between before and after administration of IVIG were calculated.The false-positive rate of BG due to IVIG administration was 9.8 %, and the positive predective value was reduced to 37.5%. Above all, administration of IVIG can complicate the BG test's interpretation, and caution is required. PMID- 30277681 TI - [Investigation of the Pathophysiology and Diagnostic Methods Through a Case of Acute HIV Infection in which the Western Blot Method Remained Negative Over the Long Term and the 4th Generation Screening Assay Became Negative for a Certain Period of Time after Initiating Antiretroviral Therapy]. AB - : Confirmatory tests using Western blot (WB) and HIV-1 nucleic acid testing (HIV 1 RNA) following a positive screening test are required for the diagnosis of HIV 1 infection according to the current Japanese guidelines for HIV-1/2 diagnosis. We report herein on a rare case in a patient who remained negative for WB over 10 months in spite of being positive by fourth-generation immunoassays (4thGIA) and who subsequently seroreverted by 4thGIA for three months after initiating antiretroviral therapy. Case: A man in his early twenties previously visited a hospital because of fever in October 2012. Laboratory data revealed leukocytopenia, thrombocytopenia and increased serum ferritin, suggesting hemophagocytic syndrome (HPS). During that visit, he tested positive for a 4thGIA, but negative for HIV-1 WB and his result of HIV-1 RNA result was detected invalid because of the presence of some inhibitory material in his RNA preparation. Thereafter, he was diagnosed as having cytomegalovirus-associated HPS treatment was for which initiated. In January 2013, he developed Pneumocystis jirovecii pneumonia, and his HIV-1 RNA viral load was 7.7 * 105 copies/mL in February 2013. Acute HIV infection was suspected, because the HIV-1 WB remained negative. He was started on antiretroviral therapy in April 2013. His 4thGIA was converted to negative in May 2013 and was reconverted to positive in August 2013. HIV-1 WB, however, continued to be indeterminant until February 2014, in which it turned positive for the first time according to the CDC criteria. Methods and Results: The genetic analyses of HIV-1 were done on the gag, env, nef and pol region of the HIV-1 gene from the patient. There was no clear element to delay antibody production on the virus side. Preserved specimens of the patient were measured with eight kinds of HIV screening assay. It was thought that the fourth generation assay was positive only by the presence of the antigen until March 2013 because the antibody had not been detected. Discussion: We encountered a case of acute HIV infection in which the WB result was negative for 10 months after the first positive response of the 4thGIA. The 4thGIA is essential for the early diagnosis and early treatment of HIV infection; therefore, the 4thGIA should be strictly recommended to avoid the use of older generations of immunoassay in the diagnostic guidelines. The role of the WB test should be examined closely from various aspects for use as a confirmatory test under recent laboratory situations in which highly sensitive and specific methods, e.g. the 4th GIA, have become available. In addition, unnecessary confusion due to the diversities of antibody formation should be avoided. The antibody detection tests for HIV are still necessary and indispensable for the confirmation of the disease or the diagnosis of the acute infection stage. Therefore development of a newer antibody measuring method which could achieve an easier operation and should have a higher sensitivity and specificity for HIV confirmation is strongly expected. PMID- 30277682 TI - [The Deveroppment of Screening Methods Using the Disk Diffusion Method for Carbapenemase-producing Enterobacteriaceae]. AB - Carbapenem-resistant Enterobacteriaceae (CRE) are increasing globally. Particularly, carbapenemase-producing Enterobacteriaceae (CPE) are of concern. Rapid and accurate detection of these strains is critical for appropriate antimicrobial use and hospital infection control. In the present study, criteria for CPE screening were examined using a carbapenem susceptibility disk. Carbapenemase producers showed minimal inhibition zones for faropenem (5 MUg): 6 12 mm (mean: 6.9 mm). Some strains with the IMP-6 genotype showed inhibition zones of >30 mm for imipenem (10 MUg) and biapenem (10 MUg). All strains that formed inhibition zones for FRPM had the IMP-6 genotype. The cut off values of carbapenemase-producers, determined by ROC analysis, were 12 mm for FRPM, 24 mm for meropenem (10 MUg), 29 mm for BIPM, 25 mm for doripenem (10 MUg), 26 mm for IPM, and 24 mm for panipenem (10 MUg). Thus, the sensitivity was the highest (100%) for FRPM. Specificities were 93.44% for MEPM and DRPM and 85.25% for FRPM. Consequently, a drug sensitivity test using FRPM (5 MUg) disks facilitates simple and accurate CPE screening.

AB - A previously healthy 44-year-old male presented with fever, abdominal pain, liver dysfunction and lymphadenopathy. He was diagnosed as having acute cytomegalovirus (CMV) infection with elevated CMV-IgG and IgM, and observed with supportive therapy. He was admitted to our hospital with prolonged fever lasting for a month. Enhanced CT revealed multiple thromboses in the right pulmonary artery and superior mesenteric vein. Follow-up CT after one week revealed new-onset thromboses in the left pulmonary artery and common iliac vein. Screening tests for thrombophilia were negative. His symptoms were improved with anticoagulant therapy with intravenous heparin, followed by oral warfarin. He was discharged on admission day 28 with good condition. Follow-up CT after 6 months revealed complete resolution of the thromboses. Anticoagulant therapy was stopped after 9 months, and he has been well without recurrence. Though vascular thrombosis is a rare complication, we must be alert to the signs and symptoms of thrombosis in patients with acute CMV infection.

AB - An HIV-infected man in his 30s was transferred to our hospital after the discontinuation of antiretroviral therapy (ART) for 4 years. An intraoral tumor was identified, and a biopsy was performed. The diagnosis was Kaposi's sarcoma (KS) and disseminated lesions were detected in his respiratory tract and both lungs on computed tomography (CT) and 2-[18F] fluoro-2-deoxy-D-glucose positron emission tomography (FDG/PET) imaging with increasing standardized uptake volume (SUV: max 7.4). On the 7th day, he was intubated to maintain his airway, then antiretroviral therapy and chemotherapy with pegylated liposomal doxorubicin were immediately initiated. After a period of remission, pulmonary lesions were detected again. We regarded them as a manifestation of immune reconstitution inflammatory syndrome (IRIS) and gave him short term corticosteroids. The lesions were then successfully controlled without additional chemotherapy. This case suggests that early induction of ART and intensive care can result in the survival of patients with KS having serious stenosis of the respiratory tract. Furthermore, this presenting case suggested that the use of corticosteroids could be a candidate to control IRIS even in patients with Kaposi's sarcoma. PMID- 30277685 TI - [Mycotic Aneurysm by Saccharomyces cerevisiae-accompanying Ascending Aortic Graft Infection: A Case Report]. AB - We treated an extremely rare case of a mycotic aneurysm with infection of an artificial blood vessel by Saccharomyces cerevisiae, which was the first case in Japan. The patient was an 84-year-old woman. Five months before hospitalization, replacement of the ascending aorta was performed for a dissecting aneurysm of the ascending aorta. On regular follow-up examination, she had no symptoms, but accumulation of a liquid was detected around the artificial blood vessel on computed tomography (CT) imaging. She was immediately hospitalized. An emergency operation was performed because of the infected aneurysm, which accompanied infection of the artificial blood vessel. We could not detect any microorganisms in the blood or tissue culture, but we made a diagnosis of S. cerevisiae infection after performing broad-range polymerase chain reaction (PCR), followed by deoxyribonucleic acid (DNA) sequencing analysis.When an infected aneurysm is suspected after imaging analysis, such as CT, in a patient without fever or chest pain and with poor inflammatory reactions, an infected aneurysm caused by a fungus should be considered, even though blood or tissue culture results are negative. It is important to perform histopathological examination using Grocott silver stain and genetic testing (broad-range PCR and DNA sequencing analysis) of the tissue to identify the fungal infection.In the elderly, the number of cases of infection with S. cerevisiae may increase, and these cases may require more attention in the near future. PMID- 30277686 TI - [Medical Social Emergency Detected in Attendance by Valencia Samu]. AB - Objectives: To analyze the social emergency caused by vulnerability situations or exclusion risk discovered through the health service SAMU in the city of Valencia. Method: To do it mixed methodology has been used. For the quantitative part 195 questionnaires were collected in the eight SAMU mobile units, all of them were completed during services, descriptive and inferential statistics were used. For qualitative part semi-structured interviews were performed to SAMU and SAUS professionals. Categories and qualitative matrix was analyzed with ATLAS.tiv7. Results: From a total of 195 emergencies, 35 (17.9%) were attended on Tuesday. December was the month in which most emergencies were presented 48 (24.6%). 54.7% took place between 9 and 16 hours, of which 93 (47.7%) out of the SAUS working hours. From emergencies, 84 (50.5%) did not require transfer to hospital, compared to 83 (49.5%) than were required. SAMU units asked for social intervention in 27 (14%) cases, 24 (89%) required transfer to hospital. There was a significant (0.000), existing relationship between emergencies requiring hospital transfer by the SAMU and requiring social intervention. In interviews is demonstrated detection by the SAMU and intervention by the SAUS of social emergency. Of the qualitative results, we obtained that the SAMU across his sanitary emergencies detects social needs subject to valuation and intervention for SAUS.

AB - Nowadays, social and health representatives are putting the focus on emerging need: promote intergenerational programs and practices to generate spaces of encounter and collaboration between people of different ages. According to it, the purpose of intergenerational practices should be to achieve as aim for a society for all ages, regardless of age, an expression proposed by United Nations, not only to integrate all ages but to respond to their needs and provide them a higher quality of life. PMID- 30277696 TI - [Clinical Characteristics of Invasive Pneumococcal Disease of the Mucoid Phenotype: A Case Series]. AB - Streptococcus pneumoniae is a gram-positive coccus that causes invasive and non invasive pneumococcal diseases. Invasive pneumococcal disease (IPD) is defined as an infection confirmed by the isolation of S. pneumoniae from a normally sterile site. IPD has a high mortality rate of around 20% in adults. Colonies of S. pneumoniae show various morphological features which include a mucoid appearance. The production of large amounts of capsular polysaccharide gives colonies of S. pneumoniae their mucoid appearance. This is thought to be a mechanism of microbial escape from phagocyte killing, leading to strong pathogenicity despite their high susceptibility to antibiotics. To our knowledge, the clinical characteristics of patients with mucoid IPD are unknown. We retrospectively analyzed the records of adult patients with IPD of the mucoid phenotype at Teine Keijinkai Hospital, Hokkaido, Japan, between 2009 and 2015.Seven patients (six males) with age range between 62 and 80 years were diagnosed as having mucoid IPD during the study period. Two patients had a history of malignancy and diabetes mellitus respectively, and six patients were living independently. No patients were previously vaccinated with pneumococcal vaccine. Six patients had clinical manifestations of pneumonia; one patient had multiple concomitant complications of mastoiditis, meningitis, and prosthetic joint infection. All isolates were isolated from blood. All isolates were susceptible to beta-lactam antibiotics, while six isolates were resistant to macrolides and chloramphenicol. Based on the Quellung reaction and real-time polymerase chain reaction (PCR) results, one isolate of mucoid phenotype was confirmed as serotype 3 with the penicillin binding protein gene of pbp2x and the macrolide resistant gene of ermB. Although all patients received appropriate antibiotics based on susceptibility testing, four patients required mechanical ventilation and vasopressors. One patient had neurological sequelae (hypacusis) and two patients died during the course of hospitalization. This case series suggests that mucoid IPD can occur in immunocompetent hosts and can cause high mortality. Since most of the mucoid phenotype of S. pneumoniae are serotype 3, widespread use of pneumococcal vaccine is important to prevent morbidity and mortality associated with IPD.

AB - From April to May 2014, a total of seven cases of meropenem (MEPM)-resistant Escherichia coli were isolated from the sputum specimens in 7 different patients in a community hospital.The MICs of MEPM for isolates were 8 to 32 MUg/mL, whereas the MICs of imipenem (IPM) were 0.5 MUg/mL or 1 MUg/mL. All of the isolates possessed the metallo beta-lactamase (MBL) IMP-6 gene, and were CTX-M-2 type extended-spectrum beta-lactamase (ESBL)-producers. Pulsed-field gel electrophoresis (PFGE) patterns for the isolates were identical.At the time of specimen collection, one patient had been hospitalized for a long time and the other six patients had been comparatively recently admitted to the hospital. Of the six patients, two had been staying in the same nursing facility before admission, whereas the remaining 4 patients had no relationship with each other because they had been in separate locations. Thus, these cases were not considered to be nosocomially-acquired infection.Our findings suggest that MBL producing E. coli has been spreading widely in the community such as in local nursing facilities. PMID- 30277698 TI - [Bacteriological Analysis of Pneumococcus Detected from the Sputum of Hospitalized Children]. AB - 7-valent pneumococcal conjugate vaccine (PCV7) has been included in the routine immunization schedule since April 2013 in Japan. Serotype replacement - a phenomenon by which serotypes are replaced by non-vaccine serotypes after vaccine introduction - has been reported in invasive pneumococcal disease (IPD). Pneumococcus in sputum samples is one of the major causes of bronchopulmonary infection in children.We tried to verify whether serotype replacement of Pneumococcus occurs in sputum samples in a similar manner as in IPD.From August 2014 to September 2015, we performed antimicrobial susceptibility testing and serotyping of Streptococcus pneumoniae from sputum samples and investigated the history of PCV from hospitalized children with S. pneumoniae bronchopulmonary infection.From the results of our investigation, 80.3% of children have received PCV at least once. Serotypes of Pneumococcus were determined in 92.4% of tested strains and PCV13 strains accounted for only 9.8%. Major isolated serotypes were 15A (21.3%), 35B (19.7%), and 6C (13.1%). Those were not included in PCV13, i.e. serotype replacement occurs in bronchopulmonary infection just as in IPD. The results of antimicrobial susceptibility testing for Penicillin G indicated that penicillin-resistant S. pneumoniae (PRSP) accounted for 4.5%, penicillin intermediate resistant S. pneumoniae (PISP) accounted for 47.0% and penicillin susceptible S. pneumoniae (PSSP) accounted for 48.5%. When examining the drug susceptibility by serotypes, 15A, 19A, 23A and 35B showed a high percentage of non-susceptibility. This means there is a difference in the resistant trend by serotypes.In our study, it became clear that verifying of the serotypes of Pneumococcus in sputum is meaningful and surveillance of serotypes is important for evaluation of vaccination as IPD.

AB - The newly developed rapid diagnostic test (RDT, DK14-CA1, Denka Seiken Co., Ltd.) to detect Campylobacter antigen was evaluated using fecal specimens of patients with enteritis. The RDT is an immunochromatographic assay using colored latex and can detect Campylobacter antigen (C. jejuni and C. coli) from patients' stool samples within 15 minutes.A total of 227 stool samples obtained from patients with enteritis were examined and the results were compared with conventional culture methods. Overall sensitivity, specificity, accuracy and positive predictive value (PPV) were 75.6%, 98.6%, 89.9% and 97.0% respectively. Among 53 severe cases defined with their clinical findings, sensitivity, specificity, accuracy and PPV were 82.1%, 100%, 90.6% and 100% respectively. Mean time to obtain the result with the RDT was 7 minutes whereas the culture method took 2.2 days.This study revealed the usefulness of the newly developed RDT as a rapid detection tool for Campylobacter antigen. Although the RDT has a little lower sensitivity compared with culture method, the simple and rapid test can contribute to treatment decisions for patients with enteritis and can be used at the patient's bedside and in outpatient clinics.

AB - A 59-year-old male presented with fever, and was admitted for bacteremia due to gram-positive rod. All 5 sets of blood cultures obtained prior to the initiation of vancomycin tested positive for Bacillus subtilis. Based on the susceptibility test result, the antibiotics were changed to levofloxacin to complete a total of fourteen days treatment. The patient recovered without relapse over one year. Despite thorough examinations, the portal of entry of B. subtilis remained unclear.We retrospectively reviewed ten cases of bacteremia due to B. subtilis over 5 years in our hospital. The cases with positive B. subtilis blood cultures which were evaluated as contamination were excluded from the review. The most common portal of entry of B. subtilis was secondary bacteremia due to perforation or ileus (70%), followed by an unknown site (30%). B. subtilis should be considered not only as a contaminant but also as a true pathogen of bacteremia. PMID- 30277701 TI - [Influence of Conveen(r) Optima in the Life of a Male with Incontinence]. AB - Urinary incontinence is one of the most influential factors which negatively affect patients' quality of life suffering from spinal cord injury. It affects their self-esteem, interpersonal and work relations, their independence, together with their leisure and free time activities. Urine collectors are among the products that contribute to improve the autonomy and quality of life of patients with urinary incontinence. A simple functioning device which can be determinant in achieving that urinary incontinence has an almost nil impact in the life of a patient with spinal cord injury.

PMID- 30277702 TI - [Pneumonia and Streptococcal Toxic Shock Syndrome Due to Group A Streptococci: A Case Report]. AB - A 71-year-old woman who was undergoing immunosuppressive therapy presented with a 7-day history of productive cough and 2-day history of fever. She was diagnosed with severe pneumonia and septic shock. Meropenem, azithromycin, large amounts of fluids, and noradrenaline were administered, and high-flow nasal cannula oxygen therapy was provided. The gross appearance of the aspirated sputum was ginger like, and the gram-positive cocci in chains were identified as group A beta hemolytic streptococci (GAS), Streptococcus pyogenes. The blood sample culture test revealed negative results. Based on Stevens' criteria, the patient was finally diagnosed as having streptococcal toxic shock syndrome (STSS). Antibiotics were switched to ampicillin/sulbactam and clindamycin as an antitoxin treatment, and the patient was discharged on day 33. Serotypes of GAS were T1, M1, and emm1. Superantigens spe A, spe B, and spe F were present, and spe C was absent. These observations were compatible with the clinical features of hypotension. GAS is an uncommon cause of community-acquired pneumonia, which when potentially complicated with STSS can lead to a high mortality rate, and the rapid progression is particularly a striking feature. We should be aware that GAS can cause pneumonia, and antitoxin treatment can play a key role in STSS management.

AB - Acute retinal necrosis (ARN) is an infectious retinitis caused by varicella zoster virus (VZV), herpes simplex or cytomegalovirus. Without systemic therapy, ARN may progress bilaterally in seventy percent of unilateral patients. A 38-year old-man was admitted to our hospital with Hodgkin's lymphoma and hemophagocytic lymphohistiocytosis. During the chemotherapy, left facial herpes zoster developed. He received valacyclovir for 14 days. After improvement of the blisters, he continued acyclovir as secondary prophylaxis. Three weeks after the facial zoster, sudden visual loss in the left eye occurred. ARN induced by VZV was diagnosed with ophthalmoscopy and the polymerase chain reaction test of the anterior chamber. Because continuous chemotherapy for Hodgkin's lymphoma was needed, he continued valacyclovir as secondary prophylaxis for 6 months and he accomplished the chemotherapy without contralateral progression. Our case suggested the utility of valacyclovir for secondary prophylaxis. Further experiments would be required to establish secondary prophylaxis in immunocompromised patients.

AB - We herein report on a case of Vibrio vulnificus infection that was improved by conservative treatment in Kagoshima, Japan. A 75-year-old Japanese woman with liver cirrhosis presented to our hospital with shaking chill and right lower leg pain. Her blood culture was positive for V. vulnificus, and bullae had newly appeared on the right leg. Further history taking revealed that she had eaten some raw seafood before admission. She recovered following administration of antibiotics and small incisions in the lesion. West Japan (especially, the northern parts of Kyushu island) is well known as an endemic area of V. vulnificus infection: however, some cases had been reported in other areas in Japan. When clinicians treat cellulitis with risk factors, we should consider the possibility of V. vulnificus infection, even in a non-endemic area. Taking blood culture and early administration of appropriate antibiotics may contribute to conservative cure of some case of V. vulnificus infection.

AB - Introduction: Tele-Health or eHealth are defined as diversified health services provided remotely by a team of professionals using ICT (Information and Communication Technology) to improve the health of a user or population. Development: The development of ICT during the 2000 and 2010 decades allowed for a wider applicability of these services. Techniques like teleradiology and telepathology appeared. Tele-nursing began to be practiced through teleconsultations. Tele-nursing emerged from consulting telephone nurses in the United Kingdom and Canada. In 2005, the WHO established the Global eHealth Observatory to review the benefits of ICT. Currently in Spain, 061 Cat Salut Respon, managed by nurses, gives coverage to Catalonia through its website, telephone, email or chat. In Andalusia, Salud Responde is a service and information center providing citizens with remote healthcare. Conclusions: Health systems offer services through multichannel schemes and specific applications (apps) improving accessibility anytime, anywhere, provided with internet connection. The involvement of nurses in eHealth programs, such as telenurses, is increasingly spreading in Spain, mirroring the trend at an international level.

AB - Objective: To design an instrument to measure impairment of skin integrity in the diaper area of infants and severity of injury for the prevention and management of irritative diaper dermatitis. Methodology: Design in 3 phases: 1) comprehensive review and critical appraisal of literature to design the preliminary content of the instrument; 2) critical evaluation of initial proposal by an expert group (nursing and pediatric medicine) with opinion survey and ad hoc questions; 3) content analysis using data tabulation for the modification and final design of the instrument. Setting: Primary Care Management of Tenerife. Results: In the 1st phase a proposed instrument is designed: two groups of risk factors (10 modulators risk and 9 high risk); and a severity scale with 5 aspects to assess including 4-5 items each (depth, location, extension, type of injury, signs of infection). The 2nd phase involved 19 professionals. A Tabulation of the data grouped into add or omit factors was used. The 3rd phase ends with a modified version of the instrument: 10 modulating factors, 5 of hig risk and 4 items for each aspect to assess severity. Discussion-Conclusions: The scarce bibliography found and absence of similar tools explain the design. The next phase will be the validation of RDIC-lac instrument. Clinical Relevance: Susceptibility to prevent skin lesions in the diaper area in the pediatric age. PMID- 30277707 TI - Growing body of evidence supports intrauterine insemination as first line treatment and rejects unfounded concerns about its efficacy, risks and cost effectiveness. AB - IUI has been practiced for five decades but only three unconvincing trials attempted to demonstrate the superiority of IUI over sexual intercourse (SI). In the absence of evidence of its effectiveness, the National Institute for Clinical Excellence (NICE) recommended IVF over IUI after 2 years of unprotected SI. High quality recent data in well-constructed studies suggest that biases against IUI procedures and in favour of IVF are invalid. It is unethical to continue to misinform patients and stakeholders. The well-constructed randomised controlled trials (RCT) show IUI procedure to be efficient, with minimal risk, and above all improved cost-effectiveness when compared to IVF for live birth. IUI as first line treatment should be offered to most patients, while funding agencies and stakeholders need to be urgently informed of the cost-benefit in offering IUI. Fertility clinics, IVF interest groups, and regulatory bodies should amend their patient information and guidance to state that IUI should be the first line treatment and that IVF should be offered only when essential. Reappraising and promoting IUI based on evidence enhances patient autonomy, choices, and trust, while allowing the fertility industry to operate within an ethical and acceptable framework not seen as exploitative toward vulnerable patients.

AB - Introduction: Aiming at detecting possible causes for the lack of male nursing professionals, Bartfay et al. developed a questionnaire named Attitudes Towards Men in Nursing Scale (ATMINS), which they tested a university in Ontario, Canada. Objective: Achieve a cross-cultural adaptation and validation of the Attitudes Towards Men in Nursing Scale (ATMINS), in order to evaluate if results achieved using a Spanish sample are comparable with the Canadian study's results. Participantsm, Materials, and Method: Participants were recruited in universities of Alicante and Donostia (Basque Country). To assure voluntary participation in the study, all candidates were informed about the objective of the study and giving enough time to read the questionnaire. The questionnaire used was the Attitudes Toward Men in Nursing Scale (ATMINS), translated to Spanish. The Spanish version of the ARMINS scale was handed over to a total of 142 students from the Nursing Universities of Alicante and Donostia. Time needed to fill the questionnaires didn't exceed 5 minutes in any case, and no difficulty was observed during implementation. After testing the scale, an internal consistency analysis was performed using Cronbach's Alpha with correction by eliminating items. Validation of construct was done via Exploratory Factorial analysis with Varimax rotation. Results: The results show a reliability which does not reach a moderate degree. Eliminating item 6 in all subsamples, as well as the total sample suppressing any of the other 5 items, increases internal consistency. The exploratory factorial analysis supports a bi-factorial structure of the questionnaire with very high saturation on each factor and a negative charge inside factor 2 for item 6. The negative charge of item 6 keeps the saturation (0.717) after its inversion. By performing an internal consistency analysis taking only into account items of factor 1, the scale's consistency improves with results close to 0.70. Conclusion: The revised scale is a tool which enables easy and fast application. It is valid for the Spanish sample and provides an acceptable internal consistency. The results obtained in both universities in Spain and in Canada are comparable. PMID- 30277708 TI - [Influence of Family in the Patient with Neurological Pathology and Acute Confusional Syndrome]. AB - Summary: Given the type of pathology and age of patients in the inpatient unit of Neurology, Hospital de Cabuenes (Gijon), acute confusional syndrome (ACS) is very common in this service. Objective: To determine the influence of the family, within the limits of the hospital, in patients with neurological disease suffering from SCA. Methodology: A prospective, observational, descriptive study of 53 patients with neurological disease that suffered from SCA was performed. The study variables were: disorientation, agitation, medication, effectiveness, and body grip on each shift with and without family. All those patients suffering from any dementia or psychiatric problem before entering were discarded. Results: The mean age of the patients was 83 years old. The most common pathology was ICTUS. The patients with family were 47.4% versus 52.6% without family in three shifts. 70.3% of the patients became disoriented with family; for patients without family the percentage increased up to 83.8%. As far as nervousness is concerned, 11.4% of the patients with family experienced this behaviour in the three shifts; no-family patients suffering from nervousness were 29.4%. Medication was administered to 33% of the patients with family, and to 44% of no family patients. The effectiveness was 66.5% for patients with family and 48% for no-family patients. The use of body grip in the three shifts was 7.6% for patients with family and 64.5% for no-family patients. Conclusions: Family has a beneficial effect on neurological patients with ACS, specially by reducing the use of mechanical restraint, helping to preserve the dignity of elderly patients in an adverse environment such as a hospital.

AB - Cerumen production is a normal and protective process for the ear canal. However, cerumen should be removed when it causes symptoms (e.g., hearing loss, itching, pain, tinnitus) or prevents assessment of the external auditory canal, the tympanic membrane, or audiovestibular system. Cerumen should also be removed when it limits examination in patients who cannot communicate their symptoms, such as those with dementia or developmental delay, nonverbal patients with behavioral changes, and young children with fever, speech delay, or parental concerns. Patients with coagulopathies, hepatic failure, thrombocytopenia, or hemophilia, and those taking antiplatelet or anticoagulant medications, should be counseled about the increased risk of bleeding in the external auditory canal when cerumen is removed. Effective treatment options include cerumenolytic agents, irrigation with or without cerumenolytic pretreatment, and manual removal. Home irrigation with a bulb syringe may be appropriate for selected adults. Cotton-tipped swabs, ear candling, and olive oil drops or sprays should be avoided. If multiple attempts to remove the impacted cerumen-including a combination of treatments-are ineffective, clinicians should refer the patient to an otolaryngologist. Persistent symptoms despite resolution of the impaction should also prompt further evaluation for an alternative diagnosis. PMID- 30277728 TI - Depression: Screening and Diagnosis. AB - Depression affects an estimated 8% of persons in the United States and accounts for more than $210 billion in health care costs annually. The U.S. Preventive Services Task Force (USPSTF) and American Academy of Family Physicians recommend screening for depression in the general adult population. Additionally, the USPSTF recommends screening children and adolescents 12 to 18 years of age for major depressive disorder. All screening should be implemented with adequate systems in place to ensure accurate diagnosis, effective treatment, and appropriate follow-up. The two-item and nine-item Patient Health Questionnaires (PHQs) are commonly used validated screening tools. The PHQ-2 has sensitivity comparable with the PHQ-9 in most populations; however, the specificity of the PHQ-9 ranges from 91% to 94%, compared with 78% to 92% for the PHQ-2. If the PHQ 2 is positive for depression, the PHQ-9 or a clinical interview should be administered. Screening all postpartum women for depression is recommended by the USPSTF, American Academy of Family Physicians, American Academy of Pediatrics, and American College of Obstetricians and Gynecologists. Women should be screened for depression at least once during the perinatal period using the PHQ-2, PHQ-9, or Edinburgh Postnatal Depression Scale. In older adults, the Geriatric Depression Scale is also an appropriate screening tool for depression. If screening is positive for possible depression, the diagnosis should be confirmed using Diagnostic and Statistical Manual of Mental Disorders, 5th ed., criteria. PMID- 30277729 TI - High Blood Pressure in Children and Adolescents. AB - High blood pressure in children and adolescents is a growing health problem that is often overlooked. Children should be screened for elevated blood pressure annually beginning at three years of age or at every visit if risk factors are present. In children younger than 13 years, elevated blood pressure is defined as blood pressure in the 90th percentile or higher for age, height, and sex, and hypertension is defined as blood pressure in the 95th percentile or higher. In adolescents 13 years and older, elevated blood pressure is defined as blood pressure of 120 to 129 mm Hg systolic and less than 80 mm Hg diastolic, and hypertension is defined as blood pressure of 130/80 mm Hg or higher. Ambulatory blood pressure monitoring should be performed to confirm hypertension in children and adolescents. Primary hypertension is now the most common cause of hypertension in children and adolescents. A history and physical examination and targeted screening tests should be done to evaluate for underlying medical disorders, and children and adolescents with hypertension should be screened for comorbid cardiovascular diseases, including diabetes mellitus and hyperlipidemia. Hypertension in children is initially treated with lifestyle changes such as weight loss if overweight or obese, a healthy diet, and regular exercise. Children with symptomatic hypertension (e.g., headaches, cognitive changes), stage 2 hypertension without a modifiable factor such as obesity, evidence of left ventricular hypertrophy on echocardiography, any stage of hypertension associated with chronic kidney disease or diabetes, or persistent hypertension despite a trial of lifestyle modifications require antihypertensive medications and should be evaluated for cardiovascular damage with echocardiography. Angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, calcium channel blockers, and thiazide diuretics are effective, safe, and well-tolerated in children.

AB - Urinary retention is the acute or chronic inability to voluntarily pass an adequate amount of urine. The condition predominantly affects men. The most common causes are obstructive in nature, with benign prostatic hyperplasia accounting for 53% of cases. Infectious, inflammatory, iatrogenic, and neurologic causes can also affect urinary retention. Initial evaluation should involve a detailed history that includes information about current prescription medications and use of over-the-counter medications and herbal supplements. A focused physical examination with neurologic evaluation should be performed, and diagnostic testing should include measurement of postvoid residual (PVR) volume of urine. There is no consensus regarding a PVR-based definition for acute urinary retention; the American Urological Association recommends that chronic urinary retention be defined as PVR volume greater than 300 mL measured on two separate occasions and persisting for at least six months. Initial management of urinary retention involves assessment of urethral patency with prompt and complete bladder decompression by catheterization. Suprapubic catheters improve patient comfort and decrease bacteriuria and the need for recatheterization in the short term; silver alloy-coated and antibiotic-impregnated catheters offer clinically insignificant or no benefit. Further management is decided by determining the cause and chronicity of the urinary retention and can include initiation of alpha blockers with voiding trials. Patients with urinary retention related to an underlying neurologic cause should be monitored in conjunction with neurology and urology subspecialists.

AB - Zeolites have been recognized as one type of the most promising adsorbents for capturing volatile organic compounds (VOCs, e.g., toluene), but their performance suffers severely from water vapor under wet conditions. In this contribution, we demonstrated that the hydrophobicity of microporous zeolites can be significantly improved by coating vertically aligned LDH nanoplatelets when the contact angle is increased from 16.5-20.1 degrees to 44.4-64.2 degrees . The toluene adsorption capacity of such synthesized zeolite@LDH core@shell composites in wet conditions can thus be largely enhanced when the breakthrough time is increased from 6.4-10.8 to 20.1-27.5 min. PMID- 30277744 TI - Light-Scattering Sizing of Single Submicron Particles by High-Sensitivity Flow Cytometry. AB - Rapid and reliable size measurement of single submicron particles (100-1000 nm) is important for quality control of particulate matter, biomedical research, environmental study, and drug delivery system development. Though direct measurement of the elastically scattered light from individual submicron particles represents the simplest method for particle size measurement, the inadequate instrument sensitivity and complicated relationship between scattering intensity and particle size render it a great challenge. Combining the superior sensitivity of a laboratory-built high-sensitivity flow cytometer (HSFCM) in the side scattering (SSC) detection of single nanoparticles and the great efforts in synthesizing 38 highly monodisperse silica spheres ranging from 180 to 880 nm with small size intervals, here we report the first comprehensive comparison between the experimentally measured and Mie theory calculated intensities of light scattered by single submicron particles. Good agreements were observed for both the silica spheres and polystyrene beads at both the perpendicular and the parallel polarizations of the incident laser beam. Compared with perpendicular polarization, parallel polarization can resolve differently sized beads better due to the continuously increased scattering intensity with particle size. The predictive capability of the simple numerical model constructed in present work can be exploited to allow us to foresee scattering behavior on flow cytometers. More importantly, the linear correlation between the measured and the calculated scattering intensities enables us to develop a method that can measure the particle size of submicron particles with the precision and accuracy of Mie theory rather than a calibration curve fitted by several sparsely separated size reference standards. Comparable sizing resolution and accuracy to those of electron microscopy were demonstrated for Gram-positive bacteria Staphylococcus aureus. The as-developed method shows great potential in guiding the accurate size measurement of submicron particles. PMID- 30277745 TI - Piezo-phototronic Effect Enhanced Photodetector Based on CH3NH3PbI3 Single Crystals. AB - Piezoelectric organic-inorganic lead halide perovskites have recently attracted much attention in the field of optoelectronic devices. However, their piezoelectric properties as a possible way to modulate device performances have rarely been reported. Here, we study experimentally a photodetector based on CH3NH3PbI3(MAPbI3) single crystals, whose performance is effectively modulated via an emerging effect-the piezo-phototronic effect, which is to use the piezoelectric polarization charges to tune the optoelectronic processes at the interface. A piezoelectric coefficient of 10.81 pm/V of the CH3NH3PbI3 single crystal is obtained. Under 680 nm laser illumination with a power density of 3.641 mW/cm2 and at an external bias of 2 V, compared to the case without straining, the light current of the photodetector is enhanced by ~120% when a 43.48 kPa compressive pressure is applied. The response speed of the photocurrent is 3 and 2 times faster than the cases without applying pressure for the light-on and light-off states, respectively. This work proves that the performance of the photodetector based on MAPbI3 single crystals can be effectively enhanced by the piezo-phototronic effect, providing a good method for optimizing the performance of future perovskite-based optoelectronic devices. PMID- 30277746 TI - Substrate Profile of the Phosphotriesterase Homology Protein from Escherichia coli. AB - The phosphotriesterase homology protein (PHP) from Escherichia coli is a member of a family of proteins that is related to phosphotriestrase (PTE), a bacterial enzyme from cog1735 with unusual substrate specificity toward the hydrolysis of synthetic organic phosphates and phosphonates. PHP was cloned, purified to homogeneity, and functionally characterized. The three-dimensional structure of PHP was determined at a resolution of 1.84 A with zinc and phosphate in the active site. The protein folds as a distorted (beta/alpha)8-barrel and possesses a binuclear metal center in the active site. The catalytic function and substrate profile of PHP were investigated using a structure-guided approach that combined bioinformatics, computational docking, organic synthesis, and steady-state enzyme kinetics. PHP was found to catalyze the hydrolysis of phosphorylated glyceryl acetates. The best substrate was 1,2-diacetyl glycerol-3-phosphate with a kcat/ Km of 4.9 * 103 M-1 s-1. The presence of a phosphate group in the substrate was essential for enzymatic hydrolysis by the enzyme. It was surprising, however, to find that PHP was unable to hydrolyze any of the lactones tested as potential substrates, unlike most of the other enzymes from cog1735. PMID- 30277747 TI - Targeting Tumor Microenvironment by Bioreduction-Activated Nanoparticles for Light-Triggered Virotherapy. AB - Solid tumors characteristically display higher levels of lactate production due to anaerobic metabolism of glucose. Meanwhile, the U.S. Food and Drug Administration (FDA) has approved virotherapy for use in cancer treatment; however systemic administration remains as a particular challenge. Here we report exploitation of tumor lactate production in designing a hypoxia-responsive carrier, self-assembled from hyaluronic acid (HA) conjugated with 6-(2 nitroimidazole)hexylamine, for localized release of recombinant adeno-associated virus serotype 2 (AAV2). The carrier is loaded with lactate oxidase (LOX) and is permeable to small molecules such as the lactate that accumulates in the tumor. Subsequently, LOX oxidizes the lactate to pyruvate inside the carrier, accompanied by internal lowering of oxygen partial pressure. Bioreduction of the 2-nitroimidazole of the HA conjugated with 6-(2-nitroimidazole)hexylamine converts it into a hydrophilic moiety and electrostatically dissociates the carrier and virus. Efficacious and specific delivery was proven by transduction of a photosensitive protein (KillerRed), enabling significant limitation in tumor growth in vivo with photodynamic therapy. An approximate 2.44-fold reduction in tumor weight was achieved after a 2-week course, compared with control groups. Furthermore, conjugation of the AAV2 with iron oxide nanoparticles ("magnetized" AAV2) facilitated magnetic resonance imaging tracking of the virus in vivo. Taken together, the solid tumor microenvironment promotes bioreduction of the lactate responsive carrier, providing rapid and specific delivery of AAV2 for light triggered virotherapy via systemic administration. PMID- 30277748 TI - Method for the Detailed Characterization of Cosputtered Inorganic Luminescent Material Libraries. AB - Understanding the behavior of combinatorially developed luminescent materials requires detailed characterization methods that have been lacking thus far. We developed a device for directly surveying the luminescent properties of thin-film libraries created through combinatorial gradient sputter deposition. Step-scan recorded excitation-, emission- and luminescence decay spectra of a thin-film library were resolved and combined with EDX measurements on the same film, relating composition to luminescent properties. This technique was applied to a single-substrate gradient thin-film library of NaBr0.73I0.27 to NaBr0.09I0.91, doped with 6.5% to 16.5% Eu2+. This gradient film closely followed Vegard's law, with emission fluently shifting from 428 to 439 nm. In comparison, pure NaBr:Eu2+ showed emission at 428 nm and NaI:Eu2+ at 441 nm. Luminescence decay measurements demonstrated a great degree of concentration quenching in the gradient film. From these measurements we could conclude that an optimized phosphor would most efficiently luminesce when close to NaI:Eu2+. This gradient film confirmed that the method presented in this work allows to both study and optimize luminescent behavior in a broad range of host- and dopant systems.

AB - Although conjugation with polyethylene glycol (PEGylation) improves the pharmacokinetics of therapeutic proteins, it drastically decreases their bioactivity. Site-specific PEGylation counters the reduction in bioactivity, but developing PEGylated proteins with equivalent bioactivity to that of their unmodified counterparts remains challenging. This study aimed to generate PEGylated proteins with equivalent bioactivity to that of unmodified counterparts. Using interferon (IFN) as a model protein, a highly bioactive Lys deficient protein variant generated using our unique directed evolution methods enables the design of a site-specific di-PEGylated protein. Antiviral activity of our di-PEGylated IFN was similar to that of unmodified IFN-alpha2b. The di PEGylated IFN exhibited 3.0-fold greater antiviral activity than that of a commercial PEGylated IFN. Moreover, our di-PEGylated IFN showed higher in vitro and in vivo stability than those of unmodified IFN-alpha2b. Hence, we propose that highly bioactive Lys-deficient proteins solve the limitation of conventional PEGylation with respect to the reduction in bioactivity of PEGylated proteins. PMID- 30277750 TI - Combinatorial Thin Film Sputtering Au xAl1- x Alloys: Correlating Composition and Structure with Optical Properties. AB - The Au-Al alloy system was investigated via a combinatorial thin film sputtering method for its potential as a plasmonic material. Au xAl1- x combinatorial libraries were cosputtered from Au and Al elemental targets and the composition, phase, and dielectric function of a ~350 nm film was determined using energy dispersive spectroscopy (EDS), grazing incidence X-ray diffraction (GIXRD), and spectroscopic ellipsometry, respectively. The phase evolution and optical properties were analyzed after annealing various compositions under a vacuum. The phases present matched the expected phases based on the published Al-Au binary phase diagram at all compositions. Interestingly, the mixed phase Al-AuAl2 region showed the most optical tunability, where a maximum in the real part of the dielectric function progressively shifted to higher energy for increasing gold concentration. For almost pure AuAl2, the imaginary component is largely reduced in the visible range and is comparable to that of pure Al in the UV region. A 20 nm-thick film with composition Au0.74Al0.26 was studied using a (scanning) transmission electron microscope with an in situ laser heating system. The structures of the as-deposited and laser annealed films were determined using selected area diffraction and the bulk plasmon of AuAl2 and Al realized with electron energy loss spectroscopy. Last, the Au-rich solid solution region was investigated as a surface enhanced Raman spectroscopy (SERS) substrate using the benezenethiol (BT) molecule. Good SERS intensity was maintained up to 30% Al addition where enhancements of 105 to 107 were still observed. PMID- 30277751 TI - New in Vivo Compatible Matrix Metalloproteinase (MMP)-2 and MMP-9 Inhibitors. AB - Matrix metalloproteinases (MMPs) are emerging as pivotal fine-tuners of cell function in tissue homeostasis and in various pathologies, in particular inflammation. In vivo monitoring of the activity of specific MMPs, therefore, provides high potential for assessing disease progression and tissue function, and manipulation of MMP activity in tissues and whole organisms may further provide a mode of controlling pathological processes. We describe here the synthesis of novel fluorinated and nonfluorinated analogues of a secondary sulfonamide-based lead structure, compound 2, and test their efficacy as in vivo inhibitors and tracers of the gelatinases, MMP-2 and MMP-9. Using a murine neuroinflammatory model, we show that compound 2 is a highly effective in vivo inhibitor of both MMP-2 and MMP-9 activity with little or no adverse effects even after long-term daily oral administration. A fluorescein-labeled derivative compound 17 shows direct binding to activated gelatinases surrounding inflammatory cuffs in the neuroinflammation model and to pancreatic beta-cells in the islets of Langerhans, colocalizing with MMP-2 and MMP-9 activity as detected using in situ zymography techniques. These results demonstrate that compound 2 derivatives have potential as in vivo imaging tools and for future development for specific MMP-2 versus MMP-9 probes. Our chemical modifications mainly target the residues directed toward the S1' and S2' pockets and, thereby, provide new information on the structure-activity relationships of this inhibitor type. PMID- 30277752 TI - Self-Damaging Aerobic Reduction of Graphene Oxide by Escherichia coli: Role of GO Mediated Extracellular Superoxide Formation. AB - Microbial reduction of graphene oxide (GO) under aerobic conditions is poorly understood despite its critical role in changing GO toxicity and environmental fate. Here we show that 20 mg/L GO interacts with the membrane-bound cytochrome c of E. coli in saline, shuttling electrons from the respiratory chain to extracellular molecular oxygen. This results in the formation of superoxide anions (O2?-), which in turn reduce GO in 30 min. The critical role of superoxide was demonstrated by impeding GO reduction upon addition of superoxide dismutase, or by carrying out experiments under strictly anaerobic conditions that preclude O2?- formation. Coating GO with bovine serum albumin also stopped GO reduction, which indicates the need for direct contact between GO and the cell membrane. Cell death was observed as a consequence of GO bioreduction. Apparently, electron shuttling by GO (via membrane contact) interrupts the respiratory chain and induces oxidative stress, as indicated by a 20% decrease in electron transport activity and an increase in intracellular reactive oxygen species. This novel antimicrobial mechanism could be relevant to assess GO stability and biocompatibility, and informs potential applications for microbial control. PMID- 30277753 TI - Mechanistic Insight into the Binding Profile of DCVJ and alpha-Synuclein Fibril Revealed by Multiscale Simulations. AB - Parkinson's disease (PD) is a serious neurodegenerative disease and is characterized by abnormal alpha-synuclein (alpha-syn) accumulation in Lewy bodies (LB) and Lewy neurites (LN), which makes alpha-syn an important imaging target for PD. An imaging probe that quantifies fibrillar alpha-syn can enhance the clinical diagnosis of PD and can also be used to evaluate the efficacy of therapeutics aimed at reducing the abnormal aggregation of the alpha-syn fibril in the brain. In this paper, we study the binding profile of fibrillar alpha-syn with a fluorescent probe 4-(dicyanovinyl)julolidine (DCVJ), which is being explored for identifying alpha-syn imaging agents. A multiscale simulation workflow including molecular docking, molecular dynamics, metadynamics, and QM/MM calculations was implemented. We find that DCVJ can bind to multiple sites of alpha-syn which are located either at the surface or in the core. Free energy calculations using implicit solvent models reveal that the most favorable binding mode for DCVJ is associated with the core binding site and is further confirmed by metadyamics simulation. Besides, a dynamic binding pathway is discovered, which reveals that DCVJ binds gradually into the core of the fibril passing through several intermediate states. The conformational arrest of the dicyano vinyl group in the fibrillar environment could explain the reason behind the fibril-specific fluorescence of DCVJ. Furthermore, based on hybrid QM/MM calculations, the molecular geometry of the dicyano vinyl group is found to be environment specific which explains why DCVJ serves as a staining agent for such fibrillar-like environments. Our results could be helpful for elucidating the binding mechanism of imaging tracers with the fibrillar form of alpha-syn and explain their fibrillar-specific optical properties, a knowledge that in turn can be used to guide the design and development of compounds with higher affinity and selectivity for alpha-syn using structure-based strategies. PMID- 30277754 TI - Improving the Photostability of Semiconducting Polymer Dots Using Buffers. AB - The photostability of fluorescent probes is critical in biological imaging, especially for long-term observational analyses. Here, we describe a simple and universal method to improve the photostability of semiconducting polymer dots (Pdots) and other fluorescent probes by using buffers. Using Pdots as a model system, we found that HEPES or MES buffer can improve the photostability of Pdots by a factor of 20. Through a systematic study, we show that Pdot photobleaching is dominated by photoinduced radicals which can be quenched by the piperazine or morpholine structures of these buffers, which act as radical scavengers. For conditions where choice of buffer is limited, we designed fluorescent polymers conjugated with radical scavengers to improve Pdot photostability. We then demonstrate a practical application in which HEPES buffer is used to improve the photostability of Pdots during cell imaging. PMID- 30277755 TI - Polymer-Ligand-Based ELISA for Robust, High-Throughput, Quantitative Detection of p53 Aggregates. AB - A growing number of diseases are being linked to protein misfolding and amyloid formation. Recently, p53 was also shown to associate into amyloid aggregates, raising the question of whether cancer development is associated with protein aggregation as well. However, a lack of suitable tools has hampered the evaluation of their clinical relevance. Herein, we report an enzyme-linked immunosorbent-assay (ELISA) system based on a polyionic, high-molecular-weight ligand that specifically captures aggregated oligomers and amyloid proteins. We proved that naturally occurring tetramers of p53 are not bound, but high molecular-weight aggregates are bound and subsequently detected. For the first time, this assay allows the quantitative detection of p53 aggregates from cell lysates, which was demonstrated using 22 ovarian-cancer cell lines as well as 7 patient-derived tumor tissues. The levels of p53 aggregates within the missense mutated tissue samples varied more than 12-fold. This simple, robust method allows studying the abundance and clinical relevance of protein aggregates. This could help our understanding of the role of protein misfolding in cancer or even in predicting therapy responses to aggregation-targeting drugs. PMID- 30277756 TI - Coupled X-ray Fluorescence and X-ray Absorption Spectroscopy for Microscale Imaging and Identification of Sulfur Species within Tissues and Skeletons of Scleractinian Corals. AB - Identifying and mapping the wide range of sulfur species within complex matrices presents a challenge for understanding the distribution of these important biomolecules within environmental and biological systems. Here, we present a coupled micro X-ray fluorescence (MUXRF) and X-ray absorption near-edge structure (XANES) spectroscopy method for determining the presence of specific sulfur species in coral tissues and skeletons at high spatial resolution. By using multiple energy stacks and principal component analysis of a large spectral database, we were able to more accurately identify sulfur species components and distinguish different species and distributions of sulfur formerly unresolved by previous studies. Specifically, coral tissues were dominated by more reduced sulfur species, such as glutathione disulfide, cysteine, and sulfoxide, as well as organic sulfate as represented by chondroitin sulfate. Sulfoxide distributions were visually correlated with the presence of zooxanthellae endosymbionts. Coral skeletons were composed primarily of carbonate-associated sulfate (CAS) along with minor contributions from organic sulfate and a separate inorganic sulfate likely in the form of adsorbed sulfate. This coupled XRF-XANES approach allows for a more accurate and informative view of sulfur within biological systems in situ and holds great promise for pairing with other techniques to allow for a more encompassing understanding of elemental distributions within the environment. PMID- 30277757 TI - Characteristics of tire wear particles generated by a tire simulator under various driving conditions. AB - Physicochemical properties of pure tire wear particles (TWPs) were investigated in a laboratory. A tire simulator installed in an enclosing chamber was employed to eliminate artifacts caused by interfering particles during the generation and measurement of TWPs. TWP particulate matter (PM2.5 and PM10) was correlated with tire speed (r > 0.94) and load (r > 0.99). Their mass size distributions showed that TWP mode diameters ranged between 3 and 4 MUm (unimodal). Tire wear caused by slip events resulted in an increase in the number concentration (ca. 8.4 * 105 cm-3) of particles (mainly ultrafine particles (UFPs)) at low PM2.5 and PM10 values (1 and 2 MUg m-3, respectively). During braking events, UFPs were emitted at an early stage, with an increase in number concentration (up to 1.1 * 107 cm 3); a high mass concentration (3.6 mg m-3) was observed at a later stage via the coagulation of early emitted UFPs and condensation. On the basis of morphology and elemental composition, TWPs generally had elongated (micron-scale) and round/irregular (submicron-scale) shapes and they were classified into C/Si-rich, heavy metal-containing, S-containing, and mineral-containing particles. This study determined that TWP emissions can vary with changes in driving condition. PMID- 30277758 TI - PIVOTAL ROLE OF SNOW DEPOSITION AND MELTING DRIVING FLUXES OF POLYCYCLIC AROMATIC HYDROCARBONS AT COASTAL LIVINGSTON ISLAND (ANTARCTICA). AB - The atmosphere-land-ocean dynamics of semivolatile organic compounds in polar regions is poorly understood, also for the abundant and ubiquitous polycyclic aromatic hydrocarbons (PAHs). We report the concentrations and fluxes of PAHs in a polar coastal ecosystem (Livingston Island, Antarctica). From late spring (December 2014) to late summer (February 2015), we sampled air, snow, coastal seawater, plankton, and the fugacity in soils and snow. The concentrations of PAHs in seawater were low but increased during the austral summer. The PAH concentrations in snow were significantly higher than in coastal seawater. Soil air fugacity ratios showed a net volatilization of PAH when soils were covered with lichens, and close to air-soil equilibrium for bare soils. Concentrations in surface snow were also close to equilibrium with atmospheric PAHs. Conversely, there was a net diffusive deposition of PAHs to coastal seawater during late spring, but a net volatilization from seawater during late summer. Volatilization fluxes were correlated with seawater temperature and salinity, consistent with a key role of snow-melt to the fluxes and dissolved phase concentrations during the austral summer. The comprehensive assessment provided here shows that the fugacity amplification in snow is transferred to soils and coastal seawater supporting PAH concentrations and fluxes. PMID- 30277759 TI - Biocompatibility of Magnetic Resonance Imaging Nanoprobes Improved by Transformable Gadolinium Oxide Nanocoils. AB - To design functional nanomaterials for biomedical applications, the challenge for scientists is to gain further understanding of their unique toxicological properties. Nonspecific adhesion of proteins and endocytosis are considered to be the major biotoxic sources of imaging nanoprobes. Here, we fabricated ultrathin gadolinium oxide (Gd2O3) nanocoils with a low Young's modulus, which provides transformable properties in solution. The spatial configurational freedom of ultrathin nanocoils induces the steric repulsion to the nonspecific adsorption of proteins that, in turn, suppresses cellular uptake and thus improves their biocompatibility. The larger number of exposed surface gadolinium atoms of the ultrathin nanocoils provided enhanced T1 magnetic resonance (MR) imaging contrast with high signal activation. Such nanocontrast agents were applied to in vivo MR bioimaging to achieve prolonged circulation lifetime. The improved biocompatibility by transformable Gd2O3 nanocoils could open up a new perspective toward the design and construction of various nano-biomedicines in the future.

AB - Despite tremendous advances in enantioselective catalysis of the Diels-Alder reaction, the use of simple alpha,beta-unsaturated esters, one of the most abundant and useful class of dienophiles, is still severely limited in scope due to their low reactivity. We report here a catalytic asymmetric Diels-Alder methodology for a large variety of alpha,beta-unsaturated methyl esters and different dienes based on extremely reactive silylium imidodiphosphorimidate (IDPi) Lewis acids. Mechanistic insights from accurate domain-based local pair natural orbital coupled-cluster (DLPNO-CCSD(T)) calculations rationalize the catalyst control and stereochemical outcome. PMID- 30277761 TI - Lymph-Node-Targeted Immune Activation by Engineered Block Copolymer Amphiphiles TLR7/8 Agonist Conjugates. AB - Small molecule immuno-modulators such as agonists of Toll-like receptors (TLRs) are attractive compounds to stimulate innate immune cells toward potent antiviral and antitumor responses. However, small molecules rapidly enter the systemic circulation and cause "wasted inflammation". Hence, synthetic strategies to confine their radius of action to lymphoid tissue are of great relevance, to both enhance their efficacy and concomitantly limit toxicity. Here, we demonstrate that covalent conjugation of a small molecule TLR7/8 agonist immunomodulatory to a micelle-forming amphiphilic block copolymer greatly alters the pharmacokinetic profile, resulting in highly efficient lymphatic delivery. Moreover, we designed amphiphilic block copolymers in such a way to form thermodynamically stable micelles through pi-pi stacking between aromatic moieties, and we engineered the block copolymers to undergo an irreversible amphiphilic to hydrophilic transition in response to the acidic endosomal pH. PMID- 30277762 TI - An ESIPT Probe for the Ratiometric Imaging of Peroxynitrite Facilitated by Binding to Abeta-Aggregates. AB - A series of 3-hydroxyflavone (3-HF) ESIPT (excited-state intramolecular proton transfer) boronate-based fluorescent probes have been developed for the detection of peroxynitrite (ONOO-). The dyes are environmentally sensitive, and each probe exhibited a ratiometric response toward ONOO- in a micellar environment. The probes were used to image different aggregation states of amyloid-beta (Abeta) in the presence of ONOO-. The 3-HF-OMe probe was found to produce a ratiometric response toward ONOO- when bound to Abeta aggregates, resulting in a novel host guest ensemble, which adds insight into the development of other ESIPT-based probes for the simultaneous sensing of fibrous proteins/peptides and environmental ROS/RNS. PMID- 30277763 TI - Photochemistry of the 1,6-Dideuterio-1,3,5-hexatrienes in Solution: Efficient Terminal Bond Photoisomerization in One-Bond-Twist and Bicycle Pedal Ways. AB - The report that the central bond photoisomerization of the 1,3,5-hexatrienes (Hts) is highly inefficient has encouraged theoreticians to seek conical intersections (CIs) at geometries that can explain rapid nonradiative return to the initially excited isomer. Because they are photochemically silent, torsional relaxations about the terminal double bonds of the Hts have not been evaluated as significant radiationless decay pathways. Study of the photoisomerization of trans,trans,trans- and trans,cis,trans-1,6-dideuterio-1,3,5-hexatrienes ( ttt- and tct-Htd2) addresses this issue. Degassed cyclohexane- d12 (C6D12) and CD3CN solutions were irradiated at 254 nm in quartz NMR tubes, and the progress of the reactions was followed by 1H NMR. Photoisomerization rates based on the integration of terminal hydrogen NMR peaks are in reasonable agreement with rates obtained by fitting pure isomer NMR spectra to the phase shift and baseline corrected experimental NMR spectra. The results show that terminal bond isomerization is highly efficient, especially when one considers that central bond isomerization is much more efficient than previously reported and is mainly observed together with terminal bond isomerization. A mechanism involving terminal one-bond-twist (OBT) in competition with a bicycle pedal (BP) process accounts for all terminal and most central bond photoisomerization. OBT central bond isomerization is a minor reaction that is observed primarily in the tct to ttt direction. Most surprising is the prominent role of the BP process in central bond photoisomerization. Proposed initially to account for photoisomerization in free volume constraining media, it is observed here in the absence of medium constraints. PMID- 30277764 TI - Discerning the Redox-Dependent Electronic and Interfacial Structures in Electroactive Self-Assembled Monolayers. AB - We explore the redox-dependent electronic and structural changes of ferrocene terminated self-assembled monolayers (Fc SAMs) immersed in aqueous solution. By exploiting X-ray and ultraviolet photoelectron spectroscopy combined with an electrochemical cell (EC-XPS/UPS), we can electrochemically control the Fc SAMs and spectroscopically probe the induced changes with the ferrocene/ferrocenium (Fc/Fc+) redox center (Fe oxidation state), formation of 1:1 Fc+-ClO4- ion pairs, molecular orientation, and monolayer thickness. We further find the insignificant involvement of interfacial water in the Fc SAMs irrespective of redox state. Electrolyte dependencies could be identified with 0.1 M NaClO4 and HClO4 when probing partially oxidized Fc/Fc+ SAMs. Corroborating the occurrence of electrochemically induced oxidation, EC-UPS shows that oxidation to Fc+ is accompanied by a shift of the highest occupied molecular orbital toward higher binding energy. The oxidation to Fc+ is also met with an increase in work function ascribed to the induced negative interfacial dipole caused by the presence of Fc+-ClO4- ion pairs along with a contribution from the reorientation of the Fc+ SAMs. The reversibility of our observations is confirmed upon conversion from Fc+ back to the neutral Fc. The approach shown here is beneficial for a broad range of redox-responsive systems to aid in the elucidation of structure-function relationships.

AB - Stenotrophomonas maltophilia HS1 exhibits l-amino acid ester hydrolase (SmAEH) activity, which can synthesize dipeptides such as Ile-Trp, Val-Gly, and Trp-His from the corresponding amino acid methyl esters and amino acids. The gene encoding SmAEH was cloned and expressed in Escherichia coli and was purified and characterized. SmAEH shared 77% sequence identity with a known amino acid ester hydrolase (AEH) from Xanthomonas citri, which belongs to a class of beta-lactam antibiotic acylases. The thermal stability of SmAEH was evaluated using various mathematical models to assess its industrial potential. First-order kinetics provided the best description for the inactivation of the enzyme over a temperature range of 35-50 degrees C. Decimal reduction time ranged from 212.76 to 3.44 min, with a z value of 8.06 degrees C, and the deactivation energy was 204.1 kJ mol-1.

AB - The catalytic allylic C-H oxidation of alkenes plays an important role in the field of medicine chemistry. Recently, Tambar et al. improved this transformation via a heteroene reaction with the assistance of a Lewis acid-assisted chiral Bronsted acid (LBA) and achieved a selective allylic oxidation of inactivated cis internal alkenes to versatile oxidation products. By means of density functional theory (DFT) calculations, we provided a detailed investigation on the mechanism of the heteroene reaction and successfully located a new catalytic process, which is able to explain the experimental observations very well. Four different reactive pathways (pathways A, B, C, and D) for the LBA-catalyzed heteroene reaction have been designed. We found pathway D, which undergoes a protonation process for the activation of enophile benzenesulfonyl sulfurimide, has the lowest overall free energy barrier. Pathway E was put forward to lead to a minor enantiomer. The theoretical enantiomeric ratio calculated via their energy difference is consistent with the experimental report. For the heteroene reaction, we proposed a new reaction mechanism, which can assist in related transformations and the design of new LBA catalysts.

AB - The targeted choice of specific photocatalysts has been shown to play a critical role for the successful realization of challenging photoredox catalytic transformations. Herein, we demonstrate the successful implementation of a rational design strategy for a series of deliberate structural manipulations of cyanoarene-based, purely organic donor-acceptor photocatalysts, using 1,2,3,5 tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN) as a starting point. Systematic modifications of both the donor substituents as well as the acceptors' molecular core allowed us to identify strongly oxidizing as well as strongly reducing catalysts (e.g., for an unprecedented detriflation of unactivated naphthol triflate), which additionally offer remarkably balanced redox potentials with predictable trends. Especially halogen arene core substitutions are instrumental for our targeted alterations of the catalysts' redox properties. Based on their preeminent electrochemical and photophysical characteristics, all novel, purely organic photoredox catalysts were evaluated in three challenging, mechanistically distinct classes of benchmark reactions (either requiring balanced, highly oxidizing or strongly reducing properties) to demonstrate their enormous potential as customizable photocatalysts, that outperform and complement prevailing typical best photocatalysts. PMID- 30277768 TI - Effect of Structure on the Spin-Spin Interactions of Tethered Dicyanomethyl Diradicals. AB - Stable organic radicals with switchable spin states have attracted attention for a variety of applications, but a fundamental understanding of how radical structure effects the weak bonding interactions between organic radicals is limited. To evaluate the effect of chemical structure on the strength and nature of such spin interactions, a series of 14 tethered aryl dicyanomethyl diradicals were synthesized, and the structure and thermodynamic properties of the diradicals were investigated. These studies indicate that the nature of the dimer and the equilibrium thermodynamic parameters of the diradical-dimer equilibria are highly sensitive to the attachment point of the linker, the length of the linker, and the substituents on the radical itself. Values of the intramolecular Ka vary from as small as 5 to as high as 105 depending on these variables. An X ray crystal structure for a linked ortho-substituted diradical shows that the diradical forms an intramolecular sigma dimer in the crystalline state with an elongated C-C bond (1.637 A). Subtle changes to the radical structure influences the nature of the spin interactions, as fixing the dimethylamino substituent on the radical into a ring to make a julolidine-derived diradical leads to the weakest bonding interaction observed (Delta Gbonding = 1 kcal mol-1) and changes the spin-paired species from a sigma dimer to a diradical pimer. This work has implications for the design of stimuli-responsive materials that can reversibly switch between the dramatically different properties of closed-shell species and the unique properties of diradicals.

AB - The anti-inflammatory effect of Citrus kawachiensis peel powder was examined in a murine model of dextran sodium sulfate (DSS)-induced colitic mice. In addition to the whole powder, its ethanol extract rich in polyphenolic compounds and ethanol extraction residue rich in dietary fibers were used. The whole powder ameliorated the DSS-induced body weight loss (body weight changes on day 9, Control 108 +/- 2, DSS 91 +/- 4, DSS+whole peel powder 106 +/- 1%, p < 0.05), colon shortening (colon length, Control 5.0 +/- 0.1, DSS 3.9 +/- 0.1, DSS+whole peel powder 4.7 +/ 0.1 cm, p < 0.05), increased expression of pro-inflammatory cytokines (e.g., TNF alpha, Control 1.0 +/- 0.1, DSS 22.2 +/- 5.8, DSS+whole peel powder 4.3 +/- 1.5 arbitrary unit, p < 0.05), and decreased expression of colonic tight junctions (TJs) (e.g., occludin, Control 1.00 +/- 0.07, DSS 0.21 +/- 0.07, DSS+whole peel powder 0.70 +/- 0.06 arbitrary unit, p < 0.05). The resolution of abnormalities barring the decreased expression of zonula occludens-2, junctional adhesion molecule-A, and claudin-7 by the extraction residue was comparable to that achieved using the powder (body weight change 107 +/- 1%; colon length 4.7 +/- 0.1 cm; TNF-alpha 4.1 +/- 0.7; occludin 0.58 +/- 0.06 arbitrary unit, p < 0.05). The ethanol extract alone did not have any influence on these abnormalities (body weight change 94 +/- 2%; colon length 4.1 +/- 0.1 cm; TNF-alpha 40.5 +/- 9.0 arbitrary unit; occludin 0.18 +/- 0.02 arbitrary unit, p < 0.05). The powder and ethanol extraction residue, but not ethanol extract, increased fecal acetic acid concentration (Control 4.9 +/- 0.6, DSS 5.0 +/- 0.9, DSS+whole peel powder 8.8 +/ 1.8, DSS+ethanol extract 5.3 +/- 0.8, DSS+ethanol extraction residue 12.5 +/- 1.1 mmol/L, p < 0.05). Taken together, DFs in the ethanol extraction residue largely contributed to the peel powder-mediated reduction of TJ barrier defect and inflammation in colitic mice. PMID- 30277771 TI - Donor-Acceptor Fluorophores for Energy-Transfer-Mediated Photocatalysis. AB - Triplet-triplet energy transfer (EnT) is a fundamental activation pathway in photocatalysis. In this work, we report the mechanistic origins of the triplet excited state of carbazole-cyanobenzene donor-acceptor (D-A) fluorophores in EnT based photocatalytic reactions and demonstrate the key factors that control the accessibility of the 3LE (locally excited triplet state) and 3CT (charge-transfer triplet state) via a combined photochemical and transient absorption spectroscopic study. We found that the energy order between 1CT (charge transfer singlet state) and 3LE dictates the accessibility of 3LE/3CT for EnT, which can be effectively engineered by varying solvent polarity and D-A character to depopulate 3LE and facilitate EnT from the chemically more tunable 3CT state for photosensitization. Following the above design principle, a new D-A fluorophore with strong D-A character and weak redox potential is identified, which exhibits high efficiency for Ni(II)-catalyzed cross-coupling of carboxylic acids and aryl halides with a wide substrate scope and high selectivity. Our results not only provide key fundamental insight on the EnT mechanism of D-A fluorophores but also establish its wide utility in EnT-mediated photocatalytic reactions.

The initial thermal decomposition path of nitrobenzene triggered by molecular thermal motion is investigated using temperature-dependent anti-Stokes Raman spectra experiments and first-principles calculations to clarify the initial thermal decomposition micromechanism. The experiment shows that the symmetric nitro stretching, antisymmetric nitro stretching, and phenyl ring stretching vibration modes are active as increasing temperature below 500 K. The DFT method is used to examine the effects of the three mode vibrations on the initial decomposition of nitrobenzene by relaxed scan for each relevant change in bond lengths and bond angles to obtain the optimal reaction channel leading to initial thermal decomposition of nitrobenzene. The results demonstrate that the initial thermal decomposition is the isomerization of nitrobenzene to phenyl nitrite. The optimal reaction channel leading to the initial isomerization is the increase or decrease of angle O-N-C from the antisymmetric nitro stretching vibration, which causes the torsion of nitro group and the subsequent oxygen atom attacking carbon atom. The scanning energy barrier related to angle O-N-C is about 62.1 kcal/mol, which is very consistent with the calculated activation barrier of isomerization of nitrobenzene. This proves the reliability of our conclusions. PMID- 30277774 TI - Syntheses of Cyclopropyl Analogues of Disorazoles A1 and B1 and Their Thiazole Counterparts. AB - Modular syntheses of disorazoles A1 and B1 analogues in which the epoxide moieties of the natural products were replaced with cyclopropyl units have been achieved. Targeted as part of a structure-activity relationships study, these syntheses were successfully extended to the thiazole counterparts of these analogues. The retrosynthetically defined fragments were assembled through Yamaguchi esterification, Cu/Pd-catalyzed cross-coupling, Yamaguchi macrolactonization, and Cu-catalyzed cross-coupling as the key reactions. Further synthetic and biological investigations of such analogues are expected to lead to the discovery and development of potential payloads for antibody-drug conjugates as targeted cancer therapies.

AB - The effect of ring substitution on the kinetics of reaction of arenes, heterocycles, and alkenes with hydroxyl radical is investigated in terms of reactivity and selectivity, using laser flash photolysis (LFP) in acetonitrile solution. The LFP data indicate that charge-transfer contributions in the transition state play an important role in dictating reactivity, and there is a correlation between the experimental and calculated ionization potentials of the arenes and alkenes and their respective reactivities. The reactivity observed for arenes in acetonitrile exhibits a much greater sensitivity toward substitution on the ring than in water, and therefore aqueous data cannot be used to predict reactivity in nonaqueous environments. Nonaqueous solution data may be predictable from gas phase data, and vice versa. PMID- 30277775 TI - Planar Pentacoordinate versus Tetracoordinate Carbons in Ternary CBe4Li4 and CBe4Li42- Clusters. AB - Planar hypercoordinate carbon molecules are exotic species, for which the 18 electron counting has been considered a rule. We report herein computational evidence of perfectly planar C2 v CBe4Li4 (1) and D4 h CBe4Li42- (3) clusters. These ternary species contain 16 and 18 electrons, respectively. The dianion is highly symmetric with a planar tetracoordinate carbon (ptC), whereas the neutral features a planar pentacoordinate carbon (ppC). Thus, charge-state alters the coordination environments of a cluster. Chemical bonding analysis shows that both clusters have 2pi and 6sigma delocalization around the C center, suggesting that ppC or ptC clusters are governed by double pi/sigma aromaticity, rather than the 18-electron rule. The outer Be4Li4 ring in 1 and 3 also supports 2sigma aromaticity, collectively leading to 3-fold pi/sigma aromaticity for these ppC/ptC clusters. Structural transformation from ptC (3) to ppC (1) is discussed, in which the 16-electron quasi-ptC CBe4Li4 (2) cluster serves as an intermediate. Cluster 2 as a local minimum has severe out-of-plane distortion. Flattening of 2 leads to reorganization of Be4 ring around the C center, which offers space for the fifth atom to coordinate and facilitates ppC formation. The latter arrangement optimizes pi aromaticity and better manages intramolecular Coulomb repulsion. This work highlights the geometric factor (and unconventional electron counting) in the design of planar hypercoordinate carbons. PMID- 30277776 TI - Rotational Excitation of HD by Hydrogen Revisited. AB - The HD molecules are key species for the cooling of pristine gas at temperatures below 100 K. They are also known to be key tracers of H2 in protoplanetary disks and thus, they can be used as a measure of protoplanetary disks mass. Accurate modeling of the cooling mechanism and of HD abundance in astrophysical media requires a proper modeling for its excitation by both radiative and collisional processes. Here, we report quantum time-independent calculations of collisional rate coefficients for the rotational excitation of HD by H for temperatures ranging from 10 to 1000 K. The reactive and hydrogen exchange channels are taken into account in the scattering calculations. New exact quantum results are compared to previous calculations performed neglecting reactive and exchange channels. We found that for temperatures higher than ~300 K, the impact of these channels on the rate coefficients cannot be neglected. Such results suggest that the new HD-H collisional data have to be used for properly modeling HD cooling function and HD abundance in all the astrophysical environments where HD plays a role, e.g. in photon-dominated regions, protoplanetary disks, early Universe chemistry, and primordial star forming regions.

AB - Nanoscale zerovalent iron (NZVI) is one of the most extensively studied nanomaterials in the fields of wastewater treatment and remediation of soil and groundwater. However, rapid oxidative transformations of NZVI can result in reduced NZVI reactivity. Indeed, the surface passivation of NZVI is considered one of the most challenging aspects in successfully applying NZVI to contaminant degradation. The oxidation of NZVI can lead to the formation of FeII-bearing phases (e.g., FeIIO, FeII(OH)2, FeIIFeIII2O4) on the NZVI surface or complete oxidation to ferric (oxyhydr)oxides (e.g., FeIIIOOH). This corrosion phenomenon is dependent upon various factors including the composition of NZVI itself, the type and concentration of aqueous species, reaction time and oxic/anoxic environments. As such, the co-existence of different Fe oxidation states on NZVI surfaces may also, in some instances, provide a unique reactive microenvironment to promote the adsorption of contaminants and their subsequent transformation via redox reactions. Thus, an understanding of passivation chemistry, and its related mechanisms, is essential not only for effective NZVI application but also for accurately assessing the positive and negative effects of NZVI surface passivation. The aim of this review is to discuss the nature of the passivation processes that occur and the passivation byproducts that form in various environments. In particular, the review presents: i) the strengths and limitations of state-of-the-art techniques (e.g., electron microscopies and X-ray based spectroscopies) to identify passivation byproducts; ii) the passivation mechanisms proposed to occur in anoxic and oxic environments; and iii) the effects arising from synthesis procedures and the presence of inorganics/organics on the nature of the passivation byproducts that form. In addition, several depassivation strategies that may assist in increasing and/or maintaining the reactivity of NZVI are considered, thereby enhancing the effectiveness of NZVI in contaminant degradation.

AB - Green, stable, and wide electrochemical window deep eutectic solvents (DESs) are ideal candidates for electrochemical systems. However, despite several studies of their bulk properties, their structure and properties under electrified confinement have barely been investigated, which has hindered widespread use of these solvents in electrochemical applications. In this Letter, we explore the electrical double layer structure of 1:2 choline chloride-urea (Reline), with a particular focus on the electrosorption of the hydrogen bond donor on a graphene electrode using atomistic molecular dynamics simulations. We discovered that the interface is composed of a mixed layer of urea and counterions followed by a mixed charged clustered structure of all of the Reline components. This interfacial structuring is strongly dependent on the balance between intermolecular interactions and surface polarization. These results provide new insights into the electrical double layer structure of a new generation of electrolytes whose interfacial structure can be tuned at the molecular level. PMID- 30277779 TI - Re-entrant Cavities Enhance Resilience to the Cassie-to-Wenzel State Transition on Superhydrophobic Surfaces during Electrowetting. AB - Electrowetting-based droplet actuation has applications in digital microfluidics. Mobility of droplets on surfaces can be enhanced using structured superhydrophobic surfaces that offer inherently low adhesion to droplets in the Cassie state. However, these surfaces must be designed to prevent transition to the Wenzel state (in which droplets are immobile) at high electrowetting actuation voltages. The electrowetting behavior of cylindrical microposts and mushroom-shaped re-entrant microstructures, both of which afford excellent superhydrophobicity, is investigated and compared. A surface-energy-based model is employed to estimate the energy barrier for the Cassie-to-Wenzel transition and thus the electrowetting voltage required to initiate this transition. The mushroom structures are predicted to be more resilient to transition (i.e., transition occurs at a voltage that is up to 1.5 times higher) than microposts. Both types of microstructured surfaces are fabricated and electrowetting experiments performed to demonstrate that mushroom structures indeed inhibit the Cassie-to-Wenzel transition at voltages that induce such transition on the cylindrical microposts.

AB - Distance measurements by electron-electron double resonance (DEER) carried out on spin-labeled proteins delivered into cells provide new insights into the conformational states of proteins in their native environment. Such measurements depend on spin labels that exhibit high redox stability and high DEER sensitivity. Here we present a new Gd(III)-based spin label, BrPSPy-DO3A-Gd(III), which was derived from an earlier label, BrPSPy-DO3MA-Gd(III), by removing the methyl group from the methyl acetate pending arms. The small chemical modification led to a reduction in the zero-field splitting and to a significant increase in the phase memory time, which together culminated in a remarkable improvement of in-cell DEER sensitivity, while maintaining the high distance resolution. The excellent performance of BrPSPy-DO3A-Gd(III) in in-cell DEER measurements was demonstrated on doubly labeled ubiquitin and GB1 delivered into HeLa cells by electroporation. PMID- 30277781 TI - Digging for Missing Proteins Using Low-Molecular-Weight Protein Enrichment and a "Mirror Protease" Strategy. AB - In 2012, the Chromosome-Centric Human Proteome Project (C-HPP) launched an investigation for missing proteins (MPs) to complete the human proteome project (HPP). The majority of the MPs were distributed in low molecular weight (LMW) ranges, especially from 0-40 kDa. LMW protein identification is challenging, owing to their short length, low abundance, and hydrophobicity. Furthermore, many sequences from Trypsin digestion are unlikely to yield detectable peptides or reasonable quality of MS2 spectrum. Therefore, we focused on small MPs by combining LMW protein enrichment and a pair of complementary proteases strategy with Trypsin and LysargiNase for human testis samples. In-depth testis LMW protein profiling resulted in the identification of 4,063 proteins, of which 2,565 were LMW proteins, and 1,130 had paired of peptides generated from both of the Trypsin and LysargiNase. This provided additional mass spectral evidence for further verification of small MPs. Finally, two MPs were verified from the seven MP candidates. One of them, Q8N688 was verified with two series of continuous and complementary b/y-product ions from the paired of spectra for tryptic and LysargiNase digested peptides after the "mirror spectrum" matching. This make the confident identification of the representative peptides for the target MPs. On another hand, the two verified peptides for Q86WR6 were identified with the same strategy from the gel-separation and gel-elution sample, respectively. Although the other five MP candidates showed high quality spectra, they could not be sufficiently distinguished as PE1s, and require further verification. All MS datasets have been deposited in the ProteomeXchange with identifier PXD010093 (Username: reviewer01467@ebi.ac.uk; Password: 3UNjNWUA). PMID- 30277782 TI - Chemically Immobilized Antimicrobial Peptide on Polymer and Self-Assembled Monolayer Substrates. AB - Surfaces with chemically immobilized antimicrobial peptides have been shown to have great potential in various applications such as biosensors and antimicrobial coatings. This research investigated the chemical immobilization of a cecropin melittin hybrid antimicrobial peptide on two different surfaces, a polymer surface prepared by chemical vapor deposition (CVD) polymerization and a self assembled monolayer surface. We probed the structure of immobilized peptides using spectroscopic methods and correlated such structural information to the measured antimicrobial activity. We found that the hybrid peptide adopts an alpha helical structure after immobilization onto both surfaces. As we have shown previously for another alpha-helical peptide, MSI-78, immobilized on a SAM, we found that the alpha-helical hybrid peptide lies down when it contacts bacteria. This study shows that the antimicrobial activity of the surface-immobilized peptides on the two substrates can be well explained by the spectroscopically measured peptide structural data. In addition, it was found that the polymer based antimicrobial peptide coating is more stable. This is likely due to the fact that the SAM prepared using silane may be degraded after several days whereas the polymer prepared by CVD polymerization is more stable than the SAM, leading to a more stable antimicrobial coating. PMID- 30277783 TI - Diabatic States at Construction (DAC) through Generalized Singular Value Decomposition. AB - A procedure, called generalized diabatic-at-construction (GDAC), is presented to transform adiabatic potential energy surfaces into a diabatic representation by generalized singular value decomposition. First, we use a set of localized, valence bond-like configuration state functions, called DAC, as the basis states. Then, the adiabatic ground and relevant excited states are determined using multistate density functional theory (MSDFT). GDAC differs in the opposite direction from traditional approaches based on adiabatic-to-diabatic transformation with certain property restraints. The method is illustrated with applications to a model first-order bond dissociation reaction of CH3OCH2Cl polarized by a solvent molecule, the ground- and first-excited-state potential energy surfaces near the minimum conical intersection for the ammonia dimer photodissociation, and the multiple avoided curve crossings in the dissociation of lithium hydride. The GDAC diabatization method may be useful for defining charge-localized states in studies of electron transfer and proton-coupled electron transfer reactions in proteins. PMID- 30277784 TI - Multiplex Immuno-Liquid Chromatography-Mass Spectrometry-Parallel Reaction Monitoring (LC-MS-PRM) Quantitation of CD8A, CD4, LAG3, PD1, PD-L1, and PD-L2 in Frozen Human Tissues. AB - The immune status of tumors critically influences their responsiveness to PD1 blockades and other immune-based therapies. Programmed death ligand 1 (PD-L1) immunohistochemistry (IHC) is a clinically validated predictive biomarker of response to checkpoint-inhibitor therapy in a limited number of clinical settings but is poorly predictive in most. With emerging evidence that multiple pathways and immune-checkpoint proteins may coordinately contribute to the adaptive immune resistance, the identification and quantitation of multiple immune markers in tumor tissue could help identify the controlling pathways in a given patient, guide the selection of optimal therapy, and monitor response to treatment. We developed and validated a sensitive and robust immuno-liquid chromatography parallel reaction monitoring assay to simultaneously quantify the expression levels of six immune markers (CD8A, CD4, LAG3, PD1, PD-L1, and PD-L2) using as little as 1-2 mg of fresh frozen tissue. The lower limit of quantitation ranged from 0.07 ng/mg protein for PD1 to 1.0 ng/mg protein for CD4. The intrabatch accuracy was within -16.6% to 15.0% for all proteins at all concentrations, and the variation ranged from 0.8% to 14.7%, while interbatch accuracy was within 6.3% to 8.6%, and the variation ranged from 1.3% to 12.8%. The validated assay was then applied to quantify all six biomarkers in different tissues and was confirmed to have sufficient sensitivity (0.07-1.00 ng/mg protein) and reproducibility (variation ranged from 4.3 to 12.0%). In an analysis of 26 cervical tumors, CD8A and CD4 were detected in all tumors, followed by PD-L1 in 85%, LAG-3 in 65%, PD1 in 50%, and PD-L2 in 35%. The strongest correlations were observed between CD8A and CD4 ( r = 0.88) and CD8A and LAG-3 ( r = 0.86). PD1 was not significantly correlated with any of the other proteins tested. This method can be applied to survey the immune signatures across tumor types and tailored to incorporate additional markers as needed. PMID- 30277785 TI - To Which Extent Is Paramagnetic Solid-State NMR Able To Address Polymorphism in Complex Transition-Metal Oxides? AB - A detailed characterization of the polymorphs constituting cathode materials, both before and after cell cycling, is mandatory to develop more stable and powerful lithium batteries. In many cases, e.g., for transition metal lithium silicates, standard diffraction techniques cannot give a clear-cut response. Here we show that broadband adiabatic fast MAS NMR can give unique information in the case of model Li2(Mn,Fe)SiO4 high-capacity cathode materials. By coupling 7Li and 29Si 1D and 2D spectra, we are able to address polymorphs speciation also in the mixed Mn/Fe compositions, which is a nearly impossible task for X-rays and neutrons diffraction. We finally discuss the conditions under which this approach is useful when applied to rare nuclei such as 29Si. PMID- 30277786 TI - Observation of Near-Threshold Resonances in the Flavin Chromophore Anions Alloxazine and Lumichrome. AB - Lumichrome (LC) is the chromophore of the flavin family of photoactive biomolecules, where key biochemical activity involves interplay between redox and photophysical events. Questions remain about the relationship between the redox status of the ground and excited states and demand an improved understanding of the intrinsic photochemistry. Using anion photodissociation spectroscopy, we have measured the intrinsic electronic spectroscopy (564-220 nm) and accompanying photodegradation pathways of the deprotonated anionic form of LC. Experiments were also performed on alloxazine (AL), which is equivalent to LC minus two methyl groups. We observe a resonance state close to 3.8 eV for both anions for the first time, which we tentatively assign to dipole-bound excited states. For AL this state is sufficiently long-lived to facilitate dissociative electron attachment. Our results suggest that the presence of methyl group rotors at key positions along the molecular dipole may reduce the lifetime of the resonance state and hence provide a structural barrier to valence electron capture, and ensuing molecular dissociation. PMID- 30277787 TI - Plasmon-Driven Photocatalysis Leads to Products Known from E-beam and X-ray Induced Surface Chemistry. AB - Plasmonic metal nanostructures can concentrate incident optical fields in nanometer-sized volumes, called hot spots. This leads to enhanced optical responses of molecules in such a hot spot but also to chemical transformations, driven by plasmon-induced hot carriers. Here, we employ tip-enhanced Raman spectroscopy (TERS) to study the mechanism of these reactions in situ at the level of a single hot spot. Direct spectroscopic measurements reveal the energy distribution of hot electrons, as well as the temperature changes due to plasmonic heating. Therefore, charge-driven reactions can be distinguished from thermal reaction pathways. The products of the hot-carrier-driven reactions are strikingly similar to the ones known from X-ray or e-beam-induced surface chemistry despite the >100-fold energy difference between visible and X-ray photons. Understanding the analogies between those two scenarios implies new strategies for rational design of plasmonic photocatalytic reactions and for the elimination of photoinduced damage in plasmon-enhanced spectroscopy. PMID- 30277788 TI - Microlens Enhancement of Surface-Tethered Molecular Beacons. AB - The tethering of molecular beacon oligonucleotide detection probes to surface patterned poly(ethylene glycol) (PEG) microgels has enabled the integration of molecular beacons into a microarray format. The microgels not only localize the probes to specific surface positions but also maintain them in a waterlike environment. Here we extend the concept of microgel tethering to include dielectric microlenses. We show that streptavidin-functionalized polystyrene microspheres (3 MUm diameter) can be colocalized with molecular beacons using biotinylated PEG gels in patterns ranging from pseudocontinuous microgel pads with lateral dimensions on the order of tens of micrometers to individual microgels with lateral dimensions on the order of 400-500 nm. We use a simplex assay based on Influenza A detection to study the lensing behavior. The microspheres increase the effective numerical aperture of the collection optics, and we find that a tethered microsphere increases the peak intensity collected from hybridized beacons between 1.5 and 10 times depending on the specific pattern size and areal density of microgels. The highest signal increase occurs when a single microsphere is tethered to a single isolated microgel. The tethering is highly self-directed and occurs in the individual-microgel case only when the microgel is close to the optic axis of the microsphere. This alignment minimizes spherical aberration and maximizes coupling of emitted fluorescent intensity into the collection optics.

This activation led to the production of balanol and eight other metabolites. Gene disruption and metabolite profile analysis showed that the biosynthesis of balanol involved the convergence of independent PKS and NRPS pathways, and a biosynthetic pathway for balanol was proposed. PMID- 30277790 TI - Shaping the Nonlinear Emission Pattern of a Dielectric Nanoantenna by Integrated Holographic Gratings. AB - We demonstrate the shaping of the second-harmonic (SH) radiation pattern from a single AlGaAs nanodisk antenna using coplanar holographic gratings. The SH radiation emitted from the antenna toward the-otherwise forbidden-normal direction can be effectively redirected by suitably shifting the phase of the grating pattern in the azimuthal direction. The use of such gratings allows increasing the SH power collection efficiency by 2 orders of magnitude with respect to an isolated antenna and demonstrates the possibility of intensity tailoring for an arbitrary collection angle. Such reconstruction of the nonlinear emission from nanoscale antennas represents the first step toward the application of all-dielectric nanostructures for nonlinear holography. PMID- 30277791 TI - Origin of Internal Friction in Disordered Proteins Depends on Solvent Quality. AB - Protein dynamics often exhibit internal friction; i.e., contributions to friction that cannot solely be attributed to the viscosity of the solvent. Remarkably, even unfolded and intrinsically disordered proteins (IDPs) exhibit this behavior, despite typically being solvent-exposed. Several competing molecular mechanisms have been suggested to underlie this phenomenon, in particular dihedral relaxation and intrachain interactions. It has also recently been shown that single-molecule data reflecting internal friction in the disordered protein ACTR cannot be explained using polymer models unless this friction is dependent on protein collapse. However, the connection between the collapse of the chain and the underlying mechanism of internal friction has been unclear. To address this issue, we combine molecular simulation and single-molecule experimental data to investigate how chain compaction affects protein dynamics in the context of ACTR. Chain reconfiguration times and internal friction estimated from all-atom simulations are in semiquantitative agreement with experimental data. We dissect the underlying molecular mechanism with all-atom and coarse-grained simulations and clearly identify both intrachain interactions and dihedral angle transitions as contributions to internal friction. However, their relative contribution is strongly dependent on the compactness of the IDP; while dihedral relaxation dominates internal friction in expanded configurations, intrachain interactions dominate for more compact chains. Our results thus imply a continuous transition between mechanisms and provide a link between internal friction in IDPs and that in more compact and folded states of proteins. PMID- 30277792 TI - Regulation of Catalytic DNA Activities with Thermosensitive Gold Nanoparticle Surfaces. AB - The regulation of the activities of catalytic DNA is of great importance in many applications, especially in biosensing, controllable drug carriers, and gene therapy. In this work, the surfaces of gold nanoparticles (AuNPs) are simultaneously modified with a thermoresponsive polymer, poly( N isopropylacrylamide) (pNIPAM), and catalytic DNA to form thermosensitive catalytic DNA/pNIPAM/AuNP systems. The thermosensitive pNIPAM on the surfaces of AuNPs enables the temperature-controlled catalytic activities of the system in a narrow temperature range. The catalytic DNA/pNIPAM/AuNP system exhibits almost no catalytic activity at temperatures below the lower critical solution temperature (LCST) of pNIPAM and become highly catalytic when the temperature is higher than the LCST. Two kinds of catalytic DNA, the entropy-driven DNA catalytic network and the Mg2+-dependent DNAzyme, were chosen as model catalytic systems, and the results showed that the regulation of catalytic activities for both systems was achieved efficiently. These systems may have important potentials in future biosensing and biomedical applications. PMID- 30277793 TI - The Regulatory Effects of Brown Adipose Tissue Thermogenesis on Maternal Metabolic Adaptation, Placental Efficiency, and Fetal Growth in Mice. AB - To determine the role of UCP1-mediated thermogenesis in controlling maternal metabolic adaptation to pregnancy, energy metabolism of C57BL/6 wild-type (WT) and Ucp1 gene knockout (Ucp1-/-) mice was studied during pregnancy. With the progression of pregnancy, maternal energy expenditure rates (EERs), expression of UCP1 and core body temperature steadily declined in WT dams. Despite no significant alterations in core body temperature and weight gain during pregnancy, Ucp1-/- dams exhibited lower rates in EER decline. High-fat (HF) feeding not only robustly increased maternal UCP1 expression and core body temperature but also abolished gestation-suppressed EER in WT dams. However, HF increased EERs were significantly attenuated in Ucp1-/- dams. Significantly increased fetal body weights and fetal/placental weight ratio were detected in fetuses from Ucp1-/- dams compared with fetuses from WT dams. Markedly increased expression levels of glucose transporter 1 and amino acid transporters were also observed in placentas from Ucp1-/- dams. Furthermore, blood glucose concentrations of fetuses from Ucp1-/- dams were significantly higher than those of fetuses from WT dams, indicating that maternal UCP1 has an inhibitory effect on placental efficiency and fetal growth. Together, this study demonstrated that maternal BAT plays an important role in controlling maternal metabolic adaptation and placental nutrient transport. PMID- 30277794 TI - Intestinal in vitro cell culture models and their potential to study the effect of food components on intestinal inflammation. AB - Cell cultures are widely used in pharmaceutical, medical, food/nutrition and biological sciences. In food and nutrition science, intestinal cell culture models of human origin are attracting increasing interest but are still rarely used in investigations of the effects of bioactive food compounds on intestinal inflammation. However, such in vitro models would, among other benefits, limit the use of in vivo models and could provide new molecular data. This review is an overview of two-dimensional (2D) and three-dimensional (3D) intestinal cell culture models and their potential use in gut inflammation studies. After describing the features of healthy and inflamed intestinal barriers, we describe the main intestinal cell lines (Caco2, HT29, T84) and their use in investigations of the transport and antioxidant/anti-inflammatory potential of some bioactive food compounds. Finally, different co-culture models of gut inflammation, in association with immune cells (PBMC, THP1 and RAW 264.7 cell lines) in both 2D and 3D models are presented. 3D models called organs-on-chips or biochips are the most recent and very promising approach made possible by bioengineering and biotechnological improvements and more accurately mimic the gut microenvironment. PMID- 30277795 TI - S100A8 Protects Human Primary Alveolar Type II Cells Against Injury and Emphysema. AB - Pulmonary emphysema is characterized by alveolar wall destruction and cigarette smoking is the main factor of this disease development. S100A8 is a member of the S100 protein family with oxidative stress-related and anti-inflammatory role. The mechanisms of human alveolar type II (ATII) cell injury leading to emphysema pathophysiology are not completely understood. We wanted to determine whether S100A8 can protect ATII cells against injury induced by cigarette smoke and this disease development. We used freshly isolated ATII cells from non-smoker and smoker organ donors, as well as emphysema patients to determine S100A8 function. S100A8 protein and mRNA levels were low in individuals with this disease and correlated with its severity as determined by using lung tissue from areas with mild and severe emphysema obtained from the same patient. Its expression negatively correlated with high oxidative stress as observed by 4-HNE levels. We also detected decreased serine phosphorylation within S100A8 by PKAalpha in this disease. This correlated with increased S100A8 ubiquitination by SYVN1. Moreover, we cultured ATII cells isolated from non-smokers followed by treatment with cigarette smoke extract. We found that this exposure upregulated S100A8 expression. We also confirmed the cytoprotective role of S100A8 against cell injury using the gain- and loss-of-function approaches in vitro. S100A8 knockdown sensitized cells to apoptosis induced by cigarette smoke. In contrast, S100A8 overexpression rescued cell injury. Our results suggest that S100A8 protects ATII cells against injury and cigarette smoke-induced emphysema. Targeting S100A8 may provide a potential therapeutic strategy in this disease. PMID- 30277796 TI - Age-Specific Associations of Ozone and PM2.5 with Respiratory Emergency Department Visits in the US. AB - RATIONALE: While associations between air pollution and respiratory morbidity for adults 65 and older are well-documented in the United States, the evidence for people under 65 is less extensive. To address this gap, the Centers for Disease Control and Prevention's National Environmental Public Health Tracking Program collected respiratory emergency department (ED) data from 17 states. OBJECTIVES: Estimate age-specific acute effects of ozone and fine particulate matter (PM2.5) on respiratory ED visits. METHODS: We conducted time-series analyses in 894 counties by linking daily respiratory ED visits with estimated ozone and PM2.5 concentrations during the week before the date of the visit. Overall effect estimates were obtained using a Bayesian hierarchical model to combine county estimates for each pollutant by age group (children 0-18, adults 19-64, adults >=65, and all ages) and by outcome group (acute respiratory infection, asthma, chronic obstructive pulmonary disease, pneumonia, and all respiratory ED visits). MEASUREMENTS AND MAIN RESULTS: Rate ratios (95% credible interval) per 10 ug/m3 increase in PM2.5 and all respiratory ED visits were 1.024 (1.018, 1.029) among children, 1.008 (1.004, 1.012) among adults <65, and 1.002 (0.996, 1.007) among adults 65 and older. Per 20 ppb increase in ozone, rate ratios were 1.017 (1.011, 1.023) among children, 1.051 (1.046, 1.056) among adults <65, and 1.033 (1.026, 1.040) among adults 65 and older. Associations varied in magnitude by age group for each outcome group. CONCLUSIONS: These results address a gap in the evidence used to ensure adequate public health protection under national air pollution policies. PMID- 30277798 TI - Evaluation of the Team Workload Questionnaire (TWLQ) in a Team-Choice Task. AB - OBJECTIVE: The present study was designed to evaluate the team workload questionnaire (TWLQ) in a task that was distinct from the task used to create it. BACKGROUND: The TWLQ was created from workload ratings generated by members of athletic sports teams. Given that such teams represent only a portion of the diversity of operational teams, we aimed to assess the generalizability of the TWLQ. METHOD: The present study applied the TWLQ in a collaborative choice task (hiring decision) to determine whether the factor structure reported in the initial publication of the scale would generalize from the execution tasks it was developed from to a disparate team task focused on consensus building. RESULTS: Confirmatory factor analysis indicated that the present data ( N = 144) were a poor fit for the three-factor structure of the TWLQ. Subsequent exploratory factor analysis revealed a much more interrelated model of team workload with no clear division between the three conceptual factors described in the original validation of the TWLQ. CONCLUSION: The factor structure of the TWLQ did not generalize to the present team-choice task. APPLICATION: Given that the duties of operational teams vary, it is critical that future research examine how the conceptual structure of team workload may be altered by task type. PMID- 30277797 TI - Leukocyte Telomere Length and Clinical Outcomes of Advanced Lung Adenocarcinoma Patients with Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors Treatment. AB - Gefitinib is currently one of the mostly used epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) recommended for treating nonsmall cell lung cancer. However, drug resistance is observed among the majority of patients after initial treatment. Factors that predict treatment prognosis and drug resistance to EGFR-TKIs remain elusive. The objective of this study is to investigate whether leukocyte relative telomere length (RTL) can be used as a prognostic biomarker of EGFR-TKIs therapy. In this study, 369 patients with stage IIIB or IV lung adenocarcinoma were recruited and treated with gefitinib as first line monotherapy. Leukocyte RTL of each patient was measured using quantitative polymerase chain reaction protocol and calculated according to Cawthon's formula. Finally, we examined the association between leukocyte RTL and prognosis or drug resistance of advanced lung adenocarcinoma to gefitinib treatment. Our results indicated that compared with long RTL, short leukocyte RTL was significantly associated with poor prognosis in all patients after gefitinib treatment (overall survival [OS]: 12.9 months vs. 17.8 months, p = 1.2 * 10-4; progression-free survival: 7.8 months vs. 13.0 months, p = 0.043). In addition, statistically significant association between short leukocyte RTL and short OS still existed among the EGFR mutant patients (hazards ratio [HR] = 1.65, 95% confidence interval [CI] = 1.28-2.12; p = 0.006). Besides EGFR mutation status, short RTL also contributed to remarkably elevated risk of gefitinib primary resistance (HR = 1.50, 95% CI = 1.05-2.15, p = 0.027). Our results highlight the clinical potential of leukocyte RTL as a novel biomarker in advanced lung adenocarcinoma treated with EGFR-TKIs. PMID- 30277799 TI - Dietary intake of anthocyanins and risk of cardiovascular disease: A systematic review and meta-analysis of prospective cohort studies. AB - Accumulating evidence suggests flavonoid intake is associated with reduced risk of non-communicable diseases. We aimed to systematically determine and quantify the potential association between dietary anthocyanin intake and risk of cardiovascular diseases (CVD). A systematic literature search of studies reporting anthocyanin intake and risk of fatal or nonfatal CVD was performed using SCOPUS, MEDLINE, CINAHL and Cochrane Library. The relative risk (RR) or hazard ratio (HR) of highest category of anthocyanin foods were pooled in a random-effects meta-analysis. Subgroup analysis were conducted to determine possible sources of heterogeneity. The meta-analysis suggested intake of dietary anthocyanins and reduced risk of CHD (RR = 0.91, 95% CI: 0.83, 0.99; I2 = 12.0, Ph = 0.337) and CVD mortality (RR = 0.92, 95% CI: 0.87, 0.97; I2 = 0.0, Ph = 0.584). However, there was no relationship between the intake of these compounds and reduced risk of MI, stroke or total CVD. Subgroup analysis determined reduced risk of CHD and CVD mortality was more prominent for anthocyanidin intake, as opposed to anthocyanin or berries. Our systematic review and meta-analysis provides evidence that anthocyanins, specifically anthocyanidins, reduce the risk of CHD and CVD mortality. Further randomized controlled trials on anthocyanin intake and CVD risk factors are needed to support these findings. PMID- 30277800 TI - Consumption of sugar sweetened beverages and dietary fructose in relation to risk of gout and hyperuricemia: a systematic review and meta-analysis. AB - BACKGROUND: Findings on the association of sugar sweetened beverages (SSB) and fructose intakes with gout and hyperuricemia have been conflicting. OBJECTIVE: We aimed to perform a systematic review and meta-analysis on studies that examined the association of SSB and fructose consumption with gout and hyperuricemia in adults. METHODS: We searched PubMed, Scopus and Google Scholar up to Aug 2017 for all relevant published papers assessing SSB and fructose intakes and risk of gout and hyperuricemia. After excluding non-relevant papers, 10 studies remained in our systematic. Meta-analysis on SSB consumption and risk of gout was done on three effect sizes from cohort studies and five effect sizes from case-control studies. For risk of hyperuricemia, the meta-analysis was done on six effect sizes from cross-sectional studies. All analyses were performed on ORs or RRs. RESULTS: We found an overall significant positive association between SSB consumption and risk of gout in both cohort (summary effect size: 1.35; 95% CI: 1.18-1.55) and case-control studies (summary effect size: 1.33; 95% CI: 1.06 1.66). Meta-analysis on cross-sectional studies revealed that SSB consumption was associated with 35% greater odds of hyperuricemia (summary effect size: 1.35; 95% CI: 1.19-1.52). No evidence of between-study heterogeneity as well as publication bias was found. Although the studies on fructose intake and risk of gout and hyperuricemia were included in our systematic review, we did not perform met analysis on these studies due to insufficient number of publications. CONCLUSION: We found that SSB consumption was significantly associated with increased risk of gout and hyperuricemia in adult population. Further studies are needed to examine the association between dietary fructose intake and risk of gout and hyepruricemia. PMID- 30277801 TI - Promoter Haplotypes of the ABCB1 Gene Encoding the P-Glycoprotein Differentially Affect Its Promoter Activity by Altering Transcription Factor Binding. AB - Promoter single nucleotide polymorphisms (SNPs) of the ABCB1 gene, encoding the placental efflux transporter P-glycoprotein, can alter its expression and affect fetal exposure to therapeutics and environmental xenobiotics. SNPs are not arrayed as independent variants but as combinations forming defined haplotypes. Recently, we defined the haplotypes encompassing ABCB1 promoter SNPs and found that ABCB1 haplotypes differentially affect its promoter activity. The mechanism(s) by which ABCB1 haplotypes alter its promoter activity are not known. We hypothesize that the haplotype-dependent differences in ABCB1 promoter activity are due to haplotype-specific alterations in transcription factor (TF) binding. To test our hypothesis, we used a TF binding profile array and determined whether differences in TF binding exist across different ABCB1 haplotypes. TFs showing significant haplotype binding differences were mechanistically evaluated using small interfering RNA (siRNA) in cultured human placental cells. Our data indicate significant haplotype-dependent differences in TF binding. Our siRNA studies showed that the regulatory effects of TFs on promoter activity are also haplotype dependent. Our data provide a mechanistic explanation for the differential effects of ABCB1 haplotypes on its promoter activity and underscore the importance of evaluating genetic variants in the context of haplotypes rather than individual SNPs when investigating their effects on gene/protein expression and disease risk. PMID- 30277802 TI - Prevalence and Characterization of Atypical Enteropathogenic Escherichia coli Isolated from Retail Foods in China. AB - Atypical enteropathogenic Escherichia coli (aEPEC) is an emerging pathogen that has been implicated in outbreaks of diarrhea worldwide. The objective of this study was to investigate the occurrence of aEPEC in retail foods at markets in the People's Republic of China and to characterize the isolates for virulence genes, intimin gene ( eae) subtypes, multilocus sequence types (STs), and antimicrobial susceptibility. From May 2014 to April 2015, 1,200 food samples were collected from retail markets in China, and 41 aEPEC isolates were detected in 2.75% (33 of 1,200) of the food samples. The virulence genes tir, katP, etpD, efa/lifA, ent, nleB, and nleE were commonly detected in these isolates. Nine eae subtypes were detected in the isolates, among which theta (23 isolates) and beta1 (6 isolates) were the most prevalent. The 41 isolates were divided into 27 STs by multilocus sequence typing. ST752 and ST10 were the most prevalent. Antibiotic susceptibility testing revealed high resistance among isolates to streptomycin (87.80%), cephalothin (73.16%), ampicillin (51.22%), tetracycline (63.42%), trimethoprim-sulfamethoxazole (43.90%), and kanamycin (43.90%). Thirty isolates (73.17%) were resistant to at least three antibiotics, and 20 (53.66 %) were resistant to five or more antibiotics. Our results suggest that retail foods in markets are important sources of aEPEC. The presence of virulent and multidrug resistant aEPEC in retail foods poses a potential threat to consumers. Surveillance of aEPEC contamination and prudent use of antibiotics is strongly recommended in China. PMID- 30277803 TI - The success and the challenge of all-trans retinoic acid in the treatment of cancer. AB - All-trans retinoic acid (ATRA), an active metabolite of vitamin A, plays important roles in cell proliferation, cell differentiation, apoptosis, and embryonic development. The effects of ATRA are mediated by nuclear retinoid receptors as well as non-genomic signal pathway, such as MAPK and PKA. The great success of differentiation therapy with ATRA in acute promyelocytic leukemia (APL) not only improved the prognosis of APL but also spurred the studies of ATRA in the treatment of other tumors. Since the genetic and physiopathological simplicity of APL is not common in human malignancies, the combination of ATRA with other agents (chemotherapy, epigenetic modifiers, and arsenic trioxide, etc) had been extensively investigated in a variety of tumors. In this review, we will discuss in details about ATRA and its role in cancer treatment. PMID- 30277804 TI - Nitric Oxide Synthase 2 Induction Promotes Right Ventricular Fibrosis. AB - The ability of the right ventricle (RV) to compensate pressure overload is determining survival in pulmonary arterial hypertension (PAH). Nitric oxide (NO) reduces the RV afterload through pulmonary vasodilation, but excessive NO amounts cause oxidative stress. Oxidative stress drives remodeling of pulmonary arteries and the RV. Here, we hypothesized that NO synthase 2 (NOS2) induction leads to excessive NO amounts that contribute to oxidative stress and impairs RV adaption to PAH. We utilized a surgical pulmonary artery banding (PAB) mouse model where RV dysfunction and remodeling occur independent from changes in the pulmonary vasculature. Three weeks after PAB, NOS2 expression was increased 2-fold in the hypertrophied RV on transcript and protein level together with increased NO production. Histomorphology localized NOS2 in interstitial and perivascular cardiac fibroblasts (CFs) after PAB, confirmed by cell isolation experiments. In the hypertrophied RV, NOS2 induction was accompanied by an increased formation of reactive oxidants - blocked by ex vivo NOS inhibition. We show that reactive oxidant formation in the hypertrophied RV is in part NOS2-dependent (in NOS2 deficient mice (NOS2-/-)). Lack of NOS2 induction prevented superoxide scavenging and decreased reactive oxidant formation. Functional measures of cardiac function by non-invasive echocardiography along with intra-cardiac catheterization revealed no differences in heart function between both genotypes after PAB. However, reduced NO and reactive oxidant formation in the hypertrophied RV of NOS2-/- mice was linked to reduced collagen accumulation through reduced collagen deposition from the cardiac fibroblast. Together, our data demonstrate a pro fibrotic role for NOS2 induction in the hypertrophied RV. PMID- 30277805 TI - Utilization of Chemical Deposition Technique for Preparation of Miniature 170Tm Sources and Preliminary Quality Assessment for Potential Use in Brachytherapy. AB - OBJECTIVE: This article describes the preparation of a 170Tm source by chemical deposition technique, its encapsulation in a titanium holder, and preliminary quality evaluation for potential utility as a brachytherapy source. METHODS: The procedure consisted of electrodeposition of Ni on a Cu wire followed by chemical deposition of 170Tm on it. Influence of feed solution pH, carrier Tm concentration, and reaction time were studied for optimum deposition of 170Tm on substrate. After sealing the source core in a titanium capsule, quality control tests were performed. Distribution of 170Tm on substrate was evaluated by autoradiography. Inactive Tm source was characterized by scanning electron microscope (SEM) and energy-dispersive X-ray (EDS) analyses. RESULTS: Under optimized conditions (pH 5, 10 MUg Tm carrier, 5 h), 170Tm source core could be prepared by deposition of >95% of 170Tm radioactivity on substrate. Swipe tests and immersion tests on encapsulated sources confirmed that removable radioactivity and radioactivity leakage levels were within stipulated limits. Autoradiography of 170Tm source confirmed uniformity of radioactivity distribution. While SEM analysis confirmed good adhesion of Tm on substrate, EDS analysis confirmed elemental constituents of the Tm-deposited substrate. CONCLUSION: The objective of preparing a 170Tm source by chemical deposition for potential brachytherapy applications could be successfully achieved. PMID- 30277806 TI - Understanding the biosyntheses and stress response mechanisms of aroma compounds in tea (Camellia sinensis) to safely and effectively improve tea aroma. AB - Metabolite formation is a biochemical and physiological feature of plants developed as an environmental response during the evolutionary process. These metabolites help defend plants against environmental stresses, but are also important quality components in crops. Utilizing the stress response to improve natural quality components in plants has attracted increasing research interest. Tea, which is processed by the tender shoots or leaves of tea plant (Camellia sinensis (L.) O. Kuntze), is the second most popular beverage worldwide after water. Aroma is an important factor affecting tea character and quality. The defense responses of tea leaves against various stresses during preharvest (tea growth process) and postharvest (tea manufacturing) processing can result in aroma formation. Herein, we summarize recent investigations into the biosyntheses of several characteristic aroma compounds prevalent in teas and derived from volatile fatty acid derivatives, terpenes, and phenylpropanoids/benzenoids. Several key aroma synthetic genes from tea leaves have been isolated, cloned, sequenced, and functionally characterized. Biotic stress (such as tea green leafhopper attack) and abiotic stress (such as light, temperature, and wounding) could enhance the expression of aroma synthetic genes, resulting in the abundant accumulation of characteristic aroma compounds in tea leaves. Understanding the specific relationships between characteristic aroma compounds and stresses is key to improving tea quality safely and effectively. [Formula: see text]. PMID- 30277807 TI - Effects of a self-management programme on patient participation in patients with chronic heart failure or chronic obstructive pulmonary disease: A randomized controlled trial. AB - BACKGROUND: Self-management strategies are crucial to patients with long-term conditions and can presumably promote patient participation, given that to patients, patient participation connotes opportunities for self-care (along with being engaged in an exchange of knowledge, a phrasing of joint goals and planning of care). So far, limited attention has been given to what components support self-management and what outcomes can be achieved. An exclusive self-management programme in primary healthcare entailed assessing its influence on patient participation. AIM: To describe the effects of a self-management programme on preferences for, and experiences of, patient participation in patients with chronic obstructive pulmonary disease or chronic heart failure. METHODS: A randomized controlled trial with a six session intervention programme, including phrasing of individual action plans and group discussions on the patients' issues. The intervention group ( n=59) received standard care and the self management programme, and the control group ( n=59) received standard care only. Data was collected at baseline and at three months and 12 months after the intervention started, using the Patient Preferences for Patient Participation (the 4Ps) measure. RESULTS: No significant differences were found within the groups, or between the groups, in preferences and experiences of patient participation, either in summary score or at an item level. CONCLUSION: A self management group programme led by trained primary healthcare staff in primary care did not serve as means to influence patients' experience of patient participation in the care of their long-term condition. Further studies are needed in regard to what facilitates patient participation in this setting and beyond. PMID- 30277808 TI - Lactation Space Experiences and Preferences Among Health Care Workers in an Academic Medical Center. AB - BACKGROUND: Comprehensive workplace lactation support programs can reduce the risk for early breastfeeding discontinuation; however, scant evidence is available to inform user-centered design of employee lactation spaces. This study describes health care workers' preferences for lactation space. MATERIALS AND METHODS: In 2016-2017, a convenience sample of 151 women who pumped at work at an academic medical center reported on demographics, lactation experiences, and room and equipment preferences through an online survey. RESULTS: Respondents worked in research and administration (32%), were nurses (30%), physicians and medical students (19%), or allied health or clinical support staff (19%). Seventy percent had ever used one of the hospital's dedicated lactation spaces. Forty-nine percent ranked hospital-grade pumps the most important piece of lactation room equipment; 83% preferred multiple occupancy lactation suites; and the average maximum acceptable distance to lactation space was 5.6 minutes. CONCLUSIONS: Optimal lactation infrastructure supports the immediate and long-term health of female workers and their children. User needs and preferences can guide design of lactation space to ensure a minimum standard for design, equipment, and distance. Workers may have different preferences depending on roles and experiences; thus, a variety of solutions may be most effective.

PMID- 30277810 TI - Recent advancements in the application of non-thermal plasma technology for the seafood industry. AB - Non-thermal plasma (NTP) is one of the most promising minimal processing methods for the food industry. However up until recently there are limited studies which would report the application and effect of NTP on processed seafood. The objective of this review is to highlight the recent findings and advancements in the application of NTP within the fish and other seafood industry, including direct application of fresh and dried fish and seafood with as well as indirect application of plasma activated water and seafood industry wastewater purification. The article also summarizes the effect of plasma treatment on microbiological quality, physicochemical and sensory properties and oxidation rate of treated fish and seafood. NTP has high potential to be used within various fields of seafood industry. It is especially effective in treatment of dried seafood products, but the use of plasma activated water during various processing steps such as seafood washing could be also beneficial. Moreover NTP could also be used as a cost effective and environmentally friendly method for seafood wastewater purification. PMID- 30277811 TI - The Antimicrobial Effect of a Commercial Mixture of Natural Antimicrobials Against Escherichia coli O157:H7. AB - Ruminants are important reservoirs of E. coli O157:H7 and are considered as the major source of most foodborne outbreaks (e.g., 2017 outbreak in Germany, 2014 and 2016 outbreaks in United States, all linked to beef products). A promising strategy to reduce E. coli O157 is using antimicrobials to reduce the pathogen levels and/or virulence within the animal gastrointestinal tract and thus foodborne disease. The aim of the study was to determine the efficacy of a commercial mixture of natural antimicrobials against E. coli O157. The minimum inhibitory concentration and minimum bactericidal concentration of the antimicrobial were quantitatively determined and found to be 0.5% and 0.75% (v/v) of the natural antimicrobial, respectively. Microbial growth kinetics was also used to determine the effect of the antimicrobial on the pathogen. The natural antimicrobial affected the cell membrane of E. coli O157, as demonstrated by the increase in relative electric conductivity and increase in protein and nucleic acid release. The antimicrobial was also able to significantly reduce the concentration on E. coli O157 in a model rumen system. Biofilm assays showed that subinhibitory concentrations of the antimicrobial significantly reduced the E. coli 0157 biofilm forming capacity without influencing pathogen growth. In addition, the natural antimicrobial was able to reduce motility and exopolysaccharide production. Subinhibitory concentrations of the antimicrobial had no effect on AI-2 production. These findings suggest that the natural antimicrobial exerts an antimicrobial effect against E. coli O157 in vitro and in a model rumen system and could be potentially used to control this pathogen in the animal gut. The results also indicate that subinhibitory concentrations of the antimicrobial effectively reduce biofilm formation, motility, and exopolysaccharide production.

PMID- 30277813 TI - Genome-Wide DNA Methylation Profile of Gene cis-Acting Element Methylations in All-trans Retinoic Acid-Induced Mouse Cleft Palate. AB - DNA methylation epigenetically regulates gene expression. This study is aimed to investigate genome-wide DNA methylations involved in the regulation of palatal fusion in the all-trans retinoic acid-induced mouse cleft palate model. There were 4,718,556 differentially CCGG methylated sites and 367,504 CCWGG methylated sites for 1497 genes between case and control embryonic mouse palatal tissues. The enhancers (HDAC4 and SMAD3) and promoter (MID1) of these three genes had cis acting element methylation. HDAC4 is localized within the CCWGG, while MID1 and SMAD3 are localized within the CCGG of the gene intron. The methylation-specific polymerase chain reaction data confirmed the MethylRAD-seq results, while the quantitative reverse transcriptase-polymerase chain reaction result showed that changes in gene expression inversely were associated with the cis-acting element methylation of the gene during retinoic acid-induced palatal fusion. The GO and KEGG data showed that these three genes could regulate cell proliferation, skeletal muscle fiber development, and development-related gene signaling or activity. The cis-acting element methylation of HDAC4, SMAD3, and MID1 may play a regulatory role during palatal fusion. Further research is needed to verify these novel epigenetic biomarkers for cleft palate. PMID- 30277814 TI - HIV-Related Stigma by Healthcare Providers in the United States: A Systematic Review. AB - Reducing HIV-related stigma may enhance the quality of HIV prevention and care services and is a national prevention goal. The objective of this systematic review was to identify studies of HIV-related stigma among healthcare providers. For studies published between 2010 and 2017, we: (1) searched databases using our keywords, (2) excluded nonpeer reviewed studies, (3) limited the findings to the provider perspective and studies conducted in the United States, (4) extracted and summarized the data, and (5) conducted a contextual review to identify common themes. Of 619 studies retrieved, 6 were included, with 3 themes identified: (1) attitudes, beliefs, and behaviors (n = 6), (2) quality of patient care (n = 3), and (3) education and training (n = 2). Factors associated with HIV-related stigma varied by gender, race, provider category, and clinical setting. Providers with limited recent HIV-stigma training were more likely to exhibit stigmatizing behaviors toward patients. Developing provider-centered stigma-reduction interventions may help advance national HIV prevention and care goals. PMID- 30277815 TI - HIV Care and Viral Load Suppression After Sexual Health Clinic Visits by Out-of Care HIV-Positive Persons. AB - Outcomes among people living with HIV (PLWH) in New York City (NYC) remain suboptimal. To assess the potential role of the city's sexual health clinics (SHCs) in improving HIV outcomes and reducing HIV transmission, we examined HIV care status and its correlates among HIV-positive SHC patients in NYC. Clinic electronic medical records were merged with longitudinal NYC HIV surveillance data to identify HIV-positive patients and derive their retrospective and prospective HIV care status. Evidence of HIV care and viral load suppression (VLS) after clinic visit were considered outcomes. Logistic regression models were used to assess their correlates. A third of the 1045 PLWH who visited NYC SHCs in 2012 were out of HIV care (OOC) in the 12 months preceding the clinic visit, and were less likely than those previously in HIV care (IC) to have subsequent evidence of HIV care (42% vs. 72%) or VLS in the 12 months after the visit (39% vs. 76%). VLS was particularly low among patients diagnosed with >=2 sexually transmitted infections (46%). The odds of VLS were lowest among those OOC before the clinic visit [versus those IC, adjusted odds ratio (aOR): 0.21, 95% confidence interval (CI): 0.16-0.29], non-Hispanic blacks (versus non Hispanic whites, aOR: 0.58, 95% CI: 0.37-0.90), and residents of high-poverty neighborhoods (>30% vs. <10%, aOR: 0.51, 95% CI: 0.29-0.89). Our findings suggest that SHCs could serve as an intervention point to (re-)link PLWH to HIV care. Real-time provider alerts about patients' OOC status could help achieve that goal. PMID- 30277816 TI - Gender Differences in HIV Testing, Diagnosis, and Linkage to Care in Healthcare Settings: Identifying African American Women with HIV in Chicago. AB - Women account for 25% of all people living with HIV and 19% of new diagnoses in the United States. African American (AA) women are disproportionately affected. Yet, differences in the care continuum entry are not well understood between patient populations and healthcare sites. We aim to examine gender differences in diagnosis and linkage to care (LTC) in the Expanded HIV Testing and Linkage to Care (X-TLC) program within healthcare settings. Data were collected from 14 sites on the South and West sides of Chicago. Multivariate logistic regression analysis was used to determine the differences in HIV diagnoses and LTC by gender and HIV status. From 2011 to 2016, X-TLC performed 281,017 HIV tests; 63.7% of those tested were women. Overall HIV seroprevalence was 0.57%, and nearly one third (29.4%) of HIV-positive patients identified were cisgender women. Of newly diagnosed HIV-positive women, 89% were AA. 58.5% of new diagnoses in women were made at acute care hospitals, with the remainder at community health centers. Women who were newly diagnosed had a higher baseline CD4 count at diagnosis compared with men. Overall, women had lower odds of LTC compared with men (adjusted odds ratio = 0.58, 95% confidence interval 0.44-0.78) when controlling for patient demographics and newly versus previously diagnosed HIV status. Thus, interventions that focus on optimizing entry into the care continuum for AA women need to be explored. PMID- 30277817 TI - Brain iron loading impairs DNA methylation and alters GABAergic function in mice. AB - Iron deficiency is closely associated with altered GABA metabolism and affective behavior. While mutation in the hemochromatosis ( HFE) gene disrupts iron homeostasis and promotes oxidative stress that increases the risk of neurodegeneration, it is largely unknown whether HFE mutation modifies GABAergic homeostasis and emotional behavior. The goal of our study was to investigate the impact of HFE on GABAergic neurochemistry and redox-epigenetic regulation in the brain using H67D HFE-mutant mice that recapitulates the H63D-HFE mutation in humans. H67D mice displayed elevated redox-active iron levels in the brain by 32% compared to age-matched wild-type mice. Moreover, the H67D brain had increased isoprostane and decreased glutathione, indicating elevated oxidative stress. Additionally, the H67D brain had decreased global methylation and attenuated DNA methyltransferase (DNMT) activity. Direct addition of iron to purified DNMT in vitro decreased enzyme activity in a concentration-dependent manner. Last, H67D mice exhibited decreased anxiety-like behavior, which was associated with increased expression of the GABAA receptor alpha2 subunits by 93%, and these changes were also observed in H67D mice fed a low-iron diet. Taken together, our results suggest a putative role of HFE in regulating labile iron status in the brain, and mutation in H67D perturbs redox-methylation status, contributing to GABAergic dysfunction.-Ye, Q., Trivedi, M., Zhang, Y., Bohlke, M., Alsulimani, H., Chang, J., Maher, T., Deth, R., Kim, J.

PMID- 30277818 TI - Long noncoding RNA Plnc1 controls adipocyte differentiation by regulating peroxisome proliferator-activated receptor gamma. AB - Detailed understanding of molecular mechanisms controlling adipogenesis is of great importance to identify new targets for treating obesity. Emerging evidence suggests that long noncoding RNAs (lncRNAs) may play a pivotal role in adipogenesis. Here, we have identified a novel lncRNA, Plnc1, which is transcribed from a position ~25,000 bp upstream of the peroxisome proliferator activated receptor gamma2 ( PPAR-gamma2) gene. Plnc1 is abundantly expressed in adipose tissue, and obese mice have higher Plnc1 expression in adipose tissue than nonobese mice. Plnc1 was induced in established adipogenic lines ST2, 3T3 L1, and C3H10T1/2 as well as in bone marrow stromal cells (BMSCs) after adipogenic treatment. Plnc1 knockdown blocked differentiation of ST2 cells and BMSCs into mature adipocytes, along with the reduction of PPAR-gamma, CCAAT/enhancer binding protein-alpha, and adipocyte protein 2. Conversely, overexpression of Plnc1 promoted ST2 cells and BMSCs to fully differentiate. Mechanism studies revealed that Plnc1 could reduce the methylation level of CpG region in the PPAR-gamma2 promoter and enhance the transcriptional activity of the promoter and thereby increase PPAR-gamma2 transcription. Our study suggests that Plnc1 promotes adipogenic differentiation through controlling the key adipogenic transcription factor PPAR-gamma and highlights the potential of Plnc1 as a target for new therapies to control metabolic disorders like obesity.-Zhu, E., Zhang, J., Li, Y., Yuan, H., Zhou, J., Wang, B.

PMID- 30277819 TI - Suppression of AMPK/aak-2 by NRF2/SKN-1 down-regulates autophagy during prolonged oxidative stress. AB - NF-E2-related factor 2 (NRF2) transcription factor has a fundamental role in cell homeostasis maintenance as one of the master regulators of oxidative and electrophilic stress responses. Previous studies have shown that a regulatory connection exists between NRF2 and autophagy during reactive oxygen species generated oxidative stress. The aim of the present study was to investigate how autophagy is turned off during prolonged oxidative stress, to avoid overeating and destruction of essential cellular components. AMPK is a key cellular energy sensor highly conserved in eukaryotic organisms, and it has an essential role in autophagy activation at various stress events. Here the role of human AMPK and its Caenorhabditis elegans counterpart AAK-2 was explored upon oxidative stress. We investigated the regulatory connection between NRF2 and AMPK during oxidative stress induced by tert-butyl hydroperoxide (TBHP) in HEK293T cells and C. elegans. Putative conserved NRF2/protein skinhead-1 binding sites were found in AMPK/aak-2 genes by in silico analysis and were later confirmed experimentally by using EMSA. After addition of TBHP, NRF2 and AMPK showed a quick activation; AMPK was later down-regulated, however, while NRF2 level remained high. Autophagosome formation and Unc-51-like autophagy activating kinase 1 phosphorylation were initially stimulated, but they returned to basal values after 4 h of TBHP treatment. The silencing of NRF2 resulted in a constant activation of AMPK leading to hyperactivation of autophagy during oxidative stress. We observed the same effects in C. elegans demonstrating the conservation of this self-defense mechanism to save cells from hyperactivated autophagy upon prolonged oxidative stress. We conclude that NRF2 negatively regulates autophagy through delayed down regulation of the expression of AMPK upon prolonged oxidative stress. This regulatory connection between NRF2 and AMPK may have an important role in understanding how autophagy is regulated in chronic human morbidities characterized by oxidative stress, such as neurodegenerative diseases, certain cancer types, and in metabolic diseases.-Kosztelnik, M., Kurucz, A., Papp, D., Jones, E., Sigmond, T., Barna, J., Traka, M.

PMID- 30277820 TI - Galectin-1 promotes choroidal neovascularization and subretinal fibrosis mediated via epithelial-mesenchymal transition. AB - VEGFA and TGF-beta are known major angiogenic and fibrogenic factors. Galectin-1, encoded by lectin, galactoside-binding, soluble ( LGALS) 1, has attracted growing attention for its facilitatory role in angiogenesis and fibrosis through its modification of VEGFA and TGF-beta receptor signaling pathways. We reveal galectin-1 involvement in the mouse model of laser-induced choroidal neovascularization (CNV) and subretinal fibrosis, both of which represent the pathogenesis of age-related macular degeneration (AMD). Neither deletion nor overexpression of Lgals1 affected physiologic retinal development or visual function. Galectin-1/ Lgals1 was upregulated by CNV induction, whereas deletion of Lgals1 suppressed CNV together with downstream molecules of VEGF receptor (VEGFR)2. Loss of Lgals1 also attenuated subretinal fibrosis, expression of epithelial-mesenchymal transition (EMT) markers including Snai1, and phosphorylation of SMAD family member 2. Supporting these in vivo findings, silencing of LGALS1 in human retinal pigment epithelial (RPE) cells inhibited TGF beta1-induced EMT-related molecules and cell motilities. Conversely, overexpression of Lgals1 enhanced CNV and subretinal fibrosis. Specimens from patients with AMD demonstrated colocalization of galectin-1 with VEGFR2 in neovascular endothelial cells and with phosphorylated SMAD2 in RPE cells.

PMID- 30277822 TI - TP and/or EP3 receptors mediate the vasoconstrictor and pressor responses of prostaglandin F2alpha in mice and/or humans. AB - The vasoconstrictor and/or pressor effects of prostaglandin (PG)F2alpha participate in the development of vascular pathologies and limit the clinical use of the agent. This study aimed to determine the receptor types responsible for the vasoconstrictor activity of PGF2alpha and whether they mediate the pressor response evoked by the prostanoid under in vivo conditions. Experiments were performed on genetically altered mice and/or on vessels from these mice or humans. Here we show that deletion of the thromboxane-prostanoid receptor (TP-/-) abolished or drastically diminished the contraction to PGF2alpha in isolated mouse vessels (some of which were resistance arteries) and reduced the elevation in blood pressure evoked by the prostanoid under in vivo conditions. In accordance, TP antagonism abolished the contraction in small arteries of human omentum. Further deletion of E prostanoid receptor type 3 (EP3-/-) removed the PGF2alpha-evoked contraction that remained in some TP-/- arteries and added to the effect of TP-/- on the elevation in blood pressure evoked by the prostanoid under in vivo conditions. In contrast, the uterine contraction to PGF2alpha mediated via the F prostanoid receptor (FP) was unaltered in TP-/-/EP3-/- mice. These results demonstrate that the non-FP receptors TP and/or EP3 mediate the vasoconstrictor and pressor effects of PGF2alpha, which are still of concern under clinical conditions.-Liu, B., Li, J., Yan, H., Tian, D., Li, H., Zhang, Y., Guo, T., Wu, X., Luo, W., Zhou, Y. TP and/or EP3 receptors mediate the vasoconstrictor and pressor responses of prostaglandin F2alpha in mice and/or humans. PMID- 30277821 TI - Calorie restriction prevents diet-induced insulin resistance independently of PGC 1-driven mitochondrial biogenesis in white adipose tissue. AB - Calorie restriction (CR) exerts remarkable, beneficial effects on glucose homeostasis by mechanisms that are not fully understood. Given the relevance of white adipose tissue (WAT) in glucose homeostasis, we aimed at identifying the main cellular processes regulated in WAT in response to CR in a pathologic context of obesity. For this, a gene-expression profiling study was first conducted in mice fed ad libitum or subjected to 40% CR. We found that the gene network related to mitochondria was the most highly upregulated in WAT by CR. To study the role that increased mitochondrial biogenesis plays on glucose homeostasis following CR, we generated a mouse model devoid of the coactivators peroxisome proliferator-activated receptor gamma coactivator 1 (PGC-1)alpha and PGC-1beta specifically in adipocytes. Our results show that mice lacking PGC-1s in adipocytes are unable to increase mitochondrial biogenesis in WAT upon CR. Despite a blunted induction of mitochondrial biogenesis in response to calorie deprivation, mice lacking adipose PGC-1s still respond to CR by improving their glucose homeostasis. Our study demonstrates that PGC-1 coactivators are major regulators of CR-induced mitochondrial biogenesis in WAT and that increased mitochondrial biogenesis and oxidative function in adipose tissue are not required for the improvement of glucose homeostasis mediated by CR.-Pardo, R., Vila, M., Cervela, L., de Marco, M., Gama-Perez, P., Gonzalez-Franquesa, A., Statuto, L., Vilallonga, R., Simo, R., Garcia-Roves, P.

PMID- 30277823 TI - The Forkhead Box C1, a Novel Negative Regulator of Osteogenesis, Plays a Crucial Role in Odontogenic Differentiation of Dental Pulp Stem Cells. AB - The forkhead box C1 (Foxc1) protein, a member of the forkhead/winged helix transcription factor family, is required in stem cell developmental processes. Recently, multiple studies have indicated the crucial role of Foxc1 in mesenchymal stem cell differentiation, but the precise effects and mechanisms on dental pulp stem cells (DPSCs) remain unclear. In this study, we evaluate the role of Foxc1 on the odontogenic differentiation and proliferation of DPSCs. Our results show that Foxc1 decreases time dependently in odontogenic differentiation of DPSCs. Meanwhile, overexpression of Foxc1 could significantly inhibit the mineralization of DPSCs and the expression of odontogenic-related genes, such as runt-related transcription factor 2 (Runx2), dentin sialophosphoprote (DSPP), and dentin matrix acidic phosphoprotein 1 (DMP-1). Foxc1 overexpression does not significantly alter the proliferation of DPSCs. In addition, Foxc1 reduces the expression of p-Smad1/5, an important modulator of bone morphogenetic protein (BMP)/Smad signaling pathway, inhibiting BMP/Smad signaling pathway. In conclusion, our data demonstrated that Foxc1 inhibits odontogenic differentiation of DPSCs and odontogenic-related gene expression through the BMP/Smad signaling pathway which may be useful for the dental regeneration and repair. PMID- 30277824 TI - Attempting to Convert Primed Porcine Embryonic Stem Cells into a Naive State Through the Overexpression of Reprogramming Factors. AB - Establishing pig embryonic stem cells (pESCs) remains a challenge due to differences in the genetic backgrounds of mouse, human, and pig. Therefore, pig specific pluripotency markers and cellular signaling must be identified. In this study, doxycycline (DOX)-inducible vectors carrying Oct4, sex-determining region Y-box 2 (Sox2), Nanog, Kruppel-like family 4 (Klf4), or Myc, which are known reprogramming factors, were transduced into pESCs. And pluripotency genes were analyzed in one or two reprogramming factor-expressed pESCs. When cultured without DOX, pESCs were stably maintained in basic fibroblast growth factor supplemented media. However, when treated with DOX, the cells lost their alkaline phosphatase (AP) activity and differentiated within 2 weeks. Subsequently, we investigated the expression of genes related to pluripotency in DOX-treated pESCs using quantitative reverse transcription-polymerase chain reaction (PCR). Expression levels of Oct4, E-cadherin, and Fut4 were significantly increased by Oct4 overexpression, and Oct4 and Fut4 were upregulated in the Sox2-infected group. When a combination of two reprogramming factors, including Oct4 or Sox2, was introduced, weak AP activity remained. In addition, several of the two reprogramming factor transduction groups could be maintained after subculturing with transgene activation. Although long-term culture failed, pESCs transduced with Oct4 and Nanog, Oct4 and Klf4, or Sox2 and Nanog combinations could be subcultured even under transgene activation conditions. Analysis of the cause of long-term culture failure by quantitative PCR confirmed that the expression of intermediate reprogramming markers was not maintained. Given these results, additional methods are needed to support the completion of each reprogramming phase to succeed in the conversion of the pluripotent state of pESCs. This study improves our understanding of pluripotent networks and can be used to aid in the establishment of bona fide pig pluripotent stem cells.

AB - Brucellosis, caused by bacteria in the genus Brucella, is an infectious zoonosis affecting animals and humans worldwide. Free-ranging Rocky Mountain elk ( Cervus canadensis nelsoni) and bison ( Bison bison) in the Greater Yellowstone Ecosystem (areas of southwestern Montana, eastern Idaho, and northwestern Wyoming, USA) are the self-sustaining reservoirs of bovine brucellosis ( Brucella abortus) and elk are considered the primary source of livestock infections. It has been hypothesized that Brucella-exposed elk might have different physiologic status (pregnancy rates and body condition) and migration behaviors than would healthy elk. Here we tested the effects of brucellosis serologic status on pregnancy rates and winter ingesta free body fat of 100 female elk in southwestern Montana. We also evaluated the effects of serologic status on two characteristics of spring migration behavior, migration types (migrant, mixed migrant, resident, disperser, nomad, and undetermined type) and timing (start and end dates and duration). The migration behaviors were quantified using a model-driven approach based on the relative net squared displacement. We detected a significant difference (P=0.003) in pregnancy rates between seropositive and seronegative elk, with about a 30% drop in seropositive individuals. However, we did not detect differences in body fat between seropositive and seronegative elk or differences in either migration type or timing of spring migration. These results confirmed that the major effect of brucellosis in free-ranging elk is associated with reproduction. PMID- 30277829 TI - Presumed Photoreceptor Dysplasias In Peregrine Falcons ( Falco peregrinus) and Peregrine Falcon Hybrids. AB - We describe a case series of photoreceptor dysplasia with secondary retinal degeneration in juvenile peregrine falcons. Six Peregrine Falcons ( Falco peregrinus) and three Peregrine Falcon * Prairie Falcon ( Falco mexicanus) hybrids had early-life visual deficits. Eight birds had visual defects shortly after hatching, and one bird had visual deficits first noticed at 5 mo of age. Complete ophthalmic examinations were performed in each animal. Eight of the animals had electroretinograms, and nine of the animals had their eyes examined histologically after euthanasia. Ophthalmic examinations did not reveal consistent and potentially blinding abnormalities, including an absence of ophthalmoscopic retinal lesions. Electroretinographic findings included subnormal amplitudes (with rod responses more abnormal than cone responses), with a negative b-wave amplitude occurring in one bird. Histologically, a reduction in the number of photoreceptors was present with numerous degenerative changes to the remaining photoreceptors, including frequent blunting and disorganization of photoreceptor outer segments, decreased numbers of cells in the inner nuclear layer, decreased numbers of ganglion cells, decreased thickness of the nerve fiber layer, and decreased myelinated axons within the optic nerve. Ultrastructurally, only minor cone outer segment changes and occasional phagocytic cells were seen. Results strongly suggested a primary retinopathy, characterized by photoreceptor dysplasia and secondary retinal degeneration with loss of cellular elements throughout the retina. The presence of a similar spectrum of findings in related individuals, the early age of onset, and the relative lack of other environmental, ocular, or systemic abnormalities suggested possible heritability. PMID- 30277830 TI - First Report of Extended-Spectrum Betalactamase-Producing Klebsiella pneumoniae Among Fecal Carriage in Iran: High Diversity of Clonal Relatedness and Virulence Factor Profiles. AB - Increasing rate of silent intestinal carriers with extended-spectrum betalactamase (ESBL)-producing Klebsiella pneumonia (ESBL-KP) has given rise to a serious healthcare problem in clinical settings. Various epidemiological studies are being conducted to determine clonal relatedness among carriers. In this study, we investigated the intestinal carriage of ESBL-KP and clonal relatedness among ESBL-KP isolated from fecal carriage in Iran for the first time. A total of 120 rectal swabs (RSs) were collected including 61 from inpatients of intensive care unit and 59 from outpatients. ESBL-KP screening was performed using MacConkey agar supplemented with cefotaxime. PCR was done for detection of ESBL, carbapenemase, and virulence factor genes. Conjugation experiments and PCR-based replicon typing were performed. Clonal relatedness was investigated by multilocus sequence typing (MLST) and multiple locus variable number tandem repeat analysis (MLVA). Out of a total of 120 RSs, 18.3% (22/120) ESBL-KP were isolated. The rate of blaCTXM-15 was 81%. ompk35 was the most prevalent virulence gene detected in 86.3% of the isolates. In conjugation experiments, three out of five tested isolates had conjugative plasmids. The most prevalent plasmid types belonged to IncL/M, IncA/C, and Inc FII. The MLST analysis showed that the main sequence types (STs) identified among ESBL-KP isolates were ST147, ST15, and ST16. The isolates were characterized into 4 miniclusters and 11 singletons using MLVA. High heterogeneity among ESBL-KP isolates indicated that this bacterium could be colonized in different sites and easily transferred. Screening of carriers in hospitals and community could help in controlling of infection in the healthcare and community settings. PMID- 30277831 TI - The effect of antigen dose on T cell-targeting vaccine outcome. AB - During the past 3-4 decades, an increasing amount of evidence has pointed to the complex role of the antigen dose or T cell receptor (TCR) stimulation strength on the subsequent type, duration and "flavor" or quality of the response. Antigen dose was initially shown to impact Th1/Th2 bias, and later also shown to differentially affect development and induction of Tregs, Th17, T-follicular helper (Tfh), cells, and others. In recent years the quality of both CD4/8 T cells during infections, cancer and/or autoimmunity has turned out to be critical for subsequent disease outcome. Importantly, different vaccination strategies also lead to different types of T cell responses, and the role of the antigen dose is emerging as an important factor as well as a tool for investigators to utilize in fine-tuning vaccine efficacy. This commentary will highlight essential background of how antigen dose can impact and affect the quality of T cell responses, and discuss how this translates in different vaccine settings. PMID- 30277832 TI - Trypanosoma cruzi in a Mexican Free-Tailed Bat ( Tadarida brasiliensis) in Oklahoma, USA. AB - Trypanosoma cruzi is a vector-borne protozoan parasite that infects seven million individuals in Central and South America and is the etiologic agent of Chagas disease. There are increasing reports of endemic transmission within the southern US. Trypanosoma cruzi occurs in wild raccoons and dogs in Oklahoma, but its endemicity in the state is poorly studied. We suspected Mexican free-tailed bats ( Tadarida brasiliensis) contributed to the endemicity of T. cruzi in Oklahoma due to their annual migration from Central America to their North American maternity roosts. During the summer of 2017, we sampled 361 Mexican free-tailed bats for T. cruzi at three maternity roosts in Oklahoma. We collected wing tissues, extracted T. cruzi DNA, amplified target DNA by PCR using the primers TCZ1/TCZ2, and observed amplification by gel electrophoresis. One juvenile Mexican free-tailed bat was positive for T. cruzi resulting in a 0.27% prevalence in the 361 sampled bats. Our finding of a wild bat naturally infected with T. cruzi in Oklahoma provided insight on the endemicity of T. cruzi in underrepresented endemic areas. The positive sample was sequenced, confirmed as T. cruzi, and uploaded to GenBank (MG869732). Future research will focus on monitoring T. cruzi prevalence in wild bats and insect vectors to better understand the enzootic emergence of this neglected tropical parasite. PMID- 30277833 TI - Affinity of Staphylococcal A and Streptococcal G Proteins to West Indian Manatee ( Trichechus manatus manatus) Immunoglobulins. AB - The West Indian manatee ( Trichechus manatus manatus), a subspecies that inhabits coastal areas of Central and South America, has been listed as a vulnerable species because of the rapid decline in its population. Commercially available immunologic reagents specific for sirenians are lacking, limiting the development of sensitive immunodiagnostic assays. We observed the affinity of the microbial proteins A and G to T. m. manatus immunoglobulins. Manatee serum pools were analyzed using enzyme-linked immunosorbent assay (ELISA) to determine the affinity intensity followed by western blotting to confirm the specific binding of proteins A and G to immunoglobulins. The ELISA demonstrated maximum affinity of both proteins until the serum dilution of 1:12,800, with a similar affinity for both proteins. Because both A and G proteins exhibited affinity to manatee immunoglobulins, they can be used to develop sensitive immunodiagnostic assays for this species, contributing to manatee conversation procedures. PMID- 30277834 TI - Hyperimmune bovine colostrum reduces gastrointestinal carriage of uropathogenic Escherichia coli. AB - Debilitating recurrent urinary tract infections (UTIs) are often associated with gastrointestinal colonisation by uropathogens, such as uropathogenic Escherichia coli (UPEC), suggesting that these populations might be a suitable target for the treatment and prevention of recurrent UTI. However, antimicrobial treatment is generally unable to prevent recurrent UTI, and often selects for multidrug resistant uropathogens in the gut, and causes dysbiosis of the gut, vaginal, and urinary microbiota. Of note, the globally-disseminated multi drug resistant UPEC lineage, ST131, is known to both persistently colonise the gut and the urinary tract, and is associated with antibiotic treatment failure, indicating the need for novel non-antibiotic therapeutics for the treatment of UTI. This study therefore presents hyperimmune bovine colostrum (HBC) as a suitable therapy for the treatment of UPEC gastrointestinal colonisation. This work demonstrates that the vaccination of pregnant cows with inactivated cells from a ST131 UPEC isolate results in a highly specific anti-UPEC HBC, and that this product is able to disrupt the gastrointestinal colonisation of ST131 UPEC in mice. PMID- 30277835 TI - Optimizing cancer immunotherapy: Is it time for personalized predictive biomarkers? AB - Cancer immunotherapy, a treatment that selectively augments a patient's anti tumor immune response, is a breakthrough advancement in personalized medicine. A subset of cancer patients undergoing immunotherapy have displayed robust and long lasting therapeutic responses. Currently, the spotlight is on the use of blocking antibodies against the T-cell checkpoint molecules, cytotoxic T-lymphocyte associated antigen 4 (CTLA-4) and programed cell death-1 (PD-1)/programed death ligand 1 (PD-L1), which have been effectively used to combat many cancers types. Despite the overall enthusiasm, immune checkpoint blockade inhibitors suffer from significant limitations such as high cost, serious toxicity in a substantial proportion of patients, and a response rate as low as 10%-40% in some clinical trials. Consequently, there is an urgent and unmet medical need for companion biomarkers that could both predict the response of individual patients to these therapies, and provide the means for precise monitoring of their therapeutic outcome. In this era of precision medicine, predictive biomarkers are a hot commodity because they can effectively separate responders from non-responders, and spare non-responders from serious therapy-related toxicity. Emerging predictive biomarkers for immune checkpoint blockade are: PD-L1 expression, increased amounts of tumor-infiltrating lymphocytes, increased mutational load and mismatch repair deficiency. Other well-studied biomarkers include inflammatory infiltrate, absolute lymphocyte count and lactate dehydrogenase levels. We review recent progress on predictive cancer biomarkers in immunotherapy, with a special emphasis on serum autoantibodies that have the potential to be personalized for optimal clinical outcomes. PMID- 30277836 TI - Sorafenib inhibits caspase-1 expression through suppressing TLR4/stat3/SUMO1 pathway in hepatocellular carcinoma. AB - Sorafenib has been demonstrated to be a beneficial treatment for advanced hepatocellular carcinoma (HCC). Emerging evidence indicates that caspase-1 activation plays a crucial role in HCC progression. However, the relationship between caspase-1 and sorafenib has rarely been reported. In this study, we showed that caspase-1 was essential for lipopolysaccharide (LPS)-induced epithelial-mesenchymal transition (EMT). Moreover, sorafenib treatment could inhibit LPS-stimulated caspase-1 overexpression through restricting the nuclear transport of p65, which contributed to inactivation of NF-kappaB. Co immunoprecipitation (Co-IP) experiments and immunoblot analysis indicated that sorafenib treatment decreased the SUMOylation of p65 via inhibiting TLR4/stat3/SUMO1 signaling cascades. In conclusion, the results of this study suggest that sorafenib inhibits caspase-1 expression through suppressing the nuclear translocation of p65 and provide new insights into the mechanisms of sorafenib treatment in HCC. PMID- 30277837 TI - Maoberry (Antidesma bunius) Improves Glucose Metabolism, Triglyceride Levels, and Splenic Lesions in High-Fat Diet-Induced Hypercholesterolemic Rats. AB - Excessive consumption of a high-fat diet (HFD) is associated with hypercholesterolemia and cardiovascular disease (CVD). Dark purple maoberry (Antidesma bunius) fruit is a very good source of antioxidants. We investigated the effects of maoberry on immune function, lipid profiles, and oxidative stress in HFD-induced hypercholesterolemia. Seventy-two male Sprague Dawley rats were divided into the normal group fed with standard diet (ND); HFD groups (HF); and low, medium, and high dose of maoberry extract groups and a simvastatin group (HF L, HF-M, HF-H, and HF-S, respectively). Maoberry groups were given maoberry extract at concentrations of 0.38, 0.76, and 1.52 g/kg per day. At the same time, HF-S groups were administered simvastatin 10 mg/kg per day. After 12 weeks of maoberry treatment, significant reductions in body weight and triglyceride levels were observed in HF-L, HF-M, and HF-H groups in comparison with HF groups (P < .05). Obvious negative changes in spleen histology were found in HF groups, but not in maoberry-treated groups. Modest, but not significant, improvements were observed in other lipid profiles, immune cells in peripheral blood, oxidative stress, and antioxidant capacity after maoberry supplementation. In summary, these findings suggest that maoberry was helpful in reducing atherogenic risk factors such as lipid profiles, especially triglyceride, inflammation, oxidative stress related to CVD, and lesions in spleen histopathology. PMID- 30277838 TI - Laparoscopically Assisted Anorectoplasty for Intermediate-Type Imperforate Anus: Comparison of Surgical Outcomes with the Sacroperineal Approach. AB - AIM: This study aimed to compare the surgical outcomes of patients with the intermediate-type imperforate anus who underwent laparoscopically assisted anorectoplasty (LAARP; L group) with those of patients who underwent sacroperineal anorectoplasty (S group). MATERIALS AND METHODS: The medical records of patients with intermediate-type imperforate anus at a single institution between April 1983 and April 2017 were retrospectively reviewed. Fecal continence was evaluated using the clinical assessment score for fecal continence developed by the Japanese Study Group of Anorectal Anomalies (maximum score, 8). RESULTS: Twelve cases (rectobulbar urethral fistula, 7; anal agenesis without fistula, 4; and rectovaginal fistula, 1) were included in the L group versus 14 cases (rectobulbar urethral fistula, 11, and anal agenesis without fistula, 3) in the S group. Age and body weight at the time of surgery and rate of associated anomalies did not differ significantly between the two groups. The total scores for fecal continence 3, 5, and 7 years after anorectoplasty were 4, 5, and 4 points in the L group and 4, 5, and 6 points in the S group, respectively, showing no significant intergroup differences. Mucosal prolapse occurred in 50% of the L group and 29% of the S group (P = .42), but failed rectocutaneous anastomosis and anal stenosis were not identified in either group. CONCLUSIONS: Postoperative fecal continence and the incidence of complications after LAARP were comparable with those after sacroperineal anorectoplasty in patients with intermediate-type imperforate anus. PMID- 30277839 TI - Loss of lipid phosphatase SHIP1 promotes macrophage differentiation through suppression of dendritic cell differentiation. AB - SH2-containing inositol 5'-phosphatase-1 (SHIP1) deficiency in mice results in abnormal myeloid expansion, and proinflammatory conditions in the lung. However, the mechanisms involved in SHIP1-mediated regulation of myeloid differentiation remain unclear. Here we show that SHIP1 is a key regulator of early differentiation for dendritic cells (DCs). We also provide critical evidence to modify the function of SHIP1 in in vitro development of BMDCs using the recent framework of defining DCs. We found that loss of SHIP1 suppresses GM-CSF-induced formation of bone marrow-derived DC (BMDC) colonies, leading to reduced BMDC number in BM cell culture. The number of maturated BMDCs decreased in SHIP1-KO culture, due to reduction of immature BMDCs, suggesting SHIP1 is critical for lineage commitment rather than for maturation from myeloid precursors to DCs. We further showed that F4/80+/MHCIIlow BM macrophage-like cells (BMMs) were the main population of SHIP1-KO BM culture. Treatment of wild-type BM culture with 3 alpha aminocholestane (3AC), a specific inhibitor for functional activity of SHIP1, caused a similar developmental defect in BMDCs as seen in SHIP1-KO cells, resulting in the absence of BMDC colony, and increased number of BMMs in BM culture. In conclusion, our results suggest that differentiation of BMDCs are markedly impaired under SHIP1 deficient condition, which causes skewed development of myeloid lineage cells manifested as pathological conditions associated with an excess of macrophage population. PMID- 30277840 TI - Efflux Pump Inhibitors, Alpha-Tocopherol and Aspirin: Role in Campylobacter jejuni and Campylobacter coli Fluoroquinolone Resistance. AB - This study aimed to investigate how efflux pump activity contributes to high fluoroquinolone (FQ) resistance in Campylobacter jejuni and Campylobacter coli isolates and to evaluate the modulatory effects of alpha-tocopherol and aspirin on FQ phenotypic resistance profiles. Minimum inhibitory concentration (MIC) values were obtained for different FQ agents following exposure to different efflux pump inhibitors (EPIs), including PabetaN (50 MUg/mL), which targets the cmeABC efflux system, and chlorpromazine (45 MUg/mL) and verapamil (120 MUg/mL), which target the MFS efflux system. The modulatory effects of aspirin (100 and 200 MUg/mL) and alpha-tocopherol (4 and 10 MUg/mL) on FQ resistance profiles were examined. PabetaN had no effect on the MIC values of all FQ agents, while MFS efflux system inhibitors reduced the resistance level of different FQ agents and achieved an effect nearly comparable with that of alpha-tocopherol (10 MUg/mL). Aspirin exerted a dose-dependent excitatory effect on phenotypic resistance profiles, and this may raise concerns about its usage in both veterinary and clinical settings. While an efflux system other than cmeABC may play a role in FQ resistance in Campylobacter species, lipophilic substances may represent a new approach for controlling efflux pump activities. PMID- 30277842 TI - Correlates of Perinatal Post-Traumatic Stress Among Culturally Diverse Women with Depressive Symptomatology. AB - Post-traumatic stress disorder (PTSD) is an important and often neglected comorbidity of pregnancy; left untreated, it can lead to serious health complications for the mother and developing fetus. Structured interviews were conducted to identify risk factors of PTSD among culturally diverse women with depressive symptomatology receiving perinatal services at community obstetric/gynecologic clinics. Women abused as adults, with two or more instances of trauma, greater trauma severity, insomnia, and low social support were more likely to present perinatal PTSD symptoms. Perinatal PTSD is prevalent and has the potential for chronicity. It is imperative healthcare providers recognize salient risk factors and integrate culturally sensitive screening, appropriate referral, and treatment services for perinatal PTSD. PMID- 30277841 TI - Assessment of CEP55, PLK1 and FOXM1 expression in patients with bladder cancer in comparison with healthy individuals. AB - This case/control study is aimed at investigating the expression of CEP55, PLK1 and FOXM1 in bladder cancer tissues and comparing it with healthy tissue and their relationship with clinicopathological features of BC. Total RNA was extracted; then, gene expression was performed using real-time PCR relative to 18 s rRNA. 2-DeltaDeltaCT method was used to calculate the relative expression of genes. A significant over expression of FOXM1, PLK1 and CEP55 was observed in tumor samples compared to adjacent and normal bladder tissues (all p = 0.001). Therefore, they may be supposed as potential candidate's biomarkers for early diagnosis and targets for cancer therapy. PMID- 30277843 TI - Genome-Wide Association Studies for Spot Blotch (Cochliobolus sativus) Resistance in Bread Wheat Using Genotyping-by-Sequencing. AB - Spot blotch is a severe biotic menace of wheat caused by Cochliobolus sativus (syn. Bipolaris sorokiniana). Spot blotch is liable to major yield losses in warm humid regions. A genome-wide association study using genotyping-by-sequencing (GBS) markers was conducted to identify genomic regions associated with spot blotch resistance in a diversity panel of 159 spring wheat genotypes. In total, 87,096 GBS markers covering the whole genome, with an average polymorphism information content value of 0.276, were applied. Linkage disequilibrium (LD) analysis indicated that the LD decay extent was approximately 100 Mbp. The panel was evaluated for disease severity (DS) and area under disease progress curve (AUDPC) for 2 years. In total, 24 marker-trait associations (MTA) were identified for DS and AUDPC of spot blotch, with 11 on chromosome 5B, 3 on 3A, 2 on 6B, and 1 each on 1A, 2A, 1D, 2D, 4B, 5A, 7A, and 7B. A marker on chromosome 7B significantly explained 14% of the phenotypic variation of spot blotch severity as well as 11% of AUDPC. Five markers-three on chromosome 5B, one on 3A, and one on 7B-were associated with both DS and AUDPC with R2 ranging from 8 to 12%. Significant MTA can be utilized to develop wheat germplasm with resistance to spot blotch. PMID- 30277844 TI - Rapid, automated characterization of disulfide bond scrambling and IgG2 isoform determination. AB - Human antibodies of the IgG2 subclass exhibit complex inter-chain disulfide bonding patterns that result in three structures, namely A, A/B, and B. In therapeutic applications, the distribution of disulfide isoforms is a critical product quality attribute because each configuration affects higher order structure, stability, isoelectric point, and antigen binding. The current standard for quantification of IgG2 disulfide isoform distribution is based on chromatographic or electrophoretic techniques that require additional characterization using mass spectrometry (MS)-based methods to confirm disulfide linkages. Detailed characterization of the IgG2 disulfide linkages often involve MS/MS approaches that include electrospray ionization or electron-transfer dissociation, and method optimization is often cumbersome due to the large size and heterogeneity of the disulfide-bonded peptides. As reported here, we developed a rapid LC-MALDI-TOF/TOF workflow that can both identify the IgG2 disulfide linkages and provide a semi-quantitative assessment of the distribution of the disulfide isoforms. We established signature disulfide-bonded IgG2 hinge peptides that correspond to the A, A/B, and B disulfide isoforms and can be applied to the fast classification of IgG2 isoforms in heterogeneous mixtures. PMID- 30277846 TI - Sphingolipids and Innate Immunity: A New Approach to Infection in the Post Antibiotic Era? AB - Antibiotic resistance has been demonstrated during the entire duration of antibiotic use even before medical utilization. Increasing resistance within virtually all microbes continues to be a problem. Infection with antibiotic resistant microbes has demonstrated significantly increased morbidity, death, and health-care-associated costs. Given increasing antibiotic resistance, multiple novel agents and approaches are being investigated, including antimicrobial lipids. Sphingosine and ceramide have been demonstrated to play a pivotal role in the innate immunity of the epidermis, oral mucosa, and respiratory epithelium; their role is being investigated currently in uroepithelium. Ceramide has been shown to be pivotal in the regulation of mammalian defense against Pseudomonas aeruginosa and Staphylococcus aureus pathogens commonly encountered in pneumonia. On the other hand, sphingosine appears to be equally pivotal and directly involved in pathogenic defense and has been demonstrated to "rescue" mammals from P. aeruginosa infections. Within this review, we will discuss the role of sphingolipids within innate immunity, pathogen invasion, and bacterial infection. We will discuss the antimicrobial activity of sphingosine and possibility for commercial use as an antimicrobial in the post-antibiotic era. PMID- 30277845 TI - Healthcare utilization following spinal cord injury: Objective findings from a regional hospital registry. AB - OBJECTIVE: The purpose was to describe the prevalence and characteristics of healthcare utilization among individuals with spinal cord injury (SCI) from a Level I trauma center. DESIGN: Retrospective data analysis utilizing a local acute trauma registry for initial hospitalization and merged with the Dallas-Fort Worth Hospital Council registry to obtain subsequent health care utilization in the first post-injury year. SETTING: Dallas, TX, USA. PARTICIPANTS: Six hundred and sixty four patients were admitted with an acute traumatic SCI from January 2003 through June 2014 to a Level I trauma center. Fifty five patients that expired during initial hospitalization and 18 patients with unspecified SCI (defined by ICD-9 with no etiology or level of injury specified) were not included in the analysis, leaving a final sample of 591. OUTCOME MEASURES: Data included demographic and clinical characteristics, charges, and healthcare utilization. RESULTS: Mean age was 46.1 years (+/-18.9 years), the majority of patients were male (74%), and Caucasian (58%). Of the 591 patients, 345 (58%) had additional inpatient or emergency healthcare utilization accounting for 769 additional visits (median of 3 visits per person). Of the 769 encounters, 534 (69%) were inpatient and 235 (31%) were emergency visits not resulting in an admission. The most prevalent ICD-9 codes listed were pressure ulcer, neurogenic bowel, neurogenic bladder, urinary tract infection, fluid electrolyte imbalance, hypertension, and tobacco use. CONCLUSION: Individuals with SCI experience high levels of healthcare utilization which are costly and may be preventable. Increasing our understanding of the prevalence and causes for healthcare utilization after acute SCI is important to target preventive strategies.

The aim of this study was to measure and analyze the micro-architecture and morphometric parameters of the normal odontoid with high-resolution three dimensional (3D) micro-computed tomography (micro-CT). METHODS: Micro-CT scans were obtained from five normal odontoid processes. The scanned data were reconstructed with micro-CT software, and the nutrient foramina and the ossification center of the base of the odontoid were revealed. The trabeculae of the odontoid were measured and divided into four parts to obtain the volume fraction of regions of interest. RESULTS: High-resolution 3D images of the micro structures' parameters were obtained from the odontoid using micro-CT software. The images demonstrated sponge-like trabecular bone, with the trabeculae showing a complex, net-like micro-construction. The subchondral bone plate was of lamella like, compact construction and extended and transformed into a net-like structure with rod-shaped trabeculae arranged radially in all directions. There was a statistically significant difference in the volume fraction compared with the region of interest in the fourth part of the trabeculae and the first part of the odontoid (P < 0.05). The nutrient foramina and the ossification center of the odontoid were also observed. CONCLUSIONS: It is feasible to use high-resolution 3D micro-CT to evaluate the micro-architecture of the normal odontoid. Other studies can benefit from use of the micro-CT images, such as finite element evaluations.

The histopathology, protein expression, and gene expression were assessed to confirm apoptosis in the liver, and then, profiles of the metabolites in zebrafish were investigated by untargeted metabolomic assessment to understand the potential toxicity mechanism of nux vomica. Histopathological observations showed that nux vomica caused damage to liver cells. Western blot results indicated increased expression of activated caspase3, and the result of real-time polymerase chain reaction showed a significant increase in the expression level of caspase-3, caspase-8, and caspase-9 genes (p < 0.05) compared with the control group. The liver injury from nux vomica was linked to the downregulation of amino acid (e.g., proline and alanine) and fatty acid (e.g., palmitoleic acid) metabolism and upregulation of some other fatty acid (e.g., arachidic acid) and purine (e.g., xanthine and uric acid) metabolism. The hepatotoxicity of nux vomica resulted from metabolic pathway disturbances, including small molecules involved in energy, purine, lipids, and amino acid metabolism. PMID- 30277849 TI - Overnight Resident versus 24-hour Attending Radiologist Coverage in Academic Medical Centers. AB - Academic medical centers have long relied on radiology residents to provide after hours coverage, which means that they essentially function with autonomy. In this approach, attending radiologist review of resident interpretations occurs the following morning, often by subspecialist faculty. In recent years, however, this traditional coverage model in academic radiology departments has been challenged by an alternative model, the 24-hour attending radiologist coverage. Proponents of this new model seek to improve patient care after hours by increasing report accuracy and the speed with which the report is finalized. In this article, we review the traditional and the 24-hour attending radiologist coverage models. We summarize previous studies that indicate that resident overnight error rates are sufficiently low so that changing to an overnight attending model may not necessarily provide a meaningful increase in report accuracy. Whereas some centers completely replaced overnight residents, we note that most centers use a hybrid model, and overnight residents work alongside supervising attending radiologists, much as they do during the day. Even in this hybrid model, universal double reading and subspecialist final review, typical features of the traditional autonomous resident coverage model, are generally sacrificed. Because of this, changing from resident coverage to coverage by an attending radiologist that is 24 hours/day, 7 days/week may actually have detrimental effects to patient safety and quality of care provided. Changing to an overnight attending radiologist model may also have negative effects on the quality of radiology resident training, and it significantly increases cost. PMID- 30277850 TI - Changes in nutrient intake and inflammation following an anti-inflammatory diet in spinal cord injury. AB - OBJECTIVE: The objective of the current study was to describe the observed changes in nutrient intakes following a 3-month anti-inflammatory diet, and to explore potential relationships between the change in nutrients and the change in various inflammatory mediators. DESIGN: A secondary analysis of a prior randomized controlled clinical trial. SETTING: Individuals with SCI within the Niagara region. PARTICIPANTS: Twenty individuals with various levels and severities of SCI. INTERVENTION: Three-month anti-inflammatory diet. OUTCOME MEASURES: The change in nutrient intake and corresponding changes to various inflammatory mediators. RESULTS: The treatment group demonstrated a significant reduction in fat intake (P = 0.02), a significant increase in protein intake (P = 0.02), and no change in carbohydrates (P = 0.23) or energy intake (P = 0.10). The treatment group showed a significant increase in some nutrients with established anti-inflammatory properties including vitamins A, C, and E, and omega-3 fatty acids (P < 0.01). Significant reductions in proinflammatory nutrients were observed including trans fatty acids (P = 0.05), caffeine (P < 0.01), and sodium (P = 0.02). The treatment group also showed significant reductions in the proinflammatory mediators interferon-y (P = 0.01), interleukin-1beta (P < 0.01), and interleukin-6 (P < 0.05). Further, several proinflammatory mediators were negatively correlated with anti-inflammatory nutrients, including vitamin A, carotenoids, omega-3 fatty acids, and zinc. CONCLUSION: This study provides evidence that dietary alterations are effective at reducing chronic inflammation in individuals with SCI and provides a preliminary assessment of the related nutrient changes.

AB - We propose a pneumatic bending actuator integrated with a low-melting-point alloy based variable stiffness endoskeleton that can bend at multiple points and maintain its bent shape without power supply. Local stiffness of the soft actuator can be altered by melting or hardening the endoskeleton with electric heat applied through embedded metal wires. Bending points of the actuator can be changed by selecting different points of the endoskeleton to be melted, and the bending angle can be controlled by injected air pressure. The shape of the bent actuator is maintained by hardening the alloy even when pressure is reduced to the initial state. We demonstrate that the actuator can be bent differently with only one pneumatic actuation layer by combining multipoint bending and the shape retention function, and thus the actuator can be used for lifting, holding, and unloading an object. We believe that the simple machinery of the actuator will be useful in programming complicated motions of soft robotic fingers, fins, and tentacles. PMID- 30277852 TI - Change in urodynamic pattern and incidence of urinary tract infection in patients with traumatic spinal cord injury practicing clean self-intermittent catheterization. AB - OBJECTIVE: To observe changes in cystometric parameters in individuals with spinal cord injury (SCI) with neurogenic bladder practicing clean intermittent self-catheterization (CIC) and incidence of urinary tract infection (UTI) in such patients. DESIGN: Prospective, observational study. SETTING: Tertiary Urban Rehabilitation Hospital. PARTICIPANTS: Persons with neurogenic bladder caused by traumatic SCI and practicing CIC. INTERVENTIONS: Clinical evaluation, complete urine analysis, urine culture and sensitivity, ultrasonography of the abdomen and urodynamic study were evaluated at baseline and at follow-up (6 months to 1 year). OUTCOME MEASURES: Detrusor pattern, cystometric capacity, detrusor compliance, detrusor leak point pressure, residual urine, incidence of UTI. RESULTS: Thirty-one participants were included in the study. The baseline cystometric study showed that 15 had overactive detrusor and 16 had detrusor areflexia. The mean cystometric capacity decreased significantly between baseline and follow-up in both the groups but remained within the normal threshold limit, decline being more marked in the overactive detrusor group, who also had more marked decrease in compliance. Mean detrusor leak point pressure was below 40 cm H2O in all participants in both groups at baseline and follow-up. Mean residual urine improved at follow-up in both groups. Incidence of UTI was 2.29 episodes per patient per year, and more frequent in the overactive detrusor group. Escherichia coli was the causative agent in 45%. CONCLUSION: The cystometric capacity and compliance decreased significantly though patients were doing regular CIC and managed on antimuscarinics for detrusor overactivity (DO). UTI is more common in individuals with SCI with DO and E. coli is the most common cause of UTI. PMID- 30277853 TI - A Chromosome 6, not Natural Killer Cell, Contribution to Radiation- and Bleomycin Induced Lung Disease in Mice. AB - Inbred strains of mice differ in susceptibility to both radiation-induced and bleomycin-induced pulmonary fibrosis and these traits have been mapped to a common locus on chromosome 6 which harbors genes of natural killer cell function. To investigate this putative locus of fibrosis susceptibility we assessed the fibrotic response of chromosome-6 consomic mice (B6.6A), and of mice deficient for natural killer cells, C57BL/6J Ly49A transgenic mice, after each of thoracic irradiation and bleomycin treatment via osmotic minipump. Thoracic irradiation resulted in less than 15% survival at 26 weeks in parental strain C57BL/6J and A/J mice, due to the development of pneumonitis with fibrosis in C57BL/6J (B6) mice, and pneumonitis in A/J mice. One hundred percent of consomic B6.6A mice survived at 26 weeks after thoracic irradiation, and developed a fibrosis level similar to that of fibrosis-resistant A/J mice, after irradiation ( P = 0.38) or bleomycin challenge ( P = 0.32). C57BL/6J Ly49A transgenic mice were confirmed through flow cytometric analysis to be deficient in NK cells, but the post irradiation survival of these mice was not significantly different from that of wild-type littermate mice ( P = 0.64). Extent of pulmonary fibrosis by histological examination did not differ between C57BL/6J Ly49A transgenic mice and wild-type littermate mice in response to either irradiation ( P = 0.14) or bleomycin treatment ( P = 0.62). We conclude that chromosome 6 genes, but not NK cells, contribute to the susceptibility to both radiation-induced and bleomycin induced pulmonary fibrosis of C57BL/6J mice. PMID- 30277854 TI - The acute effect of training fire exercises on fire service instructors. AB - Fire service instructors (FSI) regularly experience different types of fire exercises, however the strain experienced from these scenarios is not well understood. This study aims to identify the physiological and perceptual strain of Fire Service Instructors (FSI) to three training exercises: DEMO, ATTACK, COMPARTMENT, and the different roles performed: SETTER, INSTRUCTOR. The study also aims to assess the effect that different exercise patterns over a day (BOX, MULTI, COMBINATION) have on immunological responses. Sixteen FSI (age: 41 +/- 8 years, body mass: 83.7 +/- 6.7 kg, height: 177.0+/-6.7 cm) were recruited, with 10 FSI completing the three exercises. Physiological and perceptual measures were collected prior to and immediately post each exercise. Venous blood samples were collected at the beginning and end of each day. One way analysis of variance (ANOVA) were conducted to assess differences in physiological variables between exercise types, independent samples t-tests were conducted between roles. Day changes in hematological variables were assessed by paired sample t-tests and analyzed by one way ANOVAs to identify differences between exercise patterns. The COMPARTMENT exercise resulted in a greater change in rectal temperature (DeltaTre) (0.49 +/- 0.28 degrees C) than both the DEMO (0.23 +/- 0.19 degrees C, p = 0.045) and ATTACK (0.27 +/- 0.22 degrees C, p = 0.016). Within the COMPARTMENT exercise, the SETTER resulted in a greater DeltaTre and rating of perceived exertion than the INSTRUCTOR (0.67 +/- 0.29 degrees C vs. 0.43 +/- 0.18 degrees C, p = 0.027 and 14 +/- 2 vs. 11 +/- 2, p = 0.001, respectively). Following a day of fire exercises white blood cells (WBC), neutrophils, lymphocytes (LYMPH), monocytes (MONO), platelets (PLT), mean platelet volume (MPV), Interleukin (IL)-6, and cardiac troponin T (cTnT) all increased (p < 0.05). Exercise patterns containing a COMPARTMENT exercise resulted in greater PLT, MPV, and IL-6. Total daily variation in DeltaTre was correlated with post exercise WBC, MONO, and LYMPH. COMPARTMENT exercises produce the greatest physiological strain, with the SETTER role within this exercise causing the greatest DeltaTre. Although predominately physiological responses remain within safe limits. Exercise patterns that include a COMPARTMENT exercise also generate a greater inflammatory response. PMID- 30277855 TI - Regulation of C2C12 Differentiation and Control of the Beating Dynamics of Contractile Cells for a Muscle-Driven Biosyncretic Crawler by Electrical Stimulation. AB - Biosyncretic robots have potential advantages associated with both living organisms and electromechanical systems. Skeletal muscle tissue is a candidate as bioactuators for biosyncretic robots because of its excellent contraction force and controllability. However, the low quality of myoblast (C2C12) differentiation into contractile myotubes and the lack of control research on biosyncretic robots are two of the main challenges in the development of biosyncretic robots. In this study, an approach with circularly distributed multiple electrodes (CEs) is proposed to improve C2C12 differentiation and to control the movement of a myotube-based biosyncretic crawling robot. To analyze the advantages of the proposed CEs, the electrical characteristics of CEs and a pair of traditional parallel stimulation electrodes (PEs) were simulated and compared with each other. Then, to determine the optimal electrical stimulation parameters and demonstrate the superiorities of the proposed CEs, electrical pulses with different parameters were used to stimulate two-dimensional and three-dimensional cells during culture with the proposed CEs and PEs. After this the control characteristics of the muscle tissue by the CEs were investigated from the relevance of pulse width-threshold voltage, voltage-contractility, frequency contractility, and electric field direction-contractility by measuring the real time responses of myotubes to different electrical stimulations. Moreover, to demonstrate the control of biosyncretic robots by the CEs, a biomimetic biosyncretic crawler actuated by myotubes was designed, fabricated, and controlled to move at different speeds by varying directions of electric field. This study not only provides a potential tool for the development and control of biosyncretic robots but is also informative for muscle tissue engineering and cardiomyocyte culture. PMID- 30277856 TI - Structure and N-acetylglucosamine binding of the distal domain of mouse adenovirus 2 fibre. AB - Murine adenovirus 2 (MAdV-2) infects cells of the mouse gastrointestinal tract. Like human adenoviruses, it is a member of the genus Mastadenovirus, family Adenoviridae. The MAdV-2 genome has a single fibre gene that expresses a 787 residue-long protein. Through analogy to other adenovirus fibre proteins, it is expected that the carboxy-terminal virus-distal head domain of the fibre is responsible for binding to the host cell, although the natural receptor is unknown. The putative head domain has little sequence identity to adenovirus fibres of known structure. In this report, we present high-resolution crystal structures of the carboxy-terminal part of the MAdV-2 fibre. The structures reveal a domain with the typical adenovirus fibre head topology and a domain containing two triple beta-spiral repeats of the shaft domain. Through glycan microarray profiling, saturation transfer difference nuclear magnetic resonance spectroscopy, isothermal titration calorimetry and site-directed mutagenesis, we show that the fibre specifically binds to the monosaccharide N-acetylglucosamine (GlcNAc). The crystal structure of the complex reveals that GlcNAc binds between the AB and CD loops at the top of each of the three monomers of the MAdV-2 fibre head. However, infection competition assays show that soluble GlcNAc monosaccharide and natural GlcNAc-containing polymers do not inhibit infection by MAdV-2. Furthermore, site-directed mutation of the GlcNAc-binding residues does not prevent the inhibition of infection by soluble fibre protein. On the other hand, we show that the MAdV-2 fibre protein binds GlcNAc-containing mucin glycans, which suggests that the MAdV-2 fibre protein may play a role in viral mucin penetration in the mouse gut. PMID- 30277858 TI - Taurine dioxygenase (tauD)-independent taurine assimilation in Escherichia coli. AB - On the basis of previous studies on taurine assimilation in Escherichia coli, TauD, an iron- and alpha-ketoglutarate-dependent taurine dioxygenase, has been regarded as an indispensable factor for assimilation. However, we found that tauD deficient strains did not lose their taurine assimilation ability when there was no deletion of ssuD, which encodes a reduced flavin mononucleotide [FMNH(2)] dependent alkanesulfonate monooxygenase, which is responsible for the desulfonation of alkanesulfonates. There were no significant differences in lag phase time, growth rate and final growth yield between the tauD-deficient strain and the tauD wild-type strain. Iron increased the growth rate and final growth yield of the ssuD mutant, but not those of the tauD mutant. The double deletion of tauD and ssuD resulted in the loss of the ability to assimilate taurine. When ssuD was artificially expressed in the double-deletion mutant, the mutant recovered its taurine assimilation ability. These findings indicate that there is another taurine assimilation pathway that is dependent on ssuD but independent of tauD. PMID- 30277857 TI - Comparative transcriptome analyses of magainin I-susceptible and -resistant Escherichia coli strains. AB - Antimicrobial peptides (AMPs) have attracted considerable attention because of their multiple and complex mechanisms of action toward resistant bacteria. However, reports have increasingly highlighted how bacteria can escape AMP administration. Here, the molecular mechanisms involved in Escherichia coli resistance to magainin I were investigated through comparative transcriptomics. Sub-inhibitory concentrations of magainin I were used to generate four experimental groups, including magainin I-susceptible E. coli, in the absence (C) and presence of magainin I (CM); and magainin I-resistant E. coli in the absence (R) and presence of magainin I (RM). The total RNA from each sample was extracted; cDNA libraries were constructed and further submitted for Illumina MiSeq sequencing. After RNA-seq data pre-processing and functional annotation, a total of 103 differentially expressed genes (DEGs) were identified, mainly related to bacterial metabolism. Moreover, down-regulation of cell motility and chaperone-related genes was observed in CM and RM, whereas cell communication, acid tolerance and multidrug efflux pump genes (ABC transporter, major facilitator and resistance-nodulation cell division superfamilies) were up regulated in these same groups. DEGs from the C and R groups are related to basal levels of expression of homeostasis-related genes compared to CM and RM, suggesting that the presence of magainin I is required to change the transcriptomics panel in both C and R E. coli strains. These findings show the complexity of E. coli resistance to magainin I through the rearrangement of several metabolic pathways involved in bacterial physiology and drug response, also providing information on the development of novel antimicrobial strategies targeting resistance-related transcripts and proteins herein described. PMID- 30277859 TI - The challenge of pet therapy in systemic sclerosis: evidence for an impact on pain, anxiety, neuroticism and social interaction. AB - OBJECTIVES: The aim of our study was to evaluate the effect of animal-assisted intervention (AAI), a complementary support to traditional therapies focused on the interaction between animals and human beings, in improving psychological trait, anxiety and pain in a cohort of systemic sclerosis (SSc) patients. METHODS: 42 SSc patients, undergoing iloprost intravenous infusion, were divided in three groups: 1) 14 patients submitted to 20 AAI sessions; 2) 14 patients engaged in alternative social activity (control group 1 - C1); and 3) 14 patients without any alternative activity (control group 2 - C2). All patients underwent Visual Analog Scale (VAS), the State-anxiety (STAI-S) and emotional faces at the beginning (s0) and at the end (s1) of each single session, while General Anxiety State-Trait Anxiety Inventory (STAI-T), Beck Depression Inventory (BDI), Social Interaction Anxiety Scale (SIAS), Eysenck Personality Questionnaire-Revised (EPQ R), the Social Phobia Scale (SPS), the Toronto Alexythymia Scale (TAS-20), the Thought Control Questionnaire (TCQ) were administered at baseline (t0) and at the end of the project (t1). RESULTS: AAI group showed a significant decrease of the anxiety state level in respect to the two control groups (p<0.001). VAS scale resulted lower both in AAI (p < 0.001) and C1 group (p<0.01). Moreover, STAI-T and TAS scores were significantly reduced in AAI group (p<0.001). TCQ scale showed that patients treated with AAI, compared to control group C2, had greater capacity to avoid unpleasant and unwanted thoughts (p<0.05). In AAI group, the EPQ-R test revealed an enhancement of extroversion trait compared to both control groups (p<0.05). CONCLUSIONS: Our data show that AAI significantly reduces pain perception, anxiety, neuroticism and ameliorates patients' social interaction, therefore it may be a useful to allow a better compliance to traditional therapies. PMID- 30277861 TI - Simultaneous inhibition of c-Abl and Src kinases abrogates the exaggerated expression of profibrotic genes in cultured systemic sclerosis dermal fibroblasts. AB - OBJECTIVES: To examine the effects of simultaneous inhibition of c-Abl and Src kinases on the gene expression and in vitro production of profibrotic molecules by dermal fibroblasts from patients with diffuse systemic sclerosis (SSc) of recent onset. METHODS: Dermal fibroblasts from normal individuals or from patients with diffuse cutaneous SSc fulfilling the American College of Rheumatology/EULAR SSc classification criteria were cultured in media containing increasing concentrations of the dual c-Abl and Src kinase inhibitor Bosutinib for 24 h. Total soluble collagen in cell culture supernatants was quantified. Western blots were performed for quantitative assessment of type I collagen, fibronectin, and alpha-smooth muscle actin (alpha-SMA) production. Quantitative PCR was performed to examine the effects of Bosutinib on the expression of profibrotic and TGF-beta-responsive genes in cultured SSc dermal fibroblasts. RESULTS: Simultaneous inhibition of c-Abl and Src kinases with Bosutinib reduced the expression of numerous fibrosis-associated genes including COL1A1, COL1A3, FN, and TGFbeta and the production of the corresponding proteins by SSc dermal fibroblasts. Bosutinib also decreased the transition of normal dermal fibroblasts into activated myofibroblasts induced by TGF-beta as evidenced by reduction of alpha-SMA in cell extracts from normal and SSc dermal fibroblasts. CONCLUSIONS: Simultaneous inhibition of c-Abl and Src kinases with Bosutinib abrogates the exaggerated expression of genes encoding fibrillar collagens, fibronectin, and TGF-beta-responsive genes and reduces type I collagen, fibronectin and alpha-SMA production by SSc dermal fibroblasts in vitro. Bosutinib also abrogates TGF- beta induced transition of normal fibroblasts to activated myofibroblasts. These results indicate that inhibition of c-Abl and Src kinases activity may be an effective disease modifying antifibrotic therapeutic intervention for SSc. PMID- 30277860 TI - Gender differences in early systemic sclerosis patients: a report from the EULAR scleroderma trials and research group (EUSTAR) database. AB - OBJECTIVES: To describe differences in clinical presentation between men and women in a large group of patients with early (<3 years' duration) systemic sclerosis (SSc) according to disease subsets. METHODS: A cross-sectional analysis of the prospective EULAR Scleroderma Trial and Research database (EUSTAR) was performed. Patients fulfilling preliminary ACR 1980 classification criteria for SSc, with less than 3 years from the first non-Raynaud's symptom at first entry, were selected. A group of patients with less than 3 years from the first SSc symptom, including Raynaud's phenomenon, was also analysed. SSc related variables, including antibodies, SSc subsets, disease activity and organ involvement were included. Descriptive and bivariate analyses were performed. RESULTS: A total of 1,027 patients were included, 90% Caucasian, 80% women, and 40% with diffuse cutaneous disease. In early stages of SSc, men showed more frequently than women active disease, diffuse cutaneous subset, anti-Scl-70 antibodies, elevated acute phase reactants, muscular and pulmonary involvement. Differences between men and women were confirmed in the limited, but not in the diffuse SSc subset. The results were similar when 650 patients with less than three years from the first SSc symptom, including Raynaud's phenomenon, were analysed. CONCLUSIONS: In early stages of SSc, men present signs and symptoms of more severe disease. In the limited disease subset, men might appear with clinical features and organ involvement similar to those of the diffuse subgroup. In clinical practice, the identification of such differences might help to select the appropriate management for each particular patient. PMID- 30277862 TI - Randomised, double-blind, placebo-controlled trial of IL1-trap, rilonacept, in systemic sclerosis. A phase I/II biomarker trial. AB - OBJECTIVES: This clinical trial was designed to study the safety and efficacy of blocking IL-1 in skin fibrosis of patients with diffuse cutaneous systemic sclerosis (dcSSc), and to test the hypothesis that inhibition of IL-1 by rilonacept will downregulate expression of the 2G SSc gene biomarker as a surrogate for the modified Rodnan skin score (MRSS). METHODS: 19 dcSSc patients were randomised 2:1 active treatment:placebo in this double blinded trial. Study patients received weekly treatments with either subcutaneous rilanocept 320 mg loading dose at day 0 and then 160 mg for each of the 5 subsequent weekly doses, or placebo. Skin biopsies were taken to test 2G SSc biomarker gene expression at day 0 before treatment and one week after the final study drug dose, comparing gene expression changes between rilonacept- and placebo-treated patients, as well as the change in gene expression at week 6 compared to baseline in rilonacept treated patients. Safety assessments extended to 6 weeks after the final dose of study drug or placebo. Other secondary outcome measures included global and IL-1 regulated gene expression, serum biomarkers and the MRSS. RESULTS: Rilonacept compared to placebo-treated patients did not show any treatment-related effect on the 2G SSc biomarker. Rilonacept treatment also failed to alter IL-6 expression in skin, serum IL-6, C-reactive protein, or CCL18, a marker of IL-6 activity in SSc. CONCLUSIONS: In this small trial we did not observe any effect of blocking IL-1 on clinical skin disease or biomarkers of IL-1 activity. PMID- 30277863 TI - Usefulness of six-minute walk test in systemic sclerosis. AB - The 6-minute walk test (6MWT) is a standardised, feasible and reliable measure of sub-maximal exercise capacity that has never been fully validated in systemic sclerosis (SSc). A variety of data suggest that many non-pulmonary aspects of SSc contribute to the test results, thus blunting the ability of the 6MWT to measure changes in lung function. Sources of variability are a training effect, technician experience, subject encouragement, medication, other activities on day of testing, deconditioning and the effects of musculoskeletal conditions and pain. Another cause of variability is the anatomical site the probe is attached to: a forehead probe is preferable to a finger or earlobe sensor. The indiscriminate use of the 6MWT for all SSc patients is not useful. It should be used in patients with pulmonary involvement, combined with diffusion capacity of the lung for carbon monoxide (DLCO) and its components (membrane diffusion and capillary volume) or the Sclerodermia Health Assessment Questionnaire Disability Index. The use of these combined parameters may indicate the onset of pulmonary hypertension. Recent studies suggest two alternatives to the 6MWT: maximal cardiopulmonary exercise testing and DLCO testing during effort. However, their use must still be validated. PMID- 30277864 TI - Combination therapy with rituximab and mycophenolate mofetil in systemic sclerosis. A single-centre case series study. AB - OBJECTIVES: To describe a single centre experience using combination therapy with rituximab (RTX) and mycophenolate mofetil (MMF) in a prospective series of systemic sclerosis (SSc) patients with pulmonary and cutaneous involvement, rapidly progressive or resistant to conventional therapy. METHODS: RTX was administered in two different regimens (1000 mg fortnightly x 2 or 375 mg/m2/week for 4 consecutive weeks) at baseline and after 6 months, associated with MMF 2000 mg/day continuously. Cutaneous fibrosis was evaluated assessing modified Rodnan Skin Score (mRSS) and pulmonary involvement was evaluated performing pulmonary function tests, diffusing lung capacity for carbon monoxide and chest high resolution computed tomography (HRCT). The radiological extension of the interstitial lung disease (ILD) at HRCT, was assessed with the conventional visual reader-based score (CoVR) and with a computerised-aided method (CaM) using a DICOM soft- ware. RESULTS: Eighteen SSc patients underwent combination therapy (F/M: 10/8, median age 51 years, median duration of disease 27 months). Data from fifteen patients were available at 12-month follow-up. The mRSS showed a significant improvement; a significant increase in forced vital capacity and forced expiratory volume in the first second were also observed. In addition, a signi cant reduction of the extension of ILD was detected when evaluated with CaM. No serious adverse events were observed during the follow-up period. CONCLUSIONS: Despite preliminary results and limited to a small number of patients, our data suggest that therapy with RTX and MMF is well tolerated, safe, and potentially effective for cutaneous and pulmonary involvement in SSc. PMID- 30277865 TI - The association of sociodemographic and disease variables with hand function: a Scleroderma Patient-centered Intervention Network cohort study. AB - OBJECTIVES: Impaired hand function in systemic sclerosis (SSc) is a primary cause of disability and contributes diminished health-related quality of life. The objective of the present study was to evaluate sociodemographic, lifestyle, and disease-related factors independently associated with hand function in SSc. METHODS: Patients enrolled in the Scleroderma Patient-centered Intervention Network Cohort who completed baseline study questionnaires between March 2014 and September 2017 were included. Hand function was measured using the Cochin Hand Function Scale (CHFS). Multiple linear regression analysis was used to identify independent correlates of impaired hand function. RESULTS: Among 1193 participants (88% female), the mean CHFS score was 13.3 (SD=16.1). Female sex (standardised regression coefficient, beta (beta)=.05), current smoking (beta=.07), higher BMI (beta=.06), diffuse SSc (beta=0.14), more severe Raynaud's scores (beta=.23), more severe finger ulcer scores (beta=.23), moderate (beta=0.19) or severe small joint contractures (beta=.20), rheumatoid arthritis (beta=0.07), and idiopathic inflammatory myositis (beta=0.06) were significantly associated with higher CHFS scores (more impaired hand function). Consumption of 1-7 alcoholic drinks per week (beta=-0.07) was associated with lower CHFS scores (less impaired hand function) compared to no drinking. CONCLUSIONS: Multiple factors are associated with hand function in SSc. The presence of moderate or severe small joint contractures, the presence of digital ulcers, and severity of Raynaud's phenomenon had the largest associations. Effective interventions are needed to improve the management of hand function in patients with SSc. PMID- 30277866 TI - Dickkopf-1 is downregulated early and universally in the skin of patients with systemic sclerosis despite normal circulating levels. AB - OBJECTIVES: The activity of the Wnt pathway, a critical mediator of fibrosis, is regulated by Dickkopf-1 (Dkk-1). Dkk-1 is absent from scleroderma skin in contrast to skin from healthy subjects where it is clearly expressed. There are no data on circulating levels and function of Dkk-1 in patients with systemic sclerosis (SSc). Our objectives are to assess: i) circulating and functional levels of Dkk-1 in patients with SSc and ii) whether the striking lack of Dkk-1 skin expression is also evident in a) clinically uninvolved skin from patients with SSc and b) very early disease prior to skin thickening. METHODS: Circulating Dkk-1 levels were measured in 50 patients with SSc and 50 controls. Skin biopsies were obtained from SSc patients from a) clinically involved skin b) clinically uninvolved skin, c) oedematous skin prior to skin thickening. RESULTS: Circulating and functional Dkk-1 levels were similar in patients with SSc and controls. Healthy skin displayed a high Dkk-1 immuno-expression in the epidermis and dermal fibroblasts in contrast to clinically involved scleroderma skin where Dkk-1 was totally absent. In all biopsies of clinically uninvolved skin Dkk-1 was only moderately expressed whereas skin from very early disease displayed only a weak Dkk-1 immunoreactivity. CONCLUSIONS: The downregulation of Dkk-1 at the oedematous phase of the disease indicates that the Wnt pathway is involved early in the disease process and may play a role in driving fibrosis. The decrease in Dkk-1 expression in clinically uninvolved scleroderma skin indicates that skin in SSc is universally affected. PMID- 30277867 TI - Implications of endothelial shear stress on systemic sclerosis vasculopathy and treatment. AB - There are no Federal Drug Administration approved drugs for the treatment of systemic sclerosis vascular digital ulcers (DU) in the United States, which are thought to be an end-stage result of prolonged ischaemia due to severe, prolonged Raynaud's phenomenon. Most therapeutics for vasodilation used in SSc work different pathways to target the smooth muscle to induce vessel relaxation. Longitudinal studies of vascular function allow insight into the effects of medications used for Raynaud's phenomenon in the SSc patient population. In this review, we discuss vascular tone, the function of the endothelium in SSc, and provide the rationale for longitudinal studies of vascular function and therapeutics that target the endothelial shear stress in addition to vasodilation for treatment and prevention of DU. This review provides the rationale for vasodilatory medication use for treatment of SSc-related DU and justifies access to non-FDA approved medications for this indication.

Herewith, we provide an overview of the most significant literature contributions published over the last year. PMID- 30277870 TI - A shared future for all: let's talk about homelessness. PMID- 30277869 TI - The role of inflammatory markers in assessment of disease activity in systemic sclerosis. AB - OBJECTIVES: The role of the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in the assessment of disease activity in systemic sclerosis (SSc) remains controversial. We sought to evaluate the relationship between clinical features of SSc and raised inflammatory markers and to determine if changes in ESR and CRP reflect changes in other disease features over time. METHODS: One thousand, five hundred and forty-five patients enrolled in the Australian Scleroderma Cohort Study were observed over a mean 3.52+/-2.91 years and assessed at 6,119 study visits. Generalised estimating equations were used to determine the relationship between ESR>=20mm/hr and CRP>=5mg/L and features of disease. The associations between change in inflammatory markers and change in skin scores and respiratory function tests were analysed. RESULTS: Overall, there was a significant association between raised ESR and forced vital capacity (FVC)<80% predicted, diffusing capacity of the lung (DLCO)<80% predicted, pulmonary arterial hypertension (PAH), body mass index (BMI), proximal muscle strength, anaemia, and hypocomplementaemia (p<0.05). Raised CRP was significantly associated with modified Rodnan Skin Score>20, FVC<80%, DLCO<80%, PAH, digital ulcers, BMI, synovitis, tendon friction rub, anaemia, and hypocomplementaemia (p<0.05). A significant deterioration in respiratory function tests (RFTs) was associated with a 2-fold increase in both ESR and CRP (p<0.05). CONCLUSIONS: Raised inflammatory markers are associated with pulmonary, cutaneous and musculoskeletal manifestations of SSc. Rising inflammatory markers are correlated with declining respiratory function tests. This suggests inflammatory markers have a role in the assessment of SSc disease activity.

PMID- 30277886 TI - Single nanowire measurements of room temperature ferromagnetism in FeSi nanowires and the effects of Mn-doping. AB - Semiconductors with magnetic response at room temperature are sought for spintronics in solid-state devices. Among possible materials for this applications, the magnetic response of FeSi and doped FeSi have produced contradictory results at the nanoscale and more precise measurements and deeper studies are needed to clarify its potential capabilities. For that reason, in this work, single nanowire measurements of ferromagnetic semiconducting FeSi and Mn-doped FeSi nanostructures have been performed using magnetic force microscopy and electron holography. Results obtained confirm the presence of magnetic domains at room temperature with a magnetic moment per Fe atom of [Formula: see text] Spin polarized density functional calculations confirm a net magnetic moment between [Formula: see text] in Fe surface atoms with an estimated Curie temperature of 417 K by means of the molecular field approximation. The nanowires present a crystalline B20 cubic structure as confirmed by x-ray diffraction and high-resolution electron microscopy. Their electrical transport measurements confirm p-type nature and thermal activation. A remanent magnetization of 1.5 * 10-5 emu and 0.5 * 10-5 emu was measured at room temperature for FeSi and Mn doped FeSi respectively, with spin freezing behavior around 30 K for the Mn-doped nanowires. PMID- 30277887 TI - Effects of acrylate/acrylamide polymers on the adhesion, growth and differentiation of Muse cells. AB - BACKGROUND: Acrylate/acrylamide copolymers have excellent optical properties and biocompatibility and are ideal biomaterials that have been widely used in tissue engineering. Multilineage-differentiating stress-enduring cells (Muse cells) are a specific subset of mesenchymal stem cells that have an excellent potential for the regenerative medicine. OBJECTIVE: This study was designed to investigate the effects of acrylate/acrylamide copolymers on the adhesion, proliferation and pluripotent-like properties of Muse cells, which were derived from normal human dermal fibroblasts by long-term trypsin incubation. METHODS: In an initial experiment, Muse cells were seeded on primary microarrays containing micro-spots of 275 different mixtures of acrylate/acrylamide. Each mixture was composed of two of 11 different monomers in various proportions, and was replicated in four micro-spots each. According to the adhesion and growth characteristics of Muse cells on those substrates, specific polymer candidates for Muse cells were selected and secondary microarrays were prepared. We then observed the effects of those specific polymer candidates on the adherence, proliferation and differentiation of Muse cells and suitable candidates for their optimal culture were identified. RESULTS: According to the adhesion and growth patterns of Muse cells on the primary microarrays, ten suitable mixtures of acrylate/acrylamide copolymers were identified. Muse cells grew well on six of those combinations and around the four other combinations of those polymer mixtures. Muse cells cultured on three of those combinations proliferated and differentiated into long spindle shaped cells that looked like fibroblasts, while Muse cells cultured on one combination formed clusters that were ring-shaped. Muse cells cultured on some of those combinations of acrylate/acrylamide proliferated and formed clusters that appeared to be very healthy, whereas Muse cells cultured on other combinations formed clusters that expanded outwards. CONCLUSIONS: These results identified a polymer combination that was optimum for the adhesion, proliferation and maintenance of Muse cells in an undifferentiated state. PMID- 30277888 TI - Short-term post-implantation dynamics of in vitro engineered human microvascularized adipose tissues. AB - Engineered adipose tissues are developed for their use as substitutes for tissue replacement in reconstructive surgery. To ensure a timely perfusion of the grafted substitutes, different strategies can be used such as the incorporation of an endothelial component. In this study, we engineered human adipose tissue substitutes comprising of functional adipocytes as well as a natural extracellular matrix using the self-assembly approach, without the use of exogenous scaffolding elements. Human microvascular endothelial cells (hMVECs) were incorporated during tissue production in vitro and we hypothesized that their presence would favor the early connection with the host vascular network translating into functional enhancement after implantation into nude mice in comparison to the substitutes that were not enriched in hMVECs. In vitro, no significant differences were observed between the substitutes in terms of histological aspects. After implantation, both groups presented numerous adipocytes and an abundant matrix in addition to the presence of host capillaries within the grafts. The substitutes thickness and volume were not significantly different between groups over the short-term time course of 14 days (d). For the microvascularized adipose tissues, human CD31 staining revealed a human capillary network connecting with the host microvasculature as early as 3 d after grafting. The detection of murine red blood cells within human CD31+ structures confirmed the functionality of the human capillary network. By analyzing the extent of the global vascularization achieved, a tendency towards increased total capillary network surface and volume was revealed for prevascularized tissues over 14 d. Therefore, applying this strategy on thicker reconstructed adipose tissues with rate-limiting oxygen diffusion might procure added benefits and prove useful to provide voluminous substitutes for patients suffering from adipose tissue loss or defects. PMID- 30277889 TI - Reliable gene mutation prediction in clear cell renal cell carcinoma through multi-classifier multi-objective radiogenomics model. AB - Genetic studies have identified associations between gene mutations and clear cell renal cell carcinoma (ccRCC). Since the complete gene mutational landscape cannot be characterized through biopsy and sequencing assays for each patient, non-invasive tools are needed to determine the mutation status for tumors. Radiogenomics may be an attractive alternative tool to identify disease genomics by analyzing amounts of features extracted from medical images. Most current radiogenomics predictive models are built based on a single classifier and trained through a single objective. However, since many classifiers are available, selecting an optimal model is challenging. On the other hand, a single objective may not be a good measure to guide model training. We proposed a new multi-classifier multi-objective (MCMO) radiogenomics predictive model. To obtain more reliable prediction results, similarity-based sensitivity and specificity were defined and considered as the two objective functions simultaneously during training. To take advantage of different classifiers, the evidential reasoning (ER) approach was used for fusing the output of each classifier. Additionally, a new similarity-based multi-objective optimization algorithm (SMO) was developed for training the MCMO to predict ccRCC related gene mutations (VHL, PBRM1 and BAP1) using quantitative CT features. Using the proposed MCMO model, we achieved a predictive area under the receiver operating characteristic curve (AUC) over 0.85 for VHL, PBRM1 and BAP1 genes with balanced sensitivity and specificity. Furthermore, MCMO outperformed all the individual classifiers, and yielded more reliable results than other optimization algorithms and commonly used fusion strategies. PMID- 30277891 TI - County-Level Socioeconomic Disparities in Use of Medical Services for Management of Infections by Medicare Beneficiaries With Diabetes-United States, 2012. AB - OBJECTIVE: To assess county-level socioeconomic disparities in medical service usage for infections among Medicare beneficiaries with diabetes (MBWDs) who had fee-for-service health insurance claims during 2012. DESIGN: We used Medicare claims data to calculate percentage of MBWDs with infections. SETTING: Medicare beneficiaries. PARTICIPANTS: We estimated the percentage of MBWDs who used medical services for each of 3 groups of infections by sex and quintiles of the prevalence of social factors in the person's county of residence: anatomic site specific infections; pathogen-specific infections; and HHST infections (human immunodeficiency virus/acquired immunodeficiency syndrome, viral hepatitis, sexually transmitted diseases, and tuberculosis). MAIN OUTCOME MEASURES: Using quintiles of county-specific socioeconomic determinants, we calculated absolute and relative disparities in each group of infections for male and female MBWDs. We also used regression-based summary measures to estimate the overall average absolute and relative disparities for each infection group. RESULTS: Of the 4.5 million male MBWDs, 15.8%, 25.3%, and 2.7% had 1 or more site-specific, pathogen specific, and HHST infections, respectively. Results were similar for females (n = 5.2 million). The percentage of MBWDs with 1 or more infections in each group increased as social disadvantage in the MBWDs' county of residence increased. Absolute and relative county-level socioeconomic disparities in receipt of medical services for 1 or more infections (site- or pathogen-specific) were 12.9 or less percentage points and 65.5% or less, respectively. For HHST infections, percentage of MBWDs having 1 or more HHST infections for persons residing in the highest quintile (Q5) was 3- to 4-fold higher (P < .001) than persons residing in the lowest quintile (Q1). CONCLUSIONS: Infection burden among MBWDs is generally associated with county-level contextual socioeconomic disadvantage, and the extent of health disparities varies by infection category, socioeconomic factor, and quintiles of socioeconomic disadvantage. The findings imply ongoing need for efforts to identify effective interventions for reducing county-level social disparities in infections among patients with diabetes. PMID- 30277892 TI - Effect of Body Weight-Supported Exercise on Symptoms of Knee Osteoarthritis: A Follow-up Investigation. AB - OBJECTIVE: To examine the long-term effect of participation in a 12-week lower body positive pressure (LBPP)-supported low-load treadmill exercise regime on knee joint pain, physical function, and thigh muscle strength in patients with knee osteoarthritis (OA). DESIGN: Prospective, observational, repeated measures. SETTING: Clinical orthopedic setting. PATIENTS: Nineteen overweight patients with knee OA. INTERVENTION: Participants exercised under low-load treadmill walking conditions 2*/week for 12 weeks using an amount of LBPP support that minimized knee pain while walking for a period of 30 minutes at a set speed of 3.1 mph at 0 degree incline. MAIN OUTCOME MEASURES: Knee pain, function, thigh muscle strength, and body anthropometry were reassessed a minimum of 6 months after completion of the initial exercise regime and compared with results from baseline and postexercise evaluation. RESULTS: Data suggested that: (1) patients were able to maintain improvements in knee joint pain and symptoms; (2) patients continued to report enhanced joint function and improved quality of life; and (3) patients maintained thigh muscle strength gains. Finally, a majority of patients continued to experience significant reductions in acute knee pain during full weight bearing treadmill walking. CONCLUSIONS: Data suggest that improvements in knee pain, joint function, and thigh muscle strength associated with participation in a 12-week LBPP-supported low-load exercise regime were maintained well after cessation of the program. These findings have important implications for the development and refinement of exercise strategies and interventions used in the long-term management of joint symptoms associated with knee OA in overweight patients. PMID- 30277890 TI - Randomized Feasibility Trial of a Low Tidal Volume-Airway Pressure Release Ventilation Protocol Compared With Traditional Airway Pressure Release Ventilation and Volume Control Ventilation Protocols. AB - OBJECTIVES: Low tidal volume (= tidal volume <= 6 mL/kg, predicted body weight) ventilation using volume control benefits patients with acute respiratory distress syndrome. Airway pressure release ventilation is an alternative to low tidal volume-volume control ventilation, but the release breaths generated are variable and can exceed tidal volume breaths of low tidal volume-volume control. We evaluate the application of a low tidal volume-compatible airway pressure release ventilation protocol that manages release volumes on both clinical and feasibility endpoints. DESIGN: We designed a prospective randomized trial in patients with acute hypoxemic respiratory failure. We randomized patients to low tidal volume-volume control, low tidal volume-airway pressure release ventilation, and traditional airway pressure release ventilation with a planned enrollment of 246 patients. The study was stopped early because of low enrollment and inability to consistently achieve tidal volumes less than 6.5 mL/kg in the low tidal volume-airway pressure release ventilation arm. Although the primary clinical study endpoint was PaO2/FIO2 on study day 3, we highlight the feasibility outcomes related to tidal volumes in both arms. SETTING: Four Intermountain Healthcare tertiary ICUs. PATIENTS: Adult ICU patients with hypoxemic respiratory failure anticipated to require prolonged mechanical ventilation. INTERVENTIONS: Low tidal volume-volume control, airway pressure release ventilation, and low tidal volume-airway pressure release ventilation. MEASUREMENTS AND MAIN RESULTS: We observed wide variability and higher tidal (release for airway pressure release ventilation) volumes in both airway pressure release ventilation (8.6 mL/kg; 95% CI, 7.8-9.6) and low tidal volume-airway pressure release ventilation (8.0; 95% CI, 7.3-8.9) than volume control (6.8; 95% CI, 6.2-7.5; p = 0.005) with no difference between airway pressure release ventilation and low tidal volume-airway pressure release ventilation (p = 0.58). Recognizing the limitations of small sample size, we observed no difference in 52 patients in day 3 PaO2/ FIO2 (p = 0.92). We also observed no significant difference between arms in sedation, vasoactive medications, or occurrence of pneumothorax. CONCLUSIONS: Airway pressure release ventilation resulted in release volumes often exceeding 12 mL/kg despite a protocol designed to target low tidal volume ventilation. Current airway pressure release ventilation protocols are unable to achieve consistent and reproducible delivery of low tidal volume ventilation goals. A large-scale efficacy trial of low tidal volume-airway pressure release ventilation is not feasible at this time in the absence of an explicit, generalizable, and reproducible low tidal volume-airway pressure release ventilation protocol. PMID- 30277893 TI - No Difference in Return to Sport and Other Outcomes Between Operative and Nonoperative Treatment of Medial Epicondyle Fractures in Pediatric Upper Extremity Athletes. AB - OBJECTIVE: Compare outcomes of operative and nonoperatively managed medial epicondyle fractures in upper-extremity athletes. DESIGN: Retrospective chart review and phone survey. SETTING: Level 1, tertiary-referral pediatric hospital. PATIENTS: Propensity scores (probability of operative treatment) were estimated from a logistic regression model that included sex, age, displacement, limb dominance, and injury severity (presence of an additional fracture, nerve injury, or elbow dislocation). These were used to match subjects in the operative group to the nonoperative group. MAIN OUTCOME MEASURES: Return to sport, duration of time required to return to sport, pain, range of motion (ROM), need for physical therapy, and complications were recorded for both groups. RESULTS: Twenty-eight nonoperative subjects were matched to 14 operative subjects. There was no significant difference in the proportion of subjects who returned to the same sport (92.9% in each group), performance at preinjury level of competition, or median time to return to play (P = 0.7106). There was no significant difference in functional limitations in social-/work-related activities (P > 0.9999), pain in the past 30 days (P = 0.0640), need for physical therapy (P = 0.5680), ROM limitations (P = 0.0988), difficulty in sleeping (P = 0.4773), or complications (P = 0.4081). CONCLUSIONS: Our study found no statistical difference in outcomes or complications between operative and nonoperatively treated moderately displaced medial epicondyle fractures in adolescent upper-extremity athletes. Our data show that similar outcomes may be achieved with both treatment groups for medial epicondyle fractures in upper-extremity athletes. PMID- 30277894 TI - Talking Tots and the Terrible Twos: Early Language and Disruptive Behavior in Toddlers. AB - OBJECTIVE: The goal of this article is to investigate the association between the 2 most commonly reported parental concerns about young children-disruptive behavior (e.g., irritable, aggressive, and noncompliant behaviors) and language delay in toddlers. To test for salient subgroup differences, individual differences by the sex of the child and family poverty status were examined. METHODS: Participants included 1259 mothers of children between 18 and 36 months of age. Mothers completed questions about their child's language development and disruptive behavior. Information regarding poverty status as well as child age and sex were also collected. RESULTS: Stronger language skills were associated with fewer disruptive behaviors for children between 18 and 36 months of age. This negative association was stronger for females than for males (b = -0.243; t[1251] = -3.555; p < 0.001) and stronger for children living in poverty than for those above the poverty line (b = -2.04; t[1251] = -2.531; p = 0.011). CONCLUSION: Findings from our study suggest a developmental co-occurrence pattern that begins at a very early age. Individual differences suggest that there is substantial heterogeneity in these patterns; longitudinal investigation is needed to uncover causal pathways and underlying mechanisms. Awareness of the association between these 2 developmental domains, about which parents frequently express concerns, is critical to maximizing early detection and intervention.

PMID- 30277895 TI - Performance of the Pediatric Index of Mortality 3 Score in PICUs in Argentina: A Prospective, National Multicenter Study. AB - OBJECTIVE: To assess the performance of the Pediatric Index of Mortality 3 score in a population of children admitted to PICUs in Argentina. DESIGN: Prospective, national, multicenter study. SETTING: Forty-nine PICUs located in Argentina belonging to public and private institutions. PATIENTS: All children between 1 month and 16 years old admitted to the participating PICUs between May 15, 2016, and February 15, 2017. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: A total of 6,602 patients were enrolled in the study. The observed mortality was 8% (531/6,602), whereas mortality predicted by Pediatric Index of Mortality 3 was 6.16% (407 deaths). The standardized mortality rate was 1.3 (95% CI, 1.20-1.42). The area under the receiver operating characteristic curve was 0.83 (95% CI, 0.82 0.85). The Hosmer-Lemeshow test showed that the difference between the mortality observed and the mortality predicted by Pediatric Index of Mortality 3 was statistically significant (chi, 135.63; p < 0.001). CONCLUSIONS: The Pediatric Index of Mortality 3 score adequately discriminated patients who died from those who survived in our population. However, the observed mortality was higher than predicted by the score. The use of an updated instrument such as Pediatric Index of Mortality 3 will allow an actual comparison between pediatric intensive care provided in the country and care provided internationally. This might also allow future planning of pediatric intensive care services in Argentina. PMID- 30277896 TI - Variability in Pediatric Ideal Body Weight Calculation: Implications for Lung Protective Mechanical Ventilation Strategies in Pediatric Acute Respiratory Distress Syndrome. AB - OBJECTIVES: No gold standard for ideal body weight determination in children exists. We aimed to compare four methods of ideal body weight calculation and determine level of agreement between methods and impact of measurement variance on tidal volumes prescribed in mechanically ventilated pediatric acute respiratory distress syndrome. DESIGN: Post hoc analysis of four multicenter pediatric acute respiratory distress syndrome studies. SETTING: Twenty-six academic PICUs. PATIENTS: Five hundred eighty-nine patients. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Ideal body weight was calculated by four common methods: National Center for Health Statistics, McLaren, Moore, and body mass index, and compared in three ways: 1) determine the proportion of the cohort for which each method could successfully calculate ideal body weight; 2) compare the level of agreement between the ideal body weight methods by Bland-Altman analysis; and 3) evaluate the difference in tidal volume when 6 mL/kg ideal body weight was prescribed. We a priori defined the better method to be one that could calculate ideal body weight in most subjects, had good agreement with other methods, and led to a lower tidal volume. Only 55% could have ideal body weight measured by all four methods. National Center for Health Statistics, McLaren, and Moore methods could calculate ideal body weight in greater than or equal to 90%, whereas body mass index method was successful in only 61% because of no body mass index validation in less than 2-year-olds. In comparing each method to the others, there was great variance, particularly in greater than or equal to 10 year-olds. This variance was greatest between Moore and body mass index methods with greater than or equal to 10 kg difference in ideal body weight in some subjects. The McLaren method had the best agreement with all other methods, and yielded similar prescribed tidal volume in 2- to 10-year-olds and lower tidal volume in greater than or equal to 10 years old. CONCLUSIONS: There is substantial variation in calculated ideal body weight among four commonly used methods, particularly in adolescents. Since varying ideal body weight may lead to discrepancies in pediatric acute respiratory distress syndrome care, a standard approach to ideal body weight measurement is needed. We recommend the McLaren method to calculate ideal body weight in children with pediatric acute respiratory distress syndrome until a gold standard method is validated. PMID- 30277898 TI - A Case Report of Preeclampsia Causing Severe Hyponatremia: Rare or Rarely Reported? AB - Preeclampsia presenting as severe hyponatremia is an enigma of modern obstetric practice. The hyponatremia can cause severe maternal neurological morbidity, including cerebral edema and seizures. Neonates, with serum sodium reflecting maternal levels, are also at risk. Despite this, the literature remains ambiguous about its incidence, the pathophysiology is poorly understood, and guidelines on preeclampsia (including those of the American College of Obstetricians and Gynecologists) do not discuss the issue. This case of preeclampsia associated with severe hyponatremia in a laboring woman highlights these issues. PMID- 30277899 TI - Intraoperative Cell Salvage During Transurethral Resection of Prostate: A Case Report. AB - Intraoperative cell salvage (ICS) became commercially available in 1968 and has enjoyed wide uptake. However, its use in transurethral resection of prostate (TURP) remains rare. We describe a 71-year-old man who underwent TURP with incomplete blood cross-matching. He suffered significant hemorrhage requiring return to theater. There was great delay in obtaining appropriately cross-matched blood, due to previous alloimmunization. ICS was used to retrieve blood present in bladder irrigation. This is the first Australian report of ICS use during TURP. This case led to a change in our practice and serves to demonstrate the potential of this technology during emergencies.

PMID- 30277901 TI - Native Adult Hip with Bacterial Septic Arthritis. PMID- 30277902 TI - Cardiorespiratory Fitness, Adiposity, and Heart Rate Variability: The CARDIA Study. AB - PURPOSE: The importance of cardiorespiratory fitness vs. adiposity in determining heart rate variability (HRV) is unclear. METHODS: From CARDIA, an observational cohort study, we included 2,316 participants (mean age 45.2+/-3.6 years at Year 20, 57% female, 43% black) with HRV measured in 2005-06 (Year 20), and graded exercise test duration (GXTd) and adiposity measures (BMI, waist circumference) obtained in 1985-86 (baseline) and 2005-06. HRV measures (standard deviation of all normal RR intervals [SDNN] and square root of the mean of the squares of differences between all successive RR intervals [RMSSD]) were obtained from resting 30-second 12-lead ECGs. Cross-sectional associations between GXTd, adiposity and HRV were assessed at Year 20. Longitudinal changes in GXTd and adiposity measures were categorized as >=10% increase, <10% change (no change), or >=10% decrease. We used multivariable logistic regression to assess associations of GXTd and adiposity measures with unfavorable vs. more favorable HRV (lower 25th percentile vs. upper 75 percentile). RESULTS: A 1-SD increment in GXTd was associated with 22% and 32% lower odds of unfavorable SDNN and RMSSD, respectively; associations remained significant after adjustment for adiposity. A 1-SD increment in adiposity measures was associated with 16-28% higher odds of unfavorable RMSSD; associations were not significant after adjustment for GXTd. Compared with no change/increase in GXTd, longitudinal decrease in GXTd was significantly associated with 55% and 94% higher odds of unfavorable SDNN and RMSSD, respectively, at Year 20. These associations remained significant after adjusting for adiposity. CONCLUSION: Cardiorespiratory fitness may be a stronger determinant of HRV than adiposity. Intervention studies are needed to better determine the differential effects of improved cardiorespiratory fitness vs. weight loss on HRV. PMID- 30277903 TI - Overview of Link Between Inflammatory Bowel Disease and Cardiovascular Disease. AB - Inflammation has been shown to play an increasingly important role in the pathogenesis of atherosclerosis and in precipitating thrombotic events. Inflammatory bowel disease (IBD) is a systemic inflammatory disorder with a wide range of extraintestinal manifestations including a clinically significant increase in the risk of venous thromboembolism compared to matched controls in several studies. The data for the association between IBD and ischemic heart disease are less clear; multiple population-based studies have shown both positive and negative associations between the 2 conditions. While the systemic inflammation should theoretically increase the risk for cardiovascular disease, inflammatory bowel also potentially provides a cardioprotective effect in several ways. Patients with IBD typically enter the healthcare system at an earlier age and experience a lower incidence of obesity, hypercholesterolemia, and hyperlipidemia. Given the complex interplay among the proatherogenic, prothrombogenic, and cardioprotective effects, IBD should be taken into consideration as a nontraditional risk factor for cardiovascular disease in specific subsets of patients. PMID- 30277904 TI - A Glutathione Precursor Reduces Oxidative Injury to Cultured Embryonic Cardiomyocytes. AB - BACKGROUND: Newborn infants are highly vulnerable to oxidative stress. Following birth asphyxia, oxidative injury due to ischemia-reperfusion can result in significant brain and heart damage, leading to death or long-term disability. STUDY QUESTION: The study objective was to evaluate the effectiveness of antioxidant gamma-L-glutamyl-L-cysteine (gammaGlu-Cys) in inhibiting oxidative injury to cultured embryonic cardiomyocytes (H9c2 cells). STUDY DESIGN: Control and gammaGlu-Cys-treated (0.5 mM) H9c2 cells were incubated under 6-hour ischemic conditions followed by 2-hour simulated reperfusion. MEASURES AND OUTCOMES: To quantify oxidative stress-induced apoptosis sustained by cardiomyocytes, lactate dehydrogenase (LDH) release and the presence of cytosolic cytochrome c were measured, as well as the number of secondary lysosomes visualized under electron microscopy. RESULTS: Compared to controls, H9c2 cells coincubated with gammaGlu Cys during ischemia-reperfusion exhibited a significant reduction in both LDH release into the incubation medium [23.88 +/- 4.08 (SE) vs. 9.95 +/- 1.86% of total; P = 0.02] and the number of secondary lysosomes [0.070 +/- 0.009 (SD) vs. 0.043 +/- 0.004 per MUm; P = 0.01]. Inhibition of LDH release with gammaGlu-Cys was the same (P = 0.67) as that of a caspase inhibitor. The significant increase in cytosolic cytochrome c (P = 0.01) after ischemia-reperfusion simulation further supports gammaGlu-Cys's role in apoptosis prevention. CONCLUSIONS: It is concluded that the glutathione precursor gammaGlu-Cys protects cultured embryonic cardiomyocytes from apoptosis-associated oxidative injury.

RESULTS: Direct 4 RCTs (23,021 patients) suggest that edoxaban is noninferior to warfarin in prevention of stroke and systemic embolism [pooled relative risk (RR): 0.65, 95% confidence interval (CI): 0.23-1.81, 2 RCTs] and reduces the risk of cardiovascular mortality (RR: 0.87, 95% CI: 0.78-0.97, 1 RCT), major cardiovascular morbidity (RR: 0.90, 95% CI: 0.82-0.98, 2 RCTs), and major bleeding events (RR: 0.80, 95% CI: 0.71-0.91, 1 RCT) but increases the risk of gastrointestinal bleeding (RR: 1.21, 95% CI: 1.01-1.46, 1 RCT) and anemia (RR: 1.45, 95% CI: 1.05-1.99, 3 RCTs). Edoxaban is superior to warfarin in patients with increased risk of bleeding with warfarin because of variants in CYP2C9 and VKORC1 genes. Indirect evidence does not allow valid conclusions regarding comparative superiority of NOACs. The quality of evidence was downgraded because of reporting bias, small number of events, and indirectness in comparisons. CONCLUSIONS: Edoxaban is a welcome addition to the NOAC's armamentarium. However, the comparative data with other novel NOACs are mostly nonexisting, and urgently needed for better individual patient assessment.

AB - Quadriceps tendon rupture is a rare lesion, occurring most frequently in males over 60 years following a fall or trauma and associated with systemic diseases and risk factors. Bilateral injury is even more uncommon and disabling. The authors report a case of spontaneous bilateral quadriceps tendon rupture, non simultaneous (8 days apart), in a healthy 54-year-old Black male mason, that may be work-related. The patient was included in a 6-month rehabilitation program after surgical repair. Pain control and gait reacquisition were particularly difficult. Following the customized and phased rehabilitation program, the patient achieved the 6-month functional outcomes reported for unilateral rupture. The authors highlight the rehabilitation specificities and challenges of the bilateral lesion and discuss the pathophysiological role of prolonged periods of working in repetitive quadriceps overuse postures on quadriceps tendon rupture.

PMID- 30277912 TI - The Effectiveness of Group-based Physiotherapy-led Behavioral Psychological Interventions on Adults With Chronic Low Back Pain: A Systematic Review and Meta analysis. AB - Group-based physiotherapy-led behavioral psychological interventions (GPBPIs) are an emerging treatment for chronic low back pain (CLBP), but the efficacy of these interventions is uncertain. A review of relevant randomized controlled trials and a meta-analysis was conducted to evaluate the effectiveness of GPBPIs on pain relief in adults with CLBP. Literature databases, Google Scholar, bibliographies, and other relevant sources were searched. Thirteen (13) intervention studies published from 1998 to 2013 were included. The meta-analysis was conducted using RevMan software in accordance with the Cochrane Handbook for Systematic Reviews of Interventions. In reviewing the short term (< 6 months), intermediate (>=6 and <12 months) and longer term (>=12 months) effects of GPBPIs, long-term follow-up evaluations showed large and significant effect sizes (SMD = -0.25, 95%CI: -0.39 to -0.11, I2= 38%, P<0.01). Subgroup analysis indicated that patients from GPBPIs group had the greater short, intermediate and long term pain reduction than patients on waiting listing or usual care group. Compared to other active treatments, GPBPIs showed a small but significant long term pain reduction in patients with CLBP (SMD = -0.18, 95%CI: -0.35 to -0.01, I2= 32%, P= 0.04). In general, GPBPIs may be an acceptable intervention to relieve pain intensity. PMID- 30277914 TI - An Unusual Pattern of Muscular Atrophy In A Case of GNE Myopathy Presenting with Low Back Pain.

AB - Select residency and medical student training programs have developed and researched skill-based workshops, focusing on mastering a surgical or communication skill, however they are less frequently studied in physiatry residency programs. Given the importance of concussion care in physiatric practice, this study sought to measure the effectiveness of a novel sports related concussion workshop. Based on the 5 International Consensus Statement on Concussion in Sport, a six-hour concussion workshop was developed. Participants were administered a pre- and post-workshop questionnaire to gauge level of comfort managing various aspects of concussion, case-based questions to assess participant knowledge, and questions regarding satisfaction with workshop-based training sessions. 16 participants, ranging from PGY-2 to PGY-5, were included in the analyses, with significant gains (p < 0.0001 to p = 0.0045) made in all measures of comfort managing sports-related concussion; the study was unable to detect a statistically significant improvement in knowledge as assessed by the patient vignettes (p = 0.17), but participants did report high levels of satisfaction with workshop-based training sessions. Thus, workshop-based physiatry trainee education sessions can be employed to teach trainees certain skills, or provide comprehensive training in the management of a specific condition. Participants demonstrated improved comfort managing concussion, a trend towards improved knowledge, and a high degree of satisfaction with the content's method delivery.

PMID- 30277918 TI - The struggle for evidence in physical and rehabilitation medicine: publication rate of randomized controlled trials and systematic reviews is growing more than in other therapeutic fields. AB - OBJECTIVE: To evaluate the rate of publication of randomized controlled trials (RCTs), systematic reviews and meta-analysis in Physical and Rehabilitation Medicine (PRM) and its variation over time. DESIGN: We performed a bibliometric study and searched PubMed from inception to 2017, using National Library of Medicine 3 level MeSH terms ("Rehabilitation", "Physical Therapy Modalities" and "Drug Therapy") and filters ("Randomized Controlled Trial", "Systematic Reviews" and "Meta-Analysis"). We used descriptive statistics and we calculated the best fitting regression model for all data considered. RESULTS: The absolute number of published papers is growing in rehabilitation as much as in other treatment fields such as drug therapy. While the rate of growth of publications for all studies relative to PubMed is bigger for drug therapies than for rehabilitation and physical therapy, the rate of growth of RCTs, systematic reviews and meta analysis is significantly greater for rehabilitation and physical therapy (P<0.001). In 2017, 19.3% and 28.2% of the total production of scientific articles for rehabilitation and physical therapy (respectively) was for RCTs and systematic reviews, versus 11.3% for drug therapy. CONCLUSION: Production of the highest form of research evidence (RCTs, systematic reviews and meta-analysis) is continuously increasing in PRM at a higher rate than in other treatment fields like drug therapy. The quality and results of this evidence should be evaluated in future studies. PMID- 30277919 TI - The association of an alpha2C adrenoreceptor gene polymorphism with vasomotor symptoms in African American women. AB - OBJECTIVE: The alpha2C adrenoreceptor deletion 322-325 (ADRA2C del 322-325) polymorphism has been associated with autonomic activity and thermoregulation, which are implicated in the vasomotor symptom (VMS) mechanism. The ADRA2C del (322-325) has higher prevalence in African American women, a group known to experience more frequent and bothersome VMS. We assessed whether the ADRA2C del (322-325) genotype is associated with increased frequency of VMS in African American women. METHODS: DNA samples from African American (N = 400) women participating in the Study of Women's Health Across the Nation (SWAN) were genotyped for the ADRA2C del (322-325) polymorphism. Longitudinal data on VMS were obtained from the SWAN repository. The relation of ADRA2C del (322-325) genotypes (deletion/deletion [D/D]; insertion/deletion [I/D]; insertion/insertion [I/I]) with VMS over the menopausal transition for up to 12 years of follow-up was examined using generalized estimating equations. Primary models considered the outcome of frequent VMS (6 or more days in the prior 2 wk vs VMS <6 d in the prior 2 wk) by stage of menopause. RESULTS: Four hundred DNA samples from African American women were included. Seventy-five women (18.8%) were found to carry the homozygous variant allele (D/D). There was no significant difference in the trajectory of frequent VMS over the menopausal transition between women with D/D and I/I + I/D genotypes (P = 0.39). CONCLUSIONS: In this preliminary study among African American women in SWAN, ADRA2C del (322-325) was not significantly related to self-reported VMS. Further studies are warranted to help us understand the role of the adrenergic system in the physiology of VMS to tailor medical therapy to patient needs. PMID- 30277920 TI - Age and leptinemia association with anxiety and depression symptoms in overweight middle-aged women. AB - OBJECTIVE: The aim of the study was to investigate the effect of menopause and of postmenopausal stages on depression and anxiety symptoms, and whether these symptoms associate with anthropometric, metabolic, and hormonal parameters in midlife women. METHODS: Postmenopausal women (age 50-65), either at early (EPM, n=33) or late (LPM, n = 23) postmenopause, and 23 premenopausal controls (PreM, age 40-50), matched for BMI with the PM groups, were studied. Blood biochemical and hormonal determinations, bioimpedance anthropometry, and depression and anxiety symptoms (Beck's depression [BDI] and anxiety [BAI] inventories) were conducted. RESULTS: The BAI score was higher in both PM groups than in the PreM group. In contrast, only the LPM group showed a significantly elevated BDI score. All groups presented overweight and abdominal obesity, having similar BMI and waist/hip ratio values. Both PM groups showed insulin resistance, whereas only the LPM group presented decreased skeletal muscle mass and basal metabolic rate. Correlation analysis, including all 79 middle-aged women, showed age, percentage body fat, waist/hip ratio, and leptinemia to correlate positively with the anxiety and depression scores. Multivariate regression showed leptin and age to associate positively with depressive- and anxious-like symptoms. CONCLUSIONS: Postmenopausal women presented impaired body composition, energy expenditure, insulin sensitivity, and mental symptoms, in comparison to similarly overweight premenopausal women. Among all the overweight midlife women, these symptoms were more strongly associated with age and leptin levels than with reproductive aging itself. The data indicate that, among overweight middle-aged women with abdominal obesity, the aging process and the development of leptin resistance are associated with impairment of mental health. PMID- 30277921 TI - Effect of high-intensity interval training on body composition and inflammatory markers in obese postmenopausal women: a randomized controlled trial. AB - OBJECTIVES: This study tested whether high-intensity interval training is a time efficient strategy for improving visceral adiposity tissue and inflammatory markers in obese postmenopausal women when compared with combined training. Moreover, we tested whether change in visceral adiposity tissue is associated with alterations in these inflammatory markers. METHODS: Postmenopausal women were randomized in two groups: combined training (n = 13) and high-intensity interval training (n = 13). The combined training group performed 60 minutes of walking at 70% of maximum heart rate and resistance exercises at 70% of one repetition maximum. The high-intensity interval training group performed 28 minutes of high-intensity exercises (> 80% of maximum heart rate). Both groups trained three times a week for 12 weeks. Body composition and inflammatory markers were analyzed with dual-energy x-ray absorptiometry scanning and enzyme linked immunosorbent assay, respectively. RESULTS: All groups reduced body fat percentage (P = 0.026), visceral adiposity tissue (P = 0.027), leptin (P = 0.043), and increased interleukin (IL)-1 receptor antagonist (P < 0.01). The high intensity interval training group reduced visceral adiposity tissue (P = 0.021) in a greater magnitude and increased interleukin-6 (P = 0.037) level when compared with the combined training group. Moreover, the visceral adiposity tissue changes explained the changes in IL-6 (56%; P = 0.002) only in the high intensity interval training group. CONCLUSIONS: These results suggest that high intensity interval training is a time-efficient strategy for improving visceral adiposity tissue and inflammatory markers in obese postmenopausal women. Moreover, we observed that serum cytokine changes, at least in part, depend on visceral adiposity tissue alterations. PMID- 30277922 TI - To the Editor.

PMID- 30277926 TI - A noninvasive indicator for the diagnosis of early hepatitis B virus-related liver fibrosis. AB - BACKGROUND AND AIMS: Liver stiffness measurement (LSM) detected by FibroScan, combined with biochemical indexes, has shown potential values for assessment of liver fibrosis pathological degrees. Here we aimed to investigate a noninvasive method for hepatitis B virus-related liver fibrosis. PATIENTS AND METHODS: In all, 307 patients who underwent liver biopsy and LSM measurement were included. Inflammation grades and fibrosis stages were evaluated according to METAVIR scoring system. Spearman's rank correlation analysis, logistic regression analysis, and receiver operating characteristic (ROC) curves analysis were performed to assess the factors' role in inflammation grades/fibrosis stages. RESULTS: Spearman's rank correlation analysis showed that LSM, alanine aminotransferase (ALT), aspartate aminotransferase (AST), and AST-to-platelet ratio index were positively correlated with inflammation grades and histologic fibrosis stages; platelets showed negative correlation, and AST-to-ALT ratio was not related. Logistic regression analysis indicated that LSM and APRI were risk factors for inflammation grades; LSM was the independent risk factor for fibrosis stages, P<0.0001, odds ratio>1. ROC curve analysis found LSM cutoff values and areas under the curve for the diagnosis of fibrosis scores: 6.95 and 0.804, respectively, for the diagnosis of significant fibrosis (F>=F2); 10.35 and 0.856, respectively, for severe fibrosis (F>=F3); 11.35 and 0.897, respectively, for cirrhosis (F=F4). Considering ALT as a confounding factor, ROC analysis was repeated in patients with normal and elevated ALT separately; the results indicated that when ALT was up to 40 U/l, LSM cutoff value and areas under the curve for the diagnosis of significant fibrosis (F>=F2) were 6.55 and 0.748, respectively. CONCLUSION: This study provided a noninvasive treatment and prevention indicator for early hepatitis B virus-related liver fibrosis.

PMID- 30277929 TI - Genetic factors involved in the bioavailability of tomato carotenoids. AB - PURPOSE OF REVIEW: To provide an update on the genetic factors recently associated with the interindividual variability of tomato carotenoid bioavailability. RECENT FINDINGS: Several clinical studies have demonstrated that the main carotenoids found in tomatoes (lycopene, phytoene, phytofluene, beta carotene, lutein) all display relatively large interindividual variabilities of their bioavailability, with coefficients of variations more than 70%. The bioavailability of the parent molecules, and the blood/tissue appearance of their metabolites, is modulated by numerous proteins, involved in intestinal absorption and metabolism, blood lipoprotein transport or tissue uptake. Several single nucleotide polymorphisms (SNPs) have been associated with the interindividual variability of lycopene, lutein and beta-carotene bioavailability, with six genes consistently shared between the three carotenoids, and in particular one SNP in ELOVL fatty acid elongase 2. The effects of the genetic variants taken separately are relatively low, that is each variant is usually associated with only a few percentage of the variability but multivariate analyses suggest that the additive effect of several genetic variants can explain a significant fraction of tomato carotenoid bioavailability. SUMMARY: Additional studies are needed to improve our knowledge of the genetic determinants of tomato carotenoid bioavailability but progress in this field could one day allow nutritionists to provide more personalized dietary recommendations.

AB - : Methylnaltrexone Reverses Chronic Opioid-induced Constipation: A Randomized, Controlled Trial. By Yuan CS, Foss JF, O'Connor M, Osinski J, Karrison T, Moss J, Roizen MF. JAMA 2000; 283:367-72. Reprinted with permission. CONTEXT: Constipation is the most common chronic adverse effect of opioid pain medications in patients who require long-term opioid administration, such as patients with advanced cancer, but conventional measures for ameliorating constipation often are insufficient. OBJECTIVE: To evaluate the efficacy of methylnaltrexone, the first peripheral opioid receptor antagonist, in treating chronic methadone induced constipation. DESIGN: Double-blind, randomized, placebo-controlled trial conducted between May 1997 and December 1998. SETTING: Clinical research center of a university hospital. PARTICIPANTS: Twenty-two subjects (9 men and 13 women; mean [SD] age, 43.2 [5.5] years) enrolled in a methadone maintenance program and having methadone-induced constipation. MAIN OUTCOME MEASURES: Laxation response, oral-cecal transit time, and central opioid withdrawal symptoms were compared between the 2 groups. RESULTS: The 11 subjects in the placebo group showed no laxation response, and all 11 subjects in the intervention group had laxation response after intravenous methylnaltrexone administration (P<.001). The oral cecal transit times at baseline for subjects in the methylnaltrexone and placebo groups averaged 132.3 and 126.8 minutes, respectively. The average (SD) change in the methylnaltrexone-treated group was -77.7 (37.2) minutes, significantly greater than the average change in the placebo group (-1.4 [12.0] minutes; P<.001). No opioid withdrawal was observed in any subject, and no significant adverse effects were reported by the subjects during the study. CONCLUSIONS: Our data demonstrate that intravenous methylnaltrexone can induce laxation and reverse slowing of oral cecal-transit time in subjects taking high opioid dosages. Low-dosage methylnaltrexone may have clinical utility in managing opioid induced constipation. PMID- 30277931 TI - Lung-protective Ventilation in the Operating Room: Individualized Positive End expiratory Pressure Is Needed! PMID- 30277932 TI - Positive End-expiratory Pressure and Mechanical Power. AB - WHAT WE ALREADY KNOW ABOUT THIS TOPIC: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Positive end-expiratory pressure is usually considered protective against ventilation-induced lung injury by reducing atelectrauma and improving lung homogeneity. However, positive end-expiratory pressure, together with tidal volume, gas flow, and respiratory rate, contributes to the mechanical power required to ventilate the lung. This study aimed at investigating the effects of increasing mechanical power by selectively modifying its positive end-expiratory pressure component. METHODS: Thirty-six healthy piglets (23.3 +/- 2.3 kg) were ventilated prone for 50 h at 30 breaths/min and with a tidal volume equal to functional residual capacity. Positive end-expiratory pressure levels (0, 4, 7, 11, 14, and 18 cm H2O) were applied to six groups of six animals. Respiratory, gas exchange, and hemodynamic variables were recorded every 6 h. Lung weight and wet-to-dry ratio were measured, and histologic samples were collected. RESULTS: Lung mechanical power was similar at 0 (8.8 +/- 3.8 J/min), 4 (8.9 +/- 4.4 J/min), and 7 (9.6 +/- 4.3 J/min) cm H2O positive end-expiratory pressure, and it linearly increased thereafter from 15.5 +/- 3.6 J/min (positive end-expiratory pressure, 11 cm H2O) to 18.7 +/- 6 J/min (positive end-expiratory pressure, 14 cm H2O) and 22 +/- 6.1 J/min (positive end-expiratory pressure, 18 cm H2O). Lung elastances, vascular congestion, atelectasis, inflammation, and septal rupture decreased from zero end-expiratory pressure to 4 to 7 cm H2O (P < 0.0001) and increased progressively at higher positive end-expiratory pressure. At these higher positive end-expiratory pressure levels, striking hemodynamic impairment and death manifested (mortality 0% at positive end-expiratory pressure 0 to 11 cm H2O, 33% at 14 cm H2O, and 50% at 18 cm H2O positive end-expiratory pressure). From zero end-expiratory pressure to 18 cm H2O, mean pulmonary arterial pressure (from 19.7 +/- 5.3 to 32.2 +/- 9.2 mmHg), fluid administration (from 537 +/- 403 to 2043 +/- 930 ml), and noradrenaline infusion (0.04 +/- 0.09 to 0.34 +/- 0.31 ug . kg . min) progressively increased (P < 0.0001). Lung weight and lung wet-to dry ratios were not significantly different across the groups. The lung mechanical power level that best discriminated between more versus less severe damage was 13 +/- 1 J/min. CONCLUSIONS: Less than 7 cm H2O positive end expiratory pressure reduced atelectrauma encountered at zero end-expiratory pressure. Above a defined power threshold, sustained positive end-expiratory pressure contributed to potentially lethal lung damage and hemodynamic impairment.

PMID- 30277935 TI - Chronic obstructive pulmonary disease and sleep: an update on relevance, prevalence and management. AB - PURPOSE OF REVIEW: Despite the importance of sleep in patients with COPD, this is frequently left unassessed in clinical practice. This review is intended to highlight the inter-relationship between COPD and sleep with an overview of the underlying pathophysiology and symptom burden followed by a review of the current management. RECENT FINDINGS: Recent data has indicated that specific respiratory support provided to patients with COPD and sleep disordered breathing improves clinical outcomes. The provision of respiratory support has expanded from established noninvasive ventilation and continuous positive airway pressure therapy to include novel interventions such as nasal high flow therapy. Sleep is impacted in many ways in patients with COPD and this poor sleep quality can be shown to be associated with worse clinical outcomes. Although data to support a causal effect is lacking, there is increasing interest in interventions such as cognitive behavioural therapy to improve patient symptom burden. SUMMARY: Clinicians managing patients with COPD should be alert to and actively elicit symptoms of comorbid sleep disorders. Once diagnosed, these sleep disorders should be actively managed in line with best practice. Research should focus on whether the active management of sleep disturbance improves long-term outcomes in COPD. PMID- 30277937 TI - Epithelioid Hemangioma of the Face. AB - An epithelioid hemangioma is a very rare lesion arising from vascular structures. We encountered 2 cases in atypical locations, one in the orbital and the other in the nasal region. We performed preoperative angiography in addition to the diagnostic imaging recommended in the literature. Angiography highlighted the lesions well, and in one case, it was possible to embolize the arterial trunk of a high-flow lesion. Angiography underscored how such lesions may differ from the vascular perspective, emphasizing the importance of histology in correct diagnosis. Management of both hemangiomas yielded good functional and cosmetic outcomes with no disease recurrence. PMID- 30277938 TI - Anthropometric Evaluation of Periorbital Region and Facial Projection Using Three Dimensional Photogrammetry. AB - INTRODUCTION: Direct anthropometric and three-dimensional (3D) photogrammetry measurements have been used extensively in cleft/craniofacial surgery to assess morphological changes and surgical outcomes. Craniofacial procedures alter the sagittal projection of periorbital bony prominences. Mulliken described a method of measuring their projection relative to the corneal plane but is impractical in clinical practice. Three-dimensional photogrammetry may offer a solution; however, the cornea is not visualized on this. The authors propose to develop new normative measurements of facial projection relative to the pupil. METHODS: Five 3D photographs were taken of 5 individuals using Vectra M5 camera. Facial projection measurements were taken of the sagittal projection of the bilateral periorbital landmarks and nasal radix relative to the pupil using Mirror 3D analysis. Standard deviations (SD) were determined for each subject and laterality. Chi-square tests confirmed all SD <1 mm. Intra and inter-rater reliability were confirmed with an intraclass correlation coefficient assessment. RESULTS: Three male and 2 female subjects were photographed with 5 unique images. Standard deviations of repeat measures of all landmarks were <0.5 mm. Chi-square tests confirmed with statistical significance that SD for all values except for the radix was <1 mm (P<0.05). Intrarater reliability was high for all landmarks (intraclass correlation coefficient coefficients 0.93-0.99). Inter-rater reliability was good for the lateral canthi and excellent for all others. CONCLUSION: This technique demonstrates repeatability with high reliability on serial photographs and is applicable to measuring surgery effects and growth on facial projection. Establishment of age-specific normative values for landmark projection will refine usage applicability in operative planning. PMID- 30277939 TI - Study on Hair Distribution in Healthy Males for Hair Restoration Design. AB - BACKGROUND: The incidence of hair loss among Chinese male has increased to 21.3 per hundred. Hair restoration has been an effective technique. Detailed hair distribution has a tremendous impact on the surgery design. OBJECTIVE: To investigate the pattern of hair distribution in Chinese young adult males. METHODS: A total of 1000 males without hair disease were enrolled. We evaluated the locations of the main anatomical marks at different sites on the scalp and analyzed the hair density and follicular unit structure using the standard photographs and trichoscope. RESULTS: The hairline shapes were classified as: linear (48.7%), linear with central protrusion (27.9%), round (9.8%), round with central protrusion (13.7%). The average height of the median line was 6.78 +/- 0.75 cm, the ratio of the median line and the forehead height was 0.333. The average distance from the parietal whorl to the vertical bimeatal line was 7.05 +/- 3.32 cm, and most of the PWs were on the right (51.4%) and had a clockwise pattern (73.3%). The hair density was 171.12 +/- 18.32 hairs/cm in the vertex. 1 hair follicular units were (75.90% and 56.39%) in anterior hairline and temporal area. CONCLUSION: Our study clearly assisted understanding of scalp anatomy and hair distribution in Chinese young adult males.

AB - BACKGROUND: The chin is the most prominent and median sector of the lower third of the face giving harmony to nose and lips. The authors present the application of piezoelectric scalpel for the correction of different chin deformities. The distinctive characteristics of this device allow the authors to avoid or reduce the immediate genioplasty complications. METHODS: Fifty-five patients of defective chin have been treated from January 2006 to April 2008. Intraoral genioplasty was performed during the correction of dentofacial dysmorphisms or associated with nasal surgery. The authors used a piezoelectric cutting device to perform different osteotomies and if necessary, interpositional graft was used to stabilize bony segments. RESULTS: Piezosurgery has been associated with a fewer number of postoperative complications, especially as regard intraoperative bleeding, nerve injuries (immediate and late), hematomas and seromas, asymmetry (immediate and early). The mean time for completing the complete procedure of genioplasty with piezosurgery was almost the same compared with the saw and drill. CONCLUSION: Genioplasty represents one of the most common ancillary procedures and may be associated with corrective surgery of dentofacial dysmorphisms. Mental nerve injuries, asymmetries, intraoperative bleeding are the main immediate complications of genioplasty. Distinctive characteristics of ultrasonic piezoelectric osteotomy are selective cut of mineralized structure with less risk of vascular and nervous damage (microvibrations), intraoperative precision (thin cutting scalpel and no macrovibrations), blood free site (cavitation effect). In the authors' experience, piezoelectric scalpel, compared with saw and drill, enables them to reduce or avoid immediate complications of chin surgery, helping the surgeon to reach patients' satisfaction. PMID- 30277942 TI - Intracorporeal Septorhinoplasty: Technique and Outcome. AB - OBJECTIVE: Septal deformities usually associated with functional and aesthetic nasal consequences. Multiple techniques were described to correct these deformities. Using less invasive and at the same time competent technique with loge standing results is important. This study aimed to assess intracorporeal correction for septal deviation with assessment of its competence in managing deferent degrees of deviation and to show concomitant patient-dependant internal valve manipulation used. METHODS: Intracorporeal correction of septal deviation was used in 35 patients which was performed at plastic surgery departments of Menoufia University Hospital and Mawada Privet Hospital, Egypt. The study was carried out between July 2014 and July 2017. RESULTS: Thirty-five patients with variable types of septal deformities, 16 of them were females and 19 were males, were included in the study. Age of patients was between 18 and 55 years (mean 24.9, standard deviation 7.9). Etiology was found as follows: 15 (about 43%) posttraumatic septal deviation, 8 (about 23%) patients had postcleft septal deviation, and the remaining 12 had idiopathic septal deviation. Spreader graft was in 22 (about 63%) patients. Septal hematoma followed by septal perforation occurred in 1 patient (2.8%), while dorsal irregularities were found in 3 (8.4%) patients. Recurrent septal deviation occurred in 2 (5.6%) patients. Concerning functional outcome, no residual nasal obstruction was found in all patients with negative Cottle sign postoperative. CONCLUSION: Intracorporeal correction of septal deformities in open rhinoplasty technique is still found to be effective and less invasive option even with sever septal deviation.

AB - OBJECTIV: The authors devised a multiple small incisions minimally invasive technique for use in isolated nonsyndromic sagittal synostosis to achieve better esthetic effect and satisfactory reshaping of the calvarial vault. The purpose of this study is to provide clinicians with new and feasible solution. METHODS: From April 2016 to January 2017, 5 male patients were successfully treated with minimally invasive surgery. The age ranges from 1.5 to 3.3 years. The authors designed 9 short skin linear incisions (2-3 cm long) strategically to disperse in the scalp. The patient was assessed in a series including sex, age of surgery, blood loss, blood transfusion, duration of surgery, postoperative complications, preoperative and postoperative cephalic index (CI), length of stay (LOS), esthetic outcomes, and intellectual developmental quotient (DQ). RESULTS: The shortest operation time is 1.5 hours. The shortest hospital stay is 6 days. The blood loss ranged from 135 to 280 mL. No serious complications occurred during the follow-up time. Postoperative 3-dimensional CT scan showed that the extensive floating bone formed well. Preoperative CI ranged from 64.2 to 68 and postoperatively 69.4 to 74.3. Mental development was tested by children heath care practioners, significantly improving DQ from 67 to 81 preoperatively and 76 to 90 postoperatively. All children receive good esthetic results. CONCLUSION: The new technique is safe and effective. The advantages are satisfactory: calvarial fornix remodeling, less visible appearance of scars, shorter length of surgery, lower mental and financial stress, optimal age for surgery, no endoscopic adjuvant and postoperative helmet are needed. PMID- 30277945 TI - Evaluation of a Sample of Patients With Unilateral Cleft Lip and Palate Treated With a Two-Stage Protocol. AB - The aim of this paper was to assess growth, speech, and aesthetic results at the completion of growth in patients with unilateral cleft lip and palate treated with the 2 stages Milan surgical protocol.Craniofacial growth was evaluated with cephalometric analysis and a theoretical need for orthognathic surgery.Nasolabial appearance was qualitatively assessed using the Asher McDade Aesthetic Index.Speech was assessed using the Gos.Sp.Ass '98 modified for Italian language scoring system.Burden of care was recorded in terms of number of secondary surgical procedures. All of the patients were treated and evaluated at San Paolo Hospital, Smile House, Milan.Fifty-two consecutive patients treated by the same surgeon were recalled, 12 patients did not come for assessment.The first surgical step (average age of 6 months) was cheilorhinoplasty (Millard modified Delaire technique) and soft palate rapair (Pigott). The second step (average age of 35 months) was hard palate and alveolar repair performed simultaneously with an early secondary gengivo alveolo plasty. Fifty-six percent of the patients did not need further surgery after the 2-stage surgery protocol.The 2-stage surgical protocol of Milano, Smile House, seems to be effective for treatment of unilateral cleft lip and palate, with good results in terms of speech, labial appearance, and alveolar cleft management. Nevertheless, maxillary growth was moderately impaired by the protocol.

AB - The true posterior communicating artery (PCoA) aneurysms in the distal portion of the posterior communicating artery are rare. The authors describe a 63-year-old woman with 1 true PCoA aneurysms in the distal portion of the PCoA, which was treated surgically through modified pterional approach. No neurologic deficit was present at the postoperative period. Although endovascular intervention is more and more widely used in the treatment of aneurysms, the authors have also emphasized that true PCoA aneurysms in the distal portion of the PCoA can also be surgically treated in suitable patients. PMID- 30277947 TI - Can Volumetric and Morphological Variants of Sphenoid Sinuses Influence Sinuses Opacification? AB - Improvements in computed tomography and in functional endoscopic sinus surgery have recently increased interest toward paranasal sinus anatomy and anatomic variations that can be observed in patients affected by sinusitis. Isolated sphenoid sinusitis is a relatively rare pathology, often related to nonspecific symptoms, therefore making diagnosis difficult. The correlation between this type of sinusitis and anatomical variants remains unclear.The authors' aim was to retrospectively revise paranasal sinuses computed tomography scans of patients affected by sphenoid sinusitis, compared with a control group, analyzing the types of sphenoid sinus and the presence of aberrant pneumatization, and performing a segmentation of the sphenoid sinuses to calculate the volumes.Sphenoid sinuses of 60 patients affected by sinus opacification, compared with a control group, were segmented. Type of sinus (sellar, presellar, postsellar) and presence of aberrant pneumatization were assessed as well. Possible statistically significant differences in volumes according to sex and group were assessed through 2-way ANOVA test (P < 0.05). Post-hoc test was assessed through Student t test. chi test was applied in order to verify the statistically significance of differences in frequency of different types of sinus pneumatization variants (P < 0.05).Average volume of sphenoid sinuses in males was of 7.672 cm and of 7.751 cm in females within the group of patients; statistically significant differences in volume were found according to sex (P: 0.342), but not between the patients and control group (P: 0.0929). Post-hoc test verified that males affected by sinus opacification showed smaller volumes in comparison with the control males (P < 0.05). In addition, patients by affected sinus opacification showed more frequently the postsellar type and were less affected by pneumatization variants of the sphenoid bone than the control group (P < 0.05).This study first suggests the possible protective role of variants of pneumatization in the development of sphenoid sinus opacification. PMID- 30277948 TI - Reconstruction of Wegener Granulomatosis Nose Deformity Using Fascia Lata Graft. AB - Wegener granulomatosis (WG) is a necrotizing vasculitis that involves the upper respiratory tract, the lungs, and the kidneys. It also causes deformities of the nose in practically all patients, altering the cartilaginous and bony structure as well as the inner lining of the nose.The surgical repair of these nasal distortions is a challenge mainly due to the impairment of wound healing and graft take that is caused both by the disease itself and by the prolonged immunosuppressant treatment.Many different reconstruction plans have been developed, using costal or calvarial bone grafts, cartilage grafts and local skin and mucosa flaps. Results have been diverse.The authors present the case of a 56 year-old patient who suffered from WG and consulted for nasal sequelae. She initially underwent several failed attempts at reconstruction; finally, the authors performed a nasal repair using a double strip of fascia lata as a dorsal graft, with no complications and a good aesthetic result.Fascia lata graft is a new and good option for nasal reconstruction in patients with WG because it is easily obtainable, it can be set in place through closed rhinoplasty and it can achieve good vascularization with low risk of resorption or disease reactivation. PMID- 30277949 TI - Incidence of Foramen Tympanicum (of Huschke): Comparing Cadaveric and Radiologic Studies. AB - PURPOSE: The foramen tympanicum (FT) represents a developmental anomaly that forms due to incomplete fusion of processes of the tympanic ring. Its presence in the population is controversial and it has been associated with a number of otologic complications. The aim of this study was to systematically analyze the prevalence, anatomical characteristics, and ethnic variations of the FT and compare these parameters in cadaveric and radiologic studies. METHODS: An extensive search was conducted through the major electronic databases, and identified articles were separated into 2 groups based on their methodology: cadaveric and radiologic studies. Data extracted included study modality, prevalence data, ethnicity, gender, side, laterality, and diameter. RESULTS: A total of 8 studies (n = 2671 patients) were included into our meta-analysis. The main findings revealed that the prevalence of the FT in the population is 14.9%, it is more often unilateral (62.5%) than bilateral (37.5%), it is most often reported in Asia (21.4%), and it is more prevalent in cadavers (21.2%) than in radiologic studies (8.8%) (not statistically significant). CONCLUSION: As the FT is present in more than one-tenth of the population, it is important to consider the possibilities of its presence when undertaking surgical procedures in the temporomandibular joint and ear region and plan accordingly to avoid injuries. Clinicians should keep it as one of the possible diagnoses while confronted with patients presenting with otologic complications. The use of newer imaging techniques was recommended, such as cone-beam computer tomography to detect the FT prior to surgery. PMID- 30277950 TI - Maxillary Alveolar Ridge Atrophy Reconstructed With Autogenous Bone Graft Harvested From the Proximal Ulna. AB - Atrophy of the alveolar ridge requires bone grafting at the implant site for rehabilitation of the masticatory function with dental implants. Despite the advances in the development of bone substitutes, autogenous bone graft remains the "criterion standard" because of its osteogenic, osteoinductive, osteoconductive potential, and non-immunogenic properties. However, harvesting of autogenous bone is not exempt from donor site morbidity. In this context, the use of autogenous bone derived from the proximal ulna might be a viable resource to obtain corticocancellous bone graft, as the harvesting from this donor site is associated with low morbidity. Thus, this article aimed to describe a case in which a maxillary sinus floor augmentation was performed by means of autogenous bone graft harvested from the proximal ulna, as the donor site. An appositional bone block graft harvested from the same region was used to augment the residual alveolar ridge. Clinically, healing proceeded uneventfully with no major complications. After 8 months, a proper amount of bone was found at the implant site, allowing a prosthetically driven implant insertion and subsequent implant supported rehabilitation. Results were clinically and radiographically stable after a 3-year follow-up. The present case report suggested that proximal ulna as a donor site should be considered as a safe and reliable alternative for alveolar ridge augmentation. Besides the case presentation, a comprehensive review of the literature was also provided. PMID- 30277951 TI - Novel Application of Platelet-Rich Fibrin as a Wound Healing Enhancement in Extraction Sockets of Patients Who Smoke. AB - The objectives of this study were to assess the potential of platelet-rich fibrin (PRF) on acceleration of soft tissue healing after tooth extraction and to evaluate its effectiveness in reducing the prevalence of dry socket among smoker patients. Twenty smoker male patients aged (18-72) years with multiple teeth extraction were participated in this clinical research. They underwent trans alveolar extraction of 40 teeth. The extraction sockets were divided in each patient into 2 groups: the study group in which extraction sockets were treated with PRF and the control group: in which extraction sockets left to heal naturally without PRF. Platelet-rich fibrin enhanced soft tissue healing and reduced inflammatory process within the study group compared with control group as the 2-tailed P value equaled 0.0035 which was very statistically significant. Pain level according to visual analog scale in control group had average of (1.8), while in the study group had average of (0.65) and the P value equaled 0.1511 which was not statistically significant. Degree of epithelization was recorded by dental caliper for both groups and the 2-tailed P value equaled 0.7134 which was insignificant. The results from this study showed that PRF enhanced the quality of soft tissue healing of extraction socket among smoker patients but it did not show significant difference regarding pain reduction, dry socket prevention, and socket closure. Future clinical trials are required to clearly identify the effectiveness of PRF regarding this subject. PMID- 30277952 TI - Achondroplasia: Orocraniofacial Features and Orthodontic-Surgical Management Guidelines Proposal. AB - In this study, the authors aimed to describe orocraniofacial features and to suggest orthodontic-surgical managements in achondroplasia, based on a literature review. The authors focused on skeletal and dentoalveolar malocclusion in order to highlight the place of orthognathic surgery, based on our experience of 3 patients. Maxillary hypoplasia in achondroplasia typically results in an Angle class III malocclusion with an anterior open bite. The other orocraniofacial features include enlarged calvarium, prominent forehead and frontal bossing, midface hypoplasia, elongated lower face and saddle-shaped nose due to lack of development of the nasomaxillary complex.All our patients had a typical facial appearance but each of them had their own particularities regarding medical history and severity of the dentoskeletal dysmorphosis. Two of them were successfully treated by orthognathic surgery; the other declined surgical treatment and underwent orthopedic treatment only (anchorage plates). The treatment failure of this 3rd patient raises the question of the efficiency of anchorage plates in achondroplasia. In the light of the literature and our results, the authors conclude the need for personalized management based on age, medical history, severity of the dentoskeletal dysmorphosis, functional and/or esthetic disorders, and the patient's needs and requests. In any patient, orthodontic management should be initiated at an early age, and orthognathic surgery modalities should be personalized and adapted to each situation. PMID- 30277953 TI - Huge Extra Cranial Arteriovenous Malformation Presenting as Fluctuant Mass in Scalp. AB - Arteriovenous malformation (AVM) of the scalp is an uncommon condition. Clinical manifestations usually include local pain, pulsatile mass, headache, numbness, tinnitus; and less frequently, necrosis and hemorrhage. This study discusses and illustrates an unusual case of AVM in scalp with its radiologic appearance and clinical features. PMID- 30277954 TI - Jug Handle Tributary of Internal Jugular Vein: A Potentially Dangerous Venous Variation. AB - Variations of internal jugular vein (IJV) are rare and are surgically important. Here an unreported variation of IJV is presented. Right IJV had an unusual vein joining it in the form of a "jug handle." This vein arose from the junction of IJV and common facial vein (CFV), coursed down for 3 cm and joined IJV again. The CFV was dilated. Knowledge of this rare case could be useful to craniofacial surgeons, radiologists, and anesthesiologists. It might decrease the chances of iatrogenic bleeding during head and neck surgeries and radiologic procedures. PMID- 30277955 TI - Intra- and Postoperative Complications of Le Fort I Maxillary Osteotomy. AB - BACKGROUND: The Le Fort I maxillary osteotomy is a versatile and simple procedure, which has gained popularity nowadays, to correct a wide range of malocclusion and maxillofacial deformities. This procedure is often associated with significant but rare postoperative complications. The aim of this study was to evaluate the types and frequencies of intra- and perioperative complications related to Le Fort I osteotomies in noncleft Iranian patients. MATERIALS AND METHODS: In this prospective study, all the healthy systemic patients, (ASA I, II) with the age range of 18 to 30 years from both genders, who had the skeletal class II or III deformities and required only isolated 1-piece maxillary Le Fort I osteotomy, were included in this study. These patients had no craniofacial cleft history and were candidates for orthognathic surgery in Maxillofacial Surgery Department of Qaem Hospital of Mashhad (Iran), 2015 to 2017. All of the operations were carried out or supervised by a single surgeon and anesthesiologist using the same protocol. The patients were monitored for occurrence of intra- or postoperative complications till 6 months. The t-test, Chi-squared test, and Fisher exact test were performed for data analysis using SPSS version 16 (SPSS Inc, Chicago, IL). RESULTS: In the present study, a total of 114 consecutive patients with the average age of 22 +/- 5 years from October 2015 to November 2017 were recruited. About 77 (67.54%) patients were presented skeletal class III deformity and 37 (32.46%) were class II. The most prevalent maxillary movement after Le Fort I osteotomy was identified to be isolated maxillary advancement in 51 (44.75%) patients. Only 10 (8.77%) of all 114 patients confronted surgical complications. Hemorrhagic complication (arterial bleeding from descending palatine artery and epistaxis) and anatomic complications (septal deviation and bad fracture) would be the most prevalent complications with the frequency of 5.25% and 3.5% in total. Maxillary setback with impaction presented the highest rate (36.4%) of complications compared to other maxillary movement types. On balance, there was a significant association between Le Fort I surgery complications and maxillary movement types in our research (P = 0.002). CONCLUSION: The rate of intra- and postoperative complications following Le Fort I osteotomy for healthy noncleft adults in our center was low. Therefore, it can be concluded that this technique is safe and reliable. The maxillofacial surgeon should pay more attention for prevention or even management of the risk of intra- and perioperative complications in patients with anatomic irregularities (previous craniofacial cleft or trauma history) and those who required maxillary setback concomitant with impaction movements. PMID- 30277956 TI - Three Dimensional Printed Bone Implants in the Clinic. AB - Implants are being continuously developed to achieve personalized therapy. With the advent of 3-dimensional (3D) printing, it is becoming possible to produce customized precisely fitting implants that can be derived from 3D images fed into 3D printers. In addition, it is possible to combine various materials, such as ceramics, to render these constructs osteoconductive or growth factors to make them osteoinductive. Constructs can be seeded with cells to engineer bone tissue. Alternatively, it is possible to load cells into the biomaterial to form so called bioink and print them together to from 3D bioprinted constructs that are characterized by having more homogenous cell distribution in their matrix. To date, 3D printing was applied in the clinic mostly for surgical training and for planning of surgery, with limited use in producing 3D implants for clinical application. Few examples exist so far, which include mostly the 3D printed implants applied in maxillofacial surgery and in orthopedic surgery, which are discussed in this report. Wider clinical application of 3D printing will help the adoption of 3D printers as essential tools in the clinics in future and thus, contribute to realization of personalized medicine.

AB - The determinants of health inequities between Indigenous and non-Indigenous populations include factors amenable to medical education's influence, for example, the competence of the medical workforce to provide effective and equitable care to Indigenous populations. Medical education institutions have an important role to play in eliminating these inequities. However, there is evidence that medical education is not adequately fulfilling this role, and in fact may be complicit in perpetuating inequities.This article seeks to examine the factors underpinning medical education's role in Indigenous health inequity, in order to inform interventions to address these factors. The authors developed a consensus statement that synthesizes evidence from research, evaluation, and the collective experience of an international research collaboration including experts in Indigenous medical education. The statement describes foundational processes that limit Indigenous health development in medical education and articulates key principles that can be applied at multiple levels to advance Indigenous health equity.The authors recognize colonization, racism, and privilege as fundamental determinants of Indigenous health that are also deeply embedded in Western medical education. In order to contribute effectively to Indigenous health development, medical education institutions must engage in decolonization processes and address racism and privilege at curricular and institutional levels. Indigenous health curricula must be formalized and comprehensive, and must be consistently reinforced in all educational environments. Institutions' responsibilities extend to advocacy for health system and broader societal reform to reduce and eliminate health inequities. These activities must be adequately resourced and underpinned by investment in infrastructure and Indigenous leadership.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30277959 TI - Sentinel Emotional Events: The Nature, Triggers, and Effects of Shame Experiences in Medical Residents. AB - PURPOSE: This study explores an under-investigated topic, how medical residents experience shame within clinical learning environments, by asking residents to reflect on (1) the nature of their shame experiences; (2) the events that triggered, and factors that contributed to, those shame experiences; and (3) the perceived effects of those shame experiences. METHOD: In this hermeneutic phenomenology study, the authors recruited 12 (self-nominated) residents from an internal medicine residency at a large teaching hospital in the United States. Data collection from each participant included (1) a written reflection about an experience during medical training in which the participant felt 'flawed, deficient, or unworthy,' and (2) a semi-structured interview that explored the participant's shame experience(s) in depth. The data were analyzed according to the hermeneutic traditions, producing rich descriptions about participants' shame experiences. RESULTS: Participants' shame experiences ranged from debilitating emotional and physical reactions to more insidious, fleeting reactions. Participants reported shame triggers relating to patient care, learning processes, and personal goals; numerous factors contributed to their shame experiences. The effects of shame reactions included social isolation, disengagement from learning, impaired wellness, unprofessional behavior, and impaired empathy. Positive effects of shame reactions included enhanced learning, increased willingness to reach out for help, and improved relationships. CONCLUSIONS: Shame reactions can be sentinel emotional events with significant physical and/or psychological effects in medical learners. This study has implications for learners, educators, and patients, and it may pave the way toward open, honest conversations about the role shame plays in medical education.Written work prepared by employees of the Federal Government as part of their official duties is, under the U.S. Copyright Act, a "work of the United States Government" for which copyright protection under Title 17 of the United States Code is not available.

PMID- 30277960 TI - Affirmative Action and Holistic Review in Medical School Admissions: Where We Have Been And Where We Are Going. AB - Current challenges to affirmative action policies are cause for concern for medical schools that employ holistic admissions processes, which consider an applicant's race, ethnicity, gender, status as a first-generation college student, educational and socioeconomic status, geographical location, past experiences with minority and underserved populations, social capital, and immigration status. Students from minority and underserved communities bring with them experiences and perspectives that may enhance the care they provide to underserved patients, improving patient outcomes. Student body diversity is also associated with increases in students' academic performance, retention, community engagement, cooperation, and openness to different ideas and perspectives, and institutions that foster diversity tend to be nurturing places where all students and faculty can thrive.The use of race as a factor in admissions has been upheld in three Supreme Court decisions. Yet, the Supreme Court likely will rule again on this issue. In the meantime, medical schools must maintain or increase support for science, technology, engineering, and math academic enrichment programs at all levels, stay informed about their institutional climate, and support a holistic admissions process that considers race and socioeconomic status. Doing so will help disadvantaged students overcome the intergenerational barriers created by race, ethnicity, and poverty and help grow a culturally-competent health care workforce, which is essential to improving individual and population health and narrowing racial and ethnic health disparities.

PMID- 30277962 TI - Physical Therapy Management of Congenital Muscular Torticollis: A 2018 Evidence Based Clinical Practice Guideline From the APTA Academy of Pediatric Physical Therapy. AB - BACKGROUND: Congenital muscular torticollis (CMT) is a postural deformity evident shortly after birth, typically characterized by lateral flexion/side bending of the head to one side and cervical rotation/head turning to the opposite side due to unilateral shortening of the sternocleidomastoid muscle; it may be accompanied by other neurological or musculoskeletal conditions. Infants with CMT should be referred to physical therapists to treat these postural asymmetries as soon as they are identified. PURPOSE: This update of the 2013 CMT clinical practice guideline (CPG) informs clinicians and families as to whom to monitor, treat, and/or refer and when and what to treat. It links 17 action statements with explicit levels of critically appraised evidence and expert opinion with recommendations on implementation of the CMT CPG into practice. RESULTS/CONCLUSIONS: The CPG addresses the following: education for prevention; referral; screening; examination and evaluation; prognosis; first-choice and supplemental interventions; consultation; discontinuation from direct intervention; reassessment and discharge; implementation and compliance audits; and research recommendations. Flow sheets for referral paths and classification of CMT severity have been updated.

AB - PURPOSE: This study presents survey responses of pediatric physical therapists' use and alteration of standardized assessments of motor function in children aged 2 to 10 years. METHODS: Electronic and paper surveys were distributed to practicing physical therapists through the APTA Academy of Pediatric Physical Therapy electronic newsletter and 2 national conferences. Data were analyzed by response frequencies, qualitative responses, and chi(2) analyses for demographic characteristics. RESULTS: A total of 497 pediatric physical therapists responded. Most (93%) reported using standardized assessments, with the majority (84%) reporting the normative scores. Almost all respondents (94%) also reported that they at least occasionally modify assessments. CONCLUSION: Standardized assessments are used by most therapists, but the high use of modifications during testing is concerning. Survey reports from therapists indicate a disconnect between standardized assessments and the needs of the child, leaving clinicians working to report required scores while maintaining validity of testing procedures.

AB - PURPOSE: The purpose of this study was to investigate the physical activity levels in children with congenital myotonic dystrophy (CDM), and to examine whether patient clinical and functional characteristics correlated to physical activity. METHODS: Twenty-five children with CDM were assessed on functional measures, clinical measures, and physical activity levels. RESULTS: Results support that children with CDM spend the majority of their time inactive. There was a negative correlation between inactivity and cytosine-thymine-guanine repeats, suggesting increased inactivity with increased CDM severity. Age, body mass index, and lean muscle mass may be factors influencing activity levels. CONCLUSIONS: Children in this study received one-third the recommended steps per day. The number of steps per day is not correlated with clinical measures. PMID- 30277970 TI - Commentary on "Stepping Activity in Children With Congenital Myotonic Dystrophy".

AB - PURPOSE: To assess a whole-body vibration (WBV) intervention for children after cancer treatment. METHODS: Eleven children after inpatient anticancer therapy participated in a 12-week supervised WBV intervention, which consisted of one 9- to 13-minute WBV session per week, with 5 to 9 minutes' overall vibration time. Feasibility was defined as the ability to participate in WBV training without reporting adverse events. The number of offered and completed training sessions, program acceptance, and measures of function were assessed. RESULTS: Nine participants completed the WBV intervention without any WBV-related adverse events. The adherence rate was 87.96%. Only minor side effects were reported and there was general program acceptance. We found indications that WBV has positive effects on knee extensor strength and active ankle dorsiflexion range of motion. CONCLUSIONS: WBV was feasible, safe, and well received among children after inpatient anticancer therapy. No health deteriorations were observed. Positive effects need to be confirmed in future trials.

PMID- 30277973 TI - Walking and Fitness Improvements in a Child With Diplegic Cerebral Palsy Following Motor-Assisted Elliptical Intervention. AB - PURPOSE: To quantify effects of motor-assisted elliptical (Intelligently Controlled Assistive Rehabilitation Elliptical [ICARE]) training on walking and fitness of a child with cerebral palsy (CP). KEY POINTS: A 12-year-old boy with walking limitations due to spastic diplegic CP (Gross Motor Function Classification System II) participated in 24 sessions of primarily moderate- to vigorous-intensity ICARE exercise. Fitness improvements were evidenced clinically across sessions by the child's capacity to train for longer periods, at faster speeds, and while overriding motor's assistance. Postintervention, the child walked faster with greater stability and endurance and more rapidly completed the modified Time Up and Go test. CONCLUSION: The child's fitness and gait improved following engagement in a moderate- to vigorous-intensity gait-like exercise intervention. RECOMMENDATIONS FOR CLINICAL PRACTICE: Integration of moderate- to vigorous-intensity motor-assisted elliptical training can promote simultaneous gains in fitness and function for children with CP.

AB - OBJECTIVES: To determine whether fracture of the lateral process (LP) elevates the risk of development of radiographic subtalar arthrosis in patients with talar body and neck fractures. DESIGN: Retrospective review. SETTING: Level 1 academic trauma center. PATIENTS/PARTICIPANTS: Eighty-two patients with 43 talar neck and 43 talar body fractures treated over a 5-year period. INTERVENTION: Preoperative and postoperative radiographs were evaluated for fracture of the LP of the talus and subsequent development of radiographic subtalar arthritis. MAIN OUTCOME MEASUREMENTS: Radiographic evidence of subtalar arthritis. RESULTS: Seventy-six percent of talar neck fractures with involvement of the LP went on to develop radiographic evidence of subtalar arthrosis compared with 36% of talar neck fractures without LP involvement (P = 0.035). Thirty of the fractures involving the LP had a separate LP fragment. Fifteen of the 30 fractures with a separate LP fragment that underwent reduction and fixation developed radiographic evidence of subtalar arthrosis, whereas all 13 fractures with an independent LP fragment that did not have fixation of the LP went on to develop radiographic evidence of subtalar arthritis (P = 0.001). Comminution of the inferior talar articular surface was found to significantly increase the risk of radiographic subtalar arthritis in both talar body and talar neck fractures (P = 0.0003). An anatomic reduction of both talar neck and body fractures was found to be associated with a lower incidence of radiographic subtalar arthritis (P = 0.00001). CONCLUSION: Comminution of the inferior articular surface of the talus elevates the risk of subtalar arthritis in patients with both talar neck and body fractures. Fracture of the LP is a marker for injury to the talar inferior articular surface and increases the risk for the radiographic finding of subtalar arthritis in patients with talar neck fractures.

PMID- 30277977 TI - Risk Factors for Conversion to Total Hip Arthroplasty After Acetabular Fractures Involving the Posterior Wall. AB - OBJECTIVES: Identify risk factors for early conversion to total hip arthroplasty (THA) in an effort to aid in counseling patients and selecting the optimal treatment for patients who sustain a fracture involving the posterior wall of the acetabulum. DESIGN: Retrospective cohort analysis. SETTING: Level I trauma center. PATIENTS: Patients with acetabular fractures involving the posterior wall managed with open reduction internal fixation at least 4 years out from surgery. INTERVENTION: Preoperative and postoperative computed tomography scans were reviewed for injury characteristics and reduction quality. Participants were contacted by telephone to document reoperations and functional outcomes including the SF-8 and modified Merle d'Aubigne Hip Scale. MAIN OUTCOME MEASURE: Conversion to THA. RESULTS: The overall rate of conversion to THA was 5% at 2 years, 14% at 5 years, and 17% at 9 years. Presence of 5 specific radiographic features was associated with a 50% rate of conversion to THA in contrast to 11% if 4 or less features were present. Among cases with less than 1 mm of diastasis/step-off on postoperative computed tomography scan, there were no THA conversions, 10% conversion for 1-4 mm, and 54% if 4 mm or more of malreduction. There was no difference in SF-8 or modified Merle d'Aubigne scores comparing patients who underwent THA and those who did not. CONCLUSIONS: Acetabular fractures with posterior wall involvement are associated with a significantly higher rate of conversion to THA if reduction is not near-anatomic. A combination of clinical/radiographic findings is associated with poorer reductions and higher rate of conversion to THA. LEVEL OF EVIDENCE: Prognostic Level IV.

We aimed to compare the pooled rate of adverse events based on the country of study origin, acute versus delayed fracture fixation, and length of follow up. METHODS: We searched PubMed/MEDLINE/Cochrane databases from 2000-2016 for English language studies. There was substantial heterogeneity among included studies. Therefore, we employed sub-group analysis of varying adverse events and removal of potential outlier studies based on the 'remove one' sensitivity analysis, to address the heterogeneity across studies. A funnel plot was drawn and inspected visually to assess publication bias. We reported pooled complication rates for each adverse event with 95% prediction interval (PI). RESULTS: There were 14 studies with 47,169 cases across 58 different LMICs. The average age was 33 +/- 14 years, with 83% male and 17% female. Sixty percent of SIGN nails utilized in these 14 studies were used in femur fracture fixation, 38% in tibial shaft fractures, and the remaining 2% for humeral shaft fractures. Approximately 23% of patients had follow-up data recorded. All studies that measured clinical outcome indicated that >90% achieved full weight-bearing status, favorable range of motion (knee range of motion >90 degrees according to the SIGN database), and radiographic or clinical union depending on the specific variable(s) measured in each study. The overall complication rate was 5.2% (4.4% 6.4%). Malalignment (>5 degrees angulation in any plane) was the most common complication (7.6%), followed by delayed/non-union (6.9%), infection (5.9%), and hardware failure, (3.2%). CONCLUSION: Overall, the use of SIGN nails in fixing femoral, tibial, and humeral shaft fractures demonstrates good results with a high rate of return to full weight-bearing and radiographic/clinical union. The most common complications when using the SIGN nail are malalignment, delayed/non union, infection and hardware failure. LEVEL OF EVIDENCE: Level-IV meta-analysis. PMID- 30277979 TI - Impact of Direct Oral Anticoagulants (DOACs) in Patients with Hip Fractures. AB - OBJECTIVE: To assess the impact of direct oral anticoagulant (DOAC) intake compared to Coumadin (COU) in patients suffering hip fractures (HF). DESIGN: Retrospective cohort analysis SETTING:: Level 1 Trauma Center INTERVENTION:: Timing of surgical hip fixation. PATIENTS: Three-hundred twenty patients >= 65 years of age with isolated HF were enrolled into the study: 207 (64.7%) without any antithrombotic therapy (no-ATT), 59 (18.4%) on COU and 54 (16.9%) on DOACs. MAIN OUTCOME MEASUREMENTS: Time to surgery, blood loss, mortality, hospital length of stay, red blood cell transfusion, use of reversal agents and Charlson Comorbidity Index. RESULTS: Patients on COU and DOACs had a higher Charlson Comorbidity Index compared to the no-ATT group (p < 0.0001). Despite the fact that significantly more patients received reversal agents in the COU group compared to DOAC medication (p<0.0001), percentage of transfused patients were similar (54.2% vs. 53.7%). Time to surgery was significantly shorter in the no ATT group when compared with DOAC patients (12 to 29.5 hours respectively). No difference in postoperative hemorrhage, ICU length of stay and mortality was observed between groups. CONCLUSIONS: DOAC medication in HF patients caused long elapse time until surgical repair. We found no evidence of higher bleeding rates in HF patients on DOACs compared to COUs. Earlier HF fixation might be indicated in DOAC patients.

PMID- 30277980 TI - Foot Function After Surgically Treated Intraarticular Calcaneal Fractures: Correlation of Clinical and Pedobarographic Results of 65 Patients Followed for 8 Years. AB - OBJECTIVES: To correlate functional deficits after surgical treatment of displaced intraarticular calcaneal fractures (DIACFs) as measured through dynamic pedobarography with clinical and radiographic long-term results. DESIGN: Retrospective single-center study. SETTING: Level 1 trauma center. PATIENTS: Sixty-five patients with unilateral DIACFs, reexamined at an average of 8.1 years after surgery. INTERVENTION: Internal fixation of DIACF with lateral plate or percutaneous screws. MAIN OUTCOME MEASUREMENTS: Dynamic pedobarography, AOFAS, Zwipp, SF-36 scores, Foot Function Index, Bohler angle, and articular congruity. RESULTS: When compared with the uninjured side, pedobarography of the operated foot revealed a significantly increased contact area of the hindfoot and midfoot, with a decreased contact area under first/second metatarsal (MT) and first/second toe after DIACF. Maximum pressure and pressure time integral were significantly increased at the midfoot and lateral MT with a decrease under the hindfoot and first to second MT/toe. Midfoot pressure time integral correlated with the range of plantarflexion. Fracture classification correlated with MT 1 contact time. Hindfoot and MT contact times were negatively correlated with Bohler angle. Patients with the smallest side-to-side differences in pedobarogaphy had overall highest scores and significantly greater ankle/hindfoot range of motion at follow up. CONCLUSIONS: Significant correlations were found between clinical and pedobarographic results. Increased contact areas and time at the midfoot indicating a lateral load shift correlated with inferior outcome and decreased subtalar motion. These results support the importance of reconstruction of the subtalar joint and overall bony morphology of the calcaneus with preservation of subtalar motion as necessary for global foot function.

PMID- 30277981 TI - Decreased Lean Psoas Cross-sectional Area is Associated with Increased One-year All-cause Mortality in Male Elderly Orthopaedic Trauma Patients. AB - OBJECTIVES: To investigate the association between lean psoas Cross-sectional Area (CSA) and one-year all-cause mortality in elderly patients sustaining pelvic and long bone fractures. DESIGN: Retrospective cohort SETTING:: Level one center PATIENTS:: Elderly trauma patients admitted from 2007-2014. METHODS: We reviewed demographic and clinical data, injury mechanism, fracture OTA/AO classification, and mortality. Axial Computed Tomography (CT) images were used to measure lean psoas CSA at the L3-L4 disk space. Cox proportional hazard regression analysis was used to estimate one-year mortality association with psoas CSA in crude and adjusted for age, BMI, ISS, medical comorbidities and discharge destination in total population and stratified by gender. MAIN OUTCOME MEASUREMENT: One-year all cause mortality defined as death within 12 months from date of hospitalization. RESULTS: 558 patients (54% female, 46% male) were analyzed. The pelvis was most commonly fractured (37.81%). A statistically significant association was observed between decreased lean psoas CSA and one-year mortality in total population [Hazard Ratio (HR)= 0.93 (95% Confidence Interval (CI)= 0.90-0.96), p<0.0001]. Stratification by gender revealed a statistically significant mortality HR in male patients [HR= 0.89 (95% CI= 0.84-0.96), p= 0.002]. We did not find a statistically significant mortality HR in female patients [HR= 0.95 (95% CI= 0.89 1.01), p= 0.103]. CONCLUSIONS: In this cohort of elderly orthopaedic trauma patients, decreased lean psoas CSA was associated with increased one-year all cause mortality in total population and males. Further investigation of the association of sarcopenia with mortality in the elderly is warranted. LEVEL OF EVIDENCE: Level III prognostic. PMID- 30277982 TI - Nail Plate Combination (NPC) Technique for Native and Periprosthetic Distal Femur Fractures: A Technical Trick. AB - SUMMARY: In the elderly, low energy distal femur fractures (native or periprosthetic) can be devastating injuries, carrying high rates of morbidity and mortality, comparable to the hip fracture population. Poor, osteoporotic bone quality facilitates fracture in a vulnerable anatomic region and as a result, operative fixation can be challenging. With goals of early mobilization to reduce subsequent complication risk, employing the nail plate combination (NPC) technique can offer stable, balanced fixation allowing for immediate weight bearing and early mobilization. We outline the rationale, technical steps, and early clinical outcomes following NPC in the treatment of osteoporotic distal femur (native or periprosthetic) fractures. PMID- 30277983 TI - Self-Reported Recovery Likelihood Predicts Higher Physician Ratings following Orthopaedic Surgery. AB - OBJECTIVES: What are the differences between elective and trauma patient satisfaction and do patient and diagnosis factors predict physician scores? DESIGN: Prospective cohort study SETTING:: Urban Level 1 Trauma center PATIENTS/PARTICIPANTS:: 323 trauma patients and 433 elective orthopaedic patients treated at our center by the same surgeons INTERVENTION:: Trauma patients treated surgery for one or more fractures; elective patients treated with hip, knee, or shoulder arthroplasty, or rotator cuff repair. MAIN OUTCOME MEASUREMENTS: Telephone survey regarding patient experience and satisfaction with their care. The survey included questions from Hospital Consumer Assessment of Healthcare Providers and Systems surveys (HCAHPS), and responses were rated on a 1-5 point Likert scale (5 best). RESULTS: Elective surgery patients had mean age of 56.4 years, and trauma patients were mean 50.3 years of age. Trauma patients rated their likelihood to make a full recovery lower than elective patients, (Median, Interquartile Range), 5.0(1.0) vs. 4.0(2.0) (p<0.001). Following multivariate binary logistic regression, patients who rated the hospital higher (>=4 versus <=3), were more likely OR=10.0, 95% CI [6.4, 15.8] to score physicians better. Similarly, patients who scored their overall likelihood of recovering >=4 compared to <=3, were more likely OR=3.6, 95% CI [2.9, 5.6] to rate their physicians more positively. CONCLUSIONS: Patient perceptions including their likelihood to make a full recovery and their overall impression of the hospital predicted higher physician scores. We conclude that these physician scores are subject to patient perception biases and are not independent of the overall care experience. We recommend HCAHPS and physician ratings websites include internal controls, such as the patient perception of overall likelihood to recover, to aide in interpreting survey results.

AB - Supracondylar femur fractures represent a challenging and common injury treated by many orthopedic surgeons. An array of surgical fixation options has been developed to help the treating surgeon restore normal anatomic alignment of these fractures, and lateral precontoured condylar femoral locking plates have become a common implant for most surgeons in treating these fractures. Though these precontoured plates provide significant benefit to the treating physician in regards to gaining appropriate bony fixation, common technical errors that may lead to malalignment when utilizing these plates have been described. Avoiding these errors will help improve patient outcomes. Here, we describe a novel, inexpensive, and universally available technique that may aid the treating surgeon in restoring coronal alignment when treating distal femur fractures. PMID- 30277985 TI - Knee pain and functional scores after intramedullary nailing of tibial shaft fractures using a suprapatellar approach. AB - OBJECTIVES: To evaluate the effects of intramedullar nailing of the tibia using a suprapatellar approach with respect to pain and function of the knee. DESIGN: Prospective clinical investigation SETTING:: Academic level I trauma center PATIENTS/PARTICIPANTS:: Twenty-one patients with tibial shaft fractures (OTA 42A B-C) with a minimum of twelve months follow up. INTERVENTION: Locked intramedullary nailing using a suprapatellar approach MAIN OUTCOME MEASUREMENTS:: Radiographic evaluation for nail position proximally, tibial shaft alignment and union, anterior knee pain using the Visual Analog Scale (VAS), and knee function evaluation using the Lysholm and SF-36 scores. Examination of intra-articular damage was performed using intraoperative patellofemoral arthroscopy before and after nail insertion. RESULTS: The mean age of the patients was 35.4+/-12.4 years (range, 18-63 years) and the mean follow-up period was 15.62+/-3.2 months (range, 12-21 months). The VAS score for anterior knee pain was a mean of 1.0+/-1.3 (range, 0-4). The SF-36 physical score was mean 45.1+/-9 and the SF-36 mental score was a mean of 51.7+/-9.9. The knee joint ROM was measured as 133.1 degrees +/-87 degrees on the affected extremity side and 134.05 degrees +/-8.4 degrees on the unaffected side. The mean Lysholm knee score was 95.76+/-4. No intra articular pathology was seen on arthroscopy after nail insertion. CONCLUSIONS: The suprapatellar approach for intramedullar nailing for tibial shaft fractures was not associated with either anterior knee pain or functional limitations of the knee in our series. PMID- 30277986 TI - Outcome Analysis of Surgical Stabilization of Rib Fractures in Trauma Patients. AB - OBJECTIVES: To compare outcomes in patients with rib fractures (RFX) who underwent surgical stabilization of rib fractures (SSRF) to those treated non operatively. DESIGN: Retrospective cohort study SETTING:: Two Level 1 Trauma Centers. Florida, USA PATIENTS:: 174 patients with multiple rib fractures divided in 2 groups: Patients with Surgically Stabilized Rib Fractures (n=87) were compared to non-operatively managed patients in the Matched Control Group (n=87). INTERVENTION: Surgical stabilization of rib fractures OUTCOME MEASUREMENTS:: Age, gender, ISS, RFX, mortality, hospital (HLOS) and ICU length of stay (ICULOS), days of mechanical ventilation (DMV), co-injuries, and time to surgery. Patients were further stratified by presence or absence of flail chest and pulmonary contusion. RESULTS: Flail chest, displaced RFX and pulmonary contusion were present significantly more often in SSRF patients compared to the MCG. Mortality was lower in SSRF group. HLOS and ICULOS were longer in SSRF group compared to the corresponding MCG patients regardless of timing to surgery (p<0.01 for all). SSRF patients with flail chest had comparable HLOS, ICULOS and DMV to MCG patients with flail chest (p>0.3 for all). SSRF patients without flail chest had significantly longer HLOS and ICULOS than MCG patients without flail chest (p<0.001 for both). Presence of pulmonary contusion did not affect lengths of stay. CONCLUSIONS: SSRF patients had reduced mortality compared to non operatively managed patients. HLOS, ICULOS and DMV were longer in SSRF patients than in MCG. When flail chest was present, lengths of stay were comparable. Pulmonary contusion did not appear to affect the surgical outcome. LEVEL OF EVIDENCE: Therapeutic Level III.

PMID- 30277987 TI - A Prospective Study of the Effectiveness of Paroxetine on the Onset of Posttraumatic Stress Disorder, Depression, and Health and Functional Outcomes After Trauma. AB - OBJECTIVES: To determine whether the administration of medication for posttraumatic stress disorder (PTSD) to injured trauma survivors prevents or mitigates PTSD. DESIGN: Double-blinded, placebo-controlled. SETTING: Level I trauma center. PATIENTS: One hundred and twenty patients admitted for traumatic orthopedic injury. INTERVENTION: Either paroxetine or placebo starting 2 weeks postinjury. MAIN OUTCOME MEASUREMENTS: PTSD symptoms were measured with the PTSD Checklist for DSM-IV. The Quick Inventory of Depressive Symptomatology (QIDS) assessed the presence and severity of DSM-IV-TR major depressive symptoms. The SF 36 measured post-injury quality of life and social functioning. The Short Musculoskeletal Functional Assessment (SMFA) rated post-injury musculoskeletal function. RESULTS: The paroxetine group did not differ from the placebo group in proportions with PTSD as assessed at the 6-month or 12-month follow up or in proportions with major depression symptoms since the injury as assessed at the 3 month follow up. The groups also did not differ at the 8-week follow up in amount of change from baseline in QIDS scores. The paroxetine group had a marginally greater increase from baseline in SF-36 functioning score at the 12-month follow up as compared with the placebo group and a marginally greater reduction from baseline in SMFA musculoskeletal functioning at the 12-month follow up as compared with the placebo group. CONCLUSIONS: These results suggest the potential for psychotropic medication to prevent or reduce posttraumatic stress symptoms and to improve the function and health of trauma patients. Further research is needed to confirm paroxetine's use for this purpose. LEVEL OF EVIDENCE: Therapeutic Level II. PMID- 30277989 TI - Knee Stiffness After Tibial Plateau Fractures: Predictors and Outcomes (OTA-41). AB - OBJECTIVES: What patient characteristics and injury factors predict decreased knee range of motion (ROM) after operative management of tibial plateau fractures? DESIGN: Prospective cohort study. SETTING: Academic medical center. PATIENTS: Over 11 years, tibial plateau fractures at a single academic institution were prospectively followed. A total of 266 patients were included in this study. INTERVENTION: Surgical repair of tibial plateau fractures and secondary interventions due to arthrofibrosis. MAIN OUTCOME MEASURE: Clinical outcomes were evaluated using the Short Musculoskeletal Function Assessment and ROM at 3-month, 6-month, and long-term follow-up. Secondary outcomes were considered as the need for a subsequent procedure due to arthrofibrosis. RESULTS: At 3-month follow-up, the mean ROM was 113 degrees. By long-term follow-up (mean = 17 months), the mean ROM improved to 125 degrees. Independent predictors of decreased knee ROM were the following: at 3-month follow-up, open fractures (P = 0.047), application of a knee-spanning external fixator (P = 0.026), orthopaedic polytrauma (P = 0.003), and tibial spine involvement (P = 0.043); and at long term follow-up, nonwhite ethnicity (P = 0.003), increasing age (P = 0.003), and a deep infection (P = 0.002). Ten patients (3.7%) required a secondary procedure for arthrofibrosis. There was a significant improvement in the knee ROM (P < 0.001) and functional outcomes (P = 0.004) following the intervention. CONCLUSIONS: At long-term follow-up, independent predictors of decreased knee ROM were nonwhite ethnicity, increasing age, and sustaining a postoperative complication of a deep infection. Secondary interventions were reliable treatments for arthrofibrosis. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence. PMID- 30277990 TI - The Incidence of Posterior Malleolar Involvement in Distal Spiral Tibia Fractures: Is it Higher than We Think? AB - OBJECTIVES: To investigate the incidence of concomitant posterior malleolar fractures (PMFs) in operative, distal-third, spiral tibia fractures. DESIGN: Prospective protocol with retrospective review of data. SETTING: Single, Level 1 trauma center. PATIENTS/PARTICIPANTS: One hundred ninety-three consecutive, skeletally mature patients with operatively treated fractures of the distal third, tibial shaft and metaphysis. Pilon fractures were excluded. INTERVENTION: Computed tomography (CT) scans were obtained in all distal-third, spiral fractures of the tibia to determine fracture morphology and presence of a PMF. MAIN OUTCOME MEASUREMENTS: The incidence of concurrent PMFs in operative spiral fractures of the distal tibia. RESULTS: Twenty-six distal-third, spiral fractures were identified with an ipsilateral PMF diagnosed in 92.3% of cases (24 cases). PMFs were over 25 times more likely to occur in distal-third, spiral fractures when compared with other distal-third fracture patterns (relative risk = 25.7, 95% confidence interval, 11.6-56.8). PMFs were treated with supplemental fixation in 23/24 (95.8%) cases. CONCLUSIONS: There is a high incidence of concomitant, ipsilateral fractures of the posterior malleolus in patients presenting with operative distal-third, spiral fractures of the tibia. A preoperative ankle computed tomography should be strongly considered in all cases with this specific fracture morphology. LEVEL OF EVIDENCE: Diagnostic Level III.

PMID- 30277991 TI - Reverse shoulder arthroplasty in acute fractures of the proximal humerus: Does tuberosity healing improve clinical outcomes? AB - OBJECTIVE: The study aimed to evaluate the clinical outcomes of reverse shoulder arthroplasty (RSA) in elderly patients with proximal humeral fractures and assess the role of tuberosity healing on the outcome. DESIGN: Case series SETTING:: Multicentre clinical study of level-2 trauma centres PATIENTS/PARTICIPANTS:: We included 81 patients with a mean age of 78.5 +/- 6.5 years (range, 58.5-90.9 years) and a non-reconstructable proximal humeral fracture. INTERVENTION: Modular reverse fracture shoulder arthroplasty. MAIN OUTCOME MEASUREMENTS: We determined range of motion, Constant score (CS), and the American Shoulder and Elbow Surgeons (ASES) Shoulder Score as clinical outcomes and evaluated tuberosity healing at six weeks, six months, one year, and two years. RESULTS: Tuberosities healed in most patients; 37 patients had completely healed tuberosities and 33 patients had partially healed tuberosities, while 11 patients had unhealed tuberosities. However, no significant differences were found in the functional outcomes among the three groups (p > 0.05). CONCLUSIONS: Our results with a modular reverse prosthesis confirmed similar CSs, ASES Shoulder Scores, and tuberosity healing rates as reported in the current clinical evidence for RSA. We could not confirm that tuberosity healing improved functional outcomes; however, it should be noted that tuberosity healing was assessed using standard radiographs. Nevertheless, our study strengthens the consensus that RSA can be recommended for well-selected elderly patients with complex displaced proximal humeral fractures.

AB - BACKGROUND: The opioid epidemic in the United States has placed increased pressure on physicians to engage in responsible opioid prescribing practices. However, surgeons currently have little information to guide their postoperative prescription decision-making. The purpose of this study was to assess opioid consumption after knee arthroscopy and identify preoperative factors that may predict higher opioid usage. METHODS: A prospective observational study of 221 patients was conducted in patients undergoing outpatient knee arthroscopy for meniscal repair, partial meniscectomy, debridement, chondroplasty, or loose body removal. Participants recorded their daily opioid consumption in a postoperative pain diary. Total opioid consumption was calculated from counts of remaining pills at the 2-week and 6-week postoperative office visits. Variables, including age, sex, body mass index, smoking status, alcohol consumption, preoperative pain severity and duration, preoperative opioid usage, Patient-Reported Outcomes Measurement Information System (PROMIS) scores, and the Connor-Davidson Resilience Scale, were evaluated for an association with opioid consumption. RESULTS: Total opioid consumption ranged from 0 to 188 pills, with a median of 7 pills (hydrocodone 5-mg equivalents). Forty-six percent of patients took <=5 pills, 59% took <=10 pills, and 81% took <=20 pills. Fifty-six percent of patients had discontinued opioid usage by the third postoperative day. Eighty eight percent of patients had surplus opioid medication at the time of the final follow-up. Patients undergoing meniscal repair, smokers, and those taking preoperative opioids were significantly more likely to take >=20 pills (p < 0.05). CONCLUSIONS: The median number of pills taken after knee arthroscopy is 7, with the majority of patients consuming <=20 pills. Meniscal repair, smoking, and preoperative opioid usage were associated with higher postoperative opioid consumption. LEVEL OF EVIDENCE: Prognostic Level IV.

AB - BACKGROUND: High friction moments in hip implants contribute to the aseptic loosening of cementless cups, of which there are approximately 100,000 cases per year; sustained joint loading may cause such high moments. The most "critical" physical activities associated with sustained joint loading were identified in this study. METHODS: Friction moments in the cup were telemetrically measured about 33,000 times in the endoprostheses of 9 subjects during >1,400 different activities. The highest moments were compared with the cup's fixation stability limit of approximately 4 Nm. RESULTS: A total of 124 different activities caused friction moments meeting or exceeding the critical limit, with the highest value of 11.5 Nm. Most involved sustained high contact forces before or during the activity. The highest peak moments (6.3 to 11.5 Nm) occurred when moving the contralateral leg during 1-legged stance, during breaststroke swimming, muscle stretching, 2-legged stance with muscle contraction, and during static 1-legged stance. The median moments were highest (3.4 to 3.9 Nm) for unstable 1-legged stance, whole-body vibration training, 2-legged stance with an unexpected push at the upper body, 1-legged stance while exercising the contralateral leg, and running after 2-legged stance. CONCLUSIONS: Frequent unloading plus simultaneous movement of the joint are required to maintain good joint lubrication and keep the friction moments low. Frequent, sustained high loads before or during an activity may cause or contribute to aseptic cup loosening. During the first months after hip arthroplasty, such activities should be avoided or reduced as much as possible. This especially applies during postoperative physiotherapy. Whether these guidelines also apply for subjects with knee implants or arthrotic hip or knee joints requires additional investigation. CLINICAL RELEVANCE: The risk of aseptic cup loosening may be reduced by avoiding sustained loading of hip implants without periodic joint movement. PMID- 30277994 TI - Continuous Near-Infrared Spectroscopy Demonstrates Limitations in Monitoring the Development of Acute Compartment Syndrome in Patients with Leg Injuries. AB - BACKGROUND: We recorded measurements of muscle perfusion using near-infrared spectroscopy (NIRS) and intramuscular pressure (IMP) in a study designed to develop a decision rule for predicting acute compartment syndrome (ACS). The purpose of this study was to report our experience measuring NIRS data in the context of this broader investigation and to explore factors related to variations in data capture. METHODS: One hundred and eighty-five patients with lower-leg injuries had data consisting of continuous NIRS measurement of the O2 saturation in the anterior compartment of the injured limb and the contralateral (control) limb, and continuous IMP recording in the anterior and deep posterior compartments of the injured leg as part of their participation in an institutional review board-approved multicenter trial. All monitoring was done for a prescribed period of time. For both types of data, the percentage of valid data capture was defined as the ratio of the minutes of observed data points within a physiological range to the total minutes of expected data points. Clinically useful NIRS data required simultaneous data from the injured and control limbs to calculate the ratio. Statistical tests were used to compare the 2 methods as well as factors associated with the percent of valid NIRS data capture. RESULTS: For the original cohort, clinically useful NIRS data were available a median of 9.1% of the expected time, while IMP data were captured a median of 87.6% of the expected time (p < 0.001). Excluding 46 patients who had erroneous NIRS data recorded, the median percentage was 31.6% for NIRS compared with 87.4% for IMP data (p < 0.00001). Fractures with an associated hematoma were less likely to have valid data points (odds ratio [OR], 0.53; p = 0.04). Gustilo types-I and II open fractures were more likely than Tscherne grades C0 and C1 closed fractures to have valid data points (OR, 1.97; p = 0.03). CONCLUSIONS: In this study, NIRS data were not collected reliably. In contrast, IMP measurements were collected during >85% of the expected monitoring period. These data raise questions about the utility of current NIRS data capture technology for monitoring oxygenation in patients at risk of ACS. PMID- 30277995 TI - Cost-Effectiveness of Surgical and Nonsurgical Treatments for Unicompartmental Knee Arthritis: A Markov Model. AB - BACKGROUND: There has been increased utilization of surgical options for the treatment of end-stage unicompartmental arthritis in patients at both extremes of the age spectrum. The purpose of this study was to determine how these changing paradigms affected the lifetime cost-effectiveness of total knee arthroplasty (TKA), unicompartmental knee arthroplasty (UKA), and nonsurgical treatment (NST). METHODS: Using a Markov decision analytic model, we assessed how lifetime costs and quality-adjusted life years (QALYs) vary as a function of age at the time of initial treatment (ATIT) of patients with end-stage unicompartmental knee osteoarthritis undergoing TKA, UKA, and NST. Separate models were estimated for ATITs at 5-year intervals from 40 through 90 years. Direct medical costs, QALYs, and transition probabilities were determined from the published literature. Indirect costs (lost wages, Social Security disability collections, and value of missed workdays) were calculated. Cost-effectiveness and incremental cost effectiveness ratios (ICERs) were calculated for each treatment at each ATIT. The model assumed no crossover from NST to UKA or TKA. ICERs were compared with a willingness-to-pay threshold of 50,000 U.S. dollars, and a 1-way sensitivity analysis was used to assess the robustness of ICER-based treatment decisions. Societal savings were estimated. RESULTS: In the base-case model, surgical treatments were less expensive and provided a greater number of QALYs than NST from 40 to 69 years of age. From 70 years of age and onward, surgical treatments remained cost-effective compared with NST, with ICERs remaining below the societal willingness-to-pay threshold. When surgical treatments were compared, UKA dominated TKA for all ATITs. The preferential use of UKA in all U.S. patients with unicompartmental osteoarthritis would result in an estimated lifetime societal savings of 987 million to 1.5 billion U.S. dollars per annual wave of patients undergoing treatment. CONCLUSIONS: In this preliminary assessment, recent expansion of surgical treatments into younger and older age demographics appears to be cost-effective in the setting of unicompartmental knee osteoarthritis. Our findings suggest that NST should be used sparingly in patients below the age of 70 years and UKA should be chosen over TKA in order to maximize cost-effectiveness.

PMID- 30277996 TI - Retrieval Findings of Recalled Dual-Taper Hips. AB - BACKGROUND: The recent high-profile recalls of several dual-taper hip designs pose questions regarding why those designs perform poorly. We aimed to characterize taper damage in 1 recalled design to understand failure mechanisms to inform surgeons on which patients should be considered at risk of revision and when to revise. METHODS: High-precision measurement equipment was used to characterize the metal loss from the neck-stem interface of 116 retrieved Rejuvenate femoral stems (Stryker Howmedica Osteonics) revised because of an adverse reaction to metal debris. Head-neck taper surfaces were also investigated, and clinical and laboratory data were examined. RESULTS: The neck stem junction of each implant was moderately to severely corroded and showed a characteristic wear pattern on both male and female taper surfaces. The severity of taper damage was positively correlated with time to revision (coefficient, 0.040 [95% confidence interval (CI), 0.028 to 0.051]; p < 0.0001) and with serum cobalt concentration (coefficient, 0.02 [95% CI, 0.01 to 0.02]; p < 0.0001) and serum chromium concentration (coefficient, 0.04 [95% CI, 0.009 to 0.070]; p = 0.0142). CONCLUSIONS: A forensic examination of the retrieved components that failed secondary to an adverse reaction to metal debris showed, in all cases, visible corrosion. Of the implant and patient factors investigated, we did not identify any predictors of corrosion. The severity of damage was found to increase with time; cobalt was significantly elevated over chromium. CLINICAL RELEVANCE: Surgeons should scrupulously follow and consider revision for patients with this implant design to avoid extensive tissue excision. Blood metal ion tests may aid in identifying the mechanisms of taper corrosion. PMID- 30277997 TI - Radiographic and Clinical Outcomes of Porous Titanium-Coated and Plasma-Sprayed Acetabular Shells: A Five-Year Prospective Multicenter Study. AB - BACKGROUND: New materials in cementless total hip arthroplasty are continuously introduced into clinical practice. The objective of this study was to compare the radiographic and clinical performances of acetabular shells made with porous titanium coating (PTC) and plasma-sprayed titanium (PS). METHODS: Data from a prospective multicenter study monitoring PTC and PS shells were analyzed. Three hundred and eighty patients (191 with PTC and 189 with PS) with postoperative (within 10 months after the operation) and 5-year radiographs were available for assessment of radiographic outcomes and patient-reported outcome measures (PROMs). A radiolucent distance between the cup and acetabulum of >=0.5 mm was defined as a gap if it was found on a postoperative radiograph and as a radiolucency if it was found on a later follow-up radiograph for the first time. RESULTS: Postoperative gaps were more common with the PS shell (40% versus 24%, p < 0.001). However, a higher percentage of the gaps in the PTC group persisted at 5 years (56% versus 4%, p < 0.001). At 5 years, 23% of the PTC shells had a radiolucency versus 5% of the PS shells (p < 0.001). Logistic regression revealed a 5.2-fold increase in the odds for radiolucency with the PTC shell (p < 0.001). No patient underwent revision surgery due to acetabular component loosening within the study period. A PTC shell was the only factor associated with the risk of pain in a logistic regression model (odds ratio = 2.0, p = 0.035). CONCLUSIONS: PTC shells were associated with more patient-reported pain and a higher risk of radiolucency and a persistent gap at 5 years compared with the PS shells, although these outcomes were not related to each other. The clinical relevance of the radiographic findings is unclear as no prostheses were revised because of loosening, but the findings warrant additional follow-up studies.

PMID- 30277998 TI - Osteosynthesis with Parallel Implants in the Treatment of Femoral Neck Fractures: Minimal Effect of Implant Position on Risk of Reoperation. AB - BACKGROUND: The purpose of this study was to estimate the incidence of reoperation and the effect of implant position on the risk of reoperation within 12 months following osteosynthesis with use of parallel implants for femoral neck fractures. METHODS: From cases registered in the Danish Fracture Database, 1,206 consecutive surgeries for a primary femoral neck fracture treated with use of parallel implants during the period of December 2011 to November 2015, and having available radiographs and follow-up data, were reviewed. Data included age, sex, time to surgery, fracture classification, and American Society of Anesthesiologists (ASA) score. Fracture displacement, posterior tilt, the number of implants, posterior distance, calcar distance, tip-cartilage distance, and angulation of implants were measured on pre- and postoperative radiographs. Data on secondary surgeries were collected from the Danish Civil Registration System. The effects of the included variables on the risk of reoperation were evaluated using Cox regression analysis. RESULTS: The median age was 73 years (range, 21 to 102 years); in 69% of the cases, the patient was female. Two implants were used in 997 cases and 3 implants were used in 209. In 157 cases, the patient underwent reoperation within 1 year; in 228 cases, the patient died within 1 year. The median time to reoperation was 116 days. Patients <70 years of age were more likely to undergo reoperation (18.0% compared with 9.8%) but less likely to die (7.4% compared with 26.3%) than were patients >=70 years of age. Female sex, higher ASA score, and displaced fractures were associated with increased risk of reoperation. Time to surgery was associated with increased risk of reoperation for displaced fractures only. Of the variables pertaining to the osteosynthesis, only insufficient fracture reduction, placement of the implants with an angle to the shaft of <=125 degrees , and femoral head perforation significantly increased the risk of reoperation. We found no effect of the posterior distance, the calcar distance, the tip-caput distance, or whether or not the implants were parallel. CONCLUSIONS: Insufficient reduction, varus position of the implants, and perforation of the femoral head cartilage were the only surgical factors influencing the risk of reoperation. Sufficient fracture reduction is perhaps more important than focusing on an optimal position of the implants. LEVEL OF EVIDENCE: Therapeutic Level IV.

PMID- 30277999 TI - Anterior Spinal Growth Tethering for Skeletally Immature Patients with Scoliosis: A Retrospective Look Two to Four Years Postoperatively. AB - BACKGROUND: Anterior spinal growth tethering (ASGT) has been shown to alter spinal growth with the potential to correct scoliosis while maintaining spine flexibility. The purpose of this study was to report the 2 to 4-year outcomes of ASGT in skeletally immature patients with thoracic scoliosis. METHODS: We conducted a retrospective review of patients with thoracic scoliosis who underwent ASGT with a minimum of 2 years of follow-up. Patient demographics, perioperative data, and radiographic outcomes are reported. A "successful" clinical outcome was defined as a residual curve of <35 degrees and no posterior spinal fusion indicated or performed at latest follow-up. RESULTS: Seventeen patients met the inclusion criteria. The etiology was idiopathic for 14 and syndromic for 3. The mean follow-up was 2.5 years (range, 2 to 4 years). Preoperatively, all patients were at Risser stage 0, with a mean age at surgery of 11 +/- 2 years (range, 9 to 14 years). There was an average of 6.8 +/- 0.5 vertebrae tethered per patient. The average thoracic curve magnitude was 52 degrees +/- 10 degrees (range, 40 degrees to 67 degrees ) preoperatively, 31 degrees +/- 10 degrees immediately postoperatively, 24 degrees +/- 17 degrees at 18 months postoperatively, and 27 degrees +/- 20 degrees at latest follow-up (51% correction; range, 5% to 118%). Revision surgery was performed in 7 patients: 4 tether removals due to complete correction or overcorrection, 1 lumbar tether added, 1 tether replaced due to breakage, and 1 revised to a posterior spinal fusion. In 3 additional patients, posterior spinal fusion was indicated due to progression. Eight (47%) of the patients had a suspected broken tether. Ten (59%) of the 17 were considered clinically successful. CONCLUSIONS: Despite most patients having some remaining skeletal growth at the time of review, the results of the current study demonstrate that at mid-term follow-up, ASGT showed a powerful, but variable, ability to modulate spinal growth and did so with little perioperative and early postoperative risk. Fusion was avoided for 13 of the 17 patients. The overall success rate was 59%, with a 41% revision rate. Understanding the parameters leading to success or failure will be critical in advancing a reliable definitive nonfusion treatment for progressive scoliosis in the future.

PMID- 30278000 TI - Implementing a Postoperative Opioid-Prescribing Protocol Significantly Reduces the Total Morphine Milligram Equivalents Prescribed. AB - BACKGROUND: Opioid-prescribing patterns have been implicated as a contributing factor to the opioid epidemic, yet few evidence-based guidelines exist to assist health-care providers in assessing and possibly modifying their prescribing practices. METHODS: Five orthopaedic hand surgeons at a level-I trauma center developed a postoperative prescribing guideline for 25 common hand and upper extremity outpatient procedures, which were delineated into 5 tiers. Postoperative opioid prescriptions in a 3-month period after implementation of the protocol were compared with those from a 3-month period before implementation of the protocol. RESULTS: There were 231 patients in the pre-implementation group and 287 patients in the post-implementation group. Each individual opioid protocol tier showed a significant decrease in the mean morphine milligram equivalents (MME) prescribed, ranging from a minimum decrease of 97.8% to a maximum decrease of 176.0%. After implementation, adherence to protocol was achieved in 55.1% of patients; the MME amounts prescribed were below protocol for 28.6% and above for 16.4%. The number of additional opioid prescriptions in the 1 month postoperative period was significantly less in the post-implementation group than in the pre-implementation group (p < 0.001). The total number of pills prescribed was reduced by a theoretical equivalent of over three thousand 5-mg oxycodone pills for the 287 patients in the 3-month period. CONCLUSIONS: By utilizing a simple consensus protocol, we have demonstrated success diminishing the number of opioids prescribed without leading to an increase in the number of secondary prescriptions written by our providers. These findings are encouraging and suggest that fewer opioids were left in the possession of patients, leaving fewer pills vulnerable to misuse, abuse, and diversion.

PMID- 30278004 TI - Self-Reported Postoperative Opioid-Prescribing Practices Following Commonly Performed Orthopaedic Hand and Wrist Surgical Procedures: A Nationwide Survey Comparing Attending Surgeons and Trainees. AB - BACKGROUND: Although orthopaedic surgeons have been shown to prescribe excessive amounts of opioid analgesics postoperatively, the degree in which surgical trainees contribute to this trend is unknown. The purpose of this study was to compare self-reported opioid-prescribing behavior, factors influencing this behavior, and perceptions of patient opioid utilization and disposal between hand surgeons and trainees. METHODS: Attending hand surgeons and trainees in hand, orthopaedic, and plastic surgery programs were invited to participate in a web based survey including demographic characteristics; self-reported prescribing behavior specific to 4 procedures: open carpal tunnel release, trigger finger release, thumb carpometacarpal arthroplasty, and distal radial fracture open reduction and internal fixation; and perceptions and influencing factors. Analgesic medications were converted to morphine milligram equivalents and were compared across groups of interest using independent t tests or analysis of variance for each procedure. RESULTS: A total of 1,300 respondents (266 attending surgeons, 98 fellows, 708 orthopaedic residents, and 228 plastic surgery residents) were included. Surgeons reported prescribing fewer total morphine milligram equivalents compared with residents for all 4 procedures. Personal experience was the most influential factor for prescribing behavior by surgeons and fellows. Although residents reported that attending surgeon preference was their greatest influence, most reported no direct opioid-related communication with attending surgeons. CONCLUSIONS: Residents self-report prescribing significantly higher morphine milligram equivalents for postoperative analgesia following commonly performed hand and wrist surgical procedures than attending surgeons. Poor communication between residents and attending surgeons may contribute to this finding. Residents may benefit from education on opioid prescription, and training programs should encourage direct communication between trainees and attending surgeons.

AB - INTRODUCTION: Risk factors for stiffness after arthroscopic rotator cuff repair (RCR) have been limited to studies with small patient numbers. The objective is to determine patient-related risk factors for stiffness after RCR. METHODS: The PearlDiver database was queried from 2007 to 2015 for patients undergoing isolated arthroscopic RCR. A multivariate binomial logistic regression analysis assessed for risk factors requiring a postoperative manipulation under anesthesia (MUA) or lysis of adhesions (LOA) within 9 months after RCR. RESULTS: Two hundred thirty-two of 19,229 patients (1.2%) underwent a LOA and/or MUA within 9 months after arthroscopic RCR. Significant risk factors identified were age less than 50 years (odds ratio [OR], 1.9; P < 0.0001), female gender (OR, 2.0; P < 0.0001), diabetes mellitus (DM) type I (OR, 2.7; P < 0.0001), hypothyroidism (OR, 1.3; P = 0.020), and systemic lupus erythematosus (OR, 2.1; P = 0.004). However, tobacco use was associated with a 0.5 risk of developing stiffness (P < 0.0001). DISCUSSION: Systemic lupus erythematosus, hypothyroidism, and DMI (but not DMII) in addition to young age and female gender were risk factors for LOA/MUA after arthroscopic RCR. PMID- 30278009 TI - Glenohumeral Dislocation Arthropathy: Etiology, Diagnosis, and Management. AB - Dislocation arthropathy describes the development of progressive degenerative changes of the glenohumeral joint in the setting of instability. Although the specific etiology remains unclear, the trauma of a single dislocation, repetitive injury associated with recurrent dislocations, changes in shoulder biomechanics, and complications associated with instability surgery have all been implicated in its development. Pain and restricted range of motion are the most common patient complaints. Conservative management, consisting of pain control, activity modification, and physical therapy, is the first-line treatment after the development of arthropathy. If conservative management fails, multiple surgical options exist. Arthroscopic debridement can be attempted in young, active patients and in those patients with mild-to-moderate arthropathy. Open subscapularis lengthening and capsular release can be done in patients with prior instability repairs that are overly tight. In young patients with minimal bone loss and glenoid wear, surface replacement arthroplasty and hemiarthroplasty are surgical options. In older patients with moderate-to-severe arthropathy, total shoulder or reverse shoulder arthroplasty is the preferred treatment option. Further study is needed to better predict which patients will develop dislocation arthropathy and will thus benefit from early surgical intervention. PMID- 30278010 TI - Diagnosing Sacroiliac Joint Pain. AB - The sacroiliac joint (SIJ) is a diarthrodial joint that has been implicated as a pain generator in approximately 10% to 25% of patients with mechanical low back or leg symptoms. Unique anatomic and physiologic characteristics of SIJ make it susceptible to mechanical stress and also create challenges in the diagnosis of SIJ pain. A variety of inciting causes for SIJ pain may exist, ranging from repetitive low-impact activities such as jogging to increased stress after multilevel spine fusion surgery to high-energy trauma such as in motor vehicle accidents. Similarly, wide variability exists in the clinical presentation of SIJ pain from localized pain or tenderness around the SIJ to radiating pain into the groin or even the entire lower extremity. No pathognomonic clinical history, physical examination finding, or imaging study exists that aids clinicians in making a reliable diagnosis. However, imaging combined with clinical provocative tests might help to identify patients for further investigation. Although provocative physical examination tests have not received reliable consensus, if three or more provocative tests are positive, pursuing a diagnostic SIJ injection is considered reasonable. Notable pain relief with intra-articular anesthetic injection under radiographic guidance has been shown to provide reliable evidence in the diagnosis of SIJ pain. PMID- 30278011 TI - The In Vitro Effects of Bupivacaine on Cartilage-forming Tumor Cells. AB - INTRODUCTION: Bupivacaine is a commonly used local anesthetic that has been shown to be cytotoxic to articular chondrocytes and various tumor cells. This study evaluates the in vitro effects of bupivacaine on cartilaginous tumor cells. METHODS: Multiple different cartilaginous tumors were evaluated, including enchondromas, chondroblastomas, a low-grade chondrosarcoma, which were harvested from patients during tumor resection, and a grade-II chondrosarcoma SW1535 (ATCC HTB-94). The tumor cells were treated with 0.25% and 0.5% bupivacaine at various times points, and the result was compared with that of untreated tumor cells. Tumor cell viability and apoptosis were evaluated by MTT (3-(4,5-dimethylthiazol 2-yl)-2,5-diphenyl tetrazolium bromide) assay and flow cytometry. RESULTS: The tumors were analyzed in groups according to their pathologic diagnosis. Increasing periods of exposure to bupivacaine decreased the cell viability in all tumor samples. The cytotoxicity of 0.5% bupivacaine was significantly greater than that of 0.25% bupivacaine in all tumor cells tested. DISCUSSION: At clinically relevant concentrations, in vitro exposure to bupivacaine caused a decrease in cellular viability and an increase in the induction of apoptosis in a dose- and time-dependent manner in each of the tumor cells evaluated in this study. PMID- 30278012 TI - Management of Isolated Lateral Malleolus Fractures. AB - Isolated lateral malleolus fractures represent one of the most common injuries encountered by orthopaedic surgeons. Nevertheless, appropriate diagnosis and management of these injuries are not clearly understood. Ankle stability is maintained by ligamentous and bony anatomy. The deep deltoid ligament is considered the primary stabilizer of the ankle. In the setting of an isolated lateral malleolus fracture, identifying injury to this ligament and associated ankle instability influences management. The most effective methods for assessing tibiotalar instability include stress and weight-bearing radiographs. Clinical examination findings are important but less reliable. Advanced imaging may not be accurate for guiding management. If the ankle is stable, nonsurgical management produces excellent outcomes. In the case that clinical/radiographic findings are indicative of ankle instability, surgical fixation options include lateral or posterolateral plating or intramedullary fixation. Locking plates and small or minifragment fixation are important adjuncts for the surgeon to consider based on individual patient needs. PMID- 30278013 TI - Latissimus Dorsi Tendon Rupture. AB - Isolated injury to the latissimus dorsi is rare. Partial tendon tears may be successfully treated nonsurgically. Complete tendon ruptures require surgical repair. Tendon repair can be approached either through an anterior deltopectoral incision with a secondary small posterior axillary incision or through a long posterior axillary incision. Suture anchors can be used to repair the latissimus dorsi to the humeral attachment. Although the literature is limited to single patient case series, most patients have returned to full athletic activity after surgical repair. PMID- 30278014 TI - Revisiting the Gender Gap in Orthopaedic Surgery: Investigating the Relationship Between Orthopaedic Surgery Female Faculty and Female Residency Applicants. AB - INTRODUCTION: Although women now constitute approximately half of all graduating medical students, orthopaedic surgery continues to lag behind in its ability to recruit female applicants. One hypothesis for this discrepancy is the lack of female faculty mentors at academic institutions. The three objectives of this study were the following: (1) to quantify the proportion of female orthopaedic surgery residency applicants, (2) to quantify the proportion of female orthopaedic surgery faculty, and (3) to investigate the relationship between female orthopaedic surgery faculty at an academic institution and the corresponding number of female orthopaedic surgery residency applicants. METHODS: Data from the Association of American Medical Colleges from 2005 to 2014 were used to calculate the number of medical school graduates, the number of orthopaedic surgery residency applicants, and the number of orthopaedic full-time faculty in the United States. Institutions were excluded if they had incomplete data. A Spearman rank correlation was used to assess for a correlation between the 9-year total number of female orthopaedic surgery applicants and the average number of female orthopaedic surgery faculty members. RESULTS: A total of 101 U.S. medical schools were included in the final analysis. During the period examined, women accounted for 48.7% of medical school graduates, 14.9% of orthopaedic surgery applicants, and 13.2% of full-time orthopaedic surgery faculty. The percentage of female residency applicants increased from 13.91% in 2005 to 2006 to 16.02% in 2013 to 2014 while the percentage of female faculty increased from 12.26% in 2005 to 2006 to 15.79% in 2013 to 2014. No correlation was found between the average number of female orthopaedic surgery faculty at an institution and the total number of female orthopaedic surgery applicants from that institution during the study period examined (Rho, 0.0176; P = 0.5957). CONCLUSIONS: The data presented in this study failed to demonstrate a relationship between the number of female faculty and the number of women who apply into orthopaedic surgery, which highlights the complex nature of this issue. More research is needed to examine factors influencing the recruitment of female medical students. PMID- 30278015 TI - Cost Comparison of Femoral Distraction Osteogenesis With External Lengthening Over a Nail Versus Internal Magnetic Lengthening Nail. AB - INTRODUCTION: Femoral lengthening is performed by distraction osteogenesis via lengthening over a nail (LON) or by using a magnetic lengthening nail (MLN). MLN avoids the complications of external fixation while providing accurate and easily controlled lengthening. However, the increased cost of implants has led many to question whether MLN is cost-effective compared with LON. METHODS: A retrospective review was performed comparing consecutive femoral lengthenings using either LON (n = 19) or MLN (n = 39). The number of surgical procedures, time to union, and amount of lengthening were compared. Cost analysis was performed using both hospital and surgeon payments. Costs were adjusted for inflation using the Consumer Price Index. RESULTS: No difference was observed in the length of femoral distraction. Patients treated with MLN underwent fewer surgeries (3.1 versus 2.1; P < 0.001) and had a shorter time to union (136.7 versus 100.2 days; P = 0.001). Total costs were similar ($50,255 versus $44,449; P = 0.482), although surgeon fees were lower for MLN ($4,324 versus $2,769; P < 0.001). DISCUSSION: Although implants are more expensive for MLN than LON, this appears to be offset by fewer procedures. Overall, the two procedures had similar total costs, but MLN was associated with a decreased number of procedures and shorter time to union. LEVEL OF EVIDENCE: III. PMID- 30278016 TI - Clinical Practice Guidelines in Action: Differences in Femoral Neck Fracture Management by Trauma and Arthroplasty Training. AB - INTRODUCTION: The purpose of this study was to survey trauma and arthroplasty surgeons to investigate associations between subspecialty training and management of geriatric femoral neck fractures and to compare treatments with the American Academy of Orthopaedic Surgeons clinical practice guidelines. METHODS: Five hundred fifty-six surgeons completed the online survey consisting of two sections: (1) surgeon demographics and (2) two geriatric hip fracture cases with questions regarding treatment decisions. RESULTS: In both clinical scenarios, arthroplasty surgeons were more likely than trauma surgeons to recommend total hip arthroplasty (THA) (case 1: 96% versus 84%; case 2: 29% versus 10%; P <= 0.02) and spinal anesthesia (case 1: 70% versus 40%; case 2: 62% versus 38%; P < 0.01). Surgeons who have made changes based on clinical practice guidelines (n = 96; 21% of surveyed) cited more use of THA (n = 56; 58% of respondents) and cemented stems (n = 28; 29% of respondents). CONCLUSION: Arthroplasty surgeons are more likely to recommend THA over hemiarthroplasty and have a higher expectation for spinal anesthesia for the management of geriatric femoral neck fractures. PMID- 30278017 TI - Electrical Injuries of the Hand and Upper Extremity. AB - High-voltage electrical injuries are relatively rare injuries that pose unique challenges to the treating physician, yet the initial management follows well established life-saving, trauma- and burn-related principles. The upper extremities are involved in most electrical injuries because they are typically the contact points to the voltage source. The amount of current that passes through a specific tissue is inversely proportional to the tissue's intrinsic resistance with electricity predominantly affecting the skeletal muscle secondary to its large volume in the upper extremity. Therefore, cutaneous burns often underestimate the true extent of the injury because most current is through the deep tissues. Emergent surgical exploration is reserved for patients with compartment syndrome; otherwise, initial debridement can be delayed for 24 to 48 hours to allow tissue demarcation. Early rehabilitation, wound coverage, and delayed deformity reconstruction are important concepts in treating electrical injuries. PMID- 30278018 TI - Label-free Identification of Antibody-mediated Rejection in Cardiac Allograft Biopsies Using Infrared Spectroscopic Imaging. AB - BACKGROUND: Antibody-mediated rejection (AMR) in cardiac allograft recipients remains less well-understood than acute cellular rejection, is associated with worse outcomes, and portends a greater risk of developing chronic allograft vasculopathy. Diffuse immunohistochemical (IHC) C4d staining of capillary endothelia in formalin-fixed, paraffin-embedded (FFPE) right ventricular (RV) endomyocardial biopsies is diagnostic of immunopathologic AMR but serves more as a late-stage marker. Infrared (IR) spectroscopy may be a useful tool in earlier detection of rejection. We performed mid-IR spectroscopy to identify a unique biochemical signature for AMR. METHODS: A total of 30 posttransplant FFPE RV tissue biopsies (14 positive for C4d and 16 negative for C4d) and 14 native heart biopsies were sectioned for IR analysis. IR images of entire sections were acquired and regions of interest (ROI) from cardiomyocytes were identified. Extracted spectra were averaged across many pixels within each ROI. Principal component analysis coupled with linear discriminant analysis (PCA-LDA) and predictive classifiers were applied to the data. RESULTS: Comparison of averaged mid-IR spectra revealed unique features among C4d-positive, C4d-negative, and native heart biopsies. PCA-LDA and classification models demonstrated that spectral features from the mid-IR fingerprint region of these 3 groups permitted accurate automated classification into each group. CONCLUSIONS: In cardiac allograft biopsies with immunopathologic AMR, IR spectroscopy reveals a biochemical signature unique to AMR compared to that of nonrejecting cardiac allografts and native hearts. Future study will focus on the predictive capabilities of this IR signature. PMID- 30278019 TI - An Update on the Management of Adult Traumatic Nerve Injuries-Replacing Old Paradigms: A Review. AB - Acute nerve injuries are routinely encountered in multisystem trauma patients. Advances in surgical treatment of nerve injuries now mean that good outcomes can be achieved. Despite this, old mantras associated with management of nerve injuries, including "wait a year to see if recovery occurs" and "there's nothing we can do", persist. Practicing by these mantras places these patients at a disadvantage.Changes begin to occur in the nerve, neuromuscular junction, and muscle from the moment a nerve injury occurs. These changes can become irreversible approximately 18-24 months following denervation. Thus, it is a race to reestablish a functional nerve-muscle connection prior to these irreversible changes. Good outcomes rely on appropriate acute management and avoiding delays in care. Primary nerve surgery options include direct primary repair, nerve graft repair, and nerve transfer. Acute management of nerve injuries proceeds according to the rule of 3s and requires early cooperation between trauma surgeons who recognize the nerve injury and consultant nerve surgeons.Care of patients with acute, traumatic nerve injuries should not be delayed. Awareness of current management paradigms among trauma surgeons will help facilitate optimal upfront management. With the ever-expanding surgical options for management of these injuries and the associated improvement of outcomes, early multidisciplinary approaches to these injuries has never been more important. Old mantras must be replaced with new paradigms in order to continue to see improvements in outcomes for these patients. The importance of this review is to raise awareness among trauma surgeons of new paradigms for management of traumatic nerve injuries. PMID- 30278020 TI - Does the incidence of thoracic aortic injury warrant the routine use of chest computed tomography in children? AB - BACKGROUND: Thoracic aortic injury is a potentially life-threatening injury associated with rapid deceleration mechanisms. Diagnosis is made by chest computed tomography (CT), which is associated with a risk of radiation-induced malignancy. We sought to determine the incidence of aortic injuries in the pediatric population to weigh against the risk of CT imaging. METHODS: The Pediatric Health Information Systems (PHIS) was queried for children <=18 years with discharge diagnosis code of thoracic aortic injury (901.0) between December 2004 and 2014. Data abstracted included patient age, gender, diagnosis and procedure codes, and discharge disposition, where available. We also queried for imaging codes to determine what type of chest imaging the child received. RESULTS: Between December 2004 and 2014, 311,850 children were admitted to PHIS hospitals with traumatic injury. Of these patients, 46 (0.015%) were coded with a thoracic aortic injury and an accompanying E-code. Twenty-seven patients (58.7%) were male and the median age was 13 years. The most common mechanism of injury was motor vehicle collision (63%, n=29). Eighteen hospitals (41.9%) had no patients with a thoracic aortic injury in the 10-year period. In children with a thoracic aortic injury the mortality rate was 11% (n=5) and 22 (47.8%) underwent a chest CT during their hospitalization. Forty percent (124,909) of all trauma patients underwent chest CT, with a positive rate for aortic injury of 1.8/10,000. The reported estimated cancer risk from a chest CT scan is 25/10,000 for girls and 7.5/10, 000 in boys, greater than the positive CT rate. 3 CONCLUSION: Thoracic aortic injuries are rare in children in the United States. The risk of cancer associated with screening chest CT is greater than the likelihood of identifying an aortic injury. Therefore, screening chest CT scans are unwarranted in injured children.

AB - BACKGROUND: Following the Hartford Consensus meetings, the Stop the Bleed Campaign was created to reduce the prevalence of death from exsanguination in the case of traumatic hemorrhage. The campaign revolves around providing hemorrhage control training to members of the public and increasing public access to hemorrhage control equipment. To our knowledge, no medical school has established a self-sustaining Stop the Bleed program to train their students and faculty as well as made hemorrhage control equipment available for use in an emergency. METHODS: Bleeding Control classes were offered at the Frank H. Netter MD School of Medicine beginning in January 2018. A proposal was made to the medical school's Council on Curriculum Oversight in May 2018 to incorporate the training as part of the required curriculum for first-year students. A second proposal was made to Quinnipiac University's Emergency Management Team in June 2018 to purchase hemorrhage control equipment. RESULTS: Twelve bleeding control courses were held between January and August 2018. Two hundred and ten medical students, 19 faculty members, and 36 public safety officers completed initial training. Thirty-four medical students, two faculty members, and two public safety officers became certified instructors. Training was incorporated into the first-year curriculum to be taught by certified second-year students under the direction of the school's Department of Surgery. The school purchased approved training equipment. A student-coordinator position was created in the Surgery Interest Group. Hemorrhage control equipment was purchased for each public safety officer, patrol vehicles, and for the Central Dispatch headquarters. Public-access equipment has been purchased for each Automated External Defibrillator cabinet at the medical school. CONCLUSIONS: The School of Medicine community has been empowered with the ability to save lives. Students and faculty have been trained in life-saving skills, a self-sustaining training process has been created, and equipment has been purchased for hemorrhage control efforts.

AB - : One of the key elements of remote damage control resuscitation (RDCR) is a hemostatic resuscitation strategy to prevent the triad of coagulopathy, acidosis and hypothermia. Transfusion of whole blood has been an effective solution for both military and civilian patients, and appears to be superior to individual component therapy. At first, whole blood seems to be the ideal solution for RDCR, but it has some clinical and logistic drawbacks that may limit its use in the prehospital, battlefield, austere, and remote settings, or during multiple casualty or massive transfusion scenarios. The ideal resuscitation product for RDCR after traumatic hemorrhagic shock would be light-weight, long lasting, easily stored in large quantities, free from refrigeration, carry no risk of blood-borne infection or ABO-incompatibility, and carry out the same physiological functions as blood. Lyophilized plasma appears to fulfil many of these criteria, and is in current clinical use. There have been promising preclinical investigations of haemoglobin-based oxygen carriers (HBOC) and lyophilized platelet preparations, and one HBOC is in clinical use. It seems feasible that in the near future there may be a total blood substitution strategy for RDCR that is priority based, aimed at repaying the oxygen debt, restoration of the endothelium, and mitigation of coagulopathy and inflammatory dysregulation.

AB - Using Chlamydia trachomatis anorectal specimens routinely tested for LGV (2008 2011) and samples of archived specimens tested for LGV (2012-2015), we observed increased LGV positivity among men-who-have-sex-with-men attending NYC Sexual Health Clinics. Using clinical data, we determined predictors of anorectal LGV that may guide clinical management. PMID- 30278026 TI - Associations Between Cannabis Use, Sexual Behavior, and STIs/HIV in a Cohort of Young Men Who Have Sex with Men. AB - BACKGROUND: Among men who have sex with men (MSM) the relationship between sexually transmitted infections (STIs) and cannabis use is not well established. We assessed cannabis use, sexual behavior, and STIs including HIV in a diverse cohort of young MSM. METHODS: In Los Angeles the mSTUDY cohort conducted visits every 6 months with 512 MSM between 2014 and 2017 collecting demographics, sexual behaviors, and reports of frequency of substance use. Each visit conducted testing for gonorrhea, chlamydia and syphilis via blood, urine, and pharyngeal and rectal swabs by PCR, HIV was assessed using rapid tests for HIV negatives and viral load for HIV positives. We analyzed the relationship between cannabis use, sexual behaviors and STIs/HIV across 1,535 visits. RESULTS: Significantly fewer participants tested positive for STIs at visits when reporting the previous 6 months use of only cannabis (11.7%) compared to no drugs (16.3%) or other drugs (20.0%), (p=0.01). Fewer MSM reporting only cannabis use than no or other drug use had been incarcerated, had incarcerated partners, experienced interpersonal violence, and were HIV positive. In multivariable analyses visits with positive STIs were associated with other drug use (adjusted odds ratio (AOR) 1.69, 95% CI (1.03-2.78)) but not use of cannabis only or no drug use after controlling for age, HIV status, new sex partners, and number of sex partners. CONCLUSIONS: When MSM reported using cannabis exclusively fewer STIs were detected and lower risk sexual engagements reported than when MSM reported no drug or other drug use.

AB - BACKGROUND: This study aimed to increase understanding of the clustering of sexual behaviors in an urban sample of emerging adults, and the individual and neighborhood factors associated with sexual behavior patterns in order to provide insight into reducing the disproportionate burden of poor sexual outcomes among urban African Americans. METHODS: We draw on two cohorts of urban, predominantly African American youth first assessed at age 6 and follow-up to emerging adulthood (mean age 20, n=1,618). Latent class analyses by gender identified co occurrence of sexual behavior. RESULTS: We found three classes for both males and females: high-risk (13% of males, 15% of females), low-risk (54% of males, 56% of females) and no-risk (33% of males, 29% of females). Membership in the high-risk class was associated with school dropout, a substance use disorder diagnosis, having a criminal arrest, pregnancy, and STDs for both males and females. High risk females also had higher rates of depression. Low-risk males and females also had elevated risk of pregnancy and parenthood. Neighborhood factors distinguished the high- and no-risk classes for males and females, including the neighborhood environment scale, which assessed poverty, safety, drug activity, and crime/violence in the neighborhood. Neighborhood religiosity was inversely associated with membership in the high-risk class compared to the no-risk class for females only. Neighborhood racism distinguished those in the high-risk class compared to the no-risk class for males. CONCLUSION: Future work should take into account the clustering of sexual risk behaviors. Specific neighborhood factors could be addressed to reduce sexual health disparities.

PMID- 30278030 TI - Chlamydia, Gonorrhea, and HIV Infection among Transgender Women and Transgender Men Attending Clinics That Provide STD Services in Six US Cities: Results from the STD Surveillance Network. AB - BACKGROUND: Transgender women and transgender men are disproportionately affected by HIV infection and may be vulnerable to other STDs, but the lack of surveillance data inclusive of gender identity hinders prevention and intervention strategies. METHODS: We analyzed data from 506 transgender women (1,045 total visits) and 120 transgender men (209 total visits) who attended 26 publicly funded clinics that provide STD services in six US cities during a 3.5 year observation period. We used clinical and laboratory data to examine the proportion of transgender women and transgender men who tested positive for urogenital and extragenital chlamydial or gonococcal infections and who self reported or tested positive for HIV infection during the observation period. RESULTS: Of the transgender women tested, 13.1% tested positive for chlamydia and 12.6% tested positive for gonorrhea at one or more anatomic sites, and 14.2% were HIV-infected. Of transgender men tested, 7.7% and 10.5% tested positive for chlamydia and gonorrhea at one or more anatomic sites, and 8.3% were HIV infected., Most transgender women (86.0% and 80.9%, respectively) and more than a quarter of transgender men (28.6% and 28.6%, respectively) with an extragenital chlamydial or gonococcal infection had a negative urogenital test at the same visit. CONCLUSIONS: Publicly funded clinics providing STD services are likely an important source of STD care for transgender persons. More data are needed to understand the most effective screening approaches for urogenital, rectal, and pharyngeal CT and GC infections in transgender populations.

AB - BACKGROUND We evaluated the nephroprotective effect of diosmetin in streptozotocin (STZ)-induced diabetic nephropathy (DN) mice. MATERIAL AND METHODS Diabetes was induced by injecting STZ (50 mg/kg) i.p. for 5 days. Biochemical parameters, such as fasting blood glucose, creatinine, BUN in the serum, and albumin in the urine, were determined in STZ-induced DN mice after the 8th week of STZ administration. The level of inflammatory mediators in the serum and oxidative stress parameters in the tissue homogenate was estimated in STZ-induced DN mice. Expressions of Akt, NF-kappaB, and iNOS in the tissue homogenate were assessed by Western blot analysis. RESULTS Our data reveal that treatment with diosmetin significantly reduces the fasting blood glucose (FBG), serum creatinine, and blood urea nitrogen (BUN) in the serum and albumin in urine compared to the negative control group. Treatment with diosmetin attenuated the altered level of oxidative stress parameters and inflammatory cytokines in the STZ-induced DN mice. Expression of Akt and nuclear factor kappa-light-chain enhancer of activated B cells (NF-kappaB) was significantly reduced and inducible nitric oxide synthase (iNOS) was enhanced in the tissue homogenate of diosmetin treated mice compared to the negative control group. Data from immunohistochemical analysis suggest that the expressions of NF-kappaB was significantly reduced in tissues of the diosmetin-treated group compared to the negative control group. CONCLUSIONS Our study shows that diosmetin protects against renal injury in STZ-induced diabetic nephropathy mice by modulating the Akt/NF-kappaB/iNOS signaling pathway. PMID- 30278037 TI - Is adaptive therapy natural? AB - Research suggests that progression-free survival can be prolonged by integrating evolutionary principles into clinical cancer treatment protocols. The goal is to prevent or slow the proliferation of resistant malignant cell populations. The logic behind this therapy relies on ecological and evolutionary processes. These same processes would be available to natural selection in decreasing the probability of an organism's death due to cancer. We propose that organisms' anticancer adaptions include not only ones for preventing cancer but also ones for directing and retarding the evolution of life-threatening cancer cells. We term this last strategy natural adaptive therapy (NAT). The body's NAT might include a lower than otherwise possible immune response. A restrained immune response might forego maximum short-term kill rates. Restraint would forestall immune-resistant cancer cells and produce long-term durable control of the cancer population. Here, we define, develop, and explore the possibility of NAT. The discovery of NAT mechanisms could identify new strategies in tumor prevention and treatments. Furthermore, we discuss the potential risks of immunotherapies that force the immune system to ramp up the short-term kill rates of malignant cancer cells in a manner that undermines the body's NAT and accelerates the evolution of immune resistance. PMID- 30278038 TI - Cryptochrome: The magnetosensor with a sinister side? AB - Over the last three decades, evidence has emerged that low-intensity magnetic fields can influence biological systems. It is now well established that migratory birds have the capacity to detect the Earth's magnetic field; it has been reported that power lines are associated with childhood leukemia and that pulsed magnetic fields increase the production of reactive oxidative species (ROS) in cellular systems. Justifiably, studies in this field have been viewed with skepticism, as the underlying molecular mechanisms are unknown. In the accompanying paper, Sherrard and colleagues report that low-flux pulsed electromagnetic fields (PEMFs) result in aversive behavior in Drosophila larvae and ROS production in cell culture. They further report that these responses require the presence of cryptochrome, a putative magnetoreceptor. If correct, it is conceivable that carcinogenesis associated with power lines, PEMF-induced ROS generation, and animal magnetoreception share a common mechanistic basis.

PMID- 30278039 TI - Familiarity modulates social approach toward stressed conspecifics in female rats. AB - Familiarity between conspecifics may influence how social affective cues shape social behaviors. In a social affective preference test, experimental rats, when given the choice to explore an unfamiliar stressed or a naive adult, will avoid interaction with a stressed conspecific. To determine if familiarity would influence social interactions with stressed conspecifics, male and female test rats underwent 2 social affective preference tests in isosexual triads where an experimental rat was presented with a naive and a stressed target conspecific who were either familiar (cagemate) or unfamiliar. Male and female experimental rats avoided stressed unfamiliar conspecifics. However, experimental female rats demonstrated a preference to interact with their stressed, familiar cagemates. Male and female rats exhibited more self-grooming and immobility behavior in the presence of stressed conspecifics, which may indicate emotion contagion. These findings suggest a sex-specific role of familiarity in social approach and avoidance, and warrant further mechanistic exploration. PMID- 30278041 TI - A nested compartmental model to assess the efficacy of paratuberculosis control measures on U.S. dairy farms. AB - Paratuberculosis, also known as Johne's disease (JD), is a chronic contagious disease, caused by Mycobacterium avium subsp. paratuberculosis (MAP). The disease is incurable, fatal and causes economic losses estimated to exceed 200 million dollars to the U.S. dairy industry annually. Several preventive and control measures have been recommended; however, only a few of these measures have been validated empirically. Using a nested compartmental (NC) modeling approach, the main objective of this research was to identify the best combination of control and preventive measures that minimizes the prevalence and incidence of JD and the risk of MAP occurrence in a dairy herd. The NC model employs both MAP transmission estimates and data on pen movement of cattle on a dairy to quantify the effectiveness of control and preventive measures. To obtain reasonable ranges of parameter values for between-pen movements, the NC model was fitted to the movement data of four typical California dairy farms. Using the estimated ranges of the movement parameters and those of JD from previous research, the basic reproduction number was calculated to measure the risk of MAP occurrence in each pen environment as well as the entire dairy. Although the interventions evaluated by the NC model were shown to reduce the infection, no single measure alone was capable of eradicating the infection. The numerical simulations suggest that a combination of test and cull with more frequent manure removal is the most effective method in reducing incidence, prevalence and the risk of MAP occurrence. Other control measures such as limiting calf-adult cow contacts, raising calves in a disease-free herd or colostrum management were less effective. PMID- 30278043 TI - Feeding ecology of fishes associated with artificial reefs in the northwest Gulf of Mexico. AB - The feeding ecology of two reef fishes associated with artificial reefs in the northwest Gulf of Mexico (GoM) was examined using gut contents and natural stable isotopes. Reefs were divided into three regions (east, central, west) across an east to west gradient of increasing reef complexity and salinity. Gray triggerfish (Balistes capriscus) primarily consumed reef-associated prey (xanthid crabs, bivalves, barnacles) and pelagic gastropods, while red snapper (Lutjanus campechanus) diets were mainly comprised of non-reef prey (stomatopods, fishes, portunid crabs). Natural stable isotopes of carbon (delta13C), nitrogen (delta15N), and sulfur (delta34S) were measured in consumer muscle tissue as well as potential primary producers. Gray triggerfish occupied a lower trophic position than red snapper, with lower delta13C and delta15N values across all size classes and regions, and generally higher delta34S values. Red snapper had a smaller range of stable isotope values and corrected standard ellipse areas across all size classes and regions, indicating a smaller isotopic niche. Contribution estimates of particulate organic matter (26 to 54%) and benthic microalgae (BMA, 47 to 74%) for both species were similar, with BMA contributions greater across all three size classes (juveniles, sub-adults, adults) of red snapper and all but the juvenile size class for gray triggerfish. Species gut contents and stable isotopes differed by region, with fishes consuming more crabs in the east region and more gastropods in the central and west regions. delta13C and delta15N values generally decreased from east to west, while delta34S increased across this gradient. Results highlight species-specific feeding differences associated with artificial reefs, where gray triggerfish may be more dependent on the reef structure for foraging opportunities. In addition, results offer further information on the integral role of BMA in primary production at nearshore artificial reefs. PMID- 30278042 TI - Properties of viable lyopreserved amnion are equivalent to viable cryopreserved amnion with the convenience of ambient storage. AB - Human amniotic membrane (AM) has a long history of clinical use for wound treatment. AM serves as a wound protective barrier maintaining proper moisture. AM is anti-inflammatory, anti-microbial and antifibrotic, and supports angiogenesis, granulation tissue formation and wound re-epithelialization. These properties of AM are attributed to its native extracellular matrix, growth factors, and endogenous cells including mesenchymal stem cells. Advances in tissue preservation have helped to overcome the short shelf life of fresh AM and led to the development of AM products for clinical use. Viable cryopreserved amnion (VCAM), which retains all native components of fresh AM, has shown positive outcomes in clinical trials for wound management. However, cryopreservation requires ultra-low temperature storage and shipment that limits widespread use of VCAM. We have developed a lyopreservation technique to allow for ambient storage of living tissues. Here, we compared the structural, molecular, and functional properties of a viable lyopreserved human amniotic membrane (VLAM) with properties of VCAM using in vitro and in vivo wound models. We found that the structure, growth factors, and cell viability of VLAM is similar to that of VCAM and fresh AM. Both, VCAM and VLAM inhibited TNF-alpha secretion and upregulated VEGF expression in vitro under conditions designed to mimic inflammation and hypoxia in a wound microenvironment, and resulted in wound closure in a diabetic mouse chronic wound model. Taken together, these data demonstrate that VLAM structural and functional properties are equivalent to VCAM but without the constraints of ultra-low temperature storage. PMID- 30278044 TI - Beating the odds: Sustained Chagas disease vector control in remote indigenous communities of the Argentine Chaco over a seven-year period. AB - BACKGROUND: Rapid reinfestation of insecticide-treated dwellings hamper the sustained elimination of Triatoma infestans, the main vector of Chagas disease in the Gran Chaco region. We conducted a seven-year longitudinal study including community-wide spraying with pyrethroid insecticides combined with periodic vector surveillance to investigate the house reinfestation process in connection with baseline pyrethroid resistance, housing quality and household mobility in a rural section of Pampa del Indio mainly inhabited by deprived indigenous people (Qom). METHODOLOGY/PRINCIPAL FINDINGS: Despite evidence of moderate pyrethroid resistance in local T. infestans populations, house infestation dropped from 31.9% at baseline to 0.7% at 10 months post-spraying (MPS), with no triatomine found at 59 and 78 MPS. Household-based surveillance corroborated the rare occurrence of T. infestans and the house invasion of other four triatomine species. The annual rates of loss of initially occupied houses and of household mobility were high (4.6-8.0%). Housing improvements did not translate into a significant reduction of mud-walled houses and refuges for triatomines because most households kept the former dwelling or built new ones with mud walls. CONCLUSIONS/SIGNIFICANCE: Our results refute the assumption that vector control actions performed in marginalized communities of the Gran Chaco are doomed to fail. The larger-than-expected impacts of the intervention program were likely associated with the combined effects of high-coverage, professional insecticide spraying followed by systematic vector surveillance-and-response, broad geographic coverage creating a buffer zone, frequent housing replacement and residential mobility. The dynamical interactions among housing quality, mobility and insecticide-based control largely affect the chances of vector elimination. PMID- 30278045 TI - Low-intensity electromagnetic fields induce human cryptochrome to modulate intracellular reactive oxygen species. AB - Exposure to man-made electromagnetic fields (EMFs), which increasingly pollute our environment, have consequences for human health about which there is continuing ignorance and debate. Whereas there is considerable ongoing concern about their harmful effects, magnetic fields are at the same time being applied as therapeutic tools in regenerative medicine, oncology, orthopedics, and neurology. This paradox cannot be resolved until the cellular mechanisms underlying such effects are identified. Here, we show by biochemical and imaging experiments that exposure of mammalian cells to weak pulsed electromagnetic fields (PEMFs) stimulates rapid accumulation of reactive oxygen species (ROS), a potentially toxic metabolite with multiple roles in stress response and cellular ageing. Following exposure to PEMF, cell growth is slowed, and ROS-responsive genes are induced. These effects require the presence of cryptochrome, a putative magnetosensor that synthesizes ROS. We conclude that modulation of intracellular ROS via cryptochromes represents a general response to weak EMFs, which can account for either therapeutic or pathological effects depending on exposure. Clinically, our findings provide a rationale to optimize low field magnetic stimulation for novel therapeutic applications while warning against the possibility of harmful synergistic effects with environmental agents that further increase intracellular ROS. PMID- 30278047 TI - Should police have access to genetic genealogy databases? Capturing the Golden State Killer and other criminals using a controversial new forensic technique. AB - On April 24, 2018, a suspect in California's notorious Golden State Killer cases was arrested after decades of eluding the police. Using a novel forensic approach, investigators identified the suspect by first identifying his relatives using a free, online genetic database populated by individuals researching their family trees. In the wake of the case, media outlets reported privacy concerns with police access to personal genetic data generated by or shared with genealogy services. Recent data from 1,587 survey respondents, however, provide preliminary reason to question whether such concerns have been overstated. Still, limitations on police access to genetic genealogy databases in particular may be desirable for reasons other than current public demand for them. PMID- 30278046 TI - Multimodal MRI suggests that male homosexuality may be linked to cerebral midline structures. AB - The neurobiology of sexual preference is often discussed in terms of cerebral sex dimorphism. Yet, our knowledge about possible cerebral differences between homosexual men (HoM), heterosexual men (HeM) and heterosexual women (HeW) are extremely limited. In the present MRI study, we addressed this issue investigating measures of cerebral anatomy and function, which were previously reported to show sex difference. Specifically, we asked whether there were any signs of sex atypical cerebral dimorphism among HoM, if these were widely distributed (providing substrate for more general 'female' behavioral characteristics among HoM), or restricted to networks involved in self referential sexual arousal. Cortical thickness (Cth), surface area (SA), subcortical structural volumes, and resting state functional connectivity were compared between 30 (HoM), 35 (HeM) and 38 (HeW). HoM displayed a significantly thicker anterior cingulate cortex (ACC), precuneus, and the left occipito temporal cortex compared to both control groups. These differences seemed coordinated, since HoM also displayed stronger cortico-cortical covariations between these regions. Furthermore, functional connections within the default mode network, which mediates self- referential processing, and includes the ACC and precuneus were significantly weaker in HoM than HeM and HeW, whereas their functional connectivity between the thalamus and hypothalamus (important nodes for sexual behavior) was stronger. In addition to these singular features, HoM displayed 'female' characteristics, with a similar Cth in the left superior parietal and cuneus cortices as HeW, but different from HeM. These data suggest both singular and sex atypical features and motivate further investigations of cerebral midline structures in relation to male homosexuality. PMID- 30278049 TI - Elimination testing with adapted scoring reduces guessing and anxiety in multiple choice assessments, but does not increase grade average in comparison with negative marking. AB - BACKGROUND AND HYPOTHESES: This study is the first to offer an in-depth comparison of elimination testing with the scoring rule of Arnold & Arnold (hereafter referred to as elimination testing with adapted scoring) and negative marking. As such, this study is motivated by the search for an alternative for negative marking that still discourages guessing, but is less disadvantageous for non-relevant student characteristics such a risk-aversion and does not result in grade inflation. The comparison is structured around seven hypotheses: in comparison with negative marking, elimination testing with adapted scoring leads to (1) a similar average score (no grade inflation); (2) students expressing their partial knowledge; (3) a decrease in the number of blank answers; (4) no gender bias in the number of blank answers; (5) a reduction in guessing; (6) a decrease in self-reported test anxiety; and finally (7) students preferring elimination testing with adapted scoring over negative marking. METHODOLOGY: To investigate the above hypotheses, this study implemented elimination testing with adapted scoring and negative marking in real exam settings in two courses in a Faculty of Medicine at a large university. Due to changes in the master of medicine the same two courses were taught to both students of the 1st and 2nd master in the same semester. Given that both student groups could take the same exam with different test instructions and scoring methods, a unique opportunity occurred in which elimination testing with adapted scoring and negative marking could be compared in a high-stakes testing situation. After receiving the grades on the exams, students received a questionnaire to assess their experiences. FINDINGS: The statistical analysis taking into account student ability and gender showed that elimination testing with adapted scoring is a valuable alternative for negative marking when looking for a scoring method that discourages guessing. In contrast to traditional scoring of elimination testing, elimination testing with adapted scoring does not result in grade inflation in comparison with negative marking. This study showed that elimination testing with adapted scoring reduces blank answers and finds strong indications for the reduction of guessing in comparison with negative marking. Finally, students preferred elimination testing with adapted scoring over negative marking and reported lower stress levels in elimination testing with adapted scoring in comparison with negative marking. PMID- 30278048 TI - Bioinformatic characterisation of the effector repertoire of the strawberry pathogen Phytophthora cactorum. AB - The oomycete pathogen Phytophthora cactorum causes crown rot, a major disease of cultivated strawberry. We report the draft genome of P. cactorum isolate 10300, isolated from symptomatic Fragaria x ananassa tissue. Our analysis revealed that there are a large number of genes encoding putative secreted effectors in the genome, including nearly 200 RxLR domain containing effectors, 77 Crinklers (CRN) grouped into 38 families, and numerous apoplastic effectors, such as phytotoxins (PcF proteins) and necrosis inducing proteins. As in other Phytophthora species, the genomic environment of many RxLR and CRN genes differed from core eukaryotic genes, a hallmark of the two-speed genome. We found genes homologous to known Phytophthora infestans avirulence genes including Avr1, Avr3b, Avr4, Avrblb1 and AvrSmira2 indicating effector sequence conservation between Phytophthora species of clade 1a and clade 1c. The reported P. cactorum genome sequence and associated annotations represent a comprehensive resource for avirulence gene discovery in other Phytophthora species from clade 1 and, will facilitate effector informed breeding strategies in other crops. PMID- 30278050 TI - Prediction of prkC-mediated protein serine/threonine phosphorylation sites for bacteria. AB - As an abundant post-translational modification, reversible phosphorylation is critical for the dynamic regulation of various biological processes. prkC, a critical serine/threonine-protein kinase in bacteria, plays important roles in regulation of signaling transduction. Identification of prkC-specific phosphorylation sites is fundamental for understanding the molecular mechanism of phosphorylation-mediated signaling. However, experimental identification of substrates for prkC is time-consuming and labor-intensive, and computational methods for kinase-specific phosphorylation prediction in bacteria have yet to be developed. In this study, we manually curated the experimentally identified substrates and phosphorylation sites of prkC from the published literature. The analyses of the sequence preferences showed that the substrate recognition pattern for prkC might be miscellaneous, and a complex strategy should be employed to predict potential prkC-specific phosphorylation sites. To develop the predictor, the amino acid location feature extraction method and the support vector machine algorithm were employed, and the methods achieved promising performance. Through 10-fold cross validation, the predictor reached a sensitivity of 91.67% at the specificity of 95.12%. Then, we developed freely accessible software, which is provided at http://free.cancerbio.info/prkc/. Based on the predictor, hundreds of potential prkC-specific phosphorylation sites were annotated based on the known bacterial phosphorylation sites. prkC-PSP was the first predictor for prkC-specific phosphorylation sites, and its prediction performance was promising. We anticipated that these analyses and the predictor could be helpful for further studies of prkC-mediated phosphorylation. PMID- 30278051 TI - Enhanced neutralizing antibody response induced by inactivated enterovirus 71 in cynomolgus monkeys. AB - Enterovirus 71 (EV71) is a major etiological agent of various public health issues, particularly in the Asia-Pacific region. EV71 causes hand-foot-and-mouth disease (HFMD) and is associated with serious neurological disorders in young children. A formalin-inactivated EV71 candidate vaccine (KCDC-HFMDV1-EV71) based on the C4 subgenotype was previously developed and confirmed to be a potential candidate vaccine for prevention of EV71 infection in mice. In this study, an inactivated EV71 vaccine was used for analysis of long-term immunogenicity and efficacy in cynomolgus monkeys, a common nonhuman primate model. The vaccine was immunized three times at 0, 4, and 8 weeks with either 20-MUg doses of EV71 candidate vaccine formulated with aluminum hydroxide gel adjuvant or phosphate buffered saline as a control. The group immunized with the inactivated EV71 showed significantly increased EV71-specific antibody and serum neutralizing antibody titers at 3 weeks after vaccination and maintained these elevated titers until the end of the experiment (54 weeks after vaccination). The sera from vaccinated cynomolgus monkeys showed a crossreactive neutralizing antibody response to the heterologous subtype of EV71 (B1-4, C1, and C2). These findings suggest that the inactivated EV71 candidate vaccine may be a potential vaccine candidate and valuable tool for the control of HFMD. PMID- 30278052 TI - A Holocene landscape dynamic multiproxy reconstruction: How do interactions between fire and insect outbreaks shape an ecosystem over long time scales? AB - At a multi-millennial scale, various disturbances shape boreal forest stand mosaics and the distribution of species. Despite the importance of such disturbances, there is a lack of studies focused on the long-term dynamics of spruce budworm (Choristoneura fumiferana (Clem.)) (SBW) outbreaks and the interaction of insect outbreaks and fire. Here, we combine macrocharcoal and plant macrofossils with a new proxy-lepidopteran scales-to describe the Holocene ecology around a boreal lake. Lepidopteran scales turned out to be a more robust proxy of insect outbreaks than the traditional proxies such as cephalic head capsules and feces. We identified 87 significant peaks in scale abundance over the last 10 000 years. These results indicate that SBW outbreaks were more frequent over the Holocene than suggested by previous studies. Charcoal accumulation rates match the established fire history in eastern Canada: a more fire-prone early and late Holocene and reduced fire frequency during the mid Holocene. Although on occasion, both fire and insect outbreaks were coeval, our results show a generally inverse relationship between fire frequency and insect outbreaks over the Holocene. PMID- 30278053 TI - Cost-effectiveness of financial incentives and disincentives for improving food purchases and health through the US Supplemental Nutrition Assistance Program (SNAP): A microsimulation study. AB - BACKGROUND: The Supplemental Nutrition Assistance Program (SNAP) provides approximately US$70 billion annually to support food purchases by low-income households, supporting approximately 1 in 7 Americans. In the 2018 Farm Bill, potential SNAP revisions to improve diets and health could include financial incentives, disincentives, or restrictions for certain foods. However, the overall and comparative impacts on health outcomes and costs are not established. We aimed to estimate the health impact, program and healthcare costs, and cost effectiveness of food incentives, disincentives, or restrictions in SNAP. METHODS AND FINDINGS: We used a validated microsimulation model (CVD-PREDICT), populated with national data on adult SNAP participants from the National Health and Nutrition Examination Survey (NHANES) 2009-2014, policy effects from SNAP pilots and food pricing meta-analyses, diet-disease effects from meta-analyses, and policy, food, and healthcare costs from published literature to estimate the overall and comparative impacts of 3 dietary policy interventions: (1) a 30% incentive for fruits and vegetables (F&V), (2) a 30% F&V incentive with a restriction of sugar-sweetened beverages (SSBs), and (3) a broader incentive/disincentive program for multiple foods that also preserves choice (SNAP-plus), combining 30% incentives for F&V, nuts, whole grains, fish, and plant-based oils and 30% disincentives for SSBs, junk food, and processed meats. Among approximately 14.5 million adults on SNAP at baseline with mean age 52 years, our simulation estimates that the F&V incentive over 5 years would prevent 38,782 cardiovascular disease (CVD) events, gain 18,928 quality-adjusted life years (QALYs), and save $1.21 billion in healthcare costs. Adding SSB restriction increased gains to 93,933 CVD events prevented, 45,864 QALYs gained, and $4.33 billion saved. For SNAP-plus, corresponding gains were 116,875 CVD events prevented, 56,056 QALYs gained, and $5.28 billion saved. Over a lifetime, the F&V incentive would prevent approximately 303,900 CVD events, gain 649,000 QALYs, and save $6.77 billion in healthcare costs. Adding SSB restriction increased gains to approximately 797,900 CVD events prevented, 2.11 million QALYs gained, and $39.16 billion in healthcare costs saved. For SNAP-plus, corresponding gains were approximately 940,000 CVD events prevented, 2.47 million QALYs gained, and $41.93 billion saved. From a societal perspective (including programmatic costs but excluding food subsidy costs as an intra-societal transfer), all 3 scenarios were cost-saving. From a government affordability perspective (i.e., incorporating food subsidy costs, including for children and young adults for whom no health gains were modeled), the F&V incentive was of low cost-effectiveness at 5 years (incremental cost-effectiveness ratio: $548,053/QALY) but achieved cost effectiveness ($66,525/QALY) over a lifetime. Adding SSB restriction, the intervention was cost-effective at 10 years ($68,857/QALY) and very cost effective at 20 years ($26,435/QALY) and over a lifetime ($5,216/QALY). The combined incentive/disincentive program produced the largest health gains and reduced both healthcare and food costs, with net cost-savings of $10.16 billion at 5 years and $63.33 billion over a lifetime. Results were consistent in probabilistic sensitivity analyses: for example, from a societal perspective, 1,000 of 1,000 iterations (100%) were cost-saving for all 3 interventions. Due to the nature of simulation studies, the findings cannot prove the health and cost impacts of national SNAP interventions. CONCLUSIONS: Leveraging healthier eating through SNAP could generate substantial health benefits and be cost-effective or cost-saving. A combined food incentive/disincentive program appears most effective and may be most attractive to policy-makers. PMID- 30278054 TI - Leprosy in children under 15 years of age in Brazil: A systematic review of the literature. AB - BACKGROUND: Leprosy is a chronic infectious disease neglected, caused by Mycobacterium leprae, considered a public health problem because may cause permanent physical disabilities and deformities, leading to severe limitations. This review presents an overview of the results of epidemiological studies on leprosy occurrence in childhood in Brazil, aiming to alert health planners and managers to the actual need to institute special control strategies. METHODOLOGY/PRINCIPAL FINDINGS: Data collection consisted of an electronic search for publications in eight databases: Literatura Latino-Americana e do Caribe em Ciencias da Saude (LILACS), Scientific Electronic Library Online (SciELO), PuBMed, Biblioteca Virtual em Saude (BVS), SciVerse Scopus (Scopus), CAPES theses database, CAPES journals database and Web of Science of papers published up to 2016. After apply selection criteria, twenty-two papers of studies conducted in four different regions of Brazil and published between 2001 and 2016 were included in the review. The leprosy detection rate ranged from 10.9 to 78.4 per 100,000 inhabitants. Despite affecting both sexes, leprosy was more common in boys and in 10-14-year-olds. Although the authors reported a high cure proportion (82-90%), between 1.7% and 5.5% of the individuals developed a disability resulting from the disease. CONCLUSIONS/SIGNIFICANCE: The findings of this review shows that leprosy situation in Brazilian children under 15 years is extremely adverse in that the leprosy detection rate remains high in the majority of studies. The proportion of cases involving disability is also high and reflects the difficulties and the poor effectiveness of actions aimed at controlling the disease. The authors suggest the development of studies in spatial clusters of leprosy, where beyond the routine actions established, are included news strategies of active search and campaigns and actions of educations inside the clusters of this disease. The new agenda needs to involve the precepts of ethical, humane and supportive care, in order to achieve a new level of leprosy control in Brazil. PMID- 30278055 TI - Duplex Proximity Sequencing (Pro-Seq): A method to improve DNA sequencing accuracy without the cost of molecular barcoding redundancy. AB - A challenge in the clinical adoption of cell-free DNA (cfDNA) liquid biopsies for cancer care is their high cost compared to potential reimbursement. The most common approach used in liquid biopsies to achieve high specificity detection of circulating tumor DNA (ctDNA) among a large background of normal cfDNA is to attach molecular barcodes to each DNA template, amplify it, and then sequence it many times to reach a low-error consensus. In applications where the highest possible specificity is required, error rate can be lowered further by independently detecting the sequences of both strands of the starting cfDNA. While effective in error reduction, the additional sequencing redundancy required by such barcoding methods can increase the cost of sequencing up to 100-fold over standard next-generation sequencing (NGS) of equivalent depth. We present a novel library construction and analysis method for NGS that achieves comparable performance to the best barcoding methods, but without the increase in sequencing and subsequent sequencing cost. Named Proximity-Sequencing (Pro-Seq), the method merges multiple copies of each template into a single sequencing read by physically linking the molecular copies so they seed a single sequencing cluster. Since multiple DNA copies of the same template are compared for consensus within the same cluster, sequencing accuracy is improved without the use of redundant reads. Additionally, it is possible to represent both senses of the starting duplex in a single cluster. The resulting workflow is simple, and can be completed by a single technician in a work day with minimal hands on time. Using both cfDNA and cell line DNA, we report the average per-mutation detection threshold and per-base analytical specificity to be 0.003% and >99.9997% respectively, demonstrating that Pro-Seq is among the highest performing liquid biopsy technologies in terms of both sensitivity and specificity, but with greatly reduced sequencing costs compared to existing methods of comparable accuracy. PMID- 30278056 TI - Tutorial for using SliceOmatic to calculate thigh area and composition from computed tomography images from older adults. AB - OBJECTIVE: Area of muscle, fat, and bone is often measured in thigh CT scans when tissue composition is a key outcome. SliceOmatic software is commonly referenced for such analysis but published methods may be insufficient for new users. Thus, a quick start guide to calculating thigh composition using SliceOmatic has been developed. METHODS: CT images of the thigh were collected from older (69 +/- 4 yrs, N = 24) adults before and after 12-weeks of resistance training. SliceOmatic was used to segment images into seven density regions encompassing fat, muscle, and bone from -190 to +2000 Hounsfield Units [HU]. The relative contributions to thigh area and the effects of tissue density overlap for skin and marrow with muscle and fat were determined. RESULTS: The largest contributors to the thigh were normal fat (-190 to -30 HU, 29.1 +/- 7.4%) and muscle (35 to 100 HU, 48.9 +/ 8.2%) while the smallest were high density (101 to 150 HU, 0.79 +/- 0.50%) and very high density muscle (151 to 200 HU, 0.07 +/- 0.02%). Training significantly (P<0.05) increased area for muscle in the very low (-29 to -1 HU, 5.5 +/- 7.9%), low (0 to 34 HU, 9.6 +/- 16.8%), normal (35 to 100 HU, 4.2 +/- 7.9%), and high (100 to 150 HU, 70.9 +/- 80.6%) density ranges for muscle. Normal fat, very high density muscle and bone did not change (P>0.05). Contributions to area were altered by ~1% or less and the results of training were not affected by accounting for skin and marrow. CONCLUSIONS: When using SliceOmatic to calculate thigh composition, accounting for skin and marrow may not be necessary. We recommend defining muscle as -29 to +200 HU but that smaller ranges (e.g. low density muscle, 0 to 34 HU) can easily be examined for relationships with the health condition and intervention of interest. TRIAL REGISTRATION: Clinicaltrials.gov NCT02261961. PMID- 30278057 TI - Cataract significantly influences quantitative measurements on swept-source optical coherence tomography angiography imaging. AB - PURPOSE: To analyze retinal blood flow before and after cataract surgery using swept-source optical coherence tomography angiography (SS-OCTA). METHODS: Prospective observational study. Consecutive patients were recruited and scanned using SS-OCTA before and after cataract surgery. Laser flare photometry were performed post-surgery. Perfusion and vessel density of superficial (SCP) and deep capillary plexuses (DCP) of the 3 * 3 mm images as well as foveal avascular zone (FAZ) measurements were assessed. Vessel continuity, vessel visibility and presence of artefacts were evaluated by two blinded graders using a predefined grading protocol. RESULTS: Thirteen eyes of 12 patients met the inclusion criteria. There was a significant increase of perfusion and vessel densities in both the SCP and the DCP after cataract surgery within the 3 * 3 mm images. Significantly better distinguishability of FAZ border was observed postoperatively in both SCP and DCP, however, FAZ area and perimeter measurements did not significantly change after cataract surgery. Mean number of motion artifacts in SCP and DCP numerically decreased by 37% (P = .089) and 42% (P = .080). CONCLUSIONS: Lens opacities have a significant influence on retinal blood flow measurements in SS-OCTA and should be considered in quantitative vessel analysis. Inflammation may also impact the assessment of density parameters. FAZ measurements seems to be the most robust parameters in terms of media opacity. PMID- 30278058 TI - A multicenter comparison of quantification methods for antisense oligonucleotide induced DMD exon 51 skipping in Duchenne muscular dystrophy cell cultures. AB - BACKGROUND: Duchenne muscular dystrophy is a lethal disease caused by lack of dystrophin. Skipping of exons adjacent to out-of-frame deletions has proven to restore dystrophin expression in Duchenne patients. Exon 51 has been the most studied target in both preclinical and clinical settings and the availability of standardized procedures to quantify exon skipping would be advantageous for the evaluation of preclinical and clinical data. OBJECTIVE: To compare methods currently used to quantify antisense oligonucleotide-induced exon 51 skipping in the DMD transcript and to provide guidance about the method to use. METHODS: Six laboratories shared blinded RNA samples from Duchenne patient-derived muscle cells treated with different amounts of exon 51 targeting antisense oligonucleotide. Exon 51 skipping levels were quantified using five different techniques: digital droplet PCR, single PCR assessed with Agilent bioanalyzer, nested PCR with agarose gel image analysis by either ImageJ or GeneTools software and quantitative real-time PCR. RESULTS: Differences in mean exon skipping levels and dispersion around the mean were observed across the different techniques. Results obtained by digital droplet PCR were reproducible and showed the smallest dispersion. Exon skipping quantification with the other methods showed overestimation of exon skipping or high data variation. CONCLUSIONS: Our results suggest that digital droplet PCR was the most precise and quantitative method. The quantification of exon 51 skipping by Agilent bioanalyzer after a single round of PCR was the second-best choice with a 2.3-fold overestimation of exon 51 skipping levels compared to digital droplet PCR. PMID- 30278059 TI - Variation sites at the HLA-G 3' untranslated region confer differential susceptibility to HIV/HPV co-infection and aneuploidy in cervical cell. AB - Post-transcriptional regulatory elements associated with transcript degradation or transcript instability have been described at the 3' untranslated region (3'UTR) of the HLA-G gene. Considering that HPV infection and aneuploidy, which causes gene instability, are associated with cervical cell malignancy, as well as the fact that HIV infection and HLA-G may modulate the immune response, the present study aimed to compare the frequencies of HLA-G 3'UTR polymorphic sites (14-base pair insertion/deletion, +3142C/G, and +3187A/G) between 226 HIV+ women co-infected (n = 82) or not with HPV (n = 144) and 138 healthy women. We also evaluated the relationship between those HLA-G 3'UTR variants and aneuploidy in cervical cells. HPV types and HLA-G polymorphisms were determined by PCR and sequencing of cervical samples DNA. Aneuploidy in cervical cell was measured by flow cytometry. The HLA-G 3'UTR 14-bp ins/del was not associated with either HIV nor HIV/HPV co-infection. The +3142G allele (p = 0.049) and +3142GG genotype (p = 0.047) were overrepresented in all HIV-infected women. On the other hand, the +3187G allele (p = 0.028) and the +3187GG genotype (p = 0.026) predominated among healthy women. The +3142G (p = 0.023) and +3187A (p = 0.003) alleles were associated with predisposition to HIV infection, irrespective of the presence or not of HIV/HPV co-infection. The diplotype formed by the combination of the +3142CX (CC or CG) and +3187AA genotype conferred the highest risk for aneuploidy in cervical cell induced by HPV. The HLA-G 3'UTR +3142 and +3187 variants conferred distinct susceptibility to HIV infection and aneuploidy. PMID- 30278060 TI - Helps from flipped classroom in learning suturing skill: The medical students' perspective. AB - BACKGROUND: Today, flipped classroom (FC) has been widely used in medical education. However, the effectiveness of FC remains controversial. The variation may cause by different subjects or different course design. Moreover, those studies did not explain how the association among different domains of learning objective was in FCs. The purpose of this study was to explore the help of learning domains from a FC of suturing skill in year-5 medical students. DESIGN: This study determined sample size according to statistical power. A minimum number of 77 participants for regression analysis are needed. Therefore, this study enrolled 78 medical students in a 2-hour suturing course, which consisted of pre-class video and in-class instruction. Both simple and mattress suturing were taught. The students received an anonymous survey with questionnaire of Help from Instruction Questionnaire for Clinical Skills (HIQ-CS) after the course. The HIQ-CS was developed by medical education team according to Bloom's taxonomy, and its reliability was favorable (Cronbach's ^l = 0.839). Factor loadings among all items in the HIQ-CS was also favorable (0.790 to 0.849). This study determined consensus of students' perspective by median (Me) and interquartile range (IQR), and tested mediation among different learning domains by regression. RESULTS: The results showed medical students agreed FC can help them in learning suturing (Me = 4, IQR = 1). The cognitive help (beta = .526, p < .001) was completely mediated by psychomotor help (beta = .399, p < .001) and affective help (beta = .413, p < .001) to overall helps in FC. The affective help (beta = .617, p < .001) was partially mediated by psychomotor help to overall helps in FC. CONCLUSIONS: FC may help students in learning suturing skill in different domains. Our model explains the cognitive help from FC provides an important foundation for the helps of other domains. Although the model should be examined by different curricula and measurements in future, the model of help from instruction in our study provided an innovated concept and framework in medical education.

PMID- 30278061 TI - The relationship between anogenital HPV types and incident HIV infection among men who have sex with men and transgender women in Lima, Peru: Findings from a prospective cohort study. AB - Although it is known that individuals living with HIV have a higher HPV prevalence, the impact of individual HPV types on HIV acquisition is less clear. In this prospective cohort study we investigated the relationship between HPV types and incident HIV infection among men who have sex with men (MSM) and transgender women (TW) in Lima, Peru. Six hundred HIV-negative Peruvian MSM and TW participated in a 2-year study with biannual visits. At baseline, participants completed a computerized, self-administered questionnaire on sexual behavior and HPV knowledge and underwent a physical exam including anogenital swabs for HPV DNA (37 genotypes via linear array testing) and HIV testing; follow-up visits included the questionnaire and HIV testing. Participant mean age was 25 years (range = 18-40), with 48.9% self-identifying as gay and 86.5% reporting having sex exclusively with men. At baseline, 530 participants had HPV DNA present (61.1% with high-risk HPV, 84.9% with low-risk HPV). Among 571 participants who returned for any study visit, 73 (12.8%) became infected with HIV during the 2 year follow-up (6% HIV incidence). Compared to those without HIV, more participants with HIV had any HPV type present (97.3% vs. 87.6%, respectively, p = .01), more than one HPV type (79.5% vs. 58.2%, p < .01), or high-risk HPV (72.6% vs. 51.4%, p < .01). Some participants lost to follow-up could have been HIV-positive, which would have affected the relationship of HPV and HIV infection. Our prospective study showed that participants with any HPV type, more than one HPV type, or high-risk HPV were more likely to test positive for HIV. Although most studies have shown HPV-HIV coinfection, our findings illustrate the strong relationship between individual HPV types and HIV infection. This further illustrates the potential utility of HPV vaccine for MSM and TW, not only for HPV prevention but also possibly for HIV prevention. PMID- 30278063 TI - Optimal clustering under uncertainty. AB - Classical clustering algorithms typically either lack an underlying probability framework to make them predictive or focus on parameter estimation rather than defining and minimizing a notion of error. Recent work addresses these issues by developing a probabilistic framework based on the theory of random labeled point processes and characterizing a Bayes clusterer that minimizes the number of misclustered points. The Bayes clusterer is analogous to the Bayes classifier. Whereas determining a Bayes classifier requires full knowledge of the feature label distribution, deriving a Bayes clusterer requires full knowledge of the point process. When uncertain of the point process, one would like to find a robust clusterer that is optimal over the uncertainty, just as one may find optimal robust classifiers with uncertain feature-label distributions. Herein, we derive an optimal robust clusterer by first finding an effective random point process that incorporates all randomness within its own probabilistic structure and from which a Bayes clusterer can be derived that provides an optimal robust clusterer relative to the uncertainty. This is analogous to the use of effective class-conditional distributions in robust classification. After evaluating the performance of robust clusterers in synthetic mixtures of Gaussians models, we apply the framework to granular imaging, where we make use of the asymptotic granulometric moment theory for granular images to relate robust clustering theory to the application. PMID- 30278064 TI - Screening tool to identify adolescents living with HIV in a community setting in Zimbabwe: A validation study. AB - INTRODUCTION: A simple cost-effective strategy to pre-screen for targeted HIV testing can have substantial benefit in high burden and resource limited settings. A 4-item (previous hospitalisation, orphanhood, poor health status, and recurring skin problems) screening tool to identify adolescents living with HIV has previously shown high sensitivity in healthcare facility settings. We validated this screening tool in a community setting, in Harare, Zimbabwe in a community-based HIV prevalence survey. METHODS: A community-based HIV prevalence survey was conducted among individuals aged 8-17 years with guardian consent and child assent and residing in 7 communities during the period February 2015 to December 2015. Participants without previously diagnosed HIV were evaluated for the probability of having HIV using the screening tool. HIV status was defined using an anonymous HIV test which was done using Oral Mucosal Transudate (OMT). A questionnaire was also administered to ascertain self-reported HIV status and screening tool items. The validity of a 4-item screening tool was tested. Sensitivity and specificity of the screening tool was assessed against the HIV status based on OMT result. RESULTS: Prevalence survey participants were 5386 children who had an HIV test result, aged 8-17 years. However, 5384, who did not report testing HIV positive and responded to all screening tool item questions were included in the validation. Their median age was 12 (IQR: 10-15) years, 2515 (46.7%) were male. HIV prevalence was 1.3% (95% CI:1.0-1.8%). The 4-item screening tool had poor accuracy with an area under the receiver operating curve of 0.65(95% CI: 0.60-0.72) at a cut-off score>=1. Its sensitivity was 56.3% (95% CI:44.0-68.1%) and specificity of 75.1% (95% CI:73.9-76.3%), PPV of 2.9% (95% CI:2.1-3.9%) and a NPV of 99.2% (95% CI:98.9-99.5%). The number needed to test to diagnose one child using the screening tool was 55% lower than universal testing for HIV. CONCLUSION: Use of the 4-item screening tool could be a strategy that can be adopted to identify children living with HIV in a community setting in resource limited settings by reducing the number needed to test compared to universal testing since it is inexpensive, easy to administer and not harmful. However, screening items adapted to a community setting need to be explored to improve the performance of the screening tool. PMID- 30278065 TI - Intragenus (Homo) variation in a chemokine receptor gene (CCR5). AB - Humans have a comparatively higher rate of more polymorphisms in regulatory regions of the primate CCR5 gene, an immune system gene with both general and specific functions. This has been interpreted as allowing flexibility and diversity of gene expression in response to varying disease loads. A broad expression repertoire is useful to humans-the only globally distributed primate due to our unique adaptive pattern that increased pathogen exposure and disease loads (e.g., sedentism, subsistence practices). The main objective of the study was to determine if the previously observed human pattern of increased variation extended to other members of our genus, Homo. The data for this study are mined from the published genomes of extinct hominins (four Neandertals and two Denisovans), an ancient human (Ust'-Ishim), and modern humans (1000 Genomes). An average of 15 polymorphisms per individual were found in human populations (with a total of 262 polymorphisms). There were 94 polymorphisms identified across extinct Homo (an average of 13 per individual) with 41 previously observed in modern humans and 53 novel polymorphisms (32 in Denisova and 21 in Neandertal). Neither the frequency nor distribution of polymorphisms across gene regions exhibit significant differences within the genus Homo. Thus, humans are not unique with regards to the increased frequency of regulatory polymorphisms and the evolution of variation patterns across CCR5 gene appears to have originated within the genus. A broader evolutionary perspective on regulatory flexibility may be that it provided an advantage during the transition to confrontational foraging (and later hunting) that altered human-environment interaction as well as during migration to Eurasia and encounters with novel pathogens. PMID- 30278066 TI - Associations between mother-preschooler attachment and maternal depression symptoms: A systematic review and meta-analysis. AB - The current study aimed to systematically review and meta-analyze concurrent and longitudinal associations between maternal depression symptoms and mother-child attachment during the preschool period (aged 2 to 7 years) as assessed using the coding systems by Cassidy and Marvin (1992) and Main and Cassidy (1988). The review was pre-registered with PROSPERO (International Prospective Register of Systematic Reviews; Registration number CRD42017073417) and was conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta Analyses) guidelines. A total of 7,969 records were screened and 18 articles were deemed as eligible for inclusion in the review. Studies were reviewed using qualitative synthesis techniques and, where appropriate, meta-analysis. Qualitative synthesis indicated that mothers of disorganized/controlling children most consistently reported the highest levels of depressive symptoms, both concurrently and longitudinally. The association between disorganized/controlling child attachment and concurrent maternal depressive symptoms was significant (n = 1,787; g = 0.27, 95% CI [0.13,0.40]), and was not moderated by sample type, child gender, or risk of bias. Findings of a relationship between child attachment insecurity and maternal depressive symptoms must be qualified due to significant within-study heterogeneity and publication bias. Results suggest that maternal depressive symptoms may confer risk for disorganized/controlling attachment during the preschool period. PMID- 30278067 TI - Is topical or intravenous tranexamic acid preferred in total hip arthroplasty? A randomized, controlled, noninferiority clinical trial. AB - PURPOSE: The present study aimed to confirm the efficacy and safety of topical and intravenous tranexamic acid (TXA) compared with that of topical placebo and to assess the noninferiority between the two application methods of TXA in patients undergoing unilateral primary total hip arthroplasty. METHODS: Our randomized controlled trial investigated 170 patients with 1:1:1 allocation to two doses of 10-mg/kg intravenous TXA, 3-g topical TXA, and topical placebo of 60 ml physiological saline groups. The primary outcome, total blood loss, was calculated with Nadler and Gross formula. The secondary outcomes included allogeneic blood transfusion requirement, drain blood loss, decreased hemoglobin level. Noninferiority would be established when the upper limit 95% CI is lower than 250 ml of the noninferiority margin for the mean difference of total blood loss between topical and intravenous TXA. Thromboembolic complication incidence was considered as a safety outcome. RESULTS: The total blood loss of patients administered intravenous (mean+/-standard deviation, 1125+/-514 ml) and topical TXA (1211+/-425 ml) was significantly reduced compared with that of those administered topical placebo (1464+/-556 ml) (p = 0.0012). Drain blood loss and hemoglobin level reduction in patients administered with TXA were also significantly lower than those in patients administered topical placebo. The mean difference of total blood loss between topical and intravenous TXA is 86 ml (95% CI, -88 to 260 ml). The complications were comparable between patients managed with TXA and patients with topical placebo. CONCLUSION: The noninferiority of topical TXA to intravenous TXA can not be concluded. Considering no significant difference was found in all efficacy outcomes between the two administration methods. Any of the two TXA administration methods can be adopted for blood loss prevention in total hip arthroplasty. PMID- 30278068 TI - Visualization of the auditory pathway in rats with 18F-FDG PET activation studies based on different auditory stimuli and reference conditions including cochlea ablation. AB - Activation studies with positron emission tomography (PET) in auditory implant users explained some of the mechanisms underlying the variability of achieved speech comprehension. Since future developments of auditory implants will include studies in rodents, we aimed to inversely translate functional PET imaging to rats. In normal hearing rats, activity in auditory and non-auditory regions was studied using 18F-fluorodeoxyglucose (18F-FDG) PET with 3 different acoustic conditions: sound attenuated laboratory background, continuous white noise and rippled noise. Additionally, bilateral cochlea ablated animals were scanned. 3D image data were transferred into a stereotaxic standard space and evaluated using volume of interest (VOI) analyses and statistical parametric mapping (SPM). In normal hearing rats alongside the auditory pathway consistent activations of the nucleus cochlearis (NC), olivary complex (OC) and inferior colliculus (IC) were seen comparing stimuli with background. In this respect, no increased activation could be detected in the auditory cortex (AC), which even showed deactivation with white noise stimulation. Nevertheless, higher activity in the AC in normal hearing rats was observed for all 3 auditory conditions against the cochlea ablated status. Vice versa, in ablated status activity in the olfactory nucleus (ON) was higher compared to all auditory conditions in normal hearing rats. Our results indicate that activations can be demonstrated in normal hearing animals based on 18F-FDG PET in nuclei along the central auditory pathway with different types of noise stimuli. However, in the AC missing activation with respect to the background advises the need for more rigorous background noise attenuation for non-invasive reference conditions. Finally, our data suggest cross-modal activation of the olfactory system following cochlea ablation-underlining, that 18F-FDG PET appears to be well suited to study plasticity in rat models for cochlear implantation. PMID- 30278069 TI - Differential sonographic features of the extensor pollicis longus tendon rupture and other finger tendons rupture in the setting of hand and wrist trauma. AB - PURPOSE: To investigate the difference between sonographic findings in extensor pollicis longus tendons rupture and other finger tendons rupture in patients sustaining hand and wrist trauma. METHODS: Twenty-four patients who presented with signs and symptoms clinically suspicious for tendon injury and surgically confirmed tendon rupture were included in this study. We analyzed 6 sonographic features: discontinuity of the tendon, pseudomass formation, decreased echogenicity of the tendon, retraction of the ruptured tendon, fluid collection within the tendon sheath, and the motion of the tendon. We compared the sonographic features of ruptured extensor pollicis longus tendons with the other ruptured finger tendons. RESULTS: Discontinuity of the tendon was the most common sonographic findings and retraction of the ruptured tendon was the second most common findings. Fourteen of 16 cases with a dynamic study on sonography showed loss of normal motion of the tendon. Pseudomass formation was the second most common feature in ruptured extensor pollicis longus tendons, in contrast to the other ruptured finger tendons (p < 0.05). CONCLUSION: Using ultrasonography, detection of discontinuity of the tendon, retraction of the ruptured tendon, and limitation of tendon motion could be very helpful for diagnosing a tendon rupture in hand and wrist trauma. Pseudomass formation could be more specific for diagnosing extensor pollicis longus tendon ruptures compared with other finger tendons.

PMID- 30278071 TI - Dietary or supplemental fermentable fiber intake reduces the presence of Clostridium XI in mouse intestinal microbiota: The importance of higher fecal bacterial load and density. AB - OBJECTIVES: Clostridium difficile infection is a public health concern. C. difficile was found in healthy human intestine as a member of Clostridium XI. Because soluble fermentable fiber ingestion affects intestinal microbiota, we used fiber-containing diets to determine the intestinal microbial condition that could reduce the presence of Clostridium XI. METHODS: Newly weaned male mice were assigned to three published diets: Control AIN-93G purified diet with only poorly fermented cellulose; Control plus 5% purified fermentable fiber inulin; Chow with wheat, soybean and corn that provide a mixture of unpurified dietary fibers. Methods were developed to quantify 24-hour fecal microbial load and microbial DNA density. The relative abundance of bacterial genera and the bacterial diversity were determined through 16S rRNA sequence-based fecal microbiota analysis. RESULTS: Mice adjusted food intake to maintain the same energy intake and body weight under these three moderate-fat (7% w:w) diets. Chow-feeding led to higher food intake but also higher 24-h fecal output. Chow-feeding and 1-8 wk ingestion of inulin-supplemented diet increased daily fecal microbial load and density along with lowering the prevalence of Clostridium XI to undetectable. Clostridium XI remained undetectable until 4 weeks after the termination of inulin supplemented diet. Fermentable fiber intake did not consistently increase probiotic genera such as Bifidobacterium or Lactobacillus. Chow feeding, but not inulin supplementation, increased the bacterial diversity. CONCLUSIONS: Increase fecal microbial load/density upon fermentable fiber ingestion is associated with a lower and eventually undetectable presence of Clostridium XI. Higher bacterial diversity or abundance of particular genera is not apparently essential. Future studies are needed to see whether this observation can be translated into the reduction of C. difficile at the species level in at-risk populations. PMID- 30278072 TI - Quantitative phosphoproteomic analysis identifies novel functional pathways of tumor suppressor DLC1 in estrogen receptor positive breast cancer. AB - Deleted in Liver Cancer-1 (DLC1), a member of the RhoGAP family of proteins, functions as a tumor suppressor in several cancers including breast cancer. However, its clinical relevance is unclear in breast cancer. In this study, expression of DLC1 was correlated with prognosis using publicly available breast cancer gene expression datasets and quantitative Reverse Transcription PCR in cohorts of Estrogen Receptor-positive (ER+) breast cancer. Low expression of DLC1 correlates with poor prognosis in patients with ER+ breast cancer with further decrease in metastatic lesions. The Cancer Genome Atlas (TCGA) data showed that down regulation of DLC1 is not due to methylation or mutations. To seek further insights in understanding the role of DLC1 in ER+ breast cancer, we stably overexpressed DLC1-full-length (DLC1-FL) in T-47D breast cancer cells; this inhibited cell colony formation significantly in vitro compared to its control counterpart. Label-free global proteomic and TiO2 phosphopeptide enrichment assays (ProteomeXchange identifier PXD008220) showed that 205 and 122 phosphopeptides were unique to DLC1-FL cells and T-47D-control cells, respectively, whereas 6,726 were quantified by phosphoproteomics analysis in both conditions. The top three significant clusters of differentially phosphopeptides identified by DAVID pathway analysis represent cell-cell adhesion, mRNA processing and splicing, and transcription regulation. Phosphoproteomics analysis documented an inverse relation between DLC1 expression and several phosphopeptides including epithelial cell transforming sequence 2 (ECT2). Decreased phosphorylation of ECT2 at the residue T359, critical for its active conformational change, was validated by western blot. In addition, the ECT2 T359 containing phosphopeptide was detected in both basal and luminal patient-derived breast cancers breast cancer phosphoproteomics data on the Clinical Proteomic Tumor Analysis Consortium (CPTAC) Assay portal. Together, for the first time, this implicates ECT2 phosphorylation in breast cancer, which has been proposed as a therapeutic target in lung cancer. In conclusion, this data suggests that low expression of DLC1 is associated with poor prognosis. Targeting ECT2 phosphopeptides could provide a promising mechanism for controlling poor prognosis seen in DLC1low ER+ breast cancer. PMID- 30278073 TI - Geographical variations and influential factors in prevalence of cardiometabolic diseases in South Korea. AB - Geographical variations and influential factors of disease prevalence are crucial information enabling optimal allocation of limited medical resources and prioritization of appropriate treatments for each regional unit. The purpose of this study was to explore the geographical variations and influential factors of cardiometabolic disease prevalence with respect to 230 administrative districts in South Korea. Global Moran's I was calculated to determine whether the standardized prevalences of cardiometabolic diseases (hypertension, stroke, and diabetes mellitus) were spatially clustered. The CART algorithm was then applied to generate decision tree models that could extract the diseases' regional influential factors from among 101 demographic, economic, and public health data variables. Finally, the accuracies of the resulting model-hypertension (67.4%), stroke (62.2%), and diabetes mellitus (56.5%)-were assessed by ten-fold cross validation. Marriage rate was the main determinant of geographic variation in hypertension and stroke prevalence, which has the possibility that married life could have positive effects in lowering disease risks. Additionally, stress related variables were extracted as factors positively associated with hypertension and stroke. In the opposite way, the wealth status of a region was found to have an influence on the prevalences of stroke and diabetes mellitus. This study suggested a framework for provision of novel insights into the regional characteristics of diseases and the corresponding influential factors. The results of the study are anticipated to provide valuable information for public health practitioners' cost-effective disease management and to facilitate primary intervention and mitigation efforts in response to regional disease outbreaks.

PMID- 30278074 TI - Does nutritional status affect Parkinson's Disease features and quality of life? AB - OBJECTIVES: The aim of this study was to determine the relationship between nutritional status and Parkinson's Disease (PD) features in association with depression, anxiety and quality of life in people with PD. MATERIALS AND METHODS: This study was conducted on 96 patients with idiopathic PD to whom the following scales were applied: Unified Parkinson's Disease Rating Scale (UPDRS), 39-item PD questionnaire (PDQ-39), Hospital Anxiety and Depression Score (HADS), Mini Nutritional Assessment (MNA). The scales and measurements were applied to patients at their first assessment. Patients with malnutrition or at risk of malnutrition were assessed by the dietitian and nutrition nurse. These patients received nutritional support through personalized diet recommendations and appropriate enteral nutritional products, considering factors such as age, comorbidity, socioeconomic and cultural conditions. At the end of 6 weeks, the scales and measurements applied during the first visit were again applied to the patients. RESULTS: A significant and inverse correlation was determined between mental (Spearman r:-0.510, p<0.001), activities of daily living (Spearman r: 0.520, p<0.001), motor (Spearman r:-0.480, p<0.001), complications (Spearman r: 0.346, p<0.001) UPDRS subdivisions and total scores (Spearman r:-0.644, p<0.001) and total MNA score. A significant and inverse correlation was found between all PDQ-39 subdomains and total MNA score (p<0.05). The highest inverse correlations were found in mobility (Spearman r:-0.690, p<0.001) and stigma (Spearman r: 0.570, p<0.001). Both depression (Spearman r:-0.631, p<0.001) and anxiety (Spearman r:-0.333, p<0.001) scores were determined to be inversely correlated with total MNA score. At the 6-week control visit, significantly lower scores were found in all subdivisions and in the total UPDRS score, PDQ-39 score and in the patients' anxiety and depression scores (p<0.05). MNA scores were found to be significantly higher in the assessment performed after 6 weeks of support for patients who had abnormal nutritional status at inception (p<0.001). CONCLUSION: PD motor and nonmotor functions, disease duration and severity are related to nutritional status. Quality of life was also shown to be affected by changes in the nutritional status. These results show that nutritional status assessment should be a standard approach in the PD treatment and follow-up processes. PMID- 30278075 TI - Cynomolgus monkeys (Macaca fascicularis) experimentally and naturally infected with hepatitis E virus: The bone marrow as a possible new viral target. AB - Hepatitis E virus (HEV) transmission through infected blood and blood products has already been described. However, little is known about the bone marrow (BM) as source of HEV infection. Our study aimed to investigate the presence of HEV antigen (Ag) and histological changes in BM of cynomolgus monkeys (Macaca fascicularis) experimentally and naturally infected with HEV. Four cynomolgus monkeys with acute, and two with chronic hepatitis E ? after immunosuppressive therapy with tacrolimus ? were compared with one colony-bred animal naturally infected. Both, natural and experimental infections were characterized by anti HEV IgG seroconversion detected by ELISA, and viral RNA isolation confirmed by RT qPCR and qualitative nested RT-PCR. BM biopsies were collected from all animals, submitted to histology and indirect immunofluorescence techniques and observed, respectively, by light and confocal microscopy. The HEV Ag-fluorescent-labeled cells were detected from BM biopsies obtained from three monkeys with acute and one with chronic hepatitis E, and also from the naturally infected monkey. In the experimentally infected animals with acute hepatitis, HEV Ag detection occurred at 160 days post-infection, even after viral clearance in serum, feces, and liver. Double-stranded RNA, a replicative marker, was detected in BM cells from both acute and chronically infected animals. Major histological findings included vacuolization in mononuclear and endosteal cells, an absence of organized inflammatory infiltrates, and also some fields suggesting displasic focal BM disease. These findings support the hypothesis of BM cells as secondary target sites of HEV persistence. Further experimental studies should be carried out to confirm the assumption of HEV transmission through BM transplantation.

PMID- 30278077 TI - Exploring facilitators and barriers to medication error reporting among healthcare professionals in Qatar using the theoretical domains framework: A mixed-methods approach. AB - BACKGROUND: There is a need for theory informed interventions to optimise medication reporting. This study aimed to quantify and explain behavioural determinants relating to error reporting of healthcare professionals in Qatar as a basis of developing interventions to optimise the effectiveness and efficiency of error reporting. METHODS: A sequential explanatory mixed methods design comprising a cross-sectional survey followed by focus groups in Hamad Medical Corporation, Qatar. All doctors, nurses and pharmacists were invited to complete a questionnaire that included items of behavioural determinants derived from the Theoretical Domains Framework (TDF), an integrative framework of 33 theories of behaviour change. Principal component analysis (PCA) was used to identify components, with total component scores computed. Differences in total scores among demographic groupings were tested using Mann-Whitney U test (2 groups) or Kruskal-Wallis (>2 groups). Respondents expressing interest in focus group participation were sampled purposively, and discussions based on survey findings using the TDF to provide further insight to survey findings. Ethical approval was received from Hamad Medical Corporation, Robert Gordon University, and Qatar University. RESULTS: One thousand, six hundred and four questionnaires were received (67.9% nurses, 13.3% doctors, 12.9% pharmacists). Questionnaire items clustered into six components of: knowledge and skills related to error reporting; feedback and support; action and impact; motivation; effort; and emotions. There were statistically significant higher scores in relation to age (older more positive, p<0.001), experience as a healthcare professional (more experienced most positive apart from those with the highest level of experience, p<0.001), and profession (pharmacists most positive, p<0.05). Fifty-four healthcare professionals from different disciplines participated in the focus groups. Themes mapped to nine of fourteen TDF domains. In terms of emotions, the themes that emerged as barriers to error reporting were: fear and worry on submitting a report; that submitting was likely to lead to further investigation that could impact performance evaluation and career progression; concerns over the impact on working relationships; and the potential lack of confidentiality. CONCLUSIONS: This study has quantified and explained key facilitators and barriers of medication error reporting. Barriers appeared to be largely centred on issues relating to emotions and related beliefs of consequences. Quantitative results demonstrated that while these were issues for all healthcare professionals, those younger and less experienced were most concerned. Qualitative findings highlighted particular concerns relating to these emotional aspects. These results can be used to develop theoretically informed interventions with the aims of improving the effectiveness and efficiency of the medication reporting systems impacting patient safety. PMID- 30278079 TI - Characterization of the blastogenic response to LPS of bovine peripheral blood mononuclear cells. AB - Mitogens are diverse compounds of plant and microbial origin, widely employed to test immunocompetence in animals. The blastogenic response of bovine Peripheral Blood Mononuclear Cells (PBMC) to lypopolysaccharides (LPS) has been investigated in our laboratories for a long time. In particular, a possible correlation between blastogenic response to LPS and disease resistance of periparturient dairy cows had been observed in previous studies. Most important, low responder cows presented a higher frequency of disease cases after calving, compared with high responder animals. Owing to the above, different aspects of the blastogenic response to LPS were investigated on PBMC of healthy Friesian cows, using a 72 hour Bromodeoxyuridin (BrDU) cell proliferation assay. Stimulation with LPS induced little if any replication of bovine PBMC over 72 hours despite consistent BrDU detection in all the PBMC samples under study. Poor replication of LPS stimulated PBMC was confirmed by cell cycle and cell growth flow cytometry analyses. In particular, LPS stimulation gave rise to very low percentages of S phase cells, sometimes lower than in control, unstimulated cells, as opposed to Concanavalin A-stimulated PBMC. Magnetic separation and analysis of BrDU-treated bovine PBMC after exposure to LPS showed that both B and CD4 T cells are involved in the blastogenic response to LPS, in contrast with current data based on human and murine models. Finally, LPS caused an early, specific up-regulation of TNF alpha and TLR4 genes in bovine PBMC, and significant correlations were shown between the expression of inflammatory cytokine and Indoleamine-pyrrole 2,3 dioxygenase (IDO1) genes. On the whole, our data indicate that differences in the blastogenic response to LPS could be partly accounted for by heterogenicity of responding cells (B and T lymphocytes), which might also have an impact on induction and regulation of inflammatory responses and endotoxin tolerance.

PMID- 30278081 TI - Development of a scale to assess motivation for competitive employment among persons with severe mental illness. AB - BACKGROUND: The employment rate among people with severe mental illness has recently increased, though it is still low. The motivation to work appears to be an important role as an intermediate outcome measure in vocational rehabilitation programs. In addition, measuring the work motivation for people with severe mental illness appears to be essential to identify candidates who are likely to benefit and monitor candidates' motivation in a supported employment program. This study aimed to develop a new measure for assessing both intrinsic and extrinsic motivation to work among people with severe mental illness, as there are currently no well-established instruments of this kind. METHODS: A focus group interview and review of previous qualitative research were used to identify possible items for inclusion in the new scale. A provisional scale was constructed and further refined for content and format based on feedback from a researcher and also three peer workers with severe mental illness. The resulting provisional 38-item version of the scale was completed by 136 respondents with severe mental illness, and we performed exploratory factor analysis to identify latent constructs within the new measure. The finalized scale was analyzed for test-retest reliability, internal consistency, and convergent validity. RESULT: An exploratory factor analysis yielded a four-factor scale with 23 items. The finalized 23 items had high internal consistency (Cronbach's alpha = 0.91) and relatively high test-retest reliability (ICC = 0.83). The four subscales had fair internal consistency (Cronbach's alpha >= 0.69) and good test-retest reliability (ICC >= 0.61). Convergent validity was weakly supported by the significant positive correlations with the overall question on motivation to work (r >= 0.19, p < 0.01). Besides these correlations, only the "Pressure from others" subscale was negatively and significantly correlated with the negative symptoms evaluated using the Positive and Negative Syndrome Scale (r = -0.18, p = 0.04). CONCLUSIONS: This study used factor analysis to develop a new multidimensional scale assessing motivation for competitive employment among persons with severe mental illness. The scale showed acceptable levels of reliability and factor based and convergent validity. The new measure can be used for measuring the motivation for competitive employment among people with severe mental illness, and it would be useful to identify candidates who are likely to benefit from a certain supported employment program, and to monitor interim progress of the state of participants' motivation in a program. PMID- 30278082 TI - A low meat diet increases the risk of open-angle glaucoma in women-The results of population-based, cross-sectional study in Japan. AB - BACKGROUND: Studies identifying modifiable lifestyle risk factors related to open angle glaucoma (OAG) are limited, especially from Asian countries. This study aimed to identify lifestyle risk factors for OAG in a Japanese population. METHODS AND FINDINGS: This population-based, cross-sectional study recruited Japanese participants aged 40 years or older from January 2013 to March 2015. We took fundus photographs for OAG screening, determined lifestyle and health characteristics through a questionnaire and performed physical examinations. The participants who had suspect findings in the fundus photographs were sent for a detailed ophthalmic examination to diagnose OAG. Lifestyle and heath characteristics were statistically compared between the OAG and non-OAG participants. A total of 1583 participants were included in the study, of which 42 had OAG and 1541 did not have OAG. The number of days per week that the female participants consumed meat (mean+/-SD; OAG: 1.7+/-1.2 days, non-OAG: 2.7+/-1.5 days) was negatively associated with OAG (OR = 0.61; 95% CI: 0.43-0.88; p = 0.007). Higher intraocular pressure was positively associated with OAG in men (OR = 1.20; 95% CI: 1.05-1.38, p = 0.009). No significant difference between participants with and without OAG was observed for a range of other lifestyle factors and health criteria including self-report of diabetes, number of family living together, body mass index, blood pressure, pulse rate, coffee drinking, tea drinking, alcohol drinking, number of fruits consumed per day and days of fish consumption per week. CONCLUSIONS: A higher weekly consumption of meat appears to be negatively associated with OAG in Japanese women. Increasing the dietary intake of meat can contribute to reducing the risk of developing OAG. PMID- 30278083 TI - Virtual reality assessment of walking and non-walking space in men and women with virtual reality-based tasks. AB - Far space and near space refer to different spatial features in which we unfold our behaviour. On the one hand, classical visuospatial neuropsychological tests assess spatial abilities in the near space; on the other, far space typically involves new spatial memory tasks in which participants display their behaviour in an environment, either interacting with objects or searching for targets. The Boxes Room Task is a virtual test that assesses spatial memory in the far space. Based upon this task, a new test was developed in which participants could not move about within the context, but they could actually perceive it from a specific viewpoint. In this work, both versions of the task were compared with one another. Furthermore, they were also compared with the results of 10/36 spatial recall test, a task assessing spatial memory in the near space. Two conditions were applied in all tasks, both in stable and rotated contexts. Our study included one hundred and twenty healthy young participants who were divided into two groups. The first group performed the Walking Space Boxes Room Task. A second group performed the Non-Walking Space Boxes Room Task as well as another traditional neuropsychological test for near space assessment, the 10/36 spatial recall test. Results proved that orientation in the non-walking space was more difficult than in the walking space. Additionally, our test also showed that men outperformed women in both virtual reality-based tasks, although they did not do it in the traditional 10/36 spatial recall test. In short, this work exposes that virtual-reality technologies provide tools to assess spatial memory, being more sensitive than traditional tests in the detection of small performance changes.

AB - Bambara groundnut (Vigna subterranea (L.) Verdc.) is an indigenous legume crop, cultivated by subsistence farmers throughout sub-Saharan countries. Research findings indicate that the crop has great nutritional and agronomic potential, but it remains scientifically neglected. A baseline study was conducted in seven districts in semi-arid regions of rural Zimbabwe to gather knowledge on current production and utilization of bambara groundnut, assess its role in providing sustainable food and nutrition security for rural populations and determine priorities for follow-up research. Results revealed a variety of bambara groundnut processing techniques, which included boiling, soaking, roasting and milling across the surveyed districts. Reported constraints to processing and consumption included long cooking time, difficulties with milling and high firewood and water requirements. Fifty to eighty percent of respondents in all districts consumed bambara groundnut once or twice weekly from August to December. Preferred consumer attributes were taste, the satiating effect, nutritional benefits or a combination of these. Current, culturally acceptable processing techniques need improvement to support sustainable bambara groundnut processing while optimising nutrient bio-accessibility. Ultimately, community resilience to food and nutrition insecurity can be promoted by exchange of bambara groundnut processing knowledge amongst the production areas, involving the different stakeholders in the food supply chains. PMID- 30278088 TI - Evaluation and evolution of bank efficiency considering heterogeneity technology: An empirical study from China. AB - The performances of different types of banks may vary due to heterogeneous technology, which can be examined by metafrontier analysis. However, the metafrontier constructed in most existing literature is concave, resulting in a biased estimation of efficiency. Based on 93 Chinese commercial banks over the period of 2005-2016, we first evaluate the banking efficiency by using the proposed data envelopment analysis (DEA) model, NCMeta-US-NSBM, which simultaneously incorporates a non-concave metafrontier technique, undesirable outputs, and super efficiency into a network slacks-based measure (NSBM) model. Subsequently, the evolution of banking efficiency during the study period is investigated on the basis of the Dagum Gini index and kernel density estimation methods. The main empirical results show the following. 1) There exists significant disparity/heterogeneity in banking efficiency for overall efficiency, productivity efficiency, and profitability efficiency. 2) The results of the technology gap ratio (TGR) and the evaluation of stated-owned banks (SOB), joint stock banks (JSB), and city commercial banks (CCB) in the productivity stage are higher than those in the profitability stage, indicating that most of the banks have a large space for improvement, especially for SOB and JSB in the profitability stage. 3) The major contribution of the overall difference of banking efficiency in China is the intensity of the transvariation. 4) Although the kernel density estimations for different efficiency scores have similar distributions in corresponding years, the multilevel differentiation phenomenon of banking efficiency may appear after 2008. PMID- 30278087 TI - Body condition and adrenal glucocorticoid activity affects metabolic marker and lipid profiles in captive female elephants in Thailand. AB - Studies in western zoo elephants have found relationships between body condition and physiological function, and identified mitigating management strategies to optimize health and welfare. A similar methodological approach was used in this study, which evaluated a body condition score (BCS; 1 = thinnest, 5 = fattest) every other month and fecal glucocorticoid metabolite (FGM) concentrations twice monthly in 33 tourist camp elephants in Thailand for a 1-year period to assess seasonal variations, and determine how lipid profiles [total cholesterol (TC), low density lipoproteins (LDL), high density lipoproteins (HDL), triglycerides (TG)] and metabolic parameters [insulin, glucose, fructosamine, glucose to insulin ratio (G:I)] related to measures of body condition and adrenal function. The most prevalent BCS was 3-3.5 (60.6%), with 27.3% at BCS = 4 (overweight) and 12.1% at BCS = 4.5-5 (very overweight); no elephants had a BCS <2. BCSs were higher in rainy and winter seasons compared to summer, with FGM, TG, HDL, LDL, and insulin also higher in the rainy and/or winter seasons (p<0.05). By contrast, TC and glucose were lowest in the rainy season. FGM measures were negatively associated with two environmental factors: temperature and rainfall, but not humidity. Positive correlations were found between BCS and TC, LDL, and HDL, and between FGM and TC, HDL, glucose, and insulin (p<0.05), whereas BCS and FGM were both negatively associated with the G:I (p<0.05). However, there was no relationship between BCS and FGM among the camp elephants. Using BCS and FGM measures as outcome variables in separate regression models, this study found high BCS and elevated FGM concentrations were associated with altered lipid profiles and metabolic status in elephants. Furthermore, more work hours/day was associated with better body condition and health measures. Thus, being overweight and exposed to factors that increase adrenal activity could adversely affect health status, requiring alterations in management for some individuals, whereas exercise appears to have a protective effect.

PMID- 30278089 TI - Trace metals, organic carbon and nutrients in the Beidagang Wetland Nature Reserve, northern China. AB - This study aimed to determine sediment contamination in the Beidagang Wetland Nature Reserve to describe atmospheric deposition of trace metals. We analyzed Hg, Cd, Pb, TOC, TN, TP, delta13C, and delta15N, and studied their variations in surface sediments and in the vertical profiles of sediment cores collected from the reserve. Evaluation of environmental trace metal contamination using sediment quality guidelines and geochemical background values indicated that the risk of metal pollution in the reserve sediments was relatively low. Concentrations of Hg, Cd, and Pb in the sediments were much lower than concentrations in sediment samples from Bohai Bay and polluted rivers in Tianjin. Enrichment factors indicate that samples are moderately contaminated with Hg, Cd, and Pb; whereas the geo-accumulation index results classify the sediments as uncontaminated to moderately contaminated with Hg, Cd, and Pb. The distribution patterns of trace metal concentrations in the three core samples were uniform. delta13C and delta15N were used to track the sources of TOC and TN in sediments. Results show that TOC mainly originated from the residue and decaying matter of aquatic plants (e.g., algae, reeds, and Typha), while TN was derived from soil N and elevated atmospheric N deposition. Because domestic and industrial waste is not discharged into the Beidagang Wetland Nature Reserve, trace metals found in sediments mainly originate from atmospheric deposition. The results provide baseline data for analysis of trace metal accumulation in Beijing-Tianjin-Hebei, a region subject to atmospheric deposition in northern China.

AB - Although primary caregivers of young adult grandchildren are generally not older women, a limited number of aged grandmothers assume this critical role. It is beneficial for the public to understand the lived experiences of these caregivers. For many different reasons, older grandmother caregivers freely provide valuable, person-centered care in their homes. They respond, on an ongoing basis, to the many care needs of their young adult grandchildren. Over time, their caregiving experiences can be satisfying and challenging. Because their services are provided to their young adult grandchildren at home, the collaborative efforts of health professionals, caregivers, and care recipients are essential. Therefore, researchers and health professionals can use conceptual models that emphasize wholeness, unity, and collaborative decision making to frame their understanding of the phenomenon of older grandmother caregivers, consider the influential factors, and determine the practice implications for this population.

PMID- 30278092 TI - Molecular dynamics provides insight into how N251A and N251Y mutations in the active site of Bacillus licheniformis RN-01 levansucrase disrupt production of long-chain levan. AB - Produced by levansucrase, levan and levan oligosaccharides (GFn) have potential applications in food and pharmaceutical industries such as prebiotics, anti-tumor and anti-inflammatory agents. Previous study reported that Bacillus licheniformis RN-01 levansucrase could produce levan oligosaccharides and long-chain levan. However, its N251A and N251Y mutants could effectively produce short-chain oligosaccharides upto GF3, but they could not produce long-chain levan. We hypothesized that these mutations probably reduced GF3 binding affinity in levansucrase active site that contains fructosyl-Asp93 intermediate and caused GF3 to be in an unfavorable orientation for transfructosylation; therefore, levansucrase could not effectively extend GF3 by one fructosyl residue to produce GF4 and subsequently long-chain levan. However, these mutations probably did not significantly reduce binding affinity or drastically change orientation of GF2; therefore, levansucrase could still extend GF2 to produce GF3. Using this hypothesis, we employed molecular dynamics to investigate effects of these mutations on GF2/GF3 binding in levansucrase active site. Our results reasonably support this hypothesis as N251A and N251Y mutations did not significantly reduce GF2 binding affinity, as calculated by MM-GBSA technique and hydrogen bond occupations, or drastically change orientation of GF2 in levansucrase active site, as measured by distance between atoms necessary for transfructosylation. However, these mutations drastically decreased GF3 binding affinity and caused GF3 to be in an unfavorable orientation for transfructosylation. Furthermore, the free energy decomposition and hydrogen bond occupation results suggest the importance of Arg255 in GF2/GF3 binding in levansucrase active site. This study provides important and novel insight into the effects of N251A and N251Y mutations on GF2/GF3 binding in levansucrase active site and how they may disrupt production of long-chain levan. This knowledge could be beneficial in designing levansucrase to efficiently produce levan oligosaccharides with desired length.

AB - A new rapid DNA solution, the RapidHIT(r) ID, can accommodate two different sample cartridges, ACE, for the analysis of a single swab and EXT, for the analysis of DNA extracts. An efficient internal validation designed for low throughput rapid DNA is described. An evaluation of the EXT sample cartridge is also described. Each cartridge generated profiles with sufficient data quality to meet CODIS eligibility in fewer than 120 min. The results exhibited 100% correlation when compared to conventional DNA typing methods. Precision, reproducibility, stochastic, mixture, and contamination experiments produced expected results. Sensitivity of the ACE sample cartridge was acceptable for buccal swab analysis. The sensitivity of the EXT sample cartridge is discussed. The ACE validation and the EXT evaluation utilized a minimalist, cost-saving, efficient design to generate a validated RapidHIT(r) ID instrument capable of producing genetic profiles from both extracted forensic DNA samples and buccal swab samples within 120 min. PMID- 30278099 TI - Apigenin as an effective anticancer natural product: Spotlight on TRAIL, WNT/beta catenin, JAK-STAT pathways, and microRNAs. AB - Wealth of information gleaned from decades of high-impact research work; scientists have disentangled the complicated web of versatile regulators that underlie cancer development and progression. Use of structural biology approaches and functional genomics have helped us to gain new insights into complex nature of cancer, and it is now clear that genetic/epigenetic mutations, overexpression of oncogenes, inactivation of tumor suppressors, loss of apoptosis, and versatility of protein binding partners have contributory roles in carcinogenesis and metastatic spread. It is becoming progressively more understandable that reprogramming of gene expression during and nontranscriptional changes during cancer development and progression are initiated and controlled by deregulated signal transduction cascades, all of which collectively create an incalculable complexity. Data obtained through preclinical and clinical trials revealed that alterations in the targeted oncogenes and other downstream, and parallel pathways played a central role in the development of resistance against different therapeutics. Phytochemicals have regained limelight, and different natural products are currently being tested for efficacy in preclinical studies. Apigenin, a plant-derived flavonoid has considerable pharmacological value and is reportedly involved in the regulation of different signaling cascades. In this review, we have attempted to summarize rapidly evolving understanding of molecular biologists and pharmacologists about the potential of apigenin in the regulation of deregulated signaling pathways in different cancers. We have emphasized on the regulation of WNT/beta-catenin and janus kinase/signal transducers and activators of transcription (JAK-STAT) pathways. We also comprehensively discuss how apigenin restored apoptosis in tumor necrosis factor related apoptosis-inducing ligand (TRAIL)-resistant cancers. The review also gives a snapshot of microRNAs (miRNAs) that regulate wide-ranging biological processes, and it is now clear that each miRNA can control hundreds of gene targets. Apigenin was noted to upregulate miR-520b and miR-101 in different cancers to inhibit tumor growth. Moreover, apigenin-induced apoptotic rate was significantly higher when used in combination with miR-423-5p inhibitors or miR 138 mimics. Better comprehension of linear and integrated signaling pathways will be helpful in effective therapeutic targeting of deregulated signaling pathways to inhibit/prevent cancer.

AB - Hand preference may be crucial in the forensic domain, notably in cases where the assailant is known to be left-handed and the defendant claims to be right-handed (or vice versa). In such cases, forensic psychologists or physicians may be asked to test the hand preference of the defendant. However, hand preference may be faked. The case described here illustrates this problem and addresses potential solutions. We also present preliminary data showing that a standard instrument for measuring handedness is sensitive to feigning. We conclude that when hand preference is determined, multiple sources of information should be assessed in order to identify possible feigning. PMID- 30278101 TI - Methanol Detected in a Subdural Hematoma as an Embalming Artifact. AB - Analysis of subdural hematomata has been used to suggest antemortem drug concentrations, with the assumption that materials within the hematoma are less subject to metabolism or degradation during any survival period and postmortem interval. We report the case of an 87-year-old woman whose death had not been reported to the coroner's office until postembalming. Autopsy revealed a traumatic brain injury with subdural hematoma causing a mass effect. Testing of the clot indicated a methanol concentration of 51.8 mg%. No additional analyses were detected. These findings suggest that methanol can be present in a postmortem hematoma sample, yet not represent a poisoning. Our findings also suggest that while the interior of hematomata do not necessarily represent completely "protected space" from postmortem diffusion of some blood constituents, such diffusion is not facile, and analysis may still provide useful indications of antemortem drugs present, if not actual concentrations. PMID- 30278102 TI - Haemolysin Sph2 of Leptospira interrogans induces cell apoptosis via intracellular reactive oxygen species elevation and mitochondrial membrane injury. AB - Leptospira interrogans causes widespread leptospirosis in humans and animals, with major symptoms of jaundice and haemorrhage. Sph2, a member of the sphingomyelinase haemolysins, is an important virulence factor for leptospire. In this study, the function and mechanism of Sph2 in the pathogenesis of leptospirosis were investigated to further understand the pathogenesis of leptospire. Real-time PCR analysis of expression levels during cell invasion showed that sph2 gene expression was transiently induced in human umbilical vein endothelial cells (HUVECs), human embryo liver cells (L02), and human epithelial lung cells (L132), with expression levels reaching a peak after 45 min of infection. Further functional analysis of recombinant Sph2 (rSph2) by LDH assays and confocal microscopy showed that rSph2 can be internalised by cells both by causing cell membrane damage and by a damage-independent clathrin-mediated endocytosis pathway. Subsequently, rSph2 is able to translocate to mitochondria, which led to an increase in the levels of reactive oxygen species (ROS) and a decrease of the mitochondrial membrane potential (DeltaPsim ). Further flowcytometry analyses after rSph2 exposure showed that 28.7%, 31%, and 27.3% of the HUVEC, L02, and L132 cells, respectively, became apoptotic. Because apoptosis could be decreased with the ROS inhibitor N-acetyl cysteine, these experiments suggested that rSph2 triggers apoptosis through mitochondrial membrane damage and ROS elevation. The ability of leptospiral haemolysin rSph2 to cause apoptosis likely contributes to the pathogenesis of leptospirosis. PMID- 30278103 TI - miR-345-5p regulates proliferation, cell cycle, and apoptosis of acute myeloid leukemia cells by targeting AKT2. AB - Acute myeloid leukemia (AML) is a malignant clonal hematopoietic disease, which is caused by hematopoietic stem cell abnormalities. Epigenetic regulation, especially of microRNAs (miRNAs), mostly results from external or environmental effects and is critical to AML. In this study, for the first time, we report that decreased expression of miR-345-5p facilitates the proliferation of leukemia cells in AML. Further study demonstrated that AKT1/2 was the target of miR-345-5p and was responsible for the dysregulation of leukemia cell proliferation and apoptosis. Inhibition of AKT1/2 ameliorated this malignant effect, which provides new insight into AML diagnosis, treatment, prognosis, and next-step translational investigations. PMID- 30278104 TI - PIP2 Phospholipid-Induced Aggregation of Tau Filaments Probed by Tip-Enhanced Raman Spectroscopy. AB - The morphology and secondary structure of peptide fibers formed by aggregation of tubulin-associated unit (Tau) fragments (K18), in the presence of the inner cytoplasmic membrane phosphatidylinositol component (PIP2 ) or heparin sodium (HS) as cofactors, are determined with nanoscale (<10 nm) spatial resolution. By means of tip-enhanced Raman spectroscopy (TERS), the inclusion of PIP2 lipids in fibers is determined based on the observation of specific C=O ester vibration modes. Moreover, analysis of amide I and amide III bands suggests that the parallel beta-sheet secondary structure content is lower and the random coil content is higher for fibers grown from the PIP2 cofactor instead of HS. These observations highlight the occurrence of some local structural differences between these fibers. This study constitutes the first nanoscale structural characterization of Tau/phospholipid aggregates, which are implicated in deleterious mechanisms on neural membranes in Alzheimer's disease. PMID- 30278105 TI - Acupuncture as a multifunctional neuroprotective therapy ameliorates cognitive impairment in a rat model of vascular dementia: A quantitative iTRAQ proteomics study. AB - AIMS: Acupuncture has been reported to affect vascular dementia through a variety of molecular mechanisms. An isobaric tag for relative and absolute quantification (iTRAQ) with high-resolution liquid chromatography-tandem mass spectrometry (LC MS/MS) analyses makes it possible to attain a global profile of proteins. Hence, we used an iTRAQ-LC-MS/MS strategy to unravel the underlying mechanism of acupuncture. METHODS: Wistar rats were subjected to vascular dementia with bilateral common carotid occlusion. Acupuncture was intervened for 2 weeks at 3 days after surgery. The Morris water maze was used to assess the cognitive function. Proteins were screened by quantitative proteomics and analyzed by bioinformatic analysis. Four differentially expressed proteins (DEPs) were validated by western blot. The reactive oxygen species (ROS) production, neuron cell loss, and long-term potentiation (LTP) were determined after western blot. RESULTS: Acupuncture at proper acupoints significantly improved cognitive function. A total of 31 proteins were considered DEPs. Gene ontology (GO) analysis showed that most of the DEPs were related to oxidative stress, apoptosis, and synaptic function, which were regarded as the major cellular processes related to acupuncture effect. Western blot results confirm the credibility of iTRAQ results. Acupuncture could decrease ROS production, increase neural cell survival, and improve LTP, which verified the three major cellular processes. CONCLUSION: Acupuncture may serve as a promising clinical candidate for the treatment of vascular dementia via regulating oxidative stress, apoptosis, or synaptic functions. PMID- 30278107 TI - Searching for Kin Amidst Tragedy-Disaster Victim Identification Operations for US Bangla Flight 211. AB - The nature of air disasters includes factors that exacerbate challenges in the identification process. Of the 49 deceased in the US Bangla air crash in Kathmandu, Nepal, four were intact, 11 presented with burn injuries, another 11 presented with partial charring, and 23 were completely charred. Personal belongings were useful in the identification phases for all types of victims. Fingerprints were obtainable and useful in intact victims and victims with less severe burn injuries; medical and surgical information was useful in bodies with burn injuries; finally, dental findings were useful in cases of extensive charring. Other useful methods in the process included marks of identification, physical features, and exclusion. In certain resource-limited settings, especially in closed population disasters, where scientific identification (DNA, dental records, etc.) is not currently available, personal belongings, clothing, and physical findings analyzed by an identification team using a structured organization may be cautiously used as the primary means of identification. PMID- 30278106 TI - Magnetic compression anastomosis for biliojejunostomy and pancreaticojejunostomy in Whipple's procedure: An initial clinical study. AB - BACKGROUND AND AIM: Magnetic anastomosis has been attempted in biliary and intestinal reconstruction. The objective of the current study was to introduce an initial clinical use of magnetic compression anastomosis for pancreaticojejunostomy and biliojejunostomy in Whipple's procedure. METHODS: Patients with peri-ampullary carcinoma and dilated bile and pancreatic ducts were prospectively enrolled from 2016 to 2017. After pancreaticoduodenectomy, an appropriate mother magnet and drainage tube was placed in the proximal bile duct and pancreatic duct. The daughter magnets were introduced to mate with the mother magnets at the anastomotic sites. A close postoperative surveillance and routine cholangiopancreaticography via the drainage tube were performed. RESULTS: One female and three male patients with a median age of 69 years (range, 57-77) were included. The diameter of the common bile ducts and pancreatic ducts ranged from 8 to 15 mm, and 7 to 10 mm, respectively. The median time duration for biliojejunostomy and pancreaticojejunostomy was 7 (range, 5-8 min) min and 9 (range, 8-10 min) min, respectively. The median time of biliojejunostomy and pancreaticojejunostomy formation was 17 (range, 15-21 days) days and 11 (range, 10-18 days), respectively. With a median follow up of 313 days, one patient developed biliary anastomotic stricture at 11 months after surgery, and underwent stent placement via percutaneous transhepatic drainage sinus, and recovered well. CONCLUSIONS: Magnetic anastomosis is safe, effective, and simple for both biliojejunostomy and pancreaticojejunostomy in Whipple's procedure. PMID- 30278108 TI - The phenomenon of lipid metabolism "cut" mutants. AB - Every cell cycle iteration culminates with the resolution of a mitotic nucleus into a pair of daughter nuclei, which are distributed between the two daughter cells. In the fission yeast Schizosaccharomyces pombe, the faithful division of a mitotic nucleus depends on unperturbed lipogenesis. Upon genetically or chemically induced perturbation of lipid anabolism, S. pombe cells fail to separate the two daughter nuclei and subsequently initiate lethal cytokinesis resulting in the so-called "cut" terminal phenotype. Evidence supporting a critical role of lipid biogenesis in successful mitosis in S. pombe has been accumulating for almost two decades, but the exact mechanism explaining the reported observations had been elusive. Recently, several studies established a functional link between biosynthesis of structural phospholipids, nuclear membrane growth, and the fidelity of "closed" mitosis in S. pombe. These novel insights suggest a mechanistic explanation for the mitotic defects characteristic for some S. pombe mutants deficient in lipid anabolism and extend our knowledge of metabolic modulation within the context of the cell cycle. In this review, we cover the essential role of lipogenesis in "closed" mitosis, focusing mainly on S. pombe as a model system. PMID- 30278109 TI - Insulin increases cholesterol uptake, lipid droplet content, and apolipoprotein B secretion in CaCo-2 cells by upregulating SR-BI via a PI3K, AKT, and mTOR dependent pathway. AB - : The actions of insulin on intestinal cholesterol absorption and lipoprotein secretion are not well understood. Herein, we determined the effects of insulin on the levels of cholesterol transporter scavenger receptor, class B, type I (SR BI), cellular cholesterol uptake, intracellular lipid accumulation, and lipoprotein secretion in a cellular model of human intestinal epithelium. METHODS: CaCo-2 cells were cultured to postconfluency in Transwell filters and stimulated with glucose (25 mM) in the presence or absence of insulin (100 nM) at their basolateral surface. SR-BI mRNA and protein levels were quantified by quantitative reverse transcription-PCR and immunoblot, respectively. Polarized localization of SR-BI was determined by cell surface proteins biotinylation and streptavidin precipitation. Activities of PI3K, AKT, mTOR, and SR-BI were pharmacologically antagonized. Cholesterol uptake was assessed by NBD-cholesterol incorporation. Apolipoprotein (apo) B concentration was quantified by ELISA. Subcellular localization of neutral lipids (BODIPY) and SR-BI (immunofluorescence) was determined by confocal microscopy. RESULTS: In polarized CaCo-2 cells, insulin increased SR-BI at the mRNA and protein levels. SR-BI was exclusively present at apical cell surface, as indicated by biotinylation and confocal microscopy analysis. Glucose did not modify SR-BI abundance or subcellular localization. Effects of insulin on SR-BI levels were abrogated by PI3K, AKT, or mTOR pharmacological antagonism. Cholesterol uptake, neutral lipid abundance, and apo B secretion were increased by insulin in CaCo-2 cells, and these effects were prevented by SR-BI pharmacological antagonism with block lipid transport-1. CONCLUSIONS: insulin promotes cholesterol uptake, intracellular lipid store, and apo B-containing lipoproteins secretion by SR-BI-dependent mechanisms in a model of human intestinal epithelium. PMID- 30278110 TI - Favorable outcomes of prepackaged low-residue diet on bowel preparation for colonoscopy: Endoscopist-blinded randomized controlled trial. AB - BACKGROUND AND AIM: 2 L polyethylene glycol plus an ascorbic acid (PEGA) is known to be as effective. However, 2 L polyethylene glycol-based regimens are often still difficult for patients to tolerate. Therefore, we conducted this study to evaluate the potential of 1 L PEGA with prepackaged low-residue diet (PLD) as an alternative to 2 L PEGA before colonoscopy. METHODS: The subjects were randomly assigned to either of the two groups. The 2 L PEGA group received 2 L PEGA split regimen. The 1 L PEGA with PLD group received PLD on the day preceding colonoscopy and 1 L PEGA. All endoscopic procedures were performed by one physician who did not know patients allocation. Bowel preparation status were graded using Boston Bowel Preparation Score (BBPS). A questionnaire regarding tolerability and safety was administered. This trial is registered at ClinicalTrials.gov (NCT03329339). RESULTS: A total of 173 patients completed the study (86 in the 2 L PEGA group and 87 in the 1 L PEGA with PLD group). Bowel preparation was adequate in 88.4% (76/86) of patients in the 2 L PEGA group and 93.1% of patients in the 1 L PEGA with PLD group (81/87, P = 0.28). The patients in the 1 L PEGA with PLD group had higher whole Boston Bowel Preparation Scale score (P = 0.02) and expressed more satisfaction and willingness to repeat the procedure (P < 0.01). There was no significant difference with respect to compliance or safety. CONCLUSION: 1 L PEGA with PLD showed equivalent efficacy, greater satisfaction, and more willingness to repeat compared with 2 L PEGA for bowel preparation. PMID- 30278111 TI - L-carnitine prevents ammonia-induced cytotoxicity and disturbances in intracellular amino acid levels in human astrocytes. AB - BACKGROUND AND AIM: L-carnitine (L-CA) has been used therapeutically to treat hepatic encephalopathy with hyperammonemia, but the mechanism by which L-CA contributes to ammonia detoxification in the brain is still unclear. Thus, the cytotoxicity and changes in intracellular amino acids (AAs) in astrocytes with hyperammonemia following L-CA administration were studied. METHODS: Human astrocytes were treated with ammonium chloride (NH4 Cl), L-CA or a mixture of NH4 Cl, and L-CA under defined conditions. Total intracellular reactive oxygen species and lactate dehydrogenase leakage were measured following different treatment periods. The intracellular levels of AAs in astrocytes were determined using metabolomic analysis. RESULTS: Intracellular total reactive oxygen species and lactate dehydrogenase leakage were significantly increased after treatment with NH4 Cl. In contrast, co-treatment with L-CA significantly inhibited the cytotoxic effects of NH4 Cl. The intracellular levels of almost all AAs involving glutamine and branched-chain AAs (BCAAs) were significantly increased in the NH4 Cl-treated cells compared with in the control cells; these changes in BCAA levels were reduced with L-CA co-treatment. Additionally, the level of 3-methyl-2 oxovaleric acid, which is a metabolite from isoleucine and plays a critical role in neurological damage, was significantly increased in the NH4 Cl-treated cells, but this metabolite was significantly decreased with L-CA co-treatment. CONCLUSION: L-CA protects human astrocytes from ammonia-induced acute cytotoxic effects and the increased intracellular levels of glutamine and BCAAs. PMID- 30278112 TI - Palladium-Catalyzed Enantioselective Addition of Chiral Metal Enolates to In Situ Generated ortho-Quinone Methides. AB - We describe herein a conceptually novel, cooperative Bronsted acid/base catalyzed process for the conjugate addition of cyclic beta-keto esters to ortho-quinone methides both generated in situ. Upon hemiacetalization, densely functionalized chiral chromans with two adjacent quaternary and additionally a tertiary stereogenic center were obtained with very good diastereoselectivity (up to >95:5 d.r.) and typically excellent enantioselectivity (up to >99 % ee). The striking feature and key to success is the dual catalytic activation of both nucleophile and electrophile in two separate cycles with a single chiral catalyst. PMID- 30278113 TI - Construction and comprehensive analysis of dysregulated long non-coding RNA associated competing endogenous RNA network in clear cell renal cell carcinoma. AB - OBJECTIVE: This study aimed to assess the long noncoding RNA (lncRNA)-microRNA (miRNA)-messenger RNA (mRNA) regulatory network in clear cell renal cell carcinoma (ccRCC) by gene expression analyses. MATERIALS AND METHODS: LncRNA, miRNA, and mRNA expression profiles in ccRCC were obtained from The Cancer Genome Atlas. Differentially expressed lncRNAs, mRNAs (cut-off: |log 2 [fold change, FC])| > 2.0 and adjusted P < 0.01) and miRNAs (|log 2FC| > 1.5 and adjusted P < 0.01) were unveiled using R. Cox regression analysis was performed to identify prognostic factors of ccRCC related to overall survival (OS). A protein-protein interaction (PPI) network was constructed for differentially expressed mRNAs (DEmRNAs) by Search Tool for the Retrieval of Interacting Genes (STRING). Key hub genes were screened from top 300 DEmRNAs. LncRNA-miRNA and miRNA-mRNA regulatory network were constructed and combined into the competing endogenous RNA regulatory network. Gene ontology biological terms were screened by STRING; Kyoto Encyclopedia of Genes and Genomes pathways were identified using the "clusterProfiler" package in R. RESULTS: A total of 2331, 1517, and 83 DEmRNAs, lncRNAs, and miRNAs were identified, respectively. Eleven lncRNAs (AC016773.1, HOTTIP, LINC00460, NALCN-AS1, PVT1, TRIM36-IT1, WT1-AS, COL18A1-AS1, LINC00443, LINC00472, and TCL6), three miRNAs (hsa-mir-21, hsa-mir-144, and hsa-mir-155), and three mRNAs (COL4A4, NOD2, and GOLGA8B) were associated with OS. Specifically, four lncRNAs (PVT1, LINC00472, TCL6, and WT1-AS1) and one mRNA (Collagen Type IV Alpha 4 Chain) were verified as independent prognostic factors by Gene Expression Profiling Interactive Analysis. Eleven key hub genes were obtained by PPI analysis. "Cell adhesion molecules (CAMs)," "chemical carcinogenesis," and "cytokine-cytokine receptor interaction" were significantly enriched in the network. CONCLUSION: The findings clarify the pathogenesis of ccRCC and might provide potential therapeutic targets. PMID- 30278114 TI - Terrorism Risk Assessment, Recollection Bias, and Public Support for Counterterrorism Policy and Spending. AB - Recollection bias (RB) refers to the phenomenon whereby after an adverse event people report that their risk assessment about a similar future event is presently no higher than their recollection of their pre-event risk assessment. While previous research has outlined this theoretical construct and generated important empirical findings, there were some limitations. We design and employ a new national representative survey to address these limitations in this study. We examine the existence and persistence of RB among the general public in the context of a number of domestic and international terrorist attacks. We further examine the socioeconomic and political base of RB and the influences of RB on a wide range of citizens' counterterrorism policy preferences. Our data analyses reveal strong evidence showing the occurrence of RB and its persistence across various forms of terrorism risk. With regard to the socioeconomic and political base, we find that females, older people, political conservatives, and Republicans are less likely to be subject to RB. For the effects of RB on public counterterrorism policy preferences, our analyses demonstrate that this bias significantly dampens public support for a wide range of preventive policy measures and government anti-terrorism spending. Overall, our study, based on a national representative sample and an extended survey design, provides robust evidence of RB in terrorism risk assessment, and adds further evidence to support the idea that RB is likely a generalizable phenomenon. Implications and suggestions for future research are discussed in the conclusion. PMID- 30278115 TI - Developing a Broadly Applicable Measure of Risk Perception. AB - Decades of research identify risk perception as a largely intuitive and affective construct, in contrast to the more deliberative assessments of probability and consequences that form the foundation of risk assessment. However, a review of the literature reveals that many of the risk perception measures employed in survey research with human subjects are either generic in nature, not capturing any particular affective, probabilistic, or consequential dimension of risk; or focused solely on judgments of probability. The goal of this research was to assess a multidimensional measure of risk perception across multiple hazards to identify a measure that will be broadly useful for assessing perceived risk moving forward. Our results support the idea of risk perception being multidimensional, but largely a function of individual affective reactions to the hazard. We also find that our measure of risk perception holds across multiple types of hazards, ranging from those that are behavioral in nature (e.g., health and safety behaviors), to those that are technological (e.g., pollution), or natural (e.g., extreme weather). We suggest that a general, unidimensional measure of risk may accurately capture one's perception of the severity of the consequences, and the discrete emotions that are felt in response to those potential consequences. However, such a measure is not likely to capture the perceived probability of experiencing the outcomes, nor will it be as useful at understanding one's motivation to take mitigation action. PMID- 30278116 TI - Exposure to parental and community violence and the relationship to bullying perpetration and victimization among early adolescents: A parallel process growth mixture latent transition analysis. AB - This study examined heterogeneity in parental and community violence exposure during middle school and its association with bullying perpetration and victimization in high school. Youth (N = 1,611) in four Midwestern middle schools participated. Parallel process growth mixture latent transition analysis was used to understand how trajectory profiles of middle school violence exposure was associated with high school bullying profiles. Impulsivity, depression, school belonging, and delinquency were assessed as moderators of the transition probabilities. A three class solution was found for violence exposure: decreasing parental violence/increasing community violence (n = 103; 6.4%), stable high parental violence and low community violence (n = 1,027; 63.7%), and increasing parental violence and stable high community violence (n = 481; 29.8%). Similarly, a three class solution was found for high school bullying: High Bullying Perpetration and High Victimization class (n = 259; 16%), Victimization only (n = 1145; 71%), and low all class (n = 207; 13%). The largest proportion of youth transitioning into the high bullying and high victimization class were from the decreasing parental violence/increasing community violence. Depression, impulsivity, school belonging, and delinquency all had various moderating effects on transition probabilities. Our findings make it apparent that early forms of parental and community violence are associated with aggressive behaviors and experiences with victimization during high school. Prevention and intervention efforts should target individuals who display early and chronic patterns of exposure to violence as these individuals have the greatest risk of later aggressive and victimization in high school. PMID- 30278117 TI - Exogenous attention and memory for faces following contextual behavioral immune system activation. AB - The behavioral immune system (BIS) is characterized by affective, cognitive and behavioral processes that work in an articulated manner to prevent the occurrence of infections. Attention and memory evolved to enhance the organism's chances of survival and have been proposed to play an important role in the BIS. The present study investigated the effects of attention and memory for neutral faces after a contextual activation of the BIS. Participants were primed, by the use of film clips, either with infectious disease concerns or non-infectious disease concerns. They performed an exogenous attentional task involving the discrimination of target letters, with face stimuli presented as distractors, which was then followed by a surprise recognition task for the faces. The results showed that participants in the infectious disease condition were more accurate in the attentional task than participants in the control condition. No significant difference between groups was found in the response times during the attention task nor in memory performance. Overall, these results suggest that the BIS might be associated with a hypervigilant state towards cues in general and that BIS activation through this type of priming may not be sufficient to clearly activate mnemonic mechanisms. PMID- 30278118 TI - Cost-Effective Sampling and Analysis for Mycotoxins in a Cereal Batch. AB - The presence of hazards (e.g., contaminants, pathogens) in food/feed, water, plants, or animals can lead to major economic losses related to human and animal health or the rejection of batches of food or feed. Monitoring these hazards is important but can lead to high costs. This study aimed to find the most cost effective sampling and analysis (S&A) plan in the cases of the mycotoxins deoxynivalenol (DON) in a wheat batch and aflatoxins (AFB1 ) in a maize batch. An optimization model was constructed, maximizing the number of correct decisions for accepting/rejecting a batch of cereals, with a budget as major constraint. The decision variables were the choice of the analytical method: instrumental method (e.g., liquid chromatography combined with mass-spectrometry (LC-MS/MS)), enzyme-linked-immuno-assay (ELISA), or lateral flow devices (LFD), the number of incremental samples collected from the batch, and the number of aliquots analyzed. S&A plans using ELISA showed to be slightly more cost effective than S&A plans using the other two analytical methods. However, for DON in wheat, the difference between the optimal S&A plans using the three different analytical methods was minimal. For AFB1 in maize, the cost effectiveness of the S&A plan using instrumental methods or ELISA were comparable whereas the S&A plan considering onsite detection with LFDs was least cost effective. In case of nonofficial controls, which do not have to follow official regulations for sampling and analysis, onsite detection with ELISA for both AFB1 in maize and DON in wheat, or with LFDs for DON in wheat, could provide cost-effective alternatives. PMID- 30278119 TI - [Predicting Care and Repercussions for Caregivers of Surgical Patients at Home]. AB - Objectives: To analyze the correlation between the state of health, knowledge, and social support of surgical patients' caregivers at home, with the intensity of nursing care and its consequences. Methods: A longitudinal observational study with follow-up at admission, discharge and 10 days following discharge at home, held in the surgical hospitalization unit at the Vic University Hospital, (Barcelona). A non-randomized and consecutive sample of 317 informal caregivers of surgical patients with abdominal surgery was included in the study. The characteristics of caregivers were studied using the Nursing Outcomes Classification indicators. The intensity of nursing care, consequences and impact on patient quality of life was evaluated through the validated ICUB97-R questionnaire. Results: Most of the caregivers were women, with an average age of 52,9 +/- 13,7years, with no previous experience as caregivers. The greatest intensity of care and impact was observed on caregivers who attended dependent and/or cancer diagnosed patients at home, dedicating the largest time to provide care (p < 0,005). Predictor variables for the occurrence of consequences during convalescence at home were emotional health satisfaction, routine activity disruption, fear, sleep pattern and being a dependent patient. Conclusions: Emotional health satisfaction, routine activity disruption, fear, sleep pattern and being a dependent patient before surgery are strong predictive variables for the occurrence of consequences on caregivers during convalescence at home. There is a significant negative correlation between punctuations in the ICUB97-R questionnaire and the Nursing Outcomes Classification indicators. PMID- 30278120 TI - Force Field Parametrization from the Hirshfeld Molecular Electronic Density. AB - The Hirshfeld charges are linearly increased to reproduce the experimental dielectric constant of 10 polar solvents having values between 13 (pyridine) and 182 ( N-methylformamide). The OPLS/AA force field is used to obtain the new parameters. The surface tension and liquid density are also target properties to determine the new nonbonding parameters. The charge scaling factor is between 1.2 and 1.3. In addition, properties that were not used in the parametrization procedure, such as the heat of vaporization, self-diffusion coefficient, shear viscosity, isothermal compressibility, and volumetric expansion coefficient are obtained. Binary mixtures of amide/water and amide/amide are also studied. The original parameters of OPLS/AA, CGenFF, and GAFF force fields are evaluated. The TIP4P/epsilon force field is used to simulate water. The results from this work with the new parameters, for both pure components and binary mixtures, are in better agreement with experimental data than those obtained with the original values for most of the calculated properties. The maximum density of N methylformamide in aqueous solutions is correctly predicted only with the new parameters. The high value of the dielectric constant of acetamide, formamide, and N-methylformamide is discussed in terms of the chain formation from the hydrogen bond interactions. PMID- 30278121 TI - Unusually Strong Electrochemiluminescence from Iridium-Based Redox Polymers Immobilized As Thin Layers or Polymer Nanoparticles. AB - A new class of redox metallopolymer based on cyclometalated iridium(III) centers is described, with unusually intense luminescence properties in aqueous media. We report the facile synthesis, photophysical and electrochemical characterization, supported by DFT calculations and their electrochemiluminescence (ECL) properties which, under some circumstances, are significantly greater than the analogous ruthenium-based materials. The photoluminescence (PL) and ECL of these materials are further dramatically enhanced when dispersed or immobilized as polymeric nanoparticles (PNPs). This aggregation-induced emission (AIE and AIECL) operates by providing important protection for the cyclometalated iridium(III) centers against the types of quenching processes which commonly afflict iridium-based luminophores in aqueous media. The results suggest interesting new avenues of research for the application of such materials in and PL and ECL-based detection and imaging as well as light-emitting devices. PMID- 30278122 TI - Direct Electrochemical P(V) to P(III) Reduction of Phosphine Oxide Facilitated by Triaryl Borates. AB - Triaryl borate Lewis acids facilitate the direct two-electron reduction of the P(V) center of triphenylphosphine oxide (TPPO) to the P(III) center of triphenylphosphine at faradaic efficiencies of 37%. Insight from direct P(V) to P(III) reduction is provided from cyclic voltammetry. The electrochemical reduction of TPPO proceeds through an unusual ECrECi mechanism in which the breaking of the phosphoryl bond in a two-electron-reduced association complex with the triaryl borate is rate-determining. The rate and faradaic efficiency for TPPO reduction are tuned by judicious choice of substituents on triaryl borate, with tris(4-methoxyphenyl) borate demonstrating the highest for both. These results suggest that an attractive route toward the room-temperature reduction of phosphate for phosphorus reclamation is greatly facilitated by the stabilization of reduced phosphate intermediates through their association with Lewis acids. PMID- 30278123 TI - Catch and Release Photosensitizers: Combining Dual-Action Ruthenium Complexes with Protease Inactivation for Targeting Invasive Cancers. AB - Dual action agents containing a cysteine protease inhibitor and Ru-based photosensitizer for photodynamic therapy (PDT) were designed, synthesized, and validated in 2D culture and 3D functional imaging assays of triple-negative human breast cancer (TNBC). These combination agents deliver and release Ru-based PDT agents to tumor cells and cause cancer cell death upon irradiation with visible light, while at the same time inactivating cathespin B (CTSB), a cysteine protease strongly associated with invasive and metastatic behavior. In total five Ru-based complexes were synthesized with the formula [Ru(bpy)2(1)](O2CCF3)2 (3), where bpy = 2,2'-bipyridine and 1 = a bipyridine-based epoxysuccinyl inhibitor; [Ru(tpy)(NN)(2)](PF6)2, where tpy = terpiridine, 2 = a pyridine-based epoxysuccinyl inhibitor and NN = 2,2'-bipyridine (4); 6,6'-dimethyl-2,2' bipyridine (5); benzo[ i]dipyrido[3,2- a:2',3'- c]phenazine (6); and 3,6 dimethylbenzo[ i]dipyrido[3,2- a:2',3'- c]phenazine (7). Compound 3 contains a [Ru(bpy)3]2+ fluorophore and was designed to track the subcellular localization of the conjugates, whereas compounds 4-7 were designed to undergo either photoactivated ligand dissociation and/or singlet oxygen generation. Photochemical studies confirmed that complexes 5 and 7 undergo photoactivated ligand dissociation, whereas 6 and 7 generate singlet oxygen. Inhibitors 1-7 all potently and irreversibly inhibit CTSB. Compounds 4-7 were evaluated against MDA MB-231 TNBC and MCF-10A breast epithelial cells in 2D and 3D culture for effects on proteolysis and cell viability under dark and light conditions. Collectively, these data reveal that 4-7 potently inhibit dye-quenched (DQ) collagen degradation, whereas only compound 7 causes efficient cell death under light conditions, consistent with its ability to release a Ru(II)-based photosensitizer and to also generate 1O2. PMID- 30278124 TI - Computation of Dynamic Polarizabilities and van der Waals Coefficients from Path Integral Monte Carlo. AB - We demonstrate computation of total dynamic multipole polarizabilities using path integral Monte Carlo method (PIMC). The PIMC approach enables accurate thermal and nonadiabatic mixing of electronic, rotational, and vibrational degrees of freedom. Therefore, we can study the thermal effects, or lack thereof, in the full multipole spectra of the chosen one- and two-electron systems: H, Ps, He, Ps2, H2, and HD+. We first compute multipole-multipole correlation functions up to octupole order in imaginary time. The real-domain spectral function is then obtained by analytical continuation with the maximum entropy method. In general, sharpness of the active spectra is limited, but the obtained off-resonant polarizabilities are in good agreement with the existing literature. Several weak and strong thermal effects are observed. Furthermore, the polarizabilities of Ps2 and some higher multipole and higher frequency data have not been published before. In addition, we compute isotropic dispersion coefficients C6, C8, and C10 between pairs of species using the simplified Casimir-Polder formulas.

Cassette chromosome recombinases (Ccr) specifically perform excision and acquisition of a staphylococcal cassette chromosome mec (SCC mec) in staphylococci and are responsible for the spread of methicillin resistance. This study explored the roles of CcrC2, a recently discovered Ccr, in the horizontal transfer of SCC mec and developed a potential means to control the spread of methicillin resistance. Knockout of CcrC2 completely aborted the excision of SCC mec, while overexpression of CcrC2 partially removed the SCC mec from the genome and transformed methicillin-resistant Staphylococcus aureus (MRSA) into methicillin susceptible Staphylococcus aureus (MSSA). Moreover, two nucleotide residues (G5C6) in the direct repeat sequence within an att site were found to be critical for excision and acquisition efficiencies. To block the horizontal transfer of methicillin resistance, a SCC mec killer system was developed by combining the CcrC2-mediated SCC mec excision and the mecA-targeting CRISPR-Cas9 machinery. The SCC mec killer transformed MRSA to MSSA and disrupted the mecA-carrying SCC mec intermediate, thereby eliminating methicillin resistance determinant mecA gene inside a MRSA cell and blocking the horizontal transfer of SCC mec. The SCC mec killer was versatile for efficiently removing multiple types of SCC mec elements. It is envisioned that this approach could offer a new means to control the spread of methicillin resistance.

AB - Initial attachment to a surface is a key and highly regulated step in biofilm formation. In this study, we present a platform for reversibly functionalizing bacterial cell surfaces with an emphasis on designing biofilms. We engineered the Lap system of Pseudomonas fluorescens Pf0-1, which is normally used to regulate initial cell surface attachment, to display various protein cargo at the bacterial cell surface and control extracellular release of the cargo in response to changing levels of the second messenger c-di-GMP. To accomplish this goal, we fused the protein cargo between the N-terminal retention module and C-terminal secretion signal of LapA and controlled surface localization of the cargo with natural signals known to stimulate or deplete c-di-GMP levels in P. fluorescens Pf0-1. We show this system can tolerate large cargo in excess of 500 amino acids, direct P. fluorescens Pf0-1 to surfaces it does not typically colonize, and program this microbe to sequester the toxic medal cadmium. PMID- 30278128 TI - FINDSITEcomb2.0: A New Approach for Virtual Ligand Screening of Proteins and Virtual Target Screening of Biomolecules. AB - Computational approaches for predicting protein-ligand interactions can facilitate drug lead discovery and drug target determination. We have previously developed a threading/structural-based approach, FINDSITEcomb, for the virtual ligand screening of proteins that has been extensively experimentally validated. Even when low resolution predicted protein structures are employed, FINDSITEcomb has the advantage of being faster and more accurate than traditional high resolution structure-based docking methods. It also overcomes the limitations of traditional QSAR methods that require a known set of seed ligands that bind to the given protein target. Here, we further improve FINDSITEcomb by enhancing its template ligand selection from the PDB/DrugBank/ChEMBL libraries of known protein ligand interactions by (1) parsing the template proteins and their corresponding binding ligands in the DrugBank and ChEMBL libraries into domains so that the ligands with falsely matched domains to the targets will not be selected as template ligands; (2) applying various thresholds to filter out falsely matched template structures in the structure comparison process and thus their corresponding ligands for template ligand selection. With a sequence identity cutoff of 30% of target to templates and modeled target structures, FINDSITEcomb2.0 is shown to significantly improve upon FINDSITEcomb on the DUD-E benchmark set by increasing the 1% enrichment factor from 16.7 to 22.1, with a p value of 4.3 * 10-3 by the Student t-test. With an 80% sequence identity cutoff of target to templates for the DUD-E set and modeled target structures, FINDSITEcomb2.0, having a 1% ROC enrichment factor of 52.39, also outperforms state-of-the-art methods that employ machine learning such as a deep convolutional neural network, CNN, with an enrichment of 29.65. Thus, FINDSITEcomb2.0 represents a significant improvement in the state-of-the-art.

AB - Due to the Earth's scarcity of lithium, replacing lithium with earth-abundant and low-cost sodium for sodium-ion batteries (SIBs) has recently become a promising substitute for lithium-ion batteries. However, the shortage of appropriate anode materials limits the development of SIBs. Here, a dual-carbon conductive network enhanced GeP5 (GeP5/acetylene black/partially reduced graphene oxide sheets (GeP5/AB/p-rGO)) composite is successfully prepared by a facile ball milling method. The dual-carbon network not only provides more transport pathways for electrons but also relaxes the huge volume change of the electrode material during the charge/discharge process. Compared with only AB- or GO-modified GeP5 (GeP5/AB or GeP5/GO) composite, the GeP5/AB/p-rGO composite shows a superior sodium storage performance with an excellent rate and cycle performance. It delivers a high reversible capacity of 597.5 and 175 mAh/g at the current density of 0.1 and 5.0 A/g, respectively. Furthermore, at the current density of 0.5 A/g, the GeP5/AB/p-rGO composite shows the reversible capacity of 400 mAh/g after 50 cycles with a little capacity attenuation. All above results prove that the GeP5/AB/p-rGO composite has a good prospect of application as an anode material for SIBs.

AB - Iodine monochloride (ICl) elimination from one-photon dissociation of CH2ICl at 248 nm is monitored by cavity ring-down absorption spectroscopy (CRDS). The spectrum of ICl is acquired in the transition of B3Pi0 <- X1Sigma+ and is confirmed to result from a primary photodissociation, that is, CH2ICl + hnu -> CH2 + ICl. The vibrational population ratio is determined with the aid of spectral simulation to be 1:(0.36 +/- 0.10):(0.11 +/- 0.05) for the vibrational levels nu = 0, 1, and 2 in the ground electronic state, corresponding to a Boltzmann-like vibrational temperature of 535 +/- 69 K. The quantum yield of the ICl molecular channel for the reaction is obtained to be 0.052 +/- 0.026 using a relative method in which the scheme CH2Br2 -> CH2 + Br2 is adopted as the reference reaction. The ICl product contributed by the secondary collisions is minimized such that its quantum yield obtained is not overestimated. With the aid of the CCSD(T)//B3LYP/MIDI! level of theory, the ICl elimination from CH2ICl is evaluated to follow three pathways via either (1) a three-center transition state or (2) two isomerization transition states. However, the three-center concerted mechanism is verified to be unfavorable. PMID- 30278129 TI - Modular Pore-Forming Immunotoxins with Caged Cytotoxicity Tailored by Directed Evolution. AB - Immunotoxins are proteins containing a cell-targeting element linked to a toxin that are under investigation for next-generation cancer treatment. However, these agents are difficult to synthesize, chemically heterogeneous, expensive, and show toxicity toward healthy cells. In this work, we describe the synthesis and characterization of a new type of immunotoxin that showed exquisite selectivity toward targeted cells. In our construct, targeting molecules were covalently attached or genetically fused to oligomeric pore-forming toxins. The activity of the immunotoxin was then caged by fusing a soluble protein to the transmembrane domain and activated via cleavage with furin, which is a protease that is overexpressed in many cancer cells. During the several coupling steps, directed evolution allowed the efficient synthesis of the molecules in E. coli cells, as well as selection for further specificity toward targeted cells. The final construct showed no off-target activity, while acquiring an additional degree of specificity toward the targeted cells upon activation. The pore-forming toxins described here do not require internalization to operate, while the many protomeric subunits can be individually modified to refine target specificity. PMID- 30278131 TI - [99mTc][Tc(N)PNP43]-Labeled RGD Peptides As New Probes for a Selective Detection of alphavbeta3 Integrin: Synthesis, Structure-Activity and Pharmacokinetic Studies. AB - New integrin-selective molecules suitable for therapeutic or imaging purposes are currently of interest in development of effective personalized medical platforms. RGDechi is a bifunctional peptide selective for integrin alphavbeta3. Herein, RGDechi and three truncated derivatives functionalized with a cysteine (1-4) were synthesized and labeled with the [99mTc][Tc(N)PNP43]-synthon ([PNP43 = (CH3)2P(CH2)2N(C2H4OCH3)(CH2)2P(CH3)2]) (99mTc1-4) as a basis for selective integrin recognition. The pharmacological parameters of all radiolabeled peptides were assessed along with the pharmacokinetic profiles of the most promising 99mTc1 and 99mTc2 compounds both on healthy and melanoma-bearing mice. Their metabolism and metabolite identification are also reported. 99mTc1-2 are able to discriminate between endogenously expressed integrins alphavbeta3 and alphavbeta5 and possess favorable pharmacokinetics characterized by low liver uptake and rapid elimination from nontarget tissues resulting in positive target-to nontarget ratios. Results are encouraging; the presented construct can be considered the starting point for the development of agents for the selective detection of alphavbeta3 expression by SPECT. PMID- 30278132 TI - Discerning Chemical Pressure amidst Weak Potentials: Vibrational Modes and Dumbbell/Atom Substitution in Intermetallic Aluminides. AB - The space requirements of atoms are generally regarded as key constraints in the structures, reactivity, and physical properties of chemical systems. However, the empirical nature of such considerations renders the elucidation of these size effects with first-principles calculations challenging. DFT-chemical pressure (DFT-CP) analysis, in which the output of DFT calculations is used to construct maps of the local pressures acting between atoms due to lattice constraints, is one productive approach to extracting the role of atomic size in the crystal structures of materials. While in principle this method should be applicable to any system for which DFT is deemed an appropriate treatment, so far it has worked most successfully when semicore electrons are included in the valence set of each atom to supply an explicit repulsive response to compression. In this Article, we address this limiting factor, using as model systems intermetallics based on aluminum, a key component in many structurally interesting phases that is not amenable to modeling with a semicore pseudopotential. Beginning with the Laves phase CaAl2, we illustrate the difficulties of creating a CP scheme that reflects the compound's phonon band structure with the original method due to minimal core responses on the Al atoms. These deficiencies are resolved through a spatial mapping of three energetic terms that were previously treated as homogeneous background effects: the Ewald, Ealpha, and nonlocal pseudopotential components. When charge transfer is factored into the integration scheme, CP schemes consistent with the phonon band structure are obtainable for CaAl2, regardless of whether Ca is modeled with a semicore or valence-only pseudopotential. Finally, we demonstrate the utility of the revised method through its application to the La3Al11 structure, which is shown to soothe CPs that would be encountered in a hypothetical BaAl4-type parent phase through the substitution of selected Al2 pairs with single Al atoms. La3Al11 then emerges as an example of a more general phenomenon, CP-driven substitutions of simple motifs.

AB - High-resolution detection of genome-wide 5-hydroxymethylcytosine (5hmC) sites of small-scale samples remains challenging. Here, we present hmC-CATCH, a bisulfite free, base-resolution method for the genome-wide detection of 5hmC. hmC-CATCH is based on selective 5hmC oxidation, chemical labeling and subsequent C-to-T transition during PCR. Requiring only nanoscale input genomic DNA samples, hmC CATCH enabled us to detect genome-wide hydroxymethylome of human embryonic stem cells in a cost-effective manner. Further application of hmC-CATCH to cell-free DNA (cfDNA) of healthy donors and cancer patients revealed base-resolution hydroxymethylome in the human cfDNA for the first time. We anticipate that our chemical biology approach will find broad applications in hydroxymethylome analysis of limited biological and clinical samples. PMID- 30278134 TI - Dynamics of Dimethylbutanols in Plastic Crystalline Phases by Field Cycling 1H NMR Relaxometry. AB - 2,2-Dimethylbutan-1-ol (2,2-DM-1-B), 3,3-dimethylbutan-1-ol (3,3-DM-1-B), and 3,3 dimethylbutan-2-ol (3,3-DM-2-B) show a rich solid-state polymorphism, which includes one or more plastic crystalline phases (also referred to as orientationally disordered crystalline (ODIC) phases) and glass of the liquid or ODIC phases. In this work, the dynamics of the three isomeric alcohols was investigated in the liquid and plastic crystalline phases by fast field cycling 1H NMR relaxometry in the temperature range between 213 and 303 K. The analysis of the nuclear magnetic relaxation dispersion curves (i.e., longitudinal relaxation rate R1 vs 1H Larmor frequency) acquired for the different alcohols at different temperatures gave quantitative information on internal motions, overall molecular reorientations, and molecular self-diffusion. Self-diffusion coefficients were also determined in the liquid phase and in some ODIC phases of the samples from the trends of 1H R1 as a function of the frequency square root at low frequencies. Remarkable changes in the temperature trends of correlation times and self-diffusion coefficients were found at the transition between the liquid and the ODIC phase for 2,2-DM-1-B and 3,3-DM-1-B, and between ODIC phases for 3,3-DM-2-B, the latter sample showing a markedly different dynamic and phase behavior. PMID- 30278135 TI - Grand Canonical Monte Carlo Simulations on Phase Equilibria of Methane, Carbon Dioxide, and Their Mixture Hydrates. AB - The cage occupancy plays a crucial role in the thermodynamic stability of clathrate hydrates and is an important quantity for understanding the CO2-CH4 replacement phenomenon. In this work, the occupancy isotherms of pure CH4, pure CO2, and their mixture in sI and sII hydrates are studied by GCMC + MD simulations. The adsorption of CH4 and CO2 + CH4 in the sI and sII hydrates can be categorized as the one-site Langmuir type. The calculated occupancy ratio thetaL/thetaS and the abundance ratio of CO2 to CH4 vary with the temperature and pressure, which provide the prerequisite information for the prediction of CH4 recovery yield at different conditions in the CO2-CH4 gas exchange process. The phase equilibria of clathrate hydrates of pure gases and mixtures are explored and the corresponding heat of dissociation and hydration numbers are determined. The current investigation provides new perspectives to understand the mechanism behind the gas adsorption behavior of clathrate hydrates. PMID- 30278136 TI - Electrochemically Triggered Surface Deposition of Polyelectrolytes. AB - An electrochemical approach to surface deposition of polyelectrolytes on self assembled monolayers is presented. This deposition process can be triggered facilely by a potential bias, which oxidizes ferrocene moieties included in the self-assembled monolayer to ferrocenium, whose charge compensation is fulfilled by polyelectrolytes and associated counterions. This approach is quite general, affording quantitative deposition of both polyanions and polycations with a wide range of chemical identities (synthetic polymers, peptides, and DNA) and molecular weights (103-107 Da as tested). Conventional layer-by-layer polyelectrolyte deposition can be straightforwardly combined with this method to produce electroactive polymer films. Several techniques, including voltammetry, fluorescence spectroscopy, contact angle analysis, electrochemical quartz crystal microbalance, and atomic force microscopy, were employed to characterize the deposition processes. A detailed discussion on the involved deposition mechanisms is also presented. PMID- 30278137 TI - Artificial Phospholipids and Their Vesicles. AB - Phospholipids are at the heart and origin of life on this planet. The possibilities in terms of phospholipid self-assembly and biological functions seem limitless. Nonetheless, nature exploits only a small fraction of the available chemical space of phospholipids. Using chemical synthesis, artificial phospholipid structures become accessible, and the study of their biophysics may reveal unprecedented properties. In this article, the recent advances by our work group in the field of chemical lipidology are summarized. The family of diamidophospholipids is discussed in detail from monolayer characterization to the formation of faceted vesicles, culminating in the template-free self-assembly of phospholipid cubes and the possible applications of vesicle origami in modern personalized medicine. PMID- 30278138 TI - Enhanced Charging-Induced Resistance Variations of Nanoporous Gold by Dealloying in Neutral Silver Nitrate Solution. AB - Nanoporous gold (np-Au), produced by dealloying in silver nitrate solution exhibits extraordinary high surface-to-volume ratios of more than 20 m2/g which represents an excellent prerequisite for property tuning by surface charging. Upon electrochemical charging in aqueous KOH solution, the electrical resistance is observed to vary reversibly by up to 88%. The charge coefficient, thus the sensitivity of the resistance toward the imposed charge per mol, is however significantly smaller compared to conventionally prepared np-Au, etched in nitric acid solution. While the strong resistance variation observed in the present work can directly be related to the high charge transfer due to extraordinary fine porosity, the charge coefficients can be understood with regards to the matrix resistance of the respective materials, which is strongly influenced by dealloying residuals. PMID- 30278139 TI - Oxidative Layer-By-Layer Multilayers Based on Metal Coordination: Influence of Intervening Graphene Oxide Layers. AB - Layer-by-layer (LbL) fabricated oxidative multilayers consisting of successive layers of inorganic polyphosphate (PP) and Ce(IV) can electrolessly form thin conducting polymer films on their surface. We describe the effect of substituting every second PP layer in the (PP/Ce) multilayers for graphene oxide (GO) as a means of modifying the structure and mechanical properties of these (GO/Ce/PP/Ce) films and enhancing their growth. Both types of LbL films are based on reversible coordinative bonding between the metal ions and the oxygen-bearing groups in PP and GO, instead of purely electrostatic interactions. The GO incorporation leads to the doubling of the areal mass density and to a dry film thickness close to 300 nm after 4 (GO/Ce/PP/Ce) tetralayers. The film roughness increases significantly with thickness. The (PP/Ce) films are soft materials with approximately equal shear storage and loss moduli, but the incorporation of GO doubles the storage modulus. PP displays a marked terminating layer effect and practically eliminates mechanical losses, making the (GO/Ce/PP/Ce) films almost pure soft elastomers. The smoothness of the (PP/Ce) films and the PP-termination effects are attributed to the reversible coordinative bonding. The (GO/Ce/PP/Ce) films oxidize pyrrole and 3,4-ethylenedioxythiophene (EDOT) and form polypyrrole and PEDOT films on their surfaces. These polymer films are considerably thicker than those formed using the (PP/Ce) multilayers with the same nominal amount of cerium layers. The GO sheets interfere with the polymerization reaction and make its kinetics biphasic. The (GO/Ce) multilayers without PP are brittle and thin.

AB - To create printing substrates for colorimetric sensor arrays, chemically resistant membranes are prepared by coating cellulose filter paper with perfluoroalkoxy (PFA) polymer nanoparticles. A water-based fluorothermoplastic polymer dispersion was diluted with an organic solvent that causes weak aggregation of polymer nanoparticles. The resulting solution improved adhesion between the polymer and the cellulose membrane, providing a more mechanically stable substrate. These PFA polymer-coated substrates demonstrated superior chemical resistance against strong alkalines and had relatively uniform nanoporous structures that substantially improved the printability of a colorimetric sensor array. Finally, colorimetric sensor arrays printed on these substrates were evaluated for the detection of four different toxic industrial chemicals (e.g., ammonia, hydrogen sulfide, nitrogen dioxide, and sulfur dioxide) at or below their permissible exposure limits. PMID- 30278140 TI - Splash-Resistant and Light-Weight Silk-Sheathed Wires for Textile Electronics. AB - Silk has outstanding mechanical properties and biocompatibility. It has been used to fabricate traditional textiles for thousands of years and can be produced in large scale. Silk materials are potentially attractive in modern textile electronics. However, silk is not electrically conductive, thus limiting its applications in electronics. Moreover, regenerated silk is generally rigid and brittle, which hinder post processing. Here we report the fabrication of conductive silk wire in which carbon nanotube (CNT) yarns are wrapped with fluffy and flexible silk nanofiber films. The silk nanofiber film was prepared by electrospinning and then wrapped around a rotating CNT yarn in situ. The obtained silk-sheathed CNT (CNT@Silk) wire has an insulating sheath, which protects the body against electrical shock. In addition, the fabricated wires exhibit a high electrical conductivity (3.1 * 104 S/m), good mechanical strength (16 cN/tex), excellent flexibility, and high durability. More importantly, the wires have an extremely low density (2.0-7.8 * 104 g/m3), which is 2 orders of magnitude lower than that of the traditional metal wire (for example, Cu). Moreover, the wires display a good resistance to humidity, and a simple post treatment can make the wires splash-resistant, thereby expanding its applications. On the basis of these features, we demonstrate the use of the lightweight CNT@Silk wires in smart clothes, including electrochromism and near-field communication.

AB - Forensic entomology aids the determination of post mortem interval based on arthropods associated with a deceased body. This relies on the accurate identification of insects that visit the body, particularly first colonisers such as Calliphoridae (Diptera). Traditional species identification though morphological keys can be challenging as immature or closely related specimens can look similar. Some of these challenges have been overcome through "DNA barcoding", which involves the sequencing of informative regions within a species' DNA and comparison to a database of reference sequences. However, reference DNA sequences of blow fly species in South Africa is currently limited. In this study, adult blow flies representing four species common to the Western Cape, South Africa (Chrysomya chloropyga, Chrysomya albiceps, Chrysomya marginalis, Lucilia sericata) were examined using morphological keys and DNA barcoding of two regions: COI and ITS2. These DNA sequences were then used as references for the successful identification of seven unknown immature specimens. Intraspecific divergence showed a maximum of 0.36% and 2.25% for COI and ITS2, respectively; interspecific divergence showed a minimum of 6.14% and 64.6% for COI and ITS2, respectively. According to these results, COI and ITS2 have sufficient discriminatory power for species-level identification for the four species studied.

PMID- 30278148 TI - Considerations for incorporating real-time PCR assays into routine marine biosecurity surveillance programmes: a case study targeting the Mediterranean fanworm (Sabella spallanzanii) and club tunicate (Styela clava). AB - Molecular techniques may provide effective tools to enhance marine biosecurity surveillance. Prior to routine implementation, evidence-based consideration of their benefits and limitations is needed. In this study, we assessed the efficiency and practicality of visual diver surveys and real-time PCR assays (targeting DNA and RNA) for detecting two marine invasive species whose infestation levels varied between species and location: Sabella spallanzanii and Styela clava. Filtered water samples (n = 171) were collected in parallel with dive surveys at two locations as part of the New Zealand Marine High Risk Site Surveillance programme: Nelson Harbour (27 sites) and Waitemata Harbour (30 sites). Diver surveys resulted in a greater number of detections compared to real time PCR: S. clava - 21 versus 5 sites in Nelson, 6 versus 1 in Auckland; S. spallanzanii - 18 versus 10 in Auckland, no detections in Nelson. Occupancy modelling derived detection probabilities for the real-time PCR for S. clava were low (14%), compared to S. spallanzanii (66%). This could be related to abundances, or species-specific differences in DNA shedding. Only one RNA sample was positive, suggesting that most detections were from extracellular DNA or non viable fragments. While molecular methods cannot yet replace visual observations, this study shows they provide useful complementary information. PMID- 30278147 TI - Characterization and comparison of poorly known moth communities through DNA barcoding in two Afrotropical environments in Gabon. AB - Biodiversity research in tropical ecosystems-popularized as the most biodiverse habitats on Earth-often neglects invertebrates, yet invertebrates represent the bulk of local species richness. Insect communities in particular remain strongly impeded by both Linnaean and Wallacean shortfalls, and identifying species often remains a formidable challenge inhibiting the use of these organisms as indicators for ecological and conservation studies. Here we use DNA barcoding as an alternative to the traditional taxonomic approach for characterizing and comparing the diversity of moth communities in two different ecosystems in Gabon. Though sampling remains very incomplete, as evidenced by the high proportion (59%) of species represented by singletons, our results reveal an outstanding diversity. With about 3500 specimens sequenced and representing 1385 BINs (Barcode Index Numbers, used as a proxy to species) in 23 families, the diversity of moths in the two sites sampled is higher than the current number of species listed for the entire country, highlighting the huge gap in biodiversity knowledge for this country. Both seasonal and spatial turnovers are strikingly high (18.3% of BINs shared between seasons, and 13.3% between sites) and draw attention to the need to account for these when running regional surveys. Our results also highlight the richness and singularity of savannah environments and emphasize the status of Central African ecosystems as hotspots of biodiversity.

AB - The aim of this study was to examine the interaction of [Pd(2,2'-bipyridine) (morpholinedithiocarbamate)]NO3 and [Pt (2,2' bipyridine)(morpholinedithiocarbamate)]NO3 with human serum albumin under physiological conditions by using fluorescence, absorption, and circular dichroism spectroscopic techniques. Spectroscopic analysis of the emission quenching at different temperatures demonstrated that the quenching mechanism was static quenching. From the circular dichroism results, thermal stability study, it was found that the interaction of the complexes with human serum albumin caused a conformational change of the protein reversibly. These 2 anticancer Pd and Pt complexes were activated against chronic myelogenous leukemia cell line K562, so that 50% cytotoxic concentration values of 16 and 26 MUM for Pd and Pt complexes, respectively, were observed, which were much lower than that of cisplatin (154 MUM). Biological activities of both Pd and Pt complexes were also assayed against selective microorganisms by the disc diffusion method. These results showed that the Pd(II) complex is antifungal agent but Pt(II) complex has antibacterial activity. Also, the interaction of both metal derivative complexes was studied by molecular docking. Complementary molecular docking results may be useful to determine the binding mechanism of human serum albumin in pharmaceutical and biophysical studies providing new insight in the novel pharmacology.

PMID- 30278153 TI - Striving to Meet Healthy People 2020 Objectives: Trend Analysis of Maternal Smoking. AB - OBJECTIVES:: We examined trends in prevalence rates of smoking and smoking cessation during pregnancy among women in the United States to assess achievement of Healthy People 2020 prevention targets. METHODS:: We assessed the smoking habits of 30 667 mothers whose children were born between 1985 and 2014 and who were sampled by the National Health and Nutrition Examination Survey, 1999-2014. Sampled participants were children aged 0-15 at the time of interview; however, an adult proxy-usually the biological mother-responded on the child's behalf and reported information about maternal tobacco use during pregnancy. We calculated prevalence rates, adjusted odds ratios (aORs), and predicted annual increase or decrease of smoking and quitting smoking during pregnancy, adjusting for mother's age at delivery and income level and child's race/ethnicity and sex. RESULTS:: The average annual prevalence of smoking at any time during pregnancy decreased from 25.7% (95% confidence interval [CI], 15.3%-36.0%) in 1985 to 10.1% (95% CI, 7.1%-13.0%) in 2014 ( P < .001), and quitting smoking at any time during the index pregnancy increased from 36.6% (95% CI, 20.3%-52.9%) in 1985 to 54.9% (95% CI, 44.4%-65.4%) in 2008 ( P = .002). The adjusted annual risk of smoking during pregnancy decreased significantly by 3% (aOR = 0.97; 95% CI, 0.95-0.98; P < .001). The prevalence rate of smoking in the year 2020 extrapolated from the current trend would be 6.1%. CONCLUSIONS:: Smoking during pregnancy in the United States is declining. However, renewed public health measures are needed to achieve the Healthy People 2020 objectives of preventing smoking among pregnant women in the United States. PMID- 30278154 TI - Molecular characterization of human echinococcosis in Sichuan, Western China. AB - Cystic echinococcosis (CE) and alveolar echinococcosis (AE) are highly co-endemic in Sichuan, a part of Qinghai-Tibet Plateau where is a typical Tibetan nomadic community living area. In order to better understand the Echinococcus spp. of human being infected origins in this area, 140 lesions were collected from echinococcosis patients who were received operations during the period of 2014 2016 in different geographic districts in this region. Partial DNA sequences of the mitochondrial cox1 gene were analyzed. The genetic characterization of the isolates from 3 different places including Ganzi, Aba and Liangshan were assessed. Of all the 140 samples, the great majority was identified as Echinococcus granulosus sensu stricto (n = 108). Echinococcus multilocularis was confirmed to be another important pathogen of the human infections (n = 31). Additionally, one Echinococcus canadensis (G6/7) isolate from Ganzi was confirmed. Comparing the clinical diagnosis with the sequencing results, 6.4% (9/140) of the cases were misdiagnosed between AE and CE, and another 8.6% (12/140) were unclassified to sub-type in echinococcosis. Higher rates of misdiagnosis and unclassified diagnosis were found in AE cases (12.9%, 4/31 and 16.1%, 5/31 respectively) compared to CE (4.6%, 5/109 and 6.4%, 7/109 respectively). In E.granulosus s.s., a total of 34 haplotypes were detected, and 4 haplotypes were inferred from E.multilocularis. The haplotype networks of the 2 species exhibited a similar star-shaped feature with a dominant haplotype in the center. Geographically specific haplotypes were observed in Ganzi and Aba respectively. This study provides insight into the current species causing human echinococcosis in the Tibetan districts of Sichuan. E.granulosus s.s. and E.multilocularis are confirmed to be the main causative agents, and the existence of E.canadensis (G6/7) is also observed in the region. Molecular diagnosis was proven to be essential for the confirmation of human echinococcosis in the area. PMID- 30278155 TI - A novel solution phase PAI-1/uPA-biotin complex assay for the measurement of active PAI-1 in plasma. AB - We devised a new assay procedure to use biotinylated uPA to trace the active PAI 1 levels in the plasma. We show here that the potency of inhibitory monoclonal antibody 33B8 measured with the new assay is consistent with its in vivo efficacy in PAI-1 inactivation. We also found that among the three monoclonal antibodies tested, the traditional solid phase assay caused mechanism dependent significant right shift of IC50 values. As our new assay avoids the use of non-physiological large quantities of uPA, we conclude that it is a better measure of pharmacodynamic effects of anti-PAI-1 antibodies in vivo. PMID- 30278156 TI - Regulation of cardiac calcium by mechanotransduction: Role of mitochondria. AB - Myocardium is subjected to a variety of forces with each contraction, such as stretch, afterload, and shear stress, and adapts to those mechanical stimuli. These mechanical stimuli increase in heart failure, valvular heart disease and hypertension that are clinically associated with arrhythmia and myocyte remodeling. To understand cellular and molecular basis of mechanical stress mediated cardiac dysfunction and remodeling, several experimental approaches have been successfully used in single cardiac myocytes. In this review, we will briefly summarize the current knowledge about the responses of cardiac myocytes to mechanical stimuli and underlying mechanisms in the context of Ca2+ signaling, with focusing on the role of mitochondria in these mechanotransductions. Recent evidence suggests that mechanotransduction, associated with mitochondrial metabolism, significantly alters Ca2+ signaling and ionic homeostasis in cardiac myocytes under shear stress or prolonged stretch, and that it may play a key role in the pathogenesis of heart failure. PMID- 30278157 TI - Detection of cholesterol bilayer domains in intact biological membranes: Methodology development and its application to studies of eye lens fiber cell plasma membranes. AB - Four purported lipid domains are expected in plasma membranes of the eye lens fiber cells. Three of these domains, namely, bulk, boundary, and trapped lipids, have been detected. The cholesterol bilayer domain (CBD), which has been detected in lens lipid membranes prepared from the total lipids extracted from fiber cell plasma membranes, has not yet been detected in intact fiber cell plasma membranes. Here, a saturation-recovery electron paramagnetic resonance spin labeling method has been developed that allows identification of CBDs in intact fiber cell plasma membranes of eye lenses. This method is based on saturation recovery signal measurements of the cholesterol-analog spin label located in the lipid bilayer portion of intact fiber cell membranes as a function of the partial pressure of molecular oxygen with which the samples are equilibrated. The capabilities and limitations of this method are illustrated for intact cortical and nuclear fiber cell plasma membranes from porcine eye lenses where CBDs were detected in porcine nuclear intact membranes for which CBDs were also detected in lens lipid membranes. CBDs were not detected in porcine cortical intact and lens lipid membranes. CBDs were detected in intact membranes isolated from both cortical and nuclear fiber cells of lenses obtained from human donors. The cholesterol content in fiber cell membranes of these donors was always high enough to induce the formation of CBDs in cortical as well as nuclear lens lipid membranes. The results obtained for intact membranes, when combined with those obtained for lens lipid membranes, advance our understanding of the role of high cholesterol content and CBDs in lens biology, aging, and/or cataract formation.

AB - OBJECTIVE: To develop a mobile health app for older women with HIV infection that will be used in a larger study. DESIGN: A qualitative study design. SETTING: Baltimore-Washington metropolitan area clinics and communities. PARTICIPANTS: Ten women 50 years and older (mean age = 62.8 years, standard deviation = 3.62, range = 58-69 years) who self-identified as Black or African American and were infected with HIV. METHODS: At the start of the study, we used relevant empirical and the self-determination theory to inform the draft Web-based app content that was shared with two focus groups. Data were analyzed with input from a community advisory board (CAB) to inform the development of the mobile health app. RESULTS: We inductively identified eight subthemes within the coding structure of two overall themes: Navigating Content, Functions, and Features and Enhancing Provider Interaction With Patients that represented the perspectives of participants regarding the app. From the eight subthemes, we integrated the contributions from the CAB, which we then used to further optimize the app. CONCLUSION: The app was designed to provide support, tools, and resources for older women with HIV. Engagement of community collaborators could be challenging because of multiple personal and structural barriers. Nonetheless, the potential community member benefits are invaluable. If successful, the Web-based app could be a model to address the needs of older persons with HIV infection. PMID- 30278159 TI - Auckland Cataract Study III: refining preoperative assessment with cataract risk stratification to reduce intraoperative complications. AB - PURPOSE: To assess intraoperative complications of phacoemulsification surgery in public teaching hospital settings using modified preoperative risk stratification systems. DESIGN: Prospective cohort study. METHODS: Preoperative risk stratification of 500 consecutive cataract cases using the New Zealand Cataract Risk Stratification (NZCRS) scoring system. Recommended allocation of higher-risk phacoemulsification procedures to experienced surgeons in public teaching hospital setting. Main outcome measure; intraoperative complications relative to adherence to stratification recommendations. RESULTS: NZCRS classified 192 cases (38%) as high-risk, recommended for Fellows or Consultants (Attendings). Primary surgeons: Residents (n=142, 28%), Fellows (n=88, 18%), Consultants (n=270, 54%). Overall rate (N=500) of any intraoperative complication was 5.0%. Where NZCRS scoring recommendations were observed (n=448) the intraoperative complication rate was 4.5% but in 'non-adherence' cases (n=52, Residents operating on higher risk cases) this nearly doubled (9.6%). Postoperative complications occurred in 5.2%, primarily cystoid macular oedema (3.7%). Postoperatively, mean unaided visual acuity was 6/12 (20/40) and best-corrected visual acuity improved from 6/20 (20/63) preoperatively to 6/10 (20/32) postoperatively (p<0.05). CONCLUSIONS: The NZCRS system aids identification of higher-risk cataract cases, appropriate case-to-surgeon allocation, and may increase surgeon awareness of risk factors. Compared to two previous studies under similar conditions in the same institution, the NZCRS system was associated with a 40% reduction in intraoperative complications (8.4% to 5%). The rate of posterior capsular tear was 0.6% (p= .035) compared to 2.6% in baseline phase and 1.4% in a prior risk stratification phase. Risk-stratification appears to reduce intraoperative phacoemulsification complications in public teaching hospital settings. PMID- 30278160 TI - Clinical and ophthalmic factors associated with the severity of sickle cell retinopathy. AB - PURPOSE: To identify associations between severity of sickle cell retinopathy (SCR) and other clinical, laboratory, or treatment factors relevant to sickle cell disease (SCD). DESIGN: Retrospective cohort study. METHODS: We investigated clinical, laboratory, and demographic associations with the severity of SCR in 296 patients seen at both our SCD specialty clinic and our retina clinic. Multivariate multinomial logistic regression was used to estimate the association between each clinical variable and severity of SCR. RESULTS: Multivariate analysis showed that in patients with sickle cell anemia (SCA) genotypes, older age (95% confidence interval [CI], 1.04-1.15; P<0.001) and male gender (95% CI, 0.13-0.87; P=0.02), were associated with proliferative sickle cell retinopathy (PSR). In patients with genotypic variants, visual symptoms (95% CI, 1.36-21.62; P=0.02) were associated with PSR. Laser photocoagulation and vitrectomy surgery, the standard interventions for PSR, were associated with older age (95% CI, 1.05 1.13; P<0.001), visual symptoms (95% CI, 1.48-7.40; P=0.004), higher hemoglobin level (95% CI, 1.14-1.65; P=0.001), and no chronic transfusion (95% CI, 0.16 1.09; P=0.08) across the whole cohort. CONCLUSIONS: These findings may inform clinicians of the symptoms, systemic findings, and disease modifying therapies most frequently associated with SCR in SCD patients. Visual symptoms such as blurred vision or floaters were associated with progression of SCR, and may be criteria for referral for retinal examination. Chronic transfusion therapy may be protective against the need for retinal laser photocoagulation or vitrectomy. Prospective studies are necessary to further explore risk factors for SCR and to identify which individuals with SCD are at risk for incident or progression of retinopathy. PMID- 30278161 TI - New insights into molecular mechanisms of rosiglitazone in monotherapy or combination therapy against cancers. AB - Rosiglitazone (ROSI), a member of thiazolidinediones (TZDs) which act as high affinity agonists of the nuclear receptor peroxisome-proliferator-activated receptor-gamma (PPARgamma), is clinically used as an antidiabetic drug which could attenuate the insulin resistance associated with obesity, hypertension, and impaired glucose tolerance in humans. However, recent studies reported that ROSI had significant anticancer effects on various human malignant tumor cells. Mounting evidence indicated that ROSI could exert anticancer effects through PPARgamma-dependent or PPARgamma-independent ways. In this review, we summarized the PPARgamma-dependent antitumor activities of ROSI, which included apoptosis induction, inhibition of cell proliferation and cancer metastasis, reversion of multidrug resistance, reduction of immune suppression, autophagy induction, and antiangiogenesis; and the PPARgamma-independent antitumor activities of ROSI, which included inhibition of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappaB) pathway, inhibition of prostaglandin E2 (PGE2), increasing MAPK phosphatase 1 (MKP-1) expression and regulation of other apoptosis-related cell factors. In addition, we discussed the anti-cancer application of ROSI by monotherapy or combination therapy with present chemotherapeutic drugs in vitro and in vivo. Moreover, we reviewed the phase I cancer clinical trials related to ROSI combined with chemotherapeutics and phase II trials about the anti-cancer effects of ROSI monotherapy and the radiotherapy sensitivity of ROSI. PMID- 30278162 TI - Mechanistic studies on the effect of membrane lipid acyl chain composition on daptomycin pore formation. AB - Daptomycin is a lipopeptide antibiotic that binds and permeabilizes the cell membranes of Gram-positive bacteria. Membrane permeabilization requires both calcium and phosphatidylglycerol (PG) in the target membrane, and it correlates with the formation of an oligomer that likely comprises eight subunits, which are evenly distributed between the two membrane leaflets. In both bacterial cells and model membranes, changes in the fatty acyl composition of the membrane phospholipids can prevent permeabilization. We here used liposomes to study the effect of phospholipids containing oleoyl and other fatty acyl residues on daptomycin activity, and made the following observations: (1) Oleic acid residues inhibited permeabilization when part not only of PG, but also of other phospholipids (PC or cardiolipin). (2) When included in an otherwise daptomycin susceptible lipid mixture, even 10% of dioleoyl lipid (DOPC) can strongly inhibit permeabilization. (3) The inhibitory effect of fatty acyl residues appears to correlate more with their chain length than with unsaturation. (4) Under all conditions tested, permeabilization coincided with octamer formation, whereas tetramers were observed on membranes that were not permeabilized. Overall, our findings further support the notion that the octamer is indeed the functional transmembrane pore, and that fatty acyl residues may prevent pore formation by preventing the alignment of tetramers across the two membrane leaflets. PMID- 30278163 TI - 3-dimensional printed models-guided surgical repair for recurrent coronary artery fistula. AB - Recurrent coronary artery fistula is rare and can be difficult for surgical treatment because of anatomic complexity. Here, we reported one case of successful re-repair of a recurrent coronary artery fistula, which added evidence of the 3-dimensional printed models guiding surgical correction of complex intracardiac abnormalities. PMID- 30278164 TI - Video Assisted Thoracoscopic Lobectomy for Lung Cancer. AB - The use of video assisted thoracoscopic surgery (VATS) lobectomy has become a mainstay of modern day thoracic oncology practice and the technique of choice for resection of early stage lung cancers at many institutions. The feasibility of VATS lobectomy has long been well established and there is considerable belief that it leads to better patient outcomes. In the following review, we seek to summarize the current experience with VATS lobectomy, identify the strengths and weaknesses of the available literature and address future areas of research for our field. PMID- 30278165 TI - Neoadjuvant Therapy for Locally Advanced Esophageal Cancer Should Be Targeted to Tumor Histology. AB - BACKGROUND: Controversy exists over the optimal neoadjuvant therapy in patients with locally advanced esophageal cancer (EC). Although most groups favor neoadjuvant chemoradiation (nCRT), some prefer preoperative chemotherapy (nCT) without radiation. The objective of this study was to compare outcomes in EC patients undergoing either regimen, followed by surgery. METHODS: We reviewed a prospectively collected database of EC patients undergoing esophagectomy after nCT or nCRT from 1989 to 2016. Choice of therapy was at the discretion of the multidisciplinary team. Disease-free survival (DFS) and cancer-specific survival (CSS) were compared by the Kaplan-Meier log-rank test. Independent predictors of CSS were estimated by Cox regression analysis. RESULTS: Among 700 EC patients 338 patients were treated with nCRT (n = 112) or nCT (n = 226) followed by surgery. Patients were well matched for age, gender, and clinical stage, although patients with squamous cell carcinoma were more likely to receive nCRT (49% vs 26%, p < 0.001). At surgery 90% and 91% of nCRT and nCT patients, respectively, underwent transthoracic esophagectomy. nCRT, in comparison with nCT, was associated with similar rates of Calvien-Dindo grade III/IV complications (34% vs 33%, p = 0.423) but with a trend toward higher perioperative mortality (5% vs 1%, p = 0.064). Among adenocarcinoma patients (n = 239) the use of nCRT was associated with higher rates of complete clinical response (18% vs 7.4%), pathologically negative lymph nodes (52% vs 30%, p = 0.001), and complete pathologic response (21% vs 5.1%, p < 0.001). However, there was no difference between nCRT and nCT for 5 year DFS (28% vs 31%, p = 0.636) or CSS (51% vs 52%, p = 0.824) among adenocarcinoma patients. For patients with squamous cell carcinoma (n = 98), nCRT and nCT had similar rates of complete clinical response (31% vs 26%, p = 0.205), but the rates of negative nodes (65% vs 46%, p = 0.064) and of complete pathologic response (42% vs 12%, p < 0.05) were higher with nCRT. For these patients nCRT was associated with no statistical difference in 5-year DFS (57% vs 40%, p = 0.595) but with improved 5-year CSS (87% vs 68%, p = 0.019) compared with nCT. On multivariable analysis for CSS, nCRT predicted improved survival for patients with squamous cell carcinoma (hazard ratio, 0.242; 95% confidence interval, 0.071-0.830) but not for those with adenocarcinoma (univariate hazard ratio, 0.940; 95% confidence interval, 0.544-1.623). CONCLUSIONS: For adenocarcinoma patients undergoing surgery for EC, nCRT leads to increased local tumor response compared with nCT alone but with no difference in survival. For squamous carcinoma patients nCRT appears to improve CSS compared with nCT. For patients with locally advanced EC targeted neoadjuvant regimens should be used depending on tumor histology.

PMID- 30278167 TI - Standardized Haller and Asymmetry Index Combined for a More Accurate Assessment of Pectus Excavatum. AB - BACKGROUND: The measurement of the Haller index (HI) is not standardized, and HI does not consider the asymmetry of pectus excavatum. The aim of this study was to determine the most appropriate level for measuring the HI and to introduce the asymmetry index (AI) in order to respect the aspect of asymmetry. METHODS: Preoperative computer tomography scans of 43 patients with pectus excavatum were retrospectively analyzed by measuring both the HI and the AI at 3 different levels: (I) sternomanubrial junction; (II) caudal end of corpus sterni; and (III) tip of the xiphoid. The control group comprised 33 patients without chest wall deformity and a HI < 3.25. For each patient HI and AI were calculated according to a standardized protocol. A McNemar test was used for statistical analyses. RESULTS: The sensitivity of the HI was highest when measured at level II (p < 0.388), and the AI exhibited the highest sensitivity at level I. When combining both indices, the sensitivity of assessing pectus excavatum significantly increased compared with the use of HI at level II alone (p < 0.002). CONCLUSIONS: The measurement of the HI at level II represents the most valid standardized parameter for assessment of the severity of pectus excavatum. Asymmetry, on the other hand, is best assessed by the AI measured at level I. The combination of the standardized HI and AI not only provides a much more accurate description of pectus excavatum, but also improves the comparability of pectus excavatum patients in general. PMID- 30278168 TI - Inhibition of MicroRNA-204 Conducts Neuroprotection Against Spinal Cord Ischemia. AB - BACKGROUND: MicroRNA(miR)-204 is an autophagy- and apoptosis-related gene. Neuroprotection by the inhibition of miR-204 against spinal cord ischemia was evaluated, and the roles of neuronal autophagy and apoptosis were investigated. METHODS: Spinal cord ischemia was conducted in rats by cross-clamping the descending aorta for 14 minutes. Inhibition of miR-204 was induced by intrathecal injection of lentivirus vectors containing antagomiR-204. Hind-limb motor function was assessed with the motor deficit index. Lumbar spinal cords were harvested for histologic examinations and terminal deoxynucleotidyl transferase mediated dUTP-biotin nick-end labeling staining. Autophagy was evaluated by the LC3-II/LC3-I ratio and beclin-1 expression. Expressions of LC3-I, LC3-II, beclin 1, B-cell lymphoma-2 (BCL-2), caspase-3, and miR-204 were measured by Western blot and quantitative real-time polymerase chain reaction. Autophagy was blocked by 3-methyladenine. RESULTS: Transient ischemia enhanced miR-204 expression and the LC3-II/LC3-I ratio and downregulated BCL-2 expression in spinal cords in a time-dependent manner. AntagomiR-204 significantly reduced expressions of miR-204 and caspase-3, dramatically upregulated expressions of beclin-1 and BCL-2 and the LC3-II/LC3-I ratio in spinal cords after reperfusion. Compared with controls, inhibition of miR-204 markedly decreased the motor deficit index scores at 6, 12, 24, and 48 hours after reperfusion; increased the number of viable motor neurons; and decreased the number of apoptotic neurons. 3-Methyladenine completely abolished enhancements of the LC3-II/LC3-I ratio and beclin-1 expression induced by antagomiR-204 and inhibited the protective effect on hind-limb motor function. CONCLUSIONS: Inhibition of miR-204 exerts spinal cord protection against ischemia reperfusion injury, possibly via promotion of autophagy and antiapoptotic effects. PMID- 30278169 TI - Anomalous origin of left pulmonary artery from the aorta: a rare entity in congenital heart disease. AB - Anomalous origin of the left pulmonary artery (ALPA) from the aorta is a rare form of congenital heart disease, leading to long-term morbidity if not treated early. There is a reported association of this anomaly with 22q11 microdeletion syndrome. Surgical repair is commonly via direct reimplantation to the main pulmonary artery with or without patch or flap techniques. We present two unique cases of ALPA describing embryologic considerations for morphogenesis of ALPA with 22q11 microdeletion syndrome and a novel surgical technique involving unroofing of the unique anatomy of the common wall between the LPA and main pulmonary artery. PMID- 30278170 TI - Left Atrial Decompression Via Minithoracotomy During Extracorporeal Life Support. AB - Extracorporeal membrane oxygenation via cervical cannulation is an established option for pediatric patients with acute cardiopulmonary failure. However, left heart decompression is sometimes mandatory in patients with severe left ventricular dysfunction. We describe a fast and less invasive technique for placing a left atrial cannula through a left anterior minithoracotomy approach. In 4 critically ill children, this minimally invasive technique provided satisfactory left heart decompression, and we describe a representative case. PMID- 30278171 TI - Is There a Role for Cancer-Directed Surgery in Early-Stage Sarcomatoid or Biphasic Mesothelioma? AB - BACKGROUND: Benefits of surgical resection for early-stage nonepithelioid malignant pleural mesothelioma (MPM) have not been clearly elucidated. This study investigated whether cancer-directed surgery affects overall survival compared with nonsurgical therapies for T1-T2 N0 M0 sarcomatoid or biphasic MPM patients. METHODS: Adult patients with clinical stage I or II MPM were identified in the National Cancer Database from 2004 to 2103. Patients who underwent cancer directed surgery were matched by propensity score with patients who had received chemotherapy/radiotherapy or no treatments. Overall survival was compared using a Cox proportional hazard regression model. RESULTS: From National Cancer Database queries, 878 patients with clinical stage I or II MPM with sarcomatoid (n = 524) or biphasic (n = 354) histology were identified. Overall median survival was 5.5 months for patients with sarcomatoid mesothelioma. The cancer-directed surgery improved overall survival compared with no operation (median survival, 7.56 months vs 4.21 months, respectively; p < 0.01). In the biphasic group, median overall survival was 12.2 months. Again, the cancer-directed surgery improved survival compared with no operation (15.8 months vs 9.3 months, p < 0.01). For both histologies, the cancer-directed surgery improved overall survival compared with those who underwent chemotherapy or radiotherapy, or both, without resection (p < 0.05). Perioperative mortality was 6.0% at 30 days and 21.4% at 90 days. CONCLUSIONS: The cancer-directed surgery is associated with improved survival in early-stage MPM patients with nonepithelioid histology compared with those who did not undergo resection or chose medical therapy. Given the high perioperative mortality, a careful patient selection and multidisciplinary evaluation is recommended. PMID- 30278172 TI - Gross and histologic relationships of the retropubic urethra to lateral pelvic sidewall and anterior vaginal wall in female cadavers: clinical applications to retropubic surgery. AB - BACKGROUND: Knowledge of the retropubic space anatomy is essential for safe entry and surgical applications within this space. OBJECTIVE: The objectives of this study were to examine the gross and histologic anatomy of the retropubic urethra, paraurethral tissue, and urethrovaginal space and to correlate findings to retropubic procedures. STUDY DESIGN: Anatomic relationships of the retropubic urethra were examined grossly in unembalmed female cadavers. Measured distances included: lateral urethral wall to arcus tendineus fascia pelvis at the level of urethrovesical junction and at 1 cm distal. Other measurements included retropubic urethral length and distances from internal urethral opening to each ureteric orifice. Microscopic examination was performed at the same levels examined grossly in separate nulliparous specimens. Descriptive statistics were used for data analyses. RESULTS: In all, 25 cadavers were examined grossly. Median distance from lateral urethral wall to arcus tendineus fascia pelvis at the level of urethrovesical junction was 25 mm (range, 13-38 mm). At 1 cm distal, the median distance from aforementioned structures was 14 mm (10-26 mm). Median length of the retropubic urethra was 23 mm (range 15-30 mm). Four nulliparous specimens, ages 12 weeks, and 34, 47, and 52 years, were examined histologically. No histologic evidence of a discrete fascial layer between bladder/urethra and anterior vagina was noted at any level examined. Tissue between the urethra and the pelvic sidewall skeletal muscle was composed of dense fibrous tissue, smooth muscle bundles, scant adipose tissue, blood vessels, and nerves. The smooth muscle fibers of the vaginal muscularis interdigitated with skeletal muscle fibers in the pelvic sidewall at both levels examined. No histologic evidence of "pubourethral ligaments" within the paraurethral tissue was noticed. CONCLUSION: A 2-cm "zone of safety" exists between the urethra and arcus tendineus fascia pelvis at the urethrovesical junction level. Suture or graft placement within this region should minimize injury to the urethra, pelvic sidewall muscles, and bladder. Knowledge that the shortest length of retropubic urethra was 1.5 cm and shortest urethra to arcus tendineus fascia pelvis distance was 1 cm highlights the importance of maintaining dissection and trocar entry site close to pubic bone to avoid bladder and/or urethral injury. Histologic analysis of paraurethral tissue supports the nonexistence of pubourethral ligaments. PMID- 30278173 TI - The clinical heterogeneity of preeclampsia is related to both placental gene expression and placental histopathology. AB - BACKGROUND: Preeclampsia is a life-threatening disorder of pregnancy, demonstrating a high degree of heterogeneity in clinical features such as presentation, disease severity, and outcomes. This heterogeneity suggests distinct pathophysiological mechanisms may be driving the placental disease underlying this disorder. Our group recently reported distinct clusters of placental gene expression in preeclampsia and control pregnancies, allowing for the identification of at least 3 clinically relevant gene expression-based subtypes of preeclampsia. Histopathological examination of a small number of samples from 2 of the gene expression-based subtypes revealed placental lesions consistent with their gene expression phenotype, suggesting that detailed placental histopathology may provide further insight into the pathophysiology underlying these distinct gene expression-based subtypes. OBJECTIVES: The objective of the study was to assess histopathological lesions in the placentas of patients belonging to each identified gene expression-based subtype of preeclampsia, characterized in our previous study. Our goal was to further understand the pathophysiologies defining these gene expression-based subtypes by integrating gene expression with histopathological findings, possibly identifying additional subgroups of preeclampsia patients. STUDY DESIGN: Paraffin-embedded placental biopsies from patients included in the gene expression profiling study (n = 142 of 157, 90.4%) were sectioned, hematoxylin and eosin stained, and imaged. An experienced perinatal pathologist, blinded to gene expression findings and clinical information, assessed the presence and severity of histological lesions using a comprehensive, standardized data collection form. The frequency and severity scores of observed histopathological lesions were compared among gene expression-based subtypes as well as within each subtype using using Fisher exact tests, Kruskal-Wallis tests, and hierarchical clustering. The histological findings of the placental samples were visualized using t-distributed stochastic neighbor embedding and phylogenetic trees. Concordance and discordance between gene expression findings and histopathology were also investigated and visualized using principal component analysis. RESULTS: Several histological lesions were found to be characteristic of each gene expression-based preeclampsia subtype. The overall concordance between gene expression and histopathology for all samples was 65% (93 of 142), with characteristic placental lesions for each gene expression-based subtype complementing prior gene enrichment findings (ie, placentas with enrichment of hypoxia-associated genes showed severe lesions of maternal vascular malperfusion). Concordant samples were located in the central area of each gene expression-based cluster when viewed on a principal component analysis plot. Interestingly, discordant samples (gene expression and histopathology not reflective of one another) were generally found to lie at the periphery of the gene expression-based clusters and tended to border the group of patients with phenotypically similar histopathology. CONCLUSION: Our findings demonstrates a high degree of concordance between placental lesions and gene expression across subtypes of preeclampsia. Additionally, novel integrative analysis of scored placental histopathology severity and gene expression findings allowed for the identification of patients with intermediate phenotypes of preeclampsia not apparent through gene expression profiling alone. Future investigations should examine the temporal relationship between these 2 modalities as well as consider the maternal and fetal contributions to these subtypes of disease. PMID- 30278174 TI - National mosaic embryo transfer practices: a survey. AB - BACKGROUND: The growing use of preimplantation genetic testing with in vitro fertilization has provided clinicians with more information about the genetics of embryos. Embryos, however, sometimes result with a mixed composition of both aneuploid and euploid cells, called mosaic embryos. The interpretation of these results has varied, leading some clinicians to transfer mosaic embryos and some opt not to. In addition, laboratories providing preimplantation genetic testing for aneuploidy have differing thresholds for determining an embryo aneuploid, mosaic, or euploid. Overall practice patterns for mosaic embryo transfer practices in the United States are unknown. OBJECTIVE(S): The objectives of the study were to characterize national mosaic embryo transfer practices, including the use of preimplantation genetic testing for aneuploidy, prior history of transferring mosaic embryos, thresholds for determining mosaicism, and willingness to transfer mosaic embryos among assisted reproductive technology clinics in the United States. STUDY DESIGN: A 14 question online survey assessing current use of preimplantation genetic testing for aneuploidy, thresholds for determining mosaicism, and clinic experience and willingness to transfer mosaic embryos was e-mailed to 405 assisted reproductive technology clinics across the United States. Descriptive statistics and logistic regression were used to analyze survey responses and identify clinical factors associated with reporting having ever transferred a mosaic embryo. RESULTS: Of the 405 US assisted reproductive technology clinics contacted, 252 (62.2%) completed a survey, including 157 private (62.3%), 55 academic (21.8%), and 40 hybrid (15.9%) clinics. Most clinics (168, 66.7%) reported conducting preimplantation genetic testing for aneuploidy on less than 50% of all in vitro fertilization cycles. The most common type of preimplantation genetic testing for aneuploidy technology used was next-generation sequencing at 88.9%. Ninety-one clinics (36.1%) receive mosaicism data on their preimplantation genetic testing for aneuploidy report; the most common thresholds for determining embryo aneuploidy and euploidy by clinics' primary genetics laboratories were <20% normal (36.3%) and >80% normal (46.2%), respectively. Thirty-nine (42.9%) of the 91 have transferred and 57 (62.6%) would transfer a mosaic embryo. Nearly 40% of clinics were unsure about their thresholds for mosaic transfer and one fourth of clinics reported they had no threshold. Private (odds ratio, 1.0, 95% confidence interval, 0.5-1.8) and hybrid (odds ratio, 0.9, 95% confidence interval, 0.4-2.1) clinics were just as likely as academic clinics to report having transferred a mosaic embryo. Clinics in the northeastern United States were more likely to have transferred a mosaic embryo than clinics in other regions (odds ratio, 1.5, 95% confidence interval, 0.9-2.7). Most clinics (72.6%) report they do not have a unique consent for transfer of mosaic embryos. CONCLUSION: There is uncertainty and variability in the transfer practices of mosaic embryos and classification of mosaicism among US assisted reproductive technology clinics. These findings provide an opportunity to establish mosaicism thresholds and create standardized guidelines for transferring mosaic embryos. PMID- 30278175 TI - Reply. PMID- 30278176 TI - Hospital variation in utilization and success of trial of labor after a prior cesarean. AB - BACKGROUND: Trial of labor after cesarean delivery is an effective and safe option for women without contraindications. OBJECTIVES: The objective of the study was to examine hospital variation in utilization and success of trial of labor after cesarean delivery and identify associated institutional characteristics and patient outcomes. STUDY DESIGN: Using linked maternal and newborn hospital discharge records and birth certificate data in 2010-2012 from the state of California, we identified 146,185 term singleton mothers with 1 prior cesarean delivery and no congenital anomalies or clear contraindications for trial of labor at 249 hospitals. Risk-standardized utilization and success rates of trial of labor after cesarean delivery were estimated for each hospital after accounting for differences in patient case mix. Risk for severe maternal and newborn morbidities, as well as maternal and newborn length of stay, were compared between hospitals with high utilization and high success rates of trial of labor after cesarean delivery and other hospitals. Bivariate analysis was also conducted to examine the association of various institutional characteristics with hospitals' utilization and success rates of trial of labor after cesarean delivery. RESULTS: In the overall sample, 12.5% of women delivered vaginally. After adjusting for patient clinical risk factors, utilization and success rates of trial of labor after cesarean delivery varied considerably across hospitals, with a median of 35.2% (10th to 90th percentile range: 10.2-67.1%) and 40.5% (10th to 90th percentile range: 8.5-81.1%), respectively. Risk-standardized utilization and success rates of trial of labor after cesarean delivery demonstrated an inverted U-shaped relationship such that low or excessively high use of trial of labor after cesarean delivery was associated with lower success rate. Compared with other births, those delivered at hospitals with above-the median utilization and success rates of trial of labor after cesarean delivery had a higher risk for uterine rupture (adjusted risk ratio, 2.74, P < .001), severe newborn respiratory complications (adjusted risk ratio, 1.46, P < .001), and severe newborn neurological complications/trauma (adjusted risk ratio, 2.48, P < .001), but they had a lower risk for severe newborn infection (adjusted risk ratio, 0.80, P = .003) and overall severe unexpected newborn complications (adjusted risk ratio, 0.86, P < .001) as well as shorter length of stays (adjusted mean ratio, 0.948 for mothers and 0.924 for newborns, P < .001 for both). Teaching status, system affiliation, larger volume, higher neonatal care capacity, anesthesia availability, higher proportion of midwife-attended births, and lower proportion of Medicaid or uninsured patients were positively associated with both utilization and success of trial of labor after cesarean delivery. However, rural location and higher local malpractice insurance premium were negatively associated with the utilization of trial of labor after cesarean delivery, whereas for-profit ownership was associated with lower success rate. CONCLUSION: Utilization and success rates of trial of labor after cesarean delivery varied considerably across hospitals. Strategies to promote vaginal birth should be tailored to hospital needs and characteristics (eg, increase availability of trial of labor after cesarean delivery at hospitals with low utilization rates while being more selective at hospitals with high utilization rates, and targeted support for lower capacity hospitals).

AB - BACKGROUND: Intrauterine devices can offer both contraceptive and noncontraceptive benefits to never sexually active adolescents. There are increasing data on intrauterine device use in adolescents; however, most data on intrauterine devices in adolescents are related to contraceptive use. There is very limited literature on intrauterine device placement in adolescents who have never been sexually active. OBJECTIVE: The objective of the study was to compare intrauterine device insertion success between never sexually active and sexually active cohorts. STUDY DESIGN: We performed a retrospective chart review of patients aged 10-20 years with attempted intrauterine device insertion at a children's hospital between October 2015 and September 2017. RESULTS: A total of 210 patients were included, of whom 82 were never sexually active. Never sexually active adolescents were younger at insertion (15.6 vs 16.7 years, P < .001), more likely to have at least 1 medical problem (75.6% vs 54.7%, P = .046), and to have special needs (23.2% vs 4.7%, P < .001). Never sexually active adolescents were less likely to have intrauterine device insertion performed in the office setting (52.4% vs 94.5%, P < .001). There was no significant difference in success of intrauterine device insertion on the first attempt (90.2% vs 96.1%, P = .086). In a subanalysis of office insertions alone, never sexually active adolescents were more likely to have an unsuccessful intrauterine device insertion (16.3% vs 4.3%, P = .015) and less likely to tolerate the procedure well (81.4% vs 94.2%, P = .026). CONCLUSION: To our knowledge, this is the first study describing intrauterine device insertion in never sexually active patients. Although office success rates were lower, intrauterine device insertion in never sexually active adolescents was very successful overall, and intrauterine devices should be offered to this population.

We propose a triad solution that includes universal screening for cardiovascular disease in pregnancy and postpartum women, patient education, and institution of a multidisciplinary cardiac team. Additionally, we emphasize essential elements to maximize care for the pregnant cardiac patient based on our experience at our institution in Bronx, NY. PMID- 30278181 TI - Association between serotonin-norepinephrine reuptake inhibitors and acute angle closure: what is known? AB - Serotonin-norepinephrine reuptake inhibitors (SNRIs) are widely used antidepressants with a relatively safe profile. One of the complications associated with this group of drugs is acute angle closure (AAC). The mechanisms linking SNRIs and AAC are complex and may be interlinked with the effects of the drug on the inhibition of serotonin and noradrenaline reuptake, as well as pseudo anticholinergic effects, dopaminergic effects, and idiosyncratic reactions with the drug molecule in the eye. Individual characteristics, such as polymorphisms of the gene encoding the 2D6 subunit of cytochrome P450, may affect the metabolism of the SNRI; while, the combination with other drugs may lead to an increased risk of iridocorneal angle closure, and may further exacerbate other mechanisms. Improved knowledge of the mechanisms linking SNRIs and AAC and of the risk factors predisposing to patients to AAC will reduce the number of patients affected by this dangerous complication. PMID- 30278182 TI - A 37 kDa Txp40 protein characterized from Photorhabdus luminescens sub sp. akhurstii conferred injectable and oral toxicity to greater wax moth, Galleria mellonella. AB - Photorhabdus luminescens is a gram-negative bacterium that symbiotically associates with insect-parasitic nematode, Heterorhabditis indica. Herein, we have characterized an insecticidal gene, Txp40 (1008 bp) from the indigenous isolates of P. luminescens, and tested its bioefficacy against Galleria mellonella via injectable and oral bioassay. The recombinant protein characterized from P. luminescens strain H3 exhibited comparatively greater insect toxicity than strain H1 in terms of LD50 and LT50 values. Txp40 holds great potential to replace Bt toxins in global agriculture. PMID- 30278183 TI - Expression of oestrogen receptor beta was negatively correlated with disease activity in patients with Crohn's disease involving the terminal ileum. AB - Crohn's disease (CD) is a chronic inflammatory disease. The recurrence and remission of symptoms in CD patients are associated with changes in hormones, such as in puberty, pregnancy, postpartum and menopause, reflecting that oestrogen and its receptor might play an important role in CD. The study aimed to investigate the expression and clinical significance of oestrogen receptor in patients with CD involving the terminal ileum. Expression of oestrogen receptor alpha (ERalpha) and oestrogen receptor beta (ERbeta) of 37 patients with CD involving the terminal ileum and 21 healthy controls was determined by immunohistochemistry. Disease activity was assessed by Harvey-Bradshow Crohn's disease activity index(Harvey-Bradshow CDAI). Expression of ERalpha was negative for all cases. Moreover, a reduction of ERbeta expression in patients with CD involving the terminal ileum was found, and ERbeta expression had a negative correlation with the disease activity index. These data indicate that ERbeta might be a predictor of CD activity and a new target for further study in CD endocrine therapy. PMID- 30278180 TI - Distribution of mechanical stress in the Escherichia coli cell envelope. AB - The cell envelope in Gram-negative bacteria comprises two distinct membranes with a cell wall between them. There has been a growing interest in understanding the mechanical adaptation of this cell envelope to the osmotic pressure (or turgor pressure), which is generated by the difference in the concentration of solutes between the cytoplasm and the external environment. However, it remains unexplored how the cell wall, the inner membrane (IM), and the outer membrane (OM) effectively protect the cell from this pressure by bearing the resulting surface tension, thus preventing the formation of inner membrane bulges, abnormal cell morphology, spheroplasts and cell lysis. In this study, we have used molecular dynamics (MD) simulations combined with experiments to resolve how and to what extent models of the IM, OM, and cell wall respond to changes in surface tension. We calculated the area compressibility modulus of all three components in simulations from tension-area isotherms. Experiments on monolayers mimicking individual leaflets of the IM and OM were also used to characterize their compressibility. While the membranes become softer as they expand, the cell wall exhibits significant strain stiffening at moderate to high tensions. We integrate these results into a model of the cell envelope in which the OM and cell wall share the tension at low turgor pressure (0.3 atm) but the tension in the cell wall dominates at high values (>1 atm). PMID- 30278184 TI - Human neuroblastoma SH-SY5Y cells treated with okadaic acid express phosphorylated high molecular weight tau-immunoreactive protein species. AB - BACKGROUND: Early stages of Alzheimer's disease (AD) are characterized by high phosphorylation of microtubule-associated protein tau, which may result from the downregulation of protein phosphatases. NEW METHOD: In order to model phosphatase downregulation and analyze its effect on tau aggregation in vitro, we treated neuroblastoma SH-SY5Y cells with okadaic acid (OA), a protein phosphatase inhibitor, and examined high molecular weight phospho-tau species. RESULTS AND COMPARISON WITH EXISTING METHODS: OA treatment led to the appearance of heat stable protein species with apparent molecular weight around 100 kDa, which were immunoreactive to anti-tau antibodies against phosphorylated Ser202 and Ser396. As these high molecular weight tau-immunoreactive proteins (HMW-TIPs) corresponded to the predicted size of two tau monomers, we considered the possibility that they represent phosphorylation-induced tau oligomers. We attempted to dissociate HMW-TIPs by urea and guanidine, as well as by alkaline phosphatase treatment, but HMW-TIPs were stable under all conditions tested. These characteristics resemble properties of certain sodium dodecyl sulfate (SDS) resistant tau oligomers from AD brains. The absence of HMW-TIPs detection by anti total tau antibodies Tau46, CP27 and Tau13 may be a consequence of epitope masking and protein truncation. Alternatively, HMW-TIPs may represent previously unreported phosphoproteins cross-reacting with tau. CONCLUSIONS: Taken together, our data provide a novel characterization of an OA-based cell culture model in which OA induces the appearance of HMW-TIPs. These findings have implications for further studies of tau under the conditions of protein phosphatase downregulation, aiming to explain mechanisms involved in early events leading to AD. PMID- 30278185 TI - Minimalistic in vitro systems for investigating tau pathology. AB - Neurofibrillary tangles, formed of hyperphosphorylated, misfolded tau accumulations, are a pathological hallmark of neurodegenerative diseases such as Alzheimer's disease (AD) and frontotemporal dementia. The neuroanatomical localisation of tau pathology in AD brains of different disease stages suggests that tau tangle pathology is spreading throughout the brain along connected neuronal circuits. Pathogenic tau can act as a prion-like seed, inducing the misfolding of native tau and leading to disease propagation throughout the brain. However, it is not yet fully understood how tau spreads between individual neurons or brain regions. Here, we review the models for investigating tau propagation in vitro, and summarise the findings from key studies into the mechanisms of tau pathology propagation in disease. PMID- 30278186 TI - Transgenerational plasticity and antiviral immunity in the Pacific oyster (Crassostrea gigas) against Ostreid herpesvirus 1 (OsHV-1). AB - The oyster's immune system is capable of adapting upon exposure to a pathogen associated molecular pattern (PAMP) to have an enhanced secondary response against the same type of pathogen. This has been demonstrated using poly(I:C) to elicit an antiviral response in the Pacific oyster (Crassostrea gigas) against Ostreid herpesvirus (OsHV-1). Improved survival following exposure to poly(I:C) has been found in later life stages (within-generational immune priming) and in the next generation (transgenerational immune priming). The mechanism that the oyster uses to transfer immunity to the next generation is unknown. Here we show that oyster larvae have higher survival to OsHV-1 when their mothers, but not their fathers, are exposed to poly(I:C) prior to spawning. RNA-seq provided no evidence to suggest that parental exposure to poly(I:C) reconfigures antiviral gene expression in unchallenged larvae. We conclude that the improved survival of larvae might occur via maternal provisioning of antiviral compounds in the eggs. PMID- 30278187 TI - Mechanistic Analysis of Cocrystal Dissolution, Surface pH, and Dissolution Advantage as a Guide for Rational Selection. AB - The dissolution behavior of a dibasic drug ketoconazole under the influence of pH has been evaluated and compared to its three 1:1 cocrystals with diacidic coformers, fumaric acid, succinic acid (SUC), and adipic acid. Mass transport models were developed by applying Fick's law of diffusion to dissolution with simultaneous chemical reactions in the hydrodynamic boundary layer adjacent to the dissolving surface to predict the interfacial pH and flux of the parent drug and cocrystals. All 3 cocrystals have the ability to modulate the interfacial pH to different extents compared to the parent drug due to the acidity of the coformers. Dissolution pH dependence of ketoconazole is significantly reduced by the cocrystallization with acidic coformers. Due to the different dissolution pH dependence, there exists a transition pH where the flux of the cocrystal is the same as the parent drug. Below this transition pH, the drug flux is higher, but above it, the cocrystal flux is higher. The development of these mass transport models provide a mechanistic understanding of the dissolution behavior and help identify cocrystalline solids with optimal dissolution characteristics. PMID- 30278188 TI - Nicotinamide Mononucleotide Adenylyltransferase 2 maintains neuronal structural integrity through the maintenance of golgi structure. AB - Golgi fragmentation and loss of Nicotinamide Mononucleotide Adenylyltransferase 2 (NMNAT2) are the early key features of many neurodegenerative disorders. We investigated the link between NMNAT2 loss, Golgi fragmentation and axon degeneration. Golgi fragmentation in the cultured dorsal root ganglion (DRG) neurons resulted in caspase dependent axon degeneration and neuronal cell death. NMNAT2 depletion in the DRG neurons caused Golgi fragmentation and caspase dependent axon degeneration. NMNAT2 depletion did not cause ATP loss in the axons. These results indicate that NMNAT2 is required for maintenance of Golgi structure. Loss of Golgi structure or Nmnat2 depletion causes caspase dependent neurodegeneration. cytNmnat1 overexpression inhibited the axon degeneration induced by Golgi fragmentation or NMNAT2 depletion. These results also suggest that these degeneration signals converge on a common cytNmnat1 mediated axon protective program and are distinct from the SARM1 mediated caspase independent axon degeneration. PMID- 30278189 TI - Enhancement of fear learning in PPARalpha knockout mice. AB - Peroxisome proliferator-activated receptor alpha (PPARalpha) is a member of the nuclear receptor superfamily and regulates fatty acid oxidation. Although PPARalpha is expressed not only in the peripheral tissues but also in the brain, its role in higher brain function is unclear. In this study, we investigated the role of PPARalpha in the control of behavior, including memory/learning and mood change, using PPARalpha knockout (KO) mice. A significant difference between wild type (WT) and KO mice was seen in the passive avoidance test, demonstrating that KO mice showed enhanced fear leaning. In the amygdala of KO mice, the levels of dopamine and its metabolites were increased, and the mRNA expression of dopamine degrading enzyme was decreased. When dopamine D1 receptor antagonist was administered, the enhanced fear learning observed in KO mice was attenuated. These results suggest that PPARalpha is involved in the regulation of emotional memory via the dopamine pathway in the amygdala. PMID- 30278190 TI - Twitter Mentions and Academic Citations in the Urologic Literature. AB - OBJECTIVE: To quantify the relationship between the number of Twitter mentions and the number of academic citations a urologic publication receives. MATERIALS AND METHODS: Two hundred and thirteen papers from 7 prominent urologic journals were examined 37 months after publication. Articles were evaluated with 2 citation based "bibliometrics" (Scopus, Google Scholar) and Twitter mentions were tracked using the Altmetric Bookmarklet. The number of article citations and Twitter mentions were compared using one-way Analysis of variance (ANOVA) and bivariate fit analysis. RESULTS: Seventy-three percent of articles had at least 1 Twitter mention. Forty-two percent of Twitter mentions occurred within the first week of the online publication date. Articles mentioned on Twitter had 2.0-fold more Scopus citations (P <.01), and 2.3-fold more Google Scholar citations (P <. 01) compared to articles with no Twitter mentions. Female urologic articles had the greatest number of Twitter mentions (5.7 mentions/article) while pediatric urology had the fewest mean number of Twitter mentions (0.8 mentions/article). A total of 8.9% of papers were tweeted by their authors. Author tweeted articles were associated with a 12.3 (2.0-fold) and 15.5 (1.8-fold) mean citation increase for Scopus and Google Scholar (P <. 01 and P = . 01) compared to articles not shared by their authors on Twitter. CONCLUSION: The majority of urologic publications are being shared on Twitter. The number of citations a urologic publication receives up to 3 years after release is positively associated with the number of mentions it has on Twitter. Twitter activity may be an early indicator of ultimate academic impact of an academic urologic paper. PMID- 30278191 TI - Dengue virus enters and exits epithelial cells through both apical and basolateral surfaces and perturbs the apical junctional complex. AB - Dengue is the most relevant mosquito-borne viral disease in the world. It has been estimated that 390 million infections of dengue occur each year. Dengue virus (DENV) infection can be asymptomatic or can produce a self-limited febrile illness called dengue fever (DF) or a severe form of the infection called severe dengue. In some viruses, the entry and egress from cells, occur in a specific domain of polarized endothelial and epithelial cells. In this study, we investigated whether the entry and release of DENV was polarized in epithelial cells, and evaluated the effect of DENV infection on cellular junctions of epithelial cells. We used MDCK epithelial cells, which serve as an excellent model to study a functional barrier due to the presence of an apical junctional complex (AJC), and showed that entry and release of DENV from the cells, is bipolar. Additionally, we performed paracellular flux, diffusion of membrane lipid, immunofluorescence and immunoblotting assays to evaluate the integrity of the AJC during DENV infection. We observed that at later stages of infection, DENV altered the barrier function causing a decrease in the transepithelial electrical resistance and the degradation and delocalization of TJ and AJ proteins. The present study contributes to understand how DENV traverse epithelia in order to cause a productive infection, and provides insights into the mechanism of DENV pathogenesis. PMID- 30278192 TI - G protein-coupled receptor heteromers are key players in substance use disorder. AB - G protein-coupled receptors (GPCR) represent the largest family of membrane proteins in the human genome. Physical association between two different GPCRs is linked to functional interactions which generates a novel entity, called heteromer, with specific ligand binding and signaling properties. Heteromerization is increasingly recognized to take place in the mesocorticolimbic pathway and to contribute to various aspects related to substance use disorder. This review focuses on heteromers identified in brain areas relevant to drug addiction. We report changes at the molecular and cellular levels that establish specific functional impact and highlight behavioral outcome in preclinical models. Finally, we briefly discuss selective targeting of native heteromers as an innovative therapeutic option. PMID- 30278193 TI - Systematic review of co-occurring OCD and TD: Evidence for a tic-related OCD subtype? AB - OBJECTIVE: The aim of this review is to summarize the current knowledge of associated features of co-occurring obsessive-compulsive disorder (OCD) and tic disorders (TD) and to critically evaluate hypotheses regarding the nature of their comorbidity. METHOD: We conducted a systematic review following PRISMA guidelines. To this aim, the PubMed, PsychInfo and ISI Web of Knowledge databases were searched up to August 30, 2018. For gender and age-of-onset we additionally conducted meta-analyses. RESULTS: One hundred eighty-nine studies met inclusion criteria. We substantiate some acknowledged features and report evidence for differential biological mechanisms and treatment response. In general, studies were of limited methodological quality. CONCLUSIONS: Several specific features are reliable associated with co-occurring OCD + TD. The field lacks methodological sound studies. The review found evidence against and in favor for different hypotheses regarding the nature of comorbidity of OCD and TD. This could indicate the existence of a stepwise model of co-morbidity, or could be an artefact of the low methodological quality of studies. PMID- 30278194 TI - Social touch during development: Long-term effects on brain and behavior. AB - In this paper, our goal is to explore what is known about the role of social touch during development. We first address the neural substrates of social touch and the role of tactile experience in neural development. We discuss natural variation in early exposure to social touch, followed by a discussion on experimental manipulations of social touch during development and "natural experiments", such as early institutionalization. We then consider the role of other developmental and experiential variables that predict social touch in adults. Throughout, we propose and consider new theoretical models of the role of social touch during development on later behavior and neurobiology. PMID- 30278196 TI - Longitudinal Study of Dark Adaptation as a Functional Outcome Measure for Age Related Macular Degeneration. AB - PURPOSE: To investigate the natural history of dark adaptation (DA) function as measured by the change in rod intercept time (RIT) over 4 years and to correlate RIT change with age-related macular degeneration (AMD) severity. DESIGN: Longitudinal, single-center, observational study. PARTICIPANTS: A total of 77 participants aged >=50 years with a range of AMD severities. METHODS: Participants each contributing a single study eye to the analysis were assigned into person-based AMD severity groups based on fundus characteristics (drusen, pigmentary changes, late AMD, and subretinal drusenoid deposits [SDDs]). The DA function was assessed in study eyes at baseline and 3, 6, 12, 18, 24, 36, and 48 months. Mean change in DA function over time was calculated using the slope of linear regression fits of longitudinal RIT data. Patient-reported responses on a Low Luminance Questionnaire (LLQ) were obtained at baseline and yearly. Nonparametric statistical testing was performed on all comparisons. MAIN OUTCOME MEASURE: The RIT, defined as the time taken after a photobleach for visual sensitivity to recover detection of a 5*10-3 cd/m2 stimulus (a decrease of 3 log units), was monitored in study eyes over 4 years, and the mean rate of change was computed. RESULTS: Longitudinal analysis of 65 study eyes followed on the standard testing protocol (mean age, 71+/-9.3 years; 49% were female) revealed that higher rates of RIT prolongation were correlated with AMD severity group assignment at baseline (P = 0.026) and with severity group assignments at year 4 (P = 0.0011). Study eyes that developed SDD during follow-up demonstrated higher rates of RIT prolongation relative to those that did not (P < 0.0001). Overall, higher rates of RIT prolongation were significantly correlated with greater 4 year decreases in LLQ scores (total mean score, P = 0.0032). CONCLUSIONS: Longitudinal decline in DA function, which correlated with patient-reported functional deficits, was accelerated in eyes with greater AMD severity and especially in eyes with SDD both at baseline and at 4 years. The RIT prolongation as a measure of changing DA function may be a functional outcome measure in AMD clinical studies. PMID- 30278197 TI - Selective Laser Trabeculoplasty versus Argon Laser Trabeculoplasty in Glaucoma Patients Treated Previously with 360 degrees Selective Laser Trabeculoplasty: A Randomized, Single-Blind, Equivalence Clinical Trial. AB - PURPOSE: The effectiveness of selective laser trabeculoplasty (SLT) was compared with argon laser trabeculoplasty (ALT) in a randomized clinical trial for patients with medically uncontrolled open-angle glaucoma who have previously received 360 degrees SLT. DESIGN: An active equivalence parallel armed randomized control trial. PARTICIPANTS: Patients with open-angle glaucoma including pigmentary dispersion syndrome and pseudoexfoliation syndrome were enrolled into the study from 7 different sites across Canada. METHODS: One setting of 180 degrees of either SLT or ALT was assigned randomly and applied to each participant. MAIN OUTCOME MEASURES: The change in intraocular pressure (IOP) from baseline to 12 months was compared between the 2 groups. RESULTS: A total of 132 patients were recruited, 2 of which dropped out early in the study, leaving 130 patients who completed the study as per protocol. For those, the study's primary outcome was calculated. The IOP change at 1 year in comparison to baseline for SLT vs. ALT was found to be different by 0.33 mmHg between the 2 groups (3.16 for SLT and 2.83 for ALT) and was not statistically significant (P = 0.71) Further analysis, though, showed that SLT had a significantly lower IOP reduction at early time points: 1 week and 1 month, but this effect was lost by 3 months. Corresponding to this finding was the strong trend for ALT to fail more quickly than SLT. Although repeatable, the first repeat SLT reduced IOP to only about half compared with initial SLT treatment. CONCLUSIONS: The comparison at 12 months following the laser therapy showed that both modalities lowered the IOP with approximately 3 mmHg, yet essentially all of the time-to-failure analyses favored SLT over ALT. The repeat SLT effect was found to be half of the initial treatment. PMID- 30278195 TI - Meta-analyses of the neural mechanisms and predictors of response to psychotherapy in depression and anxiety. AB - Understanding the neural mechanisms underlying psychological therapy could aid understanding of recovery processes and help target treatments. The dual-process model hypothesises that psychological therapy is associated with increased emotional-regulation in prefrontal brain regions and decreased implicit emotional reactivity in limbic regions; however, research has yielded inconsistent findings. Meta-analyses of brain activity changes accompanying psychological therapy (22 studies, n = 352) and neural predictors of symptomatic improvement (11 studies, n = 293) in depression and anxiety were conducted using seed-based d mapping. Both resting-state and task-based studies were included, and analysed together and separately. The most robust findings were significant decreases in anterior cingulate/paracingulate gyrus, inferior frontal gyrus and insula activation after therapy. Cuneus activation was predictive of subsequent symptom change. The results are in agreement with neural models of improved emotional reactivity following therapy as evidenced by decreased activity within the anterior cingulate and insula. We propose compensatory as well as corrective neural mechanisms of action underlie therapeutic efficacy, and suggest the dual process model may be too simplistic to account fully for treatment mechanisms. More research on predictors of psychotherapeutic response is required to provide reliable predictors of response. PMID- 30278198 TI - Construction and application of (Q)SAR models to predict chemical-induced in vitro chromosome aberrations. AB - In drug development, genetic toxicology studies are conducted using in vitro and in vivo assays to identify potential mutagenic and clastogenic effects, as outlined in the International Council for Harmonisation (ICH) S2 regulatory guideline. (Quantitative) structure-activity relationship ((Q)SAR) models that predict assay outcomes can be used as an early screen to prioritize pharmaceutical candidates, or later during product development to evaluate safety when experimental data are unavailable or inconclusive. In the current study, two commercial QSAR platforms were used to build models for in vitro chromosomal aberrations in Chinese hamster lung (CHL) and Chinese hamster ovary (CHO) cells. Cross-validated CHL model predictive performance showed sensitivity of 80 and 82%, and negative predictivity of 75 and 76% based on 875 training set compounds. For CHO, sensitivity of 61 and 67% and negative predictivity of 68 and 74% was achieved based on 817 training set compounds. The predictive performance of structural alerts in a commercial expert rule-based SAR software was also investigated and showed positive predictivity of 48-100% for selected alerts. Case studies examining incorrectly-predicted compounds, non-DNA-reactive clastogens, and recently-approved pharmaceuticals are presented, exploring how an investigational approach using similarity searching and expert knowledge can improve upon individual (Q)SAR predictions of the clastogenicity of drugs. PMID- 30278199 TI - Effect of melatonin on attenuating the isoflurane-induced oxidative damage is related to PKCalpha/Nrf2 signaling pathway in developing rats. AB - Isoflurane, an inhalational anesthesia, has frequently been used in pediatric anesthesia. However, research indicates that isoflurane can induce oxidative stress and affect neural and cognitive development. Melatonin, an endogenous hormone that exhibits antioxidant functions, can play a neuroprotective role by activating the PKCalpha/Nrf2 signaling pathway in response to oxidative stress. This study aims to determine whether the effect of melatonin on isoflurane induced oxidative stress is related to activation of the PKCalpha/Nrf2 signaling pathway. Rat pups at postnatal day 7 were treated with control or 1.5% isoflurane for 4 h after pretreatment for 15 min with either melatonin (10 mg/kg i.p.) or 1% ethanol. The hematoxylin and eosin staining and transmission electron microscopic examination were used for observation of histopathology. The oxidative stress related indicators were detected by using assay kits. The western blotting, immunohistochemistry and immunofluorescence were used to detect the activation of PKCalpha/Nrf2 signaling pathway. Results showed that isoflurane induced nerve damage in the hippocampus, and melatonin could reduce this injury. Oxidative stress-related indicators suggested that isoflurane can significantly increase reactive oxygen species and malondialdehyde levels, and decrease superoxide dismutase and glutathione activity compared with the control group, whereas melatonin ameliorated these indices. Expression of proteins associated with the PKCalpha/Nrf2 signaling pathway indicated that the neuroprotective effect of melatonin is related to activation of the PKCalpha/Nrf2 signaling pathway. These results suggest that the attenuating effect of melatonin on isoflurane-induced oxidative stress is related to activation of the PKCalpha/Nrf2 signaling pathway. These findings promote further research into underlying mechanisms and effective treatments to attenuate anesthesia neurotoxicity. PMID- 30278200 TI - Antidepressant-like effects of insulin and IGF-1 are mediated by IGF-1 receptors in the brain. AB - Depression is associated with uncontrolled diabetes, which indicates a lack of insulin effect, yet the role of the insulin receptor in mediating depression is not clearly established because insulin receptors are not required for glucose entry into the brain. However, insulin receptors are important for brain function since insulin receptor knockout mice have depressive-like activity. Depression and cognitive problems are also associated with low insulin-like growth factor-1 (IGF-1) in the elderly. Rodent studies showed chronic IGF-1 administration had antidepressant-like (AD) activity. We asked if insulin in the brain might act through the IGF-1 receptor, as it does in some tissues. We used acute insulin or IGF-1 infusions into the 3rd ventricle (icv) in rats and tested animals in a forced swim test. We found that antidepressive-like behavior is mediated by insulin and IGF-1. Further, administration of the IGF-1 receptor antagonist JB-1 blocked the antidepressive-like activity of the insulin and IGF-1, indicating a strong relationship between insulin, IGF-1 and depression. Insulin acts at least partially through the IGF-1 receptor and is responsive to receptor antagonism. The model offers promise for future studies of the mechanism of depression, and therapy to increase insulin sensitivity and IGF-1 action including exercise and nutrition. PMID- 30278201 TI - Cell differentiation processes as spatial networks: Identifying four-dimensional structure in embryogenesis. AB - One overarching principle of eukaroytic development is the generative spatial emergence and self-organization of cell populations. As cells divide and differentiate, they and their descendents form a spatiotemporal explicit and increasingly compartmentalized complex system. Yet despite this comparmentalization, there is selective functional overlap between these structural components. While contemporary tools such as lineage trees and molecular signaling networks prvide a window into this complexity, they do not characterize embryogenesis as a global process. Using a four-dimensional spatial representation, major features of the developmental process are revealed. To establish the role of developmental mechanisms that turn a spherical embryo into a highly asymmetrical adult phenotype, we can map the outcomes of the cell division process to a complex network model. This representational model provides information about the top-down mechanisms relevant to the differentiation process. In a complementary manner, looking for phenomena such as superdiffusive positioning and sublineage-based anatomical clustering incorporates dynamic information to our parallel view of embryogenesis. Characterizing the spatial organization and geometry of embryos in this way allows for novel indicators of developmental patterns both within and between organisms.

PMID- 30278203 TI - Duration of therapeutic hypothermia or targeted temperature management in pediatric cardiac arrest: Seeing through the ice. PMID- 30278204 TI - Enhancement of capnogram waveform in the presence of chest compression artefact during cardiopulmonary resuscitation. AB - BACKGROUND: Current resuscitation guidelines emphasize the use of waveform capnography to help guide rescuers during cardiopulmonary resuscitation (CPR). However, chest compressions often cause oscillations in the capnogram, impeding its reliable interpretation, either visual or automated. The aim of the study was to design an algorithm to enhance waveform capnography by suppressing the chest compression artefact. METHODS: Monitor-defibrillator recordings from 202 patients in out-of-hospital cardiac arrest were analysed. Capnograms were classified according to the morphology of the artefact. Ventilations were annotated using the transthoracic impedance signal acquired through defibrillation pads. The suppression algorithm is designed to operate in real-time, locating distorted intervals and restoring the envelope of the capnogram. We evaluated the improvement in automated ventilation detection, estimation of ventilation rate, and detection of excessive ventilation rates (over-ventilation) using the capnograms before and after artefact suppression. RESULTS: A total of 44 267 ventilations were annotated. After artefact suppression, sensitivity (Se) and positive predictive value (PPV) of the ventilation detector increased from 91.9/89.5% to 98.0/97.3% in the distorted episodes (83/202). Improvement was most noticeable for high-amplitude artefact, for which Se/PPV raised from 77.6/73.5% to 97.1/96.1%. Estimation of ventilation rate and detection of over-ventilation also upgraded. The suppression algorithm had minimal impact in non-distorted data. CONCLUSION: Ventilation detection based on waveform capnography improved after chest compression artefact suppression. Moreover, the algorithm enhances the capnogram tracing, potentially improving its clinical interpretation during CPR. Prospective research in clinical settings is needed to understand the feasibility and utility of the method. PMID- 30278205 TI - Transcriptomics and metabonomics of the anti-aging properties of total flavones of Epimedium in relation to lipid metabolism. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Total flavones of Epimedium (TFE) is the main active ingredient in Herba Epimedii, which is a well-known Chinese herbal medicine that is widely used to treat certain age-related diseases in oriental countries. AIM OF THE STUDY: The aim of this work was to investigate the anti aging properties of TFE related to lipid metabolism. MATERIALS AND METHODS: Both transcriptomics and metabonomics were applied in this work to investigate the anti-aging properties of TFE. Microarray and LC-MS analysis were conducted on liver samples of three groups of rats, including young (4 months), old (24 months), and old rats administrated TFE. RESULTS: Transcriptomics analysis highlighted 287 transcripts related to the anti-aging effect of TFE, in which the expression ratio of 18 genes regulating lipid metabolism, including HMGCS1 and NR1H3, returned to normal levels after TFE treatment. In addition, 24 aging related metabolites were discovered in a metabonomics study, and 15 of these were structurally identified, including palmitic amide, linoleamide, and oleamide. Bioinformatics and integral data analysis on the results of the transcriptomics and metabonomics suggest the involvement of 12 key metabolic pathways, half of which are highly related to lipid metabolism. CONCLUSIONS: This study demonstrates that the role played by TFE in the lipid metabolism of aging rats is multifaceted and multi-layered.

AB - Adoption of biotech crops engineered to express insecticidal toxins from Bacillus thuringiensis (Bt) has revolutionized insect pest control in agriculture. For continuing effective application and development of the environmentally friendly Bt biotechnology, it is fundamental to understand pathways of toxicity of Bt toxins in insects. In this study, mutations were introduced in the midgut cadherin gene in the cabbage looper, Trichoplusia ni, by CRISPR/Cas9 mutagenesis. T. ni strains with mutations in the genes of two major receptors for Bt toxins, the midgut cadherin and ABCC2, and three Cry1A toxins with shared and differential midgut binding sites were used as an experimental system to dissect the roles of the cadherin and ABCC2 in the pathways of toxicity of Bt toxins. Results from assays of responses of the T. ni strains to different Bt toxins revealed that the cadherin and ABCC2 play independent roles in the mode of action of Cry1A toxins and that Bt toxins exert insecticidal activity through multiple redundant pathways of toxicity in insects. Besides the cadherin and ABCC2 pathways, there exists an additional major pathway of toxicity to be identified for Cry1Aa. The results also confirmed that the toxicity of Cry2Ab involves neither the cadherin nor the ABCC2 protein. The multiple pathway model for Bt toxins clarified from this study provided new insights into the molecular modes of action of Bt toxins and mechanisms of insect resistance to Bt toxins. PMID- 30278207 TI - Proteomics reveals localization of cuticular proteins in Anopheles gambiae. AB - Anopheles gambiae devotes over 2% of its protein coding genes to its 298 structural cuticular proteins (CPs). This paper provides new LC-MS/MS data on two adult structures, proboscises and palps, as well as three larval samples - 4th instar larvae, just their terminal segment, and a preparation enriched in their tracheae. These data were combined with our previously published results of proteins from five other adult structures, whole adults, and two preparations chosen for their relatively clean cuticle, the larval head capsules left behind after ecdysis and the pupal cuticles left behind after adult eclosion. Peptides from 28 CPs were recovered in all adult structures; 24 CPs were identified for the first time, 6 of these were members of the TWDL family. Most newly identified proteins came from the larval sources. Based solely on peptide recovery, from our data and from other investigators, most available on VectorBase, there were only 4 CPs that were restricted to a single adult structure. More were restricted to a single metamorphic stage, 14 in larvae, 0 in pupae and 32 in adults. Expression data from our earlier RT-qPCR studies reduces these numbers. Charting restriction of CPs to stage or structure is a step forward in establishing their specific roles. PMID- 30278208 TI - Bacterial respiratory tract inflammation in neonatal rat model is attenuated by benzofuran through inhibition of GATA3. AB - The current study was aimed to investigate the effect of benzofuran on asthma neonatal rat model. Twenty-five neonatal rats were assigned into five groups; Normal control, untreated, 1 mg/kg, 8 mg/kg and 10 mg/kg treatment groups. Methacholine was administered orally to the rats of untreated and treatment groups. Animals in the normal control group were given PBS as a vehicle. FlexiVent system employing a computer-controlled mouse ventilator along with respiratory mechanics was used for the analysis of airway resistance in the rats. Cytokine level and IFN-gamma in the rat serum samples was performed by ELISA in accordance with the instructions of manufacturer. Methacholine administration into the rats caused a marked increase in lung airway resistance. However, treatment with 8 and 10 mg/kg doses of benzofuran led to marked decrease in the airway resistance. Benzofuran treatment prevented accumulation of macrophages and inflammatory cells in the lung airways. Inhibition of inflammation in methacholine administered rats by benzofuran was also confirmed by hematoxylin & eosin-staining. Examination of the rat serum showed significantly higher level of Th2 cytokines (IL-4, -5 and -13) in the untreated rats. However, treatment of methacholine administered rats with benzofuran significantly inhibited Th2 cytokine expression. The level of IFN-gamma was increased by benzofuran treatment in methacholine administered rats. In methacholine administered rats the level of IgE was markedly higher however treatment of asthma rats with benzofuran inhibited up-regulation of IgE significantly. The expression of T-bet is decreased and that of GATA-3 is increased by methacholine administration in the rat lungs. Benzofuran treatment of methacholine administered rats prevented reduction in T-bet and up-regulation of GATA-3 expression in the rat lungs. The effect of benzofuran was significant at the doses of 8 and 10 mg/kg and non significant at 1 mg/kg. These finding suggest that benzofuran inhibits expression of dominant T-helper 2 cytokines through targeting GATA-binding protein 3 transcription factor. Thus benzofuran can be of therapeutic importance for the treatment of asthma. PMID- 30278209 TI - Structural and functional characterization for interaction of silver nanoparticles with ergostrol in Trichoderma harzianum. AB - Silver ions, because of its recognised antimicrobial activity are reported in several regions for the very long time while ergosterol, apart from its role as a secondary metabolite, structural component of the fungal cell membranes, also turns out to be activating defence response in plants. Silver ions biosynthesized by terpene ergosterol producing Trichoderma harzianum could be used against other plant pathogenic fungi. In this work, possible interaction of the silver ions with ergosterol enzyme has been investigated using a computational approach. Protein model construction via prior knowledge of sequences and molecular ligand docking experiments as well as structural and sequence comparisons were executed to identify potential active-site in ergosterol enzyme. Moldock score of -48.5747 with the reranking score of -40.0228 has been reported by Molegro Virtual Docker(MVD) at ergosterol enzyme's active site positions for silver ion. Apart from the core of the active site, four other positions have been occupied by silver ion. The interacting site surrounded by Cys339, Arg343, Lue365, Leu336 and Trp371 formed hydrophobic bonds with silver. The anti-microbial activity against phytopathogens is believed to increase synergistically when combined with ergosterol enzyme. Thus the computational analysis of silver ion in conjugation with ergosterol enzyme provided additional strategies to improve the ability of the Trichoderma strains in biocontrol of pathogenic fungi. In the present study, silver ion based formulations which are produced by strong bio-control fungi as shown were estimated in response to different plant pathogen in further studies. PMID- 30278210 TI - Long-term arsenite exposure induces testicular toxicity by redox imbalance, G2/M cell arrest and apoptosis in mice. AB - Inorganic arsenic (iAs), a ubiquitous element and a natural drinking water contaminant, has been found to impair male reproductive function. However, the effect of long-term exposure to arsenic on testis damage and its underlying mechanisms still require further evaluation. In the study, male C57BL/6 mice (4 weeks) were treated with sodium arsenite at the doses of 5 or 50 ppm arsenic via drinking water for 180 days. Sperm count, histology in testes, oxidative stress biomarkers, cell cycle progress and apoptosis were assessed. Our results showed that arsenite seriously destroyed the structure of the testes and reduced the sperm count. Arsenite significantly decreased the activity of total superoxide dismutase (T-SOD) and glutathione (GSH) content but increased the levels of reactive oxygen species (ROS) and malondialdehyde (MDA) in testes. Furthermore, arsenite could induce G2/M phase arrest in testes, concurrent with a significant decrease in mRNA and protein levels of cdc2 and cyclin B1, the upregulation of p cdc2, and an increase in mRNA levels of p53 and p21. Arsenite induced testicular apoptosis with a significant increase in Bax mRNA and protein levels, especially the caspase-3 activation. Testicular toxicity of the high dose group was stronger than that of the low dose group. In conclusion, testicular toxicity due to long term exposure to arsenite may relate to oxidative damage, G2/M arrest and promoted apoptosis in the testes of mice, which contributed to the increased risk of spermatogenesis disorders and male infertility. PMID- 30278211 TI - Great Himalayan leaf-nosed bats modify vocalizations to communicate threat escalation during agonistic interactions. AB - Bats vocalize extensively within various social contexts. Nevertheless, studies of agonistic interactions, associating vocalizations signalling the emotional state of a caller with individual signatures during aggressive vocalizations remain scarce. Here, we examined whether male Great Himalayan leaf-nosed bats (Hipposideros armiger) modify their aggressive vocalizations during agonistic interactions depending on the level of aggression, and whether these vocalizations encode individual signatures. We applied a cost-benefit analysis to audio-video recordings of 50 dyadic agonistic interactions to categorize displays into two levels of aggression intensity (low aggression: bared teeth, slightly pulled up body and/or wings; high aggression: rapidly flapping wings, punching, biting). Male H. armiger used graded visual agonistic displays accompanied by bent upward frequency modulation (bUFM) vocalizations to defend their roosting territories. At high aggression intensities, males decreased the minimum frequency of aggressive calls and increased the frequency bandwidth. Males also transferred energy from the second harmonic to the first harmonic as the threat escalated. These systematic modifications of acoustic parameters as aggressive intensity fluctuated corresponded to prosodic modifications in human speech, indicating that emotion-related acoustic cues are a common feature of acoustic communication in mammals. In addition, we found that the aggressive calls of eight adult males encoded discriminable signatures, and that males could discriminate among individuals based on these aggressive calls. Such discrimination is probably useful for individual identification among rival neighbours. PMID- 30278212 TI - The reporting of safety among drug systematic reviews was poor before the implementation of the PRISMA harms checklist. AB - OBJECTIVES: To examine, through a cross-sectional survey, how well safety information was reported among drug systematic reviews predating PRISMA harms checklist and explore factors associated with better reporting. STUDY DESIGN AND SETTING: We searched PubMed to identify all systematic reviews published in the Cochrane Database of Systematic Review or the core clinical journals in 2015, one year before the PRISMA harms checklist was published. We randomly selected, in a 1:1 ratio, Cochrane and non-Cochrane systematic reviews assessing drug effects (including both efficacy and safety). We used the PRISMA harms checklist published in 2016 to assess the quality of reporting of drug safety information. Multivariable linear regression analyses were used to explore the association of six prespecified variables with more complete reporting of PRISMA harms items. RESULTS: We included 120 systematic reviews, including 60 Cochrane and 60 non Cochrane reviews. Scores on the PRISMA harms checklist (23 items) were low (median 4, [first, third quartile: 2, 6]), with no difference between Cochrane and non-Cochrane reviews (4.5 [2, 7] vs. 4 [2.5, 5]; P = 0.29). Among all eligible reviews, only one item (i.e., state conclusions in coherence with the review findings) was reported adequately (proportion of adherence 81.6%); proportion of reporting for other items ranged from 1.7% to 68.3%. The four essential reporting items from PRISMA harms checklist were also poorly complied (proportion of adherence ranged from 1.7% to 9.2%). Multivariable linear regression analyses found no significant associations between any study characteristic and reporting on the PRISMA harms, likely because of limited variability in scores across studies. CONCLUSIONS: The reporting of safety information was poor both for Cochrane and non-Cochrane drug systematic reviews predating PRISMA harms checklist. The findings suggested a strong need to use the PRISMA harms checklist for reporting safety among drug systematic reviews. PMID- 30278213 TI - Tailored meta-analysis: an investigation of the correlation between the test positive rate and prevalence. AB - BACKGROUND: Meta-analysis may produce estimates that are unrepresentative of a test's performance in practice. Tailored meta-analysis (TMA) circumvents this by deriving an applicable region for the practice and selecting the studies compatible with the region. It requires the test positive rate, r and prevalence, p being estimated for the setting but previous studies have assumed their independence. The aim is to investigate the effects a correlation between r and p has on estimating the applicable region and how this affects TMA. METHOD: Six methods for estimating 99% confidence intervals (CI) for r and p were investigated: Wilson's +/- Bonferroni correction, Clopper-Pearson's +/- Bonferroni correction and Hotelling's T2 statistic +/- continuity correction. These were analysed in terms of the coverage probability using simulation trials over different correlations, sample sizes, and values for r and p. The methods were then applied to two published meta-analyses with associated practice data and the effects on the applicable region, studies selected and summary estimates evaluated. RESULTS: Hotelling's T2 statistic with a continuity correction had the highest median coverage (0.9971). This and the Clopper-Pearson method with a Bonferroni correction both had coverage consistently above 0.99. The coverage of Hotelling's CI's varied the least across different correlations. For both meta analyses, the number of studies selected was largest when Hotelling's T2 statistic was used to derive the applicable region. In one instance this increased the sensitivity by over 4% compared with TMA estimates using other methods. CONCLUSION: TMA returns estimates which are tailored to practice providing the applicable region is accurately defined. This is most likely when the CI for r and p are estimated using Hotelling's T2 statistic with a continuity correction. Potentially, the applicable region may be obtained using routine electronic health data. PMID- 30278214 TI - Dual-calibrated fMRI measurement of absolute cerebral metabolic rate of oxygen consumption and effective oxygen diffusivity. AB - Dual-calibrated fMRI is a multi-parametric technique that allows for the quantification of the resting oxygen extraction fraction (OEF), the absolute rate of cerebral metabolic oxygen consumption (CMRO2), cerebral vascular reactivity (CVR) and baseline perfusion (CBF). It combines measurements of arterial spin labelling (ASL) and blood oxygenation level dependent (BOLD) signal changes during hypercapnic and hyperoxic gas challenges. Here we propose an extension to this methodology that permits the simultaneous quantification of the effective oxygen diffusivity of the capillary network (DC). The effective oxygen diffusivity has the scope to be an informative biomarker and useful adjunct to CMRO2, potentially providing a non-invasive metric of microvascular health, which is known to be disturbed in a range of neurological diseases. We demonstrate the new method in a cohort of healthy volunteers (n = 19) both at rest and during visual stimulation. The effective oxygen diffusivity was found to be highly correlated with CMRO2 during rest and activation, consistent with previous PET observations of a strong correlation between metabolic oxygen demand and effective diffusivity. The increase in effective diffusivity during functional activation was found to be consistent with previously reported increases in capillary blood volume, supporting the notion that measured oxygen diffusivity is sensitive to microvascular physiology. PMID- 30278215 TI - Longitudinal changes in serum vitamin D binding protein and free 25 hydroxyvitamin D in a multiracial cohort of pregnant adolescents. AB - Serum free 25-hydroxyvitamin D (25(OH)D) rather than total 25(OH)D may better indicate vitamin D status during pregnancy given the pregnancy-associated increase in serum vitamin D binding protein (DBP) concentration. Our aims were to assess changes in DBP and free 25(OH)D across gestation and to determine whether free compared with total 25(OH)D more strongly correlates with markers of vitamin D and calcium metabolism during pregnancy. This ancillary study included 58 pregnant adolescents (53% African American, 47% White) who completed a vitamin D3 supplementation study in Rochester, NY. Blood was collected at entry, mid-study, and delivery (median 17, 29, and 40 weeks' gestation). Mixed-effects regression was used to test for differences in DBP, directly measured free 25(OH)D, and other serum markers by study visit and race. Free and total 25(OH)D were evaluated in relation to serum PTH, 1,25(OH)2D, 24,25(OH)2D, and calcium. The mean DBP concentration was above nonpregnant reference values at entry and increased across gestation (P < 0.0001). Total 25(OH)D explained most of the variance in free 25(OH)D (r >= 0.67; P < 0.0001). Holding total 25(OH)D constant, each 100 mg/L increase in DBP was associated with a 0.4 pg/mL decrease in free 25(OH)D (P < 0.01). The percent free 25(OH)D was inversely related to both DBP and total 25(OH)D at each visit. Regardless of race or visit, total 25(OH)D was a stronger correlate of PTH, 1,25(OH)2D, and 24,25(OH)2D, and neither total nor free 25(OH)D was related to serum calcium. African Americans had lower total 25(OH)D (P < 0.0001), but free 25(OH)D did not significantly differ by race (P = 0.2). In pregnant adolescents, DBP concentration was elevated and inversely associated with percent free 25(OH)D, but measured free 25(OH)D provided no advantage over total 25(OH)D as a predictor of PTH, 1,25(OH)2D, 24,25(OH)2D, or calcium. The clinical relevance of the small racial difference in percent free 25(OH)D requires further investigation. PMID- 30278216 TI - Ligand chirality can affect histidine protonation of vitamin-D receptor: ab initio molecular orbital calculations in water. AB - Vitamin D is recognized to play important roles in the onset of immunological diseases as well as the regulation of the amount of Ca in the blood. Since these physiological actions caused by active vitamin D are triggered by the specific interaction between the vitamin D receptor (VDR) and active vitamin D, many types of compounds have been developed as potent ligands against VDR. It was found that the binding affinity between VDR and its ligand depends significantly on the chirality of the ligand. However, the reason for the dependence has, thus far, not been elucidated. In the present study, we investigated the specific interactions between VDR and some ligands with different chirality, using ab initio fragment molecular orbital (FMO) calculations. The FMO results reveal that two histidine residues of VDR contribute significantly to the binding between VDR and ligand and that their protonation states can affect the specific interactions between VDR and ligand. We therefore considered other possible protonation states of these histidine residues and determined their most stable states, using the ab initio FMO calculations. The results illustrate the possibility that the difference in the chirality of a ligand can induce the change in protonation states of the histidine residues of VDR existing near the ligand. This finding provides an important warning that the protonation states of histidine residues existing near the ligand should be considered more precisely in the molecular simulations for investigating the specific interactions between protein and ligand. PMID- 30278217 TI - Bioimpedance analysis as an indicator of muscle mass and strength in a group of elderly subjects. AB - OBJECTIVE: To assess the association between whole-body and calf impedance vectors and muscle mass and strength in a group of elderly individuals. MATERIAL AND METHODS: We carried out a cross-sectional observational study on a sample of 113 elderly people. Anthropometric parameters (weight, height and body circumferences) were determined. Body composition was evaluated using conventional bioimpedance analysis (BIA) and vector bioimpedance analysis (BIVA) (whole-body and calf BIVAs), and muscle strength was determined (manual dynamometry). The results were analyzed using the Student t-test or the Mann Whitney U, and the correlations using the Pearson or Spearman test. To compare BIVA results among the subgroups established, the Mahalanobis distance (dM) was calculated and the Hotelling T2 statistic was used. Statistical significance was set to p < 0.05. RESULTS: Nearly half the sample was overweight. Based on waist circumference, 66.7% of the males and 94.9% of the females showed risk of metabolic complications; calf circumference indicated no risk of disability or skeletal muscle mass depletion. However, BIA and dynamometry detected risk of sarcopenia in more than half the subjects. Whole-body BIVA results agreed with those of the BIA, given that most impedance vectors in both sexes were to the right of major axis of the tolerance ellipses. This shows cell mass depletion. While the whole-body BIVA distinguished the subjects having loss of muscle mass and strength, the specific BIVA (calf) only did so in individuals with muscle mass loss. CONCLUSIONS: Whole-body BIVA detects loss of muscle mass and strength, while calf BIVA only distinguishes subjects having muscle mass loss. The localized BIVA might be an alternative to conventional BIA or whole-body BIVA to assess body composition in the elderly. PMID- 30278219 TI - Prevalence, severity and explanatory factors of tooth wear in Arab populations. AB - OBJECTIVES: The aim of this study was to assess the prevalence and severity of tooth wear and related risk indicators in six Arab countries. METHODS: This multicenter, multinational cross-sectional study was conducted among 2924 participants between the ages of 18-35 years old from six Arab countries. Calibrated dentists assessed tooth wear using the Basic Erosive Wear Examination Index (BEWE). Participants were also asked to complete a questionnaire that assessed their dietary and oral health habits. Each participant was identified by the sextant with the highest BEWE score in the upper and lower jaws. RESULTS: Odds ratios were estimated for correlates of tooth wear anterior and posterior regions. Oman had the highest prevalence of BEWE score 3 (N = 255 (60.2%)). Overall, the highest BEWE score 3 was observed on the incisal edge of the upper anterior teeth (N = 602 (20.6%)) and in the lower left posterior region (sextant 6) on the occlusal surface (N = 466 (15.9%)). Correlates of severe tooth wear in both regions were eating or drinking more than six times per day, age and education. Drinking soft drinks "once a day" was significantly associated with severe tooth wear in the posterior region (OR: 1.3, 95% CI:1.05, 1.6). Brushing teeth more than twice a day was inversely associated with tooth wear in the anterior region (OR:0.75, 95% CI: 0.57,0.97). CONCLUSION: The prevalence of tooth wear in Arab populations is relatively high, specific preventive and therapeutic measures should be developed to target people at higher risk of this condition. CLINICAL SIGNIFICANCE: Tooth wear is now regarded as a significant oral health problems, dentists should advice their patients about dietary and oral health habits that can lead to severe tooth wear. PMID- 30278220 TI - White spot syndrome virus (WSSV) infection impacts intestinal microbiota composition and function in Litopenaeus vannamei. AB - Intestinal microbiota homeostasis is crucial to the health of host. Pathogen invasion results in dynamics of microbiota composition and structure, disrupting their function in maintaining host health. WSSV is the most prevalent viral pathogen and is able to cause extremely high mortality in Litopenaeus vannamei. However, the changes of intestinal microbiota induced by WSSV are yet to be elucidated. In this study, we analyzed and compared the microbiota of healthy and WSSV-challenged shrimp intestines. Though the richness and diversity of microbiota was barely affected by WSSV, the abundance of predominant phyla like Proteobacteria and Fusobacteria were upregulated significantly, while Bacteroidetes and Tenericutes were significantly decreased in WSSV-infected shrimps. At the genus level, significant increase was observed in Photobacterium, Propionigenium and Arcobacter, as well as significant decrease in Candidatus Bacilloplasma and Flavobacterium in WSSV-infected shrimps. Additionally, metagenomic predictions by PICRUSt suggested that the altered microbiota was mainly related to metabolism, human diseases, genetic information processing, environmental information processing and cellular processes. These results suggested that the invasion of WSSV could impact intestinal microbiota composition and function in L. vannamei. PMID- 30278218 TI - Sequence-based HLA-A, B, C, DP, DQ, and DR typing of 496 adults from San Diego, California, USA. AB - DNA sequence-based typing at the HLA-A, -B, -C, -DPB1, -DQA1, -DQB1, and -DRB1 loci was performed on 496 healthy adult donors from San Diego, California, to characterize allele frequencies in support of studies of T cell responses to common allergens. Deviations from Hardy Weinberg proportions were detected at each locus except A and C. Several alleles were found in more than 15% of individuals, including the class II alleles DPB1*02:01, DPB1*04:01, DQA1*01:02, DQA1*05:01, DQB1*03:01, and the class I allele A*02:01. Genotype data will be available in the Allele Frequencies Net Database (AFND 3562). PMID- 30278221 TI - PARP inhibition in platinum-based chemotherapy: Chemopotentiation and neuroprotection. AB - Cisplatin, carboplatin and oxaliplatin represent the backbone of platinum therapy for several malignancies including head and neck, lung, colorectal, ovarian, breast, and genitourinary cancer. However, the efficacy of platinum-based drugs is often compromised by a plethora of severe toxicities including sensory and enteric neuropathy. Acute and chronic neurotoxicity following platinum chemotherapy is a major constraint, contributing to dose-reductions, treatment delays, and cessation of treatment. Identifying drugs that effectively prevent these toxic complications is imperative to improve the efficacy of anti-cancer treatment and patient quality of life. Oxidative stress and mitochondrial dysfunction have been highlighted as key players in the pathophysiology of platinum chemotherapy-induced neuropathy. Inhibition of poly(ADP-ribose) polymerase (PARP), a nuclear enzyme activated upon DNA damage, has demonstrated substantial sensory and enteric neuroprotective capacity when administered in combination with platinum chemotherapeutics. Furthermore, administration of PARP inhibitors alongside platinum chemotherapy has been found to significantly improve progression-free survival in patients with breast and ovarian cancer when compared to those receiving chemotherapy alone. This review summarises the current knowledge surrounding mitochondrial damage and oxidative stress in platinum chemotherapy-induced neuropathy and highlights a potential role for PARP in chemopotentiation and neuroprotection. PMID- 30278222 TI - Challenges in allergy immunology practice. PMID- 30278223 TI - Targeting intrinsically disordered proteins at the edge of chaos. AB - Intrinsically disordered proteins or intrinsically disordered regions (IDPs or IDRs) are those that do not fold into defined tertiary structures under physiological conditions. Given their prevalence in various diseases, IDPs are attractive therapeutic targets. However, because of the dynamic nature of the IDP structure, conventional structure-based drug design methods cannot be directly applied. Thanks to recent progress in understanding the mechanisms underlying IDP and ligand interactions, computational strategies for IDP-targeted rational drug discovery are emerging. Here, we summarize recent developments in computational IDP drug design strategies and their successful applications, analyze the typical properties of reported IDP-binding compounds (iIDPs), and discuss the major challenges ahead as well as possible solutions. PMID- 30278224 TI - Basic and practical concepts of radiopharmaceutical purification methods. AB - The presence of radiochemical impurities in a radiopharmaceutical contributes to an unnecessary radiation burden for the patients or to an undesirable high radioactivity background, which reduces the imaging contrast or therapeutic efficacy. Therefore, if the radiolabeling process results in unsatisfactory radiochemical purity, a purification step is unavoidable. A successful purification process requires a profound knowledge about the radiopharmaceuticals of interest ranging from structural features to susceptibility to different conditions. Most radiopharmaceutical purification methods are based on solid phase extraction (SPE), high-performance liquid chromatography (HPLC), size exclusion chromatography (SEC), ion-exchange chromatography (IEC), and liquid liquid extraction (LLE). Here, we discuss the basic and applied concepts of these purifications methods as well as their advantages and limitations. PMID- 30278226 TI - The Mediator complex and the role of protein-protein interactions in the gene regulation machinery. AB - At the core of gene regulation, a complex network of dynamic interactions between proteins, DNA and RNA has to be integrated in order to generate a binary biological output. Large protein complexes, called adaptors, transfer information from the transcription factors to the transcription machinery [1,2]. Here we focus on Mediator, one of the largest adaptor proteins in humans [3]. Assembled from 30 different subunits, this system provides extraordinary illustrations for the various roles played by protein-protein interactions. Recruitment of new subunits during evolution is an adaptive mechanism to the growing complexity of the organism. Integration of information happens at multiple scales, with allosteric effects at the level of individual subunits resulting in large conformational changes. Mediator is also rich in disordered regions that increase the potential for interactions by presenting a malleable surface to its environment. Potentially, 3000 transcription factors can interact with Mediator and so understanding the molecular mechanisms that support the processing of this overload of information is one of the great challenges in molecular biology. PMID- 30278227 TI - Hypoxia-induced autophagy promotes EGFR loss in specific cell contexts, which leads to cell death and enhanced radiosensitivity. AB - Treatment failure through radioresistance of tumors is associated with activation of the epidermal growth factor receptor (EGFR). Tumor cell proliferation, DNA repair, hypoxia and metastases-formation are four mechanisms in which EGFR signaling has an important role. However, the effect of hypoxia on EGFR expression is still controversial. In this study, we demonstrated that hypoxia enhanced EGFR expression and sustained cell survival in SiHa, CAL 27 and A549 cells at both low and high cell desnities, while in MCF-7, MDA-MB-231 and HeLa cells, EGFR and cell survival were regulated by hypoxic treatment in a cell density dependent manner: upregulated at low cell density and downregulated at high cell density. In MCF-7 and HeLa xenografts in nude mice, EGFR expression varied inversely with the pimonidazole level that was used as an indicator of hypoxia, accordant with the effect of hypoxia at high cell density in vitro. Hypoxia induced more remarkable cell autophagy at high cell density than at low cell density. Autophagy inhibitor 3 MA, rather than proteasome inhibitor MG132 inhibited hypoxia-mediated EGFR loss and shifted cell death to cell survival in HeLa cells. The MCF7 cells' sensitivity to ionizing radiation (IR) under hypoxia was also conditional on the cell densities when the hypoxia treatment was introduced, inversely associated with the expression levels of EGFR. Altogether, hypoxia can decrease EGFR expression in some cell lines by enhancing autophagy at high cell density, leading to cell death and hypersensitivity to radiotherapy. This study may help to understand how hypoxia influences EGFR expression and radiosensitivity. PMID- 30278225 TI - Ubiquitin-dependent protein degradation at the endoplasmic reticulum and nuclear envelope. AB - Numerous nascent proteins undergo folding and maturation within the luminal and membrane compartments of the endoplasmic reticulum (ER). Despite the presence of various factors in the ER that promote protein folding, many proteins fail to properly fold and assemble and are subsequently degraded. Regulatory proteins in the ER also undergo degradation in a way that is responsive to stimuli or the changing needs of the cell. As in most cellular compartments, the ubiquitin proteasome system (UPS) is responsible for the majority of the degradation at the ER-in a process termed ER-associated degradation (ERAD). Autophagic processes utilizing ubiquitin-like protein-conjugating systems also play roles in protein degradation at the ER. The ER is continuous with the nuclear envelope (NE), which consists of the outer nuclear membrane (ONM) and inner nuclear membrane (INM). While ERAD is known also to occur at the NE, only some of the ERAD ubiquitin ligation pathways function at the INM. Protein degradation machineries in the ER/NE target a wide variety of substrates in multiple cellular compartments, including the cytoplasm, nucleoplasm, ER lumen, ER membrane, and the NE. Here, we review the protein degradation machineries of the ER and NE and the underlying mechanisms dictating recognition and processing of substrates by these machineries.

AB - STUDY OBJECTIVES: In the US, 40% of high-school students have sex; few use highly effective and safe long-acting reversible contraceptives (LARCs): intrauterine devices (IUDs) and implants. Pediatricians are key health providers for many adolescents, yet few provide LARC. Our objective was to understand the pragmatics of provision of LARC (rather than beliefs or attitudes) and identify barriers to and opportunities for LARC provision by community-practicing pediatricians. DESIGN: We conducted a qualitative descriptive study with semi-structured interviews; qualitative methods are valuable for generating conceptual models of complex phenomena. SETTING: Set in a mid-sized Midwestern city, our study was community-based. PARTICIPANTS: We interviewed 23 pediatricians to understand their views about providing contraception (including LARC) to adolescents. For analysis, we developed a coding schema and applied it using a priori and open coding. RESULTS: Several interrelated themes regarding challenges to provision of LARC emerged: limited motivation for onsite LARC provision or referral streams, low pediatric patient interest in LARC, lack of pediatrician training about LARC provision, and inadequate structural elements for onsite placement of LARC in pediatric offices. Each challenge could be remedied, as pediatricians were motivated to provide adolescent patients with high quality care. Improvements in these interrelated conditions could facilitate pediatrician provision of LARC. CONCLUSION: Pediatricians and their patients want to prevent pregnancy, but current practice norms limit LARC provision by pediatricians. To increase LARC access in pediatrician offices, we suggest training in LARC provision and patient education for medical students, residents, and pediatricians; communicating about LARC methods with adolescents to increase patient demand; and systemic changes to improve referral processes and/or allow on-site LARC placements. PMID- 30278229 TI - Burkitt Lymphoma Presenting as Menorrhagia and a Vaginal Mass in an Adolescent. AB - BACKGROUND: Menorrhagia is a common gynecologic complaint among adolescents, which rarely is secondary to malignancy. Burkitt lymphoma can mimic gynecologic malignancy, however it is rarely seen in adolescents. Burkitt lymphoma of the gynecologic tract requires early diagnosis and intervention for optimal outcomes. CASE: We report a case of a 15-year-old adolescent who had multiple admissions for menorrhagia that was thought to be secondary to anovulatory bleeding until pelvic ultrasound revealed a large 8-cm vaginal/cervical mass. Histologic examination of the biopsy specimen revealed Burkitt lymphoma, which was treated with chemotherapy leading to resolution of her menorrhagia. SUMMARY AND CONCLUSION: Burkitt lymphoma presenting as a vaginal/cervical mass is exceedingly rare, especially in the adolescent patient. Burkitt lymphoma is generally highly responsive to chemotherapy, and symptoms rapidly improve after initiation of treatment.

As a consequence, the use of electrophysiological studies (EPS) in clinical practice has also significantly augmented, with a progressively increasing number of certified electrophysiology centers and specialists. Since Zipes et al published the Guidelines for Clinical Intracardiac Electrophysiology and Catheter Ablation Procedures in 1995, no official document summarizing current EPS indications has been published. PMID- 30278231 TI - Mechanisms of isolevuglandin-protein adduct formation in inflammation and hypertension. AB - Inflammation has been implicated in the pathogenesis of hypertension and recent evidence suggests that isolevuglandin (IsoLG)-protein adducts play a role. Several hypertensive stimuli contribute to formation of IsoLG-protein adducts including excess dietary salt and catecholamines. The precise intracellular mechanisms by which these hypertensive stimuli lead to IsoLG-protein adduct formation are still not well understood; however, there is now evidence implicating NADPH-oxidase derived reactive oxygen species (ROS) in this process. ROS oxidize arachidonic acid leading to formation of IsoLGs, which non-covalently adduct to lysine residues and alter protein structure and function. Recent studies suggest that these altered proteins act as neo-antigens leading to an autoimmune state that results in hypertension. The goal of this mini-review is to highlight some of the hypertensive stimuli and the mechanisms contributing to IsoLG-protein adduct formation leading to inflammation and hypertension. PMID- 30278232 TI - The Non-Avoidant Pacing Scale: Development and Preliminary Validation. AB - Despite widespread use as a chronic pain management strategy, pacing has been linked with higher levels of pain and disability. A recent meta-analysis found a positive correlation between existing measures of pacing and avoidance, which may partially account for these poorer outcomes. A measure was developed to differentiate pacing from avoidance by emphasizing non-pain-contingent pacing behaviors and nonavoidance of pain. A sample of 283 adults with chronic pain completed the Non-Avoidant Pacing Scale (NAPS) and existing measures of pacing, avoidance, pain, and physical and psychological functioning. Exploratory factor analysis of 10 items (subsample 1, n = 141) suggested two 4-item factors: planned pacing behaviors and pacing through flare ups. Confirmatory factor analysis of 8 items (subsample 2, n = 142) revealed satisfactory fit (goodness-of-fit index .947, comparative fit index .964). The pattern of correlations between each factor and avoidance and key outcomes suggests that the NAPS total scale (alpha = .819) captures key pacing behaviors and differentiates pacing from avoidance. Unlike existing measures, the NAPS was not positively correlated with avoidance and was associated with better psychological functioning across affective and cognitive domains. The NAPS allows researchers and clinicians to assess the role of pacing in chronic pain management without artefactual overlap with avoidance. PERSPECTIVE: The NAPS assesses activity pacing in chronic pain without artefactual overlap with avoidance. Associations were found between more frequent pacing, as measured by the NAPS, and better psychological functioning. Clearly differentiating pacing from avoidance allows for accurate assessment of the role of pacing in chronic pain management. PMID- 30278233 TI - Laparoendoscopic Single-site Surgery for Comprehensive Staging of Early Ovarian Cancer. AB - STUDY OBJECTIVE: To demonstrate the procedure and suspension skills of laparoendoscopic single-site (LESS) staging surgery with infrarenal para-aortic lymphadenectomy for early-stage ovarian cancer. DESIGN: A presentation of the surgery through this technical video. SETTING: A hospital. PATIENT AND INTERVENTIONS: A 45-year-old woman presented with a pelvic mass on gynecologic examination and a serum cancer antigen 125 level of 5910 U/mL (normal = <35 U/mL). A computed tomographic scan revealed a mixture of solid and cystic components (70 * 77 * 71 mm) arising from the right ovary and characterized by the "ovarian vascular pelvic" sign. Clinically early-stage ovarian cancer was suspected. Subsequently, LESS staging surgery was performed by an experienced surgeon in our department. RESULTS: The surgery lasted 280 minutes, and the volume of blood loss was 50 mL; there were no intra- or postoperative complications. We "hid" the incision perfectly for cosmetic purposes. The histopathologic findings supported high-grade serous ovarian cancer of the right ovary with the left fallopian tube involved as well. In addition, a total of 34 negative pelvic and 18 negative para-aortic lymph nodes were identified, and a stage of IIA was diagnosed as a result. CONCLUSION: We performed an LESS staging surgery for early-stage ovarian cancer successfully. Our video shows that the LESS approach provided feasible, cosmetic, and safe access among the selected malignant gynecologic surgery. Therefore, we have experienced that the effective suspension was an auxiliary measure for LESS lymphadenectomy. In addition, compared with multiport laparoscopy, the LESS approach could provide easier access to infrarenal para-aortic regions; furthermore, it was safe and quick to extract an unknown sample. PMID- 30278234 TI - Bladder Endometriosis: Management by Cystoscopic and Laparoscopic Approaches. AB - STUDY OBJECTIVE: Endometriosis of the urinary system accounts for less than 1% of all endometriosis, wherein bladder endometriosis is the most common. Bladder endometriosis is defined as endometriosis infiltrating the detrusor muscle and represents 85% of urinary tract endometriosis [1,2]. Segmental bladder resection/partial cystectomy is the bladder-preserving surgery and offers the complete removal of bladder endometriotic nodules [3,4]. Laparoscopic/robotic excision increases the chances of complete removal of nodules but may lead to inadvertent removal of excess bladder wall and increase the risk of complications, especially in cases of large lesions in close proximity to ureteric orifices. Thus, simultaneous laparoscopy and cystoscopy offers the most effective way of complete resection of bladder endometriotic nodules, relieving symptoms and minimizing intraoperative and postoperative complications and recurrence rates in patients [5-11]. This article with accompanying video describes the systematic approach and step-by-step surgical excision of a bladder endometriotic nodule in a patient with frozen pelvis. DESIGN: Step-by-step surgical excision of a bladder endometriotic nodule by simultaneous cystoscopy and laparoscopy. (Canadain Task Force classification: level III) SETTING: Jyoti Hospital and Minimum Invasive Surgery Center, Ahmedabad, India. PATIENT: A 41 year-old women, P2L2, presented with cyclical dysmenorrhea, dysuria, and chronic pelvic pain. Informed consent was obtained from the patient, and the local institutional board provided the approval. INTERVENTION: Simultaneous cystoscopy and laparoscopy. MEASUREMENTS AND MAIN RESULTS: A preoperative assessment was done with transvaginal ultrasonography with a partially full bladder that showed an intravesical 3-cm endometriotic nodule along with chocolate cysts of the ovary and adenomyosis of the uterus. A simultaneous cystoscopy by a urologist and laparoscopy by a gynecologist was performed. On cystoscopy the nodule was seen away from both the ureteric orifices. The nodule was marked cystoscopically with a monopolar needle and laparoscopically with bipolar scissors. Laparoscopy began with a full inspection of the abdomen, pelvis, and adhesions. Dissection started from the left round ligament, and both paravesical spaces were dissected gently, keeping the bladder partially full. Good uterine manipulation helped to delineate vaginal fornices during dissection. Dissection continued over the isthmus, and bladder was gently separated from the isthmus. The bladder was partially filled with methylene blue and intentionally cut opened to excise the demarcated bladder nodule with a monopolar hook, taking a disease-free margin of 5 mm [12]. Two stay sutures were taken at both the lateral angles of the bladder, and suture ends were brought outside the abdomen to facilitate closure of the bladder transversely. After mobilization of the bladder, both uterine vascular bundles were desiccated with bipolar and laparoscopic hysterectomy. Vaginal closure was done away from bladder stitches. The patient was discharged on day 3 with catheter and DJ stents. On day 21, 3-dimensional computed tomography cystogram showed adequate bladder volume. Catheter and DJ stents were removed, low-pressure cystoscopy showed a smooth stitch line with mucosa over it and no residual endometriosis. The patient was found to have no symptoms at the 2-year follow up. CONCLUSION: The video demonstrates the feasibility of simultaneous laparoscopic and cystoscopic approach for excision of a bladder endometriotic nodule. Marking the nodule by simultaneous cystoscopy and laparoscopy before excision helps in removing the disease completely and avoiding unnecessary normal bladder wall excision, thus reducing the risk of recurrence and resultant small bladder symptoms.

PMID- 30278237 TI - Disease-related outcomes influence prevalence of falls in people with rheumatoid arthritis. AB - BACKGROUND: Patients with rheumatoid arthritis (RA) are at increased risk of falls, with potential adverse outcomes. There is a considerable variation across studies regarding the prevalence of falls and its correlation with clinical data, disease-related outcomes and physical performance tests. OBJECTIVE: The aim of this study was to evaluate the prevalence of falls and its association with clinical data, disease-related outcomes and physical performance tests. METHODS: In this cross-sectional study, 113 RA patients were divided into 3 groups - "non fallers", "sporadic fallers" and "recurrent fallers" - and compared in terms of clinical data, Clinical Disease Activity Index (CDAI), lower-limb tender and swollen joint count, disability (Health Assessment Questionnaire-Disability Index [HAQ-DI]), Foot Function Index (FFI), Berg Balance Scale (BBS), Timed-up-and-go Test (TUG) and 5-Time Sit Down-To-Stand Up Test (SST5). Logistic regression analysis was performed to analyze the associations between the studied variables and the occurrence of falls, estimating odds ratios (ORs). We also analyzed the correlation between disease outcome measures (HAQ-DI and CDAI) and physical tests (BBS, TUG, SST5). RESULTS: Falls and fear of falling were reported by 59 (52.21%) and 71 (64.5%) patients, respectively. Significant associations were found between "recurrent fallers" and vertigo (OR=3.42; P=0.03), fear of falling (OR=3.44; P=0.01), low income (OR=2.02; P=0.04), CDAI (OR=1.08; P<0.01), HAQ-DI (OR=3.66; P<0.01), Lower-limb HAQ (OR=3.48; P<0.01), FFI-pain (OR=1.24; P=0.03), FFI-total (OR=1.23; P=0.04), lower-limb tender joint count (OR=1.22; P<0.01), BBS score (OR=1.14; P<0.01), TUG score (OR=1.13; P=0.03) and SST5 score (OR=1.06; P=0.02). On multivariate analysis, CDAI was the only significant predictor of recurrent falls (OR=1.08; P<0.01). Physical performance test scores (BBS, TUG, SST5) were correlated with the CDAI and HAQ-DI. CONCLUSION: The prevalence of falls in RA is high, most influenced by disease-related outcomes and linked to worse performance on physical tests (BBS, TUG and SST5). PMID- 30278238 TI - Are probiotics and prebiotics effective in the prevention of travellers' diarrhea: A systematic review and meta-analysis. AB - BACKGROUND: Travellers' diarrhea (TD) impacts annually over 20 million tourists, business travellers and military troops on a worldwide basis. Reliance on antibiotic prophylaxis and educational programs has not lead to a significant reduction in TD rates. Previous reviews of probiotics for TD have not accounted for the strain-specificity of probiotic efficacy nor have investigated prebiotics for the prevention of TD. METHODS: Standard literature databases were searched from 1977 to June 2018 unrestricted by language. Inclusion criteria included: Probiotic, probiotic or symbiotic interventions, randomized, controlled clinical trials (RCTs) and >=2 RCTs with the same probiotic strain or mixture. RESULTS: Of 158 screened articles, 12 RCT were included in the systematic review and 6 RCTs (with nine treatment different arms) were included in the meta-analysis. Saccharomyces boulardii CNCM I-745 showed a significant reduction in TD incidence (RR = 0.79, 95% C.I. 0.72-0.87, p < 0.001), while L. rhamnosus GG showed a trend (p = 0.08) and L. acidophilus showed no significant (p = 0.16) reduction of TD. CONCLUSIONS: The number of trials using probiotics or prebiotics for the prevention of TD continues to be limited in number. Only one of three probiotics showed significant efficacy for the prevention of TD. More research is needed for other probiotics strains and prebiotics to determine if they could also prevent TD. PMID- 30278239 TI - Modulating alpha-synuclein fibril formation using DNA tetrahedron nanostructures. AB - The small presynaptic protein alpha-synuclein (alpha-syn) is involved in the etiology of Parkinson's disease owing to its abnormal misfolding. To date, little information is known on the role of DNA nanostructures in the formation of alpha syn amyloid fibrils. Here, the effects of DNA tetrahedrons on the formation of alpha-syn amyloid fibrils were investigated using various biochemical and biophysical methods such as thioflavin T fluorescence assay, atomic force microscopy, light scattering, transmission electron microscopy, and cell-based cytotoxicity assay. It has been shown that DNA tetrahedrons decreased the level of oligomers and increased the level of amyloid fibrils, which corresponded to decreased cellular toxicity. The ability of DNA tetrahedron to facilitate the formation of alpha-syn amyloid fibrils demonstrated that structured nucleic acids such as DNA tetrahedrons could modulate the process of amyloid fibril formation. Our study suggests that DNA tetrahedrons could be used as an important facilitator toward amyloid fibril formation of alpha-synuclein, which may be of significance in finding therapeutic approaches to Parkinson's disease and related synucleinopathies. PMID- 30278240 TI - Is CYP1B1 involved in the metabolism of dioxins in the pig? AB - 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is the most difficult to biodegradate and the most toxic dioxin congener. Previously, we demonstrated in silico the ability of pig CYP1A1 to hydroxylate 2,7-dichlorodibenzo-p-dioxin (DiCDD), but not TCDD. To increase our knowledge concerning the low effectiveness of TCDD biodegradability, we analyzed in silico the binding selectivity and affinity between pig CYP1B1 and the two dioxins by means of molecular modeling. We also compared the effects of TCDD and DiCDD on CYP1B1 gene expression (qRT-PCR) and catalytic (EROD) activity in porcine granulosa cells. It was found that DiCDD and TCDD were stabilized within the pig CYP1B1 active site by hydrophobic interactions. The analysis of substrate channel availability revealed that both dioxins opened the exit channel S, allowing metabolites to leave the enzyme active site. Moreover, DiCDD and TCDD increased the CYP1B1 gene expression and catalytic activity in porcine granulosa cells. On the other hand, TCDD demonstrated higher than DiCDD calculated affinity to pig CYP1B1, hindering TCDD exit from the active site. The great distance between CYP1B1's heme and TCDD also might contribute to the lower hydroxylation effectiveness of TCDD compared to that of DiCDD. Moreover, the narrow active site of pig CYP1B1 may immobilize TCDD molecule, inhibiting its hydroxylation. The results of the access channel analysis and the distance from pig CYP1B1's heme to TCDD suggest that the metabolizing potential of pig CYP1B1 is higher than that of pig CYP1A1. However, this potential is probably not sufficiently high to considerably improve the slow TCDD biodegradation. PMID- 30278241 TI - Insulin-like growth factor type I selectively binds to G-quadruplex structures. AB - BACKGROUND: G-quadruplex has been viewed as a promising therapeutic target in oncology due to its potentially important roles in physiological and pathological processes. Emerging evidence suggests that the biological functions of G quadruplexes are closely related to the binding of some proteins. Insulin-like growth factor type I (IGF-1), as a significant modulator of cell growth and development, may serve as a quadruplex-binding protein. METHODS: The binding affinity and selectivity of IGF-1 to different DNA motifs in solution were measured by using fluorescence spectroscopy, Surface Plasmon Resonance (SPR), and force-induced remnant magnetization (FIRM). The effects of IGF-1 on the formation and stability of G-quadruplex structures were evaluated by circular dichroism (CD) and melting fluorescence resonance energy transfer (FRET) spectroscopy. The influence of quadruplex-specific ligands on the binding of G-quadruplexes with IGF-1 was determined by FIRM. RESULTS: IGF-1 shows a binding specificity for G quadruplex structures, especially the G-quadruplex structure with a parallel topology. The quadruplex-specific ligands TMPyP4 and PDS (Pyridostatin) can inhibit the interaction between G-quadruplexes and proteins. CONCLUSIONS: IGF-1 is demonstrated to selectively bind with G-quadruplex structures. The use of quadruplex-interactive ligands could modulate the binding of IGF-1 to G quadruplexes. GENERAL SIGNIFICANCE: This study provides us with a new perspective to understand the possible physiological relationship between IGF-1 and G quadruplexes and also conveys a strategy to regulate the interaction between G quadruplex DNA and proteins. PMID- 30278242 TI - Metabolism and disposition of arsenic species from controlled dosing with sodium arsenite in adult female CD-1 mice. III. Toxicokinetic studies following oral and intravenous administration. AB - Arsenic is a ubiquitous contaminant, with typical dietary intake below 1 MUg/kg bw/d and drinking water exposures up to 50 MUg/kg bw/d. Arsenic exposures are associated with human diseases and doses of toxicological concern are similar to typical dietary intake. Metabolism of arsenite to dimethylarsinate (DMAV) by arsenite-3-methyltransferase (As3MT) promotes clearance, but also generates reactive trivalent intermediates that bind extensively to cellular thiols. This study measured pentavalent and trivalent arsenic species in blood and tissues after oral and intravenous administration of arsenite (50 MUg/kg bw). After oral administration, the intestine and liver contained elevated levels of AsIII and MMAIII, relative to erythrocytes, lung, and kidney, suggesting incomplete conversion to DMA during first-pass metabolism. However, blood concentrations of the predominant species, DMA, were similar for oral and intravenous dosing. While all tissues examined contained DMAIII, muscle, brain, and plasma had undetectable levels of MMAIII. Tissue levels of arsenic species were similar following intravenous vs. oral administration, except lower in the intestine. The results confirm the role of metabolism in producing fluxes of putatively toxic trivalent arsenic intermediates. Tissue dosimetry suggests that the intestine, liver, lung, and kidney could be more susceptible to effects of bound arsenic, relative to muscle and brain. PMID- 30278243 TI - Preliminary assessment of galaxolide bioaccessibility in raw and cooked FISH. AB - Generally, dietary intake assessment and risk characterization are evaluated using contaminant concentration in raw fish while it is usually ingested cooked, which can cause an overestimation because one of the essential issues for risk benefit analysis is to determine the maximum amount of a contaminant that can be released from the food matrix and be absorbed by the human body, called bioaccessibility. Moreover, despite most seafood products are cooked before consumption, risk assessment is still evaluated in raw products, strongly affecting public health guidelines. In the present study, an in vitro bioaccessibility assay was performed for Galaxolide (HHCB) in fish samples. Raw spiked hake samples were in vitro digested and aliquots of each fraction of the digestion process were analysed. HHCB was quantitatively present in the bioaccessibility fraction. The effect of fish cooking on HHCB was also evaluated in cod and mackerel samples. Results demonstrate that steaming and grilling processes lead to a loss of 50-70% HHCB in fish. PMID- 30278244 TI - Postnatal exposure to chlorpyrifos produces long-term effects on spatial memory and the cholinergic system in mice in a sex- and APOE genotype-dependent manner. AB - Organophosphorus pesticides - and in particular chlorpyrifos (CPF) - are extensively used worldwide. They mainly exert their toxicity by targeting the cholinergic system. Several studies suggested that the gene coding for apolipoprotein E (apoE), which is a risk factor for several diseases, can also confer different vulnerability to toxic insults. This study was aimed at assessing the long-term effects of postnatal exposure to CPF on learning and memory as well as the expression levels of several genes involved in cholinergic neurotransmission in mice. Both male and female apoE4-TR and C57BL/6 mice were exposed to either 0 or 1 mg/kg/day of CPF by oral gavage using a micropipette on postnatal days 10-15. At 9 months, they were tested in a Morris Water Maze (MWM) and the gene expression in the frontal cortex and hippocampus was evaluated. Our results show that, in males, CPF had an effect on the spatial retention, while in females, it altered the expression levels of nicotinic receptors. Furthermore, apoE4-TR mice performed the worst during the MWM retention and presented low expression levels in a considerable number of cholinergic genes. Taken together, the current results reveal long-term effects in mice nine months after postnatal exposure to CPF, which are modulated by sex and apoE4 genotype. PMID- 30278245 TI - Depression-like behaviors induced by chronic corticosterone exposure via drinking water: Time-course analysis. AB - Hypothalamic-pituitary-adrenal (HPA) axis activity is commonly dysregulated in stress-related psychiatric disorders. The corticosterone rat model was developed to understand the influence of stress on depression-like symptomatology. To further understand the effects of corticosterone on the development of depression like behavior, rats were continuously exposed to corticosterone (200 MUg/ml) or vehicle via drinking water daily for 21 days. The rats underwent a series of behavioral tests, and electroencephalographical recordings were performed after 7, 14, and 21 days of treatment. The measurements included immobility time (i.e., despair) in the forced swim test, locomotor activity in the open field test, sucrose consumption (i.e., anhedonia) in the sucrose preference test, and sleep wake parameters. The rats in the 7-day corticosterone exposure group exhibited depression-like behavior, including increases in despair, anhedonia, anxiety, and sleep impairments. The rats in the 14-day corticosterone exposure group exhibited normal patterns of behavior and sleep structure. When corticosterone exposure was extended to 21 days, depression-like symptoms recurred, including despair, anhedonia, anxiety, and sleep disturbances. Overall, the present study observed U shaped depression-like effects across 3 weeks of corticosterone exposure via drinking water. PMID- 30278246 TI - Effect of 5-HT2A receptor antagonist ketanserin on micturition in male rats. AB - OBJECTIVES: This study aimed to investigate the effects of ketanserin on micturition mediated via the 5-HT2A receptor in the motoneuron nucleus of the Lumbosacral cord, as reflected in high frequency oscillations (HFOs) of intravesical pressure and the external urethral sphincter electromyogram (EUS EMG) in anesthetized male rats. METHODS:: Male Sprague-Dawley rats were used. Cystometry and EUS-EMG were performed in all rats under urethane anesthesia to examine the variations after successive intrathecal (i.t.) administration of various doses of ketanserin into the lumbosacral cord. Immunofluorescence staining and Western blotting were made to observe the distribution of 5-HT2 A and -2C receptors in the lumbosacral cord motor neurons. RESULTS: Compared to the controls, ketanserin-treated rats showed a declined trend of dose-dependent manner in the HFOs, in accordance with the variation of EUS-EMG, while decreased micturition volume, voiding efficiency, and increased post-void residual volume was only observed at the dose of 0.1 mg/kg. The effects of ketanserin on the HFO and EUS-EMG activity were partially or completely reversed by the 5-HT2A/2C receptor agonist, DOI. Meanwhile, immunofluorescence staining and Western blot analysis showed that immunoreactivity of 5-HT2A receptor was higher than that of 5-HT2C, labeling in the lumbosacral cord motoneurons. CONCLUSIONS: The intrathecally administrated 5-HT2A receptor antagonist ketanserin can weaken the EUS bursting activity, decrease HFOs, and reduce voiding efficiency as dose dependently. The effects of ketanserin on micturition may be mainly mediated via the 5-HT2A receptors in the motoneuron nucleus of the lumbosacral cord. PMID- 30278247 TI - Association of vascular endothelial growth factor levels in CSF and cerebral glucose metabolism across the Alzheimer's disease spectrum. AB - The association of vascular endothelial growth factor (VEGF) levels in CSF and cerebral glucose metabolism across the Alzheimer's disease (AD) spectrum is unclear. CSF VEGF levels were cross-sectionally related to cerebral glucose metabolism, as measured by 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), using linear regression models. We found that VEGF levels were associated with cerebral glucose metabolism in patients with mild cognitive impairment (MCI) and AD, but not in cognitively normal older adults. Our data indicated that VEGF may play an important role in cerebral glucose metabolism. PMID- 30278248 TI - Anti-neuroinflammatory effects of SLOH in Abeta-induced BV-2 microglial cells and 3xTg-AD mice involve the inhibition of GSK-3beta. AB - Neuroinflammation has been observed in post-mortem Alzheimer's disease (AD) brains which could be due to Abeta interacting with microglia and astrocytes. SLOH, a carbazole-based fluorophore, was shown to bind to Abeta peptides. Herein, we investigated the anti-neuroinflammatory effects of SLOH using a BV-2 microglial cell model and a triple transgenic AD (3xTg-AD) mouse model. BV-2 cells were incubated with Abeta in the presence of SLOH for 24 h. The levels of pro-inflammatory and anti-inflammatory cytokines were determined. Moreover, 3xTg AD mice were administrated with SLOH (2 mg kg-1) for one month. The mice were then sacrificed and the brains were used to assess the levels of pro inflammatory, anti-inflammatory cytokines and the activation of ionized calcium binding adapter molecule 1 (Iba1). BV-2 cell studies suggested that SLOH reduced the production and mRNA levels of pro-inflammatory cytokines TNF-alpha, IL-1beta, COX-2, iNOS, and increased IL-10. Animal study confirmed that SLOH reduced the production of pro-inflammatory cytokines and increased the level of anti inflammatory cytokine. Moreover, SLOH inhibited the activity of GSK-3beta. In 3xTg-AD mouse model, SLOH treatment significantly decreased the number of Iba1 positive cells in mouse brains. Our results demonstrated that SLOH significantly attenuated the neuroinflammation through down-regulating the activity of GSK 3beta. PMID- 30278250 TI - Remaining Puzzles about Morpheme Production in the Posterior Temporal Lobe. AB - Using data from time-resolved cortical stimulation, intracranial neural recordings, and focal surgical resections, Lee et al. (2018) demonstrate that a small area within left posterior superior temporal gyrus (pSTG) supports the ability to produce functional morphemes but not other basic aspects of language production or comprehension. These findings are intriguing because they raise important questions about the functional architecture of language processing, including critically, the relationship between production and comprehension. Here, we highlight some of the puzzles that remain and that we hope will guide future empirical explorations of the cognitive and neural mechanisms that support our capacity for language. PMID- 30278249 TI - Diffusion Kurtosis Imaging Characterizes Brain Microstructural Changes Associated with Cognitive Impairment in a Rat Model of Chronic Traumatic Brain Injury. AB - This study aims to investigate the value of diffusion kurtosis imaging (DKI) in assessing microstructural changes associated with cognitive impairment in chronic traumatic brain injury (TBI). At 7 months, six TBI rats and six control rats underwent Morris water maze (MWM) tests, followed by DKI examinations. DKI parameters were measured in bilateral cortex, hippocampus, and callosum. Brain immunohistochemistry (IHC) analysis of neuron [neuron-specific nuclear protein (NeuN)], astroglia [glial fibrillary acidic protein (GFAP)], microglia [ionized calcium binding adaptor molecule 1 (Iba-1)], and myelin [myelin basic protein (MBP)] was performed in the same area as DKI parameter. The DKI parameters, IHC results, and MWM results were compared between TBI and control groups. Correlation analysis was performed to analyze the relationship between DKI parameters and IHC and MWM results. TBI group had worse performance in MWM test. DKI showed higher mean diffusion (MD) in all ipsilateral regions of interest (ROIs), and lower mean kurtosis (MK) in ipsilateral cortex and callosum in TBI group (P < 0.05). TBI group also showed lower IHC staining of NeuN, and higher staining of Iba-1 and MBP in all ipsilateral ROIs (P < 0.05). Further correlational study showed a positive relationship between MK and NeuN, MD and MBP in ipsilateral cortex, and a negative relationship between MK and Iba-1, MBP in ipsilateral cortex and hippocampus (P < 0.05). The MK in ipsilateral cortex and hippocampus were also correlated with MWM test results (P < 0.05). Our study suggests that DKI could be used to assess the microstructural changes associated with cognitive impairment in chronic TBI.

How alterations in the histamine system lead to neuropsychiatric disease, however, remains unclear. The H3R histamine receptor is elevated in the striatum of Hdc KO mice, and H3R agonists, acting in the dorsal striatum, trigger tic-like movements in the model. In wild-type mice, H3R in the dorsal striatum differentially regulates mitogen activated protein kinase (MAPK) and protein kinase B (Akt) signaling in D1R dopamine receptor-expressing striatonigral medium spiny neurons (dMSNs) and D2R dopamine receptor-expressing striatopallidal MSNs (iMSNs), respectively. We examined the effects of H3R agonist treatment on MSN signaling in the Hdc-KO model. In dMSNs, MAPK signaling was elevated at baseline in the Hdc-KO model, resembling what is seen after H3R activation in WT animals. Similarly, in iMSNs, Akt phosphorylation was reduced at baseline in the KO model, resembling what is seen after H3R activation in WT animals. H3R activation in Hdc-KO mice further enhanced the baseline effect on Akt phosphorylation in iMSNs but attenuated the abnormality in MAPK signaling in dMSNs. These observations support the hypothesis that constitutive activity of upregulated H3R receptors in the Hdc-KO model mediates the observed alterations in baseline MSN signaling; but further activation of H3R, which produces tic-like repetitive movements in the model, has more complex effects. PMID- 30278253 TI - Frogs and tuns and tritons - A molecular phylogeny and revised family classification of the predatory gastropod superfamily Tonnoidea (Caenogastropoda). AB - The Tonnoidea is a moderately diverse group of large, predatory gastropods with ~360 valid species. Known for their ability to secrete sulfuric acid, they use it to prey on a diversity of invertebrates, primarily echinoderms. Tonnoideans currently are classified in seven accepted families: the comparatively well known, shallow water Bursidae, Cassidae, Personidae, Ranellidae, and Tonnidae, and the lesser-known, deep water Laubierinidae and Pisanianuridae. We assembled a mitochondrial and nuclear gene (COI, 16S, 12S, 28S) dataset for ~80 species and 38 genera currently recognized as valid. Bayesian analysis of the concatenated dataset recovered a monophyletic Tonnoidea, with Ficus as its sister group. Unexpectedly, Thalassocyon, currently classified in the Ficidae, was nested within the ingroup as the sister group to Distorsionella. Among currently recognized families, Tonnidae, Cassidae, Bursidae and Personidae were supported as monophyletic but the Ranellidae and Ranellinae were not, with Cymatiinae, Ranella and Charonia supported as three unrelated clades. The Laubierinidae and Pisanianuridae together form a monophyletic group. Although not all currently accepted genera have been included in the analysis, the new phylogeny is sufficiently robust and stable to the inclusion/exclusion of nonconserved regions to establish a revised family-level classification with nine families: Bursidae, Cassidae, Charoniidae, Cymatiidae, Laubierinidae, Personidae, Ranellidae, Thalassocyonidae and Tonnidae. The results reveal that many genera as presently circumscribed are para- or polyphyletic and, in some cases support the rescue of several genus-group names from synonymy (Austrosassia, Austrotriton, Laminilabrum, Lampadopsis, Personella, Proxicharonia, Tritonoranella) or conversely, support their synonymization (Biplex with Gyrineum). Several species complexes are also revealed that merit further investigation (e.g., Personidae: Distorsio decipiens, D. reticularis; Bursidae: Bursa tuberosissima; Cassidae: Echinophoria wyvillei, Galeodea bituminata, and Semicassis bisulcata). Consequently, despite their teleplanic larvae, the apparently circumglobal distribution of some tonnoidean species is the result of excessive synonymy. The superfamily is estimated to have diverged during the early Jurassic (~186 Ma), with most families originating during a narrow ~20 My window in Albian-Aptian times as part of the Mesozoic Marine Revolution. PMID- 30278252 TI - Molecular phylogeny of Chondrocyclus (Gastropoda: Cyclophoridae), a widespread genus of sedentary, restricted-range snails. AB - The genus Chondrocyclus Ancey, 1898 contains the majority of southern African members of the Cyclophoridae, a large family of operculate land snails. We present the first molecular phylogeny of the genus based on two mitochondrial genes (16S and CO1) and complement this with an appraisal of morphological characters relating to the shell and soft parts. Worn shells on which some descriptions and records of different species were based appear to be indistinguishable morphologically, creating taxonomic confusion. We show that Chondrocyclus s.l. underwent two major radiations, one Afromontane and the other largely coastal. Accordingly, we recommend a revision recognising two genera. Chondrocyclus s.s. contains four monophyletic lineages, each characterized by a combination of morphological features. The Afromontane group is shown to be a species complex; relationships within this complex could not be resolved due to insufficient DNA sequence data. The molecular data confirms the monophyly of seven currently recognised species and provides evidence for at least twelve undescribed species; the morphological data are broadly consistent with this finding. The morphological data suggest that the two species from countries to the north of South Africa should be removed from the genus, and that Chondrocyclus sensu lato is endemic to South Africa. The historical biogeography of this group of microhabitat specialists with poor dispersal abilities contributes an additional, phylogenetically independent taxon to our understanding of the processes generating biodiversity in southern Africa, a natural laboratory for palaeobiogeography. All taxa are narrow-range endemics, underlining the importance of conserving South Africa's threatened forest habitats. PMID- 30278254 TI - Unravelling relationships among the shared stripes of sailors: Mitogenomic phylogeny of Limenitidini butterflies (Lepidoptera, Nymphalidae, Limenitidinae), focusing on the genera Athyma and Limenitis. AB - The phylogenetic relationships of the nymphalid butterfly tribe Limenitidini are best known for the genera Limenitis and Adelpha, model taxa for evolutionary processes such as Batesian mimicry and rapid adaptive radiations. Whereas these American limenitidines have received the most attention, phylogenetic relationships of their Asian relatives are still controversial and largely unexplored. Even one of the largest genera in Asia, Athyma, is polyphyletic. To clarify the phylogenetic relationships of these Asian Limenitidini, a total of 53 representatives were sampled; 37 have their mitogenomes sequenced for the first time. Our phylogenetic results confirm that mitogenomic data provides well resolved relationships at most major levels of the phylogeny, even using different partition schemes or different inference methods. Interestingly, our results show that some Athyma taxa are embedded within the genus Limenitis, whereas the genus Tacola, previously considered to be a synonym of Athyma, needs to be recognized as a valid clade. Additionally, the other Limenitidini genera in Asia (namely Tarattia, Litinga, Sumalia, Pandita and Patsuia) are now grouped either within Athyma or Limenitis, so these genera need to be sunk. Importantly, we also show that the mainly Old World Limenitis and entirely New World Adelpha are sister groups, confirming the relevance of Asian lineages to global studies of Limenitis evolution.

AB - Eliminating the infection from root canals and periodontal tissues of human teeth as well as the repair of infected periodontal bone has been a great challenge. Poly(lactide-co-glycolide) (PLGA) particles have been used for drug delivery due to their biodegradability, sustained drug release and nontoxic properties. As silver ions (Ag+) exhibit strong antibacterial ability and calcium ions (Ca2+) are essential for hard tissue regeneration, the Ag+ and Ca2+ were encapsulated into the PLGA particles to form AgCa-PLGA submicron particles. The physico chemical properties, ion release, cytotoxicity, ability to infiltrate dentinal tubules, antibacterial effects against Enterococcus faecalis (E. faecalis) and Porphyromonas gingivalis (P. gingivalis) in either planktonic or biofilm forms on dentin as well as in vitro mineralization ability were investigated. Results showed that Ag+ and Ca2+ were encapsulated into the AgCa-PLGA particles, which could release both Ag+ and Ca2+ over 30 days and exhibited strong antibacterial effects against E. faecalis and P. gingivalis. AgCa-PLGA particles could infiltrate into dentinal tubules by ultrasonic activation and inhibit the colonization of E. faecalis and P. gingivalis on dentin. AgCa-PLGA particles showed no cytotoxicity and induced hydroxyapatite (HA)-like crystal formation. AgCa-PLGA submicron particles could become a biomaterial for both infection control and hard tissue regeneration in dentistry and other related medical areas. PMID- 30278256 TI - Influence of preparation technique on co-amorphization of carvedilol with acidic amino acids. AB - Basic amino acids (AAs) have successfully been used as co-formers with acidic drugs for the preparation of co-amorphous formulations using ball-milling (BM) and spray-drying (SD). In contrast, acidic AAs have been reported as poor co formers for co-amorphous formulations, even for basic drugs, when using BM as a preparation technique. In this study the basic drug carvedilol (CAR) and the two acidic AAs, glutamic acid and aspartic acid, were used to explore the possibilities of producing co-amorphous formulations using BM, SD and liquid assisted grinding (LAG). X-ray powder diffraction, thermal analysis and Fourier transform infrared spectroscopy were used to determine the solid state form of the various CAR-AA mixtures prepared. BM the CAR-AA mixtures for 60 min did not result in co-amorphization as XRPD revealed remaining crystallinity of both CAR and the AA. On the other hand, successful co-amorphous salt formation was obtained for all SD samples. Differential scanning calorimetry showed that all the SD CAR-AA mixtures had a single glass transition temperature of approximately 80 degrees C. The CAR-AA mixtures prepared by LAG showed some polymorphic conversion of CAR. Intrinsic dissolution testing showed the highest dissolution rate for all SD mixtures due to co-amorphous salt formation. Hence it was observed that of the three preparation techniques used, successful co-amorphous formulations of a basic drug with an acidic AA could only be prepared by SD. PMID- 30278257 TI - Enhanced dissolution of naproxen from pure-drug, crystalline nanoparticles: A case study formulated into spray-dried granules and compressed tablets. AB - This is a case study of the use of rapidly-dissolving naproxen crystalline nanoparticles to prepare compressed tablets. The dissolution rates of different formulations were determined: the crystalline pure-drug nanodispersion, a pure drug microsuspension, a granule prepared by spray drying the nanodispersion with mannitol, and a tablet prepared by compressing the granule with a bulking agent and a disintegrant. The goal was to determine the influence of each of the process steps on the rapid dissolution of the nanodispersion. A procedure was developed to allow sampling during the first 120 s of dissolution. Dissolution of the nanodispersion was completed after 60 s under both sink and non-sink conditions. Spray drying with mannitol delayed dissolution slightly under both sink and non-sink conditions. Under sink conditions a microsuspension (volume median size 11 um) showed similar rapid dissolution to the nanodispersion. We propose this to be a result of rapid shrinkage of the microparticles on dissolution under sink conditions. This nullifies any effects of specific surface on dissolution rate. Under non-sink conditions the microparticles retain their lower specific surface for a longer time during dissolution and dissolve therefore more slowly. When compressed into tablets, the dissolution rates of nanoparticles or microparticles were determined primarily by the tablet disintegration time; the influence of sink or non-sink conditions was only observable after disintegration. PMID- 30278258 TI - MiR-31 and miR-143 affect steroid hormone synthesis and inhibit cell apoptosis in bovine granulosa cells through FSHR. AB - The regulatory role of microRNAs (miRNAs) has been explored in ovarian cells, and the effects of miRNAs on gonadal development, apoptosis, ovulation, and steroid production have been reported. In this study, we analyzed the effects of follicle stimulating hormone (FSH) on miR-31 and miR-143 expression levels in bovine granulosa cells (GCs). Our results demonstrated that the FSH receptor (FSHR) is a common target gene of miR-31 and miR-143 in bovine GCs. We further analyzed the roles of miR-31 and miR-143 in bovine GCs by transfecting miR-31 and miR-143 mimics and inhibitors. The Western blot and RT-PCR results showed that miR-31 and miR-143 reduced the mRNA and protein expression levels of FSHR. Moreover, miR-31 overexpression decreased the secretion of progesterone (P4), and miR-143 overexpression decreased both the synthesis of P4 and the secretion of estrogen (E2). In contrast, miR-31 inhibition increased the secretion of progesterone (P4), and miR-143 inhibition increased both the synthesis of P4 and the secretion of E2. Finally, we analyzed the possible effects of miR-31 and miR-143 on bovine GC apoptosis. The results showed that transfection with miR-31 and miR-143 mimics promoted GC apoptosis and that miR-143 and miR-31 inhibition reduced the rate of apoptosis in bovine GCs. Taken together, our results indicate that miR-31 and miR 143 decrease steroid hormone synthesis and inhibit bovine GC apoptosis by targeting FSHR. PMID- 30278259 TI - Effect of equine chorionic gonadotropin administration on day 8 post-partum on ovarian follicular development, uterine health and uterine involution in lactating dairy cows. AB - The objective was to evaluate the effect of equine chorionic gonadotropin (eCG) injection on day 8 postpartum on ovarian cyclicity, uterine health and uterine involution in lactating dairy cows. Lactating dairy cows [n = 34, (21 primiparous and 13 multiparous)] were enrolled in the study. Animals were stratified by calving date, parity and BCS, and randomly assigned to either control (CON n = 18) or eCG treatments (n = 16). On day 8 +/- 0.9 post-partum (pp), eCG treatment cows received a 2 ml i.m. injection (500 IU) of eCG and control treatment cows received a 2 ml i.m. injection of 0.9% sodium chloride. Ovaries were examined by transrectal ultrasound every second day from day 10 pp until ovulation or regression of the first follicle wave, and the diameter of the dominant follicle was recorded at each exam. Ultrasound exams were conducted on days 21, 28, 35 and 42 pp to measure the diameter of the cervix and the uterine horns. Vaginal discharge score (VDS) was recorded on a 1 to 5 scale on days 14, 21, 28, 35 and 42 pp. Endometrial cytology samples were collected on day 42 pp, and the percentage of polymorphonuclear neutrophils (PMN) determined. Milk samples were collected three times per week from day 14 pp until day 60 pp for P4 determination. Ovarian follicular development variables, ovarian function variables analysed and incidence of subclinical endometritis were not affected by treatment. There was a treatment by parity interaction for pp interval to commencement of luteal activity (P = 0.04) and number of luteal phases (P = 0.05), whereby eCG treatment caused an earlier pp commencement of luteal activity and a greater number of luteal phases in multiparous cows, but not in primiparous cows. A significant effect of treatment on uterine involution was observed (previously gravid horn: P = 0.03; previously non-gravid horn: P = 0.01) and uterine health status (P = 0.03), whereby eCG cows had smaller mean horn uterine diameter and lesser VDS than CON cows. In summary, parenteral administration of 500 IU eCG on day 8 post-partum did not affect resumption of ovarian cyclicity in all cows but did enhance uterine involution and VDS. In multiparous cows, eCG advanced commencement of luteal activity and increased the number of luteal phases. PMID- 30278261 TI - Survival of Patients and Treatment-Related Outcome After Intra-Arterial Thrombolysis for Acute Lower Limb Ischemia. AB - BACKGROUND: The aim of this study is to evaluate the long-term survival and treatment-related outcome in patients treated with intra-arterial thrombolysis for acute lower limb ischemia. METHODS: The study was based on a prospective vascular database with retrospectively obtained supplementary information from the patients' files. Additionally, data on the patients' date and cause of death were obtained from Statistics Finland. A total of 155 patients with symptoms or signs of category I-IIa acute lower limb ischemia and angiographic evidence of native artery or bypass graft thromboembolic events were treated with intra arterial catheter-directed thrombolysis (CDT). Patients with severe ischemic stages at admission or those with contraindications for thrombolysis (n = 185) were treated with conventional surgical modalities and excluded from further analysis. RESULTS: The mean age of the patients at admission was 73 years (95% confidence interval 70.1-74.6). For descriptive purposes, age quartiles were used (<=64, 65-74, 75-82.5, >=83). The mean follow-up time was 126.3 months. The primary patency rates of native arteries/bypass grafts were 59.8%/31.7%, 35.4%/17.1%, and 18.7%/15.2% at 1, 5, and 10 years, respectively (P = 0.01). Correspondingly, the respective secondary patency rates were 65.2%/55.6%, 46.7%/39.8%, and 22.8%/30.5% (P = 0.88). A total of 190 additional procedures on 122 patients were required to preserve the patency after hospital discharge. At 1 year the cumulative survival was 78%, at 5 years 56%, and at 10 years 29%. The most common cause of death was cardiovascular (68.5%), predominantly presented by an acute coronary syndrome, while 9.6% died of cancer, 6.8% of pulmonary diseases, 8.2% of cerebrovascular causes, and 19.2% owing to trauma and other reasons. Atrial fibrillation (hazards ratio [HR] 2.31) and age over 83 years (HR 5.23 per age category) were significantly and independently associated with poorer cumulative post-procedural survival. Bypass graft thrombosis was associated with an increase in major amputations after CDT (HR 14.77). However, the presence of synthetic bypass grafts had a protective influence on limb salvage (HR 0.086). A total of 39 (25.2%) major amputations were performed during the follow-up period. Age over 75 years was the only significant and independent factor to negatively impact on amputation-free survival (HR 2.01), which was 24% at 10 years. CONCLUSIONS: The long-term patency after CDT is unfavorable, and additional procedures are needed to preserve adequate distal perfusion. Approximately 30% of the patients are alive at 10 years after the initial CDT. Increasing age and atrial fibrillation have a negative effect on the patients' survival. PMID- 30278260 TI - Impact of an Educational Intervention on Ankle-Brachial Index Performance Among Medical Students and Fidelity Assessment at Six Months. AB - BACKGROUND: The resting ankle-brachial index (ABI) is a clinical test to diagnose peripheral artery disease. The Wyatt's score has been proposed to assess the students' performance on ABI measurement on a healthy volunteer (HV). No study has shown that this score is sensitive to different teaching methods. In this randomized controlled trial, we wanted to determine whether didactic learning alone or didactic learning combined with experiential learning improves proficiency in the ABI procedure assessed by the Wyatt's score. METHODS: Medical students (n = 30) received a didactic learning, including (1) a presentation of the ABI guidelines and (2) a video demonstration. Each student was then randomized into 2 groups ("the no experiential learning group" and "the experiential learning group"). An initial evaluation was performed after the didactic learning and then the final evaluation at the end of the intervention. A student was considered to be proficient when he performed a correct ABI procedure on an HV. The correct procedure corresponds to the following: (1) correctly answered Wyatt's score and (2) a difference in the ABI measurement between a professor in vascular medicine and a student was <=0.15. RESULTS: No student was proficient at the initial evaluation. At the final evaluation, there was a significant difference between the number of proficient students for the Wyatt's score depending on their learning group [didactic alone (1/10) or didactic + experiential training (15/20)] and also for the ABI procedure [didactic alone (0/10) or didactic + experiential training (16/20)]. At 6 months, among the 12 students who passed the final evaluation, 4 students passed both the Wyatt's score and the ABI measurement. CONCLUSIONS: Our study demonstrates that the Wyatt's score was sensitive to an educational intervention and no improvement was found in the case of "no experiential learning." The Wyatt's score could be used to evaluate the student on ABI measurement after an educational intervention. TRIAL REGISTRATION: A randomized controlled trial was conducted in the Vascular Medicine Department of Rennes University Hospital (France). This was approved by the ethics review board of our institution (no. 16.150). PMID- 30278262 TI - Catheter-Directed Thrombolysis for Acute Limb Ischemia in an Asian Population. AB - BACKGROUND: The incidence of peripheral arterial occlusions in Asian populations is likely to increase exponentially in the present and future decades due to the adapted Western lifestyle in metropolitan Asian life, extended life expectancies, and high rates of smoking. The literature on thrombolytic treatment of peripheral arterial occlusions in Asian populations is limited. Therefore, we evaluated the thrombolysis results in a real-world contemporary Asian cohort of patients with peripheral arterial occlusions. METHODS: Retrospective review of all electronic patient records of patients who underwent thrombolytic therapy for peripheral arterial occlusions between July 2011 and July 2016 was conducted. Outcomes were angiographic patency, clinical success, bleeding complications, amputation rates, and mortality rates. RESULTS: In total, 82 patients (median age 66 years, range 34-95) underwent catheter-directed thrombolysis. Median treatment duration was 26 hr (3-209). Angiographic patency and clinical success rates were 64% and 66%, respectively. Bleeding complications occurred in 12% of patients of which 6% were major. Amputation-free rates were 81%, 67%, and 63% for 30 days, 6 months, and 1 year, respectively. In-hospital mortality was 6%. CONCLUSIONS: This study demonstrates that thrombolytic treatment of peripheral arterial occlusions in an Asian patient cohort yields comparable treatment success rates to Western cohorts; however, higher rates of bleeding complications are hazardous and remain a detrimental drawback of this treatment. PMID- 30278263 TI - Remote Ischemic Pre-conditioning in the Management of Intermittent Claudication: A Pilot Randomized Controlled Trial. AB - BACKGROUND: Animal data suggest that remote ischemic conditioning (RIC) can improve blood flow in ischemic limbs and, consequently, may benefit claudication patients. Supervised exercise is the preferred first-line intervention for patients with intermittent claudication (IC) but is constrained by limited availability and logistical issues, particularly in rural settings. The aim of this study is to evaluate remote ischemic pre-conditioning in the management of intermittent claudication patients. METHODS: We undertook a randomized clinical trial to evaluate RIC's effect in claudication patients. Stable IC patients were randomly allocated to receive RIC alone, structured exercise (SE) alone, RIC plus SE, or to a control group which received standard advice and risk factor modification. Patients received their intervention over a 28-day period. RIC patients attended an RIC clinic every 3-4 days to undergo 4 cycles of 5-min upper limb ischemia followed by 5-min reperfusion induced with a standard blood pressure cuff. RESULTS: Forty-five patients were randomized, of whom 40 completed the trial (10 patients per group). The RIC alone, SE alone, and RIC plus SE groups all demonstrated significant improvements in pain-free walking distance and ankle-brachial pressure indices at 30 days. There were no differences in the magnitude of improvements between the groups. CONCLUSIONS: Compared with standard care RIC is promising as a home-delivered intervention. It appears to be equivalent to SE in the treatment of IC, with no apparent additive benefit to combining the 2 interventions in this small size sample. Large-scale randomized controlled trial is needed for validation. PMID- 30278264 TI - The Relationship between the Concentration of Cathepsin A, D, and E and the Concentration of Copper and Zinc, and the Size of the Aneurysmal Enlargement in the Wall of the Abdominal Aortic Aneurysm. AB - BACKGROUND: Despite advances in diagnostics and treatment, aortic aneurysms are an important clinical problem, mainly due to the accompanying complications that may lead to direct loss of life, also the number of diagnosed and operated aneurysms is constantly increasing. The aim of this study is to determine the relationship between the concentration of lysosomal peptidases cathepsin A, D, and E in the wall of the abdominal aortic aneurysm and the concentration of copper and zinc, and the size of the aneurysm widening in the wall of the abdominal aortic aneurysm. METHODS: The study included 27 patients with abdominal aortic aneurysm from the Department of Vascular Surgery and Transplantation of the University Clinical Hospital in Bialystok. The research material was the wall of the abdominal aortic aneurysm collected intraoperatively. The control material consisted of fragments of the abdominal aorta obtained from organ donors for transplantation. The concentration of cathepsin A, D, and E was determined using enzyme-linked immunosorbent assays. Concentrations of copper and zinc were determined by flame atomic absorption spectrometry after prior mineralization of the samples. All patients were interviewed and asked about basic demographic data, comorbidities, and risk factors for cardiovascular disease to which they were exposed in the past. The statistical analysis was performed using Statistica 10 statistical package. Mann-Whitney U-tests were used and also Spearman's r correlation assuming a significance level of P < 0.05. RESULTS: The concentration of cathepsin A, D, and E was higher in the aortic wall altered by the aneurysm than in the wall of the control aorta (P < 0.05). The analysis of the data showed that there was a positive correlation between the concentration of cathepsin A and D and the width of the aneurysmal widening (r = 0.699 and 0.750, respectively). There was no correlation between cathepsin E concentration and aneurysm width. CONCLUSIONS: The higher contents of cathepsin A, D, and E in the wall of the aortic aneurysm than in the normal aortic wall, as well as a positive correlation between the concentration of cathepsin A and D and the width of the aneurysmal widening, allow to assume the participation of these enzymes in the pathogenesis of the aneurysm.

PMID- 30278267 TI - Bundled Payments for Surgical Care-More Questions Than Answers. AB - Bundled payment models assign financial responsibility for extended episodes of care up to 90 days after operation. The report by Koeckert et al, in this issue, describes 376 patients having either transcatheter aortic valve replacements or surgical aortic valve replacements. They investigated the impact of readmissions on the Bundled Payments for Care Improvement initiative (BPCI) payment for Medicare valve patients. The authors' hospital was designated as a BPCI institution that linked reimbursement to the different phases of care (in patient, outpatient follow-up, emergency visits, and other postacute care) up to 90 days after operation. They found that bundled costs were significantly increased above BPCI reimbursements in readmitted patients, especially transcatheter aortic valve replacements patients who were readmitted late up to 90 days after operation. This apparent disconnect between BPCI reimbursement and actual costs raises questions about BPCI reimbursement. PMID- 30278268 TI - Differential Effects of Normoxic and Hyperoxic Reperfusion on Global Myocardial Ischemia-Reperfusion Injury. AB - The objectives were to investigate if after hypoxia or ischemia, normoxic reperfusion is associated with less oxidant stress (OS), inflammation, and myocardial injury than hyperoxic reperfusion. In this study, cardiomyocytes (H9c2 cells) were cultured in hypoxia, followed by reoxygenation in normoxia or hyperoxia. Cardiomyocyte OS, inflammation, and apoptosis were measured. In parallel experiments, rabbits were cannulated for cardiopulmonary bypass (CPB). Following cardioplegic arrest and aortic cross-clamp removal, hearts were reperfused under normoxic or hyperoxic conditions. Left ventricular developed pressure and contractility (LV +dP/dt) were recorded, and blood samples and heart tissues were collected for measurement of OS, inflammation, and cardiac injury. Results showed that H9c2 cells exposed to hyperoxic reoxygenation showed significant increases in OS, inflammation, and apoptosis compared to normoxic reoxygenation. Following CPB and 2-hour hyperoxic reperfusion, LV +dP/dt and left ventricular developed pressure were significantly decreased compared with pre-CPB values (to 36 +/- 21%, P = 0.002; and 53 +/- 20%, P = 0.02, respectively), associated with significant increases in all plasma and tissue biomarkers for OS, inflammation, and myocardial injury. In contrast, LV +dP/dt was relatively well preserved under normoxic reperfusion conditions (to 70 +/- 14% after 2-hour reperfusion), and was associated with an attenuated myocardial OS, inflammatory, apoptotic, and injury response compared to the hyperoxia group (eg, cTn-I: 5.9 +/ 1.5 vs 20.2 +/- 7.6 ng/mL, respectively, P < 0.0001). Overall, in both in vitro and in vivo experiments, normoxic reperfusion/reoxygenation was associated with less robust OS, inflammation, apoptosis, and myocardial injury compared with hyperoxic reperfusion/reoxygenation. These results suggest that hyperoxia should be avoided to minimize myocardial OS, inflammation, and ventricular dysfunction after CPB. PMID- 30278269 TI - Simultaneous Systemic to Pulmonary Shunt and Pulmonary Artery Banding is a Viable Option for Neonatal Palliation of Single Ventricle Physiology. AB - BACKGROUND: A subset of neonates with single ventricle (SV) physiology has antegrade pulmonary blood flow that is deemed unlikely to be reliable until Glenn. We have used systemic to pulmonary shunt (SPS) with pulmonary artery banding (PAB) to optimize pulmonary blood flow while maintaining reserve antegrade flow. We hypothesize that this is an effective strategy that can be accomplished without the routine need for cardiopulmonary bypass (CPB). METHODS: We retrospectively reviewed the records of 60 neonates who underwent combined SPS+PAB between 2004-2015. Data is presented as median with quartiles. RESULTS: Children were 8 (4-19) days old at surgery and included 38 (63%) boys. Atresia or severe stenosis of the sub-pulmonary atrioventricular (AV) valve associated with pulmonary blood flow across a bulbo-ventricular foramen (BVF) was present in 37(62%). In 20 (33%), heterotaxy-associated unbalanced AV canal with pulmonary stenosis with or without anomalous pulmonary venous drainage was present. First stage palliation was accomplished without CPB in 44 patients (73%). There were seven (12%) hospital deaths, four amongst the 20 (20%) with heterotaxy. 53 children were followed for a median 5.1 (1.8 - 8.2) years. Three early re interventions were required after initial palliation (one PAB adjustment, two SPS balloon angioplasties). Five additional heterotaxy patients experienced late mortality during follow-up. There were no early or emergent Glenn. 39 patients have reached Fontan circulation with a median pre-Fontan PA pressure of 14 (12 18) mmHg. One patient converted to bi-ventricular physiology and the remaining await completion Fontan. Heterotaxy was the only independent predictor of mortality (hazard ratio 10 (2.3-44, p<0.001)). CONCLUSION: In SV patients with unreliable antegrade PA flow, SPS+PAB is an effective first stage palliation. SV patients with heterotaxy are at increased risk for mortality.

PMID- 30278272 TI - Pulmonary Vein Stenosis: Outcomes in Children with Congenital Heart Disease and Prematurity. AB - OBJECTIVES: Pulmonary vein stenosis (PVS) is a rare condition that has been linked to prematurity and congenital heart disease (CHD). Despite these associations, treatment options are limited and outcomes are guarded. We investigated differences in PVS outcomes based on the presence of CHD and prematurity, and risk factors for mortality or lung transplantation in PVS. METHODS: Single center retrospective cohort study of patients diagnosed with PVS between January 2005 and May 2016, identified by ICD codes with chart validation. Cox proportional hazard models assessed risk factors for the composite outcome of mortality or lung transplantation. RESULTS: Ninety-three patients with PVS were identified: 65 (70%) had significant CHD, 32 (34%) were premature, and 14 (15%) were premature with CHD. Sixty-five (70%) underwent a PVS intervention and 42 (46%) underwent >=2 interventions. Twenty-five (27%) subjects died or underwent lung transplant 5.8 months (Interquartile range (IQR) 1.1, 15.3) after diagnosis. There was no difference in age at diagnosis or mortality based on presence of CHD or prematurity. PVS diagnosis before age 6 months and greater than one pulmonary vein affected at diagnosis were associated with higher mortality (HR 3.4 (95% CI 1.5, 7.5), p=0.003, and HR 2.1 per additional vein affected (95% CI 1.3, 3.4), p=0.004, respectively). CONCLUSIONS: Survival in children with PVS is poor, independent of underlying CHD or prematurity. Younger age and greater number of veins affected at diagnosis are risk factors for worse outcome. Understanding causal mechanisms and development of treatment strategies are necessary to improve outcomes.

AB - Understanding the dynamics of veterinary antibiotic and related antibiotic resistance genes (ARGs) during swine manure composting is crucial in assessing the environmental risk of antibiotics, which could effectively reduce their impact in natural environments. This study investigated the dissipation of oxytetracycline (OTC), sulfamerazine (SM1) and ciprofloxacin (CIP) as well as the behaviour of their corresponding ARGs during swine manure composting. These antibiotics were added at two concentration levels and two different methods of addition (single/mixture). The results indicated that the removal efficiency of antibiotics by composting were >=85%, except for the single-SM1 treatment. The tetracycline resistance genes (TRGs) encoding ribosomal protection proteins (RPP) and efflux pump (EFP) and fluoroquinolone resistance genes (FRGs) could be effectively removed after 42 days. On the contrary, the TRGs encoding enzymatic inactivation (EI) and sulfonamide resistance genes (SRGs) were enriched up to 31 fold (sul 2 in single-low-SM1). Statistical analyses indicated that the behaviour of these class antibiotics and ARGs were controlled by microbial activity and significantly influenced by environmental factors (mainly C/N, moisture and pH) throughout the composting process.

AB - Rapeseed (RS) waste was used for sequential biosorption from aqueous solutions of two target micropollutants: lead ions and Reactive blue 19 (Rb19) dye, through an integrated approach, combining experimental assessment and statistical modeling. In both cases of sequential biosorption, a pseudo-second order kinetic model fitted the biosorption data well. Intraparticle diffusion proved to be the rate limiting step in the sequential retention of both micropollutants. A selective desorption of metal ions and anionic dye at pH 2.5 and 10.5, respectively was observed. The quadratic models generated by response surface methodology (RSM) adequately described the sequential biosorption process and the desorption process, respectively. XPS and FTIR analysis indicated the mechanisms involved in the retention of target pollutants.

AB - The study investigated the effects of three in situ methods for controlling nitrogen loss and maturity with different mechanisms: struvite-based addition (K2HPO4 and MgO, MP), woody peat addition (WP) and intermittent aeration (IA), during composting of vegetable waste (cucumber vine) with temperature over 70 degrees C to inactivate potential viral pathogens. The experiment was conducted in a 200 L pilot-scale composting system, with which temperature and ammonia emission were recorded in real time, and solid samples were collected and analyzed during the process. The results indicated that the methods of MP and IA reduced the total nitrogen loss by 27.5% and 16.1%, respectively, without inhibitory effects on the temperature, nutrient availability and maturity. The WP method significantly decreased the nitrogen loss but could not maintain the thermophilic stage over 70 degrees C, because of its influence on the material physio-chemical characteristics caused by woody peat addition. In conclusion, all three methods could promote the maturity process, and 20 days should be adequate for vegetable waste composting with a good nutrient availability. Considering the two factors of reducing nitrogen loss and achieving high temperatures together, we recommended the struvite-based controlling method with the mechanism of chemisorption to reduce nitrogen loss during vegetable waste composting that requires temperatures over 70 degrees C.

PMID- 30278277 TI - Exploring different photosensitizers to optimize elimination of planktonic and biofilm forms of Enterococcus faecalis from infected root canal during antimicrobial photodynamic therapy. AB - BACKGROUND: Despite the high success rate of endodontic treatment, failure may occur in some cases. In this case, Enterococcus faecalis is the most common species in endodontic treatment failure and post-treatment apical periodontitis. Therefore, a new adjunctive strategy is needed for the prevention of endodontic infections due to E. faecalis. The aim of the present study was to compare the antimicrobial and anti-biofilm activities of different common photosensitizers (PSs) for use in antimicrobial photodynamic therapy (aPDT) against E. faecalis. MATERIALS AND METHODS: E. faecalis strain ATCC 29212 was used as the tested strain and methylene blue (MB), toluidine blue O (TBO), indocyanine green (ICG), and curcumin (CUR) were used as PSs. Irradiation was carried out using diode laser and light emitting diode (LED) at wavelengths related to the above PSs. Then, antimicrobial and anti-biofilm activities were measured using the microbial viability assay and crystal violet test, respectively. RESULTS: aPDT with using the above PSs significantly decreased the CFU/mL count of E. faecalis compared to the control group (P < 0.05). The killing percentage of E. faecalis via PS mediated aPDT was 99.6%, 98.2%, 85.1%, and 65.0% for CUR, ICG, TBO, and MB, respectively. aPDT using the above PSs significantly decreased the biofilm formation ability of E. faecalis compared to the control group (P < 0.05). The biofilm reduction percentage of the PSs was 68.4%, 62.9%, 59.0%, and 47.6% for CUR, ICG, TBO, and MB, respectively. CONCLUSION: CUR and ICG mediated aPDT exhibited considerably more antimicrobial activity than other PSs, while TBO and MB demonstrated weaker anti-biofilm effects against E. faecalis compared to other PSs. PMID- 30278278 TI - Potassium iodide potentiated photodynamic inactivation of Enterococcus faecalis using Toluidine Blue: Comparative analysis and post-treatment biofilm formation study. AB - BACKGROUND: Photodynamic Inactivation (PDI) has recently gained interest as an alternative modality to fight pathogenic entities and its effect can be further enhanced by using certain inorganic salts. Here, the Potassium Iodide (KI) mediated PDI effect on Enterococcus faecalis using Toluidine Blue Ortho (TBO) as photosensitizer (PS) has been evaluated, and subsequent Biofilm formation extent is accounted for. METHODS: The comparative photoinactivation of TBO and TBO/KI on E.faecalis was investigated by quantifying surviving bacterial colonies after laser irradiation with 30,60, and 180 s exposure times and different PS/Potentiator concentrations. The biofilm formation capability of E.faecalis was observed by calculating Optical Density (OD595) of samples 24,48, and 72 h post PDI treatment. Scanning Electron Microscopy (SEM) was used as a qualitative measure of bacterial biofilm growth. RESULTS: More than 4 LOGS of photokilling was obtained for experimental groups with the highest PS/KI concentrations at 180 s exposure time. All KI-potentiated groups showed enhancement in PDI effect when compared to non-potentiated counterparts. The degree of recurring biofilm for laser-treated groups also showed to be much less than that of control group, as confirmed by both OD595 measurement and SEM imaging. PMID- 30278279 TI - Porphyrins containing basic aliphatic amino groups as potential broad-spectrum antimicrobial agents. AB - New porphyrin derivatives bearing basic aliphatic amino groups were synthesized from the condensation of meso-4-[(3-N,N dimethylaminopropoxy)phenyl]dipyrromethane, pentafluorobenzaldehyde and 4-(3-N,N dimethylaminopropoxy)benzaldehyde. The reaction was catalyzed by trifluoroacetic acid in acetonitrile. This approach was used to obtain porphyrins with different patterns of substitution, of which three of them were isolated: 5,15-di(4 pentafluorophenyl)-10,20-di[4-(3-N,N-dimethylaminopropoxy)phenyl]porphyrin (F10APP), 5-(4-pentafluorophenyl)-10,15,20-tris[4-(3-N,N dimethylaminopropoxy)phenyl]porphyrin (F5APP) and 5,10,15,20-tetrakis[4-(3-N,N dimethylaminopropoxy)phenyl]porphyrin (TAPP). The UV-vis spectroscopic characterizations and the photodynamic effect of these compounds were compared in N,N-dimethylformamide. These porphyrins showed red fluorescence emission with quantum yields of 0.09-0.15. Moreover, they sensitized the production of singlet molecular oxygen, reaching quantum yields values of 0.33-0.53. Photodynamic inactivation was studied in two bacteria, Staphylococcus aureus and Escherichia coli, and a yeast Candida albicans. High amount of cell-bound porphyrin was obtained at short times (<2 min) of incubation. After 15 min irradiation, a 7 log reduction of S. aureus was found for cells treated with 1 MUM F5APP. Similar photokilling was obtained in E. coli, but using 7.5 MUM F5APP and 30 min irradiation. Under these conditions, a decrease of 5 log was observed in C. albicans cells. An increase in cell survival was observed by addition of sodium azide, whereas a slight protective effect was found in the presence of D mannitol. Moreover, the photoinactivation mediated by these porphyrins was higher in D2O than in water. Thus, these porphyrins induced the photodynamic activity mainly through the intermediacy of O2(1Deltag). In particular, F5APP was a highly effective photosensitizer with application as a broad-spectrum antimicrobial. This porphyrin contains three basic aliphatic amino groups that may be protonated at physiological pH. In addition, it is substituted by a lipophilic pentafluorophenyl group, which confers an amphiphilic character to the tetrapyrrolic macrocycle. This effect can increase the interaction with the cell envelopment, improving the photocytotoxic activity against the microorganisms. PMID- 30278280 TI - Low-cost light-induced therapy to treat rickettsial infection. AB - Antimicrobial photodynamic therapy uses a nontoxic photosensitizer with the assistance of harmless visible light to activate the photosensitizer. Consequently, the excited state of the photosensitizer interacts with molecular oxygen to produce reactive oxygen species, which have the antimicrobial effect. In this study, we evaluated the effect of photodynamic therapy on Vero cells infected with rickettsia using methylene blue as a photosensitizer along with red light. A significant reduction (by 96%) in the number of viable Rickettsia slovaca was determined by quantitative RT-PCR 48 h after the treatment with methylene blue followed by 30 min of red light excitation. A statistically significant reduction of R. slovaca was also recorded with pretreatment (by 99%). To the best of our knowledge, this result is the first one in the literature to confirm the effectiveness of photodynamic therapy for the elimination of R. slovaca and to suggest this technique as a good supportive treatment for rickettsial infections.

AB - Reported herein is the design, synthesis, and pharmacologic evaluation of a class of TRPV1 antagonists constructed on a N1-(isoquinolin-5-yl)-N2-phenylpyrrolidine 1,2-dicarboxamide platform that evolved from a 5-aminoisoquinoline urea lead. Advancing the SAR of this series led to the eventual identification of 3b, comprising a p-Br substituted phenyl. In a TRPV1 functional assay, using cells expressing recombinant human TRPV1 channels, 3b displayed potent antagonism activated by capsaicin (IC50 = 0.084 MUM) and protons (IC50 = 0.313 MUM). In the preliminary analgesic and body temperature tests, 3b exhibited good efficacy in capsaicin-induced and heat-induced pain models and without hyperthermia side effect. On the basis of its superior profiles, 3b could be considered as the lead candidate for the further development of antinociceptive drugs. PMID- 30278282 TI - Design, synthesis, modeling studies and biological evaluation of thiazolidine derivatives containing pyrazole core as potential anti-diabetic PPAR-gamma agonists and anti-inflammatory COX-2 selective inhibitors. AB - Nowadays, diabetes and its associated inflammatory complications are important public health problems worldwide. Market limitations of drugs with dual actions as anti-inflammatory (AI) and anti-diabetic have been led to a temptation for focusing on the discovery and development of new compounds with potential AI and anti-diabetic activities. Herein, we synthesized two new series containing pyrazole ring with vicinal diaryl rings as selective COX-2 moiety and thiazolidindione (series 12a-f) or thiazolidinone (series 13a-f) as anti-diabetic moiety and the two moieties were linked together with methylene or methylenehydrazone functionality. The two series were evaluated for their COX inhibition, AI activity and ulcerogenic liability and for the anti-diabetic activity; 12a-f and 13a-f were assessed in vitro against alpha-glucosidase, beta- glucosidase, in vivo hypoglycemic activity (one day and 15 days studies) in addition to PPARgamma activation study. Four compounds (12c, 12f, 13b and 13f) had higher COX-2 S.I. (8.69-9.26) than the COX-2 selective drug celecoxib (COX-2 S.I. = 8.60) and showed the highest AI activities and the lowest ulcerogenicity than other derivatives. Also, two thiazolidindione derivatives 12e and 12f and two thiazolidinone derivatives 13b and 13c showed higher inhibitory activities against alpha- and beta-glucosidase (% inhibitory activity = 62.15, 55.30, 65.37, 59.08 for alpha-glucosidase and 57.42, 60.07, 58.19, 66.90 for beta-glucosidase respectively) than reference compounds (acarbose with % inhibitory activity = 49.50 for alpha-glucosidase and d-saccharic acid 1,4-lactone monohydrate with % inhibitory activity = 53.42 for beta-glucosidase) and also showed good PPAR-gamma activation and good hypoglycemic effect in comparison to pioglitazone and rosiglitazone. Moreover, Shape comparison and docking studies were carried out to understand their interaction and similarity with standard drugs. PMID- 30278283 TI - RUNX1-EVI1 induces dysplastic hematopoiesis and acute leukemia of the megakaryocytic lineage in mice. AB - The RUNX1-EVI1 gene generated by the t(3;21) translocation encodes a chimeric transcription factor and is a causative gene in the development of de novo acute megakaryoblastic leukemia and leukemic transformation of hematopoietic stem cell tumors. Heterozygous RUNX1-EVI1 knock-in mice die in utero due to hemorrhage in the central nervous system and spinal cord and complete abolishment of definitive hematopoiesis in the fetal liver. On the other hand, the chimeric knock-in mouse develops acute megakaryoblastic leukemia. We created another mouse model of RUNX1 EVI1 using transplantation of retrovirus-infected bone marrow cells. Some mice transplanted with RUNX1-EVI1-expressing bone marrow cells developed acute megakaryoblastic leukemia within eight months, and the other non-leukemic mice showed thrombocytosis at around a year. In the non-leukemic mice, dysplastic megakaryocytes proliferated in the bone marrow and frequently infiltrated into the spleen, which was not associated with marrow fibrosis. In the leukemic mice, their tumor cells were positive for c-kit and CD41, and negative for TER119. Although they were negative for platelet peroxidase in the electron microscopic analysis, they had multiple centrioles in the cytoplasm, which are characteristic of megakaryocytes that undergo endomitosis. The leukemic cells were serially transplantable, and gene-expression analyses using quantitative RT-PCR arrays revealed that they showed significantly elevated expression of stem cell, primitive hematopoietic cell and endothelial cell-related genes compared with normal bone marrow cells. All these data suggested that RUNX1-EVI1 caused dysplastic hematopoiesis or leukemia of the megakaryocytic lineage and endowed gene expression profiles distinctive of immature hematopoietic cells. PMID- 30278286 TI - Potential in vitro and ex vivo targeting of bZIP53 involved in stress response and seed maturation in Arabidopsis thaliana by five designed peptide inhibitors. AB - Basic leucine zipper (bZIP) transcription factors (TFs) are eukaryote-specific proteins that bind to DNA as a homodimer or heterodimer and regulate gene expression. They are involved in several biological processes in plants; therefore inhibiting bZIP-DNA binding activity by targeting protein-protein interface is an attractive proposition with aspects of both basic and applied biology. Here, we describe the equilibrium and kinetic interactions studies of a designed peptide inhibitor A-ZIP53 and its four variants with the bZIP53 protein, a key regulator of seed maturation phase and stress response in Arabidopsis. Five designed peptide inhibitors were primed to preferentially interact with bZIP53 and inhibit its DNA binding activity. Isothermal circular dichroism (CD) studies were used to quantify the structural changes accompanying heterodimers formation between bZIP53 and five A-ZIP53s. Equilibrium studies using electrophoretic mobility shift assay (EMSA) and fluorescence polarization (FP) assays suggest that A-ZIP53s and bZIP53 mixture form heterodimers, incapable of binding to DNA. Four A-ZIP53 derivatives were designed with additional interactions that drive heterodimerization with bZIP53. A-ZIP53s dose-dependent FP studies show that peptide inhibitors displaced the DNA bound bZIP53 with nM half-maximal inhibitory (IC50) concentrations. Using FP, time-dependent displacement kinetic studies were used to rank five A-ZIP53s for their abilities to displace DNA-bound bZIP53 with a rank order of A-ZIP53 < A-ZIP53(A -> E) < A-ZIP53(N -> A) < A-ZIP53(R -> E) < A ZIP53(A -> E,N -> A). In transient transfection assays, bZIP53-mediated GUS activity was inhibited by equimolar concentrations of five A-ZIP53s with A ZIP53(A -> E,N -> A) the most effective one. Similar peptide inhibitors may be designed against other bZIP proteins to study their functions in vivo. PMID- 30278285 TI - Effectiveness of a school-based intervention to prevent child sexual abuse Evaluation of the German IGEL program. AB - BACKGROUND: Child sexual abuse (CSA) is a problem with severe consequences for victimized children. A variety of interventions have been developed and implemented over the last decades to prevent CSA. However, most of them have not been systematically evaluated to determine their effectiveness. The IGEL program is a school-based intervention to prevent CSA in third-grade primary school children in Germany. METHODS: This study was conducted using a quasi-experimental design, in which almost 300 children and their parents from eight intervention and four control schools were surveyed three times (pretest, posttest, 3 months later). In order to measure outcomes, a questionnaire was developed based on validated instruments to assess the knowledge, courses of action and self protective skills of the children. Furthermore, increased anxiety and generalized touch aversion were examined as potentially harmful side effects of the program. RESULTS: The results clearly demonstrate increased CSA-related knowledge and courses of action in children from the intervention group compared to the control children. These effects were medium-sized and sustained for at least three months after the last session. No meaningful negative side effects were detected in the evaluation for either the children or parents. CONCLUSION: The outcome evaluation indicates that the IGEL program is an effective intervention in terms of knowledge about CSA and known courses of action, and may therefore contribute to the prevention of CSA in primary schools. Despite this positive core finding of the intermediate outcomes, some adaptations of the program to children with different cultural backgrounds were made prior to further dissemination. PMID- 30278287 TI - Predicting the location of the non-local contacts in alpha-synuclein. AB - In this paper, the Sequential Collapse Model (SCM) for protein folding pathways is applied to investigate the location of the non-local contacts in the intrinsically disordered state of alpha-synuclein, a protein implicated in the onset and spreading of several serious neurodegenerative diseases. The model relies on the entropic cost of forming protein loops due to self-crowding effects, and the protein sequence to determine contact location and stability. It is found that the model predicts the existence of several possible non-local contacts, and the location of the non-local contacts is consistent with existing experimental evidence. The bearing of these findings on the pathogenic mechanism and its regulation is discussed. PMID- 30278284 TI - Mechanisms of persistence by small DNA tumor viruses. AB - Virus infection contributes to nearly 15% of human cancers worldwide. Many of the oncogenic viruses tend to cause cancer in immunosuppressed individuals, but maintain asymptomatic, persistent infection for decades in the general population. In this review, we discuss the tactics employed by two small DNA tumor viruses, Human papillomavirus (HPV) and Merkel cell polyomavirus (MCPyV), to establish persistent infection. We will also highlight recent key findings as well as outstanding questions regarding the mechanisms by which HPV and MCPyV evade host immune control to promote their survival. Since persistent infection enables virus-induced tumorigenesis, identifying the mechanisms by which small DNA tumor viruses achieve latent infection may inform new approaches for preventing and treating their respective human cancers. PMID- 30278289 TI - From pattern to process: studies at the interface of gene regulatory networks, morphogenesis, and evolution. AB - The development of anatomical structures is complex, beginning with patterning of gene expression by multiple gene regulatory networks (GRNs). These networks ultimately regulate the activity of effector molecules, which in turn alter cellular behavior during development. Together these processes biomechanically produce the three-dimensional shape that the anatomical structure adopts over time. However, the interfaces between these processes are often overlooked and also include counter-intuitive feedback mechanisms. In this review, we examine each step in this extraordinarily complex process and explore how evolutionary developmental biology model systems, such as butterfly scales, vertebrate teeth, and the Drosophila dorsal appendage offer a complementary approach to expose the multifactorial integration of genetics and morphogenesis from an alternative perspective. PMID- 30278288 TI - Structural characterization of 1-deoxy-D-xylulose 5-phosphate Reductoisomerase from Vibrio vulnificus. AB - Vibrio vulnificus, a gram-negative bacterium, is the leading cause of seafood borne illnesses and mortality in the United States. Previous studies have identified metabolites 2-C-methylerythritol 4-phosphate (MEP) as being essential for V. vulnificus growth and function. It was shown that 1-deoxy-D-xylulose-5 phosphate reductoisomerase (Dxr) is a critical enzyme in the viability of V. vulnificus, and many other bacteria, as it catalyzes the rearrangement of 1-deoxy D-xylulose-5-phosphate (Dxp) to 2-C-methylerythritol 4-phosphate (MEP) within the MEP pathway, found in plants and bacteria. The MEP pathway produces the isoprenoids, isopentenyl diphosphate and dimethylallyl pyrophosphate. In this study, we produced and structurally characterized V. vulnificus Dxr. The enzyme forms a dimeric assembly and contains a metal ion in the active site. Protein produced in Escherichia coli co-purifies with Mg2+ ions, however the Mg2+ cations may be substituted with Mn2+, as both of these metals may be utilized by Dxrs. These findings will provide a basis for the design of Dxr inhibitors that may find application as antimicrobial compounds. PMID- 30278290 TI - A Practical Cadaveric Model for Intracranial Bypass Training. AB - BACKGROUND: Intracranial bypass is technically challenging and difficult to learn owing to its relative rarity and complexity. Although multiple training models for intracranial bypass exist, a detailed depiction of the use and fidelity of cadaveric specimens for bypass training is lacking in the literature. This study describes use of preserved cadaveric specimens as a practical training model for performance of multiple intracranial bypasses and discusses the surgical setup for a cadaveric bypass laboratory. METHODS: Using a cadaveric specimen and basic microneurosurgical instruments and supplies, 5 intracranial bypasses were performed (superficial temporal artery [STA]-to-middle cerebral artery [MCA], MCA to-MCA, STA-to-posterior cerebral artery [PCA], anterior cerebral artery-to anterior cerebral artery, and posterior inferior cerebellar artery-to-posterior inferior cerebellar artery) using pterional, subtemporal, interhemispheric, and suboccipital approach. Bypass integrity was assessed by direct fluid injection into the adjacent vessel segment. All procedures were recorded. RESULTS: Procedural steps mirrored actual bypass surgery and included vessel marking, performance of arteriotomy, and completion of an end-to-end, end-to-side, or side to-side anastomosis. Simulations included anatomically appropriate exposures of common intracranial (MCA, PCA, posterior inferior cerebellar artery, anterior cerebral artery) and extracranial (STA) vessels encountered during cerebral bypass surgery and high-fidelity recreations of the operative corridors associated with deeper anastomoses, such as STA-to-PCA bypass. Vessel diameters were 1.5-2.1 mm, and anastomosis times were 20-40 minutes. Immediate feedback on anastomotic integrity was achieved via direct fluid injection adjacent to the anastomosis site. CONCLUSIONS: The cadaveric specimen trainee model is a relatively simple yet high-fidelity approach for learning intracranial bypass. PMID- 30278291 TI - Risk factors of intra-procedural rupture in the endovascular treatment of unruptured intracranial aneurysms: a single center experience with 1232 procedures. AB - BACKGROUND: and purpose: Intra-procedural rupture (IPR) is a rare complication during endovascular treatment (EVT) of unruptured intracranial aneurysms (UIAs), however, universally leads to poor outcomes if not properly managed. In this study, we intend to illuminate the risk factors of IPR during EVT of UIAs. METHODS: Patients with UIAs treated with EVT in our center from January 2010 to March 2017 were retrospectively collected and reviewed. Univariate analysis and multivariate logistic analysis were performed to analyze the risk factors of IPR. RESULTS: A total of 1232 patients with 1312 unruptured aneurysms were included in the study. IPR occurred in 11 patients (0.9%). Univariate analysis showed that cardiac comorbidities, irregular morphology and location on anterior communicating artery were significantly associated with IPR (P<0.05). In addition, stent placement was related to lower risk of IPR compared with non stent placement (P=0.024). The multivariate analysis showed that cardiac comorbidities (P=0.016, OR=6.320), irregular morphology (P=0.001, OR=9.562) and location on AcomA (anterior communicating artery) (P=0.006, OR=6.971) were independent risk factors of IPR. CONCLUSION: The occurrence rate of intra procedural rupture was relatively low. Cardiac comorbidities, irregular morphology and location on AcomA are independent risk factors of intra-procedural rupture. Stents and flow diverters are safe and feasible in treating UIA, with significantly low risk of intra-procedural rupture. PMID- 30278292 TI - Degenerative Lumbar Spondylolisthesis: Biochemical Aspects and Evaluation of Stabilization Surgery Extent in Terms of Adjacent Segment Disease Theory. AB - OBJECTIVE: In lumbar degenerative spondylolisthesis (DSL), the criteria and extent of surgical treatment have not been strictly defined owing to the adjacent segment disease theory and unclear molecular pathogenesis. The present study analyzed the clinical and radiographic findings of patients after lower lumbar fusion surgery with single and 2-level DSL and explored the inflammatory mediator's role in DSL evolution and symptoms. METHODS: The prospective follow-up of patients with DSL, stratified by the stabilization extent (L4-L5, L5-S1, and L4-S1), included the Back Illness Pain and Disability 9-item questionnaire and native and dynamic radiographs to evaluate the intervertebral disc height and adjacent segments' angular motion. Follow-up examinations were performed at 3, 12, and 24 months. The pathological cytokine concentrations in the intervertebral disc and facet joints of the subchondral bone were assessed using the BioPlex assay in perioperatively collected patient samples and compared with those of control subjects obtained during multiorgan procurement. These findings were correlated with pain localization and severity. RESULTS: Statistical analysis of the questionnaire data revealed significant postoperative improvement in all patients, in particular, the L4-L5 group. Also, we found radiographic evidence of angular motion reduction in both adjacent segments near the limits of statistical significance and a meaningful correlation with subjective status improvement at 24 months. BioPlex analysis revealed platelet-derived growth factor 2 B subunits, interleukin-6, interleukin-8, and tumor necrosis factor-alpha were elevated in spinal unit segments and the interleukin-1beta levels correlated significantly with the intensity of low backache. CONCLUSIONS: Our findings did not support the adjacent segment disease theory. However, later development of these changes could not be excluded. The cytokines, chemokines, and growth factors play a significant role in DSL pathogenesis and symptoms.

PMID- 30278294 TI - Tolerability of adjunctive eslicarbazepine acetate according to concomitant lamotrigine or carbamazepine use: A subgroup analysis of three phase III trials in adults with focal (partial-onset) seizures. AB - OBJECTIVE: To evaluate and compare the effects of concomitant lamotrigine (LTG) or carbamazepine (CBZ) on the incidence of treatment-emergent adverse events (TEAEs) in patients taking adjunctive eslicarbazepine acetate (ESL) for focal (partial-onset) seizures (FS). METHODS: These post-hoc analyses of data pooled from three randomized, double-blind, placebo-controlled studies of adjunctive ESL (BIA-2093-301, -302 and -304) included adults (>=16 years) with FS refractory to 1-3 antiepileptic drugs (AEDs). Patients were randomized equally to placebo, ESL 400 mg (Studies 301 and 302 only), 800 mg, or 1200 mg once daily (8-week baseline, 2-week titration, and 12-week maintenance periods). TEAEs, TEAEs leading to discontinuation, and serious AEs (SAEs) were evaluated in patients taking, or not taking, LTG (excluding those taking CBZ or phenytoin [PHT]; i.e., the +LTG and -LTG/-CBZ subgroups), or CBZ (excluding those taking LTG or PHT; i.e., the +CBZ and -LTG/-CBZ subgroups) at baseline. RESULTS: LTG was used concomitantly by 248 patients (+LTG; placebo, n = 81; ESL, n = 167) and CBZ by 613 patients (+CBZ; placebo, n = 172; ESL, n = 441); 361 patients were taking neither LTG nor CBZ (-LTG/-CBZ; placebo, n = 109; ESL, n = 252). The overall incidence of TEAEs with ESL (any dose) was numerically higher for +CBZ (77%) than for +LTG (73%) or -LTG/-CBZ (68%; statistical significance not tested). Among patients taking ESL, dizziness, diplopia, and vomiting were reported more frequently in the +CBZ subgroup (30%, 14%, and 10%, respectively) than in the +LTG (16%, 8%, 5%) or -LTG/-CBZ (11%, 3%, 5%) subgroups. The overall incidence of TEAEs leading to discontinuation with ESL was higher for +CBZ (21%) than for +LTG (13%) or -LTG/-CBZ (15%). Dizziness leading to discontinuation with ESL was reported more frequently in the +CBZ subgroup than in the +LTG or -LTG/-CBZ subgroups (9%, 3%, and 3%, respectively). The overall incidence of SAEs in patients taking ESL was comparable across subgroups (+LTG, 5%; +CBZ, 6%; -LTG/ CBZ, 5%). The results were similar when evaluating placebo-adjusted incidences. CONCLUSION: There was a potential pharmacodynamic interaction between AEDs with a putatively similar mechanism of action, with a seemingly lesser interaction between ESL and LTG versus ESL and CBZ. If combining ESL with LTG or CBZ, clinicians should be aware of the potential risk for an increased incidence of TEAEs typically associated with voltage-gated sodium channel inhibitors (e.g., dizziness, blurred vision, vertigo, diplopia, headache, or vomiting).

AB - BACKGROUND: Previous studies have investigated the association between sleep duration, insomnia, day-time napping and metabolic syndrome individually, but never conjointly. In addition, the association with sleep medication use has yet to be investigated. We aimed to examine the associations between these sleep related characteristics and the metabolic syndrome, individually and conjointly, in a population-based cohort. MATERIAL AND METHODS: We used cross-sectional data of 1679 participants from the New Hoorn study, 52.6% women and age 60.8 + 6.4y. Sleep duration, insomnia, and day-time napping were measured using validated questionnaires. The use of sleep medication was documented by the registration of dispensing labels. The metabolic syndrome was defined according to ATP III. Linear and Poisson regressions were used, and all analyses were adjusted for age, sex, education level, job status, smoking, physical activity, depression and BMI. RESULTS: In our population-based cohort, 447 (26.6%) persons had the metabolic syndrome. Individual associations showed that, after correction, day-time napping for <=30 min and >30 min was associated with a prevalence ratio for the metabolic syndrome of 1.28 (95% CI: 1.1-1.5) and 1.74 (95% CI: 1.4-2.2), respectively, compared to participants who did not nap. Sleep duration, insomnia, and sleep medication use were not associated with the metabolic syndrome individually. However, conjointly analyses showed that, after correction, having >=2 sleep related characteristics was associated with a PR of 1.36 (95% CI: 1.0-1.8) of having the metabolic syndrome, compared to having no sleep-related characteristics. CONCLUSION: Sleep-related characteristics were associated with a higher prevalence of the metabolic syndrome in the general population.

AB - OBJECTIVE: The venous outlet of anterior condylar arteriovenous fistulas (AC AVFs) often empties into the anterior condylar vein (ACV). Hypoglossal nerve palsy is one of the major complications after transvenous embolization (TVE) for the AC-AVF within the hypoglossal canal. However, no studies have investigated the route of the hypoglossal nerve within the hypoglossal canal in AC-AVF. The aim of the current study is to retrospectively verify the anatomical route of the hypoglossal nerve within its canal using dynamic computed tomography angiography (CTA) in order to facilitate the safe TVE for AC-AVF. PATIENTS AND METHODS: We included five patients with AC-AVF from 2011 to 2017. Dynamic CTA was performed on all patients. When the ACV was well-visualized by dynamic CTA, the hypoglossal nerve could be recognized as a less-intense structure within the surrounding enhanced vasculatures and the nerve route within the canal was analyzed. We also analyzed the location of the fistulas by digital subtraction angiography and cone beam computed tomography. RESULTS: In all five patients, the filling defect of the hypoglossal nerve ran through the most caudal portion of the hypoglossal canal. The fistulous pouches were located in the hypoglossal canal in three cases, and in the jugular tubercle venous complex in two cases. In all three cases with AC-AVF in the hypoglossal canal, the fistulous pouches were located in the superior wall of the hypoglossal canal, which means superior to the ACV. We performed TVE in four patients and none developed post-therapeutic hypoglossal nerve palsy. CONCLUSION: In the current study, dynamic CTA is useful for detecting the hypoglossal nerve within the hypoglossal canal. The hypoglossal nerve usually ran the bottom of its canal and the fistulous pouches were usually located at the superior aspect of the canal opposite side to the hypoglossal nerve. Accordingly, the selective embolization within the fistulous pouch located in the superior aspect of the ACV including jugular tubercle venous complex can reduce the risk of hypoglossal nerve palsy. PMID- 30278297 TI - Severity of intracranial carotid artery calcification in intracranial atherosclerosis-related occlusion treated with endovascular thrombectomy. AB - OBJECTIVES: Intracranial atherosclerosis related large vessel occlusions (ICAS-O) are challenging to diagnose and manage. The degree of intracranial carotid artery calcification may assist pre-thrombectomy diagnosis of ICAS and guide treatment strategy. The aim of the study is to determine if intracranial carotid calcification is associated with ICAS-O. PATIENTS AND METHODS: Consecutive large vessel occlusion patients who underwent thrombectomy from 2006 to 2017 were retrospectively studied. Patients were classified into ICAS-O if pre-existing atherosclerotic lesion was identified as the etiology for large vessel occlusion during the thrombectomy. The degree of intracranial carotid artery calcification (ICAC), technical and clinical outcomes of ICAS-O was compared with non-ICAS-O patients. RESULTS: In a retrospective cohort study of 64 thrombectomy patients, ICAS-O accounted for 14.1% of cases and was associated with higher degree of carotid calcification (mean Woodcock scale 2.8 vs 1.6, p = 0.044), need of stent retreiver rescue (55.6% vs 5.5%, p = 0.001), and adjuvant stenting or angioplasty (33.3% vs 0%, p = 0.002) compared with non-ICAS-O. CONCLUSION: The severity of ICAC may be associated with ICAS-O as the underlying etiology amongst thrombectomy patients. Compared with large vessel occlusion of other causes, ICAS O was associated with more failure of aspiration and a higher need of adjuvant stenting and angioplasty.

PMID- 30278299 TI - Relevance of KFLC quantification to differentiate clinically isolated syndrome from multiple sclerosis at clinical onset. AB - OBJECTIVE: The objective of the research was to evaluate diagnostic and predictive value for determination of KFLC in cerebrospinal fluid (CSF) compared to the qualitative procedure of OCB determination in patients with CIS who converted to MS during a two-year period. PATIENTS AND METHODS: KFLC, total immunoglobulin G (IgG), serum albumin and CSF albumin were determined with an immunonephelometric method in 151 patients with suspected MS who were admitted to the Neurology Clinic while CSF/serum quotients (QKFLC, QIgG and QAlb) and indexes were calculated with regards to albumin (QCSF/Qserum). Presence of OCBs was determined by isoelectric focusing with immunofixation. Based on their clinical, OCB and magnetic resonance imaging (MRI) findings, 50 patients were classified as other neurological disorder patients (OND), and 101 patients were classified as CIS, 50 of which converted to MS during the two-year period. ROC analysis, ROC curve comparisons and comparison of median KFLC parameters were used to find optimal cut-off with regards to CIS diagnosis and conversion to MS. RESULTS: CSF KFLC median was 2,01 mg/L in MS group contrary to 0,68 mg/L and 0,17 mg/L in CIS and OND group, and KFLC index was 33,52 mg/L contrary to 9,68 mg/L and 3,71 mg/L (p < 0,0001). ROC analysis for accuracy of detection of intrathecal synthesis for QKFLC and KFLC index showed an AUC of 0,891 and 0,839 and the cut-off of 0,027 and 8,82, respectively (sensitivity 73,2% and 71,3%; specificity 96,0% and 98,0%; +PV 97,4% and 98,6%). The diagnostic accuracy of KFLC index for conversion from CIS to MS showed AUC of 0,840 and a cut-off of 9,092 (sensitivity 90,0%; specificity 73,3%; -PV 93,7%). Life age correlates significantly with serum KFLC (r = 0,34; p < 0,0001) and through aging process lower KFLC indexes can be expected, i.e. likelihood of false negative diagnoses. CONCLUSION: KFLC index showed diagnostic value, although it is not more specific and more sensitive than OCB. Application of KFLC might serve as a screening method while OCB could be used in uninterpretted cases only. Patients who converted to MS have significantly higher KFLC which can contribute to an early diagnosis and prompt therapy with its predictive role. PMID- 30278300 TI - Silver-Catalyzed Regio- and Stereoselective Formal Carbene Insertion into Unstrained C-C sigma-Bonds of 1,3-Dicarbonyls. AB - A regio- and stereoselective silver-catalyzed formal carbene insertion into 1,3 dicarbonyls has been developed, using N-nosylhydrazones as diazo surrogates. Two new C-C bonds are constructed at the carbenic carbon center through the selective cleavage of the C-C(=O) sigma-bond of acyclic 1,3-dicarbonyls, enabling the preparation of various synthetically useful polysubstituted gamma-diketones, gamma-ketoesters, and gamma-ketoamides in high yields. The in situ formation of a donor-acceptor cyclopropane, via reaction of the enolate of the 1,3-dicarbonyl with an electrophilic silver carbenoid, is proposed as a key process in the catalytic cycle. PMID- 30278301 TI - Circulating levels of tissue factor and the risk of thrombosis associated with antiphospholipid syndrome. AB - The mechanisms behind the severe hypercoagulable state in antiphospholipid syndrome (APS) have not yet been fully elucidated. Knowledge on the etiology of thrombosis in APS is needed to improve treatment. We performed a case control study to evaluate the association of the levels of circulating tissue factor (TF) with thrombotic APS and unprovoked venous thromboembolism (VTE), as compared with controls without a history of thrombosis. Study participants were selected in the same geographic area. Linear regression was used to evaluate possible determinants of TF levels among controls and logistic regression was used to evaluate the association between TF, unprovoked VTE and t-APS. TF levels were grouped into three categories based on: below 50th percentile [reference], between 50-75th percentiles [second category] and 75th percentile [third category]. Two hundred and eighty participants were included in the study; 51 patients with unprovoked VTE, 111 patients with t-APS and 118 control individuals. The levels of TF were not associated with an increased risk of unprovoked VTE, as compared with controls. The adjusted odds ratio for t-APS was 2.62 (95%CI 1.03 to 6.62) with TF levels between 50-75th percentiles and 8.62 (95%CI 3.76 to 19.80) with TF levels above the 75th percentile, as compared with the reference category (below the 50th percentile). In the subgroup analysis, higher levels of TF were associated with both arterial and venous thrombosis in APS and with both primary and secondary APS. Circulating TF is associated with thrombotic complications related to APS, but not with the risk of unprovoked VTE. PMID- 30278302 TI - Differences in muscular and perceptual responses to a neck/shoulder fatiguing task between women and men. AB - Fatigue is a risk factor for the development of work-related musculoskeletal disorders (WMSDs) of the neck/shoulder, and exertion is a state that connects the sensory/affective and physical aspects of fatigue. Relationships between ratings of perceived exertion (RPE) and electromyogram (EMG) signal characteristics have been identified. However, the sex-specific effects on these relationships are unclear and could be affected by personal factors such as skinfold thickness. 28 healthy young adults completed a fatiguing task with the arm held at shoulder height. Neck/shoulder EMG and RPE were collected at the end of each minute. Males showed stronger correlations between RPE with anterior deltoid (AD, rs = 0.37) and upper trapezius (UT, rs = 0.48) EMG, whereas females showed a weak relationship between RPE and UT EMG (rs = 0.22), and no relationship with AD EMG. Significant correlations were observed between biceps EMG and skinfold thickness in both males and females. Findings suggest that neck/shoulder perceived exertion is strongly associated to the activity of shoulder mobilizers (anterior deltoid) in men, whereas in women, it is rather associated to the activity of shoulder stabilizers (upper trapezius), and to a lesser extent. It is possible that in turn, these sex differences affect fatigue adaptation strategies. Skinfold thickness may be an important variable to consider when studying sex-specific characteristics of muscle fatigue. PMID- 30278303 TI - Effect of drought stress on growth parameters, osmolyte contents, antioxidant enzymes and glycyrrhizin synthesis in licorice (Glycyrrhiza glabra L.) grown in the field. AB - Glycyrrhiza glabra L. (licorice) is a medicinal species rich in the specialised plant metabolite glycyrrhizin. It has been previously proposed that drought, which is increasing in importance due to the climatic change and scarcity of water resources, can promote the synthesis of glycyrrhizin. The effects of slight, moderate and intense drought (70, 35 and 23% of the regular irrigation, respectively) on growth parameters, osmolyte content, oxidative stress markers, antioxidant enzymes, glycyrrhizin biosynthesis genes and root glycyrrhizin concentration and contents, have been assessed in five Iranian licorice genotypes grown in the field. Drought decreased progressively biomass and leaf relative water contents, and increased progressively osmolyte (proline, glycine-betaine and soluble sugars) concentrations in leaves and roots. Drought caused oxidative stress in leaves, as indicated by lipid peroxidation and hydrogen peroxide concentrations, and increased the activities of antioxidant enzymes in leaf extracts (catalase, peroxidase, superoxide dismutase and pholyphenoloxidase). Drought promoted the synthesis of glycyrrhizin, as indicated by the increases in the expression of the glycyrrhizin biosynthesis pathway genes SQS1, SQS2, bAS, CYP88D6, CYP72A154 and UGT73, and increased the root concentrations of glycyrrhizin with drought in some genotypes. However, the large decreases in root biomass caused by drought led to general decreases in the amount of glycyrrhizin per plant with moderate and intense drought, whereas the slight drought treatment led to significant decreases in glycyrrhizin content in only one genotype. Under intense drought two of the genotypes were still capable to maintain half of the control glycyrrhizin yield, whereas in the other three genotypes glycyrrhizin yield was 22-33% of the control values. Results indicate that under intense drought, with only 23% of the normal water dose being applied, an appropriate choice of genotype can still lead to acceptable glycyrrhizin yields. PMID- 30278304 TI - Assembling actin filaments for protrusion. AB - Cell migration entails a plethora of activities combining the productive exertion of protrusive and contractile forces to allow cells to push and squeeze themselves through cell clumps, interstitial tissues or tissue borders. All these activities require the generation and turnover of actin filaments that arrange into specific, subcellular structures. The most prominent structures mediating the protrusion at the leading edges of cells include lamellipodia and filopodia as well as plasma membrane blebs. Moreover, in cells migrating on planar substratum, mechanical support is being provided by an additional, more proximally located structure termed the lamella. Here, we systematically dissect the literature concerning the mechanisms driving actin filament nucleation and elongation in the best-studied protrusive structure, the lamellipodium. Recent work has shed light on open questions in lamellipodium protrusion, including the relative contributions of nucleation versus elongation to the assembly of both individual filaments and the lamellipodial network as a whole. However, much remains to be learned concerning the specificity and relevance of individual factors, their cooperation and their site-specific functions relative to the importance of global actin monomer and filament homeostasis. PMID- 30278305 TI - Coping via substance use, internal attribution bias, and their depressive interplay: Findings from a three-week daily diary study using a clinical sample. AB - BACKGROUND: The relationship between depression and coping-oriented substance use is extensively documented; however, the cognitive processes moderating this bidirectional relationship are not well-understood. The present study investigated whether internal attribution bias coupled with a tendency to use drugs and/or alcohol to cope predicts increases in depression and daily-levels of general negative affectivity, sadness, and hostility. METHOD: Sixty-seven adults diagnosed with depression were recruited from out-patient treatment settings (66% female, 81% White, Mage = 31, SDage = 13.2). Participants completed measures on substance-related coping, depression, attributional style, and daily affect over a three-week period. RESULTS: Substance use to cope predicted increases in depression among individuals with high-level internal attribution bias. Further, coping via substance use moderated the relationship between internal attribution bias and daily-level sadness, such that sadness was highest among individuals with a high internal attribution bias coupled with greater levels of coping via substance use. A modest, yet, non-significant upward trend in daily-level hostility was also observed. CONCLUSIONS: Results suggested that depressed individuals who habitually perceive themselves as being responsible or blameworthy for negative life events are at an increased risk of worsening depressive symptoms and experiencing greater daily levels of sadness over a relatively brief period of time, particularly, when tending to engage in substance use as a mechanism to cope. This interaction effect can elicit greater daily-level sadness as well. Findings may aid in the identification and treatment of individuals at risk of maintaining or worsening their depressive symptoms. PMID- 30278307 TI - Environmental tobacco smoke exposure among electronic cigarette users. AB - INTRODUCTION: Exposure to environmental tobacco smoke (ETS) from combustible tobacco products causes various diseases and makes quitting smoking more difficult. However, little is known about exposure of e-cigarette users to ETS from combustible tobacco products. This study aimed to investigate e-cigarette users' exposure to ETS from tobacco smokers. METHODS: The association between ETS exposure frequency and different types of smokers including e-cigarette users was examined using ordered logistic regression analysis and nationally representative survey data on 28,765 individuals who were interviewed in the Canadian Tobacco, Alcohol and Drugs Surveys conducted during 2013 and 2015. Survey respondents were classified into one of five smoker types: smokers of tobacco only, dual users of tobacco and e-cigarettes, users of e-cigarette only, former smokers and never smokers. The analyses were conducted using the entire sample and by age group. RESULTS: Young to mid-age (15-54) dual users of both regular cigarettes and e cigarettes have higher ETS exposure than even tobacco smokers. Young to mid-age single users of e-cigarettes are less exposed to ETS than tobacco smokers, but still have higher ETS than never smokers. At older age (55+), both dual and single e-cigarette users face similar risks of ETS exposure as tobacco smokers. CONCLUSIONS: E-cigarette users are at high risk of ETS exposure. Policies that target the behaviour of e-cigarette users as well as the environments surrounding them to address their high ETS exposure risk would be beneficial. PMID- 30278306 TI - Implementing peer recovery services for overdose prevention in Rhode Island: An examination of two outreach-based approaches. AB - BACKGROUND: Rhode Island has the tenth highest rate of accidental drug overdose deaths in the United States. In response to this crisis, Anchor Recovery Center, a community-based peer recovery program, developed programs deploying certified Peer Recovery Specialists to emergency departments (AnchorED) and communities with high rates of accidental opioid overdoses (AnchorMORE). OBJECTIVES: The purpose of this paper is to describe AnchorED and AnchorMORE's activities and implementation process. METHODS: AnchorED data were analyzed from a standard enrollment questionnaire that includes participant contact information, demographics, and a needs assessment. The AnchorED program outcomes include number of clients enrolled, number of naloxone training sessions, and number of referrals to recovery and treatment services. Overdose deaths and naloxone distribution through AnchorMORE were mapped using Tableau software. RESULTS: From July 2016-June 2017, AnchorED had 1329 contacts with patients visiting an emergency department for reported substance misuse cases or suspected overdose. Among the contacts, 88.7% received naloxone training and 86.8% agreed to continued outreach with a Peer Recovery Specialist after their ED discharge. Of those receiving peer recovery services from the Anchor Recovery Community Center, 44.7% (n = 1055/2362) were referred from an AnchorED contact. From July 2016-June 2017, AnchorMORE distributed 854 naloxone kits in high-risk communities and provided 1311 service referrals. CONCLUSION: These findings indicate the potential impact peer recovery programs may have on engaging high-risk populations in treatment, overdose prevention, and other harm reduction activities. Additional research is needed to evaluate the reach of implementation and services uptake. PMID- 30278308 TI - Phosphodiesters quaternary ammonium nanoparticles as label-free light scattering probe for turn-off detection of tyrosine. AB - In this contribution, a new highly sensitive and selective sensor of the determination of tyrosine has been proposed based on the downturn effect of light scattering (LS) using phosphodiesters quaternary ammonium nanoparticles (PQANPs). Phosphodiesters quaternary ammonium (PQA), one of Gemini zwitterionic surfactants, self-aggregated into the micelle named as PQANPs, which generated strong LS signal in aqueous solution under the optimum condition. Interestingly, the powerful LS intensity of PQANPs with the maximum peak located at 391 nm significantly decreased after introducing trace amount of tyrosine. The decreased value of the LS intensity of the PQA-tyrosine system (DeltaILS) was in proportion to tyrosine concentration in the ranges from 5.5 * 10-8 mol/L to 4.68 * 10-6 mol/L, with a detection limit of 1.38 * 10-8 mol/L. Based on this decreased LS situation, the novel approach of the determination of tyrosine was first developed. The reaction mechanism for the interaction between PQANPs and tyrosine was also investigated. Moreover, the proposed LS assay was applied to the detection of tyrosine concentration in human serum and urine samples with satisfactory results. PMID- 30278309 TI - Transitions within a safe road system. AB - As drivers move through the road transport system they are exposed to a range of different situations and road conditions in a relatively short space of time. Drivers' expectations about what will happen on different types of roads have strong effects on their speed choices, and where they look and what they attend to. As a result it is important to assist drivers to change their expectations when they transition from one road type to another. In this experiment we investigated the effectiveness of different centreline road markings in preparing for a horizontal curve as drivers moved from a motorway to a two-lane rural country road. Fifty individuals were recruited to participate in a video-based simulated driving task to compare three centreline marking types in terms of their effects on speed choice and reactions to a driving hazard (horizontal curve). Although a complex marking previously associated with high risk produced the largest speed reductions during the transition from the motorway, it was the centreline more traditionally associated with rural country roads (dashed white centreline) that was associated with the best hazard reactions post-transition (brake reaction time and speed reduction before a horizontal curve). The findings demonstrated that the look of a road needs to convey a clear and unambiguous message to drivers. The transition to a two-star rural road is best achieved by making the road look like a typical two-star road as soon as possible. PMID- 30278310 TI - Associations between repeated measures of maternal urinary phthalate metabolites during pregnancy and cord blood glucocorticoids. AB - BACKGROUND: Previous studies have suggested that phthalates might disrupt fetal steroidogenesis. However, the evidence of the effects of prenatal phthalate exposure across pregnancy on fetal glucocorticoids was insufficient. OBJECTIVE: We investigated the associations between urinary phthalate metabolites across pregnancy and cord blood glucocorticoids in a prospective birth cohort. METHODS: Our study included 553 mother-infant pairs from a prospective birth cohort conducted in Wuhan, China. Maternal urine samples were collected at 14, 24 and 36 weeks of gestation (mean). Urinary phthalate metabolites and cord blood glucocorticoids (cortisol and cortisone) were measured. Generalized estimating equation models were conducted to explore the relationships of phthalate metabolite concentrations at each trimester and glucocorticoid levels. RESULTS: Among the participants, mono-benzyl phthalate (MBzP) in the first trimester was associated with higher cortisol/cortisone ratio concentrations, and mono-(2-ethyl 5-carboxypentyl) phthalate (MECPP) and mono-(2-ethyl-5-oxohexyl) phthalate (MEOHP) measured in the third trimester were associated with decreased cortisone. Moreover, the associations between phthalates and glucocorticoids varied by sex. Among the female infants, each 10-fold increase in several maternal urinary phthalate metabolite concentrations in 1st and 3rd trimester was associated with the increased glucocorticoid levels with percent changes ranged from 16.2%-55.9%. However, among male infants, each 10-fold increase in maternal urinary MECPP, mono-(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) and MEOHP in 3rd trimester was associated with 20.8%-36.3% decreased cortisol and cortisone levels, respectively. CONCLUSION: We have shown that prenatal phthalate exposure during early and late trimester disrupted the infant steroidogenesis and these associations might be modified by infant sex. To the best of our knowledge, this is the first study to evaluate phthalate exposure at three trimesters during pregnancy in relation to infant glucocorticoids. PMID- 30278311 TI - Environmental styrene exposure and neurologic symptoms in U.S. Gulf coast residents. AB - BACKGROUND: Styrene is an established neurotoxicant at occupational levels, but effects at levels relevant to the general population have not been studied. We examined the neurologic effects of environmental styrene exposure among U.S. Gulf coast residents. METHODS: We used National Air Toxics Assessment (NATA) 2011 estimates of ambient styrene concentrations to assign exposure levels for 21,962 non-diabetic Gulf state residents, and additionally measured blood styrene concentration in a subset of participants (n = 874). Neurologic symptoms, as well as detailed covariate information, were ascertained via telephone interview. We used log-binomial regression to estimate prevalence ratios (PR) and 95% confidence intervals (95% CI) for cross-sectional associations between both ambient and blood styrene levels and self-reported neurologic symptoms. We estimated associations independently for ten unique symptoms, as well as for the presence of any neurologic, central nervous system (CNS), or peripheral nervous system (PNS) symptoms. We also examined heterogeneity of associations with estimated ambient styrene levels by race and sex. RESULTS: One-third of participants reported at least one neurologic symptom. The highest quartile of estimated ambient styrene was associated with one or more neurologic (PR, 1.12; 95% CI: 1.07,1.18), CNS (PR, 1.17; 95% CI: 1.11,1.25), and PNS (PR, 1.16; 95% CI: 1.09,1.25) symptom. Results were less consistent for biomarker analyses, but blood styrene level was suggestively associated with nausea (PR, 1.78; 95% CI: 1.04, 3.03). In stratified analyses, we observed the strongest effects among non White participants. CONCLUSIONS: Increasing estimated ambient styrene concentration was consistently associated with increased prevalence of neurologic symptoms. Associations between blood styrene levels and some neurologic symptoms were suggestive. Environmental styrene exposure levels may be sufficient to elicit symptomatic neurotoxic effects. PMID- 30278312 TI - Molecular expression of Mg2+ regulator TRPM7 and CNNM4 in rat odontoblasts. AB - OBJECTIVE: Magnesium, the second most abundant cation in cellular fluid, is critical for mineralization of hard tissues. Among the molecules involved in cellular Mg2+ homeostasis, functional impairment of Mg2+ permeable ion channel TRPM7 or Mg2+ transporter CNNM4 have been found to result in severe hypomineralization of the enamel and dentin. However, molecular expressions of TRPM7, CNNM4 and their respective homologues have not been fully investigated in adult odontoblasts. DESIGN: Expressions of TRPM6, TRPM7, CNNM1, CNNM2, CNNM3, CNNM4 were screened in acutely dissociated rat odontoblasts by single cell RT PCR. Among these candidates, expression levels of TRPM7 and CNNM4 were compared along the odontoblast layer by immunohistochemical analysis. Finally, the coexpression pattern of TRPM7 and CNNM4 in subcellular regions was examined by immunocytochemical analysis. RESULTS: ScRT-PCR revealed high expression rate of TRPM7 and CNNM4 in odontoblasts, with CNNM4 detected almost exclusively in TRPM7 positive odontoblasts. However, CNNM2 and CNNM3 were detected in only a small population of odontoblasts, and TRPM6 and CNNM1 were not detected even in the pulp tissue. Immunohistochemical analysis revealed higher CNNM4 expression in the apical odontoblast layer than the coronal area, in contrast to the ubiquitous expression of TRPM7. Lastly, immunocytochemical analysis revealed colocalization of CNNM4 with TRPM7 in the odontoblastic process. CONCLUSIONS: CNNM4 and TRPM7 may serve as main Mg2+ regulators in odontoblasts, possibly with selective involvement of CNNM4 in apical dentin formation or mineralization. Colocalization of TRPM7 and CNNM4 in the odontoblastic process suggest functional coupling of these two molecules to maintain Mg2+ homeostasis. PMID- 30278313 TI - Selenium amelioration of arsenic toxicity in rice shows genotypic variation: A transcriptomic and biochemical analysis. AB - The toxic metalloid arsenic (As) is consumed mostly through contaminated rice. Therefore, reducing its accumulation and maintaining nutrient homeostasis in crop plants are imperative to ensure food safety. However, there is a dearth of information on the interrelationship between nutrient homeostasis and the regulatory mechanisms of arsenic-selenium (As-Se) interactive pathways responsible for stress tolerance. In the present study, experiments were conducted in hydroponically grown 12-day-old seedlings of rice (Oryza sativa L.) varieties (Pusa Basmati1 and IR64) treated with arsenite (AsIII) (150 MUM), selenium (SeVI) (20 MUM), and As + Se. It was observed that selenium supplementation ameliorated As toxicity by reducing its accumulation and retrieving As-induced nutrient deficiency. Significant decrease in As accumulation, H2O2 content, and fluorescent intensity of nitric oxide (NO), reactive oxygen species (ROS), and superoxide radical (O2.-) along with cell death with Se supplementation in both rice varieties demonstrated the protective role of Se as a probable ROS quencher. Addition of Se increased the enzyme activities of thiol metabolism and induced differential transcript accumulation patterns of sulfur-related genes. Nutrient level positively correlated with the differential expression pattern of NPK-related genes that play roles in metabolism and nutrient availability in both varieties. Though Pusa Basmati1 (PB1) showed higher tolerance to As, IR64 overcomes As toxicity more efficiently than PB1 in the presence of Se, which highlights that IR64 is a better performer in the presence of Se. Overall, this study provides novel insight into the role of Se in As-stressed rice genotypes through alteration of nutrient transporters and thiol-related genes. PMID- 30278314 TI - Accumulation of water-soluble carbohydrates and gene expression in wheat stems correlates with drought resistance. AB - In order to understand the effects of sugar metabolism on drought resistance in wheat, two wheat cultivars with different levels of drought resistance were used in this study. We investigated the accumulation pattern of water-soluble carbohydrates (WSC) and expression profiles of twelve fructan metabolism-related genes in peduncle (PED), penultimate (PEN), and lower internode (LOW) stem tissues under drought stress. LH7, a higher drought-resistance cultivar, contained a higher stem dry weight and higher content of WSC in PED, PEN, and LOW tissues, while XN979, a lower drought-resistance cultivar, contained lower values. The tissues from LOW internodes had the highest WSC content, while PED had the lowest. The mRNA levels of genes encoding fructan synthesis-related enzymes, sucrose: sucrose 1-fructosyltransferase (1-SST), sucrose: fructan 6 fructosyltransferase (6-SFT), and fructan: fructan 1- fructosyltransferase (1 FFT) showed higher expression levels at early time points following stress, whilst the genes encoding degradation-related enzymes, fructan exohydrolases (1 FEH), and invertase (INV), showed higher expression at a later time point. Compared with XN979, LH7 showed higher expression levels of genes encoding fructan synthesis-related enzymes at all growth stages, whilst the expression of 1-FEH-W3, 6-FEH, and INV3 were higher at a later stage; these expression levels would benefit fructan accumulation and remobilization at early and later stages, respectively. Drought stress induced most of fructan metabolism related genes expression level decreasing in LH7 PED, but enhancing in LH7 LOW part at early time points following stress. The results confirm that there are complex, coordinated expression patterns of fructan synthesis- and degradation-related genes in stems under drought stress. In summary, 1-SST-A2, 6-SFT, 1-FFT-A, 1-FEH W3, 6-FEH, and INV3 play important roles in fructan accumulation. In addition, higher expression of genes related to fructan synthesis and degradation occurs during early and later stages of drought stress, respectively, enhancing the drought resistance of wheat cultivar LH7. PMID- 30278315 TI - GABA enhances physio-biochemical metabolism and antioxidant capacity of germinated hulless barley under NaCl stress. AB - The effects of exogenous gamma-aminobutyric acid (GABA) on the endogenous GABA metabolism and antioxidant capacity of germinated hulless barley (Hordeum vulgare L.) under NaCl stress were investigated. The results showed that all of the GABA treatments could alleviate the growth inhibition and oxidative damage by NaCl stress, with 0.5 mM being the most effective concentration. The GABA-treated barley seedlings exhibited a significantly higher content of endogenous GABA and other free amino acids, especially proline, which resulted from the changes in corresponding enzyme activity. The phenylalanine ammonia lyase (PAL), cinnamic acid 4-hydroxylase (C4H), and 4-coumarate coenzyme A ligase (4CL) activities also increased in GABA-treated barley, which led to higher total phenolic content and antioxidant capacity than that of the control barley. These results indicate that GABA treatment may be an effective way to relieve salt stress as it induces the accumulation of endogenous GABA and proline and total phenolic content, thus enhancing the antioxidant capacity.

AB - A new type of angularly selective electron detector for use in a scanning electron microscope is presented. The detector leverages a digital micromirror device (DMD) to take advantage of the benefits of two-dimensional (2D) imaging detectors and high-bandwidth integrating detectors in a single optical system. The imaging detector provides direct access to the diffraction pattern, while the integrating detector can be synchronized to the microscope scan generator providing access to a real space image generated by integrating (pixel-by-pixel) a portion of the diffraction pattern as quantitatively defined by the DMD. The DMD, in effect, takes the place of the objective aperture in a transmission electron microscope (TEM) or an annular detector in a scanning transmission electron microscope (STEM), but has the distinct advantage that it can be programmed to take any shape in real time. Proof-of-principle data collected with the detector show diffraction contrast in samples ranging from a polycrystalline gold film to monolayer graphene.

AB - We investigate the ferroelectric properties and crystal structures of Bi3TaTiO9 (BTTO) thin films deposited on single-crystal Nb-doped (100) SrTiO3 substrates via pulsed laser deposition. The BTTO films exhibited either a (001)-epitaxial crystalline structure or a mixed a- and c-oriented polycrystalline structure depending on the substrate temperature. The ferroelectric polarization and piezoelectric coefficient of the mixed a- and c-oriented film were larger than those of the (001)-epitaxial film because its polar axis was perpendicular to the c-axis. Vertical and lateral piezoresponse force microscopy studies indicate that the ferroelectric domains of the (001)-epitaxial film were all parallel to the in plane orientation, whereas the mixed a- and c-oriented film comprised both square grains with in-plane-oriented ferroelectric domains and longish grains with ferroelectric domains out of orientation with the plane.

AB - We report simultaneous Force -static deflection of the cantilever-, Force Gradient and Scanning Tunneling topography images of Si(111)(7 * 7) surface using an off-resonance small amplitude non-contact atomic force microscopy technique with improved force sensitivity. The signal-to-noise ratio of the fiber interferometer used to detect the deflections of the cantilever was improved by applying an RF-modulation into the diode laser, which suppresses the noise in the laser. The measured sensitivity of ~20 fm/?Hz allows us to obtain atom resolved images of the surface in static deflection of the cantilever, simultaneously with the other imaging channels. PMID- 30278319 TI - Rapid and longer-term antidepressant effects of repeated-dose intravenous ketamine for patients with unipolar and bipolar depression. AB - OBJECTIVE: Single-dose intravenous (IV) injection of ketamine has shown rapid but transient antidepressant effects. The strategy of repeated-dose ketamine infusions to maintain antidepressant effects has received little systematic study. This study was conducted to examine the efficacy and tolerability of six ketamine infusions in Chinese patients with unipolar and bipolar depression. METHODS: Ninety seven patients with unipolar (n = 77) and bipolar (n = 20) depression received repeated ketamine infusions (0.5 mg/kg over 40 min) with continuous vital sign monitoring. Depressive symptoms were measured by the Montgomery-Asberg Depression Rating Scale (MADRS). Suicidal ideation was assessed using the Scale for Suicidal Ideations (SSI)-part 1. Anxiety symptoms were evaluated with the 14-item Hamilton Anxiety Scale (HAMA). Adverse psychopathological and dissociative effects were assessed using the Brief Psychiatric Rating Scale (BPRS)-positive symptoms and Clinician Administered Dissociative States Scale (CADSS), respectively. Patients were assessed at baseline, 4 and 24 h, and 3, 4, 5, 6, 8, 9, 10, 11, 12, 13 and 26 days. RESULTS: After six ketamine infusions, the response and remission rates were 68.0% and 50.5%, respectively. There were significant decreases in MADRS, SSI-part 1, and HAMA scores within four hours following the first ketamine infusion, and the decreases were sustained over the subsequent infusion period. The nonresponder subgroup manifested rapid significant improvement in suicidal ideations throughout the course of treatment. After the six ketamine infusions, the response was positively associated with the response at 24 h after the first infusion (OR = 8.94), personal income >=4000 yuan/month (OR = 3.04), and no history of psychiatric hospitalization (OR = 3.41). Only CADSS scores had a mild but marginally significant increase after the first infusion but with a significant BPRS score decrease. CONCLUSION: Six ketamine infusions were safe and effective in patients with unipolar and bipolar depression. The rapid and robust antidepressant and antisuicidal effects of ketamine infusion within four hours were sustained following the subsequent infusions. PMID- 30278320 TI - Internalizing symptoms and dating violence perpetration in adolescence. AB - BACKGROUND: Increasing evidence suggests an association between internalizing symptoms and violence against others. It remains unknown whether this link exists in the context of romantic relationships. In the current study, we tested whether anxiety and depression were associated over time with adolescent dating violence perpetration. METHODS: The sample included 238 Canadian adolescents (42% boys). Using a longitudinal design, their anxiety, depressive symptoms, and dating violence perpetration were annually assessed from age 14 to 15 years. RESULTS: Cross-lagged analyses revealed effects from anxiety and depressive symptoms to dating violence one year later (beta = 0.27, p < .001; and beta = 0.14, p = .04, respectively). No reversed cross-lagged paths were found from dating violence to subsequent anxiety or depression. CONCLUSIONS: Our findings underscore the predictive value of internalizing symptoms on dating violence perpetration. Reducing internalizing symptoms and improving coping strategies are important targets for the prevention of dating violence. PMID- 30278322 TI - High delusional ideation is associated with false pictorial memory. AB - BACKGROUND AND OBJECTIVES: To assess the relationship between false memories and schizotypal experiences in healthy volunteers. Previous research has examined a number of schizotypal dimensions and experiences and found a variety of results. Our aim was to determine the specificity of these associations by giving participants a schizotypy measure which tapped positive, negative and disorganised dimensions (O-LIFE) and another which focused on delusional ideation (PDI). METHODS: A new memory task was used consisting of images of everyday items, separated into categories. At test participants were presented with pictures which had been seen in the study phase, related lures (additional items from the same categories but which were new) and new items which were not from these categories. RESULTS: Positive correlations were found between scores on the positive dimension of schizotypy/delusional ideation and proportion of false memories. Moreover, these participants also had a greater tendency to respond with the highest confidence old response, regardless of the status of the item. No significant correlations were found with the other dimensions of schizotypy. LIMITATIONS: The confidence finding differs somewhat from previous research, which has found more confidence in memory errors and less confidence in correct responses in schizophrenia. It is unclear the reason(s) for this discrepancy. CONCLUSIONS: Increased false memory is associated with the positive dimension of schizotypy and delusional ideation and not the disorganised or negative dimensions. Furthermore, our results suggest that those high in positive schizotypy/delusional ideation require less evidence before they are willing to call an item old. PMID- 30278321 TI - Social media social comparison and identity distress at the college transition: A dual-path model. AB - INTRODUCTION: Social media provide a convenient platform for social comparison, an activity that should play an important role in youth's identity development at the transition to college. Yet, the identity implications of online social comparison have not been thoroughly explored. Drawing on the theories of social comparison, introspective processes, and identity distress, we examined a dual path model. The paths from two types of social media social comparison (i.e., comparison of ability and comparison of opinion) to two introspective processes (i.e., rumination and reflection) and finally to identity distress were tested. METHODS: Short-term longitudinal survey data were collected from 219 college freshmen at a state university in the United States of America (Mage = 18.29, S.D. = 0.75; 74% female; 41% White, 38% Black). RESULTS: Social comparison of ability on social media had a positive association with concurrent rumination, which predicted higher identity distress. In contrast, social comparison of opinion on social media had a positive relationship with concurrent reflection, which, however, did not predict identity distress. CONCLUSION: Results indicate that different types of online social comparison yield distinct implications for young people's identity development. Largely, the study reaffirms the recently rising call for distinguishing the competition-based social comparison of ability from the information-based social comparison of opinion. At the same time, the study expands current knowledge of why these forms of social comparison may lead to differential outcomes, namely through the type of introspection they induce. PMID- 30278323 TI - A multidimensional analytical approach based on time-decoupled online comprehensive two-dimensional liquid chromatography coupled with ion mobility quadrupole time-of-flight mass spectrometry for the analysis of ginsenosides from white and red ginsengs. AB - Here, time-decoupled comprehensive two-dimensional ultra-high liquid chromatography (UHPLC) coupled with an ion mobility (IM)-high resolution mass spectrometer (HRMS) was established and used to analyze ginsenosides from the main roots of white ginseng (WG) and red ginseng (RG), which enabled the separation of complex samples in four dimensions (2D-LC, ion mobility, and mass spectrometry). The incompatibility of mobile phases, dilution effect, and long analysis time, which are the main shortcomings of traditional comprehensive 2D-LC methods, were largely avoided in this newly established 2D-UHPLC method. The orthogonality of this system was 55%, and the peak capacity was 4392. Under the optimized 2D-UHPLC-IM-MS method, 201 ginsenosides were detected from white and red ginseng samples. Among them, 10 pairs of co-eluting isobaric ginseng saponins that were not resolved by 2D-UHPLC-HRMS were further resolved using 2D-UHPLC-IM MS. In addition, 24 ginsenoside references were analyzed by UHPLC-IM-MS to obtain their collision cross section (CCS) values and ion mobility characteristics. Finally, the established new method combined with multivariate statistical analysis was successfully applied to differentiate WG and RG, and 9 ginsenosides were found to be the potential biomarkers by S-Plot and the values of max fold change, which could be used for classifying WG and RG samples. Overall, the obtained results demonstrate the applicability and potential of the established time-decoupled online comprehensive 2D-UHPLC-IM-MS system, and it will be extended to the analysis of other targeted or untargeted compounds, especially co eluting isomers in more herbal extracts. PMID- 30278324 TI - Determination of total and free ceftolozane and tazobactam in human plasma and interstitial fluid by HPLC-UV. AB - Ceftolozane/tazobactam is a new cephalosporin/beta-lactamase inhibitor combination. An HPLC-UV method is described for the determination of total and free ceftolozane and tazobactam in human plasma and in microdialysate of subcutaneous tissue, respectively. Separation was performed using a reversed phase column with phosphate buffer/acetonitrile as eluent and photometric detection at 260 nm (ceftolozane) or 220 nm (tazobactam). Linearity has been shown down to ceftolozane/tazobactam 0.1/0.05 mg/L in plasma and 0.03/0.015 mg/L in saline, respectively. The plasma protein binding of both drugs as determined by ultrafiltration was less than 10%. Temperature, pH or relative centrifugation force (up to 3000 x g) had no significant impact on the protein binding. The method was applied to the determination of ceftolozane and tazobactam in plasma and interstitial fluid of healthy volunteers following intravenous infusion of ceftolozane/tazobactam 1.0/0.5 g. PMID- 30278325 TI - Single vial cold kits optimized for preparation of gastrin releasing peptide receptor (GRPR)-radioantagonist 68Ga-RM2 using three different 68Ge/68Ga generators. AB - 68Ga-RM2 is a gastrin releasing peptide receptor (GRPR) antagonist PET (positron emission tomography) radiotracer which is being investigated in clinical trials as a potential prostate cancer imaging agent. Simple, one-step kit formulation of 68Ga-RM2 would facilitate multicentre trials and allow easier integration in hospital radiopharmacy. Herein we report development of three sets of single-vial RM2 cold kits validated for formulation with three respective 68Ge/68Ga generators eluted in 0.6 M, 0.1 M and 0.05 M HCl (hydrochloric acid). Cold kits of varied pH (2, 3, 4 and 5) were prepared using 2 M sodium acetate for three different 68Ge/68Ga generators to determine influence of pH on the radiochemical yield of 68Ga-RM2. Buffer content was optimized with respect to volume of 68GaCl3 eluate to be added (1 mL/2 mL/ 5 mL). Sterility, apyrogenicity and long term stability of cold kits; in vitro and serum stability of 68Ga-RM2 were investigated. In vitro cellular uptake and inhibition studies were performed to demonstrate the specificity of kit-formulated 68Ga-RM2. The radiochemical yield of 68Ga-RM2 formulated from three different generators was observed to be maximum at pH 3 (99 +/- 0.5%). Cold kits stored for 6 months at 0 degrees C also resulted in high radiochemical yield. 68Ga-RM2 exhibited excellent in vitro stability (1 h) and serum stability (1 h). In vitro cellular uptake of 5 +/- 0.8% in PC3 cells with >85% inhibition was observed for the 68Ga-RM2 radiotracer indicating its specificity towards GRPR expression. These simple, robust kits shall allow hospitals with different generators to participate in clinical studies of 68Ga-RM2 for screening of GRPR-expressing prostate tumors. PMID- 30278326 TI - Kinetics of spontaneous water-N2 imbibition in carbon molecular sieves. AB - In this study, a new kinetic model of spontaneous liquid-gas imbibition (SLGI) for microporous adsorbents has been developed. With three carbon molecular sieves (CMS) as adsorbents, N2 as gas probe and water as liquid probe, the kinetics of spontaneous water-N2 imbibition in CMS has been investigated at atmospheric pressure, and the applicability of the kinetic model to the SLGI has been assessed. The influences of the particle size of CMS and the experimental temperature in the range of 20-35 degrees C on the imbibition process have been analyzed based on the kinetic model. The relations between the kinetic parameters of the SLGI and the microporous parameters of the CMS obtained by CO2 adsorption at 273 K have been elucidated. The results indicate that the imbibition process is controlled by the diffusion of the water molecules into and N2 out of the micropores and the adsorption of the water on the pore surface of the CMS. The equilibrium gas recovery is positively related with the micropore volume, and the gas recovery rate depends mainly on the micropore size of the CMS. PMID- 30278327 TI - Magnetic nano-nets for capture of microbes in solution based on physical contact. AB - Self-assembly of Au nanoparticles with Fe ions is used to develop magnetic nano nets similar to fishing nets for capture and removal of microbes in aqueous medium. The nano-nets have a high aspect ratio, span microns in length with openings of 80-300 nm. This allows them to sample the liquid medium even at low volume fraction and also entrap the microbes in the solution. The nets and the trapped microbes can be effectively pulled from the solution by using an off the shelf magnet. Since the capture is based on physical contact, the nano-nets overcome the ability of the microbes to develop resistance to the cytotoxic effects of chemical compounds and nanomaterials. Using the nano-nets an absolute inactivation of 0.9 is achieved in 5 min. in a non-deaerated solution with Escherichia coli (E. coli). Further the removal of the nano-nets along with the captured microbes also predominantly eliminates the nanomaterial from the aqueous medium for future use. PMID- 30278328 TI - Shape-controlled synthesis of well-dispersed platinum nanocubes supported on graphitic carbon nitride as advanced visible-light-driven catalyst for efficient photoreduction of hexavalent chromium. AB - Photocatalytic degradation of environmental pollutants by using semiconductor based photocatalysts offers great potential for remediation of toxic chemicals. For an economical and eco-friendly method to eliminate hexavalent chromium (Cr(VI)), favourable catalysts own high efficiency, stability and capability of harvesting light. Combination of metal with semiconductor is a promising route to improve the photocatalytic performance for Cr(VI) reduction. Herein, well dispersed platinum (Pt) nanocubes (NCs) were synthesized by a facile one-step hydrothermal method with poly-l-lysine (PLL) as the growth-directing agent, followed by their uniform dispersion on graphitic carbon nitride (g-C3N4). Their morphology, crystal structure, chemical composition, and formation mechanism were mainly characterized by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). The hybrid nanocomposite was further explored for photocatalytic reduction of Cr(VI) to trivalent chromium (Cr(III)) under visible light at room temperature, by using formic acid (HCOOH) as a reducing agent, showing great improvement in photocatalytic activity and reusability, outperforming the referenced g-C3N4 and home-made Pt black/g-C3N4 catalysts. The effects of various experimental parameters and the proposed mechanism are discussed in detail. PMID- 30278329 TI - Facile approach to develop durable and reusable superhydrophobic/superoleophilic coatings for steel mesh surfaces. AB - Oil spills on the surfaces of bodies of water are now a great concern as they affect marine creatures and the ecosystem. Therefore, a facile technique for removal of oil from water is of much interest. In this study, superhydrophobic and superoleophilic coating is synthesized on stainless steel mesh via chemical etching using a mixture of FeCl3 and HCl followed by treatment with hexadecyltrimethoxysilane. Surface morphology analysis shows the presence of flower like microstructures on the surface after treatment. Superhydrophobic and superoleophilic properties have been achieved on stainless steel mesh with water static contact angle of 167 degrees +/- 3 degrees , water tilting angle of 6 degrees +/- 1 degrees , and oil static contact angle of nearly 0 degrees . The coating shows excellent thermal, chemical and mechanical stability. Kerosene water and hexane-water mixtures were successfully separated via a simple filtering process using coated steel mesh with a separation efficiency of more than 98%. This approach can be implemented on any shape or size of stainless steel mesh and will have industrial applications. PMID- 30278330 TI - Controllable construction of multishelled p-type cuprous oxide with enhanced formaldehyde sensing. AB - Hollow metal oxide semiconductor (MOS) materials with controllable shells have attracted increasing attention because of their interesting properties and potential applications in sensors, catalysis, biology, etc. Cuprous oxide (Cu2O), which is a typical p-type semiconductor material, has four kinds of nanostructures (i.e., single-, double-, triple-, and quadruple-shelled spheres) and was successfully synthesized by the simple regulation of hexadecyl trimethyl ammonium bromide (CTAB) concentration. All as-obtained samples were at the nanometer level, and the hollow layers were also located between the two shells of the Cu2O nanostructures. The structural evolution and formation mechanism of the core-in-hollow multishelled nanostructure were also studied in this work. Moreover, the gas sensing performance of four kinds of materials was measured. The performance of the quadruple-shelled Cu2O-based formaldehyde (HCHO) sensor was greater than that of other sensors. The results indicated that the well defined multishelled structure may significantly enhance HCHO detection by facilitating the gas adsorption quantity and transport rate. PMID- 30278331 TI - Rescuing the CFTR protein function: Introducing 1,3,4-oxadiazoles as translational readthrough inducing drugs. AB - Nonsense mutations in the CFTR gene prematurely terminate translation of the CFTR mRNA leading to the production of a truncated protein that lacks normal function causing a more severe form of the cystic fibrosis (CF) disease. About 10% of patients affected by CF show a nonsense mutation. A potential treatment of this alteration is to promote translational readthrough of premature termination codons (PTCs) by Translational Readthrough Inducing Drugs (TRIDs) such as PTC124. In this context we aimed to compare the activity of PTC124 with analogues differing in the heteroatoms position in the central heterocyclic core. By a validated protocol consisting of computational screening, synthesis and biological tests we identified a new small molecule (NV2445) with 1,3,4 oxadiazole core showing a high readthrough activity. Moreover, we evaluated the CFTR functionality after NV2445 treatment in CF model systems and in cells expressing a nonsense-CFTR-mRNA. Finally, we studied the supramolecular interactions between TRIDs and CFTR-mRNA to assess the biological target/mechanism and compared the predicted ADME properties of NV2445 and PTC124. PMID- 30278332 TI - Transformation of asiatic acid into a mitocanic, bimodal-acting rhodamine B conjugate of nanomolar cytotoxicity. AB - Based on their biological activity natural products continue to represent optimal lead structures for the development of novel drug candidates. We focused on the syntheses of several derivatives of the triterpene asiatic acid and on the evaluation of their cytotoxic activity in a photometric sulforhodamin B assay. Especially, benzamide 2 and rhodamine B conjugate 11 show a distinct cytotoxicity for several human tumor cell lines, e.g. EC50 (A2780) = 110 +/- 1 nM and EC50 (A2780) = 8 +/- 2 nM, respectively. Interestingly, compound 11 showed for two human tumor cell lines (HT29 and 518A2) non-linear, bimodal dose-response relationships. PMID- 30278333 TI - Development of high potent and selective Bcl-2 inhibitors bearing the structural elements of natural product artemisinin. AB - By taking advantage of the apoptosis-inducing capacity of artemisinin derivatives, we developed several series of compounds by merging the basic structural elements of the natural product artemisinin into the P2 interaction pocket of the clinically prescribed Bcl-2 inhibitor venetoclax. Most of the new compounds displayed improved biochemical potency against Bcl-2 and high selectivity over Bcl-xL. Specifically, compounds 27c and 34c were found to be the most potent with IC50 values less than 2.0 nM. Unfortunately, these compounds only showed moderate antiproliferative effects against Bcl-2 dependent cells. Though further structural optimization is needed to improve the cellular absorptive permeability, the current approach represents an alternative strategy to develop novel Bcl-2 inhibitors with greater selectivity over Bcl-xL, which is related to the off-target adverse effects of venetoclax. PMID- 30278334 TI - The role of universities in attracting male students on to pre-registration nursing programmes: An electronic survey of UK higher education institutions. AB - The UK nursing workforce is facing a crisis. More nurses are leaving than entering the profession, and there are tens of thousands of unfilled vacancies. Political factors are having a significant impact on numbers, in particular the decision to withdraw bursaries for nursing undergraduates, and a steep decline in EU nurses registering to work in the UK post-Brexit. Against this backdrop, there is a stark gender imbalance in the workforce, with only around 11% of registered nurses being male. We surveyed UK higher education institutions to try to identify whether the gendered nature of nursing was considered a concern and whether steps were being taken to address it. We sent an electronic survey to every UK university offering undergraduate nurse training validated by the Nursing and Midwifery Council (NMC). With a response rate of 42%, the majority of respondents felt that nursing departments should take much more responsibility to increase the proportion of male nurses entering the nursing profession. More needs to be done to diversify the workforce and make nursing an appealing career choice for men and women. PMID- 30278335 TI - Feed-forward: Paving ways for students' subsequent learning. AB - BACKGROUND: Written feedback assists students in refining their future academic work. However, students prefer having feed-forward instead of feedback by their instructors that are the comments provided to them on drafts prior to the actual assignment submission. The current literature describes two common ways to convey feed-forward: the foremost one is on outlines while the second is on drafts. However, no existing literature had been found yet for sufficient guidance on the ideal approach of feed-forward to facilitate students' subsequent learning. DESIGN: A Quasi-experimental study design was employed to determine the effectiveness of feed-forward on outline versus drafts. SETTING: Study was conducted in a private nursing institution in Karachi, Pakistan. PARTICIPANTS: 118 third-year undergraduate nursing students participated in the study. METHODS: Using consecutive sampling, 118 students were enrolled and equally divided in to two groups, each comprising of 59 students in the control and intervention arm. Control group received feed-forward through standard practice i.e. on their assignment outline while the intervention group received feed-forward on the draft of their scholarly paper. RESULTS: The performance of intervention arm had an upper hand over that of control wing as portrayed by their increased overall assignment and academic writing scores (of students on IELTs bands). The set outcomes also reflected better results in terms of the (reduced) frequency of visits to their instructors for clarification of written feedback. All in all, this research deduced that feed-forward on drafts is far more beneficial in contrast to that on an outline as it reinforces students' learning. CONCLUSION: The study findings affirmed that feed-forward is a useful strategy to enhance students' subsequent learning. PMID- 30278336 TI - Incomplete uptake of EGFR mutation testing and its impact on estimation of mutation prevalence in patients with non-squamous NSCLC: A population-based study in New Zealand. AB - BACKGROUND: Epidermal Growth Factor Receptor (EGFR) mutation testing is recommended for patients with non-squamous non-small cell lung cancer (NSCLC) but not all eligible patients get tested, which may bias the mutation prevalence estimated. This study aims to examine trends in the uptake of EGFR mutation testing in patients with non-squamous NSCLC in New Zealand; to develop a composite metric that quantifies the influences of demographic and clinico pathological factors on the testing uptake; and to estimate the prevalence of EGFR mutation if all patients were tested. METHODS: This population-based study involved all patients who were diagnosed with non-squamous NSCLC in four health regions in New Zealand between January 2010 and December 2015. Eligible patients were identified from the New Zealand Cancer Registry and information on EGFR mutation testing was obtained through linkage to TestSafe, a clinical information sharing service, and laboratory records. RESULTS: Of 2701 eligible patients, 1059 (39.2%) were tested for EGFR mutation. The testing prevalence increased (3.7% in 2010 to 64.6% in 2014) and the influences of demographic and clinic-pathological factors decreased from 2010 to June 2014, and remained stable afterward. Of the tested patients, 229 (21.6%) were mutation positive with a decreasing trend observed from 2010 (43.8%) to June 2014 (16.8%). The best-fit log-linear model estimated the prevalence of EGFR mutation, if all patients were tested, as 15.5% (95% CI: 13.2%-18.0%). CONCLUSION: The methods described here allowed a more accurate estimation of the prevalence of EGFR mutation. PMID- 30278337 TI - Knowledge and practice of computed tomography exposure parameters amongst radiographers in Jordan. AB - OBJECTIVE: To investigate the knowledge and practice of computed tomography (CT) radiographers working in Jordan. MATERIALS AND METHODS: This Institutional Review Board (IRB) approved study disseminated a questionnaire via social media and recruited 54 Jordanian CT radiographers. The questionnaire comprised 36 questions divided into four sections: demographics; an evaluation of knowledge regarding CT exposure; modifications to CT exposure for paediatric patients; dose units and diagnostic reference levels (DRLs). Descriptive and inferential statistics including Chi-square tests, Mann-Whitney U tests, independent samples t-tests and Kruskal-Wallis H tests were employed. Statistical significance was considered below p < 0.05. RESULTS: The 54 participants had various qualifications, with the majority holding a Bachelor's degree (n = 35, 64.8%) and the rest holding a Diploma (n = 19, 35.2%). In order to pass the questionnaire, participants needed to score 13 correct answers. The overall number of radiographers who correctly passed the questionnaire was 48 (88.9%). None of the participants correctly stated all the DRL values for chest, abdomen and brain CT. However, four out of 54 respondents (7.4%) knew the chest DRL value, three (5.6%) participants correctly estimated the abdominal DRL value but only two (3.7%) knew the DRL for the brain. CONCLUSION: Good general knowledge was found amongst radiographers regarding the relationship of each exposure parameter to the image quality and patient dose. However, there was poor knowledge of diagnostic reference levels and the order of the organ radiation sensitivity. The need for CT radiographers to undertake further education that focuses on radiation exposure in CT is highlighted.

For example, having a reliable way of measuring the severity of the case, determining which remedial program is aligned with a patient's needs, and measuring of treatment processes. There is potential for brain-computer interface (BCI) applications to enhance speech therapy sessions by providing objective insights and real-time visualization of brain activity during the sessions. This paper presents a study on emotional state detection during speech pathology. The goal of this study is to investigate affective-motivational brain responses to stimuli in children who stutter. To this end, we conducted an experiment that involved recording frontal electroencephalography (EEG) activity from fifteen children with stuttering whilst they looked at visual stimuli. The contribution of our study is to provide a comprehensive background and a framework for emotional state detection experiments as assessment and monitoring tool in speech pathology. It mainly discusses the feasibility and potential benefits of applying EEG-based emotion detection in speech-language therapy contexts of use. The findings of our research indicate that emotional recognition using non-invasive EEG-based BCI system is sufficient to differentiate between affective states of individuals in treatment contexts. PMID- 30278339 TI - Prognostication of metastatic death in uveal melanoma patients: A Markov multi state model. AB - BACKGROUND/AIMS: Uveal melanoma is fatal in almost 50% of patients. We previously developed a prognostic model to predict all-cause mortality. The aim of this study was to improve our model by predicting metastatic death as a cause-specific event distinct from other causes of death. METHODS: Patients treated in Liverpool were included if they resided in England, Scotland or Wales and if their uveal melanoma involved the choroid. They were flagged at the National Health Service Cancer Registry, which automatically informed us of the date and cause of death of any deceased patients. A semiparametric Markov multi-state model was fitted. Two different baseline hazard rates were assumed, with state transition-specific covariates. For both failure types, age at treatment and sex were used. For the metastatic death case, these factors were added: anterior margin position, largest basal tumour diameter, tumour thickness, extra-ocular extension, presence of epithelioid melanoma cells, presence of closed connective tissue loops, increased mitotic count, chromosome 3 loss, and chromosome 8q gain. Missing data required a multiple-imputation procedure. RESULTS: The cohort comprised 4161 patients, 893 of whom died of metastastic disease with another 772 dying of other causes. The optimism-corrected, bootstrapped C-index for metastatic death prediction was 0.86, denoting very good discriminative performance. Bootstrapped calibration curves at two and five years also showed very good performance. CONCLUSIONS: Our improved model provides reliable, personalised metastatic death prognostication using clinical, histological and genetic information, and it can be used as a decision support tool to individualize patient care in a clinical environment. PMID- 30278340 TI - A novel electrochemical aptasensor based on nontarget-induced high accumulation of methylene blue on the surface of electrode for sensing of alpha-synuclein oligomer. AB - This study describes a novel electrochemical aptasensor for detection of alpha synuclein (alpha-syn) oligomer, an important biomarker related to Parkinson's and Alzheimer's diseases. The sensing platform is based on exonuclease I (Exo I), terminal deoxynucleotidyl transferase (TdT) and methylene blue. The aptasensor exploits the improved sensitivity because of applications of TdT and Exo I and also a label-free aptamer (Apt). Furthermore, direct immobilization of complementary strand of aptamer (CS) instead of Apt on the surface of electrode prohibits Apt self-assembled monolayer aggregation and keeps the function of the Apt. In the absence of alpha-syn oligomer, TdT enhances lengths of Apt and CS and so, increases accumulation of methylene blue as redox agent on the surface of electrode, leading to a strong current signal. While in the presence of alpha-syn oligomer, Exo I digests CS on the electrode surface, resulting in less accumulation of methylene blue on the electrode surface and a weak current signal. The relative electrochemical signal of the aptasensor increased linearly with the logarithm of alpha-syn oligomer concentration in the range from 60 pM to 150 nM. The detection limit was 10 pM. Furthermore, the sensor showed high precision and repeatability for detection of alpha-syn oligomer in serum samples.

AB - A simple, facile and sensitive photoelectrochemical (PEC) bioassay protocol for metronidazole (MNZ) detection in common oral medicine samples has been proposed under visible-light irradiation, where novel hierarchical coral-like g-C3N4 nanoarchitectures (cg-C3N4) have been first explored as PEC sensing platform. Featured with the unique nanostructures (e.g., interlaced porous network architecture, and open boundaries), the as-formed cg-C3N4 nanoarchitectures not only efficiently inhibit the recombination of photogenerated electron-hole but also enable the immobilization of capture antibodies as well as the antibody antigen binding efficiency fluently, thus amplifying the photocurrent response. This newly constructed PEC immunoassay displays excellent performance for MNZ determination with high sensitivity and selectivity. Under the optimal condition, this bioassay protocol exhibits a linear range of 0.01-100 uM with a detection limit of 0.005 uM at signal to noise ratio of 3. The resulting PEC immunoassay has been proved to be applicable for sensing MNZ in common oral medicine samples.

AB - We investigated the in vitro mitochondria-mediated anticancer and antiproliferative effects of extracts of Annona glabra leafs on human leukemia cells. A. glabra is a tropical tree that exhibits several clinical and pharmacological properties in humans and is effective against cancer. We investigated the antiproliferative effects of an alcoholic extract of A. glabra on MC-1010 human monocytic leukemia cells (crl-12253) based on phytochemical analyses, cell viability, free radical scavenging activity, intracellular reactive oxygen species (ROS) levels, ATP content, mitochondrial fragmentation, and cell migration assays. The results indicated the presence of flavonoids, terpenoids, glycosides, steroids, saponins, tannins, anthraquinones, and acidic compounds in extracts. Leukemia cell viability was reduced up to 28% after incubation with the extract, while the free radical reducing power and scavenging activity were significantly increased. Higher concentrations of extract significantly inhibited leukemia cell colony formation. ROS increased up to 66% following incubation with extract, while the ATP content decreased up to 31%. Condensed, fragmented, and clumped mitochondria were observed in treated cells. In flow cytometric analyses, 10.7% and 22.4% of cells were apoptotic following incubation with 80 and 100 MUg/mL extract, respectively. Moreover, treated leukemia cells exhibited reduced migratory potential. Overall, the results suggest that leaf extracts of A. glabra may act as potential anticancer agents against human leukemia cells. PMID- 30278343 TI - Acid-triggered echogenic nanoparticles for contrast-enhanced ultrasound imaging and therapy of acute liver failure. AB - There has been increasing interest in the development of pathological stimulus activatable nanoplatforms with theranostic functions. Here, we report ketalized maltodextrin (KMD) nanoparticles which are able to deliver therapeutic and imaging functions to the acidic conditions simultaneously, as may be found in the site of inflammation. KMD was synthesized as a platform of the theranostic nanoparticles by conjugating acid-cleavable hydrophobic moieties to maltodextrin through carbonate bonds. KMD nanoparticles could undergo acid-triggered hydrolytic degradation to generate carbon dioxide (CO2) bubbles, amplifying the ultrasound signal. The potential of KMD nanoparticles as a drug carrier was evaluated using silymarin as a model drug. KMD nanoparticles displayed significantly enhanced ultrasound contrast at acidic pH and released drug payloads in acid-triggered manners. The translational potential of silymarin loaded KMD (s-KMD) nanoparticles as ultrasound contrast agents and therapeutic agents was thoroughly evaluated using cell culture models and mouse models of acetaminophen (APAP)-induced acute liver failure. s-KMD nanoparticles exhibited significantly enhanced ultrasound contrast in the APAP-intoxicated liver and also remarkably suppressed the hepatic damages by inhibiting the expression of pro inflammatory cytokines. These results suggest that KMD nanoparticles hold tremendous potential as theranostic agents for various inflammatory diseases. PMID- 30278344 TI - Combinatorial cassettes to systematically evaluate tissue-engineered constructs in recipient mice. AB - Ectopic bone formation in mice is the gold standard for evaluation of osteogenic constructs. By regular procedures, usually only 4 constructs can be accommodated per mouse, limiting screening power. Combinatorial cassettes (combi-cassettes) hold up to 19 small, uniform constructs from the time of surgery, through time in vivo, and subsequent evaluation. Two types of bone tissue engineering constructs were tested in the combi-cassettes: i) a cell-scaffold construct containing primary human bone marrow stromal cells with hydroxyapatite/tricalcium phosphate particles (hBMSCs + HA/TCP) and ii) a growth factor-scaffold construct containing bone morphogenetic protein 2 in a gelatin sponge (BMP2+GS). Measurements of bone formation by histology, bone formation by X-ray microcomputed tomography (MUCT) and gene expression by quantitative polymerase chain reaction (qPCR) showed that constructs in combi-cassettes were similar to those created by regular procedures. Combi-cassettes afford placement of multiple replicates of multiple formulations into the same animal, which enables, for the first time, rigorous statistical assessment of: 1) the variability for a given formulation within an animal (intra-animal variability), 2) differences between different tissue engineered formulations within the same animal and 3) the variability for a given formulation in different animals (inter-animal variability). Combi-cassettes enable a more high-throughput, systematic approach to in vivo studies of tissue engineering constructs.

AB - Over the past two decades, a number of fabrication methods, including 3D printing and bioprinting, have emerged as promising technologies to bioengineer nerve conduits that closely replicate features of the native peripheral nerve, with the aim of augmenting or supplanting autologous nerve grafts. 3D printing and bioprinting offer the added advantage of rapidly creating composite peripheral nerve matrices from micron-scaled units, using an assortment of synthetic, natural and biologic materials. In this review, we explore the evolution of automated 3D manufacturing technologies for the development of peripheral nerve conduits and discuss aspects of conduit design, based on microarchitecture, material selection, cell and protein inclusion, and mechanical properties, as they are adaptable to 3D printing. Additionally, we highlight advancements in the application of bio-imaging modalities toward the fabrication of patient-specific nerve conduits. Lastly, we outline regulatory as well as clinical challenges that must be surmounted for the translation of 3D printing and bioprinting technology to the clinic. As a whole, this review addresses topics that may situate 3D manufacturing at the forefront of fabrication technologies that are exploited for the generation of future revolutionary therapies like in situ printing of peripheral nerves. PMID- 30278346 TI - Tumor microenvironment-targeted poly-L-glutamic acid-based combination conjugate for enhanced triple negative breast cancer treatment. AB - The intrinsic characteristics of the tumor microenvironment (TME), including acidic pH and overexpression of hydrolytic enzymes, offer an exciting opportunity for the rational design of TME-drug delivery systems (DDS). We developed and characterized a pH-responsive biodegradable poly-L-glutamic acid (PGA)-based combination conjugate family with the aim of optimizing anticancer effects. We obtained combination conjugates bearing Doxorubicin (Dox) and aminoglutethimide (AGM) with two Dox loadings and two different hydrazone pH-sensitive linkers that promote the specific release of Dox from the polymeric backbone within the TME. Low Dox loading coupled with a short hydrazone linker yielded optimal effects on primary tumor growth, lung metastasis (~90% reduction), and toxicological profile in a preclinical metastatic triple-negative breast cancer (TNBC) murine model. The use of transcriptomic analysis helped us to identify the molecular mechanisms responsible for such results including a differential immunomodulation and cell death pathways among the conjugates. This data highlights the advantages of targeting the TME, the therapeutic value of polymer-based combination approaches, and the utility of -omics-based analysis to accelerate anticancer DDS. PMID- 30278347 TI - Subcortical SISCOM hyperperfusion: Should we pay more attention to it? AB - PURPOSE: Demonstrating cerebral blood flow changes during seizures, ictal interictal single photon emission computed tomography (SPECT) with co registration to MRI (SISCOM) reflects brain activation and its pathways of spread. To investigate subcortical ictal hyperperfusion patterns during focal seizures, we retrospectively reviewed SISCOM analysis of patients who became seizure-free after cortical resection. Our aim was to evaluate the relationship between epileptogenic zones and subcortical hyperperfusion. METHOD: 67 patients were identified as having SISCOM evaluation and having remained seizure-free for at least one year after surgical resection. SISCOM analysis was blindly reviewed for localization of basal ganglia (BG), thalamic (TN) and cerebellar (CH) hyperperfusion based on three different thresholds. Subcortical activation and epilepsy characteristics were then compared between patients. For a given region of interest and threshold, the sensitivity, specificity and positive and negative predictive value for correct lateralization of the epilepsy side was calculated. RESULTS: Depending on the threshold used, BG hyperperfusion was found in 37.3 73.9% of patients, TN hyperperfusion in 31.3-68.1% and CH hyperperfusion in 13.5 29%. For a threshold of 1.5, the best predictive positive value for correct lateralization of the epilepsy side was obtained with BG/CH coactivation (89%). For a threshold of 2.0 and 2.5, it was obtained with BG/TN coactivation (88%) and BG activation (82%), respectively. CONCLUSION: Subcortical SISCOM hyperperfusion could offer additional clues in terms of lateralization. PMID- 30278348 TI - Short-term and longer-term effects of brivaracetam on cognition and behavior in a naturalistic clinical setting-Preliminary data. AB - PURPOSE: To assess short-term and longer-term effects of brivaracetam (BRV) on cognition and behavior in a naturalistic clinical setting. METHODS: Analyses were based on 43 patients with epilepsy who had undergone a neuropsychological screening before adjunctive treatment with BRV and a follow-up evaluation either after 5 days or 25 weeks. The standard assessment focused on reaction times (Neurocog FX), attention and executive functions (EpiTrack), and verbal memory (short version of the VLMT). Self-perceived cognition and behavior was evaluated by an extended version of the Adverse Events Profile. In addition, health-related quality of life (QOLIE-10) was reassessed at the longer-term interval. RESULTS: Repeated measures analysis of variance revealed a significant improvement under BRV with regard to attention and executive functions (p = .03) without an interaction with the length of the observation interval. A statistical trend in the same direction was also seen for the reaction times (p = .07), but not for the unchanged verbal memory performance. Subjective measures indicated improvements in concentration (p = .02) and especially in comprehension (p < .001), and health-related quality of life (p = .002). Mood and aggression scores were unchanged. At the longer-term follow-up, an at least 50 percent reduction in seizure frequency was observed in 53% of the patients, 21% were seizure free. CONCLUSION: These preliminary data point to a favorable cognitive profile of BRV similar to its precursor levetiracetam. Objective gains in attention and executive functions were accompanied by self-reported improvements in concentration and comprehension. Future studies with larger sample sizes and better control conditions are needed to confirm these findings. PMID- 30278349 TI - Effects of natural and modified calcium-based sorbents on heavy metals of food waste under oxy-fuel combustion. AB - Performance of natural and modified calcium-based sorbents for heavy metals for food waste under oxy-fuel combustion in a lab-scale tubular furnace was carried out. The effects of furnace temperature, sorbents type, and CO2/O2 ratio on adsorption of heavy metals were investigated. Increasing the furnace temperature helped fixing Al in the bottom ash, but increased the volatilization of Zn. The results showed that heavy metals captured by sorbents highly depended on the metals types. Nature and modified CaO had excellent performance for Al capture while CaCO3 could not absorb Al. Neither CaCO3 or CaO could not use as sorbents for the Cr capture. CO2/O2 ratio highly affected the capture of Cr and Zn but had no influence on Al, and the decrease of CO2/O2 ratio would help capturing Cr and Zn. This work contributes to the heavy metals controlled by Ca-based sorbents during municipal solid waste oxy-fuel combustion. PMID- 30278350 TI - Impact of carbon to nitrogen ratio on the performance of aerobic granular reactor and microbial population dynamics during aerobic sludge granulation. AB - Carbon to nitrogen (C/N) ratio is one of the most important factor affecting aerobic granular sludge (AGS) growth and pollutant removal in aerobic granular sludge sequencing batch reactor (AGSBR). For stability of sludge granulation process, AGSs were domesticated in five sequence batch reactors (SBRs) with different C/N ratios (6, 7, 8, 9, and 10), which the ammonia nitrogen concentration of influent was 165 mg/L. The effects of C/N ratio on morphology and property of AGS were studied. The results showed that stable AGS was yielded with good settleability, high pollutant removal efficiency and rich microbial diversity when C/N ratio was 8. AGS yielded had stable structure due to higher protein in extracellular polymeric substances (EPS). High throughput 16S rDNA gene analysis revealed the microbial community diversity increased in AGS under the C/N ratio. The dominant microbes changed at the phylum, class and family three levels with the increasing operation time. PMID- 30278351 TI - Metabolic engineering of Clostridium tyrobutyricum for enhanced butyric acid production from undetoxified corncob acid hydrolysate. AB - Resistance to furan derivatives and phenolic compounds plays an important role in the use of lignocellulosic biomass for biological production of chemicals and fuels. This study confirmed that expression of short-chain dehydrogenase/reductase (SDR) from Clostridium beijerinckii NCIMB 8052 significantly improved the tolerance of C. tyrobutyricum to furfural due to the enhanced activity for furfural reduction. And on this basis, co-expression of SDR and heat shock chaperones GroESL could simultaneously enhance the tolerance of C. tyrobutyricum to furan derivatives and phenolic compounds, which were the main inhibitors presented in dilute-acid lignocellulosic hydrolysates. Consequently, the recombinant strain ATCC 25755/sdr+groESL exhibited good performance in butyric acid production with corncob acid hydrolysate as the substrate. Batch fermentation in bioreactor showed that the butyrate produced by ATCC 25755/sdr+groESL was 32.8 g/L, increased by 28.1% as compared with the wild-type strain. Meanwhile, the butyrate productivity increased from 0.19 g/L.h to 0.29 g/L.h. PMID- 30278352 TI - Improved biobleaching of mixed hardwood pulp and process optimization using novel GA-ANN and GA-ANFIS hybrid statistical tools. AB - The process parameters for xylanase biobleaching of mixed hardwood pulp like, reaction time (6-35 h), pulp consistency (2.5-15%) and xylanase dose (5-35 U) were optimized using OFAT approach and hybrid statistical tools viz. GA-ANN and GA-ANFIS. The biobleaching ability of xylanase in terms of reducing sugar yield increased up to 28.16 mg g-1 (28.05%) than OFAT optimization (21.99 mg g-1 of pulp) after employing hybrid statistical tools. After TCF bleaching of xylanase treated pulp, we observed that lignin content reduced to 0.29% whereas it was still 0.41% in the untreated pulp. Moreover, the brightness level achieved up to 70.4% in xylanase treated pulp while it was only 53.60% in the chemically treated pulp. The kappa number for xylanase treated, chemically treated, and xylanase chemical treated pulp was recorded 9.90, 7.10 and 4.70, respectively. The present study reports an improved eco-friendly biobleaching method using novel GA-ANN and GA-ANFIS hybrid statistical tools. PMID- 30278353 TI - Methods for tentative determination of presence of artificial nuclides in air using NuRMS EGS air sampler and WIMP 120 gross alpha/beta counter. AB - The determination of the presence of artificial radionuclides in the air is mainly accomplished by using gamma spectrometry analysis of filter samples. This work suggests very fast, reliable and efficient methods for tentative quantitative determination of the activity of artificial nuclides such as transuranic elements, strontium, yttrium, etc. in the air based only on the gross alpha and beta volume activity. The main aspect of these methods is to provide information about approximate results for the gross alpha and beta activity of air filters, thus it is convenient as a triage technique. Unlike gamma spectrometry, the methods are not qualitative but it allows the preliminary estimation of the presence of non-natural radionuclides. The influence of increment of the dust layer on self-absorption of alpha/beta particles was also studied. The methods are particularly suitable for screening situations where radionuclide identification is not necessary. PMID- 30278355 TI - A novel transcription factor Rwdd1 and its SUMOylation inhibit the expression of sqr, a key gene of mitochondrial sulfide metabolism in Urechis unicinctus. AB - Sulfide-quinone oxidoreductase (SQR) is a key enzyme of sulfide metabolism in metazoans, and responsible for oxidizing sulfide into thiosulfate and transmitting the generated electrons to the ubiquinone. It has been revealed that the sqr mRNA level increases significantly in echiuran worm Urechis unicinctus exposed to sulfide, and HSF1, NF1 and Sp1 have been verified to participate in its transcriptional regulation. In this study, we obtained 23 potential transcription factors interacting possibly with the proximal region (-391 to +50) of sqr promoter, and focused on the RWD domain-containing 1 (Rwdd1), a protein with the maximum number of clones in yeast one-hybrid (Y1H) screening, to investigate its transcriptional regulation to U. unincitus sqr. The ChIP and EMSA assays identified that the Rwdd1 can bind directly to the promoter (+18/+36) of U. unicinctus sqr. The point mutation and transient transfection experiments discovered that TACG was the key sequence of the DNA element bound by the Rwdd1. Furthermore, the U. unicinctus Rwdd1 (UuRwdd1) was identified to be a transcription repressor inhibiting the sqr promoter activity, and the SUMOylation of UuRwdd1 at the lysine of 90th enhanced its inhibitory effect on sqr transcription further. Western blotting found Rwdd1 responded to sulfide in hindguts from U. unincitus, and the protein content showed a remarkable drop in hindgut nuclei in the early sulfide exposure, and then increased significantly both in the total protein and the nuclear protein extract. We suggested that the Rwdd1 is a novel transcription factor, and these data improve our understanding of the sqr transcriptional regulation and the mitochondrial sulfide metabolism. PMID- 30278356 TI - CETP inhibition, statins and diabetes. AB - Type 2 diabetes is a causal risk factor for the development of atherosclerotic cardiovascular disease (ASCVD). While treatment with a statin reduces the risk of having an ASCVD event in all people, including those with type-2 diabetes, statin treatment also increases the likelihood of new onset diabetes when given to those with risk factors for developing diabetes. Treatment with the cholesteryl ester transfer protein (CETP) inhibitor, anacetrapib, reduces the risk of having a coronary event over and above that achieved with a statin. However, unlike statins, anacetrapib decreases the risk of developing diabetes. If the reduced risk of new-onset diabetes is confirmed in another CETP inhibitor outcome trial, there will be a case for considering the use of the combination of a statin plus a CETP inhibitor in high ASCVD-risk people who are also at increased risk of developing diabetes. PMID- 30278354 TI - Effects of ocean warming and acidification on accumulation and cellular responsiveness to cadmium in mussels Mytilus galloprovincialis: Importance of the seasonal status. AB - Ocean warming and acidification could represent an additional threat to marine organisms already coping with other anthropogenic impacts, such as chemical contamination in coastal areas. In this study, interactions between such multiple stressors and their synergistic effects in terms of accumulation, detoxification and biological effects of metals were investigated in the Mediterranean mussel Mytilus galloprovincialis. Organisms sampled during the winter period were exposed for 28 days to different combinations of two temperatures (10 degrees C and 15 degrees C), two pH/pCO2 (8.20/~400MUatm and 7.4/~3000MUatm) and two cadmium concentrations (0 and 20 MUg/L). Cadmium concentrations increased in digestive glands and gills of metal-exposed mussels and were further enhanced by co-exposure at higher temperature. Interactive effects of temperature and/or pH were observed on Cd-mediated metallothionein induction, responsiveness of antioxidant system and onset of oxidative damages in lipids, with tissue-specific effects. Immunological effects showed a generalized sensitivity of lysosomal membrane stability toward the investigated stressors with major effects in co exposed organisms. Cadmium and temperature affected phagocytosis efficiency and composition of haemocyte populations probably influencing the micronucleus frequency through varied mitotic rate. Several differences were highlighted between these results and those previously obtained from mussels exposed in summer, supporting the importance of season when addressing the tolerance of temperate organisms to variations of environmental factors. The elaboration of the whole biomarker results through weighted criteria allowed to summarize specific hazard indices, highlighting tissue-specific sensitivity toward multiple stressors and the need of improving the knowledge on interactions between multiple stressors. PMID- 30278357 TI - Increased electronegativity of high-density lipoprotein in uremia patients impairs its functional properties and is associated with the risk of coronary artery disease. AB - BACKGROUND AND AIMS: Uremia patients have impaired high-density lipoprotein (HDL) function and a high risk of coronary artery disease (CAD). Increased lipoprotein electronegativity can compromise lipoprotein function, but the effect of increased HDL electronegativity on HDL function and its association with CAD in uremia patient are not clear. We aimed to assess HDL electronegativity and various properties of HDL in uremia patients and investigate whether electronegative HDL is a risk factor for CAD in these individuals. METHODS: HDL from 60 uremia patients and 43 healthy controls was separated into 5 subfractions (H1H5) with increasing electronegativity by using anion-exchange chromatography. Lipoprotein content was analyzed by gel electrophoresis and matrix-assisted laser desorption/ionization time-of-flight-mass spectrometry. HDL anti-oxidant, anti apoptosis and cholesterol efflux activities were examined by fluorescence-based assays. RESULTS: The percentage of H5 HDL (H5%) was significantly higher in uremia patients than in controls (p < 0.001). The concentration of apolipoprotein (Apo) AI was lower and apolipoprotein modifications were more prevalent in uremia HDL subfractions than in control HDL subfractions. Carbamylation of ApoAI and ApoCIII was increased in more electronegative HDL subfractions from uremia patients. Anti-oxidant activity, anti-apoptotic activity, and cholesterol efflux capability were reduced in HDL subfractions from uremia patients when compared with control HDL subfractions. Multiple logistic regression analysis showed that H5% was associated with CAD risk in uremia patients. CONCLUSIONS: In HDL of uremia patients, increased electronegativity is accompanied by compositional changes and impaired function. Our findings indicate that increased H5% is associated with increased CAD risk in uremia patients. PMID- 30278358 TI - Cold shock Y-box binding protein-1 acetylation status in monocytes is associated with systemic inflammation and vascular damage. AB - BACKGROUND AND AIMS: In dialysis patients, vascular morbidities are highly prevalent and linked to leukocyte extravasation, especially of polarized monocytes. Experimental data demonstrate that phenotypic changes in monocytes require Y-box binding protein-1 (YB-1) upregulation. METHODS: We determined YB-1 expression in circulating and vessel-invading monocytes from healthy controls and dialysis patients to correlate results with intima plaque formation and systemic inflammation. RESULTS: Compared to healthy subjects, dialysis patients have fewer classical and more intermediate and non-classical monocytes. Post-translationally modified YB-1 (lysine 301/304 acetylation) is detected at high levels in the nucleus of adherent and invading CD14+CD68+ monocytes from umbilical cord and atherosclerosis-prone vessels. The content of non-acetylated YB-1 is significantly decreased (p < 0.001), whereas acetylated YB-1 is correspondingly increased (p < 0.001) throughout all monocyte subpopulations, such that the overall content remains unchanged. CONCLUSIONS: In dialysis patients the YB-1 acetylation status is higher with prevailing diabetes and intima plaque formation. Pro-inflammatory mediators TNFalpha, IL-6, uPAR, CCL2, M-CSF, progranulin, ANP, and midkine, as well as anti-inflammatory IL-10 are significantly increased in dialysis patients, emphasizing a systemic inflammatory milieu. Strong positive correlations of monocytic YB-1 content are seen with ANP, IP-10, IL-6, and IL-10 serum levels. This is the first study demonstrating an association of cold shock protein YB-1 expression with inflammation in hemodialysis patients. PMID- 30278359 TI - Gender differences in the association of syndecan-4 with myocardial infarction: The population-based Tromso Study. AB - BACKGROUND AND AIMS: Cardiovascular disease is a common cause of morbidity and mortality, with gender differences in pathophysiology. The endothelial glycocalyx maintains vascular integrity, and glycocalyx shedding reflects endothelial dysfunction and early atherosclerosis. Syndecan-1 and -4 are components of the glycocalyx, and increased serum levels indicate glycocalyx damage. We hypothesised that increased serum syndecan-1 and -4 were independently associated with myocardial infarction (MI), ischaemic stroke and all-cause mortality in men and women from a general population. METHODS: Using a case-cohort design, we included 1495 participants from the Tromso Study 2001-02. Syndecan-1 and -4 were measured in serum. Baseline variables also included age, gender, cardiovascular risk factors and urinary albumin-creatinine ratio (ACR). Hazard ratios were assessed using multivariable Cox regression models. RESULTS: Between baseline in 2001-02 and December 2007 fatal or non-fatal MI was experienced by 328 and ischaemic stroke by 191 subjects, and 423 participants died. Syndecan-4 was independently associated with MI (hazard ratio per 10 ng/mL increase 1.32; 95% confidence interval 1.06-1.63), but not ischaemic stroke and mortality, and the associations were unchanged by adjustment for urinary ACR. Interaction between syndecan-4 and sex was borderline significant, and in gender-specific analysis, syndecan-4 was associated with MI in women only. Syndecan-1 was not associated with any endpoint. CONCLUSIONS: Syndecan-4 was associated with incident MI, and the association was stronger in women than in men. This suggests a link between endothelial glycocalyx shedding and coronary heart disease in women. Use of syndecan-4 as a risk marker in clinical setting needs further investigation. PMID- 30278360 TI - Nucleation and growth of pores in 1,2-Dimyristoyl-sn-glycero-3-phosphocholine (DMPC) / cholesterol bilayer by antimicrobial peptides melittin, its mutants and cecropin P1. AB - Antimicrobial peptides are one of the most promising alternatives to antibiotics for targeting pathogens without developing resistance. In this study, pore formation in 1,2-Dimyristoyl-snglycero-3-phosphocholine (DMPC) / cholesterol liposome induced by native melittin, its two mutant variants (G1I and I17 K), and cecropin P1 was investigated by monitoring the dynamics of fluorescence dye leakage. A critical peptide concentration was required for dye leakage with the rate of leakage being dependent on peptide concentration above a critical value. A lag time was required for dye leakage for low peptide concentrations that are above the critical value, which decreased at higher peptide concentrations eventually approaching zero. Lag time was found to be in the order I17 K mutant with lower hydrophobicity and higher net charge > G1I with higher hydrophobicity > melittin > cecropin P1. Cecropin P1 exhibited the highest rate of dye leakage followed by melittin, G1I, and I17 K. Size distribution and transmission electron microscopy (TEM) of liposomes exposed to peptides of different concentrations indicated pore formation with accompanied stretching of liposomes at low peptide concentrations for both melittin and cecropin P1. At much higher concentrations, however, size distribution indicated three peaks for both peptides. In both cases, TEM images show that the middle and small peaks are shown to be due to stretched liposome and broken stretched liposome respectively. For melittin, the large peak is due to peptide aggregates as well as aggregates of liposome. For cecropin P1, however, the large peak indicates cecropin P1 aggregates with solubilized lipids thus suggesting carpet mechanism. PMID- 30278361 TI - Investigation of the structural conformation and surface interaction of desired chimeric hydrophobin: Interface simulation via molecular dynamics. AB - Hydrophobins are small amphiphilic fungal proteins that are highly surface-active and are used in various industrial applications such as dispersion, immobilization, and antifouling. At hydrophobic-hydrophilic interfaces, hydrophobins tend to self-assemble as rodlets or monolayers, depending on whether they are class I or II. Several studies have determined the three-dimensional structure and investigated the self-assembly formation mechanism of the class I EAS from Neurospora crassa and the class II HFBII from Trichoderma reesei. Although some studies have examined the performance of chimeric hydrophobins, they have not been investigated at the atomic scale. Here, we designed chimeric hydrophobins by grafting the L1 loop of Vmh2 and the L3 loop of EAS onto the class II hydrophobin HFBII by homology modeling and performed vacuum-water interface molecular simulations to determine their structural behaviors. We found that the chimeric hydrophobin grafted with the L3 of EAS became unstable under standard conditions, whereas that grafted with the L1 of Vmh2 became unstable in the presence of calcium ions. Moreover, when both the EAS L3 and Vmh2 L1 were grafted together, the structure became disordered and lost its amphiphilic characteristics in standard conditions. In the presence of calcium, however, its structural stability was restored. However, an additional external perturbation is required to trigger the conformational transition. Although our chimeric hydrophobin models were designed through homology modeling, our results provide detailed information regarding hydrophobin self-assembly and their surface interactive behavior that may serve as a template for designing hydrophobins for future industrial applications. PMID- 30278362 TI - Extracellular electron transfer of Bacillus cereus biofilm and its effect on the corrosion behaviour of 316L stainless steel. AB - Here, a heterogeneous Bacillus cereus (B. cereus) biofilm on the surface of 316 L stainless steel (SS) was observed. With electrochemical measurement and surface analysis, it was found that B. cereus biofilm could inhibit SS pitting corrosion, attributing to the blocking effect of bacterial biofilm on extracellular electron transfer (EET). Differential pulse voltammetry (DPV) and cyclic voltammetry (CV) results also showed that B. cereus biofilm clearly impeded the EET. The proposed mechanism for the decreased corrosion rates of SS involves the interactions of extracellular polymeric substance (EPS) with SS and biofilm formation blocking electron transfer, preventing the passive layer from destroying. After biofilm formation following initial attachment of cells and EPS, electron transfer between SS and the cathodic depolarizer (oxygen) was hindered. PMID- 30278363 TI - Human health risks due to exposure to inorganic and organic chemicals from textiles: A review. AB - It is well known that a number of substances used in the textile industry can mean not only environmental, but also health problems. The scientific literature regarding potential adverse health effects of chemical substances in that industry is mainly related with human exposure during textile production. However, information about exposure of consumers is much more limited. Although most research on the health effects of chemicals in textiles concern allergic skin reactions, contact allergy is not the only potential human health problem. In this paper, we have reviewed the current scientific information regarding human exposure to chemicals through skin-contact clothes. The review has been focused mainly on those chemicals whose probabilities of being detected in clothes were rather higher. Thus, we have revised the presence of flame retardants, trace elements, aromatic amines, quinoline, bisphenols, benzothiazoles/benzotriazoles, phthalates, formaldehyde, and also metal nanoparticles. Human dermal exposure to potentially toxic chemicals through skin contact textiles/clothes shows a non-negligible presence in some textiles, which might lead to potential systemic risks. Under specific circumstances of exposure, the presence of some chemicals might mean non-assumable cancer risks for the consumers.

AB - BACKGROUND: Studies have examined the variation in mortality risk associated with ambient ozone. We conducted an international cooperation study for investigating the non-linear ozone-mortality association accounting for lag effect and for examining the ozone level with significant health effect. METHODS: Daily counts of total non-accidental death and ambient air pollutant concentration were obtained in 17 cities from 3 Eastern Asian countries or regions (Taiwan, Korea, and Japan). The total study period was from 1979 to 2010 and differed by city based on data availability. The ozone-mortality association in each city was estimated by running a time-series quasi-Poisson regression model, allowing for overdispersion. The city-specific estimates were then pooled by country by using multivariate random effects meta-analysis. RESULTS: The non-linear ozone exposure mortality response curves were generated in 17 cities from Taiwan, Korea, and Japan. The association curves in the three countries all showed increased mortality with elevated ozone, and the significant mortality effects of ozone exposure were observed at level higher than 40, 50, and 40 ppb for Taiwan, Korea, and Japan, respectively. These associations are unaffected by co-pollutant of particulate matter in Taiwan and Japan. But the potential confounding effect of co-pollutant could not be ignorable in Korea. CONCLUSIONS: Our study provides evidence that exposure to a relative low level of ambient ozone is associated with an increased risk of mortality. Our results emphasize the continual need to examine the existing standard by documenting potential human adverse effects. PMID- 30278364 TI - Self-reported myocardial infarction and fatal coronary heart disease among oil spill workers and community members 5 years after Deepwater Horizon. AB - BACKGROUND: Chemical, physical and psychological stressors due to the 2010 Deepwater Horizon oil spill may impact coronary heart disease (CHD) among exposed populations. Using longitudinal information from two interviews in the Gulf Long Term Follow-up (GuLF) STUDY, we assessed CHD among oil spill workers and community members. OBJECTIVE: To assess the associations between duration of oil spill clean-up work, residential proximity to the oil spill, and incidence of self-reported myocardial infarction or fatal CHD. METHODS: Among respondents with two GuLF STUDY interviews (n = 21,256), there were 395 first incident heart disease events (self-reported myocardial infarction or fatal CHD) across 5 years. We estimated hazard ratios (HR) and 95% confidence intervals (95%CI) for associations with duration of oil spill clean-up work and residential proximity to the oil spill. To assess potential impacts of non-response, we compared covariate distributions for those who did (n = 21,256) and did not (n = 10,353) complete the second interview and used inverse probability (IP) of censoring weights to correct for potential non-response bias. RESULTS: Living in proximity to the oil spill (vs. living further away) was associated with heart disease, with [HR(95%CI) = 1.30(1.01-1.67)] and without [1.29(1.00-1.65)] censoring weights. For work duration, hazard of heart disease appeared to be higher for those who worked > 180 days (vs. 1-30 days), with and without censoring weights [1.43(0.91-2.25) and 1.36(0.88-2.11), respectively]. Associations persisted throughout the 5-year follow-up. CONCLUSIONS: Residential proximity to the spill and duration of clean-up work were associated with a suggested 29-43% higher hazard of heart disease events. Associations were robust to censoring.

AB - Copper oxide (CuO) nanomaterials (NMs) of different size and morphology were synthesized by Chemical precipitation, Microwave irradiation and Hydrothermal method and characterized by TEM, BET, FTIR, XRD and EDX analysis. As synthesized CuO NMs were utilized for elimination of harmful dyes viz. Direct Red 81 (DR-81) and Coomassie Brilliant blue R-250 (BBR-250) and pathogenic bacteria (Staphylococcus aureus). Owing to their morphology, smaller size and relatively high surface area (40.320 m2 g-1), CuO NMs prepared by chemical precipitation method were observed to show better adsorption capacity for both the dyes (68.70 (DR-81) and 73.04 (BBR-250) mg g-1). The influence of different experimental conditions was studied by the methodical assessments of various parameters such as pH, adsorbent dose, concentration and contact time. Moreover, different adsorption isotherms and pseudo-second order kinetic model were applied to understand the adsorption mechanism. Langmuir model was found to be best fit thus confirming the monolayer adsorption process. To ensure the practical utility of CuO NMs for organic waste removal, the adsorption studies were performed in the presence of different inorganic ions and real water samples. In addition, recovery of the dye and NMs were also carried out effectively by simple method, thus avoiding the secondary pollution. CuO NMs were observed to exhibit significant antibacterial activity against the human pathogenic bacteria. These studies demonstrated that synthesized CuO NMs showed good adsorption efficiency for the removal of harmful dyes and antimicrobial activity against the pathogenic bacteria, which vary as a function of size and surface area.

PMID- 30278368 TI - Is the occiput-wall distance valid and reliable to determine the presence of thoracic hyperkyphosis? AB - BACKGROUND: Hyperkyphosis may be frequently found nowadays due to the change in current lifestyles of sustained flexion postures and age-related system decline. The occiput-wall distance (OWD) is a practical measure that is commonly used to screen and monitor thoracic hyperkyphosis in epidemiologic studies. However, there was no clear evidence to support the clinical utility of the tool as compared to the data from direct standard measures. OBJECTIVES: To investigate psychometric properties-including validity, reliability, and appropriate cut-off point-of the OWD to determine the presence of thoracic hyperkyphosis, as compared to a standard Cobb's method. DESIGN: Observational study. METHODS: This study was conducted in ninety-nine participants, aged 10 years and above who had different degrees of thoracic hyperkyphosis from several communities. All participants were assessed for their severity of thoracic hyperkyphosis using the OWD, and 14 participants were involved in a reliability study. Within 7 days later, all participants were at a hospital to complete a radiographic examination. RESULTS: Outcomes from OWD had good concurrent validity with the Cobb angles (r = 0.683, P < 0.001) and excellent rater reliability when assessed by well-trained health professionals (ICCs > 0.9, P < 0.001). The OWD of at least 6.5 cm had the best diagnostic properties to determine the presence of thoracic hyperkyphosis (sensitivity = 71.4%, specificity = 76.6%, and area under the curve = 0.846). CONCLUSION: The findings support validity and reliability of OWD, and offer a clear cut-off point to determine the presence of thoracic hyperkyphosis for clinical utility in various settings. PMID- 30278370 TI - The effect of sulfur dioxide addition at crush on the fungal and bacterial communities and the sensory attributes of Pinot gris wines. AB - Modern day winemaking often involves the addition of sulfur dioxide (SO2) at crush to act as both an antioxidant and an antimicrobial agent. While the effects of SO2 on microbial communities and particularly on spoilage microorganisms has been well-studied, the advent of culture-independent molecular technologies, such as Illumina sequencing, allows the subject to be re-visited in a new context. High-throughput amplicon sequencing allows for a more thorough evaluation of microbial communities, as thousands of microbial sequences per sample can be identified and even rare microorganisms can be studied. This research investigated whether the addition of different levels of SO2 at crush (0, 20, or 40 mg/L) would affect the composition of fungal and bacterial communities, as well as the sensory attributes of the resulting wines. Samples were taken from uninoculated fermentations of Pinot gris and analyzed via high-throughput amplicon sequencing using the Illumina MiSeq platform. Yeast relative abundance and overall fungal community composition differed among the SO2 additions. Notably, a Hanseniaspora yeast appeared in all treatments and persisted until the end of alcoholic fermentation, although its relative abundance was significantly higher in the fermentations to which low or no SO2 had been added. Two key wine sensory attributes (citrus aroma and pome fruit flavor) differed among the SO2 treatments. This research provides an in-depth look into the fungal and bacterial communities during alcoholic fermentation and gives a better understanding of the microbial community response to SO2 additions during the crush period. PMID- 30278369 TI - The presentation, management and outcome of inflammatory breast cancer cases in the UK: Data from a multi-centre retrospective review. AB - OBJECTIVES: Inflammatory Breast cancer (IBC) is a rare but aggressive form of breast cancer. Its incidence and behaviour in the UK is poorly characterised. We collected retrospective data from hospitals in the UK and Ireland to describe the presentation, pathology, treatment and clinical course of IBC in the UK. MATERIALS AND METHODS: Patients with IBC diagnosed between 1997-2014 at fourteen UK and Irish hospitals were identified from local breast unit databases. Patient characteristics, tumour pathology and stage, and details of surgical, systemic and radiotherapy treatment and follow-up data were collected from electronic patient records and medical notes. RESULT: This retrospective review identified 445 patients with IBC accounting for 0.4-1.8% of invasive breast cancer cases. Median follow-up was 4.2 years. 53.2% of tumours were grade 3, 56.2% were oestrogen receptor positive, 31.3% were HER2 positive and 25.1% were triple negative. 20.7% of patients had distant metastases at presentation. Despite trimodality treatment in 86.4%, 40.1% of stage III patients developed distant metastases. Five-year overall survival (OS) was 61.0% for stage III and 21.4% for stage IV patients. CONCLUSIONS: This is the largest series of UK IBC patients reported to date. It indicates a lower incidence than in American series, but confirms that IBC has a high risk of recurrence with poor survival despite contemporary multi-modality therapy. A national strategy is required to facilitate translational research into this aggressive disease. PMID- 30278371 TI - Is impaired information processing speed a matter of structural or functional damage in MS? AB - OBJECTIVE: Cognitive deficits, especially those of information processing speed (IPS), are common in multiple sclerosis (MS), however, the underlying neurobiological mechanisms remain poorly understood. In this study, we examined structural and functional brain changes separately, but also in an integrative manner, in relation to IPS performance. METHODS: IPS was measured using the symbol digit modalities test (SDMT) in 330 MS patients and 96 controls. Patients with IPS impairment (IPS-I, z-score < -1.5) were compared to patients with preserved IPS performance (IPS-P) on volumetric measures, white matter integrity loss (using diffusion tensor imaging) and the severity of functional connectivity changes (using resting-state fMRI). Significant predictors of IPS performance were used to create groups of mild or severe structural and/or functional damage to determine the relative effect of structural and/or functional changes on IPS. RESULTS: IPS-I patients, compared to IPS-P patients, showed lower deep gray matter volume and less WM integrity, but stronger increases in functional connectivity. Patients with predominantly structural damage had worse IPS (z score = -1.49) than patients with predominantly functional changes (z-score = 0.84), although both structural and functional measures remained significant in a regression model. Patients with severe structural and functional changes had worst IPS (z-score = -1.95). CONCLUSION: The level of structural damage explains IPS performance better than functional changes. After integrating functional and structural changes, however, we were able to detect more subtle and stepwise decline in IPS. In subgroups with a similar degree of structural damage, more severe functional changes resulted in worse IPS scores than those with only mild functional changes. PMID- 30278372 TI - Voxel-wise deviations from healthy aging for the detection of region-specific atrophy. AB - The identification of pathological atrophy in MRI scans requires specialized training, which is scarce outside dedicated centers. We sought to investigate the clinical usefulness of computer-generated representations of local grey matter (GM) loss or increased volume of cerebral fluids (CSF) as normalized deviations (z-scores) from healthy aging to either aid human visual readings or directly detect pathological atrophy. Two experienced neuroradiologists rated atrophy in 30 patients with Alzheimer's disease (AD), 30 patients with frontotemporal dementia (FTD), 30 with dementia due to Lewy-body disease (LBD) and 30 healthy controls (HC) on a three-point scale in 10 anatomical regions as reference gold standard. Seven raters, varying in their experience with MRI diagnostics rated all cases on the same scale once with and once without computer-generated volume deviation maps that were overlaid on anatomical slices. In addition, we investigated the predictive value of the computer generated deviation maps on their own for the detection of atrophy as identified by the gold standard raters. Inter and intra-rater agreements of the two gold standard raters were substantial (Cohen's kappa kappa > 0.62). The intra-rater agreement of the other raters ranged from fair (kappa = 0.37) to substantial (kappa = 0.72) and improved on average by 0.13 (0.57 < kappa < 0.87) when volume deviation maps were displayed. The seven other raters showed good agreement with the gold standard in regions including the hippocampus but agreement was substantially lower in e.g. the parietal cortex and did not improve with the display of atrophy scores. Rating speed increased over the course of the study and irrespective of the presentation of voxel-wise deviations. Automatically detected large deviations of local volume were consistently associated with gold standard atrophy reading as shown by an area under the receiver operator characteristic of up to 0.95 for the hippocampus region. When applying these test characteristics to prevalences typically found in a memory clinic, we observed a positive or negative predictive value close to or above 0.9 in the hippocampus for almost all of the expected cases. The volume deviation maps derived from CSF volume increase were generally better in detecting atrophy. Our study demonstrates an agreement of visual ratings among non-experts not further increased by displaying, region-specific deviations of volume. The high predictive value of computer generated local deviations independent from human interaction and the consistent advantages of CSF-over GM based estimations should be considered in the development of diagnostic tools and indicate clinical utility well beyond aiding visual assessments. PMID- 30278374 TI - Rapid and efficient differentiation of functional motor neurons from human iPSC for neural injury modelling. AB - Primary rodent neurons and immortalised cell lines have overwhelmingly been used for in vitro studies of traumatic injury to peripheral and central neurons, but have some limitations of physiological accuracy. Motor neurons (MN) derived from human induced pluripotent stem cells (iPSCs) enable the generation of cell models with features relevant to human physiology. To facilitate this, it is desirable that MN protocols both rapidly and efficiently differentiate human iPSCs into electrophysiologically active MNs. In this study, we present a simple, rapid protocol for differentiation of human iPSCs into functional spinal (lower) MNs, involving only adherent culture and use of small molecules for directed differentiation, with the ultimate aim of rapid production of electrophysiologically functional cells for short-term neural injury experiments. We show successful differentiation in two unrelated iPSC lines, by quantifying neural-specific marker expression, and by evaluating cell functionality at different maturation stages by calcium imaging and patch clamping. Differentiated neurons were shown to be electrophysiologically altered by uniaxial mechanical deformation. Spontaneous network activity decreased with applied stretch, indicating aberrant network connectivity. These results demonstrate the feasibility of this rapid, simple protocol for differentiating iPSC-derived MNs, suitable for in vitro neural injury studies focussing on electrophysiological alterations caused by mechanical deformation or trauma. PMID- 30278373 TI - Structural covariance networks relate to the severity of epilepsy with focal onset seizures. AB - PURPOSE: The brains of patients with epilepsy may exhibit various morphological abnormalities, which are often not directly visible on structural MR images, as they may be focally subtle or related to a more large-scale inconspicuous disorganization of brain structures. To explore the relation between structural brain organization and epilepsy characteristics, including severity and cognitive co-morbidity, we determined structural covariance networks (SCNs). SCNs represent interregional correlations of morphologic measures, for instance in terms of cortical thickness, between various large-scale distributed brain regions. METHODS: Thirty-eight patients with focal seizures of all subtypes and 21 healthy controls underwent structural MRI, neurological, and IQ assessment. Cortical thickness was derived from the structural MRIs using FreeSurfer. Subsequently, SCNs were constructed on a group-level based on correlations of the cortical thicknesses between various brain regions. Individual SCNs for the epilepsy patients were extracted by adding the respective patient to the control group prior to the SCN construction (i.e. add-one-patient approach). Calculated network measures, i.e. path length, clustering coefficient and betweenness centrality were correlated with characteristics related to the severity of epilepsy, including seizure history and age at onset of epilepsy, and cognitive performance. RESULTS: Stronger clustering in the individual SCN was associated with a higher number of focal to bilateral tonic-clonic seizures during life time, a younger age at onset, and lower cognitive performance. The path length of the individual SCN was not related to the severity of epilepsy or cognitive performance. Higher betweenness centrality of the left cuneus and lower betweenness centrality of the right rostral middle frontal gyrus were associated with increased drug load and younger age at onset, respectively. CONCLUSIONS: These results indicate that the correlations between interregional variations of cortical thickness reflect disease characteristics or responses to the disease and deficits in patients with epilepsy with focal seizures. PMID- 30278375 TI - Viral-free generation and characterization of a human induced pluripotent stem cell line from dermal fibroblasts. AB - Peripheral dermal fibroblasts (DF) from a healthy 56 year old female were obtained from the Centre for Healthy Brain Ageing (CHeBA) Biobank, University of New South Wales, under the material transfer agreement with the University of Wollongong. DFs were reprogrammed via mRNA-delivered transcription factors into induced pluripotent stem cells (iPSCs). The generated iPSCs were confirmed to be pluripotent, capable of three germ layer differentiation and are thus a useful resource for creating iPSC-derived healthy human cells of any lineage.

AB - The human GLI3 protein has a dual function as a transcriptional activator or repressor of hedgehog signaling, depending on the proteolytic processing forms of GLI3. In this study, we established a compound heterozygous GLI3 mutant human embryonic stem cell line (WAe001-A-20) through CRISPR/Cas9 editing. The WAe001-A 20 cells carried two deletions on two different alleles of exon 2 of GLI3, respectively, which resulted in a frame shift and early termination in the translation of GLI3. Moreover, WAe001-A-20 maintains a normal karyotype, parental cell morphology, pluripotent phenotype and the ability to differentiate into three germ layers. Resource table. PMID- 30278377 TI - A comprehensive analysis of gestational trophoblastic neoplasia trials posted at online clinical trial registries. AB - OBJECTIVE: We conducted a comprehensive analysis of gestational trophoblastic neoplasia (GTN) trials posted at online registries and aimed to provide useful information for future GTN trial designs. STUDY DESIGN: We searched ClinicalTrials.gov, EU Clinical Trials Register, WHO International Clinical Trials Registry Portal (ICTRP) Search Portal, Australian New Zealand Clinical Trial Registry, ISRCTN Register, and Chinese Clinical Trial Register for all the clinical trials reporting GTN treatments. The general information of each trial was extracted. RESULTS: Twenty trials meeting the inclusion criteria were included in the final analysis. In total, 6 trials were phase II trials, 2 were phase II/III trials, 7 were phase III trials, and 1 was a phase IV trial; and the phase type of 4 trials were not reported. The conditions included low-risk GTN (n = 15), high-risk GTN (n = 2), and mixed GTN (n = 3). Randomization was performed in 15 trials, and the remaining 5 trials were single-arm trials. The median enrollment size for randomized clinical trials (RCTs) and single-arm trials was 80 and 38, respectively. Among the RCTs, parallel assignment was used in 12 trials, crossover assignment was used in 1, and the intervention models of 2 were not reported. For masking, 15 trials were open-label, 2 were single-blinded, 2 were double-blinded, and the masking status of 1 was not reported. Ovarian functions and pregnancy outcome after chemotherapy were evaluated in only 2 trials. Regarding sponsorship, 2 trials had industry sponsorship. CONCLUSION: Conducting RCTs for GTN is challenging, and international collaboration and smarter clinical trial designs are required for future GTN trials. PMID- 30278379 TI - A study on collaborative telepsychiatric consultations to outpatients of district hospitals of Karnataka, India. AB - INTRODUCTION: The Indian National Mental Health Survey (NMHS) of 2015-2016 has estimated 13.7% lifetime and 10.6% point prevalence for mental illnesses. It has identified that the treatment gap for mental illnesses ranges between 70% and 92%. Tele-Psychiatric consultations could be an alternative and innovative approach to bridge this gap in low resource settings. AIMS: To study the sociodemographic and clinical profiles of patients who have received collaborative Tele-Psychiatric consultations across district hospitals in Karnataka, India. METHODOLOGY: We performed a retrospective review of case files of patients who have received collaborative Tele-Psychiatric consultations from January 2013 to June 2017 through video-conferencing. A total of 139 consultations were provided to patients in the state of Karnataka. RESULTS: The mean age of the sample is 31 (+/-15.5) years. 61.8% were male and 79.8% were aged more than 18 years. In total, 25.9% of them had schizophrenia and other psychotic disorders, 14.4% had mental retardation, 13.7% had a mood disorder and 14.4% had a substance use disorder. 67.6% of patients had been advised pharmacotherapy, 7.9% had been advised rehabilitation along with pharmacotherapy and 24.4% were advised further evaluation of illness and inpatient care at a higher centre. CONCLUSION: Collaborative tele-psychiatric consultations to district hospitals from an academic tertiary care hospital can be feasible and are likely to benefit patients from rural areas. There is a need for more studies to elucidate their acceptability by patients, caregivers and professionals. PMID- 30278378 TI - A phase 1b study of afatinib in combination with standard-dose cetuximab in patients with advanced solid tumours. AB - This phase 1b, open-label trial assessed the combination of afatinib, an ErbB family blocker, with cetuximab, an epidermal growth factor receptor (EGFR) monoclonal antibody, in heavily pretreated patients with unselected/EGFR wild type, advanced solid tumours. In Part A, the maximum tolerated dose (MTD) of afatinib + cetuximab was evaluated using a 3 + 3 dose-escalation design; the starting dose was afatinib 30 mg/day plus cetuximab 250 mg/m2/week (after cetuximab 400 mg/m2 loading dose), escalating to afatinib 40 mg/day. Part B further evaluated safety and tolerability at the MTD and preliminary anti-tumour activity in three patient cohorts with squamous non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC) and other solid tumours. Nine patients were treated in Part A; the MTD and recommended dose was determined as afatinib 40 mg/day plus cetuximab 250 mg/m2/week. In Part B, 49 patients were treated at the recommended dose (12 with squamous NSCLC, 15 with HNSCC and 22 with other tumours). The most common treatment-related adverse events (AEs) across all 58 patients were diarrhoea (63.8%) and acneiform dermatitis (43.1%). Overall, the best confirmed response was stable disease (SD; 53.4%); mean duration of disease control was 4.5 months; median progression-free survival was 2.6 months. In Part B, 55.1% of patients had SD (squamous NSCLC, 75.0%; HNSCC, 66.7%; other tumours; 36.4%). In conclusion, the recommended phase 2 dose was determined as afatinib 40 mg/day plus cetuximab 250 mg/m2/week. AEs were predictable and manageable, and anti-tumour activity was observed in some patients, particularly in those with squamous NSCLC and HNSCC. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT02020577. PMID- 30278380 TI - Understanding the potential for selective natural organic matter removal by ion exchange. AB - Dissolved organic carbon (DOC) removal from a river water source was investigated using ion exchange (IEX), coagulation and membrane filtration. This research linked the variable charge characteristics of the organic compounds present in the source water with removal by IEX and coagulation. The raw water charge density fluctuated considerably (between 5.4 and 10.7 meq mgDOC-1) and controlled removal of the charge loading. Importantly, charge density was not correlated with the organic carbon concentration. The combined IEX and coagulation process reduced the specific DBP-FP (sDBP-FP) of the final water, with values as low as 18 MUg mgDOC-1 for both haloacetic acids and trihalomethanes. IEX removed a particular fraction of NOM that 1) enhanced coagulation efficiency, providing increased removal of overall DOC; and 2) enabled coagulation to subsequently remove higher levels of specific components of NOM that have a high DBP-FP. The component of NOM removed by IEX that had a positive impact on coagulation was identified to be charged low molecular weight organic compounds of all hydrophobicity levels, resulting in a reduced specific DBP-FP compared to coagulation alone. PMID- 30278381 TI - Effects of Escherichia coli and phosphate on the transport of titanium dioxide nanoparticles in heterogeneous porous media. AB - Transport behaviors of titanium dioxide nanoparticles (nTiO2) were examined in the individual- and co-presence Escherichia (E.) coli and phosphate in heterogeneous sand (uncoated and iron oxyhydroxide-coated sand) columns. The results showed that for the individual presence of phosphate, the degree of nTiO2 deposition was less in uncoated than in iron oxide-coated sands. In contrast, an opposite trend that greater deposition of nTiO2 in uncoated than in coated sands occurred in the individual presence of E. coli. These observations are due to the phosphate adsorption changing the charge of NPs and iron oxyhydroxide-coated sand, or the preferential adhesion of bacterial to coated sand. In the copresence of E. coli and phosphate, interestingly, the phosphate level plays an important role in influencing nTiO2 transport. At a high phosphate concentration (>1.0 mM), the deposition of nTiO2 with the individual presence of E. coli was stronger than nTiO2 in the copresence of both E. coli and phosphate, regardless of sand type. The potential mechanism was that phosphate adsorption led to the formation of more negatively charged NPs-bacteria complexes that have higher mobility in sand columns. At a low phosphate level (<=0.1 mM), a similar observation occurred in uncoated sand. Nevertheless, the deposition of nTiO2 with copresence of E. coli and phosphate was greater than nTiO2 with E. coli in oxyhydroxide-coated sand. It was attributed to the formation of large NPs-bacteria-phosphate clusters (less mobile) and the preferential adhesion of E. coli cells to iron oxyhydroxide coating simultaneously. Taken together, our findings provide crucial knowledge for better understanding the fate, transport, and potential risks of engineered nanoparticles in complicated environmental settings where bacteria and phosphate are ubiquitous. PMID- 30278382 TI - Inhibitory effects of ammonia on syntrophic propionate oxidation in anaerobic digester sludge. AB - Syntrophic propionate oxidation (SPO) coupled with methanogenesis is often inhibited under high ammonium concentrations in anaerobic digesters. However, the inhibitory mechanism remains poorly understood. We conducted two independent laboratory experiments with a swine manure digester sludge. In experiment I, RNA based stable isotope probing (SIP) was applied to determine the active players of both bacteria and methanogens involved in SPO under different ammonium concentrations (0, 3 and 7 g NH4+N L-1). In experiment II, the dynamics of the bacterial community under ammonia stress was monitored using the 16S rRNA pyrosequencing and quantitative PCR under similar conditions as in experiment I but without the addition of external propionate. An additional higher ammonium treatment (10 g NH4+N L-1) was applied in experiment II to maximize the ammonia stress. We identified that the Smithella bacteria and the Methanosaetaceae and Methanospirillaceae archaea were the most active players involved in SPO and methanogenesis. We revealed that Smithella, Methanosaetaceae and Methanospirillaceae were moderately and severely inhibited at 3 and 7-10 g NH4+N L-1, respectively. However, the fermentative bacteria appeared to be more tolerant to ammonia stress. The microbial responses were corroborated with the accumulation of VFAs and the repression of methanogenesis under high ammonium conditions. PMID- 30278383 TI - Fc-gamma receptor IIA and IIIA variants in two African cohorts: Lack of consistent impact on heterosexual HIV acquisition, viral control, and disease progression. AB - Human Fc-gamma receptors (FcgammaRs) FcgammaRIIA and FcgammaRIIIA contain amino acid variants with both high and low affinities for IgG that modulate antibody mediated effector functions. Recent HIV vaccine trials suggested that these FcgammaR variants can influence susceptibility to HIV infection, which prompted us to fully assess the role of FcgammaR variants on HIV acquisition, viral control, and disease progression in two longitudinal heterosexual transmission cohorts with HIV subtypes A and C as the major circulating viruses. For 836 participants, molecular genotyping resolved genetic variations encoding the FcgammaRIIA (131 H/R) and FcgammaRIIIA (158 V/F) single nucleotide polymorphisms. Kaplan-Meier curves, Cox proportional hazards models, and linear regression models did not reveal any clear or consistent FcgammaR association with time to HIV acquisition, viral load in early infection, or extent of CD4 + T-cell decline over time after infection. Overall, previous epidemiological findings on FcgammaR variants and vaccine efficacy are not readily applicable to heterosexual HIV transmission. PMID- 30278384 TI - Broad-spectrum antiviral JL122 blocks infection and inhibits transmission of aquatic rhabdoviruses. AB - The aquaculture industry is growing rapidly to meet the needs for global protein consumption. Viral diseases in aquaculture are quite challenging due to lack of treatment options as well as limited injection-delivery vaccines, which are costly. Thus, water-immersion antiviral treatments are highly desirable. This study focused on broad-spectrum, light-activated antivirals that target the viral membrane (envelope) of viruses to prevent viral-cell membrane fusion, ultimately blocking viral entry into cells. Of the tested small-molecules, JL122, a new broad-spectrum antiviral previously unexplored against aquatic viruses, blocked infection of three aquatic rhabdoviruses (IHNV, VHSV and SVCV) in cell culture and in two live fish challenge models. Importantly, JL122 inhibited transmission of IHNV from infected to uninfected rainbow trout. Further, the effective antiviral concentrations were not toxic to cells or susceptible fish. These results show promise for JL122 to become an immersion treatment option for outbreaks of aquatic enveloped viral infections. PMID- 30278385 TI - Comparison of postmortem butane distribution between two fatal butane poisoning cases. AB - Fatal accidents during butane abuse frequently occur in Japan and in many countries around the world. Although analytical data about butane concentration in postmortem samples is being accumulated, when using the data to determine the cause of death, careful interpretation is required because the gas is easily diffused. Two fatal butane poisoning cases were encountered, and butane quantification of autopsy samples obtained from left and right heart blood, femoral blood, kidney, liver, lung, brain and fatty tissues was performed. In both cases, butane concentration in the left heart blood was lower than in the right heart blood or the femoral blood, despite gas inhalation. These findings may indicate that the deceased individuals interrupted gas inhalation and inhaled room air immediately before their death, therefore ruling out asphyxia due to anoxia as the mechanism of death. Case 1, which was suspected to be a not acute death, showed a very high butane concentration ratio of fatty tissues to femoral blood of over 70. Case 2 was considered an acute death, and the butane concentration ratio of fatty tissues to femoral blood was 8.2. These results are consistent with previously reported findings showing that much higher ratios of fatty tissues to blood are compatible with long survival time. In conclusion, the comparison of butane concentration among different samples, including left heart blood versus right heart blood and fatty tissues versus blood, is useful when interpreting the result of postmortem butane analysis to examine the mechanism of death and survival time. PMID- 30278386 TI - Two loci concurrent mutations in non-exclusion parentage cases using 19 STR profiles. AB - Two loci concurrent mutations in non-exclusion paternity case were reported based on 19 STR loci available from GoldeneyeTM DNA ID System 20A (Peoplespot, Beijing, China). When 9508 family trios with Paternity index (PI) threshold of >10,000 was analyzed, 14 families show mutations at two loci. The paternity was confirmed by using an additional 19 STR markers. When the probability of occurrence of two mutations was compared with the expected probability deduced from binomial model, the observed mutational probability was significantly larger than the expectation. However, the characteristics of mutations agree with those reported previously. Our result indicates that larger samples is still need to estimate mutation rates accurately and reveal the relationship between mutations with multiple loci and the characterization of human mutations based on microsatellites.

AB - OBJECTIVE: We propose an electrooculogram and submandibular montage that helps to discriminate eye/eyelid/tongue movements and to differentiate them from epileptiform activity or slowing on electroencephalography (EEG). METHODS: We analyzed different eye/eyelid and tongue movements in 6 and 4 patients, respectively. Six peri-orbitally and one submandibular electrodes were placed. We referred these electrodes to an indifferent reference (Cz/Pz) and we recorded eye/eyelid and tongue movements simultaneously with the 10-20 system EEG. Additionally, we analyzed 2 seizures with the electrooculogram montage. RESULTS: The electrooculogram deflections always showed an opposite phase direction when eye/eyelid movements occurred. Conversely, epileptiform activity produced deflections in the same phase direction in all electrooculogram electrodes. The electrooculogram montage was able to distinguish eye ictal semiology. Vertical tongue movements showed opposite phase deflections between the submandibular and the inferior ocular electrodes. Horizontal tongue movements revealed opposite phase reversal deflections between both inferior ocular electrodes. CONCLUSIONS: The proposed montage accurately defines different eye/eyelid and tongue movements from brainwave activity. Additionally, it is useful to differentiate eye/eyelid movements from epileptiform activity and to characterize ictal ocular semiology, which can help localize or lateralize the epileptogenic zone. SIGNIFICANCE: We propose this new montage to provide added value to prolonged video-EEG studies. PMID- 30278388 TI - Impaired performance of patients with writer's cramp in complex fine motor tasks. AB - OBJECTIVE: Writer's cramp (WC) is a task-specific focal dystonia. WC is characterized by involuntary contractions of muscles of the hand and arm during handwriting, resulting in impaired writing with exaggerated finger forces. The generalization of symptoms to other fine motor tasks is widely discussed. The aim of the study was to determine affected fine motor aspects with an extensive testing battery. METHODS: Twelve people with WC and twelve healthy controls were examined. Performance in the Jebsen-Taylor Hand Function Test, Nine-Hole-Peg Test and 2-point discrimination was evaluated. To analyze object manipulation skills, we examined grip forces, temporal measures and other aspects of force control during (1) lifting actions with variations of weight and surface (2) cyclic movements (3) visuomotor tracking (4) fast force changes and (5) grip strength. In addition, correlation between the dependent variables of the fine motor tasks and the handwriting deficits was assessed. RESULTS: WC patients had impaired performance in the visuomotor tracking task (root mean square error (RMSE), p = 0.03 and time lag, p = 0.05) and the fast force changes (frequency, p = 0.01). There were no statistically significant group differences in the other tasks. We found a correlation between the RMSE of the tracking task and the time needed to write the test sentence (r = 0.643, p = 0.01). CONCLUSION: WC patients revealed abnormalities in complex fine motor performance in tasks with high demands on coordination and visual components, specifically in tracking and fast force changes. SIGNIFICANCE: This suggests a deficit in visuomotor integration, coordination and cognitive aspects related to movement processing particularly with respect to low forces. These insights may prove useful in the development of targeted training approaches. PMID- 30278389 TI - Automated EEG source imaging: A retrospective, blinded clinical validation study. AB - OBJECTIVE: To evaluate the accuracy of automated EEG source imaging (ESI) in localizing epileptogenic zone. METHODS: Long-term EEG, recorded with the standard 25-electrode array of the IFCN, from 41 consecutive patients with focal epilepsy who underwent resective surgery, were analyzed blinded to the surgical outcome. The automated analysis comprised spike-detection, clustering and source imaging at the half-rising time and at the peak of each spike-cluster, using individual head-models with six tissue-layers and a distributed source model (sLORETA). The fully automated approach presented ESI of the cluster with the highest number of spikes, at the half-rising time. In addition, a physician involved in the presurgical evaluation of the patients, evaluated the automated ESI results (up to four clusters per patient) in clinical context and selected the dominant cluster and the analysis time-point (semi-automated approach). The reference standard was location of the resected area and outcome one year after operation. RESULTS: Accuracy was 61% (95% CI: 45-76%) for the fully automated approach and 78% (95% CI: 62-89%) for the semi-automated approach. CONCLUSION: Automated ESI has an accuracy similar to previously reported neuroimaging methods. SIGNIFICANCE: Automated ESI will contribute to increased utilization of source imaging in the presurgical evaluation of patients with epilepsy. PMID- 30278390 TI - Atypical perceptual and neural processing of emotional prosodic changes in children with autism spectrum disorders. AB - OBJECTIVE: The present study explored the processing of emotional speech prosody in school-aged children with autism spectrum disorders (ASD) but without marked language impairments (children with ASD [no LI]). METHODS: The mismatch negativity (MMN)/the late discriminative negativity (LDN), reflecting pre attentive auditory discrimination processes, and the P3a, indexing involuntary orienting to attention-catching changes, were recorded to natural word stimuli uttered with different emotional connotations (neutral, sad, scornful and commanding). Perceptual prosody discrimination was addressed with a behavioral sound-discrimination test. RESULTS: Overall, children with ASD (no LI) were slower in behaviorally discriminating prosodic features of speech stimuli than typically developed control children. Further, smaller standard-stimulus event related potentials (ERPs) and MMN/LDNs were found in children with ASD (no LI) than in controls. In addition, the amplitude of the P3a was diminished and differentially distributed on the scalp in children with ASD (no LI) than in control children. CONCLUSIONS: Processing of words and changes in emotional speech prosody is impaired at various levels of information processing in school aged children with ASD (no LI). SIGNIFICANCE: The results suggest that low-level speech sound discrimination and orienting deficits might contribute to emotional speech prosody processing impairments observed in ASD. PMID- 30278391 TI - Cognitive load of walking in people who are blind: Subjective and objective measures for assessment. AB - BACKGROUND: Although walking without vision seems to carry a high cognitive cost, few studies have measured the cognitive load involved in this activity in blind people. The aim of this study was to assess the cognitive load of walking in blind people, using gait analysis, a dual task paradigm and a subjective assessment of cognitive load. METHODS: In a quantitative quasi-experimental design, 25 blind adults walked 40 meters. In one trial, participants walked normally (control condition). In another, they walked while performing an auditory simple reaction time task, and in the third trial they walked, performed the simple reaction time task and avoided obstacles. In addition to the simple reaction time task performance, walking speed was recorded, and participants provided a subjective assessment of cognitive load after each trial. Performance of participants aged less than 60 years were compared with those aged over than 60 years. RESULTS: Walking significantly reduced performance of the simple reaction time task; carrying out the simple reaction time task while walking significantly reduced walking performance and increased the subjective assessment of cognitive load; and simple reaction time task performance decreased and subjective assessment increased when obstacles were present. Few significant age effects were found. SIGNIFICANCE: Walking without vision involves a cognitive load that increases when the environment becomes complex. Each of the three methods used is relevant when assessing the cognitive load involved in walking in blind people, and could be useful in rehabilitation intervention. The results obtained allowed recommendations to be suggested for the design of technological mobility devices. PMID- 30278392 TI - Microcystin and pyriproxyfen are toxic to early stages of development in Rhamdia quelen: An experimental and modelling study. AB - The recent increase of freshwater eutrophication has favored cyanobacteria blooms and consequently the increase of toxins such as microcystin-LR in aquatic environments, but few is know about the associated effect of toxin and other compounds. Pyriproxyfen is an insecticide indicated by WHO (World Health Organization) to control Aedes aegypti mosquito (vector of Dengue, Chikungunya and Zika diseases), however, the effects are not well described to non-target species, such as fish. The early life stages (ELS) of fish are more sensitive to chemical stress due to higher metabolic rate, immature immune system and high superficial area/volume ratio. In the current study, ELS of R. quelen a Neotropical fish were exposed to environmentally realistic concentrations of microcystin (1, 10 and 100 ug L-1; M1, M2 and M3 groups, respectively) from an algal extract, pyriproxyfen (1 and 10 ug L-1, P1 and P2) and their association (co-exposure). The hatching, survival and larvae deformities were analyzed, and applied a mathematical model to evaluate the effects on the population size along further generations. Both compounds were toxic to embryos/larvae of fish, but the effects were more pronounced in M2, P1M2 and P2M1 for hatching and M2, P1M2, P2M1 and P1 for survival. Deformities prevailed in groups exposed to the chemicals at 48 hpf (hours post-fertilization) were suggestions of toxicological interaction in P1M2, P2M1 and P2M2 at 48 and 72 hpf. In 96 hpf, the levels of deformities were lower than in previous times. Model predicted population density over 100 years decreased to lower than 0.5 (50%) in all groups, except for P1M1, indicating risk of extinction. P1M2 had the worse results, followed by M2, P1M3 and P2M1. Cyanobacterial blooms can lead to microcystin-LR levels higher than M2 (10 ug L-1), and the suggestion of toxicological interaction with pyriproxyfen is relevant because both compounds may potentially coexist in aquatic environments. Finally, mathematical models may provide an ecological interpretation of the risk of exposure of fish. PMID- 30278393 TI - Occurrence, distribution and risk assessment of pesticides in a river-reservoir system. AB - The water environment from river to reservoir has been considered as a hybrid river-reservoir system due to pronounced environmental properties. This study investigated the distribution and potential environmental behavior of pesticides in river-reservoir system, examining 31 target pesticides in water phase from a key drinking water source (Dongjiang River). The concentrations of ?8OCPs, ?16OPPs and ?7SPs with the corresponding occurrence were in the range of 107.57 340.35 ng/L (moderate level), 232.65-1197.95 ng/L (moderate level) and 125.23 245.09 ng/L (low level), respectively. Ecological risk assessments indicated that most of the pesticides posed a high level of risk to the aquatic organisms. Moreover, seasonal agricultural application, rainfall and temperature could influence the levels and compositions of ?8OCPs, ?16OPPs and ?7SPs in the river system, while seasonal hydrological processes could only influence their compositions in the reservoir system. In the wet season, the levels of ?8OCPs and ?7SPs decreased from the river system to reservoir system probably via biogeochemical processes, while the level of ?16OPPs decreased along the environmental gradient probably via dilution process. Additionally, longer hydraulic retention time of the reservoir system could contribute to the biogeochemical processes for OPPs and SPs exported from the river system, but it might fail to facilitate this process for OCPs. Taken together, this study highlighted that the distributions and environmental behavior of pesticides in river-reservoir system varied seasonally from river system to reservoir system. PMID- 30278394 TI - Response of soil enzymes, functional bacterial groups, and microbial communities exposed to sudan I-IV. AB - As an important type of typical synthetic azo dyes, the use of sudan I-IV dyes has been of concern worldwide because of their wide applications and illegal addition into various foodstuffs, potentially resulting in water and soil pollution and having adverse effects on human health and ecosystems. However, to date, little has been reported regarding the environmental levels of these dyes and the risks that they pose to human health and ecosystems. Understanding the responses of soil enzymes, functional groups of bacteria and microbial communities to sudan dyes is of great importance to reveal their effect on the soil environment. In this study, we performed a toxicological study on the specific and overall effects of sudan I-IV dyes on the activity of soil enzymes including catalase, urease, and alkaline phosphatase after a 2- and 7-day exposure, functional groups of soil bacteria including nitrogen-fixing, ammonia oxidizing, and denitrifying bacteria on day 14, and the structure and diversity of soil microbial community compositions on day 30. The results showed that sudan I-IV affected the activity of the soil enzymes, the abundance of the bacterium functional groups, and the structure and diversity of microbial community compositions, and the effects varied by sudan dyes I-IV, the exposure concentration, and the exposure time. PMID- 30278395 TI - Impairment of learning and memory of mice offspring at puberty, young adulthood, and adulthood by low-dose Cd exposure during pregnancy and lactation via GABAAR alpha5 and delta subunits. AB - Cadmium (Cd) is a pervasive carcinogen and environmental endocrine disruptor. We studied the changes in learning and memory of offspring mice, whose mothers were exposed to 10 mg Cd/L via the drinking water during pregnancy and lactation period, as well as the changes of testosterone and estrogen levels, serum Cd levels, the histopathological changes and the changes in the mRNA and protein levels of different subunits of gamma-aminobutyric acid receptor subtype A subunits (GABAARs) in the hippocampus at the prepuberty, puberty, young adult, and adult stages. At birth, Cd had no obvious effect on mice offspring as statistically accessed based on their body weight, body length, and tail length (all p > 0.05). After grouped, the serum Cd levels increased in the three exposed groups more than in the normal control group at stages (all p < 0.05). Only serum estradiol of female offspring at age 7 weeks was significantly decreased compared with other groups (all p < 0.05). Histopathological results showed that the arrangement of the cells in hippocampal CA1 area of mice offspring was significantly sparse in the exposed groups compared with the control group. At 5 and 7 weeks, two Cd-exposed groups showed prolonged escape latency and exploring time for the platform compared with the normal group in the Morris water maze (all p < 0.05). Only increased protein expression of GABAARalpha5 was found in the Cd group at these two ages. At age 12 weeks, similar impaired learning and memory of female mice, and decreased protein expression of GABAARdelta was found in Cd-exposed groups. Collectively, low-dose Cd had no effect on the growth of mice offspring but affected their learning and memory, especially female offspring, at puberty, young adulthood, and adulthood through changed structure in the hippocampal CA1 area and protein expression of GABAARalpha5 and GABAARdelta. PMID- 30278396 TI - Distribution, pollution, bioaccumulation, and ecological risks of trace elements in soils of the northeastern Qinghai-Tibet Plateau. AB - Environmental quality of the northeastern Qinghai-Tibet Plateau has attracted more attention due to increasing anthropogenic disturbance. Therefore, this study investigated the distribution, pollution, ecological risks, and bioaccumulation of 12 target heavy metals and 16 rare earth elements (REEs) in soils of this area. The average concentrations of target trace elements in soils ranged from 0.16 (Hg) to 500.46 (Cr) mg/kg. Pb caused more serious pollution than the other elements based on geo-accumulation index evaluation. Hg exhibited the strongest enrichment feature with the average enrichment factor of 8.41. Compare with modified contamination degree and pollution load index, Nemerow pollution index method obtained the most serious evaluation results that 45.67% and 16.54% of sampling sites possessed high and moderate pollution. Evaluation results of potential ecological risk index showed that trace elements in soils posed very high and considerable ecological risks in 34.65% and 7.09% of sampling sites, respectively. Mining area was the region with the most serious pollution and ecological risks. Average bioaccumulation factor (BCF) values of target trace elements ranged from 0.05 (REEs) to 2.67 (Cr). Cr was the element that was easier to bio-accumulate in plants of the study area than the other target elements. It is in urgent need to take effective measures for controlling current pollution and potential ecological risks of trace elements in soils of the northeastern Qinghai-Tibet Plateau. PMID- 30278397 TI - Assessing mercury pollution in Amazon River tributaries using a Bayesian Network approach. AB - Mercury pollution of water bodies exerts significant human and ecosystem health impacts due to high toxicity. Relatively high levels of mercury have been detected in the Amazon River and its tributaries and associated lakes. The study employed a Bayesian Network approach to investigate the contribution from geogenic sources to mercury pollution of lakes in the Madeira River basin, which is the largest tributary of the Amazon River. It was found that the source indicators of naturally occurring mercury have both, positive and negative relationships with mercury in lake sediments. Although the positive relationships indicated the influence of geological and soil formations, the negative relationships implied that the use of mercury amalgam for gold extraction in artisanal and small-scale mining (ASM), which is the primary anthropogenic source of mercury, also contribute to mercury in Amazon tributaries. This was further evident as mercury concentrations in lake sediments were found to be significantly higher than those in the surrounding rocks. However, potential anthropogenic mercury was attributed to historical inputs from gold mining due to the recent decline of ASM mining practice in the region. PMID- 30278398 TI - Sub-lethal UV radiation during early life stages alters the behaviour, heart rate and oxidative stress parameters in zebrafish (Danio rerio). AB - Environmental UV radiation in sufficient doses, as a possible consequence of climate change, is potent enough to affect living organisms with different outcomes, depending on the exposure life stage. The aim of this project was to evaluate the potentially toxic effects of exposure to sub-lethal and environmentally relevant doses of UVA (9.4, 18. 7, 37.7 J/cm2) and UVB radiation (0.013, 0.025, 0.076 J/cm2) on the development and behaviour in early life stages (4.5-5.5 h post fertilization, hpf) of the zebrafish (Danio rerio). The used doses were all below the median lethal dose (LD50) and caused no significant difference in survival, deformities, or hatching between exposed and control groups. Compared to controls, there were transient UVA and UVB exposure effects on heart rate, with dose dependent reductions at 50 hpf, and at 60 hpf for UVA only. The UVB exposure caused an increasing trend in reactive oxygen species (ROS) formation at the two highest doses, even though only significant at 120 hpf for the second highest dose. Both UVA and UVB caused an increasing trend in lipid peroxidation (LPO) at the highest doses tested at 72 hpf. Furthermore, UVA exposure led to significant reductions in larval movement following exposure to the two highest doses of UVA, i.e., reduction in the time spent active and the total distance moved compared to control at 100 hpf, while no effect on the swimming speed was observed. The lowest dose of UVA had no effect on behaviour. In contrast, the highest dose of UVB led to a possible increase in the time spent active and a slower average swimming speed although these effects were not significant (p = 0.07). The obtained results show that UV doses below LD50 levels are able to cause changes in the behaviour and physiological parameters of zebrafish larvae, as well as oxidative stress in the form of ROS formation and LPO. Further testing is necessary to assess how this type of radiation and the effects observed could affect fish population dynamics. PMID- 30278399 TI - Land use impact on potentially toxic metals concentration on surface water and resistant microorganisms in watersheds. AB - Soil and water resources must be conserved and protected. However, the management of production activities causes a change in the quality of these natural resources due to accumulation in soil of potentially toxic metals. The objective of the present study was to identify the variety and paths of potentially toxic metals (PTMs), such as cadmium, lead, copper, chromium, nickel and zinc, which are associated spatially and temporally to soil and water. We also intended to isolate bacteria resistant to PTMs with important characteristics to be used in bioremediation processes. Water samples were collected every two months for one year (February-December/2014) at eight sites (P1-P8) and the soil samples were collected twice (February and August/2014) from twelve sites (S1-S12). Results indicated that agricultural land use impacts the environment, increasing the concentration of potentially toxic metals, mainly copper, zinc and chromium, in soil and water due to crop management. Ten bacteria resistant to all the metals studied were isolated, which could be used as tools for bioremediation of contaminated soils and water with those metals. The results would positively contribute to land use policy, and for the development of enhanced agricultural practices. PMID- 30278400 TI - Capacity of tissue water regulation is impaired in an osmoconformer living in impacted estuaries? AB - Estuarine osmoconformes rely on their ability to perform tissue and cell water regulation to cope with daily osmotic challenges that occur in the estuary. In addition, these animals currently must deal with pollutants present in the estuarine environment, which can disturb their capacity of water regulation. We collected the mangrove oyster Crassostrea rhizophorae in two tropical estuaries in the Northeast region of Brazil with different degrees of human interference: the Paraiba Estuary (impacted) and the Mamanguape Estuary (preserved). Tissue water content was analyzed after exposure to salinities 12, 24 and 36 for 24 h. Gill cell volume regulation was analyzed in vitro upon hypo- and hyper-osmotic conditions. We also analyzed gill MXR (multi-xenobiotic resistance) mechanism, as reference of environmental pollution. Gill and muscle of oysters from two sites of Paraiba Estuary, and from one site of Mamanguape Estuary were not able to maintain tissue water content upon hypo- and hyper-osmotic conditions. Gill cells of oyster from the same sites exhibited swelling followed by regulatory volume decrease upon hypo-osmotic condition. Gill MXR activity was increased in oysters from these sites. The best tissue and cell water regulation, and the lowest MXR activity, was found in oyster from downstream of Mamanguape Estuary, our reference site and the one most preserved. Tissue and cell water regulation proved to be a sensitive parameter to environmental pollution and could be considered as biomarker of aquatic contamination. PMID- 30278401 TI - Effects of softwood biochar on the status of nitrogen species and elements of potential toxicity in soils. AB - The effects of softwood-derived biochar materials on the chemical behaviour of environmental contaminants in soils were examined in two microcosm scenarios. Addition of the biochar materials into an alkaline sandy soil significantly reduced NH3 volatilization and made it available for conversion into NO3- via nitrification. This process could be enhanced by an increased application rate of biochar produced at a higher pyrolysis temperature. Under the alkaline conditions encountered in the experiment, the biochar surfaces tended to be negatively charged which disfavours the adsorption of NO3-. Therefore, in a fully open system, the addition of biochar materials was likely to contribute to nitrate leaching from the fertilized alkaline sandy soil. The effects of the biochar materials on the immobilization of Fe2+ generated via anaerobic iron reduction in the inundated contaminated soil were not observed, except for the treatment with a higher dose of biochar material produced under pyrolysis temperature at 700 degrees C after the 240th h of incubation. Arsenic showed similar behaviour to Fe. Zn tended to have a higher affinity to the biochar, as compared to Mn. Immobilization of Pb occurred regardless of whether or not the biochar is present. PMID- 30278402 TI - Environmental hazard and risk assessment of thiochemicals. Application of integrated testing and intelligent assessment strategies (ITS) to fulfil the REACH requirements for aquatic toxicity. AB - REACH requires information on hazardous properties of substances to be generated avoiding animal testing where possible. It is the objective of the present case study with thiochemicals to extract as much information as possible from available experimental data with fish, daphnia and algae and to fill data gaps for analogues to be registered under REACH in 2018. Based on considerations of chemical similarity and common mode of action (MOA) the data gaps regarding the aquatic toxicity of the thiochemicals were largely closed by trend analysis ("category approach") and read-across within the same group, for example, thioglycolates or mercaptopropionates. Among 16 thiochemicals to be registered by 2018 there are only 2 substances with sufficient data. 36 data gaps for 14 thiochemicals were identified. Most of the required data (>60%) could be estimated by in silico methods. Only 14 tests (6 algae, 6 daphnia, 1 limit fish test and 1 acute fish test) were proposed. When the results of these tests are available it has to be discussed whether 2 further fish (limit) tests are required. For two substances (exposure-based) waiving was suggested. The relatively high toxicity of the thiochemicals is manifested in low predicted no effect concentrations (PNECs). Only preliminary predicted environmental concentrations (PECs) could be derived for the thiochemicals for which a risk assessment has to be performed (production rate >10 t/y). The preliminary PEC/PNEC ratios indicate no risk for the aquatic compartment at the production site. PECs due to down-stream use must not exceed the estimated PNECs. PMID- 30278403 TI - A review of the implications and challenges of manganese removal from mine drainage. AB - Manganese (Mn) is the third most abundant transition metal in the Earth's crust. Decades of increasing worldwide mining activities have inevitably led to the release of large amounts of this metal into the environment. Mine drainage, either acidic or neutral, often contains high levels of Mn, which have potentially detrimental effects on ecosystems and receiving water bodies. This review provides a comprehensive assessment of the main implications and challenges of Mn treatment in mine drainage. With this aim, the beneficial and adverse effects of Mn on ecosystems and human health are presented first. A comparison of background and mine effluents Mn contents is also provided, further stressing the need for Mn removal from mine drainage. Several technical options to address Mn contamination in acid and neutral mine drainage, and the challenges associated with Mn removal, are subsequently discussed. Thus, this paper presents up-to-date knowledge on the available physicochemical and biological processes deemed operative in Mn removal during mine drainage treatment and their limitations considering the distinctive behavior of Mn. The discussion is further extended to passive treatment systems, which are the most commonly implemented systems for mine drainage treatment on abandoned or closed mine sites, and highlights both their design criteria and operation requirements, as well as the factors that influence Mn removal efficiency. Finally, new perspectives on future research and development needs are identified to address the challenges in Mn removal during mine drainage treatment. PMID- 30278404 TI - Multiple biomarkers based appraisal of deltamethrin induced toxicity in silver carp (Hypophthalmichthys molitrix). AB - Deltamethrin (DLM) is alpha-cyano (type II) synthetic pyrethroid. DLM exposure leads to strong neurotoxic effects and a number of complex toxicological syndromes. The current study assessed DLM mediated oxidative stress, behavioral, hematological, histopathological, and biochemical toxic effects on silver carp (Hypophthalmichthys molitrix). Exposure to an acute concentration (2 MUg/L) of DLM resulted in different behavioral inconsistencies and a time-dependent significant (P < 0.05) change in the hematology and serum biochemistry of silver carp. A significant (P < 0.05) increase in the activities of reactive oxygen species, lipid peroxidation, and antioxidant enzymes whereas a significant decrease in total protein contents in the liver, gills, brain, and muscle tissues were observed. DLM exposure increased the activities of metabolic enzymes in the gills, muscles, and liver of silver carp. A significant (P < 0.05) increase in DNA damage in peripheral blood erythrocytes was evident. DLM exposure led to a time-dependent significant (P < 0.05) increase in the whole-body cortisol and blood glucose level, while a significant decrease in acetylcholine esterase activity in the brain, liver, and muscle tissues. Different histopathological changes in the liver, gills, brain, and intestine were observed, however, no significant change in the gross anatomy and morphometric parameters of the fish was observed. The current study provides valuable information for devising better strategies regarding environmental management, chemicals' risk assessment, biodiversity conservation, and monitoring of the aquatic organisms. DLM was concluded to be highly toxic to fish. The extensive use of DLM should be prohibited or allowed under strict environmental laws; otherwise, it might lead to the extermination of the susceptible wildlife, such as commercially very valuable but nearly threatened silver carp. PMID- 30278405 TI - A mixture of Persistent Organic Pollutants (POPs) and Azoxymethane (AOM) show potential synergistic effects on intestinal tumorigenesis in the A/J Min/+ mouse model. AB - A multitude of cancer types, including breast, testicular, liver and colorectal cancer, have associations with exposure to Persistent Organic Pollutants (POPs). The present study aimed to investigate whether a mixture of POPs could affect intestinal tumorigenesis in the A/J Min/+ mouse, a model for human colorectal cancer (CRC). Pollutants were selected for their presence in Scandinavian food products and the mixture was designed based on defined human estimated daily intake levels. Mice were exposed through the diet, at control, low and high mixture concentrations, for 10 weeks. In a separate experiment, mice also received one subcutaneous injection of Azoxymethane (AOM) to explore whether this carcinogenic compound influenced the effect of the POPs. Intestinal tumorigenesis was examined by surface microscopy and histopathology. Moderate and dose dependent increases in tumorigenesis were observed after dietary POP exposure. The AOM treatment alone stimulated the growth of colonic lesions, but did not increase the formation of new lesions. Combined AOM treatment and POP exposure demonstrated a synergistic effect on lesion formation in the colon, and to a lesser extent in the small intestine. This synergy was also evident by an increased number of malignant colonic tumors (carcinomas). In conclusion, the study shows that a mixture of POPs interacted synergistically with a known carcinogen (AOM), causing increased intestinal tumorigenesis in the A/J Min/+ mouse model. PMID- 30278406 TI - The role of electrical impedance tomography for monitoring during bronchoscopy: A case report. AB - Continuous monitoring of lung ventilation can be useful in treating patients admitted to the intensive care unit (ICU). Electrical impedance tomography (EIT) has been used as a relatively new imaging technique for this purpose. We presented a patient with pneumonia who was admitted to the ICU after pulmonary thromboembolism (PTE) required to perform bronchoalveolar lavage (BAL). A drainage procedure and subsequent improvement in pulmonary function were monitored using EIT contributed to the treatment process. The patient has been discharged from the hospital with an improved general condition. PMID- 30278409 TI - Temperament and character profiles for children with ADHD with and without tic disorders. AB - There is no research about whether ADHD with tic disorder that temperamental features that differ from the ADHD. This research aimed to identify temperament and character profiles for children with ADHD according to tic disorder by comparing them with a healthy control group. A discriminant analysis was conducted to identify whether temperament and character profiles can discriminate comorbidity. The sample consisted of three groups (N = 40 per group): ADHD alone, ADHD with tic disorder and age- and sex- matched healthy control. The parents of 120 children (mean age 8.57 +/- 1.71 years) completed the Junior Temperament and Character Inventory (JTCI). The two ADHD groups showed higher novelty seeking and low persistence, self-directedness and cooperativeness than the control group. The ADHD alone group had lower scores for persistence and self-directedness than the other two groups. Temperament and character profiles were useful for discriminating ADHD from the control group. However, their discriminating power was relatively low for all three groups. Results indicated that differences in temperament and character in ADHD children were present according to comorbid tic disorders. JTCI's discriminating power for ADHD alone and ADHD with tic disorder was relatively lower than that of the combined ADHD group and the control group. PMID- 30278408 TI - Adherence, insight and disability in paranoid schizophrenia. AB - Insight has long been linked to both prognosis and functioning in patients with schizophrenia; likewise, it is key to treatment adherence. This study seeks to assess the association between insight, adherence to pharmacological treatment, and disability in schizophrenia, and to study the potential mediating role of adherence between insight and disability. Insight (SUMD), adherence (CRS), and disability (WHO-DAS) were measured in 80 clinically stable patients with DSM-IV TR paranoid schizophrenia. Psychopathology was assessed with the Positive and Negative Syndrome Scale (PANSS). In a first step, predictors of disability were identified using linear regression to identify variables related to disability and further a mediation analysis was carried out. Negative symptoms, insight, and adherence account for 54.2% of the variance in disability. Negative symptoms act directly on disability, while the effect of insight on disability is partially mediated by adherence. Insight is key in disability in schizophrenia and should be leveraged in treatment programs. PMID- 30278407 TI - P(v-a)CO2/C(a-v)O2-directed resuscitation does not improve prognosis compared with SvO2 in severe sepsis and septic shock: A prospective multicenter randomized controlled clinical study. AB - PURPOSES: The present study examined the value of P(v-a)CO2/C(a-v)O2 compared with ScvO2 as a target for clinical resuscitation of severe sepsis/septic shock. MATERIALS AND METHODS: 228 patients were randomly divided into a P(v-a)CO2/C(a v)O2-targeted and a ScvO2-targeted therapy group. The effects on hemodynamics, interventional intensity, and outcome were recorded and analyzed. RESULTS: The mean arterial pressure (MAP) of the P(v-a)CO2/C(a-v)O2-targeted therapy group was significantly higher at 3 h, 12 h, 24 h, and 3 days (P < .05). The P(v-a)CO2/C(a v)O2 of the ScvO2-targeted therapy group was significantly higher at each time point after resuscitation (P < .05). However, the CVP, lactate, urine output, ScvO2, and P(v-a)CO2 were not significantly improved. The P(v-a)CO2/C(a-v)O2 targeted therapy group used a smaller fluid volume and required fewer red blood cell transfusions and vasoactive drugs, but these results were also not significant. There were no differences between 28-day and 60-day mortality, APACHEII and SOFA scores, ICU length of stay, residence length of stay, number of days free of vasoactive drugs, or number of ventilator-free days. Post hoc tests revealed no significant differences between these two groups in 28-day survival. CONCLUSION: P(v-a)CO2/C(a-v)O2-directed resuscitation did not improve prognosis compared with ScvO2 in severe sepsis and septic shock. ClinicalTrials.gov Identifier NCT01877798.

These notions are close to those constituting attachment representations. Hoarding is also linked to seeking support from objects. Studies concerning attachment and hoarding suggest that attachment representations may impact seeking or possessing objects. Acquiring objects may give people momentary support, normally provided by the attachment figure in cases of stress. This study aims to better understand the links between attachment and hoarding. One hundred and ninety-seven non-clinical women (M = 30.58) completed two self-report questionnaires on attachment and hoarding behaviors. The results show a link between insecure attachment (preoccupied and fearful) and hoarding. Preoccupied and fearful attachments are characterized by a fear of loss and abandonment. Possession and accumulation of objects in hoarding could help insecure people to deal with these fears. Therefore, insecure attachment appears to be a vulnerability factor in the development of hoarding behaviors. PMID- 30278411 TI - An in-situ gamma-ray spectrometer for the deep ocean. AB - A low resolution subsea gamma-ray spectrometer is developed for monitoring radioactivity in the deep ocean. The detection system provides quantitative results combining experimental and simulated data. The system is tested for pressures up to 456 105 Pa and is demonstrated in the deep sea South of Crete (Greece) at a depth of 2700 m. The minimum detectable activity for 214Bi considering a 7200 s measurement, was found 0.3 Bq/L due to the extremely low background contribution at high energies.

AB - Recent studies have explored how professionals draw boundaries to reach workable solutions in conflictual and contested areas. Yet they neglected to explore the relationships and dynamics between how boundaries are demarcated in rhetoric and in policy. This article examines these relationships empirically through the case of medical cannabis (MC) policy-making in Israel. Drawing on interviews with key stakeholders in the MC policy field, formal policy documents, and observations of MC conferences, this article sheds light on the dynamics between rhetorical boundary-work and what we term regulatory boundary-work, namely setting rules and regulations to demarcate boundaries in actual practice. Results show how certain definitions of and rationales for a discursive separation between "medical" and "recreational" cannabis and between cannabis "medicalization" and "legalization" prevailed and were translated into formal policy, as well as how stakeholders' reactions to this boundary-work produced policy changes and the shifting of boundaries. Both rhetorical and regulatory boundary-works emerge as ongoing contested processes of negotiation, which are linked in a pattern of reciprocal influence. These processes are dominated by certain actors who have greater power to determine how and why specific boundaries should be drawn instead of others.

AB - RATIONALE: Despite a recognised need for mental health and life skills promotion for young people in low- and middle-income countries (LMICs), the evidence base for accessible and effective interventions is limited. OBJECTIVES: The objectives of this study were to determine if a school-based, teacher-led, life skills focused, and manualised intervention was effective in increasing self-efficacy, reducing internalising problems, promoting prosocial behaviour, and developing a sense of connectedness among secondary school students in Uganda. METHOD: A cluster controlled, before-and-after study was employed in four schools, with one school acting as a wait-list control. In total, 620 students aged 13-18 completed baseline questionnaires, with 170 of those completing the same measures post intervention. Interviews were also completed with four teachers and four students who had finished the intervention. Teachers from the intervention schools completed three days of training on the life skills manual and subsequently delivered the programme over a school year. The manual, written by the lead researcher with support from local facilitators, incorporated 24 lessons plans designed to promote mental health and resilience, develop communication skills, and teach life skills for the present and future. Training sessions also provided guidance on pedagogical approaches required to deliver this type of content effectively. RESULTS: Analysis of Covariance (ANCOVA) demonstrated that the intervention group had a significant increase in general self-efficacy, F(1,167) = 20.10, p < .001, eta2 = 0.107, significant reductions in internalising problems (depression/anxiety-like symptoms), F(1,167) = 11.14, p = .001, eta2 = 0.063, and an increase in overall 'Connectedness' F(1,167) = 15.00, p < .001, eta2 = 0.082, when compared to the control group. Effect sizes for these variables were medium. There was an increase in prosocial attitudes/behaviour that did not reach significance after Bonferroni correction. CONCLUSIONS: Despite limitations, including sample size at post-intervention and lack of randomisation, the study demonstrated that it is possible to deliver an effective, school-based, culturally-appropriate life skills intervention, involving local facilitators in design, delivery, and evaluation. PMID- 30278414 TI - Factors influencing the fate of antibiotic resistance genes during thermochemical pretreatment and anaerobic digestion of pharmaceutical waste sludge. AB - The prevalence of antibiotic resistance genes (ARGs) in waste sludge, especially for the pharmaceutical waste sludge, presents great potential risks to human health. Although ARGs and factors affecting their spreading are of major importance for human health, the factors influencing the fate of ARGs during sludge treatment, especially for pharmaceutical sludge treatment are not yet well understood. In order to be able to minimize ARGs spreading, it is important to find what is influencing their spreading. Therefore, certain factors, such as the sludge characteristics, bacterial diversity and community composition, and mobile genetic elements (MGEs) during the advanced AD of pharmaceutical sludge with different pretreatments were studied, and their affinity with ARGs was elucidated by Spearman correlation analysis. Furthermore, multiple linear regression was introduced to evaluate the importance of the various factors. Results showed that 59.7%-88.3% of the variations in individual ARGs and total ARGs can be explained by the corresponding factors. Bacterial diversity rather than specific bacterial community composition affected the fate of ARGs, whereas alkalinity was the most important factor on ARGs among all sludge characteristics investigated in this study. Besides, 66.4% of variation of total ARGs was driven by the changes of MGEs. Multiple linear regression models also reveal the collective effect of these factors on ARGs, and the contributions of each factor impact on ARGs. This study provides more comprehension about the factors impact on the fate of ARGs during pharmaceutical sludge treatment, and offers an approach to evaluate the importance of each factor, which method could be introduced for evaluation of factors influencing ARGs during other types of sludge or wastewater treatment. PMID- 30278415 TI - Impact of prenatal heavy metal exposure on newborn leucocyte telomere length: A birth-cohort study. AB - Arsenic, cadmium and lead are toxic environmental contaminants. They were shown to be associated with telomere length (TL) in adults. Although they can cross the placental barrier, the effect of prenatal exposure of these metals on newborn TL is unknown. The aim of this study was to examine whether prenatal exposure to heavy metals has an impact on newborn leucocyte TL. A birth-cohort study was conducted with 409 pregnant women and their newborns in Myanmar. During the first visit, face-to-face interviews were conducted, and maternal spot urine sampling was performed. Cord blood samples were collected during follow-up. Urinary heavy metal concentration was measured by ICP-MS and adjusted for creatinine. Relative TL was measured by quantitative real-time polymerase chain reaction. The extent of prenatal arsenic, cadmium and lead exposure and their associations with newborn leucocyte TL were assessed using multivariate linear regression. The median values of maternal urinary arsenic, cadmium, and lead concentrations were 73.9, 0.9, and 1.8 MUg/g creatinine, respectively. Prenatal arsenic and cadmium exposure was significantly associated with newborn TL shortening (lowest vs highest quartile, coefficient = - 0.13, 95% CI: - 0.22, - 0.03, p = 0.002, and coefficient = - 0.17, 95% CI: - 0.27, - 0.07, p = 0.001, respectively), and the associations remained robust after adjusting for confounders. There was no significant association between prenatal lead exposure and newborn TL. The present study identified the effect of arsenic and cadmium exposure on TL shortening, even in utero exposure at a lower concentration. PMID- 30278416 TI - A process-based model for pentachlorophenol dissipation in a flooded paddy soil. AB - Process-based models have been widely used for predicting environmental fate of contaminants. Nevertheless, accurate modeling of pentachlorophenol (PCP) dissipation in soils at the millimeter-scale remains a challenge due to the scarcity of observation data and uncertainty associated with model assumptions and estimation of the model parameters. To provide quantitative analysis of PCP dissipation at the anaerobic/aerobic interface of a rhizobox experiment, this study implemented Bayesian parameter estimation for a process-based reactive chemical transport model. The model considered the main transport and transformation processes of chemicals including diffusion, sorption and degradation. The contributions of the processes to PCP dissipation were apportioned both in space and time. Using the maximum-a-posteriori (MAP) estimation of parameters, our model fitted the experimental data better compared with the previous work. Our results indicated that the most reactive zone for PCP dissipation occurred in the layer of 0-2.4 mm where degradation in solid phase dominated the PCP dissipation, while upward diffusion was the main mechanism for the reduction of PCP concentration in deeper layer (2.4-4.8 mm). By considering the coupled reactive transport of PCP and Cl-, the average degrees of PCP dechlorination in each layer were estimated from corresponding total concentrations of PCP and Cl-. The degrees of PCP dechlorination in the ponding water and the top layer of soil profile were highest, while 2,3,4,5- TeCP and 3,4,5- TCP were identified as the main dechlorination products in the soil. This study demonstrated that combining Bayesian estimation with process-based reactive chemical transport model can provide more insights of PCP dissipation at the millimeter-scale. This approach can help to understand complex dissipation mechanisms for other contaminants. PMID- 30278417 TI - Air pollution-derived PM2.5 impairs mitochondrial function in healthy and chronic obstructive pulmonary diseased human bronchial epithelial cells. AB - In order to clarify whether the mitochondrial dysfunction is closely related to the cell homeostasis maintenance after particulate matter (PM2.5) exposure, oxidative, inflammatory, apoptotic and mitochondrial endpoints were carefully studied in human bronchial epithelial BEAS-2B, normal human bronchial epithelial (NHBE) and chronic obstructive pulmonary disease (COPD)-diseased human bronchial epithelial (DHBE) cells acutely or repeatedly exposed to air pollution-derived PM2.5. Some modifications of the mitochondrial morphology were observed within all these cell models repeatedly exposed to the highest dose of PM2.5. Dose- and exposure-dependent oxidative damages were reported in BEAS-2B, NHBE and particularly COPD-DHBE cells acutely or repeatedly exposed to PM2.5. Nuclear factor erythroid 2-p45 related factor 2 (NRF2) gene expression and binding activity, together with the mRNA levels of some NRF2 target genes, were directly related to the number of exposures for the lowest PM2.5 dose (i.e., 2 MUg/cm2), but, surprisingly, inversely related to the number of exposures for the highest dose (i.e., 10 MUg/cm2). There were dose- and exposure-dependent increases of both nuclear factor kappa-B (NF-kappaB) binding activity and NF-kappaB target cytokine secretion in BEAS-2B, NHBE and particularly COPD-DHBE cells exposed to PM2.5. Mitochondrial ROS production, membrane potential depolarization, oxidative phosphorylation, and ATP production were significantly altered in all the cell models repeatedly exposed to the highest dose of PM2.5. Collectively, our results indicate a cytosolic ROS overproduction, inducing oxidative damage and activating oxygen sensitive NRF2 and NF-kB signaling pathways for all the cell models acutely or repeatedly exposed to PM2.5. However, one of the important highlight of our findings is that the prolonged and repeated exposure in BEAS-2B, NHBE and in particular sensible COPD-DHBE cells further caused an oxidative boost able to partially inactivate the NRF2 signaling pathway and to critically impair mitochondrial redox homeostasis, thereby producing a persistent mitochondrial dysfunction and a lowering cell energy supply.

PMID- 30278419 TI - Impairments in reversal learning following short access to cocaine self administration. AB - BACKGROUND: Cocaine use disorder is characterized by compulsive drug-seeking that persists long into abstinence. Work using rodent models of cocaine addiction has found evidence for reversal learning deficits 21 days after non-contingent cocaine administration and 60 days after self-administration. Here we sought to determine if a deficit in reversal learning is present 3-4 weeks after cessation of cocaine self-administration, when relapse to cocaine-seeking is robust. Conversely, we hypothesized that reversal learning training would protect against relapse, similar to other forms of environmental enrichment. METHODS: Male rats underwent short access (ShA, 2 h/10d) or long access (LgA, 1 h/7d then 6 h/10d) cocaine self-administration, followed by 21-29 days of abstinence. During abstinence, a subset of rats underwent training in a plus-maze that required an egocentric strategy to earn a sucrose reward. Following response acquisition and retention, the ability to reverse the spatial navigation strategy was tested. RESULTS: Total trials to criteria and total errors made did not differ between the groups during response acquisition, retention, or reversal. On the first reversal test, ShA rats performed better than LgA and control rats. ShA rats' performance worsened over time. There were no effects of cognitive training or length of cocaine access on context-primed relapse of cocaine-seeking. CONCLUSIONS: The present data indicate that perhaps LgA cocaine self administration does not produce adaptations to regions mediating context-primed relapse as it does for cocaine and cocaine-associated cue-induced reinstatement of drug-seeking. A time-dependent deficit in reversal learning was found only in ShA rats. Reversal learning training did not protect against cocaine relapse. PMID- 30278420 TI - Reuse of materials from a Sustainable Drainage System device: Health, Safety and Environment assessment for an end-of-life Pervious Pavement Structure. AB - Pervious pavement systems can have a life span of about 20years but, at end-of life, it becomes necessary to evaluate the state of the infrastructure to determine whether they pose a health and safety risk to workers during dismantling, and also determine potential reuse of the waste material generated. In this paper, we report of an investigation conducted to evaluate whether Pervious pavement systems are hazardous to human health at end-of-life and also to assess the mobility of the stormwater pollutants trapped in the system as a measure of their potential release to receiving systems such as water-bodies and groundwater systems. After decommissioning, the pervious pavement structure was sampled for analysis including Gas Chromatography, inductively coupled plasma spectroscopy and, leachate analysis. Results show that carcinogenic risks were significantly below the regulatory limit of 1*10-6 while, the hazard quotients and cumulative hazard indices were also below regulatory value of 1, based on United States Environmental Protection Agency standards. Furthermore, mean concentrations of benzene, toluene, ethylbenzene and xylene were significantly less than the UK soil guideline values. The results of the leachate analysis show that the metals of concern, Pb, Zn, Cr, Ni, Cd and Cu were all below the threshold for reuse applications such as irrigation purposes as they were all below the regulatory limits such as Food and Agriculture Organization and, United States Environmental Protection Agency standards. Finally, the evaluation of potential reuse and recycling purposes indicate that wastes generated from the dismantling of the PPS are within limits for recycling as aggregates for other civil engineering projects as per European Union standards. This has potential to enhance UK's drive to achieve the target of 70% level of construction & demolition waste recovery for reuse and recycling by the year 2020 as per European Union Water Framework Directive. PMID- 30278421 TI - Impact of the widespread pharmaceutical pollutant fluoxetine on behaviour and sperm traits in a freshwater fish. AB - Pharmaceutical pollutants are detected in aquatic habitats and wildlife tissues globally. One widespread contaminant of major concern is the antidepressant fluoxetine, which can affect behavioural and physiological processes in non target species. Despite this, effects of fluoxetine on wildlife behaviour have seldom been investigated across multiple fitness-related contexts, especially at environmentally realistic concentrations. Accordingly, we examined impacts of 35 day fluoxetine exposure at two environmentally relevant concentrations (31 and 374 ng/L) across a suite of fitness-related contexts in wild-caught male mosquitofish (Gambusia holbrooki). First, we investigated anxiety-related behaviours (boldness, exploration and activity) in a novel environment (maze arena) and found no significant impacts of exposure. Second, we tested effects of fluoxetine in a reproductive context, including mating behaviour and sperm quality. We found that, relative to controls, fluoxetine exposure resulted in males spending a greater amount of time pursuing females. Further, low-exposed males were more likely to attempt copulation than unexposed males. Lastly, we investigated across-context behavioural correlations, and how fluoxetine exposure might affect such relationships. A significant positive correlation was detected in control fish between activity levels in the maze and time spent pursuing females in the reproductive assay. This relationship was disrupted by fluoxetine at both exposure levels. This is the first evidence that field-detected concentrations of a pharmaceutical pollutant can disturb across-context behavioural correlations in wildlife. Our findings provide clear evidence that fluoxetine can produce context-specific behavioural effects in fish and underscore how pharmaceutical exposure at field-detected concentrations can induce important shifts in wildlife behaviour. PMID- 30278422 TI - Use of integrated biomarker indexes for assessing the impact of receiving waters on a native neotropical teleost fish. AB - In the field of aquatic ecotoxicology, indexes obtained from a battery of biomarkers have proved to be a useful tool for assessing quantifiable and integrated health responses of organisms exposed to pollutants. The objective of this work was to evaluate the effects of exposure to the Reconquista River water (RR) on adults of Cnesterodon decemmaculatus using different integrated indexes. We conducted a 12-d laboratory assay involving the exposure of fish to RR, a negative control (moderately hard water - MHW medium), and a positive control (for genotoxicity with MHW + Cyclophosphamide, CP). There were measured metabolic (food intake and specific assimilation, specific metabolic rate, oxygen extraction efficiency, ammonia excretion, and ammonia quotient), genotoxic (comet assay, micronucleus test, and nuclear abnormalities), morphological variables (total length, body and liver weight) and biochemical variables (Electron Transport System - ETS, Acetylcholinesterase activity - AChE, Catalase - CAT, Glutathione-S-transferase - GST, Glutathione content - GSH and tissue proteins). These variables were grouped into different indexes: morphological (Condition Factor - K and Liver Somatic Index-LSI), metabolic (Scope for Growth-SFG), genetic damage (GDI) and integrated biomarker response - IBR (AChE brain, CAT, GST and GSH liver, GSH gills, ETS muscle) indexes. Results indicated that RR water induced metabolic, biochemical and genetic damages. The SFG, GDI and IBR were suitable to assess the effects of exposure to an environmental sample in an integrated approach, reducing uncertainty due to inherent biomarker variability. These indexes have emerged as promising tools for environmental monitoring studies. PMID- 30278423 TI - Overdose fertilization induced ammonia-oxidizing archaea producing nitrous oxide in intensive vegetable fields. AB - Little is known about the effects of nitrogen (N) fertilization rates on ammonia oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) and their differential contribution to nitrous oxide (N2O) production, particularly in greenhouse based high N input vegetable soils. Six N treatments (N1, N2, N3, N4, N5 and N6 representing 0, 293, 587, 880, 1173 and 1760 kg N ha-1 yr-1, respectively) were continuously managed for three years in a typically intensified vegetable field in China. The aerobic incubation experiment involving these field-treated soils was designed to evaluate the relative contributions of AOA and AOB to N2O production by using acetylene or 1-octyne as inhibitors. The results showed that the soil pH and net nitrification rate gradually declined with increasing the fertilizer N application rates. The AOA were responsible for 44-71% of the N2O production with negligible N2O from AOB in urea unamended control soils. With urea amendment, the AOA were responsible for 48-53% of the N2O production in the excessively fertilized soils, namely the N5-N6 soils, while the AOB were responsible for 42-55% in the conventionally fertilized soils, namely the N1-N4 soils. Results indicated that overdose fertilization induced higher AOA-dependent N2O production than AOB, whereas urea supply led to higher AOB-dependent N2O production than AOA in conventionally fertilized soils. Additionally, a positive relationship existed between N2O production and NO2- accumulation during the incubation. Further mechanisms for NO2--dependent N2O production in intensive vegetable soils therefore deserve urgent attention. PMID- 30278424 TI - Spatially-explicit estimate of soil nitrogen stock and its implication for land model across Tibetan alpine permafrost region. AB - Permafrost soils store a large amount of nitrogen (N) which could be activated under the continuous climate warming. However, compared with carbon (C) stock, little is known about the size and spatial distribution of permafrost N stock. By combining measurements from 519 pedons with two machine learning models (supporting vector machine (SVM) and random forest (RF)), we estimated the size and spatial distribution of N stock across the Tibetan alpine permafrost region. We then compared these spatially-explicit N estimates with simulated N stocks from the Community Land Model (CLM). We found that N density (N amount per area) in the top three meters was 1.58 kg N m-2 (interquartile range: 1.40-1.76) across the study area, constituting a total of 1802 Tg N (interquartile range: 1605 2008), decreasing from the southeast to the northwest of the plateau. N stored below 1 m accounted for 48% of the total N stock in the top three meters. CLM4.5 significantly underestimated the N stock on the Tibetan Plateau, primarily in areas with arid/semi-arid climate. The process of biological N fixation played a key role in the underestimation of N stock prediction. Overall, our study highlights that it is imperative to improve the simulation of N processes and permafrost N stocks in land models to better predict ecological consequences induced by rapid and widespread permafrost degradation. PMID- 30278425 TI - The exposure of slums to high temperature: Morphology-based local scale thermal patterns. AB - Heat exposure has become a global threat to human health and life with increasing temperatures and frequency of extreme heat events. Considering risk as a function of both heat vulnerability and hazard intensity, this study examines whether poor urban dwellers residing in slums are exposed to higher temperature, adding to their vulnerable demographic and health conditions. Instead of being restricted by sampling size of pixels or other land surface zones, this study follows the intrinsic latent patterns of the heat phenomenon to examine the association between small clusters of slums and heat patterns. Remotely sensed land surface temperature (LST) datasets of moderate resolution are employed to derive the morphological features of the temperature patterns in the city of Ahmedabad, India at the local scale. The optimal representations of temperature pattern morphology are learnt automatically from temporally adjacent images without manually choosing model hyper-parameters. The morphological features are then evaluated to identify the local scale temperature pattern at slum locations. Results show that in particular locations with slums are exposed to a locally high temperature. More specifically, larger slums tend to be exposed to a more intense locally high temperature compared to smaller slums. Due to the small size of slums in Ahmedabad, it is hard to conclude whether slums are impacting the locally high temperature, or slums are more likely to be located in poorly built places already with a locally high temperature. This study complements the missing dimension of hazard investigation to heat-related risk analysis of slums. The study developed a workflow of exploring the temperature patterns at the local scale and examination of heat exposure of slums. It extends the conventional city scale urban temperature analysis into local scales and introduces morphological measurements as new parameters to quantify temperature patterns at a more detailed level. PMID- 30278426 TI - SCJ osteoarthritis: The significance of joint surface location for diagnosis. AB - An evaluation of the method used to diagnose sternoclavicular joint (SCJ) osteoarthritis (OA) in skeletal remains is presented, with particular attention given to the anatomy of the joint. The current palaeopathological diagnostic criteria used to identify SCJ OA were found to be appropriate for both the sternal and clavicular surfaces of the SCJ, with eburnation indicating perforation of the intra-articular disc and advanced disease. Eburnation was found to occur rarely in the SCJ, and if used as the sole diagnostic criterion would result in an underestimation of SCJ OA prevalence in archaeological assemblages. A key finding was the identification of changes characteristic of OA but confined to the attachment zone of the intra-articular disc on the clavicular surface of the SCJ. As this area of the joint is non-articular, and not normally covered with articular cartilage, a diagnosis of OA would be inaccurate and instead it should be considered as an enthesopathy. It is likely that SCJ OA has been incorrectly identified and over-diagnosed in the archaeological record in the past. More histological research into the disc attachment and its degeneration is required before this can be confirmed. PMID- 30278427 TI - Influence of polyphenolic content on the in vitro allergenicity of old and new apple cultivars: A pilot study. AB - OBJECTIVES: More than 70% of birch pollen-allergic individuals are affected by a cross-allergy from apples. The aim of this study was to determine if an increased polyphenolic content of apples is inversely related to clinical allergic reactions in sufferers. METHODS: The polyphenolic content of two old and two new apple cultivars was analyzed using high performance liquid chromatography. The in vitro concentration of sulfidoleukotrienes and the CD63 basophil activation of 27 birch pollen sufferers with cross-reactivity to apples were determined with cellular antigen stimulation and basophil activation tests after incubation with different apple cultivars. RESULTS: The flesh of old cultivars was characterized by significantly higher total polyphenolic content (86.1 +/- 5.5 ug/g) than that of new cultivars (24.7 +/- 7.2 ug/g). The concentration of sulfidoleukotrienes and the CD63 basophil activation of old apple cultivars was up to 62% lower than new ones and decreased as the degree of enzymatic browning increased. CONCLUSION: Old apples cultivars are better tolerated than new ones by birch pollen-allergic individuals. The in vitro allergenicity (activation of effector cells) of apples depends on the total polyphenolic content and the degree of enzymatic browning. PMID- 30278428 TI - Impact of the preoperative use of synbiotics in colorectal cancer patients: A prospective, randomized, double-blind, placebo-controlled study. AB - OBJECTIVES: Gastrointestinal microflora is involved in the development and regulation of the immune response. Non-pathogenic bacteria are important to prevent the development and subsequent invasion of enteropathogenic bacteria. Surgical trauma and intestinal preparation can disrupt the intestinal microbiota balance. Modulating the microbiota in the preoperative period in patients with colorectal cancer may have an effect on the occurrence of postoperative complications. The aim of this study was to assess the effect of preoperative synbiotic administration in patients with colorectal cancer subjected to colorectal resection. METHODS: This was a prospective, randomized, double-blind, placebo-controlled study of 73 patients with colorectal cancer. Eight days before surgery, patients were randomized to receive either synbiotics (Simbioflora, Farmoquimica, Sao Paulo, Brazi) or placebo (maltodextrin). The envelopes were identical and labeled A or B. All patients underwent nutritional assessment and measurements of C-reactive protein (CRP), interleukin (IL)-6, serum albumin, and transferrin. Patients were given a diluted envelope in 100mL of water twice daily for 7 d. The occurrence of infectious or non-infectious complications, time of antibiotic use, duration of hospitalization, and occurrence of deaths were recorded for 30 d postoperatively. RESULTS: Mean age, demographic data, and tumor staging were similar between the groups at baseline. After 7 d of synbiotic intake, there were significant reductions in IL-6 levels (163.2 +/- 19.5 versus 138.8 +/- 12.5, P < 0.001) and CRP (10 +/- 5.2 versus 7.17 +/- 3.2, P < 0.001), whereas the control group did not present significant changes I IL-6 levels (154.2 +/- 18.3 versus 160.9 +/- 18.6, NS) or CRP (10.6 +/- 6.18 versus 10.4 +/- 6.1, NS). Serum albumin and transferrin did not show significant changes. Postoperative infectious complications occurred in 2.8% of patients in the synbiotic group and in 18.9% of the control group (P = 0.02). The mean antibiotic usage time was 1.42 +/- 0.5 d in the synbiotic group and 3.74 +/- 4.3 d in the control group (P < 0.001). The mean hospital length of stay was 3 +/- 1 d in the synbiotic group and 4 +/- 18 in the control group (P < 0.001). Three deaths were reported in the control group and none in the synbiotic group (P = 0.115). CONCLUSIONS: The use of synbiotics for 7 d preoperatively in patients with colorectal cancer attenuates the inflammatory state and is associated with reductions in morbidity, hospital length of stay, and use of antibiotics. PMID- 30278429 TI - Effect of alpha-linolenic acid in combination with the flavonol quercetin on markers of cardiovascular disease risk in healthy, non-obese adults: A randomized, double-blinded placebo-controlled crossover trial. AB - OBJECTIVES: Alpha-linolenic acid (ALA) and quercetin are characteristic compounds in plant-based diets. Cardioprotective effects have been described for both substances, although a possible benefit of combining ALA and quercetin has not, to our knowledge, been evaluated yet. The aim of this study was to investigate the potential independent and additive effects of ALA and quercetin on blood pressure (BP) and lipid and glucose metabolism, as well as on biomarkers of inflammation, oxidative stress, and antioxidant status in healthy, non-obese men and women. Another aim was to examine whether chronic supplementation of supranutritional doses of quercetin would result in an accumulation of plasma quercetin concentration over time. METHODS: In a double-blinded, placebo controlled crossover trial, healthy volunteers were randomized to receive 3.6g/d ALA plus 190mg/d quercetin or placebo for 8 wk. Data from 67 individuals (34 men, 33 women, mean age: 24.6 y) were assessed. RESULTS: Plasma quercetin, tamarixetin, isorhamnetin, and kaempferol increased significantly from baseline to study end with ALA + quercetin but not with ALA + placebo. No significant effect on office systolic BP, mean 24 h ambulatory BP (ABP), or mean daytime ABP was seen in either study group. Both interventions significantly decreased total cholesterol, low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol, and apolipoprotein B to a similar extent. No effect on high-density lipoprotein cholesterol, apolipoprotein A1, glucose, uric acid, oxidized low density lipoprotein, C-reactive protein, or lipid-adjusted retinol, alpha tocopherol, or beta-carotene was seen in either group. CONCLUSION: Although dietary supplements of 3.6g/d ALA over an 8-wk period improved lipid profiles in healthy adults, antioxidative and oxidative status, inflammation, and BP remained unchanged. No evidence was seen for an additive or synergistic effect of ALA plus quercetin on markers of cardiovascular disease risk. PMID- 30278430 TI - Effect of resveratrol supplementation on lipid profile in subjects with dyslipidemia: A randomized double-blind, placebo-controlled trial. AB - OBJECTIVES: The aim of this study was to explore the effect of resveratrol supplementation on lipid profile in individuals with dyslipidemia. METHODS: Apparently healthy men and non-pregnant women 20 to 65 y of age with new diagnosis of dyslipidemia were enrolled in a randomized double-blind, placebo controlled trial and randomly allocated to receive either resveratrol 100mg/d or placebo (sucrose 0.5 g/d) for 2 mo. Smoking, alcohol intake, diabetes, acute or chronic renal or hepatic diseases, malignancy, cardiovascular disease, serum triacylglycerol levels >=400mg/dL, low-density lipoprotein cholesterol levels >=190mg/dL, and consumption of lipid-lowering drugs or supplements containing resveratrol were exclusion criteria. RESULTS: Seventy-one individuals with new diagnosis of dyslipidemia were enrolled and randomly allocated to the resveratrol (n = 35) or placebo groups (n = 36). At baseline, there were no significant differences between the study groups. After intervention period, individuals in the resveratrol group showed a significant decrease in total cholesterol (201.4 +/- 34.4 versus 220.6 +/- 37.4, P = 0.04) and triacylglycerol (133.4 +/- 55.3 versus 166.7 +/- 68.5, P = 0.04) concentrations compared with the placebo group, without significant statistical differences for high-density lipoprotein cholesterol and low-density lipoprotein cholesterol levels. CONCLUSION: The results suggest that resveratrol supplementation significantly reduces total cholesterol and triacylglycerol concentrations in individuals with dyslipidemia. PMID- 30278431 TI - Faculty perspectives on the use of standardized versus non-standardized oral examinations to assess medical students. AB - Objectives: To determine if faculty perceive standardized oral examinations to be more objective and useful than the non-standardized format in assessing third year medical students' learning on the obstetrics and gynecology rotation. Methods: Obstetrics and gynecology faculty at three teaching hospitals were sampled to complete a survey retrospectively comparing the standardized oral examination (SOE) and non-standardized or traditional oral examinations (TOE). A Likert scale (0-5) was used to assess satisfaction, objectivity, and usefulness of SOE and TOE. Wilcoxon signed rank test was performed to compare median Likert scale scores for each survey item. A Spearman's correlation coefficient was used to investigate the relationship between the perceived level of objectivity and SOE characteristics. For qualitative measures, content analysis was applied. Results: Sixty-six percent (n=25) of eligible faculty completed the survey. Faculty perceived the standardized oral examination as significantly more objective compared with the non-standardized (z=-3.15, p=0.002). Faculty also found SOE to be more useful in assessing overall clerkship performance (z=-2.0, p<0.05). All of the survey participants were willing to administer the standardized examination again. Faculty reported strengths of the SOE to be uniformity, fairness, and ease of use. Major weaknesses reported included inflexibility and decreased ability to assess students' higher order reasoning skills. Conclusions: Faculty found standardized oral examinations to be more objective in assessing third-year medical students' clinical competency when compared with a non-standardized approach. This finding can be meaningfully applied to medical education programs internationally. PMID- 30278432 TI - Overcoming Drug Resistance in Colon Cancer by Aptamer-Mediated Targeted Co Delivery of Drug and siRNA Using Grapefruit-Derived Nanovectors. AB - BACKGROUND/AIMS: Multidrug resistance (MDR) is the most common cause of chemotherapy failure. Upregulation of P-glycoprotein (P-gp) is one of the main mechanisms underlying MDR. METHODS: In this study, we developed a targeted drug and small interfering (si)RNA co-delivery system based on specific aptamer conjugated grapefruit-derived nanovectors (GNVs) that we tested in MDR LoVo colon cancer cells. The internalization of nanovectors in cancer cells was tested by fluorescence microscopy and flow cytometry. The anti-cancer activity in vitro was determined by colony formation and cell apoptosis assays. The biodistribution of nanovectors was analyzed by live imaging and the anti-cancer activity in vivo was observed. RESULTS: GNVs loaded with aptamer increased doxorubicin (Dox) accumulation in MDR LoVo cells, an effect that was abolished by pretreatment with DNase. The LA1 aptamer effectively promoted nanovector internalization into cells at 4 degrees C and increased the targeted delivery of Dox to tumors. Constructs harboring Dox, LA1, and P-gp siRNA more effectively inhibited proliferation and enhanced apoptosis in cultured MDR LoVo cells while exhibiting more potent anti tumor activity in vivo than free Dox or GNVs loaded with Dox alone or in conjunction with LA1, an effect that was associated with downregulation of P-gp expression. CONCLUSION: This GNV-based system may be an effective strategy for overcoming MDR in clinical settings. PMID- 30278433 TI - Circular RNA Expression Profile and Analysis of Their Potential Function in Psoriasis. AB - BACKGROUND/AIMS: Circular RNAs (circRNAs) are evolutionary conserved circular non coding RNAs that play a role in several diseases by sequestering (sponging) microRNAs (miRNAs). However, their role in psoriasis remains unclear. In the present study, we investigated the expression of circRNAs and analyzed their potential functions in psoriasis. METHODS: The SBC human ceRNA array V1.0 was used to analyze circRNA expression in psoriatic lesions and normal healthy skin tissues. Functional analyses were performed using Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis. Putative miRNA response elements (MREs) were identified using miRNA target prediction software. Six upregulated circRNAs were verified by quantitative real-time reverse transcription polymerase chain reaction in psoriatic lesions and healthy skin tissues. RESULTS: A total of 4956 circRNAs (3016 upregulated and 1940 downregulated; fold change >=2 and p< 0.05) were identified as differentially expressed in psoriasis. Furthermore, 4405 MREs were identified among the differentially expressed circRNAs. hsa_circ_0061012 was upregulated in psoriatic lesions compared with normal healthy skin tissues. The top five MREs of hsa_circ_0061012 were hsa-miR-7157-5p, hsa-miR-4769-3p, hsa-miR-6817-5p, hsa-miR 4310, and hsa-miR-6882-3p. GO analysis was carried out to investigate the biological functions enriched among the upregulated targets of five miRNAs in psoriasis. The GO analysis identified that most of top 30 of GO enrichment are related to psoriasis. CONCLUSION: hsa_circ_0061012 might be a candidate biomarker for psoriasis. The results provide a new perspective for a better understanding of ceRNA-mediated gene regulation in psoriasis, and provide a novel theoretical basis for further studies on the function of circRNA in psoriasis. PMID- 30278434 TI - Micropapular Cutaneous Sarcoidosis Reviewed. AB - BACKGROUND: Micropapular cutaneous sarcoidosis (MPCS) is a rare variant of sarcoidosis. Herein we review the literature and include a recent case of MPCS discussing pathogenesis, diagnosis, treatment, and prognosis. METHOD: A review was conducted using the terms "micropapular sarcoidosis" and "micropapular sarcoid." A recent case of a 50-year-old male patient with biopsy-identified MPCS was also included in the review. RESULTS: In total, 12 cases with an aggregate of 18 patients were included in the review. Presentation among all patients was consistent, with scattered, occasionally pruritic, faintly erythematous shiny white papules. Skin biopsy demonstrated noncaseating granulomas. Systemic prednisone, oxytetracycline, and hydroxychloroquine, as well as topical betamethasone, were used for therapy. CONCLUSION: In our review there does not seem to be a clear link as to the definite cause of the MPCS. While the relationships to tuberculosis and autoimmunity seem to be often emphasized, there was no clear association with either etiology. PMID- 30278435 TI - Liver Maximum Capacity: A Novel Test to Accurately Diagnose Different Stages of Liver Fibrosis. AB - AIM: To assess the diagnostic accuracy of liver maximum capacity (LiMAx(r)) test compared to transient elastography (TE) and serum biomarkers for the noninvasive detection of different stages of liver fibrosis and cirrhosis. PATIENTS AND METHODS: We retrospectively correlated LiMAx(r), TE, aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (AAR), AST-to-platelet ratio index (APRI), and fibrosis-4 (FIB-4) score with histological specimens in 102 patients with chronic liver disease (CLD) who underwent liver biopsy (either percutaneously or via mini-laparoscopy) at the University Clinic of Essen between 10/2016 and 12/2017. RESULTS: Median LiMAx(r) values showed a tendency to decrease in accordance with increasing histological degree of fibrosis based on the Desmet scoring system (F0: 446.5 [381.0-592.5] ug/h/kg, F1: 405.0 [343.0 547.0] ug/h/kg, F2: 337.0 [250.0-394.0] ug/h/kg, F3: 281.0 [262.0-364.0] ug/h/kg, and F4: 181.5 [130.0-256.5] ug/h/kg. Furthermore, -LiMAx(r) was superior to TE, FIB-4, AAR, and APRI in detecting different stages of fibrosis, while Spearman's rank correlation test showed a statistically significant association of -0.68, 0.62, 0.61, 0.46, and 0.42, respectively. However, the combination of TE and LiMAx(r) had the highest diagnostic accuracy in detecting liver cirrhosis (sensitivity 88.9%, specificity 84.6%, Youden index 0.735). CONCLUSION: Enzymatic liver function measured by LiMAx(r) showed strong correlation with histology in patients with CLD irrespective of its underlying etiology and was superior to TE and serum biomarkers, possibly making it useful as a novel and noninvasive tool for the determination of hepatic disease severity. PMID- 30278436 TI - Laitinen's Subgenual Cingulotomy: Anatomical Location and Case Report. AB - BACKGROUND: The widespread use of deep brain stimulation (DBS) for movement disorders has renewed the interest in DBS for psychiatric disorders. Lauri Laitinen was a pioneer of stereotactic psychosurgery in the 1950s to 1970s, especially by introducing the subgenual cingulotomy. Our aim here was to verify the anatomical target used by Laitinen, to report on a patient who underwent this procedure, and to review the literature. MATERIALS AND METHODS: The records of Helsinki University Hospital were searched for psychosurgical cases performed between 1970 and 1974. Alive consenting patients were interviewed and underwent a brain MRI. RESULTS: We found 1 patient alive who underwent subgenual cingulotomy in 1971 for obsessive thoughts, anxiety, and compulsions, diagnosed at that time as "schizophrenia psychoneurotica." MRI showed bilateral subgenual cingulotomy lesions (254 and 160 mm3, respectively). The coordinates of the center of the lesions in relation to the midcommissural point for the right and left, respectively, were: 7.1 and 7.9 mm lateral; 0.2 mm inferior and 1.4 mm superior, and 33.0 and 33.9 anterior, confirming correct subgenual targeting. The patient reported retrospective satisfactory results. CONCLUSIONS: The lesion in this patient was found to be in the expected location, which gives some verification of the correct placement of Laitinen's subgenus cingulotomy target. PMID- 30278437 TI - Validity of Laparoscopic Gastrectomy in the Elderly. AB - OBJECTIVES: This study aimed to investigate the validity of laparoscopic gastric cancer surgery in elderly patients. METHODS: A total of 202 patients who underwent laparoscopic gastrectomy for gastric cancer between January 2007 and December 2016 were divided into an elderly group (age >=75 years, n = 36) and a control group (age < 75 years, n = 166). The patients' clinicopathological data were reviewed. RESULTS: The overall morbidity rate was relatively higher in the elderly group (16.7 vs. 11.4%, p = 0.389), whereas the incidence of serious complications >=grade III according to the Clavien-Dindo classification did not increase significantly in the elderly group (8.3 vs. 7.8%, p = 0.920). Univariate and multivariate analyses revealed that age >=75 years was not a significant predictive factor of postoperative morbidity (p = 0.568). There was no significant difference in the 5-year overall survival rate of patients with pathological stage I gastric cancer between the groups (97.1 vs. 96.1%, p = 0.704; hazard ratio, 0.669; 95% confidence interval, 0.036-3.692). CONCLUSIONS: Laparoscopic gastrectomy has an acceptable morbidity rate in elderly patients, and the long-term outcome of patients with stage I gastric cancer was similar to that of the control group. PMID- 30278438 TI - Association of Environmental Tobacco Smoke with the Risk of Severe Early Childhood Caries among 3-Year-Old Japanese Children. AB - Severe early childhood caries (S-ECC) has serious consequences for primary dentition, affecting the overall health, well-being, and quality of life of the child. The aim of this study was to investigate the association of risk factors, including environmental tobacco smoke (ETS), with S-ECC in 3-year-old Japanese children by a cross-sectional study. Study subjects were 2,825 children aged 3 years old. Of these individuals, after excluding the study subjects with missing values, a total of 2,277 children were included in the present analysis. The self administered questionnaire included such items as sex, whether a smoker resides in the home, the number of smokers in the home, snack time, drinking or eating sweets after dinner, frequency of parents brushing their child's teeth, the use of fluoride toothpaste, and socioeconomic status. We obtained the number of decayed, missing, or filled teeth per person (dmft) from dental examinations. Logistic regression analysis was performed to estimate the odds ratio for S-ECC. The average number of decayed, missing, and filled teeth (dmft index) was 0.77. The prevalence of dental caries was 20.6%. There was at least 1 smoker in the homes of 1,370 subjects (60.2%). After excluding items of multicollinearity, the results of multivariate analysis were as follows: drinking or eating sweets after dinner, irregular snack times, parents brushing their child's teeth less frequently, existence of smokers in the home, and no residence tax were significantly associated with S-ECC. This study suggests that there is a significant association between ETS from family members and S-ECC. PMID- 30278439 TI - lncRNA AFAP1-AS1 Promotes Migration and Invasion of Non-Small Cell Lung Cancer via Up-Regulating IRF7 and the RIG-I-Like Receptor Signaling Pathway. AB - BACKGROUND/AIMS: Accumulating evidence has highlighted the importance of long non coding RNAs (lncRNAs) as competing endogenous RNAs (ceRNAs) in tumor biology. Among others, actin filament-associated protein 1 antisense RNA 1 (AFAP1-AS1) has been associated with non-small cell lung cancer (NSCLC). However, it remains unclear how AFAP1-AS1 participates in the development and progression of NSCLC. METHODS: The peripheral blood samples were collected from patients with NSCLC. White blood cell subsets were classified and levels of interleukin (IL)-10, IL-12 and IFN-gamma in serum were measured. We then identified its target gene of AFAP1 AS1 via bioinformatics methods. NSCLC cell line with the highest expression of AFAP1-AS1, i.e. H1975 was selected for in vitro experiments. A series of inhibitor, vector and siRNA were employed to validate the regulatory mechanisms of AFAP1-AS1 in the development and progression of NSCLC. Cell proliferation was detected by MTT assay and EdU staining. Cell migration and invasion, and cell cycle and apoptosis were measured by transwell assay and flow cytometry, respectively. RESULTS: A high expression of AFAP1-AS1 was identified in NSCLC, alongside with a reduced level of IL-12 and increased levels of IL-10 and interferon (IFN)-gamma. Aberrant expressions of AFAP1-AS1 were associated with pathological grade, TNM staging and metastatic potential of NSCLC. AFAP1-AS1 could activate interferon regulatory factor (IRF)7, the retinoid-inducible protein (RIG)-I-like receptor signaling pathway and Bcl-2 in vitro. Over expression of AFAP1-AS1 promoted NSCLC cell proliferation, invasion and migration while inhibiting cell apoptosis. CONCLUSION: lncRNA AFAP1-AS1 promotes migration and invasion of non-small cell lung cancer via up-regulating IRF7 and the RIG-I like receptor signaling pathway. PMID- 30278441 TI - Mission Statement. PMID- 30278440 TI - Diet and Lifestyle Role in Homocysteine Metabolism in Turner's Syndrome. AB - OBJECTIVE: Patients with Turner syndrome (TS) have an unfavorable cardiometabolic profile. Hyperhomocysteinemia is a potential cardiovascular risk factor influenced by genetic and environmental factors, therapies, unbalanced diets and other lifestyle factors. We retrospectively studied the relationship between total plasma homocysteine (Hcy), serum vitamin B12 (B12) and folate concentration (s-F) in TS patients, taking into account the genetic profile, diet, smoking habits, hormonal therapies and dietary supplements of the subjects. PATIENTS AND METHODS: We evaluated 50 TS patients (31.5 ? 12.5yrs). Medication, including vitamin supplementation, was obtained. Eating habits, cigarette smoking, alcohol and coffee consumption were investigated using phone interviews. Levels of Hcy metabolism parameters were classified by using the relevant cut-off value for an adult population and compared with a reference sample drawn from the general population. RESULTS: Inadequate Hcy and B12 levels were noted, despite vitamin supplementation. Holotranscobalamin (HoloTC) was above the relevant cut-off in the population and supplemented subjects showed mean levels lower than non supplemented subjects (p = 0.005). Dietary supplementation (p = 0.038), lifestyle (coffee consumption p = 0.01) and hormonal replacement therapy (p = 0.02) are important factors for Hcy metabolism. No genetic influence on Hcy levels was noted. Multivariable regression analysis identified vitamin supplementation (p = 0.045) as the only independent predictor of increased Hcy levels. CONCLUSION: Cardiovascular risk in Turner syndrome can be reduced using educational approaches to a healthy lifestyle with dietary guidelines. Besides this, we also recommend measuring HoloTC for the prompt detection of B12 deficiency and to consider hormone replacement therapy in the biochemical assessment of homocysteine in TS. PMID- 30278443 TI - Evaluation of an Intubation Readiness Score to Assess Neonatal Sedation before Intubation. AB - BACKGROUND: Premedication for neonatal intubation facilitates the procedure and reduces stress and physiological disturbances. However, no validated scoring system to assess the effect of premedication prior to intubation is available. OBJECTIVE: To evaluate the usefulness of an Intubation Readiness Score (IRS) to assess the effect of premedication prior to intubation in newborn infants. METHODS: Two-center prospective study in neonates who needed endotracheal intubation. Intubation was performed using a standardized procedure with propofol 1-2 mg/kg as premedication. The level of sedation was assessed with the IRS by evaluating the motor response to a firm stimulus (1 = spontaneous movement; 2 = movement on slight touch; 3 = movement on firm stimulus; 4 = no movement). Intubation was proceeded if an adequate effect, defined as an IRS of 3 or 4, was reached. IRS was compared to the quality of intubation measured with the Viby Mogensen intubation score. RESULTS: A total of 115 patients, with a median gestational age of 27.7 weeks (interquartile range 5.3) and a median birth weight of 1,005 g (interquartile range 940), were included. An adequate IRS was achieved in 105 patients, 89 (85%) of whom also had a good Viby-Mogensen intubation score and 16 (15%) had an inadequate Viby-Mogensen intubation score. The positive predictive value of the IRS was 85%. CONCLUSIONS: Preintubation sedation assessment using the IRS can adequately predict optimal conditions during intubation in the majority of neonates. We suggest using the IRS in routine clinical care. Further research combining the IRS with other parameters could further improve the predictability of adequate sedation during intubation.

PMID- 30278442 TI - The Profile of Genetic Mutations in Papillary Thyroid Cancer Detected by Whole Exome Sequencing. AB - BACKGROUND/AIMS: The purpose of the study was to investigate the altered driver genes and signal pathways during progression of papillary thyroid cancer (PTC) via next-generation sequencing technology. METHODS: The DNA samples for whole exome sequencing (WES) analyses were extracted from 11 PTC tissues and adjacent normal tissues samples. Direct Sanger sequencing was applied to validate the identified mutations. RESULTS: Among the 11 pairs of tissues specimens, 299 single nucleotide variants (SNVs) in 75 genes were identified. The most common pattern of base pair substitutions was T:A>C:G (49.83%), followed by C:G>T:A (18.06%) and C:G>G:C (15.05%). The altered genes were mainly implicated in MAPK (mitogen-activated protein kinase), PPAR (peroxisome proliferator-activated receptors), and p53 signaling pathways. In addition, 12 novel identified driver genes were validated by Sanger sequencing. The mutations of FAM133A, DPCR1, JAK1, C10orf10, EPB41L3, GPRASP1 and IWS1 exhibited in multiple PTC cases. Furthermore, the PTC cases exhibited individual mutational signature, even the same gene might present different mutational status in different cases. CONCLUSION: Multiple PTC related somatic mutations and signal pathways are identified via WES and Sanger sequencing methods. The novel identified mutations in genes such as FAM133A, DPCR1, and JAK1 may be potential therapeutic targets for PTC patients. PMID- 30278445 TI - Gq-Induced Apoptosis is Mediated by AKT Inhibition That Leads to PKC-Induced JNK Activation. AB - BACKGROUND/AIMS: Gq protein-coupled receptors (GqPCRs) regulate various cellular processes including mainly proliferation and differentiation. In a previous study, we found that in prostate cancer cells, the GqPCR of GnRH induces apoptosis by reducing the PKC-dependent AKT activity and elevating JNK phosphorylation. Since it was thought that GqPCR induces mainly activation of AKT, we undertook to examine how general is this phenomenon and understand its signaling. METHODS: We used various cells to follow the phosphorylation of signaling components using western blotting. RESULTS: In a screen of 21 cell lines, we found that PKC activation results in the reduction of AKT activity, which correlates nicely to JNK activation and in some cases to apoptosis. To further understand the signaling pathways involved in this stimulation, we studied in detail the SVOG-4O and alphaT3-1 cells. We found that PGF2alpha and GnRH agonist (GnRH-a) indeed induce significant Gq- and PKC- dependent apoptosis in these cells. This is mediated by two signaling branches downstream of PKC, which converge at the level of MLK3 upstream of JNK. One branch consists on c-Src activation of the JNK cascade and the second involves reduction of AKT activity that alleviates its inhibitory effect on MLK3, to allow the flow of the c-Src signal to JNK. At the MAPKK level, we found that the signal is transmitted by MKK7 and not MKK4. CONCLUSION: Our results present a general mechanism that mediates a GqPCR-induced, death receptors-independent, apoptosis in physiological, as well as cancer-related systems. PMID- 30278446 TI - Circular RNA Expression in the Brain of a Neonatal Rat Model of Periventricular White Matter Damage. AB - BACKGROUND/AIMS: Periventricular white matter damage (PWMD) is the predominant neurologic lesion in preterm infants who survive brain injury. In this study, we assessed the global changes in and characteristics of the transcriptome of circular RNAs (circRNAs) in the brain tissues of rats with PWMD. METHODS: We compared the expression profiles of circRNAs in brain samples from three rats with PWMD and three paired control tissues using deep RNA sequencing. Bioinformatics analysis was applied to investigate these differentially expressed circRNAs, and quantitative reverse-transcription polymerase chain reaction (qRT PCR) analysis was performed to confirm the results. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed to predict associated cell signaling pathways and functions. Network analysis was performed to predict circRNAs-microRNAs, and target genes related to PWMD. RESULTS: A total of 2151 more reliable circRNAs were dysregulated in the brain tissues of rats with PWMD, indicating a potential role in the condition. Of the 98 circRNAs significantly differentially expressed in rat brains with PWMD (P< 0.05), 52 were significantly over-expressed and 46 were significantly under-expressed. The expression profiles of seven of 10 randomly selected circRNAs were confirmed by qRT-PCR analysis. The glutamatergic synapse pathway and the VEGF signaling pathway, both associated with hypoxia/ischemia induced brain damage, were inriched. Relationship between miRNA (rno-miR-433-3p and rno-miR-206-3p) and HIF 1alpha were evident and potential associations between chr6: 48820833|48857932 and their target genes (rno-miR-433-3p and rno-miR-206-3p) were identified. CONCLUSION: The distinct expression patterns of circRNAs in the brain tissues of rats with PWMD suggest that circRNAs actively respond to hypoxia-ischemia. These findings could assist the development of novel diagnostic and therapeutic targets for PWMD therapy. PMID- 30278447 TI - Characteristics of Lung Cancer in Patients Younger than 40 Years: A Prospective Multicenter Analysis in France. AB - OBJECTIVES: The aim of this study was to describe the demographic and clinico pathological characteristics of lung cancer in patients younger than 40 years. MATERIALS AND METHODS: This was a prospective study performed within the Groupe Francais de Pneumo-Cancerologie. Consecutive patients diagnosed with lung cancer before the age of 40 years were eligible. Data on demographics, medical history, clinico-pathological characteristics, treatment and overall survival were analysed. RESULTS: In total, 146 patients were included from January 2011 to December 2013. Median age was 38 years (IQR: 34-40). Women accounted for 41%. Main histological type was adenocarcinoma (77%). Only 3% had a prior history of cancer, but a family history (first- or second-degree relatives) of cancer was reported in 80 (55%) patients; 85 and 50% were current or past smokers of tobacco and cannabis, respectively; 82% had stage IIIB/IV at diagnosis. Median overall survival was 15.3 (95% CI: 8.1-24.0) months in the whole population, 10.3 (95% CI: 12.5-14.2) months in stage IV and 15 (95% CI: 8.7-35.2) months in stage III. One- and two-year overall survival rates were 57% (95 CI: 49-65) and 31.5% (95 CI: 27-43), respectively. Compared to smokers, non-smokers were significantly younger and more often females. Median overall survival was not statistically different between smokers and non-smokers. PMID- 30278448 TI - Deletions in SERPING1 Lead to Lower C1 Inhibitor Function: Lower C1 Inhibitor Function Can Predict Disease Severity. AB - BACKGROUND: How genotype affects phenotype in hereditary angioedema with C1 inhibitor deficiency (C1-INH-HAE) has not been totally clarified. In this study, we investigated the relationship between different types of mutations and various phenotypic characteristics. METHODS: Clinical data from 81 patients from 47 families were recorded. Complement proteins were analyzed from 61 untreated patients. The coding exons and the exon-intron boundaries of the SERPING1 gene were sequenced, and deletion/duplication analysis with multiple ligation dependent probe amplification was performed. The relationship of complement protein with the mutation type was analyzed by using generalized estimating equations. RESULTS: Thirty-five different mutations (15 novel and 2/15 homozygous) were identified. There was no causative mutation in 6 patients (7.4%). Patients with deletion and large deletion had the lowest (5.05%, 0-18.7; 5.8%, 0-16.5%, respectively), and the none mutation group had the highest C1 inhibitor function (23.3%, 11-78%, p < 0.001). C1 inhibitor function levels decreased as the age of the disease progressed (r = -0.352, p = 0.005). Lower C1 inhibitor function levels caused severer disease (r = -0.404, p = 0.001) and more frequent annual attacks (r = -0.289, p = 0.024). In the off-attack period, C1q levels were lower than normal in 9.8% of the patients. CONCLUSION: Deletion mutations may represent the most unfavorable effect on C1 inhibitor function. The earlier disease onset age could be a sign for lower C1 inhibitor function levels in adult life. C1q levels could also be low in C1-INH-HAE patients, as in acquired angioedema. Lower C1 inhibitor function can predict disease severity and may have negative impacts on the course of C1-INH-HAE. PMID- 30278449 TI - miR-449a Suppresses Tamoxifen Resistance in Human Breast Cancer Cells by Targeting ADAM22. AB - BACKGROUND/AIMS: Most of estrogen receptor positive breast cancer patients respond well initially to endocrine therapies, but often develop resistance during treatment with selective estrogen receptor modulators (SERMs) such as tamoxifen. Altered expression and functions of microRNAs (miRNAs) have been reportedly associated with tamoxifen resistance. Thus, it is necessary to further elucidate the function and mechanism of miRNAs in tamoxifen resistance. METHODS: Tamoxifen sensitivity was validated by using Cell Counting Kit-8 in tamoxifen sensitive breast cancer cells (MCF-7, T47D) and tamoxifen-resistant cells (MCF 7/TAM, T47D/ TAM). Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to detect the expression level of miR-449a in tamoxifen-sensitive/ resistant cells and patient serums. Dual-luciferase assay was used to identify the binding of miR-449a and predicted gene ADAM22. The expression level of ADAM22 was determined by qRT-PCR and western blotting in miR-449a +/- breast cancer cells. Subsequently, rescue experiments were carried out to identify the function of ADAM22 in miR-449a-reduced tamoxifen resistance. Finally, Gene ontology (GO) and Protein-protein interaction analyses were performed to evaluate the potential mechanisms of ADAM22 in regulating tamoxifen resistance. RESULTS: MiR-449a levels were downregulated significantly in tamoxifen-resistant breast cancer cells when compared with their parental cells, as well as in clinical breast cancer serum samples. Overexpression of miR-449a re-sensitized the tamoxifen-resistant breast cancer cells, while inhibition of miR-449a conferred tamoxifen resistance in parental cells. Luciferase assay identified ADAM22 as a direct target gene of miR 449a. Additionally, silencing of ADAM22 could reverse tamoxifen resistance induced by miR-449a inhibition in ER-positive breast cancer cells. GO analysis results showed ADAM22 was mainly enriched in the biological processes of cell adhesion, cell differentiation, gliogenesis and so on. Protein-protein interaction analyses appeared that ADAM22 might regulate tamoxifen resistance through PPARG, LGI1, KRAS and LYN. CONCLUSION: Decreased miR-449a causes the upregulation of ADAM22, which induces tamoxifen resistance of breast cancer cells. These results suggest that miR-449a, functioning by targeting ADAM22, contributes to the mechanisms underlying breast cancer endocrine resistance, which may provide a potential therapeutic strategy in ER-positive breast cancers. PMID- 30278451 TI - Thermal Response of Epigenetic Genes Informs Turtle Sex Determination with and without Sex Chromosomes. AB - Vertebrate sexual fate can be established by environmental cues (e.g., temperature-dependent sex determination, TSD) or by genetic content (genotypic sex determination, GSD). While methylation is implicated in TSD, the influence of broader epigenetic processes in sexual development remains obscure. Here, we investigated for the first time the embryonic gonadal expression of the genome wide epigenetic machinery in turtles, including genes and noncoding RNAs (ncRNAs) involved in DNA/histone acetylation, methylation, ubiquitination, phosphorylation, and RNAi. This machinery was active and differentially thermosensitive in TSD versus GSD (ZZ/ZW) turtles. Methylation and histone acetylation genes responded the strongest. The results suggest these working hypotheses: (i) TSD might be mediated by epigenetically controlled hormonal pathways (via acetylation, methylation, and ncRNAs), or by (ii) hormonally controlled epigenetic processes, and (iii) key epigenetic events prior to the canonical thermosensitive period may explain differences between TSD and GSD. Novel epigenetic candidate regulators other than methylation were identified, including previously unknown ncRNAs that could potentially mediate gonadogenesis. These findings illuminate the molecular ecology of reptilian sex determination and permitted hypothesis building to help guide future functional studies on the epigenetic transduction of external cues in TSD versus GSD systems. PMID- 30278450 TI - MARCH9 Suppresses Lung Adenocarcinoma Progression by Downregulating ICAM-1. AB - BACKGROUND/AIMS: To investigate the clinical significance and functional mechanisms of membrane-associated RING-CH protein 9 (MARCH9) in lung adenocarcinoma (LAC). METHODS: Immunohistochemistry staining was performed to explore the expression of MARCH9 in LAC tissues and adjacent normal lung tissues. Patients' prognosis was evaluated using overall survival. The prognostic role of MARCH9 was tested with univariate and multivariate analyses. To confirm the effect of MARCH9 in cell proliferation and invasion, overexpression of MARCH9 was induced in two LAC cell lines. Cell cycle, apoptosis, migration, invasion, and immunoprecipitation experiments were performed to further explore the signaling pathways involved. RESULTS: Analysis of a series of 143 clinical samples revealed that MARCH9 was down-regulated in tumor tissues compared with normal lung tissues, and this was closely associated with lymph node metastasis (P = 0.004). Univariate and multivariate analyses indicated that MARCH9 was an independent prognostic biomarker for LAC; low MARCH9 expression indicated poor overall survival. Cellular studies with A549 and H1299 cells demonstrated that MARCH9 can attenuate tumor migration and invasion but had little effect on cell cycle or apoptosis. Moreover, an interaction between MARCH9 and ICAM-1 protein was identified, and overexpression of MARCH9 was found to attenuate the oncogenic effect of ICAM-1, suggesting that MARCH9 may inhibit tumor progression by downregulating ICAM-1 signaling. CONCLUSION: MARCH9 downregulation in LAC tissues correlated with poor clinical outcomes. MARCH9 may serve as a novel biomarker and potential therapeutic target for LAC.

AB - BACKGROUND/AIMS: Hepatocellular carcinoma (HCC) has a high morbidity as well as mortality and is believed to be one of the most prevalent cancers worldwide. The long non-coding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is involved in numerous cancers, including HCC. This study aimed to explore the role of MALAT1 in HCC progression. METHODS: The expression levels of MALAT1 and Vimentin in HCC tissues and relative pair-matched adjacent normal liver tissues were analyzed by RT-PCR, and immunohistochemistry. Using bioinformatics analysis and dual-luciferase assay, we examined the correlation between MALAT1 and miR-30a-5p. Dual-luciferase assay and western blotting suggested that Vimentin was a target of miR-30a-5p. A wound healing assay and transwell assays were employed to determine the effect of MALAT1 and miR-30a-5p on cell migration and invasion in HCC. RESULTS: Our data demonstrated that the levels of MALAT1 and Vimentin were upregulated in HCC tissues and that miR-30a-5p was a direct target of MALAT1. Silenced MALAT1 and overexpressed miR-30a-5p each inhibited cell migration and invasion. Additionally, dual-luciferase assay and western blotting demonstrated that MALAT1 could competitively sponge miR-30a-5p and thereby regulate Vimentin. CONCLUSION: Our data suggest that MALAT1 acts as an oncogenic lncRNA that promotes HCC migration and invasion. Therefore, the MALAT1-miR-30a-5p-Vimentin axis is a potential therapeutic target and molecular biomarker in HCC.

AB - To reduce the vulnerability of their small body size, common marmosets live in large and cohesive social groups. Thus, we hypothesized that in order to compensate for small body size and predation risk, individuals of common marmosets will stay gathered rather than scattered when foraging for eggs and/or nestling birds. Furthermore, in order to avoid costly injuries and eventual predation risks, for both sides, the majority of interactions among common marmosets and small birds will not involve direct physical contact. The study was developed in a small fragment of Atlantic Forest in the northeast of Brazil. We recorded a total of 115 interactions between common marmosets (Callithrix jacchus) with 7 different bird species. As expected, agonistic interactions were significantly more frequent when the marmosets were gathered. Also, most agonistic interactions by the birds toward common marmosets involved overflights without physical contact. Apparently, the set of avoidance behavior leads to a reduced predation risk for both sides. It appears that dispersed marmosets do not represent an imminent threat that justifies an agonistic reaction by the birds as the latter appear to avoid exposing themselves to unnecessary danger during agonistic interactions, especially when the marmosets are gathered. PMID- 30278453 TI - Hepatitis E Virus Genotype 3 Genomes from RNA-Positive but Serologically Negative Plasma Donors Have CUG as the Start Codon for ORF3. AB - Hepatitis E virus (HEV) is a pathogen that causes hepatitis worldwide. Molecular studies have identified HEV RNA in blood products although its significance is not understood. This study was undertaken to characterize HEV genomes in asymptomatic plasma donors from Sweden and Germany lacking anti-HEV. Complete open reading frames (ORFs) were obtained from HEV strains in 5 out of 18 plasma donors who tested positive for HEV RNA. All strains had CUG as the start codon of ORF3, while 147 GenBank strains all had AUG as the start codon (p < 0.0001). This substitution was found in both interrelated and unrelated strains belonging to different phylogenetic clades. The HEV strains from the seronegative plasma donors had no other substitution in common, which may be why the CUG substitution seems to explain the seronegativity. PMID- 30278455 TI - Hepatitis E Virus Genotype 1 and Hepatitis A Virus Dual Infection in Pediatric Patients with a Low Socioeconomic Status from Mexico. AB - OBJECTIVE: We aimed to detect and characterize hepatitis E virus (HEV) RNA in sera samples from a pediatric population infected with the hepatitis A virus (HAV) exhibiting acute hepatitis and to correlate the infection status with the clinical outcome. METHODS: Seventy-five ELISA-positive samples from children containing anti-HAV and anti-HEV IgM were used to amplify and characterize partial regions within HEV ORF2. A statistical comparison of clinical data between HEV IgM-positive/HEV RNA-positive patients and HEV IgM-positive/HEV RNA negative patients was performed. RESULTS: Thirteen out of 75 IgM-positive samples provided amplification of discrete regions of the HEV genome. Nested RT-PCR-based detection and subsequent sequencing of 5 samples confirmed the identity of HEV genotype 1 (G1), which had not been previously reported in Mexico. Though not significant, a trend towards exacerbated clinical manifestations was found in HEV RNA-positive patients relative to HEV RNA-negative patients. CONCLUSIONS: An elevated rate of G1 RNA was detected. Hepatitis E seems to be a neglected disease in Mexico and epidemic strains of HEV are likely to play a role as causative agents of acute hepatitis in highly exposed children. Although HAV is endemic in Mexico, an HEV-RNA detection rate of 17% in co-infected samples shows the need for screening for HEV as a part of future vaccination strategies. PMID- 30278456 TI - Schema Modes and Personality Disorder Symptoms in Alcohol-Dependent and Cocaine Dependent Patients. AB - Substance use disorders (SUD) and personality disorders co-occur frequently. This relationship might be understood by studying schema modes (a key concept in Schema therapy), which explain the dysfunctions characterizing personality disorder patients. In the present study, we compared the schema modes and personality disorder symptoms between alcohol-dependent patients, cocaine dependent patients and healthy controls. We found indications that specific schema modes are specific for SUD patients. However, no differences between specific subtypes of SUD patients (alcohol- vs. cocaine-dependent patients) could be found regarding schema modes. Further, it is suggested that borderline personality disorder symptoms are highly relevant for SUD patients. A first step is made in understanding the relationship between schema modes and SUD, which may contribute to the understanding of the problematic behaviour seen in patients with personality disorders and SUD (and may possibly contribute to the improvement of the treatment of this group of patients). PMID- 30278457 TI - Effect of Fluoride Toothpaste Containing Nano-Sized Sodium Hexametaphosphate on Enamel Remineralization: An in situ Study. AB - OBJECTIVE: To evaluate the remineralizing potential of a conventional toothpaste (1,100 ppm F) supplemented with nano-sized sodium hexametaphosphate (HMPnano) in artificial caries lesions in situ. DESIGN: This double-blinded crossed study was performed in 4 phases of 3 days each. Twelve subjects used palatal appliances containing 4 bovine enamel blocks with artificial caries lesions. Volunteers were randomly assigned into the following treatment groups: no F/HMP/HMPnano (Placebo); 1,100 ppm F (1100F); 1100F plus 0.5% micrometric HMP (1100F/HMP) and 1100F plus 0.5% nano-sized HMP (1100F/HMPnano). Volunteers were instructed to brush their natural teeth with the palatal appliances in the mouth for 1 min (3 times/day), so that blocks were treated with natural slurries of toothpastes. After each phase, surface hardness post-remineralization (SH2), integrated recovery of subsurface hardness (DeltaIHR), integrated mineral recovery (DeltaIMR) and enamel F concentration were determined. Data were submitted to analysis of variance and Student-Newman-Keuls' test (p < 0.001). RESULTS: Enamel surface became 42% harder when treated with 1100F/HMPnano in comparison with 1100F (p < 0.001). Treatment with 1100F/HMP and 1100F/HMPnano promoted an increase of ~23 and ~87%, respectively, in DeltaIHR when compared to 1100F (p < 0.001). In addition, DeltaIMR for the 1100F/HMPnano was ~75 and ~33% higher when compared to 1100F and 1100F/HMP respectively (p < 0.001). Enamel F uptake was similar among all groups except for the placebo (p < 0.001). CONCLUSION: The addition of 0.5% HMPnano to a conventional fluoride toothpaste was able to promote an additional remineralizing effect of artificial caries lesions. PMID- 30278459 TI - Comparison of Bubble CPAP Devices Using RAM Cannula for Extubation Failure in Very Low Birth Weight Infants: Randomized and Cohort Studies. AB - INTRODUCTION: Bubble continuous positive airway pressure (bCPAP) generates a variable pressure due to bubble size and frequency, and these pressure oscillations may contribute to lung recruitment and gas exchange. Single-outlet bCPAP devices generate larger pressure fluctuation than bCPAP devices with diffusers, but clinical efficacy is unclear. Our hypothesis was that a single outlet bCPAP device (B&B Bubbler(c)) would decrease extubation failure and improve oxygenation compared with a bCPAP device with a diffuser (BabiPlus(c)). METHODS: Bench testing of bCPAP devices with the RAM(c) cannula determined pressure averages, fluctuations, and CPAP transmission at prongs. The B&B Bubbler(c) and the BabiPlus(c) devices were compared for oxygenation and bCPAP failure within 72 h of extubation in a randomized trial in infants less than 1,250 g (n = 43). Additionally, a cohort study with infants extubated to BabiPlus(c) (n = 128), B&B Bubbler(c) (n = 119), and noninvasive positive pressure ventilation (NIPPV) (n = 107) were compared. RESULTS: Small differences in pressure fluctuations between bCPAP devices are attenuated by the RAM(c) cannula. Pressures at RAM(c) prongs are 62% of set pressure. The bCPAP extubation failure rate (35%) and oxygenation were similar between the bCPAP devices. bCPAP success was associated with lower FiO2 at extubation and decreased need for additional FiO2 in both groups. In the setting of the RAM(c) cannula, there were no differences in extubation failure rate for infants extubated to bCPAP or NIPPV. CONCLUSIONS: There were no clinical differences at extubation between the B&B Bubbler(c) and BabiPlus(c) devices. Oxygenation may predict bCPAP failure. The use of the RAM(c) cannula as a bCPAP interface should be more closely examined. PMID- 30278458 TI - Total Saponins of Aralia Elata (Miq) Seem Alleviate Calcium Homeostasis Imbalance and Endoplasmic Reticulum Stress-Related Apoptosis Induced by Myocardial Ischemia/Reperfusion Injury. AB - BACKGROUND/AIMS: Total saponins of Aralia elata (Miq) Seem (AS) from the Chinese traditional herb Long ya Aralia chinensis L. reportedly provide cardioprotective effects, but the exact mechanisms require further study. Previous studies have showed that myocardial ischemia/ reperfusion injury (MIRI) was related to calcium homeostasis imbalance and endoplasmic reticulum stress (ERS). Thus, this study aimed to demonstrate protective effects of AS on MIRI. METHODS: After administrating AS for 5 days, the left anterior descending artery coronary artery of Sprague-Dawley (SD) rats was ligated for 30 min. After 48 h of reperfusion, haemodynamics, Evans blue/ 2,3,5-triphenyltetrazolium chloride (TTC) staining, hematoxylin-eosin (HE) staining, masson staining and the levels of lactate dehydrogenase (LDH) and creatine kinase (CK), superoxide dismutase (SOD), malondialdehyde (MDA) were detected to assess MIRI. ATPase activity and Western Blot were used to study the mechanisms. RESULTS: Compared with IR group, AS treatment groups could significantly reduce myocardial infarct size; improve myocardial pathologic progress; decrease content of LDH, CK, and MDA; increase content of SOD; and restore the activities of Ca2+-Mg2+-ATPase, Na+-K+-ATPase, sarcoplasmic reticulum Ca2+-ATPases (SERCA), and calcineurin (CaN). AS treatment groups also significantly up-regulated the expression of GRP78, C/EBP homologous protein (CHOP), and Bax, and down-regulated the expression of Bcl-2, all similar to the effects of ERS. CONCLUSION: These findings illustrated that AS could prevent myocardial ischemia/reperfusion injury and reduce calcium homeostasis imbalance and ERS-related apoptosis. PMID- 30278460 TI - A New Transcutaneous Method for Breast Cancer Detection with Dogs. AB - We developed a new transcutaneous method for breast cancer detection with dogs: 2 dogs were trained to sniff skin secretion samples on compresses that had been worn overnight by women on their breast, and to recognize a breast cancer sample among 4 samples. During the test, the dogs recognized 90.3% of skin secretion breast cancer samples. This proof-of-concept study opens new avenues for the development of a reliable cancer diagnostic tool integrating olfactory abilities of dogs. PMID- 30278462 TI - Effect of Delayed Cord Clamping of Term Babies on Neurodevelopment at 12 Months: A Randomized Controlled Trial. AB - BACKGROUND: Delayed cord clamping (DCC) is associated with an improved iron status at 8 months, a reduction of anemia at 12 months, and an improved development at 4 years. Assessment of the development after DCC has not been performed earlier in a setting with a high prevalence of iron deficiency. OBJECTIVE: The aim of this paper was to investigate the effects of DCC compared to early cord clamping (ECC) on the development evaluated with the Ages and Stages Questionnaire (ASQ) at 12 months of age. METHOD: We conducted a randomized controlled trial investigating the effect of DCC (>=180 s) versus ECC (<=60 s) in 540 full-term deliveries. Twelve months after delivery, the parents reported their infant's development by ASQ. Infants having a score < 1 standard deviation (SD) under the mean score were considered "at risk" of affected neurodevelopment. RESULTS: At 12 months of age, 332 (61.5%) infants were assessed. Fewer children in the DCC group were "at risk" of having affected neurodevelopment measured by the ASQ total score, 21 (7.8%) versus 49 (18.1%) in the ECC group. The relative risk was 0.43 (0.26-0.71). Infants in the DCC group had higher mean total scores (SD), 290.4 (10.4) versus 287.2 (10.1), p = 0.01. Significantly fewer infants in the delayed group were "at risk" and had higher scores in the domains "communication", "gross motor", and "personal-social". CONCLUSIONS: DCC after 3 min was associated with an improvement of the overall neurodevelopment assessed at 12 months of age as compared to infants in the group with cord clamping within 1 min. PMID- 30278461 TI - Mining Prognostic Significance of MEG3 in Human Breast Cancer Using Bioinformatics Analysis. AB - BACKGROUND/AIMS: Maternally expressed gene 3 (MEG3) is an imprinted gene with maternal expression, which may function as a tumor suppressor by inhibiting angiogenesis. To identify the prognostic value of MEG3 in breast cancer, systematic analysis was performed in this study. METHODS: To evaluate gene alteration during breast carcinogenesis, we explored MEG3 expression using the Serial Analysis of Gene Expression Genie suite and Oncomine analysis. The prognostic roles of MEG3 in breast cancer were investigated using the PrognoScan database. The heat map and methylation status of MEG3 were determined using the UCSC Genome Browser. RESULTS: We found that MEG3 was more frequently downregulated in breast cancer than in normal tissues and this correlated with prognosis. However, estrogen receptor and progesterone receptor status were found to be positively correlated with MEG3 expression. Conversely, basal-like status, triple-negative breast cancer status, and Scarff Bloom & Richardson grade criterion were negatively correlated with MEG3 expression. Following data mining in multiple big data databases, we confirmed a positive correlation between MEG3 and heparan sulfate proteoglycan 2 (HSPG2) expression in breast cancer tissues. CONCLUSION: MEG3 could be adopted as a marker to predict the prognosis of breast cancer with HSPG2. However, large-scale and comprehensive research is needed to clarify our results. PMID- 30278463 TI - Anaesthesia and Perioperative Care for Transoral Robotic Surgery. AB - Minimally invasive surgical techniques have gained increasing interest in recent years for their conferred recovery and postoperative advantages. Robot-assisted surgery requires special consideration for anaesthetic and perioperative management. The introduction of robot- assisted intra-oral surgery has important implications on anaesthesia provision, airway management and patient safety. Due to its relatively novel use we explore these considerations alongside our own experience in this field. PMID- 30278464 TI - The Effect of LncRNA H19/miR-194-5p Axis on the Epithelial-Mesenchymal Transition of Colorectal Adenocarcinoma. AB - BACKGROUND/AIMS: Since the combined actions of lncRNAs and miRNAs have been considered to be involved in the occurrence and development of various neoplasms, the main purpose of this study was to discover whether and how lncRNA H19 and miR 194 influenced the epithelial-mesenchymal transition (EMT) process of colorectal adenocarcinoma (CRA). METHODS: Totally 214 pairs of CRA and adjacent normal tissues were collected, and 5 human CRA cell lines (i.e. HCT116, HT-29, RKO SW280 and Lovo) were purchased. Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was adopted to quantify the H19 and miR-194-5p expressions in cells and tissues. The expressions of FoxM1, E-cadherin, vimentin, N-cadherin were determined using western blot. On the side, si-H19, si-NC, miR-194-5p mimic, miR-194-5p inhibitor and negative control (NC) were transfected into CRA cell lines. Meanwhile, the invasive, migratory and proliferative conditions of the cells were assessed through transwell, wound healing and colony-forming experiments, with final verification of the relationship between H19 and miR-194 5p employing dual-luciferase reporter gene assay. RESULTS: Highly-expressed H19, lowly-expressed miR-194-5p, low-grade differentiation and lymph node metastasis appeared as the independent predictors of unfavorable prognosis in CRA patients' (all P< 0.05). It indicated that FoxM1 expression displayed positive correlations with H19 expression, yet negative associations with miR-194-5p expression within CRA tissues (P< 0.05). In addition, transfection of H19-siRNA and miR-145-5p mimic triggered a conspicuous increase in E-cadherin expression, as well as an evidently down-regulation in vimentin and N-cadherin expressions within HT29 and RKO cells (P< 0.05). On the other hand, the invasive and migratory capacities of CRA cells were significantly hindered (P< 0.05). Moreover, the luciferase reporter gene assay confirmed that H19 modified miR-194-5p expression through directly targeting at it (P< 0.05). Ultimately, FoxM1 could reverse the role of miR-194-5p in inhibiting invasion, migration and EMT of CRA cells (P< 0.05). CONCLUSION: LncRNA H19/miR-194/FoxM1 axis could serve as a profound target for the diagnosis and treatment of CRA. PMID- 30278465 TI - The Novel Effect of Immunomodulator-Glatiramer Acetate on Epileptogenesis and Epileptic Seizures. AB - BACKGROUND/AIMS: Immunological mechanisms can be triggered as a response to central nervous system insults and can lead to seizures. In this study an investigation was made to determine if glatiramer acetate (GA), an immunomodulator currently used in the treatment of multiple sclerosis, could protect rats from pilocarpine-induced seizures and chronic epilepsy. METHODS: Two groups of adult male Sprague-Dawley rats, experimental (GA) and control, were used in the study. The systemic IL-1alpha and IL-1beta levels at baseline were checked as well as status epilepticus (SE), and the spontaneous recurrent seizure (SRS) stage by enzyme-linked immunosorbent assay. The GA group was given GA (150 MUg/kg, ip) and the control group was given a saline injection prior to pilocarpine-induced seizures. Seizure susceptibility, severity and mortality were evaluated, using Racine seizure classification and hippocampal damage was evaluated by Nissl staining. The GA group received GA (150 MUg/kg/day, ip) daily after SE, and the chronic spontaneous seizures were evaluated by long-term video recording, and mossy fiber sprouting was evaluated by Timm staining. The IL 1alpha and IL-1beta levels were correlated with seizure activities. The TNF-alpha level in the hippocampus was determined at the SRS stage by immunohistochemistry. The effect of GA on ionic currents and action potentials (APs) in NG108-15 differentiated neurons was investigated using patch-clamp technology. RESULTS: It was found that latency to severe seizures was significantly longer in the GA (p < 0.01) group, which also had SE of shorter duration and less frequent SRS (p < 0.01). GA attenuated acute hippocampal neuron loss and chronic mossy fiber sprouting in the CA3 and the SRS-reduction correlated with the reduction of IL 1alpha, but not with IL-1beta or TNF-alpha levels. Mechanistically, GA reduced the peak amplitude of voltage-gated Na+ current (INa), with a negative shift in the inactivation curve of INa and reduced the amplitude of APs along with decreased firing of APs. CONCLUSION: GA might serve as a neuroexcitability modulator which attenuates pilocarpine-induced acute and chronic excitotoxicity. Sodium channel attenuation was partially independent of the immunomodulatory effect. PMID- 30278466 TI - Prognostic Role of High Stathmin 1 Expression in Patients with Solid Tumors: Evidence from a Meta-Analysis. AB - BACKGROUND/AIMS: Several recent studies have demonstrated that Stathmin 1expression may be closely associated with prognosis in patients with various types of cancers. In the present study, we conducted a meta-analysis of all available studies in the English literature to assess the prognostic value of Stathmin 1expression in patients with solid cancers. METHODS: The online databases PubMed, Embase, and Web of Science were searched for literature regarding Stathmin 1 and its association with patient outcomes associated with solid cancers. RESULTS: A total of 23 articles including 26 studies that contained 5 335 patients were retrieved and analyzed. Our results indicated that high Stathmin 1 expression yielded a worse overall survival (OS) (hazard ratio [HR] = 2.17, 95% confidence interval [CI]: 1.81-2.60), disease-free survival (DFS) (HR = 2.46, 95% CI: 2.00-3.02), disease-specific survival (DSS) (HR = 1.98, 95% CI: 1.58- 2.47) and progression-free survival (PFS)/recurrence-free survival (RFS) (HR = 2.09, 95% CI: 1.51-2.89). Furthermore, the association of high Stathmin 1 expression with poor survival was significant even for sub-group analyses of different tumor types, ethnicities, methods used to calculate HRs, detected methods, and analysis types. CONCLUSION: In summary, this meta-analysis determined that high Stathmin 1 expression is associated with poor prognosis in patients with solid cancers and expression of this protein could be a clinically useful prognostic biomarker. PMID- 30278467 TI - Resistance to Fas-Mediated Apoptosis Does Not Correlate to Structural Alterations or Expression Changes of the Death Receptor in Papillary Thyroid Carcinomas. AB - BACKGROUND: Malignant cells exhibit significant resistance to FAS-mediated cell death, through different processes, including FAS mutations, soluble FAS expression, or FAS transcriptional dysregulation by P53, eventually escaping from immune surveillance. Since thyroid carcinomas were shown to be resistant to FAS mediated apoptosis, we investigated the above mechanisms in thyroid carcinoma samples. METHODS: Thirty-seven thyroid carcinoma samples were analyzed for mutations in FAS exon 9 and TP53 exons 5-8 and protein expression by means of immunohistochemistry. Moreover, thyroid carcinoma mRNA samples were subjected to reverse transcription - PCR, to evaluate the relative expression of transmembrane FAS versus its soluble form. RESULTS: Analysis revealed indications for TP53 mutations in the anaplastic carcinomas, but not in the other thyroid specimens examined for TP53 or FAS exon 9 mutations. FAS receptor expression was observed in almost all thyroid specimens (97%) with significant up-regulation in papillary carcinomas. P53 nuclear staining was observed only in anaplastic carcinomas. Full length FAS mRNA was detected in all specimens examined, with soluble FAS mRNA being either absent or present in very low amounts. CONCLUSIONS: Our results denote that FAS death domain or TP53 DNA-binding domain mutations, down regulation of FAS receptor expression, or expression of FAS soluble isoform are not responsible for the seeming inhibition of FAS-mediated apoptosis in papillary thyroid carcinoma cells. PMID- 30278468 TI - [Externally Acquired Radiological Image Data and Reporting for the Clinical Routine, Conference and Boards - Legal Aspects of the Second Opinion in Germany]. AB - BACKGROUND: Because of an increasing number of boards and conferences, the number of second opinion readings of externally acquired image data is growing dramatically. In this review article we intend to give medical and legal recommendations for the documentation and interpretation of externally acquired radiological data for second opinions and board presentations based on German jurisdiction. METHOD: Using the FAQ format as a dialog between radiologists and medical legal experts, we answer the most crucial questions regarding correct documentation and interpretation for externally acquired radiological image data based on an up-to-date literature search. RESULTS: Based on the unity of radiological image data and the corresponding written report according to the radiation protection law, the primary report should be present when composing a second opinion. If the primary external report is not present, this should be mentioned as a limitation. All radiological second opinions should be documented in written form. This is especially important in cases of discrepant findings. Legally, the attending physician is responsible for selecting the radiological opinion. The radiologist should not rely on the written primary report without personal reevaluation. Legally, it would be considered radiological malpractice if the external image data and previous image data are not evaluated personally. CONCLUSION: From a legal point of view, there are explicit recommendations regarding thorough documentation of a second opinion as an independent medical service in all cases. PMID- 30278470 TI - Catheter-Based Computed Tomography Angiography in Anterolateral Thigh Perforator Mapping of Chinese Patients. AB - BACKGROUND: During reconstructive surgery, anterolateral thigh (ALT) flap harvest is challenging due to variation and uncertainty in perforator distribution. We performed a pilot study to identify the predictive value of catheter-based computed tomography angiography (C-CTA) and traditional CTA (T CTA) in ALT perforator mapping for patients whose ALT perforators were difficult to identify. METHODS: Thirty-four consecutive T-CTA/C-CTA-mapped ALT flaps were evaluated for extremity reconstruction. The perforator location, origin, and course were compared between T-CTA/C-CTA imaging and intraoperative findings. The mapping efficiency of T-CTA and C-CTA was compared thoroughly. RESULTS: Among the 34 ALT thigh flaps, 117 (36) of the 130 perforators identified intraoperatively were visible on C-CTA (T-CTA) in a subgroup of Chinese limb trauma patients with limited activity. C-CTA showed a satisfactory efficiency in perforator mapping, which was much better than the efficiency of T-CTA. C-CTA also showed a much better sensitivity (90.00 vs. 27.69%), specificity (94.74 vs. 66.67%), and accuracy (91.07 vs. 36.69%), and a much lower false-positive (1.68 vs. 26.53%), and false-negative rate (10.00 vs. 72.31%). Moreover, C-CTA could accurately predict the origin and septocutaneous or intramuscular course in all identified perforators. All flaps were elevated successfully and survived. CONCLUSIONS: C-CTA outperforms T-CTA in the preoperative perforator mapping of ALT flaps in a subgroup of Chinese limb trauma patients. C-CTA should be the method of choice for perforator mapping in patients whose ALT flaps are intended for extremity reconstruction. PMID- 30278471 TI - Inpatient Rehabilitation for Children and Adolescents With Diabetes in Germany Between 2006 and 2013. AB - INTRODUCTION: In Germany, inpatient rehabilitation is a well-established additive option in the therapeutic concept for children and adolescents with diabetes. However, its contribution in pediatric diabetes care is not known exactly. Our objective was to analyze inpatient rehabilitation in pediatric diabetes over eight years in Germany. METHODS: We requested secondary data from the German Statutory Pension Insurance Scheme to evaluate all completed inpatient rehabilitations for children and adolescents with diabetes (ICD-code E10-14) reimbursed by this institution between 2006 and 2013. For each type of diabetes, we analyzed the distribution of admissions by year, age-group, sex, nationality, and other documented diagnoses. All analyses were conducted via remote computing with IBM SPSS Version 24. RESULTS: Between 2006 and 2013, 5,403 admissions to inpatient rehabilitation for 4,746 children and adolescents with diabetes were documented. For type 1 diabetes (T1D; 88.5% of admissions), the number of yearly admissions increased from 458 in 2006 to 688 in 2013 (p=0.013), especially for age-group>5-10. The increase for type 2 diabetes (T2D) was not significant. Admissions were more frequent for girls (53.6%, p<=0.001), age>10-15 years (42.8%, p=0.001), and German nationality (98.5%). Obesity (T1D: 11.1%; T2D: 87.9%) and mental disorders (T1D: 11.6%; T2D: 27.4%) were the most frequent documented diagnoses in addition to diabetes. CONCLUSION: This study provides a comprehensive overview of inpatient rehabilitation for children and adolescents with diabetes over many years in Germany. Until 2013, inpatient rehabilitation remained important in pediatric diabetes care, especially for children with mental disorders or obesity. PMID- 30278469 TI - [Regulation of bone metabolism by the Wnt signaling pathway]. AB - The development and homeostasis of multicellular organisms depends on a complex cellular interaction between proliferation, migration, differentiation, adhesion, and cell death. Wnt signaling pathways coordinate these different cellular responses. Wnt signaling plays a role as a regulatory pathway in the osteogenic differentiation of mesenchymal stem cells. The Wnt signaling pathway is an attractive therapeutic target with the potential to directly modulate stem cells responsible for the regeneration of skeletal tissue. Recent studies indicate that Wnt ligands are capable of promoting bone growth, suggesting that Wnt factors could be used to stimulate bone healing in osteogenic disorders. PMID- 30278472 TI - alpha-Glucosidase Inhibitory and Anti-Inflammatory Coumestans from the Roots of Dolichos trilobus. AB - Four new coumestans dolichosins A - D (1: -4: ) were isolated from the roots of Dolichos trilobus, together with four known compounds: isosojagol (5: ), phaseol (6: ), psoralidin (7: ), and 4",5"-dehydroisopsoralidin (8: ). Their structures were elucidated on the basis of spectroscopic data interpretation, mass spectrometric analyses, and the comparison with literature data of related compounds. The anti-inflammatory activity of these compounds (1: -8: ) was evaluated through the inhibition of nitric oxide production in lipopolysaccharide activated murine macrophage RAW 264.7 cells, in which compounds 1: and 6: displayed moderate inhibitory activity and no cytotoxic effects. In a alpha glucosidase inhibitory assay, compounds 1: and 5: -8: exhibited appreciable inhibition on alpha-glucosidase. Especially compounds 1, 7: , and 8: showed IC50 values lower than 20.0 uM.

AB - BACKGROUND: This study evaluates outcomes of mitral valve surgery (MVS), replacement (MVR), and repair (MVr), during concomitant aortic valve replacement (AVR). METHODS: Patients undergoing MVS with concomitant AVR between 2011 and 2017 at a single center were reviewed. Patients were stratified into MVR versus MVr with concomitant AVR. Outcomes included early and midterm mortality, hospital re-admissions, re-operations, and complications. Multivariable Cox regression analysis was used for risk-adjustment. RESULTS: Four hundred twenty-four patients underwent MVS with concomitant AVR: 247 (58.3%) MVr and 177 (41.7%) MVR. In unadjusted analysis, there was a non-significant increase in 30-day mortality with MVR, with no differences in 1- and 5-year mortality (30-day: 5.6% vs 10.1%, P = 0.081; 1-year: 14% vs 18.2%, P = 0.181; 5-year: 35.1% vs 37.8%, P = 0.232). Freedom from re-admission and mitral reoperation were comparable. Freedom from at least moderate mitral regurgitation at 5 years was 78% in MVr patients. Those undergoing MVR had increased postoperative blood transfusions, acute renal failure, and pleural effusions requiring drainage (P each <0.05). CONCLUSIONS: MVr can be performed during concomitant AVR without an adverse impact on longer term outcomes, including mortality, re-admissions, and mitral reoperations. The majority of patients have durable repairs at 5 years although durability is less than that reported in isolated MVS.

AB - BACKGROUND: The diagnostic approaches and therapeutic strategies of atopic dermatitis (AD) are generally inconsistent among physicians and health institutions. OBJECTIVE: To develop a consensus statement among experts to reduce the variations in practice regarding the diagnosis and treatment of patients >= 12 years with AD to improve their care. METHODS: Systematic literature search in PubMed and GREAT. With methodological support and using the Delphi method, a formal consensus was developed among 16 experts in Dermatology and Allergology, based on the current evidence and its applicability in the Mexican context. Apart from intense electronic communication, several issues of disagreement were discussed in two face-to-face meetings. RESULTS: The clinical experts reached consensus on 46 statements related to the definition, classification, diagnostic strategies and treatment of AD. For the diagnosis we suggest the Williams criteria and for severity scoring the SCORAD (by the doctor) and POEM (by the patient). In addition to general care and treatment education (workshops), we suggest four steps for treatment, depending on severity: 1. Topical treatment with anti-inflammatory agents (and systemic: antihistamines/antileukotrienes -low level evidence-) 2. Phototherapy, 3. Cyclosporin A and 4. Dupilumab, with the possibility of managing this biological earlier on if a fast effect is needed. In extrinsic AD we suggest evaluating the addition of allergen immunotherapy or an elimination diet, if there is an IgE-mediated respiratory or food allergy, respectively. CONCLUSION: The panel of experts reached consensus on relevant aspects of AD with a focus on the transcultural adaptation of recent evidence. PMID- 30278479 TI - Assessment of treatment outcomes in patients with advanced hilar cholangiocarcinoma (stages III-IV): Clinical significance of interventional therapy. AB - The clinical significance of palliative interventional therapy in the management of patients with advanced hilar cholangiocarcinoma (HCCA; stages III-IV) has yet to be studied. The present work was aimed to compare the clinical outcomes of the patients treated with surgery or interventional therapy.A total of 90 patients with advanced HCCA, who admitted Fuyang First People's Hospital from May 2015 to February 2016, were enrolled. Forty-five of them were assigned to the experimental group receiving biliary drainage as the interventional therapy, and the remaining 45 patients were designated as the conventional group receiving radical/palliative surgery. Before and after the treatment total bilirubin from blood was measured. The length of treatment and medical cost were also examined. All patients were followed up for at least 1 year after the treatment.For both the experimental and conventional groups, the serum bilirubin levels after treatment were significantly lower than those before treatment (P < .05); however, no significant differences between groups were seen. There were no significant differences between experimental and conventional groups in the incidence of postoperative complications and survival outcomes. Of note, the length of treatment of the experimental group was substantially shorter than that of the conventional group (P < .05). The medical expense of the experimental group was only about one-third of that of the conventional group (P < .05).Although the interventional therapy does not improve patients' survivals and reduce the incidence of complications, it significantly shortens the treatment length, reducing substantially the medical expense. This finding provides new insights into the treatment strategy for patients with advanced HCCA. PMID- 30278480 TI - Biological characteristics of 18F-FDG PET/CT imaging of cerebral alveolar echinococcosis. AB - This study aims to analyze the characteristics of F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) for cerebral alveolar echinococcosis (CAE).Twenty-five CAE patients underwent F-FDG PET/CT, and the diagnosis was confirmed by clinical and surgical pathology. The F-FDG PET/CT results were subject to visual and semiquantitative analysis, and the difference in F-FDG SUVmax for lesions among the 3 types of CAE was evaluated.In the 25 CAE patients, 62 lesions were detected by F-FDG PET/CT, and these lesions were classified into 3 types, according to the characteristics of the lesion's uptake of F-FDG on PET images: type I, 17 lesions, FDG was concentrated into a mass radioactive distribution in the CAE foci; type II, 28 lesions, FDG presented a annular concentrated radioactive distribution around the CAE foci; type III, 17 lesions, FDG in the CAE foci presented a radioactive distribution with defects and sparse areas. The difference in F-FDG SUVmax between type I and type II CAE was not statistically significant (P > .05), the difference in F-FDG SUVmax between type I and type III CAE was statistically significant (P < .001), and the difference in F-FDG SUVmax between type II and type III CAE was statistically significant (P < .001);The F-FDG PET manifestations of CAE are classified into 3 types. Both type I and type II may have invasive activity, while the lesions of type III CAE show that the focus is relatively stable or at a stationary phase. If there are no definite alveolar echinococcus focus in other sites, these patients can temporarily delay the treatment. It is recommended that the patient should undergo whole body PET/CT once a year to dynamically observe the bioactivity and size of type III CAE lesions and assess the presence of new echinococcus lesions in the rest of the body. PMID- 30278481 TI - Feasibility and Efficacy of Transient Elastography using the XL probe to diagnose liver fibrosis and cirrhosis: A meta-analysis. AB - BACKGROUND: Transient elastography (TE) has been validated as an effective noninvasive tool for the assessment of liver fibrosis. The XL probe is a new probe that was initially designed for use in patients with obesity. A meta analysis was performed to assess the feasibility and efficacy of TE using the XL probe. METHODS: In September 2016, we systematically searched the PubMed and Science Direct search engines. The feasibility of TE was evaluated based on the failure rate and the results of the unreliable liver stiffness measurement (LSM). The efficacy of TE was measured using sensitivity, specificity, and summary receiver-operating characteristic as measures/indices assessed in different stages of fibrosis. Heterogeneity was measured using the chi-squared test and the Q-statistic. We used the 95% confidence interval (95% CI) as an effect measure. RESULTS: We included 8 studies in the meta-analysis. When the XL was compared to the M probe, the former showed a lower risk of failure rate [relative risk (RR) 0.24, 95% CI 0.14-0.38]. In patients with a body mass index >=30 kg/m, the XL probe showed a statistically significantly lower risk of failure rate (RR 0.16, 95% CI 0.08-0.32) but no significant improvement (RR 0.76, 95% CI 0.50-1.16) in the unreliable LSM result. In patients showing liver fibrosis stage >=F2, the XL probe showed a sensitivity of 0.56 (95% CI 0.39-0.72), specificity of 0.71 (95% CI 0.61-0.79), and an area under the curve (AUC) of 0.71. The results observed in patients with liver fibrosis stage F4 were more promising with a sensitivity of 0.84 (95% CI 0.76-0.90), specificity of 0.78 (95% CI 0.70-0.84), and an AUC of 0.88. CONCLUSION: TE using the XL probe demonstrates significant diagnostic utility in patients with liver fibrosis and is likely to be more reliable than the M probe in patients with obesity. Large prospective multicenter studies are, however, necessary to establish the new cut-off values to be used for the XL probe in patients with obesity. PMID- 30278482 TI - DHCR24 predicts poor clinicopathological features of patients with bladder cancer: A STROBE-compliant study. AB - To investigate the prognostic value of DHCR24 for patients with bladder cancer (BC). We used public bladder cancer microarray studies to evaluate the expression of DHCR24 between normal bladder tissues and BC cells, to investigate the relationship between the expression of DHCR24 and the clinical features of BC patients. Survival analysis was performed to investigate the correlation between DHCR24 expression and the survivals of BC patients. Gene set enrichment analysis was conducted to identify relevant mechanisms. The results showed that DHCR24 was up-regulated in BC cells compared with that in normal bladder tissues (P = .0389). Results of chi-square test suggested that BC patients in DHCR24 low expression group were proved to have better clinical characteristics (including tumor grade, disease progression, T staging, and N staging) as compared with those in DHCR24 low expression group (P < .0001, P = .002, P = .005, and P = .002, respectively). BC patients in DHCR24 low expression group were associated with better cancer-specific survival and overall survival (P < .0001 and P = .0008, respectively). DHCR24 might promote the proliferation of BC cells through several oncogenesis-associated biological processes (estrogen response, heme metabolism, P53 pathway, cholesterol homeostasis, mTORC1 signaling, peroxisome, xenobiotic metabolism, glycolysis, and protein secretion). Thus, DHCR24 might be a therapeutic target for patients with BC. PMID- 30278484 TI - Understanding molecular mechanisms of Rhodiola rosea for the treatment of acute mountain sickness through computational approaches (a STROBE-compliant article). AB - Rhodiola rosea has been used in the treatment of acute mountain sickness (AMS) for a long time, but the mechanism of its action is not still completely clear. In this paper, the therapeutic mechanism of R rosea for AMS was investigated by analysis of the relationship between R rosea compositions and hypoxia-inducible factor 1 (HIF-1) degradation pathway.System biology and network biology, computational approaches were used to explore the molecular mechanisms of traditional Chinese medicine (TCM).Our results showed that chemical compositions of R rosea could inhibit the targets of HIF-1 degradation pathway in multi composition/multi-target ways.We conclude that the 18 components with more than 2 targets and 5 targets (arrest-defective-1 [ARD1], forkhead transcription factor [FOXO4], osteosarcoma-9 [OS-9], prolyl hydroxylase 2 [PHD2], human double minute 2 [Hdm2]) deserve to be noticed, and PHD2, receptor for activated C-kinase1 (RACK1) and spermidine/spermine-N1-acetyltransferase-1 (SSAT1) may be the targets of active ingredients of rhodionin, rhodiosin, and rhodiolatuntoside, respectively. PMID- 30278486 TI - Primary malignant peripheral nerve sheath tumor of prostate in a young adult: A case report. AB - RATIONALE: Prostate sarcoma has been reported to represent 0.7% of primary prostate malignancies. Leiomyosarcoma and rhabdomyosarcoma are the most common sarcomas of the prostate. Malignant peripheral nerve sheath tumor (MPNST) of the prostate is very rare. PATIENT CONCERNS: A 22-year-old man presented with gross hematuria and voiding difficulty for 2 weeks. Magnetic resonance imaging showed a 6-cm mass in the left lobe of the prostate. DIAGNOSES: Core needle biopsy results revealed high-grade sarcoma, suggestive of poorly differentiated synovial sarcoma. The final diagnosis of laparoscopic prostatectomy was MPNST, because it did not show the presence of SYT-SSX fusion transcripts on reverse transcription polymerase chain reaction analysis. INTERVENTIONS: Adjuvant radiotherapy was planned because preoperative positron emission tomography-computed tomography (CT) did not show any metastatic lesion and the resection margin was microscopically involved. However, chest CT showed multiple lung metastases a month after prostatectomy. A chemotherapeutic regimen of doxorubicin and ifosfamide was administered. OUTCOMES: The best response to chemotherapy was partial response. After several courses of chemotherapy, he died 9 months after the surgery. LESSONS: Primary prostate sarcoma and even MPNST are extremely rare. MPNST of the prostate has seldom been reported. This report may help diagnose and manage the disease. PMID- 30278483 TI - Prevalence and determinants of depression in caregivers of cancer patients: A systematic review and meta-analysis. AB - BACKGROUND: Aim of this study was to estimate the prevalence rate of depression in cancer patient caregivers and to identify factors affecting depression and quality of life of cancer caregivers. METHODS: Relevant research articles were retrieved after literature search in several electronic databases. Random effects meta-analyses were performed to obtain pooled estimates of the prevalence rates of depression and anxiety; their respective scores, and quality of life scores. Significant relationships between depression and factors related to depression and quality of life reported in individual studies were identified. RESULTS: Thirty studies were included. Overall, 21,149 caregivers were appraised in these studies (age 52.65 years [95% CI: 49.65, 55.65]; 31.14% [28.40, 33.89] men). The prevalence of depression and anxiety were 42.30% [33.31, 51.29] % and 46.55% [35.59, 57.52], respectively. Quality of life score, as measured with Caregiver Quality of Life-Cancer scale was 64.55 [47.44, 81.66]. Patient's condition, caregiving burden, duration of caregiving, spouse caregiver, caregiver being unemployed, caregiver with chronic disease, caregiver's sleep quality, caregiver's avoidance, financial problems, and female sex were positively associated with depression whereas overall quality of life of caregiver, pre-loss grief, caregiver's education level, caregiver's age, caregiver's sense of coherence, and caregiver's bondage with patient were negatively associated with depression in caregivers. CONCLUSION: A considerably high prevalence of depression is found in cancer patient caregivers. Several factors may affect depression and their quality of life of cancer patient caregivers. PMID- 30278485 TI - Association of CYP2E1 gene polymorphisms with bladder cancer risk: A systematic review and meta-analysis. AB - BACKGROUND: Human cytochrome P450 (CYP) is an enzyme responsible for the metabolic activation of many carcinogens, including nitrosamines. CYP2E1 represents a major CYP isoform and is expressed in the human urothelial cells. Recent studies have investigated the association of CYP2E1 gene polymorphisms with bladder cancer risk but have shown contradictory results. Hence, we performed a systematic literature review and meta-analysis to assess the association between CYP2E1 gene polymorphisms and bladder cancer. METHODS: Systematic literature searches were conducted with PubMed, Excerpt Medica Database, Science Direct/Elsevier, China National Knowledge Infrastructure, and the Cochrane Library up to January 2018 for studies that involved the association of CYP2E1 gene polymorphisms with bladder cancer risk. A meta-analysis was performed with Review Manager and Stata software. Combined odds ratios (ORs) were identified with 95% confidence intervals (CIs) in a random or fixed effects model. ETHICS: The protocol was approved by the institutional review board of each study center. Written informed consent will be obtained from all patients before registration, in accordance with the Declaration of Helsinki. RESULTS: Eight studies were identified, including 1733 cases of bladder cancer and 1814 normal controls. Our results illustrated that there are significant associations between CYP2E1 gene polymorphisms and bladder cancer in all genetic models (P < .05). The combined ORs and 95% CIs were as follows for each model: additive model [OR 0.56; 95% CI (0.38-0.82)]; dominant model [OR 0.79; 95% CI (0.67-0.93)]; recessive model [OR 0.61; 95% CI (0.41-0.89)]; codominant model [OR 0.80; 95% CI (0.67-0.96)]; allele model [OR 0.75; 95% CI (0.59-0.95)]. A subgroup study showed that there are also significant associations between CYP2E1 gene polymorphisms and bladder cancer in Asian people. However, there are no significant associations between CYP2E1 gene polymorphisms and bladder cancer in Caucasian populations. CONCLUSIONS: The present study provides evidence for an association between CYP2E1 gene polymorphisms and bladder cancer progression, and suggests that CYP2E1 gene polymorphisms might be a protective factor against bladder cancer in Asian people. However, studies with larger sample sizes are needed to confirm the correlation between CYP2E1 gene polymorphisms and bladder cancer. PMID- 30278487 TI - Impact of sarcopenia on outcomes of patients undergoing pancreatectomy: A retrospective analysis of 107 patients. AB - To evaluate the prevalence of sarcopenia in patients undergoing pancreatic surgery and to examine its impact on the surgical outcomes and survival of patients.Skeletal muscle index (SMI) was measured on preoperative CT. A patient was considered sarcopenic if SMI was <38.5 cm/m for a female or <52.4 cm/m for a male. Postoperative pancreatic fistula (POPF) and severe morbidity (Clavien>=3) were analyzed. Survival of patients with cancer was calculated using the Kaplan Meier method.In total, 107 consecutive patients were included. Among them, 50 (47%) patients were sarcopenic and 65 (60%) were undernourished. The rates of severe morbidity and mortality were comparable between sarcopenic and nonsarcopenic groups. However, all POPF grade B or C and deaths occurred in the sarcopenic or nonsarcopenic overweight group (BMI > 25) with significantly lengthened hospital stays (P = .003). After pancreatectomy for cancer, 31 (40.2%) patients showed postoperative recurrence and 23 (29.9%) died after a median follow-up of 15 +/- 13.5 months. Despite comparable histological types and stages, the median overall and disease-free survivals were lower in sarcopenic patients (16 months vs not reached, P = .02 and 11.1 months vs 22.5 months; P = .04, respectively). The multivariate analysis revealed that, sarcopenia trended to increase the risk of death (HR = 2.04, P = .07).Sarcopenia negatively impacted short- and long-term outcomes in patients undergoing pancreatectomy. PMID- 30278488 TI - Efficacy of common salvage chemotherapy regimens in patients with refractory or relapsed acute myeloid leukemia: A retrospective cohort study. AB - To assess treatment response and overall survival (OS) in refractory or relapsed acute myeloid leukemia (R/R AML) patients treated by different common salvage chemotherapy regimens.Medical records data from 142 R/R AML patients were reviewed in this retrospective study. Patients were treated with regimens based on the following drugs: cytarabine, granulocyte colony-stimulating factor (G CSF), and fludarabine (FLAG) (n = 46); cytarabine and G-CSF in addition to aclarubicin or daunorubicin (CAG/DAG) (n = 30); cytarabine, G-CSF, and cladribine (CLAG) (n = 27); cytarabine, etoposide, and mitoxantrone (MEA) (n = 17); cytarabine plus idarubicin, daunorubicin, or mitoxantrone (IA/DA/MA) (n = 12); and homoharringtonine, cytarabine, and aclarubicin or daunorubicin (HAA/HAD) (n = 10).A total of 43 (35.2%) patients achieved complete remission (CR), 60 (49.2%) patients achieved overall remission rate (ORR), and 18 (14.8%) patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT) after CR. Median OS was 8.0 (95% CI 6.6-9.4) months with a 1-year OS rate of (29.9 +/- 3.9)% and 3 year OS rate of (11.1 +/- 3.6)%. No difference of CR (P = .621), ORR (P = .385), and allo-HSCT (P = .537) achievement was observed among different chemotherapy regimens. Interestingly, we observed that the CLAG-based regimen did not affect CR (P = .165), while it achieved a numerically higher ORR (P = .093) and was an independent factor for prolonged OS (P = .016). No other regimens were determined to be correlated with CR, ORR, or OS.FLAG-, CAG/DAG-, CLAG-, MEA-, IA/DA/MA- and HAA/HAD-based regimens were found to achieve similar CR rates, while the CLAG based regimen achieved numerically higher ORR rates and significant favorable OS. Therefore, CLAG-based regimens should be a prioritized treatment option for R/R AML patients. PMID- 30278489 TI - Effects of different doses of intranasal dexmedetomidine on preoperative sedation and postoperative agitation in pediatric with total intravenous anesthesia undergoing adenoidectomy with or without tonsillectomy. AB - Dexmedetomidine is a highly selective alpha2 receptor agonist, this study aimed to investigate the effects of different doses of intranasal dexmedetomidine on the preoperative sedation and postoperative agitation in pediatric with total intravenous anesthesia (TIVA) for adenoidectomy with or without tonsillectomy.This is a double-blind placebo-controlled randomized trial. Pediatric were randomly divided into the D1, D2, and S groups, each group contained 30 patients. Twenty-five to 40 minutes before surgery, the D1 and D2 groups received intranasally dexmedetomidine 1 MUg kg or 2 MUg kg, respectively, while the S group received saline of the same volume. A unified protocol of TIVA induction and maintenance was used for the three groups. The preoperative sedation, behavior of separation from parents, postoperative agitation, and postoperative pain of the children were evaluated.The proportions of satisfactory sedation in the D1, D2, and S groups were 63.3%, 76.7%, and 0%, respectively. There was a statistically significant difference between D1 and S groups (P = .000) and D2 versus S groups (P = .000), while there was no statistically significant difference between D1 and D2 groups (P = .399). As for scale on the behavior of separation from parents, there was a statistically significant difference between D1 and S groups (P = .009) and D2 versus S groups (P = .009), whereas there was no significant difference between D1 and D2 groups (P = 1). The incidence of postoperative agitation in the D1, D2, and S groups was 43.3%, 30.0%, and 63.3%, respectively, and there was a statistical difference between D2 and S groups (P = .010). There was a significant difference in the Pediatric Anesthesia Emergence Delirium (PAED) scale between D2 and S groups (P = .029). The Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) in the D2 group was significantly lower than the S group (P = .013).The intranasal dexmedetomidine of 1 or 2 MUg kg 25 to 40 minute before induction of anesthesia both could deliver effective preoperative sedation, reducing the children's distress of separation from parents. Moreover, intranasal dexmedetomidine of 2 MUg kg could deliver more effective postoperative analgesia and reduce postoperative agitation, without prolonging postoperative recovery or causing severe adverse events. PMID- 30278490 TI - Systematic review and meta-analysis of the effect of probiotic supplementation on functional constipation in children. AB - BACKGROUND: To evaluate the effect of probiotic supplementation on functional constipation in children. METHODS: We performed electronic searches in PubMed, Embase, and Cochrane Library without language restriction to identify relevant studies from the time of inception of these databases to March 2018. The relative risk or weighted mean difference was calculated to evaluate the treatment effect of probiotics using random-effects model. RESULTS: We included 4 trials reporting data on 382 children with functional constipation. Overall, there were no significant differences in treatment success (P = .697), spontaneous bowel movements per week (P = .571), fecal soiling episodes per week (P = .642), straining at defecation (P = .408), use of lactulose (P = .238), use of laxatives (P = .190), fecal incontinence (P = .139), pain during defecation (P = .410), flatulence (P = .109), and adverse events (P = .979) between probiotics and placebo. Further, the use of probiotics was associated with lower frequency of glycerin enema use (weighted mean difference -2.40, P = .004) and abdominal pain (weighted mean difference -4.80, P < .001). CONCLUSION: The findings of this study suggested that the use of probiotics was associated with significant improvement in glycerin enema use and abdominal pain but did not affect the treatment success and other function indices. PMID- 30278491 TI - Colon cancer and IgG4-related disease with orbital inflammation and bilateral optic perineuritis: A case report. AB - RATIONALE: Immunoglobulin G4-related disease (IgG4-RD) is an inflammatory condition of unknown cause. Cancer might be related to the development of certain IgG4-RD but to date, little literature documents it. PATIENT CONCERNS: A 78-year old man presented with unilateral proptosis responsive to steroids, initially attributed to nonspecific orbital inflammation. DIAGNOSIS: Right hemicolectomy was performed because of a suspicious lesion which turned out to be tubulovillous adenoma on histological analysis. Eight months after the surgery, a mass infiltrating the mesentery was found and biopsy revealed IgG4-RD. INTERVENTIONS: Both the orbital inflammation and abdominal mass infiltrating the mesentery were responsive to steroids and rituximab administered to treat IgG4-RD. OUTCOMES: In the course of IgG4-RD, the patient developed bilateral optic perineuritis, causing bilateral visual loss. Colon cancer with synchronous multiple liver metastases was found 1 year after rituximab treatment. LESSONS: This case raises the possibility of IgG4-RD being a paraneoplastic syndrome in some patients. Cancer screening should probably be performed in some elderly patients diagnosed with IgG4-RD. PMID- 30278492 TI - ST segment elevation myocardial infarction (STEMI) patients are more likely to achieve lipid-lowering treatment goals: A retrospective analysis of patients presenting with first acute coronary syndromes. AB - Statin nonadherence or discontinuation is associated with increased cardiovascular events. Many factors related to the physicians or the patients are influential in this. We aimed to compare the compliance with statin therapy between the patients who first presented with ST-elevation myocardial infarction (STEMI), non-ST-elevation myocardial infarction (NSTEMI), and unstable angina pectoris (UA) based on the target achievement according to the current dyslipidemia guidelines.We retrospectively acquired all the information about demographic characteristics, in-hospital revascularization procedures, prescribed treatments, and index and up to 6-month follow-up laboratory results of the first acute coronary syndrome patients. Acute coronary syndrome patients were divided into 3 groups as STEMI, NSTEMI, and UA.The STEMI group consisted of 260 patients, NSTEMI group consisted of 560 patients, and UA group consisted of 206 patients. Seventy-six percent of patients underwent percutaneous coronary interventions, 18.3% were managed medically, and 5.7% were referred for coronary artery bypass grafting. There was a significant decrease in low-density lipoprotein-cholesterol (LDL-C) values with the statin treatment at the follow-up in all 3 groups (for all P < .001). In the STEMI group, the percentage of those achieving the target LDL-C level was significantly higher than those who did not achieve the target according to both The American College of Cardiology/American Heart Association (ACC/AHA) and European Society of Cardiology dyslipidemia guidelines. The LDL-C target achievement rates were also higher in the STEMI group than in the NSTEMI and UA groups.Our study concluded that statin treatment goals were more attained in STEMI patients than NSTEMI and UA. All physicians should encourage lifelong intensive statin treatment in UA and NSTEMI patients such as STEMI patients. PMID- 30278493 TI - Early postoperative outcomes of surgery for intestinal perforation in NEC based on intestinal location of disease. AB - Current surgical strategies for necrotizing enterocolitis (NEC) include primary drainage, resection with enterostomies, and primary anastomosis. There is considerable controversy regarding the preferable surgical management of NEC. We sought to investigate whether the surgical outcomes of newborns with NEC undergoing exploratory laparotomy differed according to the location of the disease site.A total of 204 patients with NEC following laparotomy between July 2007 and May 2017 were retrospectively reviewed. Clinical outcomes, including mortality, neonatal intensive care unit (NICU) length of stay and complications, were evaluated based on the type of surgical operation.Enterostomy creation or primary anastomosis was performed in 98 patients, and 106 cases underwent laparotomy and simple drainage because of panintestinal involvement with near total intestinal compromise or no perforation. The ileum was the most commonly affected location (n = 170, 83.3%). Patients who had undergone a simple drainage procedure experienced less blood loss (P = .023) and a shorter procedure time (P = .061), although no statistical significance was attained. Infants with bowel anastomosis or ostomy had significantly shorter times to beginning enteral feeds (P = .023) and times on mechanical ventilation (P = .011) compared with infants who had undergone drainage (Student's t test). The mean NICU length of stay (P = .088) was longer for the patients with drainage, although the difference did not attain significant. No difference in the overall mortality rate was detected between the 2 groups (P = .10).The postoperative outcomes in newborns undergoing laparotomy were associated with the surgical type, which was determined by disease location in the bowel. PMID- 30278494 TI - Effects of the attenuation correction and reconstruction method parameters on conventional cardiac dynamic SPECT. AB - Nuclear cardiology has not witnessed development of new tracers or hardware for many years. Hence there is a need for the development of improvised techniques. Dynamic cardiac single photon emission computed tomography (SPECT) is one such technique that has a potential to overcome the limitations of conventional myocardial SPECT including the absolute quantification of blood flow. The main goal of this study is to evaluate the effect of attenuation correction (AC) on estimation of the washout parameters extracted from dynamic SPECT using a conventional protocol. The effect of the postprocessing on quantitative evaluation of dynamic SPECT is also assessed.A physical phantom was employed to physically simulate the dynamic behavior of a heart in the thorax. Using a dual detector SPECT system, 180 degrees tomographic data in every 90 seconds were acquired. The SPECT data were reconstructed using ordered subset expectation maximization (OSEM) method while different iterations and a Butterworth filter with different cut-off frequencies were applied. Estimated washout parameter of the time activity curves (TACs) was compared with applying AC or without it.Results show that AC can improve the bias of computed washout parameter in normal regions (average bias reduction in normal ROI: 7%). Moreover, the postreconstruction filtering and reducing the number of iterations in reconstructing phase can reduce the variance of the computed washout values in normal regions (from 3.99% for cut-off frequency 0.5 cycle/cm and 32 times update in OSEM to 2.05% for cut-off frequency 0.35 cycle/cm and 16 times update in OSEM). They also reduce the actual size of the defect region (13% reduction in defect extent for above change in reconstruction parameters).According to the results, the AC and postprocessing filtration can directly affect the standard deviation of washout value acquired by cardiac dynamic SPECT. These parameters also showed a direct effect on the defect extent in final results. The study showed that the AC may partly improve the bias of calculated normal washout value. The effect of attenuation correction on the defective washout value could not be answered comprehensively in this paper. PMID- 30278496 TI - Histopathologic features of alcoholic cardiomyopathy compared with idiopathic dilated cardiomyopathy. AB - BACKGROUND: The histologic difference between alcoholic cardiomyopathy (ACM) and idiopathic dilated cardiomyopathy (IDCM) is unclear. The present study aimed to identify the quantitative pathologic features of ACM compared with IDCM. METHODS: Specimens from 6 regions (anterior left ventricle [LV], lateral LV, inferior LV, interventricular septum [IVS], anterior right ventricle [RV], and inferior RV) were sampled from each explanted heart. Specimens from 4 healthy donor hearts were obtained as normal control. Tissues were sectioned and Masson trichrome stained. Histomorphometry was performed to evaluate the amount of myocyte, fibrosis, fatty tissue, and interstitium by Image-Pro Plus 6.0 (Media Cybernetics). RESULTS: A total of 408 specimens were obtained from 34 ACMs and 34 IDCMs; 8 specimens were obtained from 4 healthy donor hearts. Compared to healthy donor hearts, we observed an increase in fibrosis which replaces myocytes in myocardium of end-stage cardiomyopathy. The overall myocyte ratio in myocardium was 69.5 +/- 8.7% in ACM vs 71.9 +/- 7.4% in IDCM (P < .05). The percentage of interstitium was 10.8 +/- 4.8% in ACM vs 9.2 +/- 6.2% in IDCM (P < .05). A significant difference of fibrosis, fatty tissue was not discovered. Moreover, the myocyte area was 65.37 +/- 11.8% in ACM LV vs 70.03 +/- 9.0% in IDCM LV (P < .001). CONCLUSION: We described histologic characteristics in ACM and IDCM. There might be a quantitative difference of myocyte, interstitium in myocardium between ACM and IDCM, especially in LV. No difference was found in the percentage of fibrosis between the 2 groups. PMID- 30278495 TI - The effect of dexmedetomidine in coracoid approach brachial plexus block under dual stimulation. AB - BACKGROUND: Coracoid approach brachial plexus block (CABPB) is safe and effective for clinical anesthesia and analgesia. Dual stimulation can enhance the block effect of CABPB when using nerve stimulator. Dexmedetomidine is a highly selective alpha-adrenoceptor agonist and it can prolong the duration of anesthesia when it is added into local anesthetics. The aim of this study was to assess the effects of dexmedetomidine on the duration of anesthesia and the effective postoperative analgesia time when it was mixed with ropivacaine for CABPB under dual stimulation. METHODS: A total of 60 patients were randomly assigned into 2 groups (groups D and C), 30 patients in each group. CABPB were guided by nerve stimulator under dual stimulation. Each patient received 40 mL of 0.375% ropivacaine (group C), or 40 mL of 0.375% ropivacaine mixed with 1 MUg/kg dexmedetomidine (group D). The duration of anesthesia, the effective postoperative analgesia time, sensory and motor block onset time, visual analog scale (VAS), and the cumulative dose of rescue tramadol were recorded. RESULTS: Twenty-eight patients in each group were analyzed. The duration of anesthesia was longer in group D as compared with group C (759 vs 634 minutes, P < .05) and the effective postoperative analgesia time was longer in group D as compared with group C (986 vs 789 minutes, P < .05) too. The onset time of sensory and motor blocks were not significantly different between the 2 groups (P > .05). The VAS was similar in the 2 groups at 6 and 12 hours after block (P > .05), but it was lower in group D at 24 hours after block as compared to group C (P < .05). The cumulative dose of rescue tramadol during the first 48 hours postoperative period was significantly lower in group D as compared to group C (P < .05). No significant changes were observed in vital signs in either group. CONCLUSION: The addition of 1 MUg/kg dexmedetomidine to ropivacaine extends the duration of anesthesia and the effective postoperative analgesia time for CABPB under dual stimulation. The VAS at 24 hours after block and the demand for rescue tramadol during the first 48 hours postoperative period are lower as well without side effects in the study group.(Registered in ClinicalTrials.gov id. NCT02961361). PMID- 30278497 TI - Laparoscopic segmental resection of the rectum for upper rectal intussusception caused by a giant rectal lipoma: A case report. AB - RATIONALE: Colonic lipomas are rare benign tumours, usually without any symptoms, and most occur in the caecum and ascending colon. We describe a patient with upper rectal intussusception caused by a giant rectal lipoma; no similar report of this type of case has been published. PATIENT CONCERNS: We report the case of a patient who suffered from repeated bloody stools. A wide pedicle polyp (size, 6.5 * 4.5 * 3.5 cm) was detected at the 15th centimetre of the anal canal via an electronic colonoscope. At the initial part of the rectum, intussusception caused by a 6.5-cm fat-density mass was observed via abdominal contrast-enhanced computed tomography. DIAGNOSIS: Upper rectal intussusception caused by a giant rectal lipoma. INTERVENTIONS: Due to the large size of the polyp, an endoscopic polypectomy could not be performed. We performed laparoscopic segmental resection of the rectum (with preservation of the left colic artery [LCA]). OUTCOMES: The patient was discharged on the 7th postoperative day without any complications, was monitored on a regular basis at our outpatient department and was free of symptoms at a 3-month follow-up visit. LESSONS: Laparoscopic segmental resection of the rectum with LCA preservation is safe and feasible for the treatment of upper rectal intussusception caused by a giant rectal lipoma. PMID- 30278498 TI - Treatment outcomes of patients with non-bacteremic pneumonia caused by extensively drug-resistant Acinetobacter calcoaceticus-Acinetobacter baumannii complex isolates: Is there any benefit of adding tigecycline to aerosolized colistimethate sodium? AB - Few therapeutic options exist for various infections caused by extensively drug resistant Acinetobacter calcoaceticus-Acinetobacter baumannii (XDR-Acb) complex isolates, including pneumonia. This study investigated the clinical efficacy between aerosolized colistimethate sodium (AS-CMS, 2 million units thrice a day) treatment alone or in combination with standard-dose tigecycline (TGC) in patients with non-bacteremic pneumonia due to XDR-Acb, and explored the factors influencing patients' 30-day mortality.A 1:1 case (n = 106; receiving TGC plus AS CMS) control (receiving AS-CMS alone with matching scores) observational study was conducted among adult patients with non-bacteremic XDR-Acb complex pneumonia in a Taiwanese medical center from January 2014 through December 2016. The clinically relevant data were retrospectively recorded. The primary endpoint was 30-day case fatality. Secondary endpoints investigated that if the co morbidities, XDR-A. baumannii as a pneumonic pathogen, therapy-related factors, or airway colonization with colistin-resistant Acb negatively influenced the 14 day clinical condition of enrolled patients.A higher 30-day mortality rate was noted among the group receiving combination therapy (34.0% vs 22.6%; P = .17). The >=7-day AS-CMS therapy successfully eradicated > 90% of airway XDR-Acb isolates. Nevertheless, follow-up sputum specimens from 10 (6.4% [10/156]) patients were colonized with colistin-resistant Acb isolates. After the conditional factors were adjusted by multivariate logistic analysis, the only factor independently predicting the 30-day case-fatality was the failure of treating XDR-Acb pneumonia at 14 days (adjusted odds ratio [aOR] = 38.2; 95% confidence interval [CI] = 9.96-142.29; P < .001). Cox proportional regression analysis found that chronic obstructive pulmonary disease (COPD) (adjusted hazard ratio [aHR] = 2.08; 95% CI = 1.05-4.10; P = .035), chronic renal failure (aHR = 3.00; 95% CI = 1.52-5.90; P = .002), non-invasive ventilation use (aHR = 2.68; 95% CI = 1.37-5.25; P = .004), and lack of TGC therapy (aHR = 0.52; 95% CI = 0.27 1.00; P = .049) adversely influenced the 14-day clinical outcomes. Conversely, the emergence of colistin-resistant Acb isolates in the follow-up sputum samples was not statistically significantly associated with curing or improving XDR-Acb pneumonia.In conclusion, aggressive pulmonary hygiene care, the addition of TGC, and corticosteroid dose tapering were beneficial in improving the 14-day patients' outcomes. PMID- 30278499 TI - Epidemiological trends of fatal pediatric trauma: A single-center study. AB - To evaluate the potential risk factors which increase the incidence of post trauma complications and mortality in pediatric population.A retrospective cohort study was conducted on patients below 18 years of age with a fatal outcome who were admitted to an Indian level-1 trauma center between January 2013 and December 2015. This cohort was analyzed to determine the demographics, injury mechanism, injury severity, microbiological profile, and cause of death.In total, 320 pediatric patients with a fatal outcome were studied which showed male preponderance (71.56%). The median age of the patients was 11 years (range, 0.14 18 years). Median duration of stay was 1 day (range, 0-183 days). Fall and road traffic accidents were the common mechanisms of trauma while the main injury was head injury. In total, 857 clinical samples were received from 56 patients. The clinical samples from 35 (10.94%) patients were culture positive. Culture-proven infections were significantly correlated with the length of hospital stay (P = .001). In total, 212 organisms were isolated from 193 positive samples of which gram-negative bacteria were predominant (89.15%). The most common gram-positive bacterial isolate was Staphylococcus aureus (12, 52.17%), while Acinetobacter baumannii (66, 34.92%) was the most prevalent gram-negative bacterial isolate followed by Pseudomonas spp. (36, 19.05%), Klebsiella pneumoniae (35, 18.52%), and Escherichia coli (16, 8.47%). Up to 100% multidrug resistance was seen in both gram-positive and gram-negative bacterial isolates. The first 24 hours after trauma were the deadliest for our patients. Head/central nervous system injury was the primary cause of disabilities and early death whereas infection attributed to prolonged hospital stay.From these observations we concluded that management of pediatric trauma requires expert, multidisciplinary, and timely interventions. Moreover, nosocomial infections with multidrug resistant gram negative bacteria challenges the accepted tenets of trauma care affecting the outcome of the pediatric population. Early identification of such high-risk patients' infection may facilitate early intervention. Thus, many deaths in pediatric group are preventable. PMID- 30278500 TI - Identification of volume parameters monitored with a noninvasive ultrasonic cardiac output monitor for predicting fluid responsiveness in children after congenital heart disease surgery. AB - No previous study has used an ultrasonic cardiac output monitor (USCOM) to assess volume parameters, such as stroke volume variation (SVV), in order to predict the volume status and fluid responsivenes in children after congenital heart disease (CHD) surgery. The present prospective trial aimed to investigate the ability of SVV and corrected flow time (FTc), which were assessed with a USCOM, for predicting fluid responsiveness in children after CHD surgery.The study included 60 children who underwent elective CHD surgery. Data were collected after elective CHD surgery. After arrival at PICU, the continuous invasive blood pressure was monitored. Once the blood pressure (BP) decreased to the minimum value, 6% hydroxyethyl starch (130/0.4) was administered (10 mL/kg) over 30 minutes for volume expansion (VE). The USCOM was used to monitor the heart rate, central venous pressure, stroke volume index (SVI), cardiac index, SVV, FTc of the children before and after VE. Additionally, the SVI change (DeltaSVI) was calculated, and the inotropic score (IS) was determined. Children with a DeltaSVI >=15% were considered responders, while the others were considered nonresponders. The children were also divided into IS <=10 and IS >10 groups.Of the 60 children, 32 were responders and 28 were nonresponders. We found that only SVV was significantly correlated with DeltaSVI (r = 0.42, P < .01). SVV could predict fluid responsiveness after surgery (area under the curve [AUC]: 0.776, P < .01), and the optimal threshold was 17.04% (sensitivity, 84.4%; specificity, 60.7%). Additionally, the SVV AUC was higher in the IS >10 group than in the IS <=10 group (0.81 vs 0.73).SVV measured with a USCOM can be used to predict fluid responsiveness after CHD surgery in children. Additionally, the accuracy of SVV for predicting fluid responsiveness might be higher among patients with an IS >10 than among those with an IS <=10. PMID- 30278501 TI - The impact of previous abdominal surgery on clinical characteristics and prognosis of pyogenic liver abscess: A 10-year retrospective study of 392 patients. AB - Many pyogenic liver abscess (PLA) patients underwent abdominal surgery before. However, little is known about the impact of previous abdominal surgery on the clinical characteristics and prognosis of PLA.The clinical data of 392 adult PLA patients who received treatment at our hospital from January 1, 2007 to December 31, 2016 were collected. The demographic data, cause, comorbidities, surgery history, clinical features, laboratory results, imaging findings, microbiological characteristics, choices of treatment, and clinical outcomes were analyzed.In all, 177 PLA patients (45.2%) underwent abdominal surgery before. The median time for the occurrence of PLA after the most recent abdominal surgery was 2.0 (interquartile range 0.25, 6.0) years. PLA patients with a previous abdominal surgery history were more likely to have underlying diseases and presented with more abnormal laboratory values. Klebsiella pneumonia and Escherichia coli were the most common pathogens. Previous abdominal surgery appeared to increase the incidence of E coli. More PLA patients without a previous abdominal surgery history required surgical drainage. However, there were no differences in PLA related complications, days required for temperature normalization, and length of hospital stay between the 2 groups.Because a large number of PLA patients had a history of abdominal surgery, and proper screening should be performed for patients with any suspicion of a liver abscess after abdominal surgery. Despite the differences in the coexisting conditions, clinical and microbiological characteristics between PLA patients with and without a previous abdominal surgery history, the overall short-term outcomes were comparable. PMID- 30278502 TI - Association of miRNA-146a rs2910164 and miRNA-196 rs11614913 polymorphisms in patients with ulcerative colitis: A meta-analysis and review. AB - BACKGROUND: It has been reported that the single nucleotide polymorphisms (SNPs) miRNA-196 (miR-196) rs11614913 and miRNA-146a (miR-146a) rs2910164 are related to susceptibility to ulcerative colitis (UC). Because the previously reported results have been mixed and uncertain, the aim of this study was to perform a meta-analysis and review to assess the relationship between these 2 SNPs and UC risk. METHODS: In this analysis, 5 studies involving 1023 cases and 1769 controls for miR-196 rs11614913 and 4 studies involving 827 cases and 1451 controls for miR-146 rs2910164 were included. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were used to pool the effect size. RESULTS: A decreased risk of UC was identified in homozygote comparison (GG vs CC: OR = 0.69, 95% CI: 0.52-0.93, P = .02), recessive comparison (GG vs CG + CC: OR = 0.74, 95% CI: 0.59-0.92, P = .007), and dominant comparison (GG + CG vs CC: OR = 0.79, 95% CI: 0.65-0.97, P = .02) of miR-146 rs2910164 in Asian but not Caucasian population. No evidence of an association was shown between the rs11614913 polymorphism and UC risk in allelic, heterozygote, homozygote, recessive, and dominant models in both Caucasian and Asian populations (P > .05). CONCLUSIONS: MiR-146 rs2910164, but not miR-196 rs11614913, was associated with a decreased risk of UC in Asian population. However, the results should be treated with caution because of the limited sample size and heterogeneity. Well-designed studies with large sample sizes and more ethnic groups are needed to validate the risks identified in the current meta-analysis and review. PMID- 30278503 TI - Prosthesis satisfaction in lower limb amputees: A systematic review of associated factors and questionnaires. AB - BACKGROUND: Factors influencing patient satisfaction with a transtibial prosthesis have been studied fragmentarily. The aims of this systematic review were to review the literature regarding factors of influence on patient satisfaction with a transtibial prosthesis, to report satisfaction scores, to present an overview of questionnaires used to assess satisfaction and examine how these questionnaires operationalize satisfaction. METHODS: A literature search was performed in PubMed, Embase, PsycInfo, CINAHL, Cochrane, and Web of Knowledge databases up to February 2018 to identify relevant studies. RESULTS: Twelve of 1832 studies met the inclusion criteria. Sample sizes ranged from 14 to 581 participants, mean age ranged from 18 to 70 years, and time since amputation ranged from 3 to 39 years. Seven questionnaires assessed different aspects of satisfaction. Patient satisfaction was influenced by appearance, properties, fit, and use of the prosthesis, as well as aspects of the residual limb. These influencing factors were not relevant for all amputee patients and were related to gender, etiology, liner use, and level of amputation. No single factor was found to significantly influence satisfaction or dissatisfaction. Significant associations were found between satisfaction and gender, etiology, liner use, and level of amputation. CONCLUSION: Relevance of certain factors for satisfaction was related to specific amputee patient groups. Questionnaires assessing satisfaction use different operationalizations, making comparisons between studies difficult. PMID- 30278504 TI - Can Vulnerable Elders Survey-13 predict the impact of frailty on chemotherapy in elderly patients with gynaecological malignancies? AB - The management of gynaecological cancers in elderly women and high-risk patients is an even more relevant issue, because the increase in longevity and comorbidities. The assumption of frailty based on age alone may lead to inadequate and inappropriate treatment and frailty assessment is recommended. The aim of this study was to assess if Vulnerable Elders Survey-13 (VES-13), as indicator of frailty, can predict the toxicity of chemotherapy in gynaecological cancers.VES-13 was administered to patients aged >= 70 years with ovarian, endometrial and cervical cancers who underwent chemotherapy from 2010 to 2016.Eighty-four patients aged >= 70 years (mean age 74.6) were included, 36 patients (42.9%) resulted vulnerable (score >= 3). Thrombocytopenia and anaemia were more prevalent in the vulnerable subjects (81.3% versus 18.7%, P = .0005, and 81.8% versus 18.2%, P = .005, respectively), while neutropenia was similar between the 2 groups. Vulnerable women had higher risk of non-haematological toxicities. Most of the patients (77.4%) completed chemotherapy, but dose reductions and discontinuations were more common in the vulnerable group (66.7% versus 33.3%, P = .07 and 68.4% versus 31.6%, P = .01, respectively).To our knowledge, this is the first study to evaluate VES-13 exclusively in elderly women with gynaecological cancers. VES-13 may be useful to stratify this category of patients according to vulnerability in order to identify women at risk of toxicity and to prevent complications induced by chemotherapy. PMID- 30278506 TI - Trisomy 22 with long spina bifida occulta: A case report. AB - INTRODUCTION: Complete non-mosaic trisomy 22 is a fatal chromosomal disorder that only few fetuses can survive over 12 weeks as reported. Prenatal sonographic findings combined with postnatal or postmortem discoveries showed characteristic multi-systematic anomalies. PATIENT CONCERNS: The unborn baby of a 35-year-old pregnant woman was found to have several anomalies during a prenatal sonographic scan, including intrauterine growth retardation, ventricular septal defect, flat facial profile, and unclear bilateral kidney structures. DIAGNOSES: The fetus was diagnosed as having complete non-mosaic trisomy 22 by chromosomal analysis. INTERVENTIONS: The pregnancy was terminated at 24 weeks, and autopsy was permitted. OUTCOMES: Postmortem examinations revealed additional long-sectional spina bifida occulta and imperforate anus. CONCLUSIONS: This was the first time a case of spinal cord defect was reported in trisomy 22 fetuses. More attention should be paid to the spinal cord during sonographic examinations in trisomy 22 fetuses. PMID- 30278505 TI - Matrix metalloproteinase-2 gene polymorphisms are associated with ischemic stroke in a Hainan population. AB - Ischemic stroke is a complex vascular disease, which has become 1 of the major causes of morbidity and mortality worldwide. More and more data showed that matrix metalloproteinases (MMPs), in particular, MMP-2 are deleterious after ischaemic stroke. This study investigated the relationship between MMP-2 and stroke risk in the Southern Chinese population.We evaluated single nucleotide polymorphisms (SNP) of MMP-2 in stroke patients in an association study using a case-control design. Six SNPs of MMP2 were selected and genotyped by Agena MassARRAY. SNPStats, Haploview was used to analyze genetic data.Two SNPs in the MMP-2 gene were significantly associated with stroke risk.For rs1132896 (C versus G allele), the C allele was significantly reduced stroke risk (OR = 0.56, 95% confidence intervals [95% CI] = 0.39-0.81, P = .002). The effect of the T allele of rs243849 was IS risk according to an additive genetic model (OR = 0.67, 95% CI = 0.47-0.96, P = .028). We did not found any strong linkage between the six SNPs (rs1132896, rs1053605, rs243849, rs243847, rs243832, rs7201)The results presented strongly indicate that MMP-2 genetic variants are an important mediator of stroke risk. PMID- 30278507 TI - Positron emission tomography/computed tomography manifestations of primary hepatic myxoid liposarcoma: A case report. AB - RATIONALE: Computed tomography (CT) and magnetic resonance imaging (MRI) are conventional used to evaluate liver tumors. Detection of fat component is considered an important clue to the imaging diagnosis of hepatic myxoid liposarcoma. However, the positron emission tomography (PET)/CT report of hepatic myxoid liposarcoma is scarce, and the metabolic characteristics of primary hepatic myxoid liposarcoma are still unknown. PATIENT CONCERNS: In this report, we report the PET/CT manifestations of a rare case of primary hepatic myxoid liposarcoma that was confirmed by pathologic examination. A 29-year-old male patient presented with a nodule adjacent to the umbilicus that had been present for 2 weeks. PET/CT showed a hypoattenuating mass with moderate uptake (maximum standardized uptake value [SUVmax] 1.9), except for a slightly hyperattenuating focal area with intense uptake (SUVmax 3.1). DIAGNOSES: The final pathologic diagnosis was confirmed, by means of laparotomy, to be a primary hepatic myxoid liposarcoma with multiple extrahepatic metastases. INTERVENTIONS: The lesions in the left liver and periumbilical abdominal wall were punctured. During the laparotomy, hepatic malignant tumors were confirmed and metastasized widely in the abdominal cavity. OUTCOMES: An abdominal CT performed 4 months after initial presentation showed extensive metastasis. LESSONS: Primary hepatic myxoid liposarcoma may manifest as moderate metabolism with less fat on PET/CT. PET/CT is not only valuable in reflecting the round cell component of hepatic myxoid liposarcoma, but also in estimating its origin. PMID- 30278508 TI - Multiple myeloma with pathologically proven skull plasmacytoma after a mild head injury: Case report. AB - RATIONALE: MM is a malignant tumor originating from the plasma cells of the bone marrow. Central nervous system myelomatosis is very rare and may be a complication of MM. PATIENT CONCERNS: A 60-year-old man presented with a slowly growing soft mass at his right frontal scalp after a mild head injury 6 months ago. DIAGNOSES: Neuroradiological examinations revealed a solid intracranial extracranial mass with an osteolytic lesion in the skull. Histopathological examination showed skull plasmacytoma, and postoperative examinations revealed multiple myeloma. INTERVENTIONS: The tumor was completely removed and the skull defect repaired with the titanium mesh. Then, chemotherapy was initiated after surgery with bortezomib and dexamethasone. OUTCOMES: The patient received eight chemotherapies within one year after surgery. LESSONS: Despite a history of head injury, a differential diagnosis should be kept in mind during the diagnosis of solid intracranial-extracranial masses, especially in the presence of osteolytic skull at the lesioned site. PMID- 30278509 TI - Face-neck lifting and ancillary procedures: A series of 203 cases. AB - Various methods and ancillary procedures have been defined in the era of face lifting surgery.The purpose of this study was to evaluate the esthetic outcomes of our face-neck cases and the importance of adding ancillary procedures based on individual assessment.We conducted a retrospective review of 203 face-neck cases, basically following the endoscopic and open principles of Vasconez. The ancillary procedures added in selected cases included genioplasty, augmentation with autologous facial superficial fascial tissue or fat injections, upper lip shortening, perioral dermabrasion, ear lobe reduction, buccal fat reduction, mentum lifting, and upper orbital rim shaving. Complications, postoperative follow-up, esthetic outcomes, and contribution of the ancillary procedures were recorded.Our esthetic face complication rates were comparable to those of previous studies and included chemosis, hematoma, cyst on the eyelid suture line, skin sloughing, scar abnormalities (hypertrophic scar and widespread scar), pseudoparalysis of the marginal mandibular branch, temporary hypoesthesia of the forehead, irregularity of the glabella after endoscopy, and asymmetry. We did not observe any comorbidity owing to genioplasty and augmentation with autologous tissue except for a case with infection after fat injection.More improvement can be obtained with careful planning of ancillary procedures in face-neck lifting surgery. PMID- 30278510 TI - Non-alpha-fetoprotein-producing adrenal hepatoid adenocarcinoma: A case report and literature review. AB - RATIONALE: Adrenal hepatoid adenocarcinoma typically secretes alpha-fetoprotein (AFP). Here, we report a case of non-AFP-producing adrenal hepatoid adenocarcinoma. Next-generation sequencing (NGS) was conducted to identify gene mutations. PATIENT CONCERNS: A 64-year-old man presented with mild back pain and unexplained weight loss for 3 months. DIAGNOSES: Contrast-enhanced magnetic resonance imaging (MRI) showed a mass (9.9 * 9.7 * 9.1 mm) above the upper pole of the left kidney. The left renal artery and vein were compressed. The tumor was positive for CK8/18, CK19, CK7, hepatocyte marker (Hepatocyte), and Hep Par 1, but negative for AFP. Plasma AFP was 2.75 ng/mL (normal range: 0-7 ng/mL). NGS revealed mutations of the following genes: ATM, CDKN2A, EGFR, STK11, TP53, BIM, and MLH1. A diagnosis of adrenal hepatoid adenocarcinoma was established. INTERVENTIONS: The treatment included 4 cycles of the mFOLFOX6 regimen (oxaliplatin, leucovorin, and fluorouracil), transcatheter arterial chemoembolization, and apatinib. OUTCOMES: The patient died 9 months after the diagnosis. LESSONS: This case highlights the importance of thorough clinical, radiological, and immunohistochemical investigation for suspected adrenal hepatoid adenocarcinoma. Metastasis from other primary tumors should be ruled out. Furthermore, AFP is not necessarily elevated in adrenal hepatoid adenocarcinoma. NGS could be helpful in establishing the diagnosis and selecting treatments. PMID- 30278511 TI - Red blood cell distribution width-to-platelet ratio as a disease activity associated factor in systemic lupus erythematosus. AB - BACKGROUND: Although different clinical and experimental parameters have been used to estimate disease activity in systemic lupus erythematosus (SLE) patients, the relationship between red blood cell distribution width-to-platelet ratio (RPR) and disease activity in SLE has not been previously illuminated. Therefore, the aim of this study was to investigate the association between RPR levels and disease activity in SLE. METHODS: This study enrolled 105 SLE patients and 105 healthy subjects. We divided the patients into 2 groups using the SLE Disease Activity Index (SLEDAI) 2000. Group 1 included patients with SLEDAI score <=9 (mild disease activity group) and group 2 with SLEDAI >9 (severe disease activity group). Correlations between RPR and disease activity were then analyzed. A subgroup follow-up analysis of 93 patients was conducted to explore the effect of SLE-related glucocorticoid therapy. RESULTS: The PLR and RPR values of SLE patients were significantly higher compared with the controls (both P < .001), whereas mean platelet volume was decreased (P < .05). The RPR level was found to be positively correlated with SLEDAI (r = 0.368, P < .001) and erythrocyte sedimentation rate (r = 0.313, P = .027). According to the receiver-operating characteristic (ROC) curve, the optimal cut-off value for predicting SLE using RPR was 0.073, and the area under ROC curve was 0.817. RPR level was correlated with clinical disease activity in SLE, and its value was normalized after treatment. CONCLUSION: RPR may be a useful measurement for the assessment of disease activity in SLE patients. PMID- 30278512 TI - Modified enhanced recovery after surgery protocols are beneficial for postoperative recovery for patients undergoing emergency surgery for obstructive colorectal cancer: A propensity score matching analysis. AB - Enhanced recovery after surgery (ERAS) is acknowledged to reduce perioperative stress in several surgical diseases. Here, we investigated whether modified ERAS is associated with beneficial effects in the setting of emergency colorectal surgery.We retrospectively evaluated the medical records of 839 consecutive patients with obstructive colorectal cancer undergoing surgical intervention at 4 institutes. Among them, 356 cases were managed with a multidisciplinary team approach to care (modified ERAS protocols), and the remaining 483 cases were treated based on traditional protocols. According to modified ERAS or traditional care, propensity score (PS) matching was performed to adjust biases in patient selection. The primary outcome was gastrointestinal function recovery. Secondary outcomes included postoperative complications and length of hospital stay.Modified ERAS was associated with postoperative gastrointestinal function recovery, including time to first flatus (P = .002), first defecation (P = .008), and prolonged ileus (P = .016). According to the Clavien-Dindo classification, fewer total episodes of grade II or higher postoperative complications were observed in patients cared for with modified ERAS than in patients with traditional care (P = .002). Median (interquartile range) postoperative hospital stay in the modified ERAS group was 6 (3-22) days versus 9 (7-27) days in the traditional care group (P < .001). Furthermore, the interval from operation to postoperative chemotherapy (d) was significantly shorter in the modified ERAS group (35.6 +/- 11.5 vs 47.6 +/- 23.8, P < .001).The modified ERAS was safe and associated with clinical benefits, including fast recovery of bowel function, reduced postoperative complications, and shorter hospital stay for patients with obstructive colorectal cancer. PMID- 30278513 TI - A multiple myeloma that progressed as type I cryoglobulinemia with skin ulcers and foot necrosis: A case report. AB - RATIONALE: Type I cryoglobulinemia is a rare and life-threatening condition. It occurs mainly in B-cell lymphoproliferative disorder. In almost half of the patients, type I cryoglobulinemia is characterized by severe cutaneous involvement. PATIENT CONCERNS: A 71-year-old man comes to our observation because of the onset of persistence of paresthesia and painful acrocyanosis in the fingers and toes. IgG-k multiple myeloma treated with chemotherapy and radiation therapy on the left iliac wing characterized his clinical history. At the evaluation of response after the first-line therapy, the patient achieved a very good partial response. At the time of progression, the same myelomatous disease has taken a typical behavior of cryoglobulinemia. DIAGNOSES: Type I multiple myeloma-associated cryoglobulinemia was diagnosed. INTERVENTIONS: The patient underwent to an immediate composite therapeutic approach based on prostanoid infusion, plasmapheresis along with second-line chemotherapy. OUTCOMES: Despite the rapid biochemical response, the ischemia of the feet worsened. Moreover, a bacterial infection overlapped. The surgical amputation of both feet was necessary. Allowing MM cytoreduction continuation the patient's clinical condition became stabilized. LESSONS: Though rare, type I cryoglobulinemia can be associated with plasma cell dyscrasias. Any delay in diagnosis and the start of therapy can cause worsening of organ damage and endanger the patient's life. Therapeutic strategies in these cases should be directed to the underlying diseases. PMID- 30278514 TI - The effective clinical outcomes of the Gufoni maneuver used to treat 91 vertigo patients with apogeotropic direction-changing positional nystagmus (apo-DCPN). AB - This study aimed to observe and analyze the effects and outcomes of patients with apogeotropic direction-changing positional nystagmus (apo-DCPN) who received Gufoni maneuver.A total of 91 patients with positional vertigo admitted to the specialized dizziness clinic in Zhejiang Provincial People's Hospital from February 2014 to August 2017 were included. The immediate treatment responses to the Gufoni maneuver were observed and recorded. The patients in whom the treatment was ineffective were followed up for 4 weeks to observe the outcome of apo-DCPN.In 21 patients, the apo-DCPN was transformed after Gufoni maneuver, and 7 patients developed transformation within 4 weeks of follow-up. Spontaneous remission of apo-DCPN within the follow-up period was observed in 55 patients who were unresponsive to the Gufoni maneuver. The prevalence of migraine was significantly higher in the early remission group (P < .05) and the period between the initial visit and nystagmus remission was significantly shorter in the group of patients with migraine history (P < .05).This study demonstrates that the immediate treatment efficacy of the Gufoni maneuver is poor in positional vertigo patients with apo-DCPN. We believe that the reason for the low efficacy is that the Gufoni maneuver is only effective for some patients with apo DCPN type HSC-BPPV. In patients with early spontaneous remission and a history of migraine, central positional nystagmus of probable vestibular migraine (VM) or benign recurrent vertigo should be considered for the mechanisms of apo-DCPN generation.

AB - Imaging of placental tissues is a difficult task, because of specific for this organ complex multicellular and 3D tissue structure. The tissue clearing systems (X-CLARITY) system is a valuable tool for the examining the expression of molecular pathways in whole tissues and organs, originally developed for brain imaging.In the present report, we utilized this technology for the examination of placental vasculature and protein expression in perfused human placental tissue.The placental tissue was sufficiently cleared with preservation of endothelial staining and fluorescent markers, allowing visualization using confocal microscopy. The CLARITY method and X-CLARITY system is a valuable tool in placental imaging. PMID- 30278516 TI - A case report of intrahepatic bile duct confluence anomalies in VACTERL syndrome. AB - RATIONALE: The clinical manifestations of VACTERL association include vertebral anomalies, anal atresia, congenital heart diseases, tracheoesophageal fistula, renal dysplasia, and limb abnormalities. The association of intrahepatic anomalies and VACTERL syndrome is a rare coincidence. VACTER syndrome and intrahepatic bile drainage anomalies might be genetically related. PATIENT CONCERNS: A 12-year-old girl presented with episodic colicky abdominal pain, nausea, and vomiting for several years. The individual episodes resolved spontaneously within a few days. She had a history of VACTERL syndrome, including a butterfly shape of the L3 vertebra, anal atresia, and an atrial septal defect. DIAGNOSES: On laboratory findings, abnormal liver function tests included elevated total bilirubin, alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyltransferase. There was no significant abnormal finding in hepatobiliary system sonography except mild gallbladder wall thickening. We performed magnetic resonance cholangiopancreatography and demonstrated an abnormal intrahepatic bile duct confluence, which showed 3 bile ducts draining directly into the neck of the gallbladder. INTERVENTION: Her symptoms related to bile reflux during gallbladder contraction. Cholecystectomy with choledochojejunostomy was undertaken because segments of the bile drainage were intertwined. OUTCOMES: After surgery, her symptoms decreased, but abdominal discomfort remained due to uncorrected left intrahepatic anomalies. LESSONS: Although hepatobiliary anomalies are not included in VACTERL association diagnostic criteria, detailed hepatobiliary work up is needed when gastrointestinal symptoms are present in VACTERL association patients. PMID- 30278517 TI - The effect of nicotine patches on craving in the brain: A functional MRI study on heavy smokers. AB - BACKGROUND: Smoking is a common phenomenon and kills over 6 million people every year. Many smokers try to quit smoking by using nicotine replacement therapy (NRT). Most of the time, relapse occurs in less than six months after finishing the program of NRT. We performed a single blinded study in which our aim was to figure out what the effect of the nicotine patch is on craving in the brain of smokers deprived from smoking. METHODS: Five heavy smokers (Fagerstrom Test for Nicotine Dependence >=4) underwent a functional magnetic resonance imaging (fMRI) in 4 random conditions: smoking (S); smoking deprivation (SD); SD combined with a NP (SD + NP); SD combined with a placebo patch (SD + PP). Visual stimulation provoked craving in block design by randomly displaying images of smoking related scenes. After image preprocessing, a fixed-effect analysis was performed to compare average group activations. The Questionnaire for Smoking Urges (QSU) was obtained before and after each scan. RESULTS: The fMRI results showed higher activation in areas involved in craving in S compared with SD + NP, SD + PP, and SD. In the SD + NP, limbic circuit and attention area were higher activated compared with SD and SD + PP. The SD + PP and SD showed higher activation in the frontal cortex and limbic system compared with S and SD + NP. Nonsmokers showed higher limbic activation compared with SD.The QSU increased significantly after the fMRI experiment in S (P = .036).The SD had higher QSU scores compared with the S before (P = .002), and also after (P = .022) the fMRI experiment. The NP showed lower scores than the SD before the experiment (P = .046). CONCLUSION: The fMRI experiment revealed lower activity in areas associated with attention when subjects were nicotine deprived (SD + PP and SD). Areas involved with craving showed less activity when nicotine is present (S and SD + NP). The QSU showed a significant difference between SD and when nicotine is present (S and SD + NP). PMID- 30278518 TI - Applying Gini coefficient to evaluate the author research domains associated with the ordering of author names: A bibliometric study. AB - BACKGROUND: Team science research includes the number of coauthors in publications. Many papers have discussed the ordering of author names and the contributions of authors to a paper. However, no paper addresses the relation between authors' research domains and personal impact factors (PIF) with the ordering of author names. We aimed to apply Gini coefficient (GC) to evaluate the author research domains associated with the PIF and the ordering of author names on academic papers. METHODS: By searching the PubMed database (Pubmed.com), we used the keyword "medicine" [journal] and downloaded 10,854 articles published from 1969 to 2018. A total number of 7502 articles labeled with complete author's countries/areas were included in data analysis. We also proposed a PIF index and jointly applied social network analysis (SNA), the GC, and Google Maps to report the following data with visual representations: the trend of author collaboration in Medicine; the dominant nations and keywords in Medicine; and the author research domains in Medicine associated with the PIF and the ordering of author names on academic papers. RESULTS: The trend of author collaboration in Medicine is slightly declining (= -0.06) based on the number of authors per article. The mean number of individuals listed as authors in articles is 7.5. Most first authors are from China (3649, 48.64%) and Taiwan (847, 11.29%). The median of GC (0.32) and PIF (0.74) for the middle authors are obviously less than those for the first (0.53, 2.19) and the last authors (0.42, 2.61). A perfect positive linear relation with a large effect exists between GC and PIF because the correlation coefficient is 0.68 (>0.50, t = 2.48, n = 9). CONCLUSION: Results suggest that the corresponding author is submitting the manuscript to the target journal with a core author's academic background and the personal impact factor related to the research domain and the journal scope in the future. As such, peer reviewers can quickly determine whether the manuscript is a potentially citable research paper. PMID- 30278519 TI - Predictive values of CSS and NIHSS in the prognosis of patients with acute cerebral infarction: A comparative analysis. AB - This study aims to investigate the predictive values of the Chinese Stroke Scale (CSS) and National Institutes of Health Stroke Scale (NIHSS) in the prognosis of patients with acute cerebral infarction.A total of 399 patients with acute cerebral infarction were assessed using CSS and NIHSS within 1 day after admission. Then, the receiver operating characteristic (ROC) curves were established, and the area under the curves of these 2 scoring systems was compared.The area under the curve of CSS and NIHSS was 0.796 and 0.794, respectively.CSS and NIHSS have good predictive values for the prognosis of patients with acute cerebral infarction. PMID- 30278521 TI - Association between blood neutrophil-to-lymphocyte ratio and severity of coronary artery disease: Evidence from 17 observational studies involving 7017 cases. AB - This study aimed to evaluate the association between blood neutrophil-to lymphocyte ratio (NLR) and severity of coronary artery disease (CAD), and investigate the diagnostic ability and optimal cut-off value of NLR in predicting severe stenosis in CAD.A systematic search was conducted in public databases to identify all relevant studies. Weighted mean difference (MD) and 95% confidence interval (CI) were pooled for continuous univariate data, and odds ratios (OR) and 95% CI were calculated for dichotomous multivariate data.Seventeen studies were included in this meta-analysis with a total of 7017 CAD cases. For continuous univariate data, the cases with the highest stenosis category had a significantly higher NLR level than those with lowest stenosis category (MD: 1.57, 95% CI: 1.06-2.09; n = 17). After further classification according to the Gensini or SYNTAX score, the cases with severe stenosis demonstrated a higher NLR than those with mild stenosis (MD: 2.33, 95% CI: 1.22-3.43; n = 6) and moderate stenosis (MD: 1.92, 95% CI: 0.80-3.04; n = 6). Compared with mild stenosis, NLR was also higher in those with moderate-to-severe stenosis (MD: 1.34, 95% CI: 0.77 1.92; n = 6) and moderate stenosis (MD: 0.52, 95% CI: 0.36-0.68; n = 6). For dichotomous multivariate data, high NLR levels were recognized as an independent predictor for severe stenosis in CAD (OR: 1.50, 95% CI: 1.32-1.72; n = 11). NLR showed a diagnostic ability in predicting severe stenosis in CAD (area under receiver operating characteristics [ROC] curve [AUC]: 0.66, 95% CI: 0.64-0.68; n = 8), with the cut-off ranging from 1.95 to 3.97. Subgroup analysis and sensitivity analysis showed the results were robust. Begg's test detected no significant publication biases.This study suggested that high blood NLR was associated with the severity of CAD, and it might be useful for predicting severe stenosis in CAD. PMID- 30278520 TI - Role of Ginkgo biloba extract as an adjunctive treatment of elderly patients with depression and on the expression of serum S100B. AB - OBJECTIVE: To explore the effect of ginkgo biloba extract (EGb) as an adjunctive treatment of elderly patients with depression and the effect on the expression of serum S100B. METHODS: 136 elderly patients with depression were divided into EGb + citalopram (Cit) group and Cit group equally. Efficacy was evaluated by Hamilton Depression Rating Scale (HAMD). Wisconsin Card Classification Test (WCST) was used to evaluate cognitive function. Serum S100B expression was measured with ELISA. The relationship of S100B with HAMD, Hamilton Anxiety Scale (HAMA) score, and WCST results was evaluated subsequently. RESULTS: The time of onset of efficacy was significantly shorter in EGb + Cit group. There were significant differences in HAMD and HAMA scores after treatment than before treatment between groups (all P < .05). After treatment, total number of WCST test, the number of continuous errors and non-persistent errors in both groups were less than those before treatment. The correct number and classifications number were increased than before treatment. In EGb + Cit group, correct numbers and classifications were increased, and the number of persistent errors was decreased. After treatment, S100B level was decreased, and S100B levels change in EGb + Cit group was greater than in Cit group. Serum S100B level was positively correlated with HAMD and HAMA scores before treatment and positively correlated with persistent errors number in WCST. CONCLUSION: EGb, as an adjunctive treatment, can effectively improve depressive symptoms and reduce expression of serum S100B, which is a marker of brain injury, suggesting that EGb restores neurologic function during the treatment of depression in elderly patients and S100B participates in the therapeutic mechanism. EGb combined with depressive drugs plays synergistic role, and the time of onset of efficacy is faster than single antidepressants. PMID- 30278522 TI - Effects of postoperative non-steroidal anti-inflammatory drugs on long-term survival and recurrence of patients with non-small cell lung cancer. AB - Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used to relieve postoperative fever, surgery pain, and inflammation. In addition, NSAIDs have anticancer activity and may reduce the risk and mortality of several cancers. However, the association between postoperative NSAIDs and the clinical outcome of non-small cell lung cancer (NSCLC) patients with fever after surgery is not fully understood. We performed a retrospective study of NSCLC patients who underwent surgery between July 2011 and June 2012, aiming to evaluate the effect of postoperative NSAIDs on overall survival (OS) and progression-free survival (PFS). Differences in clinical data between the postoperative NSAIDs group and non-NSAIDs groups were analyzed by Chi-square tests. Kaplan-Meier curves method and Cox regression analysis were conducted for survival analysis. The primary and secondary endpoints were OS and PFS, respectively. This retrospective study included 347 NSCLC patients. There were no significant differences in the clinical characteristics between the NSAIDs group and non-NSAIDs group except for age (P = .024) and differential degree (P = .040). Administration of postoperative NSAIDs was related to longer OS (hazards ratio [HR] 0.528, 95% confidence interval [CI] 0.278-0.884, P = .006) and longer PFS (HR 0.557, 95% CI 0.317-0.841, P = .002) in the multivariate Cox regression model. Subgroup analysis showed statistically significant differences in elderly individuals, male subjects, low smoking index, poor differentiation, and non-adenocarcinoma subgroups, respectively. In conclusion, the administration of postoperative NSAIDs was related to longer OS and PFS in NSCLC patients with postoperative fever. PMID- 30278523 TI - Development and validation of the hypertensive intracerebral hemorrhage prognosis models. AB - To develop and validate the prognosis model of hypertensive intracerebral hemorrhage based on admission characteristics, which would be applied to predict the 3-month outcome.For developing the prognosis models, we studied data from 325 patients with retrospectively consecutive hypertensive intracerebral hemorrhage admitted between 2012 and 2016. The predictive value of admission characteristics was tested in logistic regression models, presenting 3-month outcome as the primary outcome. The performance of the models was tested by discrimination and calibration. After development, internal and external validations were used to test the function.The multivariate analysis of logistic regression indicated that age, Glasgow coma scale score, pupillary light reflex, hypoxemia, intracerebral hemorrhage volume, blood glucose, and D-dimer level were independent factors of the hypertensive intracerebral hemorrhage prognosis model. The prognosis model based on those admission risk factors worked well. The receiver operating characteristic curve was used to analyze the discriminant ability of model A, model A + B, and model A + B + C. Specifically, the area under the receiver operating characteristic curve increased from 0.816 (model A; 95% CI, 0.760 0.872) to 0.913 (model A + B + C; 95% CI, 0.881-0.946), and the models were not overoptimistic and were applicably confirmed by internal and external validations respectively.This prognosis model could be used to predict the prognosis of patients with hypertensive intracerebral hemorrhage early, simply and accurately, contributing to the clinical treatment eventually. PMID- 30278524 TI - Quantitative evaluation of myocardial layer-specific strain using two-dimensional speckle tracking echocardiography among young adults with essential hypertension in China. AB - The myocardial wall of the left ventricle is a complex, multilayered structure, which is altered in young adults with hypertension. The aim of this study was to define the characteristics of longitudinal and circumferential strain in young adults with hypertension.Two-dimensional speckle tracking echocardiography was used to analyze longitudinal and circumferential strain parameters in 67 young adults with hypertension, 70 older young adults with essential hypertension and 62 healthy adults.The global longitudinal strain (GLS) and global circumferential strain (GCS) was the highest at endocardium, and lowest at epicardium. A layer specific analysis of myocardial deformation in all adults revealed that all of the peak systolic longitudinal strain (LS) and the peak systolic circumferential strain (CS) in the endocardium, mid-myocardium and epicardium were gradually increased from the base to the apex. The peak systolic LS showed significant differences at basal, mid-ventricular, and apical level among normal adults, young NLVH (nonleft ventricular hypertrophy), and young LVH (left ventricular hypertrophy). In all the adults with hypertension, young adults were associated with higher peak systolic longitudinal strain values compared with older adults, but the small differences of LS may be meaningless in clinical settings. Between the young LVH and older LVH, the peak systolic CS showed significant differences except data of epicardium at basal and mid-ventricular level.This study provides reference values for layer-specific strain in young adults with hypertension. This detailed strain analysis provides layer-oriented information to reveal the different characteristics of circumferential and longitudinal strain in young adults with hypertension. This systolic dysfunction could be detected conveniently and accurately by 2DSTE. PMID- 30278525 TI - Epigenetic differences of chronic hepatitis B in different TCM syndromes: Protocol for a case-control, non-interventional, observational clinical study. AB - INTRODUCTION: Chronic hepatitis B is a serious disease causing serious harm to the human health. Chinese medicine has its unique advantages in the clinical prevention and treatment, while the syndrome of Chinese medicine lacks the understanding at the micro level. There are some theoretical commonalities between the epigenetics and traditional Chinese medicine (TCM) syndromes. The biological basis of chronic hepatitis B (CHB) syndrome differentiation from the perspective of epigenetics is of great significance to diagnose and prevent the diseases. METHODS: This protocol is a case-control, noninterventional, observational clinical study. Patients with CHB for spleen-stomach damp heat and liver depression and spleen deficiency, with 12 each and 11 healthy volunteers were recruited. Peripheral venous blood was collected from the participants. DNA methylated transferase, genomic DNA methylated spectrum, methylated DNA binding protein MeCP2, chronic infection of hepatitis B virus with methylated related proteins, and miRNA target genes were analyzed. OBJECTIVES: From the perspective of DNA methylation epigenetics, "DNA methylation-miRNA-Target gene" is the main line, which further reveals the essence of TCM syndrome. To improve the level of TCM clinical syndrome differentiation and the clinical efficacy of TCM, especially in the study of TCM syndromes of CHB, discovering its underlying biological signature is necessary.

PMID- 30278526 TI - Treatment with normobaric or hyperbaric oxygen and its effect on neuropsychometric dysfunction after carbon monoxide poisoning: A systematic review and meta-analysis of randomized controlled trials. AB - BACKGROUND: Carbon monoxide (CO) poisoning may result in acute neurological sequelae, cognitive sequelae, and delay neurological sequelae. The administration of hyperbaric oxygen (HBO) to prevent the development of delayed neurological sequelae in CO poisoning have extensively investigated but conflicting results have been reported. We performed a systematic literature review and meta-analysis of randomized controlled trials (RCTs) evaluating HBO treatment and its effect on neuropsychometric dysfunction after CO poisoning. METHODS: We searched Medline, Embase, Pubmed, and the Cochrane Register of Controlled Trials from inception to December 2017. Eligible studies compared HBO therapy with normobaric oxygen (NBO) in patients with CO poisoning. RESULTS: Six studies compared HBO with NBO in CO poisoning patients. Compared with patients treated with NBO, a lower percentage of patients treated with HBO reported headache (16.2% vs 16.5%, relative risk [RR] = 0.83, 95% CI = 0.38-1.80), memory impairment (18.2% vs 23.8%, RR = 0.80, 95% CI = 0.43-1.49), difficulty concentrating (15.0% vs 18.4%, RR = 0.86, 95% CI = 0.55-1.34), and disturbed sleep (14.7% vs 16.2%, RR = 0.91, 95% CI = 0.59 1.39). Two sessions of HBO treatment exhibited no advantage over one session. CONCLUSIONS: The meta-analysis indicated that compared with CO poisoning patients treated with NBO, HBO treated patients have a lower incidence of neuropsychological sequelae, including headache, memory impairment, difficulty concentrating, disturbed sleep, and delayed neurological sequelae. Taking into consideration the cost-effectiveness of one session of HBO, one session of HBO treatment could be an economical option for patients with CO poisoning with high severity. PMID- 30278527 TI - Immunohistochemical characterization of lymphangiogenesis-related biomarkers in primary and recurrent gliomas: A STROBE compliant article. AB - Glial tumors constitute the majority of primary intracranial brain tumors. The expression of specific markers of lymphangiogenesis in gliomas still remains unclear.A total of 40 surgical specimens from 20 patients with recurrent gliomas were included in the study. The expression of D2-40, vascular endothelial growth factor (VEGF)-C, VEGF-D, and VEGF receptor-3 (VEGR-3) was detected by immunohistochemistry (IHC). The clinicopathologic data (p53 and Ki67) were also collected and analyzed.At relapse malignant transformation rate was 65% (13/20 cases). D2-40, VEGF-C, VEGF-D, and VEGFR-3 were expressed in 20%, 30%, 60%, and 20% of primary and 45%, 30%, 75%, and 35% of recurrent glioma tumors (P < .01, P = 1.00, P = .03, P = .03). In 13 cases with increased malignancy grade, the expression of Ki67 and p53 were higher at relapse compared with the primary tumors (P = .001, P = .045). Multivariate survival analysis showed VEGF-D was an independent prognostic factor for malignant transformation (HR = 0.376, P = .045).Glioma is easy to relapse with tumor progression. VEGF-D was an independent prognostic factor for malignant transformation. PMID- 30278528 TI - Hyperthyroidism is not a significant risk of benign prostatic hyperplasia: A nationwide population-based study. AB - Benign prostatic hyperplasia (BPH) is a common disorder in the aging male population. Despite evidence that thyroid status impacts the prostate, the objective of this study was to examine whether patients with hyperthyroidism were at a greater risk for BPH.This study is a retrospective nationwide population based cohort study of the Chinese population. Data for this study were retrieved from the Taiwan National Health Insurance Research Database (NHIRD). Overall, 1032 male patients aged 40 years or older with hyperthyroidism diagnosed between 2000 and 2006 were included in the hyperthyroidism group, and 4128 matched controls without hyperthyroidism were included in the non-hyperthyroidism group. Both groups were monitored until the end of 2011. A Cox proportional hazards regression model was used to compute and compare the risk of BPH between study participants with and those without hyperthyroidism.Patients with hyperthyroidism exhibited a greater incidence of BPH (18.51% vs 15.53%) than did the controls. Furthermore, the hazard ratio (HR) of the hyperthyroidism group was 1.24 times that of the control group [95% confidence interval (95% CI 1.05-1.46)] signifying that there is a significant 24% increase in the risk of BPH with the presence of hyperthyroidism. This increased risk of BPH with hyperthyroidism, however, failed to remain significant (adjusted HR = 1.11, 95% CI = 0.94-1.3) after adjusting for covariates of age (adjusted HR = 2.72, 95% CI = 2.32-3.2), diabetes (adjusted HR = 1.4, 95% CI = 1.17-1.68), hypertension (adjusted HR = 1.74, 95% CI = 1.49 2.03), hyperlipidemia (adjusted HR = 1.25, 95% CI = 1.03-1.53), neurogenic bladder, cystitis (adjusted HR = 1.23, 95% CI = 0.58-2.59), urethral stricture (adjusted HR = 2.01, 95% CI = 0.28-14.47), urethritis (adjusted HR = 1.52, 95% CI = 0.72-3.21), and urinary tract infection (adjusted HR = 1.77, 95% CI = 1.31 2.39).After adjustment for comorbidities and covariates, hyperthyroidism was not found to be a significant risk factor of BPH in our male study subjects. Further research is warranted to validate our results and elucidate the association of the pathophysiology of these 2 diseases. PMID- 30278529 TI - Effects of the Chinese herb formula Yufeining on stable chronic obstructive pulmonary disease: A randomized, double-blind, placebo-controlled trial. AB - BACKGROUND: A Chinese herb formula Yufeining (YFN) has showed promise in the treatment of stable chronic obstructive pulmonary disease (COPD), less is known that the impact of YFN in combination with standard Western treatments on lung inflammation. This study evaluated the safety and efficacy of YFN as a treatment for stable COPD and as an anti-inflammatory agent. METHODS: Sixty patients with stable COPD were randomly assigned to two treatment groups (YFN treatment, N = 30; placebo treatment, N = 30). Both groups received inhaled steroids and bronchodilators during an 8-week intervention, and patient status was assessed at 8 weeks later and 4 months after treatment. The primary outcome included clinical efficacy. The secondary outcomes involved CAT score, mMRC grade, six-minute walking distance (6MWD). IL-8, TNF-alpha, IL-17A, LTB4, TGF-beta1 and CRP were also detection in peripheral serum, as well as adverse reaction conditions. RESULTS: The YFN group demonstrated a significant improvement in clinical efficacy (compare 89.3% to 63.3% in the placebo group; P < 0.05). CAT scores and mMRC grades significantly decreased (P < 0.05, P < 0.01), and 6MWD significantly increased (P<0.05), after YFN treatment. The levels of IL-8, TNF-alpha, LTB4 and CRP decreased significantly after 8 weeks of treatment compared to baseline levels in both groups. Only in the YFN treatment group, the levels of IL-17A decreased significantly after treatment compared to baseline levels (P < 0.05). No changes were observed inTGF-beta1 from pre-to post-treatment in either group (P > 0.05). Serum levels of IL-8, TNF-alpha, IL-17A, LTB4 and CRP decreased significantly after YFN treatment compared to the placebo group (P < 0.05). CONCLUSION: A combinatorial treatment approach with YFN, inhaled steroids and bronchodilators produced a clinically effective treatment for stable COPD, leading to a significant decrease in circulating inflammatory mediators. The study appeared YFN was safety. CLINICAL TRIAL REGISTRATION NUMBER: No. ChiCTR-IOR 17013577. PMID- 30278530 TI - Periocular triamcinolone acetonide injection for treating polypoidal choroidal vasculopathy concurrent with hemorrhagic retinal detachment. AB - To investigate the clinical efficiency of periocular triamcinolone acetonide (TA) injection for treating polypoidal choroidal vasculopathy (PCV) concurrent with hemorrhagic retinal detachment (HRD).Twenty-two cases confirmed with PCV concurrent with HRD characterized by massive subretinal hemorrhage and exudation presented to our department from January 2015 to May 2017 were included in this study. The initial vision varied from counting finger to 0.2. All cases were randomly divided into TA group (n = 12), which received periocular TA injection per month, and anti-VEGF group (n = 10), which were treated by anti-VEGF intravitreous injection per month. The patients were followed up for 6 months, in which fundus examination and visual acuity along with optical coherence tomography (OCT) were carried out.The treatment effect is divided into the following categories. Cure was defined as the elimination of subretinal hemorrhage and exudation accompanied by retinal edema and choroidal neovascularization (CNV) extinction and rise of visual acuity. Improvement was characterized by alleviation of subretinal hemorrhage and exudation accompanied by retinal edema and CNV reduction and rise of visual acuity. Ineffective means remained subretinal hemorrhage and exudation in fundus and no improvement of visual acuity, and polypoid lesions in OCT images. Among the 12 cases in TA group, 1 case was treated by periocular injection of TA twice, and 11 cases were treated by 3 times injection. After that, 3 cases (25%) were cured, 8 cases (66.7%) got improvement, and only 1 case (8.3%) showed no response. Although among 10 cases in the anti-VEGF group, 3 cases were treated by anti-VEGF intravitreous injection twice. Seven cases were treated by 3 times injection. After that, 4 cases (40%) got improvement, and the other 6 case (60%) showed no response. All patients showed no recurrence in the 6-month follow-up. No complications were noticed under periocular injection or intravitreous injection.Periocular TA injection is effective for treating PCV concurrent with HRD. PMID- 30278531 TI - The reasons and clinical treatments of postoperative relapse of Pott's disease. AB - Literature about postoperative relapse of Pott's disease is rare. Accordingly, the risk factors and clinical treatments for postoperative relapse of Pott's disease remain controversial. In order to evaluate the clinical outcomes of surgical treatment of postoperative Pott's disease relapse, and to investigate its optimal therapeutic procedures with respect to focal characteristics, we performed a retrospective review of clinical and radiographic data that were prospectively collected between July 2008 and May 2014 from 753 consecutive spinal tubercular patients including 67 patients who were diagnosed and treated as postoperative relapse of Pott's disease in our hospital. Apart from 9 patients being treated conservatively, the remaining 58 cases received surgery in our series. Specifically, 12 cases underwent anterior debridement, interbody fusion with instrumentation; 15 cases received posterior instrumentation anterior debridement, and bone grafting; 10 cases underwent posterior decompression, bone grafting, and instrumentation; 7 cases with debridement, 5 with debridement and sinus resection. Nine cases received percutaneous drainage and low-dose local continuous chemotherapy. Clinical outcomes before and after treatment were evaluated with statistical analysis based on hematologic and radiographic examinations, bone fusion, and neurologic status. Patients were followed-up for a mean of 39.2 +/- 8.2 months (range, 24-60 months). Postoperatively, the erythrocyte sedimentation rate (ESR) became normal within 4-6 months in all patients, and solid bone fusion was achieved within 8 months. Patients exhibited significant improvements in neurological deficits postoperatively, while the visual analog scale for pain showed significant improvements in all patients at final follow-up. The outcomes of follow-up showed that the reasons for postoperative relapse of Pott's disease were multiple. Individualized therapeutic methods should be chosen in accordance with the patient's general condition, recurrence focal characteristic, surgeon's experience, but above all is administration of appropriate chemotherapy.

AB - RATIONALE: The present study explored the relationship between the adenosine triphosphate (ATP)-binding cassette A1 (ABCA1) gene, atherosclerosis, and cerebral infarction. The diagnosis and treatment ideas of stroke caused by Tangier disease via the summary of the diagnosis and treatment process of one case with juvenile stroke were explored. The relevant literature on the clinical manifestations, laboratory examinations, and treatment of Tangier disease was reviewed. PATIENT CONCERNS: The brain magnetic resonance imaging (MRI) of a juvenile man with acute onset of sudden right limb weakness and speechlessness revealed infarct lesions. The laboratory tests found low serum high-density lipoprotein (HDL), while further genetic testing identified ABCD1 gene mutation. The mother also carried the mutant gene. DIAGNOSES: Tangier disease was diagnosed. INTERVENTIONS: Statin treatment was administered for platelet aggregation. OUTCOMES: After 3 years of follow-up, the patient was declared to be in a stable condition. LESSONS: ABCA1 gene mutation caused early onset of atherosclerosis, leading to the occurrence of cerebral infarction. The cerebral infarction associated with reduced high-density lipoprotein (HDL), was under intensive focus with respect to ABCA1 gene. Child and Juvenile stroke patients with low HDL should not be excluded from the possibility of Tangier disease. PMID- 30278533 TI - Lumbar intraspinal microcystic/reticular schwannoma: Case report and literature review. AB - RATIONALE: Microcystic/reticular schwannoma (MRS) is a rare histological variant of schwannoma which was initially described in 2008 with a predilection for the visceral organs. This distinct tumor had been reported to mainly affect gastrointestinal tract, subcutaneous and soft tissue, various glands and head and neck region. However, MRS involving spine is extremely rare. PATIENT CONCERNS: The authors report the first case of MRS occurring in the lumbar (L) spinal canal of a 40-year-old male who presented with continuous pain and numbness in both feet for 2.5 years. Physical examination revealed weakness of lower extremities and hyperalgesia of both feet. DIAGNOSES AND INTERVENTIONS: The findings of pre operative investigation were suspicious for either a schwannoma or a spinal meningioma. Accordingly, total laminectomy, complete tumor resection, instrumentation and spinal fusion were performed. Post-operative histopathologic examination revealed a well-encapsulated neoplasm with reticular and microcystic growth pattern. Antoni A and Antoni B regions, Verocay bodies and hyalinized blood vessels were observed. And cytologic atypia, necrosis or mitosis was absent. Immunohistochemically, the tumor cells showed strong and diffuse positivity for S-100 as well as SOX 10. Therefore, a histopathological diagnosis of MRS was finally made. OUTCOMES: The patient remains well with no evidence of recurrence at a 22-month follow-up. LESSONS: This is the first case of MRS which is located in the L spinal canal. Awareness of this distinctive entity is helpful in preventing diagnostic pitfalls and making correct treatment strategies. PMID- 30278534 TI - Von Hippel-Lindau with early onset of hemangioblastoma and multiple drop metastases like spinal lesions: A case report. AB - RATIONALE: Hemangioblastoma is a rare tumor of the central nervous system (CNS). It is usually observed in patients with von-Hippel Lindau (VHL). The peak age for hemangioblastoma is between 20 and 50 years of age with very few cases over 65 or below 18 years of age. PATIENT CONCERNS: We report a female with a rare VHL mutation (c.337C>T) who was diagnosed with multifocal CNS hemangioblastoma at a very young age. DIAGNOSIS: At 17-years of age, she presented with obstructive hydrocephalus due to large cystic cerebellar mass. Imaging showed multiple lesions resembling drop metastases throughout her spinal cord. Immunohistochemistry of the resected tumor confirmed the pathological diagnosis of hemangioblastoma (World Health Organization Grade 1). INTERVENTIONS AND OUTCOME: She was treated with multi-stage resection of her primary and drop- metastasis like disease. She presented six months later with retinal hemangioblastoma while her other lesions were stable. She presented with multiple CNS and eye hemangioblastomas after failing to follow up for 2 years. Subsequently, Everolimus was started to treat her systemic disease. LESSONS: The unique feature of our case is the presence of multiple drop-metastases like spinal lesions, which has not been reported in the literature to be associated with hemangioblastoma. PMID- 30278535 TI - Recurrent cerebral microbleeds with acute stroke symptoms: A case report. AB - RATIONALE: Cerebral microbleeds are lesions that appear as round low signal intensity areas with a diameter of 2-5 mm on gradient echo T2-weighted sequence magnetic resonance imaging. Cerebral microblees are hemorrhages found in the brain parenchyma and they are caused by the extravasation of the blood. Although more patients with ischemic stroke are found to have cerebral microbleeds, only a few studies have evaluated other neurologic abnormalities outside of cognitive dysfunction due to cerebral microbleeds. PATIENT CONCERNS: A 73-year-old female patient had only a lacunar infarction with the development of a new microbleed whenever a new neurologic symptom occurred, without the occurrence of acute ischemic stroke. DIAGNOSES: A 73-year-old female patient diagnosed symptomatic cerebral microbleeds. INTERVENTIONS: Brain magnetic resonance imaging was taken within a few hours of the occurrence of a new symptom and we confirmed increased cerebral microbleeds in the ventral-posterolateral area of the thalamus, consistent with the symptoms. OUTCOMES: This case study is meaningful because it proves that repeated occurrences of cerebral microbleeds in a specific area can induce acute ischemic stroke-like symptoms. LESSONS: Cerebral microbleeds have been considered to be asymptomatic lesions thus far. However, recent studies have reported the association of cerebral microbleeds with neurological symptoms including cognitive dysfunction. This study confirmed the presence of newly formed cerebral microbleeds through imaging follow-ups whenever a symptom occurred. PMID- 30278536 TI - Change in lipid profile and risk of new-onset atrial fibrillation in patients with chronic heart failure: A 3-year follow-up observational study in a large Chinese hospital. AB - In chronic heart failure (CHF), new-onset atrial fibrillation (AF) is associated with increased morbidity and mortality. We aimed to evaluate the influence of dyslipidemia on the incidence of new-onset AF in patients with CHF.In this single center observational study, 308 patients with CHF and no history of AF were followed-up for 3 years. Of the 291 patients who attended the 1-year follow-up, 78 had developed AF (AF group; 10 deaths), while 213 had not (sinus rhythm [SR] group). Changes in lipid profile (DeltaTC for total cholesterol and DeltaLDLc for low-density lipoprotein cholesterol) were analyzed.The groups differed significantly regarding the decrease in lipid levels from baseline to the 1-year follow-up (AF vs SR: for DeltaLDLc, 23.35 vs 7.80 mg/dL, P = .02; for DeltaTC, 23.95 vs -2.76 mg/dL, P = .001). At the 3-year follow-up, new-onset AF was noted in 21 of the 188 living patients in the SR group. Cox proportional hazards analysis revealed DeltaLDLc and DeltaTC as independent risk factors for new-onset AF (hazard ratio, 1.018 and 1.013, respectively, per standard deviation increment), with higher incidence of new-onset AF for DeltaTC > 9.65 mg/dL (P = .02) and for DeltaLDLc > 9.73 mg/dL (P = .005).In CHF, pronounced decrease in LDLc and TC is associated with new-onset AF. PMID- 30278537 TI - Validation of a self-reported work disability questionnaire for ulcerative colitis. AB - Ulcerative colitis (UC) may severely limit patients' capacity to work. Recently, we validated a work disability questionnaire (WDQ) for Crohn disease. As UC shares clinical characteristics with Crohn disease, we hypothesized that the questionnaire might also be useful for UC. The study was aimed to validate the WDQ for use in UC.Consecutive patients with UC (n = 142, 67 women; age 48 +/- 1) completed the UC-WDQ and the inflammatory bowel disease questionnaire-9 (IBDQ-9), and EuroQoL-5D quality-of-life questionnaires. Validation of the UC-WDQ included an assessment of its construct validity, including: discriminant validity, convergent validity, and reproducibility (test-retest). We also calculated the intraclass correlation and the Cronbach alpha.The UC-WDQ is a valid and reliable tool for measuring work disability in patients with UC. PMID- 30278539 TI - Is Internet overuse associated with impaired empathic ability in Korean college students? AB - The purpose of the present study was to determine whether Internet overuse was associated with empathic ability in college students.A total 261 participants (145 males and 116 females; mean age of 21.93 years) completed Empathy Quotient (EQ), Young's Internet Addiction Test (IAT), and questionnaires about demographic data and internet using patterns.Of these 261 subjects, 85 (32.5%) were categorized as over-users. There was no significant difference in EQ total score between the over-user group and the average user group. The over-user group had lower scores of Social Skills than the average user group in subscale profiles. The over-user group stayed longer in cyberspace than the average user group. EQ score was found to have positive correlation with time spent in Internet use and the number of close friends.Results of the present study suggest that conventional Internet use is positively associated with empathic ability in interpersonal relationships. Therefore, such positive association between Internet use and empathic ability should be considered when evaluating possible problematic internet use. PMID- 30278538 TI - Relationship between short telomere length and stroke: A meta-analysis. AB - BACKGROUND: Several epidemiological studies had been carried out in different population cohorts to estimate the relationship between the shortened telomere length and stroke. However, the results still remained dispute. Consequently, we conducted this meta-analysis to estimate the relationship between them. METHODS: PubMed, EMBASE, and Web of Science were systematically searched for related articles to evaluate the association between "stroke" and "telomere length. STATA 12.0 software was used to perform the meta-analysis. The Cochran Q test and inconsistency index (I) were used to assess the heterogeneity. Begg funnel plot and Egger test were used to assess publication bias. RESULTS: The meta-analysis was composed of 11 studies, consisting of 25,340 participants. We found a significant relationship between shortened telomere length and stroke (OR: 1.50, 95% CI: 1.13-2.0; P = .005); however, in the prospective and retrospective study subgroup, we did not find a statistical significant relationship between shortened telomere length and stroke (the prospective subgroup: OR: 1.41, 95% CI: 1-1.98; P = .051) (the retrospective subgroup: OR: 1.89, 95% CI: 0.96-3.72; P = .067). PMID- 30278540 TI - Lower circulating angiotensin II levels are related to the severity of preeclampsia and its risk as disclosed by a specific bioassay. AB - Preeclampsia is characterized by an increased sensitivity to angiotensin II (Ang II). We herein assessed whether serum Ang II levels measured by a new developed bioassay are associated with preeclampsia, its severity, and the risk for developing this disease.Using a cross-sectional design, we studied 90 pregnant women (30 healthy pregnant and 60 with preeclampsia [30 with- and 30 without severe features]). We also used a nested case-control study with 30 women who eventually developed preeclampsia and 31 normotensive controls. Serum samples were collected at diagnosis of preeclampsia or at 4-week intervals (from weeks 12th to 36th). Ang II was measured using a bioassay.At diagnosis of preeclampsia, serum Ang II concentrations were significantly lower in preeclampsia without and with severe features (P = .001 and P < .001, respectively) than in healthy pregnancy. In addition, Ang II was different in preeclampsia with severe features than in those without severe features (P = .048). Women who subsequently developed preeclampsia had lower Ang II levels than women with normal pregnancies, and these changes became significant at 24 weeks onward. The risk to developing preeclampsia was higher among women with Ang II concentration values in the lowest quartile of the control distribution from 12 weeks onward (odds ratio ranging from 3.8 [95% CI 1.3-11.1] to 6.5 [95% CI 1.6-26.9]).We concluded that concentrations of Ang II are markedly diminished at diagnosis of preeclampsia and are closely associated with the severity of disease. Changes in circulating levels of Ang II precede the clinical presentation of preeclampsia. PMID- 30278541 TI - Repeated resection-associated breast angiosarcoma: A case report. AB - RATIONALE: As a very rare vascular tumor, breast angiosarcoma (AS) can be divided into primary and second breast AS. However, the latter is slightly more commonly detected in clinical practice. Radiation post mastectomy is the common cause for the secondary breast AS, and although there are other reasons, it is still quite rare. In the present study, we reported a rare case of breast AS and summarized the relevant literatures so that to conduce to diagnose AS. PATIENT CONCERNS: A 50-year-old female with a history of right breast neoplasm was treated with repeat lumpectomy for 4 times during 8 years. DIAGNOSES: Mammogram and ultrasound examination demonstrated a possible malignancy (BIRADS-4B and BI-RADS-4C, respectively). Immunohistochemically positive for endothelial markers CD31, CD34, ERG, and FVIII-R-Ag. INTERVENTIONS: The patient underwent a right mastectomy with sentinel lymph node biopsy by our multidisciplinary team and no other therapy was given postsurgery. OUTCOMES: The patient had no recurrence after 3 months. LESSONS: Based on our findings, we concluded that repeated resection might be a risk factor for the breast AS, especially for a gradual pathological evolution from benign to malignant. This case showed a very rare cause for angiomatosis of breast, and the patient had a successful outcome after a simple mastectomy. PMID- 30278542 TI - Surgical management of retroperitoneal schwannoma complicated with severe hydronephrosis: A case report. AB - RATIONALE: Schwannomas are usually benign tumors arising from well-differentiated schwann cells, which rarely occur in the retroperitoneal space. The lack of specific signs and radiologic imaging characteristics makes preoperative diagnosis rather difficult. Most retroperitoneal schwannomas are benign and the primary treatment choice for retroperitoneal schwannomas is surgical excision, however, the involvement of the urinary system is scarcely reported. PATIENT CONCERNS: A 34-year-old woman presented with progressive left abdominal pain and rebound abdominal mass at the left lower quadrant for 1 month. Radiological imaging suggested capsulated solid mass with cystic and necrotic areas in the retroperitoneum accompanied by severe left kidney hydronephrosis and preoperative biopsy result was inconclusive. DIAGNOSES: We believe this is a rare case of retroperitoneal schwannoma complicated with severe hydronephrosis. INTERVENTIONS: After preparation, the patient underwent laparoscopy exploration and converted to open surgical exploration. The patient accepted complete surgical excision of the retroperitoneal tumor and left kidney. Postoperative pathology diagnosis of the mass was proven to be benign retroperitoneal schwannoma. OUTCOMES: Postoperative course of the patient was uneventful and the left abdominal pain was greatly improved. After 12-month follow up, no evidence of recurrence or any other complication including renal failure was observed. LESSONS: Preoperative imaging and preoperative ultrasound-guided biopsy are helpful to make accurate diagnosis. The final diagnosis is based on postoperative histological and immunohistochemical findings. The primary treatment option is complete surgical resection of the retroperitoneal schwannoma and the involved upper urinary system when severe hydronephrosis occured. Local recurrence and overall survival are closely correlated with negative resection margins and pathology types. PMID- 30278543 TI - Correlations of DAPT score and PRECISE-DAPT score with the extent of coronary stenosis in acute coronary syndrome. AB - Dual antiplatelet therapy (DAPT) score and PRECISE-DAPT score were recommended for decision making of optimal DAPT in discriminating the risk of thrombosis and bleeding. But the relationships between 2 scoring tools with the extent of coronary stenosis have not been established.We retrospectively enrolled 359 patients of acute coronary syndrome (ACS) who received percutaneous coronary intervention. Both DAPT score and PRECISE-DAPT score were calculated, and patients were divided by their recommended cut-offs. Gensini score and triple vessel disease (3-VD) were chosen to evaluate the severity of coronary stenosis.Overall, 54.9% and 10.0% of the patients had higher DAPT score (>=2) or PRECISE-DAPT score (>=25). Patients with higher DAPT score had increased stent counts, total length of stents, Gensini score, and proportion of 3-VD, but decreased minimum diameter of stent. But these differences were not found in PRECISE-DAPT subgroups. When divided into quartiles of both scoring systems, the highest Gensini score and proportions of 3-VD were found in the fourth quartile of both DAPT score and PRECISE-DAPT score. Moreover, both DAPT score and PRECISE DAPT score were independent risk factors of Gensini score after adjustment (P < .001 and P = .047). Furthermore, an increase of 1 point of DAPT score and 5 points of PRECISE-DAPT score resulted by 51% (odds ratios [OR]: 1.51, 95% confidence interval [CI]:1.19-1.91, P = .001) and 34% (OR: 1.34, 95% CI: 1.11 1.62, P = .003) increase in risk of 3-VD after adjustment.Both DAPT score and PRECISE-DAPT score were independently associated with the degree of coronary stenosis in patients with ACS. PMID- 30278544 TI - Effect of preemptive dezocine before general anesthesia on postoperative analgesia in patients undergoing laparoscopic cholecystectomy: A prospective observational study. AB - Dezocine is proposed as an adjunctive analgesic for postoperative pain control. This randomized, double-blind, controlled study aimed to investigate the effect of preoperative Dezocine therapy on postoperative pain following laparoscopic cholecystectomy as well as the underlying mechanisms.Eighty patients scheduled for laparoscopic cholecystectomy were randomly allocated into 2 groups as follows: patients in Group D received Dezocine 0.15 mg/kg before anesthesia induction and patients in Group S received same volume of saline. The pain intensity, sedation score, sufentanil-based patient-controlled analgesia (PCA) consumption were recorded for 24 hours after surgery. Plasma concentrations of norepinephrine and serotonin were also measured.During the first 24 hours after surgery, the patients in Group D experienced lower pain score assessed by numerical rating scale (NRS) at 3 hours (rest: P = .038; movement: P = .036), 6 hours (rest: P = .038; movement: P = .036), 12 hours (rest: P = .038; movement: P = .036), and 24 hours (rest: P = .038; movement: P = .036). Dezocine also decreased the sedation levels at 5 minutes (P = .031) after arrival at the PACU. Sufentanil-based PCA consumption in Group D was decreased when compared with Group S in the second to fourth phase after surgery (6-12 hours: P = .017; 12-18 hours: P = .003; 18-24 hours: P = .039). Plasma norepinephrine and serotonin concentrations were higher in the Group D at 24 hours after surgery (norepinephrine: P = .009, serotonin: P = .042). In addition, Group D showed less incidence of nausea/vomiting (P = .032) as well as a higher postoperative satisfaction score after surgery (P = .017).In conclusion, preemptive Dezocine administration is suggested to be useful for the management of postoperative pain in short-lasting surgery such as laparoscopic cholecystectomy. PMID- 30278545 TI - Characteristics of overlooked synchronous gastric epithelial neoplasia after endoscopic submucosal dissection. AB - Since endoscopic submucosal dissection (ESD) has been accepted as the treatment of choice for early gastric cancer (EGC) without risk of lymph node metastasis, synchronous gastric epithelial neoplasia is no longer rare in the clinical practice. Knowledge about the characteristics associated with synchronous gastric epithelial neoplasia is of great importance to prevent delayed diagnosis.Between November 2008 and December 2014, a retrospective study was conducted in a single tertiary referral hospital. Consecutive patients who underwent ESD due to EGC or high-grade dysplasia were analyzed to evaluate the incidence of synchronous gastric epithelial neoplasia and the factors associated with synchronous and overlooked synchronous lesions.A total of 488 patients were analyzed in this study. Synchronous lesions were found in 59 patients (12.1%) during the mean 37.7 months of follow-up. Among 77 synchronous lesions, 25 lesions (32.4%) were overlooked at the time of initial ESD. Age of >= 65 years, moderate to severe endoscopic atrophic gastritis, and elevated morphology of primary lesions were associated with synchronous gastric epithelial neoplasia. An important factor associated with overlooked lesions is the non-elevated morphology of lesions.Careful endoscopic examination of the whole stomach is necessary in patients who are older and who have moderate to severe atrophic gastritis and elevated morphology of lesions to prevent delayed diagnosis of synchronous gastric epithelial neoplasia, especially non-elevated lesions. PMID- 30278546 TI - Association between NR3C1 rs41423247 polymorphism and depression: A PRISMA compliant meta-analysis. AB - BACKGROUND: A dysfunction of the hypothalamic-pituitary-adrenal (HPA) axis is closely related to the occurrence of depression. The glucocorticoid receptor, also known as the nuclear receptor subfamily 3, group C, member 1 (NR3C1), provides negative feedback to the HPA axis by binding to glucocorticoids. Some studies have demonstrated an association between the NR3C1 rs41423247 polymorphism and depression, but results from other studies have been controversial. METHOD: In this study, the association between the NR3C1 rs41423247 polymorphism and depression was evaluated by a meta-analysis using the RevMan 5.3 software, and the Stata 10.0 software was used for sensitivity analysis and publication bias test. According to the inclusion criteria, related studies in databases were retrieved and screened. RESULTS: In total, 9 articles were selected, including 1630 depressed patients and 3362 controls. The meta analysis showed that homozygous mutation of NR3C1 rs41423247 was associated with depression in the total population (OR = 0.77, 95% CI = 0.64-0.94, P = .01) and in Caucasians (OR = 0.78, 95% CI = 0.63-0.96, P = .02). CONCLUSION: This meta analysis demonstrates that the NR3C1 rs41423247 homozygous mutation may be a risk factor for depression. PMID- 30278547 TI - Hemodynamic management of a patient with a huge right atrium myxoma during thoracic vertebral surgery: A case report. AB - RATIONALE: Myxoma is the most common primary benign cardiac tumor, which could lead to some fatal complications because of its strategic position. PATIENT CONCERNS: The patient was admitted to our hospital due to sudden onset of palpitation, chest tightness, mild fever, night sweats, accompanied with bilateral lower extremities adynamia, and paralysis for 5 days, but no obvious syncope and edema. DIAGNOSES: Transthoracic echocardiography showed a giant mobile myxoma (72 * 58 mm) in the right atrium (RA). Magnetic resonance imaging revealed an erosive space-occupying lesion located between the first and third thoracic vertebrae. INTERVENTIONS: Thoracic vertebral lesions were resected immediately to rescue the incomplete paraplegia. After the patient was placed in the prone position, significant hemodynamics changes were observed due to the displacement of the huge RA myxoma. OUTCOMES: Stable hemodynamics was maintained during the operation through control of fluid infusion combined with vasoactive drugs. LESSONS: Change in body position may lead to obstruction of intracardiac blood flow in patients with giant myxoma. This clinical manifestation is rarely reported. PMID- 30278548 TI - Tracheal diverticula: A retrospective analysis of patients referred for thoracic CT. AB - To assess the prevalence of tracheal diverticula (TD) in patients referred for thoracic Computed Tomography (CT).1679 consecutive patients subjected to thoracic CT examination for different causes, from January to June 2017, were included in this cohort study. CT was performed with a 64 slice CT, using a standard protocol and Multiplanar Reformat Images (MPR). A TD was defined as a thin-walled air sac at the paratracheal wall with a communication with the tracheal lumen. Congenital or acquired nature of TD was determined by the anatomical location, being usually the congenital ones located 4 to 5 cm below the vocal cords or a few centimeters above the carina in the right paratracheal area, whereas acquired ones were located at the level of the thoracic inlet, in the posterolateral tracheal wall. Presence of TD was assessed and their number and size recorded based on 2 axial diameters and size of neck.One or more TD were found in 96 patients (5.7% of sample), with a slight preponderance (65%) in male gender. Globally, 124 TD were detected; they were solitary in 75% of cases, double in 20.8%, and in about 4.2% they were triple. Average size of the TD was 1.3*4.9 mm with a mean width of the neck of 1.9 mm. The peak of prevalence (9%) was in patients belonging to the fourth-decade group (see ). According to their anatomical location, the majority (97.6%) of TD were acquired in nature and devoided of specific symptoms (see below).(Table is included in full-text article.)Acquired TD were detected in about 1 out of 20 of thoracic CTs and were usually incidentally. Our findings show a slightly higher frequency than previously reported. The most frequent presentation was in male and as a single entity. Clinically, TD was not associated with specific symptoms, in particular with chronic cough or Chronic Obstructive Pulmonary Disease (COPD). PMID- 30278549 TI - A rare myxoma-like right atrial thrombus causing syncope: A case report. AB - RATIONALE: Syncope is a complicated clinical condition involving various diseases. Syncope due to myxoma-like right atrial thrombus is rarely seen in patient without structural heart disease. PATIENT CONCERNS: A 61-year-old ambulant old male visited our emergency department for sudden syncope. DIAGNOSES: After the exclusion of neurological and coronary diseases, a right atrial block mass with a stalk connected to the atrial septum was accidentally found by echocardiography. Pulmonary embolism was subsequently revealed by computed tomographic pulmonary angiography. Atrial myxoma was initially suspected and surgical removal was conducted. Surprisingly, histological examination showed that the pedicled block mass was actually thrombus. INTERVENTIONS: The myxoma like right atrial thrombus and the emboli in the bilateral pulmonary trunks were resected. This patient received anticoagulant treatment with warfarin for 6 months additionally. OUTCOMES: The patient was successfully discharged and being continually followed. CONCLUSION: This patient had a past medical history of right femoral neck fracture, which might be responsible for the formation of the myxoma-like right atrial thrombus. We should always consider echocardiography examination in syncope patient at risk of thrombus formation. PMID- 30278551 TI - Sarcomatous intrahepatic cholangiocarcinoma: Case report and literature review. AB - RATIONALE: Sarcomatous intrahepatic cholangiocarcinoma is a rare histological variant of cholangiocarcinoma (ICC). Previous medical literature has not mentioned the prevalence of this kind of disease, but a poorer prognosis than that of ordinary ICC was indicated. The diagnosis of the sarcomatous ICC is established on histopathological and immunohistochemical examinations. In this article, we present a new case of a patient with sarcomatous ICC who had no radiographic sign of intrahepatic tumor preoperatively. PATIENT CONCERNS: A 63 year-old man was noted with cholecystolithiasis and right upper abdominal pain. Liver function was within normal limits, although the gamma-glutamyl transpeptidase level was elevated. Serum carbohydrate antigen 19-9 level was elevated. Radiography showed atrophy of the left lobe of the liver, high intensity signals on T1 weighted images, and low/high-intensity signals on T2 weighted images in hepatic ducts. DIAGNOSES: The preoperative diagnoses were hepatolithiasis, choledocholithiasis, and cholecystolithiasis. INTERVENTIONS: Exploratory laparotomy, adhesion release, cholecystectomy, choledocholithotomy, and T tube drainage were performed. During the surgery, an ill-defined tumor was detected on the atrophic left lateral lobe of the liver. Hepatic left lateral lobectomy was performed to remove the mass. OUTCOMES: The final diagnosis of sarcomatous ICC was made by histopathology after surgery. No evidence of local recurrence or distant metastasis was noted on imaging during follow-up. LESSONS: Although rare, sarcomatous ICC does exist in patients presented with cholecystolithiasis and liver atrophy. Surgeons should be aware of the existence of sarcomatous ICC due to the poor prognosis. We recommend that multidisciplinary approaches may be key to improve prognosis, including adjuvant chemotherapy or radiotherapy. PMID- 30278550 TI - Pernicious anemia associated with cryptogenic cirrhosis: Two case reports and a literature review. AB - RATIONALE: Pernicious anemia (PA) is an autoimmune gastritis that results from the destruction of gastric parietal cells and the associated lack of an intrinsic factor to bind ingested vitamin B12. While an association between PA and various liver diseases has been rarely reported, reports of associated diseases include primary biliary cholangitis, autoimmune hepatitis, and Interferon-treated hepatitis C. We present 2 cases of PA associated with cryptogenic cirrhosis (CC), which has not been previously reported in the literature. PATIENT CONCERNS: A 42 year-old man presented with fatigue, pallor, and sustained abdominal distension that had persisted for 15 days. An 87-year-old man was admitted to the hospital for an unsteady gait and loss of appetite that had persisted for 20 days. DIAGNOSES: Symptoms, laboratory tests, and imaging findings for both patients were indicative of PA and CC.Both had neurological and psychiatric symptoms during hospitalization that were ultimately linked to a vitamin B12 deficiency but not hepatic encephalopathy. INTERVENTIONS: Both patients received intramuscular injections of vitamin B12. OUTCOMES: Hemoglobin levels of the 2 patients increased gradually, and their neurological symptoms were alleviated. LESSONS: PA associated with a liver disease is rare, and the underlying mechanism can only now be clarified. We speculate that autoimmune dysfunction and chronic vitamin B12 deficiency caused by PA might be unique causes of liver cirrhosis. Additional investigations are needed to verify these findings. PMID- 30278552 TI - Chronic kidney disease correlates with increased risk of pulmonary tuberculosis before initiating renal replacement therapy: A cohort study in Taiwan. AB - This study aimed to assess the association between chronic kidney disease (CKD) and the risk of pulmonary tuberculosis (TB) before initiating renal replacement therapy (RRT) in Taiwan.Total 16,052 subjects newly diagnosed with CKD between 2000 and 2012 were included in the CKD group, and 31,949 randomly selected subjects who did not have CKD formed the non-CKD group. Subjects with a history of pulmonary TB or RRT, including dialysis and renal transplantation, before the index date were excluded. We determined the incidence of pulmonary TB at the end of 2013. A multivariable Cox proportional hazards regression model was used to assess the hazard ratio (HR) and 95% confidence interval (CI) for the risk of developing pulmonary TB associated with CKD.The overall incidence of pulmonary TB was 1.47-fold greater in the CKD group compared to that in the non-CKD group (4.94 vs 3.35 per 1000 person-years, 95% CI 1.39, 1.56). Multivariable Cox proportional hazards regression analysis showed that the adjusted HR of pulmonary TB was 1.45-fold higher in the CKD group (95% CI 1.27, 1.64) than in the non-CKD group. Male sex (adjusted HR 2.04), age (increase per one year, adjusted HR 1.05), chronic obstructive pulmonary disease (adjusted HR 1.54), and diabetes mellitus (adjusted HR 1.34) were also associated with pulmonary TB.CKD is associated with an increased risk of developing pulmonary TB before the initiation of RRT. PMID- 30278553 TI - The elevated prevalence of risk factors for chronic liver disease among ageing people with hemophilia and implications for treatment. AB - Chronic liver disease (CLD) is frequently seen in the hemophilia population. The ADVANCE Working Group conducted a cross-sectional study in which people with hemophilia (PWH) aged >=40 years were included. This study aimed to assess the associations between CLD and its risk factors using data from the H3 study, and to suggest implications for optimal care.Data from 13 European countries were collected at a single time-point (2011-2013). Univariate and multivariate logistic regression (MLR) analyses were performed.A total of 532 PWH were included with either hemophilia A (n = 467) or hemophilia B (n = 65). A total of 127 (24%) were diagnosed with CLD. Hepatitis C virus (HCV), human immunodeficiency virus (HIV), total cholesterol, and severe hemophilia were significant risk factors in univariate logistic regressions. In MLR, HCV Ab+/PCR+ (OR = 17.6, P < .001), diabetes (OR = 3.0, P = .02), and HIV (OR = 1.9, P = .049) were positively associated with CLD. Total cholesterol (OR = 0.6, P = .002) was negatively associated with CLD. We found no evidence of interaction effects among the explanatory variables. No significant associations with age and type of or severity of hemophilia were observed in MLR.The main risk factors for CLD in this European cohort also apply to the general population, but the prevalence of HCV and HIV is considerably larger in this cohort. With new and improved treatment options, intensified eradication therapy for HCV seems justified to prevent CLD. Similarly, intensified monitoring and treatment of diabetes seem warranted. PMID- 30278554 TI - Effect of Tai Chi for post-stroke mental disorders and sleep disorders: A protocol for systematic review and meta-analysis. AB - BACKGROUND: Post-stroke mental disorders (PSMDs) and post-stroke sleep disorders (PSSDs) are very common in stroke patients. Recently, Tai Chi (TC) as a form of Chinese traditional mind-body exercise has been gradually applied to stroke rehabilitation although its efficacy for PSMD and PSSD varies across different studies. The aim of this study is to explore the therapeutic effect of TC training for PSMD and PSSD. METHODS: This review will only include randomized controlled trials (RCTs). Search strategy will be performed in 3 English databases, 4 Chinese databases, and the WHO International Clinical Trials Registry Platform. All English or Chinese RCTs, published from inception to February 28, 2019, will be sought. Two reviewers will screen, select studies, extract data, and assess quality independently. Primary outcomes are clinical scales, mainly including "Hamilton depression scale," "Hamilton anxiety scale," and "Pittsburgh sleep quality index." The methodological quality including the risk of bias of the included studies will be evaluated using a modified assessment form, which is based on Cochrane assessment tool and Physiotherapy Evidence Database scale. Review Manager Software (Revman5.3) will be used for heterogeneity assessment, generating funnel-plots, data synthesis, subgroup analysis, and sensitivity analysis. We will use GRADE system to evaluate the quality of our evidence. RESULTS: We will provide some more practical and targeted results investigating the effect of TC exercise for PSMD and PSSD in the current meta-analysis. Meanwhile, we will ascertain study progress of TC for PSMD and PSSD and find out defects or inadequacies of previous studies, so that future researchers could get beneficial guidance for more rigorous study. CONCLUSION: The stronger evidence about TC's rehabilitative effect and safety for PSMD and PSSD will be provided for clinicians and policymakers. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42018106608. ETHICS AND DISSEMINATION: We do not apply for formal ethical approval from ethics committee because all of the study data in our review will be obtained in an anonymous way.

PMID- 30278555 TI - An interactive assistant for patients with cardiac implantable electronic devices: A study protocol of the LUCY trial. AB - Patients with chronic heart failure (CHF) and reduced left ventricle ejection fraction benefit from cardiac resynchronization therapy (CRT) and implantable cardioverter defibrillator (ICD). However, increasing numbers of patient with CRT and ICD devices produce overload of cardiology centers where patients are admitted to ambulatory visits. This study aims to find multivariate model predicting the requirement for ambulatory follow-up of cardiac implantable electronic devices (CIEDs).The LUCY study is an observational, cohort, prospective, 2-stage trial. As equal number of patients (300) will be included in the first and the second part of the study, finally, 600 patients will be included in the study. The inclusion criteria will be: age between 18 and 90 years, CHF (New York Heart Association classes I-III) and implanted ICD or CRT at least 30 days before study inclusion. The exclusion criteria will be dementia and other conditions impeding cooperation during the study. All patients included in the study will undergo standard ambulatory visit. Primary endpoint will be defined as any ambulatory visit qualified as necessary due to patient's condition or device malfunction diagnose by the cardiologist: any change in pharmacotherapy related to patient's clinical status assessed during the visit, any change in tachyarrythmia counter or discriminator status, any change in tachyarrythmia threshold, presence of ventricular undersensing or oversensing, presence of atrial or ventricular ineffective pacing, or device's pocket infection. Secondary endpoint will be defined as any ambulatory visit qualified as necessary due to the alarm identified via Medtronic CareLink Express (MCLE): sustained or treated ventricular tachyarrythmia, any not previously diagnosed supraventricular tachyarrythmia, or elective replacement indicator.Our study is the first attempt of implementation of the machine learning and elements artificial intelligence in health care optimization of patients with CIED. The LUCY will be an open product, available for additional testing and improvement with supplementary functionalities: quality of life assessment, teleconsultation, video-streaming, automated imagine recognizing. PMID- 30278558 TI - Anterolateral approach for lateral humeral condylar fractures in children: Clinical results. AB - To evaluate the clinical outcomes of an anterolateral approach for lateral humeral condylar fractures in children. The patients aged < 15 years undergoing surgery with an anterolateral approach for humeral lateral condylar fractures between April 2005 and March 2014 were investigated. Medical records and radiographs from 15 patients were reviewed. Average patient age at surgery was 6.0 years (range, 3-10 years). Based on Jakob's classification, 12 patients had type II fractures, and 3 patients had type III fractures. Based on Milch classification, 1 elbow was type I, and 14 elbows were type II. The average postoperative follow-up duration was 16.4 months (range, 6-58 months). Postoperative complications, and radiographic and clinical findings, including range of motion and Flynn criteria were evaluated. To evaluate humeral deformity, Baumann angle (BA) and the carrying angle (CA) were calculated on anteroposterior radiographs. There were no postoperative complications, including secondary displacement, deep infection, nonunion, avascular necrosis, or cubitus varus or valgus deformity. In the injured elbow, follow-up radiographs revealed an average BA of 69.1 degrees (range, 57-84 degrees ), versus 70.9 degrees (range, 61-83 degrees ) on the contralateral side. The average CA on the injured side was 10.3 degrees (range, 4-20 degrees ) versus 12.3 degrees (range, 6-24 degrees ) on the contralateral side. BA gain and CA loss (affected- compared with contralateral sides) averaged -1.4 degrees (range, -17 degrees to 9 degrees ) and 2.3 degrees (range, -2 degrees to 6 degrees ), respectively. The mean range of motion in the affected elbow averaged 4.7 degrees (range, 0-15 degrees ) in extension and 139.7 degrees (range, 135-140 degrees ) in flexion. Over 5 degrees loss of range of motion in the affected elbow compared with the contralateral side was not observed. However, 2 patients experienced over 5 degrees loss of CA in the affected elbow versus the contralateral side. Based on Flynn criteria, clinical results for both cosmetics and function were excellent in 13 patients, and good in 2. The advantages of the anterolateral approach are combining an optimal view of the anterior articular surface of the trochlea and capitellum and a limited risk of devascularization injury. We strongly recommend an anterolateral approach for these fractures in children to prevent postoperative deformity and to achieve anatomical reduction and reliable fixation. PMID- 30278556 TI - Comparison of periprosthetic bone remodeling after implantation of anatomic and tapered cementless femoral stems in total hip arthroplasty: A prospective cohort study protocol. AB - INTRODUCTION: Current total hip arthroplasty (THA) implant usage trends favor cementless fixation, and plenty studies have demonstrated that numbers of cementless femoral stems are associated with excellent long-term survivorship and functional outcomes. Various types of cementless femoral stems have been developed and utilized in multiple applications, including straight, tapered, anatomic, customized, short, and even neck stems. All of these designs aimed to achieve maximal primary stability and promote osseointegration. Nevertheless, stress-shielding and periprosthetic bone loss continue to occur and remain critical issues in promoting long-term survivorship of THA. Considering anatomic and tapered stems are the most popular cementless designs today, this prospective cohort study aimed to investigate the effect of stem design on stress-shielding and periprosthetic bone remodeling after implantation of an anatomic stem with proximal fixation (Ribbed Hip system; Waldemar Link, Hamburg, Germany) and the direct comparison to a fully coated tapered stem (LCU Hip system; Waldemar Link). MATERIALS AND METHODS: This prospective cohort study will comprise patients who receive primary unilateral THA with the Ribbed anatomic hydroxyapatite (HA) coated stem or LCU tapered fully HA-coated stem. The changes in periprosthetic bone mineral density after insertion of Ribbed and LCU stem prostheses will be assessed by means of dual-energy X-ray absorptiometry in the periprosthetic region of interest according to Gruen and colleagues. Standard anteroposterior and lateral plain radiography will be performed for qualitative assessment of the periprosthetic bone remodeling. The following items will be analyzed or measured on follow-up radiographs to compare with the initial appearance on the radiographs taken immediately postoperatively: cortical thickness in each Gruen zone, fitness of the distal stem within the isthmus, femoral stem alignment, radiolucent line, reactive line, periosteal bone reactions, and subsidence. Biologic fixation and stability of the cementless implant will be evaluated using Engh grading scale, and heterotopic ossification will be graded according to Brooker classification. Furthermore, Harris hip score and Western Ontario and McMaster Universities Osteoarthritis Index Score will also be assessed for postoperative functional evaluation. These radiologic and clinical assessments will be taken postoperatively, at 6 months, 1, 2, 3, 4, and 5 years after surgery. ETHICS AND DISSEMINATION: This study was approved by The First Affiliated Hospital of Chongqing Medical University Ethics Committee. The study results will be disseminated at national and international conferences and published in peer-reviewed journals.

PMID- 30278557 TI - Sonographic diagnosis of colorectal polyps in children: Diagnostic accuracy and multi-factor combination evaluation. AB - This study was established to evaluate the diagnostic value of ultrasonography in screening colorectal polyps in children and to discuss the necessity of colonic preparation before an ultrasonic examination.In this study, 288 children with colorectal polyps managed at our hospital between January 2007 and December 2016 were retrospectively reviewed. All patients were examined before and after basic colon preparation. The colorectal polyps were confirmed by colonoscopy/laparotomy and histopathology. Among all 288 patients, solitary polyps were identified in 278 patients (96.52%), and multiple polyps were identified in 10 patients (43 polyps) (3.48%) by colonoscopy/laparotomy and histopathology.By ultrasonic examination, 264 cases (264/278) were detected as solitary polyp and 9 cases (9/10) as multiple polyps (31 polyps). In 278 solitary polyps, 180 (64.74%) were detected by ultrasonic examination without a colon preparation. Following glycerine enema (10-20 mL) treatment, 264 (94.96%) cases were detected by ultrasonic examination. The sensitivity and specificity of ultrasonography with glycerine enema for the detection of colorectal polyps were 94.96% and 100%, respectively. Colon preparation significantly increased the proportion of polyps identified by ultrasonography (P < .0001), as well as the diagnostic rate of polyps in rectum, sigmoid colon and descending colon (P < .05).Ultrasonography can be the primary diagnostic method for screening colorectal polyps in children on the strength of its safety, validity, and accuracy. Basic colon preparation with glycerine enema is recommended for children, which enable the detection of intraluminal lesions before ultrasonic examination. PMID- 30278559 TI - A broad ligament solitary fibrous tumor with Doege-Potter syndrome. AB - INTRODUCTION: Solitary fibrous tumors (SFTs) are uncommon mesenchymal neoplasms and are particularly rare in the female genital tract. Doege-Potter syndrome is a paraneoplastic syndrome involving SFT-associated hypoglycemia. We report, for the first time, on a broad ligament SFT with Doege-Potter syndrome; additionally, we review 30 cases of women with SFTs reported in the literature. PATIENT CONCERNS: A 37-year-old woman who presented with life-threatening hypoglycemia and a pelvic mass (16 * 15 * 15 cm). DIAGNOSES: The patient was diagnosed with broad ligament SFT with Doege-Potter syndrome. INTERVENTIONS: Tumor resection, sub-extensive hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy were performed, and 6 cycles of adjuvant chemotherapy were administered. OUTCOMES: Serum glucose levels returned to normal as soon as the tumor was resected. Forty 3 months after operation, there was recurrence in the posterior peritoneal tissues. She underwent tumor resection and has remained tumor-free 28 months after this excision. CONCLUSION: Even though it is extremely rare, SFT should be quickly identified to prevent undue treatment delay and avoid unnecessary examination; surgery and long-term follow-up are recommended. SFT can be considered a highly invasive cancer, and intraoperative bleeding may occur. Although no correlation between adjuvant therapy and improved prognosis was found, further studies are required because of the small number of cases reported to date. PMID- 30278560 TI - Replacement of dexmedetomidine loading with midazolam for sedation in elderly patients with spinal anesthesia. AB - BACKGROUND: Dexmedetomidine is an effective sedative during spinal anesthesia. However, it requires a loading dose, which can result in transient hypertension, hypotension, bradycardia, and/or sinus arrest. In addition, the time required to reach an appropriate depth of sedation may cause anxiety to the patients. Therefore, we examined whether an intravenous bolus of midazolam could replace the loading dose of dexmedetomidine for sedation during surgery in elderly patients who received spinal anesthesia. METHODS: Patients aged over 60 years who scheduled to undergo total knee arthroplasty under spinal anesthesia were enrolled in this study. The patients were randomized into 2 groups. Patients in dexmedetomidine group (group D) (n = 20) were administered a loading dose of dexmedetomidine (1.0 MUg/kg over 10 min) intravenously followed by dexmedetomidine maintenance (0.5 MUg/kg/h). Patients in group MD (n = 20) were administered an intravenous midazolam (0.05 mg/kg) followed by dexmedetomidine maintenance (0.5 MUg/kg/h) intravenously. Heart rate (HR), mean arterial blood pressure (MBP), peripheral oxygen saturation (SpO2), and patient state index (PSI) were recorded. Ramsay sedation scale (RSS) scores were evaluated at 10 minutes after drug administration and the end of surgery. RESULTS: A total of 40 subjects were enrolled in the present study. At baseline, there was no between group difference in HR. Ten minutes after drug administration, group D had lower HR than group MD (62.1 +/- 9.4 versus 69.6 +/- 13.4, P = .047). PSI was significantly lower in group MD at 10 minutes after drug administration (82.8 +/- 13.0 versus 72.0 +/- 16.0, P = .024); there was no between-group difference at 30 and 60 minutes, and lower values in group D at the end of surgery (70.2 +/- 22.6 versus 79.7 +/- 10.9, P = .011). The RSS score showed statistically significantly deeper sedation in group MD 10 minutes after drug administration, but no difference at the end of surgery. CONCLUSIONS: An intravenous bolus of midazolam is a viable alternative to dexmedetomidine loading for sedation during surgery in elderly patients who received spinal anesthesia. This is especially effective for patients who are at high risk for bradycardia or who want a faster sedation. PMID- 30278561 TI - Polymorphism of R353Q (rs6046) in factor VII and the risk of myocardial infarction: A systematic review and meta-analysis. AB - OBJECTIVE: Genetic components substantially contribute to the development of myocardial infarction (MI), and R353Q polymorphism (rs6046) in FVII gene has been suspected to be associated with the risk of MI. METHODS: A meta-analysis was conducted on the links between R353Q polymorphism and the susceptibility of MI. A comprehensive literature search was performed on 8 electronic databases. The main effects of the genotypes were estimated using a logistic regression approach. The odds ratios with 95% confidence intervals were calculated using the conventional summary method meta-analysis. The possible sources of heterogeneity among the included studies were explored using meta-regression analysis and subgroup analysis. RESULTS: A total of 18 eligible case-control studies, comprising of 4701 cases and 5329 controls, were included. No overall statistical relationship was identified between R353Q and MI by any of the genetic models. The meta regression demonstrated that the Asian population, body mass index (BMI) category, and diabetes affected the heterogeneity. In addition, subgroup analyses showed that heterogeneities were identified in Asian population and BMI category, which highly agree with the results of meta-regression. CONCLUSIONS: The current meta-analysis suggested that R353Q polymorphism was not associated with the MI risk. Asian population, BMI category, and diabetes might be related to the incidence of MI. However, large-scale, case-control studies with rigorous designs are essential to provide accurate evidence. PMID- 30278562 TI - Importance of effusion of blood under the dura mater in forensic medicine: A STROBE - compliant retrospective study. AB - Subdural hemorrhage is commonly associated with mechanical brain injury and has a correspondingly high mortality rate. Subdural hematomas may immediately provoke symptoms or may be initially asymptomatic, with further symptoms evolving rapidly and fatally.The data regarding forensic autopsy of victims were obtained from The State Forensic Medicine Service of Lithuania between the years 2013 and 2016. A retrospective study was performed including 110 patients, whose cause of death was subdural hemorrhage. 95% confidence intervals were calculated.It was calculated, that in cases of sudden death, after subdural hemorrhage was diagnosed, a higher concentration of ethyl alcohol in blood (mean 2.22 +/- 1.3%) demanded a smaller amount of blood under the dura matter (mean 81.6 +/- 60.5 g) in order for the patient to die. It was also noted that hospitalized patients with subdural hemorrhage had a smaller concentration of blood ethyl alcohol (mean 1.33 +/- 1%) and a larger amount of blood under the dura (mean 135.6 +/- 82.9 g).Due to the toxic effect of ethyl alcohol, even a small amount (81.6 +/- 60.5 g) of blood under the dura matter can determine a sudden death. PMID- 30278563 TI - Comparison of urine neutrophil gelatinase-associated lipocalin and interleukin-18 in prediction of acute kidney injury in adults. AB - BACKGROUND: Neutrophil gelatinase-associated lipocalin (NGAL) and interleukin-18 (IL-18) were considered as the most promising biomarkers in prediction of acute kidney injury (AKI), but the priority of them remains unclear. METHODS: Databases of PubMed, Elsevier, Cochrane library, and Web of science were searched until August 23, 2017 for studies investigated the diagnostic value of urine NGAL (uNGAL) and urine IL-18 (uIL-18) for AKI in adults. Statistical analysis and investigation of heterogeneity source were using RevMan5.3, MetaDiSc1.40, and Stata14.0. RESULTS: A total of 7 studies were included involving 2315 patients from 7 countries in this article, of whom 443 (19.1%) developed AKI. The present meta-analysis demonstrated that uNGAL was more valuable compare with uIL-18 with effect size of 1.09 (95% CI 1.03-1.15, P = .004) in specificity, but not in sensitivity with effect size of 1.12 (95% CI 0.98-1.29, P = .104). Subgroup analysis presented that research design may be a foundation affecting the diagnostic accuracy of uNGAL and uIL-18 for AKI. No substantial publication bias was found. CONCLUSIONS: uNGAL is more specific for prediction of AKI in adults as compared with uIL-18. PMID- 30278564 TI - Vonoprazan versus proton pump inhibitors for the management of gastroesophageal reflux disease: A protocol for a systematic review with meta-analysis. AB - BACKGROUND AND AIM: Vonoprazan, a novel potassium-competitive acid blocking agent, is used in the management of gastroesophageal reflux disease (GERD). We aim to perform a systematic review and meta-analysis for the comparison of the effects of vonoprazan and proton pump inhibitors (PPIs) in GERD in randomized controlled trials (RCTs). METHODS: A systematic and comprehensive search will be performed using MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), Google Scholar, and clinical trial registries, for studies published up to September 2018. Only randomized clinical trials will be included. Primary outcomes of symptoms and esophageal erosion improvement in the intention-to-treat analysis, and secondary outcomes of symptoms and esophageal erosion improvement rate in the per protocol analysis, the comparative efficacy in terms of healing rate of esophageal erosion on endoscopy, the comparative efficacy in terms of improvement of esophageal impedance-pH study, adverse events, long-term safety, and the comparative efficacy in terms of CYP2C19 metabolite levels will be studied. The quality of included studies will be assessed using the modified risk of bias tool. Heterogeneity of estimates across studies as well as publication bias will be assessed. This systematic review and meta-analysis will be performed according to the protocol recommended by the Cochrane Collaboration and reported according to the preferred reporting items for systematic reviews and meta analysis (PRISMA) guidelines. All statistical analyses will be conducted using Stata SE version 15.0. RESULTS: The results of this systematic review and meta analysis will be published in a peer-reviewed journal. CONCLUSION: To our knowledge, this systematic review and meta-analysis will be the first to evaluate existing research comparing Vonoprazan and PPIs in GERD. Our study will provide information about the effect of vonoprazan and PPIs in GERD in RCTs. The review will benefit patients, healthcare providers, and policymakers. PMID- 30278565 TI - Knowledge of HIV status and antiretroviral therapy use among sexually transmitted infections service attendees and the case for improving the integration of services in South Africa: A cross sectional study. AB - We describe knowledge of human immunodeficiency virus (HIV) status, correct report of HIV status and antiretroviral therapy (ART) use among sexually transmitted infection (STI) service attendees in South Africa.An anonymous questionnaire was administered and serological HIV testing done. Proportions of attendees reporting knowledge of HIV status and HIV status consistent with laboratory results and ART use (among HIV positives) were determined as were factors associated with knowledge and inconsistent report of HIV status.Of 1054 attendees, 288 (27.3%) were HIV positive and 830 (78.8%) self-reported knowledge of HIV status. Not knowing one's HIV status was associated with male gender [adjusted Odds Ratio (aOR) 2.66 (95% confidence interval (CI) 1.70-4.18] medical circumcision [aOR 0.48 (95% CI 0.24-0.95)] and site [Gauteng Province (GP)-aOR 6.20 (95% CI 3.51-10.95), Eastern Cape (EC)-aOR 17.29 (95% CI 10.08- 29.66) versus Free State (FS)/Western Cape (WC) sites]. Of 219 HIV positive attendees with knowledge of HIV status, 136 (62.1%) self-reported being HIV positive, of whom 80 (58.8%) reported taking ARVs in the preceding 3 days. Inconsistent report of status was associated with males [aOR 2.26 (95%CI 1.05-4.87)], prior STI treatment [aOR 0.33 (95% CI 0.16-0.69)], recent HIV testing (6months) [aOR 3.20 (95% CI 1.62-6.36)] and site [GP-aOR 6.89 (95% 3.21-14.82), EC-aOR 5.08 (95% CI 2.15-11.64) versus FS/WC sites]. Knowledge of HIV status was lower than targeted. HIV testing and linkage to care services are essential in STI-related care and validation of self-reported indicators in this population maybe necessary. PMID- 30278566 TI - Effect of Montmorillonite powder on intestinal mucosal barrier in children with abdominal Henoch-Schonlein purpura: A randomized controlled study. AB - BACKGROUND: Our previous studies found that intestinal barrier function has been changed in children with abdominal Henoch-Schonlein purpura (HSP). Montmorillonite has been shown to be protective for digestive tract mucosa. OBJECTIVE: The present study aimed to investigate whether Montmorillonite powder could improve the intestinal mucosal barrier function in children with abdominal HSP. METHODS: Using a randomized controlled study design, we compared plasma levels of diamine oxidase (DAO), D-lactate, and endotoxin in children with abdominal HSP before and after Montmorillonite powder treatment. RESULTS: Among 28 patients in experimental group and 30 in control group, there was no significant difference in age, sex, height, weight, and course of disease between 2 groups (P > .05). Before treatment, there was no statistical difference in DAO, D-lactic acid, and endotoxin between experimental group and the control group (P > .05). However, significant differences were detected for DAO and D-lactate after treatment in comparison to before treatment in the Montmorillonite experimental group (P < .05). Such differences were not found in the control group (P > .05). CONCLUSION: Montmorillonite powder is effective in the treatment of HSP via maintaining intestinal mucosal barrier function. PMID- 30278567 TI - Apelin: A novel prognostic predictor for atrial fibrillation recurrence after pulmonary vein isolation. AB - Apelin, the ligand for the APJ receptor, is involved in the pathogenesis of atrial fibrillation (AF). However, whether serum apelin can predict the recurrence of AF after pulmonary vein isolation (PVI) has not been determined.A prospective cohort study was performed in patients with AF (but without structural heart disease) who were undergoing first-time PVI. Serum apelin-12 was measured by enzyme-linked immunosorbent assay. Echocardiographic examination was performed at baseline, 3 months, and 6 months after PVI. Patients were followed up for 6 months after PVI, and the association between baseline apelin-12 and AF recurrence (early recurrence: within 3 months after ablation; late recurrence: 3 6 months after ablation) was analyzed.A total of 61 patients were included in the study. Baseline serum level of apelin-12 was significant lower in patients with early (median [interquartile range]: 1844 [1607-2061] vs 2197 [1895-2455] ng/L, P = .01) and late (1639 [1524-1853] vs 1923 [1741-2303] ng/L, P = .02) AF recurrence compared with patients without these events. Results of Cox stepwise multivariate analysis demonstrated that lower baseline apelin-12 (<2265 ng/L) was independently associated with increased AF recurrence within 6 months after PVI (P < .05). The specificity and positive predictive value of apelin-12 for AF recurrence were significantly higher than those of baseline N-terminal brain proBNP (60.4% vs 28.6%, P < .001; 58.8% vs 34.4%, P = .01), although the sensitivity and negative predictive value were similar.Reduced baseline serum apelin-12 may be an independent risk factor for the recurrence of AF after PVI in patients without structural heart disease. PMID- 30278568 TI - The use of 5% lidocaine medicated plaster for acute postoperative pain after gynecological surgery: A pilot randomized controlled feasibility trial. AB - OBJECTIVES: To examine the feasibility and potential efficacy of 5% lidocaine medicated plaster for acute postoperative pain in a parallel, blinded, randomized controlled pilot trial. METHODS: Twenty-eight women undergoing elective gynecological surgery with midline incisions were randomly allocated 5% lidocaine medicated patch (Lignopad) or placebo plasters. Postoperative pain at rest and on movement at 24 hours were the primary study endpoints, with secondary endpoints of postoperative pain within the first 48 hours, cumulative morphine consumption (mg), predicted peak flow rate (PFR) (%) and adverse effects. We assessed pain scores at rest and on movement using the visual analogue scale (0-100). RESULTS: The lidocaine patch group had lower postoperative pain scores at rest at 24 hours (mean difference [MD] -15.1, 95% confidence interval [95% CI] -28.3 to -2.0; P = .024) but not on movement at 24 hours (MD -6.4, 95% CI -22.7 to 9.9; P = .445). Compared to placebo, lidocaine may slightly lower cumulative morphine consumption (mg) over time (MD -3.4, 95% CI -6.9 to 0.2; group*time interaction P = .065). The difference in improvement in the PFR over time after surgery between groups appeared small (group*time P = .0980). No adverse effects occurred. CONCLUSIONS: Lidocaine patch may provide a clinically important reduction in postoperative pain intensity. A larger trial to confirm the efficacy and safety of lidocaine patch is feasible after modifying the inclusion criteria and collecting patient centered outcomes, such as quality of recovery and patient satisfaction. PMID- 30278569 TI - A double blind randomized placebo controlled pilot study of single-dose preoperative modafinil for functional recovery after general anesthesia in patients with obstructive sleep apnea. AB - BACKGROUND: We theorized that modafinil, an atypical psychomotor stimulant, utilized to improve daytime somnolence in patients with obstructive sleep apnea, would improve functional recovery after general anesthesia by improving time to extubation, post-anesthesia care unit (PACU) length of stay and subjective recovery after general anesthesia. METHODS: A double blind, randomized, placebo controlled pilot study was performed. 102 patients with the diagnosis of obstructive sleep apnea (OSA) were randomized to receive either 200 mg of modafinil or placebo before general anesthesia. The trial was terminated for futility. The primary outcome was PACU length of stay between groups. Secondary functional metrics of improved post-anesthesia recovery were compared between groups. RESULTS: No difference between groups was found on the primary outcome of PACU length of stay (PACULOS). Emergence from general anesthesia was not significantly different when assessed by the time period between termination of volatile anesthetic and extubation. Similarly, no difference between groups was found in intraoperative bispectral index (BIS) values, postoperative pain scores or narcotic consumption (morphine equivalent units). In the post-anesthesia care unit, respiratory rate was increased and mean arterial pressure was lower in the modafinil group. CONCLUSIONS: Our results suggest that the use of single-dose preoperative modafinil may not improve functional recovery after general anesthesia in patients with the diagnosis of OSA. Further research is needed before use of atypical psychomotor stimulants in this surgical population. PMID- 30278570 TI - Triglyceride to HDL-cholesterol ratio as an independent risk factor for the poor development of coronary collateral circulation in elderly patients with ST segment elevation myocardial infarction and acute total occlusion. AB - To determine the prognostic role of triglyceride (TG) to high-density lipoprotein cholesterol (HDL) ratio for poorly developed coronary collateral circulation (CCC) in elderly patients with ST-segment elevation myocardial infarction (STEMI) and acute total occlusion (ATO).As a retrospective case-control study, elderly patients (age >=60 years) with both STEMI and ATO (n = 346) were classified as having either poorly- or well-developed CCC (Rentrop grades 0-1 and 2-3, respectively). The ratio of TG/HDL was calculated according to the detected levels of TG and HDL. The difference of TG/HDL ratio in those 2 groups was compared by Student t test, and multivariate logistic regression analysis indicating occurrence of poorly developed CCC was performed. Receiver operator characteristic curve (ROC) analysis of TG/HDL ratio which determine the optimal cut-off value of TG/HDL ratio was applied.The TG/HDL ratio was significantly higher in patients with poorly developed CCC than in those with well-developed CCC (2.88 +/- 2.52 vs 1.81 +/- 1.18, P < .001). In multivariate logistic regression analysis, higher TG/HDL ratio (OR 1.789, 95% CI 1 . 346-2.378, P < .001) and the presence of left circumflex branch of coronary artery (LCX) occlusion (OR6.235, 95% CI 2.220-17.510, P = .001) were emerged as independent positive predictors of poor development of CCC, whereas presence of right coronary artery (RCA) occlusion (OR 0.474, 95% CI 0.265-0.850, P = .002) and onset time (OR 0.693, 95% CI 0.620-0.775, P < .001) were found as negative indicators. The optimal cut-off value of TG/HDL ratio was found as 1.58 in ROC analysis, which yielded an area under the curve value of 0.716 (95% CI 0.654 0.778, P < .001) and demonstrated a sensitivity of 80.9% and a specificity of 59.3% for prediction of poorly developed CCC.TG/HDL ratio is an independent risk factor for predicting poor development of CCC in elderly patients with STEMI and ATO. PMID- 30278571 TI - The role of third-line chemotherapy in recurrent or metastatic gastric cancer: A cohort study with propensity score matching analysis. AB - In recurrent or metastatic gastric cancer, second-line chemotherapy is generally recommended in current guidelines. Although third-line therapy is often performed in daily practice in some countries, there are only a few reports about its benefits.A retrospective review was conducted on 682 patients who underwent at least first-line chemotherapy for recurrent (n = 297) or primary metastatic (n = 385) disease. Clinicopathological characteristics and overall survival (OS) were analyzed according to lines of chemotherapy.One hundred sixty-seven patients (24.5%) underwent third- or further-line therapy. Third- or further-line therapy was frequently performed in patients with young age (<70) (P < .0001), Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1 (P < .0001), surgical resection before first-line therapy (P = .007), and first-line combination regimen (P = .001). The median OS for all patients after the initiation of first-line therapy was 10 months. The median OS of patients who received third- or further-line therapy was significantly longer than that of patients who received second- or lesser-line therapy (18 vs 8 months, P < .0001). The multivariate analysis revealed that third- or further-line therapy was independently associated with favorable OS (hazard ratio = 0.58, P < .0001). Moreover, patients who received third- or further-line therapy demonstrated better OS both in univariate (P = .002) and multivariate (P < .0001) analysis even after propensity score matching using baseline characteristics. The median OS after the start of third-line chemotherapy was 6 months. In addition, ECOG PS 0 or 1 at the initiation of third-line therapy (P < .0001) and surgical resection (P = .009) were independently associated with longer OS after third-line therapy.The current study suggests that third-line therapy could be recommended for recurrent or metastatic gastric cancer patients with good PS after progression from second-line chemotherapy in clinical practice. PMID- 30278572 TI - Chinese herbal medicine for opioid induced constipation in cancer patients: Protocol for a systematic review. AB - BACKGROUND: Opioid induced constipation (OIC) is a symptom that is commonly encountered in cancer pain management. Chinese herbal medicine (CHM) has been widely used to improve OIC in China. Many clinical trials indicate that CHM could improve OIC. In this systematic review, we aim to evaluate the effectiveness and safety of CHM for OIC in cancer patients. METHODS: We will search the following electronic databases for randomized controlled trials to evaluate the effectiveness and safety of CHM for OIC in cancer patients: CENTRAL, EMBASE, MEDILINE, CINAHL and China National Knowledge Infrastructure. Each database will be searched from inception to June 2018. The entire process will include study selection, data extraction, risk of bias assessment and meta-analyses. RESULTS: This proposed study will evaluate the effectiveness and safety of CHM for OIC. The outcomes will include change in bowel movements, quality of life and adverse events. CONCLUSIONS: This proposed systematic review will evaluate the existing evidence on the effectiveness and safety of CHM for OIC in cancer patients. DISSEMINATION AND ETHICS: The results of this review will be disseminated through peer-reviewed publication. Because all of the data used in this systematic review and meta-analysis has been published, this review does not require ethical approval. Furthermore, all data will be analyzed anonymously during the review process. PMID- 30278573 TI - Clinical and cost-effectiveness of collaborative traditional Korean and Western medicine treatment for low back pain: A protocol for a prospective observational exploratory study. AB - BACKGROUND: In South Korea, a few patients with low back pain (LBP) are currently being treated with a combination of traditional Korean medicine (KM) and Western medicine (WM). Although a recent research has reported results regarding patient satisfaction and exploratory effectiveness, evidence of comparative effectiveness still needs to be reviewed. The aim of this study is to evaluate the clinical and cost-effectiveness of KM and WM collaborative treatment (CT) compared with that of sole treatment (ST) for patients with LBP in Korea. METHOD/DESIGN: This multisite, prospective observational comparative effectiveness research study is part of a nationwide pilot project for KM and WM collaboration launched by the Korean Ministry of Health and Welfare. The duration of the study is 8 weeks, and the target number of inclusion is 360 patients. Participants receive treatment according to their treatment plan, and a researcher conducts investigations thrice, every 4 weeks. In the final analysis, the merged data from the participants' questionnaire responses, hospital medical records, and administrative data, and Health Insurance Review and Assessment service data will be compared between the CT and ST groups. DISCUSSION: This study will provide clinical and economic information about CT for LBP, which might be a milestone for establishing future polices about this collaboration in Korea. TRIAL REGISTRATION: The study protocol has been registered with the Clinical Research Information Service (KCT0002827). PMID- 30278574 TI - Problems to affect long-term survival for breast cancer patients: An observational study of subsequent lung/bronchus malignancies. AB - The overall survival of breast cancer (BC) patients increased significantly for decades; however, their long-term survival was seriously impaired by subsequent malignancies. This study aimed to investigate the risk factors of subsequent lung / bronchus primary malignancies among BC survivors.A total of 535,941 BC female survivors diagnosed were identified by using SEERStat database in 1973 to 2014. Among them, 9398 had subsequent lung/bronchus malignancies. Clinico-pathological risk factors were evaluated for the development of subsequent lung/bronchus cancer. The main measures were the incidence and risk factors of subsequent lung/bronchus primaries. Logistic regression analysis and survival analysis were performed.Overall, among 535,941 BC survivors, 73,394 (13.69%) patients with subsequent primaries were identified from 1973 to 2014. The overall medium second tumor-free time was 72 months. Estrogen receptor (ER)-positive, progesterone receptor (PR)-positive, human epidermal growth factor receptor-2 (HER2)-positive, radiotherapy, and surgery treatment were protective factors against overall subsequent malignancies, whereas HER2/hormone receptor (HR) subtype triple negative, increasing tumor size, low differentiation grade, and high TNM stage were risk factors associated with overall subsequent malignancies. Surgical implantation reconstruction was risk factor for lung/bronchus cancer. Even though BC patients had a favorite 5-year survival, their long-term survival was affected by subsequent malignancies, especially for lung/bronchus cancer with high mortality.Nearly 13% BC survivors suffered from subsequent malignancies. Increased risk was related to HER2/HR triple negative and advanced TNM stages. Radiotherapy and surgery were protective factors. Our findings may inform the subsequent cancer counseling of female BC survivors. PMID- 30278575 TI - Associations of race, mechanism of injury, and neighborhood poverty with in hospital mortality from trauma: A population-based study in the Detroit metropolitan area. AB - Health disparities based on race and socioeconomic status are a serious problem in the US health care system, but disparities in outcomes related to traumatic injury have received relatively little attention in the research literature.This study uses data from the State Inpatient Database for Michigan including all trauma-related hospital admissions in the period from 2006 to 2014 in the Detroit metropolitan area (N = 407,553) to examine the relationship between race (White N = 232,109; African American N = 86,356, Hispanic N = 2709, Other N = 10,623), socioeconomic background, and in-hospital trauma mortality.Compared with other groups, there was a higher risk of mortality after trauma among African Americans (odds ratio [OR] = 1.20, P < .001), people living in high-poverty neighborhoods (OR = 1.01, P < .001), and those enrolled in public health insurance programs (OR = 1.53, P < .001). African American patients were more likely to have had traumatic injuries caused by certain mechanisms with higher risk of death (P < .001). After controlling for mechanism alone in multiple logistic regression, African American race remained a significant predictor of mortality risk (OR = 1.12, P < .001). After additionally controlling for the socioeconomic factors of insurance status and neighborhood poverty levels, there were no longer any significant differences between racial groups in terms of mortality (OR = 0.99, P = .746).These results suggest that in this population the racial inequalities in mortality outcomes were fully mediated by differences between groups in the pattern of injuries suffered and differences in risk based on socioeconomic factors. PMID- 30278576 TI - Association between polycystic ovarian syndrome and endometrial, ovarian, and breast cancer: A population-based cohort study in Taiwan. AB - Polycystic ovary syndrome (PCOS) is a common endocrine disorder among the women of reproductive age. We conducted a nationwide population-based retrospective cohort study to analyze the association between PCOS and the subsequent development of gynecological cancers, namely endometrial, breast, and ovarian cancer.For this population-based cohort study, we used the Taiwan National Health Insurance Research Database, which contains information on approximately 24.7 million insured individuals. The cohort included women who had received a diagnosis of PCOS between 1998 and 2013. An age-matched systematic random sampling method with a ratio of 1:4 was used for patient selection for the non PCOS reference cohort. Multivariate Cox proportional hazard regression analysis was used to determine the effects of PCOS on the risks of gynecologic and breast cancer. The data are presented as hazard ratios (HRs) with 95% confidence intervals (CIs).The PCOS cohort consisted of 8155 patients with PCOS, and the comparison cohort consisted of 32,620 matched patients without PCOS. The incidence of endometrial cancer was 226 and 15 per 100,000 person-years in the PCOS and comparison groups, respectively. A statistically significant higher risk of endometrial cancer was found in the PCOS cohort (adjusted HR [aHR] = 17.7, 95% CI = 4.9-64.2) than in the comparison cohort. However, no association was observed between PCOS and ovarian (aHR = 1.64, 95% CI: 0.63-4.27) or breast cancer (aHR = 0.98, 95% CI: 0.58-1.65).The results of this large population-based cohort study supported the premise that women with PCOS might have an increased risk of endometrial cancer, but no association between PCOS and the risks of ovarian and breast cancer was found. PMID- 30278577 TI - Can ultrasound be an assessment tool for sagittal spine mobility and chest expansion in patients with ankylosing spondylitis? AB - We aimed to examine whether ultrasound (US) is useful for evaluating spinal mobility and chest expansion in ankylosing spondylitis (AS) patients and determine a cutoff value to identify reduced sagittal lumbar mobility.Our cross sectional study included 50 AS patients and 50 controls. Metric measurements and Bath AS indices were measured in AS patients. The distance between C6-C7, T11 T12, and L4-L5 vertebrae was measured, and the difference and percentage of difference between erect position and maximal cervical and lumbar flexion was calculated (T11-T12dif, T11-T12%, L4-L5dif, L4-L5%, T+L dif, T+L%). Intercostal divergence was measured 1.5 cm away on the left from the sternocostal space during maximum inhalation and maximum exhalation, and the difference and percentage of difference between them was calculated (ICdif, IC%).All metric measurements were lower in the AS group except for tragus-to-wall distance. T11 T12dif, T11-T12%, L4-L5dif, T+L dif, and T+L% values were higher in the control group, while other US measurements did not differ between the groups. All US measurements except ICdif and IC% correlated with the Bath AS Metrology Index.Thus, US may be used for assessing spinal mobility in patients with AS. T11 T12dif <0.79 cm may show decreased lumbar sagittal mobility. PMID- 30278578 TI - The clinical application value of the plasma copeptin level in the assessment of heart failure with reduced left ventricular ejection fraction: A cross-sectional study. AB - This study aimed to evaluate the clinical applicability of the plasma copeptin level to assess heart failure with reduced left ventricular ejection fraction (HFrEF).One hundred thirty-one patients with HFrEF, 127 patients with heart failure with preserved left ventricular ejection fraction (HFpEF), and 119 healthy candidates were involved. The basic data and examination results of patients were collected. The heart function of the patients with HFrEF and HFpEF were graded on the basis of the criteria of New York Heart Association (NYHA) classification. The plasma copeptin and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels were tested using enzyme-linked immunosorbent assays (ELISAs).The copeptin and NT-proBNP levels were higher in the HFrEF group than in the HFpEF group. The copeptin and NT-proBNP values increased as the NYHA grade increased in the patients with HFrEF. However, for the patients with HFpEF, the copeptin levels did not change markedly as the NYHA grade increased. The copeptin levels were positively correlated with the NT-proBNP levels in the patients with HFrEF; however, there was no correlation between the copeptin and NT-proBNP values in the patients with HFpEF.Copeptin is involved in the process of progression in patients with HFrEF and the copeptin values might be useful for HFrEF prediction and assessment in the clinic. PMID- 30278579 TI - Raman characterizations of red blood cells with beta-thalassemia using laser tweezers Raman spectroscopy. AB - This study aimed to study the differences in Raman spectra of red blood cells (RBCs) among patients with beta-thalassemia and controls using laser tweezers Raman spectroscopy (LTRS) system.A total of 33 patients with beta-thalassemia major, 49 with beta-thalassemia minor, and 65 controls were studied. Raman spectra of RBCs for each sample were recorded. Principal component analysis (PCA), one-way analysis of variance (ANOVA), and independent-sample t test were performed.The intensities of Raman spectra of beta-thalassemia (major and minor) RBCs were lower than those of controls, especially at bands 1546, 1603, and 1619 cm. The intensity ratio of band 1546 cm to band 1448 cm demonstrated that there was a significant difference between the spectra of beta-thalassemia major (mostly below 2.15) and those of controls. The spectra of controls could be well distinguished from those of beta-thalassemia major using PCA. After normalization, the spectra of two different genotypes with beta/beta mutations mainly overlapped, while those with beta/beta mutations had lower intensity at bands 1546, 1603, and 1619 cm.The present study provided Raman characteristics of RBCs in patients with beta-thalassemia major and supported the use of LTRS as a method for screening beta-thalassemia major. The recognition rate for beta thalassemia minor needs to be further improved. PMID- 30278580 TI - Coinfection with cryptococcus and aspergillus in an immunocompetent adult: A case report. AB - RATIONALE: Aspergillus and Cryptococcus exposure can cause serious secondary infections in human lungs, especially in immunocompromised patients or in conjunction with a chronic disease caused by low disease resistance. Primary invasive fungal infections are clinically rare; therefore, coexistence of 2 fungi at an infection site is uncommon. This paper reports a case of healthy male who was diagnosed with both Cryptococcus neoformans and Aspergillus infections. PATIENT CONCERNS: A healthy 33-year-old male office worker was admitted to the Second Hospital of Jilin University for hemoptysis. A chest computed tomography (CT) scan showed a cavity, which was formed by the thick dorsal wall of the lower left lobe with an irregular inner wall and burr changes around the lesion. INTERVENTION: After 1.0 week of antibiotic and antituberculosis treatment, the hemoptysis symptoms remained. A resection of the left lower lobe was performed. DIAGNOSES: The postoperative pathological reports indicated the presence of both Aspergillus and Cryptococcus. The 2 fungal lesions were separate but within the same location. OUTCOMES: After treatment, the patient no longer had hemoptysis. LESSONS: The current study indicated that fungi can infect not only immunocompromised patients but also healthy people, and that there can be 2 separate fungal infections at the same infection site. PMID- 30278581 TI - Alveolar architectures preserved in cancer tissues may be potential pitfalls for diagnosis and histological subtyping of lung cancer: Three case reports. AB - RATIONALE: Lung cancer is a leading cause of cancer-related deaths globally. Appropriate histopathological diagnosis and subtyping form the basis and are critical for clinical therapies. PATIENT CONCERNS: Here, we report about 3 patients who had a nodule in the lung. Cancer cells grow in the alveolar cavity in many lung carcinomas. In all our 3 cases preserved alveolar architectures were found in tumor tissues which may lead to diagnostic pitfalls. DIAGNOSES: Three patients had tumors that were diagnosed as nonsmall cell lung cancers, including large-cell carcinoma, peripheral squamous cell carcinoma, and large-cell neuroendocrine carcinoma, all of which contained structures of preserved alveolar cells that could be mistaken as malignant glandular components. The preserved alveolar cells formed acinar or duct-like structures enwrapped in the lung cancer tissues or surrounded the nests of cancer cells. Proliferative alveolar cells adjacent to cancer tissues were observed, and papillary structures and marked atypia, both of which may be mistaken as part of adenocarcinoma or carcinoma with glandular differentiation, were also observed. INTERVENTIONS: All patients underwent surgery and postoperative chemotherapy. OUTCOMES: The patients had no recurrence at 5-, 8-, or 10-month follow-up after the last surgery. LESSONS: Preserved alveolar cells with different architectures may be observed in various lung cancer tissues and may be mistaken as adenocarcinoma or carcinoma with glandular differentiation. Distinct morphological and immunohistochemical features may help distinguish preserved alveolar cells from tumor components. PMID- 30278582 TI - Effects of neurofeedback versus methylphenidate for the treatment of attention deficit/hyperactivity disorder protocol for a systematic review and meta-analysis of head-to-head trials. AB - INTRODUCTION: Attention-deficit/hyperactivity disorder (ADHD) is developmental disorder characterized by inattention and/or hyperactivity/impulsivity. Psychostimulants, including methylphenidate (MPH), are recommended as a first line pharmacological intervention, whereas neurofeedback (NF) has been proposed as a nonpharmacological option. The comparative effects of MPH and NF need further exploration. We will conduct a systematic review and meta-analysis of head-to-head randomized controlled trials (RCTs) comparing the efficacy and/or tolerability of MPH and NF in children/adolescents and adults with ADHD. METHOD AND ANALYSIS: We will include published as well as unpublished data. Two investigators will independently search PubMed, OVID, ERIC, Web of Science, ClinialTrials.gov, and a set of Chinese databases, including CNKI, CQVIP, and WanFang for head-to-head RCTs comparing MPH and NF. Experts will be contacted for unpublished data. The primary outcome will be the efficacy on ADHD core symptoms, measured by the change in the severity of ADHD symptoms, from baseline to endpoint and, if available, at follow-up (at any available time point). Secondary outcomes will be: dropouts for any reasons; efficacy on neuropsychological measures (working memory, inattention, and inhibition). We will conduct subgroup analyses to assess the impact of the following variables: age; type of NF; language of publication; comorbidities. Additionally, we will carry out meta regression analyses to investigate the effect of sponsorship, year of publication, duration of intervention, and age of participants. Sensitivity analyses will be conducted to test the robustness of the findings. Risk of bias of individual studies will be assessed using the Cochrane risk of bias tool. Analyses will be performed using Comprehensive Meta-Analysis Software. ETHICS AND DISSEMINATION: No ethical issues are foreseen. Results from this study will be published in a peer-reviewed journal and presented at relevant national and international conferences. TRIALS REGISTRATION NUMBER: PROSPERO CRD42018090256.

PMID- 30278583 TI - Increased EXT1 gene copy number correlates with increased mRNA level predicts short disease-free survival in hepatocellular carcinoma without vascular invasion. AB - Exostosin-1 (EXT1) has been demonstrated to participate in the progression of many cancers. However, it has not been previously described in patients with hepatocellular carcinoma (HCC) without vascular invasion. In this study, we got the accurate data of EXT1 mRNA Z-score from the CBio data portal of The Cancer Genome Atlas (TCGA), which was used to express the level of EXT1 gene expression. We analyzed the EXT1 gene expression between HCC and normal liver tissue and compared the clinical significance of tumor tissue's EXT1 gene expression of HCC patients without vascular invasion based on data from TCGA database. The association between EXT1 gene expression and disease-free survival (DFS) was further analyzed. EXT1 gene copy number was also analyzed in this study. Univariate and multivariate analyses showed that high EXT1 gene expression group was significantly poorer than that of the low EXT1 gene expression group (P = .004). In addition, EXT1 gene expression was positively associated with alpha fetoprotein (AFP), which is a well-known marker for HCC. There was a significant positive correlation between EXT1 copy number and upregulated EXT1 gene (P < .0001). In conclusion, upregulation of EXT1 could be an important indicator to the short DFS of HCC patients without vascular invasion. EXT1 gene copy number amplification is one of the mechanisms underlying the upregulation of EXT1. PMID- 30278585 TI - Identification of key microRNAs and their targets in exosomes of pancreatic cancer using bioinformatics analysis. AB - Pancreatic cancer (PC) is one of the most lethal tumors, due to late diagnosis and limited surgical strategies. It has been reported that serum exosomal microRNAs (S-Exo-miRNAs) play a pivotal role as signaling molecules and serve as noninvasive diagnosis methods for PC. The combination of S-Exo-miRNAs with the corresponding target also plays an important role in the tumor microenvironment.Here we investigated S-Exo-miRNAs involved in PC. The gene expression profile was downloaded from the Gene Expression Omnibus (GEO) database. The analysis was carried out using GEO2R. The targets of differentially expressed serum exosomal miRNAs (DE-S-Exo-miRNAs) were predicted by 4 bioinformatic algorithms (miRanda, miRDB, miRWalk, and Targetscan). Further analysis with gene ontology (GO) and Kyoto Encyclopedia of Genomes pathway (KEGG) enrichment analyses were performed with Cytoscape software version 3.4.0. Subsequently, the interaction regulatory network of target genes was performed with the Search Tool for the Retrieval of Interacting Genes (STRING) database (http://www.string-db.org/) and visualized using Cytoscape software.We downloaded the gene expression profile GSE50632, which was based on an Agilent microarray GPL17660 platform containing 4 eligible samples. In total 467 DE-S-Exo-miRNAs were obtained, including 7 overexpressed miRNAs (1.50%), and 460 remaining underexpressed miRNAs (98.50%). The databases miRWalk, miRDB, miRanda, and TargetScan were used to predict their potential targets, which were subsequently submitted to Cytoscape software version 3.4.0 (www.cytoscape.org). Next the functional and pathway enrichment analysis were used for the KEGG pathway and GO categories analysis. The enrichment analysis identified the genes involved in such processes as developmental and negative regulation of multicellular organismal processes, regulation of anatomical structure morphogenesis, regulation of cell death, apoptotic processes and mitogen-activated protein kinase (MAPK) signaling pathway, transforming growth factor - beta (TGF -beta) signaling pathway, cyclic adenosine monophosphate (cAMP) signaling pathway, and the phosphatidylinositol-3 kinases/Akt (PI3K-Akt) signaling pathway. Subsequently according to the protein-protein interaction (PPI) network, the top 10 genes were obtained. The enrichment analyses of the genes involved in a significant module revealed that these genes were related to the TGF-beta signaling pathway. After reviewing the literature, we identified the apoptosis genes, and their corresponding miRNAs that have a relationship with apoptosis of the tumor.This analysis provides a comprehensive understanding of the roles of S-Exo-miRNAs and the related targets in the development of PC. Additionally, the present study provides promising candidate targets for early diagnosis and therapeutic intervention. However, these predictions require further experimental validation in future studies. PMID- 30278586 TI - Prognostic factors to survival of patients with chondroblastic osteosarcoma. AB - This study was aimed to reveal the changes in survival rates and prognostic factors to survival of chondroblastic osteosarcoma (COS).Patients from the Surveillance, Epidemiology, and End Results (SEER) database were retrieved. Kaplan-Meier survival analysis and Cox proportional hazard model were used during analysis.There were significant differences on overall survival between subtypes of osteosarcoma (P < .001*). Overall survival of COS did not change significantly during last forty years (P = .610), and cancer-specific survival increased to a plateau in 1980s and then remained stable (P = .058). Younger onset age, patients of white race, well and moderately differentiated tumors, and surgery independently predicted better overall (Hazard ratio [HR]: 1.034, P < .001*; HR: 0.538, P = .004*; HR: 0.240, P = .020* and HR: 0.350, P < .001*, respectively) and cancer-specific (HR: 1.031, P = .002*; HR: 0.592, P = .036*; HR: 0.098, P = .027* and HR: 0.253, P < .001*, respectively) survival. Metastasis at diagnosis independently predicted worse overall (HR: 3.108, P < .001*) and cancer-specific (HR: 4.26, P < .001*) survival compared to no metastasis.Younger onset age, white race, well and moderately differentiated tumors, no metastasis at diagnosis and surgical resection can independently predict better overall and cancer-specific survival of COS. PMID- 30278587 TI - Repeated cardiac arrest caused by an air embolism during hepatic resection: A case report. AB - RATIONALE: Although venous air embolism (VAE) during liver operation has been reported occasionally, fatal VAE in hepatic resection is uncommon. Prompt detection of VAE by transesophageal echocardiography (TEE) is crucial for effective therapy. We describe a case of fatal VAE that caused repeated cardiac arrest during hepatic resection and was confirmed by TEE. PATIENT CONCERNS: A 51 year-old woman with a body weight of 50 kg underwent partial liver resection due to intrahepatic duct calculus. She had a 1-year history of intrahepatic duct calculus without cardiopulmonary disease. The operation was performed under general anesthesia combined with epidural block. When the inferior vena cava was compressed, the PetCO2 level decreased abruptly from 30 to 10 mmHg, followed by a decrease in SpO2 and the development of hypotension. Her heart rate increased with ST interval elevation on electrocardiography monitoring. Ephedrine and phenylephrine were administered immediately but had little effect. Cardiac arrest occurred. DIAGNOSES: Air embolism was detected by TEE. INTERVENTIONS: Resuscitation was successful although cardiac arrest occurred repeatedly. OUTCOMES: The patient returned to consciousness 6 hours postoperatively but died of multiorgan dysfunction 10 days later. LESSONS: Fatal air embolism may happen during hepatic resection. Prompt detection of VAE by TEE is crucial for effective therapy and should always be available during hepatic resection. PMID- 30278588 TI - ANRIL polymorphism rs4977574 is associated with increased risk of coronary artery disease in Asian populations: A meta-analysis of 12,005 subjects. AB - BACKGROUND: Several studies have shown that ANRIL polymorphism may be associated with the risk of coronary artery disease (CAD). However, these studies do not provide a clear consensus in Asian population. Thus, this meta-analysis was aimed to evaluate the relationship between the common variant rs4977574 in ANRIL and CAD risk in Asian population. METHODS: We conducted a systematic literature search of PubMed, Embase and the Cochrane Library and 2 Chinese databases. A total of 12,005 subjects from 6 independent studies were included. The pooled odds ratio (OR) and their corresponding 95% confidence intervals (CIs) were used to assess the association between rs4977574 and CAD using random effects model. RESULTS: A significant association was observed between rs4977574 and CAD risk under the allelic (OR: 1.18, 95% CI: 1.04-1.34, P = .010), recessive (OR: 1.27, 95% CI: 1.01-1.60, P = .04), dominant (OR: 1.28, 95% CI: 1.13-1.44, P = .002), homozygous (OR: 1.46, 95% CI: 1.15-1.86, P = .002), and heterozygous model (OR: 1.17, 95% CI: 1.07-1.28, P = .0004), especially in the Chinese subgroup and the myocardial infarction (MI) subgroup (P < .05). CONCLUSION: The ANRIL polymorphism rs4977574 is associated with CAD risk in Asian population. The rs4977574 with G allele may confer to a higher risk of CAD, especially MI. PMID- 30278592 TI - The why of neurological reflexes. PMID- 30278591 TI - Combination of the ankle-brachial index and percentage of mean arterial pressure to improve diagnostic sensitivity for peripheral artery disease: An observational study. AB - The ankle-brachial index (ABI) is a noninvasive method for screening for peripheral artery disease (PAD). However, false-negative findings of the ABI may limit its clinical use. The percentage of mean arterial pressure (%MAP) calculated from pulse volume recording has been reported to predict all-cause mortality. We hypothesized that the %MAP would be helpful to screen for PAD in subjects with a normal ABI. We examined whether using a combination of the ABI and %MAP would provide greater diagnostic sensitivity for PAD than using the ABI alone.In this cross-sectional study, we retrospectively reviewed the medical records of patients who had undergone multiple detector computed tomography (MDCT) angiography of the lower extremities following measurement of the ABI with pulse volume recording. PAD was diagnosed based on MDCT angiography.A total of 215 lower extremities of 114 patients were included in our analyses. An optimal cut-off %MAP value of 42.5% was used to diagnose PAD based on MDCT in patients with an ABI > 0.90. Using a combination of an ABI < 0.90 and a %MAP >= 42.5% as diagnostic criteria for PAD resulted in better sensitivity (76.9%) than using the ABI alone (56.5% for an ABI < 0.90 and 63.4% for an ABI < 1.00). Using logistic regression analysis, we found that patients having both an ABI < 0.90 and an ABI > 0.90 with a %MAP >= 42.5% had a significantly higher risk of PAD than those having an ABI > 0.90 with a %MAP < 42.5% (odds ratio = 7.165, P = .006; odds ratio = 12.544, P < .001; respectively).Both the sensitivity and specificity were better when using a combination of an ABI <= 0.90 and a %MAP >= 42.5% than when using a low or borderline ABI. The %MAP is helpful for PAD screening in subjects with an ABI > 0.90. PMID- 30278589 TI - The relationship between oxidized low-density lipoprotein and related ratio and acute cerebral infarction. AB - This study aimed to study the value of oxidized low-density lipoprotein (OX-LDL) and related ratio in the diagnosis of acute cerebral infarction and the classification of acute cerebral infarction.Of the 129 patients enrolled in this study, 94 patients with acute cerebral infarction were assigned to the case group, and 35 healthy subjects were enrolled as control group (n = 35). And then the case group were divided into large-artery atherosclerosis (LAA) group (n = 61) and small-artery occlusion (SAO) group (n = 33) according to the TOAST classification standard. Plasma OX-LDL levels were determined by enzyme-linked immunosorbent assay. OX-LDL/total cholesterol (OX-LDL/TC), OX-LDL/high-density lipoprotein (OX-LDL/HDL), OX-LDL/LDL were calculated.There were significant differences in OX-LDL, OX-LDL/TC, OX-LDL/HDL, and OX-LDL/LDL in patients with acute cerebral infarction and those in control group (P < .001). The area under the receiver-operating characteristic curve of OX-LDL and related ratio was >0.7 (P < .001). There was a slight positive correlation between OX-LDL/TC and National Institutes of Health Stroke Scale score at admission (r = 0.265, P = .039) in the LAA group.OX-LDL, OX-LDL/TC, OX-LDL/HDL, and OX-LDL/LDL were closely related to acute cerebral infarction, especially with large atherosclerotic cerebral infarction. OX-LDL/TC can reflect the severity of acute cerebral infarction for LAA, but it cannot predict the short-term prognosis of acute cerebral infarction.

PMID- 30278599 TI - The Fourth Trimester of Pregnancy: Committing to Maternal Health and Well-Being Postpartum. AB - The postpartum period is a time of significant challenge and need as women adapt to hormonal and physical changes, recover from delivery, experience shifting family responsibilities, and endure sleep deprivation, all while caring for and nourishing their newborn. It is also a period of significant maternal health risk. Recent data on U.S. maternal mortality indicate a shift in the timing of maternal deaths over the past 10 years, with the majority of maternal deaths now occurring postpartum, from one day to one year after delivery. Postpartum care also marks a period of transition, as women shift from pregnancy-centered care to interpregnancy and primary care, yet current systems of care are marked by poor coordination of care between providers and patient care settings. Suboptimal postpartum follow-up is particularly worrisome for women with chronic health conditions or pregnancy complications who face both short- and long-term health risks. Given known challenges and medical risks, the single, 6-week postpartum visit women receive is woefully inadequate in addressing maternal health needs. Postpartum visits often fail to address the unique postpartum needs identified by mothers, inadequately connect women with primary care services, and have low attendance. Recognition of these unmet needs of "the Fourth Trimester" have led national organizations, including the American College of Obstetricians and Gynecologists (ACOG), to call for a restructuring of postpartum care to reduce postpartum and long-term morbidity and improve postpartum well-being. Rhode Island has several recent initiatives with the potential to improve outcomes for mother-baby dyads including the Baby Friendly Hospital Initiative (BFHI), the provision of long-acting reversible contraception (LARC) immediately postpartum, and the addition of HPV immunization postpartum. These initiatives remove barriers of access to care and provide vital women's health services prior to discharge. The Fourth Trimester provides a rich opportunity for maternal risk reduction and health promotion at a time when women are motivated and engaged with health care.

AB - In the last decade, reductions in HIV incidence have been observed across the United States. However, HIV continues to disproportionately impact gay, bisexual, and other men who have sex with men (MSM). In Rhode Island, rates of HIV diagnoses have decreased by 44% across all groups over the last decade. This success has been the result of close collaboration across multiple sectors. Different prevention approaches, including syringe exchange programs, community based HIV testing, condom distribution, HIV care and treatment, and pre-exposure prophylaxis (PrEP) have all contributed to the decline in HIV diagnoses across the state. In 2015, Rhode Island became one of the first states to sign on to the Joint United Nations Programme on HIV/AIDS "90-90-90" campaign to end the HIV epidemic by 2030. Intensified and innovative initiatives are needed to improve progress in HIV prevention and treatment, especially in populations who are most at risk. PMID- 30278603 TI - Instability in Insurance Coverage: The Impacts of Churn in Rhode Island, 2014 2017. AB - Churn, defined as a change in plan or a gap in insurance, is a problem in the United States that usually occurs as the result of changing life circumstances. Recent health reform perpetuates - rather than alleviates - churn because low- and middle- income individuals experience frequent changes in eligibility status. Our research asked: how common is churn in the non-group market and what are the health, financial, and emotional impacts on Rhode Island residents? This article draws examples from 31 life-history interviews and 188 enrollment observations conducted at Rhode Island's health insurance exchange from 2014-2017. The findings demonstrate that churn persists, despite state efforts to maximize enrollment, and causes poor health outcomes, financial insecurity, and increased stress. We argue that efforts to reform health insurance enrollment policies should be grounded in qualitative understandings of why people lose coverage and should seek to minimize barriers to maintaining continuous coverage. PMID- 30278604 TI - Financial Implications of Physician Specialty Choice. AB - PURPOSE: To examine the approximated financial outcomes of physicians by specialty and to determine whether these correlate with mean USMLE Step 1 scores. METHODS: Specialty-specific data from the Association of American Medical Colleges Careers in Medicine website were analyzed for total length of training, mean USMLE Step 1 scores, average hours worked per week, and median clinical practice salary for physicians. Hourly wage and estimated net worth at retirement were calculated. Coefficients of determination (R2) were calculated to evaluate the relationships between hourly wage, annual salary, and estimated net worth at retirement with competitiveness as measured by USMLE Step 1 scores of matched residents. RESULTS: Across all 37 specialties studied, the mean hourly wage was $136 +/- $40, ranging from $78 (Geriatrics) to $249 (Neurosurgery). Mean weekly hours worked across all specialties was 54.6 +/- 6.4, ranging from 43.4 (Pediatric Emergency Medicine) to 71.1 (Vascular Surgery). At retirement, the mean estimated net worth for all physicians was $4,517,600 +/- $1,793,095, ranging from $1,927,779 (Child & Adolescent Psychiatry) to $8,947,885 (Neurosurgery). Step 1 scores, as a marker of specialty competiveness, correlate with specialty compensation - the strongest association was with hourly wage (R2 = 0.6678), then annual salary (R2 = 0.6424), and finally by estimated net worth at retirement (R2 = 0.6158). CONCLUSION: In this study, mean Step 1 scores for each medical specialty were positively correlated with compensation, including absolute salary, hourly wage and estimated net worth at retirement.

Limnephilidae): I. Histology, histochemistry, and ultrastructure of the silk glands. AB - As part of a study on trichopteran silk secretion, the histology, histochemistry, and ultrastructure of the silk glands of two species of limnephilid trichopteran larvae, Pycnopsyche guttifer (Walk.) and Neophylax concinnus McL., were investigated. The silk glands consist of three anatomically distinct regions: a long, posterior silk-secreting region; a shorter, anterior conducting tube; and a terminal press/common duct. In Pycnopsyche, there is also a modified bulbous region between the secreting and conducting areas. Each anatomical region has a distinct cell type. There are two structurally and histochemically different components of the secretion in the glandular lumen: a core and a peripheral layer. Both components are produced all along the gland and are principally proteinaceous. However, the peripheral layer is also PAS and alcian blue (pH. 2.5) positive and shows beta-metachromasia with toluidine blue (pH 3.5), indicating the presence of both neutral and acidic polysaccharides. PMID- 30278607 TI - Exocytosis of neurosecretory granules from the crustacean sinus gland in freeze fracture. AB - Exocytosis is clearly shown in freeze-fracture preparations to be the mechanism for neurosecretion granule release from axon endings in the crayfish sinus gland. The cytoplasmic leaflet (A-face) of axon ending membrane is characterized by randomly situated depressions representing invaginations of the axolemma, which are in contact with limiting membranes of neurohormone granules in the subjacent cytoplasm. The extracellular leaflet (B-face) of the axolemma at release sites exhibits complementary volcano-shaped protrusions which are cross-fractures through necks of channels formed by invaginating plasma membrane in contact with underlying neurosecretion granules. Structural variation in B-face protrusions is consistent with a spectrum of exocytotic profiles in various stages of formation, and with granules at different stages of passage out of the endings. Evidence in this study suggests that formation of exocytotic structures may begin by alteration of axon membrane structure at the neurosecretory ending-hemolymph interface prior to contact of the neurohormone granules with the axolemma. Limiting membranes of neurosecretory granules exhibit protrusions which appear to interconnect granules adjacent to release sites and to attach granules to the axolemma. Freeze-fracture is clearly shown to be an invaluable tool for monitoring the degree of exocytosis exhibited by sinus glands under normal conditions and under experimental acceleration of hormone release. This technique is capable therefore, of detecting slight increases in numbers of exocytotic profiles much more quickly and accurately than the examination of random thin sections.

The stability and antigenicity of a targeted synthesized recombinant fusion protein consisting of a truncated core and NS3 (rC/N) of HCV had been predicted. Although safe antigens, recombinant proteins are not efficacious vaccines without adjuvants. The present study evaluated the immunogenicity of rC/N as a bipartite antigen accompanied by Neisseria meningitidis serogroup B outer membrane vesicles (NMB OMVs) in BALB/c mice. Methods: The NMB OMVs were produced and evaluated accurately. The administrations were as follows: rC/N-OMV, rC/N-Freund's complete/incomplete adjuvant (CIA), rC/N MF59, rC/N, OMV, MF59, and PBS. The production of Th1 (IFN-gamma, IL-2)/Th2 (IL 4)/Th17 (IL-17) cytokines and granzyme B (cytotoxic indicator) by splenic mononuclear cells and the humoral concentration of total IgG/IgG1 (Th2)/IgG2a (Th1) in sera of mice were measured using mouse ELISA kits. Results: Concentrations of Th1/Th2/Th17 cytokines, granzyme B, and immunoglobulins in the spleens and sera of immunized mice, which had received antigen plus each adjuvant (rC/N-OMV, rC/N-Freund's CIA and rC/N-MF59), significantly raised compared to the controls (rC/N, OMV, MF59 and PBS). Th1-type responses were dominant over Th2 type responses in vaccinated mice with rC/N-OMV, and Th2 type responses increased dominantly in vaccinated mice with rC/N-MF59 (p < 0.05). Discssion: NMB OMVs were able to increase Th1 immune responses dramatically more than MF59 and Freund's CIA. The formulation of rC/N with NMB OMVs showed its ability to induce Th1, Th2, and Th17 immune responses. rC/N-NMB OMVs is a promising approach for the development of an HCV therapeutic vaccine.

AB - Metal-halide perovskites are promising lasing materials for the realization of monolithically integrated laser sources, the key components of silicon photonic integrated circuits (PICs). Perovskites can be deposited from solution and require only low-temperature processing, leading to significant cost reduction and enabling new PIC architectures compared to state-of-the-art lasers realized through the costly and inefficient hybrid integration of III-V semiconductors. Until now, however, due to the chemical sensitivity of perovskites, no microfabrication process based on optical lithography (and, therefore, on existing semiconductor manufacturing infrastructure) has been established. Here, the first methylammonium lead iodide perovskite microdisc lasers monolithically integrated into silicon nitride PICs by such a top-down process are presented. The lasers show a record low lasing threshold of 4.7 MUJcm-2 at room temperature for monolithically integrated lasers, which are complementary metal-oxide semiconductor compatible and can be integrated in the back-end-of-line processes. PMID- 30278612 TI - Protein Expression Landscape Defines the Differentiation Potential Specificity of Adipogenic and Myogenic Precursors in the Skeletal Muscle. AB - The balance of adipogenic and myogenic differentiation of skeletal muscle-derived mesenchymal stem cells is particularly important in muscle development and intramuscular fat deposition. This study aimed to explore the differential regulation between adipogenic and myogenic precursors by comparative analysis of their global proteome expression profile. Adipogenic and myogenic precursors isolated from neonatal porcine longissimus dorsi muscle by the preplate method were verified for their unique and distinct differentiation potential under myogenic or adipogenic induction. A total of 433 differentially expressed proteins (DEP) ( P < 0.05 and FC > 1.20 or <0.83) between adipogenic and myogenic precursors were detected via a tandem mass tag (TMT)-coupled LC-MS/MS approach, including 339 up-regulated and 94 down-regulated proteins in myogenic precursors compared with adipogenic precursors. On the basis of functional annotation and enrichment analysis of 433 DEP, adipogenic and myogenic precursors showed significantly different metabolic pattern of energy substances and differential regulations of gene expression, cell structure and development, ion homeostasis, and cell motility and migration. Three pathways including PPAR signaling pathway, phosphatidylinositol signaling system, and autophagy signaling pathway, which was differentially regulated between adipogenic and myogenic precursors, was also discovered to play crucial roles in cell differentiation. In conclusion, these differentiated regulation patterns between the two cell subsets of mesenchymal precursors together defines their differentiation potential specificity.

AB - This paper studies a billiards-like microscopic heat conduction model, which describes the dynamics of gas molecules in a long tube with thermalized boundary. We numerically investigate the law of energy exchange between adjacent cells. A stochastic energy exchange model that preserves these properties is then derived. We further numerically justified that the stochastic energy exchange model preserves the ergodicity and the thermal conductivity of the original billiard model. PMID- 30278615 TI - Phase synchronization on spatially embedded duplex networks with total cost constraint. AB - Synchronization on multiplex networks has attracted increasing attention in the past few years. We investigate collective behaviors of Kuramoto oscillators on single layer and duplex spacial networks with total cost restriction, which was introduced by Li et al. [Phys. Rev. Lett. 104, 018701 (2010)] and termed as the Li network afterwards. We first explore how the topology of the network influences synchronizability of Kuramoto oscillators on single layer Li networks and find that the closer the Li network is to a regular lattice, the more difficult for it to evolve into synchronization. Then, we investigate synchronizability of duplex Li networks and find that the existence of inter layer interaction can greatly enhance inter-layer and global synchronizability. When the inter-layer coupling strength is larger than a certain critical value, inter-layer synchronization will always occur. Furthermore, on single layer Li networks, nodes with larger degrees reach global synchronization more easily than those with smaller degrees, while on duplex Li networks, due to inter-layer interaction, this phenomenon becomes much less obvious. The results are important for us to gain insight into collective behaviors of many real-world complex systems which inherently possess multiplex architecture. PMID- 30278616 TI - The modulation of multiple phases leading to the modified Korteweg-de Vries equation. AB - This paper seeks to derive the modified Korteweg-de Vries (mKdV) equation using a novel approach from systems generated from abstract Lagrangians possessing a two parameter symmetry group. The method utilises a modified modulation approach, which results in the mKdV emerging with coefficients related to the conservation laws possessed by the original Lagrangian system. Alongside this, an adaptation of the method of Kuramoto is developed, providing a simpler mechanism to determine the coefficients of the nonlinear term. The theory is illustrated using two examples of physical interest, one in stratified hydrodynamics and another using a coupled Nonlinear Schrodinger model, to illustrate how the criterion for the mKdV equation to emerge may be assessed and its coefficients generated. PMID- 30278617 TI - Hydrodynamic spin states. AB - We present the results of a theoretical investigation of hydrodynamic spin states, wherein a droplet walking on a vertically vibrating fluid bath executes orbital motion despite the absence of an applied external field. In this regime, the walker's self-generated wave force is sufficiently strong to confine the walker to a circular orbit. We use an integro-differential trajectory equation for the droplet's horizontal motion to specify the parameter regimes for which the innermost spin state can be stabilized. Stable spin states are shown to exhibit an analog of the Zeeman effect from quantum mechanics when they are placed in a rotating frame. PMID- 30278618 TI - Pilot-wave dynamics of two identical, in-phase bouncing droplets. AB - A droplet bouncing on the surface of a vibrating liquid bath can move horizontally guided by the wave it produces on impacting the bath. The wave itself is modified by the environment, and thus, the interactions of the moving droplet with the surroundings are mediated through the wave. This forms an example of a pilot-wave system. Taking the Oza-Rosales-Bush description for walking droplets as a theoretical pilot-wave model, we investigate the dynamics of two interacting identical, in-phase bouncing droplets theoretically and numerically. A remarkably rich range of behaviors is encountered as a function of the two system parameters, the ratio of inertia to drag, kappa , and the ratio of wave forcing to drag, beta . The droplets typically travel together in a tightly bound pair, although they unbind when the wave forcing is large and inertia is small or inertia is moderately large and wave forcing is moderately small. Bound pairs can exhibit a range of trajectories depending on parameter values, including straight lines, sub-diffusive random walks, and closed loops. The droplets themselves may maintain their relative positions, oscillate toward and away from one another, or interchange positions regularly or chaotically as they travel. We explore these regimes and others and the bifurcations between them through analytic and numerical linear stability analyses and through fully nonlinear numerical simulation. PMID- 30278619 TI - Effects of external forcing on evolutionary games in complex networks. AB - How did cooperation evolve in a complex network is an intensely investigated problem. Many mechanisms that promote cooperation have been proposed within the framework of the evolutionary game theory. Motivated by the fact that people in society or even a certain group are often controlled by a variety of simple rules, we present an external forcing mechanism to analyze the underlying reasons of widespread cooperation in this paper. In detail, we model the agents on a simple regular network, on which the learning method is controlled by external forcing mechanism, and prisoner's dilemma has been applied to describe the interaction of agents. By conducting large-scale Monte Carlo simulations, we can easily draw a conclusion that this mechanism can promote cooperation efficiently. In addition, we also show that the proposed mechanism is effective for the cooperation promotion for other game models, such as snowdrift game and multigames. Taken together, the mechanism of external forcing on the evolutionary game is a strong promoter of cooperation even under a severe temptation condition, which has a practical significance and will provide new insight into the analysis and control of cooperative strategy in the complex network for the further research. PMID- 30278620 TI - Efficient manifolds tracing for planar maps. AB - In this work, we introduce an exact calculation method and an approximation technique for tracing the invariant manifolds of unstable periodic orbits of planar maps. The exact method relies on an adaptive refinement procedure that prevents redundant calculations occurring in other approaches, and the approximated method relies on a novel interpolation approach based on normal displacement functions. The resulting approximated manifold is precise when compared to the exact one, and its relative computational cost falls like the inverse of the manifold length. To present the tracing method, we obtain the invariant manifolds of the Chirikov-Taylor map, and as an application we illustrate the transition from homoclinic to heteroclinic chaos in the Duffing oscillator that leads from localized chaos to global chaotic motion. PMID- 30278621 TI - Introduction to dynamics of manufacturing supply networks. AB - Manufacturing supply networks are complex dynamic networks that play a crucial role in the economy. Nevertheless, there are so far only few studies that apply modern tools of network science and dynamical system theory to the analysis of these networks. Here, we provide a brief introduction to these types of networks highlighting their basic organization, current challenges, and selected previous work. This paper serves as an introduction to a focus topic consisting of five papers by experts on supply network dynamics. PMID- 30278622 TI - Multilacunarity as a spatial multiscale multi-mass morphometric of change in the meso-architecture of plant parenchyma tissue. AB - The lacunarity index (monolacunarity) averages the behavior of variable size structures in a binary image. The generalized lacunarity concept (multilacunarity) on the basis of generalized distribution moments is an appealing model that can account for differences in the mass content at different scales. The model was tested previously on natural images [J. Vernon-Carter et al., Physica A 388, 4305 (2009)]. Here, the computational aspects of multilacunarity are validated using synthetic binary images that consist of random maps, spatial stochastic patterns, patterns with circular or polygonal elements, and a plane fractal. Furthermore, monolacunarity and detrended fluctuation analysis were employed to quantify the mesostructural changes in the intercellular air spaces of frozen-thawed parenchymatous tissue of pome fruit [N. A. Valous et al., J. Appl. Phys. 115, 064901 (2014)]. Here, the aim is to further examine the coherence of the multilacunarity model for quantifying the mesostructural changes in the intercellular air spaces of parenchymatous tissue of pome and stone fruit, acquired with X-ray microcomputed tomography, after storage and ripening, respectively. The multilacunarity morphometric is a multiscale multi-mass fingerprint of spatial pattern composition, assisting the exploration of the effects of metabolic and physiological activity on the pore space of plant parenchyma tissue. PMID- 30278623 TI - Walking droplets correlated at a distance. AB - Bouncing fluid droplets can walk on the surface of a vibrating bath forming a wave-particle association. Walking droplets have many quantum-like features. Research efforts are continuously exploring quantum analogues and respective limitations. Here, we demonstrate that two oscillating particles (millimetric droplets) confined to separate potential wells exhibit correlated dynamical features, even when separated by a large distance. A key feature is the underlying wave mediated dynamics. The particles' phase space dynamics is given by the system as a whole and cannot be described independently. Numerical phase space histograms display statistical coherence; the particles' intricate distributions in phase space are statistically indistinguishable. However, removing one particle changes the phase space picture completely, which is reminiscent of entanglement. The model here presented also relates to nonlinearly coupled oscillators where synchronization can break out spontaneously. The present oscillator-coupling is dynamic and can change intensity through the underlying wave field as opposed to, for example, the Kuramoto model where the coupling is pre-defined. There are some regimes where we observe phase-locking or, more generally, regimes where the oscillators are statistically indistinguishable in phase-space, where numerical histograms display their (mutual) most likely amplitude and phase. PMID- 30278624 TI - Walking droplets in a circular corral: Quantisation and chaos. AB - A millimetric liquid droplet may walk across the surface of a vibrating liquid bath through a resonant interaction with its self-generated wavefield. Such walking droplets, or "walkers," have attracted considerable recent interest because they exhibit certain features previously believed to be exclusive to the microscopic, quantum realm. In particular, the intricate motion of a walker confined to a closed geometry is known to give rise to a coherent wave-like statistical behavior similar to that of electrons confined to quantum corrals. Here, we examine experimentally the dynamics of a walker inside a circular corral. We first illustrate the emergence of a variety of stable dynamical states for relatively low vibrational accelerations, which lead to a double quantisation in angular momentum and orbital radius. We then characterise the system's transition to chaos for increasing vibrational acceleration and illustrate the resulting breakdown of the double quantisation. Finally, we discuss the similarities and differences between the dynamics and statistics of a walker inside a circular corral and that of a walker subject to a simple harmonic potential. PMID- 30278625 TI - Hong-Ou-Mandel-like two-droplet correlations. AB - We present a numerical study of two-droplet pair correlations for in-phase droplets walking on a vibrating bath. Two such walkers are launched toward a common point of intersection. As they approach, their carrier waves may overlap and the droplets have a non-zero probability of forming a two-droplet bound state. The likelihood of such pairing is quantified by measuring the probability of finding the droplets in a bound state at late times. Three generic types of two-droplet correlations are observed: promenading, orbiting, and chasing pair of walkers. For certain parameters, the droplets may become correlated for certain initial path differences and remain uncorrelated for others, while in other cases, the droplets may never produce droplet pairs. These observations pave the way for further studies of strongly correlated many-droplet behaviors in the hydrodynamical quantum analogs of bouncing and walking droplets. PMID- 30278626 TI - The interaction of a walking droplet and a submerged pillar: From scattering to the logarithmic spiral. AB - Millimetric droplets may walk across the surface of a vibrating fluid bath, propelled forward by their own guiding or "pilot" wave field. We here consider the interaction of such walking droplets with a submerged circular pillar. While simple scattering events are the norm, as the waves become more pronounced, the drop departs the pillar along a path corresponding to a logarithmic spiral. The system behavior is explored both experimentally and theoretically, using a reduced numerical model in which the pillar is simply treated as a region of decreased wave speed. A trajectory equation valid in the limit of weak droplet acceleration is used to infer an effective force due to the presence of the pillar, which is found to be a lift force proportional to the product of the drop's walking speed and its instantaneous angular speed around the post. This system presents a macroscopic example of pilot-wave-mediated forces giving rise to apparent action at a distance. PMID- 30278627 TI - Ratcheting droplet pairs. AB - Millimetric droplets may be levitated on the surface of a vibrating fluid bath. Eddi et al. [Europhys. Lett. 82, 44001 (2008)] demonstrated that when a pair of levitating drops of unequal size are placed nearby, they interact through their common wavefield in such a way as to self-propel through a ratcheting mechanism. We present the results of an integrated experimental and theoretical investigation of such ratcheting pairs. Particular attention is given to characterizing the dependence of the ratcheting behavior on the droplet sizes and vibrational acceleration. Our experiments demonstrate that the quantized inter drop distances of a ratcheting pair depend on the vibrational acceleration, and that as this acceleration is increased progressively, the direction of the ratcheting motion may reverse up to four times. Our simulations highlight the critical role of both the vertical bouncing dynamics of the individual drops and the traveling wave fronts generated during impact on the ratcheting motion, allowing us to rationalize the majority of our experimental findings. PMID- 30278628 TI - Complex spatiotemporal behavior and coherent excitations in critically-coupled chains of neural circuits. AB - We investigate a critically-coupled chain of nonlinear oscillators, whose dynamics displays complex spatiotemporal patterns of activity, including regimes in which glider-like coherent excitations move about and interact. The units in the network are identical simple neural circuits whose dynamics is given by the Wilson-Cowan model and are arranged in space along a one-dimensional lattice with nearest neighbor interactions. The interactions follow an alternating sign rule, and hence the "synaptic matrix" M embodying them is tridiagonal antisymmetric and has purely imaginary (critical) eigenvalues. The model illustrates the interplay of two properties: circuits with a complex internal dynamics, such as multiple stable periodic solutions and period doubling bifurcations, and coupling with a "critical" synaptic matrix, i.e., having purely imaginary eigenvalues. In order to identify the dynamical underpinnings of these behaviors, we explored a discrete-time coupled-map lattice inspired by our system: the dynamics of the units is dictated by a chaotic map of the interval, and the interactions are given by allowing the critical coupling to act for a finite period tau , thus given by a unitary matrix U=exp?(tau2M) . It is now explicit that such critical couplings are volume-preserving in the sense of Liouville's theorem. We show that this map is also capable of producing a variety of complex spatiotemporal patterns including gliders, like our original chain of neural circuits. Our results suggest that if the units in isolation are capable of featuring multiple dynamical states, then local critical couplings lead to a wide variety of emergent spatiotemporal phenomena. PMID- 30278629 TI - A coupled focusing-defocusing complex short pulse equation: Multisoliton, breather, and rogue wave. AB - Nonlinear Schrodinger equation, short pulse equation, and complex short pulse equation have important applications in nonlinear optics. They can be derived from the Maxwell equations. In this paper, we investigate a coupled focusing defocusing complex short pulse equation. The bright-bright, bright-dark, and dark dark soliton solutions of the coupled focusing-defocusing complex short pulse equation are constructed. Furthermore, the breather solutions are derived from the dark soliton solution. The rogue wave solutions are also constructed. The dynamics and the asymptotic behavior of the soliton solutions are analyzed, which reveals a fact that the bright-bright soliton collision can be either elastic or inelastic, but the bright-dark and dark-dark soliton collision can only be elastic.

AB - Recent experiments on walking droplets in an annular cavity showed the existence of complex dynamics including chaotically changing velocity. This article presents models, influenced by the kicked rotator/standard map, for both single and multiple droplets. The models are shown to achieve both qualitative and quantitative agreement with the experiments, and make predictions about heretofore unobserved behavior. Using dynamical systems techniques and bifurcation theory, the single droplet model is analyzed to prove dynamics suggested by the numerical simulations. PMID- 30278631 TI - Bouncing droplet dynamics above the Faraday threshold. AB - We present the results of an experimental investigation of the dynamics of droplets bouncing on a vibrating fluid bath for forcing accelerations above the Faraday threshold. Two distinct fluid viscosity and vibrational frequency combinations (20 cS-80 Hz and 50 cS-50 Hz) are considered, and the dependence of the system behavior on drop size and vibrational acceleration is characterized. A number of new dynamical regimes are reported, including meandering, zig-zagging, erratic bouncing, coalescing, and trapped regimes. Particular attention is given to the regime in which droplets change direction erratically and exhibit a dynamics akin to Brownian motion. We demonstrate that the effective diffusivity increases with vibrational acceleration and decreases with drop size, as suggested by simple scaling arguments. PMID- 30278632 TI - Introduction to focus issue on hydrodynamic quantum analogs. AB - Hydrodynamic quantum analogs is a nascent field initiated in 2005 by the discovery of a hydrodynamic pilot-wave system [Y. Couder, S. Protiere, E. Fort, and A. Boudaoud, Nature 437, 208 (2005)]. The system consists of a millimetric droplet self-propeling along the surface of a vibrating bath through a resonant interaction with its own wave field [J. W. M. Bush, Annu. Rev. Fluid Mech. 47, 269-292 (2015)]. There are three critical ingredients for the quantum like behavior. The first is "path memory" [A. Eddi, E. Sultan, J. Moukhtar, E. Fort, M. Rossi, and Y. Couder, J. Fluid Mech. 675, 433-463 (2011)], which renders the system non-Markovian: the instantaneous wave force acting on the droplet depends explicitly on its past. The second is the resonance condition between droplet and wave that ensures a highly structured monochromatic pilot wave field that imposes an effective potential on the walking droplet, resulting in preferred, quantized states. The third ingredient is chaos, which in several systems is characterized by unpredictable switching between unstable periodic orbits. This focus issue is devoted to recent studies of and relating to pilot-wave hydrodynamics, a field that attempts to answer the following simple but provocative question: Might deterministic chaotic pilot-wave dynamics underlie quantum statistics? PMID- 30278633 TI - Gravitational thermal flows of liquid metals in 3D variable cross-section containers: Transition from low-dimensional to high-dimensional chaos. AB - This study extends the numerical results presented in author's past work [M. Lappa and H. Ferialdi, Phys. Fluids 29(6), 064106 (2017)] about the typical instabilities of thermogravitational convection (the so-called Hadley flow) in containers with inclined (converging or diverging) walls. The flow is now allowed to develop along the third dimension (z). In a region of the space of parameters where the two-dimensional solutions were found to be relatively regular in time and with a simple structure in space (supporting transverse waves propagating either in the downstream or in the upstream direction), the 3D flow exhibits either waves traveling along the spanwise direction or spatially disordered and chaotic patterns. In order to identify the related mechanisms, we analyze the competition between hydrodynamic and hydrothermal (Oscillatory Longitudinal Roll) modes of convection for different conditions. A peculiar strategy of analysis is implemented, which, on the one hand, exploits the typical properties of systems developing coexisting branches of solutions ("multiple" states) and their sensitivity to a variation of the initial conditions and, on the other hand, can force such systems to select a specific category of disturbances (by enabling or disabling the related "physical" mechanisms). It is shown that hydrodynamic modes can produce early transition to chaos. The dimensionality of such states is investigated through evaluation of the "fractal" (correlation) dimension on the basis of the algorithm by Grassberger and Procaccia. When low-dimensional chaos is taken over by high-dimensional chaos, the flow develops a recognisable interval of scales where turbulence obeys the typical laws of the so-called "inertial range" and produces small-scale features in agreement with available Kolmogorov estimates. PMID- 30278634 TI - Mean field phase synchronization between chimera states. AB - We study two-layer networks of identical phase oscillators. Each individual layer is a ring network for which a non-local intra-layer coupling leads to the formation of a chimera state. The number of oscillators and their natural frequencies is in general different across the layers. We couple the phases of individual oscillators in one layer to the phase of the mean field of the other layer. This coupling from the mean field to individual oscillators is done in both directions. For a sufficient strength of this inter-layer coupling, the phases of the mean fields lock across the two layers. In contrast, both layers continue to exhibit chimera states with no locking between the phases of individual oscillators across layers, and the two mean field amplitudes remain uncorrelated. Hence, the networks' mean fields show phase synchronization which is analogous to the one between low-dimensional chaotic oscillators. The required coupling strength to achieve this mean field phase synchronization increases with the mismatches in the network sizes and the oscillators' natural frequencies. PMID- 30278635 TI - Effect of noise amplification during the transition to amplitude death in coupled thermoacoustic oscillators. AB - We present a systematic investigation of the effect of external noise on the dynamics of a system of two coupled prototypical thermoacoustic oscillators, horizontal Rijke tubes, using a mathematical model. We focus on the possibility of amplitude death (AD), which is observed in the deterministic model of coupled thermoacoustic oscillators as studied by Thomas et al. [Chaos 28, 033119 (2018)], in the presence of noise. Although a complete cessation of oscillations or AD is not possible in the stochastic case, we observe a significant reduction in the amplitude of coupled limit cycle oscillations (LCOs) with the application of strong coupling. Furthermore, as we increase the noise intensity, a sudden drop in the amplitude of pressure oscillations at the transition from LCO to AD, observed in the noise free case, is no longer discernible because of the amplification of noise in AD state. During this transition from LCO to AD, we notice a qualitative change in the distribution of the pressure amplitude from bimodal to unimodal. Furthermore, in order to demarcate the boundary of the transition from LCO and AD in the noisy case, we use 80 % suppression in the amplitude of LCO, which generally occurs in the parameter range over which this qualitative change in the pressure distribution happens, as a threshold. With the help of bifurcation diagrams, we show a qualitative change as well as a reduction in the size of amplitude suppression zones that happen due to the increase in noise intensity. We also observe the relative ease of suppressing the amplitude of LCO with time-delay coupling when detuning and dissipative couplings are introduced between the two thermoacoustic oscillators in the presence of noise. PMID- 30278636 TI - Synchronization of chimera states in a multiplex system of phase oscillators with adaptive couplings. AB - We study the interaction of chimera states in multiplex two-layer systems, where each layer represents a network of interacting phase oscillators with adaptive couplings. A feature of this study is the consideration of synchronization processes for a wide range of chimeras with essentially different properties, which are achieved due to the use of different types of coupling adaptation within isolated layers. We study the effect of forced synchronization of chimera states under unidirectional action between layers. This process is accompanied not only by changes in the frequency characteristics of the oscillators, but also by the transformation of the structure of interactions within the slave layer that become close to the properties of the master layer of the system. We show that synchronization close to identical is possible, even in the case of interaction of chimeras with essentially different structural properties (number and size of coherent clusters) formed by means of a relatively large parameter mismatch between the layers. In the case of mutual action of the layers in chimera states, we found a number of new scenarios of the multiplex system behavior along with those already known, when identical or different chimeras appear in both layers. In particular, we have shown that a fairly weak interlayer coupling can lead to suppression of the chimera state when one or both layers of the system demonstrate an incoherent state. On the contrary, a strong interlayer coupling provides a complete synchronization of the layer dynamics, accompanied by the appearance of multicluster states in the system's layers. PMID- 30278637 TI - Strange nonchaotic and chaotic attractors in a self-excited thermoacoustic oscillator subjected to external periodic forcing. AB - We experimentally investigate the synchronization dynamics of a self-excited thermoacoustic system forced beyond its phase-locked state. The system consists of a laminar premixed flame in a tube combustor subjected to periodic acoustic forcing. On increasing the forcing amplitude above that required for phase locking, we find that the system can transition out of phase locking and into chaos, which is consistent with the Afraimovich-Shilnikov theorem for the breakdown of a phase-locked torus. However, we also find some unexpected behavior, most notably the emergence of a strange nonchaotic attractor (SNA) before the onset of chaos. We verify the existence of the SNA and chaotic attractor by examining the correlation dimension, the autocorrelation function, the power-law scaling in the Fourier amplitude spectrum, the permutation entropy in a pseudoperiodic surrogate test, and the permutation spectrum. In summary, this study explores the SNA and chaotic dynamics of a thermoacoustic system forced beyond its phase-locked state, opening up new pathways for the development of alternative strategies to control self-excited thermoacoustic oscillations in combustion devices such as gas turbines and rocket engines. PMID- 30278638 TI - Faraday-Talbot effect: Alternating phase and circular arrays. AB - A hydrodynamic analog to the optical Talbot effect may be realized on the surface of a vertically shaken fluid bath when a periodic array of pillars protrudes from the fluid surface. When the pillar spacing is twice or one and a half times the Faraday wavelength, we observe repeated images of the pillars projected in front of the array. Sloshing inter-pillar ridges act as sources of Faraday waves, giving rise to self-images. Here, we explore the emergence of Faraday-Talbot patterns when the sloshing ridges between pillars have alternating phases. We present a simple model of linear wave superposition and use it to calculate the expected self-image locations, comparing them to experimental observations. We explore how alternating phase sources affect the Faraday-Talbot patterns for linear and circular arrays of pillars, where curvature allows for magnification and demagnification of the self-imaging pattern. The use of an underlying wavefield is a subject of current interest in hydrodynamic quantum analog experiments, as it may provide a means to trap walking droplets. PMID- 30278639 TI - A review of the theoretical modeling of walking droplets: Toward a generalized pilot-wave framework. AB - The walking droplet system has extended the range of classical systems to include several features previously thought to be exclusive to quantum systems. We review the hierarchy of analytic models that have been developed, on the basis of various simplifying assumptions, to describe droplets walking on a vibrating fluid bath. Particular attention is given to detailing their successes and failures in various settings. Finally, we present a theoretical model that may be adopted to explore a more generalized pilot-wave framework capable of further extending the phenomenological range of classical pilot-wave systems beyond that achievable in the laboratory. PMID- 30278640 TI - Delayed loss of stability due to the slow passage through Hopf bifurcations in reaction-diffusion equations. AB - This article presents the delayed loss of stability due to slow passage through Hopf bifurcations in reaction-diffusion equations with slowly-varying parameters, generalizing a well-known result about delayed Hopf bifurcations in analytic ordinary differential equations to spatially-extended systems. We focus on the Hodgkin-Huxley partial differential equation (PDE), the cubic Complex Ginzburg Landau PDE as an equation in its own right, the Brusselator PDE, and a spatially extended model of a pituitary clonal cell line. Solutions which are attracted to quasi-stationary states (QSS) sufficiently before the Hopf bifurcations remain near the QSS for long times after the states have become repelling, resulting in a significant delay in the loss of stability and the onset of oscillations. Moreover, the oscillations have large amplitude at onset, and may be spatially homogeneous or inhomogeneous. Space-time boundaries are identified that act as buffer curves beyond which solutions cannot remain near the repelling QSS, and hence before which the delayed onset of oscillations must occur, irrespective of initial conditions. In addition, a method is developed to derive the asymptotic formulas for the buffer curves, and the asymptotics agree well with the numerically observed onset in the Complex Ginzburg-Landau (CGL) equation. We also find that the first-onset sites act as a novel pulse generation mechanism for spatio-temporal oscillations. PMID- 30278641 TI - Exploring orbital dynamics and trapping with a generalized pilot-wave framework. AB - We explore the effects of an imposed potential with both oscillatory and quadratic components on the dynamics of walking droplets. We first conduct an experimental investigation of droplets walking on a bath with a central circular well. The well acts as a source of Faraday waves, which may trap walking droplets on circular orbits. The observed orbits are stable and quantized, with preferred radii aligning with the extrema of the well-induced Faraday wave pattern. We use the stroboscopic model of Oza et al. [J. Fluid Mech. 737, 552-570 (2013)] with an added potential to examine the interaction of the droplet with the underlying well-induced wavefield. We show that all quantized orbits are stable for low vibrational accelerations. Smaller orbits may become unstable at higher forcing accelerations and transition to chaos through a path reminiscent of the Ruelle Takens-Newhouse scenario. We proceed by considering a generalized pilot-wave system in which the relative magnitudes of the pilot-wave force and drop inertia may be tuned. When the drop inertia is dominated by the pilot-wave force, all circular orbits may become unstable, with the drop chaotically switching between them. In this chaotic regime, the statistically stationary probability distribution of the drop's position reflects the relative instability of the unstable circular orbits. We compute the mean wavefield from a chaotic trajectory and confirm its predicted relationship with the particle's probability density function. PMID- 30278642 TI - Time dependent stability margin in multistable systems. AB - We propose a novel technique to analyze multistable, non-linear dynamical systems. It enables one to characterize the evolution of a time-dependent stability margin along stable periodic orbits. By that, we are able to indicate the moments along the trajectory when the stability surplus is minimal, and even relatively small perturbation can lead to a tipping point. We explain the proposed approach using two paradigmatic dynamical systems, i.e., Rossler and Duffing oscillators. Then, the method is validated experimentally using the rig with a double pendulum excited parametrically. Both numerical and experimental results reveal significant fluctuations of sensitivity to perturbations along the considered periodic orbits. The proposed concept can be used in multiple applications including engineering, fluid dynamics, climate research, and photonics. PMID- 30278643 TI - High-dimensional dynamics in a single-transistor oscillator containing Feynman Sierpinski resonators: Effect of fractal depth and irregularity. AB - Fractal structures pervade nature and are receiving increasing engineering attention towards the realization of broadband resonators and antennas. We show that fractal resonators can support the emergence of high-dimensional chaotic dynamics even in the context of an elementary, single-transistor oscillator circuit. Sierpinski gaskets of variable depth are constructed using discrete capacitors and inductors, whose values are scaled according to a simple sequence. It is found that in regular fractals of this kind, each iteration effectively adds a conjugate pole/zero pair, yielding gradually more complex and broader frequency responses, which can also be implemented as much smaller Foster equivalent networks. The resonators are instanced in the circuit as one-port devices, replacing the inductors found in the initial version of the oscillator. By means of a highly simplified numerical model, it is shown that increasing the fractal depth elevates the dimension of the chaotic dynamics, leading to high order hyperchaos. This result is overall confirmed by SPICE simulations and experiments, which however also reveal that the non-ideal behavior of physical components hinders obtaining high-dimensional dynamics. The issue could be practically mitigated by building the Foster equivalent networks rather than the verbatim fractals. Furthermore, it is shown that considerably more complex resonances, and consequently richer dynamics, can be obtained by rendering the fractal resonators irregular through reshuffling the inductors, or even by inserting a limited number of focal imperfections. The present results draw attention to the potential usefulness of fractal resonators for generating high dimensional chaotic dynamics, and underline the importance of irregularities and component non-idealities. PMID- 30278644 TI - Bouncing ball on a vibrating periodic surface. AB - We present an investigation of a partially elastic ball bouncing on a vertically vibrated sinusoidal surface. Following the work of McBennett and Harris [Chaos 26, 093105 (2016)], we begin by demonstrating that simple periodic vertical bouncing at a local minimum of the surface becomes unstable when the local curvature exceeds a critical value. The resulting instability gives rise to a period doubling cascade and results in persistent horizontal motion of the ball. Following this transition to horizontal motion, periodic "walking" states-where the ball bounces one wavelength over each vibration cycle-are possible and manifest for a range of parameters. Furthermore, we show that net horizontal motion in a preferred direction can be induced by breaking the left-right symmetry of the periodic topography. PMID- 30278645 TI - Delay Cournot duopoly models revisited. AB - In considering economic dynamics, it has been known that time delays are inherent in economic phenomena and could be crucial sources for oscillatory behavior. The main aim of this study is to shed light on what effects the delays can generate. To this end, different models of Cournot duopoly with different delays are built in a continuous time framework and their local and global dynamics are analytically and numerically examined. Three major findings are obtained. First, the stability switching conditions are analytically constructed. Second, it is numerically demonstrated that different lengths of the delays are sources for the birth of simple and complicated dynamics. Third, the delay for collecting information on the competitors' output alone does not affect stability. PMID- 30278646 TI - Dynamics, emergent statistics, and the mean-pilot-wave potential of walking droplets. AB - A millimetric droplet may bounce and self-propel on the surface of a vertically vibrating bath, where its horizontal "walking" motion is induced by repeated impacts with its accompanying Faraday wave field. For ergodic long-time dynamics, we derive the relationship between the droplet's stationary statistical distribution and its mean wave field in a very general setting. We then focus on the case of a droplet subjected to a harmonic potential with its motion confined to a line. By analyzing the system's periodic states, we reveal a number of dynamical regimes, including those characterized by stationary bouncing droplets trapped by the harmonic potential, periodic quantized oscillations, chaotic motion and wavelike statistics, and periodic wave-trapped droplet motion that may persist even in the absence of a central force. We demonstrate that as the vibrational forcing is increased progressively, the periodic oscillations become chaotic via the Ruelle-Takens-Newhouse route. We rationalize the role of the local pilot-wave structure on the resulting droplet motion, which is akin to a random walk. We characterize the emergence of wavelike statistics influenced by the effective potential that is induced by the mean Faraday wave field. PMID- 30278647 TI - Homoclinic-doubling and homoclinic-gluing bifurcations in the Takens-Bogdanov normal form with D4 symmetry. AB - In this paper, we investigate the dynamics of a fourth-order normal form near a double Takens-Bogdanov bifurcation. The reduced system of this normal form possesses eight pairs of homoclinic orbits for certain parameter values. The nonlinear time transformation method is applied to obtain an analytical approximation of the homoclinic orbit in the perturbed system and to construct the homoclinic bifurcation curve as well. Using numerical continuation, period doubling and homoclinic-doubling cascades emanating from a codimension-2 bifurcation point are found. A codimension-2 homoclinic-gluing bifurcation point at which several homoclinic orbits concerning the origin glue together to form a new homoclinic orbit is also obtained. It is shown that in the vicinity of these bifurcation points, the system may exhibit chaos and chaotic attractors. PMID- 30278649 TI - A fractal-based approach for modeling stock price variations. AB - The recent global financial crisis has threatened the financial system with total collapse of many economic sectors with a particular penetration to world's stock markets. The large swings in the prices of international stocks or indexes have reinvigorated the debate on their mathematical modeling. The traditional approaches do not seem to be very exhaustive and satisfactory, especially when extreme events occur. We propose a fractal-based approach to model the actual prices by assuming that they follow a Multifractional Process with Random Exponent. An empirical evidence is offered that this stochastic process is able to provide an appropriate modeling of actual series in terms of goodness of fit by comparing three main stock indexes. PMID- 30278648 TI - Transition to chaos in wave memory dynamics in a harmonic well: Deterministic and noise-driven behavior. AB - A walker is the association of a sub-millimetric bouncing drop moving along with a co-evolving Faraday wave. When confined in a harmonic potential, its stable trajectories are periodic and quantised both in extension and mean angular momentum. In this article, we present the rest of the story, specifically the chaotic paths. They are chaotic and show intermittent behaviors between an unstable quantised set of attractors. First, we present the two possible situations we find experimentally. Then, we emphasise theoretically two mechanisms that lead to unstable situations. It corresponds either to noise driven chaos or low-dimensional deterministic chaos. Finally, we characterise experimentally each of these distinct situations. This article aims at presenting a comprehensive investigation of the unstable paths in order to complete the picture of walkers in a two dimensional harmonic potential. PMID- 30278650 TI - Interaction of two walkers: Perturbed vertical dynamics as a source of chaos. AB - Walkers are dual objects comprising a bouncing droplet dynamically coupled to an underlying Faraday wave at the surface of a vibrated bath. In this paper, we study the wave-mediated interaction of two walkers launched at one another, both experimentally and theoretically. Different outcomes are observed in which either the walkers scatter or they bind to each other in orbits or promenade-like motions. The outcome is highly sensitive to initial conditions, which is a signature of chaos, though the time during which perturbations are amplified is finite. The vertical bouncing dynamics, periodic for a single walker, is also strongly perturbed during the interaction, owing to the superposition of the wave contributions of each droplet. Thanks to a model based on inelastic balls coupled to the Faraday waves, we show that this perturbed vertical dynamics is the source of horizontal chaos in such a system. PMID- 30278651 TI - Dynamics of a binary mixture of non-spherical molecules: Test of hydrodynamic predictions. AB - We consider a new class of model systems to study systematically the role of molecular shape in the transport properties of dense liquids. Our model is a liquid binary mixture where both the molecules are non-spherical and characterized by a collection of parameters. Although in the real world most of the molecules are non-spherical, only a limited number of theoretical studies exist on the effects of molecular shapes and hardly any have addressed the validity of the hydrodynamic predictions of rotational and translational diffusion of these shapes in liquids. In this work, we study a model liquid consisting of a mixture of prolate and oblate (80:20 mixture) ellipsoids with interactions governed by a modified Gay-Berne potential for a particular aspect ratio (ratio of the length and diameter of the ellipsoids), at various temperature and pressure conditions. We report calculations of transport properties of this binary mixture by varying temperature over a wide range at a fixed pressure. We find that for the pressure-density conditions studied, there is no signature of any phase separation, except transitions to the crystalline phase at low temperatures and relatively low pressure (the reason we largely confined our studies to high pressure). We find that for our model binary mixture, both stick and slip hydrodynamic predictions break down in a major fashion, for both prolates and oblates and particularly so for rotation. Moreover, prolates and oblates themselves display different dynamical features in the mean square displacement and in orientational time correlation functions. PMID- 30278652 TI - Impulsive alignment of 4He-CH3I: A theoretical study. AB - We simulate the non-adiabatic laser alignment of the weakly bound 4He-CH3I complex based on a quantum mechanical wave packet calculation for a model He-CH3I interaction potential. Two different regimes are found depending on the laser intensity. At intensities typical of non-adiabatic alignment experiments, the rotational dynamics resembles that of the isolated molecule. This is attributed to the fact that after the initial prompt alignment peak the complex rapidly dissociates. The subsequent revival pattern is due to the free rotation of the molecule detached from the helium atom. It is superimposed to a flat background corresponding to ~20% of the wave packet which remains bound, containing lower rotational excitation. At lower intensities, dissociation is avoided but the rotational excitation is not high enough to provide an efficient alignment and a broad non-regular structure is observed. Besides, the interaction of the He atom with the molecule quenches any possible alignment. These interpretations are based on the calculation of different observables related to the rotational motion. We compare our findings with recent experimental and theoretical results of non-adiabatic alignment of linear molecules solvated in helium nanodroplets or weakly interacting with one helium atom.

We furthermore present the theory to calculate the stress tensors necessary for the computation of optimized cell volumes of molecular crystals and compare all results to those obtained with various density functionals and more approximate methods. Our QM:QM calculations with PBE0:PBE+D3, PBE0:PBE+MBD, and B3LYP:BLYP+D3 yield at a reduced computational cost lattice energy errors close to the ones of the parent hybrid density functional method, whereas for cell volumes, the errors of the QM:QM scheme methods are in between the generalized gradient approximation and hybrid functionals. PMID- 30278655 TI - Computation of static quantum triplet structure factors of liquid para-hydrogen. AB - The instantaneous and centroid triplet structure factors, S(3)(k1,k2) , of liquid (one-center) para-hydrogen are computed on the crystallization line for temperatures T/K <= 33. The focus is on salient equilateral and isosceles features, and the methods utilized are path integral Monte Carlo (PIMC) simulations and Ornstein-Zernike (OZ) integral equations, which involve Jackson Feenberg convolution (JF3) and other distinct closures. Long path integral simulation runs are carried out in the canonical ensemble, so as to obtain sufficiently accurate direct PI triplet results. Conclusions are drawn regarding general triplet structure features and the role and usefulness of the OZ closures. The equilateral features are studied in more detail, and one finds that (a) PIMC results point to the existence of regularity in the centroid main peak amplitudes; (b) some of the studied closures give qualitative descriptions for wave numbers below k ~ 1 A-1, but they all fail to describe the main peak amplitude regions (1.75 < k/A-1 < 2.5); and (c) JF3 plays the role of a limit closure that is valid for increasing wave numbers (k >= 2.6 A-1). In addition, representative isosceles PI features turn out to be reasonably bounded (within Deltak = 0.1 A-1) by those of some closures. PMID- 30278656 TI - The thermodynamics of a liquid-solid interface at extreme conditions: A model close-packed system up to 100 GPa. AB - The first experimental insight into the nature of the liquid-solid interface occurred with the pioneering experiments of Turnbull, which simultaneously demonstrated both that metals could be deeply undercooled (and therefore had relatively large barriers to nucleation) and that the inferred interfacial free energy gamma was linearly proportional to the enthalpy of fusion [D. Turnbull, J. Appl. Phys. 21, 1022 (1950)]. By an atomistic simulation of a model face-centered cubic system via adiabatic free energy dynamics, we extend Turnbull's result to the realm of high pressure and demonstrate that the interfacial free energy, evaluated along the melting curve, remains linear with the bulk enthalpy of fusion, even up to 100 GPa. This linear dependence of gamma on pressure is shown to be a consequence of the entropy dominating the free energy of the interface in conjunction with the fact that the entropy of fusion does not vary greatly along the melting curve for simple monoatomic metals. Based on this observation, it appears that large undercoolings in liquid metals can be achieved even at very high pressure. Therefore, nucleation rates at high pressure are expected to be non-negligible, resulting in observable solidification kinetics.

AB - Measurements of elastic differential cross sections for electron scattering from acetonitrile (CH3CN) have been performed utilizing a crossed electron-molecular beam experiment and with the relative flow method, for the incident electron energy range of 0.7 eV-30 eV and the scattering angle range of 10 degrees -130 degrees . These differential cross sections have been used to calculate the elastic integral and momentum-transfer cross sections, revealing a pi * resonance located around 3 eV. The elastic differential cross sections are compared with available theoretical models using the R-matrix method and the Schwinger multichannel method. PMID- 30278658 TI - Statistical field theory for polar fluids. AB - Using a variational field-theoretic approach, we derive a theory for polar fluids. The theory naturally accounts for the reaction field without resorting to the cavity construct and leads to a simple formula for the dielectric constant in terms of the molecular dipole moment and density. We apply our formula to calculate the dielectric constants of nonpolarizable liquid models for more than a hundred small molecules without using any adjustable parameters. Our formula predicts dielectric constants of these nonpolarizable liquid models more accurately than the Onsager theory and previous field-theoretic dielectric theories, as demonstrated by the closer agreement to the simulation results. The general theory also yields the free energy, which can describe the response of polar fluids under applied electric fields. PMID- 30278659 TI - Coarse-grained modeling of multiphase interactions at microscale. AB - The objective of this study is to develop and test a coarse-grained molecular dynamics framework to model microscale multiphase systems with different inter particle interactions and recover emerging thermodynamic and mechanical properties at the microscale. A water-vapor model and a fused silica model are developed to demonstrate the capability of our framework. The former can reproduce the water density and surface tension over a wide range of temperatures; the latter can reproduce experimental density, tensile strength, and Young's modulus of fused silica. Therefore, the deformable solid model is implemented in the proposed framework. Validations of spatial scaling methods for solid, liquid, and multiphase systems suggest that the proposed framework can be calibrated at an arbitrary microscale and used at a different length scale without recalibration. Different values of wettability for a solid-liquid-vapor system that is characterized by the contact angle can be achieved by changing the solid-liquid inter-particle potential. Thanks to these features, the proposed coarse-grained molecular dynamics framework can potentially find applications in modeling systems in which multiple phases coexist and have substantial interactions.

AB - We present Molecular Dynamics (MD) simulations of liquid-vapor surfaces, and their Intrinsic Sampling Method analysis, to get a quantitative test for the theoretical prediction of the capillary wave (CW) effects on density correlation done by Bedeaux and Weeks (BW) in 1985. The results are contrasted with Wertheim's proposal which is the first term in BW series and are complemented with a (formally defined and computational accessible) proposal for the background of non-CW fluctuations. Our conclusion is that BW theory is both accurate and needed since it may differ significantly from Wertheim's proposal. We discuss the implications for the analysis of experimental X-ray surface diffraction data and MD simulations.

AB - In this paper, real-time time-dependent density functional theory (RT-TDDFT) calculations of realistically sized nanodevices are presented. These microcanonical simulations rely on a closed boundary approach based on recent advances in the software package CP2K. The obtained results are compared to those derived from the open-boundary Non-equilibrium Green's Function (NEGF) formalism. A good agreement between the "current vs. voltage" characteristics produced by both methods is demonstrated for three representative device structures, a carbon nanotube field-effect transistor, a GeSe selector for crossbar arrays, and a conductive bridging random-access memory cell. Different approaches to extract the electrostatic contribution from the RT-TDDFT Hamiltonian and to incorporate the result into the NEGF calculations are presented.

AB - In this work, we report calculated vibrational energy levels of the methane molecule up to 10 300 cm-1. Two potential energy surfaces constructed in quite different coordinate systems with different analytical representations are employed in order to evaluate the uncertainty of vibrational predictions. To calculate methane energy levels, we used two independent techniques of the variational method. One method uses an exact kinetic energy operator in internal curvilinear coordinates. Another one uses an expansion of Eckart-Watson nuclear motion Hamiltonian in rectilinear normal coordinates. In the Icosad range (up to five vibrational quanta bands-below 7800 cm-1), the RMS standard deviations between calculated and observed energy levels were 0.22 cm-1 and 0.41 cm-1 for these two quite different approaches. For experimentally well-known 3v3 sub levels, the calculation accuracy is estimated to be ~1 cm-1. In the Triacontad range (7660-9188 cm-1), the average error of the calculation is about 0.5 cm-1. The accuracy and convergence issues for higher energy ranges are discussed.

AB - Dielectric relaxation (DR) measurements in the frequency window 0.2 <= nu(GHz) <= 50 for deep eutectic solvents (DESs) made of acetamide (CH3CONH2) and urea (NH2CONH2) with the general composition, [f CH3CONH2 + (1 - f) NH2CONH2] at f = 0.6 and 0.7, reveal three distinct relaxation time scales-tau1 ~ 120 ps, tau2 ~ 40 ps, and tau3 ~ 5 ps. Qualitatively similar time scales have been observed for DR of neat molten urea, whereas the reported DR for neat molten acetamide in the same frequency window reflects two relaxation processes with no trace of ~100 ps time scale. This slowest DR time scale (tau1) resembles closely to the long-time constant of the simulated structural H-bond relaxation (CHB(t)) involving urea pairs. Similarity in activation energies estimated from the temperature dependent DR measurements (335 <= T/K <= 363) and structural H-bond relaxations indicates that the structural H-bond relaxation overwhelmingly dominates the slowest DR relaxation in these DESs. Simulated collective reorientational correlation functions (C l (t)), on the other hand, suggest that the second slower time scale (~40 ps) derives contributions from both the single particle orientation dynamics and structural H-bond relaxation, leaving no role for hydrodynamic molecular rotations. The sub-10 ps DR time scale has been found to be connected to the fast reorientation dynamics of the component molecules (acetamide or urea). Fractional viscosity dependence for the longest DR times, tauDR?eta/Tp , has been observed for these DESs with the fraction power p = 0.7. Subsequently, the temporal heterogeneity aspects of these media have been investigated by examining the simulated particle motion characteristics and substantiated by estimating the dynamically correlated time scales and length-scales through simulations of four point susceptibilities and density correlations. These estimated dynamical time scales and length-scales assist in explaining the different inferences regarding solution heterogeneity drawn from different measurements on these DESs.

AB - The aqueous solvation structure of the Na+ ion is studied both by molecular dynamics (MD) simulations and K-edge X-ray absorption near edge spectroscopy (XANES). We present a systematic study contrasting the differences in the predicted XANES spectra, using molecular configurations generated from classical and quantum MD. Using a set of suitable order parameters, we elucidate how the spectroscopic features are influenced by the local solvation structure around the Na+ ion. Our findings suggest that XANES is sensitive to fluctuations between the first and second solvation shells and can distinguish between classical and quantum interaction representations used to generate molecular ensembles. PMID- 30278665 TI - Long-range dispersion C6 coefficient for SF6 dimer: Experimental and theoretical study. AB - The long-range dispersion C6 coefficient for the SF6 dimer is experimentally measured using a technique that uses the expansion of a supersonic pulse jet into a vacuum. A dynamic model of the jet enables us to correlate the position of the maximal peak in the time-of-flight spectrum with the initial conditions of the experiment and the parameters of the intermolecular interaction potential. Due to the low temperature of the jet target, the C6 coefficient can be extracted directly from the experimental results. Theoretical calculation of the C6 dispersion coefficient is also performed by using linearly approximated explicitly correlated coupled-cluster singles and doubles (CCSD(F12)) method with the subsequent utilization of the Casimir-Polder formula. Good agreement of experimental and theoretical results confirms the reliability of results. PMID- 30278666 TI - Effects of thermostatting in molecular dynamics on anharmonic properties of crystals: Application to fcc Al at high pressure and temperature. AB - The precision and accuracy of the anharmonic energy calculated in the canonical (NVT) ensemble using three different thermostats (viz., Andersen, Langevin, and Nose-Hoover) along with no thermostat (i.e., microcanonical, NVE) are compared via application to aluminum crystals at ~100 GPa for temperatures up to melting (4000 K) using ab initio molecular dynamics (AIMD) simulation. In addition to the role of the thermostat, the effect of using either conventional or the recently introduced harmonically mapped averaging (HMA) method is considered. The effect of AIMD time-step size Deltat on the ensemble averages gauges accuracy, while for a given Deltat, the stochastic uncertainty (computed using block averaging) provides the metric for precision. We identify the rate of convergence of block averages (with respect to block size) as an important issue in this context, as it imposes a minimum simulation length required to achieve reliable statistics, and it differs considerably among the methods. We observe that HMA with a Langevin thermostat in an NVT simulation shows the best performance, from the point of view of accuracy, precision, and simulation length. In addition, we introduce a novel HMA-based ensemble average for the temperature. In application to NVE simulations, the new formulation exhibits much smaller fluctuations compared to the conventional kinetic-energy approach; however, it provides only marginal improvement in uncertainty due to strong negative correlations exhibited by the conventional form (which acts to reduce its uncertainty but also slows convergence of the block averages). PMID- 30278667 TI - Experimental and theoretical investigations on the optical and electrochemical properties of pi-conjugated donor-acceptor-donor (DAD) compounds toward a universal model. AB - A series of nine (9) donor-acceptor-donor (DAD) pi-conjugated small molecules were synthesized via palladium catalyzed Stille aromatic cross-coupling reactions by the combination of six (6) heterocycle building blocks (thiophene, furan, thiazole, 2,1,3-benzothiadiazole, 2,1,3-pyridinothiadiazole, thienothiadiazole) acting as electron donating (thiazole, furan, thiophene) and electron deficient (benzothiadiazole, pyridinethiadiazole, thienothiadiazole) units. These model compounds enable determining the correspondence between the theoretical and experimental optical and electrochemical properties for the first time, via Density Functional Theory (DFT), time-dependent DFT, UV-Vis spectroscopy, and cyclic voltammetry, accordingly. The obtained theoretical models can be utilized for the design and synthesis of new DAD structures with precise optical bandgaps, absorption maxima, and energy levels suitable for different optoelectronic applications. PMID- 30278668 TI - Thermal behavior, structure, dynamic properties of aqueous glycine solutions confined in mesoporous silica MCM-41 investigated by x-ray diffraction and quasi elastic neutron scattering. AB - Differential scanning calorimetry, X-ray diffraction, and quasi-elastic neutron scattering (QENS) measurements of aqueous glycine solutions confined in mesoporous silica (MCM-41) were performed at different glycine concentrations, pH, and loading ratio (=mass of glycine solution/mass of dry MCM-41) in the temperature range from 305 to 180 K to discuss the confinement effect on the thermal behavior, the structure, and the dynamic properties of the solutions. The freezing points of the confined glycine solutions decreased, compared with those of the bulk solutions. The corresponding exothermic peak due to ice formation became broader with an increase in the glycine concentration. By subtracting X ray diffraction patterns of dry MCM-41 from those of glycine solution-loaded MCM 41, information about the structure of the confined glycine solutions was obtained. The radial distribution functions of the confined glycine solutions showed that the peaks assigned to the interaction between glycine molecules and the surface silanol (Si-OH) groups of MCM-41 at pH = 5 were observed, in contrast to the case at pH = 2. The QENS data on H/D substituted aqueous glycine solutions gave the translational diffusion coefficients and the residence time of glycine and water molecules confined in MCM-41 individually. The activation energy of the diffusion coefficient of a glycine molecule at pH = 5 was larger than that at pH = 2. These results imply that glycine molecules locate near the pore surface of MCM-41 due to the formation of hydrogen bonding between glycine molecules and the silanol group of the MCM-41 wall at pH = 5. PMID- 30278669 TI - Communication: State-to-state inelastic scattering of interstellar O2 with H2. AB - Molecular oxygen (O2) is predicted to be a major reservoir of elemental oxygen in dense interstellar molecular clouds. However, the abundance of O2 derived from astronomical observations is much lower than expected. Solving the discrepancies between models and observations requires a review of the chemistry and collisional excitation of O2 in space. In particular, O2-H2 collisions are crucial to derive O2 abundance in space from the interstellar spectra. A crossed molecular beam experiment to probe the rotational excitation of O2 due to H2 collisions at energies of 650 cm-1 is reported. Velocity map imaging was combined with state-selective detection of O2( X3Sigmag- ) by (2 + 1) resonance-enhanced multiphoton ionization. The obtained raw O2+ images were corrected from density to flux and the differential cross sections (DCSs) were then extracted. Exact quantum mechanical calculations were also performed. Very good agreement between experimental and theoretical DCSs was found. The agreement demonstrates our ability to determine inelastic processes between O2 molecules and H2 both theoretically and experimentally and that the excitation of O2 in the interstellar medium can be correctly modeled. Consequences on the astrophysical modeling are briefly evaluated. PMID- 30278670 TI - Optimized symmetry functions for machine-learning interatomic potentials of multicomponent systems. AB - Current machine-learning methods to reproduce ab initio potential energy landscapes suffer from an unfavorable computational scaling with respect to the number of chemical species. In this work, we propose a new approach by using optimized symmetry functions to explore similarities of structures in multicomponent systems in order to yield linear complexity. We combine these symmetry functions with the charge equilibration via neural network technique, a reliable artificial neural network potential for ionic materials, and apply this method to study alkali-halide materials MX with 6 chemical species (M = {Li, Na, K} and X = {F, Cl, Br}). Our results show that our approach provides good agreement both with experimental and DFT reference data of many physical and structural properties for any chemical combination. PMID- 30278671 TI - Dispersion in two-dimensional periodic channels with discontinuous profiles. AB - The effective diffusivity of Brownian tracer particles confined in periodic micro channels is smaller than the microscopic diffusivity due to entropic trapping. Here, we study diffusion in two-dimensional periodic channels whose cross section presents singular points, such as abrupt changes of radius or the presence of thin walls, with openings, delimiting periodic compartments composing the channel. Dispersion in such systems is analyzed using the Fick-Jacobs (FJ) approximation. This approximation assumes a much faster equilibration in the lateral than in the axial direction, along which the dispersion is measured. If the characteristic width a of the channel is much smaller than the period L of the channel, i.e., epsilon = a/L is small, this assumption is clearly valid for Brownian particles. For discontinuous channels, the FJ approximation is only valid at the lowest order in epsilon and provides a rough, though on occasions rather accurate, estimate of the effective diffusivity. Here we provide formulas for the effective diffusivity in discontinuous channels that are asymptotically exact at the next-to-leading order in epsilon. Each discontinuity leads to a reduction of the effective diffusivity. We show that our theory is consistent with the picture of effective trapping rates associated with each discontinuity, for which our theory provides explicit and asymptotically exact formulas. Our analytical predictions are confirmed by numerical analysis. Our results provide a precise quantification of the kinetic entropic barriers associated with profile singularities. PMID- 30278672 TI - Parent bending effects on nonadiabatic transition dynamics: Isotopomer-resolved imaging of photodissociation of CF3Br at two source temperatures. AB - Nonadiabatic transition between electronic states plays a critical role in the photodissociation of the CX3Y (X = H and F; Y = Cl, Br, and I) system, and the transition probability was considered to be closely related to the X-C-Y bending motion. Hereby the effect of F-C-Br bending vibration on the nonadiabatic transition dynamics is studied by time-sliced ion velocity imaging of Br(2P1/2,3/2) isotopomers produced from the photodissociation of title molecules at two source temperatures, 298 K and 473 K, respectively. At the photolysis wavelength 234 nm, the anisotropy parameter (beta) of the Br(2P3/2) products decreases from 1.3 at 298 K to 0.9 at 473 K, while the beta of Br(2P1/2) remains at almost 2 at two temperatures, indicating the significant effect of bending excitation on the ground channel. Two nonadiabatic dissociation pathways are suggested in the Br(2P3/2) channel. One of them is the parallel excitation from the ground state to the 3 Q 0 state in C3V symmetry, and then transition to the 1 Q 1 state via conical intersection, and the other is the perpendicular excitation to the 3A' state in Cs symmetry and then decomposition along this state in the presence of the avoided crossing between 3A' and 4A' states. Closely related to the F-C-Br bending vibration of CF3Br is the latter transition. PMID- 30278673 TI - Influence of solvent quality on conformations of crowded polymers. AB - The structure and function of polymers in confined environments, e.g., biopolymers in the cytoplasm of a cell, are strongly affected by macromolecular crowding. To explore the influence of solvent quality on conformations of crowded polymers, we model polymers as penetrable ellipsoids, whose shape fluctuations are governed by the statistics of self-avoiding walks, appropriate for a polymer in a good solvent. Within this coarse-grained model, we perform Monte Carlo simulations of mixtures of polymers and hard-nanosphere crowders, including trial changes in polymer size and shape. Penetration of polymers by crowders is incorporated via a free energy cost predicted by polymer field theory. To analyze the impact of crowding on polymer conformations in different solvents, we compute the average polymer shape distributions, radius of gyration, volume, and asphericity over ranges of the polymer-to-crowder size ratio and crowder volume fraction. The simulation results are accurately predicted by a free-volume theory of polymer crowding. Comparison of results for polymers in good and theta solvents indicates that excluded-volume interactions between polymer segments significantly affect crowding, especially in the limit of crowders much smaller than polymers. Our approach may help to motivate future experimental studies of polymers in crowded environments, with possible relevance for drug delivery and gene therapy. PMID- 30278674 TI - Efficient evaluation of the geometrical first derivatives of three-center Coulomb integrals. AB - The calculation of the geometrical derivatives of three-center electron repulsion integrals (ERIs) over contracted spherical harmonic Gaussians has been optimized. We compared various methods based on the Obara-Saika, McMurchie-Davidson, Gill Head-Gordon-Pople, and Rys polynomial algorithms using Cartesian, Hermite, and mixed Gaussian integrals for each scheme. The latter ERIs contain both Hermite and Cartesian Gaussians, and they combine the advantageous properties of both types of basis functions. Furthermore, prescreening of the ERI derivatives is discussed, and an efficient approximation of the Cauchy-Schwarz bound for first derivatives is presented. Based on the estimated operation counts, the most promising schemes were implemented by automated code generation, and their relative performances were evaluated. We analyzed the benefits of computing all of the derivatives of a shell triplet simultaneously compared to calculating them just for one degree of freedom at a time, and it was found that the former scheme offers a speedup close to an order of magnitude with a triple-zeta quality basis when appropriate prescreening is applied. In these cases, the Obara-Saika method with Cartesian Gaussians proved to be the best approach, but when derivatives for one degree of freedom are required at a time the mixed Gaussian Obara-Saika and Gill-Head-Gordon-Pople algorithms are predicted to be the best performing ones. PMID- 30278675 TI - The role of chain-stiffness in lattice protein models: A replica-exchange Wang Landau study. AB - Using Monte Carlo simulations, we investigate simple, physically motivated extensions to the hydrophobic-polar lattice protein model for the small (46 amino acid) protein Crambin. We use two-dimensional replica-exchange Wang-Landau sampling to study the effects of a bond angle stiffness parameter on the folding and uncover a new step in the collapse process for particular values of this stiffness parameter. A physical interpretation of the folding is developed by analysis of changes in structural quantities, and the free energy landscape is explored. For these special values of stiffness, we find non-degenerate ground states, a property that is consistent with behavior of real proteins, and we use these unique ground states to elucidate the formation of native contacts during the folding process. Through this analysis, we conclude that chain-stiffness is particularly influential in the low energy, low temperature regime of the folding process once the lattice protein has partially collapsed. PMID- 30278676 TI - Thermal conductivity of normal and deuterated water, crystalline ice, and amorphous ices. AB - The effect of deuteration on the thermal conductivity kappa of water, crystalline ice, and amorphous ices was studied using the pressure induced amorphization of hexagonal ice, ice Ih, to obtain the deuterated, D2O, forms of low-density amorphous (LDA), high-density amorphous (HDA), and very-high density amorphous (VHDA) ices. Upon deuteration, kappa of ice Ih decreases between 3% and 4% in the 100-270 K range at ambient pressure, but the effect diminishes on densification at 130 K and vanishes just prior to amorphization near 0.8 GPa. The unusual negative value of the isothermal density rho dependence of kappa for ice Ih, g = (d ln kappa/d ln rho) T = -4.4, is less so for deuterated ice: g = -3.8. In the case of the amorphous ices and liquid water, kappa of water decreases by 3.5% upon deuteration at ambient conditions, whereas kappa of HDA and VHDA ices instead increases by up to 5% for pressures up to 1.2 GPa at 130 K, despite HDA's and VHDA's structural similarities with water. The results are consistent with significant heat transport by librational modes in amorphous ices as well as water, and that deuteration increases phonon-phonon scattering in crystalline ice. Heat transport by librational modes is more pronounced in D2O than in H2O at low temperatures due to a deuteration-induced redshift of librational mode frequencies. Moreover, the results show that kappa of deuterated LDA ice is 4% larger than that of normal LDA at 130 K, and both forms display an unusual temperature dependence of kappa, which is reminiscent of that for crystals (kappa ~ T -1), and a unique negative pressure dependence of kappa, which likely is linked to local-order structural similarities to ice Ih.

AB - The Finnish Meteorological Institute-Aerosol Cloud Interaction Tube (FMI-ACIT) is a multi-purpose instrument for investigating atmospherically relevant interactions between aerosol particles and water vapor under defined laboratory conditions. This work introduces an experimental setup of FMI-ACIT for investigation of the aerosol activation and the droplet growth under supersaturated conditions. Several simulations and experimental tests were conducted to find out what the proper operational parameters are. To verify the ability of FMI-ACIT to perform as a cloud condensation nuclei (CCN) counter, activation experiments were executed using size selected ammonium sulfate [(NH4)2SO4] particles in the size range of 10-300 nm. Supersaturations from 0.18% to 1.25% were tested by experiments with different temperature gradients. Those showed that FMI-ACIT can effectively measure CCN in this range. Measured droplet size distributions at supersaturations 0.18% and 1.25% are in good agreement with those determined by a droplet growth model. PMID- 30278678 TI - An atomistic model for the charge distribution in layered MoS2. AB - We present an atomistic model for predicting the distribution of doping electric charges in layered molybdenum disulfide (MoS2). This model mimics the charge around each ion as a net Gaussian-spatially distributed charge plus an induced dipole, and is able to predict the distribution of doping charges in layered MoS2 in a self-consistent scheme. The profiles of doping charges in monolayer MoS2 flakes computed by this charge-dipole model are in good agreement with those obtained by density-functional-theory calculations. Using this model, we quantitatively predict the charge enhancement in MoS2 monolayer nanoribbons, with which strong ionic charge-localization effects are shown. PMID- 30278679 TI - Non-equilibrium molecular-dynamics study of electromagnetic-field-induced propane hydrate dissociation. AB - Non-equilibrium molecular-dynamics simulations have been performed for dissolution of planar propane-hydrate/water interfaces in externally-applied electromagnetic (e/m) fields in the microwave to far infrared range (~2.45-200 GHz) at electric-field intensities up to 2.0 V/nm and at roughly 20 K over/under temperatures vis-a-vis the zero-field propane-hydrate melting point. Upon e/m field application, there is a field-frequency threshold above which the dissociation rate drops significantly, with a plateau therein for larger frequencies. It was found that higher intensity and lower frequency facilitates dissociation. Except in the presence of a thermal driving-force, the 10 GHz frequency shows more substantial rate-enhancement effect vis-a-vis static electric fields or, indeed, lower-frequency e/m fields. PMID- 30278680 TI - Crucial role of fragmented and isolated defects in persistent relaxation of deeply supercooled water. AB - Properties of water have been well elucidated for temperatures above ~230 K and yet mysteries remain in the deeply supercooled region. By performing extensive molecular dynamics simulations on this supercooled region, we find that structural and dynamical instabilities are hidden in the experimentally inaccessible region between 235 K and 150 K. We find a hitherto undiscovered fragmentation from 220 K to 190 K, which is the breakup of large clusters consisting of molecules with a locally distorted tetrahedral structure into small pieces with one or two isolated defects. The fragmentation leads to considerable changes in the relaxation dynamics of water. We reveal a crucial role of specific three-coordinated defects in slow but persistent structural relaxation. The presence of relaxation due to these specific defects makes the water glass transition temperature T g (=136 K) extremely low and explains why the T g of water is ~1/2 of the melting temperature T m, much lower than the commonly obeyed 2/3 rule of T g/T m. PMID- 30278681 TI - Non-equilibrium x-ray spectroscopy using direct quantum dynamics. AB - Advances in experimental methodology aligned with technological developments, such as 3rd generation light sources, X-ray Free Electron Lasers, and High Harmonic Generation, have led to a paradigm shift in the capability of X-ray spectroscopy to deliver high temporal and spectral resolution on an extremely broad range of samples in a wide array of different environments. Importantly, the complex nature and high information content of this class of techniques mean that detailed theoretical studies are often essential to provide a firm link between the spectroscopic observables and the underlying molecular structure and dynamics. In this paper, we present approaches for simulating dynamical processes in X-ray spectroscopy based upon on-the-fly quantum dynamics with a Gaussian basis set. We show that it is possible to provide a fully quantum description of X-ray spectra without the need of precomputing highly multidimensional potential energy surfaces. It is applied to study two different dynamical situations, namely, the core-hole lifetime dynamics of the water monomer and the dissociation of CF4+ recently studied using pump-probe X-ray spectroscopy. Our results compare favourably to previous experiments, while reducing the computational effort, providing the scope to apply them to larger systems. PMID- 30278682 TI - Chemical hardness: Temperature dependent definitions and reactivity principles. AB - In this brief report, we show that the three different chemical hardness definitions developed in the framework of the temperature-dependent density functional theory-namely, the electronic, the thermodynamic, and the Helmholtz hardnesses-imply both the hard and soft acids and bases (HSAB) principle and the maximum hardness (MH) principle. These hardnesses are identified as the second derivative of a thermodynamic state function and avoid the somewhat arbitrary approach, based on the parabolic interpolation of the energy versus electron number, that is normally used to justify these principles. This not only leads to a more mathematically sound justification of the HSAB and MH principles in the low-temperature limit but also establishes that the HSAB and the MH principles hold at any temperature of chemical relevance. PMID- 30278683 TI - A coherent derivation of the Ewald summation for arbitrary orders of multipoles: The self-terms. AB - In this work, we provide the mathematical elements we think essential for a proper understanding of the calculus of the electrostatic energy of point multipoles of arbitrary order under periodic boundary conditions. The emphasis is put on the expressions of the so-called self-parts of the Ewald summation where different expressions can be found in the literature. Indeed, such expressions are of prime importance in the context of new generation polarizable force field where the self-field appears in the polarization equations. We provide a general framework, where the idea of the Ewald splitting is applied to the electric potential and, subsequently, all other quantities such as the electric field, the energy, and the forces are derived consistently thereof. Mathematical well posedness is shown for all these contributions for any order of multipolar distribution. PMID- 30278684 TI - A new type of ionizer for charge-exchange particle analyzer. AB - The application of effective methods of charge-exchange neutral particle diagnostics to determine ion temperatures of plasmas in modern plasma installations is of great practical interest. In this paper, we propose a new type of ionizer based on ionization of neutral charge-exchange particles reflecting from metallic surfaces. A set of Ta plates is used as a reflecting surface converter. The experimental results of using the proposed ionizer on the T-10 tokamak installation are presented. The obtained ion temperature is compared with temperatures derived by other methods for ohmic plasma heating. It is shown that the determined ion temperature has an error of 10% and agrees well with values calculated by the Artsimovich formula and obtained by the active Charge eXchange Recombination Spectroscopy. The proposed analyzer for ion temperature determination has an enhanced sensitivity in comparison with other analyzers.

AB - Time-resolved technique of X-ray diffraction curve measurement was implemented at a laboratory X-ray source using a high-speed data acquisition system. The time resolution of up to 100 us was achieved via this X-ray diffractometry technique in the experiment of rocking curve dynamics measurement in a piezoelectric lanthanum-gallium silicate crystal under the influence of high voltage periodic pulsed electric field with an amplitude of 3.08 kV/mm corresponding to the pre breakdown state. This perturbation caused a quick angular shift of the rocking curve caused by crystal lattice deformation due to the piezoelectric effect. The absence of the diffraction curve broadening effect was shown as well as the absence of the other significant relaxation-like variations of the curve parameters which are inherent for the migration of charge carriers (ions or vacancies) under the external electric field.

AB - The nascent suite of single-crystal neutron diffractometers at the Oak Ridge National Laboratory has no equal at any other neutron scattering facility worldwide and offers the potential to re-assert single-crystal diffraction using neutrons as a significant tool to study nuclear and magnetic structures of small unit cell crystals, nuclear structures of macromolecules, and diffuse scattering. Signature applications and features of single-crystal neutron diffraction are high resolution nuclear structure analysis, magnetic structure and spin density determinations, contrast variation (particularly D2O/H2O) for nuclear structural studies, lack of radiation damage when using crystals of biological molecules such as proteins, and the fidelity to measure nuclear and magnetic diffuse scattering with elastic discrimination.

AB - We describe the design, fabrication, and operation of a novel surface-electrode Paul trap that produces a radio-frequency-null along the axis perpendicular to the trap surface. This arrangement enables control of the vertical trapping potential and consequentially the ion-electrode distance via dc-electrodes only. We demonstrate the confinement of single 40Ca+ ions at heights between 50 MUm and 300 MUm above planar copper-coated aluminum electrodes. Laser-cooling and coherent operations are performed on both the planar and vertical motional modes. This architecture provides a platform for precision electric-field noise detection and trapping of vertical ion strings without excess micromotion and may have applications for scalable quantum computers with surface ion traps.

AB - We report on the design and construction of a versatile setup for experiments with ultracold lithium (Li) gases. We discuss our methods to prepare an atomic beam and laser cool it in a Zeeman slower and a subsequent magneto-optical trap, which rely on established methods. We focus on our laser system based on a stable interference-filter-stabilized, linear-extended-cavity diode laser, so far unreported for lithium wavelengths. Moreover, we describe our optical setup to combine various laser frequencies for cooling, manipulation, and detection of Li atoms. We characterize the performance of our system preparing degenerate samples of Li atoms via forced evaporation in a hybrid crossed-beam optical-dipole trap plus confining magnetic trap. Our apparatus allows one to produce quantum gases of N ~ 105...106 fermionic lithium-6 atoms at nanokelvin temperatures in cycle times below 10 s. Our optical system is particularly suited to study the dynamics of fermionic superfluids in engineered optical potentials.

AB - We present the design and capabilities of a high temperature gas flow environment for neutron diffraction and pair distribution function studies available at the Nanoscale Ordered Materials Diffractometer instrument at the Spallation Neutron Source. Design considerations for successful total scattering studies are discussed, and guidance for planning experiments, preparing samples, and correcting and reducing data is defined. The new capabilities are demonstrated with an in situ decomposition study of a battery electrode material under inert gas flow and an in operando carbonation/decarbonation experiment under reactive gas flow. This capability will aid in identifying and quantifying the atomistic configurations of chemically reactive species and their influence on underlying crystal structures. Furthermore, studies of reaction kinetics and growth pathways in a wide variety of functional materials can be performed across a range of length scales spanning the atomic to the nanoscale. PMID- 30278691 TI - A new method of out-of-focus millimeter wave imaging in fusion plasma diagnostics using Bessel beams. AB - Electron cyclotron emission imaging (ECEI) and microwave imaging reflectometry diagnostics have been employed on a number of magnetic fusion plasma confinement devices. The common approach is based on a Gaussian beam assumption, which generates good spatial resolution (centimeter level). However, the radial focal depth is limited by the poloidal resolution, which is comparable with the Rayleigh length (~150 mm). By contrast, a new Bessel beam approach has been developed and demonstrated to generate much longer focal depth with the property of propagation stability. To test the new approach, the DIII-D tokamak LCP ECEI optics have been re-designed to support a Bessel beam approach based on an axicon lens. The achievable radial coverage can exceed that of the current Gaussian approach by 3*. The imaging result is discussed in this paper based on the simulation analysis and laboratory testing result. PMID- 30278692 TI - Parallel 2D FFT implementation on FPGA suitable for real-time MR image processing. AB - We report the design and implementation of a parallel two-dimensional fast Fourier transform (2D FFT) algorithm on a Field Programmable Gate Array (FPGA) for real-time MR image processing. Although a number of architectures of 2D FFT hardware processors have been reported, these generic processors or IP cores are not always effective for processing MRI data. The key feature of our design is that our processors are customized solely for real-time MRI applications. We demonstrate that by considering the unique features of real-time MRI data streams, we were able to develop and implement the 2D FFT processors that are resource-efficient and flexible enough to handle both regular and irregular data. Using a data-driven approach, we were able to simplify the inter-processor data communication while maintaining data synchronization without a synchronous clock signal bus and complex interconnection network. We experimentally verified our designs by processing multi-slice image data sets with 128 * 128 and 256 * 256 in plane resolution. The results demonstrate the effectiveness of our 2D FFT processors and show that image reconstruction can be accelerated in proportion to the parallel processing factor. We achieved image-reconstruction processing rates up to 3000 and 800 slices per second for images with 128 * 128 and 256 * 256 in plane resolution, respectively. The results also indicate that the image reconstruction acceleration is primarily limited by the speed of the data transfer between the FPGA device and external sensors.

AB - Here, we report a simple technique that uses mesoporous SnO2 to monitor the water quality and degrade the hazardous organic pollutants simultaneously. The technique generates hydroxyl radicals and a voltage that is hindered by the presence of hazardous organic pollutants. Pollutant as low as 1 ppb concentration level can easily be detected. The developed system not only monitors the water quality but also is capable of degrading hazardous dyes (organic pollutants) through its self-power, not relying on any external stimuli such as light, heat, radiation, and current. A simple digital laboratory multimeter is shown to be useful for the overall study. Overall, the study indicates that spectrophotometer generally used to monitor the dye concentration can be avoided. PMID- 30278694 TI - Time-of-flight neutron total scattering with applied electric fields: Ex situ and in situ studies of ferroelectric materials. AB - Characterizing the structural response of functional materials (e.g., piezoelectrics and ferroelectrics) to electric fields is key for the creation of structure-property relationships. Here, we present a new sample environment and data reduction routines which allow the measurement of time-of-flight neutron total scattering during the in situ or ex situ application of high voltage (<10 kV) to a sample. Instead of utilizing the entire detector space of the diffractometer, only selected regions of detector pixels with scattering at the desired angle to the sample electric field are interrogated, which allows the generation of orientation-dependent reciprocal space patterns and real-space pair distribution functions (PDFs). We demonstrate the method using the relaxor ferroelectric Na1/2Bi1/2TiO3 and observe lattice expansion parallel and contraction perpendicular to the electric field for both in situ and ex situ experiments, revealing the irreversible nature of the local scale structural changes to this composition. Additionally, changes in the distributions of nearest neighbor metal-oxygen bond lengths are observed, which have been difficult to observe in previously measured analogous orientation-dependent X-ray PDFs. Considerations related to sample positioning and background subtraction are discussed, and future research directions are suggested. PMID- 30278696 TI - Photometrics of ultrafast and fast broadband electronic transient absorption spectroscopy: State of the art. AB - The physical limits of the photometric resolution in broadband electronic transient absorption spectroscopy are discussed together with solutions for how to reach these limits in practice. In the first part, quantitative expressions for the noise contributions to the transient absorption signal are derived and experimentally tested. Experimental approaches described in the literature are discussed and compared on this basis. Guide-lines for designing a setup are established. In the second part, a method for obtaining nearly shot-noise limited kinetics with photometric resolution of the order of 100 MUOD in overall measurement times of a few minutes from femtosecond to microsecond time scale is presented. The results are discussed in view of other experiments of step-scan type which are subject to a background or to correlated noise. Finally, detailed information is provided on how to obtain transient absorption spectra where counting statistics are the sole source of noise. A method for how to suppress outliers without introducing bias is discussed. An application example is given to demonstrate the achievable signal-to-noise level and the fast acquisition time. PMID- 30278695 TI - Calibration and cross-laboratory implementation of scintillating screens for electron bunch charge determination. AB - We revise the calibration of scintillating screens commonly used to detect relativistic electron beams with low average current, e.g., from laser-plasma accelerators, based on new and expanded measurements that include higher charge density and different types of screens than previous work [Buck et al., Rev. Sci. Instrum. 81, 033301 (2010)]. Electron peak charge densities up to 10 nC/mm2 were provided by focused picosecond-long electron beams delivered by the Electron Linac for beams with high Brilliance and low Emittance (ELBE) at the Helmholtz Zentrum Dresden-Rossendorf. At low charge densities, a linear scintillation response was found, followed by the onset of saturation in the range of nC/mm2. The absolute calibration factor (photons/sr/pC) in this linear regime was measured to be almost a factor of 2 lower than that reported by Buck et al. retrospectively implying a higher charge in the charge measurements performed with the former calibration. A good agreement was found with the results provided by Glinec et al. [Rev. Sci. Instrum. 77, 103301 (2006)]. Furthermore long-term irradiation tests with an integrated dose of approximately 50 nC/mm2 indicate a significant decrease of the scintillation efficiency over time. Finally, in order to enable the transfer of the absolute calibration between laboratories, a new constant reference light source has been developed.

PMID- 30278698 TI - AGES: Automated Gas Environment System for in situ neutron powder diffraction. AB - High fluxes available at modern neutron and synchrotron sources have opened up a wide variety of in situ and operando studies of real processes using scattering techniques. This has allowed the user community to follow chemistry in the beam, which often requires high temperatures, gas flow, etc. In this paper, we describe an integrated gas handling system for the general-purpose powder diffraction beamline Powgen at the Spallation Neutron Source. The Automated Gas Environment System (AGES) allows control of both gas flow and temperature (room temperature to 850 degrees C), while measuring the partial pressure of oxygen and following the effluent gas by mass spectrometry, concurrent with neutron powder diffraction, in order to follow the structural evolution of materials under these conditions. The versatility of AGES is illustrated by two examples of experiments conducted with the system. In solid oxide fuel cell electrode materials, oxygen transport pathways in double perovskites PrBaCo2O5+delta and NdBaCo2O5+delta were elucidated by neutron diffraction measurements under atmosphere with oxygen partial pressures (pO2) of 10-1 to 10-4 (achieved using mixtures of nitrogen and oxygen) and temperatures from 575 to 850 degrees C. In another example, the potential oxygen storage material La1-xSrxFeO3 was measured under alternating flows of 15% CH4 in N2 and air (20% O2 in N2) at temperatures from 135 to 835 degrees C. From the oxygen stoichiometry, the optimal composition for oxygen storage was determined. PMID- 30278699 TI - Invited Article: Advances in tunable laser-based radiometric calibration applications at the National Institute of Standards and Technology, USA. AB - Recent developments at the National Institute of Standards and Technology's facility for Spectral Irradiance and Radiance responsivity Calibrations using Uniform Sources (SIRCUS) are presented. The facility is predicated on the use of broadly tunable narrow-band lasers as light sources in two key radiometric calibration applications. In the first application, the tunable lasers are used to calibrate the spectral power responsivities of primary standard detectors against an absolute cryogenic radiometer (ACR). The second function is to calibrate the absolute radiance and irradiance responsivities of detectors with uniform light sources, typically generated by coupling the laser light into integrating spheres. The radiant flux from the uniform sources is determined by the ACR-calibrated primary standard detectors. Together these sources and detectors are used to transfer radiometric scales to a variety of optical instruments with low uncertainties. We describe methods for obtaining the stable, uniform light sources required for low uncertainty measurements along with advances in laser sources that facilitate tuning over broader wavelength ranges. Example applications include the development of a detector-based thermodynamic temperature scale, the calibration and characterization of spectrographs, and the use of a traveling version of SIRCUS (T-SIRCUS) to calibrate large aperture Earth observing instruments and astronomical telescopes.

AB - High-space-resolving information of hotspot electron temperature is a foundation for further research on physical processes of implosion in inertial confinement fusion. This work proposed a novel high-space-resolving electron temperature detector, which is based on the bremsstrahlung radiation mechanism of the implosion hotspot and uses two-channel Kirkpatrick-Baez microscopes. In this novel detector, an optical quasi-coaxis method was used to eliminate the strong impact of the view field difference on the high space resolution and correctness of the electron temperature diagnosis, and a compound KB microscope method was proposed to reduce the number of spherical reflectors and save space. PMID- 30278701 TI - Note: A compact low-vibration high-performance optical shutter for precision measurement experiments. AB - The optical shutter is an important component for atom-interferometry-based precision measurements. To decrease its vibration noise and improve its performance, we present a compact design with a direct current motor and a photodetector inserted in a compact aluminum structure. The photodetector in the blade is driven by the motor to move either in or out of the way of the laser beam. This design can suppress laser intensity fluctuation down to 0.26% over 6 h in the method of sample and hold proportional-integral-derivative feedback. It is also quiet via an electrical braking process which not only reduces its vibration noise by an order of magnitude but also quickens and stabilizes its switching performance. The shutter has a switching time of 0.8 ms and an activation delay of 8 ms with low jitters. Besides, the shutter can work for over ten million cycles normally and reliably. PMID- 30278702 TI - An ultrahigh vacuum apparatus for H atom scattering from surfaces. AB - We present an apparatus to study inelastic H or D atom scattering from surfaces under ultra-high vacuum conditions. The apparatus provides high resolution information on scattering energy and angular distributions by combining a photolysis-based atom source with Rydberg atom tagging time-of-flight. Using hydrogen halides as precursors, H and D atom beams can be formed with energies from 500 meV up to 7 eV, with an energy spread of down to 2 meV and an intensity of up to 108 atoms per pulse. A six-axis manipulator holds the sample and allows variation of both polar and azimuthal incidence angles. Surface temperature can be varied from 45 K up to 1500 K. The apparatus' energy resolution (E/DeltaE) can be as high as 1000 and its angular resolution can be adjusted between 0.3 degrees and 3 degrees . PMID- 30278703 TI - Automated reactive accelerated aging for rapid in vitro evaluation of neural implant performance. AB - Novel therapeutic applications for neural implants require miniaturized devices. Miniaturization imposes stricter requirements for reliability of materials. Pilot clinical studies suggest that rapid failure of the miniaturized neural implants in the body presents a major challenge for this type of technology. Traditional evaluations of neural implant performance over clinically relevant durations present time- and resource-intensive experiments in animals. Reactive accelerated aging (RAA) is an in vitro test platform that was developed to expedite durability testing of neural implants, as a screening technique designed to simulate the aggressive physiological environment experienced by the implants. This approach employs hydrogen peroxide, which mimics reactive oxygen species, and a high temperature to accelerate chemical reactions that lead to device degradation similar to that found with devices implanted in vivo. The original RAA system required daily manual maintenance and was prone to variability in performance. To address these limitations, this work introduces automated reactive accelerated aging (aRAA) with closed-loop monitoring components that make the system simple, robust, and scalable. The core novel technology in the aRAA is electrochemical detection for feedback control of hydrogen peroxide concentration, implemented with simple off-the-shelf components. The aRAA can run multiple parallel experiments for high-throughput device testing and optimization. For this reason, the aRAA provides a simple tool for rapid in vitro evaluation of the durability of neural implants, ultimately expediting the development of a new generation of miniaturized devices with a long functional lifespan. PMID- 30278704 TI - A color x-ray camera for 2-6 keV using a mass produced back illuminated complementary metal oxide semiconductor sensor. AB - There are several reports in the scientific literature of the use of mass produced charge coupled device or complementary metal oxide semiconductor (CMOS) sensors as x-ray detectors that combine high spatial resolution with significant energy resolution. Exploiting a relatively new especially favorable ambient temperature back-illuminated CMOS sensor, we report the development of a spectroscopic x-ray camera having particularly impressive performance for 2-6 keV photons. This instrument has several beneficial characteristics for advanced x ray spectroscopy studies in the laboratory, at synchrotron light sources, at x ray free electron lasers, or when using pulsed x-ray sources such as for laser plasma physics research. These characteristics include fine position and energy resolution for individual photon events, high saturation rates, frame rates above 100 Hz, easy user maintenance for damaged sensors, and software for real-time processing. We evaluate this camera as an alternative to traditional energy dispersive solid-state detectors, such as silicon drift detectors, and also illustrate its use in a very high resolution wavelength-dispersive x-ray fluorescence spectrometer (i.e., x-ray emission spectrometer) that has recently been reported elsewhere [W. M. Holden et al., Rev. Sci. Instrum. 88(7), 073904 (2017)]. PMID- 30278705 TI - A novel, tunable, multimodal microwave system for microwave reflectometry system. AB - Based on a new technique, a tunable, multi-channel system that covers the Q-band (33-55 GHz) is presented in this article. It has a potential use of the Doppler backscattering system diagnostic that can measure the turbulence radial correlation and the perpendicular velocity of turbulence by changing the incident angle. The system consists primarily of a double-sideband (DSB) modulation and a multiplier, which creates four probing frequencies. The probing frequency enables the simultaneous analysis of the density fluctuations and flows at four distinct radial regions in tokamak plasma. The amplitude of the probing frequency can be adjusted by the initial phase of the intermediate frequency (IF) input from the double-sideband, and the typical flatness is less than 10 dB. The system was tested in the lab with a rotating grating, and the results show that the system can operate in the frequency range of 33-55 GHz with a Q-band multitude and that the power of each channel can be adjusted by the phase of the IF input of DSB. PMID- 30278706 TI - Chemical-vapor deposited ultra-fast diamond detectors for temporal measurements of ion bunches. AB - This article reports on the development of thin diamond detectors and their characterization for their application in temporal profile measurements of subnanosecond ion bunches. Two types of diamonds were used: a 20 MUm thin polycrystalline chemical vapor deposited (CVD) diamond and a membrane with a thickness of (5 +/- 1) MUm etched out of a single crystal (sc) CVD diamond. The combination of a small detector electrode and an impedance matched signal outlet leads to excellent time response properties with a signal pulse resolution (FWHM) of tau = (113 +/- 11) ps. Such a fast diamond detector is a perfect device for the time of flight measurements of MeV ions with bunch durations in the subnanosecond regime. The scCVD diamond membrane detector was successfully implemented within the framework of the laser ion generation handling and transport project, in which ion beams are accelerated via a laser-driven source and shaped with conventional accelerator technology. The detector was used to measure subnanosecond proton bunches with an intensity of 108 protons per bunch. PMID- 30278707 TI - Note: Knife edge skimming for improved separation of molecular species by the deflector. AB - A knife edge for shaping a molecular beam is described to improve the spatial separation of the species in a molecular beam by the electrostatic deflector. The spatial separation of different molecular species from each other as well as from atomic seed gas is improved. The column density of the selected molecular-beam part in the interaction zone, which corresponds to higher signal rates, was enhanced by a factor of 1.5, limited by the virtual source size of the molecular beam. PMID- 30278708 TI - Multimode optical fiber photonic doppler velocimetery. AB - A new optical fiber head for Photonic Doppler Velocimetry (PDV) made from a combination of fiber types [multimode (MM) and single-mode (SM)] and lenses is described. The input laser beam is delivered by a SM fiber and imaged onto the target by simple optics, including an imaging lens centered inside a larger lens, whose role is to collect and image the back reflected light into the MM collection fiber. The large core of the MM fiber enhances the collection efficiency and also reduces its dependence on the target angle. Transmission through the MM fiber reduces the heterodyne fringe visibility considerably, but the Fourier analysis still enables very accurate resolution of the fringe frequency (and hence the velocity). The new PDV head with 20 GHz bandwidth was tested in a dynamical shock wave experiment to measure velocities of ~3 km/s (~3.9 GHz), and the results agreed very well with measurements by a standard SM PDV. PMID- 30278709 TI - Note: Optical filter method for high-resolution magnetostriction measurement using fiber Bragg grating under millisecond-pulsed high magnetic fields at cryogenic temperatures. AB - High-resolution magnetostriction measurement of DeltaL/L ~ 10-6 at a speed of 5 MHz is performed using the optical filter method as the detection scheme for the fiber Bragg grating (FBG) based strain monitor under 35-ms pulsed high magnetic fields up to 45 T at 2.2 K. The resolution of magnetostriction is about the same order as the conventionally reported value from FBG based magnetostriction measurement systems for millisecond pulsed magnetic fields. The measurement speed is ~100 times the conventional ones. The present system can be a faster alternative for the conventional FBG based magnetostriction measurement system for millisecond pulsed high magnetic fields. PMID- 30278710 TI - A quasi-coaxial HV rolled pulse forming line. AB - A quasi-coaxial high-voltage (HV) rolled pulse forming line (rolled PFL) is researched in this paper. The PFL is rolled n circles on a support cylinder simultaneously by two layers of copper foil electrodes and two layers of insulation dielectrics. The first circle of the two electrodes are elicited in opposite directions along the axis, acting as the quasi-coaxial output structure of the PFL, and the left n - 1 circles of the PFL form a complete rolled strip line of n - 1 circles. The rolled PFL is convenient to realize HV insulation and is able to output a pulse with good quality. Characteristic parameters of the PFL are designed theoretically. Besides, the pulse discharge process of the PFL is simulated by computer simulation technology (CST) modeling, and the simulation result verifies the correctness of theory design. Furthermore, a rolled PFL with a characteristic impedance of 4.4 Omega is developed. The test characteristic impedance of the developed PFL by the incident pulse method confirms to the theory design. The discharge voltage waveform with a full width at half maximum of 57 ns of the PFL is acquired, which has a rise time of 6.8 ns. The HV test of the rolled PFL is carried out, and a discharge current pulse with an amplitude of 7 kA is acquired when the PFL is charged to 70 kV. It is calculated that the developed PFL has an energy storage density of 2.5 J/l. A Tesla generator based on 13 stages of rolled PFLs is designed, which is expected to output a 450 kV pulse with a duration of 100 ns on a 40-Omega match load. The discharge waveform of the generator is simulated by the CST software. The simulative output pulse has a rise time of 5 ns, with a flattop jitter less than 5%. PMID- 30278711 TI - Suppression of higher diffraction orders in the extreme ultraviolet range by a reflective quasi-random square nano-pillar array. AB - Higher diffraction orders of a grating introduce so-called harmonics contamination that leads to ambiguity in the spectral data. They are also present in "monochromatic" output beams processed by grating monochromators at synchrotron radiation facilities, making calibration results of optical elements and detectors imprecise. The paper describes a new design of a reflective quasi random square nano-pillar array grating to reduce the amount of data of the grating relief pattern that is 10 cm in size and suppresses higher diffraction orders in the extreme ultraviolet range. In addition, a laboratory-scale grating monochromator equipped with the grating has been developed to test its spectroscopy characteristics at grazing incidence. The results illustrate that it can suppress higher diffraction orders and maintain the spectral resolving power as an ordinary grating at grazing incidence. The grating has great potential in harmonics suppression in the field of synchrotron radiation, spectral diagnostics of plasma, and astrophysics. PMID- 30278712 TI - An angular-resolved multi-channel Thomson parabola spectrometer for laser-driven ion measurement. AB - A multi-channel Thomson parabola spectrometer was designed and employed to diagnose ion beams driven by intense laser pulses. Angular-resolved energy spectra for different ion species can be measured in a single shot. It contains parallel dipole magnets and wedged electrodes to fit ion dispersion of different charge-to-mass ratios. The diameter and separation of the entrance pinhole channels were designed properly to provide sufficient resolution and avoid overlapping of dispersed ion beams. To obtain a precise energy spectral resolving, three-dimensional distributions of the electric and magnetic fields were simulated. Experimental measurement of energy-dependent angular distributions of target normal sheath accelerated protons and deuterons was demonstrated. This novel compact design provides a comprehensive characterization for ion beams. PMID- 30278713 TI - Non-perturbing THz generation at the Tsinghua University Accelerator Laboratory 31 MeV electron beamline. AB - In recent experiments at Tsinghua University Accelerator Laboratory, the 31 MeV electron beam, which has been compressed to subpicosecond pulse durations, has been used to generate high peak power, narrow band Terahertz (THz) radiation by transit through different slow wave structures, specifically quartz capillaries metallized on the outside. Despite the high peak powers that have been produced, the THz pulse energy is negligible compared to the energy of the electron beam. Therefore, the THz generation process can be complementary to other beamline applications like plasma wakefield acceleration studies and Compton x-ray free electron lasers. This approach can be used at x-ray free electron laser beamlines, where THz radiation can be generated without disturbing the x-ray generation process. In the experiment reported here, a high peak current electron beam generated strong narrow band (~1% bandwidth) THz signals in the form of a mixture of TM01 and TM02 modes. Each slow wave structure is completed with a mode converter at the end of the structure that allows for efficient (>90%) power extraction into free space. In the experiment, both modes in these two dielectric loaded waveguides TM01 (0.3 THz/0.5 THz) and TM02 (0.9 THz/1.3 THz) were explicitly measured with an interferometer. The THz pulse energy was measured with a calibrated Golay cell at a few MUJ. PMID- 30278714 TI - Note: Controlling the length of plasmonic tips obtained by pulsed electrochemical etching. AB - We present a method to control the length of plasmonic gold tips through pulsed electrochemical etching. This method uses a cut-off circuit to interrupt the etching when the desired length is achieved, paving the way to tune the plasmonic properties of these tips through their shape. The control of the tip length by monitoring the cell voltage is the result of a study of the etching dynamics. The resulting tips possess a low apex radius and a small opening angle, allowing for high spatial resolution both in topography and in near-field imaging. The plasmonic behavior was confirmed in tip-enhanced Raman spectroscopy. PMID- 30278715 TI - A pressure-tuned Fabry Perot interferometer for laser frequency stabilization and tuning. AB - We present a simple, inexpensive pressure-tuned Fabry Perot interferometer which can be used to frequency stabilize and tune a laser when no suitable atomic reference is available. Our design, made largely from off-the-shelf parts, yields a tuning range of about 4 GHz and offers an absolute tuning accuracy of better than 1 MHz. The interferometer, which uses air as its working medium, is characterized by a low thermal drift rate of order 1 MHz per hour. PMID- 30278716 TI - Note: Development of a triple resonance pulse transformer based on magnetic core transformer. AB - In this paper, a triple resonance pulse transformer based on a magnetic core transformer is developed, which uses the first peak of the output voltage to charge the load capacitor. A compact magnetic core pulse transformer is developed, which uses an innovative bi-conical specific geometry. Based on this magnetic core pulse transformer, the triple resonance circuit is built by adding a tuning capacitor and a tuning inductor between this transformer and a pulse forming line (PFL). The tuning capacitor is designed to be an irregular coaxial capacitor with a capacitance of 70 pF and the tuning inductor is made as a single layer air core cylindrical inductor. The experimental results indicate that the peak output voltage of the triple resonance pulse transformer is about 530 kV and the rise time is about 790 ns. The peak voltage across PFL is 1.6 times the peak voltage across the magnetic core transformer. It is feasible to develop a magnetic core pulse transformer into a triple resonance pulse transformer. PMID- 30278717 TI - Note: Observation of the angular distribution of an x-ray characteristic emission through a periodic multilayer. AB - We present the observation of the angular distribution of a characteristic x-ray emission through a periodic multilayer. The emission coming from the substrate on which the multilayer is deposited is used for this purpose. It is generated upon proton irradiation through the multilayer and detected with an energy sensitive CCD camera. The observed distribution in the low detection angle range presents a clear dip at a position characteristic of the emitting element. Thus, such a device can be envisaged as a spectrometer without mechanical displacement and using various ionizing sources (electrons, x-rays, and ions), their incident direction being irrelevant. PMID- 30278718 TI - Implementation of ultraviolet Thomson scattering on SG-III laser facility. AB - An ultraviolet Thomson-scattering system has been designed and implemented on the Shenguang-III laser facility, a 48-beam, 3omega (351 nm), 180 kJ-level laser driver for high energy density physics and inertial confinement fusion researches. The 4omega (263.3 nm) probe beam of the Thomson-scattering system is injected from the north pole (top) of the target chamber, with an assistant beam pointing monitor to achieve high pointing accuracy. The Thomson-scattered light is collected by a double-Cassegrain optical transmission system, which provides an achromatic image over a wide wavelength range of 200-800 nm. A novel on-line alignment method is developed and applied to the diagnostic system, ensuring a volumetric positioning accuracy of ~30 MUm for the scattering volume. An online calibration is also conducted to provide the wavelength benchmark and the spectral resolution of the system. This Thomson-scattering system has been tested in a complicated experimental environment with gas-filled hohlraums, and a high quality ion feature of the scattered light has been obtained. PMID- 30278719 TI - A 30 GW subnanosecond solid-state pulsed power system based on generator with semiconductor opening switch and gyromagnetic nonlinear transmission lines. AB - This article describes a subnanosecond solid-state pulsed power system in which an input pulse from a generator with a semiconductor opening switch (generator) is amplified in power and is shortened in time by a two-stage magnetic compressor based on gyromagnetic nonlinear transmission lines. In this approach, the line of each stage operates as a magnetic compression line (MCL) which is realized when the duration of the input pulse is close to the period of oscillations generated by the line. The compression system contains two series connected lines MCL1 and MCL2 with a wave impedance of 40 Omega. The input pulse has a duration of 7 ns and an amplitude of 500 kV. After two compression stages, the pulse amplitude increases to 1.1 MV and the peak power increases from 6 to 30 GW, while the pulse duration transits into subnanosecond range (0.65 ns). In the burst mode, the system operates at a pulse repetition frequency up to 1 kHz. PMID- 30278720 TI - An actively shielded gradient coil design for use in planar MRI systems with limited space. AB - In planar magnetic resonance imaging (MRI) systems, gradient coils are usually placed within a very limited space owing to the physical constraints of the small gap size (pole-pole) distance of the permanent magnet. Typically, the unshielded or partially shielded design scheme is adopted to generate required magnetic fields with reduced system costs. However, non-fully shielded coils can induce large eddy currents on the surrounding metal structures, including magnet poles, that significantly impact the imaging performance. This paper elaborates a new design strategy to resolve the limited space problem. Using the peripheral sections of the MRI system, a set of actively shielded gradient coils are purposefully designed. Between the two magnet poles, the actively shielded gradient coils occupy merely four coil layers (six coil layers are usually required), which offers an excellent shielding effect, thus reducing the image distortions. The saved space can be used to integrate a high-efficient cooling system. Moreover, the design scheme does not significantly increase the fabricating complexity. PMID- 30278721 TI - Cylindrical hot refractory anode vacuum arc (CHRAVA). AB - We present a study of a novel vacuum arc deposition system composed of a water cooled aluminum cathode and a hot refractory anode. The plasma of the arc system was diagnosed using a cylindrical electrostatic probe. It was found that the mean electron temperature was ~2 eV, the plasma density could be varied in the range of 0.5-6 * 1016 m-3, and the ion flux was between 0.06 and 0.35 A m-2. Optical emission spectroscopy measurements showed the presence of emission lines corresponding to Al i and Al ii. The characterization of the coatings showed that the deposition rate varied from 0.8 to 4 nm/s and the surface roughness (Ra) of the films was as low as 25 nm. We demonstrated that it was possible to deposit films with low macroparticle densities, overcoming the principal disadvantage of the vacuum arc process. Measurements of the arc voltage and current were performed as a function of time and the applied magnetic field. The anode temperature was measured using a pyrometer through a ZnS window as a function of time and arc current, and the maximum value was 1800 degrees C with heating rates of up to 110 degrees C/s. PMID- 30278722 TI - Elliptically bent crystal x-ray spectrometer for time-resolved laser plasma experiments. AB - Measuring time-resolved spectra is crucial in inertial confinement fusion and radiation source development experiments. An elliptically bent crystal spectrometer is designed to measure X-rays in the range of 2.5-11.0 keV, which was achieved using four different lattice spacings of 0.8512, 0.6687, 0.4246, and 0.2749 nm with spectral resolution E/deltaE of ~500. The X-rays emitted from a source at one focus of the ellipse undergo Bragg reflection off a crystal and pass through the second focus of the ellipse to a streak camera slit with 18-mm length and 80-MUm width to generate a time-resolved spectrum. An alignment method for the time-resolved spectrometer was developed with the straight line connecting the centers of the two small holes on the fabricated substrate being the axis of the ellipse, thus allowing the spacing between the source and the elliptical crystal to be tuned to couple with the streak camera. The time resolved spectrometer's performance was experimentally tested at the Shenguang II laser facility. The results indicate that its performance is close to that predicted theoretically. PMID- 30278723 TI - Measurements of electron density profile by frequency modulated continuous wave reflectometer in the T-10 tokamak using high magnetic field side probing and extraordinary mode lower cutoff. AB - A new, previously unused combination of the high magnetic field side probing and the lower extraordinary mode cutoff was used in the T-10 tokamak for the electron density profile measurements by using a frequency modulation continuous wave reflectometer. This scheme has a significant advantage for large fusion machines where flat electron density profiles and high electron temperatures are expected. The reflectometer design is based on a common scheme with voltage controlled oscillators, active multipliers, and in-phase/quadrature signal detection. Iterative procedures were applied to calibrate a microwave source frequency and compensate the dispersion of probing signals in the conventional rectangular waveguides used as the transmission lines. About 0.2% stability of the beating frequency was reached after the calibration procedure had been finished. An advanced finite-difference scheme was proposed for the reconstruction of the electron density profile to reduce errors and improve the overall performance of the algorithm. Reconstructed electron density profiles demonstrate good agreement with conventional T-10 diagnostic data. Some specific technical and physical aspects of the diagnostic were also discussed on the basis of T-10 operation experience. PMID- 30278724 TI - Broadband loop gap resonator for nitrogen vacancy centers in diamond. AB - We present an S-band tunable loop gap resonator (LGR), which provides strong, homogeneous, and directionally uniform broadband microwave (MW) drive for nitrogen-vacancy (NV) ensembles. With 42 dBm of input power, the composite device provides drive field amplitudes approaching 5 G over a circular area ?50 mm2 or cylindrical volume ?250 mm3. The wide 80 MHz device bandwidth allows driving all NV Zeeman resonances for bias magnetic fields below 20 G. The device realizes percent-scale MW drive inhomogeneity; we measure a fractional root-mean-square inhomogeneity sigma rms = 1.6% and a peak-to-peak variation sigma pp = 3% over a circular area of 11 mm2 and sigma rms = 3.2% and sigma pp = 10.5% over a larger 32 mm2 circular area. We demonstrate incident MW power coupling to the LGR using two methodologies: a printed circuit board-fabricated exciter antenna for deployed compact bulk sensors and an inductive coupling coil suitable for microscope-style imaging. The inductive coupling coil allows for approximately 2pi steradian combined optical access above and below the device, ideal for envisioned and existing NV imaging and bulk sensing applications. PMID- 30278725 TI - Static and dynamic calibration of torsional spring constants of cantilevers. AB - A method for calibrating the dynamic torsional spring constant of cantilevers by directly measuring the thermally driven motion of the cantilever with an interferometer is presented. Random errors in calibration were made negligible (<1%) by averaging over multiple measurements. The errors in accuracy of +/-5% or +/-10% for both of the cantilevers calibrated in this study were limited only by the accuracy of the laser Doppler vibrometer (LDV) used to measure thermal fluctuations. This is a significant improvement over commonly used methods that result in large and untraceable errors resulting from assumptions made about the cantilever geometry, material properties, and/or hydrodynamic physics of the surroundings. Subsequently, the static torsional spring constant is determined from its dynamic counterpart after careful LDV measurements of the torsional mode shape, backed by finite element analysis simulations. A meticulously calibrated cantilever is used in a friction force microscopy experiment that measures the friction difference and interfacial shear strength (ISS) between graphene and a silicon dioxide AFM probe. Accurate calibration can resolve discrepancies between different experimental methods, which have contributed to a large scatter in the reported friction and ISS values in the literature to date.

AB - This paper presents an open and flexible digital phase-locked loop optimized for laser stabilization systems. It is implemented on a cheap and easily accessible FPGA-based digital electronics platform (Red Pitaya) running a customizable open source firmware. A PC-based software interface allows controlling the platform and optimizing the loop parameters remotely. Several tools are included to allow measurement of quantities of interest smoothly and rapidly. To demonstrate the platform's capabilities, we built a fiber noise canceller over a 400 m fiber link. Noise cancellation was achieved over a 30 kHz bandwidth, a value limited mainly by the delays introduced by the actuator and by the round-trip propagation over the fiber link. We measured a total latency of 565 ns for the platform itself, limiting the theoretically achievable control bandwidth to approximately 225 kHz. PMID- 30278727 TI - Multiplexed characterization of complex gas-phase mixtures combining chirped pulse Fourier transform microwave spectroscopy and VUV photoionization time-of flight mass spectrometry. AB - We report details of the design and operation of a single apparatus that combines Chirped-Pulse Fourier Transform Microwave (CP-FTMW) spectroscopy with vacuum ultraviolet (VUV) photoionization Time-of-Flight Mass Spectrometry (TOFMS). The supersonic expansion used for cooling samples is interrogated first by passing through the region between two microwave horns capable of broadband excitation and detection in the 2-18 GHz frequency region of the microwave. After passing through this region, the expansion is skimmed to form a molecular beam, before being probed with 118 nm (10.5 eV) single-photon VUV photoionization in a linear time-of-flight mass spectrometer. The two detection schemes are powerfully complementary to one another. CP-FTMW detects all components with significant permanent dipole moments. Rotational transitions provide high-resolution structural data. VUV TOFMS provides a gentle and general method for ionizing all components of a gas phase mixture with ionization thresholds below 10.5 eV, providing their molecular formulae. The advantages, complementarity, and limitations of the combined methods are illustrated through results on two gas phase mixtures made up of (i) three furanic compounds, two of which are structural isomers of one another, and (ii) the effluent from a flash pyrolysis source with o-guaiacol as the precursor. PMID- 30278728 TI - Next-generation diamond cell and applications to single-crystal neutron diffraction. AB - A diamond cell optimized for single-crystal neutron diffraction is described. It is adapted for work at several of the single-crystal diffractometers of the Spallation Neutron Source and the High Flux Isotope Reactor at the Oak Ridge National Laboratory (ORNL). A simple spring design improves portability across the facilities and affords load maintenance from offline pressurization and during temperature cycling. Compared to earlier prototypes, pressure stability of polycrystalline diamond (Versimax(r)) has been increased through double-conical designs and ease of use has been improved through changes to seat and piston setups. These anvils allow ~30%-40% taller samples than possible with comparable single-crystal anvils. Hydrostaticity and the important absence of shear pressure gradients have been established with the use of glycerin as a pressure medium. Large single-crystal synthetic diamonds have also been used for the first time with such a clamp-diamond anvil cell for pressures close to 20 GPa. The cell is made from a copper beryllium alloy and sized to fit into ORNL's magnets for future ultra-low temperature and high-field studies. We show examples from the Spallation Neutron Source's SNAP and CORELLI beamlines and the High Flux Isotope Reactor's HB-3A and IMAGINE beamlines. PMID- 30278729 TI - The phosphor temperature measurement of white light-emitting diodes based on magnetic nanoparticle thermometer. AB - There is much debate about whether the junction temperature or phosphor temperature is higher in white light-emitting diodes (LEDs). The main reason is that the junction and phosphor temperatures cannot be measured directly using traditional temperature measurement tools. In this study, a magnetic nanoparticle thermometer, a nondestructive and precise temperature measurement tool, is introduced and described in detail. The model, measurement principle, and experimental setup are described. The temperature of the phosphor layer and the top surface of the P-N junction in white LEDs was measured directly using the magnetic nanoparticle thermometer, and the results show that the phosphor layer temperature was higher than the chip top surface temperature at different input voltages, providing a reference for relative researchers. PMID- 30278730 TI - Signal-to-noise ratio analysis and improvement for fluorescence tomography imaging. AB - CCD-based fluorescence tomography is widely used for small animal whole-body imaging. In this report, systematic signal-to-noise ratio (SNR) analyses of a fluorescence tomography imaging (FTI) system were performed, resulting in an easy to-follow strategy to optimize hardware configurations and operational conditions for acquiring high-quality imaging data and for improving the overall system performance. Phantom experiments were conducted to demonstrate the performance improvement by these optimizations. The improved performance was further verified by imaging a tumor-bearing mouse in vivo. This report provides general and practical guidelines for setting up a high-performance electron multiplying charge coupled device based FTI system to achieve an optimized SNR, which can be useful for future FTI technology development. PMID- 30278731 TI - Metrological large range magnetic force microscopy. AB - A new metrological large range magnetic force microscope (Met. LR-MFM) has been developed. In its design, the scanner motion is measured by using three laser interferometers along the x, y, and z axes. Thus, the scanner position and the lift height of the MFM can be accurately and traceably determined with subnanometer accuracy, allowing accurate and traceable MFM measurements. The Met. LR-MFM has a measurement range of 25 mm * 25 mm * 5 mm, larger than conventional MFMs by almost three orders of magnitude. It is capable of measuring samples from the nanoscale to the macroscale, and thus, it has the potential to bridge different magnetic field measurement tools having different spatially resolved scales. Three different measurement strategies referred to as Topo&MFM, MFMXY, and MFMZ have been developed. The Topo&MFM is designed for measuring topography and MFM phase images, similar to conventional MFMs. The MFMXY differs from the Topo&MFM as it does not measure the topography profile of surfaces at the second and successive lines, thus reducing tip wear and saving measurement time. The MFMZ allows the imaging of the stray field in the xz- or yz-planes. A number of measurement examples on a multilayered thin film reference sample made of [Co(0.4 nm)/Pt(0.9 nm)]100 and on a patterned magnetic multilayer [Co(0.4 nm)/Pt(0.9 nm)]10 with stripes with a 9.9 MUm line width and 20 MUm periodicity are demonstrated, indicating excellent measurement performance.

AB - The engineering diffractometer 2nd Generation Neutron Residual Stress Facility (NRSF2) at the Oak Ridge National Laboratory's High Flux Isotope Reactor was built specifically for the mapping of residual strains. NRSF2 is optimized to investigate a wide range of engineering materials by providing the user a selection of monochromatic neutron wavelengths to maintain the selected Bragg reflection near 2theta = 90 degrees , which is the optimal scattering geometry for strain mapping. Details of the instrument configuration and operation are presented, and considerations for experimental planning are also discussed. Selected examples of recent residual stress work completed with NRSF2 are presented to highlight capabilities. PMID- 30278733 TI - Verification of Doppler coherence imaging for 2D ion velocity measurements on DIII-D. AB - Coherence Imaging Spectroscopy (CIS) has emerged as a powerful tool for investigating complex ion phenomena in the boundary of magnetically confined plasma devices. The combination of Fourier-transform interferometry and high resolution fast-framing cameras has made it possible to make sensitive velocity measurements that are also spatially resolved. However, this sensitivity makes the diagnostic vulnerable to environmental effects including thermal drifts, vibration, and magnetic fields that can influence the velocity measurement. Additionally, the ability to provide an absolute calibration for these geometries can be impacted by differences in the light-collection geometry between the plasma and reference light source, spectral impurities, and the presence of thin films on in-vessel optics. This paper discusses the mitigation of these effects and demonstration that environmental effects result in less than 0.5 km/s error on the DIII-D CIS systems. A diagnostic comparison is used to demonstrate agreement between CIS and traditional spectroscopy once tomographic artifacts are accounted for. PMID- 30278734 TI - Atomic scale shot-noise using cryogenic MHz circuitry. AB - By implementing dedicated cryogenic circuitry operating in the MHz regime, we have developed a scanning tunneling microscope (STM) capable of conventional, low frequency (<10 kHz), microscopy as well spectroscopy and shot-noise detection at 1 MHz. After calibrating our AC circuit on a gold surface, we illustrate our capability to detect shot-noise at the atomic scale and at low currents (<1 nA) by simultaneously measuring the atomically resolved differential conductance and shot-noise on the high temperature superconductor Bi2Sr2CaCu2O8+x . We further show our direct sensitivity to the temperature of the tunneling electrons at low voltages. Our MHz circuitry opens up the possibility to study charge and correlation effects at the atomic scale in all materials accessible to STM. PMID- 30278735 TI - A laser scanning microscope executing intraframe polarization switching of the illumination beam. AB - The polarization of the illumination beam in a beam scanning microscope such as the confocal microscope plays an important role in extracting the orientational information of the molecules in the specimen. In this paper, we present the development of a beam scanning microscope comprising a custom designed optical arrangement to obtain images of the same target with different polarizations of the illumination beam. The optical arrangement, based on a ferroelectric liquid crystal spatial light modulator (FELCSLM), can generate homogeneous as well as non-homogeneous user defined polarization profiles over the cross-sectional area of the illumination beam. Here, we employ a computer generated holography technique and exploit the programmability of the FELCSLM display to considerably reduce the time gap between two successive illuminations of each location of the specimen with two different polarizations. We demonstrate the working of the beam scanning microscope where the polarization profile of the illumination beam is switched at the end of every line scanned, in contrast to a conventional beam scanning microscope where the polarization can be switched at the end of every frame scanned. Preliminary experimental results obtained using a polarization sensitive target confirm the feasibility of the proposed scheme. PMID- 30278736 TI - Note: Simultaneous modulation transfer spectroscopy on transitions of multiple atomic species for compact laser frequency reference modules. AB - We present a technique for simultaneous laser frequency stabilization on transitions of multiple atomic species with a single optical setup. The method is based on modulation transfer spectroscopy, and the signals are separated by modulating at different frequencies and electronically filtered. As a proof of concept, we demonstrate simultaneous spectroscopy of the potassium D1, D2 and rubidium D2 transitions. The technique can be extended in principle to other atomic species given the availability of optics and cells and allows the development of versatile and compact frequency reference modules. PMID- 30278737 TI - A neutral wind instrument for nano-satellite platforms. AB - Here we describe the first neutral wind sensor developed specifically for use on resource limited nano-satellite platforms. The instrument is a next generation redesign of the ram wind sensor flown on the Communications/Navigation Outage Forecasting System satellite for measurements of neutral velocity, temperature, and composition. Results of subsystem tests in vacuum conditions show low-power operation, promising design, and good resolution of measured parameters over the operational pressure and energy ranges expected in the low Earth orbit environment. PMID- 30278738 TI - A plasma-triggered gas switch. AB - This paper presents a low-jitter, low-trigger-threshold, high-dielectric-constant ceramic, plasma-triggered gas switch developed for pulsed power generators. We also discuss the principles behind the switch and the experiments and numerical calculations used. The electron emission and surface flashover in the trigger structure are used to create the initial plasma for switch breakdown. The experimental results show that the switch is triggered stably with a negative pulse of -50 kV peak and has a breakdown delay time jitter of 2-3 ns. In this jitter performance, the switch has a switch coefficient below 20%, and a peak current-carrying ability of at least +/-5 kA in dry air at atmospheric pressure. The switch can also be reliably triggered with a switch coefficient of 49.7% and an over-voltage ratio of only 0.16 in dry air. PMID- 30278739 TI - Investigation of multifilament MgB2 superconducting joint technique for development of MRI magnets. AB - This study presents the investigation of superconducting joints fabricated using multifilament magnesium diboride (MgB2) wires for the development of persistent current mode magnetic resonance imaging (MRI) magnets. The critical current of the jointed samples decreased with increasing cutting angle because the smaller cutting angle allowed greater exposure of the MgB2 filament, thereby increasing the contact area for the wire-bulk-wire connection. In addition, an appropriate pressing pressure (300 MPa) was necessary to establish the multifilament MgB2 joint without significant degradation of superconducting properties. The resistance of the optimal MgB2 joint, measured using the field-decay technique, was <1.5 * 10-14 Omega. Therefore, the proposed joint technique can be employed for developing multifilament MgB2 MRI magnets operating in the persistent-current mode. PMID- 30278740 TI - Investigation of comb-type pulse forming line with low impedance. AB - Development of pulsed power technology is toward higher power, longer duration, and more compact structures. Compact coaxial propylene carbonate pulse forming lines are widely used in the application of pulsed power systems. In order to further lengthen the duration and decrease the geometrical sizes of pulsed power systems, a comb-type pulse forming line is adopted. It is a slow-wave structure with a comb-type inner electrode. In this paper, the operation principle, theoretical analysis, numerical simulation, and experimental investigation of the comb-type forming line are carried out, respectively. First, the operation principle is briefly introduced. The principle to increase the duration is explained. Second, the theoretical analyses about the dispersion relation are proposed. Third, the PSpice model is built by the L-C network. Based on the calculated parameters, the electrical circuit is simulated. A Computer Simulation Technology (CST) model is also built, which allows for a straightforward coupling of electric and magnetic (EM) simulation and circuit simulation. Finally, the comb-type pulse forming line is experimentally tested and verified. For the comb type propylene carbonate forming line with a 67 cm length to replace the traditional coaxial one, it has an impedance of 8 Omega and a duration of 64 ns. Experimental data on its test results are given. The experimental results are in accordance with the numerical simulations. The investigation approved the comb type pulse forming line feasible and set a solid foundation for its application in the pulsed power system. PMID- 30278741 TI - Cryo scanning transmission x-ray microscope optimized for spectrotomography. AB - A cryo scanning transmission X-ray microscope, the cryo-STXM, has been designed and commissioned at the Canadian Light Source synchrotron. The instrument is designed to operate from 100 to 4000 eV (lambda = 12.4 - 0.31 nm). Users can insert a previously frozen sample, through a load lock, and rotate it +/-70 degrees in the beam to collect tomographic data sets. The sample can be maintained for extended periods at 92 K primarily to suppress radiation damage and a pressure on the order of 10-9 Torr to suppress sample contamination. The achieved spatial resolution (30 nm) and spectral resolution (0.1 eV) are similar to other current soft X-ray STXMs, as demonstrated by measurements on known samples and test patterns. The data acquisition efficiency is significantly more favorable for both imaging and tomography. 2D images, 3D tomograms, and 4D chemical maps of automotive hydrogen fuel cell thin sections are presented to demonstrate current performance and new capabilities, namely, cryo spectrotomography in the soft X-ray region. PMID- 30278742 TI - Record indoor magnetic field of 1200 T generated by electromagnetic flux compression. AB - A peak field of 1200 T was generated by the electromagnetic flux-compression (EMFC) technique with a newly developed megagauss generator system. Magnetic fields closely up to the turn-around peak were recorded by a reflection-type Faraday rotation magnetic-field optical-fiber probe. The performance was analyzed and compared with data obtained by the preceding EMFC experiments to show a significant increase in the liner imploding speed of up to 5 km/s. PMID- 30278743 TI - Extending the limits of powder diffraction analysis: Diffraction parameter space, occupancy defects, and atomic form factors. AB - Although the determination of site occupancies is often a major goal in Rietveld refinement studies, the accurate refinement of site occupancies is exceptionally challenging due to many correlations and systematic errors that have a hidden impact on the final refined occupancy parameters. Through the comparison of results independently obtained from neutron and synchrotron powder diffraction, improved approaches capable of detecting occupancy defects with an exceptional sensitivity of 0.1% (absolute) in the class of layered NMC (Li[NixMnyCoz]O2) Li ion battery cathode materials have been developed. A new method of visualizing the diffraction parameter space associated with crystallographic site scattering power through the use of f* diagrams is described, and this method is broadly applicable to ternary compounds. The f* diagrams allow the global minimum fit to be easily identified and also permit a robust determination of the number and types of occupancy defects within a structure. Through a comparison of neutron and X-ray diffraction results, a systematic error in the synchrotron results was identified using f* diagrams for a series of NMC compounds. Using neutron diffraction data as a reference, this error was shown to specifically result from problems associated with the neutral oxygen X-ray atomic form factor and could be eliminated by using the ionic O2- form factor for this anion while retaining the neutral form factors for cationic species. The f* diagram method offers a new opportunity to experimentally assess the quality of atomic form factors through powder diffraction studies on chemically related multi-component compounds. PMID- 30278744 TI - Advances in utilizing event based data structures for neutron scattering experiments. AB - This article strives to expand on existing work to demonstrate advancements in data processing made available using event mode measurements. Most spallation neutron sources in the world have data acquisition systems that provide event recording. The new science that is enabled by utilizing event mode has only begun to be explored. In the past, these studies were difficult to perform because histograms forced dealing with either large chunks of time or a large number of files. With event based data collection, data can be explored and rebinned long after the measurement has completed. This article will review some of the principles of event data and how the method opens up new possibilities for in situ measurements, highlighting techniques that can be used to explore changes in the data. We also demonstrate the statistical basis for determining data quality and address the challenge of determining how long to measure mid-measurement. Finally, we demonstrate a model independent method of grouping data via hierarchical clustering methods that can be used to improve calibration, reduction, and data exploration. PMID- 30278745 TI - Note: A Laue crystal imager for high energy quasi-monochromatic x-ray. AB - A newly designed transmission type x-ray Laue imager for tens of keV hard x-rays is reported. Compared with the traditional reflection type x-ray crystal imager, the transmission geometry produces a much better image quality for high energy hard x-rays. This system was assessed via a calibration experiment performed at the SPring8 synchrotron radiation facility. With a Ta x-ray fluorescer, the mono energetic x-ray at 70 keV from the synchrotron radiation was converted to an isotropically emitted Ta K-shell source at 57.5 keV and 65 keV. A tungsten pinhole array was employed as the test object, and clear images of the pinholes with a magnification of ~5 were acquired. These images exhibited superior quality in the dispersion plane. As an extension of this work, a slit-free full-spectral Laue imager is proposed for high resolution hard x-ray imaging. PMID- 30278746 TI - The high pressure gas capabilities at Oak Ridge National Laboratory's neutron facilities. AB - The study of samples subjected to high pressure gas is an important asset in materials research and has consequently been a priority of the sample environment development at the Oak Ridge National Laboratory's (ORNL) neutron program. Such effort has resulted in the availability of an extensive combination of pressure cells and gas intensifiers (both commercially available and custom made). These resources are available across both neutron facilities at ORNL: the Spallation Neutron Source and the High Flux Isotope Reactor. Current capabilities include, for example, in situ measurements up to 6 kbar and a 3 kbar hydrogen-capable intensifier with a gas recovery feature. In this communication, we will review the existing suite of high pressure gas capabilities, with special emphasis on recent in-house developments. A number of examples will be presented to illustrate how such capabilities are being deployed on neutron beamlines to enable frontier science.

PMID- 30278748 TI - Transient process based electromagnetic flow measurement methods and implementation. AB - The ordinary electromagnetic flowmeter (EMF) utilizes the steady-state period of the excitation current for measuring the flow rate in order to ensure zero stability and measurement accuracy. In this paper, the transient process of EMF is studied to measure the flow rate so as to realize applications requiring ultra low power consumption, for example, water meters. For this reason, the dynamic excitation current and signal voltage of the transient process are analyzed, and three kinds of transient measurement methods are proposed to determine the relationship between the processing results of the signal voltage and flow rates. They are the voltage-current ratio method, voltage-current differential method, and differential interference compensation method. In order to verify these measurement methods, a DSP (Digital Signal Processor) that is the same processing chip as the current ordinary electromagnetic flow transmitter is selected to design a hardware system of the transmitter, and the excitation current and signal voltage of the transient process are acquired. Analysis of experimental data shows that there is a good linear relationship between the processing results of the signal voltage and flow rates. The software of the electromagnetic flow transmitter based on DSP is developed, and the transient measurement methods are realized in real time so as to perform the water flow calibration experiments and power consumption tests. The experimental results show that the measurement accuracy is 0.5% which is the same as the ordinary EMF. Comparisons of power consumption show that the excitation power consumption of EMF based on the transient measurement principle is 1/1200 of that of the ordinary EMF. PMID- 30278750 TI - Adaptation of a visible wavelength fluorescence microplate reader for discovery of near-infrared fluorescent probes. AB - We present an inexpensive, generalizable approach for modifying visible wavelength fluorescence microplate readers to detect emission in the near infrared (NIR) I (650-950 nm) and NIR II (1000-1350 nm) tissue imaging windows. These wavelength ranges are promising for high sensitivity fluorescence-based cell assays and biological imaging, but the inaccessibility of NIR microplate readers is limiting development of the requisite, biocompatible fluorescent probes. Our modifications enable rapid screening of NIR candidate probes, using short pulses of UV light to provide excitation of diverse systems including dye molecules, semiconductor quantum dots, and metal clusters. To confirm the utility of our approach for rapid discovery of new NIR probes, we examine the silver cluster synthesis products formed on 375 candidate DNA strands that were originally designed to produce green-emitting, DNA-stabilized silver clusters. The fast, sensitive system developed here discovered DNA strands that unexpectedly stabilize NIR-emitting silver clusters.

AB - A novel TE01-TE20 mode converter is designed and fabricated by 3-D printing in this paper. It can realize high-efficiency (>97.5%) mode conversion in broadband from 27 to 40 GHz. Its weight is 0.011 kg only, and its coupling cavity normalized length is 0.39lambda. An out-of-phase power divider is designed to verify the mode converter by observing the difference of output phase and flat frequency characteristics when connected to the mode converter. A sample converter with a power divider was then tested. Flat frequency characteristics for power dividing and anti-phase outputs are obtained in the working bandwidth to verify the mode converter with a good performance of mode conversion. PMID- 30278752 TI - New software protocols for enabling laboratory based temporal CT. AB - Temporal micro-computed tomography (CT) allows the non-destructive quantification of processes that are evolving over time in 3D. Despite the increasing popularity of temporal CT, the practical implementation and optimisation can be difficult. Here, we present new software protocols that enable temporal CT using commercial laboratory CT systems. The first protocol drastically reduces the need for periodic intervention when making time-lapse experiments, allowing a large number of tomograms to be collected automatically. The automated scanning at regular intervals needed for uninterrupted time-lapse CT is demonstrated by analysing the germination of a mung bean (vigna radiata), whilst the synchronisation with an in situ rig required for interrupted time-lapse CT is highlighted using a shear cell to observe granular segregation. The second protocol uses golden-ratio angular sampling with an iterative reconstruction scheme and allows the number of projections in a reconstruction to be changed as sample evolution occurs. This overcomes the limitation of the need to know a priori what the best time window for each scan is. The protocol is evaluated by studying barite precipitation within a porous column, allowing a comparison of spatial and temporal resolution of reconstructions with different numbers of projections. Both of the protocols presented here have great potential for wider application, including, but not limited to, in situ mechanical testing, following battery degradation and chemical reactions. PMID- 30278753 TI - Note: Thermal conductivity measurement of individual porous polyimide fibers using a modified wire-shape 3omega method. AB - Porous polyimide fiber enjoys a good reputation as a high temperature resistant thermal insulation material in an aircraft-carrier, a spacecraft, and other military sophisticated products. Understanding its thermal conductivity is especially important for the design optimization and thermal management in these applications. In this study, a modified wire-shape 3omega method is developed to measure the thermal conductivity of individual porous polyimide fibers, utilizing a platinum layer heater/thermometer deposited along the circumferential direction of the fiber. The new method is first validated using a platinum wire with known thermophysical properties such as thermal conductivity at room temperature and then applied to porous polyimide fibers with diverse porosities. The thermal conductivity of porous polyimide fibers at room temperature is 0.06-0.15 W m-1 K 1, which reflects a good thermal insulation performance. PMID- 30278754 TI - Time filtering of event based neutron scattering data: A pathway to study the dynamic structural responses of materials. AB - Time-resolved diffraction has become a vital tool for probing dynamic responses to an applied stimulus. Such experiments traditionally use hardware solutions to histogram measured data into their respective bin. We will show that a major advantage of event-based data acquisition, which time-stamps measured diffraction data with 100 ns accuracy, is much preferred over hardware histogramming of the data by enabling postprocessing for advanced custom binning using a software solution. This approach is made even more powerful by coupling measured diffraction data with metadata about the applied stimuli and material response. In this work, we present a time-filter approach that leverages the power of event based diffraction collection to reduce stroboscopic data measured over many hours into equally weighted segments that represent subsets of the response to a single cycle of the applied stimulus. We demonstrate this approach by observing ferroelectric/ferroelastic domain wall motion during electric field cycling of BaTiO3. The developed approach can readily be expanded to investigate other dynamic phenomena using complex sample environments. PMID- 30278755 TI - A uniaxial load frame for in situ neutron studies of stress-induced changes in cementitious materials and related systems. AB - For in situ neutron scattering experiments on cementitious materials, it is of great interest to have access to a robust device which can induce uniaxial load on a given solid sample. Challenges involve selection of materials making up the apparatus that are both weak neutron scatterers and yet adequately strong to induce loads of up to a few kilonewtons on the sample. Here, the design and experimental commissioning of a novel load frame is provided with the intended use as a neutron scattering sample environment enabling time-dependent stress induced changes to be probed in an engineering material under compression. The frame is a scaled down version of a creep apparatus, which is typically used in the laboratory to measure deformation due to creep in concrete. Components were optimized to enable 22 MPa of compressive stress to be exerted on a 1 cm diameter cement cylinder. To minimize secondary scattering signals from the load frame, careful selection of the metal components was needed. Furthermore, due to the need to maximize the wide angular detector coverage and signal to noise for neutron total scattering measurements, the frame was designed specifically to minimize the size and required number of support posts while matching sample dimensions to the available neutron beam size. PMID- 30278757 TI - Dual energy-band excitation from a low power Rh anode X-ray tube for the simultaneous determination of low Z and high Z elements (Na-U) using total reflection X-ray fluorescence analysis (TXRF). AB - This article presents results from an experimental setup for a dual energy-band vacuum spectrometer for total-reflection X-ray fluorescence analysis allowing simultaneous efficient excitation of low, medium, and high Z elements. The spectrometer is equipped with an air-cooled 35 W low power Rh X-ray tube and a 17 mm2 silicon drift detector with a thin 8 um beryllium window. A Pd/B4C multilayer monochromator is used at the same time as a Bragg reflector for Rh-Kalpha radiation and as a high-energy cut-off reflector above 5 keV, where the characteristic Rh-L radiation is totally reflected and present in the spectrum of the exciting radiation. This leaves one broad low energy band below 5 keV and one high energy band around the energy of Rh-Kalpha. As Rh-L radiation would be absorbed on its path through air, a new beam entrance system was designed in order to guide the Rh-L photons into the vacuum chamber for efficient excitation of low Z elements. With this setup, elements down to sodium (Z = 11, E = 1.04 keV) could be detected. First results are presented, and spectra obtained in air as well as in vacuum are compared and discussed. Detection limits in the range of 1000 ug/kg for Na and around 140 ug/kg for Mg were achieved using the NIST SRM 1640 (trace elements in water). PMID- 30278756 TI - Note: Multi-gap gas switch with low trigger-threshold voltage by mounting resistors and capacitors in parallel with switch gaps. AB - To reduce the trigger threshold voltage of the multi-gap gas switch used for linear transformer drivers, a method is proposed by mounting resistors and capacitors in parallel with the switch gaps. Based on the circuit model of the six-gap gas switch, the gap voltage distribution during the triggering process is analyzed. When the multi-gap gas switch is triggered, the voltage distribution between gaps is mainly determined by the stray capacitance between electrodes. In such condition, the trigger voltage is not fully applied on the trigger gap, and as a consequence, a higher trigger voltage is required for obtaining a low jitter. The effects of capacitor parameters on the triggering characteristics of the switch are experimentally investigated. Compared with the original switch design, the results indicate that at a charging voltage of +/-80 kV and operating at 60% of the self-breakdown voltage, the trigger voltage is reduced from 110 kV to 75 kV while the 3.2 ns jitter of the switch is preserved. PMID- 30278758 TI - Dynamically enhanced low-coherence interferometry. AB - In the investigations of inhomogeneous media, availability of methods to study the interior of the material without affecting it is valuable. Optical coherence tomography provides such a functionality by providing depth resolved images of semi-transparent objects non-invasively. This is especially useful in medicine and is used not only in research but also in clinical practice. Optical coherence tomography characterizes each cross section by its reflectance. The basic physics principle underlying optical coherence tomography is low-coherence interferometry, which is combined with lateral scanning to produce cross sections. It is clearly desirable to obtain more detailed information regarding each cross section, if available. We have developed a system which measures the fluctuation spectra at all depths in low-coherence interferometry. By providing more information for each cross section, this can in principle be effective in tissue characterization and pathological diagnosis. The system uses the time dependence of the low-coherence interferometry data to obtain the fluctuation spectrum at each depth. Additionally, noise reduction is applied to obtain the spectra without unwanted noise, such as shot-noise, which can swamp the signal. The measurement system is applied to samples with no external stimuli, and depth resolved thermal fluctuation spectra of the samples are obtained. These spectra are compared with their corresponding theoretical expectations and are found to agree. The measurement system requires dualizing the detectors in the low coherence interferometer but otherwise requires little additional equipment. The measurements were performed in ten to a hundred seconds. PMID- 30278759 TI - Broadband longwave radio remote sensing instrumentation.

The receiver is an upgraded version of the VLF AWESOME, completed in 2004, which provided high sensitivity broadband radio measurements of natural lightning emissions, transmitting beacons, and radio emissions from the near Earth space environment. It has been deployed at many locations worldwide and used as the basis for dozens of scientific studies. We present here a significant upgrade to the AWESOME, in which the frequency range has been extended to include the LF and part of the medium frequency (MF) bands, the sensitivity improved by 10-25 dB to be as low as 0.03 fT/ Hz , depending on the frequency, and timing error reduced to 15-20 ns range. The expanded capabilities allow detection of radio atmospherics from lightning strokes at global distances and multiple traverses around the world. It also allows monitoring of transmitting beacons in the LF/MF band at thousands of km distance. We detail the specification of the LF AWESOME and demonstrate a number of scientific applications. We also describe and characterize a new algorithm for minimum shift keying demodulation for VLF/LF transmitters for ionospheric remote sensing applications.

AB - We describe the development and performance of an ultra-high vacuum scanning tunneling microscope working under combined extreme conditions of ultra-low temperatures and high magnetic fields. We combined a top-loading dilution refrigerator and a standard bucket dewar with a bottom-loading superconducting magnet to achieve 4.5 days operating time, which is long enough to perform various spectroscopic-imaging measurements. To bring the effective electron temperature closer to the mixing-chamber temperature, we paid particular attention to filtering out radio-frequency noise, as well as enhancing the thermal link between the microscope unit and the mixing chamber. We estimated the lowest effective electron temperature to be below 90 mK by measuring the superconducting-gap spectrum of aluminum. We confirmed the long-term stability of the spectroscopic-imaging measurement by visualizing superconducting vortices in the cuprate superconductor Bi2Sr2CaCu2O8+delta . PMID- 30278761 TI - FRAC: Fringing-RF-field-activated dc-to-pulse converter for low-energy ion beams. AB - We developed a new type of dc-to-pulse converter, called FRAC (Fringing-RF-field Activated dc-to-pulse Converter) for low-energy ion beams electrostatically accelerated from an ion source. FRAC is based on a radio-frequency quadrupole (RFQ) linear trap technique and works in principle under ultrahigh vacuum conditions. Ions continuously injected into FRAC are decelerated by an alternating longitudinal electric field produced in a distorted radio frequency field around the edge region of RFQ rods. These ions accumulate in FRAC for a significantly long time. This edge effect appears most notably when the energy of incoming ions exceeds the injection barrier potential by less than a few eV and the energy spread is quite small. The ions stacked during the FRAC operation period are ejected as a high intensity pulsed beam. We investigated the performance of FRAC and the capability of some FRAC operation methods developed to enhance the dc-to-pulse conversion efficiency. The maximum conversion efficiencies achieved were 22% and 5.6% at FRAC operation frequencies of 10 and 1 Hz, respectively. The number of ions contained in an output beam pulse with a duration of 500 MUs was in practice 1.6 * 109 ions/pulse at an injected dc beam intensity of 4.6 nA and an operation frequency of 1 Hz.

AB - Electron cyclotron emission imaging on EAST provides direct measurements of the 2 D electron temperature dynamics in a continuous large observation area with high temporal and spatial resolution. Besides the normal MHD investigation, a system with a view field large enough to cover the core plasma region has been applied to extract more plasma information, such as the plasma center location, the deposition location of auxiliary heating, and the core toroidal rotation speed. These results solely based on electron cyclotron emission imaging (ECEI) data are consistent with the results of the equilibrium fitting (EFIT), numerical code, and other diagnostics, which indicate the powerful diagnostic capacity of this ECEI system. PMID- 30278763 TI - Fabrication of a precise ellipsoidal mirror for soft X-ray nanofocusing. AB - In X-ray focusing, grazing incidence mirrors offer advantages of no chromatic aberration and high focusing efficiency. Although nanofocusing mirrors have been developed for the hard X-ray region, there is no mirror with nanofocusing performance in the soft X-ray region. Designing a system with the ability to focus to a beam size smaller than 100 nm at an X-ray energy of less than 1 keV requires a numerical aperture larger than 0.01. This leads to difficulties in the fabrication of a soft X-ray focusing mirror with high accuracy. Ellipsoidal mirrors enable soft X-ray focusing with a high numerical aperture. In this study, we report a production process for ellipsoidal mirrors involving mandrel fabrication and replication processes. The fabricated ellipsoidal mirror was assessed under partial illumination conditions at the soft X-ray beamline (BL25SU) of SPring-8. A focal spot size of less than 250 nm was confirmed at 300 eV. The focusing tests indicated that the proposed fabrication process is promising for X-ray mirrors that have the form of a solid of revolution, including Wolter mirrors. PMID- 30278764 TI - A new elliptical-beam method based on time-domain thermoreflectance (TDTR) to measure the in-plane anisotropic thermal conductivity and its comparison with the beam-offset method. AB - Materials lacking in-plane symmetry are ubiquitous in a wide range of applications such as electronics, thermoelectrics, and high-temperature superconductors, in all of which the thermal properties of the materials play a critical part. However, very few experimental techniques can be used to measure in-plane anisotropic thermal conductivity. A beam-offset method based on time domain thermoreflectance (TDTR) was previously proposed to measure in-plane anisotropic thermal conductivity. However, a detailed analysis of the beam-offset method is still lacking. Our analysis shows that uncertainties can be large if the laser spot size or the modulation frequency is not properly chosen. Here we propose an alternative approach based on TDTR to measure in-plane anisotropic thermal conductivity using a highly elliptical pump (heating) beam. The highly elliptical pump beam induces a quasi-one-dimensional temperature profile on the sample surface that has a fast decay along the short axis of the pump beam. The detected TDTR signal is exclusively sensitive to the in-plane thermal conductivity along the short axis of the elliptical beam. By conducting TDTR measurements as a function of delay time with the rotation of the elliptical pump beam to different orientations, the in-plane thermal conductivity tensor of the sample can be determined. In this work, we first conduct detailed signal sensitivity analyses for both techniques and provide guidelines in determining the optimal experimental conditions. We then compare the two techniques under their optimal experimental conditions by measuring the in-plane thermal conductivity tensor of a ZnO [11-20] sample. The accuracy and limitations of both methods are discussed. PMID- 30278765 TI - X-ray detector based on Mn doped MgAl2O4 and Si photodiode. AB - Luminescence properties of Mn doped MgAl2O4 crystals connected with the Si PIN photodiode (PD) have been evaluated for X-ray detector applications. Mn doped MgAl2O4 crystals emit green colored luminescence peaking at around lambda = 520 nm with CuKalpha irradiation. The intensity of the output signal from Si PD increases linearly with the X-ray intensity of CuKalpha generated with the X-ray tube at a current from 2 mA to 40 mA. The intensity of the X-ray excited luminescence is strongest in the specimen with 3.0 mol. % Mn. Afterglow luminescence is weak in the specimen with 2.0 mol. % Mn. Mn doped MgAl2O4 crystals connected with the Si PD is considered to be a useful X-ray detector. PMID- 30278766 TI - Portable and noise-tolerant magnetic field generation system. AB - We have successfully developed a portable pulsed magnetic field generation system incorporating a number of techniques to avoid the effects of noise, including shielding, a self-power capability, and a high-capability semiconductor switch. The system fits into a cubical box less than 0.5 m in linear dimensions and can easily be installed in experimental facilities, including noisy environments such as high-power laser facilities. The system can generate a magnetic field of several tesla sustainable for several tens of microseconds over a spatial scale of several centimeters. In a high-power laser experiment with Gekko-XII, the system operated stably despite being subjected to a high level of electrical noise from laser shots of 600 J. PMID- 30278767 TI - Tunnel diode resonator for precision magnetic susceptibility measurements in a mK temperature range and large DC magnetic fields. AB - Precision radio-frequency measurements of the magnetic susceptibility using the tunnel diode resonator (TDR) technique are used to study the delicate effects in magnetic and superconducting materials. High resolution (in ppb range) measurements are particularly important for studies of the London and Campbell penetration depths in a superconductor and for the investigation of magnetic transitions in (anti)ferromagnets. Due to the small rf magnetic-excitation in a mOe range, the TDR is especially useful at low-temperatures in a mK range, if Joule heating generated in the TDR circuitry is efficiently removed and the circuit is stabilized with sub-mK precision. Unfortunately, the circuit has significant magnetic field dependence, and therefore, most of the precision TDR measurements at low-temperatures were conducted in zero magnetic field. In this work, we describe the design of a setup for precision TDR measurements in a dilution refrigerator down to ~40 mK with a 14 T superconducting magnet. The key features of our design are the separated electronics components and the placement of the most field sensitive parts in the field-compensated zone far from the center of solenoid as well as the heat-sinking at a higher temperature stage. The performance of the working setup is demonstrated using several superconductors. PMID- 30278768 TI - The generation of mega-gauss fields on the Cornell beam research accelerator. AB - Intense magnetic fields modify quantum processes in extremely dense matter, calling for precise measurements in very harsh conditions. This endeavor becomes even more challenging because the generation of mega-gauss fields in a laboratory is far from trivial. This paper presents a unique and compact approach to generate fields above 2 MG in less than 150 ns inside a volume on the order of half a cubic centimeter. Magnetic insulation, keeping plasma ablation close to the wire surface, and mechanical inertia, limiting coil motion throughout the current discharge, enable the generation of intense magnetic fields where the shape of the conductor controls the field topology with exquisite precision and versatility, limiting the need for mapping magnetic fields experimentally. PMID- 30278769 TI - Amplifier for scanning tunneling microscopy at MHz frequencies. AB - Conventional scanning tunneling microscopy (STM) is limited to a bandwidth of a few kHz around DC. Here, we develop, build, and test a novel amplifier circuit capable of measuring the tunneling current in the MHz regime while simultaneously performing conventional STM measurements. This is achieved with an amplifier circuit including a LC tank with a quality factor exceeding 600 and a home-built, low-noise high electron mobility transistor. The amplifier circuit functions while simultaneously scanning with atomic resolution in the tunneling regime, i.e., at junction resistances in the range of giga-ohms, and down towards point contact spectroscopy. To enable high signal-to-noise ratios and meet all technical requirements for the inclusion in a commercial low temperature, ultra high vacuum STM, we use superconducting cross-wound inductors and choose materials and circuit elements with low heat load. We demonstrate the high performance of the amplifier by spatially mapping the Poissonian noise of tunneling electrons on an atomically clean Au(111) surface. We also show differential conductance spectroscopy measurements at 3 MHz, demonstrating superior performance over conventional spectroscopy techniques. Further, our technology could be used to perform impedance matched spin resonance and distinguish Majorana modes from more conventional edge states. PMID- 30278770 TI - Note: Simultaneous measurement of in-plane and out-of-plane displacement by using orthogonally polarized self-mixing grating interferometer. AB - In this paper, we present an orthogonally polarized self-mixing grating interferometer (SMGI) for simultaneous measurement of in-plane and out-of-plane displacements. The measurement ranges in both directions are limited only by the length of grating. The orthogonally polarized lights emitted from a birefringent He-Ne laser are separated and enter the grating at +/-1st-order Littrow angles. The diffraction beams re-enter the laser cavity and cause self-mixing interference. To differentiate the orthogonally polarized lights and obtain high resolution, phase modulation technique is introduced to extract phases from the orthogonally polarized SMGI signals. The measurement results show that the proposed system can reach a submicron accuracy in the experiment. This work provides a good way to achieve high precision two-dimensional displacement measurement with a robust system configuration. PMID- 30278772 TI - Calibration methods for the simultaneous measurement of the impulse, mass loss, and average thrust of a pulsed plasma thruster. AB - This paper presents calibration devices and methods for the measurement of electric thruster performance parameters using a seesaw-type thrust stand to measure the mass loss of solid propellant in a vacuum. In previous studies, impact hammers and electrostatic combs have been manufactured for the calibration of the thrust and impulse using seesaw-type thrust stands. However, these conventional devices rely on self-calibration, which means that the input delivered by the device in unknown, and must undergo a calibration process themselves. In this paper, the manufactured calibration devices successfully reproduced known impulses, thrusts, and mass losses in a vacuum. By reproducing known inputs based on known masses, the proposed calibration devices can omit the conventionally required self-calibration process. The calibration results showed linear relations between outputs and known inputs and agreed with the theoretical values to within an error of 10%. Additionally, the uncertainties of all known inputs were less than 1.5%. On the basis of these results, the average thrust, impulse, and mass loss were measured using a calibrated thrust stand for the first time. The cumulative impulses obtained from the measured impulse and average thrust agreed with each other to within an error of 5%. The error of the measured mass loss per 1000 shots with respect to the actual mass loss measured using an electronic balance ranged from 1% to 17%.

AB - The suite of neutron powder diffractometers at Oak Ridge National Laboratory (ORNL) utilizes the distinct characteristics of the Spallation Neutron Source and High Flux Isotope Reactor to enable the measurements of powder samples over an unparalleled regime at a single laboratory. Full refinements over large Q ranges, total scattering methods, fast measurements under changing conditions, and a wide array of sample environments are available. This article provides a brief overview of each powder instrument at ORNL and details the complementarity across the suite. Future directions for the powder suite, including upgrades and new instruments, are also discussed. PMID- 30278773 TI - An automated instrument for polarization-enhanced broadband nuclear quadrupole resonance (NQR) spectroscopy. AB - An automated instrument for improving the sensitivity of nuclear quadrupole resonance (NQR) spectroscopy is presented. The device is capable of pre polarizing samples within a custom Halbach-type permanent magnet and then moving them into an external probe for zero-field NQR detection. Polarization transfer between protons and nitrogen (14N) nuclei in the sample occurs during demagnetization, thus increasing the amplitude of the detected NQR signals. The sample motion profile is completely programmable, thus providing a high level of control over the sample position and velocity for optimizing the polarization transfer process for various samples. Moreover, the magnet and motion controller are combined with a shielded sample probe and ultra-broadband front-end electronics (both designed in-house) to realize a complete scientific instrument for 14N NQR experiments. Compared with previous work in the field, the system is designed to be programmable, robust, and easy to use. Experimental results from several samples are also presented. PMID- 30278774 TI - RHEGAL: Resistive heating gas enclosure loadframe for in situ neutron scattering. AB - In situ neutron scattering is a powerful tool to reveal materials atomic structural response such as phase transformation, lattice straining, and texture under external stimuli. The advent of a high flux neutron source such as the Spallation Neutron Source (SNS) allows fast measurement in even non-equilibrium conditions, i.e., phase transformation in steels. However, the commercial fast heating apparatus such as commercial physical simulation equipment is not designed for in situ neutron scattering, which limits its application to in situ materials research by using neutrons. Here we present a resistive heating gas enclosure loadframe (RHEGAL) for non-equilibrium phase transformation studies by using in situ neutron scattering, which takes the advantage of high flux neutron sources like SNS. RHEGAL enables fast resistive heating of metal samples to 1200 degrees C at a rate up to 60 degrees C/s in an inert atmosphere. It provides both horizontal and vertical positions for scattering optimization. The mechanical loading capability also allows in situ high temperature tension above the oxidation temperature limit. The optimized translucent neutron scattering window by silicon allows both reflection and transmission measurements, making this equipment applicable for neutron diffraction, small angle scattering, and imaging. To demonstrate the fast heating capability, the phase transformations of an example of advanced high strength steel heated at 3 degrees C/s and 30 degrees C/s were measured with the VULCAN engineering diffractometer, and the different phase transformation kinetics by neutron diffraction were presented. PMID- 30278775 TI - Glycoprotein VI Gene Variants Affect Pregnancy Loss in Patients With Platelet Hyperaggregability. AB - The aim of our study was to evaluate GP6 gene in patients with sticky platelet syndrome (SPS) and fetal loss. Platelet aggregability was tested with platelet rich plasma using PACKS-4 aggregometer (Helena Laboratories). High-resolution melting analysis on LightCycler 480 II (Roche Diagnostics) was used for single nucleotide polymorphism (SNP) genotyping. We examined 64 patients with SPS and 54 control participants. We found significantly higher occurrence of 5 SNPs in patients with SPS versus controls (rs1671152, rs1654433, rs1613662, rs1654416, and rs2304167). Moreover, the haplotype analysis showed a significantly higher occurrence of 7 haplotypes in patients with SPS compared to controls (acgg and aagg in GP6_5reg haplotype; ccgt in GP6_3reg haplotype; gg and ta in GP6_REG haplotype; SKTH and PEAN in GP6_PEAN haplotype). Our results, especially higher occurrence of 4 nonsynonymous variants within the coding region, support the idea that GP6 polymorphisms are associated with the platelet hyperaggregability accompanied by fetal loss. PMID- 30278776 TI - Venous Thromboembolism: A Survey of Oral Anticoagulant Preferences in the Treatment of Challenging Patient Populations. AB - Venous thromboembolism (VTE) is a highly morbid condition with several available oral anticoagulant treatment options. Numerous studies have been published comparing warfarin to direct oral anticoagulants; however, several populations remain underrepresented in these reports. We surveyed members of The Venous ThromboEmbolism Network U.S. working group regarding their oral anticoagulant preferences for the treatment of VTE in different and challenging populations. In individuals with VTE and no other medical comorbidities, respondents preferred either rivaroxaban (48.7%) or apixaban (48.7%). Apixaban (53.3%) was preferred in elderly individuals with an increased risk of bleeding. Warfarin was preferred in individuals with liver or kidney dysfunction (42% and 47%), altered metabolism (>55%), and antiphospholipid antibody syndrome (84.2%). Low-molecular-weight heparin was preferred in individuals with malignancy (56.6%), followed by edoxaban (23.7%). These findings may help guide clinicians when choosing an anticoagulant in these challenging situations and demonstrate the urgent need for additional study in these groups. PMID- 30278777 TI - Effect of Exercise on Behavioral Symptoms and Pain in Patients With Dementia Living in Nursing Homes. AB - OBJECTIVES: Examine the effects of a 6-month exercise intervention on neuropsychiatric symptoms, pain, and medication consumption in older people with dementia (PWD) living in nursing homes (NH). METHODS: Ninety-one older PWD living in NH performed a 6-month structured exercise intervention (n = 44) or a social activity intervention (n = 47). Neuropsychiatric symptoms were measured by the neuropsychiatric inventory (NPI), pain was assessed using the Algoplus scale, and dementia-related drug prescriptions were obtained for all participants. RESULTS: Between-group analysis found a nonsignificant difference that could be of clinical relevance: a 4-point difference in the NPI and 1.3-point difference in the reduction of the number of medications favoring exercisers. No significant differences were found for pain, and a trend was found for an increase in medication consumption in the social group. CONCLUSION: Exercise effects did not differ from social intervention effects on neuropsychiatric symptoms, pain, and medication consumption in older PWD living in NH. PMID- 30278778 TI - Effect of short-term mechanical stimulation on the salivary concentrations of vitamin C, vitamin E, total antioxidant capacity and total oxidant status. AB - Oxidative stress biomarkers of oral and systemic diseases can be found in saliva. However, there is no uniformity for the saliva collection time in these kinds of analyses and saliva composition may change because of mechanical stimulation. Therefore, the aim of this work was to determine the effect of mechanical stimulation for 10 min on the concentrations of vitamin C, vitamin E, total antioxidants and total oxidants in saliva. Saliva samples from individuals of both sexes, aged between 18 and 38 years, were collected for 10 min at 2 minintervals. Saliva flow rate in each 2 min period was measured, as well the total oxidant state, the total antioxidant capacity, vitamin C and vitamin E concentrations. All analyses were performed in triplicate and were determined using colorimetric tests. The results were analysed using t-test, Friedman's test and analysis of variance (ANOVA) for repeated measures. Mauchly's sphericity test was applied and, if necessary, technical corrections were made using the Greenhouse-Geisser test. We found no significant difference between the amounts of saliva produced across the collection times. Total oxidant status, total antioxidant capacity, vitamin C and vitamin E concentrations remained stable. Based on our findings, saliva can be collected for 10 min or less with masticatory stimulation without any variations in the concentration of the variables analysed. However, we suggest using saliva samples after two minutes of mechanical stimulation. PMID- 30278779 TI - Cytokines and statin therapy in chronic obstructive pulmonary disease patients. AB - Cytokines are biological response modifiers involved in the pathophysiology of chronic obstructive pulmonary disease (COPD). This study investigated the potential use of cytokines as disease severity biomarkers in COPD patients and the possible effect of statin therapy on cytokine expression. Possible associations between cytokines, body mass index (BMI) and smoking have also been studied. Cytokines IFN-gamma, IL-2, IL-12 p70, TNF-alpha, TNF-beta, IL-4, IL-5, IL-6, IL-10, IL-1beta and IL-8 were measured in the plasma of 100 clinically stable COPD patients using a fluorescent bead immunoassay on a flow cytometer. When patients were grouped according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage (A-D), no significant differences in cytokine concentrations were found (p > .05). Significantly decreased concentrations of IL 1beta, IL-2, IL-4, IL-8, IL-10, IL-12p70 and TNF-alpha were found in COPD patients receiving statin therapy in comparison with COPD patients not receiving statin therapy (p < .05). COPD patients with increased BMI (>25) had decreased IL 2 (p=.038), IL-8 (p = .039) and IL-10 (p = .005) concentrations compared to normal BMI (20-25) patients. Current COPD smokers had increased concentrations of IL-5 (p = .037) compared to former COPD smokers. Hierarchical cluster analysis showed several patterns of measured cytokines in serum of patients with stable COPD. Statin therapy is associated with decreased expression of selected Th1 and Th2 cytokines in COPD, and this effect could be of relevance in COPD patients with increased cardiovascular risk. Concentrations of Th1 and Th2 cytokines in plasma cannot be used as biomarkers of disease severity or progression of COPD. PMID- 30278780 TI - Comparative immunogenicity assessment of biosimilars. AB - The first anticancer biosimilars have entered clinical use, with many others under clinical development. Like all biologics, biosimilars may elicit unwanted immune responses that can significantly impact clinical efficacy and safety. Head to-head immunogenicity assessment of biosimilars and their reference biologics should, therefore, be a critical component of a biosimilar's clinical development program. Various bioanalytical platforms may be used to detect and characterize immune responses, each having relative strengths and weaknesses. To fully recognize the clinical relevance of such data, regulators must be able to interpret immunogenicity results in an assay-specific context as well as in perspective of clinical pharmacology, efficacy and safety. Herein, we discuss current challenges imposed by global regulatory requirements for immunogenicity assessment of biosimilars. PMID- 30278781 TI - Antioxidant and anti-inflammatory effects of pomegranate peel extracts on bovine mammary epithelial cells BME-UV1. AB - Pomegranate peel extracts (PPE) were tested for the first time on BME-UV1, a valid cellular model to study the bovine mammary epithelial metabolism, to evaluate the effects on the oxidative stress and inflammatory status. Based on the statistical analysis of MTT data, PPE at 0.1, 1.0 and 10 MUg/mL resulted not cytotoxic after 24 h, 48 h and 7 days of treatment. At the same concentrations, PPE induced a reduction of ROS production elicited by the addition of hydrogen peroxide or lipopolysaccharide evidencing an antioxidant effect confirmed also by a decrease of malondialdehyde. At 10 MUg/mL, PPE reduced pro-inflammatory cytokines expressions showing an anti-inflammatory effect on BME-UV1 treated with lipopolysaccharide. Although in vivo experiments are necessary, the results of this study are promising for future applications of PPE as feed supplement for dairy cattle, in particular around calving, when the animals are more subject to oxidative stress and inflammatory diseases. PMID- 30278782 TI - Accessing and Recruiting a Community-Based Sample of Men of Mexican Origin to Explore Intimate Partner Violence. AB - INTRODUCTION: Vulnerable populations are at greater risk for the burden of disease and negative health outcomes including alcohol abuse, high-risk sexual behavior, and intimate partner violence (IPV). Moreover, health disparities experienced by vulnerable populations are mediated by socioeconomic, ethnic, and racial factors. Risk factors for IPV perpetration are exacerbated by cultural and gender norms, particularly among men of Mexican origin. PURPOSE: To discuss research methods used in a community-based sample of men of Mexican origin and ways to overcome recruitment barriers through community engaged approaches. DISCUSSION: Barriers can impede sampling, recruitment, and enrollment of vulnerable populations (e.g., IPV) but can be overcome. Strategies include: qualitative research methods, identifying key informants, and community engagement approaches, such as listening to the concerns of the community, incorporating the community's knowledge to inform and improve the study, and building rapport to establish trust. CONCLUSION: Conducting research within vulnerable populations can be challenging but can be mitigated by incorporating multiple strategies. Thus, allowing researchers to gain access and valuable insight into traditionally underrepresented and understudied populations. PMID- 30278783 TI - Longitudinal study of medication use in caregivers of people with Alzheimer's disease - Kuopio ALSOVA study. AB - BACKGROUND: The longitudinal pattern of medication use among family caregivers of people with dementia is not well understood, despite the potential for medication over- or under-use. OBJECTIVES: To investigate caregiver medication use over a five-year follow-up using data obtained via self-report and from a national prescription register, and compare agreement between medication data obtained from the two sources. METHODS: Medication data for 222 family caregivers of people with Alzheimer's disease were obtained via self-report and from the Finnish Social Insurance Institution. Generalised estimating equations, Kappa statistics and related samples Wilcoxon signed rank test were used to analyse medication use over time. RESULTS: The mean number of medications used by caregivers increased from 3.4 to 4.1 (self-reported current regular medications) and 2.4 to 2.8 (reimbursed prescription medications during the past 90 days) over five years (p < 0.001). Significantly, more medications were identified via self report (mean 3.6, SD = 3.3) than the national prescription register (mean 2.6, SD = 2.4, Z= -12.300, p < 0.001). Agreement between the two data sources was good for cardiovascular medications and anti-hypertensives (Kappa = 0.883-0.967, p < 0.001) and medications for acid-related disorders (Kappa = 0.508-0.092, p < 0.001). Agreement was moderate for analgesics (Kappa = 0.281-0.477, p < 0.001) and psychotropics (Kappa = 0.281-0.562, p < 0.002). The proportion of caregivers using five or more medications increased from 27.5% to 44.6% (self-report), and 16.7% to 27.7% (register) (p < 0.001). CONCLUSION: Caregivers use an increasing number of medications in the first five years of caring for persons with dementia, and self-report using a higher number of medications than data from the national prescription register suggest. PMID- 30278784 TI - Assessment of Orthodontic Burden of Care in Patients With Unilateral Complete Cleft Lip and Palate. AB - OBJECTIVE: To assess the orthodontic burden of care of patients from a Brazilian rehabilitation center (Hospital for Rehabilitation of Craniofacial Anomalies, University of Sao Paulo [HRAC-USP]). DESIGN: Retrospective. SETTING: Hospital for Rehabilitation of Craniofacial Anomalies, University of Sao Paulo. INTERVENTIONS: One hundred files of unilateral complete cleft lip and palate patients who had consecutively finished orthodontic rehabilitation at HRAC-USP were evaluated from January 2011 to January 2013. The duration of orthodontic treatment, number of visits, kilometers traveled, number of appliances and surgical procedures performed were recorded. The sample was divided into 2 subgroups according to severity the interarch relation (Goslon Yardstick score) at the beginning of orthodontic treatment. Mann-Whitney test was applied for intergroup comparison ( P < .05). RESULTS: For the total sample (n = 100), the mean time of orthodontic treatment was 140.2 months, the mean number of orthodontic appointments was 61.8, the mean number of appliances was 10, the mean number of surgical procedures was 6.2, and the mean distance traveled to attend the center for orthodontic appointments was 38,978.5 km. The subgroup with the most severe malocclusion (Goslon yardsticks scores 4 and 5) showed a longer orthodontic treatment length, greater number of surgical procedures, and longer distance traveled than those presenting Goslon yardstick scores 1, 2, and 3. CONCLUSION: Patients with greater severity of the initial malocclusion experienced a higher burden of care than patients with less severity of the initial malocclusion. To reduce the burden of care, research and efforts should focus on minimizing maxillary growth deficiency related to primary surgery. PMID- 30278785 TI - Development of a core outcome set for trials investigating the long-term management of bronchiectasis. AB - Heterogeneity in outcomes measured in trials limits accurate comparison of bronchiectasis studies. A core outcome set (COS) is an agreed, standardized set of outcomes that should be measured in trials for specific clinical areas. A COS for bronchiectasis could encourage consistency in future studies. An overview of systematic reviews and qualitative study on outcome selection in bronchiectasis informed an initial list of outcomes. A Delphi panel ( n = 86) rated the importance of each outcome from 1 to 9 in 3 sequential questionnaires, as a means to achieve consensus: 1-3 = 'of limited importance'; 4-6 = 'important, but not critical'; and 7-9 = 'critical'. Outcomes rated 'critical' by >=70% of the panel were added to the COS. Eighty-two participants responded to the first questionnaire. Attrition between each questionnaire was 5%. After 3 rounds of questioning, 18 outcomes exceeded the threshold for consensus and were included in the COS. This study has achieved consensus on 18 outcomes that should be measured in trials of interventions for bronchiectasis. Selection of the highest ranked outcomes may represent a pragmatic means for comparison. Further research is required to condense the number of outcomes selected and to determine its relevance to interventions. PMID- 30278786 TI - Validation of electronic medical data: Identifying diabetes prevalence in general practice. AB - BACKGROUND: Electronic medical records are increasingly used for research with limited external validation of their data. OBJECTIVE: This study investigates the validity of electronic medical data (EMD) for estimating diabetes prevalence in general practitioner (GP) patients by comparing EMD with national Bettering the Evaluation and Care of Health (BEACH) data. METHOD: A "decision tree" was created using inclusion/exclusion of pre-agreed variables to determine the probability of diabetes in absence of diagnostic label, including diagnoses (coded/free-text diabetes, polycystic ovarian syndrome, impaired glucose tolerance, impaired fasting glucose), diabetic annual cycle of care (DACC), glycated haemoglobin (HbA1c) > 6.5%, and prescription (metformin, other diabetes medications). Via SQL query, cases were identified in EMD of five Illawarra and Southern Practice Network practices (30,007 active patients; from 2 years to January 2015). Patient based Supplementary Analysis of Nominated Data (SAND) sub-studies from BEACH investigating diabetes prevalence (1172 GPs; 35,162 patients; November 2012 to February 2015) were comparison data. SAND results were adjusted for number of GP encounters per year, per patient, and then age-sex standardised to match age-sex distribution of EMD patients. Cluster-adjusted 95% confidence intervals (CIs) were calculated for both datasets. RESULTS: EMD diabetes prevalence (T1 and/or T2) was 6.5% (95% CI: 4.1-8.9). Following age-sex standardisation, SAND prevalence, not significantly different, was 6.7% (95% CI: 6.3-7.1). Extracting only coded diagnosis missed 13.0% of probable cases, subsequently identified through the presence of metformin/other diabetes medications (*without other indicator variables) (6.1%), free-text diabetes label (3.8%), HbA1c result* (1.6%), DACC* (1.3%), and diabetes medications* (0.2%). DISCUSSION: While complex, proxy variables can improve usefulness of EMD for research. Without their consideration, EMD results should be interpreted with caution. CONCLUSION: Enforceable, transparent data linkages in EMRs would resolve many problems with identification of diagnoses. Ongoing data quality improvement remains essential. PMID- 30278788 TI - [Clinical profile of adolescents being treated for problematic internet use]. AB - OBJECTIVES: This study highlights the clinical profile of adolescents having consulted with an addiction treatment center (ATC) in Quebec for a problematic internet use (PIU) to develop knowledge about these specific clients and precisely target their needs relative to treatment. METHOD: The study was conducted with 80 adolescents between ages 14 and 17 (M = 15.59) who had consulted with an ACT for a PIU. Adolescents have participated in an interview documenting internet use patterns and their consequences, mental health disorder co-occurrence, and family and social relationships. RESULTS: The sample was constituted of 75 boys (93.8%) and 5 girls (6.3%), who spent an average of 55.8 hours (SD = 27.22) per week on internet for non-school or professional activities. Almost all of these youths (97.5%) presented a co-occurring mental health disorder, and more than 70% had seeked help last year for a psychological problem. Results show that 92.6% feel their internet use significantly hinders their family relationships, and 50% feel it impedes their social relationships. CONCLUSIONS: This study shows the multiple difficulties experienced by adolescents in need of a treatment for their PIU. The presence of co-occurring mental health disorders and relational difficulties among them underlines the need to develop and implement in ACTs integrated assessments and treatments that target not only online activities, but also all of life domains that can be affected by PIU. CLINICAL IMPLICATIONS: - PIU adolescents are mainly boys who report problematic use of video games. - Almost all young people who consult for PIU have comorbid mental health problems and difficulties in their relation. - The study highlights the need to offer to this clientele an integrated assessment and treatment services that target all areas of their lives who are likely to be affected, to contribute or maintain the PIU. LIMITATIONS: - This study was conducted with a convenience sample and the results are representative of young people who have visited a treatment center for addiction. The generalization of results to all adolescents with PIU is limited. - Considering that PIU are subject to cultural influence, the scope of this study is limited to populations living in a culture similar to that of Quebec and Canada. PMID- 30278787 TI - Effects of the oral, direct factor Xa inhibitor edoxaban on routine coagulation assays, lupus anticoagulant and anti-Xa assays. AB - Edoxaban is an oral direct factor Xa inhibitor for prophylaxis and treatment of thromboembolic disorders. The effects on common coagulation assays are clinically valuable information and in certain clinical situations a quick assessment of the anticoagulant is wanted. Our aim was to investigate the effect of edoxaban on routine coagulation methods and evaluate anti-Xa assays, commonly used for other direct factor Xa inhibitors, for estimation of the drug concentration. Edoxaban was spiked to plasma samples from healthy subjects in the concentration range 0 742 ug/L and analyzed using different reagents for activated partial thromboplastin time (APTT) and prothrombin time (PT). Assays for antithrombin, activated protein C resistance, lupus anticoagulant (LA) and chromogenic anti-Xa assays were also included. Edoxaban displayed similar effects in vitro to other oral direct Xa inhibitors. The concentration needed to double the coagulation time varied between assays and reagents; 539-758 ug/L for the APTT and between 329 and 2505 ug/L for the PT. Edoxaban gave false high antithrombin activities in assays based on Xa-inhibition. Two integrated assays for LA, both based on activation with dilute Russell's viper venom, displayed different results. Chromogenic anti-Xa assays displayed linear dose-response curves with edoxaban up to approximately 500 ug/L. In conclusion, therapeutic concentrations of edoxaban variably affect different coagulation assays, and even different reagents within an assay group. In comparison with other oral Xa-inhibitors, the in vitro effects of edoxaban were more similar to rivaroxaban than apixaban. For measurement of edoxaban concentration in plasma, it is possible to use the chromogenic anti-Xa assays. PMID- 30278789 TI - Electroencephalographic Biomarkers for Treatment Response Prediction in Major Depressive Illness: A Meta-Analysis. AB - OBJECTIVE:: Reducing unsuccessful treatment trials could improve depression treatment. Quantitative EEG (QEEG) may predict treatment response and is being commercially marketed for this purpose. The authors sought to quantify the reliability of QEEG for response prediction in depressive illness and to identify methodological limitations of the available evidence. METHOD:: The authors conducted a meta-analysis of diagnostic accuracy for QEEG in depressive illness, based on articles published between January 2000 and November 2017. The review included all articles that used QEEG to predict response during a major depressive episode, regardless of patient population, treatment, or QEEG marker. The primary meta-analytic outcome was the accuracy for predicting response to depression treatment, expressed as sensitivity, specificity, and the logarithm of the diagnostic odds ratio. Raters also judged each article on indicators of good research practice. RESULTS:: In 76 articles reporting 81 biomarkers, the meta analytic estimates showed a sensitivity of 0.72 (95% CI=0.67-0.76) and a specificity of 0.68 (95% CI=0.63-0.73). The logarithm of the diagnostic odds ratio was 1.89 (95% CI=1.56-2.21), and the area under the receiver operator curve was 0.76 (95% CI=0.71-0.80). No specific QEEG biomarker or specific treatment showed greater predictive power than the all-studies estimate in a meta regression. Funnel plot analysis suggested substantial publication bias. Most studies did not use ideal practices. CONCLUSIONS:: QEEG does not appear to be clinically reliable for predicting depression treatment response, as the literature is limited by underreporting of negative results, a lack of out-of sample validation, and insufficient direct replication of previous findings. Until these limitations are remedied, QEEG is not recommended for guiding selection of psychiatric treatment. PMID- 30278790 TI - A Population-Based Analysis of the Relationship Between Substance Use and Adolescent Cognitive Development. AB - OBJECTIVE:: Alcohol and cannabis misuse are related to impaired cognition. When inferring causality, four nonexclusive theoretical models can account for this association: 1) a common underlying vulnerability model; 2) a neuroplasticity model in which impairment is concurrent with changes in substance use but temporary because of neuroplastic brain processes that restore function; 3) a neurotoxicity model of long-term impairment consequential to substance use; and 4) a developmental sensitivity hypothesis of age-specific effects. Using a developmentally sensitive design, the authors investigated relationships between year-to-year changes in substance use and cognitive development. METHOD:: A population-based sample of 3,826 seventh-grade students from 31 schools consisting of 5% of all students entering high school in 2012 and 2013 in the Greater Montreal region were assessed annually for 4 years on alcohol and cannabis use, recall memory, perceptual reasoning, inhibition, and working memory, using school-based computerized assessments. Multilevel regression models, performed separately for each substance, were used to simultaneously test vulnerability (between-subject) and concurrent and lagged within-subject effects on each cognitive domain. RESULTS:: Common vulnerability effects were detected for cannabis and alcohol on all domains. Cannabis use, but not alcohol consumption, showed lagged (neurotoxic) effects on inhibitory control and working memory and concurrent effects on delayed memory recall and perceptual reasoning (with some evidence of developmental sensitivity). Cannabis effects were independent of any alcohol effects. CONCLUSIONS:: Beyond the role of cognition in vulnerability to substance use, the concurrent and lasting effects of adolescent cannabis use can be observed on important cognitive functions and appear to be more pronounced than those observed for alcohol. PMID- 30278791 TI - Impaired Motion Processing in Schizophrenia and the Attenuated Psychosis Syndrome: Etiological and Clinical Implications. AB - OBJECTIVE:: The ability to perceive the motion of biological objects, such as faces, is a critical component of daily function and correlates with the ability to successfully navigate social situations (social cognition). Deficits in motion perception in schizophrenia were first demonstrated about 20 years ago but remain understudied, especially in the early, potentially prodromal, stages of the illness. The authors examined the neural bases of visual sensory processing impairments, including motion, in patients with schizophrenia (N=63) and attenuated psychosis (clinical high risk) (N=32) compared with age-matched healthy control subjects (N=67). METHOD:: Electrophysiological recordings during stimulus and motion processing were analyzed using oscillatory (time frequency) approaches that differentiated motion-onset-evoked activity from stimulus-onset sensory-evoked responses. These were compared with functional MRI (fMRI) measures of motion processing. RESULTS:: Significant deficits in motion processing were observed across the two patient groups, and these deficits predicted impairments in both face-emotion recognition and cognitive function. In contrast to motion processing, sensory-evoked stimulus-onset responses were intact in patients with attenuated psychosis, and, further, the relative deficit in motion-onset responses compared with stimulus-onset responses predicted transition to schizophrenia. In patients with schizophrenia, motion detection deficits mapped to impaired activation in motion-sensitive visual cortex during fMRI. Additional visual impairments in patients with schizophrenia, not present in patients with attenuated psychosis, implicated other visual regions, including the middle occipital gyrus and pulvinar thalamic nucleus. CONCLUSIONS:: The study findings emphasize the importance of sensory-level visual dysfunction in the etiology of schizophrenia and in the personal experience of individuals with the disorder and demonstrate that motion-processing deficits may predate illness onset and contribute to impaired function even in patients with attenuated psychosis. PMID- 30278792 TI - Intellectual Disability and Psychotic Disorders in Children: Association With Maternal Severe Mental Illness and Exposure to Obstetric Complications in a Whole Population Cohort. AB - OBJECTIVE:: Children of mothers with severe mental illness are at significantly increased risk of developing intellectual disability. Obstetric complications are also implicated in the risk for intellectual disability. Moreover, children of mothers with severe mental illness are more likely to be exposed to obstetric complications. The purpose of this study was to examine the independent and joint contributions of familial severe mental illness and obstetric complications to the risk of intellectual disability. METHOD:: Record linkage across Western Australian whole-population psychiatric, inpatient, birth, and midwives' registers identified 15,351 children born between 1980 and 2001 to mothers with severe mental illness and 449,229 children born to mothers with no mental illness. Multivariable models were adjusted for paternal psychiatric status, parental intellectual disability, and other family and sociodemographic covariates. RESULTS:: The risk of intellectual disability was increased among children of mothers with severe mental illness compared with children of unaffected mothers. The impact varied across maternal diagnostic groups. For children of mothers with schizophrenia, the unadjusted odds ratio was 3.8 (95% CI=3.0, 4.9) and remained significant after simultaneous adjustment for exposure to obstetric complications and other covariates (odds ratio=1.7, 95% CI=1.3, 2.3). The odds ratio for exposure to obstetric complications also remained significant after adjustment (odds ratio=1.7, 95% CI=1.6, 1.8). For intellectual disability of a genetic basis, the adjusted odds ratio for maternal schizophrenia was elevated but not statistically significant. Among children with intellectual disability, 4.2% later developed a psychotic disorder, compared with 1.1% of children without intellectual disability. CONCLUSIONS:: Maternal severe mental illness and exposure to obstetric complications contribute separately to the risk of intellectual disability, suggesting potentially different causal pathways. PMID- 30278793 TI - Cross-cultural adaptation and validation of the ABIS questionnaire for French speaking amputeesFrench validation of the ABIS questionnaire. AB - BACKGROUND: The Amputee Body Image Scale (ABIS) and its shortened version (ABIS R) are self-administered questionnaires to measure body image perception of amputee. Our aim was to assess the validity and reliability of the French ABIS (ABIS-F and ABIS-R-F). METHODS: Ninety-nine patients were included. The cross cultural adaptation was performed according to the recommendations. Construct validity was assessed by measuring the correlation between ABIS-F or ABIS-R-F scores and quality of life, pain, anxiety, and depression. Internal consistency was measured with Cronbach's alpha. The standard error of measurement, smallest detectable change, Bland and Altman limits of agreement, and intraclass correlation were the measures of agreement and reliability. RESULTS: A highest body image disturbance was associated with lowest quality of life, higher pain, and higher anxiety, and depression. Cronbach's alpha was 0.91/0.89 (ABIS-F/ABIS-R F). The standard error of measurement was 5.35/2.28 (ABIS-F/ABIS-R-F). The smallest detectable change was 14.82/6.31 (ABIS-F/ABIS-R-F). The mean difference in ABIS-F score was -3.90 with limits of agreement from -18.71 to 10.92. For ABIS R-F, the mean difference was -2.12 with limits of agreement from -8.43 to 4.19. Intraclass correlation was 0.87/0.82 (ABIS-F/ABIS-R-F). CONCLUSIONS: The French versions ABIS-F and ABIS-R-F share similar psychometric properties, both are as reliable, but ABIS-R-F has a better response structure and is more feasible. Implications for rehabilitation The quality of life of amputees is impacted by their satisfaction with body image The Amputee Body Image Scale questionnaire measures this perception and is available for French-speaking amputees The Standard Errors of Measurement proposed could be useful for clinical and research purposes Both ABIS and ABIS-R showed satisfactory construct validity, internal consistency, and reliability The shortened version has a better response structure and is more readily feasible. PMID- 30278794 TI - Care coordinator assistants: Job satisfaction and the importance of teamwork in delivering person-centered dementia care. AB - As the prevalence of persons with dementia increases, a larger, trained, and skilled healthcare workforce is needed. Attention has been given to models of person-centered care as a standard for dementia care. One promising role to deliver person-centered care is the care coordinator assistant. An inquiry about care coordinator assistant's job satisfaction is reasonable to consider for retention and quality improvement purposes. We evaluated care coordinator assistants' job satisfaction quantitatively and qualitatively. This study was part of a Centers for Medicare & Medicaid Services Health Care Innovation Award to the Indiana University School of Medicine. Sixteen care coordinator assistants, predominately female, African American or Caucasian, college graduates with a mean age of 43.1 years participated. Care coordinator assistants wrote quarterly case reports to share stories, lessons learned, and/or the impact of their job and completed the revised Job Satisfaction Inventory and Job in General scales during the second year of the Centers for Medicare & Medicaid Services award. For the Job Descriptive Index subscales promotion, supervision, and coworkers and Job in General, care coordinator assistants scored similar to normative means. Care coordinator assistants reported significantly higher satisfaction on the work subscale and significantly lower satisfaction on the pay subscale compared to normative data. Care coordinator assistants completed 119 quarterly case reports. Job satisfaction and teamwork were recurring themes in case reports, referenced in 47.1% and 60.5% of case reports, respectively. To address the demands of increasing dementia diagnoses, care coordinator assistants can constitute a compassionate, competent, and satisfied workforce. Training care coordinator assistants to work together in a team to address the needs of persons with dementia and caregivers provides a viable model of workforce development necessary to meet the growing demands of this population. PMID- 30278795 TI - Clinical characteristics and prognosis of idiopathic pulmonary hemosiderosis in pediatric patients. AB - Objective This study aimed to analyze the clinical characteristics and prognosis of pediatric idiopathic pulmonary hemosiderosis (IPH). Methods Pediatric IPH cases that were diagnosed at West China Second University Hospital, Sichuan University between 1996 and 2017 were reviewed. Follow-up data from 34 patients were collected. Results A total of 107 patients were included (42 boys and 65 girls). The median age was 6 years at diagnosis. The main manifestations of the patients were as follows: anemia (n = 100, 93.45%), cough (n = 68, 63.55%), hemoptysis (n = 61, 57%), fever (n = 23, 21.5%), and dyspnea (n = 23, 21.5%). There were relatively few pulmonary signs. The positive rates of hemosiderin laden macrophages in sputum, gastric lavage fluid, and bronchoalveolar lavage fluid were 91.66%, 98.21%, and 100%, respectively. Seventy-nine patients were misdiagnosed. A total of 105 patients were initially treated with glucocorticoids, among whom 102 survived and three died. Among the followed up patients, two died and 32 survived, among whom 10 presented with recurrent episodes. Conclusions The classic triad of pediatric IPH is not always present. The rates of misdiagnosis and recurrence of IPH are high. Early recognition and adequate immunosuppressive therapy are imperative for improving prognosis of IPH. PMID- 30278796 TI - Serum NGAL and FGF23 may have certain value in early diagnosis of CIN. AB - AIMS: This study aimed to assess whether neutrophil gelatinase-associated lipocalin (NGAL) and fibroblast growth factor 23 (FGF23) could be reliable biomarkers for early diagnosis of contrast-induced nephropathy (CIN). METHODS: 202 patients who underwent percutaneous coronary intervention (PCI) were included in the research. All subjects were divided into CIN group and non-CIN group. Serum NGAL and FGF23 were evaluated before and 0, 1, and 2 days after PCI. Serum levels of these two markers were compared intra-group and among groups. Receiver operating characteristic (ROC) analysis and logistic regression models were conducted to assess the diagnostic performance of NGAL and FGF23 in detecting CIN. RESULTS: When compared with baseline values, serum levels of both NGAL and FGF23 in all subjects increased after PCI, and the values peaked 1 day after PCI, but the changing was greater in CIN group. There were obvious differences between two groups in serum NGAL after 1, 2 days, and similar differences present in serum FGF23 after 1 day. ROC analysis showed that the area under the curve (AUC) of relative values (percent change from the baseline) in NGAL after 1 day was 0.899 (95% CI: 0.834-0.964, p = .000), the optimum cutoff was 49% (sensitivity = 80%, specificity = 92.4%). And the AUC in FGF23 was 0.814 (95% CI: 0.733-0.894, p = .000), the optimum cutoff was 20% (sensitivity = 73.3%, specificity = 87.6%). Both serum NGAL and serum FGF23 could improve the clinical models in identifying CIN. CONCLUSIONS: NGAL and FGF23 may have certain value in early diagnosis of CIN. PMID- 30278797 TI - Clinical and pathologic characteristics of pauci-immune anti-myeloperoxidase antibody associated glomerulonephritis with nephrotic range proteinuria. AB - BACKGROUND: Heavy proteinuria in antineutrophil cytoplasmic antibody (ANCA) associated glomerulonephritis (GN) is usually considered to be associated with immune deposits in renal biopsy. Nephrotic ANCA GN without immune deposits (pauci immune) is rare and has not been studied specially. In this study characteristics of these patients are to be investigated. METHODS: Clinical and pathological characteristics from 20 kidney biopsy-proven pauci-immune anti-myeloperoxidase antibody-associated GN patients with nephrotic proteinuria were analyzed and were compared with ANCA GN patients without nephrotic proteinuria. RESULTS: Acute kidney injury (AKI) and gross hematuria were much prevalent but extra-renal involvement was less prevalent in pauci-immune ANCA GN with nephrotic proteinuria than in pauci-immune ANCA GN without nephrotic proteinuria. No more severe hypoalbuminemia, hypercoagulability, hyperlipidemia or higher thrombosis incidence were found between two groups. Compared with patients without nephrotic proteinuria, patients with nephrotic proteinuria had more prevalent crescentic category in histopathology. Proteinuria decreased quickly after treatment but much poorer renal prognosis was found in pauci-immune ANCA GN with nephrotic proteinuria. The results of urinary albumin to total protein ratio and urinary protein electrophoresis showed pauci-immune ANCA GN with nephrotic proteinuria had obvious non-selective proteinuria. CONCLUSIONS: Pauci-immune ANCA GN with nephrotic proteinuria do not have more severe hypoalbuminemia, hypercoagulability or hyperlipidemia than patients without nephrotic proteinuria. Non-selective proteinuria might be the reason. However, pauci-immune ANCA GN with nephrotic proteinuria have more prevalent crescentic category in histopathology, higher incidence of AKI, gross hematuria and poorer renal prognosis despite of good sensitivity to therapy of proteinuria. PMID- 30278798 TI - Glycogen synthase kinase (GSK) 3 in pregnancy and parturition: a systematic review of literature. AB - INTRODUCTION: Human reproduction is a multifaceted process reliant on proper blastocyst implantation, placental and fetal membrane development, and delivery of a healthy baby. Multiple factors and pathways have been reported as critical machineries for cell differentiation and survival during pregnancy, and most of them involve glycogen synthase kinase (GSK) 3alpha/beta for cell differentiation and survival and for maintaining cellular homeostasis. Several reports on GSK3's functional role exist; however, the specific role of GSK3 in reproductive tissues and its contribution to normal or abnormal parturition are still unclear. To fill this knowledge gap, a systematic review of literature was conducted to better understand the functional role of GSK3 in various intrauterine tissues during implantation, pregnancy, and parturition. METHODS: We conducted a systematic review of English literature published between 1980 and 2017 on GSK3's expression and function reported in reproductive tissues during pregnancy using 3 electronic databases (Web of Science, Medline, and ClinicalTrials.gov). Study selection, data extraction, and quality assessment were performed in duplicate by two independent reviewers. RESULTS: A total of 738 citations were identified; 80 were selected for full text evaluation and 25 were included for final review. GSK3's regulation and function were mostly studied in tissues and cells from placentas (12), fetuses (8), uteruses (6), and ovaries (2). Measurements of total GSK3 and its isoforms (alpha and/or beta) were determined mostly by Western blot analysis. GSK3 is primarily reported as a downstream responder of protein kinase B (AKT)-, Wnt-, and reactive oxygen species (ROS)-related pathways where it plays a critical role in cell survival and growth in reproductive tissues. CONCLUSIONS: GSK3 is functionally linked to blastocyst implantation, establishment of pregnancy, trophoblast migration and invasion, decidualization, and term and preterm labor. Few reports specifically studied GSK3's expression and function in any reproductive tissues; it has mostly been studied as a secondary signaler of various conserved cell signaling pathways. Lack of scientific rigor in studying GSK3's role in reproductive tissues makes this molecule's function still obscure. No studies have reported GSK3 in the cervix, and very few reports exist in myometrium and decidua. GSK3's functions are hardly studied in reproductive tissues, and several knowledge gaps have been identified that require more functional studies in reproductive biology. PMID- 30278799 TI - Maternal age and cardiovascular and metabolic disease outcomes: A retrospective cohort study using data from population-based electronic medical records. AB - OBJECTIVE: To evaluate whether a woman's age at first birth is associated with cardiovascular risk and metabolic health outcomes (cardiometabolic outcomes) by age 45. METHODS: This is a retrospective, population-based cohort study that uses electronic health record data from the largest health fund in Israel. Women aged 34-39 at baseline (2004-2006) free of chronic diseases were identified as nulliparous at baseline and were followed up to 10 years (through 2016). The cohort was divided into three groups based on their age at first birth: younger parturients (ages 35-39), older parturients (ages 40-44), and never had children. The percentage of adverse pregnancy events and cardiometabolic outcomes at age 45 were compared across these three groups as well as to women in the general population. Cardiovascular risk and metabolic health outcomes were defined as: Type 2 diabetes, obesity, hypertension, cardiovascular disease, and Framingham risk score. METHODS AND RESULTS: Out of a group of 126 121 women aged 34-39 at baseline, 9979 were nulliparous and free of comorbidities. Over the course of the follow-up, there were 952 younger parturients and 673 older parturients who had their first birth, and 8354 women who remained persistent nulliparous. While older parturients had more adverse pregnancy events, there was no difference in rates of cardiometabolic outcomes between the two parturient groups, and they both had lower rates than the persistent nulliparous and the general population. CONCLUSIONS: Parturients free of major chronic diseases who give birth at a later age do not have increased cardiometabolic outcomes in midlife as compared to a general population of women in a large retrospective cohort. Our results may support clinicians when counseling healthy women who are seeking advice regarding delaying their first pregnancy without a tradeoff on health outcomes. PMID- 30278801 TI - Red blood cells as an organ? How deep omics characterization of the most abundant cell in the human body highlights other systemic metabolic functions beyond oxygen transport. AB - INTRODUCTION: Recently, the classification of two 'novel' organs, the mesentere and interstitium, was saluted as a scientific breakthrough and disseminated into mainstream media. The novelty of these findings did not pertain to the characterization of some previously unexplored phenomena, rather to the appreciation that well-established tissues may play some hitherto unexplored functions critical to system homeostasis. Areas covered: Here we provocatively comment on the potential classification of red blood cells - by far the most abundant host cell in the human body (~ 83% of the total cells) - as an organ involved in many functions beyond gas transport. In this perspective article, we describe some of these functions with a special emphasis on the role erythrocytes play with respect to systemic metabolic homeostasis. We thus focus on how these functions modulate the cross talk of red blood cells among each other and with other cell types including immune cells. Expert commentary: The appreciation of RBCs as an organ impacting systemic metabolic homeostasis and other cell functions while engaging in complex metabolic activity beyond oxygen transport can foster the development of novel therapeutic interventions in pathologic hypoxemia, inflammation, neurodgenerative diseases, aging, and cancer. PMID- 30278802 TI - Emicizumab for hemophilia A with factor VIII inhibitors. AB - INTRODUCTION: Hemophilia is a serious bleeding disorder characterized by repeated bleeding episodes into joints and muscles which can lead to permanent disabilities. Treatment with factor replacement therapy has proven to be effective at preventing these complications; however, it can lead to formation of neutralizing antibodies termed inhibitors which significantly complicate the management of the disorder. These inhibitor patients suffer from increased morbidity and mortality and there has been a major unmet need for novel therapeutic approaches. Recently, one such therapy, emicizumab, has been licensed in the United States. Areas covered: This manuscript contains a detailed discussion of the mechanism of action, the clinical trial development program as well as a review of the benefits and risks of this novel agent. In addition, practical considerations for the use of the agent are also described. Expert commentary: Emicizumab represents a new class of medication for the treatment of hemophilia A which in the past has relied on factor replacement therapy and bypassing agent (alternative factor) therapy. Emicizumab fulfills two major unmet needs in patients with hemophilia who have FVIII inhibitors. First, it provides for a much more effective therapy for the prevention of bleeding and second it substantially reduces the treatment burden. PMID- 30278803 TI - Mediating role of caregiver burden among family caregivers of patients with Parkinson's disease in Mexico. AB - Objective This study examined the mediating role of caregiver distress on family factors and caregiver life satisfaction among an understudied population of Parkinson's disease caregiver in Mexico. Methods A cross-sectional design was used to examine psychosocial factors pertinent to caregiver of individuals with Parkinson's disease ( n = 95). Guided by a caregiver stress process model, relations among family factors (e.g., cohesion, flexibility, quality of functioning), gender, distress, and satisfaction with life among caregiver were examined. Mediation analyses were performed to test the role of caregiver distress on the associations between family factors, gender, and caregiver satisfaction with life. Results Mediation models demonstrated that caregiver distress fully mediated the relation between quality of family functioning and caregiver satisfaction with life and partially mediated the association between family flexibility and caregiver satisfaction with life. Caregiver gender did not emerge as a significant covariate, and null results were found in the model examining family cohesion as a predictor. Conclusion These results underscore the critical role of caregiver distress and family factors on features of caregiver well-being, notably satisfaction with life. This evidence also offers cross cultural evidence for the caregiver stress process model, which has primarily been observed in Western samples. Accordingly, the need to build and disseminate empirically supported family-based treatments that emphasize caregiver distress is warranted.

AB - INTRODUCTION: Chymase is primarily found in mast cells (MCs), fibroblasts, and vascular endothelial cells. MC chymase is released into the extracellular interstitium in response to inflammatory signals, tissue injury, and cellular stress. Among many functions, chymase is a major extravascular source for angiotensin II (Ang II) generation. Several recent pre-clinical and a few clinical studies point to the relatively unrecognized fact that chymase inhibition may have significant therapeutic advantages over other treatments in halting progression of cardiac and vascular disease. Area covered: The present review covers patent literature on chymase inhibitors for the treatment of cardiac diseases registered between 2010 and 2018. Expert opinion: Increase in cardiac MC number in various cardiac diseases has been found in pathological tissues of human and experimental animals. Meta-analysis data from large clinical trials employing angiotensin-converting enzyme (ACE) inhibitors show a relatively small risk reduction of clinical cardiovascular endpoints. The disconnect between the expected benefit associated with Ang II blockade of synthesis or activity underscores a greater participation of chymase compared to ACE in forming Ang II in humans. Emerging literature and a reconsideration of previous studies provide lucid arguments to reconsider chymase as a primary Ang II forming enzyme in human heart and vasculature. PMID- 30278805 TI - Association between renal damage markers and carotid atherosclerosis in Afro descendants with hypertension belonging to a minority ethnic group from Brazil. AB - Ethnicity appears to play an important role in the prevalence and severity of hypertension, renal disease, and atherosclerosis. A cross-sectional study was conducted, including 206 Afro-descendants with hypertension, living in the remaining quilombo communities. These subjects underwent a carotid intima-media thickness (CIMT) assessment. The presence of renal injury was assessed by: (1) The glomerular filtration rate (GFR) estimated by the formula CKD-EPI using creatinine and cystatin C and (2) Albuminuria (ACR >=30 mg/g). The Poisson distribution model was set with robust variance to identify factors associated with carotid atherosclerosis. The statistical analysis was performed using the Stata 12.0 software, adopting a significance level of 5%. Most subjects were women (61.65%); the average age was 61.32 (+/-12.44) years. Subjects (12.62%) were identified with GFR <60 mL/min/1.73 m2 and 22.8% with albuminuria. Patients (59.22%) presented with a high CIMT. In the adjusted regression model, age >=60 years (PR: 1.232 [CI 95%:1.091-1.390], p value = .001), ACR >=30 mg/g (PR: 1.176 [CI 95%: 1.007-1.373], p = .040), and GFR/CKD-EPI using cystatin C (PR: 1.250 [CI 95%: 1.004-1.557], p = .045) were independently associated with carotid atherosclerosis. The occurrence of atherosclerotic lesions was high in the studied group. Age, albuminuria, and GFR (estimated by the formula CKD-EPI using cystatin C) influenced the prevalence of carotid atherosclerosis. PMID- 30278806 TI - Anterior humeral approach with nerve stimulator. AB - INTRODUCTION: The prevalence of radial nerve injury during surgery is as high as the prevalence of radial nerve injury due to trauma. The aim of this study is to minimize the risk of iatrogenic injury of radial nerve. MATERIALS AND METHODS: Fifty patients with middle or distal diaphysis fractures of humerus and 18 patients with pseudoarthrosis at the same localizations were treated with surgery. Plate-screw fixation was performed with anterior approach in 43 patients. Eleven patients had minimally invasive plate osteosynthesis, and 14 patients had intramedullary nailing. The localization of the radial nerve was determined with nerve stimulator at the area of dissection. RESULTS: Iatrogenic radial nerve injury did not occur in patients treated with open reduction or minimally invasive approach. DISCUSSION: Nerve stimulator may be a method that decreases radial nerve injury, an iatrogenic complication. This method may be used in anterior approach and minimally invasive procedures.

AB - The first population-based cohort study in Uppsala with the aim to study cardiovascular disease was initiated in 1970 (ULSAM). This cohort of 2300 middle aged men has since then been followed in a longitudinal fashion for almost 50 years. This study has been followed by the PIVUS study, investigating 1000 men and women at ages 70, 75, and 80. A very detailed examination has also been performed in 500 subjects aged 50 years, the POEM study. In recent years, a high throughput study conducted in 13000 subjects has also been performed, named EpiHealth. Uppsala also collects data in 5,000 subjects in the nationwide SCAPIS study. Taken together, these cardiovascular-oriented studies constitute a very rich source for cardiovascular epidemiological research in Uppsala. This review summarizes the design of these studies and highlights some of the important results published based on data from these studies.

PMID- 30278809 TI - A three-dimensional virtual morphometry study of the sigmoid notch of the distal radius. AB - PURPOSE: Our primary objectives were to create a reliable, noninvasive method for three-dimensional morphometry of deep bony parameters within the sigmoid notch of the distal radius, to identify its morphological patterns, and to identify any significant variation between the left and the right wrists. Our secondary objectives were to obtain morphometric values that could represent our population and to identify any possible ethnic variations. METHODS: Computed tomography scans of 102 wrists from 51 healthy individuals were analyzed using a virtualization software. Four anatomical parameters at the distal radius sigmoid notch, namely, the radius of curvature, depth, version angle, and sagittal slope were measured. Morphological patterns of the sigmoid notch surface were identified. The results were statistically analyzed to assess the reliability of the technique and were compared with previously published literature. RESULTS: Comparing our findings with previously published values, our study revealed a slightly larger radius of curvature and sagittal slope, while revealing a smaller depth and version. We identified the S-type, C-type, and ski-slope morphological variants. The flat-face morphological variant, however, was not identified. The sigmoid notch at the left and right wrists were similar, except for the radius of curvature. CONCLUSION: This study demonstrates a noninvasive, fast, reliable, and reproducible technique for analyzing the sigmoid notch of the distal radius. In wrist injuries with intact distal radius sigmoid notch but involving comminuted fractures of the ulnar head, ulnar head replacement may be indicated. In such cases, analysis of the ipsilateral intact sigmoid notch would allow us to prepare an ulnar head prosthesis of appropriate size.

Though several studies have examined the influence of stress on how young adults learn new information, the present study is the first to directly examine these effects in older adults. Fifty older adults (M age = 71.9) were subjected to either stress induction or a control task before learning two types of information: a short video and a series of pictures. Twenty-four hours later, they were exposed to misleading information about the video and then completed memory tests for the video and pictures. Heart rate and cortisol measures suggest that a physiological stress response was successfully induced. Though pre encoding stress had little impact on memory accuracy, stress did influence errors of omission on the cued recall test for the video. Findings are discussed in the context of previous research examining the effects of stress on memory in older adults. PMID- 30278811 TI - Evaluation of pre- and post-dilution continuous veno-venous hemofiltration on leukocyte and platelet function in patients with sepsis. AB - OBJECTIVE: We investigated the differences in biocompatibility pre- and post dilution during continuous veno-venous hemofiltration in patients with sepsis, focusing on leukocyte and platelet function. PATIENTS AND METHODS: Subjects were 12 patients with septic shock who underwent veno-venous hemofiltration for acute kidney injury between March 2016 and September 2017. The first six patients received pre-dilution veno-venous hemofiltration, and the next six patients received post-dilution veno-venous hemofiltration. The blood flow rate and filtration flow rate for veno-venous hemofiltration using a polysulfone hemofilter were set to 150 and 35 mL/min, respectively. Leukocyte and platelet counts were determined at 0 and 24 h after veno-venous hemofiltration commencement. Serum interleukin-6 and interleukin-10 levels, the induction rates of regulatory T cells, the expression rate of monocyte HLA-DR, neutrophil phagocytic and sterilizing ability, and platelet P-selectin expression rate were determined at 0, 6, and 24 h after veno-venous hemofiltration commencement. RESULTS: There were no significant differences in patient characteristics between the two groups. Serum interleukin-6 decreased over time during pre- and post dilution veno-venous hemofiltration. Serum interleukin-10 levels decreased during pre-dilution veno-venous hemofiltration, but remained unchanged during post dilution veno-venous hemofiltration. The Treg and platelet P-selectin expression rates significantly increased at 24 h compared to 0 h during post-dilution veno venous hemofiltration. Neutrophil phagocytic ability at 24 h was significantly decreased compared to that at 0 h during post-dilution veno-venous hemofiltration. No significant changes in leukocyte and platelet function were observed during pre-dilution veno-venous hemofiltration. CONCLUSION: Pre-dilution veno-venous hemofiltration demonstrates superior biocompatibility in terms of decreased leukocyte function and platelet activation in septic shock patients with acute kidney injury.

AB - AIM: The primary objective of this review is to provide an updated, comprehensive overview on the efficacy of intranasal fentanyl (INF) for acute pain relief in the pediatric population. METHODS: Utilizing the Preferred Reporting Instructions for Systematic Reviews and Meta-Analyses (PRISMA), we were able to screen articles based on key words to reach a final number of 10 studies. RESULTS: All but one study showed that INF was efficacious for pain relief in this select pediatric population. CONCLUSION: It is evident that INF is efficacious for analgesia, but other agents should also be considered in this patient population. As a result, further research is needed to investigate the clinically efficacy of INF in an acute care setting for pediatric patients. PMID- 30278813 TI - Carfilzomib Induced Tumor Lysis Syndrome and Other Adverse Events. AB - In the area of multiple myeloma (MM) therapy, proteasome inhibitors (PI) have emerged with promising responses both in the first- and second-line setting. Carfilzomib (CFZ) is a second-generation, selective PI approved in 2012 for the treatment of relapsed/refractory multiple myeloma (RRMM) in patients who received 2 prior therapies or have evidence of disease progression within 60 days of completion of last therapy. Its safety profile reported adverse events (AEs) ranging from drug-related AEs (nausea and vomiting), hematologic AEs (neutropenia and thrombocytopenia), and nonhematologic AEs (electrolyte imbalances). As CFZ use is gaining popularity, various hematological, renal, cardiovascular, pulmonary, and neurological toxicities have been reported. We are presenting this case to describe a rare occurrence of tumor lysis syndrome (TLS) with the use of this novel targeted therapy. PMID- 30278814 TI - Shock Index-A Useful Noninvasive Marker Associated With Age-Specific Early Mortality in Children With Severe Sepsis and Septic Shock: Age-Specific Shock Index Cut-Offs. AB - BACKGROUND: Aim of the study was to analyze the association of shock index (SI) from 0 to 6 hours with early mortality in severe sepsis/septic shock and to explore its age-specific cut-off values. To investigate association of change in SI over first 6 hours with early mortality. METHODS: A prospective cohort study of children (<14 years) admitted in emergency department, tertiary care hospital with severe sepsis or septic shock, divided into 3 groups: group 1: 1 month to <1 year; group 2: 1 to <6 years; group 3: 6 to 12 years. Shock index (SI = heart rate/systolic blood pressure) measured at admission (X0) and hourly till 6 hours (X1-6). Primary outcome was death within 48 hours of admission. Area under receiver operating characteristic curves were constructed for SI (0-6). Optimal cut-offs of SI 0 and SI 6, maximizing both sensitivity and specificity were determined and positive and negative predictive values (PPV, NPV) were calculated. RESULTS: From 2015 to 2016, 120 children were recruited. Septic shock was present at admission in 56.7% children. Early mortality was 50%. All hourly shock indices (SI 0-6) were higher among nonsurvivors in group 2 ( P <= .03) and group 3 ( P < .001). In group 1, SI after 2 hours was higher in nonsurvivors ( P 2-6: <= .02). Area under receiver operating characteristic curves (95% CI) for SI at 0 hour was 0.72 (0.5-0.9), 0.66 (0.5-0.8), and 0.77 (0.6-0.9) and at 6 hours was 0.8 (0.6-1), 0.75 (0.6-0.9), and 0.8 (0.7-1) in 3 groups. The cut-off values of SI 0 (sensitivity; specificity; PPV; NPV) in 3 groups: 1.98 (77; 75; 67; 83), 1.50 (65; 65; 68; 63), and 1.25 (90; 67; 77; 83) and SI6: 1.66 (85; 80; 73; 89), 1.36 (73; 70; 73; 70), and 1.30 (74; 73; 78; 69). Improvement of SI over 6 hours was associated with better outcome. Children with higher SI at both time points had higher mortality than those with SI score below the cut-offs ( P = .001). CONCLUSIONS: Age-specific SI cut-off values may identify children at high risk of early mortality in severe sepsis/septic shock and allow for better targeted management. PMID- 30278816 TI - A Novel Diabetic Mouse Model for Real-Time Monitoring of Clock Gene Oscillation and Blood Pressure Circadian Rhythm. AB - Diabetic patients have an increased prevalence of blood pressure (BP) circadian rhythm disruption, which is associated with an increased risk of target organ damage and detrimental cardiovascular events. Limited information is available regarding the role of clock genes in the disruption of BP circadian rhythm in diabetes due to the lack of a diabetic animal model that allows real-time monitoring of clock gene oscillation. Here, we generated a novel diabetic db/db mPer2Luc mouse model by crossing type 2 diabetic db/db mice with mPer2Luc knock in mice. The daily rhythms of BP, heart rate, locomotor activity, and food and water intake were acquired by radiotelemetry or using metabolic chambers. The daily oscillation of mPer2 bioluminescence was recorded by LumiCycle in real-time in tissue explants and using the IVIS system in vivo. Our results show that db/db mPer2Luc mice are obese, diabetic, and glucose intolerant. The db/db-mPer2Luc mice displayed a compromised BP daily rhythm, which was associated with disrupted daily rhythms in baroreflex sensitivity, locomotor activity, and metabolism, but not heart rate or food and water intake. The phase of the mPer2 daily oscillation was advanced to different extents in the explanted peripheral tissues from db/db mPer2Luc mice relative to control mice. In contrast, no phase shift was detected in mPer2 daily oscillations in the explanted SCN. Moreover, advanced phase shift of the mPer2 daily oscillation was detected in the liver, kidney and submandibular gland in vivo of db/db-mPer2Luc mice. In conclusion, the diabetic db/db-mPer2Luc mouse is a novel animal model that allows real-time monitoring of mPer2 circadian rhythms ex vivo and in vivo. The results from db/db-mPer2Luc mice suggest that the desynchrony of mPer2 daily oscillation in peripheral tissues contributes to the loss of BP daily oscillation in diabetes. PMID- 30278815 TI - Self-Reported Hearing Loss and Pure Tone Audiometry for Screening in Primary Health Care Clinics. AB - OBJECTIVE: To evaluate the performance of self-reported hearing loss alone and in combination with pure tone audiometry screening in primary health care clinics in South Africa. DESIGN: Nonprobability purposive sampling was used at 2 primary health care clinics. A total of 1084 participants (mean age 41.2 years; SD 15.5 years; range 16-97 years, 74.0% female) were screened using self-report and audiometry screening. Those failing audiometric screening and a sample of those who passed audiometric screening were also assessed by diagnostic pure time audiometry, to confirm or negate the finding of a hearing loss. RESULTS: Four hundred and thirty-six participants (40.2%) self-reported a hearing loss with no significant association with gender or race. One hundred and thirty-six participant (12.5%) self-reported hearing loss and failed audiometry screening (35 dB HL at 1, 2, and 4 kHz). Combining self-report with a second stage audiometry screening revealed a high test accuracy (81.0%) for hearing loss, being most accurate (86.1%) to identify high-frequency hearing loss. CONCLUSION: While self-report of hearing loss is an easy and time-efficient screening method to use at primary health care clinics, its accuracy may be limited when used in isolation and it may not be sufficiently sensitive to detect hearing loss. Combining a simple audiometry screening as a second-stage screen can significantly improve overall performance and efficiency of the screening protocol. PMID- 30278817 TI - Characteristics of Mail-Order Pharmacy Users: Results From the Medical Expenditures Panel Survey. AB - BACKGROUND: There is a paucity of research on the population characteristics of mail-order pharmacy users. OBJECTIVE: This study utilized a nationally representative sample to examine the characteristics of mail-order pharmacy users. METHODS: This study used data from the 2012 Medical Expenditure Panel Survey (MEPS). The outcome variable was defined as whether the participant had used a mail-order pharmacy during the study year. Logistic regression was conducted to determine the factors which influence mail-order pharmacy use. All analyses incorporated MEPS sampling weights to adjust for the complex survey design. RESULTS: Among the 14,106 adults included, approximately 18% of them had used a mail-order pharmacy at least once to fill their prescription in 2012. Compared to community pharmacy users, mail-order pharmacy users were more likely to be white, older, married, have a higher family income, a higher educational level, have health insurance, and have a prescription with at least a 30-day supply. There is no difference in gender or urban/rural disparity. In addition, mail-order pharmacy users had a lower percentage of out-of-pocket costs. CONCLUSION: Mail-order pharmacy use was significantly associated with certain patient characteristics. Policymakers should consider these characteristics when promoting mail-order pharmacy use. PMID- 30278818 TI - Does the plasma refilling coefficient change during hemodialysis sessions? AB - The filtration coefficient in the Starling equation is an important determinant of plasma refilling during hemodialysis. A method for calculating from clinical data an estimate of the filtration coefficient, called the refilling coefficient, was proposed in the past. The assumption behind this method was that the only drive for refilling is the increase in plasma oncotic pressure, and the remaining Starling forces have negligible effect. The refilling coefficient was observed to decrease during hemodialysis, and this was interpreted as a change in the filtration coefficient. The purpose of our study was providing an alternative explanation for the behavior of the refilling coefficient and, using clinical data and mathematical modeling, to predict the values of the immeasurable Starling forces and provide the theoretical basis for the interpretation of the refilling coefficient as the filtration coefficient. Blood volume and bioimpedance data from 23 patients undergoing hemodialysis were used to calculate the refilling coefficient according to the original formulation and to fit a two compartment model of protein and fluid transport. The changes in the other Starling forces were non-negligible, ranging from 19% to 60% of plasma oncotic pressure. The results showed that the decrease observed in the refilling coefficient is likely caused by neglecting important changes in the Starling forces while deriving the equation for the refilling coefficient. When these Starling forces were taken into account, constant filtration coefficient and dynamic refilling coefficient provided an equivalent description of the data in most cases. However, this was not true for a subgroup of sessions, which suggests that additional factors may also be responsible for the observed decrease in the refilling coefficient. PMID- 30278819 TI - Outcomes of an accelerated nonsurgical management protocol for hip fractures in the elderly. AB - The majority of hip fractures in elderly patients are managed surgically with superior outcomes. However, for patients who refuse surgery or are deemed medically unfit, traction used to be the mainstay of nonsurgical treatment, which is associated with prolonged hospitalization and inpatient complications from immobility. This study, therefore, aims to evaluate the outcomes of an early wheelchair mobilization protocol as an alternative nonsurgical treatment option. This is a retrospective study of 87 elderly patients who were managed nonsurgically for their hip fractures over a 1-year period. The accelerated rehabilitation protocol did not have them on traction but were instead mobilized with assistance as soon as possible after admission. Variables collected electronically include patient demographics, fracture characteristics, inpatient mobilization milestones, inpatient complications, Modified Functional Ambulation Classification (MFAC), Modified Barthel Index (MBI) scores, and radiological findings. Patients who were younger, could sit up earlier and had a shorter length of stay, were able to ambulate better at 6 months ( p value < 0.05). Patients with femoral neck fractures and shorter length of stay had better MFAC scores. A total of 58% of patients with radiological follow-up had displacement of their fractures with age, type of fracture, and length of stay as predictors ( p value < 0.05) The Charlson's score, day to sitting up, and day to transfer affect fracture healing ( p value < 0.05). The mean length of stay was 17 days and the 1-year mortality was 18%. Surgical therapy remains the preferred choice of management for patients with hip fractures. Early wheelchair mobilization leads to a shorter length of stay compared to traditional traction methods and comparable 1-year mortality rates with operative management. Despite this, complication rates remain high and only 48% of patients achieved ambulation by 1 year, with healing in only 24% of fractures. PMID- 30278820 TI - Association between MPO-463G > A polymorphism and chronic kidney disease: a meta analysis. AB - BACKGROUND/OBJECTIVE: Previous studies have shown that MPO -463G > A (rs2333227) might be associated with chronic kidney disease (CKD) susceptibility, but sample sizes of those studies are relatively small. Hence, we decided to perform a meta analysis to evaluate the association. Methods/main results: Two investigators search databases systematically and independently. Odds ratios and 95% confidence intervals were used to pool the effect size. Four articles with 618 cases and 932 controls in total were included in our meta-analysis. CONCLUSIONS: MPO -463G > A was not associated with CKD susceptibility in recessive model and homozygote comparison. MPO -463G > A was associated with increased risk of CKD in allelic comparison, heterozygote comparison and dominant model, however, the results lacked stability. Owing to insufficient data, the association between MPO -463G > A and CKD cannot be fully confirmed. PMID- 30278821 TI - Bearing Witness: Exploring the End-of-Life Needs of Homeless Persons and Barriers to Appropriate Care. AB - Traditional models of palliative care are largely inaccessible to homeless persons, and their preferences regarding end-of-life care are poorly understood. The purpose of the present scoping review is to summarize the burgeoning gray and academic literature on end-of-life care for homeless persons. Five medical databases, seven social science databases, and four gray literature databases were searched, resulting in 57 relevant titles. Six themes emerged: (a) Characteristics of homeless persons who require end-of-life care; (b) preferences and concerns of homeless persons approaching the end of life; (c) the role of spirituality for homeless persons at the end of life; (d) barriers to care at the patient, provider, and institutional or structural levels; (e) inclusive models of palliative care; and (f) implications for policy and practice. Practitioners and homeless persons must negotiate many obstacles in the provision and receipt of palliative care. However, there is tremendous potential and opportunity to improve the quality of life at the end of life for this vulnerable population. PMID- 30278822 TI - The effectiveness of cervical transforaminal epidural steroid injection for the treatment of neck pain due to cervical disc herniation: long-term results. AB - AIM: To investigate the long-term effect of fluoroscopy guided cervical transforaminal epidural steroid injection on neck pain radiating to the arm due to cervical disc herniation. MATERIALS & METHODS: 64 patients (26 women [40.6%], 38 men [59.4%]; mean age, 44.9 +/- 12.1 years) who had received fluoroscopy guided cervical transforaminal epidural steroid injection for neck pain due to cervical disc herniation at least 1 year before were included in the study. The effectiveness of transforaminal epidural steroid injection was assessed using data obtained by medical records and a standardized telephone questionnaire. Multiple linear regression analysis was applied to evaluate the factors affecting the pain reduction after injection and the duration of treatment effect. RESULTS: The mean duration of neck pain symptom was 23.3 +/- 23.9 months. Most of the patients received a single injection (50 patients, 78.1%). The mean time since injection at the time of interview was 21.4 +/- 9.4 months. There was a significant reduction in mean pain visual analog scale (VAS [10 cm]) score, from 8.6 +/- 1.4 at baseline to 3.2 +/- 2.5 at check visit two weeks after injection (p < 0.001). 52 patients (81.2%) reported pain relief of more than 50%. The mean duration of treatment effect was 13.3 +/- 9.44 months. Greater pain on the VAS was found to predict strongly the higher pain reduction and longer treatment effect (p = 0.042 and 0.011, respectively). CONCLUSION: The results suggested that cervical transforaminal epidural steroid injections might be an effective treatment for neck back pain radiating to the arm due to cervical disc herniation. PMID- 30278823 TI - Effects of adolescent exposure to behaviour change interventions on their HIV risk reduction in Northern Malawi: a situation analysis. AB - Understanding adolescents' translation of HIV and AIDS-related behaviour change interventions (BCI) knowledge and skills into expected behavioural outcomes helps us appreciate behaviour change dynamics among young people and informs evidence based programming. We explored the effects of adolescents' exposure to BCI on their HIV risk reduction in selected schools in Nkhatabay and Mzimba districts and Mzuzu city in Northern Malawi. The study used questionnaires as instruments. Data were collected between January and April 2017. Adolescent boys and girls [n = 552], ages 11-19 were randomly sampled to participate. Data analysis was through multiple regression and content analysis. Respondents included 324 female [58.7%] and 228 male [41.3%]. Multiple regression analysis indicated that exposure to BCI did not affect risk reduction in the study area. The best stepwise model isolated sexual experience ([Beta = .727, p = .0001, p < .05]) as having the strongest correlation with the dependent variable - risk reduction. BCI exposure was stepwise excluded ([Beta = -.082, p = .053, p > .05]). There was therefore no evidence against the null hypothesis of no relationship between adolescent exposure to BCI and their HIV risk reduction. Overall there was limited BCI knowledge and skills translation to behavioural risk reduction. The study points to the need to evaluate and redesign adolescent BCI in line with current behavioural dynamics among young people in Malawi. The findings have been used to inform the design and programming of a model to be tested for feasibility through a quasi-experiment in the second phase of our project. PMID- 30278825 TI - Evaluations versus stereotypes in emotion recognition: a replication and extension of Craig and Lipp's (2018) study on facial age cues. AB - Recently, Cognition and Emotion published an article demonstrating that age cues affect the speed and accuracy of emotion recognition. The authors claimed that the observed effect of target age on emotion recognition is better explained by evaluative than stereotype associations. Although we agree with their conclusion, we believe that with the research method the authors employed, it was impossible to detect a stereotype effect to begin with. In the current research, we successfully replicate previous findings (Study 1). Furthermore, by changing the comparative context, Study 2 provides a first test of age-stereotypes affecting emotions recognition. We discuss recommendations for future studies in the domain of social categorisation and emotion recognition. PMID- 30278824 TI - Effect of apigenin on apoptosis induced by renal ischemia/reperfusion injury in vivo and in vitro. AB - OBJECTIVES: This study aims to investigate the effects and molecular mechanisms of apigenin (ApI) on renal ischemia/reperfusion (I/R) injury in vivo and in vitro. METHODS: In vivo, the left renal artery was clamped for 45 min and the right kidney was removed to study renal I/R injury on Sprague-Dawley (SD) rats. ApI was injected at 60 min before renal ischemia. In vitro, renal tubular epithelial cells (HK-2) were pretreated with or without ApI (20 uM) for 60 min and then treated with hypoxia/reoxygenation (H/R). Renal function, histology, cells apoptosis, and cell viability were tested. Furthermore, the potential molecular mechanisms were assessed. RESULTS: ApI pretreatment could significantly alleviated the renal function and the pathological damage as well as cells apoptosis after I/R injury. Meanwhile, ApI treatment protects H/R induced HK-2 cell apoptosis in vitro. The results of Western blot showed that ApI significantly increased the expressions of B-cell lymphoma 2 (Bcl-2) and phosphor AKt (p-AKt), Phosphoinositide 3-kinase (PI3K), while down-regulated the expressions of Caspase3 and Bax induced by H/R injury. CONCLUSIONS: ApI pretreatment can protect renal function against I/R injury and prevent renal tubular cells from apoptosis in vivo and in vitro which might through PI3K/Akt mediated mitochondria-dependent apoptosis signaling pathway. PMID- 30278826 TI - Decision Science: A New Hope. AB - Decision science is an area of enquiry that crosses many disciplines, from psychology to economics, each with their own perspective of decision-making. Traditionally, mathematicians have envisaged decision-making as a purely rational endeavor, whereas psychologists and behavioral economists have critiqued this narrative and suggested that cognitive short cuts are the real mechanisms behind how decisions are made. However, contemporary dual process theorists argue that two systems of the mind exist: system 1 (intuitive decision-making) and system 2 (rational decision-making). The current review will present a relatively new metaphor for decision-making: the unified threshold model. This model is a global approach to decision-making which allows both intuitive and rational decision making processes to be explained in a more flexible manner than the dual process model. This review will introduce the reader to different types of threshold models (counter and diffusion), their assumptions, and their ability to explain decision-making behavior. Implications and future research will also be discussed. In summary, the aim of this review is to highlight that a rather than the unified threshold model of decision-making may give a more adequate explanation of decision-making data in comparison to previous models and theories. PMID- 30278827 TI - The BETACONNECTTM system: MS therapy goes digital. AB - Adherence to long-term treatment in chronic diseases such as multiple sclerosis is challenging. Many disease-modifying drugs (DMDs) for MS need to be injected. Injection devices may improve satisfaction with the injection procedure and boost adherence. Meeting patients' needs in handling and design of autoinjectors and other supporting elements may be key to successful therapy. The BETACONNECTTM system is a platform-based approach in DMD therapy. It combines autoinjector technology with digital tools to support patient self-management and facilitate communication between patients and healthcare providers. Here, we describe the components of the BETACONNECT system and review data on patients' satisfaction with the BETACONNECT autoinjector and how it compares to other devices. Additionally, we present first data on patients' satisfaction with the myBETAappTM. PMID- 30278828 TI - Social-emotional functioning in planned lesbian families: does biological versus non-biological mother status matter? An Italian pilot study. AB - To date, few studies have investigated the social-emotional functioning of planned lesbian families, wherein only one parent is the biological mother of the child. We examined if being a biological versus non-biological mother plays a role in planned lesbian couple functioning and mother-infant play interactions. The present study analyzes the attachment state of mind, couple alliance, parenting stress, and emotional availability in a sample of 40 mothers (20 biological and 20 non-biological). The results showed that mothers' life-long attachment experiences and related mental states of mind, rather than biological relatedness between the parent and child, matter in a mother and child's emotional involvement in parent-child interaction. Furthermore, the results confirmed the different impact of the perceived quality of the couple alliance on biological and non-biological mothers. The findings obtained elucidated what counts in this new family typology, and constitute a heuristic solicitation for future studies to better understand the key factors and mechanisms implied in social-emotional functioning. PMID- 30278829 TI - Misoprostol-Induced Modification of the Notch Signaling Pathway in the Human Cervix. AB - The complex and multifactorial mechanisms that initiate and sustain the early labor process in the human uterus and cervix are still not well defined. Cervical maturation or ripening is likely to play a key role in preparing for birth. Prostaglandins have many different functions, including the regulation of uterine contractility and structure during pregnancy. The prostaglandin E1 analogue misoprostol is frequently used as a uterotonic and cervical ripening agent. Notch is a transmembrane receptor family responsible for basic functions such as cell survival, cell-cell communication, and differentiation and decidualization in pregnancy. However, our understanding of the effect of Notch signaling on the cervical ripening process is limited. This study was conducted in 20 pregnant women aged at 12 to 20 weeks of gestation undergoing medical abortion for fetal or maternal indications. True-Cut needle biopsies were taken from the anterior cervix 4 hours after oral ingestion of 200-MUg misoprostol or before the ingestion of misoprostol in the control group. Cervical expression of Notch receptors and ligands changed during the early phase of prostaglandin-induced preterm labor. Four hours after the administration of misoprostol, it was seen that N1 expression increased in muscle, while DLL1 and J2 expression increased in blood vessels, and N4 expression increased in macrophages. Knowing the mechanisms that initiate preterm birth is the most important step in planning the treatments and actions to prevent premature birth. As a signal that affects and perhaps directs preterm labor, Notch is prone to be an important actor in this process. PMID- 30278831 TI - Antigenotoxic effect of melatonin against mercuric chloride in human peripheral blood lymphocytes. AB - Melatonin (MLT) is an extraordinary antioxidant, which plays an important role in reducing reactive oxygen species (ROS) by scavenging them directly or indirectly. Mercury (Hg) is a heavy metal, which induces cytogenetic alterations via various mechanisms, leading to genotoxicity. It induces genotoxicity by enhancing the ROS chiefly. In the present study, the antigenotoxic effect of MLT was evaluated against mercuric chloride (HgCl2). All experiments were conducted in vitro in peripheral blood lymphocytes. Blood cultures were exposed to various concentrations of HgCl2 (2.63, 6.57, and 10.52 microM) for 24 h to study a range of genotoxic parameters. MLT (0.2 mM) supplementation, alone and in combination with the high concentration of Hg, was administered to blood cultures for 24 h. Genotoxic parameters, such as chromosomal aberrations (CAs; structural aberrations (chromatid gaps and breaks, chromosomal gaps and breaks) and numerical aberrations), micronuclei (MNs), and comet assay, were evaluated and analyzed using suitable statistical analysis. Hg treatment revealed a significant increase in CAs, MNs, and comet length. Co-supplementation of MLT along with Hg showed marked protection of these genotoxic end points in treated cultures. In conclusion, our findings suggest that MLT protects against Hg-induced augmentation in genotoxic indices because of its antioxidant property. PMID- 30278830 TI - An Automated Preprocessing Method for Diffuse Optical Tomography to Improve Breast Cancer Diagnosis. AB - The ultrasound-guided diffuse optical tomography is a noninvasive imaging technique for breast cancer diagnosis and treatment monitoring. The technique uses a handheld probe capable of providing measurements of multiple wavelengths in a few seconds. These measurements are used to estimate optical absorptions of lesions and calculate the total hemoglobin concentration. Any measurement errors caused by low signal to noise ratio data and/or movements during data acquisition would reduce the accuracy of reconstructed total hemoglobin concentration. In this article, we introduce an automated preprocessing method that combines data collected from multiple sets of lesion measurements of 4 optical wavelengths to detect and correct outliers in the perturbation. Two new measures of correlation between each pair of wavelength measurements and a wavelength consistency index of all reconstructed absorption maps are introduced. For phantom and patients' data without evidence of measurement errors, the correlation coefficient between each pair of wavelength measurements was above 0.6. However, for patients with measurement errors, the correlation coefficient was much lower. After applying the correction method to 18 patients' data with measurement errors, the correlation has improved and the wavelength consistency index is in the same range as the cases without wavelength-dependent measurement errors. The results show an improvement in classification of malignant and benign lesions. PMID- 30278832 TI - 41-Week Study of Progressive Diabetic Nephropathy in the ZSF1 fa/faCP Rat Model. AB - This symposium synopsis summarizes key results from a 41-week study of diabetic nephropathy (DN) in the type 2 diabetic ZSF1 fa/faCP rat model. During this study, we conducted longitudinal analysis of biomarkers, renal histopathology, ultrastructural assessment, renal quantitative image analysis, and transcriptome analysis of glomerular-enriched tissue. We concluded that there is translational value for using the ZSF1 rat model in mechanistic and therapeutic intervention efficacy studies for type 2 DN. PMID- 30278833 TI - Skeletal Anomalies in Senegalese Sole ( Solea senegalensis), an Anosteocytic Boned Flatfish Species. AB - Skeletal anomalies affect animal welfare and cause important economic problems in aquaculture. Despite the high frequency of skeletal problems in reared Solea senegalensis, there is lack of information regarding the histological features of normal and deformed vertebrae in this flatfish. The aim of this study was to describe the histopathological and radiographical appearance of vertebral body anomalies. Sixty-seven juvenile fish were radiographically examined 104 or 105 days after hatching. Through radiographic images, vertebral segments were selected and processed for histopathological examination from 7 normal and 7 affected fish. Alterations in bone shape and vertebral fusion were the most significant anomalies in the vertebral bodies. These alterations occurred most frequently between the last 3 abdominal vertebrae and the first 10 caudal centra. Radiographically, deformed vertebrae showed flattening of the endplates and narrowing of the intervertebral spaces. The radiographic findings concurred with the histological lesions where affected vertebrae exhibited irregular endplates and changes in trabecular bone. Radiolucent cartilaginous tissue was evident in the endplates of the deformed vertebra and, in some cases, the cartilaginous material extended from the growth zone into the intervertebral space. These changes were likely the primary alterations that led to vertebral fusion. Fused vertebrae were often reshaped and showed a reorganization of the trabeculae. The formation of metaplastic cartilage is frequent in a variety of anomalies affecting teleost species. PMID- 30278834 TI - Scheduled Emergency Trauma Operation: The Green Line Orthopedic Trauma Surgery Process Of Care. AB - BACKGROUND AND AIMS: Traditionally, patients requiring an orthopedic emergency operation were admitted to an inpatient ward to await surgery. This often led to congestion of wards and operation rooms while, for less urgent traumas, the time spent waiting for the operation often became unacceptably long. The purpose of this study was to evaluate the flow of patients coded green in a traffic light based coding process aimed at decreasing the burden on wards and enabling a scheduled emergency operation in Central Finland Hospital. MATERIALS AND METHODS: Operation urgency was divided into three categories: green (>48 h), yellow (8-48 h), and red (<8 h). Patients, who had sustained an orthopedic trauma requiring surgery, but not inpatient care (green), were assigned an operation via green line process. They were discharged until the operation, which was scheduled to take place during office hours. RESULTS: Between January 2010 and April 2015, 1830 green line process operations and 5838 inpatient emergency operations were performed. The most common green line process diagnoses were distal radial fracture (15.4% of green line process), (postoperative) complications (7.7%), and finger fractures (4.9%). The most common inpatient emergency operation diagnosis was hip fracture (24.3%). Green line process and inpatient emergency operation patients differed in age, physical status, diagnoses, and surgical procedures. CONCLUSION: The system was found to be a safe and effective method of implementing orthopedic trauma care. It has the potential to release operation room time for more urgent surgery, shorten the time spent in hospital, and reduce the need to operate outside normal office hours. PMID- 30278835 TI - Advances and Challenges on New Therapies and Clinical Targets of Acute Kidney Injury. AB - Acute kidney injury (AKI) is encountered in high-risk hospital settings where patients often suffer systemic illnesses, undergo surgery, or receive medications toxic to the kidneys. It is associated with high morbidity and mortality. Despite advances in understanding the pathophysiologic mechanisms involved in AKI, our ability to detect AKI early is limited, and outcomes remain unchanged. Once AKI is identified by the traditional markers of urine output and serum creatinine, the main therapeutic intervention is usually supportive care and/or renal replacement therapy until renal injury resolves. Urine biomarkers provide an optimistic future, offering the ability to identify patients at high risk for AKI such that preventative measures can be introduced. In this article, the etiologies of AKI are discussed, new biomarkers are assessed, and areas for further investigation are suggested. PMID- 30278836 TI - Immunohistochemical Profiling of Canine Intestinal T-Cell Lymphomas. AB - Human enteropathy-associated T-cell lymphoma (EATL) is classified into 2 distinct subgroups based on their phenotypes (type I and type II). Canine intestinal T cell lymphoma can be morphologically classified into large and small cell lymphomas (LCL and SCL, respectively). Their association with human EATL or immunohistochemical and biological features has not been well characterized. In this study, the immunohistochemical profiles of 17 cases of LCL and 33 cases of SCL were evaluated with markers used for human EATL classification. Morphologically, LCL was characterized by sheet-like proliferation of large to moderately sized neoplastic lymphocytes, with scant clear cytoplasm and pleomorphic, irregularly shaped nuclei containing distinctive nucleoli and scattered chromatin. In contrast, SCL was characterized by the proliferation of monomorphic small neoplastic lymphocytes, accompanied by infiltration of nonneoplastic plasma cells. Interestingly, 8 cases demonstrated mixed LCL and SCL morphologies. Granular cytoplasmic expression of granzyme B was observed in most LCL and SCL cases. Membranous expression of CD56 was demonstrated in only 2 of 17 LCL and 0 of 33 SCL cases. Coexpression of CD20 by neoplastic T cells was observed in more SCL cases (16/33; 48%) than LCL cases (1/17; 6%). The CD56 positive cells in 2 cases were negative for CD20. Although canine LCL shares common features with human EATL type I, canine SCL cells and human EATL type II differ in their immunophenotype. Canine intestinal T-cell lymphoma had a homogeneous immunophenotype regardless of cell morphology. The findings of this study may indicate large cell transformation of SCL rather than 2 distinct entities. PMID- 30278837 TI - Glomerulonephritis in Animal Models and Human Medicine: Discovery, Pathogenesis, and Diagnostics. AB - Glomerulonephritis (GN) is inflammation of glomeruli. The four major categories that cause human GN are mediated by immunoglobulin or complement or both, and they include (1) immune complex-mediated GN, (2) anti-glomerular basement membrane-mediated GN, (3) antineutrophil cytoplasmic autoantibody-mediated GN, and (4) complement factor 3 glomerulopathy mediated by complement dysregulation. Initiating processes include infection, autoimmunity, exogenous antigens, and neoplasia. Often there are predisposing and modulating genetic, epigenetic, and/or environmental factors. Animal models facilitated the recognition and elucidation of the pathogeneses of all four categories of GN, and they continue to be used in preclinical studies to identify and validate therapies for all four types of GN. Advanced diagnostic modalities (e.g., transmission electron microscopy and immunofluorescence) are helpful and sometimes required for the correct categorization of GN in humans and animals. This review provides historical background on the discovery of the different GN pathogeneses, describes some of the animal models used to discover and understand each GN pathogenic category, reviews the diagnostic classification of each category of GN, and compares human GN to spontaneous forms of nonhuman GN. PMID- 30278838 TI - Classification, Scoring, and Quantification of Cell Death in Tissue Sections. AB - The analysis and description of the appearance of cell death in tissue sections can add valuable information to research studies. The scoring/grading and quantification of cell death can be used either as part of a larger scoring scheme or as the final end point of a study. The degree of precision needed is study dependent and will be determined by the question being addressed and the complexity of the model. The methods one uses to quantify cell death are often guided by the tissue of interest. For example, in the brain, it is sometimes necessary to examine death of specific neuronal populations, whereas in more homogeneous tissue such as a tumor xenograft, quantification can be done on a whole-slide basis. In addition to examination of hematoxylin and eosin (HE) stained sections, immunohistochemistry can be employed to highlight areas of cell death or to identify specific types of cell death, for example, when differentiating apoptosis from necrosis. Automated quantification can be useful in generating statistically comparable data from HE-stained or immunolabeled samples. The rapidly expanding classification of cell death requires the use of multiple techniques to identify them in vivo. This article will provide examples of how different methods of examining and quantifying cell death are used in a variety of research areas, ranging from semiquantitative evaluation in HE-stained intestine to automated quantification of immunohistochemistry-immunolabeled brain and tumor xenografts. The recently described process of necroptosis will be discussed briefly, with the description and example of the methods used to differentiate this from apoptosis. PMID- 30278839 TI - Acute pesticide poisoning and related factors among farmers in rural Western Iran. AB - Although acute pesticide poisoning (APP) is known to be a major health concern among farmers in developing countries, knowledge of its prevalence and risk factors is limited. The purpose of this study was to investigate the prevalence and a broad range of potential work-related risk factors of APP among Iranian farmers and farm workers. This cross-sectional study was conducted in rural areas of the Twiserkan County in Iran. In this study, there were 474 farmers and farm workers who had used pesticide 1 week before data collection. Participants were selected from 104 villages. Data were gathered using a questionnaire and analyzed using STATA (version 14.2 SE). Binary logistic regression and multinomial logistic regression were employed. The results of this study showed that 286 (60.3%) farmers and farm workers who applied pesticides suffered from work related APP. Most frequent APP symptoms were runny nose (29.8%) and headache (25.1%). Five risk factors were identified, including annual income ( p < 0.05), number of farming years (odds ratio (OR) = 0.31), number of spraying years (OR = 2.40), place of pesticide storage (OR = 2.69), and type of sprayer ( p < 0.05). The results of this study indicated that APP is prevalent among the studied farmers. Some work-related factors play an important role in APP among Iranian rural farmers. In addition, the magnitude of these risk factors differed significantly by severity of acute and somatic pesticide poisoning. PMID- 30278840 TI - [Lipedema, the Unknown]. AB - Lipedema, the Unknown Abstract. Lipoedema patients suffer from the widespread ignorance of their pathology. Considering its chronic, progressive and invalidating character, the early diagnosis of the disease must constitute the challenge of their caregivers in order to limit medical wanderings and the occurrence of complex clinical pictures. Treatments allow the reduction of lipedema and its long-term control. Management must be individualized according to the stage of the disease. The adherence of the patient, the supervision and the support of the practitioner are essential for obtaining the best results. PMID- 30278841 TI - ? PMID- 30278842 TI - ?

Advance Care Planning (ACP) is a standardized consultation process in which patients define their therapy goals for future medical treatments with the help of a qualified health care facilitator. This way, ACP increases the probability that patients' wishes are fulfilled in case of decisional incapacity. The aim of this study was to implement a previously tested Swiss ACP program in two Swiss nursing homes to better understand the resulting processes, chances and difficulties. For this purpose focus group interviews were conducted after first implementation steps. The results show that an ACP implementation needs and must be coordinated with an approach covering the entire health system.

PMID- 30278846 TI - [Surgical Treatment for Lipedema]. AB - Surgical Treatment for Lipedema Abstract. Lipedema is a progressive disease that occurs in adolescence and affects one in nine women. The signs are limited to the lower limbs. Early signs are nonspecific, which is why the diagnosis is often ignored. Later, pain and heaviness of lower limbs become predominant. Finally, at an advanced stage, tissue fibrosis is associated with significant edema. At this stage, patients become severely disabled and bedridden. At the early stage, the treatment is conservative. Liposuction is indicated at the onset of pain. Its effectiveness pain and long-term control has been demonstrated on. Finally, late stages require heavy and complex surgeries combining dermolipectomy and liposuction. PMID- 30278847 TI - [CME: Ethylene Glycol Intoxication]. AB - CME: Ethylene Glycol Intoxication Abstract. Ethylene glycol is a sweet-tasting alcohol used in common antifreeze and other industrial solutions. Without appropriate therapy, intoxication with ethylene glycol can result in severe metabolic acidosis, acute renal failure, and in death. After gastrointestinal resorption, hepatic metabolism starts with oxidation by alcohol dehydrogenase and results in severe anion gap metabolic acidosis. Other metabolic products are calcium oxalate crystals, which can deposit in several tissues like the kidneys and lead to acute tubular necrosis with reversible renal failure. The crucial therapeutic step is rapid inhibition of alcohol dehydrogenase with fomepizole or ethanol to avoid the formation of toxic metabolites. Additionally, haemodialysis is the most effective way to eliminate ethylene glycol as well as its toxic metabolites. If therapy is initiated rapidly, prognosis is favorable. PMID- 30278848 TI - [Lipedema: Which Etiological Pathways?] AB - Lipedema: Which Etiological Pathways? Abstract. The pathogenesis and epidemiology of lipedema are uncertain, and its diagnosis often delayed. Lipedema almost exclusively affects women, and a link to sex hormones is likely. The metabolic risk of this accumulation of fat in the lower limbs is not known, and weight loss has no impact on the morphology of the lower limbs. Due to the aesthetic discomfort and frequent initial misdiagnosis which results in inappropriate treatment, this condition can lead to significant psychological suffering for the patient. A better understanding of this disease is essential to the proper diagnosis and support for these patients, as well as guiding them in the effective care. PMID- 30278849 TI - ?

PMID- 30278852 TI - Chronic Neurological Disease Due to Methylmercury Poisoning. AB - Organic mercury, especially methylmercury, poisoning causes chronic neurological disease predominantly affecting the brain. There have been documented exposures from eating fish from contaminated waters in Japan and in northwestern Ontario and in Iraq from eating bread made from seed wheat treated with methylmercuric fungicide. The neurological disease is called Minamata disease in Japan. Visual field constriction due to involvement of the calcarine cortex, sensory disturbance due to involvement of the somatosensory cortex, and cerebellar ataxia due to involvement of granule cell neurons of the cerebellum are common and characteristic features due to methylmercury poisoning. Other neurological features include dysarthria, postural and action tremor, cognitive impairment, and hearing loss and dysequilibrium. In contrast, peripheral nerve disease is more characteristic of inorganic mercury intoxication. Similarly, psychosis is more typical of exposure to inorganic mercury, which has been documented in the felt hat industry ("mad hatter"). Laboratory tests (e.g., on blood and hair and toenail samples) are of limited value in the assessment of chronic neurological disease due to mercury poisoning because they may not reflect remote neuronal injury due to mercury. Methylmercury also causes injury to fetal brains during development. There is no effective treatment. PMID- 30278853 TI - A randomized controlled trial of working memory and processing speed training in schizophrenia. AB - BACKGROUND: Although prior research has shown that cognitive training may improve cognition for schizophrenia patients, it is currently unclear which domains of cognition should be targeted in training. One suggestion is to target low- or mid level cognitive processes. In particular, working memory (WM) and processing speed (PS) have been named as two key areas of impairment in schizophrenia, and two domains of cognition that are linked to higher-order cognition and daily functioning. This study aimed to investigate the near-transfer (transfer of gains to related contexts), far-transfer (transfer of gains to unrelated contexts), and real-world gains associated with WM and PS training in schizophrenia. METHODS: Eighty-three participants with schizophrenia were recruited and randomly assigned to computerized WM training, PS training, or a no-training control group. Outcome measures included WM, PS, fluid intelligence, executive functioning, social cognition, and daily functioning and symptoms. RESULTS: PS training led to significant gains in untrained PS tasks, as well as gains in far-transfer tasks that required speed of processing. WM training did not lead to gains in untrained WM tasks and showed inconsistent effects on some far-transfer tasks. CONCLUSIONS: These results suggest some benefit of domain-specific cognitive training, specifically PS training, in schizophrenia. Far-transfer of gains to other cognitive domains and to real-world functioning may not occur after targeted WM or PS training, though non-specific effects (e.g. through behavioral activation, increased motivation) may lead to improvements in some tasks. Future studies should continue to investigate the mechanisms by which cognitive training may enhance cognition and functioning in schizophrenia.

AB - OBJECTIVES: Although subjective cognitive complaints (SCC) are an integral component of the diagnostic criteria for mild cognitive impairment (MCI), previous findings indicate they may not accurately reflect cognitive ability. Within the Alzheimer's Disease Neuroimaging Initiative, we investigated longitudinal change in the discrepancy between self- and informant-reported SCC across empirically derived subtypes of MCI and normal control (NC) participants. METHODS: Data were obtained for 353 MCI participants and 122 "robust" NC participants. Participants were classified into three subtypes at baseline via cluster analysis: amnestic MCI, mixed MCI, and cluster-derived normal (CDN), a presumptive false-positive group who performed within normal limits on neuropsychological testing. SCC at baseline and two annual follow-up visits were assessed via the Everyday Cognition Questionnaire (ECog), and discrepancy scores between self- and informant-report were calculated. Analysis of change was conducted using analysis of covariance. RESULTS: The amnestic and mixed MCI subtypes demonstrated increasing ECog discrepancy scores over time. This was driven by an increase in informant-reported SCC, which corresponded to participants' objective cognitive decline, despite stable self-reported SCC. Increasing unawareness was associated with cerebrospinal fluid Alzheimer's disease biomarker positivity and progression to Alzheimer's disease. In contrast, CDN and NC groups over-reported cognitive difficulty and demonstrated normal cognition at all time points. CONCLUSIONS: MCI participants' discrepancy scores indicate progressive underappreciation of their evolving cognitive deficits. Consistent over-reporting in the CDN and NC groups despite normal objective cognition suggests that self-reported SCC do not predict impending cognitive decline. Results demonstrate that self-reported SCC become increasingly misleading as objective cognitive impairment becomes more pronounced. (JINS, 2018, 24, 842-853).

AB - General practitioners (GPs) play a key role in the return-to-work process, and yet their experiences working with workplace Return-to-Work Coordinators (RTWCs) have rarely been studied. The aim of this paper is to provide insights from the GP perspective about their experiences with workplace RTWCs and their preparedness for the role. GPs from Australian states and territories where legislation mandates workplaces employ a RTWC were requested to complete a questionnaire on their experiences with workplace RTWCs. Fifty GPs completed a questionnaire on the preparedness of RTWCs in relation to their role, with 58% (n=29) indicating RTWCs require more training. A total of 78% (n=39) of respondents considered RTWCs were important in assisting injured workers return to work, with 98% (n=49) ranking trustworthiness, respectfulness and ethicalness as the most important or an important trait for a RTWC to possess. Interestingly, 40% (n=20) of respondents themselves reported having no training in the return-to work process. GPs acknowledge the importance of the workplace RTWC in the return to-work process, and the results highlight the need for RTWCs to possess specific traits and undergo appropriate training for the facilitation of a successful return to work for injured workers. PMID- 30278860 TI - Identification of Carboxylesterase, Butyrylcholinesterase, Acetylcholinesterase, Paraoxonase, and Albumin Pseudoesterase in Guinea Pig Plasma through Nondenaturing Gel Electrophoresis. AB - Drugs to protect against nerve agent toxicity are tested in animals. The current preferred small animal model is guinea pigs because their plasma bioscavenging capacity resembles that of NHP. We stained nondenaturing polyacrylamide slab gels with a variety of substrates, inhibitors, and antibodies to identify the esterases in heparinized guinea pig plasma. An intense band of carboxylesterase activity migrated behind albumin. Minor carboxylesterase bands were revealed after background activity from paraoxonase was inhibited by using EDTA. The major butyrylcholinesterase band was a disulfide-linked dimer. Incubation with the antihuman butyrylcholinesterase antibody B2 18-5 shifted the butyrylcholinesterase dimer band to slower migrating complexes. Carboxylesterases were distinguished from butyrylcholinesterase by their sensitivity to inhibition by bis-p-nitrophenyl phosphate. Acetylcholinesterase tetramers formed a complex with the antihuman acetylcholinesterase antibody HR2. Organophosphorus toxicants including cresyl saligenin phosphate, dichlorvos, and chlorpyrifos oxon irreversibly inhibited the serine esterases but not paraoxonase. Albumin pseudoesterase activity was seen in gels stained with alpha- or beta-naphthyl acetate and fast blue RR. We conclude that guinea pig plasma has 2 types of carboxylesterase, butyrylcholinesterase dimers and 5 minor butyrylcholinesterase forms, a small amount of acetylcholinesterase tetramers, paraoxonase, and albumin pseudoesterase activity. A knockout mouse with no carboxylesterase activity in plasma is available and may prove to be a better model for studies of nerve agent toxicology than guinea pigs.

AB - This study examines catch-up immunisation for people of refugee-like background in Victoria, exploring effective models of service delivery to complete catch-up vaccinations. The analysis is based on: (i) review of the medical literature, Commonwealth and Victorian government immunisation policy and immunisation patient information; (ii) review of vaccination coverage and service delivery data; and (iii) stakeholder interviews completed in 2014 with 45 people from 34 agencies, including 9 local government areas in Victoria. Although refugees and asylum seekers all need catch-up vaccinations on arrival, they face significant barriers to completing immunisation in Australia. Analysis suggests missed opportunities by service providers and perceptions that catch-up vaccination is time-consuming, difficult and resource-intensive. Service delivery is fragmented across primary care and local government, and pathways depend on age, location and healthcare access. There are strengths, but also limitations in all current service delivery models. Gaps in vaccine funding for refugee-like populations have now been addressed through Commonwealth initiatives, however migration is still not well considered in immunisation policy, and existing systems for notification payments do not capture catch-up vaccination for these groups. Providers identify areas for improvement in professional development and support, patient information, patient-held records and immunisation surveillance data. PMID- 30278863 TI - Acknowledging Those Who Have Contributed Significantly to Our Profession: The Academy Honors. PMID- 30278864 TI - The Effect of Increased Cognitive Demand on Auditory Processing Assessment. AB - BACKGROUND: Auditory processing (AP) is commonly regarded as the perceptual processing of auditory information in the central nervous system. However, the degree to which higher level cognitive processes are involved in AP or its disorders is contentious. Furthermore, there is little evidence regarding the effects of nonauditory cognitive processes on the various tests of AP in common clinical usage and thus on clinical diagnoses of auditory processing disorder. PURPOSE: To determine the effects of increased cognitive demand, generated by using a dual-task paradigm, on performance on different AP tests and types of AP tests in common clinical usage. In addition, to investigate the relationship between executive function and changes in AP test performance associated with increased cognitive demand. RESEARCH DESIGN: Counterbalanced repeated measures design, with assessment of AP test performance both on its own and in a dual-task paradigm designed to increase cognitive demand. STUDY SAMPLE: Twenty-nine young adults, with no reported hearing, learning, language or attention difficulties, English as first language, and hearing and middle-ear status within normal limits. DATA COLLECTION AND ANALYSIS: Testing was completed within a single 90 min session. A selection of standard AP tests, representing both adaptive and nonadaptive tests, as well as tests employing difference scores, was administered. These were Competing Sentences Test, Dichotic Digits Test, Frequency Pattern Test (nonadaptive tests); and Listening in Spatialized Noise Sentences test, conditions "same-voice, 0 degrees ", "different-voice, 0 degrees ", and "same-voice, 90 degrees " (adaptive tests), from which the difference scores "talker advantage" and "spatial advantage" were also derived. Each AP test was completed on its own (alone condition), and simultaneously with a visually presented task (dual-task condition). Executive function was assessed using the phonemic subtest of the Verbal Fluency Test. Nonparametric statistical test procedures were used. RESULTS: All five AP measures obtained from the nonadaptive tests showed a significant performance decrement in the dual-task condition compared with the alone condition, with one exception because of a strong ceiling effect. By contrast, none of the three AP measures obtained from the adaptive tests showed a significant performance decrement in the dual-task condition. Furthermore, neither of the two AP measures based on difference scores showed a significant performance decrement, but this finding simply reflects the lack of significant decrements in the relevant raw scores. Consistent with past reports of associations between executive function and AP performance, a significant positive correlation was found between executive function scores and performance on the Dichotic Digits Test. However, there were no significant correlations between executive function scores and changes in AP test scores between alone and dual-task conditions. CONCLUSIONS: Performance on commonly used nonadaptive tests of AP was significantly compromised by the increased cognitive demand resulting from the dual-task paradigm. By contrast, performance on AP measures obtained by adaptive test procedures was not significantly affected. Further investigation of the resilience to increased cognitive demand of the adaptive tests used here, and other adaptive tests of AP, is warranted. Results from this study support the further development of computerized adaptive tests of AP for use in clinical test batteries.

AB - BACKGROUND: The Nucleus(r) 6 sound processor is now compatible with the Nucleus(r) 22 (CI22M)-Cochlear's first generation cochlear implant. The Nucleus 6 offers three new signal processing algorithms that purportedly facilitate improved hearing in background noise. PURPOSE: These studies were designed to evaluate listening performance and user satisfaction with the Nucleus 6 sound processor. RESEARCH DESIGN: The research design was a prospective, single participant, repeated measures design. STUDY SAMPLE: A group of 80 participants implanted with various Nucleus internal implant devices (CI22M, CI24M, Freedom(r) CI24RE, CI422, and CI512) were recruited from a total of six North American sites. DATA COLLECTION AND ANALYSIS: Participants had their external sound processor upgraded to the Nucleus 6 sound processor. Final speech perception testing in noise and subjective questionnaires were completed after four or 12 weeks of take-home use with the Nucleus 6. RESULTS: Speech perception testing in noise showed significant improvement and participants reported increased satisfaction with the Nucleus 6. CONCLUSION: These studies demonstrated the benefit of the new algorithms in the Nucleus 6 over previous generations of sound processors. PMID- 30278866 TI - Using Microphone Technology to Improve Speech Perception in Noise in Children with Cochlear Implants. AB - BACKGROUND: Cochlear implant (CI) users are affected more than their normal hearing (NH) peers by the negative consequences of background noise on speech understanding. Research has shown that adult CI users can improve their speech recognition in challenging listening environments by using dual-microphone beamformers, such as adaptive directional microphones (ADMs) and wireless remote microphones (RMs). The suitability of these microphone technologies for use in children with CIs is not well-understood nor widely accepted. PURPOSE: To assess the benefit of ADM or RM technology on speech perception in background noise in children and adolescents with cochlear implants (CIs) with no previous or current use of ADM or RM. RESEARCH DESIGN: Mixed, repeated measures design. STUDY SAMPLE: Twenty (20) children, ten (10) CI users (mean age 14.3 yrs) who used Advanced Bionics HiRes90K implants with research Naida processors, and ten (10) NH age matched controls participated in this prospective study. INTERVENTION: CI users listened with an ear-canal level microphone, T-Mic (TM), an ADM, and a wireless RM at different audio-mixing ratios. Speech understanding with five microphone settings (TM 100%, ADM, RM + TM 50/50, RM + TM 75/25, RM 100%) was evaluated in quiet and in noise. DATA COLLECTION AND ANALYSIS: Speech perception ability was measured using children's spondee words to obtain a speech recognition threshold for 80% accuracy (SRT80%) in 20-talker babble where the listener sat in a sound booth 1 m (3.28') from the target speech (front) and noise (behind) to test five microphone settings (TM 100%, ADM, RM + TM 50/50, RM + TM 75/25, RM 100%). Group performance-intensity functions were computed for each listening condition to show the effects of microphone configuration with respect to signal-to-noise ratio (SNR). A difference score (CI Group minus NH Group) was computed to show the effect of microphone technology at different SNRs relative to NH. Statistical analysis using a repeated-measures analysis of variance evaluated the effects of the microphone configurations on SRT80% and performance at SNRs. Between-groups analysis of variance was used to compare the CI group with the NH group. RESULTS: The speech recognition was significantly poorer for children with CI than children with NH in quiet and in noise when using the TM alone. Adding the ADM or RM provided a significant improvement in speech recognition for the CI group over use of the TM alone in noise (mean dB advantage ranged from 5.8 for ADM to 16 for RM100). When children with CI used the RM75 or RM100 in background babble, speech recognition was not statistically different from the group with NH. CONCLUSION: Speech recognition in noise performance improved with the use of ADM and RM100 or RM75 over TM-only for children with CIs. Alhough children with CI remain at a disadvantage as compared with NH children in quiet and more favorable SNRs, microphone technology can enhance performance for some children with CI to match that of NH peers in contexts with negative SNRs. PMID- 30278867 TI - Accounting for the Occlusion Effect with Insert Earphones. AB - BACKGROUND: There are clinical implications associated with knowing when the occlusion effect (OE) must be accounted for during bone conduction (BC) testing because spurious results can occur when errors are made in this regard. The amount of OE produced when insert earphones (IEs) are used varies in the literature; thus, further investigation is warranted. PURPOSE: The purpose of this project was to determine the OE during BC threshold measurements under the following occluding conditions used clinically: when using partial insertion (PI) versus full insertion (FI) depth and when occluding one versus both ears. RESEARCH DESIGN: A descriptive within-subjects design was used in this study. STUDY SAMPLE: Twenty-two adults with mean four-frequency pure tone averages of 24 dB HL, aged 40-83 yr, participated. INTERVENTION: BC thresholds were obtained at 250, 500, and 1000 Hz under seven conditions: (1) both ears unoccluded, (2) left ear occluded with PI, (3) right ear occluded with PI, (4) both ears occluded with PI, (5) left ear occluded with FI, (6) right ear occluded with FI, (7) both ears occluded with FI. For PI, one half of the length of the IE was beyond the opening of the ear canal. For FI, the lateral edge of the foam insert was flush with the entrance to the ear canal. DATA COLLECTION AND ANALYSIS: Mean OEs were compared with previously published data. In addition, variability in the data was examined using frequency distribution plots as well as cumulative frequency and percentile values. RESULTS: Mean OEs of 5-13 dB were present in all but the FI condition at 1000 Hz where the OE was <3 dB. Differences between PI and FI conditions were present at each frequency measured, irrespective of whether one or both ears were occluded. The shifts in threshold were consistently more prevalent and greater for the PI than the FI conditions overall. Mean differences between the one-ear and both-ears conditions were not clinically significant. Clinically significant variability in the data was noted, except when comparing the one-ear versus both ears conditions. CONCLUSIONS: Occluding the ear during initial BC measurements may artificially improve the thresholds and create or exaggerate an air-bone gap. Thus, initial BC testing should be performed unoccluded at 250, 500, and 1000 Hz. There is a need to account for the OE even when the IE is flush with the ear canal to avoid insufficient masking. PMID- 30278868 TI - Impact of Consistency in Daily Device Use on Speech Perception Abilities in Children with Cochlear Implants: Datalogging Evidence. AB - BACKGROUND: Cochlear implants (CIs) give children with severe to profound hearing loss access to sound. There appears to be a dose effect of sound exposure on speech perception abilities as shown by the positive influence of early implantation and CI experience. The consistency in device use per day could also affect sound dose, potentially affecting perceptual abilities in children with CIs. PURPOSE: The objectives of the present study were to identify the impact of consistency in device use on: (1) speech perception abilities and (2) asymmetry in speech perception abilities between bilateral CIs. RESEARCH DESIGN: Retrospective analysis. STUDY SAMPLE: To achieve the first objective, data from 65 children (age range at speech test: 1.91-18.05 yrs) with one (unilaterally implanted or bimodal) or two CIs (sequentially or simultaneously implanted) were included. A subset of data from 40 children with bilateral CIs was included to achieve the second objective. Of the 40 children with two CIs, 15 received their CIs sequentially. DATA COLLECTION AND ANALYSIS: Device use information was extracted from datalogs stored in personal speech processors using custom software. Speech perception scores per CI collected in quiet were also evaluated. Multiple regression was used to assess the impact of daily CI use, while controlling for factors previously identified to affect speech perception: age at speech test, length of pre-CI (acoustic) hearing experience, length of CI hearing experience, and order of CI for the first objective, and CI category (simultaneous/sequential implantation), interimplant delay, and length of CI experience for the second objective. RESULTS: On average, children wore their CIs for 11.59 +/- 2.86 hours/day and, with one CI, exhibited 65.07 +/- 22.64% accuracy on speech perception tests. Higher monaural speech perception scores were associated with longer everyday CI use and CI experience (p < 0.05). Among children with bilateral CIs, those with simultaneously implanted CIs and similar bilateral hearing experience demonstrated a small but significant right ear advantage with higher speech perception scores when using the right rather than left CI (mean difference = 4.55 +/- 9.83%). The asymmetry in speech perception between CIs was larger and more variable in children who received their CIs sequentially (mean difference CI1-CI2 = 27.48 +/- 24.87%). These asymmetries decreased with longer/consistent everyday use of the newer CI (p < 0.05). Yet, despite consistent everyday device use of the second CI (>12 hours/day), only a small proportion of children implanted sequentially (one out of seven children) achieved symmetrical function similar to children with simultaneously received bilateral CIs. CONCLUSIONS: Consistent everyday CI use contributes to higher speech perception scores. Although consistent CI use can help reduce the asymmetry in speech perception abilities of children with sequentially implanted CIs subsequent to interimplant delay, residual asymmetry often persists.

PMID- 30278870 TI - The Middle Latency Response: A Review of Findings in Various Central Nervous System Lesions. AB - BACKGROUND: The middle latency response (MLR) first came to light as an auditory evoked potential in 1958. Since then, it has aroused substantial interest and investigation by clinicians and researchers alike. In recent history, its use and popularity have dwindled in tandem with various other auditory evoked potentials in audiology. One area for which MLR research and application has been overlooked is its potential value in measuring the neural integrity of the auditory thalamocortical pathway. In a broader sense, the MLR, when combined with the auditory brain stem response, can provide information concerning the status of much of the central auditory system pathways. This review is intended to provide information concerning the MLR as a measure of central auditory function for the reader to consider. PURPOSE: To review and synthesize the scientific literature regarding the potential value of the MLR in assessing the integrity of the central auditory system and to provide the reader an informed perspective on the value of the MLR in this regard. Information is also provided on the MLR generator sites and fundamental characteristics of this evoked potential essential to its clinical and or research application. RESEARCH DESIGN: A systematic review and synthesis of the literature focusing on the MLR and lesions of the central auditory system. STUDY SAMPLE: Studies and individual cases were reviewed and analyzed that evidenced documented lesions of the central auditory nervous system. DATA COLLECTION AND ANALYSIS: The authors searched and reviewed the literature (journal articles, book chapters, and books) pertaining to central auditory system lesion effects on the MLR. RESULTS: Although findings varied from study to study, overall, the MLR was reasonably sensitive and specific to neurological compromise of the central auditory system. This finding is consistent with the generator sites of this evoked potential. CONCLUSIONS: The MLR is a valuable tool for assessing the integrity of the central auditory system. It should be of interest to the clinician or researcher who focuses their attention on the function and dysfunction of the higher auditory system.

AB - INTRODUCTION: Ventilator-associated pneumonia (VAP) is one of the most common healthcare-associated infections (HAI) in neonates admitted in neonatal intensive care units (NICUs). METHODS: We did a systematic review using PRISMA methodology to identify the main etiological agents in Brazilian NICUs. Eligible studies published without period restriction were identified in PUBMED, SCIELO, LILACS and DOAJ. Studies were included if they were conducted in neonates hospitalized at NICU. Studies done in outpatient care, neonates outside NICU, emergency department, primary care, long-term care facilities or a combination of these were excluded. RESULTS: We identified 6384 articles in the initial search and four papers met the inclusion criteria. In all studies included, rates of device associated infections were described, including VAP rates. The VAP incidence density, in exclusively Brazilian NICU, ranged from 3.2 to 9.2 per 1000 ventilator-days. Pneumonia was described as the main HAI in NICU in one article, as the second type of HAI in two other articles and as the fourth type of HAI in the last one. The main pathogens causing all HAI types were described in three of four articles, but, none of the articles reported which pathogens were related or associated to VAP. CONCLUSION: Etiological agents causing VAP in Brazilian NICUs are, until the present time, not known. PMID- 30278874 TI - Reply. PMID- 30278875 TI - Hemophagocytic Lymphohistiocytosis in the Elderly. AB - Hemophagocytic lymphohistiocytosis (HLH) is a rare disease of massive, dysregulated cytokine release and secondary multiorgan failure and is associated with high mortality. Primary HLH occurs predominately in infants and young children with a genetic predisposition. Acquired HLH is less well characterized and usually occurs in younger adults in the setting of severe inflammation triggered by infection or malignancy. Little is known about the disease in elderly. We report 3 patients >50 years old who presented with multiorgan failure and shock without an identifiable source and were ultimately diagnosed with acquired HLH. We performed a literature review of HLH in adults >50 years of age and identified an additional 68 cases. Mean age was 62 years, with male predominance. Most cases were triggered by infection (49%) followed by malignancy (27%). Nineteen patients were treated with the HLH-94 protocol, 11 received corticosteroids and the remainder received non-HLH specific interventions. Overall mortality was 62%.

AB - BACKGROUND: Competency-based education requires educators to use simulation training for the purposes of education and assessment of resident trainees. Research demonstrates that improvement in surgical skills acquired in a simulated environment is transferrable to the operative environment. Laparoscopic retroperitoneal dissection, opening the retroperitoneal space and identifying the ureter, is a fundamental skill for gynecologists. Integrating simulation models into a formal and comprehensive curriculum for teaching ureterolysis could translate to increased surgical competency. OBJECTIVE: Our goal was to validate a comprehensive curriculum for laparoscopic retroperitoneal dissection for the purpose of identification of the ureter by evaluating intraoperative performance. STUDY DESIGN: A comprehensive curriculum, encompassing didactic and technical skills components and using a previously developed pelvic model, was designed to teach laparoscopic ureterolysis. Novice surgeons (postgraduate years 3-5) were recruited. Participants completed precurriculum and postcurriculum multiple choice questionnaires to evaluate a didactic component. Preperformance and postperformance on the model was video-recorded. As part of the technical component, participants received constructive feedback from expert surgeons on how to perform laparoscopic retroperitoneal dissection using the simulation model. Participants were then video-recorded performing laparoscopic retroperitoneal dissection in the operating room within 3 months of the curriculum. All videos were blindly assessed by an expert using the Objective Structured Assessment of Technical Skills tool. At the conclusion of the study, participants completed a course evaluation. RESULTS: Thirty novice gynecologic surgeons were recruited. High baseline knowledge of ureteric anatomy and injury (multiple-choice question score median and interquartile range) still significantly increased from 7 (5-7.25) precurriculum to 8 (7-9) postcurriculum (P < .001). The median (interquartile range) technical Objective Structured Assessment of Technical Skills score increased significantly from 24.5 (23-28.25) precurriculum to 30 (29.75-32) postcurriculum (P < .001). Video-recordings were completed for 23 participants performing laparoscopic retroperitoneal dissection in the operating room. Intraoperative Objective Structured Assessment of Technical Skills scores (median of 29 [interquartile range 27-32]) correlated with postcurriculum Objective Structured Assessment of Technical Skills scores on the model (r = 0.53, P = .01). The ureter was identified intraoperatively by 91% (n = 21/23) of participants. The majority of residents (81%, n = 21/26) were more comfortable completing a supervised retroperitoneal dissection as a result of participating in the curriculum. Residents believed that this model would be useful to enhance skills acquisition prior to performing the skill in the operating room (65%, n = 17/26). CONCLUSION: A comprehensive retroperitoneal dissection curriculum showed improvement in cognitive knowledge and technical skills, which also translated to competent performance in the operating room. In addition to the objective measures, residents believed that their skills acquisition was improved following course completion. PMID- 30278880 TI - The emergency surgical airway: Bridging the gap from quality outcome to performance improvement through a novel simulation based curriculum. AB - BACKGROUND: Emergency surgical airway is a low frequency, high risk clinical scenario. Implementing a simulation-based curriculum may bridge the gap in surgical training and address quality assurance/performance improvement (QAPI) needs. METHODS: We designed and implemented an Advanced Surgical Airway Curriculum (ASAC) modeled after proficiency-based training. General Surgery residents and student nurse anesthetists were enrolled. Evaluation consisted of cognitive tests, procedure checklists and questionnaire. RESULTS: In total, 78 participants successfully completed the ASAC. Trainees agreed that the curriculum provided the cognitive and psychomotor skills necessary to perform both an open and needle cricothyroidotomy. CONCLUSIONS: In the age of increased patient safety concerns, QAPI initiatives can serve as a driver for simulation-based training curricula, with particular focus on individualized, active learning. This may be particularly useful in high risk, low frequency scenarios in which the traditional method of "See one, Do one, Teach one," is not feasible.

AB - Genetic instability is one part of the oncogenic process. Gene mutations involved in DNA repair mechanisms can promote this genetic instability and participate in oncogenesis and metastatic progression. In prostate cancer, DNA repair abnormalities mainly correspond to somatic or constitutional mutations of the BRCA2 and ATM genes. Therapeutic management of metastatic castration-resistant prostate cancer (mCRPC) is currently based on new hormonal therapies (abiraterone, enzalutamide) and taxane-type chemotherapy (docetaxel or cabazitaxel). Preliminary data tend to indicate a specific activity of agents causing DNA breaks (platinum salts) and PARP inhibitors in patients with these DNA repair abnormalities. The frequency of DNA repair gene mutations in patients with prostate cancer (around 20%) and the antitumor response of PARP inhibitors make it a possible short-term therapeutic strategy with several registering clinical trials ongoing. PMID- 30278884 TI - Long noncoding RNA LOXL1-AS1 regulates prostate cancer cell proliferation and cell cycle progression through miR-541-3p and CCND1. AB - Prostate cancer is one of the most frequent malignancies affecting men. Long non coding RNAs (lncRNAs) are involved in the pathogenesis of prostate cancer. LncRNA LOXL1-AS1 participates in the pathogenesis of the exfoliation syndrome. However, the role of LOXL1-AS1 in cancer remains largely unknown. Here, we found that LOXL1-AS1 down-regulation inhibited prostate cancer cell proliferation and cell cycle progression. RNA sequencing analysis revealed that it regulates the expression of cell cycle-related genes. LOXL1-AS1 is predominantly distributed in the cytoplasm, where it interacts with miR-541-3p. In addition, miR-541-3p targets the cell cycle regulator CCND1 in prostate cancer cells. LOXL1-AS1 down regulation inhibits the expression of CCND1 and cell cycle progression, whereas these effects are abolished upon miR-541-3p suppression. In summary, our study revealed that LOXL1-AS1 regulates prostate cancer cell proliferation and cell cycle progression through miR-541-3p and CCND1. Modulation of their levels may be used to treat prostate cancer. PMID- 30278885 TI - BAF53A regulates androgen receptor-mediated gene expression and proliferation in LNCaP cells. AB - The actin-like protein of the SWI/SNF complex, BAF53A, regulates gene expression by the gene-specific chromatin remodeling of target genes. However, the function of BAF53A in the androgen receptor pathway in prostate cancer cells remains unclear. Here, we demonstrated that BAF53A positively regulates the expression of endogenous AR target genes (e.g. PSA, TMPRSS2, FKBP5, and KLK2) in LNCaP cells. It functions as a coactivator in AR-mediated transcription by interacting with other nuclear receptor coactivators, such as p300 and FLII, and is associated with AR in the presence of dihydrotestosterone (DHT). The DHT-induced recruitment of BAF53A to the proximal and distal androgen response elements (AREs) of the PSA gene in the presence of BRG1 (but not BRM) was inhibited by an AR antagonist, suggesting the coactivator function of BAF53A in the SWI/SNF complex. Depletion of BAF53A in LNCaP cells resulted in a significant decrease in growth rate. Furthermore, the expression of BAF53A in prostate cancer tissue was significantly elevated, compared to that in normal prostate tissue, and correlated with the expression of AR, and BRG1, but not BRM. Therefore, our results suggested that BAF53A plays an important role in the expression of AR target genes in prostate cancer, and can be used clinically for the treatment of prostate cancer. PMID- 30278886 TI - Selective toxicity of caffeic acid in hepatocellular carcinoma cells. AB - Caffeic acid is a natural phytochemical structurally similar to other cinnamic acids. In this study we found caffeic acid (CA) but not ferulic, sinapic or cinnamic acids inhibited proliferation of hepatocellular carcinoma cells (HCC) and reduced cell numbers by inducing apoptosis. Only transient exposure to CA was required for these lethal effects that are associated with disruption of mitochondrial membrane potential and induction of reactive oxygen species. By comparison, primary hepatocytes resisted CA toxicity for nearly 48 h, consistent with selective sensitivity of HCC to CA. These results support use of CA as an anti-tumor agent to inhibit HCC, especially if delivered by locoregional catheterization in an embolization procedure. PMID- 30278887 TI - Ferricrocin, the intracellular siderophore of Trichoderma virens, is involved in growth, conidiation, gliotoxin biosynthesis and induction of systemic resistance in maize. AB - Fungal siderophores are known to be involved in iron acquisition and storage, as well as pathogenicity of mammals and plants. As avirulent plant symbionts, Trichoderma spp. colonize roots and induce resistance responses both locally and systemically. To study the role of intracellular siderophore(s) in Trichoderma plant interactions, we have obtained mutants in a non-ribosomal peptide synthetase, TvTex10, that was predicted to be involved in intracellular siderophore(s) biosynthesis. This gene has a detectable basal level of expression and is also upregulated under iron-deplete conditions. This is unlike two other siderophore-encoding genes, which are tightly regulated by iron. Disruption of tex10 gene using homologous recombination resulted in mutants with enhanced growth rate, reduced conidiation and hyper-sensitivity to oxidative stress as compared to wildtype strain. The mutants also produced reduced levels of gliotoxin and dimethyl gliotoxin but have enhanced ability to colonize maize seedling roots. The mutants were also impaired in induction of induced systemic resistance (ISR) in maize against the foliar pathogen Cochliobolus heterostrophus. PMID- 30278888 TI - Maternal supplementation with calcium varying with feeding time daily during late pregnancy affects lipid metabolism and transport of placenta in pigs. AB - To investigate effects of Ca level varying with feeding time daily in sows during late pregnancy on placental lipid metabolism and transport in pigs, sixty pregnant sows were assigned to 3 groups: the CON group was fed low-Ca diet with 11.25 g CaCO3 at 0600 h and 1500 h, H-L group was fed low-Ca diet with 22.5 g CaCO3 at 0600 h and low-Ca diet at 1500 h, and L-H group was fed low-Ca diet at 0600 h and low-Ca diet with 22.5 g CaCO3 at 1500 h, respectively. Serum from sows and umbilical cord and placenta were collected during delivery. Results showed that, compared with the CON group, H-L feeding significantly increased maternal serum total triglyceride (TG) and umbilical serum high-density lipoprotein (HDL) (P < 0.05). The results showed that long chain fatty acid (FA) contents in placenta were significantly increased in H-L and L-H groups (P < 0.05). Experiments on genes involved in glycolipid metabolism showed that H-L or L-H feeding inhibited mRNA expression of GLUT3, GLUT4, FAS, FABP1, FABPpm, FAT/CD36, while activated the mRNA expression of FASD1, FASD2 and SCD in placenta (P < 0.05). In addition, experiments on genes involved in biological clock showed that L-H feeding sequence activated the mRNA expression of per1 and clock, while H-L and L-H feeding sequence inhibited mRNA expression of per2 in placenta (P < 0.05). It is concluded that maternal supplementation with Ca varying with feeding time daily during late pregnancy affects placental lipid metabolism and transport in pigs by regulating the mRNA expression related to lipid metabolism and the circadian clock. PMID- 30278889 TI - Natural deep eutectic solvents-mediated extractions: The way forward for sustainable analytical developments. AB - The concept of sustainable development has impacted in analytical chemistry changing the way of thinking processes and methods. It is important for analytical chemists to consider how sample preparation can integrate the basic concepts of Green Chemistry. In this sense, the replacement of traditional organic solvents is of utmost importance. Natural Deep Eutectic Solvents (NADES) have come to light as a green alternative. In the last few years, a growing number of contributions have applied these natural solvents proving their efficiency in terms of extraction ability, analyte stabilization capacity and detection compatibility. However, the arising question that has to be answered is: the use of NADES is enough to green an extraction process? This review presents an overview of knowledge regarding sustainability of NADES-based extraction procedures, focused on reported literature within the timeframe spanning from 2011 up to date. The contributions were analyzed from a green perspective in terms of energy, time, sample and solvent consumption. Moreover, we include a critical analysis to clarify whether the use of NADES as extraction media is enough for greening an analytical methodology; strategies to make them even greener are also presented. Finally, recent trends and future perspectives on how NADES-based extraction approaches in combination with computational methodologies can contribute are discussed. PMID- 30278890 TI - Sensitive DNA detection by polymerase chain reaction with gold nanoparticles. AB - We developed a novel strategy for rapid colorimetric detection of specific DNA sequence based on gold nanoparticles assemblies induced by polymerase chain reaction (PCR) product. In the presence of target DNA, the two DNA-functionalized AuNP probes selectively hybridized with the prohibited nucleic acid segments of two primers owing to the zipping off of the hairpin structures during PCR process, resulted in the aggregation of AuNPs with a concomitant color change from red to blue-purple. It is a convenient and universal method for sensitive DNA detection with no need for any further post-treatment of the PCR products. Most importantly, our method showed a low limit of detection (LOD) of 4.3 fM with a wide range of target DNA from 16 fM to 1.6 nM. Owing to the versatility and low cost, the proposed strategy could be extremely useful for a wide range of applications, providing a promising tool for rapid disease diagnostics and gene sequencing. PMID- 30278891 TI - A novel enzyme-free glucose and H2O2 sensor based on 3D graphene aerogels decorated with Ni3N nanoparticles. AB - In this work, a novel enzyme-free glucose and hydrogen peroxide (H2O2) sensor based on Ni3N nanoparticles on conductive 3D graphene aerogels (Ni3N/GA) has been successfully synthesized by using hydrothermal reaction, freeze-dried and then calcined under NH3 atmosphere. The obtained Ni3N/GA composites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), nitrogen adsorption-desorption isotherms and electrochemical methods. The results show the obtained 3D Ni3N/GA composites exhibit excellent electrochemical performance toward glucose oxidation and H2O2 reduction with larger catalytic rate constant Kcat value of 3.75 * 103 M-1 s -1 and 1.24 * 103 M-1 s -1, respectively. As a glucose sensor, the obtained electrode provides a wide detection range of 0.1 7645.3 MUM, fast response time within 3 s, high sensitivity of 905.6 MUA mM-1 cm 2 and low detection limit of 0.04 MUM. For detection of H2O2, this prepared sensor offers a wide detection range (5 MUM-75.13 mM), fast response time (within 5 s), sensitivity (101.9 MUA mM-1 cm-2) and low detection limit (1.80 MUM). This enzyme-free glucose and H2O2 sensor display satisfactory selectivity, reproducibility and long-term storage stability. Additionally, the sensor can also be used for glucose and H2O2 detection in human blood serum. The results demonstrate that 3D GA nanostructures provide an enviable conductive network for efficient charge transfer and avoid Ni3N nanoparticles aggregation, which is advantageous for electrocatalytic applications. PMID- 30278892 TI - Dual-mode fluorescent and colorimetric immunoassay for the ultrasensitive detection of alpha-fetoprotein in serum samples. AB - We present a novel dual-mode fluorescent and colorimetric immunosensor based on conventional immunoassay platforms by utilizing a gold nanoflower (AuNF)-loaded fluorescein molecule (AuNF@Fluorescein) as signal output. The AuNFs were modified with thiolated carboxyl ligand, which consisted of a hydrophobic alkane chain as hydrophobic wallet for fluorescein encapsulation, a tetra (ethylene glycol) unit for biocompatibility and solubility, and a functional carboxyl group for the conjugation of biorecognition molecules for biosensing. The resultant AuNFs showed a high loading capacity of 3.74 * 106 fluorescein molecules per AuNF because of its flower-like shape with many complex branches. By adjusting the solution pH to 8.0, the fluorescein molecules can almost entirely be released from the hydrophobic wallet of AuNF@Fluorescein, which led to strong fluorescent signal amplification. Under the optimal detection conditions, the proposed immunoassay based on fluorescent signal exhibited ultrahigh sensitivity for alpha fetoprotein (AFP) detection, with a limit of detection (LOD) of 29 fg/mL. This value is approximately 9.3 * 103-fold lower than that of corresponding horseradish peroxidase (HRP)-based immunoassay (LOD = 270 pg/mL). The fluorescein molecule also had intrinsic peroxidase-like activity to catalyze 3,3',5,5' tetramethylbenzidine oxidation with hydrogen peroxide for colorimetric signal. The proposed method with colorimetric mode further exhibited a sensitivity with a LOD of 17.7 pg/mL, which is about 15-fold lower than that of conventional HRP based immunoassay. The recoveries of the proposed dual-mode immunoassay for AFP spiked serum samples ranged within 89.85%-100.0%, with the coefficient of variations ranging from 0.5% to 2.4%, indicating acceptable accuracy and precision for AFP quantitative detection. The reliability of the developed dual mode immunoassay was further compared with a commercial chemiluminescence immunoassay kit by analyzing 20 clinical serum samples, showing that the two methods well agreed with each other, with high correlation coefficients of 0.997 and 0.986 based on recorded fluorescence and colorimetric signals, respectively. In summary, the proposed method was highly suitable for the ultrasensitive analysis of biomarkers or infectious diseases by fluorescence mode and can be used for routine clinical diagnosis by colorimetric mode. PMID- 30278893 TI - A simple and sensitive fluorescence method for detection of telomerase activity using fusion protein bouquets. AB - Telomerase is considered as a widely accepted cancer biomarker for early cancer diagnostics. Herein, we develop a simple, ultrahigh sensitivity method for detection of telomerase activity, which relied on that RecA-GFP fusion proteins wrapped around telomeric DNA to form fluorescence bouquets. RecA-GFP fusion protein was synthesized through fusion protein technology. In the presence of telomerase, telomerase elongation products are wrapped around by RecA-GFP fusion protein to form big fluorescent bouquets, which resulted in strong fluorescence. This method has the linear range from 50 to 1000 HeLa cells and the detection limit is 8 HeLa cells, based on a signal-to-noise ratio (S/N) of 3. Compared with conventional methods, this method has the advantages of low toxicity, outstanding sensitivity, and excellent selectivity. Hence, it provides a promising approach for the detection of telomerase activity and diagnosis of cancer. PMID- 30278894 TI - Aptamer proximity recognition-dependent strand translocation for enzyme-free and amplified fluorescent detection of thrombin via catalytic hairpin assembly. AB - By coupling a new aptamer proximity recognition-dependent strand translocation strategy with catalytic hairpin assembly (CHA) signal amplification, we have developed a simple and sensitive method for detecting thrombin in human serums. Simultaneous binding of two engineered aptamer probes to the thrombin target significantly increases the local concentrations of the two probes and facilitates the translocation of a ssDNA strand from one of the probes to the other through toehold mediated strand displacement. Such a strand translocation leads to the generation of a ssDNA tail in the aptamer sequence for subsequent initiation of the assembly of two fluorescently quenched hairpins into many DNA duplexes via CHA. The formation of the DNA duplexes thus results in significant fluorescence recovery for amplified detection of thrombin down to 8.3 pM. The developed method is highly selective to the thrombin target against other interference proteins due to the dual recognition mode, and can be employed to monitor thrombin in human serum samples. With the advantage of simplicity, sensitivity and selectivity, this method can be a universal non-enzymatic and nanomaterial-free amplified sensing platform for detecting different protein molecules. PMID- 30278895 TI - Fabricating carbon-nanotubes-based porous foam for superoxide electrochemical sensing through one-step hydrothermal process induced by phytic acid. AB - The detection of superoxide anions (O2*-) is widely considered as a potential way for cancer diagnosis and the development of enzyme-mimic catalysts is the main challenge in the establishment of electrochemical sensors for O2*- sensing in real samples. Here we present a novel enzyme- and metal-free electrochemical catalyst for superoxide (O2*-) sensing based on the widely-used carbon nanotubes (CNT). Through a one-step hydrothermal process induced by phytic acid (PA), CNT based porous foam (PACNTF) was successfully obtained. Characterizations demonstrated the enhanced defect and disorder degree of PACNTF after PA treatment, which leaded to the increased active sites of PACNTF for electron transfer and the adhesion of O2*- during the electrochemical process. As a result, the PACNTF presented higher conductivity and larger current response toward O2*- sensing when compared with CNT precursor and CNTF without PA treatment. The sensitivity of PACNTF/SPCE was calculated to be 1230 MUA cm-2 mM-1 in the linear range of 0-193.6 MUM (R2 = 0.965) and 373 MUA cm-2 mM-1 in the linear range of 193.6-1153.6 MUM (R2 = 0.995) with a limit of detection of 0.16 MUM (S/N = 3). Further, the PACNTF/SPCE presented fast response toward cell released O2*- stimulated by Zymosan A. The above results indicated that the fabricated sensor holds potential usage in biological samples. PMID- 30278896 TI - Hairpin-structured probe conjugated nano-graphene oxide for the cellular detection of connective tissue growth factor mRNA. AB - Identification of abnormal scars at their early stage has attracted increasing attentions as the scars can only be assessed qualitatively and subjectively upon maturity, when no invasive procedure is involved. This report introduces a fluorescent probe that targets a potential abnormal scar biomarker (connective tissue growth factor (CTGF) mRNA) in skin fibroblasts. This probe is constructed of hairpin-structured probes (HPs) targeting CTGF mRNA and the nano-graphene oxide (nano-GO) base. The HPs are non-covalently absorbed on the surface of nano GO, which pre-quenches the fluorescence of HPs. Close proximity of complementary CTGF mRNA would lead to preferential HP hybridization and dissociation from nano GO, which restores the fluorescence signal from HPs. Utilizing this probe, we can distinguish abnormal fibroblasts derived from abnormal scars and assess the effectiveness of anti-scarring drugs like Repsox and transforming growth factor beta type I receptor (TGF-betaRI) siRNA. PMID- 30278897 TI - Fluorescent/SERS dual-sensing and imaging of intracellular Zn2. AB - A fluorescent and surface-enhanced Raman spectroscopy (SERS) dual-mode probe is developed for imaging of intracellular Zn2+ based on N-(2-(bis(pyridine-2 ylmethyl)amino)ethyl)-2-mercaptoacetamide (MDPA) modified gold nanoparticles (MDPA-GNPs). Benefiting from the chelation-enhanced fluorescence (CHEF) between MDPA-GNPs and Zn2+, the fluorescent intensities of MDPA-GNPs are substantially enhanced with the increment of Zn2+ concentrations, which can be clearly observed by the naked eye. Under physiological conditions, the probe exhibits a stable response for Zn2+ from 1 MUM to 120 MUM, with a detection limit of 0.32 MUM in aqueous solutions. The resultant MDPA-GNPs can be used for ultrasensitive SERS detection of Zn2+ because of the strong inter-particle plasmonic coupling generated in the process of Zn2+-triggered MDPA-GNPs self-aggregation, with a low detection limit of 0.28 pM, which is eight order of magnitude lower than the United States Environmental Protection Agency (US EPA)-defined limit (76 MUM) in drinkable water. More importantly, the proposed probe can be applied for efficient detection of intracellular Zn2+ with excellent biocompatibility and cellular imaging capability. Therefore, a highly sensitive and selective nanosensor has been demonstrated for both reliable quantitative detection of Zn2+ in aqueous solution and real-time imaging of intracellular Zn2+, suggesting its significant potential utility in bioanalysis and biomedical detection in the future.

AB - Determining methylation state of a particular DNA sequence is an essential task in many epigenetic investigations. Here a facile method based on silver nanocluster (AgNCs) fluorescence enhancement is presented. Target sequences were selected from Sept9 promoter region that its hypermethylation is demonstrated as a reliable biomarker of colorectal cancer. Probe DNA was complementary to a 25 nucleotide of the target region and possessed twelve additional cytosines in the middle to grant the formation of AgNCs. After probe strands were hybridized with methylated and non-methylated targets separately, AgNCs were synthesized, and their fluorescence intensities were recorded. Fluorescence intensity enhanced when the target strands were methylated and quenched when they were non methylated. The Linear range of fluorescence enhancement was from 1.0 * 10-7 M to 5.0 * 10-7 M with the detection limit of 7.6 * 10-8 M. Sensor specificity was checked with non-complementary strands with the maximum similarity of 40%. Further experiments explored various characteristics of methylated and non methylated DNAs carrying AgNC and indicated that structure of methylated and non methylated DNAs was affected differently by silver ions that could then influence AgNC fluorescence. This effect was strongly sequence-dependent, and either fluorescence enhancement or quenching was observed with two different sequences.

AB - The detection of single nucleotide polymorphisms (SNPs) is of great clinical significance to the diagnosis of various genetic diseases and cancers. In this work, the development of an ultrasensitive ratiometric electrochemical sensor for screening SNP with a significantly enhanced discrimination factor is reported. The ferrocene (Fc) and methylene blue (MB) dual-tagged triple helix complex (THC) probes are self-assembled on the gold electrode to construct the sensing interface. The addition of the mutant p53 gene causes the disassembly of the THC probes with the release of the Fc-tagged sequence and the folding of the MB labeled sequence into a hairpin structure, causing the change in the current response ratio of MB to Fc for monitoring the mutant p53 gene. Such ratio is dramatically enhanced by the toehold-mediated displacement reaction-assisted target recycling amplification with the presence of an assistance hairpin sequence. With the significant signal amplification and the advantageous specificity of the THC probes, sub-femtomolar detection limit and a highly enhanced SNP discrimination factor for the mutant p53 gene can be obtained. Besides, the proof-of-demonstration application of the sensor for diluted real samples has been verified, offering such sensor new opportunities for monitoring various genetic related diseases. PMID- 30278900 TI - Non-SELEX isolation of DNA aptamers for the homogeneous-phase fluorescence anisotropy sensing of tau Proteins. AB - Herein, we report for the first time the isolation of DNA aptamers directed against the whole tau protein, an important Alzheimer's disease (AD) biomarker. Non-SELEX approach based on the capillary electrophoresis partitioning technique was employed to isolate a high-affinity DNA sequence pool towards the target in only three rounds and one working day. High-throughput sequencing was next performed and the recognition ability of five selected aptamers was preliminary evaluated by surface plasmon resonance using the protein target immobilized on the chip. Finally, the analytical potential of the most affine aptamer was demonstrated through the design of a homogeneous-phase fluorescence anisotropy assay. This DNA aptamer was found to be able to recognize not only the whole tau 441 but also the tau-381, tau-352, tau-383 isoforms. The sensing platform allowed the determination of these four targets with a detection limit of 28 nM, 3.2 nM, 6.3 nM and 22 nM, respectively. PMID- 30278901 TI - SPE-LC-MS investigations for the isolation and fractionation of acidic oil degradation products. AB - In this study, we focus on isolation and fractionation strategies by solid phase extraction (SPE) for a broad range of environmentally related organic acids. These emerging potential contaminants are primary degradation products of spilled petrogenic compounds but little attention has been given to their environmental analysis and risk assessment. Three mixed-mode anion exchange sorbents possessing various backbone polarities were compared with respect to the extraction and fractionation efficiency. Quantitative analysis was obtained using an optimized and validated LC-MS method. We demonstrated the importance of reasonable ion source settings for highest sensitivity of individual carboxylic acids. Furthermore, fractionation of carboxylic acids into aliphatic and aromatic fractions by SPE was achieved by step-wise elution. Best performance regarding the isolation of low-concentration acids (sub MUg L-1 level) in complex samples was attributed to Strata XA and is caused by high secondary hydrophobic interactions in addition to the ionic interactions. Isolation and fractionation of acid spiked diesel-spilled harbor water (22 MUg L-1 spike level) revealed recoveries >80% for all tested carboxylic acids and low carry-overs of neutral petroleum compounds. We conclude that the isolation and fractionation of acidic degradation products by SPE is a powerful tool to investigate this new class of contaminants in relation to identification and ecological risk assessments.

AB - A fast and simple supercritical fluid chromatography method for the enantioseparation of twenty newly synthesized orthoconic antiferroelectric liquid crystals is reported for the first time. The effects of alkoxy spacer length and fluorine atom presence and position in the phenyl ring on chromatographic behavior were investigated. Baseline enantioseparation of all compounds was achieved using simple mobile phases consisting of carbon dioxide and alcohol as cosolvent on (3,5-dimethylphenylcarbamate) derivative of amylose as chiral stationary phase. The analysis times ranged from 2 to 4 and from 4 to 7 min for most samples when using methanol and propane-2-ol, respectively. The significant effect of cosolvent type on the enantioseparation of these compounds was assessed and partial complementarity of methanol and propane-2-ol was observed. PMID- 30278903 TI - Macro-mesoporous organosilica monoliths with bridged-ethylene and terminal-vinyl: High-density click functionalization for chromatographic separation. AB - A novel kind of macro-mesoporous organosilica monolith, with not only bridged ethylene groups incorporated into the skeleton but also terminal-vinyl groups protruded from the pore-wall, was prepared so that high-loaded double bonds were achieved. Via highly efficient "thiol-ene" click reaction of such high-loaded double bonds, the surface coverage of C18 groups on monolith could be 5.54 MUmol m-2, significantly larger than that of the reported separation materials, beneficial to improvement of separation resolution, especially for peptide separation. The separation performance was evaluated using alkylbenzenes and standard peptides. Furthermore, the tryptic digests of complex sample was successfully analyzed. Because of high separation resolution of our prepared hybrid monolith, the peak capacity for 6-h gradient was achieved as 482. Coupling to LTQ Orbitrap Velos Mass Spectrometry, 22523 tryptic peptides from 4423 proteins were identified from the HeLa cells, more than that using the other long gradient separation by the same system reported, showing great promising of such monolith for large-scale in-depth proteomic analysis. PMID- 30278904 TI - Ultrasensitive and label-free electrochemical aptasensor of kanamycin coupling with hybridization chain reaction and strand-displacement amplification. AB - This work reports the proof-of-concept of an ultrasensitive label-free electrochemical aptasensor for Kanamycin (Kana) detection coupling strand displacement amplification (SDA) with hybridization chain reaction (HCR). In the presence of target Kana, the analyte triggers conformational change of hairpin HP1 (HP1) and two-staged SDA to produce short single-stranded DNA (S1) with the aid of KF polymerase and nicking endonuclease. Meanwhile, the as-produced S1 hybridizes with the immobilized hairpin HP2 (HP2) on the electrode to open the hairpin, thereby resulting in the formation of DNA duplex. Thereafter, DNA duplex is selectively digested by Exo III accompanying S1 recycling. The residual single stranded probe (S2) on the electrode opens another two hairpins in sequence and propagates a chain reaction of hybridization events between two alternating hairpins (H1 and H2) to form a long nicked double-helix. Upon addition of redox active methylene blue (MB), numerous indicators are intercalated into the grooves of double-helix DNA polymers, each of which produces an electrochemical signal within the applied potentials. Under optimum conditions, the SDA/HCR-based electrochemical aptasensor exhibits a high sensitivity for detection of Kana down to 36 fM with a linear range from 0.05 to 200 pM. Additionally, the as-prepared aptasensor is successfully employed to determinate the Kana in animal derived food (milk). With the advantages of high sensitivity, label-free strategy and excellent selectivity, the developed aptasensor possesses great potential application value in food-safety analysis field. PMID- 30278905 TI - epsilon-MnO2-modified graphite electrode as a novel electrochemical sensor for the ultrasensitive detection of the newly FDA approved Hepatitis C antiviral drug ledipasvir. AB - A novel, simple and sensitive electrochemical method for the determination of ledipasvir (LED), the newly FDA approved Hepatitis C antiviral drug was developed and validated using epsilon-MnO2-modified graphite electrode. Two different MnO2 polymorphs (gamma- and epsilon-MnO2 nanoparticles) were synthesized and characterized using X-ray powder diffraction (XRD), Fourier transform infrared (FTIR), energy dispersive X-ray (EDX) and thermogravimetric analysis (TGA). Surface area measurements show that epsilon-MnO2 NPs have large surface area of 345 m2/g, which is extremely high if compared to that of gamma-MnO2 NPs (38 m2/g). In addition, a comprehensive study of the difference in the electrochemical behavior of LED while using pencil graphite electrode (PGE) modified with either gamma- or epsilon-MnO2 NPs is carried out. It was found that surface area and percentage of surface hydroxyls of MnO2 NPs are the key factors governing the sensitivity of the fabricated electrode toward the oxidation of the positively charged LED. Scanning electron microscopy (SEM) was employed to investigate the morphological shape of MnO2 NPs and the surface of the bare and modified electrodes. Moreover, cyclic voltammetry and electrochemical impedance spectroscopy (EIS) were used for the surface analysis of the modified electrodes. Based on the obtained results, epsilon-MnO2/PGE was applied as a selective and sensitive electrode for determination of LED. Under the optimized experimental conditions, epsilon-MnO2/PGE provides a linear response over the concentration range of 0.025-3.60 MUmol L-1 LED with a low limit of detection, which was found to be 5.10 nmol L-1 (4.50 ng mL-1) for the 1st peak and 9.20 nmol L-1 (8.10 ng mL 1) for the 2nd one. In addition, the oxidation behavior of LED is discussed with a full investigation of the oxidized product using FT-IR and LC/MS. The fabricated sensor exhibits a good precision, selectivity and stability and was applied successfully for the determination of LED in its tablets and real rat plasma samples with a good recovery using a simple extraction technique. PMID- 30278906 TI - Nitrogen doped chiral carbonaceous nanotube for ultrasensitive DNA direct electrochemistry, DNA hybridization and damage study. AB - In the interest of developing novel electrocatalyst for high performance DNA biosensing, with distinctive chiral double helix nanostructure, nitrogen doped chiral carbonaceous nanotube (Chiral-CNT) was employed for ultrasensitive label free DNA biosensing research. Chiral-CNT can quantitative detection of four DNA bases with high sensitivity and selectivity. Without any prehydrolysis and labeling process, direct electrochemistry of single-stranded DNA and double stranded DNA, qualitative and quantitative detection of DNA hybridization (low detection limit: 0.0268 g L-1) were realized. Moreover, sensitive detection of DNA damage induced by fenton reagent was also realized with low detection limit of 0.0350 mg mL-1 and high sensitivity of 7.42 MUA mg-1 mL. The high biosensing performance attributes to the unique chiral structure of Chiral-CNT, leads to efficient interreaction between Chiral-CNT and DNA molecule. PMID- 30278907 TI - Development of a cobalt(II) phthalocyanine- MWCNT modified carbon paste electrode for the detection of polyunsaturated fatty acids. AB - In this work the development of an electrochemical sensor for the determination of polyunsaturated fatty acids (PUFAs), in particular linoleic acid, in commercially available safflower oil as complex matrix is described. The sensor consists of a carbon paste electrode with cobalt(II) phthalocyanine, Co(II)Pc, as mediator and multiwalled carbon-nanotubes (MWCNT) as nanomaterial. As carrier medium a sodium borate buffer (0.1 M, pH 9) was used. PUFAs were detected at a working voltage of 0.35-0.45 V (vs. Ag/AgCl). The sensor development was carried out in a batch system with differential pulse voltammetry (DPV) and cyclic voltammetry (CV). Sensor specification was tested by using various fatty acids (stearic acid, oleic acid, linoleic acid, linolenic acid and arachidonic acid) as well as esterified fatty acids, resulting in a specific applicability towards PUFAs, especially linoleic acid (LAH). The optimized sensor was applied in a flow injection analysis system (FIA) for the analysis of PUFAs in complex matrix. Linoleic acid was used as standard substrate to determine the analytical parameters. The linearity ranges between 7.5 and 200 MUg mL-1 LAH, while the limit of detection was determined to be 2.5 MUg mL-1 and the limit of quantification is approximately 7.5 MUg mL-1 LAH. The LAH content was successfully detected in commercially available safflower oil via standard addition method and the results could be confirmed by a reference method. The PUFA content was calculated as LAH-equivalent. PMID- 30278908 TI - A novel gas sampling introduction interface for fast analysis of volatile organic compounds using radiofrequency pulsed glow discharge time of flight mass spectrometry. AB - An improved gas sample introduction interface is developed and characterized for gas chromatography coupling and for direct injection of volatile organic compounds (VOCs), in a pulsed glow discharge (pulsed-GD) ion source coupled to a time of flight mass spectrometer (TOFMS) that is typically used for direct solid analysis. The novel interface allows the introduction of the analytes in the flowing afterglow region of the GD (a few mm away from the negative glow region) to reduce plasma quenching effects. Analyte ion signals are acquired in the temporal afterglow region, where low fragmentation of the molecular species is produced, providing useful qualitative and quantitative molecular information (e.g. molecular ion). Analytical capabilities of the pulsed-GD ion source with the novel gas sampling interface provides improved performance compared to previous designs. In particular, limits of detection for the analysis of VOCs in air were below (better) that legally established limits according to Directive 2008/50/EC of the European Parliament. PMID- 30278909 TI - New approach for e-cigarette aerosol collection by an original automatic aerosol generator utilizing melt-blown non-woven fabric. AB - Currently, there is lack of standardized conditions for the collection and analysis of e-cigarette (EC) aerosol. Considering the urgent need for the development of these guidelines, a procedure for EC aerosol analysis was developed. A novel automatic e-cigarette aerosol generator was designed. For the first time, melt-blown non-woven fabric was applied for the effective uptake of compounds released from vaporized e-liquid. The extraction procedure was optimized in terms of type of extraction solvent, amount of sorbent and solvent volume. For optimization, a model e-liquid containing flavour additives belonging to various chemicals group with various chemical properties was investigated. The aerosol trapping efficiency was satisfactory and was equal to 92 +/- 7%. Final determination was performed by GC-MS/MS. Quantitation was based on the mass change tracking approach (MCT), which assumes the monitoring of e-liquid mass changes before and after vaping. The combination of non-woven fabric and sampling approach (MCT) was proven to be effective in acquisition of reliable data. Thus, the concentrations in aerosol and emission factors were calculated for aerosols collected during the vaping of both model e-liquids and real samples. Validation was performed by evaluating key analytical parameters, such as linearity, accuracy, precision, limit of detection (LOD) and quantitation (LOQ). For all investigated compounds, recoveries from 70% to 118% together with precision and reproducibility below 12% were achieved. The applicability of the described approach was examined by analysing EC refill solutions commercially available on the Polish market. PMID- 30278910 TI - Design of an ultrasonic piezoelectric injection port for analysis of thermally unstable compounds using corona discharge ion mobility spectrometry. AB - This paper reports on a novel ultrasonic injection port designed and constructed to analyze thermally unstable chemical compounds using corona discharge ion mobility spectrometry (CD-IMS). In order to achieve the highest possible efficiency with the device, some parameters such as the solvent type, carrier gas flow rate and sample volume were exhaustively investigated. Through a comparative study conducted, it was revealed that unlike the thermal desorption system, the proposed ultrasonic injection port could easily be used for the analysis of some thermally unstable compounds such as carbaryl, propoxur and vitamin B1, by means of CD-IMS. To evaluate the potential of the device, carbaryl, extracted from different samples by dispersive liquid-liquid microextraction technique, was quantitatively analyzed. The CD-IMS-based results brought forth the detection limit of 0.03 mg L-1, and dynamic range of 0.1-10.0 mg L-1 with the determination coefficient of 0.9981. The relative standard deviations for one day and three consecutive days were 4 and 6%, respectively. Further, the spiked samples of agricultural wastewater, underground water, and tomato analyzed culminated in the recovery values of 83%, 98% and 82%, respectively. The satisfactory results proved an acceptable capability of the sample introduction system, to be conveniently used for routine analysis of thermally unstable compound, without any tedious derivatization. PMID- 30278911 TI - Hypersensitive quantification of global 5-hydroxymethylcytosine by chemoenzymatic tagging. AB - 5-hydroxymethylcytosine (5hmC) is an epigenetic DNA modification. Tissue-specific reduction in global 5hmC levels has been associated with various types of cancer. One of the challenges associated with detecting 5hmC levels is its extremely low content, especially in blood. The gold-standard for reliable global 5hmC quantitation is liquid chromatography-tandem mass spectroscopy (LC-MS/MS) operating in a multiple reaction monitoring (MRM) mode. Difficulties associated with 5hmC detection by LC-MS/MS include its low abundance, low ionization efficiency and possible ion suppression from co-eluted compounds. Hence, detecting 5hmC levels in blood samples for diagnosis of leukemia and other blood malignancies presents a unique challenge. To overcome these difficulties we introduce a simple chemoenzymatic method for specifically tagging 5hmC, resulting in an eight-fold increase in detection sensitivity. We demonstrate that we could quantitatively detect 5hmC levels in various human tissues, including blood samples from healthy individuals and leukemia patients, using the most basic quadrupole mass-analyzer instrument and only 200 ng of DNA. The limit of detection (LOD) of our technique is 0.001% 5hmC from 300 ng DNA, sufficient for future mass-spectroscopy based diagnostics of diseases associated with low 5hmC levels such as leukemia. PMID- 30278912 TI - Core-shell red silica nanoparticles based immunochromatographic assay for detection of Escherichia coli O157:H7. AB - In this paper, a new type immunochromatographic assay (ICA) based on core-shell red silica nanoparticles (core-shell red SiO2NPs) was proposed and used to detect Escherichia coli O157:H7 (E. coli O157:H7). This is the first report of qualitative ICA for detecting E. coli O157:H7 in phosphate buffer saline (PBS) and food sample using core-shell red SiO2NPs. Monodispersed red SiO2NPs were synthesized in the aqueous solution by modifying amino silane and C.I Reactive Red 136 on unmodified silica nanoparticles. The limit of detection (LOD) of this core-shell red SiO2NPs based ICA for E. coli O157:H7 was 4.5 * 105 CFU/mL in sterile PBS within 20 min. The LOD of this ICA strip for E. coli O157:H7 in milk and pork samples both were 4.5 * 106 CFU/mL. The core-shell red SiO2NPs based ICA for detection of E. coli O157:H7 has no cross activity with other bacteria. All these results show that this new kind of core-shell colored SiO2NPs is promising for the practical applications in ICA and other rapid detection fields. PMID- 30278913 TI - Rapid Access Cardiology (RAC) Services Within a Large Tertiary Referral Centre First Year in Review. AB - BACKGROUND: Rapid Access Cardiology (RAC) services are hospital co-located cardiologist-led outpatient clinics providing prompt assessment and management of chest pain. This service model is part of chest pain management in the United Kingdom. However, little data exists on RAC services in Australia. Our aim was to describe the introduction of RAC services to an Australian tertiary centre (utility, safety, and acceptability). METHODS: Referrals were accepted for low intermediate risk chest pain. Referrer and patient clinical data was collected prospectively in the first year of RAC - 4 February 2015 to 4 February 2016. Data was linked to hospital presentations/admissions to identify readmissions/mortality data. RESULTS: Among 520 patients (55.0% male, mean age 55.2 years), 87.6% were referred from emergency and 68.4% assessed within 5 days. The final diagnosis was new coronary artery disease (CAD) in 7.9%, and 81.3% had >=2 cardiovascular risk factors (diabetes, hyperlipidaemia, hypertension, overweight/obesity, smoker, pre-existing CAD, and chronic renal failure). On average, 0.8 cardiac tests were ordered per person. In total, 35 (6.7%) had invasive coronary angiograms, with 51.4% having obstructive CAD. Patients reported in surveys (82.8% response rate) that 93.0% "strongly agreed" RAC services were useful to the community. Referrers were also "very satisfied" with RAC (7/17) or "satisfied" (9/17). Furthermore, of 336 referrals, referrers reported without RAC they would admit the patient in 11.3% of cases. There were 4.8% (25/520) unplanned cardiovascular readmissions and 0.6% (3/520) of these were for acute coronary syndromes and no deaths. CONCLUSIONS: Outpatient RAC services are an accepted, effective and safe pathway for management of low intermediate risk chest pain. PMID- 30278914 TI - Thrombogenic Porcelain Atrium. PMID- 30278915 TI - DEL1 protects against chondrocyte apoptosis through integrin binding. AB - BACKGROUND: Osteoarthritis (OA) is a debilitating disease process, affecting mobility and overall health of millions. Current treatment is for symptomatic relief and discovery of approaches to halt or reverse damage is imperative. Deletion of developmental endothelial locus-1 (Del1) has been shown to increase severity of OA in knockout mice. We examined the intracellular pathways involved in the ability of DEL1 to protect chondrocytes from apoptosis and anoikis and hypothesized that it functioned via integrin signaling. MATERIALS AND METHODS: Primary human chondrocytes were treated with various inducers of apoptosis, including anoikis, in the presence of added DEL1 or bovine serum albumin as control. Various inhibitors of integrin binding were examined for their effect on DEL1 activity. Downstream signaling pathway components were detected by immunoblotting. RESULTS: The addition of DEL1 protected chondrocytes from multiple inducers of apoptosis as measured by cell survival, terminal deoxynucleotidyl transferase dUTP nick end labeling and caspase 3/7 assays (P < 0.05). The effect of DEL1 was blocked by RGD peptides and by antibodies directed to integrin alphaVbeta3, but not by controls or antibody to integrin alpha1 (P < 0.05). Treatment with DEL1 promoted ERK and AKT activation when cells were attached, but only AKT activation under conditions of anoikis. CONCLUSIONS: DEL1 protected chondrocytes from apoptosis in response to activators of either the intrinsic or extrinsic pathways, and to anoikis. This effect was mediated primarily through integrin alphaVbeta3. This represents a therapeutic target for therapies to prevent cartilage degeneration in OA. PMID- 30278916 TI - Lack of disparities in screening for associated anomalies in children with anorectal malformations. AB - INTRODUCTION: Patients with anorectal malformations (ARM) often have associated congenital anomalies and should undergo several screening exams in the first year of life. We hypothesized that racial and socioeconomic disparities exist in the screening processes for these patients. METHODS: After IRB approval, a retrospective review of patients with ARM born between 2005 and 2016 was performed at a quaternary care children's hospital. Demographics including gender, race, insurance, and zip code were collected. Zip code was used as a surrogate for median income. Chart review was performed to identify anomaly type and whether Vertebral defects, Anorectal malformations, Cardiac defects, Tracheo Esophageal fistula, Renal anomalies, and Limb abnormalities screening was performed within 1 y of age. Descriptive statistics and chi square analyses were performed. RESULTS: One hundred patients (59% male, 68% low malformation) were identified. African American and Caucasian subjects represented 41% and 40% of the population, respectively. Overall, 68 of 100 patients had at least one screening test for each of the Vertebral defects, Anorectal malformations, Cardiac defects, Tracheo-Esophageal fistula, Renal anomalies, and Limb abnormalities associations. Although some minor differences were noted (more African Americans received skeletal survey than Caucasians, 80.5% versus 60%, P = 0.00335), no pattern of systematic bias in the receipt or timing of screening was evident based on race, insurance, or income. CONCLUSIONS: There do not appear to be racial or socioeconomic disparities in screening for associated anomalies in patients with ARM. However, overall gaps in screening still exist, and work must be carried out to appropriately screen all patients for associated anomalies. PMID- 30278917 TI - Isolated pancreatic tail remnants after transgastric necrosectomy can be observed. AB - BACKGROUND: Severe necrotizing pancreatitis may result in midbody necrosis and ductal disruption leaving an isolated pancreatic tail. The purpose of this study was to characterize outcomes among patients with an isolated tail remnant who underwent transgastric drainage or necrosectomy (endoscopic or surgical) and determine the need for subsequent operative management. MATERIALS AND METHODS: Patients with necrotizing pancreatitis and retrogastric walled-off collections treated by surgical transgastric necrosectomy or endoscopic cystgastrostomy +/- necrosectomy between 2009 and 2017 were identified by a retrospective chart review. All available preprocedure and postprocedure imaging was reviewed for evidence of isolated distal pancreatic tail remnants. RESULTS: Seventy-four patients were included (40 surgical and 34 endoscopic). All the patients in the surgical group underwent laparoscopic transgastric necrosectomy; the endoscopic group consisted of 26 patients for pseudocyst drainage and eight patients for necrosectomy. A disconnected pancreatic tail was identified in 22 (29%) patients (13 laparoscopic and nine endoscopic). After the creation of the "cystgastrostomy," there were no external fistulas despite the viable tail. Of the 22 patients, four patients developed symptoms at a median of 23 months (two, recurrent episodic pancreatitis; two, intractable pain). Two patients (both initially in endoscopic group) ultimately required distal pancreatectomy and splenectomy at 24 and 6 months after index procedure. CONCLUSIONS: Patients with a walled-off retrogastric collection and an isolated viable tail are effectively managed by a transgastric approach. Despite this seemingly "unstable anatomy," the creation of an internal fistula via surgical or endoscopic "cystgastrostomy" avoids external fistulas/drains and the short-term necessity of surgical distal pancreatectomy. A very small subset requires intervention for late symptoms. PMID- 30278918 TI - IDH1 mutation correlates with a beneficial prognosis and suppresses tumor growth in IHCC. AB - BACKGROUND: Isocitrate dehydrogenase 1/2 (IDH1/2) mutations have been reported in intrahepatic cholangiocarcinoma (IHCC). However, the prognosis of a single IDH1 mutation and impact of mutant IDH1 on IHCC tumor growth remain unclear. METHODS: A total of 85 IHCC tumor samples were sequenced. Prognosis and clinicopathological correlation were analyzed. The role of mutant IDH1 in IHCC tumor growth was measured by cell proliferation assay, colony formation assay in soft agar, and xenograft tumor models. Akt, ERK, p38 MAPK, and JNK signaling, which commonly affect tumor growth, were examined by Western blotting to explore the potential mechanism. RESULTS: IDH1 mutations correlated with a beneficial prognosis and smaller tumor size. Mutant IDH1 exhibited a growth-inhibitory effect on IHCC cell lines in vitro and in vivo. Akt signaling was suppressed in IHCC cell lines expressing a mutant IDH1. The reactivation of Akt signaling by SC79 restored the inhibited growth of cell lines expressing a mutant IDH1 in IHCC. CONCLUSIONS: Collectively, we demonstrated that mutant IDH1 correlates with a beneficial prognosis and inhibits tumor growth by suppressing Akt signaling in IHCC. We suggest that patients with IDH1 mutations could be considered for both less-aggressive therapy and therapy tailored to the presence of their mutant enzyme in the future. PMID- 30278919 TI - Insurance status and pediatric mortality in nonaccidental trauma. AB - BACKGROUND: Nonaccidental trauma (NAT) is a leading cause of injury and death in early childhood. We sought to understand the association between insurance status and mortality in a national sample of pediatric NAT patients. MATERIALS AND METHODS: We performed a retrospective cohort study using the 2012-2014 National Trauma Databank. We included children <=18 y hospitalized with NAT (The International Classification of Diseases, Ninth Revision codes: E967-968). The primary exposure was insurance status (categorized as public, private, and uninsured). The primary outcome was emergency department or inpatient mortality from NAT. RESULTS: We identified 6389 children with NAT. Mean age was 1.6 y (standard deviation 3.7), with 41% female and 42% of an ethnic or racial minority. Most were publicly insured (77%), with 17% privately insured and 6% uninsured. Mean injury severity score (ISS) was 13.9 (standard deviation 10.3). Overall, 516 (8%) patients died following NAT. Compared to patients who survived, those who died were more likely to be younger (mean age 1.0 y versus 1.6 y; P < 0.001), uninsured (13% versus 6%; P < 0.001), transferred to a higher-care facility (57% versus 49%; P < 0.001), and more severely injured (mean ISS 25.9 versus 12.8; P < 0.001). After adjusting for age, race, transfer status, and ISS, uninsured patients had 3.3-fold (95% CI = 2.4-4.6) greater odds of death compared to those with public insurance. For every 1 point increase in ISS, children had 12% (95% CI = 11%-13%) increased adjusted odds of death. CONCLUSIONS: Pediatric patients without insurance had significantly greater odds of death following NAT, compared to children with public insurance. Knowledge that uninsured children comprise an especially vulnerable population is important for targeting potential interventions. PMID- 30278920 TI - Pregnancy after a melanoma diagnosis in women in the United States. AB - BACKGROUND: Melanoma is the third most common cancer in women aged 18-39 years. Medical literature recommends that women wait for at least 2 years before becoming pregnant, yet few studies have examined pregnancy after melanoma. Our aims were to investigate the pregnancy rate after a melanoma diagnosis and the relationship between melanoma treatment and subsequent pregnancy. METHODS: We studied women with a melanoma diagnosis in the Truven Health MarketScan database. Women with a melanoma diagnosis were matched 1:1 to women with no melanoma diagnosis to compare pregnancy rates between groups. For women with melanoma, Cox models were fitted for rates of pregnancy overall, pregnancy if postsurgical treatment was received, and for treatment after pregnancy. RESULTS: The sample included 11,801 women aged 18-40 years with melanoma, who were not pregnant on the index date. These women had a higher rate of pregnancy within 2 years compared to matched controls (15.8% versus 13.6%, P < 0.001). For 0-9 months after diagnosis, women who received postsurgical treatment had a 74% lower probability of becoming pregnant (hazard ratio = 0.26, P = 0.003). Rates of treatment received after pregnancy were not significantly different (hazard ratio = 0.68, P = 0.23). CONCLUSIONS: Our study is the largest review of postmelanoma pregnancy in the United States. After a melanoma diagnosis, women had a slightly higher rate of pregnancy than matched controls, indicating that women are not delaying pregnancy. However, women who received advanced treatment for melanoma had a lower rate of pregnancy than untreated women. Women who became pregnant after a melanoma diagnosis did not have an increased risk of requiring subsequent treatment for melanoma. PMID- 30278921 TI - Large animal models for long-segment tracheal reconstruction: a systematic review. AB - BACKGROUND: The reconstruction of extensive tracheal defects is an unresolved problem. Despite decades of research, a reliable and practical substitute remains to be found. While there have been clinical reports of successful long-segment tracheal reconstruction, reproducibility and widespread applicability of these techniques have yet to be achieved. Large animals such as the dog, pig, sheep, and goat have comparable tracheal morphology and physiology to humans making them useful preclinical models to screen potential therapeutic strategies. MATERIALS AND METHODS: The literature was reviewed to identify large animal models commonly used for tracheal reconstruction. A systematic search of PubMed and EMBASE was performed for large animal studies reporting on the reconstruction of long segment tracheal and carinal defects. Fifty-seven studies were identified for analysis. RESULTS: There is no standard large animal model available for tracheal research. In recent years, livestock species have gained favor over dogs as animal models in this field. The minimum requirements for successful tracheal replacement are rigidity, vascularity, and epithelial lining. Early attempts with synthetic prostheses were met with disappointing results. An autologous tracheal substitute is ideal but hindered by limited donor site availability and the lack of a dominant vascular pedicle for microsurgical reconstruction. Although tracheal allotransplantation enables like-for-like replacement, there are unresolved issues relating to graft vascularity, immunosuppression, and graft preservation. Tissue engineering holds great promise; however, the optimal combination of scaffold, cells, and culture conditions is still indeterminate. CONCLUSIONS: Despite impressive advances in tracheal reconstruction, a durable substitute for extended tracheal defects continues to be elusive. PMID- 30278922 TI - Pleural electrical impedance is a sensitive, real-time indicator of pneumothorax. AB - BACKGROUND: Chest tube management protocols, particularly in patients with alveolar-pleural air leak due to recent surgery or trauma, are limited by concerns over safety, especially concerns about rapid and occult development of pneumothorax. A continuous, real-time monitor of pneumothorax could improve the quality and safety of chest tube management. We developed a rat model of pneumothorax to test a novel approach of measuring electrical impedance within the pleural space as a monitor of lung expansion. MATERIALS AND METHODS: Anesthetized Sprague-Dawley rats underwent right thoracotomy. A novel impedance sensor and a thoracostomy tube were introduced into the right pleural space. Pneumothorax of varying volumes ranging from 0.2 to 20 mL was created by syringe injection of air via the thoracostomy tube. Electrical resistance measurements from the pleural sensor and fluoroscopic images were obtained at baseline and after the creation of pneumothorax and results compared. RESULTS: A statistically significant, dose-dependent increase in electrical resistance was observed with increasing volume of pneumothorax. Resistance measurement allowed for continuous, real-time monitoring of pneumothorax development and the ability to track pneumothorax resolution by aspiration of air via the thoracostomy tube. Pleural resistance measurement demonstrated 100% sensitivity and specificity for all volumes of pneumothorax tested and was significantly more sensitive for pneumothorax detection than fluoroscopy. CONCLUSIONS: The electrical impedance based pleural space sensor described in this study provided sensitive and specific pneumothorax detection, which was superior to radiographic analysis. Real-time, continuous monitoring for pneumothorax has the potential to improve the safety, quality, and efficiency of postoperative chest tube management. PMID- 30278923 TI - Electromagnetic navigational bronchoscopic airway recanalization in patients with vanishing bronchus. AB - BACKGROUND: Stenosis is the most frequent airway complication after lung transplantation. When complete obstruction is diagnosed without possibility of recanalization, options are generally limited to either resection or retransplantation, both associated with increased morbidity and mortality. We describe our experience with a novel technique using electromagnetic navigational bronchoscopy (ENB) to recanalize the occluded airway after lung transplantation. METHODS: Patients who underwent lung transplantation between 2010 and 2016 with subsequent development of complete airway obstruction and failed conventional recanalization attempts were included in this study. All patients underwent attempted recanalization using ENB. Primary outcomes included success of the technique and long-term patency. Secondary outcomes included procedure-related complications. RESULTS: Four patients met inclusion criteria and underwent attempted recanalization using the ENB platform. Location of the obstruction was the bronchus intermedius in two patients, the lingular bronchus in one patient, and the left basilar bronchus in one patient. Mean length of stenosis was 8.8 mm. Three patients (75%) were successfully recanalized and all airways remain patent at 1, 48, and 66 mo. There were no procedure-related complications. The one patient who was unable to be recanalized successfully underwent bilobectomy and died 7 mo later. CONCLUSIONS: ENB is a feasible method of airway recanalization in select patients with bronchial occlusion after lung transplantation. ENB recanalization spares lung parenchyma and avoids risks associated with surgical resection and retransplantation. This novel technique can be added to the armamentarium for thoracic surgeons who diagnose and treat this complicated problem. PMID- 30278924 TI - Outcomes in video-assisted thoracoscopic surgery lobectomies: challenging preconceived notions. AB - BACKGROUND: Most thoracic surgical procedures in the United States are being performed by general surgeons (GSs) without any advanced training. With the recent approval of computed tomography screening for lung malignancy in high-risk populations, the number of thoracic oncologic resections is expected to rise. Previous literature has demonstrated consistently worsened outcomes for patients undergoing thoracic surgical procedure when done by nonthoracic fellowship trained surgeons. Using the American College of Surgeons National Surgical Quality Improvement Project database, we examined short-term outcomes in patients undergoing video-assisted thoracoscopic surgery (VATS) lobectomy for malignancy. MATERIALS AND METHODS: Data were obtained from the American College of Surgeons National Surgical Quality Improvement Project from 2010-2015. We identified patients who had an International Classification of Disease 9 diagnosis of lung cancer (162) who underwent VATS lobectomy (current procedural terminology 32663). We included only adults (>=18y) and elective cases. We excluded patients who had preoperative diagnosis of sepsis, contaminated wound class, or those patients with missing American Society of Anesthesiologists classification, morbid obesity, functional status, length of stay (LOS), or sex, and race information. We identified two groups by specialty: GS versus cardiothoracic (CT) surgeon. We then performed univariate analysis. We then performed propensity score analysis using a 1:3 ratio of general surgery patients to CT patients. Outcomes of interest included 30-d postoperative mortality, 30-d postoperative morbidity, and LOS. RESULTS: A total of 4105 patients were identified, 607 performed by GSs, 3508 performed by CT surgeons. The mean age for patients who underwent lobectomies by GSs was 68.6 versus 67.8 in the CT surgeon group (P < 0.05). The majority were female (58.09% GS versus 57.74% CT surgeon). There was a statistically significant difference in race between groups; patients were more likely to be African American in the CT surgeon group. Operative time was lower in the GS group as opposed to the CT surgeon group 179 min versus 196 (P < 0.01). Univariate analysis (mortality <0.1 CT surgeon and GS) and 1:3 propensity score matched analysis (0.08 GS% versus 0.08% CT surgeon) failed to demonstrate a significant difference in mortality. There was a statistically significant difference in median LOS between groups (6.2 GS versus 5.1 CT surgeon). Univariate and propensity matched analyses of pneumonia, sepsis, wound infection, deep vein thrombosis, transfusion requirement, myocardial infarction stroke, postoperative renal insufficiency, failure to wean, pulmonary embolism, reintubation, and deep organ space infection all failed to demonstrate a statistically significant difference between our groups of interest. Urinary tract infection was noted to be higher in the GS group operating room 2.29 as compared to the CT surgeon group (P value 0.02). CONCLUSIONS: In this large observational study, we found that VATS lobectomies performed by GS compared to the matched CT surgeon cohort had shorter operative time, and there was no difference in major postoperative morbidity or mortality. However, LOS was higher and there was increased risk of urinary tract infection in the GS compared to matched CT surgeon cohort. PMID- 30278925 TI - Free vascularized fascia flap combined with skin grafting for deep toe ulcer in diabetic patients. AB - BACKGROUND: This study introduces a technique for the reconstruction of deep toe defects in diabetic patients using a method that combines free vascularized fascia flap with skin grafting. METHODS: In this retrospective study, conducted between March 2010 and February 2016, 15 diabetic patients with deep toe ulcer received surgeries that combined free vascularized fascia flap with skin grafting, including nine anterolateral thigh fascia lata flaps and six superficial temporal fascia flaps. Their medical records were systematically reviewed from electronic databases. The donor artery was anastomosed to the dorsalis pedis artery in an end-to-side manner, and the vein was anastomosed to the accompanying vein in an end-to-end manner. RESULTS: Thirteen fascia flaps completely survived without any rejection. Partially necrosed grafted skins, which were found in two cases, were healed after routine dressing changes. Patients achieved an esthetic outcome and acceptable functions without further revisions. Two patients suffered from ischemic necrosis of the fascia flap and eventually underwent amputation. CONCLUSIONS: The present study demonstrated that vascularized fascia flap combined with skin grafting has great advantages for correcting deep toe ulcer in diabetic patients characterized by the esthetic outcome, abundant vascularity, surgical simplicity, and good deformability. PMID- 30278926 TI - The impact of location on the prognosis of squamous cell carcinomas of the anorectal region. AB - BACKGROUND: Because anal and rectal squamous cell carcinomas (R-SCCs and A-SCCs) share a common histology and an excellent response to chemoradiation, we hypothesized that R-SCC and A-SCC may represent a similar biological entity, and location would not affect clinical presentation and prognosis. METHODS: Patients diagnosed with R-SCC (n = 2881) and A-SCC (n = 21,854) were identified in the Surveillance, Epidemiology, and End Results database (1998-2013). R-SCCs were staged based on American Joint Committee on Cancer classification for A-SCC, and impact of location was analyzed accordingly. RESULTS: Compared to A-SCC, R-SCCs were more common in females (65% versus 48%, P < 0.001) and older patients (62 versus 56 yrs, P < 0.001). R-SCC presented with more advanced disease than A-SCC: mean size 4.2 versus 3.6 cm; T4 14% versus 5%; nodal involvement 20% versus 15%; and metastases 13% versus 6% (all P < 0.001). In multivariable analysis, R-SCCs and A-SCCs had similar disease-specific survival (DSS) for stages 0, I, and III; however, stage II R-SCC had significantly worse DSS than A-SCCs (P = 0.002). This was due to a greater proportion of T3 (>5 cm) R-SCC tumors (36% versus 27%, P < 0.001), which had a lower DSS than T2 (2-5 cm) tumors. Within T3 and T4 tumors, R SCCs had lower DSS than A-SCCs. CONCLUSIONS: R-SCC presented with higher stages than A-SCC, suggesting a delayed diagnosis. Larger R-SCC (T3-T4) had worse survival compared to T3-4 A-SCC, which may be due to a combination of more advanced disease within-stage as well as the use of less efficacious therapeutic regimens. Therefore, location may represent a significant prognostic factor for SCC of the anorectal region. PMID- 30278927 TI - Minimally invasive surgical exposure among US and Canadian pediatric surgery trainees, 2004-2016. AB - BACKGROUND: Minimally invasive pediatric surgery has increased in breadth and complexity over the past several decades, with little data on minimally invasive surgery (MIS) training in US and Canadian pediatric surgery fellowship programs. METHODS: We performed a time series analysis of Accreditation Council for Graduate Medical Education pediatric surgery fellow case logs from 2003 to 2016. Proportions of cases performed in an MIS fashion as well as per-fellow MIS case averages were recorded over time. RESULTS: There was a 30.9% increase in average number of MIS cases per fellow over the study time period. Twenty-three recorded procedures included MIS and open options (17 abdominal, three thoracic, and three genitourinary). The proportion of cases performed using a minimally invasive approach increased by an average of 29.0%, 14.6%, and 47.0% for each of these categories, respectively. Significant variability was observed in specific cases such as laparoscopic and open inguinal hernias, ranging from 0 to 85 and nine to 152 per trainee, respectively, in the final year of data collection. When examining pyloromyotomy, a high-volume procedure with a known increase in the MIS approach, the proportion of cases performed MIS increased by 83.3%. The minimum and maximum number of cases per fellow recorded ranged from 0 to 114 during the eight years in which MIS pyloromyotomy was recorded. CONCLUSIONS: MIS case exposure among graduating US and Canadian pediatric survey fellows increased substantially during the study period. More granular data, however, are needed to better define the current operative experience and criteria for determination of competency in advanced MIS. PMID- 30278928 TI - Examining length of stay after commonly performed surgical procedures in ACS NSQIP pediatric. AB - BACKGROUND: The objective of this study was to identify ranges of postoperative length of stay (LOS) for common pediatric procedures using a large multi institutional database. MATERIALS AND METHODS: A retrospective analysis of the most frequently performed general surgical procedures in the ACS-NSQIP Pediatric (2013-2015) was performed. These included laparoscopic appendectomy (LA), laparoscopic cholecystectomy, laparoscopic gastrostomy, laparoscopic esophagogastric fundoplication (LF), thoracoscopic repair of pectus excavatum (TPE), open appendectomy (OA), enterostomy closure (OEC), gastrostomy closure (OGC), and bowel resection (OBR). Patients aged <6 mo or >18 y, operations with major concurrent procedures, same-day discharges, operations performed >2 d after admission, and inpatient deaths were excluded. Postoperative LOS was examined for each procedure, including multivariable analysis of risk factors for postoperative LOS > 75th percentile. RESULTS: A total of 29,557 cases were identified and included procedure subgroups ranging from 505 (OBR) to 19,260 (LA) cases. Procedure-specific median postoperative LOS (75th percentile; 90th percentile) were LA 1 d (2 d; 5 d); laparoscopic cholecystectomy 1 d (1 d; 2 d); laparoscopic gastrostomy 2 d (2 d, 4 d); laparoscopic fundoplication 3 d (4 d, 6 d); thoracoscopic repair of pectus excavatum 4 d (5 d, 6 d); OA 3 d (6 d, 9 d); OEC 4 d (6 d, 10 d); OGC 1 d (1 d, 2 d); and OBR 6 d (10 d, 20 d). Preoperative risk factors for high postoperative LOS varied by procedure and included patient demographics, admission factors, case characteristics, and comorbidities. CONCLUSIONS: The range of postoperative LOS and risk factors for high postoperative LOS for commonly performed procedures varied considerably. These results may be a useful reference for benchmarking and resource utilization analyses at the institutional and health systems levels. PMID- 30278929 TI - Rapid growth speed of cysts can predict malignant intraductal mucinous papillary neoplasms. AB - BACKGROUND: Branch duct intraductal papillary mucinous neoplasm (BD-IPMN) has the potential for malignant transformation. Current risk factors used to predict malignant transformation, such as mural nodules and cyst size > 30 mm, are insufficient. Therefore, we aimed to investigate the predictive significance of cyst growth speed. MATERIALS AND METHODS: Between 2006 and 2017, 102 patients underwent pancreatectomy for IPMN. Of these, 50 patients with pathologically diagnosed BD-IPMN were selected for cyst growth analysis. Cyst growth speed, total cyst growth, and cyst growth rate were calculated retrospectively using the maximum diameter of the cyst at the first diagnosis and images taken preoperatively. RESULTS: Of the 50 BD-IPMN cases, 33 were diagnosed as benign (low to intermediate dysplasia) and 17 were malignant (10 high-grade dysplasias and seven invasive carcinomas). While no significant differences were observed in the presence of enhancing mural nodules or cyst size, malignant IPMN grew at a significantly faster speed (5.7 versus 1.6 mm/y; P < 0.001), greater amount of cyst diameter (10.1 versus 3.1 mm; P = 0.015), and greater percentage of cyst diameter (28.5% versus 9.5%; P = 0.006) than those of benign IPMN. Receiver operator characteristic curve analysis indicated that cyst growth speed had the greatest predictive performance among these three factors. Cyst growth speed > 3.5 mm/y was demonstrated to predict malignant IPMN with a sensitivity of 88% and specificity of 91%. CONCLUSIONS: Cyst growth speed > 3.5 mm/y may be a good predictor for malignant IPMN. It can improve the diagnostic accuracy and optimize surgery for BD-IPMN. PMID- 30278930 TI - Functional inclusivity of trauma networks: a pilot study of the North West London Trauma Network. AB - BACKGROUND: Metrics exist to assess and validate trauma system outcomes; however, these are clinically focused and do not evaluate the appropriateness of admission patterns, relative to geography and triage category. We propose the term "functional inclusivity", defined as the number and proportion of triage negative, and/or nonseverely injured patients, who were injured in proximity to a level II/III trauma center but admitted to a level I facility. The aim of this study was to evaluate this metric in the North West London Trauma Network. METHODS: Retrospective, geospatial, observational analysis of registry data from the North West London Trauma Network. We included all adult (>=16 years) patients transported to the level I trauma center at St. Mary's Hospital between 1/1/13 31/12/16. Incident location data were geocoded into longitude/latitude, and drive times were calculated from incident location to each hospital in London's Trauma System, using Google Maps. RESULTS: Of 2051 patients, 907 (44%) were severely injured (injury severity score [ISS] >=15), and 1144 (56%) were nonseverely injured (ISS 1-15). Seven hundred ninety five of the 1144 nonseverely injured patients (69%) were injured in proximity to a level II/III but taken to the level I facility. A total of 488 (24%) patients were triage-negative, and 229 (47%) of these were injured in proximity to a level II/III, but taken to the level I trauma center. CONCLUSIONS: This study has demonstrated the concept of functional inclusivity in characterizing trauma system performance. Further work is required to establish what constitutes an acceptable level of functional inclusivity and what the denominator should be, as well as validating and further evaluating the concept of functional inclusivity. PMID- 30278931 TI - Protective effects of thymoquinone on the healing process of experimental left colonic anastomosis. AB - PURPOSE: Colorectal cancer is globally the third most common cancer. Anastomotic complications remain to be an important issue for colorectal surgery. The aim of this study was to investigate the protective effects of thymoquinone (TQ) on the healing process of left colonic anastomosis in an experimental model. METHODS: Thirty-two male rats were divided into two groups, as the TQ group and the control group. TQ was administered to the TQ group, whereas the control group was given a standard feed and water for 2 wk. Following the creation of a left colonic anastomosis, subjects in both groups were sacrificed on the postoperative (PO) third and seventh days. Anastomotic burst pressures were measured mechanically. Immunohistochemical stainings for proliferating cell nuclear antigen, cluster of differentiation (CD) 31, CD45 were performed, and the matrix metalloproteinase-2 levels were measured. Histologic total scores were calculated according to Ehrlich-Hunt model. A value of P < 0.05 was considered as statistically significant. RESULTS: One rat in the control group that died on the PO fourth day was excluded. Anastomotic burst pressures on the PO seventh day were higher in the TQ group than the control group (P < 0.01). Histopathological total scores on the PO third and seventh days were higher in the TQ group (P < 0.01). In addition, the TQ group revealed lower matrix metalloproteinase-2 scores on the PO third day and higher hydroxyproline levels on the PO seventh day (P < 0.05 and P < 0.01, respectively). CONCLUSIONS: The use of TQ in colorectal surgery cases with left-sided colonic anastomosis resulted with increased anastomotic burst pressures and increased tissue hydroxyproline levels. PMID- 30278933 TI - Hepatorenal protection during renal ischemia by quercetin and remote ischemic perconditioning. AB - BACKGROUND: Pathogenesis of renal ischemia/reperfusion injury (IRI) involves oxidative stress response in the kidney and remote organs. Both quercetin and remote ischemic perconditioning (RIPerC) can protect partially against IRI. This study determined whether combined quercetin and RIPerC could provide an augmented hepatorenal protection against renal IRI. MATERIALS AND METHODS: I/R was induced by clamping renal arteries for 45 min followed by 24-h reperfusion. RIPerC consisted of four cycles of 2 min of left femoral artery ischemia followed by 3 min of reperfusion administered at the beginning of renal ischemia. Rats were divided into five groups: sham, I/R, RIPerC, quercetin (Q + I/R), and combined quercetin and RIPerC (Q + RIPerC). At the end of reperfusion period, blood, urine, and tissue samples were collected. RESULTS: I/R caused kidney dysfunction, as proved by significant decrease in creatinine clearance, and a significant increase in liver functional indicators as evidenced by increased plasma alanine aminotransferase and aspartate aminotransferase activity. This was accompanied by a decrease of glutathione peroxidase and catalase activities with an increase of malondialdehyde levels and histological damages in renal and hepatic tissues. Treatment with RIPerC and quercetin reduced all these changes. However, the measure of improvements was enhanced by combined quercetin and RIPerC treatment. CONCLUSIONS: This study demonstrated protective effects of quercetin and RIPerC strategy on the both kidney and liver after renal I/R. The results suggest that combined quercetin and RIPerC provides an enhanced protection against renal IRI by reduction of lipid peroxidation and augmentation of antioxidant systems. PMID- 30278932 TI - Comparing outcomes with thoracic epidural and intercostal nerve cryoablation after Nuss procedure. AB - BACKGROUND: This study aimed to evaluate postoperative outcomes after minimally invasive repair of pectus excavatum (Nuss procedure) using video-assisted intercostal nerve cryoablation (INC) compared to thoracic epidural (TE). MATERIALS AND METHODS: We performed a single center retrospective review of pediatric patients who underwent Nuss procedure with INC (n = 19) or TE (n = 13) from April 2015 to August 2017. Preoperative, intraoperative, and postoperative characteristics were collected. The primary outcome was length of stay (LOS) and secondary outcomes were intravenous and oral opioid use, pain scores, and complications. Opioids were converted to oral morphine milligram equivalents per kilogram (oral morphine equivalent [OME]/kg). Mann-Whitney U test was used for continuous and chi-squared analysis for categorical variables. RESULTS: There were no significant differences in patient characteristics, except Haller Index (INC: median [interquartile range] 4.3 [3.6-4.9]; TE: 3.2 [2.8-4.0]; P = 0.03). LOS was shorter with INC (INC: 3 [3-4] days; TE: 6 [5-7] days; P < 0.001). Opioid use was higher intraoperatively (INC: 1.08 [0.87-1.37] OME/kg; TE: 0.46 [0.37 0.67] OME/kg; P = 0.002) and unchanged postoperatively (INC: 1.78 [1.26-3.77] OME/kg; TE: 1.82 [1.05-3.37] OME/kg; P = 0.80), and prescription doses were lower at discharge in INC (INC: 30 [30-40] doses; TE: 42 [40-60] doses; P = 0.005). There was no significant difference in postoperative complications (INC: 42.1%; TE: 53.9%; P = 0.51). CONCLUSIONS: INC during Nuss procedure reduced LOS, shifting postoperative opioid use earlier during admission. This may reflect the need for improved early pain control until INC takes effect. Prospective evaluation after INC is needed to characterize long-term pain medication requirements. PMID- 30278934 TI - Risk factors for 30-day readmission after colorectal surgery: does transfer status matter? AB - BACKGROUND: Rates of readmission after colorectal surgery (CRS) range from 9% to 25% and cost the US $300 million annually. The aim of this study was to identify risk factors for 30-d readmission after CRS. Our hypothesis was that transfer from an outside hospital before CRS increases incidence of 30-d readmission. METHODS: Using the Healthcare Cost and Utilization Project Nationwide Readmissions Database, a retrospective analysis of surviving adult patients who underwent inpatient colon and/or rectal resection from 2010 to 2014 was performed. Using multivariable logistic regression, we assessed the direct effect of potential risk factors for readmission, including demographics, hospital characteristics, comorbidities, indication for CRS, and transfer status to the index hospital where the CRS was performed. RESULTS: A total of 336,792 patients were included, and 13% (n = 43,546) were readmitted within 30 d. Overall, 1% of patients (n = 3652) were transferred from another hospital for surgery, and these patients were more likely to be older, have comorbidities, have public insurance, and have low income. After adjustment, age, insurance type, household income, comorbidities, and primary indication for CRS were all significant predictors of readmission. Transfer status did not meaningfully impact the incidence of readmission after accounting for patient and hospital characteristics (aOR 1.08, 95% CI 1.00, 1.18). Patients with primary indications of trauma (aOR 1.88, 95% CI 1.48, 2.38), inflammatory bowel disease (aOR 1.64, 95% CI 1.1.56, 1.71), and ischemia (aOR 1.77, 95% CI 1.1.59, 1.97) were most likely to be readmitted. Patients treated at a rural nonteaching hospital, compared with those at a urban teaching hospital, were significantly less likely to be readmitted (aOR 0.80, 95% CI 0.76, 0.83). CONCLUSIONS: Preoperative factors, such as patient comorbidities and primary indications for CRS, are important risk factors for postoperative readmission. Although transfer status does not independently predict readmission, it serves as a proxy for a high-risk group of patients that could be targeted for future interventions. PMID- 30278935 TI - Magnetic compression technique for colonic anastomosis in rats. AB - BACKGROUND: Magnetic compression technique (MCT) is useful for construction of digestive tract anastomoses in pigs and dogs. This study determined the efficacy of MCT for performing colonic anastomosis in rats. METHODS: Twenty male Sprague Dawley rats (230-280 g) were randomly apportioned to a study group that underwent colonic anastomosis with MCT or a control group subjected to hand-sewn colonic anastomosis. The groups were compared for time to construct the anastomosis, survival rate, and postoperative complications. Animals were euthanized at 1 mo postsurgery to study the burst pressure and histology of the anastomoses. RESULTS: The study group required significantly less time to construct the anastomosis (6.50 +/- 1.58 min) than did the control (15.6 +/- 2.22 min). The survival rate of the study group (100%) was significantly higher than that of the control group (60%). In the control group, three rats developed anastomotic leakage and one rat developed anastomotic obstruction. No anastomotic leakage or obstruction was observed in the study group. The burst pressures of the two groups were similar. Histology showed that the study group had better alignment of the tissue layers and less inflammation compared with the control group. CONCLUSIONS: MCT is a safe and feasible technique for colonic anastomosis in rats, with better postoperative outcomes compared with hand-sewn anastomosis. PMID- 30278936 TI - Does the Surgical Apgar Score predict serious complications after elective major cancer surgery? AB - BACKGROUND: Major cancer surgery is associated with significant risks of perioperative morbidity and mortality, resulting in delayed adjuvant therapy, higher recurrence rates, and worse overall survival. Previous retrospective studies have used the Surgical Apgar Score (SAS) for perioperative risk assessment. This study prospectively evaluated the predictive value of SAS to predict serious complication (SC) after elective major cancer surgery. METHODS: Demographic, comorbidity, procedure, and intraoperative data were collected prospectively for 405 patients undergoing elective major cancer surgery between 2014-17. The SAS was calculated immediately postoperative and outcome data were collected prospectively. Rates of SC according to SAS risk category were compared using Cochran-Armitage trend test. Receiver operating characteristic curves and area under the receiver operating characteristic curves were generated and 95% confidence intervals were calculated. RESULTS: Eighty percent, 17.3%, and 2.7% of patients were low (SAS 7-10), intermediate (SAS 5-6), and high risk (SAS 0-4), respectively, for SC based on their SAS. Forty-six (11.4%) had an SC within 30 days; 3.7% returned to the operating room, 3.7% experienced a urinary tract infection, 3.2% experienced a respiratory complication, 2.7% experienced a wound complication, and 1.2% experienced a cardiac complication. Overall, 9.3%, 18.6%, and 27.3% of patients with SAS 7-10, 5-6, and 0-4 experienced an SC, respectively (P = 0.005). The overall discriminatory ability of the SAS was modest (area under the receiver operating characteristic curves 0.661; 95% confidence intervals, 0.582-0.740). CONCLUSIONS: Although there was an overall association between SAS and higher risk of subsequent postoperative SC in our cohort, the ability of the SAS to accurately predict risk of postoperative SC at the patient level was limited. PMID- 30278937 TI - Perioperative chemotherapy is not associated with improved survival in high-grade truncal sarcoma. AB - BACKGROUND: The treatment benefit of perioperative chemotherapy (CTX) for truncal soft tissue sarcoma (STS) is not well established. This study evaluates the association of CTX with survival for patients with resected primary high-grade truncal STS. MATERIALS AND METHODS: Adult patients with high-grade truncal STS who had curative-intent resection from 2000 to 2016 at seven U.S. institutions were evaluated retrospectively. Patients were stratified by receipt of CTX. Kaplan-Meier curves with log-rank tests were used to compare overall survival (OS) and recurrence-free survival. Logistic regression models were used to evaluate characteristics associated with OS. RESULTS: Of patients with primary high-grade truncal STS, 235 underwent curative-intent resections. The most common histology was undifferentiated pleomorphic sarcoma and mean tumor size was 7.8 cm. Thirty percent of the patients received CTX (n = 70). Among patients receiving CTX, 34% (n = 24) had neoadjuvant CTX, 44% (n = 31) adjuvant CTX, and 21% (n = 15) had neoadjuvant and adjuvant CTX. Patients receiving CTX were more likely to receive radiation (51% versus 34%, P = 0.01), have deep tumors (86% versus 73%, P = 0.037) and solid organ invasion (14% versus 3%, P = 0.001). On univariate analysis, patients who received CTX had worse OS (P < 0.01) and a trend toward worse recurrence-free survival (P = 0.08). Margin status was the only variable associated with improved OS on multivariate analysis (odds ratio 4.36, 95% confidence interval 1.56, 12.13, P < 0.01). CONCLUSIONS: In this multi institutional retrospective analysis of resected high-grade truncal STS, receipt of perioperative CTX was not associated with improved OS, which may be related to selection bias. Microscopically negative margin status was the only independent factor associated with OS. PMID- 30278938 TI - Can imaging studies be omitted in patients with sporadic primary hyperparathyroidism? AB - BACKGROUND: The cost-effectiveness of routine preoperative imaging for patients undergoing parathyroidectomy is controversial. The purpose of this study is to evaluate whether omission of routine preoperative imaging would affect efficiency or safety of parathyroidectomy. METHODS: We implemented a no-imaging protocol for patients with primary hyperparathyroidism and no prior neck surgery. If the patient did not have preoperative parathyroid imaging before evaluation by a surgeon, no radiologic studies were ordered, and the patient was scheduled for parathyroidectomy. We used propensity matching to address differences between the imaging and no-imaging groups. RESULTS: From 2000 to 2015, 83 patients underwent parathyroidectomy without imaging compared to 1245 patients with preoperative imaging. We successfully matched 64 patients with no preoperative imaging to equivalent patients who had imaging prior to surgery. Median age was 60 y, and 84% were women. There was no significant difference in operative time between patients with and without preoperative imaging (84 min for both groups, P < 0.32). Intraoperative parathyroid hormone levels dropped by at least 50% in all patients without preoperative imaging and in 98% of patients with imaging (P < 0.24). Neither group had recurrences 6 mo after surgery. Overall complication rates in the no-imaging (5%) and the imaging group (11%) were also similar (P < 0.18). CONCLUSIONS: Parathyroid surgery without preoperative imaging is safe, effective, and offers equivalent outcomes compared to an approach based on routine preoperative imaging. Experienced surgeons can consider omitting preoperative imaging in patients without a history of neck surgery as this may reduce overall treatment costs. PMID- 30278939 TI - Outcomes of surgical intervention for refractory gastroparesis: a systematic review. AB - BACKGROUND: Gastroparesis (GP) is characterized by delayed gastric emptying with symptoms of nausea, vomiting, early satiety, postprandial fullness, and abdominal pain. Various surgical options exist to treat GP not responding to medical treatments (refractory GP), including gastric electric stimulation (GES), gastrectomy (GTx), and pyloric interventions (PI), whereas the outcomes of these procedures have been published; few comparison studies exist. METHODS: PubMed literature review for articles from September 1988 to October 2017 was performed for prospective and retrospective analyses reporting >5 patients. Unweighted (per study) and weighted (per patient) overall improvement and improvement in symptoms of nausea, vomiting, and abdominal pain were calculated and compared for the different procedures. RESULTS: Of 325 studies satisfying search criteria, 38 met the study criteria and were included for analysis. Total response to intervention, both weighted and unweighted, was greater with PIs compared to GES (P < 0.05). For unweighted symptom improvements, nausea improved more with PI than with GES (P < 0.05). GES improved vomiting more than epigastric pain (P < 0.05). For weighted symptom improvements, pyloric surgery and GTx improved vomiting compared to GES (P < 0.05). CONCLUSIONS: Published outcomes of GES, pyloric surgery, and GTx for refractory GP are compared. Pyloromyotomy/pyloroplasty improves patient response greater than with GES. Weighing by number of studies, pyloric surgery improves nausea and abdominal pain greater than GES. For GES, vomiting is more likely to improve than abdominal pain. Weighing by number of patients, pyloric surgery and GTx improved vomiting compared to GES. PMID- 30278940 TI - Toll-like receptor activation as a biomarker in traumatically injured patients. AB - BACKGROUND: Surgical insult and trauma have been shown to cause dysregulation of the immune and inflammatory responses. Interaction of damage-associated molecular patterns (DAMPs) with toll-like receptors (TLRs) initiates innate immune response and systemic inflammatory responses. Given that surgical patients produce high levels of circulating damage-associated molecular patterns, we hypothesized that plasma-activated TLR activity would be correlated to injury status and could be used to predict pathological conditions involving tissue injury. METHODS: An observational study was performed using samples from a single-institution prospective tissue and data repository from a Level-1 trauma center. In vitro TLR 2, 3, 4, and 9 activation was determined in a TLR reporter assay after isolation of plasma from peripheral blood. We determined correlations between plasma activated TLR activity and clinical course measures of severity. RESULTS: Eighteen patients were enrolled (median Injury Severity Score 15 [interquartile range 10, 23.5]). Trauma resulted in significant elevation in circulation high mobility group box 1 as well as increase of plasma-activated TLR activation (2.8 5.4-fold) compared to healthy controls. There was no correlation between circulating high mobility group box 1 and trauma morbidity; however, the plasma activated TLR activity was correlated with acute physiology and chronic health evaluation II scores (R square = 0.24-0.38, P < 0.05). Patients who received blood products demonstrated significant increases in the levels of plasma activated TLRs 2, 3, 4, and 9 and had a trend toward developing systemic inflammatory response syndrome. CONCLUSIONS: Further studies examining TLR modulation and signaling in surgical patients may assist in predictive risk modeling and reduction in morbidity and mortality. PMID- 30278941 TI - Hepatic topographical changes of endoplasmic reticulum stress and unfolded protein response signaling after hemorrhagic shock and reperfusion. AB - BACKGROUND: Endoplasmic reticulum (ER) stress plays a crucial role in cell death decisions in context of various diseases. Although it is known that ER stress occurs in livers subjected to hemorrhagic shock and reperfusion (HS/R), there is no understanding about the influence of the liver architecture on ER stress and the activation of the unfolded protein response (UPR). MATERIALS AND METHODS: Mice were subjected to a pressure-controlled HS (30 +/- 5 mmHg) for 90 min. Mice were sacrificed 2, 4, 6, 8, 10, 14, 18, and 24 h after shock induction. Plasma levels of inflammatory cytokines (IL-6, CXCL1, CXCL9, CXCL10, CCL2, CCL3) and transaminases were measured. Hematoxylin and eosin stains of paraffin-embedded liver tissue sections were evaluated for liver damage. Immunohistochemistry was used to analyze the hepatic topography of ER stress marker binding immunoglobulin protein and the activation of the three major pathways of the UPR. RESULTS: Compared with sham-operated mice, HS/R led to profound liver damage and an elevation of inflammatory cytokines. We found time-dependent topographical changes of ER stress in the livers. Furthermore, the three major pathways of the UPR represented by protein kinase RNA-like ER kinase, activating transcription factor 6, and inositol-requiring enzyme 1 were activated in differing ways dependent on the zonation within the liver acinus. CONCLUSIONS: These findings show that the liver architecture must be taken into account when investigating the role of ER stress and the UPR in ischemia-reperfusion injury after HS/R. PMID- 30278942 TI - Implant volume estimation in direct-to-implant breast reconstruction after nipple sparing mastectomy. AB - BACKGROUND: Nipple-sparing mastectomy (NSM) is an increasingly popular alternative to more traditional mastectomy approaches. However, estimating the implant volume during direct-to-implant (DTI) reconstruction following NSM is difficult for surgeons with little-to-moderate experience. We aimed to provide a fast, easy to use, and accurate method to aid in the estimation of implant size for DTI reconstruction using the specimen weight and breast volume. METHODS: A retrospective analysis was performed using data from 145 NSM patients with specific implant types. Standard two-dimensional digital mammograms were obtained in 118 of the patients. Breast morphological factors (specimen weight, mammographic breast density and volume, and implant size and type) were recorded. Curve-fitting and linear regression models were used to develop formulas predicting the implant volume, and the prediction performance of the obtained formulas was evaluated using the prospective data set. RESULTS: Two formulas to estimate the implant size were obtained, one using the specimen weight and one using the breast volume. The coefficients of correlation (R2) in these formulas were over 0.98 and the root mean squared errors were approximately 13. CONCLUSIONS: These implant volume estimate formulas benefit surgeons by providing a preoperative implant volume assessment in DTI reconstruction using the breast volume and an intraoperative assessment using the specimen weight. The implant size estimation formulas obtained in the present study may be applied in a majority of patients. PMID- 30278943 TI - Fluorescence imaging-guided robotic thyroidectomy and central lymph node dissection. AB - BACKGROUND: The purpose of this study was to evaluate the feasibility of complete central compartment node dissection (CCND) using fluorescence imaging (FI) during robotic thyroidectomy. METHODS: A total of 110 patients underwent robotic thyroidectomy and CCND from August 2015 to June 2016; 55 patients underwent robotic surgery using FI (FI group) and the other 55 patients without it (control group). The FI group was injected with indocyanine green into the thyroid to enhance the identification of lymph nodes (LNs). RESULTS: Indocyanine green stained LNs were easily detected using FI. The number of harvested LNs was 7.0 in the FI group and 4.8 in the control group (P = 0.004). There was lower rate of transient hypocalcemia in the FI group (18.5%) than control group (26.7%), but there was no significant difference (P = 0.417). There were no other significant differences between the two groups. CONCLUSIONS: The use of FI during robotic thyroidectomy facilitated the identification of LNs and guided complete CCND. PMID- 30278944 TI - Preventive role of superoxide dismutase on radiation-induced periprosthetic capsule development. AB - BACKGROUND: Capsule fibrosis is the most important and annoying complication of breast implant surgery. Radiotherapy (RT) used in the local treatment of breast cancer has an increasing effect on the existing fibrous capsule; this is called radiation-induced fibrosis (RIF). In this randomized controlled experimental study, we aim to investigate the reduction effect of superoxide dismutase (SOD) on RIF. METHODS: Sprague-Dawley rats were randomized into four groups, all of which were subjected to implant surgery. No additional procedures were done for the control group. The other groups were the SOD group, the RT + SOD group, and the RT group. The capsules were evaluated histopathologically. RESULTS: Although SOD reduced surgery-induced capsule formation, it neither prevented nor reduced significantly RIF. CONCLUSIONS: In an experimental model that resembled breast cancer treatment, we concluded that SOD cannot reduce RIF but is effective in reducing capsular fibrosis around the silicone after implant surgery. PMID- 30278945 TI - Mortality after pancreaticoduodenectomy: assessing early and late causes of patient death. AB - BACKGROUND: Safety of pancreaticoduodenectomy has improved significantly in the past 3 decades. Current inpatient and 30-d mortality rates are low. However, incidence and causes of 90-d and 1-y mortality are poorly defined and largely unexplored. METHODS: All patients who had pancreaticoduodenectomy between 2007 and 2016 were included in this single institution, retrospective cohort study. Distributions of pancreaticoduodenectomy-specific morbidity and cause-specific mortality were compared between early (within 90 d) and late (91-365 d) postoperative recovery periods. RESULTS: A total of 551 pancreaticoduodenectomies were performed during the study period. Of these, 6 (1.1%), 20 (3.6%), and 91 (16.5%) patients died within 30, 90, and 365 d after pancreaticoduodenectomy, respectively. Causes of early and late mortality varied significantly (all P <= 0.032). The most common cause of death within 90 d was due to multisystem organ failure from sepsis or aspiration in 9 (45%) patients, followed by post pancreatectomy hemorrhage in 5 (25%) patients, and cardiopulmonary arrest from myocardial infarction or pulmonary embolus in 3 (15%) patients. In contrast, recurrent cancer was the most common cause of death in 46 (65%) patients during the late postoperative period between 91 and 365 d. Mortality from failure to thrive and debility was similar between early and late postoperative periods (15% versus 19.7%, P = 0.76). CONCLUSIONS: Most quality improvement initiatives in patients selected for pancreaticoduodenectomy have focused on reduction of technical complications and improvement of early postoperative mortality. Further reduction in postoperative mortality after pancreaticoduodenectomy can be achieved by improving patient selection, mitigating postoperative malnutrition, and optimizing preoperative cancer staging and management strategies. PMID- 30278946 TI - Postoperative urinary retention after laparoscopic total extraperitoneal inguinal hernia repair. AB - BACKGROUND: Postoperative urinary retention (POUR) after laparoscopic inguinal hernia repair has an incidence of 2%-30%. POUR can lead to increased length of stay, decreased patient satisfaction, and increased health-care costs. The objective of this study was to determine the patient risk factors at our institution contributing to POUR after laparoscopic total extraperitoneal (TEP) inguinal hernia repair. METHODS: A retrospective chart review of patients who underwent a laparoscopic TEP inguinal hernia repair at our institution from 2009 to 2016. POUR is defined as the inability to urinate requiring urinary straight or indwelling catheterization in the postoperative period. Univariate analyses were performed on perioperative variables and their correlation with POUR. RESULTS: In total, 578 laparoscopic TEP inguinal hernia repair patients were included in the study: 277 (48%) indirect, 144 (25%) direct, 6 (1%) femoral, and 151 (26%) combination of direct, indirect, and/or femoral hernias. Of these, 292 (51%) were bilateral, and 286 (49%) were unilateral. Overall, 64 (11.1%) of the 578 patients developed POUR. POUR was significantly associated with benign prostatic hyperplasia, age 60 y or older, urinary tract infection within 30 d, and decreased body mass index. CONCLUSIONS: Patients aged greater than 60 y, with benign prostatic hyperplasia, and a decreased body mass index (<=25.8 kg/m2) were more likely to develop POUR after laparoscopic TEP inguinal hernia repair. In addition, these patients were more likely to develop a urinary tract infection within 30 d. Future quality initiatives can be explored to minimize the incidence of POUR in high-risk patient populations. PMID- 30278947 TI - Autologous fat grafting to lumpectomy defects: complications, imaging, and biopsy rates. AB - BACKGROUND: Autologous fat grafting is emerging as a promising reconstructive technique after breast conservation therapy (BCT). Recent evidence suggests that autologous fat grafting does not increase the risk of cancer recurrence; however, women may still be subject to unnecessary biopsies secondary to suspicious radiologic findings. The purpose of this study was to assess surgical complications and biopsy rates in these patients. METHODS: We retrospectively reviewed the records of women who underwent autologous fat grafting after BCT at a single institution over a 6-y period. Independent variables included demographic and operative details. Outcome variables included complications, and incidence of palpable masses and/or suspicious breast imaging findings requiring biopsy. Descriptive statistics were generated. RESULTS: Between June 2008 and February 2015, 37 women aged 41 to 74 y (mean 54.4 y) underwent a total of 56 fat grafting sessions for correction of contour deformities after BCT. The mean number of fat grafting procedures was 1.5 (range 1-4) per breast. Follow-up ranged from 1 to 99 mo (mean 29.5 mo). Imaging data were available for 31 (83.7%) breasts after autologous fat grafting. Biopsy was recommended in four cases after suspicious imaging findings or palpable masses (10.8%), with benign pathology in all cases. There was one incidence of a local wound infection. No other local or systemic complications were noted. CONCLUSIONS: Our study demonstrated a risk of unnecessary biopsies after autologous fat grafting. Complication rates were low, and it appears to be a safe reconstructive option for the correction of contour deformities after BCT. PMID- 30278948 TI - Upregulation of phosphorylated sphingosine kinase 1 expression in colitis associated cancer. AB - BACKGROUND: Colitis-associated cancer (CAC) is the most serious complication of inflammatory bowel disease. Sphingosine-1-phosphate (S1P) is a bioactive lipid mediator that is generated by sphingosine kinase 1 (SphK1) and is known to play an important role in inflammation and cancer progression. Moreover, SphK1 and S1P act as upstream mediators of proinflammatory cytokine interleukin 6 (IL-6) and signal transducer and activator of transcription-3 (STAT3). We hypothesized that the expression levels of phosphorylated SphK1 (pSphK1), phosphorylated STAT3 (pSTAT3), and IL-6 are universally higher in CAC patients than in sporadic colorectal cancer (CRC) patients because all of these factors are associated with inflammation. In this study, we determined the expression levels of pSphK1 in patients with sporadic CRC and CAC and clarified the importance of S1P in CAC patients. MATERIALS AND METHODS: We randomly selected 10 sporadic CRC patients and 10 CAC patients who underwent curative resection, and we examined their surgical specimens by immunohistochemistry. We determined the expression levels of pSphK1, pSTAT3, and IL-6 in these samples. RESULTS: We found pSphK1 expression to be more prevalent in CAC patients (P = 0.019) and to have a higher immunohistochemistry score (P = 0.005) than in sporadic CRC patients. However, the expression of pSTAT3 and IL-6 did not differ between the patient groups. CONCLUSIONS: To our knowledge, this is the first report comparing pSphK1 expression levels in CAC with those in sporadic CRC. The high levels of pSphK1 expression in CAC suggest an important role of S1P in the disease process of CAC. PMID- 30278949 TI - Mucosal homeostasis is altered in the ileum of gnotobiotic mice. AB - BACKGROUND: The microbiome of the gastrointestinal tract is a vast collection of microorganisms implicated in numerous aspects of normal physiology and disease pathogenesis. The use of gnotobiotic mouse models, with single or specific communities of microbes comprising the microbiome, can enhance our understanding of the microbiome-host relationship. We hypothesized that gnotobiotic mice would exhibit differences in mucosal homeostasis when compared with mice with conventional flora (CF). MATERIALS AND METHODS: Single-organism gnotobiotic mice were generated containing Escherichia coli MG1655, Akkermansia muciniphila, Bacteroides eggerthii, and Clostridium symbiosum, representing four of the major phyla present in the gastrointestinal tract. Distal ileal segments were harvested from adult mice, and histologic sections were H&E stained and used to measure villus height and crypt depth. Immunohistochemistry was performed with Ki67 and TUNEL as markers of proliferation and apoptosis, respectively. RESULTS: When compared to the ileum from CF mice, the ileum from all groups of gnotobiotic mice had significant increases in nearly all measured parameters. In addition, significant differences were seen among certain gnotobiotic groups for villus height, crypt depth, and apoptosis. CONCLUSIONS: Single-organism gnotobiotic mice demonstrate enhanced morphometric parameters compared with mice with CF and show differences in growth patterns among bacterial species. These findings suggest unique interactions between individual bacteria and the host animal which hold potential for future therapeutic strategies aimed at mucosal restoration. The mechanisms involved in this process therefore warrant further study. PMID- 30278950 TI - Prognostic impact of elevated preoperative C-reactive protein on patients with differentiated thyroid carcinoma. AB - BACKGROUND: C-reactive protein (CRP) has been reported to be associated with poorer prognosis in various malignancies. However, the relationship between CRP and differentiated thyroid carcinoma (DTC) remains to be elucidated. METHODS: A total of 45 patients, including 32 patients with preoperative DTC and 13 DTC patients with metastatic disease, were included in the study. The relationships between CRP levels and clinicopathological features were retrospectively analyzed. RESULTS: Analysis using a receiver operating characteristic curve revealed a preoperative CRP cutoff value of 0.155 mg/dL. Patients with preoperative CRP >= 0.155 mg/dL, those with T3 + T4, those with extrathyroidal invasion, or those with stage II, showed a statistically shorter recurrent-free survival than those with preoperative CRP < 0.155 mg/dL, those with T1 + T2, those without extrathyroidal invasion, or those with stage I (P = 0.001, P = 0.004, P = 0.024, and P = 0.025, respectively). Preoperative CRP >= 0.155 mg/dL was an independent prognostic factor for recurrent-free survival in the DTC patients (hazard ratio = 6.334, 95% confidence interval: 1.023-39.234, P = 0.037). The proportion of patients aged >=55 y, and those with T3 + T4, was statistically higher in those with preoperative CRP >= 0.155 mg/dL than in those with preoperative CRP < 0.155 mg/dL (P = 0.037 and P = 0.038, respectively). CONCLUSIONS: Higher preoperative CRP levels have a robust prognostic impact on recurrence-free survival in DTC patients. In addition, higher preoperative CRP levels were associated with age >= 55 y and T3 + T4. PMID- 30278951 TI - Tunneled central venous catheters in pediatric intestinal failure: a single center experience. AB - BACKGROUND: Parenteral nutrition for intestinal failure (IF) often requires a tunneled central venous catheter (CVC). The purpose of this study was to characterize complications after CVC placement and contributors to line loss in pediatric IF patients. METHODS: An institutional review board-approved retrospective review of pediatric (<18 y) IF patients who had a silicone tunneled CVC newly inserted or exchanged from 2012 to 2016 in an IF center was conducted. Patient demographics, procedure service (surgery versus interventional radiology), procedure type (new versus exchange), vessel, and complications related to CVCs were evaluated. Complications included dislodgement, infection, break, occlusion/malfunction, and others. An ethanol-lock protocol for silicone CVCs in IF patients was instituted in January 2012. RESULTS: Twenty-nine IF patients with tunneled CVCs were identified with 182 lines and 18,534 line d. Median age at line insertion was 17.1 mo (interquartile range [IQR] 7.6-31.5) with a median of five catheters (IQR 2-8) per patient. There were 19.2 complications per 1000 line d. Occlusions/malfunctions were the most common complication (6.0/1000 line d) followed by breaks (5.6/1000 line d). Median life of catheters was 51.5 d (IQR 21-129). On regression, adjusting for age, insertion service, and procedure type, shorter line life was associated with younger age (P = 0.04) and placement by interventional radiology (P < 0.01). Dislodgement was associated with newly placed lines relative risk 6.5 (95% CI 2.2-28.8). CONCLUSIONS: CVCs in pediatric IF patients have frequent complications and short line lifetimes. Dislodgement of CVC was an unexpectedly common complication with loss of access in newly placed lines. There may be modifiable processes to mitigate CVC complications. PMID- 30278952 TI - A population-based analysis of outcomes after repair of thoracic aortic emergencies in trauma. AB - BACKGROUND: Large-scale assessments of outcomes in thoracic endovascular repair (TEVAR) for thoracic aortic emergencies are lacking. We evaluated perioperative outcomes of TEVAR compared with open surgery among trauma patients in a large statewide database. MATERIALS AND METHODS: We evaluated the California Office of Statewide Health Planning and Development 2007-2014 patient discharge database. Blunt-injured trauma patients with thoracic aortic emergencies were identified by International Classification for Diseases, Ninth Revision, Clinical Modification diagnosis codes and external cause-of-injury codes. Procedure codes were evaluated for TEVAR or open repair. Outcomes included mortality or complications during the index admission and readmission within 30 d. The association between both operative methods and each outcome was evaluated by two-level logistic regression adjusting for age, length of stay, admission year, trauma-related mortality probability, and comorbidity status. RESULTS: Among over 31 million hospitalizations, we identified 48,357 cases (0.2%) of thoracic aortic disease. Of these, 2159 (4.5%) were unique blunt-injured trauma patients of whom 336 (15.6%) underwent operative repair: 256 TEVAR (76.2%) and 80 (23.8%) open repair. Patients with open repair were older than TEVAR patients (mean age 52.0 versus 46.8, P = 0.038). There were no significant differences in race, sex, injury mechanism, mortality, or 30-d readmission by operative method. However, open repair was associated with greater odds for cardiac, spinal cord, and neurological complications. CONCLUSIONS: Although mortality in trauma patients who underwent TEVAR was similar to that in patients with open repair, TEVAR was associated with fewer complications. This suggests that TEVAR offers clinical benefit over open repair in treating trauma patients with aortic disease. PMID- 30278953 TI - Treatment patterns for ductal carcinoma in situ with close or positive mastectomy margins. AB - BACKGROUND: Mastectomy remains an effective treatment for ductal carcinoma in situ (DCIS) but whether further therapy is warranted for close or positive margins is controversial. We aim to characterize the treatment practices of DCIS throughout the United States in patients who undergo mastectomy with close or positive margins to better understand the use of postmastectomy radiation therapy (PMRT). MATERIALS AND METHODS: Using the 2004-2013 National Cancer Database, we identified all female patients with a diagnosis of DCIS who underwent mastectomy. Distributional characteristics were summarized for overall and margin-stratified samples. Characteristic differences were assessed by region and receipt of radiation. Chi-square and independent sample t-tests were used to assess differences for categorical and continuous variables, respectively. RESULTS: In 21,591 patients who met inclusion criteria, 470 patients with close/positive margins were identified. Sixteen percent of patients with close/positive margins received PMRT compared to 1.5% with negative margins (P < 0.01). There was no difference in PMRT and patient race, insurance status, treatment facility, or endocrine therapy. Patients with close/positive margins who received PMRT were more likely to be in an urban setting from the Midwest (24.6%) and Northeast (21.8%) compared to the West (11.0%) and South (10.7%) (P < 0.01). CONCLUSIONS: Use of PMRT for DCIS following mastectomy with close/positive margins differs across the country. Regional variations in treatment patterns reinforce a need to determine whether PMRT improves survival to establish treatment guidelines. PMID- 30278954 TI - Fetal intervention for congenital chylothorax is associated with improved outcomes in early life. AB - BACKGROUND: Congenital chylothorax (CC) can have devastating consequences for neonates. We sought to determine the outcomes of cases treated at our institution and evaluate the role of fetal intervention. MATERIALS AND METHODS: With Institutional Review Board approval, patients treated at our institution 09/2006 04/2016 with CC were reviewed. History and outcomes were compared between patients undergoing fetal intervention (fetal group) and patients who did not (control group). RESULTS: Twenty-three patients were identified. Mean gestational age at birth was 35 wk. Overall mortality was 30% (7 patients). Nineteen patients (83%) were prenatally diagnosed, and 10 patients (43%) underwent fetal intervention. Birth weight was significantly lower in the fetal group compared to the control group (median interquartile range [IQR]; 2.5 [2.3-3.0] versus 3.3 [2.6-3.7] kg, P = 0.02). Apgar scores were significantly higher in the fetal group than the control group at 1 and 5 min (median [IQR]; 6 [4-8] versus 1 [1 2], P = 0.005 and 8 [7-9] versus 2 [2-6], P = 0.008, respectively). For those patients with prenatal diagnosis of CC and hydrops fetalis, thrombosis and lymphopenia were both improved in the fetal group (thrombosis 0% versus 40%, P = 0.03; lymphocyte nadir [median {IQR}] 1.5 [0.6-2.9] versus 0.1 [0.05-0.2], P = 0.02). Duration of support with mechanical ventilation was significantly shorter in the fetal group (median [IQR]; 1 [0-40] versus 41 [29-75] d, P = 0.04). CONCLUSIONS: Fetal intervention for CC is associated with improved Apgar scores and decreased ventilator days and complications in patients with hydrops fetalis. Fetuses with chylothorax, especially those with hydrops, should be referred to a fetal center for evaluation. PMID- 30278955 TI - Postischemic application of estrogen ameliorates myocardial damage in an in vivo mouse model. AB - BACKGROUND: Cardioprotection provided by estrogen has been recognized for many years. It is noteworthy that most of these studies employ a means of preinjury application in experimental research and the preventive usage in clinical studies. Compared to pretreatment, postischemic administration of estrogen will be more practical in treating myocardial ischemia. On the other hand, defect in circadian clock gene period2 (Per2) has been shown to aggravate ischemia-induced heart damage. Given that Per2 expression decreases as a consequence of menopause, in this study, we aim to determine (1) potential improvement of myocardial function by postischemic administration of 17beta-estradiol (E2) using an in vivo mouse myocardial ischemia/reperfusion (I/R) model and (2) the role of E2 in regulating myocardial Per2 expression following I/R. METHODS: Thirty-minute occlusion of left anterior descending artery followed by 24-h reperfusion was performed on adult C57BL ovariectomized female mice. Groups (n = 3-6/group) were as follows: (1) Sham, (2) I/R + vehicle, and (3) I/R + E2. Vehicle or 0.5 mg/kg of E2 was subcutaneously injected right after 30-min ischemia. Following 24-h reperfusion, myocardial function was determined. Heart tissue was collected for analysis of cleaved caspase-3 and Per2 expression by Western blotting, as well as proinflammatory cytokine production (IL-1beta, IL-6, and TNF-alpha) by enzyme linked immunosorbent assay. RESULTS: I/R significantly impaired left ventricular function and increased myocardial levels of active caspase-3, IL-1beta, and IL-6. Importantly, postischemic treatment of E2 markedly restored I/R-depressed myocardial function, reduced caspase-3 activation, and decreased proinflammatory cytokine production (IL-1beta, IL-6, and TNF-alpha). Intriguingly, a trend of the decreased Per2 level was observed in ovariectomized female hearts subjected to I/R, whereas E2 treatment upregulated myocardial Per2 expression. CONCLUSIONS: Our study represents the initial evidence that postischemic administration of E2 effectively preserves the myocardium against I/R injury and this protective effect of E2 may involve upregulation of Per2 in ischemic heart. PMID- 30278956 TI - Sooner is better: use of a real-time automated bedside dashboard improves sepsis care. AB - BACKGROUND: Minimizing the interval between diagnosis of sepsis and administration of antibiotics improves patient outcomes. We hypothesized that a commercially available bedside clinical surveillance visualization system (BSV) would hasten antibiotic administration and decrease length of stay (LOS) in surgical intensive care unit (SICU) patients. METHODS: A BSV, integrated with the electronic medical record and displayed at bedside, was implemented in our SICU in July 2016. A visual sepsis screen score (SSS) was added in July 2017. All patients admitted to SICU beds with bedside displays equipped with a BSV were analyzed to determine mean SSS, maximum SSS, time from positive SSS to antibiotic administration, SICU LOS, and mortality. RESULTS: During the study period, 232 patients were admitted to beds equipped with the clinical surveillance visualization system. Thirty patients demonstrated positive SSS followed by confirmed sepsis (23 Pre-SSS versus 7 Post-SSS). Mean and maximum SSS were similar. Time from positive SSS to antibiotic administration was decreased in patients with a visual SSS (55.3 +/- 15.5 h versus 16.2 +/- 9.2 h; P < 0.05). ICU and hospital LOS was also decreased (P < 0.01). CONCLUSIONS: Implementation of a visual SSS into a BSV led to a decreased time interval between the positive SSS and administration of antibiotics and was associated with shorter SICU and hospital LOS. Integration of a visual decision support system may help providers adhere to Surviving Sepsis Guidelines. PMID- 30278957 TI - A preoperative prediction model for risk of multiple admissions after colon cancer surgery. AB - BACKGROUND: A subset of patients who undergo colon cancer surgery may be at a high risk of multiple subsequent admissions. We developed a simplified model to predict the preoperative risk of multiple postoperative admissions (MuAdm) among patients undergoing colon resection to aid in preoperative planning. METHODS: Patients aged >=18 y with colon cancer who underwent elective surgical resection identified in discharge claims from California and New York (2008-2011) were included. The primary outcome, MuAdm, was defined as 2 or more admissions in the year following resection. Logistic regression models were developed to identify factors predictive of MuAdm. A weighted point system was developed using beta coefficients (P < 0.05). A random sample of 75% of the data was used for model development, which was validated in the remaining 25% sample. RESULTS: A total of 14,780 patients underwent colon resection for cancer. Almost 30% had an admission in the year after index surgery and 9.8% had MuAdm. The significant predictors of MuAdm were higher Elixhauser comorbidity index score, metastatic disease, payer system, and the number of admissions in the year before surgery. Scores ranged from 0 to 8. Scores <=1 had a 7% risk of MuAdm, and scores >=6 had a >30% risk of MuAdm. CONCLUSIONS: In the year following discharge after resection of colon cancer, nearly 10% of patients are admitted 2 or more times. A simple, preoperative clinical model can prospectively predict the likelihood of multiple admissions in patients anticipating resection. This model can be used for preoperative planning and setting postoperative expectations more accurately. PMID- 30278959 TI - Improved survival in simultaneous lung-liver recipients and candidates in the modern era of lung allocation. AB - BACKGROUND: Liver-lung transplantation (LLT) is a rare procedure performed for patients with end-stage liver and lung disease. The lung allocation score (LAS), introduced in 2005, guides lung allocation including those receiving LLT. However, the impact of the LAS on outcomes in LLT is currently unknown. MATERIALS AND METHODS: The OPTN/United Network for Organ Sharing STAR file was queried for LLT candidates and recipients from 1988 to 2016. Demographic characteristics before (historic) and after (modern) the LAS were compared. Survival was analyzed with the Kaplan-Meier method and log-rank test. RESULTS: In total, 167 candidates were listed for LLT, and 62 underwent LLT. The historic cohort had a higher FEV1% (48.22% versus 29.82%, P = 0.014), higher creatinine (1.22 versus 0.72, P < 0.001), and a higher percentage with pulmonary hypertension as the indication for transplantation (40% versus 0%, P = 0.003) compared with the modern cohort. LLT candidates in the historic cohort had a lower rate of transplant per 100 candidates (10.87 versus 33.33, P < 0.0001) and worse waitlist survival (1 y: 69.6% versus 80.9%, 3 y: 39.1% versus 66.8%, P = 0.004). Post-transplant survival was significantly lower in the historic cohort (1 y: 50.0% versus 82.7%, 5 y: 40.0% versus 69.0%, 10 y: 20.0% versus 55.5%, P = 0.0099). CONCLUSIONS: Most analyses of LLT have included patients before and after the introduction of the LAS. Our study shows that LLT candidates and recipients before the modern allocation system had distinct baseline characteristics and worse overall survival. Although many factors contributed to recent improved outcomes, these cohorts are significantly different and should be treated as such in future studies. PMID- 30278958 TI - Are we overtreating intraductal papillomas? AB - BACKGROUND: The management of intraductal papillomas (IDPs) diagnosed on core needle biopsy (CNB) remains controversial regarding whether excision is required. We evaluated whether excision of IDPs might be overtreatment based on a consecutive patient population where all IDPs were routinely excised. MATERIALS AND METHODS: We retrospectively reviewed the records of consecutive patients treated with excision of IDPs at our institution from 2009 to 2016. We evaluated the rate of upgrade of IDPs on CNB and factors predicting for malignant upgrade. RESULTS: Of 153 CNB specimens, 136 (88.9%) were IDPs without atypia and 14 (9.2%) showed atypia. The overall upgrade rate on final pathology was 7.3% with 1.3% for invasive cancer, 2.7% for ductal carcinoma in situ, and 3.3% for atypical ductal hyperplasia. Of the 14 patients with atypia on CNB, two of these patients (14.2%) were found to have ductal carcinoma in situ. In the absence of atypia on CNB, upgrade rates were 1.5% for invasive and 1.5% for in situ carcinoma. Personal history of breast cancer and magnetic resonance imaging-guided biopsy predicted for malignant upgrade. CONCLUSIONS: IDPs on CNB have a low chance of harboring an occult malignancy. Given the low probability of upgrade to invasive breast cancer, it is reasonable to consider watchful surveillance in the absence of a prior personal history of breast cancer or atypia on CNB. PMID- 30278960 TI - Gamma-glutamyl transpeptidase to platelet ratio predicts short-term outcomes in hepatocellular carcinoma patients undergoing minor liver resection. AB - BACKGROUND: There is a strong correlation between liver fibrosis and postoperative morbidity after hepatectomy in hepatocellular carcinoma (HCC) patients. The aim of this study was to evaluate which noninvasive fibrosis index (gamma-glutamyl transpeptidase to platelet ratio [GPR], aspartate aminotransferase to platelet ratio index, fibrosis-4 index, or Forns index) was best able to predict complications in patients undergoing hepatectomy for HCC. MATERIALS AND METHODS: This retrospective analysis included 275 patients who underwent hepatectomy for HCC from January 2008 to December 2012. Postoperative mortality was defined as death within 90 d after surgery. Complications were grouped into seven grades on the basis of the modified Clavien classification, and major postoperative complications were defined as grade 3 or above. The influence of noninvasive fibrosis indices on postoperative outcomes was assessed by receiver operating characteristic analysis. The primary outcomes were overall complications and major complications, estimated by univariate and multivariate analysis. RESULTS: Patients with HCC undergoing anatomical liver resection in the authors' department were evaluated for this study. Finally, 275 patients who underwent minor liver resection (<=2 liver segments) were included. Of these, 231 (84%) were male. The multivariate analysis indicated that the GPR index was not only independently associated with overall complications (hazard ratio, 2.692; 95% confidence interval [CI], 1.626-4.250; P < 0.001) but also independently predictive of major complications (hazard ratio, 1.143; 95% CI, 1.046-1.249; P = 0.03). The areas under the receiver operating characteristic curve for predicting overall complications and major complications for the GPR index were 0.704 (95% CI, 0.643-0.765; P < 0.001) and 0.752 (95% CI, 0.638-0.865; P < 0.001), respectively. CONCLUSIONS: The data suggested that the GPR index could be a promising predictor of overall postoperative complications and major complications after minor hepatectomy for HCC. PMID- 30278961 TI - Fetal lung transcriptome patterns in an ex vivo compression model of diaphragmatic hernia. AB - BACKGROUND: The purpose of this study was to employ a novel ex vivo lung model of congenital diaphragmatic hernia (CDH) to determine how a mechanical compression affects early pulmonary development. METHODS: Day-15 whole fetal rat lungs (n = 6 12/group) from nitrofen-exposed and normal (vehicle only) dams were explanted and cultured ex vivo in compression microdevices (0.2 or 0.4 kPa) for 16 h to mimic physiologic compression forces that occur in CDH in vivo. Lungs were evaluated with significance set at P < 0.05. RESULTS: Nitrofen-exposed lungs were hypoplastic and expressed lower levels of surfactant protein C at baseline. Although compression alone did not alter the alpha-smooth muscle actin (ACTA2) expression in normal lungs, nitrofen-exposed lungs had significantly increased ACTA2 transcripts (0.2 kPa: 2.04 +/- 0.15; 0.4 kPa: 2.22 +/- 0.11; both P < 0.001). Nitrofen-exposed lungs also showed further reductions in surfactant protein C expression at 0.2 and 0.4 kPa (0.53 +/- 0.04, P < 0.01; 0.69 +/- 0.23, P < 0.001; respectively). Whereas normal lungs exposed to 0.2 and 0.4 kPa showed significant increases in periostin (POSTN), a mechanical stress-response molecule (1.79 +/- 0.10 and 2.12 +/- 0.39, respectively; both P < 0.001), nitrofen-exposed lungs had a significant decrease in POSTN expression (0.4 kPa: 0.67 +/- 0.15, P < 0.001), which was confirmed by immunohistochemistry. CONCLUSIONS: Collectively, these pilot data in a model of CDH lung hypoplasia suggest a primary aberration in response to mechanical stress within the nitrofen lung, characterized by an upregulation of ACTA2 and a downregulation in SPFTC and POSTN. This ex vivo compression system may serve as a novel research platform to better understand the mechanobiology and complex regulation of matricellular dynamics during CDH fetal lung development. PMID- 30278962 TI - National trends in volume-outcome relationships for extracorporeal membrane oxygenation. AB - BACKGROUND: The use of extracorporeal membrane oxygenation (ECMO) has emerged as a common therapy for severe cardiopulmonary dysfunction. We aimed to describe the relationship of institutional volume with patient outcomes and examine transfer status to tertiary ECMO centers. MATERIALS AND METHODS: Using the National Inpatient Sample, we identified adult patients who received ECMO from 2008 to 2014. Individual hospital volume was calculated as tertiles of total institutional discharges for each year independently. RESULTS: Of the total 18,684 adult patients placed on ECMO, 2548 (13.6%), 5278 (28.2%), and 10,858 (58.1%) patients were admitted to low-, medium-, and high-volume centers, respectively. Unadjusted mortality at low-volume hospitals was less than that of medium- (43.7% versus 50.3%, P = 0.03) and high-volume hospitals (43.7% versus 55.6%, P < 0.001). Length of stay and cost were reduced at low-volume hospitals compared to both medium- and large-volume institutions (all P < 0.001). In high volume institutions, transferred patients had greater postpropensity-matched mortality (58.5% versus 53.7%, P = 0.05) and cost ($190,299 versus $168,970, P = 0.009) compared to direct admissions. On exclusion of transferred patients from propensity analysis, mortality remained greater in high-volume compared to low volume centers (50.2% versus 42.8%, P = 0.04). Predictors of mortality included treatment at high-volume centers, respiratory failure, and cardiogenic shock (all P < 0.001). CONCLUSIONS: Our findings show increased in-hospital mortality in high-volume institutions and in patients transferred to tertiary centers. Whether this phenomenon represents selection bias or transfer from another facility deserves further investigation and will aid with the identification of surrogate markers for quality of high-risk interventions. PMID- 30278963 TI - Do we CARE about the quality of case reports? A systematic assessment. AB - BACKGROUND: Clinical case reports are important sources of information on the identification and treatment of new or rare diseases. The CAse REport (CARE) Statement and Checklist represents consensus-based guidelines for clinical case reports. How well case reports adhere to these guidelines is unknown. MATERIAL AND METHODS: A systematic PubMed and OVID search was used to identify case reports on isolated splenic metastasis from 2007 to 2017 in English language journals. MeSH search terms included "(isolated splenic metastasis OR solitary splenic metastasis) AND case report." We retrieved 79 articles and 55 directly addressed the topic of interest. Each was scored dichotomously using the 13 categories with 36 item descriptors on the CARE checklist. RESULTS: Of the 55 case reports, none fully followed the CARE guidelines; only 56.4% met 23 descriptors and none had more than 29 of 36 descriptors. Patient symptoms were not described in 40.0%, and in 47.3%, the abstract did not identify the main outcomes. All reports included patient's age and diagnostic methods. Most case reports reported the type of intervention (96.4%) and effect of the intervention (96.4%). None included patient-assessed outcomes or the patient's perspective. Only 49.1% included strengths and limitations of patient management, stating that the most effective treatment is unknown. CONCLUSIONS: None of the case reports on isolated splenic metastasis completely followed the CARE guidelines. Most reports did cover diagnostic workup and therapeutic interventions and gave a summary of the literature. Higher quality case reports would be useful in facilitating recognition of rare disease processes and informing clinical practice. PMID- 30278964 TI - Underuse of exon mutational analysis for gastrointestinal stromal tumors. AB - BACKGROUND: Tyrosine kinase inhibitors (TKI) have become the guideline recommended therapy for high-risk resected and advanced gastrointestinal stromal tumors (GISTs). Exon mutational analysis (EMA) is used to inform pretherapy response to TKI and may predict overall prognosis. Despite these benefits, EMA remains underused, and its impact on TKI therapy decision-making remains unexplored. MATERIALS AND METHODS: A retrospective cohort was established from 104 patients receiving treatment for GISTs from 2006 to 2017. Current National Comprehensive Cancer Network guidelines indicate that EMA should be considered for all patients undergoing TKI therapy to identify genotypes that are likely, or unlikely, to respond to treatment. We first tracked guideline-considered EMA use and subsequent impact on treatment decision-making. A questionnaire was then administered to gastrointestinal medical oncologists to assess EMA perception. RESULTS: Among 104 GIST patients, 54 (52%) received TKI therapy. Of these, only 22 (41%) received EMA. Informed by EMA, treatment decisions included 59% who continued with original TKI therapy, 32% who switched to an alternative TKI, and 9% who discontinued or received no TKI. Although 92% of physicians indicated EMA was a valuable tool, only 62% indicated they used it "frequently" or "always" to inform treatment decisions. CONCLUSIONS: Less than half of patients receiving TKI therapy for GISTs received EMA at a comprehensive cancer center. Despite this low uptake, when it was performed, EMA guided alternative treatment decision in 41% of patients. Physician survey responses indicated that interventions targeting physician education and an electronic medical record reminder may improve EMA uptake. PMID- 30278965 TI - Extended neuromuscular blockade in acute respiratory distress syndrome does not increase mortality. AB - BACKGROUND: Neuromuscular blockade (NMB) is often utilized in the treatment of acute respiratory distress syndrome (ARDS). Its use for a period of 48 h has been shown to improve mortality in randomized control trials. We aimed to characterize outcomes associated with a prolonged NMB. We hypothesized that the duration of NMB would not be associated with increased mortality. MATERIALS AND METHODS: This was a retrospective review from June 2014 to October 2016 of patients admitted to the surgical intensive care unit and receiving cisatracurium for ARDS. Patients paralyzed for <= 48 h (SHORT) were compared to those paralyzed for longer durations (LONG). Primary outcome was mortality. Parametric and nonparametric tests were utilized for the purposes of the comparison. A multivariate logistic regression model was utilized to adjust for differences. RESULTS: Of 73 patients meeting inclusion criteria, 32 (44%) were SHORT and 41 (56%) LONG. Compared to the LONG cohort, those in SHORT were older (60 versus 52 years, P = 0.04) but were comparable with respect to sex, acute physiology and chronic health evaluation IV scores, presence of concurrent pneumonia, and the use of vasopressors. SHORT patients were less likely to require rescue therapy with inhaled nitric oxide (28% versus 66%, P < 0.01). Overall mortality was 60%. There was no difference in the adjusted odds for mortality (adjusted odds ratio: 0.57, P = 0.33). Secondary outcomes including deep venous thrombosis and pneumonia did not differ between the two groups. CONCLUSIONS: Extended NMB for ARDS was not associated with increased mortality. Discontinuation of this modality should not be based solely on the duration of therapy. PMID- 30278966 TI - Cost-effectiveness of surgeon performed intraoperative specimen ink in breast conservation surgery. AB - BACKGROUND: Re-excision rates after breast conservation surgery are reported to be 20%-40%. Inaccuracies with specimen orientation may affect margin assessment. This study examined whether the addition of surgeon performed intraoperative inking of the lumpectomy specimen after adoption of margin guidelines would be cost-effective. METHODS: A retrospective review of a prospective surgical database was performed from 2009 to 2017. Patients with initial lumpectomy and a preoperative diagnosis of invasive breast carcinoma or ductal carcinoma in situ (DCIS) were included. Re-excision rates and the surgical costs per 100 initial lumpectomies were compared across three periods: before margin guideline publication, after guideline adoption, and after the addition of intraoperative surgeon performed specimen inking. RESULTS: Four hundred initial lumpectomies were evaluated. Overall re-excision rate was 21% (n = 84). There was a nonsignificant reduction in re-excision rates after margin guidelines from 24% (n = 36) to 20% (n = 23) and to 19% (n = 25) after addition of intraoperative specimen ink. Re-excision rates were significantly lower for invasive cancer than for DCIS across three periods (20%, 15%, and 12% versus 37%, 33%, and 31%) (odds ratio 3.31, P = 0.007). The estimated cost of re-excision per 100 initial lumpectomies decreased after guidelines by 25% ($128,270) for invasive breast cancer and by 11% ($102,616) for DCIS. The addition of intraoperative specimen inking after margin guideline adoption resulted in further 17% cost savings ($66,692) for invasive breast cancer and 5% ($41,308) for DCIS. CONCLUSIONS: Surgeon performed intraoperative inking of the lumpectomy specimen after adoption of margin guidelines is a cost-effective technique in breast conservation surgery. PMID- 30278967 TI - MC1R gene polymorphisms are associated with dysfunctional immune responses and wound infection after burn injury. AB - BACKGROUND: Systemic inflammatory response syndrome (SIRS) is associated with organ failure and infectious complications after major burn injury. Recent evidence has linked melanocortin signaling to anti-inflammatory and wound-repair functions, with mutations in the melanocortin 1 receptor (MC1R) gene leading to increased inflammatory responses. Our group has previously demonstrated that MC1R gene polymorphisms are associated with postburn hypertrophic scarring. Thus, we hypothesized that MC1R single nucleotide polymorphisms (SNPs) would be associated with increased burn-induced SIRS and increased infectious complications. METHODS: We performed a retrospective cohort study of adults (>18 y of age) admitted to our burn center with >20% total body surface area (TBSA) partial/full thickness burns between 2006 and 2013. We screened for five MC1R SNPs (V60L, V92M, R151C, R163Q, T314T) by polymerase chain reaction from genomic DNA isolated from blood samples. We performed a detailed review of each patient chart to identify age, sex, race, ethnicity, %TBSA burned, burn wound infections (BWIs), and 72-hr intravenous fluid volume, the latter a surrogate for a dysfunctional inflammatory response to injury. Association testing was based on multivariable regression. RESULTS: Of 106 subjects enrolled, 82 had complete data for analysis. Of these, 64 (78%) were male, with a median age of 39 and median burn size of 30% TBSA. A total of 36 (44%) subjects developed BWIs. The median total administered IV crystalloid in first 72h was 24.6 L. In multivariate analysis, the R151C variant allele was a significant independent risk factor for BWI (adjusted prevalence ratio 2.03; 95% CI: 1.21-3.39; P = 0.007), and the V60L variant allele was independently associated with increased resuscitation fluid volume (P = 0.021). CONCLUSIONS: This is the first study to demonstrate a significant association between genetic polymorphisms and a nonfatal burn-induced SIRS complication. Our findings suggest that MC1R polymorphisms contribute to dysfunctional responses to burn injury that may predict infectious and inflammatory complications. PMID- 30278968 TI - Do surgeons and patients/parents value shared decision-making in pediatric surgery? A systematic review. AB - BACKGROUND: Shared decision-making (SDM) is touted as the preferred approach to clinical counseling. However, few data exist regarding whether patients prefer SDM over surgeon-guided discussions for complex surgical decision-making. Even fewer data exist regarding surgeon preferences. Such issues may be especially pronounced in pediatric surgery given the complex decision-making triad between patients/parents and surgeons. The objective of this systematic review was to evaluate patient/parent and surgeon attitudes toward SDM in pediatric surgery. METHODS: A systematic review of English language articles in Medline, EMBASE, and Cochrane databases was performed. Inclusion and exclusion criteria were predefined. Text screening and data abstraction were performed by two investigators. RESULTS: Seven thousand five hundred eighty-four articles were screened. Title/abstract review excluded 7544 articles, and full-text review excluded four articles. Thirty-six articles were identified as addressing patient/parent or surgeon preferences toward SDM in pediatric surgery. Subspecialties included Otolaryngology (33%), General Surgery (30%), Plastics (14%), Cardiac (11%), Urology (8%), Neurosurgery (6%), Orthopedics (6%), and Gynecology (3%). Most studies (94%) evaluated elective/nonurgent procedures. The majority (97%) concentrated on patient/parent preferences, whereas only 22% addressed surgeon preferences. Eleven percent of studies found that surgeons favored SDM, and 73% demonstrated that patients/parents favored SDM. CONCLUSIONS: Despite recommendations that SDM is the preferred approach to clinical counseling, our systematic literature review shows that few studies evaluate patient/parent and surgeon attitudes toward SDM in pediatric surgery. Of these studies, very few focus on complex, urgent/emergent decision-making. Further research is needed to understand whether patients/parents, as well as surgeons, may prefer a more surgeon-guided approach to decision-making, especially when surgery is complex or taking place in urgent/emergent settings. PMID- 30278970 TI - Failure to rescue and disparities in emergency general surgery. AB - BACKGROUND: Racial and socioeconomic disparities are well documented in emergency general surgery (EGS) and have been highlighted as a national priority for surgical research. The aim of this study was to identify whether disparities in the EGS setting are more likely to be caused by major adverse events (MAEs) (e.g., venous thromboembolism) or failure to respond appropriately to such events. METHODS: A retrospective cohort study was undertaken using administrative data. EGS cases were defined using International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic codes recommended by the American Association for the Surgery of Trauma. The data source was the National Inpatient Sample 2012-2013, which captured a 20%-stratified sample of discharges from all hospitals participating in the Healthcare Cost and Utilization Project. The outcomes were MAEs, in-hospital mortality, and failure to rescue (FTR). RESULTS: There were 1,345,199 individual patient records available within the National Inpatient Sample. There were 201,574 admissions (15.0%) complicated by an MAE, and 12,006 of these (6.0%) resulted in death. The FTR rate was therefore 6.0%. Uninsured patients had significantly higher odds of MAEs (adjusted odds ratio, 1.16; 95% confidence interval, 1.13-1.19), mortality (1.28, 1.16-1.41), and FTR (1.20, 1.06-1.36) than those with private insurance. Although black patients had significantly higher odds of MAEs (adjusted odds ratio, 1.14; 95% confidence interval, 1.13-1.16), they had lower mortality (0.95, 0.90-0.99) and FTR (0.86, 0.80-0.91) than white patients. CONCLUSIONS: Uninsured EGS patients are at increased risk of MAEs but also the failure of health care providers to respond effectively when such events occur. This suggests that MAEs and FTR are both potential targets for mitigating socioeconomic disparities in the setting of EGS. PMID- 30278969 TI - Microfluidics contrasted to thrombelastography: perplexities in defining hypercoagulability. AB - BACKGROUND: Elevated clot strength (maximum amplitude [MA]) measured by thrombelastography (TEG) is associated with thrombotic complications. However, it remains unclear how MA translates to thrombotic risks, as this measurement is independent of time, blood flow, and clot degradation. We hypothesize that under flow conditions, increased clot strength correlates to time-dependent measurements of coagulation and resistance to fibrinolysis. MATERIALS AND METHODS: Surgical patients at high risk of thrombotic complications were analyzed with TEG and total thrombus-formation analysis system (T-TAS). TEG hypercoagulability was defined as an r <10.2 min, angle >59, MA >66 or LY30 <0.2% (based off of healthy control data, n = 141). The T-TAS AR and PL chips were used to measure clotting at arterial shear rates. T-TAS measurements include occlusion start time, occlusion time (OT), occlusion speed (OSp), and total clot generation (area under the curve). These measurements were correlated to TEG indices (R time, angle, MA, and LY30). Both T-TAS and TEG assays were challenged with tissue plasminogen activator (t-PA) to assess clot resistance to fibrinolysis. RESULTS: Thirty subjects were analyzed, including five controls. TEG-defined hypercoagulability by MA was detected in 52% of the inflammatory bowel disease/cancer patients; 0% was detected in the controls. There were no TEG measurements that significantly correlated with T-TAS AR and PL chip. However, in the presence of t-PA, T-TAS AR determined OSp to have an inverse relationship with TEG angle (-0.477, P = 0.012) and LY30 (-0.449, P = 0.019), and a positive correlation with R time (0.441 P = 0.021). In hypercoagulability determined by TEG MA, T-TAS PL had a significantly reduced OT (4:07 versus 6:27 min, P = 0.043). In hypercoagulability defined by TEG LY30, T-TAS PL had discordant findings, with a significantly prolonged OT (6:36 versus 4:30 min, P = 0.044) and a slower OSp (10.5 versus 19.0 kPa/min, P = 0.030). CONCLUSIONS: Microfluidic coagulation assessment with T-TAS has an overall poor correlation with most TEG measurements in a predominantly hypercoagulable patient population, except in the presence of t-PA. The one anticipated finding was an elevated MA having a shorter time to platelet-mediated microfluidic occlusion, supporting the role of platelets and hypercoagulability. However, hypercoagulability defined by LY30 had opposing results in which a low LY30 was associated with a longer PL time to occlusion and slower OSp. These discordant findings warrant ongoing investigation into the relationship between clot strength and fibrinolysis under different flow conditions. PMID- 30278971 TI - Frequency and timing of short-term complications following abdominoperineal resection. AB - BACKGROUND: Abdominoperineal resection (APR) is primarily used for rectal cancer and is associated with a high rate of complications. Though the majority of APRs are performed as open procedures, laparoscopic APRs have become more popular. The differences in short-term complications between open and laparoscopic APR are poorly characterized. METHODS: We conducted a retrospective cohort study using the American College of Surgeons National Surgical Quality Improvement Program database to determine the frequency and timing of onset of 30-d postoperative complications after APR and identify differences between open and laparoscopic APR. RESULTS: A total of 7681 patients undergoing laparoscopic or open APR between 2011 and 2015 were identified. The total complication rate for APR was high (45.4%). APRs were commonly complicated by blood transfusion (20.1%), surgical site infection (19.3%), and readmission (12.3%). Laparoscopic APR was associated with a 14% lower total complication rate compared to open APR (36.0% versus 50.1%, P < 0.001). This was primarily driven by a decreased rate of transfusion (10.7% versus 24.9%, P < 0.001) and surgical site infection (15.5% versus 21.2%, P < 0.001). Laparoscopic APR had shorter length of stay and decreased reoperation rate but similar rates of readmission and death. Cardiopulmonary complications occurred earlier in the postoperative period after APR, whereas infectious complications occurred later. CONCLUSIONS: Short-term complications following APR are common and occur more frequently in patients who undergo open APR. This, along with factors such as risk of positive pathologic margins, surgeon skill set, and patient characteristics, should contribute to the decision-making process when planning rectal cancer surgery. PMID- 30278972 TI - Intraoperative fluid restriction in hyperthermic intraperitoneal chemotherapy. AB - BACKGROUND: Multiple studies highlight the importance of liberal fluid administration in cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC). Over-resuscitation can delay recovery and wound healing. We report an intraoperative protocol that restricts fluid administration and minimizes morbidity. MATERIALS AND METHODS: Retrospective analysis of 35 patients that underwent CRS-HIPEC for curative intent under fluid restriction protocol from June 2015 to July 2017 was performed. Protocol consists of continuous infusion of vasopressin 0.02 units/h and maintaining urine output at 0.5 mL/kg/h via crystalloid and colloid. Endpoint was Clavien-Dindo >=3 events within 30 d of CRS-HIPEC. RESULTS: Median age was 56 y; 71% were female. Malignancies treated: appendix (49%), colon (31%), and other (20%). Median peritoneal cancer index was 15, complete cytoreduction was achieved in 91% of patients. Median time for return of bowel function was 5 d, median length of hospital stay was 7 d. There were 28 bowel anastomoses. Median intraoperative crystalloid, colloid, and packed red blood cells were (1900, 1500, and 700 mL), respectively. Clavien-Dindo grade 3-4 events occurred in five patients. There were no deaths 30 d after surgery. CONCLUSIONS: A fluid restriction protocol appears to be safe and feasible in the setting of CRS-HIPEC for curative intent. PMID- 30278973 TI - Inhibition of autophagy after perforator flap surgery increases flap survival and angiogenesis. AB - BACKGROUND: The survival ratio of multiterritory perforator flap is variable. Therefore, surviving mechanisms are increasingly explored to identify novel therapeutics. The condition of the choke zone is essential for perforator flap survival. In this study, we investigated autophagy in the choke zone after flap surgery. MATERIALS AND METHODS: The flap model involved a perforator flap with three territories that was located on the right dorsal side of a rat. A total of 36 rats were divided into six groups, including the control, 0 d postoperative (PO), 1, 3, 5, and 7 d PO groups. In addition, 72 rats were divided into three groups, including a control group, a 3-methyladenine (3-MA) group, and a rapamycin group. Skin tissue of rats was used for measuring autophagy proteins, vascular endothelial growth factor (VEGF) expression, and histological examination. On day 7 after surgery, the survival ratio of each flap was determined. RESULTS: The expression of autophagy and VEGF in the second choke zone (choke II) was increased after flap surgery. Among the three groups, the survival ratio of flaps in the 3-MA group was the highest. Furthermore, the angiogenesis level in the 3-MA group in choke II was the highest among the three groups. CONCLUSIONS: Autophagy was initiated by surgery in choke II, and VEGF expression in choke II was increased after flap surgery. Inhibiting autophagy after perforator flap surgery is beneficial for flap survival and for promoting angiogenesis in choke II.

AB - BACKGROUND: There is a very small chance of success for nerve reconstruction in patients with old total brachial plexus palsy who visit after 2 y or suffer from flail upper extremity after the failure of previous operations. MATERIALS AND METHODS: For these individuals, the surgeon has to find a recipient motor nerve to perform free gracilis muscle transplantation. In this study, contralateral medial pectoral nerve from the intact side was transferred to the damaged side as a recipient nerve. Then, in the second operation, approximately 15 mo later, the free gracilis muscle transfer was performed. The gracilis muscle was removed and transferred to provide elbow and finger flexion. RESULTS: In a retrospective study (over 10 y), we reviewed 68 patients for whom this method had been performed. After 1 y, the results were investigated using the Medical Research Council grading system. Five patients did not participate in the study, and the muscle underwent necrosis in two patients. M3 and M4 muscle power was regained in 26 (42.6%) and 21 (34.4%) patients, respectively. CONCLUSIONS: Contralateral pectoral nerve transfer followed by free muscle transplantation can be a good option for patients with old total brachial plexus palsy. PMID- 30278975 TI - Long-term consequences of abdominal aortic and junctional tourniquet for hemorrhage control. AB - BACKGROUND: Specialized tourniquets have been deployed to the battlefield for the control of junctional/pelvic hemorrhage despite limited knowledge concerning their safety and duration of use. This study investigated long-term effects of abdominal application of the abdominal aortic and junctional tourniquet (AAJT) in a swine survival model. METHODS: Anesthetized spontaneously air-breathing swine were subjected to bilateral femoral artery injuries and subsequent 40% hemorrhage. Further hemorrhage was controlled by applying the AAJT on the lower abdomen for 0 h (n = 2, controls), 1 h (n = 6), 1.5 h (n = 6), or 2 h (n = 3). Before tourniquet release, arterial injuries were repaired, and mechanical ventilation and rapid crystalloid fluid were provided for at least 5 min. Additional fluid and 500 mL autologous blood were transfused after restoring blood flow. Animals were recovered and their mobility and health monitored up to 2 wk. RESULTS: AAJT application occluded the infrarenal abdominal aorta and stopped bilateral groin hemorrhage with rapid reversal of hemorrhagic shock and improved cranial blood pressure. All animals including controls recovered overnight but regaining hind leg function varied among AAJT-treated groups. In contrast to 1 h AAJT-treated swine that recovered full mobility in 1 wk, 2 h animals developed persistent hind leg paraplegia concurrent with urinary retention and ischemic necrosis of lumber muscles and had to be euthanized 3 d after surgery. Half of the 1.5-h group also had to be euthanized early due to paraplegia, whereas the other half recovered motor function within 2 wk. CONCLUSIONS: The results of this animal study indicated that ischemic reperfusion injuries associated with abdominal application of the AAJT were time-dependent. To avoid permanent injuries, AAJT application on the abdomen to control a groin hemorrhage could not be longer than 1 h. This was consistent with recent instructions for application of this tourniquet on the abdomen in patients.

PMID- 30278978 TI - Commentary: Methodological and reporting practices for laboratory studies assessing food intake using fixed and ad libitum test meals. PMID- 30278979 TI - Studying human eating behaviour in the laboratory: Theoretical considerations and practical suggestions. AB - Robinson and colleagues (2018) make important first steps in highlighting the shortcomings of laboratory studies of human eating behaviour, and providing some general suggestions to increase methodological and reporting quality. In this commentary, we present additional important theoretical considerations and practical suggestions. First, we discuss the role of situational cues in eating behaviour and highlight the implications for designing ecologically valid laboratory experiments. Next, we discuss food intake in laboratory settings in the context of the distinction between implicit and explicit measures used widely in social psychology, and provide practical recommendations to keep intake a relatively implicit measure. Finally, we recognise that designing optimal experiments requires significant resources so we present a practical procedure to recruit the smallest informative sample via Bayesian sequential hypothesis testing. PMID- 30278980 TI - Shielding disk position in intra-operative electron radiotherapy (IOERT): A Monte Carlo study. AB - PURPOSE: In IOERT breast treatments, a shielding disk is frequently used to protect the underlying healthy structures. The disk is usually composed of two materials, a low-Z material intended to be oriented towards the beam and a high-Z material. As tissues are repositioned around the shield before treatment, the disk is no longer visible and its correct alignment with respect to the beam is guaranteed. This paper studies the dosimetric characteristics of four possible clinical positioning scenarios of the shielding disk. A new alignment method for the shielding disk in the beam is introduced. Finally, it suggests a new design for the shielding disk. METHODS: As the first step, the IOERT machine "Mobetron 1000" was modeled by using Monte Carlo simulation, tuning the MC model until an excellent match with the measured PDDs and profiles was achieved. Four possible shielding disk positioning scenarios were considered, determining the dosimetric impact. Furthermore, in our center, to prevent beam misalignment, we have developed a shielding disk equipped with guiding rods. Having ascertained a correct alignment between the disk and the beam, we can propose a new internal design of the shielding disk that can improve the dose distribution with a better coverage of the treated area. RESULTS: All MC simulations were performed with a 12 MeV beam, the maximum energy of Mobetron 1000 and a 5.5 cm diameter flat tip applicator, this applicator being the most clinically used. The simulations were compared with measurements performed in a water phantom and showed good results within 2.2% of root mean square difference (RMSD). The misplacement positions of the shielding disk have dosimetric impacts in the treatment volume and a small translation could have a significant influence on healthy tissues. The D-scenario is the worst which could happens when the shielding disk is flipped upside down, giving up to 144% dose instead of 90% at the surface of the Pb/Al shielding disk. A new shielding design used, together with our alignment tool, is able to give a more homogeneous dose in the target area. CONCLUSIONS: The accuracy of shielding disk position can still be problematic in IOERT dosimetry. Any method that can ascertain the good alignment between the shielding disk and the beam is beneficial for the dose distribution and is a prerequisite for an optimized shield internal design that could improve the coverage of the treated area and the protection of healthy tissues. PMID- 30278982 TI - Monte Carlo dose verification of VMAT treatment plans using Elekta Agility 160 leaf MLC. AB - In this study, we verified volumetric modulated arc therapy (VMAT) plans in an Elekta Synergy system with an integrated Agility 160-leaf multileaf collimator (MLC) by comparing them with Monte Carlo (MC)-calculated dose distributions using the AAPM TG-119 structure sets. The head configuration of the linear accelerator with the integrated MLC was simulated with the EGSnrc/BEAMnrc code. Firstly, the dosimetric properties of the MLC were evaluated with the MC technique and film measurements. Next, VMAT plans were created with the Pinnacle3 treatment planning system (TPS) for four regions in the AAPM TG-119 structures. They were then verified by comparing them with MC-calculated dose distributions using dose volume histograms (DVHs) and three-dimensional (3D) gamma analysis. The MC simulations for the Agility MLC dosimetric properties were in acceptable agreement with measurements. TPS-VMAT plans using TG-119 structure sets agreed with MC dose distributions within 2% in the comparison of D95 in planning target volumes (PTVs) evaluated from DVHs. In contrast, higher dose regions such as D20, D10, and D5 in PTVs for TPS tended to be smaller than MC values. This tendency was particularly noticeable for mock head and neck with complicated structures. In 3D gamma analysis, the passing rates with 3%/3mm criteria in PTVs were >=99%, except for mock head and neck (89.5%). All passing rates for organs at risk (OARs) were in acceptable agreement of >96%. It is useful to verify dose distributions of PTVs and OARs in TPS-VMAT plans by using MC dose calculations and 3D gamma analysis. PMID- 30278981 TI - Physical parameter optimization scheme for radiobiological studies of charged particle therapy. AB - We have developed an easy-to-implement method to optimize the spatial distribution of a desired physical quantity for charged particle therapy. The basic methodology requires finding the optimal solutions for the weights of the constituent particle beams that together form the desired spatial distribution of the specified physical quantity, e.g., dose or dose-averaged linear energy transfer (LETd), within the target region. We selected proton, 4He ion, and 12C ion beams to demonstrate the feasibility and flexibility of our method. The pristine dose Bragg curves in water for all ion beams and the LETd for proton beams were generated from Geant4 Monte Carlo simulations. The optimization algorithms were implemented using the Python programming language. High-accuracy optimization results of the spatial distribution of the desired physical quantity were then obtained for different cases. The relative difference between the real value and the expected value of a given quantity was approximately within +/-1.0% in the whole target region. The optimization examples include a flat dose spread out Bragg peak (SOBP) for the three selected ions, an upslope dose SOBP for protons, and a downslope dose SOBP for protons. The relative difference was approximately within +/-2.0% for the case with a flat LETd (target value = 4 keV/um) distribution for protons. These one-dimensional optimization algorithms can be extended to two or three dimensions if the corresponding physical data are available. In addition, this physical quantity optimization strategy can be conveniently extended to encompass biological dose optimization if appropriate biophysical models are invoked. PMID- 30278983 TI - High resolution hard X-ray 3D mapping of a Macaca fascicularis eye: A feasibility study without contrast agents. AB - Several complementary methods able to visualize the internal structures of eyes are used in the clinical practice in the diagnosis of pathologies affecting a specific zone of the eye. Despite the significant technological progress, the visualization of the entire eyeball at micrometric resolution is yet an unsolved task both in clinical diagnostics and in laboratory research. With this respect, high resolution 3D images of the eyeball would be extremely useful, in the study of various pathologies of the retina, the lens, and of the optic nerve. In this work we combined the state-of-the-art of micro computed tomography technology with phase-contrast imaging, a recent highly sensitive technique well adapted to investigate soft tissues without the use of contrast agents; we applied the technique in the post-mortem analysis of monkey eyes, which share several similitudes with the human organ. We reported here vascular, nervous and anatomical details of monkey eyes imaged with a 3.1 * 3.1 * 3.1 um3 voxel size as well as the first 3D visualisation of the entire globe of Macaca's fascicularis eye. Results have also been compared with, and validated by, histological analysis. PMID- 30278984 TI - Adherence to APSA activity restriction guidelines and 60-day clinical outcomes for pediatric blunt liver and splenic injuries (BLSI). AB - BACKGROUND: After NOM for BLSI, APSA guidelines recommend activity restriction for grade of injury +2 in weeks. This study evaluates activity restriction adherence and 60 day outcomes. METHODS: Non-parametric tests and logistic regression were utilized to assess difference between adherent and non-adherent patients from a 3-year prospective study of NOM for BLSI (<=18 years). RESULTS: Of 1007 children with BLSI, 366 patients (44.1%) met the inclusion criteria of a completed 60 day follow-up; 170 (46.4%) had liver injury, 159 (43.4%) had spleen injury and 37 (10.1%) had both. Adherence to recommended activity restriction was claimed by 279 (76.3%) patients; 49 (13.4%) reported non-adherence and 38 (10.4%) patients had unknown adherence. For 279 patients who adhered to activity restrictions, unplanned return to the emergency department (ED) was noted for 35 (12.5%) with 16 (5.7%) readmitted; 202 (72.4%) returned to normal activity by 60 days. No patient bled after discharge. There was no statistical difference between adherent patients (n = 279) and non-adherent (n = 49) for return to ED (chi2 = 0.8 [p < 0.4]) or readmission (chi2 = 3.0 [p < 0.09]); for 216 high injury grade patients, there was no difference between adherent (n = 164) and non adherent (n = 30) patients for return to ED (chi2 = 0.6 [p < 0.4]) or readmission (chi2 = 1.7 [p < 0.2]). CONCLUSION: For children with BLSI, there was no difference in frequencies of bleeding or ED re-evaluation between patients adherent or non-adherent to the APSA activity restriction guideline. LEVEL OF EVIDENCE: Level II, Prognosis. PMID- 30278985 TI - Prognostic utility of noninvasive estimates of pulmonary vascular compliance in neonates with congenital diaphragmatic hernia. AB - AIM: To evaluate echocardiographic indices of pulmonary vascular resistance and right ventricular (RV) function in predicting death or ECMO in congenital diaphragmatic hernia (CDH). METHODS: In this single center study, early (<48 h) echocardiograms of neonates with CDH (n = 47) were reviewed by a single reader for the ratio of tricuspid regurgitant velocity to velocity time integral at the pulmonary valve (TRV/VTIpv), TRV2/VTIpv, RV fractional area change (FAC) and tricuspid annular plane systolic excursion (TAPSE). Receiver operating characteristic curves were generated for each parameter to obtain optimal cutoff values. RESULTS: Infants who died or received ECMO (n = 30) had significantly higher TRV/VTIpv and TRV2/VTIpv, and lower VTIpv, RV FAC and TAPSE, compared to the 17 survivors without ECMO. For TRV2/VTIpv and TRV/VTI at cutoffs of 1.3 and 0.38 respectively, the sensitivities were 92.3 (95% CI 75-99.1%) and 96 (95% CI 80.4-99.9%), specificities were 78.6 (49.2-95.4%) and 71.4 (42-91.6%), positive predictive values were 89 (75-95.6%) and 86.2 (73.2-93.5%) and negative predictive values were 84.6 (58.5-95.5%) and 90.9 (58.7-98.6%). CONCLUSION: Early echocardiographic evidence of pulmonary hypertension and RV dysfunction predicts outcome in CDH. Further studies utilizing these indices to guide therapeutic decision-making are warranted. LEVEL OF EVIDENCE: Level 1 for diagnostic study. PMID- 30278986 TI - Margin status and long-term prognosis of primary pancreatic neuroendocrine tumor after curative resection: Results from the US Neuroendocrine Tumor Study Group. AB - BACKGROUND: The impact of margin status on resection of primary pancreatic neuroendocrine tumors has been poorly defined. The objectives of the present study were to determine the impact of margin status on long-term survival of patients with pancreatic neuroendocrine tumors after curative resection and evaluate the impact of reresection to obtain a microscopically negative margin. METHODS: Patients who underwent curative-intent resection for pancreatic neuroendocrine tumors between 2000 and 2016 were identified at 8 hepatobiliary centers. Overall and recurrence-free survival were analyzed relative to surgical margin status using univariable and multivariable analyses. RESULTS: Among 1,020 patients, 866 (84.9%) had an R0 (>1 mm margin) resection, whereas 154 (15.1%) had an R1 (<=1 mm margin) resection. R1 resection was associated with a worse recurrence-free survival (10-year recurrence-free survival, R1 47.3% vs R0 62.8%, hazard ratio 1.8, 95% confidence interval 1.2-2.7, P = .002); residual tumor at either the transection margin (R1t) or the mobilization margin (R1m) was associated with increased recurrence versus R0 (R1t versus R0: hazard ratio 1.8, 95% confidence interval 1.0-3.0, P = .033; R1m versus R0: hazard ratio 1.3, 95% confidence interval 1.0-1.7, P = .060). In contrast, margin status was not associated with overall survival (10-year overall survival, R1 71.1% vs R0 71.8%, P = .392). Intraoperatively, 539 (53.6%) patients had frozen section evaluation of the surgical margin; 49 (9.1%) patients had a positive margin on frozen section analysis; 38 of the 49 patients (77.6%) had reresection, and a final R0 (secondary R0) margin was achieved in 30 patients (78.9%). Extending resection to achieve an R0 status remained associated with worse overall survival (hazard ratio 3.1, 95% confidence interval 1.6-6.2, P = .001) and recurrence-free survival (hazard ratio 2.6, 95% confidence interval 1.4-5.0, P = .004) compared with primary R0 resection. On multivariable analyses, tumor-specific factors, such as cellular differentiation, perineural invasion, Ki-67 index, and major vascular invasion, rather than surgical margin, were associated with long-term outcomes. CONCLUSION: Margin status was not associated with long-term survival. The reresection of an initially positive surgical margin to achieve a negative margin did not improve the outcome of patients with pancreatic neuroendocrine tumors. Parenchymal-sparing pancreatic procedures for pancreatic neuroendocrine tumors may be appropriate when feasible. PMID- 30278987 TI - Non-Viral Delivery To Enable Genome Editing. AB - Genome-editing technologies such as zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENS), and the clustered regularly interspaced short palindromic repeat (CRISPR)-associated protein system have revolutionized biological research. Each biotechnology consists of a DNA-binding protein that can be programmed to recognize and initiate double-strand breaks (DSBs) for site-specific gene modification. These technologies have the potential to be harnessed to cure diseases caused by aberrant gene expression. To be successful therapeutically, their functionality depends on their safe and efficient delivery into the cell nucleus. This review discusses the challenges in the delivery of genome-editing tools, and highlights recent innovations in non viral delivery that have potential to overcome these limitations and advance the translation of genome editing towards patient care. PMID- 30278988 TI - Redox cell signaling and hepatic progenitor cells. AB - Hepatic diseases are widespread in the world and organ transplantation is currently the only treatment for liver failure. New cell-based approaches have been considered, since stem cells may represent a possible source to treat liver diseases. Acute and chronic liver diseases are characterized by high production of reactive oxygen and nitrogen species, with consequent oxidative modifications of cellular macromolecules and alteration of signaling pathways, metabolism and cell cycle. Although considered harmful molecules, reactive species are involved in cell growth and differentiation processes, modulating the activity of transcription factors, which take part in stemness/proliferation. It is conceivable that redox balance may regulate the development of hepatic progenitor cells, function and survival in synchrony with metabolism during chronic liver diseases. This review aims to summarize diverse redox-sensitive signaling pathways involved in stem cell fate, highlighting the important role of hepatic progenitor cells as a possible source to treat end-stage liver disease for organ regeneration.

PMID- 30278990 TI - Hypercholesterolemia impairs megakaryopoiesis and platelet production in scavenger receptor BI knockout mice. AB - BACKGROUND AND AIMS: Thrombocytopenia in scavenger receptor BI (SR-BI) knockout mice is suggested to result from augmented platelet clearance induced by elevated intracellular unesterified cholesterol (UC) levels. We hypothesize that SR-BI deficiency may also influence platelet production at the level of its precursor cell in the bone marrow, the megakaryocyte. METHODS: In this study, we compared megakaryopoiesis and platelet production in SR-BI knockout and wild-type mice. RESULTS: In line with our hypothesis, megakaryocytes from SR-BI knockout mice exhibited UC accumulation while no accumulation of UC was detectable in wild-type megakaryocytes. Bone marrow expression of transcription factors involved in megakaryocyte maturation was induced, but megakaryocyte counts were unchanged in bone marrow of SR-BI knockout mice. Interestingly, we did find a striking 62% decrease (p < 0.01) in proplatelet production by SR-BI knockout megakaryocytes. SR-BI knockout mice displayed an impaired increase in circulating platelet concentrations and bone marrow megakaryocyte numbers upon thrombopoietin challenge. Importantly, megakaryocytes from normolipidemic bone marrow-specific SR-BI knockout mice exhibited a normal ability to produce proplatelets. Moreover, bone marrow-specific deletion of SR-BI did not impair the thrombopoietin response or induce thrombocytopenia, confirming that absence of megakaryocyte SR-BI does not underlie the thrombocytopenic phenotype in total body SR-BI knockout mice. CONCLUSIONS: In conclusion, the elevation of plasma unesterified cholesterol levels impairs megakaryopoiesis and platelet production in SR-BI knockout mice. Our findings suggest that, in addition to an increased platelet clearance, a decrease in platelet production may also, in part, explain the thrombocytopenic phenotype associated with SR-BI deficiency in mice. PMID- 30278991 TI - Rebalancing health systems toward community-based care: The role of subsectoral politics. AB - There has been increased policy discourse urging a "rebalancing" of health systems from institutionally-based to community-based approaches. This paper offers an analysis of the subsectoral dynamics that condition opportunities to strengthen community-based care relative to acute care. We report on the results of a policy study in Ontario, Canada that explored factors impacting on the capacity to expand community-based care. In so doing, we highlight the challenges associated with the community subsector's ability to develop 'critical' status and challenge the dominance of the acute subsector. We conclude that attempts to rebalance health systems toward community-based care should begin by understanding that health care is not a monolithic policy sector, but rather a collection of proximate policy sub-sectors, inclusive of community care, acute care, and institutional care, each with their own internal characteristics and dynamics that impact sectoral directions. PMID- 30278992 TI - Distinct brain areas process novel and repeating tone sequences. AB - The auditory dorsal stream has been implicated in sensorimotor integration and concatenation of sequential sound events, both being important for processing of speech and music. The auditory ventral stream, by contrast, is characterized as subserving sound identification and recognition. We studied the respective roles of the dorsal and ventral streams, including recruitment of basal ganglia and medial temporal lobe structures, in the processing of tone sequence elements. A sequence was presented incrementally across several runs during functional magnetic resonance imaging in humans, and we compared activation by sequence elements when heard for the first time ("novel") versus when the elements were repeating ("familiar"). Our results show a shift in tone-sequence-dependent activation from posterior-dorsal cortical areas and the basal ganglia during the processing of less familiar sequence elements towards anterior and ventral cortical areas and the medial temporal lobe after the encoding of highly familiar sequence elements into identifiable auditory objects.

AB - In Baffin Bay and Davis Strait, reports indicate that Northern Fulmars (Fulmarus glacialis) are vulnerable to bycatch in the fisheries for Greenland Halibut (Reinhardtius hippoglossoides). We modeled the potential current and future impacts the expanding halibut fishery may have on fulmar populations in the region using population viability analysis. By varying age-specific bycatch vulnerability, detectability, and the size of the at-risk population, we tested how different scenarios may influence population trajectories. From 2011 to 2015, the bycatch rate of fulmars was approximately 212 (SD +/- 111) individuals per year. This could cause declines (-12%) over three generations (66 years) at the three colonies closest to the fishing grounds. However, declines could be as high as -33% over this same period if unobservable bycatch is considered, and as low as -0.4% if bycatch is distributed among a larger population. Several uncertainties we modeled could be reduced by improving how bycatch data are recorded by at-sea observer programs. PMID- 30278995 TI - Differential expression of mTOR signaling pathway proteins in lichen planopilaris and frontal fibrosing alopecia. AB - Dysregulation of the mammalian target of rapamycin (mTOR) signaling pathway has a variety of effects on the immune system and stem cell proliferation. Lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) are inflammatory scalp conditions resulting in permanent alopecia, which are thought to be related to stem cell damage. Here we investigate the expression of mTOR signaling pathway proteins in human hair follicles of LPP and FFA patients. The expression of mTOR pathway proteins in biopsy specimens from lesional and non-lesional scalp areas of eight LPP and five FFA patients were compared to control scalp biopsies from patients undergoing surgical excisions of sebaceous cysts. We performed immunohistochemical evaluation using a panel of antibodies including mTOR, phospho-mTOR (Ser2448), phospho-p70S6K (Thr389), phospho-4EBP1 (Thr37146), and phospho-tuberin (T1462), as well as Western blot analysis for phospho-p70S6K (Thr389) expression. All evaluated mTOR pathway proteins were similarly expressed in the control and patient non-lesional scalps. While mTOR expression did not show significant alterations between the groups, p-mTOR, p-p70S6K, p-4EBP1, and p tuberin expressions decreased in the interfollicular epidermis in the lesional scalps of patients. p-p70S6K and p-4EBP1 expression decreased in the outer root sheath (ORS) and inner root sheath (IRS) of the bulge of hair follicles in the lesional scalps of patients. p-mTOR and p-p70S6K expression increased in the lower follicle ORS and bulb of the hair follicles, and p-4EBP1 expression decreased in the bulb of the hair follicles in the lesional scalps of patients. Phospho-tuberin expression increased in the IRS of the bulge and lower follicle ORS of the hair follicles in the lesional scalps of patients, whereas its expression decreased in the bulb. Our results indicate that the mTOR signaling pathway proteins are localized throughout normal hair follicles and that expression of mTOR signaling pathway proteins is altered in the hair follicles of LPP and FFA patients. Further research is required to understand the mechanism by which mTOR operates in the pathogenesis of these diseases. PMID- 30278996 TI - Impact of right upper quadrant cytoreductive techniques with extensive liver mobilization on postoperative hepatic function and risk of liver failure in patients with advanced ovarian cancer. AB - OBJECTIVE: Evaluate postoperative hepatic-function in patients with advanced ovarian cancer (OC) who underwent extensive right upper-quadrant (RUQ) cytoreduction in primary, relapsed or interval settings. METHODS: We retrospectively reviewed all patients with OC who underwent liver resection, mobilization and/or diaphragmatic-stripping between 01/2013 and 12/2016. Postoperative liver enzyme function (LFTs), assessed by alanine transaminase (ALT), alkaline phosphatase (ALP) and bilirubin (Bil), was correlated with postoperative complications. RESULTS: 132 patients were identified. 81 patients (61%) underwent upfront, 25(19%) interval and 26(20%) secondary cytoreduction. The surgical procedures were right diaphragmatic peritoneal stripping (81/132;61%), full-thickness resection (42/132;32%), liver-capsule resection (85/132;64%), porta-hepatis tumor resection (11/132;8%) and partial hepatectomy (5/132;4%). 74%(98/132) of patients increased their LFTs postoperatively with a peak at 24-hours. Highest ALT median was 1.7-fold of upper normal limit (UNL), with the highest ALT value rising up to 28-fold UNL on the 1st postoperative day (PoD)(range 6-1792 IU/L). Median value of highest ALP was within normal, with the highest ALP value rising up to 4-fold UNL on PoD 5(range 22-512 IU/L). Median value of highest Bilirubin level was also within normal, with highest Bilirubin level rising up to 6-fold UNL on PoD 5(range: 2-120 MUmol/L). Mean LFT normalization time was 7 days (range: 3-14 days). No significant morbidity was directly linked to LFT deterioration, apart from one case (0.8%) of fatal fulminant hepatic-failure. CONCLUSION: RUQ-cytoreduction is almost always associated with a transient LFT-increase, with no significant clinical implications and spontaneous normalization within the first postoperative week. Due to the existing risk of fulminant liver failure, albeit rare and difficult to predict, postoperatively elevated LFTs should be monitored, until normalization. Large prospective studies are required to assess the predictive value of LFTs and other risk factors for postoperative hepatic failure in patients with OC undergoing extensive RUQ-cytoreduction. PMID- 30278997 TI - Programmed cell death ligand 1 expression is upregulated in the skeletal muscle of patients with myasthenia gravis. AB - We investigated the expression patterns of programmed cell death-ligand 1 (PD-L1) in the skeletal muscle of 15 patients with myasthenia gravis (MG). In 11 of the patients, immunohistochemistry confirmed the localization of PD-L1 in the muscle cell membrane with cytoplasmic integrity. PD-L1 mRNA expression levels were higher in the muscles of MG patients as compared to those of non-myogenic patients (p < .05). Moreover, a unimodal relationship between PD-L1 mRNA levels and quantitative MG scores for disease severity was identified by a generalized additive model, indicating reciprocal effects. Together, these results suggest that MG symptoms might influence PD-L1 expression in muscle cells, and upregulated PD-L1 expression might inhibit autoimmune reactivity. PMID- 30278998 TI - Is STM involved in sentence comprehension? AB - We discuss the literature concerning the role of auditory-verbal short-term memory (phonological loop) in sentence comprehension. We critically analyze data concerning patients with a selective deficit of the phonological loop, then we examine aphasic patients with deficit of auditory-verbal short-term memory and we consider the effect of STM treatment on sentence comprehension. Finally, results from imaging and TMS studies are discussed. In our opinion, data from the literature suggest that both components of the phonological loop are involved in the comprehension of some type of sentence, namely syntactically complex sentences that load on memory, such as center-embedded object relative clauses. However, it is crucial to investigate further patients with a selective STM impairment or aphasic patients, by using extensive and sophisticated experimental material.

PMID- 30279000 TI - Surgical myectomy versus alcohol septal ablation for obstructive hypertrophic cardiomyopathy: A propensity score-matched cohort. AB - OBJECTIVES: In patients with hypertrophic cardiomyopathy, obstruction of the left ventricular outflow tract can be relieved by surgical septal myectomy or alcohol septal ablation, but uncertainty remains regarding long-term results and comparative effectiveness of alcohol septal ablation. This study aims to compare short- and long-term outcomes of the 2 procedures. METHODS: Between December 1998 and September 2016, 2407 patients underwent septal myectomy and 211 patients underwent alcohol septal ablation at our institution. After 2:1 propensity score matching, the study cohort included 334 patients who underwent myectomy and 167 patients who underwent alcohol septal ablation. RESULTS: Median (interquartile range) ages of patients in the myectomy and alcohol septal ablation groups were 65 (58-71) years and 64 (56-73) years (P = .9), respectively. After intervention, median resting left ventricular outflow tract gradient at predischarge transthoracic echocardiography was 0 (0-10) mm Hg in the myectomy group (n = 288) and 21 (10-60) mm Hg in the alcohol septal ablation group (n = 63) (P < .001, tested at baseline gradients of 30 and 50 mm Hg). There were no differences in survival between the 2 groups (risk of death for alcohol septal ablation vs myectomy, hazard ratio, 1.5; 95% confidence interval, 0.9-2.6; P = .1). Survival of patients undergoing septal myectomy was better than that of an age-, sex-, and race-matched US population (82% vs 75% at 12 years, P = .01). Reintervention for left ventricular outflow tract obstruction was more likely to occur in patients who received alcohol septal ablation (hazard ratio, 33.3; 95% confidence interval, 4.4-250.6; P < .001). CONCLUSIONS: There were no differences in survival of patients undergoing myectomy or alcohol septal ablation, but freedom from reintervention and early and late reduction of left ventricular outflow tract gradient are superior in patients undergoing septal myectomy. PMID- 30279001 TI - Potential roles of neurotensin on cognition in conditions of obese-insulin resistance. AB - Neurotensin is an endogenous tridecapeptide that can be found in both central and peripheral nervous systems. Under normal physiological conditions, neurotensin is involved in the regulation of pain, body temperature, physical activity, appetite as well as learning and memory. In addition, it plays an important role in fat metabolism. Previous studies have demonstrated that alterations of neurotensin levels were associated with several neuropathological conditions such as Alzheimer's disease, mood disorders, and obesity associated eating disorders. Obesity has been shown to be associated with low-grade systemic inflammation, brain inflammation, and cognitive decline. Several pieces of evidence suggest that neurotensin might play a role in cognitive decline following obesity. However, the underlying mechanisms of neurotensin on cognition under obese insulin resistant condition are still unclear. In this review, the current available evidence from in vitro, in vivo and clinical studies regarding the role of neurotensin in the physiological condition and obesity in association with cognition are comprehensively summarized and discussed. The studies which report controversial findings regarding these issues are also presented and discussed. PMID- 30279002 TI - Machine learning in human movement biomechanics: Best practices, common pitfalls, and new opportunities. AB - Traditional laboratory experiments, rehabilitation clinics, and wearable sensors offer biomechanists a wealth of data on healthy and pathological movement. To harness the power of these data and make research more efficient, modern machine learning techniques are starting to complement traditional statistical tools. This survey summarizes the current usage of machine learning methods in human movement biomechanics and highlights best practices that will enable critical evaluation of the literature. We carried out a PubMed/Medline database search for original research articles that used machine learning to study movement biomechanics in patients with musculoskeletal and neuromuscular diseases. Most studies that met our inclusion criteria focused on classifying pathological movement, predicting risk of developing a disease, estimating the effect of an intervention, or automatically recognizing activities to facilitate out-of-clinic patient monitoring. We found that research studies build and evaluate models inconsistently, which motivated our discussion of best practices. We provide recommendations for training and evaluating machine learning models and discuss the potential of several underutilized approaches, such as deep learning, to generate new knowledge about human movement. We believe that cross-training biomechanists in data science and a cultural shift toward sharing of data and tools are essential to maximize the impact of biomechanics research. PMID- 30279003 TI - Refining Early Antitumoral Drug Development. AB - The failure rate of development of new drugs in oncology is high, with up to 95% of drugs tested in Phase I not reaching the market. Causes behind this high failure rate are discussed here, and solutions to increase the success in the development of antitumor drugs are suggested. PMID- 30279004 TI - FGL2 prothrombinase contributes to the early stage of coronary microvascular obstruction through a fibrin-dependent pathway. AB - BACKGROUND: Membrane-associated fibrinogen-like protein 2 (FGL2 prothrombinase, pFGL2) is abundantly expressed in activated microvascular endothelial cells (MVECs) and plays a crucial role in microthrombus formation in microcirculatory vasculature. It has been widely reported that coronary microvascular obstruction (CMVO) contributes to adverse outcomes following myocardial ischemia/reperfusion. However, the role of pFGL2 in CMVO is poorly understood. METHODS AND RESULTS: We aimed to identify the effect of MVECs-pFGL2 in CMVO using FGL2 knockout mice. As results, the MVECs-pFGL2 expression progresses significantly over 3 days and then gradually decreases, which is positively correlated with the extent of CMVO as detected by HE staining in wild type mice. Furthermore, FGL2 deficiency is correlated with decreased areas of no-reflow and necrosis as detected by Evans Blue and TTC staining and that it ameliorates cardiac dysfunction detected by hemodynamics in the early stage of CMVO. Moreover, fibrin deposition in microvasculature is significantly reduced in FGL2-deficient mice as evidenced by immunohistochemistry, MSB and Carstairs staining, along with the down-regulation of leukocyte adhesion and infiltration. Additionally, we observed that the FGL2 deficiency decreases macrophage infiltration and shifts the macrophage phenotype from pro-inflammatory (M1,) to anti-inflammatory (M2,) pattern in the early stage of CMVO. CONCLUSION: These findings highlight the MVECs-pFGL2-fibrin pathway in the early stage of CMVO and provide insights into coagulation and inflammation for the coronary artery disease therapeutics.

PMID- 30279005 TI - Sarcomere-based genetic enhancement of systolic cardiac function in a murine model of dilated cardiomyopathy. AB - Diminished cardiac contractile function is a characteristic feature of dilated cardiomyopathy (DCM) and many other heart failure (HF) causing etiologies. We tested the hypothesis that targeting the sarcomere to increase cardiac contractility can effectively prevent the DCM phenotype in muscle-LIM protein knockout (MLP-/-) mice. The ablation of cardiac myosin binding protein C (MYBPC3 /-) protected the MLP-/- mice from developing the DCM phenotype. We examined the in vivo cardiac function and morphology of the resultant mouse model lacking both MLP and MYBPC3 (DKO) by echocardiography and pressure-volume catheterization and found a significant reduction in hypertrophy, as evidenced by normalized wall thickness and chamber dimensions, and improved systolic function, as evidenced by enhanced ejection fraction (~26% increase compared MLP-/- mice) and rate of pressure development (DKO 7851.0 +/- 504.8 vs. MLP-/- 4496.4 +/- 196.8 mmHg/s). To investigate the molecular basis for the improved DKO phenotype we performed mechanical experiments in skinned myocardium isolated from WT and the individual KO mice. Skinned myocardium isolated from DKO mice displayed increased Ca2+ sensitivity of force generation, and significantly accelerated rate of cross bridge detachment (+63% compared to MLP-/-) and rate of XB recruitment (+58% compared to MLP-/-) at submaximal Ca2+ activations. The in vivo and in vitro functional enhancement of DKO mice demonstrates that enhancing the sarcomeric contractility can be cardioprotective in HF characterized by reduced cardiac output, such as in cases of DCM. PMID- 30279008 TI - [Von Willebrand disease]. AB - Von Willebrand factor is involved in primary hemostasis (adhesion of platelets to subendothelium and platelet aggregation) and acts as the carrier of coagulation factor VIII. Von Willebrand disease, resulting from a quantitative or qualitative defect of this factor, is the most frequent inherited bleeding disorder. It is mainly responsible for symptoms such as mucocutaneous bleeding and excessive bleeding after trauma or invasive procedures, but can also cause gastro intestinal bleeding or hemarthrosis in the most severe forms of the disease. There are numerous causes of physiological variation of von Willebrand factor plasma levels which can be responsible for diagnostic difficulty or changes in symptoms over time. Diagnosis relies primarily on clinical symptoms but requires the use of several laboratory analyses: von Willebrand factor activity and antigen testing and factor VIII activity. More specialized assays allow classification of the disease in various types and subtypes which imply different management strategies (types 1, 2A, 2B, 2M, 2N, and 3). Treatment is based on desmopressin, responsible for an increase in plasma concentration of von Willebrand factor, and plasma-derived von Willebrand factor concentrates which can be combined with factor VIII.

PMID- 30279010 TI - LncRNA TP73-AS1 accelerates tumor progression in gastric cancer through regulating miR-194-5p/SDAD1 axis. AB - BACKGROUND: Long noncoding RNAs (lncRNAs) have been considered as significant regulators in many cancer progression, such as proliferation, invasion and other path of evolution. Nevertheless, we have not had a grasp of the role of lncRNA TP73-AS1 in gastric cancer (GC). METHODS: qRT-PCR analysis was first conducted to examine the TP73-AS1 level in both GC tissues and cell lines. Then gain or loss of-function assays were carried out to detect the effect of TP73-AS1 on GC development. In mechanism, bioinformatics analysis and luciferase reporter assays were used to search and confirm the target gene of TP73-AS1. Finally, rescue assays were performed to confirm the influence of TP73-AS1-miR-194-5p-SDAD1 axis on GC development. RESULTS: TP73-AS1 was upregulated in GC tissues and cell lines. Furthermore, TP73-AS1 exerted oncogenic role in GC through promoting cell growth and metastasis. In addition, TP73-AS1 was certified as a ceRNA by regulating miR-194-5p/SDAD1 axis. CONCLUSIONS: TP73-AS1 accelerates tumor progression in gastric cancer through regulating miR-194-5p/SDAD1 axis. PMID- 30279011 TI - Extrapolation of Normative KOOS, JR Data for the Young Patient Population Undergoing Knee Arthroplasty Procedures. AB - BACKGROUND: The Knee Injury and Osteoarthritis Outcome (KOOS), JR is a patient reported outcome measure that is validated for patients undergoing total knee arthroplasty. The objective of this study was to provide normative data for the KOOS, JR in a relatively healthy US population visiting an outpatient orthopedic setting. This study is a cross-sectional study. METHODS: Normative data from the KOOS questionnaire was used to calculate the subscale (pain, activity of daily living, and symptoms), raw, and interval scores for the KOOS, JR. The participants who completed the KOOS were devoid of current complaints of the hip, knee, and ankle. The means, standard deviations, medians, interquartile ranges, and percentiles for the KOOS, JR subscale, raw and interval scores were calculated by age decades, sex, laterality, and history of knee injuries in the past year. RESULTS: Four hundred two men and 598 women were involved in the analysis. The lowest mean interval scores were noted in the 56- to 64-year group with the greatest disparity between male and female compared to the rest of the age cohorts. Females scored high in all 3 subscales with a higher score in the pain subscale, denoting a lower normative value. Patients with hypertension scored with a significantly lower mean interval score than those without hypertension. In all subscales, tobacco use and hypertension were associated with a statistically significant negative effect on the normative scores. CONCLUSION: The normative values for the KOOS, JR can be used to set goals and follow the progress of patient satisfaction in regard to the knee after a knee arthroplasty procedure.

AB - BACKGROUND: Non-muscle-invasive bladder cancer (NMIBC) has a significant risk of recurrence despite adjuvant intravesical therapy. OBJECTIVE: To determine whether celecoxib, a cyclo-oxygenase 2 inhibitor, reduces the risk of recurrence in NMIBC patients receiving standard treatment. DESIGN, SETTING, AND PARTICIPANTS: BOXIT (CRUK/07/004, ISRCTN84681538) is a double-blinded, phase III, randomised controlled trial. Patients aged >=18 yr with intermediate- or high-risk NMIBC were accrued across 51 UK centres between 1 November 2007 and 23 July 2012. INTERVENTION: Patients were randomised (1:1) to celecoxib 200mg twice daily or placebo for 2 yr. Patients with intermediate-risk NMIBC were recommended to receive six weekly mitomycin C instillations; high-risk NMIBC cases received six weekly bacillus Calmette-Guerin and maintenance therapy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was time to disease recurrence. Analysis was by intention to treat. RESULTS AND LIMITATIONS: A total of 472 patients were randomised (236:236). With median follow-up of 44 mo (interquartile range: 36-57), 3-yr recurrence-free rate (95% confidence interval) was as follows: celecoxib 68% (61-74%) versus placebo 64% (57-70%; hazard ratio [HR] 0.82 [0.60-1.12], p=0.2). There was no difference in high-risk (HR 0.77 [0.52 1.15], p=0.2) or intermediate-risk (HR 0.90 [0.55-1.48], p=0.7) NMIBC. Subgroup analysis suggested that time to recurrence was longer in pT1 NMIBC patients treated with celecoxib compared with those receiving placebo (HR 0.53 [0.30 0.94], interaction test p=0.04). The 3-yr progression rates in high-risk patients were low: 10% (6.5-17%) and 9.7% (6.0-15%) in celecoxib and placebo arms, respectively. Incidence of serious cardiovascular events was higher in celecoxib (5.2%) than in placebo (1.7%) group (difference +3.4% [-0.3% to 7.2%], p=0.07). CONCLUSIONS: BOXIT did not show that celecoxib reduces the risk of recurrence in intermediate- or high-risk NMIBC, although celecoxib was associated with delayed time to recurrence in pT1 NMIBC patients. The increased risk of cardiovascular events does not support the use of celecoxib. PATIENT SUMMARY: Celecoxib was not shown to reduce the risk of recurrence in intermediate- or high-risk non-muscle invasive bladder cancer (NMIBC), although celecoxib was associated with delayed time to recurrence in pT1 NMIBC patients. The increased risk of cardiovascular events does not support the use of celecoxib. PMID- 30279016 TI - [Tuberculosis in older persons in African setting: Epidemiological, diagnostic and evolutive features]. AB - OBJECTIVE: To determine the epidemiological, diagnostic and evolutives features of tuberculosis (TB) in older subjects in Benin. PATIENTS AND METHODS: This was a retrospective cohort study of adults TB patients (age>=15 years) who were notified at all the Basic Management Units (BMU) in Benin from January 1st, 2013 to December 31st. Older subjects (age>=60 years) were compared to those less than 60 years named young subjects. The threshold of significance was set at 5%. RESULTS: The analysis was carried out on 6531 cases adults cases notified during the period. 601 (9.2%) were 60 years old or above. The case notification rate (CNR) in elders was more than twice the CNR in young people (68 cases vs. 31 cases per 100,000 population). Older subjects were less often infected with HIV (9.3%) than young's (16.7%), P<0.0001. In new bacteriologically confirmed pulmonary TB negative for HIV, unfavorable treatment outcomes were more frequent in older subjects than in young subjects with more deaths (7.5% vs. 3.0%). On the other hand, in bacteriological confirmed TB seropositive for HIV and all the other cases, treatment outcomes were comparable between the two groups. CONCLUSION: The high CNR and the high death rate in older subjects should plead for a specific care for an adapted management of TB case in this group. PMID- 30279017 TI - Incidence and predictors of health care-associated infections among patients colonized with carbapenem-resistant Enterobacteriaceae. AB - Colonization with carbapenem-resistant Enterobacteriaceae (CRE) precedes invasive infections. Neither the actual risk for the latter nor the route between the 2 stages is completely clear. We studied a retrospective cohort of patients hospitalized between 2013-2016 and colonized with CRE. The incidence of CRE health care-associated infections was 13.2%, and predictors were the presence of a urinary catheter and the use of carbapenems. Infection prevention strategies in CRE-colonized patients should focus on invasive devices and antimicrobial stewardship. PMID- 30279018 TI - High incidence of persistent subtherapeutic levels of the most common AEDs in children with epilepsy receiving polytherapy. AB - BACKGROUND: Low levels of AEDs can be secondary drug-drug interactions or related to irregular intake due to poor treatment adherence. This latter behavior is highly suspected in ambulatory pediatric epileptic patients when controls of AEDs are subtherapeutic. However, it cannot be considered for inpatients during long periods of hospitalization. A few isolated case reports have documented persistent low levels (PLL) of AEDs in hospitalized epileptic children, but no population study has currently been reported. OBJECTIVE: The aim of this study was to document the incidence of PLL of the most common AEDs - phenytoin (PHT), phenobarbital (PHB), valproic acid (VA), and carbamazepine (CBZ) - in pediatric epileptic in- and outpatients (PEP). METHODS: 21,040 plasma levels of the aforementioned AEDs from 3279 PEP were retrospectively analyzed. Plasma levels of AEDs were measured by an automated method using trademarked commercial kits with their corresponding quality control programs. Randomized samples were also controlled by HPLC methods. Only cases with more than 3 controls were included in the study. RESULTS: A high rate of PLL of PHT was detected in in- (71.7%) and outpatients (74.1%), while PLL of PHB, VA, and CBZ were detected in a lower proportion. Rates of PLL of PHT were similar in in- and outpatients. PLL of PHB was more commonly observed in outpatients while PLL of VA and CBZ were more frequently seen in inpatients. In some hospitalized patients receiving polytherapy, PLL of at least one AED were documented during a long time. DISCUSSION: Treatment non-adherence could be present in part of the outpatients, but cannot explain the PLL observed in a group of inpatients as described here. The recently described "pharmacokinetic hypothesis" of pharmaco-resistant epilepsy should be addressed in cases with AEDs-PLL, particularly in hospitalized cases. Perhaps, instead of stopping the subtherapeutic medication, the increasing doses of this AED and/or administration of inhibitors of CYP and P-glycoprotein, could help to achieve its therapeutic range, allowing a better pharmacologic effect and avoiding the development of more severe complications, such as status epilepticus or SUDEP. PMID- 30279019 TI - Relationship between lean body mass and isokinetic peak torque of knee extensors and flexors in severely burned children. AB - OBJECTIVE: Severe burns cause hypermetabolic responses and prolonged hospitalization, resulting in loss of body mass and muscle strength. This study aimed to determine whether long-term gains in lean body mass (LBM) after structured exercise programs are functionally meaningful and related to greater muscle strength in severely burned children. STUDY DESIGN: LBM and muscle strength were measured at discharge and at 6, 12, 24, and 36 months after burn in 349 children. Body composition, including LBM, was measured via dual-emission X ray-absorptiometry. Peak torque was measured using Biodex dynamometer at varying angular velocities (90, 120, 150, 180 degrees /s). Pearson correlation analysis evaluated the association between LBM and peak torque. RESULTS: LBM progressively increased from discharge (32.5+/-11.5kg) to 36 months following injury (40.2+/ 12.3kg). Peak torque and peak torque/LBM increased from discharge (56.4+/-34.0Nm and 1.7+/-34.0Nmkg-1) to 36 months after burn (102.3+/-43.8Nm and 2.5+/-0.7Nmkg 1, p<0.01 for both). LBM and peak torque at all angular velocities showed moderate/strong correlations, with 120 degrees /s being the strongest (all time points: R2>=0.57). CONCLUSION: In severely burned children participating in a rehabilitative exercise program, gains in LBM over time are related to increases in muscle strength, suggesting that gained muscle mass is functional. Measurement of muscle strength at an angular velocity of 120 degrees /s best reflects gains in LBM and should be considered for reliable measure of strength in future studies. PMID- 30279020 TI - Place identity, autobiographical memory and life path trajectories: The development of a place-time-identity model. AB - The ability to remember, recognize and reconstruct places is a key component of episodic autobiographical memory. In this respect, place forms an essential basis for the unfolding of experiences in memory and imagination. The autobiographical memory is seen to contribute to a sense of self and place identity. The aim of this study was to concertedly analyze paintings, autobiographical narrations and places of birth and life of clients under treatment at a psychiatric clinic in Switzerland who were manifesting psychiatric disorders, e.g. depression, anxiety disorders, bipolar disorder, personality disorder, substance dependence, and dementia. Each client exhibited distinctive attitudes and approaches towards life characterized by unique personal mental constructs for living in given places of time episodes that worked towards shaping the development of their identities as well as the development of their health. For these clients, place and time function together to leave a mark, a trajectory, that can hinder or help the resolution of a psychiatric condition. Based on six representative cases, we illustrate how each painting, each biographical narration and each interview reveals deeper structures of individual perception, emotions, feelings, coping strategies, and capacities to reflect and identify with place-time trajectories. Based on this analysis, a place-time-identity model has been developed, which emphasizes the importance of narration, the structure of personality, and emotional experiences in the development of the 'relay station' of episodic autobiographical memory, self and autonoetic consciousness: these three elements are not only connected through their embeddedness in time, but also through their embeddedness in place. In this context, place provides an external fundus of memory, capable of supporting humans in healthy recollection and remembering. The process of placing appears to contribute to the creation of self-esteem and identity. This psycho-geographical place-life-time approach is contrasted to phenomenological place-space-time theories of Husserl, Heidegger, Bachelard, and Sloterdijk.

PMID- 30279024 TI - Daptomycin for the treatment of Staphylococcus aureus infections complicated by septic pulmonary emboli. AB - The management of Staphylococcus aureus bacteremia is limited by high rates of methicillin resistance and the paucity of antibiotic agents with proven efficacy in complicated infectious syndromes, such as endocarditis. Vancomycin is the mainstay of therapy; however, salvage therapy is frequently required due to persistence of infection or drug toxicity. Daptomycin is FDA-approved for S. aureus bacteremia and right-sided endocarditis, but controversy exists regarding the role of this agent in the setting of septic pulmonary emboli. Sequestration by pulmonary surfactant renders daptomycin ineffective in bronchoalveolar pneumonia; however, the impact of this drug property on efficacy in hematogenous pulmonary infections is unclear. Herein we review the available evidence in order to inform the rationale use of daptomycin in S. aureus infections complicated by septic pulmonary emboli. PMID- 30279025 TI - The performance of galactomannan in combination with 1,3-beta-D-glucan or aspergillus-lateral flow device for the diagnosis of invasive aspergillosis: Evidences from 13 studies. AB - Galactomannan (GM), 1,3-beta-D-glucan (BDG) and aspergillus-lateral flow device (LFD) are recognized as diagnostic tools for invasive aspergillosis (IA). The combined performance of these assays, however, is inconsistent in various studies. We undertook a meta-analysis of 13 studies involving 1513 patients to evaluate the utility of GM in combination with BDG or LFD for diagnosing IA. The pooled SEN, SPE, PLR, NLR and diagnostic odds ratio (DOR) were calculated and constructed to summarize the overall combined performance. Combining both positive results of GM and BDG assays leaded to the pooled SEN 0.49 (95%CI 0.27 0.72), SPE 0.98 (95%CI 0.94-1.00), PLR 31.68 (95%CI 5.36-187.37), NLR 0.52 (95%CI 0.32-0.84) and DOR 61.23 (95%CI 6.96-538.90). Comparing with GM and BDG assays, both positive results of GM and LFD leaded to high SEN, similar SPE, low PLR and NLR. At least one positive result of GM or LFD conferred great SEN 0.93 and low NLR 0.08. Both positive results of GM and BDG or LFD assay were in favor of confirming the existence of IA. And both negative results of GM and LFD were beneficial to rule out IA. Further studies with sufficient sample size should focus on the diagnostic performance and cost-effectiveness of these combined tests in clinical setting. PMID- 30279026 TI - Peri-follicular blood flow in the follicle from which ovulation occurs in cows. AB - The hypothesis of the study was that the vascularity of ovulatory follicles (OF) determines the ovulatory status. The peri-follicular blood flow characteristics of OF were sequentially recorded using Color Doppler Imaging ultrasonography from the onset of induced estrus (Day 0) to ovulation at 12 h intervals. The OFs were categorized into two groups based on the timing of ovulation (i) Normal ovulation (OFN) - When ovulation occurred within 36 h after the onset of estrus (n = 18) and (ii) Delayed ovulation (OFD) - When ovulation occurred after 36 h (n = 15). The blood flow velocity, Doppler pulse duration (DPD) and Pulsatility index (PI) of the OF were recorded during each examination. The OF was well vascularized with a detectable blood flow signals, while the subordinate or atretic follicles were devoid of detectable blood flow. On Day 0, the DPD (874.33 +/- 56.99 ms) and PI (0.62 +/- 0.01) values were less in the OFN when compared to OFD (1140.56 +/- 27.54 ms and 1.28 +/- 0.15 respectively) group. In the OFD group, ovulation occurred between 36 and 60 h after onset of estrus when the DPD value reduced to 878.17 ms. Based on ROC analysis, it was evident that the DPD value of < 929 ms is a necessary factor for induction of ovulation. The decreased DPD and PI values of the OF on the day of estrus are positive indicators of a normal ovulation process. PMID- 30279027 TI - Apoptosis and developmental capacity of vitrified parthenogenetic pig blastocysts. AB - This study was conducted to evaluate whether the poor developmental capacity of pig embryos after vitrification was related to the occurrence of apoptosis. Parthenogenetic blastocysts were used as the research material. The blastocoel recovery rate, mitochondrial membrane potential (DeltaPsim), amount of early apoptosis, activities of several caspases, and relative abundance of mRNA of apoptosis-related genes involved in mitochondria and death receptor apoptotic pathways were detected before or after vitrification. The results indicate that the blastocoel recovery rate (31.0%) and total cells (31.8) of vitrified blastocysts were less than those of fresh blastocysts (100% and 38.2, P < 0.05). The DeltaPsim of vitrified blastocysts was 0.46, which was less than that of fresh blastocysts (1.02, P < 0.05). The rate of apoptotic cells in vitrified blastocysts (8.1%) after TUNEL (TdT-mediated dUTP Nick-End Labeling) assay was markedly greater than that in fresh blastocysts (3.9%, P < 0.05). The pan caspase, caspase-3, caspase-8 and caspase-9 activities of vitrified blastocysts (20.7, 20.6, 17.6 and 19.9) were markedly greater than those of fresh blastocysts (7.4, 6.5, 5.5 and 6.3, P < 0.05). The real-time PCR results indicated that relative abundance of caspase-8 and TNF-alpha mRNA from death receptor apoptotic pathway and caspase-9 for the mitochondrial apoptotic pathway genes in the vitrified group were greater than those in the fresh group P < 0.05). The relative abundance of Bcl-2 and SOD-1 mRNA for the mitochondrial pathway genes in the vitrified group was less than those in the fresh group (P < 0.05). In conclusion, the poor developmental capacity of vitrified parthenogenetic pig blastocysts was closely related with apoptosis. Both mitochondria and death receptor-mediated apoptotic pathways participated the occurrence of this apoptosis. PMID- 30279028 TI - Patient education during hospital admission due to exacerbation of chronic obstructive pulmonary disease: Effects on quality of life-Controlled and randomized experimental study. AB - : The objective of this study was to assess the effectiveness of an education program and telephone call follow-up at improving the health related quality of life (HRQL) of patients with chronic obstructive pulmonary disease (COPD). METHOD: Experimental, controlled, randomized, single blind study, masked data analysis. Duration of 2 years and 3 months. Patients hospitalised for exacerbation. The effectiveness was evaluated by calculating the absolute and relative change (%) of the St. George questionnaire scores (total and by dimensions) before and after the intervention program. Calculation of the effect of the group variable on the absolute and relative changes of the variables, Multiple Analysis of Variance (MANOVA). RESULTS: Completed study of 116 patients. Greater effects on their HRQL reported at admission (48.3 +/- SD 20.0 years). Patients in the intervention group improved significantly in their total SGRQ scores (-6.83) in absolute and relative terms and more significantly in their activity dimension (-16.05). CONCLUSIONS: The education program was effective at improving global HRQL, especially the activity dimension, in exacerbated COPD patients. PRACTICE IMPLICATIONS: This research contributes to clarifying the benefits and contents of education programs for patients with COPD; hospital admission is the suitable moment to contact these patients. PMID- 30279029 TI - Behaviour change techniques applied in interventions to enhance physical activity adherence in patients with chronic musculoskeletal conditions: A systematic review and meta-analysis. AB - OBJECTIVE: To identify Behaviour Change Techniques (BCTs) applied in interventions to enhance physical activity (PA) adherence in patients with chronic musculoskeletal conditions and to investigate the effectiveness of these interventions in increasing PA adherence. METHODS: A systematic search of seven databases was conducted. We included (cluster/quasi-) randomised controlled trials comparing behaviour change interventions to no/placebo/minimal interventions or usual care and involving at least a three-month post intervention follow-up. Methodological quality was assessed, study characteristics and BCTs were narratively summarised and a meta-analysis was conducted. RESULTS: Across 22 included studies, we coded 8-18 BCTs (mean = 11.2) in intervention and 0-12 (mean = 3.5) in control groups. Common BCTs were "graded tasks", "goal setting", "self-monitoring", "problem solving" and "feedback". Meta analyses of 17 studies revealed a small medium-term effect (3-6 months post intervention, standardised mean difference (SMD) = 0.20, 95% CI 0.08-0.33) and no long-term effect (7-12 months post-intervention, SMD = 0.13, 95% CI -0.02 to 0.28). Subgroup analysis yielded a higher effect (SMD = 0.29, 95% CI 0.19-0.40) for interventions using a greater number of BCTs. CONCLUSION: There is moderate quality evidence that interventions using BCTs are effective to enhance medium term physical activity adherence. PRACTICE IMPLICATION: While superiority of single BCTs was not shown, it is likely that using more BCTs results in better adherence.

AB - BACKGROUND/PURPOSE: Hepatic encephalopathy (HE), a major neuropsychiatric complication in advanced liver disease, is associated with poor prognosis. Sarcopenia, characterized by a decline in muscle mass, strength, and physical performance, is prevalent in liver cirrhosis. This study aims to explore whether sarcopenia is associated with HE in cirrhotic patients. METHODS: PubMed and EMBASE were searched for relevant cohort and case-control studies investigating the association between sarcopenia and HE up to July 2018. Data of patients' characteristics, definition of low muscle mass, and protocols of grading/diagnosing HE were retrieved. The primary outcome was estimated by a pooled odds ratio (OR) and its 95% confidence interval (CI), using a random effect model. RESULTS: The meta-analysis enrolled 6 studies, comprising 1795 patients. Sarcopenia was positively associated with the presence of HE (OR 2.74 with a 95% CI, 1.87 to 4.01). The association was less likely to be influenced by differences in research designs, focused study outcomes, muscle mass measurements, and protocols of grading/diagnosing HE. There was lack of evidence supporting higher serum ammonia levels in patients with sarcopenia. CONCLUSION: In patients with liver cirrhosis, there is a significant association between sarcopenia and HE. A greater number of prospective studies are necessary to clarify whether the association remains even after adjusting relevant confounders and to suggest effective prevention of HE in patients with coexisting sarcopenia.

AB - The purpose of this study was to assess the sonoelastographic features of four different muscles in patients with amyotrophic lateral sclerosis compared with healthy controls and to evaluate the relationship of these features to muscle strength and other ultrasonographic variables. Fourteen patients with amyotrophic lateral sclerosis and 20 controls were examined using strain sonoelastography scanning. The RGB channel fraction ratio was analyzed with ImageJ software (Version 1.48). Two main sonoelastographic patterns could be distinguished in the controls: a clear predominance of the blue channel (hard areas) and a more heterogeneous pattern with predominance of the green channel (intermediate stiffness). These patterns were also observed in patients, although a higher green channel score was observed in mildly impaired muscles, whereas a higher blue channel score was observed in the most severely impaired muscle. Sonoelastography may be a good complementary biomarker in the detection and monitoring of muscle changes in amyotrophic lateral sclerosis. PMID- 30279034 TI - Interventional pulmonology techniques in elderly patients with comorbidities. AB - Respiratory diseases are common cause of disability in the elderly and are often concomitant with other non-respiratory medical conditions. Interventional pulmonology includes advanced diagnostic and therapeutic techniques, successfully employed for benign and malignant pulmonary diseases with a good safety profile. A few studies are available on the efficacy and the safety of these procedures (both bronchoscopic and pleural techniques) in the elderly. Paucity of data in these patients may support reluctant clinicians. We carried out a non-systematic review aimed at describing the scientific literature on interventional pulmonology techniques in elderly patients with comorbidities. We summarized indications, performance characteristics, and safety profile of bronchoscopic techniques in the elderly, comparing outcomes between older and younger patients. We explored the role of age on anesthesia and sedation protocols during endoscopic procedures and assessed the influence of comorbidities on bronchoscopic outcomes. This review underlines that older age is not a barrier for implementing interventional pulmonology for diagnostic and therapeutic purposes. PMID- 30279032 TI - Integrated Histotripsy and Bubble Coalescence Transducer for Thrombolysis. AB - After the collapse of a cavitation bubble cloud, residual microbubbles can persist for up to seconds and function as weak cavitation nuclei for subsequent pulses in a phenomenon known as cavitation memory effect. In histotripsy, the cavitation memory effect can cause bubble clouds to repeatedly form at the same discrete set of sites. This effect limits the efficacy of histotripsy-based tissue fractionation. Our previous studies have indicated that low-amplitude bubble-coalescing (BC) ultrasound sequences interleaved with high-amplitude histotripsy pulses can coalesce the residual bubbles into one large bubble quickly. This reduces the cavitation memory effect and may increase treatment efficacy. Histotripsy has been investigated for thrombolysis by breaking up clots into debris smaller than red blood cells. However, this treatment has low efficacy for aged or retracted clots. In this study, we investigate the use of histotripsy with BC to improve the efficacy of treatment of retracted clots. An integrated histotripsy and bubble-coalescing (HBC) transducer system with specialized electronic driving system was built in-house. One high-amplitude (32 MPa), one-cycle histotripsy pulse followed by 36 low-amplitude (2.4 MPa), one cycle BC pulses formed one HBC sequence. Results indicate that HBC sequences successfully generated a flow channel through the retracted clots at scan speeds of 0.2-0.5 mm/s. The channel size created using the HBC sequence was 128% to 480% larger than that created using histotripsy alone. The clot debris particles generated during HBC treatments were within the tolerable range. These results illustrate the concept that BC improves the treatment efficacy of histotripsy thrombolysis for retracted clots.

PMID- 30279038 TI - Radiological Kinetics of Brain Metastases and Clinical Implications for Patients Treated With Stereotactic Radiosurgery. AB - AIMS: Select patients with brain metastases receive stereotactic radiosurgery (SRS) with the objective of improving survival and intracranial disease control. Brain metastases number and volume are prognostic factors used to inform patient selection. The aim of this study was to assess the rate of change of brain metastases size and number (growth kinetics) between the diagnostic and day of SRS magnetic resonance imaging (MRI) scans. MATERIALS AND METHODS: All patients treated with Gamma Knife SRS between October 2015 and April 2017 were included in this single-centre retrospective analysis. Brain metastases number and diameter were recorded at diagnosis and treatment. For patients with multiple brain metastases, the largest lesion was the index lesion. Distant intracranial control and overall survival were reported from the date of SRS. RESULTS: In total, 146 patients received 156 episodes of SRS. The median interval between diagnostic and SRS MRI was 20 days (range 1-68). Interval growth in the index lesion of at least 3 mm or the development of a new brain metastasis was noted in 60.2% of patients. This was associated with age less than 60 years (P = 0.001), Eastern Cooperative Oncology Group (ECOG) performance status 2 or above (P = 0.04), non-small cell lung carcinoma (NSCLC) (P = 0.03) or melanoma histologies (P = 0.05) and uncontrolled extracranial disease (P = 0.05). These patients were also more likely to develop distant intracranial recurrence (P = 0.046). Clinically significant growth was not associated with scan interval or differences in overall survival. The Kaplan-Meier estimate of probability of survival at 12 months was 59.3% (95% confidence interval 46.7-75.2%) for all patients. CONCLUSION: Intracranial progression between diagnosis and day of SRS is common. Risk factors are uncontrolled extracranial disease, poorer performance status, NSCLC or melanoma histologies and age less than 60 years. These patients would benefit from an MRI closer to treatment to inform patient selection and target delineation for SRS planning.

PMID- 30279042 TI - A methodology for customizing clinical tests for esophageal cancer based on patient preferences. AB - BACKGROUND: Clinical tests for diagnosis of any disease may be expensive, uncomfortable, time consuming and can have side effects e.g. barium swallow test for esophageal cancer. Although we can predict non-existence of esophageal cancer with near 100% certainty just using demographics, lifestyle, medical history information, and a few basic clinical tests but our objective is to devise a general methodology for customizing tests with user preferences to avoid expensive or uncomfortable tests. METHOD: We propose to use classifiers trained from electronic medical records (EMR) for selection of tests. The key idea is to design classifiers with 100% false normal rates, possibly at the cost of higher false abnormal. We find kernel logistic regression to be most suitable for the task. We propose an algorithm for finding the best probability threshold for kernel LR, based on test set accuracy tuning with help of a validation data set. Using the proposed algorithm, we describe schemes for selecting tests, which appear as features in the automatic classification algorithm, using preferences on costs and discomfort of the users i.e the proposed method is able to detect almost all true patients in the population even with user preferred clinical tests. RESULT: We test our methodology with EMRs collected for more than 3000 patients, as a part of project carried out by a reputed hospital in Mumbai, India. We found that kernel SVM and kernel LR with a polynomial kernel of degree 3, yields an accuracy of 99.18% and sensitivity 100% using only demographic, lifestyle, patient history, and basic clinical tests. We demonstrate our test selection algorithm using two case studies, one using cost of clinical tests, and other using "discomfort" values for clinical tests. We compute the test sets corresponding to the lowest false abnormals for each criterion described above, using exhaustive enumeration of 12 and 15 clinical tests respectively. The sets turn out to be different, substantiating our claim that one can customize test sets based on user preferences. PMID- 30279043 TI - Longitudinal trend of global artemisinin research in chemistry subject areas (1983-2017). AB - Artemisinin, the initial and main drug for malaria prevention and treatment internationally, was first extracted from the plant Artemisia annua L. by Chinese scientists in 1972. Research on artemisinin in chemistry subject areas shows a rapid growth since the 1980s. To evaluate the evolutionary trends and draw the knowledge map of artemisinin research, 1316 relevant publications are analysed based on bibliometrics. The global research status, emerging trends and future directions are also visualised and discussed. Furthermore, a historical overview of chemical synthesis on artemisinin is illustrated via timeline in terms of industrialisation. Overall, this study provides a novel method to visualise further information about artemisinin research and a comprehensive perspective to understand the longitudinal trend over the last 30 years. PMID- 30279044 TI - Synthesis and evaluation of 2-substituted 4(3H)-quinazolinone thioether derivatives as monoamine oxidase inhibitors. AB - In the present study, a series of fourteen 2-mercapto-4(3H)-quinazolinone derivatives was synthesised and evaluated as potential inhibitors of the human monoamine oxidase (MAO) enzymes. Quinazolinone is the oxidised form of quinazoline, and although this class has not yet been extensively explored as MAO inhibitors, it has been shown to possess a wide variety of biological activities. Among the quinazolinone derivatives investigated, seven compounds (IC50 < 1 uM) proved to be potent and specific MAO-B inhibitors, with the most potent inhibitor, 2-[(3-iodobenzyl)thio]quinazolin-4(3H)-one, exhibiting an IC50 value of 0.142 MUM. Further investigation showed that this inhibitor is a reversible and competitive inhibitor of MAO-B with a Ki value of 0.068 uM. None of the test compounds were MAO-A inhibitors. Analysis of the structure-activity relationships (SARs) for MAO-B inhibition shows that substitution on the C2 position of quinazolinone with a benzylthio moiety bearing a Cl, Br or I on the meta position yields the most potent inhibitors of the series. In contrast, substitution with the unsubstituted benzylthio moiety (IC50 = 3.03 uM) resulted in significantly weaker inhibition activity towards MAO-B. This study suggests that quinazolinones are promising leads for the development of selective MAO-B inhibitors which may be used for the treatment of neurodegenerative disorders such as Parkinson's disease.

PMID- 30279046 TI - Treatment outcomes for unresectable intrahepatic cholangiocarcinoma: Nationwide, population-based, cohort study based on propensity score matching with the Mahalanobis metric. AB - PURPOSE: No prospective randomized trials have been conducted to date to evaluate the efficacy of palliation of pain or jaundice without treatment, definitive concurrent chemoradiotherapy (CCRT), sequential chemotherapy and radiotherapy (CTRT), or chemotherapy (CT) alone for treating unresectable intrahepatic cholangiocarcinoma (ICC). We designed a nationwide, population-based, cohort study to determine the effects of different treatments on patients with unresectable ICC using propensity score matching (PSM) with the Mahalanobis metric. PATIENTS AND METHODS: We classified patients with unresectable ICC from the Taiwan Cancer Registry database into the following 4 treatment groups: group 1, definitive CCRT; group 2, sequential CTRT; group 3, no treatment (palliative therapy for relief of pain, pruritus, or jaundice); and group 4, CT alone. Confounding factors among the 4 treatment groups were minimized through propensity score matching (PSM). RESULTS: After PSM, the final cohort consisted of 844 patients (211 patients in each of the 4 groups). In both univariable and multivariable Cox regression analyses, adjusted hazard ratios (aHRs; 95% confidence interval [CI]) derived for groups 1 and 2 compared with group 4 were 0.65 (0.59-0.71) and 0.95 (0.83-1.48), respectively. Furthermore, an aHR (95% CI) of 2.25 (1.89-2.67) was derived for significant independent prognostic risk factors for poor overall survival for group 3 compared with group 4. CONCLUSIONS: Definitive CCRT is the optimal therapy for patients with unresectable ICC without distant metastasis. PMID- 30279048 TI - In reply to Keenan et al.

PMID- 30279047 TI - A cross sectional study in cognitive and neurobehavioral impairment in long-term nasopharyngeal cancer survivors treated with intensity-modulated radiotherapy. AB - PURPOSE/OBJECTIVES: To determine neurocognitive and neurobehavioral impairment in long-term nasopharyngeal cancer survivors (NPC) treated with intensity-modulated radiotherapy (IMRT). MATERIALS/METHODS: A cross-sectional cohort of NPC >=4 years (y) following IMRT was assessed. Objective cognitive function was measured using the Montreal Cognitive Assessment (MoCA) and patient-reported memory was assessed with the MDASI-HN problems remembering item. Patient and family ratings of patients' neurobehavioral symptoms of apathy, disinhibition and executive dysfunction were assessed with the Frontal Systems Behavior Scale (FrSBe). Other patient-reported symptoms (MDASI-HN), mood (HADS), and quality of life (FACT-H&N) were also collected. RESULTS: Among 102 participants: M:F = 66:36; median age 56y (32-77); median time since IMRT 7.5y (4.2-11.1). Impaired MoCA scores (<23) were observed in 33 (32%). Patient and family ratings of pre-illness neurobehavioral symptoms were in the normal range (total FrSBe T-scores 53.3 and 59.0 respectively). In contrast, post-treatment patient and family T-scores were clinically impaired (64.7, 71.3 respectively), with apathy, disinhibition and executive dysfunction post-treatment ratings all significantly worse than pre treatment (p < 0.001). Prevalence of clinically significant post-treatment disturbance was high by patient and family ratings (48%/66% apathy, 35%/53% disinhibition, 39%/56% executive dysfunction). Post-treatment neurobehavioral symptoms strongly correlated with lower quality of life (r = -0.62) and higher anxiety (r = 0.62) and depression scores (r = 0.67, all p < 0.001). Total MoCA scores did not correlate with RT dose. However, greater declines in apathy, disinhibition and executive dysfunction were associated with receiving >75 Gy to temporal lobes. CONCLUSION: NPC treated with IMRT had moderate to high rates of neurocognitive impairment and clinically significant apathy, disinhibition, and executive dysfunction. PMID- 30279050 TI - Age as a prognostic factor in relation to surgical evacuation of spontaneous supratentorial intracerebral haemorrhage. AB - AIM AND CLINICAL RATIONALE FOR THE STUDY: Spontaneous intracerebral haemorrhage (sICH) is an acute life-threatening injury and constitutes 10-15% of first-ever stroke cases. The Surgical Trials in Intracerebral Haematoma studies (STICH and STICH II) represent the two foremost studies in the field, however, with arguable shortcomings. To find more accurate criteria, we aimed to correlate the preoperative neurological and neuroimaging findings with the clinical outcome of operated patients. MATERIALS AND METHODS: In this retrospective study, sICH patients were recruited from the Central Denmark Region from 2010 to 2016. We evaluated the patients' medical records regarding preoperative Glasgow Coma Scale (GCS) 6 months and one year after surgery, focal neurological defects, thrombolytic treatment, pupil status, and haemorrhage localization visualized by neuroimaging. The patients' clinical outcome was assessed using the Glasgow Outcome Scale (GOS). RESULTS: Based on logistic multiple linear analysis, age, basal ganglia haemorrhage and mass effect had significant effect on the mortality rate. Besides, age, basal ganglia haemorrhage, intra ventricular haemorrhage and pupil difference had significant correlation with good outcome (GOS>3). CONCLUSIONS AND CLINICAL IMPLICATIONS: Neurosurgical treatment of the sICH patients is indicated only if age and potentially improved morbidity is carefully evaluated considering the STICH and this study; otherwise, we will just increase the health care burden with a number of extremely care-dependent patients. PMID- 30279049 TI - Quantitative radiomics: Validating image textural features for oncological PET in lung cancer. AB - BACKGROUND AND PURPOSE: Radiomics textural features derived from PET imaging are of broad and current interest due to recent evidence of their prognostic value during cancer management. An inherent assumption is the link between these imaging features and the underlying tumoral phenotypic spatial heterogeneity. The purpose of this work was to validate this assumption for tumors within the lung through a comparison of image based textural features and the ground truth activity distribution from which the images were created. A second purpose was to assess the level at which PET imaging introduces spatial texture not present in the associated ground truth activity distribution. MATERIALS AND METHODS: 25 lung lesions were created using an anthropomorphic phantom. Ten of the lesions had a spherical shape with a uniform activity distribution. The remaining 15 had an irregular shape with a heterogeneous activity distribution. PET images were created for each lesion using Monte Carlo simulation. 79 textural features related to the gray-level intensity histograms, co-occurrence matrices, neighborhood difference matrices, run length, and size zone matrices were derived from both the simulated PET images and ground truth activity maps. A comparison was made between the two datasets using statistical analysis. RESULTS: For homogenous lesions, features extracted from the PET images were largely irrelevant to the underlying uniform activity distribution. Additionally, the majority of these features assumed substantial values implying that an extensive amount of spatial texture had been introduced into the final imaging data. For heterogeneous lesions, complex trends were observed in the deviation between features extracted from PET images and those extracted from the ground truth activity maps. Moreover, the extent of both the deviation and the associated dynamic range was seen to be greatly feature-dependent. CONCLUSION: The use of image based textural features as a surrogate for tumoral phenotypic spatial heterogeneity could not be clearly validated. The association between the two is complex and a significant amount of uncertainty exist due to the introduction of incidental texture during image acquisition and reconstruction. PMID- 30279051 TI - TRIO gene segregation in a family with cerebellar ataxia. AB - AIM OF THE STUDY: To report a family with a novel TRIO gene mutation associated with phenotype of cerebellar ataxia. MATERIALS AND METHODS: Seven family members of Caribbean descent were recruited through our ataxia research protocol; of the family members, the mother and all 3 children were found to be affected with severe young-onset and rapidly progressive truncal and appendicular ataxia leading to early disability. Array comparative genomic hybridization, mitochondrial DNA analysis, and whole-exome sequencing were performed on 3 of the family members (mother and 2 daughters). RESULTS: While the maternal grandmother, great uncle and great aunt were unaffected, the mother and 3 children displayed cognitive dysfunction, severe ataxia, spasticity, and speech disturbances. Age of onset ranged between 3 and 17 years, with average current disease duration of 21 years. Whole-exome sequencing showed a variant p.A1214V in exon 22 of the TRIO gene in 3 of the family members. Array comparative genomic hybridization and mitochondrial DNA analysis were normal. The same variant was later discovered in all but one family member. CONCLUSIONS AND CLINICAL IMPLICATIONS: The TRIO p.A1214V variant is associated with cerebellar ataxia in the studied family; it was present in all affected and unaffected family members. Phenotype is severe and broad. Anticipation seems to be present (based on 2 affected generations). It is warranted to screen additional familial early-onset and rapidly progressive ataxia cases for this genotype. TRIO gene mutations may well represent a novel spinocerebellar ataxia subtype.

PMID- 30279053 TI - Rotational thromboelastometry (ROTEM(r))-guided diagnosis and management of amniotic fluid embolism. AB - Amniotic fluid embolism is a rare but often catastrophic emergency. The non specific clinical features and lack of diagnostic tests make it a diagnosis of exclusion. Point-of-care visco-elastometric testing is being increasingly used during obstetric haemorrhage. We present a case of amniotic fluid embolism, diagnosed and managed using rotational thromboelastography. During a precipitous labour, a 21-year-old multiparous woman became pale, distressed and disorientated. The fetus was delivered using forceps. Simultaneously maternal cardiac arrest occurred and advanced life support was commenced. As there was no obvious bleeding, pulmonary embolism was considered the most likely diagnosis and preparation was made to thrombolyse. During resuscitation, rotational thromboelastometry demonstrated haemostatic failure, supporting a diagnosis of amniotic fluid embolism. This reversed the decision to thrombolyse and focused the team on resuscitation and management of coagulopathy. Targeted blood products were given using a local protocol specific to obstetric bleeding. Return of cardiac output was achieved. The total measured blood loss was more than 3.6 L and transfusion was guided by point-of-care tests. Transfused blood products were six units of packed red blood cells, one pool of platelets, 12 units of fresh frozen plasma and 14 g of fibrinogen concentrate. This case demonstrates amniotic fluid embolism with haemostatic failure, without initial revealed blood loss. The high mortality of amniotic fluid embolism necessitates rapid diagnosis and aggressive management. Laboratory tests in this context are impractical in informing clinical decisions, showing the value of point-of-care testing in facilitating team work and timely administration of targeted blood products.

PMID- 30279054 TI - Women Veterans' Experiences with Department of Veterans Affairs Maternity Care: Current Successes and Targets for Improvement. AB - INTRODUCTION: Little is known about women veterans' experiences accessing and using Department of Veterans Affairs (VA) maternity care, which is nearly all purchased from non-VA providers. OBJECTIVE: To understand women veterans' experiences, preferences, and challenges using VA maternity care. METHODS: We conducted 27 semistructured interviews with women veterans who used VA maternity care during fiscal year 2016. To capture a wide variety of experiences, we randomly sampled veterans from urban and rural VA facilities with higher and lower volumes of VA paid deliveries. All interviews were recorded and transcribed verbatim. Transcripts were analyzed using inductive and deductive content analysis. RESULTS: Themes included experiences initiating prenatal care, obtaining prenatal and lactation classes, the role of maternity care coordinators, mental health care, and satisfaction with care. Women described challenges obtaining authorization for care and establishing care with non-VA providers. First-time mothers appreciated the availability of prenatal and lactation classes. VA maternity care coordinators helped women veterans to navigate the challenges related to VA maternity care, ranging from finding non-VA providers to billing. The majority of participants were engaged with mental health care before pregnancy and continued this care during pregnancy. Women's satisfaction with VA maternity care was impacted by access to supportive, knowledgeable providers; care coordinators; woman-centered labor and delivery experiences; and billing issues. CONCLUSIONS: Our findings provide a portrait of the current state of VA maternity care from the perspectives of women veterans and highlight areas, such as care coordination and woman-centered models for labor and delivery, that can improve satisfaction with care. PMID- 30279056 TI - Real-time fish stress visualization came true:A novel multi-stage color-switching wireless biosensor system. AB - An optical communication type biosensor system has been developed which can measure blood glucose concentration, which is a stress indicator of fish, in real time while fish swimming freely. However, this system is hard to make instant acknowledgment of fish stress level which has to contain an unavoidable delay in the judgment. In this research, we aimed to develop a novel stress visualization system which can quickly judge the levels for fish stress response instantly based on a color changeable LED while another LED was designed to send data. The present system is based on the principle of converting the output current value measured by the glucose biosensor corresponding to the stress response into a voltage value. Then, the color and stress switching points of the LED (Red, Yellow, Green) were decided based on the voltage value gained from the biosensor which mentioned above. Furthermore, we attempted to use our biosensor system to make real-time monitoring of fish stress in vivo. As results, the proposed sensor can make real-time measurement of glucose and shows a great response to those of actual fish sample in the range from 35.36 to 300 mg dl-1 (R = 0.9899). When the glucose concentration in the collected sample was switched to the concentration pre-sett, it was successful to switch the LED color according to the gained voltage value both in vitro and in vivo. Furthermore, when monitoring the stress responses of the fish in vivo, color switching corresponding to the sensor output current value was observed successfully. PMID- 30279057 TI - Fully printed one-step biosensing device using graphene/AuNPs composite. AB - Driven by the growing need of simple, cost efficient and flexible sensing systems, we have designed here a fully printed Reduced Graphene Oxide (rGO) based impedimetric sensor for one step sensing of DNA. The DNA sensor was fabricated by stamping of layered rGO and rGO/gold nanoparticles/single stranded DNA (rGO/AuNPs/ssDNA) composites over PET substrates using wax-printing technique. rGO works as an excellent working electrode, while the AuNPs create a suitable environment for ssDNA immobilization. Counter and reference electrodes were previously screen-printed on the plastic substrate, making thus a compact and highly integrated sensing platform. The change in electron transfer resistance after hybridization with a target ssDNA specific of Coxsackie B3 virus was monitored using electrochemical impedance spectroscopy (EIS), finding a linear response in the range of concentrations 0.01-20 uM. The novel, simple and straightforward one-step printing process for fabrication of a biosensing device developed keeps in mind the growing need of large scale device manufacturing. The successful proof-of-concept for the detection of DNA hybridization can be extended to other affinity biosensors, taking advantage of the integration of the bioreceptor on the sensor surface. Such ready-to-use biosensor would lead to a one-step electrochemical detection. PMID- 30279058 TI - Clinical Outcome of Ischemic Stroke in Old Patients Versus Oldest-Old. AB - BACKGROUND: It is unclear whether very old patients benefit from stroke unit. The aim of our work was to compare the clinical outcome of patients with ischemic stroke aged either 70 or 80 (G 1) versus oldest-old greater than or equal to 81 years (G 2). METHODS: Of 1187 patients admitted with stroke during 5 years in our stroke unit, we included 252 patients with independent functional status (modified Rankin scale, [mRS] <= 2) before the stroke. All patients underwent clinical examination, blood test, electrocardiography, brain imaging, and cerebrovascular ultrasound. Clinical outcome was assessed with the mRS and National Institutes of Health Stroke Scale (NIHSS) at discharge. We considered favorable outcome mRS 0-2 at discharge. RESULTS: Of 252 patients included, 55% were male, 150 (59.5%) patients belonged to G1 and 102 (40.5%) G2. We detected a significant increase of atrial fibrillation, bronchoaspiration, mortality, higher NIHSS at admission, and worse functional status at discharge in G2. No significant differences in other demographic, vascular risk factors, hospital stay, NIHSS at discharge or subtype of stroke were found. NIHSS at discharge was the only independent predictor of good functional status (odds ratio 0.4; 95% confidence interval, 0.3-0.6; P < .001). CONCLUSIONS: Oldest-old patients showed similar NIHSS at discharge than younger patients despite having higher neurological severity at admission. Our results support the hypothesis that oldest-old patients have good recovery potential, and should not be excluded from the stroke unit. The worse functional status detected at discharge in these patients could be attributed to others factors and not to neurological severity.

PMID- 30279060 TI - Defining delirium in idiopathic Parkinson's disease: A systematic review. AB - BACKGROUND: Parkinson's disease patients may be at increased risk of delirium and developing adverse outcomes, such as cognitive decline and increased mortality. Delirium is an acute state of confusion that has overlapping symptoms with Parkinson's dementia, making it difficult to identify. This study aimed to determine the diagnostic criteria, prevalence, management strategies and outcomes of delirium in Parkinson's through a systematic review of the literature. METHODS: Seven databases were used to identify all articles published before February 2017 comprising two key terms: "Parkinson's Disease" and "delirium". Data were extracted from studies meeting predefined inclusion criteria. RESULTS: Twenty articles were identified. Delirium prevalence in Parkinson's ranged from 0.3 to 60% depending on setting; a diagnosis of Parkinson's was associated with an increased risk of developing delirium. Delirium was identified/diagnosed using seven different criteria. Delirium may be associated with an increased length of hospital stay and worsening motor symptoms. We did not identify any studies examining the management of delirium in Parkinson's. DISCUSSION: This review highlights the paucity of well-designed, appropriately powered studies investigating delirium in Parkinson's. The results suggest that delirium is a significant issue in people with Parkinson's and that having delirium may be a risk factor for adverse outcomes, particularly in inpatient settings. Further prospective research is needed to accurately determine the prevalence of delirium in Parkinson's, its management strategies and outcomes, and to evaluate diagnostic criteria to differentiate between the overlapping symptoms of Parkinson's and delirium.

AB - Expiratory central airway collapse (ECAC) is a general term that incorporates tracheobronchomalacia (TBM) and excessive dynamic airway collapse (EDAC). TBM and EDAC are progressive, degenerative disorders of the tracheobronchial tree, causing airway collapse. Induction of general anesthesia can trigger intraoperative airway collapse in patients with these conditions. This crisis presents as the sudden inability to ventilate, which can lead to life-threatening hypoxemia and hypercapnia. This article reviews the definition, pathophysiology, diagnosis, and anesthetic implications of ECAC. PMID- 30279065 TI - Comparison of Coagulation Parameters in Arterial and Venous Blood in Cardiac Surgery Measured Using the Quantra System. AB - OBJECTIVE: Perioperative coagulation testing often is performed with arterial samples even though device reference ranges typically are established in venous samples. Although limited studies exist comparing coagulation parameters across sampling sites, viscoelastic testing devices have demonstrated some differences. The objective of this study was to compare coagulation parameters determined using the Quantra System for venous and arterial samples. DESIGN: Prospective, observational study. SETTING: Tertiary care university hospital. PARTICIPANTS: The study comprised 30 adult patients undergoing cardiac surgery. INTERVENTIONS: Paired arterial and venous samples were obtained at 2 of the following time points: baseline, during bypass, or after protamine reversal of heparin. Quantra measurements included Clot Time (CT), Heparinase Clot Time (CTH), Clot Time Ratio (CTR), Clot Stiffness (CS), and Fibrinogen (FCS) and Platelet (PCS) Contributions to clot stiffness. MEASUREMENTS AND MAIN RESULTS: The relationship and agreement between matched data pairs were established and statistical analysis was performed via paired t tests. CTR, CS, FCS, and PCS were unaffected by the sampling site, whereas CT and CTH demonstrated statistically significant differences between arterial and venous samples (p < 0.001). Arterial clot times were prolonged relative to the venous ones with a mean percent error of 14.2 % and 11.9 %, respectively. These results are in general agreement with those reported for other viscoelastic testing devices. CONCLUSIONS: This study demonstrates that Quantra clot stiffness-based parameters (CS, FCS, PCS) are unaffected by sampling site, whereas the clot time parameters (CT and CTH) show good correlation in the presence of a bias. CTR, a ratio of CT and CTH, also is unaffected. PMID- 30279066 TI - Expiratory Central Airway Collapse in Adults: Corrective Treatment (Part 2). AB - Corrective treatment of expiratory central airway collapse (ECAC) consists of placement of airway stents or tracheobronchoplasty (TBP). The indication for corrective treatment is severe central airway collapse (>90 %), and severe symptoms that cause decline in quality of life. Patients are selected to undergo a trial of tracheal "Y" stent placement. If symptoms improve (positive trial) they undergo a TBP, provided they are good surgical candidates. Patients who are considered poor surgical candidates because of the severity of comorbidities can be offered permanent stenting to palliate symptoms. The anesthetic management of airway stent placement and TBP is complex. This article reviews the medical management and corrective treatment of ECAC, anesthetic management of airway stent placement, and considerations during TBP.

AB - This paper discusses the ancient anthropological linkage of water and wine with sacred rituals after these substances have been the focus of nonlocal perturbation. The paper reports the changes produced can be both physical, as well as a subjective aesthetic reaction arising when individuals have a sensorial interaction with such treated substances. In making this argument the paper presents and discusses research done by others, as well as the author including reporting the results of a 12 part series of experiments in which groups of seven people tasted wine from one 750 ml bottle that had been decanted into two identical 375 ml carafes. The histories of the carafes were the same except that one, before the tasting, had been the focus of intentioned awareness by meditators, while the other was a control. Twelve sessions were conducted, 11 resulted in a majority preferring the treated wine, and one resulted in a tie. Using an exact binomial test, the p-value is (0.5)11=12048=0.00049. Therefore, with 95% confidence we can say that the probability that a majority would prefer the treated wine is at least 0.76. The paper in its conclusion discusses the implications of the totality of this research. PMID- 30279069 TI - Miracle Healings. PMID- 30279070 TI - Food Sources for Homeless Youth: An Evaluation of Food Availability at a Homeless Youth Drop-In Center. AB - OBJECTIVE: We utilized a validated food inventory questionnaire to assess the types and quality of food available at a homeless youth drop-in center. METHODS: Scores for 13 food categories were computed; higher scores indicated a greater availability of foods found in that category. A summative score was computed to assess the presence of obesogenic foods. RESULTS: Dry cereal, vegetables, and meat, were the most available foods; 83.3%, 60.9%, and 56.3% of food items in each category, respectively, were available. The food categories with least available items included candy and dairy: 26.6% and 25.4% of items in those categories, respectively. Mean obesogenic food availability score was 31 +/- 4.2 (range 23-34), out of a possible score of 71. CONCLUSIONS AND IMPLICATIONS: It is possible for a drop-in center to provide healthful foods to homeless youth. Further studies examining the extent to which drop-in centers contribute to the homeless youth food environment are warranted. PMID- 30279071 TI - Protein Language: Post-Translational Modifications Talking to Each Other. AB - Post-translational modifications (PTMs) are at the heart of many cellular signaling events. Apart from a single regulatory PTM, there are also PTMs that function in orchestrated manners. Such PTM crosstalk usually serves as a fine tuning mechanism to adjust cellular responses to the slightest changes in the environment. While PTM crosstalk has been studied in depth in various species; in plants, this field is just emerging. In this review, we discuss recent studies on crosstalk between three of the most common protein PTMs in plant cells, being phosphorylation, ubiquitination, and sumoylation, and we highlight the diverse underlying mechanisms as well as signaling outputs of such crosstalk.

AB - Geminivirus infection results in systemic symptoms in plants, but the mechanism by which the virus affects cell-to-cell signalling involved in development and resistance remains unclear. Based on recent evidence, we suggest a potential mechanism that geminivirus C4 proteins interfere with intercellular signals by interacting with receptor-like kinases on the plasma membrane. PMID- 30279073 TI - The evaluation of forensic characteristics and the phylogenetic analysis of the Ong Be language-speaking population based on Y-STR. AB - The Ong Be language, an important branch of the Tai-Kadai language family, is one of the most distinctive languages on Hainan Island. Ong Be language speakers, who have lived in the Lingao district of Hainan Island for generations, were classified as Han Chinese in the early days of the establishment of the People's Republic of China but have distinct differences from the Han Chinese in language, lifestyle, customs and values and particularly in appearances and features. Currently, Y-chromosomal short tandem repeat (STR) haplotypes have been widely used in genetic applications, such as human forensics, historical investigations and genealogical research. In this study, 487 unrelated male individuals residing in the Lingao district volunteered, and their Y-STR haplotypes were investigated using the Yfiler and Yfiler Plus with 17 and 27 Y-STR loci, respectively. Furthermore, we combined our population data on the Lingao people with existing datasets from Asian nations (East, South and Southeast Asia) to explore the genetic variance and relationships with Han Chinese from different administrative regions in Northern and Southern China and Chinese ethnic minorities officially recognized by the PRC. Population comparisons demonstrated that the Lingao people had distant relationships with Asian nations at the national level and had relatively close genetic and linguistic relationships with Hainan Li and Guizhou Gelao, both of whom belong to the Tai-Kadai language family. The present results increase our understanding of the genetic relationships between the Lingao people and other groups, and further research in genetics and other areas is still needed to trace the origin of the Lingao people. PMID- 30279074 TI - Relationship between somatostatin and interleukin-6: A cross-sectional study in patients with acute pancreatitis. AB - OBJECTIVES: The aim of the analysis is to determine dynamic changes in somatostatin (SS) and interleukin-6 (IL-6) concentrations during in acute pancreatitis (AP). METHODS: The influence of tobacco smoking on IL-6 and SS levels in the serum of non-smoking (n = 10) and smoking (n = 27) patients with diagnosed AP and control group: non-smoking (n = 44), smoking (n = 42) and passive smoking (n = 29) healthy persons was proved. The concentration of IL-6 and SS was determined by means of ELISA. Differences between the groups analyzed were tested using the U Mann Whitney test. The Spearman rank correlation analysis was used to evaluate the correlations. RESULTS: The concentrations of IL-6 and SS were significantly higher in smoking patients with AP and healthy persons when compared with non-smoking population on every day (1 day: p = 0.0002, p = 0.015; 3 day: p = 0.005, p = 0.001 and 7 day: p = 0.025, p = 0.038). Dynamic changes in concentrations of IL-6 and SS in the serum of patients with AP were demonstrated in the ensuing days of the disease. In case of non-smoking and smoking patients, significant positive correlations between IL-6 and SS was observed. CONCLUSIONS: These findings suggest that some of the antiinflammatory effects of SS against acute pancreatitis may be mediated by reducing the local proinflammatory cytokine secretion in the pancreas. PMID- 30279075 TI - Phenotyping and long-term follow up of patients with hyper IgE syndrome. AB - INTRODUCTION AND OBJECTIVES: Long-term follow up of patients with hyper IgE syndrome (HIES), as a primary immunodeficiency disorder, has been poorly investigated. This study describes common clinical and immunological features of patients with HIES in the last 10 years in Shiraz University of Medical Sciences, Shiraz, Iran. METHODS AND PATIENTS: In this cross-sectional study, the symptoms and medical records of 18 patients, who were diagnosed with HIES, were observed. Genetic and immunologic study was also performed. RESULTS: Eighteen patients with the mean age of 13 years old were investigated. Ten patients were detected to have mutations in DOCK8 gene and autosomal recessive HIES (AR-HIES); and four patients were found with STAT3 mutation and autosomal dominant HIES (AD-HIES). So, 14 patients with known genetic results were considered for further data analysis. Food allergy, eczema, viral and skin infections were the major complications of AR-HIES patients. The major clinical complications of AD-HIES patients were pneumonia, skin infections and eczema. Food allergy and viral infection were significantly higher in DOCK8 deficient patients. The most common causes of hospitalization in both AR-HIES and AD-HIES patients were pneumonia, skin infections and sepsis. The most common cause of death was found to be sepsis. CONCLUSIONS: AD-HIES and AR-HIES cannot be differentiated only based on the clinical presentations. Genetic features are also necessary for better diagnosis. This study, summarizing the clinical, immunological and genetic information of the patients with AD-HIES and AR-HIES, may open a way for better diagnosis and management of HIES.

AB - BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has serious complications, such as leaks, reflux, stenosis, and kinks, which are also consequences of shortcomings in the LSG technique. OBJECTIVES: We evaluated the feasibility and weight loss of a novel bariatric procedure, using the greater curvature as the gastric pouch for sleeve gastrectomy (SG) in dogs. SETTING: Animal house in Faculty of Medicine, Cairo University. METHODS: Five 20- to 25-kg stray mongrel male dogs were subjected to open SG using the greater curve as the gastric pouch (GCSG group). The weight was monitored at day of surgery and at postoperative weeks 2, 4, 6, and 8; weight progression was compared with a sham and a standard SG group. By the end of the follow-up period autopsy was done. RESULTS: The mean operative time in GCSG group was 39.6 +/- 3.97 minutes. At the end of the study, dogs in the sham group had gained 8% of their preoperative weight, while the GCSG and standard SG groups lost 24.7% and 25% of their preoperative weight, respectively. At autopsy, the gastric sleeve in the GCSG group showed excellent healing with no stenotic areas, kinks, or mucosal ulcerations. CONCLUSION: Greater curvature SG is technically feasible in a canine model. Larger studies with longer follow-up period will be needed to assess weight progression and resolution of the metabolic co-morbidities.

AB - Anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis is a type of immune mediated encephalitis, which is a new category of treatment-responsive paraneoplastic encephalitis. In patients with this disease, electroencephalography (EEG) shows non-specific findings, but recently, a unique EEG pattern, named the extreme delta brush, was detected in 40% of adult patients and was suggested to be specific to this type of encephalitis. Here, we describe a two-year-old boy with anti-NMDAR encephalitis, who presented with speech arrest and disturbances of gait and cognition several weeks after developing febrile convulsions. In the early stages of the disease, EEG showed 14-16 Hz, continuous, fast waves characterized by a high amplitude (200-500 AuV), very diffuse spreading, and a sharp morphology, during light sleep only, which was compatible with extreme spindles. As the patient's symptoms worsened, this finding was replaced by rhythmic, diffuse, high-voltage, slow waves. Immediately after immunomodulatory therapies, including intravenous methylprednisolone and immunoglobulin, his clinical manifestations and EEG abnormalities appeared to improve. We propose that although the extreme spindle is a non-specific finding of this type of encephalitis, early EEG monitoring might be necessary to detect not only the extreme delta brush pattern, but also non-specific findings, including extreme spindles, which would aid early diagnosis and treatment.

PMID- 30279083 TI - Electroencephalography and brain magnetic resonance imaging in asphyxia comparing cooled and non-cooled infants. AB - OBJECTIVE: The aim was to establish any differences in the predictive value of EEG and MRI for outcome in infants treated and not-treated with therapeutic hypothermia (HT) for perinatal asphyxia. We hypothesize that they are equally predictive and that combining both has the highest predictive value. STUDY DESIGN: We retrospectively compared data of infants with hypoxic-ischemic encephalopathy (HIE) who received HT (n = 45) between September 2009 and December 2013 with those of infants with HIE born between January 2004 and August 2009, before HT was available (NT, n = 37). All received conventional and/or amplitude integrated EEG during the first days and early MRI (day 4-5). Associations of EEG, MRI and severe neurodevelopmental outcome (death or Bayley's -2SD below mean), were tested with a multivariable logistic regression analysis, corrected for HT. RESULTS: Forty-eight hours' EEG background pattern had a PPV of 92% and a NPV of 81% in HT, versus 100% and 58% in NT. MRI had a PPV of 71% and a NPV of 93% in HT, versus 82% and 75% in NT. The adjusted OR for adverse outcome was 0.013 (95% CI 0.002-0.154, p < 0.001) for EEG background normalization within 48 h and 32.19 (95% CI 4.84-214.25, p < 0.001) for abnormal MRI. CONCLUSION: The predictive value of EEG and MRI is equal in cooled and non-cooled infants with HIE. Our data show a higher predictive value (death and severe outcome) for EEG compared to MRI. In HIE, persistent abnormal EEG background pattern until 48 h, combined with abnormal early MRI is strongly predictive for poor neurodevelopment. PMID- 30279084 TI - Diagnosis of tuberous sclerosis complex in the fetus. AB - Tuberous sclerosis complex is a dominantly inherited genetic disorder of striking clinical variability. It is caused by mutations in either TSC1 or TSC2 gene, which regulate cell growth and proliferation by inhibition of mTORC1 signaling. TS is characterized by the development of benign tumors in many tissues and organs and its neurological manifestations include epilepsy, autism, cognitive and behavioral dysfunction, and giant cell tumors. With mechanism-based mTOR inhibitors therapy now available for many of its manifestations, early diagnosis of TSC is very important in order to offer appropriate care, long-term surveillance and parental counseling. Fetal ultrasound and MRI imaging techniques have evolved and may capture even earlier the following TSC-associated lesions: cardiac rhabdomyomas, subependymal nodules, cortical tubers and renal cysts. Often these represent an incidental finding during a routine ultrasound. Furthermore, in the past decades prenatal molecular diagnosis of TSC has emerged as an important option for families with a known affected member; however, the existing evidence with regards to the clinical characteristics and long-term outcome of babies diagnosed prenatally with TSC is yet limited and the path that follows early TSC detection merits further research. PMID- 30279085 TI - Increased cerebral microbleeds and cortical superficial siderosis in pediatric patients with Down syndrome. AB - BACKGROUND: Patients with Down syndrome carry a third copy of the amyloid precursor protein gene, which is localized on chromosome 21. Consequently, these patients are prone to develop early-onset Alzheimer disease and cerebral amyloid angiopathy. Post-mortem studies suggest increased amyloid deposition to be already detectable in children with Down syndrome. The aim of our study was to evaluate if amyloid-related changes in pediatric Down syndrome patients can be detected in vivo using MRI biomarkers of cerebral microbleeds and cortical superficial siderosis. MATERIALS AND METHODS: This retrospective study included 12 patients with Down syndrome (mean age = 5.0 years) and 12 age-matched control subjects (mean age = 4.8 years). Frequency and location of microbleeds and siderosis were assessed on blood-sensitive MRI sequences in a consensus reading by two radiologists applying a modified Microbleed Anatomical Rating Scale. RESULTS: Down syndrome patients showed a significantly higher mean microbleeds count and likelihood of siderosis than age-matched controls. Across groups, the highest microbleeds count was found in lobar regions (gray and white matter of frontal, parietal, temporal, and occipital lobes, and the insula), while fewer microbleeds were located in subcortical and infratentorial regions. The number of microbleeds increased over time in all three Down syndrome patients with a follow up exam. CONCLUSION: In vivo MRI biomarkers can support the diagnosis of early onset cerebral amyloid angiopathy, which might already be present in pediatric Down syndrome patients. This might contribute to clinical decision-making and potentially to the development of therapeutic and prophylactic approaches, as cerebral amyloid angiopathy increases the risk for intracranial hemorrhage and may be associated with increased risk of developing Alzheimer disease. PMID- 30279086 TI - Effect of phacoemulsification incision size on incision repair and remodeling: Optical coherence tomography assessment. AB - PURPOSE: To characterize the effect of incision size on corneal incision repair and remodeling over 3 months after cataract surgery. SETTING: Department of Ophthalmology, Auckland District Health Board, Auckland, New Zealand. DESIGN: Prospective case series. METHODS: Eyes having routine cataract surgery were randomized to receive 2.20 mm or 2.85 mm uniplanar clear corneal incisions. Anterior segment optical coherence tomography of incision thickness, length, width, gaping, and angle and specular microscopy of endothelial cell density (ECD), polymegathism, and pleomorphism were completed at baseline and 1, 7, 30, and 90 days postoperatively. RESULTS: Each incision group comprised 50 eyes (50 patients). Ninety-nine patients (99%) attended all assessments. The Descemet membrane detachment rate was greater than 50% with 2.20 mm incisions (P = .01). Patients with Descemet membrane detachments had increased endothelial wound gaping, slower visual recovery, and increased corneal thickness at the incision site at all visits (phi = 0.54, P < .01). The 2.20 mm group had greater polymegathism despite no difference in the mean phacoemulsification energy between groups (2.20 mm: 32.3% +/- 6.2% [SD]; 2.85 mm: 30.8% +/- 6.5%) (P = .02). Ninety days postoperatively, the 2.20 mm group had a lower mean ECD (2195 +/- 360 cells/mm2) than the 2.85 mm group (2397 +/- 335 cells/mm2) (P = .01). Final visual acuity, gaping, and angles were not significantly different between the groups. CONCLUSIONS: The 2.20 mm wide corneal incisions were more prone to trauma than 2.85 mm incisions during routine cataract surgery. Corneal incisions with signs of trauma were associated with prolonged visual recovery and slower healing postoperatively. PMID- 30279087 TI - Serial intraocular lens opacifications of different designs from the same manufacturer: Clinical and light microscopic results of 71 explant cases. AB - PURPOSE: To report clinical findings and light microscopic results of 71 opacified hydrophilic acrylic intraocular lenses (IOLs). SETTING: Vivantes Klinikum Neukoelln, Ophthalmology Department, Berlin, Germany. DESIGN: Retrospective case series. METHODS: Sixty-three patients (71 eyes) were referred to the clinic because of vision-impairing IOL opacification between December 2012 and September 2016 after routine cataract surgery elsewhere. The explanted IOLs were analyzed with light microscopy at the John A. Moran Eye Center (University of Utah, Salt Lake City, Utah, USA). Medical records were reviewed for visual acuity, comorbidities, and complications. Clinical follow up was 6 months. RESULTS: Seventy-one opacified 1-piece or 3-piece hydrophilic acrylic IOLs (Lentis) of different designs from 2009 to 2012 (LS-502-1, LS-402-1Y, LS 312-1Y, LS-313-1Y, L-402, L-312) were found. Morphological findings were surface, subsurface, or deep calcifications of the IOL material. Explantation was performed 4 years +/- 1.2 (SD) after initial phacoemulsification. The mean patient age was 78.6 +/- 8.2 years. Ocular and systemic comorbidities were found without statistical correlation: the most frequent were diabetes, uveitis, and glaucoma. The preoperative mean corrected distance visual acuity changed from 0.63 +/- 0.47 logarithm of the minimum angle of resolution (logMAR) to 0.20 +/- 0.28 logMAR postoperatively (P < .001). CONCLUSIONS: Different designs of IOLs by the same manufacturer, implanted between 2009 and 2012, developed late calcification with significant visual loss after routine cataract surgery. No medical, surgical, or ophthalmologic trigger could be determined. A manufacture issue might be the reason for the opacification. PMID- 30279088 TI - Agreement between lens thickness measurements by ultrasound immersion biometry and optical biometry. AB - PURPOSE: To compare lens thickness measurements provided by immersion ultrasound (US) biometry and optical biometry. SETTING: IRCCS-Fondazione Bietti, Rome, Italy. DESIGN: Evaluation of diagnostic technology. METHODS: Immersion US biometry and optical biometry were performed in a consecutive series of eyes having cataract surgery. Three optical biometers (OA-2000, Aladdin, and Galilei G6) were used. To assess how the differences in lens thickness measurements influenced intraocular lens (IOL) power calculation, the lens thickness values were entered into the Olsen formula. RESULTS: Eighty-eight eyes were analyzed. Ultrasound immersion biometry yielded significantly higher lens thickness values than all of the optical biometers (P < .0001). The mean difference ranged between 0.29 mm and 0.43 mm. Although the differences between the 3 optical biometers were smaller, they were still statistically significant (P < .001). With respect to the immersion US biometry, lens thickness measurements using the optical biometric measurements would have resulted in the selection of a lower IOL power in between 43.2% and 62.5% of eyes, depending on the optical biometer. Comparison of the measurements of the 3 optical biometers showed that a different IOL power would have been selected in between 9.1% and 19.3% of eyes. CONCLUSIONS: Lens thickness measurements by immersion US biometry and optical biometry cannot be considered interchangeable. Minor, but still significant, differences between the 3 optical biometers tested were also found.

PMID- 30279091 TI - Communication-based interventions for increasing influenza vaccination rates among Aboriginal children: A randomised controlled trial. AB - BACKGROUND: In Australia, the influenza vaccine is funded for Aboriginal and Torres Strait Islander (hereafter referred to as Aboriginal) children aged 6 months to <5 years old. In Victoria, only 2% of Aboriginal children are vaccinated against influenza. OBJECTIVE: To evaluate whether sending a letter or sending a pamphlet directly to parents/guardians would improve influenza vaccine uptake amongst Aboriginal identified children. DESIGN: The study involved a multi arm, parallel, randomised controlled trial with two intervention groups and one control group. PARTICIPANTS & SETTING: Participants included parents or guardians of Victorian children (aged 6 months to <5 years) who identified as Aboriginal. Households (n = 5534) were randomised (using a random number generator) to receive either a personalised letter (n = 1845), a pamphlet (n = 1845), or no direct communication (control) (n = 1844). The letter and the pamphlet were designed using the INSPIRE framework - a set of behaviour change techniques for action-oriented communication. MAIN OUTCOME MEASURE: The proportion of households where all eligible children received the influenza vaccine between 2 May 2017 and 1 September 2017. RESULTS: The control group's vaccination rate was 4.4%, higher than previous years. The pamphlet group achieved a similar vaccination rate (4.5%). The letter group's vaccination rate of 5.9% was significantly higher than the control group [chi2 (1, n = 3689) = 4.33, p = .037]. CONCLUSIONS: Sending a personalised letter directly to parents/guardians was an effective strategy for increasing influenza vaccination among Aboriginal children. The ineffectiveness of the pamphlet may be due to the lack of personalisation and the authority associated with the letter. Additional research is required to understand participant responses to the material. TRIAL REGISTRATION: This research was retrospectively registered with the Australian New Zealand Clinical Trials Registry (ANZCTR) on 13 September 2017 (ACTRN12617001315303). PMID- 30279090 TI - Memory inflation following adenoviral vaccination depends on IL-21. AB - Cytomegalovirus (CMV) and non-replicating adenoviral vectors can induce expanded, sustained effector-memory CD8+ T-cell responses, termed "memory inflation". During murine CMV (MCMV) infection, CD4+ Tcells maintain inflationary virus specific CD8+ T-cell responses via IL-2 but not IL-21. Adenovirus vector vaccination can induce phenotypically, functionally and transcriptionally similar inflationary responses, but it is not known how IL-21 influences the inflating memory response to adenoviral vaccination. Here, we show that IL-21 is an absolute requirement for induction and maintenance of vaccine-derived inflationary CD8+ T-cell responses. These data indicate that the induction pathway of inflationary Ad-LacZ T-cells is distinct from inflationary MCMV specific T-cells and is highly dependent on IL-21. Our observations highlight a fundamental difference in the mechanism by which adenovirus vectors and MCMV drive inflationary T-cell responses. PMID- 30279092 TI - Recognition and killing of Brugia malayi microfilariae by human immune cells is dependent on the parasite sample and is not altered by ivermectin treatment. AB - Mass administration of macrocyclic lactones targets the transmission of the causative agents of lymphatic filariasis to their insect vectors by rapidly clearing microfilariae (Mf) from the circulation. It has been proposed that the anti-filarial action of these drugs may be mediated through the host immune system. We recently developed an in vitro assay for monitoring the attachment to and killing of B. malayi Mf by human neutrophils (PMNs) and monocytes (PBMCs), however, the levels of both cell to worm attachment and leukocyte mediated Mf killing varied greatly between individual experiments. To determine whether differences in an individual's immune cells or the Mf themselves might account for the variability in survival, PMNs and PBMCs were isolated from 12 donors every week for 4 weeks and the cells used for survival assays with a different batch of Mf, thereby keeping donors constant but varying the Mf sample. Results from these experiments indicate that, overall, killing is Mf-rather than donor dependent. To assess whether ivermectin (IVM) or diethylcarbamazine (DEC) increase killing, Mf were incubated either alone or with immune cells in the presence of IVM or DEC. Neither drug induced a significant difference in the survival of Mf whether cultured with or without cells, with the exception of DEC at 2 h post incubation. In addition, human PBMCs and PMNs were incubated with IVM or DEC for 1 h or 16 h prior to RNA extraction and Illumina sequencing. Although donor-to-donor variation may mask subtle differences in gene expression, principle component analysis of the RNASeq data indicates that there is no significant change in the expression of any genes from the treated cells versus controls. Together these data suggest that IVM and DEC have little direct effect on immune cells involved in the rapid clearance of Mf from the circulation. PMID- 30279093 TI - Tel1 and Rif2 oppositely regulate telomere protection at uncapped telomeres in Saccharomyces cerevisiae. AB - It has been well documented that Tel1 positively regulates telomere-end resection by promoting Mre11-Rad50-Xrs2 (MRX) activity, while Rif2 negatively regulates telomere-end resection by inhibiting MRX activity. At uncapped telomeres, whether Tel1 or Rif2 plays any role remains largely unknown. In this work, we examined the roles of Tel1 and Rif2 at uncapped telomeres in yku70Delta and/or cdc13-1 mutant cells cultured at non-permissive temperature. We found that deletion of TEL1 exacerbates the temperature sensitivity of both yku70Delta and cdc13-1 cells. Further epistasis analysis indicated that MRX and Tel1 function in the same pathway in telomere protection. Consistently, TEL1 deletion increases accumulation of Exo1-dependent telomeric single-stranded DNA (ssDNA) at uncapped telomeres, which stimulates checkpoint-dependent cell cycle arrest. Moreover, TEL1 deletion in yku70Delta cells facilitates Rad51-dependent Y' recombination. In contrast, RIF2 deletion in yku70Delta cells decreases the accumulation of telomeric ssDNA after 8 h of incubation at the non-permissive temperature of 37 degrees C and suppresses the temperature sensitivity of yku70Delta cells, likely due to the increase of Mre11 association at telomeres. Collectively, our findings indicate that Tel1 and Rif2 regulate telomere protection at uncapped telomeres via their roles in balancing MRX activity in telomere resection. PMID- 30279094 TI - Characterization of a novel regulatory pathway for mannitol metabolism and its coordination with biofilm formation in Mycobacterium smegmatis. AB - Biofilm formation has been implicated to be tightly regulated in bacteria. Mycobacterial species possess a unique cell-wall structure; however, the underlying regulation mechanism for their biofilm formation remains largely unclear. In this study, we characterized a hypothetical mannitol metabolism and transportation gene cluster (Ms5571-Ms5576), designated as mmt operon, whose expression significantly contributes to the biofilm formation in Mycobacterium smegmatis. We showed that in the operon the Ms5575 gene encodes a GntR-like transcriptional repressor and the Ms5576 gene encodes a mannitol 2-dehydrogenase which can produce D-mannitol from D-mannose. Strikingly, the D-mannitol molecule can derepress the negative regulation of Ms5575 on the mmt operon to stimulate the operon's expression. Consistently, addition of D-mannitol into the medium can obviously induce mycobacterial biofilm formation. Furthermore, we found that Ms0179 positively regulates the mmt operon through its downstream regulator Ms0180. Ms0180 directly binds the mmt operon to positively regulate its expression. Both Ms0179 and Ms0180 significantly affect the mycobacterial biofilm formation. Taken together, we explored a regulatory pathway for the mannitol metabolism and its coordination with the biofilm formation in M. smegmatis. This finding provides novel insights into the unique mechanism of biofilm formation regulation in mycobacteria. PMID- 30279096 TI - Neuronatin deletion causes postnatal growth restriction and adult obesity in 129S2/Sv mice. AB - OBJECTIVE: Imprinted genes are crucial for the growth and development of fetal and juvenile mammals. Altered imprinted gene dosage causes a variety of human disorders, with growth and development during these crucial early stages strongly linked with future metabolic health in adulthood. Neuronatin (Nnat) is a paternally expressed imprinted gene found in neuroendocrine systems and white adipose tissue and is regulated by the diet and leptin. Neuronatin expression is downregulated in obese children and has been associated with stochastic obesity in C57BL/6 mice. However, our recent studies of Nnat null mice on this genetic background failed to display any body weight or feeding phenotypes but revealed a defect in glucose-stimulated insulin secretion due to the ability of neuronatin to potentiate signal peptidase cleavage of preproinsulin. Nnat deficiency in beta cells therefore caused a lack of appropriate storage and secretion of mature insulin. METHODS: To further explore the potential role of Nnat in the regulation of body weight and adiposity, we studied classical imprinting-related phenotypes such as placental, fetal, and postnatal growth trajectory patterns that may impact upon subsequent adult metabolic phenotypes. RESULTS: Here we find that, in contrast to the lack of any body weight or feeding phenotypes on the C57BL/6J background, deletion of Nnat in mice on 129S2/Sv background causes a postnatal growth restriction with reduced adipose tissue accumulation, followed by catch up growth after weaning. This was in the absence of any effect on fetal growth or placental development. In adult 129S2/Sv mice, Nnat deletion was associated with hyperphagia, reduced energy expenditure, and partial leptin resistance. Lack of neuronatin also potentiated obesity caused by either aging or high fat diet feeding. CONCLUSIONS: The imprinted gene Nnat plays a key role in postnatal growth, adult energy homeostasis, and the pathogenesis of obesity via catch up growth effects, but this role is dependent upon genetic background. PMID- 30279097 TI - On the observation of lubrication mechanisms within hip joint replacements. Part II: Hard-on-hard bearing pairs. AB - The present paper represents Part II of the extensive study focused on the lubrication of hip joint replacements. The main goal is to assess the fundamentals of lubrication considering both hard-on-soft (Part I) and hard-on hard (Part II) bearing pairs. In addition, the effect of individual constituents contained in the model fluid is clarified. For this purpose, multiple model fluids of various composition were employed. In this part of the study, metal-on glass contact representing hard bearing pairs was observed in situ using pendulum hip joint simulator in combination with thin film colorimetric interferometry method. The designed test consists of initial static loading/unloading phase for the determination of adsorption of molecules on rubbing surfaces. This period is followed by swinging of the pendulum and latest static part under constant load. Three groups of measurements were carried out while fourteen different lubricants were tested. Initially, the experiments were performed with albumin-based model fluid. In that case a substantial positive effect of hyaluronic acid was identified. In contrast, the fluids with gamma-globulin as a base constituent showed improved lubrication conditions when phospholipids were added to the solution. Finally, considering the complex fluid, a combined effect of hyaluronic acid and phospholipids caused a better endurance of the lubricant film. The latest part of the paper aims on the comparison of film formation considering hard and soft pairs, highlighting some clear differences. In general, hard pairs exhibit clear decreasing tendency of the film during swinging motion while opposite behaviour was observed for soft pairs. PMID- 30279098 TI - Immunosuppressive burden and risk factors of infection in primary childhood nephrotic syndrome. AB - INTRODUCTION: Patients with primary childhood nephrotic syndrome (PCNS) develop alterations in their cellular and humoral immunity that predisposes them to the development of infection, and lead them to have frequent relapses. Also, infection could be significantly enhanced by immunosuppressive agents. This study aims to estimate the immunosuppressive burden, rate of infection and identify possible risk factors in PCNS requiring hospitalization. METHODOLOGY: A cross sectional study of hospitalized children<=14years of age diagnosed with PCNS in King Abdul-Aziz Medical City, Riyadh from January 2003 to December 2013. RESULT: Out of 111 patients admitted with PCNS, 84 (76%) had both minor and major types of infection. Upper respiratory tract infection (URTI) was the most predominant type (n=44, 52%). Among the major types of infection, urinary tract infection (UTI) was the most common infection (n=21, 25%) followed by pneumonia (n=17, 20%) then cellulitis (n=6, 6%). Infection in children who received a higher annual cumulative dose of steroids (CDS) strikingly had a higher rate of infection in comparison to those who received lower CDS (p<0.01). Moreover, those who received primary and secondary immunosuppressant's had 100% infection rate. CONCLUSION: About half of infection encountered by PCNS patients were URTI followed by UTI and pneumonia. Higher annual CDS, combination of primary and secondary immunosuppressants were the highest independent risk factors for infection. Among the infection, URTI was considered as the predominant entity whereas among the major infection, UTI was predominant followed by pneumonia then cellulitis. PMID- 30279095 TI - Obstructive sleep apnea and the metabolic syndrome: The road to clinically meaningful phenotyping, improved prognosis, and personalized treatment. AB - Obstructive sleep apnea (OSA) is an increasingly prevalent sleep disorder characterized by upper airway obstruction during sleep, resulting in breathing pauses, intermittent hypoxia, and fragmented sleep. In parallel, the constellation of adverse health outcomes associated with prolonged obesity, such as insulin resistance, elevated blood pressure, triglycerides, and reduced high density lipoprotein cholesterol - termed metabolic syndrome -raises the risk of cardiovascular morbidity and mortality, type 2 diabetes, and all-cause mortality. Affecting 35-40% of U.S. adults, risk factors for metabolic syndrome, including obesity, middle age, sedentary behavior, and genetics, share considerable overlap with those for OSA. Thus, it has been difficult to disentangle cause, effect, and whether certain treatments, such as CPAP, can improve these outcomes. In this paper, we provide an update to our 2005 review which explored the association between OSA and metabolic syndrome, highlighting visceral obesity as the common etiological factor of both conditions. This update includes (a) recent data on physiological and biochemical mechanisms, (b) new data in nonobese men and women as well as children and adolescents, (c) insight from the latest treatment studies, (d) the role of aging in understanding clinically-meaningful phenotypes of the disorder, and (e) the potential diagnostic/prognostic utility of biomarkers in identifying OSA patients with the strongest cardiometabolic risk. PMID- 30279099 TI - Treatment of peristomal hemorrhage: A review of outcomes and comparison of two minimally invasive techniques. AB - PURPOSE: The purpose of this study was to review and compare outcomes between percutaneous sclerotherapy and transjugular intrahepatic portosystemic shunt (TIPS) treatments in patients with peristomal variceal bleeding. MATERIALS AND METHODS: Ten patients who underwent sclerotherapy (n = 3 patients), TIPS placement (n = 5 patients) or both (n= 2 patients) for peristomal variceal bleeding were retrospectively reviewed. There were 6 women and 4 men, with a mean age of 62.6 years (range: 44-84 years). Data pertaining to the technical aspects of the procedure, demographics, and information regarding the underlying cause of ostomy and portal hypertension were collected. Treatment was considered a primary success if no further hemorrhage occurred. RESULTS: No differences in primary success were found between TIPS cohort (100%) and sclerotherapy cohort (40%) (P=0.4). Sclerotherapy patients had a poorer nutritional status (mean albumin serum level of 2.04g/dL in the sclerotherapy group and 2.95g/dL in theTIPS group; P=0.04) and worse liver function (mean total bilirubin serum level of 4.9mg/dL in the sclerotherapy group and 1.6mg/dL in the TIPS group; P=0.07). CONCLUSION: While further investigation is needed, TIPS may be more effective than sclerotherapy in treating peristomal variceal bleeding. However, sclerotherapy may serve as an effective bridging mechanism in critically ill patients. PMID- 30279100 TI - Increasing ethanol yield through fiber conversion in corn dry grind process. AB - Conversion of corn fiber to ethanol in the dry grind process could increase ethanol yields, reduce downstream processing costs and improve overall process profitability. This work investigates the in-situ conversion of corn fiber into ethanol (cellulase addition during simultaneous saccharification and fermentation) during dry grind process. Addition of 30 FPU/g fiber cellulase resulted in 4.6% increase in ethanol yield compared to the conventional process. Use of excess cellulase (120 FPU/g fiber) resulted in incomplete fermentation and lower ethanol yield compared to the conventional process. Multiple factors including high concentrations of ethanol and phenolic compounds were responsible for yeast stress and incomplete fermentation in excess cellulase experiments. PMID- 30279101 TI - Nitrogen removal through "Candidatus Brocadia sinica" treating high-salinity and low-temperature wastewater with glycine addition: Enhanced performance and kinetics. AB - Freshwater-derived anaerobic ammonia oxidation (anammox) bacteria ("Candidatus Brocadia sinica") were investigated to remove nitrogen from high-salinity and low temperature wastewater with glycine addition. The reactor was operated at 15 +/- 0.5 degrees C with influent pH of 7.5 +/- 0.1. When glycine were 0.2, 0.4, and 0.6 mM, respectively, nitrite removal rate (NRR) increased by 27.7%, 47.3%, and 70.4% accordingly. Optimal ammonia removal rate (0.32 kg/(m3.d)) and NRR (0.45 kg/(m3.d)) were achieved at 0.8 mM glycine. Effect resulting from glycine on nitrite reductase was higher than hydrazine synthase. Moreover, DeltaNO2- N/DeltaNH4+-N increased with glycine addition while DeltaNO3--N/DeltaNH4+-N first increased and then decreased. The remodified Logistic model and modified Boltzmann model were appropriate to describe nitrogen removal with glycine addition. Kinetic parameter lambda achieved through the remodified Logistic model revealed that "Candidatus Brocadia sinica" had a shorter lag phase than that of marine anammox bacteria. PMID- 30279102 TI - [Who will guard the guardians?] PMID- 30279103 TI - The Effect of Surgical Treatment for Gynecomastia on Quality of Life in Adolescents. AB - PURPOSE: Despite the psychosocial deficits associated with gynecomastia, surgical treatment of adolescent gynecomastia remains controversial. This longitudinal cohort study measures changes in health-related quality of life following surgical treatment of gynecomastia in adolescents. METHODS: The following surveys were administered to adolescents with gynecomastia and male controls, aged 12-21 years: Short-Form 36v2 (SF-36), Rosenberg Self-Esteem Scale (RSES), and Eating Attitudes Test-26. Subjects completed surveys at baseline and postoperatively/at follow-up at 6 months, 1 year, 3 years, and 5 years. RESULTS: From 2008 to 2017, 44 patients undergoing surgical treatment of gynecomastia and 64 unaffected male controls participated in our study. At baseline, gynecomastia patients scored significantly worse than controls on the RSES and in five SF-36 domains: general health, vitality, social functioning, role-emotional, and mental health. Scores significantly improved postoperatively on the RSES, and in four SF-36 domains: physical functioning, role-physical, bodily pain, and social functioning. Postoperatively, gynecomastia subjects scored similarly to controls in all SF-36 domains and the RSES. Young and overweight/obese patients and those with severe gynecomastia had the greatest postoperative improvement across survey measures. CONCLUSIONS: Surgical treatment of gynecomastia significantly improves the quality of life of adolescents, with measurable improvements in physical and psychosocial functioning. Postoperatively, gynecomastia patients performed comparably to unaffected controls. Surgical treatment of gynecomastia in adolescents and young men has the potential to significantly improve quality of life, particularly in younger and overweight/obese patients and those with moderate to severe gynecomastia. Concerns regarding patient age and body mass index alone should not contraindicate surgery. PMID- 30279104 TI - Somatic Symptom Disorders in Adolescent Inpatients. AB - PURPOSE: There are only a few reports of adolescents with somatic disorders (SDs) whose symptoms are sufficiently severe to require hospital admission. The aim of this study was to describe the symptom profile, health service utilization, and outcome of adolescents with SDs admitted to a tertiary children's hospital. METHODS: A retrospective cohort study of all adolescents admitted to the Adolescent Medicine Unit of a tertiary children's hospital was undertaken from July 2013 to June 2014. In a two-stage process, medical records were examined to identify patients who met the diagnostic criteria for SD. Evidence of functional recovery was obtained for the period from 18 to 30 months after discharge and rated as completely recovered, partially recovered, or functionally disabled. RESULTS: A total of 60 admissions (53 patients, 79% female) were identified with SD, accounting for 12% of the unit's admissions and 2% of hospital admissions over 12 years old. Nearly half (45%) the presenting symptoms were neurological and 39% involved pain. In total, 20% of admissions were for complex symptoms involving multiple body systems. The majority (81%) of adolescents with follow-up documentation (n = 37) demonstrated complete or partial recovery. Patients whose families fully accepted the diagnosis were more likely to accept counseling following discharge (p < .001) and were almost 20 times more likely to have completely recovered compared to adolescents whose families partially accepted or rejected the diagnosis (odds ratio 17.36, p = .003). CONCLUSIONS: Hospitalized adolescents with SD utilize substantial resources due to the requirement for comprehensive assessment, including multidisciplinary communication. Recovery can be anticipated for the majority, especially if supported by parents. PMID- 30279105 TI - Longitudinal Change in Parent-Adolescent Communication About Sexuality. AB - PURPOSE: Research suggests that parents can be important sources of sex education for their children, but we know little about how this type of communication changes developmentally. Thus, the current study explored longitudinal change in child-, mother-, and father-reports of parent-child communication about sexuality, and how change might be associated with behaviors indicative of sexual risk. METHODS: The sample included 468 adolescents (52% female, 67% white) who participated every year from age 14 to 18, and their mother and father. RESULTS: Growth-curve analyses revealed relatively low and stable levels of parent-child communication from all three reporters, with some differences as a function of reporter and child gender. Results also suggested that initial levels and change in parent-child communication over time were associated with child-reports of safer sex at the final time point (age 21). CONCLUSIONS: The discussion focuses on developmental approaches to parent-child sex communication and the need for future research. PMID- 30279106 TI - An alternative approach to the intraoperative Indocyanine Green angiography (ICGA) in reconstructive surgery. PMID- 30279107 TI - The Helsinki approach to face transplantation. AB - AIM: We herein describe the establishment of the Helsinki Vascularized Composite Allotransplantation (VCA) program and its execution in the first two face transplant cases. METHODS & PATIENTS: The Helsinki VCA program initially required the fulfillment of legal, hospital, financial, and ethical requirements. Thereafter, the assembling of a multidisciplinary team commenced. A team of Plastic, maxillofacial and ENT surgeons comprise the facial VCA team. The protocol involves collaboration with the Solid Organ Transplant (SOT) team, transplant immunology, immunosuppression, microbiology, psychiatric evaluation, well-defined VCA indications and informed consent. Between 2011 and 2017 two patients were selected for transplantation. Both patients had a severe composite facial deformity involving the maxilla and mandible following earlier ballistic injury. RESULTS: Patient 1 was a 35 year-old male who underwent successful near total face transplantation in February 2016 and at 30 months he has a good aesthetic outcome with symmetrical restoration of the central face and good sensory and symmetrical motor functional outcomes. Patient 2 was a 58 year-old male who underwent full face transplantation in March 2018 and at 5 months he has recovered without major problems. CONCLUSION: A successful facial VCA program requires a well-prepared research protocol, experts from multiple specialties and careful patient selection. The establishment of the Helsinki VCA program required long and thorough planning and resulted in the first two Nordic face transplantation cases. This protocol now forms the platform (as a proof of concept) for other types of vascularized composite allotransplantations. PMID- 30279108 TI - Minimally Invasive Cardiac Surgery Without Peripheral Cannulation: A Single Centre Experience. AB - BACKGROUND: A minimally invasive approach without any peripheral cannulation was used as an alternative to median sternotomy for the correction of a wide range of cardiac defects with superior results and good cosmetic outcome. METHODS: From October 2015 to March 2017, 145 patients underwent correction of congenital cardiac malformations with cardiopulmonary bypass through right anterior minithoracotomy (RAMT) with routine cannulation. The average age was 9.69+/ 4.38years (range 2-21) and the average body surface area was 0.91+/-0.27square metres (range 0.5-1.7). The corrected defects included all types of atrial septal defect (ASD) and ventricular septal defects (VSD), partial atrioventricular septal defects with severe mitral regurgitation, mitral valve repair, repair of tetralogy physiology requiring outlet patch enhancement, isolated pulmonary stenosis (PS) and congenital coronary cameral fistula. RESULTS: There was no operative mortality or major morbidity. All patients were alive at the time of this follow-up. The mean cardiopulmonary bypass time was 64.75+/-22.28minutes (range 30-175) and mean aortic cross clamp time was 37.53+/-18.23minutes (range 14-135). Fifty-five patients were extubated in the operating room and the remaining 90 patients were extubated within 3hours in the intensive care unit. Repair and cosmetic results were excellent in all patients. There were no conversions to full sternotomy. No neurological events were reported. CONCLUSIONS: Right anterior minithoracotomy without peripheral cannulation is safe and effective for the correction of a wide range of congenital heart defects including right ventricular outlet obstructions. The cosmetic results are satisfactory, avoiding psychosocial problems. PMID- 30279109 TI - Predictors of Distant Failure After Stereotactic Body Radiation Therapy for Stages I to IIA Non-Small-Cell Lung Cancer. AB - PURPOSE: The use of stereotactic body radiation therapy (SBRT) has emerged as an effective treatment modality for patients with early-stage non-small-cell lung cancer (NSCLC), with excellent local control rates. Despite this, there is a predominant pattern of distant failure. We sought to identify factors that help predict which patients with stages I to IIA NSCLC treated with SBRT are at highest risk of distant failure, so that we may utilize these factors in the future to help determine which patients may benefit from the addition of systemic therapies. PATIENTS AND METHODS: We retrospectively reviewed 292 patients treated with SBRT for early stage NSCLC from 2006 to 2016 at 2 institutions. Patients were classified by T stage, tumor size, location and histology, pretreatment positron emission tomography/computed tomography (PET/CT) standardized uptake value (SUV), smoking status, and age. The primary endpoint of the study was distant failure. We aimed to analyze if patient characteristics could be identified that predicted for distant failure through the use of competing risk analysis. RESULTS: The median follow-up was 21.9 months. The median dose of radiation and fractionation delivered was 50 Gy (range, 45-65 Gy) in 5 fractions (range, 3-13 fractions). The median patient age was 72.8 years (interquartile range, 65.4-79.7 years). The 2-year distant failure was 22.0%, and overall survival at 2 years was found to be 61.0%. For every 1-year increase in patient age, the hazard of distant failure at any given time was 3% lower (hazard ratio, 0.97; 95% confidence interval, 0.94-0.99; P = .04). None of the remaining characteristics emerged as significant risk factors for distant failure on univariable or multivariable analysis. CONCLUSIONS: Overall, our cohort had distant failure and survival rates comparable with what has been described in the literature. Although we were unable to identify factors outside of age that correlated to risk of distant failure, this topic warrants further investigation, as distant failure is the primary pattern of failure with SBRT when used as the primary management for early-stage NSCLC. Additional molecular studies are needed to further inform on the role of systemic therapy in patients with early-stage NSCLC to improve clinical outcomes. PMID- 30279110 TI - Targeted Tissue and Cell-Free Tumor DNA Sequencing of Advanced Lung Squamous-Cell Carcinoma Reveals Clinically Significant Prevalence of Actionable Alterations. AB - BACKGROUND: Major guidelines do not recommend routine molecular profiling of lung squamous-cell carcinoma (LUSC) because the prevalence of actionable alterations is thought to be low. Increased utilization of next-generation sequencing (NGS), particularly with cell-free circulating tumor DNA, facilitates reevaluation of this premise. PATIENTS AND METHODS: We retrospectively evaluated the prevalence of actionable alterations in 2 distinct LUSC cohorts totaling 492 patients. A total of 410 consecutive patients with stage 3B or 4 LUSC were tested with a targeted cell-free circulating DNA NGS assay, and 82 patients with LUSC of any stage were tested with a tissue NGS cancer panel. RESULTS: In the overall cohort, 467 patients (94.9%) had a diagnosis of LUSC, and 25 patients (5.1%) had mixed histology with a squamous component. A total of 10.5% of the LUSC subgroup had somatic alterations with therapeutic relevance, including in EGFR (2.8%), ALK/ROS1 (1.3%), BRAF (1.5%), and MET amplification or exon 14 skipping (5.1%). Sixteen percent of patients with mixed histology had an actionable alteration. In the LUSC subgroup, 3 evaluable patients were treated with targeted therapy for an actionable alteration; all of them experienced partial response. CONCLUSION: In this large, real-world LUSC cohort, we observed a clinically significant prevalence of actionable alterations. Accurate local histopathologic assessment in advanced-stage LUSC can be challenging. Further evaluation of the genomic landscape in this setting is warranted to potentially identify underappreciated treatment options. PMID- 30279111 TI - Cell-Free DNA Next-Generation Sequencing Prediction of Response and Resistance to Third-Generation EGFR Inhibitor. AB - INTRODUCTION: The genomic alterations driving resistance to third-generation EGFR tyrosine kinase inhibitors (TKIs) are not well established, and collecting tissue biopsy samples poses potential complications from invasive procedures. Cell-free circulating DNA (cfDNA) testing provides a noninvasive approach to identify potentially targetable mechanisms of resistance. Here we utilized a 70-gene cfDNA next-generation sequencing test to interrogate pretreatment and progression samples from 77 EGFR-mutated non-small cell lung cancer (NSCLC) patients treated with a third-generation EGFR TKI. PATIENTS AND METHODS: Rociletinib was evaluated in advanced or metastatic (second line or higher) disease with EGFR T790M positive NSCLC in the TIGER-X (NCT01526928) and TIGER-2 (NCT02147990) studies. Plasma samples were collected at baseline and at the time of systemic progression while receiving rociletinib. The critical exons in 70 genes were sequenced in cfDNA isolated from plasma samples to elucidate a comprehensive genomic profile of alterations for each patient. RESULTS: Plasma-based cfDNA analysis identified 93% of the initial EGFR activating and 85% of the EGFR T790M resistance mutations in pretreatment samples with detectable tumor DNA. Profiling of progression samples revealed significant heterogeneity, with different variant types (eg, mutations, amplifications, and fusions) detected in multiple genes (EGFR, MET, RB1) that may be driving resistance in patients. Novel alterations not previously described in association with resistance to third-generation TKIs were also detected, such as an NTRK1 fusion. CONCLUSION: cfDNA next-generation sequencing identified initial EGFR activating and secondary T790M resistance mutations in NSCLC patients with high sensitivity, predicted treatment response equivalent to tissue analysis, and identified multiple novel and established resistance alterations. PMID- 30279112 TI - Emergence of a carbapenem-resistant and colistin-heteroresistant Enterobacter cloacae clinical isolate in Japan. AB - A carbapenem-resistant and colistin-heteroresistant clinical isolate of Enterobacter cloacae was obtained from an inpatient in Okinawa, Japan. The minimum inhibitory concentrations of both imipenem and meropenem were 32 MUg/mL. The isolate showed heteroresistance to colistin using the Etest method and resistance to colistin using the broth microdilution method. It had a disrupted ompC and a mutation in the promoter region of blaACT-2, but did not harbor any genes encoding carbapenemase. The disruption of ompC and the mutation in blaACT-2 was associated with the carbapenem resistance of this isolate. This isolate also had mutations in pmrAB and phoPQ encoding two-component regulatory systems, which may be associated with colistin heteroresistance. PMID- 30279113 TI - Comparative analysis of methicillin-resistant Staphylococcus aureus isolated from outpatients of dermatology unit in hospitals and clinics. AB - Community-onset methicillin-resistant Staphylococcus aureus (CO-MRSA) is a causative agent of intractable skin infections. In general, clinical symptoms of hospital outpatients with skin infections are severer than those of clinic patients. Hence, molecular epidemiological features of the CO-MRSA strains from hospital outpatients are predicted to be different from those of clinic patients. Here, we conducted a comparative analysis for CO-MRSA isolates from outpatients with impetigo in hospitals and clinics located in the same district of Tokyo, Japan. Incidence of MRSA infection was higher in hospital outpatients (21.5%, 20/93 isolates) than in clinic patients (14.5%, 121/845 isolates). The resistance rate to clindamycin, which is a common topical antimicrobial agent in dermatology, in the isolates from hospital outpatients (60.0%) was higher than those from clinic patients (31.4%). Proportion of the staphylococcal cassette chromosome (SCC) mec type II, which is a representative type of hospital-acquired MRSA in Japan, in the isolates from hospital outpatients (65.0%) was significantly higher than those from clinic patients (30.6%) (P < 0.01). Multilocus sequence typing showed that the clonal complex 89-SCCmec type II (CC89 II) clone, which exhibits clindamycin resistance, was the most predominant (55.0%) in the isolates from hospital outpatients. On the other hand, all CC8-IV, CC121-V, and CC89-V clones accounted for 60% in clinic patients were susceptible to clindamycin. Our findings suggested that the clindamycin-resistant CC89-II CO MRSA clone might be more related to skin infections in hospital outpatients than clinic patients. PMID- 30279114 TI - Antimicrobial susceptibility of Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis clinical isolates from children with acute otitis media in Japan from 2014 to 2017. AB - Increase in antimicrobial resistance (AMR) among pathogenic bacteria is a serious threat to public health. Surveillance studies to monitor shifting trends in resistance are important and guide the selection of appropriate antimicrobial agents for a particular organism. Furthermore, these studies help in dissemination of accurate information regarding AMR to the public. In this study, we investigated the antimicrobial susceptibility patterns of Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis clinical isolates from outpatient children with acute otitis media in Japan from 2014 to 2017. A total of 8693 strains (2415 of S. pneumoniae, 3657 of H. influenzae, and 2621 of M. catarrhalis) were clinically isolated, and their antimicrobial susceptibilities to benzylpenicillin (PCG), ampicillin (ABPC), amoxicillin clavulanic (AMPC/CVA), azithromycin (AZM), ceftriaxone (CTRX), and levofloxacin (LVFX) were investigated. Based on the minimum inhibitory concentration (MIC) breakpoints, the average proportion of S. pneumoniae isolates non-susceptible to PCG and AZM was 38.2% and 82.0% respectively. The average proportion of H. influenzae isolates non-susceptible to ABPC, CVA/AMPC, and CTRX was 61.9%, 43.5%, and 49.4%, respectively. The high prevalence of these resistant organisms is attributed to frequent use of antibiotic agents in Japan. Moreover, the proportion of LVFX-non-susceptible H. influenzae isolates increased in this four year study. Here, we report updates regarding the AMR trends amongst the major pathogens that cause acute otitis media in Japan. Continuing surveillance of antimicrobial susceptibility and application of control measures against further transmission are required to decrease the emergence of resistant strains. PMID- 30279115 TI - Denosumab Toxicity When Combined With Anti-angiogenic Therapies on Patients With Metastatic Renal Cell Carcinoma: A GETUG Study. AB - BACKGROUND: About one-third of patients with renal cell carcinoma (RCC) have detectable metastases at diagnosis. Among them, bone is the second most frequent metastatic site. Treatment of metastatic RCC mostly relies on anti-angiogenic (AA) therapies and, more recently, immunotherapy. Skeletal-related events (SREs) can be prevented with bone-targeted therapies such as denosumab (Dmab), which has demonstrated superiority when compared with zoledronic acid in solid tumors. However, there is limited available data on Dmab toxicity in combination with AA therapies in patients with kidney cancer. The objective of this study was to retrospectively analyze the toxicity profile (mainly osteonecrosis of the jaw [ONJ] and hypocalcemia) in patients with metastatic renal cell carcinoma (mRCC) treated with Dmab and AA therapy combination. PATIENTS AND METHODS: We conducted a multicenter retrospective study among centers from the French Groupe d'Etudes des Tumeurs Uro Genitales (GETUG). Patients with bone metastases who received concurrently or sequentially AA therapy and Dmab were included in this study. RESULTS: A total of 41 patients with mRCC were enrolled. Although no patient presented with severe hypocalcemia, ONJ occurred in 7 (17%) of 41 patients. Interestingly, all patients with ONJ received the Dmab and AA combination in the first line of treatment; among these patients, 3 patients had no risk factor other than the Dmab and AA combination. CONCLUSION: The incidence of ONJ was high in this real-life population of patients with mRCC treated with AA therapies combined with Dmab. This toxicity signal should warn physicians about this combination in the mRCC population.

PMID- 30279117 TI - The value of the Evans and bicaudate indices for predicting poor cognitive performance and central atrophy. Results from the Atahualpa Project. AB - Recent studies suggested that both the Evans index (EI) and the bicaudate index (BI) are predictive markers of central atrophy and, as such, have been inversely associated with cognitive performance. This study investigated whether the EI and the BI (independently and combined) correlated with the MoCA score by means of generalized linear models adjusted for relevant confounders. Using a population based design, 618 Atahualpa residents aged >=40 underwent a head CT and MoCA testing. Both, the EI and the BI, were independently calculated by two readers, and a mean of the two values for each index was calculated for analysis. Generalized linear models showed inverse significant relationships between the EI and the BI with the MoCA score (p = 0.034, and p < 0.001, respectively). When both predictive variables (EI and BI) were included in a generalized linear model adjusted for all confounders, the BI remained significantly associated with the MoCA score (p = 0.004) but the EI did not (p = 0.677). This study shows that only the BI has and explanatory power outside the endogenous construct (central atrophy) for which both, the BI and the EI are part and parcel of. PMID- 30279118 TI - Analysis for risk factors of 12-month neurological worsening in patients with surgically treated small-to-moderate size unruptured intracranial aneurysms. AB - The risk associated with surgical treatment for small-to-moderate size unruptured intracranial aneurysms (SMUIAs, defined as <15 mm) has not been well characterized. Authors aimed to investigate risk factors for poor outcome in surgical treatment of SMUIAs. The data of prospectively collected 801 consecutive patients harboring 971 surgically treated SMUIAs was evaluated. Neurological worsening (NW) was defined as an increase in 1 or more modified Rankin Scale at 12-month. Clinical and radiological characteristics were compared. Neurological worsening was observed in 45 (4.6%). In multivariate analysis, only perforator territory infarction (PTI) on postoperative diffusion-weighted imaging (odds ratio (OR), 13; 95% confidence interval (CI), 4.9-32, p < 0.0001), and aneurysm locations (paraclinoid (OR, 6.9; 95% CI, 3.1-15, p < 0.0001), basilar artery (OR, 4.5; 95% CI, 1.5-14, p = 0.008), vertebral artery (OR, 11; 95% CI, 3.3-34, p < 0.0001)) were related to neurological worsening. Multivariate analysis showed that statin use (OR, 12; 95% CI, 3.8-39, p < 0.0001) and aneurysm locations (internal carotid artery-posterior communicating artery (OR, 3.9; 95% CI, 1.8 8.2, p < 0.0001) and basilar artery (OR, 6.3; 95% CI, 2.3-17, p = 0.008)), and aneurysm size >10 mm (OR, 5.3; 95% CI, 1.8-15, p = 0.003) were related to PTI. Although all SMUIAs should be carefully considered whether to be treated, those with statins, specific locations, and larger sizes should perhaps be more meticulously contemplated, and neurosurgeons should continue to avoid PTI. PMID- 30279119 TI - Pre-operative planning and rod customization may optimize post-operative alignment and mitigate development of malalignment in multi-segment posterior cervical decompression and fusion patients. AB - : Patient-specific rods designed based on a particular pre-operative plan are a recent advancement to help achieve desired operative alignment goals. This study investigated the role of pre-operative planning and patient-specific rods on post operative alignment and outcomes. Patients were grouped according to use of pre operative planning and patient-specific, pre-contoured rods (PLAN) or absence of planning/rods (NON). Pre-operative and post-operative alignment were measured: cervical sagittal vertical axis (cSVA), cervical lordosis (CL), T1 Slope minus CL (TS-CL). Alignment differences between the groups were assessed using independent and paired samples t-tests. 34 patients were identified (15 PLAN, 19 NON). Pre- and post-operative CL, cSVA and TS were similar between the two groups (p > 0.05), though pre-operative TS-CL was slightly higher in PLAN patients (28.13 degrees versus 18.42 degrees , p = 0.049). There were no improvement differences pre- to post-operative for CL, cSVA and TS between the groups (p > 0.05). However, PLAN patients exhibited a greater correction of TS-CL, with an average of 5.8 degrees decrease versus a 3.5 degrees increase in TS-CL for NON patients (p = 0.015). PLAN patients did not demonstrate a significant change from pre- to post-operative alignment for cSVA or TS-CL (cSVA: 27.5 mm to 31.1 mm, p = 0.255; TS-CL: 28.1 degrees to 22.3 degrees , p = 0.13), though their TS-CL did trend towards significant post-operative improvement. In contrast, NON patients worsened in cSVA and TS-CL post-operatively (cSVA: 21.8 mm to 30.3 mm, p < 0.001; TS-CL: 18.4 degrees to 22.0 degrees , p = 0.035). Multi-segment posterior decompression and fusion patients have the potential to worsen with regards to post-operative alignment without pre-operative planning. Patients with pre contoured rods and pre-operative planning exhibited a greater correction of TS-CL after surgery than un-planned cases, though limited by the pre-operative difference in cervical-thoracic mismatch between planned and unplanned cases. LEVELS OF EVIDENCE: III. PMID- 30279120 TI - Preoperative embolization of skull base meningiomas: A systematic review. AB - Neoadjuvant endovascular embolization of skull base meningiomas may facilitate surgical resection, thereby potentially decreasing operative morbidity. However, due to variation in the reported efficacy and complication rates, the utility of embolization remains incompletely defined. The aim of this systematic review is to assess the outcomes of preoperative embolization for skull base meningiomas. A literature review was performed to identify studies reporting outcomes of patients with skull base meningiomas who underwent preoperative embolization. Baseline, treatment, and outcomes data were analyzed. Major complications included death, new cranial neuropathy, retinal artery ischemia, permanent neurologic deficit, or intracerebral hemorrhage. The pooled analysis consisted of 15 studies, comprising a total of 403 patients with skull base meningiomas treated with preoperative embolization. The most common locations were the sphenoid wing (34%, 87/256 cases), petroclival region (31%, 80/256 cases), and cavernous sinus (12%, 31/256 cases). The median tumor size ranged from 5.0 to 8.0 cm. Based on pooled data, angiographic absence of tumor blush was achieved in 17% (13/79 cases). The median estimated blood loss (EBL) ranged from 225 to 580 mL. Simpson grade I-III resection was achieved in 74% (40/54) of patients. The overall complication, major complication, and mortality rates were 12% (47/403 patients), 6% (21/328 patients), and 0.2% (1/403 patients), respectively. Preoperative embolization is a reasonable adjunct to resection for appropriately selected skull base meningiomas. Future comparative analyses are necessary to ascertain the benefits of preoperative embolization of skull base meningiomas with respect to extent of resection, operative duration, operative blood loss, and surgical morbidity.

PMID- 30279122 TI - Chiari malformation clusters describe differing presence of concurrent anomalies based on Chiari type. AB - Chiari malformations are structural defects in the posterior fossa where the cerebellum displaces caudally into the foramen magnum and upper spinal canal. These malformations are classified by severity as Types 1-4, each presenting with different associated and/or concurrent conditions and anomalies. The aim of this study was to utilize a nationwide database to study patients with Chiari malformations including their concurrent diagnoses and associated anomalies. Using a retrospective review of the Nationwide Inpatient Sample (NIS) database from 2003 to 2012, Chiari malformations were assessed by Chiari type and rates of concurrence for various additional anomalies were evaluated using cross tabulations. There were 305,726 national cases of Chiari Type 1, 119,632 cases of Chiari Type 2, 15,540 cases of Type 3, and 79,663 cases of Type 4. Overall 44.3% of Chiari patients have at least one concurrent anomaly. Stratified by Chiari Type, 7.1% of Type 1 patients, 12.3% of Type 2, and 100% of Type 3 and 4 have at least one concurrent anomaly. The most common isolated neurologic associations were tethered cord, syringomyelia, and hydrocephalus, while the most common anomaly clusters were syringomyelia and scoliosis in Type 1 (0.63), tethered cord syndrome and scoliosis (0.72%) in Type 2, encephalocele and acquired hydrocephalus (11.45%) in Type 3, and reduction deformity of the brain with acquired hydrocephalus (15.95%) in Type 4. Chiari malformations have strong associations with other abnormalities outside of known relationships in the current classification. While neurologic abnormalities are most common, additional body systems are frequently involved especially with worsening hindbrain defects. PMID- 30279123 TI - Surgical decision-making in degenerative cervical myelopathy - Anterior versus posterior approach. AB - Surgery is the only effective treatment option for advanced degenerative cervical myelopathy. Decompression may be achieved via either an anterior or posterior approach. They are both well-established techniques that are used to achieve optimal clinical results with each approach having its own pros and cons. Generally, the approach is dictated by preoperative imaging features with the aim of directly addressing the sources of spinal cord compression. However, there are frequently multiple sources of compression and several other factors should be also considered. The posterior approach is optimal for multilevel stenosis using consecutive laminectomies. Conversely, in cases of rigid kyphosis, the anterior approach is preferable as it enables thorough decompression and lordotic realignment. The existence of radiculopathy, neck pain and dysphagia should be carefully considered, and patients' occupational and cosmetic demands must be also discussed given the risk of voice change and scar formation. Body habitus or previous history of skin incision or radiation may also influence the decision. Since the clinical benefit seems to be similar between the two approaches, the decision has to be made on a case-by-case basis depending on the surgeons' experiences and preferences. PMID- 30279124 TI - Phenotypic spectrum of patients with cystic fibrosis and cystic fibrosis-related disease carrying p.Arg117His. AB - BACKGROUND: The "mild" gene variant, p.Arg117His in cystic fibrosis (CF) results in highly variable phenotypes ranging from male infertility to severe lung disease. Due to current interest to include this group in CFTR-targeted therapies, this study aims to describe the disease spectrum. METHODS: Retrospective study of Toronto CF and CFTR-related p.Arg117His patients. Longitudinally captured clinical data were compared between patients with 5T/7T variants and those with a CF or CFTR-related diagnosis. Comparison was made between p.Arg117His adults and infants identified through CF newborn screening (NBS). RESULTS: Twenty of fifty patients carried the 5T variant, all with a diagnosis of CF (p.Arg117His-5TCF), and 30/50 carried 7T, 7 diagnosed with CF (p.Arg117His-7TCF) and 23 with a CFTR-related disorder (p.Arg117His-7TCFTR). For those with chest HRCT results available, 75% p.Arg117His-5TCF, 33% p.Arg117His 7TCF and 27% p.Arg117His-7TCFTR patients had bronchiectasis. Further, 79% p.Arg117His-5T, 29% p.Arg117His-7TCF and 13% p.Arg117His-7TCFTR had abnormal lung function. Of those, 80% grew CF-related pathogens on respiratory culture. Interestingly, the mean maximum sweat chloride and the percentage of patients growing CF-related bacterial pathogens were identical in p.Arg117His-7 TCFTR adults and p.Arg117His infants. CONCLUSIONS: Generally, p.Arg117His-5T patients had more severe CF disease. However, a subset of p.Arg117His-7 T patients demonstrated equally severe disease, thus warranting clinical monitoring of all p.Arg117His patients including p.Arg117His infants identified via NBS. PMID- 30279125 TI - IVACAFTOR restores FGF19 regulated bile acid homeostasis in cystic fibrosis patients with an S1251N or a G551D gating mutation. AB - OBJECTIVE: Disruption of the enterohepatic circulation of bile acids (BAs) is part of the gastrointestinal phenotype of cystic fibrosis (CF). Ivacaftor (VX 770), a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator, improves pulmonary function in CF patients with class III gating mutations. We studied the effect of ivacaftor on the enterohepatic circulation by assessing markers of BA homeostasis and their changes in CF patients. METHODS: In CF patients with an S1251N mutation (N = 16; age 9-35 years S125N study/NTR4873) or a G551D mutation (N = 101; age 10-24 years; GOAL study/ NCT01521338) we analyzed plasma fibroblast growth factor 19 (FGF19) and 7alpha-hydroxy-4-cholesten-3-one (C4) levels, surrogate markers for intestinal BA absorption and hepatic synthesis, respectively, before and after treatment with ivacaftor. RESULTS: At baseline, median FGF19 was lower (52% and 53%, P < .001) and median C4 higher (350% and 364%, P < .001), respectively, for the S1251 N and G551D mutation patient groups compared to healthy controls. Treatment with ivacaftor significantly increased FGF19 and reduced C4 levels towards normalization in both cohorts but this did not correlate with CFTR function in other organs, as measured by sweat chloride levels or pulmonary function. CONCLUSIONS: We demonstrate that patients with CFTR gating mutations display interruption of the enterohepatic circulation of BAs reflected by lower FGF19 and elevated C4 levels. Treatment with ivacaftor partially restored this disruption of BA homeostasis. The improvement did not correlate with established outcome measures of CF, suggesting involvement of modulating factors of CFTR correction in different organs.

AB - Pyropia yezoensis is an economically important marine macroalgae, naturally distributed in the upper intertidal zone. Owing to the nature of its habitat, the thallus will periodically be exposed to seawater or atmosphere, and can lose up to 95% of its cellular water content. This makes the alga an ideal research model to investigate the mechanisms of desiccation tolerance. In this study, we investigated the response mechanisms to dehydration and rehydration stresses at the transcription level in Pyropia yezoensis. The differently expressed genes were analyzed based on the different functions of encoding proteins: effector proteins (chloroplast proteins, macromolecular protective substances, and toxicity degradation enzymes) and regulatory proteins (protein kinases and phosphatases). Under osmotic stress, the unigenes related to photosynthesis were down-regulated significantly while those encoding glutathione transferase, superoxide dismutase and heat shock proteins were up-regulated significantly. We inferred that the photosynthetic activity was reduced to prevent damage caused by photosynthetic by-products and that the expression of antioxidant enzyme was increased to prevent the damage associated with reactive oxygen species. Additionally, unigenes encoding serine/threonine kinases and phospholipases were up-regulated in response to osmotic stress, indicating that these kinases play an important role in osmotolerance. Our work will serve as an essential foundation for the understanding of desiccation tolerance mechanisms in Pyropia yezoensis in the upper intertidal zones of rocky coasts. PMID- 30279128 TI - Spatial analysis of disparities in asthma treatment among adult asthmatics. AB - BACKGROUND: Spatial analytic techniques can uncover important differences in asthma treatment and identify geographic areas with poor asthma management. OBJECTIVE: To review geographical differences in asthma treatment in an adult asthmatic population. METHODS: This was a retrospective, cross-sectional chart review study (n = 519) using Geographic Information System approaches to determine the impact of spatial access to pharmacies and other factors on inappropriate rescue and inadequate controller medication use. Statistical analyses included chi-square test for categorical variables and Kruskall-Wallis test for continuous variables. Logistic regression was used to determine unadjusted and adjusted odds of inappropriate and inadequate pharmaceutical management of asthma based upon distance to pharmacy and other factors. Choropleth maps were constructed to display zip code level variation of asthma management. RESULTS: Inappropriate medication users lived further from their preferred pharmacy compared to appropriate users (median distances of 3.02 and 1.96 miles respectively; p = 0.01). Inappropriate and inadequate management of asthma varied by zip code, ranging from 5.5 to 17.3% and 25.0-59.6%, respectively. A statistically significant difference in appropriate use by age was found, with nearly 17% of adults age 65 and older overusing their rescue inhaler. Conversely, patients age 18-34 years, 35-49 years, and 50-64 years, used their controller medications inadequately (64.2%, 57.3%, and 48.2%, respectively) compared to 42.5% of patients aged 65 and older. Unadjusted and adjusted analyses showed that former smokers had higher odds of inadequate management of asthma. CONCLUSION: The unadjusted findings suggest that distance to pharmacies may play a role in the pharmaceutical management of asthma, though these findings are explained by confounding factors. Future research should continue to explore the effect of spatial access to pharmacies on chronic disease management and the role that maps can play in guiding medication management interventions in a larger sample to allow for more rigorous analysis. PMID- 30279129 TI - Validation of a risk stratification tool for a Hospital Outreach Medication Review (HOMR) program. AB - BACKGROUND: Early hospital readmissions are a challenging and costly experience for both patients and the healthcare service. Reducing hospital readmission rates is a priority for health services globally and this is evident with the establishment of multiple outpatient services to promote early follow-up and to initiate secondary preventative care measures. One such intervention has been the introduction of a pharmacist-led, Hospital Outreach Medication Review (HOMR) service. However, the demand for the service has meant reaching this target has become an increasingly ambitious goal within allocated resources. OBJECTIVE: To validate a risk-stratification tool to identify low-risk patients in whom a telephone medication review would be a safe and effective alternative to a home based review. METHOD: A risk tool was derived and applied to a retrospective sample to act as the parent cohort. A prospective cohort was stratified into low and high-risk based on this tool, and received either a telephone or a traditional home medication review respectively. RESULTS: 235 patients were included in final analysis (n = 113 prospective, n = 122 baseline controls). High risk patients were more likely to be readmitted at 60 and 90 days in the baseline cohort (9/38 vs 7/84, p = 0.04 and 11/38 vs 9/84, p = 0.02 respectively), with a trend towards increased readmissions at 30 days (5/38 vs 3/84, p = 0.11). Logistic regression identified the risk tool as an independent predictor of hospital readmission (IRR 1.18, p = 0.04), whereas age and Charlson comorbidity were not (p = 0.80 and 0.31 respectively). There was no significant difference between the new model (incorporating phone reviews) and the parent cohort (p = 0.25). CONCLUSION: Our risk score was able to identify those at highest risk of hospital readmission at 60 and 90 days. Utilising this risk score, a telephone HOMR for low-risk patients was a safe and efficient alternative to a traditional home review. PMID- 30279130 TI - Medication prior authorization from the providers perspective: A prospective observational study. AB - BACKGROUND: The prior authorization (PA) process for medications used by community providers requires modernization. Therefore, a deeper understanding of current state of PA from the community provider perspective is imperative to inform and modernize this managed care tool. OBJECTIVES: Objectives of this study were to identify, analyze and categorize the issues associated with the medication PA process from provider practice perspective. METHODS: A prospective non-experimental, cross sectional, observational study was performed using semi structured interviews and direct observation at a convenience sample of eight primary care and medicine subspecialty group practices in Tucson, Arizona, USA. Participating practices were required to have an established medication PA process. The participant feedback from each site was analyzed using the Richards qualitative coding technique that includes descriptive coding, topic coding, and analytical coding. RESULTS: Data were obtained from eight unique community provider offices (8 sites) at which 29 prescribers practice. The pain points identified represented five main categories: 1) information transfer gaps; 2) format disparities; 3) outdated technologies; 4) care consequences; and 5) workarounds. Prescribers and their staff suggested improvements that included real time eligibility and formulary alerts regarding PA during the e-prescribing process, accurate, up-to-date formulary data with easy-to-access alternatives, and embedded PA that is integrated with electronic medical record data. Three sites used medication PA portals such as CoverMyMeds(r) for information gathering, but at the time of data collection, no sites used these PA portals for prospective electronic prior authorization (ePA) or the electronic process of requesting authorization from health plan payers for coverage. CONCLUSION: The PA process for medication used by community providers is in urgent need of modernization. Pain points identified in this study could be alleviated by implementing medication ePA solutions. However, providers and their staff are largely unaware that ePA exists. Additional research in this area is needed. PMID- 30279131 TI - Community pharmacy interventions to improve antibiotic stewardship and implications for pharmacy education: A narrative overview. AB - BACKGROUND: Antibiotic resistance is one of the world's most pressing public health problems, resulting in over 23,000 deaths per year. One of the main contributing factors to antimicrobial resistance is antibiotic misuse and overuse. Community pharmacists can play a role in reducing antibiotic resistance, since they are one of the most accessible healthcare professionals. OBJECTIVE: The purpose of this paper is to describe community pharmacy interventions and strategies to reduce antibiotic misuse and overuse and to discuss the implications for pharmacy training. METHODS: A narrative overview strategy was employed to identify papers on antibiotic stewardship and the role of the community pharmacist. Our review examined potential stewardship strategies and interventions within community pharmacy practice that provide opportunities for pharmacists to engage or lead in the reduction of antimicrobial resistance. RESULTS: We describe five promising community pharmacist-led intervention strategies: Collaborative Practice Agreements (CPAs), point-of-care (POC) testing, patient consultations, academic detailing and serving as an advocate for patients and other healthcare providers CONCLUSIONS: This review highlights topics that may warrant increased attention in pharmacy school curricula. Pharmacy schools may want to consider modifying their curricula to address the shifts in practice of the community pharmacist - emphasizing the expanded role of the pharmacist in patient care and public health issues such as outpatient antibiotic stewardship. PMID- 30279132 TI - Japanese orthopaedic association cervical myelopathy evaluation questionnaire (JOACMEQ): Part 5. Determination of responsiveness. AB - BACKGROUND: In 1999, the Japanese Orthopaedic Association decided to develop a new Cervical Myelopathy Evaluation Questionnaire (JOACMEQ). The final version of the JOACMEQ, comprising 24 questions and five domains (cervical spine function (CF); upper extremity function (UF); lower extremity function (LF); bladder function (BF); and quality of life (QOL)), was established after three nationwide investigations. The fourth investigation, reported in this paper, was performed to confirm the responsiveness of the questionnaire. METHODS: A total of 137 patients with cervical myelopathy were included in the study. Each patient was interviewed twice using the JOACMEQ before and after treatment. At the second interview, the patients self-rated their condition in five domains for "worse," "somewhat worse," "no change," "somewhat better," or "better," and these scores were defined as the external assessment rating. The difference of the points in five domains between the first and the second interview was calculated against each external assessment. Based on the results, substantial clinical benefit (SCB) thresholds for the JOACMEQ were determined. RESULTS: The statistically significant median values of the acquired points were 17.5 for CF, 16.0 and 21.0 for UF, 27.0 and 20.5 for LF, 13.0 for BF, and 29.0 for QOL. After consideration of the results, the committee decided that an acquired point >=20 could be interpreted as representing an SCB threshold for the JOACMEQ. CONCLUSION: We have concluded that a treatment can be judged to be effective for a patient if 1) The patient give all answers for the questions necessary to calculate the functional score of a domain and an increase of >=20 points is obtained for that score, or 2) The functional score after treatment is > 90 points even if the answer for the unanswered questions was supposed to be the worst possible choice. PMID- 30279133 TI - Dose optimization of topical tranexamic acid for primary total hip arthroplasty: A prospective cohort study. AB - BACKGROUND: Recently, the topical application of tranexamic acid has become widespread, and it is effective in reducing postoperative blood loss and transfusion rate in total hip arthroplasty. There is no consensus on the optimal dose of topical tranexamic acid. This study aimed to assess the efficacy and safety of topical tranexamic acid on postoperative blood loss and determine the optimal topical dose for primary total hip arthroplasty. METHODS: This prospective cohort study with a robust protocol enrolled 79 patients who received either 1 or 2 g of topical tranexamic acid in 30 mL normal saline solution or an equivalent volume of normal saline at the end of surgery. The primary outcomes were postoperative drain blood loss and hemoglobin decrease on postoperative day 7. The secondary outcomes were transfusion rate, d-dimer level on postoperative day 7, symptomatic deep vein thrombosis rate, and duration of hospital stay. RESULTS: Both 1 and 2 g tranexamic acid significantly reduced postoperative drain blood loss (p < 0.001). These doses also reduced the hemoglobin concentration decrease on postoperative day 7, but not significantly. Furthermore, 1 and 2 g doses of tranexamic acid had similar effects on postoperative blood loss and hemoglobin concentration decrease. There was no difference in the transfusion rate, d-dimer level, symptomatic deep vein thrombosis rate, and length of hospital stay. CONCLUSIONS: The use of topical tranexamic acid at the end of surgery is effective and safe for reducing postoperative blood loss in primary total hip arthroplasty. Topical tranexamic acid at a dose of 1 g may be sufficient and cost-effective, with fewer side effects than the higher dose. PMID- 30279134 TI - Anatomical analysis of the human ligamentum flavum in the thoracic spine: Clinical implications for posterior thoracic spinal surgery. AB - BACKGROUND: Knowledge of the ligamentum flavum anatomy is important for posterior spinal surgery. However, only a few studies have evaluated the relationship between the thoracic ligamentum flavum and its surrounding structures. This study aimed to clarify the anatomy of the thoracic ligamentum flavum. METHODS: The entire spines from 20 human embalmed cadavers were harvested in an en bloc fashion. All pedicles were vertically cut using a thread bone saw, and the ligamentum flavum from T1-T2 to T12-L1 was painted using a contrast agent containing an iron powder. Computed tomography was performed, and the ligamentum flavum shape (width and height) and its relationship with the spinal bony structures (lamina and foramen height percentage covered by the ligamentum flavum) were analyzed using a three-dimensional analyzing software. RESULTS: The thoracic ligamentum flavum height and width gradually increased from T1-T2 to T12 L1. The caudal lamina height ventrally covered by the ligamentum flavum also increased gradually from the upper (T1-T2: 31.7%) to the lower levels (T12-L1: 41.7%); however, the cranial lamina height dorsally covered by the ligamentum flavum decreased from the upper (12.6%) to the lower levels (4.3%). The neural foramen was covered by the ligamentum flavum in all thoracic spines, except for T1-T2. Between T2-T3 and T12-L1, approximately 50% of the cranial part of the foramens was covered by the ligamentum flavum; however, the caudal part was not covered. CONCLUSIONS: This study using contrasted ligamentum flavum and reconstructed CT provided information on the thoracic ligamentum flavum shape and its relationship with the bony structures. The ventral ligamentum flavum coverage of the cranial lamina increase from cranial to caudal, and the cranial half of the neural foramen is covered by the ligamentum flavum below T2-T3 but not in T1 T2. These findings would help spine surgeons to design and perform safe and adequate posterior thoracic spinal surgeries. PMID- 30279135 TI - Is metatarsus primus elevatus truly observed in hallux rigidus? Radiographic study using mapping methods. AB - BACKGROUND: Hallux rigidus and metatarsus primus elevatus (MPE) are associated, but their causal relationship remains unknown. Several surgical approaches for treating hallux rigidus are available. We evaluated morphological characteristics of hallux rigidus with different grades to determine the optimal surgical approach. The amount of degenerative change in the metatarsophalangeal joint on the preoperative roentgenograms was graded on a scale of 1-3. We analyzed the morphology of hallux rigidus using X-ray image mapping developed by our team. METHODS: This study involved weight-bearing, dorsoplantar, and lateral foot X rays of 36 feet from 26 patients underwent surgery for hallux rigidus (Group R) at our institution, and 26 normal feet (Group N). A two-dimensional coordinate system was used to analyze the sharps of these feet by converting each dot on the radiographs into X and Y coordinates. Diagrams of the feet from each group were drawn for comparison. Feet with grades 2 (Group R2) and 3 (Group R3) hallux rigidus and normal feet were compared by Kruskal-Wallis test. RESULTS: Mapping revealed that the tip of distal phalanges of the second, and third toes in Group R medially shifted (P < 0.05) in dorsoplantar image of the feet, and that the medial point, a part of the talus, navicular, cuneiform, and first metatarsal bone in Group R, shifted lower (P < 0.05) in lateral feet images of the feet. Multiple comparisons revealed a significant navicular bone depression in grade 3 hallux rigidus compared with normal feet. A significant difference was observed between Group N and R3 but not between Group R2 and N or R3. CONCLUSIONS: X-ray morphological analysis of the foot revealed MPE in Group R. Elevation gradually increased as hallux rigidus grade worsened. Therefore, osteotomy combined with cheilectomy, whereby the first metatarsal bone can be tilted toward the plantar side, are useful for treating a higher-grade hallux rigidus. LEVEL OF EVIDENCE: Level III, comparative study. PMID- 30279137 TI - Creating a Rural Surgery Track and a Review of Rural Surgery Training Programs. AB - OBJECTIVE: The objective of this study was to present the process of developing a rural surgery training track within an established residency program and review the current rural surgery training programs in the nation. DESIGN: This study reviews current rural surgery training opportunities at Accreditation Council for Graduate Medical Education accredited surgical residencies in the United States and presents the process of creating the University of Minnesota's rural surgery training track. SETTING: This study was performed at the University of Minnesota, in Minneapolis, Minnesota, and at Essentia Health-Saint Mary's Medical Center, in Duluth, Minnesota. PARTICIPANTS: Accredited general surgery residencies were reviewed. The creation of a designated rural surgery training track added an additional rural-designated surgical resident during each postgraduation year and created a required postgraduation year 2 rural surgery rotation for all categorical surgical residents. RESULTS: Two hundred sixty-eight surgery residency programs were reviewed. Twenty-seven had required rural rotations, 10 offered only elective rural rotations, and 4 had dedicated National Resident Matching Program codes for rural training tracks. After review of national rural surgery training opportunities, the University of Minnesota's process of creating a designated rural surgery training program required attention to 5 main components: needs assessment and review of local opportunities, surgery residency review committee approval, funding, surgical education, and clinical/operative education. CONCLUSIONS: Increasing opportunities for surgical residents to train in rural settings may help with recruitment of medical students and retention of surgeons pursuing careers in rural surgery. PMID- 30279138 TI - Involvement of released sphingosine 1-phosphate/sphingosine 1-phosphate receptor axis in skeletal muscle atrophy. AB - Skeletal muscle (SkM) atrophy is caused by several and heterogeneous conditions, such as cancer, neuromuscular disorders and aging. In most types of SkM atrophy overall rates of protein synthesis are suppressed, protein degradation is consistently elevated and atrogenes, such as the ubiquitin ligase Atrogin 1/MAFbx, are up-regulated. The molecular regulators of SkM waste are multiple and only in part known. Sphingolipids represent a class of bioactive molecules capable of modulating the destiny of many cell types, including SkM cells. In particular, we and others have shown that sphingosine 1phosphate (S1P), formed by sphingosine kinase (SphK), is able to act as trophic and morphogenic factor in myoblasts. Here, we report the first evidence that the atrophic phenotype observed in both muscle obtained from mice bearing the C26 adenocarcinoma and C2C12 myotubes treated with dexamethasone was characterized by reduced levels of active phospho-SphK1. The importance of SphK1 activity is also confirmed by the specific pharmacological inhibition of SphK1 able to increase Atrogin-1/MAFbx expression and reduce myotube size and myonuclei number. Furthermore, we found that SkM atrophy was accomplished by significant increase of S1P transporter Spns2 and in changes in the pattern of S1P receptor (S1PRs) subtype expression paralleled by increased Atrogin-1/MAFbx expression, suggesting a role for the released S1P and of specific S1PR-mediated signaling pathways in the control of the ubiquitin ligase. Altogether, these findings provide the first evidence that SphK1/released S1P/S1PR axis acts as a molecular regulator of SkM atrophy, thereby representing a new possible target for therapy in many patho physiological conditions. PMID- 30279136 TI - Decoding Cognitive Processes from Neural Ensembles. AB - An intrinsic difficulty in studying cognitive processes is that they are unobservable states that exist in between observable responses to the sensory environment. Cognitive states must be inferred from indirect behavioral measures. Neuroscience potentially provides the tools necessary to measure cognitive processes directly, but it is challenged on two fronts. First, neuroscientific measures often lack the spatiotemporal resolution to identify the neural computations that underlie a cognitive process. Second, the activity of a single neuron, which is the fundamental building block of neural computation, is too noisy to provide accurate measurements of a cognitive process. In this paper, I examine recent developments in neurophysiological recording and analysis methods that provide a potential solution to these problems. PMID- 30279139 TI - Mechanistic targeting of advanced glycation end-products in age-related diseases. AB - Glycative stress, caused by the accumulation of cytotoxic and irreversibly-formed sugar-derived advanced glycation end-products (AGEs), contributes to morbidity associated with aging, age-related diseases, and metabolic diseases. In this review, we summarize pathways leading to formation of AGEs, largely from sugars and glycolytic intermediates, and discuss detoxification of AGE precursors, including the glyoxalase system and DJ-1/Park7 deglycase. Disease pathogenesis downstream of AGE accumulation can be cell autonomous due to aggregation of glycated proteins and impaired protein function, which occurs in ocular cataracts. Extracellular AGEs also activate RAGE signaling, leading to oxidative stress, inflammation, and leukostasis in diabetic complications such as diabetic retinopathy. Pharmaceutical agents have been tested in animal models and clinically to diminish glycative burden. We summarize existing strategies and point out several new directions to diminish glycative stress including: plant derived polyphenols as AGE inhibitors and glyoxalase inducers; improved dietary patterns, particularly Mediterranean and low glycemic diets; and enhancing proteolytic capacities of the ubiquitin-proteasome and autophagy pathways that are involved in cellular clearing of AGEs. PMID- 30279140 TI - The GDF11-FTO-PPARgamma axis controls the shift of osteoporotic MSC fate to adipocyte and inhibits bone formation during osteoporosis. AB - During osteoporosis, the shift of bone mesenchymal stem cell (BMSC) lineage commitment to adipocyte leads to the imbalance between bone mass and fat, which increases the risk of fracture. The mechanism underlying this process is not fully understood. Fat mass and obesity-associated protein (FTO) is an RNA demethylase that demethylates various methylated nucleic acids and participates in various physiological and pathological processes. Here we identified FTO as a regulator for BMSC fate determination during osteoporosis. FTO was up-regulated in bone marrow during aging or osteoporosis in human and mice in a GDF11(growth differentiation factor 11)-C/EBPalpha-dependent mechanism. The expression of FTO was also up-regulated during adipocyte differentiation of BMSCs whereas its expression was down-regulated during osteoblast differentiation. Gain-of-function and loss-of-function experiments showed that FTO favored the BMSCs to differentiate to adipocytes rather than osteoblasts. Further mechanism study demonstrated that FTO bound and demethylated the mRNA of the Peroxisome proliferator-activated receptor gamma (Pparg), leading to the increase in the expression of Pparg mRNA. Reversely, Pparg knockdown blocked the function of GDF11-FTO during osteoblast differentiation of BMSCs. Furthermore, conditionally genetic knockout of Fto in osteoblasts inhibited the development of osteopenia in mice. Collectively, our findings demonstrated that GDF11-FTO-Pparg axis promoted the shift of osteoporotic BMSC fate to adipocyte and inhibited bone formation during osteoporosis.

PMID- 30279141 TI - Human rhomboid family-1 modulates clathrin coated vesicle-dependent pro transforming growth factor alpha membrane trafficking to promote breast cancer progression. AB - BACKGROUND: Epidermal growth factor receptor (EGFR) signalling is critical in epithelial cancer development. Human rhomboid family-1 (RHBDF1) facilitates the secretion of TGFalpha, an EGFR ligand, in breast cancer; however, the underlying mechanism remains unclear. We evaluated the role for RHBDF1 in clathrin-coated vesicle (CCV)-dependent pro-TGFalpha membrane trafficking in breast cancer cells upon stimulation by G-protein coupled receptor (GPCR) agonists. METHODS: RHBDF1 was silenced in various breast cancer cells using shRNA. TGFalpha levels, subcellular localization, and secretion were evaluated using ELISA, immunofluorescent staining, and coimmunoprecipitation. Phosphorylation and expression of relevant proteins were measured by western blotting. RHBDF1 dependent cell viability and invasion were measured. FINDINGS: RHBDF1 mediates GPCR agonist-induced EGFR phosphorylation by promoting TGFalpha secretion in various types of breast cancer cells. RHBDF1 not only mediates ADAM17-dependent shedding of TGFalpha, but is essential in membrane trafficking of pro-TGFalpha. RHBDF1 silencing results in blocking of clathrin uncoating from CCV, a crucial step for the plasma membrane release of pro-TGFalpha. Interaction of RHBDF1 with auxilin-2, a CCV protein, determines the recruitment of HSC70 to CCV to facilitate clathrin uncoating. RHBDF1 function is required for the proliferation and mobility of breast cancer cells upon stimulation by Sphingosine 1 Phosphate (S1P), a GPCR agonist. We demonstrate a significant correlation between RHBDF1 overexpression and EGFR activation in breast cancer tissues. INTERPRETATION: RHBDF1 is an indispensable component of the protein trafficking machinery involved in GPCR-mediated EGFR transactivation, and is an attractive therapeutic target for cancer.

PMID- 30279145 TI - Detection and quantitation of iron in ferritin, transferrin and labile iron pool (LIP) in cardiomyocytes using 55Fe and storage phosphorimaging. AB - Dysregulated iron metabolism has a detrimental effect on cardiac function. The importance of iron homeostasis in cardiac health and disease warrants detailed studies of cardiomyocyte iron uptake, utilization and recycling at the molecular level. In this study, we have performed metabolic labeling of primary cultures of neonatal rat cardiomyocytes with radioactive iron coupled with separation of labeled iron-containing molecules by native electrophoresis followed by detection and quantification of incorporated radioiron by storage phosphorimaging. For the radiolabeling we used a safe and convenient beta emitter 55Fe which enabled sensitive and simultaneous detection and quantitation of iron in cardiomyocyte ferritin, transferrin and the labile iron pool (LIP). The LIP is believed to represent potentially dangerous redox-active iron bound to uncharacterized molecules. Using size-exclusion chromatography spin micro columns, we demonstrate that iron in the LIP is bound to high molecular weight molecule(s) (>=5000 Da) in the neonatal cardiomyocytes. PMID- 30279144 TI - SIRT5 deacylates metabolism-related proteins and attenuates hepatic steatosis in ob/ob mice. AB - BACKGROUND: Sirtuin 5 (SIRT5) is a NAD+-dependent lysine deacylase. The SIRT5 deficiency mouse model shows that it is dispensable for metabolic homeostasis under normal conditions. However, the biological role of SIRT5 and acylation in pathological states such as obesity and type 2 diabetes (T2D) remains elusive. METHODS: The hepatic SIRT5-overexpressing ob/ob mouse model (ob/ob-SIRT5 OE) was established by CRISPR/Cas9 gene editing tool Protein malonylation and succinylation lysine sites were identified by immunoprecipitation coupled lipid chromatography - tandem mass spectrometry (LC-MS/MS) methods. FINDINGS: The ob/ob SIRT5 OE mice showed decreased malonylation and succinylation, improved cellular glycolysis, suppressed gluconeogenesis, enhanced fatty acid oxidation, and attenuated hepatic steatosis. A total of 955 malonylation sites on 434 proteins and 1377 succinylation sites on 429 proteins were identified and quantitated. Bioinformatics analysis revealed that malonylation was the major SIRT5 target in the glycolysis/gluconeogenesis pathway, whereas succinylation was the preferred SIRT5 target in the oxidative phosphorylation pathway. INTERPRETATION: Hepatic overexpression of SIRT5 ameliorated the metabolic abnormalities of ob/ob mice, probably through demalonylating and desuccinylating proteins in the main metabolic pathways. SIRT5 and related acylation might be potential targets for metabolic disorders.

PMID- 30279147 TI - Genetically encoded fluorescent indicators for live cell pH imaging. AB - BACKGROUND: Intracellular pH underlies most cellular processes. There is emerging evidence of a pH-signaling role in plant cells and microorganisms. Dysregulation of pH is associated with human diseases, such as cancer and Alzheimer's disease. SCOPE OF REVIEW: In this review, we attempt to provide a summary of the progress that has been made in the field during the past two decades. First, we present an overview of the current state of the design and applications of fluorescent protein (FP)-based pH indicators. Then, we turn our attention to the development and applications of hybrid pH sensors that combine the capabilities of non-GFP fluorophores with the advantages of genetically encoded tags. Finally, we discuss recent advances in multicolor pH imaging and the applications of genetically encoded pH sensors in multiparameter imaging. MAJOR CONCLUSIONS: Genetically encoded pH sensors have proven to be indispensable noninvasive tools for selective targeting to different cellular locations. Although a variety of genetically encoded pH sensors have been designed and applied at the single cell level, there is still much room for improvements and future developments of novel powerful tools for pH imaging. Among the most pressing challenges in this area is the design of brighter redshifted sensors for tissue research and whole animal experiments. GENERAL SIGNIFICANCE: The design of precise pH measuring instruments is one of the important goals in cell biochemistry and may give rise to the development of new powerful diagnostic tools for various diseases. PMID- 30279146 TI - Dependence of HSP27 cellular level on protein kinase CK2 discloses novel therapeutic strategies. AB - BACKGROUND: HSP27 plays a role in various diseases, including neurodegenerative diseases, ischemia, and atherosclerosis. It is particularly important in the regulation of the development, progression and metastasis of cancer as well as cell apoptosis and drug resistance. However, the absence of an ATP binding domain, that is, instead, present in other HSPs such as HSP90 and HSP70, hampers the development of small molecules as inhibitors of HSP27. METHODS: Knockout cell lines generated by Crispr/Cas9 gene editing tool, specific kinase inhibitors and siRNA transfections were exploited to demonstrate that the expression of HSP27 is dependent on the integrity/activity of protein kinase CK2 holoenzyme. The interaction between these proteins has been confirmed by co-immunoprecipitation, confocal immunofluorescence microscopy, and by density gradient separation of protein complexes. Finally, using a proliferation assay this study demonstrates the potential efficacy of a combinatory therapy of heath shock and CK2 inhibitors in cancer treatment. RESULTS: Our data demonstrate that CK2 is able to regulate HSP27 turnover by affecting the expression of its ubiquitin ligase SMURF2 (Smad ubiquitination regulatory factor 2). Moreover, for the first time we show an increased sensitivity of CK2-inhibited tumour cells to hyperthermia treatment. CONCLUSION: Being HSP27 involved in several pathological conditions, including protein conformational diseases (i.e Cystic Fibrosis) and cancer, the need of drugs to modulate its activity is growing and CK2-targeting could represent a new strategy to reduce cellular HSP27 level. GENERAL SIGNIFICANCE: This study identifies CK2 as a molecular target to control HSP27 cellular expression. PMID- 30279143 TI - Fisetin is a senotherapeutic that extends health and lifespan. AB - BACKGROUND: Senescence is a tumor suppressor mechanism activated in stressed cells to prevent replication of damaged DNA. Senescent cells have been demonstrated to play a causal role in driving aging and age-related diseases using genetic and pharmacologic approaches. We previously demonstrated that the combination of dasatinib and the flavonoid quercetin is a potent senolytic improving numerous age-related conditions including frailty, osteoporosis and cardiovascular disease. The goal of this study was to identify flavonoids with more potent senolytic activity. METHODS: A panel of flavonoid polyphenols was screened for senolytic activity using senescent murine and human fibroblasts, driven by oxidative and genotoxic stress, respectively. The top senotherapeutic flavonoid was tested in mice modeling a progeroid syndrome carrying a p16INK4a luciferase reporter and aged wild-type mice to determine the effects of fisetin on senescence markers, age-related histopathology, disease markers, health span and lifespan. Human adipose tissue explants were used to determine if results translated. FINDINGS: Of the 10 flavonoids tested, fisetin was the most potent senolytic. Acute or intermittent treatment of progeroid and old mice with fisetin reduced senescence markers in multiple tissues, consistent with a hit-and-run senolytic mechanism. Fisetin reduced senescence in a subset of cells in murine and human adipose tissue, demonstrating cell-type specificity. Administration of fisetin to wild-type mice late in life restored tissue homeostasis, reduced age related pathology, and extended median and maximum lifespan. INTERPRETATION: The natural product fisetin has senotherapeutic activity in mice and in human tissues. Late life intervention was sufficient to yield a potent health benefit. These characteristics suggest the feasibility to translation to human clinical studies.

PMID- 30279149 TI - Quantifying codon usage in signal peptides: Gene expression and amino acid usage explain apparent selection for inefficient codons. AB - The Sec secretion pathway is found across all domains of life. A critical feature of Sec secreted proteins is the signal peptide, a short peptide with distinct physicochemical properties located at the N-terminus of the protein. Previous work indicates signal peptides are biased towards translationally inefficient codons, which is hypothesized to be an adaptation driven by selection to improve the efficacy and efficiency of the protein secretion mechanisms. We investigate codon usage in the signal peptides of E. coli using the Codon Adaptation Index (CAI), the tRNA Adaptation Index (tAI), and the ribosomal overhead cost formulation of the stochastic evolutionary model of protein production rates (ROC SEMPPR). Comparisons between signal peptides and 5'-end of cytoplasmic proteins using CAI and tAI are consistent with a preference for inefficient codons in signal peptides. Simulations reveal these differences are due to amino acid usage and gene expression - we find these differences disappear when accounting for both factors. In contrast, ROC-SEMPPR, a mechanistic population genetics model capable of separating the effects of selection and mutation bias, shows codon usage bias (CUB) of the signal peptides is indistinguishable from the 5'-ends of cytoplasmic proteins. Additionally, we find CUB at the 5'-ends is weaker than later segments of the gene. Results illustrate the value in using models grounded in population genetics to interpret genetic data. We show failure to account for mutation bias and the effects of gene expression on the efficacy of selection against translation inefficiency can lead to a misinterpretation of codon usage patterns. PMID- 30279148 TI - Myrtenal-induced V-ATPase inhibition - A toxicity mechanism behind tumor cell death and suppressed migration and invasion in melanoma. AB - BACKGROUND: Metastatic tumor cells have acidic extracellular pH and differential electrochemical H+ gradients generated across their cell membranes by V-type H+ ATPases. This study shows that inhibition of the V-ATPases by the plant-derived monoterpene Myrtenal results in tumor cell death and decreased metastatic dissemination in mice. METHODS: The Myrtenal anticancer toxicity was evaluated in vitro using murine (B16F0 and B16F10) and human (SkMel-5) melanoma cell lines, and in in vivo mouse metastatic dissemination model. Proton flux and extracellular acidification were directly evaluated at the surface of living cells using a non-invasive selective ion electrode approach. RESULTS: The inhibition of V-ATPases by 100 MUM Myrtenal disrupted the electrochemical H+ gradient across the cell membranes, strongly induced cell death (4-5 fold), and decreased tumor cells migration and invasion in vitro. Myrtenal (15 mg/kg) also significantly reduced metastasis induced by B16F10 in vivo, further reinforcing that V-ATPase is a molecular target to halt the progression of cancers. CONCLUSIONS: These data revealed the therapeutic potential of Myrtenal as inhibitor of melanoma progression proposing a mechanism of action by which once inhibited by this monoterpene the proton pumps fail to activate cancer-related differential electrochemical gradients and H+ fluxes across the tumor cell membranes, disrupting pH signatures inherent in tumor progression, resulting in reprogrammed cell death and metastasis inhibition. GENERAL SIGNIFICANCE: The work represents a new mechanistic strategy for contention of melanoma, the most aggressive and deadly form of cutaneous neoplasm, and highlights Myrtenal, other related monoterpenes and derivatives as promising proton pump inhibitors with high chemotherapeutic potential. PMID- 30279150 TI - Probing the effect of membrane contents on transmembrane protein-protein interaction using solution NMR and computer simulations. AB - The interaction between the secondary structure elements is the key process, determining the spatial structure and activity of a membrane protein. Transmembrane (TM) helix-helix interaction is known to be especially important for the function of so-called type I or bitopic membrane proteins. In the present work, we present the approach to study the helix-helix interaction in the TM domains of membrane proteins in various lipid environment using solution NMR spectroscopy and phospholipid bicelles. The technique is based on the ability of bicelles to form particles with the size, depending on the lipid/detergent ratio. To implement the approach, we report the experimental parameters of "ideal bicelle" models for four kinds of zwitterionic phospholipids, which can be also used in other structural studies. We show that size of bicelles and type of the rim-forming detergent do not affect substantially the spatial structure and stability of the model TM dimer. On the other hand, the effect of bilayer thickness on the free energy of the dimer is dramatic, while the structure of the protein is unchanged in various lipids with fatty chains having a length from 12 to 18 carbon atoms. The obtained data is analyzed using the computer simulations to find the physical origin of the observed effects. PMID- 30279152 TI - Antimicrobial peptides from C-terminal amphipathic region of E. coli FtsA. AB - Antimicrobial peptides constitute an indispensable component of innate immune system in organisms ranging from bacteria to man. Despite this, peptides lag far behind the conventional antibiotics in treating infections. The menace of multidrug-resistant bacteria, however, has revived the antimicrobial peptide research. We reasoned that the membrane-binding regions of bacterial proteins could be purposed to combat them. Here, we identify potent antimicrobial peptides from the C-terminal amphipathic helix of E. coli FtsA protein. The 11 and 13 residue peptides exhibited activity against E. coli, gentamicin-resistant MRSA, and C. albicans. The activity is little affected by the presence of salt and divalent cations. The peptides preferentially bind to the negatively-charged membranes as indicated by tryptophan fluorescence studies. The peptides permeabilize the E. coli outer and inner membranes at very promising concentrations suggesting membrane-disruption as one of the mechanisms of killing. PMID- 30279151 TI - Intercellular communication via gap junction channels between chondrocytes and bone cells. AB - Cell-to-cell communication between bone, cartilage and the synovial membrane is not fully understood and it is only attributed to the diffusion of substances through the extracellular space or synovial fluid. In this study, we found for the first time that primary bone cells (BCs) including osteocytes, synovial cells (SCs) and chondrocytes (CHs) are able to establish cellular contacts and to couple through gap junction (GJ) channels with connexin43 (Cx43) being dominant. Transwell co-culture and identification by mass spectrometry revealed the exchange of essential amino acids, peptides and proteins including calnexin, calreticulin or CD44 antigen between contacting SCs, BCs and CHs. These results reveal that CHs, SCs and BCs are able to establish intercellular connections and to communicate through GJ channels, which provide a selective signalling route by the direct exchange of potent signalling molecules and metabolites. PMID- 30279153 TI - Transmission of IMI-2 carbapenemase-producing Enterobacteriaceae from river water to human. AB - OBJECTIVES: Carbapenemase-producing Enterobacteriaceae (CPE) are increasing worldwide in human infections. The role of rivers as reservoirs is highlighted, but transmission from the environment to humans is not documented. A human case of bacteraemia caused by IMI-2 carbapenemase-producing Enterobacter asburiae following massive river water exposure underwent microbiological investigations with the aim of deciphering the origin and mechanism of infection. METHODS: Clinical and environmental bacterial strains were compared by resistotyping and genomotyping using pulsed-field gel electrophoresis (PFGE). PFGE was also used to determine the location of the blaIMI-2 carbapenemase gene. The patient's microbiota and river bacterial communities were compared by fingerprinting using 16S rRNA gene PCR-temporal temperature gel electrophoresis. RESULTS: Enterobacter asburiae causing bacteraemia carried the same plasmidic blaIMI-2 gene as E. asburiae strains detected in river water 1 month later. Clinical and river strains displayed identical PFGE profiles. Community fingerprinting showed the persistence in the patient's microbiota of carbapenem-resistant bacteria, which were also autochthonous in the river community (E. asburiae, Aeromonas veronii and Pseudomonas fluorescens). CONCLUSION: Here we have identified for the first time the presence of an IMI-2-producing E. asburiae in a river in the South of France and suggest transmission from the river to a human probably following intestinal translocation. General insights into transmission of CPE from the environment to humans are gained from this case. Considering the rapid spread of CPE in humans, the risk of transfer from an environmental reservoir to human microbiota should be thoroughly investigated at least by implementing environmental surveillance of carbapenem resistance. PMID- 30279154 TI - Supported Internet-Delivered Cognitive Behavior Treatment for Adults with Severe Depressive Symptoms: A Secondary Analysis. AB - BACKGROUND: Depression is a highly prevalent mental health issue that exacts significant economic, societal, personal, and interpersonal costs. Innovative internet-delivered interventions have been designed to increase accessibility to and cost-effectiveness of treatments. These treatments have mainly targeted mild to moderate levels of depression. The increased risk associated with severe depression, particularly of suicidal ideation often results in this population being excluded from research studies. As a result, the effectiveness of internet delivered cognitive behavioral therapy (iCBT) in more severely depressed cohorts is less researched. OBJECTIVE: The aim of this study is to examine the effect of iCBT on symptoms of severe depression, comorbid symptoms of anxiety, and levels of work and social functioning. METHODS: Retrospective consent was provided by participants with elevated scores (>28 severe depression symptoms) on the Beck Depression Inventory (BDI-II) who accessed an iCBT intervention (Space from Depression) with support for up to 8 weeks. Data were collected at baseline, posttreatment, and 3-month follow-up on the primary outcome (BDI-II), and secondary outcomes (the Generalized Anxiety Disorder-7 and the Work and Social Adjustment Scale). RESULTS: A significant change was observed on all measures between pre- and postmeasurement and maintained at 3-month follow-up. Clinical improvement was observed for participants on the BDI-II from pre- to postmeasurement, and suicidal ideation also reduced from pre- to postmeasurement. CONCLUSIONS: Users of Space from Depression with symptoms of severe depression were found to have decreased symptoms of depression and anxiety and increased levels of work and social functioning. The intervention also demonstrated its potential to decrease suicidal ideation. Further investigation is required to determine why some individuals improve, and others do not. iCBT may have the potential to be used as an adjunct treatment for severe depression symptoms, but participants may require further treatment if they receive iCBT as a standalone intervention. Although promising, further research incorporating control groups is needed to support the utility of Space from Depression for use in or as an adjunct to treatment for severe depression. PMID- 30279156 TI - Palivizumab for all children with Down syndrome? PMID- 30279155 TI - Proposing a Transactional Model of eHealth Literacy: Concept Analysis. AB - BACKGROUND: Electronic health (eHealth) literacy was conceptualized in 2006 as the ability of internet users to locate, evaluate, and act upon web-based health information. Now, advances in eHealth technology have cultivated transactional opportunities for patients to access, share, and monitor health information. However, empirical evidence shows that existing models and measures of eHealth literacy have limited theoretical underpinnings that reflect the transactional capabilities of eHealth. This paper describes a conceptual model based on the Transactional Model of Communication (TMC), in which eHealth literacy is described as an intrapersonal skillset hypothesized as being dynamic; reciprocal; and shaped by social, relational, and cultural contexts. OBJECTIVE: The objective of our study was to systematically examine eHealth literacy definitions, models, and measures to propose a refined conceptual and operational definition based on the TMC. METHODS: Walker and Avant's concept analysis method was used to guide the systematic review of eHealth literacy definitions (n=10), rating scales (n=6), models (n=4), and peer-reviewed model applications (n=16). Subsequent cluster analyses showed salient themes across definitions. Dimensions, antecedents, and consequences reflected in models and measures were extracted and deductively analyzed based on codes consistent with the TMC. RESULTS: Systematic review evidence revealed incongruity between operational eHealth literacy included in definitions compared with literacies included within models and measures. Theoretical underpinnings of eHealth literacy also remain dismal. Despite the transactional capabilities of eHealth, the role of "communication" in eHealth literacy remains underdeveloped and does not account for physical and cognitive processing abilities necessary for multiway transactions. CONCLUSIONS: The Transactional Model of eHealth Literacy and a corresponding definition are proposed. In this novel model, eHealth literacy comprises a hierarchical intrapersonal skillset that mediates the reciprocal effect of contextual factors (ie, user oriented and task oriented) on patient engagement in health care. More specifically, the intrapersonal skillset counteracts the negative effect of "noise" (or impediments) produced by social and relational contexts. Cutting across health and technology literacies, the intrapersonal skillset of eHealth literacy is operationalized through four literacies that correspond with discrete operative skills: (1) functional (ie, locate and understand); (2) communicative (ie, exchange); (3) critical (ie, evaluate); and (4) translational (ie, apply). PMID- 30279158 TI - Causes and characteristics of injury in paediatric major trauma and trends over time. AB - OBJECTIVE: To investigate causes, characteristics and temporal trends of paediatric major trauma. DESIGN: A retrospective review of paediatric major trauma (<16 years of age) was conducted using data from the population-based Victorian State Trauma Registry from 2006 to 2016. Temporal trends in population based incidence rates were evaluated using Poisson regression. SETTING: Victoria, Australia. RESULTS: Of the 1511 paediatric major trauma patients, most were male (68%), had sustained blunt trauma (87%) and had injuries resulting from unintentional events (91%). Motor vehicle collisions (15%), struck by/collisions with an object or person (14%) and low falls (13%) were the leading mechanisms of injury. Compared with those aged 1-15 years, a greater proportion of non accidental injury events were observed in infants (<1 year) (32%). For all patients, isolated head injury (29%), other/multitrauma (27%) and head and other injuries (24%) were the most prevalent injury groups. The incidence of paediatric major trauma did not change over the study period (incidence rate ratio (IRR)=0.97; 95% CI 0.92 to 1.02; p=0.27), which was consistent in all age groups. There was a 3% per year decline in the incidence of transport events (IRR=0.97; 95% CI 0.94 to 0.99; p=0.005), but no change in the incidence of falls of any type (IRR=1.01; 95% CI 0.97 to 1.04; p=0.70) or other events (IRR=1.00; 95% CI 0.97 to 1.02; p=0.79). The overall in-hospital mortality rate was 7.2%. CONCLUSIONS: This study demonstrated no change in the incidence of paediatric major trauma over an 11-year period. Given the potential lifelong impacts of serious injury in children, additional investment and coordination of injury prevention activities are required.

AB - Researchers are extensively searching for modifiable risk factors including high risk medications such as anticoagulation to avoid rehospitalisation. The influence of oral anticoagulant therapy on hospital readmission is not known. We investigated the impact of warfarin and direct oral anticoagulants (DOACs) on all cause 30-day hospital readmission retrospectively in an academic centre. We study the eligible cohort of 1781 discharges over 2-year period. Data on age, gender, diagnoses, 30-day hospital readmission, discharge medications and variables in the HOSPITAL score (Haemoglobin level at discharge, Oncology at discharge, Sodium level at discharge, Procedure during hospitalisation, Index admission, number of hospital Admissions, Length of stay) and LACE index (Length of stay, Acute/emergent admission, Charlson comorbidity index score, Emergency department visits in previous 6 months), which have higher predictability for readmission were extracted and matched for analysis. Warfarin was the most common anticoagulant prescribed at discharge (273 patients) with a readmission rate of 20% (p<0.01). DOACs were used by 94 patients at discharge with a readmission rate of 4% (p=0.219). Multivariate logistic regression showed an increased risk of readmission with warfarin therapy (OR 1.36, p=0.045). Logistic regression did not show DOACs to be a risk factor for hospital readmission. Our data suggests that warfarin therapy is a risk factor for all-cause 30-day hospital readmission. DOAC therapy is not found to be associated with a higher risk of hospital readmission. Warfarin anticoagulation may be an important target for interventions to reduce hospital readmissions. PMID- 30279161 TI - Preproglucagon Neurons in the Nucleus of the Solitary Tract are the Main Source of Brain GLP-1, Mediate Stress-Induced Hypophagia, and Limit Unusually Large Intakes of Food. AB - Centrally administered glucagon-like peptide-1 (GLP-1) supresses food intake. Here we demonstrate that GLP-1-producing (PPG) neurons in the nucleus tractus solitarii (NTS) are the predominant source of endogenous GLP-1 within the brain. Selective ablation of NTS PPG neurons by viral expression of diphtheria toxin subunit A (DTA) substantially reduced active GLP-1 concentrations in brain and spinal cord. Contrary to expectations, this loss of central GLP-1 had no significant effect on ad libitum feeding of mice, affecting neither daily chow intake nor body weight or glucose tolerance. Only after bigger challenges to homeostasis were PPG neurons necessary for food intake control. PPG-ablated mice increased food intake following a prolonged fast and after a liquid diet preload. Consistent with our ablation data, acute inhibition of hM4Di-expressing PPG neurons did not affect ad libitum feeding, however, it increased post-fast refeeding intake and blocked stress-induced hypophagia. Additionally, chemogenetic PPG neuron activation through hM3Dq caused a strong acute anorectic effect. We conclude that PPG neurons are not involved in primary intake regulation, but form part of a secondary satiation/satiety circuit, activated by both psychogenic stress and large meals. Given their hypophagic capacity, PPG neurons might be an attractive drug target in obesity treatment. PMID- 30279163 TI - Pygo2 Regulates Adiposity and Glucose Homeostasis via beta-Catenin-Axin2-GSK3beta Signaling Pathway. AB - Wnt/beta-catenin signaling plays a key role in regulating adipogenesis through indirectly inhibiting the expression of C/EBPalpha and peroxisome proliferator activated receptor gamma (PPARgamma); however, the detailed molecular mechanism remains poorly understood. Moreover, the factor(s) that determines the Wnt/beta catenin output level during adipogenesis is also not completely defined. In this study, we showed that Pygo2 exhibited a declined expression pattern during adipocyte differentiation, resulting in an attenuated Wnt/beta-catenin output level. The mechanism study indicated that Pygo2 inhibition led to the downregulation of Axin2, a constitutive Wnt target, in the cytoplasm. Consequently, Axin2-bound GSK3beta was released and translocated into the nucleus to phosphorylate C/EBPbeta and Snail, resulting in an increase in the DNA binding activity of C/EBPbeta and decreased protein stability of Snail, which subsequently activated the expression of C/EBPalpha and PPARgamma. Consistent with this, embryonic fibroblasts from Pygo2-/- mice exhibited spontaneous adipocyte differentiation, and adipocyte precursor-specific Pygo2-deficient mice exhibited increased adiposity with decreased energy expenditure. We further showed impaired glucose tolerance and decreased systemic insulin sensitivity in Pygo2-deficient mice. Our study revealed an association between Pygo2 function and obesity or diabetes.

We show that expression of the miR-199a/214 cluster is dramatically decreased during brown and beige adipocyte differentiation and in response to cold exposure or beta-adrenergic receptor activation. The cluster levels are significantly upregulated in the adipose tissues of obese mice and human subjects. Overexpression of the miR-199a/214 cluster suppresses brown adipocyte differentiation and inhibits thermogenic gene expression and mitochondrial respiration, whereas knockdown of the cluster increases thermogenic gene expression and mitochondrial function in beige adipocytes. In addition, inhibition of the miR-199a/214 cluster promotes beiging effects in vivo. We further show that miR-199a/214 suppresses brown adipocyte differentiation and beige fat development by directly targeting PRDM16 and peroxisome PGC-1alpha, two key transcriptional regulators of adipose browning. Together, these observations reveal that the miR-199a/214 cluster is a key negative regulator of brown and beige fat development and thermogenesis. PMID- 30279157 TI - Research priorities for childhood chronic conditions: a workshop report. AB - BACKGROUND: Chronic conditions are the leading cause of mortality, morbidity and disability in children. However, children and caregivers are rarely involved in identifying research priorities, which may limit the value of research in supporting patient-centred practice and policy. OBJECTIVE: To identify priorities of patients, caregivers and health professionals for research in childhood chronic conditions and describe the reason for their choices. SETTING: An Australian paediatric hospital and health consumer organisations. METHODS: Recruited participants (n=73) included patients aged 8 to 14 years with a chronic condition (n=3), parents/caregivers of children aged 0 to 18 years with a chronic condition (n=19), representatives from consumer organisations (n=13) and health professionals including clinicians, researches (n=38) identified and discussed research priorities. Transcripts were thematically analysed. RESULTS: Seventy eight research questions were identified. Five themes underpinned participants' priorities: maintaining a sense of normality (enabling participation in school, supporting social functioning, promoting understanding and acceptance), empowering self-management and partnership in care (overcoming communication barriers, gaining knowledge and skills, motivation for treatment adherence, making informed decisions, access and understanding of complementary and alternative therapies),strengthening ability to cope (learning to have a positive outlook, preparing for home care management, transitioning to adult services), broadening focus to family (supporting sibling well-being, parental resilience and financial loss, alleviating caregiver burden), and improving quality and scope of health and social care (readdressing variability and inequities, preventing disease complications and treatment side effects, identifying risk factors, improving long-term outcomes, harnessing technology, integrating multidisciplinary services). CONCLUSION: Research priorities identified by children, caregivers and health professionals emphasise a focus on life participation, psychosocial well-being, impact on family and quality of care. These priorities may be used by funding and policy organisations in establishing a paediatric research agenda. PMID- 30279165 TI - Impact of automated photo enforcement of vehicle speed in school zones: interrupted time series analysis. AB - OBJECTIVE: Measure the impact of automated photo speed enforcement in school zones on motorist speed and speeding violation rates during school travel. METHODS: Automated enforcement cameras, active during school commuting hours, were installed around four elementary schools in Seattle, Washington, USA in 2012. We examined the effect of automated enforcement on motorist speeds and speed violation rates during the citation period (10 December 2012 to 15 January 2015) compared with the 'warning' period (1 November to 9 December 2012). We evaluated outcomes with an interrupted time series approach using multilevel mixed linear regression. RESULTS: Motorist speed violation rates decreased by nearly half in the citation period compared with the warning period (standardised incident rate ratio 0.53, 95% CI 0.42 to 0.66). The hourly maximum violation speed and mean hourly speeds decreased 2.1 MPH (95% CI -2.88 to -1.39) and 1.1 MPH (95% CI -1.64 to - 0.60), respectively. The impact of automated enforcement was sustained during the second year of implementation. CONCLUSION: Automated photo enforcement of speed limit in school zones was effective at reducing motorist speed violations and also achieved a significant reduction in mean motorist speed.

AB - Inadequate tissue oxygen, or hypoxia, is a central concept in the pathophysiology of ischemic disorders and cancer. Hypoxia promotes extracellular matrix (ECM) remodeling, cellular metabolic adaptation, and cancer cell metastasis. To discover new pathways through which cells respond to hypoxia, we performed a large-scale forward genetic screen in Caenorhabditis elegans and identified a previously uncharacterized receptor tyrosine kinase named HIR-1. Loss of function in hir-1 phenocopied the impaired ECM integrity associated with hypoxia or deficiency in the oxygen-dependent dual oxidase, heme peroxidases, or cuticular collagens involved in ECM homeostasis. Genetic suppressor screens identified NHR 49 and MDT-15 as transcriptional regulators downstream of HIR-1. Furthermore, hir 1 mutants showed defects in adapting to and recovering from prolonged severe hypoxia. We propose that C. elegans HIR-1 coordinates hypoxia-inducible factor independent responses to hypoxia and hypoxia-associated ECM remodeling through mechanisms that are likely conserved in other organisms. PMID- 30279162 TI - FOXO1 Deletion Reverses the Effect of Diabetic-Induced Impaired Fracture Healing. AB - Type 1 diabetes impairs fracture healing. We tested the hypothesis that diabetes affects chondrocytes to impair fracture healing through a mechanism that involves the transcription factor FOXO1. Type 1 diabetes was induced by streptozotocin in mice with FOXO1 deletion in chondrocytes (Col2alpha1Cre+FOXO1L/L) or littermate controls (Col2alpha1Cre-FOXO1L/L) and closed femoral fractures induced. Diabetic mice had 77% less cartilage and 30% less bone than normoglycemics evaluated histologically and by micro-computed tomography. Both were reversed with lineage specific FOXO1 ablation. Diabetic mice had a threefold increase in osteoclasts and a two- to threefold increase in RANKL mRNA or RANKL-expressing chondrocytes compared with normoglycemics. Both parameters were rescued by FOXO1 ablation in chondrocytes. Conditions present in diabetes, high glucose (HG), and increased advanced glycation end products (AGEs) stimulated FOXO1 association with the RANKL promoter in vitro, and overexpression of FOXO1 increased RANKL promoter activity in luciferase reporter assays. HG and AGE stimulated FOXO1 nuclear localization, which was reversed by insulin and inhibitors of TLR4, histone deacetylase, nitric oxide, and reactive oxygen species. The results indicate that chondrocytes play a prominent role in diabetes-impaired fracture healing and that high levels of glucose, AGEs, and tumor necrosis factor-alpha, which are elevated by diabetes, alter RANKL expression in chondrocytes via FOXO1. PMID- 30279167 TI - The LKB1-AMPK-alpha1 signaling pathway triggers hypoxic pulmonary vasoconstriction downstream of mitochondria. AB - Hypoxic pulmonary vasoconstriction (HPV), which aids ventilation-perfusion matching in the lungs, is triggered by mechanisms intrinsic to pulmonary arterial smooth muscles. The unique sensitivity of these muscles to hypoxia is conferred by mitochondrial cytochrome c oxidase subunit 4 isoform 2, the inhibition of which has been proposed to trigger HPV through increased generation of mitochondrial reactive oxygen species. Contrary to this model, we have shown that the LKB1-AMPK-alpha1 signaling pathway is critical to HPV. Spectral Doppler ultrasound revealed that deletion of the AMPK-alpha1 catalytic subunit blocked HPV in mice during mild (8% O2) and severe (5% O2) hypoxia, whereas AMPK-alpha2 deletion attenuated HPV only during severe hypoxia. By contrast, neither of these genetic manipulations affected serotonin-induced reductions in pulmonary vascular flow. HPV was also attenuated by reduced expression of LKB1, a kinase that activates AMPK during energy stress, but not after deletion of CaMKK2, a kinase that activates AMPK in response to increases in cytoplasmic Ca2+ Fluorescence imaging of acutely isolated pulmonary arterial myocytes revealed that AMPK-alpha1 or AMPK-alpha2 deletion did not affect mitochondrial membrane potential during normoxia or hypoxia. However, deletion of AMPK-alpha1, but not of AMPK-alpha2, blocked hypoxia from inhibiting KV1.5, the classical "oxygen-sensing" K+ channel in pulmonary arterial myocytes. We conclude that LKB1-AMPK-alpha1 signaling pathways downstream of mitochondria are critical for the induction of HPV, in a manner also supported by AMPK-alpha2 during severe hypoxia. PMID- 30279168 TI - Soluble gp130 prevents interleukin-6 and interleukin-11 cluster signaling but not intracellular autocrine responses. AB - Interleukin-6 (IL-6) is a proinflammatory cytokine of the IL-6 family, members of which signal through a complex of a cytokine-specific receptor and the signal transducing subunit gp130. The interaction of IL-6 with the membrane-bound IL-6 receptor (IL-6R) and gp130 stimulates "classic signaling," whereas the binding of IL-6 and a soluble version of the IL-6R to gp130 stimulates "trans-signaling." Alternatively, "cluster signaling" occurs when membrane-bound IL-6:IL-6R complexes on transmitter cells activate gp130 receptors on neighboring receiver cells. The soluble form of gp130 (sgp130) is a selective trans-signaling inhibitor, but it does not affect classic signaling. We demonstrated that the interaction of soluble gp130 with natural and synthetic membrane-bound IL-6:IL-6R complexes inhibited IL-6 cluster signaling. Similarly, IL-11 cluster signaling through the IL-11R to gp130 was also inhibited by soluble gp130. However, autocrine classic and trans-signaling was not inhibited by extracellular inhibitors such as sgp130 or gp130 antibodies. Together, our results suggest that autocrine IL-6 signaling may occur intracellularly. PMID- 30279170 TI - Sixty seconds on . . . monkeypox. PMID- 30279169 TI - The bacterial Ras/Rap1 site-specific endopeptidase RRSP cleaves Ras through an atypical mechanism to disrupt Ras-ERK signaling. AB - The Ras-extracellular signal-regulated kinase pathway is critical for controlling cell proliferation, and its aberrant activation drives the growth of various cancers. Because many pathogens produce toxins that inhibit Ras activity, efforts to develop effective Ras inhibitors to treat cancer could be informed by studies of Ras inhibition by pathogens. Vibrio vulnificus causes fatal infections in a manner that depends on multifunctional autoprocessing repeats-in-toxin, a toxin that releases bacterial effector domains into host cells. One such domain is the Ras/Rap1-specific endopeptidase (RRSP), which site-specifically cleaves the Switch I domain of the small GTPases Ras and Rap1. We solved the crystal structure of RRSP and found that its backbone shares a structural fold with the EreA/ChaN-like superfamily of enzymes. Unlike other proteases in this family, RRSP is not a metalloprotease. Through nuclear magnetic resonance analysis and nucleotide exchange assays, we determined that the processing of KRAS by RRSP did not release any fragments or cause KRAS to dissociate from its bound nucleotide but instead only locally affected its structure. However, this structural alteration of KRAS was sufficient to disable guanine nucleotide exchange factor mediated nucleotide exchange and prevent KRAS from binding to RAF. Thus, RRSP is a bacterial effector that represents a previously unrecognized class of protease that disconnects Ras from its signaling network while inducing limited structural disturbance in its target.

PMID- 30279172 TI - Age-Related Changes in HAPLN1 Increase Lymphatic Permeability and Affect Routes of Melanoma Metastasis. AB - Older melanoma patients have lower rates of sentinel lymph node (LN) metastases yet paradoxically have inferior survival. Patient age correlated with an inability to retain Technetium radiotracer during sentinel LN biopsy in over 1000 patients, and high technecium counts correlated to better survival. We hypothesized that loss of integrity in the lymphatic vasculature due to ECM degradation might play a role. We have implicated HAPLN1 in age-dependent ECM degradation in the dermis. Here we queried whether HAPLN1 could be altered in the lymphatic ECM. Lymphatic HAPLN1 expression was prognostic of long-term patient survival. Adding rHAPLN1 to aged fibroblast ECMs in vitro reduced endothelial permeability via modulation of VE-Cadherin junctions, whereas endothelial permeability was increased following HAPLN1-knockdown in young fibroblasts. In vivo, reconstitution of HAPLN1 in aged mice increased the number of LN metastases, but reduced visceral metastases. These data suggest that age-related changes in ECM can contribute to impaired lymphatics. PMID- 30279173 TI - Remodeling of the collagen matrix in aging skin promotes melanoma metastasis and affects immune cell motility. AB - Physical changes in skin are among the most visible signs of aging. We found that young dermal fibroblasts secrete high levels of extracellular matrix (ECM) constituents, including proteoglycans, glycoproteins and cartilage-linking proteins. The most abundantly secreted was HAPLN1, a hyaluronic and proteoglycan link protein. HAPLN1 was lost in aged fibroblasts, resulting in a more aligned ECM that promoted metastasis of melanoma cells. Reconstituting HAPLN1 inhibited metastasis in an aged microenvironment, in 3D skin reconstruction models, and in vivo. Intriguingly, aged fibroblast-derived matrices had the opposite effects on the migration of T-cells, inhibiting their motility. HAPLN1 treatment of aged fibroblasts restored motility of mononuclear immune cells, while impeding that of polymorphonuclear immune cells, which in turn affected Treg recruitment. These data suggest while age-related physical changes in the ECM can promote tumor cell motility, they may adversely impact the motility of some immune cells, resulting in an overall change in the immune microenvironment. Understanding the physical changes in aging skin may provide avenues for more effective therapy for older melanoma patients. PMID- 30279174 TI - Performance analysis of SiRe next-generation sequencing panel in diagnostic setting: focus on NSCLC routine samples. AB - AIMS: Following the development for liquid biopsies of the SiRe next-generation sequencing (NGS) panel that covers 568 clinical relevant mutations in EGFR, KRAS, NRAS, BRAF, cKIT and PDGFRa genes, in this current study, we apply this small NGS panel on tissue samples of lung cancer. METHODS: A total of 322 specimens were prospectively tested. Technical parameters were analysed on both cytological and histological samples. In a subset of 75 samples, the EGFR SiRe results were compared with those generated by the European Community (CE)-IVD EGFR assay on Idylla platform. Clinical outcomes of 11 patients treated, on the basis of SiRe results, were also evaluated. RESULTS: Only 28 (8.7%) specimens failed to produce a library; out of the 294 remaining samples, a total of 168 somatic mutations were found. In nearly all instances (74/75-99%), the EGFR SiRe results were confirmed by Idylla. In general, SiRe analytical parameters were excellent. However, histological and cytological specimens differed in relation to average reads for sample, mean number of mapped reads, median read length and average reads for amplicon. Treatment outcome evaluation in 11 patients showed a partial response in 82 % (9/11) patients with a median progression-free survival of 340 days. CONCLUSIONS: The small gene panel SiRe is a clinically relevant tool useful to widespread the adoption of NGS in predictive molecular pathology laboratories.

AB - CD4+ T follicular helper (TFH) cells support germinal center (GC) reactions promoting humoral immunity. Dendritic cell (DC) diversification into genetically distinct subsets allows for specialization in promoting responses against several types of pathogens. Whether any classical DC (cDC) subset is required for humoral immunity is unknown, however. We tested several genetic models that selectively ablate distinct DC subsets in mice for their impact on splenic GC reactions. We identified a requirement for Notch2-dependent cDC2s, but not Batf3-dependent cDC1s or Klf4-dependent cDC2s, in promoting TFH and GC B cell formation in response to sheep red blood cells and inactivated Listeria monocytogenes This effect was mediated independent of Il2ra and several Notch2-dependent genes expressed in cDC2s, including Stat4 and Havcr2 Notch2 signaling during cDC2 development also substantially reduced the efficiency of cDC2s for presentation of MHC class II-restricted antigens, limiting the strength of CD4 T cell activation. Together, these results demonstrate a nonredundant role for the Notch2-dependent cDC2 subset in supporting humoral immune responses. PMID- 30279177 TI - Amphiregulin-producing gammadelta T cells are vital for safeguarding oral barrier immune homeostasis. AB - gammadelta T cells are enriched at barrier sites such as the gut, skin, and lung, where their roles in maintaining barrier integrity are well established. However, how these cells contribute to homeostasis at the gingiva, a key oral barrier and site of the common chronic inflammatory disease periodontitis, has not been explored. Here we demonstrate that the gingiva is policed by gammadelta T cells with a T cell receptor (TCR) repertoire that diversifies during development. Gingival gammadelta T cells accumulated rapidly after birth in response to barrier damage, and strikingly, their absence resulted in enhanced pathology in murine models of the oral inflammatory disease periodontitis. Alterations in bacterial communities could not account for the increased disease severity seen in gammadelta T cell-deficient mice. Instead, gingival gammadelta T cells produced the wound healing associated cytokine amphiregulin, administration of which rescued the elevated oral pathology of tcrdelta -/- mice. Collectively, our results identify gammadelta T cells as critical constituents of the immuno surveillance network that safeguard gingival tissue homeostasis. PMID- 30279179 TI - Education can reduce health differences related to genetic risk of obesity. AB - This work investigates whether genetic makeup moderates the effects of education on health. Low statistical power and endogenous measures of environment have been obstacles to the credible estimation of such gene-by-environment interactions. We overcome these obstacles by combining a natural experiment that generated variation in secondary education with polygenic scores for a quarter-million individuals. The additional schooling affected body size, lung function, and blood pressure in middle age. The improvements in body size and lung function were larger for individuals with high genetic predisposition to obesity. As a result, education reduced the gap in unhealthy body size between those in the top and bottom terciles of genetic risk of obesity from 20 to 6 percentage points. PMID- 30279178 TI - Enhanced dynamic nuclear polarization via swept microwave frequency combs. AB - Dynamic nuclear polarization (DNP) has enabled enormous gains in magnetic resonance signals and led to vastly accelerated NMR/MRI imaging and spectroscopy. Unlike conventional cw-techniques, DNP methods that exploit the full electron spectrum are appealing since they allow direct participation of all electrons in the hyperpolarization process. Such methods typically entail sweeps of microwave radiation over the broad electron linewidth to excite DNP but are often inefficient because the sweeps, constrained by adiabaticity requirements, are slow. In this paper, we develop a technique to overcome the DNP bottlenecks set by the slow sweeps, using a swept microwave frequency comb that increases the effective number of polarization transfer events while respecting adiabaticity constraints. This allows a multiplicative gain in DNP enhancement, scaling with the number of comb frequencies and limited only by the hyperfine-mediated electron linewidth. We demonstrate the technique for the optical hyperpolarization of 13C nuclei in powdered microdiamonds at low fields, increasing the DNP enhancement from 30 to 100 measured with respect to the thermal signal at 7T. For low concentrations of broad linewidth electron radicals [e.g., TEMPO ((2,2,6,6-tetramethylpiperidin-1-yl)oxyl)], these multiplicative gains could exceed an order of magnitude. PMID- 30279180 TI - Structural characterization of the D290V mutation site in hnRNPA2 low-complexity domain polymers. AB - Human genetic studies have given evidence of familial, disease-causing mutations in the analogous amino acid residue shared by three related RNA binding proteins causative of three neurological diseases. Alteration of aspartic acid residue 290 of hnRNPA2 to valine is believed to predispose patients to multisystem proteinopathy. Mutation of aspartic acid 262 of hnRNPA1 to either valine or asparagine has been linked to either amyotrophic lateral sclerosis or multisystem proteinopathy. Mutation of aspartic acid 378 of hnRNPDL to either asparagine or histidine has been associated with limb girdle muscular dystrophy. All three of these aspartic acid residues map to evolutionarily conserved regions of low complexity (LC) sequence that may function in states of either intrinsic disorder or labile self-association. Here, we present a combination of solid-state NMR spectroscopy with segmental isotope labeling and electron microscopy on the LC domain of the hnRNPA2 protein. We show that, for both the wild-type protein and the aspartic acid 290-to-valine mutant, labile polymers are formed in which the LC domain associates into an in-register cross-beta conformation. Aspartic acid 290 is shown to be charged at physiological pH and immobilized within the polymer core. Polymers of the aspartic acid 290-to-valine mutant are thermodynamically more stable than wild-type polymers. These observations give evidence that removal of destabilizing electrostatic interactions may be responsible for the increased propensity of the mutated LC domains to self-associate in disease causing conformations. PMID- 30279183 TI - Using a natural experiment to estimate the electoral consequences of terrorist attacks. AB - This study investigates the consequences of terrorist attacks for political behavior by leveraging a natural experiment in Spain. We study eight attacks against civilians, members of the military, and police officers perpetrated between 1989 and 1997 by Euskadi Ta Askatasuna (ETA), a Basque terrorist organization that was active between 1958 and 2011. We use nationally and regionally representative surveys that were being fielded when the attacks occurred to estimate the causal effect of terrorist violence on individuals' intent to participate in democratic elections as well as on professed support for the incumbent party. We find that both lethal and nonlethal terrorist attacks significantly increase individuals' intent to participate in a future democratic election. The magnitude of this impact is larger when attacks are directed against civilians than when directed against members of the military or the police. We find no evidence that the attacks change support for the incumbent party. These results suggest that terrorist attacks enhance political engagement of citizens. PMID- 30279181 TI - Long noncoding RNA SYISL regulates myogenesis by interacting with polycomb repressive complex 2. AB - Although many long noncoding RNAs (lncRNAs) have been identified in muscle, their physiological function and regulatory mechanisms remain largely unexplored. In this study, we systematically characterized the expression profiles of lncRNAs during C2C12 myoblast differentiation and identified an intronic lncRNA, SYISL (SYNPO2 intron sense-overlapping lncRNA), that is highly expressed in muscle. Functionally, SYISL promotes myoblast proliferation and fusion but inhibits myogenic differentiation. SYISL knockout in mice results in significantly increased muscle fiber density and muscle mass. Mechanistically, SYISL recruits the enhancer of zeste homolog 2 (EZH2) protein, the core component of polycomb repressive complex 2 (PRC2), to the promoters of the cell-cycle inhibitor gene p21 and muscle-specific genes such as myogenin (MyoG), muscle creatine kinase (MCK), and myosin heavy chain 4 (Myh4), leading to H3K27 trimethylation and epigenetic silencing of target genes. Taken together, our results reveal that SYISL is a repressor of muscle development and plays a vital role in PRC2 mediated myogenesis. PMID- 30279182 TI - Cryo-EM structures of ASC and NLRC4 CARD filaments reveal a unified mechanism of nucleation and activation of caspase-1. AB - Canonical inflammasomes are cytosolic supramolecular complexes that activate caspase-1 upon sensing extrinsic microbial invasions and intrinsic sterile stress signals. During inflammasome assembly, adaptor proteins ASC and NLRC4 recruit caspase-1 through homotypic caspase recruitment domain (CARD) interactions, leading to caspase-1 dimerization and activation. Activated caspase-1 processes proinflammatory cytokines and Gasdermin D to induce cytokine maturation and pyroptotic cell death. Here, we present cryo-electron microscopy (cryo-EM) structures of NLRC4 CARD and ASC CARD filaments mediated by conserved three types of asymmetric interactions (types I, II, and III). We find that the CARDs of these two adaptor proteins share a similar assembly pattern, which matches that of the caspase-1 CARD filament whose structure we defined previously. These data indicate a unified mechanism for downstream caspase-1 recruitment through CARD CARD interactions by both adaptors. Using structure modeling, we further show that full-length NLRC4 assembles via two separate symmetries at its CARD and its nucleotide-binding domain (NBD), respectively. PMID- 30279184 TI - Model of bacterial toxin-dependent pathogenesis explains infective dose. AB - The initial amount of pathogens required to start an infection within a susceptible host is called the infective dose and is known to vary to a large extent between different pathogen species. We investigate the hypothesis that the differences in infective doses are explained by the mode of action in the underlying mechanism of pathogenesis: Pathogens with locally acting mechanisms tend to have smaller infective doses than pathogens with distantly acting mechanisms. While empirical evidence tends to support the hypothesis, a formal theoretical explanation has been lacking. We give simple analytical models to gain insight into this phenomenon and also investigate a stochastic, spatially explicit, mechanistic within-host model for toxin-dependent bacterial infections. The model shows that pathogens secreting locally acting toxins have smaller infective doses than pathogens secreting diffusive toxins, as hypothesized. While local pathogenetic mechanisms require smaller infective doses, pathogens with distantly acting toxins tend to spread faster and may cause more damage to the host. The proposed model can serve as a basis for the spatially explicit analysis of various virulence factors also in the context of other problems in infection dynamics. PMID- 30279185 TI - Development and validation of an automated algorithm for identifying patients at high risk for drug-induced hypoglycemia. AB - PURPOSE: Hypoglycemia is one of the most concerning adverse drug events in hospitalized patients. Using information from institutional electronic health records, we aimed to develop dynamic predictive models to identify patients at high risk for hypoglycemia during antihyperglycemic therapy. METHODS: The study population consisted of 21,840 patients who received antihyperglycemic medication on any of the first 5 hospital days (the "risk model days") at 2 large hospitals. Data on candidate predictors were extracted from discrete electronic health record fields to construct models for predicting hypoglycemia within 24 hours after each risk model day. Final models were internally validated by replication in 100 bootstrap samples and reapplying model parameters to the original risk population. RESULTS: The development and validation sample included 60,762 risk model days followed by 1,256 days with hypoglycemic events (2.07 events per 100 risk model days). The days 3, 4, and 5 models presented similar associations between predictors and the risk of hypoglycemia and were therefore collapsed into a single model. The strongest hypoglycemia risk factors across all 3 risk periods (day 1, day 2, and days 3-5) were blood glucose (BG) fluctuations, BG trend, history of hypoglycemia, lower body weight, lower creatinine clearance, use of long-acting or high-dose insulin, and sulfonylurea use. C statistics for the 3 models ranged from 0.844 to 0.887. Depending on the model used, risk scores in the upper 90th percentile predicted 48.5-63.1% of actual hypoglycemic events. It was estimated that by targeting only patients in the upper 90th percentile, providers would need to intervene during fewer than 9 admissions to prevent 1 hypoglycemic event. CONCLUSION: The developed prediction models were found to have excellent discriminative validity and good calibration, allowing clinicians to focus interventions on a select high-risk population in which the majority of hypoglycemic events occur.

PMID- 30279186 TI - Early childcare type predicts children's emotional and behavioural trajectories into middle childhood. Data from the EDEN mother-child cohort study. AB - BACKGROUND: The scientific literature on the impact of early childcare on children's behavioural and emotional difficulties shows contrasting results. We studied this association in France, where childcare is of high quality and children enter preschool at the age of 3. METHODS: 1428 children from the EDEN (Etude des Determinants du developpement et de la sante de l'ENfant) mother-child cohort set up in France (Nancy and Poitiers) were followed up since pregnancy to the age of 8 years. Group-based trajectory modelling was used to model their trajectories of behavioural and emotional symptoms (emotional symptoms, peer relationship problems, hyperactivity/inattention, conduct problems, prosocial behaviours) ascertained by three measures (3, 5.5 and 8 years) of the Strengths and Difficulties Questionnaire. Using propensity scores and inverse probability weights (IPWs) to account for selection and confounding factors, we compared children in a childminder's care or in centre-based childcare (from birth to age 3) with those in informal childcare. RESULTS: Compared with children in informal childcare, those who attended centre-based childcare had a lower likelihood of having high levels of emotional symptoms (ORIPW-adjusted=0.35, 95% CI 0.17 to 0.71), peer relationship problems (ORIPW-adjusted=0.31, 95% CI 0.15 to 0.67) and low prosocial behaviours (ORIPW-adjusted=0.50, 95% CI 0.28 to 0.90). Those who were looked after by a childminder had a higher likelihood of following a high trajectory of conduct problems (ORIPW-adjusted=1.72, 95% CI 1.05 to 2.81). Attendance of centre-based childcare for more than 1 year was especially protective of high levels of emotional, peer-related difficulties and low prosocial behaviours. Girls and children from a favourable socioeconomic background reaped more benefits of childcare than boys and those from a less favourable background. CONCLUSION: High-quality centre-based childcare may be linked to lower levels of emotional symptoms. PMID- 30279188 TI - Predictive Biomarkers for Checkpoint Immunotherapy: Current Status and Challenges for Clinical Application. AB - Immune-checkpoint blockade (ICB), in particular PD-1 inhibition, has rapidly changed the treatment landscape and altered therapeutic paradigms across many tumor types, with unprecedented rates of durable clinical responses in a number of cancers. Despite this success, only a subset of patients responds to ICB and, as a result, predictive biomarkers would be useful to guide the selection of patients for these therapies. This article highlights currently used biomarkers, as well as several promising novel candidates, and also discusses the challenges involved in establishing their analytic validity and clinical utility. Progress is being evaluated in melanoma and non-small cell lung cancer, for which PD-1 +/- CTLA-4 inhibitors have become standard therapy, to other malignancies for which PD-L1 inhibitors remain investigational. Although single biomarkers have substantial limitations, a combination of biomarkers that reflect the interaction of host and tumor will likely be needed to provide a reproducible surrogate for the benefit of checkpoint modulation.

AB - In the C. elegans embryo, the germline lineage is established through successive asymmetric cell divisions that each generate a somatic and a germline daughter cell. PIE-1 is an essential maternal factor that is enriched in embryonic germline cells and is required for germline specification. We estimated the absolute concentration of PIE-1::GFP in germline cells and find that PIE-1::GFP concentration increases by roughly 4.5 fold, from 92 nM to 424 nM, between the 1 and 4-cell stages. Previous studies have shown that the preferential inheritance of PIE-1 by germline daughter cells and the degradation of PIE-1 in somatic cells are important for PIE-1 enrichment in germline cells. In this study, we provide evidence that the preferential translation of maternal PIE-1::GFP transcripts in the germline also contributes to PIE-1::GFP enrichment. Through an RNAi screen, we identified Y14 and MAG-1 (Drosophila tsunagi and mago nashi) as regulators of embryonic PIE-1::GFP levels. We show that Y14 and MAG-1 do not regulate PIE-1 degradation, segregation or synthesis in the early embryo, but do regulate the concentration of maternally-deposited PIE-1::GFP. Taken together, or findings point to an important role for translational control in the regulation of PIE-1 levels in the germline lineage.

PMID- 30279196 TI - Aberrant cerebellar Purkinje cell activity as the cause of motor attacks in a mouse model of episodic ataxia type 2. AB - Many cerebellar-induced neurological disorders, such as ataxias and cerebellar induced dystonias, are associated with abnormal Purkinje cell activity. In tottering mice, a well-established mouse model of episodic ataxia type 2 (EA2), cerebellar Purkinje cells are required for the initiation of motor attacks. How Purkinje cells contribute to the initiation of attacks is not known, and to date there are no reports on the activity of Purkinje cells during motor attacks in the tottering mice. Here, we show that tottering Purkinje cells exhibit high frequency burst firing during attacks, reminiscent of other mouse models of cerebellar-induced motor dysfunction. We recorded the activity of Purkinje cells in awake head-restrained tottering mice at baseline, or during caffeine-induced attacks. During motor attacks, firing of Purkinje cells transformed to high frequency burst firing. Interestingly, the extent to which the activity of Purkinje cells was erratic was correlated with the severity of the motor dysfunction. In support of a causal role for erratic activity in generating motor dysfunction, we found that direct infusion of the small conductance calcium activated potassium (SK) channel activator NS309 into the cerebellum of tottering mice in the midst of an attack normalized the firing of Purkinje cells and aborted attacks. Conversely, we found that inducing high-frequency burst firing of Purkinje cells in wild-type animals is sufficient to produce severe motor signs. We report that erratic activity of wild-type Purkinje cells results in ataxia and dystonic postures. Moreover, this aberrant activity is the cause of motor attacks in the tottering mice. PMID- 30279198 TI - Local and systemic metabolic responses during light-induced rapid systemic signaling. AB - Plants evolved multiple signaling pathways that transduce light-related signals between leaves. These are thought to improve light stress acclimation in a process termed systemic acquired acclimation (SAA). Although responses to light stress have been extensively studied in local leaves, and to a lesser degree in systemic leaves, little is known about the responses that occur in the different tissues that connect the local to the systemic leaves. These could be important in defining the specificity of the systemic response, as well as in supporting the generation of different systemic signals. Here we report that local application of light stress to one rosette leaf of bolting Arabidopsis thaliana plants resulted in a metabolic response that encompassed local, systemic and transport tissues (stem tissues that connect the local to the systemic tissues), demonstrating a high degree of physical and metabolic continuity between different tissues throughout the plant. Our results further indicate that the response of many of the systemically altered metabolites is associated with the function of the reactive oxygen species wave, and that the level of eight different metabolites is altered in a similar manner in all tissues tested (local, systemic, and transport). These compounds could define a core metabolic signature for light stress that propagates from the local to the systemic leaves. Our findings suggest that metabolic changes occurring in cells that connect the local and systemic tissues play an important role in SAA and could convey specificity to the rapid systemic response of plants to light stress. PMID- 30279199 TI - Adherence to AAP Healthy Newborn Discharge Criteria in a Tertiary Care Children's Hospital. AB - OBJECTIVES: In 2015, the American Academy of Pediatrics (AAP) published an updated consensus statement containing 17 discharge recommendations for healthy term newborn infants. In this study, we identify whether the AAP criteria were met before discharge at a tertiary care academic children's hospital. METHODS: A stratified random sample of charts from newborns who were discharged between June 1, 2015, and May 31, 2016, was reviewed. Of the 531 charts reviewed, 433 were included in the study. A review of each chart was performed, and data were collected. RESULTS: Descriptive statistics for our study population (N = 433) revealed that all 17 criteria were followed <5% of the time. The following criteria were met 100% of the time: clinical course and physical examination, postcircumcision bleeding, availability of family members or health care providers to address follow-up concerns, anticipatory guidance, first appointment with the physician scheduled or parents knowing how to do so, pulse oximetry screening, and hearing screening. These criteria were met at least 95% to 99% of the time: appropriate vital signs, regular void and stool frequency, appropriate jaundice and sepsis management, and metabolic screening. The following criteria were met 50% to 95% of the time: maternal serologies, hepatitis B vaccination, and social risk factor assessment. Four of the criteria were met <50% of the time: feeding assessment, maternal vaccination, follow-up timing for newborns discharged at <48 hours of life, and car safety-seat assessment. CONCLUSIONS: Our data reveal that the AAP healthy term newborn discharge recommendations are not consistently followed in our institution. PMID- 30279197 TI - Six months versus 12 months dual antiplatelet therapy after drug-eluting stent implantation in ST-elevation myocardial infarction (DAPT-STEMI): randomised, multicentre, non-inferiority trial. AB - OBJECTIVE: To show that limiting dual antiplatelet therapy (DAPT) to six months in patients with event-free ST-elevation myocardial infarction (STEMI) results in a non-inferior clinical outcome versus DAPT for 12 months. DESIGN: Prospective, randomised, multicentre, non-inferiority trial. SETTING: Patients with STEMI treated with primary percutaneous coronary intervention (PCI) and second generation zotarolimus-eluting stent. PARTICIPANTS: Patients with STEMI aged 18 to 85 that underwent a primary PCI with the implantation of second generation drug-eluting stents were enrolled in the trial. Patients that were event-free at six months after primary PCI were randomised at this time point. INTERVENTIONS: Patients that were taking DAPT and were event-free at six months were randomised 1:1 to single antiplatelet therapy (SAPT) (ie, aspirin only) or to DAPT for an additional six months. All patients that were randomised were then followed for another 18 months (ie, 24 months after the primary PCI). MAIN OUTCOME MEASURES: The primary endpoint was a composite of all cause mortality, any myocardial infarction, any revascularisation, stroke, and thrombolysis in myocardial infarction major bleeding at 18 months after randomisation. RESULTS: A total of 1100 patients were enrolled in the trial between 19 December 2011 and 30 June 2015. 870 were randomised: 432 to SAPT versus 438 to DAPT. The primary endpoint occurred in 4.8% of patients receiving SAPT versus 6.6% of patients receiving DAPT (hazard ratio 0.73, 95% confidence interval 0.41 to 1.27, P=0.26). Non inferiority was met (P=0.004 for non-inferiority), as the upper 95% confidence interval of 1.27 was smaller than the prespecified non-inferiority margin of 1.66. CONCLUSIONS: DAPT to six months was non-inferior to DAPT for 12 months in patients with event-free STEMI at six months after primary PCI with second generation drug-eluting stents.

PMID- 30279202 TI - Long non-coding RNA linc-ITGB1 promotes cell proliferation, migration, and invasion in human hepatoma carcinoma by up-regulating ROCK1. AB - Background: Linc-ITGB1 is a newly identified long non-coding RNA (lncRNA) involved in the regulation of cell migration and invasion of gallbladder cancer cell lines, while its involvement in human hepatoma carcinoma (HCC) is unknown. Methods: In the present study, HCC patient tumor tissues, adjacent healthy tissues and whole blood were collected from both HCC patients and healthy controls. Expression of LINC-ITGB1 was examined by qRT-PCR. Diagnostic value of serum LINC-ITGB1 for HCC was evaluated by receiver operating characteristic (ROC) curve analysis. Correlation between the serum LINC-ITGB1 and basic clinical information of patients was analyzed by chi-square test. LINC-ITGB1 overexpression HCC cell lines were established and the effects on cell proliferation, migration, and invasion were explored by CCK-8 assay and Transwell assay. Effects of LINC-ITGB1 overexpression on Rho-associated, coiled-coil containing protein kinase 1 (ROCK1) expression were investigated by Western blot. Results: We found that LINC-ITGB1 was up-regulated in tumor tissues than in adjacent healthy tissues. Serum levels of LINC-ITGB1 were higher in HCC patients than in healthy controls. Serum levels of LINC-ITGB1 were significantly correlated with tumor size and distant tumor metastasis. LINC-ITGB1 overexpression promoted the proliferation, migration, and invasion of HCC cells and the expression of ROCK1. ROCK1 inhibitor reduced the effects of LINC-ITGB1 overexpression on cell proliferation, migration, and invasion. Conclusion: We conclude that lncRNA LINC-ITGB1 can promote the proliferation, migration, and invasion of HCC cells by up-regulating ROCK1. PMID- 30279203 TI - The role of perineural invasion in penile cancer: a meta-analysis and systematic review. AB - The significance of perineural invasion (PNI) present in penile cancer (PC) is controversial. In order to clarify the predictive role of PNI in the inguinal lymph node (ILN) metastases (ILNM) and oncologic outcome of patients, we performed this meta-analysis and systematic review. The search of PubMed, Embase, and Web of Science was conducted for appropriate studies, up to 20 January 2018. The pooled odds ratio (OR) and hazard ratio (HR) with their 95% confidence interval (CI) were applied to evaluate the difference in ILNM and oncologic outcome between patients present with PNI and those who were absent. A total of 298 in 1001 patients present with PNI were identified in current meta-analysis and systematic review. Significant difference was observed in ILNM between PNI present and absent from patients with PC (OR = 2.98, 95% CI = 2.00-4.45). Patients present with PNI had a worse cancer-specific survival (CSS) (HR = 3.58, 95% CI = 1.70-7.55) and a higher cancer-specific mortality (CSM) (HR = 2.20, 95% CI = 1.06-3.82) than those cases without PNI. This meta-analysis and systematic review demonstrated the predictive role of PNI in ILNM, CSS, and CSM for PC patients. PMID- 30279204 TI - Dihydro-sphingosine 1-phosphate interacts with carrier proteins in a manner distinct from that of sphingosine 1-phosphate. AB - Dihydro-sphingosine 1-phosphate (DH-S1P) is an analog of sphingosine 1-phosphate (S1P), which is a potent lysophospholipid mediator. DH-S1P has been proposed to exert physiological properties similar to S1P. Although S1P is known to be carried on HDL via apolipoprotein M (apoM), the association between DH-S1P and HDL/apoM has not been fully elucidated. Therefore, in the present study, we aimed to elucidate this association and to compare it with that of S1P and HDL/apoM. First, we investigated the distributions of S1P and DH-S1P among lipoproteins and lipoprotein-depleted fractions in human serum and plasma samples and observed that both S1P and DH-S1P were detected on HDL; furthermore, elevated amounts of DH-S1P in serum samples were distributed to the lipoprotein-depleted fraction to a greater degree than to the HDL fraction. Concordantly, a preference for HDL over albumin was only observed for S1P, and not for DH-S1P, when the molecules were secreted from platelets. Regarding the association with HDL, although both S1P and DH-S1P prefer to bind to HDL, HDL preferentially accepts S1P over DH-S1P. For the association with apoM, S1P was not detected on HDL obtained from apoM knockout mice, while DH-S1P was detected. Moreover, apoM retarded the degradation of S1P, but not of DH-S1P. These results suggest that S1P binds to HDL via apoM, while DH-S1P binds to HDL in a non-specific manner. Thus, DH-S1P is not a mere analog of S1P and might possess unique clinical significance. PMID- 30279205 TI - Association between the polymorphisms of CALM1 gene and osteoarthritis risk: a meta-analysis based on observational studies. AB - The existing studies on the association between polymorphisms of Calmodulin 1 (CALM1) gene and the risk of osteoarthritis (OA, a complex multifactorial disease and a major degenerative form of arthritis) in different populations have yielded conflicting findings. Therefore, we conducted a meta-analysis by systematically searching PubMed, Embase, Medline, Cochrane Library and Google Scholar, and assessing this association by calculating pooled odds ratios with 95% confidence intervals. Subgroup analyses stratified by ethnicity, OA type, and genotype were also conducted. Six studies (2752 cases and 3259 controls) involving six single nucleotide polymorphisms were included. Our data suggested that the T allele and genotype TT of the rs12885713 polymorphism, and the C allele of the rs2300496 polymorphism in the CALM1 gene all increased the risk of OA. The pooled results revealed no significant association between the CALM1 rs3213718 polymorphism and the risk of OA. Stratification analyses by ethnicity and OA type showed that the rs12885713 polymorphism increased the risk of OA among Asians and in knee OA, respectively. In conclusion, the rs12885713 and rs2300496 polymorphisms of the CALM1 gene may both increase the risk of OA. Owing to the limitations of the present study, this finding should be further confirmed in future well-designed studies. PMID- 30279206 TI - ANRIL promotes chemoresistance via disturbing expression of ABCC1 by regulating the expression of Let-7a in colorectal cancer. AB - Increasing evidence indicates that long non-coding RNAs (lncRNAs) antisense non coding RNA in the INK4 locus (ANRIL) has been involved in various diseases and promotes tumorigenesis and cancer progression as an oncogenic gene. However, the effect of ANRIL on chemoresistance remains still unknown in colorectal cancer (CRC). Here, we investigated ANRIL expression in 63 cases of colorectal cancer specimens and matched normal tissues. Results revealed that ANRIL was up regulated in tumor tissues samples from patients with CRC and CRC cell lines. Increased ANRIL expression in CRC was associated with poor clinical prognosis. Kaplan-Meier analysis showed that ANRIL was associated with overall survival of patients with colorectal cancer, and patients with high ANRIL expression tended to have unfavorable outcome. In vitro experiments revealed that ANRIL knockdown significantly inhibited CRC cell proliferation, improved the sensitivity of chemotherapy and promoted apoptosis. Further functional assays indicated that ANRIL overexpression significantly promoted cell chemoresistance by regulating ATP-binding cassette subfamily C member 1 through binding Let-7a. Taken together, our study demonstrates that ANRIL could act as a functional oncogene in CRC, as well as a potential therapeutic target to inhibit CRC chemoresistance. PMID- 30279207 TI - Specific expression of lncRNA RP13-650J16.1 and TCONS_00023979 in prostate cancer. AB - The aim of the present study was to explore the expression profile and the potential regulatory mechanism of two long non-coding RNAs (lncRNAs) (RP13 650J16.1 and TCONS_00023979) in prostate cancer (PCa). Expression profile of lncRNAs in PCa and paracancerous tissues were investgated by the high-throughput gene chip technology. Specific siRNA of RP13-650J16.1 or TCONS_00023979 was transfected into DU145 cells. Then, the relative expression of RP13-650J16.1, receptor-associated coactivator 3 (RAC3), promyelocytic leukemia (PML), and TCONS_00023979 was detected by quantitative real-time PCR and Western blotting. MTT assay was used to detect the proliferation of DU145 cells. The migration ability of DU145 cells was measured by Transwell chambers. Single cell proliferation and clonogenic ability were detected by plate clone formation assay. RP13-650J16.1 and RAC3 expression was up-regulated, and TCONS_00023979 and PML expression was down-regulated in PCa tissues. Silencing RP13-650J16.1 could decrease RAC3 expression, and knockout of TCONS_00023979 also reduced PML expression. Moreover, the ability of proliferation, migration, and colony formation of DU145 cells was decreased after transfected with si-RP13-650J16.1, while these abilities were increased after transfected with si-TCONS_00023979. Collectively, our findings demonstrated that RP13-650J16.1 might be an oncogene and TCONS_00023979 might be an antioncogene in PCa. PMID- 30279208 TI - von Willebrand factor rescued by miR-24 inhibition facilitates the proliferation and migration of osteosarcoma cells in vitro. AB - von Willebrand factor (vWF) is a major procoagulant molecule that was shown to differentiate between metastatic and primary osteosarcoma (OS) tissues and associated with increased metastasis. However, its functional role in OS progression has been unclear yet. The expression profile of vWF and miR-24 in human OS tissues was characterized using immunofluorescence labeling and quantitative real-time PCR analysis. The interaction between miR-24 and vWF was identified by dual luciferase reporter assay. The effects of vWF and miR-24 on OS cells were assessed by cell proliferation, colony formation, and migration. The clinical significance of miR-24 in OS patients was analyzed using Kaplan-Meier analyses and Pearson's Chi-squared test. Here, we reported that the expression of vWF was significantly increased, but miR-24 was significantly decreased in OS tissues (n=84). vWF was further validated as the target of miR-24 in MG-63 and U2OS cells. miR-24 obviously suppressed the proliferation and migration of MG-63 and U2OS cells. However, the migration-inhibiting activity of miR-24 was predominantly attenuated by vWF overexpression. Clinically, low miR-24 expression in human OS tissues was significantly associated with tumor metastasis and predicted a poor survival in OS patients. This work demonstrated that vWF, as a downstream effector of miR-24, played an important role in controlling OS cell progression. Target miR-24 or vWF, therefore, promises to be an effective biological target for OS treatment. PMID- 30279210 TI - A novel antimicrobial peptide, Ranatuerin-2PLx, showing therapeutic potential in inhibiting proliferation of cancer cells. AB - Antimicrobial peptides are a promising resource for developing novel antibiotic and even anticancer drugs. Here, a 28-mer polypeptide, Ranatuerin-2PLx (R2PLx), was identified from lyophilised skin secretions. The chemically synthetic replicates exhibited moderate and broadspectrum antimicrobial effect against various microorganisms including methicillin-resistant Staphylococcus aureus (MRSA, minimal inhibitory concentration = 256 uM). In addition, R2PLx was found to inhibit the proliferation of several tumour cells, especially showing more potent effect on prostate cancer cell, PC-3. The early cell apoptosis was observed in 6 h by Annexin V-FITC/propidium iodide staining, as well as the activation of Caspase-3 at 5 uM peptide concentration. R2PLx may therefore be promising for developing new therapeutic approach for cancer treatment. Moreover, the artificial deficiency of conserved rana-box loop or net positive charge in C terminal domain notably reduced the biological activities of the truncated and substituted isoforms, respectively, suggesting for maintaining their biological potency of ranatuerin family requires both cysteine-bridged segment and cationincity within the loop domain in C-terminus. PMID- 30279211 TI - Lifetime risk of common neurological diseases in the elderly population. AB - OBJECTIVE: To quantify the burden of common neurological disease in older adults in terms of lifetime risks, including their co-occurrence and preventive potential, within a competing risk framework. METHODS: Within the prospective population-based Rotterdam Study, we studied lifetime risk of dementia, stroke and parkinsonism between 1990 and 2016. Among 12 102 individuals (57.7% women) aged >=45 years free from these diseases at baseline, we studied co-occurrence, and quantified the combined, and disease-specific remaining lifetime risk of these diseases at various ages for men and women separately. We also projected effects on lifetime risk of hypothetical preventive strategies that delay disease onset by 1, 2 and 3 years, respectively. RESULTS: During follow-up of up to 26 years (156 088 person-years of follow-up), 1489 individuals were diagnosed with dementia, 1285 with stroke and 263 with parkinsonism. Of these individuals, 438 (14.6%) were diagnosed with multiple diseases. Women were almost twice as likely as men to be diagnosed with both stroke and dementia during their lifetime. The lifetime risk for any of these diseases at age 45 was 48.2% (95% CI 47.1% to 51.5%) in women and 36.2% (35.1% to 39.3%) in men. This difference was driven by a higher risk of dementia as the first manifesting disease in women than in men (25.9% vs 13.7%; p<0.001), while this was similar for stroke (19.0%vs18.9% in men) and parkinsonism (3.3% vs 3.6% in men). Preventive strategies that delay disease onset with 1 to 3 years could theoretically reduce lifetime risk for developing any of these diseases by 20%-50%. CONCLUSION: One in two women and one in three men will develop dementia, stroke or parkinsonism during their life. These findings strengthen the call for prioritising the focus on preventive interventions at population level which could substantially reduce the burden of common neurological diseases in the ageing population.

PMID- 30279209 TI - The potential roles of circRNAs in osteoarthritis: a coming journey to find a treasure. AB - Osteoarthritis (OA), a common joint disease in elderly, causes serious social and economic burdens worldwide. Previous studies indicated that some differentially expressed circular RNAs (circRNAs) participated in the initiation and progression of OA. These findings suggested that circRNAs may act as promising diagnostic biomarkers and therapeutic targets for OA. In this review, we summarize the biogenesis and biological functions of circRNAs and explore the underlying roles of circRNAs in OA, which may enlighten further studies and contribute to the early diagnosis and intervention of OA. PMID- 30279213 TI - Proposal of new clinical diagnostic criteria for POEMS syndrome. AB - OBJECTIVE: To propose the optimal diagnostic criteria for polyneuropathy, organomegaly, endocrinopathy, M-protein and skin changes (POEMS) syndrome using appropriate statistical methods and disease controls. METHODS: This retrospective cohort study included 104 consecutive patients with suspected POEMS syndrome, among whom a gold standard group of 60 patients with definitive POEMS syndrome diagnosis were followed for at least 12 months to strictly exclude other disorders mimicking POEMS syndrome and to confirm response to POEMS syndrome specific treatment. Thirty patients with chronic inflammatory demyelinating polyradiculoneuropathy (demyelinating polyradiculoneuropathy controls) and 30 with multiple myeloma or immunoglobulin light chain amyloidosis (monoclonal plasma cell proliferation controls) were also included. Logistic regression analyses were performed to determine optimal combination of clinical and laboratory abnormalities, characteristic of POEMS syndrome. RESULTS: The diagnostic criteria were statistically defined as the presence of the three major criteria (polyneuropathy (typically demyelinating), monoclonal plasma cell proliferative disorder and elevated vascular endothelial growth factor) and at least two of the four minor criteria (oedema/effusion, skin changes, organomegaly and sclerotic bone lesions), based on best performance by area under the receiver operating characteristic curve analyses. The sensitivity and specificity were 100% and 100%, respectively; the diagnostic accuracy of the proposed criteria was equivalent to somewhat complicated previous criteria. CONCLUSIONS: The statistically defined, simple diagnostic criteria for POEMS syndrome could accelerate early diagnosis and treatment, thereby contribute to better outcome in patients with this serious disease. Prospective larger studies are required to confirm the validity. PMID- 30279214 TI - Vitamin D3 as a potentially modifiable factor in mild cognitive impairment.

Has practice changed in response to new evidence? AB - OBJECTIVES: We investigated trends and regional variation in the rate of arthroscopic knee surgery performed in England from 1997-1998 to 2016-2017. DESIGN: Cross-sectional study of the national hospital episode statistics (HES) for England. METHODS: All hospital episodes for patients undergoing a knee arthroscopy between 1 April 1997 and 31 March 2017 were extracted from HES by procedure code. Age and sex-standardised rates of surgery were calculated using Office for National Statistic population data as the denominator. Trends in the rate of surgery were analysed by procedure both nationally and by Clinical Commissioning Group (CCG). RESULTS: A total of 1 088 872 arthroscopic partial meniscectomies (APMs), 326 600 diagnostic arthroscopies, 308 618 knee washouts and 252 885 chondroplasties were identified (1 759 467 hospital admissions; 1 447 142 patients). The rate of APM increased from a low of 51/100 000 population (95% CI 51 to 52) in 1997-1998 to a peak at 149/100 000 (95% CI 148 to 150) in 2013 2014; then, after 2014-2015, rates declined to 120/100 000 (95% CI 119 to 121) in 2016-2017. Rates of arthroscopic knee washout and diagnostic arthroscopy declined steadily from 50/100 000 (95% CI 49 to 50) and 47/100 000 (95% CI 46 to 47) respectively in 1997-1998, to 4.8/100 000 (95% CI 4.6 to 5.0) and 8.1/100 000 (95% CI 7.9 to 8.3) in 2016-2017. Rates of chondroplasty have increased from a low of 3.2/100 000 (95% CI 3.0 to 3.3) in 1997-1998 to 51/100 000 (95% CI 50.6 to 51.7) in 2016-2017. Substantial regional and age-group variation in practice was detected. In 2016-2017, between 11% (22/207) and 16% (34/207) of CCGs performed at least double the national average rate of each procedure. CONCLUSIONS: Over the last 20 years, and likely in response to new evidence, rates of arthroscopic knee washout and diagnostic arthroscopy have declined by up to 90%. APM rates increased about 130% overall but have declined recently. Rates of chondroplasty increased about 15-fold. There is significant variation in practice, but the appropriate population intervention rate for these procedures remains unknown. PMID- 30279218 TI - First, do "nothing"... and listen. PMID- 30279219 TI - Effects of the '11+ Kids' injury prevention programme on severe injuries in children's football: a secondary analysis of data from a multicentre cluster randomised controlled trial. AB - BACKGROUND: To assess the effects of the injury prevention programme '11+ Kids' on reducing severe injuries in 7 to 13 year old football (soccer) players. METHODS: Football clubs (under-9, under-11 and under-13 age groups) from the Czech Republic, Germany, the Netherlands and Switzerland were cluster-randomised (clubs) into an intervention (INT) and a control group (CON). INT replaced their usual warm-up by '11+ Kids' two times a week. CON followed their regular training regime. Match and training exposure and injury characteristics were recorded and injury incidence rates (IRs) and 95% CIs calculated. For the present analysis, only severe injuries (absence from training/match >=28 days) were considered. Hazard ratios (HR) were calculated using extended Cox models. RESULTS: The overall IR of severe injuries per 1000 football hours was 0.33 (95% CI 0.25 to 0.43) in CON and 0.15 (95% CI 0.10 to 0.23) in INT. There was a reduction of severe overall (HR 0.42, 95% CI 0.24 to 0.72), match (0.41, 0.17 to 0.95) and training injuries (0.42, 0.21 to 0.86) in INT. The injury types that were prevented the most were: other bone injuries 66%, fractures 49% and sprains and ligament injuries 37%. Severe injuries located at the knee (82%), hip/groin (81%), the foot/toe (80%) and the ankle (65%) were reduced tremendously. CONCLUSIONS: '11+ Kids' has a large preventive effect on severe injuries by investing only 15 to 20 min per training session. The present results should motivate coaches to implement effective injury prevention programmes such as the '11+ Kids' in children's football. TRIAL REGISTRATION NUMBER: NCT02222025. PMID- 30279221 TI - ATP binding cassette family A protein 1 determines hexosylceramide and sphingomyelin levels in human and mouse plasma. AB - Sphingolipids, including ceramide, SM, and hexosylceramide (HxCer), are carried in the plasma by lipoproteins. They are possible markers of metabolic diseases, but little is known about their control. We previously showed that microsomal triglyceride transfer protein (MTP) is critical to determine plasma ceramide and SM, but not HxCer, levels. In human plasma and mouse models, we examined possible HxCer-modulating pathways, including the role of ABCA1 in determining sphingolipid plasma concentrations. Compared with control samples, plasma from patients with Tangier disease (deficient in ABCA1) had significantly lower HxCer (-69%) and SM (-40%) levels. Similarly, mice deficient in hepatic and intestinal ABCA1 had significantly reduced HxCer (-79%) and SM (-85%) levels. Tissue specific ablation studies revealed that hepatic ABCA1 determines plasma HxCer and SM levels; that ablation of MTP and ABCA1 in the liver and intestine reduces plasma HxCer, SM, and ceramide levels; and that hepatic and intestinal MTP contribute to plasma ceramide levels, whereas only hepatic MTP modulates plasma SM levels. These results identify the contribution of ABCA1 to plasma SM and HxCer levels and suggest that MTP and ABCA1 are critical determinants of plasma sphingolipid levels.

AB - The lipid composition of human meibomian gland secretions (meibum) has been analyzed using both targeted and untargeted mass spectrometric approaches, each of which has its advantages and disadvantages. Herein we report the results of shotgun lipidomic profiling of human meibum using a new approach that combines the advantages of targeted and untargeted analyses to yield highly sensitive and comprehensive profiles. Samples containing an estimated 7-13 ug (8-16 nL) of human meibum lipids were analyzed using MS/MSall, an untargeted approach for MS/MS. Using MS/MSall with ESI and successive polarity switching, we obtained tandem mass spectra in both modes at every 1 Da step for all ions in the m/z 200 1,200 range. In approximately 12 min, a total of 2 MS spectra and 2,000 MS/MS spectra were acquired for each sample, from which targeted analysis information was extracted. This approach allowed for the comprehensive and highly sensitive detection of meibum lipids, including species low in abundance. Altogether, more than 600 unique lipid molecular species were identified in meibum, 3 times more than previously reported in untargeted analyses of meibum samples. This untargeted MS and MS/MSall approach may be extended to other biological systems for the detection of lipids with sensitivity comparable to targeted analysis. PMID- 30279220 TI - Distinguishing the differences in beta-glycosylceramidase folds, dynamics, and actions informs therapeutic uses. AB - Glycosyl hydrolases (GHs) are carbohydrate-active enzymes that hydrolyze a specific beta-glycosidic bond in glycoconjugate substrates; beta-glucosidases degrade glucosylceramide, a ubiquitous glycosphingolipid. GHs are grouped into structurally similar families that themselves can be grouped into clans. GH1, GH5, and GH30 glycosidases belong to clan A hydrolases with a catalytic (beta/alpha)8 TIM barrel domain, whereas GH116 belongs to clan O with a catalytic (alpha/alpha)6 domain. In humans, GH abnormalities underlie metabolic diseases. The lysosomal enzyme glucocerebrosidase (family GH30), deficient in Gaucher disease and implicated in Parkinson disease etiology, and the cytosol-facing membrane-bound glucosylceramidase (family GH116) remove the terminal glucose from the ceramide lipid moiety. Here, we compare enzyme differences in fold, action, dynamics, and catalytic domain stabilization by binding site occupancy. We also explore other glycosidases with reported glycosylceramidase activity, including human cytosolic beta-glucosidase, intestinal lactase-phlorizin hydrolase, and lysosomal galactosylceramidase. Last, we describe the successful translation of research to practice: recombinant glycosidases and glucosylceramide metabolism modulators are approved drug products (enzyme replacement therapies). Activity based probes now facilitate the diagnosis of enzyme deficiency and screening for compounds that interact with the catalytic pocket of glycosidases. Future research may deepen the understanding of the functional variety of these enzymes and their therapeutic potential. PMID- 30279224 TI - Chromatin conformation and transcriptional activity are permissive regulators of DNA replication initiation in Drosophila. AB - Chromatin structure has emerged as a key contributor to spatial and temporal control over the initiation of DNA replication. However, despite genome-wide correlations between early replication of gene-rich, accessible euchromatin and late replication of gene-poor, inaccessible heterochromatin, a causal relationship between chromatin structure and replication initiation remains elusive. Here, we combined histone gene engineering and whole-genome sequencing in Drosophila to determine how perturbing chromatin structure affects replication initiation. We found that most pericentric heterochromatin remains late replicating in H3K9R mutants, even though H3K9R pericentric heterochromatin is depleted of HP1a, more accessible, and transcriptionally active. These data indicate that HP1a loss, increased chromatin accessibility, and elevated transcription do not result in early replication of heterochromatin. Nevertheless, a small amount of pericentric heterochromatin with increased accessibility replicates earlier in H3K9R mutants. Transcription is de-repressed in these regions of advanced replication but not in those regions of the H3K9R mutant genome that replicate later, suggesting that transcriptional repression may contribute to late replication. We also explored relationships among chromatin, transcription, and replication in euchromatin by analyzing H4K16R mutants. In Drosophila, the X Chromosome gene expression is up-regulated twofold and replicates earlier in XY males than it does in XX females. We found that H4K16R mutation prevents normal male development and abrogates hyperexpression and earlier replication of the male X, consistent with previously established genome-wide correlations between transcription and early replication. In contrast, H4K16R females are viable and fertile, indicating that H4K16 modification is dispensable for genome replication and gene expression. PMID- 30279225 TI - The class I myosin MYO1D binds to lipid and protects against colitis. AB - Myosin ID (MYO1D) is a member of the class I myosin family. We screened 48,649 third generation (G3) germline mutant mice derived from N-ethyl-N-nitrosourea mutagenized grandsires for intestinal homeostasis abnormalities after oral administration of dextran sodium sulfate (DSS). We found and validated mutations in Myo1d as a cause of increased susceptibility to DSS-induced colitis. MYO1D is produced in the intestinal epithelium, and the colitis phenotype is dependent on the nonhematopoietic compartment of the mouse. Moreover, MYO1D appears to couple cytoskeletal elements to lipid in an ATP-dependent manner. These findings demonstrate that MYO1D is needed to maintain epithelial integrity and protect against DSS-induced colitis. PMID- 30279226 TI - Small-molecule BCL6 inhibitor effectively treats mice with non-sclerodermatous chronic graft-versus-host disease. AB - Patient outcomes for steroid-dependent or -refractory cGVHD are poor and only ibrutinib has been FDA approved for this indication. cGVHD is often driven by the germinal center (GC) reaction, in which T follicular helper cells interact with GC B-cells to produce antibodies that are associated with disease pathogenesis. The transcriptional co-repressor BCL6 is a member of the BTB/POZ transcription factor family and master regulator of the immune cells in the GC reaction. We demonstrate that BCL6 expression in both donor T-cells and B-cells is necessary for cGVHD development, pointing to BCL6 as a therapeutic cGVHD target. A small molecule BCL6 inhibitor reversed active cGVHD in a mouse model of multi-organ system injury with bronchiolitis obliterans associated with a robust GC reaction but not in cGVHD mice with scleroderma as the prominent manifestation. For cGVHD patients with antibody-driven cGVHD, targeting of BCL6 represents a new approach with specificity for a master GC regulator that would extend the currently available second-line agents.

PMID- 30279228 TI - Blebbistatin modulates prostatic cell growth and contrapctility through myosin II signaling. AB - To investigate the effect of blebbistatin (BLEB, a selective myosin inhibitor) on regulating contractility and growth of prostate cells and to provide insight into possible mechanisms associated with these actions. BLEB was incubated with cell lines of BPH-1 and WPMY-1, and intraprostatically injected into rats. Cell growth was determined by flow cytometry, and in vitro organ bath studies were performed to explore muscle contractility. Smooth muscle (SM) myosin isoform (SM1/2, SM A/B, and LC17a/b) expression was determined via competitive reverse transcriptase PCR. SM myosin heavy chain (MHC), non-muscle (NM) MHC isoforms (NMMHC-A and NMMHC B), and proteins related to cell apoptosis were further analyzed via Western blotting. Masson's trichrome staining was applied to tissue sections. BLEB could dose-dependently trigger apoptosis and retard the growth of BPH-1 and WPMY-1. Consistent with in vitro effect, administration of BLEB to the prostate could decrease rat prostatic epithelial and SM cells via increased apoptosis. Western blotting confirmed the effects of BLEB on inducing apoptosis through a mechanism involving MLC20 dephosphorylation with down-regulation of Bcl-2 and up-regulation of BAX and cleaved caspase 3. Meanwhile, NMMHC-A and NMMHC-B, the downstream proteins of MLC20, were found significantly attenuated in BPH-1 and WPMY-1 cells, as well as rat prostate tissues. Additionally, BLEB decreased SM cell number and SM MHC expression, along with attenuated phenylephrine-induced contraction and altered prostate SMM isoform composition with up-regulation of SM-B and down regulation of LC17a, favoring a faster contraction. Our novel data demonstrate BLEB regulated myosin expression and functional activity. The mechanism involved MLC20 dephosphorylation and altered SMM isoform composition. PMID- 30279229 TI - Gene Expression Profiling Reveals Aberrant T-cell Marker Expression on Tumor Cells of Waldenstrom's Macroglobulinemia. AB - Purpose: That the malignant clone of Waldenstrom's macroglobulinemia (WM) demonstrates significant intraclonal heterogeneity with respect to plasmacytoid differentiation indicates the mechanistic complexity of tumorigenesis and progression. Identification of WM genes by comparing different stages of B cells may provide novel druggable targets.Experimental Design: The gene expression signatures of CD19+ B cells (BC) and CD138+ plasma cells (PC) from 19 patients with WM were compared with those of BCs from peripheral blood and tonsil and to those of PCs from the marrow of healthy (N-PC) and multiple myeloma donors (MM PC), as well as tonsil (T-PC). Flow cytometry and immunofluorescence were used to examine T-cell marker expression on WM tumor cells.Results: Consistent with defective differentiation, both BCs and PCs from WM cases expressed abnormal differentiation markers. Sets of 55 and 46 genes were differentially expressed in WM-BC and WM-PC, respectively; and 40 genes uniquely dysregulated in WM samples were identified. Dysregulated genes included cytokines, growth factor receptors, and oncogenes not previously implicated in WM or other plasma cell dyscrasias. Interestingly, strong upregulation of both IL6 and IL6R was confirmed. Supervised cluster analysis of PC revealed that marrow-derived WM-PC was either MM-PC-like or T-PC-like, but not N-PC-like. The aberrant expression of T-cell markers was confirmed at the protein level in WM-BC.Conclusions: We showed that comparative microarray profiles allowed gaining more comprehensive insights into the biology of WM. The data presented here have implications for the development of novel therapies, such as targeting aberrant T-cell markers in WM. Clin Cancer Res; 1-9. (c)2018 AACR. PMID- 30279230 TI - Fusion Kinases Identified by Genomic Analyses of Sporadic Microsatellite Instability-High Colorectal Cancers. AB - Purpose: Colorectal cancers with microsatellite instability-high (MSI-H) status, due to mismatch repair deficiency, are associated with poor patient outcomes after relapse. We aimed to identify novel therapeutic targets for them.Experimental Design: We performed MSI analyses of over 2,800 surgically resected colorectal tumors obtained from consecutive patients treated in Japan from 1998 through June 2016. Whole-exome sequencing, transcriptome sequencing, and methylation analyses were performed on 149 of 162 tumors showing MSI in BAT25 and BAT26 loci. We analyzed patient survival times using Bonferroni-adjusted log rank tests.Results: Sporadic MSI-H colorectal cancers with promoter methylation of MLH1 (called MM) had a clinicopathological profile that was distinct from that of colorectal cancers of patients with germline mutations (Lynch syndrome, LS associated) or somatic, Lynch-like mutations in mismatch repair genes. MM tumors had more insertions and deletions and more recurrent mutations in BRAF and RNF43 than LS-associated or Lynch-like MSI-H tumors. Eleven fusion kinases were exclusively detected in MM MSI-H colorectal cancers lacking oncogenic KRAS/BRAF missense mutations and were associated with worse post-relapse prognosis. We developed a simple method to identify MM tumors and applied it to a validation cohort of 28 MSI-H colorectal cancers, identifying 16 MM tumors and 2 fusion kinases.Conclusions: We discovered that fusion kinases are frequently observed among sporadic MM MSI-H colorectal cancers. The new method to identify MM tumors enables us to straightforwardly group MSI-H patients into candidates of LS or fusion kinase carriers. Clin Cancer Res; 1-12. (c)2018 AACR. PMID- 30279231 TI - Loss of RBMS3 Confers Platinum-resistance in Epithelial Ovarian Cancer via Activation of miR-126-5p/beta-catenin/CBP signaling. AB - PURPOSE: The development of resistance to platinum-based chemotherapy remains the unsurmountable obstacle in cancer treatment and consequently leads to tumor relapse. This study aims to investigate the mechanism by which loss of RBMS3 induced chemoresistance in epithelial ovarian cancer (EOC). EXPERIMENTAL DESIGN: Fluorescence in situ hybridization and immunochemistry were used to determine deletion frequency and expression of RBMS3 in 15 clinical EOC tissues and 150 clinicopathologically characterized EOC specimens. The effects of RBMS3 deletion and CBP/beta-catenin antagonist PRI-724 in chemoresistance were examined by clone formation and Annexin V assays in vitro, and by intraperitoneal tumor model in vivo The mechanism by which RBMS3 loss sustained activation of miR-126-5p/beta catenin/CBP signaling and the effects of RBMS3 and miR-126-5p competitively regulating DKK3, AXIN1, BACH1 and NFAT5 was explored using CLIP-seq, RIP, electrophoretic mobility shift and immunoblotting immunofluorescence assays. RESULTS: Loss of RBMS3 in EOC was correlated with the overall and relapse-free survival. Genetic ablation of RBMS3 significantly enhanced, whereas restoration of RBMS3 reduced, the chemoresistance ability of EOC cells both in vitro and in vivo RBMS3 inhibited beta-catenin/CBP signaling through directly associating with and stabilizing multiple negative regulators, including DKK3, AXIN1, BACH1 and NFAT5, via competitively preventing the miR-126-5p-mediated repression of these transcripts. Importantly, co-therapy of CBP/beta-catenin antagonist PRI-724 induced sensitization of RBMS3-deleted EOC to platinum therapy. CONCLUSIONS: Our results demonstrate that genetic ablation of RBMS3 contributes to chemoresistance and PRI-724 may serve as a potential tailored treatment for patients with RBMS3 deleted EOC. PMID- 30279232 TI - Arming an Oncolytic Herpes Simplex Virus Type 1 with a Single-chain Fragment Variable Antibody against PD-1 for Experimental Glioblastoma Therapy. AB - Purpose: Glioblastoma (GBM) is resistant to standard of care. Immune checkpoints inhibitors (such as anti-PD-1 mAbs) efficiently restore antitumor T-cell activity. We engineered a new oncolytic herpes simplex virus (oHSV) expressing a single-chain antibody against PD-1 (scFvPD-1) to evaluate its efficacy in mouse models of GBM.Experimental Design: NG34scFvPD-1 expresses the human GADD34 gene transcriptionally controlled by the Nestin promoter to allow replication in GBM cells and a scFvPD-1 cDNA transcriptionally controlled by the CMV promoter. ELISA assays were performed to detect binding of scFvPD-1 to mouse and human PD-1. In vitro cytotoxicity and replication assays were performed to measure NG34scFvPD-1 oncolysis, and scFvPD-1 expression and secretion were determined. In vivo survival studies using orthotopic mouse GBM models were performed to evaluate the therapeutic potency of NG34scFvPD-1.Results: NG34scFvPD-1-infected GBM cells express and secrete scFvPD-1 that binds mouse PD-1. The introduction of the scFvPD-1 sequence in the viral backbone does not alter the oncolytic properties of NG34scFvPD-1. In situ NG34scFvPD-1 treatment improved the survival with a tail of durable survivorship in 2 syngeneic immunocompetent mouse models of GBM. Mice that survived the first GBM challenge rejected the second challenge of GBM when implanted in the contralateral hemisphere. However, this was not true when athymic mice were employed as the recipients of the second challenge, consistent with the need for an intact immune system to obtain a memory response.Conclusions: NG34scFvPD-1 treatment induces a durable antitumor response in 2 preclinical mouse models of GBM with evidence for antitumor memory.

PMID- 30279233 TI - A Phase I/II Study of Evofosfamide, A Hypoxia-activated Prodrug with or without Bortezomib in Subjects with Relapsed/Refractory Multiple Myeloma. AB - Purpose: The presence of hypoxia in the diseased bone marrow presents a new therapeutic target for multiple myeloma. Evofosfamide (formerly TH-302) is a 2 nitroimidazole prodrug of the DNA alkylator, bromo-isophosphoramide mustard, which is selectively activated under hypoxia. This trial was designed as a phase I/II study investigating evofosfamide in combination with dexamethasone, and in combination with bortezomib and dexamethasone in relapsed/refractory multiple myeloma.Experimental Design: Fifty-nine patients initiated therapy, 31 received the combination of evofosfamide and dexamethasone, and 28 received the combination of evofosfamide, bortezomib, and dexamethasone. Patients were heavily pretreated with a median number of prior therapies of 7 (range: 2-15). All had previously received bortezomib and immunomodulators. The MTD, treatment toxicity, and efficacy were determined.Results: The MTD was established at 340 mg/m2 evofosfamide + dexamethasone with dose-limiting mucositis at higher doses. For the combination of evofosfamide, bortezomib, and dexamethasone, no patient had a dose-limiting toxicity (DLT) and the recommended phase II dose was established at 340 mg/m2 The most common >=grade 3 adverse events (AE) were thrombocytopenia (25 patients), anemia (24 patients), neutropenia (15 patients), and leukopenia (9 patients). Skin toxicity was reported in 42 (71%) patients. Responses included 1 very good partial response (VGPR), 3 partial response (PR), 2 minor response (MR), 20 stable disease (SD), and 4 progressive disease (PD) for evofosfamide + dexamethasone and 1 complete response (CR), 2 PR, 1 MR, 18 SD, and 5 PD for evofosfamide + bortezomib + dexamethasone. Disease stabilization was observed in over 80% and this was reflective of the prolonged overall survival of 11.2 months.Conclusions: Evofosfamide can be administered at 340 mg/m2 twice a week with or without bortezomib. Clinical activity has been noted in patients with heavily pretreated relapsed refractory multiple myeloma. Clin Cancer Res; 1-9. (c)2018 AACR.

PMID- 30279237 TI - Medicaid Expenditures Among Children With Noncomplex Chronic Diseases. AB - BACKGROUND AND OBJECTIVES: Expenditures for children with noncomplex chronic diseases (NC-CDs) are related to disease chronicity and resource use. The degree to which specific conditions contribute to high health care expenditures among children with NC-CDs is unknown. We sought to describe patient characteristics, expenditures, and use patterns of children with NC-CDs with the lowest (<=80th percentile), moderate (81-95th percentile), high (96-99th percentile), and the highest (>=99th percentile) expenditures. METHODS: In this retrospective cross sectional study, we used the 2014 Truven Medicaid MarketScan Database for claims from 11 states. We included continuously enrolled children (age <18 years) with NC-CDs (n = 1 563 233). We describe per member per year (PMPY) spending and use by each expenditure group for inpatient services, outpatient services, and the pharmacy for physical and mental health conditions. K-means clustering was used to identify expenditure types for the highest expenditure group. RESULTS: Medicaid PMPY spending ranged from $1466 (lowest expenditures) to $57 300 (highest expenditures; P < .001); children in the highest expenditure group were diagnosed with a mental health condition twice as often (72.7% vs 34.1%). Cluster analysis was used to identify 3 distinct groups: 83% with high outpatient mental health expenditures (n = 13 033; median PMPY $18 814), 15% with high inpatient expenditures (n = 2386; median PMPY $92 950), and 1% with high pharmacy expenditures (n = 213; median $325 412). Mental health conditions accounted for half of the inpatient diagnoses in the cluster analysis. CONCLUSIONS: One percent of children with the highest expenditures accounted for 20% of Medicaid expenditures in children with NC-CDs; mental health conditions account for a large proportion of aggregate Medicaid spending in children with NC-CDs.

PMID- 30279238 TI - The regenerating family member 3 beta instigates IL-17A-mediated neutrophil recruitment downstream of NOD1/2 signalling for controlling colonisation resistance independently of microbiota community structure. AB - OBJECTIVE: Loss of the Crohn's disease predisposing NOD2 gene results in an intestinal microenvironment conducive for colonisation by attaching-and-effacing enteropathogens. However, it remains elusive whether it relies on the intracellular recruitment of the serine-threonine kinase RIPK2 by NOD2, a step that is required for its activation of the transcription factor NF-kappaB. DESIGN: Colonisation resistance was evaluated in wild type and mutant mice, as well as in ex-germ-free (ex-GF) mice which were colonised either with faeces from Ripk2-deficient mice or with bacteria with similar preferences for carbohydrates to those acquired by the pathogen. The severity of the mucosal pathology was quantified at several time points postinfection by using a previously established scoring. The community resilience in response to infection was evaluated by 16S ribosomal RNA gene sequence analysis. The control of pathogen virulence was evaluated by monitoring the secretion of Citrobacter-specific antibody response in the faeces. RESULTS: Primary infection was similarly outcompeted in ex-GF Ripk2-deficient and control mice, demonstrating that the susceptibility to infection resulting from RIPK2 deficiency cannot be solely attributed to specific microbiota community structures. In contrast, delayed clearance of Citrobacter rodentium and exacerbated histopathology were preceded by a weakened propensity of intestinal macrophages to afford innate lymphoid cell activation. This tissue protection unexpectedly required the regenerating family member 3beta by instigating interleukin (IL) 17A-mediated neutrophil recruitment to the intestine and subsequent phosphorylation of signal transducer and activator of transcription 3. CONCLUSIONS: These results unveil a previously unrecognised mechanism that efficiently protects from colonisation by diarrhoeagenic bacteria early in infection.

PMID- 30279242 TI - HERC2 Facilitates BLM and WRN Helicase Complex Interaction with RPA to Suppress G Quadruplex DNA. AB - BLM and WRN are RecQ DNA helicasesessential for genomic stability. Here, we demonstrate that HERC2, a HECT E3 ligase, is critical for their functions to suppress G-quadruplex (G4) DNA. HERC2 interacted with BLM, WRN, and replication protein A (RPA) complexes during the S-phase of the cell cycle. Depletion of HERC2 dissociated RPA from BLM and WRN complexes and significantly increased G4 formation. Triple depletion revealed that HERC2 has an epistatic relationship with BLM and WRN in their G4-suppressing function. In vitro, HERC2 released RPA onto single-stranded DNA (ssDNA) rather than anchoring onto RPA-coated ssDNA. CRISPR/Cas9-mediated deletion of the catalytic ubiquitin-binding site of HERC2 inhibited ubiquitination of RPA2, caused RPA accumulation in the helicase complexes, and increased G4, indicating an essential role for E3 activity in the suppression of G4. Both depletion of HERC2 and inactivation of E3 sensitized cells to the G4-interacting compounds telomestatin and pyridostatin. Overall, these results indicate that HERC2 is a master regulator of G4 suppression that affects the sensitivity of cells to G4 stabilizers. Given that HERC2 expression is frequently reduced in many types of cancers, G4 accumulation as a result of HERC2 deficiency may provide a therapeutic target for G4 stabilizers.Significance: HERC2 is revealed as a master regulator of G quadruplex, a DNA secondary structure that triggers genomic instability and may serve as a potential molecular target in cancer therapy.Graphical Abstract: http://cancerres.aacrjournals.org/content/canres/78/22/6371/F1.large.jpg Cancer Res; 78(22); 6371-85.

AB - Identification of early-stage pulmonary adenocarcinomas prior to surgery, especially in cases of sub-centimeter cancers, would be clinically important and could provide guidance to clinical decision making. In this study, we developed a deep learning system based on 3D convolutional neural networks and multi-task learning, which automatically predicts tumor invasiveness, together with 3D nodule segmentation masks. The system processes a 3D nodule-centered patch of pre processed CT and learns a deep representation of a given nodule without the need for any additional information. A dataset of 651 nodules with manually segmented voxel-wise masks and pathological labels of atypical adenomatous hyperplasia (AAH), adenocarcinomas in situ (AIS), minimally invasive adenocarcinoma (MIA), and invasive pulmonary adenocarcinoma (IA) was used in this study. We trained and validated our deep learning system on 523 nodules and tested its performance on 128 nodules. An observer study with 2 groups of radiologists, 2 senior and 2 junior, was also investigated. We merged AAH and AIS into one single category AAH AIS, comprising a 3-category classification in our study. The proposed deep learning system achieved better classification performance than the radiologists; in terms of 3-class weighted average F1 score, the model achieved 63.3% while the radiologists achieved 55.6%, 56.6%, 54.3%, and 51.0%, respectively. These results suggest that deep learning methods improve the yield of discriminative results and hold promise in the CADx application domain, which could help doctors work efficiently and facilitate the application of precision medicine.

AB - In the medical literature, the discussion of radial head subluxation (RHS) and nursemaid's elbow may highlight the ability to diagnose and treat the injured patient without obtaining imaging studies. This case reiterates the importance of a thorough physical examination and the use of appropriate imaging when point tenderness is exposed in the injured limb. With point tenderness to the arm, a child with a presumed RHS, otherwise known as nursemaid's elbow, should be evaluated using radiographic imaging to prevent additional potentially destructive physical manipulation of the patient's upper extremity. PMID- 30279244 TI - A Novel Small-Molecule Inhibitor of MRCK Prevents Radiation-Driven Invasion in Glioblastoma. AB - Glioblastoma (GBM) is an aggressive and incurable primary brain tumor that causes severe neurologic, cognitive, and psychologic symptoms. Symptoms are caused and exacerbated by the infiltrative properties of GBM cells, which enable them to pervade the healthy brain and disrupt normal function. Recent research has indicated that although radiotherapy (RT) remains the most effective component of multimodality therapy for patients with GBM, it can provoke a more infiltrative phenotype in GBM cells that survive treatment. Here, we demonstrate an essential role of the actin-myosin regulatory kinase myotonic dystrophy kinase-related CDC42-binding kinase (MRCK) in mediating the proinvasive effects of radiation. MRCK-mediated invasion occurred via downstream signaling to effector molecules MYPT1 and MLC2. MRCK was activated by clinically relevant doses per fraction of radiation, and this activation was concomitant with an increase in GBM cell motility and invasion. Furthermore, ablation of MRCK activity either by RNAi or by inhibition with the novel small-molecule inhibitor BDP-9066 prevented radiation-driven increases in motility both in vitro and in a clinically relevant orthotopic xenograft model of GBM. Crucially, treatment with BDP-9066 in combination with RT significantly increased survival in this model and markedly reduced infiltration of the contralateral cerebral hemisphere.Significance: An effective new strategy for the treatment of glioblastoma uses a novel, anti invasive chemotherapeutic to prevent infiltration of the normal brain by glioblastoma cells.Cancer Res; 78(22); 6509-22.

AB - A 65-year-old woman with Sjogren's syndrome presented with recurrent abdominal distension, constipation, weight loss, orthostatic dizziness, loss of sweating and incomplete emptying of the bladder. Gastrointestinal dilatation but no evidence of malignancy or obstruction was found on CT of the abdomen, oesophagogastroduodenoscopy or colonoscopy. Postvoiding residual urine volume was increased. Antiganglionic acetylcholine receptor antibody was positive. We diagnosed as autoimmune autonomic ganglionopathy. The patient responded to corticosteroid treatment. One year after treatment, she continued to have mild gastrointestinal symptoms, but overall condition was stable without further intervention. PMID- 30279248 TI - Olmesartan-induced enteropathy. AB - Olmesartan-induced enteropathy (OIE) typically presents with a constellation of signs and symptoms including chronic diarrhoea, weight loss and villous atrophy on biopsy. We describe a 68-year-old Caucasian woman with a history of hypothyroidism and hypertension who presented to our hospital with recurrent episodes of acute intermittent diarrhoea, nausea, vomiting, renal failure and 15 lbs weight loss. After an extensive workup, she was diagnosed with possible OIE. Cessation of the offending drug resulted in improvement of clinical symptoms and also hospital admissions for severe diarrhoea reinforcing the diagnosis of OIE. Among the adverse effects of drug therapy, diarrhoea is a relatively frequent adverse event accounting for about 7%. This report serves as an addition to existing literature and to increase the awareness of olmesartan-induced sprue like enteropathy among the primary care physicians and gastroenterologists.

AB - We report a case of Kimura's disease in a 65-year-old woman who presented with generalised itching, abdominal pain, facial puffiness, difficulty in swallowing and loss of appetite. She was found to have generalised lymphadenopathy and a fine-needle aspiration cytology initially done revealed 'reactive lymphadenitis' which was inconclusive. PET-CT done showed features suggestive of lymphoma. Hence, lymph node biopsy was done for confirmation and incidentally after immunohistochemistry staining it turned out to be Kimura's disease. High-dose steroid therapy was started and patient showed dramatic clinical and symptomatic improvement. Kimura's disease almost always presents as cervical lymphadenopathy and usually never causes compressive symptoms. Our patient presented with compressive symptoms and generalised lymphadenopathy which is a rarity. PMID- 30279249 TI - Miliary tuberculosis and herpes pharyngitis after a trip to a developing country: dangers of biologics. AB - The use of biologic drugs has expanded since its introduction in the late 1990s. With growing medical use and newer biologic drugs in development, opportunistic infections like Mycobacterium tuberculosis remain important adverse effects. It carries major public health concerns, yet evidence-based clinical guidelines for more routine interval screening in patients taking immunosuppressants and exposed to tuberculosis (TB) are lacking. We illustrate a case of an elderly Indian-born man living in the USA with psoriatic arthritis who was on adalimumab for 10 years. He presented with disseminated TB and herpes simplex virus type 1 (HSV-1) pharyngitis, a year after an innocuous trip to India. Our case draws attention to the adverse effects of biologic drugs and highlights the importance of regular rescreening for a high-risk population. As the use of biologic treatment increases, physicians must be vigilant in more frequent screening, monitoring and identifying related opportunistic infections, notably M. tuberculosis infections.

AB - In this global health case study, we describe a case of nicotine addiction due to chronic use of electronic cigarettes (e-cigarette) and discuss the beliefs on safety and awareness of their side effects. Many people believe that smoking an e cigarette (vaping) does not have any side effects, especially among teenagers and young adults. Teenagers using an e-cigarette at a young age are twice as likely to try cigarettes later in their life because of nicotine dependency or other social factors. More recent studies have shown long-term systemic side effects of vaping regardless of traditional cigarette smoking history. This report was done for further assessing their risk and to clear out misconceptions of this large scale condition. PMID- 30279253 TI - Troubleshooting a dialysis line: when blue runs red. AB - We present the case of a critically ill woman whose dialysis line was noted to be circulating bright red blood. Located in the right internal jugular vein, the line had previously been working normally with the change occurring shortly after the patient was liberated from positive pressure mechanical ventilation. An arterial malposition was ruled out and subsequent investigations revealed the presence of a left-sided partial anomalous pulmonary venous connection (PAPVC) that had been previously undiagnosed. The identification of a left-sided PAPVC from blood gas measurements taken from a right internal jugular vein dialysis catheter in this case provides an informative opportunity to consider the intricate physiological relationship between the respiratory and cardiovascular systems in critically ill patients requiring invasive procedures and treatments. PMID- 30279254 TI - Diabetic ketoalkalosis: misnomer or undiagnosed variant of diabetic ketoacidosis. AB - Usually, hyperglycaemia crisis presents with acidotic pH, but ketoalkalosis is a rare and unheard entity presenting in diabetic ketoacidosis. We describe three unique cases where the patients present with hyperglycaemia >250 mg/dL, normal or alkalotic pH, and bicarbonate >20 meq/L, which does not meet criteria for diabetic ketoacidosis. However, once these patients were supplemented with intravenous fluids, diagnosis of diabetic ketoacidosis was evident in laboratory analysis. These case series provide a learning opportunity in diagnosing and management of this rare phenomenon. PMID- 30279255 TI - First-line ibrutinib for Bing-Neel syndrome. AB - The authors present a case of an elderly man with a history of Waldenstrom macroglobulinaemia in remission who presented with progressively worsening gait abnormalities and falls for several months. His examination was notable for bilateral lower extremity weakness and an unsteady gait. Brain and spinal MRI showed focal leptomeningeal enhancement in the brain and spinal column. Lumbar puncture was performed and cerebrospinal fluid flow cytometry demonstrated a monoclonal CD5/CD10-negative, CD20-positive B-cell lymphocyte population consistent with a diagnosis of Bing-Neel syndrome. He was started on ibrutinib, an oral Bruton's tyrosine kinase inhibitor, and had marked improvement in his weakness and gait. Repeat imaging 2 months after starting ibrutinib showed improvement in his leptomeningeal enhancement. During subsequent follow-up, he continued to tolerate ibrutinib and had a sustained clinical response.

AB - Patients with a coronary aneurysm alone do not generally exhibit continuous murmurs; however, murmurs may be detected in the presence of a fistula. A 57-year old woman with chest pain was referred to us with a suspected diagnosis of a ruptured sinus of Valsalva aneurysm owing to the presence of a continuous murmur that was detected on physical examination. However, CT revealed a giant right coronary artery aneurysm draining into the right atrium. Consequently, surgery was performed. This case highlights the importance of implementing multiple imaging modalities for adequate differential diagnoses of patients presenting with continuous murmurs.

AB - A 59-year-old man presented with hip pain secondary to metastatic prostate carcinoma affecting multiple sites, including his left acetabulum. The patient's prognosis was good, he was active, independent, with a good quality of life, so was offered surgical reconstruction. The Harrington method involves passing metal rods from the ileum to the ischium and pubis to create a scaffold for hip replacement. This is the gold standard for reconstruction of acetabular metastatic defects. However, this method is prone to failure by medialisation of the construct in the long term. We present our technique of employing a novel modification to the Harrington reconstruction that offers additional support medially with a suprapectineal plate. This construct is strong and durable enough to facilitate immediate weight-bearing and prevent long-term medialisation.

AB - Ehrlichiosis is a rare tickborne illness that can manifest from an asymptomatic, self-limiting disease to a severe presentation with encephalopathy and renal failure. Ehrlichiosis is diagnosed largely based on patient history with confirmatory tests including peripheral blood smear, serology and PCR. Empiric treatment is warranted in patients with suspected tick bites as a delay in treatment can result in multiorgan failure. We discuss a case of ehrlichiosis that presented with the classic pentad of thrombotic thrombocytopenic purpura (TTP). A history of a tick bite was elicited and intravenous doxycycline 100 mg two times a day was initiated. Tick panel results revealed a positive Ehrlichia chaffeensis IgG and IgM titres, consistent with human monocytic ehrlichiosis. Autoimmune workup and antibodies to Borreliaburgdorferi were negative, and ADAMTS13 activity assay results were inconsistent with TTP. The patient completed 14 days of intravenous doxycycline and had an uneventful recovery. PMID- 30279261 TI - Haematometrocolpos due to transverse vaginal septum with distal atretic vagina. PMID- 30279262 TI - Pancake kidney: an incidental finding in a young man. PMID- 30279263 TI - Third-degree burns associated with transcutaneous pacing. AB - A 69-year-old severely obese diabetic woman developed nausea, vomiting and diarrhoea which caused multiple metabolic alterations leading to hypotension and bradycardia due to slow atrioventricular junctional rhythm. Transcutaneous pacing (TCP) was initiated and maintained until the underlying heart rate and blood pressure normalised. TCP gel pads were kept in place prophylactically after pacing was terminated. Gel pads remained attached to the anterior thorax and back for a total of 36 hours. During this time the patient developed third-degree burns at the side of gel pad attachment. With appropriate wound care and after a long hospitalisation, the patient was discharged in stable condition. This case demonstrates that prolonged use of TCP gel pads without frequent replacement may lead to third-degree burns. It also suggest that prophylactic use of TCP gel pads should be avoided.

PMID- 30279267 TI - Tocilizumab in patients with adult-onset still's disease refractory to glucocorticoid treatment: a randomised, double-blind, placebo-controlled phase III trial. AB - OBJECTIVE: To evaluate the efficacy and safety of tocilizumab, an interleukin-6 receptor antibody, in patients with adult-onset Still's disease. METHODS: In this double-blind, randomised, placebo-controlled phase III trial, 27 patients with adult-onset Still's disease refractory to glucocorticoids were randomised to tocilizumab at a dose of 8 mg/kg or placebo given intravenously every 2 weeks during the 12-week, double-blind phase. Patients received open-label tocilizumab for 40 weeks subsequently. The primary outcome was American College of Rheumatology (ACR) 50 response at week 4. The secondary outcomes included ACR 20/50/70, systemic feature score, glucocorticoid dose and adverse events at each point. RESULTS: In the full analysis set, ACR50 response at week 4 was achieved in 61.5% (95% CI 31.6 to 86.1) in the tocilizumab group and 30.8% (95% CI 9.1 to 61.4) in the placebo group (p=0.24). The least squares means for change in systemic feature score at week 12 were -4.1 in the tocilizumab group and -2.3 in the placebo group (p=0.003). The dose of glucocorticoids at week 12 decreased by 46.2% in the tocilizumab group and 21.0% in the placebo group (p=0.017). At week 52, the rates of ACR20, ACR50 and ACR70 were 84.6%, 84.6% and 61.5%, respectively, in both groups. Serious adverse events in all participants who received one dose of tocilizumab were infections, aseptic necrosis in the hips, exacerbation of adult-onset Still's disease, drug eruption and anaphylactic shock. CONCLUSION: The study suggests that tocilizumab is effective in adult onset Still's disease, although the primary endpoint was not met and solid conclusion was not drawn. PMID- 30279269 TI - NF-kappaB-Responsive miRNA-31-5p elicits endothelial dysfunction associated with preeclampsia via downregulation of endothelial nitric oxide synthase. AB - Inflammatory cytokines, including TNF-alpha, were elevated in patients with cardiovascular diseases and are also considered as crucial factors in the pathogenesis of preeclampsia; however, the underlying pathogenic mechanism has not been clearly elucidated. The present study provides novel evidence that TNF alpha leads to endothelial dysfunction associated with hypertension and vascular remodeling in preeclampsia through downregulation of eNOS by NF-kappaB-dependent biogenesis of microRNA (miR)-31-5p, which targets eNOS mRNA. In this study, we found that miR-31-5p was upregulated in sera from patients with preeclampsia and in human endothelial cells treated with TNF-alpha. TNF-alpha-mediated induction of miR-31-5p was blocked by an NF-kappaB inhibitor and NF-kappaB p65 knockdown, but not by MAPK and PI3K inhibitors, indicating that NF-kappaB is essential for biogenesis of miR-31-5p. The treatment of human endothelial cells with TNF-alpha or miR-31-5p mimic decreased endothelial nitric oxide synthase (eNOS) mRNA stability without affecting eNOS promoter activity, resulting in inhibition of eNOS expression and NO/cGMP production through blocking of the functional activity of the eNOS mRNA 3'-untranslated region. Moreover, TNF-alpha and miR-31 5p mimic evoked endothelial dysfunction associated with defects in angiogenesis, trophoblastic invasion, and vasorelaxation in an ex vivo cultured model of human placental arterial vessels, which are typical features of preeclampsia. These results suggest that NF-kappaB-responsive miR-31-5p elicits endothelial dysfunction, hypertension, and vascular remodeling via post-transcriptional downregulation of eNOS and is a molecular risk factor in the pathogenesis and development of preeclampsia.

PMID- 30279270 TI - Crystal structure of a human ubiquitin E1-ubiquitin complex reveals conserved functional elements essential for activity. AB - Ubiquitin (Ub) signaling plays a key regulatory role in nearly every aspect of eukaryotic biology and is initiated by E1 enzymes that activate and transfer Ub to E2 Ub-conjugating enzymes. Despite Ub E1's fundamental importance to the cell and its attractiveness as a target for therapeutic intervention in cancer and other diseases, its only available structural information is derived from yeast orthologs of human ubiquitin-like modifier-activating enzyme 1 (hUBA1). To illuminate structural differences between yeast and hUBA1 structures that might be exploited for the development of small-molecule therapeutics, we determined the first crystal structure of a hUBA1-Ub complex. Using structural analysis, molecular modeling, and biochemical analysis, we demonstrate that hUBA1 shares a conserved overall structure and mechanism with previously characterized yeast orthologs, but displays subtle structural differences, particularly within the active site. Computational analysis revealed four potential ligand-binding hot spots on the surface of hUBA1 that might serve as targets to inhibit hUBA1 at the level of Ub activation or E2 recruitment or that might potentially be used in approaches such as protein-targeting chimeric molecules. Taken together, our work enhances our understanding of the hUBA1 mechanism, provides an improved framework for the development of small-molecule inhibitors of UBA1, and serves as a stepping stone for structural studies that involve the enzymes of the human Ub system at the level of both E1 and E2. PMID- 30279272 TI - Inhibitory Anti-Peroxidasin Antibodies in Pulmonary-Renal Syndromes. AB - BACKGROUND: Goodpasture syndrome (GP) is a pulmonary-renal syndrome characterized by autoantibodies directed against the NC1 domains of collagen IV in the glomerular and alveolar basement membranes. Exposure of the cryptic epitope is thought to occur via disruption of sulfilimine crosslinks in the NC1 domain that are formed by peroxidasin-dependent production of hypobromous acid. Peroxidasin, a heme peroxidase, has significant structural overlap with myeloperoxidase (MPO), and MPO-ANCA is present both before and at GP diagnosis in some patients. We determined whether autoantibodies directed against peroxidasin are also detected in GP. METHODS: We used ELISA and competitive binding assays to assess the presence and specificity of autoantibodies in serum from patients with GP and healthy controls. Peroxidasin activity was fluorometrically measured in the presence of partially purified IgG from patients or controls. Clinical disease severity was gauged by Birmingham Vasculitis Activity Score. RESULTS: We detected anti-peroxidasin autoantibodies in the serum of patients with GP before and at clinical presentation. Enriched anti-peroxidasin antibodies inhibited peroxidasin mediated hypobromous acid production in vitro. The anti-peroxidasin antibodies recognized peroxidasin but not soluble MPO. However, these antibodies did crossreact with MPO coated on the polystyrene plates used for ELISAs. Finally, peroxidasin-specific antibodies were also found in serum from patients with anti MPO vasculitis and were associated with significantly more active clinical disease. CONCLUSIONS: Anti-peroxidasin antibodies, which would previously have been mischaracterized, are associated with pulmonary-renal syndromes, both before and during active disease, and may be involved in disease activity and pathogenesis in some patients. PMID- 30279274 TI - Translational Methods in Nephrology: Individual Treatment Effect Modeling. PMID- 30279273 TI - Dickkopf-3 (DKK3) in Urine Identifies Patients with Short-Term Risk of eGFR Loss. AB - BACKGROUND: The individual course of CKD may vary, and improved methods for identifying which patients will experience short-term eGFR loss are needed. Assessing urinary Dickkopf-3 (DKK3), a stress-induced tubular epithelia-derived profibrotic glycoprotein, may provide information about ongoing tubulointerstitial fibrosis and short-term eGFR loss. METHODS: To investigate urinary DKK3's potential as a biomarker of short-term eGFR loss (over 12 months), we prospectively assessed eGFR and urinary DKK3 levels in patients with CKD of various etiologies at baseline and annual follow-ups. We also measured urinary DKK3 in a general population sample and patients with diagnostic kidney biopsies or IgA nephropathy under treatment. RESULTS: Median urinary DKK3-to-creatinine concentration at baseline was significantly higher in patients with CKD than the general population sample (431 versus 33 pg/mg). In the CKD cohort, having a urinary DKK3-to-creatinine level >4000 pg/mg was independently and significantly associated after multiple adjustments with mean annual decline in eGFR of 7.6% over 12 months. Urinary DKK3 significantly improved prediction of kidney function decline compared with eGFR or albuminuria alone. Urinary DKK3-to-creatinine levels were related to the extent of tubulointerstitial fibrosis in kidney biopsies. In patients with IgA nephropathy, a rise in urinary DKK3 was associated with significant eGFR decline within 6 months, whereas stable or decreasing urinary DKK3 indicated a more favorable course. CONCLUSIONS: Urinary DKK3 levels identify patients at high risk for eGFR decline over the next 12 months regardless of the cause of kidney injury and beyond established biomarkers, potentially providing a tool to monitor CKD progression and assess effects of interventions.

AB - OBJECTIVES: The association between obesity and atrial fibrillation (AF) is well established. We aimed to evaluate the impact of index body mass index (BMI) on AF recurrence at 12 months following catheter ablation using propensity-weighted analysis. In addition, periprocedural complications and fluoroscopy details were examined to assess overall safety in relationship to increasing BMI ranges. METHODS: Baseline, periprocedural and follow-up data were collected on consecutive patients scheduled for AF ablation. There were no specific exclusion criteria. Patients were categorised according to baseline BMI in order to assess the outcomes for each category. RESULTS: Among 3333 patients, 728 (21.8%) were classified as normal (BMI <25.0 kg/m2), 1537 (46.1%) as overweight (BMI 25.5-29.0 kg/m2) and 1068 (32.0%) as obese (BMI >=30.0 kg/m2). Procedural duration and radiation dose were higher for overweight and obese patients compared with those with a normal BMI (p=0.002 and p<0.001, respectively). An index BMI >=30 kg/m2 led to a 1.2-fold increased likelihood of experiencing recurrent AF at 12-months follow-up as compared with overweight patients (HR 1.223; 95% CI 1.047 to 1.429; p=0.011), while no significant correlation was found between overweight and normal BMI groups (HR 0.954; 95% CI 0.798 to 1.140; p=0.605) and obese versus normal BMI (HR 1.16; 95% CI 0.965 to 1.412; p=0.112). CONCLUSIONS: Patients with a baseline BMI >=30 kg/m2 have a higher recurrence rate of AF following catheter ablation and therefore lifestyle modification to target obesity preprocedure should be considered in these patients. PMID- 30279277 TI - Meeting the need for corrective spectacles in visually impaired Chinese school children: the potential of ready-made spectacles. AB - PURPOSE: To assess the potential of ready-made (spherical) spectacles (RMS) in meeting the need for refractive correction in visually impaired children in China. METHODS: Eligible children aged 5-17 years were identified from the three study sites in China. Distance visual acuity was measured with a retroilluminated logarithm of the minimum angle of resolution chart with tumbling E optotypes. Cycloplegic autorefraction was performed on all children using a handheld autorefractor. If uncorrected visual acuity (UCVA) was <=20/40 in either eye, best corrected visual acuity was measured with subjective refractive error. RESULTS : A total of 13 702 children were enumerated from the three studies, with 12 334 (90.0%) having both reliable visual acuity measurements and successful cycloplegia. Among the 12 334 study children, the prevalence of UCVA <=20/40 in the better seeing eye was 16.4% (95% CI 15.0% to 17.8%), with 91.1% (1843) of these improving by >=3 lines of visual acuity with refractive correction. Prevalence was 12.7% (95% CI 11.5% to 13.9%) for UCVA <20/50 with 97.4% (1521) improving by >=3 lines, and 9.38% (95% CI 8.39% to 19.4%) for UCVA <=20/63 with 98.4% (1138) improving by >=3 lines. Depending on the severity of visual impairment, 62.8%-64.0% of children could be accommodated with RMS if not correcting for astigmatism of <=0.75 dioptres and anisometropia of <=0.50 spherical equivalent dioptres. Approximately 87% of children could be accommodated with RMS if astigmatism and anisometropia limits were increased to <=1.25 and <=1.50 dioptres, respectively. CONCLUSIONS: RMS could substantially alleviate visual morbidity in two-thirds or more of visually impaired schoolchildren in China. This cost-effective approach to refractive correction might also be useful in low/middle-income countries with poor access to optometric services. PMID- 30279278 TI - A Bosman ruling for science. PMID- 30279276 TI - Differential GAP requirement for Cdc42-GTP polarization during proliferation and sexual reproduction. AB - The formation of a local zone of Cdc42 GTPase activity, which governs cell polarization in many cell types, requires not only local activation but also switch-off mechanisms. In this study, we identify Rga3, a paralog of Rga4, as a novel Cdc42 GTPase-activating protein (GAP) in the fission yeast Schizosaccharomyces pombe Contrary to Rga4, Rga3 localizes with Cdc42-GTP to sites of polarity. Rga3 is dispensable for cell polarization during mitotic growth, but it limits the lifetime of unstable Cdc42-GTP patches that underlie cell pairing during sexual reproduction, masking a partly compensatory patch wandering motion. In consequence, cells lacking rga3 hyperpolarize and lose out in mating competition. Rga3 synergizes with the Cdc42 GAPs Rga4 and Rga6 to restrict Cdc42-GTP zone sizes during mitotic growth. Surprisingly, triple-mutant cells, which are almost fully round, retain pheromone-dependent dynamic polarization of Cdc42-GTP, extend a polarized projection, and mate. Thus, the requirement for Cdc42-GTP hydrolysis by GAPs is distinct during polarization by intrinsic or extrinsic cues. PMID- 30279279 TI - Co-inhibition of immunoproteasome subunits LMP2 and LMP7 is required to block autoimmunity. AB - Cells of hematopoietic origin express high levels of the immunoproteasome, a cytokine-inducible proteasome variant comprising the proteolytic subunits LMP2 (beta1i), MECL-1 (beta2i), and LMP7 (beta5i). Targeting the immunoproteasome in pre-clinical models of autoimmune diseases with the epoxyketone inhibitor ONX 0914 has proven to be effective. ONX 0914 was previously described as a selective LMP7 inhibitor. Here, we show that PRN1126, developed as an exclusively LMP7 specific inhibitor, has limited effects on IL-6 secretion, experimental colitis, and experimental autoimmune encephalomyelitis (EAE). We demonstrate that prolonged exposure of cells with ONX 0914 leads to inhibition of both LMP7 and LMP2. Co-inhibition of LMP7 and LMP2 with PRN1126 and LMP2 inhibitors LU-001i or ML604440 impairs MHC class I cell surface expression, IL-6 secretion, and differentiation of naive T helper cells to T helper 17 cells, and strongly ameliorates disease in experimental colitis and EAE. Hence, co-inhibition of LMP2 and LMP7 appears to be synergistic and advantageous for the treatment of autoimmune diseases. PMID- 30279281 TI - Cyclosporine Biosynthesis in Tolypocladium inflatum Benefits Fungal Adaptation to the Environment. AB - The cycloundecapeptide cyclosporin A (CsA) was first isolated from the insect pathogenic fungus Tolypocladium inflatum for its antifungal activity and later developed as an immunosuppressant drug. However, the full biosynthetic mechanism of CsA remains unknown and has puzzled researchers for decades. In this study, the biosynthetic gene cluster is suggested to include 12 genes encoding enzymes, including the nonribosomal peptide synthetase (NRPS) (SimA) responsible for assembling the 11 amino acid substrates of cyclosporine and a polyketide synthase (PKS) (SimG) to mediate the production of the unusual amino acid (4R)-4-[(E)-2 butenyl]-4-methyl-l-threonine (Bmt). Individual deletion of 10 genes, isolation of intermediates, and substrate feeding experiments show that Bmt is biosynthesized by three enzymes, including SimG, SimI, and SimJ. The substrate d alanine is catalyzed from l-alanine by alanine racemase SimB. Gene cluster transcription is regulated by a putative basic leucine zipper (bZIP)-type protein encoded by the cluster gene SimL We also found that the cluster cyclophilin (SimC) and transporter (SimD) genes contribute to the tolerance of CsA in the CsA producing fungus. We also found that cyclosporine production could enable the fungus to outcompete other fungi during cocultivation tests. Deletion of the CsA biosynthetic genes also impaired fungal virulence against insect hosts. Taking all the data together, in addition to proposing a biosynthetic pathway of cyclosporines, the results of this study suggest that CsA produced by this fungus might play important ecological roles in fungal environment interactions.IMPORTANCE The cyclopeptide cyclosporin A was first isolated from the filamentous fungus Tolypocladium inflatum showing antifungal activity and was later developed as an immunosuppressant drug. We report the biosynthetic mechanism of cyclosporines that are mediated by a cluster of genes encoding NRPS and PKS controlled by a bZIP-type transcriptional regulator. The two unusual amino acids Bmt and d-Ala are produced by the PKS pathway and alanine racemase, respectively. The cyclophilin and transporter genes jointly contribute to fungal self-protection against cyclosporines. Cyclosporine confers on T. inflatum the abilities to outcompete other fungi in competitive interactions and to facilitate fungal infection of insect hosts, which therefore benefits fungal adaptations to different environments. PMID- 30279280 TI - SsaV Interacts with SsaL to Control the Translocon-to-Effector Switch in the Salmonella SPI-2 Type Three Secretion System. AB - Nonflagellar type III secretion systems (nf T3SSs) form a cell surface needle like structure and an associated translocon that deliver bacterial effector proteins into eukaryotic host cells. This involves a tightly regulated hierarchy of protein secretion. A switch involving SctP and SctU stops secretion of the needle protein. The gatekeeper protein SctW is required for secretion of translocon proteins and controls a second switch to start effector secretion. Salmonella enterica serovar Typhimurium encodes two T3SSs in Salmonella pathogenicity island 1 (SPI-1) and SPI-2. The acidic vacuole containing intracellular bacteria stimulates assembly of the SPI-2 T3SS and its translocon. Sensing the nearly neutral host cytosolic pH is required for effector translocation. Here, we investigated the involvement of SPI-2-encoded proteins SsaP (SctP), SsaU (SctU), SsaV (SctV), and SsaL (SctW) in regulation of secretion. We found that SsaP and SsaU are involved in the first but not the second secretion switch. A random-mutagenesis screen identified amino acids of SsaV that regulate translocon and effector secretion. Single substitutions in subdomain 4 of SsaV or InvA (SPI-1-encoded SctV) phenocopied mutations of their corresponding gatekeepers with respect to translocon and effector protein secretion and host cell interactions. SsaL interacted with SsaV in bacteria exposed to low ambient pH but not after the pH was raised to 7.2. We propose that SsaP and SsaU enable the apparatus to become competent for a secretion switch and facilitate the SsaL-SsaV interaction. This mediates secretion of translocon proteins until neutral pH is sensed, which causes their dissociation, resulting in arrest of translocon secretion and derepression of effector translocation.IMPORTANCE Salmonella Typhimurium is an intracellular pathogen that uses the SPI-2 type III secretion system to deliver virulence proteins across the vacuole membrane surrounding intracellular bacteria. This involves a tightly regulated hierarchy of protein secretion controlled by two molecular switches. We found that SPI-2-encoded proteins SsaP and SsaU are involved in the first but not the second secretion switch. We identify key amino acids of the inner membrane protein SsaV that are required to interact with the so-called gatekeeper protein SsaL and show that the dissociation of SsaV-SsaL causes the second switch, leading to delivery of effector proteins. Our results provide insights into the molecular events controlling virulence-associated type III secretion and suggest a broader model describing how the process is regulated. PMID- 30279284 TI - Ethanolamine Influences Human Commensal Escherichia coli Growth, Gene Expression, and Competition with Enterohemorrhagic E. coli O157:H7. AB - A core principle of bacterial pathogenesis is that pathogens preferentially utilize metabolites that commensal bacteria do not in order to sidestep nutritional competition. The metabolite ethanolamine (EA) is well recognized to play a central role in host adaptation for diverse pathogens. EA promotes growth and influences virulence during host infection. Although genes encoding EA utilization have been identified in diverse bacteria (nonpathogenic and pathogenic), a prevailing idea is that commensal bacteria do not utilize EA to enhance growth, and thus, EA is a noncompetitive metabolite for pathogens. Here, we show that EA augments growth of two human commensal strains of Escherichia coli Significantly, these commensal strains grow more rapidly than, and even outcompete, the pathogen enterohemorrhagic E. coli O157:H7 specifically when EA is provided as the sole nitrogen source. Moreover, EA-dependent signaling is similarly conserved in the human commensal E. coli strain HS and influences expression of adhesins. These findings suggest a more extensive role for EA utilization in bacterial physiology and host-microbiota-pathogen interactions than previously appreciated.IMPORTANCE The microbiota protects the host from invading pathogens by limiting access to nutrients. In turn, bacterial pathogens selectively exploit metabolites not readily used by the microbiota to establish infection. Ethanolamine has been linked to pathogenesis of diverse pathogens by serving as a noncompetitive metabolite that enhances pathogen growth as well as a signal that modulates virulence. Although ethanolamine is abundant in the gastrointestinal tract, the prevailing idea is that commensal bacteria do not utilize EA, and thus, EA utilization has been particularly associated with pathogenesis. Here, we provide evidence that two human commensal Escherichia coli isolates readily utilize ethanolamine to enhance growth, modulate gene expression, and outgrow the pathogen enterohemorrhagic E. coli These data indicate a more complex role for ethanolamine in host-microbiota-pathogen interactions. PMID- 30279283 TI - An Introduced Crop Plant Is Driving Diversification of the Virulent Bacterial Pathogen Erwinia tracheiphila. AB - Erwinia tracheiphila is the causal agent of bacterial wilt of cucurbits, an economically important phytopathogen affecting an economically important phytopathogen affecting few cultivated Cucurbitaceae few cultivated Cucurbitaceae host plant species in temperate eastern North America. However, essentially nothing is known about E. tracheiphila population structure or genetic diversity. To address this shortcoming, a representative collection of 88 E. tracheiphila isolates was gathered from throughout its geographic range, and their genomes were sequenced. Phylogenomic analysis revealed three genetic clusters with distinct hrpT3SS virulence gene repertoires, host plant association patterns, and geographic distributions. Low genetic heterogeneity within each cluster suggests a recent population bottleneck followed by population expansion. We showed that in the field and greenhouse, cucumber (Cucumis sativus), which was introduced to North America by early Spanish conquistadors, is the most susceptible host plant species and the only species susceptible to isolates from all three lineages. The establishment of large agricultural populations of highly susceptible C. sativus in temperate eastern North America may have facilitated the original emergence of E. tracheiphila into cucurbit agroecosystems, and this introduced plant species may now be acting as a highly susceptible reservoir host. Our findings have broad implications for agricultural sustainability by drawing attention to how worldwide crop plant movement, agricultural intensification, and locally unique environments may affect the emergence, evolution, and epidemic persistence of virulent microbial pathogens.IMPORTANCE Erwinia tracheiphila is a virulent phytopathogen that infects two genera of cucurbit crop plants, Cucurbita spp. (pumpkin and squash) and Cucumis spp. (muskmelon and cucumber). One of the unusual ecological traits of this pathogen is that it is limited to temperate eastern North America. Here, we complete the first large-scale sequencing of an E. tracheiphila isolate collection. From phylogenomic, comparative genomic, and empirical analyses, we find that introduced Cucumis spp. crop plants are driving the diversification of E. tracheiphila into multiple lineages. Together, the results from this study show that locally unique biotic (plant population) and abiotic (climate) conditions can drive the evolutionary trajectories of locally endemic pathogens in unexpected ways. PMID- 30279282 TI - Dual Role of a Viral Polymerase in Viral Genome Replication and Particle Self Assembly. AB - Double-stranded RNA (dsRNA) viruses package several RNA-dependent RNA polymerases (RdRp) together with their dsRNA genome into an icosahedral protein capsid known as the polymerase complex. This structure is highly conserved among dsRNA viruses but is not found in any other virus group. RdRp subunits typically interact directly with the main capsid proteins, close to the 5-fold symmetric axes, and perform viral genome replication and transcription within the icosahedral protein shell. In this study, we utilized Pseudomonas phage Phi6, a well-established virus self-assembly model, to probe the potential roles of the RdRp in dsRNA virus assembly. We demonstrated that Phi6 RdRp accelerates the polymerase complex self-assembly process and contributes to its conformational stability and integrity. We highlight the role of specific amino acid residues on the surface of the RdRp in its incorporation during the self-assembly reaction. Substitutions of these residues reduce RdRp incorporation into the polymerase complex during the self-assembly reaction. Furthermore, we determined that the overall transcription efficiency of the Phi6 polymerase complex increased when the number of RdRp subunits exceeded the number of genome segments. These results suggest a mechanism for RdRp recruitment in the polymerase complex and highlight its novel role in virion assembly, in addition to the canonical RNA transcription and replication functions.IMPORTANCE Double-stranded RNA viruses infect a wide spectrum of hosts, including animals, plants, fungi, and bacteria. Yet genome replication mechanisms of these viruses are conserved. During the infection cycle, a proteinaceous capsid, the polymerase complex, is formed. An essential component of this capsid is the viral RNA polymerase that replicates and transcribes the enclosed viral genome. The polymerase complex structure is well characterized for many double-stranded RNA viruses. However, much less is known about the hierarchical molecular interactions that take place in building up such complexes. Using the bacteriophage Phi6 self-assembly system, we obtained novel insights into the processes that mediate polymerase subunit incorporation into the polymerase complex for generation of functional structures. The results presented pave the way for the exploitation and engineering of viral self assembly processes for biomedical and synthetic biology applications. An understanding of viral assembly processes at the molecular level may also facilitate the development of antivirals that target viral capsid assembly. PMID- 30279285 TI - A Member of the Ferlin Calcium Sensor Family Is Essential for Toxoplasma gondii Rhoptry Secretion. AB - Invasion of host cells by apicomplexan parasites such as Toxoplasma gondii is critical for their infectivity and pathogenesis. In Toxoplasma, secretion of essential egress, motility, and invasion-related proteins from microneme organelles is regulated by oscillations of intracellular Ca2+ Later stages of invasion are considered Ca2+ independent, including the secretion of proteins required for host cell entry and remodeling from the parasite's rhoptries. We identified a family of three Toxoplasma proteins with homology to the ferlin family of double C2 domain-containing Ca2+ sensors. In humans and model organisms, such Ca2+ sensors orchestrate Ca2+-dependent exocytic membrane fusion with the plasma membrane. Here we focus on one ferlin that is conserved across the Apicomplexa, T. gondii FER2 (TgFER2). Unexpectedly, conditionally TgFER2 depleted parasites secreted their micronemes normally and were completely motile. However, these parasites were unable to invade host cells and were therefore not viable. Knockdown of TgFER2 prevented rhoptry secretion, and these parasites failed to form the moving junction at the parasite-host interface necessary for host cell invasion. Collectively, these data demonstrate the requirement of TgFER2 for rhoptry secretion in Toxoplasma tachyzoites and suggest a possible Ca2+ dependence of rhoptry secretion. These findings provide the first mechanistic insights into this critical yet poorly understood aspect of apicomplexan host cell invasion.IMPORTANCE Apicomplexan protozoan parasites, such as those causing malaria and toxoplasmosis, must invade the cells of their hosts in order to establish a pathogenic infection. Timely release of proteins from a series of apical organelles is required for invasion. Neither the vesicular fusion events that underlie secretion nor the observed reliance of the various processes on changes in intracellular calcium concentrations is completely understood. We identified a group of three proteins with strong homology to the calcium-sensing ferlin family, which are known to be involved in protein secretion in other organisms. Surprisingly, decreasing the amounts of one of these proteins (TgFER2) did not have any effect on the typically calcium dependent steps in invasion. Instead, TgFER2 was essential for the release of proteins from organelles called rhoptries. These data provide a tantalizing first look at the mechanisms controlling the very poorly understood process of rhoptry secretion, which is essential for the parasite's infection cycle.

PMID- 30279288 TI - Contradictory Results in Microbiome Science Exemplified by Recent Drosophila Research. AB - The bacterium Lactobacillus plantarum is prevalent in animal guts and is widely regarded as beneficial and probiotic. D. Fast et al. (mBio 9:e01114-18, 2018, https://doi.org/10.1128/mBio.01114-18) make the surprising discovery that L. plantarum reduces the life span of Drosophila melanogaster and link this effect with the loss and weakened proliferation of stem cells in the Drosophila gut. These results are apparently at odds with published evidence for beneficial effects of L. plantarum, especially promoting high developmental rates and stimulating stem cell proliferation in young Drosophila The among-study discrepancies highlight the context dependence of many effects of gut microbes on host health, likely influenced by host age and genotype, variation among bacterial strains, and diet. The diversity of results offers an opportunity to elucidate a fundamental mechanism(s) and the circumstances that dictate whether gut bacteria have positive or negative effects on host health. These studies also reinforce the value of Drosophila as an emerging model system for probiotic science.

PMID- 30279286 TI - Proteome Analysis Reveals the Conidial Surface Protein CcpA Essential for Virulence of the Pathogenic Fungus Aspergillus fumigatus. AB - Aspergillus fumigatus is a common airborne fungal pathogen of humans and a significant source of mortality in immunocompromised individuals. Here, we provide the most extensive cell wall proteome profiling to date of A. fumigatus resting conidia, the fungal morphotype pertinent to first contact with the host. Using liquid chromatography-tandem mass spectrometry (LC-MS/MS), we identified proteins within the conidial cell wall by hydrogen-fluoride (HF)-pyridine extraction and proteins exposed on the surface using a trypsin-shaving approach. One protein, designated conidial cell wall protein A (CcpA), was identified by both methods and was found to be nearly as abundant as hydrophobic rodlet layer forming protein RodA. CcpA, an amphiphilic protein, like RodA, peaks in expression during sporulation on resting conidia. Despite high cell wall abundance, the cell surface structure of DeltaccpA resting conidia appeared normal. However, trypsin shaving of DeltaccpA conidia revealed novel surface exposed proteins not detected on conidia of the wild-type strain. Interestingly, the presence of swollen DeltaccpA conidia led to higher activation of neutrophils and dendritic cells than was seen with wild-type conidia and caused significantly less damage to epithelial cells in vitro In addition, virulence was highly attenuated when cortisone-treated, immunosuppressed mice were infected with DeltaccpA conidia. CcpA-specific memory T cell responses were detectable in healthy human donors naturally exposed to A. fumigatus conidia, suggesting a role for CcpA as a structural protein impacting conidial immunogenicity rather than possessing a protein-intrinsic immunosuppressive effect. Together, these data suggest that CcpA serves as a conidial stealth protein by altering the conidial surface structure to minimize innate immune recognition.IMPORTANCE The mammalian immune system relies on recognition of pathogen surface antigens for targeting and clearance. In the absence of immune evasion strategies, pathogen clearance is rapid. In the case of Aspergillus fumigatus, the successful fungus must avoid phagocytosis in the lung to establish invasive infection. In healthy individuals, fungal spores are cleared by immune cells; however, in immunocompromised patients, clearance mechanisms are impaired. Here, using proteome analyses, we identified CcpA as an important fungal spore protein involved in pathogenesis. A. fumigatus lacking CcpA was more susceptible to immune recognition and prompt eradication and, consequently, exhibited drastically attenuated virulence. In infection studies, CcpA was required for virulence in infected immunocompromised mice, suggesting that it could be used as a possible immunotherapeutic or diagnostic target in the future. In summary, our report adds a protein to the list of those known to be critical to the complex fungal spore surface environment and, more importantly, identifies a protein important for conidial immunogenicity during infection.

PMID- 30279292 TI - Use of the STEMI Team for Treatment of Patients With Pulmonary Embolism: A Pilot Study. AB - BACKGROUND: Patients with massive and submassive pulmonary embolism (PE) require rapid identification, triage, and consideration for reperfusion therapy. Use of an existing ST-segment elevation myocardial infarction (STEMI) team and activation protocol may be an effective means to care for these patients. OBJECTIVE: The objective of this analysis was to evaluate a pilot study using the STEMI team and a dedicated PE protocol for treatment of patients with massive and submassive PE. METHODS: From June 2014 to April 2016, a total of 40 patients with massive and submassive PE were evaluated. Baseline demographics, mode of hospital entry (transfer-in, in-hospital, and emergency department [ED] arrival), treatment time intervals (door to computed tomography PE protocol [CTPE], CTPE to invasive pulmonary angiogram, door to treatment time), procedures performed, and in-hospital clinical events were collected. RESULTS: Mean age was 56 +/- 14 years, 17 (42%) were male, and 12 (30%) had a prior history of deep venous thrombosis or PE. Twenty-three patients (57%) had massive PE and 17 patients (43%) had submassive PE. Mode of hospital entry was transfer-in (38%), in hospital (20%), and ED arrival (42%). Four patients (10%) presented with cardiac arrest, 8 patients (20%) required intubation, and 5 patients (12%) required extracorporeal membrane oxygenation. Ten patients (25%) received anticoagulation therapy or placement of inferior vena cava filter, 3 patients (7.5%) received diagnostic pulmonary angiography alone, and 27 patients (67.5%) received endovascular treatment. For patients arriving via the ED, door to CTPE was 4.9 +/ 3.6 hours, CTPE to diagnostic pulmonary angiography was 7.8 +/- 8.5 hours, and door to treatment time was 10.2 +/- 9.0 hours. Endovascular devices utilized included combinations of rheolytic and other thrombectomy devices as well as catheter-directed fibrinolysis. Length of hospital stay was 15 +/- 15 days and in hospital survival rate was 90%. CONCLUSIONS: Use of an existing STEMI team and activation protocol is a feasible method to care for patients with massive and submassive PE. This pilot study demonstrated rapid treatment times with low in hospital mortality. PMID- 30279293 TI - Comparative Effectiveness Study of Drug-Eluting and Bare-Metal Peripheral Artery Stents in Endovascular Femoropopliteal Artery Revascularization. AB - OBJECTIVES: Paclitaxel drug-eluting stents (DESs) have been shown to improve primary patency of femoropopliteal lesions compared to plain balloon angioplasty with provisional bare-metal stents (BMSs) in randomized controlled studies. However, data are lacking on patency outcomes of real-world DES use relative to BMS use. This study compared clinically driven target-lesion revascularization (TLR), target-vessel revascularization (TVR), and target-limb revascularization outcomes at 1 year between DES and BMS treatments in a real-world setting. METHODS: The study identified 174 DES (Zilver PTX; Cook Medical) and 784 BMS femoropopliteal interventions from the available 969 Excellence in Peripheral Artery Disease (XLPAD) registry patients between October 2013 and December 2016. We analyzed both unmatched (174 DES and 784 BMS) and propensity score (PS) matched datasets (174 for each). RESULTS: This study found that patients who underwent DES femoropopliteal endovascular revascularization had significantly lower TLR rates in both unmatched (hazard ratio [HR], 0.57; 95% confidence interval [CI], 0.35-0.91; P=.02) and matched data (HR, 0.50 95% CI, 0.27-0.91; P=.02). The DES group had a 43% lower TVR risk than the BMS group in the PS matched cohort (HR, 0.57; 95% CI, 0.33-0.98; P=.04). Mortality rate in the DES group (5%) was significantly higher than the BMS group in both unmatched (2%; P=.04) and matched groups (1%; P=.046) at 1 year. CONCLUSIONS: Patients treated with DES had higher lesion and vessel patency than BMS after adjusting for confounding, which included complexity of lesion characteristics and operators' clinical decision-making regarding selection of treatment modalities, in femoropopliteal endovascular interventions in a real-world registry. PMID- 30279294 TI - Outcome of Patients Undergoing Transcatheter Aortic Valve Implantation After Prior Balloon Aortic Valvuloplasty. AB - OBJECTIVES: Transcatheter aortic valve implantation (TAVI) is an effective treatment for severe aortic stenosis. Yet, balloon aortic valvuloplasty (BAV) is still occasionally offered to apparently inoperable patients as bridge or destination therapy, with some eventually receiving TAVI. We aimed to determine whether prior BAV would unfavorably impact TAVI. METHODS: The RISPEVA dataset was analyzed to compare the outcomes of non-BAV subjects undergoing TAVI vs those with prior BAV. Outcomes of interest were procedural results, hospital stay, and in-hospital outcomes, including major adverse events. Unadjusted and propensity matched analyses were performed. RESULTS: A total of 1683 patients were included (1541 [91.6%] non-BAV and 142 [8.4%] prior BAV). Device success, procedural success, major adverse events and their individual components were all similar in the two groups, in both unadjusted and propensity-matched analyses. However, non BAV patients had significantly shorter intensive/coronary care unit stay (8.1 +/- 23.0 days vs 13.4 +/- 35.2 days; P=.03) and total hospital stay (12.4 +/- 22.1 days vs 17.2 +/- 32.7 days; P=.02). Similar findings were obtained even in the propensity-matched groups (6.3 +/- 11.9 days vs 13.6 +/- 35.5 days [P=.05] and 10.5 +/- 13.8 days vs 17.4 +/- 33.1 days [P=.03], respectively). No significant interaction was found between device type and prior BAV status. CONCLUSION: BAV continues to offer a palliative solution to patients with unclear or poor prognosis and deemed at too high risk for emergent TAVI or surgery. Subjects undergoing BAV and surviving the post-BAV period can undergo TAVI without a significantly increased risk of in-hospital adverse events in comparison with non BAV patients. PMID- 30279295 TI - Use of Ultrasound-Accelerated, Catheter-Directed Local Thrombolysis for Venous and Arterial Occlusions in a Pediatric Hospital. AB - OBJECTIVES: Acute vascular thrombosis is associated with significant morbidity and mortality in children. Traditional therapies with angioplasty and manual aspiration thrombectomy are described in the pediatric population; however, data regarding the use of ultrasound-assisted catheter-directed thrombolysis in a pediatric hospital are lacking. METHODS: All patients treated at our center with ultrasound-assisted catheter-directed thrombolysis from 2014-2018 were reviewed. RESULTS: Ten patients with systemic venous (n = 5), pulmonary artery (n = 4), and systemic arterial (n = 1) were treated (20 total vessels), including 2 adults post Fontan palliation. The median age was 11.2 years (range, 9 months to 34.2 years) and median weight was 46.6 kg (range, 6.81-01.6 kg). Therapy was not completed in 1 patient. Significant improvement in clot burden/symptomatic improvement was seen in 8 patients (no improvement seen in 1 patient with acute and chronic thrombosis). There were no major bleeding or neurologic complications related to therapy. CONCLUSIONS: The use of ultrasound-assisted catheter-directed thrombolysis in a pediatric center is a valuable modality for treating acute thrombosis with an acceptable safety profile.

(T. majus) or nasturtium is a medicinal plant widespread in the areas with temperate climate, commonly used in culinary and in traditional medicine due to therapeutic properties. In the last few years, various effects of the flowers and leaves of this plant have been studied, but their benefits are not fully known. The aim of the study was to identify the phenolic compounds from T. majus edible flowers in relation with its antioxidant capacity and the antimicrobial activity against different bacteria and Candida albicans. In addition, the impact of natural extract on oxidative stress, inflammation and apoptosis was analysed on human umbilical vein endothelial cells (HUVECs) exposed to normotonic and hypertonic conditions. The major phenolic acids, identified by HPLC-RP with UV detection, were gallic acid, caffeic acid and p-coumaric and predominant flavonoids were quercetin, epicatechin and luteolin. The both fractions of T. majus were rich sources of polyphenols with marked antioxidant activity, evidenced by TEAC or DPPH methods. The extract exhibited a week antibacterial effect on some strains of streptococcus, without antifungal or antibacterial effect on gram negative bacteria. T. majus extract increased the p53 and Bcl-2 expressions and diminished the DNA lesions indicating the protective and antiapoptotic effects in vitro, on endothelial cells exposed to hyperosmotic stress. These experimental findings suggest that T. majus can exert some protection against bacterial infections and reduce apoptosis and DNA lesions in hypertonic conditions. PMID- 30279304 TI - Recent advances in the role of AMP-activated protein kinase in metabolic reprogramming of metastatic cancer cells: targeting cellular bioenergetics and biosynthetic pathways for anti-tumor treatment. AB - Growing data indicate that tumor progression and metastasis is dependent on the reprograming of cellular metabolism. Rapidly growing cancer cells undergo metabolic stress in a harsh microenvironment. AMP-activated protein kinase (AMPK) is an energy sensing factor that regulates bioenergetics and biosynthetic pathways within the cell, but its role under metastasis is in dispute. The best studied phenotype of cancer cells is aerobic glycolysis (the Warburg effect), an increased catabolism of glucose to lactate. However, glycolysis and mitochondrial oxidative phosphorylation may operate simultaneously in cancer cells. Many tumors may switch between these pathways accordingly to the current requirements. The alterations in metabolism of cancer cells combined with the overexpression of oncogenes (c-Myc) and transcription factors (Hypoxia-inducible factor 1a) confer a great advantage to malignant cells to avoid reactive oxygen species induced apoptosis. The determination of the role of AMPK network in metabolic reprogramming of metastatic cancer cells may help to identify the selective molecular targets for efficient anti-cancer therapies. In this review, we discuss the implications of AMPK activation in metabolic reprogramming of cancer cells and we present several potential therapeutic strategies targeting cancer cell metabolism. AMPK activator, biguanide metformin, either alone or in combination with other drugs, may selectively modulate signaling pathways, expresses the chemopreventive potential and can be used in current anti-cancer approaches. However, the ambiguous data suggest that the activation of AMPK may induce multiple effects and thus potential therapeutic anti-cancer approach should be carefully considered in relation to metabolic network of cancer cell signaling and other determinants such tumor stage and origin as well. PMID- 30279305 TI - Hydrogen sulfide modulates gastric acid secretion in rats via involvement of substance P and nuclear factor-kappaB signaling. AB - Hydrogen sulfide (H2S) promotes gastric acid secretion in rats. The present study aimed to test the hypothesis that H2S regulates this response via activating TRPV1 channel and through activation of the nuclear factor-kappaB (NF-kappaB) pathway. Male Wistar rats were randomly divided into the sodium hydrosulfide (NaHS, 100 MUmol/kg b.w.) group, pyrrolidine dithiocarbamate (PDTC, 100 MUmol/kg b.w.) group, PDTC (100 MUmol/kg b.w.) + NaHS (100 MUmol /kg b.w.) group, capsazepine (0.1 mM) + NaHS (100 MUmol /kg b.w.) group and L703606 (0.1 mM) + NaHS (100 MUmol /kg b.w.) group. The acidity of gastric juice before injection and after injection were determined by a pH meter. The results showed that sodium hydrosulfide (NaHS), an exogenous H2S donor, significantly reduced the pH of gastric juice when injected into the enterocoelia. Further, the promotional effect of NaHS on gastric acid secretion could be attenuated by capsazepine, a transient receptor potential vanilloid 1 (TRPV1) antagonist; L703606, a neurokinin 1 (NK1) receptor antagonist; and PDTC, a NF-kappaB inhibitor. The data from these experiments suggest that NaHS exerts an excitatory effect on gastric acid secretion possibly mediated by TRPV1 channel activation in sensory nerve terminals with the consequent release of substance P and in a NF-kappaB dependent manner. PMID- 30279306 TI - Sleep disturbance and disease activity in adult patients with inflammatory bowel diseases. AB - The aim of the study was to identify whether poor quality of sleep is connected to inflammatory bowel disease (IBD) and if so, whether sleep disturbances are related to disease activity. Prospective, observational cohort study was performed. In all enrolled adult patients, the disease activity was assessed by using Crohn's Disease Activity Index (CDAI) for Crohn's disease (CD) and Partial Mayo Score for ulcerative colitis (UC), respectively. All patients were also asked to respond to a questionnaire to define Pittsburgh Quality Sleep Index (PSQI). Sixty-five patients were enrolled in our study: n = 30 with CD and n = 35 with UC. The poor sleep was noted in 78% (40/51) patients with clinically exacerbation and in 35% (5/14) patients in remission (P = 0.002; OR 6.5, 95% confidence interval, 1.8 - 23.6). A global PSQI score of 5 points yielded a sensitivity of 84%, a specificity of 39%, and a positive predictive value of 89% for discriminating participants with exacerbation of IBD from those in clinical remission; PSQI higher than 6 indicates the exacerbation of IBD with 77% sensitivity and 62% specificity. The poorest sleep quality was reported in IBD patients with severe exacerbations (9.1 +/- 2.9). Sleep disturbance was confirmed in adult IBD patients, both in CD and UC. Confirmation of the relationship between sleep abnormalities and IBD may show the new pathway in pathophysiology, course and treatment of IBD. PMID- 30279307 TI - Vasodilating, spasmolytic, inotropic and chronotropic activities of curcuminoids from Curcuma longa in isolated organ preparations of guinea pigs. AB - Turmeric is a yellowish orange spice, widely used in Asian cuisine and obtained from the rhizome of Curcuma longa. It is a mixture of three curcuminoids namely, curcumin, demethoxycurcumin and bisdemethoxycurcumin. Turmeric has been used as a medicinal substance since ancient times for respiratory and gastrointestinal problems. The aim of the present study was to investigate which curcuminoid contributes to the observed pharmacological activities, all three curcuminoids, the major curcumin metabolite tetrahydrocurcumin, and the non-enzymatic curcumin hydrolysis products ferulic acid, feruloyl methane and vanillin were analyzed for spasmolytic, inotropic and chronotropic activity. Furthermore, their uptake in respective tissue samples was also investigated and correlated with activity. Spasmolytic activity was determined in guinea pig ileum, aorta and pulmonary artery. Inotropic and chronotropic activity was determined on guinea pig papillary muscles and right atrium respectively, while tissue uptake was quantified by using high-performance liquid chromatography (HPLC). All the curcuminoids exhibited significant spasmolytic activity with highest EC50 values for bisdemethoxycurcumin (5.8 +/- 0.6 MUM) followed by curcumin (12.9 +/- 0.7 MUM), demethoxycurcumin (16.8 +/- 3 MUM) and tetrahydrocurcumin (22.9 +/- 1.5 MUM). While only demethoxycurcumin was able to significantly relax the pulmonary artery with EC50 value of 15.78 +/- 0.85 MUM. All three curcuminoids showed mild negative chronotropic effects in the isolated right atrium; tetrahydrocurcumin demonstrated no activity. Curcumin and bisdemethoxycurcumin also showed mild positive inotropic effect whereas demethoxycurcumin and tetrahydrocurcumin exhibited weak negative inotropic one. Interestingly, ferulic acid, feruloyl methane and vanillin demonstrated no pharmacologicical activity at all in the various isolated organs. All three curcuminoids and tetrahydrocurcumin showed high uptake into the various tissues where concentrations correlated with pharmacological activity. The results indicate pronounced differences in the in vitro pharmacological activities of curcumin, demethoxycurcumin, bisdemethoxycurcumin and tetrahydrocurcumin which have to be considered in humans after per-oral intake of turmeric powder. PMID- 30279309 TI - Compact convolutional neural networks for classification of asynchronous steady state visual evoked potentials. AB - OBJECTIVE: Steady-state visual evoked potentials (SSVEPs) are neural oscillations from the parietal and occipital regions of the brain that are evoked from flickering visual stimuli. SSVEPs are robust signals measurable in the electroencephalogram (EEG) and are commonly used in brain-computer interfaces (BCIs). However, methods for high-accuracy decoding of SSVEPs usually require hand-crafted approaches that leverage domain-specific knowledge of the stimulus signals, such as specific temporal frequencies in the visual stimuli and their relative spatial arrangement. When this knowledge is unavailable, such as when SSVEP signals are acquired asynchronously, such approaches tend to fail. APPROACH: In this paper, we show how a compact convolutional neural network (Compact-CNN), which only requires raw EEG signals for automatic feature extraction, can be used to decode signals from a 12-class SSVEP dataset without the need for user-specific calibration. MAIN RESULTS: The Compact-CNN demonstrates across subject mean accuracy of approximately 80%, out-performing current state-of-the-art, hand-crafted approaches using canonical correlation analysis (CCA) and Combined-CCA. Furthermore, the Compact-CNN approach can reveal the underlying feature representation, revealing that the deep learner extracts additional phase- and amplitude-related features associated with the structure of the dataset. SIGNIFICANCE: We discuss how our Compact-CNN shows promise for BCI applications that allow users to freely gaze/attend to any stimulus at any time (e.g. asynchronous BCI) as well as provides a method for analyzing SSVEP signals in a way that might augment our understanding about the basic processing in the visual cortex. PMID- 30279308 TI - An endogeous defensive concept, renewed cytoprotection/adaptive cytoprotection: intra(per)-oral/intraastric strong alcohol in rat. Involvement of pentadecapeptide BPC 157 and nitric oxide system. AB - With intra(per)-oral strong alcohol application at the tongue, swallowed, we renewed Robert's stomach cytoprotection/adaptive cytoprotection concept. We assessed strong (96%) alcohol-induced severe or minute lesions in stomach, tongue esophagus-stomach-duodenum lesions, and sphincter pressure (lower esophageal and pyloric) upon administration intragastrically (at 1 h) or intra(per)-orally at the tongue, and swallowed (at 1, 5, 15, 30 min; and 1, 2, 24 h). The assessment also included combined administrations (intra(per)-oral at the tongue, swallowed and intragastric (at 1 h)). Immediate post-alcohol intraperitoneal medication (mg/kg) was the stable gastric pentadecapeptide BPC 157 (0.01, 0.00001; a Robert's cytoprotection mediator; with a therapeutic effect), NOS-blocker L-NAME (5), and NOS-substrate L-arginine (100 mg), (NO-system involvement). After intragastric strong alcohol administration, severe stomach ulcerations appeared along with widespread tongue, esophagus, duodenum redness, and minimal sphincter pressures. By contrast, a particular syndrome (immediate overlapping of cytoprotection/adaptive cytoprotection) (minute gastric lesion or largely attenuated hemorrhagic ulceration, tongue affected, minute esophageal and duodenal lesions, but with intact mucosa; sphincters pressures lowered) appeared after intra(per)-oral administration (1 min-24 h) as well as after combined administrations (intra(per)-oral + intragastric). BPC 157 apparently cured all alcohol-lesions, amplified the spontaneously initiated strong mucosal beneficial effect, rescued sphincter pressures; NO-agents (L-arginine (slight mucosal amelioration) and L-NAME (aggravation)) showed NO-system involvement, but no comparable effects on dropped sphincters pressures. In conclusion, minute gastric lesions (with oral application of strong alcohol at the tongue and swallowed, without, or with intragastric application of strong alcohol) renew and revise Robert's stomach cytoprotection/adaptive cytoprotection concept. The tongue becomes a new initial target, resulting in spontaneous reversal of strong alcohol stomach lesions. BPC 157 therapy functions also within the redirected complexity of Robert's stomach cytoprotection/adaptive cytoprotection concept. PMID- 30279310 TI - Cryo-neutron crystallographic data collection and preliminary refinement of left handed Z-DNA d(CGCGCG). AB - Crystals of left-handed Z-DNA [d(CGCGCG)]2 diffract X-rays to beyond 1 A resolution, feature a small unit cell (~18 * 31 * 44 A) and are well hydrated, with around 90 water molecules surrounding the duplex in the asymmetric unit. The duplex shows regular hydration patterns in the narrow minor groove, on the convex surface and around sugar-phosphate backbones. Therefore, Z-DNA offers an ideal case to test the benefits of low-temperature neutron diffraction data collection to potentially determine the donor-acceptor patterns of first- and second-shell water molecules. Nucleic acid fragments pose challenges for neutron crystallography because water molecules are located on the surface rather than inside sequestered spaces such as protein active sites or channels. Water molecules can be expected to display dynamic behavior, particularly in cases where water is not part of an inner shell and directly coordinated to DNA atoms. Thus, nuclear density maps based on room-temperature diffraction data with a resolution of 1.6 A did not allow an unequivocal determination of the orientations of water molecules. Here, cryo-neutron diffraction data collection for a Z-DNA crystal on the Macromolecular Neutron Diffractometer at the Spallation Neutron Source at Oak Ridge National Laboratory and the outcome of an initial refinement of the structure are reported. A total of 12 diffraction images were recorded with an exposure time of 3.5 h per image, whereby the crystal was static for each diffraction image with a 10 degrees phi rotation between images. Initial refinements using these neutron data indicated the positions and orientations of 30 water molecules within the first hydration shell of the DNA molecule. This experiment constitutes a state-of-the-art approach and is the first attempt to our knowledge to determine the low-temperature neutron structure of a DNA crystal.

AB - Malate dehydrogenase (MDH), a carbohydrate and energy metabolism enzyme in eukaryotes, catalyzes the interconversion of malate to oxaloacetate (OAA) in conjunction with that of nicotinamide adenine dinucleotide (NAD+) to NADH. Three isozymes of MDH have been reported in Saccharomyces cerevisiae: MDH1, MDH2 and MDH3. MDH1 is a mitochondrial enzyme and a member of the tricarboxylic acid cycle, whereas MDH2 is a cytosolic enzyme that functions in the glyoxylate cycle. MDH3 is a glyoxysomal enzyme that is involved in the reoxidation of NADH, which is produced during fatty-acid beta-oxidation. The affinity of MDH3 for OAA is lower than those of MDH1 and MDH2. Here, the crystal structures of yeast apo MDH3, the MDH3-NAD+ complex and the MDH3-NAD+-OAA ternary complex were determined. The structure of the ternary complex suggests that the active-site loop is in the open conformation, differing from the closed conformations in mitochondrial and cytosolic malate dehydrogenases. PMID- 30279311 TI - Conformational changes on substrate binding revealed by structures of Methylobacterium extorquens malate dehydrogenase. AB - Three high-resolution X-ray crystal structures of malate dehydrogenase (MDH; EC 1.1.1.37) from the methylotroph Methylobacterium extorquens AM1 are presented. By comparing the structures of apo MDH, a binary complex of MDH and NAD+, and a ternary complex of MDH and oxaloacetate with ADP-ribose occupying the pyridine nucleotide-binding site, conformational changes associated with the formation of the catalytic complex were characterized. While the substrate-binding site is accessible in the enzyme resting state or NAD+-bound forms, the substrate-bound form exhibits a closed conformation. This conformational change involves the transition of an alpha-helix to a 310-helix, which causes the adjacent loop to close the active site following coenzyme and substrate binding. In the ternary complex, His284 forms a hydrogen bond to the C2 carbonyl of oxaloacetate, placing it in a position to donate a proton in the formation of (2S)-malate.

Peroxiredoxin A (PrxA) from Arabidopsis thaliana belongs to the typical 2-Cys Prx family and is localized in the chloroplast. This article reports the crystal structure of a PrxA C119S mutant refined to 2.6 A resolution. The protein exists as a decamer both in the crystal structure and in solution. The structure is in the reduced state suitable for the approach of peroxide, though conformational changes are needed for the resolving process. PMID- 30279314 TI - Crystal structure of the ribonuclease-P-protein subunit from Staphylococcus aureus. AB - Staphylococcus aureus ribonuclease-P-protein subunit (RnpA) is a promising antimicrobial target that is a key protein component for two essential cellular processes, RNA degradation and transfer-RNA (tRNA) maturation. The first crystal structure of RnpA from the pathogenic bacterial species, S. aureus, is reported at 2.0 A resolution. The structure presented maintains key similarities with previously reported RnpA structures from bacteria and archaea, including the highly conserved RNR-box region and aromatic residues in the precursor-tRNA 5' leader-binding domain. This structure will be instrumental in the pursuit of structure-based designed inhibitors targeting RnpA-mediated RNA processing as a novel therapeutic approach for treating S. aureus infections. PMID- 30279315 TI - Crystal structure of mutant carboxypeptidase T from Thermoactinomyces vulgaris with an implanted S1' subsite from pancreatic carboxypeptidase B. AB - A site-directed mutagenesis method has been used to obtain the G215S/A251G/T257A/D260G/T262D mutant of carboxypeptidase T from Thermoactinomyces vulgaris (CPT), in which the amino-acid residues of the S1' subsite are substituted by the corresponding residues from pancreatic carboxypeptidase B (CPB). It was shown that the mutant enzyme retained the broad, mainly hydrophobic selectivity of wild-type CPT. The mutant containing the implanted CPB S1' subsite was crystallized and its three-dimensional structure was determined at 1.29 A resolution by X-ray crystallography. A comparison of the three-dimensional structures of CPT, the G215S/A251G/T257A/D260G/T262D CPT mutant and CPB showed that the S1' subsite of CPT has not been distorted by the mutagenesis and adequately reproduces the structure of the CPB S1' subsite. The CPB-like mutant differs from CPB in substrate selectivity owing to differences between the two enzymes outside the S1' subsite. Moreover, the difference in substrate specificity between the enzymes was shown to be affected by residues other than those that directly contact the substrate. PMID- 30279316 TI - The novel metallo-beta-lactamase PNGM-1 from a deep-sea sediment metagenome: crystallization and X-ray crystallographic analysis. AB - Metallo-beta-lactamases (MBLs) are present in major Gram-negative pathogens and environmental species, and pose great health risks because of their ability to hydrolyze the beta-lactam rings of antibiotics such as carbapenems. PNGM-1 was the first reported case of a subclass B3 MBL protein that was identified from a metagenomic library from deep-sea sediments that predate the antibiotic era. In this study, PNGM-1 was overexpressed, purified and crystallized. Crystals of native and selenomethionine-substituted PNGM-1 diffracted to 2.10 and 2.30 A resolution, respectively. Both the native and the selenomethionine-labelled PNGM 1 crystals belonged to the monoclinic space group P21, with unit-cell parameters a = 122, b = 83, c = 163 A, beta = 110 degrees . Matthews coefficient (VM) calculations suggested the presence of 6-10 molecules in the asymmetric unit, corresponding to a solvent content of ~31-58%. Structure determination is currently in progress. PMID- 30279318 TI - Comparative structure analysis of the ETSi domain of ERG3 and its complex with the E74 promoter DNA sequence. AB - ERG3 (ETS-related gene) is a member of the ETS (erythroblast transformation specific) family of transcription factors, which contain a highly conserved DNA binding domain. The ETS family of transcription factors differ in their binding to promoter DNA sequences, and the mechanism of their DNA-sequence discrimination is little known. In the current study, crystals of the ETSi domain (the ETS domain of ERG3 containing a CID motif) in space group P41212 and of its complex with the E74 DNA sequence (DNA9) in space group C2221 were obtained and their structures were determined. Comparative structure analysis of the ETSi domain and its complex with DNA9 with previously determined structures of the ERGi domain (the ETS domain of ERG containing inhibitory motifs) in space group P65212 and of the ERGi-DNA12 complex in space group P41212 were performed. The ETSi domain is observed as a homodimer in solution as well as in the crystallographic asymmetric unit. Superposition of the structure of the ETSi domain on that of the ERGi domain showed a major conformational change at the C-terminal DNA-binding autoinhibitory (CID) motif, while minor changes are observed in the loop regions of the ETSi-domain structure. The ETSi-DNA9 complex in space group C2221 forms a structure that is quite similar to that of the ERG-DNA12 complex in space group P41212. Upon superposition of the complexes, major conformational changes are observed at the 5' and 3' ends of DNA9, while the conformation of the core GGA nucleotides was quite conserved. Comparison of the ETSi-DNA9 structure with known structures of ETS class 1 protein-DNA complexes shows the similarities and differences in the promoter DNA binding and specificity of the class 1 ETS proteins. PMID- 30279317 TI - Crystal structures of green fluorescent protein with the unnatural amino acid 4 nitro-L-phenylalanine. AB - The X-ray crystal structures of two superfolder green fluorescent protein (sfGFP) constructs containing a genetically incorporated spectroscopic reporter unnatural amino acid, 4-nitro-L-phenylalanine (pNO2F), at two unique sites in the protein have been determined. Amber codon-suppression methodology was used to site specifically incorporate pNO2F at a solvent-accessible (Asp133) and a partially buried (Asn149) site in sfGFP. The Asp133pNO2F sfGFP construct crystallized with two molecules per asymmetric unit in space group P3221 and the crystal structure was refined to 2.05 A resolution. Crystals of Asn149pNO2F sfGFP contained one molecule of sfGFP per asymmetric unit in space group P4122 and the structure was refined to 1.60 A resolution. The alignment of Asp133pNO2F or Asn149pNO2F sfGFP with wild-type sfGFP resulted in small root-mean-square deviations, illustrating that these residues do not significantly alter the protein structure and supporting the use of pNO2F as an effective spectroscopic reporter of local protein structure and dynamics. PMID- 30279319 TI - Re-refinement of Plasmodium falciparum orotidine 5'-monophosphate decarboxylase provides a clearer picture of an important malarial drug target. AB - The development of antimalarial drugs remains a public health priority, and the orotidine 5'-monophosphate decarboxylase from Plasmodium falciparum (PfOMPDC) has great potential as a drug target. The crystallization of PfOMPDC with substrate bound represents an important advance for structure-based drug-design efforts [Tokuoka et al. (2008), J. Biochem. 143, 69-78]. The complex of the enzyme bound to the substrate OMP (PDB entry 2za1) would be of particular utility in this regard. However, re-refinement of this structure of the Michaelis complex shows that the bound ligand is the product rather than the substrate. Here, the re refinement of a set of three structures, the apo enzyme and two versions of the product-bound form (PDB entries 2za1, 2za2 and 2za3), is reported. The improved geometry and fit of these structures to the observed electron density will enhance their utility in antimalarial drug design. PMID- 30279320 TI - X-ray structure of Arthrobacter globiformis M30 ketose 3-epimerase for the production of D-allulose from D-fructose. AB - The X-ray structure of ketose 3-epimerase from Arthrobacter globiformis M30, which was previously reported to be a D-allulose 3-epimerase (AgD-AE), was determined at 1.96 A resolution. The crystal belonged to the hexagonal space group P6522, with unit-cell parameters a = b = 103.98, c = 256.53 A. The structure was solved by molecular replacement using the structure of Mesorhizobium loti L-ribulose 3-epimerase (MlL-RE), which has 41% sequence identity, as a search model. A hexagonal crystal contained two molecules in the asymmetric unit, and AgD-AE formed a homotetramer with twofold symmetry. The overall structure of AgD-AE was more similar to that of MlL-RE than to the known structures of D-psicose (alternative name D-allulose) 3-epimerases (D-PEs or D AEs), although AgD-AE and MlL-RE have different substrate specificities. Both AgD AE and MlL-RE have long helices in the C-terminal region that would contribute to the stability of the homotetramer. AgD-AE showed higher enzymatic activity for L ribulose than D-allulose; however, AgD-AE is stable and is a unique useful enzyme for the production of D-allulose from D-fructose. PMID- 30279321 TI - Redox manipulation of the manganese metal in human manganese superoxide dismutase for neutron diffraction. AB - Human manganese superoxide dismutase (MnSOD) is one of the most significant enzymes in preventing mitochondrial dysfunction and related diseases by combating reactive oxygen species (ROS) in the mitochondrial matrix. Mitochondria are the source of up to 90% of cellular ROS generation, and MnSOD performs its necessary bioprotective role by converting superoxide into oxygen and hydrogen peroxide. This vital catalytic function is conducted via cyclic redox reactions between the substrate and the active-site manganese using proton-coupled electron transfers. Owing to protons being difficult to detect experimentally, the series of proton transfers that compose the catalytic mechanism of MnSOD are unknown. Here, methods are described to discern the proton-based mechanism using chemical treatments to control the redox state of large perdeuterated MnSOD crystals and subsequent neutron diffraction. These methods could be applicable to other crystal systems in which proton information on the molecule in question in specific chemical states is desired. PMID- 30279322 TI - Fluorescence Tumor-Imaging Using a Thermo-Responsive Molecule with an Emissive Aminoquinoline Derivative. AB - We synthesized (2,4-trifluoromethyl-7-N-bis(2,5,8,11-tetraoxatridecane-13-yl) aminoquinoline) TFMAQ-diEg4, an emissive aminoquinoline derivative that incorporated two tetraethyleneglycol chains into an amino group. TFMAQ-diEg4 showed fluorescence and thermo-responsive properties accompanied by a lower critical solution temperature (LCST), due to the introduction of the oligoethylene glycol chain. This thermo-responsive LCST behavior occurred at the border of a cloud point. Below and above the cloud point, self-assemblies of 6-7 nm nanoparticles and ~2000-nm microparticles were observed, in vitro. In addition, TFMAQ-diEg4 showed a high solubility, over 20 mM for aqueous solution, in vivo, which not only prevented thrombosis but also allowed various examinations, such as single intravenous administration and intravenous drips. Intravenous administration of TFMAQ-diEg4, to tumor-bearing, mice led to the accumulation of the molecule in the tumor tissue, as observed by fluorescence imaging. A subset of mice was treated with local heat around their tumor tissue and an intravenous drip of TFMAQ-diEg4, which led to a high intensity of TFMAQ diEg4 emission within the tumor tissue. Therefore, we revealed that TFMAQ-diEg4 was useful as a fluorescence probe with thermo-responsive properties. PMID- 30279323 TI - Optimization of Polyphenol Extraction from Allium ampeloprasum var. porrum through Response Surface Methodology. AB - Allium ampeloprasum var. porrum has been recognized as a rich source of secondary metabolites, including phenolic acids, flavonoids and flavonoid polymers (proanthocyanidins or condensed tannins), with related health benefits. Both parts of Allium ampeloprasum var. porrum (white bulb and pseudostem) are traditionally consumed either as a vegetable or as a condiment in many Mediterranean countries. The aim of the present study was to optimize the extraction conditions of polyphenols from white leek stem and green leek leaf by implementing a Box-Behnken design (BBD). The optimization considered basic factors affecting extraction efficiency, including extraction time, solvent to plant material ratio and solvent mixture composition. Maximum polyphenol yield was achieved at an extraction time of 80 and 100 min for white leek stem and green leek leaf extracts respectively, solvent to plant material ratio of 5:1 (v/w) and methanol to water ratio of 40:60 (v/v), for both leek extracts. Interestingly, higher total phenolic content was found in green leek leaf extracts compared to white leek stem extracts, due to a possible relationship between polyphenol production and sunlight radiation. High correlation values were also observed between total phenolic content and antioxidant-antiradical activity of optimized leek extracts. PMID- 30279325 TI - An Alternative Perspective for the Theory of Biological Control. AB - Importation biological control represents the planned introduction of a specialist natural enemy from the region of origin of an invasive pest or weed. For this study, the author considered why attempts to develop a predictive theory for biological control have been misguided and what future directions might be more promising and effective. Despite considerable interest in the theory of consumer-resource population dynamics, such theory has contributed little to improvements in the success of biological control due to a focus on persistence and equilibrium dynamics rather than establishment and impact. A broader consideration of invasion biology in addition to population ecology offers new opportunities for a more inclusive theory of biological control that incorporates the demographic and genetic processes that more specifically address the establishment and impact of introduced natural enemies. The importance of propagule size and genetic variance for successful establishment, and of contributions to host population growth, relative population growth rates, interaction strength, and coevolution for suppression of host abundance are discussed as promising future directions for a theory of biological control. PMID- 30279324 TI - Preparation and Enrichment Properties of Magnetic Dodecyl Chitosan/Silica Composite for Emerging Bisphenol Contaminants. AB - Magnetic dodecyl chitosan/silica composite was synthesized and characterized for the enrichment of emerging bisphenol contaminants. The result demonstrated that bispehnol A, bisphenol AF, bisphenol F, and bisphenol S can be efficiently extracted via the resulting composite from aqueous solution. The adsorption rate of four investigated bisphenols on the resulting composite was achieved in the range of 87-99% within 15 min. Bispehnol A was taken as a representative adsorbate to investigate the adsorption studies in detail. The hydrophobic interaction was proposed as the principal mechanism for the adsorption of BPs. The satisfactory reusability of the resulting composite can be quickly achieved by magnetic separation technologies. Magnetic dodecyl chitosan/silica composite has a potential to be applied as a type of efficient and easily recyclable sorbent for the removal of trace organic pollutants from aqueous sample. PMID- 30279326 TI - A Water-Soluble Extract from Actinidia arguta Ameliorates Psoriasis-Like Skin Inflammation in Mice by Inhibition of Neutrophil Infiltration. AB - Psoriasis is a chronic inflammatory disease with complex etiology involving multiple factors. Current treatment methods are highly limited and there is a strong need for the development of safer and efficacious agents. We have previously shown that a water-soluble extract derived from hardy kiwifruit Actinidia arguta, called PG102, shows potent anti-inflammatory effects. Based on its reported biological activities, the effects of PG102 were examined on imiquimod-induced psoriasis-like skin inflammation. Our results showed that topical application of PG102 ameliorates clinical symptoms of psoriasis, reducing skin thickness and Interleukin (IL)-17A level in draining lymph nodes without causing any adverse effects. Treatment with PG102 on cytokine-stimulated HaCaT cells suppressed hyperproliferation and downregulated the expression of various chemokines and antimicrobial peptides known to induce neutrophil infiltration. These anti-inflammatory activities of PG102 were mediated via inhibition of NF kappaB and signal transducer of activation (STAT) signaling. We also found decreased neutrophil chemotaxis both in vitro and in vivo. Taken together, PG102 has potential as a safe and effective reagent for the treatment of psoriasis. PMID- 30279327 TI - An Improved Method for Prediction of Cancer Prognosis by Network Learning. AB - Accurate identification of prognostic biomarkers is an important yet challenging goal in bioinformatics. Many bioinformatics approaches have been proposed for this purpose, but there is still room for improvement. In this paper, we propose a novel machine learning-based method for more accurate identification of prognostic biomarker genes and use them for prediction of cancer prognosis. The proposed method specifies the candidate prognostic gene module by graph learning using the generative adversarial networks (GANs) model, and scores genes using a PageRank algorithm. We applied the proposed method to multiple-omics data that included copy number, gene expression, DNA methylation, and somatic mutation data for five cancer types. The proposed method showed better prediction accuracy than did existing methods. We identified many prognostic genes and their roles in their biological pathways. We also showed that the genes identified from different omics data were complementary, which led to improved accuracy in prediction using multi-omics data. PMID- 30279328 TI - Dietary Iron Overload Abrogates Chemically-Induced Liver Cirrhosis in Rats. AB - Chronic liver disease is an intractable disease, which can progress to cirrhosis and hepatocellular carcinoma. Hepatic iron overload is considered to be involved in the progression of chronic liver diseases; however, the mechanism remains to be elucidated. Here we investigate the role of dietary iron overload using chemically-induced liver cirrhosis model. Rats were fed a high-iron or standard diet and were injected intraperitoneally with thioacetamide (TAA) or saline twice a week for 20 weeks. Rats with TAA treatment (TAA group) had progressive liver cirrhosis characterized by persistent hepatocellular injury, mononuclear cell inflammation and bridging fibrosis; these lesions were markedly reduced in rats with iron feeding and TAA treatment (Fe-TAA group). Rats with iron feeding alone (Fe group) had no evidence of liver injury. Hepatic expression of cleaved caspase 3, but not phospho-RIP3, was decreased in Fe-TAA group compared with that in TAA group. The number of TUNEL-positive (terminal deoxynucleotidyl transferase dUTP nick end labeling) apoptotic hepatocytes was lower in the Fe-TAA group than in the TAA group. Hepatic xenobiotic metabolism and lipid peroxidation were shown to be less related to the abrogation of liver cirrhosis. Our results suggested that dietary hepatic iron overload abrogates chemically-induced liver cirrhosis in rats, which could partly involve decreased hepatocellular apoptosis. PMID- 30279329 TI - Novel Anti-Obesity Properties of Palmaria mollis in Zebrafish and Mouse Models. AB - (1) Background: The red seaweed Palmaria mollis (PM), which has a bacon-like taste, is increasingly being included in Western diets. In this study, we evaluate anti-obesity effects of PM using diet-induced obese (DIO) zebrafish and mice models. (2) Methods: We fed PM-containing feed to DIO-zebrafish and mice, and evaluated the anti-obesity effects We also analyzed gene expression changes in their liver and visceral adipose tissues (VAT). (3) Results: PM ameliorated several anti-obesity traits in both animals, including dyslipidaemia, hepatic steatosis, and visceral adiposity. In liver tissues of DIO-zebrafish and mice, PM upregulated gene expressions involved in peroxisome proliferator-activated receptor alpha (PPARA) pathways, and downregulated peroxisome proliferator activated receptor gamma (PPARG) pathways, suggesting that the lipid-lowering effect of PM might be caused by activation of beta-oxidation and inhibition of lipogenesis. In VAT, PM downregulated genes involved in early and late adipocyte differentiation in zebrafish, but not in mice. (4) Conclusions: We have demonstrated that PM can prevent hepatic steatosis and visceral adiposity for the first time. Dietary supplementation of PM as a functional food may be suitable for obesity prevention and reduction in the prevalence of obesity-related diseases. PMID- 30279330 TI - MicroRNA-Attenuated Virus Vaccines. AB - Live-attenuated vaccines are the most effective way to establish robust, long lasting immunity against viruses. However, the possibility of reversion to wild type replication and pathogenicity raises concerns over the safety of these vaccines. The use of host-derived microRNAs (miRNAs) to attenuate viruses has been accomplished in an array of biological contexts. The broad assortment of effective tissue- and species-specific miRNAs, and the ability to target a virus with multiple miRNAs, allow for targeting to be tailored to the virus of interest. While escape is always a concern, effective strategies have been developed to improve the safety and stability of miRNA-attenuated viruses. In this review, we discuss the various approaches that have been used to engineer miRNA-attenuated viruses, the steps that have been taken to improve their safety, and the potential use of these viruses as vaccines. PMID- 30279331 TI - Artificial Intelligence in Drug Design. AB - Artificial Intelligence (AI) plays a pivotal role in drug discovery. In particular artificial neural networks such as deep neural networks or recurrent networks drive this area. Numerous applications in property or activity predictions like physicochemical and ADMET properties have recently appeared and underpin the strength of this technology in quantitative structure-property relationships (QSPR) or quantitative structure-activity relationships (QSAR). Artificial intelligence in de novo design drives the generation of meaningful new biologically active molecules towards desired properties. Several examples establish the strength of artificial intelligence in this field. Combination with synthesis planning and ease of synthesis is feasible and more and more automated drug discovery by computers is expected in the near future. PMID- 30279332 TI - Impact of Agaricus bisporus Mushroom Consumption on Gut Health Markers in Healthy Adults. AB - Eating Agaricus bisporus mushrooms may impact gut health, because they contain known prebiotics. This study assessed mushroom consumption compared to meat on gastrointestinal tolerance, short chain fatty acid (SCFA) production, laxation, and fecal microbiota. A randomized open-label crossover study was conducted in healthy adults (n = 32) consuming protein-matched amounts of mushrooms or meat twice daily for ten days. Breath hydrogen measures were taken on day one, and gastrointestinal tolerance was evaluated throughout treatments. Fecal sample collection was completed days 6-10, and samples were assessed for bacterial composition, SCFA concentrations, weight, pH, and consistency. There were no differences in breath hydrogen, stool frequency, consistency, fecal pH, or SCFA concentrations between the two diets. The mushroom diet led to greater overall gastrointestinal symptoms than the meat diet on days one and two. The mushroom rich diet resulted in higher average stool weight (p = 0.002) and a different fecal microbiota composition compared to the meat diet, with greater abundance of Bacteroidetes (p = 0.0002) and lower abundance of Firmicutes (p = 0.0009). The increase in stool weight and presence of undigested mushrooms in stool suggests that mushroom consumption may impact laxation in healthy adults. Additional research is needed to interpret the health implications of fecal microbiota shifts with mushroom feeding. PMID- 30279333 TI - Effects of Whole Milk Supplementation on Gut Microbiota and Cardiometabolic Biomarkers in Subjects with and without Lactose Malabsorption. AB - The aim of this study was to compare the impact of whole milk supplementation on gut microbiota and cardiometabolic biomarkers between lactose malabsorbers (LM) and absorbers (LA). We performed a pair-wise intervention study of 31 LM and 31 LA, 1:1 matched by age, sex, body mass index, and daily dairy intake. Subjects were required to add 250 mL/day whole milk for four weeks in their routine diet. At the beginning and the end of the intervention period, we collected data on gut microbiota and cardiometabolic biomarkers. Whole milk supplementation significantly increased Actinobacteria (P < 0.01), Bifidobacterium (P < 0.01), Anaerostipe (P < 0.01), and Blautia (P = 0.04), and decreased Megamonas (P = 0.04) in LM, but not LA. Microbial richness and diversity were not affected. The fecal levels of short-chain fatty acids (SCFAs) remained stable throughout the study. Body fat mass (P < 0.01) and body fat percentage (P < 0.01) reduced in both groups, but the changes did not differ between groups. No significant differences in other cardiometabolic markers were found between LM and LA. When compared with LA, whole milk supplementation could alter the intestinal microbiota composition in LM, without significant changes in fecal SCFAs and cardiometabolic biomarkers. PMID- 30279334 TI - Comparison on Photosynthesis and Antioxidant Defense Systems in Wheat with Different Ploidy Levels and Octoploid Triticale. AB - To investigate the evolutionary differences of wheat with different ploidy levels and octoploid Triticale, photosynthetic capacity, and antioxidant defenses system were compared within and between diploid, tetraploid and hexaploid wheat, and octoploid Triticale seedlings. The results showed that seed germination rate, chlorophyll content, and photochemical activity of photosystems, and the activities of antioxidative enzymes in hexaploid wheat and octoploid Triticale were significantly higher than in diploid and tetraploid wheat. Compared to other two wheat species and octoploid Triticale, hexaploid wheat presented lower levels of reactive oxygen species (ROS). Furthermore, we found that the levels of photosystem II reaction center protein D1, light-harvesting complex II b4 (CP29), and D subunit of photosystem I (PsaD) in diploid wheat were significantly lower compared with hexaploid wheat and octoploid Triticale. Taken together, we concluded that hexaploid wheat and octoploid Triticale have higher photosynthetic capacities and better antioxidant systems. These findings indicate that different ploidy levels of chromosome probably play an important regulatory role in photosystems and antioxidative systems of plants. PMID- 30279336 TI - Isolation and Identification of the Five Novel Flavonoids from Genipa americana Leaves. AB - Genipa americana is a medicinal plant popularly known as "jenipapo", which occurs in Brazil and belongs to the Rubiaceae family. It is a species widely distributed in the tropical Central and South America, especially in the Cerrado biome. Their leaves and fruits are used as food and popularly in folk medicine to treat anemias, as an antidiarrheal, and anti-syphilitic. Iridoids are the main secondary metabolites described from G. americana, but few studies have been conducted with their leaves. In this study, the aim was to chemical approach for identify the main compounds present at the extract of G. americana leaves. The powdered leaves were extracted by maceration with EtOH: water (70:30, v/v), following liquid-liquid partition with petroleum ether, chloroform, ethyl acetate and n-butanol. A total of 13 compounds were identified. In addition three flavonoids were isolated from the ethyl acetate fraction: quercetin-3-O robinoside (GAF 1), kaempferol-3-O-robinoside (GAF 2) and isorhamnetin-3-O robinoside (GAF 3) and, from n-butanol fraction more two flavonoids were isolated, kaempferol-3-O-robinoside-7-O-rhamnoside (robinin) (GAF 4) and isorhamnetin-3-O-robinoside-7-rhamnoside (GAF 5). Chemical structures of these five flavonoids were elucidated using spectroscopic methods (MS, 1H and 13C-NMR 1D and 2D). These flavonoids glycosides were described for the first time in G. americana. PMID- 30279335 TI - Nutrigenetic Contributions to Dyslipidemia: A Focus on Physiologically Relevant Pathways of Lipid and Lipoprotein Metabolism. AB - Cardiovascular disease (CVD) remains the number one cause of death worldwide, and dyslipidemia is a major predictor of CVD mortality. Elevated lipid concentrations are the result of multiple genetic and environmental factors. Over 150 genetic loci have been associated with blood lipid levels. However, not all variants are present in pathways relevant to the pathophysiology of dyslipidemia. The study of these physiologically relevant variants can provide mechanistic understanding of dyslipidemia and identify potential novel therapeutic targets. Additionally, dietary fatty acids have been evidenced to exert both positive and negative effects on lipid profiles. The metabolism of both dietary and endogenously synthesized lipids can be affected by individual genetic variation to produce elevated lipid concentrations. This review will explore the genetic, dietary, and nutrigenetic contributions to dyslipidemia. PMID- 30279337 TI - High Throughput Identification of Antihypertensive Peptides from Fish Proteome Datasets. AB - Antihypertensive peptides (AHTPs) are a group of small peptides with the main role to block key enzymes or receptors in the angiotensin genesis pathway. A great number of AHTPs have been isolated or digested from natural food resources; however, comprehensive studies on comparisons of AHTPs in various species from the perspective of big data are rare. Here, we established a simplified local AHTP database, and performed in situ mapping for high throughput identification of AHTPs with high antihypertensive activity from high-quality whole proteome datasets of 18 fish species. In the 35 identified AHTPs with reported high activity, we observed that Gly-Leu-Pro, Leu-Pro-Gly, and Val-Ser-Val are the major components of fish proteins, and AHTP hit numbers in various species demonstrated a similar distributing pattern. Interestingly, Atlantic salmon (Salmo salar) is in possession of far more abundant AHTPs compared with other fish species. In addition, collagen subunit protein is the largest group with more matching AHTPs. Further exploration of two collagen subunits (col4a5 and col8a1) in more fish species suggested that the hit pattern of these conserved proteins among teleost is almost the same, and their phylogeny is consistent with the evolution of these fish species. In summary, our present study provides basic information for the relationship of AHTPs with fish proteins, which sheds light on rapid discovery of marine drugs or food additives from fish protein hydrolysates to alleviate hypertension. PMID- 30279338 TI - The Microbiome and Radiation Induced-Bowel Injury: Evidence for Potential Mechanistic Role in Disease Pathogenesis. AB - Radiotherapy has played a major role in both the curative and palliative treatment of cancer patients for decades. However, its toxic effect to the surrounding normal healthy tissue remains a major drawback. In cases of intra abdominal and/or pelvic malignancy, healthy bowel is inevitably included in the radiation field, causing undesirable consequences that subsequently manifest as radiation-induced bowel injury, which is associated with significant morbidity and mortality. The pathophysiology of radiation-induced bowel injury is poorly understood, although we now know that it derives from a complex interplay of epithelial injury and alterations in the enteric immune, nervous, and vascular systems in genetically predisposed individuals. Furthermore, evidence supporting a pivotal role for the gut microbiota in the development of radiation-induced bowel injury has been growing. In this review, we aim to appraise our current understanding of radiation-induced bowel injury and the role of the microbiome in its pathogenesis as well as prevention and treatment. Greater understanding of the relationship between the disease mechanism of radiation-induced bowel injury and gut microbiome might shed light on potential future prevention and treatment strategies through the modification of a patient's gut microbiome.

AB - Bimetallic nanoparticles are of interest since they lead to many interesting electrical, chemical, catalytic, and optical properties. They are particularly important in the field of catalysis since they show superior catalytic properties than their monometallic counterparts. The structures of bimetallic nanoparticles depend mainly on the synthesis conditions and the miscibility of the two components. In this work, PdPt alloyed-bimetallic nanoparticles (NPs) were synthesized through the polyol method, and characterized using spherical aberration (Cs) corrected scanning transmission electron microscopy (STEM). High angle annular dark-field (HAADF)-STEM images of bimetallic nanoparticles were obtained. The contrast of images shows that nanoparticles have an alloy structure with an average size of 8.2 nm. Together with the characterization of nanoparticles, a systematic molecular dynamics simulations study focused on the structural stability and atomic surface segregation trends in 923-atom PdPt alloyed-bimetallic NPs was carried out.

AB - Patterned hair loss (PHL) affects around 50% of the adult population worldwide. The negative impact that this condition exerts on people's life quality has boosted the appearance of over-the-counter products endowed with hair-promoting activity. Nutraceuticals enriched in polyphenols have been recently shown to promote hair growth and counteract PHL. Malus pumila Miller cv. Annurca is an apple native to Southern Italy presenting one of the highest contents of Procyanidin B2. We have recently shown that oral consumption of Annurca polyphenolic extracts (AAE) stimulates hair growth, hair number, hair weight and keratin content in healthy human subjects. Despite its activity, the analysis of the molecular mechanism behind its hair promoting effect is still partially unclear. In this work we performed an unprecedented metabolite analysis of hair follicles (HFs) in mice topically treated with AAE. The metabolomic profile, based on a high-resolution mass spectrometry approach, revealed that AAE re programs murine HF metabolism. AAE acts by inhibiting several NADPH dependent reactions. Glutaminolysis, pentose phosphate pathway, glutathione, citrulline and nucleotide synthesis are all halted in vivo by the treatment of HFs with AAE. On the contrary, mitochondrial respiration, beta-oxidation and keratin production are stimulated by the treatment with AAE. The metabolic shift induced by AAE spares amino acids from being oxidized, ultimately keeping them available for keratin biosynthesis. PMID- 30279341 TI - Maternal Melatonin Therapy Attenuates Methyl-Donor Diet-Induced Programmed Hypertension in Male Adult Rat Offspring. AB - Although pregnant women are advised to consume methyl-donor food, some reports suggest an adverse outcome. We investigated whether maternal melatonin therapy can prevent hypertension induced by a high methyl-donor diet. Female Sprague Dawley rats received either a normal diet, a methyl-deficient diet (L-MD), or a high methyl-donor diet (H-MD) during gestation and lactation. Male offspring were assigned to four groups (n = 7-8/group): control, L-MD, H-MD, and H-MD rats were given melatonin (100 mg/L) with their drinking water throughout the period of pregnancy and lactation (H-MD+M). At 12 weeks of age, male offspring exposed to a L-MD or a H-MD diet developed programmed hypertension. Maternal melatonin therapy attenuated high methyl-donor diet-induced programmed hypertension. A maternal L MD diet and H-MD diet caused respectively 938 and 806 renal transcripts to be modified in adult offspring. The protective effects of melatonin against programmed hypertension relate to reduced oxidative stress, increased urinary NO2 level, and reduced renal expression of sodium transporters. A H-MD or L-MD diet may upset the balance of methylation status, leading to alterations of renal transcriptome and programmed hypertension. A better understanding of reprogramming effects of melatonin might aid in developing a therapeutic strategy for the prevention of hypertension in adult offspring exposed to an excessive maternal methyl-supplemented diet. PMID- 30279342 TI - Inhibition of Tetraspanin Functions Impairs Human Papillomavirus and Cytomegalovirus Infections. AB - Tetraspanins are suggested to regulate the composition of cell membrane components and control intracellular transport, which leaves them vulnerable to utilization by pathogens such as human papillomaviruses (HPV) and cytomegaloviruses (HCMV) to facilitate host cell entry and subsequent infection. In this study, by means of cellular depletion, the cluster of differentiation (CD) tetraspanins CD9, CD63, and CD151 were found to reduce HPV16 infection in HeLa cells by 50 to 80%. Moreover, we tested recombinant proteins or peptides of specific tetraspanin domains on their effect on the most oncogenic HPV type, HPV16, and HCMV. We found that the C-terminal tails of CD63 and CD151 significantly inhibited infections of both HPV16 and HCMV. Although CD9 was newly identified as a key cellular factor for HPV16 infection, the recombinant CD9 C terminal peptide had no effect on infection. Based on the determined half-maximal inhibitory concentration (IC50), we classified CD63 and CD151 C-terminal peptides as moderate to potent inhibitors of HPV16 infection in HeLa and HaCaT cells, and in EA.hy926, HFF (human foreskin fibroblast) cells, and HEC-LTT (human endothelial cell-large T antigen and telomerase) cells for HCMV, respectively. These results indicate that HPV16 and HCMV share similar cellular requirements for their entry into host cells and reveal the necessity of the cytoplasmic CD151 and CD63 C-termini in virus infections. Furthermore, this highlights the suitability of these peptides for functional investigation of tetraspanin domains and as inhibitors of pathogen infections. PMID- 30279344 TI - Preparation and Assessment of Heat-Treated alpha-Chitin Nanowhiskers Reinforced Poly(viny alcohol) Film for Packaging Application. AB - In this study, poly(vinyl alcohol) (PVA) composite films enhanced by alpha-chitin nanowhiskers (ChWs) were prepared through heat treatment. The obtained membranes were assessed by means of FTIR spectroscopy, X-ray diffraction, thermogravimetric analysis, regular light transmittance, mechanical tests, permeability and water absorption. The influence of the nano-component and heat treatment on the mechanical, thermal and water-resistant properties of the composite membrane were analyzed. From the results of the work, the produced films with excellent barrier properties and inexpensive raw processed materials have great prospects in packaging applications. PMID- 30279343 TI - New N-(oxazolylmethyl)-thiazolidinedione Active against Candida albicans Biofilm: Potential Als Proteins Inhibitors. AB - C. albicans is the most frequently occurring fungal pathogen, and is becoming an increasing public health problem, especially in the context of increased microbial resistance. This opportunistic pathogen is characterized by a versatility explained mainly by its ability to form complex biofilm structures that lead to enhanced virulence and antibiotic resistance. In this context, a review of the known C. albicans biofilm formation inhibitors were performed and a new N-(oxazolylmethyl)-thiazolidinedione scaffold was constructed. 16 new compounds were synthesized and characterized in order to confirm their proposed structures. A general antimicrobial screening against Gram-positive and Gram negative bacteria, as well as fungi, was performed and revealed that the compounds do not have direct antimicrobial activity. The anti-biofilm activity evaluation confirmed the compounds act as selective inhibitors of C. albicans biofilm formation. In an effort to substantiate this biologic profile, we used in silico investigations which suggest that the compounds could act by binding, and thus obstructing the functions of, the C. albicans Als surface proteins, especially Als1, Als3, Als5 and Als6. Considering the well documented role of Als1 and Als3 in biofilm formation, our new class of compounds that target these proteins could represent a new approach in C. albicans infection prevention and management. PMID- 30279345 TI - Post-Exercise Appetite and Ad Libitum Energy Intake in Response to High-Intensity Interval Training versus Moderate- or Vigorous-Intensity Continuous Training among Physically Inactive Middle-Aged Adults. AB - High-intensity interval training (HIIT) is considered a time-efficient exercise strategy for weight management. However, data regarding the acute appetite and energy intake responses to HIIT versus continuous training remain inconclusive. This study investigated the ad libitum energy intake and appetite responses to a single session of HIIT versus moderate-intensity continuous training (MICT) and vigorous-intensity continuous training (VICT). Using a randomized crossover design, 11 middle-aged physically inactive men (45.7 +/- 7.4 years, 23.5 +/- 2.1 kg m-2) participated in three treadmill trials at 7-day intervals. HIIT comprised 10 1-min periods at 100% VO2max interspersed with 1-min periods of active recovery. MICT comprised a 40-min session at 65% VO2max, while VICT comprised a 20-min session at 80% VO2max. After each trial, the participants consumed an ad libitum buffet meal for which the energy intake was recorded. The participants' perceived appetite was assessed before and after exercise sessions using the Visual Analogue Scale (VAS). No significant differences in post-exercise ad libitum energy intake were observed between trials (HIIT: 645 +/- 262.9 kcal; MICT: 614.7 +/- 271.2 kcal; VICT: 623.1 +/- 249.0 kcal, p > 0.05). Although the perceived appetite responses exhibited a significant main effect of time (p < 0.01), no group differences were observed (p > 0.05). In summary, these findings suggest that the interval or continuous nature of exercise has no significant effect on appetite responses in physically inactive middle-aged adults, at least during the short-term post-exercise period. PMID- 30279346 TI - Comparative Genomics among Closely Related Streptomyces Strains Revealed Specialized Metabolite Biosynthetic Gene Cluster Diversity. AB - Specialized metabolites are of great interest due to their possible industrial and clinical applications. The increasing number of antimicrobial resistant infectious agents is a major health threat and therefore, the discovery of chemical diversity and new antimicrobials is crucial. Extensive genomic data from Streptomyces spp. confirm their production potential and great importance. Genome sequencing of the same species strains indicates that specialized metabolite biosynthetic gene cluster (SMBGC) diversity is not exhausted, and instead, a pool of novel specialized metabolites still exists. Here, we analyze the genome sequence data from six phylogenetically close Streptomyces strains. The results reveal that the closer strains are phylogenetically, the number of shared gene clusters is higher. Eight specialized metabolites comprise the core metabolome, although some strains have only six core gene clusters. The number of conserved gene clusters common between the isolated strains and their closest phylogenetic counterparts varies from nine to 23 SMBGCs. However, the analysis of these phylogenetic relationships is not affected by the acquisition of gene clusters, probably by horizontal gene transfer events, as each strain also harbors strain specific SMBGCs. Between one and 15 strain-specific gene clusters were identified, of which up to six gene clusters in a single strain are unknown and have no identifiable orthologs in other species, attesting to the existing SMBGC novelty at the strain level. PMID- 30279349 TI - Cadmium-Free Quantum Dots as Fluorescent Labels for Exosomes. AB - Quantum dots are attractive alternatives to organic fluorophores for the purposes of fluorescent labeling and the detection of biomarkers. They can also be made to specifically target a protein of interest by conjugating biomolecules, such as antibodies. However, the majority of the fluorescent labeling using quantum dots is done using toxic materials such as cadmium or lead due to the well-established synthetic processes for these quantum dots. Here, we demonstrate the use of indium phosphide quantum dots with a zinc sulfide shell for the purposes of labeling and the detection of exosomes derived from the THP-1 cell line (monocyte cell line). Exosomes are nano-sized vesicles that have the potential to be used as biomarkers due to their involvement in complex cell processes. However, the lack of standardized methodology around the detection and analysis of exosomes has made it difficult to detect these membrane-containing vesicles. We targeted a protein that is known to exist on the surface of the exosomes (CD63) using a CD63 antibody. The antibody was conjugated to the quantum dots that were first made water-soluble using a ligand-exchange method. The conjugation was done using carbodiimide coupling, and was confirmed using a range of different methods such as dynamic light scattering, surface plasmon resonance, fluorescent microscopy, and Fourier transform infrared spectroscopy. The conjugation of the quantum dot antibody to the exosomes was further confirmed using similar methods. This demonstrates the potential for the use of a non-toxic conjugate to target nano sized biomarkers that could be further used for the detection of different diseases. PMID- 30279348 TI - Hospital-Acquired Hyponatremia in Children Following Hypotonic versus Isotonic Intravenous Fluids Infusion. AB - Hypotonic solutions have been used in pediatrics for maintenance of intravenous (IV) hydration. However, recent randomized control trials and cohort studies have raised significant concerns for association with hospital-acquired hyponatremia (HAH). The study aimed to assess whether the use of hypotonic parenteral solutions (PS) compared with isotonic PS is associated with increased HAH risk in children with common pediatric conditions. Retrospective chart review of 472 patients aged 2 months to 18 years who received either isotonic or hypotonic PS as maintenance fluids. Administration of hypotonic PS was associated with a four fold increase in risk of developing HAH in the univariate analysis, (unadjusted odds ratio (OR) = 3.99; 95% confidence interval (CI): 1.36-11.69, p = 0.01). Hypotonic PS were associated with HAH (p = 0.04) when adjusted for the level of admission serum CO2. There was a mean decrease of serum sodium of 0.53 mEq/L in the hypotonic group compared to the mean increase of 4.88 mEq/L in the isotonic group. These data suggest that hypotonic PS are associated with HAH in children admitted for common pediatric conditions. Isotonic PS should be considered as a safer choice for maintenance fluid hydration. PMID- 30279350 TI - Hand Laser Perfusion Imaging to Assess Radial Artery Patency: A Pilot Study. AB - OBJECTIVES: To test a novel diagnostic technique to assess radial artery perfusion after transradial catheterization. BACKGROUND: Despite being mostly asymptomatic, radial artery occlusion (RAO) is not a benign complication, and its diagnosis is frequently missed because it requires time-consuming diagnostic testing. We developed a novel operator-independent diagnostic test to assess RAO after coronary procedures through a transradial access (TRA) by means of hand Laser Perfusion Imaging (LPI). METHODS: One hundred patients were evaluated before and after TRA by means of the LPI. A radial perfusion index (RPI) was calculated as the ratio between the total perfusion measured during ulnar occlusion and total basal perfusion. Vascular Duplex scan (VDS) was used as the standard of reference to assess the artery patency. RESULTS: LPI correctly identified RAO in 100% of cases. Post-procedural RPI was 0.89 +/- 0.13 in patients with radial patency vs. 0.15 +/- 0.04 in patients with RAO (p < 0.001). In line with these results, ROC analysis showed an excellent diagnostic performance of the LPI, that correctly identified all RAO cases (Area Under the Curve, AUC = 1.0; p < 0.001), with an optimal diagnostic cutoff at 0.2 RPI. CONCLUSIONS: LPI is a reliable diagnostic technique for RAO, offering the advantages of being quick and simple to perform. PMID- 30279351 TI - Structural Optimization of Foldamer-Dendrimer Conjugates as Multivalent Agents against the Toxic Effects of Amyloid Beta Oligomers. AB - Alzheimer's disease is one of the most common chronic neurodegenerative disorders. Despite several in vivo and clinical studies, the cause of the disease is poorly understood. Currently, amyloid beta (Abeta) peptide and its tendency to assemble into soluble oligomers are known as a main pathogenic event leading to the interruption of synapses and brain degeneration. Targeting neurotoxic Abeta oligomers can help recognize the disease at an early stage or it can be a potential therapeutic approach. Unnatural beta-peptidic foldamers are successfully used against many different protein targets due to their favorable structural and pharmacokinetic properties compared to small molecule or protein like drug candidates. We have previously reported a tetravalent foldamer dendrimer conjugate which can selectively bind Abeta oligomers. Taking advantage of multivalency and foldamers, we synthesized different multivalent foldamer based conjugates to optimize the geometry of the ligand. Isothermal titration calorimetry (ITC) was used to measure binding affinity to Abeta, thereafter 3 (4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) based tissue viability assay and impedance-based viability assay on SH-SY5Y cells were applied to monitor Abeta toxicity and protective effects of the compounds. Important factors for high binding affinity were determined and a good correlation was found between influencing the valence and the capability of the conjugates for Abeta binding. PMID- 30279347 TI - Oncogenic Signaling Induced by HCV Infection. AB - The liver is frequently exposed to toxins, metabolites, and oxidative stress, which can challenge organ function and genomic stability. Liver regeneration is therefore a highly regulated process involving several sequential signaling events. It is thus not surprising that individual oncogenic mutations in hepatocytes do not necessarily lead to cancer and that the genetic profiles of hepatocellular carcinomas (HCCs) are highly heterogeneous. Long-term infection with hepatitis C virus (HCV) creates an oncogenic environment by a combination of viral protein expression, persistent liver inflammation, oxidative stress, and chronically deregulated signaling events that cumulate as a tipping point for genetic stability. Although novel direct-acting antivirals (DAA)-based treatments efficiently eradicate HCV, the associated HCC risk cannot be fully eliminated by viral cure in patients with advanced liver disease. This suggests that HCV may persistently deregulate signaling pathways beyond viral cure and thereby continue to perturb cancer-relevant gene function. In this review, we summarize the current knowledge about oncogenic signaling pathways derailed by chronic HCV infection. This will not only help to understand the mechanisms of hepatocarcinogenesis but will also highlight potential chemopreventive strategies to help patients with a high-risk profile of developing HCC. PMID- 30279353 TI - Resistance of Superhydrophobic Surface-Functionalized TiO2 Nanotubes to Corrosion and Intense Cavitation. AB - The availability of robust superhydrophobic materials with the ability to withstand harsh environments are in high demand for many applications. In this study, we have presented a simple method to fabricate superhydrophobic materials from TiO2 nanotube arrays (TNTAs) and investigated the resilience of the materials when they are subjected to harsh conditions such as intense cavitation upon ultrasonication, corrosion in saline water, water-jet impact, and abrasion. The TNTAs were prepared by anodization of Ti foil in buffered aqueous electrolyte containing fluoride ions. The hydrophilic TNTAs were functionalized with octadecylphosphonic acid (ODPA) or 1H, 1H', 2H, 2H'-perfluorodecyl phosphonic acid (PFDPA) to form a self-assembled monolayer on the TNTA surface to produce superhydrophobic ODPA@TNTA or PFDPA@TNTA surfaces. The superhydrophobic ODPA@TNTA and PFDPA@TNTA have contact angles of 156.0 degrees +/- 1.5 degrees and 168 degrees +/- 1.5 degrees , and contact angle hysteresis of 3.0 degrees and 0.8 degrees , respectively. The superhydrophobic ODPA@TNTA and PFDPA@TNTA were subjected to ultrasonication, corrosion in saline water, and water-jet impact and abrasion, and the resilience of the systems was characterized by electrochemical impedance spectroscopy (EIS), contact angle (CA) measurements, diffuse reflectance Fourier transform infrared spectroscopy (DRIFTS), and field-emission scanning electron microscopy (FESEM). The results presented here show that superhydrophobic ODPA@TNTA and PFDPA@TNTA are robust and resilient under the harsh conditions studied in this work, and indicate the potential of these materials to be deployed in practical applications. PMID- 30279355 TI - Impact of Genomics on Clarifying the Evolutionary Relationships amongst Mycobacteria: Identification of Molecular Signatures Specific for the Tuberculosis-Complex of Bacteria with Potential Applications for Novel Diagnostics and Therapeutics. AB - An alarming increase in tuberculosis (TB) caused by drug-resistant strains of Mycobacterium tuberculosis has created an urgent need for new antituberculosis drugs acting via novel mechanisms. Phylogenomic and comparative genomic analyses reviewed here reveal that the TB causing bacteria comprise a small group of organisms differing from all other mycobacteria in numerous regards. Comprehensive analyses of protein sequences from mycobacterial genomes have identified 63 conserved signature inserts and deletions (indels) (CSIs) in important proteins that are distinctive characteristics of the TB-complex of bacteria. The identified CSIs provide potential means for development of novel diagnostics as well as therapeutics for the TB-complex of bacteria based on four key observations: (i) The CSIs exhibit a high degree of exclusivity towards the TB-complex of bacteria; (ii) Earlier work on CSIs provide evidence that they play important/essential functions in the organisms for which they exhibit specificity; (iii) CSIs are located in surface-exposed loops of the proteins implicated in mediating novel interactions; (iv) Homologs of the CSIs containing proteins, or the CSIs in such homologs, are generally not found in humans. Based on these characteristics, it is hypothesized that the high-throughput virtual screening for compounds binding specifically to the CSIs (or CSI containing regions) and thereby inhibiting the cellular functions of the CSIs could lead to the discovery of a novel class of drugs specifically targeting the TB-complex of organisms. PMID- 30279352 TI - The Effect of Aspergillus Thermomutatus Chrysovirus 1 on the Biology of Three Aspergillus Species. AB - This study determined the effects of Aspergillus thermomutatus chrysovirus 1 (AthCV1), isolated from Aspergillus thermomutatus, on A. fumigatus, A. nidulans and A. niger. Protoplasts of virus-free isolates of A. fumigatus, A. nidulans and A. niger were transfected with purified AthCV1 particles and the phenotype, growth and sporulation of the isogenic AthCV1-free and AthCV1-infected lines assessed at 20 degrees C and 37 degrees C and gene expression data collected at 37 degrees C. AthCV1-free and AthCV1-infected A. fumigatus produced only conidia at both temperatures but more than ten-fold reduced compared to the AthCV1 infected line. Conidiation was also significantly reduced in infected lines of A. nidulans and A. niger at 37 degrees C. AthCV1-infected lines of A. thermomutatus and A. nidulans produced large numbers of ascospores at both temperatures, whereas the AthCV1-free line of the former did not produce ascospores. AthCV1 infected lines of all species developed sectoring phenotypes with sclerotia produced in aconidial sectors of A. niger at 37 degrees C. AthCV1 was detected in 18% of sclerotia produced by AthCV1-infected A. niger and 31% of ascospores from AthCV1-infected A. nidulans. Transcriptome analysis of the naturally AthCV1 infected A. thermomutatus and the three AthCV1-transfected Aspergillus species showed altered gene expression as a result of AthCV1-infection. The results demonstrate that AthCV1 can infect a range of Aspergillus species resulting in reduced sporulation, a potentially useful attribute for a biological control agent. PMID- 30279354 TI - Effects of Polyacrylic Acid Pre-Treatment on Bonded-Dentine Interfaces Created with a Modern Bioactive Resin-Modified Glass Ionomer Cement and Subjected to Cycling Mechanical Stress. AB - OBJECTIVES: Resin-modified glass ionomer cements (RMGIC) are considered excellent restorative materials with unique therapeutic and anti-cariogenic activity. However, concerns exist regarding the use of polyacrylic acid as a dentine conditioner as it may influence the bonding performance of RMGIC. The aim of this study was to evaluate the effect of different protocols for cycling mechanical stress on the bond durability and interfacial ultramorphology of a modern RMGIC applied to dentine pre-treated with/without polyacrylic acid conditioner (PAA). METHODS: The RMGIC was applied onto human dentine specimens prepared with silicon carbide (SiC) abrasive paper with or without the use of a PAA conditioner. The specimens were immersed in deionised water for 24 h then divided in 3 groups. The first group was cut into matchsticks (cross-sectional area of 0.9 mm2) and tested immediately for microtensile bond strength (MTBS). The second was first subjected to load cycling (250,000 cycles; 3 Hz; 70 N) and then cut into matchsticks and tested for MTBS. The third group was subjected to load cycling (250,000 cycles; 3 Hz; 70 N), cut into matchsticks, and then immersed for 8 months storage in artificial saliva (AS); these were finally tested for MTBS. The results were analysed statistically using two-way ANOVA and the Student-Newman-Keuls test (alpha = 0.05). Fractographic analysis was performed using FE-SEM, while further RMCGIC-bonded dentine specimens were aged as previously described and used for interfacial ultramorphology characterisation (dye nanoleakage) using confocal microscopy. RESULTS: The RMGIC applied onto dentine that received no pre treatment (10% PAA gel) showed no significant reduction in MTBS after load cycling followed by 8 months of storage in AS (p > 0.05). The RMGIC-dentine interface created in PAA-conditioned SiC-abraded dentine specimens showed no sign of degradation, but with porosities within the bonding interface both after load cycling and after 8 months of storage in AS. Conversely, the RMGIC-dentine interface of the specimens with no PAA pre-treatment showed no sign of porosity within the interface after any of the aging protocols, although some bonded dentine interfaces presented cohesive cracks within the cement after prolonged AS storage. However, the specimens of this group showed no significant reduction in bond strength (p < 0.05) after 8 months of storage in AS or load cycling (p > 0.05). After prolonged AS storage, the bond strength value attained in RMGIC dentine specimens created in PAA pre-treated dentine were significantly higher than those observed in the specimens created with no PAA pre-treatment in dentine. CONCLUSIONS: PAA conditioning of dentine prior to application of RMGIC induces no substantial effect on the bond strength after short-term storage, but its use may increase the risk of collagen degradation at the bonding interface after prolonged aging. Modern RMGIC applied without PAA dentine pre-treatment may have greater therapeutic synergy with saliva during cycle occlusal load, thereby enhancing the remineralisation and protection of the bonding interface. PMID- 30279357 TI - Genetic Abnormalities, Clonal Evolution, and Cancer Stem Cells of Brain Tumors. AB - Brain tumors are highly heterogeneous and have been classified by the World Health Organization in various histological and molecular subtypes. Gliomas have been classified as ranging from low-grade astrocytomas and oligodendrogliomas to high-grade astrocytomas or glioblastomas. These tumors are characterized by a peculiar pattern of genetic alterations. Pediatric high-grade gliomas are histologically indistinguishable from adult glioblastomas, but they are considered distinct from adult glioblastomas because they possess a different spectrum of driver mutations (genes encoding histones H3.3 and H3.1). Medulloblastomas, the most frequent pediatric brain tumors, are considered to be of embryonic derivation and are currently subdivided into distinct subgroups depending on histological features and genetic profiling. There is emerging evidence that brain tumors are maintained by a special neural or glial stem cell like population that self-renews and gives rise to differentiated progeny. In many instances, the prognosis of the majority of brain tumors remains negative and there is hope that the new acquisition of information on the molecular and cellular bases of these tumors will be translated in the development of new, more active treatments. PMID- 30279356 TI - Rice Routes of Countering Xanthomonas oryzae. AB - Bacterial blight (BB) and bacterial leaf streak (BLS), caused by Xanthomonas oryzae pv. oryzae and Xanthomonas oryzae pv. oryzicola, respectively, are two devastating diseases in rice planting areas worldwide. It has been proven that adoption of rice resistance is the most effective, economic, and environment friendly strategy to avoid yield loss caused by BB and BLS. As a model system for plant-pathogen interaction, the rice-X. oryzae pathosystem has been intensively investigated in the past decade. Abundant studies have shown that the resistance and susceptibility of rice to X. oryzae is determined by molecular interactions between rice genes or their products and various pathogen effectors. In this review, we briefly overviewed the literature regarding the diverse interactions, focusing on recent advances in uncovering mechanisms of rice resistance and X. oryzae virulence. Our analysis and discussions will not only be helpful for getting a better understanding of coevolution of the rice innate immunity and X. oryzae virulence, but it will also provide new insights for application of plant R genes in crop breeding. PMID- 30279359 TI - Antimicrobial and Antibiofilm Activity of a Recombinant Fragment of beta-Thymosin of Sea Urchin Paracentrotus lividus. AB - With the aim to obtain new antimicrobials against important pathogens such as Staphylococcus aureus and Pseudomonas aeruginosa, we focused on antimicrobial peptides (AMPs) from Echinoderms. An example of such peptides is Paracentrin 1 (SP1), a chemically synthesised peptide fragment of a sea urchin thymosin. In the present paper, we report on the biological activity of a Paracentrin 1 derivative obtained by recombination. The recombinant paracentrin RP1, in comparison to the synthetic SP1, is 22 amino acids longer and it was considerably more active against the planktonic forms of S. aureus ATCC 25923 and P. aeruginosa ATCC 15442 at concentrations of 50 ug/mL. Moreover, it was able to inhibit biofilm formation of staphylococcal and P. aeruginosa strains at concentrations equal to 5.0 and 10.7 ug/mL, respectively. Molecular dynamics (MD) simulations allowed to rationalise the results of the experimental investigations, providing atomistic insights on the binding of RP1 toward models of mammalian and bacterial cell membranes. Overall, the results obtained point out that RP1 shows a remarkable preference for bacterial membranes, in excellent agreement with the antibacterial activity, highlighting the promising potential of using the tested peptide as a template for the development of novel antimicrobial agents. PMID- 30279358 TI - A Systematic Review of Access to Rehabilitation for People with Disabilities in Low- and Middle-Income Countries. AB - Rehabilitation seeks to optimize functioning of people with impairments and includes a range of specific health services-diagnosis, treatment, surgery, assistive devices, and therapy. Evidence on access to rehabilitation services for people with disabilities in low- and middle-income countries (LMICs) is limited. A systematic review was conducted to examine this in depth. In February 2017, six databases were searched for studies measuring access to rehabilitation among people with disabilities in LMICs. Eligible measures of access to rehabilitation included: use of assistive devices, use of specialist health services, and adherence to treatment. Two reviewers independently screened titles, abstracts, and full texts. Data was extracted by one reviewer and checked by a second. Of 13,048 screened studies, 77 were eligible for inclusion. These covered a broad geographic area. 17% of studies measured access to hearing-specific services; 22% vision-specific; 31% physical impairment-specific; and 44% measured access to mental impairment-specific services. A further 35% measured access to services for any disability. A diverse range of measures of disability and access were used across studies making comparability difficult. However, there was some evidence that access to rehabilitation is low among people with disabilities. No clear patterns were seen in access by equity measures such as age, locality, socioeconomic status, or country income group due to the limited number of studies measuring these indicators, and the range of measures used. Access to rehabilitation services was highly variable and poorly measured within the studies in the review, but generally shown to be low. Far better metrics are needed, including through clinical assessment, before we have a true appreciation of the population level need for and coverage of these services. PMID- 30279361 TI - Effects of 1-Methyltryptophan on Immune Responses and the Kynurenine Pathway after Lipopolysaccharide Challenge in Pigs. AB - An enhanced indoleamine 2,3-dioxygenase 1 (IDO1) activity is associated with an increased mortality risk in sepsis patients. Thus, the preventive inhibition of IDO1 activity may be a promising strategy to attenuate the severity of septic shock. 1-methyltryptophan (1-MT) is currently in the interest of research due to its potential inhibitory effects on IDO1 and immunomodulatory properties. The present study aims to investigate the protective and immunomodulatory effects of 1-methyltryptophan against endotoxin-induced shock in a porcine in vivo model. Effects of 1-MT were determined on lipopolysaccharide (LPS)-induced tryptophan (TRP) degradation, immune response and sickness behaviour. 1-MT increased TRP and its metabolite kynurenic acid (KYNA) in plasma and tissues, suppressed the LPS induced maturation of neutrophils and increased inactivity of the animals. 1-MT did not inhibit the LPS-induced degradation of TRP to kynurenine (KYN)-a marker for IDO1 activity-although the increase in KYNA indicates that degradation to one branch of the KYN pathway is facilitated. In conclusion, our findings provide no evidence for IDO1 inhibition but reveal the side effects of 1-MT that may result from the proven interference of KYNA and 1-MT with aryl hydrocarbon receptor signalling. These effects should be considered for therapeutic applications of 1 MT. PMID- 30279360 TI - Towards a Food-Based Intervention to Increase Protein Intakes in Older Adults: Challenges to and Facilitators of Egg Consumption. AB - : Abstract: Background: Dietary protein intake is important for health. Eggs, as a protein-rich food with characteristics that appeal to older adults, may provide opportunities for increasing protein intake. Interventions that focus on the challenges or facilitators that affect a large proportion of the population will be of increased impact on a population-wide scale. This work aimed to investigate the relative importance of a number of challenges to and facilitators of egg consumption in a UK population-wide sample of older adults. METHODS: A cross sectional postal questionnaire, measuring habitual egg intake, reasons for eating/not eating eggs and a range of demographic and lifestyle characteristics, was administered by post to 1082 older adults. RESULTS: 230 questionnaires suitable for analysis were returned (110 females, ages 55-80+ years). Habitual egg intake ranged from 1-89 eggs/month, mean (standard deviation) = 18 (13) eggs/month. Reasons for eating/not eating eggs were reduced using Principal Components Analysis to 23 challenges and facilitators of egg consumption. Regression analyses revealed habitual egg intake to be associated with 10 challenges and facilitators (smallest beta = 0.14, p = 0.04), and with protein consumption, age and Body Mass Index (smallest beta = 0.14, p = 0.03). DISCUSSION: Many possibilities for future intervention based on existing challenges or facilitators were found. Our results suggest that strategies to increase egg consumption in older adults should focus on: improving liking, tastiness and adding variety; promoting eggs as an everyday type of food; reducing stereotypes about who does and who does not consume eggs; and promoting eggs for people who have noticed the effects of ageing on their food intake. Strategies that highlight value-for-money may be counterproductive. Future work evaluating the value of these strategies for improving protein intake in this age group would be of value.

AB - A primary lead smelter operated in Santo Amaro City in Brazil from 1960 to 1993, leaving approximately 500,000 tons of industrial dross containing 2-3% of lead and other toxic elements that contaminated the industry grounds and the urban environment. This study aimed to present the local residents' perception towards soil contamination by the smelter. In a cross-sectional study, 208 residents from randomly selected households were interviewed about dross hazards and proposals for its management. A city map depicts the distribution and concentration of lead, cadmium, arsenic, zinc, nickel, and antimony, measured in the soil of the 39 households with visible smelter dross. Only one site complies with the soil quality reference values; 27 (69.2%) call for preventive measures, and 11 (28.2%) require intervention. The smelter dross continues widely spread over the city. Thirty (76.9%) out of the 39 residents were able to recognize the smelter dross on household surroundings. However, this ability was not associated with the concentrations of toxic elements in the soil of their residences and surroundings. The smelter and the local Prefecture were most frequently held liable for taking soil cleanup actions. The most frequently (38.0%) cited solution for managing the dross found in the households was "to provide the residents with information about health risks related to the dross".

AB - Recipes have a great impact on consumers' behavior in the kitchen; building a recipe requires the understanding of the potential user. The objective of this study was to develop and evaluate different recipe styles for the preparation of doughs by understanding people's descriptions of these. Two qualitative studies were performed (43 wheat and 50 corn dough preparers). During interviews, participants described the preparation process of the doughs using the Think Aloud technique. Finished doughs were described as not sticky, soft, and pliable. Based on these descriptions, five recipes were created: not detailed, detailed, very detailed, paragraph-form, and 'with images'. Recipes were validated in two online surveys (total n = 600), where respondents evaluated the easiness, likeability, likelihood of using, helpfulness, and amount of information. Respondents considered the recipe with images as easier and more helpful. The very detailed recipe was considered more difficult, less helpful, and was liked less than the other recipes. Understanding and identifying the terms and techniques people use is a good way to communicate how to prepare a food product and can be used to develop and improve recipes. However, the format in which the recipe is presented is an important factor considered by users when following recipes. PMID- 30279363 TI - Gap Junction Intercellular Communication Positively Regulates Cisplatin Toxicity by Inducing DNA Damage through Bystander Signaling. AB - The radiation-induced bystander effect (RIBE) can increase cellular toxicity in a gap junction dependent manner in unirradiated bystander cells. Recent reports have suggested that cisplatin toxicity can also be mediated by functional gap junction intercellular communication (GJIC). In this study using lung and ovarian cancer cell lines, we showed that cisplatin cytotoxicity is mediated by cellular density. This effect is ablated when GJA1 or Connexin 43 (Cx43) is targeted, a gap junction gene and protein, respectively, leading to cisplatin resistance but only at high or gap junction forming density. We also observed that the cisplatin mediated bystander effect was elicited as DNA Double Strand Breaks (DSBs) with positive H2AX Ser139 phosphorylation (gammaH2AX) formation, an indicator of DNA DSBs. These DSBs are not observed when gap junction formation is prevented. We next showed that cisplatin is not the "death" signal traversing the gap junctions by utilizing the cisplatin-GG intrastrand adduct specific antibody. Finally, we also showed that cells deficient in the structure-specific DNA endonuclease ERCC1 ERCC4 (ERCC1-XPF), an important mediator of cisplatin resistance, further sensitized when treated with cisplatin in the presence of gap junction forming density. Taken together, these results demonstrate the positive effect of GJIC on increasing cisplatin cytotoxicity.

AB - Ceramides, abundant sphingolipids on the cell membrane, can act as signaling molecules to regulate cellular functions including cell viability. Exogenous ceramide has been shown to exert potent anti-proliferative effects against cancer cells, but little is known about how it affects reactive oxygen species (ROS) in lung cancer cells. In this study, we investigated the effect of N-octanoyl-D erythro-sphingosine (C8-ceramide) on human non-small-cell lung cancer H1299 cells. Flow cytometry-based assays indicated that C8-ceramide increased the level of endogenous ROS in H1299 cells. Interestingly, the ratio of superoxide dismutases (SODs) SOD1 and SOD2 seem to be regulated by C8-ceramide treatment. Furthermore, the accumulation of cell cycle G1 phase and apoptotic populations in C8-ceramide-treated H1299 cells was observed. The results of the Western blot showed that C8-ceramide causes a dramatically increased protein level of cyclin D1, a critical regulator of cell cycle G1/S transition. These results suggest that C8-ceramide acts as a potent chemotherapeutic agent and may increase the endogenous ROS level by regulating the switch of SOD1 and SOD2, causing the anti proliferation, and consequently triggering the apoptosis of NSCLC H1299 cells. Accordingly, our works may give a promising strategy for lung cancer treatment in the future. PMID- 30279367 TI - Interference of Biodegradable Plastics in the Polypropylene Recycling Process. AB - Recycling polymers is common due to the need to reduce the environmental impact of these materials. Polypropylene (PP) is one of the polymers called 'commodities polymers' and it is commonly used in a wide variety of short-term applications such as food packaging and agricultural products. That is why a large amount of PP residues that can be recycled are generated every year. However, the current increasing introduction of biodegradable polymers in the food packaging industry can negatively affect the properties of recycled PP if those kinds of plastics are disposed with traditional plastics. For this reason, the influence that generates small amounts of biodegradable polymers such as polylactic acid (PLA), polyhydroxybutyrate (PHB) and thermoplastic starch (TPS) in the recycled PP were analyzed in this work. Thus, recycled PP was blended with biodegradables polymers by melt extrusion followed by injection moulding process to simulate the industrial conditions. Then, the obtained materials were evaluated by studding the changes on the thermal and mechanical performance. The results revealed that the vicat softening temperature is negatively affected by the presence of biodegradable polymers in recycled PP. Meanwhile, the melt flow index was negatively affected for PLA and PHB added blends. The mechanical properties were affected when more than 5 wt.% of biodegradable polymers were present. Moreover, structural changes were detected when biodegradable polymers were added to the recycled PP by means of FTIR, because of the characteristic bands of the carbonyl group (between the band 1700-1800 cm-1) appeared due to the presence of PLA, PHB or TPS. Thus, low amounts (lower than 5 wt.%) of biodegradable polymers can be introduced in the recycled PP process without affecting the overall performance of the final material intended for several applications, such as food packaging, agricultural films for farming and crop protection. PMID- 30279366 TI - 2D Material Science: Defect Engineering by Particle Irradiation. AB - Two-dimensional (2D) materials are at the heart of many novel devices due to their unique and often superior properties. For simplicity, 2D materials are often assumed to exist in their text-book form, i.e., as an ideal solid with no imperfections. However, defects are ubiquitous in macroscopic samples and play an important - if not imperative - role for the performance of any device. Thus, many independent studies have targeted the artificial introduction of defects into 2D materials by particle irradiation. In our view it would be beneficial to develop general defect engineering strategies for 2D materials based on a thorough understanding of the defect creation mechanisms, which may significantly vary from the ones relevant for 3D materials. This paper reviews the state-of-the art in defect engineering of 2D materials by electron and ion irradiation with a clear focus on defect creation on the atomic scale and by individual impacts. Whenever possible we compile reported experimental data alongside corresponding theoretical studies. We show that, on the one hand, defect engineering by particle irradiation covers a wide range of defect types that can be fabricated with great precision in the most commonly investigated 2D materials. On the other hand, gaining a complete understanding still remains a challenge, that can be met by combining advanced theoretical methods and improved experimental set-ups, both of which only now begin to emerge. In conjunction with novel 2D materials, this challenge promises attractive future opportunities for researchers in this field. PMID- 30279368 TI - Establishing the Phenolic Composition of Olea europaea L. Leaves from Cultivars Grown in Morocco as a Crucial Step Towards Their Subsequent Exploitation. AB - In Morocco, the recovery of olive agro-industrial by-products as potential sources of high-added value substances has been underestimated so far. A comprehensive quantitative characterization of olive leaves' bioactive compounds is crucial for any attempt to change this situation and to implement the valorization concept in emerging countries. Thus, the phenolic fraction of olive leaves of 11 varieties ('Arbequina', 'Hojiblanca', 'Frantoio', 'Koroneiki', 'Lechin', 'Lucque', 'Manzanilla', 'Picholine de Languedoc', 'Picholine Marocaine', 'Picual' and 'Verdal'), cultivated in the Moroccan Meknes region, was investigated. Thirty eight phenolic or related compounds (including 16 secoiridoids, nine flavonoids in their aglycone form, seven flavonoids in glycosylated form, four simple phenols, one phenolic acid and one lignan) were determined in a total of 55 samples by using ultrasonic-assisted extraction and liquid chromatography coupled to electrospray ionization-ion trap mass spectrometry (LC-ESI-IT MS). Very remarkable quantitative differences were observed among the profiles of the studied cultivars. 'Picholine Marocaine' variety exhibited the highest total phenolic content (around 44 g/kg dry weight (DW)), and logically showed the highest concentration in terms of various individual compounds. In addition, chemometrics (principal components analysis (PCA) and stepwise-linear discriminant analysis (s-LDA)) were applied to the quantitative phenolic compound data, allowing good discrimination of the selected samples according to their varietal origin. PMID- 30279369 TI - A Population-Based Approach to Mapping Vulnerability to Diabetes. AB - Of the 382 million people worldwide with diabetes, and if current trends continue, nearly half a billion people worldwide will have diabetes by 2035. Two thirds of current diabetics are living in urban centers and the urban concentration of individuals with diabetes is on the rise. The problem is that in the absence of widespread clinical testing, there is no reliable way to predict which segments of the population are the most vulnerable to the onset of diabetes. Knowing who the most vulnerable are, and where they live, can guide the efficient allocation of prevention resources. Toward this end, we introduce the concept of composite vulnerability, which includes both group and individual level attributes, and we provide a demonstration of its application to a large urban setting. The components of composite vulnerability are estimated using a novel, population-based, procedure that relies on sample survey data and nonparametric statistical techniques. First, cluster analysis identified three multivariate profiles of adult residents with type 2 diabetes, based on 35 socioeconomic indicators. Second, the undiagnosed population was screened for vulnerability based on their resemblance or fit to these multivariate profiles. Geographic neighborhoods with high concentrations of "vulnerables" could then be identified. In parallel, recursive partitioning found the best predictors of type 2 diabetes in this urban population, combined them with indicators of disadvantage, and applied them to residents in the selected neighborhoods to establish relative levels of composite vulnerability. Neighborhoods with high concentrations of residents manifesting composite vulnerability can be easily identified for targeting community-based prevention measures. PMID- 30279370 TI - A Hybrid Textile Electrode for Electrocardiogram (ECG) Measurement and Motion Tracking. AB - Wearable sensors have great potential uses in personal health monitoring systems, in which textile-based electrodes are particularly useful because they are comfortable to wear and are skin and environmentally friendly. In this paper, a hybrid textile electrode for electrocardiogram (ECG) measurement and motion tracking was introduced. The hybrid textile electrode consists of two parts: A textile electrode for ECG monitoring, and a motion sensor for patient activity tracking. In designing the textile electrodes, their performance in ECG measurement was investigated. Two main influencing factors on the skin-electrode impedance of the electrodes were found: Textile material properties, and electrode sizes. The optimum textile electrode was silver plated, made of a high stitch density weft knitted conductive fabric and its size was 20 mm * 40 mm. A flexible motion sensor circuit was designed and integrated within the textile electrode. Systematic measurements were performed, and results have shown that the hybrid textile electrode is capable of recording ECG and motion signals synchronously, and is suitable for ambulatory ECG measurement and motion tracking applications. PMID- 30279371 TI - Effect of Oxygen Partial Pressure on the Phase Stability of Copper-Iron Delafossites at Elevated Temperatures. AB - Oxide-based materials are promising candidates for use in high temperature thermoelectric generators. While their thermoelectric performance is inferior to commonly used thermoelectrics, oxides are environmentally friendly and cost effective. In this study, Cu-based delafossites (CuFeO2), a material class with promising thermoelectric properties at high temperatures, were investigated. This work focuses on the phase stability of CuFeO2 with respect to the temperature and the oxygen partial pressure. For this reason, classical material characterization methods, such as scanning electron microscopy, energy dispersive X-ray spectroscopy, and X-ray diffraction, were combined in order to elucidate the phase composition of delafossites at 900 degrees C at various oxygen partial pressures. The experimentally obtained results are supported by the theoretical calculation of the Ellingham diagram of the copper-oxygen system. In addition, hot-stage X-ray diffraction and long-term annealing tests of CuFeO2 were performed in order to obtain a holistic review of the phase stability of delafossites at high temperatures and varying oxygen partial pressure. The results support the thermoelectric measurements in previous publications and provide a process window for the use of CuFeO2 in thermoelectric generators. PMID- 30279372 TI - Assay Challenges for Emerging Infectious Diseases: The Zika Experience. AB - From the perspective of vaccine development, it is imperative to accurately diagnose target infections in order to exclude subjects with prior exposure from evaluations of vaccine effectiveness, to track incident infection during the course of a clinical trial and to differentiate immune reactions due to natural infections from responses that are vaccine related. When vaccine development is accelerated to a rapid pace in response to emerging infectious disease threats, the challenges to develop such diagnostic tools is even greater. This was observed through the recent expansion of Zika virus infections into the Western Hemisphere in 2014-2017. When initial Zika vaccine clinical trials were being designed and launched in response to the outbreak, there were no standardized sets of viral and immunological assays, and no approved diagnostic tests for Zika virus infection. The diagnosis of Zika virus infection is still an area of active research and development on many fronts. Here we review emerging infectious disease vaccine clinical assay development and trial execution with a special focus on the state of Zika virus clinical assays and diagnostics. PMID- 30279373 TI - Many-Objective Automated Optimization of a Four-Band Antenna for Multiband Wireless Sensor Networks. AB - This paper describes a new design and an optimization framework for a four-band antenna to be used in wireless sensor networks. The antenna is designed to operate effectively in two open frequency bands (ISM-Industrial, Scientific, Medical), 2.4 GHz and 5.8 GHz, as well as in two bands allocated for the fifth generation (5G) cellular networks, 0.7 GHz and 3.5 GHz. Our initial design was developed using the trial and error approach, modifying a circular disc monopole antenna widely used in ultra wideband (UWB) systems. This initial design covered the three upper bands, but impedance matching within the 700 MHz band was unsatisfactory. The antenna performance was then improved significantly using an optimization algorithm that applies a bi-objective fully-Paretian approach to its nine-parameter geometry. The optimization criteria were impedance matching and radiation efficiency. The final design exhibits good impedance matching in all four desired bands with the Voltage Standing Wave Ratio (VSWR) value below 2 and radiation efficiency of 88%. The simulated antenna performance was verified experimentally. PMID- 30279374 TI - Towards an Automated Unsupervised Mobility Assessment for Older People Based on Inertial TUG Measurements. AB - One of the most common assessments for the mobility of older people is the Timed Up and Go test (TUG). Due to its sensitivity regarding the indication of Parkinson's disease (PD) or increased fall risk in elderly people, this assessment test becomes increasingly relevant, should be automated and should become applicable for unsupervised self-assessments to enable regular examinations of the functional status. With Inertial Measurement Units (IMU) being well suited for automated analyses, we evaluate an IMU-based analysis system, which automatically detects the TUG execution via machine learning and calculates the test duration. as well as the duration of its single components. The complete TUG was classified with an accuracy of 96% via a rule-based model in a study with 157 participants aged over 70 years. A comparison between the TUG durations determined by IMU and criterion standard measurements (stopwatch and automated/ambient TUG (aTUG) system) showed significant correlations of 0.97 and 0.99, respectively. The classification of the instrumented TUG (iTUG)-components achieved accuracies over 96%, as well. Additionally, the system's suitability for self-assessments was investigated within a semi-unsupervised situation where a similar movement sequence to the TUG was executed. This preliminary analysis confirmed that the self-selected speed correlates moderately with the speed in the test situation, but differed significantly from each other. PMID- 30279376 TI - Wide-Angle, Ultra-Wideband ISAR Imaging of Vehicles and Drones. AB - In-situ, wide-angle, and ultra-wideband inverse synthetic aperture radar (ISAR) imaging of vehicles and drones is demonstrated using a portable ultra-wideband radar. In order to form well-focused ISAR images, motion compensation is performed before applying the k-space imaging algorithm. While the same basic motion compensation methodology is applied to both types of targets, a more complex motion model is needed to better capture the flight path of the drone. The resulting ISAR images clearly show the geometrical outline of the targets and highlight locations of prominent backscattering. The ISAR images are also assessed against images generated through instrumented targets or laboratory measurements, and the image quality is shown to be comparable. PMID- 30279375 TI - Genome-Wide Association Study Reveals Novel Genomic Regions for Grain Yield and Yield-Related Traits in Drought-Stressed Synthetic Hexaploid Wheat. AB - Synthetic hexaploid wheat (SHW; 2n = 6x = 42, AABBDD, Triticum aestivum L.) is produced from an interspecific cross between durum wheat (2n = 4x = 28, AABB, T. turgidum L.) and goat grass (2n = 2x = 14, DD, Aegilops tauschii Coss.) and is reported to have significant novel alleles-controlling biotic and abiotic stresses resistance. A genome-wide association study (GWAS) was conducted to unravel these loci [marker-trait associations (MTAs)] using 35,648 genotyping-by sequencing-derived single nucleotide polymorphisms in 123 SHWs. We identified 90 novel MTAs (45, 11, and 34 on the A, B, and D genomes, respectively) and haplotype blocks associated with grain yield and yield-related traits including root traits under drought stress. The phenotypic variance explained by the MTAs ranged from 1.1% to 32.3%. Most of the MTAs (120 out of 194) identified were found in genes, and of these 45 MTAs were in genes annotated as having a potential role in drought stress. This result provides further evidence for the reliability of MTAs identified. The large number of MTAs (53) identified especially on the D-genome demonstrate the potential of SHWs for elucidating the genetic architecture of complex traits and provide an opportunity for further improvement of wheat under rapidly changing climatic conditions. PMID- 30279377 TI - Early Responses to Severe Drought Stress in the Arabidopsis thaliana Cell Suspension Culture Proteome. AB - Abiotic stresses are considered the most deleterious factor affecting growth and development of plants worldwide. Such stresses are largely unavoidable and trigger adaptive responses affecting different cellular processes and target different compartments. Shotgun proteomic and mass spectrometry-based approaches offer an opportunity to elucidate the response of the proteome to abiotic stresses. In this study, the severe drought or water-deficit response in Arabidopsis thaliana was mimicked by treating cell suspension callus with 40% polyethylene glycol for 10 and 30 min. Resulting data demonstrated that 310 proteins were differentially expressed in response to this treatment with a strict +/-2.0-fold change. Over-representation was observed in the gene ontology categories of 'ribosome' and its related functions as well as 'oxidative phosphorylation', indicating both structural and functional drought responses at the cellular level. Proteins in the category 'endocytosis' also show significant enrichment and this is consistent with increased active transport and recycling of membrane proteins in response to abiotic stress. This is supported by the particularly pronounced enrichment in proteins of the endosomal sorting complexes that are required for membrane remodelling. Taken together, the findings point to rapid and complex physiological and structural changes essential for survival in response to sudden severe drought stress. PMID- 30279378 TI - Coencapsulation of Polyphenols and Anthocyanins from Blueberry Pomace by Double Emulsion Stabilized by Whey Proteins: Effect of Homogenization Parameters. AB - Blueberry pomace is a rich source of high-value bioactive polyphenols with presumed health benefits. Their incorporation into functional foods and health related products benefits from coencapsulation and protection of polyphenol-rich extracts in suitable carriers. This study aimed to create a water-in-oil-in-water (W1/O/W2) double emulsion system suitable for the coencapsulation of total phenolics (TP) and anthocyanins (TA) from a polyphenol-rich extract of blueberry pomace (W1). The effect of critical physical parameters for preparing stable double emulsions, namely homogenization pressure, stirring speed and time, was investigated by measuring the hydrodynamic diameter, size dispersity and zeta potential of the oil droplets, and the encapsulation efficiency of TP and TA. The oil droplets were negatively charged (negative zeta potential values), which was related to the pH and composition of W2 (whey protein isolate solution) and suggests stabilization by the charged whey proteins. Increasing W1/O/W2 microfluidization pressure from 50 to 200 MPa or homogenization speed from 6000 to 12,000 rpm significantly increased droplet diameter and zeta potential and decreased TA and TP encapsulation efficiency. Increasing W1/O/W2 homogenization time from 15 to 20 min also increased droplet diameter and zeta potential and lowered TA encapsulation efficiency, while TP encapsulation did not vary significantly. In contrast, increasing W1/O homogenization time from 5 to 10 min at 10,000 rpm markedly increased TA encapsulation efficiency and reduced droplet diameter and zeta potential. High coencapsulation rates of blueberry polyphenols and anthocyanins around 80% or greater were achieved when the oil droplets were relatively small (mean diameter < 400 nm), with low dispersity (<0.25) and a high negative surface charge (-40 mV or less). These characteristics were obtained by homogenizing for 10 min at 10,000 rpm (W1/O), then 6000 rpm for 15 min, followed by microfluidization at 50 MPa. PMID- 30279379 TI - SRSF3, a Splicer of the PKM Gene, Regulates Cell Growth and Maintenance of Cancer Specific Energy Metabolism in Colon Cancer Cells. AB - Serine and arginine rich splicing factor 3 (SRSF3), an SR-rich family protein, has an oncogenic function in various kinds of cancer. However, the detailed mechanism of the function had not been previously clarified. Here, we showed that the SRSF3 splicer regulated the expression profile of the pyruvate kinase, which is one of the rate-limiting enzymes in glycolysis. Most cancer cells express pyruvate kinase muscle 2 (PKM2) dominantly to maintain a glycolysis-dominant energy metabolism. Overexpression of SRSF3, as well as that of another splicer, polypyrimidine tract binding protein 1 (PTBP1) and heterogeneous nuclear ribonucleoprotein A1 (hnRNPA1), in clinical cancer samples supported the notion that these proteins decreased the Pyruvate kinase muscle 1 (PKM1)/PKM2 ratio, which positively contributed to a glycolysis-dominant metabolism. The silencing of SRSF3 in human colon cancer cells induced a marked growth inhibition in both in vitro and in vivo experiments and caused an increase in the PKM1/PKM2 ratio, thus resulting in a metabolic shift from glycolysis to oxidative phosphorylation. At the same time, the silenced cells were induced to undergo autophagy. SRSF3 contributed to PKM mRNA splicing by co-operating with PTBP1 and hnRNPA1, which was validated by the results of RNP immunoprecipitation (RIP) and immunoprecipitation (IP) experiments. These findings altogether indicated that SRSF3 as a PKM splicer played a positive role in cancer-specific energy metabolism. PMID- 30279381 TI - Analysis of the Bearing Capacity of Helical Pile with Hexagonal Joints. AB - This study aims to improve shafts with hexagonal joints so that they will not require welding or bolts in static load tests. In order to evaluate the bearing capacity of helical piles, two sites were selected to conduct pile installation for the field test and the pile load test. For the pile load test, a static pile load test and a dynamic pile load test were carried out, and torque was measured during pile installation in a field test to compare and analyze the expected bearing capacity and thus assess the feasibility of the method for estimating the bearing capacity. The field pile load test revealed that the bearing capacity of the gravity grout pile was the same or greater than 600 kN in the static pile load test in accordance with the AC 358 code. The non-grout pile showed a bearing capacity that was the same or smaller than 600 kN, suggesting that gravity grouting is required. Moreover, the field pile load test was used to establish the bearing capacity equation considering the torque in the pile installation, and a small number of samples were used to establish the equation, which can be used as basic data. PMID- 30279382 TI - Probing the Action of Permeation Enhancers Sodium Cholate and N-dodecyl-beta-D maltoside in a Porcine Jejunal Mucosal Explant System. AB - The small intestinal epithelium constitutes a major permeability barrier for the oral administration of therapeutic drugs with poor bioavailability, and permeation enhancers (PEs) are required to increase the paracellular and/or transcellular uptake of such drugs. Many PEs act as surfactants by perturbing cell membrane integrity and causing permeabilization by leakage or endocytosis. The aim of the present work was to study the action of sodium cholate (NaC) and N dodecyl-beta-D-maltoside (DDM), using a small intestinal mucosal explant system. At 2 mM, both NaC and DDM caused leakage into the enterocyte cytosol of the fluorescent probe Lucifer Yellow, but they also blocked the constitutive endocytotic pathway from the brush border. In addition, an increased paracellular passage of 3-kDa Texas Red Dextran into the lamina propria was observed. By electron microscopy, both PEs disrupted the hexagonal organization of microvilli of the brush border and led to the apical extrusion of vesicle-like and amorphous cell debris to the lumen. In conclusion, NaC and DDM acted in a multimodal way to increase the permeability of the jejunal epithelium both by paracellular and transcellular mechanisms. However, endocytosis, commonly thought to be an uptake mechanism that may be stimulated by PEs, was not involved in the transcellular process. PMID- 30279380 TI - Biodegradation of Some Organic Materials in Soils and Soil Constructions: Experiments, Modeling and Prevention. AB - The decomposition of natural and synthetic polymeric materials (peat, humates, biochar, strongly swelling hydrogels and other soil conditioners) in a biologically and chemically active soil environment inevitably leads to a reduced ability to improve the structure, water-retention, absorptive capacity and fertility of artificial soil constructions in urbanized ecosystems and agro landscapes (constructozems). Quantitative assessment of the biodegradation process using field and laboratory incubation experiments, as well as mathematical modeling, showed the possibility of significant (up to 30-50% per year) losses of organic matter of constructozems and a corresponding deterioration of soil quality. Incubation experiments that track the carbon dioxide emission rates of polymeric materials under given thermodynamic conditions allow for the estimation of decomposition rates in addition to an exploration on the dependence of such rates on additions of microbial inhibitors. The use of nomographs provide an opportunity to optimize long-term amendment performance in soil constructions by identifying the most favorable depths to apply amendments to ensure stable functioning during desired in-service timelines in the built environment. The results of the study are useful for geo-engineers and landscaping practitioners. PMID- 30279383 TI - Self-Adaptive Spectrum Analysis Based Bearing Fault Diagnosis. AB - Bearings are critical parts of rotating machines, making bearing fault diagnosis based on signals a research hotspot through the ages. In real application scenarios, bearing signals are normally non-linear and unstable, and thus difficult to analyze in the time or frequency domain only. Meanwhile, fault feature vectors extracted conventionally with fixed dimensions may cause insufficiency or redundancy of diagnostic information and result in poor diagnostic performance. In this paper, Self-adaptive Spectrum Analysis (SSA) and a SSA-based diagnosis framework are proposed to solve these problems. Firstly, signals are decomposed into components with better analyzability. Then, SSA is developed to extract fault features adaptively and construct non-fixed dimension feature vectors. Finally, Support Vector Machine (SVM) is applied to classify different fault features. Data collected under different working conditions are selected for experiments. Results show that the diagnosis method based on the proposed diagnostic framework has better performance. In conclusion, combined with signal decomposition methods, the SSA method proposed in this paper achieves higher reliability and robustness than other tested feature extraction methods. Simultaneously, the diagnosis methods based on SSA achieve higher accuracy and stability under different working conditions with different sample division schemes. PMID- 30279385 TI - Physical Activity and Gastric Cancer Risk in Patients with and without Helicobacter pylori Infection in A Korean Population: A Hospital-Based Case Control Study. AB - Although physical activity (PA) is beneficial for prolonging lifespan, evidence for the protective role of PA against the development of gastric cancer (GC) is not yet well established. This study assessed the association between PA and GC risk in patients with and without Helicobacter pylori (H. pylori) infection in a Korean population. In total, 415 GC patients and 830 controls were enrolled at the National Cancer Center, Korea. The International Physical Activity Questionnaire-Short Form was used to collect PA data. The odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using unconditional logistic regression models. In the H. pylori-positive group, subjects who engaged in regular exercise showed a significantly reduced risk of GC in the entire population (OR = 0.52, 95% CI = 0.38-0.70) and in females (OR = 0.60, 95% CI = 0.21-0.64). Subjects who engaged in a high level of total PA showed a significantly reduced risk of GC relative to subjects in the lowest tertile in the fully adjusted model (OR = 0.46, 95% CI = 0.32-0.65, p-trend < 0.001). There was an inverse association between PA and GC risk in the entire population, and in the H. pylori-positive subgroup. Our data indicate the need for the promotion of all domains of PA, especially for Korean populations. PMID- 30279384 TI - A Review on the Gluten-Free Diet: Technological and Nutritional Challenges. AB - Consumers, food manufacturers and health professionals are uniquely influenced by the growing popularity of the gluten-free diet. Consumer expectations have urged the food industry to continuously adjust and improve the formulations and processing techniques used in gluten-free product manufacturing. Health experts have been interested in the nutritional adequacy of the diet, as well as its effectiveness in managing gluten-related disorders and other conditions. In this review, we aim to provide a clear picture of the current motivations behind the use of gluten-free diets, as well as the technological and nutritional challenges of the diet as a whole. Alternative starches and flours, hydrocolloids, and fiber sources were found to play a complex role in mimicking the functional and sensory effects of gluten in gluten-free products. However, the quality of gluten-free alternatives is often still inferior to the gluten-containing products. Furthermore, the gluten-free diet has demonstrated benefits in managing some gluten-related disorders, though nutritional imbalances have been reported. As there is limited evidence supporting the use of the gluten-free diet beyond its role in managing gluten-related disorders, consumers are urged to be mindful of the sensorial limitations and nutritional inadequacies of the diet despite ongoing strategies to improve them. PMID- 30279386 TI - Preparation of a Defined Gluten Hydrolysate for Diagnosis and Clinical Investigations of Wheat Hypersensitivities. AB - Gluten is the trigger for celiac disease (CD), non-celiac gluten/wheat sensitivity (NCGS), and wheat allergy. An oral food challenge is often needed for diagnosis, but there are no standardized gluten challenge materials with known composition available. To fill this gap, two materials, commercially available gluten and a food-grade gluten hydrolysate (pepgluten), were extensively characterized. Pepgluten was prepared from gluten by incubation with a pepsin dietary supplement and acetic acid at 37 degrees C for 120 min. The components of pepgluten were crude protein (707 mg/g), starch (104 mg/g), water (59 mg/g), fat (47 mg/g), dietary fiber (41 mg/g) and ash (11 mg/g). The protein/peptide fraction of pepgluten (1 g) contained equivalents derived from 369 mg gliadins and 196 mg glutenins, resulting in 565 mg total gluten equivalents, 25 mg albumins/globulins, 22 mg alpha-amylase/trypsin inhibitors and 48 mg pepsin capsule proteins. The slightly acidic, dough-like smell and bitter taste of pepgluten could be completely camouflaged in multivitamin juice with bitter lemon, grapefruit juice, or vegetable and fruit smoothies. Thus, pepgluten met the criteria for placebo-controlled challenges (active and placebo materials are identical regarding appearance, taste, smell, and texture) and is appropriate as a standard preparation for the oral food challenge and clinical investigations to study wheat hypersensitivities.

AB - Many types of solutions have been studied and developed in order to give the user feedback when using touchpads, buttons, or keyboards in textile industry. Their application on textiles could allow a wide range of applications in the field of medicine, sports or the automotive industry. In this work, we introduce a novel solution that combines a 2D touchpad with an electroluminescent display (ELD). This approach physically has two circuits over a flexible textile substrate using the screen-printing technique for wearable electronics applications. Screen printing technology is widely used in the textile industry and does not require heavy investments. For the proposed solution, different layer structures are presented, considering several fabric materials and inks, to obtain the best results. PMID- 30279388 TI - Melaleuca styphelioides Sm. Polyphenols Modulate Interferon Gamma/Histamine Induced Inflammation in Human NCTC 2544 Keratinocytes. AB - Melaleuca styphelioides, known as the prickly-leaf tea tree, contains a variety of bioactive compounds. The purposes of this study were to characterize the polyphenols extracted from Melaleuca styphelioides leaves and assess their potential antioxidant and anti-inflammatory effects. The polyphenol extracts were prepared by maceration with solvents of increasing polarity. The LC/MS-MS technique was used to identify and quantify the phenolic compounds. An assessment of the radical scavenging activity of all extracts was performed using 2,2 diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azinobis-(3-ethylbenzothiazoline-6 sulphonate) (ABTS+), and ferric reducing antioxidant power (FRAP) assays. The anti-inflammatory activity was determined on interferon gamma (IFN gamma)/histamine (H)-stimulated human NCTC 2544 keratinocytes by Western blot and RT-PCR. Compared to other solvents, methanolic extract presented the highest level of phenolic contents. The most frequent phenolic compounds were quercetin, followed by gallic acid and ellagic acid. DPPH, ABTS+, and FRAP assays showed that methanolic extract exhibits strong concentration-dependent antioxidant activity. IFN-gamma/H treatment of human NCTC 2544 keratinocytes induced the secretion of high levels of the pro-inflammatory mediator inter-cellular adhesion molecule-1 (ICAM-1), nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and nuclear factor kappa B (NF-kappaB), which were inhibited by extract. In conclusion, the extract of Melaleuca styphelioides leaves is rich in flavonoids, and presents antioxidant and anti-inflammatory proprieties. It can be proposed as a useful compound to treat inflammatory skin diseases. PMID- 30279390 TI - Real-Time Lossless Compression Algorithm for Ultrasound Data Using BL Universal Code. AB - Software-based ultrasound imaging systems provide high flexibility that allows easy and fast adoption of newly developed algorithms. However, the extremely high data rate required for data transfer from sensors (e.g., transducers) to the ultrasound imaging systems is a major bottleneck in the software-based architecture, especially in the context of real-time imaging. To overcome this limitation, in this paper, we present a Binary cLuster (BL) code, which yields an improved compression ratio compared to the exponential Golomb code. Owing to the real-time encoding/decoding features without overheads, the universal code is a good solution to reduce the data transfer rate for software-based ultrasound imaging. The performance of the proposed method was evaluated using in vitro and in vivo data sets. It was demonstrated that the BL-beta code has a good stable lossless compression performance of 20%~30% while requiring no auxiliary memory or storage. PMID- 30279391 TI - Beta-Glucanemia after Coronary Artery Bypass Graft Surgery: A Case Report. AB - Blood salvage techniques are increasingly being used during surgical procedures to reduce the need for exogenous blood products. The blood recovered from the surgical field through aspiration or absorption by surgical sponges is reinfused into a patient. A 65-year old patient who underwent coronary artery bypass grafting using blood salvage techniques developed a fever on post-op day 3 and was noted to have an elevated beta-d-glucan level, a marker of systemic fungal infections. Ultimately, no fungal infection was identified, beta-d-glucan levels slowly decreased and the patient demonstrated clinical improvement. To determine whether blood salvage procedures led to his elevated beta-d-glucan levels, the surgical sponges were tested for elutable levels of beta-d-glucan. The beta-d glucan content of the eluents was measured using the Fungitell(r) IVD kit (Associates of Cape Cod, Inc.; East Falmouth, MA). The beta-d-glucan levels were found to be in concentrations 10,000-times greater than the limit of detection for human serum. While various studies have demonstrated both the immunomodulatory and pro-inflammatory effects of beta-d-glucan, the physiologic impact of such high levels of beta-d-glucan post-operatively remains unknown. Additionally, the persistence of detectable beta-d-glucan up to several weeks after surgical procedures presents a challenge for the diagnosis of invasive fungal infections. Further studies are needed to assess the beta-glucanemia related safety of surgical materials and their potential biological effects. PMID- 30279389 TI - Effects of Phytoremediation Treatment on Bacterial Community Structure and Diversity in Different Petroleum-Contaminated Soils. AB - Increased exploitation and use of petroleum resources is leading to increased risk of petroleum contamination of soil and groundwater. Although phytoremediation is a widely-used and cost-effective method for rehabilitating soils polluted by petroleum, bacterial community structure and diversity in soils undergoing phytoremediation is poorly understood. We investigate bacterial community response to phytoremediation in two distinct petroleum-contaminated soils (add prepared petroleum-contaminated soils) from northwest China, Weihe Terrace soil and silty loam from loess tableland. High-throughput sequencing technology was used to compare the bacterial communities in 24 different samples, yielding 18,670 operational taxonomic units (OTUs). The dominant bacterial groups, Proteobacteria (31.92%), Actinobacteria (16.67%), Acidobacteria (13.29%) and Bacteroidetes (6.58%), increased with increasing petroleum concentration from 3000 mg/kg-10,000 mg/kg, while Crenarchaeota (13.58%) and Chloroflexi (4.7%) decreased. At the order level, RB41, Actinomycetales, Cytophagales, envOPS12, Rhodospirillales, MND1 and Xanthomonadales, except Nitrososphaerales, were dominant in Weihe Terrace soil. Bacterial community structure and diversity in the two soils were significantly different at similar petroleum concentrations. In addition, the dominant genera were affected by available nitrogen, which is strongly associated with the plants used for remediation. Overall, the bacterial community structure and diversity were markedly different in the two soils, depending on the species of plants used and the petroleum concentration. PMID- 30279392 TI - Growth, Carcass Traits, Blood Hematology, Serum Metabolites, Immunity, and Oxidative Indices of Growing Rabbits Fed Diets Supplemented with Red or Black Pepper Oils. AB - The present study aimed to examine the impacts of the supplementation of red or black pepper oils to rabbit diet as growth promoters on New Zealand white (NZW) rabbits. One hundred and forty weaned NZW rabbits were divided randomly into seven groups in a completely randomized experiment using different quantities of red pepper oil (RPO; 0.5, 1.0, 1.5 g/kg diet) or black pepper oil (BPO; 0.5, 1.0, 1.5 g/kg diet), in addition to the control group. Compared to the control, values of live body weight (LBW) for rabbits fed either RPO or BPO enriched diets were greater. The concentrations of serum triglycerides and cholesterol were lower (p < 0.01) in the RPO- and BPO-treated groups than in the control. Immunity parameters and antioxidant indices were improved in treated groups in comparison to the control. Dietary RPO or BPO can affect some growth traits, improve immunity parameters and the antioxidant activity, and decrease the lipid profile and lipid peroxidation. The use of 0.5 g RPO/kg diet as a dietary supplement had a larger effect on growth parameters than the other treatment groups. PMID- 30279393 TI - Assessment of Long-Term Watershed Management on Reservoir Phosphorus Concentrations and Export Fluxes. AB - Source water nutrient management to prevent eutrophication requires critical strategies to reduce watershed phosphorus (P) loadings. Shanxi Drinking-Water Source Area (SDWSA) in eastern China experienced severe water quality deterioration before 2010, but showed considerable improvement following application of several watershed management actions to reduce P. This paper assessed the changes in total phosphorus (TP) concentrations and fluxes at the SDWSA outlet relative to watershed anthropogenic P sources during 2005-2016. Overall anthropogenic P inputs decreased by 21.5% over the study period. Domestic sewage, livestock, and fertilizer accounted for (mean +/- SD) 18.4 +/- 0.6%, 30.1 +/- 1.9%, and 51.5 +/- 1.5% of total anthropogenic P inputs during 2005-2010, compared to 24.3 +/- 2.7%, 8.8 +/- 10.7%, and 66.9 +/- 8.0% for the 2011-2016 period, respectively. Annual average TP concentrations in SDWSA decreased from 0.041 +/- 0.019 mg/L in 2009 to 0.025 +/- 0.013 mg/L in 2016, a total decrease of 38.2%. Annual P flux exported from SDWSA decreased from 0.46 +/- 0.04 kg P/(ha.a) in 2010 to 0.25 +/- 0.02 kg P/(ha.a) in 2016, a decrease of 44.9%. The success in reducing TP concentrations was mainly due to the development of domestic sewage/refuse collection/treatment and improved livestock management. These P management practices have prevented harmful algal blooms, providing for safe drinking water. PMID- 30279394 TI - Research on Formation Conditions of the Ultrafine-Grained Structure of the Cylindrical Parts Manufactured by Power Spinning Based on Small Strains. AB - Two different methods, power spinning and annealing (PSA), quenching and power spinning followed by annealing (QPSA), for manufacturing the cylindrical parts with ultrafine-grained (UFG) structure were reviewed, the dislocation density and microstructural evolution during the two different processes of PSA and QPSA were further studied. The results show that the required strains for obtaining the UFG structure by power spinning is only 0.92 when the initial microstructure of the material is in the phase of lath martensite. The dislocation density and storage energy are increased to 10 times that of the blank after quenching and power spinning and decreased to the level of the blank after recrystallization annealing. Microstructures with fine grain size after quenching, storage energy of 1.8 * 105 kJ/m3 obtained after power spinning and second phase particle with nano-scale precipitated during annealing are the necessary formation conditions for manufacturing the cylindrical parts with UFG structure based on small strains. Compared with the original tubular blank, the mechanical properties of the spun parts with UFG structure improves significantly. The tensile strength and hardness of the spun parts manufactured by QPSA method is 815 MPa and 305 HV, respectively, and the elongation is 17.5%. PMID- 30279396 TI - Resolving Digital Staphylococcal Osteomyelitis Using Bacteriophage-A Case Report. AB - Infections involving diabetic foot ulcers (DFU) are a major public health problem and have a substantial negative impact on patient outcomes. Osteomyelitis in an ulcerated foot substantially increases the difficulty of successful treatment. While literature suggests that osteomyelitis in selected patients can sometimes be treated conservatively, with no, or minimal removal of bone, we do not yet have clear treatment guidelines and the standard treatment failure fallback remains amputation. The authors report on the successful treatment, with a long term follow up, of a 63 YO diabetic female with distal phalangeal osteomyelitis using bacteriophage, a form of treatment offering the potential for improved outcomes in this era of escalating antibiotic resistance and the increasingly recognized harms associated with antibiotic therapy. PMID- 30279395 TI - Meat, Meat Products and Seafood as Sources of Energy and Nutrients in the Average Polish Diet. AB - The aim of this study was to identify the share of meat, meat products and seafood in the contribution of energy and 22 nutrients to the average Polish diet. Data from the nationally representative sample of Polish population (2016 Household Budget Survey) on meat and seafood product consumption from 38,886 households (n = 99,230) were calculated into one person per month. The analyses were conducted for seven food groups (e.g., red meat, poultry) and 16 products (e.g., beef, chicken). Approximately 18.5% of energy is delivered from the sources such as meat, meat products and seafood, providing a higher percentage of 18 nutrients to the diet (e.g., 56.0% of vitamin B12, 52.3% of niacin, 44.9% of cholesterol, 41.5% of protein, 41.4%of vitamin D, 37.6% of monounsaturated fatty acids (MUFA), 37.4% of thiamin, 33.8% of zinc, 32.0% of total fats, 30.3% of saturated fatty acids (SFA), 29.6% of vitamin B6, 25.3% of riboflavin, 24.9% of phosphorus, 24.8% of iron, 22.5% of vitamin A, 21.6% of polyunsaturated fatty acids (PUFA) and 20.3% of sodium). For the contribution of 18 nutrients and energy, processed meat products were ranked first. These results should be taken into consideration in order to compose diets with adequate energy and nutrient contribution and also to analyze benefits and risk resulting from the current level of consumption of red and processed meat, fish and other seafood. PMID- 30279397 TI - Effects of Long Chain Omega-3 Polyunsaturated Fatty Acids on Brain Function in Mildly Hypertensive Older Adults. AB - Purported benefits of long chain omega-3 polyunsaturated fatty acid (LCn-3PUFA) for brain function may be attributable, at least in part, to improved cerebral perfusion. A pilot randomised controlled trial was undertaken to investigate effects of taking a DHA-rich fish oil supplement for 20 weeks on cerebrovascular function, mood and cognitive performance. Borderline hypertensives aged 40-85 years with low habitual LCn-3PUFA intake took four capsules/day of EPAX (1600 mg DHA + 400 mg EPA) or placebo (corn oil). Cerebrovascular function was assessed at baseline and after 20 weeks in 38 completers (19 on each supplement) using transcranial Doppler ultrasound of blood flow in the middle cerebral artery at rest and whilst performing a battery of cognitive tasks (neurovascular coupling). The primary outcome, cerebrovascular responsiveness (CVR) to hypercapnia, increased 26% (p = 0.024) in women; there was no change in men. In contrast, neurovascular coupling increased significantly (p = 0.01 for the overall response) in men only; the latter correlated with an increase of EPA in erythrocytes (r = 0.616, p = 0.002). There was no associated improvement of mood or cognition in either men or women. These preliminary observations indicate that LCn-3PUFA supplementation has the potential to enhance blood flow in the brain in response to both hypercapnic and cognitive stimuli. Future studies should examine differential effects of EPA and DHA and take account of the gender differences in responsiveness to supplementation. PMID- 30279398 TI - Characterization of MS/MS Product Ions for the Differentiation of Structurally Isomeric Pesticides by High-Resolution Mass Spectrometry. AB - Structural isomeric pesticides are used in agriculture and may be challenging to differentiate for accurate identification in pesticide monitoring programs. Due to structural similarity, isomeric pesticides are difficult to separate chromatographically, and thus, their accurate identification may rely solely on mass spectrometric analysis (MS). In this study, we challenged the ability of high-resolution quadrupole-orbitrap (Q-Orbitrap) mass spectrometry to produce and evaluate the tandem mass spectrometry (MS/MS) product ions for the selected five pairs of isomeric pesticides from different classes: Pebulate and vernolate, methiocarb and ethiofencarb, uniconazole and cyproconazole, sebuthylazine and terbuthylazine, and orbencarb and thiobencarb. The use of Q-Orbitrap instrument with a mass error <3 ppm allowed proposed elucidation of the product ion structures with consideration of the ion formulae, data interpretation, and literature searches. Product ions unique to pebulate, vernolate, methiocarb, ethiofencarb, and uniconazole were observed. Elucidation of the observed MS/MS product ion structures was conducted, and the fragmentation pathways were proposed. This information is valuable to increase selectivity in MS/MS analysis and differentiate isomeric pesticides, and thereby reduce the rates of false positives in pesticide monitoring programs.

PMID- 30279401 TI - Possible Emergence of Sequence Specific RNA Aminoacylation via Peptide Intermediary to Initiate Darwinian Evolution and Code Through Origin of Life. AB - One of the most intriguing questions in biological science is how life originated on Earth. A large number of hypotheses have been proposed to explain it, each putting an emphasis on different events leading to functional translation and self-sustained system. Here, we propose a set of interactions that could have taken place in the prebiotic environment. According to our hypothesis, hybridization-induced proximity of short aminoacylated RNAs led to the synthesis of peptides of random sequence. We postulate that among these emerged a type of peptide(s) capable of stimulating the interaction between specific RNAs and specific amino acids, which we call "bridge peptide" (BP). We conclude that translation should have emerged at the same time when the standard genetic code begun to evolve due to the stabilizing effect on RNA-peptide complexes with the help of BPs. Ribosomes, ribozymes, and the enzyme-directed RNA replication could co-evolve within the same period, as logical outcome of RNA-peptide world without the need of RNA only self-sustained step. PMID- 30279399 TI - Characterization of Histone Genes from the Bivalve Lucina Pectinata. AB - Lucina pectinata is a clam that lives in sulfide-rich environments and houses intracellular sulfide-oxidizing endosymbionts. To identify new Lucina pectinata proteins, we produced libraries for genome and transcriptome sequencing and assembled them de novo. We searched for histone-like sequences using the Lucina pectinata histone H3 partial nucleotide sequence against our previously described genome assembly to obtain the complete coding region and identify H3 coding sequences from mollusk sequences in Genbank. Solen marginatus histone nucleotide sequences were used as query sequences using the genome and transcriptome assemblies to identify the Lucina pectinata H1, H2A, H2B and H4 genes and mRNAs and obtained the complete coding regions of the five histone genes by RT-PCR combined with automated Sanger DNA sequencing. The amino acid sequence conservation between the Lucina pectinata and Solen marginatus histones was: 77%, 93%, 83%, 96% and 97% for H1, H2A, H2B, H3 and H4, respectively. As expected, the H3 and H4 proteins were the most conserved and the H1 proteins were most similar to H1's from aquatic organisms like Crassostrea gigas, Aplysia californica, Mytilus trossulus and Biomphalaria glabrata. The Lucina pectinata draft genome and transcriptome assemblies, obtained by semiconductor sequencing, were adequate for identification of conserved proteins as evidenced by our results for the histone genes. PMID- 30279402 TI - Preclinical Models of Pediatric Brain Tumors-Forging Ahead. AB - Approximately five out of 100,000 children from 0 to 19 years old are diagnosed with a brain tumor. These children are treated with medication designed for adults that are highly toxic to a developing brain. Those that survive are at high risk for a lifetime of limited physical, psychological, and cognitive abilities. Despite much effort, not one drug exists that was designed specifically for pediatric patients. Stagnant government funding and the lack of economic incentives for the pharmaceutical industry greatly limits preclinical research and the development of clinically applicable pediatric brain tumor models. As more data are collected, the recognition of disease sub-groups based on molecular heterogeneity increases the need for designing specific models suitable for predictive drug screening. To overcome these challenges, preclinical approaches will need continual enhancement. In this review, we examine the advantages and shortcomings of in vitro and in vivo preclinical pediatric brain tumor models and explore potential solutions based on past, present, and future strategies for improving their clinical relevancy. PMID- 30279403 TI - New Perspectives on the Use of Cannabis in the Treatment of Psychiatric Disorders. AB - Following the discovery of the endocannabinoid system and its potential as a therapeutic target for various pathological conditions, growing interest led researchers to investigate the role of cannabis and its derivatives for medical purposes. The compounds Delta9-tetrahydrocannabinol and cannabidiol are the most abundant phytocannabinoids found in cannabis extracts, as well as the most studied. The present review aims to provide an overview of the current evidence for their beneficial effects in treating psychiatric disorders, including schizophrenia, anxiety, and depression. Nevertheless, further investigations are required to clarify many pending issues, especially those relative to the assessment of benefits and risks when using cannabis for therapeutic purposes, thereby also helping national and federal jurisdictions to remain updated. PMID- 30279404 TI - Identification of Differentially Expressed Genes in BALB/c Mouse Liver upon Primary Infection with DENV1 and Sequential Heterologous Infection with DENV2. AB - Dengue virus (DENV) results in 100 million cases of infections and 22,000 deaths per year. Liver involvement, thrombocytopenia, haemorrhage and plasma leakage are characteristic manifestations of severe forms of DENV infection. However, the molecular pathways of DENV infection have not been comprehensively studied compared to the host immunological responses. We performed an in vivo study using the BALB/c mouse model with a modified mRNA differential display methodology (GeneFishingTM) using the annealing control primer (ACP) system to capture differentially expressed genes (DEGs) in mice liver upon primary infection with DENV1 and sequential heterologous infection with DENV2. Secondary heterologous infection with DENV2 was carried out at Immunoglobulin IgM and IgG peaks following the primary DENV1 infection with the hope of determining any potential effect antibodies IgM and IgG may have on sequential heterologous infection. 30 DEGs were identified and sequenced across all three treatment groups and they belong to a variety of important pathways such as apoptosis, innate immune response, inflammatory response, metabolic processes and oxidative stress. Analysis of differentially expressed genes in response to viral infection offers valuable knowledge about the dynamic and complex association between host cell and the virus. Furthermore, some DEGs identified support DENV induced liver damage. PMID- 30279405 TI - Polymeric Nanocarriers for the Delivery of Antimalarials. AB - Malaria is an infectious disease caused by a protozoan parasite which is transmitted by female Anopheles mosquitoes around tropical and sub-tropical regions. Half of the world's population is at risk of being infected by malaria. This mainly includes children, pregnant women and people living with chronic diseases. The main factor that has contributed to the spread of this disease is the increase in the number of drug-resistant parasites. To overcome drug resistance, researchers have developed drug delivery systems from biodegradable polymers for the loading of antimalarials. The drug delivery systems were characterized by distinct features such as good biocompatibility, high percentage drug encapsulation, reduced drug toxicity and targeted drug delivery. In this review article, we highlight the various types of drug delivery systems developed from polymeric nanocarriers used for the delivery of antimalarials. PMID- 30279406 TI - Development of a Rapid Fluorescent Immunochromatographic Test to Detect Respiratory Syncytial Virus. AB - Human respiratory syncytial virus (RSV) is one of the most common viruses infecting the respiratory tracts of infants. The rapid and sensitive detection of RSV is important to minimize the incidence of infection. In this study, novel monoclonal antibodies (mAbs; B11A5 and E8A11) against RSV nucleoprotein (NP) were developed and applied to develop a rapid fluorescent immunochromatographic strip test (FICT), employing europium nanoparticles as the fluorescent material. For the FICT, the limits of detection of the antigen and virus were 1.25 ug/mL and 4.23 * 106 TCID50/mL, respectively, corresponding to 4.75 * 106 +/- 5.8 *105 (mean +/- SD) RNA copy numbers per reaction mixture for RSV NP. A clinical study revealed a sensitivity of 90% (18/20) and specificity of 98.18% (108/110) for RSV detection when comparing the performance to that of reverse transcription polymerase chain reaction (RT-PCR), representing a 15% improvement in sensitivity over the SD Bioline rapid kit. This newly developed FICT could be a useful tool for the rapid diagnosis of RSV infection. PMID- 30279407 TI - Association of ERCC2 Gene Polymorphisms with Susceptibility to Diffuse Large B Cell Lymphoma. AB - BACKGROUND The objective of this study was to detect the association between ERCC excision repair 2, TFIIH core complex helicase subunit (ERCC2) gene polymorphisms and diffuse large B-cell lymphoma (DLBCL) susceptibility. MATERIAL AND METHODS This study used a case-control design. ERCC2 gene rs1799793 (Asp312Asn) and rs13181 (Lys751Gln) polymorphisms were genotyped by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) both in DLBCL patients and healthy controls. The association between ERCC2 gene polymorphisms and DLBCL risk was assessed by chi2 test. Odds ratios (ORs) with corresponding 95% confidence intervals (95% CIs) were used to address the association strength. Subgroup analyses were also performed to investigate the genetic effects of ERCC2 polymorphisms on clinical characteristics of DLBCL patients. RESULTS A significant association was discovered between the rs1799793 A allele and increased DLBCL risk (P=0.031, OR=1.928, 95% CI=1.052-3.534). The C allele of rs13181 was obviously associated with elevated DLBCL susceptibility (P=0.047, OR=1.820, 95% CI=1.002-3.305). The subgroup analysis demonstrated that rs1799793 and rs13181 polymorphisms had no relationship with serum lactate dehydrogenase level, nidus number, B-symptoms, Ann Arbor stages, or immunological types in DLBCL cases (P>0.05 for all). CONCLUSIONS Minor allele carriers of ERCC2 gene rs1799793 (Asp312Asn) and rs13181 (Lys751Gln) polymorphisms had higher susceptibility to DLBCL. PMID- 30279408 TI - Endoscopic Retrograde Cholangiopancreatography (ERCP) with Laparotomic Small Intestinal Incision Approach for Extraction of a Common Bile Duct (CBD) Stone Following Total Gastrectomy and Roux-en-Y (R-Y) Anastomosis: A Case Report. AB - BACKGROUND Endoscopic retrograde cholangiopancreatography for common bile duct stone in patients who underwent gastrectomy and Roux-en-Y anastomosis is challenging. We report a case in which we performed endoscopic retrograde cholangiopancreatography through a small-intestinal incision approach for a common bile duct stone, which had developed after total gastrectomy and Roux-en-Y anastomosis. CASE REPORT An 86-year-old woman with a history of laparoscopic assisted total gastrectomy and R-Y anastomosis and incision of the common bile duct and cholecystectomy for common bile duct stone by open surgery 3 years ago presented with abdominal pain. Examination revealed a 10-mm stone in the lower part of common bile duct. We planned a combined endoscopic and open surgical approach. An incision on the Y limb of the Roux-en-Y anastomosis 20 cm from the jejunojejunal anastomosis and insertion of an endoscope through this opening were performed to extract the common bile duct stone. The patient was discharged on postoperative day 22 without complications. CONCLUSIONS For a patient with a common bile duct stone, who underwent gastrectomy and Roux-en-Y anastomosis, with firm adhesions at the porta hepatis, combined endoscopy and open surgery using a small-intestinal incision approach can be effective when small-bowel endoscopes are unavailable or the cannulation to Vater's papilla by them is difficult. PMID- 30279409 TI - In vivo neutralization of dendrotoxin-mediated neurotoxicity of black mamba venom by oligoclonal human IgG antibodies. AB - The black mamba (Dendroaspis polylepis) is one of the most feared snake species of the African savanna. It has a potent, fast-acting neurotoxic venom comprised of dendrotoxins and alpha-neurotoxins associated with high fatality in untreated victims. Current antivenoms are both scarce on the African continent and present a number of drawbacks as they are derived from the plasma of hyper-immunized large mammals. Here, we describe the development of an experimental recombinant antivenom by a combined toxicovenomics and phage display approach. The recombinant antivenom is based on a cocktail of fully human immunoglobulin G (IgG) monoclonal antibodies capable of neutralizing dendrotoxin-mediated neurotoxicity of black mamba whole venom in a rodent model. Our results show the potential use of fully human monoclonal IgGs against animal toxins and the first use of oligoclonal human IgG mixtures against experimental snakebite envenoming. PMID- 30279410 TI - A polygenic p factor for major psychiatric disorders. AB - It has recently been proposed that a single dimension, called the p factor, can capture a person's liability to mental disorder. Relevant to the p hypothesis, recent genetic research has found surprisingly high genetic correlations between pairs of psychiatric disorders. Here, for the first time, we compare genetic correlations from different methods and examine their support for a genetic p factor. We tested the hypothesis of a genetic p factor by applying principal component analysis to matrices of genetic correlations between major psychiatric disorders estimated by three methods-family study, genome-wide complex trait analysis, and linkage-disequilibrium score regression-and on a matrix of polygenic score correlations constructed for each individual in a UK representative sample of 7 026 unrelated individuals. All disorders loaded positively on a first unrotated principal component, which accounted for 57, 43, 35, and 22% of the variance respectively for the four methods. Our results showed that all four methods provided strong support for a genetic p factor that represents the pinnacle of the hierarchical genetic architecture of psychopathology.

AB - Thermal radiation can be substantially enhanced in the near-field scenario due to the tunneling of evanescent waves. Monolayer graphene could play a vital role in this process owing to its strong infrared plasmonic response, however, which still lacks an experimental verification due to the technical challenges. Here, we manage to make a direct measurement about plasmon-mediated thermal radiation between two macroscopic graphene sheets using a custom-made setup. Super Planckian radiation with efficiency 4.5 times larger than the blackbody limit is observed at a 430-nm vacuum gap on insulating silicon hosting substrates. The positive role of graphene plasmons is further confirmed on conductive silicon substrates which have strong infrared loss and thermal emittance. Based on these, a thermophotovoltaic cell made of the graphene-silicon heterostructure is lastly discussed. The current work validates the classic thermodynamical theory in treating graphene and also paves a way to pursue the application of near-field thermal management.

Carotid body denervation has been shown to have a profound effect on airway hyper-responsiveness in animal models but a mechanistic explanation is lacking. Here we demonstrate, using a rat model of asthma (OVA-sensitized), that carotid body activation during airborne allergic provocation is caused by systemic release of lysophosphatidic acid (LPA). Carotid body activation by LPA involves TRPV1 and LPA-specific receptors, and induces parasympathetic (vagal) activity. We demonstrate that this activation is sufficient to cause acute bronchoconstriction. Moreover, we show that prophylactic administration of TRPV1 (AMG9810) and LPA (BrP-LPA) receptor antagonists prevents bradykinin-induced asthmatic bronchoconstriction and, if administered following allergen exposure, reduces the associated respiratory distress. Our discovery provides mechanistic insight into the critical roles of carotid body LPA receptors in allergen-induced respiratory distress and suggests alternate treatment options for asthma.

AB - Female meiotic divisions are extremely asymmetric, producing large oocytes and small polar bodies (PBs). In mouse oocytes, the spindle relocates to the cortex before anaphase of meiosis I (MI). It is presumed that by displacing the future midzone, pre-anaphase spindle repositioning alone ensures asymmetry. But how subsequent anaphase events might contribute to asymmetric PB extrusion (PBE) is unknown. Here, we find that inactivation of cyclin-dependent kinase 1 (Cdk1) induces anaphase and simultaneously triggers cytoplasmic formin-mediated F-actin polymerisation that propels the spindle into the cortex causing it to protrude while anaphase progresses. Significantly, if post-anaphase-onset spindle migration fails, protrusion and asymmetry are severely threatened even with intact pre-anaphase migration. Conversely, post-anaphase migration can completely compensate for failed pre-anaphase migration. These data identify a cell-cycle triggered phase of spindle displacement occurring after anaphase-onset, which, by inducing protrusion, is necessary for extreme asymmetry in mouse oocytes and uncover a pathway for maximising unequal division.

PMID- 30279415 TI - Molecular architecture and regulation of BCL10-MALT1 filaments. AB - The CARD11-BCL10-MALT1 (CBM) complex triggers the adaptive immune response in lymphocytes and lymphoma cells. CARD11/CARMA1 acts as a molecular seed inducing BCL10 filaments, but the integration of MALT1 and the assembly of a functional CBM complex has remained elusive. Using cryo-EM we solved the helical structure of the BCL10-MALT1 filament. The structural model of the filament core solved at 4.9 A resolution identified the interface between the N-terminal MALT1 DD and the BCL10 caspase recruitment domain. The C-terminal MALT1 Ig and paracaspase domains protrude from this core to orchestrate binding of mediators and substrates at the filament periphery. Mutagenesis studies support the importance of the identified BCL10-MALT1 interface for CBM complex assembly, MALT1 protease activation and NF kappaB signaling in Jurkat and primary CD4 T-cells. Collectively, we present a model for the assembly and architecture of the CBM signaling complex and how it functions as a signaling hub in T-lymphocytes. PMID- 30279416 TI - Two-dimensional amorphous NiO as a plasmonic photocatalyst for solar H2 evolution. AB - Amorphous materials are usually evaluated as photocatalytically inactive due to the amorphous nature-induced self-trapping of tail states, in spite of their achievements in electrochemistry. NiO crystals fail to act as an individual reactor for photocatalytic H2 evolution because of the intrinsic hole doping, regardless of their impressive cocatalytic ability for proton/electron transfer. Here we demonstrate that two-dimensional amorphous NiO nanostructure can act as an efficient and robust photocatalyst for solar H2 evolution without any cocatalysts. Further, the antenna effect of surface plasmon resonance can be introduced to construct an incorporate antenna-reactor structure by increasing the electron doping. The solar H2 evolution rate is improved by a factor of 19.4 through the surface plasmon resonance-mediated charge releasing. These findings thus open a door to applications of two-dimensional amorphous NiO as an advanced photocatalyst. PMID- 30279417 TI - Dye-incorporated coordination polymers for direct photocatalytic trifluoromethylation of aromatics at metabolically susceptible positions. AB - Direct trifluoromethylation of unactivated aromatic rings at metabolically susceptible positions is highly desirable in pharmaceutical applications. By incorporating thiophenes into the backbone of triphenylamine to enlarge its pi system, a new approach for constructing coordination polymers is reported for direct trifluoromethylation without prefunctionalization of the aryl precursors. The improved light-harvesting ability and well-modulated excited state redox potential of the designed polymers endow the generated CF3 radicals with suitable reactivity and enhance radical adduct oxidation in pores. The well-configurated interactions between the organic ligands distort the coordination geometry to create active interaction sites within the coordination polymer; thus, the substrates could be docked near the photoredox-active centres. The synergistic electronic and spatial effects in the confined pores balance the contradictory demands of electronic effects and reaction dynamics, achieving regio- and diastereoselective discrimination among reaction sites with unremarkable electronic/steric differences. PMID- 30279418 TI - Clinical value of bioelectrical properties of cancerous tissue in advanced epithelial ovarian cancer patients. AB - Currently, there are no valid pre-operatively established biomarkers or algorithms that can accurately predict surgical and clinical outcome for patients with advanced epithelial ovarian cancer (EOC). In this study, we suggest that profiling of tumour parameters such as bioelectrical-potential and metabolites, detectable by electronic sensors, could facilitate the future development of devices to better monitor disease and predict surgical and treatment outcomes. Biopotential was recorded, using a potentiometric measurement system, in ex vivo paired non-cancerous and cancerous omental tissues from advanced stage EOC (n = 36), and lysates collected for metabolite measurement by microdialysis. Consistently different biopotential values were detected in cancerous tissue versus non-cancerous tissue across all cases (p < 0.001). High tumour biopotential levels correlated with advanced tumour stage (p = 0.048) and tumour load, and negatively correlated with stroma. Within our EOC cohort and specifically the high-grade serous subtype, low biopotential levels associated with poorer progression-free survival (p = 0.0179, p = 0.0143 respectively). Changes in biopotential levels significantly correlated with common apoptosis related pathways. Lactate and glucose levels measured in paired tissues showed significantly higher lactate/glucose ratio in tissues with low biopotential (p < 0.01, n = 12). Our study proposes the feasibility of biopotential and metabolite monitoring as a biomarker modality profiling EOC to predict surgical and clinical outcomes. PMID- 30279419 TI - Permissiveness to form pluripotent stem cells may be an evolutionarily derived characteristic in Mus musculus. AB - Mus musculus is the only known species from which embryonic stem cells (ESC) can be isolated under conditions requiring only leukemia inhibitory factor (LIF). Other species are non-permissive in LIF media, and form developmentally primed epiblast stem cells (EpiSC) similar to cells derived from post-implantation, egg cylinders. To evaluate whether non-permissiveness extends to induced pluripotent stem cells (iPSC), we derived iPSC from the eight founder strains of the mouse Collaborative Cross. Two strains, NOD/ShiLtJ and the WSB/EiJ, were non permissive, consistent with the previous classification of NOD/ShiLtJ as non permissive to ESC derivation. We determined non-permissiveness is recessive, and that non-permissive genomes do not compliment. We overcame iPSC non permissiveness by using GSK3B and MEK inhibitors with serum, a technique we termed 2iS reprogramming. Although used for ESC derivation, GSK3B and MEK inhibitors have not been used during iPSC reprogramming because they inhibit survival of progenitor differentiated cells. iPSC derived in 2iS are more transcriptionally similar to ESC than EpiSC, indicating that 2iS reprogramming acts to overcome genetic background constraints. Finally, of species tested for ESC or iPSC derivation, only some M. musculus strains are permissive under LIF culture conditions suggesting that this is an evolutionarily derived characteristic in the M. musculus lineage. PMID- 30279421 TI - Motor recruitment to the TIM23 channel's lateral gate restricts polypeptide release into the inner membrane. AB - The presequence translocase of the mitochondrial inner membrane (TIM23 complex) facilitates anterograde precursor transport into the matrix and lateral release of precursors with stop-transfer signal into the membrane (sorting). Sorting requires precursor exit from the translocation channel into the lipid phase through the lateral gate of the TIM23 complex. How the two transport modes are regulated and balanced against each other is unknown. Here we show that the import motor J-protein Pam18, which is essential for matrix import, controls lateral protein release into the lipid bilayer. Constitutively translocase associated Pam18 obstructs lateral precursor transport. Concomitantly, Mgr2, implicated in precursor quality control, is displaced from the translocase. We conclude that during motor-dependent matrix protein transport, the transmembrane segment of Pam18 closes the lateral gate to promote anterograde polypeptide movement. This finding explains why a motor-free form of the translocase facilitates the lateral movement of precursors with a stop-transfer signal. PMID- 30279423 TI - Design of polarization-insensitive high-visibility silicon-on-insulator quantum interferometer. AB - We based on integrated silicon-on-insulator platforms design the key components of an on-chip interferometer, beam splitter and directional coupler included, valid in high-visibility interference at telecommunication wavelengths. Special attention is given to the equal-proportion beam splitting and directional coupling, which is achieved by carefully designing the geometric dimension of multi-mode interferometer structure. The proposed interferometer facilitates low loss, broad operating bandwidth, anticipated large tolerance on size variation induced in fabrication procedures, based on a particular wafer with silicon layer thickness of 320 nm. The most highlight property of polarization-insensitive, enables the path-selective qubits generation for bi-polarization that further makes possible quantum key distribution using high dimensional protocols. We numerically demonstrate interference at 1550 nm with visibilities of 99.50% and 93.99% for transverse-electric and transverse-magnetic polarization, respectively, revealing that the proposed interferometer structure is well capable of on-chip optical control especially in quantum optics regime. PMID- 30279420 TI - Dereplication of microbial metabolites through database search of mass spectra. AB - Natural products have traditionally been rich sources for drug discovery. In order to clear the road toward the discovery of unknown natural products, biologists need dereplication strategies that identify known ones. Here we report DEREPLICATOR+, an algorithm that improves on the previous approaches for identifying peptidic natural products, and extends them for identification of polyketides, terpenes, benzenoids, alkaloids, flavonoids, and other classes of natural products. We show that DEREPLICATOR+ can search all spectra in the recently launched Global Natural Products Social molecular network and identify an order of magnitude more natural products than previous dereplication efforts. We further demonstrate that DEREPLICATOR+ enables cross-validation of genome mining and peptidogenomics/glycogenomics results. PMID- 30279422 TI - The potential of eye-tracking as a sensitive measure of behavioural change in response to intervention. AB - One challenge to the development of effective interventions to support learning and behavioural change in neurodevelopmental disorders is a lack of suitable outcome measures. Eye-tracking has been used widely to chart cognitive development and clinically-relevant group differences in many populations. This proof-of-concept study investigates whether it also has the potential to act as a marker of treatment effects, by testing its sensitivity to differential change over a short period of exposure to an iPad app in typically developing children. The app targets a key skill in early social communication development, by rewarding attention to people, operationalised via a finger-tap on screen. We measured attention to images taken from the app, and a selection of matched stimuli to test generalisation of effects, at baseline and two weeks later. Children were assigned to either an app-exposure or no-app condition in the intervening period. The app exposure group showed increases in fixation on people for images from the app, and for distant-generalisation photographs, at high levels of complexity. We conclude that, with careful selection of stimuli, eye tracking has the potential to make a valuable contribution to the range of outcome measures available for psycho-behavioural interventions in neurodevelopmental disorders. PMID- 30279424 TI - Electromagnetic Fields Due to the Wake of a Moving Slender Body in a Finite-Depth Ocean with Density Stratification. AB - Weak electric currents are induced in moving seawater by cutting the geomagnetic fields. These electric currents can produce measurable electromagnetic fields that may be used for some purposes such as monitoring of ocean internal waves. This article is aimed at presenting the procedure to calculate the electromagnetic fields owing to the wake raised by an undersea moving slender body. A pair of Havelock point sources are introduced to model the moving body, which generate the similar wake at places far from the body. The ocean is taken to be of finite-depth with density stratification due to thermocline. Three distinct forms of water-flow wake can be identified, the free-surface Kelvin wake, the internal interfacial wake, and the localized volume wake. The electric currents evoked by the motional wake may produce observable electromagnetic fields, which may be solved using rigorous electromagnetic field theory. At the sea level, the magnitudes of the induced electric field and magnetic field are on the order of a few microvolts per meter and one nano-Tesla, respectively, which are appreciable in terms of nowadays marine electric and magnetic sensors. PMID- 30279425 TI - Increased TIMP-3 expression alters the cellular secretome through dual inhibition of the metalloprotease ADAM10 and ligand-binding of the LRP-1 receptor. AB - The tissue inhibitor of metalloproteinases-3 (TIMP-3) is a major regulator of extracellular matrix turnover and protein shedding by inhibiting different classes of metalloproteinases, including disintegrin metalloproteinases (ADAMs). Tissue bioavailability of TIMP-3 is regulated by the endocytic receptor low density-lipoprotein receptor-related protein-1 (LRP-1). TIMP-3 plays protective roles in disease. Thus, different approaches have been developed aiming to increase TIMP-3 bioavailability, yet overall effects of increased TIMP-3 in vivo have not been investigated. Herein, by using unbiased mass-spectrometry we demonstrate that TIMP-3-overexpression in HEK293 cells has a dual effect on shedding of transmembrane proteins and turnover of soluble proteins. Several membrane proteins showing reduced shedding are known as ADAM10 substrates, suggesting that exogenous TIMP-3 preferentially inhibits ADAM10 in HEK293 cells. Additionally identified shed membrane proteins may be novel ADAM10 substrate candidates. TIMP-3-overexpression also increased extracellular levels of several soluble proteins, including TIMP-1, MIF and SPARC. Levels of these proteins similarly increased upon LRP-1 inactivation, suggesting that TIMP-3 increases soluble protein levels by competing for their binding to LRP-1 and their subsequent internalization. In conclusion, our study reveals that increased levels of TIMP-3 induce substantial modifications in the cellular secretome and that TIMP-3-based therapies may potentially provoke undesired, dysregulated functions of ADAM10 and LRP-1. PMID- 30279426 TI - OligoPVP: Phenotype-driven analysis of individual genomic information to prioritize oligogenic disease variants. AB - An increasing number of disorders have been identified for which two or more distinct alleles in two or more genes are required to either cause the disease or to significantly modify its onset, severity or phenotype. It is difficult to discover such interactions using existing approaches. The purpose of our work is to develop and evaluate a system that can identify combinations of alleles underlying digenic and oligogenic diseases in individual whole exome or whole genome sequences. Information that links patient phenotypes to databases of gene phenotype associations observed in clinical or non-human model organism research can provide useful information and improve variant prioritization for genetic diseases. Additional background knowledge about interactions between genes can be utilized to identify sets of variants in different genes in the same individual which may then contribute to the overall disease phenotype. We have developed OligoPVP, an algorithm that can be used to prioritize causative combinations of variants in digenic and oligogenic diseases, using whole exome or whole genome sequences together with patient phenotypes as input. We demonstrate that OligoPVP has significantly improved performance when compared to state of the art pathogenicity detection methods in the case of digenic diseases. Our results show that OligoPVP can efficiently prioritize sets of variants in digenic diseases using a phenotype-driven approach and identify etiologically important variants in whole genomes. OligoPVP naturally extends to oligogenic disease involving interactions between variants in two or more genes. It can be applied to the identification of multiple interacting candidate variants contributing to phenotype, where the action of modifier genes is suspected from pedigree analysis or failure of traditional causative variant identification. PMID- 30279427 TI - The terpenes of leaves, pollen, and nectar of thyme (Thymus vulgaris) inhibit growth of bee disease-associated microbes. AB - Honey bees are highly prone to infectious diseases, causing colony losses in the worst case. However, they combat diseases through a combination of their innate immune system and social defence behaviours like foraging for health-enhancing plant products (e.g. nectar, pollen and resin). Plant secondary metabolites are not only highly active against bacteria and fungi, they might even enhance selective foraging and feeding decisions in the colony. Here, we tested six major plant terpenes and their corresponding acetates, characterizing six natural Thymus vulgaris chemotypes, for their antimicrobial activity on bacteria associated with European foulbrood. Comparison of the inhibitory activity revealed the highest activity for carvacrol and thymol whereas the acetates mostly did not inhibit bacterial growth. All terpenes and acetates are present in the nectar and pollen of thyme, with pollen containing concentrations higher by several orders of magnitude. The physiological response was tested on forager and freshly emerged bees by means of antennal electroantennography. Both responded much stronger to geraniol and trans-sabinene hydrate compared to carvacrol and thymol. In conclusion, bee-forageable thyme product terpenes (mainly from pollen) yield effective antibiotic activity by reducing the growth of bee disease associated bacteria and can be detected with different response levels by the honey bees' antennae. This is a further step forward in understanding the complex pathogen-pollinator-plant network. PMID- 30279428 TI - Exposure to heat-stress environment affects the physiology, circulation levels of cytokines, and microbiome in dairy cows. AB - The microbiome has emerged as a new player on behavior, physiology and stress because of its significant effects on the brain-gut axis. The aim of this study was to increase our understanding of brain-gut function in dairy cows. We investigated the effects of a heat-stress (HS) environment and individual differences of heat sensitivity (IH) on bovine physiological characteristics and microbial composition. Results indicate that both HS and IH increased rectal temperature (RT) (P < 0.05). An HS environment increased plasma, as well as milk cortisol and cytokines in plasma; however, it decreased plasma, and milk oxytocin, triiodothyronine, and thyroxine (P < 0.05) levels. Exposure to an HS environment reduced the diversity of the fecal microbial population, and resulted in a higher expression of diseases, the environmental adaptation pathway, and the immune related pathway, whereas it lowered the expression of metabolic pathways (P < 0.05). High heat sensitive cows have upregulated metabolisms, environmental adaptation and cellular process pathways, and a downregulated neurodegenerative disease pathway (P < 0.05). Thus, we conclude that exposure to an HS environment modulates physiological characteristics, which may interplay with microbial activity, and in turn, alter the circulation levels of cytokines, implicating the role of the brain-gut axis in dairy cows. The HS environment affected physiological characteristics, cytokine levels, and microbial composition, but IH influenced RT and fecal microbial functions. PMID- 30279429 TI - Computerised Dynamic Posturography in Premanifest and Manifest individuals with Huntington's Disease. AB - Evidence from small-scale studies indicates that impairments in postural stability are an early and disabling feature of Huntington's disease (HD) and may be a useful clinical endpoint for disease modifying trials. Larger studies are needed to confirm these preliminary findings and the suitability of postural stability outcomes as clinical endpoints. Static and dynamic postural stability were evaluated in 54 premanifest HD, 36 manifest HD and 45 healthy individuals using the Sensory Organization Test (SOT) and Limits of Stability (LOS) test. Manifest HD displayed significantly lower scores on all SOT conditions and on the SOT composite score and had more falls than healthy and premanifest HD (p < 0.05). Premanifest and manifest HD demonstrated significantly lower endpoint excursion (p < 0.001), maximum excursion (p <= 0.001), and directional control (p <= 0.004) values than healthy individuals on the LOS test. Deficits in LOS were found to manifest on the left side of premanifest HD. Significant but low associations were observed between UHDRS-TMS, disease burden score, diagnostic confidence level, SOT conditions and SOT composite score. We confirm here that individuals with premanifest and manifest HD display significant impairments in static and dynamic postural stability. Dynamic posturography assessments should be considered as clinical endpoints for future disease modifying trials. PMID- 30279430 TI - A novel ulvan lyase family with broad-spectrum activity from the ulvan utilisation loci of Formosa agariphila KMM 3901. AB - Ulvan, which is one of the major structural polysaccharides of the cell walls of green macroalgae, is degraded by ulvan lyases via the beta-elimination mechanism with the release of oligosaccharides that have unsaturated 4-deoxy-L-threo-hex-4 enopyranosiduronic acid (?) at the non-reducing end. These ulvan lyases belong to the PL24 or PL25 or PL28 family in the CAZy database. In this study, we identify and biochemically characterise a periplasmic novel broad-spectrum ulvan lyase from Formosa agariphila KMM 3901. The lyase was overexpressed in Escherichia coli, and the purified recombinant enzyme depolymerised ulvan in an endolytic manner with a Km of 0.77 mg/ml, and displayed optimum activity at 40 degrees C and pH 8. This lyase also degraded heparan sulphate and chondroitin sulphate. Detailed analyses of the end-products of the enzymatic degradation of ulvan using 1H- and 13C-NMR and LC-MS revealed an unsaturated disaccharide (?Rha3S) and a tetrasaccharide (?Rha3S-Xyl-Rha) as the principal end-products. In contrast to the previously described ulvan lyases, this novel lyase is mostly composed of alpha-helices that form an (alpha/alpha)6 incomplete toroid domain and displays a remarkably broad-spectrum activity. This novel lyase is the first member of a new family of ulvan lyases. PMID- 30279431 TI - The role of scene summary statistics in object recognition. AB - Objects that are semantically related to the visual scene context are typically better recognized than unrelated objects. While context effects on object recognition are well studied, the question which particular visual information of an object's surroundings modulates its semantic processing is still unresolved. Typically, one would expect contextual influences to arise from high-level, semantic components of a scene but what if even low-level features could modulate object processing? Here, we generated seemingly meaningless textures of real world scenes, which preserved similar summary statistics but discarded spatial layout information. In Experiment 1, participants categorized such textures better than colour controls that lacked higher-order scene statistics while original scenes resulted in the highest performance. In Experiment 2, participants recognized briefly presented consistent objects on scenes significantly better than inconsistent objects, whereas on textures, consistent objects were recognized only slightly more accurately. In Experiment 3, we recorded event-related potentials and observed a pronounced mid-central negativity in the N300/N400 time windows for inconsistent relative to consistent objects on scenes. Critically, inconsistent objects on textures also triggered N300/N400 effects with a comparable time course, though less pronounced. Our results suggest that a scene's low-level features contribute to the effective processing of objects in complex real-world environments. PMID- 30279432 TI - 3D laser nano-printing on fibre paves the way for super-focusing of multimode laser radiation. AB - Multimode high-power laser diodes suffer from inefficient beam focusing, leading to a focal spot 10-100 times greater than the diffraction limit. This inevitably restricts their wider use in 'direct-diode' applications in materials processing and biomedical photonics. We report here a 'super-focusing' characteristic for laser diodes, where the exploitation of self-interference of modes enables a significant reduction of the focal spot size. This is achieved by employing a conical microlens fabricated on the tip of a multimode optical fibre using 3D laser nano-printing (also known as multi-photon lithography). When refracted by the conical surface, the modes of the fibre-coupled laser beam self-interfere and form an elongated narrow focus, usually referred to as a 'needle' beam. The multiphoton lithography technique allows the realisation of almost any optical element on a fibre tip, thus providing the most suitable interface for free-space applications of multimode fibre-delivered laser beams. In addition, we demonstrate the optical trapping of microscopic objects with a super-focused multimode laser diode beam thus rising new opportunities within the applications sector where lab-on-chip configurations can be exploited. Most importantly, the demonstrated super-focusing approach opens up new avenues for the 'direct-diode' applications in material processing and 3D printing, where both high power and tight focusing is required. PMID- 30279433 TI - Single shot femtosecond laser nano-ablation of CVD monolayer graphene. AB - We investigate ablation of CVD monolayer graphene by femtosecond pulses in the single shot regime. We show that the ablation probability of flat graphene drastically reduces for small illumination diameters even if the ablation threshold is exceeded. However, the presence of graphene wrinkles enhances the ablation probability. This is interpreted in terms of electron and energy diffusion within the graphene layer. This differentiated behavior is a drawback for single shot laser nanopatterning. The morphology of the holes with minimal diameter depends on the fluence distribution at ablation threshold. Strong fluence gradients due to strong focussing produce an explosive folding of graphene during ablation. PMID- 30279434 TI - Detection and characterization of traumatic bile leaks using Gd-EOB-DTPA enhanced magnetic resonance cholangiography. AB - Expanding bile leaks after blunt liver trauma require more aggressive treatment than contained bile leaks. In this retrospective study approved by institution review board, we analyzed if non-invasive contrast-enhanced magnetic resonance cholangiography (CEMRC) using hepatocyte-specific contrast agent (gadoxetic acid disodium) could detect and characterize traumatic bile leaks. Between March 2012 and December 2014, written informed consents from 22 included patients (17 men, 5 women) with a median age of 24.5 years (IQR 21.8, 36.0 years) were obtained. Biliary tree visualization and bile leak detection on CEMRC acquired at 10, 20, 30, 90 minutes time points were independently graded by three radiologists on a 5 point Likert scale. Intraclass Correlation (ICC) was computed as estimates of interrater reliability. Accuracy was measured by area under receiver operating characteristic curves (AUROC). Biliary tree visualization was the best on CEMRC at 90 minutes (score 4.30) with excellent inter-rater reliability (ICC = 0.930). Of 22 CEMRC, 15 had bile leak (8 expanding, 7 contained). The largest AUROC of bile leak detection by three radiologists were 0.824, 0.914, 0.929 respectively on CEMRC at 90 minutes with ICC of 0.816. In conclusion, bile leaks of blunt liver trauma can be accurately detected and characterized on CEMRC. PMID- 30279436 TI - Longitudinal analysis of biomarker data from a personalized nutrition platform in healthy subjects. AB - The trend toward personalized approaches to health and medicine has resulted in a need to collect high-dimensional datasets on individuals from a wide variety of populations, in order to generate customized intervention strategies. However, it is not always clear whether insights derived from studies in patient populations or in controlled trial settings are transferable to individuals in the general population. To address this issue, a longitudinal analysis was conducted on blood biomarker data from 1032 generally healthy individuals who used an automated, web based personalized nutrition and lifestyle platform. The study had two main aims: to analyze correlations between biomarkers for biological insights, and to characterize the effectiveness of the platform in improving biomarker levels. First, a biomarker correlation network was constructed to generate biological hypotheses that are relevant to researchers and, potentially, to users of personalized wellness tools. The correlation network revealed expected patterns, such as the established relationships between blood lipid levels, as well as novel insights, such as a connection between neutrophil and triglyceride concentrations that has been suggested as a relevant indicator of cardiovascular risk. Next, biomarker changes during platform use were assessed, showing a trend toward normalcy for most biomarkers in those participants whose values were out of the clinically normal range at baseline. Finally, associations were found between the selection of specific interventions and corresponding biomarker changes, suggesting directions for future study. PMID- 30279435 TI - Exposure to childhood abuse is associated with human sperm DNA methylation. AB - Offspring of persons exposed to childhood abuse are at higher risk of neurodevelopmental and physical health disparities across the life course. Animal experiments have indicated that paternal environmental stressors can affect sperm DNA methylation and gene expression in an offspring. Childhood abuse has been associated with epigenetic marks in human blood, saliva, and brain tissue, with statistically significant methylation differences ranging widely. However, no studies have examined the association of childhood abuse with DNA methylation in gametes. We examined the association of childhood abuse with DNA methylation in human sperm. Combined physical, emotional, and sexual abuse in childhood was characterized as none, medium, or high. DNA methylation was assayed in 46 sperm samples from 34 men in a longitudinal non-clinical cohort using HumanMethylation450 BeadChips. We performed principal component analysis and examined the correlation of principal components with abuse exposure. Childhood abuse was associated with a component that captured 6.2% of total variance in DNA methylation (p < 0.05). Next, we investigated the regions differentially methylated by abuse exposure. We identified 12 DNA regions differentially methylated by childhood abuse, containing 64 probes and including sites on genes associated with neuronal function (MAPT, CLU), fat cell regulation (PRDM16), and immune function (SDK1). We examined adulthood health behaviors, mental health, and trauma exposure as potential mediators of an association between abuse and DNAm, and found that mental health and trauma exposure partly mediated the association. Finally, we constructed a parsimonious epigenetic marker for childhood abuse using a machine learning approach, which identified three probes that predicted high vs. no childhood abuse in 71% of participants. Our results suggested that childhood abuse is associated with sperm DNA methylation, which may have implications for offspring development. Larger samples are needed to identify with greater confidence specific genomic regions differentially methylated by childhood abuse. PMID- 30279437 TI - Mesenchymal stem cells are attracted to latent HIV-1-infected cells and enable virus reactivation via a non-canonical PI3K-NFkappaB signaling pathway. AB - Persistence of latent HIV-1 in macrophages (MACs) and T-helper lymphocytes (THLs) remain a major therapeutic challenge. Currently available latency reversing agents (LRAs) are not very effective in vivo. Therefore, understanding of physiologic mechanisms that dictate HIV-1 latency/reactivation in reservoirs is clearly needed. Mesenchymal stromal/stem cells (MSCs) regulate the function of immune cells; however, their role in regulating virus production from latently infected MACs & THLs is not known. We documented that exposure to MSCs or their conditioned media (MSC-CM) rapidly increased HIV-1 p24 production from the latently-infected U1 (MAC) & ACH2 (THL) cell lines. Exposure to MSCs also increased HIV-1 long terminal repeat (LTR) directed gene expression in the MAC and THL reporter lines, U937-VRX and J-Lat (9.2), respectively. MSCs exposed to CM from U1 cells (U1-CM) showed enhanced migratory ability towards latently infected cells and retained their latency-reactivation potential. Molecular studies showed that MSC-mediated latency-reactivation was dependent upon both the phosphatidyl inositol-3-kinase (PI3K) and nuclear factor-kappaB (NFkappaB) signaling pathways. The pre-clinically tested inhibitors of PI3K (PX-866) and NFkappaB (CDDO-Me) suppressed MSC-mediated HIV-1 reactivation. Furthermore, coexposure to MSC-CM enhanced the latency-reactivation efficacy of the approved LRAs, vorinostat and panobinostat. Our findings on MSC-mediated latency reactivation may provide novel strategies against persistent HIV-1 reservoirs.

AB - Microbiome disruptions triggering disease outbreaks are increasingly threatening corals worldwide. In the Tropical Eastern Pacific, a necrotic-patch disease affecting gorgonian corals (sea fans, Pacifigorgia spp.) has been observed in recent years. However, the composition of the microbiome and its disease-related disruptions remain unknown in these gorgonian corals. Therefore, we analysed 16S rRNA gene amplicons from tissues of healthy colonies (n = 19) and from symptomatic-asymptomatic tissues of diseased colonies (n = 19) of Pacifigorgia cairnsi (Gorgoniidae: Octocorallia) in order to test for disease-related changes in the bacterial microbiome. We found that potential endosymbionts (mostly Endozoicomonas spp.) dominate the core microbiome in healthy colonies. Moreover, healthy tissues differed in community composition and functional profile from those of the symptomatic tissues but did not show differences to asymptomatic tissues of the diseased colonies. A more diverse set of bacteria was observed in symptomatic tissues, together with the decline in abundance of the potential endosymbionts from the healthy core microbiome. Furthermore, according to a comparative taxonomy-based functional profiling, these symptomatic tissues were characterized by the increase in heterotrophic, ammonia oxidizer and dehalogenating bacteria and by the depletion of nitrite and sulphate reducers. Overall, our results suggest that the bacterial microbiome associated with the disease behaves opportunistically and is likely in a state of microbial dysbiosis. We also conclude that the confinement of the disease-related consortium to symptomatic tissues may facilitate colony recovery. PMID- 30279440 TI - Primary rat LSECs preserve their characteristic phenotype after cryopreservation. AB - Liver disease is a leading cause of morbidity and mortality worldwide. Recently, the liver non-parenchymal cells have gained increasing attention for their potential role in the development of liver disease. Liver sinusoidal endothelial cells (LSECs), a specialized type of endothelial cells that have unique morphology and function, play a fundamental role in maintaining liver homeostasis. Current protocols for LSEC isolation and cultivation rely on freshly isolated cells which can only be maintained differentiated in culture for a few days. This creates a limitation in the use of LSECs for research and a need for a consistent and reliable source of these cells. To date, no LSEC cryopreservation protocols have been reported that enable LSECs to retain their functional and morphological characteristics upon thawing and culturing. Here, we report a protocol to cryopreserve rat LSECs that, upon thawing, maintain full LSEC signature features: fenestrations, scavenger receptor expression and endocytic function on par with freshly isolated cells. We have confirmed these features by a combination of biochemical and functional techniques, and super-resolution microscopy. Our findings offer a means to standardize research using LSECs, opening the prospects for designing pharmacological strategies for various liver diseases, and considering LSECs as a therapeutic target. PMID- 30279439 TI - Genetic conflicts with Plasmodium parasites and functional constraints shape the evolution of erythrocyte cytoskeletal proteins. AB - Plasmodium parasites exerted a strong selective pressure on primate genomes and mutations in genes encoding erythrocyte cytoskeleton proteins (ECP) determine protective effects against Plasmodium infection/pathogenesis. We thus hypothesized that ECP-encoding genes have evolved in response to Plasmodium driven selection. We analyzed the evolutionary history of 15 ECP-encoding genes in primates, as well as of their Plasmodium-encoded ligands (KAHRP, MESA and EMP3). Results indicated that EPB42, SLC4A1, and SPTA1 evolved under pervasive positive selection and that episodes of positive selection tended to occur more frequently in primate species that host a larger number of Plasmodium parasites. Conversely, several genes, including ANK1 and SPTB, displayed extensive signatures of purifying selection in primate phylogenies, Homininae lineages, and human populations, suggesting strong functional constraints. Analysis of Plasmodium genes indicated adaptive evolution in MESA and KAHRP; in the latter, different positively selected sites were located in the spectrin-binding domains. Because most of the positively selected sites in alpha-spectrin localized to the domains involved in the interaction with KAHRP, we suggest that the two proteins are engaged in an arms-race scenario. This observation is relevant because KAHRP is essential for the formation of "knobs", which represent a major virulence determinant for P. falciparum. PMID- 30279442 TI - Computational design of chemogenetic and optogenetic split proteins. AB - Controlling protein activity with chemogenetics and optogenetics has proven to be powerful for testing hypotheses regarding protein function in rapid biological processes. Controlling proteins by splitting them and then rescuing their activity through inducible reassembly offers great potential to control diverse protein activities. Building split proteins has been difficult due to spontaneous assembly, difficulty in identifying appropriate split sites, and inefficient induction of effective reassembly. Here we present an automated approach to design effective split proteins regulated by a ligand or by light (SPELL). We develop a scoring function together with an engineered domain to enable reassembly of protein halves with high efficiency and with reduced spontaneous assembly. We demonstrate SPELL by applying it to proteins of various shapes and sizes in living cells. The SPELL server (spell.dokhlab.org) offers an automated prediction of split sites. PMID- 30279441 TI - Hydrogen sulfide limits neutrophil transmigration, inflammation, and oxidative burst in lipopolysaccharide-induced acute lung injury. AB - Transmigration and activation of neutrophils in the lung reflect key steps in the progression of acute lung injury (ALI). It is known that hydrogen sulfide (H2S) can limit neutrophil activation, but the respective mechanisms remain elusive. Here, we aimed to examine the underlying pathways in pulmonary inflammation. In vivo, C57BL/6N mice received the H2S slow releasing compound GYY4137 prior to lipopolysaccharide (LPS) inhalation. LPS challenge led to pulmonary injury, inflammation, and neutrophil transmigration that were inhibited in response to H2S pretreatment. Moreover, H2S reduced mRNA expression of macrophage inflammatory protein-2 (MIP-2) and its receptor in lung tissue, as well as the accumulation of MIP-2 and interleukin-1beta in the alveolar space. In vitro, GYY4137 did not exert toxic effects on Hoxb8 neutrophils, but prevented their transmigration through an endothelial barrier in the presence and absence of MIP 2. In addition, the release of MIP-2 and reactive oxygen species from LPS stimulated Hoxb8 neutrophils were directly inhibited by H2S. Taken together, we provide first evidence that H2S limits lung neutrophil sequestration upon LPS challenge. As proposed underlying mechanisms, H2S prevents neutrophil transmigration through the inflamed endothelium and directly inhibits pro inflammatory as well as oxidative signalling in neutrophils. Subsequently, H2S pretreatment ameliorates LPS-induced ALI. PMID- 30279443 TI - Bridging of membrane surfaces by annexin A2. AB - The protein-mediated formation of membrane contacts is a crucial event in many cellular processes ranging from the establishment of organelle contacts to the docking of vesicles to a target membrane. Annexins are Ca2+ regulated membrane binding proteins implicated in providing such membrane contacts; however, the molecular basis of membrane bridging by annexins is not fully understood. We addressed this central question using annexin A2 (AnxA2) that functions in secretory vesicle exocytosis possibly by providing membrane bridges. By quantitatively analyzing membrane contact formation using a novel assay based on quartz crystal microbalance recordings, we show that monomeric AnxA2 can bridge membrane surfaces Ca2+ dependently. However, this activity depends on an oxidative crosslink involving a cysteine residue in the N-terminal domain and thus formation of disulfide-linked dimers. Alkylated AnxA2 in which this cysteine residue has been modified and AnxA2 mutants lacking the N-terminal domain are not capable of bridging membrane surfaces. In contrast, a heterotetrameric complex comprising two membrane binding AnxA2 subunits linked by a S100A10 dimer can provide membrane contacts irrespective of oxidation status. Thus, monomeric AnxA2 only contains one lipid binding site and AnxA2-mediated linking of membrane surfaces under non-oxidative intracellular conditions most likely requires AnxA2 S100 complex formation. PMID- 30279444 TI - Global patterns of change and variation in sea surface temperature and chlorophyll a. AB - Changes over the scale of decades in oceanic environments present a range of challenges for management and utilisation of ocean resources. Here we investigate sources of global temporal variation in Sea Surface Temperature (SST) and Ocean Colour (Chl-a) and their co-variation, over a 14 year period using statistical methodologies that partition sources of variation into inter-annual and annual components and explicitly account for daily auto-correlation. The variation in SST shows bands of increasing variability with increasing latitude, while the analysis of annual variability in Chl-a shows mostly mid-latitude high variability bands. Covariation patterns of SST and Chl-a suggests several different mechanisms impacting Chl-a change and variance. Our high spatial resolution analysis indicates these are likely to be operating at relatively small spatial scales. There are large regions showing warming and rising of Chl a, contrasting with regions that show warming and decreasing Chl-a. The covariation pattern in annual variation in SST and Chl-a reveals broad latitudinal bands. On smaller scales there are significant regional anomalies where upwellings are known to occur. Over decadal time scales both trend and variation in SST, Chl-a and their covariance is highly spatially heterogeneous, indicating that monitoring and resource management must be regionally appropriate. PMID- 30279445 TI - Molecular characterization and prospective isolation of human fetal cochlear hair cell progenitors. AB - Sensory hair cells located in the organ of Corti are essential for cochlear mechanosensation. Their loss is irreversible in humans resulting in permanent hearing loss. The development of therapeutic interventions for hearing loss requires fundamental knowledge about similarities and potential differences between animal models and human development as well as the establishment of human cell based-assays. Here we analyze gene and protein expression of the developing human inner ear in a temporal window spanning from week 8 to 12 post conception, when cochlear hair cells become specified. Utilizing surface markers for the cochlear prosensory domain, namely EPCAM and CD271, we purify postmitotic hair cell progenitors that, when placed in culture in three-dimensional organoids, regain proliferative potential and eventually differentiate to hair cell-like cells in vitro. These results provide a foundation for comparative studies with otic cells generated from human pluripotent stem cells and for establishing novel platforms for drug validation. PMID- 30279447 TI - Spatial Characterization of Soybean Yield and Quality (Amino Acids, Oil, and Protein) for United States. AB - Continued economic relevancy of soybean is a function of seed quality. The objectives of this study were to: (i) assess the spatial association between soybean yield and quality across major US soybean producing regions, (ii) investigate the relationship between protein, oil, and yield with amino acids (AAs) composition, and (iii) study interrelationship among essential AAs in soybean seed. Data from soybean testing programs conducted across 14 US states from 2012 to 2016 period (n = 35,101 data points) were analyzed. Results indicate that for each Mg ha-1 yield increase, protein yield increased by 0.35 Mg protein ha-1 and oil yield improved by 0.20 Mg oil ha-1. Essential AA concentrations exhibit a spatial autocorrelation and there was a negative relationship between concentration of AA, protein, and oil, with latitude. There was a positive interrelationship with different degree of strength among all AAs, and the correlation between Isoleucine and Valine was the strongest (r = 0.93) followed by the correlation among Arginine, Leucine, Lysine, and Threonine (0.71 < r < 0.88). We concluded that the variability in genotype (G) x management (M) x environment (E) across latitudes influencing yield also affected soybean quality; AA, protein, and oil content in a similar manner. PMID- 30279448 TI - Barriers to the evaluation of evidence-based public health policy. AB - Public health policy has the potential to produce great benefits for individuals and communities. There is growing demand that such efforts be rigorously evaluated to ensure that the expected benefits are, in fact, realised. Commonly, public health policy is evaluated by consumer acceptability, reach, or changes in knowledge and attitudes. Non-robust research designs are often used. But these approaches to evaluation do not answer three critical questions: Has a change in the desired outcome occurred? Was it a consequence of the policy and not some extraneous factor? Was the size of the change considered significant and cost effective? We, a team of government and academic scholars working in research and evaluation, have examined some of the more common impediments to robust evaluation: political impediments, a lack of investment in evaluation capacity within bureaucracy, and the failure of academic researchers to understand the need for the evaluation of public health policy. PMID- 30279446 TI - Total syntheses of shizukaols A and E. AB - Shizukaols possess a common heptacyclic framework containing more than ten contiguous stereocenters and potential biological activities. Here we report that the total syntheses of shizukaols A (1) and E (2), two lindenane-type dimers from the Chloranthaceae family, are achieved via a modified biomimetic Diels-Alder reaction. The common crucial biomimetic diene 23 and ethylene species (6, 17) are obtained through either a highly Z-selective olefination of alpha-siloxy ketone with ynolate anions or an intramolecular Horner-Wadsworth-Emmons olefination from commercially available Wieland-Miescher ketone (7). This synthetic approach here opens up practical avenues for the total syntheses of the intriguing Chloranthaceae family members, as well as the understanding of their relevant biological action in nature. PMID- 30279449 TI - A stably self-renewing adult blood-derived induced neural stem cell exhibiting patternability and epigenetic rejuvenation. AB - Recent reports suggest that induced neurons (iNs), but not induced pluripotent stem cell (iPSC)-derived neurons, largely preserve age-associated traits. Here, we report on the extent of preserved epigenetic and transcriptional aging signatures in directly converted induced neural stem cells (iNSCs). Employing restricted and integration-free expression of SOX2 and c-MYC, we generated a fully functional, bona fide NSC population from adult blood cells that remains highly responsive to regional patterning cues. Upon conversion, low passage iNSCs display a profound loss of age-related DNA methylation signatures, which further erode across extended passaging, thereby approximating the DNA methylation age of isogenic iPSC-derived neural precursors. This epigenetic rejuvenation is accompanied by a lack of age-associated transcriptional signatures and absence of cellular aging hallmarks. We find iNSCs to be competent for modeling pathological protein aggregation and for neurotransplantation, depicting blood-to-NSC conversion as a rapid alternative route for both disease modeling and neuroregeneration. PMID- 30279451 TI - Assembly of Schizosaccharomyces cryophilus chromosomes and their comparative genomic analyses revealed principles of genome evolution of the haploid fission yeasts. AB - The fission yeast clade, which has a distinct life history from other yeasts, can provide important clues about evolutionary changes. To reveal these changes the large S. cryophilus supercontigs were assembled into chromosomes using synteny relationships and the conserved pericentromeric, subtelomeric genes. Togetherness of the supercontigs was confirmed by PCR. Investigation of the gene order revealed localisation of the rDNA arrays, more than 300 new conserved orthologues and proved that S. cryophilus supercontigs were mosaics of collinear blocks. PFGE analysis showed that size of the S. cryophilus chromosomes differ from the S. pombe chromosomes. Comparative genomic analyses of the newly assembled chromosomes confirmed that the closest relative of S. cryophilus was S. octosporus not just in sequence similarity but also in a structural way, and revealed that preservation of the conserved regions did not arise from the lower number of chromosomal rearrangements. Translocations were more typical in the closely related species, while the number of inversions increased with the phylogenetic distances. Our data suggested that sites of the chromosomal rearrangements were not random and often associated with repetitive sequences, structural- and nucleotide evolution might correlate. Chromosomal rearrangements of the fission yeasts compared to other lineages were also discussed. PMID- 30279453 TI - From WCLC 2018. PMID- 30279452 TI - Risk factors of chronic kidney diseases in Chinese adults with type 2 diabetes. AB - In this study we conducted a cross sectional study to comprehensively evaluated the risk factors of chronic kidney disease (CKD) in a large sample of Chinese adults under primary care for type 2 diabetes mellitus (T2DM). We investigated the risk factors associated with the prevalence of CKD in adults with T2DM, who were enrolled in the Risk Factor Assessment and Management Programme for Patients with Diabetes Mellitus (RAMP-DM) of Hong Kong from July 2014 to June 2017. We collected the individual data of 31,574 subjects, with mean age of 63.0 (+/-10.8) years and mean DM duration of 7.4 (+/-6.4) years. Of them 9,386 (29.7%) had CKD and 7,452 (23.6%) had micro- or macro-albuminuria. After adjustment for multiple demographic and lifestyle confounders, we identified several modifiable risk factors associated with higher rate of CKD: obesity (OR = 1.54), current smoking (OR = 1.33), higher systolic blood pressure (OR = 1.01), dyslipidemia (OR = 1.32 and 0.61 for triglycerides (TG) and high-density lipoprotein cholesterol (HDL C)), hyperglycemia (OR = 1.11 for HbA1c), diabetic retinopathy (OR = 1.36 and 2.60 for non-sight and sight threatening retinopathy), and stroke (OR = 1.43). The risk factors of lower dialytic blood pressure and coronary heart disease were identified only in men, whereas peripheral arterial disease only in women. In conclusion, several modifiable and gender specific risk factors were significantly associated with higher prevalence of CKD in Chinese adults with T2DM. The high-risk populations identified in this study shall receive regular screening for renal functions to achieve better patient management in primary care settings. PMID- 30279450 TI - A systems-approach reveals human nestin is an endothelial-enriched, angiogenesis independent intermediate filament protein. AB - The intermediate filament protein nestin is expressed during embryonic development, but considered largely restricted to areas of regeneration in the adult. Here, we perform a body-wide transcriptome and protein-profiling analysis to reveal that nestin is constitutively, and highly-selectively, expressed in adult human endothelial cells (EC), independent of proliferative status. Correspondingly, we demonstrate that it is not a marker for tumour EC in multiple malignancy types. Imaging of EC from different vascular beds reveals nestin subcellular distribution is shear-modulated. siRNA inhibition of nestin increases EC proliferation, and nestin expression is reduced in atherosclerotic plaque neovessels. eQTL analysis reveals an association between SNPs linked to cardiovascular disease and reduced aortic EC nestin mRNA expression. Our study challenges the dogma that nestin is a marker of proliferation, and provides insight into its regulation and function in EC. Furthermore, our systems-based approach can be applied to investigate body-wide expression profiles of any candidate protein. PMID- 30279454 TI - A novel antimicrobial peptide acting via formyl peptide receptor 2 shows therapeutic effects against rheumatoid arthritis. AB - In oriental medicine, centipede Scolopendra subspinipes mutilans has long been used as a remedy for rheumatoid arthritis (RA), a well-known chronic autoimmune disorder. However, the molecular identities of its bioactive components have not yet been extensively investigated. We sought to identify bioactive molecules that control RA with a centipede. A novel antimicrobial peptide (AMP) (scolopendrasin IX) was identified from Scolopendra subspinipes mutilans. Scolopendrasin IX markedly activated mouse neutrophils, by enhancing cytosolic calcium increase, chemotactic cellular migration, and generation of superoxide anion in neutrophils. As a target receptor for scolopendrasin IX, formyl peptide receptor (FPR)2 mediates neutrophil activation induced by the AMP. Furthermore, scolopendrasin IX administration strongly blocked the clinical phenotype of RA in an autoantibody-injected model. Mechanistically, the novel AMP inhibited inflammatory cytokine synthesis from the joints and neutrophil recruitment into the joint area. Collectively, we suggest that scolopendrasin IX is a novel potential therapeutic agent for the control of RA via FPR2. PMID- 30279456 TI - SSRIs target prefrontal to raphe circuits during development modulating synaptic connectivity and emotional behavior. AB - Antidepressants that block the serotonin transporter, (Slc6a4/SERT), selective serotonin reuptake inhibitors (SSRIs) improve mood in adults but have paradoxical long-term effects when administered during perinatal periods, increasing the risk to develop anxiety and depression. The basis for this developmental effect is not known. Here, we show that during an early postnatal period in mice (P0-P10), Slc6a4/SERT is transiently expressed in a subset of layer 5-6 pyramidal neurons of the prefrontal cortex (PFC). PFC-SERT+ neurons establish glutamatergic synapses with subcortical targets, including the serotonin (5-HT) and GABA neurons of the dorsal raphe nucleus (DRN). PFC-to-DRN circuits develop postnatally, coinciding with the period of PFC Slc6a4/SERT expression. Complete or cortex-specific ablation of SERT increases the number of functional PFC glutamate synapses on both 5-HT and GABA neurons in the DRN. This PFC-to-DRN hyperinnervation is replicated by early-life exposure to the SSRI, fluoxetine (from P2 to P14), that also causes anxiety/depressive-like symptoms. We show that pharmacogenetic manipulation of PFC-SERT+ neuron activity bidirectionally modulates these symptoms, suggesting that PFC hypofunctionality has a causal role in these altered responses to stress. Overall, our data identify specific PFC descending circuits that are targets of antidepressant drugs during development. We demonstrate that developmental expression of SERT in this subset of PFC neurons controls synaptic maturation of PFC-to-DRN circuits, and that remodeling of these circuits in early life modulates behavioral responses to stress in adulthood. PMID- 30279455 TI - Predictors for a dementia gene mutation based on gene-panel next-generation sequencing of a large dementia referral series. AB - Next-generation genetic sequencing (NGS) technologies facilitate the screening of multiple genes linked to neurodegenerative dementia, but there are few reports about their use in clinical practice. Which patients would most profit from testing, and information on the likelihood of discovery of a causal variant in a clinical syndrome, are conspicuously absent from the literature, mostly for a lack of large-scale studies. We applied a validated NGS dementia panel to 3241 patients with dementia and healthy aged controls; 13,152 variants were classified by likelihood of pathogenicity. We identified 354 deleterious variants (DV, 12.6% of patients); 39 were novel DVs. Age at clinical onset, clinical syndrome and family history each strongly predict the likelihood of finding a DV, but healthcare setting and gender did not. DVs were frequently found in genes not usually associated with the clinical syndrome. Patients recruited from primary referral centres were compared with those seen at higher-level research centres and a national clinical neurogenetic laboratory; rates of discovery were comparable, making selection bias unlikely and the results generalisable to clinical practice. We estimated penetrance of DVs using large-scale online genomic population databases and found 71 with evidence of reduced penetrance. Two DVs in the same patient were found more frequently than expected. These data should provide a basis for more informed counselling and clinical decision making. PMID- 30279457 TI - Uncovering the complex genetics of human temperament. AB - Experimental studies of learning suggest that human temperament may depend on the molecular mechanisms for associative conditioning, which are highly conserved in animals. The main genetic pathways for associative conditioning are known in experimental animals, but have not been identified in prior genome-wide association studies (GWAS) of human temperament. We used a data-driven machine learning method for GWAS to uncover the complex genotypic-phenotypic networks and environmental interactions related to human temperament. In a discovery sample of 2149 healthy Finns, we identified sets of single-nucleotide polymorphisms (SNPs) that cluster within particular individuals (i.e., SNP sets) regardless of phenotype. Second, we identified 3 clusters of people with distinct temperament profiles measured by the Temperament and Character Inventory regardless of genotype. Third, we found 51 SNP sets that identified 736 gene loci and were significantly associated with temperament. The identified genes were enriched in pathways activated by associative conditioning in animals, including the ERK, PI3K, and PKC pathways. 74% of the identified genes were unique to a specific temperament profile. Environmental influences measured in childhood and adulthood had small but significant effects. We confirmed the replicability of the 51 Finnish SNP sets in healthy Korean (90%) and German samples (89%), as well as their associations with temperament. The identified SNPs explained nearly all the heritability expected in each sample (37-53%) despite variable cultures and environments. We conclude that human temperament is strongly influenced by more than 700 genes that modulate associative conditioning by molecular processes for synaptic plasticity and long-term memory. PMID- 30279458 TI - Connectomics of bipolar disorder: a critical review, and evidence for dynamic instabilities within interoceptive networks. AB - The notion that specific cognitive and emotional processes arise from functionally distinct brain regions has lately shifted toward a connectivity based approach that emphasizes the role of network-mediated integration across regions. The clinical neurosciences have likewise shifted from a predominantly lesion-based approach to a connectomic paradigm-framing disorders as diverse as stroke, schizophrenia (SCZ), and dementia as "dysconnection syndromes". Here we position bipolar disorder (BD) within this paradigm. We first summarise the disruptions in structural, functional and effective connectivity that have been documented in BD. Not surprisingly, these disturbances show a preferential impact on circuits that support emotional processes, cognitive control and executive functions. Those at high risk (HR) for BD also show patterns of connectivity that differ from both matched control populations and those with BD, and which may thus speak to neurobiological markers of both risk and resilience. We highlight research fields that aim to link brain network disturbances to the phenotype of BD, including the study of large-scale brain dynamics, the principles of network stability and control, and the study of interoception (the perception of physiological states). Together, these findings suggest that the affective dysregulation of BD arises from dynamic instabilities in interoceptive circuits which subsequently impact on fear circuitry and cognitive control systems. We describe the resulting disturbance as a "psychosis of interoception". PMID- 30279460 TI - Downregulation of autophagy by 12/15Lipoxygenase worsens the phenotype of an Alzheimer's disease mouse model with plaques, tangles, and memory impairments. AB - Among the different initiating events in Alzheimer's disease (AD) pathogenesis, oxidative stress and neuroinflammation are some of the most iimportant. In the central nervous system, the 12/15Lipoxygenase (12/15LO) enzyme is the source of potent pro-oxidants and inflammatory lipid mediators. Previous works showed that this pathway is up-regulated in AD brains and that its pharmacological targeting modulates the phenotype of transgenic mouse models of the disease. Here we investigate the effect of brain 12/15LO gene delivery on the AD-like phenotype of a mouse model with plaques, tangles and behavioral deficits, the 3xTg mice. Compared with controls, mice over-expressing 12/15LO manifested an exacerbation of spatial learning and memory impairments, which was associated with significant increase in Abeta formation and deposition, and accumulation of hyper phosphorylated insoluble tau secondary to a down-regulation of autophagy. In addition, the same mice manifested a worsening of neuroinflammation and synaptic pathology. Taken together our study supports the hypothesis that the 12/15LO enzymatic pathway by impairing neuronal autophagy plays a functional role in exacerbating AD-related neuropathologies and cognitive impairments. It provides further critical preclinical evidence to justify developing and testing new and selective 12/15LO inhibitors for AD treatment. PMID- 30279459 TI - Brain scans from 21,297 individuals reveal the genetic architecture of hippocampal subfield volumes. AB - The hippocampus is a heterogeneous structure, comprising histologically distinguishable subfields. These subfields are differentially involved in memory consolidation, spatial navigation and pattern separation, complex functions often impaired in individuals with brain disorders characterized by reduced hippocampal volume, including Alzheimer's disease (AD) and schizophrenia. Given the structural and functional heterogeneity of the hippocampal formation, we sought to characterize the subfields' genetic architecture. T1-weighted brain scans (n = 21,297, 16 cohorts) were processed with the hippocampal subfields algorithm in FreeSurfer v6.0. We ran a genome-wide association analysis on each subfield, co varying for whole hippocampal volume. We further calculated the single-nucleotide polymorphism (SNP)-based heritability of 12 subfields, as well as their genetic correlation with each other, with other structural brain features and with AD and schizophrenia. All outcome measures were corrected for age, sex and intracranial volume. We found 15 unique genome-wide significant loci across six subfields, of which eight had not been previously linked to the hippocampus. Top SNPs were mapped to genes associated with neuronal differentiation, locomotor behaviour, schizophrenia and AD. The volumes of all the subfields were estimated to be heritable (h2 from 0.14 to 0.27, all p < 1 * 10-16) and clustered together based on their genetic correlations compared with other structural brain features. There was also evidence of genetic overlap of subicular subfield volumes with schizophrenia. We conclude that hippocampal subfields have partly distinct genetic determinants associated with specific biological processes and traits. Taking into account this specificity may increase our understanding of hippocampal neurobiology and associated pathologies. PMID- 30279461 TI - Multisite de novo mutations in human offspring after paternal exposure to ionizing radiation. AB - A genome-wide evaluation of the effects of ionizing radiation on mutation induction in the mouse germline has identified multisite de novo mutations (MSDNs) as marker for previous exposure. Here we present the results of a small pilot study of whole genome sequencing in offspring of soldiers who served in radar units on weapon systems that were emitting high-frequency radiation. We found cases of exceptionally high MSDN rates as well as an increased mean in our cohort: While a MSDN mutation is detected in average in 1 out of 5 offspring of unexposed controls, we observed 12 MSDNs in altogether 18 offspring, including a family with 6 MSDNs in 3 offspring. Moreover, we found two translocations, also resulting from neighboring mutations. Our findings indicate that MSDNs might be suited in principle for the assessment of DNA damage from ionizing radiation also in humans. However, as exact person-related dose values in risk groups are usually not available, the interpretation of MSDNs in single families would benefit from larger molecular epidemiologic studies on this new biomarker. PMID- 30279462 TI - Development of multi-layered and multi-sensitive polymeric nanocontainers for cancer therapy: in vitro evaluation. AB - Nanoscale drug delivery systems represent a promising strategy to treat cancer and to overcome the side effects of chemotherapy. In particular, hollow polymeric nanocontainers have attracted great interest because of their structural and morphological advantages and the variety of polymers that can be used, allowing the synthesis of stimuli-responsive materials capable of responding to the biochemical alterations of the tumour microenvironment. Here are reported the synthesis, characterization and in vitro evaluation of a three-stimuli-sensitive hollow nanocontainer consisting of three different shells, each one sensitive to a specific tumoral stimulus: in order pH, temperature and reducing environment. To test its properties, daunorubicin was used as a model drug, for which the nanocontainers exhibited excellent encapsulation ability. The in vitro drug release behaviour was studied under different conditions, where the system proved capable of responding to the selected tumoral stimuli by releasing a larger amount of drug than in physiological environment. The hollow system itself showed negligible cytotoxicity but the loaded nanocontainers and free drug showed identical cytotoxicity and intracellular localization. Therefore, this formulation can be considered as a promising platform to develop an injectable delivery system capable of improving systematic toxicity without affecting or reducing the activity of the encapsulated drug. PMID- 30279463 TI - A High-Speed SSVEP-Based BCI Using Dry EEG Electrodes. AB - A high-speed steady-state visual evoked potentials (SSVEP)-based brain-computer interface (BCI) system using dry EEG electrodes was demonstrated in this study. The dry electrode was fabricated in our laboratory. It was designed as claw-like structure with a diameter of 14 mm, featuring 8 small fingers of 6 mm length and 2 mm diameter. The structure and elasticity can help the fingers pass through the hair and contact the scalp when the electrode is placed on head. The electrode was capable of recording spontaneous EEG and evoked brain activities such as SSVEP with high signal-to-noise ratio. This study implemented a twelve-class SSVEP-based BCI system with eight electrodes embedded in a headband. Subjects also completed a comfort level questionnaire with the dry electrodes. Using a preprocessing algorithm of filter bank analysis (FBA) and a classification algorithm based on task-related component analysis (TRCA), the average classification accuracy of eleven participants was 93.2% using 1-second-long SSVEPs, leading to an average information transfer rate (ITR) of 92.35 bits/min. All subjects did not report obvious discomfort with the dry electrodes. This result represented the highest communication speed in the dry-electrode based BCI systems. The proposed system could provide a comfortable user experience and a stable control method for developing practical BCIs. PMID- 30279464 TI - Tensorial neutron tomography of three-dimensional magnetic vector fields in bulk materials. AB - Knowing the distribution of a magnetic field in bulk materials is important for understanding basic phenomena and developing functional magnetic materials. Microscopic imaging techniques employing X-rays, light, electrons, or scanning probe methods have been used to quantify magnetic fields within planar thin magnetic films in 2D or magnetic vector fields within comparable thin volumes in 3D. Some years ago, neutron imaging has been demonstrated to be a unique tool to detect magnetic fields and magnetic domain structures within bulk materials. Here, we show how arbitrary magnetic vector fields within bulk materials can be visualized and quantified in 3D using a set of nine spin-polarized neutron imaging measurements and a novel tensorial multiplicative algebraic reconstruction technique (TMART). We first verify the method by measuring the known magnetic field of an electric coil and then investigate the unknown trapped magnetic flux within the type-I superconductor lead.

AB - The pace-of-life syndrome (POLS) hypothesis predicts variation in behaviour and physiology among individuals to be associated with variation in life history. Thus, individuals on the "fast" end of POLS continuum grow faster, exhibit higher metabolism, are more risk prone, but die earlier than ones on the "slow" end. Empirical support is nevertheless mixed and modelling studies suggested POLS to vary along selection gradients. Therefore, including ecological variation when testing POLS is vastly needed to determine whether POLS is a fixed construct or the result of specific selection processes. Here, we tested POLS predictions between and within two fish populations originating from different ecological conditions. We observed opposing life histories between populations, characterized by differential investments into growth, fecundity, and functional morphology under identical laboratory conditions. A slower life history was, on average, associated with boldness (latency to emergence from a refuge), high activity (short freezing time and long distance travelled), and increased standard metabolism. Correlation structures among POLS traits were not consistent between populations, with the expression of POLS observed in the slow-growing but not in the fast-growing population. Our results suggest that POLS traits can evolve independently from one another and that their coevolution depends upon specific ecological processes.

AB - OBJECTIVES: Current guidelines for necrotizing pancreatitis (NP) recommend delay in drainage +/- necrosectomy until 4 or more weeks after initial presentation to allow collections to wall off. However, evidence of infection with clinical deterioration despite maximum support may mandate earlier (<4 weeks) intervention. There are concerns, but scant data regarding risk of complications and outcomes with early endoscopic intervention. Our aim was to compare the results of an endoscopic centered step-up approach to NP when initiated before versus 4 or more weeks. METHODS: All patients undergoing intervention for NP were managed using an endoscopically centered step-up approach, with transluminal drainage whenever feasible, +/-necrosectomy, and/or percutaneous catheter drainage as needed, with surgery only for failures. Interventions were categorized as early or standard based on timing of intervention (<4 weeks or >= 4 weeks from onset of pancreatitis). Demographic data, indications and timing for interventions, number and type of intervention, mortality and morbidity (length of stay in hospital and ICU) and complications were compared. RESULTS: Of 305 patients with collections associated with NP, 193 (63%) (median age-52 years) required intervention, performed by a step-up approach. Of the 193 patients, 76 patients underwent early and 117 patients standard intervention. 144 (75%) interventions included endoscopic drainage +/- necrosectomy. As compared with standard intervention, early intervention was more often performed for infection (91% vs. 39%, p < 0.05), more associated with acute kidney injury (43% vs. 32%, p = 0.09), respiratory failure (41% vs. 22%, p = 0.005), and shock (13% vs. 4%, p < 0.05). Organ failure improved significantly after intervention in both groups. There was a significant difference in mortality (13% vs. 4%, p = 0.02) and need for rescue open necrosectomy (7% vs. 1%, p = 0.03) between groups. Patients undergoing early intervention had increased median hospital (37 days vs. 26 days, p = 0.01) and ICU stay (median 2.5 days vs. 0 days, p = 0.001). There was no difference in complications. CONCLUSIONS: When using an endoscopically centered step-up strategy in necrotizing pancreatitis, early (<4 weeks) interventions were more often performed for infection and organ failure, with no increase in complications, similar improvement in organ failure, slightly increased need for surgery, and relatively low mortality. Early endoscopic drainage +/- necrosectomy should be considered when there is a strong indication for intervention. PMID- 30279467 TI - Personalized response prediction. PMID- 30279468 TI - Lymphocyte activation gene 3 (Lag3) expression is increased in prion infections but does not modify disease progression. AB - Prion diseases, Alzheimer's disease and Parkinson's disease (PD) are fatal degenerative disorders that share common neuropathological and biochemical features, including the aggregation of pathological protein conformers. Lymphocyte activation gene 3 (Lag3, also known as CD223) is a member of the immunoglobulin superfamily of receptors expressed on peripheral immune cells, microglia and neurons, which serves as a receptor for alpha-synuclein aggregates in PD. Here we examined the possible role of Lag3 in the pathogenesis of prion diseases. Through quantitative real-time PCR and RNA-sequencing, we found that the expression levels of Lag3 were relatively low in the adult mouse brains, yet its expression was increased after prion infection. However, we failed finding significant differences regarding the incubation time, PrPSc load, neurodegeneration, astrocyte and microglia reactions and inflammatory gene expression between the Lag3 knockout mice and wild-type littermate controls after prion infection. We conclude that loss of Lag3 has no significant influence on prion disease pathogenesis. Considering that Lag3 is an immune checkpoint receptor, our results suggest that immune checkpoint inhibition (an increasingly prevalent therapeutic modality against many types of cancer) might not exert positive or negative effects on the progression of prion diseases. PMID- 30279469 TI - A hierarchical anti-Hebbian network model for the formation of spatial cells in three-dimensional space. AB - Three-dimensional (3D) spatial cells in the mammalian hippocampal formation are believed to support the existence of 3D cognitive maps. Modeling studies are crucial to comprehend the neural principles governing the formation of these maps, yet to date very few have addressed this topic in 3D space. Here we present a hierarchical network model for the formation of 3D spatial cells using anti Hebbian network. Built on empirical data, the model accounts for the natural emergence of 3D place, border, and grid cells, as well as a new type of previously undescribed spatial cell type which we call plane cells. It further explains the plausible reason behind the place and grid-cell anisotropic coding that has been observed in rodents and the potential discrepancy with the predicted periodic coding during 3D volumetric navigation. Lastly, it provides evidence for the importance of unsupervised learning rules in guiding the formation of higher-dimensional cognitive maps. PMID- 30279471 TI - Homozygosity mapping provides supporting evidence of pathogenicity in recessive Mendelian disease. AB - PURPOSE: One of the greatest challenges currently facing those studying Mendelian disease is identifying the pathogenic variant from the long list produced by a next-generation sequencing test. We investigate the predictive ability of homozygosity mapping for identifying the regions likely to contain the causative variant. METHODS: We use 179 homozygous pathogenic variants from three independent cohorts to investigate the predictive power of homozygosity mapping. RESULTS: We demonstrate that homozygous pathogenic variants in our cohorts are disproportionately likely to be found within one of the largest regions of homozygosity: 80% of pathogenic variants are found in a homozygous region that is in the ten largest regions in a sample. The maximal predictive power is achieved in patients with <8% homozygosity and variants >3 Mb from a telomere; this gives an area under the curve (AUC) of 0.735 and results in 92% of the causative variants being in one of the ten largest homozygous regions. CONCLUSION: This predictive power can be used to prioritize the list of candidate variants in gene discovery studies. When classifying a homozygous variant the size and rank of the region of homozygosity in which the candidate variant is located can also be considered as supporting evidence for pathogenicity. PMID- 30279472 TI - Mutations at the hydrophobic core affect Hal3 trimer stability, reducing its Ppz1 inhibitory capacity but not its PPCDC moonlighting function. AB - S. cerevisiae Hal3 (ScHal3) is a moonlighting protein that, is in its monomeric state, regulates the Ser/Thr protein phosphatase Ppz1, but also joins ScCab3 (and in some instances the Hal3 paralog Vhs3) to form an unusual heterotrimeric phosphopantothenoylcysteine decarboxylase (PPCDC) enzyme. PPCDC is required for CoA biosynthesis and in most eukaryotes is a homotrimeric complex with three identical catalytic sites at the trimer interfaces. However, in S. cerevisiae the heterotrimeric arrangement results in a single functional catalytic center. Importantly, the specific structural determinants that direct Hal3's oligomeric state and those required for Ppz1 inhibition remain largely unknown. We mutagenized residues in the predicted hydrophobic core of ScHal3 (L403-L405) and the plant Arabidopsis thaliana Hal3 (AtHal3, G115-L117) oligomers and characterized their properties as PPCDC components and, for ScHal3, also as Ppz1 inhibitor. We found that in AtHal3 these changes do not affect trimerization or PPCDC function. Similarly, mutation of ScHal3 L403 has no effect. In contrast, ScHal3 L405E fails to form homotrimers, but retains the capacity to bind Cab3 explaining its ability to rescue a hal3 vhs3 synthetically lethal mutation. Remarkably, the L405E mutation decreases Hal3's ability to interact with and to inhibit Ppz1, confirming the importance of the oligomer/monomer equilibrium in Hal3's Ppz1 regulating function.

PMID- 30279473 TI - Genomic assemblies of newly sequenced Trypanosoma cruzi strains reveal new genomic expansion and greater complexity. AB - Chagas disease is a complex illness caused by the protozoan Trypanosoma cruzi displaying highly diverse clinical outcomes. In this sense, the genome sequence elucidation and comparison between strains may lead to disease understanding. Here, two new T. cruzi strains, have been sequenced, Y using Illumina and Bug2148 using PacBio, assembled, analyzed and compared with the T. cruzi annotated genomes available to date. The assembly stats from the new sequences show effective improvement of T. cruzi genome over the actual ones. Such as, the largest contig assembled (1.3 Mb in Bug2148) in de novo attempts and the highest mean assembly coverage (71X for Y). Our analysis reveals a new genomic expansion and greater complexity for those multi-copy gene families related to infection process and disease development, such as Trans-sialidases, Mucins and Mucin Associated Surface Proteins, among others. On one side, we demonstrate that multi copy gene families are located near telomeric regions of the "chromosome-like" 1.3 Mb contig assembled of Bug2148, where they likely suffer high evolutive pressure. On the other hand, we identified several strain-specific single copy genes that might help to understand the differences in infectivity and physiology among strains. In summary, our results indicate that T. cruzi has a complex genomic architecture that may have promoted its evolution. PMID- 30279474 TI - Polystyrene microplastics increase microbial release of marine Chromophoric Dissolved Organic Matter in microcosm experiments. AB - About 5 trillion plastic particles are present in our oceans, from the macro to the micro size. Like any other aquatic particulate, plastics and microplastics can create a micro-environment, within which microbial and chemical conditions differ significantly from the surrounding water. Despite the high and increasing abundance of microplastics in the ocean, their influence on the transformation and composition of marine organic matter is largely unknown. Chromophoric dissolved organic matter (CDOM) is the photo-reactive fraction of the marine dissolved organic matter (DOM) pool. Changes in CDOM quality and quantity have impacts on marine microbial dynamics and the underwater light environment. One major source of CDOM is produced by marine bacteria through their alteration of pre-existing DOM substrates. In a series of microcosm experiments in controlled marine conditions, we explored the impact of microplastics on the quality and quantity of microbial CDOM. In the presence of microplastics we observed an increased production of CDOM with changes in its molecular weight, which resulted from either an increased microbial CDOM production or an enhanced transformation of DOM from lower to higher molecular weight CDOM. Our results point to the possibility that marine microplastics act as localized hot spots for microbial activity, with the potential to influence marine carbon dynamics. PMID- 30279475 TI - Dysregulation of the endothelin pathway in lymphangioleiomyomatosis with no direct effect on cell proliferation and migration. AB - LAM is a rare low-grade metastasizing lung neoplasm. Inhibitors of mTOR improve clinical outcome of LAM patients by preventing loss of lung function. Nevertheless, other cell targets may be of interest for drug development. Therefore, we explored the potential role of EDN1 (endothelin) in LAM. We report an increased endothelin blood level in LAM patients as well as EDN1 overexpression and EDN1 receptor downregulation in LAM-derived primary cells and in TSC2NEG cells mutated in TSC2. We evidenced EDN pathway dysregulation based on EDN1, EDNRA, EDNRB and ARRB1 mRNA expression in LAM-derived primary cells. We showed overexpression of EDN1 and ARRB1 mRNAs in TSC2NEG cells; these cells lost their ability to respond to stimulation by endothelin. We analyzed the effects of endothelin receptor antagonists alone or in combination with rapamycin, an mTOR inhibitor, on proliferation and migration of LAM cells. Rapamycin treatment of TSC2NEG cells significantly reduced cell proliferation or migration, while none of the tested inhibitors of EDN receptors impaired these functions. We showed that TSC2NEG cells have acquired a transformed phenotype as showed by their ability to grow as spheroids in semi-solid medium and that unlike endothelin receptors antagonists, rapamycin reduced anchorage-independent cell growth and prevented expansion of TSC2NEG spheroids. PMID- 30279476 TI - Riemerella anatipestifer AS87_RS09170 gene is responsible for biotin synthesis, bacterial morphology and virulence. AB - Riemerella anatipestifer is a bacterial pathogen responsible for major economic losses within the duck industry. Recent studies have revealed that biotin biosynthesis is critical for the bacterium's survival and virulence. We previously found that R. anatipestifer AS87_RS09170, a putative bioF gene, is important for bacterial virulence. In the present study, we characterized the AS87_RS09170 gene in R. anatipestifer strain Yb2. Sequence analysis indicated that the AS87_RS09170 gene is highly conserved among R. anatipestifer strains; the deduced protein harbored the conserved pyridoxal 5'-phosphate binding pocket of 8-amino-7-oxononanoate synthase. Western blot analysis demonstrated that the biotin-dependent enzyme was present in smaller quantities in the mutant strain Yb2DeltabioF compared to that of the wide-type strain Yb2, suggesting that the biotin biosynthesis was defective. The mutant strain Yb2DeltabioF displayed a decreased growth rate at the exponential phase in tryptic soy broth culture and in BeaverBeads Streptavidin treated tryptic soy broth culture, but recovered when biotin was supplemented. In addition, the mutant strain Yb2DeltabioF showed an enhanced biofilm formation, as well as increased adhesion and invasion capacities to duck embryo fibroblasts. Moreover, the mutant strain Yb2DeltabioF exhibited irregular shapes with budding vegetations and relatively thickened cell walls under scanning and transmission electron microscope observation, as well as a reduced capacity to establish systemic infection in a duck infection model. These results provide the first evidence that the R. anatipestifer AS87_RS09170 gene is responsible for biotin synthesis, bacterial morphology and virulence. PMID- 30279477 TI - Additive Manufactured and Topology Optimized Passive Shimming Elements for Permanent Magnetic Systems. AB - A method to create a highly homogeneous magnetic field by applying topology optimized, additively manufactured passive shimming elements is investigated. The topology optimization algorithm can calculate a suitable permanent and nonlinear soft magnetic design that fulfills the desired field properties. The permanent magnetic particles are bonded in a polyamide matrix and they are manufactured with a low-cost, end-user 3D printer. Stray field measurements and an inverse stray field simulation framework can determine printing and magnetization errors. The customized shimming elements are manufactured by a selective melting process which produces completely dense soft magnetic metal parts. The methodology is demonstrated on a simple example of two axial symmetric cylindrical magnets, which generates a high inhomogeneous magnetic field. In this case, the maximum magnetic field density is 25 mT and the the homogeneity can be increased by a factor of 35 or down to 60/00. Simulation and measurement results point out a good conformity. Additional topology optimizations of more than one shimming element layer show the opportunity to make the manufactured magnetic system even more homogeneous. PMID- 30279478 TI - Cationic domains in particle-forming and assembly-deficient HBV core antigens capture mammalian RNA that stimulates Th1-biased antibody responses by DNA vaccination. AB - The HBV core protein self-assembles into particles and encapsidates immune stimulatory bacterial RNA through a cationic COOH-terminal (C150-183) domain. To investigate if different cationic domains have an impact on the endogenous RNA binding of HBV-C antigens in mammalian cells, we developed a strep-tag (st) based expression/purification system for HBV-C/RNA antigens in vector-transfected HEK 293 cells. We showed that HBV-stC but not HBV-stC149 particles (lacking the cationic domain) capture low amounts of mammalian RNA. Prevention of specific phosphorylation in cationic domains, either by exchanging the serine residues S155, S162 and S170 with alanines (HBV-stCAAA) or by exchanging the entire cationic domain with a HIV-tat48-57-like sequence (HBV-stC149tat) enhanced the encapsidation of RNA into mutant core particles. Particle-bound mammalian RNA functioned as TLR-7 ligand and induced a Th1-biased humoral immunity in B6 but not in TLR-7-/- mice by exogenous (protein) and endogenous (DNA) vaccines. Compared to core particles, binding of mammalian RNA to freely exposed cationic domains in assembly-deficient antigens was enhanced. However, RNA bound to non particulate antigens unleash its Th1-stimulating adjuvant activity by DNA- but not protein-based vaccination. Mammalian RNAs targeted by an endogenously expressed antigen thus function as a natural adjuvant in the host that facilitates priming of Th1-biased immune responses by DNA-based immunization. PMID- 30279479 TI - Vibrational control of selective bond cleavage in dissociative chemisorption of methanol on Cu(111). AB - Controlling product branching ratios in a chemical reaction represents a desired but difficult achievement in chemistry. In this work, we demonstrate the first example of altering the branching ratios in a multichannel reaction, i.e., methanol dissociative chemisorption on Cu(111), via selectively exciting specific vibrational modes. To this end, we develop a globally accurate full-dimensional potential energy surface for the CH3OH/Cu(111) system and perform extensive vibrational state-selected molecular dynamics simulations. Our results show that O-H/C-H/C-O stretching vibrational excitations substantially enhance the respective bond scission processes, representing extraordinary bond selectivity. At a given total energy, the branching ratio of C-O/C-H dissociation can increase by as large as 100 times by exciting the C-O stretching mode which possesses an unprecedentedly strong vibrational efficacy on reactivity. This vibrational control can be realized by the well-designed experiment using a linearly polarized laser. PMID- 30279481 TI - Fast neural learning in dogs: A multimodal sensory fMRI study. AB - Dogs may follow their nose, but they learn associations to many types of sensory stimuli. Are some modalities learned better than others? We used awake fMRI in 19 dogs over a series of three experiments to measure reward-related learning of visual, olfactory, and verbal stimuli. Neurobiological learning curves were generated for individual dogs by measuring activation over time within three regions of interest: the caudate nucleus, amygdala, and parietotemporal cortex. The learning curves showed that dogs formed stimulus-reward associations in as little as 22 trials. Consistent with neuroimaging studies of associative learning, the caudate showed a main effect for reward-related stimuli, but not a significant interaction with modality. However, there were significant differences in the time courses, suggesting that although multiple modalities are represented in the caudate, the rates of acquisition and habituation are modality dependent and are potentially gated by their salience in the amygdala. Visual and olfactory modalities resulted in the fastest learning, while verbal stimuli were least effective, suggesting that verbal commands may be the least efficient way to train dogs. PMID- 30279480 TI - Arc/Arg3.1 has an activity-regulated interaction with PICK1 that results in altered spatial dynamics. AB - Activity-regulated cytoskeleton-associated protein (Arc; also known as Arg3.1) is an immediate early gene product that is transcribed in dendritic spines and, to date, has been best characterized as a positive regulator of AMPAR endocytosis during long-term depression (LTD) through interaction with endocytic proteins. Here, we show that protein interacting with C terminal kinase 1 (PICK1), a protein known to bind to the GluA2 subunit of AMPARs and associated with AMPAR trafficking, was pulled-down from brain homogenates and synaptosomes when using Arc as immobilized bait. Fluctuation and FLIM-FRET-Phasor analysis revealed direct interaction between these proteins when co-expressed that was increased under depolarizing conditions in live cells. At the plasma membrane, Arc-mCherry oligomerization was found to be concentration dependent. Additionally, co expression of Arc-mCherry and EGFP-PICK1 followed by depolarizing conditions resulted in significant increases in the number and size of puncta containing both proteins. Furthermore, we identified the Arc binding region to be the first 126 amino acids of the PICK1 BAR domain. Overall, our data support a novel interaction and model where PICK1 mediates Arc regulation of AMPARs particularly under depolarizing conditions. PMID- 30279482 TI - Histone deacetylase (HDAC) 1 and 2 complexes regulate both histone acetylation and crotonylation in vivo. AB - Proteomic analysis of histones has shown that they are subject to a superabundance of acylations, which extend far beyond acetylation, to include: crotonylation, propionylation, butyrylation, malonylation, succinylation, beta hydroxybutyrylation and 2-hydroxyisobutyrylation. To date, much of the functional data has focussed on histone crotonylation which, similar to acetylation, has been associated with positive gene regulation and is added by the acyltransferase, p300. Although Sirtuins 1-3, along with HDAC3, have been shown to possess decrotonylase activity in vitro, there is relatively little known about the regulation of histone crotonylation in vivo. Here we show that Histone Deacetylase 1 and 2 (HDAC1/2), the catalytic core of numerous co-repressor complexes, are important histone decrotonylase enzymes. A ternary complex of HDAC1/CoREST1/LSD1 is able to hydrolyse both histone H3 Lys18-acetyl (H3K18ac) and H3 Lys18-crotonyl (H3K18cr) peptide substrates. Genetic deletion of HDAC1/2 in ES cells increases global levels of histone crotonylation and causes an 85% reduction in total decrotonylase activity. Furthermore, we mapped H3K18cr in cells using ChIP-seq, with and without HDAC1/2, and observed increased levels of crotonylation, which largely overlaps with H3K18ac in the vicinity of transcriptional start sites. Collectively, our data indicate that HDAC1/2 containing complexes are critical regulators of histone crotonylation in vivo. PMID- 30279483 TI - Angiogenic Properties of 'Leukocyte- and Platelet-Rich Fibrin'. AB - Leukocyte- and Platelet-Rich Fibrin (L-PRF) is an autologous platelet concentrate, consisting of a fibrin matrix enriched with platelets, leukocytes and a plethora of cytokines and growth factors. Since L-PRF is produced bedside from whole blood without the use of an anti-coagulant, it is becoming a popular adjuvant in regenerative medicine. While other types of platelet concentrates have been described to stimulate blood vessel formation, little is known about the angiogenic capacities of L-PRF. Therefore, this study aimed to fully characterize the angiogenic potential of L-PRF. With an antibody array, the growth factors released by L-PRF were determined and high levels of CXC chemokine receptor 2 (CXCR-2) ligands and epidermal growth factor (EGF) were found. L-PRF induced in vitro key steps of the angiogenic process: endothelial proliferation, migration and tube formation. In addition, we could clearly demonstrate that L PRF is able to induce blood vessel formation in vivo, the chorioallantoic membrane assay. In conclusion, we could demonstrate the angiogenic capacity of L PRF both in vitro and in vivo, underlying the clinical potential of this easy-to use platelet concentrate. PMID- 30279484 TI - Drug screening of biopsy-derived spheroids using a self-generated microfluidic concentration gradient. AB - Performing drug screening of tissue derived from cancer patient biopsies using physiologically relevant 3D tumour models presents challenges due to the limited amount of available cell material. Here, we present a microfluidic platform that enables drug screening of cancer cell-enriched multicellular spheroids derived from tumour biopsies, allowing extensive anticancer compound screening prior to treatment. This technology was validated using cell lines and then used to screen primary human prostate cancer cells, grown in 3D as a heterogeneous culture from biopsy-derived tissue. The technology enabled the formation of repeatable drug concentration gradients across an array of spheroids without external fluid actuation, delivering simultaneously a range of drug concentrations to multiple sized spheroids, as well as replicates for each concentration. As proof-of concept screening, spheroids were generated from two patient biopsies and a panel of standard-of-care compounds for prostate cancer were tested. Brightfield and fluorescence images were analysed to provide readouts of spheroid growth and health, as well as drug efficacy over time. Overall, this technology could prove a useful tool for personalised medicine and future drug development, with the potential to provide cost- and time-reduction in the healthcare delivery. PMID- 30279486 TI - A systems biology approach to explore the impact of maple tree dormancy release on sap variation and maple syrup quality. AB - Maple sap is a complex nutrient matrix collected during spring to produce maple syrup. The characteristics of sap change over the production period and its composition directly impacts syrup quality. This variability could in part be attributed to changes in tree metabolism following dormancy release, but little is known about these changes in deciduous trees. Therefore, understanding the variation in sap composition associated with dormancy release could help pinpoint the causes of some defects in maple syrup. In particular, a defect known as "buddy", is an increasing concern for the industry. This off-flavor appears around the time of bud break, hence its name. To investigate sap variation related to bud break and the buddy defect, we monitored sap variation with respect to a dormancy release index (Sbb) and syrup quality. First, we looked at variation in amino acid content during this period. We observed a shift in amino acid relative proportions associated with dormancy release and found that most of them increase rapidly near the point of bud break, correlating with changes in syrup quality. Second, we identified biological processes that respond to variation in maple sap by performing a competition assay using the barcoded Saccharomyces cerevisiae prototroph deletion collection. This untargeted approach revealed that the organic sulfur content may be responsible for the development of the buddy off-flavor, and that dormancy release is necessary for the appearance of the defect, but other factors such as microbial activity may also be contributing. PMID- 30279485 TI - RIP2 filament formation is required for NOD2 dependent NF-kappaB signalling. AB - Activation of the innate immune pattern recognition receptor NOD2 by the bacterial muramyl-dipeptide peptidoglycan fragment triggers recruitment of the downstream adaptor kinase RIP2, eventually leading to NF-kappaB activation and proinflammatory cytokine production. Here we show that full-length RIP2 can form long filaments mediated by its caspase recruitment domain (CARD), in common with other innate immune adaptor proteins. We further show that the NOD2 tandem CARDs bind to one end of the RIP2 CARD filament, suggesting a mechanism for polar filament nucleation by activated NOD2. We combine X-ray crystallography, solid state NMR and high-resolution cryo-electron microscopy to determine the atomic structure of the helical RIP2 CARD filament, which reveals the intermolecular interactions that stabilize the assembly. Using structure-guided mutagenesis, we demonstrate the importance of RIP2 polymerization for the activation of NF-kappaB signalling by NOD2. Our results could be of use to develop new pharmacological strategies to treat inflammatory diseases characterised by aberrant NOD2 signalling. PMID- 30279487 TI - Discovery of Novel Soluble Epoxide Hydrolase Inhibitors as Potent Vasodilators. AB - In view of the role of sEH (soluble epoxide hydrolase) in hypertension, we have developed a rigorously validated pharmacophore model containing one HBA (Hydrogen Bond Acceptor), two HY (Hydrophobic) and one RA (Ring Aromatic) features. The model was used as a query to search the NCI (National Cancer Institute) and Maybridge database leading to retrieval of many compounds which were sorted on the basis of predicted activity, fit value and Lipinski's violation. The selected compounds were docked into the active site of enzyme soluble epoxide hydrolase. Potential interactions were observed between the features of the identified hits and the amino acids present in the docking site. The three selected compounds were subjected to in vitro evaluation using enzyme- based assay and the isolated rat aortic model followed by cytotoxicity studies. The results demonstrate that the identified compounds are potent, safe and novel soluble epoxide hydrolase inhibitors. PMID- 30279488 TI - A phage-based assay for the rapid, quantitative, and single CFU visualization of E. coli (ECOR #13) in drinking water. AB - Drinking water standards in the United States mandate a zero tolerance of generic E. coli in 100 mL of water. The presence of E. coli in drinking water indicates that favorable environmental conditions exist that could have resulted in pathogen contamination. Therefore, the rapid and specific enumeration of E. coli in contaminated drinking water is critical to mitigate significant risks to public health. To meet this challenge, we developed a bacteriophage-based membrane filtration assay that employs novel fusion reporter enzymes to fully quantify E. coli in less than half the time required for traditional enrichment assays. A luciferase and an alkaline phosphatase, both specifically engineered for increased enzymatic activity, were selected as reporter probes due to their strong signal, small size, and low background. The genes for the reporter enzymes were fused to genes for carbohydrate binding modules specific to cellulose. These constructs were then inserted into the E. coli-specific phage T7 which were used to infect E. coli trapped on a cellulose filter. During the infection, the reporters were expressed and released from the bacterial cells following the lytic infection cycle. The binding modules facilitated the immobilization of the reporter probes on the cellulose filter in proximity to the lysed cells. Following substrate addition, the location and quantification of E. coli cells could then be determined visually or using bioluminescence imaging for the alkaline phosphatase and luciferase reporters, respectively. As a result, a detection assay capable of quantitatively detecting E. coli in drinking water with similar results to established methods, but less than half the assay time was developed. PMID- 30279489 TI - Paradoxical positive association of serum adiponectin with all-cause mortality based on body composition in Japanese haemodialysis patients. AB - We have previously reported a paradoxical association of serum adiponectin with aortic calcification in haemodialysis patients. Because serum adiponectin is a nutritional marker, we examined the association between serum adiponectin and all cause mortality based on body composition in haemodialysis patients. The trunk and total body fat were determined. The patients were divided into two groups based on serum adiponectin levels. In Kaplan-Meier analysis, the higher adiponectin group showed higher mortality than the lower adiponectin group. Serum adiponectin showed an inverse correlation with the percentage of truncal fat, suggesting serum adiponectin as an inverse marker for adiposity in haemodialysis patients. However, even after adjustment for other factors, multivariate Cox proportional hazards analysis identified higher serum adiponectin as an independent factor positively associated with higher mortality in haemodialysis patients. This association held true even when the total fat mass was replaced with the percentage of truncal fat, and when total fat mass and percentage of truncal fat were simultaneously included. Thus, we found a paradoxical association of higher serum adiponectin with higher all-cause mortality in Japanese haemodialysis patients, independent of adiposity. PMID- 30279490 TI - Tailoring manganese oxide with atomic precision to increase surface site availability for oxygen reduction catalysis. AB - Controlling the structure of catalysts at the atomic level provides an opportunity to establish detailed understanding of the catalytic form-to-function and realize new, non-equilibrium catalytic structures. Here, advanced thin-film deposition is used to control the atomic structure of La2/3Sr1/3MnO3, a well known catalyst for the oxygen reduction reaction. The surface and sub-surface is customized, whereas the overall composition and d-electron configuration of the oxide is kept constant. Although the addition of SrMnO3 benefits the oxygen reduction reaction via electronic structure and conductivity improvements, SrMnO3 can react with ambient air to reduce the surface site availability. Placing SrMnO3 in the sub-surface underneath a LaMnO3 overlayer allows the catalyst to maintain the surface site availability while benefiting from improved electronic effects. The results show the promise of advanced thin-film deposition for realizing atomically precise catalysts, in which the surface and sub-surface structure and stoichiometry are tailored for functionality, over controlling only bulk compositions. PMID- 30279491 TI - Hyperglycaemia-induced methylglyoxal accumulation potentiates VEGF resistance of diabetic monocytes through the aberrant activation of tyrosine phosphatase SHP 2/SRC kinase signalling axis. AB - Diabetes mellitus (DM) is a major cardiovascular risk factor contributing to cardiovascular complications by inducing vascular cell dysfunction. Monocyte dysfunction could contribute to impaired arteriogenesis response in DM patients. DM monocytes show blunted chemotactic responses to arteriogenic stimuli, a condition termed as vascular endothelial growth factor (VEGF) resistance. We hypothesize that methylglyoxal (MG), a glucose metabolite, induces monocyte dysfunction and aimed to elucidate the underlying molecular mechanisms. Human monocytes exposed to MG or monocytes from DM patients or mice (db/db) showed VEGF resistance secondary to a pro-migratory phenotype. Mechanistically, DM conditions or MG exposure resulted in the upregulation of the expression of SHP-2 phosphatase. This led to the enhanced activity of SHP-2 and aided an interaction with SRC kinase. SHP-2 dephosphorylated the inhibitory phosphorylation site of SRC leading to its abnormal activation and phosphorylation of cytoskeletal protein, paxillin. We demonstrated that MG-induced molecular changes could be reversed by pharmacological inhibitors of SHP-2 and SRC and by genetic depletion of SHP-2. Finally, a SHP-2 inhibitor completely reversed the dysfunction of monocytes isolated from DM patients and db/db mice. In conclusion, we identified SHP-2 as a hitherto unknown target for improving monocyte function in diabetes. This opens novel perspectives for treating diabetic complications associated with impaired monocyte function. PMID- 30279494 TI - The Role of p53 in Determining Mitochondrial Adaptations to Endurance Training in Skeletal Muscle. AB - p53 plays an important role in regulating mitochondrial homeostasis. However, it is unknown whether p53 is required for the physiological and mitochondrial adaptations with exercise training. Furthermore, it is also unknown whether impairments in the absence of p53 are a result of its loss in skeletal muscle, or a secondary effect due to its deletion in alternative tissues. Thus, we investigated the role of p53 in regulating mitochondria both basally, and under the influence of exercise, by subjecting C57Bl/6J whole-body (WB) and muscle specific p53 knockout (mKO) mice to a 6-week training program. Our results confirm that p53 is important for regulating mitochondrial content and function, as well as proteins within the autophagy and apoptosis pathways. Despite an increased proportion of phosphorylated p53 (Ser15) in the mitochondria, p53 is not required for training-induced adaptations in exercise capacity or mitochondrial content and function. In comparing mouse models, similar directional alterations were observed in basal and exercise-induced signaling modifications in WB and mKO mice, however the magnitude of change was less pronounced in the mKO mice. Our data suggest that p53 is required for basal mitochondrial maintenance in skeletal muscle, but is not required for the adaptive responses to exercise training. PMID- 30279493 TI - Correcting glucose-6-phosphate dehydrogenase deficiency with a small-molecule activator. AB - Glucose-6-phosphate dehydrogenase (G6PD) deficiency, one of the most common human genetic enzymopathies, is caused by over 160 different point mutations and contributes to the severity of many acute and chronic diseases associated with oxidative stress, including hemolytic anemia and bilirubin-induced neurological damage particularly in newborns. As no medications are available to treat G6PD deficiency, here we seek to identify a small molecule that corrects it. Crystallographic study and mutagenesis analysis identify the structural and functional defect of one common mutant (Canton, R459L). Using high-throughput screening, we subsequently identify AG1, a small molecule that increases the activity of the wild-type, the Canton mutant and several other common G6PD mutants. AG1 reduces oxidative stress in cells and zebrafish. Furthermore, AG1 decreases chloroquine- or diamide-induced oxidative stress in human erythrocytes. Our study suggests that a pharmacological agent, of which AG1 may be a lead, will likely alleviate the challenges associated with G6PD deficiency.

AB - Understanding the viability of the ischemic myocardial tissue is a critical issue in determining the appropriate surgical procedure for patients with chronic heart failure after myocardial infarction (MI). Conventional MI evaluation methods are; however, preoperatively performed and/or give an indirect information of myocardial viability such as shape, color, and blood flow. In this study, we realize the evaluation of MI in patients undergoing cardiac surgery by Raman spectroscopy under label-free conditions, which is based on intrinsic molecular constituents related to myocardial viability. We identify key signatures of Raman spectra for the evaluation of myocardial viability by evaluating the infarct border zone myocardium that were excised from five patients under surgical ventricular restoration. We also obtain a prediction model to differentiate the infarcted myocardium from the non-infarcted myocardium by applying partial least squares regression-discriminant analysis (PLS-DA) to the Raman spectra. Our prediction model enables identification of the infarcted tissues and the non infarcted tissues with sensitivities of 99.98% and 99.92%, respectively. Furthermore, the prediction model of the Raman images of the infarct border zone enabled us to visualize boundaries between these distinct regions. Our novel application of Raman spectroscopy to the human heart would be a useful means for the detection of myocardial viability during surgery. PMID- 30279498 TI - Advanced sulfide solid electrolyte by core-shell structural design. AB - Solid electrolyte is critical to next-generation solid-state lithium-ion batteries with high energy density and improved safety. Sulfide solid electrolytes show some unique properties, such as the high ionic conductivity and low mechanical stiffness. Here we show that the electrochemical stability window of sulfide electrolytes can be improved by controlling synthesis parameters and the consequent core-shell microstructural compositions. This results in a stability window of 0.7-3.1 V and quasi-stability window of up to 5 V for Li-Si-P S sulfide electrolytes with high Si composition in the shell, a window much larger than the previously predicted one of 1.7-2.1 V. Theoretical and computational work explains this improved voltage window in terms of volume constriction, which resists the decomposition accompanying expansion of the solid electrolyte. It is shown that in the limiting case of a core-shell morphology that imposes a constant volume constraint on the electrolyte, the stability window can be further opened up. Advanced strategies to design the next generation sulfide solid electrolytes are also discussed based on our understanding. PMID- 30279497 TI - Zebra finches identify individuals using vocal signatures unique to each call type. AB - Individual recognition is critical in social animal communication, but it has not been demonstrated for a complete vocal repertoire. Deciphering the nature of individual signatures across call types is necessary to understand how animals solve the problem of combining, in the same signal, information about identity and behavioral state. We show that distinct signatures differentiate zebra finch individuals for each call type. The distinctiveness of these signatures varies: contact calls bear strong individual signatures while calls used during aggressive encounters are less individualized. We propose that the costly solution of using multiple signatures evolved because of the limitations of the passive filtering properties of the birds' vocal organ for generating sufficiently individualized features. Thus, individual recognition requires the memorization of multiple signatures for the entire repertoire of conspecifics of interests. We show that zebra finches excel at these tasks. PMID- 30279492 TI - Megahertz serial crystallography. AB - The new European X-ray Free-Electron Laser is the first X-ray free-electron laser capable of delivering X-ray pulses with a megahertz inter-pulse spacing, more than four orders of magnitude higher than previously possible. However, to date, it has been unclear whether it would indeed be possible to measure high-quality diffraction data at megahertz pulse repetition rates. Here, we show that high quality structures can indeed be obtained using currently available operating conditions at the European XFEL. We present two complete data sets, one from the well-known model system lysozyme and the other from a so far unknown complex of a beta-lactamase from K. pneumoniae involved in antibiotic resistance. This result opens up megahertz serial femtosecond crystallography (SFX) as a tool for reliable structure determination, substrate screening and the efficient measurement of the evolution and dynamics of molecular structures using megahertz repetition rate pulses available at this new class of X-ray laser source. PMID- 30279499 TI - Lower extremity joint-level responses to pelvis perturbation during human walking. AB - The human leg joints play a major role in balance control during walking. They facilitate leg swing, and modulate the ground (re)action forces to prevent a fall. The aim of this study is to provide and explore data on perturbed human walking to gain a better understanding of balance recovery during walking through joint-level control. Healthy walking subjects randomly received anteroposterior and mediolateral pelvis perturbations at the instance of toe-off. The open-source modeling tool OpenSim was used to perform inverse kinematics and inverse dynamics analysis. We found hip joint involvement in accelerating and then halting leg swing, suggesting active preparation for foot placement. Additionally, responses in the stance leg's ankle and hip joints contribute to balance recovery by decreasing the body's velocity in the perturbation direction. Modulation also occurs in the plane perpendicular to the perturbation direction, to safeguard balance in both planes. Finally, the recorded muscle activity suggests both spinal and supra-spinal mediated contributions to balance recovery, scaling with perturbation magnitude and direction. The presented data provide a unique and multi-joint insight in the complexity of both frontal and sagittal plane balance control during human walking in terms of joint angles, moments, and power, as well as muscle EMG responses. PMID- 30279500 TI - The Chemokine CCL3 Regulates Myeloid Differentiation and Hematopoietic Stem Cell Numbers. AB - The chemokine CCL3 is frequently overexpressed in malignancies and overexpression leads to microenvironmental dysfunction. In murine models of chronic myelogenous leukemia (CML), CCL3 is critical for the maintenance of a leukemia stem cell population, and leukemia progression. With CCL3 implicated as a potentially viable therapeutic target, it is important to carefully characterize its role in normal hematopoietic homeostasis. CCL3-/- mice were used to evaluate the role of CCL3 in regulating hematopoietic stem and progenitor cell (HSPC) populations. CCL3-/- mice had loss of mature myeloid populations, while myeloid progenitors and HSPCs were increased, and microenvironmental populations were unchanged. These data show that CCL3 promotes myeloid lineage differentiation and the size of the HSPC pool independent of the supportive bone marrow microenvironment. Our results demonstrate a previously unrecognized role of CCL3 in the maintenance of homeostatic hematopoiesis that should be evaluated when targeting CCL3 signaling for the treatment of hematologic malignancy. PMID- 30279502 TI - Sin3A recruits Tet1 to the PAH1 domain via a highly conserved Sin3-Interaction Domain. AB - The Sin3A complex acts as a transcriptional hub, integrating the function of diverse transcription factors with histone modifying enzymes, notably, histone deacetylases (HDAC) 1 and 2. The Sin3A protein sits at the centre of the complex, mediating multiple simultaneous protein-protein interactions via its four paired amphipathic helix (PAH) domains (PAH1-4). The PAH domains contain a conserved four helical bundle, generating a hydrophobic cleft into which the single-helix of a Sin3-interaction domain (SID) is able to insert and bind with high affinity. Although they share a similar mode of interaction, the SIDs of different repressor proteins bind to only one of four potential PAH domains, due to the specific combination of hydrophobic residues at the interface. Here we report the identification of a highly conserved SID in the 5-methylcytosine dioxygenase, Tet1 (Tet1-SID), which interacts directly with the PAH1 domain of Sin3A. Using a combination of NMR spectroscopy and homology modelling we present a model of the PAH1/Tet1-SID complex, which binds in a Type-II orientation similar to Sap25. Mutagenesis of key residues show that the 11-amino acid Tet1-SID is necessary and sufficient for the interaction with Sin3A and is absolutely required for Tet1 to repress transcription in cells.

PMID- 30279501 TI - Cell cycle-resolved chromatin proteomics reveals the extent of mitotic preservation of the genomic regulatory landscape. AB - Regulation of transcription, replication, and cell division relies on differential protein binding to DNA and chromatin, yet it is unclear which regulatory components remain bound to compacted mitotic chromosomes. By utilizing the buoyant density of DNA-protein complexes after cross-linking, we here develop a mass spectrometry-based approach to quantify the chromatin-associated proteome at separate stages of the cell cycle. While epigenetic modifiers that promote transcription are lost from mitotic chromatin, repressive modifiers generally remain associated. Furthermore, while proteins involved in transcriptional elongation are evicted, most identified transcription factors are retained on mitotic chromatin to varying degrees, including core promoter binding proteins. This predicts conservation of the regulatory landscape on mitotic chromosomes, which we confirm by genome-wide measurements of chromatin accessibility. In summary, this work establishes an approach to study chromatin, provides a comprehensive catalog of chromatin changes during the cell cycle, and reveals the degree to which the genomic regulatory landscape is maintained through mitosis. PMID- 30279504 TI - Metabolic Alterations Associated with Atorvastatin/Fenofibric Acid Combination in Patients with Atherogenic Dyslipidaemia: A Randomized Trial for Comparison with Escalated-Dose Atorvastatin. AB - In the current study, the metabolic effects of atorvastatin dose escalation versus atorvastatin/fenofibric acid combination were compared using metabolomics analyses. Men and women with combined hyperlipidaemia were initially prescribed atorvastatin (10 mg, >=4 weeks). Patients who reached low-density lipoprotein cholesterol targets, but had triglyceride and high-density lipoprotein cholesterol levels >=150 mg/dL and <50 mg/dL, respectively, were randomized to receive atorvastatin 20 mg or atorvastatin 10 mg/fenofibric acid 135 mg for 12 weeks. Metabolite profiling of serum was performed and changes in metabolites after drug treatment in the two groups were compared. Analysis was performed using patients' samples obtained before and after treatment. Of 89 screened patients, 37 who met the inclusion criteria were randomized, and 34 completed the study. Unlike that in the dose-escalation group, distinct clustering of both lipid and aqueous metabolites was observed in the combination group after treatment. Most lipid metabolites of acylglycerols and many of ceramides decreased, while many of sphingomyelins increased in the combination group. Atorvastatin dose escalation modestly decreased lysophosphatidylcholines; however, the effect of combination therapy was variable. Most aqueous metabolites decreased, while L-carnitine remarkably increased in the combination group. In conclusion, the atorvastatin/fenofibric acid combination induced distinct metabolite clustering. Our results provide comprehensive information regarding metabolic changes beyond conventional lipid profiles for this combination therapy. PMID- 30279505 TI - Defects, Dopants and Sodium Mobility in Na2MnSiO4. AB - Sodium manganese orthosilicate, Na2MnSiO4, is a promising positive electrode material in rechargeable sodium ion batteries. Atomistic scale simulations are used to study the defects, doping behaviour and sodium migration paths in Na2MnSiO4. The most favourable intrinsic defect type is the cation anti-site (0.44 eV/defect), in which, Na and Mn exchange their positions. The second most favourable defect energy process is found to be the Na Frenkel (1.60 eV/defect) indicating that Na diffusion is assisted by the formation of Na vacancies via the vacancy mechanism. Long range sodium paths via vacancy mechanism were constructed and it is confirmed that the lowest activation energy (0.81 eV) migration path is three dimensional with zig-zag pattern. Subvalent doping by Al on the Si site is energetically favourable suggesting that this defect engineering stratergy to increase the Na content in Na2MnSiO4 warrants experimental verification. PMID- 30279506 TI - Renoprotective effect of Zhenwu decoction against renal fibrosis by regulation of oxidative damage and energy metabolism disorder. AB - Zhenwu decoction (ZWD) is a promising traditional Chinese prescription against renal fibrosis, while its underlying mechanism remains unclear. Rat model of renal fibrosis were established and divided into control group, model group, ZWD treatment group and enalapril maleate treatment group. Metabolic profiles on serum samples from each group were acquired by using ultra performance liquid chromatography coupled with quadrupole time-of-flight high-resolution mass spectrometry. Metabolomics combined with molecular biology were comparatively conducted on samples of various groups. Fifteen potential biomarkers were identified and these biomarkers are mainly phospholipids and fatty acids. The results showed renal fibrosis was associated with oxidative damage and energy metabolism disorder. The results of histopathology, biochemistry and metabolomics demonstrated that ZWD exhibited an efficient renoprotective effect by alleviating oxidative stress, increasing energy metabolism and regulating fibrotic cytokines. This study provided scientific support for the research and development of new drugs from traditional Chinese medicine. PMID- 30279507 TI - Single Dose Administration of Taheebo Polyphenol Enhances Endurance Capacity in Mice. AB - Endurance capacity is important for maintenance of quality of life as well as performance of endurance athletes. In order to improve endurance, intake of nutritional supplements as well as exercise training is also important. Indeed, polyphenolic extracts from plants are known to improve endurance capacity via increase of fatty acid utilization, mitochondrial biogenesis or inhibition of oxidative stress. Taheebo, the extract obtained from inner bark of Tabebuia avellanedae has been reported to have beneficial effects for treatment of inflammation, oxidative stress and obesity. Here, we investigated the effects and mechanisms of polyphenol fraction of taheebo (taheebo polyphenol; TP) on endurance capacity of mice. Single dose administration of TP significantly increased running time until exhaustion. Acute TP administration increased blood glucose and muscle glycogen levels (p < 0.05) through alteration on expression level of genes involved with glycogen metabolism and gluconeogenesis. Furthermore, TP administration decreased exercise-induced increase of protein carbonyls in skeletal muscle. These results suggest that TP administration improve endurance capacity via up-regulation of skeletal muscle glycogen levels and maintenance of blood glucose by acceleration of gluconeogenesis as well as inhibition of exercise-induced oxidative stress. Single administration of TP also increased phosphorylation of AMP-activated protein kinase (AMPK) and gene expression level of sirtuin 1 (SIRT1) but did not change the marker of mitochondrial biogenesis. PMID- 30279508 TI - Locally-curved geometry generates bending cracks in the African elephant skin. AB - An intricate network of crevices adorns the skin surface of the African bush elephant, Loxodonta africana. These micrometre-wide channels enhance the effectiveness of thermal regulation (by water retention) as well as protection against parasites and intense solar radiation (by mud adherence). While the adaptive value of these structures is well established, their morphological characterisation and generative mechanism are unknown. Using microscopy, computed tomography and a custom physics-based lattice model, we show that African elephant skin channels are fractures of the animal brittle and desquamation deficient skin outermost layer. We suggest that the progressive thickening of the hyperkeratinised stratum corneum causes its fracture due to local bending mechanical stress in the troughs of a lattice of skin millimetric elevations. The African elephant skin channels are therefore generated by thickening of a brittle material on a locally-curved substrate rather than by a canonical tensile cracking process caused by frustrated shrinkage. PMID- 30279510 TI - The mapping of cancer incidence and mortality trends in the UK from 1980-2013 reveals a potential for overdiagnosis. AB - The incidence of cancer in the United Kingdom has increased significantly over the last four decades. The aim of this study was to examine trends in UK cancer incidence and mortality by cancer site and assess the potential for overdiagnosis. Using Cancer Research UK incidence and mortality data for the period (1971-2014) we estimated percentage change in incidence and mortality rates and the incidence-mortality ratio (IMR) for cancers in which incidence had increased >50%. Incidence and mortality trend plots were used to assess the potential for overdiagnosis. Incidence rates increased from 67% (uterine) to 375% (melanoma). Change in mortality rates ranged from -69% (cervical) to +239% (liver). The greatest divergences occurred in uterine (IMR = 132), prostate (IMR = 9.6), oral (IMR = 9.8) and thyroid cancer (IMR = 5.3). Only in liver cancer did mortality track incidence (IMR = 1.1). For four cancer sites; uterine, prostate, oral and thyroid, incidence and mortality trends are suggestive of overdiagnosis. Trends in melanoma and kidney cancer suggest potential overdiagnosis and an underlying increase in true risk, whereas for cervical and breast cancer, trends may also reflect improvements in treatments or earlier diagnosis. A more detailed analysis is required to fully understand these patterns. PMID- 30279511 TI - Airway epithelial cells prime plasmacytoid dendritic cells to respond to pathogens via secretion of growth factors. AB - Plasmacytoid dendritic cells (PDCs) are critical for defense against respiratory viruses because of their propensity to secrete high levels of type I interferons (IFN). The functions of PDCs in the lung can be influenced by airway epithelial cells. We examined the effect of human primary bronchial epithelial cells (PBECs) on PDC functions by performing RNA-sequencing of PDCs after co-culture with air liquid interface differentiated PBECs. Functional analysis revealed that PDCs co cultured with PBECs displayed upregulation of type I IFN production and response genes. Upregulated transcripts included those encoding cytosolic sensors of DNA, ZBP-1,IRF-3, and NFkB as well as genes involved in amplification of the IFN response, such as IFNAR1, JAK/STAT, ISG15. In keeping with the RNA-seq data, we observe increased secretion of type I IFN and other cytokines in response to influenza in PDCs co-cultured with PBECs. The PDCs also primed Th1 responses in T cells. The enhanced response of PDCs co-cultured with PBECs was due to the action of growth factors, GMCSF, GCSF, and VEGF, which were secreted by PBECs on differentiation. These data highlight possible mechanisms to enhance the production of type-I IFN in the airways, which is critical for host defense against respiratory infections. PMID- 30279509 TI - Functional equivalence of genome sequencing analysis pipelines enables harmonized variant calling across human genetics projects. AB - Hundreds of thousands of human whole genome sequencing (WGS) datasets will be generated over the next few years. These data are more valuable in aggregate: joint analysis of genomes from many sources increases sample size and statistical power. A central challenge for joint analysis is that different WGS data processing pipelines cause substantial differences in variant calling in combined datasets, necessitating computationally expensive reprocessing. This approach is no longer tenable given the scale of current studies and data volumes. Here, we define WGS data processing standards that allow different groups to produce functionally equivalent (FE) results, yet still innovate on data processing pipelines. We present initial FE pipelines developed at five genome centers and show that they yield similar variant calling results and produce significantly less variability than sequencing replicates. This work alleviates a key technical bottleneck for genome aggregation and helps lay the foundation for community-wide human genetics studies. PMID- 30279512 TI - A dendritic cell-based systemic vaccine induces long-lived lung-resident memory Th17 cells and ameliorates pulmonary mycosis. AB - Tissue-resident memory T cells (TRMs) are a novel nonvascular memory T cell subset. Although CD8+ TRMs are well-characterized, CD4+ TRMs-especially lung resident memory Th17 cells-are still being defined. In this study, we characterized lung-resident memory Th17 cells (lung TRM17) and their role in protection against the highly virulent fungus Cryptococcus gattii. We found that intravenously transferred DCs preferentially migrated to lungs and attracted recipient DCs and led to the induction of long-lived Th17 cells expressing characteristic markers. This population could be clearly discriminated from circulating T cells by intravascular staining and was not depleted by the immunosuppressive agent FTY720. The C. gattii antigen re-stimulation assay revealed that vaccine-induced lung Th17 cells produced IL-17A but not IFNgamma. The DC vaccine significantly increased IL-17A production and suppressed fungal burden in the lungs and improved the survival of mice infected with C. gattii. This protective effect was significantly reduced in the IL-17A knockout (KO) mice, but not in the FTY720-treated mice. The protective effect also coincided with the activation of neutrophils and multinucleated giant cells, and these inflammatory responses were suppressed in the vaccinated IL-17A KO mice. Overall, these data demonstrated that the systemic DC vaccine induced lung TRM17, which played a substantial role in anti-fungal immunity. PMID- 30279514 TI - NLRC4 suppresses IL-17A-mediated neutrophil-dependent host defense through upregulation of IL-18 and induction of necroptosis during Gram-positive pneumonia. AB - Gram-positive pathogens, including Staphylococcus aureus, cause necrotizing pneumonia. The central feature of S. aureus pneumonia is toxin-induced necroptosis of immune and resident cells, which impedes host defense. However, the role of the NLRC4 in the lung following S. aureus infection remains elusive. Here, we demonstrate that S. aureus activates the NLRC4 to drive necroptosis and IL-18 production, which impaired IL-17A-dependent neutrophil-mediated host susceptibility. In particular, Nlrc4-/- mice exhibit reduced necroptosis, enhanced neutrophil influx into the lungs, decreased bacterial burden, and improved host survival. Loss of NLRC4 signaling in both hematopoietic and non hematopoietic cells contributes to the host protection against S. aureus pneumonia. Secretion of IL-17A by gammadelta T cells is essential for neutrophil recruitment into the lungs of Nlrc4-/- mice following infection. Moreover, treatment of wild-type mice with necroptosis inhibitors or genetic ablation of MLKL and IL-18 improves host defense against S. aureus infection, which is associated with increased IL-17A+gammadelta T cells and neutrophils. Taken together, these novel findings reveal that S. aureus activates the NLRC4 to dampen IL-17A-dependent neutrophil accumulation through induction of necroptosis and IL-18. Thus, modulating the function of the NLRC4 may be an attractive therapeutic approach for treating S. aureus infections. PMID- 30279513 TI - Resolvin D1 treatment on goblet cell mucin and immune responses in the chronic allergic eye disease (AED) model. AB - Severe, chronic eye allergy is an understudied, vision-threatening condition. Treatments remain limited. We used a mouse model of severe allergic eye disease (AED) to determine whether topical application of the pro-resolution mediator Resolvin D1 (RvD1) terminates the response. AED was induced by injection of ovalbumin (OVA) followed by topical challenge of OVA daily. RvD1 was applied topically prior to OVA. Clinical symptoms were scored. Eye washes were assayed for MUC5AC. After 7 days, eyes were removed and the number of goblet cells, T helper cell responses and presence of immune cells in draining lymph nodes and conjunctiva determined. Topical RvD1 treatment significantly reduced symptoms of AED. RvD1 did not alter the systemic type 2 immune response in the lymph nodes. AED increased the total amount of goblet cell mucin secretion, but not the number of goblet cells. RvD1 prevented this increase, but did not alter goblet cell number. Absolute numbers of CD4 + T cells, total CD11b + myeloid cells, eosinophils, neutrophils, and monocytes, but not macrophages increased in AED versus RvD1-treated mice. We conclude that topical application of RvD1 reduced the ocular allergic response by local actions in conjunctival immune response and a decrease in goblet cell mucin secretion. PMID- 30279515 TI - CLA-supplemented diet accelerates experimental colorectal cancer by inducing TGF beta-producing macrophages and T cells. AB - Conjugated linoleic acid (CLA) has been shown to activate the nuclear receptor PPAR-gamma and modulate metabolic and immune functions. Despite the worldwide use of CLA dietary supplementation, strong scientific evidence for its proposed beneficial actions are missing. We found that CLA-supplemented diet reduced mucosal damage and inflammatory infiltrate in the dextran sodium sulfate (DSS) induced colitis model. Conditional deletion of PPAR-gamma in macrophages from mice supplemented with CLA diet resulted in loss of this protective effect of CLA, suggesting a PPAR-gamma-dependent mechanism mediated by macrophages. However, CLA supplementation significantly worsened colorectal tumor formation induced by azoxymethane and DSS by inducing macrophage and T-cell-producing TGF beta via PPAR-gamma activation. Accordingly, either macrophage-specific deletion of PPAR-gamma or in vivo neutralization of latency-associated peptide (LAP, a membrane-bound TGF-beta)-expressing cells abrogated the protumorigenic effect of CLA. Thus, the anti-inflammatory properties of CLA are associated with prevention of colitis but also with development of colorectal cancer. PMID- 30279516 TI - NOX1-derived ROS drive the expression of Lipocalin-2 in colonic epithelial cells in inflammatory conditions. AB - Inflammatory bowel disease (IBD) is characterized by severe and recurrent inflammation of the gastrointestinal tract, associated with altered patterns of cytokine synthesis, excessive reactive oxygen species (ROS) production, and high levels of the innate immune protein, lipocalin-2 (LCN-2), in the mucosa. The major source of ROS in intestinal epithelial cells is the NADPH oxidase NOX1, which consists of the transmembrane proteins, NOX1 and p22PHOX, and the cytosolic proteins, NOXO1, NOXA1, and Rac1. Here, we investigated whether NOX1 activation and ROS production induced by key inflammatory cytokines in IBD causally affects LCN-2 production in colonic epithelial cells. We found that the combination of TNFalpha and IL-17 induced a dramatic upregulation of NOXO1 expression that was dependent on the activation of p38MAPK and JNK1/2, and resulted into an increase of NOX1 activity and ROS production. NOX1-derived ROS drive the expression of LCN 2 by controlling the expression of IkappaBzeta, a master inducer of LCN-2. Furthermore, LCN-2 production and colon damage were decreased in NOX1-deficient mice during TNBS-induced colitis. Finally, analyses of biopsies from patients with Crohn's disease showed increased JNK1/2 activation, and NOXO1 and LCN-2 expression. Therefore, NOX1 might play a key role in mucosal immunity and inflammation by controlling LCN-2 expression. PMID- 30279517 TI - Succinate receptor mediates intestinal inflammation and fibrosis. AB - Succinate, an intermediate of the tricarboxylic acid cycle, is accumulated in inflamed areas and its signaling through succinate receptor (SUCNR1) regulates immune function. We analyze SUCNR1 expression in the intestine of Crohn's disease patients and its role in murine intestinal inflammation and fibrosis. We show that both serum and intestinal succinate levels and SUCNR1 expression in intestinal surgical resections were higher in CD patients than in controls. SUCNR1 co-localized with CD86, CD206, and alpha-SMA+ cells in human intestine and we found a positive and significant correlation between SUCNR1 and alpha-SMA expression. In human isolated fibroblasts from CD patients SUCNR1 expression was higher than in those from controls and treatment with succinate increased SUCNR1 expression, fibrotic markers and inflammatory cytokines through SUCNR1. This receptor modulated the expression of pro-inflammatory cytokines in resting murine macrophages, macrophage polarization and fibroblast activation and Sucnr1-/- mice were protected against both acute TNBS-colitis and intestinal fibrosis induced by the heterotopic transplant of colonic tissue. We demonstrate increased succinate levels in serum and SUCNR1 expression in intestinal tissue of CD patients and show a role for SUCNR1 in murine intestinal inflammation and fibrosis. PMID- 30279518 TI - Non-toxigenic Bacteroides fragilis (NTBF) administration reduces bacteria-driven chronic colitis and tumor development independent of polysaccharide A. AB - Polysaccharide A (PSA), an immunogenic capsular component of non-toxigenic Bacteroides fragilis (NTBF) strain NCTC 9343, is reported to promote mucosal immune development and suppress colitis. Contrastingly, enterotoxigenic Bacteroides fragilis (ETBF) is highly associated with inflammatory bowel disease (IBD) and colorectal cancer (CRC), rapidly inducing IL-17-dependent murine colitis and tumorigenesis. In specific-pathogen-free (SPF) C57BL/6 wild-type (WT) and multiple intestinal neoplasia (MinApc716+/-) mice, we show that sequential treatment of the NTBF strain, 9343, followed by the ETBF strain, 86-5443-2-2 (86), diminished colitis and tumorigenesis. Mice treated simultaneously with 9343 and 86 exhibited both severe colitis and tumorigenesis. Abrogated disease severity in sequentially treated mice was attributed to 9343 strain dominance and decreased IL-17A, but 86 colonization prior to or simultaneous with 9343 mitigated the anti-inflammatory effect of 9343. Remarkably, 9343-mediated protection was independent of PSA, as sequentially treated mice receiving DeltaPSA 9343 exhibited similar protection. Further, SPF WT and Min mice colonized with PSA-competent or PSA-deficient 9343 exhibited similar IL-10, IL 17, and IFN-gamma responses. Treatment of 86-colonized mice with 9343 failed to disrupt 86 pathogenesis. Our findings demonstrate that 9343 colonization, independent of PSA, offers prophylaxis against colitis-inducing 86 but may not be a valid therapy once colitis is established. PMID- 30279519 TI - Diagnostic value of plasma tryptophan and symmetric dimethylarginine levels for acute kidney injury among tacrolimus-treated kidney transplant patients by targeted metabolomics analysis. AB - Few literatures have evaluated the exact role of metabolomics in the identification process of potential biomarkers for acute kidney injury among the patients receiving renal transplantation. On top of this, the success of metabolomics in biomarker translation seems to lie in the robust quantitative method. As such, a single-center retrospective observational study was conducted enrolling 42 patients underwent renal transplantation with/without acute kidney injury, as well as 24 healthy volunteers, in Shanghai Changzheng Hospital. Plasma amino acid metabolic patterns for the participants were investigated by targeted UHPLC-MS/MS metabolic profiling. The most significant changes of the explored metabolites were related to the disturbance of tryptophan metabolism and arginine metabolism. Abnormal circulating tryptophan and symmetric dimethylarginine were identified to be potential biomarkers of acute kidney injury, combination of which showed a higher area under receiver-operator curve value (AUC = 0.901), improved sensitivity (0.889) and specificity (0.831) compared with creatinine only. Overall, these results revealed that targeted metabolomics analysis would be a potent and promising strategy for identification and pre-validation of biomarkers of acute kidney injury in renal transplantation patients.

AB - The Kuroshio transports warm water in the Pacific poleward from the tropics and plays a crucial role in modulating surrounding climate. Based on independent data sets, we demonstrated that the Kuroshio weakened downstream east of Taiwan, but intensified upstream east of Luzon Island during 1993-2013. The surface velocity (volume transport) of the Kuroshio has decreased 12.5% (4~5%) off east Taiwan but increased 18% (8~18%) off east Luzon. The discordant upstream-downstream trend was attributable to changes in oceanic eddies and basin surface winds: greater (lesser) cyclonic eddies, lesser (greater) anticyclonic eddies, and positive (negative) tendency in the Pacific Basin wind curl contributed to a weakened (intensified) downstream (upstream) Kuroshio. The difference in water mass between the upstream and downstream Kuroshio was balanced by an anomalous eastward flow, the southern branch of the Subtropical Counter Current which was enhanced and evacuated the redundant water eastward into the Pacific.

Several variants in the calcium channel Cav1.2 have been implicated in arrhythmic syndromes. We screened patients with Brugada syndrome, short QT syndrome, early repolarisation syndrome, and idiopathic ventricular fibrillation to determine the frequency and pathogenicity of Cav1.2 variants. Cav1.2 related genes, CACNA1C, CACNB2 and CACNA2D1, were screened in 65 probands. Missense variants were introduced in the Cav1.2 alpha subunit plasmid by mutagenesis to assess their pathogenicity using patch clamp approaches. Six missense variants were identified in CACNA1C in five individuals. Five of them, A1648T, A1689T, G1795R, R1973Q, C1992F, showed no major alterations of the channel function. The sixth C-terminal variant, Cavalpha1c-T1787M, present mostly in the African population, was identified in two patients with resuscitated cardiac arrest. The first patient originated from Cameroon and the second was an inhabitant of La Reunion Island with idiopathic ventricular fibrillation originating from Purkinje tissues. Patch-clamp analysis revealed that Cavalpha1c-T1787M reduces the calcium and barium currents by increasing the auto-inhibition mediated by the C-terminal part and increases the voltage-dependent inhibition. We identified a loss-of-function variant, Cavalpha1c-T1787M, present in 0.8% of the African population, as a new risk factor for ventricular arrhythmia. PMID- 30279521 TI - Developmental transitions in amygdala PKC isoforms and AMPA receptor expression associated with threat memory in infant rats. AB - Although infants learn and remember, they rapidly forget, a phenomenon known as infantile amnesia. While myriad mechanisms impact this rapid forgetting, the molecular events supporting memory maintenance have yet to be explored. To explore memory mechanisms across development, we used amygdala-dependent odor shock conditioning and focused on mechanisms important in adult memory, the AMPA receptor subunits GluA1/2 and upstream protein kinases important for trafficking AMPAR, protein kinase M zeta (PKMzeta) and iota/lambda (PKCiota/lambda). We use odor-shock conditioning in infant rats because it is late-developing (postnatal day, PN10) and can be modulated by corticosterone during a sensitive period in early life. Our results show that memory-related molecules did not change in pups too young to learn threat (PN8) but were activated in pups old enough to learn (PN12), with increased PKMzeta-PKCiota/lambda and GluA2 similar to that observed in adult memory, but with an uncharacteristic decrease in GluA1. This molecular signature and behavioral avoidance of the conditioned odor was recapitulated in PN8 pups injected with CORT before conditioning to precociously induce learning. Blocking learning via CORT inhibition in older pups (PN12) blocked the expression of these molecules. PN16 pups showed a more adult-like molecular cascade of increased PKMzeta-PKCiota/lambda and GluA1-2. Finally, at all ages, zeta inhibitory peptide (ZIP) infusions into the amygdala 24 hr after conditioning blocked memory. Together, these results identify unique features of memory processes across early development: AMPAR subunits GluA1/2 and PKC isoform expression are differentially used, which may contribute to mechanisms of early life forgetting. PMID- 30279523 TI - The evolutionary conserved FOXJ1 target gene Fam183b is essential for motile cilia in Xenopus but dispensable for ciliary function in mice. AB - The transcription factor FOXJ1 is essential for the formation of motile cilia throughout the animal kingdom. Target genes therefore likely constitute an important part of the motile cilia program. Here, we report on the analysis of one of these targets, Fam183b, in Xenopus and mice. Fam183b encodes a protein with unknown function which is conserved from the green algae Chlamydomonas to humans. Fam183b is expressed in tissues harbouring motile cilia in both mouse and frog embryos. FAM183b protein localises to basal bodies of cilia in mIMCD3 cells and of multiciliated cells of the frog larval epidermis. In addition, FAM183b interacts with NUP93, which also localises to basal bodies. During frog embryogenesis, Fam183b was dispensable for laterality specification and brain development, but required for ciliogenesis and motility of epidermal multiciliated cells and nephrostomes, i.e. the embryonic kidney. Surprisingly, mice homozygous for a null allele did not display any defects indicative of disrupted motile ciliary function. The lack of a cilia phenotype in mouse and the limited requirements in frog contrast with high sequence conservation and the correlation of gene expression with the presence of motile cilia. This finding may be explained through compensatory mechanisms at sites where no defects were observed in our FAM183b-loss-of-function studies.

AB - Gravitational forces can impose physical stresses on the human body as it functions to maintain homeostasis. It has been reported that astronauts exposed to microgravity experience altered biological functions and many subsequent studies on the effects of microgravity have therefore been conducted. However, the anticancer mechanisms of simulated microgravity remain unclear. We previously showed that the proliferation of human Hodgkin's lymphoma (HL) cells was inhibited when these cells were cultured in time-averaged simulated microgravity (taSMG). In the present study, we investigated whether taSMG produced an anticancer effect. Exposure of human HL cells to taSMG for 2 days increased their reactive oxygen species (ROS) production and NADPH oxidase family gene expression, while mitochondrial mass, ATPase, ATP synthase, and intracellular ATP levels were decreased. Furthermore, human HL cells exposed to taSMG underwent autophagy via AMPK/Akt/mTOR and MAPK pathway modulation; such autophagy was inhibited by the ROS scavenger N-acetylcysteine (NAC). These results suggest an innovative therapeutic approach to HL that is markedly different from conventional chemotherapy and radiotherapy. PMID- 30279526 TI - LOTUS domain protein MARF1 binds CCR4-NOT deadenylase complex to post transcriptionally regulate gene expression in oocytes. AB - Post-transcriptional regulation of gene expression plays an essential role during oocyte maturation. Here we report that Drosophila MARF1 (Meiosis Regulator And mRNA Stability Factor 1), which consists of one RNA-recognition motif and six tandem LOTUS domains with unknown molecular function, is essential for oocyte maturation. When tethered to a reporter mRNA, MARF1 post-transcriptionally silences reporter expression by shortening reporter mRNA poly-A tail length and thereby reducing reporter protein level. This activity is mediated by the MARF1 LOTUS domain, which binds the CCR4-NOT deadenylase complex. MARF1 binds cyclin A mRNA and shortens its poly-A tail to reduce Cyclin A protein level during oocyte maturation. This study identifies MARF1 as a regulator in oocyte maturation and defines the conserved LOTUS domain as a post-transcriptional effector domain that recruits CCR4-NOT deadenylase complex to shorten target mRNA poly-A tails and suppress their translation. PMID- 30279528 TI - Control of proline utilization by the Lrp-like regulator PutR in Caulobacter crescentus. AB - Cellular metabolism recently emerged as a central player modulating the bacterial cell cycle. The Alphaproteobacterium Caulobacter crescentus appears as one of the best models to study these connections, but its metabolism is still poorly characterized. Considering that it lives in oligotrophic environments, its capacity to use amino-acids is often critical for its growth. Here, we characterized the C. crescentus PutA bi-functional enzyme and showed that it is required for the utilization of proline as a carbon source. We also found that putA transcription and proline utilization by PutA are strictly dependent on the Lrp-like PutR activator. The activation of putA by PutR needs proline, which most likely acts as an effector molecule for PutR. Surprisingly, we also observed that an over-production of PutR leads to cell elongation in liquid medium containing proline, while it inhibits colony formation even in the absence of proline on solid medium. These cell division and growth defects were equally pronounced in a DeltaputA mutant background, indicating that PutR can play other roles beyond the control of proline catabolism. Altogether, these findings suggest that PutR might connect central metabolism with cell cycle processes. PMID- 30279527 TI - Chronic noise exposure exacerbates AD-like neuropathology in SAMP8 mice in relation to Wnt signaling in the PFC and hippocampus. AB - Non-genetic environmental hazards are thought to be associated with genetic susceptibility factors that increase Alzheimer's disease (AD) pathogenesis. Aging and chronic noise exposure have been considered important factors in the AD. Here, we investigated the impact of chronic noise exposure on the AD-like neuropathology in the senescence-accelerated prone mouse (SAMP8) and the underlying mechanisms of such effects. We examined the consequences of AD-like neuropathology in 3-month-old SAMP8 mice using low- and high-intensity noise exposure and 8-month-old SAMP8 mice as aging positive controls. Immunoblotting and immunohistochemistry were conducted to examine AD-like pathological changes and potential mechanisms. Chronic noise exposure led to progressive overproduction of Abeta and increased the hyperphosphorylation of tau at Ser396, Thr205, and Thr231 sites in the hippocampus and the prefrontal cortex (PFC) in young SAMP8 mice, similar to that observed in aging SAMP8 mice. Both noise exposure and aging could cause a significant downregulation in Wnt signaling expression. These findings demonstrate that chronic noise stress exacerbated AD like neuropathology, possibly by disrupting Wnt signaling and triggering aberrant tau hyperphosphorylation and Abeta in the PFC and hippocampus. PMID- 30279529 TI - Human and mouse albumin bind their respective neonatal Fc receptors differently. AB - Albumin has a serum half-life of three weeks in humans and is utilized to extend the serum persistence of drugs that are genetically fused or conjugated directly to albumin or albumin-binding molecules. Responsible for the long half-life is FcRn that protects albumin from intracellular degradation. An in-depth understanding of how FcRn binds albumin across species is of importance for design and evaluation of albumin-based therapeutics. Albumin consists of three homologous domains where domain I and domain III of human albumin are crucial for binding to human FcRn. Here, we show that swapping of two loops in domain I or the whole domain with the corresponding sequence in mouse albumin results in reduced binding to human FcRn. In contrast, humanizing domain I of mouse albumin improves binding. We reveal that domain I of mouse albumin plays a minor role in the interaction with the mouse and human receptors, as domain III on its own binds with similar affinity as full-length mouse albumin. Further, we show that P573 in domain III of mouse albumin is required for strong receptor binding. Our study highlights distinct differences in structural requirements for the interactions between mouse and human albumin with their respective receptor, which should be taken into consideration in design of albumin-based drugs and evaluation in mouse models. PMID- 30279530 TI - Identification of target genes for RNAi-mediated control of the Twospotted Spider Mite. AB - RNA interference (RNAi) is being developed for the management of pests that destroy crops. The twospotted Spider Mite (TSSM), Tetranychus urticae is a worldwide pest due to its unique physiological and behavioral characteristics including extraordinary ability to detoxify a wide range of pesticides and feed on many host plants. In this study, we conducted experiments to identify target genes that could be used for the development of RNAi-based methods to control TSSM. Leaf disc feeding assays revealed that knockdown in the expression genes coding for proteins involved in the biosynthesis and action of juvenile hormone (JH) and action of ecdysteroids [Methoprene-tolerant (Met), retinoid X receptor beta, farnesoic acid O-methyltransferase, and CREB-binding protein] caused 35-56% mortality. Transgenic tobacco plants expressing hairpin dsRNA targeting Met gene were generated and tested. About 48% mortality was observed in TSSM raised on transgenic tobacco plants expressing dsMet. These studies not only broaden our knowledge on understanding hormone action in TSSM but also identified target genes that could be used in RNAi-mediated control of TSSM. PMID- 30279531 TI - A genetic perspective on the relationship between eudaimonic -and hedonic well being. AB - Whether hedonism or eudaimonia are two distinguishable forms of well-being is a topic of ongoing debate. To shed light on the relation between the two, large scale available molecular genetic data were leveraged to gain more insight into the genetic architecture of the overlap between hedonic and eudaimonic well being. Hence, we conducted the first genome-wide association studies (GWAS) of eudaimonic well-being (N = ~108 K) and linked it to a GWAS of hedonic well-being (N = ~222 K). We identified the first two genome-wide significant independent loci for eudaimonic well-being and six independent loci for hedonic well-being. Joint analyses revealed a moderate phenotypic correlation (r = 0.53) and a high genetic correlation (rg = 0.78) between eudaimonic and hedonic well-being. This indicates that the genetic etiology of hedonic and eudaimonic well-being is substantially shared, with divergent (environmental) factors contributing to their phenotypic divergence. Loci regulating expression showed significant enrichment in the brain cortex, brain cerebellum, frontal cortex, as well as the cerebellar hemisphere for eudaimonic well-being. No significant enrichment for hedonic well-being is observed, although brain tissues were top ranked. Genetic correlations patterns with a range of positive and negative related phenotypes were largely similar for hedonic -and eudaimonic well-being. Our results reveal a large overlap between the genes that influence hedonism and the genes that influence eudaimonia. PMID- 30279534 TI - Autosomal dominant PKD gets an atomic map. PMID- 30279532 TI - Chemogenetic generation of hydrogen peroxide in the heart induces severe cardiac dysfunction. AB - Oxidative stress plays an important role in the pathogenesis of many disease states. In the heart, reactive oxygen species are linked with cardiac ischemia/reperfusion injury, hypertrophy, and heart failure. While this correlation between ROS and cardiac pathology has been observed in multiple models of heart failure, the independent role of hydrogen peroxide (H2O2) in vitro and in vivo is unclear, owing to a lack of tools for precise manipulation of intracellular redox state. Here we apply a chemogenetic system based on a yeast D-amino acid oxidase to show that chronic generation of H2O2 in the heart induces a dilated cardiomyopathy with significant systolic dysfunction. We anticipate that chemogenetic approaches will enable future studies of in vivo H2O2 signaling not only in the heart, but also in the many other organ systems where the relationship between redox events and physiology remains unclear. PMID- 30279533 TI - How phosphorylation influences E1 subunit pyruvate dehydrogenase: A computational study. AB - Pyruvate (PYR) dehydrogenase complex (PDC) is an enzymatic system that plays a crucial role in cellular metabolism as it controls the entry of carbon into the Krebs cycle. From a structural point of view, PDC is formed by three different subunits (E1, E2 and E3) capable of catalyzing the three reaction steps necessary for the full conversion of pyruvate to acetyl-CoA. Recent investigations pointed out the crucial role of this enzyme in the replication and survival of specific cancer cell lines, renewing the interest of the scientific community. Here, we report the results of our molecular dynamics studies on the mechanism by which posttranslational modifications, in particular the phosphorylation of three serine residues (Ser-264-alpha, Ser-271-alpha, and Ser-203-alpha), influence the enzymatic function of the protein. Our results support the hypothesis that the phosphorylation of Ser-264-alpha and Ser-271-alpha leads to (1) a perturbation of the catalytic site structure and dynamics and, especially in the case of Ser-264 alpha, to (2) a reduction in the affinity of E1 for the substrate. Additionally, an analysis of the channels connecting the external environment with the catalytic site indicates that the inhibitory effect should not be due to the occlusion of the access/egress pathways to/from the active site.

PMID- 30279537 TI - A magnetically recyclable photocatalyst with commendable dye degradation activity at ambient conditions. AB - An efficient, economical, environment-friendly and easy separable catalyst to treat environmental contaminants is an enduring attention in recent years due to their great potential for environmental protection and remediation. Here we have reported the excellent performance of polyaniline activated heterojunctured Ni0.5Zn0.5Fe2O4 catalyst to degrade azo dye in an aqueous solution at ambient condition. The catalyst was prepared via a simple facile polymerization procedure. The physicochemical properties and structure of the synthesized catalyst was confirmed by TGA, PXRD, FTIR, SEM, HRTEM, XPS, EDX, and DRS techniques. The developed catalyst has shown an accelerated degradation ability of an organic pollutant Orange ll Sodium salt azo dye about 100% for the dye concentration of 50 ppm within five minutes at ambient conditions with 1 g/l loading of catalyst. Simple facile synthesis, easy separation by an external magnet, good reusability and high degradation capability of the catalyst may promote the practical applications of the heterostructured catalyst at ambient condition for water remediation. The present study also explored possible credible charge transfer directions and mechanism of photocatalysis supported by trapping experiments and electrochemical impedance spectroscopy (EIS) measurement for the effective improvement of photocatalytic activity and enhancement of the visible light adsorption. PMID- 30279536 TI - Solar simulated light exposure alters metabolization and genotoxicity induced by benzo[a]pyrene in human skin. AB - Skin is a major barrier against external insults and is exposed to combinations of chemical and/or physical toxic agents. Co-exposure to the carcinogenic benzo[a]pyrene (B[a]P) and solar UV radiation is highly relevant in human health, especially in occupational safety. In vitro studies have suggested that UVB enhances B[a]P genotoxicity by activating the AhR pathway and overexpressing the cytochrome P450 enzymes responsible for the conversion of B[a]P into DNA damaging metabolites. Our present work involved more realistic conditions, namely ex vivo human skin explants and simulated sunlight (SSL) as a UV source. We found that topically applied B[a]P strongly induced expression of cutaneous cytochrome P450 genes and formation of DNA adducts. However, gene induction was significantly reduced when B[a]P was combined with SSL. Consequently, formation of BPDE-adducts was also reduced when B[a]P was associated with SSL. Similar results were obtained with primary cultures of human keratinocytes. These results indicate that UV significantly impairs B[a]P metabolism, and decreases rather than increases immediate toxicity. However, it cannot be ruled out that decreased metabolism leads to accumulation of B[a]P and delayed genotoxicity. PMID- 30279539 TI - A Frequency Independent Framework for Synthesis of Programmable Non-reciprocal Networks. AB - Passive and linear nonreciprocal networks at microwave frequencies hold great promises in enabling new front-end architectures for wireless communication systems. Their non-reciprocity has been achieved by disrupting the time-reversal symmetry using various forms of biasing schemes, but only over a limited frequency range. Here we demonstrate a framework for synthesizing theoretically frequency-independent multi-port nonreciprocal networks. The framework is highly expandable and can have an arbitrary number of ports while simultaneously sustaining balanced performance and providing unprecedented programmability of non-reciprocity. A 4-port circulator based on such a framework is implemented and tested to produce a broadband nonreciprocal performance from 10 MHz to 900 MHz with a temporal switching effort at 23.8 MHz. With the combination of broad bandwidth, low temporal effort, and high programmability, the framework could inspire new ways of implementing multiple input multiple output (MIMO) communication systems for 5G. PMID- 30279538 TI - Chromatin architecture changes and DNA replication fork collapse are critical features in cryopreserved cells that are differentially controlled by cryoprotectants. AB - In this work, we shed new light on the highly debated issue of chromatin fragmentation in cryopreserved cells. Moreover, for the first time, we describe replicating cell-specific DNA damage and higher-order chromatin alterations after freezing and thawing. We identified DNA structural changes associated with the freeze-thaw process and correlated them with the viability of frozen and thawed cells. We simultaneously evaluated DNA defects and the higher-order chromatin structure of frozen and thawed cells with and without cryoprotectant treatment. We found that in replicating (S phase) cells, DNA was preferentially damaged by replication fork collapse, potentially leading to DNA double strand breaks (DSBs), which represent an important source of both genome instability and defects in epigenome maintenance. This induction of DNA defects by the freeze thaw process was not prevented by any cryoprotectant studied. Both in replicating and non-replicating cells, freezing and thawing altered the chromatin structure in a cryoprotectant-dependent manner. Interestingly, cells with condensed chromatin, which was strongly stimulated by dimethyl sulfoxide (DMSO) prior to freezing had the highest rate of survival after thawing. Our results will facilitate the design of compounds and procedures to decrease injury to cryopreserved cells. PMID- 30279540 TI - Pyrophosphate inhibits gluconeogenesis by restricting UDP-glucose formation in vivo. AB - Pyrophosphate (PPi) is produced by anabolic reactions and serves as an energy donor in the cytosol of plant cells; however, its accumulation to toxic levels disrupts several common biosynthetic pathways and is lethal. Before acquiring photosynthetic capacity, young seedlings must endure a short but critical heterotrophic period, during which they are nourished solely by sugar produced from seed reserves by the anabolic process of gluconeogenesis. Previously, we reported that excess PPi in H+-PPase-knockout fugu5 mutants of Arabidopsis thaliana severely compromised gluconeogenesis. However, the precise metabolic target of PPi inhibition in vivo remained elusive. Here, CE-TOF MS analyses of major metabolites characteristic of gluconeogenesis from seed lipids showed that the Glc6P;Fru6P level significantly increased and that Glc1P level was consistently somewhat higher in fugu5 compared to wild type. In contrast, the UDP Glc level decreased significantly in the mutants. Importantly, specific removal of PPi in fugu5, and thus in AVP1pro:IPP1 transgenic lines, restored the Glc1P and the Glc6P;Fru6P levels, increased the UDP-Glc level ~2.0-fold, and subsequently increased sucrose synthesis. Given the reversible nature of the Glc1P/UDP-Glc reaction, our results indicate that UGP-Glc pyrophosphorylase is the major target when excess PPi exerts inhibitory effects in vivo. To validate our findings, we analyzed metabolite responses using a mathematical theory called structural sensitivity analysis (SSA), in which the responses of concentrations in reaction systems to perturbations in enzyme activity are determined from the structure of the network alone. A comparison of our experimental data with the results of pure structural theory predicted the existence of unknown reactions as the necessary condition for the above metabolic profiles, and confirmed the above results. Our data support the notion that H+-PPase plays a pivotal role in cytosolic PPi homeostasis in plant cells. We propose that the combination of metabolomics and SSA is powerful when seeking to identify and predict metabolic targets in living cells. PMID- 30279541 TI - A Non-Targeted LC-MS Profiling Reveals Elevated Levels of Carnitine Precursors and Trimethylated Compounds in the Cord Plasma of Pre-Eclamptic Infants. AB - Preeclampsia (PE) is a complex pregnancy disorder. It is not extensively known how the metabolic alterations of PE women contribute to the metabolism of newborn. We applied liquid chromatography-mass spectrometry (LC-MS) based non targeted metabolomics to determine whether the metabolic profile of plasma from umbilical cord differs between infants born to PE and non-PE pregnancies in the FINNPEC study. Cord plasma was available from 42 newborns born from PE and 53 from non-PE pregnancies. 133 molecular features differed between PE and non-PE newborns after correction for multiple testing. Decreased levels of 4-pyridoxic acid were observed in the cord plasma samples of PE newborns when compared to non PE newborns. Compounds representing following areas of metabolism were increased in the cord plasma of PE newborns: urea and creatine metabolism; carnitine biosynthesis and acylcarnitines; putrescine metabolites; tryptophan metabolism and phosphatidylcholines. To our knowledge, this study is the first one to apply LC-MS based metabolomics in cord plasma of PE newborns. We demonstrate that this strategy provides a global picture of the widespread metabolic alterations associated with PE and particularly the elevated levels of carnitine precursors and trimethylated compounds appear to be associated with PE at birth. PMID- 30279542 TI - Genome sequencing of Prototheca zopfii genotypes 1 and 2 provides evidence of a severe reduction in organellar genomes. AB - Prototheca zopfii (P. zopfii, class Trebouxiophyceae, order Chlorellales, family Chlorellaceae), a non-photosynthetic predominantly free-living unicellular alga, is one of the few pathogens belonging to the plant kingdom. This alga can affect many vertebrate hosts, sustaining systemic infections and diseases such as mastitis in cows. The aim of our work was to sequence and assemble the P. zopfii genotype 1 and genotype 2 mitochondrial and plastid genomes. Remarkably, the P. zopfii mitochondrial (38 Kb) and plastid (28 Kb) genomes are models of compaction and the smallest known in the Trebouxiophyceae. As expected, the P. zopfii genotype 1 and 2 plastid genomes lack all the genes involved in photosynthesis, but, surprisingly, they also lack those coding for RNA polymerases. Our results showed that plastid genes are actively transcribed in P. zopfii, which suggests that the missing RNA polymerases are substituted by nuclear-encoded paralogs. The simplified architecture and highly-reduced gene complement of the P. zopfii mitochondrial and plastid genomes are closer to those of P. stagnora and the achlorophyllous obligate parasite Helicosporidium than to those of P. wickerhamii or P. cutis. This similarity is also supported by maximum likelihood phylogenetic analyses inferences. Overall, the P. zopfii sequences reported here, which include nuclear genome drafts for both genotypes, will help provide both a deeper understanding of the evolution of Prototheca spp. and insights into the corresponding host/pathogen interactions. PMID- 30279543 TI - A novel system-level approach using RNA-sequencing data identifies miR-30-5p and miR-142a-5p as key regulators of apoptosis in myocardial infarction. AB - This study identified microRNAs involved in myocardial infarction (MI) through a novel system-level approach using RNA sequencing data in an MI mouse model. This approach involved the extraction of DEGs and DEmiRs from RNA-seq data in sham and MI samples and the subsequent selection of two miRNAs: miR-30-5p (family) and miR 142a-5p, which were downregulated and upregulated in MI, respectively. Gene Set Enrichment Analysis (GSEA) using the predicted targets of the two miRNAs suggested that apoptosis is an essential gene ontology (GO)-associated term. In vitro functional assays using neonatal rat ventricular myocytes (NRVMs) demonstrated that miR-30-5p is anti-apoptotic and miR-142a-5p is pro-apoptotic. Luciferase assays showed that the apoptotic genes, Picalm and Skil, and the anti apoptotic genes, Ghr and Kitl, are direct targets of miR-30-5p and miR-142a-5p, respectively. siRNA studies verified the results of the luciferase assays for target validation. The results of the system-level high throughput approach identified a pair of functionally antagonistic miRNAs and their targets in MI. This study provides an in-depth analysis of the role of miRNAs in the pathogenesis of MI which could lead to the development of therapeutic tools. The system-level approach could be used to identify miRNAs involved in variety of other diseases. PMID- 30279544 TI - The intracellular proteome of African swine fever virus. AB - African swine fever (ASF) is a viral disease that affects members of the Suidae family such as African bush pigs, warthogs, but also domestic pigs, and wild boar. It is transmitted by direct contact of naive with infected animals, by soft ticks of the Ornithodoros genus, or indirectly by movement of infected animals, improper disposal of contaminated animal products or other sources related to human activity. The recent spread of ASF into Eastern and Central European countries is currently threatening the European pig industry. The situation is aggravated as to-date no efficient vaccine is available. African swine fever virus (ASFV) is a large enveloped ds DNA-virus encoding at least 150 open reading frames. Many of the deduced gene products have not been described, less functionally characterized. We have analysed ASFV protein expression in three susceptible mammalian cell lines representing a susceptible host (wild boar) and two non-susceptible species (human and green monkey) by mass spectrometry and provide first evidence for the expression of 23 so far uncharacterized ASFV ORFs. Expression levels of several newly identified ASFV proteins were remarkably high indicating importance in the viral replication cycle. Moreover, expression profiles of ASFV proteins in the three cell lines differed markedly. PMID- 30279545 TI - Contrast-enhanced ultrasound tractography for 3D vascular imaging of the prostate. AB - Diffusion tensor tractography (DTT) enables visualization of fiber trajectories in soft tissue using magnetic resonance imaging. DTT exploits the anisotropic nature of water diffusion in fibrous structures to identify diffusion pathways by generating streamlines based on the principal diffusion vector. Anomalies in these pathways can be linked to neural deficits. In a different field, contrast enhanced ultrasound is used to assess anomalies in blood flow with the aim of locating cancer-induced angiogenesis. Like water diffusion, blood flow and transport of contrast agents also shows a principal direction; however, this is now determined by the local vasculature. Here we show how the tractographic techniques developed for magnetic resonance imaging DTT can be translated to contrast-enhanced ultrasound, by first estimating contrast flow velocity fields from contrast-enhanced ultrasound acquisitions, and then applying tractography. We performed 4D in-vivo contrast-enhanced ultrasound of three human prostates, proving the feasibility of the proposed approach with clinically acquired datasets. By comparing the results to histopathology after prostate resection, we observed qualitative agreement between the contrast flow tracts and typical markers of cancer angiogenic microvasculature: higher densities and tortuous geometries in tumor areas. The method can be used in-vivo using a standard contrast-enhanced ultrasound protocol, opening up new possibilities in the area of vascular characterization for cancer diagnostics. PMID- 30279547 TI - Counterfactual Bell-State Analysis. AB - The Bell-state analysis to distinguish between the four maximally entangled Bell states requires the joint measurement on entangled particles. However, spatially separated parties cannot perform the joint measurement. In this paper, we present a counterfactual Bell-state analysis based on the chained quantum Zeno effect. This counterfactual analysis not only enables us to perform a complete Bell-state analysis, but also enables spatially separated parties to distinguish between the four Bell states without transmitting any physical particle over the channel. PMID- 30279546 TI - Authenticity and geographic origin of global honeys determined using carbon isotope ratios and trace elements. AB - Honey is the world's third most adulterated food. The addition of cane sugar or corn syrup and the mislabelling of geographic origin are common fraudulent practices in honey markets. This study examined 100 honey samples from Australia (mainland and Tasmania) along with 18 other countries covering Africa, Asia, Europe, North America and Oceania. Carbon isotopic analyses of honey and protein showed that 27% of commercial honey samples tested were of questionable authenticity. The remaining 69 authentic samples were subject to trace element analysis for geographic determination. One-way ANOVA analysis showed a statistical difference (p < 0.05) in trace element concentrations of honey from Australian regions and different continents. Principal component analysis (PCA) and canonical discriminant analysis (CDA) coupled with C5.0 classification modelling of honey carbon isotopes and trace element concentrations showed distinct clusters according to their geographic origin. The C5.0 model revealed trace elements Sr, P, Mn and K can be used to differentiate honey according to its geographic origin. The findings show the common and prevalent issues of honey authenticity and the mislabelling of its geographic origin can be identified using a combination of stable carbon isotopes and trace element concentrations. PMID- 30279548 TI - NMR spectroscopy enables simultaneous quantification of carbohydrates for diagnosis of intestinal and gastric permeability. AB - Increased intestinal or gastric permeability is one of the major hallmarks of liver cirrhosis. The current gold standard for diagnosis of aberrant gut permeability due to disease is the triple-sugar test, where carbohydrates are orally administered and urinary excretion is measured. Hereby, elevated lactulose levels indicate intestinal permeability, whereas increased sucrose levels reveal gastric permeability. However, reliable detection and quantification of these sugars in a complex biological fluid still remains challenging due to interfering substances. Here we used Nuclear Magnetic Resonance (NMR) spectroscopy with a simple and fast protocol, without any additional sample extraction steps, for straight-forward simultaneous quantification of sugars in urine in order to detect increased intestinal and gastric permeability. Collected urine samples were diluted in buffer and one- and two-dimensional proton spectra were recorded in order to reveal carbohydrate concentrations in individual urine samples containing mannitol, sucrose and/or lactulose. Overall, this article presents a fast and robust method for simultaneous quantification of different sugars down to low micro-molar concentrations for research studies and can be further extended for clinical studies with automation of the quantification process.

AB - This study is aimed to investigate whether simvastatin induces cardiomyocytes survival signaling in endotoxin (lipopolysaccharide, LSP)-induced myocardial injury, and if so, further to determine a role of survivin in simvastatin-anti apoptotic effect. Wistar rats were pretreated with simvastatin (10-40 mg/kg po) before a single non-lethal dose of LPS. In myocardial tissue, LPS induced structural disorganization of myofibrils with significant inflammatory infiltrate (cardiac damage score, CDS = 3.87 +/- 0.51, p < 0.05), whereas simvastatin dose dependently abolished structural changes induced by LPS (p < 0.01). Simvastatin in 20 mg/kg and 40 mg/kg pretreatment, dose dependently, attenuated myocardial apoptosis determined as apoptotic index (28.8 +/- 4.5% and 18.9 +/- 3.5, p < 0.05), decreased cleaved caspase-3 expression (32.1 +/- 5.8%, p < 0.01), along with significant Bcl-xL expression in the simvastatin groups (p < 0.01). Interestingly, in the simvastatin groups were determined significantly increased expression of survivin (p < 0.01), but in negative correlation with cleaved caspase-3 and apoptotic indices (p < 0.01). Simvastatin has a cardioprotective effects against LPS induced apoptosis. The effect may be mediated by up regulation of survivin via activation of NF-kappaB, which leads to reduced activation of caspase-3 and consequent apoptosis of cardiomyocytes in experimental sepsis. PMID- 30279550 TI - Atorvastatin provides a new lipidome improving early regeneration after partial hepatectomy in osteopontin deficient mice. AB - Osteopontin (OPN), a multifunctional cytokine that controls liver glycerolipid metabolism, is involved in activation and proliferation of several liver cell types during regeneration, a condition of high metabolic demands. Here we investigated the role of OPN in modulating the liver lipidome during regeneration after partial-hepatectomy (PH) and the impact that atorvastatin treatment has over regeneration in OPN knockout (KO) mice. The results showed that OPN deficiency leads to remodeling of phosphatidylcholine and triacylglycerol (TG) species primarily during the first 24 h after PH, with minimal effects on regeneration. Changes in the quiescent liver lipidome in OPN-KO mice included TG enrichment with linoleic acid and were associated with higher lysosome TG hydrolase activity that maintained 24 h after PH but increased in WT mice. OPN-KO mice showed increased beta-oxidation 24 h after PH with less body weight loss. In OPN-KO mice, atorvastatin treatment induced changes in the lipidome 24 h after PH and improved liver regeneration while no effect was observed 48 h post-PH. These results suggest that increased dietary-lipid uptake in OPN-KO mice provides the metabolic precursors required for regeneration 24 h and 48 h after PH. However, atorvastatin treatment offers a new metabolic program that improves early regeneration when OPN is deficient. PMID- 30279551 TI - Spider silk proteome provides insight into the structural characterization of Nephila clavipes flagelliform spidroin. AB - The capture spiral of web from N. clavipes spider consists of a single type of spidroin - the flagelliform silk protein, a natural material representing a combination of strength and high elasticity. Flagelliform spider silk is the most extensible silk fibre produced by orb weaver spiders and the structure of this remarkable material is still largely unknown. In the present study we used a proteomic approach to elucidate the complete sequence and the post-translational modifications of flagelliform silk proteins. The long sequence of flagelliform silk protein presents 45 hydroxylated proline residues, which may contribute to explain the mechanoelastic property of these fibres, since they are located in the GPGGX motif. The 3D-structure of the protein was modelled considering the three domains together, i.e., the N- and C-terminal non-repetitive domains, and the central repetitive domain. In the resulting molecular model there is a predominance of random structures in the solid fibres of the silk protein. The N terminal domain is composed of three alpha-helices and the C-terminal domain is composed of one small helical section. Proteomic data reported herein may be relevant for the development of novel approaches for the synthetic or recombinant production of novel silk-based spider polymers. PMID- 30279552 TI - Robustness of Voltage-induced Magnetocapacitance. AB - One of the most important achievements in the field of spintronics is the development of magnetic tunnel junctions (MTJs). MTJs exhibit a large tunneling magnetoresistance (TMR). However, TMR is strongly dependent on biasing voltage, generally, decreasing with applying bias. The rapid decay of TMR was a major deficiency of MTJs. Here we report a new phenomenon at room temperature, in which the tunneling magnetocapacitance (TMC) increases with biasing voltage in an MTJ system based on Co40Fe40B20/MgO/Co40Fe40B20. We have observed a maximum TMC value of 102% under appropriate biasing, which is the largest voltage-induced TMC effect ever reported for MTJs. We have found excellent agreement between theory and experiment for the bipolar biasing regions using Debye-Frohlich model combined with quartic barrier approximation and spin-dependent drift-diffusion model. Based on our calculation, we predict that the voltage-induced TMC ratio could reach 1100% in MTJs with a corresponding TMR value of 604%. Our work has provided a new understanding on the voltage-induced AC spin-dependent transport in MTJs. The results reported here may open a novel pathway for spintronics applications, e.g., non-volatile memories and spin logic circuits.

AB - Exosomes have shown increasing potential as delivery vesicles for therapy, but challenges like cost/yield, drug payload, and targeting specificity still exist. Plant derived exosome-like nanoparticles have been reported as a promising substitution and exhibit biocompatibility through oral, intranasal administration; however, systemic delivery of siRNA by exosome-like nanoparticles directly isolated from plants has not been reported. Recently, we reported the control of RNA orientation to decorate human derived exosome with cell targeting ligands for specific delivery of siRNA to tumors. Here, we expand to the application of arrowtail RNA nanoparticles for displaying ligands on ginger derived exosome-like nanovesicles (GDENs) for siRNA delivery and tumor inhibition through IV administration. Cushion ultracentrifugation coupled with equilibrium density gradient ultracentrifugation were used for purifying GDENs that displayed size, density, and morphology similar to human derived exosomes. Folic acid (FA), as a ligand, was displayed on the surface of GDENs for targeted delivery of survivin siRNA to KB cancer models. In vitro gene knockdown efficacy by FA 3WJ/GDENs/siRNA complex was comparable to transfection. We observed inhibition of tumor growth on a xenograft model by intravenous administration, which reveals the potential of GDENs as an economic delivery system for siRNA. PMID- 30279554 TI - Development of a deep residual learning algorithm to screen for glaucoma from fundus photography. AB - The Purpose of the study was to develop a deep residual learning algorithm to screen for glaucoma from fundus photography and measure its diagnostic performance compared to Residents in Ophthalmology. A training dataset consisted of 1,364 color fundus photographs with glaucomatous indications and 1,768 color fundus photographs without glaucomatous features. A testing dataset consisted of 60 eyes of 60 glaucoma patients and 50 eyes of 50 normal subjects. Using the training dataset, a deep learning algorithm known as Deep Residual Learning for Image Recognition (ResNet) was developed to discriminate glaucoma, and its diagnostic accuracy was validated in the testing dataset, using the area under the receiver operating characteristic curve (AROC). The Deep Residual Learning for Image Recognition was constructed using the training dataset and validated using the testing dataset. The presence of glaucoma in the testing dataset was also confirmed by three Residents in Ophthalmology. The deep learning algorithm achieved significantly higher diagnostic performance compared to Residents in Ophthalmology; with ResNet, the AROC from all testing data was 96.5 (95% confidence interval [CI]: 93.5 to 99.6)% while the AROCs obtained by the three Residents were between 72.6% and 91.2%. PMID- 30279555 TI - Comparative study of substrate free and amniotic membrane scaffolds for cultivation of limbal epithelial sheet. AB - Transplantation of cultivated limbal epithelial transplantation has been proven to restore the corneal surface in limbal stem cell deficiency (LSCD). Here we comparatively investigated the optimized conditions and the efficiency of limbal epithelial sheet growth in three media conditions as well as with substrate free (transwell), human amniotic membrane (HAM) sutured onto transwell inserts (HAMTW), and HAM slide scaffold (HAMS). Outcomes evaluated were outgrowth sheet size from limbal explants, expression of stem/progenitor cell markers p63alpha, ABCG2 and CK15, and colony formation efficiency (CFE). Additionally, limbal epithelial sheets on HAMS were transplanted into corneas of LSCD rabbit models. Limbal epithelial sheets with 5% human AB serum showed the greatest increase in ABCG2 efflux activity (JC1low), p63alpha expression, and CFE compared in both conditions without HAM and with HAM, respectively. The outgrowth sheet size, cell yield, and Ki67 expression were increased in limbal epithelial sheets on HAMS compared to transwell and HAMTW. ABCG2 efflux activity, p63alpha and CK15 expressions, and CFE were also increased in limbal epithelial sheets on HAMS as well. In corneas of transplanted rabbit LSCD models, p63alpha expressions were noted in the basal layers and CK12 expressions were observed in superficial layers. Cultivation of limbal epithelial sheet on HAMS with xeno-free medium enhances the growth and stemness of limbal epithelial sheets.

PMID- 30279556 TI - Analysis of the antimicrobial mechanism of porcine beta defensin 2 against E. coli by electron microscopy and differentially expressed genes. AB - Porcine beta defensin 2 (pBD2) is a cationic antimicrobial peptide with broad spectrum antibacterial activity, which makes it a potential alternative to antibiotics to prevent and cure diseases of pigs. However, development of pBD2 as an effective antibiotic agent requires molecular understanding of its functional mechanism against pathogens. In this study, we investigated the functional mechanism of pBD2 antibacterial activity. Escherichia coli was incubated with different pBD2 concentrations for different times. Electron microscopy was used to analyze the locations of pBD2 and its induced morphological changes in E. coli. Gene expression analysis was also performed to further understand the molecular changes of E. coli in response to pBD2 incubation. The results demonstrated that E. coli membranes were broken, holed, and wrinkled after treatment with pBD2, and pBD2 was located on the cell membranes and manly in the cytoplasm. Furthermore, 38 differentially expressed genes (DEGs) were detected, successfully sequenced and confirmed by quantitative real-time PCR (qRT-PCR). Most of the known functional DEGs were associated with DNA transcription and translation and located in the cytoplasm. Collectively, the results suggest that pBD2 could have multiple modes of action and the main mechanism for killing E. coli might be influence on DNA transcription and translation by targeting intracellular molecules after membrane damage, although transport and metabolism proteins were also affected. PMID- 30279558 TI - Dynamics of error-related activity in deterministic learning - an EEG and fMRI study. AB - There is a close relationship between progress in learning and the error monitoring system. EEG and fMRI studies using probabilistic learning have revealed the distinct dynamics of this system after response and feedback, i.e. an increase of error-related and a decrease of feedback-related activity in the anterior cingulate cortex (ACC). Based on the existing theories, it can be presumed that during deterministic learning feedback-related activity in ACC would also increase. Since these assumptions have not yet been confirmed, it can be only speculated based on the data from the probabilistic paradigms how the information is being integrated within the ACC during deterministic learning. Here we implemented the Paired Associate Deterministic Learning task to the EEG and fMRI experiments. The analysis of EEG data showed a significant increase in the amplitude for both ERN and FN. Similarly, the fMRI results showed an increase in response-related and feedback-related activity of the ACC in erroneous trials. Our findings are in line with the current theories of ACC function: increasing ACC activity can be linked to the detected discrepancy between expected and obtained outcomes. We argue that expectancy violations in the course of deterministic learning are signalled by both, internal and external evaluation system. PMID- 30279559 TI - Profiling circRNA and miRNA of radiation-induced esophageal injury in a rat model. AB - Evidence has also shown that micro ribonucleic acid (miRNA) plays an important role in many cellular processes. However, it is unclear how ionizing radiation causes the miRNA and circular ribonucleic acid (circRNA) expression levels to change and how this change relates to esophageal injury. We analyzed RNA Sequencing (RNA-seq) data from normal esophageal tissue and irradiated esophageal tissues and used computational approaches to identify and characterize differentially expressed miRNAs and circRNAs. We detected 27 miRNAs and 197 circRNAs that had significantly different expression levels after ionizing radiation treatment compared with normal control.Among the 27 miRNAs, 7 miRNAs were down-regulated, and the other 20 were up-regulated. Their target genes were found to be involved in responses to wound, lipid biosynthesis, cell proliferation, cell migration, chemokine activity, hairpin binding, and the cell membrane system. We also found 197 differentially expressed circRNAs in total, of which 87 were up-regulated and 110 were down-regulated. Notably, we found that differentially expressed circRNAs were enriched in cell differentiation, epithelial cell migration, striatum development, protein binding, extracellular exosome, and focal adhesion functions. Of the related processes, sphingolipid metabolism was notable. Many of the differentially expressed circRNAs were involved in sphingolipid metabolism pathways. Cells responded to ionizing radiation (IR) using multiple pathways, which led to sphingolipid metabolism and other immune responses, ultimately leading to esophageal injury.IR-induced esophageal injury is worth studying, especially the dynamic network of circRNA and miRNA. By knowing the regulatory details of related pathways, radiation related esophageal injury can be prevented, and the efficiency of radiation therapy can be enhanced.

AB - Understanding the impact of weather fluctuations on demographic parameters is of crucial interest to biodiversity research in a context of global climate change. Amphibians are valuable candidates for investigating this topic due to their strong physiological dependence on water availability and temperature. In this study, we took advantage of data from a long-term capture-mark-recapture (CMR) monitoring program of a great crested newt (Triturus cristatus) population inhabiting a 12-pond archipelago in southeastern France. We investigated the interactions between vital rates (survival and recruitment), the internal structure of the population, and climatic variables both at a local and a regional (North Atlantic Oscillation: NAO) scale. Overall, we found a weak relationship between climatic variables and the survival of large-bodied newts. The only strong relationship was found to be a high NAO index during the post breeding period, suggesting that dry, hot summers negatively impact survival. In terms of recruitment, the results indicated that hot weather during the activity period had delayed deleterious effects on adult recruitment two years later, suggesting high larval and juvenile mortality due to unsuitable growing conditions. Recruitment was also impacted by a high NAO index during the overwintering period preceding recruitment, suggesting that mild weather increases the mortality of juveniles, probably by enhancing the depletion of energy reserves without any possibility of refueling. PMID- 30279561 TI - In Utero Heat Stress Alters the Offspring Epigenome. AB - Exposure to intrauterine heat stress during late gestation affects offspring performance into adulthood. However, underlying mechanistic links between thermal insult in fetal life and postnatal outcomes are not completely understood. We examined morphology, DNA methylation, and gene expression of liver and mammary gland for bull calves and heifers that were gestated under maternal conditions of heat stress or cooling (i.e. in utero heat stressed vs. in utero cooled calves). Mammary tissue was harvested from dairy heifers during their first lactation and liver from bull calves at birth. The liver of in utero heat stressed bull calves contained more cells and the mammary glands of in utero heat stressed heifers were comprised of smaller alveoli. We identified more than 1,500 CpG sites differently methylated between maternal treatment groups. These CpGs were associated with approximately 400 genes, which play a role in processes, such as development, innate immune defense, cell signaling, and transcription and translation. We also identified over 100 differentially expressed genes in the mammary gland with similar functions. Interestingly, fifty differentially methylated genes were shared by both bull calf liver and heifer mammary gland. Intrauterine heat stress alters the methylation profile of liver and mammary DNA and programs their morphology in postnatal life, which may contribute to the poorer performance of in utero heat stressed calves. PMID- 30279564 TI - Exacerbated fires in Mediterranean Europe due to anthropogenic warming projected with non-stationary climate-fire models. AB - The observed trend towards warmer and drier conditions in southern Europe is projected to continue in the next decades, possibly leading to increased risk of large fires. However, an assessment of climate change impacts on fires at and above the 1.5 degrees C Paris target is still missing. Here, we estimate future summer burned area in Mediterranean Europe under 1.5, 2, and 3 degrees C global warming scenarios, accounting for possible modifications of climate-fire relationships under changed climatic conditions owing to productivity alterations. We found that such modifications could be beneficial, roughly halving the fire-intensifying signals. In any case, the burned area is robustly projected to increase. The higher the warming level is, the larger is the increase of burned area, ranging from ~40% to ~100% across the scenarios. Our results indicate that significant benefits would be obtained if warming were limited to well below 2 degrees C. PMID- 30279566 TI - 'FORWARD GENETICS' AND THE CAUSES OF ALS. PMID- 30279563 TI - The imprinted gene Pw1/Peg3 regulates skeletal muscle growth, satellite cell metabolic state, and self-renewal. AB - Pw1/Peg3 is an imprinted gene expressed from the paternally inherited allele. Several imprinted genes, including Pw1/Peg3, have been shown to regulate overall body size and play a role in adult stem cells. Pw1/Peg3 is expressed in muscle stem cells (satellite cells) as well as a progenitor subset of muscle interstitial cells (PICs) in adult skeletal muscle. We therefore examined the impact of loss-of-function of Pw1/Peg3 during skeletal muscle growth and in muscle stem cell behavior. We found that constitutive loss of Pw1/Peg3 function leads to a reduced muscle mass and myofiber number. In newborn mice, the reduction in fiber number is increased in homozygous mutants as compared to the deletion of only the paternal Pw1/Peg3 allele, indicating that the maternal allele is developmentally functional. Constitutive and a satellite cell-specific deletion of Pw1/Peg3, revealed impaired muscle regeneration and a reduced capacity of satellite cells for self-renewal. RNA sequencing analyses revealed a deregulation of genes that control mitochondrial function. Consistent with these observations, Pw1/Peg3 mutant satellite cells displayed increased mitochondrial activity coupled with accelerated proliferation and differentiation. Our data show that Pw1/Peg3 regulates muscle fiber number determination during fetal development in a gene-dosage manner and regulates satellite cell metabolism in the adult. PMID- 30279565 TI - Facial expression and oxytocin as possible markers of positive emotions in horses. AB - Behavioural and physiological markers of discrete positive emotions remain little investigated in animals. To characterise new markers in horses, we used tactile stimulations to induce emotional situation of contrasting valence. In the Gentle grooming group (G, N = 13) horses were gently groomed during 11 sessions on the body areas they appreciated the most. Horses in the Standard grooming group (S, N = 14) were groomed using a fixed procedure, reported to induce avoidance reactions in some horses. At session 11, G horses expressed significantly more contact-seeking behaviours than S horses, which expressed significantly more avoidance behaviours. This result suggests positive emotions in G horses and negative emotions in S horses. Blood cortisol, oxytocin, heart rate and heart rate variability never differed between before and after the grooming session. However, after the 11 sessions, basal oxytocin levels were lower in the G than in the S group. This difference was unexpected, but supports studies showing that a low level of basal oxytocin could be a marker of better well-being. Analyses of facial expressions during grooming revealed significant differences between groups. These expressions appear to be more sensitive than behavioural indicators because they alone enabled differentiating emotions according to the group when horses were re-exposed to neutral grooming one year after the treatment. PMID- 30279568 TI - Relationship between the Second to Fourth Finger Length Ratio and Calcaneus Quantitative Ultrasound. AB - This study aimed to characterize the relationship between the ratio of the length of the second and fourth fingers (2D:4D value) and the speed of sound of the calcaneus by quantitative ultrasound (QUS-SOS) in undergraduate female students. We recruited 138 young women with a mean age of 19.6 +/- 1.4 years. The participants' calcaneus QUS-SOS was measured using an ultrasound bone densitometer. We also measured the participants' weight, height, and grip strength. A self-reported questionnaire was used to obtain information on participants' secondary sexual characteristics, and exercise habits. The present study showed that the 2D:4D value of both hands was significantly correlated with the calcaneus QUS-SOS. The 2D:4D value of the left hand was also positively associated with the calcaneus QUS-SOS results in several respects. These findings suggest that the 2D:4D value may be useful for the screening of risk for a low bone quality in undergraduate female students. PMID- 30279567 TI - Autophagy and Akt in the protective effect of erythropoietin helix B surface peptide against hepatic ischaemia/reperfusion injury in mice. AB - Helix B surface peptide (HBSP) is an erythropoietin (EPO)-derived peptide that protects tissue from the risks of elevated blood pressure and thrombosis. This study focused on the protection of HBSP in hepatic ischaemia/reperfusion (I/R) by enhancing the level of autophagy. In detail, we randomly divided C57BL/6 mice into sham-operated, hepatic ischaemia/reperfusion (I/R), I/R + HBSP, I/R + HBSP + 3-methyladenine (autophagy inhibitor), I/R + HBSP + rapamycin (mTOR inhibitor), and I/R + HBSP + Ly294002 (Akt inhibitor) groups. We assessed alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) levels in mouse sera, and performed haematoxylin/eosin (HE) staining, immunohistochemistry, electron microscopy, immunofluorescence microscopy, and western blotting on liver tissue to detect the degree of liver injury, liver apoptosis, autophagy, and the expression of microtubule associated protein 1 light chain 3 alpha (Map1lc3, or LC3), Beclin 1, phospho-mTOR, mTOR, phospho-Akt (P-Akt), and Akt. HBSP relieved hepatic I/R injury in a concentration independent manner. The expression of LC3II, LC3I, and Beclin 1, and the formation of autophagosomes, in the I/R + HBSP group were higher than those in the I/R group. The protective effects of HBSP were abolished by 3-methyladenine and, to a lesser extent, Ly294002, but enhanced by rapamycin. Furthermore, In vivo, HBSP also protected against hypoxia injury induced by cobalt chloride (CoCl2) through improving the level of autophagy. Therefore, HBSP protected against hepatic I/R injury, mainly via regulating autophagy by targeting mTOR.

AB - In this study, hybrid graphene-Pt/TiO2 nanostructure were synthesized by single step, inexpensive and surfactant/organic solvent free route; hydrothermal technique. The physicochemical properties of hybrid graphene-Pt/TiO2 nanostructure were carefully analyzed by multiple techniques, including X-ray diffractometer (XRD), X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscope (FESEM) and transmission electron microscope (TEM). The synthesized hybrid nanostructures were utilized as photocatalyst for the degradation of methylene blue (MB) dye under natural environment at average ambient temperature and mean daily global solar radiation, of about 22-25 degrees C and 374.9 mWh/cm2, respectively. The activity performance indicated considerable degradation of methylene blue (MB) dye and was in the following order Gr (13%), TiO2 (60%) and hybrid graphene-Pt/TiO2 nanostructure (90%) over 21 min under the natural light illumination. The physiochemical characterization suggests that, the tightly attached metalized TiO2 nanoparticles (Pt-TiO2) on the high surface area graphene sheets improved utilization of visible light and increased separation and transfer of photo-excited electron (e) hole (h+) pairs. Notably, the hybrid graphene-Pt/TiO2 nanostructure exhibited an excellent cyclic stability for methylene blue (MB) dye removal. Finally, the kinetic behavior indicated that the photocatalytic degradation reaction of the dye obeyed the pseudo-first order (Langmuir-Hinshelwood) kinetics model.

AB - Foot-and-mouth disease (FMD) is a highly contagious disease of livestock affecting animal production and trade throughout Asia and Africa. Understanding FMD virus (FMDV) global movements and evolution can help to reconstruct the disease spread between endemic regions and predict the risks of incursion into FMD-free countries. Global expansion of a single FMDV lineage is rare but can result in severe economic consequences. Using extensive sequence data we have reconstructed the global space-time transmission history of the O/ME-SA/Ind-2001 lineage (which normally circulates in the Indian sub-continent) providing evidence of at least 15 independent escapes during 2013-2017 that have led to outbreaks in North Africa, the Middle East, Southeast Asia, the Far East and the FMD-free islands of Mauritius. We demonstrated that sequence heterogeneity of this emerging FMDV lineage is accommodated within two co-evolving divergent sublineages and that recombination by exchange of capsid-coding sequences can impact upon the reconstructed evolutionary histories. Thus, we recommend that only sequences encoding the outer capsid proteins should be used for broad-scale phylogeographical reconstruction. These data emphasise the importance of the Indian subcontinent as a source of FMDV that can spread across large distances and illustrates the impact of FMDV genome recombination on FMDV molecular epidemiology. PMID- 30279573 TI - Pre-transplant expressions of microRNAs, comorbidities, and post-transplant mortality. AB - We analyzed micro-RNAs (miRs) as possible diagnostic biomarkers for relevant comorbidities prior to and prognostic biomarkers for mortality following hematopoietic cell transplantation (HCT). A randomly selected group of patients (n = 36) were divided into low-risk (HCT-comorbidity index [HCT-CI] score of 0 and survived HCT) and high-risk (HCT-CI scores >= 4 and deceased after HCT) groups. There were 654 miRs tested and 19 met the pre-specified significance level of p < 0.1. In subsequent models, only eight miRs maintained statistical significance in regression models after adjusting for baseline demographic factors; miRs-374b and -454 were underexpressed, whereas miRs-142-3p, -191, -424, -590-3p, -29c, and -15b were overexpressed among high-risk patients relative to low-risk patients. Areas under the curve for these eight miRs ranged between 0.74 and 0.81, suggesting strong predictive capacity. Consideration of miRs may improve risk assessment of mortality and should be further explored in larger future prospective studies. PMID- 30279572 TI - Urinary Exosomal and cell-free DNA Detects Somatic Mutation and Copy Number Alteration in Urothelial Carcinoma of Bladder. AB - Urothelial bladder carcinoma (UBC) is characterized by a large number of genetic alterations. DNA from urine is a promising source for liquid biopsy in urological malignancies. We aimed to assess the availability of cell-free DNA (cfDNA) and exosomal DNA (exoDNA) in urine as a source for liquid biopsy in UBC. We included 9 patients who underwent surgery for UBC and performed genomic profiling of tumor samples and matched urinary cfDNA and exoDNA. For mutation analysis, deep sequencing was performed for 9 gene targets and shallow whole genome sequencing (sWGS) was used for the detection of copy number variation (CNV). We analyzed whether genetic alteration in tumor samples was reflected in urinary cfDNA or exoDNA. To measure the similarity between copy number profiles of tumor tissue and urinary DNA, the Pearson's correlation coefficient was calculated. We found 17 somatic mutations in 6 patients. Of the 17 somatic mutations, 14 and 12 were identified by analysis of cfDNA and exoDNA with AFs of 56.2% and 65.6%, respectively. In CNV analysis using sWGS, although the mean depth was 0.6X, we found amplification of MDM2, ERBB2, CCND1 and CCNE1, and deletion of CDKN2A, PTEN and RB1, all known to be frequently altered in UBC. CNV plots of cfDNA and exoDNA showed a similar pattern with those from the tumor samples. Pearson's correlation coefficients of tumor vs. cfDNA (0.481) and tumor vs. exoDNA (0.412) were higher than that of tumor vs. normal (0.086). We successfully identified somatic mutations and CNV in UBC using urinary cfDNA and exoDNA. Urinary exoDNA could be another source for liquid biopsy. Also, CNV analysis using sWGS is an alternative strategy for liquid biopsy, providing data from the whole genome at a low cost. PMID- 30279574 TI - Prof. Franco Mandelli: Leukaemia therapy pioneer. PMID- 30279575 TI - The effect of NIMA matching in adult unrelated mismatched hematopoietic stem cell transplantation - a joint study of the Acute Leukemia Working Party of the EBMT and the CIBMTR. AB - Hematological malignancies can be cured by unrelated donor allogeneic HSCT and outcomes are optimized by high-resolution HLA matching at HLA-A, -B, -C, -DRB1 and -DQB1 (10/10 match). If a 10/10 match is unavailable, 9/10 matches may be suitable. Fetal exposure to non-inherited maternal antigens (NIMA) may impart lifelong NIMA tolerance modulating the immune response, as shown in adult haploidentical transplantation. In cord blood transplantation, NIMA matching lowered rates of aGvHD and TRM; in haploidentical transplantation, sibling donors with non-shared maternal antigens showed less grade II-IV aGvHD. This retrospective analysis examined if 9/10 matched unrelated donor HSCT benefits from NIMA matching. DKMS contacted 1,735 donors and obtained 733 (42%) maternal samples. NIMA-matched and -mismatched cases with a minimum follow-up of 1 year were compared by univariate and multivariate analyses adjusted for co-variates for OS, DFS, relapse, TRM and a/cGvHD. The study population (N = 445) comprised 31 NIMA-matched and 414 NIMA-mismatched cases. No significant differences between NIMA-matched and NIMA-mismatched groups were found for any outcomes with similar OS and TRM rates within both groups. This study provides the proof of principle that NIMA matching is possible in the unrelated donor HSCT setting; larger studies may be able to provide significant results.

PMID- 30279578 TI - Prostate cancer disparities in Hispanics by country of origin: a nationwide population-based analysis. AB - BACKGROUND: We sought to evaluate prostate cancer (PCa) characteristics and outcomes of Hispanics living in the United States by country of origin in the Surveillance, Epidemiology and End Results (SEER) program. METHODS: Retrospective analysis of 72,134 adult Hispanics with PCa between 1995 and 2014. Origin was Mexican (N = 16,995; 24%), South/Central American (N = 6949; 10%), Puerto Rican (N = 3582; 5%), Cuban (N = 2587; 4%), Dominican (N = 725; 1%), Hispanic not specified (NOS, N = 41,296; 57%), as coded by SEER. Patient and PCa characteristics were analyzed with chi-square and Kruskal-Wallis tests. Overall and PCa survival were analyzed with Kaplan-Meier and Cox models adjusting for baseline variables. RESULTS: At diagnosis, Mexicans had more advanced stage, higher prostate-specific antigen, and higher Gleason score while Cubans and Dominicans had more favorable PCa at diagnosis (all P < 0.05). After a median follow-up of 69 months, 20,317 men died, including 6223 PCa deaths. Compared to Mexicans, Cubans (HR = 1.22, 95% CI = [1.14-1.30]) and Puerto Ricans (HR = 1.15 [1.08-1.22]) had worse overall survival while Dominicans (HR = 0.76 [0.64-0.91]), South/Central Americans (HR = 0.68 [0.65-0.72]), and NOS (HR = 0.81 [0.78-0.84]) had better overall survival. Compared to Mexicans, Cubans (HR = 1.08 [0.96-1.22]) and Puerto Ricans (HR = 1.03 [0.92-1.15]) had similar PCa survival while Dominicans (HR = 0.72 [0.53-0.98]), South/Central Americans (HR = 0.67 [0.60 0.74]), and NOS (HR = 0.68 [0.64-0.73]) had significantly better PCa survival. CONCLUSIONS: Among Hispanics in the United States, disparities in PCa characteristics and survival by country of origin exist, with Dominicans, South/Central Americans, and Hispanic NOS having better PCa survival compared to Mexicans, Cubans, and Puerto Ricans. PMID- 30279579 TI - PTEN status assessment in the Johns Hopkins active surveillance cohort. AB - BACKGROUND: Up to half of men with Gleason score 6 (GS6) prostate cancers initially managed with active surveillance (AS) will eventually require definitive therapy, usually due to tumor grade reclassification during follow-up. We examined the association between PTEN status on biopsy and subsequent clinicopathologic outcomes in men with GS6 cancers who enrolled in AS. METHODS: We performed a case-control study of men enrolled in the Johns Hopkins AS cohort with diagnostic biopsy tissue available for immunohistochemical (IHC) staining. IHC was performed for PTEN using genetically validated protocols for all patients. Cases included men who underwent grade reclassification to GS >= 3 + 4 = 7 on biopsy within 2 years of follow-up (i.e., early reclassification) or reclassification to GS >= 4 + 3 = 7 on biopsy or radical prostatectomy during follow-up (i.e., extreme reclassification). Control patients were diagnosed with GS6 cancer and monitored on AS for at least 8 years without undergoing biopsy reclassification. RESULTS: Among 67 cases with adequate tissue, 31 men underwent early reclassification and 36 men underwent extreme reclassification. Cases were compared to 65 control patients with adequate tissue for assessment. On initial prostate biopsy, cases were older (median age 67 vs. 65, p = 0.024) and were less likely to meet very-low-risk criteria (64 vs 79%, p = 0.042) as compared to controls. Although not statistically significant, PTEN loss was observed in only 1 (1.5%) of 65 controls as compared to 6 (9%) of 67 cases (p = 0.062). CONCLUSIONS: PTEN loss was rare among men with GS6 prostate cancer enrolled in AS at Johns Hopkins. Despite this, PTEN loss was more frequent among men who underwent early or extreme reclassification to higher-grade cancer as compared to controls. Additional studies in larger low-risk cohorts may better elucidate a potential role for PTEN in selecting patients for AS. PMID- 30279580 TI - Impact of age on exposure to oral antiandrogen therapies in clinical practice. AB - BACKGROUND: Oral antiandrogen therapies are predominantly used in older men, but real-life studies evaluating the impact of age on pharmacokinetic exposure are lacking. This study aims to evaluate the impact of age on the pharmacokinetic profiles of abiraterone acetate and enzalutamide in clinical practice. PATIENTS AND METHODS: Retrospective observational study to evaluate the impact of age on the first steady-state sample of patients treated with abiraterone acetate or enzalutamide in routine daily clinical practice. The effect of age on target attainment was assessed. RESULTS: For abiraterone acetate and enzalutamide, 71 and 64 patients were included, respectively. Baseline patients' characteristics and administered doses were not age-dependent. No age-related differences were observed in exposure to the main metabolites of abiraterone acetate, except for active metabolite Delta(4)-Abiraterone (D4A) with a median plasma concentration of 2.5 * 10-3 mg/L in the oldest versus 1.3 * 10-3 mg/L in the youngest age quartile (coefficient of variation, CV, 72%, p = 0.03). For enzalutamide, no significant differences in exposure were found, except for carboxylic acid enzalutamide, having a median plasma concentration of 5.8 mg/L versus 3.9 mg/L in the oldest versus the youngest age quartile (CV 66%, p = 0.03). However, this was driven by one patient aged 99 years old. Age had no significant influence on target attainment of either compound. CONCLUSIONS: This study showed no significant impact of age on the pharmacokinetic profiles of abiraterone acetate and enzalutamide, except for the active metabolite D4A and the inactive metabolite carboxylic acid enzalutamide, both having significantly higher exposure in older males. Target attainments of abiraterone and enzalutamide were not significantly affected by age, which suggests that age has no clinically relevant impact on exposure to these oral antiandrogen therapies. However, the clinical impact of higher exposure to D4A in older males remains undetermined. PMID- 30279581 TI - Predictors of fluoroquinolone-resistant bacteria in the rectal vault of men undergoing prostate biopsy. AB - IMPORTANCE: Fluoroquinolone (FQ)-resistant rectal vault flora is associated with infectious complications in men undergoing transrectal ultrasound-guided prostate needle biopsy (TRUS-PNB). OBJECTIVE: To determine the patient factors that predict FQ-resistant rectal cultures in men who are undergoing transrectal ultrasound-guided prostate needle biopsy. METHODS: An IRB approved retrospective review of 6183 consecutive men who had undergone a rectal swab culture in preparation for TRUS-PNB between January 2013 and December 2014 was performed. Multivariable logistic regression was used to determine the clinical and demographic factors associated with FQ-resistant Enterobacteriaceae in the rectal vault. RESULTS: Of the 6179 rectal swabs analyzed, 4842 (78%) were FQ-sensitive, and 1337 (22%) were FQ-resistant. On univariable analysis, increasing age, prior TRUS-PNB, higher number of biopsy cores obtained, diabetes mellitus, antimicrobial use within the past 6 months and non-Caucasian race were predictors of FQ-resistance (all p < 0.05). Men with FQ-resistant cultures were more likely to have benign pathology on TRUS-PNB (p = 0.004). On multivariable analysis, increasing patient age (OR = 1.01/year [1.00-1.02]), use of antimicrobials in the last 6 months (OR = 2.85[2.18-3.72]), African American (OR = 1.99 [1.66-2.37]), Asian (OR = 3.39 [2.63-4.37]), and Hispanic (OR = 2.10 [1.72-2.55]) races were independently associated with FQ-resistant rectal cultures. The overall infectious rate was 1.1% (56/5214) and the sepsis rate was 0.46% (24/5214). The infection rate in the FQ-resistant group was 3.9% (43/1107) compared to FQ sensitive group 0.3% (13/4107), p < 0.001. CONCLUSION: In this cohort, increasing age, recent antimicrobial-use, and non-Caucasian race were independent predictors of FQ-resistance in the rectal vault. As FQ-resistance is associated with infectious complications from transrectal ultrasound-guided prostate needle biopsy, understanding risk factors may assist infection control efforts. PMID- 30279582 TI - Impact of age, comorbidity, and PSA doubling time on long-term competing risks for mortality among men with non-metastatic castration-resistant prostate cancer. AB - BACKGROUND: Understanding competing risks for mortality is critical in determining prognosis among men with non-metastatic castration-resistant prostate cancer (nmCRPC), a disease state that often affects older men and has substantial heterogeneity in risk of cancer mortality. We sought to determine the impact of age, comorbidity, and PSA doubling time (PSADT) on competing risks for mortality in men with nmCRPC. METHODS: We conducted a retrospective analysis of 1238 patients diagnosed with nmCRPC in 2000-2015 in the SEARCH database. Multivariable Cox proportional hazards and competing risks regression were used to determine the hazards of overall, prostate cancer-specific (PCSM), and other-cause mortality (OCM) across age, Charlson comorbidity index (CCI), and PSADT subgroups. RESULTS: Men with nmCRPC were elderly (median age 77) and had substantial comorbidity burdens (CCI > 1 n = 701, 57%). Multivariable Cox analysis showed higher CCI was associated with higher hazard of OCM, while slower PSADT was associated with lower hazard of PCSM across all age subgroups. Among those with CCI >= 3 (vs. CCI0), the hazard ratio of OCM was 2.7 (95% CI 1.1-6.3), 2.0 (95% CI 1.1-3.6), and 2.5 (95% CI 1.5-4.0) for those aged <70, 70-79, and >=80, respectively. Among those with PSADT >= 9 months (vs. < 9 months), the hazard ratios for PCSM were 0.5 (95% CI 0.3-0.9), 0.6 (95% CI 0.4-0.9), and 0.6 (95% CI 0.4-0.9) for those aged <70, 70-79, and >=80. Competing risks curves revealed PCSM was the predominant cause of death for those with PSADT < 9 months across all age and comorbidity groups. PCSM and OCM were relatively equal competitors for mortality among those with PSADT>=9 months except those aged > 80 with CCI >= 3, in whom OCM was the predominant cause of death. CONCLUSIONS: Among men with nmCRPC, age, comorbidity, and PSADT are associated with risk and cause of death and may assist clinicians in counseling patients regarding cancer prognosis. PMID- 30279584 TI - Nutrition care guidelines for men with prostate cancer undergoing androgen deprivation therapy: do we have enough evidence? AB - BACKGROUND: To review the evidence available to support clinical practice guidelines for dietary interventions aimed at mitigating the side effects of androgen deprivation therapy (ADT) in men with prostate cancer, and to identify future research priorities. METHODS: An analytical model was designed to select and interpret evidence for the effect of dietary interventions on ADT side effects. Key terms identified articles that investigated dietary interventions to mitigate ADT side effects among men treated for prostate cancer. Medline, Embase, Proquest, CINAHL, Cochrane databases, and PubMed were searched from inception through June, 2018. Clinical trial registries were also searched for up-to-date study protocols. Articles were not restricted on design. Methodological quality was assessed using the mixed methods appraisal tool. RESULTS: Sixteen articles met inclusion criteria, each with distinct dietary interventions. Twelve studies used interventions that combined diet with physical activity and/or medication and/or counselling. Four articles examined the effect of diet alone on ADT side effects. Of those, three articles measured changes to participants' dietary intake and influence on ADT side effects. One article showed daily caffeinated beverages improved cancer-related fatigue. Two articles showed no impact of isoflavone supplementation on hot flushes, quality of life, body mass index, or blood lipids. Dietary intake and compliance was poorly reported across all studies limiting knowledge of acceptability and feasibility for dietary interventions. Information on the nutrition care practices and views of clinicians treating men for prostate cancer is limited. No articles measured the impact of diet on long-term ADT side effects. Methodological quality of included papers ranged from weak to strong. CONCLUSIONS: Current evidence for dietary interventions to mitigate ADT side effects is limited. Further investigations are warranted to explore the impact of changes in dietary intake on ADT side effects before practice guidelines can be considered. PMID- 30279583 TI - Prostate Imaging Compared to Transperineal Ultrasound-guided biopsy for significant prostate cancer Risk Evaluation (PICTURE): a prospective cohort validating study assessing Prostate HistoScanning. AB - BACKGROUND: Men with negative prostate biopsies or those diagnosed with low-risk or low-volume intermediate-risk prostate cancers often require a second prostate biopsy prior to a treatment decision. Prostate HistoScanning (PHS) is an ultrasound imaging test that might inform prostate biopsy in such men. METHODS: PICTURE was a prospective, paired-cohort validating trial to assess the diagnostic accuracy of imaging in men requiring a further biopsy (clinicaltrials.gov, NCT01492270) (11 January 2012-29 January 2014). We enrolled 330 men who had undergone a prior TRUS biopsy but where diagnostic uncertainty remained. All eligible men underwent PHS and transperineal template prostate mapping (TTPM) biopsy (reference standard). Men were blinded to the imaging results until after undergoing TTPM biopsies. We primarily assessed the ability of PHS to rule out clinically significant prostate (negative predictive value [NPV] and sensitivity) for a target histological condition of Gleason >=4+3 and/or a cancer core length (MCCL) >=6 mm. We also assessed the role of visually estimated PHS-targeted biopsies. RESULTS: Of the 330 men enrolled, 249 underwent both PHS and TTPM biopsy. Mean (SD) age was 62 (7) years, median (IQR) PSA 6.8 (4.98-9.50) ng/ml, median (IQR) number of previous biopsies 1 (1-2) and mean (SD) gland size 37 (15.5) ml. One hundred and forty six (59%) had no clinically significant cancer. PHS classified 174 (70%) as suspicious. Sensitivity was 70.3% (95% CI 59.8-79.5) and NPV 41.3% (95% CI 27.0-56.8). Specificity and positive predictive value (PPV) were 14.7% (95% CI 9.1-22.0) and 36.8% (95% CI 29.6-44.4), respectively. In all, 213/220 had PHS suspicious areas targeted with targeting sensitivity 13.6% (95% CI 7.3-22.6), specificity 97.6% (95% CI 93.1-99.5), NPV 61.6% (95% CI 54.5-68.4) and PPV 80.0% (95% CI 51.9-95.7). CONCLUSIONS: PHS is not a useful test in men seeking risk stratification following initial prostate biopsy. PMID- 30279585 TI - Computational analysis of the amino acid interactions that promote or decrease protein solubility. AB - The solubility of globular proteins is a basic biophysical property that is usually a prerequisite for their functioning. In this study, we probed the solubility of globular proteins with the help of the statistical potential formalism, in view of objectifying the connection of solubility with structural and energetic properties and of the solubility-dependence of specific amino acid interactions. We started by setting up two independent datasets containing either soluble or aggregation-prone proteins with known structures. From these two datasets, we computed solubility-dependent distance potentials that are by construction biased towards the solubility of the proteins from which they are derived. Their analysis showed the clear preference of amino acid interactions such as Lys-containing salt bridges and aliphatic interactions to promote protein solubility, whereas others such as aromatic, His-pi, cation-pi, amino-pi and anion-pi interactions rather tend to reduce it. These results indicate that interactions involving delocalized pi-electrons favor aggregation, unlike those involving no (or few) dispersion forces. Furthermore, using our potentials derived from either highly or weakly soluble proteins to compute protein folding free energies, we found that the difference between these two energies correlates better with solubility than other properties analyzed before such as protein length, isoelectric point and aliphatic index. This is, to the best of our knowledge, the first comprehensive in silico study of the impact of residue residue interactions on protein solubility properties.The results of this analysis provide new insights that will facilitate future rational protein design applications aimed at modulating the solubility of targeted proteins. PMID- 30279587 TI - Synthesis and Evaluation of Herbal Chitosan from Ganoderma Lucidum Spore Powder for Biomedical Applications. AB - Chitosan is an extremely valuable biopolymer and is usually obtained as a byproduct from the shells of crustaceans. In the current work, chitosan is obtained from an herbal source (Ganoderma lucidum spore powder (GLSP)) for the first time. To show this, both standard (thermochemical deacetylation, (TCD)) and emerging (ultrasound-assisted deacetylation (USAD)) methods of chitosan preparation were used. The obtained chitosan was characterized by elemental analysis, XRD (X-ray diffraction), FT-IR (Fourier transform infrared spectroscopy) and thermogravimetric measurements. The process resulted in chitosan possessing comparable values of DD, [eta] and [Formula: see text] to the commercial product. Chitosan obtained via both processes (TCD and USAD) displayed excellent biocompatibility; although the USAD prepared biopolymer exhibited significantly improved fibroblast (L929 cell) viability and enhanced antibacterial zones for both Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). The findings of new herbal chitosan mark key developments of natural biomaterials; marking a potential shift from conventional sea-based organisms. PMID- 30279586 TI - Supplementation with a selective amino acid formula ameliorates muscular dystrophy in mdx mice. AB - Duchenne muscular dystrophy (DMD) is one of the most common and severe forms of muscular dystrophy. Oxidative myofibre content, muscle vasculature architecture and exercise tolerance are impaired in DMD. Several studies have demonstrated that nutrient supplements ameliorate dystrophic features, thereby enhancing muscle performance. Here, we report that dietary supplementation with a specific branched-chain amino acid-enriched mixture (BCAAem) increased the abundance of oxidative muscle fibres associated with increased muscle endurance in dystrophic mdx mice. Amelioration of the fatigue index in BCAAem-treated mdx mice was caused by a cascade of events in the muscle tissue, which were promoted by endothelial nitric oxide synthase (eNOS) activation and vascular endothelial growth factor (VEGF) expression. VEGF induction led to recruitment of bone marrow (BM)-derived endothelial progenitors (EPs), which increased the capillary density of dystrophic skeletal muscle. Functionally, BCAAem mitigated the dystrophic phenotype of mdx mice without inducing dystrophin protein expression or replacing the dystrophin-associated glycoprotein (DAG) complex in the membrane, which is typically lost in DMD. BCAAem supplementation could be an effective adjuvant strategy in DMD treatment. PMID- 30279589 TI - Multivariate analysis of short time series in terms of ensembles of correlation matrices. AB - When dealing with non-stationary systems, for which many time series are available, it is common to divide time in epochs, i.e. smaller time intervals and deal with short time series in the hope to have some form of approximate stationarity on that time scale. We can then study time evolution by looking at properties as a function of the epochs. This leads to singular correlation matrices and thus poor statistics. In the present paper, we propose an ensemble technique to deal with a large set of short time series without any consideration of non-stationarity. Given a singular data matrix, we randomly select subsets of time series and thus create an ensemble of non-singular correlation matrices. As the selection possibilities are binomially large, we will obtain good statistics for eigenvalues of correlation matrices, which are typically not independent. Once we defined the ensemble, we analyze its behavior for constant and block diagonal correlations and compare numerics with analytic results for the corresponding correlated Wishart ensembles. We discuss differences resulting from spurious correlations due to repetitive use of time-series. The usefulness of this technique should extend beyond the stationary case if, on the time scale of the epochs, we have quasi-stationarity at least for most epochs. PMID- 30279588 TI - Allosteric Role of Substrate Occupancy Toward the Alignment of P-glycoprotein Nucleotide Binding Domains. AB - P-glycoprotein (Pgp) is an ATP-binding cassette transporter that eliminates toxins from the cell but causes multidrug resistance in chemotherapies. The crystal structures of Pgp revealed drug-like compounds bound to an inward-facing conformation in which the energy-harnessing nucleotide binding domains (NBDs) were widely separated with no interfacial interaction. Following drug binding, inward-facing Pgp must transition to an NBD dimer conformation to achieve ATP binding and hydrolysis at canonical sites defined by both halves of the interface. However, given the high degree of flexibility shown for this transporter, it is difficult to envision how NBDs overcome entropic considerations for achieving proper alignment in order to form the canonical ATP binding site. We explored the hypothesis that substrate occupancy of the polyspecific drug-binding cavity plays a role in the proper alignment of NBDs using computational approaches. We conducted twelve atomistic molecular dynamics (MD) simulations (100-300 ns) on inward-facing Pgp in a lipid bilayer with and without small molecule substrates to ascertain effects of drug occupancy on NBD dimerization. Both apo- and drug-occupied simulations showed NBDs approaching each other compared to the crystal structures. Apo-Pgp reached a pseudo dimerization in which NBD signature motifs for ATP binding exhibited a significant misalignment during closure. In contrast, occupancy of three established substrates positioned by molecular docking achieved NBD alignment that was much more compatible with a canonical NBD dimerization trajectory. Additionally, aromatic amino acids, known to confer the polyspecific drug-binding characteristic of the internal pocket, may also govern polyspecific drug access to the cavity. The enrichment of aromatics comprising the TM4-TM6 portal suggested a preferential pathway over the aromatic-poor TM10-TM12 for lateral drug entry from the lipid bilayer. Our study also suggested that drug polyspecificity is enhanced due to a synergism between multiple drug-domain interactions involving 36 residues identified in TM1, 5, 6, 7, 11 and 12. PMID- 30279590 TI - Heterogeneity of a landscape influences size of home range in a North American cervid. AB - In the northeastern United States, chronic wasting disease has recently been detected in white-tailed deer (Odocoileus virginianus) populations, and understanding the relationship between landscape configuration and home range may improve disease surveillance and containment efforts. The objectives of our study were to compare size of home range for deer occupying a continuum of forested landscapes and to investigate relationships between size of home range and measures of landscape configuration. We used a movement-based kernel density estimator to estimate home range at five spatial scales among deer across study areas. We developed 7 linear regression models that used measures of the configuration of the forested landscape to explain size of home range. We observed differences in size of home range between sexes among areas that differed based on landscape configuration. We documented size of home range changed with various metrics that identifying connectivity of forested patches. Generally, size of home range increased with an increasing proportion of homogenous forest. Our results suggest that deer in our region occupy a landscape at hierarchically-nested scales that is controlled by the connectivity of the forested landscape across local or broad geographical regions.

PMID- 30279591 TI - An engineered arginine-rich alpha-helical antimicrobial peptide exhibits broad spectrum bactericidal activity against pathogenic bacteria and reduces bacterial infections in mice. AB - The increase in the prevalence of antibiotic-resistant bacteria has become a major public health concern. Antimicrobial peptides (AMPs) are emerging as promising candidates addressing this issue. In this study, we designed several AMPs by increasing alpha-helical contents and positive charges and optimizing hydrophobicity and amphipathicity in the Sushi 1 peptide from horseshoe crabs. A neural network-based bioinformatic prediction tool was used for the first stage evaluations of peptide properties. Among the peptides designed, Sushi-replacement peptide (SRP)-2, an arginine-rich and highly alpha-helical peptide, showed broad spectrum bactericidal activity against both Gram-positive and Gram-negative bacteria, including methicillin-resistant Staphylococcus aureus and multidrug resistant Acinetobacter baumannii; nevertheless, it showed little hemolytic and cytotoxic activity against mammalian cells. Atomic force microscopy results indicated that SRP-2 should interact directly with cell membrane components, resulting in bacterial cell death. SRP-2 also neutralized LPS-induced macrophage activation. Moreover, in an intraperitoneal multidrug-resistant A. baumannii infection mouse model, SRP-2 successfully reduced the bacterial number in ascitic fluid and tumor necrosis factor-alpha production. Our study findings demonstrate that bioinformatic calculations can be powerful tools to help design potent AMPs and that arginine is superior to lysine for providing positive charges for AMPs to exhibit better bactericidal activity and selectivity against bacterial cells.

PMID- 30279592 TI - Effect of Differences in Metabolic Activity of Melanoma Models on Response to Lonidamine plus Doxorubicin. AB - Lonidamine (LND), a metabolic modulator, sensitizes DB-1 human melanoma to doxorubicin (DOX) chemotherapy by acidifying and de-energizing the tumor. This report compares the effects of LND on two human melanoma lines, DB-1 and WM983B, which exhibit different metabolic properties. Using liquid chromatography mass spectrometry and Seahorse analysis, we show that DB-1 was more glycolytic than WM983B in vitro. 31P magnetic resonance spectroscopy (MRS) indicates that LND (100 mg/kg, i.p.) induces similar selective acidification and de-energization of WM983B xenografts in immunosuppressed mice. Over three hours, intracellular pH (pHi) of WM983B decreased from 6.91 +/- 0.03 to 6.59 +/- 0.10 (p = 0.03), whereas extracellular pH (pHe) of this tumor changed from 7.03 +/- 0.05 to 6.89 +/- 0.06 (p = 0.19). A decline in bioenergetics (beta-NTP/Pi) of 55 +/- 5.0% (p = 0.03) accompanied the decline in pHi of WM983B. Using 1H MRS with a selective multiquantum pulse sequence and Hadamard localization, we show that LND induced a significant increase in tumor lactate levels (p < 0.01). LND pre-treatment followed by DOX (10 mg/kg, i.v.) produced a growth delay of 13.7 days in WM983B (p < 0.01 versus control), a growth delay significantly smaller than the 25.4 days that occurred with DB-1 (p = 0.03 versus WM983B). Differences in relative levels of glycolysis may produce differential therapeutic responses of DB-1 and WM983B melanomas. PMID- 30279598 TI - Degree completion linked to peer support.

AB - BACKGROUND: The literature on brain imaging in premature infants is mostly made up of studies that evaluate neonates, yet the most dynamic time of brain development happens from birth to 1 year of age. This study was designed to obtain quantitative brain measures from magnetic resonance imaging scans of infants born prematurely at 12 months of age. METHODS: The subject group was designed to capture a wide range of gestational age (GA) from premature to full term infants. An age-specific atlas generated quantitative brain measures. A regression model was used to predict effects of GA and sex on brain measures. RESULTS: There was a primary effect of sex on: (1) intracranial volume, males > females; (2) proportional cerebral cortical gray matter (females > males), and (3) cerebral white matter (males > females). GA predicted cerebral volume and cerebral spinal fluid. GA also predicted cortical gray matter in a sex-specific manner with GA having a significant effect on cortical volume in the males, but not in females. CONCLUSIONS AND RELEVANCE: Sex differences in brain structure are large early in life. GA had sex-specific effects highlighting the importance evaluating sex effects in neurodevelopmental outcomes of premature infants.

AB - We report the photochemical carboxylation of o-phenylenedimamine in the absence of a base and an electron donor under an atmosphere of CO2, which afforded 2,3 diaminobenzoic acid (DBA) in 28% synthetic yield and 0.22% quantum yield (Phi(%)). The synthetic yield of DBA in this reaction increased to 58% (Phi(%) = 0.47) in the presence of Fe(II).

AB - This study was carried out to evaluate the effect of PEF process using static treatment chamber on fresh sugarcane juice with and without addition of lemon and ginger with respect to microbial content, chemical properties, nutrient content and shelf life extention of the product. The fresh sugar cane juice without addition of lemon and ginger treated at different field strengths (30 kV cm-1 and 50 kV cm-1) and different pulse numbers (150, 300) was initially investigated by storage at room temperature (31 degrees C) and refrigeration temperature (4 degrees C) for 30 days. The PEF effect on fresh sugar cane juice at room temperature and refrigerated temperature was compared with untreated sample (31 degrees C). At the end of the storage period samples treated at field strength 30 kV cm-1, 150 pulses were found to be stable compared with untreated sample. The second experimental study of PEF process was done on fresh sugarcane juice with the addition of lemon and ginger for fourteen days at different electric field intensities (10 kV cm-1, 20 kV cm-1 and 30 kV cm-1) with the same pulse number (150 pulses) and stored 4 degrees C. Even better reduction of microbes was achieved with PEF treatment condition of field strength 20 kV cm-1, 150 pulses in the presence of lemon and ginger. The sensory attributes of untreated fresh sugarcane juice were maintained up to only two days, but for the PEF treated sample, shelf life was extened up to seven days. Further, addition of lemon and ginger in the PEF treated sugarcane juice doubled the shelf life up to fourteen days.

Interventions: Investigators randomly selected 40 episodes of each of The Dr Oz Show and The Doctors from early 2013 and identified and evaluated all recommendations made on each program. A group of experienced evidence reviewers independently searched for, and evaluated as a team, evidence to support 80 randomly selected recommendations from each show. Main Outcomes Measures: Percentage of recommendations that are supported by evidence as determined by a team of experienced evidence reviewers. Secondary outcomes included topics discussed, the number of recommendations made on the shows, and the types and details of recommendations that were made. Results: We could find at least a case study or better evidence to support 54% (95% confidence interval 47% to 62%) of the 160 recommendations (80 from each show). For recommendations in The Dr Oz Show, evidence supported 46%, contradicted 15%, and was not found for 39%. For recommendations in The Doctors, evidence supported 63%, contradicted 14%, and was not found for 24%. Believable or somewhat believable evidence supported 33% of the recommendations on The Dr Oz Show and 53% on The Doctors. On average, The Dr Oz Show had 12 recommendations per episode and The Doctors 11. The most common recommendation category on The Dr Oz Show was dietary advice (39%) and on The Doctors was to consult a healthcare provider (18%). A specific benefit was described for 43% and 41% of the recommendations made on the shows respectively. The magnitude of benefit was described for 17% of the recommendations on The Dr Oz Show and 11% on The Doctors. Disclosure of potential conflicts of interest accompanied 0.4% of recommendations. Conclusions: Recommendations made on medical talk shows often lack adequate information on specific benefits or the magnitude of the effects of these benefits. Approximately half of the recommendations have either no evidence or are contradicted by the best available evidence. Potential conflicts of interest are rarely addressed. The public should be skeptical about recommendations made on medical talk shows. PMID- 30279613 TI - Missouri Medicine Annual Statement of Ownership, Management & Circulation.

AB - Oceanographers have an increasing responsibility to ensure that the outcomes of scientific research are conveyed to the policy-making sphere to achieve conservation and sustainable use of marine biodiversity. Zooplankton monitoring projects have helped to increase our understanding of the processes by which marine ecosystems respond to climate change and other environmental variations, ranging from regional to global scales, and its scientific value is recognized in the contexts of fisheries, biodiversity and global change studies. Nevertheless, zooplankton data have rarely been used at policy level for conservation and management of marine ecosystems services. One way that this can be pragmatically and effectively achieved is via the development of zooplankton indicators, which could for instance contribute to filling in gaps in the suite of global indicators to track progress against the Aichi Biodiversity Targets of the United Nations Strategic Plan for Biodiversity 2010-2020. This article begins by highlighting how under-represented the marine realm is within the current suite of global Aichi Target indicators. We then examine the potential to develop global indicators for relevant Aichi Targets, using existing zooplankton monitoring data, to address global biodiversity conservation challenges. PMID- 30279614 TI - Intranuclear Mobility of Estrogen Receptor: Implication for Transcriptional Regulation. AB - The estrogen receptor (ER) is a ligand-dependent transcription factor that has two subtypes: ERalpha and ERbeta. ERs regulate transcription of estrogen responsive genes through interactions with multiple intranuclear components, such as cofactors and the nuclear matrix. Live cell imaging using fluorescent protein labeled ERs has revealed that ligand-activated ERs are highly mobile in the nucleus, with transient association with the DNA and nuclear matrix. Scaffold attachment factor B (SAFB) 1 and its paralogue, SAFB2, are nuclear matrix-binding proteins that negatively modulate ERalpha-mediated transcription. Expression of SAFB1 and SAFB2 reduces the mobility of ERalpha in the presence of ligand. This regulatory machinery is emerging as an epigenetic-like mechanism that alters transcriptional activity through control of intranuclear molecular mobility. PMID- 30279616 TI - The 13C method as a robust alternative to 14C-based measurements of primary productivity in the Mediterranean Sea. AB - Due to the increasing constraints on using the radioactive isotope 14C to measure primary productivity (14C-PP), we determined the surface carbon fixation rates in the Mediterranean Sea, using the alternative stable isotope 13C method (13C-PP). Rates obtained (13C-POCp) were compared with simultaneous 14C-POCp measurements in samples of different volumes (72 mL and 1.2 L). We also tested the variation of the percentage of dissolved primary production (PER), to the total productivity using organic and inorganic filters (14C method). 13C-POCp rates ranged from 0.4, in the Ionian basin, to 1.5 mgC m-3 h-1 in the Ligurian region. These results agreed with those found with the 14C-PP in 1.2-L samples (two sample t-test, t = 1.035, df = 22, P = 0.31). However, we found that 14C-POCp rates derived from 72-mL incubations were 46% lower than those measured with 13C PP. The discrepancy between large and small volume incubations was likely due to differences in the number of large phytoplankton cells within the community. PER values measured with silver membrane filters yielded similar results than those obtained using polycarbonate filters. Our findings showed that when the sample size is carefully chosen, the 13C-PP provide comparable results to 14C-PP even in waters of low productivity in the Mediterranean Sea. PMID- 30279617 TI - 5-N-Carboxyimino-6-N-chloroaminopyrimidine-2,4(3H)-dione as a hypochlorite specific oxidation product of uric acid. AB - Although uric acid is known to react with many reactive oxygen species, its specific oxidation products have not been fully characterized. We now report that 5-N-carboxyimino-6-N-chloroaminopyrimidine-2,4(3H)-dione (CCPD) is a hypochlorite (ClO-)-specific oxidation product of uric acid. The yield of CCPD was 40-70% regardless of the rate of mixing of ClO- with uric acid. A previously reported product, allantoin (AL), was a minor product. Its yield (0-20%) decreased with decreasing rate of mixing of ClO- with uric acid, indicating that allantoin is less important in vivo. Kinetic studies revealed that the formation of CCPD required two molecules of ClO- per uric acid reacted. The identity of CCPD was determined from its molecular formula (C5H3ClN4O4) measured by LC/time-of-flight mass spectrometry and a plausible reaction mechanism. This assumption was verified by the fact that all mass fragments (m/z -173, -138, -113, and -110) fit with the chemical structure of CCPD and its tautomers. Isolated CCPD was stable at pH 6.0-8.0 at 37 degrees C for at least 6 h. The above results and the fact that uric acid is widely distributed in the human body at relatively high concentrations indicate that CCPD is a good marker of ClO- generation in vivo. PMID- 30279618 TI - Radical formation in individual aqueous solutions of some unsaturated fatty acids and in their mixtures. AB - This study examines oxidizability in individual aqueous solutions of oleic acid, linoleic acid, alpha-linolenic acid, gamma-linolenic acid and arachidonic acid, and in their mixtures. We used electron spin resonance (ESR), high performance liquid chromatography-electron spin resonance (HPLC-ESR) and high performance liquid chromatography-electron spin resonance-mass spectrometries (HPLC-ESR-MS). We detected 4-carboxybutyl radical derived from gamma-linolenic acid, ethyl and 7 carboxyheptyl radicals derived from alpha-linolenic acid, and pentyl and 7 carboxyheptyl radicals derived from linoleic acid. HPLC-ESR analyses for the individual aqueous solutions of linoleic acid, alpha-linolenic acid, gamma linolenic acid and arachidonic acid showed less radical form for polyunsaturated fatty acids with more double bonds. On the other hand, HPLC-ESR peak height of 4 carboxybutyl radical, which form through hydrogen atom abstraction at the carbon close to the carboxy end, increased for linoleic acid/gamma-linolenic acid, alpha linolenic acid/gamma-linolenic acid, and gamma-linolenic acid/oleic acid mixtures compared to before mixing. Conversely, HPLC-ESR peak heights of ethyl, 7 carboxyheptyl and pentyl radicals, which form through hydrogen atom abstraction at the carbons close to the methyl end, decreased for linoleic acid/alpha linolenic acid, linoleic acid/gamma-linolenic acid, linoleic acid/oleic acid, linoleic acid/arachidonic acid, alpha-linolenic acid/gamma-linolenic acid, and alpha-linolenic acid/oleic acid mixtures compared to before mixing. PMID- 30279619 TI - Localized hydroxyl radical generation at mmol/L and mol/L levels in water by photon irradiation. AB - The generation of localized hydroxyl radical (*OH) in aqueous samples by low linear energy transfer irradiation was investigated. Several concentrations of 5,5-dimethyl-1-pyrroline-N-oxid solution (from 0.5 to 1,680 mmol/L) were prepared and irradiated with an identical dose of X-ray or gamma-ray. The density of *OH generation in aqueous solution was evaluated by the electron paramagnetic resonance spin-trapping technique using 5,5-dimethyl-1-pyrroline-N-oxid as an electron paramagnetic resonance spin-trapping agent. The relationship between the molecular density of 5,5-dimethyl-1-pyrroline-N-oxid in the samples and the concentration of 5,5-dimethyl-1-pyrroline-N-oxid-OH generated in the irradiated samples was analyzed. Two different characteristic linear trends were observed in the 5,5-dimethyl-1-pyrroline-N-oxid-OH/5,5-dimethyl-1-pyrroline-N-oxid plots, which suggested *OH generation in two fashions, i.e., mmol/L- and mol/L-level local concentrations. The dose, dose rate, and/or the energy of photon irradiation did not affect the shapes of the 5,5-dimethyl-1-pyrroline-N-oxid OH/5,5-dimethyl-1-pyrroline-N-oxid plots. Moreover, the addition of 5 mmol/L caffeine could cancel the contribution of mmol/L-level *OH generation, leaving a trace of mol/L-level *OH generation. Thus, the localized mmol/L- and mol/L-level generations of *OH, which were independent of experimental parameters such as dose, dose rate, and/or the energy of photon of low linear energy transfer radiation, were established. PMID- 30279620 TI - Luminal plant sterol promotes brush border membrane-to-lumen cholesterol efflux in the small intestine. AB - Plant sterols are used as food additives to reduce intestinal cholesterol absorption. They also increase fecal neutral sterol (FNS) excretion irrespective of the absorption inhibition. Intestine-mediated reverse cholesterol transport, or trans-intestinal cholesterol efflux (TICE), provides the major part of the increase of FNS excretion. However, it is unknown whether plant sterols stimulate TICE or not. We have shown previously that TICE can be evaluated by brush border membrane (BBM)-to-lumen cholesterol efflux. Thus, we examined whether luminal plant sterols stimulate BBM-to-lumen cholesterol efflux in the intestinal tract or not in mice. Cannulated upper jejunum that had been pre-labeled with orally given 3H-cholesterol, was flushed and perfused to collect 3H-cholesterol effluxed back into the lumen from the BBM to estimate the efflux efficiency. Adding 0.5 mg/ml of plant sterols, but not cholesterol, in the perfusion solution doubled the efflux. Plant sterols enter the BBM and are effluxed back to the lumen rapidly, in which process cholesterol transporters in the BBM are involved. We thus speculate that phytosterols alter cholesterol flux in the BBM; thereby, increases BBM-to-lumen cholesterol efflux, resulting in the increased TICE. PMID- 30279621 TI - Dipeptidyl peptidase-4 inhibitors have adverse effects for the proliferation of human T cells. AB - Dipeptidyl peptidase-4 (DPP-4) is a critical molecule for the metabolism of incretins. In addition, DPP-4 is known as CD26, the receptor of T cells, and plays important role in activation of T cells. Recently, DPP-4 inhibitors (DPP4i) are reported to have several immunologic effects beyond glycemic control. DPP4i seem to have anti-inflammatory effects in patients with type 2 diabetes. This might be direct effects on T cells. However, the close mechanism is not clear. To evaluate the possibility, we performed ex vivo assays by using primarily human CD4+ T cells (CD4) and CD8+ T cells (CD8). We purified primary naive CD4 and CD8 from human peripheral blood. Then, we evaluated the effect of DPP4i on the proliferation of naive T cells and the cytokine production in ex vivo experiments. The proliferation of CD4 and CD8 were suppressed by adding DPP4i in a dose dependent manner. However, DPP4i did not inhibit cytokine production from CD4. It was revealed by phospho-flow that the T cell receptor (TCR) signaling was attenuated in the presence of DPP4i. Taken together, DPP4i modulated TCR signaling, which contributed to attenuate the proliferation of CD4 and CD8. DPP4i have adverse effects for the proliferation of human T cells. PMID- 30279622 TI - Short-term replacement of starch with isomaltulose enhances both insulin dependent and -independent glucose uptake in rat skeletal muscle. AB - Dietary intervention for preventing postprandial increases in glucose level by replacing high-glycemic index (GI) carbohydrates with lower-GI carbohydrate has been proposed as a strategy for treating insulin-resistant metabolic disorders such as type II diabetes. In this study, we examined the effect of short-term replacement of starch with a low-GI disaccharide, isomaltulose, on insulin action in skeletal muscle. Male Wistar rats were fed isomaltulose for 12 h during their dark cycle. In isolated epitrochlearis muscle, insulin-induced glucose uptake was greater in tissue from rats treated with isomaltulose than from those treated with starch. This insulin-sensitizing effect occurred independently of changes visceral fat mass. To determine whether this sensitization was specific to insulin stimulation, we also measured glucose uptake in response to exercise. In isolated epitrochlearis muscles from rats that performed swimming exercise, exercise-induced glucose uptake was higher in isomaltulose-treated than starch treated animals. This amplification was associated with increased phosphorylation of exercise-induced AMP-activated protein kinase. In conclusion, our results demonstrate that short-term replacement of starch with isomaltulose enhances both insulin-dependent and -independent glucose uptake in isolated skeletal muscle. This transient replacement of carbohydrate with isomaltulose, together with exercise, represents a potentially effective approach for the management of insulin resistance. PMID- 30279623 TI - Nrf2-mediated anti-oxidant effects contribute to suppression of non-alcoholic steatohepatitis-associated hepatocellular carcinoma in murine model. AB - The exact mechanisms of hepatocellular carcinoma development in non-alcoholic steatohepatitis remain unclear. In this study, we used a new class of high-fat diet, which could induce hepatocellular carcinoma development without the use of general chemical carcinogens or knockout mice. We investigated the correlation between hepatocellular carcinoma and oxidative stress/anti-oxidant effects after depletion of the gut microbiota by treatment with antibiotics. Mice fed with the steatohepatitis-inducing high-fat diet (STHD-01) for 41 weeks developed hepatocellular carcinoma. Antibiotic-treatment in mice fed with STHD-01 significantly depleted the gut microbiota and significantly ameliorated liver injury/histology. The tumor numbers of hepatocellular carcinoma were dramatically decreased by the antibiotics-treatment. We analyzed the factors involved in oxidative stress and anti-oxidant effects. Oxidative stress was elevated in mice fed with STHD-01, whereas some anti-oxidant factors were significantly elevated after antibiotics treatment. These results suggest that the gut microbiota is a key factor in improving oxidative stress induced by STHD-01 feeding. PMID- 30279624 TI - Increased oxidative stress and coenzyme Q10 deficiency in centenarians. AB - Aging populations are expanding worldwide, and the increasing requirement for nursing care has become a serious problem. Furthermore, successful aging is one of the highest priorities for individuals and societies. Centenarians are an informative cohort to study and inflammation has been found to be a key factor in predicting cognition and physical capabilities. Inflammation scores have been determined based on the levels of cytokines and C-reactive protein, however, serum antioxidants and lipid profiles have not been carefully examined. We found that the redox balance of coenzyme Q10 significantly shifted to the oxidized form and levels of strong antioxidants, such as ascorbic acid and unconjugated bilirubin, decreased significantly compared to 76-year-old controls, indicating an increased oxidative stress in centenarians. Levels of uric acid, an endogenous peroxynitrite scavenger, remained unchanged, suggesting that centenarians were experiencing moderate, chronic inflammatory conditions. Centenarians exhibited a hypocholesterolemic condition, while an increase in the ratio of free cholesterol to cholesterol esters suggests some impairment of liver function. Serum free fatty acids and monoenoic acid composition, markers of tissue oxidative damage, were significantly decreased in centenarians, indicating an impairment in the tissue repair system. Despite an elevation of the coenzyme Q10 binding protein Psap, serum total coenzyme Q10 levels decreased in centenarians. This suggests a serious deficiency of coenzyme Q10 in tissues, since tissue levels of coenzyme Q10 significantly decrease with age. Therefore, coenzyme Q10 supplementation could be beneficial for centenarians. PMID- 30279625 TI - Increased oxidative stress and renal injury in patients with sepsis. AB - Sepsis remains one of the leading causes of death in intensive care units. The early phase of sepsis is characterized by a massive formation of reactive oxygen and nitrogen species such as superoxide and nitric oxide. However, few comprehensive studies on plasma antioxidants have been reported. Increased oxidative stress was confirmed in sepsis patients (n = 18) at the time of hospitalization by a significant decrease in plasma ascorbic acid and a significant increase in the percentage of oxidized form of coenzyme Q10 in total coenzyme Q10 compared to age-matched healthy controls (n = 62). Tissue oxidative damage in patients was suggested by a significant decrease in polyunsaturated fatty acid contents and a significant increase in oleic acid contents in total free fatty acids. Thus, it is reasonable that plasma uric acid (end product of purines) would be significantly elevated. However, uric acid levels were continuously decreased during hospitalization for 7 days, indicating a continuous formation of peroxynitrite. A greater decrease in free cholesterol (FC) compared to cholesterol esters (CE) was observed. Thus, the FC/CE ratio significantly increased, suggesting deficiency of lecithin-cholesterol acyltransferase secreted from the liver. Plasma levels of prosaposin, a coenzyme Q10 binding protein, significantly decreased as compared to healthy controls. This may be correlated with renal injury in sepsis patients, since the kidney is thought to be a major secretor of prosaposin. PMID- 30279626 TI - Gender differences in LDL- and HDL-cholesterol subfractions in patients after the acute ischemic stroke and their association with oxidative stress markers. AB - The aim of our study was to examine gender differences of LDL- and HDL cholesterol subfractions in patients after the acute ischemic stroke with focus on small LDL and HDL subfractions, and their association with oxidative stress markers. In addition, we have monitored the 7-day effect of cholesterol-lowering drugs administered to patients after the acute ischemic stroke, on these subfractions. Eighty two stroke patients and 81 age matched controls were included in this study. Blood was collected from patients within 24 h after the stroke (group A) and re-examined at the 7-day follow-up (group B). We have found gender differences in LDL- and HDL-subfractions in stroke patients, lipid lowering drugs administered to acute ischemic stroke patients significantly reduced all measured parameters of lipoprotein profile. In the group A LDL1 subfraction positively correlated with activity of antioxidant enzymes (superoxide dismutase, catalase, glutathione peroxidase) indicating a protective role of this subfraction. On the contrary, small HDL subfractions positively correlated with lipoperoxide levels and negatively with trolox equivalent antioxidant capacity in plasma suggesting a negative role of these subfractions. In this work we have confirmed the hypothesis of atherogenic properties of small HDL subfractions and anti-atherogenic properties of large LDL1-subfractions. PMID- 30279627 TI - Does discontinuation of antithrombotics affect the diagnostic yield of small bowel capsule endoscopy in patients demonstrating obscure gastrointestinal bleeding? AB - A large proportion of patients demonstrating obscure gastrointestinal bleeding (OGIB) are antithrombotic users and need to undergo small bowel capsule endoscopy (SBCE). We examined the effect of discontinuation of antithrombotics on the diagnostic yield of SBCE. Additionally, we assessed predictive factors associated with positive SBCE findings. Our study included 130 patients using antithrombotics who underwent SBCE for overt OGIB. The primary endpoint was the difference in the rate of positive SBCE findings between patients who continued and those who discontinued antithrombotics. Secondary endpoints were to investigate the effect of discontinuation of antithrombotics using a propensity score analysis, and to assess predictive factors associated with a positive SBCE. Among the 73 patients who continued use of antithrombotics, 36 (49.3%) patients demonstrated positive findings, while among the 57 patients who discontinued antithrombotics, 35 (61.4%) patients showed positive findings. Rates of positive SBCE findings didn't differ between the two groups. After we performed propensity score matching, discontinuation didn't affect the rate of positive SBCE findings. The lowest hemoglobin level was the only independent predictive factor associated with positive SBCE findings. In conclusion, discontinuation of antithrombotic therapy didn't affect the diagnostic yield of SBCE in patients presenting with overt OGIB. PMID- 30279628 TI - Sex differences in associations among metabolic syndrome, obesity, related biomarkers, and colorectal adenomatous polyp risk in a Japanese population. AB - To investigate sex differences in the associations among metabolic syndrome, obesity, adipose tissue-related biomarkers, and colorectal adenomatous polyps, a cross-sectional, multicenter study was conducted on 489 consecutive individuals who underwent their first colonoscopy at 3 hospitals. Plasma concentrations of adiponectin and leptin, as well as homeostatic model assessment of insulin resistance were also evaluated. The presence and number of adenomatous polyps, including advanced adenoma, were higher in men than in women. Metabolic syndrome was a risk factor for adenomatous polyps in both sexes. Large waist circumference was an independent risk factor for adenomatous polyps in men, and high BMI and large waist circumference were risk factors for adenomatous polyps in women. Interestingly, low BMI was associated with large adenomatous polyps (>=10 mm) and advanced adenoma, and waist-hip ratio was involved in proximal adenomatous polyp development only in women. In contrast, the highest quartile of leptin concentration had a 3.67-fold increased adenomatous polyp risk compared with the lowest quartile only in men. These results indicate that regarding colorectal pathogenesis, sex differences were identified in obesity but not in metabolic syndrome. Visceral obesity and a high serum leptin level may be risk factors for colorectal adenomatous polyp development in Japanese men.

AB - The aim of this study was to assess the perioperative invasiveness of endoscopic submucosal dissection for colorectal cancer quantitatively by using energy metabolism. In fifty-three patients who underwent endoscopic submucosal dissection for colorectal cancer, resting energy expenditure using an indirect calorimeter, body weight and basal energy expenditure using the Harris-Benedict equation before and after endoscopic submucosal dissection. Resting energy expenditure/body weight and resting energy expenditure/basal energy expenditure were 19.7 +/- 2.5 kcal/kg/day and 0.96 +/- 0.12 on the day of endoscopic submucosal dissection, whereas one day after the endoscopic submucosal dissection they increased to 21.0 +/- 2.9 kcal/kg/day and 1.00 +/- 0.13 (p<0.001 and p<0.05, respectively). The stress factor on the postoperative day 1 was computed as 1.06. The increase was lower comparing with that experienced for surgery, suggesting that the perioperative invasiveness of colorectal endoscopic submucosal dissection is lower in comparison to that during surgery. Furthermore, in spite of technical difficulty, stress factor of colorectal endoscopic submucosal dissection was approximately equal to that of gastric endoscopic submucosal dissection.

PMID- 30279632 TI - Stigmellamultispicata Rociene. & Stonis, an Asian leafminer on Siberian elm, now widespread in eastern North America (Lepidoptera, Nepticulidae). AB - Stigmellamultispicata Rociene & Stonis, 2014, previously known from the single male holotype from Primorye, Russia, is reported as a new invasive species mining leaves of Siberian elm, Ulmuspumila L., in eastern North America. Both adults and leafmines have been reported from many sites as unidentified Nepticulidae since 2010. Crucial for the identification was a match of the DNA barcode of a single larva collected on Ulmuspumila in Beijing with adults from North America. The single larva constitutes a new record for China. Stigmellamultispicata is closely related to the European S.ulmivora (Fologne, 1860), feeding likewise on Ulmus, but differs in details of external morphology and genitalia, particularly in the female, where S.multispicata has a remarkable elongated narrow ovipositor, suitable for oviposition in underside hairy leaf vein axils, where all mines start. In North America S.multispicata is the only Ulmus-feeding nepticulid with green larvae. Currently the species is known from USA: Illinois, Indiana, Iowa, Maryland, Massachusetts, Minnesota, New York, Ohio, Tennessee, Wisconsin, and Canada: Ontario and Quebec. In Sagaponack, on Long Island, New York, larvae have been reported to occur en masse on Siberian elms from at least two sites. The current distribution could be reconstructed thanks also to many online photographs from observation websites. The species is redescribed, with the first descriptions of female, larva, and leafmine, and compared with S.ulmivora, which is fully redescribed. The two native North American nepticulid Ulmus leafminers, S.apicialbella (Chambers, 1873) and Ectoedemiaulmella (Braun, 1912), are diagnosed and new provincial and state records are provided. A key to linear mines on Ulmus in North America is provided. We suspect that trade of live plants through nurseries played a role in the sudden spread of this invasive species.

PMID- 30279634 TI - Chiropteran diversity in the peripheral areas of the Maduru-Oya National Park in Sri Lanka: insights for conservation and management. AB - In Sri Lanka, there are 31 species of bats distributed from lowlands to mountains. To document bat diversity and their habitat associations, 58 roosting sites in Maduru-Oya National Park periphery were surveyed. Fifteen bat species were recorded occupying 16 different roosting sites in this area. Among all the species recorded, Rhinolophusrouxii was the most abundant species per roosting site whereas Kerivoulapicta was the least abundant. A road-kill specimen similar to genus Phoniscus was found during the survey, a genus so far only documented in Southeast Asia and Australasia. Although our study area provided habitats for a diverse chiropteran community, the colony size per roost was remarkably low. Although our study area is supposedly a part of the park's buffer zone, many anthropogenic activities are threatening the bat community: felling large trees, slash-and-burn agriculture, excessive use of agrochemicals, vengeful killing, and subsidized predation. We strongly recommend adoption of wildlife-friendly sustainable land management practices in the buffer zone such as forest gardening, agroforestry (alley cropping, mixed-cropping), and integrated farming. Bat conservation in this region should take a landscape-scale conservation approach which includes Maduru-Oya National Park and other surrounding protected areas into a regional conservation network. Extents of undisturbed wilderness are dramatically declining in Sri Lanka; thus, future conservation efforts must be retrofitted into anthropocentric multiuse landscapes and novel ecosystems like areas surrounding Maduru-Oya National Park. PMID- 30279635 TI - Sample Entropy on Multidistance Signal Level Difference for Epileptic EEG Classification. AB - Epilepsy is a disorder of the brain's nerves as a result of excessive brain cell activity. It is generally characterized by the recurrent unprovoked seizures. This neurological abnormality can be detected and evaluated using Electroencephalogram (EEG) signal. Many algorithms have been applied to achieve high performance for the EEG classification of epileptic. However, the complexity and randomness of EEG signals become a challenge to researchers in applying the appropriate algorithms. In this research, sample entropy on Multidistance Signal Level Difference (MSLD) was applied to obtain the characteristic of EEG signals, especially towards the epilepsy patients. The test was performed on three classes of EEG data: EEG signals of epilepsy patient in ictal (seizure), interictal conditions (occurring between seizures) and normal EEG signals from healthy subjects with a closed eye condition. In this study, classification and verification were done using the Support Vector Machine (SVM) method. Through the 5-fold cross-validation, experimental results showed the highest accuracy of 97.7%.

PMID- 30279637 TI - Serial electron crystallography for structure determination and phase analysis of nanocrystalline materials. AB - Serial electron crystallography has been developed as a fully automated method to collect diffraction data on polycrystalline materials using a transmission electron microscope. This enables useful data to be collected on materials that are sensitive to the electron beam and thus difficult to measure using the conventional methods that require long exposure of the same crystal. The data collection strategy combines goniometer translation with electron beam shift, which allows the entire sample stage to be probed. At each position of the goniometer, the locations of the crystals are identified using image recognition techniques. Diffraction data are then collected on each crystal using a quasi parallel focused beam with a predefined size (usually 300-500 nm). It is shown that with a fast and sensitive Timepix hybrid pixel area detector it is possible to collect diffraction data of up to 3500 crystals per hour. These data can be indexed using a brute-force forward-projection algorithm. Results from several test samples show that 100-200 frames are enough for structure determination using direct methods or dual-space methods. The large number of crystals examined enables quantitative phase analysis and automatic screening of materials for known and unknown phases. PMID- 30279638 TI - Glassy carbon, NIST Standard Reference Material (SRM 3600): hydrogen content, neutron vibrational density of states and heat capacity. AB - Commercial glassy carbon plates being used as absolute intensity calibration standards in small-angle X-ray scattering applications (NIST SRM 3600) have been characterized in several recent publications. This contribution adds to the characterization by measuring the hydrogen content of a plate to be (4.8 +/- 0.2) * 10-4 (mol H)/(mol C), and by measuring the vibrational spectrum by neutron inelastic scattering. The spectrum bears a strong resemblance to published measurements on graphite, allowing the identification of several spectral features. The measured spectrum is used to calculate the heat capacity of low hydrogen-content glassy carbon for comparison with measurements reported here from 20 to 295 K.

These planar defects were rectangular with dimensions of 50-150 um, and the X-ray topography analysis revealed that they were stacking faults (SFs) enclosed by a single partial dislocation loop on the plane. The SF formation was found to be supported by a unique structural feature of the plane as a slip plane; the plane consists of close-packed octahedral Ga and O layers, allowing slips to form SFs. Vacancy arrays along the b axis in the octahedral Ga layer reduce the self-energy of the edge component in the partial dislocation extending along the b axis. It is speculated that the SFs occur during the crystal growth process for unknown reasons and then recover owing to elastic instability after initially increasing in size as crystal growth proceeds. Based on this analysis, a structural model for the SFs is proposed. PMID- 30279640 TI - Model-free classification of X-ray scattering signals applied to image segmentation. AB - In most cases, the analysis of small-angle and wide-angle X-ray scattering (SAXS and WAXS, respectively) requires a theoretical model to describe the sample's scattering, complicating the interpretation of the scattering resulting from complex heterogeneous samples. This is the reason why, in general, the analysis of a large number of scattering patterns, such as are generated by time-resolved and scanning methods, remains challenging. Here, a model-free classification method to separate SAXS/WAXS signals on the basis of their inflection points is introduced and demonstrated. This article focuses on the segmentation of scanning SAXS/WAXS maps for which each pixel corresponds to an azimuthally integrated scattering curve. In such a way, the sample composition distribution can be segmented through signal classification without applying a model or previous sample knowledge. Dimensionality reduction and clustering algorithms are employed to classify SAXS/WAXS signals according to their similarity. The number of clusters, i.e. the main sample regions detected by SAXS/WAXS signal similarity, is automatically estimated. From each cluster, a main representative SAXS/WAXS signal is extracted to uncover the spatial distribution of the mixtures of phases that form the sample. As examples of applications, a mudrock sample and two breast tissue lesions are segmented.

AB - The installation of multi-axis goniometers such as the ESRF/EMBL miniKappa goniometer system has allowed the increased use of sample reorientation in macromolecular crystallography. Old and newly appearing data collection methods require precision and accuracy in crystal reorientation. The proper use of such multi-axis systems has necessitated the development of rapid and easy to perform methods for establishing and evaluating device calibration. A new diffraction based method meeting these criteria has been developed for the calibration of the motors responsible for rotational motion. This method takes advantage of crystal symmetry by comparing the orientations of a sample rotated about a given axis and checking that the magnitude of the real rotation fits the calculated angle between these two orientations. Hence, the accuracy and precision of rotational motion can be assessed. This rotation calibration procedure has been performed on several beamlines at the ESRF and other synchrotrons. Some resulting data are presented here for reference. PMID- 30279642 TI - Effects of multiple scattering encountered for various small-angle scattering model functions. AB - In small-angle scattering theory and data modeling, it is generally assumed that each scattered ray - photon or neutron - is only scattered once on its path through the sample. This assumption greatly simplifies the interpretation of the data and is valid in many cases. However, it breaks down under conditions of high scattering power, increasing with sample concentration, scattering contrast, sample path length and ray wavelength. For samples with a significant scattering power, disregarding multiple scattering effects can lead to erroneous conclusions on the structure of the investigated sample. In this paper, the impact of multiple scattering effects on different types of scattering pattern are determined, and methods for assessing and addressing them are discussed, including the general implementation of multiple scattering effects in structural model fits. The modification of scattering patterns by multiple scattering is determined for the sphere scattering function and the Gaussian function, as well as for different Sabine-type functions, including the Debye-Andersen-Brumberger (DAB) model and the Lorentzian scattering function. The calculations are performed using the semi-analytical convolution method developed by Schelten & Schmatz [J. Appl. Cryst. (1980 ?). 13, 385-390], facilitated by analytical expressions for intermediate functions, and checked with Monte Carlo simulations. The results show how a difference in the shape of the scattering function plotted versus momentum transfer q results in different multiple scattering effects at low q, where information on the particle mass and radius of gyration is contained.

AB - Background: This complex environmental heterogeneity coupled with the long standing history offers scenario suitable for and favoring the evolution and existence of variation of morphological traits. Methods: In this study, we measured 10 morphological traits of 310 Cynodon dactylon individuals sampled at 16 different locations along latitudinal gradients between 22 degrees 35'N and 36 degrees 18'N to reveal phenotypic plasticity influenced by latitude. In addition, the relationships between morphological variation and soil nutrient and climate factors were analyzed. Results: Analysis of variance, divesity examination and Mantel correlation test detected a significant effect of latitude on morphological traits. Cluster analysis and principal component analysis clearly separated the selected populations into four groups according to latitude. Larger morphological sizes of C. dactylon appeared at the low- and high-latitude regions. Correlation analysis indicated that high morphological variations were significantly correlated with climate factors and soil nutrient. Conclusion: This study suggests morphological variation of wild bermudagrass is greatly influenced by latitude as well as soil and climate, which could be useful resources for genetic studies and evolution. PMID- 30279644 TI - Long-read sequencing identified a causal structural variant in an exome-negative case and enabled preimplantation genetic diagnosis. AB - Background: For a proportion of individuals judged clinically to have a recessive Mendelian disease, only one heterozygous pathogenic variant can be found from clinical whole exome sequencing (WES), posing a challenge to genetic diagnosis and genetic counseling. One possible reason is the limited ability to detect disease causal structural variants (SVs) from short reads sequencing technologies. Long reads sequencing can produce longer reads (typically 1000 bp or longer), therefore offering greatly improved ability to detect SVs that may be missed by short-read sequencing. Results: Here we describe a case study, where WES identified only one heterozygous pathogenic variant for an individual suspected to have glycogen storage disease type Ia (GSD-Ia), which is an autosomal recessive disease caused by bi-allelic mutations in the G6PC gene. Through Nanopore long-read whole-genome sequencing, we identified a 7.1 kb deletion covering two exons on the other allele, suggesting that complex structural variants (SVs) may explain a fraction of cases when the second pathogenic allele is missing from WES on recessive diseases. Both breakpoints of the deletion are within Alu elements, and we designed Sanger sequencing and quantitative PCR assays based on the breakpoints for preimplantation genetic diagnosis (PGD) for the family planning on another child. Four embryos were obtained after in vitro fertilization (IVF), and an embryo without deletion in G6PC was transplanted after PGD and was confirmed by prenatal diagnosis, postnatal diagnosis, and subsequent lack of disease symptoms after birth. Conclusions: In summary, we present one of the first examples of using long-read sequencing to identify causal yet complex SVs in exome-negative patients, which subsequently enabled successful personalized PGD. PMID- 30279645 TI - Variable Neural Contributions to Explicit and Implicit Learning During Visuomotor Adaptation. AB - We routinely make fine motor adjustments to maintain optimal motor performance. These adaptations have been attributed to both implicit, error-based mechanisms, and explicit, strategy-based mechanisms. However, little is known about the neural basis of implicit vs. explicit learning. Here, we aimed to use anodal transcranial direct current stimulation (tDCS) to probe the relationship between different brain regions and learning mechanisms during a visuomotor adaptation task in humans. We hypothesized that anodal tDCS over the cerebellum (CB) should increase implicit learning while anodal tDCS over the dorsolateral prefrontal cortex (dlPFC), a region associated with higher-level cognition, should facilitate explicit learning. Using a horizontal visuomotor adaptation task that measures explicit/implicit contributions to learning (Taylor et al., 2014), we found that dlPFC stimulation significantly improved performance compared to the other groups, and weakly increased explicit learning. However, CB stimulation had no effects on either target error or implicit learning. Previous work showed variable CB stimulation effects only on a vertical visuomotor adaptation task (Jalali et al., 2017), so in Experiment 2, we conducted the same study using a vertical context to see if we could find effects of CB stimulation. We found only weak effects of CB stimulation on target error and implicit learning, and now the dlPFC effect did not replicate. To resolve this discrepancy, in Experiment 3, we examined the effect of context (vertical vs. horizontal) on implicit and explicit contributions and found that individuals performed significantly worse and used greater implicit learning in the vertical screen condition compared to the horizontal screen condition. Across all experiments, however, there was high inter-individual variability, with strong influences of a few individuals, suggesting that these effects are not consistent across individuals. Overall, this work provides preliminary support for the idea that different neural regions can be engaged to improve visuomotor adaptation, but shows that each region's effects are highly context-dependent and not clearly dissociable from one another. This holds implications especially in neurorehabilitation, where an intact neural region could be engaged to potentially compensate if another region is impaired. Future work should examine factors influencing interindividual variability during these processes. PMID- 30279646 TI - Inhibition of DNA Methylation With Zebularine Alters Lipopolysaccharide-Induced Sickness Behavior and Neuroinflammation in Mice. AB - Activity of DNA methyltransferases (DNMTs), the enzymes that catalyze DNA methylation, is dynamically regulated in the brain. DNMT inhibitors alter DNA methylation globally in the brain and at individual neural plasticity-associated genes, but how DNMT inhibitors centrally influence lipopolysaccharide (LPS) induced neuroinflammation is not known. We investigated whether the DMNT inhibitor, zebularine, would alter sickness behavior, DNA methylation of the Il 1beta promoter and expression of inflammatory genes in hippocampus and microglia. Contrary to our hypothesis that zebularine may exaggerate LPS-induced sickness response and neuroinflammation, adult mice treated with an intracerebroventricular (ICV) injection of zebularine prior to LPS had surprisingly faster recovery of burrowing behavior compared to mice treated with LPS. Further, genes of inflammatory markers, epigenetic regulators, and the microglial sensory apparatus (i.e., the sensome) were differentially expressed by zebularine alone or in combination with LPS. Bisulfite pyrosequencing revealed that ICV zebularine led to decreased DNA methylation of two CpG sites near the Il 1beta proximal promoter alone or in combination with LPS. Zebularine treated mice still exhibited decreased DNA methylation 48 h after treatment when LPS-induced sickness behavior as well as hippocampal and microglial gene expression were similar to control mice. Taken together, these data suggest that decreased DNA methylation, specifically of the Il-1beta promoter region, with a DNMT inhibitor in the brain disrupts molecular mechanisms of neuroinflammation. PMID- 30279647 TI - Presynaptic mGlu1 Receptors Control GABAB Receptors in an Antagonist-Like Manner in Mouse Cortical GABAergic and Glutamatergic Nerve Endings. AB - Mouse cortical GABAergic synaptosomes possess presynaptic inhibitory GABAB autoreceptors. Accordingly, (+/-)baclofen (3 MUM) inhibits in a CGP53423 sensitive manner the 12 mM KCl-evoked release of preloaded [3H]GABA. Differently, the existence of presynaptic release-regulating metabotropic glutamate type 1 (mGlu1) heteroreceptors in these terminals is still matter of discussion, although confocal microscopy unveiled the existence of mGlu1alpha with GABAB1 or GABAB2 proteins in cortical VGAT-positive synaptosomes. The group I mGlu agonist 3,5-DHPG failed to modify on its own the 12 mM KCl-evoked [3H]GABA exocytosis from cortical nerve endings, but, when added concomitantly to the GABAB agonist, it significantly reduced the 3 MUM (+/-)baclofen-induced inhibition of [3H]GABA exocytosis. Conversely, the mGlu1 antagonist LY367385 (0.03-1 MUM), inactive on its own on GABA exocytosis, amplified the 3 MUM (+/-)baclofen-induced inhibition of [3H]GABA overflow. The ( +/- )baclofen-induced inhibition of [3H]GABA exocytosis was more pronounced in cortical synaptosomes from Grm1crv4/crv4 mice, which bear a spontaneous mutation of the Grm1 gene leading to the functional inactivation of the mGlu1 receptor. Inasmuch, the expression of GABAB2 receptor protein in cortical synaptosomal lysates from Grm1crv4/crv4 mice was increased when compared to controls. Altogether, these observations seem best interpreted by assuming that mGlu1 coexist with GABAB receptors in GABAergic cortical synaptosomes, where they control GABA receptors in an antagonist-like manner. We then asked whether the mGlu1-mediated control of GABAB receptors is restricted to GABAergic terminals, or if it occurs also in other subpopulations of nerve endings. Release-regulating GABAB receptors also exist in glutamatergic nerve endings. (+/-)baclofen (1 MUM) diminished the 12 mM KCl-evoked [3H]D-aspartate overflow. Also in these terminals, the concomitant presence of 1 MUM LY367385, inactive on its own, significantly amplified the inhibitory effect exerted by (+/ )baclofen on [3H]D-aspartate exocytosis. Confocal microscopy confirmed the colocalization of mGlu1 with GABAB1 and GABAB2 labeling in vesicular glutamate type1 transporter-positive particles. Our results support the conclusion that mGlu1 receptors modulate in an antagonist-like manner presynaptic release regulating GABAB receptors. This receptor-receptor interaction could be neuroprotective in central disease typified by hyperglutamatergicity. PMID- 30279648 TI - Drug Screening Identifies Sigma-1-Receptor as a Target for the Therapy of VWM Leukodystrophy. AB - Vanishing white matter (VWM) disease is an autosomal genetic leukodystrophy caused by mutations in subunits of eukaryotic translation initiation factor 2B (eIF2B). The clinical symptoms exhibit progressive loss of white matter in both hemispheres of the brain, accompanied by motor functions deterioration, neurological deficits, and early death. To date there is no treatment for VWM disease. The aim of this work was to expedite rational development of a therapeutic opportunity. Our approach was to design a computer-aided strategy for an efficient and reliable screening of drug-like molecules; and to use primary cultures of fibroblasts isolated from the Eif2b5R132H/R132H VWM mouse model for screening. The abnormal mitochondria content phenotype of the mutant cells was chosen as a read-out for a simple cell-based fluorescent assay to assess the effect of the tested compounds. We obtained a hit rate of 0.04% (20 hits out of 50,000 compounds from the selected library). All primary hits decreased mitochondria content and brought it closer to WT levels. Structural similarities between our primary hits and other compounds with known targets allowed the identification of three putative cellular pathways/targets: 11beta-hydroxysteroid dehydrogenase type 1, Sonic hedgehog (Shh), and Sigma-1-Receptor (S1R). In addition to initial experimental indication of Shh pathway impairment in VWM mouse brains, the current study provides evidence that S1R is a relevant target for pharmaceutical intervention for potential treatment of the disease. Specifically, we found lower expression level of S1R protein in fibroblasts, astrocytes, and whole brains isolated from Eif2b5R132H/R132H compared to WT mice, and confirmed that one of the hits is a direct binder of S1R, acting as agonist. Furthermore, we provide evidence that treatment of mutant mouse fibroblasts and astrocytes with various S1R agonists corrects the functional impairments of their mitochondria and prevents their need to increase their mitochondria content for compensation purposes. Moreover, S1R activation enhances the survival rate of mutant cells under ER stress conditions, bringing it to WT levels. This study marks S1R as a target for drug development toward treatment of VWM disease. Moreover, it further establishes the important connection between white matter well-being and S1R-mediated proper mitochondria/ER function. PMID- 30279650 TI - Spontaneous Neural Activity in the Superior Temporal Gyrus Recapitulates Tuning for Speech Features. AB - Background: Numerous studies have demonstrated that individuals exhibit structured neural activity in many brain regions during rest that is also observed during different tasks, however it is still not clear whether and how resting state activity patterns may relate to underlying tuning for specific stimuli. In the posterior superior temporal gyrus (STG), distinct neural activity patterns are observed during the perception of specific linguistic speech features. We hypothesized that spontaneous resting-state neural dynamics of the STG would be structured to reflect its role in speech perception, exhibiting an organization along speech features as seen during speech perception. Methods: Human cortical local field potentials were recorded from the superior temporal gyrus (STG) in 8 patients undergoing surgical treatment of epilepsy. Signals were recorded during speech perception and rest. Patterns of neural activity (high gamma power: 70-150 Hz) during rest, extracted with spatiotemporal principal component analysis, were compared to spatiotemporal neural responses to speech features during perception. Hierarchical clustering was applied to look for patterns in rest that corresponded to speech feature tuning. Results: Significant correlations were found between neural responses to speech features (sentence onsets, consonants, and vowels) and the spontaneous neural activity in the STG. Across subjects, these correlations clustered into five groups, demonstrating tuning for speech features-most robustly for acoustic onsets. These correlations were not seen in other brain areas, or during motor and spectrally-rotated speech control tasks. Conclusions: In this study, we present evidence that the RS structure of STG activity robustly recapitulates its stimulus-evoked response to acoustic onsets. Further, secondary patterns in RS activity appear to correlate with stimulus-evoked responses to speech features. The role of these spontaneous spatiotemporal activity patterns remains to be elucidated. PMID- 30279649 TI - Eight Weddings and Six Funerals: An fMRI Study on Autobiographical Memories. AB - "Autobiographical memory" (AM) refers to remote memories from one's own life. Previous neuroimaging studies have highlighted that voluntary retrieval processes from AM involve different forms of memory and cognitive functions. Thus, a complex and widespread brain functional network has been found to support AM. The present functional magnetic resonance imaging (fMRI) study used a multivariate approach to determine whether neural activity within the AM circuit would recognize memories of real autobiographical events, and to evaluate individual differences in the recruitment of this network. Fourteen right-handed females took part in the study. During scanning, subjects were presented with sentences representing a detail of a highly emotional real event (positive or negative) and were asked to indicate whether the sentence described something that had or had not really happened to them. Group analysis showed a set of cortical areas able to discriminate the truthfulness of the recalled events: medial prefrontal cortex, posterior cingulate/retrosplenial cortex, precuneus, bilateral angular, superior frontal gyri, and early visual cortical areas. Single-subject results showed that the decoding occurred at different time points. No differences were found between recalling a positive or a negative event. Our results show that the entire AM network is engaged in monitoring the veracity of AMs. This process is not affected by the emotional valence of the experience but rather by individual differences in cognitive strategies used to retrieve AMs. PMID- 30279651 TI - Altered Functional Connectivity in Resting State Networks in Tourette's Disorder. AB - Introduction: Brain regions are anatomically and functionally interconnected in order to facilitate important functions like cognition and movement. It remains incompletely understood how brain connectivity contributes to the pathophysiology of Tourette's disorder (TD). By using resting-state functional MRI, we aimed to identify alterations in the default mode network (DMN), frontal-parietal network (FPN), sensori-motor network (SMN), and salience network (SN) in TD compared with healthy control (HC) subjects. Method: In 23 adult TD patients and 22 HC, 3T-MRI resting-state scans were obtained. Independent component analysis was performed comparing TD and HC to investigate connectivity patterns within and between resting-state networks. Results: TD patients showed higher involvement of the dorsal medial prefrontal cortex in the connectivity of the DMN and less involvement of the inferior parietal cortex in the connectivity of the FPN when compared to HC. Moreover, TD patients showed a stronger coupling between DMN and left FPN than HC. Finally, in TD patients, functional connectivity within DMN correlated negatively with tic severity. Conclusion: We tentatively interpret the increased functional connectivity within DMN in TD patients as compensatory to the lower functional connectivity within left FPN. The stronger coupling between DMN and left FPN, together with the finding that higher DMN intrinsic connectivity is associated with lower tic severity would indicate that DMN is recruited to exert motor inhibition.

PMID- 30279652 TI - Common and Unique Neural Systems Underlying the Working Memory Maintenance of Emotional vs. Bodily Reactions to Affective Stimuli: The Moderating Role of Trait Emotional Awareness. AB - Many leading theories suggest that the neural processes underlying the experience of one's own emotional reactions partially overlap with those underlying bodily perception (i.e., interoception, somatosensation, and proprioception). However, the goal-directed maintenance of one's own emotions in working memory (EWM) has not yet been compared to WM maintenance of one's own bodily reactions (BWM). In this study, we contrasted WM maintenance of emotional vs. bodily reactions to affective stimuli in 26 healthy individuals while they underwent functional magnetic resonance imaging. Specifically, we examined the a priori hypothesis that individual differences in trait emotional awareness (tEA) would lead to greater differences between these two WM conditions within medial prefrontal cortex (MPFC). We observed that MPFC activation during EWM (relative to BWM) was positively associated with tEA. Whole-brain analyses otherwise suggested considerable similarity in the neural activation patterns associated with EWM and BWM. In conjunction with previous literature, our findings not only support a central role of body state representation/maintenance in EWM, but also suggest greater engagement of MPFC-mediated conceptualization processes during EWM in those with higher tEA. PMID- 30279653 TI - Optimal Localist and Distributed Coding of Spatiotemporal Spike Patterns Through STDP and Coincidence Detection. AB - Repeating spatiotemporal spike patterns exist and carry information. Here we investigated how a single spiking neuron can optimally respond to one given pattern (localist coding), or to either one of several patterns (distributed coding, i.e., the neuron's response is ambiguous but the identity of the pattern could be inferred from the response of multiple neurons), but not to random inputs. To do so, we extended a theory developed in a previous paper (Masquelier, 2017), which was limited to localist coding. More specifically, we computed analytically the signal-to-noise ratio (SNR) of a multi-pattern-detector neuron, using a threshold-free leaky integrate-and-fire (LIF) neuron model with non plastic unitary synapses and homogeneous Poisson inputs. Surprisingly, when increasing the number of patterns, the SNR decreases slowly, and remains acceptable for several tens of independent patterns. In addition, we investigated whether spike-timing-dependent plasticity (STDP) could enable a neuron to reach the theoretical optimal SNR. To this aim, we simulated a LIF equipped with STDP, and repeatedly exposed it to multiple input spike patterns, embedded in equally dense Poisson spike trains. The LIF progressively became selective to every repeating pattern with no supervision, and stopped discharging during the Poisson spike trains. Furthermore, tuning certain STDP parameters, the resulting pattern detectors were optimal. Tens of independent patterns could be learned by a single neuron using a low adaptive threshold, in contrast with previous studies, in which higher thresholds led to localist coding only. Taken together these results suggest that coincidence detection and STDP are powerful mechanisms, fully compatible with distributed coding. Yet we acknowledge that our theory is limited to single neurons, and thus also applies to feed-forward networks, but not to recurrent ones. PMID- 30279655 TI - Cognitive Reserve Factors in a Developing Country: Education and Occupational Attainment Lower the Risk of Dementia in a Sample of Lebanese Older Adults. AB - Background: Dementia secondary to neurodegenerative diseases is prevalent among older adults and leads to social, psychological and economic burden on patients, caregivers and the community as a whole. Cognitive reserve factors such as education, and mental stimulation among others were hypothesized to contribute to the resilience against age-related cognitive impairment. Educational attainment, occupation complexity, physical activity, and leisure activity are explored in the context of protecting the older adults' cognitive function. We investigated the cognitive reserve effect on dementia, cognitive decline and impairment, and global cognitive function. Methods: This study is a secondary analysis of data from a cross-sectional, community-based cohort study that aimed at investigating factors associated with dementia and their prevalence. The sample was of 508 community based older adults in Lebanon, aged 65 years and above in addition to 502 informants designated by these older adults. Older adults and informants answered structured questionnaires administered by interviewers, as well as a physical assessment and a neurological examination. Older adults were diagnosed for dementia. Global cognitive function, depression, and cognitive decline were assessed. Results: Older adults with dementia had lower levels of education, and attained lower occupational complexity. Factors such as high education, complex occupation attainment, and leisure activity, significantly predicted better global cognitive function. An older adult who attained high education levels or high complexity level occupation was 7.1 or 4.6 times more likely to have better global cognitive function than another who attained lower education or complexity level occupation respectively. Conclusion: These results suggest that cognitive reserve factors ought to be taken into consideration clinically during the course of dementia diagnosis and when initiating community-based preventive strategies. PMID- 30279656 TI - Cerebral Blood Flow and Cognitive Functioning in a Community-Based, Multi-Ethnic Cohort: The SABRE Study. AB - Introduction: Lower cerebral blood flow (CBF) is associated with cardiovascular disease and vascular risk factors, and is increasingly acknowledged as an important contributor to cognitive decline and dementia. In this cross-sectional study, we examined the association between CBF and cognitive functioning in a community-based, multi-ethnic cohort. Methods: From the SABRE (Southall and Brent Revisited) study, we included 214 European, 151 South Asian and 87 African Caribbean participants (71 +/- 5 years; 39%F). We used 3T pseudo-continuous arterial spin labeling to estimate whole-brain, hematocrit corrected CBF. We measured global cognition and three cognitive domains (memory, executive functioning/attention and language) with a neuropsychological test battery. Associations were investigated using linear regression analyses, adjusted for demographic variables, vascular risk factors and MRI measures. Results: Across groups, we found an association between higher CBF and better performance on executive functioning/attention (standardized beta [stbeta] = 0.11, p < 0.05). Stratification for ethnicity showed associations between higher CBF and better performance on memory and executive functioning/attention in the white European group (stbeta = 0.14; p < 0.05 and stbeta = 0.18; p < 0.01 respectively), associations were weaker in the South Asian and African Caribbean groups. Conclusions: In a multi-ethnic community-based cohort we showed modest associations between CBF and cognitive functioning. In particular, we found an association between higher CBF and better performance on executive functioning/attention and memory in the white European group. The observations are consistent with the proposed role of cerebral hemodynamics in cognitive decline. PMID- 30279657 TI - The Influence of Universal Health Coverage on Life Expectancy at Birth (LEAB) and Healthy Life Expectancy (HALE): A Multi-Country Cross-Sectional Study. AB - Background: There are substantial differences in long term health outcomes across countries, particularly in terms of both life expectancy at birth (LEAB) and healthy life expectancy (HALE). Socio-economic status, disease prevention approaches, life style and health financing systems all influence long-term health goals such as life expectancy. Within this context, universal health coverage (UHC) is expected to influence life expectancy as a comprehensive health policy. The aim of the study is to investigate this relationship between Universal Health Coverage (UHC) and life expectancy. Method: A multi-country cross-sectional study was performed drawing on different sources of data (World Health Organization, UNDP-Education and World Bank) from 193 UN member countries, applying administrative record linkage theory. Descriptive statistics, t-tests, Pearson correlations, hierarchical linear regressions were utilized as appropriate. Result: Global average healthy life years was shown to be 61.34 +/- 8.40 and life expectancy at birth was 70.00 +/- 9.3. Standardized coefficients from regression analysis found UHC (0.34), child vaccination (Diphtheria Pertussis Tetanus-3: 0.17) and sanitation coverage (0.31) were associated with significantly increased life expectancy at birth. In contrast, population growth was associated with a decrease (0.29). Likewise, unit increases in child vaccination (DPT 3), sanitation and UHC would increase healthy life expectancy considerably (0.18, 0.31, and 0.40 respectively), whereas the same for population growth reduces healthy life expectancy by 0.28. Conclusion: Universal Health Coverage (UHC) is a comprehensive health system approach that facilitates a wide range of health services and significantly improves the life expectancy at birth and healthy life expectancy. This study suggests that specific programs to achieve UHC should be considered for countries that have not seen sufficient gains in life expectancy as part of the wider push to achieve the Sustainable Development Goal (SDG). PMID- 30279658 TI - Propensity Score-Based Approaches in High Dimension for Pharmacovigilance Signal Detection: an Empirical Comparison on the French Spontaneous Reporting Database. AB - Classical methods used for signal detection in pharmacovigilance rely on disproportionality analysis of counts aggregating spontaneous reports of a given adverse drug reaction. In recent years, alternative methods have been proposed to analyze individual spontaneous reports such as penalized multiple logistic regression approaches. These approaches address some well-known biases resulting from disproportionality methods. However, while penalization accounts for computational constraints due to high-dimensional data, it raises the issue of determining the regularization parameter and eventually that of an error controlling decision rule. We present a new automated signal detection strategy for pharmacovigilance systems, based on propensity scores (PS) in high dimension. PSs are increasingly used to assess a given association with high-dimensional observational healthcare databases in accounting for confusion bias. Our main aim was to develop a method having the same advantages as multiple regression approaches in dealing with bias, while relying on the statistical multiple comparison framework as regards decision thresholds, by considering false discovery rate (FDR)-based decision rules. We investigate four PS estimation methods in high dimension: a gradient tree boosting (GTB) algorithm from machine learning and three variable selection algorithms. For each (drug, adverse event) pair, the PS is then applied as adjustment covariate or by using two kinds of weighting: inverse proportional treatment weighting and matching weights. The different versions of the new approach were compared to a univariate approach, which is a disproportionality method, and to two penalized multiple logistic regression approaches, directly applied on spontaneous reporting data. Performance was assessed through an empirical comparative study conducted on a reference signal set in the French national pharmacovigilance database (2000 2016) that was recently proposed for drug-induced liver injury. Multiple regression approaches performed better in detecting true positives and false positives. Nonetheless, the performances of the PS-based methods using matching weights was very similar to that of multiple regression and better than with the univariate approach. In addition to being able to control FDR statistical errors, the proposed PS-based strategy is an interesting alternative to multiple regression approaches. PMID- 30279659 TI - Bystander Effects of Hypoxia-Activated Prodrugs: Agent-Based Modeling Using Three Dimensional Cell Cultures. AB - Intra-tumor heterogeneity represents a major barrier to anti-cancer therapies. One strategy to minimize this limitation relies on bystander effects via diffusion of cytotoxins from targeted cells. Hypoxia-activated prodrugs (HAPs) have the potential to exploit hypoxia in this way, but robust methods for measuring bystander effects are lacking. The objective of this study is to develop experimental models (monolayer, multilayer, and multicellular spheroid co cultures) comprising 'activator' cells with high expression of prodrug-activating reductases and reductase-deficient 'target' cells, and to couple these with agent based models (ABMs) that describe diffusion and reaction of prodrugs and their active metabolites, and killing probability for each cell. HCT116 cells were engineered as activators by overexpressing P450 oxidoreductase (POR) and as targets by knockout of POR, with fluorescent protein and antibiotic resistance markers to enable their quantitation in co-cultures. We investigated two HAPs with very different pharmacology: SN30000 is metabolized to DNA-breaking free radicals under hypoxia, while the dinitrobenzamide PR104A generates DNA crosslinking nitrogen mustard metabolites. In anoxic spheroid co-cultures, increasing the proportion of activator cells decreased killing of both activators and targets by SN30000. An ABM parameterized by measuring SN30000 cytotoxicity in monolayers and diffusion-reaction in multilayers accurately predicted SN30000 activity in spheroids, demonstrating the lack of bystander effects and that rapid metabolic consumption of SN30000 inhibited prodrug penetration. In contrast, killing of targets by PR104A in anoxic spheroids was markedly increased by activators, demonstrating that a bystander effect more than compensates any penetration limitation. However, the ABM based on the well-studied hydroxylamine and amine metabolites of PR104A did not fit the cell survival data, indicating a need to reassess its cellular pharmacology. Characterization of extracellular metabolites of PR104A in anoxic cultures identified more stable, lipophilic, activated dichloro mustards with greater tissue diffusion distances. Including these metabolites explicitly in the ABM provided a good description of activator and target cell killing by PR104A in spheroids. This study represents the most direct demonstration of a hypoxic bystander effect for PR104A to date, and demonstrates the power of combining mathematical modeling of pharmacokinetics/pharmacodynamics with multicellular culture models to dissect bystander effects of targeted drug carriers. PMID- 30279661 TI - Dietary Lipids Affect the Onset of Hibernation in the Garden Dormouse (Eliomys quercinus): Implications for Cardiac Function. AB - Dietary lipids strongly influence patterns of hibernation in heterotherms. Increased dietary uptake of n-6 polyunsaturated fatty acids (PUFAs), particularly of linoleic acid (LA, C18:2 n-6), enables animals to reach lower body temperatures (Tb), lengthens torpor bout duration, and results in lower energy expenditure during hibernation. Conversely, dietary n-3 PUFA impacts negatively on hibernation performance. PUFA in surrounding phospholipids (PLs) presumably modulate the temperature-dependent activity of the sarcoplasmic reticulum (SR) Ca2+ ATPase 2 (SERCA2) and thus determine the threshold Tb still allowing proper heart function during torpor. We tested the effect of diets enriched with 10% of either corn oil ("CO," high n-6 PUFA, e.g., LA) or menhaden oil ["MO," long-chain n-3 PUFA, e.g., docosahexaenoic acid (DHA)] on hibernation performance and SERCA2 activity levels during torpor in garden dormice, an insectivorous, fat-storing hibernator. Prior to hibernation, individuals fed the MO diet showed an almost nine-times higher DHA levels and 30% lower LA proportions in white adipose tissue (WAT), reflecting the fatty acid composition of SR membranes, compared to CO-diet fed animals. When fed the MO diet, dormice significantly delayed their mean onset of hibernation by almost 4 days (range: 0-12 days), compared with CO-diet fed animals. Hibernation onset correlated positively with WAT-DHA levels and negatively with WAT-LA proportions prior to hibernation. Subsequently, hibernating patterns were similar between the two dietary groups, despite a significant difference in WAT-LA but not in WAT-DHA levels in mid-hibernation. SR PL fatty acid composition and SERCA2 activity were identical in torpid individuals from the two dietary groups in mid-hibernation. In line with our previous findings on Syrian hamsters, a granivorous, food-storing hibernator, SERCA2 activity correlated positively with LA and negatively with DHA levels of SR-PL in torpid dormice, although SERCA2 activity was about three-times higher in garden dormice than in Syrian hamsters at similar PL-DHA proportions. Similarly, minimal Tb during torpor decreased as SERCA2 activity increased. We conclude that: (1) fatty acid composition of SR membranes modulates cardiac SERCA2 activity, hence determining the minimum Tb tolerated by hibernators, and (2) high DHA levels prevent hibernators from entering into torpor, but the critical levels differ substantially between species.

AB - While isolation of the pulmonary veins is firmly established as effective treatment for the majority of paroxysmal atrial fibrillation (AF) patients, there is recognition that patients with persistent AF have substrate for perpetuation of arrhythmia existing outside of the pulmonary veins. Various computational approaches have been used to identify targets for effective ablation of persistent AF. This paper aims to discuss the clinical aspects of computational approaches that aim to identify critical sites for treatment. Various analyses of electrogram characteristics have been performed with this aim. Leading techniques for electrogram analysis are Complex Fractionated Atrial Electrograms (CFAE) and Dominant Frequency (DF). These techniques have been the subject of clinical trials of which the results are discussed. Evaluation of the activation patterns of atria in AF has been another avenue of research. Focal Impulse and Rotor Modulation (FIRM) mapping and forms of Body Surface Mapping aim to characterize multiple atrial wavelets, macro-reentry and focal sources which have been proposed as basic mechanisms perpetuating AF. Both invasive and non-invasive activation mapping techniques are reviewed. The presence of atrial fibrosis causes non-uniform anisotropic impulse propagation. Therefore, identification of fibrosis by imaging techniques is an avenue of potential research. The leading contender for imaging-based techniques is Cardiac Magnetic Resonance (CMR). As this technology advances, improvements in resolution and scar identification have positioned CMR as the mode of choice for analysis of atrial structure. AF has been demonstrated to be associated with obesity, inactivity and diseases of modern life. An opportunity exists for detailed computational analysis of the impact of risk factor modification on atrial substrate. This ranges from microstructural investigation through to examination at a population level via registries and public health interventions. Computational analysis of atrial substrate has moved from basic science toward clinical application. Future directions and potential limitations of such analyses are examined in this review. PMID- 30279662 TI - Characterization of Vitellogenin and Vitellogenin Receptor of Conopomorpha sinensis Bradley and Their Responses to Sublethal Concentrations of Insecticide. AB - Conopomorpha sinensis Bradley is the dominant borer pest of Litchi chinesis and Euphoria longan. Current management of C. sinensis relies upon insecticide application to adult moths. In addition to the direct mortality induced by insecticides, a sublethal dose of insecticides also affects growth, survival, and reproduction in the exposed insects. Vitellogenin (Vg) and vitellogenin receptor (VgR) are normally identified as essential reproduction-related proteins in insects. In this study, we characterized these two genes from C. sinensis, and investigated their differential responses to sublethal concentrations of insecticide. Cloned CsVg and CsVgR consist of 5391 and 5424-bp open reading frames, which encode proteins of 1796 and 1807 amino acid residues, respectively. The CsVg protein contains the typical vitellogenin, DUF1943 and VWFD domains as other reported lepidopteran Vgs. The CsVgR was characterized as a typical low density lipoprotein receptor with two highly conserved LBD and EGF precursor domains, one hydrophobic transmembrane domain, one cytoplasmic domain, and 13 putative N-glycosylation sites. We next assessed the sublethal effect of four major insecticides on egg-laying in C. sinensis. The toxicity against C. sinensis varied among the insecticides tested, with LC50 values ranging from 0.23 ppm for chlorpyrifos to 20.00 ppm for beta-cypermethrin, among which emamectin benzoate (EB) showed a significant negative impact on egg-laying, survival rate, ovarian development, and mating rate of C. sinensis at LC30 doses. Further investigation showed that the transcriptional level of CsVg and CsVgR were impaired in different way at 24, 48, and 72 h after EB exposure, and this result was in agreement with the diminished egg-laying of C. sinensis in the sublethal concentration EB-treated group. A repressed transcription level of CsVgR was observed at 48 h after treatment, suggesting that EB elicits a delayed response in the abundance of CsVgR. These results established different roles of CsVg and CsVgR in response to the sublethal effect of insecticides. CsVg might be a better parameter than CsVgR for assessing the effect of sublethal insecticides on reproduction in C. sinensis. PMID- 30279664 TI - Development of a Measure of Postpartum PTSD: The City Birth Trauma Scale. AB - Post-traumatic stress disorder (PTSD) affects 4% of women after birth yet there are very few questionnaire measures of postpartum PTSD that have been validated in this population. In addition, none of the available questionnaires assess postpartum PTSD in accordance with criteria specified in the latest edition of the Diagnostic and Statistical Manual [DSM-5, (1)]. The City Birth Trauma Scale is a 29-item questionnaire developed to measure birth-related PTSD according to DSM-5 criteria of: stressor criteria (A), symptoms of re-experiencing (B), avoidance (C), negative cognitions and mood (D), and hyperarousal (E), as well as duration of symptoms (F), significant distress or impairment (E), and exclusion criteria or other causes (H). Two additional items from DSM-IV were also included on the basis of evidence suggesting they might be important in this population. The first was criterion A2 that women responded to events during birth with intense fear, helplessness or horror. The second was symptoms of emotional numbing. Items were first reviewed by researchers (n = 9) and postpartum women (n = 8) and revised accordingly. The questionnaire was then completed by 950 women recruited online. Results showed the City Birth Trauma Scale had excellent reliability (Cronbach's alpha = 0.92) and is easy to understand (Flesch reading score 64.17). Exploratory factor analysis found two factors which together accounted for 56% of the variance: (i) Birth-related symptoms (40.8% variance) and (ii) General symptoms (15.5% variance). PTSD symptoms were highly associated with distress, impaired functioning, and women reporting they wanted treatment (r = 0.50-0.61). Removing DSM-IV A2 criteria only increased births classified as traumatic by 2%. Adding the item on emotional numbing did not change the psychometric properties of the scale. These items were therefore removed. The City Birth Trauma Scale has good psychometric properties and the two symptom clusters identified are consistent with previous research on symptoms of postpartum PTSD. This scale therefore provides a promising measure of PTSD following childbirth that can be used in research and clinical practice. Future research should examine the scale's predictive validity using clinical interviews. PMID- 30279663 TI - Effects of Polarized Training on Cardiometabolic Risk Factors in Young Overweight and Obese Women: A Randomized-Controlled Trial. AB - Introduction: Volume and intensity are major variables governing exercise training-mediated beneficial effects in both athletes and patients. Although polarized endurance training optimizes and maximizes physiological gains in highly trained individuals, its cardiometabolic protective-effects have not been established. The purpose of the present single site, randomized-controlled trial was to compare the effects of 12-weeks of high-intensity interval training (HIIT), moderate-intensity continuous training (MICT), and polarized volume training (POL) programs on cardiometabolic risk factors in young overweight and obese women. Materials and Methods: A total of 64 overweight/obese young women (age 23.3 +/- 3.8 years, body mass index 33.8 +/- 3.8 kg/m2) were randomly assigned to four groups: control group (CTRL), polarized volume training group, moderate-intensity endurance training group, and HIIT group. The cardiorespiratory capacity, glycemic and lipid profiles, whole-body substrate utilization, and body composition were assessed before and after the intervention. Results: After the intervention, VO2peak and power output at VO2peak increased in all exercised-groups (time effect: p < 0.0001). Power output at VT1 was increased only in the POL group compared to the CTRL group (p = 0.019). Relative fold changes in fasting plasma glucose concentrations decreased only in POL group (p = 0.002). Training induced a significant increase in relative fat oxidation in all the groups (time effect: p < 0.001). Relative fat oxidation increased only in the POL group compared to the CTRL group (training effect: p = 0.032). Conclusion: Twelve-weeks of polarized volume training showed overall superior effects on cardiorespiratory fitness, basal glycemic control, and substrate oxidation in comparison to MICT and HIIT training modalities. These data suggest that polarized volume training is an effective non-pharmacological treatment strategy for reducing cardiovascular disease risk factors in young overweight and obese women. The trial is registered at ISRCTN, number ISRCTN34421723. PMID- 30279665 TI - Five Interpersonal Factors Are Predictive of the Response to Treatment of Major Depression With Antidepressants in Primary Care. AB - Introduction: Factors relating to the interpersonal relationship between the patient and their physician and social environment are important components, which contribute to their response to treatment for major depressive disorder. This study aimed to assess the influence of optimism, perfectionism, therapeutic alliance, empathy, social support, and adherence to medication regimen in the response to antidepressant treatments in the context of normal primary care clinical practice. Method: We conducted a prospective study in which 24 primary care physicians administered sertraline or escitalopram to 89 patients diagnosed with major depressive disorder. The response to treatment and remission of the episode was assessed at 4 and 12 weeks by Cox regression. The effect of adherence to the medication regimen was assessed by multiple regression statistical techniques. Results: Adherence to medication (HR = 0.262, 95% CI = 0.125-0.553, p < 0.001) and patient perfectionism (HR = 0.259, 95% CI = 0.017-0.624, p < 0.01) negatively predicted the initial response to treatment, whereas patient optimism (HR = 1.221, 95% CI = 1.080-1.380, p < 0.05) positively predicted it. Patient optimism (HR = 1.247, 95% CI = 1.1-1.4, p < 0.05), empathy perceived by the patient (HR = 1.01, 95% CI = 1001-1002, p < 0.05), and therapeutic alliance (HR = 1.02, 95% CI = 1001-1.04, p < 0.05) positively predicted episode remission, while patient perfectionism (HR = 0.219, 95% CI = 0.093-0.515, p < 0.001) and low adherence to the treatment regimen (HR = 0.293, 95% CI = 0.145-0.595, p < 0.001) negatively predicted it. Finally, social support (p < 0.01) and therapeutic alliance (p < 0.05) predicted adherence to the medication regimen. Conclusions: In addition to taking the antidepressant drug, other factors including the personal interactions between the patient with their primary care physician and with their social environment significantly influenced the patients' initial response and the final rate of episode remission. PMID- 30279666 TI - Methylation of FKBP5 and SLC6A4 in Relation to Treatment Response to Mindfulness Based Stress Reduction for Posttraumatic Stress Disorder. AB - Mindfulness Based Stress Reduction (MBSR) is an effective non-pharmacologic treatment for veterans with PTSD. Extensive work has identified epigenetic factors related to PTSD disease risk and pathophysiology, but how these factors influence treatment response is unclear. Serotonin signaling and hypothalamic pituitary-adrenal (HPA) axis functioning may be perturbed in PTSD and are molecular pathways targeted by PTSD treatments. To identify potential biomarkers for treatment response, we utilized genomic DNA isolated from peripheral blood samples from veterans with PTSD who were responders (n = 11) or non-responders (n = 11) to MBSR as part of a clinical trial. We assessed methylation levels at CpG sites in regions of the serotonin transporter (SLC6A4) previously associated with expression and depression outcomes, as well as the Intron 7 region of the FK506 binding protein 5 (FKBP5) containing known glucocorticoid response elements suggested to regulate this gene. Selected subjects were matched across MBSR responder status by baseline symptoms, age, sex, current smoking status, and current antidepressant use. Percent methylation was compared between responders and non-responders at baseline (pre-MBSR treatment). Additionally, percent change in methylation from baseline to post-treatment was compared between responders and non-responders. There was a significant time x responder group interaction for methylation in FKBP5 intron 7 bin 2 [F (1, 19) = 7.492, p = 0.013] whereby responders had a decrease in methylation and non-responders had an increase in methylation from before to after treatment in this region. Analyses of the three CpG sites within bin 2 revealed a significant time x responder group interaction for CpG_35558513 [F (1, 19) = 5.551, p = 0.029] which resides in a known glucocorticoid response element (GRE). Decreases in FKBP5 methylation after treatment in responders as compared to increases in non-responders suggest that effective meditation intervention may be associated with stress-related pathways at the molecular level. These preliminary findings suggest that DNA methylation signatures within FKBP5 are potential indicators of response to meditation treatment in PTSD and require validation in larger cohorts. PMID- 30279667 TI - Psychosocial Risk Factors, Burnout and Hardy Personality as Variables Associated With Mental Health in Police Officers. AB - Among the variables associated with occupational stress, two of the most studied are the adverse perceptions of psychosocial risk factors in the workplace and burnout. With the rise of positive psychology, other variables of the individual type, such as hardy personality have also been the subject of study. No studies have been found that jointly examine these variables related to mental health in police officers. The aim of this research was to analyze which variables were associated with mental health in police officers. A total of 223 policemen (202 men and 21 women) participated in a cross-sectional study. Of all the variables, emotional exhaustion and perception of problems as challenges were the only factors introduced in the regression model. These factors must be considered to improve both human resource interventions and occupational health practices in this professional group. PMID- 30279668 TI - The Use of Local and Global Ordering Strategies in Number Line Estimation in Early Childhood. AB - A lot of research has been devoted to number line estimation in primary school. However, less is known about the early onset of number line estimation before children enter formal education. We propose that ordering strategies are building blocks of number line estimation in early childhood. In a longitudinal study, children completed a non-symbolic number line estimation task at age 3.5 and 5 years. Two ordering strategies were identified based on the children's estimation patterns: local and global ordering. Local ordering refers to the correct ordering of successive quantities, whereas global ordering refers to the correct ordering of all quantities across the number line. Results indicated a developmental trend for both strategies. The percentage of children applying local and global ordering strategies increased steeply from 3.5 to 5 years of age. Moreover, children used more advanced local and global ordering strategies at 5 years of age. Importantly, level of strategy use was related to more traditional number line estimation outcome measures, such as estimation accuracy and regression fit scores. These results provide evidence that children use dynamic ordering strategies when solving the number line estimation task in early stages of numerical development. PMID- 30279669 TI - Cultural Differences in Answerability Judgments. AB - Judgments about whether anyone can provide a relevant and correct answer to a question are called answerability judgments. Such judgements can be important in societal planning and decision making and may vary in different cultural contexts. Six hundred participants in each of China, India, and Sweden made answerability judgments of six difficult knowledge questions. For each question, they choose between three options indicating that they thought the question was answerable and a fourth option: "Nobody can answer that question." After each question, they rated their confidence that their judgment was correct. Choosing "Nobody can answer that question" was significantly more common for the Swedes and was uncommon in the Asian samples. The Asian samples showed higher confidence in their judgments. We suggest that these differences may be explained by results from cross-cultural research, but this study did not investigate specific mechanisms. Hence, more research is needed. PMID- 30279670 TI - Imagined Intergroup Physical Contact Improves Attitudes Toward Immigrants. AB - In this set of research, we investigated the effects of intergroup physical contact on intergroup attitudes by relying on indirect contact strategies, namely the imagined contact paradigm. We implemented the imagined contact paradigm by leading participants to shape the mental imagery upon pictorial information. Specifically, in Study 1 participants saw a picture of a white hand touching a black hand [i.e., intergroup physical contact condition (InterPC)] or a picture of an outdoor scene (i.e., control condition), and were asked to imagine being either the toucher or in the outdoor scene, respectively. Results demonstrated that InterPC compared to control condition reduced intergroup bias. In Study 2 we compared the InterPC condition to a condition in which participants saw a white hand touching another white hand [i.e., intragroup physical contact (IntraPC)], and imagined to be the toucher. Again, we found that participants in the InterPC condition showed reduced intergroup bias compared to the IntraPC. Study 3 replicated results of Studies 1 and 2 by using an implicit measure of prejudice. Also, Study 3 further showed that asking participants to merely look at the picture of a white hand touching a black hand, without imagining being the toucher was not effective in reducing implicit prejudice. Results were discussed with respect to the literature on physical contact and prejudice reduction processes. PMID- 30279671 TI - Construct Validity and Psychometric Properties of the Hebrew Version of the City Birth Trauma Scale. AB - As many as third of the women perceive their childbirth as traumatic and although prevalence rates vary between studies, around 2-5% of women in community samples may develop childbirth-related postpartum post-traumatic stress disorder (PPTSD). The City Birth Trauma Scale (BiTS) was developed to address the need for a DSM-5 based instrument that assesses PPTSD. The BiTS is a self-report questionnaire, which covers all DSM-5 PTSD criteria, including the four symptom clusters - re experiencing, avoidance, negative mood and cognitions and hyperarousal symptoms. The present study aimed to describe the psychometric properties and validate the Hebrew version of the BiTS. Five hundred and four mothers of 0- to 12-month-old infants were sampled using social media and the snowball method. Respondents completed an online survey consisting of a demographic questionnaire and the Hebrew versions of the BiTS, the impact of event scale-revised (IES-R), the Edinburgh postpartum depression scale (EPDS), and the Pittsburgh Sleep Quality Index (PSQI). The Hebrew BiTS demonstrated high internal consistency for the total scale (Cronbach alpha = 0.90) and good internal consistency (Cronbach's alpha = 0.75-0.85) for the subscales. An exploratory factor (EFA) analysis yielded a two-factors solution, accounting for 45% of variance, with general symptoms loaded on Factor 1, and childbirth-related symptoms loaded on Factor 2, with both factors demonstrating high internal consistency (Cronbach's alpha = 0.90, 0.85, respectively). High convergent validity for the symptom cluster subscales was demonstrated with the parallel IES-R subscales, EPDS and PSQI. A two-step cluster analysis indicated that dysphoric and hyperarousal symptoms best differentiated the severity of symptoms of respondents across measures. In sum, the Hebrew BiTS was psychometrically sound, indicating its utility for clinical and non-clinical research. The EFA and cluster analyses support the differentiation between symptoms of dysphoria and hyperarousal from trauma (i.e., childbirth) specific symptoms, suggesting that symptoms relating to specific aspects of the trauma differ qualitatively from general symptom in the phenomenology of PPTSD. Further research using clinical samples and comparing the BiTS to DSM-5 diagnosis using clinical interview is needed. PMID- 30279672 TI - The Role of Approximate Number System in Different Mathematics Skills Across Grades. AB - Although approximate number system (ANS) has been found to predict mathematics ability, it remains unclear if both aspects of ANS (symbolic and non-symbolic estimation) contribute equally well to mathematics performance and if their contribution varies as a function of the mathematics outcome and grade level. Thus, in this study, we examined the effects of both aspects of ANS on different mathematics skills across three grade levels. Three hundred eleven children (100 children from kindergarten, 107 children from Grade 2, and 104 children from Grade 4) from two kindergartens and three elementary schools in Shanghai, China, were assessed on measures of ANS (dot estimation and number line estimation), general cognitive ability (nonverbal intelligence, inhibition, and working memory), and mathematics abilities (numerical operations and mathematical problem solving in all grades, early mathematical skills in kindergarten, and calculation fluency in Grades 2 and 4). Results of hierarchical regression analyses showed that, in kindergarten, non-symbolic estimation predicted all mathematics skills even after controlling for age, gender, and general cognitive ability. In Grades 2 and 4, symbolic estimation accounted for unique variance in mathematical problem solving, but not in calculation fluency. Symbolic estimation also predicted numerical operations in Grade 4. Taken together, these findings suggest that in the early phases of mathematics development different aspects of ANS contribute to different mathematics skills. PMID- 30279673 TI - How Eye Movements Stabilize Posture in Patients With Bilateral Vestibular Hypofunction. AB - Chronic patients with bilateral vestibular hypofunction (BVH) complain of oscillopsia and great instability particularly when vision is excluded and on irregular surfaces. The real nature of the visual input substituting to the missing vestibular afferents and improving posture control remains however under debate. Is retinal slip involved? Do eye movements play a substantial role? The present study tends to answer this question in BVH patients by investigating their posture stability during quiet standing in four different visual conditions: total darkness, fixation of a stable space-fixed target, and pursuit of a visual target under goggles delivering visual input rate at flicker frequency inducing either slow eye movements (4.5 Hz) or saccades (1.2 Hz). Twenty one chronic BVH patients attested by both the caloric and head impulse test were examined by means of static posturography, and compared to a control group made of 21 sex-and age-matched healthy participants. The posturography data were analyzed using non-linear computation of the center of foot pressure (CoP) by means of the wavelet transform (Power Spectral Density in the visual frequency part, Postural Instability Index) and the fractional Brownian-motion analysis (stabilogram-diffusion analysis, Hausdorff fractal dimension). Results showed that posture stability was significantly deteriorated in darkness in the BVH patients compared to the healthy controls. Strong improvement of BVH patients' posture stability was observed during fixation of a visual target, pursuit with slow eye movements, and saccades, whereas the postural performance of the control group was less affected by the different visual conditions. It is concluded that BVH patients improve their posture stability by (1) using extraocular signals from eye movements (efference copy, muscle re-afferences) much more than the healthy participants, and (2) shifting more systematically than the controls to a more automatic mode of posture control when they are in dual-task conditions associating the postural task and a concomitant visuo- motor task. PMID- 30279674 TI - Degraded Synergistic Recruitment of sEMG Oscillations for Cerebral Palsy Infants Crawling. AB - Background: Synergistic recruitment of muscular activities is a generally accepted mechanism for motor function control, and motor dysfunction, such as cerebral palsy (CP), destroyed the synergistic electromyography activities of muscle group for limb movement. However, very little is known how motor dysfunction of CP affects the organization of the myoelectric frequency components due to the abnormal motor unit recruiting patterns. Objectives: Exploring whether the myoelectric activity can be represented with synergistic recruitment of surface electromyography (sEMG) frequency components; evaluating the effect of CP motor dysfunction on the synergistic recruitment of sEMG oscillations. Methods: Twelve CP infants and 17 typically developed (TD) infants are recruited for self-paced crawling on hands and knees. sEMG signals have been recorded from bilateral biceps brachii (BB) and triceps brachii (TB) muscles. Multi-scale oscillations are extracted via multivariate empirical mode decomposition (MEMD), and non-negative matrix factorization (NMF) method is employed to obtain synergistic pattern of these sEMG oscillations. The coefficient curve of sEMG oscillation synergies are adopted to quantify the time varying recruitment of BB and TB myoelectric activity during infants crawling. Results: Three patterns of sEMG oscillation synergies with specific frequency ranges are extracted in BB and TB of CP or TD infants. The contribution of low frequency oscillation synergy of BB in CP group is significantly less than that in TD group (p < 0.05) during forward swing phase for slow contraction; however, this low-frequency oscillation synergy keep higher level during the backward swing phase crawling. For the myoelectric activities of TB, there is not enough high-frequency oscillation recruitment of sEMG for the fast contraction in propulsive phase of CP infants crawling. Conclusion: Our results reveal that, the myoelectric activities of a muscle can be manifested as sEMG oscillation synergies, and motor dysfunction of CP degrade the synergistic recruitment of sEMG oscillations due to the impaired CNS regulation and destroyed MU/muscle fiber. Our preliminary work suggests that time-varying coefficient curve of sEMG oscillation synergies is a potential index to evaluate the abnormal recruitment of electromyography activities affected by CP disorders. PMID- 30279676 TI - Concussions in Sledding Sports and the Unrecognized "Sled Head": A Systematic Review. AB - Background: Sport-related concussion is a significant public health concern. Little research has been conducted on sport-related concussion and injury prevention strategies in competitive sledding sports like bobsleigh, luge, and skeleton. Athletes have identified "sled head" as a key concern due to its symptom burden. Purpose: To summarize our knowledge of the prevalence of concussion and related symptoms in sledding sports; to utilize Haddon's Matrix to inform and define strategies for injury prevention. Methods: An independent information specialist conducted a search for the known literature on injuries in non-recreational sledding sports, and specifically for concussion via OVID Medline, CINAHL, the Cochrane Database, EMBASE, PsycInfo, PubMed, Scopus, and the Web of Sciences from 1946 to December 2017. After iterative searches of reference sections, a total of 844 articles were assessed for inclusion. Results: Nine articles were included for review. Concussions are a common occurrence in elite sledding sport athletes, affecting 13-18% of all sledding athletes. Significant variance exists between events, indicating a potential effect of the ice track in injury risk. The condition known as "sled head" is discussed and identified as a key point of further investigation. A number of potential injury prevention strategies are discussed. Interpretation: Head injuries and concussions are an important injury for elite sledding sports and a number of avenues exist for prevention. More work is required to delineate the mechanisms, characteristics, natural history and management of "sled head." PMID- 30279675 TI - Structural, Microstructural, and Metabolic Alterations in Primary Progressive Aphasia Variants. AB - Neuroimaging studies have described the brain alterations in primary progressive aphasia (PPA) variants (semantic, logopenic, nonfluent/agrammatic). However, few studies combined T1, FDG-PET, and diffusion MRI techniques to study atrophy, hypometabolism, and tract alterations across the three PPA main variants. We therefore explored a large early-stage cohort of semantic, logopenic and nonfluent/agrammatic variants (N = 86) and of 23 matched healthy controls with anatomical MRI (cortical thickness), FDG PET (metabolism) and diffusion MRI (white matter tracts analyses), aiming at identifying cortical and sub-cortical brain alterations, and confronting these alterations across imaging modalities and aphasia variants. In the semantic variant, there was cortical thinning and hypometabolism in anterior temporal cortices, with left-hemisphere predominance, extending toward posterior temporal regions, and affecting tracts projecting to the anterior temporal lobes (inferior longitudinal fasciculus, uncinate fasciculus) and tracts projecting to or running nearby posterior temporal cortices: (superior longitudinal fasciculus, inferior frontal-occipital fasciculus). In the logopenic variant metabolic alterations were more extensive than atrophy affecting mainly the left temporal-parietal junction and extending toward more anterior temporal cortices. Metabolic and tract data were coherent given the alterations of the left superior and inferior longitudinal fasciculus and the left inferior frontal-occipital fasciculus. In the nonfluent/agrammatic variant cortical thinning and hypometabolism were located in the left frontal cortex but Broca's area was only affected on metabolic measures. Metabolic and tract alterations were coherent as reflected by damage to the left uncinate fasciculus connecting with Broca's area. Our findings provide a full-blown statistically robust picture of brain alterations in early-stage variants of primary progressive aphasia which has implications for diagnosis, classification and future therapeutic strategies. They demonstrate that in logopenic and semantic variants patterns of brain damage display a non-negligible overlap in temporal regions whereas they are substantially distinct in the nonfluent/agrammatic variant (frontal regions). These results also indicate that frontal networks (combinatorial syntax/phonology) and temporal networks (lexical/semantic representations) constitute distinct anatomo-functional entities with differential vulnerability to degenerative processes in aphasia variants. Finally, the identification of the specific damage patterns could open an avenue for trans-cranial stimulation approaches by indicating the appropriate target-entry into the damaged language system. PMID- 30279678 TI - Socioeconomic Position and Picky Eating Behavior Predict Disparate Weight Trajectories in Infancy. AB - Infant weight gain has long-term implications for the establishment of overall health. We examined whether socioeconomic position (SEP), the use of pressure as a feeding practice, and picky eating relate to changes infant in weight-for length (WFL). A modified developmental design was used to examine whether current levels of child picky eating, parental use of pressure, and SEP were associated with changes in WFL during infancy. Health providers distributed survey packets during routine well-child visits made in the homes of families with young children in New Zealand (n = 193). Primary caregivers of young children provided their child's current level of picky eating, their use of pressure, and their SEP. They also reported their child's professionally-measured WFL from birth, 8, 15, and 21 months of age. A multi-level modeling analysis yielded an interaction between SEP and picky eating in predicting infant weight change over time. Children who had a low SEP and were not picky eaters were on the highest WFL trajectory and children who had a low SEP and were picky eaters were lowest on the WFL trajectory. A main effect revealed that higher levels of parental pressure predicted lower WFL in infants at each age, but did not interact with SEP or picky eating. Findings from this study indicate that the combination of eating behavior and SEP are associated with differential infant growth patterns. These results suggest that eating behavior and SEP should be included in the development of interventions designed to achieve healthy weight during childhood. PMID- 30279677 TI - Progestin and Nuclear Progestin Receptor Are Essential for Upregulation of Metalloproteinase in Zebrafish Preovulatory Follicles. AB - Ovulation requires proteinases to promote the rupture of ovarian follicles. However, the identity of these proteinases remains unclear. In our previous studies using RNA-seq analysis of differential expressed genes, we found significant down-regulation of five metalloproteinases: adam8b (a disintegrin and metalloproteinase domain 8b), adamts8a (a disintegrin and metalloproteinase with thrombospondin motif 8a), adamts9, mmp2 (matrix metalloproteinase 2), and mmp9 in the nuclear progestin receptor knockout (pgr -/-) zebrafish that have failed to ovulate. We hypothesize that these metalloproteinases are responsible for ovulation and are regulated by progestin and Pgr. In this study, we first determined the expression of these five metalloproteinases and adamts1 in preovulatory follicles at different times within the spawning cycle in pgr -/- and wildtype (wt) zebrafish and under varying hormonal treatments. We found that transcripts of adam8b, adamts1, adamts9, and mmp9 increased drastically in the preovulatory follicular cells of wt female zebrafish, while changes of adamts8a and mmp2 were not significant. This increase of adam8b, adamts9, and mmp9 was significantly reduced in pgr -/-, whereas expression of adamts1 was not affected in pgr -/- zebrafish. Among upregulated metalloproteinases, adamts9 mRNA was found to be expressed specifically in follicular cells. Strong immunostaining of Adamts9 protein was observed in the follicular cells of wt fish, and this expression was reduced drastically in pgr -/-. Interestingly, about an hour prior to the increase of metalloproteinases in wt fish, both Pgr transcript and protein increased transiently in preovulatory follicular cells. The results from in vitro experiments showed that adamts9 expression markedly increased in a dose, time and Pgr-dependent manner when preovulatory follicles were exposed to a progestin, 17alpha,20beta-dihydroxy-4-pregnen-3-one (DHP). Taken together, our results provide the first evidence that upregulation of adamts9 occurs specifically in preovulatory follicular cells of zebrafish prior to ovulation. Progestin and its receptor (Pgr) are essential for the upregulation of metalloproteinases. PMID- 30279679 TI - The New TNM Staging System for Thyroid Cancer and the Risk of Disease Downstaging. AB - In October 2016 the American Joint Committee on Cancer (AJCC) published the 8th edition of the AJCC/TNM cancer staging system and it has been introduced in clinical practice since 1st January 2018. The effect of most of the changes in the new edition was the downstaging of a significant number of patients into lower stages, reflecting their low risk of thyroid cancer-related death. One of the most relevant modification refers to the role of the microscopic extra thyroidal tumor invasion, which is no longer considered as criterion for the classification of T3 tumors. With the present study we want to assess the impact of the changes of the new staging system and therefore we analyzed or casistic of 84 T1-T3 thyroid-cancer patients. The results of our analysis show that he downstaging of patients according to the 8th TNM edition does not necessarily reflect less aggressive disease: we actually reported 2 lymph-nodal recurrences (40%) in the five patients that were downstaged from pT3 to pT2 and the lypmh nodal recurrence rate for stage I rises from 0% with the 7th TNM edition to 5.3% with the 8th edition. PMID- 30279680 TI - Expanding the Current Knowledge About the Role of Interleukin-10 to Major Concerning Bacteria. AB - Interleukin-10 (IL-10) is one of the most important anti-inflammatory cytokine produced during bacterial infection. Two related phenomena explain the importance of IL-10 production in this context: first, the wide range of cells able to produce this cytokine and second, the wide effects that it causes on target cells. In a previous report we described opposing roles of IL-10 production during bacterial infection. Overall, during infections caused by intracellular bacteria or by pathogens that modulate the inflammatory response, IL-10 production facilitates bacterial persistence and dissemination within the host. Whereas during infections caused by extracellular or highly inflammatory bacteria, IL-10 production reduces host tissue damage and facilitates host survival. Given that these data were obtained using antibiotic susceptible bacteria, the potential application of these studies to multi-drug resistant (MDR) bacteria needs to be evaluated. MDR bacteria can become by 2050 a major death cause worldwide, not only for its ability to resist antimicrobial therapy but also because the virulence of these strains is different as compared to antibiotic susceptible strains. Therefore, it is important to understand the interaction of MDR-bacteria with the immune system during infection. This review discusses the current data about the role of IL-10 during infections caused by major circulating antibiotic resistant bacteria. We conclude that the production of IL-10 improves host survival during infections caused by extracellular or highly inflammatory bacteria, however, it is detrimental during infections caused by intracellular bacteria or bacterial pathogens that modulate the inflammatory response. Importantly, during MDR-bacterial infections a differential IL-10 production has been described, compared to non-MDR bacteria, which might be due to virulence factors specific of MDR bacteria that modulate production of IL-10. This knowledge is important for the development of new therapies against infections caused by these bacteria, where antibiotics effectiveness is dramatically decreasing. PMID- 30279682 TI - Switching and Torque Generation in Swarming E. coli. AB - Escherichia coli swarm on semi-solid surfaces with the aid of flagella. It has been hypothesized that swarmer cells overcome the increased viscous drag near surfaces by developing higher flagellar thrust and by promoting surface wetness with the aid of a flagellar switch. The switch enables reversals between clockwise (CW) and counterclockwise (CCW) directions of rotation of the flagellar motor. Here, we measured the behavior of flagellar motors in swarmer cells. Results indicated that although the torque was similar to that in planktonic cells, the tendency to rotate CCW was higher in swarmer cells. This suggested that swarmers likely have a smaller pool of phosphorylated CheY. Results further indicated that the upregulation of the flagellin gene was not critical for flagellar thrust or swarming. Consistent with earlier reports, moisture added to the swarm surface restored swarming in a CCW-only mutant, but not in a FliG mutant that rotated motors CW-only (FliGCW). Fluorescence assays revealed that FliGCW cells grown on agar surfaces carried fewer flagella than planktonic FliGCW cells. The surface-dependent reduction in flagella correlated with a reduction in the number of putative flagellar preassemblies. These results hint toward a possibility that the conformational dynamics of switch proteins play a role in the proper assembly of flagellar complexes and flagellar export, thereby aiding bacterial swarming. PMID- 30279681 TI - Microbial Communities Associated With Indigo Fermentation That Thrive in Anaerobic Alkaline Environments. AB - Indigo fermentation, which depends on the indigo-reducing action of microorganisms, has traditionally been performed to dye textiles blue in Asia as well as in Europe. This fermentation process is carried out by naturally occurring microbial communities and occurs under alkaline, anaerobic conditions. Therefore, there is uncertainty regarding the fermentation process, and many unknown microorganisms thrive in this unique fermentation environment. Until recently, there was limited information available on bacteria associated with this fermentation process. Indigo reduction normally occurs from 4 days to 2 weeks after initiation of fermentation. However, the changes in the microbiota that occur during the transition to an indigo-reducing state have not been elucidated. Here, the structural changes in the bacterial community were estimated by PCR-based methods. On the second day of fermentation, a large change in the redox potential occurred. On the fourth day, distinct substitution of the genus Halomonas with the aerotolerant genus Amphibacillus was observed, corresponding to marked changes in indigo reduction. Under open-air conditions, indigo reduction during the fermentation process continued for 6 months on average. The microbiota, including indigo-reducing bacteria, was continuously replaced with other microbial communities that consisted of other types of indigo reducing bacteria. A stable state consisting mainly of the genus Anaerobacillus was also observed in a long-term fermentation sample. The stability of the microbiota, proportion of indigo-reducing microorganisms, and appropriate diversity and microbiota within the fluid may play key factors in the maintenance of a reducing state during long-term indigo fermentation. Although more than 10 species of indigo-reducing bacteria were identified, the reduction mechanism of indigo particle is riddle. It can be predicted that the mechanism involves electrons, as byproducts of metabolism, being discarded by analogs mechanisms reported in bacterial extracellular solid Fe3+ reduction under alkaline anaerobic condition. PMID- 30279684 TI - A Major Facilitator Superfamily Transporter Regulated by the Stress-Responsive Transcription Factor Yap1 Is Required for Resistance to Fungicides, Xenobiotics, and Oxidants and Full Virulence in Alternaria alternata. AB - Alternaria alternata relies on the ability to produce a host-selective toxin and to detoxify reactive oxygen species to successfully colonize the host. An A. alternata major facilitator superfamily transporter designated AaMFS54 was functionally characterized by analysis of loss- and gain-of-function mutations to better understand the factors required for fungal pathogenesis. AaMFS54 was originally identified from a wild-type expression library after being subtracted with that of a mutant impaired for the oxidative stress-responsive transcription regulator Yap1. AaMFS54 contains 14 transmembrane helixes. Fungal mutant lacking AaMFS54 produced fewer conidia and increased sensitivity to many potent oxidants (potassium superoxide and singlet-oxygen generating compounds), xenobiotics (2,3,5-triiodobenzoic acid and 2-chloro-5-hydroxypyridine), and fungicides (clotrimazole, fludioxonil, vinclozolin, and iprodione). AaMFS54 mutant induced necrotic lesion sizes similar to those induced by wild-type on leaves of susceptible citrus cultivars after point inoculation with spore suspensions. However, the mutant produced smaller colonies and less fluffy hyphae on the affected leaves. Virulence assays on citrus leaves inoculated by spraying with spores revealed that AaMFS54 mutant induced less severe lesions than wild-type, indicating the requirement of AaMFS54 in pathogenesis. All defective phenotypes were restored in a strain re-acquiring a functional copy of AaMFS54. Northern blotting analysis revealed that the expression of AaMFS54 was suppressed by xenobiotics. The current studies indicate that the Yap1-mediated transporter plays a role in resistance to toxic oxidants and fungicides in A. alternata. The relationships of MFS transporters with other regulatory components conferring stress resistance and A. alternata pathogenesis are also discussed. PMID- 30279683 TI - Dietary Bile Salt Types Influence the Composition of Biliary Bile Acids and Gut Microbiota in Grass Carp. AB - Lipid metabolism can influence host's health. There is increasing evidence for interplay between two key regulating factors in lipid metabolism: bile acids (BAs) and gut microbiota. However, very little is known about how types of different diet-supplemented bile salts (BS) influence this interaction in vivo. We sought to explore these relationships using grass carp (Ctenopharyngodon idellus), which often suffers functional disorder of liver and gallbladder. We studied fluctuations of BAs in the gall and changes of microbial communities in the gut in response to seven different diets: five different BS, chelating BS agent, and control. The BS comprised two primary BS [sodium taurochololate (TCAS) and sodium taurochenodeoxycholate (TCDCAS)], sodium tauroursodeoxycholate (TUDCAS), and two secondary BS [sodium taurodeoxycholate (TDCAS) and sodium taurolithocholate (TLCAS)]. Supplementation of primary BS caused a more significant fluctuation of biliary BAs than secondary BS, and TCAS caused a more prominent increase than TCDCAS and TUDCAS. For the gut microbiota, primary BS tended to increase their diversity and induce community succession, secondary BS resulted in a higher firmicutes/bacteroidetes ratio, while TUDCAS had no significant effects. Changes of the gut microbiota triggered by different types of BS caused alteration in BAs biotransformation. Two-obesity-associated families, Lachnospiraceae and Ruminococcaceae were positively correlated with biliary cholic acid (CA), taurochenodeoxycholic acid (TCDCA), and deoxycholic acid (DCA). As both primary and secondary BS resulted in increased synthesis of toxic secondary Bas by the gut microbiota, future studies should pay closer attention to gut microbiota when considering BA treatment. PMID- 30279685 TI - Low-Dose Radiotherapy Ameliorates Advanced Arthritis in hTNF-alpha tg Mice by Particularly Positively Impacting on Bone Metabolism. AB - Inflammation and bone erosion are central in rheumatoid arthritis (RA). Even though effective medications for control and treatment of RA are available, remission is only seen in a subset of patients. Treatment with low-dose radiotherapy (LD-RT) which has been already successfully used for amelioration of symptoms in benign diseases should be a promising approach to reduce pain, inflammation, and particularly bone erosion in patients with RA. Even though anti inflammatory effects of LD-RT are already described with non-linear dose response relationships, and pain-reducing effects have been clinically observed, the underlying mechanisms are widely unknown. Besides immune cells many other cell types, such as fibroblast-like synoviocytes (FLS), osteoclasts, and osteoblast are present in the affected joint and might be modulated by LD-RT. For this study, these cell types were obtained from human tumor necrosis factor-alpha transgenic (hTNF-alpha tg) mice and were consecutively exposed to different doses of ionizing radiation (0.1, 0.5, 1.0, and 2.0 Gy, respectively) in vitro. In order to study the in vivo effects of LD-RT within the arthritic joint, hind paws of arthritic hTNF-alpha tg mice were locally irradiated with 0.5 Gy, a single dose per fraction that is known for good clinical responses. Starting at a dose of 0.5 Gy, proliferation of FLS was reduced and apoptosis significantly enhanced with no changes in necrosis. Further, expression of RANK-L was slightly reduced following irradiation with particularly 0.5 Gy. Starting from 0.5 Gy, the numbers of differentiated osteoclasts were significantly reduced, and a lower bone resorbing activity of treated osteoclasts was also observed, as monitored via pit formation and Cross Laps presence. LD-RT had further a positive effect on osteoblast-induced mineralization in a discontinuous dose response relationship with 0.5 Gy being most efficient. An increase of the gene expression ratio of OPG/RANK-L at 0.1 and 0.5 Gy and of production of OPG at 0.5 and 1.0 Gy was observed. In vivo, LD-RT resulted in less severe arthritis in arthritic hTNF alpha tg mice and in significant reduction of inflammatory and erosive area with reduced osteoclasts and neutrophils. Locally applied LD-RT can, therefore, induce a beneficial micro-environment within arthritic joints by predominantly positively impacting on bone metabolism. PMID- 30279687 TI - FIBCD1 Binds Aspergillus fumigatus and Regulates Lung Epithelial Response to Cell Wall Components. AB - Aspergillus fumigatus (A. fumigatus) is a ubiquitous fungus of clinical importance associated with development of various pulmonary diseases and allergic hypersensitivity reactions. It is protected against environmental stress by a cell wall that contains polysaccharides such as chitin. We previously demonstrated that fibrinogen C domain-containing protein 1 (FIBCD1) is a membrane bound protein that binds chitin through a conserved S1 binding site and is expressed in intestinal epithelium and salivary glands. Here, we further localized FIBCD1 protein expression at the surface of bronchial and alveolar human lung epithelium, observed recognition of A. fumigatus cell wall with S1 site-independent recognition. We observed FIBCD1-mediated suppression of IL-8 secretion, mucin production, and transcription of genes associated with airway inflammation and homeostasis in FIBCD1-transfected lung epithelial cells. These modulations were generally enforced by stimulation with A. fumigatus cell wall polysaccharides. In parallel, we demonstrated a FIBCD1-mediated modulation of IL 8 secretion induced by TLR2,-4, and -5. Collectively, our findings support FIBCD1 as a human lung epithelial pattern recognition receptor that recognizes the complex A. fumigatus cell wall polysaccharides and modulates the lung epithelial inflammatory response by suppressing inflammatory mediators and mucins. PMID- 30279686 TI - Anti-LL37 Antibodies Are Present in Psoriatic Arthritis (PsA) Patients: New Biomarkers in PsA. AB - Psoriatic arthritis (PsA) is a chronic inflammatory arthritis associated with psoriasis. A third of psoriatic patients develop PsA via unknown mechanisms. No reliable diagnostic markers are available for PsA, or prognostic biomarkers for PsA development in psoriasis. We previously uncovered a pro-inflammatory role for cathelicidin LL37 in lesional psoriasis skin. LL37 binds nucleic acids and stimulates plasmacytoid/myeloid dendritic cells (pDC, mDCs) to secrete type I interferon (IFN-I) and pro-inflammatory factors. LL37 becomes an autoantigen for psoriatic Th1-Th17/CD8 T cells. Anti-LL37 antibodies were detected in systemic lupus erythematosus, an autoimmune disease characterized by neutrophil extracellular-traps release (NETosis) in target organs. LL37 can be substrate of irreversible post-translational modifications, citrullination or carbamylation, linked to neutrophil activity. Here we analyzed inflammatory factors, included LL37, in PsA and psoriasis plasma and PsA synovial fluids (SF)/biopsies. We show that LL37 (as a product of infiltrating neutrophils) and autoantibodies to LL37 are elevated in PsA, but not OA SF. Anti-LL37 antibodies correlate with clinical inflammatory markers. Anti-carbamylated/citrullinated-LL37 antibodies are present in PsA SF/plasma and, at lower extent, in psoriasis plasma, but not in controls. Plasma anti-carbamylated-LL37 antibodies correlate with PsA (DAS44) but not psoriasis (PASI) disease activity. Ectopic lymphoid structures, and deposition of immunoglobulin-(Ig)G-complexes (IC) co-localizing with infiltrating neutrophils, are observed in PsA and not OA synovial tissues (ST). Activated complement (C5a, C9), GM-CSF and IFN-I are up-regulated in PsA and not OA synovia and in PsA and psoriasis plasma but not in HD. C9 and GM-CSF levels in PsA SF correlate with clinical inflammatory markers and DAS44 (C9) and with anti carbamylated/citrullinated-LL37 antibodies (GM-CSF and IFN-I). Thus, we uncover a role for LL37 as a novel PsA autoantibody target and correlation studies suggest participation of anti-LL37 antibodies to PsA pathogenesis. Notably, plasma antibodies to carbamylated-LL37, which correlate with DAS44, suggest their use as new disease activity markers. GM-CSF and complement C5a and C9 elevation may be responsible for autoantigens release by neutrophils and their modification, fueling inflammation and autoreactivity establishment. Finally, targeting GM-CSF, C5a, C9 can be beneficial in PsA. PMID- 30279689 TI - Treatment of Granulomas in Patients With Ataxia Telangiectasia. AB - Background: Ataxia telangiectasia (A-T) is a devastating multi-system disorder characterized by progressive cerebellar ataxia, growth retardation, immunodeficiency, chronic pulmonary disease and chromosomal instability. Cutaneous granulomas are a known phenomenon in A-T but extra-dermal manifestation of granulomas at bone and synovia has not been reported so far. The clinical presentation, immunological findings, the long-term course and treatment options of eight patients with severe granulomas will be reported. Methods: From our cohort of 44 classical A-T patients, eight patients aged 2-11 years (18.2%) presented with granulomas. Immunological features of patients with and without granulomas were compared. Five patients suffered from cutaneous manifestation, in two patients we detected a bone and in one a joint involvement. Patients with significant extra-dermal involvement as well as one patient with massive skin manifestation were treated with TNF inhibitors. The patient with granulomas at his finger joint and elbow was treated with hematopoietic stem cell transplantation (HSCT). Results: Interestingly, seven of eight patients with granulomas were total IgA deficient, but there were no differences in IgG and IgM levels. All lymphocytes subsets were equally distributed except patients with granuloma had significantly lower naive CD8 cells. In patients without treatment, four of eight showed a slow but significant enlargement of the granuloma. Treatment success with TNF inhibitors was variable. In one patient, treatment with TNF inhibitors led to a total remission for 3 years up to now. In two patients, treatment with TNF inhibitors led to a partial regression of granulomas. Treatment interruptions caused deterioration again. Conclusions: Granulomas in A-T progress slowly over years and can lead to significant morbidity.Treatment with TNF inhibitors was safe and in part successful in our patients. Interestingly HSCT leads to complete remission, and indicates that aberrant immune function is responsible for granulomas in A-T patients. What This Study Adds to the Field: Granulomas in A-T progress slowly over years and can lead to significant morbidity. Treatment with TNF inhibitors was safe and in part successful in our patients. AT A GLANCE COMMENTARY: Scientific knowledge on the subject: Little is known about the clinical presentation, course and treatment of granulomas in ataxia telangiectasia (A-T). In addition, this is the first report of extra-dermal manifestation of granulomas at bone and synovia in patients with A-T. What This Study Adds to the Field: Granulomas in A-T progress slowly over years and can lead to significant morbidity. Treatment with TNF inhibitors was safe and in part successful in our patients. PMID- 30279688 TI - Taurodeoxycholate Increases the Number of Myeloid-Derived Suppressor Cells That Ameliorate Sepsis in Mice. AB - Bile acids (BAs) control metabolism and inflammation by interacting with several receptors. Here, we report that intravenous infusion of taurodeoxycholate (TDCA) decreases serum pro-inflammatory cytokines, normalizes hypotension, protects against renal injury, and prolongs mouse survival during sepsis. TDCA increases the number of granulocytic myeloid-derived suppressor cells (MDSCLT) distinctive from MDSCs obtained without TDCA treatment (MDSCL) in the spleen of septic mice. FACS-sorted MDSCLT cells suppress T-cell proliferation and confer protection against sepsis when adoptively transferred better than MDSCL. Proteogenomic analysis indicated that TDCA controls chromatin silencing, alternative splicing, and translation of the immune proteome of MDSCLT, which increases the expression of anti-inflammatory molecules such as oncostatin, lactoferrin and CD244. TDCA also decreases the expression of pro-inflammatory molecules such as neutrophil elastase. These findings suggest that TDCA globally edits the proteome to increase the number of MDSCLT cells and affect their immune-regulatory functions to resolve systemic inflammation during sepsis. PMID- 30279690 TI - Physiological Stimuli Induce PAD4-Dependent, ROS-Independent NETosis, With Early and Late Events Controlled by Discrete Signaling Pathways. AB - Neutrophils are known to extrude decondensed chromatin, thus forming NETs (neutrophil extracellular traps). These structures immobilize pathogens, thereby preventing their spreading, and are also adorned with antimicrobial molecules. NETs can also influence pathogenesis in chronic inflammation, autoimmunity, and cancer. Despite the importance of NETs, the molecular mechanisms underlying their formation, as well as the upstream signaling pathways involved, are only partially understood. Likewise, current methodological approaches to quantify NETs suffer from significant drawbacks, not the least being the inclusion of a significant non-specific signal. In this study, we used novel, fluorescent polymers that only bind extruded chromatin, allowing a specific and standardized quantification of NETosis. This allowed us to reliably rank the relative potency of various physiologic NET inducers. In neutrophils activated with such stimuli, inhibition of the Syk or PI3K pathways blocked NETosis by acting upon late events in NET formation. Inhibition of the TAK1, p38 MAPK, or MEK pathways also hindered NETosis, but by acting on early events. By contrast, inhibiting PKC, Src family kinases, or JNK failed to prevent NETosis; cycloheximide or actinomycin D were also ineffective. Expectedly, NET formation was deeply compromised following inhibition of the NADPH oxidase in PMA-activated neutrophils, but was found to be ROS-independent in response to physiological agonists. Conversely, we show for the first time in human neutrophils that selective inhibition of PAD4 potently prevents NETosis by all stimuli tested. Our data substantially extends current knowledge of the signaling pathways controlling NETosis, and reveals how they affect early or late stages of the phenomenon. In view of the involvement of NETs in several pathologies, our findings also identify molecular targets that could be exploited for therapeutic intervention. PMID- 30279692 TI - T Cells on Engineered Substrates: The Impact of TCR Clustering Is Enhanced by LFA 1 Engagement. AB - We created APC-mimetic synthetic substrates to study the impact of ligand clustering on T cell activation and spreading. The substrates exhibit antibodies directed against the TCR-complex in the form of a patterned array of sub micrometric dots surrounded by a fluid supported lipid bilayer (SLB) which may itself be functionalized with another bio-molecule. We show that for T cell adhesion mediated by T cell receptor (TCR) alone, in the patterned, but not in the corresponding homogeneous controls, the TCR, ZAP-70 and actin are present in the form of clusters or patches that co-localize with the ligand-dots. However, global cell scale parameters like cell area and actin distribution are only weakly impacted by ligand clustering. In presence of ICAM-1 - the ligand of the T cell integrin LFA-1 - on the SLB, the TCR is still clustered due to the patterning of its ligands, but now global parameters are also impacted. The actin organization changes to a peripheral ring, resembling the classical actin distribution seen on homogeneous substrates, the patterned membrane topography disappears and the membrane is flat, whereas the cell area increases significantly. These observations taken together point to a possible pivotal role for LFA-1 in amplifying the effect of TCR-clustering. No such effect is evident for co-engagement of CD28, affected via its ligand B7.2. Unlike on ICAM-1, on B7.2 cell spreading and actin organization are similar for homogeneous and patterned substrates. However, TCR and ZAP-70 clusters are still formed in the patterned case. These results indicate complementary role for LFA-1 and CD28 in the regulation and putative coupling of TCR micro-clusters to actin. The engineered substrates presented here clearly have the potential to act as platform for fundamental research in immune cell biology, as well as translational analyses in immunotherapy, for example to screen molecules for their role in T cell adhesion/activation. PMID- 30279693 TI - Unraveling Rice Tolerance Mechanisms Against Schizotetranychus oryzae Mite Infestation. AB - Rice is the staple food for over half of the world's population. Infestation of Schizotetranychus oryzae (Acari: Tetranychidae) causes great losses in rice productivity. To search for rice genotypes that could better tolerate S. oryzae infestation, we evaluated morphological and production parameters in Brazilian cultivars, and identified two cultivars with contrasting responses. Leaf damage during infestation was similar for all cultivars. However, infestation in Puita INTA-CL resulted in reduction in the number of seeds per plant, percentage of full seeds, weight of 1,000 seeds, and seed length, whereas infestation in IRGA 423 increased weight of 1,000 seeds and seed length. Reduction in seed weight per plant caused by infestation was clearly higher in Puita INTA-CL (62%) compared to IRGA 423 (no reduction detected), thus Puita INTA-CL was established as susceptible, and IRGA 423 as tolerant to S. oryzae infestation. Photosynthetic parameters were less affected by infestation in IRGA 423 than in Puita INTA-CL, evidencing higher efficiency of energy absorption and use. S. oryzae infestation also caused accumulation of H2O2, decreased cell membrane integrity (indicative of cell death), and accelerated senescence in leaves of Puita INTA-CL, while leaves of IRGA 423 presented higher levels of total phenolics compounds. We performed proteomics analysis of Puita INTA-CL and IRGA 423 leaves after 7 days of infestation, and identified 60 differentially abundant proteins (28 more abundant in leaves of Puita INTA-CL and 32 in IRGA 423). Proteins related to plant defense, such as jasmonate synthesis, and related to other mechanisms of tolerance such as oxidative stress, photosynthesis, and DNA structure maintenance, together with energy production and general metabolic processes, were more abundant in IRGA 423. We also detected higher levels of silicon (as amorphous silica cells) in leaves of infested IRGA 423 plants compared to Puita INTA-CL, an element previously linked to plant defense, indicating that it could be involved in tolerance mechanisms. Taken together, our data show that IRGA 423 presents tolerance to S. oryzae infestation, and that multiple mechanisms might be employed by this cultivar. These findings could be used in biotechnological approaches aiming to increase rice tolerance to mite infestation. PMID- 30279691 TI - Mathematical Analysis of Cytokine-Induced Differentiation of Granulocyte-Monocyte Progenitor Cells. AB - Granulocyte-monocyte progenitor (GMP) cells play a vital role in the immune system by maturing into a variety of white blood cells, including neutrophils and macrophages, depending on exposure to cytokines such as various types of colony stimulating factors (CSF). Granulocyte-CSF (G-CSF) induces granulopoiesis and macrophage-CSF (M-CSF) induces monopoiesis, while granulocyte/macrophage-CSF (GM CSF) favors monocytic and granulocytic differentiation at low and high concentrations, respectively. Although these differentiation pathways are well documented, the mechanisms behind the diverse behavioral responses of GMP cells to CSFs are not well understood. In this paper, we propose a mechanism of interacting CSF-receptors and transcription factors that control GMP differentiation, convert the mechanism into a set of differential equations, and explore the properties of this mathematical model using dynamical systems theory. Our model reproduces numerous experimental observations of GMP cell differentiation in response to varying dosages of G-CSF, M-CSF, and GM-CSF. In particular, we are able to reproduce the concentration-dependent behavior of GM CSF induced differentiation, and propose a mechanism driving this behavior. In addition, we explore the differentiation of a fourth phenotype, monocytic myeloid derived suppressor cells (M-MDSC), showing how they might fit into the classical pathways of GMP differentiation and how progenitor cells can be primed for M-MDSC differentiation. Finally, we use the model to make novel predictions that can be explored by future experimental studies. PMID- 30279695 TI - Malaysian Carica papaya L. var. Eksotika: Current Research Strategies Fronting Challenges. AB - Carica papaya L. or commonly known as papaya, is a major tropical crop consumed worldwide either as a vegetable or fresh fruit or processed products. In Malaysia, papaya was initially planted as a smallholder crop throughout the country. Eventually after 15 years of breeding and selection, a new variety, named C. papaya L. var. Eksotika, was released by the Malaysian Agricultural Research and Development Institute (MARDI) in 1987. This event changed the outlook of papaya planting from a smallholder crop to a plantation crop. Despite the blooming papaya business, the industry faced various disease issues that jeopardize its future. The most devastating was the papaya dieback disease, which affected approximately 800 hectares of plantation, destroyed approximately 1 million trees nationwide with total losses estimated at US$ 58 million. Even though Eksotika is a favored commercial variety with good eating and aesthetic quality fruit, its potential for more lucrative distant markets is tarnished with its short-shelf life fruits. Several strategies had been reported to address the challenges faced by Eksotika specifically against the dieback disease and the fruit's short shelf-life. This review focuses on C. papaya L. var. Eksotika particularly on the strategies to address the challenges faced in order to sustain the economic value of this crop plant, which had contributed significantly to the Malaysian economy. PMID- 30279694 TI - Light, Ethylene and Auxin Signaling Interaction Regulates Carotenoid Biosynthesis During Tomato Fruit Ripening. AB - Light signaling and plant hormones, particularly ethylene and auxins, have been identified as important regulators of carotenoid biosynthesis during tomato fruit ripening. However, whether and how the light and hormonal signaling cascades crosstalk to control this metabolic route remain poorly elucidated. Here, the potential involvement of ethylene and auxins in the light-mediated regulation of tomato fruit carotenogenesis was investigated by comparing the impacts of light treatments and the light-hyperresponsive high pigment-2 (hp2) mutation on both carotenoid synthesis and hormonal signaling. Under either light or dark conditions, the overaccumulation of carotenoids in hp2 ripening fruits was associated with disturbed ethylene production, increased expression of genes encoding master regulators of ripening and higher ethylene sensitivity and signaling output. The increased ethylene sensitivity observed in hp2 fruits was associated with the differential expression of genes encoding ethylene receptors and downstream signaling transduction elements, including the downregulation of the transcription factor ETHYLENE RESPONSE FACTOR.E4, a repressor of carotenoid synthesis. Accordingly, treatments with exogenous ethylene promoted carotenoid biosynthetic genes more intensively in hp2 than in wild-type fruits. Moreover, the loss of HP2 function drastically altered auxin signaling in tomato fruits, resulting in higher activation of the auxin-responsive promoter DR5, severe down regulation of AUXIN/INDOLE-3-ACETIC ACID (Aux/IAA) genes and altered accumulation of AUXIN RESPONSE FACTOR (ARF) transcripts. Both tomato ARF2 paralogues (Sl-ARF2a and SlARF2b) were up-regulated in hp2 fruits, which agrees with the promotive roles played by these ARFs in tomato fruit ripening and carotenoid biosynthesis. Among the genes differentially expressed in hp2 fruits, the additive effect of light treatment and loss of HP2 function was particularly evident for those encoding carotenoid biosynthetic enzymes, ethylene-related transcription factors, Aux/IAAs and ARFs. Altogether, the data uncover the involvement of ethylene and auxin as part of the light signaling cascades controlling tomato fruit metabolism and provide a new link between light signaling, plant hormone sensitivity and carotenoid metabolism in ripening fruits. PMID- 30279696 TI - Dietary Oxidative Balance Scores and Biomarkers of Inflammation among Individuals with and without Chronic Kidney Disease. AB - Background: Oxidative stress and inflammation are proposed mechanisms of nonspecific kidney injury and progressive kidney failure. Higher dietary oxidative balance scores (OBS) are associated with lower prevalence of chronic kidney disease (CKD). Methods: We investigated the association between OBS and biomarkers of inflammation using data from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study. Nutrient estimates from the Block Food Frequency Questionnaires were used to define tertiles of 11 pro- and antioxidant factors. Points for each OBS component were summed, with a higher score indicating predominance of antioxidant exposures. Multivariable linear regression models were used to estimate the association between OBS and biomarkers of inflammation (interleukin-6 [IL-6], interleukin-8 [IL-8], interleukin-10 [IL-10], fibrinogen, C-reactive protein [CRP], white blood cell count, and cystatin C). An interaction term was included to determine if associations between OBS and inflammatory markers differed between individuals with and without CKD. Results: Of 682 participants, 22.4% had CKD. In adjusted models, OBS was associated with CRP and IL-6. For every 5-unit increase in OBS, the CRP concentration was -15.3% lower (95% CI: -25.6, -3.6). The association of OBS with IL-6 differed by CKD status; for every 5-unit increase in OBS, IL-6 was -10.7% lower (95% CI: -16.3, 4.7) among those without CKD, but there was no association among those with CKD (p = 0.03). Conclusion: This study suggests that a higher OBS is associated with more favorable levels of IL-6 and CRP, and that the association of OBS and IL-6 may be modified by CKD status. PMID- 30279697 TI - Cognitive Deficits and Associated ERP N400 Abnormalities in FXTAS With Parkinsonism. AB - Objective: To examine cognitive deficits and associated brain activity in fragile X-associated tremor/ataxia syndrome (FXTAS) patients with parkinsonism (FXTp+), in relation to FXTAS patients without parkinsonism (FXTp-), and normal elderly controls (NC). Methods: Retrospective reviews were performed in 65 FXTAS patients who participated in the event-related brain potential (ERP) study and also had either a videotaped neurological examination or a neurological examination for extrapyramidal signs. Parkinsonism was defined as having bradykinesia with at least one of the following: rest tremor, postural instability, hypermyotonia, or rigidity. Eleven FXTp+ patients were identified and compared to 11 matched FXTp- and 11 NC. Main ERP measures included the N400 congruity effect, N400 repetition effect, and the late positive component (LPC) repetition effect. Results: When compared with FXTp- and NC, the FXTp+ group showed more severe deficits in executive function, cued-recall, recognition memory, along with a significantly reduced N400 repetition effect (thought to index semantic processing and verbal learning/memory) which was correlated with poorer verbal memory. Across all patients, FMR1 mRNA levels were inversely correlated with delayed recall on the California Verbal Learning Test (CVLT). Interpretation: The findings of more prominent executive dysfunction and verbal learning/memory deficits in FXTp+ than FXTp- are consistent with findings in Parkinson's disease (PD), and may indicate that concomitant and/or synergistic pathogenetic mechanisms associated with PD play a role in FXTAS. These results have implications not only for understanding the cognitive impairments associated with the parkinsonism subtype of FXTAS, but also for the development of new interventions for these patients. PMID- 30279698 TI - Prioritized High-Confidence Risk Genes for Intellectual Disability Reveal Molecular Convergence During Brain Development. AB - Dissecting the genetic susceptibility to intellectual disability (ID) based on de novo mutations (DNMs) will aid our understanding of the neurobiological and genetic basis of ID. In this study, we identify 63 high-confidence ID genes with q-values < 0.1 based on four background DNM rates and coding DNM data sets from multiple sequencing cohorts. Bioinformatic annotations revealed a higher burden of these 63 ID genes in FMRP targets and CHD8 targets, and these genes show evolutionary constraint against functional genetic variation. Moreover, these ID risk genes were preferentially expressed in the cortical regions from the early fetal to late mid-fetal stages. In particular, a genome-wide weighted co expression network analysis suggested that ID genes tightly converge onto two biological modules (M1 and M2) during human brain development. Functional annotations showed specific enrichment of chromatin modification and transcriptional regulation for M1 and synaptic function for M2, implying the divergent etiology of the two modules. In addition, we curated 12 additional strong ID risk genes whose molecular interconnectivity with known ID genes (q values < 0.3) was greater than random. These findings further highlight the biological convergence of ID risk genes and help improve our understanding of the genetic architecture of ID. PMID- 30279700 TI - SUMO-Targeted Ubiquitin Ligases (STUbLs) Reduce the Toxicity and Abnormal Transcriptional Activity Associated With a Mutant, Aggregation-Prone Fragment of Huntingtin. AB - Cell viability and gene expression profiles are altered in cellular models of neurodegenerative disorders such as Huntington's Disease (HD). Using the yeast model system, we show that the SUMO-targeted ubiquitin ligase (STUbL) Slx5 reduces the toxicity and abnormal transcriptional activity associated with a mutant, aggregation-prone fragment of huntingtin (Htt), the causative agent of HD. We demonstrate that expression of an aggregation-prone Htt construct with 103 glutamine residues (103Q), but not the non-expanded form (25Q), results in severe growth defects in slx5Delta and slx8Delta cells. Since Slx5 is a nuclear protein and because Htt expression affects gene transcription, we assessed the effect of STUbLs on the transcriptional properties of aggregation-prone Htt. Expression of Htt 25Q and 55Q fused to the Gal4 activation domain (AD) resulted in reporter gene auto-activation. Remarkably, the auto-activation of Htt constructs was abolished by expression of Slx5 fused to the Gal4 DNA-binding domain (BD-Slx5). In support of these observations, RNF4, the human ortholog of Slx5, curbs the aberrant transcriptional activity of aggregation-prone Htt in yeast and a variety of cultured human cell lines. Functionally, we find that an extra copy of SLX5 specifically reduces Htt aggregates in the cytosol as well as chromatin associated Htt aggregates in the nucleus. Finally, using RNA sequencing, we identified and confirmed specific targets of Htt's transcriptional activity that are modulated by Slx5. In summary, this study of STUbLs uncovers a conserved pathway that counteracts the accumulation of aggregating, transcriptionally active Htt (and possibly other poly-glutamine expanded proteins) on chromatin in both yeast and in mammalian cells. PMID- 30279699 TI - Epigenetics and Metabolism in Health and Disease. AB - In the next 10 years, one billion people are estimated to suffer from disabling consequences of metabolic disorders, making them the number one noncommunicable disease on a global scale by 2030. Lots of risk factors such as dietary intake, lack of exercise and other life style behaviors are considered to play a role in the development of metabolic disorders. Despite the efforts that have been undertaken to unravel their potential causes, the underlying molecular mechanisms remain elusive. Evidence suggests that the pathogenesis involves changes on chromatin and chromatin-modifying enzymes, which can contribute to a persistent dysregulated metabolic phenotype. Indeed, a rising number of studies links epigenetic alterations with the diagnosis and prognosis of metabolic disorders. A prerequisite for exploiting these findings for pharmacological intervention is a detailed understanding of how differential epigenetic modifications control cell metabolism. In this mini review, we summarize the recent advances in uncovering the interplay between epigenetics and metabolic pathways on a cellular level and highlight potential new avenues for alternative treatment strategies.

AB - [This corrects the article DOI: 10.3389/fgene.2018.00336.]. PMID- 30279701 TI - Rapid Intraspecific Diversification of the Alpine Species Saxifraga sinomontana (Saxifragaceae) in the Qinghai-Tibetan Plateau and Himalayas. AB - An increasing number of phylogeographic studies have been conducted for plant species in the Qinghai-Tibetan Plateau (QTP) and its flanking mountains. However, these studies have mainly focused on the determination of glacial refugia and routes of inter-/post-glacial expansions. Rapid intraspecific diversification of plants in this region have not been thoroughly discussed. Herein, we investigate the effects of the Quaternary climate changes on population genetic structure and diversifications of a herbaceous alpine species, Saxifraga sinomontana, which may have an evolutionary time scale <5 million years in the QTP and Himalayan regions. Using a total of 350 individuals from 29 populations, we studied the evolutionary history of S. sinomontana by analyzing cpDNA trnL-trnF, rpl16 and nrDNA ITS sequences. A total of 89 haplotypes and 158 genotypes were detected for cpDNA and ITS sequences, respectively. Only a few haplotypes/genotypes were widespread, while an extremely large number of haplotypes/genotypes were restricted to single populations, which were scattered throughout the current geographical range of S. sinomontana. This suggests the existence of microrefugia of this species during the Quaternary glaciations. In addition, the relationships of the haplotypes/genotypes were almost completely not resolved by phylogenetic reconstruction. Combining characteristics in terms of high haplotype richness, large proportion of private haplotypes, and shallow haplotype divergence, we speculate that recent intraspecific diversification has occurred in S. sinomontana. Molecular clock analysis estimated that the onset diversification within S. sinomontana to be 1.09 Ma (95% HPD = 0.80-1.45), coinciding with the extensive Quaternary glaciations on the QTP which started ca. 1.17 Ma. The Quaternary climatic oscillations may have triggered rapid intraspecific diversification in this QTP-Himalayan species. However, large niche breadth, as well as introgression/hybridization between the studied species and its closely related sympatric saxifrages, may also played a role to some extent on the current genetic structure of S. sinomontana, which need to be further studied. PMID- 30279702 TI - Analysis of Time-Series Gene Expression Data to Explore Mechanisms of Chemical Induced Hepatic Steatosis Toxicity. AB - Non-alcoholic fatty liver disease (NAFLD) represents a wide spectrum of disease, ranging from simple fatty liver through steatosis with inflammation and necrosis to cirrhosis. One of the most challenging problems in biomedical research and within the chemical industry is to understand the underlying mechanisms of complex disease, and complex adverse outcome pathways (AOPs). Based on a set of 28 steatotic chemicals with gene expression data measured on primary hepatocytes at three times (2, 8, and 24 h) and three doses (low, medium, and high), we identified genes and pathways, defined as molecular initiating events (MIEs) and key events (KEs) of steatosis using a combination of a time series and pathway analyses. Among the genes deregulated by these compounds, the study highlighted OSBPL9, ALDH7A1, MYADM, SLC51B, PRDX6, GPAT3, TMEM135, DLGDA5, BCO2, APO10LA, TSPAN6, NEURL1B, and DUSP1. Furthermore, pathway analysis indicated deregulation of pathways related to lipid accumulation, such as fat digestion and absorption, linoleic and linolenic acid metabolism, calcium signaling pathway, fatty acid metabolism, peroxisome, retinol metabolism, and steroid metabolic pathways in a time dependent manner. Such transcription profile analysis can help in the understanding of the steatosis evolution over time generated by chemical exposure.

AB - Macrocephaly is one of the most frequent reasons for referral to a pediatric neurologist. Benign enlargement of subarachnoid space (BESS) in infancy is the most common cause of macrocephaly and characterized clinically with large head circumference, normal or mildly motor and language delay and increased cerebrospinal fluid (CSF) in the subarachnoid space with normal ventricles or mild ventriculomegaly. In this review, we describe the etiology, epidemiology, clinical presentation, pathogenesis, neuroimaging, differential diagnosis, treatment and outcome of this entity from current literature with emphasis on diagnostic work-up. PMID- 30279705 TI - The Effects of Constraint-Induced Movement Therapy on Functions of Cerebral Palsy Children. AB - Objectives: Constraint-Induced Movement Therapy (CIMT) is an intervention method that can enhance cerebral palsy (CP) children's hand function. CP is a pervasive and common disorder which affects many aspects of a child life. Hemiplegic CP affects one side of a child's hand and has great effect on child's independence. We investigated the CIMT's studies conducted in Iran, and indicated the effectiveness of CIMT on duration and children age? Materials & Methods: This systematic review was conducted using the electronic databases such as Medline PubMed, CINAHL, etc. performed from 1990 to 2016. Iranian and foreigner famous journals in the fields of pediatrics such as Iranian Journal of Pediatrics (IJP), Iranian Rehabilitation Journal (IRJ) and Google scholar with some specific keywords such as CP, CIMT, and occupational therapy were searched. Results: Overall, 43 articles were found, from which, 28 articles were removed because of lack of relevancy. Ten article were omitted because of duplication and exclusion criteria, so finally 15 articles were included. Conclusion: CIMT is effective compared to no intervention but there are some inconsistencies regarding some parts of CIMT effectiveness such as its effectiveness on muscle tone and protective extension. PMID- 30279706 TI - Clinical Trial of Efficacy Evaluation of Omega-3 with Risperidone on Seizures Frequency in Children with Refractory Epilepsy and Attention Deficit/Hyperactivity Disorder. AB - Objectives: We aimed to answer the question whether or not previous antiepileptic drugs with combination of omega-3 and risperidone are more efficient than previous antiepileptic drugs with risperidone alone in decreasing of seizures monthly frequency of children with refractory epilepsy and attention deficit/hyperactivity disorder (ADHD). Material & Methods: In a randomized clinical trial (IRCT201604212639N18), participants referred to Pediatric Neurology Clinic of Shahid Sadoughi Hospital, Yazd, Iran from Jun 2015 were distributed randomly into two groups. In group I, one capsule of omega-3 daily and 0.5 mg of risperidone was divided into two doses with previous antiepileptic drugs and in group II, 0.5 mg of risperidone was divided into two doses with previous antiepileptic drugs were given. The drugs use was continued for three months and the children were followed up monthly for three consecutive months. Primary outcomes included seizure monthly frequency and good response (more than 50% of reduction in seizures monthly frequency). Secondary outcome was clinical side effects. Results: Overall, 23 girls and 33 boys with mean age of 9.24+0.15 yr (29 children in omega-3 group and 27 children in control group) were evaluated. Omega-3 therapy was effective in decreasing of seizures monthly frequency (10.41+/-3.92 times vs. 17.01+/-4.98, P=0.03). Good response was seen in three children (11.1%) in control (95% confidence interval: 8%-22.8%) and in 9 children (31%) in omega-3 (95% CI: 47.83%-14.17%) group, which showed that omega 3 was more effective in seizure control. (P=0.001). Frequency of side effects was not different in the two groups (14.8 % in control vs. 20.7% in omega-3 groups, P=0.5). Conclusion: Omega-3 might be used as an effective and safe drug in seizures control of children with refractory epilepsy and ADHD. PMID- 30279707 TI - Autistic Children Are More Responsive to Tactile Sensory Stimulus. AB - Objective: This research was an experimental study that was aimed to detect differences response of tactile sensory stimulus between normal children and children with sensory brain development disorders such as Autism Spectrum Disorder (ASD). Materials & Methods: A total of 134 children, in two groups including 67 healthy children (control) and 67 children with autism were studied. Tactile sensory stimulus responses in children were tested directly using a Reflex Hammer. In addition, tactile sensory sensitivity was also assessed via questionnaire Short Sensory Profile (SSP) filled out by the child's parents. All response data were analyzed using Fisher's Exact Test; questionnaire data was analyzed with the Mann-Whitney U Test. Results: Autistic children were more sensitive to palpation and pain than children who were not autistic. Furthermore, the value of SSP was also significantly higher (P<0.05) in autistic children, which means that they always responded to all categories in the SSP questionnaire than children who are not autistic. Conclusion: Autistic children are more sensitive to tactile sensory stimulus and all categories of SSP than children who are not autistic. PMID- 30279708 TI - Comparison of the Quality of Sleep and Intensity of Headache between Migraine, Tension Headache, and Healthy Children. AB - Objectives: Headache and sleep problems are commonly reported in children, and both can adversely impact the child's life. We aimed to compare the sleep quality and intensity of headache between school-age children with migraine as well as tension headache and healthy children. Materials & Methods: In this cross sectional study, 198 children 6-12 yr old in three groups were enrolled from Aug 2015 to Mar 2016. Migraine and tension headache groups from the Outpatient Clinic of Imam Khomeini of Hamadan, western Iran and healthy group from elementary schools were randomly selected (66 children in each group). Data were collected using demographic questionnaire, Child Sleep Habits Questionnaire (CSHQ), Numeric Scale of Pain Intensity and Wong-Baker Faces Pain Rating Scale. The data were analyzed using SPSS by descriptive statistic and multivariate ANOVA, one way ANOVA, Chi-square, Kruskal-Wallis and linear regression tests. Results: Approximately, 45.5% of children with migraine and 37.9% of them with tension headache had experienced severe headache. Only a significant relationship was seen between mean scores of headache intensity and sleep quality in migraine group (P<0.05). There was a significant difference in mean scores of sleep quality among three groups (P<0.001). Conclusion: The children with migraine experienced more unsuitable sleep in duration of severe headache. Highlighting the co-morbidity between intensity of headache and sleep problem of children with migraine and tension headache is important to improve treatment strategies and to know the impact of headache on their normal life. PMID- 30279709 TI - The Effect of Non-Nutritive Sucking and Maternal Milk Odor on the Independent Oral Feeding in Preterm Infants. AB - Objectives: Given the positive effects of stimulation with breast milk odor and non-nutritive sucking (NNS) on preterm feeding skills, we examined the effect of NNS and milk odor, on the time of achieving independent oral feeding in preterm infants. Materials & Methods: This study was conducted at two Neonatal Intensive Care Units of Tehran, Iran in 2016. Overall, 32 neonates with gestational ages of 28-32 wk were enrolled in two groups; NNS with and without olfactory stimuli (breast milk odor). The simulations were performed in both groups during the first five minutes of gavage, three times per day, and over ten consecutive days. Weight gain, time of achieving oral feeding and chronological age at discharge were as measures of the effectiveness of the interventions. The results of the interventions were analyzed and compared using SPSS.18. Results: NNS with breast milk odor resulted to a lower post-menstrual age at the first oral feeding, independent oral feeding and discharge from the hospital, but had no effects on their daily weight gain and weight at the time of discharge. Conclusion: These results show the effectiveness of combining milk odor and NNS as two important stimuli in achieving oral feeding and earlier discharge from the hospital. PMID- 30279710 TI - A Web-Based Caring Training for Caregivers of Children with Cerebral Palsy: Development and Evaluation. AB - Objectives: Caregivers of children with cerebral palsy (CP) have to spend a long time to take care of their children. We aimed to develop a user-friendly web based intervention for training parents of children with CP and evaluate the process of development using modified CeHRes roadmap. Materials & Methods: The study was conducted from September 2016 to September 2017 in Tehran, Iran. We did it in four main steps including determining the needs of users, content development, design, operational development and evaluation. Results: The website for caregiver training provided nine general topics and had the possibility that the caregivers could determine their educational priorities. Moreover, the users could share their experiences with other users and could ask questions from an expert. Ten caregivers completed a usability questionnaire after four weeks of use. The average score of 70.5 out of 100 was shown among caregivers. The average score of all statements was above three on a Likert scale between 1 and 5. Conclusion: The website has the possibilities including registering caregivers of children with CP, the possibility to confirm registration with an SMS and the possibility to determine the caregiver educational priorities. It has the usability for training caregivers of children with CP. PMID- 30279711 TI - Comparison of the Effect of Phenobarbital versus Sodium Valproate in Management of Children with Status Epilepticus. AB - Objectives: Acute prolonged seizure is the most common neurological emergency in children. This research was conducted to compare the effect of intravenous phenobarbital and Sodium valproate in control of seizure in children with status epilepticus, referred to emergency ward from Mar to Nov 2013. Materials & Methods: In this randomized clinical trial, registered with the code number IRCT2015051722300N1, 80 children aged 6 months to 10 years with prolonged seizure and with no response to one dose of diazepam (0.2 mg/kg) administered through IV injection during the five min were selected. Children were randomly divided into two groups, intervention, and control through permutation blocks. In intervention group, intravenous Sodium valproate (20 mg/kg) and in control group, intravenous phenobarbital (20 mg/kg) were prescribed. Data such as age, gender, history of previous seizure, seizure type, and recovery time after receiving drug was recorded in the form. Data analysis was done through descriptive statistics, Chi square and Independent t- test. Results: Two groups were the same in terms of age and gender and had no statistically significant difference, but they were different in terms of seizure type. In valproate group, 18 patients (45%) and in phenobarbital group, 32 patients (80%) had positive response to the treatment and the chi-square test showed the significant difference. Conclusion: With regards to this point that in phenobarbital group, patients had more rapid response to drug in comparison with patients in Sodium valproate group, phenobarbital is a suitable and effective drug for controlling of seizure in children. PMID- 30279712 TI - Goodenough-Harris Drawing a Man Test (GHDAMT) as a Substitute of Ages and Stages Questionnaires (ASQ2) for Evaluation of Cognition. AB - Objective: The main aim of the current research was evaluation of concurrent validity of the Goodenough-Harris Draw-A-Man Test (GHDAMT) with the problem solving subscale of ASQ2 among children between 54-60 months old in Tabriz City, northwestern Iran. Materials & Methods: In this cross-sectional study, 136 males and 105 females were selected by simple random sampling from nursery schools in Tabriz City, northwestern Iran in 2014 and tested with GHDAMT and ASQ2 to compare the concurrent validity of these tests in evaluation of cognition. Data were analyzed using Pearson or Spearman correlation coefficients and SPSS.16. Results: The mean Intelligence Quotient (IQ) in girls was 128+/-18.18 and in boys 118+/ 18.50, and the difference was statistically significant P<0.001. There was no statistically significant correlation between GHDAMT and ASQ2 .The statistical correlation was significant between IQ and mental age among children who had -2SD score in problem-solving subscale, but there was no statistical correlation between children who had -1SD score P<0.002. There was no statistically significant correlation between problem-solving subscale of ASQ2 and mental age and IQ. Conclusion: GHDAMT did not have acceptable validity and concurrent validity of the test was less than 0.3. So GHDAMT cannot be used as a substitute of ASQ questionnaire. However, the correlation of two tests in children with intellectual and developmental disability was significant. After doing more studies in further research, it is possible to use GHDAMT as a proper tool for cognition evaluation of these children. PMID- 30279713 TI - Oral Levetiracetam as Add-On Therapy in Refractory Neonatal Seizures. AB - Objective: Seizure is the most common signs of nervous system disease in neonates. The first line of treatments in neonatal seizures (after ruling out and emergency treatment of electrolyte imbalance and hypoglycemia) are phenobarbital and phenytoin. We aimed to evaluate drugs that are more effective on neonatal seizure. Materials & Methods: Patients admitted to neonatal wards & NICUs (level IIa& IIb) in Qom hospitals (2015-2017), central Iran with presentation of seizure, were enrolled in this clinical trial study. After ruling out electrolyte imbalance and hypoglycemia these neonates were managed by intravenous phenobarbital, then if no response was seen we added intravenous phenytoin and for remaining neonates with refractory seizure we applied oral levetiracetam as add on therapy. The study was registered as code number of IRCT2016051527896N1. Results: Initially, 245 neonates were enrolled. According to exclusion criteria, 12 cases were excluded, and phenobarbital was prescribed to the remaining patients. Out of these, 86 patients did not respond, and phenytoin was prescribed for them. Forty two patients who were not responding to phenytoin were finally treated with oral levetiracetam. Finally, 95.3% of seizures were controlled with oral levetiracetam but 4.7% were not cured. Conclusion: When the intravenous form of levetiracetam is not available and neonatal seizure does not respond to first line classic drugs, oral levetiracetam as add on therapy maybe effective. PMID- 30279714 TI - A Novel Splice Site Mutation of the ATM Gene Associated with Ataxia Telangiectasia. AB - Objectives: Ataxia telangiectasia (AT) is a rare autosomal recessive disorder caused by mutation in the Ataxia telangiectasia mutated (ATM) gene. This disorder is characterized by progressive cerebellar ataxia, telangiectasia, immunodeficiency and a predisposition to leukemia/lymphoma. In this study, we investigated a family with a new mutation in ATM, confirmed by molecular genetic test. Materials&Methods: Four members of a family including a symptomatic AT patient, his parents and sibling were examined for ATM gene defects at Kerman University Hospital, Kerman, Iran in 2016. DNA was extracted from peripheral leukocytes and the coding regions and exon-intron boundaries of ATM gene were amplified by next-generation sequencing technique. The identified mutation was tested in all members of the family. Results: Molecular analyses identified a homozygous T to G substitution in c.7308-6 position resulting in a novel acceptor splice site in intron 49 of the ATM gene in the index patient. Parents and sibling of the proband were heterozygous for the same mutation. Conclusion: The variant c.7308-6T>G is predicted to be pathogenic due to impaired splice site causing exon skipping. This newly found frameshift mutation cosegregated as an autosomal recessive trait as expected for Ataxia telangiectasia syndrome. PMID- 30279715 TI - The Relation between Urinary Tract Infection and Febrile Seizure. AB - Objectives: Febrile seizure is the most common type of seizure among children. Identification of factors involved in febrile seizure is highly critical. The present study was conducted to determine the association between children's urinary tract infection and febrile seizure. Materials & Methods: In this case control study, 165 children with simple febrile seizure (case group) were compared with 165 children with fever and without seizure (control group) in terms of urinary tract infection (UTI) in Qazvin, central Iran in 2015-2016. The age of children was between 6 months to 5 yr. Results: Among 165 children with febrile seizure, 25 (15.2%) had urinary tract infection. In the control group, only 2 patients (1.2%) had UTI. There was significant difference between two groups regarding urinary tract infection (P=0.001). Among 25 children with UTI in the case group, 17 children (68%) had acute pyelonephritis, and the remaining 8 children (32%) had cystitis. The two patients with UTI in control group had cystitis (P=0.055). Conclusion: Urinary tract infection could be a risk factor for febrile seizure. Therefore, all patients with febrile seizure are examined in terms of urinary tract infection. PMID- 30279716 TI - A look at the normal development of Pointing and Reaching Gestures in 12-16-Month Old Farsi-Speaking Children: A Longitudinal Study. AB - Objectives: Human beings can use gestures such as pointing and reaching to communicate with others before they have the ability to use verbal communication to produce speech. Given the importance of children's communication development and the key role of gestures development in communicating, the main purpose of this study was to analyze the normal development of pointing and reaching gestures and their relationship in 12-16-month-old children speaking Farsi. Materials & Methods: In this prospective, observational and longitudinal study the gestures of 11 monolingual Farsi-speaking children (7 boys and 4 girls, from Oct 2015 to Jan 2017 in the homes of participants across Tehran, Iran) were evaluated via non-randomized sampling method. Child-mother interactions were videotaped monthly in a semi-structured context to capture the emergence and consistent use of targeted gestures. Afterward, the data were coded and statistically analyzed for this purpose Repetitive measured; independent t-test and Pearson correlation were used. Results: The mean of the pointing gesture increased significantly from 12 to 16 months (P<0.05). However, this was not significant for the reaching gesture. Moreover, there was no relationship between pointing and reaching gestures. Conclusion: Pointing gestures increase with age from 12-16 months in Farsi-speaking children. However, reaching gestures stay the same between 12-16 months of age. The study provided rich details of common gestures that children use to signal their intentions before verbal communication. PMID- 30279717 TI - The Relationship between Emotional Content and Word Processing in Normal Persian Speaking Children. AB - Objectives: Emotion is a key component in language processing, but emotional words processing in children is still controversial. We aimed to investigate the relationship between emotional dimensions, arousal and valence, word familiarity, comprehension, use, and emotional content recognition. Eventually, a list of emotional content words for this age was prepared in Persian. Materials&Methods: The study was conducted in selected elementary schools in Tehran, Iran from April to June 2017. Emotional words, from adult emotional words list, were categorized into 5 groups according to their arousal and valence scores, including neutral, happy, calm, anxious and sad. Evaluation of familiarity, use, comprehension and emotional content recognition of the list was conducted with a checklist in 60 first grade children by speech and language pathologist. Results: Neutral words gained the highest score in familiarity, use, comprehension and emotional content recognition (the mean=0.74). Afterward, there were the emotional words with high valence, calm (the mean=0.64) and happy (the mean=0.52). Finally, it was found the low score for valence emotional words, sad (the mean=0.46) anxious (the mean =0.43) in end of score rating. There was a significant difference between all word groups in four aspects (P-value<0.001). There were no significant differences between boys and girls in four aspects. Conclusion: Neutral words are better comprehended and expressed than emotional words. Valence is more effective than arousal in emotional words. Gender was not a determinant factor in all of the aspects. An emotional word list which is comprehensible for children in Persian language was prepared. PMID- 30279718 TI - Risk Factors for Hearing Loss and Its Prevalence in Neonates Older than 6 Months with History of Hospitalization in Intensive Care Unit. AB - Objectives: Hearing loss is one of the most important disabilities in neonates. Delay in the detection of hearing loss leads to impaired development and may prevent the acquisition of speech. We aimed to determine the risk factors associated with hearing loss in neonatal patients aged more than 6 months with a history of hospitalization in Neonatal Intensive Care Unit (NICU). Methods: In this case-control study, screening for hearing loss was carried out on 325 neonates aged 6-12 months referred to Pediatric Neurology Office of Vali-e-Asr Hospital, Tehran, Iran up to 2011. Hearing loss was confirmed using Auditory Brainstem Response screening test (ABR). Results: The prevalence of mildly and moderately hearing loss in neonates was determined as 3.6%. The most significant risk factors for hearing loss in neonates were neonatal icterus associated with phototherapy, respiratory distress syndrome (RDS) and lower Apgar score. Conclusion: It seems to quantitative auditory system screening using ABR is necessary for all neonates; because rehabilitation support such as speech therapy and hearing training in this age period is more effective than older ages.

Although untreatable, it can be prevented by appropriate prenatal diagnostic tests for their future children. PMID- 30279720 TI - Enterobacter Meningitis Due To Dermoid Cyst Manipulation. AB - Gram-negative meningitis can occurssubsequent to dura-arachnoid barrier disruption because of trauma, surgery and rarely an infected dermoid cyst. Association of neurosurgical procedures with Gram-negative meningitis was described for the first time in 1940. Intracranial infections from gram-negative bacilli like Enterobacter are serious and difficult to treat as many antibiotics fail to achieve bactericidal concentrations in the cerebrospinal fluid. Here in, we report a rare case of pediatric Enterobacter meningitis in a patient with a dermoid cyst that had been manipulated. She was managed with antibiotic therapy plus surgical removal of the infected cyst. PMID- 30279721 TI - Offspring dependence on parental care and the role of parental transfer of oral fluids in burying beetles. AB - Background: Immature stages of many animals can forage and feed on their own, whereas others depend on their parents' assistance to obtain or process food. But how does such dependency evolve, and which offspring and parental traits are involved? Burying beetles (Nicrophorus) provide extensive biparental care, including food provisioning to their offspring. Interestingly, there is substantial variation in the reliance of offspring on post-hatching care among species. Here, we examine the proximate mechanisms underlying offspring dependence, focusing on the larvae of N. orbicollis, which are not able to survive in the absence of parents. We specifically asked whether the high offspring dependence is caused by (1) a low starvation tolerance, (2) a low ability to self-feed or (3) the need to obtain parental oral fluids. Finally, we determined how much care (i.e. duration of care) they require to be able to survive. Results: We demonstrate that N. orbicollis larvae are not characterized by a lower starvation tolerance than larvae of the more independent species. Hatchlings of N. orbicollis are generally able to self-feed, but the efficiency depends on the kind of food presented and differs from the more independent species. Further, we show that even when providing highly dependent N. orbicollis larvae with easy ingestible liquefied mice carrion, only few of them survived to pupation. However, adding parental oral fluids significantly increased their survival rate. Finally, we demonstrate that survival and growth of dependent N. orbicollis larvae is increased greatly by only a few hours of parental care. Conclusions: Considering the fact that larvae of other burying beetle species are able to survive in the absence of care, the high dependence of N. orbicollis larvae is puzzling. Even though they have not lost the ability to self-feed, an easily digestible, liquefied carrion meal is not sufficient to ensure their survival. However, our results indicate that the transfer of parental oral fluids is an essential component of care. In the majority of mammals, offspring rely on the exchange of fluids (i.e. milk) to survive, and our findings suggest that even in subsocial insects, such as burying beetles, parental fluids can significantly affect offspring survival. PMID- 30279722 TI - Improved secretory expression of lignocellulolytic enzymes in Kluyveromyces marxianus by promoter and signal sequence engineering. AB - Background: Taking into account its thermotolerance, high growth rate, and broad substrate spectrum, Kluyveromyces marxianus can be considered an ideal consolidated bioprocessing (CBP). A major obstacle to ethanol production using K. marxianus is the low production of lignocellulolytic enzymes, which reduces the cellulose hydrolysis and ethanol production. Thus, further improvement of enzyme expression and secretion is essential. Results: To improve the expression of lignocellulolytic enzymes, the inulinase promoter and signal sequence from K. marxianus was optimized through mutagenesis. A T(-361)A mutation inside the promoter, a deletion of AT-rich region inside 5'UTR (UTR?A), and a P10L substitution in the signal sequence increased the secretory expression of the feruloyl esterase Est1E by up to sixfold. T(-361)A and UTR?A increased the mRNA expression, while the P10L substitution extended the hydrophobic core of signal sequence and promoted secretion of mature protein. P10L and T(-361)A mutations increased secretory expressions of other types of lignocellulolytic enzymes by up to threefold, including endo-1,4-beta-glucanase RuCelA, endo-1,4-beta endoxylanase Xyn-CDBFV, and endo-1,4-beta-mannanase MAN330. During the fed-batch fermentation of strains carrying optimized modules, the peak activities of RuCelA, Xyn-CDBFV, MAN330, and Est1E reached 24 U/mL, 25,600 U/mL, 10,200 U/mL, and 1220 U/mL, respectively. Importantly, higher yield of enzymes by optimized promoter and signal sequence were achieved in all tested carbon sources, including the major end products of lignocellulose saccharification and fermentation, with growth on xylose resulting in the highest production. Conclusions: The engineered promoter and signal sequence presented increased secretory expressions of different lignocellulolytic enzymes in K. marxianus by means of various carbon resources. Activities of lignocellulolytic enzymes in fed batch fermentation were the highest activities reported for K. marxianus so far. Our engineered modules are valuable in producing lignocellulolytic enzymes by K. marxianus and in constructing efficient CBP strains for cellulosic ethanol production. PMID- 30279723 TI - Combination of NIR therapy and regulatory T cell modulation using layer-by-layer hybrid nanoparticles for effective cancer photoimmunotherapy. AB - The efficacy of combined near-infrared (NIR) and immune therapies for inhibiting tumor growth and recurrence has gained increasing research attention. Regulatory T cells in the tumor microenvironment constitute a major obstacle in achieving robust CD8+ T cell antitumor immunotherapy. In the present study, we designed a photoimmunotherapy-based strategy involving a combination of photothermal and photodynamic therapies, followed by Treg cell suppression, for eliciting an immune response with IR-780- and imatinib-loaded layer-by-layer hybrid nanoparticles. Methods: The layer-by-layer hybrid nanoparticles were prepared through electrostatic interactions. Their photothermal effect, photodynamic effect as well as their effect on inhibiting Treg cells' suppressive function were investigated in vitro and in vivo. Their antitumor effect was evaluated using B16/BL6 and MC-38 tumor-bearing mice. Results: The layer-by-layer hybrid nanoparticles, which were pH-sensitive, enabled the release of IR-780 dye for NIR induced photothermal and photodynamic effects, and the release of imatinib-loaded glucocorticoid-induced TNF receptor family-related protein/poly(lactic-co glycolic acid) (GITR-PLGA) nanoparticles to initiate antitumor immunotherapy. The photothermal and photodynamic effects caused by IR-780 under NIR exposure resulted in direct tumor apoptosis/necrosis and the production of tumor associated antigen, promoted dendritic cell maturation, and enhanced the presentation of tumor-associated antigen to T cells, while the imatinib-loaded GITR-PLGA cores reduced the suppressive function of Treg cells, and consequently activated effective CD8+ T cells towards tumors. Conclusion: With the significant photothermal, photodynamic and immunotherapies, the system successfully eradicated tumor growth, diminished tumor recurrence, and improved survival in vivo. The proposed nanoparticles provide a novel and versatile approach to boost antitumor photoimmunotherapy. PMID- 30279724 TI - Radiopaque and uniform alginate microspheres loaded with tantalum nanoparticles for real-time imaging during transcatheter arterial embolization. AB - One restriction to the development and application of transcatheter arterial chemoembolization (TACE) therapy is the lack of an inherently radiopaque embolic whose location and distribution can be precisely visualized in real time and be used for non-invasive examination after surgery. Methods: A one-step electrospray method was developed to fabricate calcium alginate microspheres loaded with tantalum nanoparticles (Ta@CaAlg). The parameters of electrospraying were assessed. The in vivo X-ray imaging capability and embolic effect of Ta@CaAlg microspheres were evaluated in the renal arteries of normal rabbits by digital radiography and computed tomography. Doxorubicin hydrochloride (Dox) was chosen as a model drug, and the drug loading capacity and release behavior of these microspheres was valuated in vitro. Results: Spherical Ta@CaAlg microspheres with monodisperse sizes ranging from 150 to 1200 MUm were fabricated by electrospraying. The results of an in vivo study showed that Ta@CaAlg microspheres possessed the qualities of both embolic agents and contrast media. They could not only feed back the real-time location and distribution of the embolic microspheres but also maintained clear X-ray imaging of embolized sites for up to 4 weeks as assessed by digital radiography and computed tomography. Digital subtraction angiography showed that they had an excellent embolic effect. Ta@CaAlg microspheres could be loaded with Dox to form "3-in-1" embolic microspheres. The maximum Dox loading was 97.3 mg Dox per mL beads and loaded microspheres exhibited pH-dependent release profiles. Conclusion: The X-ray opacity and drug-loading capability of Ta@CaAlg microspheres offers great promise in direct, real-time, in vivo investigation for TACE and long-term non-invasive re-examination. PMID- 30279725 TI - Erratum: Early Assessment of Tumor Response to Radiation Therapy using High Resolution Quantitative Microvascular Ultrasound Imaging: Erratum. AB - [This corrects the article DOI: 10.7150/thno.19703.]. PMID- 30279726 TI - ATP-activated decrosslinking and charge-reversal vectors for siRNA delivery and cancer therapy. AB - Stimuli-responsive polycations have been developed for improved nucleic acid transfection and enhanced therapeutic efficacy. The most reported mechanisms for controlled release of siRNA are based on polyelectrolyte exchange reactions in the cytoplasm and the degradation of polycations initiated by specific triggers. However, the degradation strategy has not always been sufficient due to unsatisfactory kinetics and binding of cationic fragments to siRNA, which limits the gene silencing effect. In this study, a new strategy that combines degradation and charge reversal is proposed. Methods: We prepared a polycation (CrossPPA) by crosslinking of phenylboronic acid (PBA)-grafted 1.8k PEI with alginate. It was compared with 25k PEI, 1.8k PEI and 1.8k PEI-PBA on siRNA encapsulation, ATP-responsive behavior and mechanism, cytotoxicity, cell uptake, siRNA transfection, in vivo biodistribution and in vivo anti-tumor efficacy. The in vitro and in vivo experiments were performed on 4T1 murine breast cancer cells and 4T1 tumor model separately. Results: The crosslinking strategy obviously improve the siRNA loading ability of 1.8k PEI. We validated that intracellular levels of ATP could trigger CrossPPA disassembly and charge reversal, which resulted in efficient and rapid siRNA release due to electrostatic repulsion. Besides, CrossPPA/siRNA showed strong cell uptake in 4T1 cells compared with 1.8k PEI/siRNA. Notably, the cytotoxicity of CrossPPA was pretty low, which was owing to its biodegradability. Furthermore, the crosslinked polyplexes significantly enhanced siRNA transfection and improved tumor accumulation. The high gene silencing ability of CrossPPA polyplex led to strong anti-tumor efficacy when using Bcl2-targeted siRNA. Conclusion: These results indicated that the ATP triggered disassembly and charge reversal strategy provided a new way for developing stimuli-responsive siRNA carriers and showed potential for nucleic acid delivery in the treatment of cancer. PMID- 30279727 TI - Senescent fibroblasts drive ageing pigmentation: A potential therapeutic target for senile lentigo. AB - Cutaneous ageing is an important extrinsic process that modifies the pigmentary system. Because cellular senescence is a fundamental ageing mechanism, we examined the role of senescent cells in ageing pigmentation. Methods: Biopsies obtained from senile lentigo and perilesional normal skin were assayed for a marker of cellular senescence, p16INK4A. To determine the secretory phenotypes of senescent fibroblasts, we performed microarray, RNA sequencing and methylation array analyses in senile lentigo and senescent fibroblasts. To further investigate the impact of senescent cells on ageing-related pigmentation, an intervention that targeted senescent cells using radiofrequency was performed. Results: In vivo, senescent fibroblasts accumulated at the sites of age-related pigmentation. Phenotype switching of the cells resulted in the repression of stromal-derived factor 1 (SDF1) by promoter methylation. SDF1 induced melanocyte differentiation via stromal-epithelial interactions, ultimately driving skin pigmentation. Furthermore, the elimination of senescent fibroblasts from pigmented skin using radiofrequency was accompanied by skin lightening, rendering it a potential target for treatment. Conclusion: Aged pigmented skin contains an increasing proportion of senescent fibroblasts. Cells with phenotype switching exhibited a loss of SDF1, which stimulates the melanogenic process and thereby contributes to aging pigmentation. These data may promote the development of new therapeutic paradigms, such as a stroma-targeting therapy for pigmentary disorders. PMID- 30279728 TI - Aphthous ulcer drug inhibits prostate tumor metastasis by targeting IKKE/TBK1/NF kappaB signaling. AB - Tumor metastasis is the major cause of death for prostate cancer (PCa) patients. However, the treatment options for metastatic PCa are very limited. Epithelial mesenchymal transition (EMT) has been reported to be an indispensable step for tumor metastasis and is suggested to associate with acquisition of cancer stem cell (CSC) attributes. We propose that small-molecule compounds that can reverse EMT or induce mesenchymal-epithelial transition (MET) of PCa cells may serve as drug candidates for anti-metastasis therapy. Methods: The promoters of CDH1 and VIM genes were sub-cloned to drive the expression of firefly and renilla luciferase reporter in a lentiviral vector. Mesenchymal-like PCa cells were infected with the luciferase reporter lentivirus and subjected to drug screening from a 1274 approved small-molecule drug library for the identification of agents to reverse EMT. The dosage-dependent effect of candidate compounds was confirmed by luciferase reporter assay and immunoblotting. Wound-healing assay, sphere formation, transwell migration assay, and in vivo intracardiac and orthotopic tumor xenograft experiments were used to evaluate the mobility, metastasis and tumor initiating capacity of PCa cells upon treatment. Possible downstream signaling pathways affected by the candidate compound treatment were analyzed by RNA sequencing and immunoblotting. Results: Drug screening identified Amlexanox, a drug used for recurrent aphthous ulcers, as a strong agent to reverse EMT. Amlexanox induced significant suppression of cell mobility, invasion, serial sphere formation and in vivo metastasis and tumor initiating capacity of PCa cells. Amlexanox treatment led to downregulation of the IKK-E/ TBK1/ NF-kappaB signaling pathway. The effect of Amlexanox on EMT reversion and cell mobility inhibition can be mimicked by other IKK-E/TBK1 inhibitors and rescued by reconstitution of dominant active NF-kappaB. Conclusions: Amlexanox can sufficiently suppress PCa metastasis by reversing EMT through downregulating the IKK-E/TBK1/NF-kappaB signaling axis. PMID- 30279729 TI - Hypoxia-induced up-regulation of VASP promotes invasiveness and metastasis of hepatocellular carcinoma. AB - Rational: Patients with hepatocellular carcinoma (HCC) have a poor prognosis mostly due to intrahepatic as well as distal metastasis. Vasodilator-stimulated phosphoprotein (VASP), a regulator of actin cytoskeleton and cell migration, is overexpressed in HCC and correlated with its malignant features and poor prognosis. Very little is known about its function in HCC. Methods: qRT-PCR, Western blot and IHC were used to detect the VASP expression in tissues and cells. Transwell and wound healing assays were used to measure the migration and invasion of HCC cells. Immunoblotting and immunofluorescence were used for detection of epithelial-to-mesenchymal transition (EMT) progression in HCC cells. A lung metastasis mouse model was used to evaluate metastasis of HCC in vivo. The putative targets of miR-204 were disclosed by public databases and a dual luciferase reporter assay. IP was used to show the interaction between VASP and CRKL. ChIP was used to analyze the binding of HIF-1alpha to VASP promoter region. Results: Our data involving both gain- and loss-of-function studies revealed that VASP activated AKT and ERK signaling and promoted HCC migration and invasion in vitro and in vivo by altering the EMT phenotype and expression of MMPs. We investigated the positive correlation between VASP and an adapter protein, CRKL. VASP dynamically co-localized at the SH3N domain of CRKL and mediated its function. Mechanistically, VASP overexpression at the transcriptional level was mediated by HIF-1alpha through direct binding to two hypoxia response elements (HRE) in the VASP promoter region. Furthermore, we identified hypoxia-induced down-regulation of miR-204, which functioned as the regulator of VASP overexpression at the post-transcriptional level. Also, hypoxia-activated p-Smad3 dependent TGF-beta signaling indirectly promoted VASP expression. Conclusion: A variety of hypoxia-induced molecular mechanisms contributed to the upregulation of VASP at transcriptional and post-transcriptional levels. These mechanisms involved CRKL, HIF-1alpha, miR-204, and TGF-beta activating the AKT and ERK signaling to promote EMT and expression of MMPs. Taken together, our results defined VASP as an oncogene of HCC pathogenesis and metastasis with the potential to serve as a prognostic biomarker. PMID- 30279730 TI - Pepducin-mediated cardioprotection via beta-arrestin-biased beta2-adrenergic receptor-specific signaling. AB - Reperfusion as a therapeutic intervention for acute myocardial infarction-induced cardiac injury itself induces further cardiomyocyte death. beta-arrestin (betaarr)-biased beta-adrenergic receptor (betaAR) activation promotes survival signaling responses in vitro; thus, we hypothesize that this pathway can mitigate cardiomyocyte death at the time of reperfusion to better preserve function. However, a lack of efficacious betaarr-biased orthosteric small molecules has prevented investigation into whether this pathway relays protection against ischemic injury in vivo. We recently demonstrated that the pepducin ICL1-9, a small lipidated peptide fragment designed from the first intracellular loop of beta2AR, allosterically engaged pro-survival signaling cascades in a betaarr dependent manner in vitro. Thus, in this study we tested whether ICL1-9 relays cardioprotection against ischemia/reperfusion (I/R)-induced injury in vivo. Methods: Wild-type (WT) C57BL/6, beta2AR knockout (KO), betaarr1KO and betaarr2KO mice received intracardiac injections of either ICL1-9 or a scrambled control pepducin (Scr) at the time of ischemia (30 min) followed by reperfusion for either 24 h, to assess infarct size and cardiomyocyte death, or 4 weeks, to monitor the impact of ICL1-9 on long-term cardiac structure and function. Neonatal rat ventricular myocytes (NRVM) were used to assess the impact of ICL1-9 versus Scr pepducin on cardiomyocyte survival and mitochondrial superoxide formation in response to either serum deprivation or hypoxia/reoxygenation (H/R) in vitro and to investigate the associated mechanism(s). Results: Intramyocardial injection of ICL1-9 at the time of I/R reduced infarct size, cardiomyocyte death and improved cardiac function in a beta2AR- and betaarr-dependent manner, which led to improved contractile function early and less fibrotic remodeling over time. Mechanistically, ICL1-9 attenuated mitochondrial superoxide production and promoted cardiomyocyte survival in a RhoA/ROCK-dependent manner. RhoA activation could be detected in cardiomyocytes and whole heart up to 24 h post-treatment, demonstrating the stability of ICL1-9 effects on betaarr-dependent beta2AR signaling. Conclusion: Pepducin-based allosteric modulation of betaarr-dependent beta2AR signaling represents a novel therapeutic approach to reduce reperfusion induced cardiac injury and relay long-term cardiac remodeling benefits. PMID- 30279731 TI - Dopaminergic precursors differentiated from human blood-derived induced neural stem cells improve symptoms of a mouse Parkinson's disease model. AB - Autologous neural stem cells (NSCs) may offer a promising source for deriving dopaminergic (DA) cells for treatment of Parkinson's disease (PD). Methods: By using Sendai virus, human peripheral blood mononuclear cells (PBMNCs) were reprogrammed to induced NSCs (iNSCs), which were then differentiated to dopaminergic neurons in vitro. Whole-genome deep sequencing was performed to search for mutations that had accumulated during the reprogramming and expansion processes. To find the optimal differentiation stage of cells for transplantation, DA precursors obtained at various differentiation time points were tested by engraftment into brains of naive immunodeficient mice. At last, the safety and efficacy of iNSC-derived DA precursors were tested by transplantation into the striatum of immunodeficient PD mouse models. Results: PBMNC-derived iNSCs showed similar characteristics to fetal NSCs, and were able to specifically differentiate to DA neurons with high efficiency in vitro. The sequencing data proved that no harmful SNVs, Indels and CNVs were generated during the reprogramming and expansion processes. DA precursors obtained between differentiation day 10 to 13 in vitro were most suitable for transplantation when a balanced graft survival and maturation were taken into account. Two weeks after transplantation of DA precursors into mouse PD models, the motor functions of PD mice started to improve, and continued to improve until the end of the experiments. No graft overgrowth or tumor was observed, and a significant number of A9-specific midbrain DA neurons were surviving in the striatum. Conclusion: This study confirmed the efficacy of iNSC-derived DA precursors in a mouse PD model, and emphasized the necessity of genomic sequencing and vigorous safety assessment before any clinical translation using iNSCs. PMID- 30279732 TI - Galphai1 and Galphai3mediate VEGF-induced VEGFR2 endocytosis, signaling and angiogenesis. AB - VEGF binding to VEGFR2 leads to VEGFR2 endocytosis and downstream signaling activation to promote angiogenesis. Methods: Using genetic strategies, we tested the requirement of alpha subunits of heterotrimeric G proteins (Galphai1/3) in the process. Results: Galphai1/3 are located in the VEGFR2 endocytosis complex (VEGFR2-Ephrin-B2-Dab2-PAR-3), where they are required for VEGFR2 endocytosis and downstream signaling transduction. Galphai1/3 knockdown, knockout or dominant negative mutation inhibited VEGF-induced VEGFR2 endocytosis, and downstream Akt mTOR and Erk-MAPK activation. Functional studies show that Galphai1/3 shRNA inhibited VEGF-induced proliferation, invasion, migration and vessel-like tube formation of HUVECs. In vivo, Galphai1/3 shRNA lentivirus inhibited alkali burn induced neovascularization in mouse cornea. Further, oxygen-induced retinopathy (OIR)-induced retinal neovascularization was inhibited by intravitreal injection of Galphai1/3 shRNA lentivirus. Moreover, in vivo angiogenesis by alkali burn and OIR was significantly attenuated in Galphai1/3 double knockout mice. Significantly, Galphai1/3 proteins are upregulated in proliferative retinal tissues of proliferative diabetic retinopathy (PDR) patients. Conclusion: These results provide mechanistic insights into the critical role played by Galphai1/3 proteins in VEGF-induced VEGFR2 endocytosis, signaling and angiogenesis. PMID- 30279733 TI - Nanoparticles for diagnosis and therapy of atherosclerosis and myocardial infarction: evolution toward prospective theranostic approaches. AB - Cardiovascular diseases are the leading cause of death worldwide. Despite preventive efforts, early detection of atherosclerosis, the common pathophysiological mechanism underlying cardiovascular diseases remains elusive, and overt coronary artery disease or myocardial infarction is often the first clinical manifestation. Nanoparticles represent a novel strategy for prevention, diagnosis, and treatment of atherosclerosis, and new multifunctional nanoparticles with combined diagnostic and therapeutic capacities hold the promise for theranostic approaches to this disease. This review focuses on the development of nanosystems for therapy and diagnosis of subclinical atherosclerosis, coronary artery disease, and myocardial infarction and the evolution of nanosystems as theranostic tools. We also discuss the use of nanoparticles in noninvasive imaging, targeted drug delivery, photothermal therapies together with the challenges faced by nanosystems during clinical translation. PMID- 30279734 TI - Mesenchymal glioblastoma constitutes a major ceRNA signature in the TGF-beta pathway. AB - Rationale: Competitive endogenous RNA (ceRNA) networks play important roles in posttranscriptional regulation. Their dysregulation is common in cancer. However, ceRNA signatures have been poorly examined in the invasive and aggressive phenotypes of mesenchymal glioblastoma (GBM). This study aims to characterize mesenchymal glioblastoma at the mRNA-miRNA level and identify the mRNAs in ceRNA networks (micNET) markers and their mechanisms in tumorigenesis. Methods: The mRNAs in ceRNA networks (micNETs) of glioblastoma were investigated by constructing a GBM ceRNA network followed by integration with a STRING protein interaction network. The prognostic micNET markers of mesenchymal GBM were identified and validated across multiple datasets. ceRNA interactions were identified between micNETs and miR181 family members. LY2109761, an inhibitor of TGFBR2, demonstrated tumor-suppressive effects on both primary cultured cells and a patient-derived xenograft intracranial model. Results: We characterized mesenchymal glioblastoma at the mRNA-miRNA level and reported a ceRNA network that could separate the mesenchymal subtype from other subtypes. Six genes (TGFBR2, RUNX1, PPARG, ACSL1, GIT2 and RAP1B) that interacted with each other in both a ceRNA-related manner and in terms of their protein functions were identified as markers of the mesenchymal subtype. The coding sequence (CDS) and 3'-untranslated region (UTR) of TGFBR2 upregulated the expression of these genes, whereas TGFBR2 inhibition by siRNA or miR-181a/d suppressed their expression levels. Furthermore, mesenchymal subtype-related genes and the invasion phenotype could be reversed by suppressing the six mesenchymal marker genes. Conclusions: This study suggests that the micNETs may have translational significance in the diagnosis of mesenchymal GBM and may be novel therapeutic targets. PMID- 30279735 TI - Optogenetic sensors in the zebrafish heart: a novel in vivo electrophysiological tool to study cardiac arrhythmogenesis. AB - Cardiac arrhythmias are among the most challenging human disorders to diagnose and treat due to their complex underlying pathophysiology. Suitable experimental animal models are needed to study the mechanisms causative for cardiac arrhythmogenesis. To enable in vivo analysis of cardiac cellular electrophysiology with a high spatial and temporal resolution, we generated and carefully validated two zebrafish models, one expressing an optogenetic voltage indicator (chimeric VSFP-butterfly CY) and the other a genetically encoded calcium indicator (GCaMP6f) in the heart. Methods: High-speed epifluorescence microscopy was used to image chimeric VSFP-butterfly CY and GCaMP6f in the embryonic zebrafish heart, providing information about the spatiotemporal patterning of electrical activation, action potential configuration and intracellular Ca2+ dynamics. Plotting VSFP or GCaMP6f signals on a line along the myocardial wall over time facilitated the visualization and analysis of electrical impulse propagation throughout the heart. Administration of drugs targeting the sympathetic nervous system or cardiac ion channels was used to validate sensitivity and kinetics of both zebrafish sensor lines. Using the same microscope setup, we imaged transparent juvenile casper fish expressing GCaMP6f, demonstrating the feasibility of imaging cardiac optogenetic sensors at later stages of development. Results: Isoproterenol slightly increased heart rate, diastolic Ca2+ levels and Ca2+ transient amplitudes, whereas propranolol caused a profound decrease in heart rate and Ca2+ transient parameters in VSFP-Butterfly and GCaMP6f embryonic fish. Ikr blocker E-4031 decreased heart rate and increased action potential duration in VSFP-Butterfly fish. ICa,L blocker nifedipine caused total blockade of Ca2+ transients in GCaMP6f fish and a reduced heart rate, altered ventricular action potential duration and disrupted atrial-ventricular electrical conduction in VSFP-Butterfly fish. Imaging of juvenile animals demonstrated the possibility of employing an older zebrafish model for in vivo cardiac electrophysiology studies. We observed differences in atrial and ventricular Ca2+ recovery dynamics between 3 dpf and 14 dpf casper fish, but not in Ca2+ upstroke dynamics. Conclusion: By introducing the optogenetic sensors chimeric VSFP-butterfly CY and GCaMP6f into the zebrafish we successfully generated an in vivo cellular electrophysiological readout tool for the zebrafish heart. Complementary use of both sensor lines demonstrated the ability to study heart rate, cardiac action potential configuration, spatiotemporal patterning of electrical activation and intracellular Ca2+ homeostasis in embryonic zebrafish. In addition, we demonstrated the first successful use of an optogenetic sensor to study cardiac function in older zebrafish. These models present a promising new research tool to study the underlying mechanisms of cardiac arrhythmogenesis. PMID- 30279736 TI - Simultaneous characterization of tumor cellularity and the Warburg effect with PET, MRI and hyperpolarized 13C-MRSI. AB - Modern oncology aims at patient-specific therapy approaches, which triggered the development of biomedical imaging techniques to synergistically address tumor biology at the cellular and molecular level. PET/MR is a new hybrid modality that allows acquisition of high-resolution anatomic images and quantification of functional and metabolic information at the same time. Key steps of the Warburg effect-one of the hallmarks of tumors-can be measured non-invasively with this emerging technique. The aim of this study was to quantify and compare simultaneously imaged augmented glucose uptake and LDH activity in a subcutaneous breast cancer model in rats (MAT-B-III) and to study the effect of varying tumor cellularity on image-derived metabolic information. Methods: For this purpose, we established and validated a multimodal imaging workflow for a clinical PET/MR system including proton magnetic resonance (MR) imaging to acquire accurate morphologic information and diffusion-weighted imaging (DWI) to address tumor cellularity. Metabolic data were measured with dynamic [18F]FDG-PET and hyperpolarized (HP) 13C-pyruvate MR spectroscopic imaging (MRSI). We applied our workflow in a longitudinal study and analyzed the effect of growth dependent variations of cellular density on glycolytic parameters. Results: Tumors of similar cellularity with similar apparent diffusion coefficients (ADC) showed a significant positive correlation of FDG uptake and pyruvate-to-lactate exchange. Longitudinal DWI data indicated a decreasing tumor cellularity with tumor growth, while ADCs exhibited a significant inverse correlation with PET standard uptake values (SUV). Similar but not significant trends were observed with HP-13C-MRSI, but we found that partial volume effects and point spread function artifacts are major confounders for the quantification of 13C-data when the spatial resolution is limited and major blood vessels are close to the tumor. Nevertheless, analysis of longitudinal data with varying tumor cellularity further detected a positive correlation between quantitative PET and 13C-data. Conclusions: Our workflow allows the quantification of simultaneously acquired PET, MRSI and DWI data in rodents on a clinical PET/MR scanner. The correlations and findings suggest that a major portion of consumed glucose is metabolized by aerobic glycolysis in the investigated tumor model. Furthermore, we conclude that variations in cell density affect PET and 13C-data in a similar manner and correlations of longitudinal metabolic data appear to reflect both biochemical processes and tumor cellularity. PMID- 30279737 TI - RGS4 deficit in prefrontal cortex contributes to the behaviors related to schizophrenia via system xc --mediated glutamatergic dysfunction in mice. AB - Rationale: Although molecular investigations of regulator of G-protein signaling 4 (RGS4) alterations in schizophrenia patients yielded partially inconsistent findings, the previous studies suggested that RGS4 is both a positional and functional candidate gene for schizophrenia and is significantly decreased in the prefrontal cortex. However, the exact role of RGS4 in the pathophysiology of schizophrenia is unclear. Moreover, a whole genome transcription profile study showed the possibility of RGS4-regulated expression of SLC7A11(xCT), a component of cysteine/glutamate transporter or system xc -. We hypothesized that system xc is a therapeutic target of RGS4 deficit-mediated schizophrenia. Methods: Pharmacological and genetic manipulation of RGS4 in organotypic brain slice cultures were used as an ex vivo model to investigate its role in system xc - and glutamatergic function. Lentiviral-based mouse models with RGS4 deficit in the prefrontal cortex and treatment with system xc - activator, N-acetyl cysteine (NAC), were utilized to observe their impacts on glutamatergic function and schizophrenic behaviors. Results: Genetic and pharmacological inhibition of RGS4 resulted in a significant decrease in SLC7A11 (xCT) expression and hypofunction of system xc - and reduced glutamatergic function in organotypic brain slice cultures. However, NAC restored the dysregulation of RGS4-mediated functional deficits of glutamate. Moreover, knockdown of RGS4 specifically in the prefrontal cortex caused mice to exhibit behaviors related to schizophrenia such as increased stereotypy, impaired prepulse inhibition, deficits in social interactions, working memory, and nesting behavior, while enhancing sensitivity to the locomotor stimulatory effect of MK-801. These mice displayed glutamatergic dysfunction in the prefrontal cortex, which may have contributed to the behavioral deficits. RGS4 knockdown mice that received NAC treatment had improved glutamatergic dysfunction and schizophrenia behaviors. Conclusion: Our results suggest that RGS4 deficit induces dysregulation and dysfunction of system xc -, which further results in functional deficits of the glutamatergic system and subsequently to schizophrenia-related behavioral phenotypes. Activation of system xc - offers a promising strategy to treat RGS4 deficit-mediated schizophrenia. PMID- 30279738 TI - Inhibition of Notch1 induces population and suppressive activity of regulatory T cell in inflammatory arthritis. AB - Inhibition of Notch signalling has shown anti-inflammatory properties in vivo and in vitro models of rheumatoid arthritis (RA). The objective of this study was to determine whether Notch1 might play a role in regulating T-regulatory cells (Tregs) in animal models of RA. Methods: Collagen-induced arthritis (CIA) and collagen antibody-induced arthritis (CAIA) were induced in C57BL/6, Notch1 antisense transgenic (NAS) or DBA1/J mice. We examined whether pharmacological inhibitors of gamma-secretase (an enzyme required for Notch1 activation) and antisense-mediated knockdown of Notch1 could attenuate the severity of inflammatory arthritis in CIA and CAIA mice. Proportions of CD4+CD25+Foxp3+ Treg cells were measured by flow cytometry. To assess the suppressive capacity of Treg toward responder cells, CFSE-based suppression assay of Treg was performed. Results: gamma-secretase inhibitors and antisense-mediated knockdown of Notch1 reduced the severity of inflammatory arthritis in both CIA and CAIA mice. Pharmacological and genetic inhibition of Notch1 signalling induced significant elevation of Treg cell population in CIA and CAIA mice. We also demonstrated that inhibition of Notch signalling suppressed the progression of inflammatory arthritis through modulating the expansion and suppressive function of regulatory T (Treg) cells. Conclusion: Pharmacological and genetic inhibition of Notch1 signalling suppresses the progression of inflammatory arthritis through modulating the population and suppressive function of Treg cells in animal models of RA. PMID- 30279739 TI - WNT6 is a novel oncogenic prognostic biomarker in human glioblastoma. AB - Glioblastoma (GBM) is a universally fatal brain cancer, for which novel therapies targeting specific underlying oncogenic events are urgently needed. While the WNT pathway has been shown to be frequently activated in GBM, constituting a potential therapeutic target, the relevance of WNT6, an activator of this pathway, remains unknown. Methods: WNT6 protein and mRNA levels were evaluated in GBM. WNT6 levels were silenced or overexpressed in GBM cells to assess functional effects in vitro and in vivo. Phospho-kinase arrays and TCF/LEF reporter assays were used to identify WNT6-signaling pathways, and significant associations with stem cell features and cancer-related pathways were validated in patients. Survival analyses were performed with Cox regression and Log-rank tests. Meta analyses were used to calculate the estimated pooled effect. Results: We show that WNT6 is significantly overexpressed in GBMs, as compared to lower-grade gliomas and normal brain, at mRNA and protein levels. Functionally, WNT6 increases typical oncogenic activities in GBM cells, including viability, proliferation, glioma stem cell capacity, invasion, migration, and resistance to temozolomide chemotherapy. Concordantly, in in vivo orthotopic GBM mice models, using both overexpressing and silencing models, WNT6 expression was associated with shorter overall survival, and increased features of tumor aggressiveness. Mechanistically, WNT6 contributes to activate typical oncogenic pathways, including Src and STAT, which intertwined with the WNT pathway may be critical effectors of WNT6-associated aggressiveness in GBM. Clinically, we establish WNT6 as an independent prognostic biomarker of shorter survival in GBM patients from several independent cohorts. Conclusion: Our findings establish WNT6 as a novel oncogene in GBM, opening opportunities to develop more rational therapies to treat this highly aggressive tumor. PMID- 30279740 TI - Neurogliovascular dysfunction in a model of repeated traumatic brain injury. AB - Traumatic brain injury (TBI) research has focused on moderate to severe injuries as their outcomes are significantly worse than those of a mild TBI (mTBI). However, recent epidemiological evidence has indicated that a series of even mild TBIs greatly increases the risk of neurodegenerative and psychiatric disorders. Neuropathological studies of repeated TBI have identified changes in neuronal ionic concentrations, axonal injury, and cytoskeletal damage as important determinants of later life neurological and mood compromise; yet, there is a paucity of data on the contribution of neurogliovascular dysfunction to the progression of repeated TBI and alterations of brain function in the intervening period. Methods: Here, we established a mouse model of repeated TBI induced via three electromagnetically actuated impacts delivered to the intact skull at three day intervals and determined the long-term deficits in neurogliovascular functioning in Thy1-ChR2 mice. Two weeks post the third impact, cerebral blood flow and cerebrovascular reactivity were measured with arterial spin labelling magnetic resonance imaging. Neuronal function was investigated through bilateral intracranial electrophysiological responses to optogenetic photostimulation. Vascular density of the site of impacts was measured with in vivo two photon fluorescence microscopy. Pathological analysis of neuronal survival and astrogliosis was performed via NeuN and GFAP immunofluorescence. Results: Cerebral blood flow and cerebrovascular reactivity were decreased by 50+/-16% and 70+/-20%, respectively, in the TBI cohort relative to sham-treated animals. Concomitantly, electrophysiological recordings revealed a 97+/-1% attenuation in peri-contusional neuronal reactivity relative to sham. Peri-contusional vascular volume was increased by 33+/-2% relative to sham-treated mice. Pathological analysis of the peri-contusional cortex demonstrated astrogliosis, but no changes in neuronal survival. Conclusion: This work provides the first in-situ characterization of the long-term deficits of the neurogliovascular unit following repeated TBI. The findings will help guide the development of diagnostic markers as well as therapeutics targeting neurogliovascular dysfunction. PMID- 30279742 TI - Evaluation of antibody fragment properties for near-infrared fluorescence imaging of HER3-positive cancer xenografts. AB - In vivo imaging is influenced by the half-life, tissue penetration, biodistribution, and affinity of the imaging probe. Immunoglobulin G (IgG) is composed of discrete domains with known functions, providing a template for engineering antibody fragments with desired imaging properties. Here, we engineered antibody-based imaging probes, consisting of different combinations of antibody domains, labeled them with the near-infrared fluorescent dye IRDye800CW, and evaluated their in vivo imaging properties. Antibody-based imaging probes were based on an anti-HER3 antigen binding fragment (Fab) isolated using phage display. Methods: We constructed six anti-HER3 antibody-based imaging probes: a single chain variable fragment (scFv), Fab, diabody, scFv-CH3, scFv-Fc, and IgG. IRDye800CW-labeled, antibody-based probes were injected into nude mice bearing FaDu xenografts and their distribution to the xenograft, liver, and kidneys was evaluated. Results: These imaging probes bound to recombinant HER3 and to the HER3-positive cell line, FaDu. Small antibody fragments with molecular weight <60 kDa (scFv, diabody, and Fab) accumulated rapidly in the xenograft (maximum accumulation between 2-4 h post injection (hpi)) and cleared primarily through the kidneys. scFv-CH3 (80 kDa) had fast clearance and peaked in the xenograft between 2-3 hpi and cleared from xenograft in a rate comparable to Fab and diabody. IgG and scFv-Fc persisted in the xenografts for up to 72 hpi and distributed mainly to the xenograft and liver. The highest xenograft fluorescence signals were observed with IgG and scFv-Fc imaging probes and persisted for 2-3 days. Conclusion: These results highlight the utility of using antibody fragments to optimize clearance, tumor labeling, and biodistribution properties for developing anti-HER3 probes for image-guided surgery or PET imaging. PMID- 30279741 TI - MRI and histological evaluation of pulsed focused ultrasound and microbubbles treatment effects in the brain. AB - Magnetic resonance imaging (MRI)-guided pulsed focused ultrasound (pFUS) combined with microbubbles (MB) contrast agent infusion has been shown to transiently disrupt the blood-brain barrier (BBBD), increasing the delivery of neurotherapeutics to treat central nervous system (CNS) diseases. pFUS interaction with the intravascular MB results in acoustic cavitation forces passing through the neurovascular unit (NVU), inducing BBBD detected on contrast enhanced MRI. Multiple pFUS+MB exposures in Alzheimer's disease (AD) models are being investigated as a method to clear amyloid plaques by activated microglia or infiltrating immune cells. Since it has been reported that pFUS+MB can induce a sterile inflammatory response (SIR) [1-5] in the rat, the goal of this study was to investigate the potential long-term effects of SIR in the brain following single and six weekly sonications by serial high-resolution MRI and pathology. Methods: Female Sprague Dawley rats weighing 217+/-16.6 g prior to sonication received bromo-deoxyuridine (BrdU) to tag proliferating cells in the brain. pFUS was performed at 548 kHz, ultrasound burst 10 ms and initial peak negative pressure of 0.3 MPa (in water) for 120 s coupled with a slow infusion of ~460 uL/kg (5-8*107 MB) that started 30 s before and 30 s during sonication. Nine 2 mm focal regions in the left cortex and four regions over the right hippocampus were treated with pFUS+MB. Serial high-resolution brain MRIs at 3 T and 9.4 T were obtained following a single or during the course of six weekly pFUS+MB resulting in BBBD in the left cortex and the right hippocampus. Animals were monitored over 7 to 13 weeks and imaging results were compared to histology. Results: Fewer than half of the rats receiving a single pFUS+MB exposure displayed hypointense voxels on T2*-weighted (w) MRI at week 7 or 13 in the cortex or hippocampus without differences compared to the contralateral side on histograms of T2* maps. Single sonicated rats had evidence of limited microglia activation on pathology compared to the contralateral hemisphere. Six weekly pFUS+MB treatments resulted in pathological changes on T2*w images with multiple hypointense regions, cortical atrophy, along with 50% of rats having persistent BBBD and astrogliosis by MRI. Pathologic analysis of the multiple sonicated animals demonstrated the presence of metallophagocytic Prussian blue-positive cells in the parenchyma with significantly (p<0.05) increased areas of activated astrocytes and microglia, and high numbers of systemic infiltrating CD68+ macrophages along with BrdU+ cells compared to contralateral brain. In addition, multiple treatments caused an increase in the number of hyperphosphorylated Tau (pTau)-positive neurons containing neurofibrillary tangles (NFT) in the sonicated cortex but not in the hippocampus when compared to contralateral brain, which was confirmed by Western blot (WB) (p<0.04). Conclusions: The repeated SIR following multiple pFUS+MB treatments could contribute to changes on MR imaging including persistent BBBD, cortical atrophy, and hypointense voxels on T2w and T2*w images consistent with pathological injury. Moreover, areas of astrogliosis, activated microglia, along with higher numbers of CD68+ infiltrating macrophages and BrdU+ cells were detected in multiple sonicated areas of the cortex and hippocampus. Elevations in pTau and NFT were detected in neurons of the multiple sonicated cortex. Minimal changes on MRI and histology were observed in single pFUS+MB-treated rats at 7 and 13 weeks post sonication. In comparison, animals that received 6 weekly sonications demonstrated evidence on MRI and histology of vascular damage, inflammation and neurodegeneration associated with the NVU commonly observed in trauma. Further investigation is recommended of the long-term effects of multiple pFUS+MB in clinical trials. PMID- 30279744 TI - A case of reverse takotsubo cardiomyopathy caused by an eating disorder. AB - Takotsubo cardiomyopathy is an acquired transient cardiomyopathy that causes severe systolic dysfunction in the absence of coronary disease. Here we present a case of reverse takotsubo cardiomyopathy. A 67-year-old female was admitted for weakness and falls due to severe malnutrition. During her stay she was diagnosed with an eating disorder. She also developed chest pain during her hospitalization and was taken urgently for catheterization which showed normal coronary arteries with akinetic basal and inferior walls and hyperkinesis of the apex. Her ejection fraction decreased to 25% from 60% five days previously. She was diagnosed with reverse takotsubo. She was placed on an appropriate heart failure regimen and eventually transferred to inpatient rehabilitation. In its typical form, takotsubo causes apical ballooning due to hyperkinetic basal and inferior wall motion and apical hypokinesis. Reverse takotsubo causes a depressed basal segment with apical hyperkinesis usually brought on by severe emotional or physical stress. Our case is the first documented report of an eating disorder causing the reverse type of takotsubo cardiomyopathy. . PMID- 30279745 TI - Interesting electrophysiological findings in a patient with coexistence of atrial tachycardia originating from coronary sinus and slow-fast atrioventricular nodal reentrant tachycardia. AB - Slow-fast atrioventricular nodal tachycardia (AVNRT) has various electrophysiological aspects due to atrioventricular (AV) nodal physiology. In addition, concomitantly another form of arrhythmia with AVNRT, especially atrial tachycardia (AT), was an infrequent arrhythmia. A 38-year-old female with narrow QRS tachycardia underwent electrophysiological study due to frequent faintness. The electrophysiological study disclosed the coexistence of AT originating from coronary sinus (CS) with slow-fast AVNRT. We easily diagnosed AT originating from CS and terminated with several radiofrequency ablations (RFA) around CS. The diagnosis of slow-fast AVNRT, however, was somewhat difficult due to the following findings: (1) small amount of adenosine triphosphate (ATP) could terminate slow-fast AVNRT reproducibly; (2) we could provoke slow-fast AVNRT only by RV pacing with isoproterenol infusion. With other electrophysiological findings, we diagnosed slow-fast AVNRT. Radiofrequency energy was delivered initially in the posteroseptal region, followed by inside CS, and finally in the middle septal region, which completed the slow pathway ablation. After the procedure, we could never provoke these arrhythmias. . PMID- 30279746 TI - Simultaneous occurrence of spontaneous coronary artery dissections of the left anterior descending and right coronary arteries in acute myocardial infarction. AB - Spontaneous coronary artery dissection (SCAD) is a rare and often fatal cause of ischemic heart disease that occurs predominantly in young or middle-aged patients who are otherwise healthy. Therefore, the accurate diagnosis of SCAD and initiation of appropriate treatment may be life-saving. Although recent case reports have described patients with SCAD who exhibited multiple coronary dissections in addition to the culprit lesion, the authors could not determine whether the multiple dissections occurred simultaneously or at different times. In this report, we describe a case involving the simultaneous occurrence of multiple SCADs in the right coronary artery and left anterior descending artery. Intravascular ultrasound helped us to confirm the diagnosis of multiple SCADs, confirm their simultaneous occurrence, and navigate the guidewire into the true lumen. . PMID- 30279747 TI - Unilateral recurrent nerve palsy and cardiovascular disease - Ortner's syndrome. AB - Recurrent laryngeal palsies are relatively common. Frequently, surgical procedures precede paresis. In rare cases a compression of the recurrent laryngeal nerve can be caused by enlarged cardiovascular structures. The phenomenon of compression of the left recurrent laryngeal nerve is explicitly designated as Ortner's syndrome, first described in 1897 by Norbert Ortner. Nowadays the compression of the right recurrent laryngeal nerve by cardiovascular structures is also associated with Ortner's syndrome. We report two cases of an 82- and a 71-year-old patient who presented with hoarseness and each right- and left-sided vocal cord paralysis for further diagnosis. The ear, nose, and throat (ENT) examinations revealed no clarifying findings besides the vocal cord palsy, so extensive imaging techniques were used. The cause of left-sided recurrent laryngeal nerve palsy was a penetrated aortic ulcer caused by large thrombosed aneurysm of the aortic arch. The right-sided paresis arose due to aneurysmal enlargement of the brachiocephalic trunk and an aneurysm of right subclavian artery. These cases demonstrate that interdisciplinary medical work is important. The internal medical presentation of a patient with hoarseness without ENT medical findings should be considered. . PMID- 30279749 TI - Unmasking the culprit: MAPCA masquerading as RV failure in post surgical correction of TOF. AB - Pulmonary regurgitation and right ventricular dilatation are major determinants of long-term follow up of surgically corrected tetralogy of Fallot. Occasionally, there are undiagnosed associated anomalies, which can exaggerate pulmonary regurgitation. The present report describes long-term effect of major aorto pulmonary collateral on right ventricular volume also a result of successful intervention. . PMID- 30279743 TI - Biomarker of food intake for assessing the consumption of dairy and egg products. AB - Dairy and egg products constitute an important part of Western diets as they represent an excellent source of high-quality proteins, vitamins, minerals and fats. Dairy and egg products are highly diverse and their associations with a range of nutritional and health outcomes are therefore heterogeneous. Such associations are also often weak or debated due to the difficulty in establishing correct assessments of dietary intake. Therefore, in order to better characterize associations between the consumption of these foods and health outcomes, it is important to identify reliable biomarkers of their intake. Biomarkers of food intake (BFIs) provide an accurate measure of intake, which is independent of the memory and sincerity of the subjects as well as of their knowledge about the consumed foods. We have, therefore, conducted a systematic search of the scientific literature to evaluate the current status of potential BFIs for dairy products and BFIs for egg products commonly consumed in Europe. Strikingly, only a limited number of compounds have been reported as markers for the intake of these products and none of them have been sufficiently validated. A series of challenges hinders the identification and validation of BFI for dairy and egg products, in particular, the heterogeneous composition of these foods and the lack of specificity of the markers identified so far. Further studies are, therefore, necessary to validate these compounds and to discover new candidate BFIs. Untargeted metabolomic strategies may allow the identification of novel biomarkers, which, when taken separately or in combination, could be used to assess the intake of dairy and egg products. PMID- 30279748 TI - A case of biventricular thrombi in a patient with dilated cardiomyopathy: Utility of multimodality imaging for diagnosis and management of treatment strategy. AB - A 54-year-old man was transferred to our hospital due to congestive heart failure and left ventricular thrombi. Transthoracic echocardiography (TTE) showed mobile "ball-like" not only left ventricular but also right ventricular thrombi associated with severe impaired left and right ventricular function. Contrast enhanced computed tomography (CT) and cardiac magnetic resonance imaging (MRI) also detected biventricular apical thrombi complicated with right renal infarction. Coronary angiography showed non-significant stenosis. Due to the mobility of thrombi and complication of systemic infarction, the surgical transatrial video-assisted removal of biventricular thrombi was performed and postoperative course has been uneventful over a period of 6 months. Endomyocardial biopsy performed during an operation showed no specific findings such as endomyocarditis, indicating the diagnosis of dilated cardiomyopathy (DCM). This is a rare case of DCM complicated with biventricular apical thrombi detected clearly by multimodality imaging such as TTE, contrast-enhanced CT and cardiac MRI, and surgical removal was performed successfully. . PMID- 30279750 TI - Left circumflex coronary artery to coronary sinus fistula diagnosed in infancy. AB - Coronary artery fistulas are rare anomalies, their incidence range from 0.1 to 0.2% of congenital heart defects. The left circumflex coronary artery (LCX) fistula draining into the coronary sinus (CS) is a less common form, and most cases described in the literature were adult cases. We are describing this type of fistula in an 8-month-old asymptomatic female presenting with a continuous murmur over the pericordium. Electrocardiogram was normal. Echocardiography revealed a dilated LCX and CS with turbulent flow in CS; 2-D speckle tracking echocardiography revealed normal left ventricular strain with no regional wall abnormalities. Multidetector computed tomography demonstrated the fistula. As the patient was asymptomatic, with no ventricular dilatation or dysfunction, we decided conservatively. . PMID- 30279751 TI - A case of fatal heart and liver failure accompanied by thyroid storm treated with prompt plasma exchange. AB - A 36-year-old man with a history of Graves' disease was admitted complaining of dyspnea. He was diagnosed with acute heart failure and severe liver dysfunction accompanied by thyroid storm. Left ventricular ejection fraction was 19%, and liver enzyme levels were markedly elevated followed with coagulation disorders. In addition to the conventional therapy, we performed plasma exchange emergently. Thyroid hormone levels promptly normalized, then his clinical condition improved. Finally, his cardiac and liver function almost normalized from a fatal condition without serious complications. Hyperthyroidism can cause myocardial and liver injury, hence thyroid hormone removal in acute phase is important. Prompt plasma exchange is effective in the acute phase for heart and liver failure accompanied by thyroid storm. . PMID- 30279752 TI - Penetration of inferior vena cava filter strut through an introducer sheath inserted from the left internal jugular vein: An anatomical pitfall. AB - The report describes a case of penetration of an inferior vena cava filter (IVCF) strut through an introducer sheath inserted from the left internal jugular vein. A 64-year-old woman was admitted to our hospital with pulmonary embolism and lower extremity deep vein thrombosis. We attempted to implant a retrievable type IVCF via the left internal jugular vein. However, an unexpected resistance occurred during the advancement of the filter after passing the first few inches within the 8-Fr introducer sheath. Immediately, we checked the insertion site using fluoroscopy, which demonstrated penetration of the filter struts to the outside of the sheath. We speculate that a strong angulation in the vessel from the left internal jugular to superior vena cava might have contributed to this rare complication. . PMID- 30279753 TI - An infant with truncus arteriosus with situs inversus with single atrium: A case report. AB - Truncus arteriosus is a rare heart defect comprising <1% of congenital cyanotic heart disease. Rarely it may be associated with single ventricle, but association with single atrium is very rare. We report a case of truncus arteriosus (Van Praag type A2) with single atrium and single ventricle. . PMID- 30279754 TI - Right-sided cardiac resynchronization therapy with defibrillator implantation in a patient with corrected transposition of great arteries and persistent left superior vena cava. AB - Patients with corrected transposition of great arteries (c-TGA) are generally known to develop atrioventricular block, systemic right ventricular dysfunction, and tricuspid regurgitation over time, which are associated with tachyarrhythmia and progressive heart failure. A 76-year-old man had been diagnosed with c-TGA. He developed a cardiopulmonary arrest while playing tennis, and an automated external defibrillator detected ventricular fibrillation (VF). Immediate cardiopulmonary resuscitation and intensive treatment were performed. He fully recovered without neurological sequelae. QRS duration was 172 ms. Echocardiography showed marked dysfunction and dyssynchrony of the systemic right ventricle (systemic right ventricular end-diastolic diameter/end-systolic diameter = 73/60 mm, systemic right ventricular ejection fraction = 34%). For secondary prevention and treatment of progressive heart failure, cardiac resynchronization therapy with defibrillator (CRT-D) implantation was recommended. Venography via the left cubital superficial vein revealed a persistent left superior vena cava (PLSVC) and giant coronary sinus that did not connect with the right superior vena cava (SVC). Because of the acute angle between the PLSVC and great cardiac vein, we selected a right-sided approach via the right SVC. We were finally able to deliver a coronary sinus lead to the lateral vein. CRT-D implantation can be achieved even in patients with c-TGA and PLSVC. . PMID- 30279755 TI - Coronary vasospasm complicating cannabinoid hyperemesis syndrome. AB - Cannabinoid hyperemesis syndrome (CHS) is a clinical condition that was first described in 2004. The syndrome may occasionally be observed in long-term cannabis users and is characterized by a set of features: severe cyclic nausea and vomiting, recurrent epigastric or periumbilical pain, relief of symptoms with hot baths, and cannabis use cessation. The pathophysiology is not fully understood but is probably related to Cannabinoid-1 (CB-1) receptors dysregulation. On the other hand, there is also growing epidemiological evidence that cannabis smoking may trigger acute coronary syndrome (ACS) in young men. We describe the case of 41-year-old man with a long history of cannabis smoking who not only complained of recurrent epigastric but also of retrosternal pain. He had undergone several negative radiological or endoscopic investigations. During the last episode, electrocardiographic and echocardiographic changes were consistent with takotsubo cardiomyopathy. However, the patient was readmitted very soon with a ST-elevation myocardial infarction related to coronary vasospasm. While the link between CHS and ACS is not established, CHS patients with atypical pain should be investigated carefully to exclude any serious cardiac event. . PMID- 30279756 TI - Transradial retrograde percutaneous transluminal angioplasty with stenting of long segment occlusion of subclavian artery. AB - We report a case of retrograde percutaneous transluminal angioplasty with stenting to chronically occluded upper limb vessels in a young female with Takayasu arteritis. A self-expanding stent (Supera peripheral stent system - Abbott Vascular, Santa Clara, CA, USA) was tracked retrogradely via ipsilateral radial access and the procedure was successful with good results. To our knowledge this is the first report of a Supera stent being tracked retrogradely through the radial artery. . PMID- 30279758 TI - A case of life-threatening supraventricular tachycardia storm associated with theophylline toxicity. AB - A 76-year-old man taking theophylline was admitted to our hospital with congestive heart failure and supraventricular tachycardia (SVT). After admission, he developed cardiogenic shock as a result of SVT storm, which was refractory to medical treatment including adenosine and electrical cardioversion. The serum theophylline concentration at admission was identified as toxic. Therefore, theophylline toxicity was considered as a major cause of the SVT storm. Hemodynamic stability was achieved by using mechanical circulatory support. Additionally, continuous hemodiafiltration was performed to remove theophylline, and it was effective for suppression of SVT. The patient was successfully weaned off mechanical circulatory support. After the patient's general status had improved, an electrophysiological study was performed, and it showed orthodromic atrioventricular reentrant tachycardia with a right free wall accessory pathway. Radiofrequency catheter ablation was successfully performed. . PMID- 30279757 TI - Comprehensive arrhythmic surgery for sustained ventricular tachycardia revisited. AB - A 68-year-old woman with a history of old inferior myocardial infarction was admitted because of sustained ventricular tachycardia. Double vessel coronary disease was found with subtotal obstruction of the right coronary artery (#1) and severe stenosis of the left circumflex coronary artery (#13). Dilated left ventricle with a large ventricular aneurysm at the inferior wall and severely reduced systolic function were also present. A comprehensive surgical ablation using subendocardial resection and cryoablation was performed in combination with aneurysmectomy, left ventricular reconstruction, and coronary bypass grafting to the circumflex coronary artery. An implantable cardioverter-defibrillator was also implanted. She has remained well without recurrence of sustained ventricular tachycardia for one year. Although radiofrequency catheter ablation is nowadays considered a first-line therapy for patients with sustained ventricular tachycardia, surgical ablation remains a valuable option for selected patients, particularly for those requiring left ventricular aneurysmectomy and coronary artery bypass grafting, in order to gain a better long-term prognosis through total cure of ventricular tachycardia. . PMID- 30279759 TI - Giant left atrial appendage aneurysm: A case of mistaken identity. AB - Left atrial appendage (LAA) aneurysm is a rare condition that can be congenital or acquired. Most cases are discovered incidentally. However, the most frequent clinical presentations include supraventricular tachycardias and systemic embolization. Most cases in the literature were treated by resection of the LAA, and it has been recommended to perform LAA resection even in asymptomatic patients in order to prevent thromboembolic events. Here, we describe the safe, conservative management of a patient who was initially felt to have congenital partial absence of the left pericardium but at surgery the diagnosis of LAA aneurysm was established. . PMID- 30279760 TI - Silent cardiac tumor with neurological manifestations. AB - Atrial myxoma is rare and can be completely asymptomatic. However, an untreated myxoma may result in catastrophic events. Diagnosis is usually suggested by echocardiography, and other imaging modalities can add important information. Myxoma can be cured surgically, and histological analysis usually gives the definite diagnosis. This article describes the case of a 61-year-old woman whose clinical presentation of an atrial myxoma was a stroke. Echocardiographic findings were highly suggestive of a cardiac myxoma. However, cardiac magnetic resonance showed unusual features for myxoma, since the mass was hyperintense in T1-weighted images and hypointense in T2-weighted sequences. Histology confirmed myxoma and the patient was surgically treated. This case enhances the importance of multimodality imaging in the differential diagnosis of cardiac masses. . PMID- 30279762 TI - Kounis syndrome type I in a victim of cardiopulmonary arrest after hymenoptera sting. AB - Kounis syndrome is a relatively rare entity in which allergic or hypersensitivity reactions (including anaphylaxis) coexist with acute coronary syndromes. We report a case of Kounis syndrome type I variant in a 51-year-old male, victim of an out-of-hospital cardiac arrest a few minutes after a hymenoptera sting. Iotan hospital cardiopulmonary resuscitation was provided and return of spontaneous circulation was achieved. The post-resuscitation electrocardiogram revealed ST segment elevation in leads II, III, aVF, and ST depression in leads V2, V3, and V4. After administration of corticosteroids, antihistamines, nitrates, and a calcium-channel blocker the electrocardiogram rapidly returned to normal. There was no elevation in markers of myocardial necrosis and the coronary angiography revealed normal coronary arteries. According to the clinical course and the laboratory findings the diagnosis of Kounis syndrome type I variant was made. Only a few cases of Kounis syndrome in the setting of cardiopulmonary arrest have been published. We believe that in these cases, the recognition of the main underlying cause that lead to arrest (acute coronary syndrome or severe anaphylactic reaction) plays an important role in the choice of the most appropriate treatment for the patient. . PMID- 30279761 TI - Role of 99mTc-sestamibi gated SPECT/CT myocardial perfusion imaging in the management of patients with myocardial bridging and its correlation with coronary angiography. AB - Myocardial bridging (MB)-a congenital coronary abnormality in its severe form leads to myocardial edema, fibrosis, and ischemia due to coronary artery compression during systole and early part of the diastole. This study evaluated the hemodynamic significance of MB by detecting severity and extent of perfusion abnormality using 99mTc-sestamibi (MIBI) gated single photon emission computed tomography (SPECT)/CT myocardial perfusion imaging (MPI), its correlation with coronary angiography and role in patient's management. Five patients with complaints of atypical chest pain, exertional angina, or dyspnea underwent stress/rest 99mTc-MIBI SPECT/CT MPI. The gated stress and rest SPECT/CT images on 17 segment model using quantitative gated-SPECT (QGS) softwarewere analyzed and compared with coronary angiography. Four out of five patients showed reversible perfusion defect in the left anterior descending (LAD) territory segments involved with myocardial bridging (3 patients had already proven MB; while MB was detected in 1 patient after MPI). The fifth patient with MB in the distal LAD revealed normal myocardial perfusion. All the patients were conservatively managed either due to small reversible perfusion defects or normal study except one patient. The gated SPECT/CT MPI of five patients with MB in the present study revealed their perfusion status, information on myocardial wall thickening, contractility, and ejection fraction. . PMID- 30279763 TI - A case of heparin-induced thrombocytopenia with subacute stent thrombosis, multiple cerebral infarction, and acute limb ischemia. AB - Heparin-induced thrombocytopenia (HIT) is an adverse immune-mediated drug reaction that is associated with thromboembolic complications. We report the case of an 82-year-old man with unstable angina pectoris who suffered from recurrent arterial thromboembolism due to HIT. Coronary angiography (CAG) was performed while we administered unfractionated heparin bolus. CAG showed triple-vessel disease without left main coronary artery. We performed elective percutaneous coronary angioplasty (PCI) to the left anterior descending coronary artery (LAD). The sudden thrombus formation in the LAD occurred during the procedure. We suspected HIT and administered argatroban. We deployed four everolimus-eluting stents in the LAD and intra-aortic balloon pumping (IABP) support was started. The platelet counts were rapidly reduced almost 50% next day after PCI and IgG specific anti-PF4/heparin antibodies were elevated. Multiple cerebral infarctions were detected by magnetic resonance imaging after the PCI. The patient received the continuous argatroban administration and IABP support for 4 days. Subacute stent thrombosis occurred after quitting argatroban. We performed thrombus aspiration and fibrinolytic treatment. Finally we re-inserted IABP and stabilized the hemodynamic state. Right popliteal arterial thromboembolism occurred after emergency PCI. Argatroban is essential and following oral anticoagulant therapy is necessary to prevent thromboembolic complications. . PMID- 30279764 TI - Ascending aortic dissection in a young patient using a synephrine-containing workout supplement. AB - Aortic dissection in young patients presents a clinical and diagnostic challenge. Atypical symptoms of ascending aortic dissection can delay presentation and diagnosis. Here, we describe a patient with delayed diagnosis of an atypical presentation of ascending aortic dissection after using a synephrine-containing pre-workout supplement. The diagnosis was initially missed on computed tomography, but subsequently made on echocardiography. This is the first reported case of ascending aortic dissection in the setting of synephrine supplementation. This case illustrates a potential cardiovascular adverse effect of synephrine and highlights the need for clinical trials without conflicts of interest assessing its safety. . PMID- 30279765 TI - An unusual cause of cardiogenic shock: Left atrial compression by a spontaneous rupture of an aneurysm of the descending thoracic aorta. AB - A 77-year-old woman presented with a feverish hemodynamic collapse, acute respiratory distress, and dorsal pain, initially treated as a septic shock. Transthoracic echocardiogram revealed an impressive compression of the left atrial cavity, by an extrinsic mass preventing the left ventricle from refilling. Thoracic computed tomography revealed a large hemomediastinum emerging from an aneurysm of the descending thoracic aorta compressing the left atrium. The patient died in refractory cardiogenic collapse. . PMID- 30279766 TI - Familial Carney complex with biatrial cardiac myxoma. AB - We report a case of Carney complex (CNC) with biatrial cardiac myxoma. The patient had left and right atrial myxomas which were resected in a surgery. She showed bilateral adrenal tumors and multiple mammary tumors. She had pigmentation on her lower lip. Previously, her daughter was also diagnosed with CNC with cardiac myxoma. Both of them showed mutations in the PRKAR1A gene. . PMID- 30279767 TI - Simultaneous transcatheter aortic valve implantation and off-pump coronary artery bypass grafting for Takayasu arteritis. AB - We report a patient who underwent simultaneous transcatheter aortic valve implantation and off-pump coronary artery bypass grafting for Takayasu arteritis with diffuse porcelain aorta. The patient was a 59-year-old female with severe aortic stenosis and regurgitation, as well as both coronary ostial stenosis and porcelain aorta. Bilateral internal thoracic arteries were unavailable due to Takayasu arteritis. Therefore, composite radial artery with in-situ gastroepiploic artery was used as graft material. Radial artery was anastomosed to left anterior descending artery and posterior descending artery sequentially. Surgical procedures were successfully accomplished and major perioperative complications did not occur. . PMID- 30279768 TI - Ruptured pseudo-aneurysm of the mitral-aortic intervalvular fibrosa - A 3D transesophageal echocardiographic depiction. AB - Pseudo-aneurysm of the mitral-aortic intervalvular fibrosa (MAIVF) is a rare complication of native or prosthetic valve endocarditis. Good imaging is the key to successful diagnosis of this rare entity. This report describes a pseudo - aneurysm of the MAIVF rupturing into left atrium in a patient with double valve replacement with special reference to 3-dimensional transesophageal echocardiographic imaging. . PMID- 30279769 TI - A rare case of eosinophilic granulomatosis with polyangiitis complicated with progressive pericardial effusion. AB - A 44-year-old woman had a 15-year history of asthma and had recently been treated for sinusitis and unidentified limb eruption. She had presented at a nearby clinic with inspiratory chest pain one week before hospitalization, and was diagnosed as having eosinophilic pneumonia based on peripheral blood eosinophilia and ground glass opacities in the right lung field, without pericardial effusion, as detected by chest computed tomography. She additionally presented with a feeling of chest tightness, and extensive pericardial effusion appeared within a week. She developed heart failure on admission, and we performed pericardiocentesis. We gave a clinical diagnosis of acute probable myopericarditis as the cause of pericardial effusion based on pleuritic chest pain, pericardial effusion, and elevation of cardiac enzymes, as well as eosinophilic granulomatosis with polyangiitis (EGPA) based on eosinophilia, her history of sinusitis, asthma, and migratory pulmonary opacities. We initiated oral prednisone 25 mg daily and pericardial effusion disappeared. In patients with EGPA, cardiac involvement is more serious than the involvement of other organs, and is associated with a poor prognosis. In this report we describe a rare case of EGPA complicated with progressive pericardial effusion and discuss the importance of the early diagnosis and treatment of EGPA. . PMID- 30279770 TI - Normalization of biventricular strain post steroid treatment of effusive constrictive pericarditis. AB - Peak left ventricular strain measured by speckle tracking echocardiography has previously been shown to normalize following pericardectomy in constrictive pericarditis, as indicated by an increase of the strain ratio between the lateral wall and septum. Here we present a case of effusive constrictive pericarditis treated with corticosteroids. Pre-treatment we observed reduced contractility of the lateral walls of both ventricles as measured by peak strain, with sparing of overall septal function, but with hypercontractility of the basal septal segment. Septal and lateral wall function normalized with corticosteroid treatment. Our observations from this case prompts investigation into the value of lateral/septal wall strain ratios in both ventricles for quantitatively monitoring the response of constrictive pericarditis to medical therapy. . PMID- 30279771 TI - Fistula formation following repair of a pseudoaneurysm of the mitral-aortic intervalvular fibrosa - A rare complication. AB - The mitral-aortic intervalvular fibrosa is an avascular fibrous structure connecting the mitral and aortic annuli that is prone to pseudoaneurysm formation. Pseudoaneurysm of the mitral-aortic intervalvular fibrosa is a known complication of many conditions such as infective endocarditis and valvular surgery. It requires surgical correction. Its long-term consequences are little known. We present in this report the case of a 62-year-old male with history of pseudoaneurysm of the mitral-aortic intervalvular fibrosa repair and redo mitral and aortic prosthetic valve replacements. After five years of asymptomatic follow up, the patient presented with sudden-onset heart failure. Echocardiographic investigation demonstrated two aorto-atrial fistulae at the site of his previous repair and adequate function of both prosthetic valves. The fistulae were repaired and the prosthetic valves were left in place. This represents a potential late surgical complication of pseudoaneurysm of the mitral-aortic intervalvular fibrosa. . PMID- 30279772 TI - Right ventricular mobile thrombus in end-stage hypertrophic cardiomyopathy. AB - We report the first case of a mobile right ventricular apical thrombus in hypertrophic cardiomyopathy in the absence of right ventricular apical aneurysm. An 87-year-old man who had been diagnosed as having hypertrophic cardiomyopathy presented with gross peripheral edema and exertional dyspnea. He had been on warfarin, beta-blockade, and diuretics. Electrocardiograms indicated progression of the disease with atrial fibrillation, low voltage and prominent Q waves in the left precordial leads. Echocardiograms revealed ventricular septal and apical hypertrophy, hypokinetic distal left ventricle, and dilated and severely hypokinetic right ventricle. A mobile thrombus (18 mm * 18 mm) was detected in the right ventricular apex. Cardiac computed tomography and magnetic resonance imaging confirmed a large thrombus in the right ventricular apex. Late gadolinium enhancement was present in the interventricular septum and distal segments of both ventricles, indicating myocardial fibrosis and scar. A dilated and poorly contracting right ventricle, particularly right ventricular apex, in end-stage hypertrophic cardiomyopathy, associated with stagnant blood flow in the apex, was hypothesized as being responsible for right ventricular apical thrombus formation in the absence of right ventricular aneurysm. . PMID- 30279773 TI - A case of in-stent restenosis with pathologically proven chronic inflammation seven years after sirolimus-eluting stent implantation. AB - A 67-year-old man was admitted to our hospital due to chest pain at rest. Seven years previously, the patient underwent percutaneous coronary intervention (PCI) of the left ascending artery and implanted sirolimus-eluting stent (SES). Coronary angioscopy (CAS) performed at that time showed a white plaque at the SES site. Two years after the first PCI, repeat CAS demonstrated light yellow plaques at the SES site. At the time of his presentation to our hospital, coronary angiography showed in-stent restenosis at the SES site, and CAS demonstrated the plaque rupture with presence of dense yellow plaque and various thrombi. After distal protection, drug-eluting balloon treatment was performed. Collected specimens from culprit sites included foamy macrophages, cholesterin crystals, neutrophils, and fibrin, suggesting that progressive neoatherosclerosis at the SES site triggered the acute coronary syndrome. This study highlights the importance of ensuring careful patient follow-up after SES implantation. . PMID- 30279774 TI - Primary cardiac rhabdomyosarcoma developed after receiving radiotherapy for left breast cancer 18 years prior. AB - The heart is an organ where primary malignant tumors rarely develop. In particular, the incidence of cardiac rhabdomyosarcoma (RMS) is extremely low. It has been reported that the risk of second malignant tumors in mediastinum is increased by radiotherapy in women with breast cancer. However, little is known about the association between irradiation to heart and cardiac RMS. Here, we report a case of a 68-year-old woman with primary cardiac RMS. She suddenly presented syncope at a workplace, and was taken to the emergency room at our hospital. Several imaging tests, including echocardiogram and cine magnetic resonance imaging, detected two tumors in the right ventricle (RV) and its outflow tract, which had almost obstructed the main trunk of the pulmonary artery (PA). To avoid sudden PA occlusion by the tumor, we emergently performed surgical excision of the tumors from the RV. Pathological analysis revealed that these tumors were embryonal type RMS. She had received radiotherapy after mastectomy for left breast cancer 18 years previously, and no recurrence of breast cancer had been detected. This cardiac RMS is considered as a second malignant tumor related to radiotherapy for breast cancer. . PMID- 30279775 TI - A case of unexpected early battery depletion caused by lithium cluster formation in implantable cardioverter-defibrillator. AB - Device failure from unexpected battery depletion is uncommon but can be life threatening. Lithium cluster formation at the cathode is a novel mechanism of sudden implantable cardioverter-defibrillator (ICD) battery depletion that was first reported in 2014. We report a rare case of a 78-year-old woman with an ICD battery failure due to lithium cluster formation. Although she had never received ICD therapy, the battery voltage had dropped from 2.9 V to 2.54 V (end of life) unexpectedly for only 2 days. The prevalence of this rare phenomenon was reported to be 0.004% in 2014. However, it had gone up to 0.21% in October 2016. Both device manufacturers and clinicians should be aware of this phenomenon, and remote monitoring systems and vibratory patient notifier alerts should be considered for early detection and early treatment. . PMID- 30279776 TI - Lex parsimoniae. AB - We present a noteworthy case of dual pathology in a 62-year-old female with recurrent chest pains and extensive cardiac risk factors. From computed tomography coronary angiography, a left anterior descending artery lesion was identified and successfully revascularized with a drug-eluting stent. Due to persistent chest pain, further investigation revealed a descending aortic dissection, which was conservatively managed. This case highlights the potential challenges of diagnosis in dual pathologies and emphasizes initiating appropriate investigations. . PMID- 30279777 TI - Tricuspid stenosis: An emerging disease in cardiac implantable electronic devices era. Case report and literature review. AB - Tricuspid valve dysfunction and in particular tricuspid stenosis has recently been described secondary to cardiac implantable electronic devices. The valve is subjected to different mechanisms of injury related to the endocardial lead passing through its plane. The lead can form a loop or perforate one of the leaflets and initiate inflammatory response and fibrotic changes. Multimodality cardiac imaging is required to diagnose this clinical entity and decide on the best treatment plan. Here we present a case of a young female who developed tricuspid stenosis secondary to permanent pacemaker lead that was implanted 24 years before. We performed a review for all cases reported in the literature with a similar condition and various treatment approaches. . PMID- 30279778 TI - Acute myocardial infarction due to left main embolization of calcified tissue from mitral valve subapparatus. AB - An 81-year-old woman was referred for primary angioplasty due to a myocardial infarction. Upon her arrival, the patient was in cardiogenic shock. Coronarography revealed a large filling defect within the left main coronary artery. Thromboaspiration was performed, obtaining thrombotic material and tissue of different consistencies. Balloon angioplasty in the left anterior descending and left main arteries was performed, resulting in incomplete reperfusion, leading to irreversible electromechanical dissociation. Analysis of the aspirated material was consistent with thrombus, atheroma, and calcified tissue. Autopsy revealed a heavily calcified mitral valve, and distal embolization of amorphous material in the microvasculature identical to that found in the mitral valve subapparatus. . PMID- 30279779 TI - Dual loop reentrant tachycardia with a combination of a localized reentry and a macro-reentry. AB - A 78-year-old woman presented 2 years after mitral valve replacement for rheumatic mitral stenosis with cardioversion-resistant atrial tachycardia (AT). Dual-loop AT was identified by activation mapping with the RhythmiaTM system (Boston Scientific, Marlborough, MA, USA) and confirmed by entrainment-mapping; one circuit with localized re-entry turned around the scar on the posterior left atrium and the other circuit, which was macro re-entrant, turned around the left superior pulmonary vein (LSPV) using the PV-carina, the ridge beween the left atrial appendage and the LSPV, and the roof. The two wavefronts fused on the posterior wall close to the LSPV. Radiofrequency ablation of an area of slow conduction on the posterior wall changed the tachycardia to roof-dependent AT which was then terminated by completion of a roof line. . PMID- 30279780 TI - Successful hybrid treatment with endovascular aorto-iliac revascularization and coronary bypass surgery in a patient with an advanced complex polyvascular disease. AB - A 72-year-old Japanese man was admitted to our hospital for effort chest pain and bilateral claudication. He was diagnosed as having severe ischemic heart disease and chronic bilateral aorto-iliac occlusions (Leriche syndrome) by a diagnostic angiography. Manifest collaterals via bilateral internal thoracic arteries (ITA) supplied sufficient blood flow for his lower limbs. We planned a two-stage operation for both the severe coronary artery disease and peripheral artery occlusive disease. He first underwent endovascular therapy (EVT) for bilateral aorto-iliac occlusion. One month later he underwent coronary artery bypass grafting (CABG) that was carried out for three coronary arteries with bilateral ITAs, also known as the internal thoracic artery, and the gastroepiploic artery. His chest symptoms and claudication were completely relieved and he was discharged uneventfully. We hereby suggest that EVT can be a safe, effective, and minimally invasive treatment to enable the patient to undergo CABG with all arterial grafts. . PMID- 30279781 TI - Coronary artery bypass graft pseudoaneurysm from saphenous vein graft stent fracture. AB - Saphenous venous graft (SVG) pseudoaneurysms are a rare complication of coronary artery bypass grafting (CABG). An 85-year-old man with CABG and a distal SVG stent presented with dyspnea. Chest computed tomography (CT) revealed a large partially thrombosed pseudoaneurysm at the distal SVG with stent fracture. Endoluminal exclusion of the distal SVG pseudoaneurysm using a covered stent was performed. Follow-up chest CT and angiography showed persistent pseudoaneurysm filling and enlargement. The SVG proximal to the pseudoaneurysm was embolized with coils to reduce rupture risk. Following embolization, the patient's left ventricular ejection fraction was moderately depressed but the patient remained stable and was discharged. . PMID- 30279782 TI - Disopyramide as rescue treatment in a critically ill infant with obstructive hypertrophic cardiomyopathy refractory to beta blockers. AB - Hypertrophic obstructive cardiomyopathy (HOCM) is the most common known cause of sudden death in children beyond infancy and in young athletes. Cases reported indicate that steroid-induced HOCM is usually a benign disorder. The normalization of cardiac morphological changes and clinical signs observed after the discontinuation of steroid therapy indicates that the effects on cardiac muscle are dose-dependent and reversible. However, the management of patients with symptomatic-HOCM presenting in infancy represents a major challenge because left ventricular outflow tract obstruction is a major risk factor associated with increased mortality in pediatric patients. We report a critically ill infant with steroid-induced HOCM resistant to beta-blockers who was successfully treated with disopyramide without relevant adverse events. Adult guidelines and pediatric experts suggest pharmacological therapy with beta-blockers or verapamil as the first- and second-line approach. However, these drugs are not always an option, especially in critical patients, hence, alternative therapeutic options are required. For these cases, disopyramide could be an alternative drug in spite of the little evidence on its safety and efficacy in pediatric patients. Our experience supports this cause, and the need for prospective studies on its use in the management of hypertrophic cardiomyopathy in children. . PMID- 30279783 TI - Left superior pulmonary venous thrombosis complicated with splenic infarction after video-assisted thoracoscopic left upper lobectomy. AB - A 72-year-old man underwent video-assisted thoracoscopic left upper lobectomy for small cell lung cancer. After 16 days, he experienced epigastric abdominal pain and vomiting, and was taken by ambulance to our hospital. Contrast-enhanced computed tomography (CT) showed a propagation of thrombus in the stump of the left superior pulmonary vein (LSPV) complicated with splenic infarction. The patient received anticoagulation therapy with heparin and warfarin, and further progression of the thrombus or any systemic embolic event was not observed during hospitalization. Here, we report a patient presenting with LSPV thrombosis complicated with splenic infarction after video-assisted thoracoscopic surgery (VATS), and describe several months follow-up CT imaging results after administration of an oral anticoagulation therapy. . PMID- 30279784 TI - Acute necrotizing eosinophilic myocarditis complicated by complete atrioventricular block promptly responded to glucocorticoid therapy. AB - Acute myocarditis is frequently accompanied with conduction disturbances. Complete atrioventricular (AV) block may occur in acute myocarditis, but rarely in eosinophilic myocarditis. Acute necrotizing eosinophilic myocarditis, the most severe form of eosinophilic myocarditis, is generally fatal, and rarely complicated by complete AV block. We report a case of a 66-year-old woman with acute necrotizing eosinophilic myocarditis who presented with general malaise and nausea. She suddenly fell into cardiogenic shock because of complete AV block and worsened heart failure. Ultrasound cardiography revealed pericardial effusion, edematous myocardium, and reduced contractility of the left ventricle. The biopsied specimens showed marked interstitial infiltration with predominant eosinophils accompanied with myocardial necrosis. Oral administration of glucocorticoid in moderate dose promptly resolved the complete AV block, her clinical symptoms, and cardiac function. We recognized that acute necrotizing eosinophilic myocarditis can be complicated by complete AV block. Steroid therapy could be effective in the treatment of conduction disturbance as well as myocardial inflammation. . PMID- 30279785 TI - Left atrial ball thrombus after edge-to-edge mitral valve repair. AB - A thrombus can develop in the left atrium during atrial fibrillation because the loss of contractile function leads to blood flow stasis. Anticoagulation therapy is indicated for prevention of systemic embolism, usually maintaining an international normalized ratio between 2 and 3. Rarely a massive thrombosis develops in the atrium resulting in a peduncolated ball valve thrombus or in a free-floating thrombus. These two conditions are characterized by variables in the physical findings. Such masses are hazardous and upon discovery surgical treatment, often in emergency, is mandatory. We present here the case of a patient who developed an unnoticed huge left atrial ball thrombus despite warfarin therapy after previous mitral valve surgery. . PMID- 30279786 TI - Improvement of pulmonary arterial hypertension following medication and shunt closure in a BMPR2 mutation carrier with atrial septal defect. AB - Mutation of the BMPR2 gene is the most common genetic cause of pulmonary arterial hypertension (PAH). Although there have been some reports of BMPR2 mutation carriers among PAH patients with congenital heart disease, there have been few reports of their treatment. Here, we describe a 13-year-old female BMPR2 mutation carrier who presented with heritable PAH and atrial septal defect (ASD). She complained of fatigue, and cardiac catheterization showed a mean pulmonary artery pressure (PAP) of 56 mmHg, a pulmonary vascular resistance (PVR) of 8 Wood units and a pulmonary to systemic blood flow ratio (Qp/Qs) of 1.3. Following 2 years of medication therapy, the mean PAP had decreased to 30 mmHg, the Qp/Qs had increased to 2.7, and her symptoms persisted. We closed the ASD interventionally, and her symptoms improved after closure. Medication therapy was continued. Four years after closure, the PAH had improved with a mean PAP of 20 mmHg and a PVR of 3.1 Wood units. To the best of our knowledge, this is the first report of PAH improvement following medication and ASD closure in a BMPR2 mutation carrier with heritable PAH. ASD closure following medication appears to be effective in some ASD patients with heritable PAH. . PMID- 30279787 TI - Subacute effusive-constrictive pericarditis: Echocardiography-guided diagnosis and management. AB - A 49-year-old man presented with flu-like symptoms of two weeks. Electrocardiogram showed diffuse ST elevation. Blood samples revealed severe renal failure and moderate inflammatory results. Echocardiogram showed large pericardial effusion, dilated inferior vena cava, but no right ventricular collapse. The patient underwent hemodialysis, after which he developed clinical signs of cardiac tamponade with echocardiographic features of collapse of the right ventricle. Pericardial drainage was then performed revealing purulent fluid of 800 ml. Streptococcus agalactiae was found in the cultures of urine, blood, and pericardial fluid. Despite removal of the pericardial fluid, echocardiogram failed to show any improvement in dilated inferior vena cava and estimated right atrial pressure remained elevated. Thus, a diagnosis of subacute effusive constrictive pericarditis was made. Following antibiotic treatment for purulent pericarditis, early pericardiectomy was performed under transesophageal echocardiographic monitoring which successfully guided surgeons to careful removal of thick and adhesive visceral pericardium as well as an additional Waffle procedure resulting in significant clinical and hemodynamic improvement. Echo-guided approach is most practical in establishing the diagnosis of effusive constrictive pericarditis and also most helpful in obtaining successful surgical results. . PMID- 30279788 TI - Organophosphate poisoning presenting as out-of-hospital cardiac arrest: A clinical challenge. AB - Out-of-hospital cardiac arrest (OHCA) remains a challenge for physicians since effective management and definitive salvage depend upon correct determination of the etiology and the extent of injury. Definitive diagnosis of organophosphate poisoning (OP) requires physicians' clinical awareness of a typical toxidrome, that is, characteristic signs and symptoms of poisoning, and laboratory confirmation. Here we report a case of an OHCA patient with OP, which was initially misdiagnosed as an acute ST segment elevation myocardial infarction based on the patient's medical history and clinical manifestations. . PMID- 30279789 TI - Delayed cardiac tamponade 8 months after pulmonary vein isolation. AB - We herein report the case of a 55 year-old male who underwent pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation. From 8 months after PVI, exertional dyspnea rapidly appeared. When he was referred to our hospital, massive pericardial effusion was observed by transthoracic echography. The pericardiocentesis revealed bloody pericardial effusion, and improved symptoms. Although aortic dissection, autoimmune disease, infection, metastatic pericardial tumor, primary pericardial tumor, and malignant neoplasm were considered as differential diagnosis, the cause of pericardial effusion failed to be found. From these findings, the cause of hemorrhagic pericardial effusion was considered delayed cardiac tamponade induced by PVI performed 8 months earlier. . PMID- 30279790 TI - A case of ventricular fibrillation as a consequence of capecitabine-induced secondary QT prolongation: A case report. AB - Capecitabine is an oral fluoropyrimidine which can prolong QT interval. However, there have been no reports that capecitabine induced ventricular fibrillation (VF) due to secondary QT prolongation in patients with no structural heart disease. A 39-year-old woman developed VF during the chemotherapy of capecitabine for colon cancer. At the administration, corrected QT interval (QTc) was prolonged to 559 ms despite no evidence of organic heart disease. Discontinuation of capecitabline normalized the QTc (414 ms). During the follow-up of eight years, neither the QTc prolongation nor the recurrent VF has been detected. We report the rare case of capecitabine-related VF without any organic heart disease. . PMID- 30279791 TI - Therapeutic potential of tofogliflozin on nephrotic syndrome secondary to diabetic nephropathy. AB - Diabetic nephropathy (DN) is a critical complication in patients with type 2 diabetes and regarded as a progressive disorder with a poor prognosis. The degree of albuminuria is associated closely with worse renal and cardiovascular outcomes. It is therefore important to achieve remission of proteinuria to avoid progression of DN and improve outcomes. Although a recent clinical trial demonstrated that a sodium glucose cotransporter 2 (SGLT2) inhibitor could improve cardiovascular and renal outcomes in cardiovascular high risk patients with type 2 diabetes, little is known whether SGLT2 inhibitors have favorably renal effects in patients with nephrotic syndrome associated with DN. Herein, we report a 54-year-old patient with refractory nephrotic syndrome accompanied by diabetic nephropathy. Tofogliflozin, a SGLT2 inhibitor, successfully increased urine volume, and reduced body weight, HbA1c, and urinary protein excretion (10.8 to 2.6 g/day) during 24 weeks. His severe edema also was diminished after administration of tofogliflozin. This case indicates that an SGLT2 inhibitor may be a useful choice in the treatment of patients with diabetic nephropathy and the nephrotic syndrome. . PMID- 30279792 TI - Differences of plaque characterization of high-intensity and non high-intensity plaques on non-contrast T1-weighted magnetic resonance imaging using angioscopy and optical coherence tomography. AB - Coronary high-intensity plaques (HIPs) visualized by non-contrast T1-weighted imaging (T1WI) in cardiac magnetic resonance (CMR) were associated with coronary events. We report a case of a 68-year-old man with an old myocardial infarction. He had undergone CMR to exclude new coronary artery disease, because he sometimes had an atypical chest symptom. The moderate stenosis in the right coronary artery (RCA) showed non HIP on non-contrast T1WI. We observed HIP in the proximal left anterior descending artery (LAD) without significant stenosis. Non HIP lesion in the RCA showed fibrous and calcified plaque without thrombus by optical coherence tomography (OCT) and angioscopy. On the other hand, the HIP lesion in the LAD showed lipid plaque with thrombus by OCT, and yellow plaque with mobile mixed thrombus by angioscopy. . PMID- 30279793 TI - An adult case of Bland-White-Garland syndrome with collaterals from giant right coronary artery and bronchial artery. AB - Bland-White-Garland syndrome (BWG) is a congenital heart disease characterized by anomalous origin of left coronary artery from main pulmonary artery. The anomaly causes significant myocardial ischemia, mitral insufficiency, and high infant mortality. Several investigators have reported that the subjects who survived to adulthood showed extensive collateral flow from right coronary artery (RCA). We report a case of newly diagnosed BWG in an elderly patient who had well-developed collaterals from aneurysmal giant RCA and bronchial artery, which were identified by coronary angiography with multi-detector computed tomography. . PMID- 30279794 TI - Occasionally increased 18F-fluorodeoxyglucose uptake in apical hypertrophic cardiomyopathy with mid-ventricular obstruction. AB - We report on a 77-year-old man who was diagnosed with apical hypertrophic cardiomyopathy (HCM) with mid-ventricular obstruction. He had a cured hepatitis C infection. We detected occasionally increased 18F-fluorodeoxyglucose (18F-FDG) uptake on whole-body positron emission tomography (PET)/computed tomography (CT) performed to examine the involvement of bladder carcinoma. 18F-FDG-PET was restudied following specific preparation involving an 18-h low-carbohydrate diet and following 15-h fasting plus heparin pre-administration. Increased uptake of 18F-FDG was observed reproducibly in the hypertrophic apical to mid left ventricular myocardium, with a maximum standardized uptake value of 6.2. In contrast, relatively lower 18F-FDG-uptake areas tended to match areas of late gadolinium enhancement on cardiac magnetic resonance (CMR). Histopathological examination of myocardial biopsy showed disarried hypertrophic myocytes with cellular infiltration. Increased uptake of 18F-FDG may reflect the phenomenon of increased glucose utilization in hypertrophied myocardium. The increasing clinical utility of whole-body PET/CT for evaluating malignancies may increase the detection of occasional abnormal 18F-FDG uptake in the heart. It is necessary to clarify that 18F-FDG myocardial PET in combination with CMR may provide a more detailed risk assessment in patients with HCM. . PMID- 30279795 TI - Replacement myocardial fibrosis at the site of late gadolinium enhancement on magnetic resonance imaging in a patient with diffuse cutaneous systemic sclerosis: An autopsy report. AB - Late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) is a well known finding indicative of cardiac involvement in systemic sclerosis (SSc heart). However, few studies have reported the precise histopathology at the site of LGE. We present an autopsy report of a 51-year-old man diagnosed with diffuse cutaneous SSc according to a systematic diagnostic workup, including skin biopsy. CMR indicated left ventricular (LV) dilatation and broadly distributed subendocardial LGE in the LV walls. The patient was treated with methylprednisolone pulse therapy because of multiple episodes of ventricular tachycardia, whereas he subsequently died of left heart failure. An autopsy study revealed broad subendocardial replacement fibrosis, concomitant with the distribution of LGE on CMR, without inflammatory or edematous changes. Notably, myocardial fibrosis was evident around the intramural coronary arteries, although the arteries themselves were intact. These findings demonstrated that broad subendocardial LGE on CMR reflected replacement myocardial fibrosis in a patient with diffuse cutaneous SSc. These clinicopathological observations suggested that spasms in the intramyocardial arteries or the cardiac Raynaud's phenomenon may have provoked broad subendocardial fibrosis of the LV walls. . PMID- 30279796 TI - "Slipstream technique"-New concept of intravascular ultrasound guided wiring technique with double lumen catheter in the treatment of coronary total occlusions. AB - Intravascular ultrasound (IVUS)-guided guidewire manipulation technique is often useful to cross the lesion of chronic total occlusion (CTO) antegradely and solve retrograde CTO failure cases. However, this technique is usually complex because we need many devices and it requires many steps. Some steps usually take time and/or sometimes create a large dissection space which cause the procedure to fail. To overcome a weakness in this technique, we introduce the new IVUS-guided wiring technique with double lumen catheter named "Slipstream technique" here. This technique is simple, easy, and associated with less injury. It will be helpful for penetrating into the true lumen from the subintimal space with a guidewire correctly and safely. . PMID- 30279798 TI - Percutaneous closure of a giant pulmonary arteriovenous malformation using multiple devices. AB - Percutaneous device closure is an established method to treat pulmonary arteriovenous malformation (PAVM). This report describes the case of a 23-year old man with hereditary hemorrhagic telangiectasia (HHT) presenting with dyspnea and hypoxia. The patient was found to have a giant left-sided PAVM. The patient underwent percutaneous closure of PAVM with multiple devices with a good outcome. At 12-month follow up, the patient was asymptomatic with near complete obliteration of the arteriovenous malformation. . PMID- 30279797 TI - A rare case of acute myocardial infarction with a non-specific symptom in a young female with systemic lupus erythematosus. AB - A 31-year-old female with an 18-year history of systemic lupus erythematosus (SLE) complained of epigastralgia and consulted the emergency outpatient department at our hospital. Her physical examination revealed tenderness at the scrobiculus cordis, which was a non-specific symptom of coronary heart disease (CHD). We ultimately gave a diagnosis of acute myocardial infarction based on coronary angiography and performed percutaneous coronary intervention. Although pre-interventional intravascular ultrasound demonstrated distinct atherosclerotic lesions in the coronary arteries, there were no atherosclerotic lesions in other systemic arteries. Although CHD in young SLE patients is a significant cause of morbidity and premature death, it tends to be misdiagnosed because their symptoms may be non-specific. In addition, this case highlights the fact that even SLE patients with no systemic atherosclerosis are at risk for the development of CHD. . PMID- 30279799 TI - Percutaneous isolation of left atrial appendage thrombus. AB - Most physicians regard left atrial appendage (LAA) thrombus as a contraindication for LAA occlusion due to risk of distal embolization which is a serious complication. Here we report a case of successfully implanted Amplazter cardiac plug without complication in elderly patients having LAA thrombus with recurrent embolic events despite oral anticoagulants for prevention of thromboembolic events. . PMID- 30279800 TI - A daytime normotensive patient with nocturnal hypoxia-induced hypertension and severe obstructive sleep apnea. AB - This is the case of a 60-year-old male. He had no past medical history at a regular medical check-up. According to findings at the regular medical check-up, he was obese (body mass index, 32.8 kg/m2), and had short neck, small jaw, and low soft palate; therefore, it was suspected that he may have sleep-disordered breathing. Blood pressure (BP) at the medical check-up was 121/80 mmHg, and the results of electrocardiogram and chest radiography were normal. Blood test data at the medical check-up indicated abnormality of lipid metabolism and hyperuricemia. No other abnormalities were found. It became clear that he became sleepy during daytime at an additional medical interview. Accordingly, he was diagnosed as having severe obstructive sleep apnea (OSA) with apnea-hypopnea index 65.3/h and arousal index 64.4/h by polysomnography. The oxygen-triggered nocturnal BP monitoring that was conducted at home around the same time indicated remarkable hypoxia-induced hypertension (Day 1: hypoxia-peak nocturnal BP 181/117 mmHg, Day 2: hypoxia-peak nocturnal BP 204/137 mmHg). The patient recognized the risk of OSA by visualizing the hypoxia-induced hypertension; therefore, introduction of continuous positive airway pressure (CPAP) therapy for severe OSA was smooth. As the results of CPAP therapy, we could confirm disappearance of hypoxia-induced hypertension. . PMID- 30279801 TI - An unusual cause of myocardial ischemia: Compression of a left internal mammary artery grafting to the left anterior descending artery by a pacemaker lead. AB - An 83-year-old patient, with prior history of coronary artery disease treated by coronary-artery bypass graft with left internal mammary artery (LIMA) to the left anterior descending artery (2001) and angioplasty of the right coronary artery (2012) and prior pacemaker through left subclavian vein (2014), was referred to coronary angiography for an anterior silent ischemia. It found no evolving lesion on the native coronary artery network (compared with 2012 review) but revealed an external compression of the LIMA bridge by the pacemaker lead. Conservative treatment was chosen rather than explantation and reimplantation of stimulus material or LIMA angioplasty. . PMID- 30279803 TI - Streptococcus pyogenes meningitis and endocarditis in a patient with prosthetic mitral valve. AB - Streptococcus pyogenes is commonly found in cutaneous and pharyngeal infections, but rarely causes meningitis and endocarditis. We report a 77-year-old male with history of prosthetic mitral valve, presenting with meningitis and endocarditis secondary to S. pyogenes. We aim to raise awareness among clinicians of rare infectious etiology as the cause of endocarditis and meningitis, and importance of prompt diagnosis in ensuring success of medical treatment and long-term survival. . PMID- 30279802 TI - Coronary artery stenting in acute coronary syndrome associated with giant cell arteritis. AB - Coronary vasculitis is a rare but devastating complication of giant cell arteritis, otherwise known as temporal arteritis. Originally named for its propensity to attack the superficial temporal arteries, it is now recognized that it commonly involves a number of medium and large arteries throughout the body. Here we describe two cases of giant cell arteritis affecting the coronary arteries, one discovered at post-mortem and one which was successfully treated with immunosuppressive therapy and drug-eluting coronary stents. . PMID- 30279804 TI - A case of premature ventricular complexes/ventricular tachycardia from the left ventricular outflow tract successfully ablated from the distal great cardiac vein. AB - We experienced a 41-year-old male with premature ventricular complexes/ventricular tachycardia from the left coronary cusp and distal great cardiac vein of the left ventricular outflow tract successfully treated by radiofrequency catheter ablation utilizing a 3D mapping system (EnSiteNavX/VelocityTM Cardiac Mapping System, St. Jude Medical, St. Paul, MN, USA) without any complications. . PMID- 30279805 TI - Development of an iatrogenic aneurysm nine months after pacemaker implantation: Consideration of causes and treatment. AB - Careful technique is required in pacemaker implantation to avoid serious iatrogenic complications. A 70-year-old woman on an anticoagulant agent underwent pacemaker implantation. Nine months after implantation, a 35-mm pulsatile mass appeared just near the cranial edge of the generator. An iatrogenic pseudoaneurysm was suspected because ultrasonography showed communication with the blood stream through tiny artery. The resected mass proved to be a pseudoaneurysm. This was a rare case of iatrogenic delayed pseudoaneurysm appearing nine months later. It is essential to keep in mind the risk of pseudoaneurysm after pacemaker implantation, especially when the patient takes anticoagulant agents. . PMID- 30279806 TI - Change in type of sleep-disordered breathing from predominant central to obstructive sleep apnea following coronary artery bypass grafting. AB - We report the case of a 67-year-old overweight man with reduced left ventricular ejection fraction (LVEF) due to myocardial infarction. He had an implantable cardioverter defibrillator (ICD) for frequent episodes of ventricular tachyarrhythmia and was initiated into adaptive-servo ventilation therapy for severe central sleep apnea (CSA), which was not suppressed by continuous positive airway pressure (CPAP). Since he still had several episodes of appropriate ICD therapies, coronary angiogram was performed, and severe three-vessel disease was found. He then underwent coronary artery bypass grafting (CABG). After CABG, his LVEF did not improve (from 29 to 25%); however, the B-type natriuretic peptide level decreased (from 560 to 330 pg/mL). Although the apnea-hypopnea index did not change (49.4 before and 55.1/h after CABG), his CSA converted to predominant obstructive sleep apnea accompanied by a shortening of the lung-to-finger circulation time (from 43 to 29 s) 2 weeks after CABG, which was completely suppressed by CPAP. . PMID- 30279807 TI - Contrast induced spinal myoclonus after percutaneous coronary intervention. AB - We present a case of a 77-year-old man diagnosed with contrast-induced spinal myoclonus following primary percutaneous coronary intervention. After being admitted with a diagnosis of anteroseptal myocardial infarction, he underwent primary percutaneous coronary intervention to the left anterior descending artery and was prescribed aspirin, clopidogrel, and intravenous heparin. The following day he developed non-intentional irregular jerky movements confined to the truncal area. In view of rhythmic jerking confined to muscles innervated by a restricted segment of the spinal cord, resistance to supra-spinal influences and voluntary action, and no preceding electroencephalography activity in the contralateral sensorimotor cortex, a diagnosis of spinal myoclonus was made. Spinal myoclonus is a rare entity in which myoclonic movements occur in muscles originating from few (segmental), or many adjacent spinal motor roots (propriospinal). Structural lesions are found in the majority of cases but the actual pathophysiology is still unknown. Contrast-induced spinal myoclonus is an even rarer phenomenon with few published reports. We describe postulated mechanisms and the management of this phenomenon. . PMID- 30279808 TI - Successful revascularization of advanced coronary artery disease associated with pseudoxanthoma elasticum. AB - Pseudoxanthoma elasticum (PXE) is caused by loss-of-function mutations of the ATP binding cassette subfamily C member 6 gene. A 58-year-old man was diagnosed as having PXE based on typical findings in orbital and skin biopsies. Coronary computed tomography (CT) showed severe coronary stenosis in the proximal right coronary artery (RCA), and chronic total occlusion (CTO) of the mid left anterior descending coronary artery (LAD) with bridging collaterals. Coronary angiography revealed 99% stenosis in the RCA (#1) and CTO in the mid LAD (#7) with well developed collaterals from the LAD to the RCA. We performed percutaneous coronary intervention (PCI) and achieved complete revascularization. Intravascular ultrasound (IVUS) showed a superficial high echoic component around the vessels throughout the length of coronary arteries including non-stenotic regions. In the IVUS findings, the main cause of stenosis of the RCA lesion was large amounts of plaque, and the cause of the CTO in the LAD was coronary negative remodeling. In this case, coronary CT was clinically useful in the identification of ischemic heart disease. Since IVUS demonstrates variable findings in each coronary artery lesion and the morphologic characteristics might alter the strategy of PCI, IVUS should be performed at the time of PCI in PXE patients. . PMID- 30279809 TI - Coronary artery stent dislodgement and aortic dissection in a patient with a severely calcified lesion in the proximal right coronary artery. AB - In atherosclerosis progression, calcium deposition may have an impact on the natural history of coronary atherosclerosis, and the amount of calcium may affect the success rate of percutaneous coronary intervention (PCI). Coronary stent dislodgement does not commonly occur in the modern PCI era; however, it may lead to fatal death. If it occurs, retrieval of a dislodged stent can be performed either surgically or percutaneously using a variety of retrieval techniques, including inflating a catheter balloon distal to the undeployed stent, twirling 2 wires around the stent, a loop snare, or forceps. Here, we report a rare case that coronary artery stent dislodgement and aortic dissection simultaneously occurred during PCI for a severely calcified lesion in the proximal right coronary artery with shepherd's crook morphology. The situation was successfully rectified by using balloons to deploy the stent, as well as by applying an additional stent and minimizing the contrast used to treat aortic dissection. Learning objective: During percutaneous coronary intervention (PCI), stent dislodgement and aortic dissection are extremely rare, but life-threatening complications. In this rare case of simultaneous stent dislodgement in the coronary artery and aortic dissection during PCI for a severely calcified lesion in the right coronary artery with shepherd's crook morphology, the situation was successfully rectified by using balloons to retrieve and deploy the stent, as well as by applying an additional stent and minimizing the contrast used to treat aortic dissection. PMID- 30279810 TI - Successful early steroid and anticoagulant treatment for Loeffler's endocarditis related to eosinophilic granulomatosis with polyangiitis. AB - Loeffler's endocarditis is cardiac damage mediated by hypereosinophilia with a poor prognosis. A 45-year-old woman with Loeffler's endocarditis caused by eosinophilic granulomatosis with polyangiitis had hypereosinophilia (blood eosinophil count 32.4 * 109/L) and left ventricular systolic and diastolic dysfunction (left ventricular ejection fraction 45%, e' 5.1 cm/s). Echocardiography showed a left ventricular apical thrombus (32 * 30 mm). The cardiac magnetic resonance imaging scan showed a subacute thrombus (an iso intensity area on T1-weighted images and a high-intensity area on T2-weighted images). We administered prednisolone and anticoagulant immediately. The eosinophil count rapidly decreased. After 8 weeks, the thrombus gradually decreased in size (28 * 17 mm) and cardiac function improved (left ventricular ejection fraction 58%, e' 8 cm/s). On the follow-up cardiac magnetic resonance imaging scan, the thrombus gradually became organized (the high-intensity area on T2-weighted images became iso-intense). The subendocardial late gadolinium enhancement showed fibrosis only in a small part of the anterior left ventricular wall. Early steroids and optimal anticoagulant therapy may improve cardiac function and prognosis. Additionally, cardiac magnetic resonance imaging may be an important modality for diagnosis and follow-up. . PMID- 30279811 TI - Clinicopathological features of bi-ventricular cardiac intimal sarcoma-Report of an autopsy case. AB - We present the clinicopathological characteristics of primary cardiac intimal sarcoma which was widely spread throughout bi-ventricles. The patient had a wide range of clinical manifestations starting with left-sided heart failure then finally developing refractory right-sided heart failure during 44 months of follow-up. . PMID- 30279812 TI - Primary cardiac angiosarcoma. Histopathology imaging correlation. AB - We report a novel observation of a cardiac hemangioma possible transformation into cardiac angiosarcoma. This report should give a new insight on the pathogenesis of the tumor, always thought to have a de-novo genesis. We emphasize in our report the value of combining imaging modalities to examine the anatomic and metabolic properties of cardiac tumors providing a valuable tool for comprehensive assessment. . PMID- 30279813 TI - Stent collapse caused by balloon occlusion and aspiration system in saphenous vein graft intervention. AB - We present the case of an 82-year-old male patient with unstable angina pectoris referred for percutaneous coronary intervention in the saphenous vein graft (SVG) to left circumflex coronary artery. An everolimus-eluting cobalt chrome stent was successfully deployed, using an embolic protection device with balloon occlusion and aspiration system. During the procedure of aspiration thrombectomy, the deployed stent unexpectedly collapsed. We re-dilated the collapsed stent using the same distal protection and aspiration system. However, the stent collapsed again during the aspiration procedure. As we could successfully re-dilate the collapsed stent using the same balloon occlusion and aspiration system after pulling the guide catheter out from the ostium of SVG, we concluded that the collapse of the stent was caused by the excess negative pressure generated by the distal occlusion and aspiration procedure under the completely wedged guide catheter into the ostium of SVG. We believe this is the first report of stent collapse due to excess negative pressure during aspiration thrombectomy. . PMID- 30279814 TI - Late rupture of artificial neochordae associated with hemolytic anemia. AB - A 63-year-old man, status post-mitral valve repair for severe mitral regurgitation secondary to ruptured chordae of the anterior leaflet, was admitted seven years after surgery because of a recent history of hematuria. A new apical pansystolic murmur was audible. Hemoglobin level was 5.7 g/dL. Results of other hematologic studies and a peripheral blood smear were indicative of mechanical hemolysis. Transesophageal echocardiography showed a high-velocity jet of mitral regurgitation that directly collided with the annuloplasty ring. At re-operation, one of the artificial neochordae to A2 and A3 segments was found to be disrupted. The mitral valve was replaced with a 33/31 mm On-X valve. Hemolytic anemia disappeared immediately after surgery. Although mitral valve repair with artificial neochodae has been shown to have long-term durability, it should be recognized that artificial neochordae may rupture a long time after mitral valve repair. Also, although hemolytic anemia is known as an early complication after mitral valve repair, it is worth knowing that hemolytic anemia may occur as a late complication after mitral valve repair. Continuous long-term monitoring of the patients after mitral valve repair is recommended. . PMID- 30279815 TI - Congenital left main coronary artery atresia presenting as syncope and generalized seizure during exercise in a 13-year-old boy. AB - We report the case of a 13-year-old boy who, while running in a school gymnasium, experienced sudden syncope and seizure. CPR was started immediately, and an automated external defibrillator (AED) was attached, but shock was not induced. He was referred to our hospital for loss of consciousness and intermittent general tonic-clonic seizure. A 12-lead electrocardiogram showed normal sinus rhythm and no ST-T wave abnormalities. Echocardiography showed normal structural heart and normal cardiac function. On the second day of hospitalization, AED electrocardiogram showed complete atrioventricular (AV) block at syncope and seizure. After the patient recovered from this neurological state, we performed the treadmill exercise test, and it did not show ST-T wave abnormalities or AV block, and he did not complain of chest pain. Coronary angiography showed atresia of the left main trunk and the collateral vessel from the right coronary artery connected to the left coronary artery. He was diagnosed with congenital left main coronary artery atresia. We began administration of calcium antagonist and aspirin to prevent a coronary artery spasm and then performed a coronary artery bypass graft (CABG) to prevent sudden cardiac death. After CABG, he has had no syncope episodes at rest or during light exercise. . PMID- 30279816 TI - Transfemoral implantation of Edwards SAPIEN-XT(r) transcatheter heart valve in a degenerated tricuspid bioprosthesis. AB - We report on a percutaneous transcatheter valve-in-valve implantation (Edwards SAPIEN-XT(r)) (Edwards Lifesciences Corp., One Edwards Way Irvine, CA 92614) in a 50-year-old i.v. drug user with a history of biological tricuspid valve replacement (Perimount 31 mm) (Edwards Lifesciences Corp., One Edwards Way Irvine, CA 92614) due to tricuspid valve endocarditis five years earlier. Re operation was considered unfavorable due to general and specific risk factors. The case was discussed by the heart team. Obviously, some type of valve replacement was required. Given the high risk of tricuspid valve re-operation in general and the specific risk factors of the patient (New York Heart Association functional class III, reduced right ventricular function, continued drug abuse, active hepatitis C and human immunodeficiency virus infection, suspected non compliance, unfavorable social background) the consensus was to attempt percutaneous transcatheter valve-in-valve implantation. Implantation of an Edwards-SAPIEN-XT(r) valve (Edwards Lifesciences Corp., One Edwards Way Irvine, CA 92614) in tricuspid position was successfully performed and the patient was transferred to the ward on day 2, completely free of symptoms. Pre-discharge echocadiographic control on day 6 again confirmed adequate position and regular function of the Edwards-SAPIEN-XT(r) valve (Edwards Lifesciences Corp., One Edwards Way Irvine, CA 92614) without any signs of regurgitation or stenosis. . PMID- 30279817 TI - Focal right atrial tachycardia with three foci in a patient with polymyositis. AB - Cardiac involvement secondary to polymyositis is not infrequent. In addition, it sometimes presents various forms of arrhythmia, including atrial tachycardia (AT). A 72-year-old female who had 5-years history of polymyositis was referred to our clinic with symptomatic supraventricular tachycardia with 2:1 atrioventricular conduction. Electrophysiological study revealed a total of three focal AT in right atrium with the origin of the basal right atrial appendage (AT1), coronary sinus ostium (AT2), and low lateral right atrium (AT3), respectively. Endocardial bipolar voltage mapping showed low voltage area in the limited area, partially overlapping with the focus of AT3. We finally terminated AT2 targeting an early fractionated potential and AT3 at early activation site with a support of flexibly-bended deflectable sheath while accidentally eliminating AT3 with the bumping of a catheter. With the additional applications, we completely eliminated all AT. AT were never provoked by any inductions with isoproterenol infusion. . PMID- 30279818 TI - Cardiac hydatid cyst of the right ventricle: Severe localization. AB - A 24-year-old male was admitted for syncope and epigastric pain and fever. Biological examination showed leukocytosis and marked eosinophilia, the brain computed tomography (CT) was normal. The echocardiography revealed a voluminous mass in the free wall of the right ventricle compressing the right cavities without communication confirmed with thoracic CT. Hydatid serology was positive. Early and urgent surgery was decided. The postoperative period was uneventful and the patient was discharged home on albendazole. Hydatid cyst is an endemic parasitic infection in cattle-breading countries, and migration has played a significant role to expand this infection worldwide. Cardiac hydatidosis is rare (0.5-2%) in comparison with hydatidosis of the liver (65%) and lung (25%). The right ventricle location is even rarer, 10% versus 60% for the left ventricle, and can cause fatal complications such as anaphylactic shock, dissemination, and pulmonary embolism. . PMID- 30279819 TI - Untreated cardiac sarcoidosis with active inflammation: Severe left ventricular dysfunction and ventricular wall thinning in three years. AB - A 74-year-old female was admitted for the treatment of complete atrioventricular block. Echocardiography showed thickening of interventricular septum and a slight thinning in the basal region with normal left ventricular (LV) function. She was clinically diagnosed with cardiac sarcoidosis accompanied by active inflammation from the findings of blood test, nuclear scanning, and magnetic resonance imaging. After pacemaker implantation, we recommended corticosteroid therapy, which she refused for the fear of side effects. Three years later, she was re admitted to our hospital due to heart failure. Echocardiography showed severe LV systolic dysfunction and dilatation with wall thinning. Even though we started corticosteroid therapy and continued it for one year, LV function was not improved. In patients with cardiac sarcoidosis accompanied by active inflammation, LV dysfunction, and dilatation may rapidly progress. Early diagnosis and treatment with corticosteroid may be important to preserve cardiac function. . PMID- 30279820 TI - Successful treatment of a massive pulmonary embolism using rivaroxaban in a patient with antithrombin III deficiency. AB - We report a case of acute massive pulmonary embolism in a patient with antithrombin III deficiency. The patient was treated with rivaroxaban. The patient responded well to the therapy, and contrast-enhanced computed tomography showed nearly complete disappearance of the pulmonary embolism. Patients with low antithrombin III activity may have resistance to heparin therapy, leading to insufficient anticoagulation during the acute phase of thromboembolism. This case suggests that direct oral anticoagulants, such as rivaroxaban, may be effective first-line agents for treating venous thromboembolism in patients with antithrombin III deficiency. . PMID- 30279821 TI - Late perforation of a passively fixated pacemaker lead through the right ventricle. A report and review of literature. AB - Lead perforation is one of the serious complications associated with cardiac pacemakers and implantable cardiac defibrillators. Late perforations - occurring more than one month after placement - are exceedingly rare and are usually more associated with actively fixed leads rather than passively fixed tined leads. We present a case of blunt ended tined lead perforation after 4 months of implantation managed by a two-step hybrid minimally invasive approach consisting of mini-thoracotomy and lead tip transection, followed by trans-venous lead extraction. . PMID- 30279822 TI - Acute right to left shunt-Combination of tricuspid valve endocarditis, Chiari network, and ostium secundum atrial septal defect. AB - A 72-year-old Tongan female was admitted to our facility with dyspnea and refractory hypoxia. She became febrile and blood cultures were positive for Enterococcus faecalis. Transesophageal echocardiography was performed showing two large vegetations on the tricuspid valve causing severe regurgitation. The tricuspid regurgitant jet with the assistance of a large Chiari network was being directed across an ostium secundum atrial septal defect. This clinical scenario represented an unusual cause of acute right to left shunt explaining the patient's refractory hypoxia. . PMID- 30279823 TI - Out-of-hospital cardiac arrest related to coronary arterial spasm in three elderly patients with no obstructive coronary artery disease. AB - Coronary spastic angina (CSA) is relatively more common in young people than in elderly people. Here, we present three cases of elderly male patients who experienced out-of-hospital cardiac arrest (OHCA) likely due to coronary spasm induced ventricular fibrillation (Vf) from 2013 to 2016. After defibrillation, emergency coronary arteriography demonstrated severe coronary vasospasm that resolved following intracoronary infusion of nitroglycerin in the right coronary arteries in all three patients, with no organic obstructive lesion in the coronary arteries after nitroglycerin infusion. Case 1 was a 74-year-old patient with a past history of unstable angina and no organic obstructive lesion on coronary arteriography. He was administered oral amlodipine, isosorbide mononitrate, and nicorandil. He survived an OHCA and underwent implantable cardioverter defibrillator (ICD) implantation on day 57. Case 2 was a 71-year-old patient without prior CSA, who suddenly lost consciousness during a break after tennis. Vf was reversed to sinus rhythm by defibrillation in the ambulance. He died of multi-organ failure on day 7. Case 3 was a 66-year-old patient diagnosed with multi-vessel CSA by coronary arteriography with acetylcholine provocation test. He survived an OHCA associated with inferior acute myocardial infarction, rejected ICD implantation, and has not had a chest pain attack or syncope since discharge. . PMID- 30279824 TI - Angle-tipped guidewire-induced vascular perforation at branch of superior thoracic artery during sheath insertion: Case report. AB - An 84-year-old woman was admitted to our hospital because of congestive heart failure, rapid atrial fibrillation, and ischemic heart disease. Percutaneous coronary intervention (PCI) via the left radial artery was performed, and a stent was deployed successfully into left anterior descending coronary artery (LAD). She got into shock state one hour after PCI. Chest X-ray and computed tomography scan revealed increase of soft tissue around the left axilla and implied the existence of hematoma. Hemoglobin level decreased from 13.3 g/dL to 8.2 g/dL and hemorrhagic shock was suspected. Angiography of the left axillary artery demonstrated contrast extravasation, and selective angiography using a micro catheter identified bleeding from a branch of the superior thoracic artery. Hemostasis was performed successfully by embolization using a gelatin sponge, and improvement of the general condition was obtained. Aberration of 0.025-in. angle tipped guidewire was considered to induce arterial perforation during sheath insertion. . PMID- 30279825 TI - Thrombolytic treatment for acute prosthetic valve thrombosis: Is it better than surgery? AB - Prosthetic valve thrombosis (PVT) is a rare but often lethal complication of valve replacement. Despite advances in surgical techniques, surgical mortality remains high and emergent cardiac surgery is not widely available. Herein, we present the case of an acute PVT successfully treated with thrombolytic therapy. A 48-year-old female presented to the emergency department with acute onset of shortness of breath. Her medical history was remarkable for mitral valve replacement at the age of 42 years. Her symptoms began 4 h before, when she suddenly presented severe resting dyspnea. At arrival she showed pulmonary edema and hemodynamic instability. Echocardiography showed a prosthetic mitral valve stuck in a semi-closed position with a gradient of 39 mm Hg. Treatment was started with alteplase and the patient presented marked clinical improvement in subsequent hours. Recent evidence suggests that thrombolysis could be elected as the first choice of treatment in patients with left-side PVT because of the effectiveness, safety profile, availability, and low cost. This case illustrates the importance of prompt diagnosis and treatment and proposes thrombolytic therapy for PVT as an option at least as efficient as and far more accessible than surgery. . PMID- 30279826 TI - Percutaneous closure of an iatrogenic ventricular septal defect following transcatheter aortic valve implantation. AB - Transcatheter aortic valve implantation (TAVI) has been increasingly used in symptomatic patients with severe aortic stenosis who are at high risk for conventional open heart surgery. However, it might be associated with serious complications. We report a case with an iatrogenic ventricular septal defect as a rare complication following TAVI procedure. . PMID- 30279827 TI - Metastatic obliterating mass of right ventricular cavity: A report of case and echocardiographic features. AB - We present the case of a 63-year-old man with a history of non-small cell lung carcinoma (NSCLC) and systemic chemotherapy who suffered from progressive shortness of breath and peripheral edema. Transthoracic echocardiography showed a huge non-homogenous mass nearly completely filling the dilated right ventricle. The border of mass was not differentiable from the right ventricular myocardium. The findings of echocardiographic study were highly suggestive for cardiac metastasis. Computed tomography and positron emission computed tomography confirmed the presumed diagnosis. Lung cancer is one of the most common primary tumors of cardiac metastasis and NSCLC accounts for about 85% of all lung cancers. Lymphatic spread or direct invasion usually involves the pericardium or epicardium. However, metastasis to the myocardium and endocardium is extremely rare. The huge size, location, direct invasion to myocardium and echocardiographic features of this cardiac mass have made it a unique case for presentation. . PMID- 30279828 TI - Acute ischemic stroke what is hidden behind? AB - Acute aortic dissection (AAD) is a rare and potentially fatal disease. The classic presentation is sudden and severe pain in the chest, back, or abdomen, described as tearing or ripping pain radiating to the interscapular region. Cerebral ischemic complications occur in 18-30% of aortic dissections and patients may present to the emergency department (ED) with isolated focal neurology and no chest pain. In AAD patients, presenting with stroke and subsequently thrombolized, a 71% mortality rate has been reported in patients receiving recombinant tissue plasminogen activator (r-TPA). We present a case of a 58-year-old male patient that presented to ED with sudden onset of headache and left-sided hemiparesis, computed tomography (CT) demonstrated an ischemic stroke of the right middle cerebral artery. When the question of whether to start r-TPA or mechanical thrombectomy was discussed, a cardiac point-of-care ultrasound was performed in ED and showed a type A aortic dissection; immediately a CT aortic angiogram was performed and confirmed the diagnosis. The patient was taken to theater and had a favorable outcome. . PMID- 30279829 TI - Mitochondrial deformity confined to a single cardiomyocyte in human endomyocardial biopsy specimens: Report of 4 cases. AB - During electron microscopic examination of 156 consecutive human endomyocardial biopsy specimens, we found marked mitochondrial deformity within a single cardiomyocyte in each of 4 specimens. The deformed mitochondria were unevenly distributed, but the deformities were confined to the one cardiomyocyte. Those affected cardiomyocytes were accompanied by nonspecific degenerative changes such as nuclear hypertrophy and/or rarefaction of the myofibrils. Mitochondria in all other cells within the specimens appeared normal. Such an abnormality has never been reported to date. Each of the four cases was diagnosed with a different ailment: post-myocarditis, dilated cardiomyopathy, amyloidosis, and tachycardia induced heart failure. However, all four cases were accompanied by left ventricular systolic dysfunction at biopsy. The very limited mitochondrial deformation may thus reflect a type of degenerative change that accompanies heart failure. . PMID- 30279830 TI - Acute compartment syndrome: A rare but important complication of transradial cardiac catheterization. AB - The transradial approach has become the gold-standard for coronary angiography. It is better tolerated by patients, associated with less bleeding, earlier post procedure mobilization, and reduced mortality in patients with myocardial infarction. Given the hand's dual arterial supply and extensive collateral circulation, the risk of serious functional injury after radial catheterization is essentially reduced to zero. However, even a small amount of bleeding in the volar compartment can lead to compartment syndrome (CS) and permanent neurovascular injury. The purpose of this paper is to describe our experience with an unusual case of late-onset acute CS following transradial coronary angiography, and to summarize the available literature on this topic. . PMID- 30279831 TI - An autopsy case of aortic root rupture with thin porcelain aorta during balloon expandable transcatheter aortic valve implantation. AB - A 92-year-old woman was transferred to our institute due to drug-resistant heart failure from severe aortic stenosis. She seemed to be a candidate for transcatheter aortic valve implantation (TAVI) because of her frailty and porcelain aorta. There were no severe calcified nodules in the left-ventricular outflow tract area. Because three-dimensional computed tomography analysis showed that her basal annulus area was 419 mm2, a 26-mm SAPIEN XT (Edwards Lifesciences, Irvine, CA, USA) was selected for implantation. After deployment of the valve with 10% reduced volume, aortic root rupture occurred and her blood pressure fell due to acute cardiac tamponade. Emergent cardiac pericardial fenestration was done and drained blood was continuously returned to the circulation through percutaneous cardiopulmonary bypass. Despite strenuous efforts to save her life, she died 13 h after the event. An autopsy revealed a thin porcelain aorta and aortic root rupture with a fragile aortic wall. . PMID- 30279832 TI - Evaluation and medical therapy for coronary endothelial dysfunction induced by sirolimus-eluting stent in patient with an atherosclerotic lesion of the left main coronary artery: Case report. AB - Sirolimus-eluting stents (SES), especially those deployed at distal sites, cause more coronary vasospasm and endothelial dysfunction in the chronic phase compared to bare-metal stents (BMS). In comparison, endothelial dysfunction is less frequently induced by the Biolimus-A9 eluting stent (BES). A 75-year-old man with effort-induced angina pectoris previously underwent a total of three SES implantations in the left anterior descending coronary artery (LAD) and right coronary artery (RCA) in 2010 and 2011. He was referred to our hospital for the management of chest discomfort at rest in August 2014. We diagnosed this patient with coronary spastic angina (CSA) and coronary endothelial dysfunction (CED) induced by the SES, together with an atherosclerotic lesion in the left main coronary artery (LMCA). Adequate medication for CSA and CED and intervention for the atherosclerotic lesion contributed to improvement of vascular function and disappearance of his symptoms. . PMID- 30279833 TI - A case of upper extremity deep vein thrombosis with long-term patency using pharmaco-mechanical catheter-directed thrombolysis in the acute phase. AB - Although upper-extremity deep vein thrombosis (UEDVT) is considered rare, its prevalence appears to be increasing, and this may be related to expanding indications for catheter-based interventions. In contrast, few cases have been reported related to strenuous exercise, especially in healthy young adults with thoracic outlet syndrome (Paget-Schroetter syndrome). In contrast to lower extremity DVT, optimal treatment strategies for UEDVT have not been robustly studied. In this report, we describe a 56-year-old man with primary UEDVT presenting with left arm swelling, paresthesia, and visible collateral veins around the shoulder. Venography revealed thrombotic occlusion of the left subclavian vein. Emergent pharmaco-mechanical catheter-directed thrombolysis (PCDT) was performed, and his left subclavian vein was recanalized. A novel oral anticoagulant was initiated to prevent reclosure. The patient's symptoms subsided without major bleeding complications and at six months, he has no disability for daily activities. Follow-up ultrasonography revealed almost complete patency of the left subclavian vein, after which anticoagulation therapy was terminated. We discuss the role of PCDT in the management of primary UEDVT from the perspective of efficacy and contribution to quality of life. . PMID- 30279834 TI - Successful angioplasty with intravascular ultrasound and optical frequency domain imaging guidance for tandem intramural hematoma caused by coronary artery spasm. AB - A 39-year-old woman with no coronary risk factors was admitted due to repetitive morning chest pain. Coronary angiography revealed subtotal occlusion of the distal obtuse marginal branch that was not recanalized by intracoronary nitroglycerin administration. Intravascular ultrasound and optical frequency domain imaging showed tandem intramural hematomas in the culprit vessel. We performed cutting balloon angioplasty successfully with dual intracoronary imaging modality guidance. The 4-month follow-up angiography revealed favorable vascular healing and the provocation test induced multiple spasms, including in the culprit vessel, by intracoronary acetylcholine administration. . PMID- 30279835 TI - A remarkable case of late-onset biatrial bacterial endocarditis of the Gore HELEX septal occluder. AB - The HELEX septal occluder (W.L. Gore & Associates, Newark, DE, USA) is a popular closure device for patent foramen ovale (PFO) and secundum atrial septal defect (ASD). Composed of a versatile polymer and a wire frame, it has been used for nearly a decade. A 50-year-old African American man with a PFO repaired 5 years previously with the HELEX was admitted to our hospital with methicillin-resistant Staphylococcus aureus bacteremia. A transesophageal echocardiogram demonstrated large mobile vegetations on the left and right atrial aspects of the occluder. Cardiothoracic surgery was consulted for removal of the vegetations and device, but hesitated owing to concurrent foot osteomyelitis and concern for re-infection of a potential replacement device. The patient was persistently bacteremic, his course complicated by septic pulmonary and cerebral emboli, but eventually cleared his infection on antibiotic therapy. Seventy days since admission, the patient was discharged to a rehabilitation facility. The case illustrates that infection is possible years after PFO/ASD closure despite a theoretical neoendothelialization within 6 months of implantation. Furthermore, it accentuates the success of timely and aggressive medical treatment, thereby averting high-risk open cardiac surgery. . PMID- 30279836 TI - Dislodged stent after stent reverse controlled antegrade and retrograde subintimal tracking (CART) - Is stent reverse CART a necessary tool or an unnecessary evil? AB - We report a case of stent reverse controlled antegrade and retrograde subintimal tracking (CART) in left anterior descending artery (LAD) chronic total occlusion. Reverse CART is the method used to make a connection between the retrograde wire and the antegrade true lumen by using a balloon to dilate the antegrade space and pushing the retrograde wire into this space. We successfully crossed the septal channel from right coronary to the LAD, and proceeded to reverse CART, which was unsuccessful. After demonstrating that both the retrograde and antegrade wires were in the same subintimal space by intravascular ultrasound (IVUS), we placed the distal stent edge at the connection point of the wires and deployed the stent. We could easily wire the stent lumen with the retrograde conquest 9 g wire. Afterwards we tried to push the retrograde corsair microcatheter through the CTO and into the antegrade guiding, but unfortunately, the retrograde corsair could not pass into the antegrade guiding and was stuck just outside the antegrade guiding ostium. At this point IVUS showed that the stent had been dislodged from the LAD and pushed into the aorta just outside the left main by the retrograde corsair because the retrograde wire passed into the stent lumen through a distal side strut opening and not through the true distal end of the stent. Due to unstable hemodynamics we had to remove the retrograde system and this led to stent embolism. The case illustrates stent dislodgement after stent reverse CART and stresses the importance of using IVUS to check fully the retrograde wire path before pushing the corsair. We discuss the role of stent reverse CART in the contemporary reverse CART era and conclude that it should be relegated to the very last resort after trying transit balloon technique. We conclude that stent reverse CART is mostly an unnecessary evil. . PMID- 30279837 TI - A case of aortic valve laceration after balloon aortic valvuloplasty with morphological features. AB - A 71-year-old man suffered from congestive heart failure due to severe aortic stenosis. We performed balloon aortic valvuloplasty (BAV) as a bridge to transcatheter aortic valve replacement using transesophageal echocardiogram (TEE) by the retrograde approach. Balloon dilatation was carefully performed using an 18 mm balloon. After balloon dilation, TEE showed right coronary cusp (RCC) laceration and severe aortic regurgitation. We discontinued the procedure despite the incomplete result. Aortic valve laceration is a rare complication considered to be mainly caused by the use of large balloon or by balloon slipping. In the present case, TEE showed that the commissure of RCC fused strongly with both the other cusps by thick calcification, and the center of RCC had a spotty low echoic area with soft tissue. The force of the balloon dilatation concentrated to soft tissue area and lacerated the center of RCC. We verified the finding in the operative specimen. When performing BAV, we should pay attention to the morphology of the aortic valve using TEE to avoid aortic valve laceration as a fatal complication. . PMID- 30279838 TI - Transcatheter aortic valve implantation in a patient with aplastic anemia. AB - Aplastic anemia is a syndrome involving pancytopenia caused by bone marrow insufficiency. Pancytopenia increases the surgical risk of bleeding and infection. Here, we report a successful transcatheter aortic valve implantation (TAVI) in a patient with aplastic anemia. The patient was a 76-year-old woman who was admitted to our hospital with syncope. Laboratory testing showed pancytopenia, and echocardiography revealed severe aortic valve stenosis. Although the log.EuroSCORE and STS Score were not overly high, because of the presence of pancytopenia, surgical aortic valve replacement was considered too high risk, making her a candidate for TAVI. In this case, the patient's pancytopenia was so severe that even TAVI without preparation was considered high risk. In light of this, we carried out a two-day preoperative administration of granulocyte colony-stimulating factor and transfused packed red blood cells and platelet concentrates. TAVI was performed via the left femoral artery using the cut-down procedure under general anesthesia. The postoperative course was uneventful, and she was discharged on the sixth postoperative day. With adequate preoperative preparation, TAVI may be performed safely in high-risk patients with hematologic disorders. . PMID- 30279839 TI - Progressive spontaneous coronary artery dissection secondary to fibromuscular dysplasia requiring mechanical circulatory support. AB - Spontaneous coronary artery dissection (SCAD) usually appears as an acute coronary syndrome with good prognosis. We present the case of a 39-year-old woman with progressive SCAD secondary to fibromuscular dysplasia with catastrophic course. The patient required several mechanical circulatory support systems including a left ventricular assist device (CentriMag(r), Thoratec, Pleasanton, CA, USA) as bridge to recovery. . PMID- 30279840 TI - Incorrect Holter-ECG analysis caused by the pacemaker delivering small high frequency currents for thoracic impedance measurement. AB - In an 86-year-old woman who had been treated for sick sinus syndrome, the small high-frequency current delivered by pacemaker in order to measure the minutes ventilation for utilizing the rate-response mode was transiently over-sensed on the Holter electrocardiogram. Although her pacing system was working appropriately, the numbers of the paced beats on the automatic Holter analysis were undercounted (from >60% to <5%) during the over-sensing periods because these currents were recognized as multiple pacing spikes. Physicians need to pay attention to such multiple pacing spike markers, because these can be a cause of unreliable results of the Holter analysis. . PMID- 30279841 TI - Dog-bone inflation to salvage and redeploy a deformed, dislodged expandable stent in the external iliac artery. AB - A 64-year-old man with a history of right external iliac artery stenosis after stenting with a self-expandable stent was admitted for repetitive in-stent restenosis (ISR). To treat ISR, we selected a balloon expandable stent (BES) that was prepared with negative suction before being inserted into the sheath. BES dislodged when the stent balloon was incompletely inflated and was simultaneously deformed in a funnel shape. When BES was retrieved using a short noncompliant balloon, it dislodged again because of an imbalanced proximal inflation of the balloon. We finally retrieved BES using a long noncompliant balloon and deployed it with dog-bone inflation without any additional devices. . PMID- 30279842 TI - Three-year follow-up optical coherence tomography of under-expanded drug-eluting stent in-stent restenosis treated with ABSORB bioresorbable vascular scaffold following ultra-high pressure pre-dilatation. AB - The management of in-stent restenosis continues to be a common challenge in modern interventional cardiology. Drug-eluting stents have emerged to be an effective treatment following bare-metal stent in-stent restenosis as compared with drug-coated balloon angioplasty and repeat bare-metal stenting. The addition of another metallic layer is however undesirable and may limit further treatment options. In the last few years, everolimus-eluting bioresorbable vascular scaffolds have become available in treating native coronary artery disease with complete hydrolysis into water and carbon dioxide within 3-5 years. To exploit this property, we successfully used it to manage a case of drug-eluting stent in stent restenosis from a previously under-expanded stent as demonstrated in this case. Small registry series have also recently been published supporting favorable outcomes with this approach. To the best of our knowledge, this case has the longest optical coherence tomography follow-up beyond 3 years. . PMID- 30279843 TI - Superior vena cava syndrome complicated with acute pulmonary thromboembolism in a patient with lung cancer. AB - Thrombosis involving the subclavian vein and superior vena cava is relatively common, especially in cancer patients. Edema of the arms and head is a well-known clinical consequence of this thrombosis. The intrinsic risk of pulmonary embolism has not been reported previously. Herein, we describe the case of a 63-year-old male patient with extensive stage small cell lung cancer who developed superior vena cava syndrome. Pulmonary thromboembolism was complicated after receiving systemic chemotherapy and localized radiotherapy. . PMID- 30279844 TI - Support with a twist: New approaches in CTOs and complex lesions. AB - One-third of patients undergoing coronary angiography have coronary chronic total occlusions (CTOs) with the incidence increasing with age. Successful recanalization of a CTO is associated with a reduction in the future need for coronary artery bypass graft surgery (CABG), improvement in left ventricular function, and angina status as well as long-term survival. Success rates for treating CTOs with conventional techniques have remained unchanged over time averaging 65%-70% in experienced hands, well below the success rates for non occlusive coronary lesions. The antegrade approach is utilized in standard balloon angioplasty. Modification of this technique has been used with an anchoring balloon to more successfully open up CTOs. We describe a new device that in addition to allowing increased support, also centers one in the lumen for both coronary and peripheral intervention. . PMID- 30279845 TI - Percutaneous pulmonary debanding for an infant complicated by spontaneously closing muscular ventricular septal defect: A case report and in vitro study. AB - Pulmonary artery banding (PAB) is a standard operation for various congenital heart defects complicated by pulmonary hypertension (PH) and judged unsuitable for primary intracardiac repair. We report successful percutaneous pulmonary artery debanding in a baby complicated by muscular ventricular septal defect (VSD), that was initially large and multiple, but closed spontaneously later. The 5-month-old boy was referred to our hospital on day 3, diagnosed as having aortic coarctation (CoA), with multiple muscular VSDs and severe PH. On day 6, he underwent CoA repair and PAB using expanded polytetrafluoroethylene (ePTFE), while the muscular VSDs were left open. We planned percutaneous pulmonary debanding at the age of 5 months, as the muscular VSDs had become small. After dilation with a Mustang(r) (Boston Scientific, Marlborough, Massachusetts, United State) balloon (12 mm diameter) there was a persistent waist indicating a residual narrowing. Use of an extra-high pressure balloon, Conquest(r) (Medicon, Osaka, Japan) balloon of the same size, completely eliminated the waist. In in vitro experiments, the Mustang(r) partially tore the ePTFE, while a Conquest(r) of the same diameter completely opened the band. The mechanism of debanding was tearing of the ePTFE by the knot of the suture thread. Percutaneous pulmonary debanding to avoid unnecessary surgery is feasible in such a patient if the VSD becomes small. . PMID- 30279846 TI - Clinical efficacy of a stent-in-stent procedure for stent fracture in a narrowing anastomosis of femoral-popliteal bypass represented repetitive acute limb ischemia. AB - A 72-year-old male with sudden onset pain and coldness in his left lower limb was referred to our hospital. An emergency angiography of the lower limbs demonstrated the cause of acute limb ischemia as a subsequent acute thromboembolism at the site of a narrowing anastomosis of femoral-popliteal bypass (FPB). In particular, the site of the narrowing anastomosis had already been fixed using a nitinol stent 4 years previously. We confirmed that the severe stent fracture resulted from misalignment. After local lysis therapy, we decided to deploy another nitinol stent to in-stent restenosis (ISR) lesion of the stent fracture. Final angiography confirmed full patency in FPB without flow delay. Additionally, to maintain the patency of arterial flow, we prescribed aspirin and warfarin. After 2 years of operation, his follow-up ankle-brachial pressure index on the left side remained 0.86 and no ischemic leg pain was observed to date. Stent-in-stent procedure using another nitinol stent for ISR treatment for the narrowing anastomosis in FPB indicated feasible and effective results. . PMID- 30279847 TI - Retrograde parallel wire technique using a dual lumen catheter can be useful for percutaneous coronary intervention with chronic total occlusion. AB - The patient was a 61-year-old male with chronic total occlusion (CTO) of the right coronary artery (RCA). We performed percutaneous coronary intervention (PCI) to RCA-CTO with the bidirectional approach via the left anterior descending artery. In retrograde approach, the first wire entered the false lumen at the segment of severe stenosis of the CTO distal site. We performed parallel wire technique using a dual lumen catheter to avoid branch loss and succeeded to get the proximal true lumen through the second wire. When the first wire enters the false lumen, continued advancement of this wire easily should be avoided as it can collapse the true lumen and make reentry difficult. On top of that, in retrograde approach, it is difficult to perform parallel wire technique without using a dual lumen catheter. This case reveals that retrograde parallel wire technique using a dual lumen catheter is an extremely effective strategy to treat CTO. . PMID- 30279848 TI - Transcatheter bicuspid aortic valve replacement in Turner syndrome: A unique experience of interventional cardiologist. AB - A 69-year-old short-statured Turner syndrome (TS) patient with a history of poliomyelitis in childhood and moderate bicuspid aortic stenosis (BAS) reported worsening dyspnea and fatigue over six months. A repeat transthoracic echocardiogram revealed progression to severe aortic stenosis with dilated ascending aorta (AA). As part of the work-up for aortic valve replacement, the patient underwent cardiac catheterization, which revealed a severely calcified AV with an area of 0.5 sq. cm and a mean gradient of 37 mmHg. On coronary angiography, there was 70% stenosis of the proximal left anterior descending artery (LAD). Due to poor rehabilitation potential, she was deemed high-risk for surgical aortic valve replacement. A recommendation for transcatheter aortic valve replacement (TAVR) with stenting of the proximal LAD was made. Dilated AA was managed conservatively with serial noninvasive imaging. The patient underwent TAVR with Edwards-Sapien valve (23 mm S3) and stenting of proximal LAD. The procedure was successful without complications. To our knowledge, our patient is the first case of TAVR in BAS with aortopathy in TS. . PMID- 30279849 TI - Formation of a left atrial thrombus during percutaneous mitral valve edge-to-edge repair induced by acute reduction of mitral regurgitation. AB - Percutaneous mitral valve repair (PMVR) using the MitraClip system (Abbott, Abbott Park, IL, USA) is an innovative method allowing treatment of mitral regurgitation (MR) for patients that are not accessible by conventional operation. Thrombogenicity in the left atrium (LA) in general is increased in the presence of atrial fibrillation and mitral valve disease. We observed in a patient who underwent PMVR an acute change in thrombogenicity in the LA with thrombus formation in the left atrial appendix (LAA) immediately after clip placement. Thrombus formation occurred under verified therapeutic anticoagulation using unfractionated heparin. To our knowledge this is the first patient with documented acute and solid intra-interventional thrombus formation. The observation implies that acute reduction of mitral valve regurgitation and changes in hemodynamics within the LA enhances the risk of thrombus formation. . PMID- 30279850 TI - Conservatively treated coronary malperfusion associated with acute type A dissection before aortic root replacement. AB - Coronary malperfusion associated with aortic dissection usually requires aggressive surgical treatment or catheter revascularization. Here, we report a case of conservatively treated coronary malperfusion associated with acute type A dissection before aortic root replacement. An 81-year-old woman was rushed to our hospital in a state of circulatory shock after developing chest pain. She was severely hypotensive on admission, and the electrocardiogram (ECG) revealed anterior and lateral ST elevation. However, the initial fluid resuscitation increased her blood pressure to a normal level, and the ischemic ECG changes disappeared in about 20 min. ECG-gated cardiac multidetector computed tomography showed a type A aortic dissection complicated with left main trunk dissection. A primary entry tear was located 5 mm below the left coronary ostium. The patient successfully underwent composite graft replacement of the aortic root in a stable hemodynamic condition. . PMID- 30279851 TI - An enlarging pacemaker pocket: A case report of a plasmablastic lymphoma arising as a primary tumor around a cardiac pacemaker and systematic literature review of various malignancies arising at the pacemaker pocket. AB - To date, there have been limited reports of oncogenesis occurring within pacemaker pockets. We report the case of a 100-year-old male who presented to the emergency department complaining of expansion of his pacemaker pocket over the period of 8 days. Dissection of the pacemaker pocket and pathological analysis of tissue samples revealed plasmablastic lymphoma, a subset of diffuse large B-cell lymphoma, commonly seen in immunocompromised elderly patients. This is the first known reported case of plasmablastic lymphoma occurring within a pacemaker pocket. . PMID- 30279852 TI - The effect of pannus and weight gain in mitral stenosis after mitral ring annuloplasty. AB - Pannus formation is a known complication of valve replacement surgery. However, few cases describe pannus formation in the mitral position, and they are mostly associated with prosthetic valves rather than only annuloplasty. We describe the case of a 62-year-old woman who first underwent reductive annuloplasty using a Carpentier-Edwards 28 mm ring prosthesis in 2009 that performed well on regular follow-up for 5 years. In 2014, the patient presented with significant weight gain, shortness of breath (New York Heart Association functional class III) and signs of severe mitral stenosis. Echocardiography demonstrated the formation of a pannus and increased pressure gradients. Removal of the ring prosthesis and pannus-like fibrotic tissue was performed. The native valve was left in place as it had supple leaflets and performed well once properly debrided. The patient remained well throughout a 24-month follow-up. . PMID- 30279853 TI - Acute myocardial infarction in dextrocardia - A diagnostic and therapeutic challenge. Can dextrocardia be a risk factor? AB - Acute myocardial infarction in dextrocardia may present several challenges either in electrocardiographic diagnosis or coronary intervention or both, due to abnormal location of the heart, mirror images o the aorta and its branches, and abnormal coronary origin and orientation. Also, dextrocardia as a risk factor for coronary artery disease is less well established. We report the case of a young patient with dextrocardia and situs inversus without any risk factor who presented with acute extensive anterior wall myocardial infarction diagnosed after lead reversal and who successfully underwent coronary intervention using "double inversion technique". . PMID- 30279854 TI - Successful combined intravenous and subcutaneous immunoglobulin treatment for intractable protein-losing enteropathy in a patient long after Fontan-type operation. AB - A 20-year-old patient, who had double outlet right ventricle, mitral atresia, pulmonary atresia, and bilateral superior vena cava and underwent successful lateral tunnel total cavo-pulmonary connection at 6 years old, presented with frequent watery diarrhea, general malaise, and tetany. He was known to have intractable protein-losing enteropathy (PLE) from 7 years of age that was resistant to various treatments. To keep hemodynamics stable, he required intravenous albumin infusion every day. Fontan fenestration partially improved his condition and allowed to stop albumin infusion, however still he showed muddy stool and cachexia with low serum albumin <20 g/L and immunoglobulin <3 g/L. Because of serious risk of infection, we placed him on regular subcutaneous immunoglobulin supplementation with rescue intravenous immunoglobulin that improved his PLE within a month and allowed him to be discharged. This case illustrates that immunoglobulin supplementation can be one of the choices of treatment for intractable PLE. . PMID- 30279855 TI - Aortic coarctation endarteritis: The importance of a systematic echocardiographic study. AB - Aortic coarctation determines a favorable anatomical condition for the development of endocarditis-endarteritis due to the presence of an alteration in blood flow dynamics that favors the appearance of endothelial damage and the adhesion of microorganisms. At present, endarteritis of aortic coarctation is a rare entity due to early detection and surgical treatment of patient carriers of aortic coarctation. We present a case of a patient affected with a previously unknown aortic coarctation, who developed infective endarteritis with secondary formation of mycotic aneurysm. The echocardiography techniques proved determinant in establishing the diagnosis of aortic coarctation, as well as the associated infectious complications. . PMID- 30279856 TI - Narrowing of the QRS complex, elimination of late gadolinium enhancement and remarkable reverse remodeling achieved by optimal medical treatment in non ischemic dilated cardiomyopathy. AB - A 67-year-old woman presented with exertional dyspnea. An electrocardiogram showed complete left bundle branch block. Cardiac magnetic resonance imaging revealed left ventricular (LV) dilatation with reduced ejection fraction, no evidence of myocardial ischemia and late gadolinium enhancement (LGE) in the inferior LV wall. She was diagnosed with decompensated heart failure (HF) secondary to non-ischemic dilated cardiomyopathy. Narrowing of the QRS complex, disappearance of LGE, and remarkable LV reverse remodeling along with improvement in HF symptoms were achieved by combination therapy with angiotensin II receptor blocker, beta-blocker, and mineralocorticoid receptor antagonist. This case highlights the role of triple-blockade therapy in the treatment of HF. . PMID- 30279857 TI - A unique case of ST-elevation myocardial infarction related to very late stent thrombosis. AB - A 67-year-old man was transferred to our hospital because of anterior ST elevation myocardial infarction (STEMI). He had a history of a sirolimus-eluting stent implantation from the left main to the left anterior descending coronary artery (LAD) 9 years before and had undergone laparoscopic prostatectomy 8 days before in the setting of discontinuation of dual antiplatelet therapy. Emergent coronary angiography showed total occlusion in the distal LAD that was successfully treated by aspiration alone. Optical coherence tomography (OCT) showed no vulnerable lesion from the occluded lesion to the proximal LAD. OCT demonstrated that the thrombus attached to floating struts at the left main bifurcation and non-apposed struts at the left coronary ostium partly protruding to aorta, while the other struts were covered and well-apposed. Based on OCT findings, this case of STEMI was thought to be caused by distal embolism of a thrombus that formed at the stent site before it evolved into total occlusion. . PMID- 30279858 TI - Late complications of an atrial septal occluder provoked by anticoagulant therapy. AB - Late complications of an atrial septal occluder device (ASO) are rare but may be serious. We report a case with extensive hemopericardium five years after ASO implantation most likely triggered by anticoagulant therapy. Although not surgically confirmed, indirect clues for erosion of the atrial wall by the device were the exclusion of other etiologies, lack of recurrence after pericardial drainage and withdrawal of anticoagulants. In addition, multimodality imaging using echocardiography, computed tomography, and cardiac magnetic resonance imaging were helpful to elucidate this unusual cause. Initiation of anticoagulant treatment in patients with an ASO should be carefully balanced and may warrant more frequent echocardiographic follow-up. . PMID- 30279859 TI - Catheter-induced aortocoronary dissection at the ostium of anomalous left coronary artery during percutaneous coronary intervention for acute inferior myocardial infarction. AB - We report a case of catheter-induced aortocoronary dissection at the ostium of anomalous left coronary artery (LCA) during percutaneous coronary intervention (PCI) for acute inferior myocardial infarction (MI). Urgent coronary angiography revealed the culprit lesion of MI was the proximal segment of the right coronary artery (RCA). The anomalous LCA arose from the right sinus of Valsalva the same as the RCA. Catheter-induced aortocoronary dissection at the ostium of RCA was extended to the ostium of anomalous LCA by contrast injection. The patient fell into hemodynamic collapse due to acute occlusion of the anomalous LCA. The patient underwent successful bailout stenting at the ostium of anomalous LCA under percutaneous cardiopulmonary support (PCPS). He was weaned from PCPS system five days after PCI and was discharged. This is the first report about bailout procedure for catheter-induced aortocoronary dissection at the ostium of anomalous LCA. . PMID- 30279860 TI - Nature's balancing act: Infective endocarditis of pulmonary valve with ventricular septal defect in fifth decade; a rare and unusual presentation. AB - It is unusual for a moderate-size ventricular septal defect (VSD) to remain asymptomatic and complication-free until the age of 45 years. Similarly, infective endocarditis of anatomically normal pulmonary valve is also rare. Here we report a case in which nature created a protection for VSD, i.e. right ventricular outflow tract (RVOT) obstruction, which led to a complication, i.e. pulmonary valve endocarditis. A 45-year-old sick-looking man presented in medical emergency with fever and progressively increasing breathlessness for the previous 2 weeks. He had no significant past history. The patient was febrile and on cardiovascular (CVS) examination, ejection systolic murmur in left upper parasternal region was heard, suggesting a diagnosis of infective endocarditis. Echocardiography revealed subaortic VSD of 1.2 cm size with left to right shunt. There was moderator band hypertrophy in sub-infundibular right ventricle (RVOT obstruction) creating obstruction to blood flow, thus preventing development of pulmonary artery hypertension. There were two large vegetations (4 * 3 mm) on each leaflet of pulmonary valve. High speed turbulent jet of blood generated from right ventricle obstruction was striking the pulmonary valve leaflets which led to injury and subsequent development of infective endocarditis of pulmonary valve. The patient improved on intravenous antibiotics. The plan was to give 6 weeks of antibiotics followed by surgical closure of VSD and resection of moderator band. . PMID- 30279861 TI - Treatment of hypochloremia with acetazolamide in an advanced heart failure patient and importance of monitoring urinary electrolytes. AB - Chloride was recently recognized to play an important role in the pathophysiology of heart failure (HF). Chloride manipulation, including the use of acetazolamide, may be a requisite therapeutic target in HF treatment. An 87-year-old male patient with advanced HF and hypertrophic cardiomyopathy was admitted to the hospital due to hypochloremia (94 mEq/L) and hyponatremia (134 mEq/L) under diuretic treatment with azosemide, spironolactone, and tolvaptan. On admission, HF-related signs of overhydration were lacking, but B-type natriuretic peptide was moderately elevated. The etiology of the hypochloremia/natremia state was depletion of both electrolytes based on serum analysis and spot urinary concentrations. Immediately after admission, acetazolamide (500 mg/d) was prescribed to correct the hypochloremia in parallel with cessation of the preceding administration of azosemide and spironolactone, and tapering off of the tolvaptan over 7 days. Under treatment, both serum chloride and sodium concentrations recovered to normal (108 mEq/L and 148 mEq/L, respectively), and the serum potassium concentration decreased from 3.9 mEq/L to 2.4 mEq/L. Urinary concentrations of sodium and potassium increased from 18 mEq/L to 31 mEq/L and from 19 mEq/L to 51.5 mEq/L respectively, in concordance with the changes in serum concentrations, but the chloride concentration decreased from 18 mEq/L to 12 mEq/L, opposite the changes in the serum concentration. . PMID- 30279863 TI - The novel use of retrograde CTO PCI techniques as a rescue strategy for an acute right coronary artery occlusion due to iatrogenic dissection. AB - Coronary artery dissection is a known complication of percutaneous coronary intervention (PCI). Such dissections are often treated by antegrade PCI. When antegrade PCI fails, the options become limited to conservative management or coronary artery bypass grafting (CABG). CABG comes with its own risks, and conservative management can result in a potentially larger infarct. Here we present a novel use of retrograde chronic total occlusion (CTO) PCI techniques to treat an iatrogenic, type D dissection of the right coronary artery in a young male with an acute coronary syndrome. Reentrance of the true lumen by standard antegrade approaches failed. The rescue strategy using a retrograde CTO PCI approach not only had advantages over surgery and conservative management, but also over antegrade PCI. A soft wire, designed for collaterals, was used to "surf" the dissection and reach the antegrade guiding catheter. Thus, the true lumen could be used. This novel approach provided the advantages both of preserving major side branches, which are often lost with antegrade PCI approaches, and of not unnecessarily puncturing the dissection membrane. . PMID- 30279862 TI - Unilateral cardiogenic pulmonary edema. AB - A 45-year-old man presented with fatigue for the previous two days. Because of severe hypoxemia and chest radiograph showing severe consolidation only in the right lung field, he was admitted to a near-by district hospital under the diagnosis of acute pneumonia. Since his respiratory condition rapidly deteriorated, he was transferred to our hospital. The diagnosis of unilateral cardiogenic pulmonary edema was made based upon the echocardiographic examination which showed severe mitral regurgitation secondary to chordal rupture of the posterior mitral valve leaflet (P2). After successful intensive medical treatment with diuretics and extracorporeal membrane oxygenation, mitral valve repair was performed with quadrangular resection of the posterior mitral leaflet (P2) and insertion of 28 mm Cosgrove ring. It is important to recognize acute and severe mitral regurgitation as a main cause of unilateral cardiogenic pulmonary edema. Prompt differentiation from acute pneumonia is critical to save lives of the patients. . PMID- 30279864 TI - Time course of restenosis with "black hole" on intravascular ultrasound after implantation of platinum-chromium everolimus-eluting stent: Assessment using optical frequency-domain imaging. AB - Management of in-stent restenosis (ISR) remains challenging even in the drug eluting stent era. We report the case of a Japanese female with repeated ISR after primary percutaneous coronary intervention (PCI) for acute coronary syndrome. We observed ISR tissue with "black hole" on intravascular ultrasound, which appeared to be heterogeneous tissue on optical frequency-domain imaging (OFDI). Paclitaxel-coated balloon dilatation of the ISR lesion with "black hole" was ineffective. The morphological assessment of ISR tissue using OFDI might be important to treat ISR lesions by PCI. OFDI is a novel tool to observe the difference in the in-stent tissue characteristics. . PMID- 30279865 TI - Ablate and his bundle pace. AB - Atrioventricular junction (AVJ) ablation and pacing therapy is a safe and effective method to control heart rate in patients with atrial fibrillation and rapid ventricular rates who have failed pharmacologic rate control therapies. Usually, the pacing lead of the pacemaker is located at the right ventricular apex or septum, and sometimes the patient has a cardiac resynchronization therapy device with an additional lead implanted through the coronary sinus for left ventricular pacing. We present a 72-year-old woman with permanent atrial fibrillation who developed tachycardia-induced cardiomyopathy. She underwent AVJ ablation following pacemaker implantation with a single lead located at the His bundle region resulting in significant clinical and hemodynamic improvement at follow-up. . PMID- 30279866 TI - A rare case of spontaneously dissolved calcification of the mitral annulus: Caseous calcification of the mitral annulus. AB - Caseous calcification of the mitral annulus is a rare variant of mitral annular calcification (MAC). MAC is detected using conventional echocardiography and is prevalent in the elderly. However, limited information is currently available on the transformation of MAC. We herein report a case of a sudden liquified change in MAC, which was diagnosed using echocardiography and computed tomography. . PMID- 30279867 TI - Primary cardiac MYC/BCL6 double hit non-Hodgkin lymphoma. AB - Cardiac and pericardial involvement by malignant lymphoma is a rare condition. The present case report describes a case of primary cardiac MYC/BCL6 double hit non-Hodgkin lymphoma in the pericardium, and highlights the importance of a prompt diagnosis and aggressive pharmacologic treatment of this disease. In a symptomatic patient, a minimally invasive 3 cm sub-xiphoidal incision was performed under deep sedation with spontaneous ventilation to perform a pericardial biopsy. A 5 cm * 3 cm portion of pericardium was removed from above the right ventricle, thus ameliorating the extrinsic compression on the right chambers. The patient received 6 cycles of immuno-chemotherapy (rituximab plus cyclophosphamide, vincristine, and methylprednisolone), with no complications, achieving complete remission with no symptoms. Malignancies must be excluded in every case of acute pericardial disease with imaging techniques, and lymphomas should be always considered in the differential diagnosis of cardiac tumors. Complete surgical removal of the tumor is not necessary to achieve complete remission, and minimally invasive surgical approaches are an effective tool to confirm diagnosis and allow a precise histologic characterization. . PMID- 30279869 TI - Endovascular entry closure using Amplatzer vascular plug for the aortic dissection in sub-acute phase. AB - Enlargement due to residual dissection after surgical ascending aortic replacement is technically challenging to treat. Endovascular entry closure using an Amplatzer vascular plug 2 (AVP2) in the sub-acute phase has not been reported. A 75-year-old female underwent emergent ascending aorta replacement for Stanford type A aortic dissection. Postoperative computed tomography angiography (CTA) showed a distal aortic arch diameter of 41 mm and a patent false lumen. CTA one month after the operation revealed distal aortic arch enlargement to 52 mm, which is considered high-risk for rupture. Repeat open surgery was considered but carried a high risk of perioperative complications. Therefore, we performed endovascular closure for the entry at the proximal descending aorta using an AVP2 and stent graft coverage and coil embolization for the re-entries at the bilateral iliac arteries. CTA one month after the procedure revealed that the false lumen of the aortic arch was thrombosed and that the distal aortic arch had shrunk to 38 mm, indicating the efficacy of endovascular entry closure with the AVP2 after aortic dissection. . PMID- 30279868 TI - A case of acute coronary syndrome caused by delayed coronary ischemia after transcatheter aortic valve implantation. AB - An 84-year-old female patient suffered from dyspnea due to severe aortic stenosis. Several comorbidities and her advanced age made her acceptable for transcatheter aortic valve implantation (TAVI). The TAVI procedure was performed via a femoral access and a 26-mm CoreValve prosthesis (Medtronic, Minneapolis, MN, USA) was implanted. The prosthesis was deployed at a high position because of short distance between the annulus base and coronary arteries. Aortic angiography indicated normal contrast flow into both coronary arteries. Six months later she was readmitted to our hospital because of acute coronary syndrome. Although selective intubation of coronary arteries could not be achieved because of high valve position, both coronary arteries seemed to be well contrasted. As a consequence, the second coronary angiography was undertaken because of recurring chest pains. The aortic root angiogram showed a decreased contrast flow into both coronary arteries. During the examination she deteriorated rapidly, developed cardiopulmonary arrest, and a percutaneous cardiopulmonary support and an intra aortic balloon pump needed to be inserted. She was then transferred to the operating room for aortic valve replacement. This is the first case of delayed coronary ischemia after TAVI, necessitating the removal of an implanted CoreValve and its replacement with a new prosthetic valve. . PMID- 30279870 TI - Rapid snare sliding technique: An easy approach to difficult percutaneous transmitral commissurotomy. AB - Rheumatic heart disease (RHD) is a major health hazard in most developing countries as well as sporadically in developed economies with high prevalence rates. Mitral stenosis is among the important morbid valvular conditions accounting for 25% of RHD cases. Percutaneous transmitral commissurotomy (PTMC) using Inoue balloon is the standard treatment for severe mitral stenosis with favorable Wilkins score. In certain cases it is difficult to cross mitral valve (MV) either due to dilated left atrium (LA), low septal puncture, or severe mitral valvular and subvalvular stenosis leading to prolonged procedure time or failure of PTMC procedure. We describe a case of RHD with severe mitral stenosis and dilated LA where crossing MV was difficult and successful PTMC was performed using rapid snare sliding technique to cross the MV. . PMID- 30279871 TI - Acute right ventricular failure and pulseless electrical activity arrest following auto-transfusion of blood. AB - Air embolism is a rare but potentially catastrophic complication of interventional procedures. The occurrence of acute right ventricular dysfunction during intraoperative auto-transfusion of blood, presumably related to pulmonary embolism of agitated air microbubbles and microthrombi, is less commonly recognized. We report a case of auto-transfusion complicated by acute right ventricular failure and pulseless electrical activity arrest. Auto-transfusion of recovered blood is a practical solution to reduce need for post-procedure allogenic transfusions. Although such interventions are frequently performed without complications, they do have inherent risks that should be readily acknowledged. This case clearly describes a severe complication and sequelae of auto-transfusion. . PMID- 30279872 TI - Simultaneous transcatheter aortic valve implantation and endovascular aneurysm repair in a patient with very severe aortic stenosis with abdominal aortic aneurysm. AB - The safety of non-cardiac surgery is uncertain for asymptomatic patients with very severe aortic stenosis (AS). Herein, we describe a case involving an elderly and frail patient with asymptomatic, very severe AS. The patient was considered a high-risk candidate for aortic valve replacement (AVR); thus, transcatheter aortic valve implantation (TAVI) was planned. On perioperative examination, an abdominal aortic aneurysm (AAA) was observed, which required endovascular aneurysm repair (EVAR). To reduce the risks involved with sequential procedures, TAVI and EVAR were performed simultaneously. In patients with severe AS who are high-risk candidates for AVR, TAVI can be considered as an alternative therapy before non-cardiac surgery. In addition, the combined TAVI and EVAR procedure can reduce the risks associated with the perioperative period. . PMID- 30279873 TI - Different behaviors of bioresorbable vascular scaffold in different types of calcified lesion: Insights from intravascular imaging. AB - A 55-year-old male underwent percutaneous coronary intervention (PCI) for left anterior descending artery chronic total occlusion. After lesion preparation with non-compliant (NC) balloon, two bioresorbable vascular scaffolds (2.5/28 mm, 3.0/28 mm, Absorb BVS, Abbott Vascular, Santa Clara, CA, USA) were implanted followed by 1:1 sized NC balloon post-dilatation at 20 atm. Final intravascular ultrasound (IVUS) showed acceptable BVS expansion in diffusely calcified lesions. Twenty-one months' follow-up coronary angiography revealed severe restenosis with reocclusion at the distal edge of the distal BVS. After recanalization with a 1.0 mm balloon, optical coherence tomography (OCT) was performed. Quantitative analysis comparing OCT and IVUS at the index procedure demonstrated that minimum scaffold area at follow-up became significantly smaller and with higher eccentricity, suggesting severe recoil at the lesions with thick calcium spot, whereas these changes were not observed at the lesion with relatively thin calcification. The lesions were successfully revascularized with drug-eluting stents and final OCT showed symmetric expansion of metallic stents. Our case demonstrates that different types of calcification can have an impact on BVS expansion and recoil. In calcified lesions, an optimal implantation technique is mandatory to achieve the best possible results, and characterization of calcified lesions with intravascular imaging may be helpful to decide PCI strategy with BVS. . PMID- 30279874 TI - Giant abdominal sarcoma that caused aortic rupture at the twelfth thoracic level. AB - There are no previous reports of intraabdominal sarcoma with metastasis to the thoraco-abdominal aorta causing rupture. Here we present the case of a previously healthy 50-year old male who presented to our institution with sudden, sharp back pain. Chest and abdominal computed tomography revealed aortic rupture at the twelfth thoracic level as well as a giant mass in the left upper abdomen. We performed thoracic endovascular aortic aneurysm repair. Histopathology of a biopsy taken from a rib metastasis was thought to be either differentiated liposarcoma or malignant fibrous histocytoma. The patient is currently undergoing chemotherapy. . PMID- 30279875 TI - Multiple coronary artery spasms triggering life-threatening ventricular arrhythmia associated with the radiofrequency ablation of ganglionated plexuses of the left atrium. AB - We report a case of multiple coronary spasms leading to life-threatening ventricular arrhythmia, during left atrium (LA) ablation. Coronary artery spasm is a rare complication during radiofrequency catheter ablation of atrial fibrillation (AF). Previous reports mention that autonomic imbalance leads to coronary artery spasm and ST-segment elevation in the inferior leads, during trans-septal LA catheterization and AF ablation procedures. However, there are few reports detailing the association between ablation sites and changes in the electrocardiogram. We encountered transient ST-segment elevation and refractory ventricular arrhythmia, associated with coronary artery spasm, during radiofrequency ablation of ganglionated plexuses (superior surface of left and right atrium). . PMID- 30279876 TI - A case of acute and late coronary events after blunt chest trauma: Attention to the late onset angina. AB - Mechanisms of acute myocardial infarction caused by traumatic coronary artery injury have been reported. However, late-onset coronary artery stenosis associated with trauma is less well known. We experienced a case in which acute myocardial infarction of the right coronary artery occurred at the time of blunt chest trauma (BCT) caused by a traffic accident and an increase in coronary artery stenosis in the left anterior descending artery (LAD) branch about 1 year later. A comparison of a volume-rendering image created from enhanced-contrast computed tomography at the time of trauma and coronary angiography revealed that the trauma site and the stenotic lesion in the LAD were in very close proximity, suggesting to us that traumatic coronary artery injury without flow limitation may have developed into high-grade stenosis in the LAD 1 year later. In this case we were able to demonstrate a causal relationship between BCT and delayed coronary artery stenosis. After BCT, it is necessary to be aware of the possibility of delayed coronary artery stenosis even if coronary injury is absent in the acute phase. . PMID- 30279877 TI - Ultrasonographic and radiological imaging demonstrating an anomalous origin of the left coronary artery causing acute coronary syndrome in an adolescent. AB - We report the case of a 13-year-old girl who presented with cardiac collapse secondary to compression of the left main coronary artery (LMCA) between the pulmonary artery and the ascending aorta. In the acute phase, we performed aortography, intra-vascular ultrasound (IVUS), coronary computed tomography angiography (CCTA), transthoracic echocardiography (TTE), and transesophageal echocardiography (TEE). Aortography and CCTA showed that her LMCA was located between her pulmonary artery and the ascending aorta. IVUS and TEE showed that her LMCA was narrowed owing to compression by both great vessels during systole with release of the pressure during diastole. TTE and TEE showed that the left coronary artery flow was faster in the systole than that observed in the diastole. She was initially treated at our hospital but was transferred to another hospital for an unroofing operation. This was a rare case of a patient presenting with a coronary artery anomaly causing cardiac collapse. We conclude that her LMCA stenosis secondary to compression and narrowing of the great vessels led to her cardiac collapse. . PMID- 30279878 TI - Concurrent diagnosis of infective endocarditis and acute rheumatic fever: A case report. AB - Rheumatic heart disease has been classically considered as a risk factor for infective endocarditis (IE). Although valvulitis is frequently present in patients with acute rheumatic fever (ARF), the established valve disease after initial episode of ARF is usually considered as a predisposing factor for IE. We hereby present a biopsy-proven case of IE co-diagnosed with the first episode of ARF. . PMID- 30279879 TI - Successful alcohol septal ablation in a pregnant patient with symptomatic hypertrophic obstructive cardiomyopathy. AB - Hypertrophic cardiomyopathy is a clinically heterogeneous disease with common findings of ventricular hypertrophy, left ventricular outflow tract (LVOT) obstruction, mitral regurgitation, and diastolic dysfunction. Sometimes, the condition can lead to catastrophic cardiac events. Pregnancy can pose a larger challenge, due to medication restrictions associated with pregnancy. We report a case of a 43-year-old pregnant woman presenting with symptomatic hypertrophic obstructive cardiomyopathy (HOCM). As her pregnancy progressed, her HOCM worsened both symptomatically and by objective echocardiographic data. These changes continued despite optimized medical therapy. After an in-depth discussion with both the patient and family, we proceeded with alcohol septal ablation, which was successful in both reducing her LVOT gradient and her symptoms. Her pregnancy was overall uneventful, and both she and her child are doing well more than 4 years from the date of the procedure. . PMID- 30279880 TI - Acute peri-operative coronary subclavian steal syndrome: A diagnostic and treatment challenge. AB - The coronary subclavian steal syndrome (CSSS) generally occurs during follow up after coronary surgery. The case demonstrates an immediate peri-operative CSSS followed by myocardial infarction, notwithstanding a preoperative computed tomography scan quantifying subclavian artery calcifications as non-stenosing, and a subjective patent blood flow through the transected left internal mammary artery (LIMA). Blood flow inversion in the LIMA to anterior descending artery (LAD) bypass was detected by transit time flow measurement (TTFM). Following an elective brachiocephalic bypass a complementary, emergent subclavian bypass was performed, which restored antegrade LIMA flow, as confirmed by TTFM and angiography, but the patient suffered a peri-operative myocardial infarction. Reports about elective, concomitant subclavian and coronary surgery for sub-acute CSSS, allowing diagnostic investigations, have been published; however this case demonstrates diagnostic and treatment challenges in acute CSSS and emphasizes the role of peri-operative TTFM. . PMID- 30279881 TI - The histological findings in transposition of the great artery with severe persistent pulmonary hypertension of the newborn. AB - The combination of persistent pulmonary hypertension of the newborn (PPHN) and transposition of the great arteries (TGA) has serious impacts on treatment and prognosis, often with adverse outcomes. We report the case of a male full-term newborn with TGA with intact ventricular septum and severe PPHN who died 2 h after birth; further, we examined his vascular histology. On autopsy, lung histology showed mild fibrous hypertrophy in the intima and moderate medial hypertrophy of the minimal pulmonary artery. Hypoplasia of the pulmonary artery was not detected. Pulmonary congestion was detected and pneumatization was poor. Debris was present in the alveoli. Hemosiderin deposition was detected, suggesting prenatal hemostasis or hemorrhage. Severe PPHN may have occurred because of pulmonary arterial spasm accompanying pulmonary congestion which had been in the fetal stage. A wide range of lesions can be present in the pulmonary vascular bed in TGA. The pathologies of pulmonary vascular tissues with TGA and PPHN are not uniform. . PMID- 30279882 TI - Transcatheter aortic valve implantation in a patient with severe aortic valve stenosis, colon cancer, and obstructive ileus: A case report. AB - An 82-year-old woman with symptomatic severe aortic stenosis (AS) developed an obstructive ileus caused by colon cancer. Colectomy was considered a high-risk surgery due to both the severe AS and obstructive ileus. Therefore, we planned placement of a colonic stent for the obstructive ileus. After stenting, we performed transcatheter aortic valve implantation (TAVI) instead of surgical aortic valve replacement (SAVR), because of the risk of bleeding during extracorporeal circulation and the perioperative risk of AVR (Society of Thoracic Surgery predicted risk of mortality: 7.4%). Successful colonic stenting and TAVI allowed a safer colectomy. The period from TAVI to colectomy was 12 days. TAVI could be useful for symptomatic severe AS in high-risk patients prior to non cardiac surgery, especially for malignant tumors. . PMID- 30279883 TI - A case of conservative management for left ventricular giant pseudoaneurysm without ST segment changes. AB - Left ventricular (LV) rupture after myocardial infarction (MI) occasionally results in formation of LV pseudoaneurysm (LVPA) which is prone to rupture because of its thin wall. However, cases of LVPA without ST changes including segment elevation in electrocardiogram (ECG) are rare. In this case, we describe a patient who had relatively mild symptoms and giant LVPA with no specific ECG changes following MI with a confirmed diagnosis via transthoracic echocardiography. Although surgical treatment options are often recommended, conservative therapy was adopted, following which the patient had been well medicated using antihypertensive drugs and anticoagulants. . PMID- 30279884 TI - Reversible atrioventricular block and the importance of close follow-up: Two cases of Lyme carditis. AB - Lyme carditis is an uncommon presentation of the early-disseminated phase of Lyme disease, although it is recognizable and often curable. Because of its rarity, diagnosing Lyme carditis requires a high level of suspicion, especially when young patients in certain endemic areas present with symptoms of bradycardia and/or evidence of high-degree atrioventricular (AV) block. Temporary cardiac pacing along with antibiotic therapy has been shown to aid in the management of Lyme carditis until symptoms and conduction blocks have resolved. Herein, we report two cases of Lyme carditis-induced AV block that were successfully managed and reversed with temporary cardiac pacing and antibiotics. In order to monitor for any late sequela that may arise, we also recommend close follow-up for patients treated for Lyme carditis with high-degree AV block. . PMID- 30279885 TI - Recurrent nonbacterial thrombotic endocarditis: A novel therapeutic approach. AB - We present the case of a 29-year-old male with a history of Mizuho hemolytic anemia, a rare form of unstable hemoglobinopathy, who presented with congestive heart failure secondary to recurrent valve thrombosis despite appropriate oral anticoagulation. He subsequently required mitral and aortic valve replacement. Pathologic examination revealed extensive nonbacterial thrombotic endocarditis. Due to recurrent thrombosis despite therapeutic anticoagulation, we elected to treat him with red blood cell exchange transfusions and hydroxyurea. He has remained free of symptoms for almost two years with this treatment regimen without side effects. . PMID- 30279886 TI - Limited effects of long-term enzyme replacement therapy on the cardiac conduction system in Fabry disease. AB - The long-term effects of enzyme replacement therapy (ERT) on cardiac function and the conduction system in Fabry disease are not clearly understood. We report a case of a 48-year-old man with non-classical Fabry disease treated with ERT for 11 years. He was diagnosed with Fabry disease at age 27 years based on the presence of decreased alpha-galactosidase A activity in the peripheral leukocytes and of the causal alpha-galactosidase A mutation (Val339Gln). Subsequently, peritoneal dialysis was initiated for renal failure at age 35 years. ERT was initiated at age 39 years to halt the progression of cardiac dysfunction. Electrical conduction disturbances progressed gradually to complete atrioventricular block with atrial standstill during 9 years of ERT despite the lack of progression of ventricular hypertrophy. Although he underwent permanent pacemaker implantation to prevent sudden cardiac death, the atrioventricular junctional rhythm remained, thereby lowering the ventricular pacing rate. Based on this case, we recognize that the effects of ERT are limited for inhibiting the progression of Fabry disease and especially for inhibiting arrhythmia and conduction disturbances. Early diagnosis of Fabry disease and early initiation of ERT might be the key to further improvements in this disease and its associated conditions. . PMID- 30279887 TI - A single-stage hybrid approach for the management of severely stenotic bicuspid aortic valve, ascending aortic aneurysm, and coarctation of the aorta with a literature review. AB - The combination of aortic stenosis in the context of bicuspid aortic valve, aneurysmal dilatation of the ascending aorta, and coarctation is not uncommon. This condition has conventionally been addressed either by a complex open surgical approach or by staged hybrid approach combining open surgery of the ascending aorta with subsequent endovascular stenting of the coarctation. So far, the risk of a complex open approach for the aortic valve and ascending aorta and the cumulative risk of a staged second procedure for management of the coarctation are unknown; and similarly, the risk of a complex single-staged surgical procedure as an option instead of a single-staged hybrid approach is unknown. For the first time, we present a case of a patient with bicuspid aortopathy and concomitant coarctation who was simultaneously managed with both stenting of the coarctation and subsequent surgical replacement of the aortic valve and ascending aorta in one session. This new strategy has potential to become a future standard of care with various advantages. . PMID- 30279888 TI - Effect of subcutaneous oxycodone for end-stage heart failure due to severe aortic stenosis - A case report. AB - It is difficult to manage the symptoms of patients who are dying of end-stage heart failure (HF). Opioids are sometimes required to relieve their symptoms in addition to oxygen therapy and medical management. Oxycodone is a MU receptor agonist that is known to be a safer opioid than morphine in patients with chronic kidney disease (CKD) because its metabolites have weak pharmacological activity. We treated a 99-year-old woman who had end-stage HF (secondary to severe aortic stenosis) and CKD. It was also difficult to maintain an intravenous line because of severe edema. We administered oxycodone subcutaneously and successfully alleviated her severe symptoms without severe adverse effects of opioids until a few days before her death. We report this case and discuss the possibility of using subcutaneous oxycodone as a new palliative care strategy in patients with end-stage HF. . PMID- 30279889 TI - Right coronary artery fistula with giant pseudoaneurysm presenting as intrapericardial mass. AB - Coronary artery fistulas are rare congenital anomalies usually discovered incidentally on imaging studies. Coronary artery pseudoaneurysms are unusual complications of coronary artery fistulas, which can be due to atherosclerosis, inflammatory, traumatic or iatrogenic causes. We present a case of a 55 year old female with no known atherosclerotic risk factors, history of trauma or connective tissue disease referred because of recurrent palpitations. Work ups revealed a cardiac mass with an initial assessment of pericardial cyst. A multi modality approach of two dimensional echocardiography with Doppler studies, multidetector computed tomography and coronary angiogram revealed coronary artery fistula draining into a pericardial mass. The patient underwent surgical excision of the mass and ligation of the feeding vessel. Histopathology revealed features suggestive of a pseudoaneurysm. Postoperative course was uneventful and she was discharged stable and improved. Coronary artery fistula complicated by pseudoaneurysm is a rare clinical entity especially in patients without history of trauma or other risk factors. It can have an unusual presentation which can confound the diagnosis. Multimodality imaging is essential and adjunctive in order to determine a conclusive assessment. . PMID- 30279890 TI - Left ventricular reverse remodeling after transcatheter aortic valve implantation complicated by paroxysmal complete atrioventricular block. AB - An 86-year-old man with unremarkable clinical history complaining of asthenia and dyspnea was diagnosed with low-flow low-gradient aortic stenosis [LFLG-AS; left ventricular ejection fraction (LVEF) 40% and transaortic mean gradient 37 mmHg, increasing to 52% and 55 mmHg after dobutamine infusion]. The patient underwent transcatheter aortic valve implantation (TAVI; Edwards CENTERATM 29, Irvine, CA, USA). The procedure and the following hospital stay were free from complications, with no changes on electrocardiography (ECG). Six months later, few syncopal episodes occurred. No signs of orthostatic hypotension or neurologic disorders were present. Echocardiography showed normal functioning of the prosthetic valve and recovery of LV systolic function (LVEF 55%). Baseline ECG and 24-h Holter monitoring were unremarkable. An implantable loop recorder (ILR) was implanted to verify the occurrence of paroxysmal conduction disturbances. One month later, during a syncopal episode, ILR interrogation showed a complete atrioventricular (AV) block. Therefore, a dual chamber, single lead pacemaker was implanted. We are providing the first report of complete AV block occurring months after TAVI, possibly because of reverse LV remodeling following TAVI, with ensuing relative oversizing of the prosthetic valve. This possibility should be considered in patients with syncope not otherwise explained, and previous TAVI, especially in cases of LFLG-AS. . PMID- 30279891 TI - Familial pulmonary thromboembolism with a prothrombin mutation and antithrombin resistance. AB - We describe the case of a 45-year-old man with congenital thrombophilia induced by antithrombin resistance. He had recurrent venous thrombosis without traditional risk factors or abnormal coagulation function and had a family history of venous thrombosis which included his mother, brother, and nephew. We suspected the association of hereditary antithrombin resistance, which has been reported in some cases of familial venous thromboses due to prothrombin mutations. Although prothrombin abnormality typically shows a bleeding tendency, variations of arginine at position 596 in the gene encoding prothrombin have been reported to conversely cause thrombosis. Therefore, we tested and detected antithrombin resistance in the patient's plasma. We also performed genetic analysis for his second filial generation, and found a missense mutation (c.1787G>A), resulting in a substitution of arginine for glutamine at position 596 (p.Arg596Gln) in the gene encoding prothrombin (called prothrombin Belgrade). The Gln596 substitution caused the susceptibility to thrombosis. This variation is the same as one previously reported in Serbia and India, and it is the third report in Japan. . PMID- 30279892 TI - Emergent caesarean section under mechanical circulatory support for acute severe peripartum cardiomyopathy. AB - Peripartum cardiomyopathy (PPCM) is an idiopathic left ventricular dysfunction in women who are in late pregnancy or the postpartum period. PPCM is a rare but sometimes fatal disease, and mechanical circulatory support is required if heart failure is refractory to conventional therapy. A 28-year-old woman in late pregnancy was admitted to our hospital due to congestive heart failure with cardiogenic shock. Her heart rate was 200 beats per minute (sinus tachycardia), and left ventricular ejection fraction (LVEF) was 10%. Additionally, fetal heart rate decreased to 80 beats per minute. It was extremely difficult to continue her pregnancy because of decompensated heart failure and fetal asphyxia; therefore, we delivered her baby via caesarean section after initiating mechanical circulatory support. With optimal medical therapy, including bromocriptine, we were able to remove mechanical circulatory support. Additionally, LVEF improved to 42%, and she was discharged with her baby who had no growth failure. This case highlights the safety and risk of caesarean section under mechanical circulatory support, and the effectiveness of bromocriptine. . PMID- 30279893 TI - Multiple potency of ezetimibe in a patient with macroproteinuric chronic kidney disease and statin-intolerant dyslipidemia. AB - Dyslipidemia is often complicated by chronic kidney disease (CKD). Lipid-lowering medications may be effective, in part, for inhibiting development and progression of CKD. Ezetimibe, a cholesterol absorption inhibitor, has pleiotropic actions, including anti-inflammatory and anti-oxidant effects, contributing to a decreased risk of cardiovascular diseases. A 40-year-old woman was admitted with dyslipidemia and macroproteinuria, whose samples of renal biopsy showed exudative lesions, but without glomerular basement membrane thickening or nodular lesions, in some glomeruli. Blood glycemic parameters were normal. After initiation of atorvastatin, she developed muscle pain and an increase in serum creatine kinase. Twelve months after switching to ezetimibe, serum levels of low-density lipoprotein cholesterol and triglyceride reduced from 170 mg/dL to 116 mg/dL and from 320 mg/dL to 160 mg/dL, respectively. Although serum creatinine levels remained unchanged after 12 months, urinary protein excretion and urinary liver type fatty acid binding protein were reduced. Flow-mediated dilatation also increased from 4.9% to 5.5% after 12 months, associated with a slight decrease in mean intima-media thickness in the common carotid artery from 0.722 mm to 0.718 mm. These results suggest that ezetimibe protects against renal and vascular damage in patients with CKD and statin-intolerant dyslipidemia. . PMID- 30279894 TI - Transcatheter aortic valve implantation for severe aortic stenosis in dextrocardia with situs inversus using a self-expanding aortic valve. AB - Transcatheter aortic valve implantation (TAVI) has evolved into a standard therapy for aged patients with severe aortic valve stenosis who are not candidates for surgery. However, the reports about the safety of TAVI for patients with dextrocardia situs inversus are few. An 84-year-old man with dextrocardia situs inversus underwent a TAVI for severe aortic stenosis (AS) with an aortic valve area of 0.5 cm2, and a mean pressure gradient of 46 mmHg. Preoperative computed tomography (CT) revealed an inverted (rightward) orientation of the ventricle apex as well as the great vessels. The TAVI was performed through a transfemoral approach under general anesthesia. A left and right reversed fluoroscopic image was used for the TAVI. Finally, a 26-mm CoreValve Evolut R (Medtronic, Minneapolis, MN, USA) was successfully deployed at the aortic annulus under angiographic guidance. Post-procedural transthoracic echocardiography demonstrated a well-functioning CoreValve Evolut R with a mean pressure gradient of 8 mmHg. No complications occurred during the procedure or peri-procedural period. The patient's symptoms subsequently improved from New York Heart Association class III to class I. In conclusion, a TAVI procedure was safely performed in a patient with dextrocardia situs inversus through a transfemoral approach by evaluating the anatomical details with preoperative CT. . PMID- 30279896 TI - Pseudo-vanishing lung syndrome in a patient with tricuspid valve bacterial endocarditis. AB - Infective endocarditis is a major cause of morbidity and mortality among individuals with opioid use disorder who use injection drugs. It is frequently associated with tricuspid valve endocarditis and Staphylococcus aureus bacteremia, with secondary pulmonary septic emboli. Herein, we report a unique case of pulmonary cavitation injury following pulmonary septic emboli in the setting of tricuspid valve endocarditis in an injection drug user with opioid use disorder. The pattern of cavitary lung injury mimics radiographically indistinguishable features from vanishing lung syndrome during the most advanced stage of her illness. . PMID- 30279895 TI - Leadless pacing in a patient with superior vena cava syndrome undergoing lead extraction and percutaneous angioplasty. AB - Superior vena cava (SVC) syndrome is an uncommon but serious complication associated with chronic transvenous implanted leads. In the recent past, open heart surgery combining lead extraction and epicardial implant was usually performed to reduce syndrome recurrences. We describe the case of a 78-year-old man successfully treated by percutaneous lead extraction associated with venous balloon angioplasty and reimplantation of leadless pacemaker. . PMID- 30279897 TI - Right internal jugular vein thrombosis caused by aneurysm of right-sided aortic arch. AB - A right-sided aortic arch is normally asymptomatic. We report the case of an 84 year-old man with right internal jugular vein thrombosis caused by an aneurysm in a right-sided aortic arch. The patient had undergone open repair of an abdominal aortic aneurysm and had an uneventful postoperative course. However, a routine postoperative contrast-enhanced thoracic and abdominal computed tomography scan showed right internal jugular vein thrombosis. The patient had no history of catheter insertion in the right jugular veins and had no hereditary coagulopathy. It was presumed that the cause of this thrombosis was compression of the right brachiocephalic vein by an aneurysm of the right-sided ascending aorta that was considered too small to require surgical repair. The right internal jugular vein thrombosis was successfully treated with edoxaban. . PMID- 30279898 TI - Subacute aortic regurgitation due to traumatic tear in the aortic wall. AB - A 37-year-old man presented with heart failure caused by severe aortic regurgitation (AR). He had a history of being involved in a traffic accident 3 months earlier. Imaging tests at admission detected no abnormalities in the aortic valve or aortic wall; however, the left coronary cusp prolapsed slightly on transthoracic echocardiography. He underwent aortic valve replacement because of uncontrolled heart failure and severe AR. Intraoperatively, the intima of the aortic wall just above the commissure of the left and right coronary cusps was torn to the short axial direction. Local aortic tear was the final diagnosis for the subacute AR. . PMID- 30279899 TI - Hemorrhagic shock due to branch injury of the left internal thoracic artery two days after pericardiocentesis. AB - Pericardiocentesis is a definitive strategy to remove pericardial effusion. In this report, we present a rare case of a 23-year-old man with sudden delayed hemorrhagic shock due to branch bleeding of the left internal thoracic artery (LITA) two days after undergoing pericardiocentesis. Angiography, embolization, and drainage were effective. As far as we know, this is the first report that shows delayed bleeding due to branch injury of the LITA as a possible complication after pericardiocentesis. . PMID- 30279900 TI - Pacemaker malfunction after acute myocardial infarction in a patient with wrap around left anterior descending artery supplying the right ventricular apex. AB - A 50-year-old man with a dual-chamber pacemaker was admitted to our hospital complaining of chest pain. Anterior ST segment elevation myocardial infarction (STEMI) was diagnosed. Emergency coronary angiography revealed total occlusion of the proximal left anterior descending artery (LAD), and primary percutaneous coronary intervention was performed. Angiograms showed that the LAD was wrapped around the apex of both ventricles. On day 8, ventricular fibrillation and cardiopulmonary arrest occurred due to elevation of the pacing threshold because of pacemaker malfunction. The pacemaker was upgraded to an implantable cardioverter-defibrillator and the lead was inserted into the right ventricular septum. Myocardial scintigraphy with thallium-201 and technetium-99m pyrophosphate located the infarct zone around the apex of both ventricles. We conclude that pacing failure of the right ventricular lead occurred in this case of LAD occlusion due to a LAD supplying the right ventricular apex. Clinicians should be aware of the possibility of pacemaker failure in patients presenting with anterior STEMI due to a wrap-around LAD. . PMID- 30279902 TI - Simultaneous suction debulking of lead vegetation prior to percutaneous lead extraction. AB - The infection rates of implanted cardiac devices have increased disproportionate to the dramatic increase in implantation rates, possibly related to rising patient comorbidities. Optimum strategy in cases with larger size vegetations, however, remains to be ascertained. In the absence of an effective and less invasive alternative, such patients usually undergo open thoracotomy for lead extraction. We describe the case of a 50-year-old female presenting with recurrent methicillin-resistant Staphylococcus aureus bacteremia found to have 3 cm highly mobile vegetation on the right ventricular lead of her implanted defibrillator. While being intermediate-to-low surgical risk, she underwent AngioVac-directed suction debulking (AngioDynamics, Latham, NY, USA) of the vegetation simultaneously preceding percutaneous laser lead extraction in a single session. This less invasive alternative to open thoracotomy has been described in high surgical risk patients, but its widespread role remains unexplored. . PMID- 30279901 TI - Two rare cases of congenital aortic stenosis showing a discrepancy between preoperative imaging diagnosis, intraoperative findings, and histopathological diagnosis. AB - Unicuspid aortic valve (UAV) is an extremely rare congenital heart valve abnormality while bicuspid valve (BAV) has been reported as one of the most common cardiac anomalies. With a UAV usually showing similar presentations to a BAV, such as aortic regurgitation or aortic stenosis (AS), it is challenging to differentiate them from each other in clinical settings. Despite some features shared between both valve disorders, there can be a clinical significance in distinguishing UAV from BAV for the management of patients with these heart anomalies. Herein, we describe two cases where patients with hemodynamically severe AS were diagnosed with BAV and UAV, respectively based on preoperative examinations and intraoperative findings, but subsequent pathological examinations confirmed the opposite diagnosis in both cases. . PMID- 30279903 TI - Left ventricle pseudoaneurysm: Diagnosis by a new murmur. AB - Incomplete rupture of the ventricle free wall can occur after myocardial infarction. This occurs when an organized thrombus and the pericardium seal the ventricular perforation. This can progress to the formation of a left ventricle pseudoaneurysm (LVPA). A 70-year-old male with an antero-septal ST-elevation myocardial infarction (STEMI) underwent an emergent left heart catheterization which revealed severe three-vessel disease with occluded grafts, non-amenable to re-vascularization, and an apical thrombus. As he was high-risk for repeat coronary artery bypass graft, he was medically managed. Transthoracic echocardiogram (TTE) showed a normal left ventricle ejection fraction (LVEF), apical anterior and inferior wall akinesis, moderate sized apical thrombus, and pericardial thickening. On hospital day 7, examination revealed a new 3/6 to-and fro murmur that was loudest at the apex. The patient was asymptomatic with normal vital signs. A repeat TTE revealed an apical wall rupture with flow into the pericardial cavity and absence of the apical thrombus. A LVPA was diagnosed and the patient was immediately referred for surgical repair. This case illustrates the potential for developing LVPA in STEMI patients and the importance of physical examination. If identified early a potential emergent situation in a previously asymptomatic patient can be averted, thereby preventing fatal consequences. . PMID- 30279904 TI - Atrial tachycardia originating from an incompletely isolated box lesion in a patient undergoing thoracoscopic left atrial appendectomy and surgical ablation for long-standing persistent atrial fibrillation. AB - The efficacy of pulmonary vein isolation for persistent atrial fibrillation or long-standing persistent atrial fibrillation is limited. Thoracoscopic surgical ablation was introduced as an alternative treatment, but additional catheter ablation is needed to treat postoperative atrial tachycardia in some cases. Little is known about electrophysiological characteristics or mapping techniques of recurrent tachycardia after total thoracoscopic surgical ablation and left atrial appendectomy. A 63-year-old man underwent catheter ablation of atrial tachycardia after total thoracoscopic left atrial appendectomy and surgical ablation of atrial fibrillation lasting longer than 5 years. Catheter ablation was performed using a three-dimensional mapping system. Electroanatomical mapping outside the box lesion revealed a centrifugal activation pattern with the origin located at the gap of the roofline, and further activation mapping inside the box lesion was conducted again with the reference catheter positioned at the left atrial posterior wall, which revealed localized reentrant atrial tachycardia. Atrial tachycardia was smoothly treated with activation mappings. This case indicated the utility of activation mappings separating outside the box lesions from inside the box lesions. . PMID- 30279905 TI - A case of hypertensive emergency, primary hypothyroidism and large pericardial effusion with early tamponade. AB - Thyroid hormones and the cardiovascular system are strongly intertwined with known risk of coronary disease, atrial fibrillation, and cardiomyopathy. Pericardial effusions are commonly seen in cases of severe hypothyroidism, however large to massive pericardial effusions with cardiac tamponade are exceptionally rare. We report a case of a patient presenting with hypertensive emergency and a concomitant diagnosis of primary hypothyroidism with a large pericardial effusion and early echocardiographic features of tamponade. Following pericardiocentesis, hypertension management, and thyroid replacement therapy the patient's symptoms improved with no recurrence of pericardial effusion. . PMID- 30279906 TI - The TNNI3 Arg192His mutation in a 13-year-old girl with left ventricular noncompaction. AB - Left ventricular noncompaction (LVNC) is a distinct cardiomyopathy that is morphologically characterized by a two-layered myocardium, numerous prominent trabeculations, and deep intertrabecular recesses communicating with the left ventricular cavity. We present a case report regarding the identification of a new mutation in TNNI3 in a patient with LVNC using next-generation sequencing. A 13-year-old girl who had no family history of cardiac disease was hospitalized with dyspnea after exercise and electrocardiographic abnormalities during a school screening. Based on her clinical features, she was diagnosed with LVNC. Via genetic analysis, a TNNI3 heterozygous missense variant was identified in the proband. Although mutations in TNNI3 have been reported in patients with hypertrophic cardiomyopathy and restrictive cardiomyopathy, this is the first report of a mutation in this gene in a patient with LVNC. . PMID- 30279907 TI - Leuconostoc species endocarditis in an intravenous drug user. AB - Infective endocarditis is a potentially lethal infection, which predominantly affects the atrioventricular valves. Rapid identification and management is critical to reduce morbidity and mortality in this patient population. Herein, we present a case of a 24-year-old man with Leuconostoc species infective endocarditis of the aortic valve. Disease course was complicated by several septic emboli to the brain, central retinal artery, and spleen. This case serves to remind clinicians that Leuconostoc species, which are typically not pathogenic to human species, can cause infective endocarditis in individuals with a history of intravenous drug use. . PMID- 30279908 TI - Acute cardiac tamponade secondary to ruptured pericardial cyst: Case report and literature review. AB - Pericardial cysts are a rare disorder with an incidence of about 1 in 100,000, the majority of which are benign and incidentally identified. Pericardial cyst causing cardiac tamponade is an extremely rare phenomenon. The exact incidence of cardiac tamponade secondary to pericardial cyst is unknown. To the best of our knowledge limited case reports showing this association have been published. We have summarized cases showing this association in a tabular fashion. We present a case of a 36-year-old male who presented with symptoms of shortness of breath, chest pain, and fevers found to have ruptured pericardial cyst causing cardiac tamponade. . PMID- 30279909 TI - An incomplete pacemaker lead fracture causing inappropriate pacing inhibition due to oversensing of the minute ventilation sensor pulses. AB - Cardiac pacemakers using rate response technologies represent the effectiveness of increasing the heart rate and cardiac output during exercise. Minute ventilation (MV) sensors are popular and estimate rates using transthoracic impedance by emitting very low amperage short electrical current pulses between the pacemaker lead tip and pulse generator. We present a case of an incomplete pacemaker lead fracture developing inappropriate pacing inhibition due to oversensing caused by the electrical current emitted by the MV sensor. A permanent pacemaker replacement was performed, resulting in no further abnormal findings such as inappropriate pacing inhibition. . PMID- 30279910 TI - Urgent cardiac resynchronization therapy is useful in patients with decompensated heart failure requiring inotropes and mechanical circulatory support. AB - Although cardiac resynchronization therapy (CRT) is beneficial in patients with heart failure (HF) and left ventricular dyssynchrony, its effectiveness has not been established in patients with decompensated HF on mechanical support. Here, we report two patients with decompensated HF depending on inotropes and intra aortic balloon pumping (IABP), who were rescued by urgent CRT implantations. Both patients had non-ischemic cardiomyopathy with wide QRS of left bundle brunch block. IABP could be weaned just after introducing CRT. CRT can dramatically improve hemodynamics even in severely decompensated HF, and thus could be considered when left ventricular dyssynchrony is present. . PMID- 30279911 TI - Right atrium floating thrombus and bilateral pulmonary embolism in a patient with pancreatic pseudocyst. AB - Pulmonary embolism in the context of pancreatitis is a rare condition and even fewer cases of pulmonary embolism associated with pancreatic pseudocyst and chronic pancreatitis have been reported in the literature. We present the case of a patient diagnosed with chronic pancreatitis due to alcohol ingestion complicated with pancreatic pseudocyst, with no classic thrombogenic risk factors, who developed right atrial thrombus and massive bilateral pulmonary embolism. . PMID- 30279912 TI - Dynamic left ventricular outflow tract obstruction complicated with takotsubo cardiomyopathy: The acute phase of takotsubo cardiomyopathy manifests latent left ventricular outflow tract obstruction. AB - Dynamic left ventricular (LV) outflow tract (LVOT) obstruction is sometimes complicated with takotsubo cardiomyopathy (TC). The present case involves a 70 year-old woman with chest discomfort. Seven years earlier, transthoracic echocardiography revealed LVOT obstruction due to a sigmoid-shaped septum. She underwent urgent cardiac catheterization for suspected acute coronary syndrome. She was diagnosed as having TC with LVOT obstruction. After undergoing conservative treatment, her LV function normalized and the LVOT obstruction resolved. After the LV wall motion normalized, administering an intravenous infusion of dobutamine again provoked LVOT obstruction. In this situation, the presence of TC manifested latent LVOT obstruction. . PMID- 30279913 TI - Transcatheter occlusion of complex pulmonary arteriovenous malformations in a cyanotic child. AB - This case report presents a 16-month-old boy with isolated mild cyanosis diagnosed to have complex pulmonary arteriovenous malformations. Three dimensional computed tomography with volume rendering has provided the diagnosis, enabled detailed imaging, and facilitated transcatheter device occlusion of the complex arteriovenous malformations by vascular plugs and coils. Magnetic resonance of the brain revealed associated dural arteriovenous malformation. Genetic testing showed a missense disease-causing variant in the ENG gene that encodes endoglin, and the diagnosis of hereditary hemorrhagic telangiectasia was made. . PMID- 30279914 TI - Mid-axillary pacemaker re-implantation after contralateral pocket infection in an emaciated elderly case. AB - The number of implantations of cardiac implantable electrophysiological devices (CIEDs) has increased over the past several years. However, the aging population and expansion of indications for CIEDs have led to an increase in associated infections. We experienced a case of a 99-year-old man presenting with skin erosion at the pocket site, where a 6-month-old implantable pacemaker was replaced. He was referred for pacemaker pocket infection and presented with fever accompanied by pain and swelling around pacemaker generator. We could not explant 7-year-old pacemaker leads and the patient refused to undergo either laser lead extraction or surgical removal. We planned to re-implant in the contralateral chest. However, the patient was emaciated with low body-mass-index (15.2 kg/m2), thus concerns arose about the possibility of tissue disruption and re-infection owing to thin skin and absence of sufficient subcutaneous tissue in contralateral subclavian region. Axillary placement of CIEDs has been adopted in patients with limited venous access. We applied a mid-axillary pacemaker implant procedure to this elderly and emaciated patient. Postoperative clinical course was uneventful. After discharge, no history of unexplained fever or illness was recorded. Mid axillary pacemaker pocket could be an alternative approach for re-implantation in patients with emaciated, cachexic, or limited pocket preparation. . PMID- 30279916 TI - Two adherent blood cysts in subvalvular apparatus of the mitral valve causing severe left ventricular outflow tract obstruction. AB - Blood cysts in the heart are often incidentally found during post-mortem examinations in infants, and usually do not cause clinical symptoms. They almost always regress spontaneously, and only a few cases of embolization or valvular dysfunction have been reported previously. We report a 62-year-old man who presented with chest discomfort and dyspnea on exertion for several years, and was found to have a dynamic murmur in left ventricular outflow tract (LVOT) on physical examination. His echocardiogram demonstrated two large blood cysts attached to the subvalvular apparatus of mitral valve, causing significant LVOT obstruction and mild to moderate mitral regurgitation. The cysts were surgically excised and pathology confirmed simple blood cysts. . PMID- 30279915 TI - Evaluation of repeated progression of native coronary artery stenosis by optical frequency domain imaging in a patient with essential thrombocytosis. AB - Essential thrombocytosis (ET) is a myeloproliferative disorder with abnormal proliferation of the megakaryocytes and is manifested clinically by the overproduction of dysfunctional platelets, leading to thrombus formation. Therefore, the accurate evaluation of the morphological features for coronary stenosis and initiation of appropriate treatment may be life-saving for ET patients. In this report, we describe a case of the rapid development of repeated stenosis in the native coronary artery in an ET patient, and optical frequency domain imaging confirmed the etiology of the stenoses. These findings may be helpful for consideration of etiology and therapeutic strategy for thrombotic complications in ET patients. . PMID- 30279917 TI - Promising method for management of venoarterial extracorporeal membrane oxygenation: A case of severe heart failure successfully stabilized by "high flow/vasodilation method". AB - We report the case of a 58-year-old man with dilated cardiomyopathy who was hospitalized because of worsening heart failure. As his symptoms were refractory even with the administration of inotropes, he was given peripheral venoarterial extracorporeal membrane oxygenation (VA-ECMO) upon transfer to our hospital. On admission, serum creatinine was 2.62 mg/dL and total bilirubin 10.8 mg/dL. The cannulas inserted were 16-Fr for infusion and 21-Fr for drainage. When the blood flow was increased to 2.14 L/min/m2 to improve organ dysfunction, the aortic valve became continuously close with the mean arterial pressure of 85 mmHg. Therefore, we administrated vasodilators to decrease mean arterial pressure, or left ventricular afterload, which achieved opening aortic valve continuously. After the cannula sizes were scaled up to 18Fr for infusion and 24Fr for drainage to gain further blood flow, the aortic valve opened continuously and mean pulmonary pressure decreased. Our strategy to maintain adequate flow rate of VA ECMO using vasodilator, "high-flow/vasodilation method", achieved hemodynamic stability. Additionally, the concentration of serum creatinine and total bilirubin gradually decreased to within the normal range, although the patient succumbed 58 days after transfer to our hospital. . PMID- 30279918 TI - Adult aortic coarctation presenting with refractory heart failure and pulsation below the bilateral clavicle. AB - Adult aortic coarctation is often asymptomatic and this condition can be detected because of a murmur or unexplained hypertension. Here, we report an adult case of aortic coarctaion with heart failure and a characteristic finding of pulsation below the bilateral clavicle. A 58-year-old man with refractory heart failure due to unknown reasons was referred to our hospital. Auscultation presented no murmur and high blood pressure had been treated with medicine. Interestingly, precise physical examination revealed the bilateral pulsation at the midclavicular line from the 2nd to the 5th intercostal areas. Echographic examination revealed the dilated vessel and arterial blood flow 1-2 cm in depth from the body surface at the midclavicular 2nd intercostal areas. Contrast enhanced computed tomography showed thoracic aortic coarctation and a well developed collateral circulation via the bilateral internal thoracic arteries and epigastric arteries. The cause of heart failure was diagnosed as aortic coarctation. Palliative revascularization was performed and his blood pressure was lowered. When we see the patients with refractory heart failure due to unknown reasons, pulsation below the bilateral clavicle may give us a clue to diagnose the "hidden" aortic coarctation. . PMID- 30279919 TI - Novel assessment of retrospective on-demand analysis of venous thromboembolism by dual-layer spectral-detector CT. AB - Because the prognosis of pulmonary thromboembolism (PTE) will be often poor, early diagnosis and assessing severity at the first visit is important. A 76-year old man with suspected venous thromboembolism and a contrast deficit in the pulmonary artery (PA) was revealed by contrast-enhanced computed tomography (CT) imaging by dual-layer spectral-detector CT (IQon Spectral CT(r), Philips Healthcare, Best, The Netherlands). The lung perfusion image showed decreased perfusion in the culprit lesion. The dual-energy analysis of the virtual monoenergetic imaging showed clear visualization of deep vein thrombosis (DVT). In a 64-year-old man, an IQon Spectral CT(r) revealed a small contrast deficit in the PA. However, no perfusion abnormality was detected in the lung perfusion analysis. The IQon Spectral CT(r) enables the detection of lung perfusion abnormalities in addition to PTE. The IQon Spectral CT(r) imaging may be useful for the "one-stop shop" evaluation of PTE and DVT. . PMID- 30279920 TI - Visceral malperfusion after thoracic endovascular aortic repair for type B aortic dissection in a post-abdominal aortic grafting patient. AB - A 69-year-old woman with a history of graft replacement for abdominal aortic aneurysm developed a complicated type B aortic dissection that resulted in renal malperfusion after thoracic endovascular aortic repair (TEVAR). The primary entry tear was formed at the aortic arch and the false lumen (FL) continued to the abdominal aorta. The distal end of the FL formed a pouch-like blind alley above the suture line of the bifurcated abdominal graft. The true lumen (TL) was compressed and caused severe limb ischemia. The right renal artery (rRA) originated from the FL. The patient had initially undergone emergent axillofemoral bypass for limb malperfusion. Three weeks later, restenosis of the TL caused visceral malperfusion, and a huge thrombus formed in the FL pouch. TEVAR expanded the TL and restored visceral vascularization. However, the expanded TL compressed the thrombus in the blind alley to the rRA orifice and caused right renal malperfusion. The history of abdominal graft replacement may have increased the risk of a thrombotic event after TEVAR. Primary TEVAR may have helped prevent thrombus formation in the FL pouch. . PMID- 30279921 TI - A case of acute heart failure due to myocardial infiltration of mycosis fungoides. AB - Mycosis fungoides (MF) has been reported to be the most common cutaneous lymphoma with a good prognosis and myocardial infiltration is clinically rare. We hereby report a case of rapidly progressing acute heart failure due to myocardial infiltration by MF. Perfusion cardiac magnetic resonance imaging (MRI) demonstrated a massive perfusion defect in the left ventricle (LV) where multiple nodular enhancement areas by delayed enhancement MRI could be documented in the postero-lateral wall of the LV, which resulted in a deterioration of the LV function and mitral regurgitation. Autopsy confirmed the myocardial infiltration by the MF, which corresponded with the MRI findings. . PMID- 30279922 TI - Long-standing persistent effects of atrial volume reduction combined with pulmonary vein isolation. AB - Although surgical left atrial (LA) volume reduction combined with mitral valve surgery and/or surgical ablation for atrial fibrillation has been reported to be effective, its long-term outcomes in the absence of mitral procedure are not well established. A 74-year-old man with two previous sternotomies-the first for pericardiectomy due to constrictive pericarditis and the second for mitral valve replacement with mechanical valve and tricuspid annuloplasty-presented with heart failure and thrombus in his giant left atrium (1291 mL), complicated by cerebral infarction. His electrocardiogram showed rate-controlled persistent atrial fibrillation. His mechanical valve was functioning well. A third atrial volume reduction combined with pulmonary vein isolation, without valve surgery, was performed. The postoperative course was uneventful, and the patient has remained asymptomatic with regular junctional rhythm and without any episodes of thromboembolism or re-dilation of LA (approximately 550 mL). His left ventricular filling improved with end-diastolic volume (96 mL vs 140 mL) and forced vital capacity (2.60 L vs 2.89 L) increased. Both remained relatively constant for 6 years. The combination of atrial volume reduction with pulmonary vein isolation prevented thromboembolism, improved left ventricular filling, and continued to improve symptoms associated with heart failure and respiratory condition for 6 years. . PMID- 30279924 TI - Percutaneous atrial septal defect closure through femoral and transjugular approaches in patients with interrupted inferior vena cava. AB - Femoral venous approach is the classic route of percutaneous atrial septal defect (ASD) closure. But in patients with interrupted inferior vena cava (IVC) with azygos continuation the normal connection is lost rendering transcatheter intervention more complicated and innovative approaches should be sought. Transhepatic approach has been used with success but this approach is technically demanding and could lead to major complications. We report successful percutaneous secundum ASD closure in 2 patients with interrupted IVC. Transjugular route was used to close the secundum ASD in a 15-month-old girl. Percutaneous ASD closure through femoral venous route was performed in a 49-year old woman. We found that both these approaches of percutaneous ASD device occlusion can be performed with success and safety. . PMID- 30279923 TI - Complete healing of spontaneous coronary artery dissection extending from the left main trunk to the left anterior descending and the left circumflex artery. AB - Spontaneous coronary artery dissection (SCAD) is defined as a spontaneous separation of the coronary artery wall that is not iatrogenic or related to trauma and usually affects young women. We describe a 65-year-old woman who presented with SCAD extending from the left main trunk involving the left anterior descending artery and the left circumflex artery, and coronary artery bypass graft surgery was performed to treat the dissection. Coronary angiography performed 3 months later, showed complete angiographic healing. A conservative management strategy is known to be associated with spontaneous angiographic healing in patients with SCAD who are hemodynamically stable. Healthcare providers should consider SCAD among the differential diagnoses in patients presenting with acute coronary syndrome, particularly in women. Further studies are needed to establish an optimal management strategy for SCAD. . PMID- 30279925 TI - Fourth mitral valve replacement in a 15-year span in a woman of childbearing age. AB - There is no report of four valve replacement surgeries in a woman during 15-year follow-up. A 23-year-old female was diagnosed at 7 years with rheumatic fever. She developed severe mitral regurgitation and at the same age a prosthetic valve was placed. In the next 15 years her mitral valve was changed 3 times because of clinical, echocardiographic, and histopathologic evidence of thrombosis. Her coagulation tests all showed infratherapeutic international normalized ratio and by the age of 15 years she had had an ischemic stroke with total recovery. She developed a normal pregnancy by the age of 19 years with no complications. This case exposes the complexity of the decision making that cardiologists face in terms of choosing the type of prosthetic valve that should be indicated in a woman of childbearing age. With each surgical valve replacement prognosis is less favorable and choosing the best therapy remains a challenge for the heart team. . PMID- 30279926 TI - Accessory and solitary main papillary muscle hypertrophy resulting in dynamic mid left ventricular obstruction: Contribution of multimodality imaging in highlighting of dynamic and structural abnormalities. AB - Solitary main and/or accessory papillary muscle (PM) hypertrophy may be an uncommon type of hypertrophic cardiomyopathy that does not meet all the usual criteria. The dynamic intraventricular obstruction related to this PM hypertrophy can be deleterious with an important clinical impact on patients. The mechanisms of such obstruction attracted a lot of attention in order to propose an appropriate treatment. We report a case of a 36-year-old man presenting with a chief complaint of progressively worsening exertional dyspnea. He had demonstrated labile systolic murmur for more than 3 years. Rest echocardiography revealed coexistence of a solitary main PM hypertrophy and additional accessory PM with no left ventricular outflow tract or mid ventricle obstructions. The patient underwent exercise stress echocardiography unmasking severe mid-ventricle obstruction (peak systolic gradient at exercise of 100 mmHg). There was no obvious parietal hypertrophy elsewhere. Cardiac magnetic resonance imaging provided us with anatomical arguments that could explain the dynamic process of obstruction. In fact, multimodality imaging has a determinant role in the screening of spatial configuration and structural abnormalities of PMs in order to avoid the misinterpreting of some atypical presentations of hypertrophic cardiomyopathy. . PMID- 30279927 TI - T-wave alternans in a case with systemic lupus erythematosus-related myocarditis. AB - A 42-year-old woman presented with fever, dyspnea, lower-leg edema, significant pulmonary congestion, pleural effusion, and severely reduced left ventricular contractions. She was resistant to treatment for heart failure, including catecholamines, furosemide, phosphodiesterase III inhibitors, and human atrial natriuretic peptide, and antibiotics failed to reduce her inflammation. She had renal dysfunction and hypocomplementemia and was positive for anti-nuclear and anti-ds-DNA antibodies. The patient was diagnosed with myocarditis and pleurisy associated with systemic lupus erythematosus (SLE). Prednisolone administration improved her general condition, reducing inflammation and improving left ventricular function. On day 1, an electrocardiography (ECG) revealed a T-wave inversion similar to a T-U complex configuration in leads II, aVF, and V3-6. By day 8, however, ECG showed prolonged corrected QT (QTc) and T-wave alternans (alternating beat-to-beat T-wave patterns) in lead V3-6. Careful ECG monitoring should be used to identify potentially fatal ventricular arrhythmias during the recovery phase of SLE-related myocarditis. . PMID- 30279929 TI - The utility of atrial overdrive pacing during catheter ablation of premature ventricular contractions originating from the posterior-superior process of the left ventricle. AB - A 76-year-old man presented with frequent premature ventricular contractions (PVCs). The electrophysiological findings revealed the origin of the PVCs was in the posterior-superior process of the left ventricle (PSP-LV), which is anatomically adjacent to the infero-medial aspect of the right atrium (RA). After a failed ablation from the LV, ablation in the RA eliminated the PVCs. During additional ablation, the atrio-his (AH) interval was monitored by atrial overdrive pacing, and ablation was terminated immediately after the AH interval prolonged to 174 ms. We believe that the atrial overdrive pacing was useful for monitoring the AH interval to prevent atrioventricular block during ablation of PVCs from the PSP-LV. . PMID- 30279928 TI - Restoration of vision by endovascular revascularization in Takayasu arteritis: A case series. AB - Takayasu arteritis (TA) is a rare, inflammatory vasculitis affecting aorta and its branches. Stenotic occlusive lesions of multiple arch arteries can cause severe cerebral ischemia leading to impaired vision. We present three consecutive young patients of TA with severe diminution of vision on upright posture, where we attempted restoration of sight by improving cerebral blood flow by percutaneous endovascular revascularization. All three patients could be successfully revascularized with substantial improvement in vision. There was no complication. On follow up, one patient developed recurrence of visual symptoms due to restenosis, which was successfully treated by cutting balloon angioplasty. The objective of this case series is to highlight the role of endovascular techniques in reversing visual loss in such situations. . PMID- 30279930 TI - Assessment of myocardial fibrosis using T1-mapping and extracellular volume measurement on cardiac magnetic resonance imaging for the diagnosis of radiation induced cardiomyopathy. AB - Radiation-induced heart disease (RIHD) is a serious side effect of thoracic radiation therapy (RT) and is associated with significant morbidity and mortality. Radiation-induced cardiomyopathy (RICM) is one of the manifestations of RIHD, which represents with left ventricular (LV) systolic and diastolic dysfunction due to myocardial fibrosis. Although the diagnosis of RIHD is challenging and is generally an exclusion diagnosis, multimodality imaging including echocardiography, cardiac computed tomography and cardiac magnetic resonance (CMR) imaging could help the diagnosis. Herein, we report a case of 70 years-old male, who had been treated with chemo-radiation therapy for early esophageal cancer, was suffered from medically refractory heart failure due to severely reduced LV systolic function and constrictive pericarditis 8 years after chemo-radiation therapy. Although no gadolinium-enhancement (LGE) was detected on CMR, T1 mapping depicted increased extracellular matrix volumes of 45%, which suggested global myocardial fibrosis. Histopathological analysis by endomyocardial biopsy (EBM) revealed marked degeneration of myocytes and interstitial fibrosis, while vacuolation in myocytes which is characteristics of chemotherapy induced cardiomyopathy was not specific by electron microscopy. Therefore, we diagnosed that the present case was likely to the RICM. . PMID- 30279931 TI - Brugada syndrome unmasked by malaria-induced fever. AB - Brugada syndrome is typically an autosomal dominant genetic disorder with variable expression, characterized by three specific electrocardiogram (ECG) patterns. While Type I Brugada ECG pattern is used as a classic marker for the disease, it is generally masked from ECG except in special cases such as malaria induced fever. This vignette highlights a unique clinical scenario that can lead to the unmasking of Brugada type 1 pattern. . PMID- 30279932 TI - Improved hemodynamics following endovascular treatment for acquired aortic coarctation: A case report. AB - A 38-year-old man underwent surgical repair of a type A aortic dissection. After aortic surgery, his left ventricular ejection fraction was progressively reduced from 65% to 15%, causing a refractory low cardiac output depending on the intravenous inotropes. There was a luminal stenosis of the descending aorta due to enlarged pseudolumen. The peak-to-peak pressure gradient at the stenosis was 25 mmHg, which was thought to contribute to the systolic dysfunction. He underwent thoracic endovascular aortic repair (TEVAR) with the use of a bare self expanding stent. After TEVAR, the peak-to-peak pressure gradient was decreased to 9 mmHg, resulting in hemodynamic improvement. . PMID- 30279933 TI - Trans-catheter aortic valve implantation without contrast using the Lotus mechanically-expanded heart valve. AB - Trans-catheter aortic valve implantation (TAVI) has become an established treatment for inoperable and high-surgical risk patients with severe, symptomatic aortic stenosis (AS). Post-procedural acute kidney injury (AKI) is a frequent complication following TAVI and is associated with increased mortality. Patients with pre-existing chronic renal impairment are at particularly high risk. The etiology of post-TAVI AKI is multi-factorial, but the principal procedural issues are contrast-induced nephropathy, and renal hypoperfusion secondary to intra procedural hypotension. We report a case of a TAVI in an 80-year-old patient with severe AS and significant chronic kidney disease (CKD), which was carried out without the use of contrast and with minimal procedural hypotension. Pre procedural imaging was carried out using 3D trans-esophageal echocardiography (TEE) rather than computed tomography (CT) to avoid contrast administration. The Lotus valve (Boston Scientific, Marlborough, MA, USA) was chosen due to a number of design features which minimize both the need for contrast injection and procedural hypotension during valve positioning and deployment. The procedure was carried out successfully and produced an excellent result with no decline in renal function. We believe that the approach of using TEE and the mechanically expanded Lotus valve illustrates an important therapeutic approach in patients with severe CKD. . PMID- 30279935 TI - Left subclavian and right femoral vein thrombosis in a pregnant patient with antithrombin deficiency. AB - Pregnancy is well-known risk factor for deep vein thrombosis (DVT), which usually occurs during the third trimester and in the left-sided lower extremity. We present a case of left subclavian and right femoral vein thrombosis in a pregnant woman with a gestational age of 10 weeks. A 39-year-old woman visited the emergency department complaining of acute pain and swelling of the left upper arm and right lower extremity. She showed swelling of the left upper arm and right lower extremity and a low antithrombin level of 40%. Ultrasound examination showed right femoral and left subclavian vein thrombosis. Her DVTs were treated with unfractionated heparin. Five months later, she received a cesarean delivery with intravenous unfractionated heparin and antithrombin replacement to prevent DVT, and she successfully gave birth. A genetic test for antithrombin deficiency confirmed hereditary antithrombin deficiency. DVT during pregnancy can occur in an upper extremity and at multiple sites. An undiagnosed coagulation disorder magnifies the risk of DVT in pregnant patients. We should examine all extremities for which there are complaints of pain and swelling with suspicion of DVT and consecutively search for an underlying coagulation disorder in pregnant patients with unusual clinical features of DVT. . PMID- 30279934 TI - Successfully treated eosinophilic granulomatosis with polyangiitis relapse presenting as myocarditis and followed by multimodality imaging. AB - A 60-year-old man with eosinophilic granulomatosis with polyangiitis (EGPA), which was diagnosed 12 years earlier and managed with prednisolone, was admitted to our hospital because of dyspnea and paresthesias in both hands. Laboratory test revealed peripheral eosinophilia along with elevated troponin T and brain natriuretic peptide (BNP). The patient's clinical picture was consistent with myocarditis and relapse of EGPA. Endomyocardial biopsy showed marked infiltration of eosinophils in myocardium, which confirmed relapse of EGPA with myocarditis. Thallium-201 and iodine-123-beta-methyl iodophenyl pentadecanoic acid dual single photon emission computed tomography (TL-BMIPP SPECT), as well as cardiac magnetic resonance imaging (CMR), also confirmed cardiac involvement. The patient was treated with methylprednisolone and improved dramatically. CMR and TL-BMIPP SPECT performed after discharge showed improvement of abnormal lesions, while anomalies detected by these modalities remained. This is a case of EGPA relapse presenting as myocarditis despite treatment with prednisolone. . PMID- 30279936 TI - Handball Research: State of the Art. PMID- 30279937 TI - Systematic Review and Meta-Analysis on Proximal-to-Distal Sequencing in Team Handball: Prospects for Talent Detection? AB - The proximal-to-distal sequence has previously been discussed in the light of performance and injury prevention. Sports biomechanics literature in general, and in team handball in specific, has claimed to be of importance to inform coaches on what constitutes a 'good' technical performance. However, hitherto no prospective studies exist on how this information may be used and this may in part be due to the general small sample sizes. We therefore performed a systematic review and meta-analysis of proximal-to-distal sequencing in team handball throwing motions. A total of fourteen articles were included in the systematic review. Meta-analyses were performed for the timing of maximal angles and angular velocities as well as initiation of joint angular velocities in the penalty throw, the standing throw with run-up and the jump shot of experienced team handball players. For the initiation of joint angular velocities, the overall sequence was estimated to start with pelvis rotation, followed by trunk rotation, trunk flexion, shoulder internal rotation and elbow extension. For maximal velocities, the sequence started with pelvis rotation, followed by trunk rotation, trunk flexion, elbow extension, and shoulder internal rotation (post ball release). The obtained results were discussed in the light of talent identification purposes. Limitations to individual study methodology and of the present meta-analysis were also discussed. Much more research will be necessary, but at the very least, this review can provide a starting point for evidence based discussions between movement scientists and team handball coaches to include proximal-to-distal sequencing as a measure of coordination to gauge early onset of talent. PMID- 30279938 TI - Influence of Physical Aspects and Throwing Velocity in Opposition Situations in Top-Elite and Elite Female Handball Players. AB - The relationship between anthropometric and physical characteristics of female handball players and throwing velocity is considered an important factor in handball performance. The aim of this study was to examine key differences in anthropometric and fitness characteristics between top elite and elite female players competing in the first Spanish handball league. A total of 89 players from the first Spanish handball league were divided into two groups, top elite (38) and elite (51) players, and assessed for anthropometric and fitness characteristics (throwing velocity, vertical jump and hand grip strength). A Student's t-test was used to determine whether a statistically significant difference between the two different levels of play occurred. Significant differences were found in age, body height, body mass, arm span, muscle mass, different girths (tensed and flexed arm, forearm, wrist, ankle), dominant hand width and length, different breadths (biacromial, bitrochanteric, bistyloid breadth and biepicondylar humerus) and fitness characteristics (hand grip strength and throwing velocity for different positions). Top elite players compared to elite players showed differences in anthropometric characteristics which were mainly located in the upper limbs and mostly were nonmodifiable aspects by training. Furthermore, the best players were able to maintain a high throwing velocity in different tactical situations. PMID- 30279939 TI - Relative Age Effect and the Re-Selection of Danish Male Handball Players for National Teams. AB - The relationship between the date of birth and expertise in various sports among both elite and youth level athletes is well established, and known as the relative age effect (RAE). However, new results in for example Canadian Hockey and British cricket and rugby have indicated a reversal of RAE among selected talents where the youngest athletes are more likely to remain selected than their older peers. As such, RAE may therefore depend on the age and the level of competition. The purpose of this study was therefore to analyse RAE from the youth to senior national level in a sample of successful Danish male national teams. The sample included 244 players from Danish under-19, under-21 and senior national levels. These players have been part of successful teams, winning 18 medals at 24 youth European and World championships and 8 medals during 12 years at the senior level. The results showed a significant RAE on both youth and national levels. However, RAE was less marked from the under-19 to under-21 and further to the senior national level. Results show that at the national youth level talent selection favours the relatively older players, of whom a larger proportion fails to be re-selected to the senior level compared to their younger peers. RAE appears to play a central and reversing role in the identification and re-selection in Danish male handball. The results also show that the presence of both a constant and constituent year structure affects RAE, even when introduced at late adolescence. PMID- 30279940 TI - Effect of Inspiratory Muscle Training on Performance of Handball Athletes. AB - Inspiratory muscle training (IMT) is a strategy that has been used to improve performance in different sports modalities. This study investigated the effects of an IMT program on respiratory muscle strength and resistance as well as aerobic physical performance (PP) of handball athletes. Nineteen 20 +/- 3 year old male athletes were allocated into an experimental (EG, n = 10) or a placebo group (PG, n = 9). Their respiratory muscle strength was evaluated by measuring the maximum inspiratory and expiratory pressures (MIP and MEP), muscular respiratory resistance by maximum voluntary ventilation (MVV) and aerobic PP by the cardiopulmonary exercise test. The study was designed to evaluate the effects of a 12-week IMT program with five sessions a week. A significant difference was observed in the pre and post IMT values of the MIP (170 +/- 34 to 262 +/- 33 cmH2O) and MEP (177 +/- 36 to 218 +/- 37 cmH2O) in the EG, and MIP (173 +/- 45 to 213 +/- 21 cmH2O) in the PG, with a large effect size for the MIP, when the groups were compared. MVV showed a significant increase (162 +/- 24 to 173 +/- 30 L) in the EG, with a small effect size. There was a significant difference in maximum oxygen uptake (54 +/- 8 to 60 +/- 7 ml/kg/min) in aerobic PP. Oxygen uptake at the respiratory compensation point (RCP) (46 +/- 6 to 50 +/- 5 ml/kg/min), with a moderate effect size for both variables, was observed in the EG after IMT. We concluded that IMT provided a significant increase in respiratory muscle strength and resistance, contributing to increased aerobic PP in the EG, which suggests that IMT could be incorporated in handball players' training. PMID- 30279941 TI - Foul or No Foul? Effects of Permitted Fouls on the Defence Performance in Team Handball. AB - Attacking phases in team handball are highly dynamic, characterized by fast movements and a high frequency of fast passes with the aim to score a goal. Consequently, the opposing/defending team tries to prevent successful offensive actions by restraining the offensive opportunities and the probabilities of scoring a goal. According to the rules, defensive players are allowed to use body contact (e.g. with bent arms) to get in and keep their optimal defending position. If such a contact is not in line with the rules (e.g. clutching or pushing) and results in a turnover of ball possession, a foul is called and a free-throw awarded. However, there is a lack of research answering the question if a permitted foul (without personal sanction) is an effective way to increase the probability of defending the own goal successfully, because afterwards the attacking team keeps possession of the ball. Thus, we investigated 1052 attacking phases during games at the elite level to verify whether fouls committed by a defender influenced successful attacking (goal vs. no goal). It was found that when the attack was interrupted by a permitted foul, 50.60% of the attacks ended with a goal. Yet, when no foul was committed, only 47.09% of the attacks ended with a goal, however, the analysis revealed that this difference was not significant. Therefore, we concluded that neither a strategy of stopping offensive actions by body contact nor avoiding fouls and focusing only on intercepting the ball were favourable solutions in successful defending in team handball. It seems effective to implement a defence strategy with clearly defined fouling zones and situations, to deal with the tactical possibility of permitted fouls in handball. This idea and further considerations are discussed for sports practice. PMID- 30279942 TI - Performance and Home Advantage in Handball. AB - The main objective of this research was to delve into the concept of playing handball at home from a classical perspective of previous studies. The emergence of regularities or certain patterns of play can be explained by the location of matches. Through an observational methodology and a nomothetic, monitoring and multidimensional design, thirty-nine European elite handball matches were selected (N = 39). A mixed 'ad hoc' registration system was designed. Records were made of the last three minutes of home and visiting games of which images were available. Two observers with observational methodology experience participated in the study. The quality of the records was dealt with in an intraobserver and interobserver way. Two different techniques were applied for the treatment of the data: a) detection of behavioral patterns by Theme (p < .005) (Magnusson, 2000) and b) Chaid decision trees (p < .05) using SPSSv.24. The results showed the existence of T-patterns according to the location (different T patterns: home: 1085; away: 1242) of the matches. The categories most involved in effective launches were unveiled. On the other hand, the Chaid model also showed the effect of location (p < .001): home-win (node 9) (n = 149, 69%), away-win (node 10) (n = 15, 16%) in handball. Crossing analysis offered enriched interpretations to advance in the home advantage concept. From this study, guidelines can be drawn that may help handball coaches to build training tasks as differences in behavioral patterns between home or away play in handball were identified. Thus, designing tasks considering a match location has requires specificity. PMID- 30279943 TI - The Relationship Between Early and Senior Level Participation in International Women's and Men's Handball. AB - International competitions at the youth elite level have become an important part of attempts to identify, foster and develop sporting talent. However, sports science scholars disagree strongly about the value and importance of such competitions because little is known about the relationship between early performance, at both the team and individual level, and later success in adult elite sports. The first aim of this study was therefore to explore the relationship between international match experience at the youth international team level and subsequent match experience at the junior and the senior international team levels. The second aim of this study was to explore the relationship between youth national team results and subsequent junior and senior national team results in international competitions. The individual-level analysis was based on official match participation statistics of all Norwegian handball players with either youth, junior and/or senior national team experience (n = 657) between the years 1993 and 2017. The team level analysis was based on team result rankings from the handball European and World Championships at the youth, junior and senior national team levels during this period. Statistical analysis at the individual level showed a significant difference between those handball players who did and did not have international match exposure at the youth and junior levels, and the number of matches they played at the senior international team level. No to weak correlations were found between the number of matches played at the youth, junior and senior international team levels. Statistical analysis at the team level showed a strong correlation between result rankings at the youth, junior and senior international team levels. Collectively, these findings suggest that having youth and junior international experience is strongly associated with the number of matches played at the senior international level. However, the number of matches played at the youth and junior international levels does not appear to determine success or predict which players will or will not achieve success at the senior international level. PMID- 30279944 TI - Differences in Speed and Power Capacities Between Female National College Team and National Olympic Team Handball Athletes. AB - The aim of this study was to compare and examine differences in several neuromuscular assessments between female national Olympic team (Rio-2016) and national college team handball players (2015-Gwangju Summer Universiade). Twenty eight elite female handball players of the national Brazilian Olympic (n = 12) and college (n = 16) teams participated in this study. The Olympic and college athletes performed the following speed-power tests assessing mean propulsive power (MPP) in loaded jump squat (JS) and bench press (BP) exercises, unloaded squat and countermovement jumps (SJ and CMJ), sprint performance over 5-, 10-, and 20-m, and change of direction ability in a standard Zig-zag test and a T Test. The differences between Olympic and college team performances in all variables were analyzed using the magnitude-based inference. The Olympic group presented likely higher performances in the SJ, CMJ, and MPP JS and very likely higher performances in the MPP BP and T-Test than the college group. The differences in the linear sprint velocity in 5-, 10-, and 20-m tests as well as in the Zig-zag test were all rated as unclear. These findings may have substantial implications for the development of effective strength-power training and testing strategies in elite handball. In addition, coaches and researchers can use these data to create efficient talent identification programs for youth handball players. PMID- 30279945 TI - Changes of Strength and Maximum Power of Lower Extremities in Adolescent Handball Players During a Two-year Training Cycle. AB - The aim of the study was to investigate changes of strength and power of the lower extremities in adolescent handball players during a two-year training cycle. Thirty-one male handball players (age 16.0 +/- 0.2 years, body mass 81.4 +/- 9.7 kg, body height 188.2 +/- 6.4 cm) took part in this study. All tests were conducted three times at the beginning of a one-year training programme. The maximum joint torque (JT) of flexors and extensors of the elbow, shoulder, hip, knee and trunk was measured under static conditions. Power of lower extremities was assessed with a repeated sprint ability (RSA) test on a cycloergometer and jump tests: akimbo counter-movement jump (ACMJ), counter-movement jump (CMJ) and spike jump tests on a force plate. Peak power (PP) increased from 914.8 +/- 93.9 to 970.0 +/- 89.2 and 1037.8 +/- 114.4 W (p < 0.05) following the RSA test results. Maximum power increased significantly (p < 0.05) in ACMJ (1951.9 +/- 359.7 to 2141.9 +/- 378.5 and 2268.5 +/- 395.9 W) and CMJ tests (2646.3 +/- 415.6 to 2831.2 +/- 510.8 and 3064.6 +/- 444.5 W). Although significant differences in JT (p < 0.05) were observed during the two year period, their values related to body mass for the lower right extremity, sum of the trunk and sum of all muscle groups increased significantly between the first and the second measurement (from 13.7 +/- 1.8 to 14.58 +/- 1.99 N.m.kg-1, from 9.3 +/- 1.5 to 10.39 +/- 2.16 N.m.kg-1, from 43.4 +/- 5.2 to 46.31 +/- 6.83 N.m.kg-1, respectively). The main finding of the study is that PP in the RSA test and maximal power in the ACMJ and CMJ increase in relation to training experience and age in the group of youth handball players. PMID- 30279946 TI - Muscle Strength Variations of Knee Joint Muscles in Elite Female Handball Players after Pre-Season Conditioning. AB - Monitoring seasonal variations in strength performance and the relative risk of injury indicators related to strength of hamstring (H) and quadriceps (Q) in female elite athletes is beneficial for the training process. The aim of this study was to examine and compare the level of muscle strength, the conventional ratio (HCONC/QCONC) as well as two functional and strength ratios reflecting the movement of knee extension (HECC/QCONC) and flexion (HCONC/QECC), and the bilateral percentage strength deficit (BSD) in elite female handball players. The concentric and eccentric isokinetic peak torque was measured at an angular velocity of 60 degrees /s on three occasions (in-season cessation, 4 weeks of rest followed by 4 weeks of individual conditioning and 6 weeks of group conditioning) in eleven female handball players (age: 23.1 +/- 3.5 years, body height: 1.73 +/- 0.6 m). According to ANOVA results, the BSD of H muscles in the concentric mode decreased between the in-season cessation and the end of the pre season, and HCONC/QCONC increased at the beginning of the pre-season and at the end of the pre-season in comparison with inseason cessation measurement. The effect size analyses showed that the off-season rest followed by 10 weeks of the conditioning programme increased Q and H strength in comparison with the previous season with a large effect. Coaches should include progressive conditioning in the pre-season phase to decrease the bilateral strength deficit and to support further conditioning development. PMID- 30279947 TI - Diurnal Variations in Physical Performance: Are there Morning-to-Evening Differences in Elite Male Handball Players? AB - The purposes of this study were to determine: 1) morning-to-evening differences in physical performance with and without a ball; and 2) associations between sleep outcomes (duration and quality) and physical performance in handball players. Sixteen elite, male handball players (25.4 +/- 5.8 yr, 94.0 +/- 7.4 kg, 193.5 +/- 7.5 cm) completed physical performance tests without a ball (a zig-zag test assessing closed-skill agility, linear sprints, and countermovement (CMJ) and squat jumps) and with a ball (a zig-zag test and linear sprints) in the morning and evening. In addition, sleep quality and quantity during the night before testing were obtained using self-reported measures. Superior physical performance was evident in all tests during the evening compared to the morning hours (p < 0.003). Specifically, jump height was moderately (effect size (ES) = 0.73 to 1.02) higher during the evening. Similarly, moderate (ES = 1.17) and large (ES = 1.67) improvements in zig-zag test performance were apparent during the evening with and without the ball, respectively. Also, large to very large (ES = 1.29 to 2.09) increases in sprint performance with and without the ball were evident in the evening. No significant correlations (p > 0.05) were apparent between sleep duration and quality and physical performance in both the morning and evening sessions. Diurnal variations in physical performance were apparent in elite male handball players with enhanced performance with and without the ball in the evening compared to morning hours. These findings indicate that morning-to evening differences in physical performance should be considered when developing conditioning plans or preparing for competition in handball. PMID- 30279949 TI - Effects of Short-Term Plyometric Training on Physical Performance in Male Handball Players. AB - The aim of this study was to compare the effects of plyometric and jump training on physical performance in young male handball players. Twenty-six young male handball players were divided into two sub-groups to perform a five-week pre season training programme supplemented with two ground-reactive protocols with an equal number of jumping exercises referred as to ground contacts: plyometric training (PLY; n = 14) and standard jump training (CON; n = 12). Before and after training, repeated sprint ability (RSA), jumping ability (JA), maximal oxygen uptake (VO2max) and aerobic power at the anaerobic threshold (PAT) were measured. A two-factor analysis revealed significant time effects with improvements in fat mass (p = 0.012), maximal power during the incremental cycling test (p = 0.001) and PAT (p < 0.001), power decline (PDEC) and maximal power (Pmax) in the 5th repetition (p < 0.05 and p < 0.01, respectively). The training-induced changes in absolute and relative peak power in the RSA test and absolute VO2max approached significance (p = 0.06, p = 0.053 and p = 0.06). No intervention time * exercise protocol effects were observed for any indices of JA, RSA and aerobic capacity. A five-week pre-season conditioning programme supplemented with only 15 sessions of plyometric exercise did not induce any additional benefits, compared to a matched format of standard jump training, in terms of improving jumping performance and maximal power in the RSA test. Aerobic capacity and the fatigue index in RSA were maintained under these two training conditions. PMID- 30279950 TI - Modification of Strength Training Programs in Handball Players and its Influence on Power During the Competitive Period. AB - A high level of muscle power is necessary for the effective use of technique during handball competitions. The presented research concentrated on comparing the effectiveness of two training modes directed towards the development of muscle power - plyometric and traditional strength training. Furthermore, we evaluated whether resistance training performed twice a week was sufficient to guarantee an increase in muscle power of handball players. We also investigated whether strength training designed according to the "waving" model (one training session per week oriented towards the development of maximal strength and one towards the development of power) was sufficient to increase muscle power in handball players. The study included 28 professional handball players who were divided into 3 groups: Group 1 subjected to additional strength training (8 individuals), Group 2 subjected to traditional plyometric training (8 individuals) and Group 3 following standard training (12 individuals). Research was conducted at the beginning and at the end of the 1st round of competitions and consisted of the following measurements: CMJ (countermovement jump) and SJ (squat jump), a 10-s trial on a cycle-ergometer and ball-throwing velocity. Analysis of the results showed that both the plyometric and strength training programs induced a statistically significant increase in jumping height and generated power during the CMJ. The group subjected to additional strength training achieved greater increases in CMJ power than the group carrying out plyometric training, which in case of the CMJ peak power turned out to be statistically significant (p < 0.05). Different results were obtained when studying changes in the flight speed of the thrown ball; the group undergoing plyometric training registered minor increases (significant in the standing throw ), and there were decreases in the flight speed of the thrown ball (significant in the leaning back throw) in the group following the traditional strength training program. PMID- 30279948 TI - The Relationship Between Handball Players and Alcohol and Smoking Habits. AB - Recent studies have revealed that sport activity is a protective factor regarding smoking, but a risk factor for alcohol abuse. Considering these findings, it is necessary to investigate the occurrence of substance misuse. Sports that are associated with a substantial amount of physical/mental stress are very interesting from the perspective of substance misuse (e.g., handball). This research was performed to more closely study the population engaged in handball regarding the risk for alcohol and/or tobacco consumption. The sample of respondents consisted of 150 senior handball players who were members of 9 first league handball clubs from Croatia and abroad. The respondents were grouped into sub-samples according to sex, age, experience, the number of weekly training sessions and their social environment (clubs). Alcohol consumption data were obtained using the AUDIT questionnaire. The differences between groups were tested using the Kruskal-Wallis and Mann-Whitney U tests. The study revealed that handball players engaged in alcohol misuse, and they were grouped in the harmful drinking category (AUDIT score, 16-19 for all groups). Regarding tobacco product consumption, the risk groups were women (who smoked significantly more than men, MWU test: Z = 3.30. p < 0.001), handball players with less experience (who smoked significantly more than experienced players, MWU test: Z = 3.68, p < 0.001). Borderline significance was observed for the impact made by social environments, and age was not a significant predictor of tobacco consumption. Regarding alcohol consumption, the highest hazard group were national handball players, who drank much more than foreign players did (MWU test: Z = 2.04, p = 0.04); however, sex, age, experience and training habits were not alcohol consumption predictors in handball. This study reveal that the typical behaviors regarding alcohol and tobacco consumption followed by the general population do not apply to handball players. Targeted prevention can be much more precisely established considering this research. PMID- 30279951 TI - Postural Stability in Goalkeepers of the Polish National Junior Handball Team. AB - The aim of the study was to assess postural stability of goalkeepers from the Polish national junior handball team. Eleven juniors of the Polish national handball team (age 16.82 +/- 1.6 years, body height 191.27 +/- 3.1 cm, body mass 88.41 +/- 12.26 kg, BMI 24.18 +/- 3.22 kg/m2) were selected for the study. The Biodex Balance System and AccuGait AM!TI platform were used to evaluate postural stability. The obtained results indicated good postural stability of the subjects. During the Biodex Balance System platform tests, all subjects presented very good postural stability and maintained within Zone A. Postural sway was greater in the sagittal plane compared to the frontal one. Most of the participants demonstrated slight backward tilts, but maintained in Quadrant IV. During the AccuGait AMTI platform trial, Path Length and Average COP Speed significantly increased in the test performed with closed eyes. Furthermore, there were significant positive correlations between the number of variables obtained during the Biodex Balance System and AccuGait AMTI tests. Proper and stable posture are necessary conditions to be met to carry out most free movements and locomotion. They play a significant role in the game of a handball goalkeeper and for that reason, postural stability testing of handball goalkeepers is an important element of coordination training. Thus, the use of postural stability exercises implementing the biofeedback method on stabilo and dynamometric platforms is practical and justifiable. PMID- 30279952 TI - Relation between cutaneous and extracutaneous complications in pediatric patients with type 1 diabetes. AB - Background: The relationship between cutaneous and extracutaneous complications in pediatric patients with type 1 diabetes is unclear. Objective: The objective of the current study is to investigate the relationship between skin disorders and diabetic microangiopathic changes in pediatric and adolescent patients with type 1 diabetes. Patients and methods: Eighty patients with type 1 diabetes and 50 healthy controls were enrolled in the study. All recruited patients were followed up monthly for a total period of 12 month. Monthly visit included thorough clinical examination with system review, as well as whole-body cutaneous examination. HbA1c was assessed every 3 month. Twenty-four hours urine was collected for measurement of urinary albumin. Results: Fifty percent of the screened diabetic cohort had diabetic nephropathy (DN). The overall prevalence of cutaneous lesion among the studied diabetic cohort was high (72.5%), with cutaneous infections (40%) and xerosis (30%) being the most prevalent. The frequency of cutaneous infections, xerosis and rubeosis faciei was higher in patients with nephropathy than in those without nephropathy. Conclusion: cutaneous affection in patients with diabetes may be a clue to the presence of associated microangioapthic complications. The significant association between diabetic nephropathy and cutaneous lesions support the concept that cutaneous lesion in diabetes is a reflection of diabetic angiopathy, highlighting the importance of identifying patients at risk of other microvascular complications.

PMID- 30279953 TI - Acanthosis nigricans in the knuckles: An early, accessible, straightforward, and sensitive clinical tool to predict insulin resistance. AB - Any clinical/biochemical marker revealing obesity or diabetes before their appearance is valuable. Insulin resistance (IR) is present in both disorders many years before occurrence. Accordingly, we determined whether acanthosis nigricans (AN) in the knuckles is associated to higher insulin and homeostasis model assessment for estimated insulin resistance (HOMA-IR) index values, and assessed the influence of body-mass index (BMI) and the diagnostic performance of AN in the knuckles to detect IR. In this cross-sectional controlled study, we included men or women, 18 to 23 years old, with or without AN in the knuckles. In 149 cases with AN in the knuckles and 145 controls, fasting insulin was higher in cases (13.45 uU/mL +/- 7.8 vs. 8.59 uU/mL +/- 3.63, P < .001, respectively). Mean HOMA-IR index was also higher (2.86 +/- 1.68 vs. 1.78 +/- 0.77, P < .001). A significant increase in fasting insulin and HOMA-IR values between and within BMI groups from normal through obese category was identified in controls and cases. By multivariate regression analysis, cases with normal BMI were significantly associated to a HOMA-IR >=2.5 (OR = 3.09, CI95% = 1.75-5.48, P = .001). A model of AN in the knuckles, normal BMI, and increased waist circumference allowed identifying 2 out of 3 cases with HOMA-IR index >=2.5. AN in the knuckles could be addressed with two aims: as an easy, accessible, and costless diagnostic tool suggesting hyperinsulinemia secondary to IR, and, an early marker of IR even in the absence of overweight or obesity.

PMID- 30279956 TI - Modeling and antitumor studies of a modified L-penetratin peptide targeting E2F in lung cancer and prostate cancer. AB - E2F1-3a overexpression due to amplification or to mutation or loss of the retinoblastoma gene, induces genes involved in DNA synthesis and leads to abnormal cellular proliferation, tumor growth, and invasion. Therefore, inhibiting the overexpression of one or more of these activating E2Fs is a recognized target in cancer therapeutics. In previous studies we identified by phage display, a novel 7-mer peptide (PEP) that bound tightly to an immobilized consensus E2F1 promoter sequence, and when conjugated to penetratin to increase its uptake into cells, was cytotoxic to several malignant cell lines and human prostate and small cell lung cancer xenografts. Based on molecular simulation studies that showed that the D-Arg penetratin peptide (D-Arg PEP) secondary structure is more stable than the L-Arg PEP, the L-Arg in the peptide was substituted with D-Arg. In vitro studies confirmed that it was more stable than the L- form and was more cytotoxic as compared to the L-Arg PEP when tested against the human castrate resistant cell line, DU145 and the human lung cancer H196 cell line. When encapsulated in PEGylated liposomes, the D-Arg-PEP potently inhibited growth of the DU145 xenograft in mice. Our findings validate D- Arg PEP, an inhibitor of E2F1and 3a transcription, as an improved second generation drug candidate for targeted molecular therapy of cancers with elevated levels of activated E2F(s). PMID- 30279958 TI - Glioblastoma in the setting of prior lower grade gliomas - insights from SEER database. AB - Introduction: Secondary glioblastomas (GBs) constitute a small subset of all GBs and tend to arise after a lower grade glioma. Though knowledge regarding this subset has gained traction in recent years, its definition continues to evolve, complicating its clinical management. Investigation of epidemiology and survival patterns may help provide needed insights. Results: The age at GB diagnosis is significantly lower (46.22 vs 60.25 years) for group B. The distribution among type of GB (glioblastoma, giant cell glioblastoma, or gliosarcoma) was significantly different, with no diagnosis of giant cell GB in Group B. Compared to Group A, Group B exhibited a higher proportion of females, not married, smaller tumors, no GTR, and no radiation (all p < 0.05). GB-related observed survivals were comparable. Cox regression with inclusion of co-variates reveal no significant influence of GB group on observed survival. Regarding group B, mean age was 40.197 for diagnosis of initial lower grade glioma. The most common initial ICD-O-3 pathology was oligodendroglioma, NOS; astrocytoma, NOS; astrocytoma, anaplastic; and mixed glioma. Methods: The SEER-18 registry was queried for patients with GBs. Patients were further classified into two GB groups: Group A - those with GB as the only primary tumor, and Group B - those with GB as a 2nd primary or subsequent tumor and with history of lower grade gliomas. Demographics and clinical factors were compared between group A and B. Appropriate statistics were employed to calculate incidences and differences among factors and GB-related survivals between the groups. Conclusions: Overall, Group B develops GBs at an earlier age, but observed survival remains similar to those with GBs as the only primary. Moreover, this subset also exhibit different proportions of the types of GBs, and well as differences in other key clinical factors (namely, gender and tumor size at presentation). Prior treatments for lower grade gliomas likely explain some of the differences noted regarding management course after diagnosis of GB. PMID- 30279957 TI - Outcome analysis of Phase I trial patients with metastatic KRAS and/or TP53 mutant non-small cell lung cancer. AB - KRAS and TP53 mutations, which are the most common genetic drivers of tumorigenesis, are still considered undruggable targets. Therefore, we analyzed these genetic aberrations in metastatic non-small cell lung cancer (NSCLC) for the development of potential therapeutics. One hundred eighty-five consecutive patients with metastatic NSCLC in a phase 1 trial center were included. Their genomic aberrations, clinical characteristics, survivals, and phase 1 trial therapies were analyzed. About 10%, 18%, 36%, and 36% of the patients had metastatic KRAS+/TP53+, KRAS+/TP53-,KRAS-/TP53+, and KRAS-/TP53- NSCLC, respectively. The most common concurrent genetic aberrations beside KRAS and/or TP53 (>5%) were KIT, epidermal growth factor receptor, PIK3CA, c-MET, BRAF, STK11, ATM, CDKN2A, and APC. KRAS+/TP53+ NSCLC did not respond well to the phase 1 trial therapy and was associated with markedly worse progression-free (PFS) and overall (OS) survivals than the other three groups together. KRAS hotspot mutations at locations other than codon G12 were associated with considerably worse OS than those at this codon. Gene aberration-matched therapy produced prolonged PFS and so was anti-angiogenesis in patients with TP53 mutations. Introduction of the evolutionary action score system of TP53 missense mutations enabled us to identify a subgroup of NSCLC patients with low-risk mutant p53 proteins having a median OS duration of 64.5 months after initial diagnosis of metastasis. These data suggested that patients with metastatic dual KRAS+/TP53+ hotspot-mutant NSCLC had poor clinical outcomes. Further analysis identified remarkably prolonged survival in patients with low-risk mutant p53 proteins, which warrants confirmatory studies. PMID- 30279959 TI - Metabolite quantification of faecal extracts from colorectal cancer patients and healthy controls. AB - Colorectal cancer (CRC), a primary cause of morbidity and mortality worldwide is expected to rise in the coming years. A better understanding of the metabolic changes taking place during the disease progression is needed for effective improvements of screening strategies and treatments. In the present study, Nuclear Magnetic Resonance (NMR) metabolomics was used to quantify the absolute concentrations of metabolites in faecal extracts from two cohorts of CRC patients and healthy controls. The quantification of over 80 compounds revealed that patients with CRC had increased faecal concentrations of branched chain fatty acids (BCFA), isovalerate and isobutyrate plus valerate and phenylacetate but diminished concentrations of amino acids, sugars, methanol and bile acids (deoxycholate, lithodeoxycholate and cholate). These results suggest that alterations in microbial activity and composition could have triggered an increase in utilisation of host intestinal slough cells and mucins and led to an increase in BCFA, valerate and phenylacetate. Concurrently, a general reduction in the microbial metabolic function may have led to reduced levels of other components (amino acids, sugars and bile acids) normally produced under healthy conditions. This study provides a thorough listing of the most abundant compounds found in human faecal waters and presents a template for absolute quantification of metabolites. The production of BCFA and phenylacetate in colonic carcinogenesis warrants further investigations. PMID- 30279960 TI - Single-cell transcriptomes reveal the mechanism for a breast cancer prognostic gene panel. AB - The clinical benefits of the MammaPrint(r) signature for breast cancer is well documented; however, how these genes are related to cell cycle perturbation have not been well determined. Our single-cell transcriptome mapping (algorithm) provides details into the fine perturbation of all individual genes during a cell cycle, providing a view of the cell-cycle-phase specific landscape of any given human genes. Specifically, we identified that 38 out of the 70 (54%) MammaPrint(r) signature genes are perturbated to a specific phase of the cell cycle. The MammaPrint(r) signature panel derived its clinical prognosis power from measuring the cell cycle activity of specific breast cancer samples. Such cell cycle phase index of the MammaPrint(r) signature suggested that measurement of the cell cycle index from tumors could be developed into a prognosis tool for various types of cancer beyond breast cancer, potentially improving therapy through targeting a specific phase of the cell cycle of cancer cells.

AB - Purpose: Prostate cancer is most common tumor in men causing significant patient mortality and morbidity. In newer diagnostic/therapeutic agents PSMA linked ones are specifically important. Analysis of textural heterogeneity parameters is associated with determination of innately aggressive and therapy resistant cell lines thus emphasizing their importance in therapy planning. The objective of current study was to assess predictive ability of tumor textural heterogeneity parameters from baseline 68Ga-PSMA PET prior to 177Lu-PSMA therapy. Results: Entropy showed a negative correlation (rs = -0.327, p = 0.006, AUC = 0.695) and homogeneity showed a positive correlation (rs = 0.315, p = 0.008, AUC = 0.683) with change in pre and post therapy PSA levels. Conclusions: Study showed potential for response prediction through baseline PET scan using textural features. It suggested that increase in heterogeneity of PSMA expression seems to be associated with an increased response to PSMA radionuclide therapy. Materials and Methods: Retrospective analysis of 70 patients was performed. All patients had metastatic prostate cancer and were planned to undergo 177Lu-PSMA therapy. Pre-therapeutic 68Ga- PSMA PET scans were used for analysis. 3D volumes (VOIs) of 3 lesions each in bones and lymph nodes were manually delineated in static PET images. Five PET based textural heterogeneity parameters (COV, entropy, homogeneity, contrast, size variation) were determined. Results obtained were then compared with clinical parameters including pre and post therapy PSA, alkaline phosphate, bone specific alkaline phosphate levels and ECOG criteria. Spearman correlation was used to determine statistical dependence among variables. ROC analysis was performed to estimate the optimal cutoff value and AUC. PMID- 30279963 TI - A safety study of newly generated anti-podoplanin-neutralizing antibody in cynomolgus monkey (Macaca fascicularis). AB - Hematogenous metastases are enhanced by platelet aggregation induced by tumor cell-platelet interaction. Podoplanin is a key molecule to enhance the platelet aggregation and interacts with C-type lectin-like receptor 2 (CLEC-2) on platelet via PLAG domains. Our previous reports have shown that blocking podoplanin binding to platelets by neutralizing antibody specific to PLAG4 domain strongly reduces hematogenous metastasis. However, podoplanin is expressed in a variety of normal tissues such as lymphatic vessels and the question remains whether treatment of tumors with anti-podoplanin neutralizing antibodies would be toxic. Monkeys are the most suitable species for that purpose. PLAG3 and PLAG4 domains had high homology among various monkey species and human. PLAG domain deleted mutants were indicated that monkey PLAG4 domain played a more crucial role in podoplanin-induced platelet aggregation than did the PLAG3 domain as in human. Moreover, newly established neutralizing antibodies (1F6, 2F7, and 3F4) targeting the monkey PLAG4 domain blocked interaction between monkey podoplanin and CLEC-2. Especially, the 2F7 neutralizing antibody strongly suppressed platelet aggregation and pulmonary metastasis. Furthermore, inhibiting podoplanin function with 2F7 neutralizing antibody exhibited no acute toxicity in cynomolgus monkeys. Our results suggested that targeting podoplanin with specific neutralizing antibodies may be an effective anticancer treatment. PMID- 30279961 TI - The vesicular transfer of CLIC1 from glioblastoma to microvascular endothelial cells requires TRPM7. AB - Chloride intracellular channel 1 (CLIC1) is highly expressed and secreted by human glioblastoma cells and cell lines such as U87, initiating cell migration and tumor growth. Here, we examined whether CLIC1 could be transferred to human primary microvascular endothelial cells (HMEC). We previously reported that the oncogenic microRNA, miR-5096, increased the release of extracellular vesicles (EVs) by which it increased its own transfer from U87 to surrounding cells. Thus, we also examined its effect on the CLIC1 transfer. In homotypic cultures, miR 5096 did not increase the expression of CLIC1 in U87 nor in HMEC. However, the endothelial CLIC1 level increased after exposure to EVs released by U87, and even more by miR-5096-loaded U87. The EVs-transferred CLIC1 was active in HMEC, promoting endothelial sprouting in matrigel. Cell exposure to EVs induced cytosolic Ca2+ spikes which were dependent on the transient receptor potential melastatin member 7 (TRPM7). TRPM7 silencing prevented Ca2+ spikes and the subsequent CLIC1 delivery into HMEC. Our data suggest that the vesicular transfer of CLIC1 between cells requires TRMP7 expression in recipient endothelial cells. How the vesicular transfer of CLIC1 is modulated in cancer therapy is a future challenge. PMID- 30279964 TI - Intratumor heterogeneity of HMCN1 mutant alleles associated with poor prognosis in patients with breast cancer. AB - Human breast cancers comprise a complex and highly heterogeneous population of tumor cells. Intratumor heterogeneity is an underlying cause of resistance to effective therapies and disease recurrence. To explore prognostic factors based on intratumor heterogeneity, we analyzed genomic mutations in breast cancer patients registered in The Cancer Genome Atlas. We calculated the variant allele frequency (VAF) at each mutation site and evaluated the associations of VAFs with the prognosis of breast cancer. VAFs of HMCN1 correlated with the prognosis and lymph node status. Although the detailed function of HMCN1 remains unknown, it is located in extracellular matrix and the mutation in the gene might be associated with cancer cell invasion and metastasis. This finding suggests that HMCN1 is a potential metastatic factor and can be a candidate gene for targeted breast cancer therapy. PMID- 30279965 TI - Assessing the efficacy of androgen receptor and Sox10 as independent markers of the triple-negative breast cancer subtype by transcriptome profiling. AB - The Androgen Receptor (AR) has recently garnered a lot of attention as a potential biomarker and therapeutic target in hormone-dependent cancers, including breast cancer. However, several inconsistencies exist within the literature as to which subtypes of breast cancer express AR or whether it can be used to define its own unique subtype. Here, we analyze 1246 invasive breast cancer samples from the Cancer Genome Atlas and show that human breast cancers that have been subtyped based on their HER2, ESR1, or PGR expression contain four clusters of genes that are differentially expressed across all subtypes. We demonstrate that Sox10 is highly expressed in approximately one-third of all HER2/ESR1/PGR-low tumors and is a candidate biomarker of the triple-negative subtype. Although AR expression is acquired in many breast cancer cases, its expression could not define a unique subtype. Despite several reports stating that AR expression is acquired in HER2/ESR1/PGR triple-negative cancers, here we show that a low percentage of these cancers express AR (~20%). In contrast, AR is highly expressed in HER2-positive or ESR1/PGR-positive cancers (> 95%). Although AR expression cannot be used as an independent subtype biomarker, our analysis shows that routine evaluation of AR expression in tumors which express HER2, ESR1 and/or PGR may identify a unique subset of tumors which would benefit from anti androgen based therapies. PMID- 30279966 TI - Loss of Gadd45b accelerates BCR-ABL-driven CML. AB - Gadd45b is a member of Gadd45 stress sensor protein family that also includes Gadd45a & Gadd45g. To investigate the effect of Gadd45b in bcr-abl oncogene driven chronic myeloid leukemia (CML) development, syngeneic wild type lethally irradiated mice were reconstituted with either wild type or Gadd45b null myeloid progenitors transduced with a retroviral vector expressing BCR-ABL. Loss of Gadd45b was observed to accelerate BCR-ABL driven CML development with shortened median mouse survival time. BCR-ABL Gadd45b deficient CML progenitors exhibited increased proliferation and decreased apoptosis, associated with hyper-activation of c-Jun NH2-terminal kinase and Stat5. These results provide novel evidence that gadd45b, like gadd45a, functions as a suppressor of BCR-ABL driven leukemia, albeit via a different mechanism. PMID- 30279967 TI - N-(2'-Hydroxyphenyl)-2-propylpentanamide (OH-VPA), a histone deacetylase inhibitor, induces the release of nuclear HMGB1 and modifies ROS levels in HeLa cells. AB - N-(2'-Hydroxyphenyl)-2-propylpentanamide (OH-VPA) is a valproic acid (VPA) derivative with improved antiproliferative activity toward breast cancer (MCF-7, MDA-MB-231, and SKBr3) and human cervical cancer cell lines (HeLa) compared to that of VPA. However, the pharmacological mechanism of OH-VPA activity remains unknown. High-mobility group box 1 (HMGB1) is an important enzyme that is highly expressed in tumor cells and has a subcellular localization that is dependent on its acetylation or oxidative state. Therefore, in this study, we analyzed changes in HMGB1 sub-cellular localization and reactive oxygen species (ROS) as well as changes in HeLa cell viability in response to treatment with various concentrations of OH-VPA. This compound is formed by the covalent bond coupling VPA to a phenol group, which is capable of acting as a free radical scavenger due to its chemical similarities to quercetin. Our results show that OH-VPA induces nuclear to cytoplasmic translocation of HMGB1, as demonstrated by confocal microscopy observations and infrared spectra that revealed high quantities of acetylated HMGB1 in HeLa cells. Cells treated with 0.8 mM OH-VA exhibited decreased viability and increased ROS levels compared with the lower OH-VPA concentrations tested. Therefore, the antiproliferative mechanism of OH-VPA may be related to histone deacetylase (HDAC) inhibition, as is the case for VPA, which promotes high HMBG1 acetylation, which alters its subcellular localization. In addition, OH-VPA generates an imbalance in cellular ROS levels due to its biochemical activity. PMID- 30279969 TI - Meta-analysis of the likelihood of FOXC2 expression in early- and late-stage tumors. AB - Background: Aberrations in the expression of the transcription factor forkhead box C2 (FOXC2) have been linked to a number of malignancies. Here, we characterized the relationship between FOXC2 and cancer progression by conducting a meta-analysis of studies that reported the frequency of FOXC2 expression in tumors of different stages (T1, T2, T3, T4). Methods: Relevant articles were retrieved from the Medline database by searching for the terms "FOXC2" and "cancer"; then, the retrieved articles were reviewed individually, and studies that were of multivariate cohort design, evaluated FOXC2 expression via immunohistochemical staining, and assessed the relationship between FOXC2 expression and cancer T-stage were included in our meta-analysis. Results: Our search terms identified 139 studies, 9 of which met all inclusion criteria. A total of 1433 tumor samples were evaluated in the 9 studies; 596 samples were from early-stage (T1-T2) tumors, and 838 were from late-stage (T3-T4) tumors. FOXC2 was expressed in 46.0% of all samples, in 32.4% of early-stage tumor samples, and in 55.6% of late-stage tumor samples. When calculated relative to early-stage samples, the pooled risk for FOXC2 expression in late-stage samples was 1.367 (95% CI = 1.103-1.695, p = 0.004). Conclusion: The results from our meta-analysis of 9 studies indicate that FOXC2 is 36.7% more likely to be expressed in late-stage tumors than in early-stage tumors. PMID- 30279968 TI - Genetic disruption of calpain-1 and calpain-2 attenuates tumorigenesis in mouse models of HER2+ breast cancer and sensitizes cancer cells to doxorubicin and lapatinib. AB - Calpains are a family of calcium activated cysteine proteases which participate in a wide range of cellular functions including migration, invasion, autophagy, programmed cell death, and gene expression. Calpain-1 and calpain-2 isoforms are ubiquitously expressed heterodimers composed of isoform specific catalytic subunits coupled with an obligate common regulatory subunit encoded by capns1. Here, we report that conditional deletion of capns1 disrupted calpain-1 and calpain-2 expression and activity, and this was associated with delayed tumorigenesis and altered signaling in a transgenic mouse model of spontaneous HER2+ breast cancer and effectively blocked tumorigenesis in an orthotopic engraftment model. Furthermore, capns1 knockout in a tumor derived cell line correlated with enhanced sensitivity to the chemotherapeutic doxorubicin and the HER2/EGFR tyrosine kinase inhibitor lapatinib. Collectively, these results indicate pro-tumorigenic roles for calpains-1/2 in HER2+ breast cancer and provide evidence that calpain-1/2 inhibitors could have anti-tumor effects if used either alone or in combination with chemotherapeutics and targeted agents.

AB - Colorectal cancer is one of the most common cancers worldwide with high mortality. Distant metastasis and relapse are major causes of patient death. Cancer stem cells (CSCs) play a critical role in the metastasis and relapse of colorectal cancer. CSCs are a subpopulation of cancer cells with unique properties of self-renewal, infinite division and multi-directional differentiation potential. Colorectal CSCs are defined with a group of cell surface markers, such as CD44, CD133, CD24, EpCAM, LGR5 and ALDH. They are highly tumorigenic, chemoresistant and radioresistant and thus are critical in the metastasis and recurrence of colorectal cancer and disease-free survival. This review article updates the colorectal CSCs with a focus on their role in tumor initiation, progression, drug resistance and tumor relapse.

PMID- 30279974 TI - Silicone breast implant associated fibromatosis. AB - Extra-abdominal desmoid tumors, also known as aggressive or deep fibromatosis, are uncommon soft tissue tumors that rarely involve the breast. Although the exact etiology is unknown, the development of these tumors has been correlated with sites of previous trauma, surgery or in association with familial adenomatous polyposis. Clinically, breast fibromatosis is often mistaken for carcinoma but lacks metastatic potential. It is locally aggressive with high rates of recurrence. The treatment is primarily wide local excision with negative margins. Adjuvant treatments have been suggested and include radiotherapy, chemotherapy and hormonal therapy, however, there are no evidence-based treatment protocols to support their use. Here, we describe a case of fibromatosis that developed within the capsule around a silicone breast implant treated with surgical excision alone. The patient remains recurrence free at 3 months post operative magnetic resonance imaging. PMID- 30279971 TI - Inhibition of interleukin-1 receptor-associated kinase 1 (IRAK1) as a therapeutic strategy. AB - Interleukin-1 receptor-associated kinases (IRAK1, IRAK2, IRAK3 [IRAK-M], and IRAK4) are serine-threonine kinases involved in toll-like receptor and interleukin-1 signaling pathways, through which they regulate innate immunity and inflammation. Evidence exists that IRAKs play key roles in the pathophysiologies of cancers, and metabolic and inflammatory diseases, and that IRAK inhibition has potential therapeutic benefits. Molecules capable of selectively interfering with IRAK function and expression have been reported, paving the way for the clinical evaluation of IRAK inhibition. Herein, we focus on IRAK1, review its structure and physiological roles, and summarize emerging data for IRAK1 inhibitors in preclinical and clinical studies. PMID- 30271579 TI - WordCommentsAnalyzer: A windows software tool for qualitative research. AB - There is a lack of free software that provides a professional and smooth experience in text editing and markup for qualitative data analysis. Word processing software like Microsoft Word provides a good editing experience, allowing the researcher to effortlessly add comments to text portions. However, organizing the keywords and categories in the comments can become a more difficult task when the amount of data increases. We present WordCommentsAnalyzer, a software tool that is written in C# using .NET Framework and OpenXml, which helps a qualitative researcher to organize codes when using Microsoft Word as the primary text markup software. WordCommentsAnalyzer provides an effective user interface to count codes, to organize codes in a code hierarchy, and to see various data extracts belonging to each code. It also offers basic visualization tools. We illustrate how to use this software by conducting a preliminary content analysis on Tweets with the #successfulaging hashtag. We also demonstrate that the software has satisfactory performance on a large dataset of Iranian journals abstracts. We hope this open-source software will facilitate qualitative data analysis by researchers who are interested in using Word for this purpose. PMID- 30271571 TI - Patent foramen ovale closure versus medical therapy for stroke prevention: A systematic review and meta-analysis of randomized controlled trials. AB - Background: Previous randomized trials on patent foramen ovale (PFO) closure versus medical therapy for stroke prevention were inconclusive. Recently, two new randomized trials and new findings from an extended follow-up of a previous trial have been published on this topic. We conducted a systematic review and meta analysis of randomized trials comparing PFO closure with medical therapy for stroke prevention. Methods: PubMed and Cochrane Library were searched until 16 th September 2017. The following search terms were used for PubMed: "patent foramen ovale" AND (stroke OR embolism) and "randomized" AND "Trial". For Cochrane Library, the following terms were used: "patent foramen ovale" AND "closure" AND (stroke OR embolism). Results: A total of 91 and 55 entries were retrieved from each database using our search strategy respectively, of which six studies on five trials met the inclusion criteria. This meta-analysis included 1829 patients in the PFO closure arm (mean age: 45.3 years; 54% male) and 1972 patients in the medical therapy arm (mean age: 45.1 years; 51% male). The median follow-up duration was 50 +/- 30 months. When compared to medical therapy, PFO closure significantly reduced primary endpoint events with a risk ratio [RR] of 0.60 (95% CI: 0.44-0.83, P < 0.0001; I 2: 15%). It also reduced stroke (RR: 0.50, 95% CI: 0.35-0.73, P < 0.0001; I 2: 32%) despite increasing the risk of atrial fibrillation/flutter (RR: 1.90, 95% CI: 1.23-2.93, P < 0.01; I 2: 43%). However, it did not reduce transient ischemic accident events (0.75; 95% CI: 0.51-1.10, P = 0.14; I 2: 0%), all-cause bleeding (RR: 0.89; 95% CI: 0.44-1.78, P = 0.74; I 2: 51%) or gastrointestinal complications (RR: 0.92; 95% CI: 0.32-2.70, P = 0.88; I 2: 0%). Conclusions: PFO closure significantly reduces risk of stroke when compared to medical treatment and should therefore be considered for stroke prevention in PFO patients. PMID- 30271581 TI - An opportunity for clinical pharmacology trained physicians to improve patient drug safety: A retrospective analysis of adverse drug reactions in teenagers. AB - Background: Adverse drug reactions (ADRs) are a major cause of hospital admissions, prolonged hospital stays, morbidity, and drug-related mortality. In this study, we sought to identify the most frequently reported medications and associated side effects in adolescent-aged patients in an effort to prioritize clinical pharmacology consultation efforts for hospitals seeking to improve patient safety. Methods: Quarterly reported data were obtained from the United States Food and Drug Administration Adverse Events Reporting System (FAERS) from the third quarter of 2014 and ending in the third quarter of 2017. We then used the GeneCards database to map the pharmacogenomic biomarkers associated with the most reported FAERS drugs. Data homogenization and statistics analysis were all conducted in R for statistical programming. Results: We identified risperidone (10.64%) as the compound with the most reported ADRs from all reported cases. Males represented 90.1% of reported risperidone cases with gynecomastia being the most reported ADR. Ibuprofen OR=188 (95% CI, 105.00 - 335.00) and quetiapine fumarate OR=116 (95% CI, 48.40 - 278.00) were associated with the highest odds of completed suicide in teenagers. Ondansetron hydrochloride OR=7.12 (95% CI, 1.59 - 31.9) resulted in the highest odds of pneumothorax. Lastly, olanzapine (8.96%) represented the compound with the most reported drug-drug interactions cases, while valproic acid OR=221 (95% CI, 93.900 - 522.00) was associated with the highest odds of drug-drug interactions. Conclusion: Despite any data limitations, physicians prescribing risperidone in males should be aware of the high rates of adverse drug events and an alternative psychotropic should be considered in male patients. Further, patients with a history of pneumothorax or genetically predisposed to pneumothorax should be considered for an alternative antiemetic to ondansetron hydrochloride, due to increased odds associated with the drug and adverse event. PMID- 30271582 TI - Clinical application of high frequency jet ventilation in stereotactic liver ablations - a methodological study. AB - Background: Computer-assisted navigation during thermal ablation of liver tumours, may help to correct needle placement and improve ablation efficacy in percutaneous, laparoscopic and open interventions. The potential advantage of using high frequency jet-ventilation technique (HFJV) during the procedure is by minimising the amplitude of respiration-related upper-abdominal organs movements. The aim of this clinical methodological trial was to establish whether HFJV would give less ventilatory induced liver movements than conventional ventilation, during stereotactic navigated ablation of liver metastases under open surgery. Methods: Five consecutive patients scheduled for elective, open liver ablation under general propofol and remifentanil anaesthesia were included in the study protocol. During the stereotactic targeting of the tumours, HFJV was chosen for intraoperative lung ventilation. For tracking of liver movement, a rigid marker shield was placed on the liver surface and tracked with an optical position measurement system. A 4D position of the marker shield was measured for HFJV and conventional tidal volume lung ventilation (TV). At each time point the magnitude of liver displacement was calculated as an Euclidean distance between translational component of the marker shield's 3D position and previously estimated centroid of the translational motion. Results: The mean Euclidean liver displacement was 0.80 (0.10) mm for HFJV and 2,90 (1.03) mm for TV with maximum displacement going as far as 12 mm on standard ventilation (p=0.0001). Conclusion: HFJV is a valuable lung ventilation method for patients undergoing stereotactic surgical procedures in general anaesthesia when reduction of organ displacement is crucial. PMID- 30279980 TI - Computer assisted system for precise lung surgery based on medical image computing and mixed reality. AB - The key of a surgical treatment for the lung cancer is to remove the infected part with the least excision and to retain most of the healthy lung tissue. The traditional computer surgery assisted system show that the patient's CT images or three-dimensional structure in the PC screen. This assisted system is not a real three-dimensional system and can't display well the position of pulmonary vessels and trachea of the patients to surgeon. To solve the problem, a computer assisted system for precise lung surgery for precise surgery based on medical image and VR is developed in this paper. Firstly, the regional growth and filling algorithm is designed to segment lung trachea and lung vessels. Then, the reference edge grid algorithm is used to construct the model of the segmentation trachea and lung vessels. And the models are saved as an identifiable STL type file. Finally, according to the system analysis for the specific system function, the computer assisted system is implemented to display the three-dimensional pulmonary vessels and trachea on the mixed reality device. The surgeons can observe and interface precisely the real three-dimensional lung structure of the patient to help them operate accurately the lung surgery. PMID- 30271584 TI - A systematic performance evaluation of clustering methods for single-cell RNA-seq data. AB - Subpopulation identification, usually via some form of unsupervised clustering, is a fundamental step in the analysis of many single-cell RNA-seq data sets. This has motivated the development and application of a broad range of clustering methods, based on various underlying algorithms. Here, we provide a systematic and extensible performance evaluation of 14 clustering algorithms implemented in R, including both methods developed explicitly for scRNA-seq data and more general-purpose methods. The methods were evaluated using nine publicly available scRNA-seq data sets as well as three simulations with varying degree of cluster separability. The same feature selection approaches were used for all methods, allowing us to focus on the investigation of the performance of the clustering algorithms themselves. We evaluated the ability of recovering known subpopulations, the stability and the run time and scalability of the methods. Additionally, we investigated whether the performance could be improved by generating consensus partitions from multiple individual clustering methods. We found substantial differences in the performance, run time and stability between the methods, with SC3 and Seurat showing the most favorable results. Additionally, we found that consensus clustering typically did not improve the performance compared to the best of the combined methods, but that several of the top-performing methods already perform some type of consensus clustering. All the code used for the evaluation is available on GitHub ( https://github.com/markrobinsonuzh/scRNAseq_clustering_comparison). In addition, an R package providing access to data and clustering results, thereby facilitating inclusion of new methods and data sets, is available from Bioconductor ( https://bioconductor.org/packages/DuoClustering2018). PMID- 30279981 TI - Optimizing spatial healthcare assets with Internet of Things. AB - Six percent of the total cost of healthcare delivery in Australia is from buying, building and maintaining physical assets. Current practice does not measure the efficient use of existing clinical spaces prior to making funding decisions for service expansion, remodeling or relocation. Healthcare service delivery can be increased through existing assets by optimizing the use of clinical space. The wait times for healthcare service consumers and capital expenditure pressures could be reduced, which would result in increased funds available for frontline services. Sensor technology has been used to study aspects of time in ambulatory outpatient clinics using Infra-red Tags or Radio Frequency Identification tags. This paper proposes the use of Internet of Things (IoT) technology to assist in the optimization of high-value clinical spaces and presents phase one of the project where a trial was held in a non-clinical location to evaluate sensor performance. In Phase two, sensors will be installed to count people across an ambulatory outpatient clinic in a live public healthcare environment to understand clinical space utilization and inform decision-makers. The data produced by the sensors on room use is processed for visualization in "dashboard" format so frontline and executive staff have evidence-based decision-making support for space optimization strategies. This paper presents the phase one trial and preliminary results that show the disparity space utilization patterns between the IoT sensed occupancy data with the current room reservation system in a non-clinical space. PMID- 30279982 TI - Emotion classification using flexible analytic wavelet transform for electroencephalogram signals. AB - Emotion based brain computer system finds applications for impaired people to communicate with surroundings. In this paper, electroencephalogram (EEG) database of four emotions (happy, fear, sad, and relax) is recorded and flexible analytic wavelet transform (FAWT) is proposed for the emotion classification. FAWT analyzes the EEG signal into sub-bands and statistical measures are computed from the sub-bands for extraction of emotion specific information. The emotion classification performance of sub-band wise extracted features is examined over the variants of k-nearest-neighbor (KNN) classifier. The weighted-KNN provides the best emotion classification performance 86.1% as compared to other KNN variants. The proposed method shows better emotion classification performance as compared to other existing four emotions classification methods. PMID- 30279983 TI - Features based on variational mode decomposition for identification of neuromuscular disorder using EMG signals. AB - Neuromuscular disorder is a muscular and nervous disorder resulting in muscular weakness and progressively damages nervous control, such as amyotrophic lateral sclerosis (ALS) and myopathy (MYO). Its diagnosis can be possible by classification of ALS, MYO, and normal electromyogram (EMG) signals. In this paper, an effective method based on variational mode decomposition (VMD) is proposed for identification of neuromuscular disorder of EMG signals. VMD is an adaptive signal decomposition which decomposes EMG signals nonrecursively into band-limited functions or modes. These modes are used for extraction of spectral features, particularly spectral flatness, spectral spread, spectral decrease and statistical features like kurtosis, mean absolute deviation, and interquartile range. The extracted features are fed to the extreme learning machine classifier in order to classify neuromuscular disorder of EMG signals. The performance of obtained results shows that the method used provides a better classification for neuromuscular disorder of EMG signals as compared to existing methods. PMID- 30279985 TI - Survey of energy drink consumption and adverse health effects in Lebanon. AB - Consumption of energy is a national and international phenomenon that showed increase in market spread and profits from 1990 and made the emergence of many brands. Energy drinks are aggressively marketed with the claim that these products give an energy boost to improve physical and cognitive performance. However, studies supporting these claims are limited. The study examines the new phenomena of energy drinks among university students in Lebanon, based on the participants' personnel characteristics, university grade and the impact on health status. The study also determined whether high frequency of consumption was correlated with negative physical health symptoms. A cross-sectional study survey was undertaken on students aged between 18 and 30 years in private university over three branches (Beirut, Tripoli and Saida). A self-administered questionnaire was used inquiring about socio-demographic characteristics, consumption patterns and side effect of energy drinks. Data was analyzed using SPSS 24. Findings showed a serious concern exists for the health and safety of the most at risk students who engaged in daily energy drink usage when two-thirds of these reported difficulties sleeping, more than one experienced heart palpitation and blood pressure; one-third had anxiety, nervousness and feeling thirsty, and one fifth indicated tiredness and headache. Such symptoms are reported with excessive consumption of caffeine that had adverse health effect on the body.

Analytics over data streams from IoT has become a source of user data for the healthcare systems to discover new information, predict early detection, and makes decision over the critical situation for the improvement of the quality of life. In this paper, we have made a detailed study on the recent emerging technologies in the personalized healthcare systems with the focus towards cloud computing, fog computing, Big Data analytics, IoT and mobile based applications. We have analyzed the challenges in designing a better healthcare system to make early detection and diagnosis of diseases and discussed the possible solutions while providing e health services in secure manner. This paper poses a light on the rapidly growing needs of the better healthcare systems in real-time and provides possible future work guidelines. PMID- 30279987 TI - Evolution of blood pressure control identification in lieu of post-surgery diabetic patients: a review. AB - The blood pressure disparity is the major problem in post-operative surgery especially diabetic patients, because there is substantial interrelation between diabetic and hypertension and this abnormality creates complicated problems and needs to be controlled by continuous monitoring based on the severity. To overcome this problem, implementation of automatic drug infusion is required for critical patients, by which workload of the clinical staffs are reduced. Most commonly the sodium nitroprusside (SNP) is used to reduce the blood pressure in fast action based on the prescribed level. In this paper three different types of estimation techniques (PID, IMC and MPC) are uses to identify the valuation. The strength of the projected controller performance is evaluated under different types of patients such as sensitive, and normal along with insensitive patients. Therefore, this paper review the validation results based on the optimized SNP infusion rate for persistent Blood pressure control compare then the reviewed methods. The MATLAB simulation is used to evaluate the efficiency of the proposed work and obtain the results based on the projected values. PMID- 30279986 TI - Cloud based framework for diagnosis of diabetes mellitus using K-means clustering. AB - Diabetes mellitus is a serious health problem affecting the entire population all over the world for many decades. It is a group of metabolic disorder characterized by chronic disease which occurs due to high blood sugar, unhealthy foods, lack of physical activity and also hereditary. The sorts of diabetes mellitus are type1, type2 and gestational diabetes. The type1 appears during childhood and type2 diabetes develop at any age, mostly affects older than 40. The gestational diabetes occurs for pregnant women. According to the statistical report of WHO 79% of deaths occurred in people under the age of 60, due to diabetes. With a specific end goal to deal with the vast volume, speed, assortment, veracity and estimation of information a scalable environment is needed. Cloud computing is an interesting computing model suitable for accommodating huge volume of dynamic data. To overcome the data handling problems this work focused on Hadoop framework along with clustering technique. This work also predicts the occurrence of diabetes under various circumstances which is more useful for the human. This paper also compares the efficiency of two different clustering techniques suitable for the environment. The predicted result is used to diagnose which age group and gender are mostly affected by diabetes. Further some of the attributes such as hyper tension and work nature are also taken into consideration for analysis.

Many breast cancer patients die every year due to the late diagnosis and treatment. Thus, in recent years, early breast cancer detection systems based on patient's imagery are in demand. Deep learning attracts many researchers recently and many computer vision applications have come out in various environments. Convolutional neural network (CNN) which is known as deep learning architecture, has achieved impressive results in many applications. CNNs generally suffer from tuning a huge number of parameters which bring a great amount of complexity to the system. In addition, the initialization of the weights of the CNN is another handicap that needs to be handle carefully. In this paper, transfer learning and deep feature extraction methods are used which adapt a pre-trained CNN model to the problem at hand. AlexNet and Vgg16 models are considered in the presented work for feature extraction and AlexNet is used for further fine-tuning. The obtained features are then classified by support vector machines (SVM). Extensive experiments on a publicly available histopathologic breast cancer dataset are carried out and the accuracy scores are calculated for performance evaluation. The evaluation results show that the transfer learning produced better result than deep feature extraction and SVM classification. PMID- 30279989 TI - Clinical factors affecting perioperative outcomes in robot-assisted radical prostatectomy. AB - The present study investigated clinical factors affecting perioperative outcomes in robot-assisted radical prostatectomy (RARP). The study included 625 Japanese cases treated with RARP between 2009 and 2017. The association between clinical factors (age, overweight status, prostate volume, clinical T-stage, nerve sparing, lympho-node dissection, and the number of experienced cases) and perioperative outcomes (operation time, estimated blood loss, catheterization duration, and perioperative complication) were analyzed. Results revealed that overweight status, prostate volume, lymph-node dissection, and the number of experienced cases were associated with operation time. For estimated blood loss, the identified risk factors were overweight status, prostate volume, nerve sparing, lymph-node dissection, and the number of experienced cases. Lymph-node dissection and the number of experienced cases were also associated with catheterization duration. Additionally, only lymph-node dissection was associated with increased perioperative complication. Taken together, the present study identified several clinical factors affecting perioperative outcomes in RARP. This information may help surgeons to estimate perioperative outcomes as well as to inform patients. PMID- 30279990 TI - Suppression of LOX activity enhanced seed vigour and longevity of tobacco (Nicotiana tabacum L.) seeds during storage. AB - The preservation of seed viability and quality in storage is an important trait both for commercial and germplasm usage. To better explore potential mechanisms of tobacco seed deterioration, seed packed in cloth bag (C) and vacuum bag (V) were stored under room temperature (RT) and low temperature (LT, 18 degrees C), and sampled periodically for laboratory testing. Seed stored in low temperature with vacuum bag (LT/V) owned the highest seed vigour after 25 months of storage and in room temperature with cloth bag (RT/C) lost seed vigour and germination ability after 20-month storage. Meanwhile, seed in RT/C notably increased about 5 fold endogenous hydrogen peroxide (H2O2), 4-fold malondialdehyde (MDA) contents, 12-fold Lipoxygenases (LOX) activity and 2-fold the expression of NtLOX3 comparing with LT/V at the end of 15-month storage. In addition, regression analysis indicated that LOX activity was strongly negatively correlated with seed vigour as the R 2 value reached 0.970 in RT/C. Furthermore, caffeic acid and catechin, the inhibitors of LOX activity, were applied to tobacco seeds pre treatment and followed with artificial accelerated aging. Seeds pretreated with inhibitors, especially caffeic acid, reduced LOX activity by 50%, MDA and H2O2 contents by 40% and 20%, respectively, and increased more than 1.2-fold seed vigour and seedling quality comparing with seeds pretreated with H2O after 6-day artificial aging, indicating a better seed storability after artificial accelerated aging. These results suggest that LOX accelerated seed aging, and suppression of LOX activity enhanced seed vigour and viability in accelerated aging tobacco seed, opening new opportunities for effective management of seed germplasm under long-term storage and conservation. PMID- 30279991 TI - Integrating physiological stress into the movement ecology of migratory ungulates: a spatial analysis with mule deer. AB - Rapid climate and human land-use change may limit the ability of long-distance migratory herbivores to optimally track or 'surf' high-quality forage during spring green-up. Understanding how anthropogenic and environmental stressors influence migratory movements is of critical importance because of their potential to cause a mismatch between the timing of animal movements and the emergence of high-quality forage. We measured stress hormones (fecal glucocorticoid metabolites; FGMs) to test hypotheses about the effects of high quality forage tracking, human land-use and use of stopover sites on the physiological state of individuals along a migratory route. We collected and analysed FGM concentrations from 399 mule deer (Odocoileus hemionus) samples obtained along a 241-km migratory route in western Wyoming, USA, during spring 2015 and 2016. In support of a fitness benefit hypothesis, individuals occupying areas closer to peak forage quality had decreased FGM levels. Specifically, for every 10-day interval closer to peak forage quality, we observed a 7% decrease in FGMs. Additionally, we observed support for both an additive anthropogenic stress hypothesis and a hypothesis that stopovers act as physiological refugia, wherein individuals sampled far from stopover sites exhibited 341% higher FGM levels if in areas of low landscape integrity compared to areas of high landscape integrity. Overall, our findings indicate that the physiological state of mule deer during migration is influenced by both anthropogenic disturbances and their ability to track high-quality forage. The availability of stopovers, however, modulates physiological responses to those stressors. Thus, our results support a recent call for the prioritization of stopover locations and connectivity between those locations in conservation planning for migratory large herbivores. PMID- 30279992 TI - Assay validation and interspecific comparison of salivary glucocorticoids in three amphibian species. AB - Amphibians are one of the most threatened groups of species, facing stressors ranging from habitat degradation and pollution to disease and overexploitation. Stress hormones (glucocorticoids, GCs) provide one quantitative metric of stress, and developing non-invasive methods for measuring GCs in amphibians would clarify how diverse environmental stressors impact individual health in this taxonomic group. Saliva is an advantageous matrix for quantifying GCs, as it is sampled less invasively than plasma while still detecting both baseline and acute elevation of GCs within a short timeframe. Little work has employed this method in amphibian species, and it has never been pharmacologically and biologically validated. Here, we conduct analytical, pharmacological and biological validation experiments for measuring salivary corticosterone in three amphibian species: the American bullfrog (Rana catesbeiana), the green frog (Rana clamitans) and the northern leopard frog (Rana pipiens). These species are faced with a broad range of environmental challenges, and in part of its range R. pipiens populations are currently in decline. In addition to demonstrating that this method can be reliably used in multiple amphibian species, we present an examination of intrinsic biological factors (sex, body condition) that may contribute to GC secretion, and a demonstration that saliva can be collected from free-living animals in the field to quantify corticosterone. Our findings suggest that saliva may be useful for less invasively quantifying GCs in many amphibian species. PMID- 30279993 TI - Lipoma in dogs under primary veterinary care in the UK: prevalence and breed associations. AB - Background: Lipomas are masses of mesenchymal origin, comprising of adipocytes, and are often clinically unremarkable but can be alarming to owners. Although lipomas are reportedly common in dogs, no studies have specifically investigated risk factors associated with their occurrence. This study was a large-scale retrospective analysis of electronic patient records of dogs attending practices participating in VetCompassTM. Univariable and multivariable logistic regression methods were used to evaluate associations between risk factors and primary-care veterinary diagnosis of lipoma. Results: From 384,284 dogs under veterinary care during 2013 at 215 primary practice clinics in the UK, there were 2765 lipoma cases identified giving a one-year prevalence of 1.94% (95% CI: 1.87-2.01). Breeds with the highest lipoma prevalence included Weimaraner (7.84%, 95% CI 6.46 9.40), Dobermann Pinscher (6.96%, 95% CI 5.67-8.44), German Pointer (5.23%, 95% CI 3.93-6.80), Springer Spaniel (5.19%, 95% CI 4.76-5.66), and Labrador Retriever (5.15%, 95% CI 4.90-5.41). Dogs with an adult bodyweight equal or higher than their breed/sex mean had 1.96 (95% CI 1.81-2.14, P < 0.001) times the odds of lipoma compared with dogs that weighed below their breed/sex mean. The odds of lipoma increased as adult bodyweight increased. Increased age was strongly associated with increasing odds of lipoma. Compared with dogs aged 3.0 to < 6.0 years, dogs aged 9.0 - < 12.0 years had 17.52 times the odds (95% CI 14.71-20.85, P < 0.001) of lipoma. Neutered males (OR: 1.99, 95% CI 1.69-2.36, P < 0.001) and neutered females (OR: 1.62, 95% CI 1.37-1.91, P < 0.001) had higher odds than entire females. Insured dogs had 1.78 (95% CI 1.53-2.07, P < 0.001) times the odds of lipoma compared with uninsured dogs. Conclusions: Lipomas appear to be a relatively common diagnosis in primary-care practice. Certain breeds were identified with remarkably high lipoma prevalence, highlighting the risk that owners should be prepared for. Lipoma predisposition of larger bodyweight individuals within breed/sex suggests that being overweight or obese may be a predisposing factor but would need further work to confirm. PMID- 30279994 TI - Diagnosis and management of a heterotopic pregnancy and ruptured rudimentary uterine horn. AB - Background: Heterotopic pregnancies implanted in a rudimentary uterine horn account for 1 in 2-3 million gestations, and confer significant risk of morbidity due to uterine rupture and hemorrhage. Case presentation: A 34-year-old nullipara presented with acute pelvic pain at 17 weeks of gestation with dichorionic diamniotic twins, one in each horn of an anomalous uterus first diagnosed in pregnancy as bicornuate. Three-dimensional ultrasound and MRI revealed myometrial disruption in the left rudimentary uterine horn, and the patient underwent an uncomplicated abdominal hemi-hysterectomy. Fourteen days later, an uncomplicated dilation and curettage was performed for a fetal anomaly in the remaining twin in the right unicornuate uterus. Conclusion: This case demonstrates the utility of magnetic resonance imaging and three-dimensional ultrasound in the assessment of myometrial integrity in a gravid patient with a heterotopic pregnancy and ruptured rudimentary uterine horn. This case demonstrates the importance of pre pregnancy diagnosis and management of mullerian anomalies. PMID- 30279995 TI - Flexible Bronchoscopy Under Bronchoscopist-Administered Moderate Sedation Versus General Anesthesia: A Comparative Study in Children. AB - Background: Flexible bronchoscopy (FB) can be performed under bronchoscopist administered moderate sedation (BAMS) with a midazolam/fentanyl combination or general anesthesia (GA). However, the outcome of BAMS has not been well established in children. Currently, most of the centers prefer FB under GA. Both techniques have their advantages and disadvantages with implications for safety, complications, and diagnostic yield. The primary objective of our study was to evaluate the safety, time efficiency, and cost-effectiveness of FB under BAMS as compared with FB under GA in a similar setting. Methods: We performed a retrospective chart review to compare BAMS versus GA for FB in children. We recruited BAMS children (n = 295) from University of Florida (UF) Health Shands Children's Hospital, and GA children (n = 100) from Penn State Children's Hospital (PSHCH). Both the groups had similar indications, complexities, and procedural environments. Comparisons of various time-intervals including preprocedure time, sedation-induction time, scope time, and post-procedure time among different BAMS versus GA age-groups were the primary outcomes. The secondary outcomes were the determination of the rates of complications, the dosages of sedative/anesthetic, cost-effectiveness, and sedation patterns under BAMS. Results: FB under BAMS required significantly higher preprocedure times and sedation-induction times (P < 0.001** and P < 0.001** respectively) but shorter scope and post-procedure times compared with the GA group times (P < 0.001** and P < 0.001** respectively). Younger children had a deeper level of sedation for an extended period under BAMS. The costs for the sedation services and the complication rates were lower in the BAMS group compared with the GA group. Conclusion: Our study demonstrated the feasibility of BAMS in children. FB under BAMS had an advantage of lower cost and fewer procedural complications compared with FB under GA. Despite that, the safety of BAMS could not be conclusively established from this retrospective study. Moreover, BAMS can potentially compromise the diagnostic yield because the bronchoscopist is also responsible for monitoring sedation and managing the airway. PMID- 30279996 TI - Recent Trends in Unpasteurized Fluid Milk Outbreaks, Legalization, and Consumption in the United States. AB - INTRODUCTION: Determining the potential risk of foodborne illness has become critical for informing policy decisions, due to the increasing availability and popularity of unpasteurized (raw) milk. METHODS: Trends in foodborne illnesses reported to the Centers for Disease Control in the United States from 2005 to 2016 were analyzed, with comparison to state legal status and to consumption, as estimated by licensing records. RESULTS: The rate of unpasteurized milk associated outbreaks has been declining since 2010, despite increasing legal distribution. Controlling for growth in population and consumption, the outbreak rate has effectively decreased by 74% since 2005. DISCUSSION: Studies of the role of on-farm food safety programs to promote the further reduction of unpasteurized milk outbreaks should be initiated, to investigate the efficacy of such risk management tools. PMID- 30279997 TI - Removal of the Mitochondrial Fission Factor Mff Exacerbates Neuronal Loss and Neurological Phenotypes in a Huntington's Disease Mouse Model. AB - OBJECTIVE: Excessive mitochondrial fission has been associated with several neurodegenerative diseases, including Huntington's disease (HD). Consequently, mitochondrial dynamics has been suggested to be a promising therapeutic target for Huntington's disease. Mitochondrial fission depends on recruitment of Drp1 to mitochondria, and Mff (mitochondrial fission factor) is one of the key adaptor proteins for this process. Removal of Mff therefore greatly reduces mitochondrial fission. Here we investigate whether removal of Mff can mitigate HD-associated pathologies in HD transgenic mice (R6/2) expressing mutant Htt. METHOD: We compared the phenotype of HD mice with and without Mff. The mice were monitored for lifespan, neurological phenotypes, Htt aggregate formation, and brain histology. RESULTS: We found that HD mice lacking Mff display more severe neurological phenotypes and have shortened lifespans. Loss of Mff does not affect mutant Htt aggregation, but it accelerates HD pathology, including neuronal loss and neuroinflammation. CONCLUSIONS: Our data indicate a protective role for mitochondrial fission in HD and suggest that more studies are needed before manipulation of mitochondrial dynamics can be applied to HD therapy. PMID- 30279998 TI - Comparison of Green Versus Blue Fundus Autofluorescence in ABCA4-Related Retinopathy. AB - Purpose: To investigate the interreader and intermodality agreement for grading of retinal pigment epithelium (RPE) atrophy lesion size in ABCA4-related retinopathy using green (GAF) and blue fundus autofluorescence (BAF) imaging. Methods: In this cross-sectional case series, 97 eyes of 49 patients with RPE atrophy secondary to ABCA4-related retinopathy underwent GAF- (518 nm excitation light) and BAF- (488 nm excitation light) imaging using confocal scanning laser ophthalmoscopy (Spectralis HRA, Heidelberg Engineering, Heidelberg, Germany). Lesions with definitely decreased autofluorescence (DDAF) and questionably decreased autofluorescence (QDAF) in GAF and BAF imaging were analyzed separately by five independent readers using semiautomated software (RegionFinder, Heidelberg Engineering). Intermodality and interreader agreements were assessed for the square-root lesion size, lesion perimeter, and circularity. Results: GAF- and BAF-based measurements of DDAF and QDAF showed high intermodality and interreader agreement concerning square-root lesion size, as well as shape descriptive parameters (perimeter and circularity). Interreader agreement of square-root lesion size was slightly, hence not significantly higher for GAF based grading ([95% coefficients of repeatability, intraclass correlation coefficient] DDAF: 0.215 mm, 0.997; QDAF: 0.712 mm, 0.981) compared to BAF-based grading (DDAF: 0.232 mm, 0.997; QDAF: 0.764 mm, 0.978). However, DDAF measurements revealed distinctly more reproducible results than QDAF measurements. Foveal sparing did not interfere with intermodality agreement. Conclusions: Both GAF- and BAF-based quantification of RPE atrophy showed very reliable results with possible superiority of GAF in the context of less energetic excitation light. Translational Relevance: The high interreader agreement qualifies the use of DDAF progression in GAF and BAF imaging as potential morphologic outcome measure for interventional clinical trials and disease monitoring. PMID- 30279999 TI - Development and Validation of the Singapore Thyroid Eye Disease Quality of Life Questionnaire. AB - Purpose: Current instruments to assess thyroid eye disease (TED) quality of life (QoL) were not developed using modern psychometric theory and may not be applicable to Asian populations. Therefore, we developed a psychometrically robust questionnaire, the Singapore Thyroid Eye Disease Quality of Life questionnaire (STED-QoL), for assessing QoL in Asian patients. Methods: This cross-sectional study was conducted at the Singapore National Eye Centre between 2012 and 2015. In Phase 1, content for the questionnaire was developed using qualitative methods. A total of 20 patients participated in three different focus groups. Thematic analysis was conducted to identify relevant themes from which 12 items, rated on a 5-point Likert-type scale, were generated. In Phase 2, the pilot instrument was administered to 59 TED patients and psychometric assessment of the STED-QoL was conducted using Rasch analysis. Results: After collapsing categories from five to four and deleting two misfitting items, we generated a 10 item STED-QoL befitting the Rasch model. The scale showed good criterion validity, with scores decreasing as severity of TED worsened: mild (1.78 logits), moderate (0.27 logits), and severe (0.92 logits). A 'Psychosocial' subscale also had adequate psychometric properties and psychosocial scores were significantly worse in those who underwent surgery for TED compared to those who had not (0.41 vs. 1.82 logits, P = 0.021). Conclusions: The STED-QoL is a robust 10-item questionnaire specifically developed to measure the impact of TED on QoL and psychosocial well-being in an Asian population. Translational Relevance: QoL assessment is important for holistic management of TED patients. PMID- 30280000 TI - Functional Staging of Corneal Neovascularization Using Fluorescein and Indocyanine Green Angiography. AB - Purpose: Corneal neovascularization (CoNV) is a major risk factor for corneal graft rejection and other corneal conditions. The maturity of CoNV is important to guide treatment. This study investigated associations between clinical and angiographic characteristics of CoNV. Methods: In a prospective cross-sectional study patients with CoNV of variable but known duration and etiology were included. All cases were clinically staged according to a simplified three-grade scale as active, inactive, and regressed and assessed using color photography, anterior-segment optical coherence tomography, and fluorescein and indocyanine green (ICG) angiography. Outcome parameters included age and depth of CoNV, perfusion times and time to leakage of fluorescein and ICG. Results: Forty eyes of 39 patients with CoNV were included, active (14), inactive (22), and regressed CoNV (4). There were significant associations between the time to fluorescein or ICG leakage and clinical staging of CoNV (R 2 = 0.24; P = 0.0011, and R 2 = 0.3; P = 0.0001). In addition, there was a significant association between the time to fluorescein leakage and the age of CoNV (R 2 = 0.32; P = 0.0002). ICG leakage within 10 minutes was observed significantly more frequently in active than the inactive group and was not observed in regressed cases (P < 0.0001). Conclusions: Simplification of the staging of CoNV to active, inactive, and regressed to is significantly associated with the time to extravascular leakage of fluorescein and indocyanine and may be useful to guide the selection of appropriate treatments. Translational Relevance: The association between clinical and angiographic characteristics of CoNV may provide guidance to the treatment approaches. PMID- 30280001 TI - Measurable Range of Subfoveal Choroidal Thickness With Conventional Spectral Domain Optical Coherence Tomography. AB - Purpose: We investigate the measurable range of subfoveal choroidal thickness (SFCT) with conventional spectral domain optical coherence tomography (SD-OCT) in normal healthy eyes. Methods: All subjects underwent an SD-OCT horizontal line scan centered at the fovea with standard and enhanced depth imaging (EDI) techniques. Two independent observers manually measured SFCT on standard and EDI OCT images, if two choroidal borders were identified. The rate of successful measurement with standard OCT was evaluated. Inter- and intraclass correlation coefficients and Bland-Altman plots were used for analysis. Results: OCT images of 724 normal healthy eyes from 374 subjects were evaluated. Although the inner choroidal border was identified on all OCT images, the outer choroidal border was identified on 378 of 724 (52.2%) conventional OCT images. Mean SFCT of all study eyes measured by EDI-OCT images was 292.6 +/- 94.0. The number of successful measurements with conventional OCT was 100%, 87.5%, 48.1%, 33.0%, and 0%, in the SFCT ranges of <241, 241-280, 281-320, 321-360, and >360 MUm, respectively. The accumulated rate of successful measurement with conventional OCT was 100%, 96.4%, and 82.2% in the SFCT ranges of <=240, <=280, and <=320 MUm, respectively. Two protocols showed good inter-correlation of SFCT, when SFCT were measurable in both scans. Conclusions: SFCT can be measured by conventional OCT in eyes with thin choroid, and the measured value shows high agreement with those measured by EDI-OCT. In such eyes, conventional OCT can be used potentially to evaluate the retina and choroid. Translational Relevance: In eyes with a thin choroid, conventional OCT can be used potentially to evaluate the retina and choroid with high agreement with EDI-OCT. PMID- 30280002 TI - A Comparative Analysis of the Fear of Falling Between Glaucoma and Age-Related Macular Degeneration Patients From a Developing Country. AB - Purpose: Falls are very prevalent in the older population. Visually impaired elderly patients are prone to falls as the result of visual loss and ageing. The purpose of the study was to compare the fear of falling (FoF) between primary open angle glaucoma (POAG) and age-related macular degeneration (ARMD) patients who live in a developing country. Methods: This was a cross-sectional observational study. After a complete eye examination including measurement of best-corrected visual acuity, ophthalmoscopy, and automated visual field, all subjects completed the Fall Efficacy Scale International Brazil (FES-I-Brazil) questionnaire. Results: The sample comprised 64 patients with POAG, 48 with ARMD, and 52 controls. All groups were matched for age, sex, comorbidity, and ethnic distribution. The FES-I score was 24.6 +/- 8.7, 25.3 +/- 6.3, and 24.2 +/- 7.7 for glaucoma, ARMD, and controls, respectively (P = 0.894). A post hoc analysis comparing all subjects with advanced visual field defect (mean deviation [MD] < 12 dB) revealed a higher FES-I score in ARMD patients as compared to POAG ones (46.2 +/- 16.8 and 24.0 +/- 7.7 for ARMD and POAG, respectively, P < 0.001). Conclusion: In this cohort of elderly subjects with eye diseases, the FoF was similar among groups; however, ARMD patients with more compromised visual field had higher FoF as compared to POAG patients and controls. Translational Relevance: A high rate of fear of falling exists in ARMD patients with compromised visual field. This finding may be useful in developing multidimensional strategies to decrease fear of falling and improve quality of life in older persons living in a developing country. PMID- 30280003 TI - Effect of Ultrasonic Moisture Glasses on Dry Eye Signs and Symptoms. AB - Purpose: This study was undertaken to evaluate the effect of a novel humidifying eyeglass-shaped device-ultrasonic moisture glasses-on dry eye signs and symptoms. Methods: A total of 18 subjects with dry eye symptoms underwent a crossover test. A water cartridge was set on each temple of the eyeglass-shaped device. All subjects randomly wore the device twice in different settings, each for 10 minutes. Subjects wore the glasses once with the cartridges filled with water (the intervention group), and once with the cartridges empty (the control group). The order was randomized. We evaluated tear film break-up time (TBUT) and fluorescein staining score just before, immediately after, and 10 minutes after wearing the device. We also assessed functional visual acuity (FVA), blink frequency, and visual analog scale (VAS) score just before and immediately after wearing the device. Results: TBUT, blink frequency, and VAS improved in the intervention group (all P < 0.001) and exhibited significant differences between the intervention and control groups. Conclusions: Wearing the ultrasonic moisture glasses for 10 minutes improved tear stability and decreased dry eye symptoms in this cohort of subjects. Translational Relevance: These findings show that the ultrasonic moisture glasses are an effective device for improving dry eye signs and symptoms. PMID- 30280004 TI - Prevalence of Subclinical CNV and Choriocapillaris Nonperfusion in Fellow Eyes of Unilateral Exudative AMD on OCT Angiography. AB - Purpose: To determine the prevalence of subclinical choroidal neovascularization (CNV) in fellow eyes of patients with unilateral exudative age-related macular degeneration (AMD) using optical coherence tomography angiography (OCTA) and to quantify choriocapillaris nonperfusion adjacent to CNV. Methods: We retrospectively reviewed all patients with AMD who underwent OCTA and identified eyes with unilateral exudative AMD. We determined the presence of subclinical CNV on custom en face macular slabs of the outer retina and choriocapillaris and confirmed on cross-sectional scans. Two graders quantified the percent choriocapillaris area of nonperfusion (PCAN) in the entire choriocapillaris slab as well as in the "halo" zone (200 MUm) surrounding subclinical and exudative CNV lesions. Results: Of 140 AMD patients who underwent OCTA, 34 had unilateral exudative AMD, with five of the 34 fellow eyes (14.7%) having subclinical CNV. Compared with PCAN in the entire slab (10.333 +/- 4.288%), we found that "halo" PCAN, surrounding CNV, was significantly higher (13.045 +/- 5.809%; P < 0.001). Further, there was a trend for higher PCAN in exudative CNV eyes (15.267 +/- 7.230%) compared with their fellow subclinical CNV eyes (10.823 +/- 3.365%, P = 0.115). Conclusions: There is a notable prevalence of subclinical CNV in fellow eyes with unilateral exudative CNV, and significantly greater choriocapillaris nonperfusion adjacent to all CNV lesions. We identified a trend for increased choriocapillaris nonperfusion in exudative AMD eyes as compared with their fellow subclinical CNV eyes, which deserves further study. Translational Relevance: OCTA can be useful in clinical practice to detect subclinical CNV and study choriocapillaris dysfunction. PMID- 30280005 TI - Variability of Foveal Avascular Zone Metrics Derived From Optical Coherence Tomography Angiography Images. AB - Purpose: To characterize sources of inter- and intrasubject variability in quantitative foveal avascular zone (FAZ) metrics. Methods: Two 3*3-mm optical coherence tomography angiography scans (centered on the fovea) were acquired in both eyes of 175 subjects. An image of the superficial plexus was extracted from each scan and segmented twice by a single observer. Four quantitative FAZ morphology metrics (area, axis ratio, acircularity, major horizontal axis angle) were calculated, and a variance components analysis was performed. Results: Mean (+/-SD) age was 27.9 +/- 11.9 years, and 55% were female. Area had the largest amount of variance resulting from intersubject differences (93.1%). In contrast, there was large interocular variance for axis ratio, acircularity, and major horizontal axis angle (55.0%, 53.7%, 70.7%, respectively), though only axis ratio showed significant asymmetry between fellow eyes (P < 0.05). Neither repeated images from the same eye nor repeated segmentation on the same image were significant sources of variance. Conclusions: Metrics of FAZ morphology show excellent repeatability and reliability. Excluding FAZ area, there was a high amount of variance attributed to interocular differences for the other FAZ metrics; therefore, the fellow eye should not be considered a control for FAZ studies when using these metrics. Translational Relevance: Vision scientists must be prudent when choosing FAZ metrics, as they display varying degrees of within subject differences relative to between-subject differences. It seems likely that different metrics will be best suited for different tasks, such as monitoring small changes over time within a single subject or assessing whether a given FAZ is abnormal. PMID- 30280006 TI - A Smartphone-Based Tool for Rapid, Portable, and Automated Wide-Field Retinal Imaging. AB - Purpose: High-quality, wide-field retinal imaging is a valuable method for screening preventable, vision-threatening diseases of the retina. Smartphone based retinal cameras hold promise for increasing access to retinal imaging, but variable image quality and restricted field of view can limit their utility. We developed and clinically tested a smartphone-based system that addresses these challenges with automation-assisted imaging. Methods: The system was designed to improve smartphone retinal imaging by combining automated fixation guidance, photomontage, and multicolored illumination with optimized optics, user-tested ergonomics, and touch-screen interface. System performance was evaluated from images of ophthalmic patients taken by nonophthalmic personnel. Two masked ophthalmologists evaluated images for abnormalities and disease severity. Results: The system automatically generated 100 degrees retinal photomontages from five overlapping images in under 1 minute at full resolution (52.3 pixels per retinal degree) fully on-phone, revealing numerous retinal abnormalities. Feasibility of the system for diabetic retinopathy (DR) screening using the retinal photomontages was performed in 71 diabetics by masked graders. DR grade matched perfectly with dilated clinical examination in 55.1% of eyes and within 1 severity level for 85.2% of eyes. For referral-warranted DR, average sensitivity was 93.3% and specificity 56.8%. Conclusions: Automation-assisted imaging produced high-quality, wide-field retinal images that demonstrate the potential of smartphone-based retinal cameras to be used for retinal disease screening. Translational Relevance: Enhancement of smartphone-based retinal imaging through automation and software intelligence holds great promise for increasing the accessibility of retinal screening.

AB - [This corrects the article DOI: 10.7717/peerj.3269.]. PMID- 30280007 TI - Differences in Static and Kinetic Perimetry Results are Eliminated in Retinal Disease when Psychophysical Procedures are Equated. AB - Purpose: We tested the hypothesis that clinical statokinetic dissociation (SKD, defined as the difference in sensitivity to static and kinetic stimuli) at the scotoma border in retinal disease is due to individual criterion bias and that SKD can be eliminated by equating the psychophysical procedures for testing static and kinetic stimulus detection. Methods: Six subjects with glaucoma and six with retinitis pigmentosa (RP) were tested. Clinical procedures (standard automated perimetry [SAP] and manual kinetic perimetry [MKP]) were used to determine clinical SKD and the region of interest for laboratory-based testing. Two-way Method of Limits (MoL) was used to establish the isocontrast region at the scotoma border in glaucoma and RP subjects. Method of Constant Stimuli (MoCS) and a two-interval forced choice (2IFC) procedure then were used to present static or kinetic (inward or outward) stimuli at different eccentricities within the isocontrast region. The results were fitted with psychometric functions to determine threshold eccentricities. Results: Clinical SKD was found in glaucoma and RP subjects, with variable magnitude among subjects, but significantly exceeding expected typical measurement variability. The resultant psychometric functions when using MoCS and 2IFC showed equal sensitivity to static and kinetic targets, thus eliminating SKD. Conclusions: Clinical SKD found using clinical techniques is due to methodologic differences and criterion bias, and is eliminated by using an equated and more objective psychophysical task, similar to normal subjects. Translational relevance: Eliminating SKD using a psychophysical approach minimizing criterion bias suggests that it is not useful to distinguish between normal and diseased fields.

AB - Background: Experiencing an adequate amount of cold temperatures over winter is necessary for many temperate tree species to break dormancy and flower in spring. Thus, changes in winter and spring temperatures associated with climate change may influence when trees break dormancy and flower in the future. There have been several experimental studies that have quantified the effectiveness of cold temperatures for chilling requirements for vegetative budburst of temperate trees; however, there are few experimental studies addressing the chilling requirements for reproductive budburst of trees, as it is difficult to place reproductively mature trees in temperature-controlled environments. Methods: To identify how changing temperatures associated with climate change may impact reproductive phenology, we completed a temperature-controlled growth chamber experiment using cuttings of reproductive branches of red alder (Alnus rubra), one of the most widespread hardwood tree species of the Pacific Northwest, USA. The purpose of this study was to examine how colder (4 degrees C) and warmer (9 degrees C) winter temperature regimes influenced the timing of reproductive budburst of red alder cuttings in spring. We also compared the date of budburst of cuttings to that of branches from intact trees. Results: We found that cuttings flowered earlier after pretreatment with a 4 degrees C winter temperature regime than after a 9 degrees C winter temperature regime. We found no significant differences between the timing of male budburst of cuttings exposed to ambient conditions compared to male budburst of branches from intact trees. We used our experimental data to estimate a "possibility-line" that shows the accumulated chilling and forcing temperatures necessary prior to reproductive budburst of red alder. Discussion: This study provides a preliminary indication that warmer winters with climate change may not be as effective as colder winters for satisfying chilling temperature requirements of a Northwest hardwood tree species.

AB - The stem odontocete Agorophius pygmaeus (Ashley Formation, lower Oligocene, South Carolina; 29.0-26.57 Ma) has been a critical point of comparison for studies of early neocete evolution owing to its early discovery as well as its transitional anatomy relative to archaeocete whales and modern odontocetes. Some time during the late nineteenth century the holotype skull went missing and has never been relocated; supplementary reference specimens have since been recently referred to the species from the Ashley Formation and the overlying Chandler Bridge Formation (upper Oligocene; 24.7-23.5). New crania referable to Agorophius sp. are identifiable to the genus based on several features of the intertemporal region. Furthermore, all published specimens from the Chandler Bridge Formation consistently share larger absolute size and a proportionally shorter exposure of the parietal in the skull roof than specimens from the Ashley Formation (including the holotype). Furthermore, these specimens include well-preserved ethmoid labyrinths and cribriform plates, indicating that Agorophius primitively retained a strong olfactory sense. These new crania suggest that at least two species of Agorophius are present in the Oligocene of South Carolina, revealing a somewhat more complicated taxonomic perspective. PMID- 30280009 TI - Using bioinformatics tools for the discovery of Dengue RNA-dependent RNA polymerase inhibitors. AB - Background: Dengue fever has rapidly manifested into a serious global health concern. The emergence of various viral serotypes has prompted the urgent need for innovative drug design techniques. Of the viral non-structural enzymes, the NS5 RNA-dependent RNA polymerase has been established as a promising target due to its lack of an enzymatic counterpart in mammalian cells and its conserved structure amongst all serotypes. The onus is now on scientists to probe further into understanding this enzyme and its mechanism of action. The field of bioinformatics has evolved greatly over recent decades, with updated drug design tools now being publically available. Methods: In this study, bioinformatics tools were used to provide a comprehensive sequence and structural analysis of the two most prominent serotypes of Dengue RNA-dependent RNA polymerase. A list of popular flavivirus inhibitors were also chosen to dock to the active site of the enzyme. The best docked compound was then used as a template to generate a pharmacophore model that may assist in the design of target-specific Dengue virus inhibitors. Results: Comparative sequence alignment exhibited similarity between all three domains of serotype 2 and 3.Sequence analysis revealed highly conserved regions at residues Meth530, Thr543 Asp597, Glu616, Arg659 and Pro671. Mapping of the active site demonstrated two highly conserved residues: Ser710 and Arg729. Of the active site interacting residues, Ser796 was common amongst all ten docked compounds, indicating its importance in the drug design process. Of the ten docked flavivirus inhibitors, NITD-203 showed the best binding affinity to the active site. Further pharmacophore modeling of NITD-203 depicted significant pharmacophoric elements that are necessary for stable binding to the active site. Discussion: This study utilized publically available bioinformatics tools to provide a comprehensive framework on Dengue RNA-dependent RNA polymerase. Based on docking studies, a pharmacophore model was also designed to unveil the crucial pharmacophoric elements that are required when constructing an efficacious DENV inhibitor. We believe that this study will be a cornerstone in paving the road toward the design of target-specific inhibitors against DENV RdRp. PMID- 30280013 TI - Assessing bird avoidance of high-contrast lights using a choice test approach: implications for reducing human-induced avian mortality. AB - Background: Avian collisions with man-made objects and vehicles (e.g., buildings, cars, airplanes, power lines) have increased recently. Lights have been proposed to alert birds and minimize the chances of collisions, but it is challenging to choose lights that are tuned to the avian eye and can also lead to avoidance given the differences between human and avian vision. We propose a choice test to address this problem by first identifying wavelengths of light that would over stimulate the retina using species-specific perceptual models and by then assessing the avoidance/attraction responses of brown-headed cowbirds to these lights during daytime using a behavioral assay. Methods: We used perceptual models to estimate wavelength-specific light emitting diode (LED) lights with high chromatic contrast. The behavioral assay consisted of an arena where the bird moved in a single direction and was forced to make a choice (right/left) using a single-choice design (one side with the light on, the other with the light off) under diurnal light conditions. Results: First, we identified lights with high saliency from the cowbird visual perspective: LED lights with peaks at 380 nm (ultraviolet), 470 nm (blue), 525 nm (green), 630 nm (red), and broad spectrum (white) LED lights. Second, we found that cowbirds significantly avoided LED lights with peaks at 470 and 630 nm, but did not avoid or prefer LED lights with peaks at 380 and 525 nm or white lights. Discussion: The two lights avoided had the highest chromatic contrast but relatively lower levels of achromatic contrast. Our approach can optimize limited resources to narrow down wavelengths of light with high visual saliency for a target species leading to avoidance. These lights can be used as candidates for visual deterrents to reduce collisions with man-made objects and vehicles. PMID- 30280015 TI - First record of Holothuria (Metriatyla) scabra Jaeger, 1833 (Echinodermata: Holothuroidea) from the coastal waters of the United Arab Emirates. AB - The presence of an endangered and economically valuable species of sea cucumber, Holothuria (Metriatyla) scabra Jaeger, 1833, was investigated in the Alqurm Wa Lehhfaiiah Protected Area near the city of Kalba in the Emirate of Sharjah. Sea cucumber specimens were collected, and identification was first conducted using morphological keys. H. scabra identification was confirmed through microscopic observation of ossicles. Though this species is known to occur in other regions along the Gulf of Oman, this paper represents the first published record of H. scabra, in the coastal waters of the United Arab Emirates. PMID- 30280014 TI - Leaf photosynthetic function duration during yield formation of large-spike wheat in rainfed cropping systems. AB - Improving photosynthetic capacity significantly affects the yield of wheat (Triticum aestivum L.) in rainfed regions. In this study, the physiological characteristics of eight large-spike wheat lines were compared with a multiple spike cultivar as a control (CK) in a field over two consecutive seasons: 2010 2012. The tillering peak was 7-21 d after returning green for line 2040, the average rate of decline of relative water content was slower, and the average duration time of photosynthetic rate was longer than CK in vitro. There was a strong linear and positive correlation between photosynthetic rate and root activity at jointing, flowering, and grain-filling stages. In addition, average yields were higher in large-spike lines than CK (multiple-spike cultivar). The results suggest that large-spike lines might have greater water retaining capacity during yield formation under rainfed conditions. PMID- 30280012 TI - Crystal structure and functional analysis of human C1ORF123. AB - Proteins of the DUF866 superfamily are exclusively found in eukaryotic cells. A member of the DUF866 superfamily, C1ORF123, is a human protein found in the open reading frame 123 of chromosome 1. The physiological role of C1ORF123 is yet to be determined. The only available protein structure of the DUF866 family shares just 26% sequence similarity and does not contain a zinc binding motif. Here, we present the crystal structure of the recombinant human C1ORF123 protein (rC1ORF123). The structure has a 2-fold internal symmetry dividing the monomeric protein into two mirrored halves that comprise of distinct electrostatic potential. The N-terminal half of rC1ORF123 includes a zinc-binding domain interacting with a zinc ion near to a potential ligand binding cavity. Functional studies of human C1ORF123 and its homologue in the fission yeast Schizosaccharomyces pombe (SpEss1) point to a role of DUF866 protein in mitochondrial oxidative phosphorylation. PMID- 30280016 TI - Morphometric traits in the fine-leaved fescues depend on ploidy level: the case of Festuca amethystina L. AB - Background: Polyploid specimens are usually characterized by greater exuberance: they reach larger sizes and/or have a larger number of some organs. Festuca amethystina L. belongs to the section Aulaxyper. Based on morphological features, four subspecies of F. amethystina have been already identified. On the other hand, it has two cytotypes: diploid and tetraploid. The main aim of our study was to distinguish morphological differences between the cytotypes of F. amethystina, assuming that its phenotype differs significantly. Methods: The nuclear DNA content was measured by flow cytometry in dry leaves from specimens originating from 13 populations of F. amethystina. Several macrometric and micrometric traits of stems, spikelets and leaf blades were taken into account in the comparative analysis of two cytotypes. Results: In the case of cytotypes, specimens of tetraploids were larger than diploids. The conducted morphometric analysis of leaf cross-sections showed significant differences between the cytotypes. Discussion: The research has confirmed for the first time that in the case of F. amethystina the principle of greater exuberance of polyploids is true. Differences between the cytotypes are statistically significant, however, they are not enough to make easy the distinction of cytotypes on the basis of the measurements themselves. Our findings favor the rule known in Festuca taxonomy as a whole, i.e. that the ploidy level can be one of the main classification criteria. PMID- 30280017 TI - Pre-imaginal conditioning alters adult sex pheromone response in Drosophila. AB - Pheromones are chemical signals that induce innate responses in individuals of the same species that may vary with physiological and developmental state. In Drosophila melanogaster, the most intensively studied pheromone is 11-cis vaccenyl acetate (cVA), which is synthezised in the male ejaculatory bulb and is transferred to the female during copulation. Among other effects, cVA inhibits male courtship of mated females. We found that male courtship inhibition depends on the amount of cVA and this effect is reduced in male flies derived from eggs covered with low to zero levels of cVA. This effect is not observed if the eggs are washed, or if the eggs are laid several days after copulation. This suggests that courtship suppression involves a form of pre-imaginal conditioning, which we show occurs during the early larval stage. The conditioning effect could not be rescued by synthetic cVA, indicating that it largely depends on conditioning by cVA and other maternally-transmitted factor(s). These experiments suggest that one of the primary behavioral effects of cVA is more plastic and less stereotypical than had hitherto been realised. PMID- 30280018 TI - Identification of an aquaculture poriferan "Pest with Potential" and its phylogenetic implications. AB - Correct identification and classification of sponges is challenging due to ambiguous or misleading morphological features. A particular case is a blue keratose sponge occasionally referred to as the "Blue Photo Sponge" among aquarists, which appears frequently (and in several cases unintended) in private aquaria. This spicule-less species, occasionally specified as Collospongia auris Bergquist, Cambie & Kernan 1990, not only displays a high phenotypic plasticity in growth form and colour, it also proliferates in aquacultures under standard conditions unlike most other sponges. Therefore, this species is regarded as a pest for most aquarists. In turn, the ease of cultivation and propagation in aquacultures qualifies this species as a model organism for a wide array of scientific applications. For these purposes, correct identification and classification are indispensable. We reconstructed ribosomal gene trees and determined this species as Lendenfeldia chondrodes (De Laubenfels, 1954) (Phyllospongiinae), distant to Collospongia auris, and corroborated by skeletal features. Additionally, the resulting phylogeny corroborated major shortcomings of the current Phyllospongiinae classification-its consequences are discussed. PMID- 30280020 TI - Different environmental gradients affect different measures of snake beta diversity in the Amazon rainforests. AB - Mechanisms generating and maintaining biodiversity at regional scales may be evaluated by quantifying beta-diversity along environmental gradients. Differences in assemblages result in biotic complementarities and redundancies among sites, which may be quantified through multi-dimensional approaches incorporating taxonomic beta-diversity (TBD), functional beta-diversity (FBD) and phylogenetic beta-diversity (PBD). Here we test the hypothesis that snake TBD, FBD and PBD are influenced by environmental gradients, independently of geographic distance. The gradients tested are expected to affect snake assemblages indirectly, such as clay content in the soil determining primary production and height above the nearest drainage determining prey availability, or directly, such as percentage of tree cover determining availability of resting and nesting sites, and climate (temperature and precipitation) causing physiological filtering. We sampled snakes in 21 sampling plots, each covering five km2, distributed over 880 km in the central-southern Amazon Basin. We used dissimilarities between sampling sites to quantify TBD, FBD and PBD, which were response variables in multiple-linear-regression and redundancy analysis models. We show that patterns of snake community composition based on TBD, FBD and PBD are associated with environmental heterogeneity in the Amazon. Despite positive correlations between all beta-diversity measures, TBD responded to different environmental gradients compared to FBD and PBD. Our findings suggest that multi dimensional approaches are more informative for ecological studies and conservation actions compared to a single diversity measure. PMID- 30280021 TI - Finding wolf homesites: improving the efficacy of howl surveys to study wolves. AB - Locating wolf (Canis lupus) homesites is valuable for understanding the foraging behavior, population dynamics, and reproductive ecology of wolves during summer. During this period wolf pack members (adults and pups) readily respond to simulated wolf howls (i.e., howl surveys), which allows researchers to estimate the location of the homesite via triangulation. Confirming the actual locations of homesites via ground truthing is labor intensive because of the error surrounding estimated locations. Our objectives were (1) to quantify observer error during howl surveys and compare amongst experience levels, (2) provide a simple method for locating homesites in the field by incorporating observer error, and (3) further document the value of this method for monitoring wolf packs throughout the summer. We located 17 homesites by howl surveys during 2015 2017 in the Greater Voyageurs Ecosystem, Minnesota, USA. Of 62 bearings taken by observers during howl surveys, bearings erred by an average of 7.6 degrees +/- 6.3 degrees (SD). There was no difference in observer error between novice and experienced observers. A simple way to increase efficiency when searching for homesites is to search concentric areas (bands) based on estimated observer error, specifically by: (1) adding +/-10 degrees error bands around howl survey bearings when >=3 bearings can be obtained, (2) +/-10 degrees and +/-20 degrees error bands when 2 bearings are obtained, and (3) +/-10 degrees and +/-26 degrees error bands when 1 bearing is obtained. By incorporating observer error and understanding how frequently and how far wolves move homesites, it is possible to monitor wolf packs and confirm most, if not all, homesites used by a pack from at least June until August without having a collared individual in a pack. PMID- 30280019 TI - E-cigarettes versus nicotine patches for perioperative smoking cessation: a pilot randomized trial. AB - Introduction: Cigarette smoking by surgical patients is associated with increased complications. E-cigarettes have emerged as a potential smoking cessation tool. We sought to determine the feasibility and acceptability of e-cigarettes, compared to nicotine patch, for perioperative smoking cessation in veterans. Methods: Preoperative patients were randomized to either the nicotine patch group (n = 10) or the e-cigarette group (n = 20). Both groups were given a free 6-week supply in a tapering dose. All patients received brief counseling, a brochure on perioperative smoking cessation, and referral to the California Smokers' Helpline. The primary outcome was rate of smoking cessation on day of surgery confirmed by exhaled carbon monoxide. Secondary outcomes included smoking habits, pulmonary function, adverse events, and satisfaction with the products on day of surgery and at 8-weeks follow-up. Results: Biochemically verified smoking cessation on day of surgery was similar in both groups. Change in forced expiratory volume in one second (FEV1) was 592 ml greater in the e-cigarette group (95% CI [153-1,031] ml, p = 0.01) and change in forced expiratory volume in one second to forced vital capacity ratio (FEV1/FVC ratio) was 40.1% greater in the e-cigarette group (95% CI [18.2%-78.4%], p = 0.04). Satisfaction with the product was similar in both groups. Discussion: E-cigarettes are a feasible tool for perioperative smoking cessation in veterans with quit rates comparable to nicotine replacement patch. Spirometry appears to be improved 8-weeks after initiating e-cigarettes compared to nicotine patch, possibly due to worse baseline spirometry and more smoking reduction in the e-cigarette group. An adequately powered study is recommended to determine if these results can be duplicated. PMID- 30280022 TI - Functional responses of a cosmopolitan invader demonstrate intraspecific variability in consumer-resource dynamics. AB - Background: Variability in the ecological impacts of invasive species across their geographical ranges may decrease the accuracy of risk assessments. Comparative functional response analysis can be used to estimate invasive consumer-resource dynamics, explain impact variability, and thus potentially inform impact predictions. The European green crab (Carcinus maenas) has been introduced on multiple continents beyond its native range, although its ecological impacts appear to vary among populations and regions. Our aim was to test whether consumer-resource dynamics under standardized conditions are similarly variable across the current geographic distribution of green crab, and to identify correlated morphological features. Methods: Crabs were collected from multiple populations within both native (Northern Ireland) and invasive regions (South Africa and Canada). Their functional responses to local mussels (Mytilus spp.) were tested. Attack rates and handling times were compared among green crab populations within each region, and among regions (Pacific Canada, Atlantic Canada, South Africa, and Northern Ireland). The effect of predator and prey morphology on prey consumption was investigated. Results: Across regions, green crabs consumed prey according to a Type II (hyperbolic) functional response curve. Attack rates (i.e., the rate at which a predator finds and attacks prey), handling times and maximum feeding rates differed among regions. There was a trend toward higher attack rates in invasive than in native populations. Green crabs from Canada had lower handling times and thus higher maximum feeding rates than those from South Africa and Northern Ireland. Canadian and Northern Ireland crabs had significantly larger claws than South African crabs. Claw size was a more important predictor of the proportion of mussels killed than prey shell strength. Discussion: The differences in functional response between regions reflect observed impacts of green crabs in the wild. This suggests that an understanding of consumer-resource dynamics (e.g., the per capita measure of predation), derived from simple, standardized experiments, might yield useful predictions of invader impacts across geographical ranges. PMID- 30280023 TI - Successful transplantation of guinea pig gut microbiota in mice and its effect on pneumonic plague sensitivity. AB - Microbiota-driven variations in the inflammatory response are predicted to regulate host responses to infection. Increasing evidence indicates that the gastrointestinal and respiratory tracts have an intimate relationship with each other. Gut microbiota can influence lung immunity whereby gut-derived injurious factors can reach the lungs and systemic circulation via the intestinal lymphatics. The intestinal microbiota's ability to resist colonization can be extended to systemic infections or to pathogens infecting distant sites such as the lungs. Unlike the situation with large mammals, the microtus Yersinia pestis 201 strain exhibits strong virulence in mice, but nearly no virulence to large mammals (such as guinea pigs). Hence, to assess whether the intestinal microbiota from guinea pigs was able to affect the sensitivity of mice to challenge infection with the Y. pestis 201 strain, we fed mice with guinea pig diets for two months, after which they were administered 0.5 ml of guinea pig fecal suspension for 30 days by oral gavage. The stools from each mouse were collected on days 0, 15, and 30, DNA was extracted from them, and 16S rRNA sequencing was performed to assess the diversity and composition of the gut microbiota. We found that the intestinal microbiota transplants from the guinea pigs were able to colonize the mouse intestines. The mice were then infected with Yersinia pestis 201 by lung invasion, but no statistical difference was found in the survival rates of the mice that were colonized with the guinea pig's gut microbiota and the control mice. This indicates that the intestinal microbiota transplantation from the guinea pigs did not affect the sensitivity of the mice to pneumonic plague. PMID- 30280024 TI - Analysis of relative abundances with zeros on environmental gradients: a multinomial regression model. AB - Ecologists often analyze relative abundances, which are an example of compositional data. However, they have made surprisingly little use of recent advances in the field of compositional data analysis. Compositions form a vector space in which addition and scalar multiplication are replaced by operations known as perturbation and powering. This algebraic structure makes it easy to understand how relative abundances change along environmental gradients. We illustrate this with an analysis of changes in hard-substrate marine communities along a depth gradient. We fit a quadratic multivariate regression model with multinomial observations to point count data obtained from video transects. As well as being an appropriate observation model in this case, the multinomial deals with the problem of zeros, which often makes compositional data analysis difficult. We show how the algebra of compositions can be used to understand patterns in dissimilarity. We use the calculus of simplex-valued functions to estimate rates of change, and to summarize the structure of the community over a vertical slice. We discuss the benefits of the compositional approach in the interpretation and visualization of relative abundance data. PMID- 30280025 TI - Dynamics of nitrogen and active nitrogen components across seasons under varying stand densities in a Larix principis-rupprechtii (Pinaceae) plantation. AB - Changes in the concentration of soil nitrogen (N) or its components may directly affect ecosystem functioning in forestry. Thinning of forest stands, a widely used forestry management practice, may transform soil nutrients directly by altering the soil environment, or indirectly by changing above- or belowground plant biomass. The study objectives were to determine how tree stem density affects the soil N pool and what mechanisms drive any potential changes. In this study, N and its active components were measured in the soil of a Larix principis rupprechtii plantation across two full growing seasons, in 12 (25 * 25 m) plots: (low thinning, removal of 15% of the trees, three plot repetitions), moderate thinning (MT) (35% removal) and heavy thinning (HT) (50% removal) and no thinning control. Environmental indices, like the light condition, soil respiration, soil temperatures, and prescription, were measured in the plots also. Results indicated that soil total nitrogen (STN) was affected by tree stem density adjustments in the short-term; STN generally increased with decreasing tree stem density, reaching its highest concentration in the MT treatment before decreasing in HT. This pattern was echoed by the DON/STN ratio dissolved organic nitrogen (DON) under MT. A lower DON/STN was measured across the seasons. Microbial biomass nitrogen (MBN) and the SOC/STN (soil organic carbon (SOC)) ratio and density treatments influenced MBN concentration and inhibited SOC/STN. MT tended to accumulate more STN, produce lower DON/STN and had a generally higher microbial activity, which may be partly ascribed to the higher MBN value, MBN/STN ratio and lower DON/STN. The water conditions (soil moisture), light and soil temperatures could partly be responsible for the N pool dynamic in the different density treatments. PMID- 30280026 TI - Variation of soil bacterial communities along a chronosequence of Eucalyptus plantation. AB - Eucalyptus is harvested for wood and fiber production in many tropical and sub tropical habitats globally. Plantation has been controversial because of its influence on the surrounding environment, however, the influence of massive Eucalyptus planting on soil microbial communities is unclear. Here we applied high-throughput sequencing of the 16S rRNA gene to assess the microbial community composition and diversity of planting chronosequences, involving two, five and ten years of Eucalyptus plantation, comparing to that of secondary-forest in South China. We found that significant changes in the composition of soil bacteria occurred when the forests were converted from secondary-forest to Eucalyptus. The bacterial community structure was clearly distinct from control and five year samples after Eucalyptus was grown for 2 and 10 years, highlighting the influence of this plantation on local soil microbial communities. These groupings indicated a cycle of impact (2 and 10 year plantations) and low impact (5-year plantations) in this chronosequence of Eucalyptus plantation. Community patterns were underpinned by shifts in soil properties such as pH and phosphorus concentration. Concurrently, key soil taxonomic groups such as Actinobacteria showed abundance shifts, increasing in impacted plantations and decreasing in low impacted samples. Shifts in taxonomy were reflected in a shift in metabolic potential, including pathways for nutrient cycles such as carbon fixation, which changed in abundance over time following Eucalyptus plantation. Combined these results confirm that Eucalyptus plantation can change the community structure and diversity of soil microorganisms with strong implications for land-management and maintaining the health of these ecosystems. PMID- 30280028 TI - Xeno-miRNet: a comprehensive database and analytics platform to explore xeno miRNAs and their potential targets. AB - Xeno-miRNAs are microRNAs originating from exogenous species detected in host biofluids. A growing number of studies have suggested that many of these xeno miRNAs may be involved in cross-species interactions and manipulations. To date, hundreds of xeno-miRNAs have been reported in different hosts at various abundance levels. Based on computational predictions, many more miRNAs could be potentially transferred to human circulation system. There is a clear need for bioinformatics resources and tools dedicated to xeno-miRNA annotations and their potential functions. To address this need, we have systematically curated xeno miRNAs from multiple sources, performed target predictions using well-established algorithms, and developed a user-friendly web-based tool-Xeno-miRNet-to allow researchers to search and explore xeno-miRNAs and their potential targets within different host species. Xeno-miRNet currently contains 1,702 (including both detected and predicted) xeno-miRNAs from 54 species and 98,053 potential gene targets in six hosts. The web application is freely available at http://xeno.mirnet.ca. PMID- 30280029 TI - Closing the gap: mixed stock analysis of three foraging populations of green turtles (Chelonia mydas) on the Great Barrier Reef. AB - A solid understanding of the spatial ecology of green turtles (Chelonia mydas) is fundamental to their effective conservation. Yet this species, like many marine migratory species, is challenging to monitor and manage because they utilise a variety of habitats that span wide spatio-temporal scales. To further elucidate the connectivity between green turtle rookeries and foraging populations, we sequenced the mtDNA control region of 278 turtles across three foraging sites from the northern Great Barrier Reef (GBR) spanning more than 330 km: Cockle Bay, Green Island and Low Isles. This was performed with a newly developed assay, which targets a longer fragment of mtDNA than previous studies. We used a mixed stock analysis (MSA), which utilises genetic data to estimate the relative proportion of genetically distinct breeding populations found at a given foraging ground. Haplotype and nucleotide diversity was also assessed. A total of 35 haplotypes were identified across all sites, 13 of which had not been found previously in any rookery. The MSA showed that the northern GBR (nGBR), Coral Sea (CS), southern GBR (sGBR) and New Caledonia (NC) stocks supplied the bulk of the turtles at all three sites, with small contributions from other rookeries in the region. Stock contribution shifted gradually from north to south, although sGBR/CS stock dominated at all three sites. The major change in composition occured between Cockle Bay and Low Isles. Our findings, together with other recent studies in this field, show that stock composition shifts with latitude as a natural progression along a coastal gradient. This phenomenon is likely to be the result of ocean currents influencing both post-hatchling dispersal and subsequent juvenile recruitment to diverse coastal foraging sites. PMID- 30280030 TI - New mud dragons from Svalbard: three new species of Cristaphyes and the first Arctic species of Pycnophyes (Kinorhyncha: Allomalorhagida: Pycnophyidae). AB - Background: Kinorhynchs are marine, microscopic invertebrates inhabiting the seafloors. Their segmented trunk equipped with spines and processes has inspired scientists to give them the common name "mud dragons." Even though kinorhynchs have been known since the 19th century, less than 300 species are known to science, and it is still considered a largely understudied animal group-in particular in the Arctic, from which only 23 species are known so far. Methods: Samples were collected at eight stations around Svalbard and in the fjords of Spitsbergen. Meiofauna was extracted from the sediment cores with LUDOX centrifugation method, and kinorhynchs were picked up and mounted for light- and scanning electron microscopy. Results: Four new species of the kinorhynch family Pycnophyidae are described from Svalbard: Cristaphyes dordaidelosensis sp. nov., C. glaurung sp. nov., C. scatha sp. nov., and Pycnophyes ancalagon sp. nov. The new species are generally recognized by their distribution of setae along the trunk segments. Discussion: After the discovery of the new species, Pycnophyidae becomes with 14 species the most diverse kinorhynch genus in the Arctic, closely followed by Echinoderidae with 13 species. So far, these are the only kinorhynch families with an Arctic distribution. PMID- 30280027 TI - Molecular analysis of oral microflora in patients with primary Sjogren's syndrome by using high-throughput sequencing. AB - Background: The objective of this study was to characterize the oral microflora profile of primary Sjogren's syndrome (pSS) patients, thereby revealing the connection between oral bacterial composition and dental caries, and to identify the "core microbiome" in the oral cavities of pSS patients and systemic healthy individuals by using a high-throughput sequencing technique. Methods: Twenty-two pSS patients and 23 healthy controls were enrolled in this study. Their clinical data and oral rinse samples were collected. The V3-V4 hypervariable regions of the bacterial 16S rRNA gene of samples were amplified and analyzed by high throughput sequencing on the Illumina Miseq PE300 platform. Results: Both two groups were age- and sex-matched. There were significantly higher decayed, missing and filled teeth (DMFT) and decayed, missing and filled surfaces (DMFS) in the pSS group than in the control group (p < 0.01). Alpha diversity was depleted in pSS patients, compared with healthy controls (p < 0.01), while beta diversity between the two groups was not significantly different. Seven discriminative genera (LDA > 4) were found between the two groups in LEfSe (LDA Effect Size) analysis. The relative abundance of Veillonella in pSS patients was fourfold higher, while Actinomyces, Haemophilus, Neisseria, Rothia, Porphyromonas and Peptostreptococcus were significantly lower in pSS patients than in healthy controls. However, the correlation between Veillonella and DMFT/DMFS was not significant (p > 0.05). In Venn diagram analysis, nine genera shared by all samples of two groups, which comprised 71.88% and 67.64% in pSS patients and controls, respectively. Discussion: These findings indicate a microbial dysbiosis in pSS patients; notably, Veillonella might be recognized as a biomarker in pSS patients. The core microbiome in pSS patients was similar to the systemic healthy population. These provide insight regarding advanced microbial prevention and treatment of severe dental caries in pSS patients. This study also provides basic data regarding microbiology in pSS. PMID- 30280032 TI - Human dimensions of wildfires in NW Spain: causes, value of the burned vegetation and administrative measures. AB - Exploring the human dimensions of forest fires is a crucial, although often overlooked, aspect of wildfire research, since wildfires often have important socio-economic impacts and humans are nowadays the main cause of wildfires in many areas of the world. We carried out a telephone survey (N = 345 interviews) in one of the most fire-prone areas in Europe (NW Spain) in order to assess citizens' awareness about wildfire causes and risks, their perception of the value of the vegetation and of administrative measures to fight against fires. Perceptions of respondents about fire causes were in general realistic although fires caused by pyromaniacs and for profit were overestimated, while vegetation management was comparatively underestimated. Citizens were broadly aware of the fire risk associated with different vegetation types, rightly considering native oak forests and agricultural fields as less risky than shrublands and pine and eucalypt plantations. Tree-dominated vegetation was more valued than treeless formations, and native forests more than tree plantations, which seems related to a preference for ecological value over utilitarian considerations. In addition, the value of eucalypt plantations was clearly affected by the education level of respondents, being less valued as the education level increased. Most citizens considered that the administration was not doing enough to fight against fires. The law that compels landowners to reduce fuels in wildland-urban interfaces was considered effective by most respondents (72%), but 50% considered it difficult to implement by landowners. This may explain the poor degree of compliance of this law. PMID- 30280031 TI - Assessing the role of dispersed floral resources for managed bees in providing supporting ecosystem services for crop pollination. AB - Most pollination ecosystem services studies have focussed on wild pollinators and their dependence on natural floral resources adjacent to crop fields. However, managed pollinators depend on a mixture of floral resources that are spatially separated from the crop field. Here, we consider the supporting role these resources play as an ecosystem services provider to quantify the use and availability of floral resources, and to estimate their relative contribution to support pollination services of managed honeybees. Beekeepers supplying pollination services to the Western Cape deciduous fruit industry were interviewed to obtain information on their use of floral resources. For 120 apiary sites, we also analysed floral resources within a two km radius of each site based on geographic data. The relative availability of floral resources at sites was compared to regional availability. The relative contribution of floral resources-types to sustain managed honeybees was estimated. Beekeepers showed a strong preference for eucalypts and canola. Beekeepers selectively placed more hives at sites with eucalypt and canola and less with natural vegetation. However, at the landscape-scale, eucalypt was the least available resource, whereas natural vegetation was most common. Based on analysis of apiary sites, we estimated that 700,818 ha of natural vegetation, 73,910 ha of canola fields, and 10,485 ha of eucalypt are used to support the managed honeybee industry in the Western Cape. Whereas the Cape managed honeybee system uses a bee native to the region, alien plant species appear disproportionately important among the floral resources being exploited. We suggest that an integrated approach, including evidence from interview and landscape data, and fine-scale biological data is needed to study floral resources supporting managed honeybees. PMID- 30280034 TI - Effect of changes in the fractal structure of a littoral zone in the course of lake succession on the abundance, body size sequence and biomass of beetles. AB - Dystrophic lakes undergo natural disharmonic succession, in the course of which an increasingly complex and diverse, mosaic-like pattern of habitats evolves. In the final seral stage, the most important role is played by a spreading Sphagnum mat, which gradually reduces the lake's open water surface area. Long-term transformations in the primary structure of lakes cause changes in the structure of lake-dwelling fauna assemblages. Knowledge of the succession mechanisms in lake fauna is essential for proper lake management. The use of fractal concepts helps to explain the character of fauna in relation to other aspects of the changing complexity of habitats. Our 12-year-long study into the succession of water beetles has covered habitats of 40 selected lakes which are diverse in terms of the fractal dimension. The taxonomic diversity and density of lake beetles increase parallel to an increase in the fractal dimension. An in-depth analysis of the fractal structure proved to be helpful in explaining the directional changes in fauna induced by the natural succession of lakes. Negative correlations appear between the body size and abundance. An increase in the density of beetles within the higher dimension fractals is counterbalanced by a change in the size of individual organisms. As a result, the biomass is constant, regardless of the fractal dimension. PMID- 30280033 TI - High-throughput metabarcoding reveals the effect of physicochemical soil properties on soil and litter biodiversity and community turnover across Amazonia. AB - Background: Knowledge on the globally outstanding Amazonian biodiversity and its environmental determinants stems almost exclusively from aboveground organisms, notably plants. In contrast, the environmental factors and habitat preferences that drive diversity patterns for micro-organisms in the ground remain elusive, despite the fact that micro-organisms constitute the overwhelming majority of life forms in any given location, in terms of both diversity and abundance. Here we address how the diversity and community turnover of operational taxonomic units (OTU) of organisms in soil and litter respond to soil physicochemical properties; whether OTU diversities and community composition in soil and litter are correlated with each other; and whether they respond in a similar way to soil properties. Methods: We used recently inferred OTUs from high-throughput metabarcoding of the 16S (prokaryotes) and 18S (eukaryotes) genes to estimate OTU diversity (OTU richness and effective number of OTUs) and community composition for prokaryotes and eukaryotes in soil and litter across four localities in Brazilian Amazonia. All analyses were run separately for prokaryote and eukaryote OTUs, and for each group using both presence-absence and abundance data. Combining these with novel data on soil chemical and physical properties, we identify abiotic correlates of soil and litter organism diversity and community structure using regression, ordination, and variance partitioning analysis. Results: Soil organic carbon content was the strongest factor explaining OTU diversity (negative correlation) and pH was the strongest factor explaining community turnover for prokaryotes and eukaryotes in both soil and litter. We found significant effects also for other soil variables, including both chemical and physical properties. The correlation between OTU diversity in litter and in soil was non-significant for eukaryotes and weak for prokaryotes. The community compositions of both prokaryotes and eukaryotes were more separated among habitat types (terra-firme, varzea, igapo and campina) than between substrates (soil and litter). Discussion: In spite of the limited sampling (four localities, 39 plots), our results provide a broad-scale view of the physical and chemical correlations of soil and litter biodiversity in a longitudinal transect across the world's largest rainforest. Our methods help to understand links between soil properties, OTU diversity patterns, and community composition and turnover. The lack of strong correlation between OTU diversity in litter and in soil suggests independence of diversity drives of these substrates and highlights the importance of including both measures in biodiversity assessments. Massive sequencing of soil and litter samples holds the potential to complement traditional biological inventories in advancing our understanding of the factors affecting tropical diversity. PMID- 30280035 TI - Wind-driven spume droplet production and the transport of Pseudomonas syringae from aquatic environments. AB - Natural aquatic environments such as oceans, lakes, and rivers are home to a tremendous diversity of microorganisms. Some may cross the air-water interface within droplets and become airborne, with the potential to impact the Earth's radiation budget, precipitation processes, and spread of disease. Larger droplets are likely to return to the water or adjacent land, but smaller droplets may be suspended in the atmosphere for transport over long distances. Here, we report on a series of controlled laboratory experiments to quantify wind-driven droplet production from a freshwater source for low wind speeds. The rate of droplet production increased quadratically with wind speed above a critical value (10-m equivalent 5.7 m/s) where droplet production initiated. Droplet diameter and ejection speeds were fit by a gamma distribution. The droplet mass flux and momentum flux increased with wind speed. Two mechanisms of droplet production, bubble bursting and fragmentation, yielded different distributions for diameter, speed, and angle. At a wind speed of about 3.5 m/s, aqueous suspensions of the ice-nucleating bacterium Pseudomonas syringae were collected at rates of 283 cells m-2 s-1 at 5 cm above the water surface, and at 14 cells m-2 s-1 at 10 cm above the water surface. At a wind speed of about 4.0 m/s, aqueous suspensions of P. syringae were collected at rates of 509 cells m-2 s-1 at 5 cm above the water surface, and at 81 cells m-2 s-1 at 10 cm above the water surface. The potential for microbial flux into the atmosphere from aquatic environments was calculated using known concentrations of bacteria in natural freshwater systems. Up to 3.1 * 104 cells m-2 s-1 of water surface were estimated to leave the water in potentially suspended droplets (diameters <100 um). Understanding the sources and mechanisms for bacteria to aerosolize from freshwater aquatic sources may aid in designing management strategies for pathogenic bacteria, and could shed light on how bacteria are involved in mesoscale atmospheric processes. PMID- 30280036 TI - Plurality in multi-disciplinary research: multiple institutional affiliations are associated with increased citations. AB - Background: The institutional affiliations and associated collaborative networks that scientists foster during their research careers are salient in the production of high-quality science. The phenomenon of multiple institutional affiliations and its relationship to research output remains relatively unexplored in the literature. Methods: We examined 27,612 scientific articles, modelling the normalized citation counts received against the number of authors and affiliations held. Results: In agreement with previous research, we found that teamwork is an important factor in high impact papers, with average citations received increasing concordant with the number of co-authors listed. For articles with more than five co-authors, we noted an increase in average citations received when authors with more than one institutional affiliation contributed to the research. Discussion: Multiple author affiliations may play a positive role in the production of high-impact science. This increased researcher mobility should be viewed by institutional boards as meritorious in the pursuit of scientific discovery. PMID- 30280037 TI - Tumor-preventing activity of aspirin in multiple cancers based on bioinformatic analyses. AB - Background: Acetylsalicylic acid was renamed aspirin in 1899, and it has been widely used for its multiple biological actions. Because of the diversity of the cellular processes and diseases that aspirin reportedly affects and benefits, uncertainty remains regarding its mechanism in different biological systems. Methods: The Drugbank and STITCH databases were used to find direct protein targets (DPTs) of aspirin. The Mentha database was used to analyze protein protein interactions (PPIs) to find DPT-associated genes. DAVID was used for the GO and KEGG enrichment analyses. The cBio Cancer Genomics Portal database was used to mine genetic alterations and networks of aspirin-associated genes in cancer. Results: Eighteen direct protein targets (DPT) and 961 DPT-associated genes were identified for aspirin. This enrichment analysis resulted in eight identified KEGG pathways that were associated with cancers. Analysis using the cBio portal indicated that aspirin might have effects on multiple tumor suppressors, such as TP53, PTEN, and RB1 and that TP53 might play a central role in aspirin-associated genes. Discussion: The results not only suggest that aspirin might have anti-tumor actions against multiple cancers but could also provide new directions for further research on aspirin using a bioinformatics analysis approach. PMID- 30280038 TI - Distribution, habitat associations, and conservation status updates for the pilose crayfish Pacifastacus gambelii (Girard, 1852) and Snake River pilose crayfish Pacifastacus connectens (Faxon, 1914) of the western United States. AB - Our study evaluates the distribution, habitat associations, and current conservation status of the Snake River pilose crayfish Pacifastacus connectens (Faxon, 1914) and pilose crayfish Pacifastacus gambelii (Girard, 1852), two little-studied and data-deficient species endemic to the western United States. We first developed a species distribution model (SDM) for the pilose crayfishes based on their historical occurrence records using boosted regression trees and freshwater GIS data layers. We then sampled 163 sites in the summers of 2016 and 2017 within the distribution of these crayfishes, including 50 where these species were observed historically. We next compared our field results to modeled predictions of suitable habitat from the SDM. Our SDM predicted 73 sites (45%) we sampled as suitable for the pilose crayfishes, with a moderate AUC value of 0.824. The pilose crayfishes were generally predicted to occur in larger streams and rivers with less extreme upstream temperature and precipitation seasonality. We found the pilose crayfishes at only 20 (12%) of the 163 total sites we sampled, 14 (20%) of the 73 sites predicted as suitable for them by our SDM, and 12 (24%) of 50 historical sites that we sampled. We found the invasive virile crayfish Faxonius virilis (Hagen, 1870) at 22 sites total and 12 (24%) historical sites for the pilose crayfishes, and we found the "native invader" signal crayfish Pacifastacus leniusculus (Dana, 1852) at 29 sites total and 6 (12%) historical sites for the pilose crayfishes. We subsequently used a single classification tree to identify factors associated with our high rate of false positives for contemporary pilose crayfish distributions relative to our SDM. This classification tree identified the presence of invasive crayfishes, impairment of the benthic community, and sampling method as some of the factors differentiating false positives relative to true positives for the pilose crayfishes. Our study identified the historical distribution and habitat associations for P. connectens and P. gambelii using an SDM and contrasted this prediction to results of contemporary field sampling. We found that the pilose crayfishes have seemingly experienced substantial range declines, attributable to apparent displacement by invasive crayfishes and impairment or change to stream communities and habitat. We recommend increased conservation and management attention to P. connectens and P. gambelii in response to these findings. PMID- 30280039 TI - Growth and feeding of deep-sea coral Lophelia pertusa from the California margin under simulated ocean acidification conditions. AB - The global decrease in seawater pH known as ocean acidification has important ecological consequences and is an imminent threat for numerous marine organisms. Even though the deep sea is generally considered to be a stable environment, it can be dynamic and vulnerable to anthropogenic disturbances including increasing temperature, deoxygenation, ocean acidification and pollution. Lophelia pertusa is among the better-studied cold-water corals but was only recently documented along the US West Coast, growing in acidified conditions. In the present study, coral fragments were collected at ~300 m depth along the southern California margin and kept in recirculating tanks simulating conditions normally found in the natural environment for this species. At the collection site, waters exhibited persistently low pH and aragonite saturation states (Omegaarag) with average values for pH of 7.66 +/- 0.01 and Omegaarag of 0.81 +/- 0.07. In the laboratory, fragments were grown for three weeks in "favorable" pH/Omegaarag of 7.9/1.47 (aragonite saturated) and "unfavorable" pH/Omegaarag of 7.6/0.84 (aragonite undersaturated) conditions. There was a highly significant treatment effect (P < 0.001) with an average% net calcification for favorable conditions of 0.023 +/- 0.009% d-1 and net dissolution of -0.010 +/- 0.014% d-1 for unfavorable conditions. We did not find any treatment effect on feeding rates, which suggests that corals did not depress feeding in low pH/ Omegaarag in an attempt to conserve energy. However, these results suggest that the suboptimal conditions for L. pertusa from the California margin could potentially threaten the persistence of this cold-water coral with negative consequences for the future stability of this already fragile ecosystem. PMID- 30280040 TI - Biosorption potential of natural, pyrolysed and acid-assisted pyrolysed sugarcane bagasse for the removal of lead from contaminated water. AB - Lead (Pb) is a ubiquitous pollutant which poses serious threats to plants, animals and humans once entered into the food chain via contaminated industrial effluents on their discharge into the surface of water bodies and/or geological materials. This study aimed to examine and compare the biosorption potential of natural sugarcane bagasse (NB), pyrolysed sugarcane bagasse (PB) and acid assisted pyrolysed sugarcane bagasse (APB) for the removal of Pb from contaminated water. To explore this objective, a series of batch experiments were conducted at various adsorbent mass (0.25, 0.5, 0.75, 1.0 g per 100 ml contaminated water), initial Pb concentration (7, 15, 30, 60 and 120 ppm), and contact time (7, 15, 30, 60 and 120 min). Results revealed that all the tested bio-sorbents have potential to adsorb and remove Pb ions from the contaminated water. In this regard, APB proved more effective since it removed 98% of Pb from aqueous solution at initial Pb concentration of 7 ppm and mass of 0.25 g per 100 ml of aqueous solution. The respective values in case of NB and PB were 90 and 95%. For a given adsorbent type, Pb adsorption decreased by increasing the mass from 0.25 to 1.0 g per 100 ml of aqueous solution. However, the greatest Pb removal occurred at adsorbent mass of 1.0 g per 100 ml of aqueous solution. Initial Pb concentration had a great impact on Pb adsorption and removal by adsorbent. The former increased and the latter decreased with the increase in initial Pb concentration from seven to 120 ppm. At seven ppm Pb concentration, maximum Pb removal took place irrespective to the adsorbent type. Out of the total Pb adsorption and removal, maximum contribution occurred within 15 min of contact time between the adsorbate and adsorbent, which slightly increased till 30 min, thereafter, it reached to equilibrium. Application of equilibrium isotherm models revealed that our results were better fitted with Freundlich adsorption isotherm model. Overall, and for the reasons detailed above, it is concluded that sugarcane bagasse has capabilities to adsorb and remove Pb ions from contaminated water. Its bio-sorption potential was considerably increased after pyrolysis and acid treatment. PMID- 30280041 TI - Population history of deep-sea vent and seep Provanna snails (Mollusca: Abyssochrysoidea) in the northwestern Pacific. AB - Background: Gastropods of the genus Provanna are abundant and widely distributed in deep-sea chemosynthetic environments with seven extant species described in the northwestern Pacific. Methods: We investigated the population history and connectivity of five Provanna species in the northwestern Pacific through population genetic analyses using partial sequences of the cytochrome c oxidase subunit I gene. Results: We found that P. subglabra, the most abundant and genetically diverse species, is genetically segregated by depth. Among the five species, the three comparatively shallower species (P. lucida, P. kuroshimensis, P. glabra) had a more constant demographic history compared to the deeper species (P. subglabra, P. clathrata). Discussion: Environmental differences, especially depth, appears to have a role in the segregation of Provanna snails. The population of P. clathrata in the Irabu Knoll appears to have expanded after P. subglabra population. The remaining three species, P. lucida, P. kuroshimensis, and P. glabra, are only known from a single site each, all of which were shallower than 1,000 m. These data indicate that Provanna gastropods are vertically segregated, and that their population characteristics likely depend on hydrothermal activities. PMID- 30280042 TI - Size dimorphism and sexual segregation in pheasants: tests of three competing hypotheses. AB - Fine scale sexual segregation outside of the mating season is common in sexually dimorphic and polygamous species, particularly in ungulates. A number of hypotheses predict sexual segregation but these are often contradictory with no agreement as to a common cause, perhaps because they are species specific. We explicitly tested three of these hypotheses which are commonly linked by a dependence on sexual dimorphism for animals which exhibit fine-scale sexual segregation; the Predation Risk Hypothesis, the Forage Selection Hypothesis, and the Activity Budget Hypothesis, in a single system the pheasant, Phasianus colchicus; a large, sedentary bird that is predominantly terrestrial and therefore analogous to ungulates rather than many avian species which sexually segregate. Over four years we reared 2,400 individually tagged pheasants from one day old and after a period of 8-10 weeks we released them into the wild. We then followed the birds for 7 months, during the period that they sexually segregate, determined their fate and collected behavioural and morphological measures pertinent to the hypotheses. Pheasants are sexually dimorphic during the entire period that they sexually segregate in the wild; males are larger than females in both body size and gut measurements. However, this did not influence predation risk and predation rates (as predicted by the Predation Risk Hypothesis), diet choice (as predicted by the Forage Selection Hypothesis), or the amount of time spent foraging, resting or walking (as predicted by the Activity Budget Hypothesis). We conclude that adult sexual size dimorphism is not responsible for sexual segregation in the pheasant in the wild. Instead, we consider that segregation may be mediated by other, perhaps social, factors. We highlight the importance of studies on a wide range of taxa to help further the knowledge of sexual segregation. PMID- 30280043 TI - Distinguishing between enduring and dynamic concussion symptoms: applying Generalisability Theory to the Rivermead Post Concussion Symptoms Questionnaire (RPQ). AB - Background: The Rivermead Post Concussion Symptoms Questionnaire (RPQ) is a widely-used, 16-item measure of concussion symptoms yet its ability to assess change in the symptom experience over time has come under criticism. We applied Generalisability theory to differentiate between dynamic and enduring aspects of post-concussion symptoms and to examine sources of measurement error in the RPQ. Materials and Methods: Generalisability theory was applied using the longitudinal design with persons as the object of measurement. Patients with a traumatic brain injury (n = 145; aged >=16 years) were assessed at three time occasions (1, 6 and 12 months post-injury) using the RPQ. Results: The RPQ showed overall strong generalisability of scores (G = .98) across persons and occasions with a minor proportion of variance attributed to the dynamic aspect of symptoms reflected by interaction between person and occasion. Items measuring concentration, fatigue, restlessness and irritability reflected more dynamic patterns compared to more enduring patterns of sensitivity to noise, impatience, nausea and sleep disturbance. Conclusion: The RPQ demonstrated strong reliability in assessing enduring post-concussion symptoms but its ability to assess dynamic symptoms is limited. Clinicians should exercise caution in use of the RPQ to track dynamic symptom change over time. Further investigation is necessary to enhance the RPQ's ability to assess dynamic symptoms and to address measurement error associated with individual items. PMID- 30280044 TI - In silico study of medical decision-making for rare diseases: heterogeneity of decision-makers in a population improves overall benefit. AB - Background: Medical decision-making is difficult when information is limited due to its rareness. For example, there are two treatment options for patients affected by a rare disease with high lethality. The information about both treatment effects is unavailable or very limited. Patients are inclined to accept one of the interventions rather than waiting for death, but they are reluctant to be assigned the inferior one. While a single patient selects one treatment that seems better based on the limited information, he or she loses the chance to select the other treatment, which may be the better option. This is the so-called dilemma between exploitation (enjoying the benefits of using current knowledge) and exploration (taking the risk to obtain new knowledge). In clinical settings, the statistical advice for individual patients seems to be the maximum expected success rate or something equivalent and patients' selections tend to be homogeneous, which does not solve the dilemma. In this study, our aim is to investigate the effects of the heterogeneity of decision-makers in the decision process. Methods: Here, we proposed a decision strategy that introduced the heterogeneity of decision-makers by considering patients' self-decisions where the patients' heterogeneous attitudes towards the treatment are integrated into the probabilistic utility function based on the Beta Bayesian posterior. Based on the context of two-armed bandit treatment options with limited information, we compared the overall success rate of treatment between our heterogeneous decision strategy and a homogeneous decision strategy that is defined to select the treatment with the largest posterior mean. Results: The heterogeneity of decision makers in a population improved the overall benefit of treatment under some conditions. Discussion: In clinical settings, there exists heterogeneity of decision-making among patients. Our study investigated a targeting strategy by respecting the self-decision of all individuals and found that the heterogeneity of decision-making can improve the overall benefit under some conditions. In addition, this outperformance may suggest that heterogeneity of decision-making is of importance to human beings. Besides the ethical merit, our findings provide meaningful ideas for better strategies towards decision-making dilemmas in clinical settings for rare diseases or cases where only limited information is available. Furthermore, it is suggested to investigate the effects of heterogeneity of decision-making in other fashions, such as genetic heterogeneity and phenotypic heterogeneity. PMID- 30280045 TI - Cellular production of a counterfeit viral protein confers immunity to infection by a related virus. AB - DNA copies of many non-retroviral RNA virus genes or portions thereof (NIRVs) are present in the nuclear genomes of many eukaryotes. These have often been preserved for millions of years of evolution, suggesting that they play an important cellular function. One possible function is resistance to infection by related viruses. In some cases, this appears to occur through the piRNA system, but in others by way of counterfeit viral proteins encoded by NIRVs. In the fungi, NIRVs may be as long as 1,400 uninterrupted codons. In one such case in the yeast Debaryomyces hansenii, one of these genes provides immunity to a related virus by virtue of expression of a counterfeit viral capsid protein, which interferes with assembly of viral capsids by negative complementation. The widespread occurrence of non-retroviral RNA virus genes in eukaryotes may reflect an underappreciated method of host resistance to infection. This work demonstrates for the first time that an endogenous host protein encoded by a gene that has been naturally acquired from a virus and fixed in a eukaryote can interfere with the replication of a related virus and do so by negative complementation. PMID- 30280046 TI - Investigating the relationship between intergroup physical contact and attitudes towards foreigners: the mediating role of quality of intergroup contact. AB - Recent research has shown that a brief, casual touch administered by an outgroup member reduces prejudice towards the group to which the toucher belongs. In this study, we take the research on physical contact and prejudice a step further by addressing the relation between individuals' amount of Experienced Intergroup Physical Contact (EIPC), across distinct contexts and involving different body parts, and attitudes towards foreign people. Specifically, we hypothesized that the amount of EIPC would be positively associated with both quantity and quality of intergroup contact, but that only quality would mediate the relationship between the amount of EIPC and outgroup attitudes, quality being more directly linked to the evaluative component of outgroup attitudes. To attain this aim, we asked participants to self-report the amount of EIPC, the quantity and quality of their intergroup contact and their attitudes towards foreign people. Consistent with our hypothesis: (1) as EIPC increased, positive attitudes towards foreign people increased; (2) higher levels of EIPC were associated with better quality and higher quantity of intergroup contact; (3) only quality of intergroup contact mediated the relationship between the amount of EIPC and attitudes towards foreign people. Results were discussed in relation to research on intergroup contact and physical contact. PMID- 30280047 TI - Meta-analysis of northeast Atlantic marine taxa shows contrasting phylogeographic patterns following post-LGM expansions. AB - Background: Comparative phylogeography enables the study of historical and evolutionary processes that have contributed to shaping patterns of contemporary genetic diversity across co-distributed species. In this study, we explored genetic structure and historical demography in a range of coastal marine species across the northeast Atlantic to assess whether there are commonalities in phylogeographic patterns across taxa and to evaluate whether the timings of population expansions were linked to the Last Glacial Maximum (LGM). Methods: A literature search was conducted using Web of Science. Search terms were chosen to maximise the inclusion of articles reporting on population structure and phylogeography from the northeast Atlantic; titles and abstracts were screened to identify suitable articles within the scope of this study. Given the proven utility of mtDNA in comparative phylogeography and the availability of these data in the public domain, a meta-analysis was conducted using published mtDNA gene sequences. A standardised methodology was implemented to ensure that the genealogy and demographic history of all mtDNA datasets were reanalysed in a consistent and directly comparable manner. Results: Mitochondrial DNA datasets were built for 21 species. The meta-analysis revealed significant population differentiation in 16 species and four main types of haplotype network were found, with haplotypes in some species unique to specific geographical locations. A signal of rapid expansion was detected in 16 species, whereas five species showed evidence of a stable population size. Corrected mutation rates indicated that the majority of expansions were estimated to have occurred after the earliest estimate for the LGM (~26.5 Kyr), while few expansions were estimated to have pre-dated the LGM. Conclusion: This study suggests that post-LGM expansion appeared to be common in a range of marine taxa, supporting the concept of rapid expansions after the LGM as the ice sheets started to retreat. However, despite the commonality of expansion patterns in many of these taxa, phylogeographic patterns appear to differ in the species included in this study. This suggests that species-specific evolutionary processes, as well as historical events, have likely influenced the distribution of genetic diversity of marine taxa in the northeast Atlantic. PMID- 30280048 TI - Functions of Candida albicans cell wall glycosidases Dfg5p and Dcw1p in biofilm formation and HOG MAPK pathway. AB - Background: Candida albicans is a commensal fungus that inhabits the oral mucosal surface and causes oral and systemic candidiasis. Oral candidiasis most commonly occurs in patients with AIDS, denture wearers and newborn children. Systemic candidiasis occurs mainly in immunocompromised patients and patients admitted to hospitals for prolonged periods. C. albicans homologous genes, DFG5 and DCW1, encode for two closely related cell wall proteins with putative glycosyltransferase enzyme activity and C-terminal GPI-anchors. Past studies have shown that individual DFG5 and DCW1 mutations are viable but simultaneous deletion of DFG5 and DCW1 in C. albicans results in lethality. However, the exact functions of these cell wall based enzymes, which represent potential drug targets, are not understood. Methods: C. albicans DFG5/DCW1 heterologous and conditional double mutant strains were assessed for growth and biofilm formation in comparison to wild type and parental strains. Cell wall and heat stress susceptibility of the mutant and control strains were assessed using agar spotting assays. Growth was assessed under normal and osmotic stress conditions along with light microscopy imaging. Biofilm dry weight and microscopic imaging analysis of biofilms was performed. Hypha formation in response to serum was analyzed using light microscopy imaging. Western blot analysis of mutant strains and control strains was performed to assess Hog1 basal levels and phosphorylation status. Results: Analysis of the heterologous mutants indicated that Dfg5p is more important for growth while Dcw1p appeared to play a role in cell wall integrity response. The conditional double mutant was observed to be less resistant to cell wall stress. However, growth of the mutants was similar under control and osmotic stress conditions. The mutants were also able to grow similar to wild type under heat stress. Biofilm formation was reduced in the mutants where DFG5 was deleted or suppressed. Hyphal morphogenesis was reduced although germ tube formation was observed in the biofilms of the mutant strains. Basal Hog1 protein levels were reduced or absent in the DFG5 and DCW1 mutants. However, osmotic stress was able to induce Hog1 protein levels comparable to wild type. Hog1 phosphorylation appeared to be slightly reduced although not significantly. In addition to biofilm assays, serum dose response imaging analysis indicated that hyphae formation in DFG5 and DCW1 mutants was defective. Conclusions: These data indicate that DFG5 and DCW1 are required for hyphal morphogenesis and biofilm formation in C. albicans. These functions may be regulated via basal Hog1 MAPK which is required for transcriptional regulation of chitin synthesis. PMID- 30280049 TI - Modeled larval connectivity of a multi-species reef fish and invertebrate assemblage off the coast of Moloka'i, Hawai'i. AB - We use a novel individual-based model (IBM) to simulate larval dispersal around the island of Moloka'i in the Hawaiian Archipelago. Our model uses ocean current output from the Massachusetts Institute of Technology general circulation model (MITgcm) as well as biological data on four invertebrate and seven fish species of management relevance to produce connectivity maps among sites around the island of Moloka'i. These 11 species span the range of life history characteristics of Hawaiian coral reef species and show different spatial and temporal patterns of connectivity as a result. As expected, the longer the pelagic larval duration (PLD), the greater the proportion of larvae that disperse longer distances, but regardless of PLD (3-270 d) most successful dispersal occurs either over short distances within an island (<30 km) or to adjacent islands (50-125 km). Again, regardless of PLD, around the island of Moloka'i, connectivity tends to be greatest among sites along the same coastline and exchange between northward, southward, eastward and westward-facing shores is limited. Using a graph-theoretic approach to visualize the data, we highlight that the eastern side of the island tends to show the greatest out-degree and betweenness centrality, which indicate important larval sources and connectivity pathways for the rest of the island. The marine protected area surrounding Kalaupapa National Historical Park emerges as a potential source for between island larval connections, and the west coast of the Park is one of the few regions on Moloka'i that acts as a net larval source across all species. Using this IBM and visualization approach reveals patterns of exchange between habitat regions and highlights critical larval sources and multi-generational pathways to indicate priority areas for marine resource managers. PMID- 30280050 TI - Sunset Yellow and Allura Red modulate Bcl2 and COX2 expression levels and confer oxidative stress-mediated renal and hepatic toxicity in male rats. AB - Studies on the adverse health effects caused by azo dyes are insufficient and quite contradictory. This work aims to investigate the possible toxic effect of two types of widely used food additives, Sunset Yellow and Allura Red, by assessing the physiological, histopathological and ultrastructural changes in the liver and kidney. Also, we investigated the genotoxic effect of both dyes on white blood cells. Thirty adult male albino rats were divided into three groups of 10 animals each: control (received water), Sunset Yellow-treated (2.5 mg/kg body weight) and Allura Red-treated (seven mg/kg body weight). The doses were orally applied for 4 weeks. Our results indicated an increase in the biochemical markers of hepatic and renal function (Aspartate aminotransferase, alanine aminotransferase, urea, uric acid and creatinine) in animals administered with the azo dyes. We also observed a noticeable increase in MDA and a marked decrease in total antioxidant levels in azo dye-treated animals compared to controls. Conversely, both dyes adversely affected the liver and kidney of albino rats and altered their histological and fine structure, with downregulation of Bcl2 and upregulation of COX2 expression. Our comet assay results showed a significant elevation in the fold change of tail moment in response to application of Sunset Yellow but not Allura Red. Collectively, we show that Sunset Yellow and Allura Red cause histopathological and physiological aberrations in the liver and kidney of male Wistar albino rats. Moreover, Sunset Yellow but not Allura Red induces a potential genotoxic effect. PMID- 30280051 TI - Influence of sports expertise level on attention in multiple object tracking. AB - Background: This study aimed to investigate whether performance in a multiple object tracking (MOT) task could be improved incrementally with sports expertise, and whether differences between experienced and less experienced athletes, or non athletes, were modulated by load. Methods: We asked 22 elite and 20 intermediate basketball players, and 23 non-athletes, to perform an MOT task under three attentional load conditions (two, three, and four targets). Accuracies were analyzed to examine whether different levels of sports expertise influence MOT task performance. Results: The elite athletes displayed better tracking performance compared with the intermediate or non-athletes when tracking three or four targets. However, no significant difference was found between the intermediate athletes and the non-athletes. Further, no differences were observed among the three groups when tracking two targets. Discussion: The results suggest that the effects of expertise in team ball sports could transfer to a non-sports specific attention task. These transfer effects to general cognitive functions occur only in elite athletes with extensive training under higher attentional load. PMID- 30280052 TI - Hepatocellular Carcinoma Occurrence and Recurrence in Hepatitis C-infected Patients Treated with Direct-acting Antivirals. AB - Introduction Multiple studies have shown the efficacy of the new direct-acting antivirals (DAAs) with a cure rate of over 90% in hepatitis C virus (HCV) infected patients. Some recently published studies have suggested an increased incidence of de novo and recurrent hepatocellular carcinoma (HCC) in cirrhotic patients in sustained virological response (SVR) after completing therapy. A possible mechanism is the breakdown of immune surveillance after starting DAAs. We report a retrospective analysis on a population of chronic HCV infected patients, with and without a prior history of HCC, who developed HCC after receiving DAAs in the hope of adding to existing literature and in pursuit of greater clarity into this emerging concern with DAAs. Methods We analyzed 497 HCV infected patients who were treated with DAAs, or a combination of DAA with interferon, from January 2014 to April 2017 at the Veterans Medical Center, Oklahoma City. Descriptive analysis, including the mean and standard deviation for different variables, was used. The cohort was divided into two groups: cirrhotic and non-cirrhotic. The analysis was run in the cirrhotic group between the subgroups who developed HCC and who did not. Results Data from a total of 233 cirrhotic patients were analyzed. We further subdivided these patients into those who eventually were diagnosed with HCC (group 1) and those who were not (group 2). These subgroups were comparable in regards to race, gender, baseline serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), platelets, sodium, HCV genotypes, and pretreatment viral load. All patients completed therapy. The rate of SVR was much lower in group 1 compared to group 2 (62.5% vs 88.94%, p = 0.002), respectively. Model End-stage Liver Disease (MELD) score, Child-Turcotte-Pugh (CTP) score, and Fibrosis-4 (FIB-4) score were higher in the group that developed HCC. The average time period (weeks) from DAA therapy to HCC diagnosis was 48.2 weeks. The remaining 264 non-cirrhotic patients had no reported cases of HCC. Conclusion From a total of 497 treated HCV-infected patients, 233 (46.88 %) had cirrhosis, out of which 16 (6.86%) were reported to develop HCC during or after DAA therapy was initiated. The remaining 217 (93.1%) cirrhotic patients did not develop HCC. As per our comparison, achieving SVR in cirrhotic patients should not preclude HCC screening, and more studies are needed to assess the risk of HCC in patients who achieve SVR but have a high FIB-4 score. In fact, patients who do not achieve SVR may be at a higher risk of eventually developing HCC and may be candidates for closer surveillance. PMID- 30280054 TI - Persistent Alopecia in a Breast Cancer Patient Following Taxane Chemotherapy and Adjuvant Endocrine Therapy: Case Report and Review of Post-treatment Hair Loss in Oncology Patients with Breast Cancer. AB - Taxane chemotherapy and adjuvant endocrine therapy are commonly used in breast cancer patients following surgery. We describe a 59-year-old woman with a triple positive invasive right breast cancer that was treated with surgery, radiation, chemotherapy, and adjuvant hormonal therapy. She subsequently developed scalp alopecia, with histopathological features of both androgenetic alopecia and alopecia areata; the hair loss did not resolve after completion of her chemotherapy. Significant clinical improvement was observed with topical minoxidil therapy. PubMed was searched for the following terms: alopecia, breast, cancer, chemotherapy, endocrine, hair, loss, minoxidil, permanent, and taxane. The papers containing these terms and their references were reviewed. Temporary hair loss is frequently observed following taxane chemotherapy; however, albeit uncommon, persistent or permanent alopecia may occur in women with breast cancer who have been treated with taxane chemotherapy and endocrine therapy. It may be reasonable to initiate therapy with topical minoxidil in breast cancer patients who develop alopecia after treatment with either taxane chemotherapy or endocrine therapy alone or both. PMID- 30280053 TI - Impact of Neoadjuvant Chemotherapy on the Administration of Concurrent Chemoradiation for Locally Advanced Nasopharyngeal Carcinoma. AB - Objectives The standard of care for locally advanced nasopharyngeal carcinoma (NPC) is concurrent cisplatin chemoradiotherapy. Neoadjuvant chemotherapy can be administered to downsize tumors before concurrent treatment to optimize radiation volumes. Our hypothesis was that the use of cisplatin in the neoadjuvant phase could limit the amount of cisplatin that patients could tolerate in the concurrent phase of treatment. Methods This is a retrospective analysis of Canadian NPC patients who received neoadjuvant chemotherapy with the intention to downsize locally advanced tumors prior to concurrent cisplatin plus radiation. Baseline demographic and treatment data were obtained from institutional databases and chart review; all data were analyzed with SPSS (SPSS Inc. Released 2005. SPSS for Windows, Version 14.0. Chicago: SPSS Inc.) Overall survival (OS), disease-specific survival (DSS), and local/regional relapse-free survival (LRRFS) were analyzed using Kaplan-Meier survival functions. Univariate and multivariate models were used to determine factors associated with the total dose of concurrent chemotherapy. Results Forty-six patients were identified as receiving neoadjuvant chemotherapy before concurrent chemoradiotherapy. In the univariate and multivariate analyses of patients who received concurrent chemotherapy, receiving over 200 mg/m2 concurrent cisplatin with radiation was associated with a higher neoadjuvant dose of chemotherapy received. The median follow-up time was 2.6 years (range, 0.17 years to 10.6 years). At three years, the OS was 83%, DSS was 86%, and LRRFS was 74%. Conclusions NPC patients have been treated with neoadjuvant chemotherapy at this center with favorable outcomes. Most patients could tolerate concurrent chemotherapy after radiotherapy. Receiving higher doses of concurrent chemotherapy was associated with also having higher doses of neoadjuvant cisplatin. This suggests that neoadjuvant cisplatin is not a limiting factor in the delivery of full-dose concurrent chemotherapy. PMID- 30280055 TI - Persistent Psychosis due to Single Dose of Ecstasy. AB - Ecstasy, a popular drug among the younger generation, the primary psychoactive component of which is 3,4-Methylenedioxymethamphetamine (MDMA), is rarely known to have acute psychiatric effects and when it does, it is usually short term. We describe a patient who presented to the emergency room in a psychotic state after using ecstasy recreationally. Given his aggressive behavior in the community and risk for self-harm, he was emergently hospitalized to ensure safety. He developed persistent psychotic symptoms (delusions) after one dose of recreational MDMA and the team had the opportunity to observe, monitor, and treat his psychosis. This case along with few other documented cases highlights the gaps in research about the chronic, persistent effects and long-term consequences of MDMA. It also suggests that neuropsychiatric symptoms may not be readily reversible after cessation of use. There is an emphasis on the need for physicians to inquire about MDMA use and include it in toxicology screenings and as a potential differential diagnosis. PMID- 30280056 TI - Comparative Evaluation of the Remineralization Potential of Monofluorophosphate, Casein Phosphopeptide-Amorphous Calcium Phosphate and Calcium Sodium Phosphosilicate on Demineralized Enamel Lesions: An In Vitro Study. AB - AIM: The aim of the study is to compare the remineralization potential of monofluorophosphate, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), and calcium sodium phosphosilicate on demineralized enamel lesions. MATERIALS AND METHODS: Enamel sections from 30 sound human premolar crowns were prepared and sectioned into quadrants. Early enamel lesions were created in each sample by immersion in a demineralizing solution for 72 hours. Of the four sections, the first quadrant (A) was not given any surface treatment, the second quadrant (B) was treated with monofluorophosphate dentifrice, the third (C) was treated with casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), and the fourth (D) was treated with calcium sodium phosphosilicate while being subjected to a five day pH cycling protocol. The sections were further cross-sectioned to expose the lesion depth and were then viewed under the confocal laser scanning microscope after staining with 0.1 mM rhodamine B dye for 24 hours. The two parameters evaluated were the cross-sectional demineralized lesion area and total fluorescence. RESULTS: Amongst the dentifrices tested, the lowest values for lesion area and total fluorescence were recorded by calcium sodium phosphosilicate (3874.1 u2 and 107282.6, respectively), followed by casein phosphopeptide-amorphous calcium phosphate (5776.6 u2 and 129470.8) and then by monofluorophosphate dentifrice (7371.2 u2 and 233765.9) in increasing order. The highest values for lesion area and total fluorescence were recorded by the no treatment group (16449.2 u2 and 759743.1). One-way analysis of variance (ANOVA) showed significant variations (p<0.01) between the groups and Scheffe multiple comparisons confirmed the significance (p<0.01) of intergroup variations. CONCLUSION: The results of this study suggest that, among the three agents tested, calcium sodium phosphosilicate is the most effective remineralizing agent followed by casein phosphopeptide-amorphous calcium phosphate. Monofluorophosphate is the least effective remineralizing agent when tested under the conditions mentioned in this study. PMID- 30280057 TI - Antidromic Atrioventricular Reentrant Tachycardia Dependent on a Unidirectional Left Anterior Accessory Pathway Mimicking Peri-mitral Ventricular Tachycardia: Successful Ablation via a Transseptal Approach. AB - Antidromic atrioventricular reentrant tachycardia (aAVRT) is rare compared to orthodromic atrioventricular reentrant tachycardia (oAVRT). An aAVRT that is dependent on a unidirectional, decremental accessory pathway (AP) is even rarer. Idiopathic ventricular tachycardias (iVT) that have benign prognoses and respond well to medical therapy can be confused with aAVRTs dependent on APs having ventricular insertion sites close to the iVT focus and have a real risk of sudden death. The preferred approach of ablation for such tachycardias with anterograde conduction only is a retrograde aortic approach, which facilitates the mapping of the earliest ventricular activation during atrial pacing or tachycardia from the ventricular side. This, however, necessitates access to the arterial system with accompanying complications. We describe herein the case of a wide complex tachycardia, which was treated initially as VT with intravenous lidocaine. The baseline electrocardiogram (ECG) did not show preexcitation. An electrophysiology study (EPS) revealed a left anterior AP that conducted anterograde only. AVRT was easily inducible at a cycle length of 290 ms. Successful ablation was undertaken via the transseptal approach without recurrence. PMID- 30280059 TI - Clinical Context Generation for Imaging: A Design Thinking-based Analysis of a Pilot Project. AB - Design Thinking is a method for the practical, creative resolution of problems using the strategies used during the process of designing. It is increasingly being used in Medical enterprise to develop a solution-based approach to identify ambiguous problems and create alternative paths to the solution. We faced several challenges in the development of a clinical context generation tool and in this article, we retrospectively assess the usefulness of a Design Thinking approach had it been applied to a project related to Medical Imaging-related clinical context generation. PMID- 30280058 TI - Vitamin C: A Preventative, Therapeutic Agent Against Helicobacter pylori. AB - The treatment of Helicobacter pylori (H. pylori) induced infections using antibiotic therapies is clinically well accepted; however, using a noninvasive approach with the implementation of therapeutic agents such as vitamin C is not well investigated. Vitamin C has certain characteristics, which allow for it to be considered as a potential treatment option for patients with H. pylori infections. Vitamin C's hostility and mechanism of action towards H. pylori infection in peptic ulcer disease can be classified into two categories: as a preventative agent and alternatively as a therapeutic agent. Preventatively vitamin C acts as a biological antioxidant as well as an immune boosting agent, while therapeutically it acts as an inhibitor of urease, a potential collagen synthesizing agent, and a stimulant in prostaglandin synthesis. As a result, the dosage of vitamin C should be highly regulated. Furthermore, numerous studies have shown that vitamin C supplementation if taken with antibiotics can increase the efficiency of the treatment leading to an increased possibility of eradication of H. pylori in infected individuals. This paper will investigate the recent studies that show different mechanisms through which vitamin C can be used as a preventative or a therapeutic agent for the treatment of H. pylori related infections. PMID- 30280060 TI - An Overview of Our Current Understanding of Diabetic Macular Ischemia (DMI). AB - Diabetic macular ischemia (DMI) is a troublesome complication of diabetes mellitus. The pathogenesis, progression, consequences, and treatment options for this disease are still poorly understood. However, it is believed that this complication is associated with several risk factors like poor glycemic control and high blood pressure. Two factors have been identified in the pathogenesis of the disease that play pivotal roles in disease development and progression. One of these factors includes extensive damage to the microvasculature of the retina. This includes narrowing of the vascular lumen and extensive damage to the endothelial cells, pericytes and the extracellular matrix. The second factor includes extensive damage to the neurosensory layer of the retina. DMI is always associated with other complications of diabetic retinopathy like retinal edema, so it is very difficult to find an isolated case of DMI. Moreover, the condition is also very rare making it very difficult to study and diagnose. However, a number of diagnostic tests like optical coherence tomography (OCT), fluorescence angiography (FA), and perimetry can be used as tools for the early detection of DMI. Since this disease damages the retina, loss of vision is an inevitable consequence that can progressively worsen over time. Also, DMI has been implicated as a risk factor for retinal edema and progressive diabetic retinopathy. Until now, no defined treatment protocol has been devised. The only available treatments focus on the management of risk factors (hyperglycemia and hypertension). Still, many aspects of DMI remain poorly studied and understood. This review paper aims to add to our current understanding of diabetic macular ischemia (DMI).

AB - Papillary muscle rupture after acute myocardial infarction (AMI) is a dreadful complication and it is associated with five percent of deaths following AMI. Surgery is the recommended treatment of choice; however, it is usually deferred due to the high risk of mortality. MitraClip implantation using a transcatheter approach is an alternative option for patients with severe mitral regurgitation (MR) following AMI or those with high operative risk. We report a case of a 68 year-old male patient who developed severe MR secondary to AMI and underwent successful mitral valve repair using the MitraClip device. PMID- 30280063 TI - How To Be a Leader: A Course for Residents. AB - BACKGROUND: Physicians are required to assume a leadership role as part of their career. For most, this is not an innate characteristic and must be developed throughout their medical training. There are few residency courses designed to assist in the enhancement of these leadership skills. We created and implemented a novel course on leadership, utilizing weekly presentations designed to stimulate discussions and improve the leadership qualities of trainees. METHODS: Senior residents provided leadership lectures stimulated by assigned readings from the book "The Founding Fathers on Leadership." The traits and characteristics demonstrated throughout course readings and discussions were subsequently incorporated into everyday resident activities. Baseline and post course survey responses were evaluated to assess changes in leadership qualities. RESULTS: Seven senior (postgraduate year (PGY) 3-5) participated as course leaders. All seven filled out pre- and post-course surveys. Seventeen junior residents (PGY 1-2) were involved as audience members. Significant pre- and post course differences were noted in the following areas: feelings of increased encouragement of personal development (4.86 vs. 5.43, p=0.03); increased team participation in decision-making (4.00 vs. 4.57, p=0.03); increased ease of obtaining answers to difficult questions (4.57 vs. 5.23, p=0.047); increased team member work (4.86 vs. 5.71, p=0.047), and a sense of leading a more balanced life (3.86 vs. 4.43, p=0.03). CONCLUSION: The initiation of a novel leadership course for senior surgical residents led to an enjoyable experience, resulting in enhanced leadership skills for all participants. We believe this process resulted in a more cohesive, efficient, communicative, and supportive residency program. PMID- 30280062 TI - Endogenous Endophthalmitis: A Five-year Review of Cases at the Raja Perempuan Zainab II Hospital, Kelantan, Malaysia. AB - Background Endogenous endophthalmitis (EE) is a type of intraocular inflammation secondary to hematogenous spread from a distant infective source within the body and usually occurs in immunocompromised patients. Objectives The aim of this study was to profile the patient characteristics, sources of infection, microbial profiles, and visual outcomes of patients with EE in Raja Perempuan Zainab II Hospital in Kelantan, Malaysia. Materials and methods Data from 18 eyes of 17 patients diagnosed with EE and admitted to the eye ward of Raja Perempuan Zainab II Hospital from January 2012 to December 2016 were retrospectively reviewed. Factors analyzed included patient age, sources of infection, visual acuity, microbial profiles, and treatment outcomes. Results The mean age of the 17 patients was 53.2 years. Twelve patients (70.6%) had EE of left eye, four (23.5%) had EE of right eye, and one (5.9%) had EE involving both the eyes. Sixteen patients (91.1%) had at least one predisposing condition, the most common of which was diabetes mellitus in 15 patients (88.2%). A source of infection was identified in 12 of the 17 patients, with urinary tract infection being the most common (five patients, 29.4%). Organisms were successfully isolated from 10 (58.8%) patients, including seven (41.2%) with Gram-negative and three (17.6%) with Gram-positive organisms. All patients presented with a visual acuity worse than 6/60. Nine (52.9%) patients underwent vitrectomy, with only two of these patients achieving a final visual acuity better than 6/60. Eleven patients became nonperceptive to light, with four of them undergoing evisceration. Conclusions EE is a rare but often devastating ocular condition. Visual outcomes are often poor especially in patients infected with Gram-negative bacteria.

AB - Intracranial schwannomas account for 8% of all intracranial tumors, out of which 90% are acoustic schwannomas. Other rare varieties include trigeminal melanotic schwannomas that account for 0.2% of all intracranial tumors. Melanotic schwannomas are intracranial tumors that are heavily pigmented due to the presence of melanin. The most common origination of the tumor involves being confined to Meckel's cave, presenting with features of trigeminal neuralgia, neurasthenia, and numbness. We report a case of a 48-year-old male presenting with dysarthria, left-sided hemiparesis, dysphagia, and headache for the past six months. Magnetic resonance imaging (MRI) confirmed a mass in the right cerebellopontine (CP) angle, which extended into the middle cranial fossa. Our case is interesting because it is the fourth case reported worldwide. PMID- 30280065 TI - The Incisive Canal: A Comprehensive Review. AB - The incisive canal, also known as the nasopalatine canal, is an interosseous conduit through the anterior maxilla connecting the oral and nasal cavities. Within this canal lies the nasopalatine nerve and the vascular anastomosis between the greater palatine and sphenopalatine arteries. The embryology of the canal has led to interesting theories explaining its function. Efforts have been made to describe the morphometrics of the incisive canal by radiologic evaluation across sex and ethnicities. This paper aims to review the current literature on the embryology, anatomy, and clinical relevance of the incisive canal. PMID- 30280066 TI - Netherton Syndrome: A Case Report and Review of Literature. AB - Netherton syndrome (NS) is a rare autosomal recessive disorder characterized by a triad of congenital ichthyosiform erythroderma (CIE) or ichthyosis linearis circumflexa (ILC), hair shaft abnormalities, and atopic diathesis (elevated serum IgE ). We report a case of a two-year-old boy presented with intractable pruritus, scaling, dry skin and generalized eczematous lesions resistant to atopic dermatitis therapy. Netherton syndrome misdiagnosed as atopic dermatitis due to the presence of eczematous skin lesions and allergic problems. The family counseled about the diagnosis and need of genetic testing for confirmation, but they refused for genetic testing. The patient got treatment with topical corticosteroids and skin moisturizers. There is no cure or satisfactory treatment currently available for NS. Further understanding of the underlying pathophysiology of integumentary changes will lead to more effective treatment. Netherton syndrome should be in the differential diagnosis when characteristic skin manifestation of CIE or ILC, and elevated serum IgE present. PMID- 30280067 TI - Laboratory Evaluation of a Robotic Operative Microscope - Visualization Platform for Neurosurgery. AB - Background We assessed a new robotic visualization platform with novel user control features and compared its performance to the previous model of operative microscope. Methods In a neurosurgery research laboratory, we performed anatomical dissections and assessed robotic, exoscopic, endoscopic, fluorescence functionality. Usability and functionality were tested in the operating room over 1 year. Results The robotic microscope showed higher sensitivity for fluorescein sodium, higher detail in non-fluorescent background, and recorded/presented pictures with color quality similar to observation through the oculars. PpIX visualization was comparable to the previous microscope. Near-infrared indocyanine green imaging 3-step replay allowed for more convenient accurate assessment of blood flow. Point lock and pivot point functions were used in dissections to create 3D virtual reality microsurgical anatomy demonstrations. Pivot point control was particularly useful in deep surgical corridors with dynamic retraction. 3D exoscopic function was successfully used in brain tumor and spine cases. Endoscopic assistance was used for around-the-corner views in minimally invasive approaches. We present illustrative cases highlighting utility and new ways to control the operative microscope. Conclusion Improvements of the robotic visualization platform include intraoperative fluorescence visualization using FNa, integrated micro-inspection tool, improved ocular imaging clarity, and exoscopic mode. New robotic movements positively assist the surgeon and provide improved ergonomics and a greater level of intraoperative comfort, with the potential to increase the viewing quality. New operational modes also allow significant impact for anatomy instruction. With the increasing number and complexity of functions, surgeons should receive additional training in order to avail themselves of the advantages of the numerous novel features. PMID- 30280068 TI - Successful Transplantation of Pediatric Kidneys Despite Vascular Injuries. AB - The gap between the kidney transplant recipient list and the number of organs available for transplantation continues to grow. Pediatric donors help fill a small and valuable portion of that gap. Normally these organs are transplanted en bloc by closing the proximal vascular caps and using the distal aorta and distal inferior vena cava (IVC) for inflow. They are however commonly injured during the donor operation making the standard operation for pediatric en-bloc transplantation not possible. This case report presents two cases in which injured small pediatric kidneys were transplanted successfully in adult patients. We are presenting two examples of common vascular injuries to small pediatric kidneys, one venous and one arterial. In both scenarios, the kidneys were transplanted using a modification to the standard technique. The two kidneys were separated and the technique of implantation was modified to allow safe transplantation. This way we were able to transplant both kidneys successfully and using a reproducible methodology. Both recipients were young adults. There were no surgical complications. PMID- 30280069 TI - Subcutaneous Fat Necrosis and Hypercalcemia After Therapeutic Hypothermia in Patients With Hypoxic-ischemic Encephalopathy: A Case Series. AB - Therapeutic hypothermia (TH) is provided to newborns with moderate to severe hypoxic-ischemic encephalopathy (HIE) to improve survival and long-term neurodevelopmental outcomes. Although the benefits certainly outweigh the risks associated with therapeutic hypothermia, it is important to be mindful of potential rare side effects in the background of asphyxia-related injury to various body organs. One of those side effects includes subcutaneous fat necrosis (SCFN) that can occur in term newborns after perinatal hypoxia-ischemia or other stressing factors such as systemic hypothermia. It is usually a self-limited condition, however, in some cases, it can lead to severe hypercalcemia. We report three such cases of SCFN in newborns with HIE treated with TH. Due to potential long-term complications, such as metastatic calcifications, caregivers should be informed about this potential complication prior to discharge from hospital so that they can help diagnose or continue to monitor cases of severe hypercalcemia. PMID- 30280071 TI - The Impact of the Hippocratic Oath in 2018: The Conflict of the Ideal of the Physician, the Knowledgeable Humanitarian, Versus the Corporate Medical Allegiance to Financial Models Contributes to Burnout. AB - The tradition in medical school includes taking the Hippocratic Oath usually at graduation. The purpose of this review is to examine what that oath has been, what forms it currently has, and the implications for physicians in today's healthcare environment. The changes in health economics affect physicians as they try to follow the oath's allegiance to the individual patient's needs. At times, this goal conflicts with the perspective of the financial world's controls of insurance companies and medical groups and institutions. This difference of the physicians' ethical perspectives from the business leaders regarding the philosophy of the value of the individual's health and life may be related to some aspect of physician burnout. PMID- 30280070 TI - Outcomes of Metastatic Brain Lesions Treated with Radioactive Cs-131 Seeds after Surgery: Experience from One Institution. AB - Introduction Brain metastases are common in patients with advanced systemic cancer and often recur despite treatment with surgical resection and radiotherapy. Whole brain radiation therapy (WBRT) and stereotactic radiosurgery (SRS) have significantly improved local control rates but are limited by complications including neurocognitive deficits and radiation necrosis. These risks can be higher in the re-irradiation setting. Brachytherapy may be an alternative method of additional targeted adjuvant radiotherapy with acceptable rates of toxicity. Methods A retrospective chart review of all patients undergoing resection for metastatic brain lesions and permanent low-dose rate Cs 131 brachytherapy was performed for one institution over a 10-year period. All patients had previous radiation therapy already and, after surgery, were followed with imaging every three months. Patient demographics, disease characteristics, intracranial disease, peri- and post-operative complications, and outcomes were recorded. The primary outcome of interest was local tumor recurrence at the site of brachytherapy while secondary outcomes included distant disease progression (within the brain) and complications such as radiation necrosis. Results During the study period, nine cases of individual patients met inclusion criteria. The median preoperative lesion diameter was 3 cm (0.8-4.1). The median overall survival after surgery and brachytherapy was 10.3 months, after excluding two patients who were lost to follow-up. Six of nine patients had no local recurrence, while three patients had development or progression of distant lesions. No patients experienced acute or delayed complications. Conclusion Cs 131 brachytherapy is a promising alternative method for controlling brain metastases after previous radiation interventions and surgical resection. In this case series, there were no incidences of local tumor recurrence or complications such as radiation necrosis.

PMID- 30280073 TI - Natural History of Isolated Skull Fractures in Children. AB - Head injury is the most common cause of neurologic disability and mortality in children. We had hypothesized that in children with isolated skull fractures (SFs) and a normal neurological examination on presentation, the risk of neurosurgical intervention is very low. We retrospectively reviewed the medical records of all children aged six to sixteen years presenting to our Level 1 trauma center with traumatic brain injuries between January 1, 2006 and December 31, 2014. We also analyzed the National Trauma Data Bank (NTDB) research data set for the years 2012-2014 using the same metrics. During this study period, our center admitted 575 children with skull fractures, 197 of which were isolated (no associated intracranial lesions (ICLs)). Of the 197 patients with isolated SFs, 155 had a normal neurological examination at presentation. In these patients, there were no fatalities and only three (1.9%) required surgery, all for the elevation of the depressed skull fracture. Analyzing the NTDB yielded similar results. In 5,194 children with isolated SFs and a normal neurological examination on presentation, there were no fatalities and 249 (4.8%) required neurosurgical intervention, almost all involving craniotomy/craniectomy and/or elevation of the SF segments. In conclusion, children with non-depressed isolated skull fractures and a normal Glasgow coma scale (GCS) at the time of initial presentation are at extremely low risk of death or needing neurosurgical intervention. PMID- 30280074 TI - Bacterial lactase genes diversity in intestinal mucosa of dysbacterial diarrhea mice treated with Qiweibaizhu powder. AB - The current research tried to investigate the effect of Qiweibaizhu powder (QWBZP) on intestinal mucosa bacterial lactase gene from dysbacterial diarrhea mice, as the good therapeutic mechanism of QWBZP on antibiotics-induced diarrhea. Dysbacterial diarrhea mice model was constructed by gastric perfusion with mixture of cephradine capsules and gentamicin sulfate (23.33 mL kg-1 day-1) for 5 days. After the success of establishing diarrhea, the mice in treatment group were gavaged with QWBZP for 3 days. Intestinal mucosa in each group was collected, and diversity of bacterial lactase genes in intestinal mucosa of mice was carried out by Miseq metagenome sequencing. The results showed the Chao1, ACE, Simpson and Shannon indices in treatment group were lower than model group and were similar to control group. The same result was obtained from the operational taxonomic units (OTUs). There were 298, 435 and 254 OTUs in the control group, model group and treatment group, respectively. Principal component analysis (PCA) indicated that samples distribution in both normal and treatment groups were relatively intensive, distances among individuals were small, while opposite results were observed in model group. Moreover, antibiotics increased the diversity and abundance of bacterial lactase genes at phylum and genus levels. However, they decreased and were similar to control group after treating with QWBZP. Our results indicate that QWBZP has a positive effect on the recovery of bacterial lactase gene diversity to normal level. In addition, QWBZP increase the abundance of Lysobacter and Eukaryota.

AB - A 32-year-old woman presented with amenorrhea after a normal childbirth and subsequently developed nephrotic syndrome. Renal biopsy showed a thrombotic microangiopathy (TMA)-like glomerular lesion with deposits of immunoglobulins, complements, and fibrinogen. Increased serum levels of the beta subunit of human chorionic gonadotropin, abnormal uterine findings from imaging studies, and endometrial biopsy findings suggested gestational trophoblastic disease. She was diagnosed with a placental site trophoblastic tumor (PSTT) after hysterectomy and, following treatment, her proteinuria disappeared. Follow-up renal biopsy showed the disappearance of the TMA-like lesion. To our knowledge, this is the first case report of the pathological remission of renal disease associated with PSTT. PMID- 30280076 TI - A Comparison of Three Different Methods of Fixation in the Management of Thoracolumbar Fractures. AB - Background: Management of thoracolumbar fractures remains controversial in the literature. The primary aims of this study were to assess different levels of fixation with respect to radiological outcomes in terms of fracture reduction and future loss of correction. Methods: This is a single center, retrospective study. Fifty-five patients presenting with thoracolumbar fractures between January 2012 and December 2015 were analyzed in the study. The levels of fixation were divided in 3 groups: 1 vertebra above and 1 below the fracture (1/1), 2 above and 2 below (2/2), and 2 above and 1 below (2/1). Results: The most common mechanism was high fall injury, and the most common vertebra L1. Burst fractures were the ones with the highest incidence. The 2/2 fixation achieved the best reduction of the fracture, but with no statistical significance. The correction is maintained better by the 2/2 fixation, but there is no statistical difference compared to the other fixations. Insertion of screws at the fracture level did not improve outcomes. Conclusion: The data of this study identified a trend toward better radiological outcomes for fracture reduction and maintenance of the correction in the 2/2 fixations. However, these results are not statistically significant. Future multicenter prospective clinical trials are needed in order to agree on the ideal management and method of fixation for thoracolumbar fractures. PMID- 30280077 TI - Anatomical Modifications during the Lateral Transpsoas Approach to the Lumbar Spine. The Impact of Vertebral Rotation. AB - Background: We investigated impact of vertebral axial rotation on neurovascular anatomy in adult spinal deformity (ASD) patients and provided recommendations on the approach based on degree of axial rotation. In order to isolate vertebral rotation (VR) impact from the superimposed degenerative cascade observed in adulthood, adolescent idiopathic scoliosis (AIS) patients were analyzed. Methods: Magnetic resonance imaging (MRI) scans (L1-S1) from 50 right-convex thoracic (left-convex lumbar) AIS patients were analyzed. At each intervertebral level, VR, lumbar plexus depth (LPD), and vascular structure depth (VSD) were evaluated. Paired t test analyses were used to describe anatomic differences between the concave and convex aspect of our patients' curves. Correlation analysis was used to investigate relationships with soft tissue modifications and VR. Results: Fifty AIS patients (17M, 33F) with mean thoracic Cobb of 50.6 degrees +/- 17.0 degrees and mean lumbar Cobb of 41.9 degrees +/- 13.0 degrees were included. Mean VR at each level was L1-2 = -6.6 degrees , L2-3 = -7.7 degrees , L3-4 = -6.5 degrees , L4-5 = -4.7 degrees , L5-S1 = -2.6 degrees (negative value denotes clockwise rotation). We found significant differences (P < .05) between concave convex (right-left) LPD at each level (L1-2 = 3.7 mm, L2-3 = 5.1 mm, L3-4 = 4.2 mm, L4-5 = 2.2 mm, L5-S1 = 2.2 mm). Vascular structure depth was significantly different at L1-L2 (3.2 mm) and L5-S1 (3 mm). Significant correlation was found between increasing VR and concave-convex LPD difference (r = 0.68, P < .001). Conclusions: This study demonstrates that displacement of the lumbar plexus is tied to the magnitude of VR in patients with AIS. When approaching the lumbar spine, this displacement widens the safe surgical corridor on the convex side and narrows the corridor on the concave side. Level of Evidence: IV. Clinical Relevance: Preoperative review of MRI scans should occur to assess the patient's safe surgical corridor for lateral lumbar interbody fusion (LLIF). Adult spinal deformity surgeons who approach a degenerated spine in patients with progressive AIS in adulthood must carefully plan for patient positioning, neurovascular anatomy, and realignment objectives prior to the day of surgical intervention. PMID- 30280078 TI - Etiology and Management of Spinal Deformity in Patients With Parkinson's Disease. AB - Patients with Parkinson's disease (PD) commonly develop severe spinal deformity, including scoliosis, antecollis, camptocormia, and Pisa syndrome. The etiology of PD-associated spinal deformity is not completely understood and in most cases is likely due to multiple interrelated factors, including central dystonia and focal myopathy. Once spinal deformity has occurred, surgery is often the only modality that can correct the condition, although control of the movement disorder through medication and deep brain stimulation may slow progression. Advances in spinal instrumentation and deformity correction techniques have improved the outcomes of PD spinal deformity patients, though complications and revision surgery rates remain high. Surgical intervention is reserved for individuals who are physiologically healthy and whose condition is refractory to nonoperative management and follows similar treatment principles as other causes of neuromuscular scoliosis/kyphosis. Spinal deformity patients with PD are optimally treated by spinal deformity surgeons who are familiar with the unique needs of PD patients, with vigilant preoperative and postoperative treatment of their movement disorder and bone density. PMID- 30280079 TI - Spontaneous Epidural Hematoma of Cervical Spine. AB - Spontaneous cervical epidural hematoma is an uncommon cause of acute spinal cord compression. This is a rare idiopathic condition that leads to acute onset of neurologic deficits, which if not recognized early can have catastrophic consequences. Acute cervical epidural hematoma is definitely a condition of neurologic emergency. Although it is a rare condition, it must be considered in nontraumatic patients with sudden onset of neurologic deficits. Patients with spontaneous spinal epidural hematoma typically present with acute onset of severe back pain, and they rapidly develop signs of compression of the spinal cord or cauda equina. Here, we present a case of a 31-year-old man who presented with acute onset of neck pain with radicular component with progressive neurologic deficit. Emergent magnetic resonance imaging revealed cervical extradural hematoma with cord compression that was promptly evacuated. Functional recovery was achieved within 48 hours. The level of preoperative neurologic deficit and its severity, as well as operative interval, are important factors significantly affecting the postoperative outcome. PMID- 30280080 TI - Radiologic Analysis of C2 to Predict Safe Placement of Pedicle Screws. AB - Background: Preoperative assessment of C2 pedicle morphology is critical to safe pedicle screw placement. To avoid iatrogenic injury, complex digital templating software has been introduced; however, this technology may not be available in many centers. We report a technique for preoperative assessment of C2 pedicle screw placement safety based upon 2-dimensional sagittal computed tomography (CT) scan images and verify its utility in clinical practice. Methods: A total of 46 consecutive patients underwent cervical spine CT scans between 2005 and 2011. The C2 pedicle morphology was assessed on sagittal CT imaging by 5 independent reviewers to determine the feasibility and risk associated with pedicle screw placement. Thirty consecutive patients underwent C2 pedicle screw placement and were followed clinically for a minimum of 2 years. The ability to place a screw was noted, and accuracy of screw placement was assessed postoperatively by CT scan. Results: The CT scan analysis demonstrated that 11% (5/46) of patients had sufficient pedicle size bilaterally to allow safe placement of long pedicle screws with a low risk of vertebral artery injury, whereas 15% (7/46) were considered a high risk bilaterally. Screw placement was deemed low risk in 28%, moderate risk in 38%, and high risk in 34%. Excellent intraobserver reliability and good interobserver reliability was observed. Clinically, 18 of 20 (90%) low risk and 21 of 24 (88%) moderate-risk pedicle screws were placed safely versus 5 of 16 (31%) high-risk pedicle screws (P < .001). Conclusions: Using the described technique for evaluating the C2 pedicle via sagittal CT scan images allows for safe and reliable pedicle screw placement without relying upon complex digital templating software, which may have limited availability. Level of Evidence: II. Clinical Relevance: This study aids in the surgical decision-making behind the placement of C2 pedicle screws using CT scans without reliance upon complex digital templating software. PMID- 30280081 TI - Physician-Specific Variability in Spine Fusion Patients. AB - Background: It is often assumed that each surgeon's patient population is similar to that of his or her peers. Differences in patient characteristics naturally may lead to diverse outcomes. To date, the variability of individual surgeons' patient populations has not been adequately characterized. The purpose of this study is to describe the variation in physician-specific patient characteristics among surgeons performing spine fusion surgery at a large, urban academic medical center. Methods: We analyzed administrative data from a single institution for spine fusion surgery from 2009 to 2013. There were 6585 primary and 362 revision cases of spine fusion performed within this time period. Variability between surgeons and their respective patient populations was compared using descriptive statistics. Results: The mean annual percentage of primary fusion patients with diabetes mellitus ranged from 0 to 16.17% (mean +/- SD, 7.79% +/- 3.96%) but constituted anywhere from 0 to 41.58% (mean +/- SD, 8.15% +/- 12.09%) of revision fusions. The mean annual percentage of primary fusion patients who were obese ranged from 0 to 9% (mean +/- SD, 2.95% +/- 2.7%), and 0 to 25% in revision cases (mean +/- SD, 3.43% +/- 6.43%). The annual mean percentage of patients with American Society of Anesthesiologists (ASA) scores greater than 3 ranged from 8.8% to 44.43% (mean +/- SD, 20.42% +/- 8.85%) in primary fusions and 0 to 100% (mean +/- SD, 32.79% +/- 23.47%) in revision fusions. Conclusion: There was a large amount of variability among surgeons' patient populations when looking at characteristics such as obesity, diabetes, and ASA scores >3. These factors have been shown to impact patient outcomes. The variability in the patient populations of individual surgeons' practices even within the same medical center must be taken into account when evaluating physician specific outcomes and quality of care. PMID- 30280082 TI - Enchondroma Protuberans of the Transverse Process of D8 Vertebra Extending to the 7th and 8th Ribs: A Rare Case Report. AB - Background: Enchondroma protuberans (EP) is rare, benign cartilaginous bone tumor arising from the intramedullary cavity of long bones and usually protrudes beyond the cortex with an exophytic growth pattern resembling osteochondroma. This study reports on a rare case of EP arising from the transverse process of the D8 vertebra and extending to the adjacent 7th and 8th ribs and the paraspinal tissues. Methods: A 45-year-old female patient came in with complaints of upper back pain radiating up to the left costal margin for the past 6 months. There were no parasthesias, and there was no history of any sensory or motor symptoms. On physical examination there was midline and left paraspinal tenderness over the D6 to D8 region. Anteroposterior and lateral X-ray images revealed a well-defined oval ossific mass lesion over the lateral aspect of the D8 vertebra, extending to the 7th and 8th ribs on the left side, and multiple bridging osteophytes were noted. Computed tomography scan showed an ossific mass lesion arising from the D8 transverse process with extension to the adjacent 7th and 8th ribs; its margins were well defined, with no periosteal reaction. Magnetic resonance imaging showed a well-defined expansile mass lesion arising from the transverse process of the D8 vertebra matrix; it was was isointense with adjacent marrow and had no evidence of calcifications or vascular flow voids and no encroachment into the spinal canal. Results: Complete resection of the mass lesion with the adjacent part of the 7th and 8th ribs and with intramedullary curettage was performed and sent for histopathologic examination. Histopathology showed bony trabeculae with normal mucosal elements, and a mild hypercellularity with binucleation. Chondrocytes in the myxoid matrix located in round lacunae were compatible with enchondroma, with no evidence of atypia. The postoperative period was uneventful, and after 12 months there were no signs of recurrence noted in computed tomography scan. Conclusions: EP is a rare presentation in the dorsal spine; it should be considered in the differential diagnosis of osteochondroma, enchondroma, chondrosarcoma, and periosteal chondroid tumors. PMID- 30280083 TI - Elastomeric Lumbar Total Disc Replacement: Clinical and Radiological Results With Minimum 84 Months Follow-Up. AB - Background: Total lumbar disc replacement (TDR) devices have been designed to maintain motion, but both biomechanical and clinical data have indicated that a more controlled motion and additional load absorption in TDR would be beneficial. This work analyzed long-term results of an elastomeric disc (Physio-L) for degenerative lumbar conditions. Material and Methods: This was a prospective, noncomparative, single-center clinical and radiological study. A total of 15 patients with predominant low back pain due degenerative disc disease received anterior total disc replacement with a Physio-L disc. Clinical outcomes were assessed both with a visual analog scale for pain and Oswestry Disability Index questionnaires. Radiological outcomes included implant failure, range of motion (ROM), facet degeneration, and adjacent level disease. Complication and reoperation rates were also recorded. The cases were assessed with a minimum follow-up of 84 months. Results: A total of 15 patients were enrolled (20 TDRs) 10 single-level cases (L5S1) and 5 two-level cases (L4L5/L5S1). After 84 months, clinical outcomes scores still demonstrated significant improvement compared with baseline (P < .001). Mean visual analog scale scores dropped from 7.1 to 2.9, and the Oswestry Disability Index improved from 50 to 16. No disc has experienced migration or breakage. The average range of motion value went from a baseline of 12.0 degrees to 13.3 degrees at 12 months, and at the final follow-up it decreased to 9.9 degrees . Regarding the double-level cases, 3 of 5 (60%) had adverse events; just 1 single-level (10%) had adverse events. At final follow-up, radiological signs of facet degeneration were present in 7 of 15 patients (47%) but with only 1 of 15 (6.7%) symptomatic. Two patients (13%) required surgery at the adjacent level. At the 84-month follow-up, 16 of 18 prostheses (89%) were still active (2 revised to fusion and 2 were lost to follow-up). Conclusion: The long-term follow-up data shows satisfactory clinical results for the use of Physio-L elastomeric TDR in the treatment of degenerative disc disease. Studies with bigger cohorts are needed to replicate results and add new information regarding other details. PMID- 30280084 TI - A Prospective Analysis of the Supine and Sitting Straight-Leg Raise Test and Its Performance in Litigation Patients. AB - Background: The supine straight-leg raise (SLR) test has the potential to be exploited by malingering patients. The sitting SLR is believed to be less recognizable, therefore decreasing the chance of fabrication. The authors aim to compare the supine and sitting SLR test in patients with radiculopathy. Methods: A total of 107 patients with radiculopathy were included in this study. Two groups were created: patients with workman's compensation (Group 1) and a control group of patients without litigation claims (Group 2). Results: Mean age was 47.3 +/- 1.3 years with a 51% female population. Correlation analysis demonstrated association between mean angles in both positions, r = 0.248 with significance P = .01. There was equivalence in the mean angles in sitting position of 37 +/- 3 degrees compared to 35 +/- 2 degrees in supine position (P = .549). There was no significant difference in the mean angle at which the test became positive in the litigation group in the sitting or supine position compared to the nonlitigation group, P = .616 and P = .49 respectively. Conclusion: This study demonstrated that the SLR test is equivalent in the sitting and supine position. Therefore, patients with a positive test should have similar angles in both positions, decreasing the chance of falsifying the examination. Level of Evidence: Prospective analysis. Clinical Relevance: Clinical practice. PMID- 30280085 TI - Spinal Stenosis in the Absence of Spondylolisthesis: Can Interlaminar Stabilization at Single and Multi-levels Provide Sustainable Relief? AB - Background: In the absence of spondylolisthesis, fusion procedures are generally not recommended. However, decompression alone often does not provide long-term clinical success of intractable leg and back pain. Decompression with interlaminar stabilization (ILS) offers a new option within the clinical continuum of care by providing a nonfusion surgical alternative. The objective of this study is to examine the sustainability of decompression with ILS and to understand the clinical success at either 1 or 2 levels as a surgical treatment for nonspondylolisthesis patients with spinal stenosis. Methods: Under an FDA regulated investigational device exemption (IDE) study, a total of 322 patients were enrolled in the prospective, randomized trial. This investigation focuses only on the subset of patients (116 total) from this overall cohort who were treated with decompression plus ILS at 1 or 2 levels and who did not present with spondylolisthesis preoperatively. The patients were assessed before and after surgery up to 60 months. Results: At 60-month follow up, there was no statistically significant difference in ODI >= 15 point improvement between patient populations (81.6% of 1 level, 90.3% of 2 level). At 60 months, 83.1% of 1 level and 86.3% of 2 level patients did not require a secondary surgical procedure. At 60 months, 94.7% of 1 level and 100% of 2 level reported >=20 mm improvement in Visual Analogue Scale leg pain. Patients reported improvement in their physical state according to Short Form-12 scores (89.3% of 1 level, 88.9% of 2 level). Patient satisfaction at 60 months was 97.4% for 1 level and 93.3% for 2 level. Conclusions: The therapeutic sustainability for the treatment of spinal stenosis without spondylolisthesis with ILS at 1 or 2 levels in the lumbar region has been shown to be safe and efficacious for patients who have failed conservative treatment. Clinical Relevance: Decompression with ILS offers a nonterminal surgical option for the treatment of the symptomology of spinal stenosis, a progressive degenerative condition, that potentially can provide longer durability and stability than decompression alone. PMID- 30280086 TI - Transforaminal Lumbar Interbody Fusion With Local Bone Graft Alone for Single Level Isthmic Spondylolisthesis. AB - Background: A retrospective study of patients treated by transforaminal lumbar interbody fusion (TLIF) with local bone graft alone for single-level isthmic spondylolisthesis (IS) between April 2009 and July 2014 in a single facility. Methods: Demographic and operative data, complications, preoperative and postoperative clinical records, and radiographs were revised. The Visual Analogue Scale (VAS) and Denis Work Scale were used for clinical and functional assessment. Modified Lee et al. classification was used for assessment of union. Results: Twenty-three patients with mean age of 45.04 +/- 7.19 years had single level TLIF with local bone graft alone for symptomatic IS with mean follow-up period of 28.39 +/- 4.01 months and mean operative time of 170.09 +/- 11.22 minutes. The VAS and Denis Work Scale improved from 8.48 +/- 0.58 and 4.67 +/- 0.47 preoperative to 2.91 +/- 1.25 and 1.33 +/- 0.58 at the latest follow up, respectively. Anterior vertebral translation improved from 27.22 +/- 9.54% preoperatively to 8.38 +/- 3.63% postoperatively and 10.39 +/- 3.49 at the latest follow up. Disc space height was 9.67 +/- 5.55% preoperatively, 21.60 +/- 4.11% postoperative, and 16.24 +/- 4.02% at the latest follow up. Lumbar lordosis improved from 29.39 +/- 10.33 degrees to 45.13 +/- 6.84 degrees postoperatively and 39.96 +/- 7.52 degrees at the latest follow up. Eighteen patients had definitive union, 4 patients with possible union, 1 patient with possible pseudoarthrosis. Conclusions: Transforaminal lumbar interbody fusion with local bone graft alone is an appropriate option for single-level IS, yet we do not recommend it for higher grades of slippage with anterior vertebral translation more than 25%. PMID- 30280087 TI - Transforaminal Lumbar Interbody Fusion With Viable Allograft: 75 Consecutive Cases at 12-Month Follow-up. AB - Background: When conservative treatments fail to alleviate the discomfort of abnormal motion, spinal fusion has been shown to provide symptomatic treatment for spinal instability, stenosis, spondylolisthesis, and symptomatic degenerative disc disease. The trend and rates of fusion over the past few years have been dramatic in the United States. Accompanying that higher incidence has been the shifting from traditional open surgery to minimally invasive techniques to reduce scar tissue formation, extent of muscle stripping, and muscle retraction which all have been shown to adversely affect outcomes. Other reasons supporting the widespread transition to minimally invasive surgical (MIS) techniques include decreased postoperative pain, decreased intraoperative blood loss, shorter postoperative hospital stay, faster return to normal activity, and reduced reoperation rates. Spinal fusion procedures rely on a bony fusion substrate in addition to fixation hardware. While available grafting options include autogenous, allogeneic, and synthetic materials, recent interest in viable allograft material with living cells has drawn attention and attraction for incorporating a biologic basis for regenerative consideration. A recent viable allograft, complete with cellular and designated bone carrier (VIA Graft, Vivex Biomedical, Marietta, Georgia) has been developed. This study represents a retrospective review of a single-practice, single-surgeon evaluation of the product in 75 consecutive patients for fusion by computed tomography (CT) and radiographic evaluation at 12 months in conjunction with a MIS approach. Viable allograft was used to fill the peri-implant space, and central implant lumen was filled with a cancellous bone sponge soaked in perivertebral bone marrow. Posterolateral supplementation was attained with beta-tricalcium phosphate as a bulking agent. Methods: A retrospective review identified patients treated for both primary and revision surgery who received VIA Graft cellular bone matrix material in minimally invasive interbody fusion (MIS-TLIF) with a minimum of 12 month follow up. The patient diagnoses included radiculopathy in all instances and varied collateral indications such as foraminal collapse, recurrent disc herniation, and spondylolisthesis to which pain and morbidity had been unresolved by conservative treatment. Adverse events including infection, revisions, and evidence of immune response were evaluated and patient comorbidities defined for the entire population of patients. Patient fusion status was assessed using thin slice CT by 2 independent radiologists separate from the surgeon. There were 75 consecutive adult patients with degenerative conditions of the lumbar spine who underwent MIS-TLIF surgery of which 40 (53%) were male and 35 (47%) were female. Mean age, height, and weight were 58 years, 170.18 cm (67 in), and 88.45 kg (195 lbs), respectively. The mean body mass index was 30. There were 16 patients (21%) who smoked and 12 (16%) with a history of diabetes. Independent blinded review of fusion was obtained by a board certified musculoskeletal radiologist and an experienced board certified orthopaedic surgeon to assess patient fusion status. Spinal segments were deemed fused if 12-month CT scans demonstrated evidence of bridging bone at the fusion site without observed motion on flexion-extension radiographs. Findings such as osteolysis around the implant or pedicle screws, extensive endplate cystic changes, or linear defects parallel to the endplates through intradiscal new bone formation were interpreted as signs of pseudarthrosis. Interobserver and intraobserver error and kappa assessments were analyzed to assure agreement in the CT outcomes assessment where interpretation of kappa were as follows: <0.00 = poor agreement, 0.00-0.20 = slight agreement, 0.21-0.40 = fair agreement, 0.41-0.60 = moderate agreement, 0.61-0.80 = substantial agreement, and 0.81-1.00 = almost perfect agreement. Differences were resolved by consensus amongst the observers. Results: In total, 96% of the 75 patients with a total of 85 levels (96.5% of levels treated) achieved a fusion at 12 months. There were no perioperative or latent complications and no transfusions in all 75 patients. Conclusions: In this population, 96% of the patients treated achieved the surgical objective in 96.5% of the levels treated. Level of Evidence: IV. Clinical Relevance: The high rate of fusion, the lack of secondary morbidity with autologous bone harvest, and the clinical success account for the benefits of viable allograft matrix for MIS-TLIF use. PMID- 30280088 TI - Anterior Fixation of Floating Facet Fractures in the Cervical Spine: A Prospective Case Series and Biomechanical Analysis. AB - Background: Unilateral fractures involving complete separation of the lateral mass from the vertebra and lamina (floating lateral mass fractures) are a unique subset of cervical spine fractures. These injuries are at significant risk for displacement without operative fixation. Posterior fixation has proven to facilitate adequate fusion. However, there are few data supporting the clinical success of single-level anterior fixation. Methods: Biomechanical evaluation of floating lateral mass fractures and a consecutive case series of patients with rotationally unstable floating lateral mass fractures treated with anterior fixation using an integrated cage-screw device with anterior plating (ICSD) was performed. The study comprised 7 fresh human cadaver cervical spines (C2-C7), and 11 patients with floating lateral mass fractures. Segmental flexibility testing evaluating axial rotation, flexion/extension, and lateral bending was performed in a cadaveric model after 2 types of single-level anterior fixation and 1 type of 2-level posterior fixation. Eleven patients with a floating lateral mass fracture of the cervical spine underwent anterior fixation with an ICSD. Radiographs and clinical outcomes were retrospectively reviewed. Results: Compared with the intact condition, posterior instrumentation significantly (P < .05) reduced range of motion (ROM) in all 3 planes; anterior fixation with cervical plate and interbody spacer significantly reduced ROM in lateral bending only; and the ICSD significantly reduced ROM in flexion/extension and lateral bending. In the clinical arm, there were no long-term complications, subsidence >2 mm, failure of fixation, reoperation, pseudoarthrosis, or listhesis at final follow-up. Conclusions: The addition of 2 screws placed through a cervical cage can improve anterior fixation in a human cadaveric model of floating lateral mass fractures. Early clinical results demonstrate a low complication rate and a high rate of healing with single-level anterior fixation using this technique. PMID- 30280089 TI - Corrigendum: Circular RNAs in Cancer - Lessons Learned From microRNAs. AB - [This corrects the article DOI: 10.3389/fonc.2018.00179.]. PMID- 30280092 TI - The Virulence Effect of CpxRA in Citrobacter rodentium Is Independent of the Auxiliary Proteins NlpE and CpxP. AB - Citrobacter rodentium is a murine pathogen used to model the intestinal infection caused by Enteropathogenic and Enterohemorrhagic Escherichia coli (EPEC and EHEC), two diarrheal pathogens responsible for morbidity and mortality in developing and developed countries, respectively. During infection, these bacteria must sense and adapt to the gut environment of the host. In order to adapt to changing environmental cues and modulate expression of specific genes, bacteria can use two-component signal transduction systems (TCS). We have shown that the deletion of the Cpx TCS in C. rodentium leads to a marked attenuation in virulence in C3H/HeJ mice. In E. coli, the Cpx TCS is reportedly activated in response to signals from the outer-membrane lipoprotein NlpE. We therefore investigated the role of NlpE in C. rodentium virulence. We also assessed the role of the reported negative regulator of CpxRA, CpxP. We found that as opposed to the DeltacpxRA strain, neither the DeltanlpE, DeltacpxP nor the DeltanlpEDeltacpxP strains were significantly attenuated, and had similar in vivo localization to wild-type C. rodentium. The in vitro adherence of the Cpx auxiliary protein mutants, DeltanlpE, DeltacpxP, DeltanlpEDeltacpxP, was comparable to wild-type C. rodentium, whereas the DeltacpxRA strain showed significantly decreased adherence. To further elucidate the mechanisms behind the contrasting virulence phenotypes, we performed microarrays in order to define the regulon of the Cpx TCS. We detected 393 genes differentially regulated in the DeltacpxRA strain. The gene expression profile of the DeltanlpE strain is strikingly different than the profile of DeltacpxRA with regards to the genes activated by CpxRA. Further, there is no clear inverse correlation in the expression pattern of the DeltacpxP strain in comparison to DeltacpxRA. Taken together, these data suggest that in these conditions, CpxRA activates gene expression in a largely NlpE- and CpxP-independent manner. Compared to wildtype, 161 genes were downregulated in the DeltacpxRA strain, while being upregulated or unchanged in the Cpx auxiliary protein deletion strains. This group of genes, which we hypothesize may contribute to the loss of virulence of DeltacpxRA, includes T6SS components, ompF, the regulator for colanic acid synthesis, and several genes involved in maltose metabolism. PMID- 30280090 TI - The Role of Immunohistochemical Analysis as a Tool for the Diagnosis, Prognostic Evaluation and Treatment of Prostate Cancer: A Systematic Review of the Literature. AB - Background: Prostate cancer (PCa) is a heterogeneous disease that lends itself toward numerous therapeutic options depending on its risk stratification. One of the greatest challenges in PCa urologic practice is to select patients who should be referred for biopsy and, for those patients who are diagnosed with cancer, to differentiate between patients with indolent disease from those with an unfavorable prognosis and, to determine ideal patient management and avoid unnecessary interventions. Accordingly, there is a growing body of literature reporting immunohistochemical studies with the objective of determining a prostate cancer prognosis. Among the most frequent biomarkers studied are Ki-67, p53, PTEN, MYC, and ERG. Based on these findings, we systematically reviewed articles that assessed the role of these main prognostic markers in prostate cancer. Methods: Consistent with PRISMA guidelines, we performed a systematic literature search throughout the Web of Science and PubMed Medline databases. We considered all types of studies evaluating the role of Ki-67, p53, PTEN, MYC, and ERG immunohistochemical analysis in prostate cancer until July 2017. Results: We identified 361 articles, 44 of which were summarized in this review. Diagnostically, no single immunohistochemical marker was able to define a tumor as benign or malignant. Prognostically, Ki-67, p53, and MYC were related to the tumor grade given by Gleason score and to the tumor stage (higher levels related to higher tumor grade). Furthermore, Ki-67 was also related to higher PSA levels, shorter disease-free intervals and shorter tumor-specific survival; the latter was also related to p53. The loss of PTEN protein expression showed a higher association with biochemical recurrence and with a worse prognosis, beyond that predicted by the Gleason score and tumor stage. ERG staining also showed a strong association with biochemical recurrence. Conclusion: There are several studies relating immunohistochemical markers with clinical-laboratorial outcomes in prostate cancer, the most frequent being Ki-67, p53, ERG, PTEN, and MYC. However, none of these markers have been validated by literary consensus to be routinely applied in medical practice. PMID- 30280093 TI - Yersinia pseudotuberculosis BarA-UvrY Two-Component Regulatory System Represses Biofilms via CsrB. AB - The formation of biofilms by Yersinia pseudotuberculosis (Yptb) and Y. pestis requires the hmsHFRS genes, which direct production of a polysaccharide extracellular matrix (Hms-ECM). Despite possessing identical hmsHFRS sequences, Yptb produces much less Hms-ECM than Y. pestis. The regulatory influences that control Yptb Hms-ECM production and biofilm formation are not fully understood. In this study, negative regulators of biofilm production in Yptb were identified. Inactivation of the BarA/UvrY two-component system or the CsrB regulatory RNA increased binding of Congo Red dye, which correlates with extracellular polysaccharide production. These mutants also produced biofilms that were substantially more cohesive than the wild type strain. Disruption of uvrY was not sufficient for Yptb to cause proventricular blockage during infection of Xenopsylla cheopis fleas. However, this strain was less acutely toxic toward fleas than wild type Yptb. Flow cytometry measurements of lectin binding indicated that Yptb BarA/UvrY/CsrB mutants may produce higher levels of other carbohydrates in addition to poly-GlcNAc Hms-ECM. In an effort to characterize the relevant downstream targets of the BarA/UvrY system, we conducted a proteomic analysis to identify proteins with lower abundance in the csrB::Tn5 mutant strain. Urease subunit proteins were less abundant and urease enzymatic activity was lower, which likely reduced toxicity toward fleas. Loss of CsrB impacted expression of several potential regulatory proteins that may influence biofilms, including the RcsB regulator. Overexpression of CsrB did not alter the Congo-red binding phenotype of an rcsB::Tn5 mutant, suggesting that the effect of CsrB on biofilms may require RcsB. These results underscore the regulatory and compositional differences between Yptb and Y. pestis biofilms. By activating CsrB expression, the Yptb BarA/UvrY two-component system has pleiotropic effects that impact biofilm production and stability. PMID- 30280091 TI - The Redox-Sensing Regulator Rex Contributes to the Virulence and Oxidative Stress Response of Streptococcus suis Serotype 2. AB - Streptococcus suis serotype 2 (SS2) is an important zoonotic pathogen responsible for septicemia and meningitis. The redox-sensing regulator Rex has been reported to play critical roles in the metabolism regulation, oxidative stress response, and virulence of various pathogens. In this study, we identified and characterized a Rex ortholog in the SS2 virulent strain SS2-1 that is involved in bacterial pathogenicity and stress environment susceptibility. Our data show that the Rex-knockout mutant strain Deltarex exhibited impaired growth in medium with hydrogen peroxide or a low pH compared with the wildtype strain SS2-1 and the complementary strain CDeltarex. In addition, Deltarex showed a decreased level of survival in whole blood and in RAW264.7 macrophages. Further analyses revealed that Rex deficiency significantly attenuated bacterial virulence in an animal model. A comparative proteome analysis found that the expression levels of several proteins involved in virulence and oxidative stress were significantly different in Deltarex compared with SS2-1. Electrophoretic mobility shift assays revealed that recombinant Rex specifically bound to the promoters of target genes in a manner that was modulated by NADH and NAD+. Taken together, our data suggest that Rex plays critical roles in the virulence and oxidative stress response of SS2. PMID- 30280094 TI - Bovine Epithelial in vitro Infection Models for Mycoplasma bovis. AB - Mycoplasma bovis causes bovine mycoplasmosis. The major clinical manifestations are pneumonia and mastitis. Recently an increase in the severity of mastitis cases was reported in Switzerland. At the molecular level, there is limited understanding of the mechanisms of pathogenicity of M. bovis. Host-pathogen interactions were primarily studied using primary bovine blood cells. Therefore, little is known about the impact of M. bovis on other cell types present in infected tissues. Clear in vitro phenotypes linked to the virulence of M. bovis strains or tissue predilection of specific M. bovis strains have not yet been described. We adapted bovine in vitro systems to investigate infection of epithelial cells with M. bovis using a cell line (MDBK: Madin-Darby bovine kidney cells) and two primary cells (PECT: bovine embryonic turbinate cells and bMec: bovine mammary gland epithelial cells). Two strains isolated before and after the emergence of severe mastitis cases were selected. Strain JF4278 isolated from a cow with mastitis and pneumonia in 2008 and strain L22/93 isolated in 1993 were used to assess the virulence of M. bovis genotypes toward epithelial cells with particular emphasis on mammary gland cells. Our findings indicate that M. bovis is able to adhere to and invade different epithelial cell types. Higher titers of JF4278 than L22/93 were observed in co-cultures with cells. The differences in titers reached between the two strains was more prominent for bMec cells than for MDBK and PECT cells. Moreover, M. bovis strain L22/93 induced apoptosis in MDBK cells and cytotoxicity in PECT cells but not in bMec cells. Dose-dependent variations in proliferation of primary epithelial cells were observed after M. bovis infection. Nevertheless, an indisputable phenotype that could be related to the increased virulence toward mammary gland cells is not obvious. PMID- 30280096 TI - Ubiquitin Receptor RPN13 Mediates the Inhibitory Interaction of Diphenyldihaloketones CLEFMA and EF24 With the 26S Proteasome. AB - The proteasome is a validated target in drug discovery for diseases associated with unusual proteasomal activity. Here we report that two diphenyldihaloketones, CLEFMA and EF24, inhibit the peptidase activity of the 26S proteasome. The objective of this study was to investigate interaction of these compounds with the proteasome and identify a putative target within the protein components of the 26S proteasome. We employed standard fluorogenic peptide-based proteasome activity assay for trypsin-like, chymotrypsin-like, and caspase-like activities of human purified 26S proteasome in cell-free conditions. GFPu-1 and HUVEC cells were used as proteasome reporter cells. Direct binding studies used purified 19S, 20S, 26S, and recombinant RPN13-Pru for interaction with biotinylated analogs of CLEFMA and EF24. The reaction mixtures were subjected to horizontal gel electrophoresis, streptavidin-blotting, pull-down assays, and immunoblotting. The identity of the interacting protein was determined by 2D gel electrophoresis and LC-MS/MS. Drug affinity responsive target stability technique was utilized to examine if CLEFMA binding confers protection to RPN13 against thermolysin catalyzed proteolysis. We found that trypsin-and chymotrypsin-like activities of the 26S proteasome were reduced significantly by both compounds. The compounds also reduced the proteolytic activity in GFPu-1 and HUVEC cells, resulting in accumulation of ubiquitinated proteins without affecting the autophagy process. From direct binding assays a 43 kDa protein in the 26S proteasome was found to be the interacting partner. This protein was identified by tandem mass spectroscopy as regulatory particle subunit 13 (RPN13), a ubiquitin receptor in the 19S regulatory particle. Furthermore, binding of CLEFMA to RPN13 did not protect latter from thermolysin-mediated proteolysis. Together, this study showed diphenyldihaloketones as potential proteasome inhibitors for treatment of diseases with perturbed proteasome function. The results also unraveled RPN13 as a unique target of CLEFMA and EF24. As a result, these compounds inhibit both trypsin-like and chymotrypsin-like proteasome activities. PMID- 30280098 TI - Abundantly Present miRNAs in Milk-Derived Extracellular Vesicles Are Conserved Between Mammals. AB - Mammalian milk is not only a source of nutrition for the newborn, but also contains various components that regulate further development. For instance, milk is an abundant source of microRNAs (miRNAs), which are evolutionary conserved small non-coding RNAs that are involved in post-transcriptional regulation of target mRNA. MiRNAs present in milk can occur in extracellular vesicles (EVs), which are nanosized membrane vesicles released by many cell types as a means of intercellular communication. The membrane of EVs protects enclosed miRNAs from degradation and harbors molecules that allow specific targeting to recipient cells. Although several studies have investigated the miRNA content in milk EVs from individual species, little is known about the evolutionary conserved nature of EV-associated miRNAs among different species. In this study, we profiled the miRNA content of purified EVs from human and porcine milk. These data were compared to published studies on EVs from human, cow, porcine, and panda milk to assess the overlap in the top 20 most abundant miRNAs. Interestingly, several abundant miRNAs were shared between species (e.g., let-7 family members let-7a, let-7b, let-7f, and miR-148a). Moreover, these miRNAs have been implicated in immune-related functions and regulation of cell growth and signal transduction. The conservation of these miRNA among species, not only in their sequence homology, but also in their incorporation in milk EVs of several species, suggests that they are evolutionarily selected to regulate cell function in the newborn. PMID- 30280097 TI - Analysis of the Transcriptome in Aspergillus tamarii During Enzymatic Degradation of Sugarcane Bagasse. AB - The production of bioethanol from non-food agricultural residues represents an alternative energy source to fossil fuels for incorporation into the world's economy. Within the context of bioconversion of plant biomass into renewable energy using improved enzymatic cocktails, Illumina RNA-seq transcriptome profiling was conducted on a strain of Aspergillus tamarii, efficient in biomass polysaccharide degradation, in order to identify genes encoding proteins involved in plant biomass saccharification. Enzyme production and gene expression was compared following growth in liquid and semi-solid culture with steam-exploded sugarcane bagasse (SB) (1% w/v) and glucose (1% w/v) employed as contrasting sole carbon sources. Enzyme production following growth in liquid minimum medium supplemented with SB resulted in 0.626 and 0.711 UI.mL-1 xylanases after 24 and 48 h incubation, respectively. Transcriptome profiling revealed expression of over 7120 genes, with groups of genes modulated according to solid or semi-solid culture, as well as according to carbon source. Gene ontology analysis of genes expressed following SB hydrolysis revealed enrichment in xyloglucan metabolic process and xylan, pectin and glucan catabolic process, indicating up-regulation of genes involved in xylanase secretion. According to carbohydrate-active enzyme (CAZy) classification, 209 CAZyme-encoding genes were identified with significant differential expression on liquid or semi-solid SB, in comparison to equivalent growth on glucose as carbon source. Up-regulated CAZyme-encoding genes related to cellulases (CelA, CelB, CelC, CelD) and hemicellulases (XynG1, XynG2, XynF1, XylA, AxeA, arabinofuranosidase) showed up to a 10-fold log2FoldChange in expression levels. Five genes from the AA9 (GH61) family, related to lytic polysaccharide monooxygenase (LPMO), were also identified with significant expression up-regulation. The transcription factor gene XlnR, involved in induction of hemicellulases, showed up-regulation on liquid and semi-solid SB culture. Similarly, the gene ClrA, responsible for regulation of cellulases, showed increased expression on liquid SB culture. Over 150 potential transporter genes were also identified with increased expression on liquid and semi-solid SB culture. This first comprehensive analysis of the transcriptome of A. tamarii contributes to our understanding of genes and regulatory systems involved in cellulose and hemicellulose degradation in this fungus, offering potential for application in improved enzymatic cocktail development for plant biomass degradation in biorefinery applications. PMID- 30280099 TI - Outcome of the "Manchester Groin Repair" (Laparoscopic Totally Extraperitoneal Approach With Fibrin Sealant Mesh Fixation) in 434 Consecutive Inguinal Hernia Repairs. AB - Introduction: This study looks at the outcome of 352 patients that underwent the "Manchester groin repair" in the period from 2007 to 2016. The effect of laterality on chronic groin pain and the reduction of pain scores post-surgery are evaluated as well as the rate of hernia recurrence for the inguinal hernia repairs. Methods: The "Manchester groin repair" is a modification of a laparoscopic totally extra-peritoneal approach with fibrin sealant mesh fixation. Data were collected prospectively. In addition to demographic data and the European Hernia Society classification grading of each hernia, pain scores were assessed prior to surgery and at 4-6 weeks post-operatively using a ten-point visual analog pain scale. Data were collected on a bespoke database and differences between time-points analyzed by non-parametric Wilcoxon signed rank tests with Kruskal-Wallis rank sum test for three-group comparisons. Significance was at the P < 0.05 level. The study was undertaken as an institutional audit. Results: Three hundred and fifty two patients underwent TEP repair as per the "Manchester Groin Repair" modification during the period of interest with a median follow-up period of 109.5 (IQR 57.0-318.5) weeks. Of these 274 (77.8%) were for the repair of true hernias and 78 (22.2%) were for inguinal disruptions. All inguinal hernia repairs patients were evaluated (254 m, 20 f); median [interquartile range] age 50 (39-65) years. There were 75 right inguinal hernias (27.4%), 39 Left inguinal hernias (14.2%), and 160 bilateral inguinal hernias (58.4%), giving a total of 434 hernia repairs. During follow-up there were 6 recurrences (1.4%).Of the 274 patients evaluated, 145 (52.9%) had both pre and post-operative pain scores available. Median pre-operative pain score was 5 [IQR 4-7]. Median post-operative pain score was 1 [IQR 1-2]. This difference was significant (P < 0.001). Pre-operative pain scores were higher for those with a bilateral hernia (median 6 vs. 5 and 4, respectively; P = 0.005), but there was no difference in post-operative scores (P = 0.347). One patient (0.3%) presented with chronic groin pain (pain after 3 months). Conclusion: This study demonstrates that the "Manchester groin repair" provides an excellent repair with a low rate of recurrence and low incidence of chronic pain. Longer-term evaluation and larger patient series will add to the understanding of the role of this procedure in groin hernia repair. PMID- 30280101 TI - Response Gene to Complement 32 in Vascular Diseases. AB - Response gene to complement 32 (RGC32) is a protein that was identified in rat oligodendrocytes after complement activation. It is expressed in most of the organs and tissues, such as brain, placenta, heart, and the liver. Functionally, RGC32 is involved in various physiological and pathological processes, including cell proliferation, differentiation, fibrosis, metabolic disease, and cancer. Emerging evidences support the roles of RGC32 in vascular diseases. RGC32 promotes injury-induced vascular neointima formation by mediating smooth muscle cell (SMC) proliferation and migration. Moreover, RGC32 mediates endothelial cell activation and facilitates atherosclerosis development. Its involvement in macrophage phagocytosis and activation as well as T-lymphocyte cell cycle activation also suggests that RGC32 is important for the development and progression of inflammatory vascular diseases. In this mini-review, we provide an overview on the roles of RGC32 in regulating functions of SMCs, endothelial cells, and immune cells, and discuss their contributions to vascular diseases. PMID- 30280102 TI - Single telomere length analysis in Ustilago maydis, a high-resolution tool for examining fungal telomere length distribution and C-strand 5'-end processing. AB - Telomeres play important roles in genome stability and cell proliferation. Telomere lengths are heterogeneous and because just a few abnormal telomeres are sufficient to trigger significant cellular response, it is informative to have accurate assays that reveal not only average telomere lengths, but also the distribution of the longest and shortest telomeres in a given sample. Herein we report for the first time, the development of single telomere length analysis (STELA) - a PCR-based assay that amplifies multiple, individual telomeres - for Ustilago maydis, a basidiomycete fungus. Compared to the standard telomere Southern technique, STELA revealed a broader distribution of telomere size as well as the existence of relatively short telomeres in wild type cells. When applied to blm?, a mutant thought to be defective in telomere replication, STELA revealed preferential loss of long telomeres, whose maintenance may thus be especially dependent upon efficient replication. In comparison to blm?, the trt1? (telomerase null) mutant exhibited greater erosion of short telomeres, consistent with a special role for telomerase in re-lengthening extra-short telomeres. We also used STELA to characterize the 5' ends of telomere C-strand, and found that in U. maydis, they terminate preferentially at selected nucleotide positions within the telomere repeat. Deleting trt1 altered the 5'-end distributions, suggesting that telomerase may directly or indirectly modulate C-strand 5' end formation. These findings illustrate the utility of STELA as well as the strengths of U. maydis as a model system for telomere research. PMID- 30280100 TI - Mapping and Ablation of Idiopathic Ventricular Fibrillation. AB - Idiopathic ventricular fibrillation (IVF) is the main cause of unexplained sudden cardiac death, particularly in young patients under the age of 35. IVF is a diagnosis of exclusion in patients who have survived a VF episode without any identifiable structural or metabolic causes despite extensive diagnostic testing. Genetic testing allows identification of a likely causative mutation in up to 27% of unexplained sudden deaths in children and young adults. In the majority of cases, VF is triggered by PVCs that originate from the Purkinje network. Ablation of VF triggers in this setting is associated with high rates of acute success and long-term freedom from VF recurrence. Recent studies demonstrate that a significant subset of IVF defined by negative comprehensive investigations, demonstrate in fact subclinical structural alterations. These localized myocardial alterations are identified by high density electrogram mapping, are of small size and are mainly located in the epicardium. As reentrant VF drivers are often colocated with regions of abnormal electrograms, this localized substrate can be shown to be mechanistically linked with VF. Such areas may represent an important target for ablation. PMID- 30280095 TI - Viral Sepsis in Children. AB - Sepsis in children is typically presumed to be bacterial in origin until proven otherwise, but frequently bacterial cultures ultimately return negative. Although viruses may be important causative agents of culture-negative sepsis worldwide, the incidence, disease burden and mortality of viral-induced sepsis is poorly elucidated. Consideration of viral sepsis is critical as its recognition carries implications on appropriate use of antibacterial agents, infection control measures, and, in some cases, specific, time-sensitive antiviral therapies. This review outlines our current understanding of viral sepsis in children and addresses its epidemiology and pathophysiology, including pathogen-host interaction during active infection. Clinical manifestation, diagnostic testing, and management options unique to viral infections will be outlined. PMID- 30280103 TI - Temporal analysis of the autophagic and apoptotic phenotypes in Leishmania parasites. AB - The leishmaniases are worldwide neglected tropical diseases caused by parasitic protozoa of the Leishmania genus. Different stimuli induce Leishmania cell death, but the proteins involved remain poorly understood. Furthermore, confusion often appears between cell death and the cell survival process autophagy, whose phenotype is not clearly defined. In this article, we present a comprehensive and temporal analysis of the cellular events occurring during miltefosine-induced cell death and autophagy in L. major. We also provide a list of features in order to clearly identify apoptotic cells, autophagic cells and to distinguish both processes. Furthermore, we demonstrate that autophagy is followed by apoptosis in the absence of nutrients. Finally, we show that cells treated with the generic kinase inhibitor staurosporine express apoptotic as well as autophagic markers and therefore cannot be used as an apoptosis inducer in Leishmania. These descriptions lead to a better recognition and understanding of apoptosis and autophagy, enabling their targeting in the development of new anti-leishmanial drugs. These researches also make it possible to better understand these processes in general, through the study of an ancestral eukaryote. PMID- 30280104 TI - Escherichia coli hijack Caspr1 receptor to invade cerebral vascular and neuronal hosts. AB - Escherichia coli (E. coli) penetration of the blood-brain barrier (BBB) is the key step essential for the development of meningitis. In a recent paper (Nat Commun 9:2296), we identify Caspr1 as a host receptor for E. coli virulence factor IbeA to pave the way the penetration of bacteria through the BBB. Bacterial IbeA interacts with endothelial Caspr1 to trigger intracellular focal adhesion kinase activation, leading to E. coli internalization into the brain endothelial cells. Importantly, endothelial knockout of Caspr1 in mice significantly reduced E. coli crossing through the BBB. Based on the results that extracellular aa 203-355 of Caspr1 bind with IbeA, we tested the blocking effect of recombinant Caspr1(203-355) peptides in neonatal rat model of meningitis. The results showed that Caspr1(203-355) peptides effectively attenuated E. coli penetration into the brain during meningitis, indicating that Caspr1(203-355) peptides could be used to neutralize the virulent IbeA to prevent meningitis. We further found that E. coli can directly invade into hippocampal neurons causing apoptosis which required the interaction between bacterial IbeA and neuronal Caspr1. These findings demonstrate that E. coli hijack Caspr1 as a host receptor for penetration of BBB and invasion of hippocampal neurons, resulting in progression of meningitis. PMID- 30280105 TI - Toxin release mediated by the novel autolysin Cwp19 in Clostridium difficile. AB - Clostridium difficile, also known as Clostriodioides difficile, is a Gram positive, spore-forming bacterium and a leading cause of antibiotic-associated diarrhea in nosocomial environments. The key virulence factors of this pathogen are two toxins, toxin A and toxin B, released from the cells to the gut and causing colonic injury and inflammation. Although their mechanism of action is well known, the toxins A and B have no peptide signals and their secretion mechanisms involving the holin-like protein TcdE and autolysis are still under active investigation. Autolysis is primarily mediated by peptidoglycan hydrolases, an important group of enzymes that cleave covalent bonds in the cell wall peptidoglycan. Peptidoglycan hydrolases are essential for peptidoglycan remodeling but most of them also have the potential to lyse the cells under various conditions. In a recent report by Wydau-Dematteis et al. (MBio 9(3): e00648-18), we characterized a novel peptidoglycan hydrolase Cwp19 in C. difficile. Importantly, Cwp19 mediates toxins secretion in a glucose-dependent fashion suggesting a potential role in C. difficile pathogenesis. Peptidoglycan hydrolases are not very well characterized in C. difficile despite the important role of these enzymes in cell division and sporulation as shown in model organisms like Bacillus subtilis. In addition, these enzymes can be implicated in pathogenicity as exemplified by the release of pneumococcal virulence factors. PMID- 30280106 TI - Spontaneous Intramural Esophageal Rupture: An Uncommon Presentation of Eosinophilic Esophagitis Requiring Endoscopic Clipping. AB - Spontaneous intramural esophageal rupture (SIER) is a form of acute esophageal trauma defined as an injury deeper than a Mallory-Weiss tear but not extending completely through the muscular propria as in Boerhaave syndrome. SIER is a rare complication of eosinophilic esophagitis (EoE); after extensive literature review, we found 7 case reports of SIER complicating EoE. We present a case of SIER complicating EoE in a 46-year-old man with an atypical presentation requiring endoscopic clipping to achieve successful hemostasis. PMID- 30280107 TI - Osteomyelitis as a Result of Pancreaticojejunostomy Stent Migration after Whipple Procedure. AB - Pancreaticoduodenectomy, or Whipple procedure, is a high-risk surgical procedure commonly performed for tumors of the pancreatic head. The pancreatico-enteric anastomosis is an important component of this procedure. The maturation and adequate healing of this anastomotic site is critical to decrease the risk of postoperative pancreatic fistulas. The use of stents can help in the healing of this anastomotic site. We present a patient with pancreatic adenocarcinoma who underwent pancreaticoduodenectomy, and presented with progressively worsening lumbar pain 7 years later. The patient was found to have osteomyelitis as a complication from an entero-spinal fistula secondary to a migrated pediatric feeding tube that was placed at the pancreaticojejunal anastomosis. PMID- 30280108 TI - Endoscopic Doppler Probe in the Diagnosis and Management of Upper Gastrointestinal Hemorrhage. AB - Through-the-scope (TTS) endoscopic Doppler ultrasound probe technology is a tool that has garnered interest for the evaluation of variceal and non-variceal bleeding. In previous studies, this technology has been proposed as a more objective method of identifying the bleeding subsurface blood vessel in peptic ulcer hemorrhage. We describe 3 cases where the use of an endoscopic Doppler probe guided the diagnosis and management of upper gastrointestinal (GI) hemorrhage due to causes other than peptic ulcer disease. The first case describes a patient with a duodenal Dieulafoy lesion, while the other 2 cases outline patients with a gastroesophageal varix as the etiology of the bleed. PMID- 30280109 TI - Intragastric Balloon Hyperinsufflation as a Cause of Acute Obstructive Abdomen. AB - Recently, the Food and Drug Administration approved the use of the Orbera balloon for obesity treatment. However, the Food and Drug Administration later issued a warning about the possibility of 2 complications not previously reported: acute pancreatitis and balloon hyperinsufflation. This case report is intended to alert all clinicians that, although rare, cases of hyperinsufflation should be considered in patients with an intragastric balloon (IGB) and acute abdomen. IGB removal will resolve the complaints, provided there is no irreversible ischemia of the stomach walls. Care should be taken with respect to an increased risk of pulmonary aspiration at the time of balloon removal, and endotracheal intubation is highly recommended. PMID- 30280110 TI - Multiple Hepatic Abscess from Parvimonas micra: An Emerging Gastrointestinal Microbe. AB - Parvimonas micra is an obligate anaerobic bacterium and a known commensal of the human oral cavity and gastrointestinal tract. It is rarely associated with infections outside the oral cavity. Recently it has been isolated as a causative agent in a variety of systemic infections, but it has never been previously identified to cause a hepatic abscess. We report a 90-year-old woman with multiple hepatic abscesses caused by P. micra. PMID- 30280111 TI - Barium Enema for Treatment for Diverticular Bleeding. AB - Diverticula of the colon are the most common cause of lower gastrointestinal bleeding in adults. In cases of persistent loss of blood or severe acute hemorrhage, treatment is required. However, if these modern intervention techniques are inadequate, surgical resection of the colon may be required. Diverticular bleeding often concerns patients with a high surgical risk, so a less invasive treatment is preferable. A forgotten but excellent treatment, namely that of the obsolete barium contrast enema to staunch diverticular bleeding, is the focus of this case series. We describe 3 patients who were successfully treated with barium enema. PMID- 30280112 TI - The prevalence of malnutrition based on anthropometry among primary schoolchildren in Binh Dinh province, Vietnam in 2016. AB - Objective: The study was conducted to determine the prevalence of malnutrition based on anthropometry among primary schoolchildren in Binh Dinh province, Vietnam. Material and Methods: This was a school-based cross-sectional survey using random sample technique with multistage process. Variables in malnutrition were classifed as thinness, stunting, underweight, overweight, and obesity based on z-scores according to the World Health Organization (WHO) (2007). Anthropometric measurements were taken according to WHO's standard procedures. The Chi-square test was used to compare prevalences and the Chi-square test for trend was employed to assess the trend of the prevalence of malnutrition forms by age. Results: 6,514 pupils from 6 to 10 years old including 3,298 males and 3,216 females were observed. The prevalence of thinness, stunting, underweight, overweight and obesity among schoolchildren accounted for 11.19%, 6.16%, 10.79%, and 30.1%, respectively. The prevalence of underweight and that of overweight obesity of all pupils at the age of 6 were 13.1% and 32.11%, respectively, and tended to decrease to age 10 (p < 0.01). The prevalence of thin and stunted pupils had little sign of change over ages (p > 0.05). There was a statistically significant difference in the prevalence of malnutrition in three areas of Binh Dinh (p < 0.05), in which the highest prevalence of undernutrition was in mountainous area and midland, and the highest prevalence of overweight-obesity was in urban areas. Conclusion: The prevalence of malnutrition of primary schoolchildren in Binh Dinh was relatively high, in which the prevalence of overweight-obesity was rather high in urban areas and the prevalence of undernutrition was pretty high in mountainous area and midland. This study has characterized an important public health challenge, highlighting the need for attention to potential interventions. PMID- 30280113 TI - Emergency department performances during overcrowding: the experience of the health protection agency of Brianza. AB - Background: Hospital emergency departments (ED) can contribute to improve health outcomes and reduce costs of health care system. This study evaluated ED admissions during a twelve months period, analyzing characteristics of patients who underwent to emergency care in order to understand factors involved in ED overcrowding and promote adequate management. Methods: This retrospective study analyzed a twelve months window, with in-depth focus on December/January when almost all EDs reported overcrowding. All ED admissions were recorded in electronic schedules including: demographic characteristics, time/date of the access, incoming triage code, diagnosis, performed procedures, discharge, time/date of discharge. A backward multivariable logistic regression model was used to estimate relationships between investigated variables and ED pattern mortality. Results: A total of 416,299 ED admissions were analyzed. During the overcrowded period there was an increase in patients admissions (+32 patients per day, p = 0.0079) with a statistically significant rise of critical patients (+1.7% yellow codes and +0.7% red codes, p < 0.001) and older subjects (+1.4% patients aged 75 or more years, p < 0.001). Moreover, there were statistically significant increases in waiting times and in length of visits, a higher percentage of patients who were hospitalized (13.3% vs. 12.2%, p < 0.001), left ED (4.46% vs. 4.15%, p < 0.001) and died (0.27% vs. 0.17%, p < 0.0001). This latter result maintained a marginal statistical significance (OR = 1.16, 95% CI = 0.98-1.38, p = 0.075) after adjustment for confounding. Conclusion: Our study highlights that ED crowding can determine measurable worsening in ED services and patient outcomes as mortality, waiting times, lengths of stay, percentage of abandonment without being seen and, probably, costs. Thus, address ED crowding has to be considered an important public health priority requiring policymakers involvement. PMID- 30280114 TI - Impact of online, video-based wellness training on Girl Scout leaders' wellness promotion self-efficacy, intention, and knowledge: A pilot randomized controlled trial. AB - Objective: To examine the effectiveness of tailored, online, video-based training on Girl Scout troop leaders' wellness promotion self-efficacy, intention, and knowledge regarding physical activity and fruit and vegetable practices during troop meetings. Design: Randomized controlled trial. Methods: Thirty Girl Scouts leaders were randomized to control (CON; n = 16) or intervention (INT; n = 14) conditions. INT leaders received six online weekly training videos on implementation of physical activity (PA) and fruit and vegetable (FV) practices during troop meetings. Videos addressed leader-identified improvement areas and strategies to overcome barriers. Leaders set PA and FV goals for upcoming meetings and self-monitored their progress. Questionnaires were completed at baseline and post-intervention on leaders' task and barrier self-efficacy, intention, and knowledge regarding meeting-time PA and FV practices. Results: INT leaders increased PA practices barrier self-efficacy (INT = 16.5 +/- 24.1%, CON = -4.8 +/- 21.5%; p = 0.036), vegetable practices self-efficacy (INT = 10.3 +/- 13.3%, CON = -3.5 +/- 28.9%; p = 0.049), and FV practices barrier self-efficacy (INT = 12.4 +/- 4.6%, CON = 1.6 +/- 28.7%; p = 0.036), when compared to CON leaders. There were no changes (p > 0.05) in PA or FV knowledge. Conclusions and implications: Results suggest the potential for using online video-based training for improvements in wellness-promoting practices of Girl Scout troop leaders.

AB - Background and aim: 'Reasoning 4 Change' (R4C) is a newly developed instrument, including four domains (D1-D4), to assess clinical practitioners' and students' clinical reasoning with a focus on clients' behaviour change in a physiotherapy context. To establish its use in education and research, its psychometric properties needed to be evaluated. The aim of the study was to generate criterion scores and evaluate the reliability and construct validity of a web-based version of the R4C instrument. Methods: Fourteen physiotherapy experts and 39 final-year physiotherapy students completed the R4C instrument and the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT). Twelve experts and 17 students completed the R4C instrument on a second occasion. The R4C instrument was evaluated with regard to: internal consistency (five subscales of D1); test retest reliability (D1-D4); inter-rater reliability (D2-D4); and construct validity in terms of convergent validity (D1.4, D2, D4). Criterion scores were generated based on the experts' responses to identify the scores of qualified practitioners' clinical reasoning abilities. Results: For the expert and student samples, the analyses demonstrated satisfactory internal consistency (alpha range: 0.67-0.91), satisfactory test-retest reliability (ICC range: 0.46-0.94) except for D3 for the experts and D4 for the students. The inter-rater reliability demonstrated excellent agreement within the expert group (ICC range: 0.94-1.0). The correlations between the R4C instrument and PABS-PT (r range: 0.06 0.76) supported acceptable construct validity. Conclusions: The web-based R4C instrument shows satisfactory psychometric properties and could be useful in education and research. The use of the instrument may contribute to a deeper understanding of physiotherapists' and students' clinical reasoning, valuable for curriculum development and improvements of competencies in clinical reasoning related to clients' behavioural change. PMID- 30280117 TI - Behavioral risk factor clusters among university students at nine universities in Libya. AB - Objectives: This study identifies and describes the clustering of 5 behavioral risk factors (BRFs) among university students. We also investigated whether cluster membership is associated with the students' self-rated academic performance and self-rated health. Material and methods: A sample of 1300 undergraduates at 6 universities and 3 colleges in Libya completed a self administered questionnaire that assessed BRFs (nutrition, physical activity, alcohol consumption, smoking, illicit drug use, inadequate sleep). A two-step cluster analysis generated student clusters with similar lifestyles. Results: Two contrasting clusters of almost even size emerged (after exclusion of alcohol and illicit drug use due to very low prevalence). Cluster 1 comprised students with higher engagement in all forms of physical activity, higher levels of health consciousness, greater daily fruit/vegetable intake and better sleep patterns than students in cluster 2. Only as regards the consumption of sweets, cluster 1 students had less favorable practices than cluster 2 students. The prevalence of smoking was equally low in both clusters. Students in cluster 2, depicting a less healthy lifestyle, were characterized by a higher proportion of women, of students with less income and of higher years of study. Belonging to cluster 2 was associated with lower self-rated health (OR: 0.46, p < 0.001) and with lower self-rated academic performance (OR: 0.66, p < 0.001). Conclusion: Preventive programs should not address BRFs in isolation and should particularly target students with clustering of BRFs using specifically tailored approaches.

AB - Background: blood products is an interesting term as all blood and blood transfusion procedures carry risk even with advance screening of donors and donated blood. In Saudi Arabia voluntary donors are either the only source or not, the other source is paid donors and the lack of volunteers represents a major challenge. This is usually attributed to low community awareness regarding voluntary blood donation. Therefore, the objective of this study was to assess the levels of awareness towards blood donation in northern Saudi Arabia. Methodology: in this descriptive cross sectional survey, data about blood donation were obtained from 717 Saudi volunteers living in the city of Hail, Saudi Arabia. A Purposeful questionnaire was designed and used for obtaining of the necessary data. Results: When asking the participants to rate the level of awareness about blood donation in Saudi Society, the majority of participants categorized the levels as good followed by very good and poor, representing 48.8%, 29.3%, and 22% participants, respectively. Conclusion: the broad concept of blood donation is still poor in Saudi Arabia. Further educational plans are needed to raise the level of awareness and increase the perception of blood donation among Saudi population. Efforts should be made to involve females in blood donation duties. PMID- 30280116 TI - Review of the prevalence of postnatal depression across cultures. AB - The purpose of this review was to examine articles related to recent epidemiological evidence of the prevalence of maternal postnatal depression (PND) across different countries and cultures and to identify specific epidemiological studies that have been carried out exclusively in Malaysia on the prevalence of maternal PND. The review was undertaken in two stages, an initial review and an updated review. At both stages systematic literature searches of online databases were performed to identify articles on the prevalence of maternal PND. A total of 124 articles concerning research conducted in more than 50 countries were included in the final analysis. There were wide variations in the screening instruments and diagnostic tools used although the Edinburgh Postnatal Depression Scale (EPDS) was the most common instrument applied to identify PND. The prevalence of maternal PND ranged from 4.0% to 63.9%, with Japan and America recording the lowest and highest rates, respectively. Within continents, a wide variation in reported prevalence was also found. The reported rates of maternal PND in Malaysia were much higher than that previously documented with a range of 6.8-27.3%. This review indicated that the widely cited prevalence of maternal PND of 10-15% underestimates rates of PND worldwide. The reasons for this variability may not be fully explained by review methods. Future studies should evaluate the nature of women's PND experiences across cultures to explain these wide variations. PMID- 30280120 TI - A Qualitative Study of the Real-world Experiences of Infectious Diseases Fellows Regarding Antibiotic Stewardship. AB - Background: Antibiotic-resistant bacterial infections are a major threat to public health, yet improper use of antibiotics remains high. Infectious Diseases (ID) fellows play a major role in antibiotic stewardship efforts, but there is little research on how they view stewardship activities. We performed a qualitative study to explore ID fellows' experiences and perspectives regarding their antibiotic stewardship training and their role as future antibiotic stewards. Methods: We conducted 17 in-depth interviews with ID fellows across the country. The interviews were transcribed verbatim by the study team, and we used grounded theory to generate themes from these interviews. Results: Fellows focused on concrete tasks of stewardship such as performing antibiotic approvals, didactic and case-based education, and interactions with other physicians and pharmacists. There was little focus on the broader public health relevance of antibiotic stewardship. Pharmacists, not ID physician leaders, were identified as fellows' primary resource for antibiotic teaching. Several fellows suggested that stewardship programs should be led by pharmacists. Conclusions: ID fellowship training is not successfully conveying the public health importance of antibiotic stewardship or the role of ID physicians as leaders of antibiotic stewardship programs. Fellows are more focused on concrete tasks related to stewardship. ID training programs and societies should consider developing robust curricula involving fellows in the operation of the stewardship program itself, not solely in antibiotic approvals, emphasizing aspects of the program such as complex problem solving that fellows find most compelling, and emphasizing the important role these programs serve in improving public health. PMID- 30280118 TI - Paternal race/ethnicity and risk of adverse birth outcomes in the United States, 1989-2013. AB - Objectives: Investigate adverse birth outcomes in the United States (US) from 1989-2013 in relation to paternal and maternal race/ethnicity. Design: We used US natality data for singleton births to women 15-44 with information on birthweight, gestational age, and covariates (n = 90,771,339). We calculated unadjusted and adjusted probabilities of preterm birth (PTB, < 37 weeks gestation) and small for gestational age (SGA, < 10th percentile) among all combinations of maternal and paternal race/ethnicity: non-Hispanic black (NHB), non-Hispanic white (NHW), Hispanic, and Asian, and where paternal race/ethnicity was missing. Results: Missing, followed by NHB, paternal race/ethnicity had the two highest risks of PTB within each maternal racial/ethnic group. Asian, followed by NHW, paternal race/ethnicity had the two lowest risks of PTB. For SGA, however, Asian, followed by missing, paternal race/ethnicity had the two highest risks, and NHW race/ethnicity had the lowest risk. Our findings also demonstrate effect modification on the additive scale, with missing and NHB paternal race/ethnicity conferring a larger increase in risk of PTB for NHB women compared to women of other race/ethnicity groups. Conclusions: These data confirm US disparities in adverse birth outcomes by maternal and paternal race/ethnicity and argue for increased resources and interventions in response. PMID- 30280122 TI - Alternative REST Splicing Underappreciated. PMID- 30280121 TI - Characterizing the Short-Term Habituation of Event-Related Evoked Potentials. AB - Fast-rising sensory events evoke a series of functionally heterogeneous event related potentials (ERPs). Stimulus repetition at 1 Hz induces a strong habituation of the largest ERP responses, the vertex waves (VWs). VWs are elicited by stimuli regardless of their modality, provided that they are salient and behaviorally relevant. In contrast, the effect of stimulus repetition on the earlier sensory components of ERPs has been less explored, and the few existing results are inconsistent. To characterize how the different ERP waves habituate over time, we recorded the responses elicited by 60 identical somatosensory stimuli (activating either non-nociceptive Abeta or nociceptive Adelta afferents), delivered at 1 Hz to healthy human participants. We show that the well-described spatiotemporal sequence of lateralized and vertex ERP components elicited by the first stimulus of the series is largely preserved in the smaller amplitude, habituated response elicited by the last stimuli of the series. We also found that the earlier lateralized sensory wave habituates across the 60 trials following the same decay function of the VWs: this decay function is characterized by a large drop at the first stimulus repetition followed by smaller decreases at subsequent repetitions. Interestingly, the same decay functions described the habituation of ERPs elicited by repeated non-nociceptive and nociceptive stimuli. This study provides a neurophysiological characterization of the effect of prolonged and repeated stimulation on the main components of somatosensory ERPs. It also demonstrates that both lateralized waves and VWs are obligatory components of ERPs elicited by non-nociceptive and nociceptive stimuli.

PMID- 30280124 TI - There's an App for That; Improving Communication during Pediatric Cardiothoracic Surgery. AB - Introduction: Waiting while a loved one is in surgery can be a very stressful time. Current processes for updating families vary from institution to institution. Providing timely and relevant updates, while important to the family, may strain a surgical team's operational system. In our initial experience with the Electronic Access for Surgical Events (EASE) application (app), we tested the extent to which its implementation improved communication with patient families. Methods: We compared compliance data collected pre-EASE (December 2013 through September 2014) and post-EASE implementation (October 2014 until December 2015). Results: Although the pre-EASE compliance rate for bi hourly updates was 46% (118/255) of cases, post-EASE implementation achieved a compliance rate of 97% (171/176). A 2-sample test of proportions confirmed a significant improvement in compliance after the introduction of EASE technology (P < 0.001). Analysis of the 177 noncompliant cases in the pre-EASE period indicated that noncompliance occurred most frequently at the end of the case (97/177, 55%) when the patient remained in the operating room > 2 hours after the last update to the family. We also observed noncompliance at the beginning of the case (46/177, 26%), when the patient arrived in the operating room > 2 hours before the time of the first update. Family satisfaction scores that rated their experience during surgery as "Very Good" improved from 80% pre-EASE implementation to 97% postimplementation. We sustained this improvement for 1 year. Conclusions: A mobile technology app (EASE) improved both frequency and compliance with surgical updates to families, which resulted in a statistically significant increase in family satisfaction scores. PMID- 30280125 TI - The Effect of Operating Room Temperature on the Performance of Clinical and Cognitive Tasks. AB - Introduction: Operating room (OR) temperature may impact the performance of health care providers. This study assesses whether hot or cold room temperature diminishes the performance of OR personnel measured by psychomotor vigilance testing (PVT) and self-report scales. Methods: This prospective observational study enrolled surgical/anesthesia trainees, student registered nurse anesthetists, and certified registered nurse anesthetists. Each provider participated in a test of psychomotor function and a questionnaire using a self report scale of personal comfort and well-being. The PVT and questionnaires were completed after 30 minutes of exposure to 3 different conditions (temperature of 21 degrees C, 23 degrees C, and 26 degrees C). Results: The cohort of 22 personnel included 9 certified registered nurse anesthetists, 7 anesthesia/surgical trainees, and 6 student registered nurse anesthetists. Mean reaction time on the PVT was comparable among baseline (280 +/- 47 ms), hot (286 +/- 55 ms; P = 0.171), and cold (303 +/- 114 ms; P = 0.378) conditions. On the self-report score (range, 1-21), there was no difference in the self-rated subjective performance between baseline and cold conditions. However, the self rated subjective performance scale was lower (12 +/- 6, P = 0.003) during hot conditions. Discussion: No difference was noted in reaction time depending on the temperature; however, excessive heat in the OR environment was associated with worse self-rated subjective performance among health care providers. Particularly, self-rated subjective physical demand and frustration were greater under hot condition.

PMID- 30280126 TI - 10,000 Good Catches: Increasing Safety Event Reporting In A Pediatric Health Care System. AB - Background: In 2014, Children's National Health System's executive leadership team challenged the organization to double the number of voluntary safety event reports submitted over a 3-year period; the intent was to increase reliability and promote our safety culture by hardwiring employee event reporting. Methods: Following a Donabedian quality improvement framework of structure, process, and outcomes, a multidisciplinary team was formed and areas for improvement were identified. The multidisciplinary team focused on 3 major areas: the perceived ease of reporting (ie, how difficult is it to report an event?); the perceived safety of reporting (ie, will I get in trouble for reporting?); and the perceived impact of reporting (ie, does my report make a difference?) technology, making it safe to report, and how reporting makes a difference. The team developed a key driver diagram and implemented interventions designed to impact the key drivers and to increase reporting. Results: Children's National increased the number of safety event reports from 4,668 in fiscal year 2014 to 10,971 safety event reports in fiscal year 2017. Median event report submission time was decreased by nearly 30%, anonymous reporting decreased by 69%, the number of submitting departments increased by 94%, and the number of reports submitted as "other" decreased from a baseline of 6% to 2%. Conclusions: Children's National Health System's focus on increasing safety event reporting resulted in increased organizational engagement and attention. This initiative served as a tangible step to improve organizational reliability and the culture of safety and is readily generalizable to other hospitals. PMID- 30280127 TI - Impact of a Hands-free Wireless Communication Device on Communication and Clinical Outcomes in a Pediatric Intensive Care. AB - Introduction: Timely communication is essential in the intensive care environment. Delays may occur if communication relies on identification of individuals through line of sight, or use of telephones and pagers. We measured communication delays, staff perceptions, and clinical outcomes before and after implementation of a hands-free wireless communication device (HWCD) in a pediatric intensive care unit (PICU). Methods: Single-center study comprising 3 components: observational study of verbal communication among PICU staff; staff survey regarding perceptions of communication delays; analysis of clinical data (length of stay, risk adjusted mortality, emergency events). All components were conducted before and after implementation of the HWCD. Results: Four hundred sixteen hours of staff working time were observed (210 pre- and 206 postimplementation). These data showed significant reduction in communication delays-most notably among roaming staff [median time to response to verbal queries before and after implementation 120 seconds (interquartile range, 6-255) and 9 seconds (interquartile range, 7-30), respectively: P < 0.001]. The results of the staff survey showed significant improvements in staff perceptions of communication delays in all roaming staff groups utilizing the HWCD. The survey response rate was 205/361: 56.8%. There were no differences in clinical outcomes from the routinely collected clinical data. There was a significant reduction in emergency event rate-emergency summoning of assistance to bedside (per 100 bed days)-before and after implementation, 2.17 and 1.69, respectively: rate ratio = 0.78 (95% confidence interval, 0.63-0.95; P < 0.05). Conclusions: Implementation of a HWCD was associated with significant reduction in communication delays among roaming staff members in PICU. PMID- 30280129 TI - Essential Amino Acid Supplementation Mitigates Muscle Atrophy After Total Knee Arthroplasty: A Randomized, Double-Blind, Placebo-Controlled Trial. AB - Background: Substantial muscle atrophy occurs after total knee arthroplasty (TKA), resulting in decreased strength and impaired mobility. We sought to determine whether perioperative supplementation with essential amino acids (EAA) would attenuate muscle atrophy following TKA and whether the supplements were safe for ingestion in an older surgical population. Methods: We performed a double-blind, placebo-controlled, randomized trial of 39 adults (age range, 53 to 76 years) undergoing primary unilateral TKA who ingested 20 g of EAA (n = 19) or placebo (n = 20) twice daily for 7 days preoperatively and for 6 weeks postoperatively. At baseline and 6 weeks postoperatively, magnetic resonance imaging (MRI) scans were obtained to measure quadriceps and hamstrings muscle volume. Secondary outcomes included functional mobility and strength. Data on physical activity, diet, and patient-reported outcomes (Veterans RAND 12-Item Health Survey and Knee injury and Osteoarthritis Outcome Score) were collected. Safety was determined through blood tests evaluating blood urea nitrogen, creatinine, creatinine clearance, homocysteine, and renal and liver function. Laboratory values at baseline, on the day of surgery, and at 2 days, 2 weeks, and 6 weeks postoperatively were compared between treatment groups. Analysis of covariance models, with baseline values as covariates, were used to evaluate outcomes between treatment groups. P values were adjusted for multiple tests. Results: Compared with baseline, the EAA group had significantly less decrease in mean quadriceps muscle volume compared with the placebo group in the involved leg (-8.5% +/- 2.5% compared with -13.4% +/- 1.9%; p = 0.033) and the contralateral leg (-1.5% +/- 1.6% compared with -7.2% +/- 1.4%; p = 0.014). The hamstrings also demonstrated a greater muscle-volume-sparing effect for the EAA group than for the placebo group in the involved leg (-7.4% +/- 2.0% compared with -12.2% +/- 1.4%; p = 0.036) and contralateral leg (-2.1% +/- 1.3% compared with -7.5% +/- 1.5%; p = 0.005). There were no differences between the groups in terms of functional measures or strength. Blood chemistry values varied significantly between assessments periods but did not statistically differ between groups. Conclusions: The results of the present study suggest that EAA supplementation is safe and reduces the loss of muscle volume in older adults recovering from TKA.

PMID- 30280130 TI - Patients at the Highest Risk for Reherniation Following Lumbar Discectomy in a Multicenter Randomized Controlled Trial. AB - Background: The purposes of the present study were to (1) confirm the risk of recurrent lumbar disc herniation in patients with a large anular defect who had undergone limited discectomy and (2) assess potential risk factors within this population. Methods: The patient population was extracted from the control cohort of a prospective, randomized, multicenter controlled trial investigating the efficacy of an anular closure device following standard limited discectomy. All control patients underwent limited discectomy for the treatment of a single-level symptomatic posterior or posterolateral lumbar disc herniation. Only patients presenting with a large anular defect (6 to 10 mm wide by 4 to 6 mm long) were included in the study (n = 278). Baseline demographic, clinical, and surgical characteristics were recorded. Follow-up evaluations were performed at 6 weeks and at 3, 6, 12, and 24 months. Imaging modalities included magnetic resonance imaging, low-dose computed tomography, and radiographs. Symptomatic recurrent lumbar disc herniation was defined as any symptomatic postoperative herniation on either side of the index level. A multivariate logistic regression analysis of demographic and surgical variables associated with the incidence of recurrent lumbar disc herniation was performed. Results: The mean anular defect area (and standard deviation) was 39.3 +/- 9.1 mm2, and the mean excised nuclear tissue volume was 1.3 +/- 0.8 mL. At 2 years, the incidence of symptomatic recurrent lumbar disc herniation was 25.3% (64 of 253), with the herniation occurring at a mean of 264 days after the index procedure. Of the 64 patients with recurrent lumbar disc herniation, 36 underwent a subsequent surgical procedure. Logistic regression analysis identified an increased risk for recurrent lumbar disc herniation in females (odds ratio, 2.2) and in patients with greater anular defect widths (odds ratio, 1.3). Furthermore, multivariate logistic regression analyses revealed a significant interaction between age and sex (p = 0.005). Conclusions: The outcomes of the present study provide the most substantial evidence to date in confirming previous reports of a high risk of reherniation among patients with large anular defects. Among those with large anular defects (width, >=6 mm), females <=50 years of age had the highest risk (up to ~10 times higher) of recurrent lumbar disc herniation. It is recommended that an anular repair or closure should be performed after limited discectomies in patients with large anular defects. Level of Evidence: Therapeutic Level IV.

PMID- 30280131 TI - Incidence and Characterization of Major Upper-Extremity Amputations in the National Trauma Data Bank. AB - Background: There are few recent data examining the epidemiology of severe upper extremity trauma in non-military patients. We used the National Trauma Data Bank (NTDB) to investigate the epidemiology and descriptive characteristics of upper extremity amputations in U.S. trauma centers. Methods: We queried the 2009 to 2012 NTDB research datasets for patients undergoing major upper-extremity amputation and extracted characteristics of the patient population, injury distribution, and treating facilities. In addition, multivariable regression models were fit to identify correlates of reoperation, major in-hospital complications, duration of hospitalization, and in-hospital mortality. Results: A total of 1,386 patients underwent a major upper-extremity amputation secondary to a trauma-related upper-extremity injury, representing 46 per 100,000 NTDB trauma admissions from 2009 to 2012. The most frequent definitive procedures performed were amputations through the humerus (35%), forearm (30%), and hand (14%). The average duration of hospitalization for all amputees was 17 days. Thirty-one percent of patients underwent at least 1 reoperation. The rate of reoperation was significantly higher at university-associated hospitals compared with nonteaching or community hospitals (p < 0.0001). Patients who had at least 1 reoperation stayed in the hospital approximately 7 days longer than patients who did not undergo reoperation. The Injury Severity Score, hospital teaching status, concomitant neurovascular injury, and occurrence of a complication were significantly associated with reoperation. Conclusions: The present study provides an updated report on the epidemiology and characteristics of trauma related major upper-extremity amputation in the U.S. civilian population. Additional work is necessary to assess the long-term outcomes following attempted upper-extremity salvage. The population-level data provided by the present study may help to inform the design and implementation of future studies on the optimum treatment for this survivable but life-altering injury. PMID- 30280132 TI - The Effect of Age, Sex, Area Deprivation, and Living Arrangements on Total Knee Replacement Outcomes: A Study Involving the United Kingdom National Joint Registry Dataset. AB - Background: Total knee replacement (TKR) is a common procedure for the treatment of osteoarthritis that provides a substantial reduction of knee pain and improved function in most patients. We investigated whether sociodemographic factors could explain variations in the benefit resulting from TKR. Methods: Data were collected from 3 sources: the National Joint Registry for England, Wales, Northern Ireland, and the Isle of Man; National Health Service (NHS) England Patient Reported Outcome Measures; and Hospital Episode Statistics. These 3 sources were linked for analysis. Pain and function of the knee were measured with use of the Oxford Knee Score (OKS). The risk factors of interest were age group, sex, deprivation, and social support. The outcomes of interest were sociodemographic differences in preoperative scores, 6-month postoperative scores, and change in scores. Results: Ninety-one thousand nine hundred and thirty-six adults underwent primary TKR for the treatment of osteoarthritis in an NHS England unit from 2009 to 2012. Sixty-six thousand seven hundred and sixty nine of those patients had complete knee score data and were included in the analyses for the present study. The preoperative knee scores were worst in female patients, younger patients, and patients from deprived areas. At 6 months postoperatively, the mean knee score had improved by 15.2 points. There were small sociodemographic differences in the benefit of surgery, with greater area deprivation (-0.71 per quintile of increase in deprivation; 95% confidence interval [CI], -0.76 to -0.66; p < 0.001) and younger age group (-3.51 for <=50 years compared with 66 to 75 years; 95% CI, -4.00 to -3.02; p < 0.001) associated with less benefit. Cumulatively, sociodemographic factors explained <1% of the total variability in improvement. Conclusions: Sociodemographic factors have a small influence on the benefit resulting from TKR. However, as they are associated with the clinical threshold at which the procedure is performed, they do affect the eventual outcomes of TKR. Level of Evidence: Prognostic Level IV.

AB - Background: Brachymetatarsia is usually treated by lengthening the metatarsals, but excessive lengthening can be associated with complications. Our technique combines 1-stage step-cut lengthening of the first metatarsal with shortening and/or lengthening of the neighboring metatarsals and/or phalanges. Methods: Twenty-four feet (15 patients) were treated for first-ray brachymetatarsia. Widely available commercial image-editing software was used to make a preoperative plan for each patient, with emphasis on the creation of a cosmetically satisfying toe-length arc with minimum shortening and lengthening of the affected metatarsals and proximal phalanges. Length gain and percentage increase were also recorded postoperatively. The American Orthopaedic Foot & Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal scoring system was used for clinical evaluation. Results: In all 24 feet, smooth parabolas were created at the level of the metatarsal heads and at the toe tips. All patients showed osseous union, and no complications were noted. However, most patients showed mildly restricted range of motion of the first metatarsophalangeal joint. The mean AOFAS score of the hallux significantly improved from 88.3 preoperatively to 98.1 at the latest follow-up (p < 0.001). Conclusions: One stage step-cut lengthening of the first metatarsal combined with shortening and/or lengthening of the adjacent metatarsal and phalangeal bones provides excellent cosmetic and functional results.

PMID- 30280135 TI - The Use of a Free Fibular Strut as a "Biological Intramedullary Nail" for the Treatment of Complex Nonunion of Long Bones. AB - Background: Nonunion of long-bone fractures is difficult to treat, especially when the bones are osteoporotic or there is a large bone gap as a result of repeated failure of the metallic nails or implants. In such cases, the use of an autologous intramedullary fibular strut graft may be a viable treatment option. Methods: Twenty-two patients with a complex nonunion of the shaft of the femur, humerus, or tibia were managed with a free autologous fibular strut graft for intramedullary fixation with use of closed or open methods. All patients had evidence of moderate to severe local osteoporosis and had a bone gap ranging from 4 to 20 mm. Nineteen patients had had 1 to 4 prior operations. The mean age was 51.5 years. The duration of nonunion ranged from 9 months to 4 years. Results: The mean time to union was 17 weeks (range, 8 to 26 weeks), and the mean duration of follow-up was 4 years (range, 6 months to 17 years). All but 2 patients had healing at the time of the latest follow-up. Conclusions: The identification of a viable option for the treatment of difficult nonunion in osteoporotic bones has been a challenge. The insertion of a free autologous intramedullary fibular strut graft provided mechanical stability, and osteogenesis occurred inside the medullary canal of the host bone.

PMID- 30280134 TI - Clinical Outcomes According to Femoral and Acetabular Version After Periacetabular Osteotomy. AB - Background: Patients with acetabular dysplasia often have abnormal femoral and acetabular version. The effect of combined femoral and acetabular version on clinical outcomes after periacetabular osteotomy for the treatment of acetabular dysplasia remains unclear. The purposes of the present study were (1) to evaluate the association of combined femoral and acetabular version with clinical outcome after periacetabular osteotomy and (2) to investigate the association of femoral version independently with clinical outcome after periacetabular osteotomy. Methods: We retrospectively reviewed the records for 92 consecutive patients (95 hips) who had undergone periacetabular osteotomy for the treatment of symptomatic acetabular dysplasia. The patient cohort comprised 85 females and 7 males with a mean age of 38.9 years at the time of surgery. The mean duration of follow-up was 4.8 years (range, 2.0 to 7.2 years). Femoral and acetabular version and the alpha angle were measured on postoperative computed tomography scans. Clinical outcomes included range of motion and the modified Harris hip score. Analysis of variance was used to investigate the effect of femoral version on clinical outcomes. Analysis of covariance was used to adjust for potential covariates. Results: Combined femoral and acetabular version after periacetabular osteotomy was slightly, but significantly, correlated with postoperative flexion (r = 0.222; p = 0.031) and internal rotation in flexion (r = 0.326; p = 0.001). Patients with mild femoral version (<15 degrees ) experienced significantly less postoperative internal rotation in flexion than those with severe femoral version (>35 degrees ); however, this difference was lost after adjustment for potential covariates. There were no differences among femoral version groups (mild, moderate, and severe) in terms of improvements in the clinical outcomes of pain, function, and activity. Conclusions: Combined femoral and acetabular version after periacetabular osteotomy was significantly correlated with postoperative range of motion. Abnormality of femoral version associated with acetabular dysplasia did not demonstrate any effect on the clinical outcomes of periacetabular osteotomy. Level of Evidence: Prognostic Level IV.

PMID- 30280136 TI - Patient Profiling Can Identify Spondylolisthesis Patients at Risk for Conversion from Nonoperative to Operative Treatment. AB - Background: Factors that are relevant to the decision regarding the use of surgical treatment for degenerative spondylolisthesis include disease-state severity and patient quality-of-life expectations. Some factors may not be easily appraised by the surgeon. In prospective trials involving patients undergoing nonoperative and operative treatment, there are instances of crossover in which patients from the nonoperative group undergo surgery. Identifying and understanding patient characteristics that may influence crossover from nonoperative to operative treatment will aid understanding of what motivates patients toward pursuing surgery. Methods: Patients with degenerative spondylolisthesis who were randomized to nonoperative care in a prospective, multicenter study were evaluated over 8 years of enrollment. Two cohorts were defined: (1) the surgery cohort (patients who underwent surgery at any point) and (2) the nonoperative cohort (patients who did not undergo surgery). A Cox proportional hazards model, modeling time to surgery, was used to explore demographic data, clinical diagnoses, and patient expectations and attitudes after adjusting for other variables. A subanalysis was performed on surgery within 6 months after enrollment and surgery >6 months after enrollment. Results: One hundred and forty-five patients who had been randomized to nonoperative treatment, 80 of whom crossed over to surgery, were included. In analyzing baseline differences between the 2 cohorts, patients who underwent surgery were younger; however, there were no significant difference between the cohorts in terms of race, sex, or comorbidities. Treatment preference, greater Oswestry Disability Index score, marital status, and no joint problems were predictors of crossover to surgery. Clinical factors, including stenosis, neurological deficits, and listhesis levels, did not show a significant relationship with crossover. At the time of long-term follow-up, the surgery cohort showed significantly greater long-term improvement in health-related quality of life (p < 0.001). The difference was maintained throughout follow-up. Conclusions: Neurological symptoms and diagnoses, including listhesis and stenosis severity, did not predict crossover from nonoperative care to surgery. Attitudes toward surgery, greater Oswestry Disability Index score, marital status, and no joint problems were independent predictors of crossover from nonoperative to operative care. Certain demographic characteristics were associated with higher rates of crossover, although they were connected to patient attitudes toward surgery. Level of Evidence: Prognostic Level II.

PMID- 30280137 TI - Restoration of External Rotation Following Reverse Shoulder Arthroplasty without Latissimus Dorsi Transfer. AB - Background: Latissimus dorsi transfers have been considered necessary to restore active external rotation following reverse shoulder arthroplasty (RSA). The purpose of this study was to assess the effectiveness of an RSA system that lateralizes the center of rotation in restoring active external rotation without a latissimus dorsi transfer in patients with a preoperative external rotation deficit (external rotation of <0 degrees ). Methods: We retrospectively reviewed the records of patients who had undergone RSA with a lateralized center of rotation without a latissimus dorsi transfer. All patients had had a preoperative external rotation deficit (active external rotation of <0 degrees ), and all were followed for a minimum of 2 years. Patients were stratified into 2 groups on the basis of the preoperative diagnosis: (1) those with a combined loss of active elevation and external rotation as a result of rotator cuff tear arthropathy (CLEER group) and (2) those with a combined loss of active elevation and external rotation as a result of other posttraumatic etiologies (non-CLEER group). The mean improvement of external rotation was analyzed. Subgroup analysis was performed on the basis of the Goutallier classification, glenosphere lateralization, and total prosthetic lateralization. Results: Thirty-three patients (24 in the CLEER group and 9 in the non-CLEER group) met the inclusion criteria. The average follow-up was 43.4 months (range, 24 to 77 months). External rotation improved significantly in both the CLEER group (from -21 degrees preoperatively to 28 degrees postoperatively; p < 0.001) and the non CLEER group (from -19 degrees preoperatively to 26 degrees postoperatively; p = 0.001). Goutallier classification, glenosphere lateralization, and total prosthetic lateralization were not correlated with the degree of improvement of external rotation in either group (p > 0.05 for all). Conclusions: RSA with a lateralized center of rotation can effectively restore external rotation without the use of a latissimus dorsi transfer in patients with a preoperative external rotation deficit as a result of rotator cuff arthropathy or other posttraumatic etiologies.

PMID- 30280138 TI - Characteristics of Benign and Malignant Bone Tumors Registered in the Hiroshima Tumor Tissue Registry, 1973-2012. AB - Background: Reported information on the characteristics of benign bone tumors is disjointed, and the long-term trends in the occurrence of malignant bone tumors by histological type have not been reported in Japan. Our aim was to describe the characteristics of both benign and malignant bone tumors as described in cases registered in the Hiroshima Tumor Tissue Registry from 1973 to 2012. Methods: Cases were identified with the International Classification of Diseases for Oncology (ICD-O-3) topography code C40-C41 (bones, joints, and articular cartilage), and histological types were classified according to the World Health Organization 2013 system. We described the distribution of the cases by behavior, sex, skeletal site of tumor occurrence, histological type, period at diagnosis (in 10-year groups), and age at diagnosis (in 10-year groups). Results: We observed 2,542 benign bone tumors, 272 intermediate bone tumors, and 506 malignant bone tumors. We confirmed that 81.6% of benign bone tumors were chondrogenic, consisting primarily of osteochondromas and enchondromas. Giant cell tumor of bone was the most dominant type of intermediate tumor, whereas osteogenic tumors and chondrogenic tumors were the most dominant types of malignant tumors. Among malignant bone tumors, 41.7% of tumors occurred in the long bones of the lower limb, and there were different peaks of age at the time of diagnosis for osteogenic tumors and chondrogenic tumors. A similar distribution of histological types was seen throughout the 40-year observation period. Conclusions: Osteochondroma and enchondroma differed in terms of the age of the patient at the time of diagnosis and the skeletal sites where the tumors most frequently occurred. Giant cell tumor had a large impact on occurrence as a common type of intermediate bone tumor. Clinical Relevance: The results of the present study, based on pathological tissue registry data, provide knowledge about the epidemiological and pathological features of bone tumors in Japan. PMID- 30280139 TI - Fifty Most-cited Articles on Lateral Epicondylitis of the Elbow. AB - Introduction: Citation number can be used as a marker of a scientific article's influence. This study sought to determine and characterize the most-cited investigations on lateral epicondylitis and identify the most influential studies pertaining to this pathology. Methods: The Institute for Scientific Information Web of Science database was queried for articles investigating lateral epicondylitis, and the 50 most-cited articles were selected. For each article, number of citations, citation density, journal, publication year, country of origin, language, article type, article subtype, and level of evidence were recorded. Results: Citation numbers ranged from 72 to 332 (mean, 127.4), and densities ranged from 1.6 to 34.0 (mean, 9.4). Articles were published across 26 different journals. Most articles (41) were clinical, with randomized controlled trials (29.3%) being the most commonly cited articles. Discussion: Compared with previous investigations looking at citation density within orthopaedics, the most commonly cited clinical articles on lateral epicondylitis had a high percentage of level I or II evidence (39.0%). This compilation of the literature can aid in establishing reading curriculums for trainees in both orthopaedic residencies and fellowships. This is a Level V study. PMID- 30280140 TI - Orthopaedic Academic Activity in the United States: Bibliometric Analysis of Publications by City and State. AB - Background: The purpose of this study was to conduct a bibliometric analysis of orthopaedic academic output in the United States. Methods: Publications based on city and state origin, corrected for population size, median household income, total number of surgeons, and the number of various subspecialties were evaluated. The 15 highest-ranked orthopaedic journals were audited from 2010 to 2014 and then subdivided into anatomic regions and 14 subspecialties. Results: A total of 8,100 articles were published during the study period. Most originated from New York, California, Pennsylvania, Massachusetts, and Minnesota. New York published the greatest number by city, followed by Philadelphia, Boston, Chicago, and Rochester. When adjusted for the number of publications per city, surgeons per population, publications per surgeon population, publications per population, and publications per median income per capita, Vail and New York led in two and Stanford in one of the metrics. Conclusions: New York was the leader for the total publications, greatest activity within subspecialties, and publications per surgeon/population and per median income/capita. Vail was the leader for publications/surgeon and population. The top four cities of New York, Philadelphia, Boston, and Chicago were responsible for 28% of the academic output over the 5-year study period. PMID- 30280141 TI - A High-fidelity Tactile Hand Simulator as a Training Tool to Develop Competency in Percutaneous Pinning in Residents. AB - Introduction: We developed an economical three-dimensional printed and casted simulator of the hand for the training of percutaneous pinning. This simulator augments the traditional "See one, do one, teach one" training model. Methods: To evaluate the simulator, five expert orthopaedic surgeons were recruited to perform percutaneous pinning on the simulator and then to complete a questionnaire on its realism and expected usefulness. Evaluation was based on responses to multiple-choice questions and a Likert-type scale. Results: All subjects expressed that the tactile hand simulator is useful for residency training. They would recommend the simulator to their colleagues and indicated interest in testing future iterations. Subjects rated highly the realism of the material, the purchase of the pin, and the cortical-cancellous bone interface. Conclusion: The learning of tactile skills in addition to visual cues on a tactile simulator is expected to benefit residents. It provides a low-cost and low-risk environment outside the operating room for residents to hone their skills. PMID- 30280142 TI - Patient Dose Comparison for Intraoperative Imaging Devices Used in Orthopaedic Lumbar Spinal Surgery. AB - Background: The aim of this study was to determine the amount of radiation exposure from intraoperative imaging during two-level and four-level lumbar fusions. Methods: Five imaging systems were studied: multidetector CT (MDCT) scanner (CT A); two mobile CT units (CT B and CT C); a C-arm (D); and fluoroscopy (E). Metal oxide semiconductor field effect transistor dosimeters measured doses at 25 organ locations using an anthropomorphic phantom. A fat-equivalent phantom was used to simulate an obese body mass index (BMI). Results: The effective dose (ED) for C-arm D was estimated using commercial software. The ED for others was computed from the measured mean organ doses. EDs for a normal BMI patient, receiving a four-level fusion, are as follows: CT A (12.00 +/- 0.30 mSv), CT B (5.90 +/- 0.25 mSv), CT C (2.35 +/- 0.44 mSv), C-arm D (0.44 mSv), and fluoroscopy E (0.30 +/- 0.3 mSv). The rankings are consistent across all three BMI values except CT C and fluoroscopy E, which peaked in the overweight size because of system limitations. The other machines' ED trended with patient BMI. Conclusion: The dose reduction protocols were confirmed according to the manufacturer's specifications. The results of this study emphasize the need for the appropriate selection of the imaging system, especially because the type of device could have a substantial effect on patient radiation risk. PMID- 30280143 TI - Idiopathic Charcot Arthropathy of the Knee Presenting as a Bicondylar Tibial Plateau Fracture. AB - Charcot arthropathy is an infrequent condition that primarily involves the foot and ankle; rarely, it has been reported to affect the knee. Risk factors for Charcot arthropathy are well described with diabetes being the most common cause. Idiopathic Charcot arthropathy without a secondary etiology is extremely rare, with only a few cases described involving the foot and shoulder. Clinically, idiopathic Charcot arthropathy presents a notable challenge because delayed diagnosis can lead to surgical complications and advancement of joint destruction. We report idiopathic Charcot arthropathy of the knee presenting as a bicondylar tibial plateau fracture successfully managed with total knee arthroplasty after failed open reduction internal fixation. We diagnosed the patient when the clinical/surgical presentation was indicative of Charcot arthropathy and after excluding all other diagnoses. This previously unreported case describes the complexity of idiopathic Charcot arthropathy with subsequent fractures and highlights the importance of patient history, presentation, and surgical intervention.

PMID- 30280145 TI - Pyogenic Sacroiliitis in a Pediatric Patient: A Rare Case of Infection by Streptococcus intermedius. AB - This is a case report of pyogenic sacroiliitis in a pediatric patient caused by Streptococcus intermedius. The patient is a 16-year-old boy who presented to an emergency department with sudden onset of back pain radiating to the left lower extremity. The diagnosis was confounded by the presence of isthmic spondylolisthesis. Plain radiography demonstrated mild isthmic spondylolisthesis but no radiographic signs of tumor, trauma, infection, arthritis, or other developmental problems. The C-reactive protein level was 23 mg/L. Over the next 24 hours, the patient developed fever, and the C-reactive protein level increased to 233 mg/L. Sacroiliitis and an iliopsoas abscess were identified on MRI. Blood cultures grew S intermedius. The patient responded to antibiotic treatment and needle aspiration under CT guidance. Sacroiliitis is an uncommon condition and, to our knowledge, there is only one other case report of its being caused by S intermedius. The previous report was in an adult. PMID- 30280147 TI - Microbiota-accessible pectic poly- and oligosaccharides in gut health. AB - Diverse human intestinal microbiota are regarded as a prerequisite for a healthy intestine. Commercial prebiotic products have a limited ability to provide microbial diversity in the human gut, because they mostly comprise oligomers of the same monosaccharide residues and a small fraction of them can reach the distal colon. Therefore, the demand for diverse prebiotic ingredients and dietary fibers with improved functional properties is increasing tremendously. The main sources of carbohydrates in our diet are plant-derived polysaccharides, which are consumed by the bacteria present in the intestine. Among these, pectin-derived poly- and oligosaccharides serve as the best alternative, as they are resistant to human gastric juice and are fermented slowly in the large intestine to impart a prebiotic effect. The main components of pectin are polygalacturonic acids in association with neutral polysaccharides such as arabinan, arabinogalactan, and galactan. The present review deals with the health-related functional properties of pectic poly- and oligosaccharides and their applications in the food industry. Different mechanisms involved in the hydrolysis of these carbohydrates by the intestinal bacteria and in maintaining the microbial diversity of the intestine are also discussed. It also emphasizes the current methods for the production and purification of different pectins and their oligosaccharides. PMID- 30280146 TI - Reliability and Construct Validity of the Adapted Norwegian Version of the Early Onset Scoliosis 24-item Questionnaire. AB - Background: The Early-Onset Scoliosis 24-item Questionnaire (EOSQ-24) reflects issues important for patients with early-onset scoliosis (EOS) and their parents. The aim of this study was to translate the original EOSQ-24 into Norwegian and to evaluate the resulting questionnaire's reliability and construct validity. Methods: The EOSQ-24 was translated using a forward-backward translation method, followed by an expert review. One hundred parents of a heterogenic group of patients with EOS answered the EOSQ-24 and scored Numeric Rating Scales (NRSs) to evaluate the children's general health, pain, and physical function. Two weeks later, 55 parents (55%) answered the retest questionnaire. Data quality, internal consistency, and test-retest reliability were assessed, including the minimal detectable change. Construct validity was evaluated by predefined hypotheses and correlations with NRS scores. Results: There were considerable ceiling (19.0% to 63.0%) and floor effects (zero to 26.0%). The internal consistency was excellent (Cronbach alpha = 0.95). The minimal detectable change for the EOSQ-24 total score was 15.2 and ranged from 21.6 to 33.0 for the subdomains scores. The EOSQ 24 showed discriminate capabilities among patients with different etiology, treatment status, and severity of deformity. High correlations were found between the EOSQ-24 total score and the NRS scores for general health (r = -0.66), pain (r = -0.63), and physical function (r = -0.78). Conclusion: The Norwegian version of the EOSQ-24 has acceptable reliability and validity for measuring quality of life and caregiver burden among EOS children. The EOSQ-24 total score is acceptable for evaluation of these patients over time. Level of Evidence: Level III, diagnostic study. PMID- 30280148 TI - MOF based on a longer linear ligand: electrochemical performance, reaction kinetics, and use as a novel anode material for sodium-ion batteries. AB - A metal-organic framework based on a longer linear ligand was rationally designed and evaluated as a novel anode material for sodium-ion batteries. It delivered a high specific capacity of 269 mA h g-1 with a desired voltage plateau and demonstrated excellent capacity retention (79.0% after 1000 cycles). In addition, its reaction kinetics was also investigated in detail by performing cyclic voltammetry and a predominantly diffusion-controlled process was clearly revealed. PMID- 30280149 TI - Characterization of phenolic compounds in tincture of edible Nepeta nuda: development of antimicrobial mouthwash. AB - The activity of edible Nepeta nuda L. (Lamiaceae) tincture and Listerine towards a selected group of oral pathogenic microorganisms (4 bacterial and 9 fungal strains) has been explored. Their potentials to inhibit the formation of biofilm and to diminish established biofilm have been compared. The amount of N. nuda tincture and swishing time necessary for reaching better or equivalent antimicrobial effect than that of Listerine have been predicted. Phenolic compounds in N. nuda tincture are determined by LC-DAD/ESI-MSn. Both Listerine and N. nuda tincture possess good antimicrobial potentials (MIC in the range of 0.8-15 MUL per well) including inhibition of biofilms. Rosmarinic acid and verminoside are the most dominant phenolic compounds present in the N. nuda tincture. Based on in vitro results, we infer that it is more desirable to swish 20 mL of mouthwashes (Listerine and N. nuda tincture, 100 mg mL-1) for 30 s when dealing with selected microorganisms in general and for 60 s (N. nuda tincture) when dealing with bacterial biofilms. PMID- 30280150 TI - Polymerization led selective detection and removal of Zn2+ and Cd2+ ions: isolation of Zn- and Cd-MOFs and reversibility studies. AB - This work illustrates two post-functionalized chemosensors and their remarkable role in the sensing of Zn2+ and Cd2+ ions via producing the corresponding insoluble metal-organic frameworks (MOFs). The structural characterization of the resultant Zn- and Cd-MOFs revealed their polymeric one- or two-dimensional architectures. Importantly, nitrate and nitrite ions reversed the MOF polymerization process and regenerated the chemosensors and the corresponding metal salts. These results are significant in terms of recyclability and remediation processes for the removal of metals both from living organisms and the environment. PMID- 30280151 TI - Electrolyte solvents for high voltage lithium ion batteries: ion correlation and specific anion effects in adiponitrile. AB - We studied dynamic and structural properties of two lithium conducting salts in the aprotic organic solvent adiponitrile by a combination of atomistic molecular dynamics (MD) simulations, quantum chemical calculations, and experimental findings. The outcomes of our simulations reveal significant differences between both lithium salts, namely lithium tetrafluoroborate (LiBF4) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) at various concentrations, which can be mainly attributed to the solvation behavior of the individual anions. The increased tendency of ion complex formation for LiBF4 is reflected by lower values regarding the measured and computed effective ionic conductivities when compared to LiTFSI. All findings highlight the crucial importance of specific anion effects in combination with molecular details of solvation, and advocate the use of adiponitrile as a beneficial solvent in modern lithium ion battery technology with high voltage electrodes. PMID- 30280152 TI - Assembled anti-adhesion polypropylene mesh with self-fixable and degradable in situ mussel-inspired hydrogel coating for abdominal wall defect repair. AB - Abdominal adhesion to polypropylene (PP) mesh remains one of the major complications in hernia repair. Thus, a challenge exists to endow PP mesh with powerful anti-adhesion properties in hernia repair. To investigate potential options, the assembled PP mesh was developed with effective anti-adhesion properties through an in situ coating of the mesh surface with self-fixable and biodegradable mussel-inspired hydrogels. Through mixing oxidized carboxymethylcellulose functionalized with dopamine (OCMC-DA) with carboxymethylchitosan (CMCS), a layer of hydrogel (OCMC-DA/CMCS) can be formed in situ on the PP mesh without the addition of crosslinking agents; the dopamine then acts as an immobilization group to fix these hydrogels to the PP mesh and the tissue surface. In this way, the assembled PP mesh (OCMC-DA/CMCS/PP) was obtained. The properties of the OCMC-DA/CMCS hydrogels were optimized, and the OCMC-DA4/CMCS hydrogel was selected to construct the assembled PP mesh. The lap shear test revealed that OCMC-DA4/CMCS has tissue-adhesive properties. In vitro cell tests proved the excellent biocompatibility of the hydrogel. An optimized bioabsorption time and significant anti-adhesion properties were demonstrated through an in vivo test with a rat model. The adhesion area and tenacity of the OCMC-DA4/CMCS/PP group were more than 80% lower than those of the native PP mesh group and created a slightly inflammatory reaction.

PMID- 30280154 TI - Engineering enzymes for noncanonical amino acid synthesis. AB - The standard proteinogenic amino acids grant access to a myriad of chemistries that harmonize to create life. Outside of these twenty canonical protein building blocks are countless noncanonical amino acids (ncAAs), either found in nature or created by man. Interest in ncAAs has grown as research has unveiled their importance as precursors to natural products and pharmaceuticals, biological probes, and more. Despite their broad applications, synthesis of ncAAs remains a challenge, as poor stereoselectivity and low functional-group compatibility stymie effective preparative routes. The use of enzymes has emerged as a versatile approach to prepare ncAAs, and nature's enzymes can be engineered to synthesize ncAAs more efficiently and expand the amino acid alphabet. In this tutorial review, we briefly outline different enzyme engineering strategies and then discuss examples where engineering has generated new 'ncAA synthases' for efficient, environmentally benign production of a wide and growing collection of valuable ncAAs. PMID- 30280155 TI - Reactive nano-patterns in triple structured bio-inspired honeycomb films as a clickable platform. AB - A hierarchically structured platform was obtained from directed self-assembly of a poly(styrene)-b-poly(4-vinylbenzylchloride) (PS-b-PVBC) block copolymer (BCP) during breath figure (BF) templating. The BF process using a water/ethanol atmosphere gave a unique double porosity in which hexagonally arranged micron sized pores were encircled by a secondary population of smaller, nano-sized pores. A third level of structuration was simultaneously introduced between the pores by BCP self-assembly to form out-of-the-plane nano-cylinders, offering a film with an unprecedented triple structure, which could be used as a reactive platform. Indeed the surface nano-domains of VBC were exploited as reactive nano patterns for site-specific chemical functionalization.

NCD-CC has a NCD domain, which recognizes the G-G mismatch in a CGG/CGG triad, and a cysteinylcystein (CC) moiety. Dimerization of NCD-CC through intermolecular disulfide bond formation was accelerated in the presence of CGG repeat DNA. PMID- 30280157 TI - Photoreduction of ferricytochrome c in the presence of potassium ferrocyanide. AB - Ferricytochrome c has been previously shown to photoreduce in the presence of ferrocyanide anions, but the process has been poorly understood. Here, we propose a kinetic model for this phenomenon and support it with resonance Raman measurements that show a clear dependence of photoreduction on the concentration of mixture components and laser power. Our data are consistent with the photoreduction process that is driven by photoexcitation of the heme followed by an electron transfer from the excited state of the heme macrocycle to the heme iron. Concomitantly, the hole in the heme ground state is filled with an electron transferred from a ferrocyanide ion residing in the heme pocket.

AB - Chiral-diamine catalyzed addition of ZnMe2 to PhC(O)CF2X (in dichloromethane at 30 degrees C) affords fluorinated alkyl tertiary alcohols in high yield (quantitative for X = H, F, Cl; 84% for X = CF3) and up to 99% ee. These conditions are similarly very efficient for other various ArC(O)CF3 molecules. A fine analysis of the results can be performed based on a double-cycle mechanism. PMID- 30280159 TI - An integrated micro-millifluidic processing system. AB - The development of integrated microfluidic systems/platforms concerns many fields. Current remarkable integrated systems based on stacking multi-layer polydimethylsiloxane (PDMS) require complicated fabrication and operation and still remain challenging. We propose a novel micro-millifluidic processing system (MPS) comprising three core modules: a motherboard, a control panel and microfluidic chips. Fluids are handled in sub-millichannels in a motherboard and functional operations occur in microchannels in microfluidic chips. A motherboard with versatile functional units for fluid handling was monolithically fabricated via multimaterial 3D printing, which avoids multi-layer structures, and the major disadvantage of current 3D printing, i.e. low resolution, has been overcome by integrating novel microfluidic chips based on our developed maskless lithography platform. Both numerical and experimental studies were conducted to validate our system. Potential applications such as droplet generation and distribution, microfluidic mixing and simple bacterial resistance tests have been demonstrated via our MPS. PMID- 30280160 TI - Multi-wavelength tailoring of a ZnGa2O4 nanosheet phosphor via defect engineering. AB - The multi-wavelength luminescence tailoring of an individual phosphor free of external dopants is of great interest and technologically important for practical applications. Using ZnGa2O4 nanosheets as a target phosphor, we demonstrate how to artificially control the luminescence wavelength centers and their emission intensities to simultaneously emit ultraviolet/blue, green and red light via a feasible defect engineering strategy. Simple high-temperature annealing of hydrothermally synthesized ZnGa2O4 nanosheets leads to the effective tunability of their emission process to present multi-wavelength luminescence due to the structural distortion and the formation of oxygen vacancies. Controlling the annealing temperature and time can further precisely modulate the wavelengths and their corresponding intensities. It is speculated that the migration of Ga into the [GaO4] tetrahedron and the O vacancy are responsible for the multi-wavelength luminescence of the ZnGa2O4 nanosheet phosphor. Finally, the tentative multi wavelength luminescence behavior of the ZnGa2O4 nanosheet phosphor via defect engineering is discussed based on a series of evidenced experimental observations of XRD, XPS, HRTEM and CL.

AB - Complex porous carbon nanostructures with homogeneously embedded nanoparticles and intricate architectures show promise as high-performance catalysts. Herein, we demonstrate a direct surfactant co-assembly approach for the fabrication of well-dispersed PdCu nanoparticles encapsulated in N-doped porous carbon with three-dimensional coralline structures. Owing to their porous features and unique frameworks, the PdxCuy@N-pC coralline-like nanostructures offer large surface areas, accessible active sites, and excellent nitrate electrocatalytic ability. The composite catalyst Pd4Cu4@N-pC exhibits outstanding catalytic performance with a high nitrate removal rate of ~95%, nitrogen selectivity of ~80%, and removal capacity of 22 000 mg N per g PdCu. More importantly, the present work opens up a broad horizon for architectures of nanoparticles confined in coralline like 3D porous carbon structures with superior performance and promising large scale applications. PMID- 30280164 TI - Modified surface states of NaGdF4:Yb3+/Tm3+ up-conversion nanoparticles via a post-chemical annealing process. AB - An amorphous layer acting as a quenching center at the surface of oleic acid capped NaGdF4:Yb3+/Tm3+ nanoparticles is observed directly, which can be reconstructed via a novel post-chemical annealing process. The amorphous phase of the surface layer of NaGdF4:Yb3+/Tm3+ nanoparticles gradually crystallizes as the post-chemical annealing temperature increases; meanwhile, the good dispersibility of the as-obtained nanoparticles is maintained. The reduction of surface defects and higher local symmetry of the crystal field environment around the doped rare earth ions contribute to drastically increased up-conversion (UC) emission intensity of the NaGdF4:Yb3+/Tm3+ nanoparticles. In particular, the blue emission of Tm3+ at 450 nm enhances 10-fold after the post-chemical annealing process at 250 degrees C compared with the counterpart without further surface-state treatments. The color gamut of well-crystallized NaGdF4:Yb3+/Tm3+ with a modified surface covers the blue to yellow region in CIE chromaticity coordinates via a non-steady-state UC process. The results indicate that the surface states of these UC nanoparticles can be feasibly improved via the post-chemical annealing process without encouraging agglomeration, which further optimizes their UC properties for practical applications.

AB - A method has been developed for extracting poppy alkaloids from oily matrices, specifically lipid residues associated with archaeological ceramics. The protocol has been applied to fresh and artificially aged poppyseed oil and to residue from a Late Bronze Age Cypriot juglet in the collections of the British Museum. The juglet is of a type that has been linked with ancient trade in opium due to its poppy-head shape and wide distribution; it is a rare example of an intact vessel with contents sealed inside. Bulk analysis of the residue by GC-EI-MS and pyGC-EI MS indicated a degraded plant oil and possible presence of papaverine. Analysis of the alkaloid extracts by HPLC-ESI-MS using both triple quadrupole and FTICR mass spectrometers detected the five primary opium alkaloids in fresh poppyseed oil and papaverine in most of the aged samples. Papaverine and thebaine were detected in the juglet residue, providing the first rigorous chemical evidence to support a link between this vessel type and opium, or at least poppies. The association of opium with oil raises new questions about the ancient purpose of the commodities within these vessels, and the low levels (ng g-1) of opiates detected in this unusually well-preserved residue shed doubt on the scope for their detection in more fragmentary ceramic remains (potsherds). Papaverine was found to exhibit challenging carryover behaviour in all the analytical methods used in this study. The phenomenon has not been reported before and should be considered in future analyses of this analyte in all application areas.

Their optical properties in five organic solvents have been measured, and the wavelength range of the maximum fluorescence emission peaks was from 469 nm to 509 nm. Besides, both of them exhibited high fluorescence quantum yields (0.79-0.96) in these organic solvents. The pH influenced optical properties tests indicated dyes 1a-b have strong fluorescence in sub acid (pH = 6.0) to alkaline environment (pH = 9.0). Their fluorescence quantum yields in neutral aqueous solution (pH = 7.0) were 0.82 (1a) and 0.78 (1b) respectively. In addition, dyes 1a-b exhibited stable fluorescence intensity in the presence of some metal cations and biomolecules in neutral solution (pH = 7.0). Subsequently, confocal microscopy imaging indicated that dyes 1a-b could be used as biomarkers for lipid droplets in living and fixed cells (I929 and HeLa cells).

AB - As a privileged chiral scaffold, cinchona alkaloid and its derivatives have reached remarkable success in catalytic asymmetric organic synthesis. In addition to the wide applications of point chirality control, Smith and co-workers recently discovered a quinidine-derived ammonium cation-catalyzed O-alkylation of tetralones, providing an effective approach for the synthesis of axially chiral biaryls. Using density functional theory (DFT) calculations, we studied the reaction mechanism and origins of enantioselectivity of this novel transformation. A stepwise strategy is adopted to ensure efficient and thorough exploration of the massive conformational space of transition state. Our computations suggested that enolate oxygen forms two hydrogen bonds with the chiral ammonium catalyst, and the non-covalent interactions between the cationic benzylic fragment and the methoxy group of enolate plays a critical role in determining the enantioselectivity. PMID- 30280169 TI - Temperature dependence of dynamic, tunnelling and kinetic isotope effects in formate dehydrogenase. AB - The origin of the catalytic power of enzymes has been a question of debate for a long time. In this regard, the possible contribution of protein dynamics in enzymatic catalysis has become one of the most controversial topics. In the present work, the hydride transfer step in the formate dehydrogenase (FDH EC 1.2.1.2) enzyme is studied by means of molecular dynamic (MD) simulations with quantum mechanics/molecular mechanics (QM/MM) potentials in order to explore any correlation between dynamics, tunnelling effects and the rate constant. The temperature dependence of the kinetic isotope effects (KIEs), which is one of the few tests that can be studied by experiments and simulations to shed light on this debate, has been computed and the results have been compared with previous experimental data. The classical mechanical free energy barrier and the number of recrossing trajectories seem to be temperature-independent while the quantum vibrational corrections and the tunnelling effects are slightly temperature dependent over the interval of 5-45 degrees C. The computed primary KIEs are in very good agreement with previous experimental data, being almost temperature independent within the standard deviations. The modest dependence on the temperature is due to just the quantum vibrational correction contribution. These results, together with the analysis of the evolution of the collective variables such as the electrostatic potential or the electric field created by the protein on the key atoms involved in the reaction, confirm that while the protein is well preorganised, some changes take place along the reaction that favour the hydride transfer and the product release. Coordinates defining these movements are, in fact, part of the real reaction coordinate.

AB - NMR spectra of Mg2+ ions in ionic liquids were recorded using a highly sensitive variant of NMR spectroscopy known as beta-NMR. The beta-NMR spectra of MgCl2 in EMIM-Ac and EMIM-DCA compare favourably with conventional NMR, and exhibit linewidths of ~3 ppm, allowing for discrimination of species with oxygen and nitrogen coordination. PMID- 30280171 TI - Bi2Se3 nanoplates for contrast-enhanced photoacoustic imaging at 1064 nm. AB - Photoacoustic (PA) imaging is a high-resolution biomedical imaging modality, which can be used to visualize biological tissues located beyond the limited penetration depth of existing optical imaging techniques. An optical wavelength of 1064 nm is of great interest in PA imaging due to low intrinsic absorption at this wavelength. Reduced absorption implies an increased depth of imaging, which enables several new clinical applications such as bladder imaging, gastrointestinal (GI) imaging, and sentinel lymph node (SLN) imaging. In addition, a 1064 nm Nd:YAG laser system enables a high power, cost-effective, and compact laser-based PA imaging system. However, at this wavelength, due to low intrinsic contrast, high absorption exogenous PA contrast agents are necessary for imaging. To this end, we present new Bi2Se3 nanoplates as PA contrast agents at 1064 nm wavelength for PA imaging. We successfully synthesized Bi2Se3 nanoplates and they exhibited relatively strong PA signals at 1064 nm. We confirmed the increased imaging depth of penetration by imaging the Bi2Se3 containing tube located 4.6 cm deep in biological tissues. We present in vivo PA imaging of the bladder, GI tract, and SLN in mice using a Bi2Se3 contrast agent establishing the clinical feasibility of these agents with a clinical photoacoustic/ultrasound imaging system. Our results confirm that Bi2Se3 nanoplates are promising PA contrast agents at 1064 nm that offer a high optical absorbance in the second NIR region providing a high contrast imaging and increased depth of penetration. PMID- 30280172 TI - Effects of thermal disorder on the electronic structure of halide perovskites: insights from MD simulations. AB - The effects of thermal disorder on the electronic properties of organic/inorganic halide perovskites were investigated using ab initio molecular dynamics simulations. It was generally found that band gap variations due to effects of thermal disorder are the largest in materials with the smallest lattice constant. The factors that may lead to departure from this trend include the degree of rotational and translational motion of the organic cation and the strength of its dipole. It was found that the contribution of the flexible organic part to the band gap variations is considerably smaller than the contribution of the inorganic part of the material. The results of our simulations indicate that band gap variations in halide perovskites fall within the range exhibited in inorganic semiconductors. PMID- 30280173 TI - Label-free imaging of epidermal growth factor receptor-induced response in single living cells. AB - Epidermal growth factor receptor (EGFR), which belongs to the second-largest protein family for cell signal transduction, plays crucial roles in homeostasis, cellular organized patterns and most human cancers. In EGFR-activated signaling networks, the detection of the spatial and temporal dynamics of cascades that encode the many cell fates is still a challenge. Here, we report real-time imaging of epidermal growth factor (EGF)-induced EGFR activation and its signaling cascade in single A431 cells using surface plasmon resonance (SPR) microscopy. A two-phase SPR response pattern was observed within 30 min after EGF treatment, including a positive SPR response that was related to the EGFR activated mass redistribution in the first 600 s, and a subsequent negative SPR signal caused by the morphological change of the cells. Furthermore, the inhibitor analysis verified that AG1478 inhibited the response from the whole the cell, whereas cytochalasin B strongly inhibited the response from the cell edge region. PMID- 30280174 TI - Characteristics of the excited triplet states of thiolated guanosine derivatives and singlet oxygen generation. AB - Thioguanine is sensitive to UVA light and generates singlet molecular oxygen (1O2*) when exposed to UVA. Three thioguanosine derivatives, 2',3',5'-tri-O acetyl-6-thioguanosine (ta6TGuo), 2',3',5'-tri-O-acetyl-8-thioguanosine (ta8TGuo), and 2',3',5'-tri-O-acetyl-6,8-dithioguanosine (taDTGuo) were explored photophysically and photochemically. Nanosecond transient absorption and time resolved near-infrared emission measurements were carried out to investigate the characteristics of their excited triplet states in acetonitrile solution. The quantum yield of intersystem crossing (PhiISC), the intrinsic decay rate constant (k0), the quenching rate constant by 3O2 (kq) and the self-quenching rate constant (kSQ) of their triplet states were all determined. From the precise analysis of the quantum yield of 1O2* generation (PhiDelta) against the concentration of dissolved molecular oxygen, the fraction of the triplet states quenched by dissolved oxygen which gives rise to 1O2* formation (SDelta) was successfully obtained with high accuracy. The PhiDelta values at low oxygen concentrations reveal that these thioguanosines, particularly taDTGuo, can still effectively generate 1O2* at low molecular oxygen concentrations like carcinomatous microenvironments. These findings indicate that taDTGuo would perform well as a potential agent for photo-induced cancer therapies.

AB - A boratriazine ligand, which incorporates attractive features from both bodipy and terpy, has been used to synthesize [Fe2II(MU1,1-N3)2(Py2F2BTA)2(N3)2] (1) and [Co2II(MU1,1-N3)2(Py2F2BTA)2(N3)2] (2). Both 1 and 2 feature a double end-on azido bridging motif, which promotes ferromagnetic interactions between the metal centres. Indeed, 1 represents the first report of a dinuclear FeII complex with this bridging mode exhibiting J = 5.7(9) cm-1 and D = -6.0(4) cm-1, while the isostructural Co analogue shows J = 7.1(9) cm-1 and D = 17.3(9) cm-1. PMID- 30280176 TI - Controlling stacking order and charge transport in pi-stacks of aromatic molecules based on surface assembly. AB - Here, we report a facile procedure based on surface self-assembly for controlling the pi-pi stacking order and relevant rectified charge transport properties in stacks of aromatic molecules on a single-molecule scale. A high rectification ratio of 10 was achieved and the rectification direction was uniquely determined by the controlled stacking order of the aromatic molecules on the graphene layers of HOPG. PMID- 30280177 TI - A sulphur and uranium fiesta! Synthesis, structure, and characterization of neutral terminal uranium(vi) monosulphide, uranium(vi) eta2-disulphide, and uranium(iv) phosphine sulphide complexes. AB - Three new uranium species (C5Me5)2U([double bond, length as m-dash]N-2,6-iPr2 C6H3)([double bond, length as m-dash]S), (C5Me5)2U([double bond, length as m dash]N-2,6-iPr2-C6H3)(eta2-S2), and (C5Me5)2U([double bond, length as m-dash]N 2,6-iPr2-C6H3)(S[double bond, length as m-dash]PMe3) were synthesized and fully characterized by a combination of NMR, IR, and UV/vis-NIR spectroscopies, elemental analysis, and cyclic voltammetry. The solid state structures of (C5Me5)2U([double bond, length as m-dash]N-2,6-iPr2-C6H3)([double bond, length as m-dash]S) and (C5Me5)2U([double bond, length as m-dash]N-2,6-iPr2-C6H3)(eta2-S2) were also determined. The compound (C5Me5)2U([double bond, length as m-dash]N-2,6 iPr2-C6H3)([double bond, length as m-dash]S) is the first neutral uranium complex with a terminal sulphido ligand, and (C5Me5)2U([double bond, length as m-dash]N 2,6-iPr2-C6H3)(S[double bond, length as m-dash]PMe3) is the first uranium compound with a coordinated phosphine sulphide ligand. The phosphine sulphide adduct, (C5Me5)2U([double bond, length as m-dash]N-2,6-iPr2-C6H3)(S[double bond, length as m-dash]PMe3), can be synthesized either by reaction of the uranium(iv) complex (C5Me5)2U([double bond, length as m-dash]N-2,6-iPr2-C6H3)(thf) with S[double bond, length as m-dash]PMe3 or by the reaction of the uranium(vi) terminal sulphido complex (C5Me5)2U([double bond, length as m-dash]N-2,6-iPr2 C6H3)([double bond, length as m-dash]S) with PMe3.

The alkylpalladium intermediate coupled with the diazo compound, generating the second alkylpalladium species bearing two beta-H, which generated a terminal alkene as the major products in the anti-Zaitsev way via the highly regioselective beta-H elimination. It provided a new way to synthesize tetrahydropyridine derivatives bearing a terminal alkene. PMID- 30280179 TI - Single-compartment hydrogen peroxide fuel cells with poly(3,4 ethylenedioxythiophene) cathodes. AB - Single-compartment hydrogen peroxide fuel cells have recently emerged as a promising energy conversion platform since H2O2 is a high energy-density liquid that functions as both fuel and oxidizer. Finding suitable electrocatalysts is challenging since most metallic electrodes also catalyze the disproportionation reaction of H2O2 into H2O and O2, representing a significant loss mechanism in peroxide fuel cells. Herein we demonstrate that the conducting polymer poly(3,4 ethylenedioxythiophene), PEDOT, is a versatile electrocatalyst for peroxide fuel cells without generating losses due to disproportionation. We find that PEDOT is a cathodic catalyst for reduction of peroxide to water, performing at a level on par with the best reported inorganic catalysts. Using PEDOT as the cathode and nickel as the anode material, open circuit potentials in the range of 0.5-0.6 V are possible, with power densities of 0.20-0.30 mW cm-2. We provide evidence to understand mechanistically how PEDOT functions as a catalyst for hydrogen peroxide reduction to water. The result of our efforts is a scalable hydrogen peroxide fuel cell cathode, which serves to demonstrate also the capabilities of organic semiconducting materials as electrocatalysts.

AB - We proposed a mechanism to induce strong magnetism of up to 10.92 emu g-1 in hexagonal-phase arsenene nanoribbon (AsNR) from the perspective of edge quantum entrapment. Consistency between bond-order-length-strength correlation (BOLS) theory and density functional theory (DFT) calculations verified that: (i) the edge bond contraction of 9.54% deepened the edge potential well of AsNR, (ii) a net charge of 0.06 e- transferred from the inner region to the edge; and (iii) the edge quantum well polarized the unpaired electron and the net spin (antiferromagnetic or ferromagnetic depending on the width) is localized at the zigzag edge. The finding sheds a light on applications of AsNR in magnetic storage devices. PMID- 30280181 TI - Movement of palladium nanoparticles in hollow graphitised nanofibres: the role of migration and coalescence in nanocatalyst sintering during the Suzuki-Miyaura reaction. AB - The evolution of individual palladium nanoparticle (PdNP) catalysts in graphitised nanofibres (GNF) in the liquid-phase Suzuki-Miyaura (SM) reaction has been appraised. The combination of identical location-transmission electron microscopy (IL-TEM) and a nano test tube approach allowed spatiotemporally continuous observations at the single nanoparticle level, revealing that migration and coalescence is the most significant pathway to coarsening of the nanocatalyst, rather than Ostwald ripening. IL-TEM gave unprecedented levels of detail regarding the movement of PdNP on carbon surfaces at the nanoscale, including size-dependent migration and directional movement, opening horizons for the optimisation of future catalysts through surface morphology design. PMID- 30280182 TI - The role of focal adhesion kinase in transforming growth factor-beta2 induced migration of human lens epithelial cells. AB - The migration of lens epithelial cells towards the posterior capsule is a key event in the development of posterior capsule opacification (PCO). Accumulating evidence has described crosstalk between growth factors and adhesive signaling pathways in wound healing and cell migration. The aim of the present study was to elucidate an aberrant transforming growth factor (TGF)-beta2 signaling pathway that regulated the migration of lens epithelial cells in the pathological context of PCO. The expression of fibronectin, focal adhesion kinase (FAK) and phosphorylated (p)-FAK in HLE-B3 cells following TGF-beta2 treatment was determined by western blot analysis and the expression of integrin alpha5beta1 was detected by flow cytometry. Cell migration capacity was measured by wound healing and Transwell assays in the presence of 1,2,4,5-tetraaminobenzene tetrahydrochloride, a selective FAK inhibitor, fibronectin small interfering RNA interference, arginylglycylaspartic acid peptides or alpha5beta1-integrin neutralizing antibodies. The 1,2,4,5-tetraaminobenzene tetrahydrochloride was administered daily to 16 rabbits following cataract surgery. Fibronectin and TGF beta expression were increased in the PCO group, demonstrated by immunofluorescence assays. PCO grading was conducted by slit-lamp biomicroscopy and evaluation of posterior capsule opacification software. It was observed that TGF-beta2 promoted HLE-B3 cell migration and upregulated fibronectin expression, which was followed by an increased phosphorylation of FAK. In addition, TGF-beta2 treatment and fibronectin surface coating significantly increased cell migration and FAK activation, which was inhibited by disrupting fibronectin-integrin alpha5beta1 interaction with the arginylglycylaspartic acid peptide, alpha5beta1 integrin neutralizing antibody or fibronectin depletion. Finally, suppression of FAK signaling by its inhibitor significantly decreased cell migration in vitro and attenuated PCO development in vivo. In summary, TGF-beta2 was indicated to promote the migration of lens epithelial cells through the TGF beta2/fibronectin/integrin/FAK axis. Inhibition of FAK activity decreased TGF beta2-mediated cell migration in vitro and improved the symptoms of PCO in a rabbit model. PMID- 30280183 TI - Protective effect of luteolin on skin ischemia-reperfusion injury through an AKT dependent mechanism. AB - Cutaneous ischemia-reperfusion (I/R) injury is one of the most crucial problems in flap surgery, which affects the survival of the skin flap and patient prognosis, luteolin, a plant derived flavonoid, has previously been shown to exert a variety of beneficial effects for reducing I/R injury in several organs. The aim of the present study was to evaluate the anti-inflammatory and anti oxidative stress effects of luteolin on cutaneous I/R injury. The in vitro study were performed using a permanent human immortalized epidermal keratinocyte cell line (HaCaT), cells were cultured in the presence of luteolin and were then treated with hydrogen peroxide, the cell viability, mitochondrial membrane potential and the cell survival/apoptosis related signaling pathway activation were assessed to investigate the cytoprotective effects of luteolin. For in vivo experiments, skin flap I/R injury animal model was established in Sprague-Dawley rats, by measuring the area of flap survival, analyzing the expression of pro inflammatory cytokine and evaluation of the histological changes in the skin tissue, the protective effects of luteolin on skin I/R injury were investigated. The function of protein kinase B (AKT) and heme oxygenase-1 (HO-1) activation on luteolin mediated I/R injury protection was assessed by administration of phosphoinositide-3-kinase/AKT inhibitor LY294002 and HO-1 inhibitor ZNPP. The results showed that luteolin treatment significantly increased the viability of HaCaT cells upon exposure to hydrogen peroxide, and the administration of luteolin in vivo significantly improved skin flap survival in the I/R injury rat model. The mechanisms underlying these beneficial effects included increased phosphoinositide-3-kinase/protein kinase B activation, improved expression of antioxidant enzyme, and scavenging the cytotoxic effects of reactive oxygen species (ROS). Taken together, the results suggested that luteolin preconditioning yielded significant protection against cutaneous I/R injury by protecting skin keratinocytes from ROS-induced damage. PMID- 30280185 TI - Suppressing cell growth and inducing apoptosis by inhibiting miR-23a-5p in human bladder cancer. AB - MicroRNAs (miRNAs) are a class of non-coding RNAs, which are important in the initiation and progression of cancer. miRNA-23a-5p (miR-23a-5p) is a novel miRNA, which promotes cell growth and survival in several types of cancer. The aim of the present study was to investigate the expression and functional significance of miR-23a-5p in bladder cancer. Microchip assays have shown that miR-23a-5p is significantly upregulated in human bladder cancer. In the present study, it was found that miR-23a-5p was upregulated in bladder cancer tissues, compared with paired normal urothelial tissues by reverse transcription-quantitative polymerase chain reaction. The impact of miR-23a-5p on cell proliferation, cell migration and apoptosis was determined by a 3-(4,5-dimethylthi-azol-2-yl)-2,5 diphenyltetrazolium bromide assay, wound scratch assay and flow cytometry. The inhibition of cell proliferation and induction of apoptosis were also observed in miR-23a-5p inhibitor-transfected T24 and SW780 human bladder cancer cells. These data suggested that miR-23a-5p has an oncogenic role and may be a therapeutic target for bladder cancer. PMID- 30280187 TI - Mangiferin: An effective therapeutic agent against several disorders (Review). AB - Mangiferin (1,3,6,7-tetrahydroxyxanthone-C2-beta-D-glucoside) is a bioactive ingredient predominantly isolated from the mango tree, with potent antioxidant activity and multifactorial pharmacological effects, including antidiabetic, antitumor, lipometabolism regulating, cardioprotective, anti-hyperuricemic, neuroprotective, antioxidant, anti-inflammatory, antipyretic, analgesic, antibacterial, antiviral and immunomodulatory effects. Therefore, it possesses several health-endorsing properties and is a promising candidate for further research and development. However, low solubility, mucosal permeability and bioavailability restrict the development of mangiferin as a clinical therapeutic, and chemical and physical modification is required to expand its application. This review comprehensively analyzed and collectively summarized the primary pharmacological actions of mangiferin that have been demonstrated in the literature, to support the potential future development of mangiferin as a novel therapeutic drug. PMID- 30280184 TI - Maintenance of intracellular Ca2+ basal concentration in airway smooth muscle (Review). AB - In airway smooth muscle, the intracellular basal Ca2+ concentration [b(Ca2+)i] must be tightly regulated by several mechanisms in order to maintain a proper airway patency. The b[Ca2+]i is efficiently regulated by sarcoplasmic reticulum Ca2+-ATPase 2b, plasma membrane Ca2+-ATPase 1 or 4 and by the Na+/Ca2+ exchanger. Membranal Ca2+ channels, including the L-type voltage dependent Ca2+ channel (L VDCC), T-type voltage dependent Ca2+ channel (T-VDCC) and transient receptor potential canonical 3 (TRPC3), appear to be constitutively active under basal conditions via the action of different signaling pathways, and are responsible for Ca2+ influx to maintain b[Ca2+]i. The two types of voltage-dependent Ca2+ channels (L- and T-type) are modulated by phosphorylation processes mediated by mitogen-activated protein kinase kinase (MEK) and extracellular-signal-regulated kinase 1 and 2 (ERK1/2). The MEK/ERK signaling pathway can be activated by G protein-coupled receptors through the alphaq subunit when the endogenous ligand (i.e., acetylcholine, histamine, leukotrienes, etc.) is present under basal conditions. It may also be stimulated when receptor tyrosine kinases are occupied by the appropriate ligand (cytokines, growth factors, etc.). ERK1/2 phosphorylates L-VDCC on Ser496 of the beta2 subunit and Ser1928 of the alpha1 subunit, decreasing or increasing the channel activity, respectively, and enabling it to switch between an open and closed state. T-VDCC is also probably phosphorylated by ERK1/2, although further research is required to identify the phosphorylation sites. TRPC3 is directly activated by diacylglycerol produced by phospholipase C (PLCbeta or gamma). Constitutive inositol 1,4,5-trisphosphate production induces the release of Ca2+ from the sarcoplasmic reticulum through inositol triphosphate receptor 1. This ion induces Ca2+-induced Ca2+ release through the ryanodine receptor 2 (designated as Ca2+ 'sparks'). Therefore, several Ca2+ handling mechanisms are finely tuned to regulate basal intracellular Ca2+ concentrations. It is conceivable that alterations in any of these processes may render airway smooth muscle susceptible to develop hyperresponsiveness that is observed in ailments such as asthma. PMID- 30280186 TI - Long non-coding RNA C5orf66-AS1 prevents oral squamous cell carcinoma through inhibiting cell growth and metastasis. AB - Oral squamous cell carcinoma (OSCC) is a major cancer type in the head and neck region. Recent studies have reported a marked rise in the incidence of OSCC. The present study was performed to better understand the roles that long non-coding RNAs (lncRNAs) serve in OSCC carcinogenesis. The levels of the lncRNA C5orf66 antisense RNA 1 (C5orf66-AS1) and of cytochrome c1 (CYC1) in OSCC tissues and cells were measured through reverse transcription-quantitative polymerase chain reaction. In addition, the levels of associated proteins were analyzed by western blotting, while MTT assay was used to detect the cell proliferation ability. Wound healing and transwell assays were also used to detect the migration and invasion abilities of OSCC cells in the experimental groups, while flow cytometry was applied to analyze cell apoptosis. The findings revealed that the expression of lncRNA C5orf66-AS1 in OSCC tissues and cells was significantly decreased. Overexpression of lncRNA C5orf66-AS1 significantly inhibited the proliferation, invasion and migration ability of OSCC cells, and promoted cell apoptosis, while lncRNA C5orf66-AS1 downregulation presented the opposite effects. In addition, it was observed that CYC1 was upregulated in OSCC tissues and cells, and was negatively regulated by lncRNA C5orf66-AS1. Notably, CYC1 silencing markedly eliminated the effects of lncRNA C5orf66-AS1 downregulation on OSCC cells. Taken together, these findings indicated that lncRNA C5orf66-AS1 may prevent OSCC progression by inhibiting OSCC cell growth and metastasis via the regulation of CYC1 expression. PMID- 30280188 TI - Ketamine destabilizes growth of dendritic spines in developing hippocampal neurons in vitro via a Rho-dependent mechanism. AB - The safety of anesthetics on the developing brain has caused concern. Ketamine, an N-methyl-D-aspartate receptor antagonist, is widely used as a general pediatric anesthetic. Recent studies suggested that ketamine alters the plasticity of dendritic spines in the developing brain and may be an important contributing factor to learning and cognitive impairment. However, the underlying molecular mechanism remains poorly understood. Therefore, the aim of the present study was to investigate the effect of ketamine on the plasticity of dendritic spines in cultured hippocampal neurons and the potential underlying mechanisms. After 5 days in vitro, rat hippocampal neurons were exposed to different concentrations (100, 300 and 500 uM) of ketamine for 6 h. Ketamine decreased the number and length of dendritic spines in a dose-dependent manner. Ketamine at a concentration of 300 uM caused an upregulation of transforming protein RhoA (RhoA) and Rho-associated kinase (ROCK) protein. These effects were inhibited by the ROCK inhibitor Y27632. These results suggested that ketamine induces loss and shortening of dendritic spines in hippocampal neurons via activation of the RhoA/ROCK signaling pathway. PMID- 30280189 TI - MrgX2-mediated internalization of LL-37 and degranulation of human LAD2 mast cells. AB - LL-37 is the sole antimicrobial peptide of human cathelicidin comprising 37 amino acids, which is expressed mainly in epithelial cells and neutrophils, and activates mast cells. In the present study, in order to elucidate the mechanism of mast cell activation by LL-37, the associations between the internalization of LL-37 and Mas-related gene X2 (MrgX2)-mediated mast cell activation (degranulation) was investigated using the human mast cell line, LAD2. LL-37 was rapidly internalized into the cells, and induced degranulation, as assessed by the extracellular release of beta-hexosaminidase. Pertussis toxin, a G-protein inhibitor, significantly suppressed the internalization of LL-37 and the degranulation of LAD2 cells. Furthermore, small interfering (si)-RNA-mediated knockdown of MrgX2, a putative G protein-coupled receptor for LL-37, inhibited the internalization of LL-37 and degranulation of LAD2 cells. Notably, LL-37 internalization was enhanced by the stable expression of MrgX2 in HMC-1 and 293 cells. In addition, the internalized LL-37 mainly colocalized with MrgX2 in the perinuclear region of LAD2 cells. Furthermore, neuraminidase treatment, which removes negatively charged sialic acid from the cell surface, markedly reduced the internalization of LL-37 and degranulation of LAD2 cells, and clathrin mediated endocytosis inhibitors (dynasore and chlorpromazine) inhibited the internalization and degranulation of LAD2 cells. Taken together, these observations indicated that LL-37 may bind the negatively charged cell surface molecules, rapidly internalize into the cells via clathrin-mediated endocytosis and interact with MrgX2 to activate mast cells (LAD2 cells). PMID- 30280190 TI - Secretogranin III may be an indicator of paraquat-induced astrocyte activation and affects the recruitment of BDNF during this process. AB - Astrocyte activation has been described as a multi-stage defensive response, which is characterized by the morphological alteration of astrocytes and the overexpression of intermediate filament proteins. However, the functional mechanism of the secretion system in activated astroglia remains unclear. It has previously been demonstrated that secretogranin II, a member of the granin family, may be involved in the sorting and expression of inflammatory factors and excitatory neurotransmitters in paraquat (PQ)-induced astroglial activation. Secretogranin III (SCG3) has been reported to represent an important component of the regulated secretory pathway in neuroendocrine cells; however, its role as an anchor protein of dense-core vesicles in astrocytes remains to be elucidated. In the present study, a PQ-activated U118MG astrocytoma cell model established in our previous study was used to investigate the effects of SCG3. The results revealed that SCG3 was highly expressed and subsequently released from cells in response to PQ. Inhibition of SCG3 expression via transfection with small interfering RNA partially restored astrocyte morphology, but did not affect the expression of astrocytic factors. Further studies investigating the association between SCG3 and other cellular factors were conducted, in order to determine the expression levels and subcellular localization of these proteins. Neurotrophins and inflammatory factors exhibited an increase in characteristic expression patterns, paralleling the alterations in SCG3 expression. The results further demonstrated that brain-derived neurotrophic factor partially colocalized with SCG3-positive vesicles; however, the localization of interleukin-6 was not affected. In conclusion, SCG3 may be involved in PQ-induced astrocyte activation via regulation of the expression and selective recruitment of cellular factors, thus suggesting that SCG3 may represent an indicator of astrocyte activation. PMID- 30280191 TI - Overexpression of small ubiquitin-like modifier 2 ameliorates high glucose induced reductions in cardiomyocyte proliferation via the transforming growth factor-beta/Smad pathway. AB - Hyperglycemia may induce diabetic cardiomyopathy (DC). In the current study, the mechanism underlying the alleviation of high glucose (HG)-induced impairments in the proliferation of H9c2 embryo cardiomyocyte proliferation by small ubiquitin like modifier 2 (SUMO2) overexpression was investigated. H9c2 cell morphology was identified as classical long shuttle type by optical microscopy. The viability of HG-injured H9c2 cells was evaluated by a Cell Counting Kit-8 assay and the results indicated that viability was inhibited in a dose-dependent (5.6, 10, 20 and 30 mmol/l) and time-dependent (6, 12 and 24 h) manner. H9c2 cells treated with 20 mmol/l HG for 24 h were selected for subsequent experiments due to the extent of injury caused at a low density. Flow cytometry was conducted to confirm cell cycle arrest between G1/S phases and apoptosis promotion in HG-injured H9c2 cells, and the subsequent alleviating effect of SUMO2 overexpression on these HG induced effects. Reverse transcription-quantitative polymerase chain reaction (RT qPCR) and western blot analysis were performed to detect mRNA and protein expression levels of cell cycle-and apoptosis-associated factors. The results indicated that the expression ofthe cell cycle-associated factors CyclinA2 and C Myc was upregulated, and cyclin-dependent kinase inhibitor 1a was downregulated. The expression of the apoptosis-associated factor Bcl-2 was upregulated, while Bcl-2-associated X and caspase-3 expression was downregulated, by SUMO2 overexpression. Furthermore, the effect of SUMO2 overexpression on the transforming growth factor (TGF)-beta/Smad pathway was also determined using RT qPCR and western blot analysis. The results indicated the mRNA and protein levels of TGF-beta1 and Smad3 in HG-injured H9c2 cells were significantly decreased following SUMO2 overexpression. Thus, the results demonstrated that overexpression of SUMO2 may alleviate H9c2 cardiomyocyte cell cycle arrest and apoptosis promotion induced by HG via regulation of cell cycle- and apoptosis associated factors, as well as inhibition of the TGF-beta/Smad pathway. These results may therefore provide a novel strategy for the protection of cardiomyocytes and may aid the diagnosis and prognosis of patients with DC. PMID- 30280192 TI - Whole exome sequencing identification of a novel insertion mutation in the phospholipase C epsilon-1 gene in a family with steroid resistant inherited nephrotic syndrome. AB - Nephrotic syndrome (NS) represents a heterogeneous group of kidney disorders characterized by excessive proteinuria, hypoalbuminemia and edema. Defects in the filtration barrier of the glomeruli results in the development of NS. The genetic cause of NS remains to be fully elucidated. However, previous studies based on positional cloning of genes mutated in NS have provided limited insight into the pathogenesis of this disease. Mutations in phospholipase C epsilon-1 (PLCE1) have been reported as a cause of early onset NS characterized by histology of diffuse mesangial sclerosis. In the present study, the underlying cause of NS in a consanguineous family was identified. Clinical and molecular aspects of a consanguineous Saudi family comprised of five individuals with steroid resistant NS were examined. Seven healthy individuals from the same family were also studied. Whole exome sequencing (WES) was performed to detect the genetic defect underlying NS. WES identified a homozygous novel insertion mutation (c.6272_6273insT) in the PLCE1 gene. Pedigree and segregation analysis confirmed an autosomal recessive inheritance pattern. This mutation may result in a bi allelic loss of the C-terminal Ras-associating domain in PLCE1 that results in NS. The present study expanded the mutational spectrum of PLCE1 in NS. In addition, the present study provided further evidence that supports the important involvement of PLCE1 in the physiological function of the glomerular filtration barrier. PMID- 30280193 TI - Evidence and perspective for the role of the NLRP3 inflammasome signaling pathway in ischemic stroke and its therapeutic potential (Review). AB - Ischemic stroke is one of the main causes of death and disablement globally. The NLR family pyrin domain containing 3 (NLRP3) inflammasome is established as a sensor of detecting cellular damage and modulating inflammatory responses to injury during the progress of ischemic stroke. Inhibiting or blocking the NLRP3 inflammasome at different stages, including expression, assembly, and secretion, may have great promise to improve the neurological deficits during ischemic stroke. The current review provides a comprehensive summary of the current understanding in the literature of the molecular structure, expression, and assembly of the NLRP3 inflammasome, and highlights its potential as a novel therapeutic target for ischemic stroke. PMID- 30280194 TI - Compound pathogenic mutation in the USH2A gene in Chinese RP families detected by whole-exome sequencing. AB - Retinitis pigmentosa (RP) is a common form of inherited retinal degeneration that causes progressive loss of vision or adult blindness, characterized by the impairment of rod and cone photoreceptors. At present, mutations in >60 pathogenic genes have been confirmed to cause RP. The predominant modes of inheritance are autosomal dominant, autosomal recessive and X-linked. In addition, other modes of inheritance, including digenic or mitochondrial inheritance, have been reported. In previous decades, with the development of sequencing techniques, significant advances in identifying novel RP pathogenic genes and screening mutations have been made. In the present study, whole-exome sequencing was performed on samples from two Chinese pedigrees diagnosed with RP. A compound heterozygous mutation in the gene usherin 2A (USH2A; c.6,485+5G>A/c.11,156G>A) and a heterozygous X-linked mutation in the gene retinitis pigmentosa 2 (RP2) ARL3 GTPase-activating protein (RP2; c.358C>T) were identified by Sanger sequencing and co-segregation analysis, of which the pathogenic mutation (c.6,485+5G>A) in USH2A has not been previously reported among Chinese patients. The findings of the present study may expand on current knowledge of RP among the Chinese population, providing essential assistance in the molecular diagnosis and screening of RP, and promoting further investigation of the pathogenesis of RP. PMID- 30280196 TI - MicroRNA-944 targets vascular endothelial growth factor to inhibit cell proliferation and invasion in osteosarcoma. AB - Emerging evidence has demonstrated that the dysregulation of microRNA (miRNA/miR) serves a crucial role in the tumorigenesis and tumor development of osteosarcoma (OS), primarily by affecting various pathological behaviors. Therefore, better knowledge of miRNA in OS may provide novel insights into the pathogenesis of OS, and may facilitate the development of promising therapeutics for patients with this disease. MiRNA-944 is frequently dysregulated in human cancers. However, the expression levels, functions and underlying mechanisms of miR-944 in OS remain largely elusive. In the present study, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was performed to detect miR-944 expression in OS tissues and cell lines. The regulatory influence of miR-944 in OS proliferation and invasion was determined with MTT and Transwell invasion assays. In addition, the mechanisms underlying the action of miR-944 in OS cells were elucidated through a series of experiments, including bioinformatics analysis, luciferase reporter assay, RT-qPCR and western blot analysis. Spearman's correlation analysis was utilized to examine the relationship between miR-944 and VEGF expression levels, and rescue experiments were applied to further verify whether VEGF mediates the role of miR-944 in OS. The results demonstrated that miR-944 was downregulated in cancer tissues and cell lines. Furthermore, exogenous miR-944 expression inhibited cell proliferation and invasion in OS in vitro. Vascular endothelial growth factor (VEGF) was identified as a direct target of miR-944 in OS and was overexpressed in cancer tissues. VEGF expression was inversely correlated with miR-944 expression in cancer tissues. Rescue experiments demonstrated that overexpression of VEGF partially prevented the miR 944-induced inhibition of OS cell proliferation and invasion. These results suggested that miR-944 may serve a tumor suppressive role in OS by directly targeting VEGF. Therefore, miR-944 may be a promising target in the treatment of OS. PMID- 30280195 TI - Salmonella-induced miR-155 enhances necroptotic death in macrophage cells via targeting RIP1/3. AB - Salmonella enterica serovar Typhimurium (hereafter referred to as Salmonella), a virulent pathogen, is known to induce host-cell death. Using reverse transcription-quantitative polymerase chain reaction, a 28-fold increase of microRNA (miR)-155 expression in RAW 264.7 macrophages was observed following infection with Salmonella for 24 h. This miR-155 upregulation increased macrophage cell death by up to 40% in 48 h following infection. Western blot analysis revealed that receptor interacting protein 1 (RIP1) and 3 (RIP3) were increased at 18 h following miR-155 transfection to macrophages, similar to Salmonella infection. In addition, inhibition of RIP1 by pre-incubating macrophages with necrostatin-1, a RIP1 specific inhibitor, increased the viability of Salmonella-infected cells and miR-155-transfected cells by up to 20%. The cleavage of poly (adenosine diphosphate-ribose) polymerase-1 (PARP-1) was also enhanced by miR-155 induction upon Salmonella infection. Therefore, it was suggested that RIP1/3-induced necroptosis and PARP-1-mediated necrosis caused by miR-155 induction may represent distinct routes of programmed necrotic cell death of Salmonella-infected macrophages. PMID- 30280197 TI - An RGD small-molecule integrin antagonist induces detachment-mediated anoikis in glioma cancer stem cells. AB - The malignancy of glioblastoma (GB) is primarily due to the ability of glioma cancer stem cells (GSC) to disseminate into surrounding brain tissues, despite surgery and chemotherapy, and to form new tumoral masses. Members of the RGD binding integrin family, which recognize the arginine-glycine-aspartic acid (RGD) sequence present in components of the extracellular matrix, and which serve a crucial function in the dissemination of GCS, are overexpressed in GB. Small molecule integrin antagonists (SMIAs) designed to recognize RGD-integrins may therefore be an effective tool for decreasing GB infiltration and recurrence. In the present study, in vitro pro-apoptotic and infiltrative effects elicited by the SMIA 1a-RGD in human GSC were investigated. Reverse transcription quantitative polymerase chain reaction analysis revealed that, compared with normal human astrocytes, GSC grown on laminin-coated dishes overexpressed stemness markers as well as alphavbeta3 and alphavbeta5 integrins. In addition, dissociated GSC were identified to exhibit tumorigenic capacity when injected into immunodeficient mice. Using annexin/fluorescence-activated cell sorting analysis and ELISA nucleosome assays, it was identified that treatment of GSC with 25 uM 1a-RGD for 48 h elicited detachment-dependent anoikis not accompanied by necrosis-dependent cell death. A colorimetric proliferation assay indicated that 1a-RGD did not affect cell viability, but that, instead, it markedly inhibited GSC migration as assessed using a Transwell assay. Western blot experiments revealed a decrease in focal adhesion kinase and protein kinase B phosphorylation with a concomitant increase in caspase-9 and -3/7 activity following 1a-RGD treatment, suggesting that the pro-anoikis effects of 1a-RGD may be mediated by these molecular mechanisms. Western blot analysis revealed no changes in specific markers of autophagy, suggesting further that 1a-RGD-induced cell death is primarily sustained by anoikis-associated mechanisms. In conclusion, the results of the present study indicate that SMIA have potential as a therapeutic tool for decreasing GSC dissemination. PMID- 30280198 TI - Profiling cytochrome P450 family 4 gene expression in human hepatocellular carcinoma. AB - Cytochrome P450 family 4 (CYP4) enzymes are known as microsomal omega (omega) hydroxylases that metabolize fatty acids, eicosanoids, vitamin D and carcinogens. Thus, CYP4 enzymes may influence tumor development and progression. The aim of the present study was to evaluate the CYP4 expression profile in hepatocellular carcinoma (HCC) and its clinical relevance. The present study obtained CYP4 mRNA expression data for 377 HCC cases from The Cancer Genome Atlas cohort and performed Kaplan-Meier survival, Gene Ontology functional enrichment, and gene set enrichment analysis (GSEA). In addition, the level of CYP4F2 protein expression was evaluated in matched pairs of HCC and non-tumor tissue samples and the results were correlated with the clinicopathological characteristics of HCC (n=113). HCC survival analyses indicated better overall survival in patients with high CYP4F2, CYP4F12 and CYP4V2 mRNA expression levels; the results for histological grade and Tumor-Node-Metastasis stage supported these results. GSEA revealed high levels of CYP4F2, CYP4F12 and CYP4V2 mRNA expression to be negatively correlated with the expression of cell cycle-associated genes. CYP4F2 protein expression was higher in non-neoplastic liver tissue than in HCC tissue and positively correlated with favorable pathological tumor stage (I vs. II-IV; P=0.022) and was a good independent prognostic factor for overall survival (P=0.004). These results demonstrate that the expression levels of the genes CYP4F2, CYP4F12 and CYPV2 are favorable prognostic factors in HCC and suggest the potential predictive diagnostic and prognostic roles of CYP4F2, CYP4F12 and CYPV2 gene expression in HCC. PMID- 30280199 TI - BML-111 suppresses TGF-beta1-induced lung fibroblast activation in vitro and decreases experimental pulmonary fibrosis in vivo. AB - Pulmonary fibrosis is an aggressive end-stage disease. Transforming growth factor beta1 (TGF-beta1) mediates lung fibroblast activation and is essential for the progress of pulmonary fibrosis. BML-111, a lipoxinA4 (LXA4) receptor (ALX) agonist, has been reported to possess anti-fibrotic properties. The present study aimed to elucidate whether BML-111 inhibits TGF-beta1-induced mouse embryo lung fibroblast (NIH3T3 cell line) activation in vitro and bleomycin (BLM)-induced pulmonary fibrosis in vivo. In vitro experiments demonstrated that BML-111 treatment inhibits TGF-beta1-induced NIH3T3 cell viability and the expression of smooth muscle alpha actin (alpha-SMA), fibronectin and total collagen. Furthermore, this suppressive effect was associated with mothers against decapentaplegic homolog (Smad)2/3, extracellular signal-regulated kinase (ERK) and Akt phosphorylation interference. In vivo experiments revealed that BML-111 treatment markedly improved survival rate and ameliorated the destruction of lung tissue structure. It also reduced interleukin-1beta (IL-1beta), tumor necrosis factor-alpha (TNF-alpha) and TGF-beta1 expression in the BLM intratracheal mouse model. In addition, the expression ofalpha-SMA and extracellular matrix (ECM) deposition (total collagen, hydroxyproline and fibronectin) were also suppressed following BML-111 treatment. However, BOC-2, an antagonist of ALX, partially weakened the effects of BML-111. In conclusion, these results indicated that BML 111 inhibits TGF-beta1-induced fibroblasts activation and alleviates BLM-induced pulmonary fibrosis. Therefore, BML-111 may be used as a potential therapeutic agent for pulmonary fibrosis treatment. PMID- 30280201 TI - Metastatic cancer cells compensate for low energy supplies in hostile microenvironments with bioenergetic adaptation and metabolic reprogramming. AB - Metastasis accounts for the majority of cancer-related mortalities, and the complex processes of metastasis remain the least understood aspect of cancer biology. Metabolic reprogramming is associated with cancer cell survival and metastasis in a hostile envi-ronment with a limited nutrient supply, such as solid tumors. Little is known regarding the differences of bioenergetic adaptation between primary tumor cells and metastatic tumor cells in unfavorable microenvironments; to clarify these differences, the present study aimed to compare metabolic reprogramming of primary tumor cells and metastatic tumor cells. SW620 metastatic tumor cells exhibited stronger bioenergetic adaptation in unfavorable conditions compared with SW480 primary tumor-derived cells, as determined by the sustained elevation of glycolysis and regulation of the cell cycle. This remarkable glycolytic ability of SW620 cells was associated with high expression levels of hexokinase (HK)1, HK2, glucose transporter type 1 and hypoxia-inducible factor 1alpha. Compared with SW480 cells, the expression of cell cycle regulatory proteins was effectively inhibited in SW620 cells to sustain cell survival when there was a lack of energy. Furthermore, SW620 cells exhibited a stronger mesenchymal phenotype and stem cell characteristics compared with SW480 cells; CD133 and CD166 were highly expressed in SW620 cells, whereas expression was not detected in SW480 cells. These data may explain why metastatic cancer cells exhibit greater microenvironmental adaptability and survivability; specifically, this may be achieved by upregulating glycolysis, optimizing the cell cycle and reprogramming cell metabolism. The present study may provide a target metabolic pathway for cancer metastasis therapy. PMID- 30280200 TI - S100B regulates inflammatory response during osteoarthritis via fibroblast growth factor receptor 1 signaling. AB - The present study aimed to investigate the role of S100B in the inflammation process during osteoarthritis (OA). OA cartilage samples were collected for S100B expression analysis. S100B expression levels were significantly increased in patients with OA compared with the Controls (1.28+/-0.66 vs. 0.42+/-0.31; P=0.01) and were determined to be correlated with TNF-alpha (r=0.42; P=0.04) and IL-1beta (r=0.73; P=0.001) expression levels. Orthopedic casting tape was used to immobilize the right knee at 180 extension of adult female New Zealand white rabbits for 4 weeks to establish an OA model. Cartilage specimens from the medial femoral condyle of these rabbits were used for histological confirmation and immunohistochemical analyses, whereas synovial fluid was used in ELISA assays for tumor necrosis factor (TNF)-alpha and interleukin (IL)-1beta expression levels. Human synovial fibroblasts from the knee synovial tissues of normal patients with traumatic injury were transfected with S100B overexpression and knockdown plasmids and subjected to lipopolysaccharide (LPS) stimulation; subsequently, TNF alpha and IL-1beta expression levels in conditioned medium were determined by ELISA; S100B overexpression and knockdown significantly increased and decreased the TNF-alpha and IL-1beta expression levels, respectively. Increased TNF-alpha (573.3+/-15.4 vs. 102.6+/-8.7 pg) and IL-1beta (378.6+/-7.2 vs. 170.1+/-5.8 pg) expression levels were detected in OA model rabbits compared with the Control rabbits. Additionally, S100B, fibroblast growth factor (FGF)-1 and FGF receptor (FGFR)-1 mRNA and protein expression levels were increased in OA model rabbits compared with the Control group. FGFR1 knockdown significantly decreased TNF alpha and IL-1beta expression levels in LPS-stimulated S100B-overexpressing human synovial fibroblasts. S100B is involved in FGFR1 signaling-mediated inflammatory response during OA, which may be considered as a potential therapeutic target. PMID- 30280202 TI - Iliopsoas snapping hip: improving the diagnostic value of magnetic resonance imaging with a novel parameter. AB - OBJECTIVE: To illustrate an advanced imaging parameter that describes the course of the iliopsoas tendon, and evaluate its correlations with iliopsoas internal hip snapping syndrome. METHODS: This retrospective cohort study reviewed hip MRI images of all patients seen by a single surgeon between January 2015 and March 2016. The comparison group included all patients with clinical internal hip snapping, versus the control group that did not. MRI images were processed using minimum intensity projection. Measurements obtained of the pelvis and course of the iliopsoas tendon included: pelvic incidence, coronal angle, and sagittal opening angle (SOA). Comparison of measurements between the groups was performed with Mann-Whitney U analysis and receiver operator curve (ROC) plotting, with a significance cutoff of p = 0.05. RESULTS: The control group (n = 85) and comparison group (n = 48) demonstrated no difference in age or gender. Pelvic incidence was similar [51.3 (+/- 10.7) degrees control versus 52.2 (+/- 7.7) degrees comparison (p = 0.36)], as was coronal angle [13.9 (+/- 4.6) degrees control versus 14.8 (+/-4.8) degrees comparison (p = 0.15)]. There was a significant difference in SOA [137.0 (+/- 5.9) degrees control versus 141.9 (+/- 6.5) degrees comparison (p < 0.01)]. ROC analysis revealed SOA threshold of 140 degrees for clinical IP hip snapping (p < 0.01), with odds ratio 5.2 (2.4-11.3) for SOA > 140 degrees. CONCLUSIONS: Iliopsoas hip snapping is often part of a more complex disease process. While challenging to diagnose, advanced imaging parameters, like the sagittal opening angle, relate with clinical pathology. The SOA offers diagnostic value, with a threshold of greater than 140 degrees significantly correlating with clinical presentation. PMID- 30280203 TI - Perioperative adverse events in women undergoing concurrent urogynecologic and gynecologic oncology surgeries for suspected malignancy. AB - INTRODUCTION AND HYPOTHESIS: This study's objectives were to compare the incidence of adverse events after concurrent urogynecologic and gynecologic oncology surgery to gynecologic oncology surgery alone and to describe the frequency of modification in planned urogynecologic procedures. The authors hypothesized there would be no difference in major complications. METHODS: This was a retrospective matched cohort study of women who underwent concurrent surgery at a large tertiary care center between January 2004 and June 2017. Cohorts were matched by surgeon, surgery route, date, and final pathologic diagnosis. Perioperative data and postoperative adverse events classified by Clavien-Dindo grade were compared. RESULTS: One hundred and eight patients underwent concurrent surgeries, with 216 matched cohorts. Concurrent-case patients were more likely to be older, postmenopausal, have greater vaginal parity, have had preoperative chemotherapy, and have preoperative cardiac or pulmonary disease. There were no differences in intraoperative complications or Dindo grade >= 3 adverse events between groups, but there were more grade 2 adverse events in the concurrent cohort (44 vs 19%, p < 0.0001) including postoperative urinary tract infection (UTI) (26 vs 7%, p < 0.0001). Concurrent surgery remained associated with a higher incidence of grade >= 2 events on multivariate analysis [odds ratio (OR) 2.5, 95% confidence interval (CI) 1.5-4.2, p = 0.0004). Discharge with a urinary catheter was more frequent after concurrent cases (35 vs 2%, p < 0.0001). Planned urogynecologic procedures were modified in 10% (n = 11) of cases. CONCLUSIONS: Concurrent surgeries have an increased incidence of minor but not serious perioperative adverse events. One in ten planned urogynecologic procedures is either modified or abandoned during combined surgeries. PMID- 30280205 TI - Tips and tricks for endoscopic negative pressure therapy. AB - Endoscopic negative-pressure therapy (ENPT) is becoming a valuable tool in surgical complication management of transmural intestinal defects and wounds in the upper and lower gastrointestinal tract. Innovative materials for drains have been developed, endoscopic techniques adapted, and new indications for ENPT have been found. Based on our broad clinical experience, numerous tips and tricks are described, which contribute to the safety of dealing with the new therapy. The aim of this work is to present these methods. The focus is on describing the treatment in the esophagus. PMID- 30280204 TI - [Preconditioning prior to visceral oncological surgery : A paradigm shift in visceral surgery?] AB - BACKGROUND: Postoperative complications after complex visceral oncological surgery can lead to substantial impairment of patients. In addition, preoperative physical performance and the severity of postoperative complications determine the long-term recovery process of physical function. Therefore, preconditioning in the preoperative period should be an important part of the preoperative/neoadjuvant treatment. OBJECTIVE: The aim of this article is a critical appraisal of current concepts of prehabilitation as well as their development potential and applicability in visceral surgery. MATERIAL AND METHODS: Based on a selective literature review, current studies and implemented concepts are presented and therapy algorithms are provided. RESULTS: This study differs in primary outcome, design and temporal framework of the intervention. The study results showed positive effects of an active increase in physical fitness in the preoperative period with respect to the quality of life, convalescence and postoperative pulmonary complication rate. DISCUSSION: In addition to the assessment of the individual risk of complications by means of spiroergometry, a targeted nutrition and exercise program can increase the individual performance level prior to visceral surgery and, thus, influence the postoperative risk of complications. The performance should be understood as a modifiable risk factor, which can also be positively influenced in the preoperative phase, even in a short time period. Individual preoperative care optimizes the physical and psychological situation of patients. To ensure the required individual care, approaches must be created and pursued, which can be implemented in a decentralized way. PMID- 30280206 TI - [Update on endocrine hypertension]. AB - Endocrine disorders are the most common causes of secondary hypertension. Early diagnosis and specific treatment are crucial for improvement of the prognosis. This article provides an overview on which clinical constellations point to an increased risk of secondary causes of hypertension. These include spontaneous hypokalemia, young age at onset of hypertension, adrenal incidentaloma and therapy refractive arterial hypertension. The basic diagnostics include determination of the aldosterone to renin ratio, measurement of free plasma metanephrines and a 1 mg dexamethasone suppression test. Borderline results require repeated control testing and/or confirmatory testing under standardized test conditions. In cases of repeatedly conspicuous results referral to a specialized clinic should be considered for further clarification and confirmation of the diagnosis. Imaging diagnostics may constitute an adjunct to laboratory testing after the diagnosis has been confirmed. Therapeutic algorithms vary depending on the underlying endocrine disease. PMID- 30280207 TI - Twelve-year trend in the use of zolpidem and physicians' non-compliance with recommended duration: a Korean national health insurance database study. AB - OBJECTIVES: Abuse of zolpidem has sporadically been reported and little is known regarding nationwide patterns of zolpidem use in Korea. This study investigates the extent of zolpidem usage exceeding the recommended duration and the predictors. METHODS: We conducted a drug utilization study using the national sample cohort database of the Korea National Health Insurance Corporation between 2002 and 2013. The study subjects were patients treated with zolpidem in the outpatient setting. An episode was defined as a period of continuous zolpidem therapy. The provider-based episode allowed for a gap of up to 3 days between two consecutive prescriptions from the same institution. The person-based episode allowed for a gap of up to 3 days, regardless of institution. We calculated the proportion of zolpidem use for periods over 30 days and conducted logistic regression analyses to investigate the relevant predictors. An adjusted odds ratio (aOR) with a 95% confidence interval (CI) was estimated for each predictor. RESULTS: The usage of zolpidem is dramatically increased by approximately 18 times since zolpidem was authorized in the market (1181 in 2002 vs. 21,399 in 2013). The treatment duration in 8.3% of episodes exceeded 30 days out of 75,087 zolpidem users. The odds of zolpidem prescription exceeding 30 days were highest in patients aged 65 years and older (aOR = 2.13, 95% CI 1.78-2.53) and at tertiary hospitals (aOR = 2.14, 95% CI 1.68-2.72). Women were more likely than men to be treated with zolpidem for over 30 days. CONCLUSION: We found dramatic increase of zolpidem use from 2002 to 2013. In 8.3% of the prescribed episodes of zolpidem, the recommended duration was exceeded. Efforts are required to reduce prescriptions that are inconsistent with the recommended guidelines for older patients, women, and in tertiary hospitals. PMID- 30280208 TI - Non-steroidal anti-inflammatory drugs and risk of Parkinson's disease in the elderly population: a meta-analysis. AB - PURPOSE: Several studies have explored the impact of non-steroidal anti inflammatory drugs (NSAIDs) and the risk of Parkinson disease (PD). However, the extent to which NSAIDs may increase or decrease the risk of PD remains unresolved. We, therefore, performed a meta-analysis of relevant studies to quantify the magnitude of the association between NSAID use and PD risk in the elderly population. METHODS: The electronic databases such as PubMed, EMBASE, Scopus, Google Scholar, and Web of Science were used to search the relevant articles published between January 1990 and December 2017. Large (n >= 1000) observational design studies with a follow-up at least 1 year were considered. Two authors independently extracted information from the included studies. Random effect model was used to calculate risk ratios (RRs) with 95% confidence interval (Cl). RESULTS: A total of 17 studies with 2,498,258 participants and nearly 14,713 PD patients were included in the final analysis. The overall pooled RR of PD was 0.95 (95%CI 0.860-1.048) with significant heterogeneity (I2 = 63.093, Q = 43.352, p < 0.0001). In the subgroup analysis, the overall pooled RR of PD was 0.90 (95%CI 0.738-1.109), 0.96 (95%CI 0.882-1.055), and 0.99 (95%CI 0.841-0.982) from the studies of North America, Europe, and Asia. Additionally, long-term use, study design, individual NSAID use, and risk of PD were also evaluated. CONCLUSION: Despite the neuroprotective potential of NSAIDs demonstrated in some experimental studies, our findings suggest that there is no association between NSAIDs and the risk of Parkinson disease at the population level. Until further evidence is established, clinicians need to be vigilant ensuring that the use of NSAIDs remains restricted to their approved anti-inflammatory and analgesic effect. PMID- 30280209 TI - [Focused sonography in orthopedic emergencies]. AB - Focused sonography of the musculoskeletal system in the emergency room should be done for time-effective and symptom-oriented detection of suspected findings. Analogous to other point-of-care ultrasound in emergency medicine, it is by definition not a complete ultrasound examination of the respective organ (e.g., shoulder, elbow). It allows detection of important findings (luxation, effusion, fracture or rupture) with good to excellent diagnostic accuracy. Afterwards computed tomography, magnetic resonance imaging or complete sonographic examination (according to the guidelines of the working group Bewegungsorgane der Deutschen Gesellschaft fur Ultraschall in der Medizin, which are identical to those of the working group Orthopadie und Unfallchirurgie) should be added as clinically required. Sonography of the musculoskeletal system in the emergency room can be performed on the lying or sitting patient, except when examining the shoulder, in which there is a difference. The interventional procedures are safe, useful and time saving. PMID- 30280211 TI - Assessment of the Australian Bureau of Meteorology wet bulb globe temperature model using weather station data. AB - Exertional heat illnesses affect thousands of athletes each year and are a leading cause of death in sports. The wet bulb globe temperature (WBGT) is widely used as a heat stress metric in athletics for adjusting activities. The WBGT can be measured on-site with portable sensors, but instrument cost may provide a barrier for usage. Modeling WBGT from weather station data, then, presents an affordable option. Our study compares two WBGT models of varying levels of sophistication: the Australian Bureau of Meteorology (ABM) model which uses only temperature and humidity as inputs and a physically based model by Liljegren that incorporates temperature, humidity, wind speed, and solar radiation in determining WBGT outputs. The setting for the study is 19 University of Georgia Weather Network stations selected from across the state of Georgia, USA, over a 6 year period (2008-2014) during late summer and early fall months. Results show that the ABM model's performance relative to the Liljegren model varies based on time of day and weather conditions. WBGTs from the ABM model are most similar to those from the Liljegren model during midday when the assumption of moderately high sun most frequently occurs. We observed increasingly large positive biases with the ABM model both earlier and later in the day during periods with lower solar radiation. Even during midday, large (>= 3 degrees C) underestimates may occur during low wind conditions and overestimates during periods with high cloud cover. Such differences can lead to inaccurate activity modification and pose dangers for athletes either by underestimating heat-related hazards or by imposing an opportunity cost if practice activities are limited by overestimating the heat hazard. PMID- 30280212 TI - Valuation of the human thermal discomfort index for the five Brazilian regions in the period of El Nino-Southern Oscillation (ENSO). AB - Brazil is an extensive country with five administrative regions that have different climates, mainly due to their geographic locations. The El Nino Southern Oscillation influences the regime of temperature and precipitation of the Brazilian regions, which can directly affect the thermal discomfort of the population. The objective of this study was to evaluate the human thermal discomfort index (HDI) in the five regions of Brazil for El Nino, La Nina, and neutral years from 1979 to 2017, as well as the influence of the degree of intensity of the Pacific Ocean anomaly in the thermal conditions of the Brazilian regions. Monthly data on air temperature and dewpoint temperature obtained from the ERA-Interim reanalysis were used. The HDI was calculated using specific equations. The results were analyzed by means of composition fields. From the results, it was possible to conclude that the El Nino and La Nina phenomena influence the HDI of the Brazilian regions. El Nino increases the discomfort due to the heat and the La Nina causes them to decrease. This study is important since these phenomena, by influencing thermal conditions, directly affect the well-being and health of the Brazilian population. PMID- 30280213 TI - Treatment of steroid-resistant nephrotic syndrome in the genomic era. AB - The pathogenesis of steroid-resistant nephrotic syndrome (SRNS) is not completely known. Recent advances in genomics have elucidated some of the molecular mechanisms and pathophysiology of the disease. More than 50 monogenic causes of SRNS have been identified; however, these genes are responsible for only a small fraction of SRNS in outbred populations. There are currently no guidelines for genetic testing in SRNS, but evidence from the literature suggests that testing should be guided by the genetic architecture of the disease in the population. Notably, most genetic forms of SRNS do not respond to current immunosuppressive therapies; however, a small subset of patients with monogenic SRNS will achieve partial or complete remission with specific immunomodulatory agents, presumably due to non-immunosuppressive effects of these agents. We suggest a pragmatic approach to the therapy of genetic SRNS, as there is no evidence-based algorithm for the management of the disease. PMID- 30280214 TI - Expression profiles of pro-inflammatory and pro-apoptotic mediators in secondary tethered cord syndrome after myelomeningocele repair surgery. AB - PURPOSE: The literature on histopathological and molecular changes that might underlie secondary tethered cord syndrome (TCS) after myelomeningocele (MMC) repair surgeries remains sparse. To address this problem, we analyzed specimens, which were obtained during untethering surgeries of patients who had a history of MMC repair surgery after birth. METHODS: Specimens of 12 patients were analyzed in this study. Clinical characteristics were obtained retrospectively including pre-operative neurological and bowel/bladder-function, contractures and spasticity of lower extremities, leg and back pain, syringomyelia, and conus position on spinal MRI. Cellular marker expression profiles were established. Further, immunoreactivities (IR) of IL-1beta/IL-1R1, TNF-alpha/TNF-R1, and HIF 1alpha/-2alpha were analyzed qualitatively and semi-quantitatively by densitometry. Co-labeling with cellular markers was determined by multi fluorescence-labeling. Cytokines were further analyzed on mRNA level. Immunostaining for cleaved PARP and TUNEL was performed to detect apoptotic cells. RESULTS: Astrocytosis, appearance of monocytes, activated microglia, and apoptotic cells in TCS specimens were one substantial finding of these studies. Besides neurons, these cells co-stained with IL-1beta and TNF-alpha and their receptors, which were found on significantly elevated IR-level and partially mRNA level in TCS specimens. Staining for HIF-1alpha/-2alpha confirmed induction of hypoxia-related factors in TCS specimens that were co-labeled with IL-1beta. Further, hints for apoptotic cell death became evident by TUNEL and PARP-positive cells in TCS neuroepithelia. CONCLUSIONS: Our studies identified pro-inflammatory and pro-apoptotic mediators that, besides mechanical damaging and along with hypoxia, might promote TCS development. Besides optimizing surgical techniques, these factors should also be taken into account when searching for further options to improve TCS treatment.

AB - PURPOSE: This study aims to investigate risk factors for refracture of the forearm in children treated with elastic stable intramedullary nailing (ESIN). METHODS: Clinical data of 267 patients who had been treated for forearm fractures by ESIN in our hospital from January 2010 to December 2014 were retrospectively reviewed. Risk factors for forearm refractures were determined using logistic regression analysis. RESULTS: Forearm refractures occurred in 11 children. Univariate analysis revealed that age, body weight, number of fractures, open fracture, nail diameter, and immobilization time were not associated with refractures. However, gender (male, P = 0.042) and fracture location (lower third, P = 0.007) were significantly associated with refractures. Multivariate analysis revealed that fracture location was an independent risk factor for forearm refractures (P = 0.031). CONCLUSION: Forearm refracture is uncommon in children treated with ESIN. Fracture location is an independent risk factor for forearm refractures in these patients.

AB - PURPOSE: Management of acute open tibial fractures with critical bone defect remains a challenge in trauma surgery. Few and heterogeneous cases have been reported about the treatment with the induced membrane technique. METHODS: We prospectively evaluated three patients treated with the induced membrane technique for acute Gustilo IIIB tibial fractures with critical bone defect. Success treatment was defined by bone union with patient pain free. Clinical and radiological evaluations were performed regularly until healing, then annually and with a minimum follow-up of five years. RESULTS: In all patients but one, a success was recorded, respectively, at four and six months. These two patients were pain free until the final follow-up, and no graft resorption or secondary complications related to the index surgery were observed. The third case was managed successfully with a bone transport technique. CONCLUSION: The induced membrane technique is an alternative good option for the treatment of these severe lesions. PMID- 30280217 TI - Computed tomography evaluation of total knee arthroplasty implants position after two different surgical methods of implantation. AB - PURPOSE: The objectives of this study were to determine the reliability of a novel method of measuring the rotational alignment of an anatomical tibial tray, the difference in the rotational alignment of the femoral and tibial component according to pure measured resection or blended technique with tensor, and, finally, the difference in terms of clinical results according to the two different methods. PATIENTS AND METHODS: We performed a total of 60 consecutive TKAs: 30 according to pure measured resection and 30 according to blended technique with tensor (FuZion(r)). Clinical scores and CT scan were done at six months to measure patient's outcome and prosthetic components rotation. RESULTS: The method of measurement of tibial tray had high agreement between different radiological observers. Mean external rotation alignment of the femur was 2.7 degrees in standard group and 0.5 degrees in the FuZion(r) group. For all clinical indices, we observed a large and significant improvement at follow-up, better in blended technique group, but without a clear superiority, and no statistically significant difference was evident between the two groups. At follow-up, HSS was to 89.7 in the FuZion(r) group and 89.0 in the standard group, KSS (clinical) was 92.6 in and 91.3 respectively, and KSS (Functional) was 91.0 in the FuZion(r) group and 87.6 in the standard group. CONCLUSIONS: Our CT measurement method is reliable and reproducible. All patients operated with this personalized knee system design obtained excellent results; the customization of femoral rotation with a blended technique is, probably, the key to optimize the outcomes and achieve the state of forgotten knee. PMID- 30280218 TI - Preliminary results of autologous adipose-derived stem cells in early knee osteoarthritis: identification of a subpopulation with greater response. AB - PURPOSE: The purpose of this study was to report the clinical and functional results of a series of patients with early knee osteoarthritis (KOA) treated with the intra-articular injection of autologous adipose-derived stem cells (aASCs) plus arthroscopic debridement. The hypothesis was that protocol would significantly improve the clinical and functional outcomes in patients with early KOA. METHODS: Fifty-two patients with early KOA, who received arthroscopic debridement followed by percutaneous injection of aASCs, were enrolled into the study and retrospectively analyzed with an average follow-up of 15.3 (range, 6 to 24) months. Patients were assessed through the IKS knee and function scores and VAS pain scale. RESULTS: The mean IKS knee score improved from 37.4 (range, 14 to 79) points pre-operatively to 62.6 (range, 27 to 95) points at the latest follow up (p < < 0.01). The mean IKS function score improved from 57.2 (range, 25 to 100) points pre-operatively to 83.0 (range, 35 to 100) points at the latest follow-up (p < < 0.01). The mean VAS score decreased from 8.5 (range, 3 to 10) pre-operatively to 5.1 (range, 0 to 8) at the latest follow-up (p < < 0.01). Additionally, patients with a pre-operative VAS score greater than 8 were found to show greater clinical and functional benefits compared with patients with VAS score lower than 8. CONCLUSIONS: The knee injection of aASCs associated to arthroscopic debridement increased significantly the clinical and functional scores in patients with early KOA at a mid-term follow-up, especially those with higher pre-operative VAS scores. PMID- 30280219 TI - Two cases of subcutaneous dirofilariasis in Barcelona, Spain. AB - In recent years, the number of reported cases of human dirofilariasis in Europe has increased and the circulation of Dirofilaria spp. in mosquitoes in several European countries has been proven. We report here two likely autochthonous cases of subcutaneous human dirofilariasis from Barcelona, Spain, caused by Dirofilaria repens. The potential for an increase in human infection is high given the number of cases published recently and the ability of vectors to spread through the Mediterranean basin. PMID- 30280221 TI - Intrahepatic Balloon Tamponade for Penetrating Liver Injury: Rarely Needed but Highly Effective. AB - BACKGROUND: Severe penetrating liver injuries are associated with high rates of morbidity and mortality. The objective of this study was to demonstrate the 15 year experience of a Level 1 US trauma center with use of intrahepatic balloon tamponade for penetrating liver injuries in adult patients. METHODS: Operative notes were used to identify cases employing intrahepatic balloon tamponade. Charts were reviewed for patient characteristics, injury characteristics, morbidity, and in-hospital mortality. RESULTS: Of the 4961 penetrating trauma patients admitted during the study period, 279 (5.6%) had liver injury and underwent exploratory laparotomy. Intrahepatic balloon tamponade was attempted in nine patients (3.2%). Two of the nine patients (22%) were in cardiac arrest at time of balloon placement and died during the index operation; both had retrohepatic IVC injury combined with cardiopulmonary injury. In patients who reached the operating room alive and had spontaneous circulation at the time of balloon placement, utilization of this technique was associated with 100% survival. CONCLUSION: Although rarely needed, trauma surgeons must be prepared to use intrahepatic balloon tamponade as one surgical technique to control major hepatic injuries. PMID- 30280222 TI - Relationships Between Expertise, Crew Familiarity and Surgical Workflow Disruptions: An Observational Study. AB - BACKGROUND: Teamwork is an essential factor in reducing workflow disruption (WD) in the operating room. Team familiarity (TF) has been recognized as an antecedent to surgical quality and safety. To date, no study has examined the link between team members' role and expertise, TF and WD in surgical setting. This study aimed to examine the relationships between expertise, surgeon-scrub nurse familiarity and WD. METHODS: We observed a convenience sample of 12 elective neurosurgical procedures carried out by 4 surgeons and 11 SN with different levels of expertise and different degrees of familiarity between surgeons and SN. We calculated the number of WD per unit of coding time to control for the duration of operation. We explored the type and frequency of WD, and the differences between the surgeons and SN. We examined the relationships between duration of WD, staff expertise and surgeon-scrub nurse familiarity. RESULTS: 9.91% of the coded surgical time concerned WD. The most frequent causes of WD were distractions (29.7%) and colleagues' interruptions (25.2%). This proportion was seen for SN, whereas teaching moments and colleagues' interruptions were the most frequent WD for surgeons. The WD was less high among expert surgeons and less frequent when surgeon was familiar with SN. CONCLUSIONS: The frequency of WD during surgical time can compromise surgical quality and patient safety. WD seems to decrease in teams with high levels of surgeon-scrub nurse familiarity and with development of surgical expertise. Favoring TF and giving feedback to the team about WD issues could be interesting ways to improve teamwork. PMID- 30280220 TI - The potential effects of silver and gold nanoparticles as molluscicides and cercaricides on Schistosoma mansoni. AB - Schistosomiasis seriously affects human health in tropical regions. Its prevention is more important than treatment, raising the need for effective control methods. Recently, the role of nanomaterials in medical science has been growing. The present study aimed to evaluate the potential effects of silver (Ag) and gold (Au) nanoparticles (NPs) on Biomphalaria alexandrina snails and Schistosoma mansoni cercariae in vitro and to assess their effects on the infectivity of cercariae in vivo. The in vitro study proved that Ag and Au NPs were effective in killing B. alexandrina snails, with 30 MUg/ml Ag and 160 MUg/ml Au causing 100% mortality. The LC50 of 9.68 MUg/ml for Ag NPs and 133.7 MUg/ml for Au NPs prevented snail infection with S. mansoni miracidia. Furthermore, Ag NPs at 50 MUg/ml and Au NPs at 100 MUg/ml increased the mortality of S. mansoni cercariae in a dose- and time-dependent manner, reaching 100% mortality after 1 h. The in vivo study found that Ag NPs prevented the occurrence of infection when cercariae were treated before the infection by either the tail immersion (TI) or subcutaneous (SC) route, as proven by parasitological parameters and by the absence of granuloma formation in hepatic tissue. Meanwhile, infection of mice by untreated cercariae followed by treatment with NPs 1 h post-infection (PI) caused a decrease in egg count/g intestine and egg count/g liver in the TI-infected group only. The oogram patterns and granuloma formation results were similar between infection control and the SC-infected group. On the other hand, Au NPs led to a decrease in total worm burden (TWB) in all tested groups, with a decrease in egg count/g intestine and egg count/g liver in TI-infected groups with either pre-treated or post-treated cercariae, in contrast to SC-infected groups. However, the oogram patterns and granuloma formation showed similar results to infection control. Ag and Au NPs have potential as molluscicides and cercaricides in vitro and can prevent or modulate the infectivity of cercariae in vivo.

PMID- 30280224 TI - Are mechanical and chemical trauma the reason of meatal stenosis after newborn circumcision? AB - : Mechanical and chemical trauma are a widely accepted theories to explain the pathogenesis of meatalstenosis after newborn circumcision. The aim of the present study was to explore the theory that an exposed glans is prone to meatal stenosis. This was done by a novel investigation of boys who were born with "hooded prepuce", a condition in which the glans is completely exposed. Physical examination, lower urinary tract symptoms, urethral meatus configuration, and surgical procedures of 18 children admitted for routine circumcision, who had congenital hooded prepuce with normally located urethral meatus, were analyzed. The study period was 2013 and 2018. All the cases have been seen because of neonatal circumcision request, but was postponed due to hooded prepuce. The only presenting complaint in children was a cosmetically unattractive appearance. There were no symptoms associated with meatal stenosis, they circumcised in an average of 6 years and non of them required any additional procedure. CONCLUSION: Meatal stenosis did not occur in cases whose glans penis are naked with hooded prepuce. These findings do not support the default chemical and mechanical trauma theories. Hooded prepuce without any penile anomalies is only a cosmetically unattractive appearance and circumcision can correct this. What is known: * The common theory of meatal stenosis etiology is that the meatus undergoes irritation with chemical/mechanical trauma in the absence of a prepuce after newborn circumcision. * Circumcision is usually postponed in newborns with hooded prepuce. What is new: * We did not notice meatal stenosis in cases whose urethral meatus were not covered with a prepuce congenitally. Ammoniacal dermatitis or mechanical trauma theories may not explain the cause of meatal stenosis. * Hooded prepuce is not a handicap to newborn circumcision. It is just a cosmetic problem and circumcision can solve it. PMID- 30280226 TI - High-affinity graphene oxide-encapsulated magnetic Zr-MOF for pretreatment and rapid determination of the photosensitizers hematoporphyrin and hematoporphyrin monomethyl ether in human urine prior to UPLC-HRMS. AB - In this paper, a high-affinity graphene oxide-encapsulated magnetic Zr-MOF (GO Mag@Zr-MOF) was synthesized and characterized by SEM, TEM, and XPS for its morphology, structure, and components. Subsequently, the as-prepared GO-Mag@Zr MOF was, for the first time, employed as magnetic solid-phase extraction (MSPE) adsorbent for pretreatment and determination of photodynamic therapy (PDT) with the photosensitizers hematoporphyrin (Hp) and hematoporphyrin monomethyl ether (HMME) in human urine samples coupled with ultra-performance liquid chromatography-high resolution mass spectrometry (UPLC-HRMS). The synthesized GO Mag@Zr-MOF revealed excellent adsorption efficiency for Hp and HMME in urine samples. Under optimal conditions, the spiked recoveries of the developed method were in the range of 89.5-105.6% with RSDs less than 10%. The limits of detection (LODs) were found to be 0.036 and 0.042 MUg/L for Hp and HMME, respectively, while limits of quantitation (LOQs) were 0.12 and 0.14 MUg/L. The proposed method was found to be rapid, effective, sensitive, and accurate for clinical analysis. Moreover, this paper, for the first time, carefully expounded the mass spectrum cracking mechanisms of Hp and HMME. Graphical abstract ?. PMID- 30280225 TI - Direct bacteria analysis using laserspray ionization miniature mass spectrometry. AB - An atmospheric pressure laserspray ionization mass spectrometry (AP-LSI mini MS) has been developed and employed in the fast analysis of bacteria. Without using surfactants or any extracting methods, 21 foodborne bacteria from 12 genera were directly analyzed. Typical fingerprints of small molecules and lipids were detected and recognized in the mass spectra with high reproducibility. Furthermore, a supervised multivariate statistics method, orthogonal partial least squares (OPLS), was applied, and these bacteria could be differentiated at both genus and species levels. With improved performance in the future, AP-LSI mini MS could be a simple, effective, and fast approach for direct bacteria analysis on the field. PMID- 30280227 TI - Development and validation of an LC-MS/MS assay for the quantification of dolutegravir extracted from human hair. AB - Measurement of drug concentrations in hair provides a non-invasive approach to assess drug adherence. Here, we report on the development and validation of a method for the quantification of the antiretroviral dolutegravir (DTG) extracted from human hair. DTG is extracted from hair samples by sonication and incubation in 50:50 methanol:acetonitrile with 2% formic acid overnight at 40 degrees C. Following extraction, samples are analyzed by reverse-phase chromatography on a Waters Atlantis T3 (50 * 2.1 mm, 3-MUm particle size) column with subsequent detection by electrospray ionization in positive ion mode on an AB Sciex API-5000 triple quadrupole mass spectrometer. The stable, isotopically labeled 13C,d5-DTG is used as an internal standard in the assay. The calibration range is 5-10,000 pg DTG/mL of extraction solvent with the ability to extract between 1 and 10 mg of hair/mL of extraction solvent. The assay was linear, accurate (inter-assay %bias within +/- 6.5%), and precise (inter-assay %CV <= 10.3%). The assay was successfully used to analyze clinical samples from subjects on DTG regimens. Analysis of clinical samples suggested the potential presence of a degradation product, which was subsequently confirmed to occur with exposure to sunlight. The degradation of DTG could complicate absolute interpretation of clinical results, but the presence of this degradation product is easily evaluated with this assay to aid in data interpretation. PMID- 30280228 TI - Portable glucose meter: trends in techniques and its potential application in analysis. AB - A blood glucose meter is an electronic medical device used for determining the concentration of glucose in blood. These meters have undergone five phases of development: washed blood glucose meters, wiped blood glucose meters, colorimetric blood glucose meters, electrochemical blood glucose meters, and micro, multiple site blood glucose meters. Thanks to their speed, portability, low cost, and easy operation, blood glucose meters have been widely available for use in clinical diagnosis. Recently, coupling of target recognition elements (antibody-antigen recognition, nucleic acid hybridization, enzyme recognition, and click chemistry) with signal transduction and amplification strategies (glucose-generating enzymes, nicotinamide adenine dinucleotide (NADH)-generating enzymes, encapsulated glucose, nanomaterials, and cyclic amplification of DNA) has allowed various targets to be determined via the relationship between the signal of the blood glucose meter and the concentration of targets. In this paper, a brief review of the development and mechanism of blood glucose meters is given first. Then, more details on the application of blood glucose meters in analysis are described, including biomedical analysis, food analysis, and environmental analysis. Finally, the prospect of future development of blood glucose meters is also discussed. Graphical abstract ?. PMID- 30280229 TI - Drosophila melanogaster odorant receptors as volatile compound detectors in forensic science: a proof-of-concept study. AB - The ability to detect and identify substances based on the volatile compounds (odors) they emit is relied upon heavily for numerous investigative purposes. Animals have an innate olfactory sensitivity and selectivity that out-performs current instrumentation. This has led to immense interest in their employment as chemical sensors for a range of applications, including forensic science, both as whole organisms and as sensing elements in biosensors. Using electrophysiological and calcium imaging assays, this research examined the response of Drosophila melanogaster olfactory receptors (ORs) to odor compounds significant in forensic science and assessed their potential utility as volatile compound sensors. This investigation illustrated the different sensitivities, selectivities, and sensing features of individual ORs and demonstrated that their employment for detection purposes is feasible. While further research expanding on this study will be required to demonstrate the performance characteristics that an OR-based detection system will ultimately possess, this research provides an encouraging first step towards the goal of utilizing isolated biological ORs as volatile compound sensors in forensic science. PMID- 30280231 TI - [Systematic literature search in PubMed : A short introduction]. AB - In order to identify current (and relevant) evidence for a specific clinical question within the unmanageable amount of information available, solid skills in performing a systematic literature search are essential. An efficient approach is to search a biomedical database containing relevant literature citations of study reports. In this article, we explain step by step how to perform a systematic literature search via PubMed (MEDLINE) by means of an example research question in the field of ophthalmology. First, we demonstrate how to translate the clinical problem into a well-framed and searchable research question, how to identify relevant search terms and how to conduct a text word search and a search with keywords in MeSH terms. We then show how to limit the number of search results if the search yields too many irrelevant hits and how to increase the number in the case of too few citations. Finally, we summarize all essential principles that guide a literature search via PubMed. PMID- 30280230 TI - Preparation and characterization of large-format macroporous cryogel disks for use in affinity chromatography and biotechnological applications. AB - We have prepared and evaluated larger format phage-bound epoxy-cryogel columns in order to increase the yield of bound target. Freezing thermograms showed that larger column formats (2.5-5 cm diameter) are not usable due to irregular polymerization phenomena. Preparing thin disks of 0.5 cm height with similar diameter proved to be an excellent alternative. Disks could be stacked and run in a chromatographic setup. In this way, we could increase the matrix volume, ligand binding capacity, and finally the yield of bound target. By increasing the column volume about sevenfold, we observed a 12-fold increase of ligand density and a sevenfold increase in the yield of protein recovery in a column where phages were attached without spacer and a 10- to 34-fold increase in a spacer column, depending on the spacer used.

AB - Lipedema is a symmetrical disorder of the subcutaneous adipose tissue that affects almost exclusively women in postpubescent age. The trinity of disfiguring hyperplastic adipose tissue of the proximal extremities, increasing pain over time and bruising is characteristic. Lymphedema can occur in both sexes and is differentiated into primary and secondary subtypes. Symmetry is not a prerequisite for diagnosis. Characteristic for lymphedema is the disproportion between lymphatic fluid and the capacity of lymphatic vessels. The most distal body parts are always more severely affected than proximal parts. In the initial phases lymphedema is painless but in advanced stages tension pain can occur. The combination of both disorders has been described; however, lipedema is not responsible for subsequent lymphedema in contrast to central obesity, which significantly increases the risk of lymphedema. The differential diagnosis is of utmost importance for a meaningful management. PMID- 30280234 TI - Phenotyping Thermal Responses of Yeasts and Yeast-like Microorganisms at the Individual and Population Levels: Proof-of-Concept, Development and Application of an Experimental Framework to a Plant Pathogen. AB - Deciphering the responses of microbial populations to spatiotemporal changes in their thermal environment is instrumental in improving our understanding of their eco-evolutionary dynamics. Recent studies have shown that current phenotyping protocols do not adequately address all dimensions of phenotype expression. Therefore, these methods can give biased assessments of sensitivity to temperature, leading to misunderstandings concerning the ecological processes underlying thermal plasticity. We describe here a new robust and versatile experimental framework for the accurate investigation of thermal performance and phenotypic diversity in yeasts and yeast-like microorganisms, at the individual and population levels. In addition to proof-of-concept, the application of this framework to the fungal wheat pathogen Zymoseptoria tritici resulted in detailed characterisations for this yeast-like microorganism of (i) the patterns of temperature-dependent changes in performance for four fitness traits; (ii) the consistency in thermal sensitivity rankings of strains between in planta and in vitro growth assessments; (iii) significant interindividual variation in thermal responses, with four principal thermotypes detected in a sample of 66 strains; and (iv) the ecological consequences of this diversity for population-level processes through pairwise competition experiments highlighting temperature dependent outcomes. These findings extend our knowledge and ability to quantify and categorise the phenotypic heterogeneity of thermal responses. As such, they lay the foundations for further studies elucidating local adaptation patterns and the effects of temperature variations on eco-evolutionary and epidemiological processes. PMID- 30280235 TI - [Biologics and further new drugs for rheumatic diseases since 2000]. AB - BACKGROUND: Rheumatoid arthritis (RA), psoriatic arthritis and axial spondyloarthritis are severe diseases, which without adequate treatment lead to extremely reduced mobility, functional status and quality of life. OBJECTIVE: The effects of biologics and further new antirheumatic drugs on the burden of disease. METHODS: Evaluation of study results and register data dealing with the efficacy and safety of these drugs. RESULTS: Biologics have been proven to dramatically improve the outcome of all three diseases and contributed to the fact that remission is a realistic target today. In addition, the cardiovascular risk and mortality in RA have been reduced and structural damage is considerably blocked by biologics. Recently Janus kinase (JAK) inhibitors contributed to the treatment possibilities in the same way. Biologics as well as JAK inhibitors offer an excellent safety profile and tolerability with infections being the most important risk. CONCLUSION: With the availability of biologics and additional new drugs all three diseases have lost the status of difficult to treat diseases. Their usage according to the guidelines ensures that the burden of disease can been minimalized in most cases. The benefit-risk profile of these drugs has been shown to be excellent.

Due to its rarity, there is no standard therapeutic approach. PMID- 30280237 TI - Gender differences in paid employment after retirement : Psychosocial working conditions and well-being. AB - BACKGROUND: An increasing number of persons continue to work after retirement age. This decision is often different between men and women as well as working histories, sectors and hierarchical positions; however, whether gender differences in working conditions and occupational well-being also exist in paid employment after retirement (PEAR) has not yet been investigated. OBJECTIVE: This study aimed to examine gender differences in working conditions and well-being of workers in PEAR. MATERIAL AND METHODS: In this study 784 employees (23.5% female) aged 65 years and older who were contracted by a Dutch temporary employment agency, participated in the baseline survey in 2011. Furthermore, a panel of 228 employees (25.9% female) participated again during a second wave in 2012. Job demands, job control, emotional exhaustion and job engagement were assessed at both time points by validated self-reporting measures. RESULTS: Female employees worked fewer years in paid employment before 65 years of age, were more likely to be single, divorced or widowed, had a smaller income and worked less hours during PEAR than men. In the baseline analysis, females reported less job control and higher job stress than men. No gender differences were found on emotional exhaustion, engagement or job demands. Over the study period emotional exhaustion only increased in females. The longitudinal trend of job demands, control and engagement did not significantly differ between both sexes. CONCLUSION: The results suggest that working conditions of PEAR are less favorable for women than for men. Furthermore, the longitudinal trend of emotional exhaustion seems to be more disadvantageous for women. PMID- 30280238 TI - [Development and validation of the Mini Dental Assessment : A procedure for improved estimation of need for dental treatment in geriatrics]. AB - BACKGROUND: In the future there will be an increasing demand for professional care with simultaneous retention of the dentition in older people. Due to inadequate dental knowledge, it is often not possible for caregivers to adequately assess dental deficits. OBJECTIVE: The aim of the study was to develop and validate a simple tool (Mini Dental Assessment, MDA) to assess possible dental treatment needs (DTN) of residential geriatric facilities by nursing personnel. MATERIAL AND METHODS: In the study 169 patients (51 from the University Hospital Giessen, 118 from the Bonifatius Hospital Lingen) underwent a dental examination. The dental status was evaluated based on the California Dental Association (CDA) criteria and the DTN determined. In addition, the time since the patients last visit to a dentist (TLVD) and denture age (DA) were documented and a chewing function test (carrot eating test, CET) was carried out. In a second study 155 patients were examined (115 from the University Hospital Giessen, 40 from the Bonifatius Hospital Lingen) corresponding to the reference sample and including a further chewing function test (after Schimmel und Slavicek) and questionnaires on quality of life (Oral Health Impact Profile (OHIP), Denatl Impact on Daily Living (DiDDL)). RESULTS: A total of 108 patients required dental treatment. The mean value (+/-SD) for the TLVD was 2.5 +/- 3.8 years and 10.8 +/- 8.9 years for the DA. There was a positive correlation (Spearman, P < 0.005) between the DTN and degree of comminution in the CET (3.4 +/- 1.8 grade). Based on the results an assessment tool was developed using the variables CET, TLVD and DA weighted by the respective regression coefficients (10:3:1). The resulting mean total MDA score was 51.32 +/- 28.14. A sensitivity/specificity analysis was conducted and a receiver operating characteristic (ROC) curve calculated (area under curve, AUC: 0.805; 95% CI: 0.738-0.873). The ROC curve from the follow-up study showed a good agreement with the ROC curve from the reference study (AUC 0.829, 95% CI: 0.751-0.907). CONCLUSION: Based on the results of the study it could be shown that the MDA is a suitable instrument for making a valid statement on the assessment of DTN of patients in long-term care facilities. The validation study revealed the validity of the MDA in its originally developed form and the addition of two further chewing function tests did not significantly improve the validity of the MDA. Overall, the MDA appears to be an appropriate tool to help nursing home personnel to assess the necessity for nursing home residents to visit a dentist. PMID- 30280239 TI - Transition to retirement in the healthcare sector : Working conditions and attitudes of older workers. AB - BACKGROUND: The aging of societies will increase the need for healthcare services and lead to a growing number of older employees. These two developments are relevant in the healthcare sector (HCS), which is of rising societal and economic importance and at the same time employs many older people. OBJECTIVE: This article, which was written within the EXTEND project, investigates the working conditions and the prospective retirement age of older employees in the HCS in comparison to other sectors and explores what companies are doing to address the needs of this group. MATERIAL AND METHODS: The analysis was conducted as a mixed methods approach. The quantitative part was based on data derived from the Transitions and Old Age Potential (TOP) study in which older German employees were asked about their working conditions and retirement transitions. Matching techniques (coarsened exact matching) were used to investigate differences between sectors. The sample consisted of 114 employees aged between 55 and 65 years, working in the HCS and their statistical twins. The qualitative analysis was based on case studies in two inpatient care organizations and two hospitals in Germany. A total of 23 semistructured interviews with staff members and with representatives of the management were carried out and thematically analyzed. RESULTS: The results showed that older employees in the HCS do not expect to retire earlier but preferred to do so significantly more often. Furthermore, HCS employees are more likely to face physically burdensome working conditions than in other sectors of the economy. The case studies indicated that there are very diverse and unsystematic strategies in addressing and supporting older employees. DISCUSSION: Older employees in the HCS sector are employed in much harsher working conditions than their peers in other sectors. This must be kept in mind when trying to extend their working lives. PMID- 30280240 TI - [Vertical and horizontal social inequality and motivation for early retirement]. AB - BACKGROUND: Over the course of the demographic transition with an aging and shrinking work force, work participation of older employees becomes more and more important. Earlier investigations found social groups to be different in work related and individual aspects, which were shown to be associated with motivation for early retirement. OBJECTIVE: The aim of the study was to investigate the differences between older employees from distinct social groups in the motivation and determinants for early retirement. MATERIAL AND METHODS: Within the framework of the prospective lidA cohort study ( www.lida-studie.de ) socially insured employees born in 1959 and 1965 were asked about work, health and work participation. Based on data from the 3961 participants who were employed at the time of both study waves (2011, 2014), associations between variables of horizontal (gender, migration background) and vertical (education) social inequality and motivation for early retirement were analyzed with multiple logistic regression and interaction analysis. RESULTS: There was an educational gradient regarding the motivation to retire in the expected direction. The wish to retire before the age of 65 years was less common in male than in female older employees. Employees with a lower level of education and with a first generation migration background wished to retire early significantly less frequently than those without a migration background. Besides the interaction between migration background and education there were no further significant moderating effects of work-related or non-work-related variables on the association of social variables and the wish to retire early. CONCLUSION: According to the results there are differences between social groups of older employees in the motivation to retire early. The reasons and the final realization still have to be investigated. As a result, consequences for companies and politics with respect to the preservation of the work force can arise. PMID- 30280241 TI - Immunobiosis and probiosis: antimicrobial activity of lactic acid bacteria with a focus on their antiviral and antifungal properties. AB - Lactic acid bacteria (LAB), a heterogeneous group of bacteria that produce lactic acid as the main product of carbohydrate degradation, play an important role in the production and protection of fermented foods. Moreover, beside the technological use of these microorganisms added to control and steer food fermentations, their beneficial healthy properties are largely overt. Thus, numerous LAB strains have obtained the probiotic status, which entails the ability to maintain and promote a good health of consumers. In particular, increasing consideration is being focused on probiotic microorganisms that can improve the human immune response against dangerous viral and fungal enemies. For such beneficial microbes, the term "immunobiotics" has been coined. Together with an indirect host-mediated adverse effect against undesirable microorganisms, also a direct antagonistic activity of several LAB strains has been largely demonstrated. The purpose of this review is to provide a fullest possible overview of the antiviral and antifungal activities ascribed to probiotic LAB. The interest in this research field is substantiated by a large number of studies exploring the potential application of these beneficial microorganisms both as biopreservatives and immune-enhancers, aiming to reduce and/or eliminate the use of chemical agents to prevent the development of pathogenic, infectious, and/or degrading causes.

AB - Iron accumulates in the lungs of patients with common respiratory diseases or transfusion-dependent beta-thalassemia. Based on our previous work, we hypothesized that systemic iron overload affects the alveolar region of the lung and in particular the surfactant producing alveolar epithelial type II (AE2) cells. Mice with a point mutation in the iron exporter ferroportin, a model for human hemochromatosis type 4 were compared to wildtype mice (n = 5 each). Lungs were fixed and prepared for light and electron microscopy (EM) according to state of-the-art protocols to detect subcellular iron localization by scanning EM/EDX and to perform design-based stereology. Iron was detected as electron dense particles in membrane-bound organelles, likely lysosomes, in AE1 cells. AE2 cells were higher in number but had a lower mean volume in mutated mice. Lamellar body volume per AE2 cell was lower but total volume of lamellar bodies in the lung was comparable to wildtype mice. While the volume of alveoli was lower in mutated mice, the volume of alveolar ducts as well as the surface area, volume and the mean thickness and composition of the septa was similar in both genotypes. The thickness of the air-blood barrier was greater in the mutated than in the WT mice. In conclusion, disruption of systemic iron homeostasis affects the ultrastructure of interalveolar septa which is characterized by membrane-bound iron storage in AE1 cells, thickening of the air-blood barrier and hyperplasia and hypotrophy of AE2 cells despite normal total intracellular surfactant pools. The functional relevance of these findings requires further analysis to better understand the impact of iron on intra-alveolar surfactant function. PMID- 30280243 TI - How cancer cells attach to urinary bladder epithelium in vivo: study of the early stages of tumorigenesis in an orthotopic mouse bladder tumor model. AB - The majority of bladder cancers in humans are non-muscle-invasive cancers that recur frequently after standard treatment procedures. Mouse models are widely used to develop anti-tumor treatments. The purpose of our work was to establish an orthotopic mouse bladder tumor model and to explore early stages of implantation of cancerous MB49 cells in vivo using various labeling and microscopic techniques. To distinguish cancer cells from normal urothelial cells in mouse urinary bladders, we performed molecular characterization of MB49 cells before intravesical injection experiments. In this new approach we applied internalized metal nanoparticles to unequivocally discriminate cancer cells from normal cells. This method revealed that cancer cells attached to the urothelium or basal lamina within just 1 hour of intravesical injection, whereas small tumors and localized hyperplastic urothelial regions developed within two days. We found that cancer cells initially adhere to normal urothelial cells through filopodia and by focal contacts with basal lamina. This is the first in vivo characterization of intercellular contacts between cancerous and normal urothelial cells in the bladder. Our study yields new data about poorly known early events of tumorigenesis in vivo, which could be helpful for the translation into clinic. PMID- 30280244 TI - [Pacemaker and MRI in clinical practice]. AB - The number of cardiac pacemaker wearers is continuously increasing in Germany as well as worldwide. The probability of indications for a magnetic resonance imaging (MRI) examination during the lifetime is approximately 50-75% for every person. An MRI examination is nowadays possible for pacemaker wearers under certain conditions. Due to the technical developments during the last 10 years certain MRI-conditional pacemakers are available. The recommendations of the German and American medical specialist societies currently allow an MRI examination in patients with conventional pacemakers beyond the approval conditions (off-label use) under prespecified conditions, based on the study data. This article summarizes the information on conditions of use and reprogramming strategies as well as on the study situation for the clinical routine. PMID- 30280245 TI - Comparison of radiomics machine-learning classifiers and feature selection for differentiation of sacral chordoma and sacral giant cell tumour based on 3D computed tomography features. AB - OBJECTIVE: We aimed to identify optimal machine-learning methods for preoperative differentiation of sacral chordoma (SC) and sacral giant cell tumour (SGCT) based on 3D non-enhanced computed tomography (CT) and CT-enhanced (CTE) features. METHODS: A total of 95 patients were divided into a training set and a validation set. Three best feature selection methods (Relief, least absolute shrinkage and selection operator (LASSO) and Random Forest (RF)) and three classification methods, including generalised linear models (GLM), support vector machines (SVM) and RF, were compared for their performance in distinguishing SC and SGCT. The performance of the radiomics model was investigated via area under the receiver operating characteristic curve (AUC) and accuracy (ACC) analysis. RESULTS: The selection method LASSO + classifier GLM had the highest AUC of 0.984 and ACC of 0.897 in the validating set, followed by Relief + GLM (AUC = 0.909, ACC = 0.862) and LASSO + SVM (AUC = 0.900, ACC = 0.862) based on CTE features. For CT features, RF + GLM had the highest AUC of 0.889, while LASSO + GLM achieved a high ACC of 0.793 in the validating set. Regardless of the methods, CTE features significantly outperformed those from CT for the differentiation of SC and SGCT (ZAUC = -3.029, ZACC = -4.553; p < 0.05). CONCLUSIONS: Our study demonstrated CTE features performed better than CT features. The selection method LASSO + classifier GLM had the best performance in differentiation of SC and SGCT, which could enhance the application of radiomics methods in sacral tumours. KEY POINTS: * Sacral chordoma and sacral giant cell tumour are the two most common primary tumours of the sacrum with many common clinical and imaging characteristics. * A radiomics model helps clinicians to identify the histology of a sacral tumour. * CTE features should be preferred. PMID- 30280246 TI - Gastric cancer and imaging biomarkers: Part 1 - a critical review of DW-MRI and CE-MDCT findings. AB - : The current standard of care for gastric cancer imaging includes heterogeneity in image acquisition techniques and qualitative image interpretation. In addition to qualitative assessment, several imaging techniques, including diffusion weighted magnetic resonance imaging (DW-MRI), contrast-enhanced multidetector computed tomography (CE-MDCT), dynamic-contrast enhanced MRI and 18F fluorodeoxyglucose positron emission tomography, can allow quantitative analysis. However, so far there is no consensus regarding the application of functional imaging in the management of gastric cancer. The aim of this article is to specifically review two promising biomarkers for gastric cancer with reasonable spatial resolution: the apparent diffusion coefficient (ADC) from DW-MRI and textural features from CE-MDCT. We searched MEDLINE/ PubMed for manuscripts published from inception to 6 February 2018. Initially, we searched for (gastric cancer OR gastric tumour) AND diffusion weighted magnetic resonance imaging. Then, we searched for (gastric cancer OR gastric tumour) AND texture analysis AND computed tomography. We collated the results from the studies related to this query. There is evidence that: (1) the ADC is a promising biomarker for the evaluation of the aggressiveness (T and N stage), treatment response and prognosis of gastric cancer; (2) textural features are related to the degree of differentiation, Lauren classification, treatment response and prognosis of gastric cancer. We conclude that these imaging biomarkers hold promise as effective additional tools in the diagnostic pathway of gastric cancer and may facilitate the multidisciplinary work between the radiologist and clinician, and across different institutions, to provide a greater biological understanding of gastric cancer. KEY POINTS: * Quantitative imaging is the extraction of quantifiable features from medical images for the assessment of normal or pathological conditions and represents a promising area for gastric cancer. * Quantitative analysis from CE-MDCT and DW-MRI allows the extrapolation of multiple imaging biomarkers. * ADC from DW-MRI and CE- MDCT-based texture features are non-invasive, quantitative imaging biomarkers that hold promise in the evaluation of the aggressiveness, treatment response and prognosis of gastric cancer. PMID- 30280247 TI - Ultra-high-field arterial spin labelling MRI for non-contrast assessment of cortical lesion perfusion in multiple sclerosis. AB - OBJECTIVES: To assess the feasibility of using an optimised ultra-high-field high spatial-resolution low-distortion arterial spin labelling (ASL) MRI acquisition to measure focal haemodynamic pathology in cortical lesions (CLs) in multiple sclerosis (MS). METHODS: Twelve MS patients (eight female, mean age 50 years; range 35-64 years) gave informed consent and were scanned on a 7 Tesla Philips Achieva scanner. Perfusion data were collected at multiple post-labelling delay times using a single-slice flow-sensitive alternating inversion recovery ASL protocol with a balanced steady-state free precession readout scheme. CLs were identified using a high-resolution Phase-Sensitive Inversion Recovery (PSIR) scan. Significant differences in perfusion within CLs compared to immediately surrounding normal appearing grey matter (NAGMlocal) and total cortical normal appearing grey matter (NAGMcortical) were assessed using paired t-tests. RESULTS: Forty CLs were identified in PSIR scans that overlapped with the ASL acquisition coverage. After excluding lesions due to small size or intravascular contamination, 27 lesions were eligible for analysis. Mean perfusion was 40 +/- 25 ml/100 g/min in CLs, 53 +/- 12 ml/100 g/min in NAGMlocal, and 53 +/- 8 ml/100 g/min in NAGMcortical. CL perfusion was significantly reduced by 23 +/- 9% (mean +/- SE, p = 0.013) and 26 +/- 9% (p = 0.006) relative to NAGMlocal and NAGMcortical perfusion, respectively. CONCLUSION: This is the first ASL MRI study quantifying CL perfusion in MS at 7 Tesla, demonstrating that an optimised ASL acquisition is sensitive to focal haemodynamic pathology previously observed using dynamic susceptibility contrast MRI. ASL requires no exogenous contrast agent, making it a more appropriate tool to monitor longitudinal perfusion changes in MS, providing a new window to study lesion development. KEY POINTS: * Perfusion can be quantified within cortical lesions in multiple sclerosis using an optimised high spatial resolution arterial spin Labelling MRI acquisition at ultra-high-field. * The majority of cortical lesions assessed using arterial spin labelling are hypo-perfused compared to normal appearing grey matter, in agreement with dynamic susceptibility contrast MRI literature. * Arterial spin labelling MRI, which does not involve the injection of a contrast agent, is a safe and appropriate technique for repeat scanning of an individual patient. PMID- 30280248 TI - Pelvic MRI after induction chemotherapy and before long-course chemoradiation therapy for rectal cancer: What are the imaging findings? AB - OBJECTIVES: To determine the appearance of rectal cancer on MRI after oxaliplatin based chemotherapy (ICT) and make a preliminary assessment of MRI's value in predicting response to total neoadjuvant treatment (TNT). METHODS: In this IRB approved, HIPAA-compliant, retrospective study between 1 January 2010-20 October 2014, pre- and post-ICT tumour T2 volume, relative T2 signal intensity (rT2SI), node size, signal intensity and border characteristics were assessed in 63 patients (65 tumours) by three readers. The strength of association between the reference standard of histopathological percent tumour response and tumour volume change, rT2SI and lymph node characteristics was assessed with Spearman's correlation coefficient and Wilcoxon's rank sum test. Cox regression was used to assess association between DFS and radiological measures. RESULTS: Change in T2 volume was not associated with TNT response. Change in rT2SI showed correlation with TNT response for one reader only using selective regions of interest (ROIs) and borderline correlation with response using total volume ROI. There was a significant negative correlation between baseline and post-ICT node size and TNT response (r = -0.25, p = 0.05; r = -0.35, p = 0.005, readers 1 and 2, respectively). Both baseline and post-induction median node sizes were significantly smaller in complete responders (p = 0.03, 0.001; readers 1 and 2, respectively). Change in largest baseline node size and decrease in post-ICT node signal heterogeneity were associated with 100% tumour response (p = 0.04). Nodal sizes at baseline and post-ICT MRI correlated with DFS. CONCLUSION: In patients undergoing post-ICT MRI, tumour volume did not correlate with TNT response, but decreased lymph node sizes were significantly associated with complete response to TNT as well as DFS. Relative T2SI showed borderline correlation with TNT response. KEY POINTS: * MRI-based tumour volume after induction chemotherapy and before chemoradiotherapy did not correlate with overall tumour response at the end of all treatment. * Lymph node size after induction chemotherapy and before chemoradiotherapy was strongly associated with complete pathological response after all treatment. * Lymph node sizes at baseline and post-induction chemotherapy MRI correlated with disease-free survival. PMID- 30280249 TI - Impact of image reconstruction methods on quantitative accuracy and variability of FDG-PET volumetric and textural measures in solid tumors. AB - OBJECTIVE: This study aims to assess the impact of different image reconstruction methods on PET/CT quantitative volumetric and textural parameters and the inter reconstruction variability of these measurements. METHODS: A total of 25 oncology patients with 65 lesions (between 2017 and 2018) and a phantom with signal-to background ratios (SBR) of 2 and 4 were included. All images were retrospectively reconstructed using OSEM, PSF only, TOF only, and TOFPSF with 3-, 5-, and 6.4-mm Gaussian filters. The metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were measured. The relative percent error (DeltaMTV and DeltaTLG) with respect to true values, volume recovery coefficients, and Dice similarity coefficient, as well as inter-reconstruction variabilities were quantified and assessed. In clinical scans, textural features (coefficient of variation, skewness, and kurtosis) were determined. RESULTS: Among reconstruction methods, mean DeltaMTV differed by -163.5 +/- 14.1% to 6.3 +/- 6.2% at SBR2 and -42.7 +/- 36.7% to 8.6 +/- 3.1 at SBR4. Dice similarity coefficient significantly increased by increasing SBR from 2 to 4, ranging from 25.7 to 83.4% between reconstruction methods. Mean DeltaTLG was -12.0 +/- 1.7 for diameters > 17 mm and -17.8 +/- 7.8 for diameters <= 17 mm at SBR4. It was -31.7 +/- 4.3 for diameters > 17 mm and 14.2 +/- 5.8 for diameters <= 17 mm at SBR2. Textural features were prone to variations by reconstruction methods (p < 0.05). CONCLUSIONS: Inter reconstruction variability was significantly affected by the target size, SBR, and cut-off threshold value. In small tumors, inter-reconstruction variability was noteworthy, and quantitative parameters were strongly affected. TOFPSF reconstruction with small filter size produced greater improvements in performance and accuracy in quantitative PET/CT imaging. KEY POINTS: * Quantitative volumetric PET evaluation is critical for the analysis of tumors. * However, volumetric and textural evaluation is prone to important variations according to different image reconstruction settings. * TOFPSF reconstruction with small filter size improves quantitative analysis. PMID- 30280250 TI - Meniscal body extrusion and cartilage coverage in middle-aged and elderly without radiographic knee osteoarthritis. AB - OBJECTIVES: To determine meniscal extrusion and cartilage coverage on magnetic resonance (MR) images and factors associated with these parameters in knees of middle-aged and elderly persons free from radiographic tibiofemoral osteoarthritis (OA). METHODS: Seven hundred eighteen persons, free of radiographic tibiofemoral OA, aged 50-90 years from Framingham, MA, USA, were included. We measured meniscal extrusion on 1.5 T MRI of both knees to evaluate both medial and lateral meniscal body extrusion and cartilage coverage. We also determined meniscal morphology and structural integrity. The multivariable association with age, body mass index (BMI), and ipsilateral meniscal damage was also evaluated. RESULTS: The mean meniscal body extrusion medially was 2.7 mm and laterally 1.8 mm. The tibial cartilage coverage was about 30% of ipsilateral cartilage surface (both compartments). The presence of ipsilateral meniscal damage was associated with more extrusion in only the medial compartment, 1.0 mm in men and 0.6 mm in women, and less cartilage coverage proportion, -5.5% in men and -4.6% in women. CONCLUSIONS: Mean medial meniscal body extrusion in middle aged or older persons without radiographic tibiofemoral OA approximates the commonly used cutoff (3 mm) to denote pathological extrusion. Medial meniscal damage is a factor associated with medial meniscal body extrusion and less cartilage coverage. KEY POINTS: * Medial meniscal extrusion in middle-aged/older persons without OA is around 3 mm. * Lateral meniscal extrusion in middle aged/older persons without OA is around 2 mm. * Meniscal damage is associated with medial meniscal extrusion and less cartilage coverage. PMID- 30280251 TI - Did cis- and trans-defensins derive from a common ancestor? AB - Defensins are small, cysteine-rich, cationic antimicrobial peptides, serving as effectors of the innate immune system and modulators of the adaptive immune system. They extensively exist in multicellular organisms and are divided into cis and trans according to their disulfide bridge connectivity patterns. It has been proposed that these two types of defensins convergently originated from different ancestors. Here, we report the discovery of a structural signature involved in the formation of the cysteine-stabilized alpha-helix/beta-sheet (CSalphabeta) fold of the cis-defensins in some trans-beta-defensins, with only one amino acid indel (CXC vs. CC. C, cysteine; X, any amino acid). The indel of the X residue in the structural signature provides a possible explanation as to why cis- and trans-defensins possess different folds and connectivity patterns of disulfide bridges formed in evolution. Although our attempt to convert the structure type of a present-day trans-defensin with the X residue deleted was unsuccessful due to the low solubility of the synthetic peptide, a combination of data from structural signature, function, and phylogenetic distribution suggests that these defensins may have descended from a common ancestor. In this evolutionary scenario, we propose that a progenitor cis-scaffold might gradually evolve into a trans-defensin after deleting the X residue in specific lineages. This proposal adds a new dimension to more deeply studying the evolutionary relationship of defensins with different folds and of other distantly related proteins. PMID- 30280252 TI - Trends and outcomes of sphincter-preserving surgery for rectal cancer: a national cancer database study. AB - PURPOSE: Previous studies have shown that sphincter-preserving surgery is associated with better quality of life in postsurgical rectal cancer patients. However, the factors predicting the likelihood of undergoing sphincter-preserving surgery have not been well-described. The aim of this study was to report the factors that determined the likelihood of undergoing sphincter-preserving surgery. METHODS: Characteristics of 24,018 rectal cancer patients undergoing sphincter-preserving surgery and abdominoperineal resection diagnosed from 2008 to 2012 from the National Cancer Database were investigated retrospectively for rate, pattern, and differences in mortality. Cox proportional hazards models were used to calculate hazard ratios for assessing mortality. Odds ratios were calculated using logistic regressions models for outcome sphincter-preserving surgery. RESULTS: Eighteen thousand four hundred fifty-two (77%) patients had sphincter-preserving surgery. Majority of sphincter-preserving surgery patients were aged < 70 (74%), had private insurance (52%), and got treatment at a comprehensive community cancer program (54%). Multivariable analysis showed that patients with age >= 70 (OR 0.87, 95% CI 0.80-0.95), male gender (OR 0.90, 95% CI 0.84-0.96), having Medicare (OR 0.83, 95% CI 0.76-0.90), Medicaid (OR 0.72, 95% CI 0.63-0.81), and poorly differentiated grade (OR 0.78, 95% CI 0.71-0.85) were less likely to undergo sphincter-preserving surgery. Multivariable analysis showed that patients having abdominoperineal resection have higher likelihood of mortality than sphincter-preserving surgery (HR 1.26, 95% CI 1.16-1.36). CONCLUSIONS: We were able to identify several patient and tumor-related factors impacting the likelihood of undergoing sphincter-preserving surgery. Patients undergoing non-sphincter sparing surgery had a higher mortality that sphincter preservation. PMID- 30280253 TI - Starry-sky bowels. AB - PURPOSE: Because of the increasing usage of lanthanum carbonate in dialysis patients, clinicians should be aware of its typical radiographic appearance. METHODS: A dialysis patient received a plain film and a computed tomography, both showing a "starry-sky" appearance in the nearly whole colon, and the radiological report mistakenly denoted it as barium. RESULTS: The patient denied any exposure to barium or radiocontrast medium. Tracing back her medication history, lanthanum carbonate, 500 mg twice a day, has been prescribed for her hyperphosphatemia in recent 5 months. CONCLUSIONS: Clinicians should be aware of typical radiographic appearance of lanthanum carbonate to avoid unnecessary management and may also take its radiopaque characteristic as an advantage to assess the patient's drug adherence. PMID- 30280254 TI - Feature Extraction Using Dominant Local Texture-Color Patterns (DLTCP) and Classification of Color Images. AB - Feature extraction and classification are considered to be the major tasks in image processing applications. This paper proposes a novel method to extract the features of a color image for classification. The proposed method, Dominant Local Texture-Color Patterns (DLTCP) is based on the Dominant Texture and Dominant Color channels in a RGB color space. The dominant texture pattern represents a channel among RGB with maximum variations in the texture and the dominant color pattern represents the color channel with the maximum pixel intensity. The combination of channels with dominant texture pattern and dominant color pattern is assigned a unique value which is used to extract the features of an image. The proposed texture-color features is tested for rotational, illumination and scale invariance property using the color images taken from Outex and Vistex databases. It is experimentally shown that the proposed method achieves the highest accuracy in classification using K-Nearest Neighbor (KNN) classifier under various challenges.

PMID- 30280256 TI - A comparison of the effects of selected mono-ethnic urban environments on the autonomic functions of Muslim and Jewish women in Israel. AB - Few previous studies evaluated ethnic differences in the effects of urban environments on the autonomic balance in intra-ethnic environments and the mediation effects of environmental exposures (air pollution, noise, and thermal load). In a field experimental study, we exposed 48 Muslim and 24 Jewish women to park, town center, and residential street in Israeli mono-ethnic small towns. Heart rate variability (HRV), noise, thermal load, and carbon monoxide (CO) were measured by portable devices while visiting the environments and were analyzed using mixed models. The results highlight the restorative effect of parks on both ethnic groups with stronger effect for Jewish women compared to Muslim women (beta coefficient (95% confidence interval (CI)): - 6.45(- 6.70, - 6.20); - 4.99 (- 5.15, - 4.83), respectively). However, significant differences were recorded in Muslim and Jewish coping with the environments and the environmental exposures as measured by HRV. PMID- 30280257 TI - The difference of stress distribution of maxillary expansion using rapid maxillary expander (RME) and maxillary skeletal expander (MSE)-a finite element analysis. AB - BACKGROUND: Maxillary skeletal expander (MSE) in combination with miniscrews was developed to overcome the drawbacks that may have resulted from the application of conventional rapid maxillary expander (RME). This research was conducted to analyze the difference of stress distribution of maxillary expansion using RME and MSE in the region of interests (ROIs): first molars (M1), palatal alveolar bones of M1, palatine sutures, zygomatic sutures, miniscrews, and their surrounding bones. METHODS: A dry skull was scanned using CBCT and rendered into a three-dimensional (3D) model of craniomaxillary structures. The data analysis was done both visually and numerically. RESULT: The stress distributions in RME group were located at the palatal side of M1, mesial side of palatal alveolar of M1, pulp chamber of M1, and inferior cortex of palatine sutures. The stress distributions in the MSE group were located at the distopalatal cusp of M1, palatal side of palatal alveolar of M1, and inferior and superior cortex of palatine sutures. The stress distributions in zygomatic sutures on both groups were located at the zygomaticotemporal sutures, whereas in the miniscrews, the stress were located at the anterior miniscrews and palatal side of surrounding bones. CONCLUSIONS: There were significant differences of stress distribution of maxillary expansion measured in the ROIs in the craniomaxillary 3D model using RME and MSE.

PMID- 30280260 TI - Earlier detection of Alzheimer disease using N-fold cross validation approach. AB - According to the recent study, world-wide 40 million patients are affected by Alzheimer disease (AD) because it is one of the dangerous neurodegenerative disorders. This AD disease has less symptoms such as short term memory loss, mood swings, problem with language understanding and behavioral issues. Due to these low symptoms, AD disease is difficult to recognize in the early stage. So, the automated computer aided system need to be developed for recognizing the AD disease for minimizing the mortality rate. Initially, brain MRI image is collected from patients which are processed by applying different processing steps such as noise removal, segmentation, feature extraction, feature selection and classification. The captured MRI image has noise that is eliminated by applying the Lucy-Richardson approach which examines the each pixel in the image and removes the Gaussian noise which also eliminates the blur image. After eliminating the noise pixel from the image, affected region is segmented by Prolong adaptive exclusive analytical Atlas approach. From the segmented region, different GLCM statistical features are extracted and optimal features subset is selected by applying the hybrid wrapper filtering approach. This selected features are analyzed by N-fold cross validation approach which recognizes the AD related features successfully. Then the efficiency of the system is evaluated with the help of MATLAB based experimental results, in which Alzheimer's Disease Neuroimaging Initiative (ADNI) dataset images are utilized for examining the efficiency in terms of sensitivity, specificity, ROC curve and accuracy. PMID- 30280258 TI - Colorimetric adenosine aptasensor based on DNA cycling amplification and salt induced aggregation of gold nanoparticles. AB - An aptamer based assay is described for the colorimetric detection of adenosine. The presence of adenosine triggers the deformation of hairpin DNA oligonucleotide (HP1) containing adenosine aptamer and then hybridizes another unlabeled hairpin DNA oligonucleotide (HP2). This leads to the formation of a double strand with a blunt 3' terminal. After exonuclease III (Exo III)-assisted degradation, the guanine-rich strand (GRS) is released from HP2. Hence, the adenosine-HP1 complex is released to the solution where it can hybridize another HP2 and initiate many cycles of the digestion reaction with the assistance of Exo III. This leads to the generation of a large number of GRS strands after multiple cycles. The GRS stabilize the red AuNPs against aggregation in the presence of potassium ions. If, however, GRS forms a G-quadruplex, it loses its ability to protect gold nanoparticles (AuNPs) from salt-induced AuNP aggregation. Therefore, the color of the solution changes from red to blue which can be visually observed. This colorimetric assay has a 0.13 nM detection limit and a wide linear range that extends from 5 nM to 1 MUM.

PMID- 30280262 TI - Population Pharmacokinetics and Exposure-Response Relationships of Naldemedine. AB - PURPOSE: To characterize population pharmacokinetic (PK) of naldemedine, to identify factors which influence naldemedine PK, and to evaluate their clinical relevancy based on exposure-response relationships. METHODS: A population PK model was developed with pooled naldemedine concentrations from healthy subjects, patients with chronic non-cancer pain and opioid-induced constipation (OIC), and cancer patients with OIC. Exposure-response analyses were performed with efficacy (responder or non-responder) and safety (occurrence of gastrointestinal disorders or not) data in phase 2b and phase 3 studies. RESULTS: Naldemedine plasma concentrations were adequately described by a 2-compartment model with first order absorption and absorption lag time. The final model included the effects of age, creatinine clearance, race, and gender on apparent total clearance; the effects of body weight, health status, and food condition on apparent volume of central compartment; and the effect of age on first-order rate of absorption. When subjects took 0.2 mg of naldemedine once daily, the probability of spontaneous bowel movement (SBM) responders was predicted to be approximately 50%, while that of severe gastrointestinal disorders was predicted to be less than 3%. The influence of the covariates on PK was not considered clinically significant because similar efficacy and safety were expected based on the exposure-response analysis. CONCLUSIONS: The covariates are identified in the population PK analysis; however, no dose-adjustment is required for them based on the exposure-response analysis. PMID- 30280261 TI - Septic Encephalopathy. AB - PURPOSE OF THE REVIEW: To discuss the diagnostic approach to patients with septic encephalopathy as well as the need for specific neuro-monitoring and the perspectives on future therapeutic approaches in this setting. RECENT FINDINGS: Most of data-concern experimental studies evaluating the pathophysiology of septic encephalopathy. A combination of neurodegenerative pathways with neurovascular injury is the cornerstone for the development of such complication and the long-term neurological sequelae among survivors. Septic encephalopathy is a common complication in septic patients. Clinical presentation may range from mild confusion and disorientation to convulsions and deep coma. The diagnosis of septic encephalopathy is made difficult by the lack of any specific clinical and non-clinical feature, in particular among sedated patients in whom neurological examination is unreliable. In spite of the high mortality rate associated with this condition, there is no prophylactic or targeted therapy to reduce or minimize brain damage in septic patients and clinical management is limited to the treatment of the underlying infection.

In medical images due to presence of white foreground and black background, many pixels have intensities similar to impulse noise and hence the distinction between noisy and regular pixels is difficult. Therefore, it is important to design a method to accurately remove this type of noise. In addition to the accuracy, the complexity of the method is very important in terms of hardware implementation. In this paper a low complexity de-noising method is proposed that distinguishes between noisy and non-noisy pixels and removes the noise by local analysis of the image blocks. All steps are designed to have low hardware complexity. Simulation results show that in the case of magnetic resonance images, the proposed method removes impulse noise with an acceptable accuracy. PMID- 30280263 TI - Privacy-Preserving and Efficient Truly Three-Factor Authentication Scheme for Telecare Medical Information Systems. AB - Significant development of information technologies has made Telecare Medical Information Systems (TMISs) increasingly popular. In a TMIS, patients upload their medical data through smart devices to obtain a doctor's diagnosis. However, these smart devices have limited computing and storage capacities, so it is difficult to store substantial patient information and to support time-consuming operations. Moreover, although many three-factor authentication protocols have been proposed for TMISs, the problems of privacy leaks and other security flaws are serious. In addition, authentication factors are verified at the user side in most protocols, giving users a high level of trust and resulting in a potential lack of security. In this paper, we propose a novel efficient truly three-factor authentication protocol for TMISs. In our proposed protocol, three factors (i.e., password, smart card and biometrics) are verified at the server side, which reduces the storage and computational burden of the user side. Additionally, our proposed protocol uses only lightweight operators and is thus efficient. A formal proof analysis demonstrates that our proposed protocol is provably secure in the random oracle model. The performance evaluation shows that the proposed protocol is very efficient and suitable for TMISs. PMID- 30280265 TI - The easy-to-hard training advantage with real-world medical images. AB - Many medical professions require practitioners to perform visual categorizations in domains such as radiology, dermatology, and neurology. However, acquiring visual expertise is tedious and time-consuming and the perceptual strategies mediating visual categorization skills are poorly understood. In this paper, the Ease algorithm was developed to predict an item's categorization difficulty (Ease value) based on the item's perceptual similarity to all within-category items versus between-category items in the dataset. In this study, Ease values were used to construct an easy-to-hard and hard-to-easy training schedule for teaching melanoma diagnosis. Whereas previous visual training studies suggest that an easy to-hard schedule benefits learning outcomes, no studies to date have demonstrated the easy-to-hard advantage with complex, real-world images. In our study, 237 melanoma and benign images were collected for training and testing purposes. The diagnostic accuracy of images was verified by an expert dermatologist. Based on their Ease values, the items were grouped into easy, medium, and hard categories, each containing an equal number of melanoma and benign lesions. During training, participants categorized images of skin lesions as either benign or melanoma and were given corrective feedback after each trial. In the easy-to-hard training condition, participants learned to categorize all the easy items first, followed by the medium items, and finally the hard items. Participants in the hard-to-easy training condition learned items in the reverse order. Post-training results showed that training in both conditions transferred to the classification of new melanoma and benign images. Participants in the easy-to-hard condition showed modest advantages both in the acquisition and retention of the melanoma diagnosis skills, but neither scheduling condition exhibited a gross advantage. The Ease values of the items predicted categorization accuracy after, but not before training, suggesting that the Ease algorithm is a promising tool for optimizing medical training in visual categorization. PMID- 30280266 TI - Theoretical design of novel energetic salts derived from bicyclo-HMX. AB - We designed three novel cage energetic anions by introducing ionic bridges containing NTheta, N(OTheta) and N(NThetaNO2) into cis-2,4,6,8-tetranitro-1H,5H 2,4,6,8- tetraazabicyclo[3.3.0] octane (bicyclo-HMX or BCMHX). The properties of 21 energetic salts, based on cage anions and ammonium-based cations, were studied by density functional theory (DFT) and volume-based thermodynamics (VBT) calculations. Compared to the parent nonionic BCHMX, most title salts have lower predicted impact sensitivities, higher predicted densities, larger predicted heats of formation (HOFs) and better predicted detonation properties. In particular, 11 energetic salts not only exhibit excellent predicted energetic properties, superior to 2,4,6,8,10,12-hexanitrohexaazaisowurtzitane (CL-20), but also have lower predicted sensitivity than CL-20. The best salt had a predicted detonation velocity of 10.06 km s-1, a predicted detonation pressure of 48.54 GPa and a predicted sensitivity (h50) of 23.99 cm. By introducing ionic bridges into highly nitrated rings, or modifying the original bridge with ionic bridges, some highly nitrated cage compounds with both excellent performance and low sensitivity can be developed strategically.

PMID- 30280268 TI - Lanthanide doped carbon dots as a fluorescence chromaticity-based pH probe. AB - A colorimetric and fluorescent pH probe was designed by doping carbon dots (C dots) with Eu(III), Tb(III) and 2,6-pyridinedicarboxylic acid (DPA). The resulting nanoparticles were applied as fluorescent indicators for pH values (best detected at excitation/emission wavelengths of 272/545, 614 nm). The pH induced optical effects are due to pH induced variations in energy transfer. The fluorescence of the probe shows a continuous color variation, and a linear change with pH values in the range from 3.0 to 10.0 can be established by using a Commission Internationale de L'Eclairage (CIE) chromaticity diagram. This new kind of pH nanoprobe is more accurate than previously reported pH indicator probes because the pH value can be calculated by using chromaticity coordinates that only depend on the chromaticity. The pH nanoprobe was applied to visualize pH values in human breast adenocarcinoma cells (MCF-7). Graphical abstract Carbon dots modified with Eu(III) and Tb(III) complexes of 2,6-pyridinedicarboxylic acid (DPA) were prepared. The doped carbon dots were used as a pH-sensitive nanosensor. The fluorescence chromaticity of the nanoparticles changes with the variation of pH value. PMID- 30280267 TI - Longitudinal Progression Markers of Parkinson's Disease: Current View on Structural Imaging. AB - PURPOSE OF REVIEW: Advances in neuroimaging techniques pave a rich avenue for in vivo progression biomarkers, which can objectively and noninvasively assess the long-term dynamic alterations in the brain of Parkinson's disease (PD) patients. This article reviews recent progress in structural magnetic resonance imaging (MRI) tools to track disease progression in PD, and discusses specific criteria a neuroimaging tool needs to meet to be a progression biomarker of PD and the potential applications of these techniques in PD based on current evidence. RECENT FINDINGS: Recent longitudinal studies showed that quantitative structural MRI markers derived from T1-weighted, diffusion-weighted, neuromelanin-sensitive, and iron-sensitive imaging have the potential to track disease progression in PD. However, validation of these progression biomarkers is only beginning, and more work is required for multisite validation, the sample size for use in a clinical trial, and drug-responsiveness of most of these biomarkers. At present, the most clinical trial-ready biomarker is free-water diffusion imaging of the substantia nigra and seems well established to be used in disease-modifying studies in PD. A variety of structural imaging biomarkers are promising candidates to be progression biomarkers in PD. Further studies are needed to elucidate the sensitivity, reliability, sample size, and effect of confounding factors of these progression biomarkers. PMID- 30280269 TI - Compression of CT Images using Contextual Vector Quantization with Simulated Annealing for Telemedicine Application. AB - The role of compression is vital in telemedicine for the storage and transmission of medical images. This work is based on Contextual Vector Quantization (CVQ) compression algorithm with codebook optimization by Simulated Annealing (SA) for the compression of CT images. The region of interest (foreground) and background are separated initially by region growing algorithm. The region of interest is encoded with low compression ratio and high bit rate; the background region is encoded with high compression ratio and low bit rate. The codebook generated from foreground and background is merged, optimized by simulated annealing algorithm. The performance of CVQ-SA algorithm was validated in terms of metrics like Peak to Signal Noise Ratio (PSNR), Mean Square Error (MSE) and Compression Ratio (CR), the result was superior when compared with classical VQ, CVQ, JPEG lossless and JPEG lossy algorithms. The algorithms are developed in Matlab 2010a and tested on real-time abdomen CT datasets. The quality of reconstructed image was also validated by metrics like Structural Content (SC), Normalized Absolute Error (NAE), Normalized Cross Correlation (NCC) and statistical analysis was performed by Mann Whitney U Test. The outcome of this work will be an aid in the field of telemedicine for the transfer of medical images. PMID- 30280270 TI - Epigenetics Variation and Pathogenesis in Diabetes. AB - PURPOSE OF REVIEW: Great strides have recently been made in elucidating the role of genetic sequence variation in diabetes pathogenesis. Increasingly, studies are focusing on other factors that may contribute to the pathogenesis of diabetes, such as epigenetics, a term "traditionally" encompassing changes to the DNA that do not alter sequence and are heritable (primary methylation and histone modification) but often expanded to include microRNAs. This review summarizes latest findings on the role of epigenetics in diabetes pathogenesis. RECENT FINDINGS: Recent studies illustrate roles for methylation changes, histone modification, imprinting, and microRNAs across several diabetes types and complications. Notably, methylation changes in the human leukocyte antigen (HLA) region have been found to precede the development of type 1 diabetes. In type 2 diabetes, lifestyle factors appear to interact with epigenetic mechanisms in pathogenesis. Emerging technologies have allowed increasingly comprehensive descriptive analysis of the role of epigenetic mechanisms in diabetes pathogenesis which have yielded meaningful insights into effects on expression of relevant genes. These findings have the potential to inform future development of predictive testing to enable primary prevention and further work to uncover the complex pathogenesis of diabetes. PMID- 30280271 TI - A Novel Enhanced Gray Scale Adaptive Method for Prediction of Breast Cancer. AB - Breast cancer is the important problem across the globe in which, most of the women are suffering without knowing the causes and effects of the cancer cells. Mammographic is the most powerful tool for the diagnosis of the Breast cancer. The analysis of this mammogram images proves to be more vital in terms of diagnosis but the accuracy level still needs improvisation. Several intelligent techniques are suggested for the detection of Microcalcification, Clusters, Masses, Spiculate lesions, Asymmetry and Architectural distortions in the mammograms. But the prediction of the cancer levels needs more research light. For the determination of the higher level of accuracy and prediction, the proposed algorithm called Enhanced Gray Scale Adaptive Method (EGAM) which works on the principle of combination of K-GLCM and Extreme Fuzzy Learning Machines (EFLM). The proposed algorithm has achieved 99% accuracy and less computation time in terms of classification, detection and prediction when compared with the existing intelligent algorithms. PMID- 30280272 TI - Origin and distribution of nitrate in water well of settlement areas in Yogyakarta, Indonesia. AB - Pollution of nitrate in water wells in Yogyakarta City was reported to increase for two decades. This study aimed to describe nitrate contamination in the water wells of colorectal cancer (CRC) and inflammatory bowel disease (IBD) patients, previously described elsewhere. Nitrate and chloride content of 150 water samples from the wells of patients with CRC and IBD who were residing in Yogyakarta, Sleman, or Bantul districts were examined. Description of nitrate contamination was presented in the form of box plot charts and map. Kruskal-Wallis analysis was used to measure the difference of nitrate concentration in three areas of study. Comparisons of nitrate and chloride concentrations were used to determine the source of nitrate contamination in water well. Fisher's exact test was used to describe the relationship of well distance with the septic tank to nitrate concentration in water well. The wells in Yogyakarta City had the highest median nitrate content compared to Sleman and Bantul (P = 0.001) with the median of 56.6, 13.1, and 7.7 for Yogyakarta, Sleman, and Bantul, respectively, and most tested samples exceed WHO safe drinking water standards. The spread of nitrate contamination has occurred in areas adjacent to Yogyakarta City compared to the previous report. The ratio of nitrate to chloride (1-8:1) suggested that the source of nitrate contamination in water wells in the study area came from feces due to inadequate on-site sanitation. The mapping showed nitrate contamination in water wells in Yogyakarta City, Sleman, and Bantul districts had spread according to urban development. PMID- 30280274 TI - Ketosis-Prone Diabetes (Flatbush Diabetes): an Emerging Worldwide Clinically Important Entity. AB - PURPOSE OF REVIEW: Ketosis-prone diabetes or Flatbush diabetes has been widely recognized as a clinical entity since 1984. Most of the early clinical studies focused on African American or Afro-Caribbean individuals. It is now being recognized as an important clinical entity in sub-Saharan Africans, Asian and Indian populations, and Hispanic populations. Major questions remain as to its pathogenesis and whether it is a unique type of diabetes or a subset of more severe type 2 diabetes with greater loss of insulin action in target tissues. This review summarizes the main clinical and mechanistic studies to improve the understanding of ketosis-prone (Flatbush) diabetes. RECENT FINDINGS: Little data are available on the magnitude of KPD in the different susceptible populations. It is relatively common in black populations. KPD is defined as a syndrome in which diabetes commences with ketoacidosis in individuals who are GAD and anti islet cell antibody negative and have no known precipitating causes. The patients present during middle age, are overweight or mildly obese, and in many reports are more likely to be male. After intensive initial insulin therapy, many patients become insulin independent and can be well controlled on diet alone or diet plus oral medications. The clinical course of KPD is like that of patients with type 2 diabetes rather than that of type 1 diabetes. Little differences are found in the clinical characteristics and clinical outcomes between patients presenting with KPD and those presenting with severe hyperglycemia with no ketoacidosis. The mechanisms responsible for the development of ketosis-prone diabetes as well its remission remain unknown. PMID- 30280273 TI - A Cell Assay for Detecting Anti-PEG Immune Response against PEG-Modified Therapeutics. AB - PURPOSE: Immunogenicity of PEGylated proteins and nanomedicines represents a potential impediment against their development and use in clinical settings. The purpose of this study is to develop a method for detecting anti-PEG immunity of PEGylated proteins and/or nanomedicines using flow cytometry. METHODS: The binding of fluorescence-labeled mPEG-modified liposomes to HIK-G11 cells, PEG specific hybridoma cells, or spleen cells was evaluated by flow cytometry for detecting immunogenicity of PEGylated therapeutics. RESULTS: The fluorescence labeled methoxy PEG (mPEG)-modified liposomes were efficiently bound to HIK-G11 cells. Such staining with fluorescence-labeled mPEG-modified liposomes was significantly inhibited in the presence of either non-labeled mPEG-modified liposomes or mPEG-modified ovalbumin (OVA) but not polyglycerol-modified liposomes. In addition, we found that mPEG-modified liposomes, highly immunogenic, caused proliferation of PEG-specific cells, while hydroxyl PEG modified liposomes, less immunogenic, scarcely caused. Furthermore, after intravenous injection of mPEG-modified liposomes, the percentage of PEG-specific cells in the splenocytes, as determined by flow cytometry, corresponded well with the production level of anti-PEG antibodies, as determined by ELISA. CONCLUSIONS: PEG-specific B cell assay we introduced may become a useful method to detect an anti-PEG immune response against PEGylated therapeutics and clarify the mechanism for anti-PEG immune responses. PMID- 30280275 TI - Combination Metabolomics Approach for Identifying Endogenous Substrates of Carnitine/Organic Cation Transporter OCTN1. AB - PURPOSE: Solute carrier SLC22A4 encodes the carnitine/organic cation transporter OCTN1 and is associated with inflammatory bowel disease, although little is known about how this gene is linked to pathogenesis. The aim of the present study was to identify endogenous substrates that are associated with gastrointestinal inflammation. METHODS: HEK293/OCTN1 and mock cells were incubated with colon extracts isolated from dextran sodium sulfate-induced colitis mice; the subsequent cell lysates were mixed with the amino group selective reagent 3 aminopyridyl-N-hydroxysuccinimidyl carbamate (APDS), to selectively label OCTN1 substrates. Precursor ion scanning against the fragment ion of APDS was then used to identify candidate OCTN1 substrates. RESULTS: Over 10,000 peaks were detected by precursor ion scanning; m/z 342 had a higher signal in HEK293/OCTN1 compared to mock cells. This peak was detected as a divalent ion that contained four APDS derived fragments and was identified as spermine. Spermine concentration in peripheral blood mononuclear cells from octn1 gene knockout mice (octn1-/-) was significantly lower than in wild-type mice. Lipopolysaccharide-induced gene expression of inflammatory cytokines in peritoneal macrophages from octn1-/- mice was lower than in wild-type mice. CONCLUSIONS: The combination metabolomics approach can provide a novel tool to identify endogenous substrates of OCTN1. PMID- 30280276 TI - Microplastics in municipal wastewater treatment plants in Turkey: a comparison of the influent and secondary effluent concentrations. AB - Wastewater treatment plants are one of the primary pathways through which microplastics enter aquatic environments. In this study, we have determined the microplastic concentrations of the influent and secondary effluent water of two wastewater treatment plants in Turkey. For this purpose, we have taken samples of the influent and effluent water of Seyhan and Yuregir wastewater treatment facilities for 6 days in August 2017 and determined their microplastics' content both visually and using MU-Raman spectroscopy. The results showed that the influent of the wastewater treatment contained 1 million-6.5 million particles per day, while the effluent contained 220,000-1.5 million particles per day. The removal rate of microplastics was found to be between 73 and 79%. In total, seven different types of polymers were detected. The most frequently observed polymer type was polyester. PMID- 30280277 TI - Quality Comparison of Biosimilar and Copy Filgrastim Products with the Innovator Product. AB - PURPOSE: Filgrastim, a recombinant human granulocyte-colony stimulating factor, is widely used to treat congenital and acquired neutropenia. Following patent expiration of the innovator filgrastim product, biosimilar filgrastim products have been approved in the EU and shown to be comparable with the innovator with respect to quality, safety and efficacy. In less regulated markets, copy filgrastim products are available but data about their quality are scarce. In the present study, we provide a head-to-head comparative study on the quality of biosimilar and copy filgrastim products. METHODS: Innovator filgrastim product, Neupogen(r), two EU-licensed biosimilars, Zarzio(r) and Tevagrastim(r), and two copy filgrastim products, Biocilin(r) and PDgrastim(r), were subjected to peptide mapping, circular dichroism spectroscopy, fluorescence spectroscopy, sodium dodecyl sulfate polyacrylamide gel electrophoresis, high performance size exclusion chromatography, reversed-phase ultra-performance liquid chromatography, endotoxin test, flow imaging microscopy and in vitro potency assay. RESULTS: Zarzio(r) and Tevagrastim(r) have comparable quality to Neupogen(r), while Biocilin(r) showed a significantly lower and PDgrastim(r) a higher specific activity. Moreover, PDgrastim(r) showed a higher level of impurities and a lower thermo stability than the other products. CONCLUSIONS: Except for the deviating specific activities of the two copy filgrastim products, we found no substantial differences in product quality between the filgrastim products studied. PMID- 30280278 TI - Evaluation of the air pollution in a Mediterranean region by the air quality index. AB - The increasing expansion of the cities together with activities carried out on the environment by men have contributed to the deterioration of air quality. Air quality index measures how much air is free from pollution. Being aware of the healthiness of the breathed air is a right for the people. Public authorities must constantly inform the population on air quality status. Even though several pollutants are monitored by the air quality monitoring networks, providing a significant amount of data, their interpretation and presentation to the population by the public authorities is a difficult task. Some countries, for several years, have adopted evaluation procedures through daily indices that succinctly describe the air quality status in different areas of the city. The use of an index which is able to give a simple and quick information to the population represents a possible solution for the public authorities. Concerning a Mediterranean area, it has not yet been possible to adopt a single indicator to be used for informing the population. In this work, the air quality status is highlighted by the air quality index (AQI) whose purpose is to inform, in a simple and immediate way, the population. Analyzing the AQI's trend from 2013 to 2015, it was possible to assess the air quality status, obtaining an overall scenario for the purpose of protecting human health and the ecosystems. We point out that this kind of research could be applied to every region or municipality. PMID- 30280280 TI - Clinical cases and metaphysical theories of personal identity. AB - In this article, we consider three metaphysical theories of personal identity: the soul theory, the body theory, and the psychological theory. Clinical cases are discussed as they present conceptual problems for each of these theories. For the soul theory, the case of Phineas Gage, and cases of pedophilic behavior due to a brain tumor are discussed. For the body theory, hypothetical cases of cephalosomatic anastomosis and actual cases of dicephalic parapagus and craniopagus parasiticus are discussed. For the psychological theory, cases of delusions and memory impairments are discussed. After a discussion of all these cases, we conclude that it is very difficult to unequivocally favor one of these theories, yet we argue that this discussion must be based not on abstract armchair speculation, but rather, consideration of real clinical cases. PMID- 30280279 TI - Can We Re-Engineer the Endocrine Pancreas? AB - PURPOSE OF REVIEW: Engineering endocrine pancreatic tissue is an emerging topic in type 1 diabetes with the intent to overcome the current limitation of beta cell transplantation. During islet isolation, the vascularized structure and surrounding extracellular matrix (ECM) are completely disrupted. Once implanted, islets slowly engraft and mostly are lost for the initial avascular phase. This review discusses the main building blocks required to engineer the endocrine pancreas: (i) islet niche ECM, (ii) islet niche vascular network, and (iii) new available sources of endocrine cells. RECENT FINDINGS: Current approaches include the following: tissue engineering of endocrine grafts by seeding of native or synthetic ECM scaffolds with human islets, vascularization of native or synthetic ECM prior to implantation, vascular functionalization of ECM structures to enhance angiogenesis after implantation, generation of engineered animals as human organ donors, and embryonic and pluripotent stem cell-derived endocrine cells that may be encapsulated or genetically engineered to be immunotolerated. Substantial technological improvements have been made to regenerate or engineer endocrine pancreatic tissue; however, significant hurdles remain, and more research is needed to develop a technology to integrate all components of viable endocrine tissue for clinical application. PMID- 30280281 TI - Limit to steady-state aerobic power of skeletal muscles. AB - Like any other kind of cell, muscle cells produce energy by oxidizing the fuel substrate that they absorb together with the needed oxygen from the surroundings. Oxidation occurs entirely within the cell. It means that the reactants and products of reaction must at some time be dissolved in the cell's cytosol. If a cell operates at steady state, its cytosol composition remains constant. Therefore, the cytosol in a muscle that produces work at steady state must contain a constant amount of fuel, oxygen, and product of reaction dissolved in it. The greater the power produced, the higher the concentration of these solutes. There is a limit, however, to the maximum amount of solutes that the cytosol can contain without damaging the cell. General thermodynamic arguments, which are reviewed in this paper, help relate this limit to the dehydration and overhydration limits of the cell. The present analysis shows that the same limits entail a limit to the maximum power that a muscle can produce at steady state. This limit depends on the composition of the fuel mixture used by the muscle. The analysis also determines the number of fuel carbon atoms that must be oxidized in parallel within a cell to produce a given power. It may well happen that a muscle cannot reach the maximum attainable power because it cannot activate all the parallel oxidation paths that are needed to produce it. This may be due to a series of reasons ranging from health issues to a lack of training. The paper shows how the methods of indirect calorimetry can provide all the experimental data needed to determine the actual number of parallel oxidation paths that at steady state must be active in a muscle in a given exercise. A diagram relating muscle power to the number of parallel oxidation paths and fuel composition is finally presented. It provides a means to assess the power capacity of animal muscles and can be applied to evaluate their fitness, stamina, margins for improvement, and athletic potential.

PMID- 30280282 TI - Detection of lncRNA-mRNA interaction modules by integrating eQTL with weighted gene co-expression network analysis. AB - One major function of lncRNA is to regulate the expression of mRNA, but the patterns of their interactions were largely unknown. We attempted to construct lncRNA-mRNA interaction modules at a genome-wide scale. We performed a genome wide lncRNA-mRNA eQTL analysis in peripheral blood mononuclear cells of 43 individuals, followed by weighted gene co-expression network analysis and functional enrichment analysis which sought to detect functional modules. There were 4627 significant cis lnc-eQTL pairs (P < 1.4 * 10-6) and 1,587,128 significant trans lnc-eQTL pairs (P < 3.46 * 10-9). We detected 11 eQTL modules for the lnc-eQTL networks. Among them, five modules showed significant enrichments in GO terms, and three modules showed significant enrichments in specific KEGG pathways (e.g., Toll-like receptor, PI3K-Akt, NF-kappa B, and TNF signaling pathways). lncRNA-protein interaction analysis showed that some well known functional lncRNAs (HOTAIR, CCDC26, RHPN1-AS1, WT1-AS, and TCL6) in the eQTL module interacted with genes in focal adhesion and PI3K-Akt signaling pathway. We identified biologically functional lncRNA-mRNA interaction modules by integrating eQTL and weighted gene co-expression network analysis. Integrative analysis of lncRNA and mRNA data by applying eQTL analysis and weighted gene co expression network analysis methods could be helpful for functional annotation of lncRNAs. PMID- 30280284 TI - Endocrine paraneoplastic syndromes in patients with neuroendocrine neoplasms. AB - OBJECTIVE: Our aim was to assess the prevalence of endocrine paraneoplastic syndromes (EPNS) in neuroendocrine neoplasms (NENs) and estimate its impact on patient outcomes. DESIGN: This is a retrospective analysis of 834 patients with NENs (611 gastrointestinal, 166 thoracic, 57 of unknown and various other primary origin). We included 719 consecutive NEN patients treated at EKPA-Laiko Hospital, Athens, Greece and 115 patients with lung carcinoid (LC) treated at Uppsala University Hospital, Uppsala, Sweden. EPNS diagnosis was based on standard criteria. METHODS: Twenty-one patients with EPNS were detected: 16 with ectopic Cushing's syndrome (ECS), one with hypercalcaemia due to parathyroid hormone related protein (PTHrP) secretion, three with hypercalcitonaemia and one patient with dual secretion of calcitonin and beta-human chorionic gonadotropin (beta HCG). All tumours were well-differentiated; 10 patients had Stage IV disease at diagnosis. RESULTS: The prevalence of EPNS in the Greek cohort was 1.9%, whereas that of ECS among LC patients in both centres was 6.7%. Median overall survival (OS) for patients with EPNS was 160.7 months (95%CI, 86-235.4) and median event free survival (EFS) was 25.9 months (95%CI, 0-57.2). Patients presenting with EPNS prior to NEN diagnosis had longer EFS compared to patients with synchronous or metachronous EPNS (log-rank P = 0.013). Patients with ECS of extra-thoracic origin demonstrated shorter OS and EFS compared to patients with ECS of lung or thymic origin (log-rank P = 0.001 and P < 0.001, respectively). LC patients with and without ECS were comparable in 5-year and 10-year OS rates (66.7% and 33.3% versus 89.8% and 60.2%, respectively; 95%CI [189.6-300.4 months], log-rank P = 0.94) and in median EFS, 67 versus 183 months, 95%CI [50.5-207.5], log-rank P = 0.12). CONCLUSION: EPNS are relatively rare in patients with NENs and mainly concern well-differentiated tumours of the foregut. Among patients with EPNS, LC related ECS may not adversely affect patient outcomes when diagnosed prior to NEN and effectively been treated. PMID- 30280285 TI - Gallic acid activates hippocampal BDNF-Akt-mTOR signaling in chronic mild stress. AB - Gallic acid (3,4,5-trihydroxybenzoic acid) is a naturally occurring polyphenolic compound. Previous study has shown that gallic acid possessed significant antidepressant-like activity in mice, which was partly mediated by increasing serotonin and catecholamine levels. The main aim of the present study is to investigate the possible effects of gallic acid on brain-derived neurotrophic factor (BDNF) signaling activation. Mice were exposed to chronic mild stress (CMS) and orally administrated with gallic acid for four weeks. The behavioral results showed that gallic acid not only reversed the decreased sucrose preference, but also attenuated the increased immobility time. In addition, gallic acid promoted both the BDNF and p-TrkB levels in the hippocampus induced by CMS. Moreover, the results also demonstrated that the inactivated Akt-mTOR signaling pathway, as well as its downstream effectors induced by CMS was activated again by gallic acid. Last, immunofluorescence detection indicated that gallic acid reversed the newborn neurons inhibition in the dentate gyrus by CMS. In conclusion, these results show that the activation of the hippocampal BDNF-Akt mTOR signaling is involved in the antidepressant-like effects of gallic acid. PMID- 30280286 TI - A Gyrolab Assay for the Quantitation of Free Complement Protein C5a in Human Plasma. AB - Complement protein C5a is recognized as an important component of the alternative complement pathway. Its role is prominent enough to garner interest not only as a biomarker, but also as a potential therapeutic target. Bioanalytical challenges have been posed in proper quantitation of free C5a due to interference from its precursor, C5. Additionally, free therapeutic target quantitation can be difficult due to effects of sample dilution and prolonged sample incubation when therapeutic is used as capture reagent. Gyrolab technology enables quantitation of free target analyte with minimal sample dilution and rapid sample incubations, thus enabling in vitro results that are more representative of in vivo pharmacodynamics. When coupled with strategic sample pretreatment, Gyrolab offers an opportunity to quantitate free C5a in human plasma with an assay that vastly diminishes C5 interference. A Gyrolab assay for the quantitation of free C5a in human plasma was developed and validated. Validation results confirmed that proper sample pretreatment and use of the Gyrolab platform yield accurate and reliable results. Due to the advantages that it provides, Gyrolab has become our default technology of choice for quantitation of free target. PMID- 30280288 TI - Bispecific Antibodies for the Treatment of Acute Myeloid Leukemia. AB - PURPOSE OF REVIEW: Bispecific antibodies combine antigen recognition sites from two or more antibodies into a single construct allowing simultaneous binding to multiple targets. Bispecific antibodies exist which can redirect immune effector cells against acute myeloid leukemia (AML) targets. This review will highlight the progress to date and the challenges in developing bispecific antibodies for the treatment of AML. RECENT FINDINGS: Currently, a number of bispecific antibody formats including bispecific T cell engagers, dual affinity retargeting proteins, and tandem diabodies are in clinical development for AML. These antibodies target antigens present on AML blasts, including CD33, and the low affinity IL3 receptor, CD123. T cell redirecting bispecific antibodies in early phase clinical trials for AML include AG330, flotetuzumab, JNJ-63709178, and AMV564. Bispecific antibodies represent a promising immunotherapeutic approach for the treatment of cancer. The results of ongoing studies in AML will elucidate the potential for these agents in AML. PMID- 30280287 TI - Evaluation and Management of Pyogenic and Tubercular Spine Infections. AB - PURPOSE OF REVIEW: To review the most current diagnostic tools and treatment options for pyogenic and tubercular spine infection. RECENT FINDINGS: Recent studies have focused on risk factors for failed nonoperative management in order to improve patient selection. Also, spine instrumentation and different grafting options have been safely utilized in the setting of an active infection without increasing the incidence of reoccurrence. However, the optimal surgical technique has yet to be established and instead should be patient specific. Spine infections include a broad spectrum of disorders including discitis, vertebral osteomyelitis, and spinal epidural abscess. It is paramount to recognized spine infections early due to the potential catastrophic consequences of paralysis and sepsis. The management of spine infections continues to evolve as newer diagnostic tools and surgical techniques become available. Magnetic resonance imaging with contrast is the imaging study of choice and computed tomography guided biopsies are crucial for guiding antibiotic selection. Antibiotics are the mainstay of treatment and surgery is indicated in patients with neurological deficits, sepsis, spinal instability, and those who have failed nonoperative treatment. PMID- 30280289 TI - Hematopoietic Stem Cell Transplantation in the Era of Engineered Cell Therapy. AB - PURPOSE OF REVIEW: Cellular therapy using T cells modified to express chimeric antigen receptors (CAR-T cells) has had striking success in patients that have failed previous treatment for CD19+ B cell non-Hodgkin lymphoma (NHL), chronic lymphocytic leukemia (CLL), or acute lymphoblastic leukemia (ALL). Curative therapy for this group of diseases has previously been limited to allogeneic hematopoietic cell transplantation HCT (alloHCT). The recent results of CAR-T cell therapy raise the question of how best to integrate CAR-T cell therapy and alloHCT in the care of these patients. RECENT FINDINGS: Within the past 2 years, results from larger trials and increased follow-up of patients treated with CD19 CAR-T cell therapy suggest that some may achieve durable remission without transplant. The balance of efficacy and toxicity for CAR-T cell therapy and alloHCT vary by disease type, disease status at the time of treatment, patient characteristics, and the specific therapy employed. There are early signals that subsequent transplantation of patients who have achieved remission with CAR-T may be a potentially viable (though expensive) strategy.

AB - In recent years, rapid development of tissue engineering technology provides possibilities for the construction of artificial tissues or organs. In construction of engineered kidneys, researchers used native decellularized extracellular matrix (ECM) as the scaffolds to recellularization. However, thrombosis has been a great issue that hinders the progress of transplantation in vivo. In this study, heparin was immobilized to the collagen part of decellularized scaffold with collagen-binding peptide (CBP). Through the anticoagulant and endothelial cell reperfusion experiments, it can be demonstrated that the heparinized scaffolds absorbed less platelets and red blood cells which can effectively reduce the formation of thrombosis. Moreover, it is conducive to long-term adhesion of endothelial cells which is important for the formation of subsequent vascularization. Taken together, our results reveal that the whole kidney can be modified by CBP-heparin composite to reduce the thrombosis and provide the better conditions for neovascularization. PMID- 30280290 TI - Curative and palliative surgery in patients with neuroendocrine tumors of the gastro-entero-pancreatic (GEP) tract. AB - The incidence of neuroendocrine tumors (NET) increases with age. Lately, the diagnosis of NET was mainly caused by early detection of small NET (<1 cm) in the rectum and stomach, which are depicted by chance during routine and prophylactic endoscopy. Also in patients with large and metastatic pancreatic and intestinal tumors thorough pathologic investigation with use of different immunohistologic markers discovers more neuroendocrine tumors with low differentiation grade (G2 G3) and more neuroendocrine carcinomas (NEC), nowadays, than in former times. While gastric and rectal NET are discovered as small (<1 cm in diameter) and mainly highly differentiated tumors, demonstrating lymph node metastases in less than 10% of the patients, the majority of pancreatic and small bowel NET have already metastasized at the time of diagnosis. This is of clinical importance, since tumor stage and differentiation grade not only influence prognosis but also surgical procedure and may define whether a combination of surgery with systemic biologic therapy, chemotherapy or local cytoreductive procedures may be used. The indication for surgery and the preferred surgical procedure will have to consider personal risk factors of each patient (i.e. general health, additional illnesses, etc.) and tumor specific factors (i.e. tumor stage, grade of differentiation, functional activity, mass and variety of loco regional as well as distant metastases etc.). Together they define, whether radical curative or only palliative surgery can be applied. Altogether surgery is the only cure for locally advanced NET and helps to increase quality of life and overall survival in many patients with metastatic neuroendocrine tumors. The question of cure versus palliative therapy sometimes only can be answered with time, however. Many different aspects and various questions concerning the indication and extent of surgery and the best therapeutic procedure are still unanswered. Therefore, a close multidisciplinary cooperation of colleagues involved in biochemical and localization diagnostics and those active in various treatment areas is warranted to search for the optimal strategy in each individual patient. How far genetic screening impacts survival remains to be seen. Since surgeons do have a central role in the treatment of NET patients, they have to understand the need for integration into such an interdisciplinary team. PMID- 30280292 TI - Monitoring the Progression of Chronic Liver Damage in Rats Using [18F]PBR06. AB - PURPOSE: Accurate and rapid assessment of liver condition is the key to therapy for hepatitis patients. This study aim is to evaluate the peripheral benzodiazepine receptor (PBR) radioligand [18F]N-fluoroacetyl-N-(2,5 dimethoxybenzyl)-2-phenoxyaniline ([18F]PBR06) as a positron emission tomography (PET) imaging tracer of chronic liver damage in a rat model. PROCEDURES: A rat model of liver damage was made by bile duct ligation (BDL), which initiates a complex cascade of pathological events that leads to cholestasis and inflammation, eventually resulting in a severe fibrotic and severe hepatocyte injury. PET scanning, immunofluorescence staining, H&E staining, Masson's staining, and Quantitative real time polymerase chain reaction(qRT-PCR) were performed to elucidate the correlation among the expression level of PBR, radioactivity uptake, and the level of liver damage in the rat model of chronic inflammatory. RESULTS: Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TBIL) increased after BDL and peaked in 1 week, then gradually decreased over the following 3 weeks, although still higher than that of control (all P < 0.05). Histological analysis demonstrated chronic severe damage in rat livers after BDL. The uptake of [18F]PBR06 increased in livers and was correlated with severity of liver damage. Further, the mRNA level of PBR was obviously higher compared to controls. CONCLUSIONS: [18F]PBR06 can serve as a sensitive probe to monitor the progression of inflammation in liver. [18F]PBR06 imaging may be used to accurately assess liver damage degree and guide the therapeutic schedule, especially for those patients with severe liver inflammation and damage but with normal or mildly elevated serum ALT and AST. As a non-invasive diagnostic application, [18F]PBR06 PET scan could be an alternative for patients who is unwilling to perform liver biopsy. PMID- 30280293 TI - Ripor2 is involved in auditory hair cell stereociliary bundle structure and orientation. AB - RIPOR2 (previously known as FAM65B) localizes to stereocilia of auditory hair cells and causes deafness when its function is disturbed by mutations. Here, we demonstrate that during the morphogenesis of the hair cell bundle, absence of Ripor2 affects the orientation of this key subcellular structure. We show that Ripor2 interacts with Myh9, a protein encoded by a known deafness gene. Absence of Ripor2 is associated with low Myh9 abundance in the mouse cochlea despite increased amount of Myh9 transcripts. While Myh9 is mainly expressed in stereocilia, a phosphorylated form of Myh9 is particularly enriched in the kinocilium. In Ripor2-deficient mice, kinocilium shows an aberrant localization which associates with a reduced content of phosphorylated Myh9. Acetylated alpha tubulin, another specific kinociliary protein which contributes to microtubule stabilization, is reduced in the absence of Ripor2 as well. We propose that Ripor2 deficiency influences abundance and/or post-translational modifications of proteins expressed in both stereocilia and kinocilia. This effect may have a negative impact on the structure and function of the auditory hair cell bundle. PMID- 30280295 TI - Different Secretory Activity of Articular and Subcutaneous Adipose Tissues from Rheumatoid Arthritis and Osteoarthritis Patients. AB - Rheumatoid arthritis (RA) and osteoarthritis (OA) are characterized by joint and systemic high- or low-grade inflammation, respectively. Adipose tissue (AT) may contribute to the pathogenesis of these diseases. To address this issue, we investigated whether basal and pro-inflammatory cytokine (IL-1beta)-triggered release of adipocytokines (TNF, IL-6, IL-10, IL-1Ra, TGFbeta, CCL2/MCP-1, CCL5/RANTES, MMP-3) from subcutaneous (ScAT) and intraarticular (AAT) adipose tissues of RA and OA patients mirror differences between these diseases in an intensity of systemic and local inflammation. We found that in both diseases basal adipocytokine release was usually higher from AAT than ScAT, reflecting stronger local than systemic inflammation. However, ScAT secreted considerable amounts of pro- and anti-inflammatory factors as well. Spontaneous secretion of some adipocytokines (MMP-3 and/or TNF, CCL2/MCP-1, IL-1Ra) was higher in osteoarthritis than rheumatoid ATs and probably caused by weaker anti inflammatory treatment of OA patients. By contrast, reactivity of ATs to IL-1beta was significantly lower in OA than RA and IL-1beta antagonist (IL-1Ra) could be responsible for this because we found its overproduction in OA ATs. Interestingly, higher reactivity of ScAT than AAT to IL-1beta was a characteristic for OA while reactivity of rheumatoid ScAT and AAT to this stimulus was equal. We conclude that differences between OA and RA in reactivity of AAT and ScAT to pro-inflammatory stimulus mimicking in vivo condition reflect dissimilarity in an intensity of disease-specific inflammation and thus support contribution of ATs to these pathological processes. Moreover, we propose that more efficient anti-inflammatory mechanism(s) are preserved in ATs of OA than RA patients. PMID- 30280296 TI - LGBT+ Individuals' Perceptions of Healthcare Services in Turkey: A Cross sectional Qualitative Study. AB - When accessing healthcare services, LGBT+ individuals are often exposed to segregating and marginalizing discourses. Knowledge about how such experiences are reflected in the moral world of LGBT+ individuals living in Turkey is limited. This study examined LGBT+ individuals' lived experiences when utilizing healthcare services. The findings are discussed in terms of moral discourses related to LGBT+ individuals' gender identity and sexual orientation. A qualitative field study was conducted using semi-structured interviews with fifty five LGBT+ individuals from Turkish cities who were in contact with various non governmental organizations that conduct studies on gender identity and sexual orientation. A questionnaire was administered with items on participants' demographic information, experiences, behavioural patterns, and knowledge regarding healthcare services. The data were analysed thematically. The findings were evaluated within the framework of "access to healthcare service" theme related to "healthcare service demand" context. Additionally, the "interaction with physicians" theme was addressed in the context of "physician patient/counselee relationship." LGBT+ individuals state that they are exposed to stigmatizing and segregating discourses by healthcare professionals, which might pose an obstacle for adaptive health-seeking behaviours. These results suggest that physicians' professional approach has a considerable influence on LGBT+ individuals' capacity for utilizing healthcare services. PMID- 30280294 TI - Reverse Engineering the 1-Month Lupron Depot(r). AB - The 1-month Lupron Depot(r) (LD) encapsulating water-soluble leuprolide in poly(lactic-co-glycolic acid) (PLGA) microspheres is a benchmark product upon which modern long-acting release products are often compared. Despite expiration of patent coverage, no generic product for the LD has been approved in the USA, likely due to the complexity of components and manufacturing processes involved in the product. Here, we describe the reverse engineering of the LD composition and important product attributes. Specific attributes analyzed for microspheres were as follows: leuprolide content by three methods; gelatin content, type, and molecular weight distribution; PLGA content, lactic acid/glycolic acid ratio, and molecular weight distribution; mannitol content; in vitro drug release; residual solvent and moisture content; particle size distribution and morphology; and glass transition temperature. For the diluent, composition, viscosity, and specific gravity were analyzed. Analyzed contents of the formulation and the determined PLGA characteristics matched well with the official numbers stated in the package insert and those found in literature, respectively. The gelatin was identified as type B consistent with ~ 300 bloom. The 11-MUm volume-median microspheres in the LD slowly released the drug in vitro in a zero-order manner after ~ 23% initial burst release. Very low content of residual moisture (< 0.5%) and methylene chloride (< 1 ppm) in the product indicates in-water drying is capable of removing solvents to extremely low levels during manufacturing. The rigorous approach of reverse engineering described here may be useful for development of generic leuprolide-PLGA microspheres as well as other new and generic PLGA microsphere formulations.

PMID- 30280298 TI - Investigation by Fluorescence Technique of the Quenching Effect of Co2+ and Mn2+ Transition Metals, on Naphthalene-Methyl-Beta-Cyclodextrin Host-Guest Inclusion Complex. AB - Inclusion complex of naphthalene with methyl-beta-cyclodextrin in water has been formed. The aqueous solutions of the various amounts of Co2+ve Mn2+salts have been added to naphthalene-methyl-beta-cyclodextrin (NAP-Me-beta-CD) inclusion complexes. Fluorescence properties of the naphthalene (NAP) compound have been utilized to observe the changes in fluorescence intensities. Stern-Volmer quenching constants and fluorescence quantum yields have been calculated. Characterization of the resulting complex by FT-IR and 1H NMR technique has been determined. Fluorescence lifetime measurements have been made in the presence and absence of the quenching reagent and Gibbs free energy change has been calculated. PMID- 30280299 TI - Prediction of femtosecond laser ablation profile on human teeth. AB - To predict the laser ablation profile on dental hard tissue which will enable the user to optimize laser parameters so as to carry out the laser treatment with minimal tissue damage. The present study constructs a mathematical model to predict the ablation profile based on Gaussian beam distribution of laser intensity and correlates the model with experimentally obtained ablation parameters (effective Gaussian beam radius, ablation threshold fluence, and effective energy penetration depth). To obtain the ablation parameters, laser ablation experiments were carried out on dental hard tissues using Ti:Sapphire femtosecond laser (800 nm, 100 fs, 10 kHz). The method is further extended to predict the ablation rate and efficiency as well. The profile predicted from the mathematical model is compared with that of experimental results. It is found that the predicted ablation profile agrees well with the experimental profile for both enamel and dentin except a slight deviation at higher fluence for dentin. The calculated ablation rate is comparable to that of experimental results whereas for ablation efficiency appreciable deviation is observed in the case of dentin. The model succinctly predicts the ablation profile, ablation rate, and ablation efficiency which will enable to perform dental surgery at optimized laser processing conditions with high precision thus reducing the tissue damage appreciably. Once the details of lesion are known through proper diagnostic tools, the method enables the user to readily obtain optimum laser parameters. It can be used as a handy reference for dentists to perform damage-free surgery, ensuring quicker healing. PMID- 30280300 TI - Quantitative evaluation of skin shrinkage associated with non-invasive skin tightening: a simple method for reproducible linear measurement using microtattoos. AB - Non-invasive skin-tightening devices can induce thermal denaturation and skin shrinkage via externally applied radiofrequency emissions or high-frequency ultrasound. Therefore, the purpose of this study is to develop and test a method for measurement of skin reduction associated with application of such energy devices. Twenty-five healthy participants with mild to moderate skin laxity of the arms were enrolled. Pinpoint microtattoos were placed at each of the treatment sites to delineate two 6 * 12 cm rectangles per subject. A non stretchable filament, tape and marking pen apparatus was used to measure the size of each rectangle before treatment and at follow-up visit by two blinded investigators. After randomization, one side received a single pass with a radiofrequency device (6.78 MHz), while the contralateral side received multiple passes. Participants underwent two treatment sessions to each side 2 weeks apart, and returned for follow-up 4 weeks after the second treatment. Length and area measurement were analyzed to assess precision and accuracy of measurements and to compare efficacy of treatment between pre- and post-treatment. Concordance correlation coefficients (CCC) demonstrated substantial inter-investigator reliability and precision in length measurements (CCC, 0.94 to 0.98 in pre treatment; 0.95 to 0.98 in post-treatment). Measurements at the 6-week post treatment follow-up demonstrated a statistically significant skin reduction in all six of the measured parameters. A simple skin measurement method requiring minimal instrumentation can quantitatively evaluate skin shrinkage associated with non-invasive skin-tightening devices. PMID- 30280301 TI - Stochastic Modelling of Air Pollution Impacts on Respiratory Infection Risk. AB - The impact of air pollution on people's health and daily activities in China has recently aroused much attention. By using stochastic differential equations, variation in a 6 year long time series of air quality index (AQI) data, gathered from air quality monitoring sites in Xi'an from 15 November 2010 to 14 November 2016 was studied. Every year the extent of air pollution shifts from being serious to not so serious due to alterations in heat production systems. The distribution of such changes can be predicted by a Bayesian approach and the Gibbs sampler algorithm. The intervals between changes in a sequence indicate when the air pollution becomes increasingly serious. Also, the inflow rate of pollutants during the main pollution periods each year has an increasing trend. This study used a stochastic SEIS model associated with the AQI to explore the impact of air pollution on respiratory infections. Good fits to both the AQI data and the numbers of influenza-like illness cases were obtained by stochastic numerical simulation of the model. Based on the model's dynamics, the AQI time series and the daily number of respiratory infection cases under various government intervention measures and human protection strategies were forecasted. The AQI data in the last 15 months verified that government interventions on vehicles are effective in controlling air pollution, thus providing numerical support for policy formulation to address the haze crisis. PMID- 30280302 TI - Occupational and patient radiation doses in a modern cardiac electrophysiology laboratory. AB - PURPOSE: Technological advancements have greatly expanded the field of cardiac electrophysiology, requiring greater demands on imaging systems and potentially delivering higher radiation doses to patients and operators. With little contemporary research on occupational and patient radiation risk in the electrophysiology laboratory, the aim of this study was to analyze radiation doses, including occupational fetal doses, over approximately the last decade. We benchmarked the occupational data to our patient radiation dose data to allow for comparison and to put into perspective the associated radiation risks. METHODS: Occupational radiation dosimetry analyzed included data from an 11-year period for physicians, a 7-year period for nurses, and a 9-year period for fetal doses. Patient-related dose metrics over an 8-year period were also analyzed. RESULTS: In the physician and nursing groups, there was a nearly 70% decrease in the average occupational radiation doses over the given periods. Within the electrophysiology department, the average fetal occupational doses were very low, close to 0 MUSv. The average reference point air kerma per patient for all electrophysiology procedures decreased from nearly 600 mGy/procedure in 2010 to just over 100 mGy/procedure in 2017. CONCLUSIONS: Patient and occupational radiation doses in our laboratories significantly decreased over the periods analyzed as a result of clinical and technical staff efforts as well as advances in imaging technology. The radiation-related risk to individuals working in our electrophysiology laboratories, including pregnant women, is very low. Data reported herein could be used by other institutions to evaluate their occupational and patient radiation safety practices. PMID- 30280303 TI - Idiopathic ventricular arrhythmias arising from the posterior septum of tricuspid and mitral annuli: comparison of electrocardiographic characteristics and outcomes of catheter ablation. AB - PURPOSE: Ventricular arrhythmia (VA) arising from the tricuspid annulus in the posterior septum (PS) (TAPS-VA) has similar electrocardiographic characteristics as VA arising from the mitral annulus in the PS (MAPS-VA) because the two locations are adjacent. We examined the electrocardiographic characteristics that differentiate MAPS-VA from TAPS-VA and the efficacy of catheter ablation. METHODS: We studied 13 patients whose VAs were successfully ablated in the TAPS (n = 7) and MAPS (n = 6). RESULTS: QRS morphologies of both groups were characterized by left and right bundle block morphologies in lead V1, superior axis deviation, and precordial transition at <= lead V3 in nine patients. Compared with TAPS-VA, MAPS-VA had (1) R < S wave in lead II, (2) precordial transition in lead V2, (3) s-wave in lead V6, and (4) slurred initial part of the QRS complex in the precordial leads, e.g., [4a] pseudo delta wave >= 34 ms, [4b] intrinsicoid deflection time >= 85 ms, and [4c] maximum deflection index >= 0.55. Patients who met >= 2 of (1)-(3) and any of [4a]-[4c] could be classified as having MAPS-VA, with a sensitivity and specificity of 100%. VA recurred in one patient in the TAPS group during the median follow-up of 7 (interquartile range 6 to 15.5) months. CONCLUSIONS: VA arising from the PS has superior axis deviation, and left and right bundle block morphologies with relatively early precordial transition. MAPS-VA can be differentiated from TAPS-VA based on electrocardiographic characteristics. This study provides useful information for treatment involving catheter ablation for VA arising from the PS. PMID- 30280304 TI - Machine learning approach to identify a resting-state functional connectivity pattern serving as an endophenotype of autism spectrum disorder. AB - Endophenotype refers to a measurable and heritable component between genetics and diagnosis, and the same endophenotype is present in both individuals with a diagnosis and their unaffected siblings. Determination of the neural correlates of an endophenotype and diagnosis is important in autism spectrum disorder (ASD). However, prior studies enrolling individuals with ASD and their unaffected siblings have generally included only one group of typically developing (TD) subjects; they have not accounted for differences between TD siblings. Thus, they could not differentiate the neural correlates for endophenotype from the clinical diagnosis. In this context, we enrolled pairs of siblings with an ASD endophenotype (individuals with ASD and their unaffected siblings) and pairs of siblings without this endophenotype (pairs of TD siblings). Using resting-state functional MRI, we first aimed to identify an endophenotype pattern consisting of multiple functional connections (FCs) then examined the neural correlates of FCs for ASD diagnosis, controlling for differences between TD siblings. Sparse logistic regression successfully classified subjects as to the endophenotype (area under the curve = 0.78, classification accuracy = 75%). Then, a bootstrapping approach controlling for differences between TD siblings revealed that an FC between the right middle temporal gyrus and right anterior cingulate cortex was substantially different between individuals with ASD and their unaffected siblings, suggesting that this FC may be a neural correlate for the diagnosis, while the other FCs represent the endophenotype. The current findings suggest that an ASD endophenotype pattern exists in FCs, and a neural correlate for ASD diagnosis is dissociable from this endophenotype. (250 words). PMID- 30280305 TI - Treatment of Hereditary Angioedema Attacks with Icatibant and Recombinant C1 Inhibitor During Pregnancy. AB - PURPOSE: Hereditary angioedema (HAE) is a rare disease caused by a C1 inhibitor (C1-INH) deficit. Clinically, HAE is manifested by repeated episodes of localized subcutaneous or submucosal oedema attacks. Managing HAE patients in pregnancy is challenging, since there are only limited data on the safety and efficacy of various therapeutic approaches. METHODS: We present our clinical experience treating acute HAE attacks during pregnancy in six consecutive patients. RESULTS: During the pregnancies, 79 HAE attacks occurred. The most frequent were abdominal 53 (67.1%) followed by peripheral 21 (26.6%), facial 10 (12.7%), and laryngeal 10 (12.7%) oedemas; 13 (16.5%) attacks were combined. Fifty (63.3%) attacks were treated with recombinant human C1-INH (rhC1-INH); 17 (21.5%) with plasma-derived, pasteurized, nanofiltered C1-INH (pnfC1-INH); 13 (16.5%) with icatibant; and 1 (1.3%) with plasma-derived, nanofiltered C1-INH (nfC1-INH). Treatment had to be repeated in 5 attacks (6.3%). All six deliveries (one caesarean section and five spontaneous vaginal deliveries) were complication free. All pregnancies went to the full term and the patients delivered healthy babies with a birth weight ranging from 2850 to 3690 g. No congenital abnormalities were detected in the neonates. No abortions occurred. CONCLUSIONS: Our results show good C1-INH or icatibant treatment efficacy for HAE attacks in pregnancy. The treatment by the first drug used was effective in 93.7% of all attacks. In 6.3% of attacks, a second treatment had to be used. No adverse effects were observed.

AB - Malignant cell transformation could be considered as a series of cell reprogramming events driven by oncogenic transcription factors and upstream signalling pathways. Chromatin plasticity and dynamics are critical determinants in the control of cell reprograming. An increase in chromatin dynamics could therefore constitute an essential step in driving oncogenesis and in generating tumour cell heterogeneity, which is indispensable for the selection of aggressive properties, including the ability of cells to disseminate and acquire resistance to treatments. Histone supply and dosage, as well as histone variants, are the best-known regulators of chromatin dynamics. By facilitating cell reprogramming, histone under-dosage and histone variants should also be crucial in cell transformation and tumour metastasis. Here we summarize and discuss our knowledge of the role of histone supply and histone variants in chromatin dynamics and their ability to enhance oncogenic cell reprogramming and tumour heterogeneity. PMID- 30280308 TI - Epidemic obesity in children and adolescents: risk factors and prevention. AB - The prevalence of obesity among children and adolescents (aged 2-18 years) has increased rapidly, with more than 100 million affected in 2015. Moreover, the epidemic of obesity in this population has been an important public health problem in developed and developing countries for the following reasons. Childhood and adolescent obesity tracks adulthood obesity and has been implicated in many chronic diseases, including type 2 diabetes, hypertension, and cardiovascular disease. Furthermore, childhood and adolescent obesity is linked to adulthood mortality and premature death. Although an imbalance between caloric intake and physical activity is a principal cause of childhood and adolescent obesity, environmental factors are exclusively important for development of obesity among children and adolescents. In addition to genetic and biological factors, socioenvironmental factors, including family, school, community, and national policies, can play a crucial role. The complexity of risk factors for developing obesity among children and adolescents leads to difficulty in treatment for this population. Many interventional trials for childhood and adolescent obesity have been proven ineffective. Therefore, early identification and prevention is the key to control the global epidemic of obesity. Given that the proportion of overweight children and adolescents is far greater than that of obesity, an effective prevention strategy is to focus on overweight youth, who are at high risk for developing obesity. Multifaceted, comprehensive strategies involving behavioral, psychological, and environmental risk factors must also be developed to prevent obesity among children and adolescents. PMID- 30280309 TI - Iodine Nutrition and Thyroid Function in Pregnant Women Exposed to Different Iodine Sources. AB - Pregnant women are more vulnerable to iodine deficiency and iodine excess. The study aimed to assess the changes in iodine nutrition and thyroid function of pregnant women exposed to different iodine sources resulting in various iodine intakes during pregnancy. From 2016 to 2017, 2004 healthy pregnant women aged 20 35 years from Shandong and Tianjin, China, were enrolled. Urinary iodine concentration (UIC), drinking water iodine content (WIC), thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), free thyroid hormone (FT4), thyroglobulin (Tg), serum thyroid peroxidase antibody (TPOAb), and thyroglobulin antibody (TgAb) were measured. Pregnant women in both Shandong and Tianjin were iodine sufficient, but the median UIC in pregnant women was significantly higher in Shandong (244 MUg/L) than that in Tianjin (159 MUg/L). No differences were found in UIC over the course of gestation in Shandong. In Tianjin, the UIC decreased during 13-24 weeks and stabilized thereafter. Compared with Tianjin, TSH levels were higher and FT3 and FT4 levels were lower in Shandong. Both FT3 and FT4 significantly decreased during pregnancy in Shandong and Tianjin. TSH and Tg increased over the course of gestation in both Shandong and Tianjin. The iodine status of pregnant women in Tianjin and Shandong were sufficient, but different changing patterns in UIC and thyroid function during pregnancy were presented. More attention should be focused on iodine nutrition of pregnant women, even in iodine-sufficient areas. PMID- 30280310 TI - Impact of fixation, coil, and number of excitations on diffusion tensor imaging of rat brains at 7.0 T. AB - BACKGROUND: We sought to compare diffusion tensor imaging (DTI) parameters in vivo and ex vivo in the brain and to explore the effects of radiofrequency coil and number of excitations on ex vivo DTI parameters. METHODS: Six Sprague-Dawley rat brains were used to obtain in vivo and ex vivo DTI maps with different coils and number of excitations. DTI parameters of white matter and grey matter including diffusivities, fractional anisotropy, and other dimensionless ratios (lambda2/lambda1, lambda3/lambda1, and lambda2/lambda3) were obtained from reconstruction maps. Comparisons of ex vivo signal-to-noise ratio with different coils and number of excitations were conducted. RESULTS: Diffusivities decreased significantly after fixation in all the selected white matter and grey matter regions of interest (all at p < 0.001). The diffusivities in white matter integrity decreased more than in grey matter integrity after fixation (all at p < 0.001). The ratio of lambda2/lambda3 in the major brain structures changed after fixation (most at p < 0.05). There were differences in major ex vivo brain structures in DTI parameters and signal-to-noise ratio between surface coil and volume coil, and between one and four excitations (most at p < 0.05). CONCLUSION: The impact of fixation, coil, and number of excitations on DTI parameters should be taken into consideration in clinical and experimental studies at 7.0 T. PMID- 30280311 TI - In vitro comparison of microleakge between preformed metal crowns and aesthetic crowns of primary molars using different adhesive luting cements. AB - AIM: To assess and compare the microleakage extent between preformed metal crowns (PMCs), preveneered PMCs and zirconia crowns using different adhesive luting cements. METHODS: Thirty-six primary first molars were divided into three groups (n = 12) each prepared to receive different crowns (PMCs, preveneered PMCs, or zirconia crowns). Each group was further sub-grouped (n = 4) according to the luting cement (resin cement, resin modified glass ionomer cement, or glass ionomer cement). After cementation, the teeth were thermocycled, placed in 0.5% basic fuchsin, and sectioned to assess dye penetration. The results were analysed using ANOVA and Bonferroni statistical tests. The level of significance was set at p < 0.05. RESULTS: The microleakage recorded in zirconia crowns was significantly worse than that in preveneered PMCs and PMCs (p < 0.001). Regardless of the crown type, resin cement resulted in the least microleakage with statistically significant differences from glass ionomer cement (p < 0.05). CONCLUSIONS: As far as microleakage is concerned, preveneered PMCs seem to be an aesthetic and suitable alternative to PMCs. In addition, resin cement stands to be the most optimum luting cement. PMID- 30280312 TI - Sodium acetate improves disrupted glucoregulation and hepatic triglyceride content in insulin-resistant female rats: involvement of adenosine deaminase and dipeptidyl peptidase-4 activities. AB - Combined oral contraceptive (COC) treatment has been shown to be associated with glucose deregulation and increased triglyceride levels, but the mechanisms are elusive. Soluble dipeptidyl peptidase-4 (sDPP-4) and adenosine deaminase (ADA) are involved in the initiation and/or progression of cardiometabolic disorders. We therefore, hypothesized that increased DPP-4 and ADA activities are involved in glucose deregulation and hepatic triglyceride accumulation induced by COC treatment. This study also investigated whether short-chain fatty acid, acetate, would protect against COC-induced dysmetabolic effects. Female Wistar rats received (p.o.) vehicle and COC (1.0 MUg ethinylestradiol plus 5.0 MUg levonorgestrel) with or without sodium acetate (ACE; 200 mg) for 8 weeks. Treatment with COC led to increased plasma triglyceride-glucose index, 1-h postload glucose response, insulin, free fatty acid, insulin resistance, and impaired glucose tolerance. COC treatment also resulted in increased plasma and hepatic triglycerides (TG), TG/HDL-cholesterol ratio, malondialdehyde, uric acid, lactate dehydrogenase, DPP-4, ADA, and xanthine oxidase (XO) activities. On the other hand, COC led to reduction in nitric oxide level. However, ACE significantly ameliorated the alterations induced by COC treatment, but XO activity remains elevated during COC treatment. This result also demonstrates that increased DPP-4 and ADA activities are at least in part involved in glucose deregulation and hepatic TG accumulation induced by COC treatment. Therefore, sodium acetate would impact positively on cardiometabolic disorders, at least in part, by inhibition of DPP-4 and ADA activities.

We report on the efficacy of HDX-MS to distinguish between native and non-native proteins using a popular approach to calculate HDX protection factors (PFs) from protein structures. The ability of HDX-MS to identify native protein conformations is quantified by binary structural classification such that merits of the approach for protein modelling can be quantified and better understood. We show that highly accurate PF calculations are not a prerequisite for HDX-MS simulations that are capable of effectively discriminating between native and non native protein folds. The simulations can also be performed directly on unique structures facilitating high-throughput evaluation of many alternate conformations. The ability of HDX-MS to classify the conformations of homo protein assemblies is also investigated. In contrast to protein monomers, we show a significant lack of correspondence between the simulated and experimental HDX MS data for these systems with a subsequent decrease in the ability of HDX-MS to identify native states. However, we demonstrate surprisingly high diagnostic ability of the simulated data for assemblies in which a significant proportion of the individual chains occupy protein-protein interfaces. We relate this to the number of peptides that can sample alternate subunit orientations and discuss these observations within the larger context of applying HDX-MS to evaluate protein structures. Graphical Abstract. PMID- 30280314 TI - On-substrate Enzymatic Reaction to Determine Acetylcholinesterase Activity in Whole Blood by Paper Spray Mass Spectrometry. AB - Currently, all assays measuring acetylcholinesterase (AChE) activity following a suspected nerve agent exposure leverage methodologies that fail to identify the agent. This limits the overall effectiveness and ability to administer proper countermeasures. As such, there is an urgent need to identify novel, rapid, and more comprehensive approaches to establish AChE activity, including identification of the toxicant. Paper spray mass spectrometry was used to monitor the activity of acetylcholinesterase, both in-solution and on modified hydrophobic paper surface. Hydrophobic paper surfaces were prepared using vaporized trichloro(3,3,3-trifluoropropyl)silane. In both approaches, mixtures of diluted human whole blood with and without VX were mixed with a non-endogenous AChE specific substrate, 1,1-dimethyl-4-acetylthiomethylpiperidinium (MATP+). Formation of the cleaved MATP+ product was monitored over time and compared to MATP+ to determine relative AChE activity. This on-substrate assay was effective at determining AChE activity and identifying the toxicant; however, determination of AChE activity in-solution proceeded at a slower rate. The on-substrate assay serves as a pioneering example of an enzymatic reaction occurring on the surface of a paper spray ionization ticket. This work broadens the range of applications relating to paper spray ionization-based clinical diagnostic assays. Graphical Abstract ?. PMID- 30280316 TI - Early life stress and trauma: developmental neuroendocrine aspects of prolonged stress system dysregulation. AB - Experience of early life stress (ELS) and trauma is highly prevalent in the general population and has a high public health impact, as it can trigger a health-related risk cascade and lead to impaired homeostatic balance and elevated cacostatic load even decades later. The prolonged neuropsychobiological impact of ELS can, thus, be conceptualized as a common developmental risk factor for disease associated with increased physical and mental morbidity in later life. ELS during critical periods of brain development with elevated neuroplasticity could exert a programming effect on particular neuronal networks related to the stress response and lead to enduring neuroendocrine alterations, i.e., hyper- or hypoactivation of the stress system, associated with adult hypothalamic-pituitary adrenal axis and glucocorticoid signaling dysregulation. This paper reviews the pathophysiology of the human stress response and provides evidence from human research on the most acknowledged stress axis-related neuroendocrine pathways exerting the enduring adverse effects of ELS and mediating the cumulative long term risk of disease vulnerability in adulthood. PMID- 30280313 TI - Chinese guidelines for the diagnosis and treatment of hand, foot and mouth disease (2018 edition). AB - BACKGROUND: Hand, foot, and mouth disease (HFMD) is a common infectious disease in childhood caused by an enterovirus (EV), and which is principally seen in children under 5 years of age. To promote diagnostic awareness and effective treatments, to further standardize and strengthen the clinical management and to reduce the mortality of HFMD, the guidelines for diagnosis and treatment have been developed. METHODS: National Health Commission of China assembled an expert committee for a revision of the guidelines. The committee included 33 members who are specialized in diagnosis and treatment of HFMD. RESULTS: Early recognition of severe cases is utmost important in diagnosis and treatment of patients with HFMD. The key to diagnosis and treatment of severe cases lies in the timely and accurate recognition of stages 2 and 3 of HFMD, in order to stop progression to stage 4. Clinicians should particularly pay attention to those EV-A71 cases in children aged less than 3 years, and those with disease duration less than 3 days. The following indicators should alert the clinician of possible deterioration and impending critical disease: (1) persistent hyperthermia; (2) involvement of nervous system; (3) worsening respiratory rate and rhythm; (4) circulatory dysfunction; (5) elevated peripheral WBC count; (6) elevated blood glucose and (7) elevated blood lactic acid. For treatment, most mild cases can be treated as outpatients. Patients should be isolated to avoid cross-infection. Intense treatment modalities should be given for those severe cases. CONCLUSION: The guidelines can provide systematic guidance on the diagnosis and management of HFMD. PMID- 30280317 TI - Environmental Selenium and Human Health: an Update. AB - PURPOSE OF REVIEW: Selenium, a trace element, is ubiquitous in the environment. The main source of human exposure is diet. Despite its nutritional benefits, it is one of the most toxic naturally occurring elements. Selenium deficiency and overexposure have been associated with adverse health effects. Its level of toxicity may depend on its chemical form, as inorganic and organic species have distinct biological properties. RECENT FINDINGS: Nonexperimental and experimental studies have generated insufficient evidence for a role of selenium deficiency in human disease, with the exception of Keshan disease, a cardiomyopathy. Conversely, recent randomized trials have indicated that selenium overexposure is positively associated with type 2 diabetes and high-grade prostate cancer. In addition, a natural experiment has suggested an association between overexposure to inorganic hexavalent selenium and two neurodegenerative diseases, amyotrophic lateral sclerosis and Parkinson's disease. Risk assessments should be revised to incorporate the results of studies demonstrating toxic effects of selenium. Additional observational studies and secondary analyses of completed randomized trials are needed to address the uncertainties regarding the health risks of selenium exposure. PMID- 30280318 TI - The folate receptor beta as a macrophage-mediated imaging and therapeutic target in rheumatoid arthritis. AB - Macrophages play a key role in the pathophysiology of rheumatoid arthritis (RA). Notably, positive correlations have been reported between synovial macrophage infiltration and disease activity as well as therapy outcome in RA patients. Hence, macrophages can serve as an important target for both imaging disease activity and drug delivery in RA. Folate receptor beta (FRbeta) is a glycosylphosphatidyl (GPI)-anchored plasma membrane protein being expressed on myeloid cells and activated macrophages. FRbeta harbors a nanomolar binding affinity for folic acid allowing this receptor to be exploited for RA disease imaging (e.g., folate-conjugated PET tracers) and therapeutic targeting (e.g., folate antagonists and folate-conjugated drugs). This review provides an overview of these emerging applications in RA by summarizing and discussing properties of FRbeta, expression of FRbeta in relation to macrophage polarization, FRbeta targeted in vivo imaging modalities, and FRbeta-directed drug targeting.

PMID- 30280320 TI - Changes in automated external defibrillator use and survival after out-of hospital cardiac arrest in the Nijmegen area. AB - PURPOSE: Out-of-hospital cardiac arrests (OHCAs) are a major healthcare problem. Over the years, several initiatives have contributed to more lay volunteers providing cardiopulmonary resuscitation (CPR) and increased use of automated external defibrillators (AEDs) in the Netherlands. As part of a quality and outcomes program, we registered bystander CPR, AED use and outcome in the Nijmegen area. METHODS: Prospective resuscitation registry with a study cohort of non-traumatic OHCA cases from 2013-2016 and historical controls from 2008-2011. In line with previous reports, we studied patients transported to the hospital (Radboudumc, Nijmegen, the Netherlands) and excluded arrests witnessed by the emergency medical service (EMS). Primary outcomes were return of spontaneous circulation (ROSC) and survival to discharge. RESULTS: In the study cohort (n = 349) the AED was attached more often than in the historical cohort (n = 180): 46% vs. 23% and the proportion of bystander CPR was higher: 78% vs. 63% (both p < 0.001). A higher proportion of patients received an AED shock (39% vs. 15%, p < 0.001) and the number of required shocks by the EMS was lower (2 vs. 4, p = 0.004). Survival to discharge was higher (47% vs. 33%, p = 0.002) without differences in ROSC. The survival benefit was restricted to patients with a shockable initial rhythm. In both cohorts, bystander CPR and AED use were independently associated with survival. CONCLUSION: In patients admitted after OHCA, survival to discharge has markedly improved to 40-50%, comparable with other Dutch registries. As increased bystander CPR and the doubled use of AEDs seem to have contributed, all civilian-based resuscitation initiatives should be encouraged. PMID- 30280321 TI - Leptoceridae (Insecta, Trichoptera) from Serra da Canastra Mountain Range, Southeast Brazil: Diversity, Distribution, and Description of Two New Species. AB - The Brazilian savanna, also known as Cerrado, is one of the world's biodiversity hotspots, covering about 22% of the country. Nevertheless, this region has been suffering an accelerated process of degradation due to the agribusiness expansion. This study contributes to increasing knowledge on the Leptoceridae fauna of the Serra da Canastra Mountains at the Minas Gerais State, Brazil. Herein, we illustrate and describe two new species of Leptoceridae, Notalina franciscana sp. nov. and Oecetis catagua sp. nov., and provide additional data on the richness and distribution of Leptoceridae species in the Parque Nacional da Serra da Canastra and surrounding areas. Furthermore, ten species are firstly recorded from Minas Gerais State, increasing the number of Leptoceridae species recorded in the state from 30 to 42. PMID- 30280323 TI - [Lung cancer under stress]. AB - BACKGROUND: Autophagy is a cellular mechanism involved in maintaining cellular homeostasis and warranting cellular survival under stress, and may be therapeutically exploited. Autophagy assessment in vitro is well established, but analysis in formalin-fixed and paraffin-embedded (FFPE) tissue is still poorly standardized. Expression analysis of autophagy-associated markers in diagnostic FFPE tissue aids in translating in vitro findings to the clinic and may contribute to a future quest for predictive markers. MATERIAL AND METHODS: We have established a reliable visualization of autophagy-related proteins in FFPE tissue by immunohistochemistry, using lung cancer cell lines with functionally modified autophagy states and marker-depletion, respectively, and evaluated the prognostic impact of autophagy-related markers in lung cancer patients. RESULTS: Dot-like staining was observed for LC3 and p62, representing the degrading autophagic vesicles. Stainings correlated significantly with quantitative protein expression assessed by western blot in cell lines and FFPE tumor tissue. In stage I/II non-small cell lung cancer cases and a large cohort of pulmonary squamous cell carcinomas, dot-like LC3 and p62 staining lacked clear prognostic value, but p62 expression was an independent prognostic factor for shorter survival in both cohorts and using internal validation models. CONCLUSIONS: Valid visualization of autophagy-related markers in FFPE tissue is feasible. We could not demonstrate a clear prognostic role of autophagy status as deducted from LC3-p62 co-expression. The autophagy independent role of p62 in lung cancer warrants further investigation, as well as crosstalk with other stress factors or the role of autophagy induction during or after treatment. PMID- 30280322 TI - Interactions of cantharidin-like inhibitors with human protein phosphatase-5 in a Mg2+ system: molecular dynamics and quantum calculations. AB - The serine/threonine protein phosphatase type 5 (PP5) is a promising target for designing new antitumor drugs. This enzyme is a member of the PPP phosphatases gene family, which catalyzes a dephosphorylation reaction: a regulatory process in the signal transduction pathway that controls various biological processes. The aim of this work is to study and compare the inhibition of PP5 by ten cantharidin-like inhibitors in order to bring about contributions relevant to the better comprehension of their inhibitory activity. In this theoretical investigation, we used molecular dynamics techniques to understand the role of key interactions that occur in the protein active site; QM calculations were employed to study the interaction mode of these inhibitors in the enzyme. In addition, atoms in molecules (AIM) calculations were carried out to characterize the chemical bonds among the atoms involved and investigate the orbital interactions with their respective energy values. The obtained results suggest that the Arg275, Asn303, His304, His352, Arg400, His427, Glu428, Val429, Tyr451, and Phe446 residues favorably contribute to the interactions between inhibitors and PP5. However, the Asp271 and Asp244 amino acid residues do not favor such interactions for some inhibitors. Through the QM calculations, we can suggest that the reactional energy of the coordination mechanism of these inhibitors in the PP5 active site is quite important and is responsible for the inhibitory activity. The AIM technique employed in this work was essential to get a better comprehension of the transition states acquired from the mechanism simulation. This work offers insights of how cantharidin-like inhibitors interact with human PP5, potentially allowing the design of more specific and even less cytotoxic drugs for cancer treatments.

PMID- 30280325 TI - Microflora of normal maxillary sinuses: does it justify perioperative antibiotic treatment in sinus augmentation procedures. AB - OBJECTIVES: To investigate bacterial flora of normal maxillary sinuses in order to facilitate perioperative antibiotic management in sinus augmentation procedures. MATERIALS AND METHODS: Specimens of maxillary sinus mucosa were harvested during planned orthognatic surgery in 18 patients with no evidence of rhinosinusitis. The samples were processed according to hospital routine for aerobic and anaerobic cultures. RESULTS: Ten maxillary sinuses were found sterile. Twenty-six (72%) maxillary mucosa specimens were culture-positive. Aerobes were recovered in 21 sinus samples (58%), predominantly as polymicrobial flora (18 cultures, 50% of all specimens), S. aureus in 2 sinuses of the same patient (6% of the samples), and Bacillus sp. in 1 sinus (3%). Anaerobes were isolated in 20 of 26 culture-positive specimens (56% of all sinus samples). They were recovered alone in 5 samples. Fifteen anaerobic cultures were polymicrobial (42% of all samples). Propionibacterium acnes was isolated from another 5 sinuses (14%) of 3 patients. CONCLUSIONS: Our data support the policy of perioperative antibiotic prophylaxis in sinus augmentation procedures where Schneiderian membrane is perforated. CLINICAL RELEVANCE: Evaluating the need of a perioperative antibiotic therapy in sinus augmentation procedures. PMID- 30280324 TI - Evaluation of the genotoxic potential of different delivery methods of at-home bleaching gels: a single-blind, randomized clinical trial. AB - OBJECTIVE: This single-blind, parallel, randomized clinical trial evaluated the genotoxic potential and effectiveness of 10% hydrogen peroxide (HP) in patients submitted to at-home bleaching. MATERIALS AND METHODS: Sixty young volunteers with maxillary incisors equal to or darker than M1.5 were included in the study. Patients were submitted to bleaching for 14 days (30 min/day) with one of the three 10% HP treatments: the bleaching agent was delivered in a bleaching tray (White Class, FGM), whitening strips (White Strips, Oral-b), or in prefilled disposable trays (Opalescence Go, Ultradent). The color change was evaluated with the Vita Bleachedguide, and the micronucleus test of exfoliative oral mucosa was carried out, starting from a count of 1000 cells, at the baseline, immediately after and 30 days after the end of the treatment. The micronucleus data were evaluated with the Kruskal-Wallis and Wilcoxon tests and color change with the two-way ANOVA test and the Tukey test (alpha = 0.05). RESULTS: Significant whitening was observed for all groups after 14 days (p = 0.001) and was maintained after 30 days, with no difference between groups (p = 0.42). The micronucleus count did not indicate genotoxic potential in any of the groups studied (p = 0.32), irrespective of the time intervals (p = 0.62). CONCLUSION: No genotoxic effects of 10% HP were observed in patients submitted to at-home bleaching systems (30 min/day for 14 days), even 30 days after the end of treatment. CLINICAL SIGNIFICANCE: It is safe to use different systems to deliver 10% HP during at-home bleaching according to the manufacturers' recommendations, with no risk of genotoxic effects applied. PMID- 30280326 TI - Influence of different thickeners in at-home tooth bleaching: a randomized clinical trial study. AB - OBJECTIVES: To evaluate the effects of 10% carbamide peroxide (CP) with two different thickeners, carbopol (CPc) and natrosol (CPn), on color variation (CV), tooth sensitivity (TS), and cytotoxicity (CC). METHODS: Seventy subjects were distributed into the CPc or CPn groups (n = 35), in a parallel group, randomized, controlled, single-blind clinical trial. Bleaching gels were used by volunteers for 4 h daily for 2 weeks. Color evaluation was performed using a reflectance spectrophotometer, before bleaching treatment (BT), immediately after the first and second weeks of BT, and 1 week and 1 month after BT ended. TS was evaluated using two pain scales, before, during, and after BT. CC was evaluated using MTT after exposure of MDPC-23 cells to the bleaching gels for 4 h. Epoxy replicas of the subjects teeth were made before and after BT and analyzed using a scanning electronic microscope. The data was analyzed using statistical methods. RESULTS: CV and TS showed similar variation between both bleaching gels (p <= 0.05). None of the protocols affected cellular metabolism or the surface morphology of enamel. CONCLUSIONS: Bleaching gels with carbopol and natrosol as thickening agents produced similarly effective tooth bleaching and TS, but did not cause cytotoxicity. CLINICAL RELEVANCE: Natrosol could be an alternative as a thickener used in bleaching gels due to its similar bleaching effect and TS when compared with Carbopol. PMID- 30280328 TI - Combined effects of new complete denture fabrication and simplified dietary advice on nutrient intake in edentulous elderly patients for 6 months. AB - OBJECTIVE: The aim was to evaluate the combined effects of a new complete denture fabrication and simple dietary advice (using unique pamphlets) by dentists on nutrient intake in edentulous elderly patients. MATERIALS AND METHODS: A randomized controlled trial was performed on edentulous elderly patients who were randomly allocated to either an intervention or a control group. The intervention group received a new complete denture and simple dietary advice, whereas the control group received a new complete denture and denture care advice. The outcomes of this trial (nutrient intakes) were calculated using a brief-type self administered diet history questionnaire (BDHQ) and assessed at three time points (pretreatment and 3 and 6 months post-treatment). RESULTS: At 3 months post treatment, the intake of several nutrients such as proteins (p = 0.004), magnesium (p < 0.001), and vitamin B1 (p = 0.014) was significantly higher in the intervention group than the control group, whereas at 6 months post-treatment, plant protein (p = 0.028) intake was significantly higher in the intervention group than the control group. On the contrary, animal protein (p = 0.049) and vitamin B12 (p = 0.028) intakes were significantly higher in the control group. CONCLUSIONS: New complete denture fabrication with simple dietary advice might improve nutrient intake in elderly edentulous patients; however, the effect is probably short term. CLINICAL SIGNIFICANCE: New complete denture fabrication along with simple dietary advice by dentists might improve nutrient intake in edentulous elderly patients. Therefore, regular use of these interventions in the dental setting might have long-term effects on nutrient intake in elderly edentulous patients. TRIAL REGISTRATION: UMIN-CTR Clinical Trial, unique trial number: UMIN000017879. PMID- 30280327 TI - The effect of age, gender, and time between blood draw and start of centrifugation on the size outcomes of platelet-rich fibrin (PRF) membranes. AB - OBJECTIVES: Platelet-rich fibrin (PRF) has been utilized in regenerative dentistry as a supra-physiological concentrate of autologous growth factors capable of stimulating tissue regeneration. Due to the variability in the macroscopic morphology/size of PRF membranes observed between patients, we were interested in studying the effects of patient age, gender, and time between blood draw and the start of centrifugation on the size outcomes of PRF membranes. Despite PRF therapy being increasingly more popular in private practice, to date, no study has investigated the effects of the delay between blood draw and the start of centrifugation in a clinical setting. MATERIALS AND METHODS: A total of 60 patients enrolled in this study were divided into 6 groups of 10 patients each, including male and female patients categorized into age groups 21-40, 41 60, and 61-80 years. From each patient, a total of five PRF membranes were fabricated from 10-mL tubes following centrifugation starting after 0, 30, 60, 90, and 120 s. In total, 300 PRF membranes were produced in this study to investigate the effects of patient age, gender, and time on the size outcomes of PRF membranes. RESULTS: A longer delay by the clinician before starting centrifugation following blood draw led to a smaller final size of PRF membranes. At 90 s following blood draw, a significant (13%) reduction in PRF membrane size was observed. After 120 s, a significant (23%) reduction was observed. Additionally, female patients had on average 17% larger membranes compared to men (p < 0.05, 300 samples). Lastly, the size outcomes of the PRF membranes was largest in patients aged 61-80, followed by those aged 41-60 and 21-40. However, no statistically significant differences in PRF membrane sizes were reported between age groups. CONCLUSIONS: The time at which a centrifugation procedure begins following blood draw is critical to optimize the size outcomes of PRF membranes. In general, approximately 15 s is required per tube to harvest 9-10 cc of blood. Therefore, a 60- to 90-s interval between blood draw and the start of centrifugation should be a parameter that is respected by clinicians to avoid significant changes in the macroscopic morphology/size of fabricated PRF membranes. Furthermore, females and older patients produced larger membranes, likely due to lower red blood cell counts derived from their peripheral blood. CLINICAL RELEVANCE: The findings from the present study demonstrate that on average, a clinician has approximately 60-90 s between blood draw and the start of the centrifugation cycle to produce standard-sized PRF membranes. Shortly thereafter, a significant reduction in size is observed. Additionally, females and older patients were found to produce larger PRF membranes. Centrifugation protocols may therefore be adapted accordingly. PMID- 30280330 TI - Multiregional viscoelastic characterization of the corona radiata in the sagittal plane of the porcine brain. AB - Detailed finite element (FE) models are used as promising tools to investigate traumatic brain injuries, although their accuracy is strongly dependent on the characterization of the mechanical behaviors of the different anatomic structures in the brain. In some cases, when the FE models require finer spatial resolution, the heterogeneous and anisotropic corona radiata cannot be taken as a homogeneous whole body. In this work, indentation experiments were conducted on the anterior, superior, and posterior regions of the corona radiata in the sagittal plane. To determine the parameters available for computational modeling purposes, a linear viscoelastic model using the Boltzmann hereditary integral was fitted to the force-time data of the three regions. In the indentation tests, the superior region appeared to be the stiffest, while no significant differences were observed between the anterior and posterior regions until the viscoelastic tissue reached equilibrium. During the period of relaxation, statistical comparisons among the different regions indicated significant differences between the superior and anterior regions, and between the superior and posterior regions. This work complements existing investigations into the anatomic heterogeneity of the brain, and contributes toward improving the spatial resolution of future computational models. Graphical abstract Relaxation functions of different regions based on the Prony series parameters and the multiregional Kolmogorov Smirnov comparisons (*p < 0.017). The anisotropy and interregional differences of the corona radiata observed in this study are supplementary to the previous explorations of the mechanical properties of different brain anatomic structures. PMID- 30280329 TI - Mitigation of Oxidation in Therapeutic Antibody Formulations: a Biochemical Efficacy and Safety Evaluation of N-Acetyl-Tryptophan and L-Methionine. AB - PURPOSE: Biotherapeutics can be susceptible to oxidation during manufacturing and storage. Free L-methionine is known to protect methionine residues in proteins from oxidation. Similarly, free tryptophan and other indole derivatives have been shown to protect tryptophan residues from oxidation. N-acetyl-DL-tryptophan was previously identified as a potentially superior antioxidant to tryptophan as it has a lower oxidation potential and produces less peroxide upon light exposure. This study sought to confirm the antioxidant efficacy and safety of N-acetyl-DL tryptophan and L-methionine as formulation components for biotherapeutic drugs. METHODS: Antibodies were subjected to AAPH and light exposure in the presence of N-acetyl-DL-tryptophan and L-methionine. Oxidation in relevant CDR and Fc residues was quantified by peptide map. In silico, in vitro, and in vivo studies were performed to evaluate the safety of N-acetyl-DL-tryptophan and L-methionine. RESULTS: Peptide mapping demonstrated that N-acetyl-DL-tryptophan was effective at protecting tryptophans from AAPH stress, and that the combination of N-acetyl DL-tryptophan and L-methionine protected both tryptophan and methionine from AAPH stress. The safety assessment suggested an acceptable safety profile for both excipients. CONCLUSIONS: N-acetyl-tryptophan and L-methionine effectively reduce the oxidation of susceptible tryptophan and methionine residues in antibodies and are safe for use in parenteral biotherapeutic formulations. PMID- 30280331 TI - Head-mounted interface for intuitive vision control and continuous surgical operation in a surgical robot system. AB - Although robot-assisted surgeries offer various advantages, the discontinuous surgical operation flow resulting from switching the control between the patient side manipulators and the endoscopic robot arm can be improved to enhance the efficiency further. Therefore, in this study, a head-mounted master interface (HMI) that can be implemented to an existing surgical robot system and allows continuous surgical operation flow using the head motion is proposed. The proposed system includes an HMI, a four degrees of freedom endoscope control system, a simple three-dimensional endoscope, and a da Vinci Research Kit. Eight volunteers performed seven head movements and their data from HMI was collected to perform support vector machine (SVM) classification. Further, ten-fold cross validation was performed to optimize its parameters. Using the ten-fold cross validation result, the SVM classifier with the Gaussian kernel (sigma = 0.85) was chosen, which had an accuracy of 92.28%. An endoscopic control algorithm was developed using the SVM classification result. A peg transfer task was conducted to check the time-related effect of HMI's usability on the system, and the paired t test result showed that the task completion time was reduced. Further, the time delay of the system was measured to be 0.72 s. Graphical abstract A head-mounted master interface (HMI), which can be implemented to an existing surgical robot system, was developed to allow simultaneous surgical operation flow. The surgeon's head motion is detected through the proposed HMI and classified using a support vector machine to manipulate the endoscopic robotic arm. A classification accuracy of 92.28% was achieved. PMID- 30280332 TI - Does Sleeve Gastrectomy Cause Barrett's Oesophagus? PMID- 30280333 TI - Gastric Banding: Complications Identified by CT. AB - PURPOSE: Laparoscopic adjustable gastric banding (LAGB) used to be a common procedure at the turn of the century and is still frequently encountered on CT scans in common clinical practice. Our aim is to present the frequency and spectrum of complication associated with LAGB, as observed in CT. MATERIALS AND METHODS: After approval of our institutional review board, a retrospective search for LAGB in CT interpretations using the term "band" between December 2011 and April 2017 was conducted. CT scans were reviewed to identify complications. The findings were divided into two groups: symptomatic, in which the complications caused acute symptoms for which CT scans were conducted, and incidental, in which complications were incidentally identified. The frequency of complications was calculated. RESULTS: We identified 160 patients who underwent LAGB and performed a CT scan. Complications were identified in 69/160 (43.1%) patients, with a total of 83 findings: 47/160 (29.4%) esophageal dilatation, 13/160 (8.2%) pulmonary complications, 6/160 (3.8%) abdominal abscesses, 5/160 (3.1%) small bowel obstructions, 4/160 (2.5%) intragastric band erosions, 4/160 (2.5%) tube disconnections, 3/160 (1.9%) port site and tube course infections, and 1/160 (0.6%) small pouch bezoars. When compared with patients' referral notes, 38/83 (45.8%) of the findings were associated with acute symptoms, whereas 45/83 (54.2%) of the findings were incidental. Eighteen percent of the incidental complications were clinically important. CONCLUSION: Complications were found in 43% of CT scans of patients who underwent LAGB; less than half of the findings were symptomatic. Some of the incidentally identified complications had substantial clinical importance. PMID- 30280334 TI - Characterization of pyrolysis bio-oil derived from intermediate pyrolysis of Aegle marmelos de-oiled cake: study on performance and emission characteristics of C.I. engine fueled with Aegle marmelos pyrolysis oil-blends. AB - The present research focuses on the analyzing the characteristics of bio-oil derived from intermediate pyrolysis of Aegle marmelos (AM) seed cake and its suitability for C.I. engine adaptation. Owing to the high volatile matter content of 73.69%, Aegle marmelos biomass was selected as the feedstock for this research. The intermediate pyrolysis was carried out at 600 degrees C in a 2-kg fixed bed type pyrolysis reactor at a heating rate of 10 degrees C/min and the obtained bio-oil was characterized by different analytical methods. As per American Society for Testing and Materials (ASTM) standards, physicochemical properties of the bio-oil were tested and it was observed that bio-oil is a highly viscous fluid with low calorific value. Analysis of bio-oil through FT-IR and GC-MS examination confirmed the presence of phenol, esters, alkyl, and oxygenated compounds. The performance and emission testing of direct injection diesel engine were conducted with various bio-oil blends and the results were compared with baseline diesel fuel. The experimental results showed that the addition of bio-oil decreased BTE (%) while increasing the BSEC (MJ/kW-h). At the same time, increasing the bio-oil ratio with diesel decreases dangerous emissions such as carbon monoxide and oxides of nitrogen emissions in the engine exhaust. According to engine test result, it was suggested that up to 20% of AM bio-oil (F20) can be employed as engine fuel for better engine operating characteristics. PMID- 30280335 TI - Accumulation of heavy metals in native Andean plants: potential tools for soil phytoremediation in Ancash (Peru). AB - Metal contamination is a recurring problem in Peru, caused mainly by mine tailings from a past active mining activity. The Ancash region has the largest number of environmental liabilities, which mobilizes high levels of metals and acid drainages into soils and freshwater sources, posing a standing risk on human and environmental health. Native plant species spontaneously growing on naturally acidified soils and acid mine tailings show a unique tolerance to high metal concentrations and are thus potential candidates for soil phytoremediation. However, little is known about their propagation capacity and metal accumulation under controlled conditions. In this study, we aimed at characterizing nine native plant species, previously identified as potential hyperaccumulators, from areas impacted by mine tailings in the Ancash region. Plants were grown on mine soils under greenhouse conditions during 5 months, after which the concentration of Cd, Cu, Ni, Pb, and Zn was analyzed in roots, shoots, and soils. The bioaccumulation (BAF) and translocation factor (TF) were calculated to determine the amount of each metal accumulated in the roots and shoots and to identify which species could be better suited for phytoremediation purposes. Soil samples contained high Cd (6.50-49.80 mg/kg), Cu (159.50-1187.00 mg/kg), Ni (3.50-8.70 mg/kg), Pb (1707.00-4243.00 mg/kg), and Zn (909.00-7100.00 mg/kg) concentrations exceeding national environmental quality standards. After exposure to mine tailings, concentrations of metals in shoots were highest in Werneria nubigena (Cd, 16.68 mg/kg; Cu, 41.36 mg/kg; Ni, 26.85 mg/kg; Zn, 1691.03 mg/kg), Pennisetum clandestinum (Pb, 236.86 mg/kg), and Medicago lupulina (Zn, 1078.10 mg/kg). Metal concentrations in the roots were highest in Juncus bufonius (Cd, 34.34 mg/kg; Cu, 251.07 mg/kg; Ni, 6.60 mg/kg; Pb, 718.44 mg/kg) and M. lupulina (Zn, 2415.73 mg/kg). The greatest BAF was calculated for W. nubigena (Cd, 1.92; Cu, 1.20; Ni, 6.50; Zn, 3.50) and J. bufonius (Ni, 3.02; Zn, 1.30); BCF for Calamagrostis recta (Cd, 1.09; Cu, 1.80; Ni, 1.09), J. bufonius (Cd, 3.91; Cu, 1.79; Ni, 18.36), and Achyrocline alata (Ni, 137; Zn, 1.85); and TF for W. nubigena (Cd, 2.36; Cu, 1.70; Ni, 2.42; Pb, 1.17; Zn, 1.43), A. alata (Cd, 1.14; Pb, 1.94), J. bufonius (Ni, 2.72; Zn, 1.63), and P. clandestinum (Zn, 1.14). Our results suggest that these plant species have a great potential for soil phytoremediation, given their capability to accumulate and transfer metals and their tolerance to highly metal-polluted environments in the Andean region. PMID- 30280336 TI - Metals in a northern Nile Delta lake: water, suspended particulates, sediments, and biota. AB - Lake Edku is one of the important fishing areas in the Nile Delta. It is exposed to different quantities of serious pollutants in particular metals. To overall appraise the risk and status of metals in the lake, a comprehensive study of total concentrations of cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), and zinc (Zn) in sediments and spatial-temporal variations of these metals in the dissolved and suspended particulates, and some tissues of Tilapias niloticus, was conducted from ten sampling sites during 2016. Results showed that none of the investigated metals exceeded the limits considered as hazardous for aquatic life in water. The highest concentrations of Cd, Cu, Ni, and Zn were observed in suspended particulate matter, which may precipitate on the surface of the sediments. Potential ecological risk analysis of the majority of the investigated metals in the sediment indicated that Lake Edku posed a low ecological risk. The estimated values of all metals in tissues of Tilapia niloticus were below the international permissible limits. Moreover, the potential risk of metals to human via the consumption of Tilapia niloticus was estimated using the weekly intake levels, which was lower than the WHO's safe provisional tolerant weekly intake levels. These results prove the importance of performing measurements of contaminants in various compartments of Lake Ecosystem including sediment, biota, and suspended particulate matter for proper management. PMID- 30280337 TI - Performance of full-scale coagulation-flocculation/DAF as a pre-treatment technology for biodegradability enhancement of high strength wastepaper-recycling wastewater. AB - Paper mill wastewater leads to a serious damage on the environment owing to the high content of organic matters, suspended solids, toxic substances, and lignin. Hence, exploring new treatment technologies is the passion of environmental engineers to minimize the effluent impact on the environment and cleaner production aspects. This research focused on the performance of full-scale coagulation-fluctuation/DAF system for pre-treatment of high strength wastepaper recycling wastewater and its effect on biodegradability improvement. To optimize unit performance, optimum coagulant and flocculant doses were firstly determined by jar test without prior change and adjustment of pH in lab-scale experiments. The optimum dosages were obtained by 1500 mg L-1 polyaluminum chloride (PACl) as coagulant coupled with 40 mg L-1 cationic polyacrylamide (C-PAM) as flocculant. Percentage removals of 39 +/- 10, 6.8 +/- 3.6, 31.0 +/- 6.7, 24.0 +/- 3.8, and 33.0 +/- 20.0 were achieved for COD, sCOD, BOD5, sBOD5, and color, respectively. The average BOD5 to COD ratio after pre-treatment increased from 0.44 to 0.5, whereas the ratio of sBOD5/sCOD dropped from 0.65 to 0.53. A superior effectiveness in reduction of TSS (98.1%) and VSS (98.4%) was also achieved. The results show that the application process is able to prevent malfunction operation in the following bioreactors which is obtainable through bio treatability enhancement of pre-treated wastewater and reducing the risks of clogging and sludge washout. Attached growth processes are suggested to be applied in the further anaerobic/aerobic processes because of high proportion of soluble fraction of COD in the effluent to avoid poor floc formation and dispersed growth problems.

AB - This paper investigates dynamic variation in the morphologic distribution of dense non-aqueous phase liquids (DNAPLs), which take into account the coupled mass transfer. Experiments were carried out in a 2D tank representing a reconstructed aquifer model. DNAPL dissolution rates were investigated over a wide range of DNAPL saturations, several source configurations, and different hydraulic conditions. Morphometric indexes are presented that take into consideration further factors affecting the dissolution process. Local information regarding transport parameters related to the characteristics of the medium was obtained through a neural network and an optimization algorithm applied to experimental tracer tests. The history of DNAPL source architecture, in terms of saturation, indentation grade, and orientation, was determined by image analysis. Dissolved concentrations were registered and mass transfer rate coefficients were obtained for a wide range of source-zone configurations. A statistical analysis was performed to develop a constitutive equation that is descriptive of the mass transfer rate as a function of source-zone metric characteristics. A new empirical dissolution model using the proposed morphometric parameters is presented and compared with other models. The mass transfer correlation reported incorporates morphometric parameters and considers the complex and variable architecture of non-miscible contaminants. The proposed correlation can be used for an initial assessment of non-aqueous phase liquid (NAPL) dissolution rates over a wide range of saturation (residual and non residual) conditions and different aqueous phase velocities within the NAPL source zone.

AB - Honey has multifaceted beneficial properties, but polluted environment and unapproved apicultural practices have led to its contamination. In this study, QuEChERS method followed by chromatographic analysis by GC-MUECD/FTD and GC-MS was validated and used for determination of 24 pesticides in 100 raw honey samples from various floral origins of Northern India. Matrix-matched calibrations showed that the method was selective and linear (r2 > 0.99) with detection limit < 9.1 ng g-1 for all the studied pesticides except for monocrotophos (21.3 ng g-1). The average recoveries at different fortification levels ranged from 86.0 to 107.7% with relative standard deviation < 20%. Pesticide residues were detected in 19.0% samples, and most prevalent compounds detected were dichlorvos in 6.0% samples followed by monocrotophos (5.0%), profenofos (5.0%), permethrin (4.0%), ethion (3.0%), and lindane (3.0%) with concentrations ranging from 58.8 to 225.5, from 96.0 to 430.1, from 14.6 to 43.2, from 27.8 to 39.6, from 25.6 to 28.0, and from 19.6 to 99.2 ng g-1, respectively. Honey samples originating from cotton, sunflower, and mustard crops (33.3%) that tested positive for pesticide residues were found to be significantly higher (p < 0.05) than the honey originating from natural and fruity vegetation (13.5%). Therefore, considering the contamination of environmental compartments due to extensive application of pesticides in the study area and their potential for subsequent transfer to honey by the expeditious bees, the results of present study proclaim that honey may be used as an indicator of environmental pollution. Further, estimated daily intakes of all contaminants were found to be at levels well below their acceptable daily intakes suggesting that consumption of honeys at current levels does not pose deleterious effects on human health. However, precautionary measures should always be taken considering the customary honey feeding in infants and cumulative effect of these chemicals in the foreseeable future. PMID- 30280340 TI - Versatility of iron-rich steel waste for the removal of high arsenic and sulfate concentrations in water. AB - The aim of this work is to evaluate the application of a steel waste, basic oxygen furnace sludge (BOFS), rich in iron, to treat water contaminated with elevated arsenic and sulfate concentrations. In the first step, three doses (10, 60, and 80 g L-1) of BOFS were tested to investigate the removal of As(III) and As(V) (67 mg L-1) and sulfate (3700 mg L-1) separately from an aqueous solution. In the second step, the efficacies of BOFS (10 g L-1) and commercial ZVI (5 g L 1) were compared to simultaneously remove arsenic and sulfate. The pH of the feed solution was adjusted to 2.5 and monitored during the experiment. The use of BOFS achieved arsenic removal up to 92% and sulfate removal of nearly 40% after 72 h of contact time. Use of BOFS also increased the solution pH to 12. Similar removal levels were achieved with both BOFS and ZVI. These results confirm the potential application of BOFS to remove high arsenic and sulfate concentrations from acidic solutions. The data obtained here should be used as a basis for further studies on the remediation of acid mine drainage with high concentrations of arsenic and sulfate using an abundant and low-cost steel waste. PMID- 30280341 TI - Efficient water decontamination using layered double hydroxide beads nanocomposites. AB - Ni-Al-CO3-layered double hydroxide (LDH) with Ni:Al ratio (3:1) and their nanocomposites with alginate and chitosan beads were prepared and examined for their efficiency in removal of Cd2+ and Cu2+ ions from wastewater. Different parameters such as contact time, pH value, adsorbent weight, and heavy metal ion concentration on the removal efficiency were examined and reported. The prepared beads were examined using X-ray diffraction (XRD), TEM, SEM, and FTIR. Our results revealed a successful preparation of the LDH in rhombohedral hexognal crystal form and the alginate-LDH-chitosan beads. The optimized batch experiment conditions in ambient room temperature were found to be 2 g/L adsorbent dose, 50 mg/L initial concentration of meal, contact time of 2 h, and pH ~ 5 and 6 for removal of Cu2+ and Cd2+, respectively. The adsorption process was well fitted with Langmuir and Freundlich isotherm models (higher R2), with trivial advantage for Freundlich approach. Kinetic studies showed that the adsorption of both Cd2+ and Cu2+ followed the pseudo-second-order. The current study demonstrated that the Ni-Al-CO3 LDH and their novel alginate-chitosan-based nanocomposite could be further tailored and used as efficient adsorbents for the uptake of heavy metals from wastewater. PMID- 30280342 TI - Effects of site-specific climatic conditions on the radial growth of the lichen biomonitor Xanthoria parietina. AB - The protocols commonly applied in surveys with lichens as biomonitors of airborne trace elements require analyses of samples derived from thalli or parts of thalli grown in the last year before sampling, under the postulation that samples of the same size are of the same age. Unfortunately, the influence of ecological site specific factors on lichen growth is still largely ignored, so that samples of the same size collected in environmentally and climatically diverse sites might actually differ in age. This work aims at quantifying the influence of climatic conditions on the radial growth rates (RaGRs) of Xanthoria parietina, one of the most popular lichen biomonitors. RaGR was monitored in seven populations distributed along an altitudinal transect of 30 km in the Classical Karst (NE Italy), from 20 to 500 m above sea level. For c. 17 months, lobe growth was measured seasonally with a digital calliper, and site-specific climatic variables were monitored by means of thermo-hygrometric sensors and implemented by meteorological data. Finally, the lobe growth of X. parietina was modelled as a function of 18 environmental variables. Results revealed that thalli of relatively dry sites had significantly lower seasonal RaGR with respect to moister ones. Considering that cumulative precipitations were equally distributed along the transect, it was concluded that RaGR of X. parietina is affected negatively by high air temperatures and positively by high relative humidity. The importance of RaGR variation in lichen bioaccumulation studies is critically discussed. PMID- 30280343 TI - Biomechanical response of a submerged, rosette-forming macrophyte to wave action in a eutrophic lake on the Yungui Plateau, China. AB - Few studies have focused on the biomechanical responses of submerged, rosette forming macrophytes to wave action, water depth, or their co-occurrence in naturally eutrophic systems. The plant architecture, root anchorage strength related traits, leaf morphology, and biomechanics of Vallisneria natans inhabiting a range of water depths were examined along three transects (T1, T2, and T3) in a eutrophic lake, Lake Erhai, in Yunnan Province, China. These transects were exposed to weak wave action and hyper-eutrophication (T1), moderate wave action and eutrophication (T2), or strong wave action and eutrophication (T3). The results showed that V. natans was mainly distributed at intermediate depths, with the widest colonization depth in T1. The values of plant architecture, root anchorage strength-related traits, leaf morphology, and biomechanics were generally highest in T3 and smallest in T2. Along the depth gradient, these values were generally highest at 3.5, 2.5, and 2.5 m for the plants growing in T1, T2, and T3, respectively. These findings suggest that V. natans adopts a "tolerance" strategy to cope with the effects of strong wave action in eutrophic habitats and an "avoidance" strategy when exposed to moderate wave action in eutrophic areas. Since the absence of an avoidance strategy increases the resistance to low-light stress at the expense of increased drag forces, there is a limit to the wave action that V. natans can withstand. This study indicates that biomechanics could be important when determining the distribution pattern of V. natans in Lake Erhai. PMID- 30280346 TI - Sublethal effects of chronic exposure to CdO or PbO nanoparticles or their binary mixture on the honey bee (Apis millefera L.). AB - Cadmium and lead-based nanotechnologies are increasingly used in agricultural, industrial, and biological processes; however, potential adverse effects of nanomaterials on honey bees had not been assessed. In this study, effects of exposures to sublethal concentrations of PbO and CdO nanoparticles (NPs), either separately or in combination on honey bee (Apis mellifera) workers, were assessed. Honey bee workers were orally exposed for 9 days under laboratory conditions to sublethal concentrations (20% of LC50) of CdO (0.01 mg/ml-) and PbO (0.65 mg/ml-) NPs either separately or combined. Effects on survival, feeding rate, activity of acetylcholinesterase (AChE), and expression of selected stress related detoxifying enzymes were quantified. Survival and feeding rates decreased particularly in bees fed sugar syrup containing CdO NPs or binary mixtures of NPs of both metal oxides. Expressions of genes involved in detoxification of xenobiotics were affected by various combinations. Expression of catalase was 13.6-fold greater in bees consumed sugar syrup diet containing binary mixture of sublethal concentrations of both CdO and PbO NPs than it was in unexposed, control bees. AChE activity in heads of honey bees was inhibited by 3.8-, 3.0-, and 2.8-fold relative to control, respectively, in response to exposure to Cd or/and Pb oxide NPs. This result indicates potential neurotoxic effects of these NPs to honey bees. CdO NPs exhibited greater potency to honey bees. Overall, sublethal concentrations of CdO or/and PbO NPs resulted in detrimental effects on honeybee workers. PMID- 30280345 TI - Competitive adsorption and desorption of arsenate, vanadate, and molybdate onto the low-cost adsorbent materials alum water treatment sludge and bauxite. AB - When low-cost adsorbents are being used to remove contaminant ions (e.g. arsenate, vanadate, and molybdate) from wastewater, competitive adsorption/desorption are central processes determining their removal efficiency. Competitive adsorption of As, V, and Mo was investigated using equimolar oxyanion concentrations in single, binary, and tertiary combinations in adsorption isotherm and pH envelope studies while desorption of previously adsorbed oxyanions was examined in solutions containing single and binary oxyanion combinations. The low-cost adsorbent materials used were alum water treatment sludge (amorphous hydroxy-Al) and bauxite ore (crystalline Al oxides). Adsorption isotherm and pH envelope studies showed that Mo had only a small effect in decreasing adsorption of As and V but V and As had substantial and similar effects in reducing adsorption of the other. As had a greater effect than V in reducing adsorption of Mo and it was concluded that the affinity of oxyanions for the surfaces of water treatment sludge and bauxite followed the order As > V >> Mo. In 0.3 M NaCl electrolyte, desorption of previously adsorbed oxyanions amounted to 0.3-3.4% for V and As, and 11-20% for Mo. As had approximately four times greater effect than Mo in increasing desorption of V while V had about three times the effect of Mo in increasing desorption of As. Thus, the order of oxyanions in inducing desorption of the other oxyanions (i.e. As on V and As) was the same as that for adsorption selectivity: As > V >> Mo. Water treatment sludge was a more effective adsorbent than bauxite because it had a greater adsorption capacity for all three anions and, in addition, they were held more strongly so desorption in the background electrolyte was proportionately less. It was concluded that at similar molar concentrations, arsenate would tend to reduce adsorption of vanadate as well as displace vanadate already held on adsorbent surfaces while both anions will compete effectively with molybdate. The limiting factor for simultaneous removal of As, V, and Mo from multielement solutions by adsorption will therefore be the removal of Mo. PMID- 30280347 TI - Assessment of elemental composition and properties of copper smelter-affected dust and its nano- and micron size fractions. AB - A comprehensive approach has been developed to the assessment of composition and properties of atmospherically deposited dust in the area affected by a copper smelter. The approach is based on the analysis of initial dust samples, dynamic leaching of water soluble fractions in a rotating coiled column (RCC) followed by the determination of recovered elements and characterization of size, morphology and elemental composition of nano-, submicron, and micron par ticles of dust separated using field-flow fractionation in a RCC. Three separated size fractions of dust (<0.2, 0.2-2, and >2 MUm) were characterized by static light scattering and scanning electron microscopy, whereupon the fractions were analyzed by ICP AES and ICP-MS (after digestion). It has been evaluated that toxic elements, which are characteristics for copper smelter emissions (As, Cu, Zn), are accumulated in fraction >2 MUm. At the same time, up to 2.4, 3.1, 8.2, 6.7 g/kg of As, Cu, Zn, Pb, correspondently, were found in nanoparticles (<0.2 MUm). It has been also shown that some trace elements (Sn, Sb, Ag, Bi, and Tl) are accumulated in fraction <0.2, and their content in this fraction may be one order of magnitude higher than that in the fraction >2 MUm, or the bulk sample. It may be assumed that Sn, Sb, Ag, Bi, Tl compounds are adsorbed onto the finest dust particles as compared to As, Cu, Zn compounds, which are directly emitted from the copper smelter as microparticles. PMID- 30280344 TI - Association of benzene exposure with insulin resistance, SOD, and MDA as markers of oxidative stress in children and adolescents. AB - Benzene is a ubiquitous environmental pollutant with various health effects. It is reported that benzene exposure might be associated with insulin resistance in elderly adults. The aim of this study is to investigate the association between urinary benzene metabolite, trans, trans-muconic acid (t,t-ma) and markers of oxidative stress and insulin resistance in children and adolescents. This cross sectional study was conducted in 2017 among 86 children and adolescents, aged 6 18 years, living in Isfahan, Iran. t,t-ma was measured as urinary benzene metabolite and homeostasis model assessment (HOMA-IR) was determined as an index of insulin resistance. Moreover, malondialdehyde (MDA) and superoxide dismutase (SOD) were assessed as oxidative stress markers. We found significant association between insulin resistance, fasting blood glucose, and fasting blood insulin with t,t-ma (p values = 0.002, 0.03, and 0.001, respectively). Results of this study indicate that benzene metabolite in higher concentrations in comparison with lower concentrations is associated with increased risk of insulin resistance. Moreover, after adjustment for age, sex, and household passive smoking, statistically significant increase were documented in SOD and MDA (4.49- and 3.54 fold, respectively) in intermediate levels of t,t-ma vs. low levels of t,t-ma (p values = 0.01 and 0.034, respectively). To the best of our knowledge, this is the first study in its kind in the pediatric age group. It showed that benzene exposures, even in environmental levels, might be associated with insulin resistance and oxidative stress in children and adolescents. Further longitudinal studies are necessary to assess the clinical impacts of this finding. PMID- 30280348 TI - The legacy of pesticides and POPs stockpiles-a threat to health and the environment. PMID- 30280349 TI - Interactions Between Biological Products and Product Packaging and Potential Approaches to Overcome Them. AB - Biological products such as protein-based biopharmaceuticals are playing an important role in the healthcare and pharmaceutical industry. The interaction between biological products and packaging materials has become the focus of many studies since it can reduce the effectiveness of biological products. These interactions are heavily influenced by the surface properties and physicochemical nature of the therapeutic agents and the packaging materials. Therefore, it is critical to understand the interactions between packaging materials and biological products in order to design biocompatible packaging materials and develop approaches to minimize adverse interactions. We describe the interactions that occur when using several common packaging materials, including glass and polymer. We discuss the interaction between these materials and biological products such as blood, blood derivatives, recombinant proteins, monoclonal antibodies, and gene therapeutics. We also summarize approaches for overcoming these interactions. Understanding the interactions between biological materials and packaging materials is critical for the development of novel packaging materials that improve the safety of pharmaceutical products. PMID- 30280350 TI - Nanocarrier-Based Combination Chemotherapy for Resistant Tumor: Development, Characterization, and Ex Vivo Cytotoxicity Assessment. AB - A folic acid-conjugated paclitaxel (PTX)-doxorubicin (DOX)-loaded nanostructured lipid carrier(s) (FA-PTX-DOX NLCs) were prepared by using emulsion-evaporation method and extensively characterized for particle size, polydispersity index, zeta potential, and % entrapment efficiency which were found to be 196 +/- 2.5 nm, 0.214 +/- 0.04, +23.4 +/- 0.3 mV and 88.3 +/- 0.2% (PTX), and 89.6 +/- 0.5% (DOX) respectively. In vitro drug release study of optimized formulation was carried out using dialysis tube method. FA-conjugated PTX-DOX-loaded NLCs showed 75.6 and 78.4% (cumulative drug release) of PTX and DOX respectively in 72 h in PBS (pH 7.4)/methanol (7:3), while in the case of FA-conjugated PTX-DOX-loaded NLCs, cumulative drug release recorded was 80.4 and 82.8% of PTX and DOX respectively in 72 h in PBS (pH 4.0)/methanol (7:3). Further, the formulation(s) were evaluated for ex vivo cytotoxicity study. The cytotoxicity assay in doxorubicin-resistant human breast cancer MCF-7/ADR cell lines revealed lowest GI50 value of FA-D-P NLCs which was 1.04 +/- 0.012 MUg/ml, followed by D-P NLCs and D-P solution with GI50 values of 3.12 +/- 0.023 and 3.89 +/- 0.007 MUg/ml, respectively. Findings indicated that the folic acid-conjugated PTX and DOX co loaded NLCs exhibited lower GI50 values as compared to unconjugated PTX and DOX co-loaded NLCs; thus, they have relatively potential anticancer efficacy against resistant tumor. PMID- 30280351 TI - Intratumoral Injection Administration of Irinotecan-Loaded Microspheres: In Vitro and In Vivo Evaluation. AB - To reduce the toxic and side effects of intravenous chemotherapeutic drugs on the tumor-patients, the aims of this study were to design and study intratumor administrated irinotecan-loaded PLGA microspheres (CPT-11-PLGA-MS) in vitro and in vivo according to the structure characteristics of CPT-11. PLGA microspheres containing irinotecan were prepared by emulsion solvent evaporation method and evaluated in terms of their morphology, particle size analysis, in vitro drug release, drug retention and leakage studies in vivo, and pharmacodynamics studies. The CPT-11-PLGA-MS were spherical with mean size of 9.29 +/- 0.02 MUm, and average encapsulation efficiency were measured of 77.97 +/- 1.26% along with the average drug loading of 7.08 +/- 0.11%. DSC results indicated that the drug existed in the phase of uncrystallization in the microspheres. The formulation of CPT-11-PLGA-MS could prolong the in vitro drug release to 16 days following Weibull equation. In CPT-11-PLGA-MS after intratumor injection administration was significantly improved. The results demonstrated that the slow-sustained release of CPT-11-PLGA-MS in tumor tissue after intratumor injection of microspheres can reduce the drug leakage to the circulation system, maintain the drug retention, and improve the therapeutic effect, which could become a promising drug delivery system for CPT-11 and could maintain the most effective concentration at the target site to maximum limit. PMID- 30280352 TI - Comparing a Statistical Model and Bayesian Approach to Establish the Design Space for the Coating of Ciprofloxacin HCl Beads at Different Scales of Production. AB - The primary objective of this study was to compare two methods for establishing a design space for critical process parameters that affect ethylcellulose film coating of multiparticulate beads and assess this design space validity across manufacturing scales. While there are many factors that can affect film coating, this study will focus on the effects processing conditions have on the quality and extent of film formation, as evaluated by their impact coating yield and drug release. Ciprofloxacin HCl layered beads were utilized as an active substrate core, ethylcellulose aqueous dispersion as a controlled release polymer, and triethyl citrate as a plasticizer. Thirty experiments were conducted using a central composite design to optimize the coating process and map the response surface to build a design space using either statistical least squares or a Bayesian approach. The response surface was fitted using a linear two-factor interaction model with spraying temperature, curing temperature, and curing time as significant model terms. The design spaces established by the two approaches were in close agreement with the statistical least squares approach being more conservative than the Bayesian approach. The design space established for the critical process parameters using small-scale batches was tested using scale-up batches and found to be scale-independent. The robustness of the design space was confirmed across scales and was successfully utilized to establish process signature for the coating process. PMID- 30280353 TI - Enhanced Oral Bioavailability of Chlormadinone Acetate through a Self Microemulsifying Drug Delivery System for a Potential Dose Reduction. AB - Chlormadinone acetate (CMA) is a derivative of the naturally secreted hormone progesterone and exhibits reliable contraceptive and non-contraceptive benefits. Although the marketed product of CMA as oral tablets under the trade name Belara(r) has been highly successful, there is still room for further improvements in oral bioavailability and a reduction in the clinical dose to decrease related adverse effects. In the current study, a CMA-based self microemulsifying drug delivery system (SMEDDS) was developed using 32% ethyl oleate as an oil phase, 40% Tween-80 as a surfactant, and 12% Transcutol P combined with 16% PEG400 as a cosurfactant, resulting in spherical droplets with a z-average particle size of 38.92 nm and an average zeta potential of - 3.18 mv. The in vitro release rate of CMA from CMA-SMEDDS in different media (distilled water, HCl solution at pH 1.2, phosphate buffers at pH 4.5 and pH 6.8) was significantly faster than that from Belara(r) in the first 15 min. A pharmacokinetic study in rats showed that the Cmax and AUC of CMA-SMEDDS were significantly higher (P < 0.01) than those of Belara(r), with a 1.98-fold increase in oral bioavailability. In comparison with Belara(r), the developed CMA SMEDDS showed promising release profiles both in vitro and in vivo, which could potentially be useful in enhancing oral bioavailability and reducing the clinical dose of CMA. PMID- 30280354 TI - Preparation and Characterization of an Oral Vaccine Formulation Using Electrosprayed Chitosan Microparticles. AB - Chitosan particles loaded with the antigen ovalbumin (OVA) and the adjuvant Quil A were produced by electrospray, using mixtures of water/ethanol/acetic acid as a solvent. Three different chitosans designed as HMC+70, HMC+85, and HMC+90 (called as 705010, 855010, and 905010) were tested and its efficacy to be used in oral vaccine delivery applications was investigated. The morphology, size, and zeta potential of the produced particles were investigated, together with the encapsulation efficiency and release of OVA from the three chitosan formulations. Moreover, the mucoadhesion and cytotoxicity of the chitosan microparticles was examined. All the three formulations with OVA and Quil-A were in the micrometer size range and had a positive zeta potential between 46 and 75 mV. Furthermore, all the three formulations displayed encapsulation efficiencies above 80% and the release of OVA over a period of 80 h was observed to be between 38 and 47%. None of the developed formulations exhibited high mucoadhesive properties, either cytotoxicity. The formulation prepared with HMC+70, OVA, and Quil-A had the highest stability within 2 h in buffer solution, as measured by dynamic light scattering. The electrosprayed formulation consisting of HMC+70 with OVA and Quil A showed to be the most promising as an oral vaccine system. PMID- 30280355 TI - Aggregate Elasticity and Tabletability of Molecular Solids: a Validation and Application of Powder Brillouin Light Scattering. AB - Describing the elastic deformation of single-crystal molecular solids under stress requires a comprehensive determination of the fourth-rank stiffness tensor (Cijkl). Single crystals are, however, rarely utilized in industrial applications, and thus averaging techniques (e.g., the Voigt or Reuss approach) are employed to reduce the Cijkl (or its inverse Sijkl) to polycrystalline aggregate mechanical moduli. With increasing elastic anisotropy, the Voigt and Reuss-averaged aggregate moduli can diverge dramatically and, provided that drug molecules almost exclusively crystallize into low-symmetry space groups, warrants a significant need for accurate aggregate mechanical moduli. This elasticity data, which currently is largely absent for pharmaceutical materials, is expected to aid understanding how materials respond to direct compression and tablet formation. Powder Brillouin light scattering (p-BLS) has recently demonstrated facile access to porosity-independent, aggregate mechanical moduli. In this study, we extend our previous p-BLS model for obtaining mechanical properties and validate our approach against a broad library of molecular solids with diverse intermolecular interaction topologies and with previously determined Cijkl which permits benchmarking our results. Our Young's and shear moduli determined with p BLS strongly correlate, with limited bias (i.e., a near 1:1 relation), with the Voigt-averaged Young's and shear moduli determined using the Cijkl. Through follow-on tabletability studies, we introduce initial classifications of tabletability behavior based on the results of our p-BLS studies and the apparent elastic anisotropy. With further development, this approach represents a robust and novel method to potentially identify materials for optimum tabletability at early developmental stages.

A design of experiments (DoE) approach was used to perform a set of 15 experiments, varying independent variables (feed rate, input temperature, and screw speed) within a design space. Redispersibility index (RDI), moisture content, and process yield constituted the critical quality attributes (CQAs) of the experimental design. Regression analysis and ANOVA were employed to identify and estimate significant main effects and two-way interactions, and model the process of HME drying for predictive purposes. The optimized HME-dried end product was characterized for physicochemical properties using differential scanning calorimetry (DSC), X-ray powder diffractions (XRPD), polarized light microscopy (PLM), Fourier transform infrared spectroscopy (FTIR), and in vitro dissolution studies. The statistical analysis reveals feed rate and input temperature as significant independent variables, critically influencing RDI and moisture content of solidified end product. The model developed for process yield was insignificant at a p-value of 0.05. The API retained its amorphous nature after the extrusion process which was confirmed using DSC and XRPD techniques. PLM was unsuitable to differentiate and determine crystallinity of drug moiety in the presence of a semi-crystalline bulking agent, microcrystalline cellulose (MCC). In vitro dissolution study depicted solubility and dissolution enhancement for HME-dried amorphous nanosuspension in both the dissolution media which can be attributed to amorphous nature of nanosized drug particles. A well-designed study implemented by DoE aided in developing a robust and novel HME technique to dry aqueous nanosuspension.

AB - Gastroesophageal reflux disease (GERD) is an esophageal injury occurred when the stomach contents reflux abnormally into the esophagus. GERD complications include esophageal adenocarcinoma. Mosapride (MOS) is a safe prokinetic agent potentially used to treat GERD. Yet, its low solubility and bioavailability due to extensive first-pass metabolism limits its applications. This study aimed to formulate MOS nanostructured lipid carriers (MOS-NLCs) via the intranasal route to improve its bioavailability. Melt-emulsification low temperature-solidification technique using 23 full factorial design was adopted to formulate MOS-NLCs. Eight formulae were prepared and assessed in terms of entrapment efficiency (%EE), particle size, and in vitro release. Glycerol addition significantly reduced the particle sizes and improved %EE and %drug released. Surface modification using chitosan was applied. The optimized MOS surface-modified nanostructured lipid carriers (MOS-SMNLCs-F7)(stearic acid, 4% glycerol, 0.5% LuterolF127, 0.5% chitosan) showed low particle size 413.8 nm +/- 11.46 nm and high %EE 90.19% +/- 0.06% and a threefold increase in permeation of MOS with respect to the drug suspension. MOS-SMNLCs (F7) was also evaluated for its bioavailability compared with drug suspension and commercial product. Statistical analysis revealed a significant increase in gastric emptying rate to be 21.54 +/- 1.88 contractions/min compared with10.02 +/- 0.62 contractions/min and 8.9 +/- 0.72 contractions/min for drug suspension and oral marketed product respectively. Pharmacokinetic studies showed 2.44-fold rise in bioavailability as compared to MOS suspension and 4.54-fold as compared to the oral marketed product. In vitro/in vivo studies proven to level A correlation between in vitro permeation through sheep nasal mucosa and in vivo absorption. Therefore, MOS-SMNLCs could be considered a step forward towards enhancing the clinical efficacy of Mosapride.

AB - The current study was aimed to develop an amphiphilic drug-lipid nano-complex of rutin:egg phosphatidylcholine (EPC) to enhance its poor absorption and bioavailability, and investigated the impact of the complex on hepatoprotective and antioxidant activity. Rutin nano-complexes were prepared by solvent evaporation, salting out and lyophilisation methods and compared for the complex formation. For the selected lyophilisation method, principal solvent DMSO, co solvent (t-butyl alcohol) and rutin:EPC ratios (1:1, 1:2 and 1:3) were selected after optimisation. The properties of the nano-complexes such as complexation, thermal behaviour, surface morphology, molecular crystallinity, particle size, zeta potential, drug content, solubility, in vitro stability study, in vitro drug release, in vitro and in vivo antioxidant study, in vivo hepatoprotective activity and oral bioavailability/pharmacokinetic studies were investigated. Rutin nano-complexes were developed successfully via the lyophilisation method and found to be in nanometric range. Rutin nano-complexes significantly improved the solubility and in vitro drug release, and kinetic studies confirmed the diffusion-controlled release of the drug from the formulation. The nano-complex showed better antioxidant activity in vitro and exhibited well in vitro stability in different pH media. The in vivo study showed better hepatoprotective activity of the formulation compared to pure rutin at the same dose levels with improved oral bioavailability. Carbon tetrachloride (CCl4)-treated animals (group II) failed to restore the normal levels of serum hepatic marker enzymes and liver antioxidant enzyme compared to the nano-complex-treated animals. The results obtained from solubility, hepatoprotective activity and oral bioavailability studies proved the better efficacy of the nano-complex compared to the pure drug.

AB - Film coating thickness of minitablets was estimated in-line during coating in a fluid-bed equipment by means of visual imaging. An existing, commercially available image acquisition system was used for image acquisition, while dedicated image analysis and data analysis methods were developed for this purpose. The methods were first tested against simulated minitablet's images and after that examined on a laboratory-scale fluid-bed Wurster coating process. An observation window cleaning mechanism was developed for this purpose. Six batches of minitablets were coated in total, using two different dispersions, where for the second dispersion coating endpoint was determined based on the in-line measurement. Coating thickness estimates were calculated from the increasing size distributions of the minitablet's major and minor lengths, assessed from the acquired images. Information on both the minitablet's average band and average cap coating thicknesses was obtained. The in-line coating thickness estimates were compared to the coating thickness weight gain calculations and the optical microscope measurements as a reference method. Average band coating thickness estimate was found the most accurate in comparison to microscope measurements, with root mean square error of 1.30 MUm. The window cleaning mechanism was crucial for the accuracy of the in-line measurements as was evident from the corresponding decrease of the root mean square error (9.52 MUm, band coating thickness). The presented visual imaging approach exhibits accuracy of at least 2 MUm and is not susceptible to coating formulation or color variations. It presents a promising alternative to other existing techniques for the in-line coating thickness estimation. PMID- 30280360 TI - Can we now say that commonalities between restless leg syndrome and migraine exist? AB - The recent manuscript by Xinglong Yang and colleagues provided the first relatively reliable estimate of restless leg syndrome (RLS) prevalence among migraine sufferers, which was estimated at 19% (95% CI 14-24%). The implications of the association between the two conditions are wide, and call for further action aimed to address common disease mechanism-associated conditions such as sleep-related ones and associated burden.

AB - OBJECTIVE: Osmophobia and headache triggered by odors are commonly seen in migraine, and these are symptoms that differentiate migraine from other primary headaches. Since these odor-related symptoms are disease-specific, we aimed to measure the volume of olfactory bulb and depth of olfactory sulcus in migraine patients. PATIENTS AND METHOD: A total of 93 subjects, consisting of 62 episodic migraine (32 with osmophobia, 30 without osmophobia) patients and 31 healthy controls, were included in this study. Diagnosis and classification of migraine were performed according to the beta version criteria of International Classification of Headache Disorders (ICHD-3 Beta version). Beck depression and beck anxiety inventory were applied to the patients, and the measurement of bilateral olfactory bulb volume (OBV) and olfactory sulcus depth (OSD) was performed manually in the brain magnetic resonance imaging (MRI). RESULTS: More significantly in the left OBV, low OBV has been determined in migraine patients compared to the control group (p < 0.001, p = 0.020). When migraine patients with or without osmophobia were compared to the control group; OBV was determined to be the lowest in migraine group with osmophobia, and left-weighted bilateral OBV was determined to be low (p < 0.001, p = 0.046). No statistically significant difference was determined between groups in OSD measurements (p = 0.646, p = 0.490). CONCLUSION: Left-weighted bilateral OBV atrophy determined in migraine patients may be guiding for the clarification of migraine pathophysiology and enlightening of the relation between migraine and odor. PMID- 30280363 TI - Having Siblings is Associated with Better Social Functioning in Autism Spectrum Disorder. AB - Sibling relationships play a unique developmental role, especially in emotional and social domains. In autism spectrum disorder (ASD), social-communication skills are often impaired in comparison to typical development. Therefore, studying siblings' effects on social skills of the child with ASD is important. This retrospective study examined how autism severity and functioning were affected by having older and younger sibling/s, the sex of the index child and of the sibling, and the number of siblings. The study population included 150 participants with ASD (mean age = 4:0 +/- 1:6), divided into three equal groups (no sibling, older and younger siblings), matched for cognitive level. The evaluation included neurological and standardized behavioral, cognitive, and functional assessments. Children with ASD with older siblings showed less severe social interaction deficits and better social adaptive skills than only children. No significant differences in autism severity and adaptive functioning were noted between the group with younger siblings and the other groups. The more older siblings the affected child had, the better their social functioning. The sex of the participants with ASD and that of the sibling were not associated with social functioning. Social interaction deficits, the presence of older or younger siblings for children with ASD, and higher cognitive ability contributed significantly to the explained variance (48.9%) in social adaptive skills. These findings emphasize that older siblings positively influence the social skills of their younger sibling with ASD. The effect of typically developing younger siblings was modest and seen only in children with ASD and better cognition. PMID- 30280364 TI - Children Sleep and Antisocial Behavior: Differential Association of Sleep with Aggression and Rule-Breaking. AB - There is a strong relationship between sleep and behavioral problems. These findings are often interpreted via environmental explanations, such that poor sleep directly exacerbates or causes symptoms of aggression and behavior problems. However, there are other possible explanations, such that the genes predicting poor sleep also predict aggression or rule-breaking. The current study sought to elucidate the origin of this relationship. The sample was composed of 1030 twin pairs (426 monozygotic and 604 dizygotic). The sample was 51.3% male with a mean age of 8.06 years (range 6-11.96; SD = 1.45). Aggression, rule breaking and sleep were assessed through the Child Behavior Checklist (CBCL). We fitted bivariate Cholesky genetic models to the data, decomposing the variance within, and the covariance among, aggression, rule-breaking, and sleep functioning into their genetic and environmental components. Genetic correlations between all sleep variables and aggression were significant and moderate to large in magnitude, but mostly small and non-significant between sleep and rule breaking. We did not find evidence of a causal or environmental relationship between the majority of sleep variables and aggression, but rather clear evidence of genetic pleiotropy. However, the pattern of associations between rule-breaking and sleep measures was less consistent. Aggression and rule-breaking appear to be differentially associated with sleep. PMID- 30280365 TI - Using Early Childhood Behavior Problems to Predict Adult Convictions. AB - The current study examined whether teacher and parent ratings of externalizing behavior during kindergarten and 1st grade accurately predicted the presence of adult convictions by age 25. Data were collected as part of the Fast Track Project. Schools were identified based on poverty and crime rates in four locations: Durham, NC, Nashville, TN, Seattle, WA, and rural, central PA. Teacher and parent screening measures of externalizing behavior were collected at the end of kindergarten and 1st grade. ROC curves were used to visually depict the tradeoff between sensitivity and specificity and best model fit was determined. Five of the six combinations of screen scores across time points and raters met both the specificity and sensitivity cutoffs for a well-performing screening tool. When data were examined within each site separately, screen scores performed better in sites with high base rates and models including single teacher screens accurately predicted convictions. Similarly, screen scores performed better and could be used more parsimoniously for males, but not females (whose base rates were lower in this sample). Overall, results indicated that early elementary screens for conduct problems perform remarkably well when predicting criminal convictions 20 years later. However, because of variations in base rates, screens operated differently by gender and location. The results indicated that for populations with high base rates, convictions can be accurately predicted with as little as one teacher screen taken during kindergarten or 1st grade, increasing the cost-effectiveness of preventative interventions. PMID- 30280367 TI - PF-05280014: A Trastuzumab Biosimilar. AB - PF-05280014 (TrazimeraTM) is the fourth biosimilar of the reference anti-HER2 antibody trastuzumab to be approved in the EU. It is approved for use in all indications for which reference trastuzumab is approved, including HER2-positive metastatic or early breast cancer and metastatic gastric cancer. PF-05280014 has similar physicochemical and pharmacodynamic properties to those of reference trastuzumab, and the pharmacokinetic similarity of the agents has been shown in women with metastatic or early HER2-positive breast cancer and healthy male volunteers. The efficacy of PF-05280014 was equivalent to that of reference trastuzumab in women with HER2-positive metastatic breast cancer and was comparable to that of reference trastuzumab in those with HER2-positive early breast cancer. The immunogenicity, tolerability and safety profiles of PF 05280014 were similar to those of reference trastuzumab. The role of reference trastuzumab in the management of HER2-positive breast and gastric cancers is well established and PF-05280014 provides an effective biosimilar alternative for patients requiring trastuzumab therapy. PMID- 30280366 TI - Gasdermin Family: a Promising Therapeutic Target for Stroke. AB - Stroke is one of the leading causes of death worldwide and therapies are limited. According to the mechanisms underlying stroke, direct cell demise, destruction of organelles, blood-brain barrier disruption, neuroinflammation are potential therapeutic targets. Gasdermin (GSDM) family is a series of recently discovered proteins, which acts as the executor of pyroptosis and protagonist of membrane pore formation. It can be cleaved by inflammatory caspases that are activated by multi-protein complexes, named as inflammasomes, and divided into two domains. The N-terminal domain interacts with lipid localized in the plasma membrane as well as organelle membrane and perforates them. After the formation of pores, the dysfunctional structures suffer lytic death and their contents are released. In this review, we discuss the biological characteristic of GSDM family and their possible roles in stroke-induced brain injury, and based on the review, we hypothesize the feasibility of using GSDMs as a potential target for stroke treatment. PMID- 30280368 TI - The efficacy and safety of total glucosides of peony in the treatment of primary Sjogren's syndrome: a multi-center, randomized, double-blinded, placebo controlled clinical trial. AB - To evaluate the efficacy and safety of total glucosides of peony (TGP) in adults with primary Sjogren's syndrome (pSS). A multi-center, randomized, double blinded, placebo-controlled study was conducted between March 2012 and July 2014 at ten Chinese hospitals. In total, 320 pSS patients-classified according to the 2002 American-European Consensus Group Criteria-were randomized (2:1 ratio) to receive TGP(600 mg, tid) in the TGP group or placebo for 24 weeks in the placebo group. Study personnel, investigators, and patients were blinded to the treatment grouping. The primary endpoint was the improvement of EULAR Sjogren's Syndrome Patient Reported Index (ESSPRI) at week 24. The secondary endpoints were dry eyes/mouth/skin/nose/throat/vagina visual analogue scale (VAS), pain and discomfort VAS, fatigue VAS, mental discomfort VAS, patient global assessment (PGA), EULAR Sjogren's Syndrome Disease Activity Index (ESSDAI), Schirmer's test, basal/stimulated salivary flow-rate values, and erythrocyte sedimentation rate (ESR). All adverse events were recorded during the trial period. ESSPRI improved more in the TGP than the placebo group (p < 0.001). Dry eyes/throat/vagina VAS, fatigue VAS, mental discomfort VAS, PGA, Schirmer's test, and ESR also improved more in the TGP group than in the placebo group (all p < 0.05). Stimulated salivary flow-rate values increased in the TGP group at week 12 but not at week 24. Adverse events in TGP group were 10.9%. TGP can alleviate some dryness symptoms as well as disease activity in pSS patients over 24 weeks. TGP was well tolerated by study subjects. TGP seems to be an effective and safe treatment for pSS. PMID- 30280370 TI - Introduction of a uniform record keeping practice for rheumatology clinics in Sri Lanka-an ILAR project. AB - In Sri Lanka, record keeping in rheumatology clinics is purely paper-based. Clinic record books are given to patients, and the hospital does not retain clinical data. Different clinics and different rheumatology specialists practice different formats of record keeping in Sri Lanka. This project was aimed to develop a uniform record keeping system which can be used in all government rheumatology clinics in Sri Lanka. Project was carried out in two phases. First phase was carried out in seven rheumatology clinics to identify deficiencies in existing practice of record keeping in rheumatoid arthritis (RA), spondyloarthritis (SPA), and systemic lupus erythematosus (SLE). Second phase was to develop new clinic documents and a computer-based system, using the findings of the first phase. Recording of classification criteria at the time of diagnosis was 40.6% for RA and 90.3% for SLE. Initial clinical notes were not available in 18.3% of RA patients. Recording of individual classification criteria in SPA was ranged between 10% and70%, and it was 100% for arthritis. During second phase, new paper-based and computer-based record keeping systems were developed. Existing practice of record keeping is incomplete, especially in RA and SPA. The necessity of new, uniform record keeping system was recognized. Paper-based and computer-based record keeping systems acceptable to specialist rheumatologists, medical officers, and the Ministry of Health were developed and tested. The newly developed paper-based system is being used nationally while the electronic system is yet to introduced. PMID- 30280369 TI - Chronic lung disease in U.S. Veterans with rheumatoid arthritis and the impact on survival. AB - Assess the impact of chronic lung diseases (CLD) on survival in rheumatoid arthritis (RA). Among participants in the Veterans Affairs Rheumatoid Arthritis (VARA) Registry, a prospective cohort of U.S. Veterans with RA, we identified CLD and cardiovascular disease (CVD) using administrative and registry data. Demographics, smoking status, RA characteristics including Disease Activity Score in 28 joints (DAS28), and disease-modifying anti-rheumatic drug (DMARD) use were obtained from registry data, which were linked to the National Death Index to obtain vital status. We evaluated associations of CLD with survival using the multivariable Cox regression models. Among a large (n = 2053), male-predominant (91%) RA cohort, 554 (27%) had CLD at enrollment. Mortality risk was increased 1.51-fold (95% CI 1.26-1.81) in RA patients with CLD after multivariable adjustment, a risk that was similar to that observed with CVD (HR CLD alone 1.46 [1.03-2.06]; CVD alone 1.62 [1.35-1.94]). Survival was significantly reduced in those with interstitial lung disease (ILD) as well as other forms of CLD. Mortality risk with methotrexate and biologic use was not different in those with CLD compared to those without (p interaction >= 0.15) using multiple exposure definitions and propensity score adjustment. Mortality risk is significantly increased in RA patients with CLD. This risk is attributable not only to ILD but also to other chronic lung conditions and does not appear to be substantially greater in those receiving methotrexate or biologic therapies. Comorbid lung disease should be targeted as a means of improving long-term outcomes in RA. PMID- 30280372 TI - Cobalt ions stimulate a fibrotic response through matrix remodelling, fibroblast contraction and release of pro-fibrotic signals from macrophages. AB - Many studies report the adverse responses to metal-on-metal (MoM) hip prostheses, with tissues surrounding failed MoM hip prostheses revealing abundant tissue necrosis and fibrosis. These local effects appear to be initiated by metal ions released from the prosthesis causing the secretion of inflammatory mediators. However, little is known about the effect of the metal ions on tissue remodelling and pseudotumor formation, which are also associated with the failure of MoM hip prostheses. The peri-prosthetic soft tissue masses can lead to pain, swelling, limited range of joint movement and extensive tissue lesion. To elucidate this cellular response, a multidisciplinary approach using both two- and three dimensional (2D and 3D) in vitro culture systems was employed to study the effects of Co2+ and Cr3+ on human fibroblast activation and mechanobiology. Co2+ induced a fibrotic response, characterised by cytoskeletal remodelling and enhanced collagen matrix contraction. This was associated with increased cell stiffness and contractile forces as measured by atomic force microscopy and traction force microscopy, respectively. These effects were triggered by the generation of reactive oxygen species (ROS). Moreover, this fibrotic response was enhanced in the presence of macrophages, which increased the prevalence of a smooth muscle actin (a-SMA)-positive fibroblasts and collagen synthesis. Cr3+ did not show any significant effect on fibroblast activation. Co2+ promoted matrix remodelling by fibroblasts that was further enhanced by macrophage signalling. Use of alternative implant materials or manipulation of this fibrotic response could provide an opportunity for enhancing the success of prostheses utilising CoCr alloys. PMID- 30280373 TI - Circumaortic left renal vein (circumaortic renal collar) associated with the presence of vascular anomalies: a case series and review of literature. AB - Renal vessels exhibit a high degree of anatomical variations in terms of their number, level of origin, diameter and topographical relationships. In particular, it applies to the left renal vein which can take retroaortic or even circumaortic placement. Anatomical variations of the left renal vein may be of great clinical significance, particularly in the case of renal transplantation, retroperitoneal surgery as well as vascular or diagnostic procedures. Thus, the aim of this report was to present a complete anatomical description of two cases of the circumaortic left renal vein (circumaortic renal collar) co-existing with the presence of various vascular anomalies. In the first case, the circumaortic renal collar was connected via a large anastomosis with the hemiazygos vein and was associated with the presence of the supernumerary left renal artery located below the main left renal artery. In the second case, the circumaortic renal collar was accompanied by the renal artery dividing close to its origin. Moreover, in the latter case, the fusiform aneurysm of the abdominal aorta was observed. In both cases, the circumaortic left renal vein began as a single and short trunk. On its further course, the initial segment of the circumaortic left renal vein was divided into two limbs - anterior (anterior left renal vein) and posterior (posterior left renal vein). Both anterior and posterior limb of the circumaortic left renal vein opened into the inferior vena cava. PMID- 30280374 TI - Assessment of paranasal sinus parameters according to ancient skulls' gender and age by using cone beam computed tomography. AB - BACKGROUND: The aim of this study was to determine whether paranasal sinus dimensions and volume can be useful to identify gender and age estimation for ancient skulls using cone beam computed tomography (CBCT) images. MATERIALS AND METHODS: CBCT scans of 32 ancient skulls from app. 1000 years of age were included in this retrospective study. The gender and age estimation of the skulls were made by an independent anthropologist which was served as the gold standard. Paranasal sinuses dimensions (width and height) and volumes of each sinus were measured from the CBCT data set that were linked to the 3D rendering software (Anatomage, Invivo 5.2). All measurements were performed by an independent observer. Intra-observer analysis was made. Mann-Whitney test and Kruskal-Wallis tests were used to compare paranasal sinus parameters in terms of age estimation and gender (p<0.05). RESULTS: The results demonstrated no statistically significant difference between measurements (p<0.05). The measurements were found to be high reproducibility. The mean volumes for frontal and sphenoid sinus were found to be higher in males. The distance from anterior-posterior wall of sphenoid sinus in axial sections is larger in males (p>0.05). The frontal sinus width and volume increased statistically with age above 60 yrs. of age (p>0.05). CONCLUSIONS: The paranasal volume and dimensions measurements from CBCT data can be a promising technique to determine gender and age estimation from ancient skulls because of its lower voxel sizes and higher resolution. PMID- 30280371 TI - Switchable DNA-origami nanostructures that respond to their environment and their applications. AB - Structural DNA nanotechnology, in which Watson-Crick base pairing drives the formation of self-assembling nanostructures, has rapidly expanded in complexity and functionality since its inception in 1981. DNA nanostructures can now be made in arbitrary three-dimensional shapes and used to scaffold many other functional molecules such as proteins, metallic nanoparticles, polymers, fluorescent dyes and small molecules. In parallel, the field of dynamic DNA nanotechnology has built DNA circuits, motors and switches. More recently, these two areas have begun to merge-to produce switchable DNA nanostructures, which change state in response to their environment. In this review, we summarise switchable DNA nanostructures into two major classes based on response type: molecular actuation triggered by local chemical changes such as pH or concentration and external actuation driven by light, electric or magnetic fields. While molecular actuation has been well explored, external actuation of DNA nanostructures is a relatively new area that allows for the remote control of nanoscale devices. We discuss recent applications for DNA nanostructures where switching is used to perform specific functions-such as opening a capsule to deliver a molecular payload to a target cell. We then discuss challenges and future directions towards achieving synthetic nanomachines with complexity on the level of the protein machinery in living cells.

PMID- 30280376 TI - GRIN2D variants in three cases of developmental and epileptic encephalopathy. AB - N-methyl-d-aspartate (NMDA) receptors are glutamate-activated ion channels that are widely distributed in the central nervous system and essential for brain development and function. Dysfunction of NMDA receptors has been associated with various neurodevelopmental disorders. Recently, a de novo recurrent GRIN2D missense variant was found in two unrelated patients with developmental and epileptic encephalopathy. In this study, we identified by whole exome sequencing novel heterozygous GRIN2D missense variants in three unrelated patients with severe developmental delay and intractable epilepsy. All altered residues were highly conserved across vertebrates and among the four GluN2 subunits. Structural consideration indicated that all three variants are probably to impair GluN2D function, either by affecting intersubunit interaction or altering channel gating activity. We assessed the clinical features of our three cases and compared them to those of the two previously reported GRIN2D variant cases, and found that they all show similar clinical features. This study provides further evidence of GRIN2D variants being causal for epilepsy. Genetic diagnosis for GluN2-related disorders may be clinically useful when considering drug therapy targeting NMDA receptors. PMID- 30280378 TI - Complex effects of laminopathy mutations on nuclear structure and function. AB - The nuclear lamins are important members of the intermediate filament (IF) family of proteins, involved in structural support and regulation of the nuclear lamina. Different mutations in various members of these type V IF proteins produce a staggering range of human disease phenotypes, which collectively have been termed "laminopathies." Compelling examples are the wide range of inherited disorders that result from rare variants in LMNA encoding lamin A/C. These laminopathies include skeletal and cardiac muscle disorders, neuropathies, multisystem progeroid disorders, and lipodystrophies, of which the latter are associated with several metabolic complications. Functions of lamin A/C that have been shown to be compromised by distinct mutations in LMNA include loss of nuclear structural integrity, altered interaction with transcription factors, and changes to post translational processing of pre-lamins. Recently, evidence has emerged that certain LMNA mutations, such as those causing partial lipodystrophy, alter the interaction between chromatin and lamin A, in turn affecting the spatial orientation and distribution of chromatin within the nucleus. Because chromatin organization is exquisitely tied to global patterns of gene expression, the findings suggest a novel mechanism to explain the tissue-specific impact of a subset of laminopathy-associated LMNA mutations. PMID- 30280379 TI - Occasional long distance dispersal increases spatial synchrony of population cycles. AB - Spatially separated populations of the same species often exhibit correlated fluctuations in abundance, a phenomenon known as spatial synchrony. Dispersal can generate spatial synchrony. In nature, most individuals disperse short distances with a minority dispersing long distances. The effect of occasional long distance dispersal on synchrony is untested, and theoretical predictions are contradictory. Occasional long distance dispersal might either increase both overall synchrony and the spatial scale of synchrony, or reduce them. We conducted a protist microcosm experiment to test whether occasional long distance dispersal increases or decreases overall synchrony and the spatial scale of synchrony. We assembled replicate 15-patch ring metapopulations of the protist predator Euplotes patella and its protist prey Tetrahymena pyriformis. All metapopulations experienced the same dispersal rate, but differed in dispersal distance. Some metapopulations experienced strictly short distance (nearest neighbour) dispersal, others experienced a mixture of short- and long distance dispersal. Occasional long distance dispersal increased overall spatial synchrony and the spatial scale of synchrony for both prey and predators, though the effects were not statistically significant for predators. As predicted by theory, dispersal generated spatial synchrony by entraining the phases of the predator prey cycles in different patches, a phenomenon known as phase locking. Our results are consistent with theoretical models predicting that occasional long distance dispersal increases spatial synchrony. However, our results also illustrate that the spatial scale of synchrony need not match the spatial scale of the processes generating synchrony. Even strictly short distance dispersal maintained high spatial synchrony for many generations at spatial scales much longer than the dispersal distance, thanks to phase locking. PMID- 30280380 TI - Responses of ant communities to disturbance: Five principles for understanding the disturbance dynamics of a globally dominant faunal group. AB - Ecological disturbance is fundamental to the dynamics of biological communities, yet a conceptual framework for understanding the responses of faunal communities to disturbance remains elusive. Here, I propose five principles for understanding the disturbance dynamics of ants-a globally dominant faunal group that is widely used as bioindicators in land management, which appear to have wide applicability to other taxa. These principles are as follows: (1) The most important effects of habitat disturbance on ants are typically indirect, through its effects on habitat structure, microclimate, resource availability and competitive interactions; (2) habitat openness is a key driver of variation in ant communities; (3) ant species responses to disturbance are to a large degree determined by their responses to habitat openness; (4) the same disturbance will have different effects on ants in different habitats, because of different impacts on habitat openness; and (5) ant community responses to the same disturbance will vary according to ant functional composition and biogeographical history in relation to habitat openness. I illustrate these principles using results primarily from studies of ant responses to fire, a dominant agent of disturbance globally, to provide a common disturbance currency for comparative analysis. I argue that many of the principles also apply to other faunal groups and so can be considered as general ecological "laws." As is the case for ants, many impacts of habitat disturbance on other faunal groups are fundamentally related to habitat openness, the effects of disturbance on it and the functional composition of species in relation to it. PMID- 30280381 TI - Multiple density-dependent processes shape the dynamics of a spatially structured amphibian population. AB - Understanding the mechanisms that regulate the dynamics of spatially structured populations (SSP) is a critical challenge for ecologists and conservation managers. Internal population processes such as births and deaths occur at a local level, while external processes such as dispersal take place at an inter population level. At both levels, density dependence is expected to play a critical role. At a patch scale, demographic traits (e.g., survival, breeding success) and the population growth rate can be influenced by density either negatively (e.g., competition effect) or positively (e.g., Allee effects). At the scale of an SSP, although positive density-dependent dispersal has been widely reported, an increasing number of studies have highlighted negative density dependent dispersal. While many studies have investigated the effects of density on population growth or on dispersal, few have simultaneously examined density dependent effects at the scale of both the local population and the entire SSP. In this study, we examine how density is related to demographic processes at both the pond level (survival and population growth) and the SSP level (between-pond dispersal) in a pond-breeding amphibian, the great crested newt (Triturus cristatus). The study was based on 20 years of individual capture-recapture (CR) data (from 1996 to 2015) gathered from an SSP made up of 12 experimental ponds ("patches"). We first used a CR multievent model to estimate both survival and dispersal rates in specific ponds as a function of distance between ponds. Then, using a second CR multievent model, we examined whether survival and recapture rates were influenced by population density in a pond. Lastly, we used state space time series models to investigate whether density affected population growth in each pond. Our results found a positive density-dependent effect on survival and a negative density-dependent effect on departure. In addition, the findings indicate that population growth was negatively related to density in all 12 ponds. These results support the hypothesis that in SSPs, density may have multiple and contrasting effects on demographic parameters and growth rates within local populations as well as on dispersal. This study underlines the need to better understand how density dependence may influence potential trade-offs between life-history strategies and life-history stages.

AB - Body mass estimation in fossil human species is a crucial topic in paleoanthropology as it yields information about ecologically relevant characteristics. Nevertheless, variables crucial to body mass estimation such as bone volume and skeletal weight have never before been calculated in a fossil human species. The exceptional state of preservation of several fossil human long bones from the Sima de los Huesos (SH) Middle Pleistocene site, in the Sierra de Atapuerca, makes it possible to calculate for the first time the absolute bone volume in five complete long bones (two femora and three humeri) of a fossil human species, an approach not possible in fragmentary or poorly preserved fossils. We have relied on computed tomography scans and 3D reconstructions to calculate bone volume. A sample of 62 complete bones of robust recent humans was also used for comparative purposes. The male SH femora (weight-bearing bones) and humeri (non-weight-bearing bones) have, relative to their size, greater bone volume (volume of bone tissue over total bone volume) than the equivalent bones in our recent human sample. As mass is volume * density, and bone tissue density (as a material) is similar across mammals, we calculate bone mass, and our results show that the SH hominins had on average heavier long bones than extant humans of the same size. From the femoral weight at hand, we have estimated the total skeletal weight in two SH individuals, which is about 36% heavier than in the recent humans of the equivalent body size. Using different methods and skeletal variables, including skeletal weight, to estimate body mass in these two SH humans, we highlight the considerable differences in body mass estimates we obtained, and that the largest body mass estimate is the one based on the skeletal weight. Our results suggest that we cannot assume the same relative proportion of bone volume and bone and skeletal weight characterized the entire genus Homo. Given that skeletal weight has a significant influence on body mass, current body mass estimates of fossil Homo specimens could be systematically underestimated. Thus, the significantly larger bone volume and heavier bones, probably throughout the entire skeleton, of SH humans could have had consequences for many biological parameters in this Pleistocene population and considerable importance for studies focusing on adaptive and ecologically relevant characteristics. Although more recent human samples should be analyzed, in our view, the high skeletal robusticity of the SH sample, including larger bone volume and skeletal weight, is part of their adaptive body type selected for throughout the Pleistocene to support different mechanical and activity regimes and formed under tight genetic control, including control over bone formative and regulatory processes.

AB - Porphyromonas gingivalis is a Gram-negative anaerobic bacterium that has been considered to be one of the bacteria associated with progression of human periodontitis. Subgingival biofilms formed by bacteria, including P. gingivalis, induce chronic inflammation, and activation of inflammasome in the gingival tissue. However, the mechanisms of P. gingivalis-triggering inflammasome activation and the role of bacteria-host interactions are controversial. In this study, we investigated the potential of P. gingivalis for triggering inflammasome activation in human cells and mouse models. We demonstrated that secreted or released factors from bacteria are involved in triggering NLR family, pyrin domain containing 3 protein (NLRP3) inflammasome in a gingipain-independent manner. Our data indicated that released active caspase-1 and mature IL-1beta are eliminated by proteolytic activity of secreted gingipains. These results elucidate the molecular bases for the mechanisms underlying P. gingivalis triggered inflammasome activation. PMID- 30280384 TI - Zebra diel migrations reduce encounter risk with lions at night. AB - Diel migrations (DM; back and forth diel movements along an ecological gradient) undertaken by prey to avoid predators during the day have been demonstrated in many taxa in aquatic ecosystems. In terrestrial ecosystems, prey often shift between various vegetation types whose cover determine their vulnerability (i.e., likelihood of being killed when attacked). We conceptualized that in terrestrial ecosystems, DM could also occur and that the contribution of DM and shifts in vegetation cover use in reducing predation risk should depend upon the predator behaviour and the correlation between encounter risk and vulnerability across vegetation types. We further hypothesized that when the predator distribution is predictable, terrestrial prey could have evolved DM strategies taking them away from the predator when it is active or efficient. We investigated whether plains zebras Equus quagga perform DM in Hwange National Park (Zimbabwe). There, zebras can forage in large patches of open grasslands located near waterholes where they can also easily detect predators. However, they are there at high risk of encountering their main predator, lions Panthera leo, especially at night. We found out that zebras employ a DM anti-predator strategy. Zebras forage near waterholes during the day but move away from them at sunset, when lions become active. We demonstrated that this DM, occurring over a few kilometres, dramatically reduces their night-time risk of encountering lions, which generally remain close to waterholes. Zebra changes in night-time selection for vegetation cover types reduced their risk of encountering lions much less. This may arise from a trade-off between encounter risk and vulnerability across vegetation types, with zebras favouring low vulnerability once DM has reduced encounter risk. In summary, here we (a) quantify, in a terrestrial system, the effect of a predator-induced DM on the likelihood of encountering a predator and (b) distinguish the effects of the DM on encounter risk from those related to day/night changes in selection for vegetation types. We discuss how prey partition their risk between encounter risk and habitat-driven vulnerability and why it is likely critical to understand the emergence of anti-predator behavioural strategies. PMID- 30280386 TI - Urbanization-driven changes in web building and body size in an orb web spider. AB - In animals, behavioural responses may play an important role in determining population persistence in the face of environmental changes. Body size is a key trait central to many life-history traits and behaviours. Correlations with body size may constrain behavioural variation in response to environmental changes, especially when size itself is influenced by environmental conditions. Urbanization is an important human-induced rapid environmental change that imposes multiple selection pressures on both body size and (size-constrained) behaviour. How these combine to shape behavioural responses of urban-dwelling species is unclear. Using web building, an easily quantifiable behaviour linked to body size and the garden spider Araneus diadematus as a model, we evaluated direct behavioural responses to urbanization and body size constraints across a network of 63 selected populations differing in urbanization intensity. We additionally studied urbanization at two spatial scales to account for some environmental pressures varying across scales and to obtain first qualitative insights about the role of plasticity and genetic selection. Spiders were smaller in highly urbanized sites (local scale only), in line with expectations based on reduced prey biomass availability and the Urban Heat Island effect. Web surface and mesh width decreased with urbanization at the local scale, while web surface also increased with urbanization at the landscape scale. The latter two responses are expected to compensate, at least in part, for reduced prey biomass availability in cities. The use of multivariate mixed modelling reveals that although web traits and body size are correlated within populations, behavioural responses to urbanization do not appear to be constrained by size: there is no evidence of size-web correlations among populations or among landscapes, and web traits appear independent from each other. Our results demonstrate that responses in size-dependent behaviours may be decoupled from size changes, thereby allowing fitness maximization in novel environments. The spatial scale at which traits respond suggests contributions of both genetic adaptation (for web investment) and plasticity (for mesh width). Although fecundity decreased with local-scale urbanization, A. diadematus abundances were similar across urbanization gradients; behavioural responses thus appear overall successful at the population level. PMID- 30280387 TI - Explaining the variability in the response of annual eusocial insects to mass flowering events. AB - Empirical studies of annual eusocial insects in agricultural landscapes report contrasting findings with regard to colony responses to mass-flowering of crops such as oilseed rape. In particular, total sexual production is often unaffected by such events, whereas worker number responds with a prominent increase. To resolve these conflicting observations, we model-using an established approach the expected change in worker and sexual numbers in response to an increased worker productivity induced by mass-flowering events at different times of the season. We find that the predicted response pattern is mainly shaped by the degree to which individual worker productivity is reduced by an increasing number of workers in the colony. Different environmental conditions and colony characteristics result in different levels of interference of workers, for example, during foraging or nest construction. Reduction in individual productivity is low, when worker interference is negligible ("weak limitation") and high when an increasing number of workers substantially decreases per-capita efficiency ("strong limitation"). For weak limitation, any mass-flowering event that ends before the production of sexuals starts has a strong multiplicative impact on both worker and sexual numbers. The magnitude of the effect is quite independent of the precise timing of such an event. After the onset of sexual production, mass-flowering has a weaker effect, as the added resource supply is only linearly transferred into production of additional sexuals. For colonies under strong limitation, the predicted impact of mass-flowering events is generally weaker, especially on the production of sexuals, and the timing of mass flowering events becomes more influential: Production of sexuals profits more from late than from early mass-flowering events. Consequently, early mass flowering events are predicted to have a prominent effect on worker numbers but a negligible one on the output of sexuals. The model presented provides a mechanistic explanation of why increased worker abundances do not necessarily translate into increased production of sexuals. The model is also applicable to other eusocial insects such as paper wasps whenever brief pulses of massive resource availability shortly elevate resource intake rates above the "normal" levels. PMID- 30280388 TI - The hypolipidemic effects of Tamarindus indica fruit pulp extract in normal and diet-induced hypercholesterolemic hamsters are associated with altered levels of serum proteins. AB - The hypolipidemic effects of Tamarindus indica fruit pulp extract (Ti-FPE) have been earlier reported but the underlying molecular mechanisms are still uncertain. In this study, hamsters fed with Ti-FPE, both in the absence and presence of high-cholesterol diet, were shown to have significantly reduced levels of serum triglyceride, LDL-C and total cholesterol. The Ti-FPE-fed non hypercholesterolemic hamsters also showed significant enhanced levels of serum apolipoprotein A1, antithrombin III, transferrin and vitamin D binding protein. In diet-induced hypercholesterolemic hamsters, apolipoprotein A1, antithrombin III and transferrin, which were relatively low in levels, became significantly enhanced when the hamsters were fed with Ti-FPE. These Ti-FPE-fed hypercholesterolemic hamsters also showed significant higher levels of serum vitamin D binding protein. When the different treated groups of hamsters were analyzed for the levels of the four serum proteins by ELISA, similar altered abundance were detected. Ingenuity Pathway Analysis of the Ti-FPE modulated serum proteins singled out "Lipid metabolism, molecular transport, small molecule biochemistry" as the top network. Our results suggest that the hypolipidemic effects of Ti-FPE are associated with alterations of serum proteins that are known to be cardioprotective and involved in the metabolism of lipids. The MS data have been deposited to the ProteomeXchange Consortium with the dataset identifier PXD010232. PMID- 30280389 TI - Separation-free single-base extension assay with fluorescence resonance energy transfer for rapid and convenient determination of DNA methylation status at specific cytosine and guanine dinucleotide sites. AB - A separation-free single-base extension (SBE) assay utilizing fluorescence resonance energy transfer (FRET) was developed for rapid and convenient interrogation of DNA methylation status at specific cytosine and guanine dinucleotide sites. In this assay, the SBE was performed in a tube using an allele-specific oligonucleotide primer (i.e., extension primer) labeled with Cy3 as a FRET donor fluorophore at the 5'-end, a nucleotide terminator (dideoxynucleotide triphosphate) labeled with Cy5 as a FRET acceptor, a PCR amplicon derived from bisulfite-converted genomic DNA, and a DNA polymerase. A single base-extended primer (i.e., SBE product) that was 5'-Cy3- and 3'-Cy5 tagged was formed by incorporation of the Cy5-labeled terminator into the 3'-end of the extension primer, but only if the terminator added was complementary to the target nucleotide. The resulting SBE product brought the Cy3 donor and the Cy5 acceptor into close proximity. Illumination of the Cy3 donor resulted in successful FRET and excitation of the Cy5 acceptor, generating fluorescence emission from the acceptor. The capacity of the developed assay to discriminate as low as 10% methylation from a mixture of methylated and unmethylated DNA was demonstrated at multiple cytosine and guanine dinucleotide sites. PMID- 30280390 TI - First-time-in-human randomized clinical trial in healthy volunteers and haemodialysis patients with SNF472, a novel inhibitor of vascular calcification. AB - AIMS: SNF472 is a calcification inhibitor being developed for the treatment of cardiovascular calcification in haemodialysis (HD) and in calciphylaxis patients. This study investigated the safety, tolerability and pharmacokinetics (PK) of intravenous (IV) SNF472 in healthy volunteers (HV) and HD patients. METHODS: This is a first-time-in-human, double-blind, randomized, placebo-controlled Phase I study to assess the safety, tolerability and PK of SNF472 after ascending single IV doses in HV and a single IV dose in HD patients. A pharmacodynamic analysis was performed to assess the capability of IV SNF472 to inhibit hydroxyapatite formation. RESULTS: Twenty HV and eight HD patients were enrolled. The starting dose in HV was 0.5 mg kg-1 and the dose ascended to 12.5 mg kg-1 . The dose selected for HD patients was 9 mg kg-1 . Safety analyses support the safety and tolerability of IV SNF472 in HD patients and HV. Most treatment-emergent adverse events were mild in intensity. No clinically significant effects were observed on vital signs or laboratory tests. PK results were similar in HD patients and HV and indicate a lack of significant dialysability. Pharmacodynamic analyses demonstrated that SNF472 administration reduced hydroxyapatite crystallization potential in HD patients who received IV SNF472 9 mg kg-1 by 80.0 +/- 2.4% (mean +/- standard error of the mean, 95% CI, 75.3-84.8) compared to placebo (8.7 +/- 21.0%, P < 0.001, 95% CI, -32.4 to 49.7). CONCLUSION: The results from this study showed acceptable safety and tolerability, and lack of significant dialysability of IV SNF472. It is a potential novel treatment for cardiovascular calcification in end-stage renal disease and calciphylaxis warranting further human studies. PMID- 30280391 TI - Monitoring Early Breast Cancer Response to Neoadjuvant Therapy Using H-Scan Ultrasound Imaging: Preliminary Preclinical Results. AB - OBJECTIVE: H-scan imaging is a new ultrasound technique used to visualize the relative size of acoustic scatterers. The purpose of this study was to evaluate the use of H-scan ultrasound imaging for monitoring early tumor response to neoadjuvant treatment using a preclinical breast cancer animal model. METHODS: Real-time H-scan ultrasound imaging was implemented on a programmable ultrasound scanner (Vantage 256; Verasonics Inc., Kirkland, WA) equipped with an L11-4v transducer. Bioluminescence and H-scan ultrasound was used to image luciferase positive breast cancer-bearing mice at baseline and at 24, 48, and 168 hours after administration of a single dose of neoadjuvant (paclitaxel) or sham treatment. Animals were euthanized at 48 or 168 hours, and tumors underwent histologic processing to identify cancer cell proliferation and apoptosis. RESULTS: Baseline H-scan ultrasound images of control and therapy group tumors were comparable, but the latter exhibited significant changes over the 7-day study (P < .05). At termination, there was a marked difference between the H-scan ultrasound images of control and treated tumors (P < .05). Specifically, H-scan ultrasound images of treated tumors were more blue in hue than images obtained from control tumors. There was a significant linear correlation between the predominance of the blue hue found in the H-scan ultrasound images and intratumoral apoptotic activity (R2 > 0.40, P < .04). CONCLUSION: Preliminary preclinical results suggest that H-scan ultrasound imaging is a new and promising tissue characterization modality. H-scan ultrasound imaging may provide prognostic value when monitoring early tumor response to neoadjuvant treatment. PMID- 30280393 TI - Factors associated with false-negative pathologic diagnosis of calciphylaxis. AB - BACKGROUND: Calciphylaxis is a rare, painful, and debilitating disorder of vascular calcification and skin necrosis that typically affects patients with advanced kidney disease. During our routine pathology practice, we noted several missed diagnoses on calciphylaxis consultation cases originating from outside institutions and sought to explore factors associated with false-negative pathologic diagnosis of calciphylaxis. METHODS: The pathology database of a large tertiary academic medical center was retrospectively searched for "calciphylaxis" in inside reports on outside surgical consultation cases between 2007 and 2017. Inside and outside pathology reports were compared and medical records were searched for calciphylaxis clinical diagnosis and risk factors. RESULTS: Twenty four calciphylaxis patients were identified, with median age of 63.5 years. Seven of 24 (29%) of specimens were inadequate (e.g., lack of subcutaneous adipose tissue for evaluation). Eight of 17 (47%) of adequate specimens had a first false negative pathologic diagnosis of calciphylaxis. Histochemical staining for calcium significantly correlated with true-positive diagnosis (93% vs 55%, P = 0.004). Dermatopathology fellowship training significantly correlated with true positive diagnosis (82% vs 38%, P = 0.047). CONCLUSIONS: Adequate sampling, dermatopathology training, and use of histochemical stains to identify calcium associate with decreased false-negative rate for calciphylaxis diagnosis. These findings need further evaluation in larger prospective studies. PMID- 30280392 TI - Response to 'Comment on ''Massive' metformin overdose' by Chiew et al.'

PMID- 30280395 TI - Establishment of normative values for the fetal posterior fossa by magnetic resonance imaging. AB - OBJECTIVE: Suspected Dandy-Walker continuum anomalies constitute a significant percentage of prenatal cases evaluated by magnetic resonance imaging (MRI). To unify the description of posterior fossa malformations, we sought to establish objective measurements for the posterior fossa in normal fetuses between 18 and 37 weeks gestation. METHODS: T2-weighted images of normal fetal brains in sagittal projection were obtained from fetal magnetic resonance (MR) studies of normal brains performed from 2009 to 2017.121 fetal brains were included in the analysis. Three radiologists reviewed images and recorded the following for each case: superior posterior fossa angle (SPFA), posterior fossa perimeter, and tegmento-vermian angle (TVA). RESULTS: For each feature, the mean of the measurements, the percentage of absolute difference of the reader measurement compared with mean measurement, and the interclass correlation (ICC) were calculated. Values are reported as mean +/- standard deviation. Perimeter increases linearly with age, whereas the SPFA and the TVA are independent of gestational age. For all included cases, the SPFA averaged 100.9 degrees +/- 8 degrees and the TVA averaged 2.5 degrees +/- 2.3 degrees . CONCLUSION: The superior posterior fossa angle, a novel measurement, and the posterior fossa perimeter can be used for establishing the expected size of the posterior fossa in second- and third-trimester fetuses by MRI. PMID- 30280396 TI - The Use of Transesophageal Echocardiography During Cardiac Arrest Resuscitation: A Literature Review. AB - We propose that transesophageal echocardiography (TEE) can be used to guide cardiac arrest resuscitation. We undertook a literature search (Medline and EMBase) to assess articles on that topic. Our search yielded 55 articles falling into 3 categories: TEE used in operating rooms, TEE used in emergency departments, and TEE used in other settings. In many cases, TEE changed the direction of the resuscitation; however, it is unclear whether TEE changed patient-oriented outcomes, such as neurologically intact survival. Few adverse events related to TEE have been documented. There is growing evidence that physicians can learn to use TEE during resuscitations and apply the findings to clinical decisions. PMID- 30280397 TI - Wrist Flexion Exercise Increases the Width of the Medial Elbow Joint Space During a Valgus Stress Test. AB - OBJECTIVES: The medial elbow is stabilized during valgus loading by the ulnar collateral ligament, the flexor pronator mass (FPM), and the radial head. Impairment of the FPM can occur as a result of repeated wrist flexion activity. The purpose of this study was to determine the effect of repeated elbow flexion exercise on medial elbow stability. METHODS: Thirty volunteers were included in this study. Ultrasound images of the medial joint space of the nondominant elbow of the participants were collected during a valgus stress test. The images were collected before and immediately after a wrist flexion exercise protocol. RESULTS: The wrist flexion strength measure decreased (7.5%) after the exercise protocol (t = 3.840; P = .001). The medial elbow width increased between unstressed (mean +/- SD, 2.8 +/- 0.1 mm) and stressed (3.6 +/- 0.1 mm) conditions (P < .001). The stress-by-fatigue interaction was significant (P = .048). The medial elbow width increased after fatigue (0.9 +/- 0.09 mm) while remaining unchanged in the unstressed condition. CONCLUSIONS: This study found an effect of repeated wrist flexion exercise on decreasing the stability of the medial elbow. Future research needs to explore the mechanisms leading to the decrease in medial elbow stability and to identify the effect of FPM fatigue on the development of medial elbow pain associated with activities. PMID- 30280399 TI - Percutaneous Ultrasonic Tenotomy Reduces Insertional Achilles Tendinopathy Pain With High Patient Satisfaction and a Low Complication Rate. AB - Due to the novelty of percutaneous ultrasonic tenotomy, the risks and benefits of this minimally invasive procedure for insertional Achilles tendinopathy pain have only been examined in case studies and retrospective chart reviews for other diagnoses. This retrospective chart review over a 3.5-year period identified 34 patients with insertional Achilles tendinopathy who had percutaneous ultrasonic tenotomy (mean age +/- SD, 52.2 +/- 11.6 years; mean body mass index, 32.9 +/- 7.5 kg/m2 ; 62% female). This procedure reduced the rate of moderate/severe pain from 68% at baseline to 15% at the long-term follow-up and had a satisfaction rate of 70%. There was 1 minor complication out of 40 procedures in 34 patients. PMID- 30280398 TI - Comparison of free-energy methods using a tripeptide-water model system. AB - We investigate the ability of several free-energy calculation methods to combine two alchemical changes. We use Bennett acceptance ratio (BAR), thermodynamic integration (TI), extended TI (X-TI), and enveloping distribution sampling (EDS) to perturb a water molecule, which is restrained to an amino acid that is also being perturbed. In addition to these pairwise methods, we present two two dimensional approaches, EDS-TI and two-dimensional TI (2D-TI). We compare feasibility, efficiency and usability of these methods in regard to our simple model system, which mimics the displacement of a water molecule in the active site of a protein on residue mutation. The correct treatment of structural water has been shown to greatly aid binding affinity calculations in some cases that remained elusive otherwise. This is of broad interest in, for example, drug design, and we conclude that thus far, the pairwise method BAR and also the newer X-TI remain the most suitable methods to treat this problem as long as few end states are involved.

AB - OBJECTIVE: This study aims to evaluate the Achilles tendon's properties after rehabilitation training in patients with stroke using real-time ultrasound elastography. METHODS: A total of 24 patients with mild hemiplegic stroke in the past 6 to 12 months and unilateral lower limb movement disorder were prospectively enrolled. All patients accepted 9-week rehabilitation training with the same schema. The 2-dimensional elastography and real-time elastography findings in the impaired and contralateral normal Achilles tendon were measured at pretraining and at 3, 6, and 9 weeks after training, which included tendon length, thickness, elasticity score (grade 1-3), and strain ratio of fat to tendon. The functional properties, which include the 10-meter walk test and timed up-and-go scores, were evaluated before and after the 9-week training. RESULTS: The impaired Achilles tendon had a longer length (P = .002), lower frequency of grade 1 (P = .012), and lower strain ratio (P = .009) than the contralateral tendon before training. The impaired tendons at the third, sixth, and ninth weeks after training were compared to ones before training, respectively, which revealed shorter length, increased frequency of grade 1, and increased strain ratio. The first statistically significant changes in the length were observed at the sixth week, while such changes in elasticity score and strain ratio were observed at the ninth week. CONCLUSIONS: Two-dimensional elastography and real time elastography can provide valuable imaging markers for quantitatively evaluating the Achilles tendon's properties after rehabilitation training in patients with stroke. PMID- 30280401 TI - Bedside Ultrasound Versus Chest Radiography for Detection of Pulmonary Edema: A Prospective Cohort Study. AB - OBJECTIVES: Chest radiography has been the preferred imaging study to assess pulmonary congestion. However, chest radiography interpretation is influenced by the level of expertise and high interobserver variability. Lung ultrasound (US) may produce more objective findings through evaluation of vertical comet tail artifacts known as B-lines, which are created by a decrease in the ratio of alveolar air to fluid pulmonary content. Few studies have directly compared chest radiography to bedside US against a reference standard for the diagnosis of pulmonary edema. This study compared the sensitivity and specificity of bedside US and chest radiography in diagnosing pulmonary edema. METHODS: This prospective observational cohort study involved adult patients presenting to the emergency department of an urban tertiary hospital with dyspnea. The primary outcome was the presence or absence of pulmonary edema, as indicated by B-lines on a bedside lung US examination or radiologist-interpreted chest radiography. Patients underwent a US examination within about 1 hour of chest radiography. The final diagnosis from the discharge summary served as the reference standard. RESULTS: Ninety-nine patients were enrolled; 32.3% had congestive heart failure, and 40.4% had chronic obstructive pulmonary disease. Bedside US showed significantly higher sensitivity (96%) compared to chest radiography (65%; P < .001). Of 18 patients with negative radiographic findings and a discharge diagnosis of pulmonary edema, 16 (89%) had positive US findings (P < .001). CONCLUSIONS: Bedside US has the potential to identify pulmonary edema more accurately than chest radiography. As current practice within the United States uses chest radiography, reflecting American College of Cardiology Foundation/American Heart Association guidelines for management of heart failure, the results of this study warrant further evaluation. PMID- 30280402 TI - Prenatal Evaluation for Detection of Anorectal Atresia: Value of Ultrasound. AB - OBJECTIVES: To investigate the applicability and value of ultrasound (US) in the diagnosis of anorectal atresia. METHODS: Between January 2008 and January 2016, we prospectively evaluated 63,101 fetuses (gestational age, 20-38 weeks), including low- and high-risk populations using 2-dimensional US scans. An abnormal imaging finding was defined as an anal canal diameter of less than the 95% confidence interval (small anal canal) of the normal range or the absence of an anal canal and rectum. Imaging findings were considered normal on detection of an anal canal with a normal width and the absence of abnormalities. Prenatal imaging findings were confirmed by a postnatal or postmortem examination. RESULTS: Among the investigated fetuses, 28 showed evidence of anorectal atresia on US scans, and 22 of those with anorectal atresia had additional anomalies. Six cases of isolated anorectal atresia were successfully detected during the preclusive prenatal US scans. Four cases of a low imperforate anus (including 2 covered anuses) yielded false-negative results, indicating a diagnostic rate of 87.5% (28 of 32). The normal appearance of the fetal rectum and anal canal ruled out anorectal atresia in 30 fetuses with a dilated colon. Additionally, there were 3 false-positive cases, in which a narrow anal canal was observed. CONCLUSIONS: Identifying the abnormal appearance or absence of the fetal anal canal and rectum on preclusive US anomaly scans is useful for prenatal diagnosis or exclusion of anorectal atresia, which may help improve the detection of isolated anorectal atresia. Furthermore, a combined evaluation of the longitudinal and axial appearances of the fetal anal canal and rectum can improve diagnostic accuracy. PMID- 30280403 TI - Diving into chemical bonding: An immersive analysis of the electron charge rearrangement through virtual reality. AB - An integrated environment for the analysis of chemical bonding based on immersive virtual reality is presented. Using a multiscreen stereoscopic projection system, researchers are cast into the world of atoms and molecules, where they can visualize at a human scale the electron charge rearrangement (computed via state of-the-art quantum-chemical methods) occurring on bond formation throughout the molecular region. Thanks to specifically designed features, such a virtual laboratory couples the immediacy of an immersive experience with a powerful, recently developed method yielding quantitative, spatially detailed pictures of the several charge flows involved in the formation of a chemical bond. By means of two case studies on organometallic complexes, we show how familiar concepts in coordination chemistry, such as donation and back-donation charge flows, can be effectively identified and quantified to predict experimental observables.

AB - INTRODUCTION: This study was conducted to evaluate the 24-segment transverse widths of the right and left ventricles distributed from the base to the apex of the ventricular chambers and compute the right ventricular (RV)/left ventricular (LV) ratios for each segment. METHODS: Two hundred control fetuses were examined between 20 and 40 weeks' gestation. Using offline speckle-tracking software, the 24 end-diastolic transverse widths were computed and the RV/LV ratios were regressed against 7 independent variables related to the size, weight, and age of the fetuses. Five fetuses with coarctation of the aorta and 5 fetuses with pulmonary stenosis were examined to exemplify the utility of these measurements. FINDINGS: The 24-segment transverse widths were associated with changes in fetal size, weight, and age. Regression equations were developed to describe these changes with R2 values between .5 and .82. The measurements were normally distributed (Shapiro-Wilk > 0.5). The RV/LV ratio for the 24 segments did not strongly correlate (R2 = .001 to -.2) with fetal size, weight, or gestational age. Fetuses with coarctation of the aorta and pulmonary stenosis demonstrated characteristic changes in the 24-segment transverse widths and the RV/LV ratios in the basal (segments 1-8), mid (segments 9-16) and apical (segments 17-24) sections of the ventricles. CONCLUSIONS: The 24-segment transverse widths of the right and left ventricles and the RV/LV ratios provide a comprehensive method to examine the width of the ventricular chambers.

AB - OBJECTIVES: The hemodynamics of the ultrasound (US) features of port-wine stains (PWSs) have not been reported. The purpose of this study was to evaluate the high frequency US findings of PWSs. METHODS: We retrospectively reviewed 98 PWS cases and categorized them into 4 groups based on clinical manifestations and pathologic findings (14 nodular, 28 thickened, 52 flattened, and 4 acquired). We evaluated the US findings with 10- and 22-MHz transducers. RESULTS: For nodular PWSs, the mean thickened skin +/- SD was 0.6 +/- 0.5 mm, and the nodule thickness was 5.7 +/- 3.3 mm; 63.6% of skin lesions showed vessel density of 2.16 +/- 0.93/cm2 with venous flow of 4.6 +/- 1.1 cm/s, and all nodules showed vessel density of 6.14 +/- 1.92/cm2 with arterial and venous flow of 26.6 +/- 17.9 and 9.9 +/- 5.1 cm/s, respectively. The thickened skin of the thickened type was 1.4 +/- 2.7 mm; 76.5% of skin lesions showed vessel density of 3.81 +/- 1.98/cm2 with venous flow 4.6 +/- 2.1 cm/s. The thickened skin of 36 flattened lesions was 0.1 +/- 0.1 mm; 91.7% of skin lesions showed vessel density of 1.08 +/- 0.28/cm2 . The thickened skin of 4 acquired lesions was 0.7 +/- 0.4 mm; 50% showed vessel density of 1.08 +/- 0.28/cm2 . The thickened skin and vessel density of nodular and thickened PWSs were thicker and higher than those of the flattened ones. The 22-MHz transducer produced clearer contrast and higher vessel density than the 10 MHz transducer. CONCLUSIONS: These results showed differences in US findings of PWSs, which may be useful for clinical diagnosis. PMID- 30280406 TI - Keratosis pilaris rubra with mucin deposition. AB - Keratosis pilaris (KP) is a benign cutaneous disorder characterized by folliculocentric hyperkeratotic papules most often occurring on the proximal extremities. Erythema is usually limited to perifollicular skin, but when keratosis pilaris presents on a background of confluent erythema, the term keratosis pilaris rubra (KPR) is used. The histological findings associated with KP have not been well described in the literature. Herein, we present a case of a 14-year-old male with a 7-year history of erythema and follicular-based papules over his bilateral cheeks, consistent with KPR. Histological examination revealed abundant mucin, keratotic follicular plugging, and periadnexal lymphocytosis. Our novel finding of abundant dermal mucin expands the histopathologic description of KPR.

AB - BACKGROUND: Prostate cancer (PCa) is diagnosed at the highest rate of all non cutaneous male cancers in the United States. The androgen-dependent (AD) transcription factor, androgen receptor (AR), drives PCa-but inhibiting AR or androgen biosynthesis induces remission for only a short time. At which point, patients acquire more aggressive castration-resistant (CR) disease with re activated AR-dependent signaling. To combat treatment resistance, down-regulating AR protein expression has been considered as a potential treatment strategy for CR-PCa. METHODS: AD- and CR-PCa cell lines were treated with the well-tolerated FDA-approved oral medicine, riluzole. Expression of full-length or wild-type AR (AR-FL) and constitutively active AR-splice variant 7 (AR-V7) was assessed by immunoblotting. AR-FL/AR-V7 activity was measured using qRT-PCR of AR-target genes. Cytoplasmic [Ca2+ ] levels were measured using a fluorescent Ca2+ indicator microplate assay. Markers of the endoplasmic reticulum stress (ERS) pathway and autophagy were assessed by immunoblotting. Direct interaction between AR and selective autophagy receptor p62 was demonstrated by co immunoprecipitation. RESULTS: We demonstrate that riluzole downregulates AR-FL, mutant ARs, and AR-V7 proteins expression by protein degradation through ERS pathway and selective autophagy. Riluzole also significantly inhibited AR transcription activity by decreasing its target genes expression (PSA, TMPRSS2, and KLK2). CONCLUSIONS: We provide key mechanistic insights by which riluzole exerts its anti-tumorigenic effects and induces AR protein degradation via ERS pathways. Our findings support the potential utility of riluzole for treatment of PCa. PMID- 30280408 TI - Acitretin as a successful treatment for Hailey-Hailey disease.

AB - The inner ear can be the target of autoimmune attacks, and sensorineural hearing loss can occur as a complication in various non-organ-specific autoimmune diseases. The aim of this study was to compare cochlear functions and hearing evaluation in patients with psoriasis and controls. In total, 29 patients with psoriasis and 30 healthy controls (HCs) were included in the study. Pure-tone audiometry at 250, 500, 1000, 2000, 4000, 8000, 10 000, 12 000, 14 000 and 16 000 Hz was performed for patients as HCs, as were immittance measures including tympanometry, acoustic reflex and otoacoustic emission testing. There were statistically significant (P < 0.05) differences between patients and HCs for pure-tone thresholds at high frequencies, and for distortion product otoacoustic emission (DPOAE) responses and signal : noise ratio at all frequencies. In our study, based on DPOAE and audiological findings, there was damage to the outer hair cells of the cochlea, resulting in high-frequency hearing loss in patients with psoriasis. PMID- 30280412 TI - Sporadic pemphigus foliaceus and class II human leucocyte antigen allele associations in the white British and Indo-Asian populations in the UK. AB - BACKGROUND: Pemphigus foliaceus (PF) has both genetic and environmental susceptibility factors. Current data on human leucocyte antigen (HLA) in patients with sporadic PF are limited. AIM: To better define the distribution of HLA alleles in patients with PF in the UK. METHODS: We recruited 36 patients [26 of white British (WB) descent, 10 of Indo-Asian (IA) descent] with PF who were living in the UK and 159 ethnically matched normal controls, and analysed their class II HLA DRB1 and DQB1 allele distribution. RESULTS: There was an increased frequency of DRB1*1404 in association with DQB1*0503 in IA patients with PF. The DRB1*04 allele group as a whole had an increased frequency (P < 0.001) in the WB patient group compared with controls. The alleles contributing to this significance were DRB1*0401 (P = 0.03) and DRB1*0404 (P < 0.01). CONCLUSION: This is the largest HLA association study in sporadic PF from the UK to date. There appears to be a difference in PF susceptibility alleles between WB and IA patients, highlighting the importance of racial variation in genetic susceptibility to disease development.

AB - Many workers in several different occupations can be exposed to ultraviolet radiation (UVR), which may increase their risk of developing skin cancer. Welding, an occupation employing an estimated 11 million people worldwide, is one such occupation. Welders are known to be exposed to the full spectrum of UVR from the welding arc and often experience burns and localized cutaneous erythema. In 2017, UVR from welding was classified as carcinogenic to humans based on sufficient evidence of ocular melanoma in humans. It has been hypothesized that exposure to UVR from the welding arc also may increase the risk of skin cancer among workers in this occupation. This review summarizes the current literature on skin cancer risk in welders. PMID- 30280418 TI - Dental implants-associated release of titanium particles: A systematic review. AB - OBJECTIVES: The presence of titanium (Ti) particles around dental implants has been reported in the literature for decades. The prospective presence of Ti debris on soft tissues surrounding dental implants has not been systematically investigated and remains to be explored. Hence, this review aimed to evaluate the origin, presence, characteristics, and location of Ti particles in relation to dental implants. MATERIAL AND METHODS: Literature searches were conducted by two reviewers independently based on the PRISMA guidelines. The systematic review identified studies on Ti particles derived from dental implants. We evaluated several parameters, including anatomical location, and the suspected methods of Ti particles release. RESULTS: The search resulted in 141 articles, of which 26 were eligible and included in the systematic review of the literature. The investigations reported Ti and metal-like particles in the soft (i.e., epithelial cells, connective tissue, and inflammatory cells) and hard (bone crest and bone marrow) tissues around the dental implants. Shape and size of the particles varied. The current literature reported a size range from 100 nm to 54 um identified by multiple particles identification methods. CONCLUSION: Ti particles surrounding peri-implant tissues are a common finding. Peri-implantitis sites presented a higher number of particles compared to healthy implants. The particles were mostly around the implants and inside epithelial cells, connective tissue, macrophages, and bone. Various mechanisms were described as causes of Ti release, including friction during implant insertion, corrosion of the implant surface, friction at the implant-abutment interface, implantoplasty, and several methods used for implant surface detoxification.

PMID- 30280421 TI - Cutaneous hyperpigmentation and familial gastrointestinal stromal tumour associated with KIT mutation. AB - Gastrointestinal stromal tumours (GISTs) are mesenchymal tumours arising in the gastrointestinal tract. Early detection, before metastasis occurs, is important as complete surgical excision achieves cure. Approximately 85% of GISTs are associated with mutations in the KIT gene, and although the majority of GISTs are sporadic, familial GISTs have been identified. Several families with multiple GIST tumours have also been described with various cutaneous findings including hyperpigmentation, multiple lentigines, vitiligo and urticaria pigmentosa. We discuss a 6-year-old boy who presented with an unusual pattern of hyperpigmentation in association with a family history of GIST. A causative KIT mutation was identified in DNA from the pigmented skin and from the resected GIST, and the patient was referred to the Paediatric Gastroenterology department for GIST screening. The term 'GIST cutaneous hyperpigmentation disease' has been suggested previously for the association of familial GIST with cutaneous hyperpigmentation caused by a germline KIT mutation.

AB - There is abundant evidence that the pathophysiology of Parkinson's disease (PD) is not confined to the nigrostriatal dopaminergic pathway but propagates along the cortico-basal ganglia-thalamo-cortical neural network. A critical node in this functional circuit impacted by PD is the primary motor cortex (M1), which plays a key role in generating neural impulses that regulate movements. The past several decades have lay witness to numerous in vivo neuroimaging techniques that provide a window into the function and structure of M1. A consistent observation from numerous studies is that during voluntary movement, but also at rest, the functional activity of M1 is altered in PD relative to healthy individuals, and it relates to many of the motor signs. Although this abnormal functional activity can be partially restored with acute dopaminergic medication, it continues to deteriorate with disease progression and may predate structural degeneration of M1. The current review discusses the evidence that M1 is fundamental to the pathophysiology of PD, as measured by neuroimaging techniques such as positron emission tomography, single-photon emission computed tomography, electroencephalography, magnetoencephalography, and functional and structural MRI. Although novel treatments that target the cortex will not cure PD, they could significantly slow down and alter the progressive course of the disease and thus improve clinical care for this degenerative disease.

PMID- 30280423 TI - Differential expression of interferon-induced genes and other tissue-based biomarkers in acute graft-versus-host disease vs. lupus erythematosus in skin. AB - BACKGROUND: In both acute graft-versus-host disease (GVHD) and lupus erythematosus (LE), the patient's own tissues are subjected to immunological assault via complex mechanisms influenced by interferon (IFN) and other cytokines. Although not typically confused clinically, these entities have overlapping histopathological findings in the skin. AIM: To assess whether GVHD can be differentiated from LE using molecular methods on skin specimens. METHODS: We developed a quantitative reverse transcription PCR assay based on previously identified tissue-based biomarkers of cutaneous GVHD, and compared gene expression in GVHD with that in LE. RESULTS: Both entities showed robust expression of IFN-induced genes and of genes encoding proteins involved in antigen presentation, cell signalling and tissue repair. Levels of gene expression differed significantly in GVHD compared with LE, particularly those of IFN-induced genes such as MX1, OAS3, TAP1 and STAT3 (P < 0.01). Three logistic regression models could differentiate the two entities with a high degree of certainty (receiver operating characteristic area under the curve of 1.0). CONCLUSION: The study demonstrates the feasibility of distinguishing between microscopically similar inflammatory dermatoses using tissue-based molecular techniques.

AB - Bisphosphonate use has been associated with atypical femoral fractures (AFFs), defined by the American Society of Bone and Mineral Research (ASBMR) Task Force criteria, which currently exclude periprosthetic fractures. The objectives of this study were to establish the prevalence of atypical periprosthetic femoral fractures (APFFs) in patients with hip and knee arthroplasties and to determine the clinical and radiological risk factors associated with these fractures. We performed a retrospective radiological review of all femoral fractures between January 1, 2006, and March 31, 2015, in Quebec City, Canada. Patients who sustained a periprosthetic femoral fracture (PFF) were identified and included in this study. We used the ASBMR Task Force criteria to identify atypical fractures and establish their prevalence. Data from medical records and radiological assessments of the femoral anatomy, the characteristics of the fracture, and the positioning of the prosthesis were collected. The prevalence of APFFs among PFFs was 8.3% (11/133). A strong association with bisphosphonates (p = 0.007) was observed, as well as an increased risk of APFFs among alendronate users compared to risedronate users (p = 0.04). A transverse fracture (p < 0.0001), a periosteal thickening of the lateral cortex at the fracture (p < 0.0001), a unicortical fracture (p = 0.02), and prodromal symptoms (p = 0.03) were associated with APFFs. The type of implant, its positioning, and the femoral geometry did not appear to be risk factors for APFFs compared to PFFs. (c) 2018 American Society for Bone and Mineral Research.

AB - BACKGROUND: Vemurafenib has been linked to dermatological adverse events in patients with melanoma, including an increased risk of rash, cutaneous squamous cell carcinoma, photosensitivity reaction and keratoacanthoma. However, there has been no systematic attempt to assess the dermatological toxicity data of vemurafenib associated with melanoma treatment. AIM: To evaluate the point prevalence of dermatological toxicities associated with vemurafenib treatment in patients with melanoma. METHODS: Searches were conducted of the electronic databases PubMed and EMBASE and of conference abstracts published by the American Society of Clinical Oncology. Eligible studies included prospective clinical trials and expanded-access programmes (i.e. outside a clinical trial) of patients with melanoma assigned to vemurafenib treatment. Outcomes included prevalence of dermatological toxicities treated with vemurafenib. Statistical analyses were performed using the R2.8.1 meta package. RESULTS: In total, 11 studies comprising 4197 patients were included in the meta-analysis. For patients assigned to vemurafenib, the overall prevalence of all-grade cutaneous squamous cell carcinoma (cSCC) was 18.00% (95% CI 12.00-26.00%), rash 45.00% (95% CI 34.00 57.00%), photosensitivity reaction (PR) 30.00% (95% CI 23.00-38.00%), keratoacanthoma (KA) 10.00% (95% CI 6.00-15.00%) and hand-foot skin reaction (HFSR) 9.00% (95% CI 4.00-20.00%), while the prevalence of high-grade events was: cSCC 16.00% (95% CI 11.00-23.00%), rash 12.00% (95% CI 3.00-38.00%), PR 4% (95% CI 2.00-8.00%) and KA 6.00% (95% CI 5.00-7.00%). CONCLUSION: The most frequent dermatological toxicities associated with vemurafenib treatment in patients with melanoma were cSCC, rash, PR and KA. These data may be useful for estimation of the efficacy and safety of the drug during clinical treatment and for reducing the prevalence of adverse reactions to vemurafenib treatment in patients with melanoma. PMID- 30280427 TI - The nose as the predominant site for pemphigus foliaceous. PMID- 30280428 TI - Carcass yields, muscle amino acid and fatty acid profiles, and antioxidant indices of broilers supplemented with synbiotic and/or organic acids. AB - The objective of the current research was to explore the possible impacts of dietary supplementation with synbiotic and/or organic acids (OA) on the performance traits, carcass yields and muscle amino acid and fatty acid (FA) profiles of broilers. Randomly, a total of 160 day-old chicks (Ross 308) were assigned into four equal groups (40 birds each), with each group subdivided into eight replicates (five birds/pen). The control group (CON) fed the basal diet with no supplements, while diets of the treated groups were supplemented with OA (Sodium butyrate 40%; 1 g/kg), synbiotic (comprised Bacillus subtilis, Saccharomyces cerivisiae, Streptococcus faecium, Mannan-Oligosaccharides and beta Glucan; 1 g/kg) and equal mix of OA and synbiotic (2 g/kg). Broilers fed the diets supplemented with synbiotic or synbiotic plus OA produced a significantly higher feed utilization efficiency (p = 0.021) and carcass yields (p = 0.038) than the CON and OA-supplemented groups. The group fed the diet supplemented with the synbiotic showed lowered serum cholesterol (p = 0.049), triglycerides (p = 0.001) and very low density lipoprotein (p = 0.032) when compared with the CON group. Regarding the polyunsaturated FA (PUFA) of breast muscles, synbiotic supplemented birds had significantly lower n-6:n-3 ratio (p = 0.047), however, a greater hypocholesterolaemic to hypercholesterolaemic FA (H/H) ratio was reported when compared with the CON group (p = 0.002). Among the essential amino acids, the contents of leucine and methionine in the breast (p = 0.032 and 0.007 respectively) and thigh (p = 0.023 and 0.003 respectively) muscles were greater in the synbiotic-supplemented birds compared with the CON group. In conclusion, the synbiotic-supplemented diet improved the PUFA:SFA, n-6:n-3 and H/H ratios by altering the FA composition of broiler muscles, which are important with regards to human health. PMID- 30280429 TI - Contribution of different rumen microbial groups to gas, short-chain fatty acid and ammonium production from different diets-an approach in an in vitro fermentation system. AB - In this study, the relative contribution of different microbial groups to ruminal metabolism was investigated for different diets. The rumen microbial cultures included whole rumen fluid, fungi + protozoa, bacteria + protozoa, protozoa and bacteria + fungi and were established by physical and chemical methods. Gas production, short-chain fatty acid (SCFA) and ammonium production were measured at 24 hr in in vitro incubations using the Hohenheim gas test (HGT) procedure. Seven donor animal diets with different concentrate-to-roughage ratios (C:R: 10:90, 30:70, 50:50, 70:30, 70:30BC (BC = NaHCO3 ), 90:10 and 90:10BC) and five HGT diets (C:R: 10:90, 30:70, 50:50, 70:30 and 90:10) were formulated. Incubations in the HGT were always based on inoculum from sheep diets with the respective C:R ratio. Gas and ammonium production increased (p < 0.001) as a result of a gradual increase in concentrate proportion of the diets. In general, SCFA production followed the same trend. Whole rumen fluid and bacteria + fungi produced approximately 50% higher gas volume than protozoa and fungi + protozoa fractions, whereas gas production with bacteria + protozoa was at an intermediate level. Coculture of protozoa either with bacteria or with fungi produced more ammonium. Populations without bacteria were characterized by a particularly high acetate/propionate ratio. Although an interaction between microbial group and diet was observed for several variables, no clear direction could be established. Manipulating rumen fluid by selectively suppressing specific rumen microbial groups may be a helpful tool in elucidating their role in nutrient degradation and turnover in vitro. PMID- 30280430 TI - Fast-Charging and High Volumetric Capacity Anode Based on Co3 O4 /CuO@TiO2 Composites for Lithium-Ion Batteries. AB - This paper presents an investigation of anodic TiO2 nanotube arrays (TNAs), with a Co3 O4 /CuO coating, for lithium-ion batteries (LIBs). The coated TNAs are investigated using various analytical techniques, with the results clearly suggesting that the molar ratio of Co3 O4 /CuO in the TiO2 nanotubes substantially influences its battery performance. In particular, a cobalt/copper molar ratio of 2:1 on the TNAs (Co2 Cu1 @TNAs) features the best LIBs anode performance, exhibiting high reversible capacity and enhanced cycling stability. Noticeably, Co2 Cu1 @TNAs achieve excellent rate capability even after quite a high current density of 20.0 A g-1 (~25 C, where C corresponds to complete discharge in 1 h) and superior volumetric reversible capacity of ~3330 mA h-1 cm 3 . This value is approximately seven times higher than those of a graphite-based anode. This outstanding performance is attributed to the synergistic effects of Co2 Cu1 @TNAs: 1) the structural advantage of TNAs, with their large amount of free space to accommodate the large volume expansion during Li+ insertion/extraction and 2) the optimized ratio of Co3 O4 and CuO in the composite for improved capacity. In addition, no binder or conductive agent is used, which is partly responsible for the overall improved volumetric capacity and electrochemical performance. PMID- 30280431 TI - Synthesis of Biomass-Derived Carbon Induced by Cellular Respiration in Yeast for Supercapacitor Applications. AB - Because activated carbon is extensively used in supercapacitors, optimization of its precursors and synthetic strategies are crucial. Inspired by the rich sugar content of banana peel waste, which can be transformed through the respiration of yeast into alcohol with the release of CO2 , we developed an environmentally benign and highly efficient process for the production of renewable heteroatom doped hierarchical porous carbon materials (yeast-treated banana-peel-based carbon, denoted as YBP) without any additional templates or activation agents. The resulting biologically activated carbon was characterized by near-edge X-ray absorption fine-structure spectroscopy, X-ray photoelectron spectroscopy, and other physical methods. The biologically activated carbon achieved a maximum gravimetric specific capacitance of 476 F g-1 in 1 m H2 SO4 electrolyte. Remarkably, with a moderate specific surface area of 1084 m2 g-1 , the as obtained activated carbon was found to have a high packing density. With enriched pseudocapacitance sites, the YBP symmetric supercapacitor has a high volumetric specific capacitance and energy density (maximum values of 264 F cm-3 and 23.5 Wh L-1 , respectively). The supercapacitor showed superior cyclic stability, with 94 % capacitance retention for voltage values up to 1.6 V after 10 000 cycles, which confirmed the promising application of this supercapacitor in miniature electronic devices. PMID- 30280432 TI - Sleeping beauty transposon-mediated poly(A)-trapping and insertion mutagenesis in mouse embryonic stem cells. AB - Saturation mutagenesis of all endogenous genes within the mouse genome remains a challenging task, although a plenty of gene-editing approaches are available for this purpose. Here, a poly(A)-trap vector was generated for insertion mutagenesis in mouse embryonic stem (mES) cells. This vector contains an expression cassette of neomycin (Neo)-resistant gene lacking a poly(A) signal and flanked by two inverted terminal repeats of the Sleeping Beauty (SB) transposon. The whole poly(A)-trap cassette can transpose into target TA dinucleotides, properly splice with endogenous genes and effectively interrupt the transcription of trapped genes in mES cells after transient induction of SB expression by doxycycline (DOX)-treatment at 1 MUg/ml, leading to the formation of multiple geneticin (G418)-resistant cell clones. In the first round of mutation screening, we identified six transposition events from 23 cell clones, including four inserted into an endogenous gene and two landed between endogenous genes. The abilities of self-renewal, totipotency, genetic stability and differentiation of syngap1+/- cells were not affected by DOX-treatment and G418-selection. These findings suggest that this SB transposon-mediated poly(A)-trap vector can be used as an alternative tool for a large-scale screening of mES cells with a gene mutation and for further generation of mutant mouse strains.

PMID- 30280433 TI - Medium-chain glycerides affect gut morphology, immune- and goblet cells in post weaning piglets: In vitro fatty acid screening with Escherichia coli and in vivo consolidation with LPS challenge. AB - The influence of medium-chain glycerides on performance and gastrointestinal well being in weaning piglets was assessed. First, caproic (C6), caprylic (C8) and capric (C10) acid activity against Escherichia coli was screened in vitro. Pig flora of the whole small intestine was used as inoculum. Seven in vitro incubations were done in duplicate at pH = 3 and 5: C10 (15 mM), C8 (12 mM), C6 (15, 12, 10 mM), a non-incubated-negative control and incubated negative control. Culture suspensions were plated on E. coli-selective agar. Controls showed bacterial growth. C6 and C8 showed no growth at both pH-values, where C10 showed growth at pH = 5. Secondly, an in vivo study was done with 80 weaned piglets over 42 days, housed in pens of eight animals (five pens/treatment), fed a basal diet containing broken rice/soya bean meal/fish meal and supplemented with C6 and C8 in medium-chain glyceride form (MCT6/8, 0.175%) or antibiotic growth promoter (AGP, 0.020%) (Kasetsart University, Thailand) serving as control. Feed intake, daily gain and feed-to-gain ratio did not differ between MCT6/8 and AGP. Per replicate, two random selected piglets were challenged intravenously with E. coli lipopolysaccharide (LPS) or saline solution (S) at Days 21 and 28. All challenged animals were sacrificed; blood and digestive tract samples (jejunum/ileum) were collected at Day 35. LPS challenge consistently reduced villus height and crypt depth for MCT6/8 and AGP. However, LPS-challenged piglets supplemented with MCT6/8 restored villus height, where AGP did not. MCT6/8 piglets had higher serum IgA, more jejunal IgA-positive plasma cells and goblet cells than AGP. At the ileal level, results were similar, though less pronounced. The present study offers new insight in the benefits of MCT6/8 over AGP in the post-weaning period. There is in vitro anti-microbial action of C6 and C8 on E. coli. In vivo, MCT6/8 also has protective effects in the small intestine that may result in growth promotion. PMID- 30280434 TI - Application of Six Sigma for evaluating the analytical quality of tumor marker assays. AB - CONTEXT: The results of detection assays for the same specimen are usually quite different in different laboratories or when tested with different detection systems. OBJECTIVE: This study was designed to investigate the value of applying sigma metrics derived from different standards for allowable total error (TEa) in evaluating the analytical quality of tumor marker assays. METHODS: Assays were evaluated for these six tumor markers: total prostate-specific antigen (tPSA), carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), carbohydrate antigen 199 (CA199), carbohydrate antigen 125 (CA125), and carbohydrate antigen 153 (CA153). Sigma values were calculated for two concentrations of quality control products to assess differences in quality of tumor marker assays. Improvement measures were recommended according to the quality goal index, and appropriate quality control rules were selected according to the sigma value. RESULTS: The sigma value was highest using the higher biological variation-derived "appropriate" TEa standard: it was sigma >=6 or higher in 16.7% of tumor markers. Sigma was below 6 for all tumor markers using the other three TEa. CEA, AFP, CA199, CA125, and CA153 required improved precision. The marker tPSA required improve precision and accuracy. According to sigma values by using China's external quality assessment standards, CEA, AFP, CA125, and CA153 require 13s /22s /R4s /41s multirules for internal quality control, CA199 requires use of 13s /22s /R4s /41s /8x multirules, and tPSA requires maximum quality control rules. CONCLUSION: Six Sigma is useful for evaluating performance of tumor markers assays and has important application value in the quality control of these assays.

AB - BACKGROUND: Coeliac disease is an autoimmune disorder triggered by the ingestion of gluten. In recent years, there has been considerable increase in the availability of gluten-free products in North America. The present study investigated how the recent proliferation of the gluten-free industry has affected individuals living with coeliac disease, with a primary focus on their social lives and relationships. METHODS: Interpretive phenomenology was utilised for study design and analysis. Semi-structured interviews were conducted with 17 adults diagnosed with coeliac disease in Calgary, Alberta. Interviews were audio recorded and then transcribed for analysis. RESULTS: People living with coeliac disease experience the growth of the gluten-free industry as a 'double-edged sword'. Although they are grateful for more palatable gluten-free options, they are increasingly faced with misunderstandings about the severity of coeliac disease as a result of many noncoeliac disease individuals subscribing to the gluten-free diet. This 'double-edged sword' made certain types of social situations more easily manageable (e.g. more gluten-free options available at restaurants), whereas others produced distress (e.g. increased risk of inadvertently consuming gluten). Participants also felt they may be perceived or even perceived themselves differently (e.g. felt high maintenance). To help mitigate these social ramifications of following the gluten-free diet, participants utilised various strategies. CONCLUSIONS: The sole medical recommendation of a gluten-free diet fails to acknowledge the ongoing difficulties those with coeliac disease can endure in the current gluten-free landscape.

AB - RATIONALE: Quantification of small molecules by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) is challenging yet attractive, due to micro-scale procedural simplicity, high throughput and lack of memory effects. Since these features are important while analyzing trace elements in quality control schemes, MALDI-TOFMS was used for the determination of copper (Cu) and lead (Pb) in tequila with quantification carried out by partial least squares regression (PLS2) and by univariate calibration (UC). METHODS: In the proposed procedure, Bi(III) was added as internal standard (IS), diethyldithiocarbamate complexes were formed (pH 7.4) and extracted into chloroform; after solvent evaporation and re-constitution in acetonitrile, the sample was co-crystallized with alpha-cyano-4-hydroxycinnamic acid on a steel target. From the acquired mass spectra, UC was performed using IS-normalized signals of the monoisotopic ions of analytes, and the m/z range 350-513 was used for PLS2. Accuracy was tested by recovery experiments and by inductively coupled plasma (ICP)-MS analysis. RESULTS: When compared with direct analyte signal measurements, application of IS yielded enhanced analytical performance using either UC or PLS2; the method quantification limits were: 11.1 MUg L-1 , 23.4 MUg L-1 for Cu and 89.8 MUg L-1 , 97.1 MUg L-1 for Pb, respectively. In tequila, MALDI-TOFMS and ICP-MS provided consistent results for Cu (165-2599 MUg L-1 ); Pb was not detected in any sample by MALDI-TOFMS, yet recoveries obtained after standard addition were indicative of acceptable accuracy (400 MUg L-1 Pb added; recoveries: 91.2-108% for UC and 98.8-120% for PLS2). CONCLUSIONS: New experimental evidence has been provided supporting the inclusion of trace metals quantification within a range of MALDI-TOFMS applications. Slightly better results were obtained for UC as compared with PLS2 yet both methods can be recommended for testing the compliance of Cu and Pb levels with Official Mexican Norm. Of note, while using PLS2, there is no need for signal integration nor for IS normalization.

AB - RATIONALE: Elental(r) is an elemental diet widely used as a nutritional supplement for Crohn's disease (CD) patients in Japan. Elental(r) contains amino acids as N-sources and does not contain selenium (Se), and the delta13 C and delta15 N values of Elental(r) are markedly higher and lower, respectively, than those of normal diet. METHODS: We compared the delta13 C and delta15 N values and Se concentration in the scalp hair of CD patients with those of control subjects who ate a regular diet, and estimated the amount of Elental(r) ingested as a supplement. The delta13 C and delta15 N values and the Se concentration were quantified using IRMS and ICP-MS, respectively. RESULTS: An increase of Elental(r) ingestion increased the delta13 C value in the hair of CD patients (p<0.05), while it reduced the delta15 N value (p<0.05) and tended to reduce the Se concentration in female patients. CONCLUSIONS: The amount of Elental(r) ingested could be estimated by the delta13 C and delta15 N values in the hair of CD patients. Furthermore, the Se deficiency in female patients may be predicted from the delta13 C and delta15 N values.

AB - Drug-induced Pavlovian memories are thought to be crucial for drug addiction because they guide behaviour towards environments with drug availability. Drug related memory depends on persistent changes in dopamine-glutamate interactions in the medial prefrontal cortex (mPFC), basolateral amygdala, nucleus accumbens core and hippocampus. Recent evidence from our laboratory indicated that the cerebellum is also a relevant node for drug-cue associations. In the present study, we tested the role that specific regions of the cerebellum and mPFC play in the acquisition of cocaine-induced preference conditioning. Quinolinic acid was used to manage a permanent deactivation of lobule VIII in the vermis prior to conditioning. Additionally, lidocaine was infused into the prelimbic and infralimbic (IL) cortices for reversible deactivation before every training session. The present findings show, for the first time, that the cerebellum and mPFC might act together in order to acquire drug-cue Pavlovian associations. Either a dorsal lesion in lobule VIII or an IL deactivation encouraged cocaine induced preference conditioning. Moreover, simultaneous IL-cerebellar deactivation prevented the effect of either of the separate deactivations. Therefore, similar to the IL cortex, neural activity in the cerebellum may be crucial for ensuring inhibitory control of the expression of cocaine-related memories. PMID- 30280440 TI - Gas-phase rearrangement reaction of Schiff-base-modified peptide ions. AB - RATIONALE: Schiff base modification of peptides has been shown to facilitate their primary structural characterization via tandem mass spectrometry. However, we have discovered a novel rearrangement reaction via ion trap collisional activation involving the imine of the Schiff base and one of several functional groups, particularly the side chains of the basic residues lysine, arginine, and histidine, in the peptide. METHODS: Gas-phase ion/ion reactions involving an aldehyde-containing reagent were used to generate Schiff-base-modified model peptides in a hybrid triple quadrupole/linear ion trap tandem mass spectrometer. Subsequent ion trap collisional activation was used to study the rearrangement reaction. RESULTS: Schiff-base-modified peptide ions were found to undergo a rearrangement reaction that was observed to be either a major or minor contributor to the product ion spectrum, depending upon a variety of factors that include, for example, ion polarity, identity of the nucleophile in the peptide (e.g., side chains of lysine, histidine, and arginine), and the position of the nucleophile relative to the imine. CONCLUSIONS: Relatively low-energy rearrangement reactions can occur in Schiff-base-modified peptide ions that involve the imine of the Schiff base and a nucleophile present in the polypeptide. While this rearrangement process does not appear to compromise the structural information that can be generated via collisional activation of Schiff base-modified peptide ions, it can siphon away signal from the structurally diagnostic processes in some instances.

PMID- 30280442 TI - Synthesis of the Highly Branched Hexasaccharide Core of Chlorella Virus N-Linked Glycans. AB - Chlorella viruses produce N-linked glycoproteins with carbohydrate moieties that differ in structure from all other N-linked glycans. In addition, unlike most viruses, these organisms do not hijack the biosynthetic machinery of the host to make glycocoproteins; instead, they produce their own carbohydrate-processing enzymes. A better understanding of the function and assembly of these fascinating and structurally-unprecedented glycans requires access to probe molecules. This work describes the first synthesis of a chlorella virus N-linked glycan, a highly branched hexasaccharide that contains the pentasaccharide present in all of the >15 structures reported to date. The target molecule includes a glucosyl asparagine linkage and a "hyperbranched" fucose residue in which all of the hydroxyl groups are glycosylated. Both convergent and linear approaches were investigated with the latter being successful in providing the target in 16 steps and 13 % overall yield. PMID- 30280443 TI - A developmental cascade model for early adolescent-onset substance use: the role of early childhood stress. AB - BACKGROUNDS AND AIMS: Despite the link between stress and addictive behavior in adulthood, little is known about how early life stress in families predicts the early emergence of substance use in adolescence. This study tested a developmental cascade model, proposing that early stressful life events and negative parent-child interaction covary, and both disrupt the refinement of inhibitory control, which evolves into problem behavior in middle/late childhood and subsequent substance use exploration in early adolescence. METHODS: Data came from the Early Steps Multisite study, a community sample of at-risk families in the metropolitan US areas of Pittsburgh (Pennsylvania), Eugene (Oregon) and Charlottesville (Virginia) with children aged 2 years at the start of the study and 14 years at the last measurement (n = 364). Structural equation modeling was used to test the proposed model. RESULTS: Early stressful life events and negative parent-child interaction assessed at ages 2-5 were negatively related to inhibitory control at ages 7 and 8. Low levels of inhibitory control were prognostic of childhood problem behavior at ages 9 and 10. Finally, late childhood problem behavior was associated with substance use at age 14. Parental drug use was directly related to substance use at age 14. CONCLUSIONS: Early life stress may disrupt child inhibitory control, which can cascade into behavioral and peer problem behavior in childhood and, in turn, heighten the risk for early adolescent substance use. PMID- 30280444 TI - A new UHPLC-MS/MS method for the direct determination of strigolactones in root exudates and extracts. AB - INTRODUCTION: Strigolactones (SLs) are the most representative germination stimulants for seeds of root parasitic plants, and they show activity even at concentrations below 10-10 M. The low amounts of stimulants produced by the host and their rapid degradability make it crucial to develop analytical methods with very low limits of quantification. OBJECTIVE: To develop a sensitive and validated analytical method for the simultaneous quantification of seven SLs [7 oxoorobanchyl acetate (1), solanacol (2), orobanchol (4), strigol (5), fabacyl acetate (6), orobanchyl acetate (7), and 5-deoxystrigol (8)]. METHODS: SLs were analysed using ultra-high performance liquid chromatography coupled to tandem mass spectrometry (UHPLC-MS/MS), with (+/-)-GR24 (3) employed as internal standard (IS). Validation was based on selectivity, linearity, precision of the peak areas (repeatability and intermediate precision), detection and quantification limits, and stability. RESULTS: A simple, rapid and reliable UHPLC MS/MS method has been validated for the routine analysis of seven SLs and has been successfully applied to quantify them in exudates and extracts from tomato roots (Solanum lycopersicum). The limits of quantifications range from 0.05 MUg/L for 5-deoxystrigol to 0.96 MUg/L for solanacol. CONCLUSION: The method provides a useful tool for research in all the fields related to SLs, both for studies related to their function as hormones, and signalling molecules in the rhizosphere, without sample preparation required for extracts and root exudates in less than 11 minutes. PMID- 30280445 TI - The mir-200 family regulates key pathogenic events in ascending aortas of individuals with bicuspid aortic valves. AB - BACKGROUND: An individual with a bicuspid aortic valve (BAV) runs a substantially higher risk of developing aneurysm in the ascending aorta compared to the normal population with tricuspid aortic valves (TAV). Aneurysm formation in patients with BAV and TAV is known to be distinct at the molecular level but the underlying mechanisms are undefined. Here, we investigated the still incompletely described role of microRNAs (miRNAs), important post-transcriptional regulators of gene expression, in such aortic disease of patients with BAV as compared with TAV. METHODS AND RESULTS: Using a system biology approach, based on data obtained from proteomic analysis of non-dilated aortas from BAV and TAV patients, we constructed a gene-interaction network of regulatory microRNAs associated with the observed differential protein signature. The miR-200 family was the highest ranked miRNA, hence potentially having the strongest effect on the signalling network associated with BAV. Further, qRT-PCR and ChIP analyses showed lower expression of miR-200c, higher expression of miR-200 target genes, ZEB1/ZEB2 transcription factors, and higher chromatin occupancy of the miR-200c promoter by ZEB1/ZEB2 in BAV patients, indicating a miR-200c/ZEBs negative feedback loop and induction of endothelial/epithelial mesenchymal transition (EndMT/EMT). CONCLUSION: We propose that a miR-200-dependent process of EndMT/EMT is a plausible biological mechanism rendering the BAV ascending aorta more prone to aneurysm development. Although initially supported by a miR-200c/ZEB feedback loop, this process is most probably advanced by cooperation of other miRNAs. PMID- 30280446 TI - Oligonol, a low-molecular-weight polyphenol derived from lychee peel, attenuates diabetes-induced pancreatic damage by inhibiting inflammatory responses via oxidative stress-dependent mitogen-activated protein kinase/nuclear factor-kappa B signaling. AB - This study investigated the effects of oligonol, a low-molecular-polyphenol derived from lychee peel, against diabetes-induced pancreatic damage via oxidative stress-induced inflammation. Oligonol was orally administered at 10 or 20 mg/kg body weight/day for 10 days to streptozotocin-induced diabetic rats, and the rats were compared with nondiabetic and diabetic control rats. The diabetic rats showed loss of body weight and increased pancreatic weight, and the oral administration of oligonol attenuated these parameters. Moreover, the administration of oligonol caused a significant decrease in the serum glucose level and a significant increase in the serum and pancreatic insulin and C peptide levels in the diabetic rats. Oligonol also significantly reduced the enhanced levels of reactive oxygen species and 2-thiobarbituric acid reactive substance, which are oxidative stress biomarkers, in the serum and pancreas. Oligonol treatment reduced the overexpression of phospho-p38, phospho-ERK1/2, phospho-inhibitor of nuclear factor-kappa B (NF-kappaB), NF-kappaBp65, and NF kappaBp65-induced inflammatory protein such as cyclooxygenase-2, inducible nitric oxide synthase, tumor necrosis factor-alpha, and interleukin-6. Furthermore, oligonol treatment led to significantly attenuated histological damage in the pancreas. On the basis of these results, we conclude that a plausible mechanism of oligonol's antidiabetic action may be its antioxidative stress-related anti inflammatory action. PMID- 30280447 TI - Characterisation and screening of antimicrobial essential oil components against clinically important antibiotic-resistant bacteria using thin layer chromatography-direct bioautography hyphenated with GC-MS, LC-MS and NMR. AB - INTRODUCTION: The antimicrobial activity of many essential oils (EOs) is well established, indicating that EOs may be a source of compounds for antimicrobial drug development. Thin layer chromatography-direct bioautography (TLC-DB) can quickly identify antimicrobial components in complex mixtures and can be applied to the screening of EOs for lead compounds. OBJECTIVES: This study aimed to identify antimicrobial components of oregano, rosewood and cumin EOs against antibiotic-sensitive and -resistant bacteria using TLC-DB and a multi-faceted approach of GC-MS, LC-MS and NMR techniques to characterise bioactive compounds. The study also aimed to quantify the antimicrobial activity of bioactive compounds in order to evaluate their potential for the development of therapies against antibiotic-resistant bacteria. MATERIALS AND METHODS: EOs were eluted on TLC plates and sprayed with a suspension of Staphylococcus aureus, Enterococcus faecium, Escherichia coli or Pseudomonas aeruginosa (antibiotic-sensitive and resistant isolates). Zones of inhibition, visualised with iodonitrotetrazolium chloride, were subject to GC-MS, LC-MS and NMR to characterise the bioactive compounds. RESULTS: Seven compounds were identified from the three EOs using GC MS, while LC-MS and NMR failed to detect the presence of any further non-volatile or heat labile compounds. Carvacrol was most antimicrobial compound identified, with minimum inhibitory concentrations ranging 0.99-31.62 mM. CONCLUSION: The identified antimicrobial compounds present in oregano, rosewood and cumin EOs including carvacrol may be candidates for the development of novel antimicrobial therapies against antibiotic-resistant bacteria. PMID- 30280448 TI - Understanding an emerging treatment population: Protocol for and baseline characteristics of a prospective cohort of people receiving treatment for pharmaceutical opioid dependence. AB - INTRODUCTION AND AIMS: Despite large increases in pharmaceutical opioid dependence and related mortality, few studies have focused on the characteristics and treatment experiences of those with pharmaceutical opioid dependence. We describe the formation of a prospective cohort of people receiving treatment for pharmaceutical opioid dependence and describe their baseline characteristics. DESIGN AND METHODS: People who had entered treatment for pharmaceutical opioid dependence (n = 108) were recruited through drug treatment services in New South Wales, Australia. We describe baseline characteristics of those that commenced pharmaceutical opioids for pain or other reasons and conducted a thematic analysis of responses regarding their treatment experience. RESULTS: Mean age was 41 years (SD 11), half were male (48%). Just over half reported lifetime heroin use (57%). Oxycodone (49%) and codeine (29%) were the most common opioids reported. Most (85%) reported past-year problematic pain, 38% reported chronic pain. Half (52%) reported moderate to severe depression symptoms. Most (66%) commenced opioids for pain, and this group were older, less likely to report a previous overdose and less likely to report use of illicit drugs compared to those commencing for other reasons. Five themes related to treatment expectations: (i) stigma; (ii) the restrictive nature of treatment; (iii) knowledge; (iv) pain; and (v) positive experience with buprenorphine. DISCUSSION AND CONCLUSIONS: This study describes the complexities in an important emerging treatment population of pharmaceutical opioid-dependent people. Findings highlights that addressing knowledge and perceptions around treatment may be critical to address the rising mortality associated with pharmaceutical opioid dependence. PMID- 30280449 TI - An inclusive, online Delphi process for setting targets for best practice implementation for spinal cord injury. AB - RATIONALE, AIMS, AND OBJECTIVES: The Spinal Cord Injury Knowledge Mobilization Network is a pan-Canadian community of practice composed of seven rehabilitation hospitals. The goal of this network is to utilize implementation science processes to facilitate the adoption of best practice in spinal cord injury (SCI) rehabilitation. In addition to selecting specific practices for implementation, a key aspect of effective implementation is the engagement of stakeholders in decision-making processes. To achieve this, the network utilized a Delphi process to reach consensus on two pressure ulcer prevention and management practices to be implemented in SCI inpatient rehabilitation. A diverse, multidisciplinary panel of clinicians, researchers, sponsoring agency representatives, and persons with SCI participated in this process. METHOD: An online Delphi process was conducted in order to prioritize pressure ulcer prevention and management best practice recommendations and performance indicators for implementation. The process was conducted in six stages: (1) steering committee selection; (2) identification and selection of evidence; (3) participant selection and recruitment; (4) survey development; (5) identification of voting criteria; and (6) five rounds of voting. RESULTS: The Delphi process resulted in the selection of two best practices: (1) comprehensive risk assessment and (2) education for pressure ulcer prevention and management in persons with SCI. CONCLUSIONS: In this Delphi process, a large expert panel achieved consensus on best practice recommendations and associated performance indicators for implementation. This process was undertaken as a first step towards optimization of service delivery and outcomes for persons with SCI across Canada. PMID- 30280450 TI - Case series and systematic review of acquired diaphragmatic hernia after liver transplantation. AB - BACKGROUND: ADH is a rare and potentially fatal complication following LT. In this study, a systematic review was completed to identify risk factors which may contribute to ADH. METHODS: Transplant databases at three LT programs were reviewed. Four pediatric and zero adult cases were identified. Next, a systematic review was completed. Fourteen studies describing 41 patients with ADH were identified. Patient demographics, transplant characteristics, and features of ADH diagnosis were examined. RESULTS: The majority (90.2%) of ADH were in children. In pediatric LT, 95.1% received a segmental allograft. ADH occurred in the right P diaphragm 92.7% of the time, and 87.8% were repaired primarily. Patient demographics, post-transplant complications, and immunosuppression regimens were broad and failed to predict ADH. Most patients presented with either respiratory or gastrointestinal symptoms. There were two pediatric deaths related to undiagnosed ADH. The combined worldwide incidence of ADH in pediatric LT is 1.5% (34/2319 patients). CONCLUSION: ADH is a rare complication post-LT that primarily occurs in pediatric recipients. When diagnosed early, ADH can be repaired primarily with good outcomes. PMID- 30280451 TI - Unravelling the role and mechanism of adipokine and gastrointestinal signals in animal models in the nonhomeostatic control of energy homeostasis: Implications for binge eating disorder. AB - Central and peripheral signals regulating energy homeostasis interact tightly with neuronal pathways to modulate the hedonic component of food intake. Dysregulation of these interactions could explain the development of binge eating disorder (BED) and/or obesity and the increasing incidence of food addiction. In this review, we have highlighted the crucial role of peripheral hormones, such as leptin and ghrelin, among others, in these nonhomeostatic pathways. We have also emphasised the relevance of central cannabinoid pathway and lateral hypothalamus, with orexin and melanin-concentrating hormone neurons, as the critical hub controlling motivation and reward. Throughout the manuscript, we have focused on mechanisms learned from animal models of BED/food addiction in order to understand how these peripheral signals can modulate the motivation to eat. Understanding these mechanisms could help us to develop new treatment options for BED and/or obesity.

PMID- 30280453 TI - Patient-reported health-related quality of life outcomes in supportive-care interventions for adults with brain tumors: A systematic review. AB - OBJECTIVES: The objectives of this systematic review were to (a) identify supportive-care (psychosocial/behavioral, pharmacological, complementary, or alternative) interventions that have been evaluated via randomized controlled trials (RCTs) to improve patient-reported health-related quality of life (HRQoL) among adults with brain tumors, (b) evaluate the quality of the intervention studies, and (c) evaluate if developed interventions have been efficacious at improving HRQoL, as compared with control conditions in RCTs. METHODS: This systematic review was conducted using preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Four databases were searched for RCTs of supportive-care interventions for adults with brain tumors, primary or metastatic, that included a patient-reported HRQoL outcome. Quality of the included studies was assessed using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. RESULTS: Ten RCTs involving 640 patients with either a primary or metastatic brain tumor investigating supportive care interventions with a HRQoL outcome were identified. In terms of quality, three of the studies received a "strong" rating, three received a "moderate" rating, and four of the studies received a "weak" rating. Only two of the interventions (ie, a home-based psychosocial intervention and individualized acupuncture with standard rehabilitation) demonstrated improvements in HRQoL over control conditions. CONCLUSIONS: HRQoL is of the utmost importance when treating patients with brain tumors. Yet there is a notable paucity of research to inform clinical decisions and evidence-based practice. More high-quality studies of interventions aimed at improving HRQoL are needed. PMID- 30280455 TI - Novel technique for pediatric living donor liver transplantation in patients with portal vein obstruction: The "pullout technique". AB - PV hypoplasia may increase the risk of posttransplant complications, especially when it extends to near the SMV and SpV junction. We described our experience of 10 pediatric cases of PV hypoplasia/thrombus in which the pullout technique was required for PV reconstruction. There were five male and five female patients. The median age was 9 months, and the median weight was 8.1 kg. The indications for the pullout technique were PV hypoplasia in seven patients and PV thrombus in 3. The inflow sites of the enlarged LGV were as follows: the main PV trunk (n = 2), the SMV and SpV junction (n = 4), and the SpV (n = 4). The posterior face of the pancreas was tunneled along the PV, and the PV was returned to its original position with or without the use of an interposed vein graft. The pullout technique created a good operative field, which allowed for the complete removal of the hypoplastic PV or thrombectomy with the safe use of various interposed vein grafts. PMID- 30280456 TI - Construction of a risk prediction model of vancomycin-associated nephrotoxicity to be used at the time of initial therapeutic drug monitoring: A data mining analysis using a decision tree model. AB - OBJECTIVES: In our previous study, we built a risk prediction model of vancomycin (VCM)-associated nephrotoxicity using decision tree (DT) analysis. However, this has several limitations in clinical applications. Our objective here was to construct a clinically applicable risk prediction model to be used at the time of initial therapeutic drug monitoring (TDM), in patients with uncomplicated infections. METHOD: A retrospective study was conducted at Hokkaido University Hospital. Subjects that had received VCM were extracted between November 2011 and April 2017. Nephrotoxicity was defined as an increase in serum creatinine of 0.5 mg/dL or 50% or higher from baseline. The additional inclusion criteria in this study were as follows: (1) the target trough level of VCM was set to 10 to 15 mg/L, and (2) the duration of therapy was 7 to 14 days. Patients were assumed to have uncomplicated infections. Risk factors for nephrotoxicity were evaluated, which could be extracted at the initial TDM. In the DT analysis, a chi-squared automatic interaction detection algorithm was constructed. RESULTS: A total of 402 patients were enrolled, and 56 (13.9%) patients developed nephrotoxicity. In the DT analysis, concomitant medications (furosemide, piperacillin-tazobactam, and vasopressor drugs) and an initial VCM trough concentration >= 15.0 mg/L were extracted as predictive variables by which patients were divided into six subgroups. The incidence of nephrotoxicity was 5.2% to 70.0%, with subgroups classified as low to high risk of nephrotoxicity. The accuracy of DT model was favourable (87.1%). CONCLUSION: We propose that the DT model built in this study is applicable to clinical practice. PMID- 30280457 TI - Knowledge about risk factors for falls and practice about fall prevention in older adults among physiotherapists in Nigeria. AB - BACKGROUND AND OBJECTIVE: Falling is a major health concern that has contributed significantly to older people's injury and loss of life worldwide, warranting the development of fall-prevention strategies, the success of which has been attributed to the levels of knowledge and practice about fall prevention among physiotherapists and other health professionals. The objective of this study was to determine the self-reported levels of knowledge on risk factors of fall and practices about fall prevention in older adults among physiotherapists in Nigeria. METHODS: Physiotherapists (N = 237) recruited from the six geopolitical zones of Nigeria completed a three-part structured questionnaire that asked questions about risk factors for fall and common practices for fall prevention using a 5-point-rated Likert scale. Data were analysed using descriptive analysis, chi-square, and Kruskal-Wallis tests. RESULTS: Among physiotherapists in Nigeria, 89% rated their level of knowledge about preventing falls among older adults as high, and 64% of them rated their level of practice on this topic as high. Among the individual items that measured knowledge, 40% of the participants reported a moderate level of knowledge about multiple medications as a risk factor for falls. Fifty percent of the participants reported a low level of practice of referral to other health care professionals, whereas 40% and 41% reported a moderate level of practice on documenting risk factors and treatment plans, respectively. There was no association between age, gender, or years of practice with levels of knowledge or practice. CONCLUSION: This study suggests that physiotherapists in Nigeria have adequate knowledge and practice for fall prevention in older adults. However, there are potential gaps in knowledge of risk factors, documentation, and referrals to other professions that may be addressed through developing context-specific fall-prevention clinical guidelines for practice in Nigeria. PMID- 30280458 TI - Synthesis of the Campylobacter jejuni 81-176 Strain Capsular Polysaccharide Repeating Unit Reveals the Absolute Configuration of its O-Methyl Phosphoramidate Motif. AB - The O-methyl phosphoramidate (MeOPN) motif is a non-stoichiometric modification of capsular polysaccharides (CPS) in ~70 % of all Campylobacter jejuni strains. Infections by C. jejuni lead to food-borne illnesses and the CPS they produce are key virulence factors. The MeOPN phosphorus atom in these CPS is stereogenic and is found as a single stereoisomer. However, to date, the absolute stereochemistry at this atom has been undefined. We report the synthesis of the three repeating units found in C. jejuni 81-176 CPS; one of these possesses a MeOPN group. In the course of these studies we established that the stereochemistry of the phosphorus atom in this MeOPN group is R. These studies represent the first unequivocal proof of stereochemistry of this group in any C. jejuni CPS. The compounds produced are anticipated to be useful tools in investigations targeting the function and biosynthesis of this structurally-interesting modification, which so far has only been identified in campylobacter. PMID- 30280459 TI - Effect of selenium supplementation on changes in HbA1c: Results from a multiple dose, randomized controlled trial. AB - AIM: To investigate the effect of selenium supplementation at different dose levels on changes in HbA1c after 6 months and 2 years in a population of low selenium status. MATERIALS AND METHODS: The Denmark PRECISE study was a single centre, randomized, double-blinded, placebo-controlled, multi-arm, parallel clinical trial with four groups. In total, 491 volunteers aged 60 to 74 years were randomly assigned to treatment with 100, 200 or 300 MUg selenium/day as selenium-enriched yeast or placebo-yeast. HbA1c measurements were available for 489 participants at baseline, 435 at 6 months, and 369 after 2 years of selenium supplementation. Analyses were performed by intention to treat. RESULTS: The mean (SD) age, plasma-selenium concentration, and blood HbA1c at baseline were 66.1 (4.1) years, 86.5 (16.3) ng/g and 36.6 (7.0) mmol/mol, respectively. During the initial 6-month intervention period, mean HbA1c (95% CI) decreased by 1.5 (-2.8 to -0.2) mmol/mol for 100 MUg/d of selenium supplementation and by 0.7 (-2.0 to 0.6) mmol/mol for the 200 and 300 MUg/d groups compared with placebo (P = 0.16 for homogeneity of changes across the four groups). After 2 years of selenium supplementation, HbA1c had decreased significantly in all treatment groups, with no difference between active treatment and placebo. CONCLUSIONS: Selenium supplementation in an elderly European population of low selenium status did not significantly affect HbA1c levels after 2 years. Our findings corroborate a possible U-shaped response of selenium supplementation on glucose metabolism.

PMID- 30280461 TI - Fibrosis-matched outcomes between chronic hepatitis B patients with drug-induced virological response and inactive carriers. AB - BACKGROUND & AIMS: We compared the risk of hepatocellular carcinoma (HCC) development between patients with chronic hepatitis B (CHB) who achieved virological response (VR; HBV-DNA < 2000 IU/mL) with nucleos(t)ide analogues (NUCs) treatment (NUC-VR group) and patients with inactive CHB phase (ICHBP group). METHODS: To adjust for imbalances between NUC-VR and ICHBP groups, propensity score matching (PSM) models with 1:1 ratios were performed. RESULTS: This study included 2032 patients (n = 1291 in NUC-VR group and n = 741 in ICHBP group). Before PSM, NUC-VR group was at higher risk of HCC development than ICHBP group at 7 years (9.4% in NUC-VR group vs 3.3% in ICHBP group; P < 0.001). However, after PSM, the cumulative HCC development rates at 7 years were similar in NUC-VR and ICHBP groups using the three PSM models [2.0% vs 4.3%, PSM model-1 (612 pairs); 3.7% vs 4.4%, PSM model-2 (618 pairs); and 2.4% vs 4.3%, PSM model-3 (610 pairs)] (all P > 0.05). CONCLUSIONS: After adjusting heavier hepatic fibrosis burden in NUC-VR group, overall clinical outcomes between 2 groups had become comparable. Therefore, if appropriate, NUCs to prevent viral replication and hepatic inflammation are required for achieving better prognosis. PMID- 30280462 TI - Risk factors of pre-hypertension and hypertension among non-pregnant women of reproductive age in northeastern Tanzania: a community based cross-sectional study. AB - OBJECTIVES: To determine risk factors of pre-hypertension and hypertension in a cohort of 1247 rural Tanzanian women before conception. METHODS: Demographic and socioeconomic data, anthropometric measurements, past medical and obstetric history and other risk factors for pre-hypertension and hypertension were collected using a structured questionnaire. Multiple logistic regression analysis was used to evaluate the associations between anthropometric indices and other risk factors of pre-hypertension and hypertension. The predictive power of different anthropometric indicators for identification of pre-hypertension and hypertension patients was determined by Receiver Operating Characteristic curves (ROC). RESULTS: The median (range) age was 28.0 (18-40) years. The age standardised prevalences of pre-hypertension and hypertension were 37.2 (95% CI 34.0-40.6) and 8.5% (95%CI 6.7-10.8), respectively. Of hypertensive patients (n = 98), only 20 (20.4%) were aware of their condition. In multivariate analysis, increasing age, obesity and haemoglobin levels were significantly associated with pre-hypertension and hypertension. CONCLUSION: Despite a low prevalence of hypertension, over one third of the women had pre-hypertension. This poses a great challenge ahead as pre-hypertensive women may progress into hypertension as they grow older without appropriate interventions. Obesity was the single most important modifiable risk factor for pre-hypertension and hypertension. PMID- 30280464 TI - Angiographic and clinical outcomes of antegrade versus retrograde techniques for chronic total occlusion revascularizations: Insights from the PRISON IV trial. AB - OBJECTIVES: Available data indicate mixed outcomes after using retrograde techniques for chronic total occlusion(CTO) recanalization, with generally higher need for repeat revascularization. Aim of this study is to analyze the angiographic and clinical outcome of patients treated with retrograde techniques in the PRISON-IV trial. METHODS AND RESULTS: This is a post-hoc sub-analysis from the randomized PRISON-IV trial. Briefly, 330 patients with a successfully recanalized CTO lesion were randomized 1:1 to receive either hybrid-SES or EES. The hybrid-SES failed to reach the non-inferiority primary endpoint of in-segment late lumen loss at 9-month angiography follow-up. In the present analysis, we divided the population according to the first technical approach, namely antegrade (n = 285) or retrograde approach (n = 45). Demographic characteristics were similar between the two groups, while angiographic features disclosed higher CTO lesion complexity in the group treated with retrograde techniques (J-CTO score: 1.8 +/- 1.1 vs 2.6 +/- 1.1, respectively, P < 0.001), with longer occlusions (17.6 +/- 10 mm vs 28.8 +/- 18.7 mm, P < 0.001) and longer stented segment (48.9 +/- 24.4 mm vs 73.1 +/- 33.2 mm, P < 0.001). Quantitative coronary analysis disclosed similar results at follow-up angiography, with a non significantly higher in-stent late-lumen loss in the retrograde group (0.08 +/- 0.52 mm vs 0.18 +/- 0.56 mm, P = 0.32). Clinical follow-up at 12-months showed similar outcome, with a non-significantly higher target-lesions revascularization rate in the retrograde group (6% vs 11.1% respectively, P = 0.2). Significant improvements in angina functional class were observed in both groups. CONCLUSIONS: The present analysis supports the benefits of retrograde techniques in CTO revascularization, with non-significant differences in angiographic and clinical outcomes at late follow-up. PMID- 30280463 TI - Vitamin D insufficiency predicts mortality among older men, but not women: A nationwide retrospective cohort from Thailand. AB - AIM: Previous studies on the association between low vitamin D level and increased mortality mainly came from high-income countries. The primary objective of the present study was to examine the effect of sex on the association between 25-hydroxyvitamin D2 and D3 and mortality among community-dwelling older people in Thailand. METHODS: A cohort of individuals aged >=60 years from the Thai 4th National Health Examination Survey carried out in 2008 were followed and linked to a vital registry in 2015. Data regarding comorbid diseases, physical activity and serum vitamin D were obtained at the baseline assessment. Factors associated with all-cause mortality were determined using Cox proportional hazards models. RESULTS: A total of 1268 participants with a median age of 74.0 years (interquartile range 67.0-81.0) were included. The prevalence of vitamin D insufficiency was 24.5% and 43.9% in men and women, respectively. Vitamin D insufficiency was significantly associated with all-cause mortality only among men (adjusted HR 1.77, 95% CI 1.25-2.51), but not women. Analysis of 25 hydroxyvitamin D3 divided into tertiles also showed an association with an adjusted HR of 1.83 (95% CI 1.23-2.72) for the lowest tertile in men. Diabetes was an effect modifier for low serum vitamin D and male sex, with HR 3.34 (95% CI 1.76-6.33, P < 0.001) in diabetic men with vitamin D insufficiency. CONCLUSIONS: Low serum vitamin D is an independent risk factor for increased mortality in community-dwelling Thai older men. Further randomized controlled study to investigate the benefit of vitamin D3 supplementation in older persons, particularly men, is warranted. Geriatr Gerontol Int 2018; **: **-**. PMID- 30280465 TI - Association between diabetic eye disease and other complications of diabetes: Implications for care. A systematic review. AB - The aim of this systematic review was to examine the associations between diabetic retinopathy (DR) and the common micro- and macrovascular complications of diabetes mellitus, and how these could potentially affect clinical practice. A structured search of the PubMed database identified studies of patients with diabetes that assessed the presence or development of DR in conjunction with other vascular complications of diabetes. From 70 included studies, we found that DR is consistently associated with other complications of diabetes, with the severity of DR linked to a higher risk of the presence of, or of developing, other micro- and macrovascular complications. In particular, DR increases the likelihood of having or developing nephropathy and is also a strong predictor of stroke and cardiovascular disease, and progression of DR significantly increases this risk. Proliferative DR is a strong risk factor for peripheral arterial disease, which carries a risk of lower extremity ulceration and amputation. Additionally, our findings suggest that a patient with DR has an overall worse prognosis than a patient without DR. In conclusion, this analysis highlights the need for a coordinated and collaborative approach to patient management. Given the widespread use of DR screening programmes that can be performed outside of an ophthalmology office, and the overall cost-effectiveness of DR screening, the presence and severity of DR can be a means of identifying patients at increased risk for micro- and macrovascular complications, enabling earlier detection, referral and intervention with the aim of reducing morbidity and mortality among patients with diabetes. Healthcare professionals involved in the management of diabetes should encourage regular DR screening. PMID- 30280466 TI - Real-world comparison of the new 34 mm self-expandable transcatheter aortic prosthesis Evolut R to its 31 mm core valve predecessor. AB - OBJECTIVES: The aim of the present study was to compare the incidence of periprocedural complications and short-term outcomes between the second generation recapturable 34 mm Evolut-R and its first-generation 31 mm predecessor. BACKGROUND: Although already in extensive clinical use in real world patients, the periprocedural complications and clinical outcomes of the new 34 mm device have not been investigated yet. METHODS: Consecutive patients who had undergone transcatheter aortic valve implantation in two centers with either a 31 mm CoreValve or a 34 mm Evolut-R device were retrospectively studied. Periprocedural complications of malpositioning, valve-in-valve implantation, conversion to full sternotomy or percutaneous coronary intervention and vascular complications were compared between the two groups. Short-term outcomes at discharge were compared using Valve Academic Research Consortium (VARC-2) criteria. RESULTS: The study group included 106 patients (35 Evolut-R 34 mm; 71 CoreValve 31 mm). Significantly lower rates of valve-in-valve implantation were demonstrated for the 34 mm group compared to the first-generation device (0% vs. 11.9%, respectively, P = 0.036). All other periprocedural complications were similar between groups. At discharge, the rates of new pacemaker implantation (5.7% vs. 26.8%, P = 0.037) and bleeding complications (2.9% vs. 19.6%, P = 0.025) were statistically significantly lower among the 34 mm group. With regards to VARC-2 defined combined endpoints, rates of early safety were significantly improved among the 34 mm group compared to 31 mm group (0% vs. 27.9%, respectively, P = 0.004). CONCLUSIONS: The recently introduced 34 mm Evolut-R seems to demonstrate an improved safety profile, as evidenced by the reduced bleeding rates, lower rates of valve-in-valve implantation and lower PPM rates compared to its 31 mm predecessor. PMID- 30280467 TI - Awareness of oral medicine among medical practitioners, evidence of the unbridged interdisciplinary gap. AB - RATIONALE, AIMS, AND OBJECTIVES: Inadequate awareness of oral health and related disciplines appears to be common among medical practitioners. This study was designed to evaluate the awareness of oral medicine (OM) specialty and its scope of practice among Jordanian medical practitioners and to outline potential strategies for improvement where appropriate. METHOD: A specially designed questionnaire was electronically distributed to Jordanian medical practitioners and thereafter via personal interviews to improve the response rate. The questionnaire comprised nine questions and covered demographical details and characteristics of participants, in addition to their awareness of OM and agreement to refer a group of common oral and dental conditions to OM specialists. Pearson Chi-square tests were used to examine the significance of association between the variables of respondents and awareness of OM. Significance level was set at P values < 0.05. RESULTS: A total of 1492 respondents completed the questionnaire, of which 779 (52.2%) were aware of OM as an independent specialty. Age group, higher degrees in medicine, country of graduation, and the specialty type were significant determinants of OM awareness level. Oral ulceration and other mucosal pathology, including fungal infections, were the most likely conditions to be referred to OM specialists while participants had apparent problems separating the scope of practice of OM from other dental disciplines. CONCLUSION: This study provides evidence on the profound interdisciplinary gap between medicine and dentistry and highlights the importance of more focused education and training in oral health-related disciplines to be provided to clinicians and medical trainees as described. PMID- 30280468 TI - The efficacy of non-assisted reproductive technology treatment might be limited in infertile patients with advanced endometriosis in their 30s. AB - AIM: To determine the efficacious treatment for infertile couples, we assessed the impact of infertility factors including endometriosis on assisted reproductive technology (ART) and non-ART treatment, and the effect of age in infertility treatment outcomes was also investigated. METHODS: The medical records of 1864 females, infertile patients from January 2000 to December 2015 at our hospital, were retrospectively reviewed under the approval of the Institutional Review Board. We extracted 10 representative factors and calculated the cumulative live birth rate (CLBR) in these patients. Multivariate analysis of ART and non-ART treatment was performed to assess the impact of infertility factors, and the age-related decline in cumulative live birth rate was calculated by creating eight age-stratified subgroups. RESULTS: In total, 21.9% and 49.4% of the patients conceived after being treated with non-ART and ART, respectively. Multivariate analysis revealed that age > 35, advanced endometriosis defined by the revised American Society for Reproductive Medicine classification system stages III to IV, and the past history or current presence of uterine fibroid had significantly negative impact on the outcome of non-ART. Age stratification revealed that advanced endometriosis adversely affected the outcome of non-ART, especially for patients in their 30s. Assisted reproductive technology treatment for patients with advanced endometriosis was shown to be efficacious because the negative impact had been diminished. CONCLUSION: Considering that non-ART treatment had limited role in patients with advanced endometriosis, prompt initiation of ART in these patients aged as young as 30 years can be recommended to achieve conception. PMID- 30280469 TI - Role of contractile reserve as a predictor of mortality in low-flow, low-gradient severe aortic stenosis following transcatheter aortic valve replacement. AB - OBJECTIVES: The aim of this study was to determine the prognostic value of contractile reserve (CR) at baseline in patients with low-flow, low-gradient severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND: Patients with severe AS, left ventricular dysfunction, and low transaortic gradient are at high risk for mortality during surgical aortic valve replacement (SAVR). Furthermore, patients without CR have been shown to have perioperative mortality comparable to that of patients treated medically for severe AS. METHODS: We retrospectively analyzed patients who underwent TAVR with a diagnosis of low-gradient severe AS (mean transvalvular aortic gradient < 40 mmHg, LVEF < 50%, and AVA <= 1.0 cm2 or AVAi <= 0.6 cm2 ) and who had a pre-TAVR dobutamine stress echocardiogram (DSE). Patients were stratified by the presence or absence of CR, defined as an increase in stroke volume >= 20% during DSE. RESULTS: From 2008 to 2016, 61 patients with low-gradient severe AS underwent TAVR and had pre-TAVR DSE. CR was present in 31 patients (51%) and absent in 30 (49%). There was no significant difference between the two groups in baseline demographics, medical history, access site, or types of valves. All-cause mortality was similar in both groups at 30 days (13% with CR vs 10% without CR, P = 1.00) and 1 year (29% with CR vs 33% without CR, HR 1.20, 95% CI 0.49-2.96, P = 0.69). CONCLUSION: In patients with low-flow, low-gradient severe AS undergoing TAVR, the presence or absence of CR does not predict all-cause mortality at 30 days or 1 year. PMID- 30280471 TI - Percutaneous closure of paravalvular leak after Cone repair for Ebstein's anomaly. AB - We report the use of an Amplatzer Vascular plug for percutaneous closure of a paravalvular leak after Cone repair in a 5-year-old boy with Ebstein's anomaly. A paravalvular leak of the tricuspid valve developed gradually after Cone repair surgery. The combination of fluoroscopy, transesophageal and transthoracic imaging during general anesthesia was necessary for correct and safe positioning of the device by percutaneous approach. The results were promising. PMID- 30280470 TI - A comparative study of ammonia transport across ruminal epithelia from Bos indicus crossbreds versus Bos taurus. AB - Absorption of ammonia from the rumen of cattle decreases nitrogen availability for fermentational protein synthesis, leading to increased competition of cattle with humans for protein and enhancing the release of toxic nitrogenous compounds into the environment. Given that differences in feeding and breeding might induce differences in ruminal ammonia transport, we compared electrophysiological, histological, and molecular biological characteristics of ruminal epithelia of Bos indicus crossbreds (Sahiwal-Mix, SWM) with those of Bos taurus (Holstein Friesian, HF). As in HF, the stratified cornified epithelium of SWM expressed claudin 1 and 4. Measurements of ammonia flux (HF) and serosal pH (both breeds) suggested that at a mucosal pH of 6.4, net transport primarily occurred as NH4 + . As shown previously for HF, NH4 + induced a concentration-dependent rise in short circuit current (Isc ) in SWM that could be further stimulated by the TRP channel agonist menthol. Relative mRNA expression levels for TRPV3, TRPV4, TRPM6, and TRPM7 were significantly lower in SWM than in HF, with TRPA1 expression near the limit of detection. We conclude that uptake of ammonia from the rumen of both breeds occurs electrogenically as NH4 + with functional and molecular biological evidence pointing towards involvement of TRPV3 and TRPV4. PMID- 30280472 TI - Predictors and etiologies of 30-day readmissions in patients with non-ST elevation acute coronary syndrome. AB - BACKGROUND: Despite improvements in acute care and survival after non-ST elevation acute coronary syndrome (NSTE-ACS) hospitalization, early readmissions remain common, and have significant clinical and financial impact. OBJECTIVES: Determine the predictors and etiologies of 30-day readmissions in NSTE-ACS. METHOD: The study cohort was derived from the National Readmission Database 2014 identifying patients with a primary diagnosis of NSTE-ACS using ICD9 code. RESULTS: We identified a total of 300,269 patients admitted with NSTE-ACS; 13.4% were readmitted within 30-day. The most common cause of readmission was heart failure (HF) (15.6%), followed by a recurrent myocardial infarction (MI) (10%). Predictors of increased readmissions were age >= 75 years (OR: 1.34, 95% CI: 1.30 1.39), female gender (OR 1.12, 95% CI 1.09-1.16), a Charlson Comorbidity Index (CCI) >3 (OR 2.11, 95% CI: 2.04-2.18), ESRD (OR 2.01, 95% CI 1.89-2.14), CKD (OR: 1.58, 95% CI: 1.51-1.64), length of stay >=5 days (OR: 1.51, 95% CI 1.46-1.56) and adverse events during the index admission such as AKI (OR:1.31, 95% CI: 1.25 1.36), major bleeding (OR:1.20, 95% CI: 1.12-1.24); whereas admission to a teaching hospital (OR 0.92, 95% CI 0.89-0.95) and PCI (OR 0.70, 95% CI 0.67-0.72) were associated with less likelihood of 30-day readmission. CONCLUSION: Readmission rate at 30-days is high among NSTE-ACS patients and the most common readmission etiologies are HF and recurrent MI. A CCI more than 3 and ESRD were the most significant predictors for readmission; patients undergoing PCI had less odds of readmission. PMID- 30280473 TI - Skin surface lipid differences in sensitive skin caused by psychological stress and distinguished by support vector machine. AB - BACKGROUND: Sensitive skin refers to skin that tends to be highly responsive to stimuli such as physical, chemical, and psychological. Psychological factors play an important role in the pathology of sensitive skin. OBJECTIVE: This study investigated lipid difference between sensitive skin caused by psychological stress and normal skin, followed by construction of a support vector machine (SVM). METHODS: A noninvasive method was used to collect lipid samples from the skin surface. Ultra-performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC-Q-TOF-MS) technique and partial least squares discriminant analysis (PLS-DA) was used to screen for differential lipids. A correlation analysis was performed on differential lipids, and a support vector model was established based on the differential lipids. RESULTS: Twelve differential lipids were obtained, and the most differentiating species were triacylglycerols (TGs), followed by monounsaturated fatty acids (MUFAs), saturated fatty acids (SFAs), diacylglycerols (DGs), and 6-hydroxysphingosine levels. Triglyceride, SFA, and MUFA species showed a high correlation, and the support vector machine (SVM) differentiation model based on differential lipids had a 100% accuracy rate. CONCLUSION: Psychological stress may cause damage to the permeability and antimicrobial barriers of the skin, thereby resulting in sensitive skin. Differentiation models based on SVMs have good prospects for distinguishing sensitive skin caused by psychological stress. PMID- 30280474 TI - Low-fluence Q-switched Nd:YAG laser for the treatment of melasma in Asian patients. AB - BACKGROUND: Melasma is a common acquired facial pigmentary disorder that is resistant to various modalities of treatment. Recently, the low-fluence 1064-nm Q switched neodymium-doped yttrium aluminum garnet laser (QSNY) has emerged as the new gold standard of melasma treatment in Asia. OBJECTIVE: To evaluate the efficacy and safety of low-fluence 1064-nm QSNY in Asian patients with melasma. METHODS: Data of patients with melasma treated with low-fluence QSNY in the department of dermatology at the Korea University Anam Hospital were reviewed retrospectively. A 1064-nm QSNY with 8 mm spot size and fluence of 1.2-2.0 J/cm2 at 10 Hz was used. The results were evaluated using the modified Melasma Area and Severity Index (mMASI) score and the physician's global assessment (PGA). RESULTS: A total of 40 Korean patients with Fitzpatrick skin type III to IV were included. Patients were treated for a median of 10 sessions at a median of 1-week intervals. The mean mMASI score decreased by 54.23% from a baseline of 3.19 +/- 2.64 to 1.46 +/- 1.06 after treatment. On PGA, 1 out of 40 patients (2.5%) showed excellent improvement, 14 (35%) good, 15 (37.5%) fair, 6 (15%) poor, and 4 (10%) no improvement. However, two patients showed mottled hypopigmentation and rebound hyperpigmentation. CONCLUSION: Low-fluence 1064-nm QSNY appears to be a safe and effective treatment for Asian patients with melasma. PMID- 30280475 TI - Comparison of coronary revascularization appropriateness for non-acute coronary syndrome cases under the 2017 update vs the 2012 appropriate use criteria. AB - OBJECTIVES: To compare coronary revascularization appropriateness for non-acute coronary syndrome cases under the 2017 update vs the 2012 appropriate use criteria (AUC). BACKGROUND: In 2017, the 2012 AUC for coronary revascularization were updated. We examined how applying these new 2017 updates to our previous inappropriate cases would change their appropriateness. METHODS: We identified 50 cases of patients who underwent coronary revascularization for stable ischemic heart disease who were deemed inappropriate under the 2012 AUC. Two separate physicians reviewed the cases and applied a new AUC based on the 2017 AUC. Next, if there was a change, the reason was identified. RESULTS: Average age was 64, majority being male (29; 58%). Forty-two (84%) were asymptomatic upon presentation. Most cases (27, 54%) dealt with percutaneous coronary intervention (PCI) of the right coronary artery. After applying the 2017 AUC, 34 of the 50 inappropriate failures (68%) would be changed from "inappropriate" to "may be appropriate care." Of the 34 cases, 25 (73.5%) were changed due to the new AUC no longer expecting the patient to be on >=2 anti-angina medications prior to PCI. Of the 34 cases, eight (23.5%) were changed due to the new AUC expanding the use of non-invasive modalities. CONCLUSIONS: Applying the 2017 AUC led to a statistically higher number of cases being deemed "may be appropriate." The most common cause for the change included the change in requirement for anti-angina regimen and the expanded role of non-invasive modalities. PMID- 30280476 TI - Rate of major adverse renal or cardiac events with iohexol compared to other low osmolar contrast media during interventional cardiovascular procedures. AB - OBJECTIVE: This study assessed the rate of major adverse renal or cardiac events (MARCE) when iohexol is used during interventional cardiovascular procedures compared to other low osmolar contrast media (LOCMs). BACKGROUND: Interventional cardiovascular procedures are often essential for diagnosis and treatment, the risk of MARCE should be considered. METHODS: Data were derived from the Premier Hospital Database January 1, 2010 through September 30, 2015. Patient encounters with an inpatient primary interventional cardiovascular procedure with a single LOCM (iohexol, ioversol, ioxilan, ioxaglate, or iopamidol) were included. The primary outcome was a composite endpoint of MARCE, which included: renal failure with dialysis, acute kidney injury (AKI) with or without dialysis, contrast induced AKI, acute myocardial infarction, angina, stent occlusion/thrombosis, stroke, transient ischemic attack, or death. Multivariable regression analysis was performed using the hospital fixed-effects specification to assess the relationship between MARCE and iohexol compared to other LOCMs, while controlling for patient demographics, comorbid conditions and reason for hospitalization. As a sensitivity analysis, direct comparisons of iohexol were made to other LOCMs. RESULTS: A total of 458,091 inpatient encounters met inclusion criteria of which 26% used iohexol and 74% used other LOCMs. Results of multivariable modeling revealed no differences in MARCE rates between iohexol and other LOCMs. When direct comparisons of iohexol vs. ioversol and iopamidol were modeled, no differences in MARCE nor the renal component of MARCE were found. CONCLUSIONS: In this retrospective multicenter study, there were no differences in MARCE events with iohexol compared to other LOCMs during inpatient interventional cardiovascular procedures. PMID- 30280477 TI - Using the Value of Information to improve conservation decision making. AB - Conservation decisions are challenging, not only because they often involve difficult conflicts among outcomes that people value, but because our understanding of the natural world and our effects on it is fraught with uncertainty. Value of Information (VoI) methods provide an approach for understanding and managing uncertainty from the standpoint of the decision maker. These methods are commonly used in other fields (e.g. economics, public health) and are increasingly used in biodiversity conservation. This decision-analytical approach can identify the best management alternative to select where the effectiveness of interventions is uncertain, and can help to decide when to act and when to delay action until after further research. We review the use of VoI in the environmental domain, reflect on the need for greater uptake of VoI, particularly for strategic conservation planning, and suggest promising areas for new research. We also suggest common reporting standards as a means of increasing the leverage of this powerful tool. The environmental science, ecology and biodiversity categories of the Web of Knowledge were searched using the terms 'Value of Information,' 'Expected Value of Perfect Information,' and the abbreviation 'EVPI.' Google Scholar was searched with the same terms, and additionally the terms decision and biology, biodiversity conservation, fish, or ecology. We identified 1225 papers from these searches. Included studies were limited to those that showed an application of VoI in biodiversity conservation rather than simply describing the method. All examples of use of VOI were summarised regarding the application of VoI, the management objectives, the uncertainties, the models used, how the objectives were measured, and the type of VoI. While the use of VoI appears to be on the increase in biodiversity conservation, the reporting of results is highly variable, which can make it difficult to understand the decision context and which uncertainties were considered. Moreover, it was unclear if, and how, the papers informed management and policy interventions, which is why we suggest a range of reporting standards that would aid the use of VoI. The use of VoI in conservation settings is at an early stage. There are opportunities for broader applications, not only for species-focussed management problems, but also for setting local or global research priorities for biodiversity conservation, making funding decisions, or designing or improving protected area networks and management. The long-term benefits of applying VoI methods to biodiversity conservation include a more structured and decision-focused allocation of resources to research. PMID- 30280478 TI - Angiographic characteristics and long-term prognostic impact of coronary artery disease in survivors after sudden cardiac arrest with a non-diagnostic electrocardiogram. AB - OBJECTIVES: Our purpose was to describe the prevalence, distribution, extension, and prognostic value of coronary artery disease (CAD) in patients resuscitated from sudden cardiac arrest (SCA) with non-diagnostic electrocardiogram (ECG). BACKGROUND: The impact of CAD and the indication for cardiac catheterization (CC) in patients resuscitated from SCA with non-diagnostic ECG are uncertain. METHODS: We included prospectively and consecutively 545 patients resuscitated from SCA with at least one CC during hospitalization. From them, 203 patients with a non diagnostic ECG formed our study population. Patients were followed-up 5 years after discharge. RESULTS: Overall, 125 (61.6%) patients had significant CAD, and at least one acute culprit lesion was found in 25 (12.4%). Regarding the burden and complexity of CAD, 78 (38.4%) patients had a CAD Prognostic Index of 0 and a SYNTAX score of 0. There was higher 5-year mortality only in patients with very high burden of CAD: three vessels with severe stenosis (P = 0.015) and CAD Prognostic Index Score >= 56 (P < 0.001). Tertiles of SYNTAX score did not predict higher 5-year mortality. CONCLUSIONS: In survivors from SCA with a non diagnostic ECG, significant CAD is highly prevalent. SYNTAX score was not associated with a different long-term prognosis in this patient population. Patients with severe disease in the three main coronary vessels and patients with higher (>=56) CAD Prognostic Index Score had a worse long-term prognosis. PMID- 30280480 TI - Long-term outcome of brachytherapy treatment for coronary in-stent restenosis: Ten-year follow-up. AB - OBJECTIVES: The objective of this study was to determine the long-term major adverse cardiac events (MACE) in patients treated with intracoronary brachytherapy (ICBT) for coronary in-stent restenosis (ISR). BACKGROUND: ICBT was commonly used to treat coronary ISR prior to the availability of drug-eluting stents (DES). The long-term outcomes of ICBT for ISR remain unknown. METHODS: Six hundred and eighty consecutive patients who underwent ICBT treated for ISR between September 1998 and April 2005 were included in the study. Clinical and angiographic data were collected and the long-term MACE were measured for all cause death, myocardial infarction (MI), and target vessel revascularization (TVR) at 10-year follow-up. RESULTS: Patients were 63 +/- 11 years old (66% male). The majority of patients were treated with a bare metal stent 670/680 (99%) prior to ICBT. Significant baseline clinical findings include high incidence of smokers 479/680 (70%), hyperlipidemia 638/680 (94%), and multivessel disease 526/680 (77%). The majority of target lesions were diffuse 407/680 (60%), and either in the left anterior descending 258/680 (38%) or right coronary artery 215/680 (32%). At 10-year follow-up, the rate of death was 25%, MI was 22.4%, and TVR was 48%. CONCLUSION: MACE at 10-year follow-up following ICBT for ISR indicates steady rate of death and MI and declining rate of TVR after 5 years. PMID- 30280479 TI - Favorable neurological outcome after ischemic cerebrovascular events in patients treated with percutaneous left atrial appendage occlusion compared with warfarin. AB - OBJECTIVES: This study sought to investigate neurological disability after ischemic cerebrovascular events in patients treated with left atrial appendage (LAA) occlusion compared with those on warfarin. BACKGROUND: Prior studies demonstrated that cerebrovascular events after LAA occlusion in patients with nonvalvular atrial fibrillation (NVAF) is largely nondisabling. METHODS: From the 1,189 patients in the Korean LAA Occlusion and European Amplatzer Cardiac Plug Multi-Center Registry, 24 patients who experienced ischemic cerebrovascular events after LAA occlusion were enrolled. The neurological outcomes were compared with those in 68 patients who experienced an ischemic cerebrovascular event while on warfarin (Yonsei Stroke Registry). A modified Rankin scale (mRS) score of 3-6 categorized the cerebrovascular event as disabling. The mRS at discharge and at 3 and 12 months postcerebrovascular event in the two groups was compared. RESULTS: The percentages of disabling cerebrovascular events were 37.5% and 58.8% at discharge (P = 0.07), 20.8% and 42.6% at 3 months (P = 0.08), and 12.5% and 39.7% at 12 months (P = 0.02) in the LAA occlusion and warfarin groups, respectively. The mRS was significantly lower in the LAA occlusion group at discharge and at 3 months (P < 0.01) and 12 months (P < 0.01) postcerebrovascular event despite no significant difference in mRS before cerebrovascular events (P = 0.98). Patients in the LAA occlusion group demonstrated a significant reduction in mRS between discharge and 12 months (P < 0.01), unlike patients in the warfarin group (P = 0.10). CONCLUSIONS: Ischemic cerebrovascular events in patients who previously underwent percutaneous LAA occlusion for NVAF were more favorable than in patients on warfarin. PMID- 30280481 TI - Effect of percutaneous paravalvular leak closure on hemolysis. AB - OBJECTIVE: To study the effect of percutaneous paravalvular leak closure on hemolysis. BACKGROUND: Although transcatheter PVL closure reduces heart failure and mortality in symptomatic patients with paravalvular leaks (PVL), little is known about its effect on hemolysis. METHODS: We retrospectively analyzed patients undergoing transcatheter mitral or aortic PVL closure (January 2005 December 2016) at Mayo Clinic. Patients with anemia or abnormal hemolysis markers (LDH, haptoglobin) were included in the analysis. The primary outcome was defined as hemoglobin increase >= 1.5 mg/dL, decrease in LDH above median or improvement in haptoglobin. Univariate and multivariate binary logistic regression modeling were used to determine predictors of successful treatment of hemolysis. RESULTS: Final study population included 168 patients (130 [77%] mitral, 38 [23%] aortic PVL). Primary outcome occurred in 70 patients (42%). Hemoglobin increased by 1.74 +/- 1.69 mg/dL in patients who reached primary outcome. 57/168 (34%) patients required blood transfusion prior to PVL closure compared to 35/168 (21%) postprocedure. The mean reduction in LDH was 403 U/L. Multivariate regression showed that patients with mechanical valves were more likely to have successful outcome (P = 0.044). CONCLUSION: Percutaneous PVL closure is associated with modest improvement in hemolysis markers, increase in hemoglobin levels and reduction in blood transfusion requirements. This benefit is most significant in patients with mechanical valves. PMID- 30280482 TI - Prospective, large-scale multicenter trial for the use of drug-coated balloons in coronary lesions: The DCB-only All-Comers Registry. AB - OBJECTIVES: This prospective, observational all-comers registry assessed the safety and efficacy of a Drug Coated Balloon-only strategy (DCB-only) in patients with coronary lesions. BACKGROUND: Data regarding the performance of a DCB-only approach, especially in patients with previously untreated de-novo coronary artery disease (CAD), are still limited. METHODS: This study was conducted as an international, multicenter registry primarily enrolling patients with de-novo CAD. However, it was also possible to include patients with in-stent restenosis (ISR). The primary endpoint was the rate of clinically driven target lesion revascularization (TLR) after 9 months. RESULTS: A total of 1,025 patients with a mean age of 64.0 +/- 11.2 years were enrolled. The majority of treated lesions were de-novo (66.9%), followed by drug-eluting-stent ISR (DES-ISR; 22.6%) and bare-metal-stent ISR (BMS-ISR; 10.5%). The TLR rate was lower in the de-novo group (2.3%) when compared to BMS- (2.9%) and DES-ISR (5.8%) (P = 0.049). Regarding MACE, there was a trend toward fewer events in the de-novo group (5.6%) than in the BMS- (7.8%) and DES-ISR cohort (9.6%) (P = 0.131). Subgroup analyses revealed that lesion type (95% CI 1.127-6.587); P = 0.026) and additional stent implantation (95% CI 0.054-0.464; P = 0.001) were associated with higher TLR rates. CONCLUSIONS: Our results show that DCB-only angioplasty of de-novo coronary lesions is associated with low MACE and TLR rates. Thus, DCBs appear to be an attractive alternative for the interventional, stentless treatment of suitable de-novo coronary lesions. PMID- 30280483 TI - Effect of platelet-rich plasma on proliferation and migration in human dermal fibroblasts. AB - BACKGROUND: Platelet-rich plasma (PRP) is a blood fraction that contains high concentrations of several growth factors. PRP has been recently used in skin wound healing and rejuvenation. However, the precise molecular mechanisms underlying PRP-induced wound healing are unknown. AIMS: This study aimed to evaluate the effects of PRP on extracellular matrix remodeling, which requires the activation of dermal fibroblasts. METHODS: Cell proliferation and migration assay, enzyme-linked immunosorbent analysis, and Western blotting were performed on PRP-treated human skin fibroblasts. RESULTS: Platelet numbers were enhanced by 4.6-fold in PRP compared to that in whole blood. PRP stimulated the proliferation and migration of human dermal fibroblasts and increased the expression of human procollagen I alpha 1, elastin, MMP-1, and MMP-2 in human dermal fibroblasts. PRP treated human dermal fibroblasts also showed a dramatic reduction in the phosphorylation of c-Jun N-terminal kinase (JNK), whereas total JNK levels were not significantly reduced. CONCLUSIONS: Collectively, PRP induced increased expression of type I collagen, elastin, MMP-1, and MMP-2, thereby accelerating wound healing. Our findings reveal basic mechanisms underlying PRP-mediated tissue remodeling. Thus, these results could be exploited for clinical dermatology and skin rejuvenation. PMID- 30280484 TI - Effectiveness of short-pulse width Nd:YAG in laser hair reduction. AB - INTRODUCTION: Laser hair reduction (LHR) is a safe and effective way of reducing unwanted hairs over body. Long-pulse Nd:YAG laser has over the years, been proven to be particularly safe and effective in darker skin types. While conventionally, long-pulse Nd:YAG laser has been used, recently short-pulse width Nd:YAG laser of 0.6-1.6 ms which is 10-50 times less than the standard method (long-pulse) of Nd:YAG LHR, has become available. OBJECTIVES: To study the effectiveness of short pulse width Nd:YAG laser in LHR in Indian patients. MATERIAL AND METHODS: This was a prospective observational study conducted over a period of 1 year. Fifty female patients with fitzpatrick skin type 3-5 were included. Patients underwent four sessions of LHR, with an interval of 6 weeks and then follow up was done for 6 months after the last session. RESULTS: The mean age of patient was 29.92 years ranging from 17 to 48 years. After finishing four sessions of LHR procedure 58%, 34%, 6%, and 2% of the patients showed excellent, good, moderate, and poor improvement respectively. No complications were seen during the treatment and after follow-up. Statistical analysis by paired t test showed the results to be statistically significant. CONCLUSION: Hair reduction using unique short-pulse width Nd:YAG laser is easy to use, safe, and effective in Indian skin. PMID- 30280485 TI - The effect of NB-UVB on noncultured melanocyte and keratinocyte transplantation in treatment of generalized vitiligo using two different donor-to-recipient ratios. AB - BACKGROUND: The melanocyte and keratinocyte transplantation procedure (MKTP) is a safe and effective procedure in treatment of vitiligo. Major advantage of this technique is that a small area of donor skin is needed to cover a large recipient area. To date, there is no consensus on the optimal donor-to-recipient ratio (D/R) required to achieve acceptable repigmentation following melanocyte and keratinocyte transplantation procedure (MKTP) in generalized vitiligo. It has been postulated that the addition of post-transplantation phototherapy may enhance the results. This is first study to assess two different (D/R) ratios with or without adjuvant phototherapy. OBJECTIVE: To compare the repigmentation after MKTP using two different D/R ratios (1/3 and 1/10) with and without adjuvant phototherapy (NB-UVB). METHODS AND MATERIALS: In this non randomized prospective clinical trial, 42 patients with stable generalized vitiligo bilateral and symmetrical in distribution were included. Patients were divided into two groups, 21 patients with a total of 50 lesions were treated with MKTP using a D/R ratio of 1/3 (Group I; 3000 +/- 500 cell/mm2 ) and the other 21 patients with a total of 52 lesions were treated by MKTP using a D/R ratio of 1/10 (Group II; 1000 +/- 200 cell/mm2 ). To study the role of adjuvant phototherapy on repigmentation, lesions in each patient were divided into two subgroups (a and b): lesions in subgroups Ia and IIa (did not receive NB-UVB) and lesions in subgroups Ib and IIb (received adjuvant phototherapy NB-UVB, two sessions per week for 6 months). The overall grading of repigmentation used was excellent (90%-100% repigmentation), good (75%-89%), fair (50%-74%), and poor (<50%). Also, the percentage of VASI change and color matching were used to assess the results. The study design was approved by the ethical committee of the Faculty of Medicine, Assiut University (IRB attached). RESULTS: The mean percentage of repigmentation was significantly better in group I than group II cases in both areas with or without adjuvant NB-UVB. It was 86.00 +/- 16.21 and 87.62 +/- 11.66 in subgroups Ia and Ib, respectively, vs 24.14 +/- 18.08 and 29.98 +/- 16.34 in subgroups IIa and IIb, respectively (P value was 0.000). The percent of excellent response was significantly better in group I than group II. It was 60% and 64% in subgroups Ia and Ib, respectively, and 7.6 and 11.5 in subgroups IIa and IIb, respectively (P value was 0.000). The mean percentage of VASI change was significantly better in group I than group II cases in both areas. It was -90.74 +/- 15.84 and -92.06 +/- 11.86 in subgroups Ia and Ib, respectively, vs -23.10 +/- 32.85 and -26.03 +/- 35.15 in subgroups IIa and IIb, respectively (P value was 0.000). The percent of excellent color match was better in group I than group II. It was 84% and 88% in subgroups Ia and Ib, respectively, vs 34.6 in both subgroups IIa and IIb (P < 0.05). A higher density of epidermal cells was transplanted in the recipient area in group I (3000 +/- 500 cell/mm2 ) compared to group II (1000 +/- 200 cell/mm2 ). There were no statistically significant differences between subgroups (Ia vs Ib and IIa vs IIb) although percentage of repigmentation was slightly better in NB-UVB subgroups. CONCLUSIONS: The higher density of epidermal cells used in the suspension, the higher the percentage of repigmentation obtained. The usage of adjuvant phototherapy following NKMT can enhance the repigmentation response. PMID- 30280486 TI - Closure of mid-bore venotomies with VASCADE VCD after right and left heart catheterization. AB - OBJECTIVE: This single-center, retrospective analysis investigated the clinical outcomes of a novel vascular closure device (VASCADE, Cardiva Medical, Santa Clara, CA) for closure of 7F femoral venotomies. BACKGROUND: The VASCADE closure device has been widely used to close arteriotomy sites following femoral procedures; however, little data have been published regarding the device's utility in closure of venotomy sites after procedures such as right-heart catheterization. METHODS: This was a retrospective analysis of outcomes in 102 consecutive patients who underwent venous closure using the VASCADE device following diagnostic right and left-heart catheterization between March 2017 and May 2018. Patients' age, gender, valvular disease status, comorbidities, and periprocedural use of antiplatelet/anticoagulant therapy were analyzed. RESULTS: Closure was successful in 99% (101/102) of patients with respect to achieving the primary outcome of rapid hemostasis in <=3 min. There was one device failure requiring manual compression, with no further complications. There were no other related adverse events or complications through 30 days of follow-up. CONCLUSIONS: The VASCADE device achieved venous hemostasis in nearly all our patients. We believe devices for venous closure can aid in improving patient experience, safety, and efficiency during these procedures. PMID- 30280487 TI - Is a covered stent justifiable in the treatment of coronary artery perforation? An observational analysis of long-term results of two different covered stent types. AB - OBJECTIVES: In this retrospective observational study, we investigate outcome of patients treated with or without covered stent (CS) implantation in the management of coronary artery perforation (CAP) during coronary intervention. BACKGROUND: CSs have shown to be effective devices to achieve acute hemostasis in large CAP. However, doubts have been raised regarding their long-term outcome. METHODS: Data of 19 061 PCI procedures during a 10-year period were reviewed. Fifty-five cases of large CAP were withheld (Ellis type 2, 3 or cavity spilling). All medical and procedural records of these cases were retrospectively reviewed. RESULTS: Twenty-four (43.6%) patients were treated with CS implantation (15 polytetrafluoroethylene and 9 pericardium CSs). Twenty-six (47.3%) patients were managed without CS implantation, of whom five had unsuccessful delivery of a CS (stent delivery failure 17.2%). Although significantly more Ellis type-3 perforations were present in the CS group compared to the Non-CS group (75.0% vs 45.2%; P = 0.03), in-hospital mortality was not significantly different (8.3% vs 6.4%; [P = 0.79]). We observed a high rate of CS restenosis (29.2%) but a lower rate of CS thrombosis (4.2%). Despite these observations, 5-year MACE and all cause mortality were not significantly different between CS and Non-CS group (respectively, 58.8% vs 50.0% (P = 0.26) and 26.7% vs 13.3% (P = 0.36)). CONCLUSION: Although deliverability of CSs was not flawless and a high rate of CS restenosis appeared, short- and long-term outcome were comparable between patients treated with or without CS. Therefore, CSs are justifiable in the treatment of CAP. PMID- 30280488 TI - Truck-mounted area-wide applications of larvicides and adulticides for extended suppression of adult Aedes albopictus. AB - BACKGROUND: Given the lack of vaccines for most vector-borne diseases, vector control is often the primary option for disease control. Aedes albopictus are difficult to control because the immatures primarily develop in containers ubiquitous in residential properties. Conventional adulticide campaigns often result in brief, rebounding population declines, so incorporating new techniques into an integrated pest management program is imperative. We performed combined area-wide applications of the larvicides Bacillus thuringiensis var. israelensis and pyriproxyfen with the adulticide sumithrin and prallethrin to achieve extended suppression of Ae. albopictus populations in Trenton, NJ, USA. We deployed bioassay cups to assess the spatial penetration and efficacy of the applications. RESULTS: Inhibition of adult emergence was significantly higher in the treatment bioassay cups than in laboratory controls (z = 4.65, P < 0.0001) and field control bioassay cups (z = 8.93, P < 0.0001). We observed a lower trend in adult numbers following season-long combined application of pyriproxyfen and adulticide, with numbers of adult Ae. albopictus at the treatment site up to five times lower than at the control site. CONCLUSION: Pyriproxyfen is a powerful mosquito larvicide and pupacide with low mammalian toxicity that shows promise for area-wide vehicle-mounted (either ground or airborne) applications.

AB - INTRODUCTION: Reduction of radiation dosage in the pediatric cardiac catheterization laboratory (PCL) is important to reduce the risk of its stochastic effect in children with congenital heart disease. Lowering the frame rate would reduce radiation dosage possibly at the expense of image quality, potentially resulting in higher fluoroscopic time and procedural complication rate. METHODS: The data were retrospectively analyzed in three eras: era 1 (n = 234), cineangiography 30 frames/sec (f/s) and fluoroscopy 15 pulse/sec (p/s); era 2 (n = 381), cineangiography 30 f/s and fluoroscopy 6 p/s; and era 3 (n = 328), cineangiography 15 f/s and fluoroscopy 6 p/s. Also, three operators blinded to the frame rate setting evaluated cineangiography image quality. In this study, the impact of lowering the default frame rates on radiation dosage, fluoroscopic time, contrast volume, diagnostic image quality, and complication rates in the PCL was assessed. RESULTS: Overall radiation dosage progressively declined during these eras (70.0 vs 64.1 vs 36.6 uGym2 /kg, P < .001) without a difference in significant adverse event rates. There was no significant increase in either fluoroscopy time or contrast volume. There was no difference in the diagnostic image quality between cineangiography 30 and 15 f/s. Lowering the default frame/pulse rates of both fluoroscopy and cineangiography significantly decreased the overall radiation dosage in the PCL. Importantly, fluoroscopy time, contrast volume, and complication rates did not increase while maintaining diagnostic image quality. CONCLUSION: This quality improvement project proved successful in lowering radiation dosage without compromising the efficacy and safety of catheterizations. PMID- 30280490 TI - Correlation between retinal vein occlusion and cancer - a nationwide Danish cohort study. AB - PURPOSE: To explore the association between retinal vein occlusion (RVO) and incident cancer. METHODS: All Danish citizens with a first-time diagnosis of RVO and no previous diagnosis of cancer in the period from 1 January 2004 to 31 December 2014 were included. Five likewise cancer-free, age- and gender-matched controls were included in a control cohort. All were followed up for 5 years or until either first diagnosis of cancer or death. Proportional hazards models with adjustment for age, gender, year of diagnosis and covariates and death as competing risk were used to estimate the risk of being diagnosed with cancer. RESULTS: There were 7963 RVO patients without cancer at the time of diagnosis, and all could be matched to likewise cancer-free controls. Half of RVO patients were male, and the median age at RVO diagnosis was 70 years (61-79). The control cohort was similar in terms of gender and age. The risk of cancer within 1 year was 1.8 among RVO patients and 1.5 among controls. The crude risk of cancer was 1.22 (1.11;1.34) and upon full adjustment 1.15 (1.05;1.27). No time dependency was detected, and the types of cancer developed in RVO patients and controls were similar. CONCLUSION: Retinal vein occlusion (RVO) diagnosis is associated with an increased risk of being diagnosed with cancer. This risk is likely to reflect shared risk factors rather than a causal association. PMID- 30280492 TI - Is population-based screening for rheumatic heart disease precluded by the Cairo accord? Echocardiography...and beyond. AB - In the 2017, "Cairo Accord on Rheumatic Heart Disease-From Molecules to The Global Community" experts from endemic areas enumerated an approach to reduce the population burden of rheumatic heart disease. The 10 key recommendations include immediate logistical objectives as well as domains for further study. Echocardiographic population screening programs were relegated to research alone. Given the large body of supporting data, relegating echo screening to an investigational modality is an opportunity lost. PMID- 30280491 TI - Clinical and biological relevance of genetic alterations in pediatric T-cell acute lymphoblastic leukemia in Taiwan. AB - BACKGROUND: The leukemogenesis of T-cell acute lymphoblastic leukemia (T-ALL) involves multistep processes of genetic alterations. We aimed to determine the genetic alterations including common fusion transcripts, overexpression of T-cell transcription factor oncogenes, and deletion or mutation of targeted genes in pediatric T-ALL in Taiwan as well as their impact on outcomes in those treated with the Taiwan Pediatric Oncology Group-ALL-2002 protocol. PROCEDURE: Between 1995 and 2015, bone marrow samples obtained from 102 children aged <18 years consecutively diagnosed with T-ALL were examined. Thirty-two genetic alterations were examined by reverse transcription polymerase chain reaction (PCR) assays-PCR based assays-followed by direct sequencing, real time quantitative PCR with TaqMan assays, or multiplex ligase probe amplification. RESULTS: TAL1 overexpression, CDKN2A/2B deletions, and NOTCH1 mutation were the most frequent aberrations while none had NF1, SUZ12 deletion, JAK1 or JAK2 mutations, or NUP214 ABL1 fusion in our cohort. The most frequent cooperating occurrence of genetic alterations included CDKN2A/2B and MTAP, MTAP and CDKN2B, LEF1 and PTPN2, and HOX11L2 and PHF6 mutation/deletion. NOTCH1 mutations conferred a favorable overall survival, whereas SIL-TAL1 fusion, TAL overexpression, LEF1 deletion, and PHF6 deletion/mutation were associated with an inferior outcome. By multivariate analysis, PHF6 mutation/deletion was the only independent predictor for inferior overall survival. CONCLUSIONS: The present study showed that the frequencies of genetic alterations in Taiwanese children with T-ALL differed considerably from those reported in Western countries. PHF6 mutation/deletion was an independently adverse predictor. PMID- 30280493 TI - The association between complement factor H rs1061170 polymorphism and age related macular degeneration: a comprehensive meta-analysis stratified by stage of disease and ethnicity. AB - PURPOSE: The strength of association between complement factor H (CFH) rs1061170 polymorphism and age-related macular degeneration (AMD) differs between AMD subtypes and ethnicities. The main aim was to provide a systematic review and an updated meta-analysis stratified by stage of disease and ethnicity. METHODS: A literature search in the PubMed-Medline, EMBASE and Web of Science databases was conducted to identify epidemiological studies, published before September 2017, that included at least twp comparison groups (a control group with no signs of AMD and a case group of AMD patients). Genotype distribution, phenotype of the cases, ethnicity, mean age and gender ratio were collected. Odds ratios (ORs) and 95%CIs were estimated under the allelic, homozygous and heterozygous models. Sensitivity and subgroup analyses, by AMD subtype and ethnicity, were performed. RESULTS: The meta-analysis included data of 27 418 AMD patients and 32 843 controls from 76 studies. In Caucasians, the rs1061170 showed a significant association with early AMD (OR: 1.44; 95%CI 1.27-1.63), dry AMD (OR: 2.90; 95%CI 1.89-4.47) and wet AMD (OR: 2.46; 95%CI 2.15-2.83), under an allelic model. In Asians, the rs1061170 showed a significant association with advanced AMD (OR: 2.09; 95%CI 1.67-2.60), especially wet AMD (OR: 2.24; 95%CI 1.81-2.77). CONCLUSIONS: Our work provides a more comprehensive meta-analysis of studies investigating the effect of the CFH rs1061170 polymorphism on AMD risk. These findings not only improve the assessment of disease risk associated with the polymorphism, but also constitute a scientific background to be translated into clinical practice for AMD prevention. PMID- 30280494 TI - The first idea of IOL implantation. PMID- 30280495 TI - Determinants of mobile technology use and smartphone application interest in cancer patients. AB - BACKGROUND: Supportive care is a critical component of the treatment of cancer patients that is underutilized; patient lack of information about these services is an important barrier. Mobile technologies may be useful tools for delivering information, but cancer patient use of and interest in using them to learn about supportive care services have not been described. This study evaluates factors associated with cancer patient use of mobile technologies and interest in smartphone applications for information delivery about supportive care. METHODS: We conducted a cross-sectional survey among cancer patients from one urban academic hospital and 11 community hospitals. Patients self-reported use of mobile technologies and interest in smartphone applications. Multivariate logistic analysis was used to identify determinants of mobile technology use and smartphone interest. RESULTS: Among 631 participants, 466 (74%) reported regular use of mobile devices and 242 (39%) expressed an interest in supportive care information via smartphone applications. Patients under 45 were more likely to use a mobile device (Adjusted Odds Ratio [AOR] 6.8, 2.8-16.9 95% CI, P < 0.001) and were interested in smartphone applications for delivery of information (AOR 3.2, 1.8-5.9 95% CI, P < 0.001). Non-white patients had similar use of mobile technology compared to whites but reported greater interest in smartphone application-based information (AOR 3.4, 2.1-5.5 95% CI, P < 0.001). CONCLUSION: Many patients expressed interest in smartphone application-based information about supportive care services, especially those who are younger and non-white. Future studies should investigate the characteristics of patients and smartphones applications that will optimize information delivery through a mobile technology platform. PMID- 30280497 TI - A novel genomic approach to herbicide and herbicide mode of action discovery. AB - A herbicide with a new mode of action has not been commercialized for more than 30 years. A recent paper describes a novel genomic approach to herbicide and herbicide mode of action discovery. Analysis of a microbial gene cluster revealed that it encodes genes for both the biosynthetic pathway for production of the sesquiterpene aspterric acid and an aspterric acid-resistant form of dihydroxy acid dehydratase (DHAD), its target enzyme. Aspterric acid is weak compared with commercial synthetic herbicides, and whether DHAD is a good herbicide target is unclear from this study. Nevertheless, this genomic approach provides a novel strategy for the discovery of herbicides with new modes action. (c) 2018 Society of Chemical Industry.

AB - PURPOSE: To evaluate the prevalence of amblyopia and associated biometric factors in Danish children. METHODS: Determination of best-corrected visual acuity (BCVA) using ETDRS charts, non-cycloplegic subjective refractioning guided by automated refractometry, axial length and corneal curvature, fundus photography and optical coherence tomography (OCT) in 1335 children from the population-based Copenhagen Child Cohort 2000 (CCC2000) Eye Study. Birth data were obtained from the Danish Medical Birth Registry. RESULTS: The mean (+/-SD) age of children was 11.7 (+/ 0.4) years, and 47% were boys. Amblyopia prevalence was 1.5 (95% CL 0.8-2.2) %. Unilateral amblyopic eyes [BCVA < 80 ETDRS letters (0.8 snellen) and >=2 lines difference between the eyes] was 0.6 (95% CL 0.3-1.0) mm shorter, 1.34 (95% CL 0.30-2.37) D more hyperopic and had 0.79 (95% CL 0.14-1.44) D more astigmatism compared with fellow eyes. Compared with the right eyes of the non-amblyopic children, unilateral amblyopic eyes were 1.0 (95% CL 0.5-1.6) mm shorter, 2.48 (95% CL 1.11-3.86) D more hyperopic, 1.09 (95% CL 0.43-1.75) D more astigmatic and had a 47 (95% CL 13-81) MUm thicker subfoveal choroid. CONCLUSION: Amblyopia was found in 1.5% of Danish children born 22 years after the inception of the nationwide preschool visual screening programme. Amblyopia was associated with anisometropia, astigmatism, a thicker subfoveal choroid and a history of childhood strabismus. PMID- 30280499 TI - Application of an activity-based receptor bioassay to investigate the in vitro activity of selected indole- and indazole-3-carboxamide-based synthetic cannabinoids at CB1 and CB2 receptors. AB - Synthetic cannabinoids (SCs) are the most chemically diverse group of new psychoactive substances. This group has been associated with several intoxications, many with fatal outcomes. Although advancements have been achieved in pharmacology, metabolism, and detection of these compounds in recent years, these aspects are still unresolved for many SCs. The aim of this study was to investigate the in vitro potency of 14 indole- and indazole-based SCs by applying a stable CB1 or CB2 receptor activation assay and correlating the activity with their structure. The half-maximal effective concentration (EC50 ) of 5 chloropentyl, 5-bromopentyl, and 5-iodopentyl JWH-122 analogs varied from 74.1 to 283.7 nM for CB1 and 7.05 to 23.4 nM for CB2, where the addition of a chlorine atom enhanced the potency at CB1 compared with the bromo and iodo analogs. AM 2201 was the most active at CB1 within this naphthoylindole family, with an EC50 of 23.5 nM but with the lowest efficacy (Emax 98.8%). Within the indole-3 carboxamide derivatives, 5F-MDMB-PICA was the most active compound, with a CB1/CB2 EC50 of 3.26/0.87 nM and an Emax around three times higher than JWH-018. ADB-FUBINACA was the most potent tested SC overall, with a CB1/CB2 EC50 of 0.69/0.59 nM, and an Emax around 3-fold higher than that for JWH-018 at CB1. The data obtained in this study confirm how small differences in the structure of SCs might lead to large differences in their activity, especially at CB1, which may be correlated with differences in their toxic effects in humans. PMID- 30280500 TI - Optimization of a dispersive liquid-liquid microextraction method followed by UHPLC analysis for fluoxetine quantification in environmental water resources. AB - Fluoxetine is the most prescribed drug for treatment of depression. Recently, its presence in aquatic environment has been receiving a growing interest as several studies assessed its effects on aquatic fauna. Therefore, it's important to have an analytical method capable of monitoring these compounds at low concentrations. In this study, a new method was developed based on dispersive liquid-liquid microextraction to preconcentrate fluoxetine in a small volume of water sample (6 mL) before chromatographic analysis using ultra high performance liquid chromatography with fluorescence detection. Effect of composition and volume of extracting mixture, sample pH, vortexing time and salt addition were evaluated. Optimization of extraction conditions lead to an enrichment factor of 61 +/- 18. After extraction optimization, recovery percentages of fluoxetine spiked into different water matrices between 83-110% were obtained. For the optimized method, the calibration curve was obtained in the range of 160-2500 ng/L with a limit of detection of 98.9 ng/L and a limit of quantification of 329.8 ng/L. PMID- 30280501 TI - Miniphocibacter massiliensis gen. nov., sp. nov., a new species isolated from the human gut and its taxono-genomics description. AB - With the aim of describing the human microbiota by the means of culture methods, culturomics was developed in order to target previously un-isolated bacterial species and describe it via the taxono-genomics approach. While performing a descriptive study of the human gut microbiota of the pygmy people, strain Marseille-P4678T has been isolated from a stool sample of a healthy 39-year-old pygmy male. Cells of this strain were Gram-positive cocci, spore-forming, non motile, catalase-positive and oxidase-negative, and grow optimally at 37 degrees C under anaerobic conditions. Its 16S rRNA gene sequence exhibited 89.69% of sequence similarity with Parvimonas micra strain 3119BT (NR 036934.1), its phylogenetically closest species with standing in nomenclature. The genome of strain Marseille-P4678T is 2,083,161 long with 28.26 mol% of G+C content. Based on its phenotypic, biochemical, genotypic and proteomic profile, this bacterium was classified as a new bacterial genus and species Miniphocibacter massiliensis gen. nov., sp. nov. with the type strain Marseille-P4678T . PMID- 30280502 TI - Pulsatile Glenn as long-term palliation for single ventricle physiology patients. AB - OBJECTIVE: There are limited studies analyzing pulsatile Glenn as a long-term palliation strategy for single ventricle patients. This study sought to determine their outcomes at a single institution. DESIGN: A retrospective review was performed. SETTING: Study performed at a single pediatric hospital. PATIENTS: All single ventricle patients who underwent pulsatile Glenn from 1995 to 2016 were included. OUTCOME MEASURES: Pulsatile Glenn failure was defined as takedown, transplant, or death. Further palliation was defined as Fontan, 1.5, or biventricular repair. Risk factors were assessed by Cox multivariable competing risk analyses. RESULTS: Seventy-eight patients underwent pulsatile Glenn at age 9 months (interquartile range, 5-14). In total, 28% had heterotaxy, 18% had a genetic syndrome, and 24% had an abnormal inferior vena cava. There were 3 (4%) perioperative mortalities. Further palliation was performed in 41 (53%) patients with a median time-to-palliation of 4 years (interquartile range, 3-5). Pulsatile Glenn failure occurred in 10 (13%) patients with 8 total mortalities. Five- and 10-year transplant-free survival were 91% and 84%, respectively. At a median follow-up of 6 years (interquartile range, 2-8), 27 patients (35%) remained with PG (age 7 years [interquartile range, 3-11], oxygen saturation 83% +/- 4%). Preoperative moderate-severe atrioventricular valve regurgitation (AVVR) (hazard ratio 7.77; 95% confidence interval 1.80-33.43; P =.005) and higher pulmonary vascular resistance (hazard ratio 2.59; 95% confidence interval 1.08-6.15; P =.031) were predictors of pulsatile Glenn failure after adjusting for covariates. Reaching further palliation was less likely in patients with preoperative moderate-severe AVVR (hazard ratio 0.22, 95% confidence interval 0.08-0.59; P =.002). CONCLUSION: Pulsatile Glenn can be an effective tool to be used in challenging circumstances, these patients can have a favorable long-term prognosis without reducing their suitability for further palliation.

AB - A direct transformation of ortho-alkynylated aromatic vinyl ethers to 1 iodonaphthalenes and other iodo-heterocycles under mild Lewis acidic conditions in the presence of iodide as an external nucleophile is reported. The first example of an iodoannulation strategy using a nucleophilic source of iodine, coupled with good to excellent yields, exclusive alpha regioselectivity and a broad substrate scope makes this work an attractive avenue towards the construction of aromatic iodides. PMID- 30280504 TI - Laser pointer maculopathy - on the rise? AB - PURPOSE: To report symptoms and ocular pathology in 13 patients exposed to light from laser pointers. METHODS: We conducted a multi-centre consecutive case series from eight ophthalmology departments. RESULTS: Eleven boys aged 9-15 years and two girls aged 7 (sister of one of the aforementioned boys) and 12 years, respectively, were included. Laser wavelengths were 572 nm (green), 450 nm (blue), and red laser of unknown wavelength. Output powers were between 5 and 5000 mW. Evaluation included slit lamp examination, colour fundus photography (CFP), and optical coherence tomography (OCT). All subjects complained of unilateral vision loss. Initial visual acuities in exposed eyes ranged from 0.05 to 1.0 Snellen equivalent or better. Nine subjects showed pathology on CFP and OCT abnormalities. One subject had a macular hole, which closed after vitrectomy. Long-term visual acuity ranged from 0.3 to 1.0 Snellen equivalent or better. CONCLUSION: High-powered laser pointers have become readily available on the internet, and they have the potential to induce lasting visual loss. More than half of the published laser pointer maculopathy cases since the first incidence in 1999 have been published in 2014-2017. We suspect that incidence of exposure and subsequent visual loss is rising, and we encourage national legislators to regulate this market. PMID- 30280505 TI - Temporal and spatial expression of the Fox gene family in the Leech Helobdella austinensis. AB - The Forkhead box (Fox) gene family is an evolutionarily ancient gene family named after the Drosophila melanogaster forkhead gene (fkh). Fox genes are highly conserved transcription factors critical for embryogenesis and carcinogenesis. In the current study, we report a whole-genome survey of Fox genes and their expression patterns in the leech Helobdella austienesis. Phylogenetic analysis suggests that some Fox genes of leeches are correlated with other Lophotrochozoa and vertebrate Fox genes. Here we have performed semiquantitative reverse transcription polymerase chain reaction and whole-mount in situ hybridization of Fox genes throughout the embryonic development of H. austinensis. We found that each one of the leech Fox genes (FoxA1, FoxA3, FoxC, FoxL2, FoxO1, and FoxO2) is expressed in a specific set of cells or tissue type. From Stages 9-11, Hau-FoxA1 was expressed in the foregut of the anterior region, and Hau-FoxL2 was expressed in mesodermal muscle fiber. Hau-FoxA3 was temporally expressed in the ventral neuroectoderm. At Stage 11, Hau-FoxC was expressed in the foregut. Hau-FoxO genes have a ubiquitous expression. Our results provide more insight on the evolutionary linkage and role of the Fox gene function in Bilateria. PMID- 30280506 TI - Associations between muscle mass, physical activity and dietary behaviour in adolescents. AB - BACKGROUND AND OBJECTIVES: Investigations in older individuals suggest that adequate nutrition and physical activity are particularly important to skeletal muscle health; however, data in adolescents are scant and equivocal. The objective was to determine the associations among diet, physical activity and skeletal muscle mass in adolescents. METHODS: We assessed diet with four to seven 24-h recalls and physical activity by accelerometry in 640 adolescents. Using total body measures of fat-free soft tissue mass and fat mass assessed by dual energy X-ray absorptiometry, the skeletal muscle mass index (SMMI) was derived by adjusting fat-free soft tissue mass for fat mass in addition to height. RESULTS: Skeletal muscle mass index (SMMI) was negatively associated with consumption of sugar-sweetened beverages (standardized beta coefficient [beta] = -0.10, P = 0.001) and saturated fats (beta = -0.28, P < 0.001). SMMI was positively associated with physical activity (moderate + vigorous) (beta = 0.20, P < 0.001). In further analysis, we observed a significant interaction between physical activity and sugar-sweetened beverage intake on SMMI (P = 0.002). CONCLUSION: Our study in adolescence suggests that physical activity and consumption of both sugar-sweetened beverages and saturated fats are associated with skeletal muscle mass. More importantly, our findings suggest that sugar-sweetened beverage intake may attenuate the beneficial effects of physical activity on skeletal muscle mass. PMID- 30280507 TI - Alterations in cerebral blood flow in children with congestive heart failure due to ventricular septal defect. AB - OBJECTIVE: We aimed to investigate the effect of ventricular septal defect (VSD) and heart failure on cerebral blood flow (CBF) in children, whether heart failure treatment improves CBF, and if there is any relationship between CBF and serum N terminal pro-brain natriuretic peptide (NT-proBNP) level. METHOD: Forty children with VSD (13 with heart failure) aged between 1 and 36 months were studied. The control group comprised 25 healthy children in the same age group. Maximum, minimum, and mean blood flow velocities and pulsatility indices of the right and left middle cerebral arteries were assessed using transcranial Doppler ultrasonography. Measurements of CBF and serum NT-proBNP levels were repeated in patients with heart failure a month post-heart failure treatment initiation. The groups were also compared in terms of defect diameters, cardiac structural changes, left ventricular systolic function, and findings related to pulmonary hypertension determined by echocardiography. Correlations between echocardiographic measurements and CBF parameters were analyzed. RESULTS: Although no significant difference was found between patient and control groups for CBF, right and left maximum CBF velocities significantly increased posttreatment in patients with heart failure (P = .04 and P = .01, respectively). Serum NT-proBNP levels in children with VSD associated with heart failure were significantly higher than those in children with VSD alone (P = .04) or in healthy children (P < .001). NT-proBNP levels were negatively correlated with right and left maximum CBF velocities (r = -0.39, P = .013 and r = -0.32, P = .043, respectively). CONCLUSION: Although no significant difference was found in CBF velocity among the study groups, increase in the CBF velocity post heart failure treatment and negative correlations between CBF velocity and both the VSD diameter and NT-proBNP levels indicate that the hemodynamic status due to VSD associated with heart failure has an effect on CBF. PMID- 30280508 TI - Electrochemical transition-metal-catalyzed C-H bonds functionalization: electricity as clean surrogates of chemical oxidants. AB - Transition-metal-catalyzed C-H activation attracts tremendous attentions in organic synthetic community because it obviates pre-functionalization of substrates.[1] Significant advances have been dedicated in the past several decades. However, it should be notated that super stoichiometric chemical oxidants, such as copper- or silver-based metal oxidants, benzoquinones (BQ), organic peroxides, potassium persulfate (K2S2O8), hypervalent iodine molecular oxygen (O2) and so on that are required for most of the reactions.[2] The disadvantages associated with above mentioned chemical oxidants, e.g. organic and/or heavy metal pollution, toxicity, highly risk of explosibility, especially because of the large scale usage and high costs limit its application in industry.[3] Thus, development of environmentally benign and user-friendly C-H bonds activation protocols in the absence of chemical oxidants would be urgently desirable. Organic electrosynthesis witnesses the renaissance because of its inherent advantages and unique characters.[4] Many advancements of electrochemistry in organic synthesis[5] as well as in organometallics have been made.[6] Redox reactions involve electron transfer. Therefore, in principle, losing or obtaining electrons on the surface of electrodes can be treated as clean surrogates of chemical redox reagents and thus environmental pollution, high costs, notorious toxicity and high risk of explosibility could be significantly reduced and/or suppressed. The result is fundamentally in line with the purpose of green chemistry. However, successful examples utilizing electricity as the clean surrogates of oxidants in transition-metal-catalyzed C-H activation are very elusive.[6] In order to aid the reader to understand this area, we wish to summarize recent progress in this area until the end of September 2018 in the format of minireview which is built on different transition metals. PMID- 30280510 TI - Retinal oxygen saturation as a non-invasive estimate for mixed venous oxygen saturation and cardiac output. AB - PURPOSE: To investigate the correlation between retinal vessel oxygen saturation and mixed venous oxygen saturation (SvO2-mixed ) and cardiac output (CO). METHODS: Retinal arterial (SaO2-retinal ) and venous (SvO2-retinal ) oxygen saturation were measured non-invasively with dual-wavelength retinal oximetry in subjects receiving invasive measurements of SvO2-mixed and CO through right heart catheterization. Correlations were analysed using Spearman's rank correlation coefficients and linear regression models. RESULTS: Fourteen patients (median age 62.7 years, range: 21-77) were included in the analysis. When adjusted for age, SvO2-retinal showed a positive correlation with SvO2-mixed (beta = 0.80, p = 0.003). Retinal arteriovenous oxygen saturation difference was significantly correlated with the inverse of CO (Spearman's rho = 0.59, p = 0.026). CONCLUSION: This pilot study provides proof of concept for the use of retinal oximetry as a non-invasive tool to assess systemic cardiovascular function. PMID- 30280511 TI - Changes in cardiometabolic markers in children with Prader-Willi syndrome and nonsyndromic obesity following participation in a home-based physical activity intervention. AB - BACKGROUND: Physical activity is associated with improved cardiometabolic markers in children with nonsyndromic obesity (NSO). Prader-Willi Syndrome (PWS) is a neurodevelopmental disorder characterized by obesity. OBJECTIVE: To compare cardiometabolic changes in response to a home-based parent-facilitated physical activity intervention between children with PWS or with NSO. METHODS: Participants included 18 children with PWS (age = 10.5 +/- 0.7y; body fat = 44.6 +/- 2.0%) and 30 children with NSO (age = 9.7 +/- 0.2y; body fat = 44.8 +/- 1.2%). Active Play @ Home was a 24-week physical activity intervention curriculum containing playground-based and active video games completed 4 days per week. Pre and post-intervention measurements included physical activity, body composition, blood samples analysed for glucose, insulin, lipids and cytokines, and insulin resistance computed using the homeostatic model of assessment for insulin resistance (HOMA-IR). RESULTS: All children (n = 48) showed a significant decrease in Interleukin-8 (3.64 +/- 0.24 vs. 3.06 +/- 0.22 pg/mL). Children with obesity who did not gain or who lost body fat percentage (n = 18) demonstrated a significant decrease in HOMA-IR (3.17 +/- 0.39 vs. 2.72 +/- 0.34) and an increase in high-density lipoprotein (44.30 +/- 2.51 vs. 47.29 +/- 2.59 mg/dL). All other measurements showed no significant changes. CONCLUSIONS: The most favourable changes in cardiometabolic factors were observed in children with nonsyndromic obesity who demonstrated no gain or a decrease in body fat percentage. PMID- 30280509 TI - Timing for cranioplasty to improve neurological outcome: A systematic review. AB - INTRODUCTION: Cranioplasty is a surgical technique applied for the reconstruction of the skullcap removed during decompressive craniectomy (DC). Cranioplasty improves rehabilitation from a motor and cognitive perspective. However, it may increase the possibility of postoperative complications, such as seizures and infections. Timing of cranioplasty is therefore crucial even though literature is controversial. In this study, we compared motor and cognitive effects of early cranioplasty after DC and assess the optimal timing to perform it. METHODS: A literature research was conducted in PubMed, Web of Science, and Cochrane Library databases. We selected studies including at least one of the following test: Mini Mental State Examination, Rey Auditory Verbal Learning Test immediate and 30-min delayed recall, Digit Span Test, Glasgow Coma Scale, Glasgow Outcome Scale, Coma Recovery Scale-Revised, Level of Cognitive Functioning Scale, Functional Independence Measure, and Barthel Index. RESULTS: Six articles and two systematic reviews were included in the present study. Analysis of changes in pre- and postcranioplasty scores showed that an early procedure (within 90 days from decompressive craniectomy) is more effective in improving motor functions (standardized mean difference [SMD] = 0.51 [0.05; 0.97], p-value = 0.03), whereas an early procedure did not significantly improve neither MMSE score (SMD = 0.06 [ 0.49; 0.61], p-value = 0.83) nor memory functions (SMD = -0.63 [-0.97; -0.28], p value < 0.001). No statistical significance emerged when we compared studies according to the timing from DC. CONCLUSIONS: It is believed that cranioplasty performed from 3 to 6 months after DC may significantly improve both motor and cognitive recovery. PMID- 30280512 TI - Endoplasmic reticulum stress-induced accumulation of VAMP721/722 requires CALRETICULIN 1 and CALRETICULIN 2 in Arabidopsis. AB - Excessive demand for translation and protein folding in the endoplasmic reticulum (ER) can cause ER stress in plants. Here, we show that CALRETICULIN 1 (CRT1) and CRT2 are critical components in the accumulation of VESICLE-ASSOCIATED MEMBRANE PROTEIN 721 (VAMP721) and VAMP722 during ER stress responses. We show that CRT2 interacts with VAMP722 and that CRT1/2 post-translationally maintain elevated VAMP721/722 levels under ER stress. The greater growth inhibition in VAMP721/722 deficient plants, induced by tunicamycin, suggests that plants under ER stress maintain physiological homeostasis, at least in part, by regulating VAMP721/722 levels, as VAMP721/722 are known to participate in various biological processes. PMID- 30280513 TI - Impact of a 6-month family-based weight management programme on child food and activity behaviours: short-term and long-term outcomes of the PEACHTM intervention. AB - BACKGROUND: The PEACHTM randomized controlled trial measured changes to children's food and activity behaviours following participation in a weight management programme. We have previously reported a 10% reduction in body mass index z-score at intervention end (6-month post-baseline) that was maintained to 24 months with no further intervention for the full study sample. OBJECTIVES: The objective of the study is to report changes in food and activity outcomes in the full sample at (i) the end of the 6-month intervention and (ii) 24-month post baseline (18-month post-intervention). METHODS: Changes in dietary and activity outcomes were assessed over time (baseline: n = 169, 8.1 +/- 1.2 years, body mass index z-score 2.72 +/- 0.62). Dietary intake was assessed using the Child Dietary Questionnaire, and times spent active and sedentary were assessed using a study specific questionnaire. Linear mixed models were used. RESULTS: There were significant time effects for all Child Dietary Questionnaire scores and activity and sedentary behaviours in the expected direction. Significant sex effects were observed for fruit and vegetable and sweetened beverages scores and for time spent in small screen-based activity. CONCLUSIONS: This is one of few child weight management studies to report short-term and long-term behaviour outcomes. It demonstrates that an intervention promoting food and activity behaviours consistent with guidelines can achieve modest changes, mediating improvements in relative weight. PMID- 30280514 TI - Downregulated miR-144-3p contributes to progression of lung adenocarcinoma through elevating the expression of EZH2. AB - OBJECTIVES: The intention of our study was to investigate the relationship between miR-144-3p and EZH2 as well as the effects of their interaction on cell propagation and invasiveness in lung adenocarcinoma (LUAD). METHODS: The expression levels of miR-144-3p and EZH2 in LUAD tissues and normal tissues were determined by qRT-PCR. The dual-luciferase reporter assay was utilized to validate the targeting relationship between miR-144-3p and EZH2. MTT assay and colony formation assay were performed to evaluate the viability and propagation of LUAD cells, while the effects of miR-144-3p and EZH2 on LUAD cell invasiveness were confirmed by transwell assay. Protein expression levels of VEGFA, MMP2, and MMP9 were measured by Western blot. Furthermore, xenograft tumor models were established to verify the effects of miR-144-3p on tumor formation and EZH2, VEGFA, MMP2 and MMP9 expressions in vivo. RESULTS: miR-144-3P was downregulated in LUAD tissues, and overexpression of miR-144-3p inhibited propagation and invasiveness of LUAD cells. EZH2 was a target of miR-144-3p and was highly expressed in LUAD cells. Knockdown of EZH2 could suppress the propagation and invasion of LUAD cells. Increased miR-144-3p expression exerted an inhibitory effect on LUAD tumor formation in vivo. CONCLUSION: Overexpression of miR-144-3p impeded the propagation and invasiveness of LUAD cells by targeting EZH2. PMID- 30280515 TI - Evaluation of tear meniscus by optical coherence tomography after different sodium hyaluronate eyedrops instillation. AB - PURPOSE: To evaluate changes in tear meniscus dynamics using optical coherence tomography (OCT) after the instillation of different concentrations of sodium hyaluronate (SH) ophthalmic solutions. METHODS: An experimental, double-masked, randomized study was performed. Twenty-three healthy subjects (16 women and seven men; mean age 23.57 +/- 2.56 years) participated in this study. About 35 MUl of 0.1%, 0.2%, 0.3% SH ophthalmic solutions and saline solution was instilled in a randomly assigned eye. Tear meniscus measurements (height, depth and turbidity) were taken with OCT at 30 seconds and 1, 3, 5, 10 and 20 min after instillation. Subsequently, the Schirmer test and tear break-up time (TBUT) were evaluated. RESULTS: Tear meniscus depth and tear meniscus height showed a significant increase with all solutions compared to basal values: up to 3 min for 0.1% SH, up to 5 min for 0.2% and up to 10 min for 0.3% SH ophthalmic solution. Tear meniscus turbidity was also increased at 30 seconds for 0.1%, 0.2% and 0.3% SH artificial tears (p < 0.05). This increase remained significant for up to 1 min for 0.2% and 0.3% SH solutions (p < 0.05). After 5 min of saline and 0.1% SH instillation, the turbidity was lower than basal values (p < 0.05). There was a significant increase in the TBUT for all solutions after instillation (p < 0.05). No differences between the Schirmer pre- and postinstillation were found (p > 0.05). Finally, the comfort was significantly improved for all ophthalmic solutions (p < 0.05). CONCLUSION: Sodium hyaluronate (SH) ophthalmic solutions increase residence time in healthy subjects and are positively correlated with its concentration and therefore the viscosity. PMID- 30280516 TI - The vitreopapillary interface in healthy and glaucoma: posterior vitreous detachment in the vitreopapillary interface study. AB - PURPOSE: To investigate the vitreopapillary interface (VPI) in health and glaucoma according to the different stages of posterior vitreous detachment (PVD) formation. METHODS: Prospective single centre study including healthy subjects and glaucoma patients. PVD staging was performed with spectral domain optical coherence tomography. Gender, age, lens status and refractive error were assessed in both groups. Glaucoma patients additionally had a comprehensive ophthalmological investigation including intraocular pressure measurement, visual field testing and confocal imaging of the optic nerve head. RESULTS: Data on 523 subjects (993 eyes) were included from the VPI study (clinicaltrials.gov NCT02290795) database (493 eyes of 258 healthy subjects and 500 eyes of 265 glaucoma patients). Healthy subjects were significantly younger than primary open angle glaucoma patients (59.7 +/- 14.81 versus 70.0 +/- 10.78 years, p < 0.001), but were otherwise matched for refractive error and gender. Significantly more glaucomatous eyes were pseudophakic (26.6% versus 5.1%). Including only phakic nonoperated eyes from subjects between 50 and 80 years old decreased the age difference between healthy and open angle glaucoma (64.1 +/- 8.0 versus 65.9 +/- 6.7 years, p = 0.051). Comparing these subgroups rendered similar average ages for PVD stages 0 and 4, in contrast to the significant older age for the glaucoma subgroup in stage 1 (64.1 +/- 6.01 versus 61.4 +/- 8.38 years, p < 0.001) and a trend towards significance in stage 3 (70.8 +/- 69.8 versus 67.5 +/- 5.92 years, p = 0.051). CONCLUSION: The VPI study is a large clinical trial investigating the VPI in health and glaucoma. A subset of glaucoma patients seems to experience stages 1-3 of PVD formation at older age compared to healthy subjects. PMID- 30280517 TI - Proteomic analysis of posterior capsular plaques in congenital unilateral cataract. AB - PURPOSE: To obtain insights on the protein composition of posterior capsular plaques (PCP) in congenital unilateral cataract with anterior vitreolenticular interface dysgenesis (AVLID). METHODS: Posterior capsular plaque's were collected during surgery in children presenting with congenital unilateral cataract. Surgeries were analysed focusing on the type of cataract, the integrity of the posterior capsule after peeling the PCP and the presence of vitreolenticular adherences when performing primary posterior capsulorhexis. Proteome analysis was performed on the collected PCPs. RESULTS: Posterior capsular plaques collection and proteome analysis were feasible from four children presenting with unilateral idiopathic congenital cataract and AVLID. A large portion of the proteins found in the PCPs was similar to the proteins known to be present in lens epithelial cells and fibres. Proteins like vimentin, fibronectin, collagen type I, collagen type VI and lumican were also found, which typically are present in mesenchymal tissue but not in lens tissue or capsule. CONCLUSION: Posterior capsular plaques in cases of unilateral idiopathic congenital cataract of the AVLID type present a protein composition of mainly proteins found in lens epithelial cells and fibres. Some proteins however are a specific for lens tissue and are typically seen in mesenchymal tissue. PMID- 30280518 TI - Influence of CTNNB1 rs2953 polymorphism on schizophrenia susceptibility in Chinese Han population through modifying miR-485 binding to CTNNB1. AB - Schizophrenia (SCZ) and bipolar disorder (BD) are two major neuropsychiatric diseases that are the most substantial causes of disability and mortality worldwide. CTNNB1 encodes beta-catenin, an important protein in canonical Wnt signaling. We aimed to investigate the association between the rs2953 of CTNNB1 and the risk of SCZ and BD and to further explore the function of rs2953. A total of 1658 samples (548 SCZ cases, 512 BD cases, and 598 controls) were examined in terms of the genotype of CTNNB1 rs2953. The mRNA expression level of CTNNB1 significantly increased in the SCZ and BD groups compared with that in the control group. Significant association remained between CTNNB1 3'-untranslated region (UTR) variant rs2953 and SCZ susceptibility (additive and dominant model) after gender and age were adjusted. rs2953 disrupted the binding of CTNNB1 and miR-485. miR-485 significantly suppressed the luciferase activity of CTNNB1-T vector by binding to the CTNNB1 3'-UTR containing the T allele of rs2953. The mRNA expression of CTNNB1 can be used as a biomarker for the diagnosis of SCZ and BD. The 3'-UTR variant rs2953 in CTNNB1 influences the risk of SCZ in the Han Chinese population and modifies the binding of miR-485 to CTNNB1. PMID- 30280519 TI - Evaluation of vision screening in five- to eight-year-old children living in Region Vastra Gotaland, Sweden - a prospective multicentre study. AB - PURPOSE: To evaluate the current vision screening criteria regarding amblyopia and refractive errors, with emphasis on screening limits and retesting, in Region Vastra Gotaland (VGR), Sweden. Visual acuity (VA) screening is performed by nurses at primary healthcare centres (PHCs) in 4-year-old children and at school in 6- or 7-year-old children. Children with VA <0.65 (>0.19 logMAR) at either eye are referred. If VA is 0.65 in one or both eyes, a retest is performed by nurses at PHCs and schools, the children are then referred if VA is <0.8 (>0.10 logMAR). METHODS: We included all children aged >=5 and <8 years referred between October 2014 and June 2015 from PHCs and schools to the four eye clinics in VGR, with VA >=0.65 in one or both eyes. At the eye clinic, children underwent assessment of VA, refraction in cycloplegia, eye motility, cover test, stereo test and a slit lamp examination. RESULTS: Among the 259/295 children (139 female) participating, median age was 5.7 years (5.0-7.8 years) at referral. Glasses were prescribed due to subnormal VA with refractive errors in 20% of the children, 22% displayed heterophoria, none had heterotropia and one younger child had amblyopia. Accurate retesting gave fewer false-positive referrals. CONCLUSION: Our results showed that a vision screening referral cut-off limit of VA <0.65 would leave undetected refractive errors. Residual amblyopia was uncommon. Accurate referral criteria, retesting and training of those performing the screening as well as re-evaluation of the screening programme are all important. PMID- 30280521 TI - Subcutaneous Leydig Stem Cell Autograft: A Promising Strategy to Increase Serum Testosterone. AB - Exogenous testosterone therapy can be used to treat testosterone deficiency; however, it has several adverse effects including infertility due to negative feedback on the hypothalamic-pituitary--gonadal (HPG) axis. Leydig stem cell (LSC) transplantation could provide a new strategy for treating testosterone deficiency, but clinical translatability of injecting stem cells inside the testis is not feasible. Here, we explore the feasibility of subcutaneously autografting LSCs in combination with Sertoli and myoid cells to increase testosterone. We also studied whether the grafted LSCs can be regulated by the HPG axis and the molecular mechanism behind this regulation. LSCs were isolated from the testes of 12-week-old C57BL/6 mice, and subcutaneously autografted in combination with Sertoli cells and myoid cells. We found that LSCs alone were incapable of self-renewal and differentiation. However, in combination with Sertoli cells and myoid cells, LSCs underwent self-renewal as well as differentiation into mature Leydig cells. As a result, the recipient mice that received the LSC autograft showed testosterone production with preserved luteinizing hormone. We found that testosterone production from the autograft was regulated by hedgehog (HH) signaling. Gain of function and loss of function study confirmed that Desert HH (DHH) agonist increased and DHH antagonist decreased testosterone production from autograft. This study is the first to demonstrate that LSCs, when autografted subcutaneously in combination with Sertoli cells and myoid cells, can increase testosterone production. Therefore, LSC autograft may provide a new treatment for testosterone deficiency while simultaneously preserving the HPG axis. Stem Cells Translational Medicine 2018.

AB - INTRODUCTION: Ascertaining putative sociodemographic and clinical causes for death by probable suicide can potentially help implement region-specific strategies to reduce suicide rates. In this study, we wanted to investigate methods utilized and the psychosocial and mental health characteristics of youths (aged 12-26 y) who died by probable suicide. METHOD: We examined data from mental health clinical files and forensic reports and performed qualitative psychological autopsy interview from more than multiple sources for each youth who died by probable suicide between 1 May and 31 December 2015 in the Khyber Pakhtunkhwa Province of Pakistan. RESULTS: The two most common methods of probable suicide were by firearm use and self-poisoning utilizing pesticides that were significantly associated with male and female gender, respectively. The most common mental health difficulties were major depressive disorder and harmful use of psychoactive substances. Other clinical features particularly evident included thoughts of self-harm, irritability and aggression, low self-esteem, treatment nonadherence, family dispute, and financial distress. CONCLUSION: Efforts to reduce the ease of access to firearms and pesticides may potentially have a beneficial effect in reducing the suicide rate in this region of Pakistan. PMID- 30280520 TI - Generation and characterization of hepatocellular carcinoma cell lines with enhanced cancer stem cell potential. AB - Hepatocellular carcinoma (HCC) is one of the most common causes for cancer related death worldwide with rapidly increasing incidence and mortality rates. As for other types of cancers, also in HCC cancer stem cells (CSCs) are thought to be responsible for tumour initiation, progression and therapy failure. However, as rare subpopulations of tumour tissue, CSCs are difficult to isolate, thus making the development of suitable and reliable model systems necessary. In our study, we generated HepG2 subclones with enriched CSC potential by application of the spheroid formation method and subsequent single-cell cloning. Analyses in several 2D and 3D cell culture systems as well as a panel of functional assays both in vitro and in vivo revealed that the generated subclones displayed characteristic and sustained features of tumour initiating cells as well as highly aggressive properties related to tumour progression and metastasis. These characteristics could clearly be correlated with the expression of CSC markers that might have prognostic value in the clinical HCC setting. Therefore, we conclude that our CSC enriched HepG2 clones certainly represent suitable model systems to study the role of CSCs during HCC initiation, progression and drug resistance. PMID- 30280523 TI - Synapse-selective rapid potentiation of hippocampal synaptic transmission by 7,8 dihydroxyflavone. AB - AIM: The identification of 7,8-dihydroxyflavone (DHF) as a small molecule agonist for tropomyosin-related kinase B (TrkB) facilitated understanding of the role of TrkB signaling in regulating higher brain functions. DHF can penetrate the blood brain barrier after systemic administration and changes the performance of cognitive and emotional behavioral tasks. However, it is poorly understood how DHF modulates neuronal functions at cellular levels. Aiming to understand the cellular basis underlying DHF-induced modifications of the brain functions, we examined the effects of DHF on the hippocampal excitatory synaptic transmission. METHODS: Field excitatory postsynaptic potentials were recorded using hippocampal slices prepared from adult male mice. Effects of bath-applied DHF on the synaptic efficacy were examined. RESULTS: We found that DHF induced robust synaptic potentiation at the mossy fiber to CA3 synapse. DHF had minimal effects at other hippocampal excitatory synapses or at immature mossy fiber synapse in juvenile mice. The TrkB receptor blockers K252a and ANA-12 did not affect the DHF-induced synaptic potentiation. Drug screening revealed that relatively low concentrations of 2-aminoethoxydiphenylborane blocked the DHF-induced synaptic potentiation. CONCLUSION: Our results demonstrate that DHF selectively potentiates hippocampal mossy fiber synaptic transmission via a TrkB receptor-independent mechanism. This novel neuromodulatory effect of DHF may influence higher brain functions by itself or together with the activation of the TrkB receptor. The rapid induction of the potentiation implies its potential importance in the acute behavioral effects of DHF. PMID- 30280524 TI - The Care Continuum Universe: Delivering on the Promise.

As the development of new warheads, there are more and more applications of RDX with abnormal grain shapes. To ensure the operational effectiveness of the new warheads, it is necessary to find an on line nondestructive methods that can measure the RDX grain's internal pressure. In this paper, we use Raman spectrum and first-principles methods to determine the characteristic spectral line of the RDX samples and have studied the shift of the Raman spectral lines under various pressures. In particular, we measured the RDX samples under the pressures of 10, 20 and 30 MPa, respectively, and checked the fitting errors by measuring the RDX samples under the pressures of 15, 25 and 35 MPa, respectively. It is found that the shift of the characteristic Raman spectral line has a good linear dependence on the external pressures. Therefore, we can at first calibrate the linear relation between the shift of the Raman spectral line of regular RDX and the pressures in laboratory and then measure the Raman spectral line shift of the RDX with abnormal shapes. Based on the calibrated linear relation and the measurement of Raman spectra, one can determine the internal pressure in RDX. In this way, we can realize the nondestructive detection of the internal pressure of RDX. The experiment results show that this method has the advantage of good sensitivity and reproducibility. The Raman spectrum method has been successfully tested in the warhead production line. PMID- 30280537 TI - [Fluorescence Properties of Single-Trp Peptide: Response to pH and Metal Ions]. AB - Considering the important role of metal ions including copper ions are playing in human body, a novel single-Trp peptide WDAHSS was designed and synthesized in this study to achieve sensitive detection of copper ions via fluorescence spectroscopy. The intrinsic fluorescence of a tryptophan residue in WDAHSS, which was the only source of the molecular fluorescence, could be easily quenched with copper ions. By comparing fluorescence spectra of WDAHSS with those of tryptophan molecules at different pH values, the quenching mechanism of WDAHSS was explored in detail. Research showed that the histidine in WDAHSS bound copper ions with metal coordination. With participation of peptide bond, a square planar structure was formed. It was a consequent chelation of copper ions that caused the quenching of tryptophan residue. At the same time, this study discussed how pH conditions affected the fluorescence spectra of WDAHSS. Furthermore, association constants of copper ions towards WDAHSS were calculated through fluorescence measurements and fitting analyses. To enhance the anti-jamming ability to pH variation, the amino terminal of WDAHSS was intentionally acetylized, leading to a stable fluorescence emission under physiological pH conditions. Besides, WDAHSS was designed as a special structure to enhance the selectivity and biocompatibility of its sensitive detection of copper ions. Further studies on WDAHSS may help to improve the fluorescence imaging detection in vivo. PMID- 30280538 TI - [Preliminary Study on Atom O in High-Enthalpy Flow Field]. AB - With Two-photon absorption laser-induced fluorescence(TALIF) technology, leads pulse laser in pure high-enthply flow field from the direction of perpendicular to flow field, and obtains the two-dimension atom O fluorescent signal with ICCD setting outside of test section on the vertical direction of flat made with flow field and laser, this signal reflects the relative concentration of atom O. In paper, given the experimental environment and experimental equipment, to ensure that excitation laser wavelength in experiment is the best one, different angular quantum number on ground state of atom O are tested; finally, it is determined that J=2, wavelength 225.584 nm shall be experimental excitation laser wavelength. To make sure that the obtaining atom O fluorescent signal is in unsaturated linear region, in same condition, changing the excitation laser energy from small to large to test fluorescent signal, ultimately acquiring laser energy linear region is below 3.4 mJ. To record ICCD fluorescent image clearly with optimum contrast, Nikon f=105 mm F/2.8 lens is chosen as experimental lens, and the results are got with an accumulation of 50 times exposure. By analyzing the experimental fluorescent signal, we can get two peak positions on left and right of central line about +/-50 mm wide which are generated with compressional wave in supersonic flow field, and atom O concentration has 60 mm wide uniform area in central zone of subsonic flow field, the concentration decreases dramatically. This phenomenon is consistent with flow characteristics of wind tunnel, so the method can be applied to flow parameters measurement in the future. PMID- 30280539 TI - [Separation of Chlorophyll Fluorescence from Scattering Light of Algal Water Based on the Polarization Technique]. AB - Once chlorophyll molecules within the planktonic algae cells absorb light energy, they will release energy in the form of chlorophyll fluorescence emission. The elastic scattering light of particles in water is partially polarized, while chlorophyll fluorescence is unpolarized, so we can use the properties to separate the fluorescence signal from total scattering spectra for further retrieval the concentration of chlorophyll. But for coastal waters, the approach feasibility is still unclear. Based on this, we conducted the experiment in laboratory to analyze the influence of different concentrations of inorganic particles (IOP) and chlorophyll on the fluorescence extraction using polarization discrimination technique. The results indicate that, for algae water with different concentrations of IOP, the fluorescence peak will decrease while the concentration increase, but the retrieval result is still reliable when the concentration up to 300 mg.L(-1). For algae water with different concentrations of chlorophyll, the concentration of chlorophyll more higher, the efficiency of extracted fluorescence using polarization method is better, for common water, this approach can still work. The study proves that the polarization method is also applicable for complex water; it is of great importance for further detecting the concentration of chlorophyll in coastal waters using remote sensing.

PMID- 30280541 TI - [Application of Two-Dimensional Near-Infrared Correlation Spectroscopy in the Specificity Analysis of Noninvasive Blood Glucose Sensing]. AB - In this paper, two-dimensional (2D) correlation spectroscopy analysis was applied to investigate the influence of the main component in blood and the systematic drift during the measurement on the specificity of glucose in the near-infrared (NIR) spectroscopy. First, the NIR transmittance of glucose aqueous solutions was measured and the 2D correlation NIR spectra were calculated under the perturbation of glucose concentration. Based on the comparative analysis for synchronous and asynchronous 2D correlation spectra, the characteristic absorption peaks of glucose in the combination band and the overtone band were determined. Then a small amount of albumin was added into glucose aqueous solutions, and the transmittance was recorded to perform 2D correlation spectroscopy analysis under the perturbation of glucose concentration. However, the absorption of glucose in the first overtone band (1590nm) and second overtone band (1195nm) was no longer homologous in the 2D correlation spectra, which means that the albumin may reduce the specificity of glucose. Further, the oral glucose tolerance test of healthy volunteer was conducted and the NIR diffuse reflectance of left palm was collected in vivo. The 2D correlation analysis results showed that, the homology of glucose in the diffuse reflectance was also destroyed. Moreover, as the spectral variation from the glucose concentration change is too low to be covered by that induced by systematic drift easily, some background correction methods were usually required. For the transmittance experiment of glucose aqueous solutions and the diffuse reflectance experiment of human body, the pure water sample and 5% diffuse reflectance standard were used as the reference, respectively. Then 2D correlation spectroscopy was developed under the perturbation of measurement time. Results showed that, smaller band shift was observed in the slice spectra of 2D correlation synchronous spectra after the corresponding background correction, and the specificity of glucose was improved both in the in vitro and in vivo experiments. So for the non-invasive glucose sensing by NIR spectroscopy, the wavelengths should be chosen carefully to avoid the absorption band of some interfering components which may destroy the homology of glucose and make spectral interpretation more complicated. And the selection of reference samples for relative measurement is also important to improve the specificity of glucose.

AB - The paper presents the results of a study of 83 patients with gastroesophageal reflux disease, hypertension and in their comorbidial course. The purpose of the study is to examine the characteristics of heart rate variability (HRV) in the given cohort of patients. Materials and Methods: The main group consisted of 68 patients with a mean age of 35,37 +/- 10,34 years. Patients with isolated pathologies: 20 - with gastroesophageal reflux disease (GERD), 25 - with arterial disease (hypertension) without concomitant diseases. 23 patients had a combination of hypertension and GERD. The comparison group consisted of 15 healthy men. All the subjects were comparable in terms of age, sex, duration of Arterial hypertension and GERD. Results: Patients with associated course of arterial hypertension and GERD were found to have distinctions in HRV parameters, which indicate an increase in sympathetic nervous system activation and a decrease in parasympathetic influence. HRV was non-uniform in patients with different clinical and endoscopic GERD variants. In patients with endoscopically positive GERD (EPRD), there was a significant increase in both time (SDNN, SDANN, SDNN-index), and spectral parameters of HRV (VLF, HF). Conclusion: In associated course of acid dependent diseases (GERD) and hypertension, time and spectral parameters of heart rate variability significantly reduce, reaching the lowest values in patients with signs of reflux esophagitis. Comorbidity of GERD and hypertension exacerbates originally existing excessive influence of the sympathetic nervous system in patients with hypertension, leading to parasympathetic failure, and, ultimately, significantly weakening adaptive capabilities. Revealed changes in HRV parameters among patients with the given sintropy defines such a combination of diseases as undesirable, both for cardiovascular and autonomic nervous systems.

PMID- 30280544 TI - [Online Analysis of Dynamic Trend Regression and Endpoint Determination for Chinese Traditional Medicine Extraction Process Based on Ultraviolet spectroscopy]. AB - With the transition of Chinese traditional medicine manufacture industry, modernization has become the inexorable tendency in its future development. However, during the current Chinese traditional medicine producing process, the lack of online monitoring leads to the lagging of quality detection, as well as quality differences between products. In this paper, aiming at realizing online monitoring and end point automatic determination for Chinese traditional medicine (CTM) extraction unit, which is one of the most important units in CTM producing, ultraviolet (UV) spectroscopy is applied to build UV absorbance dynamic model based on the Lambert-Beer law and the CTM extraction kinetic model which presents a new method of UV absorbance dynamic analysis and endpoint determination, including curve regression, robustness analysis and endpoint calculation. In the experiment for online monitoring homalomena occulta extraction, the online UV spectral collection system for CTM extraction, developed by our laboratory, was applied for spectral collection; meanwhile, solid component contents in the offline samples were measured as reference. During the analysis, first of all, we pretreated the spectrum collected in the current period with interpolation and smoothing, and calculated the mean value within a UV region of 230.2~400 nm to form an absorbance mean value sequence with data obtained in the early measurements; then we verified the linear correlation between the sequence of absorbance and the concentrations of effective component in the solution, the linear correlation coefficient equals 0.982 8, showing a high linearity between UV spectra and solid component contents; finally, we regressed the absorbance mean value sequence with the dynamic model, analyzing its robustness and the extraction endpoint. Experimental results demonstrate that, the robustness analysis could recognize the bad points of measurement during the regression process, and improve the consistency between the regression and the original curves, raising its squared correlation coefficient to more than 0.99; meanwhile, with endpoint determination, we shortened the homalomena occulta extraction process from the original manually set 180 to 122 min effectively. The experiment above proves that this method with UV spectroscopy realizes online monitoring and automatic endpoint determination for the CTM extraction process, and is of significant importance for stabilizing production as well as improving economic benefit.

AB - Objective of the investigation was to examine clinical characteristics of peptic duodenal ulcer (DU) associated with arterial hypertension (AH) after acute gastrointestinal bleeding (AGB). The study included 25 patients with AH associated with DU, 45 patients with AH in AGB, 63 patients with AGB without AH, 48 patients with AH without AGB and 69 patients with DU without AH. If AH joins the existing DU, it increases the intensity of pain and dyspeptic syndromes. If DU joins AH, on the other hand, the clinical picture of ulcer disease was unclear. The largest concentration of Helicobacter pylori antibodies was found in patients with AH in AGB. Hypertensive crises were detected more often in combination of AH and DU.

AB - In the process of X-ray computed tomography (CT) imaging, the traditional single energy X-ray CT imaging technology is only applicable to structural analysis but can't meet the needs of functioning for substance distinction and identification because of the multispectral hardening artifacts and inconsistency between the projection acquisition process and reconstruction assumption. A multispectral CT imaging method based on the spectrum matching priors is presented. First, energy spectrum filtering matching model is built and range spectrum parameters are set according to the material composition; then multi-spectrum projection sequence is acquired by filtering. Second, the different reference energy is selected according to the material composition, befor using the improved Algebraic Reconstruction Techniques (ART) to achieve a multi-spectral CT imaging. Simulation result shows that we improved the contrast of the reconstructed image effectively, while meeting the needs of substance distinction. The actual data collection process is achieved by reconstructing in different spectrum and different corresponding reference energy.

The linear concentration range of DMP solution at the range of 250~400 nm is 0.5~70 mmol.L(-1). At 275 nm, the linear fitting equation is A=0.030 7c+0.133 0 with a correlation of 0.980 9. The detection limitation is 9.46*10-5 mmol.L-1, the RSD (n=6) of the method were at the range of 0.100%~0.612%. The recovery ratio for salt solutions sample is 95%~104%. Temperature, pH, and coexisting K(+), Na(+), Mg(2+), Cl(-), Br(-), I( ), SO(2-)(4) ions do not affect the detection. The coexisting CO(2-)(3) and HCO( )(3) ions can be eliminated with acidification. The results showed that the proposed method is simple in pretreatment process and has high accuracy and precision. It is a quick measurement method of DMP concentration in water solution, and can be used to measure DMP concentration in reverse flotation tail liquid and reverse flotation material pulp.

AB - Objectives: The aim of our study was to investigate associations between the lipid profile, liver condition and the level of BMI. Methods: Our sample consisted of 58 patients: 30 - with morbid obesity and BMI - 40-49 (1 group), 28 with superobesity, BMI - 50-69 (2 group). Lipids and hepatic functional tests were measured just prior to surgery. Ultrasound examination was used to estimate liver condition. Liver biopsy specimens were obtained at the time of surgery, classified according to the nonalcoholic fatty liver disease and steatohepatitis activity score. Results: Lower level of cholesterol has been found in the first group with morbid obesity. Higher level of triglycerides and very low-density lipoprotein has been found in the second group with superobesity (r=0,000 ANOVA). High-density lipoprotein was normal but significantly associated with BMI. The level of low-density lipoprotein was higher in the second group, but the difference between ptoups was not significant. BMI was associated with higher scores of ultrasonographic parameters and severity of steatosis, the increased prevalence of steatohepatitis and it activity. We also realized the positive correlation between ultrasonographic parameters and histological features. Conclusion: BMI has significantly positive correlations with the level of triglycerides and very low-density lipoprotein, ultrasonographic parameters, histological features of steatosis and steatohepatitis. The level of total cholesterol did not reflect all changes of lipid profile.

AB - Simultaneously achieving high piezoresistive sensitivity, stretchability, and good electrical conductivity in conductive elastomer composites (CECs) with carbon nanofillers is crucial for stretchable strain sensor and electrode applications. Here, we report a facile and environmentally friendly strategy to realize these three goals at once by using branched carbon nanotubes, also known as the carbon nanostructure (CNS). Inspired by the brick-wall structure, a robust segregated conductive network of a CNS is formed in the thermoplastic polyurethane (TPU) matrix at a very low filler fraction, which renders the composite very good electrical, mechanical, and piezoresistive properties. An extremely low percolation threshold of 0.06 wt %, currently the lowest for TPU based CECs, is achieved via this strategy. Meanwhile, the electrical conductivity is up to 1 and 40 S/m for the composites with 0.7 and 4 wt % CNS, respectively. Tunable piezoresistive sensitivity dependent on CNS content is obtained, and the composite with 0.7 wt % filler has a gauge factor up to 6861 at strain epsilon = 660% (elongation at break is 950%). In addition, this strategy also renders the composites' attractive tensile modulus. The composite with 3 wt % CNS shows 450% improvement in Young's modulus versus neat TPU. This work introduces a facile strategy to fabricate highly stretchable strain sensors by designing CNS network structures, advancing understanding of the effects of polymer-filler interfaces on the mechanical and electrical property enhancements for polymer nanocomposites.

AB - In this study, we developed a novel and efficient process for the fabrication of resistive strain gauges for healthcare-related applications. First, 1,9 nonanedithiol cross-linked gold nanoparticle (GNP) films were prepared via layer by-layer (LbL) spin-coating and subsequently transferred onto flexible polyimide foil by contact printing. Four-point bending tests revealed linear response characteristics with gauge factors of ~14 for 4 nm GNPs and ~26 for 7 nm GNPs. This dependency of strain sensitivity is attributed to the perturbation of charge carrier tunneling between neighboring GNPs, which becomes more efficient with increasing particle size. Fatigue tests revealed that the strain-resistance performance remained nearly the same after 10.000 strain/relaxation cycles. We demonstrate that these sensors are well suited to monitor muscle movements. Furthermore, we fabricated all-printed strain sensors by directly transferring cross-linked GNP films onto soft PDMS sheets equipped with interdigitated electrodes. Due to the low elastic modulus of poly(dimethylsiloxane) (PDMS), these sensors are easily deformed and, therefore, they respond sensitively to faint forces. When taped onto the skin above the radial artery, they enable the well-resolved and robust recording of pulse waves with diagnostically relevant details.

AB - The quality of the perovskite absorber is known to be the most crucial parameter for the photovoltaic performance of perovskite solar cells. By combining the one step anti-solvent engineering method followed by gas blowing, MAPbI3 film containing highly oriented multi-crystalline nanograins (150~500 nm) was made first. A user-friendly, simple, large-throughput, and reproducible post-solvent annealing (made by treating the film with anti-solvent containing H2O under spinning) was used to enlarge the perovskite grains up to 1.5 MUm. Inverted (p-i n) perovskite solar cells based on this highly ordered, large-grain MAPbI3 film achieve the highest efficiency of 21% with an extremely high fill factor (FF) of 86%. The high-efficiency cell shows almost no current hysteresis and is stable under 1 sun illustration in a glovebox or standing in the ambient atmosphere (20~25 degrees C, ca. 30% humidity) under room lighting (T5 lamp, 500 lux). A creative method combining the gas blowing with quick and simple post-treatment to prepare a highly oriented MAPbI3 film with large multi-crystalline grains to achieve excellent photovoltaic performance was demonstrated. This creative film preparation method was also successfully applied to fabricate large area MAPbI3 film for high-efficiency perovskite mini-modules. Being able to control the crystallization and growth of perovskite crystallites definitely makes the fabrication of perovskite solar cells more reproducible.

AB - In semiconductor heterojunction, polarity critically governs the physical properties, with an impact on electronic or optoelectronic devices through the presence of pyroelectric and piezoelectric fields at the active heteropolar interface. In the present work, the abrupt O-polar ZnO/Ga-polar GaN heterointerface was successfully achieved by using high O/Zn ratio flux during the ZnO nucleation growth. Atomic-resolution high-angle annular dark-field and bright-field transmission electron microscopy observation revealed that this polarity inversion confines within one monolayer by forming the (0001) plane inversion domain boundary (IDB) at the ZnO/GaN heterointerface. Through theoretical calculation and topology analysis, the geometry of this IDB was determined to possess an octahedral Ga atomic layer in the interface, with one O/N layer symmetrically bonded at the tetrahedral site. The computed electronic structure of all considered IDBs revealed a metallic character at the heterointerface. More interestingly, the presence of two-dimensional (2D) hole gas (2DHG) or 2D electron gas (2DEG) is uncovered by investigating the chemical bonding and charge transfer at the heterointerface. This work not only clarifies the polarity control and interfacial configuration of the O-polar ZnO/Ga-polar GaN heterojunction but, more importantly, also gives insight into their further application on heterojunction field-effect transistors as well as hybrid ZnO/GaN optoelectronic devices. Moreover, such polarity control at the monolayer scale might have practical implications for heterojunction devices based on other polar semiconductors.

AB - The expansion of electrochemical sensors to biomedical applications at point of care requires these sensors to undergo analysis without any pretreatment or extraction. This poses a major challenge for all electrochemical sensors including electrochemiluminescent (ECL)-based sensors. ECL offers many advantages for biomedical applications; however, obtaining results from complex matrixes has proven to be a large hurdle for the application of ECL sensors within this field. This work demonstrates the potential of cathodic ECL to detect and quantify homocysteine (Hcy) with a 0.1 nM limit of detection, which is associated with hyperhomocysteinemia, in blood. This near-infrared quantum dot (NIR QD)-based ECL sensor displays good linearity allowing for rapid detection and providing a basis for exploitation of ECL-based sensors for biomedical diagnostics utilizing Hcy as a model cathodic coreactant. This work will lay the foundations for future developments in biosensing and imaging fields and stands as an initial proof of concept for the utilization of cathodic ECL technologies for biomedical applications once the limits of detection within clinically relevant levels has been achieved. This work illustrates the potential of cathodic ECL sensors, using Hcy as a model complex, for the detection of biomolecules. PMID- 30280563 TI - Construction of Highly Hierarchical Layered Structure Consisting of Titanate Nanosheets, Tungstate Nanosheets, Ru(bpy)32+, and Pt(terpy) for Vectorial Photoinduced Z-Scheme Electron Transfer. AB - To imitate the precisely ordered structure of the photoantennas and electron mediators in the natural photosynthesis system, we have constructed the Ru(bpy)32+-intercalated alternate-layered structure of titanate nanosheets and tungstate nanosheets via thiol-ene click reaction. Before nanosheet stacking, Pt(terpy) was immobilized at the edge of the titanate nanosheets. The visible light-induced vectorial Z-scheme electron transfer reaction from the valence band of tungstate to the conduction band of titanate via the photoexcited Ru(bpy)32+ was demonstrated by the following two evidences: (1) From the results of the fluorescence decay of Ru(bpy)32+, the rate of the forward electron transfer from the photoexcited Ru(bpy)32+ to the conduction band of titanate was estimated as 1.16 * 108 s-1, which was 10 times faster than the backward electron transfer from the photoexcited Ru(bpy)3 to the conduction band of tungstate (1.02 * 107 s 1) due to a localization of Ru(bpy)32+ on the titanate nanosheets. (2) We observed the decrease of the electrons accumulated in the conduction band of the tungstate induced by photoexcitation of Ru(bpy)32+, demonstrating the forward electron transfer from the conduction band of tugnstate to the vacant highest occupied molecular orbital level of the photoexcitation Ru(bpy)32+. Finally, H2 gas was produced from the water dispersion of the alternate-layered structure under visible light irradiation, suggesting that the electrons getting to the conduction band of the titanate were transferred to the Pt(terpy) placed at the edge of the nanosheets, and reduced water to dihydrogen. Herein, n-octylamine species at the interlayer space played a role as hole scavenger; in other words, these molecules were oxidized by the hole in the conduction band of the tungstate nanosheets. PMID- 30280564 TI - ReaxFF Molecular Dynamics Study on the Influence of Temperature on Adsorption, Desorption, and Decomposition at the Acetic Acid/Water/ZnO(1010) Interface Enabling Cold Sintering. AB - The reaction dynamics of a liquid-solid interface with the example of an acetic acid/water solution interacting with a ZnO(1010) surface was investigated using ReaxFF reactive force field-based molecular dynamics. The interactions were studied over a broad temperature range to assess the kinetics and reaction pathways. Two different acetic acid dissociation mechanisms are observed in the simulations: (1) deprotonation to surface cation, which produces a terminal hydroxyl and (2) deprotonation to a bridging hydroxyl, which results in water production. An increase in temperature promotes the dissociation of acetic acids and its adsorption to surface at first, but as the temperature increase continues, the surface coverage by acetates decreases due to evaporation from the surface or decomposition. The acetate decomposition starts with a nucleophilic attack of oxygen to methyl carbon and results in the production of carbon dioxide, which is consistent with experimental findings in the literature. The coverage of the surface by water molecules decreases as the system is heated up, which is also observed in other molecular dynamics studies. At elevated temperatures, acetate molecules are more stable than water molecules or bridging hydroxyls on the surface. These simulations validate the ReaxFF method for the water/organic mixture and metal oxide surface interactions and provide insights into structure and reactivity of aqueous solvents on metal oxide surfaces at elevated temperatures. Adsorption trends that are observed in this study are consistent with phenomenological Langmuir models. The reaction of acetic acid decomposition to smaller molecules such as CO2 and CH2O agrees with experimental observations. Understanding the details of these dynamic surface reactions are critical to understand important new cold sintering processes that utilize transient liquid and solid reactions, and the latter could be used to predict solvent selection for cold sintering. PMID- 30280565 TI - Enhanced Environmental Stability Coupled with a 12.5% Power Conversion Efficiency in an Aluminum Oxide-Encapsulated n-Graphene/p-Silicon Solar Cell. AB - A significant improvement in the power conversion efficiency (PCE) and the environmental stability of n-Graphene/p-Si solar cells is indicated through effective n-doping of graphene, using low work function oxide capping layers. AlO x, deposited through atomic layer deposition, is particularly effective for such doping and in addition serves as an antireflection coating and a cell encapsulating layer. It is shown that the related charge transfer doping and interfacial engineering was crucial to achieve a record PCE of 12.5%. The work indicates a path forward, through work function engineering, for further efficiency gains in Gr-based solar cells. PMID- 30280567 TI - The Muscarinic Acetylcholine Receptor M5: Therapeutic Implications and Allosteric Modulation. AB - The muscarinic acetylcholine receptor (mAChR) subtype 5 (M5) was the most recent mAChR to be cloned and has since emerged as a potential therapeutic target for a number of indications. Early studies with knockout animals have provided clues to the receptor's role in physiological processes related to Alzheimer's disease, schizophrenia, and addiction, and until recently, useful subtype-selective tools to further probe the pharmacology of M5 have remained elusive. Small-molecule allosteric modulators have since gained traction as a means by which to selectively examine muscarinic pharmacology. This review highlights the discovery and optimization of M5 positive allosteric modulators (PAMs) and negative allosteric modulators (NAMs). PMID- 30280566 TI - Nonenzymatic Polymerization into Long Linear RNA Templated by Liquid Crystal Self Assembly. AB - Self-synthesizing materials, in which supramolecular structuring enhances the formation of new molecules that participate to the process, represent an intriguing notion to account for the first appearance of biomolecules in an abiotic Earth. We present here a study of the abiotic formation of interchain phosphodiester bonds in solutions of short RNA oligomers in various states of supramolecular arrangement and their reaction kinetics. We found a spectrum of conditions in which RNA oligomers self-assemble and phase separate into highly concentrated ordered fluid liquid crystal (LC) microdomains. We show that such supramolecular state provides a template guiding their ligation into hundred bases long chains. The quantitative analysis presented here demonstrates that nucleic acid LC boosts the rate of end-to-end ligation and suppresses the formation of the otherwise dominant cyclic oligomers. These results strengthen the concept of supramolecular ordering as an efficient pathway toward the emergence of the RNA World in the primordial Earth. PMID- 30280568 TI - Single-Molecule Kinetic Investigation of Cocaine-Dependent Split-Aptamer Assembly. AB - Aptamers are short nucleic-acid biopolymers selected to have high affinity and specificity for protein or small-molecule target analytes. Aptamers can be engineered into split-aptamer biosensors comprising two nucleic acid strands that coassemble as they bind to a target, resulting in a large signal change from attached molecular probes (e.g., molecular beacons). The kinetics of split aptamer assembly and their dependence on target recognition are largely unknown; knowledge of these kinetics could help in design and optimization of split aptamer biosensors. In this work, we measure assembly kinetics of cocaine dependent split-aptamer molecules using single-molecule fluorescence imaging. Assembly is monitored between a DNA strand tethered to a glass substrate and solutions containing the other strand tagged with a fluorescent label, with varying concentrations of the cocaine analyte. Dissociation rates are measured by tracking individual molecules and measuring their bound lifetimes. Dissociation time distributions are biexponential, possibly indicating different folded states of the aptamer. The dissociation rate of only the longer-lived complex decreases with cocaine concentration, suggesting that cocaine stabilizes the long-lived aptamer complex. The variation in the slow dissociation rate with cocaine concentration is well described with an equilibrium-binding model, where the dissociation rate approaches a saturation limit consistent with the dissociation equilibrium constant for cocaine-binding to the split aptamer. This single molecule methodology provides a sensitive readout of cocaine-binding based on the dissociation kinetics of the split aptamer, allowing one to distinguish target dependent aptamer assembly from background assembly. This methodology could be used to study other systems where target association affects the stability of aptamer duplexes. PMID- 30280569 TI - Fabrication of Air-Stable and Conductive Silk Fibroin Gels. AB - Owing to their promising applications in flexible electronics, researchers have extensively explored flexible and conductive gels. However, these gels have unsatisfactory strength and flexibility as well as easily dry in air. Herein, a rationally designed robust regenerated silk fibroin (RSF)-based gel with significant flexibility and strength, favorable conductivity, and excellent air stability is fabricated by inducing the conformation transition of RSF from random coil to beta-sheet in ionic liquid (IL)/water mixtures. We found that such RSF-based gels have a unique homogeneous network structure of RSF nanofibers, which is likely formed because of evenly distributed cross-links dominated by small-sized beta-sheet domains created during the conformation transition of RSF. Although the unique homogeneous nanostructure/network contributes toward improving the mechanical properties of these gels, it also provides pathways for ionic transport to help the gels preserve high conductivity of ILs. The prepared RSF-based gels display a remarkable air stability and reversible loss/absorption water capability in a wide humidity range environment primarily because of the distinguished combination of the IL and water. Therefore, the novel RSF-based gels hold a great potential in various applications as multifunctional, flexible, conductive materials, which are dispensed with encapsulation. PMID- 30280570 TI - Nanoid Canyons On-Demand: Electrically Switchable Surface Topography in Liquid Crystal Networks. AB - Topography is a key factor that governs important properties of surfaces, such as adhesion and wettability, and materials with switchable surface topographies will have switchable surface properties. We demonstrate a principle to generate electrically switchable surface topographies on the surface of a thin nematic liquid crystal elastomer film which is sandwiched between a continuous electrode and a random metal network. Voltage-controlled displacement of the metal network toward the continuous electrode is achieved, resulting in unprecedented topographical modulations in the range of 0-2.5 MUm. We show that this depth variation is significantly larger than the expected deformation because of electrostatic attraction between the network and the continuous electrode. This effect is explained by deformation due to the rotation of the liquid crystal side groups along the electric field lines. PMID- 30280571 TI - Stability and Transport of Spent Hen-Derived ACE-Inhibitory Peptides IWHHT, IWH, and IW in Human Intestinal Caco-2 Cell Monolayers. AB - Ile-Trp-His-His-Thr (IWHHT), initially identified as an ACE inhibitory peptide, was shown to have antioxidant and anti-inflammatory activities in cells and blood pressure lowering activity in animals. IWHHT was degraded into IWH and IW during simulated gastrointestinal digestion. The purpose of this study was to investigate the stability, permeability, and transport pathways of IWHHT, IWH, and IW across intestinal epithelium using human intestinal Caco-2 cell monolayers. IWHHT, IWH, and IW were partly degraded by aminopeptidase N or dipeptidyl peptidase IV, but they were transported intact, with apparent permeability coefficients of (22.0 +/- 1.42) * 10-8, (37.5 +/- 1.11) * 10-8, and (19.6 +/- 0.62) * 10-8 cm s-1, respectively. The results firstly evidenced an important role of aminopeptidase N in cleaving small ACE inhibitory peptides during transport. IWH was transported via both peptide transporter 1 (PepT1) and paracellular route, while IW was via PepT1 and IWHHT was via paracellular route only. Transport of IW implied that hydrophobic peptides (even with a small size), consisting of only highly hydrophobic amino acid residues, might not be transported via paracellular diffusion. This study suggested that all three peptides could pass through the intestinal epithelium and that the degraded IWH and IW might also contribute to the antihypertensive activity of IWHHT.

The resulting structure shows a very efficient through-space energy transfer (FRET), acting as an energy funnel. Thus, maximum solar output in the visible region can be collected and converted into red light, which can be transformed efficiently with a fine-tuned photovoltaic device. The versatility of the synthetic pathway demonstrates the potential utility of rotaxane-based energy harvesting supramolecules assemblies. PMID- 30280573 TI - Lepadins I-K, 3- O-(3'-Methylthio)acryloyloxy-decahydroquinoline Esters from a Bahamian Ascidian Didemnum sp. Assignment of Absolute Stereostructures. AB - Three decahydroisoquinoline alkaloids, lepadins I-K, were isolated from a specimen of Didemnum sp. collected in the Bahamas. The structures of the new compounds were assigned by an integrated analysis of MS, IR, and 1H, 13C, and 2D NMR spectra. Like previously reported lepadins, the structures of the new compounds contain a decahydroquinoline heterocyclic core in lepadin I, and a new variation, an octahydroquinoline in lepadin J, but differ from earlier reported compounds by acylation of the 3-hydroxyl group by a rare 3'-methylthioacrylate. The absolute configuration of lepadin I was solved by interpretation of NOE measurements, and exciton coupled circular dichroism (ECCD) of the corresponding N- p-bromobenzoyl derivative. The latter constitutes a general method for determination of absolute configuration of the entire lepadin family. The configuration of the remote side-chain secondary carbinol was solved by the modified Mosher's esters method. Lepadin I inhibited butyrylcholineesterase (BuChE, IC50 3.1 MUM), but only weakly inhibited acetylcholineesterase (AChE) (10% at 100 MUM).

AB - Luteolin is a flavonoid present in plants in the form of aglycone or glucosides. In this study, luteolin glucosides (i.e., luteolin-7- O-beta-d-glucoside, luteolin-7- O-[2-(beta-d-apiosyl)-beta-d-glucoside], and luteolin-7- O-[2-(beta-d apiosyl)-6-malonyl-beta-d-glucoside]) prepared from green pepper leaves as well as luteolin aglycone were orally administered to rats. Regardless of the administered luteolin form, luteolin glucuronides were mainly detected from plasma and organs. Subsequently, luteolin aglycone, the most absorbed form of luteolin in rats, was orally administered to humans. As a result, luteolin-3'- O sulfate was mainly identified from plasma, suggesting that not only luteolin form but also animal species affect the absorption and metabolism of luteolin. When LPS-treated RAW264.7 cells were treated with luteolin glucuronides and luteolin sulfate (the characteristic metabolites identified from rats and humans, respectively), the different luteolin conjugates were metabolized in different ways, suggesting that such difference in metabolism results in their difference in anti-inflammatory effects. PMID- 30280577 TI - Chromosome 17 Missing Proteins: Recent Progress and Future Directions as Part of the neXt-MP50 Challenge. AB - The Chromosome-centric Human Proteome Project (C-HPP), announced in September 2016, is an initiative to accelerate progress on the detection and characterization of neXtProt PE2,3,4 "missing proteins" (MPs) with a mandate to each chromosome team to find about 50 MPs over 2 years. Here we report major progress toward the neXt-MP50 challenge with 43 newly validated Chr 17 PE1 proteins, of which 25 were based on mass spectrometry, 12 on protein-protein interactions, 3 on a combination of MS and PPI, and 3 with other types of data. Notable among these new PE1 proteins were five keratin-associated proteins, a single olfactory receptor, and five additional membrane-embedded proteins. We evaluate the prospects of finding the remaining 105 MPs coded for on Chr 17, focusing on mass spectrometry and protein-protein interaction approaches. We present a list of 35 prioritized MPs with specific approaches that may be used in further MS and PPI experimental studies. Additionally, we demonstrate how in silico studies can be used to capture individual peptides from major data repositories, documenting one MP that appears to be a strong candidate for PE1. We are close to our goal of finding 50 MPs for Chr 17. PMID- 30280576 TI - Multiproteases Combined with High-pH Reverse-Phase Separation Strategy Verified Fourteen Missing Proteins in Human Testis Tissue. AB - Subsequent to conducting the Chromosome-Centric Human Proteome Project, we have focused on human testis-enriched missing proteins (MPs) since 2015. For protein coverage to be enhanced, a multiprotease strategy was used for separation of samples by 10% SDS-PAGE. For the separating efficiency to be improved, a high-pH reverse phase (RP) separation strategy was applied to fractionate complex samples in this study. A total of 11,558 proteins was identified, which is the largest proteome data set for single human tissue sample so far. On the basis of this large-scale data set, we verified 14 MPs (PE2) in neXtProt (2018-01) after spectrum quality analysis, isobaric post-translational modification, and single amino acid variant filtering, and synthesized peptide matching. Tissue expression analysis showed that 3 of 14 MPs were testis-specific proteins. Functional analysis showed that 10 of 14 MPs were closely related to liver tumor, liver carcinoma, and hepatocellular carcinoma. Another 100 MPs were listed as candidates but required additional verification information. All MS data sets have been deposited into the ProteomeXchange with the identifier PXD009737.

AB - Young Black MSM (YBMSM) are disproportionately affected by violence, criminal justice involvement, and other structural factors that also increase vulnerability to HIV. This study examined associations between exposure to community violence (ECV) and substance use, psychological distress, and criminal justice involvement (CJI) among YBMSM in Chicago, IL. Respondent driven sampling was used to recruit a sample of 618 YBMSM (aged 16-29) from the South Side of Chicago between June 2013 and July 2014. Weighted logistic regression assessed the direct effects of ECV, CJI, and psychological distress on substance use outcomes. Indirect effects were assessed via path analysis with mean and variance adjusted weighted least squares estimation and sampling weights. Over 90% reported lifetime exposure to violence, 41% had history of CJI, and substance use was common. Almost one-third reported daily or more frequent marijuana use; 17% reported substance use related problems and drug use other than marijuana. ECV was directly and positively associated with CJI, psychological distress, and problematic substance use, with significant indirect effects from ECV to? problematic substance use via CJI and psychological distress. HIV prevention interventions for YBMSM should address the underlying contextual drivers of substance use and psychological distress, including violence exposure and criminal justice involvement.

AB - The American Academy of Pediatrics California Chapter 3 created a 20-minute training video targeting barriers to strong provider recommendation of the human papillomavirus (HPV) vaccine. The video included clinical vignettes featuring pediatricians modeling counseling techniques with vaccine-hesitant families. Ninety-six multidisciplinary providers (including pediatric residents) at 6 sites viewed the video and completed baseline and posttest questionnaires assessing their vaccine knowledge, attitudes toward vaccination, and comfort with skills needed to facilitate vaccination. Following the intervention, providers had substantial and statistically significant ( P < .05) improvements in multiple areas assessed, particularly knowledge of the burden of HPV-related disease in males and changes in vaccine response with age; likelihood of "strongly agreeing" that vaccination should not be delayed beyond preadolescence and that HPV vaccine is safe; and feeling "very comfortable" counseling vaccine-hesitant parents and facilitating vaccine completion. This cost-effective and easily disseminated training modality shows promise in increasing provider comfort with HPV vaccine counseling. PMID- 30280582 TI - Understanding preferences regarding consent for pragmatic trials in acute care. AB - BACKGROUND: There has been debate about the role of consent in pragmatic trials comparing qualitatively similar interventions. Consent preferences may differ in acute care contexts, given severe illness, time constraints, and other barriers to consent. In addition, studies have not assessed the impact of disclosing financial considerations as a justification for trials. This study was designed to assess preferences of the general public regarding consent for a pragmatic trial in ST-elevation myocardial infarction. METHODS: This survey was completed using an online, probability-based panel representative of the US population. It incorporated a randomized, experimental (2 * 2) design assessing (1) preference for written consent versus an alternative (notification after enrollment or brief verbal consent) and (2) impact of including cost as a motivating factor for the trial. The survey used a scenario based on a recent pragmatic trial in ST elevation myocardial infarction. Primary independent variables were personal preference and recommendation as a member of a review board regarding written consent versus the assigned alternative strategy and personal attitude toward trial enrollment. Descriptive analyses were conducted using post-stratification weights. Regression models were created to examine relationships between demographic variables and consent preference and willingness to enroll. Provision of cost information was incorporated into a regression model to examine its impact on consent preference. RESULTS: The study included 2027 participants. Of those participants, 51.1% versus 45.8% stated a personal preference for written consent versus notification after enrollment; however, 60.0% versus 35.5% preferred brief verbal consent to written consent. Even among respondents stating they would be unlikely to enroll in the trial if asked, more respondents (50.6%) preferred brief verbal consent. The preference for verbal consent was generally shared across demographic categories, although lower educational attainment was associated with reduced acceptance (p = 0.001 for trend). Respondents were more likely to support an alternative to written consent when asked their personal preference than when asked their recommendation as a member of a review board. The provision of cost information did not have a meaningful effect on consent preferences, attitudes toward enrollment, or views about the study. CONCLUSION: Respondents generally supported prospective involvement in enrollment decisions in the setting of acute myocardial infarction and were particularly supportive of brief verbal consent. This support persisted across demographic categories. The finding that individuals were more likely to support alternatives to written consent when asked for a personal preference rather than as a "committee member" suggests that conservative institutional approaches to consent could hinder implementation of more patient-centered approaches. The role of cost transparency in consent discussions warrants further study. PMID- 30280583 TI - Variability and Influencing Factors of QOL in Breast Cancer Patients Having Chemotherapy. AB - Variability and factors influencing quality of life (QOL) in breast cancer patients having chemotherapy were examined in a longitudinal prospective cohort study in two teaching hospitals in China. Physical, mental, social/family, and functional QOL changed significantly over time with varying patterns. In addition, various factors influenced the QOL of breast cancer patients at each chemotherapy cycle. Health professionals should focus on critical time periods during chemotherapy, particularly at baseline and during the fourth and fifth cycles when the QOL in our sample was at the lowest point, and they should provide additional support to patients to ensure that chemotherapy is delivered in an optimal fashion. PMID- 30280584 TI - Peripheral Eosinophilia Found in Pediatric Enterobius vermicularis Infections. AB - Enterobius vermicularis, the common pinworm, is well known in North America as a parasitic infection, mainly affecting children. It is a very contagious organism, and it is responsible for a high number of infections in the United States each year. A rise in eosinophilia is linked to most parasitic infections. However, the correlation between eosinophilia and enterobiasis infections is not well documented in the literature. In this article, we present 3 cases involving patients seen for pediatric gastroenterology consultation with concern for inflammatory bowel disease. As part of their evaluation, each patient was found to have eosinophilia of unknown significance with an ultimate diagnosis of pinworm infections made by endoscopy. Their illness presentation did not include classic enterobiasis symptoms such as rectal pruritus or nighttime irritability. These cases support a link between eosinophilia and enterobiasis that may be instructive for pediatric providers seeing patients with eosinophilia for which there is no readily apparent underlying cause. PMID- 30280585 TI - Faculty Attitudes Toward Rhinology Fellowship Training: A Survey of Rhinology Fellowship Programs. AB - Background The number of rhinology fellowship programs has grown rapidly over the past decade. To date, no standardization or accreditation process exists, raising the potential for disparate programs. The attitudes of faculty regarding training are important to elucidate the educational experience of rhinology fellowship. Methods An anonymous, web-based survey of rhinology faculty assessed the subjective attitudes toward various domains of fellowship training including surgery, office-based procedures, research, and career development. A 5-point Likert-type scale assessing importance was used (1-not at all important, 5 extremely important). Results A total of 34 faculty (response rate 35.8%) completed the survey. The surgical procedures that received the highest mean importance scores were endoscopic surgery for advanced inflammatory disease (median = 5), cerebrospinal fluid leak closure (5), and extended endoscopic sinus surgery (5). The procedures with the lowest scores were nasal valve repair (2), inferior turbinate surgery (3), and open approaches to the sinuses (4). A wide range of responses was noted for the minimum target number of fellow cases for the surveyed procedures. Higher importance scores were noted for direct attending supervision (5) when compared to fellow autonomy (4, P < .001) or shadowing (3.5, P < .001) in the operating room. Higher scores were noted for career preparation in academic (4) versus private practice (3, P < .001) and providing opportunities for clinical (4) versus basic science research (2, P < .001). The majority of faculty felt that there were too many fellowship positions with respect to the market place for private practice (58.8%), academic jobs (85.3%), and overall societal need (61.8%). Conclusion A range of faculty attitudes with respect to fellowship training was noted in this study. Continued assessment and refinement of the educational experience in rhinology fellowships is necessary. PMID- 30280587 TI - Co-occurrence of acute ophthalmoplegia (without ataxia) and idiopathic intracranial hypertension. AB - BACKGROUND: Acute ophthalmoparesis without ataxia was designated as 'atypical Miller Fisher syndrome' as it presents with progressive, relatively symmetrical ophthalmoplegia, but without ataxia nor limb weakness, in the presence of anti GQ1b antibody. Idiopathic intracranial hypertension is characterized by signs of raised intracranial pressure occurring in the absence of cerebral pathology, with normal composition of cerebrospinal fluid and a raised opening pressure of more than 20 cmH2O during lumbar puncture. We aim to report a rare case of acute ophthalmoplegia with co-occurrence of raised intracranial pressure. CASE DESCRIPTION: A 28-year-old gentleman with body mass index of 34.3 was referred to us for management of double vision of 2 weeks duration. His symptom started after a brief episode of upper respiratory tract infection. His best corrected visual acuity was 6/6 OU. He had bilateral sixth nerve palsy worse on the left eye and bilateral hypometric saccade. His deep tendon reflexes were found to be hyporeflexic in all four limbs. No sensory or motor power deficit was detected, and his gait was normal. Plantar reflexes were downwards bilaterally and cerebellar examination was normal. Both optic discs developed hyperaemia and swelling. Magnetic resonance imaging of brain was normal and lumbar puncture revealed an opening pressure of 50 cmH2O. Anti-GQ1b IgG and anti-GT1a IgG antibody were tested positive. CONCLUSION: Acute ophthalmoparesis without ataxia can present with co-occurrence of raised intracranial pressure. It is important to have a full fundoscopic assessment to look for papilloedema in patients presenting with Miller Fisher syndrome or acute ophthalmoparesis without ataxia.

AB - Objective To determine performance and repair kinetics of the ChonDux hydrogel scaffold for treating focal articular cartilage defects in the knee over 24 months. Design This assessor-blinded trial evaluates ChonDux hydrogel scaffold implantation in combination with microfracture in 18 patients across 6 sites. Male and female patients 18 to 65 years of age with full-thickness femoral condyle defects 2 to 4 cm2 in area were enrolled. Eligible patients received ChonDux treatment followed by rehabilitation. Defect volume fill was evaluated after 3, 6 (primary outcome), 12, 18, and 24 months by assessor blinded magnetic resonance imaging (MRI) analysis. Secondary outcomes were T2-weighted MRI relaxation time and patient surveys via visual analogue scale (VAS) pain and International Knee Documentation Committee (IKDC) knee function scoring. Results ChonDux maintained durable tissue restoration over 24 months with final defect percent fill of 94.2% +/- 16.3% and no significant loss of fill volume at any time points. Tissues treated with ChonDux maintained T2 relaxation times similar to uninjured cartilage between 12 and 24 months. VAS pain scoring decreased between 1 and 6 weeks, and IKDC knee function scores improved by approximately 30.1 with ChonDux over 24 months. Conclusion ChonDux treatment is a safe adjunct to microfracture therapy and promotes stable restoration of full thickness articular cartilage defects for at least 24 months.

AB - PURPOSE: To evaluate, through the in vivo confocal microscopy, the pathological changes of each corneal layer in eyes affected by pseudoexfoliation syndrome. METHODS: We studied 40 eyes of 40 patients with diagnosis of unilateral senile cataract associated with pseudoexfoliation syndrome and 40 eyes of 40 control subjects with senile cataract without pseudoexfoliation syndrome. All patients underwent a complete ophthalmic examination including best corrected visual acuity, slit-lamp examination, corneal sensitivity measurement using a Cochet Bonnet nylon thread esthesiometer, and anterior segment optical coherence tomography (Visante OCT, Carl Zeiss Meditec AG, Germany); in vivo confocal microscopy of corneal sections (endothelium, stroma, sub-basal nerve plexus, and superficial and basal epithelium) was performed with the ConfoScan 4.0 (Nidek, Japan). RESULTS: In pseudoexfoliation syndrome group, the mean corneal sensitivity was 44.1 +/- 1.3 mm and in the control group was 55.6 +/- 4.7 mm. The corneas of the eyes with pseudoexfoliation syndrome were significantly less sensitive than those of control group eyes (p < 0.001). Pseudoexfoliation syndrome eyes had a lower nerve density and less nerve beadings and a higher degree of tortuosity in sub-basal plexus compared to the control group. The cell density of epithelial and endothelial layers was significantly lower in pseudoexfoliation syndrome eyes than controls. In 80% of pseudoexfoliation syndrome eyes, we found activated keratocytes and inflammatory cells in the anterior stroma. CONCLUSION: Our study demonstrates the morpho-structural corneal alterations in eyes affected by pseudoexfoliation syndrome, using corneal in vivo confocal microscopy as a non-invasive and high-reproducible technique to evaluate pathophysiology of each corneal layer; the sub-basal nerve plexus alterations are correlated with the lower corneal sensitivity. PMID- 30280590 TI - Bilateral noncalcified astrocytic hamartomas in retinitis pigmentosa: Multimodal imaging evaluation over 8 years of follow-up. AB - PURPOSE: To report the evolution of optic disk noncalcified astrocytic hamartomas in a patient with retinitis pigmentosa throughout 8 years of follow-up. METHODS: Case report. RESULTS: A 42-year-old white man with a diagnosis of retinitis pigmentosa was referred to our medical retinal center for the first time in 2010, for the development of a new optic nerve head lesion in the right eye. Fundus examination, fundus autofluorescence, fluorescein and green indocyanine angiography, spectral-domain optical coherence tomography were performed and confirmed the presence of a papillary noncalcified astrocytic hamartoma in the right eye. Four years later, multimodal imaging evaluation revealed in the left eye the presence of a first optic disk benign tumor, and in 2018, a second in the nasal retina, while in the right eye the sole papillary lesion increased slightly in size. CONCLUSIONS: Noncalcified astrocytic hamartomas can occur in patients with retinitis pigmentosa and can increase in size and number in time. A complete multimodal imaging evaluation is necessary to identify and classify any kind of new lesion that, as known, are associated with these group of hereditary retinal degenerations. PMID- 30280589 TI - Molecular modelling studies on cinnoline-based BTK inhibitors using docking and structure-based 3D-QSAR. AB - BTK inhibitors have been proved as an effective target for B-cell malignancies. Ibrutinib is the most advanced irreversible BTK inhibitor for treating mantle cell lymphoma/chronic lymphocytic leukaemia but with existing drug resistance and adverse effects. To design novel effective and safety reversible BTK inhibitors, 115 newly cinnoline analogues were selected to perform molecular docking and 3D QSAR study because of the main scaffold similarity to Ibrutinib. Both established CoMFA and CoMSIA models obtained high predictive and satisfactory value. CoMFA/CoMSIA contour maps demonstrated that bulky substitutions are preferred at R1 and R3 positions, and introducing hydrophilic and negative electrostatic substitutions at R1 positions is important for improving BTK inhibitory activities. These results will be useful to provide clues for rationally designing novel and high potency BTK inhibitors. PMID- 30280591 TI - Amplitude Instability of Somatosensory Evoked Potentials as an Indicator of Delayed Cerebral Ischemia in a Case of Subarachnoid Hemorrhage. AB - We describe a 55-year-old male patient with a subarachnoid hemorrhage (SAH) as a result of left middle cerebral artery (MCA) aneurysm rupture, who underwent continuous electroencephalogram (EEG) and somatosensory evoked potential (cEEG SEP) monitoring that showed an unusual SEP trend pattern. EEG was continuously recorded, and SEPs following stimulation of median nerves were recorded every 50 minutes, with the amplitude and latency of the cortical components automatically trended. An increase in intracranial pressure required a left decompressive craniectomy. cEEG-SEP monitoring was started on day 7, which showed a prolonged (24 hours) instability of SEPs in the left hemisphere. During this phase, left MCA vasospasm was demonstrated by transcranial Doppler (TCD), and computed tomography perfusion (CTP) showed a temporo-parieto-occipital ischemic penumbra. Following intravascular treatment, hypoperfusion and the amplitude of cortical SEPs improved. In our case, a prolonged phase of SEP amplitude instability during vasospasm in SAH correlated with a phase of ischemic penumbra, as demonstrated by CTP. In SAH, SEP instability during continuous monitoring is a pattern of alert that can allow treatments capable of avoiding irreversible neurological deterioration.

AB - This paper examines the nitrogen isotope fractionation factors (alpha) associated with the volatilisation of ammonia from water under controlled conditions at two pH values (8.5 and 9.2). This experiment assumed the continuous removal of ammonia at a single purge rate of 10 mL air min-1. The fractionation resulting from the removal of total ammonia from the water into an acid trap was named the observed isotope fractionation factor (alphaobs), and it was measured as 1.019 (+/-0.0025) at pH 8.5 and 1.030 (+/-0.0025) at pH 9.2. The observed isotope fractionation factor includes the equilibrium isotope fractionation factor (alphaeq) and the kinetic isotope fractionation factor (alphakin), each one mathematically derived from the experimental data. The equilibrium and kinetic isotope fractionation factors were estimated as alphaeq = 1.036 (+/-0.0014) and alphakin = 1.050 (+/-0.003), respectively. Our results are compared to other previously measured and estimated fractionation factors. PMID- 30280593 TI - One-Stage Metatarsal Interposition Lengthening With an Autologous Fibula Graft for Treatment of Brachymetatarsia. AB - OBJECTIVE: Brachymetatarsia is defined as the pathological shortening of a metatarsal bone, which can cause cosmetic problems and pain in the forefoot. The main surgical treatment options are: extension osteotomy, interposition of a bone graft, and callus distraction. Usually, a bone graft from the iliac crest is used for the interposition osteotomy. The operative technique of graft extraction from the fibula has not been described in the literature yet. METHODS: Eight feet with brachymetatarsia in 5 patients were evaluated retrospectively. The minimum follow up period was 2 years. Via a dorsal V/Y skin incision, a central osteotomy on the metatarsal bone was done. A graft was obtained from the anterior fibula. The graft was inserted and fixed by a locking plate. Additional soft tissue procedures were done. RESULTS: We had bony consolidation in all cases. The mean extension was 9.01 mm (5.49 to 12.54 mm). This corresponded to a mean 20.3% extension of the entire metatarsal. High patient satisfaction as well as high satisfaction regarding the cosmetic results were achieved. There were no postoperative complications. The range of motion of the metatarsal-phalangeal joint IV was 20% less preoperative in terms of plantar flexion. Standing up on tiptoes was possible in all patients postoperatively. One patient reported mild symptoms after sports activities. CONCLUSIONS: Because of its anatomy the graft adapts to the metatarsal IV bone. As our study showed, harvesting from the distal fibula causes no functional restriction. In terms of wound and bone healing as well as pain symptoms, this method should be considered as an alternative to the standard iliac graft. PMID- 30280594 TI - The efficacy of "IOL-Vip Revolution" telescopic intraocular lens in age-related macular degeneration cases with senile cataract. AB - PURPOSE: To evaluate the efficacy of the IOL-Vip Revolution telescopic intraocular lens in age-related macular degeneration patients. METHODS: A total of 13 eyes of 12 age-related macular degeneration patients with senile cataract were enrolled. Selection of the patients was done by means of a low vision diagnostic and rehabilitative program (IOL-Vip software) that evaluates residual visual function. After standard phacoemulsification surgery, the incision site was enlarged and the IOL-Vip Revolution system was implanted in the capsular bag. The outcome measures were best corrected visual acuity, contrast sensitivity, anterior chamber depth, endothelial cell density, central corneal thickness, and quality-of-life questionnaire. RESULTS: The mean age of the subjects was 72.3 +/- 8.5 years. The mean positive power of the intraocular lens was 59 +/- 2 D and the negative intraocular lens power was standard (-46 D). Pre- and postoperative best corrected visual acuity were 1.08 +/- 0.14 and 0.81 +/- 0.16 logMAR in the operated eye and 1.13 +/- 0.36 and 1.01 +/- 0.40 logMAR in the unoperated eye, respectively. The best corrected visual acuity was increased significantly in both operated and unoperated eyes (p = 0.005 and 0.021, respectively). Quality of life and anterior chamber depth increased significantly (p = 0.018 and 0.008, respectively), while endothelial cell density decreased (p = 0.002). No significant differences were detected in central corneal thickness or contrast sensitivity (p = 0.133 and 0.684, respectively). CONCLUSION: The results showed that IOL-Vip Revolution telescopic intraocular lens is a promising treatment option in age-related macular degeneration patients. The rehabilitation program may have an important role in the restored clinical results, which also provided visual improvement in the unoperated eyes. PMID- 30280595 TI - Altered Functional Connectivity of Alpha Rhythm in Obsessive-Compulsive Disorder During Rest. AB - Obsessive-compulsive disorder (OCD) is a common inheritable psychiatric disorder characteristic of repetitive thinking, imagination (obsession), and stereotyped behaviors (compulsive). To explore whether there is an alteration of brain functional connectivity (BFC) in patients with OCD during rest, electroencephalogram (EEG) data of healthy controls (HCs) and patients with OCD were collected during rest in both eyes-closed and eyes-open states. Synchronization likelihood and graph theory were applied to construct and analyze brain functional networks of patients with OCD and HCs. Patients with OCD showed abnormal graph-theoretic parameters and impaired small world features in the alpha and beta bands. In addition, the topological analysis consistently showed that the long-range BFC of alpha rhythm was significantly reduced in the bilateral posterior areas in patients with OCD in comparison with HCs, while the BFC in the beta rhythm was significantly increased only in the eyes-open state. The findings suggest that the BFC of patients with OCD show abnormal small-world features and altered topological structure during rest, mainly in alpha and beta bands, which may provide a new insight for the diagnosis and treatment of OCD. PMID- 30280597 TI - Periarterial fat from two human vascular beds is not a source of aldosterone to promote vasoconstriction. AB - Mouse adipocytes have been reported to release aldosterone and reduce endothelium dependent relaxation. It is unknown if perivascular adipose tissue (PVAT) releases aldosterone in humans. The present experiments were designed to test the hypothesis that human PVAT releases aldosterone and induces endothelial dysfunction. Vascular reactivity was assessed in human internal mammary and renal segmental arteries obtained at surgery. The arteries were prepared with/without PVAT and changes in isometric tension were measured in response to the vasoconstrictor thromboxane prostanoid (TP) receptor agonist U46619 and the endothelium-dependent vasodilator acetylcholine. The effects of exogenous aldosterone and of MR antagonist eplerenone were determined. Aldosterone concentrations were measured by ELISA in conditioned media incubated with human adipose tissue with/without angiotensin II stimulation. Presence of aldosterone synthase and MR mRNA was examined in perirenal, abdominal and mammary PVAT by PCR. U46619-induced tension and acetylcholine-induced relaxation were unaffected by exogenous and endogenous aldosterone (addition of aldosterone and MR blocker) in mammary and renal segmental arteries, both in the presence and absence of PVAT. Aldosterone release from incubated perivascular fat was not detectable. Aldosterone synthase expression was not consistently observed in human adipose tissues in contrast to that of MR. Thus, exogenous aldosterone does not affect vascular reactivity and endothelial function in ex vivo human arterial segments and the tested human adipose tissues have no capacity to synthesize/release aldosterone. In perspective, physiologically relevant effects of aldosterone on vascular function in humans are caused by systemic aldosterone originating from the adrenal gland.

PMID- 30280598 TI - Dicer deficiency in proximal tubules exacerbates renal injury and tubulointerstitial fibrosis and upregulates Smad2/3. AB - Renal fibrosis is a common pathological feature in chronic kidney disease (CKD), including diabetic kidney disease (DKD) and obstructive nephropathy. Multiple microRNAs have been implicated in the pathogenesis of both DKD and obstructive nephropathy although the overall role of microRNAs in tubular injury and renal fibrosis in CKD is unclear. Dicer (a key RNase III enzyme for microRNA biogenesis) was specifically ablated from kidney proximal tubules in mice via the Cre/lox system to deplete micoRNAs. Proximal tubular Dicer knockout (PT- Dicer KO) mice and wild-type (WT) littermates were subjected to streptozotocin (STZ) treatment to induce DKD or unilateral ureteral obstruction (UUO) to induce obstructive nephropathy. Renal hypertrophy, renal tubular apoptosis, kidney inflammation, and tubulointerstitial fibrosis were examined. Comparing to WT mice, PT- Dicer KO mice showed more severe tubular injury and renal inflammation following STZ treatment. These mice also developed higher levels of tubolointerstitial fibrosis. Meanwhile, PT- Dicer KO mice had a significantly higher Smad2/3 expression in kidneys than WT mice (6 months of age) in both control and STZ treated mice. Similarly, UUO induced more severe renal injury, inflammation, and interstitial fibrosis in PT- Dicer KO mice than WT. Although we did not detect obvious Smad2/3 expression in sham-operated mice (2-3 months old), significantly more Smad2/3 was induced in obstructed PT- Dicer KO kidneys. These results supported a protective role of microRNA synthesis in renal injury and fibrosis development in CKD, specifically in DKD and obstructive nephropathy. Depletion of Dicer and microRNAs may up-regulate Smad2/3 related signaling pathway to enhance the progression of CKD. PMID- 30280599 TI - Skeletal muscle fibrosis is associated with decreased muscle inflammation and weakness in patients with chronic kidney disease. AB - Muscle dysfunction is an important cause of morbidity among patients with chronic kidney disease (CKD). Although muscle fibrosis is present in a CKD rodent model, its existence in humans and its impact on physical function are currently unknown. We examined isometric leg extension strength and measures of skeletal muscle fibrosis and inflammation in vastus lateralis muscle from CKD patients (n=10) and healthy, sedentary controls (n=10). Histochemistry and immunohistochemistry were used to assess muscle collagen and macrophage and fibro/adipogenic progenitor (FAP) cell populations, and RT-qPCR was used to assess muscle-specific inflammatory marker expression. Muscle collagen content was significantly greater in CKD compared with control (18.8 +/- 2.1% vs. 11.7 +/ 0.7% collagen area, p=0.008), as was staining for collagen I, pro-collagen I, and a novel collagen-hybridizing peptide that binds remodeling collagen. Muscle collagen was inversely associated with leg extension strength in CKD (r= -0.74, p=0.01). FAP abundance was increased in CKD, was highly correlated with muscle collagen (r=0.84, p<0.001), and was inversely associated with TNF-alpha expression (r= -0.65, p=0.003). TNF-alpha, CD68, CCL2, and CCL5 mRNA were significantly lower in CKD than control, despite higher serum TNF-alpha and IL-6. Immunohistochemistry confirmed fewer CD68+ and CD11b+ macrophages in CKD muscle. In conclusion, skeletal muscle collagen content is increased in humans with CKD and is associated with functional parameters. Muscle fibrosis correlated with increased FAP abundance, which may be due to insufficient macrophage-mediated TNF alpha secretion. These data provide a foundation for future research elucidating the mechanisms responsible for this newly identified human muscle pathology. PMID- 30280600 TI - Arginine reprogramming in ADPKD results in arginine-dependent cystogenesis. AB - Research into metabolic reprogramming in cancer has become commonplace, yet this area of research has only recently come of age in nephrology. In light of the parallels between cancer and ADPKD, the latter is currently being studied as a metabolic disease. In clear cell renal cell carcinoma (RCC), which is now considered a metabolic disease, we and others have shown derangements in the enzyme arginosuccinate synthase (ASS1) resulting in RCC cells becoming auxotrophic for arginine and leading to a new therapeutic paradigm involving reducing extracellular arginine. Based on our earlier finding that glutamine pathways are reprogrammed in ARPKD, and given the connection between arginine and glutamine synthetic pathways via citrulline, we investigated the possibility of arginine reprogramming in ADPKD. We now show that, in a remarkable parallel to RCC, ASS1 expression is reduced in murine and human ADPKD, and arginine depletion results in a dose dependent compensatory increase in ASS1 levels as well as decreased cystogenesis in vitro and ex vivo with minimal toxicity to normal cells. Non-targeted metabolomics analysis of mouse kidney cell lines grown in arginine-deficient vs. arginine-replete media suggests arginine-dependent alterations in the glutamine and proline pathways. Thus, depletion of this conditionally-essential amino acid by dietary or pharmacological means, such as with arginine-degrading enzymes, may be a novel treatment for this disease. PMID- 30280602 TI - Beyond the microscope: interpreting renal biopsy findings in the era of precision medicine. AB - As rapid progress in science and biotechnology is affecting the practice of renal medicine, increasingly precise diagnostic assessment is needed to select the most effective therapeutic approach for individual patients. The kidney biopsy remains the gold standard for the diagnosis of renal disease, but the field of renal pathology is evolving, classification of renal parenchyma lesions and histopathological diagnostic criteria are undergoing more validation and updates, and new technologies and assays are sought to improve efficiency and accuracy of the diagnostic process. How new knowledge and scientific advances may potentially affect renal pathology is discussed. PMID- 30280601 TI - Anti-C5a complementary peptide mitigates zymosan-induced severe peritonitis with fibrotic encapsulation in rat pretreated with methylglyoxal. AB - In a previous study of fungal peritoneal injury in peritoneal dialysis (PD) patients, complement (C)-dependent pathological changes were developed in zymosan (Zy)-induced peritonitis by peritoneal scraping. However, the injuries were limited to the parietal peritoneum and did not show any fibrous encapsulation of the visceral peritoneum, which differs from human encapsular peritoneal sclerosis (EPS). We investigated peritoneal injury in a rat model of Zy-induced peritonitis pretreated with methylglyoxal instead of scraping (Zy/MGO peritonitis) to clarify the role of C in the process of fibrous encapsulation of the visceral peritoneum. Therapeutic effects of an anti-C5a complementary peptide, AcPepA, on peritonitis were also studied. In Zy/MGO peritonitis, peritoneal thickness, fibrin exudation, accumulation of inflammatory cells, and deposition of C3b and C5b-9 with loss of membrane C regulators were increased along the peritoneum until day 5. On day 14, fibrous encapsulation of the visceral peritoneum was observed, resembling human EPS. Peritoneal injuries and fibrous changes were significantly improved with AcPepA treatment, even when AcPepA was administered following injection of Zy in Zy/MGO peritonitis. The data show that C5a might play a role in the development of encapsulation-like changes in the visceral peritoneum in Zy/MGO peritonitis. AcPepA might have therapeutic effects in fungal infection-induced peritoneal injury by preventing subsequent development of peritoneal encapsulation. PMID- 30280603 TI - Variations of perceived load and well-being between normal and congested weeks in elite case study handball team. AB - The aim of this study was two-fold: (i) to analyze the variations in internal load and well-being in professional handball players between normal and congested weeks and (ii) to analyze the variations between training days within weeks. Twenty male players (26.5 +/- 4.9 yo) were monitored during a full season. MD-1 (match day -1) revealed larger decreases in muscle soreness (-17.3%, [-26.6; 6.9]) and fatigue (-16.6%, [-24.8;-7.4]) in congested weeks. Regarding MD-2, larger decreases in DOMS (-19.9%, [-30.5;-7.6]), fatigue (-19.7%, [-30.0;-7.9] and the Hooper index (-16.7%, [-25.6;-6.7]) were found in congested weeks. The results of this study reveal that larger variations between normal and congested weeks occurred in MD-2 and MD-3, with greater values of load and lower levels of well-being occurring in normal weeks. Within-weeks changes revealed greater loads occurring on MD-3 and MD-2 in comparison to MD-1; in the opposite way, greater values of muscle soreness and fatigue occurred on MD-1. PMID- 30280604 TI - Prospective evaluation of anesthetic protocols during pediatric ophthalmic surgery. AB - PURPOSE: To date, no protocol of anesthesia for pediatric ophthalmic surgery is unanimously recognized. The primary anesthetic risks are associated with strabismus surgery, including oculocardiac reflex, postoperative nausea and vomiting, and postoperative pain. METHODS: This was a prospective, monocentric, observational study conducted in a tertiary pediatric ophthalmic unit. Our anesthetic protocol for strabismus surgery included postoperative nausea and vomiting prevention using dexamethasone and ondansetron. No drug-based prevention of oculocardiac reflex or local/locoregional anesthesia was employed. RESULTS: A total of 106 pediatric ophthalmic surgeries completed between November 2015 and May 2016 were analyzed. The mean patient age was 4.4 (range: 0.2-7.3, standard deviation: 2.4) years. Ambulatory rate was 90%. Oculocardiac reflex incidence was 65% during strabismus surgery (34/52), 50% during congenital cataract surgery (4/8), 33% during intramuscular injection of botulinum toxin (1/3), and 0% during other procedures. No asystole occurred. Postoperative nausea and vomiting incidence was 9.6% after strabismus surgery (5/52) and 0% following the other procedures. One child was hospitalized for one night because of persistent postoperative nausea and vomiting. Postoperative pain generally occurred early on in the recovery room and was quickly controlled. Its incidence was higher in patients who underwent strabismus surgery (27%) than in those who underwent other procedures (9%). CONCLUSION: Morbidity associated with ophthalmic pediatric surgery is low and predominantly associated with strabismus surgery. The benefit risk ratio and cost-effectiveness of oculocardiac reflex prevention should be questioned. Our postoperative nausea and vomiting rate is low, thanks to the use of a well-managed multimodal strategy. Early postoperative pain is usually well treated but could probably be more effectively prevented. PMID- 30280605 TI - Foraging Behavior Patterns of Sheep and Horses Under a Mixed Species Grazing System. AB - The research objective was to assess the behavior patterns of the Polish Konik horse breed and the Uhruska variety of the Polish Lowland Sheep breed under a mixed-grazing system, and their relationship with climatic factors. The observation included 4 adult horses, 27 ewes with lambs and 10 primiparous ewes. The behavior of the animals and the weather conditions were recorded at 60-min intervals. Horses and sheep displayed similarities in both species-specific behavioral patterns and timing of grazing activity, and the duration of foraging sessions was mostly influenced by time of day, lower temperature and relative humidity. In addition, the two species showed more interest in the watering place in the afternoon, and drinking frequency was mainly dependent on air temperature. The animals that pastured together gradually began to mix, but at first, they remained within their species group. Both animal species can be used for environmental protection and landscape conservation making rational use of pastures within protected areas. PMID- 30280607 TI - Animal Welfare in Nepal. AB - The small densely populated country of Nepal rises from just above sea level to more than 8800 m and encompasses many agro-ecological zones. Rich in both nature and culture, livestock are integral to household and national economies. Most Nepalese consider the cow sacred, and slaughter is forbidden. Other nonhuman animals are less esteemed, slaughter is not proscribed, and many are sacrificed during religious festivals. Limited financial and material resources, inadequate feed supplies, poor access to veterinary services, absence of appropriate legislation, and ignoring the needs of livestock as sentient beings can compromise welfare and lead to inhumane treatment. This article reviews the welfare status of various groups (food-producing stock, work animals, street dogs, experimental animals, and elephants in captivity). Several animal welfare charities are represented. Suggestions for improved welfare are discussed, but the prognosis is not encouraging especially in view of the widespread struggle and people's own struggle for survival. PMID- 30280606 TI - Assessing the Feasibility of Measuring Variation in Facility Design Among American Childbirth Facilities. AB - OBJECTIVE: To assess the feasibility of quantifying variation in childbirth facility design and explore the implications for childbirth service delivery across the United States. BACKGROUND: Design has been shown to impact quality of care in childbirth. However, most prior studies use qualitative data to examine associations between the design of patient rooms and patient experience. There has been limited exploration of measures of unit design and its impact on care provision. METHOD: We recruited 12 childbirth facilities that were diverse with regard to facility type, location, delivery volume, cesarean delivery rate, and practice model. Each facility provided annotated floor plans and participated in a site visit or telephone interview to provide information on their design and clinical practices. These data were analyzed with self-reported primary cesarean delivery rates to assess associations between design and care delivery. RESULTS: We observed wide variation in childbirth unit design. Deliveries per labor room per year ranged from 75 to 479. The ratio of operating rooms to labor rooms ranged from 1:1 to 1:9. The average distance between labor rooms and workstations ranged from 23 to 114 ft, and the maximum distance between labor rooms ranged from 9 to 242 ft. More deliveries per room, fewer labor rooms per operating room, and longer distances between spaces were all associated with higher primary cesarean delivery rates. CONCLUSIONS: Clinically relevant differences in design can be feasibly measured across diverse childbirth facilities. The design of these facilities may not be optimally matched to service delivery needs. PMID- 30280608 TI - Oral insulin delivery by carboxymethyl-beta-cyclodextrin-grafted chitosan nanoparticles for improving diabetic treatment. AB - In this paper, a new oral insulin formulation, insulin-loaded carboxymethyl-beta cyclodextrin-grafted chitosan nanoparticles (insulin/CMCD-g-CS NPs), was fabricated by ionic crosslinking technique. The therapeutic efficacy of new formulation was investigated in detail. Firstly, the CMCD-g-CS was synthesized by EDC-mediated esterification reaction. The prepared CMCD-g-CS exhibited favourable loading capacity and encapsulation efficiency of drug. The release experiment in vitro showed that the nanocarrier could efficiently protect encapsulated insulin at simulated gastric environment and release drug in the simulated colonic fluid. The insulin/CMCD-g-CS NPs effectively promoted drug internalization into Caco-2 cells and could reversibly open the tight junction between cells. The oral administration of insulin/CMCD-g-CS NPs could lastingly decrease blood sugar level in diabetic mice. The liver function study verified that the insulin/CMCD-g CS NPs had not obvious toxicity to experimental mice. Therefore, the CMCD-g-CS could be an effective and safe oral insulin delivery carrier for future clinical application. [Formula: see text] A new biocompatible polysaccharide nanoparticle was fabricated as oral insulin delivery carrier for improving diabetic treatment. PMID- 30280610 TI - STAT1 and STAT3 mutations: important lessons for clinical immunologists. AB - INTRODUCTION: The transcription factors signal transducer and activator of transcription (STAT) 1 and STAT3 fulfill fundamental functions in nonimmune and immune cells. The description and follow-up of patients with germline mutations that result in either loss-of-function or gain-of-function have contributed to our understanding of the pathophysiology of these regulators. Depending on the type of mutations, clinical symptoms are complex and can include infection susceptibility, immune dysregulation as well as characteristic nonimmune features. Areas covered: In this review, we provide an overview about mechanistic concepts, clinical manifestations, diagnostic process, and traditional as well as innovative treatment options aiming to help the clinical immunologist to better understand and manage these complex and rare diseases. Clinical and research papers were identified and summarized through PubMed Internet searches, and expert opinions are provided. Expert commentary: The last several years have seen an explosion in the clinical descriptions and pathogenesis knowledge of the diseases caused by GOF and LOF mutations in STAT1 and STAT3. However, harmonization of laboratory testing and follow-up in international cohorts is needed to increase our knowledge about the natural history of these disorders as well as the development of curative or supportive targeted therapies. PMID- 30280609 TI - Decoding cold ischaemia time impact on kidney graft: the kinetics of the unfolded protein response pathways. AB - The relationship between cold ischaemia time (CIT) and adverse outcome is now acknowledged. However, the underlying mechanisms remain to be defined, which slows the development of adapted therapeutics and diagnostics. We explored the impact of CIT in both preclinical and in vitro models of preservation. We determined that the endoplasmic reticulum (ER) and its stress response (unfolded protein response, UPR) were regulated in close association with CIT; the eIF2alpha-ATF4 pathway was inhibited early (1-8 h) at the detriment of cell survival, while the ATF6 pathway was activated late (12-24 h) and associated with cell death. The IRE1alpha-XBP1 branch was activated at reperfusion only if CIT extended beyond 8 h, and had a dual role on cell fate - deleterious through IRE1's RNase activity and beneficial through IRE1alpha other roles. Finally, the pro-apoptotic factor CHOP was a common target of both ATF6 and IRE1alpha pathways and was associated with elongated CIT and increased cell death. Microarray analysis of human transplanted kidney confirmed that UPR markers were regulated by CIT and that CHOP was associated with adverse outcome. We show that UPR could be a critical pathway explaining the relationship between CIT and graft outcome, highlighting the potential for UPR-based therapeutics and diagnostics to improve transplantation. PMID- 30280611 TI - Is exposure to personal music players a confounder in adolescent mobile phone use and hearing health studies? AB - OBJECTIVE: This study was performed to determine whether exposure to personal music players (PMPs) in the immediate morning prior to hearing testing confounds the association between mobile phone use and hearing thresholds of adolescents. DESIGN: In this cohort study of cognitive function in year 7 students (median age 13 years, range 11-14), information regarding the weekly use of mobile phones and the use of PMPs was assessed by a questionnaire. Pure-tone audiometry was used to establish hearing thresholds for all participants. RESULTS: Among a cohort of 317 adolescents (60.9% females), 130 were unexposed to PMP use while 33 were exposed to PMP use in the morning prior to hearing testing. No statistically significant difference in hearing threshold shifts was found between adolescents who were and were not exposed to PMP use prior to hearing testing. Likewise, the difference in the use of mobile phones according to the PMP use status was not statistically significant. CONCLUSION: Exposure to PMPs prior to hearing testing did not introduce confounding in the present study of mobile phone use and hearing loss among adolescents. PMID- 30280612 TI - Effect of progesterone/estradiol ratio on pregnancy outcome of patients with high trigger-day progesterone levels undergoing gonadotropin-releasing hormone antagonist intracytoplasmic sperm injection cycles: a retrospective cohort study. AB - This study investigates the predictive power of serum progesterone/estradiol (P/E2) level for estimating the live birth rate in patients who had a serum progesterone (P) rate >= 1.5 ng/mL on the human chorionic gonadotropin (hCG) administration day and who received the gonadotropin-releasing hormone (GnRH) antagonist protocol and intracytoplasmic sperm injection (ICSI). This retrospective cohort study included 176 cycles. The P/E2 ratio was lower in patients with a live birth (0.73 +/- 0.54) than those without a live birth (1.05 +/- 1.38), but the difference was not statistically significant (p = .158). According to the receiver operating characteristic curve analysis of the hCG day P/E2 ratio, the area under the curve was 0.579 (95% confidence interval: 0.478 - 0.680, p = .158) for predicting live birth. In conclusion, this study suggests that a P/E2 ratio is not a significant predictor of a live birth rate in the patients with an hCG-day serum progesterone level of >=1.5 ng/mL undergoing GnRH antagonist ICSI cycles with a fresh embryo transfer. Impact statement What is already known on this subject? As the progesterone (P) levels in the late follicular phase correlate with the estradiol (E2) levels and the increase in mature follicles, earlier studies have proposed the trigger-day progesterone/estradiol (P/E2) ratio as a potential new marker for a premature luteinisation and live birth success. Most of these studies were conducted on long agonist cycles, and found that arbitrarily defined P/E2 ratio of >1 to be associated with poor pregnancy outcomes. What do the results of this study add? This study retrospectively examines the gonadotropin-releasing hormone (GnRH) antagonist cycles with a trigger-day serum P value of >=1.5 ng/mL undergoing the intracytoplasmic sperm injection (ICSI) treatment. The receiver operating characteristic (ROC) curve analysis did not identify a statistically significant threshold value for the trigger-day P/E2 ratio that was beneficial in predicting a live birth. The P/E2 ratio was also lower in the cycles with a live birth than those without a live birth, although the difference was not statistically significant. What are the implications of these findings for clinical practice and/or further research? The trigger-day P/E2 ratio does not seem to be an efficient prognostic factor for a live birth in the GnRH antagonist ICSI cycles with a trigger-day serum progesterone level of >=1.5 ng/mL. Further studies are needed to clarify the association of the trigger-day P/E2 ratio and the pregnancy outcomes in GnRH antagonist ICSI cycles.

AB - : With a common goal of increasing social inclusion through collaboration between the mental health and recreation sectors, the Recreation for Mental Health Project was a partnership between Dalhousie University, Recreation Nova Scotia, and the local Canadian Mental Health Association branch. AIMS: Central to this project was the meaningful involvement of individuals with First Voice perspectives-in this case, people with lived experience of mental health challenges. This paper describes key strategies used to privilege First Voice perspectives throughout this project. METHODS: The strategies included (a) advisory committee membership, (b) arts-based activities, (c) community-based research, and (d) co-leadership in project dissemination. FINDINGS AND CONCLUSION: Initial strategies related to the project's overall direction and research activities culminated in shared dissemination activities that fostered co-leadership. This co-leadership created the opportunity to intentionally discuss the challenges and facilitators of partnerships between people with First Voice experience and researchers throughout the project. SIGNIFICANCE: This intentional process of exploring multiple perspectives bridged notions of 'us' and 'them', cultivating a sense of solidarity across shared experiences of exclusion and agency. Key principles related to relationships, multiple identities, and power-sharing are synthesized. PMID- 30280614 TI - Economic evaluation of a pharmacogenomic multi-gene panel test to optimize anti hypertension therapy: simulation study. AB - AIMS: Hypertension is the strongest modifiable risk factor for cardiovascular disease, affecting 80 million individuals in the US and responsible for ~360,000 deaths, at total annual costs of $93.5 billion. Antihypertension therapies guided by single genotypes are clinically more effective and may avert more adverse events than the standard of care of layering anti-hypertensive drug therapies, thus potentially decreasing costs. This study aimed to determine the economic benefits of the implementation of multi-gene panel guided therapies for hypertension from the payer perspective within a 3-year time horizon. MATERIALS AND METHODS: A simulation analysis was conducted for a panel of 10 million insured patients categorized clinically as untreated, treated but uncontrolled, and treated and controlled over a 3-year treatment period. Inputs included research data; empirical data from a 11-gene panel with known functional, heart, blood vessel, and kidney genotypes; and therapy efficacy and safety estimates from literature. Cost estimates were categorized as related to genetic testing, evaluation and management, medication, or adverse events. RESULTS: Multi-gene panel guided therapy yielding savings of $6,256,607,500 for evaluation and management, $908,160,000 for medications, and $37,467,508,716 for adverse events, after accounting for incremental genetic testing costs of $2,355,540,000. This represents total 3-year savings of $42,276,736,216, or a 47% reduction, and 3 year savings of $4,228 and annual savings of $1,409 per covered patient. CONCLUSIONS: A precision medicine approach to genetically guided therapy for hypertension patients using a multi-gene panel reduced total 3-year costs by 47%, yielding savings exceeding $42.3 billion in an insured panel of 10 million patients. Importantly, 89% of these savings are generated by averting specific adverse events and, thus, optimizing choice of therapy in function of both safety and efficacy. PMID- 30280615 TI - Development of the Pediatric Disability Inventory-Patient Reported Outcome (PEDI PRO) measurement conceptual framework and item candidates. AB - BACKGROUND: To address the gap in patient reported outcome measures (PROMs) of functional performance appropriate for youth and young adults with developmental disabilities (DD) we developed the Pediatric Evaluation of Disability Inventory Patient Reported Outcome (PEDI-PRO). AIM/OBJECTIVE: We used a participatory process to: (1) Develop the measurement conceptual framework; (2) Identify discrete functional tasks to include in the PEDI-PRO; and (3) Refine item candidates. METHODS: We collaborated with eight youth with DD over 33 months. These youth and university researchers explored the construct of functional performance, developed and refined items, and collected and analyzed data. We also conducted focus groups with youth with DD (n = 62) and rehabilitation professionals (n = 26), and consulted with PEDI measurement experts (n = 3). RESULTS: Youth's understanding of their functional performance is embedded in their experiences participating in everyday life situations. We developed 78 Daily Activities, 65 Social/Cognitive, and 52 Mobility item candidates that are linked to 11 everyday life situations to assess discrete functional tasks important to youth with DD and rehabilitation professionals. CONCLUSION AND IMPLICATIONS: As a result of our participatory development process, the PEDI PRO's proposed conceptual framework and item candidates are grounded in the lived experience of youth with DD. PMID- 30280616 TI - Metabolic syndrome is associated to high-sensitivity cardiac troponin T elevation. AB - INTRODUCTION: Metabolic syndrome (MetS) and high-sensitivity cardiac troponin T (hs-TnT) are associated with higher risk for cardiovascular diseases (CVD). Our aim was to assess the relation between hs-TnT elevation and MetS in a general population sample. MATERIALS AND METHODS: Individuals participating in an annual health survey program between 2010 and 2016 were included in the study. Blood samples including hs-TnT levels were collected. The study population was divided into three groups based on hs-TnT levels - undetectable (<5 ng/L), intermediate (5-14 ng/L) and elevated (>14 ng/L). RESULTS: A total of 5994 subjects were included in the study, the mean age was 48.5 and 4336 (72%) were males. Compared with subjects with undetectable hs-TnT the prevalence of MetS was higher in those with detectable and elevated levels - 392 (10%) vs. 270 (15%) and 51 (33%), respectively (p < 0.001). In a multivariate model adjusted for age, gender and multiple co-morbidities, the number of MetS components and presence of MetS were significantly associated with an increased risk for detectable hs-TnT levels (OR = 1.02 {for each component}; 95% CI [1.00-1.05], p = 0.04) and (OR = 1.13; 95% CI [1.07-1.2], p < 0.001) respectively. Only the waist, glucose and hypertension components of the MetS were significantly associated with elevated troponin. CONCLUSIONS: The MetS and its distinct components have a cumulative impact on hs TnT levels in apparently healthy subjects. PMID- 30280617 TI - A discrete choice experiment to investigate patient preferences for HIV testing programs in Bogota, Colombia. AB - BACKGROUND: To assess patients' preferences for HIV testing in Colombia. METHODS: A discrete choice experiment was used to assess preferences of patients diagnosed with HIV, for HIV testing in two HIV clinics in Bogota, Colombia. Patients were asked to choose repeatedly between two hypothetical HIV testing options that varied with respect to five attributes: distance to testing site, confidentiality, testing days, sample collection method, and the services if HIV positive. A random parameter model was used to analyze the data. RESULTS: A total of 249 questionnaires were eligible for data analysis. Respondents showed a preference for testing on weekdays, nobody being aware, a sample taken from the arm, and receiving medications through a referral. The respondents showed a high negative preference for many people being aware, followed by testing during the weekend and home testing. Subgroup analyses by gender and prior testing history did not reveal significant differences. CONCLUSION: This study suggests that patients' preferences for HIV testing focused especially on confidentiality, availability during weekdays, and using a sample from the arm. This information could be useful to improve uptake of HIV testing in Bogota, Colombia. PMID- 30280618 TI - Stereotactic body radiation therapy for mediastinal lymph node metastases: how do we fly in a 'no-fly zone'? AB - PURPOSE: To evaluate the treatment-induced toxicity (as primary endpoint) and the efficacy (as secondary endpoint) of stereotactic body radiation therapy (SBRT) in the treatment of mediastinal lymph nodes (LNs) in the so-called no-fly zone (NFZ) in cancers with various histology. MATERIAL AND METHODS: Forty-two patients were retrospectively analyzed. Institutional dose/volume constraints for organs at risk (OARs) derived by published data were strictly respected. The correlation between treatment-related variables and toxicity was investigated by logistic regression, Chi-squared test or Fisher's exact test. Overall survival (OS), cause specific survival (CSS), progression-free survival (PFS) and local control (LC) were collected from the follow-up reports. The impact of potential predictive factors on LC, PFS and OS were estimated by Cox proportional-hazard regression. RESULTS: Median follow-up time was 16 months (range 1-41). Four patients had esophageal G1 toxicity. Ten and six patients had G1 and G2 pulmonary toxicity, respectively. Treatment site and irradiation technique were significantly correlated with G >= 2 and G >= 1 toxicity, respectively. OS probability at 19 months was 88.3% and corresponded to CSS. LC probability at 16 months was 66.3% (median LC duration: 22 months, range 1-41). Fifteen patients (35.7%) were disease-free at 25 months (median time, range 1-41). The biologically effective dose (BED) and the target dose coverage indexes were significantly correlated with LC. CONCLUSIONS: SBRT can be considered as a safe treatment option for selected patients with oligo-metastases/recurrences in the NFZ, if strict dose/volume constraints are applied. PMID- 30280619 TI - Disparities in colorectal cancer between Northern and SouthernSweden - a report from the new RISK North database. AB - BACKGROUND: Geographic cancer health disparities have been reported in Sweden. The disparities are not fully understood, but may be attributed to differences in exposure to risk factors as well as differences in health care, socioeconomics and demography. The aim of this study was to describe the new nationwide population based RISK North database and its potential by analysing health disparities in colorectal cancer between Northern and Southern Sweden. METHODS: Cancer-specific data from the National Cancer Quality Registers for colorectal, gastric and oesophageal cancer and brain tumours were linked to several nationwide registers hereby creating a new database - RISK North. To exemplify the potential of RISK North, we analyzed differences in colorectal cancer incidence, mortality and survival in relation to gender, age, cohabitation and education between Northern and Southern Sweden 2007-2013. RESULTS: In colon cancer, the age-adjusted incidence per 100.000 was lower in Northern than Southern Sweden, 35.9 in the North vs. 41.1 in the South (p < .01); mortality rates were 11.0 vs. 12.2 (p < .01). For rectal cancer, incidence rates were 17.6 vs. 19.7 (p < .01) and mortality rates 5.33 vs. 5.89 (p = .07), respectively. The largest difference in incidence was demonstrated for colon cancer among individuals >79 years old (190. vs. 237, i.e., ~20%). Survival in colon cancer was higher in Southern Sweden, HR 0.92 (0.87-0.98) adjusted for age, gender, co habiting, education and m-stage at diagnosis. No difference in survival was seen for rectal cancer. CONCLUSIONS: The new RISK North database enabled analysis of cancer disparities between Northern and Southern Sweden. The incidence of colorectal cancer were lower in the North of Sweden whereas colon cancer survival was higher in the South. These differences can be further analysed utilising the RISK North database. PMID- 30280620 TI - National practice patterns of proton versus photon therapy in the treatment of adult patients with primary brain tumors in the United States. AB - OBJECTIVES: To examine patterns of care associated with the administration of proton versus photon therapy for adult patients with primary brain tumors in a large national cohort from the United States. METHODS: The National Cancer Database (NCDB) was queried for newly diagnosed primary brain tumors (2004-2014) in adult patients aged 18 and older receiving proton or photon radiotherapy. Clinical features, patient demographics and treatment parameters were extracted. Differences between groups were assessed using multivariable logistic regression analysis. RESULTS: In total, 73,073 patients were analyzed (n = 72,635 [99.4%] photon therapy, n = 438 [0.6%] proton therapy). On multivariable analysis of photon versus proton therapy, several factors predicted for receipt of proton therapy, including younger age (p = .041), highest income quartile (p = .007), treatment at academic institutions (p < .001), in regional facilities outside the Midwest/South (p < .001), diagnosis in more recent years (p = .003), fewer comorbidities (p < .001) and non-glioblastoma histology (p < .001). CONCLUSIONS: There are several significant socioeconomic variables that influence receipt of proton therapy for primary brain tumors. Although not implying causation, the socioeconomic findings discovered herein should be taken into account when delivering cancer care to all patients. PMID- 30280621 TI - Everyday managing and living with autoimmune Addison's disease: Exploring experiences using photovoice methods. AB - People with rare diseases are a minority group that faces risks for healthcare and work inequities because knowledge and resources on how to systematically support health or working life are limited. Integrating voices of persons living with rare diseases are an important aspect in inclusive and relevant healthcare practices. This study sought to actively involve persons with autoimmune Addison's disease (AAD), a rare condition, in exploring challenges and possibilities situated in everyday life. Photovoice methods were utilized to incorporate experiences through photographic documentation and group discussions with five persons over seven weeks. Data generated from group sessions were visually analyzed or transcribed and analyzed with thematic analysis. Five themes emerged: Individual and fine tuning in everyday life; It is not how it was; The power of knowledge and support; Becoming the expert in an uncertain context; and, Finding balance and paving new ways. The findings showed that everyday life with AAD was more complex than earlier portrayed; entailing several barriers and negotiations. In order to meet the needs of persons with AAD, more extensive and relevant information, support and self-management education is needed. Moreover, a complementary focus on everyday life to promote their health and wellbeing is also important. PMID- 30280622 TI - Re-irradiation for painful bone metastases using stereotactic body radiotherapy. AB - PURPOSE: Stereotactic body radiotherapy (SBRT) is expected to achieve safe and effective re-irradiation for painful bone metastases. This study aimed to clarify the efficacy of re-irradiation using SBRT for painful bone metastases. METHODS: Prospective database at our institution for the period between September 2013 and December 2017 were retrospectively reviewed for patients with: (1) painful bone metastases; (2) history of radiotherapy to the metastasis; and (3) SBRT performed as re-irradiation. Pain response, pain failure-free duration, analgesics medications, and adverse events were evaluated. Pain was evaluated using the Numerical Rating Pain Score, and pain response was evaluated based on International Consensus Pain Response Endpoints. Best response during follow-up was noted. Patients with complete or partial response were defined as showing pain response, and patients with pain progression were defined as showing pain failure. Adverse events were evaluated based on the RTOG/EORTC Late Radiation Morbidity Scoring Schema. RESULTS: Sixty-six patients selected from our database showed: median age, 65 years (range, 33-82 years); ECOG performance status, 0 1/2/3/4, 51/10/3/2; lesion histopathology, rectal/lung/renal/thyroid/other cancer, 13/11/9/5/28; median previous irradiated dose, 30 Gy (range, 8-70.4 Gy); median interval from latest irradiation, 21 months (range, 4-192 months); prescribed dose for SBRT, 24 Gy in 2 fractions/30 Gy in 5 fractions/35 Gy in 5 fractions, 51/13/2. Median follow-up after SBRT was 10 months (range, 1-37 months). Fifty-seven patients achieved pain response (86%). The 1-year pain failure-free rate was 55%. Median pain failure-free duration was 13 months (range, 1-24 months). Grade 4 adverse events were observed in six patients (vertebral compression fracture, n = 5; radiation myelopathy, n = 1). No other toxicities of Grade 3 or greater were encountered. CONCLUSIONS: Re-irradiation SBRT has potential to achieve good response and long-term pain control for painful bone metastases. Prospective analysis is necessary to confirm the safety and efficacy of SBRT as re-irradiation. PMID- 30280623 TI - Dose painting for re-irradiation of head and neck cancer. AB - BACKGROUND: For patients with recurrent or second primary disease, re-irradiation can be challenging due to overlap with previously irradiated volumes. Dose painting may be attractive for these patients, as the focus is on delivering maximal dose to areas of high tumor activity. Here, we compare dose painting by contours (DPBC) treatment plans based on 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) with conventional plans. MATERIAL AND METHODS: We included 10 patients with recurrent or second primary head and neck cancer (HNC) eligible for re-irradiation. Our conventional re-irradiation regimen is hyperfractionated radiotherapy 1.5 Gy twice daily over 4 weeks, giving a total dose of 60 Gy. For DPBC, we defined two prescription volumes, PV33 and PV66, corresponding to 33 and 66% of the highest FDG uptake in the tumor. The clinical target volume (CTV) prescription dose was 60 Gy, PV33; 65-67 Gy and PV66; 70-73 Gy. The DPBC plan is to be given the first 20 fractions and the conventional plan the last 20 fractions. Dose to organs at risk (OARs) were compared for DPBC and conventional treatment. By summation of the initial curative plan and the re irradiation plan, we also evaluated differences in dose to the 2 ccm hot spot (D2cc). RESULTS: We achieved DPBC plans with adequate target coverage for all 10 patients. There were no significant differences in OAR doses between the standard plans and the DPBC plans (p=.7). Summation of the initial curative plan and the re-irradiation plan showed that the median D2cc increased from 130 Gy (range 113 132 Gy; conventional) to 140 Gy (range 115-145 Gy; DPBC). CONCLUSIONS: Our proposed DPBC could be straightforwardly implemented and all plans met the objectives. Re-irradiation of HNC with DPBC may increase tumor control without more side effects compared to conventional radiotherapy. PMID- 30280624 TI - Increasing kidney cancer incidence and survival in Estonia: role of age and stage. AB - BACKGROUND: Kidney cancer rates in Estonia are high. The study aimed to examine long-term trends in kidney cancer incidence, mortality and survival in Estonia, with special focus on age, birth cohorts, morphology and TNM stage. MATERIAL AND METHODS: Estonian Cancer Registry provided data on all incident cases of kidney cancer (ICD-10 C64), diagnosed in adults (age >=15 years) in Estonia during 1995 2014. Relative survival ratios (RSR) were calculated and excess hazard ratios of dying were estimated with gender, age, period of diagnosis and TNM stage as independent variables. Joinpoint regression modeling was used to calculate estimated annual percentage change for incidence (1970-2014) and mortality (1995 2016) trends. Age-specific incidence rates were presented by birth cohort and period of diagnosis. RESULTS: Incidence increased significantly in both sexes, with the steepest rise seen for localized cancer. Cohort effects were pronounced particularly in men, while period effects were seen from the mid-1980s to mid 1990s in both sexes. Age-standardized five-year RSR for total kidney cancer increased by 13 percentage units (from 53% to 65%) over the study period; the increase was larger for renal cell carcinoma (from 63% to 78%). Survival increases of about five percentage units were seen for stages I/II and III. Age and gender were not associated with excess risk of dying from renal cell carcinoma after adjusting for stage. CONCLUSION: Estonia is currently among countries with the highest incidence of kidney cancer. The results suggest a combined effect of changing risk profiles in successive birth cohorts and increasing diagnostic activity around 1990. Large survival increase can mostly be attributed to earlier detection, but improved diagnosis and treatment have probably influenced stage-specific survival. High proportion of tumors with unspecified morphology and those with unknown stage among the elderly warrants further investigation of diagnostic and treatment practices. PMID- 30280625 TI - Frailty status but not age predicts complications in elderly cancer patients: a follow-up study. AB - OBJECTIVES: The purposes were to investigate the health status of elderly cancer patients by comprehensive geriatric assessment (CGA) and to compare the complications with respect to baseline CGA and to evaluate the need for geriatric interventions in an elderly cancer patients' population. MATERIAL: Patients aged >=70 years with lung cancer (LC), cancer of the head and neck (HNC), colorectal cancer (CRC), or upper gastro-intestinal cancer (UGIC) are referred to the Department of Oncology for cancer treatment. METHODS: CGA was performed prior to cancer treatment and addressed the following domains: Activities of daily living (ADL), instrumental ADL (IADL), comorbidity, polypharmacy, nutrition, cognition, and depression. Complications, defined as dose reduction and discontinuation of treatment due to grade 3-4 toxicity, hospital admission, shift to palliative treatment, or death within 90 days, were identified from the medical files. Patients were classified as fit, vulnerable, or frail by CGA. PRINCIPAL RESULTS: Patients (N = 217) with a median age of 75 years (range: 70-93 yeas) were included: 13% were fit, 35% vulnerable, and 52% frail. CGA significantly predicted admittance to hospital in frail and vulnerable patients compared to fit patients: risk ratio (RR) 2.12 (95% CI: 1.01; 4.46). Vulnerable and frail patients had higher absolute risk of death within 90 days compared to fit patients: 7% and 23% versus 0%. HR for death within 90 days in frail patients as compared to vulnerable patients was 3.50 (95% CI: 1.34; 9.15). More frail patients (88%) needed geriatric interventions than the vulnerable (46%) and fit patients (32%). Major conclusion: Few elderly cancer patients seem to be fit. CGA predicts admittance to hospital in a population of elderly patients with mixed cancer diseases. Frail and vulnerable patients have higher risk of death within 90 days as compared to fit patients. PMID- 30280626 TI - Comparative treatment planning study for mediastinal Hodgkin's lymphoma: impact on normal tissue dose using deep inspiration breath hold proton and photon therapy. AB - BACKGROUND: Late effects induced by radiotherapy (RT) are of great concern for mediastinal Hodgkin's lymphoma (HL) patients and it is therefore important to reduce normal tissue dose. The aim of this study was to investigate the impact on the normal tissue dose and target coverage, using various combinations of intensity modulated proton therapy (IMPT), volumetric modulated arc therapy (VMAT) and 3-dimensional conformal RT (3D-CRT), planned in both deep inspiration breath hold (DIBH) and free breathing (FB). MATERIAL AND METHODS: Eighteen patients were enrolled in this study and planned with involved site RT. Two computed tomography images were acquired for each patient, one during DIBH and one during FB. Six treatment plans were created for each patient; 3D-CRT in FB, 3D-CRT in DIBH, VMAT in FB, VMAT in DIBH, IMPT in FB and IMPT in DIBH. Dosimetric impact on the heart, left anterior descending (LAD) coronary artery, lungs, female breasts, target coverage, and also conformity index and integral dose (ID), was compared between the different treatment techniques. RESULTS: The use of DIBH significantly reduced the lung dose for all three treatment techniques, however, no significant difference in the dose to the female breasts was observed. Regarding the heart and LAD doses, large individual variations were observed. For VMAT, the mean heart and LAD doses were significantly reduced using DIBH, but no significant difference was observed for 3D-CRT and IMPT. Both IMPT and VMAT resulted in improved target coverage and more conform dose distributions compared to 3D-CRT. IMPT generally showed the lowest organs at risk (OAR) doses and significantly reduced the ID compared to both 3D-CRT and VMAT. CONCLUSIONS: The majority of patients benefited from treatment in DIBH, however, the impact on the normal tissue dose was highly individual and therefore comparative treatment planning is encouraged. The lowest OAR doses were generally observed for IMPT in combination with DIBH. PMID- 30280627 TI - Life filming as a means of participatory approach together with older community dwelling persons regarding their local environment. AB - BACKGROUND: The potential to influence the design of one's local environment is especially important to older people since age-related problems, in combination with a less supportive environment, can prevent the performance of meaningful activities. It is unclear how best to tailor a participatory approach to support the task of collaborating with older persons about their local environment. Life filming was used in such a project. OBJECTIVE: To describe Life filming as a means of participatory approach in relation to older community-dwelling persons and the design of their local environment. MATERIAL AND METHOD: A descriptive single case study. Data were generated through field notes and memos, and analyzed utilizing thematic analysis. Participants have validated the findings. FINDINGS: Five themes describe central aspects of Life filming in the given context: Anchoring the concept of participation, Practical application of Life filming, The film as a product, Making a real difference, and An identity as a capable older person. CONCLUSION: Life filming supported participation, both as a process and an outcome. It had benefits on multiple levels: for the individual person, for older persons as a group, and for the municipality. Life filming could constitute a useful digital tool for practice when a participatory approach is desired. PMID- 30280628 TI - Real-world use of PCSK9 inhibitors: A single-center experience. AB - Objective Hyperlipidemia is an important risk factor for atherosclerotic cardiovascular disease. Many patients are intolerant to or have limited benefit from statins. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors have been approved for treating hyperlipidemia in these patients. We sought to investigate the impact of these medications in a real-world cardiology practice. Methods This was a retrospective study of 17 patients with either heterozygous familial hypercholesterolemia or established atherosclerotic cardiovascular disease with low-density lipoprotein cholesterol (LDL-C) levels above the treatment target despite maximally tolerated statins. Baseline lipid profile was compared with a repeat lipid profile obtained 4 to 6 weeks after initiating treatment with a PCSK9 inhibitor. Results The average duration of PCSK9 inhibitor treatment was 10.7 months. Lipid profile comparison showed that total cholesterol decreased from 243 +/- 72 to 148 +/- 39 (mg/dL) (39% reduction), triglycerides decreased from 185 +/- 86 to 149 +/- 62 (mg/dL) (19.5% reduction), high-density lipoprotein cholesterol increased from 56 +/- 20 to 62 +/- 26 (mg/dL) (10.7% increase), and LDL-C decreased from 154 +/- 30 to 57 +/- 32 (mg/dL) (63% reduction) from baseline. Conclusions PCSK9 inhibitors as add-on therapy to maximally tolerated statins resulted in an approximately 63% reduction in LDL-C. PMID- 30280629 TI - Creating opportunities for occupational development using the concerns report method. AB - BACKGROUND: Little research has focused on working with communities to promote and support children's occupational development. AIM/OBJECTIVE: We used the Concerns Report Method (CRM) to identify community supports for parents with young children that could enhance children's occupational development. MATERIAL AND METHOD: We conducted interviews/focus groups with parents (n = 29) and service providers (n = 11). We used content analysis to identify four themes: availability, barriers and facilitators, parent/child transitions, and making connections. The themes were used to create a concerns report survey for parents and service providers. A random sample of parents (n = 319) and convenience sample of service providers (n = 47) in one community area of a Canadian urban center completed the on-line survey. We held a community forum to review the results and identify solutions for action. RESULTS: Parents' highest priorities included childcare, supports in community schools, preschool programs, and supports in one location. Service providers highest priorities included: identification of developmental concerns; parenting education; programs for fathers, programs that offer child care, a doctor, and child care. CONCLUSIONS: Service providers need to engage parents and consider parents' perspectives when planning services to ensure community supports will meet parent identified needs. SIGNIFICANCE: Using community-based participatory research approaches, occupational therapists can contribute to children's occupational development. PMID- 30280630 TI - Caregivers of patients receiving long-term treatment with a tyrosine kinase inhibitor (TKI) for gastrointestinal stromal tumour (GIST): a cross-sectional assessment of their distress and burden. AB - BACKGROUND: TKIs are a long-term treatment for GIST, and may have an impact on caregivers. MATERIAL AND METHODS: For this cross-sectional study, patients and caregivers were both included when patients had been treated with TKIs for at least six months. Caregivers completed questionnaires including demographics, distress (Hospital Anxiety and Depression scale), burden (Self-Perceived Pressure from Informal Care) general health (RAND-36), comorbidity (Self-administered Comorbidity Questionnaire), social support (Social Support List - Discrepancies) and marital satisfaction (Maudsley Marital Questionnaire). Patients completed similar questionnaires, without 'burden'. We conducted analyses to explore differences between caregivers with low/moderate versus high levels of burden and low versus high levels of distress. RESULTS: Sixty-one out of seventy-one eligible couples (84%) were included in the analysis. The median age of the caregivers was 60 years; 66% were female and 78% were the patients' spouse. The median age of the patients was 66 years; 43% were female. Caregivers experienced high levels of burden and distress in 10% and 23%, respectively. Caregivers with high levels of burden perceived significantly lower mental health, less vitality, lower general health and high levels of distress. Significantly higher levels of burden were found in non-spouses, caregivers of patients with more treatment related side-effects, caregivers who spent more hours caring, and those caring for more than one person. For distress, caregivers with high levels of distress perceived significantly more burden, lower social functioning, more role physical and emotional problems, lower mental health, less vitality and lower general health. Furthermore, high levels of distress were found in caregivers of more dependent patients and those caring for more than one person. CONCLUSIONS: Caregivers of the patients with GIST treated with TKI are managing well. There is a small, vulnerable group of caregivers with high levels of burden and/or distress, show more health-related problems, both physical and mental, and require adequate support.

AB - PURPOSE: Online 1.5T MR imaging on the MR-linac gives better target visualization compared to CBCT and facilitates online adaptive treatment strategies including daily replanning. In this simulation study, the dosimetric impact of online replanning was investigated for SBRT of lymph node oligometastases as a method for correcting for inter-fraction anatomical changes. METHODS: Pre-treatment plans were created for 17 pelvic and para-aortic lymph nodes, with 3 and 8 mm PTV margins reflecting our clinical practice for lymph nodes with good and poor visibility on CBCT. The dose-volume parameters of the pre-treatment plans were evaluated on daily anatomy as visible on the repeated MRIs and compared to online replanning. RESULTS: With online MRI-based replanning significant dosimetric improvements are obtained for the rectum, bladder, bowel and sigmoid without compromising the target dose. The amount of unintended violations of the dose constraints for target and surrounding organs could be reduced by 75% for 8 mm and 66% for 3 mm PTV margins. CONCLUSION: The use of online replanning based on the actual anatomy as seen on repeated MRI compared to online position correction for lymph node oligometastases SBRT gives beneficial dosimetric outcomes and reduces the amount of unplanned violations of dose constraints.

AB - BACKGROUND: Age-associated neurocognitive disorders (NCDs) are associated with progressive loss of abilities for instrumental activities of daily living, including driving. This study assesses the impact of NCD diagnosis, while controlling for reported level of cognitive impairment, on family caregiver judgment of driving safety. METHOD: An intervention sample of 152 intergenerational caregivers who assist an older adult with medical tasks was used. Caregiver's pre-intervention response to a single item of confidence in the older adult driving was used to determine judgment of driving ability. Cognitive impairment was assessed using caregivers' report for Clinical Dementia Rating (CDR) Sum of Boxes score. RESULTS: Older adults with a diagnosis were rated as less capable of driving safely than those without a diagnosis, while controlling for reported level of cognitive impairment. CONCLUSION: Results of this study highlight the importance of NCD diagnosis on caregiver judgments. Results of this study have implications for health care and driving safety. PMID- 30280633 TI - Survival and prognostic factors of pulmonary oligometastases treated with stereotactic body radiotherapy. AB - BACKGROUND: Stereotactic body radiotherapy (SBRT) for pulmonary oligometastatic disease achieves excellent treatment outcomes in terms of local control and toxicity. Patients treated with SBRT are often elderly and have multiple co morbidities. This subset of patients may experience different survival as compared to young and fit patients subjected to radical metastasectomies. The purpose of this retrospective study was to evaluate OS and identify factors associated with OS for inoperable pulmonary oligometastases treated with SBRT. MATERIAL AND METHODS: Criteria used for selection of patients with oligometastases included: metastases limited to <=2 organs and in total <=5 metastases at the time of treatment. Peripheral tumors were treated with 51 Gy to 60 Gy in three fractions or a single fraction of 30 Gy. Central tumors received a dose of 45-60 Gy in 5-8 fractions. Survival probabilities were estimated by means of Kaplan-Meier method and the relation between potential prognostic factors and OS was studied by means of Cox regression analyses. RESULTS: In this study, 327 inoperable pulmonary oligometastases in 206 patients were treated with SBRT from the year 2005 to 2015. Primary sites of pulmonary oligometastases included colorectal carcinoma (n = 118), lung carcinoma (n = 36), melanoma (n = 11), sarcoma (n = 10), breast carcinoma (n = 7), and other tumors sites (n = 24). Median follow-up was 26 months. Median survival was 33 months. The 2-year and 5 year OS rates were 63% and 30%, respectively. On univariate analysis synchronous oligometastases (HR 0.59) and colorectal primary (HR 0.64) were associated with improved OS. On multivariable analysis synchronous oligometastases (HR 0.56), colorectal primary (HR 0.62) and tumor size <3 cm (HR 0.68) were independently associated with OS. CONCLUSIONS: SBRT to pulmonary oligometastases was associated with a 2-year OS of 63%. Tumor size <3 cm and colorectal primary tumors experienced improved OS compared to tumors >3 cm and non-colorectal primary tumors. PMID- 30280634 TI - The Impact of Adverse Childhood Events on the Sexual and Mental Health of Women Experiencing Intimate Partner Violence. AB - Women experiencing intimate partner violence (IPV) are at an increased risk of engaging in sexual risk behaviors and experiencing depressive and posttraumatic stress symptoms. Adverse childhood events (ACEs) can put women at increased risk of poor sexual and mental health. Women experiencing IPV report ACEs, but few studies have examined the heterogeneity in women's experiences of ACEs and its effects on sexual and mental health. Therefore, the current study used latent profile analysis to identify profiles of ACEs (i.e., witnessing maternal and paternal IPV victimization; childhood physical, sexual, and emotional abuse; and physical and emotional neglect) and their association with sexual risk behaviors and depressive and posttraumatic stress symptoms. Women experiencing IPV aged 18 to 58 years ( N = 212) were recruited from community establishments and completed face-to-face, computer-assisted interviews. Three profiles were identified: Low ACEs class ( n = 115), Moderate ACEs class ( n = 62), and High ACEs class ( n = 35). Path analyses revealed that profiles of ACEs directly predicted women's IPV victimization severity and depressive and posttraumatic stress symptoms. Secondary and tertiary mental health interventions may be more effective if the heterogeneity in women's ACEs is addressed by integrating intervention strategies specific to these ACE subgroups. PMID- 30280637 TI - Is a delay in the introduction of human papillomavirus-based cervical screening affordable? AB - Objective It often takes considerable time for sufficient evidence to accumulate to support implementation of new methods in routine screening. Where national screening programmes are already effective, switching to a more sensitive screening test may not be a priority. Although risk associated with overly rapid implementation exists, postponement is also associated with a (to date unquantified) missed opportunity to prevent deaths. This risk tends not to be addressed where effective screening methods are already in use. We here estimate the monetary value of a one-year delay in replacing cytology cervical screening with human papillomavirus testing. Methods Using a previously validated model, we calculated the number of incident and fatal cervical cancers that would be diagnosed by 2030 in England, under the assumption that human papillomavirus testing replaces cytology in 2020 rather than 2019, and the monetary value of the quality-adjusted life years lost in preventable cases. Results A one-year delay in the implementation of human papillomavirus screening would miss the opportunity to prevent 581 cases of cervical cancer, and lead to a loss of 1595 quality-adjusted life years (3.5% discount rate) with a monetary value of L32 million (at L20,000 per quality-adjusted life year). Conclusion This is a measurable loss and should be considered in prioritising decision-making in screening. PMID- 30280638 TI - Region-Specific Phenotypes of Microglia: The Role of Local Regulatory Cues. AB - Microglia are ubiquitous, macrophage like cells within the central nervous system (CNS) that play critical roles in supporting neuronal health and viability. They can also influence neuronal membrane properties and synaptic connectivity, positioning microglia as key cellular players in both physiological and pathological contexts. Microglia have generally been assumed to be equivalent throughout the CNS, but accumulating evidence indicates that their properties vary substantially across distinct CNS regions. In comparison to our understanding of neuronal diversity and its functional importance, our knowledge about causes and consequences of microglial regional heterogeneity is extremely limited. To fully understand how microglia influence the function of specific neuronal populations and shape heightened susceptibility of some neurons to damage and disease, greater focus on microglial heterogeneity is needed. PMID- 30280636 TI - Mouse mast cells and mast cell proteases do not play a significant role in acute tissue injury pain induced by formalin. AB - Subcutaneous formalin injections are used as a model for tissue injury-induced pain where formalin induces pain and inflammation indirectly by crosslinking proteins and directly through activation of the transient receptor potential A1 receptor on primary afferents. Activation of primary afferents leads to both central and peripheral release of neurotransmitters. Mast cells are found in close proximity to peripheral sensory nerve endings and express receptors for neurotransmitters released by the primary afferents, contributing to the neuro/immune interface. Mast cell proteases are found in large quantities within mast cell granules and are released continuously in small amounts and upon mast cell activation. They have a wide repertoire of proposed substrates, including Substance P and calcitonin gene-related peptide, but knowledge of their in vivo function is limited. We evaluated the role of mouse mast cell proteases (mMCPs) in tissue injury pain responses induced by formalin, using transgenic mice lacking either mMCP4, mMCP6, or carboxypeptidase A3 (CPA3), or mast cells in their entirety. Further, we investigated the role of mast cells in heat hypersensitivity following a nerve growth factor injection. No statistical difference was observed between the respective mast cell protease knockout lines and wild-type controls in the formalin test. Mast cell deficiency did not have an effect on formalin-induced nociceptive responses nor nerve growth factor-induced heat hypersensitivity. Our data thus show that mMCP4, mMCP6, and CPA3 as well as mast cells as a whole, do not play a significant role in the pain responses associated with acute tissue injury and inflammation in the formalin test. Our data also indicate that mast cells are not essential to heat hypersensitivity induced by nerve growth factor. PMID- 30280639 TI - Digital Intimate Partner Violence Among Peruvian Youths: Validation of an Instrument and a Theoretical Proposal. AB - The present study presents psychometric information on a new instrument, the Digital Intimate Partner Violence Questionnaire (DIPVQ), and explores the similitudes and differences between in-person and digital-based abuses (those that involve the use of information and communication technologies [ICTs]). In all, 449 Peruvian students took part in the study ( X = 21.2 years; SD = 4.3 years; 73% women). DIPVQ structure was determined by carrying out an exploratory factor analysis (EFA) with polychoric correlation matrices and oblique rotation. In-person violence was assessed using the Dating Violence Questionnaire (DVQ) and self-labeling questions (e.g., feeling trapped, afraid, and abused). Relationship satisfaction was assessed using the Perceived Relationship Quality Components Short Form (PRQC-SF). EFA showed a two-scale structure for the DIPVQ: control centered cyberabuse ( N = 5; control, monitoring, and identity theft; EAP alpha = .96) and damage-centered cyberabuse ( N = 7; unwanted sexual contents, blackmailing, and causing debts throughout ICT; Expected-A-Posteriori alpha = .97). DIPVQ had direct relationship to DVQ and self-labeling ( p < .001; d = 0.38 1.18), and inverse to PRQC-SF ( p = .11; d = .22-.33). Behaviors such as impersonation and monitoring were reported by more than 20% of participants. Online and offline victimization coexist in 42% of cases, while 3.6% of aggressions happened exclusively via ICT. DIPVQ is a valid and reliable measure of digital victimization. The control-centered scale had a higher frequency, although the damage-centered scale had stronger relationship to feeling afraid and abused. While previous literature has classified online aggressions regarding their aesthetic appearance, it seems that their functional value (control vs. hurting) could provide a better framework for understanding these aggressions. PMID- 30280640 TI - Transcatheter Mitral-Valve Repair in Patients with Heart Failure. AB - BACKGROUND: Among patients with heart failure who have mitral regurgitation due to left ventricular dysfunction, the prognosis is poor. Transcatheter mitral valve repair may improve their clinical outcomes. METHODS: At 78 sites in the United States and Canada, we enrolled patients with heart failure and moderate-to severe or severe secondary mitral regurgitation who remained symptomatic despite the use of maximal doses of guideline-directed medical therapy. Patients were randomly assigned to transcatheter mitral-valve repair plus medical therapy (device group) or medical therapy alone (control group). The primary effectiveness end point was all hospitalizations for heart failure within 24 months of follow-up. The primary safety end point was freedom from device-related complications at 12 months; the rate for this end point was compared with a prespecified objective performance goal of 88.0%. RESULTS: Of the 614 patients who were enrolled in the trial, 302 were assigned to the device group and 312 to the control group. The annualized rate of all hospitalizations for heart failure within 24 months was 35.8% per patient-year in the device group as compared with 67.9% per patient-year in the control group (hazard ratio, 0.53; 95% confidence interval [CI], 0.40 to 0.70; P<0.001). The rate of freedom from device-related complications at 12 months was 96.6% (lower 95% confidence limit, 94.8%; P<0.001 for comparison with the performance goal). Death from any cause within 24 months occurred in 29.1% of the patients in the device group as compared with 46.1% in the control group (hazard ratio, 0.62; 95% CI, 0.46 to 0.82; P<0.001). CONCLUSIONS: Among patients with heart failure and moderate-to-severe or severe secondary mitral regurgitation who remained symptomatic despite the use of maximal doses of guideline-directed medical therapy, transcatheter mitral-valve repair resulted in a lower rate of hospitalization for heart failure and lower all-cause mortality within 24 months of follow-up than medical therapy alone. The rate of freedom from device-related complications exceeded a prespecified safety threshold. (Funded by Abbott; COAPT ClinicalTrials.gov number, NCT01626079 .). PMID- 30280635 TI - Pembrolizumab plus Chemotherapy for Squamous Non-Small-Cell Lung Cancer. AB - BACKGROUND: Standard first-line therapy for metastatic, squamous non-small-cell lung cancer (NSCLC) is platinum-based chemotherapy or pembrolizumab (for patients with programmed death ligand 1 [PD-L1] expression on >=50% of tumor cells). More recently, pembrolizumab plus chemotherapy was shown to significantly prolong overall survival among patients with nonsquamous NSCLC. METHODS: In this double blind, phase 3 trial, we randomly assigned, in a 1:1 ratio, 559 patients with untreated metastatic, squamous NSCLC to receive 200 mg of pembrolizumab or saline placebo for up to 35 cycles; all the patients also received carboplatin and either paclitaxel or nanoparticle albumin-bound [nab]-paclitaxel for the first 4 cycles. Primary end points were overall survival and progression-free survival. RESULTS: After a median follow-up of 7.8 months, the median overall survival was 15.9 months (95% confidence interval [CI], 13.2 to not reached) in the pembrolizumab-combination group and 11.3 months (95% CI, 9.5 to 14.8) in the placebo-combination group (hazard ratio for death, 0.64; 95% CI, 0.49 to 0.85; P<0.001). The overall survival benefit was consistent regardless of the level of PD-L1 expression. The median progression-free survival was 6.4 months (95% CI, 6.2 to 8.3) in the pembrolizumab-combination group and 4.8 months (95% CI, 4.3 to 5.7) in the placebo-combination group (hazard ratio for disease progression or death, 0.56; 95% CI, 0.45 to 0.70; P<0.001). Adverse events of grade 3 or higher occurred in 69.8% of the patients in the pembrolizumab-combination group and in 68.2% of the patients in the placebo-combination group. Discontinuation of treatment because of adverse events was more frequent in the pembrolizumab combination group than in the placebo-combination group (13.3% vs. 6.4%). CONCLUSIONS: In patients with previously untreated metastatic, squamous NSCLC, the addition of pembrolizumab to chemotherapy with carboplatin plus paclitaxel or nab-paclitaxel resulted in significantly longer overall survival and progression free survival than chemotherapy alone.

PMID- 30280641 TI - First-Line Atezolizumab plus Chemotherapy in Extensive-Stage Small-Cell Lung Cancer. AB - BACKGROUND: Enhancing tumor-specific T-cell immunity by inhibiting programmed death ligand 1 (PD-L1)-programmed death 1 (PD-1) signaling has shown promise in the treatment of extensive-stage small-cell lung cancer. Combining checkpoint inhibition with cytotoxic chemotherapy may have a synergistic effect and improve efficacy. METHODS: We conducted this double-blind, placebo-controlled, phase 3 trial to evaluate atezolizumab plus carboplatin and etoposide in patients with extensive-stage small-cell lung cancer who had not previously received treatment. Patients were randomly assigned in a 1:1 ratio to receive carboplatin and etoposide with either atezolizumab or placebo for four 21-day cycles (induction phase), followed by a maintenance phase during which they received either atezolizumab or placebo (according to the previous random assignment) until they had unacceptable toxic effects, disease progression according to Response Evaluation Criteria in Solid Tumors, version 1.1, or no additional clinical benefit. The two primary end points were investigator-assessed progression-free survival and overall survival in the intention-to-treat population. RESULTS: A total of 201 patients were randomly assigned to the atezolizumab group, and 202 patients to the placebo group. At a median follow-up of 13.9 months, the median overall survival was 12.3 months in the atezolizumab group and 10.3 months in the placebo group (hazard ratio for death, 0.70; 95% confidence interval [CI], 0.54 to 0.91; P=0.007). The median progression-free survival was 5.2 months and 4.3 months, respectively (hazard ratio for disease progression or death, 0.77; 95% CI, 0.62 to 0.96; P=0.02). The safety profile of atezolizumab plus carboplatin and etoposide was consistent with the previously reported safety profile of the individual agents, with no new findings observed. CONCLUSIONS: The addition of atezolizumab to chemotherapy in the first-line treatment of extensive-stage small cell lung cancer resulted in significantly longer overall survival and progression-free survival than chemotherapy alone.

PMID- 30280643 TI - A subject-specific integrative biomechanical framework of the pelvis for gait analysis. AB - Analysis of the human locomotor system using rigid-body musculoskeletal models has increased in the biomechanical community with the objective of studying muscle activations of different movements. Simultaneously, the finite element method has emerged as a complementary approach for analyzing the mechanical behavior of tissues. This study presents an integrative biomechanical framework for gait analysis by linking a musculoskeletal model and a subject-specific finite element model of the pelvis. To investigate its performance, a convergence study was performed and its sensitivity to the use of non-subject-specific material properties was studied. The total hip joint force estimated by the rigid musculoskeletal model and by the finite element model showed good agreement, suggesting that the integrative approach estimates adequately (in shape and magnitude) the hip total contact force. Previous studies found movements of up to 1.4 mm in the anterior-posterior direction, for single leg stance. These results are comparable with the displacement values found in this study: 0-0.5 mm in the sagittal axis. Maximum von Mises stress values of approximately 17 MPa were found in the pelvic bone. Comparing this results with a previous study of our group, the new findings show that the introduction of muscular boundary conditions and the flexion-extension movement of the hip reduce the regions of high stress and distributes more uniformly the stress across the pelvic bone. Thus, it is thought that muscle force has a relevant impact in reducing stresses in pelvic bone during walking of the finite element model proposed in this study. Future work will focus on including other deformable structures, such as the femur and the tibia, and subject-specific material properties. PMID- 30280644 TI - Fumonisin occurrence in wheat-based products from Argentina. AB - In Argentina, wheat is the most consumed cereal by the human population. Since fumonisins occurence in wheat grains and wheat-based products have been reported worldwide, a survey was conducted in order to determine fumonisin contamination in 91 wheat-based products (white wheat flour samples, wheat flour used at bakery products and whole-wheat flour samples) collected from different retail stores of Rio Cuarto city in Argentina using HPLC-MS/MS. Sixty-seven samples (74%) showed contamination by fumonisins. From these samples, 16 showed fumonisin levels between LOD and LOQ (between 0.01 to 0.05 ng/g), while fumonisins (FB1 + FB2) in quantifiable samples ranged from 0.05 ng/g to 18.9 ng/g. Although FB1 was more prevalent, FB2 was foun3d in higher levels than FB1. Overall, fumonisin prevalence was high, but concentrations were far below EU or USA limits set for maize and maize-based products. PMID- 30280645 TI - Comparison of conventional methods of simultaneous intrusion and retraction of maxillary anterior: a finite element analysis. AB - OBJECTIVE: To study the biomechanical effects of the three-piece intrusion arch and Kalra simultaneous intrusion and retraction arch (K-SIR) on simultaneous intrusion and retraction of maxillary anterior teeth. DESIGN: Three-dimensional analysis of stresses and displacement of the anterior and posterior teeth with the three-piece intrusion arch and K-SIR arch was done using the finite element method (FEM). SETTING: Department of Orthodontics, Surendera Dental College and Research Institute, India. MATERIAL AND METHODS: For this investigation, the geometric model of the maxilla was constructed using a computed tomography scan. 0.022 * 0.028-inch MBT brackets and molar tubes were modelled, with the specified tip and torque values for all maxillary teeth. The wire components for the three piece intrusion arch and K-SIR arch were modelled initially as a line diagram and then converted to three dimensional models. The material characteristics which include the Young's modulus and Poisson's ratio were assigned. After defining the boundary conditions, force systems were applied as per design. The analysis was carried out using ANSYS Version 12.1 software. The von Mises stress, principal stress on PDL and alveolar bone, change in the inclination of incisors and initial displacement of the teeth in bucco-palatal, mesio- distal and vertical direction were analysed. RESULTS: Stresses in cortical bone were greater than cancellous. Both modalities showed intrusion of the anterior teeth, although this was slightly more in the three- piece intrusion arch. On studying the principal stresses in the PDL, the three-piece intrusion arch displayed uniform stress distribution compared to K-SIR arch. CONCLUSION: The FEM cannot reflect actual biological responses within the human body to orthodontic forces but based on these findings, the three-piece intrusion arch showed better stress distribution and controlled tooth movement than the K-SIR arch. PMID- 30280647 TI - Comparison of cross-matching method for detection of DEA 7 blood incompatibility. AB - We compared 3 major cross-match (XM) tests to identify dog erythrocyte antigen (DEA) 7 blood incompatibilities in dogs as a result of anti-DEA 7 antibodies: gel (GEL), standard tube (TUBE) agglutination, and immunochromatography strips (STRIP). Blood samples from 42 dogs were typed for DEA 7; 2 tested DEA 7-positive (DEA 7+). The 40 DEA 7-negative (DEA 7-) plasma samples were cross-matched against the 2 DEA 7+ and 3 DEA 7- red blood cell (RBC) samples by GEL to identify samples with anti-DEA 7 antibodies. Twenty DEA 7- plasma samples without and with anti-DEA 7 antibodies were cross-matched with samples of the 2 DEA 7+ RBCs in a double-blind fashion using the TUBE and STRIP XM methods. GEL results were used as the reference method for comparison. To determine relationships between results, 2 * 2 tables were used. Cohen kappa coefficient (kappa) was calculated between results of GEL and the other 2 methods. With GEL, 21 of 40 XM tests were positive and 19 of 40 negative for anti-DEA 7 antibodies. The same results were obtained by TUBE, whereas only 1 of 40 XM tests was positive by STRIP. There was a statistically significant relationship between results of GEL and TUBE ( p < 0.000) with perfect agreement (kappa = 1.000), but not between GEL and STRIP results ( p = 1.000) in which agreement was equivalent to chance (kappa = 0.0453). The GEL and TUBE XM tests, but not STRIP, are useful methods for identification of DEA 7 incompatibilities caused by anti-DEA 7 antibodies. PMID- 30280648 TI - Drug-Coated Balloon Treatment of Femoropopliteal Lesions Typically Excluded From Clinical Trials: 12-Month Findings From the IN.PACT Global Study. AB - PURPOSE: To report a post hoc analysis comparing outcomes between subjects who would have been included in the IN.PACT SFA randomized controlled trial vs those who would have been excluded. METHODS: The 1406 subjects enrolled in the IN.PACT Global Study ( ClinicalTrials.gov identifier NCT01609296) were retrospectively assigned to a standard-use group (n=281) based on the inclusion and exclusion criteria from the randomized IN.PACT SFA trial; the remaining 1125 patients were assigned to the broader-use group. Freedom from clinically-driven target lesion revascularization (CD-TLR) was evaluated at 12 months. The composite primary safety endpoint was freedom from 30-day device- and procedure-related death plus freedom from 12-month target limb major amputation and clinically-driven target vessel revascularization (CD-TVR). Functional outcomes were evaluated with dedicated questionnaires. RESULTS: Compared with the standard-use cohort, the broader-use lesions were longer, more calcified, and had more popliteal involvement, bilateral disease, and in-stent restenosis (p<0.001 for all). Freedom from 12-month CD-TLR by Kaplan-Meier analysis was 96.6% for the standard use group and 91.6% for the broader-use group (p=0.005). The safety endpoint was 96.2% in the standard-use group and 91.0% in the broader-use group (p=0.003). The 12-month CD-TLR (3.4% standard-use vs 8.5% broader-use, p=0.004) and CD-TVR (4.2% standard-use vs 9.1% broader-use, p=0.008) were increased in the broader-use group. Twelve-month all-cause mortality was not increased (3.8% standard-use vs 3.4% broader-use, p=0.852). CONCLUSION: Post hoc analysis of the IN.PACT Global Study of real-world patients demonstrated consistent outcomes with significant clinical improvement to 12 months in subjects with complex lesions typically excluded from a randomized controlled trial. PMID- 30280646 TI - Prediction of Susceptibility to First-Line Tuberculosis Drugs by DNA Sequencing. AB - BACKGROUND: The World Health Organization recommends drug-susceptibility testing of Mycobacterium tuberculosis complex for all patients with tuberculosis to guide treatment decisions and improve outcomes. Whether DNA sequencing can be used to accurately predict profiles of susceptibility to first-line antituberculosis drugs has not been clear. METHODS: We obtained whole-genome sequences and associated phenotypes of resistance or susceptibility to the first-line antituberculosis drugs isoniazid, rifampin, ethambutol, and pyrazinamide for isolates from 16 countries across six continents. For each isolate, mutations associated with drug resistance and drug susceptibility were identified across nine genes, and individual phenotypes were predicted unless mutations of unknown association were also present. To identify how whole-genome sequencing might direct first-line drug therapy, complete susceptibility profiles were predicted. These profiles were predicted to be susceptible to all four drugs (i.e., pansusceptible) if they were predicted to be susceptible to isoniazid and to the other drugs or if they contained mutations of unknown association in genes that affect susceptibility to the other drugs. We simulated the way in which the negative predictive value changed with the prevalence of drug resistance. RESULTS: A total of 10,209 isolates were analyzed. The largest proportion of phenotypes was predicted for rifampin (9660 [95.4%] of 10,130) and the smallest was predicted for ethambutol (8794 [89.8%] of 9794). Resistance to isoniazid, rifampin, ethambutol, and pyrazinamide was correctly predicted with 97.1%, 97.5%, 94.6%, and 91.3% sensitivity, respectively, and susceptibility to these drugs was correctly predicted with 99.0%, 98.8%, 93.6%, and 96.8% specificity. Of the 7516 isolates with complete phenotypic drug-susceptibility profiles, 5865 (78.0%) had complete genotypic predictions, among which 5250 profiles (89.5%) were correctly predicted. Among the 4037 phenotypic profiles that were predicted to be pansusceptible, 3952 (97.9%) were correctly predicted. CONCLUSIONS: Genotypic predictions of the susceptibility of M. tuberculosis to first-line drugs were found to be correlated with phenotypic susceptibility to these drugs.

AB - PURPOSE:: To evaluate the safety and performance of the Treovance stent-graft. METHODS:: The global, multicenter RATIONALE registry ( ClinicalTrials.gov; identifier NCT03449875) prospectively enrolled 202 patients (mean age 73.0+/-7.8 years; 187 men) with abdominal aortic aneurysms (AAA) suitable for endovascular aneurysm repair (EVAR) using the Treovance. The composite primary safety endpoint was site-reported all-cause mortality and major morbidity. The primary efficacy outcome was clinical success. Further outcomes evaluated included technical success; stent-graft migration, patency, and integrity; endoleak; and aneurysm size changes. RESULTS:: Technical success was 96% (194/202); 8 patients had unresolved type I endoleaks at the end of the procedure. There was no 30-day mortality and 1% major morbidity (1 myocardial infarction and 1 bowel ischemia). Clinical success at 1 year was confirmed in 194 (96%) patients; 6 of 8 patients had new/persistent endoleaks and 2 had aneurysm expansion without identified endoleak. A total of 8 (4%) reinterventions were required during the mean 13.7+/ 3.1 months of follow-up (median 12.8). At 1 year, the Kaplan-Meier estimate for freedom from reintervention was 95.6% (95% CI 91.4% to 97.8%). Other estimates were 95.5% (95% CI 91.7% to 97.6%) for freedom from endoleak type I/III and 97.4% (95% CI 94.2% to 98.9%) for freedom from aneurysm expansion. Thirteen (6.4%) patients died; no death was aneurysm related. CONCLUSION:: The RATIONALE registry showed favorable safety and clinical performance of the Treovance stent-graft for the treatment of infrarenal AAAs in a real-world setting. PMID- 30280650 TI - Rapid differentiation of Staphylococcus aureus subspecies based on MALDI-TOF MS profiles. AB - Staphylococcus aureus encompasses 2 subspecies ( aureus and anaerobius) with significant differences in their epidemiology and pathogenicity. We evaluated the suitability of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) for the rapid identification of both subspecies using a panel of 52 S. aureus isolates (30 subsp. anaerobius and 22 subsp. aureus) recovered from different origins, countries, and years. The on-board library identification system correctly identified 42 of 52 (81%) S. aureus isolates at the species level with score values >2.0. Limited performance was observed for differentiation of S. aureus subspecies (particularly subsp. anaerobius). Visual inspection of MALDI-TOF MS profiles identified 5 subspecies-specific mass peaks ( m/ z 3430 and 6861 in S. aureus subsp. anaerobius, and m/ z 4046, 6890, and 8093 in S. aureus subsp. aureus) with 100% sensitivity and specificity values, which is potentially useful for differentiating these subspecies. The suitability of 3 models, Genetic Analysis (GA), Quick Classifier (QC), and Supervised Neural Network, for automatic identification of both subspecies was evaluated using the Recognition Capability (RC) and Cross Validation (CV) values provided by the on board ClinProTools software. The GA and QC models reached RC and CV values of 100%. Both models were externally validated using a panel of 26 S. aureus isolates of both subspecies, with both models correctly classifying all isolates of both subspecies. MALDI-TOF MS coupled with ClinProTools software represents a rapid and simple approach for S. aureus subspecies discrimination.

AB - The blood-brain barrier (BBB) prevents neurotoxic plasma components, blood cells, and pathogens from entering the brain. At the same time, the BBB regulates transport of molecules into and out of the central nervous system (CNS), which maintains tightly controlled chemical composition of the neuronal milieu that is required for proper neuronal functioning. In this review, we first examine molecular and cellular mechanisms underlying the establishment of the BBB. Then, we focus on BBB transport physiology, endothelial and pericyte transporters, and perivascular and paravascular transport. Next, we discuss rare human monogenic neurological disorders with the primary genetic defect in BBB-associated cells demonstrating the link between BBB breakdown and neurodegeneration. Then, we review the effects of genes underlying inheritance and/or increased susceptibility for Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease, and amyotrophic lateral sclerosis (ALS) on BBB in relation to other pathologies and neurological deficits. We next examine how BBB dysfunction relates to neurological deficits and other pathologies in the majority of sporadic AD, PD, and ALS cases, multiple sclerosis, other neurodegenerative disorders, and acute CNS disorders such as stroke, traumatic brain injury, spinal cord injury, and epilepsy. Lastly, we discuss BBB-based therapeutic opportunities. We conclude with lessons learned and future directions, with emphasis on technological advances to investigate the BBB functions in the living human brain, and at the molecular and cellular level, and address key unanswered questions. PMID- 30280651 TI - Phase 2b Controlled Trial of M72/AS01E Vaccine to Prevent Tuberculosis. AB - BACKGROUND: A vaccine to interrupt the transmission of tuberculosis is needed. METHODS: We conducted a randomized, double-blind, placebo-controlled, phase 2b trial of the M72/AS01E tuberculosis vaccine in Kenya, South Africa, and Zambia. Human immunodeficiency virus (HIV)-negative adults 18 to 50 years of age with latent M. tuberculosis infection (by interferon-gamma release assay) were randomly assigned (in a 1:1 ratio) to receive two doses of either M72/AS01E or placebo intramuscularly 1 month apart. Most participants had previously received the bacille Calmette-Guerin vaccine. We assessed the safety of M72/AS01E and its efficacy against progression to bacteriologically confirmed active pulmonary tuberculosis disease. Clinical suspicion of tuberculosis was confirmed with sputum by means of a polymerase-chain-reaction test, mycobacterial culture, or both. RESULTS: We report the primary analysis (conducted after a mean of 2.3 years of follow-up) of the ongoing trial. A total of 1786 participants received M72/AS01E and 1787 received placebo, and 1623 and 1660 participants in the respective groups were included in the according-to-protocol efficacy cohort. A total of 10 participants in the M72/AS01E group met the primary case definition (bacteriologically confirmed active pulmonary tuberculosis, with confirmation before treatment), as compared with 22 participants in the placebo group (incidence, 0.3 cases vs. 0.6 cases per 100 person-years). The vaccine efficacy was 54.0% (90% confidence interval [CI], 13.9 to 75.4; 95% CI, 2.9 to 78.2; P=0.04). Results for the total vaccinated efficacy cohort were similar (vaccine efficacy, 57.0%; 90% CI, 19.9 to 76.9; 95% CI, 9.7 to 79.5; P=0.03). There were more unsolicited reports of adverse events in the M72/AS01E group (67.4%) than in the placebo group (45.4%) within 30 days after injection, with the difference attributed mainly to injection-site reactions and influenza-like symptoms. Serious adverse events, potential immune-mediated diseases, and deaths occurred with similar frequencies in the two groups. CONCLUSIONS: M72/AS01E provided 54.0% protection for M. tuberculosis-infected adults against active pulmonary tuberculosis disease, without evident safety concerns.

PMID- 30280656 TI - [EXPRESS] CD11b activated Src signal attenuates neuroinflammatory pain by orchestrating inflammatory and anti-inflammatory cytokines in microglia. AB - Neuroinflammation plays an important role in the induction and maintenance of chronic pain. Orchestra of pattern-recognition receptors (PRRs) induced pro inflammatory and anti-inflammatory cytokines are critical for inflammation homeostasis. CD11b on macrophages could inhibit toll like receptor (TLR) activation induced inflammatory responses. However, the function of CD11b on microglia remains unknown. In the current study, we demonstrated that CD11b deficient microglia cells produced more inflammatory cytokines such as IL-6 and TNF-alpha, while less anti-inflammatory cytokines. Signal transduction assay confirmed that NF-kappaB activation was increased in CD11b deficient microglia cells, which was resulted from decreased activation of Src. Inhibition of Src by PP1 increased inflammation in wildtype microglia cells significantly, but not in CD11b deficient microglia cells. In vivo, CD11b deficient mice were more susceptible to CCI induced allodynia and hyperalgesia with significantly more inflammatory cytokines expression. All these results indicated that the regulatory function of CD11b-Src signal pathway on both inflammatory and anti inflammatory cytokines in microglia cells, which is a potential target in neuropathic pain treatment. PMID- 30280655 TI - An Outbreak of Synthetic Cannabinoid-Associated Coagulopathy in Illinois. AB - BACKGROUND: In March and April 2018, more than 150 patients presented to hospitals in Illinois with coagulopathy and bleeding diathesis. Area physicians and public health organizations identified an association between coagulopathy and synthetic cannabinoid use. Preliminary tests of patient serum samples and drug samples revealed that brodifacoum, an anticoagulant, was the likely adulterant. METHODS: We reviewed physician-reported data from patients admitted to Saint Francis Medical Center in Peoria, Illinois, between March 28 and April 21, 2018, and included in a case series adult patients who met the criteria used to diagnose synthetic cannabinoid-associated coagulopathy. A confirmatory anticoagulant poisoning panel was ordered at the discretion of the treating physician. RESULTS: A total of 34 patients were identified as having synthetic cannabinoid-associated coagulopathy during 45 hospitalizations. Confirmatory anticoagulant testing was performed in 15 of the 34 patients, and superwarfarin poisoning was confirmed in the 15 patients tested. Anticoagulant tests were positive for brodifacoum in 15 patients (100%), difenacoum in 5 (33%), bromadiolone in 2 (13%), and warfarin in 1 (7%). Common symptoms at presentation included gross hematuria in 19 patients (56%) and abdominal pain in 16 (47%). Computed tomography was performed to evaluate abdominal pain and revealed renal abnormalities in 12 patients. Vitamin K1 (phytonadione) was administered orally in all 34 patients and was also administered intravenously in 23 (68%). Red-cell transfusion was performed in 5 patients (15%), and fresh-frozen plasma infusion in 19 (56%). Four-factor prothrombin complex concentrate was used in 1 patient. One patient died from complications of spontaneous intracranial hemorrhage. CONCLUSIONS: Our data indicate that superwarfarin adulterants of synthetic cannabinoids can lead to clinically significant coagulopathy. In our series, in most of the cases in which the patient presented with bleeding diathesis, symptoms were controlled with the use of vitamin K1 replacement therapy. The specific synthetic cannabinoid compounds are not known. PMID- 30280657 TI - Brigatinib versus Crizotinib in ALK-Positive Non-Small-Cell Lung Cancer. AB - BACKGROUND: Brigatinib, a next-generation anaplastic lymphoma kinase (ALK) inhibitor, has robust efficacy in patients with ALK-positive non-small-cell lung cancer (NSCLC) that is refractory to crizotinib. The efficacy of brigatinib, as compared with crizotinib, in patients with advanced ALK-positive NSCLC who have not previously received an ALK inhibitor is unclear. METHODS: In an open-label, phase 3 trial, we randomly assigned, in a 1:1 ratio, patients with advanced ALK positive NSCLC who had not previously received ALK inhibitors to receive brigatinib at a dose of 180 mg once daily (with a 7-day lead-in period at 90 mg) or crizotinib at a dose of 250 mg twice daily. The primary end point was progression-free survival as assessed by blinded independent central review. Secondary end points included the objective response rate and intracranial response. The first interim analysis was planned when approximately 50% of 198 expected events of disease progression or death had occurred. RESULTS: A total of 275 patients underwent randomization; 137 were assigned to brigatinib and 138 to crizotinib. At the first interim analysis (99 events), the median follow-up was 11.0 months in the brigatinib group and 9.3 months in the crizotinib group. The rate of progression-free survival was higher with brigatinib than with crizotinib (estimated 12-month progression-free survival, 67% [95% confidence interval {CI}, 56 to 75] vs. 43% [95% CI, 32 to 53]; hazard ratio for disease progression or death, 0.49 [95% CI, 0.33 to 0.74]; P<0.001 by the log-rank test). The confirmed objective response rate was 71% (95% CI, 62 to 78) with brigatinib and 60% (95% CI, 51 to 68) with crizotinib; the confirmed rate of intracranial response among patients with measurable lesions was 78% (95% CI, 52 to 94) and 29% (95% CI, 11 to 52), respectively. No new safety concerns were noted. CONCLUSIONS: Among patients with ALK-positive NSCLC who had not previously received an ALK inhibitor, progression-free survival was significantly longer among patients who received brigatinib than among those who received crizotinib.

PMID- 30280654 TI - Wearable Cardioverter-Defibrillator after Myocardial Infarction. AB - BACKGROUND: Despite the high rate of sudden death after myocardial infarction among patients with a low ejection fraction, implantable cardioverter defibrillators are contraindicated until 40 to 90 days after myocardial infarction. Whether a wearable cardioverter-defibrillator would reduce the incidence of sudden death during this high-risk period is unclear. METHODS: We randomly assigned (in a 2:1 ratio) patients with acute myocardial infarction and an ejection fraction of 35% or less to receive a wearable cardioverter defibrillator plus guideline-directed therapy (the device group) or to receive only guideline-directed therapy (the control group). The primary outcome was the composite of sudden death or death from ventricular tachyarrhythmia at 90 days (arrhythmic death). Secondary outcomes included death from any cause and nonarrhythmic death. RESULTS: Of 2302 participants, 1524 were randomly assigned to the device group and 778 to the control group. Participants in the device group wore the device for a median of 18.0 hours per day (interquartile range, 3.8 to 22.7). Arrhythmic death occurred in 1.6% of the participants in the device group and in 2.4% of those in the control group (relative risk, 0.67; 95% confidence interval [CI], 0.37 to 1.21; P=0.18). Death from any cause occurred in 3.1% of the participants in the device group and in 4.9% of those in the control group (relative risk, 0.64; 95% CI, 0.43 to 0.98; uncorrected P=0.04), and nonarrhythmic death in 1.4% and 2.2%, respectively (relative risk, 0.63; 95% CI, 0.33 to 1.19; uncorrected P=0.15). Of the 48 participants in the device group who died, 12 were wearing the device at the time of death. A total of 20 participants in the device group (1.3%) received an appropriate shock, and 9 (0.6%) received an inappropriate shock. CONCLUSIONS: Among patients with a recent myocardial infarction and an ejection fraction of 35% or less, the wearable cardioverter defibrillator did not lead to a significantly lower rate of the primary outcome of arrhythmic death than control.

PMID- 30280660 TI - Activation of the glutathione peroxidase by metformin in the bile-duct ligation induced liver injury: in vivo combined with molecular docking studies. AB - Inhibition of hepatic fibrosis is an attainable objective in managing the chronic liver disease. The present study aimed to investigate possible defensive effects of metformin on activities of antioxidant enzymes, hydroxyproline content, and biochemical factors in bile duct ligation (BDL)-induced cholestatic rats. The interactive behavior of metformin with glutathione peroxidase (GPx) enzyme was also explained by molecular docking and conformation characterization. The present study was conducted on 28-adult male Wistar rats classified into four 7 animal groups: sham-control, mere BDL, and BDL+ metformin received daily metformin as gavage in two doses 250 and 500 mg/kg bw for 10 days. Biochemical analysis, hydroxyproline content, and antioxidant enzymes activity were also determined. The hydroxyproline content significantly increased, but the GPx enzyme activity significantly decreased in the hepatic tissue following BDL indicating that an oxidative stress-related model in rats was successfully constituted. Administration of metformin at two doses attenuated hydroxyproline content in the cholestatic liver and ameliorated the depletion of GPx enzyme activities compared to a non-treated BDL group (P-value <= 0.05). Molecular docking study provides the evidence for metformin ability to regulate enzymatic activity of GPx. The research data indicated that due to novel hepatoprotective effects of metformin in an animal model with BDL-induced liver injury, it was a potential beneficial therapeutic agent for treating the cholestatic liver disease. The main mechanism might contribute to antioxidant actions particularly via GPx enzyme. PMID- 30280658 TI - Overall Survival with Durvalumab after Chemoradiotherapy in Stage III NSCLC. AB - BACKGROUND: An earlier analysis in this phase 3 trial showed that durvalumab significantly prolonged progression-free survival, as compared with placebo, among patients with stage III, unresectable non-small-cell lung cancer (NSCLC) who did not have disease progression after concurrent chemoradiotherapy. Here we report the results for the second primary end point of overall survival. METHODS: We randomly assigned patients, in a 2:1 ratio, to receive durvalumab intravenously, at a dose of 10 mg per kilogram of body weight, or matching placebo every 2 weeks for up to 12 months. Randomization occurred 1 to 42 days after the patients had received chemoradiotherapy and was stratified according to age, sex, and smoking history. The primary end points were progression-free survival (as assessed by blinded independent central review) and overall survival. Secondary end points included the time to death or distant metastasis, the time to second progression, and safety. RESULTS: Of the 713 patients who underwent randomization, 709 received the assigned intervention (473 patients received durvalumab and 236 received placebo). As of March 22, 2018, the median follow-up was 25.2 months. The 24-month overall survival rate was 66.3% (95% confidence interval [CI], 61.7 to 70.4) in the durvalumab group, as compared with 55.6% (95% CI, 48.9 to 61.8) in the placebo group (two-sided P=0.005). Durvalumab significantly prolonged overall survival, as compared with placebo (stratified hazard ratio for death, 0.68; 99.73% CI, 0.47 to 0.997; P=0.0025). Updated analyses regarding progression-free survival were similar to those previously reported, with a median duration of 17.2 months in the durvalumab group and 5.6 months in the placebo group (stratified hazard ratio for disease progression or death, 0.51; 95% CI, 0.41 to 0.63). The median time to death or distant metastasis was 28.3 months in the durvalumab group and 16.2 months in the placebo group (stratified hazard ratio, 0.53; 95% CI, 0.41 to 0.68). A total of 30.5% of the patients in the durvalumab group and 26.1% of those in the placebo group had grade 3 or 4 adverse events of any cause; 15.4% and 9.8% of the patients, respectively, discontinued the trial regimen because of adverse events. CONCLUSIONS: Durvalumab therapy resulted in significantly longer overall survival than placebo. No new safety signals were identified.

AB - : During early development of a drug, in vivo studies precede or complement pharmacological bioassays in laboratory animals (in vivo studies). Carvacrol is a product with high therapeutic potential, which in vitro studies have been showing favorable results in different cellular models or methodological designs. Therefore, the objective was to conduct a systematic review to analyze pharmacological effects of carvacrol in in vitro studies. A comprehensive literature research using Science Direct, Scopus, MEDLINE-PubMed, Web of Science. SELECTION CRITERIA: Four databases were used (Internet sources), such as: National Library of Medicine (MEDLINE-PubMed), Science Direct, Web of Science and Scopus, using different combinations of the following keywords: carvacrol, drug therapy, therapeutic uses, in vitro study. The searches on databases were for studies conducted in the period up to and including September 2016. A total of 3,269 studies were initially identified, with only 31 meeting the inclusion criteria. The included studies showed a variety of in vitro models able to determine the properties of Carvacrol. Many mechanisms of action of Carvacrol were noted: antimicrobial effect (7 studies), bactericidal (4), bactericidal and antifungal (1), anti-inflammatory (4), anticancer (4), mutagenic activity (4), antioxidant (3), antifungal (3), antidepressant (1), modulator of nerve impulses (1) and immunological modulator (1). The In vitro studies with Carvacrol included in this review showed a diversity of models and confirmed the therapeutic potential of this product in relation to several diseases. PMID- 30280661 TI - Nutraceutical-based integrative medicine: Adopting a Mediterranean diet pyramid for attaining healthy ageing in veterans with disabilities. AB - Veterans with disability represent a big burden worldwide and often require long term rehabilitation. Unhealthy dietary and lifestyle habits, including smoke and alcohol abuse, are common in veterans. In the context of integrative medicine approaches, the "complementary and alternative medicine" has been suggested for the management of chronic diseases. However, the potential risk of interaction between herbal products, dietary supplements and drugs must be considered in veterans. The Mediterranean diet has been suggested as a natural, non pharmacological nutraceutical for healthy ageing. Although there is a broad consensus on the positive effect of plant foods consumption, the presence of glucosinolates, flavonoids and furanocoumarins in some plant foods and beverages must be taken into consideration owing to their potential interfering with drugs metabolism and bioavailability. Albeit seasonality could ensure the maintenance of the single dose of phytochemical below that at which adverse effects in some individuals genetically predisposed or unpleasant drug interactions in diseased subjects can occur, a personalized nutrition is recommended in veterans who are in treatment for comorbidities. Furthermore, sports practice can lead veterans with motor disabilities and mental impairments to excel in some disciplines, giving rise to the phenomenon of the Paralympics and the development of "recreational therapy". Moreover, outdoor lifestyle, through vitamin D synthesis, and conviviality, improving socialization, could account for the Mediterranean lifestyle health benefits. In this work we propose for veterans a Mediterranean Pyramid, which could be the basis for integrative medicine for veterans with disabilities, patient-centered approaches and interprofessional (including physical medicine and rehabilitation clinicians, pharmacists and nutritionists) interventions. PMID- 30280663 TI - Drug-drug interactions of P-gp substrates unrelated to CYP metabolism. AB - Background: Recent US Food and Drug Administration (FDA) draft guidance on pharmacokinetic drug-drug interactions (DDIs) has highlighted the clinical importance of ABC transporters B1 or P-glycoprotein (P-gp), hepatic organic anion transporting polypeptide transporters and breast cancer resistant protein because of their broad substrate specificity and the potential to be involved in DDIs. This guidance has indicated that digoxin, dabigatran etexilate and fexofenadine are P-gp substrate drugs and has defined P-gp inhibitors as those that increase the AUC of digoxin by ?1.25-fold in clinical DDI studies. However, when substrate drugs of both CYPs and P-gp are involved in DDIs, it remains that the mechanisms of DDIs will be quite ambiguous in assessing how much the CYPs and/or drug transporters partially contribute to DDIs. Objective: Since there are no detailed manuscripts that summarizes P-gp interactions unrelated to CYP metabolism, this article reviews the effects of potent P-gp inhibitors and P-gp inducers on the pharmacokinetics of P-gp substrate drugs, including digoxin, talinolol, dabigatran etexilate, and fexofenadine in human studies. In addition, the present outcome were to determine the PK changes caused by DDIs among P-gp substrate drugs without CYP metabolism in human DDI studies. Conclusion: Our manuscript concludes that the PK changes of the DDIs among P-gp drugs unrelated to CYP metabolism are less likely to be serious, and it appears to be convincing that the absences of clinical effects caused to the PK changes by the P-gp inducers is predominant compared with the excessive effects caused to those by the P-gp inhibitors. PMID- 30280664 TI - Survey of Drug Oxidation Activities in Liver and Intestine Microsomes of Individual Common Marmosets, a New Nonhuman Primate Animal Model. AB - BACKGROUND: Common marmosets (Callithrix jacchus) are potentially useful nonhuman primate models for preclinical studies. Information for major drug-metabolizing cytochrome P450 (P450) enzymes is now available that supports the use of this primate species as an animal model for drug development. Here, we collect and provide an overview of information on the activities of common marmoset liver and intestine microsomes with respect to 28 typical human P450 probe oxidations. RESULTS: Marmoset P450 2D6/8-dependent R-metoprolol O-demethylation activities in liver microsomes were significantly correlated with those of midazolam 1'- and 4 hydroxylations, testosterone 6beta-hydroxylation, and progesterone 6beta hydroxylation, which are probe reactions for marmoset P450 3A4/5/90. In marmosets, the oxidation activities of liver microsomes and intestine microsomes were roughly comparable for midazolam and terfenadine. Overall, multiple forms of marmoset P450 enzymes in livers and intestines had generally similar substrate recognition functionalities to those of human and/or cynomolgus monkey P450 enzymes. CONCLUSION: The marmoset could be a model animal for humans with respect to the first-pass extraction of terfenadine and related substrates. These findings provide a foundation for understanding individual pharmacokinetic and toxicological results in nonhuman primates as preclinical models and will help to further support understanding of the molecular mechanisms of human P450 function. PMID- 30280665 TI - Nanomedicine for gene delivery for the treatment of cardiovascular diseases. AB - Myocardial infarction (MI) is the most severe ischemic heart disease and directly leads to heart failure till death. Target molecules have been identified in the event of MI including increasing angiogenesis, promoting cardiomyocyte survival, improving heart function and restraining inflammation and myocyte activation and subsequent fibrosis. All of which are substantial in cardiomyocyte protection and preservation of cardiac function. To modulate target molecule expression, virus and non-virus-mediated gene transfer have been investigated. Despite successful in animal models of MI, virus-mediated gene transfer is hampered by poor targeting efficiency, low packaging capacity for large DNA sequences, immunogenicity induced by virus and random integration into human genome. Nanoparticles could be synthesized and equipped on purpose for large scale production. They are relatively small in size and do not incorporate into genome. They could carry DNA and drug within the same transfer. All of these properties make them an alternative strategy for gene transfer. In the review, we first introduce the pathological progression of MI. After concise discussion the current status of virus-mediated gene therapy in treating MI, we overview the history and development of nanoparticle-based gene delivery system. We point out the limitations and future perspective in the field of nanoparticle vehicle. Ultimately, we hope that this review could help to better understand how far we are with nanoparticle-facilitated gene transfer strategy and what obstacles we need to solve for utilization of nanomedicine in the treatment of MI. PMID- 30280666 TI - Stroke as a Cause of Death in Death Certificates of Patients with Dementia: A Cohort Study from the Swedish Dementia Registry. AB - INTRODUCTION: Patients with dementia may be at a higher risk for death from stroke. We aimed to describe characteristics of dementia patients that died from ischemic stroke (IS) in Sweden. METHODS: A retrospective longitudinal analysis of prospectively collected data of patients registered into the Swedish Dementia Registry was conducted. Data on causes of death, drugs and comorbidities were acquired from the Swedish nationwide health registers. Deaths were attributed to stroke if the death certificate contained stroke as a cause of death and the patient had a stroke registered in Riksstroke, the Swedish Stroke Register, in the year preceding death. Demographic data at the time of dementia diagnosis was compared between patients dying from IS and registered in Riksstroke, patients dying from IS without being registered in Riksstroke and those dying from other causes. RESULTS: Out of 49823 patients diagnosed with dementia between 2007 and 2014 in primary care or specialist clinics, 14170 (28.4%) had died by the end of 2014. Of these 1180 (8.3%) had IS in their death certificate, of which 459 (38.9%) had been registered in Riksstroke. In patients who died of IS the most common type of dementia was vascular dementia while those died from other causes were most often diagnosed with Alzheimer's dementia (AD). Patients who died from IS and were registered in Riksstroke had higher MMSE score compared to other groups. Patients who died from IS took more cardiovascular medications. There were no differences in the use of antipsychotics, antidepressants, acetylcholinesterase inhibitors, memantine, anxiolytics, or hypnotics between the groups. CONCLUSIONS: There was a relatively high number of patients who died from IS as shown in their death certificate but had not been registered in Riksstroke in the year before death. This creates concerns on the accuracy of death certificate stroke diagnoses, particularly for deaths taking place outside hospitals. PMID- 30280667 TI - Cardiovascular risk in perimenopausal women. AB - Cardiovascular disease, and particularly coronary heart disease (CHD), has a low incidence in premenopausal women. Loss of ovarian hormones during the perimenopause and menopause leads to a sharp increase in incidence. Although most CHD risk factors are common to both men and women, the menopause is a unique additional risk factor for women. Sex steroids have profound effects on many CHD risk factors. Their loss leads to adverse changes in lipids and lipoproteins, with increases being seen in low density lipoprotein (LDL) cholesterol and triglycerides, and decreases in high density lipoprotein (HDL) cholesterol. There is a reduction in insulin secretion and elimination, but increases in insulin resistance eventually result in increasing circulating insulin levels. There are changes body fat distributionwith accumulation in central and visceral fat which links to the other adverse metabolic changes. There is an increase in the incidence of hypertension and of type 2 diabetes mellitus, both major risk factors for CHD. Oestrogens have potent effects on blood vessels and their loss leads to dysfunction of the vascular endothelium. All of these changes resulting from loss of ovarian function contribute to the increased development of CHD. Risk factor assessment in perimenopausal women is recommended, thereby permitting the timely introduction of lifestyle, hormonal and therapeutic interventions to modify or reverse these adverse changes. PMID- 30280668 TI - HHIV Associated Neurodegenerative Disorders: A New Perspective on the Role of Lipid Rafts in Gp120-Mediated Neurotoxicity. AB - The implementation of combination antiretroviral therapy (cART) as the primary means of treatment for HIV infection has achieved a dramatic decline in deaths attributed to AIDS and the reduced incidence of severe forms of HIV-associated neurocognitive disorders (HAND) in infected individuals. Despite these advances, milder forms of HAND persist and prevalence of these forms of neurocognitive impairment are rising with the aging population of HIV infected individuals. HIV enters the CNS early in the pathophysiology establishing persistent infection in resident macrophages and glial cells. These infected cells in turn secrete neurotoxic viral proteins, inflammatory cytokines, and small metabolites thought to contribute to neurodegenerative processes. The viral envelope protein gp120 has been identified as a potent neurotoxin affecting neurodegeneration via indirect and direct mechanisms involving interactions with chemokine co-receptors CCR5 and CXCR4. This short review focuses on gp120 neurotropism and associated mechanisms of neurotoxicity linked to chemokine receptors CCR5 and CXCR4 with a new perspective on plasma membrane lipid rafts as an active participant in gp120 mediated neurodegeneration underlying HIV induced CNS pathology. PMID- 30280669 TI - Natural Starch in Biomedical and Food Industry: Perception and Overview. AB - Utilization of the native starch is increasing globally because of its wide distribution and occurring naturally. Starch is mainly abundant in tubers and food grains. Scientific research on starch is increasing in recent years due to their unique physiochemical and biomedical properties. Native starch is an emerging biopolymer and copolymer in front of biomedical and pharmaceutical areas due to their renewability, biocompatibility, biodegradability and their relative inexpensiveness. There is increasing interest in natural starches to design and produce diverse products due to their pertinent structural properties and non toxicity. Due to these attributes, these natural polymers are becoming functional core material for different applications including biomedical, construction materials, medicine industry, food industry and food supplements, food packaging, and carrier for active drugs. So in this paper, we mainly attempt to analyze the physicochemical attributions and the biomedical applications on native or non conventional starches obtained from the natural botanical sources. PMID- 30280670 TI - Iron Bisglycinate Chelate and Polymaltose Iron for the Treatment of Iron Deficiency Anemia: a Pilot Randomized Trial. AB - BACKGROUND: Iron deficiency anemia (IDA) is a major public health problem worldwide. Iron bisglycinate chelate (FeBC) and polymaltose iron (FeP) are used for the treatment of IDA and exhibit good tolerability with a low incidence of adverse effects. However, these compounds have important differences in their structures and bioavailability. OBJECTIVE: To compare the efficacy of oral supplementation with FeBC and FeP in anemic children. METHODS: In this double blind study, children aged 1 to 13 years who were diagnosed with IDA were randomly divided into two groups: i) FeBC, supplemented with iron bisglycinate chelate, and ii) FeP, supplemented with polymaltose iron (3.0 mg iron/kg body weight/day for 45 days for both groups). RESULTS: Both treatments resulted in significant increases in hemoglobin levels, mean corpuscular volume (MCV) and cell distribution width (RDW) and in a reduction of transferrin levels, relative to initial values. However, only FeBC treatment significantly increased ferritin and mean corpuscular hemoglobin (MCH) levels. A significant negative correlation was observed between the increase in ferritin and initial hemoglobin levels in the FeBC group, indicating that the absorption of FeBC is regulated by the body iron demand. CONCLUSION: These results provide preliminary evidence to suggest a greater efficacy of FeBC than FeP in increasing iron stores. PMID- 30280671 TI - 3D-QSAR and molecular docking studies on oxadiazole substituted benzimidazole derivatives: Validation of experimental inhibitory potencies towards COX-2. AB - ? Background: In past few decades, computational chemistry has seen significant advancements in design and development of novel therapeutics. Benzimidazole derivatives showed promising anti-inflammatory activity through the inhibition of COX-2 enzyme. ? Objective: The structural features necessary for COX-2 inhibitory activityfor a series of oxadiazole substituted benzimidazoles were explored through3D-QSAR, combinatorial library generation (Combi Lab) and molecular docking. ? Method: 3D-QSAR (using kNN-MFA (SW-FB) and PLSR (GA) methods) and Combi Lab studies were performed by using VLife MDS Molecular Design Suite. The molecular docking study was performed by using AutoDockVina. ? Results: Significant QSAR models generated by PLSR exhibited r2 = 0.79, q2 = 0.68 and pred_r2 = 0. 84 values whereas kNN showed q2 = 0.71 and pred_r2 = 0.84. External validation of developed models by various parameters assures their reliability and predictive efficacy. A library of 72 compounds was generated by combinatorial technique in which 11 compounds (A1-A5 and B1-B6) have shown better predicted biological activity than the most active compound 27 (pIC50 = 7.22) from the dataset. These compounds showed proximal interaction with amino acid residues like TYR355 and/or ARG120 on COX-2(PDB ID: 4RS0). ? Conclusion: The present work resulted in design of more potent benzimidazoles as COX-2 inhibitors with good interaction as compared to reference ligand. The results of the study may be helpful in the development of novel COX-2 inhibitors for inflammatory disorders. PMID- 30280672 TI - Broad Spectrum Peptide Vaccine Design against Hepatitis C Virus. AB - Hepatitis C virus infection is a global burden. Vaccination is the main proposed modality to control this disease. No peptide vaccine has been released to market due to weak cellular immune responses and the limitation of vaccine ability to induce humoral immune responses. Five predominated HCV subtypes in Indonesia (1a, 1b, 1c, 3a, and 3k) were aligned and the conserved regions were selected. All conserved regions were undergone epitopes prediction for class I HLA, class II HLA, and B cells. Twenty class I HLA ranging from HLA-A, HLA-B, to HLA-C were used to predict the potential epitopes by using NetMHCPan and IEDB. Eight HLA DRB1 and combination of 3 HLA-DQA1 and 5 HLA-DQB1 were utilized for Class II epitopes prediction by using NetMHCIIPan and IEDB. LBtope and IgPred were used to predict B cells epitopes. For Class I HLA, proteasome analysis was performed by NetCTL and stability of the epitopes to HLA binding was calculated by using NetMHCStabPan. All predicted epitopes were analyzed for antigenicity, toxicity, and stability. Population coverage was calculated for several best epitopes. Two best epitopes from E2 (Envelope 2) protein, GHRMAWDMMMNWSP and PALSTGLIHLHQN were selected as B cells and CD8+ T cell inducer. Other two peptides, LGIGTVLDQAETAG and VLVLNPSVAATLGF, taken from NS3 protein were selected as CD4+ T Cell inducer. This study suggested the utilization of all four peptides above to make a combinational peptide vaccine for in vivo study to prove its ability to induce secondary response to prevent HCV infection. PMID- 30280673 TI - Image-based QSAR model for prediction of P-gp inhibitory activity of epigallocatechin and gallocatechin derivatives. AB - BACKGROUND: Permeability glycoprotein (P-gp) is one of the cell membrane proteins that can pushed some drugs out of the cell and it causes drug tolerance and its inhibition can prevent drug resistant. OBJECTIVE: In this study, we used image based quantitative structure-activity relationship (QSAR) models to predict the P gp inhibitory activity of epigallocatechin and gallocatechin derivatives. METHODS: The 2D-chemical structures and their P-gp inhibitory activity were taken from literature. The pixels of images and their principal components (PCs) were calculated using MATLAB software. Principle component regression (PCR), artificial neural network (ANN) and support vector machine (SVM) approaches were used to develop QSAR models. Statistical parameters included the leave one out cross-validated correlation coefficient (q2) for internal validation of the models and R2 of test set, root mean square error (RMSE) and concordance correlation coefficient (CCC) were applied for external validation. RESULTS: Six PCs from image analysis method were selected by stepwise regression for developing linear and non-linear models. Non-linear models i.e. ANN (with the R2 of 0.80 for test set) were chosen as the best for the established QSAR models. CONCLUSION: According to the result of the external validation, ANN model based on image analysis method can predict the P-gp inhibitory activity of epigallocatechin and gallocatechin derivatives better than the PCR and SVM models. PMID- 30280674 TI - Synthesis, Anti-inflammatory Activity and Docking Studies of Some Newer 1,3 Thiazolidine-2,4-dione Derivatives as Dual Inhibitors of PDE4 and PDE7. AB - BACKGROUND: Phosphodiesterase 4 (PDE4) and phosphodiesterase 7 (PDE7), members of PDE superfamily, catalyse hydrolysis of cyclic adenosine monophosphate in pro inflammatory and immunomodulatory cells leading to increased inflammatory processes. Dual inhibitors of PDE4 and PDE7 are a novel class of drug candidates which can regulate pro-inflammatory as well as immune T-cell function and can be particularly useful in the treatment of a wide variety of immune and inflammatory disorders with less undesirable adverse effects. OBJECTIVE: The present research work was designed to synthesize and evaluate the anti-inflammatory activity as well as in silico docking studies of some newer substituted 1,3-thiazolidine-2,4 dione derivatives as dual inhibitors of PDE4-PDE7. METHOD: A new series of substituted 1,3-thiazolidine-2,4-dione derivatives was synthesized and evaluated for anti-inflammatory activity in animal models followed by docking studies to determine the binding interactions for the best fit conformations in the binding site of PDE4 and PDE7 proteins. RESULTS: Amongst the synthesized molecules, compounds 5 and 12 showed higher anti-inflammatory activity in the carrageenan induced rat paw oedema method. The in vivo experimental results were found to be in concordance with that of the in silico results. CONCLUSION: These molecules can act as the starting hits for the design of safe and effective dual inhibitors of PDE4 and PDE7 for the potential treatment of various inflammatory disorders. PMID- 30280675 TI - Integrin alpha6 (CD49f), The Microenvironment and Cancer Stem Cells AB - Cancer is a highly prevalent and potentially terminal disease that affects millions of individuals worldwide. Here, we review the literature exploring the intricacies of stem cells bearing tumorigenic characteristics and collect evidence demonstrating the importance of integrin α6 (ITGA6, also known as CD49f) in cancer stem cell (CSC) activity. ITGA6 is commonly used to identify CSC populations in various tissues and plays an important role sustaining the self renewal of CSCs by interconnecting them with the tumorigenic microenvironment. PMID- 30280676 TI - Recent biomedical applications on stem cell therapy: A brief overview. AB - The unique self-renewal and differentiation ability of stem cells drag the attention of many scientists and researchers towards the clinical application of stem cells. Stem cells are basically the normal living cells of multicellular organisms with some special ability to proliferate and transform into any kind of the body cells with their characteristic feature. Talking about human stem cells, it is originated from various sources like embryonic stem cells, somatic stem cells, hematopoietic stem cells, bone marrow stem cells, neural stem cells etc. which differs in their differentiation potency. On the basis of their potency they can be applied in treatment or regeneration of different cells. Stem cell therapy having very wide range application in treatment of various diseases. In this review article we have summarized the application of stem cell as regenerative medicine and treatment of chronic disorders. PMID- 30280677 TI - Stem cell-based therapies: A New ray of hope for diabetic patients. AB - Diabetes and its complications are a significant health concern throughout the globe. There are physiological differences in the mechanism of type-I and type-II diabetes and the conventional drug therapy as well as insulin administration seem insufficient to address the problem at large successfully. Hypoglycemic swings, frequent dose adjustments and resistance to the drug are major problems associated with drug therapy. Cellular approaches through stem cell based therapeutic interventions offer a promising solution to the problem. The need for pancreatic transplants in case of Type-I diabetes can also be by-passed/reduced due the formation of insulin producing beta cells via stem cells. Embryonic stem cells and (ESCs) and induced pluripotent stem cells (iPSCs), successfully used for generating insulin producing beta cells. Although many experiments have shown promising results with stem cells in vitro, their clinical testing still needs more exploration. The review attempts to bring into light clinical studies favoring the transplantation of stem cells in diabetic patients with an objective of improving insulin secretion and improving degeneration of different tissues in response to diabetes. It also focuses on the problems associated with successful implementation of the technique and possible directions for future research. PMID- 30280678 TI - Theranostic platforms proposed for cancerous stem cells: A review. AB - It is a near-to-impossible not to accept that cancer takes position as the main cause of global burden of disease, for it is hard to ignore the outnumbered people dying from cancer. Looking at the statistics proves that progress in cancer therapy is always beyond cancer in a race of pessimism about the future; for various kinds of cancers yearly cause death in the world, whereas the conventional and even modern therapies often exhibit lack of reliability in treatment of cancer. In principal, various reasons are identified for cancer resistance and recurrence. Recognizing the cells/tissue from which cancer takes origin enables its early detection, and optimistically saying protection of patients against death. It has been recognized that cancer stem cells are responsible for cancer cell proliferation and metastasis. Conventional therapies cannot eradicate the cancer stem cell; therefore, cancer recurrence is unavoidable. In this regards, designing smart platforms with specific properties is an essential step in cancer treatment. Theranostic platforms have been facilitated the cancer diagnosis and treatment, simultaneously. In this respect, several sorts of smart materials have been designed to detect and cure the cancer. Cancer stem cell as a root of the cancerous tumor should be eradicated to achieve the complete treatment; hence, cancer stem cell mechanism must be known precisely to architect the appropriate platform making possible to encounter with cancer stem cell. In this review paper, various therapeutic and diagnostic techniques of cancerous stem cell are discussed to pave a way for designing proper platforms for cancer eradication. PMID- 30280679 TI - Lifestyle patterns as a modifiable risk factor for late-life cognitive decline: a narrative review regarding dementia prevention. AB - BACKGROUND: Dementias due to neurodegenerative disorders and more specifically, Alzheimer's disease (AD) are the most frequent of all diseases within the industrialized world. Besides this alarming fact, it is noted too that almost three-quarter of people with AD reside in low or middle-income nations. In recent years, cognitive and behavioral neuroscientists have focused on a possible correlation between environmental agents and genetic risk factors for these dementias. METHOD: In this narrative review, a close review of Medical Literature Analysis and Retrieval System was conducted. The authors aimed at analyzing possible interactions between lifestyle patterns and major risk factors responsible for cognitive decline and dementia, considering that the prevention or treatment of midlife modifiable risks may possibly reduce population-wide late life pathological neurodegeneration. RESULTS: This review focuses on modifiable risk factors for late-life cognitive decline. A growing number of studies have indicated that the impact of genetics and epigenetic factors on dementia risk is dependent on different lifestyle factors, ranging from leisure activities and nutritional habits, through to social interaction and toxic exposure. CONCLUSION: Despite all evidence regarding modifiable risk factors possibly reducing the risk of developing dementia in later life, many unanswered questions remain regarding the direct influence of these variables in later life. People who regularly and actively participate in different lifelong activities (social, cultural and intellectual) do tend to perform better on formal cognitive tests, experience fewer cognitive complaints, and are less likely to develop neurodegenerative disorders. PMID- 30280680 TI - Hyperkinetic disorder in a community service for people with intellectual disability. AB - BACKGROUND: There appears to be a higher rate of prevalence of hyperkinetic disorder in the intellectual disability (ID) population, although there is a large variability in rates in previous studies. Hyperkinetic disorder can be a challenge to diagnose in a population with ID and can present a barrier to the development of the activities of daily living in an already vulnerable population. OBJECTIVES: Our objective was to examine the point prevalence of hyperkinetic disorder in the ID population in a community ID service and also to determine the prevalence of hyperkinetic disorder based on the level of ID. METHODS: A cross-sectional review of the Online Information Service 'OLIS' database was undertaken to establish the total number of patients with ID and those with comorbid hyperkinetic disorder. The overall point prevalence and prevalence based on the level of ID was calculated from the collected data. RESULTS: The point prevalence of hyperkinetic disorder in the population with ID was similar to that found in studies in the general population at 3.1% in adults and 32.6% in children. When divided by the level of disability, the calculated point prevalence in both adults and children was highest in the population with mild ID and decreased as the level of disability increased. CONCLUSION: This report contributes to previous research establishing the rates of hyperkinetic disorder in an ID population and establishes the point prevalence of hyperkinetic disorder in individuals diagnosed with ID in a clinical sample. PMID- 30280681 TI - Climatic influences on the mortality of sheep during long-distance sea transport. AB - Research on the causes of sheep death in sea voyages from Australia to the Middle East is limited, in particular little is known about the influence of climatic factors. Mortality data from 417 shipments of sheep exported over an 11-year period (November 2004 to June 2015) were modelled retrospectively to determine associated climatic factors. The statistical analysis were performed for both the full data set with 417 voyages based on actual and estimated departure and arrival dates and a restricted data set with 71 voyages based on actual dates. The results of the full data set demonstrated a seasonal mortality pattern, with more deaths occurring on sea voyages leaving Australia in the southern hemisphere winter or spring than those departing in Australian summer or autumn. Heat stress and inadequate fat mobilisation for energy supply when sheep are inappetant on shipments may explain this seasonality. Based on these two models, the voyage and weather factors associated with sheep mortalities included departure year, autumn departure in the southern hemisphere, voyage duration, single or multiple loading port(s), weekly mean dry bulb temperature and wind speed at departure ports, and humidity at destination ports. Significant correlations were observed between weather variables at the departure ports in the Australian winter and a high sheep mortality rate during voyages. This, together with the anticipated increased heat stress risk as a result of climate change, suggests that there could be review of the trade from Australia in the southern hemisphere winter. The influence of weather at the departure ports should be considered in sheep mortality prediction models, especially Australia's heat stress risk assessment model. PMID- 30280682 TI - Mitochondrial activity and cytoskeleton organization in three pronuclei oocytes after intracytoplasmic sperm injection. AB - SummaryDigyny, the presence of a third pronucleus due to the failure of second polar body extrusion, is problematic after intracytoplasmic sperm injection (ICSI) practices. Mitochondria have critical roles such as production of adenosine triphosphate (ATP) and regulation of Ca2+ homeostasis during oocyte maturation, fertilization and the following development, while the regulation of meiotic spindle formation, chromosome segregation, pronuclear apposition and cytokinesis is closely associated with the cytoskeleton. In this study, mitochondrial membrane potential, distribution of F-actin and gamma-tubulin, and the ultrastructure of three pronuclear (3PN) oocytes were investigated. 3PN oocytes after ICSI procedure were taken from patients who were enrolled in assisted reproduction programmes. For mitochondrial membrane potential analysis, fresh oocytes stained with the mitochondrial membrane potential probe JC-1, were evaluated under fluorescence microscopy. The mitochondrial membrane potential of three pronuclear oocytes showed similar results to normal zygotes. gamma-Tubulin was stained strongly at the subplasmalemmal domain and microfilaments were localized at the cortical, but not the perinuclear, area. Cytoplasmic halos were moderately or not detected by electron microscopy; lipofuscin granules, degenerated mitochondria, and multilamellated bodies were seen in the ooplasm. Immunohistochemistry and electron microscopic findings suggested that mitochondrial membrane potential has no direct effect on second polar body extrusion. This abnormality can be associated with an altered cytoskeleton due to poor oocyte quality. PMID- 30280683 TI - Estimating development and temperature thresholds of Ephestia kuehniella: toward improving a mass production system. AB - The development of the Mediterranean flour moth, Ephestia kuehniella (Zeller), was evaluated at 10, 15, 17.5, 20, 22.5, 25, 27.5, 30 and 32.5 degrees C with no lighting. None successfully completed development at 10 and 32.5 degrees C. The total development time from egg to adult emergence was 164, 140, 98, 76, 61, 62 and 50 days, respectively, at the remaining temperatures. The developmental rate of E. kuehniella was described by the common linear model and six non-linear models. The lower temperature threshold for the immature stages and the thermal constant for E. kuehniella were 9 degrees C and 1111 degree-days (DD) to complete development from egg to newly emerged adult. Non-linear models estimated the lower and upper thermal thresholds (Tmin and Tmax) and optimal temperature (Topt). The values of Tmax calculated by three nonlinear models ranged from 34 degrees C to 46 degrees C; Topt for each stage of development varied from 24 and 31 degrees C, consistent with the temperature (30 degrees C) at which the most rapid development occurred. Information on the threshold temperatures for development and thermal requirements can be utilized to predict E. kuehniella population dynamics and phenology and to evaluate optimal temperature conditions for mass rearing in stored products. PMID- 30280684 TI - Maturational gene upregulation and mitochondrial activity enhancement in mouse in vitro matured oocytes and using granulosa cell conditioned medium. AB - SummaryThe high miscarriage rates that result following transfer of embryos derived from in vitro maturation (IVM) of oocytes necessitate improvements in the processes involved. This study aimed to improve the quality of in vitro matured oocytes using granulosa cell conditioned medium (GCCM) as the culture medium. In this work, germinal vesicle (GV)-stage oocytes from NMRI mice were collected and cultured using three types of culture medium: Base medium (BM) (control), 50% granulosa cell conditioned medium (GCCM50) and 100% GCCM (GCCM100). After IVM, the mitochondria activity potential and viability of metaphase II (MII) oocytes were evaluated by JC-1 and trypan blue staining, respectively. Maturational gene expression levels of CyclinB1, Cdk1 and Gdf9 in the control, GCCM50 and GCCM100 samples were analyzed using real-time polymerase chain reaction (PCR). The viability rate of in vitro matured oocytes was highest in the GCCM50 group. JC-1 staining showed that GCCM50 enhances mitochondrial activity more than the other groups (P < 0.05). Gene expression levels of Cdk1 and Gdf9 were higher in the group with GCCM50 treatment, than in the control and GCCM100 groups (P < 0.05), while the expression level of CyclinB1 did not differ among the groups. The results indicated that a 50% concentration of GCCM in combination with BM components enhanced MII and viability rates and mitochondria activity of mouse immature oocytes.

PMID- 30280688 TI - Uptake and effectiveness of influenza vaccine in those aged 65 years and older in the United Kingdom, influenza seasons 2010/11 to 2016/17. AB - BackgroundIn 2016/17, seasonal influenza vaccine was less effective in those aged 65 years and older in the United Kingdom. We describe the uptake, influenza associated mortality and adjusted vaccine effectiveness (aVE) in this age group over influenza seasons 2010/11-2016/17. Methods: Vaccine uptake in 2016/17 and five previous seasons were measured using a sentinel general practitioners cohort in England; the test-negative case-control design was used to estimate pooled aVE by subtype and age group against laboratory-confirmed influenza in primary care from 2010-2017. Results: Vaccine uptake was 64% in 65-69-year-olds, 74% in 70-74 year-olds and 80% in those aged 75 and older. Overall aVE was 32.5% (95% CI: 11.6 to 48.5); aVE by sub-type was 60.8% (95% CI: 33.9 to 76.7) and 50.0% (95% CI: 21.6 to 68.1) against influenza A(H1N1)pdm09 and influenza B, respectively, but only 5.6% (95% CI: - 39.2 to 35.9) against A(H3N2). Against all laboratory confirmed influenza aVE was 45.2% (95% CI: 25.1 to 60.0) in 65-74 year olds; - 26.2% (95% CI: - 149.3 to 36.0) in 75-84 year olds and - 3.2% (95% CI: - 237.8 to 68.5) in those aged 85 years and older. Influenza-attributable mortality was highest in seasons dominated by A(H3N2). Conclusions: Vaccine uptake with non adjuvanted, normal-dose vaccines remained high, with evidence of effectiveness against influenza A(H1N1)pdm09 and B, though poor against A(H3N2), particularly in those aged 75 years and older. Forthcoming availability of newly licensed vaccines with wider use of antivirals can potentially further improve prevention and control of influenza in this group. PMID- 30280690 TI - Toxoplasma gondii IgG Seroprevalence in Patients with HIV/AIDS. AB - OBJECTIVE: Toxoplasmosis is a common opportunistic infection in patients with HIV/AIDS and may cause life-threatening clinical courses, such as encephalitis and pneumonia. METHODS: Patients admitted between January 2006 and August 2017 with anti-HIV positivity confirmed by Western blotting were included in the study. Demographic data, CD4+ T-lymphocyte counts, and Toxoplasma gondii IgG/IgM levels were retrospectively obtained from patient records. RESULTS: T. gondii IgM positivity was not detected in patients, whereas T. gondii IgG positivity was detected in 267 (43.5%) patients. The T. gondii IgG positivity rate was 37.6% in men who had sex with men (MSM) and 48.4% in heterosexual patients. Furthermore, 42.6% of MSM and 21% of heterosexual patients were university graduates, of which T. gondii IgG positivity was detected in only 33.6% of MSM patients and 42.3% of heterosexual patients. CONCLUSION: In our study, high seronegativity was remarkable in MSM patients, particularly those who were highly educated, thus emphasizing the importance of prevention of primary infection in seronegative patients; necessity of prophylaxis in appropriate patients due to encephalitis, which has a high mortality rate and almost always develops after a latent infection; and necessity of screening for toxoplasmosis seropositivity at the time of diagnosis. PMID- 30280687 TI - The shift in rabies epidemiology in France: time to adjust rabies post-exposure risk assessment. AB - The epidemiology of rabies in France and western Europe has changed during the past 22 years. In France, rabies in non-flying terrestrial mammals was declared to be eliminated in 2001, and the risk of rabies is now limited to contact with bats, rabid animals illegally imported from rabies-enzootic countries and traveller exposure in enzootic areas. We analysed the epidemiology of rabies in France from 1995 to 2016, describing and analysing data on human rabies surveillance as well as data on post-exposure prophylaxis (PEP) collected from the network of French antirabies clinics. Over the study period, seven individuals were diagnosed with rabies in France, all of whom were infected outside mainland France. PEP data analysis revealed an expected overall decrease in PEP administration for individuals exposed in mainland France, but there was still overuse of anti-rabies drugs, given the very low epidemiological risk. On the other hand, a significant increase in PEP delivered to individuals exposed abroad was evidenced. These epidemiological trends indicate that clear guidelines should be provided to support physicians' efforts to adjust rabies risk assessment to the evolution of the epidemiological situation. PMID- 30280689 TI - Transmission of toxigenic Corynebacterium diphtheriae by a fully immunised resident returning from a visit to West Africa, United Kingdom, 2017. AB - In early 2017, a United Kingdom (UK)-born person in their 20s presented with a skin ulcer on the foot 3 weeks after returning from Ghana. The patient had last received a diphtheria-containing vaccine in 2013, completing the recommended course. MALDI-TOF of a cutaneous swab identified Corynebacterium diphtheriae. Real-time PCR ascertained the species and presence of the diphtheria toxin gene. An Elek test confirmed toxigenicity. The isolate was macrolide sensitive and penicillin resistant. The local Public Health England (PHE) Health Protection Team obtained the patient's clinical history and traced contacts to inform appropriate public health action. One close contact (in their early 80s with uncertain immunisation status who had not recently travelled) had a positive throat swab for toxigenic C. diphtheriae and reported a history of mild coryzal symptoms. Multilocus sequence typing revealed that strains from the index case and contact had Sequence Type 463. Diphtheria is extremely rare in the UK due to high vaccine coverage and this is the first documented transmission in 30 years. Clinicians and laboratory staff should remain highly suspicious of lesions in overseas travellers, even when patients are fully vaccinated. Older individuals who might not have completed a full immunisation course may have higher diphtheria susceptibility. PMID- 30280691 TI - Intestinal Protozoa in Hiv-Infected Patients: A Retrospective Analysis. AB - OBJECTIVE: Intestinal parasitic infections are common in immunodeficient patients. In developing countries, the incidence of diarrhea due to parasitic infections in HIV (human immunodeficiency virus)-positive individuals is reported to be over 90%. The present study aimed to investigate the presence of intestinal protozoa in HIV-positive patients with gastrointestinal complaints. METHODS: The fecal samples of 65 HIV-positive patients (14 women, 51 men) were included. Clinical data obtained from patients' files and laboratory results were retrospectively scanned using laboratory information system. Age, sex, parasite positivity, CD4+ count, HIV RNA level, and antiretroviral therapy information were recorded. RESULTS: Fourteen Cryptosporidium spp. (21.5%), 2 Cyclospora spp. (3.1%), 7 Blastocystis spp. (10.8%), and 1 Cryptosporidium spp.+Blastocystis spp. (1.5%) were detected. The median duration of antiretroviral treatment was 3 months and 12 months in patients with and without parasites in fecal samples, respectively. The duration of antiretroviral treatment was significantly higher in non-infected patients (p=0.002). No significant correlations were found between parasite presence and CD4+ T cell counts or HIV RNA levels. CONCLUSION: Our findings suggest that positive effects of antiretroviral therapy on the immune system of HIV-infected patients reduce the risk of intestinal parasitic infection, and thus, this treatment may play an important role in protection. PMID- 30280692 TI - Prediction of Cutaneous Leishmaniasis Epidemiology in Mersin Using Ecological Niche Modeling. AB - OBJECTIVE: In our study, we aimed to develop an ecological niche model showing current distribution of cutaneous leishmaniasis (CL) by using location information on 630 cases of CL reported in the Mersin province between 2005 and 2015 and bioclimatic and environmental variables. METHODS: The ecological niche model was based on interpretation of patient locations and climatic data entered in geographical information systems and maximum entropy databases. RESULTS: In the model produced for the Mersin province, the area under the curve was calculated as 0.918. Also, the mean temperature of the driest quarter (BIO9), mean temperature of the warmest quarter (BIO10), and maximum temperature of the warmest month (BIO5) were determined as climatic factors that are most effective for CL distribution. CONCLUSION: There is a relationship between distribution of CL and climatic factors in the Mersin province. The developed model will contribute to better understanding of epidemiology and control of vector-borne diseases by authorities in the ministry of health. PMID- 30280693 TI - Light Microscopy and Scanning Electron Microscopy of Colpocephalum nanum Piaget, 1890 (Phthiraptera: Amblycera: Colpocephalidae). AB - OBJECTIVE: The aim of this study was to examine the morphological characteristics of Colpocephalum nanum (C. nanum) Piaget, 1890 using light microscopy (LM) and scanning electron microscopy (SEM). METHODS: For this purpose, the C. nanum specimens collected from long-legged buzzards, Buteo rufinus (B. rufinus) (Accipitriformes: Accipitridae), in Turkey were examined under LM and SM for morphological characteristics. The specimens were fixed and kept in 70% ethanol, cleared and mounted on the slides in Canada balsam. They were examined for morphological characteristics under LM. Some of the samples were put in a plate on absorbing paper and kept overnight, for ether to evaporate. These samples were mounted on aluminum stubs to study the ventral surface by placing them on their dorsal or ventral surface on double-sided adhesive tape. They were sputter-coated three times with gold, each time for approximately 7 minutes and later viewed using SEM (Zeiss SUPRA 55 VP FE-SEM and Zeiss EVO lS 10). RESULTS: Parts of the specimens were photographed, and the obtained data about morphological characteristic were evaluated in detail. CONCLUSION: The LM and SEM photos of C. nanum were compared, and information about the important criteria for diagnosis and other morphological characteristics was obtained. PMID- 30280694 TI - Insecticidal, Oxidative, and Genotoxic Activities of Syzygium aromaticum and Eucalyptus globulus on Culex pipiens Adults and Larvae. AB - OBJECTIVE: The wide-reaching Culex pipiens has long been a public apprehension. Combating serious vector-borne diseases requires the use of insecticides effective against both humans and the ecosystem. The wide variation of botanicals that nature has to offer tempts researchers to study their interactions with the insects. Environment-friendly insecticides light up hope for maintaining ecological balance and pollution mitigation. This study aimed at evaluating the insecticidal, oxidative, and genotoxic activities of eucalyptus and clove oils on C. pipiens adults and larvae. METHODS: The chemical composition of essential oils was determined via gas chromatography/mass spectrometry. The bioassay was performed, with eucalyptus oil showing the highest toxicity index (LC50 of 0.108% after 24 h in adults and LC50 of 0.014% after 48 h in larvae). RESULTS: Fumigation effects showed Eucalyptus to have higher toxicity than clove oil, with an LC50 of 0.108% and 0.014% after 24 h and 48 h, respectively, in adults and larvae. The effect of tested oils on the activities of glutathione peroxidase, catalase, and superoxide dismutase varied with increasing oil concentrations. The genotoxic effects of the tested oils were dose-dependent, with an increase of all comet parameters compared with those in the control. CONCLUSION: The tested oils showed encouraging potentiality as green insecticides in combating C. pipiens. PMID- 30280696 TI - Myiasis Phenomenon in a Patient Receiving Maggot Debridement Therapy. AB - OBJECTIVE: Classical treatment was administered on the wound on the left foot of the patient, but no improvement was observed. When advised to undergo amputation, the patient came to the wound care unit to treat the larval wound. It was observed that the wound had been wormed while the patient was undergoing larval treatment. Interestingly, this incidental encounter was thought to be appropriate for case presentation. METHODS: The larvae seen in the left hand of the patient were removed using forceps and sent to a laboratory. The larvae as well as adult flies obtained from them were examined directly and stereomicroscopically, their photographs were captured, and they were typed. RESULTS: The larvae in the third stage and adult flies were identified as Sarcophaga sp. CONCLUSION: Hygiene deficiency, inadequate sanitation, and improper wound care are important factors responsible for myiasis formation. We believe that myiasis can be avoided if adequate sanitation and hygiene and appropriate and regular wound care are provided. PMID- 30280695 TI - Molecular Characterization of Myiasis-Causing Moth Flies (Diptera: Psychodidae). AB - OBJECTIVE: The aim of this study is to examine the molecular characterization of moth flies (Diptera: Psychodidae) based on their mitochondrial DNA sequences and determine the vectorial potential and damage caused by moth flies in future researches. METHODS: A total of 240 adult moth flies were collected from toilet, bathroom, and basement walls of houses from different locations of the Kayseri region between May 2016 and April 2017. The polymerase chain reaction (PCR) analyses were performed using primer pairs, specificaly targeting the mitochondrial cytochrome oxidase c subunit I (mt-COI) gene of adult flies. RESULTS: In total, five isolates were gel purified and sequenced for molecular characterization and phylogenetic analyses. Two species, namely Telmatoscopus albipunctatus (ERU-Telmatos3 and ERU-Telmatos6) and Psychodidae sp. (ERU Psycho1,4,5), were successfully identified with the sequence alignment of isolates. According to the phylogenetic analysis, it was determined that the ERU Telmatos3 and ERU-Telmatos6 isolates are clustered in the haplogroup A, while the ERU-Psycho1,4,5 isolate was clustered within the haplogroup B. The ERU-Psycho1 isolate was characterized as a new haplotype within the haplogroup B. CONCLUSION: This study represents the first molecular characterization and phylogenetic status of moth flies in Turkey. The obtained findings should be the first step in the future investigation based on detecting the transmission of bacterial pathogens by moth flies.

AB - Toxoplasma gondii is an obligatory intracellular protozoon parasite that causes toxoplasmosis in humans and all warm-blooded animals. In this study, we aimed to investigate the presence of T. gondii DNA in a Eurasian badger (Meles meles) that was found dead in the wildlife area of Izmir. According to the results of real time polymerase chain reaction, T. gondii REP gene was found to be positive in the Eurasian badger brain homogenate. In conclusion, Eurasian badger, a known carnivore, can be a potential source of toxoplasmosis in the natural settings of Izmir, Turkey. PMID- 30280698 TI - Importance of spin current generation and detection by spin injection and the spin Hall effect for lateral spin valve performance. AB - Lateral spin valves are attractive device geometries where functional spin currents can be generated and detected by various mechanisms, such as spin injection and the direct and the inverse spin Hall effect. To understand the mechanisms behind these effects better, as well as their potential for application in devices, we combine multiple mechanisms in multi-terminal Pt-Py-Cu lateral spin valves: we generate pure spin currents in the copper spin conduit both via the spin Hall effect in platinum and electric spin injection from permalloy and detect signals both via conventional non-local detection and via the inverse spin Hall effect in the same device at variable temperatures. Differences are observed, which we explain by the different spin injection and detection mechanisms, revealing their importance for the temperature dependence, which is not just governed by the spin transport in the conduit as previously claimed. By determining a different sensitivity of the observed effects on the interfaces, we highlight the importance of the exact current path for the device operation. PMID- 30280699 TI - Prevascularized bladder acellular matrix hydrogel/silk fibroin composite scaffolds promote the regeneration of urethra in a rabbit model. AB - OBJECTIVE: To evaluate the effects of urethral regeneration with prevascularized bladder acellular matrix hydrogel (BAMH)/silk fibroin (SF) composite scaffolds in a rabbit model. MATERIALS AND METHODS: BAMH/SF and collagen Type I hydrogel/SF (CH/SF) scaffolds were prepared and the structure of the scaffolds was assessed using scanning electron microscopy. BAMH/SF, CH/SF and SF scaffolds were incubated in the omentum of male rabbits for two weeks and then harvested for repairing autologous urethral defects. Histological analysis of the incubated scaffolds was performed to evaluate the neovascularization capacity, and the outcomes of urethroplasty were evaluated at one and three months post operatively. RESULTS: The composited scaffolds were composed of a highly porous BAMH or CH buttressed by compact SF outer layer. The histological analysis of the incubated BAMH/SF revealed a signifcant increase of the neovascularization among three groups after a two-week incubation. At three months, the urethra maintained wide caliber in the BAMH/SF group. Strictures were found in the CH/SF and SF groups. Histologically, at one month, intact and multilayer epithelium occurred in the BAMH/SF group, and one layer epithelium was found in the CH/SF and SF groups. However, there was similar epithelial regeneration in BAMH/SF and CH/SF groups at three months (p > 0.05). Comparisons of smooth muscle content and vessel density among the SF, CH/SF and BAMH/SF revealed a significant increase at each time point (p < 0.05). CONCLUSION: Our results demonstrate that incubated BAMH/SF promote neovascularization, and prevascularized BAMH/SF promote the regeneration of the urethral epithelium and smooth muscle, which indicates its potential for urethral reconstruction. PMID- 30280700 TI - Unconventional field-effect transistor composed of electrons floating on liquid helium. AB - We report on an unconventional macroscopic field effect transistor composed of electrons floating above the surface of superfluid helium. With this device unique transport regimes are realized in which the charge density of the electron layer can be controlled in a manner not possible in other material systems. In particular, we are able to manipulate the collective behavior of the electrons to produce a highly non-uniform, but precisely controlled, charge density to reveal a negative source-drain current. This behavior can be understood by considering the propagation of damped charge oscillations along a transmission line formed by the inhomogeneous sheet of two-dimensional electrons above, and between, the source and drain electrodes of the transistor. PMID- 30280701 TI - Surface states of gapped electron systems and semi-metals. AB - With a generic lattice model for electrons occupying a semi-infinite crystal with a hard surface, we study the eigenstates of the system with a bulk band gap (or the gap with nodal points). The exact solution to the wave functions of scattering states is obtained. From the scattering states, we derive the criterion for the existence of surface states. The wave functions and the energy of the surface states are then determined. We obtain a connection between the wave functions of the bulk states and the surface states. For electrons in a system with time-reversal symmetry, with this connection, we rigorously prove the correspondence between the change of Kramers degeneracy of the surface states and the bulk time-reversal Z 2 invariant. The theory is applicable to systems of (topological) insulators, superconductors, and semi-metals. Examples for solving the edge states of electrons with/without the spin-orbit interactions in graphene with a hard zigzag edge and that in a two-dimensional d-wave superconductor with a ([Formula: see text]) edge are given in appendices. PMID- 30280702 TI - Protein refractive index increment is determined by conformation as well as composition. AB - The refractive index gradient of the eye lens is controlled by the concentration and distribution of its component crystallin proteins, which are highly enriched in polarizable amino acids. The current understanding of the refractive index increment ([Formula: see text]) of proteins is described using an additive model wherein the refractivity and specific volume of each amino acid type contributes according to abundance in the primary sequence. Here we present experimental measurements of [Formula: see text] for crystallins from the human lens and those of aquatic animals under uniform solvent conditions. In all cases, the measured values are much higher than those predicted from primary sequence alone, suggesting that structural factors also contribute to protein refractive index. PMID- 30280703 TI - Torsion-induced vortex switching and skyrmion-like state in ferroelectric nanodisks. AB - The controllability of vortex state in ferroelectric nanodisks under the effect of external torsion is investigated in this work based on phase-field simulation. We discover a novel Bloch skyrmion-like state in ferroelectric nanodisks due to the combining effect of the torsion and the depolarization field. Moreover, a new strategy is proposed to achieve deterministic switching of the vortex chirality in the ferroelectric nanodisks. On the one hand, if a fixed external electric field is applied to the nanodisk, the vortex chirality can be switched by the torsion force. On the other hand, if we apply a fixed torsion force to the nanodisk, the vortex chirality can be readily switched by an external electric field. The feasibility of both mechanical and electrical switching of the vortex in the ferroelectric nanodisks is based on the trilinear coupling between the toroidization, polarization and shear strain of the system. The influences of temperature, electric field, torsion, and size of the nanodisk on the control of the vortex state are further revealed. Our findings shed light on the practical control and application of ferroelectric dipole vortices. PMID- 30280704 TI - Role of gut inhabitants on vectorial capacity of mosquitoes. AB - Mosquito-borne diseases are spreading at an alarming rate. Globally millions of deaths occur due to the diseases transmitted by mosquitoes, next to AIDS and tuberculosis. Several methods have been used to control these vectors and the diseases caused by them. Earlier studies have shown the potential role of mosquito gut inhabitants on disease transmission. Their findings can be used as an innovative approach for devising strategies to modify the survival of mosquitoes by reducing their lifespan, reproduction and disease transmission abilities. In this study, microbiome of the three genera of mosquitoes, namely Aedes, Anopheles, and Culex along with their vectorial capacity have been reviewed for assessing their role in mosquito control and transmission. Relevant articles were accessed using different databases, including LILACS, Embase, Science Direct and PubMed from inception to June 2017. The search keywords included "Aedes", "Anopheles", "Culex", "gut inhabitants", "vectors", and "mosquito". The titles, abstract, and keywords of the retrieved articles were screened, and eligible research articles were sorted. The review indicates that paratransgenesis may be considered as a versatile and effective strategy to eradicate the spurt of mosquito transmitting diseases. Enterobacter species is the most common type of gram-negative bacteria associated with the gut of all the three genera of mosquitoes. It was found to have a beneficial effect on humans as it helps in destroying dreadful disease-transmitting vectors. These symbiotic qualities of the microbes need to be thoroughly investigated further to reveal their antipathogenic effect on the vector. PMID- 30280705 TI - Predictive and diagnostic test accuracy of ultrasonography in differentiating severe dengue from nonsevere dengue. AB - Diagnosing severe dengue from those who do not develop complication is important to prevent death. The objective of this systematic review was to evaluate the diagnostic test accuracy of ultrasonography in differentiating severe dengue from nonsevere dengue; and to assess if ultrasonography/ultrasound can be used as a predictive (screening) and diagnostic tool in the course of dengue infection. An electronic search was conducted in different databases via OvidSP platform. The included studies were cohort studies between 1995 and 2016 wherein cases were confirmed by dengue blood test. Severity of dengue was assessed and compared using standard WHO references. The methodological quality of the paper was assessed by two independent reviewers by using QUADAS-2 tool. In total 12 studies were included in this review after suitable screening. Overall, the studies included had a low and unclear risk of bias. Seven out of nine studies that compared severe dengue and nonsevere dengue, performed an ultrasonography on gallbladder (wall thickness cutoff-3 mm) with a sensitivity of 24.2-100% and a specificity of 13.2-98.7%. Other parameters such as splenic subcapsular fluid collection, pericardial fluid and hepatic subcapsular fluid collection had a specificity of >90%, though the sensitivity was poor. There were insufficient evidence that ultrasonography is able to differentiate severe dengue from nonsevere dengue accurately. The predictive and diagnostic value of ultrasonography could not be concluded due to insufficient reporting on the temporality of the ultrasonography performed with regard to the diagnosis. However, it might serve as an adjunct investigation to support the clinical diagnosis. PMID- 30280706 TI - Transcriptional responses of attractin gene in the mosquito Anopheles culicifacies: A synergistic neuro-olfactory regulation. AB - Background & objectives: Attractin, is a large multi-domain protein which has regulatory functions in multiple physiological processes and thus have strong therapeutic potential. In invertebrates, it was first identified as a water-borne protein pheromone that plays important role in chemical communication and coordinates reproductive activities. But its role in mosquitoes/insects remains unknown. Our unexpected discovery of attractin homolog from the olfactory tissue of Anopheles culicifacies mosquito prompted us to investigate the possible role of Ac-attractin (Ac-atrn) in diverse behavioural responses, e.g. feeding, mating and other non-genetic stresses. Methods: A homology search analysis was performed to identify the full length attractin (Ac-atrn) gene of Anopheles culicifacies mosquito. To unravel its molecular function during external and internal stresses, extensive real-time PCR was performed in the neuro-olfactory tissues of the adult mosquitoes as well as in the larval stages. Further, a behavioural assay was conducted to elucidate its role in mosquitoes mating behaviour. Results: The results indicated that Ac-atrn is a 3942 bp long transcript which encodes a 1313 amino acid protein, having multiple domains including CUB, EGF, Keltch, etc, with 80-90% homology to other insect/mosquito homologs. Ac-atrn gene was dominantly expressed in the young larvae and its expression was elevated in response to the fresh food supply in the starved larvae. Cold stress temporarily arrested the expression of Ac-atrn gene. In case of adult mosquitoes, olfactory and brain tissue showed relatively higher expression of Ac-atrn than reproductive organs. Although, starvation did not yield significant changes in olfactory tissues, but aging and nutritional stress modulated Ac-atrn expression in the brain tissue. Furthermore, a circadian rhythm dependent change in the expression of Ac-atrn of virgin and mated mosquitoes (both sexes), indicates that Ac-atrn might also have a pheromone guided role during swarm formation and mating behaviour. Interpretation & conclusion: The relative expression profiling of Ac atrn gene in the larvae during nutritional and cold stress suggested its possible role in mediating chemical communication towards the food source and in thermal regulation of young larvae. Similarly, it might have crucial regulatory role in the stress management and survival of adult mosquitoes. The results revealed that Ac-atrn gene is a global regulator of many physiological processes in mosquitoes including stress response and mating behaviour and thus might be a potential target to design novel intervention strategy against mosquitoes. PMID- 30280707 TI - Comparative proteomics of salivary glands of Anopheles culicifacies mosquitoes using tandem mass tag (TMT) mass spectrometry. AB - Background & objectives: Salivary gland proteins play a pivotal role in blood feeding, epithelial interactions, and parasite transmission in mosquito vectors. Anopheles culicifacies is a complex of five sibling species, viz. A, B, C, D, and E, with diverse geographical distribution patterns. Among these, sibling species B has been identified as poor vector. Exploring the differentially expressed salivary proteins in An. culicifacies may potentially identify refractoriness factors during malaria parasite maturation and may help to elucidate the mechanism of refractoriness. Methods: A comparative proteomic analysis was carried out using tandem mass tag (TMT) technology combined with LC-MS/MS mass spectrometry and bioinformatics analysis, to identify the differentially expressed salivary gland proteins among An. culicifacies species A (susceptible) and An. culicifacies species B (refractory) mosquitoes. Results: A total of 82 proteins were found to be differentially expressed. Out of these, seven proteins including TRIO, translation initiation factor 5C, glutathione S-transferase, and 5' nucleotidase were up-regulated, and 75 proteins including calreticulin, elongation factors, fructose biphosphatase, isocitrate dehydrogenase, histone proteins and anti-platelet proteins, etc. were down-regulated in refractory species. Analysis of KEGG pathways showed that the up-regulated proteins were related to fatty acid metabolism and RNA transport pathways. Interpretation & conclusion: This comparative proteomic analysis of susceptible and refractory An. culicifacies salivary gland proteins identifies the plausible role of the differential proteome in immune responses, digestion, energy, and carbon metabolic pathways. This information may serve as a basis for future work concerning the possible role of these proteins in refractoriness dependent metabolic function of mosquitoes. PMID- 30280708 TI - Potent antileishmanial activity of chitosan against Iranian strain of Leishmania major (MRHO/IR/75/ER): In vitro and in vivo assay. AB - Background & objectives: Leishmaniasis is one of the major neglected zoonotic parasitic diseases whose treatment and control is very complex. Pentavalent antimonials remain the primary drugs against different forms of leishmaniasis, however, resistance to antimony and its toxic effects has necessitated the development of alternative medications such as use of medicinal plants and natural compounds. The aim of the current study was to assess the in vitro and in vivo activities of chitosan as a natural resource against Leishmania major. Methods: Low molecular weight chitosan, with 95% degree of deacetylation was melted in normal saline to a final concentration of 50, 100, 200 and 400 MUg/ml. Then, the promastigotes of L. major (Iranian strain) were added to the wells of 96-well plate and 20 MUl of each concentration was added to the RPMI 1640 medium. Live and dead promastigotes were counted after adding 0.1% eosin stain. The efficacy of the chitosan was also examined in BALB/c mice infected with Iranian strain of L. major. All in vitro experiments were performed in triplicate and the results of in vitro and in vivo tests were compared to the acetic acid and NaOH as negative control and glucantime as positive control. Results: The low molecular weight chitosan was completely effective at concentrations of 100, 200 and 400 MUg/ml on promastigotes of L. major after 180 min of application. Moreover, in the in vivo study, the mean size of dermal lesions significantly decreased in the groups treated with the chitosan compared to the control group. Interpretation & conclusion: According to the results of the study, it can be concluded that chitosan is a potent active compound against L. major and could be evaluated as a new antileishmanial drug in the future. PMID- 30280709 TI - Schistosoma mansoni infection in human and nonhuman primates in selected areas of Oromia Regional State, Ethiopia. AB - Background & objectives: The transmission of schistosomiasis, caused by trematodes of the genus Schistosoma, relies on freshwater snails that act as an intermediate host while human and other mammalian act as the definitive hosts. Many non-human primates (NHPs) such as Chlorocebus aethiops (vervet) and Papio anubis (baboon) are reported to be infected with Schistosoma mansoni in Ethiopia, but the role they play in parasite maintenance and transmission is still not clear. The objective of this study was, therefore, to determine the prevalence of S. mansoni infection in human and NHPs living in close proximities to villages in selected endemic areas of Ethiopia. Methods: In this cross-sectional study, stool specimens were collected from 911 humans, and fresh faecal droppings from 106 NHPs from Bochesa (Ziway), Bishan Gari (Kime) and Finchaa (Camp 7) endemic localities in Oromia Regional State, and examined for S. mansoni and other helminth infections using Kato-Katz method for human participants and direct microscopic examination for NHPs. Results: The prevalence of helminthiasis among the human study population was 42.4% (386/911), and for soil-transmitted helminth infections (A. lumbricoides, hookworms, and T. trichiura) it was 13.4% (122/911). In humans S. mansoni was the predominant parasite, 23.1% (210/911) followed by A. lumbricoides, 8.7% (79/911); hookworms, 5.8% (53/911); T. trichiura, 4.8% (44/911); Taenia species, 2.2% (20/911); E. vermicularis, 2.1% (19/911); and H. nana, 3.2% (29/911). NHPs were found positive for Trichuris species and Strongyloides species besides S. mansoni. Interpretation & conclusion: NHPs might play a significant role in local transmission and maintenance of S. mansoni infection even in the absence of human hosts. This calls for supplementation of chemotherapy for schistosomiasis along with measures such as snail control to interrupt transmission of the disease from humans to NHPs, and vice-versa. PMID- 30280710 TI - Small-scale (Phase II) evaluation of the efficacy and residual activity of SumiShield(r) 50 WG (clothianidin 50%, w/w) for indoor residual spraying in comparison to deltamethrin, bendiocarb and pirimiphos-methyl for malaria vector control in Karnataka state, India. AB - Background & objectives: There is an urgent need of introducing new insecticide molecules with novel modes of action to counter the ever growing insecticide resistance in mosquito vectors. In the present study, a new insecticide molecule, SumiShield 50 WG (clothianidin 50%, w/w) was investigated for its efficacy as an indoor residual spray along with its residual action in comparison to deltamethrin, pirimiphos-methyl and bendiocarb. Methods: The study area included three villages in Almatti Dam catchment area in Bagalkot district, Karnataka, India. Spraying was done using Hudson sprayers with the following dosages Clothianidin, 300 mg AI/m2; deltamethrin, 25 mg AI/m2; bendiocarb, 400 mg AI/m2; and pirimiphos-methyl, 1 g AI/m2. Cone bioassays were conducted on cement and mud plastered surfaces at fortnightly intervals to assess the bioefficacy and residual activity. Mosquito densities in the sprayed houses were recorded at regular intervals for assessment of the insecticidal efficacy. Filter paper samples collected from the sprayed houses were analyzed for insecticide content sprayed on different wall surfaces at the Walloon Agricultural Research Institute, Gembloux, Belgium. Results: Chemical content analysis of filter paper samples revealed that the applied to target ratios were in the acceptable range (1 + 0.5) for all the treatment types. Duration of persistence of effectiveness of bendiocarb (>=80% mortality in cone bioassays) was 19 to 21 wk on cement plastered surfaces and 15 to 19 wk on mud plastered surfaces. Duration of persistence of effectiveness of deltamethrin was 17 to 21 wk on both mud and cement plastered surfaces and that of pirimiphos-methyl was 15 to 19 wk. For SumiShield, it was 17 to 25 wk on both types of surfaces, indicating slow action of SumiShield. The densities of Anopheles culicifacies were lower in bendiocarb sprayed houses throughout the observation period, followed by pirimiphos methyl, deltamethrin and clothianidin sprayed houses. In case of other mosquitoes also, similar trend was observed. Interpretation & conclusion: Considering the persistence of effectiveness of SumiShield on sprayed surfaces, effectiveness in reducing the density of mosquitoes, operational feasibility, safety and community acceptance, the formulation of clothianidin is a better option for IRS for the control of insecticide-resistant mosquito vectors. PMID- 30280711 TI - Coinfections as an aetiology of acute undifferentiated febrile illness among adult patients in the sub-Himalayan region of north India. AB - Background & objectives: In India, certain geographic regions witness simultaneous outbreaks of two or more diseases like scrub typhus, dengue fever, malaria, leptospirosis and chikungunya during monsoon and post-monsoon period, sharing common indication of acute febrile illness. The objective of the present study was to assess the prevalence of coinfections among patients with acute undifferentiated fevers (AUF) admitted in a tertiary care hospital in the northern hilly state of Himachal Pradesh, India. Methods: This was a hospital based open cohort study conducted over a period of two months (September and October) in 2016. All the patients above the age of 18 yr admitted in medical wards and fulfilling the definition of AUF were included. The patients diagnosed with dual infections were the subjects of the study. Standard guidelines were used for case definitions of scrub typhus, dengue, chikungunya, malaria and leptospirosis. Results: Dual infections were noted in 16 patients admitted with AUF. The most common coinfection was scrub typhus and dengue, reported in 10 patients. Scrub typhus and leptospirosis coinfection was observed in three patients. Dengue and chikungunya was observed in one patient. Scrub typhus, dengue and vivax malaria was detected in one patient. Scrub typhus and vivax malaria was detected in one patient. Out of the 10 cases positive for both scrub and dengue, four had no history of travel outside Himachal Pradesh. All three cases positive for both scrub and leptospirosis were indigenous without any history of travel outside Kangra, Himachal Pradesh. The outcome of all the patients was with full recovery. Interpretation & conclusion: The study established the presence of coinfections (mainly dengue fever and leptospirosis) as a cause of AUF in the study area, which is a nonendemic region. The role of easily available and widely performed serological tests in the aetiological diagnosis of AUF is significant. Studies are required to determine the normal titres in the local population before using the imported commercially available serological tests in the diagnosis of AUF. PMID- 30280712 TI - Chikungunya virus outbreak in Sint Maarten: Long-term arthralgia after a 15-month period. AB - Background & objectives: The first chikungunya (CHIK) epidemic in the Americas was reported in December 2013. Chikungunya virus (CHIKV) causes an acute febrile illness and is transmitted to humans by Aedes mosquitoes. Although earlier studies have described long-term clinical manifestations of CHIK patients infected with the East/Central/South African (ECSA) genotype, little is known about persistent manifestations in the Caribbean region, for which the Asian genotype is responsible. The objective of this study was to describe the presence of persisting clinical manifestations, specifically arthralgia, in CHIKV-infected patients on the Caribbean Island, Sint Maarten, 15 months after onset of the disease. Methods: This retrospective cohort study included confirmed CHIK patients that were recorded by the participating general practitioners (GPs) during the chikungunya outbreak in 2014 in Sint Maarten. Between March and July 2015, 15 months after the onset of disease, patients were interviewed via telephone about the presence, duration and impact of clinical CHIKV manifestations. Results: In total, 56 patients were interviewed (median age 47 yr), of which 30 (54%) were females. Out of the total interviewed patients, 52 (93%) reported arthralgia for the first three months after the disease onset, of which 23 (44%) patients reported to have persistent arthralgia, 15 months after the disease onset. Pain intensity of persistent arthralgia was perceived as mild in the majority of patients (n = 14; 60%), moderate in 7 (30%) patients and severe in 2 (9%) patients. During the acute phase of disease, most patients had to miss school or work (n = 39; 72%) due to clinical CHIKV manifestations and reported a negative impact on daily activities (n = 36; 57%). Interpretation & conclusion: Results suggested that persisting arthralgia is a frequent complication in CHIK patients included in the study. Future research on strain specific clinical long-term manifestations and on their impact on daily life of patients, in the form of a comparative study between patients and controls, is recommended. PMID- 30280713 TI - Serological evidence of spotted fever group rickettsiosis in and around Puducherry, south India-A three years study. AB - Background & objectives: Rickettsial diseases are important re-emerging infections that mostly go unnoticed or are misdiagnosed. Though few case reports of Indian tick typhus have been reported in Indian literature in the past 10 yr, prevalence surveys are few and far between. The objective of this research was to study the seroprevalence of spotted fever (SF) group rickettsiosis and its coinfection with scrub typhus (ST) in Puducherry region of south India, as these two diseases may show similar clinical presentations. Methods: During 2012-2015, paired sera of 320 febrile patients were examined for Rickettsia conorii IgM/IgG by ELISA and OX19 and OX2 agglutinins by Weil-Felix test. Additionally, patients were screened for ST IgM ELISA. Statistical analysis was performed for clinical and laboratory parameters in children and adults using Fisher's exact test and chi-square test with Yates correction. Results: Out of 320 patients, 142 (44.38%) had R. conorii IgM and/or IgG antibodies. Only IgM was present in 72 (22.5%) patients, while 36 patients were positive for IgG only and 34 were positive for both IgG and IgM. A total of 68 patients (21.25%) showed only OX19 and/or OX2 antibodies (titres >= 1 : 80). SF and ST coinfection was observed in 47 cases (14.69%). Interpretation & conclusion: Seroprevalence of SF in Puducherry was found to be quite high (44.38%). ST and SF coinfection was observed in 34.50% of the SG IgG positive patients, however, this require further evaluation by PCR to rule out cross-reaction or false positivity. At present ELISA seems to be an affordable alternative to highly subjective and technically demanding immunofluorescence assay (IFA) for serodiagnosis of SF. PMID- 30280714 TI - Molecular detection of Dirofilaria immitis in dogs and mosquitoes in Tabasco, Mexico. AB - Background & objectives: Dirofilaria immitis is a filarial nematode that causes heartworm disease in domestic as well as wild canines and felines; and cutaneous or pulmonary infections in humans. The purpose of the study was to estimate the prevalence of D. immitis in domestic dogs in Tabasco, Mexico and to assay mosquitoes temporally and spatially associated with dogs for evidence of infection. Methods: Blood was collected from 1050 dogs in 1039 houses during a random household survey performed in 2016 and 2017. Genomic DNA was extracted and assayed by polymerase chain reaction (PCR) using pan-filarial primers and various species-specific primers. Dog owners were interviewed using a structured questionnaire designed to collect information on factors that may impact the occurrence of filarial infection. The association between canine dirofilariasis prevalence and factors likely to impact infection was determined by univariate logistic regression analysis, followed by multivariate binomial logistic regression analysis. Indoor and outdoor resting mosquitoes were collected from houses by manual aspiration. Mosquitoes were identified according to species, homogenized and tested by PCR for filarial nematodes. Results: A total of 84 (8%) dogs were positive for D. immitis DNA, while 3 (0.3%) dogs contained Acanthocheilonema reconditum DNA. Several factors were significantly associated with D. immitis infection. For example, dogs that lived <100 m from a large source of open standing water were significantly more likely (p = 0.002) to become infected with D. immitis than other dogs. Additionally, dogs with infrequent or no anthelmintic treatment were significantly more likely (p = 0.0) to become infected than dogs that were regularly treated. The entomologic investigation yielded 2618 female mosquitoes from 14 species. Four pools of Culex quinquefasciatus were positive for D. immitis DNA and the minimum infection rate, calculated as the number of positive pools per 1000 mosquitoes tested, was 2.9. Interpretation & conclusion: The study identified several factors positively associated with an increased risk of D. immitis infection in domestic dogs in Tabasco and provides evidence that Cx. quinquefasciatus is potentially an important vector in this region. This information can be used by local veterinarians and dog owners to reduce the burden of D. immitis on canine health.

AB - BACKGROUND This article reports a method to obtain vascular smooth muscle cells (SMCs) from the spiral modiolar artery (SMA) of guinea pigs and provides materials for related experimental studies. MATERIAL AND METHODS SMA was separated from the cochlea of guinea pigs, digested with trypsin (1.25 g/L) and allowed to adhere in a 35-mm culture dish. The morphology of the sample was investigated, and the sample was identified by immunofluorescence analysis, flow cytometry, Western blot, and RT-PCR. Cell viability was calculated using trypan blue and flow cytometry. Whole-cell patch clamp was used to record the membrane input resistance (Rinput), reciprocal membrane input conductance (Ginput), membrane input capacitance (Cinput), and resting membrane potential (RP) of the SMCs. RESULTS Microscopy results showed that the cells had typical peak-valley growth pattern. The cell growth curve was similar to an S curve, and flow cytometry results showed that the cell apoptosis rate was less than 10%. Moreover, flow cytometry, immunofluorescent staining, Western blot and RT-PCR detected the specific and intensely positive expression of cell type-specific markers alpha-SM-actin, SM22alpha, calponin and desmin. Furthermore, following properties of the P3 and P6 cells were obtained: Rinput, 2611+/-356 and 2477+/ 338 MOmega; Ginput, 0.454+/-0.071 and 0.273+/-0.037 ns; Cinput, 17.029+/-0.917 and 18.042+/-1.051 pF, and RP -20.602+/-1.503 and -22.192+/-1.905 mV. CONCLUSIONS Various highly purified SMCs were obtained from the SMA of guinea pigs. We provide an ideal experimental material for the study of the pathogenesis of diseases related to the circulation disturbances in the inner ear in vitro. The results can be used to evaluate the effects of drugs on vascular smooth muscle.

AB - OBJECTIVE: Nowadays, after licensure of the second generation new pneumococcal conjugate vaccines (PCV10/PCV13). The epidemiology of the pneumococcal disease must be re-evaluated. The present study described incidence, lethality and serotype distribution of invasive pneumococcal disease (IPD) in the general population of Tarragona's region (Spain) after licensure of these vaccines. METHODS: Retrospective study that included all cases of IPD (pneumococcus isolated in sterile sites) diagnosed among all-age individuals in the Spanish region of Tarragona (Tarragones, Alt Camp and Baix Penedes counties) from 01/01/2012 to 31/12/2015. Incidence and lethality rates were estimated by age strata and globally. Similarly, it was determined the prevalence of IPD cases caused by serotypes included in the distinct formulations of multivalent conjugate vaccines (pcv7), PCV10 and PCV13) or 23-valent polysaccharide vaccine (PPV23). RESULTS: A total of 171 IPD cases were observed, which means a global incidence (per 100,000 persons-year) of 10.82 (7.86 in <=14 years, 5.94 in 15-64 years and 36.46 in >=65 years; p<0.001). Overall lethality rate was 6.8% (none in children, 9,3% in people 15-64 years and 6.9% in people >=65 years). A serotype was identified in 132 (77.2%) of the 171 studied samples. Serotype-vaccine coverages (cases due to vaccine-type serotypes) were 14.4%, 26.5%, 42.4% and 78.8% for the PCV7, PCV10, PCV13 and PPV23, respectively (p<0.001). CONCLUSIONS: Incidence and lethality of IPD were intermediate-low in the region of Tarragona throughout 2012-2015. During this period, Serotype- vaccine coverage was almost double for the 23-valent than for the 13-valent vaccine. PMID- 30280721 TI - Evaluation of a novel cloud-based software platform for structured experiment design and linked data analytics. AB - Open data in science requires precise definition of experimental procedures used in data generation, but traditional practices for sharing protocols and data cannot provide the required data contextualization. Here, we explore implementation, in an academic research setting, of a novel cloud-based software system designed to address this challenge. The software supports systematic definition of experimental procedures as visual processes, acquisition and analysis of primary data, and linking of data and procedures in machine computable form. The software was tested on a set of quantitative microbial physiology experiments. Though time-intensive, definition of experimental procedures in the software enabled much more precise, unambiguous definitions of experiments than conventional protocols. Once defined, processes were easily reusable and composable into more complex experimental flows. Automatic coupling of process definitions to experimental data enables immediate identification of correlations between procedural details, intended and unintended experimental perturbations, and experimental outcomes. Software-based experiment descriptions could ultimately replace terse and ambiguous 'Materials and Methods' sections in scientific journals, thus promoting reproducibility and reusability of published studies. PMID- 30280722 TI - Ratiometric red-emission fluorescence detection of Al3+ in pure aqueous solution and live cells by a fluorescent peptidyl probe using aggregation-induced emission. AB - The development of a fluorescence method for the selective ratiometric detection of Al3+ ions in pure aqueous solutions and live cells is still a significant challenge. In the present study, we synthesized a new type of fluorescent probe using an Al3+-triggered self-assembly based on the dipeptide receptor and an aggregation-induced emission fluorophore. The fluorescent probe (1) bearing cyanostilbene with excitation by visible light detected Al3+ ions sensitively in pure aqueous buffered solution by ratiometric red-emission at 600 nm. 1 provided a highly selective ratiometric detection of Al3+ among 16 metal ions in aqueous solution. 1 exhibited sensitive ratiometric response to Al3+ in aqueous buffered solutions at pH ranging from 5 to 7.4. The detection limit (145 nM, R2 = 0.999) for Al3+ ions in pure aqueous solution was much lower than the maximum allowable level of Al3+ in drinking water demanded by the Environmental Protection Agency (EPA). The probe provided an efficient approach to detect low concentrations of Al3+ in ground water, tap water, and live cells by ratiometric red-emissions at 600 nm. The binding study using dynamic light scattering, NMR, IR, and TEM revealed that the complex between 1 and Al3+ self-assembled to form nanoparticles, resulting in the enhancement of the emission at 600 nm and a concomitant decrease in the emission at 535 nm. PMID- 30280723 TI - Human-level blood cell counting on lens-free shadow images exploiting deep neural networks. AB - In point-of-care testing, in-line holographic microscopes paved the way for realizing portable cell counting systems at marginal cost. To maximize their accuracy, it is critically important to reliably count the number of cells even in noisy blood images overcoming various problems due to out-of-focus blurry cells and background brightness variations. However, previous studies could detect cells only on clean images while they failed to accurately distinguish blurry cells from background noises. To address this problem, we present a human level blood cell counting system by synergistically integrating the methods of normalized cross-correlation (NCC) and a convolutional neural network (CNN). Our comprehensive performance evaluation demonstrates that the proposed system achieves the highest level of accuracy (96.7-98.4%) for any kinds of blood cells on a lens-free shadow image while others suffer from significant accuracy degradations (12.9-38.9%) when detecting blurry cells. Moreover, it outperforms others by up to 36.8% in accurately analyzing noisy blood images and is 24.0 40.8* faster, thus maximizing both accuracy and computational efficiency.

AB - Surface-enhanced Raman scattering (SERS) is one of the important techniques for sensing applications in biological analysis, disease diagnosis, environmental science, and food safety. Graphene provides an excellent nanoplatform for SERS sensing due to its two-dimensional flat structure, uniform electronic and photonic properties, excellent mechanical stability, atomic uniformity, and high biocompatibility. In this review, we summarize recent advances in the fabrication of various graphene-based nanoplatforms for SERS sensing. We present the strategies, such as self-assembly, in situ synthesis, one-pot synthesis, liquid phase reduction, and biomimetic synthesis, for the fabrication of graphene-based hybrid metallic and alloy nanoplatforms, and then demonstrate the potential applications of graphene-based nanoplatforms for the SERS sensing of ions, organic dyes, pesticides, bacteria, DNA, proteins, cells, and other chemicals in great detail. In addition, we also discuss the future development of this interesting research field and provide several perspectives. This work will be helpful for readers to understand the fabrication and sensing mechanisms of graphene-based SERS sensing nanoplatforms; meanwhile, it will promote the development of new materials and novel methods for high performance sensing and biosensing applications.

AB - Hierarchically porous UiO-66 (HP-UiO-66) with a particle size of ~5 nm was synthesized without the use of modulating reagents. The HP-UiO-66 material exhibits good thermal and structural stability, and shows excellent performance in uptaking large molecules and catalyzing the acetalization reaction of furfural. PMID- 30280726 TI - Edge-on adsorption of multi-chain functional alkanes stabilizes noncovalent monolayers on MoS2. AB - Modified long-chain alkanes are often used to functionalize graphene and MoS2 noncovalently, with the goal of controlling the substrate electronic structure or interactions with the environment. Alkyl chain adsorption enthalpy is lower on MoS2 than on graphite; the decreased molecule-substrate interaction strength suggests utility for monolayer structures that increase stability through other means. Previously, we have found that diyne phospholipid monolayers on HOPG are more stable toward solution processing than monolayers of single-chain amphiphiles. Here, we show that this is also true for assembly on MoS2, but that the additional stability appears to arise from edge-on adsorption, producing monolayers in which alkyl chains form two stacked layers on the substrate. PMID- 30280727 TI - Heavy pnictogen chalcohalides: the synthesis, structure and properties of these rediscovered semiconductors. AB - This review focuses on the synthesis, properties and selected applications of heavy pnictogen chalcohalides, i.e. compounds of the MQX stoichiometry, where M = As, Sb, and Bi; Q = O, S, Se, and Te; and X = F, Cl, Br and I. The first section focuses on their synthesis and crystal structures, and the second section discusses the electronic structure on the basis of quantum chemical modelling and selected experimental data. Finally, the third section discusses their electrical, photoelectrochemical and photocatalytic properties and applications. In contrast to perovskites, chalcopyrites and kesterites, chalcohalides have attracted relatively less attention, but their structure and properties are well suited for numerous applications. PMID- 30280728 TI - Multilayer sensing platform: gold nanoparticles/prussian blue decorated graphite paper for NADH and H2O2 detection. AB - In this study, an exfoliated graphite paper (EGP) was employed as a supported electrode for prussian blue (PB) and gold nanoparticles (AuNPs) modification to fabricate a novel electrochemical sensor. The scanning electron microscopy image showed the multilayer structure of the sensor with PB and AuNPs uniform coating. Due to the high surface area and good conductivity of the multilayer structure, as well as the conductivity of AuNPs, the prepared sensor exhibited an obvious improvement for sensitive detection of nicotinamide adenine dinucleotide (NADH) with a linear range of 5.0 * 10-7 mol L-1-1.0 * 10-3 mol L-1. Moreover, the modified PB film endowed the sensor with good electrocatalytic activity for hydrogen peroxide (H2O2) sensing. Under the optimal conditions, the linear range and limit of detection for H2O2 sensitive detection were 5.0 * 10-8 mol L-1-1.0 * 10-3 mol L-1 and 4.8 * 10-9 mol L-1, respectively. The sensor can also be used for detection in real samples with satisfactory results. The advantages of low cost, easy modification, multilayer structure, and good conductivity made the EGP an alternative candidate for supported electrode materials in the preparation and application of various electrochemical sensors.

AB - Inspired by MOFs themselves as unique matrices and electrocatalysts, we present a surprising discovery that rare PtNi@MIL-101 exhibits excellent synergistic catalysis for methylene blue.

AB - Silicon nanocomposites with surface coating have been promising candidates for high-performance anodes in Li-ion batteries. Here we report a simple yet effective way to synthesize Si@SiO2 nanocomposites with amorphous SiO2 coating through a fluoride ion-mediated continuous etching-redeposition process. The Si@SiO2 nanocomposite anode exhibits significantly improved lithium storage properties, with a reversible capacity of 1356 mA h g-1 at 2.1 A g-1 for 300 cycles. PMID- 30280731 TI - A novel electrochemical immunoassay for carcinoembryonic antigen based on glucose oxidase-encapsulated nanogold hollow spheres with a pH meter readout. AB - A portable electrochemical immunosensing protocol was designed for the sensitive detection of a disease-related tumor biomarker (carcinoembryonic antigen, CEA, used in this case) on a pH meter using glucose oxidase (GOx)-encapsulated gold hollow microspheres (AuHMs) for signal amplification. The assay was carried out on a monoclonal anti-CEA capture antibody-coated microplate with a sandwich-type reaction mode. The GOx-entrapped AuHM was first synthesized using the reverse micelle method and then used as the signal-generation tag for the labeling of polyclonal anti-CEA detection antibody. Accompanying the formation of the sandwiched immunocomplexes, the loaded GOx molecules in the microsphere could catalyze glucose into gluconic acid and hydrogen peroxide. The as-produced gluconic acid changed the microenvironment of the detection solution, thus resulting in the shift of the pH value, which could be quantitatively determined on a portable pH meter. The use of gold hollow microspheres was expected to enhance the loaded amount of GOx for signal amplification. Two labeling protocols including GOx-labeled secondary antibody and GOx-AuHM-labeled secondary antibody were investigated for CEA detection, and improved analytical features were acquired with GOx-AuHM labeling. With the GOx-AuHM labeling strategy, the pH meter-based immunosensing device exhibited a good analytical performance for CEA detection within the dynamic linear range of 0.1-100 ng mL-1 at a detection limit of 0.062 ng mL-1. The strong attachment of anti-CEA antibodies to GOx-AuHM brought a good repeatability and intermediate precision down to 10%. Importantly, no significant differences at the 0.05 significance level were encountered in the analysis of 12 human serum specimens between the developed immunoassay and the commercialized electrochemiluminescent method for CEA determination. PMID- 30280732 TI - Exonuclease III-assisted multiple cycle amplification for the sensitive detection of DNA with zero background signal. AB - Detection of low-abundant DNA is essential for disease diagnosis and treatment. DNA polymerase-based amplification is frequently used due to its excellent sensitivity, but it suffers from time-consuming and labour-intensive procedures, complex template/primer design, and inherent nonspecific amplification. Alternatively, Exonuclease III (Exo III)-assisted target recycling provides a new approach for DNA assay because of its simplicity and general applicability, but it suffers from high background signal due to the nonspecific Exo III digestion and poor sensitivity due to single cycle signal amplification. Herein, we demonstrate the development of Exo III-assisted multiple cycle amplification (exonuclease chain reaction) for the sensitive detection of DNA with zero background signal. The binding of single-stranded DNA binding protein (SSB) to the hairpin probes can protect them from nonspecific digestion by Exo III, resulting in near zero background signal. The presence of the target DNA initiates the Exo III-triggered multiple cycle amplification, enabling the achievement of high sensitivity with a detection limit of 3 fM and excellent selectivity with single base mismatch discrimination capability, holding great potential in disease diagnosis and biomedical research.

AB - Wheel-type heptanuclear heterometallic clusters of stoichiometry [Ni7 xMx(HL)6(MU3-OMe)4(MU3-OH)2]Cl2 (L = 1-(2-hydroxy-3-methoxybenzamido)-2 (benzylideneamino)ethane; M = Zn2+, Co2+, Mn2+; x = 1, 3) were synthesized, and their metal ion dependent ferromagnetic properties were investigated. It was demonstrated that the central position of each cluster was occupied by a Ni2+ ion while other metal ions (Zn2+, Co2+ or Mn2+) were accommodated in peripheral positions. The magnetic interactions, anisotropy and magnetization of the resultant clusters were all influenced by the combinations of metal ions present.

AB - Photocatalysis is a promising technology which can be applied in the fields of energy and environment. However, low charge separation efficiency has limited its commercial applications. In this work, we report a route to a controllable synthesized visible-light-driven heterostructure photocatalyst Mo2C@C/2D g-C3N4. The interfacial conductivity was improved by introducing Mo2C@C, which promoted the transportation of photogenerated carriers and suppressed their recombination. The optimal composite achieved a hydrogen (H2) generation rate of 2269.47 MUmol g 1 h-1, and an external quantum efficiency (EQE) achieved 9.07% at lambda = 405 nm. Thus, the great co-catalytic activity of Mo2C@C was unambiguously demonstrated. PMID- 30280735 TI - Protein-protein interactions in trans-AT polyketide synthases. AB - Covering: up to 2018 The construction of polyketide natural products by type I modular polyketide synthases (PKSs) requires the coordinated action of several protein subunits to ensure biosynthetic fidelity. This is particularly the case for trans-AT PKSs, which in contrast to most cis-AT PKSs, contain split modules and employ several trans-acting catalytic domains. This article summarises recent advances in understanding the protein-protein interactions underpinning subunit assembly and intra-subunit communication in such systems and highlights potential avenues and approaches for future research. PMID- 30280736 TI - A new quinoline based luminescent Zr(iv) metal-organic framework for the ultrasensitive recognition of 4-nitrophenol and Fe(iii) ions. AB - A Zr(iv) based luminescent metal-organic framework (MOF; 1) was synthesized by a solvothermal method using a mixture of ZrCl4, quinoline-2,6-dicarboxylic acid (H2QDA) ligand and trifluoroacetic acid (modulator) having a 1 : 1 : 10 molar ratio in N,N-dimethylformamide (DMF). For activation, the methanol-exchanged sample was heated under high vacuum at 120 degrees C for 1 day. Different techniques like X-ray powder diffraction (XRPD), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) spectroscopy and energy dispersive X ray (EDX) analysis were applied to fully characterize 1. The activated form of 1 (called 1') has the formula [Zr6O6(OH)2(CF3COO)2(C11H5NO4)4(H2O)4]. It exhibited quick response and great selectivity for the fluorimetric sensing of 4 nitrophenol (4-NP) in acetonitrile and Fe3+ ions in water. The probe maintained its high selectivity for 4-NP and Fe3+ ions even in the presence of potentially intrusive nitroaromatics and metal ions, respectively. The detection limits for 4 NP and Fe3+ were found to be 1.40 ppt and 0.71 ppb, respectively. These values are the lowest among the existing MOF probes for Fe3+ and 4-NP. The electron and energy transfer processes along with the electrostatic interactions of 4-NP with the MOF can be the possible reasons for the selectivity for 4-NP. The fluorescence resonance energy transfer (FRET) process can be the major reason behind the quenching mechanism for Fe3+ ions. The recyclability test indicates that 1' is a promising probe for the long-term detection of 4-NP and Fe3+ ions. PMID- 30280741 TI - Three microporous metal-organic frameworks assembled from dodecanuclear {NiLn} subunits: synthesis, structure, gas adsorption and magnetism. AB - Three isostructural heterometallic metal-organic frameworks (MOFs) {[Ln2Ni(OAc)5(HL)(L)].solvent molecules}n (H2L = 2-hydroxyimino-N-[1-(2 pyrazinyl)ethylidene]-propanohydrazone, Ln = Dy for 1, Tb for 2 and Gd for 3) were solvothermally synthesized by varying rare-earth metal ions with different electron configurations. Their crystal structures, gas adsorption and magnetic behaviors were fully investigated. The three isomorphous MOFs exhibit three dimensional microporous frameworks with two different orientated dodecane metallic {NiIILnIII(HL)}6 metallomacrocycles alternately connected by {LnIII(L)} connectors, in which an empty one-dimensional channel decorated by the basic hydrazone interior is generated. Due to their LnIII-independent microporous nature, the activated sample of 1 as a representative example has a significant CO2 uptake up to 42.2 cm3 g-1 and an unusually high CO2/N2 and CO2/CH4 adsorption selectivity of up to 98.8 and 16.8 at 298 K and 100 kPa. Magnetically, apparent antiferromagnetic interactions for both 1 and 2 as well as ferromagnetic coupling for 3 are respectively observed at low temperature resulting from the competition of magnetic anisotropy and intermetallic ferromagnetic superexchange. Additionally, 1 with highly anisotropic DyIII spin shows slow magnetization relaxation under zero dc field, whereas 3 possessing isotropic GdIII ions displays a significant cryogenic magnetocaloric effect with a maximum entropy change of 26.6 J kg-1 K-1 at 3.0 K and 70 kOe. These interesting results can provide valuable information on gas separation-based multifunctional 3d-4f MOF materials. PMID- 30280742 TI - The suppression of CMR in Nd(Mn1-xCox)AsO0.95F0.05. AB - The colossal magnetoresistance (CMR) observed in the oxypnictide NdMnAsO1-xFx has been further investigated. The magnetotransport is dominated by magnetopolarons. Magnetoresistance measurements of the series Nd(Mn1-xCox)AsO0.95F0.05 show that doping with cobalt on the manganese site pins the magnetopolarons and suppresses the CMR, which is completely destroyed by x = 0.047. The chemical doping results in non-stoichiometric samples, with both As and O vacancies. The relationship between the non-stoichiometry, magnetic order, electron doping and CMR is explored. The Nd antiferromagnetic transition and simultaneous reorientation of the Mn spins into the basal plane at 23 K (TSR) is not effected by Co doping. However, there is a significant decrease in TN(Mn) as the antiferromagnetic transition is suppressed from 360 K to 300 K as x increases from 0-0.047. The manganese moment at 10 K is also reduced from 3.86(2)MUB to 3.21(2)MUB over the same doping range. This reduction in the in-plane Mn moment decreases the electron-electron correlations below TSR and acts to further diminish the magnetoresistance.

AB - The main commercial infrared nonlinear optical (IR NLO) crystals, typically, AgGaS2, have some inherent disadvantages, for example, low laser damage threshold (LDT) or relatively poor stability, which limit their wide application. Here, we discover two new IR optical perovskites based on 1,4-diazabicyclo[2,2,2]octane, namely, (H2dabco)(PbCl3)2 (1) and (H2dabco)(H2PbBr6).H2O (2). 1 and 2 crystallize in the noncentrosymmetric space groups P43212 and P63mc, respectively, displaying a broad transparent range with high transmission. Particularly, compound 2 exhibits a moderate SHG response of 1.8 times that of KH2PO4 (KDP) at 1064 nm with a high laser-induced damage threshold of 328.8 MW cm-2, indicating that it is a new promising NLO material. PMID- 30280744 TI - Pyrite FeS2/C nanoparticles as an efficient bi-functional catalyst for overall water splitting. AB - Exploration and fabrication of low-cost but highly active electrocatalysts, alternatives to noble metals, have remained a challenge for overall water splitting reaction. To date, few studies have reported that the Earth-abundant pyrite FeS2 is catalytically active for hydrogen evolution reaction, while there is no study on the oxygen evolution reaction and overall water splitting reaction using pyrite FeS2 as an electrocatalyst. Here, we offer a facile hydrothermal approach for the synthesis of FeS2 nanoparticles by the reduction of FeCl3.6H2O with C5H10NS2Na.3H2O. The FeS2/C nanoparticles on Ni foam (NF) deliver 10 mA cm-2 at an overpotential of 240 mV towards the oxygen evolution reaction, which is lower than that of IrO2. It requires 202 mV to drive the hydrogen evolution reaction to reach 10 mA cm-2, while long-term durability and faster charge transfer kinetics confirm the good hydrogen evolution reaction performance on FeS2/C/Ni foam. Moreover, the pyrite FeS2/C/nanoparticles on Ni foam are assembled as an anode and cathode in a two-electrode alkaline electrolyzer and show good overall water splitting efficiency with 1.72 V at 10 mA cm-2.

AB - Electrospray ionisation mass spectrometry (ESI-MS) was used to monitor the reaction of AgBF4, bis(diphenylphosphino)amine (dppa = (Ph2P)2NH = LPh) and NaBH4 in acetonitrile and thereby direct the synthesis of the silver nanocluster [Ag3(MU3-H)(MU3-BH4)LPh3](BF4), 3b.BF4, formed via reaction of AgBF4, bis(diphenylphosphino)amine (dppa = (Ph2P)2NH = LPh) and NaBH4 in acetonitrile. The X-ray structure of 3b.BF4 highlights that the cation adopts a planar trinuclear Ag3 geometry surrounded by three dppa ligands and coordinated on the bottom face by a MU3-hydride and on the top face by a MU3-BH4. The solution phase structure of 3b.BF4 was characterised by multinuclear NMR and DOSY NMR, which showed that the borohydride anion remains bound in the [Ag3(MU3-H)(MU3-BH4)LPh3]+ cluster cation in solution. ESI-MS and in situ1H and HSQC NMR spectroscopy reveals that 3b.BF4 reacts with CS2 in solution at the BH4 site to yield [Ag3(H)(S2CH)LPh3]+, 4b, which has to date eluded structural characterisation via X-ray crystallography due to lack of formation of suitable crystals. The gas phase ion chemistry of [Ag3(H)(S2CH)LPh3]+ was examined under multistage mass spectrometry conditions using collision-induced dissociation (CID) and compared to that of the previously examined copper analogue, [Cu3(H)(S2CH)LPh3]+. While both cluster cations fragment via ligand loss, the CID spectra of the resultant [M3(H)(S2CH)LPh2]+ are different. Unlike [Cu3(H)(S2CH)LPh2]+, which solely undergoes loss of thioformaldehyde to give [Cu3(S)LPh2]+, [Ag3(H)(S2CH)LPh2]+ gives a richer CID spectrum with fragmentation channels that include ligand loss, CH2S loss and reductive elimination of dithioformic acid. DFT calculations exploring rearrangement and fragmentation of the model systems [M3(H)(S2CH)LMe2]+ ((Me2P)2NH = dmpa = LMe) were used to suggest plausible mechanisms and examine the energetics of the three competing channels: ligand loss, CH2S loss and reductive elimination of dithioformic acid. PMID- 30280746 TI - The synergistic effect of layered double hydroxides with other flame retardant additives for polymer nanocomposites: a critical review. AB - Layered double hydroxides (LDHs) are a new type of inorganic flame retardant additive for polymer nanocomposites. Although their unique structural properties and tunable chemical compositions make them highly promising, it has been noticed that on their own, LDHs can hardly fulfill all the requirements for commercial applications. In recent years, the application of LDHs together with other synergistic additives has been proposed as a new route for obtaining highly efficient flame retardant polymer nanocomposites. It is believed that the synergistic additives can overcome the shortcomings of LDHs. As great progress has been made in this field so far, we believe that a timely review is warranted. Thus, in this contribution, the synergistic effect of LDHs with other flame retardant additives including (1) phosphorus-containing compounds, (2) graphene and carbon compounds, (3) intumescent flame retardants, (4) magnesium hydroxide, (5) borate-containing compounds, and (6) some other flame retardant compounds will be critically reviewed. For each type of additive, the synergistic mechanism with LDHs, and their performance on both flame retardancy and thermal stability will be discussed. We believe that this work will inspire and guide researchers from a wide range of backgrounds and help to pave the way for major breakthroughs in both fundamental studies and industrial applications in this field. PMID- 30280748 TI - Leveraging plant exine capsules as pH-responsive delivery vehicles for hydrophobic nutraceutical encapsulation. AB - Plant exine capsules are natural microscale capsules that are highly physically robust and chemically resilient. They are extracted from pollen grains and plant spores, and can be used as renewable and safe microcapsules for encapsulation applications. Herein, we report the successful evacuation of natural sunflower pollen grains (SPGs) and Lycopodiastrum casuarinoides spore exine capsules (SECs) and investigated the effects of different loading methods on the encapsulation and release of nobiletin, a model hydrophobic nutraceutical. The compositional and morphological characterizations of SPGs and SECs obtained by the developed extraction protocol confirmed that the inside contents had been removed and hollow pollen cavities were obtained successfully. In addition, coumarin-6, a hydrophobic fluorescent probe, was encapsulated into SPGs and SECs, which proved the possibility of using them to encapsulate hydrophobic nutraceuticals. Furthermore, controlled release in simulated digestive fluids (SDF) was achieved by coating calcium alginate onto the outside of the SPGs and SECs. Looking forward, this may provide an effective and potential delivery model to protect loads from degradation in the stomach and achieve pH-responsive delivery of hydrophobic nutraceuticals after oral administration.

AB - This work focuses on the application of dicobalt octacarbonyl (Co2(CO)8) as a metal precursor in the chemistry of formally low-valent cobalt with redox-active bis(imino)pyridine [NNN] ligands. The reactions of both mononucleating mesityl substituted bis(aldimino)pyridine (L1) and dinucleating macrocyclic xanthene bridged di(bis(aldimino)pyridine) (L2) with Co2(CO)8 were investigated. Independent of the metal-to-ligand ratio (1 : 1 or 1 : 2 ligand to Co2(CO)8), the reaction of the dinucleating ligand L2 with Co2(CO)8 produces a tetranuclear complex [Co4(L2)(CO)10] featuring two discrete [Co2[NNN](CO)5] units. In contrast, a related mononucleating bis(aldimino)pyridine ligand, L1, produces different species at different ligand to Co2(CO)8 ratios, including dinuclear [Co2(CO)5(L1)] and zwitterionic [Co(L1)2][Co(CO)4]. Interestingly, [Co4(L2)(CO)10] features metal-metal bonds, and no bridging carbonyls, whereas [Co2(CO)5(L1)] contains cobalt centers bridged by one or two carbonyl ligands. In either case, treatment with excess acetonitrile leads to disproportionation to the zwitterionic [Co[NNN](NCMe)2][Co(CO)4] units. The electronic structures of the complexes described above were studied with density functional theory. All the obtained bis(imino)pyridine complexes serve as catalysts for cyclotrimerization of methyl propiolate, albeit their reactivity is inferior compared with Co2(CO)8.

AB - Perovskite-structured cesium lead bromide (CsPbBr3) halide provides new opportunities for promoting the commercialization of perovskite solar cells (PSC) due to its high carrier mobility and light absorption coefficient as well as remarkable environmental stability at high humidity and high temperatures. Herein, all-carbon electrodes from multi-walled carbon nanotubes (MWCNT) and carbon black (CB) were prepared for all-inorganic CsPbBr3 PSCs with the configuration of FTO/c-TiO2/m-TiO2/CsPbBr3/carbon. The as-prepared electrodes were free of hole-transporting layers and precious metals. The work function and electrical conductivity of the carbon electrode were tuned by changing the MWCNT/CB ratio to reduce charge recombination at the perovskite/carbon interface. The optimal all-inorganic PSC achieves a maximum power conversion efficiency of 7.62% using the MWCNT (75 wt%)/CB (25 wt%) electrode in comparison with 6.24% for the pure MWCNT-based device. Upon persistent attack by 80% RH in air atmosphere, the solar cell retains 95% of its initial efficiency over 1100 h.

AB - This study investigated the effect of microencapsulated garlic and/or tomato on endothelial dysfunction induced by the PhenFlex test (PFT) in healthy male smokers. In a randomized, double-blind, placebo-controlled crossover trial, 41 healthy male smokers were randomly assigned to one of four groups to receive the test groups (in microencapsulated garlic powder, tomato extract and a mixture thereof) or the placebo group. Proteomic biomarkers related to endothelial integrity were measured in plasma. Microencapsulated garlic, tomato extract and the mixture affected endothelial integrity biomarkers differently. Garlic consumption increased prothrombin time and decreased SAA and IL-12. Tomato extract intake increased activated partial thrombin time and decreased d-dimer, SAA, sVCAM-1, IL-13 and MCP-3 levels. Consumption of the mixture increased sE selectin and lowered D-dimer, SAA, IL-13 and IL-10 responses after PFT challenge for 6 h. The different responses became clearer under high compliance in the dietary restriction groups. This single-intake clinical trial addressed the different responses of biomarkers related to endothelial integrity.

AB - OBJECTIVE: In recent years metagenomic analysis has become more accessible for the characterization of biological specimens. There has been an important increase of studies using this technique for subgingival human samples. To date, there are no updated systematic reviews on the relationship between oral microbiota and periodontal disease. The aim of the present systematic review was to update data about studies concerning the influences of changes in oral microbiota composition on the periodontal status in human subjects. MATERIALS AND METHODS: An electronic search was conducted in four databases (MEDLINE, Scopus, CENTRAL and Web of Science) for articles published in English from January 2014 to April 2018. In vitro or animal studies, case reports, case series, retrospective studies, review articles, abstracts and discussions were excluded. Also, studies that evaluated less than 5 microbial species, only viruses or already known periodontal pathogens were excluded. Two independent researches selected the studies and extracted the data. The quality of evidence was assessed as high, moderate or low for each microorganism. RESULTS: Eight studies and three additional publications recovered from the bibliography search of the selected articles were included in the review. The Bacteria domain was the main detected among the others and it included 53 species. The review confirmed the presence of recognized periodontal pathogens such as the members of the red complex but also identified, with high weight of evidence, the presence of new pathogens. CONCLUSIONS: The results of this systematic review support high evidence for the association of 3 new species/genera with the etiology of periodontitis. Future investigations on the actual role of these new pathogens in the onset and progression of the disease are needed. PMID- 30280757 TI - p38-MAPK pathway is activated in retinopathy of microvascular disease of STZ induced diabetic rat model. AB - OBJECTIVE: To investigate the role of corticotropin releasing hormone (CRH) in diabetic retinopathy of microvascular disease and the potential mechanism. MATERIALS AND METHODS: The diabetic rat model was constructed by a single intraperitoneal injection of streptozotocin (STZ). The expression of CRH in the retina of diabetic rats and wild-type rats was detected by Real-Time Polymerase Chain Reaction (RT-PCR). CRH shRNA or Scr shRNA adenovirus was injected into the eyes of diabetic rats and wild-type rats, respectively. The effect of down regulated CRH on visual electrophysiology in rats was evaluated. Protein expressions of vascular endothelial growth factor (VEGF) and inflammatory factors that were related to the microvascular lesion after CRH downregulation were detected by Western blot. Furthermore, p38 expression was detected by Western blot to explore whether mitogen-activated protein kinase (MAPK) signaling pathway was involved in the function of retinal endothelial cells regulated by CRH. RESULTS: The expression of CRH was significantly up-regulated in the retina of diabetic rats. RT-PCR results showed that the mRNA level of CRH in the retina of diabetic rats injected with CRH shRNA was decreased. However, no significant change in CRH level was observed in rats injected with Scr shRNA adenovirus. The down-regulated CRH could improve the diabetes-induced visual impairment and retinal inflammatory response. Moreover, the down-regulated CRH led to a decreased phosphorylation level of p38. CONCLUSIONS: CRH improves the diabetic retinopathy of microvascular disease via the p38-MAPK pathway, which is expected to be a new target for the treatment of diabetic microangiopathy. PMID- 30280758 TI - Hsa-miR-203 inhibits fracture healing via targeting PBOV1. AB - OBJECTIVE: To explore the role of hsa-miR-203 in fracture healing and its underlying mechanism. PATIENTS AND METHODS: Expression levels of hsa-miR-203 and PBOV1 in patients with hand fractures and intra-articular fractures after treatment were detected by quantitative Real-Time-Polymerase Chain Reaction (qRT PCR). Viability and apoptosis of osteoblast cell line hFOB1.19 after hsa-miR-203 overexpression or knockdown were detected by cell counting kit-8 (CCK-8) assay and flow cytometry, respectively. The target gene of hsa-miR-203 was predicted by bioinformatics and verified by dual-luciferase reporter gene assay. Rescue experiments were conducted to further verify whether hsa-miR-203 could participate in fracture healing via PBOV1. RESULTS: No significant hsa-miR-203 expression was found in patients with hand fractures and intra-articular fractures after treatment for 7 days, which was remarkably upregulated on the 14th day. PBOV1 expression was gradually downregulated as treatment time prolongation. Overexpression of hsa-miR-203 decreased cell viability, but induced apoptosis of hFOB1.19 cells. Bioinformatics predicted that PBOV1 might be the target gene of hsa-miR-203, which was further verified by dual-luciferase reporter gene assay. The effect of hsa-miR-203 on viability and apoptosis of hFOB1.19 cells was reversed after the PBOV1 knockdown. CONCLUSIONS: Hsa-miR-203 inhibits fracture healing by regulating osteoblast viability and apoptosis via targeting PBOV1. PMID- 30280759 TI - MiR-203 is essential for the shift from osteogenic differentiation to adipogenic differentiation of mesenchymal stem cells in postmenopausal osteoporosis. AB - OBJECTIVE: The purpose of this study was to investigate how miR-203 promotes osteogenic differentiation of bone marrow mesenchymal cells (BMSCs) by regulating its target gene DKK1, thereby inhibiting the occurrence of osteoporosis. PATIENTS AND METHODS: A total of 60 cases with postmenopausal osteoporosis and 40 cases of normal individuals were recruited. The expression of miR-203 in serum of all cases was detected by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). The capacity of osteogenesis and adipogenic differentiation of MSCs was determined by alizarin red staining and oil red staining, respectively. Transfection of miR-203 mimics and miR-203 inhibitor were mediated by Liposomes, and then the MSCs were induced osteogenic and adipogenic differentiation. MiR-203 mimic was co-transfected with wild-type or mutant DKK1 for luciferase reporter gene detection. In the osteoporosis model of rats, the tibia was taken for micro-CT examination of bone mineral density (BMD) and bone volume/structural parameters (BV/TV), while the femur was taken for the measurement of absorption parameters (Ob.S)./BS) and the number of osteoclasts per circumference of bone (N.Oc/B.Pm). RESULTS: The expression level of miR-203 was significantly lower in patients with postmenopausal osteoporosis than that in normal individuals. The osteogenic capacity of BMSCs in these patients was reduced, while their adipogenic capacity was enhanced. MiR-203 promoted the expression of osteogenic genes and inhibited that of adipogenic genes. Knockdown of miR-203 decreased the level of osteogenic related genes but increased that of adipogenic related genes, while overexpression of miR-203 led to the opposite results. Furthermore, miR-203 inhibited the protein expression of DKK1. In addition, bone density and bone volume/structural parameters were lower in ovariectomized rats than those in normal rats. Meanwhile, bone resorption parameters and the number of osteoclasts per bone circumference in ovariectomized rats were higher than those in normal rats. CONCLUSIONS: MiR-203 can promote osteogenic differentiation of mesenchymal stem cells by downregulating the gene expression of DKK1. PMID- 30280760 TI - CRNDE impacts the proliferation of osteoclast by estrogen deficiency in postmenopausal osteoporosis. AB - OBJECTIVE: Bone loss is the main reason for postmenopausal osteoporosis, caused by estrogen deficiency. ERT (estrogen replacement therapy) has been demonstrated to protect bone loss efficiently. LncRNA (long non-coding RNA) has been proved to be important in different disease progression. We aimed at analyzing whether the lncRNAs influence the activity of osteoclasts and the progression of this disease. PATIENTS AND METHODS: RT-PCR (reverse transcriptase-polymerase chain reaction) was used to detect the expression of lncRNA CRNDE in OH (osteoclast from healthy people) and OP (osteoclast from patients with postmenopausal osteoporosis). MTT (methylthiazolyl tetrazolium) assay was used to detect the viability of the cells. The cell cycle and apoptosis rate in OH and OP were measured by the flow cytometry analysis. Western blot was used to analyze the possible related mechanism that CRNDE regulated the cells proliferation in postmenopausal osteoporosis. RESULTS: We found that the CRNDE was highly expressed in the osteoclast from patients with OP, compared with OH. We also found that overexpressing CRNDE increased the viability in OH whilst reducing CRNDE in OP decreased the viability. The cell cycle was arrested in G0/G1 phase and the apoptosis rate was improved in OP after transfection with siRNA. Moreover, CRNDE could impact the proliferation of osteoclasts by PI3K/Akt signaling pathway and estrogen could inhibit this proliferation. CONCLUSIONS: We found that lncRNA CRNDE was closely related to the postmenopausal osteoporosis with estrogen deficiency. CRNDE may be involved in the development and progression of postmenopausal osteoporosis in the absence of estrogen and become a potential target for treating. PMID- 30280761 TI - The impact of collagen sponge composite bone marrow mesenchymal stem cells (BMSCs) in inducing interbody fusion. AB - OBJECTIVE: To assess the effectiveness of bone mesenchymal stem cells (BMSCs) in the induction of interbody fusion. PATIENTS AND METHODS: The 3rd generation BMSCs were seeded on collagen sponge scaffold and cultured in osteoblast induction medium for 3 weeks to prepare cell-scaffold complex. Thirty patients were randomly divided into three groups to establish the L4/L5 interbody fusion model. The cell-scaffold complex was implanted in the intervertebral space in group I, the collagen sponge scaffold was implanted in group II, and the autologous iliac crest spongy bone was implanted in group III. Palpation, radiography, micro-CT, and histology were performed on the 12th weeks after operation to evaluate osteogenesis and spinal fusion. RESULTS: BMSCs differentiated into osteoblasts in the cell-scaffold complex after osteogenic induction for 3 weeks. The spinal fusion rates in group I, II, and III were 40%, 0%, and 70%, respectively. Micro CT and histological examination showed mature bone marrow and trabecular bone formation in the fusion segments. The new bone was integrated with the upper and lower vertebral body. The bone trabecula in group III was stronger than group I. The surgical segments in group II was scar tissue without collagen sponge residue. CONCLUSIONS: BMSCs can induce osseous fusion in the lumbar vertebra. PMID- 30280762 TI - Targeted inhibition of beta-catenin by miR-320 and decreased MMP-13 expression in suppressing chondrocyte collagen degradation. AB - OBJECTIVE: Wnt/beta-catenin pathway plays a critical role in modulating embryonic development, cell growth, and differentiation. The over-expression of beta catenin activates this pathway and up-regulates expression of matrix metalloproteinase-13 (MMP-13), and promotes matrix degradation and occurrence of osteoarthritis (OA). This study aims to explore the effect of miR-320 expression in OA chondrocyte and underlying mechanisms. PATIENTS AND METHODS: Chondrocyte tissues from OA patients and normal individuals were collected for the detection of expression levels of miR-320, beta-catenin, MMP-13, and alpha-1 chain of type II collagen (COL2A1). Dual luciferase reporter assay was performed to test targeted regulation between miR-320 and beta-catenin. IL-1beta was used to simulate in vitro cultured chondrocytes, which were transfected with miR-320 mimic and/or si-beta-catenin, followed by quantification of miR-320, beta catenin, MMP-13, and COL2A1. RESULTS: In chondrocytes of OA patients, expression of microRNA (miR)-320 is decreased. Bioinformatics analysis revealed complementary binding sites between miR-320 and beta-catenin. Compared to control group, increasing levels of beta-catenin and MMP-13 expression with reduction of miR-320 and COL2A1 expressions were observed in OA chondrocytes. Transfection of miR-320 mimic and/or si-beta-catenin depressed expression of beta-catenin and MMP 13 inside chondrocytes, accompanied with elevation of COL2A1 expression. CONCLUSIONS: MiR-320 expression in OA chondrocyte is decreased, accompanied with up regulation of beta-catenin and MMP-13. MiR-320 can inhibit beta-catenin and MMP-13 expressions, elevates COL2A1 expression, which provides novel insights for the treatment of osteoarthritis. PMID- 30280763 TI - The down-regulation of long non-coding RNA LINC01088 is associated with the poor prognosis of epithelial ovarian cancer patients. AB - OBJECTIVE: Long intergenic non-coding RNA 1088 (LINC01088) has been suggested to act as a tumor suppressor in epithelial ovarian cancer (EOC); however, the prognostic role of LINC01088 has not been evaluated in cancer patients. This study aimed to investigate the expression of LINC01088 in EOC, along with evaluating its clinical-pathological and prognostic importance. PATIENTS AND METHODS: A bioinformatics tool (GEPIA) was used to screen the dysregulated lncRNAs. Quantitative Real-time PCR (qRT-PCR) was used to measure expression level of LINC01088 in EOC tumor samples and adjacent non-tumor tissues. Then, the association between LINC01088 expression and pathological parameters were further evaluated. Overall survival (OS) was estimated using the Kaplan-Meier method, and the differences in survival were compared using the log-rank test. Univariate and multivariate analysis were performed using the Cox proportional hazard analysis. RESULTS: We found that LINC01088 expression was significantly down-regulated in EOC tissues via "GEPIA". Then, the results of RT-PCT confirmed that the expression levels of LINC01088 were significantly lower in EOC tissues compared to adjacent noncancerous tissues (p < 0.01). Interestingly, lower LINC01088 expression levels were associated with FIGO stage (p = 0.000), grade (p = 0.003) and distant metastasis (p = 0.006). Moreover, Kaplan-Meier analysis indicated that patients with low LINC01088 expression had a poor overall survival (p = 0.0013). Finally, univariate and multivariate analysis show that LINC01088 expression is an independent predictor for overall survival. CONCLUSIONS: Low LINC01088 expression was associated with the progression of EOC and could serve as a potential independent prognostic biomarker for patients with EOC. PMID- 30280764 TI - miR-532-5p is a prognostic marker and suppresses cells proliferation and invasion by targeting TWIST1 in epithelial ovarian cancer. AB - OBJECTIVE: Dysregulated miR-532-5p has been observed in epithelial ovarian cancer (EOC). However, the potential biological function and clinical significance have not been fully explained. The study aimed to investigate the prognostic value and potential role of miR-532-5p in EOC. PATIENTS AND METHODS: MiR-532-5p and Twist homolog 1 (TWIST1) mRNA expression were examined using quantitative real-time PCR. The correlation of miR-532-5p expression with clinicopathological factors was statistically analyzed. Kaplan-Meier analysis and Cox proportional hazards regression models were explored to reveal the correlations of miR-532-5p expression with survival of patients. Cell Counting Kit-8, colony formation and transwell invasion assays were performed to evaluate the effects of miR-532-5p on cell proliferation and invasion, respectively. MiR-532-5p target genes were confirmed using luciferase activity, RT-PCR and Western blot assays. RESULTS: We found that miR-532-5p was significantly decreased in EOC tissue and cell lines, and its expression levels were highly correlated with grade (p = 0.011), FIGO stage (p = 0.004) and distant metastasis (p = 0.008). In addition, overall patient survival for those with high miR-532-5p expression was significantly longer than those patients with low miR-532-5p expression (p = 0.0058). Multivariate regression analysis identified miR-532-5p down-regulation as an independent unfavorable prognostic factor in EOC patients. Function assays showed that overexpression of miR-532-5p inhibited proliferation, colony formation and invasion of EOC cells. Mechanistic investigations confirmed TWIST1 as a direct target of miR-532-5p. Further in vitro assay indicated that restored expression of TWIST1 dampened miR-532-5p-mediated suppression of tumor progression. CONCLUSIONS: Our data suggested that miR-532-5p may act not only as a novel prognostic marker, but also as a potential target for molecular therapy of EOC. PMID- 30280765 TI - Reduced expression of miR-564 is associated with worse prognosis in patients with osteosarcoma. AB - OBJECTIVE: MiR-564 has been reported to be involved in the development of several types of cancers. However, its clinical significance in osteosarcoma (OS) has not been investigated. We aimed to explore the prognostic value of miR-564 in OS patients. PATIENTS AND METHODS: Quantitative RT-PCR assay was used to detect the expression levels of miR-564 in OS tissues and matched normal bone tissues. The correlation between miR-564 expression and clinicopathological features was analyzed by Pearson's chi2-test. The disease-free survival and overall survival rates of OS patients were calculated by the Kaplan-Meier method. Cox regression analysis was used to assess factors related to survival. RESULTS: We observed that the level of miR-564 was significantly reduced in OS tissues compared with that in the paired noncancerous bone tissues (p < 0.01). In addition, low miR-564 expression was found to be closely correlated with advanced clinical stage (p = 0.000) and distant metastasis (p = 0.003). Furthermore, survival analyses showed that patients with low expression of miR-564 had a shorter overall survival (p = 0.001) and disease-free survival (p = 0.001) than those with high expression of miR-564. Finally, we showed that miR-564 was an independent poor prognostic factor for both 5-year overall survival (p = 0.001) and 5-year disease-free survival (p = 0.001) through multivariate analysis. CONCLUSIONS: Overall, our data for the first time suggest that downregulated miR-564 may be used as a novel prognosis predictor of OS. PMID- 30280766 TI - MiR-100 up-regulation enhanced cell autophagy and apoptosis induced by cisplatin in osteosarcoma by targeting mTOR. AB - OBJECTIVE: Mammalian target of rapamycin (mTOR) can negatively regulate cell autophagy, while its expression and activity are associated with the pathogenesis of osteosarcoma. MicroRNA 100 (MiR-100) down-regulation is associated with the pathogenesis and chemo-sensitivity of osteosarcoma. Bioinformatics analysis revealed the targeted relationship between miR-100 and the 3'-UTR of mTOR. We investigate the role of miR-100 in affecting mTOR expression, osteosarcoma cell autophagy, and sensitivity to cisplatin. PATIENTS AND METHODS: MiR-100, mTOR, and Beclin-1 expressions in osteosarcoma tissue and normal control were compared. The relationship between miR-100 and mTOR was verified by dual luciferase assay. MiR 100, mTOR, and Beclin-1 levels in MG-63 cells and MG-63/DDP cells were tested. Cell apoptosis was determined by using flow cytometry. Cell malignancy was evaluated by colony formation assay. RESULTS: MiR-100 and Beclin-1 significantly declined, while mTOR significantly increased in osteosarcoma tissue compared with that of normal tissue (p<0.05). MiR-100 targeting significantly inhibited mTOR expression compared to that of untreated (p<0.05). MiR-100 expression was down regulated and mTOR level was elevated in MG-63/DDP cells compared with MG-63 cells (p<0.05). MG-63/DDP cells exhibited reduced cell autophagy and apoptosis, and enhanced colony formation induced by DDP. MiR-100 mimic and/or small interfere mTOR (si-mTOR) significantly promoted Beclin-1 expression, cell autophagy, and cell apoptosis, while attenuated colony formation. CONCLUSIONS: MiR-100 declined, while mTOR up-regulated in osteosarcoma tissue. MiR-100 up regulation enhanced cell autophagy and apoptosis induced by cisplatin via targeted inhibiting of mTOR. PMID- 30280767 TI - LncRNA LINC00628 overexpression inhibits the growth and invasion through regulating PI3K/Akt signaling pathway in osteosarcoma. AB - OBJECTIVE: Osteosarcoma (OS) is the most common primary malignancy, mainly arising from the metaphysic of the long bones of adolescents and young adults. Although osteosarcoma has been studied widely, the underlying molecular mechanism remains unclear. Increasing evidence shows that abnormal long non-coding RNAs (LncRNAs) expression is involved in tumorigenesis. The aim of this study was to identify the detailed role of LncRNA LINC00628 in osteosarcoma. MATERIALS AND METHODS: The relative mRNA expression level of LINC00628 in adjacent tissues, osteosarcoma tissues with or without metastasis and osteosarcoma cell lines were detected by qRT-PCR. Overall survival curves for two groups defined by high and low expression level of LINC00628 in osteosarcoma patients. The cell proliferation, invasion and migration in osteosarcoma cells after transfection with lncRNA- NC or lncRNA-LINC00628 were detected. The cell cycle distribution and apoptosis rate in osteosarcoma cells after transfection with lncRNA- NC or lncRNA-LINC00628 were measured using the Flow cytometry analysis. The relative protein expression level of p-PI3K, p-Akt, P53 and Bcl-2 in osteosarcoma cells after transfection with lncRNA- NC or lncRNA-LINC00628 were detected by Western blot. RESULTS: LINC00628 expression was significantly decreased in osteosarcoma tissues compared with adjacent tissues. Meanwhile, osteosarcoma tissues with metastasis were significantly associated with a low expression level of LINC00628 and the low expression level of LINC00628 has a lower overall survival rate. LINC00628 expression was increased in osteosarcoma cell lines after transfection with lncRNA-LINC00628 and the cell proliferation, invasion and migration in osteosarcoma cells after transfection with lncRNA-LINC00628 were significantly inhibited. Moreover, the cell cycle was arrested in G0/G1 phase and the apoptosis rate was increased in osteosarcoma cells after transfection with lncRNA LINC00628. Mechanistically, the relative protein expression level of p-PI3K, p Akt and Bcl-2 were significantly increased and the relative expression of P53 was significantly decreased in osteosarcoma cells after transfection with lncRNA LINC00628. CONCLUSIONS: LINC00628 expression was decreased in osteosarcoma. The overexpression of LINC00628 inhibited the proliferation, invasion and migration and promoted cell apoptosis in osteosarcoma cells through the inactivation of PI3K/Akt signaling pathway. This lncRNA may be involved in the development and progression of osteosarcoma. PMID- 30280768 TI - Biomarkers and new therapeutic targets in renal cell carcinoma. AB - OBJECTIVE: Renal Cell Carcinoma (RCC) is the most common malignancy in adult kidneys. The American Cancer Society estimated 62,700 new cases and 14,240 deaths in 2018. Although early detection has improved in recent years, the treatment remains a challenge and reliable biomarkers for poor outcomes become necessary for the prevention of metastases and improve the quality of patients' life during and after treatment. Then, the current status of the search for new RCC biomarkers was discussed, as well as the latest discoveries in the RCC risk and metastatic treatment were discussed in this review. MATERIALS AND METHODS: Extensive research was carried out in the online databases and full-free text articles published in the last 5 years, or more when convenient, were evaluated. Articles were included that addressed the proposed theme and were published in the English language. RESULTS: The present state of knowledge on biomarkers for RCC carcinogenesis and progression is still much to be understood about RCC risk factors and molecular pathways resulting in metastatic progression. Newest RCC target therapies were discussed, mainly in relation to immunological therapy, and vaccines that have been tested in numerous trials with different cancer types. CONCLUSIONS: The development of targeted therapies has revolutionized the treatment of advanced and metastatic cancers or non-responder patients. Combined therapy between classical chemotherapy and adjuvant immunotherapies has been modifying the cancer patients prognosis and bringing the hope of a cure in many cases. PMID- 30280769 TI - Evaluating the diagnostic and prognostic value of long non-coding RNA SNHG15 in pancreatic ductal adenocarcinoma. AB - OBJECTIVE: Long non-coding RNA SNHG15 (SNHG15) has been reported to play very important roles in the malignancy behaviors of various tumors, including pancreatic ductal adenocarcinoma (PDAC). However, its clinical significance in PDAC remains largely unclear. The aim of this study was to investigate whether the aberrant expression of SNHG15 can be used as potential prognostic and diagnostic markers of human PDAC. MATERIALS AND METHODS: TaqMan Real Time-PCR was performed to investigate the expression of SNHG15 in PDAC tissues and serum samples. Receiver operator characteristic (ROC) analysis was applied to obtain the diagnostic utility of SNHG15. Association between SNHG15 levels and clinicopathological factors was analyzed. Kaplan-Meier curves and multivariate Cox proportional models were used to study the impact on clinical outcome. RESULTS: SNHG15 levels were significantly up-regulated in both sera and tumors tissues from PDAC patients. ROC curve analysis revealed that SNHG15 may be a potential biomarker for differentiating PDAC tissues from normal pancreatic tissues, and the plasma levels of SNHG15 may be a potential biomarker for differentiating PDAC patients from healthy controls. Clinicopathologic analysis revealed that high SNHG15 expression was associated with tumor differentiation (p = 0.000), lymph node metastasis (p = 0.001) and tumor stage (p = 0.005). Furthermore, patients with high SNHG15 expression had a shorter overall survival compared with the low SNHG15 expression group (p = 0.003). Also, Cox multivariate analyses confirmed that SNHG15 expression was an independent prognostic factor in PDAC (p < 0.004). CONCLUSIONS: Our study firstly indicated the potential value of SNHG15 as an important biomarker for the diagnosis and prognosis prediction of PDAC. PMID- 30280770 TI - MicroRNA-23a induces apoptosis of hepatocarcinoma cell line MHCC97H via down regulating KIAP: a mechanism study. AB - OBJECTIVE: Hepatocarcinoma is a great threat to global health. MicroRNA-23a was suggested to regulate growth and apoptosis in certain cell lines. Our study was focused on growth, proliferation, and apoptosis of hepatocarcinoma cell line MHCC97H under the influence of microRNA-23a, and explored the mechanism of pro apoptosis microRNA-23a. MATERIALS AND METHODS: MicroRNA-23a and control microRNA (scramble miRNA, for short as miRNA) were synthesized with the routine protocol. Lipofection transfection was performed in hepatocarcinoma cell line MHCC97H. 3 (4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay, caspase-3 activity detection, and flow cytometry were performed to examine growth, proliferation, and apoptosis of hepatocarcinoma cell line MHCC97H, respectively. Kidney inhibitor of apoptosis protein (KIAP) and small interfere RNA (siRNA) was synthesized for inhibition of KIAP. KIAP plasmid was established for activation of KIAP. Western blot was performed to examine the protein expression of KIAP and caspase protein family after transfection of KIAP siRNA or KIAP plasmid. RESULTS: Compared with miRNA transfection, microRNA-23a transfection significantly reduced the growth of MHCC97H cells, and decreased the expression of KIAP (p < 0.05). Enhanced translocation of phosphatidylserine and activation of caspase-3 were observed in microRNA-23a transfection cells. Moreover, inhibition of KIAP enhanced the pro-apoptosis effect of microRNA-23a, while activation of KIAP abrogated pro-apoptosis effect of microRNA-23a. CONCLUSIONS: MicroRNA-23a inhibits growth and proliferation of MHCC97H cells, and induces apoptosis of MHCC97H cells via down-regulating KIAP. KIAP could be a potential therapeutic target for hepatocarcinoma treatment. PMID- 30280771 TI - Expressions of HBV X gene regulated by different promoters and their effects on cell apoptosis. AB - OBJECTIVE: To investigate the difference in expression level of hepatitis B virus (HBV) X gene, and to further study the difference of HBV X protein (HBx) at varied expression levels in apoptosis regulation of hepatocellular carcinoma cells. The recombinant plasmid rPX with HBV enhancer 1 (Enh1), X gene promoter, X gene and polyA tail were constructed, respectively. PATIENTS AND METHODS: HepG2 cells were transiently transfected with the recombinant plasmids and control vector pGEM(r)-7Zf (+) by virtue of Fugene(r)HD; reverse transcription PCR (RT PCR) and Western blotting were applied to analyze the transcription and expression of HBV X gene as well as the difference in the expression level in multiple groups. The activity of the transfected cells in each group was detected by using the methyl thiazolyl tetrazolium (MTT) method for 6 consecutive days after transfection. A flow cytometer was utilized to measure the cell apoptosis rate. RESULTS: The RT-PCR results showed that messenger RNA expression of HBV X gene was detected in all HepG2 cells transfected by different recombinant plasmids, of which the relationships of the expression levels were rCX>rEX1 and rEX2> rPX (p<0.05). Only HepG2/rCX cells in each group of transfected cells showed HBx expression by Western blot. MTT method revealed that there were notable differences between HepG2/rCX, HepG2/rEX1, HepG2/rPX and HepG2/pGEM(r) 7Zf (+) (p<0.05). The apoptosis rates of HepG2/rCX, HepG2/rEX1 and HepG2/rPX were significantly higher than that of HepG2/pGEM(r)-7Zf (+) (p<0.05). CONCLUSIONS: HBx can promote cell apoptosis. Results of this research also indicate that there is a significant difference in the pro-apoptotic role of HBx when its expression is regulated by different promoters, and such a difference may be a part of the complex pathogenic mechanisms of HBV and hepatocellular carcinoma. PMID- 30280772 TI - Down-regulation of miR-1236-3p is correlated with clinical progression and unfavorable prognosis in gastric cancer. AB - OBJECTIVE: MiRNAs have been considered to participate in many processes of various cancers, including gastric cancer (GC). However, the significance of miRNAs in the progression prognosis of GC is largely unknown. The goal of this study was to determine the expression level of miR-1236-3p in GC and its clinical association. PATIENTS AND METHODS: Clinical specimens from GC patients were obtained to quantify the expression level of miR-1236-3p using quantitative Real time PCR. The correlation between the miR-1236-3p levels and the clinicopathological factors of the GC patients was analyzed. The association between miR-1236-3p expression and overall survival was estimated by the Kaplan Meier method. The significance of different variables with respect to survival was analyzed using the univariate and multivariate Cox proportional hazards model. RESULTS: We found that miR-1236-3p was significantly downregulated in GC tissues compared to non-tumor gastric tissues (p < 0.01). The levels of miR-1236 3p expression were associated significantly with clinical stage (p = 0.002), lymph node metastasis (p = 0.000) and distant metastasis (p = 0.017). Kaplan Meier survival analysis showed that patients in the high miR-1236-3p expression group had better overall survival than those in the low miR-1236-3p expression group (p = 0.0039). Moreover, we confirmed that miR-1236-3p was an independent poor prognostic factor for GC patients through univariate and multivariate analysis. CONCLUSIONS: Our findings provide evidence that miR-1236-3p expression is frequently decreased in GC tissues, and its low expression may be a significant prognostic factor for poor survival in GC patients. PMID- 30280773 TI - Expression and prognosis of MYOZ2 in gastric cancer. AB - OBJECTIVE: To investigate the expression of human myozenin 2 (MYOZ2) in cancer tissues and its effect on the prognosis of patients with gastric cancer. PATIENTS AND METHODS: Gastric cancer tissue and adjacent normal tissue specimens were obtained from a total of 258 patients together with complete clinicopathological data. Those patients were treated in Harbin Medical University Cancer Hospital from March 2007 to March 2012. Quantitative Real Time-Polymerase Chain Reaction (RT-PCR) was used to detect the expression of MYOZ2 messenger RNA (mRNA) in gastric cancer tissues and normal gastric tissues, and correlations between the expression level of MYOZ2 in gastric cancer tissues and the clinicopathological parameters of patients were analyzed. MYOZ2 protein expression levels in different gastric cancer cells were detected by Western blotting; transwell chamber assay was used to detect the effect of MYOZ2 expression on the in-vitro migration and invasion abilities of gastric cancer cells; 3-(4,5-Dimethylthiazol 2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was applied to examine the in vitro proliferation and growth abilities of gastric cancer cells. RESULTS: The expression level of MYOZ2 mRNA in gastric cancer tissues was significantly higher than that in cancer-adjacent tissues in 258 cases (p<0.05). Western blotting results showed that the expression level of MYOZ2 protein in gastric cancer tissues was significantly increased compared with that in the corresponding adjacent healthy tissues (p<0.05). In-vitro growth, migration and invasion abilities of MYOZ2 positive gastric cancer cells were significantly higher than those of normal tissue cells. Univariate analysis showed that the high expression level of MYOZ2 in gastric cancer tissues was closely related to tumor size, lymph node metastasis, and pathological tumor-node-metastasis (pTNM) staging (p<0.05), but not associated with gender, age, differentiation degree, and tumor location (p>0.05). The 1-, 3- and 5-year survival rates of patients with low expression level of MYOZ2 (n=130) were higher than those of patients with high expression level of MYOZ2 (n=128). Multivariate analysis revealed that the expression level of MYOZ2 (p=0.000), lymph node metastasis (p=0.002), and pTNM staging (p=0.015) were independent risk factors influencing the prognosis of gastric cancer. CONCLUSIONS: Our results showed that the expression level of MYOZ2 may play an important role in the occurrence and development of gastric cancer, and can also provide references for the clinical diagnosis and treatment of gastric cancer. PMID- 30280774 TI - CD82/KAI1 inhibits invasion and metastasis of esophageal squamous cell carcinoma via TGF-beta1. AB - OBJECTIVE: Previous studies have found that CD82/KAI1 is a tumor suppressor gene. However, the role of CD82/KAI1 in esophageal squamous cell carcinoma (ESCC) has not been reported. This study aims to investigate the specific role of CD82/KAI1 in ESCC, so as to further explore the relationship between CD82/KAI1 expression and clinical characteristics of ESCC. PATIENTS AND METHODS: The expression of CD82/KAI1 in 96 pairs of ESCC tissues and adjacent normal tissues was detected by Real-time quantitative polymerase chain reaction (qRT-PCR). The relationship between CD82/KAI1 expression and the pathological indicators of ESCC patients was analyzed by Kaplan-Meier method. QRT-PCR further validated the expression level of CD82/KAI1 in ESCC cells. In addition, the CD82/KAI1 knockdown expression model was constructed using small interfering RNA in ESCC cell lines TE-1 and EC-109 cells. Cell counting kit-8 (CCK-8) and transwell assay were performed to detect cell viability, invasion and migration. Finally, the potential mechanism of CD82/KAI1 in regulating ESCC was explored using Western blot. RESULTS: QRT-PCR results showed that the expression level of CD82/KAI1 in ESCC was significantly lower than that of normal tissues, and the difference was statistically significant. Higher rates of lymph node metastasis and distant metastasis, as well as shorter overall survival were observed in ESCC patients with lower expression of CD82/KAI1 compared with those with higher expression. CD82/KAI1 overexpression decreased cell proliferation, invasion and metastasis in ESCC cells. Western blot results showed that the expressions of TGF-beta1, Smad2/3, MMP-2 and MMP-9 were regulated by CD82/KAI1. In addition, rescue experiments demonstrated an interaction between CD82/KAI1 and TGF-beta1, indicating that CD82/KAI1 inhibits the malignant progression of ESCC via regulating TGF-beta1. CONCLUSIONS: Lowly expressed CD82/KAI1 in ESCC was significantly associated with the pathological stage, distant metastasis and poor prognosis of ESCC patients. CD82/KAI1 may inhibit the malignant progression of ESCC by interacting with TGF beta1. PMID- 30280775 TI - High expression of lncRNA MEG3 participates in non-small cell lung cancer by regulating microRNA-7-5p. AB - OBJECTIVE: This study was made to investigate whether long noncoding RNA (lncRNA) MEG3 could participate in the occurrence and development of non-small cell lung cancer (NSCLC) by regulating the expression of BRCA1 through competitive binding to microRNA-7-5p. PATIENTS AND METHODS: We used quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) to explore the expression of lncRNA MEG3 and BRCA1 in NSCLC tissues and adjacent normal tissues, as well as NSCLC cell lines. The dual luciferase reporter gene assay was used to detect the binding of microRNA-7-5p to lncRNA MEG3 and BRCA1. Meanwhile, the expression of BRCA1, B-cell lymphoma-2 (Bcl 2) and BCL2-associated X (Bax) was detected by Western blot after the cells were overexpressed or knocked down of lncRNA MEG3. All these experiments were designed to investigate whether lncRNA MEG3 participated in the pathogenesis of NSCLC through inhibiting the expression of BRCA1 and Bcl-2 and promoting Bax expression. RESULTS: The expressions of lncRNA MEG3 and BRCA1 in NSCLC tissues and A549 and HCC823 cell lines were significantly lower than those in the normal group. Overexpression of lncRNA MEG3 and BRCA1 in A549 and HCC823 cell lines resulted in increased apoptosis of lung cancer cells. Dual luciferase reporter assay demonstrated that lncRNA MEG3 can regulate the expression of BRCA1 through competitively binding to microRNA-7-5p to form the lncRNA MEG3/microRNA-7 5p/BRCA1 regulatory network. Besides, lncRNA MEG3 could inhibit the apoptosis inhibitory protein Bcl-2 and promote the expression of apoptosis-promoting factor Bax. CONCLUSIONS: LncRNA MEG3 was significantly downregulated in NSCLC, and it could regulate the BRCA1 expression by competitive binding to microRNA-7-5p. PMID- 30280776 TI - LncRNA H19 serves as a ceRNA and participates in non-small cell lung cancer development by regulating microRNA-107. AB - OBJECTIVE: To investigate whether lncRNA H19 can regulate NF1 expression through competitive binding to microRNA-107, thereby participating in the occurrence and development of non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Expression levels of H19 and NF1 in NSCLC tissues, paracancerous tissues and NSCLC cell lines were detected by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). The binding condition of microRNA-107, H19 and NF1 was detected by dual-luciferase reporter gene assay. Corresponding lentiviruses of H19 were constructed. The regulatory effects of H19 on proliferative and migratory abilities of A549 cells were detected by cell counting kit-8 (CCK-8) and transwell assay, respectively. Rescue experiments were conducted to explore the regulatory interaction between H19 and microRNA-107 in A549 cells. RESULTS: H19 and NF1 were highly expressed in NSCLC tissues and NSCLC cell lines (A549 and HCC823) than those of controls. Overexpressed H19 increased proliferative and migratory abilities of A549 cells. Dual-luciferase reporter gene assay demonstrated that H19 regulates NF1 expression through competitive binding to microRNA-107, thereafter participating in NSCLC development. CONCLUSIONS: H19 is highly expressed in NSCLC, which promotes NSCLC development by regulating NF1 via competitive binding to microRNA-107. PMID- 30280777 TI - MicroRNA-590-5p suppresses the proliferation and invasion of non-small cell lung cancer by regulating GAB1. AB - OBJECTIVE: Some specific microRNAs (miRNAs) have been identified to regulate the tumorigenesis of non-small cell lung cancer (NSCLC). MiR-590-5p was found to involve in the carcinogenesis of human cancers. This study aims at exploring the role of miR-590-5p in the pathogenesis of NSCLC. PATIENTS AND METHODS: The expressions of miR-590-5p and GAB1 were measured by quantitative Real-Time Polymerase Chain Reaction (qRT-PCR) and Western blot, respectively. The biological functions of miR-590-5p and GAB1 on cell viability and invasion were investigated through MTT and transwell assays. The binding site between miR-590 5p and GAB1 was verified by dual-luciferase reporter gene assay (DLR). RESULTS: MiR-590-5p expression was downregulated in NSCLC. MiR-590-5p overexpression inhibited the proliferation and invasion of NSCLC cells. Furthermore, miR-590-5p was confirmed to directly target GAB1. GAB1 knockdown had the same effect as overexpression of miR-590-5p in NSCLC. Moreover, overexpression of GAB1 partially reversed the suppressive effect of miR-590-5p on NSCLC. CONCLUSIONS: MiR-590-5p suppressed cell proliferation and invasion of NSCLC by inhibiting GAB1 expression, indicating that miR-590-5p was a suppressive miRNA in NSCLC. PMID- 30280778 TI - MiR-940 inhibits the progression of NSCLC by targeting FAM83F. AB - OBJECTIVE: We investigate whether miR-940 could target family sequence similarity 83 member F (FAM83F) and further inhibit the progression of non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: The expression levels of miR-940 and FAM83F in tumor tissues and paracancerous tissues of 72 NSCLC patients were detected through quantitative real time-polymerase chain reaction (qRT-PCR). The relationship between their expression levels, tumor size, and prognosis of NSCLC was analyzed. Transfection plasmids were constructed to knockdown or overexpress miR-940 in H1299 cells (inhibitor group) and SK-MES-1 cells (mimic group). The viability of H1299 cells and SK-MES-1 cells was evaluated using cell counting kit 8 (CCK-8) assay after transfection. The combination of miR-940 and Ago2 was confirmed by RNA immunoprecipitation (RIP) experiment. The binding condition of miR-940 in FAM83F-WT and FAM83F-MUT groups was verified by luciferase reporter gene assay. RESULTS: MiR-940 expression was noticeably decreased, while FAM83F expression was distinctly upregulated in NSCLC tissues than that of paracancerous tissues. The overall survival rate of NSCLC patients with highly-expressed miR 940 was significantly higher than those with lowly-expressed miR-940. Besides, miR-940 level was negatively correlated with tumor stage and size of NSCLC patients. Knockdown of miR-940 evidently enhanced the activity of H1299 cells, while overexpression of miR-940 decreased the viability of SK-MES-1 cells. In addition, miR-940 was confirmed to combine with FAM83F. Luciferase activity of cells co-transfected with FAM83F-WT and miR-940 mimic was significantly decreased. CONCLUSIONS: MiR-940 inhibited the proliferation of cancer cells by targeting FAM83F and further restrained the progression of NSCLC. PMID- 30280779 TI - MicroRNA-217 alleviates development of non-small cell lung cancer by inhibiting AKT3 via PI3K pathway. AB - OBJECTIVE: To explore the role of microRNA-217 in non-small cell lung cancer (NSCLC) and its underlying mechanism. PATIENTS AND METHODS: MicroRNA-217 expression in 48 NSCLC tissues and paracancerous tissues were detected by qRT-PCR (quantitative Real-time polymerase chain reaction). The relationship between microRNA-217 expression and prognosis of NSCLC patients was analyzed. Target gene of microRNA-217 was predicted by bioinformatics method and further verified by luciferase reporter gene assay. Cell proliferation, cell cycle and apoptosis were detected after altering microRNA-217 expression in NSCLC cells. The effect of microRNA-217 on regulating PI3K pathway was detected by Western blot. RESULTS: MicroRNA-217 was downregulated in NSCLC tissues than that of paracancerous tissues. Shorter overall survival (OS) was observed in NSCLC patients with lower expression of microRNA-217 than those with higher expression. Overexpressed microRNA-217 remarkably inhibited proliferation and cell cycle, whereas induced apoptosis of NSCLC cells. AKT3 was screened out to be the target gene of microRNA 217. Western blot results demonstrated that microRNA-217 upregulated AKT3 and PI3K pathway-related genes. CONCLUSIONS: Downregulated microRNA-217 promotes the occurrence and progression of NSCLC through upregulating AKT3 via PI3K pathway. PMID- 30280780 TI - HDAC1 is indirectly involved in the epigenetic regulation of p38 MAPK that drive the lung cancer progression. AB - OBJECTIVE: p38 MAPK are a class of protein kinase that may induce or prevent apoptosis in different circumstance. Emerging researches show that it plays a vital role in tumor progression and therefore understanding its dual role in different stages of lung cancer are important to investigate. Also in this study, we planned to understand its upstream target proteins like HDAC1 and uPAR which are responsible for p38 MAPK activation in the pathway. MATERIALS AND METHODS: We initially develop lung cancer mice model by exposing them to high nicotine content tobacco smoke. The pathological stages of initial and advanced lung cancer are observed and confirmed through histological sectioning. The expression of HDAC1, uPAR and p38 MAPK are observed and analyzed in different stages of lung cancer using immunohistochemistry and Western blotting. RESULTS: After 4 and 6 months of regular exposure of high nicotine content smoke, the A/J strain mice develop initial and advanced stage of lung cancer. The initial stage cancer develops thick tissue layers with fibrosis whereas advanced stages of lung cancer show more proliferative cells. The expression of HDAC1 and uPAR shows the minimal expression pattern in control and initial stages of lung cancer, but its expression increased in advanced stage of cancer. In case of phospho-p38 MAPK, mild expression was observed almost in every individual cell in the initial stages of cancer, which implies its protective role in preventing advanced stage of cancer. But in advanced stage of lung cancer, we observed dysregulated overexpression of phospho-p38 MAPK. CONCLUSIONS: The epigenetic regulation of uPAR by HDAC1 confirms its indirect role in regulating p38 MAPK as tumor progress. PMID- 30280781 TI - MiR-410 affects the proliferation and apoptosis of lung cancer A549 cells through regulation of SOCS3/JAK-STAT signaling pathway. AB - OBJECTIVE: Janus kinase (JAK) - signal transducer and activator of transcription (STAT) signal pathway participates in regulating cell proliferation, differentiation, and apoptosis, and is correlated with non-small cell lung cancer (NSCLC) onset. Suppressors of cytokine signaling 3 (SOCS3) negatively regulates JAK-STAT pathway. SOCS3 is down-regulated in NSCLC tissues, with an elevation of miR-410 expression. This study thus intends to investigate if miR-410 plays a role in mediating NSCLC onset and underlying mechanism in this regulatory process. PATIENTS AND METHODS: NSCLC patients were collected for tumor and adjacent tissues, among which, miR-410 and SOCS3 expression were measured. Dual luciferase reporter gene assay was employed to confirm the targeting relationship between miR-410 and SOCS3. Their expression levels were compared between A549 and BEAS-2B cells. Cultured A549 cells were treated with anti-miR-410 and/or SOCS3. Expression levels of SOCS3, p-JAK1/2, p-STAT3, and Bcl-2 were compared along with the apoptotic rate of cells. RESULTS: Bioinformatics analysis revealed targeted binding site between miR-410 and 3'-UTR of SOCS3 mRNA. Compared to those in tumor tissues, a significant increase of miR-410 and reduction of SOCS3 were found in NSCLC tissue (p < 0.05). Dual luciferase reporter gene assay indicated that SOCS3 was targeted regulated by miR-410. Significantly higher miR-410 and lower SOCS3 levels were shown in A549 cells, compared to those in BEAS-2B cells. Transfection of anti-miR-410 and/or SOCS3 in A549 cells, SOCS3 expression and apoptosis were significantly induced, while JAK1, JAK2, and STAT3 phosphorylation were statistically decreased with the reduction of the Bcl-2 level (p < 0.05). CONCLUSIONS: miR-410 level was increased while SOCS3 expression was declined in NSCLS tissues. MiR-410 induces the apoptosis of A549 cells through downregulating JAK/STAT3/SOCS3 signaling pathway, which provides new insights for the therapy of pulmonary carcinoma in clinic. PMID- 30280782 TI - MiR-410 affects the proliferation and apoptosis of lung cancer A549 cells through regulation of SOCS3/JAK-STAT signaling pathway. AB - OBJECTIVE: Larynx carcinoma is a common head-neck malignant tumor. Recent investigations showed the involvement of microRNA (miR) in regulation of multiple tumors. miR-140-5p showed decreased expression in various cancers, but without knowledge regarding its expression in larynx carcinoma and effects on cell invasion and angiogenesis. MATERIALS AND METHODS: Real-time quantitative PCR was firstly employed to measure miR-140-5p expression in larynx carcinoma and controlled tumor adjacent tissues. In larynx cancer cell line, agomir or antagomir of miR-140-5p was applied to up-regulate or down-regulate miR-140-5p, respectively. Western blot was used to evaluate vascular endothelial growth factor A (VEGF-A) expression, and cell proliferation was modified by 3-(4,5 dimethyl-2-thiazolyl)-2,5-diphenyl-2-H- tetrazolium bromide (MTT) approach. Transwell approach was used to measure cell invasion, and angiogenesis assay was used to detect the effect on angiogenesis. Luciferase report assay (LRA) measured targeting binding between miR-140-5p and VEGF-A. RESULTS: Comparing to tumor adjacent tissues, larynx carcinoma cells showed significantly decreased miR-140 5p expression. Agomir up-regulated miR-140-5p expression and weakened proliferation and invasion potency, and inhibited angiogenesis. Antagomir down regulated miR-140-5p and presented the opposite results. Finally, LRA confirmed direct binding between miR-140-5p and VEGF-A. CONCLUSIONS: MiR-140-5p can target VEGF-A in larynx carcinoma cell line to inhibit cell invasion and angiogenesis. MiR-140-5p thus may work as the direct molecular target of larynx carcinoma. PMID- 30280783 TI - LncRNA LET function as a tumor suppressor in breast cancer development. AB - OBJECTIVE: To evaluate the effect of long-chain non-coding RNA LET (lncRNA LET) on the regulatory of human breast cancer and its underlying mechanism. PATIENTS AND METHODS: The expression levels of lncRNA LET in breast cancer tissues, MDA-MB 231 cells and MCF-10A breast epithelial cells were detected by quantitative Real Time Polymerase Chain Reaction (qRT-PCR). The proliferation of lncRNA LET was detected by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide). Cell apoptosis was examined via flow cytometry. The invasion and migration of cells were detected by transwell and scratch assay. RESULTS: The expression of lncRNA LET was reduced in breast cancer tissues and MDA-MB-231 cells. Overexpression of lncRNA LET resulted in the inhibition of cell proliferation, invasion and migration ability, and promotion of cell apoptosis (p<0.05). Up regulation of lncRNA LET repressed epithelial mesenchymal transition (EMT) process. CONCLUSIONS: LncRNA LET is a new type of molecule involved in the development of breast cancer, which may become a potential target for the treatment of breast cancer. PMID- 30280784 TI - Jagged2 promotes cancer stem cell properties of triple negative breast cancer cells and paclitaxel resistance via regulating microRNA-200. AB - OBJECTIVE: To investigate the role of Jagged2 in triple negative breast cancer (TNBC) and its underlying mechanism. PATIENTS AND METHODS: Breast cancer tissues of patients diagnosed with TNBC in Fujian Medical University Affiliated MinDong Hospital from January 2015 to September 2017 were selected. TNBC patients were divided into the paclitaxel-resistant group (n=34) and non-resistance group (n=11). Jagged2 expression in paclitaxel-resistant group and non-resistance group before and after treatment was detected by quantitative Real-time-polymerase chain reaction (qRT-PCR), respectively. After Jagged2 knockdown in paclitaxel resistant MDA-MB-231 cells (MDA-MB-231/TXR), expression of CD44+CD24-ESA+ subset was detected by flow cytometry. MicroRNA-200 expression was detected after Jagged2 knockdown in MDA-MB-231/TXR cells. RESULTS: Jagged2 was highly expressed in paclitaxel-resistant TNBC tissues and cells. Jagged2 expression was found to be associated with cancer stem cell (CSC) properties of TNBC cells. Knockdown of Jagged2 inhibited CSC properties and paclitaxel resistance, whereas upregulated microRNA-200 expression. The inhibited CSC properties and paclitaxel resistance induced by Jagged2 knockdown were reversed by microRNA-200 knockdown. CONCLUSIONS: Jagged2 maintains CSC properties of TNBC cells and paclitaxel resistance via regulating microRNA-200. PMID- 30280785 TI - Central nervous disease in pediatric patients during acute lymphoblastic leukemia (ALL): a review. AB - Acute lymphoblastic leukemia (ALL) is one of the frequently reported malignancies of childhood age. Earlier it was thought to be a fatal pathological state with no cure, but with advancements in medicine and science, new therapeutic approaches have resulted in better management and cure. However, one of the major hurdles in achieving a complete cure is the relapse of ALL at extra-medullary sites like the central nervous system (CNS). The present review article is focused on recent diagnostic avenues available for the detection of CNS disease during acute lymphoblastic leukemia (ALL) in young patients. PMID- 30280786 TI - The therapeutic efficacy of pediatric ALL patients with MLL gene rearrangement treated with CCLG-ALL2008 protocol. AB - OBJECTIVE: In this study, we retrospectively evaluated the therapeutic efficacy of China Children Leukemia Group-ALL2008 (CCLG-ALL 2008) protocol in pediatric patients with mixed-lineage leukaemia (MLL) gene rearrangement of acute lymphoblastic leukemia (ALL) to identify the prognostic factors. PATIENTS AND METHODS: Six hundred and thirty-four patients with ALL were enrolled in this study between June 2008 and Dec 2014. High-risk group (HR) consisted of 217 cases, of which 28 cases were MLL related positive (first group), 22 cases were BCR/ABL positive (second group), and 167 cases were negative with MLL related or BCR/ABL (third group). The therapeutic efficacy was evaluated at the time points of day 8 (TP1), day 15 (TP2), day 33 (TP3) and 12th week (TP4) with the protocol, respectively. Overall-survival (OS) and relapse-free-survival (RFS) and treatment related mortality (TRD) were analyzed as well. RESULTS: The first group accounted for 4.4% of all patients. Compared with the second and third group, the first group had more cases younger than 2 years, with initial leukocytes >=50*109/L, and poor response on TP2. Moreover, patients older than 2 years old had a good 5 years OS (84% +/- 9% vs. 37% +/- 20%, p<0.05) and RFS (84% +/- 9% vs. 29% +/- 17%, p<0.05). There were no significant differences in the recurrence rate, TRD, 5 years OS and RFS among three groups. For the first group, compared with good response to prednisone, patients with poor response to prednisone had a poor 5 years RFS (41% +/- 17% vs. 81% +/- 10%, p<0.05). Multivariate Cox regression analysis identified that RFS and OS were influenced by such factors as age, MLL fusion partners, and prednisone response (p<0.05). CONCLUSIONS: Such factors as younger age than 2 years old, MLL/AF4 fusion gene, poor response to prednisone, or no complete remission (CR) on TP3 were poor prognostic parameters in predicting the outcome in childhood ALL with MLL gene rearrangement treated with CCLG-ALL 2008 protocol. PMID- 30280787 TI - DUSP facilitates RPMI8226 myeloma cell aging and inhibited TLR4 expression. AB - OBJECTIVE: Myeloma severely threatens public health, and molecular targeting treatment becomes the future perspective. Dual specificity phosphatases (DSUP) protein has multiple functions including modulating cell proliferation, differentiation, aging, and apoptosis. Whether DUSP can regulate myeloma cell is unclear. This study thus aimed to investigate the effect of DUSP on myeloma cell line RPMI8226 cell aging and provide evidence for the clinical treatment of myeloma. MATERIALS AND METHODS: H2O2-induced aging model of myeloma cell line RPMI8226 was generated. DUSP over-expression plasmid or specific siRNA was transfected by liposome. Western blot was used to detect the expression of DUSP in RPMI8226 cells. Cell aging condition was evaluated by beta-galactosidase assay. Aging proteins P53 and P16 expression levels, the activation of TLR4 signal pathway were tested by immunoblotting. TLR4 signal pathway was then suppressed by Verteporfin for testing RPMI8226 cell aging. RESULTS: Growing levels of DUSP, aging proteins P53 and P16, with inhibition of TLR4 signal pathway were found in the H2O2-induced aging model of myeloma cell line RPMI8226. Transfection of DUSP over-expression plasmid or siRNA potentiated or inhibited the aging of RPMI8226 cells induced by H2O2 and suppressed or enhanced TLR4 signal pathway, respectively. Verteporfin, an inhibitor of TLR4, increased the level of P53 and aging of RPMI8226 cells. CONCLUSIONS: DUSP facilitates H2O2 induced aging of myeloma cell line RPMI8226 and suppresses TLR4 expression, which provides academic basis for clinical intervention. PMID- 30280788 TI - SETD5-AS1 stimulates neuron death in stroke via promoting PTEN expression. AB - OBJECTIVE: To investigate the specific role of long non-coding RNA (lncRNA) SETD5 AS1 in regulating stroke development, and its underlying mechanism. MATERIALS AND METHODS: Middle cerebral artery occlusion (MCAO) model and OGD/R (oxygen-glucose deprivation/reoxygenation) model were constructed for exploring the mechanism of ischemia-reperfusion injury induced by ischemic stroke. SETD5-AS1 expression in brain tissues of ischemic stroke mice and control mice was detected by quantitative Real-time-polymerase chain reaction (qRT-PCR). Proliferation and apoptosis of N2a cells were detected after transfection of overexpression plasmid or siRNA SETD5-AS1. The downstream gene of SETP5-AS1 was predicted by Starbase and PTEN was screened out. Both mRNA and protein expressions of PTEN in MCAO model and OGD/R model were detected. Furthermore, the binding condition of SETD5 AS1 and PTEN was verified by dual-luciferase reporter gene assay, RNA pull-down assay and RNA binding protein immunoprecipitation (RIP). The regulatory effect of SETD5-AS1 on PI3K/AKT pathway was detected by Western blot. RESULTS: SETD5-AS1 was highly expressed in the ischemia-reperfusion injury model. Overexpression of SETD5-AS1 in N2a cells resulted in increased apoptosis and decreased proliferation. PTEN expression was upregulated in MCAO model and OGD/R model. Dual-luciferase reporter gene assay indicated that SETD5-AS1 can promote PTEN transcription. The binding condition of SETD5-AS1 and PTEN was further verified by RNA pull-down assay and RIP. Overexpression of SETD5-AS1 in N2a cells inhibited PI3K/AKT pathway. CONCLUSIONS: SETD5-AS1 is highly expressed in the ischemia-reperfusion injury model. SETD5-AS1 participates in the development of ischemic stroke by activating PTEN and inhibiting PI3K/AKT pathway. PMID- 30280789 TI - Effects of IL-1beta on hippocampus cell apoptosis and learning ability of vascular dementia rats. AB - OBJECTIVE: Vascular dementia (VD) is a type of memory, cognition, and behavior disorder caused by ischemic stroke or hemorrhagic stroke. It is a common pathogenesis of dementia that is only second to Alzheimer's disease. Inflammation plays a key role in VD. Interleukin-1beta (IL-1beta) is a kind of pro inflammatory cytokine, while its mechanism in VD occurrence and development is still unclear. MATERIALS AND METHODS: The healthy male rats were randomly divided into three groups, including sham group, VD model group (established by bilateral common carotid artery ligation), and IL-1beta group (treated by IL-1beta monoclonal antibody intracerebroventricular injection on based on model group). Rat learning ability was evaluated by Morris water maze assay. IL-1beta expression in brain tissue and peripheral blood was examined by using Real Time PCR and enzyme-linked immunosorbent assay (ELISA), respectively. Hippocampus apoptosis was detected by caspase 3 activity detection kit. B-cell lymphoma-2 (Bcl-2) and p38 mitogen-activated protein kinase (MAPK) protein levels were assessed by Western blot assay. RESULTS: IL-1beta expression was increased, caspase 3 activity was enhanced, Bcl-2 level was declined, and p-P38 phosphorylation was elevated in brain tissue and peripheral blood from VD model group compared to sham group (p<0.05). IL-1beta monoclonal antibody significantly reduced IL-1beta expression, improved learning ability, attenuated caspase 3 activity, increased Bcl-2 level, and declined p-P38 expression in VD rats compared to model group (p<0.05). CONCLUSIONS: IL-1beta can delay VD occurrence and development through the P38-MAPK signaling pathway to regulate cell apoptosis and improve learning ability.

AB - OBJECTIVE: To evaluate pathological lesions in New Zealand white rabbits with acute kidney injury (AKI) of septic shock and to explore the potential role of poly (ADP-ribose) polymerase (PARP) in regulating AKI development. MATERIALS AND METHODS: Endotoxic shock model in New Zealand white rabbits was first constructed. CVP (central venous pressure) was maintained at the baseline level by the saline administration. Rabbits were randomly assigned into sham group, LPS group, and LPS+3-AB group, respectively. Blood samples and kidney samples of rabbits were collected 4 h after LPS administration. Pathological kidney lesions were observed by HE (hematoxylin-eosin) staining and immunohistochemistry. Serum levels of renal damage markers (Scr, Cys-C, KIM-1, and NGAL) were detected by an automatic biochemical analyzer, immunoturbidimetry, and ELISA (enzyme-linked immunosorbent assay), respectively. Kidney energy metabolism changes (ATP, ADP, PCr, and NAD) were detected by HPLC (high performance liquid chromatography analysis). Western blot was conducted to detect protein expressions of NF-kappaB (nuclear factor-kappa B), TNF-alpha (tumor necrosis factor-alpha), ICAM-1 (intercellular cell adhesion molecule-1) and P-selectin in kidney tissues. RESULTS: Significant pathological lesions in kidney tissues and higher pathological grade were seen in the LPS group. Multiple PARP-positive nuclei were found in renal tubular cells at the junction of renal cortex and renal cortex in the LPS group. Serum levels of Scr, KIM-1, NGAL, and Cys-C were remarkably higher in the LPS group than those of sham group. HPLC results showed decreased levels of ATP, ADP, PCr, and NAD in kidney cortex of LPS group compared with those of sham group. Western blot results suggested that protein expressions of NF-kappaB, TNF-alpha, ICAM-1, and P-selectin were remarkably upregulated in kidney tissues of LPS group. 3-AB pretreatment, the PARP inhibitor, remarkably alleviated pathological lesions and inflammation induced by AKI. CONCLUSIONS: Inhibition of PARP overactivation alleviated pathological kidney lesions, improved kidney energy metabolism and inhibited inflammatory response resulted from AKI. PMID- 30280791 TI - IgG cryoglobulinemia. AB - OBJECTIVE: Mixed Cryoglobulinemia is the most well-known Hepatitis C Virus (HCV) associated extrahepatic manifestation. MC is both an autoimmune and B lymphoproliferative disorder. Cryoglobulins (CGs) are classified into three groups according to immunoglobulin (Ig) composition: type I is composed of one isotype or Ig class. Type II and type III mixed CGs are immune complexes composed of polyclonal IgGs acting as autoantigens and mono, polyclonal or oligoclonal IgM with rheumatoid factor activity. IgG1 and IgG3 are the predominant subclasses involved. This study shows the simultaneous presence of IgG-RF and IgG3, supporting the hypothesis of an involvement of this subclass in the initiation of early stages of CGs. PATIENTS AND METHODS: We describe a case series of six HCV positive patients, all of whom had peripheral neuropathy and transient ischemic attacks, presenting cryoprecipitates formed by IgG3 and IgG1. Cryoprecipitate IgG subclass research was carried out by immunofixation electrophoresis by using antisera against IgG1, IgG2, IgG3, and IgG4. RESULTS: Our six patients presented with an immunochemical pattern characterized by the mere presence of IgG1 and IgG3 subclasses with probable RF activity and one of these six patients exhibited monoclonal IgG3 in his cerebrospinal fluid. CONCLUSIONS: We can hypothesize that the IgG passage through the blood-brain barrier could have contributed to the cause of TIAs, through a mechanism involving the precipitation of circulating immune complexes formed by the two subclasses in the intrathecal vessels. PMID- 30280792 TI - Multilocus sequence typing for Candida albicans strains from the intestinal tract of patients with cirrhosis. AB - OBJECTIVE: Multilocus sequence typing (MLST) was applied to investigate the genetic diversity of Candida albicans in the intestinal tract of cirrhosis patients. PATIENTS AND METHODS: We used CHROM agar Candida medium to obtain 105 Candida sp. isolates from fecal samples (276 subjects), including 63 isolates from the cirrhosis group (141 subjects) and 42 isolates from the healthy control group (135 subjects). RESULTS: Among the 105 Candida strains isolated, 60 strains were identified as Candida albicans. Patients with cirrhosis had significantly higher rates of colonization by Candida sp. (44.68% vs. 31.11%, p < 0.05) and C. albicans (27.66% vs. 15.56%, p < 0.05) relative to healthy controls. In the cirrhosis group, the rate of colonization further increased with disease progression and antibiotic treatment (p < 0.01). Sixty C. albicans isolates were analyzed by MLST. Fifty diploid sequence types (DST) were observed, and 26 new DSTs and 3 novel alleles were found. The majority of isolates were distributed among three clades, clade 8 (31.67%), clade 14 (15.00%) and clade 18 (21.67%). Among 39 strains from the cirrhosis group, 16 strains (41.02%) belonged to clade 8, while only 3 strains (14.29%) from healthy group belonged to clade 8 (p < 0.05). In addition, concatenated sequences of the 7 housekeeping gene fragments were analyzed for all the different DSTs in clade 8 to evaluate the loss of heterozygosity (LOH), which indicates C. albicans microvariation in the gut of cirrhosis patients. CONCLUSIONS: This study suggests that cirrhosis disease progression and antibiotic treatment is associated with increased colonization by Candida sp. and C. albicans. We are the first to provide MLST-based genotype profiles for C. albicans Guizhou China, and to identify clade 8 as the potential main clade of C. albicans colonization in the gut of cirrhosis patients. PMID- 30280793 TI - An analysis of the iatrogenic biliary injury after robotic cholecystectomy. Current data and future considerations. AB - OBJECTIVE: Minimally invasive techniques are the gold standard in surgery. Since conventional laparoscopic approach has been widely adopted, surgeons in their effort to further improve their skills passed to the era of the robotic assistance. The widespread adoption of robotics has led to the inevitable usage of robotic technology both in simple, as well as in more complicated procedures. Cholecystectomy is the "simple" surgical procedure to which every surgeon from the beginning of his career and besides specialization or subspecialization is exposed to, but the ran complications have a dramatic impact both for patient and doctor. The elimination of bile duct injury is crucial and robotics in the new era of surgery has to be the gold standard to a safe cholecystectomy. MATERIALS AND METHODS: A comprehensive search of PubMed Database was conducted for English language studies using the MeSH terms [Robotic cholecystectomy, bile duct injury]. We reviewed references of all reports for additional cases from 2000 to nowadays. We used the related articles link and searched the citations of reports in the ISI Science Citation Index to identify additional reports. RESULTS: A total of 16 studies, including 2.264 patients that underwent robotic cholecystectomy were analyzed. Postoperative data and complications were collected from these studies. Bile duct injuries were more likely to be discovered during the first postoperative days as a bile leakage (8/2.264). One major bile duct injury was noticed, and most injuries were definitively treated at the hospital where the injury occurred with postoperative endoscopic retrograde cholangiopancreatography (ERCP) and stenting. CONCLUSIONS: Robotic cholecystectomy is a safe and adequate alternative to conventional laparoscopic or open approach in term of safety. Furthermore, surgeons must be already experienced and familiar with robotic techniques, so as to overcome the problem of the bile duct injury. PMID- 30280794 TI - HIF-1alpha promotes inflammatory response of chronic obstructive pulmonary disease by activating EGFR/PI3K/AKT pathway. AB - OBJECTIVE: Chronic obstructive pulmonary disease (COPD) is an incomplete, reversible disease with progressive inflammation obstruction in airways. This study aims to explore the regulatory mechanism of hypoxia-inducible factor-1alpha (HIF-1alpha) in inflammatory response and progression of COPD. PATIENTS AND METHODS: 71 bronchoalveolar lavage fluid (BALF) samples were collected, including 59 samples from COPD patients (COPD group) and 12 from patients with normal pulmonary function (control group). The mRNA and protein levels of HIF-1alpha and epidermal growth factor receptor (EGFR) in BALF were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) and Western blot, respectively. Serum levels of interleukin-13 (IL-13), IL-9, IL-1, and tumor necrosis factor alpha (TNF-alpha) were detected by enzyme-linked immunosorbent assay (ELISA). Hypoxia cell model was constructed by COCl2 induction in human embryonic lung cells. Expression levels of HIF-1alpha, EGFR and p-AKT in NCI-H1563 cells treated with 740Y-P, the phosphoinositide 3-kinase (PI3K) agonist were detected. Finally, we detected proliferation and apoptosis in NCI-H1563 cells with HIF-1alpha overexpression by cell counting kit-8 (CCK-8) assay and flow cytometry, respectively. RESULTS: The mRNA and protein levels of HIF-1alpha and EGFR were higher in COPD groups compared with those of control group. Serum levels of IL 13, IL-9, IL-1, and TNF-alpha in COPD patients were elevated. CoCl2 induction in NCI-H1563 cells led to upregulated levels of IL-13, IL-9, IL-1, and TNF-alpha. 740Y-P treatment remarkably activated EGFR/PI3K/AKT pathway. Overexpressed HIF 1alpha inhibited proliferation but induced apoptosis of NCI-H1563 cells. CONCLUSIONS: HIF-1alpha was overexpressed in COPD, which upregulated expressions of inflammatory factors via activating the EGFR/PI3K/AKT pathway. The activated EGFR/PI3K/AKT pathway induced by pulmonary inflammation further upregulated HIF 1alpha expression in a feedback loop, thus aggravating COPD pathological changes. PMID- 30280796 TI - The mechanisms of Ang II-induced hypertensive vascular remodeling under suppression of CD68 in macrophages. AB - OBJECTIVE: High blood pressure (hypertension) is one of the most common cardiovascular diseases. In recent years, there were more and more studies on the function of inflammation in hypertension. CD68 mainly mediates the activation of cytokine interleukin-17 (IL-17) signaling pathway and participates in inflammatory responses. It has been studied the function of CD68 and IL-17 in hypertension, but it has not been reported whether it affected hypertension and vascular remodeling when macrophage CD68 expression inhibited. In this study, antisense-CD68 mice were used to study the effect and mechanism of angiotensin II induced hypertensive vascular remodeling under specific suppression of macrophage CD68. MATERIALS AND METHODS: Fifty 8-week-old male antisense-CD681 and C57 mice were divided into control and experimental group (angiotensin II group, 1000 ng*kg-1*min-1). After infusion of angiotensin II for 28 days, hematoxylin-eosin (HE) staining and immunohistochemical staining were used to observe the remodel of vascular. The changes of aortic inflammatory factors were detected by Real time PCR (RT-PCR) and Western blotting. RESULTS: By specifically inhibiting the expression of macrophage CD68, macrophage infiltration was mitigated in Ang II induced hypertensive vascular remodeling model mouse, which also down-regulated the expression of vascular tissue inflammatory factor and activation of vascular smooth muscle cell p65. CONCLUSIONS: CD68 regulates the Ang II-induced hypertensive vascular remodeling through mediating macrophage inflammatory factor release. PMID- 30280795 TI - IL-10 promotes development of acute respiratory distress syndrome via inhibiting differentiation of bone marrow stem cells to alveolar type 2 epithelial cells. AB - OBJECTIVE: To explore whether interleukin-10 (IL-10) could promote the development of acute respiratory distress syndrome (ARDS) via inhibiting differentiation of bone marrow stem cells (BMSCs) to alveolar type 2 (AT II) epithelial cells. PATIENTS AND METHODS: 25 ARDS (acute respiratory distress syndrome) patients admitted in our hospital from December 2015 to February 2018 were enrolled. Meanwhile, 25 healthy controls in the same period were selected as control group. Serum level of IL-10 in each subject was detected via ELISA (enzyme-linked immunosorbent assay). BMSCs were isolated and cultured, followed by identification of surface antigens and morphology observation using flow cytometry. For in vitro experiments, expression levels of AT II-related genes induced with or without IL-10 were detected by qRT-PCR (quantitative Real-time polymerase chain reaction) and Western blot, respectively. The culture medium of BMSCs induced with or without IL-10 was collected for detecting expression levels of interleukin-1 (IL-1), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) by ELISA. RESULTS: IL-10 was overexpressed in ARDS patients than that of healthy controls. Primary BMSCs were elongated after culturing for 1-3 days. Negative-antigen CD34 (4.32%) and positive-antigen (99.87%) on the surface of BMSCs were identified by flow cytometry. Both mRNA and protein expressions of AT II-related genes increased in a time-dependent manner. ELISA results showed that IL-10 level in cell supernatant decreased with the prolongation of induction days. Moreover, IL-10 intervention downregulated the expressions of AT II-related genes. CONCLUSIONS: IL-10 promotes ARDS development via inhibiting cell differentiation of BMSCs to AT II. PMID- 30280797 TI - Correlation between adiponectin polymorphism and atherosclerotic plaque compositions under intravascular ultrasound (IVUS). AB - OBJECTIVE: To discuss the correlation between polymorphism of rs266729 ( 11377C/G, Cytosine/Guanine) (adiponectin promoter) site and atherosclerotic plaque compositions as well as related indicators under intravascular ultrasound (IVUS). PATIENTS AND METHODS: 76 patients with coronary heart disease from December 2014 to December 2016 were enrolled. The PCR-RFLP method was used to analyze the adiponectin gene polymorphism in rs266729 site. All the objects were divided into CC type group (n=26), CG type group (n=23), and GG type group (n=27) according to the results of polymorphism. The amount of lesions and length of lesion in the vessel were determined according to the images of coronary angiography. The indicators from each group, including minimum external elastic membrane area, the smallest lumen area, the patch area, the patch load, the lipid pool area, the lipid pool/plaque area, the fiber cap thickness, the reconstruction index, the positive reconstruction, the negative reconstruction and the patch character were measured according to the IVUS results. RESULTS: The baseline data from distinct the gene types showed no significant difference. The results of quantitative IVUS plaque analysis indicated a statistical difference of factors such as plaque area, plaque burden, lipid pool area, lipid pool/plaque area, and remodeling index between the CC and GG types (p<0.05). The levels of aminopeptidase N (APN), tumor necrosis factor alpha (TNF-alpha), interleukin 1 beta (IL-1beta), fasting serum insulin (FIN), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) among diverse groups presented statistical difference (p<0.05). Of note, the analysis results of IVUS qualitative components of plaque showed that soft plaque in CC group was 42.3% (11/26), which was significantly lower than GG group 11.1% (3/27) (p<0.05). The vascular remodeling ratio in CC group 26.9% (7/26) was also significantly decreased compared to that in GG group 66.7% (18/27) (p<0.05). The tubular and diffuse ratio in CC groups according to the comparison of diseased vessel, count, length of the lesion were 34.6% (9/26) and 42.3% (11/26), respectively. CONCLUSIONS: Our data on biochemical indicators demonstrates CC type gives rise to poor prognosis compared to GG type does, which suggests that close attention should be paid in the impact of adiponectin polymorphism on atherosclerotic plaque compositions. PMID- 30280798 TI - Down-regulation of miR-192 protects against rat ischemia-reperfusion injury after myocardial infarction. AB - OBJECTIVE: DJ-1-phosphate and tension homology deleted on chromosome ten/phosphatidylinositol-3-kinase/protein kinase B (PTEN/PI3K/AKT) signaling pathway plays a role in the regulation of ischemic reperfusion (I-R) injury. Bioinformatics analysis demonstrated that there is a complementary binding site between microRNA-192 (miR-192) and the 3'-UTR of DJ-1 mRNA. This study investigated the role of miR-192 in regulating DJ-1-PTEN/PI3K/AKT signaling pathway and myocardial I-R injury. MATERIALS AND METHODS: miR-122 and DJ-1 mRNA expressions in myocardial tissue were detected by Real-time PCR (RT-PCR). DJ-1, PTEN, and phosphorylated AKT (p-AKT) protein expressions were tested by Western blot. Reactive oxygen species (ROS) content was measured by flow cytometry. Malondialdehyde (MDA) content and superoxide dismutase (SOD) enzyme activity were detected by the kits. I-R treatment was performed at 72 h after transfection. Cell apoptosis was evaluated with flow cytometry. RESULTS: Compared with sham group, miR-192, PTEN expressions and MDA content were significantly increased (p<0.05), while DJ-1, p-AKT levels and SOD activities were significantly reduced (p<0.05) in myocardial tissue of I-R group. Compared with control, I-R treatment significantly up-regulated miR-192 level, significantly decreased DJ-1 and p-AKT proteins, significantly elevated PTEN expression, and significantly induced apoptosis and ROS production in H9C2 cells (p<0.05). Transfection of miR-192 inhibitor significantly enhanced DJ-1 level, declined PTEN expression, elevated p AKT level, and restrained apoptosis, ROS production and MDA content, and promoted SOD activity in H9C2 cells under I-R condition. CONCLUSIONS: The expression of miR-192 increased significantly, while the expression of DJ-1 reduced obviously during I-R injury after myocardial infarction. Down-regulation of miR-192 markedly enhanced DJ-1 expression and PTEN/PI3K/AKT pathway activity, inhibited cell apoptosis and ROS generation, and reduced I-R injury in cardiomyocytes. PMID- 30280799 TI - MiR-223 promotes cardiomyocyte apoptosis by inhibiting Foxo3a expression. AB - OBJECTIVE: MicroRNAs (miRs) are proven to possess diversified functions in the pathogenesis of cardiac diseases. The current study is designed aiming at determining the effect of miR-223 on oxidative stress induced apoptosis in cardiomyocytes. MATERIALS AND METHODS: Mouse model of myocardial infarction (MI) was constructed, and endogenous level of miR-223 in the border zone of infarcted heart tissues was determined. Primarily cultured cardiomyocytes were exposed to H2O2 treatment to mimic the oxidative stress stimulation. Multiple approaches including quantitative reverse transcription polymerase chain reaction (qRT-PCR), cell viability assay, luciferase assay, Western blot assay and flow cytometry assay were employed to determine its expression, function and mechanism in apoptosis. RESULTS: MiR-223 expression was significantly upregulated in the border zone of infarcted heart ventricular tissues and in cardiomyocytes treated with H2O2. Overexpression of miR-223 in cardiomyocytes promoted apoptosis, whereas inhibition of endogenous miR-223 protected cardiomyocytes from oxidative stress induced apoptosis. MiR-223 directly targets the 3'untranslated region (UTR) of Foxo3a mRNA. Overexpression of miR-223 inhibited Foxo3a protein expression, however, inhibition of miR-223 suppressed its expression. Silencing Foxo3a using small interfering RNA (siRNA) mimicked the effect of miR-223, indicating its functional significance. CONCLUSIONS: MiR-223 is an important regulator of cardiomyocyte apoptosis under oxidative stress. Inhibition of the miR-223/Foxo3a signaling axis may be a potential therapeutic strategy for cardiac injuries. PMID- 30280800 TI - Using intra-articular tranexamic acid in total knee replacement surgery with and without bleeding control: a prospective randomized double blind study. AB - OBJECTIVE: To investigate the effectiveness of tranexamic acid (TA) application in two techniques: in the first one wound closure is performed before the tourniquet is released; in the second one, wound closure is performed after the tourniquet is released. PATIENTS AND METHODS: The study is conducted on four groups of patients: (1) TA + TNR (tourniquet not released) where there is no bleeding control and TA is applied after wound closure without tourniquet release; (2) TA - TNR where placebo is applied after wound closure without tourniquet release; (3) TA + TR (tourniquet released) where tourniquet is released first and TA is applied after bleeding control and wound closure; and (4) TA - TR where tourniquet release is followed by bleeding control and placebo application. RESULTS: The amount of hemorrhage in hemovac drains in each group was as follows: 217.4 +/- 99.6 (100-590) ml in the TA + TNR group; 411.6 +/- 133.7 (175-850) ml in the TA - TNR group; 291.2 +/- 89.5 (160-650) ml in the TA + TR group; and 458.2 +/- 138.6 (200-920) ml in the TA - TR group (p<0.0001). The TA + TNR group differed significantly from other groups in terms of the hemorrhage in drains. Similarly, the TA + TNR group was notably different from the TA - TNR and TA - TR groups with regard to the hemoglobin and hematocrit values. CONCLUSIONS: The study reveals that the amount of blood in hemovac drains is reduced significantly after the application of tranexamic acid to the suprapatellar space in the technique where wound closure is performed without bleeding control and before the tourniquet is released. PMID- 30280801 TI - Diazoxide induces endoplasmic reticulum stress-related neuroprotection mediated by p38 MAPK against Abeta25-35 insults. AB - OBJECTIVE: The endoplasmic reticulum (ER) -resident caspase-12 was identified as a mediator of Abeta neurotoxicity. Recent evidence indicates that mitochondrial ATP-sensitive potassium (KATP) channel openers mediate their neuroprotective role by adjusting ER stress pathways, but the molecular details remain largely unknown and have been investigated. MATERIALS AND METHODS: In this study, the protein expression levels of calreticulin (CRT) and caspase-12 activation and phosphorylated p38 MAPK were observed by immunoblotting in cultured PC12 cells from different groups: treatment with Abeta25-35 (group Abeta25-35), treatment with diazoxide (group diazoxide), pretreatment with diazoxide and then exposure to Abeta25-35 (group diazoxide + Abeta25-35), pretreatment with p38 MAPK inhibitor SB 203580 and then exposure to diazoxide and Abeta25-35 (group SB 203580 + diazoxide + Abeta25-35), and the control (group control). RESULTS: In response to the treatment with Abeta25-35 (10 uM) for 24 h, the protein expression levels of CRT and caspase-12 activation were increased and phosphorylated p38 MAPK was decreased significantly. Diazoxide reduced CRT overexpression and caspase-12 activation and increased the up-regulation of phosphorylated p38 MAPK. When SB 203580 was presented before exposure to diazoxide and Abeta25-35, CRT expression was markedly suppressed, and the inhibition effect of diazoxide on caspase-12 activation was almost eliminated. CONCLUSIONS: We showed that diazoxide induced ERS-related neuroprotection mediated by p38 MAPK against Abeta25-35 insults. From the clinical point of view, these results are of considerable importance for the understanding of AD pathogenesis. However, further studies are required to explore more detailed mechanisms of the observed effects. PMID- 30280802 TI - Octreotide protects doxorubicin-induced cardiac toxicity via regulating oxidative stress. AB - OBJECTIVE: To explore the role of octreotide in doxorubicin-induced (DOX) cardiac toxicity in rats, and to investigate its underlying mechanism. MATERIALS AND METHODS: A total of 24 male Sprague Dawley (SD) rats were randomly assigned into 3 groups, including: the control group (NS group), the DOX-induced cardiac toxicity group (DOX group) and the OCT pretreatment + DOX-induced cardiac toxicity group (OCT group). Each group had 8 experimental SD rats. Electrocardiogram was performed in each rat before and after animal procedure, respectively. The serum and heart samples of each rat were collected 10 days after the surgical procedure. Cardiomyocyte apoptosis in the myocardial ischemic area of rats was determined by hematoxylin and eosin (HE) staining and Terminal Deoxynucleotidyl Transferase dUTP Nick-end Labeling (TUNEL) staining. DOX-induced oxidative stress was evaluated by detecting the activities of SOD (superoxide dismutase), MDA (malondialdehyde), GSH (glutathione), T-AOC (total antioxidant capacity) and CAT (catalase). The expression levels of nuclear factor E2 related factor-2 (Nrf2), heme oxygenase-1 (HO-1) and quinone oxidoreductase 1 (NQO1) were detected by Western blot and immunohistochemistry. RESULTS: Compared with the NS group, heart rate and voltage of QRS wave were both significantly reduced in the DOX group, whereas Q-T interval was significantly prolonged (p < 0.05). Arrhythmia was even found in some rats of the DOX group. However, rats in the OCT group had significantly higher heart rate and voltage of QRS wave, as well as shorter Q-T interval when compared with those of the DOX group (p < 0.05). The levels of plasma CK-MB and LDH were remarkably lower in the OCT group than those of the DOX group. The activities of SOD, GSH, CAT and T-AOC in cardiac homogenate of the OCT group were higher than those of the DOX group. However, MDA activity and ROS level in cardiac homogenate were remarkably reduced in the OCT group when compared with those of the DOX group (p < 0.05). Cardiac pathological lesions were alleviated by OCT pretreatment. Moreover, the expression levels of Nrf2, HO 1 and NQO1 were significantly upregulated in the OCT group than those of the DOX group. CONCLUSIONS: Octreotide improves the anti-oxidant capacity of cardiomyocytes via activating the Nrf2 pathway, thereby protecting doxorubicin induced cardiac toxicity in rats. PMID- 30280803 TI - Protective effect of simvastatin on arterial plaque instability induced by p cresyl sulfate. AB - OBJECTIVE: To study the protective effect of simvastatin on arterial plaque instability induced by p-cresyl sulfate (PCS). MATERIALS AND METHODS: Apolipoprotein E (ApoE)-/- mice were selected as objects of this study. All mice were randomly divided into three groups: 1) the control group, 2) the PCS group and 3) the PCS + simvastatin group. After successful modeling, the levels of plasma cholesterol, triglyceride, low-density lipoprotein, high-density lipoprotein, interleukin-1 (IL-1), interleukin-6 (IL-6) and tumor necrosis factor beta (TNF-beta) were detected. The gross specimen of coronary artery was stained. Meanwhile, oil red O staining and Sirius red staining were performed for coronary arterial sections to observe the lipid and collagen components. The expression levels of smooth muscle cells and macrophages were observed by immunohistochemistry. In addition, the expression levels of matrix metalloproteinases (MMPs), tissue inhibitors of metalloproteinases (TIMPs) and monocyte chemoattractant protein-1 (MCP-1) in tissues were detected by Western blotting. RESULTS: Simvastatin could improve atherosclerotic plaque growth and atherosclerotic plaque instability induced by PCS. Moreover, simvastatin could also improve the changes of MMPs and TIMPs caused by PCS as well as the inflammatory status in mice. CONCLUSIONS: Simvastatin can improve the inflammatory status in mice, eventually improving the arterial plaque instability caused by PCS. PMID- 30280804 TI - Experimental study on application of polypropylene hernia of fat stem cells in rats. AB - OBJECTIVE: An inguinal hernia is the most common type of external abdominal hernia. Normal surgery utilized polypropylene mesh to fix a hernia, but often leads to adverse effects including pain and foreign body sensation. Adipose derived stem cells are pluripotent stem cells that can be differentiated into adipocytes, chondrocytes, skeletal myoblast and osteoblast. The compatibility of stem cells with absorbent material mesh or cellular biology mesh has been studied. This study investigated the application of adipose-derived stem cells coated polypropylene mesh in treating an inguinal hernia. MATERIALS AND METHODS: Adipose-derived stem cells were separated and cultured from adipose tissues of SD rats. Flow cytometry was utilized to determine antigen subtype including CD90, CD34, CD44, and CD45 on the cell surface. Those cells were then induced to be differentiated into adipocytes, osteocytes and chondrocytes. Adipose-derived stem cells coated polypropylene mesh was then prepared and implanted under a muscular layer of rat peritoneal cavity. The occurrence of hematoma and routine blood indexes were examined. RESULTS: Adipose-derived stem cells showed attached growth with satisfactory proliferation ability. Flow cytometry results showed positive rates for CD90, CD44, CD34, and CD45 at 98.2% +/- 1.4%, 97.6% +/- 2.3%, 54.3% +/- 6.3%, and 13.4% +/- 4.2%, respectively. Adipose-derived stem cells had the potency of differentiation. The application of novel mesh decreased macrophage number and lymphocytes (p < 0.01) but not leukocytes or neutrophils (p > 0.05). CONCLUSIONS: Adipose-derived stem cells coated polypropylene mesh can decrease the inflammation post inguinal hernia and can be used as one novel biomaterial in treating an inguinal hernia. PMID- 30280805 TI - Efficacy of romiplostim in the treatment of ITP in children: a meta-analysis. AB - OBJECTIVE: We aimed to analyze the efficacy and safety of romiplostim in the treatment of primary immune thrombocytopenia (ITP) in children. MATERIALS AND METHODS: PubMed, the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, Chinese biomedical literature database (CBM), Chinese Journal Full Text Database (CNKI), Wanfang and VIP database were searched. The bibliography was screened according to the inclusion and exclusion criteria and the target literature was selected. The data were extracted, and the quality of included literature was evaluated. RevMan 5.3 software was used to carry out the meta-analysis. The rate of effective, adverse and bleeding events was collected, and meta-analysis was performed. RESULTS: 3 out of 43 papers met the inclusion criteria. Meta-analysis showed that there was a statistical significance in effective rate and median time to platelet rise to response criteria of in romiplostim group, RR=5.05, [95% CI (2.21, 11.53), p<0.01] and RR=9.67, [95% CI (1.89, 49.46), p<0.01]. Similar results occurred in the rate of adverse event and serious adverse event, [RR=0.95, 95% CI (0.69,1.31), p>0.05] and [RR=1.65, 95% CI (0.53,5.31), p>0.05]; bleeding event of the two groups was similar [RR=1.27, 95% CI (0.92,1.75), p>0.05]. CONCLUSIONS: On the aspect of treating ITP, romiplostim is more effective and safer than placebo.

PMID- 30280807 TI - FGF23 promotes renal interstitial fibrosis by activating beta-catenin. PMID- 30280808 TI - [Spectral Study of LaCl3 in Aqueous Solutions]. AB - In this study, the Raman and fluorescence spectra of LaCl3 solution were studied with theoretical calculation and spectroscopic experiments. Based on B3LYP method of density functional theory, with the 6-31G(D,P)+Def2-SV (P) based on the group level the lanthanum chloride solution of micro cluster structure is calculated. The results show that the micro cluster molecules tend to form a 9 coordination structure, which verifies the feasibility of the method. Theoretical and experimental Raman values are compared to the basic consistent. The addition of LaCl(3) leads to the increase of the peak intensity of the Raman spectra in the 300~600 cm-1 range, which may be caused by the superposition of the La-O vibration and the rocking peaks of O-H in aqueous solutions; In the 3 000~4 000 cm(-1) range, the peak of lanthanum chloride solution is narrow compared with water, which may be caused by the stretching vibration of O-H in lanthanum hydrate. Fluorescence emission spectra at 350 nm appear obvious new peak, the good linearity was obtained between the peak intensity and the concentrations, and a rapid method for the quantitative analysis of lanthanum chloride solution from the angle of the complex is also realized. On the same basis set level calculated fluorescence emission center of clusters, in the range of allowable error, the theoretical calculation and the experimental spectra are basically consistent, and the new peak of the experimental spectra are identified.

AB - Aim: The aim of the present study was to show different aspects of the interrelation between pathology of the gastrointestinal tract and rheumatic diseases based on literature rewiev, single-centers data and case reports. Materials and methods: First literature review was performed (databases PubMed, Medline). Then was analyzed information according presence of gastrointestinal disease in 126 patients with axial spondyloarthritis (SpA) and collected case reports as illustration the problem. Results: Involvement of the gastrointestinal tract in rheumatic diseases in general is characterized by clinical, etiologycal and pathogenetic heterogeneity. It was found a few typical combinations: the defeat of the digestive tract as one of the clinical manifestations of rheumatic disease (hemorrhagic vasculitis, etc.); the defeat of the digestive tract and rheumatic disease as equal related conditions (Crohn's disease and ankylosing spondylitis); the defeat of the digestive tract as a consequence of long-existing inflammation (amyloidosis, esophagus Barrett); gastrointestinal tract involvement as complication of treatment of the rheumatic disease (bleeding when using nonsteroidal anti-inflammatory drugs); rheumatic disease as a manifestation of paraneoplastic syndrome of the digestive tract. The presence of diseases of the gastrointestinal tract is established in more than half (58%) patients with axial SpA. In the group of patients considered the most frequently met gastritis (15%), chronic pancreatitis (15.9%) and chronic cholecystitis (19%). Conclusions: Gastrointestinal tract occurs no less than half of the patients with rheumatic diseases and may be either primary or secondary to systemic disease. The possibility of coexistence of diseases of the gastrointestinal tract and rheumatic disease must be taken into account in the course of patient care. In some cases, treatment should be carried out together - a gastroenterologist and a rheumatologist.

AB - Most infectious diseases are caused by pathogenic infiltrations from the mucosal tract. Nowadays, the use of vaccines has been widely investigated for the prevention of different infectious diseases, infertility, immune disorders, malignancies, and allergies. Broad-spectrum adjuvant substances have been studied for immune system stimulation with a greater efficiency against specific antigens. Various adjuvants have been developed such as inorganic, oil-based, and emulsion adjuvants, bacterial products and their derivatives, cytokines, cytosine guanine dinucleotide (CpG) motifs, and particulate systems. Mucosal vaccine delivery is an alternative route to induce both humoral and cellular immune responses. Applying nanoparticles in vaccine formulations allows not only improved antigen stability and immunogenicity, but also targeted delivery, and consequently, more specific release of the agent of interest. Chitosan nanoparticles have immunological activity and mucoadhesive properties. They have been used as a mucosal vaccine delivery system for many antigens. This review provides an overview of the recent advances in chitosan nanoparticles as a novel mucosal vaccine delivery system. PMID- 30280837 TI - Development and Evaluation of Real-Time RT-PCR Test for Quantitative and Qualitative Recognition of Current H9N2 Subtype Avian Influenza Viruses in Iran. AB - Avian influenza H9N2 subtype viruses have had a great impact on Iranian industrial poultry production economy since introduction in the country. To approach Rapid and precise identification of this viruses as control measures in poultry industry, a real time probe base assay was developed to directly detect a specific influenza virus of H9N2 subtype -instead of general detection of Influenza A viruses- which has been endemic over two last decades in the country. An Iranian avian influenza virus strain of A/Iran/chicken/772/1998 H9N2 subtype were selected as reference strain for of primers and probe designing. The high agreement value of 99% indicated that the devolved real time assay for detection of H9 subtype viruses could easily replace the conventional method of virus isolation particularly in investigation of viruses like national surveillance plan. The limit of detection was almost one EID50 which was the least real infectious unit could be detected. So it can be said that this sensitive assay provided a powerful tool to not to miss any significant viral biological activity neither in the host body nor in the environment. A high level of correlation coefficient (R2 = 0.998) also indicated a good correlation between Ct values and viral concentrations. , it can be conclude that the real time RT-PCR could be easily replace virus isolation in detection of H9N2 influenza viruses especially in large monitoring program. The ability in quantifying of the virus concentration extends usage of test in more accurate studies. PMID- 30280838 TI - Sequencing and In Silico Multi-aspect Analysis of S1 Glycoprotein in 793/B Serotype of Infectious Bronchitis Virus Isolated From Iran in 2003 and 2011. AB - Infectious bronchitis (IB) is an acute, highly contagious, and economically important viral disease of chickens. The S1 subunit from Spike (S) protein plays the major role in protective immunity and is involved in the host-virus interactions, as well as infectious bronchitis virus (IBV) serotyping. Aim of the present study was multi-aspect analysis of the molecular and immunological features of 5' part belonging to the S1 glycoprotein sequence of Iranian 793/B IBV strain isolates. This might ideally help in characterization, prevention, and vaccine development. The tissue samples were prepared, followed by virus isolation, reverse transcription polymerase chain reaction and restriction fragment length polymorphism analysis. In addition, sequencing and registration of the sequences in the National Center for Biotechnology Information were performed. Moreover, 12 sequences were retrieved from Fars province, Iran. The next steps included evaluation of conservation/variability along the sequences, phylogenetic analysis, estimation of the average evolutionary divergence over all the sequence pairs, predicting the phosphorylation/N-glycosylation/palmitoylation sites, and the final analysis of antigenicity. The findings of alignment, entropy plot, and pairwise similarity analysis revealed 17 hypervariable regions. The isolates belonging to Tehran were clustered in phylogenetic tree, and the most similar isolates to them were ADW11182 and ADW11183. Location of some of the N glycosylation/phosphorylation/palmitoylation points indicated that these sites were conserved among the isolates. Furthermore, the frequency of epitopes and their scores reflect the high immunogenicity of S1 protein in 793/B serotype. Analysis of the primary and secondary structures demonstrated that their parameters had variable values and were different regarding the number and location of α-helix, β-strand, and coils. According to our findings, the Iranian isolates of 793/B serotype change their molecular characteristics during time and in different geographical regions. These alterations might account for failure in prevention programs and differences in virulence and pathogenicity. PMID- 30280839 TI - Design and Production of a Novel Recombinant Chimeric IL2-Omp31 Antigen against Brucella Infection. AB - Brucellosis is a zoonotic disease in human and animals. Brucella melitensis is one of the most pathogenic species of Brucella in goat and sheep. Omp31 is an outer membrane protein of Brucella that acts as an immunogenic protein. Cytokines are glycoproteins with low molecular weight that play the role of an immune adjuvant and regulate immune responses. Interleukin-2 is one of the most important cytokines, which are secreted by the white blood cells and involved in T cell immune responses. In the present study, a chimeric Omp31-Interleukin2 recombinant protein was generated by means of genetic engineering techniques. This chimeric coding sequence was amplified by using specific primers and using Splicing Overlap Extension (SOE) PCR technique. The fusion of the two mentioned proteins was accomplished using a rigid linker. The generated chimeric IL2-Omp31 fragment was TA cloned, and then subcloned into pEt22b vector as an expression vector. The chimeric protein was successfully expressed in E. coli BL21 (DE3) and confirmed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and also Western-blotting analysis. Finally, in order to assess the antigenic features of the recombinant chimeric IL2-Opm31 protein, its secondary structure and antigenicity were predicted in silico. PMID- 30280841 TI - A Serological Survey of Neospora caninum Infection in Urban and Rural Dogs in Ahvaz District, Southwest of Iran. AB - Dogs are important in the epidemiology of Neospora caninum because they act as definitive hosts, shedding oocysts in the environment. The aim of the present survey was to evaluate the serological prevalence of Neospora caninum infection in urban and rural dogs in Ahvaz district, southwest of Iran. In this study, blood samples were taken from 100 rural dogs and 50 urban dogs. The dogs were categorized into two age groups (i.e., ≤ 3 and > 3 years). Neospora agglutination test (NAT) was performed for the detection of infection. Among 150 samples, 30 (20%) showed infection in 1:50 to 1:800 dilutions by NAT (confidence interval 95%: 13.60-26.40). The antibody titers were as follows: 1:50 (n=1), 1:100 (n=14), 1:200 (n=3), 1:400 (n=10) and 1:800 (n=2). The highest serum dilution was 1:100 in 46.67% of the infected dogs and the lowest serum dilution was 1:50 in 3.33% of them. The obtained results showed a significant difference in seroprevalence between urban (10%) and rural (25%) dogs (P=0.03). Although the seroprevalence was higher in dogs above three years of age (23.33%) than below three years (17.78%), there was not a significant difference among different age groups in this regard (P>0.05). The possibility of infection in dogs above the age of three years was 1.3 more than those below three years of age (confidence interval 95%: 0.58-2.9). It can be concluded that a relatively considerable percentage of dogs in Ahvaz district are infected with N. caninum. These infected dogs can play an important role in the transmission of neosporosis to other animals.

AB - The present study was conducted with the aim of comparing the effects of premedication with ketoprofen and midazolam in birds. A total of 24 male pigeons with an approximate weight of 300 g were divided into four equal groups. The control group (Group I) was injected with ketamine alone. Groups II-IV were injected with ketoprofen alone, ketoprofen+ketamine, and midazolam+ketamine, respectively. The biochemical changes in the four groups were evaluated after intramuscular drug injections at different anesthetic levels. A record of biochemical changes was maintained for each group. Blood samples were taken before and after the administration of the medications in order to measure the levels of serum alkaline phosphatase (ALP), oxaloacetate transaminase (OT), prothrombin time (PT), glucose (GLU), lactate dehydrogenase (LDH), albumin (Alb), total protein (TP), and gamma-glutamyl transferase (GGTF). The results showed significant differences in the mean levels of ALP, OT, PT, GLU, LDH, Alb, and TP after anesthesia, compared to that before anesthesia. Therefore, ketoprofen+ketamine can be used for the induction of anesthesia in birds.The present study was conducted with the aim of comparing the effects of premedication with ketoprofen and midazolam in birds.

PMID- 30280840 TI - Antimicrobial Susceptibility Profile of Enterococcus Species Isolated from Companion Birds and Poultry in the Northeast of Iran. AB - Enterococci are Gram-positive facultative anaerobic bacteria commonly found in the gastrointestinal tract of the mammals and birds. These cocci are isolated from urinary tract infections, bacteremia, endocarditis, and burn wounds in humans. The evolution of antibiotic-resistant enterococci raised a problem due to the possibility of the transmission of these organisms between poultry and human. Regarding this, the present study was conducted to evaluate the prevalence of Enterococcus species among companion birds and poultry in the Northeastern of Iran and determine the antibiotic susceptibility profile of enterococci. To this end, oral and cloacal swabs were collected from 150 caged birds. Antibiotic susceptibility profile was determined using the standard disk diffusion method. The results revealed that out of 150 samples, 56 (37.33%) cases contained enterococci. Most of the specimens (25.33%) were Enterococcus faecalis isolated from 6.66% of the samples. Additionally, 2.66% and 1.33% of the samples were contaminated with Enterococcus mundtii and Enterococcus gallinarum, respectively. Furthermore, Enterococcus malodoratus and Enterococcus raffinosus were isolated from 0.66% of the samples. The results revealed that all of the isolates of E. faecalis and E. faecium were resistant to more than five antimicrobial agents. Most of E. faecalis and E. faecium isolates showed resistance to Cefazolin, Tiamulin, Flumequine, and Cephalexin. Accordingly, the majority of the isolates had multidrug resistance to the tested antibiotics. In conclusion, the presence of multidrug-resistant enterococci in the birds living close to humans requires thorough observations due to the transmission of these organisms to humans. PMID- 30280843 TI - Bioinformatics Analysis of Upstream Region and Protein Structure of Fungal Phytase Gene. AB - Phytase increases the bioavailability of phytate phosphorus in seed-based animal feeds and reduces the phosphorus pollution of animal waste. Since most animal feeds for pellets are heated up to 65-80 °C, the production of a thermostable structure for phytase can be useful. In this study, we sought to perform bioinformatics analysis of the upstream region and protein structure of fungal phytase to improve its expression and thermostability properties. We used bioinformatics methods such as similarity search, multiple alignment, statistical analysis of physicochemical properties of amino acids, pattern recognition, and protein modeling to find out the effective factors in heat resistance of phytase. Change in Gibbs free energy (ΔG) of the best pattern promoter resulting from the interaction between RNA polymerase and the promoter sequences of modified genes of phytase was equal to -9 kcalmol-1, which is lower compared to other interactions. The evaluation of the three-dimensional structure of new phytases showed that amino acid substitutions aimed at improving thermostability did not change the form and structure of the protein. The results of Prochek, Whatcheck, and ERRAT for structural analysis and verification were 84, 72, and 70, respectively, that were satisfactory. PMID- 30280844 TI - Diagnosis of Avian Mycoplasmas: A Comparison between PCR and Culture Technique. AB - Mycoplasma gallisepticum and Mycoplasma synoviae are the causative agents of avian mycoplasmosis in commercial poultry. Among the available tools, polymerase chain reaction (PCR) and culture are confirmatory tools for the diagnosis of mycoplasmosis after the initial serological screening of suspected birds. Overall, 181 samples were analyzed, 152 (84%) and 103 (57%) of which were found positive by PCR and culture, respectively. Further, 54 (92%) broiler samples were found positive for general avian mycoplasma. Among the total positive samples, MS positivity was as high as 72 (47%) by PCR, while it was 45 (44%) by culture. MG positivity was 23% and 25% in PCR- and culture-positive samples. MG grows more easily compared to MS. The agreement value between the tests was 67%. Overall, flock wise prevalence was not much varied. The prevalence of mycoplasmosis was higher during winter. Our study confirmed that PCR is the most sensitive and reliable tool for the diagnosis of avian mycoplasmosis in field samples. PMID- 30280845 TI - [Efficient Polymer Solar Cells Using ZnO Electron Transporting Layer with Layered Magentron Sputtered ZnO Film and/or Modified with Functionalized Carbon Nanopartilces]. AB - Polymer solar cells (PSCs) with ZnO electron transporting layer has been widely studied because ZnO has superior electron transport capability and high light transmittivity. However, lots of defects existed in ZnO film fabricated with sol gel method and vacuum sputtering deposition can greatly increase carrier recombination at the ZnO interface. Therefore, it is important to enhance the performance of PSCs to inhibit defects and improve contact quality of ZnO interface. The regioregular poly(3-hexylthiophene) (P3HT) and 6,6-phenyl C61 butyric acid methylester (PCBM) based inverted PSCs with ZnO electron transporting layer have been developed by using layered magnetron sputtered ZnO and/or ionic liquid functionalized carbon nanopartilces (ILCNs) modification. The power conversion efficiencies (PCEs) of PSCs with ZnO layer sputtered with Ar and Ar/O(2) gas are 2.2% and 2.8%, respectively. PSCs modified with ILCNs or layered sputtered ZnO can respectively reach 3.4% and 3.1%, and further up to 3.8% using layered sputtered ZnO and ILCNs integrated modification. PSCs using modified ZnO layer show the vanishment of negative capacitive behavior, lowering reverse dark current and better diode characteristics. The results indicated that using layered sputtered ZnO or ILCNs, or both integrated modification can efficiently inhibit the defects of ZnO interface and improve contact quality ZnO/P3HT?PCBM interface. However, this integrated modification method is a more efficient strategy to enhance ZnO layer electron transporting and extraction capabilities, and further improve PCEs of PSCs.

AB - Aim: The aim of the study was to assess the effectiveness of the inclusion in the scheme remaxol treatment of metabolic syndrome in patients with nonalcoholic steatohepatitis and diabetes mellitus 2 type. Materials and methods: Data of 76 patients with metabolic syndrome in a non-alcoholic steatohepatitis and type 2 diabetes were analyzed. Patients were randomized by gender and age, and are divided into 2 groups according to the scheme of therapy: patients in group I (major - 38) conducted a basic therapy in combination with remaxol: intravenous infusion of 400 ml of 1 times a day for 10 days, group II patients (comparison - 38) combined basic therapy with intravenous ademetionine: 400 mg, in a solution diluted NaCL 0,9% 400 ml 1 time per day for 10 days. In addition to standard clinical and laboratory tests were studied biochemical parameters of liver activity, lipid and carbohydrate metabolism in the dynamics: before therapy and after its completion. Results: It was found that the inclusion in the scheme of drugs from the group of succinates (remaxol) reduces the severity of metabolic syndrome by reducing the manifestations of cholestasis and cytolysis, and improving lipid and glucose metabolism. As a result, significantly reduced the severity of the main clinical syndromes: asthenovegetative 46% and dyspeptic syndromes - 46% and 15%, respectively.

AB - Issue: Small-business owners have seen significant gains in health care coverage for themselves and their employees thanks to the Affordable Care Act. Though efforts to repeal the law failed in 2017, the current administration continues to take steps that undermine the law's progress. In recent months, new rules have been announced that allow more groups to establish association health plans and extend the length of short-term health insurance plans. These changes are likely to impact the stability of the marketplaces and coverage rates for the small business community. Goal: Examine the Affordable Care Act's impact on small businesses, solo entrepreneurs, and small-business employees. Methods: Analysis of ACA small-business enrollment data from established sources, including federal agencies and nonpartisan health care research foundations, supplemented by analysis of U.S. Census data. Findings and Conclusions: Because of the creation of the individual marketplaces and the expansion of Medicaid, more entrepreneurs and small-business employees have health coverage than before the ACA was implemented. Indeed, the uninsured rate for small-business employees fell by almost 10 percentage points post-ACA. The ACA also has helped stabilize health costs for many small businesses that provide coverage, with the rate of small business premium increases falling by half following implementation of the law.

AB - We retrospectively reviewed the results of transscrotal orchidopexy in the surgical management of palpable testis. From January 2014 to June 2017, 130 male children with a total of 140 palpable undescended testes (UDT) underwent transscrotal orchidopexy. The charts were retrospectively reviewed for demographic data, preoperative position and mobility of the testis, patency of the peritoneal vaginal duct (PVD), and post-operative complications. The resting position of the testis and its traction towards the scrotum were assessed before surgery and under anaesthesia. The mean age of the patients was 4.6 years. The position of the testis assessed at surgery was in most cases at the external inguinal ring (62.8%), at the neck of the scrotum (15.7%), in the inguinal canal (12.8%), or in an ectopic position (8,5%). A PVD was found in 66 testes (47.1%). Two surgical cases required an inguinal incision. In each patient, the postoperative course was unremarkable. The testicle at 1-year follow-up was in a scrotal position in 134 cases, but 6 patients required a second surgical intervention for re-ascent of the testis. No testicular atrophy or inguinal hernias were observed. Transscrotal orchidopexy is a simple and effective procedure for the treatment of palpable UDT. The incidence of complications is low and manageable, with rapid postoperative recovery and early resumption of normal activities.

PMID- 30280884 TI - Biological Activation of Bioinert Medical High-Performance Oxide Ceramics by Hydrolytically Stable Immobilization of c(RGDyK) and BMP-2. AB - High-performance oxide ceramics (HPOC), such as alumina, zirconia, and dispersion ceramics thereof are successfully used as articulating components in joint arthroplasty. HPOC exhibit excellent wear resistance, high strength, and cytocompatible behavior; however, they lack sufficient tissue bonding capability. Thus, they are primarily deployed as low-wear-bearing articulating components in arthroplasty without direct tissue contact, although proper cellular stimulation would hold significant advantages. Here, we describe a surface modification approach for HPOC, enabling hydrolytically stable interfacial binding of c(RGDyK) peptides and BMP-2 proteins to significantly improve the adhesion and osteogenic differentiation of human mesenchymal stem cells (hMSCs) without altering the mechanical properties of the underlying ceramic substrates. Analyses of cellular attachment of murine fibroblasts (L929), human alveolar basal epithelial cells (A549), hMSCs on c(RGDyK), and osteogenic differentiation of hMSCs on BMP-2 coated interfaces demonstrate significant improvements of cell adhesion and an enhanced osteogenic differentiation potential in vitro. The presented approach provides a strategy for the development of a novel class of bioactive HPOC with osseointegration potential that could lead to novel therapeutic solutions for biomedical applications. Furthermore, the developed surface modification is designed in a way to be readily translated to other medically employed bioinert materials in the future. PMID- 30280885 TI - High Throughput, Direct Determination of 226Ra in Water and Digested Geological Samples. AB - A method was developed for direct measurements of 226Ra in water samples with triple quadrupole inductively coupled plasma mass spectrometry (ICP-QQQ). The limit of detection was 0.42 pg L-1 226Ra (15 mBq L-1, 0.42 pCi L-1), which is compliant with the specifications for methods used for routine analysis of drinking water quality according to European and U.S. regulations. The use of N2O as reaction gas ensured that no separation before analysis was necessary. Water samples with high total dissolved solids (conductivity >100 mS cm-1) were also successfully analyzed after a simple dilution, yet the associated detection limit was higher (17 pg L-1, 0.61 Bq L-1, 16 pCi L-1). 226Ra content in soil and rock samples was determined with the same method after acid (HNO3 + H3PO4) digestion and dilution, resulting in a limit of detection of 0.75 ng kg-1 (27 Bq kg-1, 0.74 nCi L-1). Analysis of water samples was achieved within 2 min on a running instrument, while the preparation and analysis of 15 geological samples can be completed in 3 h. The key advantages of this direct analysis method are short preparation time, low labor intensity, low sample input (2 mL for water samples, 0.2 g for geological material), high sample throughput (2 min sample to sample, >150 samples measured in 8 h), and use of standard ICP-QQQ hardware. Overall, the proposed method offers a new opportunity for measuring a large number of samples with minimal effort and, in turn, for improving emergency preparedness, environmental monitoring, and data collection for environmental modeling.

PMID- 30280886 TI - Quantifying Surface Temperature of Thermoplasmonic Nanostructures. AB - Precise measurement of the temperature right at the surface of thermoplasmonic nanostructures is a grand challenge but extremely important for the photochemical reaction and photothermal therapy. We present here a method capable of measuring the surface temperature of plasmonic nanostructures with surface-enhanced Raman spectroscopy, which is not achievable by existing methods. We observe a sensitive shift of stretching vibration of a phenyl isocyanide molecule with temperature (0.232 cm-1/ degrees C) as a result of the temperature-dependent molecular orientation change. We develop this phenomenon into a method capable of measuring the surface temperature of Au nanoparticles (NPs) during plasmonic excitation, which is validated by monitoring the laser-induced desorption process of the adsorbed CO on Au NP surface. We further extend the method into a more demanding single living cell thermometry that requires a high spatial resolution, which allows us to successfully monitor the extracellular temperature distribution of a single living cell experiencing cold resistance and the intracellular temperature change during the calcium ion transport process. PMID- 30280888 TI - Structural Characterization of Acidic Compounds in Pyrolysis Liquids Using Collision-Induced Dissociation and Fourier Transform Ion Cyclotron Resonance Mass Spectrometry. AB - In this study, a novel approach to characterize and identify acidic oil compounds utilizing the fragmentational behavior of their corresponding precursor ions is presented. Precursor ions of seven analyzed pyrolysis oils that were generated from pyrolysis educts of different origins and degrees of coalification were produced by electrospray ionization in the negative ion mode (ESI(-)). Following a fragmentation of all ions in the ion cloud by collision-induced dissociation (CID), the precursor and product ions were subsequently detected by ultrahigh resolving Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). The ESI(-)-CID data sets were evaluated by applying either a targeted classification or untargeted clustering approach. In the case of the targeted classification, 10% of the ionized precursor ions of the analyzed pyrolysis liquid samples could be classified into one of 11 compound classes utilizing theoretical fragmentation pathways of these classes. In contrast, theoretical fragmentation pathways were not necessary for the untargeted clustering approach, making it the more transmittable method. Results from both approaches were verified by analyzing standard compounds of known structure. The analysis and data evaluation methods presented in this work can be used to characterize complex organic mixtures, such as pyrolysis oils, and their compounds in-depth on a structural level. PMID- 30280889 TI - Reduction and Increase in Thermal Conductivity of Si Irradiated with Ga+ via Focused Ion Beam. AB - Focused ion beam (FIB) technology has become a valuable tool for the microelectronics industry and for the fabrication and preparation of samples at the micro/nanoscale. Its effects on the thermal transport properties of Si, however, are not well understood nor do experimental data exist. This paper presents a carefully designed set of experiments for the determination of the thermal conductivity of Si samples irradiated by Ga+ FIB. Generally, the thermal conductivity decreases with increasing ion dose. For doses of >1016 (Ga+/cm2), a reversal of the trend was observed due to recrystallization of Si. This report provides insight on the thermal transport considerations relevant to engineering of Si nanostructures and interfaces fabricated or prepared by FIB. PMID- 30280890 TI - Posttranslational Chemical Mutagenesis: To Reveal the Role of Noncatalytic Cysteine Residues in Pathogenic Bacterial Phosphatases. AB - The field of chemical site-selective modification of proteins has progressed extensively in recent decades to enable protein functionalization for imaging, drug delivery, and functional studies. In this Perspective, we provide detailed insight into an alternative use of site-selective protein chemistry to probe the role(s) of unpaired Cys residues in the structure and function of disease relevant proteins. Phosphatases are important players in the successful infection of pathogenic bacteria, which represent a significant health burden, particularly in multi-drug-resistant strains. Therefore, a strategy for readily probing the key amino acid role(s) in structure and function may facilitate the targeting and inhibition of these virulence factors. With a dehydroalanine-based posttranslational chemical mutagenesis approach, it is possible to reveal hitherto unknown function(s) of noncatalytic Cys residues and confirm their role and interplay in pathogenic bacterial phosphatases. By selectively modifying reactive sulfhydryl side chains in different protein local environments, this posttranslational site-selective chemical mutagenesis approach reveals structural information about binding pockets and regulatory roles of the modified residues, which can be further validated by conventional site-directed mutagenesis. Ultimately, these new binding pockets can serve as templates for enhanced structure-based drug design platforms and aid the development of potent and specific inhibitors. PMID- 30280891 TI - Resonant Transport in Single Diketopyrrolopyrrole Junctions. AB - We study the single-molecule transport properties of small bandgap diketopyrrolopyrrole oligomers (DPP n, n = 1-4) with lengths varying from 1 to 5 nm. At a low bias voltage, the conductance decays exponentially as a function of length indicative of nonresonant transport. However, at a high bias voltage, we observe a remarkably high conductance close to 10-2 G0 with currents reaching over 0.1 MUA across all four oligomers. These unique transport properties, together with density functional theory-based transport calculations, suggest a mechanism of resonant transport across the highly delocalized DPP backbones in the high bias regime. This study thus demonstrates the unique properties of diketopyrrolopyrrole derivatives in achieving highly efficient long-range charge transport in single-molecule devices. PMID- 30280892 TI - Metal-Doping of La5.4MoO11.1 Proton Conductors: Impact on the Structure and Electrical Properties. AB - La5.4MoO11.1 proton conductors with different metal doping (Ca2+, Sr2+, Ba2+, Ti4+, Zr4+, and Nb5+) have been prepared and structurally and electrically characterized. Different polymorphs are stabilized depending on the doping and cooling rate used during the synthesis process. The most interesting results are obtained for Nb-doping, La5.4Mo1- xNb xO11.1- x/2, where single compounds are obtained in the compositional range 0 <= x <= 0.2. These materials are fully characterized by structural techniques such as X-ray and neutron powder diffraction and transmission electron microscopy, which independently confirm the changes of polymorphism. Scanning electron microscopy and impedance spectroscopy measurements in dry/wet gases (N2, O2, and 5% H2-Ar) showed an enhancement of the sinterability and electrical properties of the materials after Nb-doping. Conductivity measurements under very reducing conditions revealed that these materials are mixed ionic-electronic conductors, making them potential candidates for hydrogen separation membranes. PMID- 30280893 TI - Ultrasensitive Characterization of Charge Heterogeneity of Therapeutic Monoclonal Antibodies Using Strong Cation Exchange Chromatography Coupled to Native Mass Spectrometry. AB - In therapeutic monoclonal antibody (mAb) development, charge heterogeneity of a mAb molecule is often associated with critical quality attributes and is therefore monitored throughout development and during QC release to ensure product and process consistency. Elucidating the cause of each charge variant species is an involved process that often requires offline fractionation by ion exchange chromatography (IEX) followed by mass spectrometry (MS) analysis, largely due to the incompatibility of conventional IEX buffers for direct MS detection. In this study, we have developed a method that combines a generic strong cation exchange (SCX) chromatography step with ultrasensitive online native MS analysis (SCX-MS) optimized for mAb separation and detection. As demonstrated by analyzing mAb molecules with a wide range of pI (isoelectric point) values, the developed method can consistently achieve both high-resolution IEX separation and ultrasensitive MS detection of low-abundance charge variant species. Using this method, we analyzed the charge heterogeneity of NISTmAb reference material 8671 (NISTmAb) at both whole antibody and subdomain levels. In particular, due to the high sensitivity, a nonconsensus Fab glycosylation site, present at a very low level (<0.1%), was directly detected in the NISTmAb sample without any enrichment. The structure and location of this Fab glycosylation was further characterized by peptide mapping analysis. Despite the extensive characterization of NISTmAb material in previous studies, this is the first time that this Fab-glycosylated variant has been identified in the NISTmAb, demonstrating the value of this new method in achieving a more comprehensive characterization of charge heterogeneity for therapeutic mAbs. PMID- 30280895 TI - Integrated and Quantitative Proteomic Approach for Charting Temporal and Endogenous Protein Complexes. AB - Proteins often assemble into multiprotein complexes for carrying out their biological functions. Affinity purification combined with mass spectrometry (AP MS) is a method of choice for unbiasedly charting protein complexes. Typically, genetically tagged bait protein and associated proteins are immunoprecipitated from cell lysate and subjected to in-gel or on-bead digestion for MS analysis. However, the sample preparation procedures are often time-consuming and skipping reduction and alkylation steps results in incomplete digestion. Here, by seamlessly combining AP with the simple and integrated spintip-based proteomics technology (SISPROT), we developed an integrated AP-MS workflow for simultaneously processing more than 10 AP samples from cells cultured in six-well plates in 2 h. Moreover, we developed a quantitation-based data analysis workflow for differentiating potential interacting proteins from nonspecific interferences. The AP-SISPROT ensures high digestion efficiency especially for large transmembrane proteins such as EGFR and high quantification precision for profiling temporal interaction network of key EGFR signaling protein GRB2 across four time points of EGF treatment. More importantly, the integration feature allows minimum sample lose and helps the development of an ideal AP-MS workflow for studying endogenous protein complexes by the CRISPR Cas9 technology for the first time. By generating endogenously expressed bait protein fused with affinity tag, protein complexes associated with endogenous Integrin-linked kinase (ILK) was identified with much higher selectivity as compared with overexpressed and tagged ILK. The AP-SISPROT technology and its combination with CRISPR Cas9 technology should be generally applicable for studying protein complexes in a more efficient and physiologically relevant manner. PMID- 30280896 TI - Influences of Light Intensity and beta-Carotene on Polycyclic Aromatic Hydrocarbons and Aldehydes in Vegetable Oil: A Case Study Using Palm Oil. AB - This study investigated the effects of three light intensities on four types of palm oils during consecutive storage for 12 months at 4 degrees C. The concentrations of 4-hydroxy-2- trans-hexenal (4-HHE), 4-hydroxy-2- trans-nonenal (4-HNE), polycyclic aromatic hydrocarbon (PAH)4, and PAH8 in the oils significantly increased with the increasing light intensity after storage. The red palm oil had the lowest rate of increase of 4-HNE, while 5 degrees palm oil had the highest rate of increase of the PAH, OPAH, 4-HNE, and peroxide values during storage. For the same type of oil, OPAHs increased significantly under a light intensity of 6000 lx (lx) after storage. The increasing concentrations of 9FO, ATQ, and BaPO in the oils stored at 6000 lx showed a positive relation to their corresponding parent PAHs, indicating that PAH oxidation occurred at 6000 lx. The results suggest that light intensity and beta-carotene may control PAHs, OPAHs, and 4-hydroxy-trans- alkenals for vegetable oil storage, transportation, and retail. PMID- 30280894 TI - Reversible and Site-Dependent Proton-Transfer in Zeolites Uncovered at the Single Molecule Level. AB - Zeolite activity and selectivity is often determined by the underlying proton and hydrogen-transfer reaction pathways. For the first time, we use single-molecule fluorescence microscopy to directly follow the real-time behavior of individual styrene-derived carbocationic species formed within zeolite ZSM-5. We find that intermittent fluorescence and remarkable photostability of carbocationic intermediates strongly depend on the local chemical environment imposed by zeolite framework and guest solvent molecules. The carbocationic stability can be additionally altered by changing para-substituent on the styrene moiety, as suggested by DFT calculations. Thermodynamically unstable carbocations are more likely to switch between fluorescent (carbocationic) and dark (neutral) states. However, the rate constants of this reversible change can significantly differ among individual carbocations, depending on their exact location in the zeolite framework. The lifetimes of fluorescent states and reversibility of the process can be additionally altered by changing the interaction between dimeric carbocations and solvated Bronsted acid sites in the MFI framework. Advanced multidimensional magic angle spinning solid-state NMR spectroscopy has been employed for the accurate structural elucidation of the reaction products during the zeolite-catalyzed dimerization of styrene in order to corroborate the single molecule fluorescence microscopy data. This complementary approach of single molecule fluorescence microscopy, NMR, and DFT collectively indicates that the relative stability of the carbocationic and the neutral states largely depends on the substituent and the local position of the Bronsted acid site within the zeolite framework. As a consequence, new insights into the host-guest chemistry between the zeolite and aromatics, in terms of their surface mobility and reactivity, have been obtained. PMID- 30280897 TI - Identification of beta-Sitosterol as in Vitro Anti-Inflammatory Constituent in Moringa oleifera. AB - beta-Sitosterol is a well known phytosterol in plants, but owing to its poor solubility in typical media, determining its cellular mechanisms has been proven to be difficult. In this study, we investigated the anti-inflammatory activity of beta-sitosterol (BSS) isolated from Moringa oleifera in two cell lines. Over a dose range of 7.5 to 30 MUM, BSS dispersed well in the medium as nanoparticles with diameters of 50 +/- 5 nm and suppressed the secretion of inflammatory factors from keratinocytes and macrophages induced by PGN, TNF-alpha, or LPS, such as TNF-alpha, IL-1beta, IL-6, IL-8, and ROS, separately. In addition, BSS significantly reduced the expression of NLRP3, a key component of NLRP3 inflammasomes, and inhibited the activation of caspase-1. There was partial inhibition of NF-kappaB in macrophages. This is the first study to report an increase in the solubility of nearly water-insoluble phytosterols via the formation of nanoparticles and to delineate the formulation's capacity to inhibit the signal transduction pathways of inflammation in macrophages. PMID- 30280898 TI - Photocatalytic Activation of Less Reactive Bonds and Their Functionalization via Hydrogen-Evolution Cross-Couplings. AB - Cross-coupling reactions have been established as potential tools for manufacture of complex molecular frameworks of diversified interests by connecting two simple molecules through the formation of a carbon-carbon (C-C) or a carbon-heteroatom (C-X) bond. Conventional cross-couplings are transition metal-catalyzed reactions between electrophiles and nucleophiles. Generally, the electrophilic partner is an aryl or alkenyl halide, the nucleophile is an organometallic reagent, and both are obtained from prefunctionalization of their corresponding hydrocarbons. During the past decade, transition metal-catalyzed dehydrogenative cross couplings between two carbon-hydrogen (C-H) bonds and between one C-H bond and one heteroatom-hydrogen (X-H) bond, which build a C-C and a C-X linkage respectively, have emerged as an attractive strategy in synthetic chemistry. Such straightforward couplings allow use of less functionalized reagents, thus reducing the number of steps to the target molecule and minimizing waste production. However, such reactions involve the use of stoichiometric amounts of sacrificial oxidants such as peroxides, high-valent metals, and iodine(III) oxidants. This leads to low atom economy and possible generation of toxic wastes. Recently, visible light photocatalytic dehydrogenative cross-coupling reactions have received much attention due to their potential in utilizing sunlight as a source of energy making the process appealing. In this approach, metal complexes, organic dyes, or semiconductor quantum dots that absorb visible light are employed as photocatalysts. Upon irradiation, photocatalyst initiates single electron transfer with substrate(s) to generate a radical cation or radical anion of the substrate, which undergoes the desired reaction of interest. In this case, molecular oxygen is utilized as the oxidant with the formation of hydrogen peroxide as the only byproduct. These aspects make the process much greener than the corresponding transition metal-catalyzed dehydrogenative cross-coupling reactions. Research efforts from our group have led to the development of an environmentally benign strategy to construct a C-C bond from two different C-H bonds and to construct a C-X bond from one C-H bond and one X-H bond by visible light photocatalysis. Our approach, photocatalytic hydrogen-evolution cross coupling reactions, combines a photocatalyst with a proton reduction cocatalyst to create a dual catalyst system. The former catalyst uses light energy as the driving force for the cross-coupling, while the latter catalyst may capture electrons from the substrates or reaction intermediates to reduce the protons eliminated from the reactive scaffolds (C-H/C-H or C-H/X-H bonds) into molecular hydrogen (H2). Thus, without use of any sacrificial oxidant and under mild conditions, our dual catalyst system affords cross-coupling products with excellent yields with generation of an equimolar amount of H2 as the sole byproduct. The photocatalytic hydrogen-evolution cross-coupling is highly step and atom economical and particularly useful for reactions that involve species sensitive to oxidative conditions. This Account highlights the findings from our laboratories on photocatalytic hydrogen-evolution cross-coupling reactions featuring activation and functionalization of C(sp3)-H bonds adjacent to amino groups and to oxygen atoms in ethers, aromatic C(sp2)-H bonds, and several types of X-H bonds. We expect that this strategy for combining photocatalytic activation of C-H and X-H bonds with proton reduction holds significant potential for development of atom economical and environmentally benign transformations.

AB - We report the use of air-stable Cu(I)-NHC complex 4a as a catalyst for the efficient microwave-assisted synthesis of peptidotriazoles on solid phase. Compared with the usual conditions (CuI or CuSO4/NaAsc), catalyst 4a allowed the preparation of a series of peptidomimetic compounds containing a 1,2,3-triazole ring in their backbone without the oxidation of common side-chains.

PMID- 30280900 TI - Delivery of Doxorubicin Using Double-Layered Core-Shell Nanocarrier Based on Magnetic Fe3O4 Core and Salep Shells. AB - Herein, we developed a magnetic drug delivery system based on magnetic Fe3O4 nanoparticles with double shells of modified salep polysaccharide for the delivery of doxorubicin (Dox). The drug-loaded nanocarrier was synthesized in an easy way, and large amounts of drug molecules were loaded into the nanocarrier. The drug-loaded nanocarrier showed excellent pH responsibility in vitro, and large amounts of Dox were released at lower pH (60% release), whereas the nanocarrier was stable at neutral pH. The hemolysis assay results showed that the nanocarrier has negligible hemolytic effects on human red blood cells and showed good biocompatibility. Moreover, the result of coagulation assays showed that the nanocarrier was not active in any coagulation pathways. Cytotoxicity assays of nanocarrier and drug-loaded nanocarrier toward HeLa cells demonstrated that the nanocarrier has negligible toxicity, whereas the drug-loaded nanocarrier kills more than 90% of cells during 48 h. The flow cytometry analysis also showed that the uptake of drug-loaded nanocarrier into the cancerous cells is time-dependent and higher concentrations of drug internalized into the cells at longer incubation time. On the basis of the results, we suggest that the present nanocarrier can be applicable for in vivo drug delivery as an easy-made and cheap nanocarrier.

PMID- 30280902 TI - Diffusiophoresis of a Charged Porous Particle in a Charged Cavity. AB - The quasi-steady diffusiophoresis of a charged porous sphere situated at the center of a charged spherical cavity filled with a liquid solution of a symmetric electrolyte is analyzed. The porous particle can represent a solvent-permeable and ion-penetrable polyelectrolyte molecule or floc of nanoparticles in which fixed charges and frictional segments are uniformly distributed, whereas the spherical cavity can denote a charged pore involved in microfluidic or drug delivery systems. The linearized electrokinetic differential equations governing the ionic concentration, electric potential, and fluid velocity distributions in the system are solved by using a perturbation method with the fixed charge density of the particle and the zeta-potential of the cavity wall as the small perturbation parameters. An expression for the diffusiophoretic (electrophoretic and chemiphoretic) mobility of the confined particle with arbitrary values of a/ b, kappa a, and lambda a is obtained in closed form, where a and b are the radii of the particle and cavity, respectively; kappa and lambda are the reciprocals of the Debye screening length and the length characterizing the extent of flow penetration into the porous particle, respectively. The presence of the charged cavity wall significantly affects the diffusiophoretic motion of the particle in typical cases. The diffusio-osmotic (electro-osmotic and chemiosmotic) flow occurring at the cavity wall can substantially alter the particle velocity and even reverse the direction of diffusiophoresis. In general, the particle velocity decreases with an increase in a/ b, increases with an increase in kappa a, and decreases with an increase in lambda a, but exceptions exist.

PMID- 30280904 TI - Trichophycins B-F, Chlorovinylidene-Containing Polyketides Isolated from a Cyanobacterial Bloom. AB - NMR-guided isolation (based on 1D 1H and 13C NMR resonances consistent with a chlorovinylidene moiety) resulted in the characterization of five new highly functionalized polyketides, trichophycins B-F (1-5), and one nonchlorinated metabolite tricholactone (6) from a collection of Trichodesmium bloom material from the Gulf of Mexico. The planar structures of 1-6 were determined using 1D and 2D NMR spectroscopy, mass spectrometry, and complementary spectroscopic procedures. Absolute configuration analysis of 1 and 2 were carried out by 1H NMR analysis of diastereomeric Mosher esters in addition to ECD spectroscopy, J-based configuration analysis, and DFT calculations. The absolute configurations of 3-6 were proposed on the basis of comparative analysis of 13C NMR chemical shifts, relative configurations, and optical rotation values to compounds 1 and 2. Compounds 1-5 represent new additions to the trichophycin family and are hallmarked by a chlorovinylidene moiety. These new trichophycins and tricholactone (1-6) feature intriguing variations with respect to putative biosynthetic starting units, halogenation, and terminations, and trichophycin E (4) features a rare alkynyl bromide functionality. The phenyl-containing trichophycins showed low cytotoxicity to neuro-2A cells, while the alkyne containing trichophycins showed no toxicity. PMID- 30280905 TI - Alterations in serum zinc and polyunsaturated fatty acid concentrations in treatment naive HIV-diagnosed alcohol dependent subjects with liver injury. AB - Heavy alcohol drinking causes alterations in the metabolism of fatty acids and zinc that participate in inflammation and liver injury. Human Immunodeficiency Virus (HIV) infection has been reported to cause dysregulated polyunsaturated fatty acid (PUFAs) and zinc metabolism. In this pilot study, we examined the role of dysregulated PUFA metabolism and zinc deficiency in liver injury in the liver injury occurring in heavy drinkers with early stage HIV diagnosis. Fourteen heavy drinking alcohol dependent (AD) patients (seven with treatment naive HIV diagnosis [AD+HIV], and seven without HIV infection [AD]) participated in this study. Liver injury, serum zinc, PUFAs, viral load, CD4+ count, and drinking measures using Lifetime drinking history (LTDH), and Timeline Follow-back past 90 days (TLFB90) assessments were evaluated. Liver injury was also assessed in seven age- and sex-matched socially drinking HIV treatment-naive patients who served as disease controls. Liver enzymes were significantly elevated in both AD+HIV and AD patients, and AD+HIV patients had significantly higher ALT levels than did AD patients, even with lower drinking. Serum zinc was significantly lower in AD+HIV patients. Only AD+HIV patients showed a significant elevation in linoleic acid (LA) and alpha-linoleic acid (ALA) levels. Serum zinc and ALT; LA and ALT; and ALA and ALT were significantly associated only in AD+HIV patients. The association between LA and ALT showed a higher effect than did the ALA?and ALT association in the AD+HIV patients. Interestingly, AD+HIV subjects (who drank less) nevertheless showed more liver injury compared to AD patients, who reported heavier drinking. HIV viral load by itself did not show any correlation with liver injury. We speculate that the the underlying proinflammatory response resulting from zinc deficiency and an elevation in serum LA likely contributed to liver injury in AD+HIV patients, even with a comparatively lower degree of heavy drinking.

AB - We examined associations of 25-hydroxy vitamin D (25-OHD), tenofovir disoproxil fumarate (TDF), and bone toxicity. We studied TDF/emtricitabine (FTC) HIV pre exposure prophylaxis (PrEP) in young men who have sex with men (YMSM). Bone toxicity was predefined using bone mineral density/content change from baseline to week 48. Baseline serum 25-OHD was dichotomized as <20 ng/mL (insufficient/deficient) versus >=20 (sufficient), and week 48 dried blood spot tenofovir diphosphate (TFV-DP) as >700 fmol/punch (protective against HIV acquisition) versus <=700. Associations were examined by univariate and multivariable logistic regression, reporting crude and adjusted odds ratios (ORs), with 95% confidence intervals (CIs). Of 101 enrolled, 69 had complete bone assessments and 25-OHD; of these, 59 had week 48 TFV-DP data. Median (Q1-Q3) age was 20 (18-21) years; 54% were black/African American. In univariate analysis, participants with baseline 25-OHD <20 ng/mL (OR = 5.4; 95% CI = 1.9-16.5) and blacks (OR = 4.9; 95% CI = 1.7-15.2) had greater odds of bone toxicity than those with 25-OHD >=20 or other races. TFV-DP was not associated with bone toxicity (OR = 1.6; 95% CI = 0.5-5.5). In multivariable analysis, compared with those with 25 OHD >=20 and TFV-DP <=700, those with 25-OHD >=20 and TFV-DP >700 (OR = 11.5; 95% CI = 1.4-169.6), 25-OHD <20 and TFV-DP <=700 (OR = 19.4; 95% CI = 3.0-228.7), and 25-OHD <20 and TFV-DP >700 (OR = 32.3; 95% CI = 3.3-653.6) had greater odds of bone toxicity after adjusting for race. In multivariable models, 25-OHD insufficiency, protective TFV-DP concentrations, and black race were significantly associated with bone toxicity after 48 weeks of TDF/FTC PrEP in YMSM. Clinical Trials Registration: NCT01769469. PMID- 30280907 TI - Demonstrating efficacy and effectiveness in clinical studies with recurrent event as primary end point: a chronic obstructive pulmonary disease example. AB - Pivotal clinical trials of persistent disorders such as chronic obstructive pulmonary disease and severe asthma often utilize recurrent event (e.g., exacerbations) as primary study end point. Such infrequent and correlated end points usually have skewed distributions, which can result in clinical efficacy criterion being met even while clinical effectiveness may be poor. Patients, prescribers and, increasingly, payers want evidence of both a medicine's clinical efficacy and its effectiveness. This duality in evidentiary requirements is causing a shift from the traditional one-size-fits-all blockbuster drug development paradigm to newer patient-centric models. Using a simulated study, we illustrate how clinical studies using enrichment designs can collect and present such patient-centric evidence that will simultaneously demonstrate clinical efficacy and effectiveness, while increasing probability of trial success and overall efficiency. PMID- 30280908 TI - Percutaneous Nephrolithotomy with Different Temperature Irrigation and Effects on Surgical Complications and Anesthesiology Applications. AB - OBJECTIVE: Percutaneous nephrolithotomy (PCNL) is a widely accepted and frequently performed operation for large kidney stones. However, there is not much information about the effects of irrigation fluid temperature as well as many other factors that affect success and complications during the operation. In this study, we aimed to investigate the surgical and anesthesiological effects of irrigation fluid used in body temperature and room temperature during and after PCNL. MATERIAL AND METHODS: A total of 108 PCNL patients were performed between June 2016 and April 2018. The half of these patients (54) were performed with body temperature (37 degrees C) irrigation fluid, hence known as body temperature group (BTG), and the other half with room temperature (22 degrees C) irrigation fluid, called as room temperature group (RTG). For the study, we recorded the body temperature of the patients during and after the operation, the amount of irrigation fluid used, the size and location of the kidney stones, the duration of the operation, postoperative shivering time during the patient's wake-up period, pre- and postoperative hemoglobin value, additional blood requirements, postoperative analgesic requirements, and postoperative urinary tract infections. RESULTS: The age of patients, gender distribution, height, weight, body mass index, stone size, and postoperative analgesic requirement showed no significant differences in two groups. The postoperative body heat was significantly higher in the BTG than the RTG. The duration of waking was significantly higher in the RTG than the BTG. The amount of hemorrhage was significantly less in the patients who were irrigated in the RTG. CONCLUSION: The temperature of the irrigation fluid can affect many parameters in the PCNL. We recommend using irrigation in room temperature especially with patients having bleeding risks and irrigation fluid in body temperature especially with patients having anesthetic risks for easier waking process. PMID- 30280909 TI - Prospective Associations between Weekend Catch-Up Sleep, Physical Activity, and Childhood Obesity. AB - BACKGROUND: Catch-up sleep and low physical activity on weekends have been commonly documented. Preliminary evidence on Chinese children, however, has shown a variety of weekly physical activity patterns. This study examined the prospective associations between weekend catch-up patterns of sleep and physical activity and obesity over a 2-year period in Chinese children. METHODS: Prospective data from 599 children in the Understand Children's Activity and Nutrition (UCAN) cohort study were analyzed. Weekly patterns of obesogenic behaviors (physical activity and sleep duration) were assessed annually over a 2 year period. Moderate-to-vigorous physical activity (MVPA) and sedentary time were determined by ActiGraph accelerometry. Data on sleep durations and sociodemographic factors were obtained from parental-reported questionnaires. Weekend catch-up sleep and MVPA patterns were calculated and examined in relation to childhood obesity after controlling for sociodemographic variables and sedentary time. RESULTS: Every additional hour of average weekly sleep duration was associated with a 16% decrease in the odds of obesity (OR: 0.841, 95%CI: 0.709 - 0.999). After adjustment of average sleep duration, weekend sleep catch up categories showed no association with obesity risk. Over a 2-year period, half of the children demonstrated weekend catch-up MVPA. Weekend catch-up MVPA for less than 20 minutes (OR: 0.473, 95%CI: 0.258 - 0.867) or more than 20 minutes (OR: 0.505, 95%CI: 0.257 - 0.993) were both related to lower risk of obesity. CONCLUSIONS: Weekend catch-up sleep did not ameliorate the risk of childhood obesity, whereas weekend catch-up MVPA did reduce that risk. More research is needed to explore the factors contributing to these obesogenic behavior patterns. PMID- 30280910 TI - What gives them the right? Legal privilege and waivers of consent for research. AB - Waivers of informed consent for research participation are permitted in the United States under the Common Rule, the Health Insurance Portability and Accountability Act regulations, and the US Food and Drug Administration's Exception from Informed Consent rule for emergency research. We assess the novel question regarding what legal right researchers have to carry out research procedures on or about another person, be it experimental medical intervention, psychological or social manipulation, or invasion of privacy, without the permission of their subjects. Our analysis frames waivers of consent as a species of presumed consent, and we address the underlying empirical question of whether it is reasonable to believe that subjects from whom no consent is sought would in fact agree, if asked. A scoping review of what is known about participation and refusal rates in United States-based research suggests that a large minority, on average, do not agree to take part in research. Refusal rates vary widely. This suggests that, while researchers may assert the social utility of their studies are high enough to justify waivers, there is reason to suspect that many who would be enrolled under a waiver of consent would not want to be enrolled. We conclude that waivers should be rare and that institutional review boards and researchers must explicitly address study acceptability in the community at large and the target population of their proposed research. PMID- 30280911 TI - ENDOSCOPIC INTRAVESICAL FIBRIN GLUE APPLICATION IN THE TREATMENT OF REFRACTORY HEMORRHAGIC RADIATION CYSTITIS: A SINGLE COHORT PILOT STUDY. AB - Objective To evaluate the clinical value of endoscopic fibrin glue (FG) application therapy in treating hemorrhagic radiation cystitis (HRC). Patients and Methods This is a single cohort, prospective pilot study. We collected data from patients with HRC who were treated at our urology unit during the period May 2014 to December 2016. Patients with grade >=2 HRC for whom conventional therapy and trans-urethral endoscopic electrocoagulation had failed were treated with endoscopic intravesical FG. The mean follow-up was 26.2 +/- 9.78 months. Our analysis included data on patient demographics, pelvic malignancies, radiotherapy regimens, total dose of radiation received, time of onset and severity of hematuria, and previous intravesical management. Following the FG intervention, patients' clinical status was defined as either: (1) clinical response, absence of dysuria, urgency, and frequency; discontinuation of analgesic medication; and Foley catheter removal, but with ongoing hematuria grade <2; (2) complete response, clinical response and no further hematuria; or (3) no response, no clinical response and sustained hematuria. Results A total of 20 patients (12 women and 8 men, with a mean age of 69 +/- 7.5 years) were treated with 12 mL of FG intravesically, using endoscopic application. Of the 20 patients, 16 (80%) had a complete response and 4 (20%) had a clinical response. In the case of four patients (20%), treatment was carried out twice. Mean hospital stay was 6 +/- 2.5 days. The intervention showed good tolerability in all patients. No major adverse events were reported. Bladder spasms were the only minor adverse events reported in 6 patients (30%). Conclusion Application of FG is an effective, practical, affordable and repeatable procedure for the treatment of grade >=2 HRC. PMID- 30280912 TI - Food Service Workers: Reliable Assessors of Food Intake in Hospitalized Patients. AB - Early detection of malnutrition in hospitalized patients is of paramount importance. As poor food intake is a marker of malnutrition risk, a simple and accurate method to monitor intake is valuable. This quality assurance project aimed to determine if food service workers (FSW) were able to provide accurate estimates of patient intakes through visually assessing meal trays at an acute care hospital. FSW conducted visual estimates of patient trays after meals using the meal plate pictorial rating scale adapted from the My Meal Intake Tool and translated their estimates into one of 5 consumption levels (0%, 25%, 50%, 75%, or 100%). A total of 401 patient meal estimates were validated using the food weighing method. Spearman's correlations between percent calories consumed (determined by weight) and estimates by FSW were 0.624 (n = 137, P < 0.001), 0.771 (n = 134, P < 0.001), and 0.829 (n = 130, P < 0.001), for breakfast, lunch, and supper, respectively. Paired Wilcoxon tests and the Kruskal-Wallis H test showed that accuracy varied for breakfast, lunch, and supper. The overall sensitivity and specificity of FSW for detecting patient intake <=50% was 81% and 88%, respectively. These findings identify that FSW can accurately estimate patient intake, contributing an important marker for the detection of malnutrition. PMID- 30280913 TI - Determining Student Food Insecurity at Memorial University of Newfoundland. AB - PURPOSE: Our study compared the prevalence of food insecurity among 3 student groups attending Memorial University of Newfoundland (MUN): International (INT), Canadian out-of-province (OOP), and Newfoundland and Labrador (NL). Factors associated with food insecurity were also investigated. METHODS: Data were collected via an online survey distributed to an estimated 10 400 returning MUN students registered at a campus in St. John's, NL. Respondents were recruited through e-mails, posters, and social media. Ten questions from the Canadian Household Food Security Survey Module adult scale were asked to assess food security. Logistic regression was used to compare rates of food insecurity between the three population subgroups. RESULTS: Of the 971 eligible student respondents, 39.9% were food insecure (moderate or severe). After controlling for program type, parental status, living arrangement, and primary income source, OOP and INT students were 1.63 (95% CI = 1.11-2.40) and 3.04 (95% CI = 1.89-4.88) times more likely, respectively, to be food insecure than NL students. CONCLUSIONS: Approximately 40% of participating MUN students experienced food insecurity, a higher proportion than reported for the overall provincial population. Groups at high risk of food insecurity include INT students, students with children, and those relying on government funding as their primary income. PMID- 30280914 TI - Parental views of antenatal testing and termination following a diagnosis of cleft lip. AB - Fetal anomaly screening at 18-21 weeks now routinely includes cleft lip. If detected, the manner in which the diagnosis is communicated can considerably influence prospective parents' decision-making in regard to further testing and termination of pregnancy (TOP). Given the known psychological impact of an antenatal diagnosis of cleft lip on prospective parents, this study aimed to explore the decision-making process from the parents' perspective, in order to evaluate how well current practice is meeting guidelines. Data from 217 parents of children born with cleft lip (with or without cleft palate) were collected using a mixed-methods online survey. Respondents reported feeling upset, offended and/or anxious following the diagnosis, due to unsatisfactory information and a perceived lack of empathy from health professionals. Some respondents had felt under pressure to make a decision quickly, with a minority having regretted undergoing amniocentesis, and/or experiencing significant distress at having come close to TOP unnecessarily. A number of suggestions are made as to how the discussion between parents and health professionals could be improved, to ensure that the information and support needs of families affected by cleft lip are fully addressed. PMID- 30280915 TI - Three Distraction Methods for Pain Reduction During Cystoscopy: A Randomized Controlled Trial Evaluating the Effects on Pain, Anxiety, and Satisfaction. AB - BACKGROUND: Cystoscopy is a safe diagnostic procedure commonly used to evaluate lower urinary tract symptoms. This can cause pain, anxiety, and dissatisfaction in patients undergoing cystoscopy. OBJECTIVES: The aim of this study was to compare the effects on pain, anxiety, and satisfaction of distraction methods used during cystoscopy. DESIGN: Single-center, open-label, randomized, parallel group trial. SETTING: Cystoscopy unit of a training and research hospital in Turkey. PARTICIPANTS: Male patients >=18 years of age who underwent rigid cystoscopy for the first time. METHODS: A total of 120 male patients were recruited and randomized into four groups as music, stress ball, video, and control group. Data were collected using visual analog scale for pain and satisfaction, State-Trait Anxiety Inventory for anxiety, and hemodynamic parameters. The primary outcome was the difference with respect to pain scores among intervention groups. Other outcome measures were anxiety and satisfaction scores. RESULTS: Pain severity during cystoscopy was found to be significantly lower in the intervention groups than the control group. In the video group, the severity of pain during cystoscopy was also found to be significantly lower than music and stress ball groups (p = 0.006, p < 0.001). After cystoscopy, anxiety levels were significantly lower and satisfaction levels were significantly higher in the intervention groups than in the control group. Anxiety levels were significantly lower in the video group than music and stress ball groups (p < 0.001, p < 0.001). Satisfaction levels were also significantly higher after cystoscopy in the video group than in the music and stress ball groups (p = 0.018, p = 0.018). CONCLUSIONS: According to this study, distraction methods used during rigid cystoscopy were found to have a reducing effect on pain, anxiety, and dissatisfaction. As the results of the study are evaluated, video should be recommended to be the first preferred distraction method during rigid cystoscopy.

PMID- 30280917 TI - Exploring Social Justice Advocacy in Dietetic Education: A Content Analysis. AB - PURPOSE: To explore the extent to which knowledge- and skill-based learning regarding social justice and/or social justice advocacy is included in the course descriptions of required courses of accredited, English-speaking dietitian training programs in Canada. METHODS: This study is a mixed-methods content analysis of required course descriptions sampled from university academic calendars for accredited, English-speaking dietitian training programs across Canada. RESULTS: Quantitative analysis showed that required course descriptions (n = 403) included few instances of social justice-related terminology (n = 63). Two themes emerged from the qualitative analysis: competing conceptualizations of social issues and dietitians' roles; prioritization of science-based knowledge and ways of knowing. CONCLUSIONS: Accredited, English-speaking dietitian training programs in Canada appear to include little knowledge- or skill-based learning regarding social justice issues and advocacy. Supporting future dietitians to pursue leadership roles in redressing social injustices and socially just dietetic practice may require more explicit education and training about social justice issues and advocacy skills. PMID- 30280918 TI - Grocery Shopping, Dinner Preparation, and Dietary Habits among Adolescents and Young Adults in Canada. AB - PURPOSE: The current study aimed to characterize grocery shopping and dinner preparation behaviours among young people in Canada and to examine associations with eating habits. METHODS: A cross-sectional online survey was conducted with 2008 participants aged 16-24 from across Canada. The survey measured self reported grocery shopping and dinner preparation behaviours, frequency of eating breakfast and eating meals prepared away from home, frequency of vegetable and fruit intake, and socio-demographic characteristics. Chi-square tests examined differences in proportions; logistic and linear regressions examined dietary habits, including covariates for grocery shopping and dinner preparation and socio-demographics. RESULTS: Overall, 37.3% had helped with grocery shopping in the past week, and 84.3% had participated in dinner preparation at least 1 day in the past week. Engaging in shopping at least once weekly was associated with increased vegetable and fruit consumption only, whereas more frequent engagement in dinner preparation was associated with increased vegetable and fruit consumption, more frequent breakfast consumption, and fewer meals consumed that were prepared away from home (P < 0.001 for all). CONCLUSIONS: Increased participation in grocery shopping and dinner preparation were associated with healthier dietary habits. Interventions that increase these behaviours may contribute to improving dietary behaviours among adolescents and young adults.

PMID- 30280920 TI - Describing Food Availability in Schools Using Different Healthy Eating Guidelines: Moving Forward with Simpler Nutrition Recommendations. AB - PURPOSE: Internationally, there is debate on whether a nutrient or a food-based approach to policy is more effective. This study describes the food/beverage availability in schools in Nova Scotia through a comparison of a traditional nutrient classification ("Maximum/Moderate/Minimum"), currently used in the provincial school policy and a simplified food-based system ("Core/Extra"). METHODS: School food environment audits were conducted in schools (n = 25) to record the food and beverages available. Registered dietitians categorized information using both the nutrient-based and simplified food-based classification systems. Number and percent in each category were described for items. RESULTS: Food and beverage items consisted of breakfast, lunch, snacks, beverages, and vending of which 81% were permissible by the policy, whereas only 54% were categorized as Core. Many snacks and vending items classified as Extra fell within either Moderate (45% and 35%, respectively) or Minimum (29% and 33%, respectively) categories. CONCLUSIONS: Dietitians have a role to support interpretation of classification systems for school nutrition policies. The nutrient-based classification used in the policy permitted some items not essential to a healthy diet as defined by the Extra food-based classification. However, the food-based Core/Extra categorization had less detail to classify nutrients. PMID- 30280921 TI - Effect of Testosterone Use on Bone Mineral Density in HIV-Infected Men. AB - HIV-infected men have increased rates of osteoporosis and fracture compared to HIV-uninfected men. Testosterone use among HIV-infected men is common. In HIV uninfected men, testosterone increases bone mineral density (BMD), but its effects have not been evaluated in HIV-infected men. In a substudy of Multicenter AIDS Cohort Study (MACS), the Bone Strength Substudy (BOSS) enrolled 202 HIV infected and 201 HIV-uninfected men aged between 50 and 69 years. Study participants underwent dual-energy X-ray absorptiometry (DXA) at the lumbar spine (LS), total hip (TH), and femoral neck (FN) and detailed assessment of osteoporosis risk factors. We used multivariable linear regression to determine associations and 95% confidence intervals (CIs) between self-reported testosterone use and T-scores at the LS, TH, and FN after adjustment for demographics, behavioral covariates, comorbidities, and other traditional osteoporosis risk factors. HIV-infected men reported more frequent testosterone use (22% vs. 4%; p < .001) and had lower median BMD T-score at TH than HIV uninfected men (0.0 vs. 0.3; p = .045) but similar T-scores at LS and FN. In the overall study population, testosterone use was associated with significantly greater BMD T-score at LS (0.68; 95% CI: 0.22-1.13). In HIV-infected men with virologic suppression, testosterone was significantly associated with higher BMD T-score at LS (0.95; 95% CI: 0.36-1.54) and TH (0.45; 95% CI: 0.04-0.86). Current testosterone use is common in HIV-infected men and was associated with higher BMD, compared to those not taking testosterone. Testosterone's role in reducing fracture risk in HIV-infected men should be investigated. PMID- 30280922 TI - Survey of Nutrition Practice in Patients with Severe Sepsis among Canadian Registered Dietitians. AB - PURPOSE: The purpose of this study was to determine the opinions and reported nutrition practices of Canadian Registered Dietitians (RDs) with regard to feeding patients with severe sepsis. METHODS: In 2017, surveys were sent to 112 eligible Canadian RDs in 10 provinces who were practicing in an intensive care environment. The survey included embedded branching logic questions developed to address major facets of sepsis, critical illness, and nutrition. The survey instrument assimilated all data in an anonymous manner, so respondents could not be linked to their answers. RESULTS: Of the 64 RDs who responded (57% response rate), the majority practiced in adult intensive care (81%), within an academic center (59%), and in a mixed unit (73%). A wide variability of Canadian RDs' opinions and practice was reported in determining energy requirements, enteral nutrition (EN) practice, EN with vasoactive agents, parenteral nutrition (PN), and supplemental micronutrients. CONCLUSIONS: Practice variability of Canadian RDs likely reflects gaps in both evidence and guidelines for severe sepsis. Further research efforts are needed to customize nutritional requirements in the patient with evolving sepsis, EN with patients at high risk for gastrointestinal dysfunction, optimizing PN, and the role of micronutrients. PMID- 30280923 TI - 'It's different for girls': Gender differences in the friendships and conflict of autistic and neurotypical adolescents. AB - This mixed-methods study examined gender differences in the friendships and conflict experiences of autistic girls and boys relative to their neurotypical peers. In total, 102 adolescents (27 autistic girls, 26 autistic boys, 26 neurotypical girls, and 23 neurotypical boys), aged between 11 and 18 years completed the Friendship Qualities Scale, the Revised Peer Experiences Questionnaire and were interviewed about their friendships. Results demonstrated that in many ways, the friendships and social experiences of autistic girls are similar to those of neurotypical girls. Autistic girls, however, have significantly more social challenges than their neurotypical peers, experiencing more conflict and finding that conflict harder to manage successfully. Autistic boys showed quantitatively different friendship patterns to all other groups. There were consistent gender differences in the type of conflict which boys and girls experienced, regardless of diagnostic status. These findings suggest that gender, rather than diagnosis per se, plays a critical role in the way that autistic adolescents perceive and experience their social relationships. PMID- 30280924 TI - The rationale for combination therapy in patients with aggressive B-cell non Hodgkin lymphoma: ten questions. AB - Rituximab plus cyclophosphamide, doxorubicin, vincristine, prednisone immunochemotherapy remains standard of care for first-line treatment of diffuse large B-cell lymphoma (DLBCL). High-dose chemotherapy and stem cell transplantation is offered to most relapsing/refractory patients who respond to salvage therapy. This Q&A review evaluates recommended management strategies for second and subsequent lines of therapy in patients with DLBCL, outlining the relative efficacies of currently available options including novel agents such as ibrutinib and CAR-T cells. The combination of pixantrone and rituximab is currently under investigation as a second-line treatment for patients ineligible for stem cell transplantation, while pixantrone monotherapy is the only therapeutic option approved for multiply relapsed and refractory DLBCL beyond the second line at this time. PMID- 30280925 TI - Dietary Changes Albertan Women Make During Pregnancy: Thematic Analysis of Self reported Changes and Reasons. AB - PURPOSE: To explore dietary changes Albertan women make during pregnancy, reasons they make changes, and alignment with prenatal nutrition recommendations. METHODS: Women up to 6 months postpartum were recruited in public health centres and Primary Care Networks. Qualitative data were collected through a self administered survey including 2 open-ended questions that asked about changes made to food/beverage intake during pregnancy and why these changes were made. RESULTS: A majority (n = 577) of the 737 women completing the survey described changes they made to their food/beverage intake during pregnancy and 193 respondents provided reasons for these changes. Increased intake of fruits/vegetables, meat, milk, and their alternatives (n = 600); limiting or avoidance of foods/beverages known to be harmful during pregnancy (n = 445); and increased food/fluid intake or meal/snack frequency (n = 405) were commonly reported dietary changes. Motivations relating to health and to control physiological changes/manage health conditions were the most frequent reasons provided. CONCLUSIONS: Women make diverse dietary changes and have various motivations for food choices during pregnancy. A majority make dietary changes to support a healthy pregnancy. However, the motivation to control discomforts and respond to hunger and thirst sensations reflect a stronger influencer on women's choices than is currently addressed in prenatal nutrition messages. PMID- 30280926 TI - Dynamics of testosterone levels in patients with newly detected glucose abnormalities and acute myocardial infarction. AB - OBJECTIVE:: Low testosterone has been associated with increased cardiovascular risk and glucose abnormalities. This study explored the prevalence of low testosterone, dynamics over time and prognostic implications in acute myocardial infarction patients with or without glucose abnormalities. METHODS:: Male acute myocardial infarction patients (n = 123) and healthy controls (n = 124) were categorised as having normal or abnormal glucose tolerance (impaired glucose tolerance or diabetes) by oral glucose tolerance testing. Testosterone was measured at hospital admission, discharge, 3 and 12 months thereafter in patients. Patients and controls were followed for 11 years for major cardiovascular events (cardiovascular death/acute myocardial infarction/stroke/severe heart failure). RESULTS:: At hospital admission, more patients had low testosterone (?300 ng/dl) and lower median levels than controls (64 vs 28%; p < 0.001 and 243 vs 380 ng/dl; p < 0.01). At the subsequent time points, testosterone had increased to 311, 345 and 357 ng/dl. Patients with abnormal glucose tolerance had the highest prevalence (75%) of low levels. In adjusted Cox regression models, neither total nor free testosterone predicted major cardiovascular events. CONCLUSION:: Low testosterone levels were common in male acute myocardial infarction patients in the acute phase, especially in the presence of abnormal glucose tolerance, but increased over time indicating that testosterone measured in close proximity to acute myocardial infarction should be interpreted with caution. PMID- 30280927 TI - Maternal Prepregnancy Overweight and Obesity Are Associated with Reduced Physical Fitness But Do Not Affect Physical Activity in Childhood: The Amsterdam Born Children and Their Development Study. AB - BACKGROUND: Maternal overweight/obesity during pregnancy increases offspring's risks of obesity and cardiovascular disease (CVD). A possible pathway is by reduced physical fitness and physical activity (PA) levels in children of overweight/obese mother. We assessed whether maternal prepregnancy overweight/obesity independently determines cardiorespiratory fitness (CRF), muscular strength, moderate-to-vigorous physical activity (MVPA), and sedentary behavior (SB) in 8- to 9-year-old children. We also assessed whether child's fat mass (FM) mediates these associations. METHODS: One hundred ninety-four children of Dutch ethnicity aged 8.6 (+/- 0.4) years were randomly selected from a prospective birth cohort, the Amsterdam Born Children and their Development (ABCD) study. CRF was assessed by the 20-m multistage shuttle run test (20-m MSRT), muscular strength by hand dynamometry, and MVPA and SB by accelerometry. The association of prepregnancy body mass index (BMI) >= 25 kg/m2 with these outcome measures was assessed by multivariable linear regressions. RESULTS: Mean (+/- standard deviation) attained 20-m MSRT stage was 5.3 (+/- 1.7). Compared with children from normal weight women, children of women with prepregnancy overweight/obesity attained a 0.80 (95% confidence interval: 0.15-1.50) lower stage, adjusted for child's sex and MVPA. This association was not mediated by birthweight or child's FM at age 5 years. Maternal prepregnancy overweight/obesity was not associated with child's muscular strength, MVPA, or SB. CONCLUSIONS: Maternal prepregnancy overweight/obesity was associated with reduced childhood CRF, but not with muscular strength, PA, or SB. Birthweight and FM at age 5 years did not mediate this association. Reduced CRF may partly explain the increased CVD risk in children of overweight/obese women. PMID- 30280928 TI - Cephalometric comparison of adult anterior open bite treatment using clear aligners and fixed appliances. AB - OBJECTIVES:: To compare fixed appliances and clear aligner therapy in correcting anterior open bite and in controlling the vertical dimension in adult patients with hyperdivergent skeletal patterns. MATERIALS AND METHODS:: In this retrospective study, two treatment groups of adult (>=18 years old) hyperdivergent patients (mandibular plane angles of >=38 degrees ) with anterior open bites were included: 17 fixed appliance patients and 36 clear aligner patients. Thirteen cephalometric measurements representing the vertical dimension were reported for each group. A two-sample t-test was used to assess differences in changes in mandibular plane angle and overbite between the two treatment groups. RESULTS:: There were no statistical differences found in the magnitude of overbite correction and the changes in any of the cephalometric measurements for vertical control. The clear aligner group showed a slightly greater amount of lower incisor extrusion ( P = .009). The main mechanism of open bite correction was similar between the two treatment groups and was accomplished through retroclination of the upper and lower incisors while maintaining the vertical position of the upper and lower molars. CONCLUSIONS:: Cephalometric comparison of anterior open bite correction and changes in the mandibular plane angle associated with use of clear aligners and fixed appliances did not demonstrate statistically significant differences in adult hyperdivergent patients.

PMID- 30280929 TI - Topology of the Structural Social Brain Network in Typical Adults. AB - Although a large body of research has identified discrete neuroanatomical regions involved in social cognition and behavior (the "social brain"), the existing findings are based largely on studies of specific brain structures defined within the context of particular tasks or for specific types of social behavior. The objective of the current work was to view these regions as nodes of a larger collective network and to quantitatively characterize both the topology of that network and the relative criticality of its many nodes. Large-scale data mining was performed to generate seed regions of the social brain. High-quality diffusion MRI data of typical adults were used to map anatomical networks of the social brain. Network topology and nodal centrality were analyzed using graph theory. The structural social brain network demonstrates a high degree of global functional integration with strong local segregation. Bilateral dorsomedial prefrontal cortices and amygdala play the most central roles in the network. Strong probabilistic evidence supports modular divisions of the social brain into subnetworks bearing good resemblance to functionally classified clusters. The present network-driven approach quantifies the structural topology of the social brain as a whole. This work can serve as a critical benchmark against which to compare (1) developmental change in social brain topology over time (from infancy through adolescence and beyond) and (2) atypical network topologies that may be a sign or symptom of disorder (as in conditions such as autism, Williams syndrome, schizophrenia, and others).

AB - Staphylococcus aureus is an important pathogen implicated in various diseases, including staphylococcal food poisoning. Bacteriocins are considered safe and effective antimicrobial substances for the prevention of the growth of pathogenic bacteria. In this article, we describe the purification and characterization of pasteuricin, a novel bacteriocin produced by Staphylococcus pasteuri RSP-1. A cell-free supernatant of S. pasteuri RSP-1 exerted strong antimicrobial activity against staphylococci, including methicillin-resistant S. aureus (MRSA), and gram positive bacteria. The loss of antimicrobial activity upon treatment with proteolytic enzymes confirmed the proteinaceous nature of pasteuricin. A rapid and pronounced bactericidal effect of pasteuricin was confirmed by a live-dead bacterial viability assay. To our knowledge, pasteuricin is the first reported S. pasteuri bacteriocin that inhibits S. aureus. Because pasteuricin is characterized by strong antimicrobial activity and high stability, it has potential as an alternative antimicrobial agent to antibiotics. PMID- 30280937 TI - Cryopreservation of Human Adipose-Derived Stem Cells for Use in ex vivo Regional Gene Therapy for Bone Repair. AB - The development of an ex vivo regional gene therapy clinical pathway using adipose-derived stem cells (ASCs) may require cryopreservation for cell culture, storage, and transport prior to clinical use. ASCs isolated from five donors were transduced with a lentiviral vector containing BMP-2. Three groups were assessed: transduction without cell freezing (group 1), freezing of cells for 3 weeks followed by transduction (group 2), and cell transduction prior to freezing (group 3). Nontransduced cells were used as a control. The cluster of differentiation (CD) marker profiles, cell number, BMP-2 production, and osteogenic potential were measured. The CD marker profile (CD44, CD73, CD90, and CD105) was unchanged after cryopreservation. Cell number was equivalent among cryopreservation protocols in transduced and nontransduced cells. There was a trend toward decreased BMP-2 production in group 3 compared to groups 1 and 2. Osteogenic potential based on Alizarin red concentration was higher in group 2 compared to group 3, with no difference compared to group 1. Freezing ASCs prior to transduction with a lentiviral vector containing BMP-2 has no detrimental effect on cell number, BMP-2 production, osteogenic potential, or immunophenotype. Transduction prior to freezing, however, may limit the BMP-2 production and potential osteogenic differentiation of the ASCs. PMID- 30280938 TI - Hair follicle miRNAs: a novel biomarker for primary blast Induced-Mild traumatic brain injury. AB - CONTEXT: Due to the wide use of improvised explosive devices during modern warfare, primary blast-derived mild traumatic brain injury (mTBI) has become a major medical condition in the military. With minimal visually identifiable symptoms, an effective molecular biomarker system is desirable. OBJECTIVE: We assessed the potential of mammalian hair follicle miRNAs as an mTBI biomarker. MATERIALS AND METHODS: Due to their well-established roles in mTBI molecular pathology, the expression level of miR-183, miR-26a, miR-181c, miR-29a, miR-34a and miR-27b was determined using qRT-PCR in whisker hair follicles from rats subject to head-only exposure to a single-pulse shock wave. Based on established transcriptomics profiles, sub-network enrichment analysis (SNEA) was also conducted. RESULTS: The results revealed that molecular networks involving miR 183, miR-26a and miR-181c were enriched in multiple treatments, whereas sub networks of miR-29a, miR-34a and miR-27b were unique to individual exposure groups. DISCUSSION: Our study showed that all six miRNAs were reflective of the mTBI signature involved in cellular responses. Noteworthy was that the decrease in the transcript levels of miR-181c was correlated with shockwave exposure severity. CONCLUSION: This study demonstrates for the first time that mammalian hair follicles are capable of housing miRNA biomarkers for TBI. PMID- 30280939 TI - Synthetic Toll-like receptor agonists for the development of powerful malaria vaccines: a patent review. AB - INTRODUCTION: Currently, there is no efficient vaccine available against clinical malaria. However, continuous efforts have been committed to develop powerful antimalarial vaccine by discovery of novel antigens with in-depth understanding of its nature, immunogenicity, and presentation (delivery adjuvants). Moreover, another important part of vaccine development includes discovery of better immunostimulatory formulation components (immunostimulants). A protective vaccine against malaria requires antigen-specific B and T helper cell responses as well as cytotoxic T lymphocyte (CTL) responses. A long-lasting B and T memory cell production is also required for effective malaria vaccine. Since activation of Toll-like receptors (TLRs) promotes both innate inflammatory responses as well as the induction of adaptive immunity, several initiatives have been mounted during the last few years for the use of TLR agonists as malaria vaccine adjuvants. Areas covered: The review summarizes reports related to the use and development of TLR agonists as malaria vaccine adjuvants and describes various strategies involved for the selection of specific antigens and TLR agonists. Expert opinion: TLR agonists are promising adjuvants for the development of effective malaria vaccine, allowing for both innate inflammatory responses as well as the induction of adaptive immunity. PMID- 30280940 TI - Pembrolizumab for the treatment of gastric cancer. AB - INTRODUCTION: Gastric cancer is one of a few gastrointestinal malignancies in which immunotherapy has shown meaningful activity. Pembrolizumab is the first and only immune checkpoint inhibitor to be FDA-approved in gastric cancer. Areas Covered: This review summarizes the current and emerging clinical evidence for immune checkpoint inhibitors in advanced and metastatic gastric cancer, with a focus on pembrolizumab. Expert Commentary: Pembrolizumab has shown impressive activity in the third-line treatment of locally advanced and metastatic gastric cancer. It is currently being studied as upfront therapy in combination with chemotherapy. The emerging understanding of the molecular alterations and tumor immune microenvironment as predictors of immunotherapy response in gastric cancer are discussed. The impact of gastric mucosal dysbiosis on gastric carcinogenesis and the modulation of immunotherapy response by the gut microbiome are also reviewed. PMID- 30280941 TI - The effect of polymer molecular weight and cell seeding density on viability of cells entrapped within PEGDA hydrogel microspheres. AB - Cell microencapsulation can be used in tissue engineering as a scaffold or physical barrier that provides immunoisolation for donor cells. When used as a barrier, microencapsulation shields donor cells from the host immune system when implanted for cell therapies. Maximizing therapeutic product delivery per volume of microencapsulated cells necessitates first optimising the viability of entrapped cells. Although cell microencapsulation within alginate is well described, best practices for cell microencapsulation within polyethylene glycol is still being elucidated. In this study we microencapsulate mouse preosteoblast cells within polyethylene glycol diacrylate (PEGDA) hydrogel microspheres of varying molecular weight or seeding densities to assess cell viability in relation to cell density and polymer molecular weight. Diffusion studies revealed molecule size permissible by each molecular weight PEGDA towards correlating viability with polymer mesh size. Results demonstrated higher cell viability in higher molecular weight PEGDA microspheres and when cells were seeded at higher cell densities.

AB - BACKGROUND: Adults with intellectual and developmental disabilities (I/DD) experience barriers to community participation, yet their insider experiences of environmental barriers and supports to participation are largely absent from the literature. AIM/OBJECTIVE: The aims of this research were to evaluate Photovoice as a participatory research method, examine environmental barriers and supports to community participation, and develop strategies to support self-determination and community participation for and with people with I/DD. MATERIAL AND METHOD: This study utilized a participatory action research (PAR) approach in which participants used Photovoice during interviews and audits of participation environments to identify high interest participation activities and document supports and barriers in these environments. Data analysis utilized an iterative, participatory approach in which researchers and participants teamed up to select, contextualize, and codify the data. Thematic analyses involved both inductive and realist approaches. RESULTS/FINDINGS: Participants included 146 community dwelling adults with I/DD from three U.S. urban sites. We present a conceptual model of nine themes at microsystem, mesosystem, exosystem, macrosystem, and chronosystem environmental levels. CONCLUSIONS: Using Photovoice as a participatory method to strategize community participation can help ground systems change efforts in the voices of people with I/DD. SIGNIFICANCE: By including people with I/DD in conversations that concern them, researchers and practitioners can support this population in ways that they find meaningful. PMID- 30280943 TI - PEG-PCL modification and intestinal sustained-release of solid lipid nanoparticles for improving oral bioavailability of 2-methoxyestradiol. AB - The primary purpose of the present study was to design and optimize a solid lipid nanoparticle (SLN) formulation of the poorly water-soluble drug 2 methoxyestradiol (2-ME) to improve its oral bioavailability and prolong the duration of therapeutic drug level. SLN was modified by amphipathic PEG-PCL (PLN) and then encapsulated in pH-sensitive microparticles (MP) by spray drying technology. Several properties of 2-ME PLN-MP were characterized including particle size, drug loading and drug or PLN release. After oral administration of 2-ME PLN-MP, retention time in mice were evaluated by in vivo imaging technology and the pharmacokinetic parameters in rats were determined by HPLC. The results demonstrated that PEG-PCL modification of 2-ME SLN significantly decreased particle size and delayed drug release without influencing IC50 in 4T1 cells. 2 ME PLN in the microparticles showed significant pH-sensitive release in the simulated gastrointestinal fluid and controlled release in the intestine. The PLN (labeled with IR-780 iodide) prolonged significantly fluorescence duration time compared to the SLN and the prolongation was further enhanced by the PLN-MP formulation. Furthermore, as compared to the suspension, the PLN-MP formulation showed a 56.66-fold delay in Tmax, a 10.36-fold extension in MRT and a 140.86 fold increase in the relative bioavailability in rat. The research work in the paper suggests that the PLN-MP could serve as a practical oral preparation for 2 ME in future cancer therapy. PMID- 30280944 TI - A structural perspective on the PP-loop ATP pyrophosphatase family. AB - Derived from an ancient ATP-hydrolyzing Rossmann-like fold protein, members of the PP-loop ATP pyrophosphatase family feature an absolutely conserved P-loop like "SxGxDS/T" motif used for binding and presenting ATP for substrate adenylylation (AMPylation). Since the first family member was reported more than 20 years ago, numerous representatives catalyzing very diverse reactions have been characterized both functionally and structurally. The availability of more than 100 high quality structures in the protein data bank provides an excellent opportunity to gain structural insights into the generally conserved catalytic mechanism and the uniqueness of the reactions catalyzed by family members. In this work, we conducted a thorough database search for the PP-loop ATP pyrophosphatase family members, resulting in the most comprehensive and up-to date collection that includes 18 enzyme families. Structure comparison of representative family members allowed us to identify common structure features in the core catalytic domain, as well as four highly variable regions that define the unique chemistry for each enzyme family. The newly identified enzymes, particularly those from pathogens, warrant further research to enlarge the scope of this ever-expanding and highly diverse enzyme superfamily for use in potential bioengineering and biomedical applications.

PMID- 30280946 TI - Vaginal bleeding/spotting with conjugated estrogens/bazedoxifene, conjugated estrogens/medroxyprogesterone acetate, and placebo. AB - OBJECTIVE: In the 1-year phase 3 Selective estrogens, Menopause, And Response to Therapy-5 trial, cumulative amenorrhea rates with conjugated estrogens/bazedoxifene (CE/BZA) were similar to placebo and higher than with conjugated estrogens/medroxyprogesterone acetate (CE/MPA). This post hoc analysis reports bleeding/spotting rates in 4-week intervals (cycles) and 3-month intervals (quarters) with these therapies and the percentage of cases attributable to spotting only. METHODS: Generally healthy postmenopausal women with menopausal symptoms recorded vaginal bleeding/spotting in daily diaries while receiving CE 0.45 mg/BZA 20 mg, CE 0.625 mg/BZA 20 mg, CE 0.45 mg/MPA 1.5 mg, or placebo. RESULTS: A total of 1596 women in the modified intent-to-treat population contributed data. Incidence of bleeding/spotting was significantly (p < 0.001) lower with CE 0.45 mg/BZA 20 mg (0.54-4.44%), CE 0.625 mg/BZA 20 mg (1.26-5.02%), and placebo (1.55-4.82%) compared with CE 0.45 mg/MPA 1.5 mg (8.81 25.63%) in all 4-week cycles. Each quarter, <10% of women taking CE/BZA doses or placebo had bleeding/spotting, significantly (p < 0.001) less than the 21-36% with CE 0.45 mg/MPA 1.5 mg. Odds ratio for bleeding/spotting with CE 0.45 mg/BZA 20 mg vs CE 0.45 mg/MPA 1.5 mg was 0.1 in each quarter (95% CI, Q1-Q3: 0.1-0.2; Q4: 0.1-0.3). Across all treatments, most (88-100%) bleeding/spotting cases were spotting only. Mean days of bleeding/spotting were <1 per quarter with CE/BZA doses and placebo, which was significantly (p < 0.01) less than the 3-5 days per quarter with CE/MPA. CONCLUSIONS: Bleeding/spotting with CE/BZA treatment was similar to placebo and significantly less frequent than with CE/MPA treatment. Most cases were spotting only across all treatments. PMID- 30280947 TI - Site specific hypermethylation of CpGs in Connexin genes 30, 26 and 43 in different grades of glioma and attenuated levels of their mRNAs. AB - AIM: Gliomas, the intracranial tumours are considered the deadliest malignancies. The gap junctional Connexins (Cxs) that maintain cellular homeostasis perform a unique function in glial tumour suppression. However, the differential methylation patterns of Cxs were not revealed in glioma so far. The current study attempts to categorise promoter methylation of Cx30 and Cx26 and intron methylation of Cx43 in different grades of human glioma. MATERIALS AND METHODS: About 85 glioma patients with pathologically confirmed grades and 15 control brain tissues were recruited in the study. Bisulphite-PCR-Single Stranded Conformation analysis(SSCA), Bisulphite sequencing and MeDIP-qPCR were carried out to assess methylation status and Cx mRNA levels were also analysed to evaluate the effect of methylation. RESULTS: We found that promoter CpG islands(CpGs) reside in Sp1 and Ap2 sites of Cx30 and 26 were hypermethylated in high grades (HG) of glioma rather than low grades. The input % of both was significantly increased (p < 0.03) in progressive grades. Interestingly, Cx43 could exhibit a significant increase (p < 0.05) in input % only in grade IV. While, Cx30 and 26 mRNAs were downregulated according to their methylation status in progressive fashion with grades, Cx43 was downregulated irrespective of intron methylation. CONCLUSION: Thus, we suggest that the sites and extent of methylation of Cxs (30 and 26 but not in 43) are found to be altered. In different grades of glioma can provide better appreciation of the grade of the patient and might help in strategies based on epigenetic approaches. PMID- 30280948 TI - Health Benefits In 2018: Modest Growth In Premiums, Higher Worker Contributions At Firms With More Low-Wage Workers. AB - The annual Henry J. Kaiser Family Foundation Employer Health Benefits Survey found that in 2018 the average annual premium for single coverage rose 3 percent to $6,896 and the average annual premium for family coverage rose 5 percent to $19,616. Covered workers contributed 18 percent of the cost for single coverage and 29 percent of the cost for family coverage, on average, with considerable variation across firms. Eighty-five percent of covered workers face a general annual deductible before they use most services, including the 29 percent of covered workers who are enrolled in a high-deductible health plan with a savings option. The share of firms covering services provided via telemedicine has increased steadily over the past several years. Nearly a quarter of large employers expect the elimination of the individual mandate to result in lower take-up in plan offerings.

PMID- 30280950 TI - Neonatal epidermolysis bullosa: Lessons to learn about genetic counselling. AB - Epidermolysis Bullosa (EB) is a heterogeneous group of congenital blistering diseases that usually presents in the neonatal period. EB is classified into three major categories, each with many subtypes based on the precise location at which separation or blistering occurs, namely epidermolysis bullosa simplex (EBS), junctional epidermolysis bullosa (JEB) and dystrophic epidermolysis bullosa (DEB). We describe genetics of neonatal EB in Hong Kong. Two neonates of consanguineous Pakistani parents had the EB-Pyloric Atresia (EB-PA) variant. One had a 4 kb homozygous deletion of exon 19-25 of the ITGB4 gene, and the other with only a histopathological diagnosis. Both died of sepsis in infancy. Aberrant COL7A1 mutations in the dominant and recessive EB were described. Genetic analysis, together with histopathological classification is important to aid prognosis and counselling. JEB and EB-PA are associated with consanguinity and mortality during infancy. Morbidity and prognosis of the autosomal dominant DEB is optimistic. The autosomal recessive DEB is more severe, with neonatal onset and recurrent blistering. It is also associated with chronicity and malignant changes when the child reaches adulthood. Exact genetic diagnosis aids in counselling of the family concerning the prognosis in the affected child and the risk of affected children in future pregnancies. PMID- 30280951 TI - Community-based participatory research to promote healthy lifestyles among Latino immigrant families with youth with disabilities. AB - BACKGROUND/AIMS: Community-based participatory research (CBPR) is an optimal approach that brings together community stakeholders, researchers and practitioners in an effort to understand and address social issues and health disparities experienced by vulnerable populations. Latino immigrant families in the United States with youth and young families with disabilities have experienced a number of barriers in gaining positive health outcomes. These families face challenges in maintaining a healthy lifestyle, placing them at high risk for obesity, diabetes, and other chronic health conditions. The purpose of this study was to develop a healthy lifestyles intervention in collaboration with Latino immigrant families with youth and young adults with disabilities using a CBPR approach, and to examine the impact of the intervention from participants' perspectives. METHODS: Grounded in the principles of CBPR, we developed a partnership with community stakeholders to create a healthy lifestyles intervention aimed at meeting the needs of Latino families in the United States. During and following implementation of the intervention, we conducted focus groups with 12 intervention participants to examine the impact of the intervention. RESULTS: Participants identified the intervention program as meeting a need in the community and reported specific positive aspects related to health behaviors, social learning, inclusion, community participation, and peer advocacy. DISCUSSION: CBPR healthy lifestyle interventions are relevant to the needs of Latino immigrant families with youth and young adults with disabilities. Health professionals should involve community residents in the design of healthy lifestyles programming to ensure strategies for change are relevant and relatable. PMID- 30280952 TI - Understanding health disparities for individuals with intellectual disability using photovoice. AB - BACKGROUND: Individuals with intellectual disability (ID) are at an increased risk for health disparities that serve as barriers to participation in daily occupations. Understanding the lived experience of individuals with ID can illuminate barriers and facilitators to these health-promoting occupations. Commonly used methods examining health for individuals with ID may not reveal important information about their daily participation potentially due to cognitive or communication limitations. Participatory action research including Photovoice is a viable alternative to meet their unique needs. OBJECTIVE: The purpose of this study was to describe the process of using a Photovoice method with individuals with ID and present results from two participants to understand their meaning of health. METHOD: An analysis of two participants is provided to illustrate the use of Photovoice. RESULTS: Three themes, Personal Identity of Health, Nutrition, and Meaningful Occupation were identified using photos, personal narratives, and focus group data. CONCLUSIONS: Participants had complex definitions of health that are better understood through the composite of narrative descriptions and visual data as compared to more commonly used research methods. The use of a Photovoice method allowed participants to communicate additional depth and complexity of their understanding of health that has not been previously captured. PMID- 30280953 TI - Major effects on blood-retina barrier passage by minor alterations in design of polybutylcyanoacrylate nanoparticles. AB - Because the blood-brain barrier (BBB) is an obstacle for drug-delivery, carrier systems such as polybutylcyanoacrylate (PBCA) nanoparticles (NPs) have been studied. Yet, little is known of how physiochemical features such as size, surfactants and surface charge influence BBB passage in vivo. We now used a rat model of in vivo imaging of the retina - which is brain tissue and can reflect the situation at the BBB - to study how size and surface charge determine NPs' ability to cross the blood-retina barrier (BRB). Interestingly, for poloxamer 188 modified, DEAE-dextran-stabilised, fluorescent PBCA NPs, decreasing the average zeta-size from 272 nm to 172 nm by centrifugation reduced the BRB passage of the NPs substantially. Varying the zeta potential within the narrow range of 0-15 mV by adding different amounts of stabiliser revealed that 0 mV and 15 mV were less desirable than 5 mV which facilitated the BRB passage. Moreover, whether the fluorescent marker was adsorbed or incorporated also influenced the transport into the retina tissue. Thus, minor changes in design of nano-carriers can alter physicochemical parameters such as size or zeta potential, thus substantially influencing NPs' biological distribution in vivo, possibly by interactions with blood constituents and peripheral organs. PMID- 30280954 TI - Toxicology and Pharmacology of an AAV Vector Expressing Codon-optimized RPGR in RPGR-deficient Rd9 Mice. AB - AGTC is developing a recombinant adeno-associated virus (rAAV) vector AGTC-501, also designated AAV2tYF-GRK1-RPGRco, to treat retinitis pigmentosa (RP) in patients with mutations in the retinitis pigmentosa GTPase regulator (RPGR) gene. The vector contains a codon-optimized human RPGR cDNA (RPGRco) driven by a photoreceptor-specific promoter (G protein-coupled receptor kinase 1, GRK1) and is packaged in an AAV2 capsid with three surface tyrosine residues changed to phenylalanine (AAV2tYF). We conducted a safety and potency study of this vector administered by subretinal injection in the naturally occurring RPGR-deficient Rd9 mouse model. Sixty Rd9 mice (20 per group) received subretinal injection in the right eye of vehicle (control) or AAV2tYF-GRK1-RPGRco at one of two dose levels (4 * 108 or 4 * 109 vg/eye) and were followed for 12 weeks after injection. Vector injections were well tolerated with no systemic toxicity. There was a trend towards reduced ERG b-wave amplitudes in the high vector dose group that was not statistically significant. There were no clinically important changes in hematology or clinical chemistry parameters and no vector-related ocular changes in-life or by histological examination. Dose-dependent immunolabeling of RPGR protein expression, mainly in the inner segment of photoreceptors and the adjacent connecting cilium region, was observed in all vector-treated eyes examined. Sequence integrity of the codon-optimized RPGR was confirmed by sequencing of PCR-amplified DNA, or cDNA reverse transcribed from total RNA, extracted from vector-treated retinal tissues, and by sequencing of RPGR protein obtained from transfected HEK 293 cells. These results support the use of rAAV2tYF-GRK1-RPGRco in clinical studies in patients with XLRP caused by RPGR mutations. PMID- 30280955 TI - Transcriptional quiescence in primordial germ cells. AB - In most animal species, newly formed primordial germ cells (PGCs) acquire the special characteristics that distinguish them from the surrounding somatic cells. Proper fate specification of the PGCs is coupled with transcriptional quiescence, whether they are segregated by determinative or inductive mechanisms. Inappropriate differentiation of PGCs into somatic cells is thought to be prevented due to repression of RNA polymerase (Pol) II-dependent transcription. In the case of a determinative mode of PGC formation (Drosophila, Caenorhabditis elegans, etc.), there is a broad downregulation of Pol II activity. By contrast, PGCs display only gene-specific repression in organisms that rely on inductive signaling-based mechanism (e.g., mice). In addition to the global block of Pol II activity in PGCs, gene expression can be suppressed in other ways, such as chromatin remodeling and Piwi-mediated RNAi. Here, we discuss the mechanisms responsible for the transcriptionally silent state of PGCs in common experimental animals, such as Drosophila, C. elegans, Danio rerio, Xenopus, and mouse. While a PGC-specific downregulation of transcription is a common feature among these organisms, the diverse nature of underlying mechanisms suggests that this functional trait likely evolved independently on several instances. We discuss the possible biological relevance of these silencing mechanisms vis-a-vis fate determination of PGCs. PMID- 30280956 TI - CIZ1-F, an alternatively spliced variant of the DNA replication protein CIZ1 with distinct expression and localisation, is overrepresented in early stage common solid tumours. AB - CIZ1 promotes cyclin-dependent DNA replication and resides in sub-nuclear foci that are part of the protein nuclear matrix (NM), and in RNA assemblies that are enriched at the inactive X chromosome (Xi) in female cells. It is subjected to alternative splicing, with specific variants implicated in adult and pediatric cancers. CIZ1-F is characterized by a frame shift that results from splicing exons 8-12 leading to inclusion of a short alternative reading frame (ARF), excluding the previously characterized C-terminal NM anchor domain. Here, we apply a set of novel variant-selective molecular tools targeted to the ARF to profile the expression of CIZ1-F at both transcript and protein levels, with focus on its relationship with the RNA-dependent and -independent fractions of the NM. Unlike full-length CIZ1, CIZ1-F does not accumulate at Xi, though like full-length CIZ1 it does resist extraction with DNase. Notably, CIZ1-F is sensitive to RNase identifying it as part of the RNA-fraction of the NM. In quiescent cells CIZ1-F transcript expression is suppressed and CIZ1-F protein is excluded from the nucleus, with re-expression not observed until the second cell cycle after exit from quiescence. Importantly, CIZ1-F is over-expressed in common solid tumors including colon and breast, pronounced in early stage but not highly proliferative late stage tumors. Moreover, expression was significantly higher in hormone receptor negative breast tumors than receptor positive tumors. Together these data show that CIZ1-F is expressed in proliferating cells in an unusual cell cycle-dependent manner, and suggest that it may have potential as a tumor biomarker. PMID- 30280957 TI - Evaluating cellular uptake of gold nanoparticles in HL-7702 and HepG2 cells for plasmonic photothermal therapy. AB - AIM: A novel methodology is provided to quantitatively measure the gold (Au) mass internalized in a cell for effective implementation of plasmonic photothermal therapy (PPTT). MATERIALS & METHODS: The cellular uptake of 4-mercaptobenzoic acid-labeled Au nanoparticles (NPs) is investigated via Raman mapping and inductively coupled plasma-mass spectrometry and the efficiency of in vitro PPTT is evaluated. RESULTS & CONCLUSION: The cellular uptake is strongly affected by the size of the Au NPs, concentration of the Au NPs, incubation time and cell type. By optimizing the experimental parameters, the results show that a significant damage is caused to the HepG2 cells and slight harm is caused to the HL-7702 cells during PPTT. This demonstrates a high potential for developing effective photothermal therapy for tumor tissues.

AB - Lesbian, gay, bisexual, transgender and other sexually and gender diverse persons negotiate for their identities, create communities and advocate for their rights throughout the world. However, there are limited data about the perceptions of social change among sexually and gender diverse persons in contexts where same sex sexual practices have been recently decriminalised, such as in 2010 in Lesotho. We conducted semi-structured in-depth interviews with sexually and gender diverse persons (n = 46) and six key informants. Findings were analysed using Social Worlds Theory. Participants discussed social constraints and marginalisation across structural (legal systems, employment, education), community (beliefs that sexual and gender diversity are incongruent with Basotho culture; stigma), and familial (tensions with religion and cultural gendered economic traditions) dimensions. The narratives also revealed perceived change across structural (changing norms in legal, employment and education spheres), community (larger community and LGBT community change), familial (negotiating acceptance), and internal (active resistance) domains. The findings reported here can inform multi-faceted programmes to challenge stigma, violence and gender inequity; build social capital; and address the health and human rights priorities of sexually and gender diverse persons in Lesotho. PMID- 30280959 TI - 'Age of despair', or 'when life starts': migrant and refugee women negotiate constructions of menopause. AB - There has been a call for research on migrant and refugee women's negotiation of diverse discourses and cultural constraints associated with sexual embodiment, including menopause, in order to facilitate sexual and reproductive health and understand gendered subjectivity. This study examined the construction and experience of menopause among migrant and refugee women who had settled in Australia or Canada in the last 10 years. Eighty-four individual interviews and 16 focus groups comprising 85 participants were conducted (total n = 169), with women aged 18 years and over from Afghanistan, India (Punjab), Iraq, Somalia, South Sudan, Sri-Lanka (Tamil), Sudan and various South American (Latina) backgrounds. Thematic decomposition identified three discursive themes: Menopause as the Age of Despair; a Discourse of Silence and Secrecy; and Menopause as a Life Stage - or when Life Starts. Negative constructions of menopause, associated with silence and secrecy, were evident across different cultural groups, with implications for women's positioning and experience of menopausal change and embodiment. However, resistance to negative discourse was also evident. This was primarily associated with having received menopause education and more open communication about menopausal change, suggesting that education and health information can facilitate affirming aspects of menopause. PMID- 30280960 TI - Primary Lymphedema of the Upper Extremities: Clinical and Lymphoscintigraphic Features in 23 Patients. AB - BACKGROUND: Primary idiopathic lymphedema is an uncommon condition that typically affects the lower extremities. Patients have a malformed lymphatic system that causes subcutaneous fluid and adipose deposition. Rarely, the disease also has been described in the upper extremities. The purpose of this study was to investigate a cohort of patients with primary arm lymphedema to better understand the disease. METHODS: Patients evaluated in our Lymphedema Program between 2008 and 2018 were reviewed for individuals with upper extremity primary lymphedema. Gender, age of onset, morbidity, associated features, and management were identified. Transit of radiolabeled tracer and dermal backflow on lymphoscintigraphy were recorded. RESULTS: Twenty-three patients of 234 individuals with primary lymphedema had upper extremity disease (9.8%). Eleven subjects were male. Age of onset was infancy (n = 15), adolescence (n = 5), or adulthood (n = 3). The disease affected the left arm (n = 11), right arm (n = 9), or both upper extremities (n = 3). Lymphoscintigraphy in 15 patients exhibited delayed transit of tracer and 2 illustrated dermal backflow. One-half of individuals also had primary lower extremity lymphedema (six unilateral and six bilateral). None of the patients in the cohort exhibited a family history of lymphedema. Two individuals had Turner syndrome. Morbidity included infection (n = 5), other lymphatic anomalies (n = 6), and lymphangiosarcoma (n = 1). CONCLUSIONS: The upper extremities are a rare location for primary lymphedema and patients often also have lymphedema of the legs. Compared with that of the lower extremities, primary disease of the arm is more likely to be associated with systemic lymphatic dysfunction and has a lower risk of familial transmission.

PMID- 30280962 TI - Biomechanical Effect Of Masticatory Forces In Tenting Screws Used For Vertical Ridge Augmentation : A 3D Finite Element Analysis. AB - The purpose of this study was to analyze stresses induced in tenting screws by occlusal forces in a vertically augmented ridge, using a three-dimensional finite element analysis (FEA).The study was performed by means of FEA with the use of tenting screws that stabilize non resorbable membrane in a vertically augmented ridge. A customized three-dimensional analysis was performed by computer simulation to determine the pattern of stress distribution in tenting screws and the surrounding bone when applying axial and off-axial forces. The magnitude of the stresses in the model were calculated during these simulations. Based on these findings, different stress patterns on tenting screws with axial and off axial forces did not cause mechanical instability. This study revealed that when applying vertical force, the maximum stress in the surrounding bone was found at the most coronal portion of it. The highest and lowest magnitude of stress can be seen at the top and end of screws, respectively. When oblique force was applied, the highest stress values are observed at the coronal and middle portion of the bone and screws, respectively. Overall, all of the tenting screws tested were sufficiently stable to maintain membrane volume against vertical and oblique forces.

AB - Gunn rats bear a mutation within the uridine diphosphate glucuronosyltransferase 1a1 (Ugt1a1) gene resulting in high serum bilirubin levels as seen in Crigler Najjar syndrome. In this study, the Gunn rat was used as an animal model for heritable liver dysfunction. Induced mesenchymal stem cells (iMSCs) derived from embryonic stem cells (H1) and induced pluripotent stem cells were transplanted into Gunn rats after partial hepatectomy. The iMSCs engrafted and survived in the liver for up to 2 months. The transplanted iMSCs differentiated into functional hepatocytes as evidenced by partially suppressed hyperbilirubinemia and expression of multiple human-specific hepatocyte markers such as albumin, hepatocyte nuclear factor 4alpha, UGT1A1, cytokeratin 18, bile salt export pump, multidrug resistance protein 2, Na/taurocholate-cotransporting polypeptide, and alpha-fetoprotein. These findings imply that transplanted human iMSCs can contribute to liver regeneration in vivo and thus represent a promising tool for the treatment of inherited liver diseases. PMID- 30280964 TI - In situ synthesis of bacterial cellulose/copper nanoparticles composite membranes with long-term antibacterial property. AB - Bacterial cellulose (BC), with unique structure and properties, has attracted much attention in the biomedical field, especially in using as wound dressing. However, pure BC lacks the antimicrobial activity, which limits its application in wound healing. To solve this problem, copper nanoparticles (Cu NPs) loaded BC membranes were fabricated by using in situ chemical reduction method. The morphology and chemical composition of the composite membranes were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier Transform Infrared (FTIR) and thermogravimetric analysis (TGA). The results showed that Cu NPs evenly distributed and anchored in the three-dimensional (3-D) nanofiber network of BC through physical bonding. Traces of Cu2O were observed on the membranes probably because the Cu2+ was incompletely reduced. The Cu NPs loaded BC membranes showed efficient long-term antibacterial activity against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) even after immersion in deionized water for up to 90 days. The composite membranes kept sustained release of copper ion, which may contribute to the long-term antibacterial activity. Furthermore, with controlled Cu concentration, BC/Cu membranes did not show obvious cytotoxicity to normal human dermal fibroblasts (NHDF). In all, the present results reveal that BC/Cu membranes with efficient antibacterial activity are promising to be used as wound dressings. PMID- 30280965 TI - Mnemonic emotion regulation: a three-process model. AB - Emotion regulation comprises attempts to influence when and how emotions are experienced and expressed. It has mostly been conceived of as proactive (e.g. situation selection) or reactive (e.g. attentional distraction), but it may also be retroactive and involve memory. I term such past-oriented activity mnemonic emotion regulation and propose that it involves increasing or decreasing access to or altering the characteristics of a memory. People may increase access to a memory and make it more likely that it will be retrieved in the future, for example by rehearsing a pleasant memory. They may decrease access to a memory and make it less likely that intrusions will be experienced in the future, for example by repeatedly trying to stop an unpleasant memory from being retrieved. Finally, people may alter the characteristics of a memory and change its content or context, for example by replacing a negative impression with a productive interpretation. I discuss how mnemonic emotion regulation may be instigated (e.g. via elaborate rehearsal) as well as the different motives (e.g. hedonic motives) people may have for engaging in regulation. Also, I discuss possible benefits of, variations in, and improvements of mnemonic emotion regulation. PMID- 30280966 TI - Buccal fat pad-derived stem cells in three-dimensional rehabilitation of large alveolar defects: A report of two cases. AB - This case report sought to describe efficient clinical applications of adipose- derived stem cells (AdSCs) originated from buccal fat pad (BFP) in combination with conventional guided bone regeneration as protected healing space for reconstruction of large alveolar defects after multi-impacted teeth extractions. The first case was a 19-year-old female with several impacted teeth in the maxillary and mandibular regions, which were not capable to forced erupt and recommended by the orthodontist for surgical extraction. Following this procedure, a large bone defect created and this space was filled by AdSCs loaded natural bovine bone mineral (NBBM) which protected with lateral ramus cortical plates, micro-screws and collagen membrane. After 6 months post- guided bone regeneration, she was subjected to six and seven implants placements, respectively in the maxilla and mandible. At 10 months postoperatively, radiographic evaluations revealed thorough survival of implants. The second case was a 22-year-old male with the same complain and large bony defects created after his teeth extraction. After 6 months post- guided bone regeneration, he received four dental implants in his maxilla and seven implants in the mandible. At 48 months postoperatively, radiographies showed complete survival of implants. As the result, this approach represented a considerable amount of three dimensional bone formation in both cases which enable us to utilize dental implant therapy for rehabilitation of the whole dentition. The application of AdSCs isolated from BFP in combination with NBBM can be considered as an efficient treatment for bone regeneration in large alveolar bone defects.

AB - Staphylococcus aureus is the leading cause of infective endocarditis (IE). While the role of S. aureus cell-wall associated protein clumping factor A (ClfA) in promoting IE has been already demonstrated, that of the secreted plasma-clotting factors staphylocoagulase (Coa) and von Willebrand factor-binding protein (vWbp) has not yet been elucidated. We investigated the role of Coa and vWbp in IE initiation in rats with catheter-induced aortic vegetations, using Lactococcus lactis expressing coa, vWbp, clfA or vWbp/clfA, and S. aureus Newman Deltacoa, DeltavWbp, DeltaclfA or Deltacoa/DeltavWbp/DeltaclfA mutants. vWbp-expression increased L. lactis valve infection compared to parent and coa-expressing strains (incidence: 62%, versus 0% and 13%, respectively; P < 0.01). Likewise, expression of clfA increased L. lactis infectivity (incidence: 80%), which was not further affected by co-expression of vWbp. In symmetry, deletion of the coa or vWbp genes in S. aureus did not decrease infectivity (incidence: 68 and 64%, respectively) whereas deletion of clfA did decrease valve infection (incidence: 45%; P = 0.03 versus parent), which was not further affected by the triple deletion Deltacoa/DeltavWbp/DeltaclfA (incidence: 36%; P > 0.05 versus DeltaclfA mutant). Coa does not support the initial colonization of IE (in L. lactis) without other key virulence factors and vWbp contributes to initiation of IE (in L. lactis) but is marginal in the present of ClfA. PMID- 30280968 TI - Preparation of Immunotolerant Space under the Skin and Transplantation of Islets in the Pockets. AB - A method which realizes allogeneic islets transplantation into a subcutaneous site under no immunosuppressive treatment has been desired for the treatment of type 1 diabetes. In this study, two donor-recipient combinations were employed: F344 rat donors (RT-1lv1) and ACI rat recipients (RT-1a); and Wistar rat donors (closed colony) and Lewis rat recipients (RT 1l). An agarose rod , which carried basic fibroblast growth factor (bFGF; 50 MUg/rod, agarose-bFGF rod), was implanted into each of two dorsal subcutaneous sites of a streptozotocin induced diabetic rat for 7 days, and the space was formed by removal of the rod. 1500 allogeneic islets were transplanted into each of the subcutaneous spaces. No immunosuppressive medication was given before or after islet transplantation. The immunological analyses of the granulomatous tissue formed by agarose-bFGF rod were carried out with flow cytometry and gene expression to get some information for mechanism of acceptance of allogeneic islets. Subcutaneous spaces surrounded with highly vascularized granulomatous tissue were formed by agarose-bFGF rod implantation for 7 days. All recipients demonstrated long-term nomoglycemia (>100 days) in both donor recipient combinations. The percentages of regulatory T (Treg) cells/CD4 cells in the granulomatous tissue increased by the implantation of agarose-bFGF rod and the percentages remained high after islet transplantation. In addition, expression levels of genes associated with chemotaxis and induction of Treg cells increased in the granulomatous tissue by the implantation of agarose-bFGF rod. The agarose-bFGF rod implantation is a useful method for preparation of immunotolerant site for successful allogeneic islet transplantation without immunosuppressive medication, and Treg cells might play a pivotal role in the graft acceptance. PMID- 30280969 TI - 'In the Islands people don't really talk about this stuff, so you go through life on your own': An arts-based study exploring intimate relationships with young people in Samoa. AB - This study explores conceptualisations and understandings of intimate relationships with young people in Samoa - an at-risk group experiencing high rates of intimate partner violence and alienation from sexual and relationship health promotion. Insights contribute to the immediate need to advance knowledge and practice around prevention with this group. An arts-based approach, which included a two-day interactive drama workshop coupled with follow-up, peer-led focus groups, was used to explore perceptions and understandings related to intimate relationships with 15 tertiary educated young people (nine female and six male) from across Samoa. Intersectionality informed the data collection and thematic analysis, examining participants' lived experiences and the ways multiple and intersecting identities interact within social and cultural systems to influence and inform these experiences. Outcomes highlight important tensions for young people, including the way in which age, gender, religion and sexuality interact with social hierarchies and power structures, socially prescribed gender norms, family structures and globalisation. This research provides insights that can inform the development of prevention strategies to address the root causes of intimate partner violence, building the knowledge and skills required for establishing intimate relationships free from violence with young people. PMID- 30280970 TI - Normative Interlimb Impedance Ratios: Implications for Early Diagnosis of Uni- and Bilateral, Upper and Lower Limb Lymphedema. AB - BACKGROUND: Bioimpedance spectroscopy detects unilateral lymphedema if the ratio of extracellular fluid (ECF) between arms or between legs is outside three standard deviations (SDs) of the normative mean. Detection of bilateral lymphedema, common after bilateral breast or gynecological cancer, is complicated by the unavailability of an unaffected contralateral limb. The objectives of this work were to (1) present normative values for interarm, interleg, and arm-to-leg impedance ratios of ECF and ECF normalized to intracellular fluid (ECF/ICF); (2) evaluate the influence of sex, age, and body mass index on ratios; and (3) describe the normal change in ratios within healthy individuals over time. METHODS: Data from five studies were combined to generate a normative data set (n = 808) from which mean and SD were calculated for interarm, interleg, and arm-to leg ratios of ECF and ECF/ICF. The influence of sex, age, and body mass index was evaluated using multiple linear regression, and normative change was calculated for participants with repeated measures by subtracting their lowest ratio from their highest ratio. RESULTS: Mean (SD) interarm, interleg, dominant arm-to-leg, and nondominant arm-to-leg ratios were 0.987 (0.067), 1.005 (0.072), 1.129 (0.160), and 1.165 (0.174) for ECF ratios; and 0.957 (0.188), 1.024 (0.183), 1.194 (0.453), and 1.117 (0.367) for ECF/ICF ratios, respectively. Arm-to-leg ratios were significantly affected by sex, age, and body mass index. Mean normative change ranged from 7.2% to 14.7% for ECF ratios and from 14.7% to 67.1% for ECF/ICF ratios. CONCLUSION: These findings provide the necessary platform for extending bioimpedance-based screening beyond unilateral lymphedema. PMID- 30280971 TI - Video-assisted thoracoscopic surgery for the treatment of pericardial hydatid cyst. AB - INTRODUCTION: We would like to present video-assisted thoracoscopic surgery for the treatment of pericardial hydatid cyst. PATIENT AND METHOD: Thirty two-year old female patient was referred for evaluation of a left mediastinal mass. Magnetic resonance image, computed tomography and transesophageal echocardiography confirmed a well circumscribed mass with compatible hydatid cyst at the left pericardial wall end of the differantial diagnosis. Our surgical plan entailed the endoscopic resection of pericardial hydatid cyst. We did not adopt a more precise strategy such as open procedure. We managed removal of the hydatid cyst by using video assisted thoracoscopic surgery. RESULTS: The patient has been doing well for 4 years now after her surgery. CONCLUSION: We think that endoscopic approach is an effective treatment modality for pericardial hydatid cyst. PMID- 30280972 TI - Dynamic culture substrates that mimic the topography of the epidermal-dermal junction. AB - The junction between the epidermal and dermal layers of human skin undulates, the width and depth of the undulations varying with age and disease. We previously showed that when primary human epidermal keratinocytes are seeded on collagen coated undulating static polydimethylsiloxane (PDMS) elastomer substrates, the stem cells, differentiated cells and proliferating cells become patterned in response to cues from the underlying substrate. To investigate how patterning occurs over time, we have now created a dynamic model, in which a collagen-coated PLGA membrane is placed over a polyimide sheet containing circular holes, differing in diameter and spacing. When a vacuum is applied the membrane is induced to undulate, the heights of the undulations depending on the pressure applied and the size of the holes. We observed clustering of cells with high levels of beta1 integrin expression, a stem cell marker, in the base of the undulations within 48h of applying the vacuum. Differentiating, involucrin positive cells did not cluster; however, there was clustering of cells with high E-cadherin expression and nuclear YAP. Rho kinase inhibition resulted in loss of clustering, implicating a role for Rho family members in the process. PMID- 30280973 TI - Seeding the gender revolution: Women's education and cohort fertility among the baby boom generations. AB - In Europe and the United States, women's educational attainment started to increase around the middle of the twentieth century. The expected implication was fertility decline and postponement, whereas in fact the opposite occurred. We analyse trends in the quantum of cohort fertility among the baby boom generations in 15 countries and how these relate to women's education. Over the 1901-45 cohorts, the proportion of parents with exactly two children rose steadily and homogeneity in family sizes increased. Progression to a third child and beyond declined in all the countries, continuing the ongoing trends of the fertility transition. In countries with a baby boom, and especially among women with post primary education, this was compensated for by decreasing childlessness and increasing progression to a second child. These changes, linked to earlier stages of the fertility transition, laid the foundations for later fertility patterns associated with the gender revolution. PMID- 30280974 TI - Intrathoracic hooked wire migration managed by minimally invasive thoracoscopic surgery. AB - BACKGROUND: Needle-guided localization wire is widely used to locate non-palpable breast lesion before surgery. A rare complication of this technique is wire migration. We report a case of an intrathoracic hooked wire migration in a 41 year-old female treated by video-assisted thoracoscopic surgery (VATS). METHODS: We report a recent patient history and we review the cases reported in the literature. RESULTS: Hook removal by thoracoscopy seemed to be the less invasive and most effective approach for this stable case. Even asymptomatic migration should be treated, and the device removed. The less invasive approach can be considered after estimating the risk and best possible timing. CONCLUSION: The loss of a hooked wire can lead to dramatic lesions. In every case, the device must be found or, if not, migration ruled out. The hooked wire must be removed, and the timing and the approach must be adapted to each case. VATS should be considered, in a stable patient to assess the lesions, to treat them and to remove the device. PMID- 30280975 TI - Community perceptions of obstetric fistula in Malawi. AB - It is well-documented that obstetric fistula, a severe birth injury, is caused by a prolonged obstructed labour that has not been relieved on time. Lay people often understand causation differently. This study sought to explore the awareness and local meanings attached to obstetric fistula in the rural parts of Malawi. We conducted interviews with key informants and focus group discussions with community members in purposively selected communities in the central region of Malawi. We categorised data using Nvivo 10 and conducted a thematic analysis. Findings indicate that there is considerable awareness about fistula in local communities; however, community members have very limited knowledge about its causes. Participants associated obstetric fistula with sexually transmitted diseases, the woman's laziness to push during labour, witchcraft and the husband's infidelity, which contributed to the isolation of the affected women. Strategies to eradicate obstetric fistula in general, and its social consequences in particular, should include more information on causes and prevention. This may help to dispel misconceptions about fistula, increase acceptance and support for women with fistula, and subsequently improve the quality of their lives and the lives of girls and women who may suffer from this condition in the future.

PMID- 30280980 TI - Pharmacological Stimulation of Mitochondrial Biogenesis Using the Food and Drug Administration-Approved beta2-Adrenoreceptor Agonist Formoterol for the Treatment of Spinal Cord Injury. AB - A hallmark of the progressive cascade of damage referred to as secondary spinal cord injury (SCI) is vascular disruption resulting in decreased oxygen delivery and loss of mitochondria homeostasis. While therapeutics targeting restoration of single facets of mitochondrial function have proven largely ineffective clinically post-SCI, comprehensively addressing mitochondrial function via pharmacological stimulation of mitochondrial biogenesis (MB) is an underexplored strategy. This study examined the effects of formoterol, a mitochondrial biogenic Food and Drug Administration-approved selective and potent beta2-adrenoreceptor (ADRB2) agonist, on recovery from SCI in mice. Female C57BL/6 mice underwent moderate SCI using a force-controlled impactor-induced contusion model, followed by daily formoterol intraperitoneal administration (0.1 mg/kg) beginning 1 h post SCI. The SCI resulted in decreased mitochondrial protein expression, including PGC-1alpha, in the injury and peri-injury sites as early as 3 days post-injury. Formoterol treatment attenuated this decrease in PGC-1alpha, indicating enhanced MB, and restored downstream mitochondrial protein expression to that of controls by 15 days. Formoterol-treated mice also exhibited less histological damage than vehicle-treated mice 3 days after injury-namely, decreased lesion volume and increased white and gray matter sparing in regions rostral and caudal to the injury epicenter. Importantly, locomotor capability of formoterol-treated mice was greater than vehicle-treated mice by 7 days, reaching a Basso Mouse Scale score two points greater than that of vehicle-treated SCI mice by 15 days. Interestingly, similar locomotor restoration was observed when initiation of treatment was delayed until 8 h post-injury. These data provide evidence of ADRB2 mediated MB as a therapeutic approach for the management of SCI. PMID- 30280981 TI - Exploring Cross-Sectional Predictors of Suicide Ideation, Attempt, and Risk in a Large Online Sample of Transgender and Gender Nonconforming Youth and Young Adults. AB - PURPOSE: Rates of suicide ideation and attempt appear to be particularly high in the transgender and gender nonconforming (TGNC) population, yet little is known about which factors are the most salient contributors for TGNC young people and how these contributors vary across suicide-related outcomes. METHODS: Within the largest sample of TGNC young people to date (N = 1896; ages 14-30), we examined the contribution of demographics (age, assigned sex, gender identity, sexual orientation identity, race/ethnicity, and socioeconomic status), minority stress (gender-related affirmation, gender-related self-concept, victimization, and gender-affirming medical treatment desire/access), social support (from family and friends), and depressive symptoms in the cross-sectional prediction of three suicide-related outcomes: past-year attempt, past-year ideation, and a composite measure of suicide risk. RESULTS: Each set of factors explained significant variance in each outcome; however, only several predictors remained significant in each of the full models. Gender-related victimization and depressive symptoms were independent predictors for all three outcomes. Additional predictors varied across outcome. Age, male identity, sexual orientation-based victimization, and friend support were associated with suicide attempt. Age, queer identity, gender related self-concept negativity, and family support were associated with suicide ideation, and pansexual identity and gender-related self-concept negativity were associated with positive suicide risk screen. CONCLUSION: Prevention and intervention efforts aimed at building support and positive self-concept, decreasing victimization, and treating depression are likely to partially reduce suicide ideation and attempt in TGNC adolescents and young adults. Comprehensive interventions with younger adolescents are particularly critical. PMID- 30280982 TI - Characterization of a tubular electrochemical reactor for the degradation of the commercial diuron herbicide. AB - After designing and constructing an electrochemical reactor with concentric electrodes and tangential feed (RECT), it is necessary to characterize it and to study its performance. The experimental study of the residence time distribution (RTD) was conducted for flow rates of 2.78 * 10-6 m3 s-1, 8.33 * 10-6 m3 s-1 and 13.9 * 10-6 m3 s-1. According to the values obtained from the Pe number (0.67 1.52), the RECT fits as tubular with great dispersion. The determined empirical correlation (Sh = 18.16 Re0.50 Sc0.33) showed a laminar flow behavior in the range of Reynolds number (Re) between 23 and 117. In order to use RECT in effluent treatment, an electrochemical oxidation study of the Diuron model molecule (Nortox(r)) was performed to analyze reactor performance in a closed system with total reflux. A decay kinetics of pseudo-first order was associated with the decay of the concentration of diuron and 30% mineralization in 180 min of process were obtained, having a total volume of 4 * 10-3 m3 and an initial concentration of commercial Diuron in 215.83 mg dm-3. Eleven by-products were identified by HPLC-MS analysis and, from this, it was possible to propose a route of degradation of the diuron. From these observations, it can be inferred that the studied electrochemical reactor had applicability in the degradation of recalcitrant compounds, as is the case of commercial diuron. Make some changes in the electrochemical reactor studied and other advanced oxidative processes, such as electro-Fenton, can be associated with the studied system to achieve a better conversion efficiency. PMID- 30280983 TI - What Accounts for Prosocial Behavior? Roles of Moral Identity, Moral Judgment, and Self-Efficacy Beliefs. AB - Prior research suggests that moral identity influences individuals' willingness to engage in prosocial behavior. Little attention, however, has been given to the roles of and relations between moral identity and other factors, such as moral judgment, in accounting for types of prosocial behavior in adolescence. The current study examined the extent to which moral identity, moral judgment, and social self-efficacy contribute to prosocial behaviors in adolescence. Approximately 338 adolescents (Mage = 13.4 years) completed measures of moral identity, moral judgment, social self-efficacy, and prosocial behavior. Teachers rated adolescents' prosocial behaviors, which largely corroborated the adolescents' self-reports. Moral identity was found to predict most types of prosocial behavior. Moral judgment and moral identity were related and jointly predicted altruistic prosocial behaviors, but did not predict helping in front of others. Further, moral identity mediated the relationships between moral judgment and some forms of prosocial behavior (e.g., emotional, volunteering). Self efficacy beliefs were found to predict some types of prosocial behavior (e.g., public), perhaps providing adolescents with confidence to engage in prosocial action. Overall, moral identity was especially effective in directly accounting for prosocial behavior, and may act as a mediator to bridge the moral judgment moral action gap among adolescents.

PMID- 30280985 TI - Radiation-Drug Combinations to Improve Clinical Outcomes and Reduce Normal Tissue Toxicities: Current Challenges and New Approaches: Report of the Symposium Held at the 63rd Annual Meeting of the Radiation Research Society, 15-18 October 2017; Cancun, Mexico. AB - The National Cancer Institute's (NCI) Radiation Research Program (RRP) is endeavoring to increase the relevance of preclinical research to improve outcomes of radiation therapy for cancer patients. These efforts include conducting symposia, workshops and educational sessions at annual meetings of professional societies, including the American Association of Physicists in Medicine, American Society of Radiation Oncology, Radiation Research Society (RRS), Radiosurgery Society, Society of Nuclear Medicine and Molecular Imaging, Society for Immunotherapy of Cancer and the American Association of Immunology. A symposium entitled "Radiation-Drug Combinations to Improve Clinical Outcomes and Reduce Normal Tissue Toxicities" was conducted by the NCI's RRP during the 63rd Annual Meeting of the RRS on October 16, 2017 in Cancun, Mexico. In this symposium, discussions were held to address the challenges in developing radiation-drug combinations, optimal approaches with scientific evidence to replace standard-of care, approaches to reduce normal tissue toxicities and enhance post-treatment quality-of-life and recent advances in antibody-drug conjugates. The symposium included two broad overview talks followed by two talks illustrating examples of radiation-drug combinations under development. The overview talks identified the essential preclinical infrastructure necessary to accelerate progress in the development of evidence and important challenges in the translation of drug combinations to the clinic from the laboratory. Also addressed, in the example talks (in light of the suggested guidelines and identified challenges), were the development and translation of novel antibody drug conjugates as well as repurposing of drugs to improve efficacy and reduce normal tissue toxicities. Participation among a cross section of clinicians, scientists and scholars-in training alike who work in this focused area highlighted the importance of continued discussions to identify and address complex challenges in this emerging area in radiation oncology. PMID- 30280986 TI - A Woman'S Status and Prenatal Care Utilization in Patrilocal Households of Post Soviet Countries. AB - Women's household autonomy is associated with maternal healthcare utilization in developing countries, but its effects are not consistently positive. In the current study, the researchers test prenatal care utilization in Armenia and Azerbaijan (N = 2,159). After controlling for socioeconomic factors, we find that women's autonomy seems to be a mixed blessing. For instance, participating in daily purchases delays the start of prenatal care, but results in more prenatal care visits. Additionally, a woman's household position as a daughter-in-law has significant negative associations with accessing prenatal care during the first trimester of pregnancy. PMID- 30280987 TI - Vicarious Posttraumatic Growth in End-of-Life Care: How Filling Gaps in Knowledge Can Foster Clinicians' Growth. AB - Vicarious posttraumatic growth is a term used to describe the positive benefits from working with trauma patients who themselves have experienced a highly stressful or traumatic event and resultant growth. Research on vicarious posttraumatic growth remains in its initial stages and findings are inconsistent, leading to the need for additional research. A literature review was performed to ascertain the methodologies guiding research on vicarious posttraumatic growth and identify gaps in knowledge. This study found that 71% of research studies examined used survey instruments to measure vicarious posttraumatic growth and 87% of these studies utilized the Posttraumatic Growth Inventory (alpha = 0.90). This instrument was not designed to measure secondary trauma. In order to support clinicians who are at high risk of adverse outcomes, the knowledge of vicarious posttraumatic growth must be broadened by conducting research with varying methodologies, among other populations, and by developing effective survey instruments to operationalize this concept. PMID- 30280988 TI - Egg Intake Has No Adverse Association With Blood Lipids Or Glucose In Adolescent Girls. AB - OBJECTIVE: Longitudinal data on cardiometabolic effects of egg intake during adolescence are lacking. The current analyses aim to evaluate the impact of usual adolescent egg consumption on lipid levels, fasting glucose, and insulin resistance during late adolescence (age 17-20 years). METHODS: Data from 1392 girls, aged 9 to 10 at baseline and followed for 10 years, in the National Heart, Lung, and Blood Institute's National Growth and Health Study were used to examine the association between usual egg intake alone and in combination with other healthy lifestyle factors and late adolescent lipid levels, fasting glucose, and insulin resistance, measured as homeostasis model assessment of insulin resistance (HOMA-IR). Diet was assessed using 3-day food records during eight examination cycles. Girls were classified according to usual weekly egg intake, ages 9-17 years: <1 egg/wk (n = 361), 1 to <3 eggs/wk (n = 703), and >=3 eggs/wk (n = 328). Analysis of covariance modeling was used to control for confounding by other behavioral and biological risk factors. RESULTS: Girls with low, moderate, and high egg intakes had adjusted low-density lipoprotein cholesterol levels of 99.7, 98.8, and 95.5 mg/dL, respectively (p = 0.0778). In combination with higher intakes of fiber, dairy, or fruits and vegetables, these beneficial effects were stronger and statistically significant. There was no evidence that >=3 eggs/wk had an adverse effect on lipids, glucose, or HOMA-IR. More active girls who consumed >=3 eggs/wk had the lowest levels of insulin resistance. CONCLUSION: These results suggest that eggs may be included as part of a healthy adolescent diet without adverse effects on glucose, lipid levels, or insulin resistance. PMID- 30280989 TI - Message and Delivery Preferences for Online Tobacco Education among Adolescents and Young Adults. AB - Use of cigarettes and noncigarette tobacco products (NCTPs) among adolescents and young adults remains high. Strategies to communicate the risks of cigarettes and NCTPs are needed. Online tobacco education is one such strategy; however, there is little guidance for message development. We conducted four focus groups (n = 39) with adolescent and young adult to identify message and delivery preferences for online tobacco education. Participants evaluated three existing tobacco education websites. Transcripts were coded for preferred tobacco education message content, delivery, and willingness to use online tobacco education. Participants preferred novel, concise facts, embedded links to credible sources, and an anti-industry tone for website messages. Participants expressed an aversion to message strategies that relied on scare tactics or attempted to simulate youth media trends (e.g., overuse of hashtags). To increase exposure, participants recommended using social media to drive engagement. Results serve as guidelines for what information adolescents and young adults desire, as well as how they want this information communicated with online tobacco education. Our findings - youth prefer new, fact-based information that is conveyed concisely, with sources, without authoritative tones, and delivered via social media - provides guidance for how to develop online tobacco education for this at-risk population. PMID- 30280990 TI - Large Cytologically Benign Thyroid Nodules Do Not Have High Rates of Malignancy or False-Negative Rates and Clinical Observation Should be Considered: A Meta Analysis. AB - BACKGROUND: Management of large thyroid nodules is controversial, as data are conflicting regarding overall rates of malignancy (ROM) in all nodules and frequency of false-negative fine-needle aspiration results (FNR) in cytologically benign nodules. This meta-analysis aimed to evaluate and compare ROM and FNR in small versus large nodules published in the literature. METHODS: Articles indexed in PubMed, written in English, published electronically or in print on or prior to December 8 2017 were searched for "false negative thyroid size or cm" and "malignancy rates benign thyroid nodules." Three hundred fifty-two unique citations were identified. Multiple reviewers selected a final set of 35 articles that contained nodules stratified by size (3, 4, or 5 cm), with benign or all cytologic diagnoses, and with postsurgical histologic diagnoses. Multiple observers extracted data, including numbers of total, cytologically benign, and histologically malignant nodules. Size cutoffs of 3, 4, and/or 5 cm were analyzed in 14, 24, and 1 article, respectively. RESULTS: ROM in all nodules >=3 cm (13.1%) and >=4 cm (20.9%) was lower than those <3 cm (19.6%) and <4 cm (19.9%; odds ratio [OR] = 0.72 [confidence interval (CI) 0.64-0.81] and OR = 0.85 [CI 0.77-0.95]). FNR in nodules >=3 cm (7.2%) was not different from smaller nodules (5.7%; OR = 1.47 [CI 0.80-2.69]). FNR in nodules >=4 cm (6.7%) was slightly higher than those <4 cm (4.5%; OR = 1.38 [CI 1.06-1.80]). The most frequently reported false-negative diagnosis was papillary thyroid carcinoma. CONCLUSIONS: Rates of malignancy and false-negative FNA results vary but, in most studies, are not higher in larger nodules. Patients with large, cytologically benign thyroid nodules need not undergo immediate surgical resection, as false-negative FNA rates are low and are expected to decrease in light of nomenclature revision of a subset of follicular variants of papillary thyroid carcinoma.

AB - Accurate assessment of dietary intake is essential in clinical practice and research. While energy intake (EI) misreporting has been extensively studied in the general population, relatively little is known about misreporting among older people. This cross-sectional study used clinical data routinely collected in 127 participants, aged 70-96 years, from the Toulouse Frailty Clinic. EI was assessed by diet history interview and three-day food record. Misreporters were identified with the Goldberg cut-off method, using the Harris-Benedict equation to estimate total energy expenditure. The response rate was 66% for three-day food record and 93% for diet history interviews. EI from diet history interviews (1799 +/- 416 kcal/day) was significantly higher than from food records (1400 +/- 381 kcal/day; p < 0.001) and closest to total energy expenditure (1758 +/- 437 kcal/day; (p > 0.05). Thirty percent of participants were identified as underreporters with three-day food records vs. 9% with diet history interviews. Overreporters were found with diet history interviews only (11% of participants). In older people, the diet history interview has the advantage of obtaining a higher response rate and a lower underreporting rate, compared to three-day food record. Nevertheless, with this method, overreporting was observed and interpreting results should be done with caution. PMID- 30280996 TI - From Food for Survival to Food for Personalized Optimal Health: A Historical Perspective of How Food and Nutrition Gave Rise to Nutrigenomics. AB - Human nutrition has progressed impressively from the hunter-gatherer mode to that of promising personalized nutrition for health optimization through advanced and sophisticated omics technologies. The contemporary major diseases, while having strong genetic components, do not conform to Mendelian genetics; hence, their expression/manifestation is not controlled by a single gene. Noncommunicable diseases such as obesity, cancer, type 2 diabetes mellitus, and cardiovascular disease are attributed to a series of chronic anomalies closely related to dietary, among other, environmental factors, and consistent deregulation of one or more groups of genes (polygenic). Collectively, these diseases constitute the main cause of death globally and pose tremendous financial burden on healthcare systems. Dietary interventions offer significant possibilities for cost-effective strategies to reduce risk of a series of metabolic diseases and/or improve the outcome of prognosis. In recent decades, the ability of particular nutrients to influence certain cellular functions as well as the regulation of several metabolic pathways via genomic interplay has been demonstrated. Nutrients can influence cellular responses and hence exert an effect on health parameters and outcomes. Several nutrients have been documented to extend their regulatory capacity at various levels including gene expression profile signatures' modulation. In addition, specific nutrients can modulate expression/activation of genes that encode regulatory hormones, which in turn are signaling agents strongly affecting metabolism and subsequently risk levels for certain metabolic diseases. The field of nutrigenomics attempts to revolutionize modern thinking on diet, food, and health; whether it will deliver is still an open matter of debate Key teaching points: A brief, yet comprehensive account on how food and nutrition evolved to give rise to nutrigenomics. Discusses potential of nutrigenomics for public health contribution in noncommunicable diseases. Debates credibility of nutrigenomics' commercial products versus the bio-hype in the field.

PMID- 30280998 TI - Applying the Health Belief Model to Medication Adherence: The Role of Online Health Communities and Peer Reviews. AB - Millions of Americans are living with at least one chronic disease, and while the majority has been prescribed medication to control symptoms-medication adherence is a widespread problem. Medication nonadherence varies by chronic disease, patient characteristics, and insurance coverage, and previous research has identified non-financial barriers including disease-related knowledge, health literacy and polypharmacy. However, given the increasing popularity of online health communities, little research examines the influence of user-generated content on health behaviors. Many patients use the internet to seek and share information related to prescription medications. The current study examines patients' attitudes and behavioral intentions formed (in part) by the user generated content exchanged within online health communities. Specifically, the Health Belief Model's perceived barriers and perceived benefits are explored here. Twenty members from online health communities related to arthritis are interviewed to understand how peer-to-peer communication is used in regards to medication adherence. Three themes emerged from the data, including striving for pain relief, negotiating potential side effects, and finding the new normal. Theoretical and practical implications are discussed. PMID- 30280997 TI - Use of Mental Health Services Among College Students by Sexual Orientation. AB - PURPOSE: The current study examines differences between lesbian, gay, bisexual, and questioning (LGBQ) students and heterosexual students in terms of counseling and mental health services received (healthcare utilization), from whom students would seek help, and who contributed positively to students' ability to cope during a stressful period. METHODS: An online survey was administered among 25,844 college students, enrolled in 76 schools (mean age = 25.52). The majority of participants was graduate students (42.81%) and reported their race/ethnicity as non-Hispanic White (70.49%). RESULTS: Compared with their heterosexual counterparts, gay males and lesbian/gay and bisexual females reported receiving more counseling or mental health services, most notably from counselors, therapists, psychologists, and/or social workers. Bisexual males and LGBQ females were less likely to seek help from a parent or family member compared with heterosexual males and females, respectively. Racial/ethnic minority bisexual females were less likely to seek help from a friend or roommate than non-Hispanic White bisexual females. Compared with their heterosexual counterparts, gay and questioning males and LGBQ females were more likely to report that religion reduced their ability to cope. CONCLUSION: The current findings illuminate important differences by sexual orientation in terms of seeking and receiving mental health services. Although we found that lesbian/gay and bisexual college students were more likely to receive counseling and mental healthcare, we cannot ascertain whether they were satisfied with the services they received. The findings also suggest that certain groups of LGBQ students do not find support with their clergy and family, which may indicate a lack of understanding or acceptance of LGBQ issues.

PMID- 30281000 TI - Towards Health Equity: Deaf Adults' Engagement in Social e-Health Activities and e-Communication with Health Care Providers. AB - Deaf people face significant barriers with accessing health information, health care services, and communication with their health care provider and as a result, show poorer health outcomes compared to the general population. Studies on the general population found that those who use social network sites (SNS) for health related activities were more likely to communicate with their health care provider via the Internet or email. For deaf individuals who use American Sign Language (ASL), using eHealth platforms to communicate with health care providers has the potential to navigate around communication barriers and create greater opportunity to discuss screening and treatment plans. Using national data from the HINTS-ASL survey, we explored whether engagement in social eHealth activities on SNS is linked to electronic communication with health care providers after controlling for deaf patient characteristics. Our sample for this study consisted of 515 deaf participants who reported using (social media/SNS) to read and share health information. Controlling for sociodemographic variables, participants who engaged in social eHealth activity were threefold more likely to communicate with their healthcare provider electronically. Using eHealth platforms for social health engagement demonstrates potential to reduce health inequality among deaf people. PMID- 30281002 TI - Legends in Urology.

PMID- 30281004 TI - Cystectomy for benign disease: readmission, morbidity, and complications. AB - INTRODUCTION: We sought to elucidate outcomes and risks associated with cystectomy and urinary diversion for benign urological conditions compared to malignant conditions. MATERIALS AND METHODS: We identified patients who underwent cystectomy and urinary diversion for benign and malignant diseases through the American College of Surgeons National Surgery Quality Improvement Program database for the period 2007-2015. Patients were selected for inclusion based upon their current procedure terminology and International Classification of Disease, Ninth revision codes. Primary outcome was 30 day morbidity including return to the operating room (OR); infectious, respiratory, and/or cardiovascular complications; readmission to the hospital; and mortality. Multivariable regression analyses were performed to identify associated factors. RESULTS: A total of 317 patients underwent cystectomy and urinary diversion for benign disease, and 5510 patients underwent radical cystectomy with urinary diversion for cancer. Rates of major morbidity (43.2% versus 38.6%), mortality (0.9% versus 1.9%), return to OR (5% versus 5.8%), readmission (19.7% versus 21.4%), postoperative sepsis (14.5% versus 12%), and wound complications (16.1% versus 14.2%) were similar among patients undergoing cystectomy for benign and malignant conditions. In the group with cystectomy for benign conditions, smoking (OR: 3.11) and longer operative duration (OR: 1.06) were significantly associated with increased overall morbidity. Wound complications were significantly higher in smokers (OR: 3.09) and with an ASA >= III (OR: 5.71) CONCLUSIONS: Patients undergoing cystectomy and urinary diversion for benign disease are at similar risk for 30 day morbidity and mortality as patients undergoing surgery for malignant conditions. Risk factors are identified that can potentially be targeted for morbidity reduction. PMID- 30281005 TI - Health-related quality of life after BCG or MMC induction for non-muscle invasive bladder cancer. AB - INTRODUCTION: To evaluate health-related quality of life (HRQoL) in patients with non-muscle invasive bladder cancer (NMIBC) during the induction phase of intravesical instillations with BCG or MMC. MATERIALS AND METHODS: HRQoL was measured by two questionnaires from EORTC (QLQ-C30 and QLQ-BLS24), stratifying results by gender, age and therapy at the start of the therapy (T0), at last instillation (T1) and at 3 months after T1 (T2). The persistence of QoL-related side effects after 3 months from the end of the induction cycle was evaluated. RESULTS: We enrolled 108 naive patients and 103 patients self-completed the questionnaires. Treatment was well tolerated in both groups. Side effects were reported by 46.6% of patients at T1 and 47.5% of patients at T2. QoL dropped at T1, returning to the baseline at T2. Drop of QoL was greater in the physical, role, emotional and social functioning domains and in some clinical domains as pain, fatigue and insomnia. Our stratified analysis showed that patients > 70 years have a worsening of QoL, a higher incidence of patient-reported side effects or symptoms in the BCG arm as compared to MMC arm. CONCLUSIONS: Our study shows that intravesical instillations of BCG or MMC during the induction phase might have a relevant effect on HRQoL. PMID- 30281006 TI - Assessment of practices in screening and treating women with bacteriuria. AB - INTRODUCTION: Evidence-based screening and treatment for bacteriuria is crucial to prevent increasing antibiotic resistance. The Infectious Disease Society of America (IDSA) previously released guidelines on the management of asymptomatic bacteriuria (ASB) and uncomplicated urinary tract infections (UTIs) in women. The study's objective was to assess physicians' practices in managing women with bacteriuria relative to these guideline recommendations. MATERIALS AND METHODS: Cross-sectional data from physicians were collected using an anonymous questionnaire. Multivariable logistic regression analyses identified independent predictors of adherence to guidelines. RESULTS: Data were collected from 260 physicians. Over half of physicians surveyed were unfamiliar with IDSA guidelines and overtreat ASB. Variables independently associated with overtreatment of ASB included a non-academic practice and practicing as an OBGYN. Nearly one third (30.1%) of physicians reported prescribing an antibiotic other than a recommended first-line agent for uncomplicated cystitis. Relative to internists, OBGYNs and urologists were more likely to prescribe a recommended first-line agent to women with uncomplicated cystitis. Of those who correctly selected a first-line agent, 29.8% prescribed a longer than recommended duration of therapy. IDSA guideline awareness was not associated with physicians' practices in managing women with bacteriuria. CONCLUSIONS: Most physicians surveyed were unfamiliar with guidelines related to managing ASB and uncomplicated UTIs in women, likely contributing to overscreening and overtreatment of ASB and the use of inappropriate antibiotic regimens in treating uncomplicated cystitis. However, optimal antibiotic prescribing was not associated with knowledge of IDSA guidelines, suggesting that guideline dissemination alone may not alter practice patterns among physicians managing women with bacteriuria. PMID- 30281007 TI - Nephrostomy tube placement prior to percutaneous nephrolithotomy does not impact outcomes. AB - INTRODUCTION: This study aims to compare outcomes of percutaneous nephrolithotomy (PCNL) performed with a nephrostomy tube placed prior to surgery versus access at the time of surgery. MATERIALS AND METHODS: Between March 2005 and August 2014, 233 PCNLs were performed. One hundred and nine of those cases underwent placement of nephrostomy tubes at least 1 day prior to surgery (Group A), and the remaining 124 cases were performed in which access was obtained at the time of PCNL (Group B). Patient demographics, comorbidities, stone size, sepsis rates, and additional complication rates including bleeding and inability to access stone were compared. RESULTS: There were no significant differences in patient demographics, stone size, or comorbidities when comparing the two groups. Success rates were not significantly different, 92.7% in Group A compared to 94.4% in Group B. Similarly, there was no significant difference in complication rates or ICU admissions. The rate of sepsis in Group A was 1.83% compared to 2.42% in Group B, which showed no statistical significance. Notably, there were more patients with neurogenic bladders in the pre-placement group (p = 0.05). CONCLUSION: Pre placement of a nephrostomy tube prior to PCNL did not result in a decreased incidence of complications or sepsis and did not demonstrate increased success rates. Patients with neurogenic bladders may be more vulnerable to suffering from sepsis and therefore role of timing of nephrostomy tube placement must be further studied. PMID- 30281008 TI - Laparoscopic heminephrectomy for duplex system: observed difference in outcomes between upper and lower pole resections. AB - INTRODUCTION: Renal duplication is a relatively common congenital abnormality of the urinary tract, but symptomatic duplex kidney is a rare presentation in adults. Traditionally, the treatment of choice for poorly functioning moiety has been heminephrectomy. There is extensive literature detailing the outcomes of minimally invasive upper pole heminephrectomy, but comparatively little published regarding lower pole resection, especially in adult patients. We present a series of 13 patients who underwent minimally invasive heminephrectomy for duplex kidney. MATERIALS AND METHODS: Over a 6 year period (2011-2017) 13 patients at a single center underwent laparoscopic heminephrectomy for symptomatic duplex kidney with a poorly functioning moiety. A retrospective review of case notes and imaging was undertaken. RESULTS: Eight and 5 patients underwent upper and lower pole heminephrectomies, respectively. Laparoscopic transperitoneal approach was utilized in all cases. Median length of stay was 2 days (range 1 to 16 days). In the upper pole cohort, one patient had a postoperative infection requiring IV antibiotics. In the lower pole cohort by contrast, there were three major complications (60%). Conversion to complete nephrectomy was necessary in one case; one patient had urinary leakage requiring selective embolization and one patient required a second operation to resect remnant calyces. Furthermore, two patients (40%) developed late recurrence of symptoms. CONCLUSIONS: Symptomatic duplex kidney is a rare presentation in adults. In our experience, heminephrectomy for non-functioning renal unit is safe and reproducible in experienced hands with no major complications and resolution of symptoms in the majority of patients. We have, however, observed a higher complication rate in those undergoing resection of a lower pole moiety. Alternative management such as uretero-ureterostomy should be considered in these cases. PMID- 30281009 TI - Impact of diabetes and metformin use on prostate cancer outcome of patients treated with radiation therapy: results from a large institutional database. AB - INTRODUCTION: Conflicting data exists on the influence of metformin on prostate cancer. We investigated the importance of metformin in patients treated with radiotherapy or brachytherapy. MATERIALS AND METHODS: All patients from a large institutionalized database, treated for primary localized prostate cancer with either brachytherapy or external-beam radiotherapy +/- androgen deprivation therapy were identified. Groups were compared by Kaplan-Meier analyses and Cox regression models. Multivariate analysis was adjusted for CAPRA-Score, type of treatment and age. RESULTS: A total of 2441 patients with complete data was identified. Among the 382 patients (16% of total) were diabetic. Two-hundred and eighty-one of the 382 diabetics (74%) were treated with metformin and 101 were treated with other anti-diabetic medication. Median follow up was 48 months (interquartile range [IQR] 24-84). Two-hundred eighteen patients (9%) died and 150 (6%) experienced biochemical recurrence (BCR). On unadjusted univariate analysis for BCR-free survival, metformin users showed a 50% reduction in BCR compared to non-metformin users. The results remained significant on multivariate analysis comparing diabetic metformin users to non-metformin users (diabetics and non-diabetics combined) (hazard ratio [HR] 0.5-0.6, p = 0.03-0.04) but lost its significance when adjusting for cancer aggressiveness. On multivariate analysis, diabetics had worse overall survival (OS) than non-diabetics (HR 1.5, 95% confidence interval [CI] 1.08-2.06, p = 0.01), but diabetics on metformin fared better than diabetics not taking metformin (HR 0.5, 95% CI 0.26-0.86, p = 0.01). CONCLUSION: Metformin use in this analysis appears to be associated with better BCR and OS. Larger datasets and prospective trials are warranted to validate these results. PMID- 30281010 TI - Survival and secondary interventions following treatment for locally-advanced prostate cancer. AB - INTRODUCTION: The utility of radical prostatectomy (RP) for locally-advanced prostate cancer remains unknown. Retrospective data has shown equivalent oncologic outcomes compared to radiation therapy (RT). RP may provide local tumor control and prevent secondary interventions from local invasion, and may decrease costs. MATERIALS AND METHODS: Using SEER-Medicare data from 1995-2011 we identified men with locally-advanced prostate cancer undergoing RP or RT. Rates of post-treatment diagnoses and interventions were identified using ICD-9 and CPT codes. Skeletal related events (SRE), androgen deprivation therapy (ADT) utilization, all-cause mortality, prostate cancer-specific mortality, and costs were compared. RESULTS: A total of 8367 men with locally-advanced prostate cancer were identified (6200 RP, 2167 RT). RT was associated with increased urinary obstruction, hematuria, infection, and cystoscopic intervention while RP was associated with increased urethral stricture intervention and erectile dysfunction. Compared to RT, RP was associated with decreased all-cause mortality (3.1 versus 5.2 deaths/100-person-years, p < 0.001), prostate cancer-specific mortality (0.8 versus 2.0 deaths/100-person-years, p < 0.001), SREs (2.0 versus 3.4 events/100 person-years, p < 0.001), and ADT utilization overall (7.4 versus 33.8 doses/100-person-years, p < 0.001) and > 3 years after treatment (3.6 versus 4.6 doses/100-person-years, p < 0.001). Overall and cancer specific costs were significantly lower for RP versus RT. CONCLUSIONS: RT for locally-advanced prostate cancer has a higher incidence of mortality, secondary diagnoses and interventions, SRE, and ADT utilization compared to RP. This may lead to increased costs and have implications for quality of life. Our findings support the utility of RP in appropriately selected men with locally-advanced prostate cancer given the possible decreased morbidity and survival benefit. PMID- 30281011 TI - Ileal perforation in the setting of atezolizumab immunotherapy for advanced bladder cancer. AB - Atezolizumab is a promising immunotherapy for advanced urothelial carcinoma. Like other immune checkpoint inhibitors, it can produce rare immune-related adverse events (IRAEs). Here we present the recent case of a patient with metastatic bladder cancer who developed diarrhea and abdominal pain months after beginning atezolizumab therapy. He presented to our institution with an ileal perforation secondary to atezolizumab-induced enterocolitis. After surgical repair, the patient's condition improved, and he was discharged. We discuss the management of atezolizumab-induced enterocolitis, including the importance of early recognition and intervention to prevent more devastating complications. PMID- 30281012 TI - Epithelioid angiomyolipoma metastasis to the rectus abdominis. AB - A 37-year-old female presented with abdominal pain. An abdominal computed tomography scan demonstrated a 10 cm x 13 cm left renal mass. An open adrenal sparing radical nephrectomy was performed. The pathological diagnosis was epithelioid angiomyolipoma. Five-year surveillance did not demonstrate recurrence of disease. However, a 1.8 cm x 2.5 cm mass on the rectus abdominis muscle was identified after 5 years. Biopsy of the mass demonstrated histologic findings consistent with the primary tumor. Herein, we report a case of metastatic renal epithelioid angiomyolipoma to the rectus abdominis muscle more than 5 years after resection of primary renal tumor.

AB - A 26-year-old male with a personal history of schizophrenia initially presented with a 13 cm pelvic mass corresponding to a cryptorchidic testis. The patient was treated with primary and second-line chemotherapy for metastatic germ-cell tumor followed by surgical consolidation. Final pathology revealed a primitive neuroectodermal tumor (PNET) mixed with mature teratoma. Despite multidisciplinary management, significant patient non-compliance led to inadequate follow up and treatment delays ultimately resulting in death. To our knowledge, this is the only reported case of teratoma with malignant transformation arising from an untreated congenital undescended testicle.

PMID- 30281016 TI - Megasphaera stantonii sp. nov., a butyrate-producing bacterium isolated from the cecum of a healthy chicken. AB - A novel mesophilic, anaerobic, Gram-stain-negative bacterium was isolated from the cecum of a healthy white leghorn chicken, and designated AJH120T. Cells were coccoid or diplococcoid with an average size of 0.8-1.8 um and were non-motile with no evidence of spores. Phylogenetic analysis of 16S rRNA gene sequences revealed this organism to be a member of the genus Megasphaera, with the closest relatives being Megasphaera elsdenii (95 % sequence identity) and Megasphaera cerevisiae (95 % sequence identity). Growth was observed between 30 and 50 degrees C and between pH 5.0 and 9.0. AJH120T utilized a variety of carbon sources, including succinate, gluconate, fructose, ribose and pyruvate, as well as many individual amino acids. The DNA G+C content for the genome sequence of AJH120T was 52.1 mol%. Digital DNA-DNA hybridization (dDDH), average nucleotide identity (ANI) and average amino acid identity (AAI) between AJH120T and close taxonomic relatives, indicated divergence consistent with the strain representing a novel species. The major fatty acid methyl esters of the organism were C12 : 0, C14 : 0 3-OH, C18 : 1omega9c, C16 : 0 and C16 : 1omega9c. AJH120T was able to produce several short chain fatty acids, including butyrate, acetate, propionate and isovalerate. Together, these data indicate that AJH120T represents a novel species within the genus Megasphaera. We propose the name Megasphaerastantonii sp. nov. for the species. The type strain of this species is AJH120T (=DSM 106750T=CCUG 71842T). PMID- 30281017 TI - Yeast Ded1 promotes 48S translation pre-initiation complex assembly in an mRNA specific and eIF4F-dependent manner. AB - DEAD-box RNA helicase Ded1 is thought to resolve secondary structures in mRNA 5' untranslated regions (5'-UTRs) that impede 48S preinitiation complex (PIC) formation at the initiation codon. We reconstituted Ded1 acceleration of 48S PIC assembly on native mRNAs in a pure system, and recapitulated increased Ded1 dependence of mRNAs that are Ded1-hyperdependent in vivo. Stem-loop (SL) structures in 5'-UTRs of native and synthetic mRNAs increased the Ded1 requirement to overcome their intrinsically low rates of 48S PIC recruitment. Ded1 acceleration of 48S assembly was greater in the presence of eIF4F, and domains mediating one or more Ded1 interactions with eIF4G or helicase eIF4A were required for efficient recruitment of all mRNAs; however, the relative importance of particular Ded1 and eIF4G domains were distinct for each mRNA. Our results account for the Ded1 hyper-dependence of mRNAs with structure-prone 5'-UTRs, and implicate an eIF4E.eIF4G.eIF4A.Ded1 complex in accelerating 48S PIC assembly on native mRNAs. PMID- 30281018 TI - Genetic basis for coordination of meiosis and sexual structure maturation in Cryptococcus neoformans. AB - In the human fungal pathogen Cryptococcus neoformans, sex can benefit its pathogenicity through production of meiospores, which are believed to offer both physical and meiosis-created lineage advantages for its infections. Cryptococcus sporulation occurs following two parallel events, meiosis and differentiation of the basidium, the characteristic sexual structure of the basidiomycetes. However, the circuit integrating these events to ensure subsequent sporulation is unclear. Here, we show the spatiotemporal coordination of meiosis and basidial maturation by visualizing event-specific molecules in developing basidia defined by a quantitative approach. Monitoring of gene induction timing together with genetic analysis reveals co-regulation of the coordinated events by a shared regulatory program. Two RRM family regulators, Csa1 and Csa2, are crucial components that bridge meiosis and basidial maturation, further determining sporulation. We propose that the regulatory coordination of meiosis and basidial development serves as a determinant underlying the production of infectious meiospores in C. neoformans. PMID- 30281019 TI - Visualization of the type III secretion mediated Salmonella-host cell interface using cryo-electron tomography. AB - Many important gram-negative bacterial pathogens use highly sophisticated type III protein secretion systems (T3SSs) to establish complex host-pathogen interactions. Bacterial-host cell contact triggers the activation of the T3SS and the subsequent insertion of a translocon pore into the target cell membrane, which serves as a conduit for the passage of effector proteins. Therefore the initial interaction between T3SS-bearing bacteria and host cells is the critical step in the deployment of the protein secretion machine, yet this process remains poorly understood. Here, we use high-throughput cryo-electron tomography (cryo ET) to visualize the T3SS-mediated Salmonella-host cell interface. Our analysis reveals the intact translocon at an unprecedented level of resolution, its deployment in the host cell membrane, and the establishment of an intimate association between the bacteria and the target cells, which is essential for effector translocation. Our studies provide critical data supporting the long postulated direct injection model for effector translocation. PMID- 30281020 TI - Medial orbitofrontal inactivation does not affect economic choice. AB - How are decisions made between different goods? One theory spanning several fields of neuroscience proposes that their values are distilled to a single common neural currency, the calculation of which allows for rational decisions. The orbitofrontal cortex (OFC) is thought to play a critical role in this process, based on the presence of neural correlates of economic value in lateral OFC in monkeys and medial OFC in humans. We previously inactivated lateral OFC in rats without affecting economic choice behavior. Here we inactivated medial OFC in the same task, again without effect. Behavior in the same rats was disrupted by inactivation during progressive ratio responding previously shown to depend on medial OFC, demonstrating the efficacy of the inactivation. These results indicate that medial OFC is not necessary for economic choice, bolstering the proposal that classic economic choice is likely mediated by multiple, overlapping neural circuits. PMID- 30281021 TI - Changes in mRNA abundance drive shuttling of RNA binding proteins, linking cytoplasmic RNA degradation to transcription. AB - Alterations in global mRNA decay broadly impact multiple stages of gene expression, although signals that connect these processes are incompletely defined. Here, we used tandem mass tag labeling coupled with mass spectrometry to reveal that changing the mRNA decay landscape, as frequently occurs during viral infection, results in subcellular redistribution of RNA binding proteins (RBPs) in human cells. Accelerating Xrn1-dependent mRNA decay through expression of a gammaherpesviral endonuclease drove nuclear translocation of many RBPs, including poly(A) tail-associated proteins. Conversely, cells lacking Xrn1 exhibited changes in the localization or abundance of numerous factors linked to mRNA turnover. Using these data, we uncovered a new role for relocalized cytoplasmic poly(A) binding protein in repressing recruitment of TATA binding protein and RNA polymerase II to promoters. Collectively, our results show that changes in cytoplasmic mRNA decay can directly impact protein localization, providing a mechanism to connect seemingly distal stages of gene expression. PMID- 30281022 TI - Differing isoforms of the cobalamin binding photoreceptor AerR oppositely regulate photosystem expression. AB - Phototrophic microorganisms adjust photosystem synthesis in response to changes in light intensity and wavelength. A variety of different photoreceptors regulate this process. Purple photosynthetic bacteria synthesize a novel photoreceptor AerR that uses cobalamin (B12) as a blue-light absorbing chromophore to control photosystem synthesis. AerR directly interacts with the redox responding transcription factor CrtJ, affecting CrtJ's interaction with photosystem promoters. In this study, we show that AerR is translated as two isoforms that differ by 41 amino acids at the amino terminus. The ratio of these isoforms was affected by light and cell growth phase with the long variant predominating during photosynthetic exponential growth and the short variant predominating in dark conditions and/or stationary phase. Pigmentation and transcriptomic analyses show that the short AerR variant represses, while long variant activates, photosynthesis genes. The long form of AerR also activates many genes involved in cellular metabolism and motility. PMID- 30281023 TI - Fusion surface structure, function, and dynamics of gamete fusogen HAP2. AB - HAP2 is a class II gamete fusogen in many eukaryotic kingdoms. A crystal structure of Chlamydomonas HAP2 shows a trimeric fusion state. Domains D1, D2.1 and D2.2 line the 3-fold axis; D3 and a stem pack against the outer surface. Surprisingly, hydrogen-deuterium exchange shows that surfaces of D1, D2.2 and D3 closest to the 3-fold axis are more dynamic than exposed surfaces. Three fusion helices in the fusion loops of each monomer expose hydrophobic residues at the trimer apex that are splayed from the 3-fold axis, leaving a solvent-filled cavity between the fusion loops in each monomer. At the base of the two fusion loops, Arg185 docks in a carbonyl cage. Comparisons to other structures, dynamics, and the greater effect on Chlamydomonas gamete fusion of mutation of axis-proximal than axis-distal fusion helices suggest that the apical portion of each monomer could tilt toward the 3-fold axis with merger of the fusion helices into a common fusion surface.

AB - BACKGROUND: Increased insulin resistance (IR), associated with specific antiretroviral drugs or drug classes, is an established risk factor for type 2 diabetes in HIV patients, ultimately increasing morbidity and mortality. To date, data on the risk of IR in tenofovir alafenamide (TAF)-based protocols are unavailable. METHODS: This prospective randomized, open-label study evaluated the effects of IR on 30 healthy volunteers receiving fixed-dose combinations (FDCs) of emtricitabine/tenofovir alafenamide (F/TAF), elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) or rilpivirine/emtricitabine/tenofovir alafenamide (R/F/TAF). IR was measured before and after 14-day treatments using the hyperinsulinemic-euglycaemic clamp technique (HEGC). Changes in IR in each group were evaluated using the mean glucose disposal rate, normalized with body weight (MBW [mg glucose/(min*kg)]). RESULTS: A total of 30 subjects underwent randomization: one subject in the F/TAF arm withdrew consent after randomization and one in the R/F/TAF arm had to be excluded because of technical failure during HEGC, resulting in 28 subjects in the per-protocol population (F/TAF, n=9 subjects; E/C/F/TAF, n=10 subjects; R/F/TAF n=9 subjects). No significant differences were detected on the baseline characteristics. IR did not differ among the groups before treatment. None of the studied antiretroviral combinations resulted in a significant change in IR after 14 days compared with baseline values, as measured by MBW (F/TAF, 11.42 +/-3.04 mean [+/-sd] versus 11.43 +/-3.23, P=0.49; E/C/F/TAF, 10.04 +/-2.49 versus 10.95 +/-4.26, P=0.30; R/F/TAF, 11.03 +/-1.96 versus 13.01 +/-4.11, P=0.13). CONCLUSIONS: Short-term treatment for F/TAF, E/C/F/TAF or R/F/TAF did not increase IR in healthy male volunteers. PMID- 30281026 TI - Cystic fibrosis survival: the changing epidemiology. AB - PURPOSE OF REVIEW: Tracking patient outcomes using cystic fibrosis (CF) national data registries, we have seen a dramatic improvement in patient survival. As there are multiple ways to measure survival, it is important for readers to understand these different metrics in order to clearly translate this information to patients and their families. The aims of this review were to describe measures of survival and to review the recent literature pertaining to survival in CF to capture the changing epidemiology. RECENT FINDINGS: Although survival has improved on a population level, several individual factors continue to impact survival such as sex, age of diagnosis, ethnic background and lung function. Survival estimates, conditional on surviving to a specified age, are more relevant to individuals living with CF today and are higher than the reported overall median age of survival. There is some evidence to suggest that newborn screening (NBS) has resulted in prolonged survival in CF. SUMMARY: Prognosis in CF is often described by reporting the median age of survival, the median age of death, the median survival conditional on living to a certain age and the survival by birth cohort. Each of these metrics provide useful information depending on an individual's personal disease trajectory. The median age of survival continues to increase in CF in many countries while mortality rates are decreasing. Several factors have been associated with worse survival such as female sex, ethnicity, worse nutritional status, lower lung function and microbiology. When comparing survival between countries, one needs to ensure that similar data collection and processing techniques are used to ensure valid and robust comparisons. PMID- 30281027 TI - Effectiveness of Cognitive Behavioral Therapy for Depression and Anxiety in Patients With Cardiovascular Disease: A Systematic Review and Meta-Analysis. AB - OBJECTIVE: Depression and anxiety are highly prevalent in patients with cardiovascular disease (CVD) and influence their mental well-being and CVD prognosis. The primary objective was to assess the effectiveness of cognitive behavioral therapy (CBT) for depression and anxiety in patients with CVD. Secondary objectives were to assess the impact of CBT on cardiovascular mortality, cardiovascular events, patient satisfaction, and quality of life. METHODS: MEDLINE, PsycINFO, CINAHL, CENTRAL, and alternative sources were searched for randomized controlled trials and observational studies with a control. Studies were required to assess CBT in coronary heart disease, acute coronary syndrome, atrial fibrillation, or postmyocardial infarction patients, with anxiety and/or depression. Studies were independently screened by two reviewers and critically appraised using the Cochrane Risk of Bias tool. The random-effects model was used to pool standardized mean differences (SMD). RESULTS: Twelve randomized controlled trials were included. At follow-up, depression (SMD = -0.35, 95% confidence interval [CI] = -0.52 to -0.17, p < .001, I = 59%) and anxiety (SMD = -0.34, 95% CI = -0.65 to -0.03, p = .03, I = 71%) scores were significantly lower in CBT patients compared with controls. Change in mental health quality of life (SF-12) was also significantly greater for CBT patients, compared with controls (mean difference = 3.62, 95% CI = 0.22 to 7.02, p = .04, I = 0%). No differences in patient satisfaction or cardiovascular events were evident between CBT and control groups. Among the study reports included in this meta-analysis, data specific to cardiovascular mortality were not reported. CONCLUSIONS: Cognitive behavioral therapy seems to be an effective treatment for reducing depression and anxiety in patients with CVD and should be considered in standard clinical care. PMID- 30281028 TI - Chronic Family Stress and Adolescent Health: The Moderating Role of Emotion Regulation. AB - OBJECTIVE: The aim of the study was to assess whether the association between chronic family stress and physiological measures is moderated by emotion regulation strategies in an adolescent sample. METHODS: Chronic family stress was assessed via a semistructured interview and emotion regulation strategies (cognitive reappraisal and suppression) via questionnaire among 261 adolescents (14.57 (1.07) years). Several metabolic (waist-hip ratio, systolic and diastolic blood pressure) and inflammatory markers (basal and stimulated proinflammatory cytokine production in response to bacterial challenge) as well as glucocorticoid sensitivity were assessed. RESULTS: There were no main effects of chronic family stress, cognitive reappraisal, or suppression on physiological measures (all p's > .10). Emotion regulation moderated the association between chronic family stress and physiological measures. As chronic family stress increased, adolescents higher in cognitive reappraisal had smaller waist-hip ratios (B = .003, SE = .001, p = .015) and lower systolic blood pressure (B = -.303, SE = .143, p = .035), although no moderation was found with respect to inflammatory markers and glucocorticoid sensitivity (all p's > .30). In addition, as chronic family stress increased, adolescents higher in suppression showed evidence of higher stimulated proinflammatory cytokine production (B = .046, SE = .020, p = .021) and lower glucocorticoid sensitivity (B = .051, SE = .021, p = .015), although basal inflammation and metabolic measures were not moderated by suppression (all p's > .50). CONCLUSIONS: This study suggests that the types of emotion regulation strategies used by adolescents may affect the extent to which chronic family stress affects important metabolic and immune processes. PMID- 30281024 TI - Bid maintains mitochondrial cristae structure and function and protects against cardiac disease in an integrative genomics study. AB - Bcl-2 family proteins reorganize mitochondrial membranes during apoptosis, to form pores and rearrange cristae. In vitro and in vivo analysis integrated with human genetics reveals a novel homeostatic mitochondrial function for Bcl-2 family protein Bid. Loss of full-length Bid results in apoptosis-independent, irregular cristae with decreased respiration. Bid-/- mice display stress-induced myocardial dysfunction and damage. A gene-based approach applied to a biobank, validated in two independent GWAS studies, reveals that decreased genetically determined BID expression associates with myocardial infarction (MI) susceptibility. Patients in the bottom 5% of the expression distribution exhibit >4 fold increased MI risk. Carrier status with nonsynonymous variation in Bid's membrane binding domain, BidM148T, associates with MI predisposition. Furthermore, Bid but not BidM148T associates with Mcl-1Matrix, previously implicated in cristae stability; decreased MCL-1 expression associates with MI. Our results identify a role for Bid in homeostatic mitochondrial cristae reorganization, that we link to human cardiac disease. PMID- 30281029 TI - Ocular myasthenia gravis: an update on diagnosis and treatment. AB - PURPOSE OF REVIEW: Myasthenia gravis is an autoimmune disease that commonly affects the palpebral and extraocular muscles. Ocular myasthenia gravis (OMG) is a variant of the disease that is confined to the ocular muscles but frequently becomes generalized over time. The diagnosis of OMG is often challenging but both clinical and laboratory findings are helpful in confirming the clinical suspicion. This review provides an update on the diagnostic approach and therapeutic options for OMG. RECENT FINDINGS: Antimuscle-specific tyrosine kinase and LDL-related receptor-related protein 4 are newly available serologic testing for myasthenia gravis that can help in increasing the diagnostic sensitivity of OMG. They should be included to the diagnostic algorithm of OMG in appropriate clinical situations. SUMMARY: OMG remains a primarily clinical diagnosis, but recent advances in laboratory testing can improve the diagnostic accuracy and should be used in appropriate clinical settings. The mainstay of treatment for OMG has not significantly changed over the past years, but the increasing availability of steroid-sparing agents improved the disease control while minimizing steroid-induced complications. PMID- 30281030 TI - Myelin oligodendrocyte glycoprotein-IgG-associated optic neuritis. AB - PURPOSE OF REVIEW: Myelin oligodendrocyte glycoprotein (MOG)-IgG-associated optic neuritis has been established as a new entity of optic neuropathy. We will review recent advances in pathophysiology, diagnosis, and clinical manifestations of MOG IgG-associated optic neuritis to better understand its distinctive characteristics. RECENT FINDINGS: MOG is expressed on the surface of myelin sheaths and oligodendrocytes. MOG is highly immunogenic and is a potential target of inflammatory demyelinating disease. MOG-IgG activate immune responses and cause demyelination without astrocytopathy. MOG-IgG are measured by cell-based assays, which have higher sensitivity and specificity than ELISA. Patients with MOG-IgG-associated optic neuritis present with initially severe vision loss, are more likely to have optic disc edema, but have favorable visual outcomes. Furthermore, patients with MOG-IgG-associated optic neuritis have higher rates of recurrence compared with MOG-IgG seronegative patients. MOG-IgG-associated optic neuritis responds well to steroid treatment, however, close monitoring for signs of relapse and long-term immunosuppression may be necessary. SUMMARY: MOG-IgG associated optic neuritis demonstrates distinctive pathophysiological and clinical characteristics from optic neuritis in aquaporin4-IgG seropositive or multiple sclerosis patients. Measurements of MOG-IgG titers by cell-based assays will be helpful for the diagnosis and treatment of optic neuritis. PMID- 30281031 TI - Ocular manifestations of cytomegalovirus in immunocompetent hosts. AB - PURPOSE OF REVIEW: This review highlights recent studies that have increasingly implicated cytomegalovirus (CMV) as a significant cause of keratouveitis and retinitis in immunocompetent hosts. RECENT FINDINGS: Molecular testing has identified that CMV infection is frequently present in cases of Posner-Schlossman and Fuchs, keratouveitis syndromes previously presumed to be idiopathic conditions. Ocular hypertension and endothelial cell loss are important complications of CMV keratouveitis and are likely mediated by viral invasion of the trabecular meshwork and corneal endothelium. Topical ganciclovir is a well tolerated, effective, and economical therapy. CMV retinitis is possible in the absence of HIV/AIDS. SUMMARY: CMV has long been considered an innocuous infection in the general population, though recent studies have found otherwise. Intraocular reactivation, replication, and invasion of the trabecular meshwork and endothelium lead to recurrent bouts of ocular hypertension and endothelial cell loss, the complications of which may be tempered with initiation of antivirals. Topical ganciclovir is a promising therapy that needs investigation. CMV retinitis, an entity previously believed isolated to the severely immunosuppressed population, has been reported on numerous occasions in presumably immunocompetent individuals, particularly following local steroid injections. Further studies may elucidate the pathogenesis of CMV in immunocompetent populations. PMID- 30281032 TI - Multimodal imaging of diabetic retinopathy. AB - PURPOSE OF REVIEW: Diabetic retinopathy is the most common microvascular complication of diabetes mellitus and a leading cause of blindness throughout the world. Ocular imaging continues to play a vital role in the diagnosis, management and monitoring of diabetic retinopathy. Major technological advancements in imaging over the past decade have improved our understanding and knowledge of diabetic retinopathy and therefore a multimodal approach to imaging has become the standard of care. RECENT FINDINGS: Updates to traditional technologies such as digital fundus photography along with recent advancements in optical coherence tomography (OCT) and OCT angiography (OCTA) have provided clinicians with new information and improved efficiency. SUMMARY: In this review, we describe the benefits and clinical applications of several imaging techniques in diabetic retinopathy including color photography, fluorescein angiography, OCT, OCTA and adaptive optics. Understanding the indications and limitations of each technology allows clinicians to gain the most information from each modality and thereby optimize patient care. PMID- 30281033 TI - Next-generation sequencing-based minimal residual disease monitoring in patients receiving allogeneic hematopoietic stem cell transplantation for acute myeloid leukemia or myelodysplastic syndrome. AB - PURPOSE OF REVIEW: The monitoring of minimal residual disease (MRD) has important clinical implications in both the pre and postallogeneic stem cell transplant (SCT) setting in acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). Next-generation sequencing (NGS) is a rapidly improving technology whose application to the monitoring of MRD is an active area of research. We aim to describe existing methods of MRD in AML and MDS, with a focus on the utility of NGS in patients undergoing SCT. RECENT FINDINGS: Flow cytometry and quantitative PCR have been recommended by the European Leukemia Net as the preferred methods of MRD in AML and MDS, but these methods have limitations in cases without a disease-defining phenotype and genotype. Clinical trials are currently ongoing to assess the use of NGS in the setting of SCT for MDS and AML. Few studies have so far assessed the optimal method of MRD monitoring in the posttransplant setting. SUMMARY: The optimal method for the monitoring of MRD in AML and MDS both pre and post transplant may require more than one technology. NGS holds great promise for the monitoring of MRD, with prospective trials currently ongoing to evaluate its efficacy in this regard. PMID- 30281034 TI - When might transferrin, hemopexin or haptoglobin administration be of benefit following the transfusion of red blood cells? AB - PURPOSE OF REVIEW: After transfusion, a percentage of red blood cells undergo hemolysis within macrophages. Intravascular exposures to hemin and hemoglobin (Hb) can occur after storage bag hemolysis, some transfusion reactions, during use of medical assist devices and in response to bacterial hemolysins. Proteins that regulate iron, hemin and Hb either become saturated after iron excess (transferrin, Tf) or depleted after hemin (hemopexin, Hpx) and Hb (haptoglobin, Hp) excess. Protein saturation or stoichiometric imbalance created by transfusion increases exposure to non-Tf bound iron, hemin and Hb. Tf, Hpx and Hp are being developed for hematological disorders where iron, hemin and Hb contribute to pathophysiology. However, complexed to their ligands, each represents a potential iron source for pathogens, which may complicate the use of these proteins. RECENT FINDINGS: Erythrophagocytosis by macrophages and processes of cell death that lead to reactive iron exposure are increasingly described. In addition, the effects of transfusion introduced circulatory hemin and Hb are described in the literature, particularly following large volume transfusion, infection and during concomitant medical device use. SUMMARY: Supplementation with Tf, Hpx and Hp suggests therapeutic potential in conditions of extravascular/intravascular hemolysis. However, their administration following transfusion may require careful assessment of concomitant disease. PMID- 30281035 TI - To transfuse or not transfuse: an intensive appraisal of red blood cell transfusions in the ICU. AB - PURPOSE OF REVIEW: This review is a critical appraisal of the current data comparing restrictive vs. liberal transfusion strategies for patients who are critically ill in ICUs. We focus on four subsets of critically ill patients: pediatric patients, patients with gastrointestinal bleeds, septic patients and patients undergoing cardiac surgery. RECENT FINDINGS: Almost a decade after the TRICC trial, a randomized trial showing the safety of a restrictive transfusion threshold in critically ill patients, four large randomized controlled trials have shown that a restrictive transfusion strategy is safe in pediatric critically ill patients, patients with acute upper gastrointestinal bleeds, patients with septic shock and patients undergoing cardiac surgery. A large multicenter randomized trial is underway to determine the safety of a restrictive strategy in myocardial infarction. SUMMARY: A restrictive transfusion threshold is recommended in nearly all critically ill patients. This is at least noninferior to more liberal transfusion practice; in addition, a restrictive threshold has shown improved outcomes in some patients and decreased chances of adverse events in patients. Judicious use of red cells improves patient outcome and protects the blood supply, a limited resource. More data are needed to determine appropriate transfusion threshold recommendations for patients with traumatic brain injury and acute coronary syndrome. PMID- 30281036 TI - Restoring antiviral immunity with adoptive transfer of ex-vivo generated T cells. AB - PURPOSE OF REVIEW: Latent viruses such as cytomegalovirus (CMV), Epstein-Barr virus (EBV) and adenovirus (ADV) often reactivate in immunocompromised patients, contributing to poor clinical outcomes. A rapid reconstitution of antiviral responses via adoptive transfer of virus-specific T cells (VSTs) can prevent or eradicate even refractory infections. Here, we evaluate this strategy and the associated methodological, manufacturing and clinical advances. RECENT FINDINGS: From the early pioneering but cumbersome efforts to isolate CMV-specific T cell clones, new approaches and techniques have been developed to provide quicker, safer and broader-aimed ex-vivo antigen-specific cells. New manufacturing strategies, such as the use of G-Rex flasks or 'priming' with a library of overlapping viral peptides, allow for culturing greater numbers of cells that could be patient-specific or stored in cell banks for off-the-shelf applications. Rapid isolation of T cells using major histocompatibility complex tetramer or cytokine capture approaches, or genetic reprogramming of cells to target viral antigens can accelerate the generation of potent cellular products. SUMMARY: Advances in the ex-vivo generation of VSTs in academic medical centres and as off the-shelf blood bank-based or commercially produced reagents are likely to result in broader accessibility and possible manufacturing cost reduction of these cell products, and will open new therapeutic prospects for vulnerable and critically ill immunocompromised patients. PMID- 30281037 TI - Towards increasing shelf life and haemostatic potency of stored platelet concentrates. AB - PURPOSE OF REVIEW: Platelet transfusion is a widely used therapy in treating or preventing bleeding and haemorrhage in patients with thrombocytopenia or trauma. Compared with the relative ease of platelet transfusion, current practice for the storage of platelets is inefficient, costly and relatively unsafe, with platelets stored at room temperature (RT) for upto 5-7 days. RECENT FINDINGS: During storage, especially at cold temperatures, platelets undergo progressive and deleterious changes, collectively termed the 'platelet storage lesion', which decrease their haemostatic function and posttransfusion survival. Recent progress in understanding platelet activation and host clearance mechanisms is leading to the consideration of both old and novel storage conditions that use refrigeration and/or cryopreservation to overcome various storage lesions and significantly extend platelet shelf-life with a reduced risk of pathogen contamination. SUMMARY: A review of the advantages and disadvantages of alternative methods for platelet storage is presented from both a clinical and biological perspective. It is anticipated that future platelet preservation involving cold, frozen and/or pathogen reduction strategies in a proper platelet additive solution will enable longer term and safer platelet storage. PMID- 30281038 TI - Impact of air pollution on depression and suicide. AB - Air pollution is one of the greatest public health threats worldwide. All substances appearing in excessive quantities in the atmosphere, such as particulate matter, nitrogen oxides or sulphur oxides may be its ingredients. Depending on their size and nature, these compounds may cause greater risk of suffering from respiratory or cardiovascular diseases for exposed people as well as exacerbation and increased mortality due to these illnesses. Smaller particles may penetrate the brain's blood barrier and thus affect the central nervous system. In many studies, they have been shown to have negative effects on brain structure, like diminishing white matter or neuronal degeneration, leading to the earlier onset of Alzheimer or Parkinson disease. Nevertheless, there are reports of association of air pollution with mood disorders, depression, and even suicide. There are many risk factors for these conditions, most important of which are the social situation or chronic diseases. However, it has also been confirmed that the environment may affect mental health. This article will present experimental, clinical and epidemiological studies on exposure to air pollution and its impact on depressive disorders and suicide. Our goal is to determine the relationship between air pollution and incidence of depression and suicides. PMID- 30281040 TI - ? PMID- 30281039 TI - [Evaluation of adverse drug reactions associated with direct oral anticoagulants recorded in the Italian Pharmacovigilance Network database using a specifically developed risk index]. AB - The introduction into clinical practice of direct oral anticoagulants (DOAC) has widened the scenario in the prevention and treatment of thromboembolism. However, the evaluation of the balance between the thrombotic and hemorrhagic risks is a critical issue in the choice of an oral anticoagulant agent. The availability of safety and efficacy data for each drug represents the basis to operate treatment choices. As there are no head-to-head studies comparing the different DOACs in terms of safety and efficacy, and considering the differences in registrative trial designs and characteristics of enrolled populations, several meta-analyses and real-life studies have tried to trace the safety and efficacy profiles on DOACs, but at present no definitive conclusions can be drawn due to numerous existing biases. One possible aid to help clinicians in their treatment choice is the evaluation of self-reported adverse drug reactions (ADRs) available in drug regulatory agency databases such as the Italian Medicines Agency (AIFA) pharmacovigilance database. We conducted a search in the National Pharmacovigilance Network database, available on AIFA website, in order to retrieve all the ADRs related to oral anticoagulants occurred in the period 2016 2017. We then calculated an ADR risk index (RI) for each drug, where an RI =1 indicates a balance between the percentage of ADR share and the percentage of market share for each DOAC; and an RI <1 indicates a rate of ADR lower than the rate of market share (more safe DOAC). The results showed that rivaroxaban is the DOAC with the lowest RI among the four molecules available today in Italy. Despite the limitations of this study, we believe that ADR RI can be a valuable adjunctive tool to help clinicians in their everyday clinical practice. PMID- 30281041 TI - [Which role today for intra-aortic balloon counterpulsation?] AB - Intra-aortic balloon pump (IABP) is a percutaneous assist device that is easy to implant, is associated with low complication rates and, therefore, is widely used. It is commonly applied by femoral access, although it can be used with axillary access. It reduces afterload and preload, with a slight increase in mean arterial pressure and coronary perfusion. For these characteristics, it has been extensively used in cardiogenic shock, even without a clear demonstration of efficacy from randomized clinical trials; the IABP-SHOCK II study, the largest trial carried out so far, failed to demonstrate the usefulness of IABP in this setting. Furthermore, the routine use of IABP in patients with acute anterior myocardial infarction was not associated with any benefit in reducing ischemic area at cardiac magnetic resonance, as shown by the CRISP-AMI trial. For these reasons, the international guidelines do not support the routine use of IABP in acute myocardial infarction complicated by cardiogenic shock, suggesting instead its use in different scenarios such as heart failure associated with acute mechanical complications or acute myocarditis. IABP is currently used in patients undergoing percutaneous coronary interventions or surgical coronary revascularization judged at high risk of complications. In the former scenario, the evidence from the literature is very scarce; in the latter one, small trials and meta-analytical studies suggest a treatment benefit with IABP in the preoperative period.Despite limited evidence of efficacy, IABP will continue to play an important role in today's cardiology and is going to remain the most widely used mechanical circulatory support device. PMID- 30281042 TI - [Prevention of cardioembolic events after intracranial hemorrhage]. AB - In high thromboembolic risk patients who experienced hemorrhagic stroke, the prevention of cardioembolic events and recurrence of intracranial bleeding should be guaranteed. The consultant cardiologist should carefully identify the most appropriate therapeutic approach for these patients. Among patients with previous hemorrhagic stroke, only few restart oral anticoagulant therapy (OAT) after cerebral bleeding; however, as reported by some registries, it is likely that resuming OAT exerts a favorable effect on the combined outcome of ischemic stroke/systemic embolism/all-cause death. In these patients, several parameters should be evaluated, such as the type of intracranial bleeding, the presence of a previous thromboembolic event, the global thromboembolic risk, as well as the history of a previous OAT. This review deals with a particularly interesting matter, requiring a number of decision-making turning points, i.e. whether it is appropriate or not to start or resume OAT, what drug class and timing choice in such a case, and the potential valuable alternatives to OAT. PMID- 30281043 TI - [Antithrombotic therapy in patients with atrial fibrillation and acute coronary syndrome]. AB - Antithrombotic therapy in patients with atrial fibrillation and acute coronary syndrome is a difficult challenge because of the need of taking into consideration three different issues: the cardiac ischemic risk related to coronary artery disease and its treatment with angioplasty and stenting; the thromboembolic risk associated with atrial fibrillation; and the hemorrhagic risk related to the combined use of antiplatelet therapy (with one or two agents) and oral anticoagulant therapy.Data from many trials and meta-analyses currently support a combination therapy with oral anticoagulants (vitamin K antagonists or direct oral anticoagulants) and antiplatelet agents (aspirin and clopidogrel in dual or single antiplatelet therapy).Recently completed and ongoing trials aim to tackle the still controversial issues of this therapy: the choice of the anticoagulant agent and its dosage; the choice of the antiplatelet agent; the use of single or dual antiplatelet therapy and its duration. PMID- 30281044 TI - [Percutaneous closure of a very large atrial septal defect: a case report and literature review]. AB - Percutaneous transcatheter closure of ostium secundum atrial septal defects (ASD) is the gold-standard treatment, because of a comparable efficacy and less complications than heart surgery. Nevertheless, percutaneous treatment of very large ASD is still considered a challenging procedure and is discouraged for diameters larger than 38 mm, especially when atrial septal rims are absent. These patients are characterized by more frequent complications when a percutaneous approach is attempted. Hence, the treatment of choice is still debated. We report the case of a 75-year-old Caucasian male, admitted for congestive heart failure secondary to a very large ASD. After accurate sizing with transesophageal echocardiography and sizing balloon, percutaneous closure with an Amplatzer Septal Occluder was successfully performed, using few simple tricks. PMID- 30281045 TI - [ANMCO position paper on sacubitril/valsartan in the management of patients with heart failure]. AB - Sacubitril/valsartan, the first-in-class angiotensin receptor neprilysin inhibitor (ARNI), is the first medication to demonstrate a mortality benefit in patients with chronic heart failure and reduced ejection fraction (HFrEF) since the early 2000s. Sacubitril/valsartan simultaneously suppresses renin-angiotensin aldosterone system activation through blockade of angiotensin II type 1 receptors and enhances the activity of vasoactive peptides including natriuretic peptides, through inhibition of neprilysin, the enzyme responsible for their degradation. In the landmark PARADIGM-HF trial, patients with HFrEF treated with sacubitril/valsartan had a 20% reduction in the primary composite endpoint of cardiovascular death or heart failure hospitalization, a 20% lower risk of cardiovascular death, a 21% to 20% lower risk of a first heart failure hospitalization, and a 16% to 20% lower risk of death from any cause, compared with subjects allocated to enalapril (all p<0.001).Following the trial, new international guidelines endorsed sacubitril/valsartan as a class I recommendation for the management of patients with HFrEF who remain symptomatic despite optimal medical management. In Italy, sacubitril/valsartan is reimbursed by the National Health Service since March 2017 within criteria set by the Italian Medicines Agency subject to patient inclusion in a dedicated monitoring registry. Although numerous post-hoc analyses of the original trial suggested that the benefits of this innovative medication may extend across a variety of subgroups, many questions do not yet have an evidence-based answer.In this position paper, we discuss the current role of sacubitril/valsartan in the management of chronic HFrEF, treatment eligibility and the modulating role of patients' characteristics. Moreover, we address concerns elicited by the PARADIGM HF study and shortcomings of this novel drug, to clarify the place of this new therapy in the context of global care of heart failure in Italy. Our aim is to provide clinical cardiologists with a concise and practical guidance on when and how to use sacubitril/valsartan, to assist clinicians in closing the gap between scientific innovation and real-world experience. PMID- 30281046 TI - [Appropriateness criteria for the management of anticoagulant therapy in complex patients with atrial fibrillation. The opinion of a group of expert Italian cardiologists]. AB - Atrial fibrillation (AF) is a common arrhythmia often associated with high thromboembolic risk. The purpose of this position paper is to provide clinicians with recommendations useful in managing some important issues regarding the use of anticoagulant therapy in patients with AF in particularly complex clinical situations.The RAND/UCLA appropriateness method, validated to combine the best available scientific evidence with the collective judgment of experts, was used to assess the judgment of an expert panel of cardiologists. To this purpose, the benefit-to-harm ratio of 37 clinical scenarios was rated. Each indication was classified as "appropriate", "uncertain", or "inappropriate" in accordance with the panelists' median score.The present document reports the results of this consensus process, which led to the development of recommendations for clinical practice on how to use anticoagulant therapy in patients with AF in complex clinical settings, including the presence of comorbidities, cardioversion, or ablation. Non-vitamin K oral anticoagulants are a valid alternative to vitamin K antagonists in preventing embolic events in patients with non-valvular AF, particularly in case of clinical complexity. PMID- 30281047 TI - Polymeric hole-transport materials with side-chain redox-active groups for perovskite solar cells with good reproducibility. AB - Two monomers, M:OO and M:ON, and their corresponding polymers, P:OO and P:ON, were prepared from styrene derivatives N,N-diphenyl-4-vinyl-aniline with different substituents (-OCH3 and -N(CH3)2) in the N-phenyl para positions. The polymers were synthesised and fully characterised to study their function as hole transport materials (HTMs) in perovskite solar cells (PSCs). The thermal, optical and electrochemical properties and performance of these monomers and polymers as HTMs in PSCs were compared in terms of their structure. The polymers form more stable amorphous glassy states and showed higher thermal stability than the monomers. The different substituent in the para position influenced the highest occupied molecular orbital (HOMO) level, altering the oxidation potential. Both monomers and polymers were employed as HTMs in perovskite solar cells with a device configuration FTO/bl-TiO2/mp-TiO2/CH3NH3PbI3/HTM/Au resulting in power conversion efficiencies of 7.48% for M:OO, 5.14% for P:OO, 5.28% for P:ON and 3.52% for M:ON. Although showing comparatively low efficiencies, the polymers showed much superior reproducibility in comparison with Spiro-OMeTAD or the monomers, suggesting further optimisation of polymeric HTMs with redox side groups is warranted. PMID- 30281048 TI - Phosphatidylcholine in the groove of endothelial cell protein C receptor (EPCR) regulates EPCR conformation and protein C recognition. AB - Endothelial cell protein C receptor (EPCR), the cellular receptor for protein C (PC), facilitates PC activation through the thrombin/thrombomodulin complex and regulates thrombin generation. Under pathophysiological conditions like sepsis, the interactions between EPCR and PC become impaired. Previous studies have demonstrated that the EPCR contains a phospholipid in the antigen-binding groove that is responsible for the structural stability of the EPCR and for PC recognition. However, an understanding at the atomic level during ligand recognition is not fully developed. Molecular dynamics simulations along with potential of mean force (PMF) calculations were carried out in order to provide molecular insight into the dynamics and free energies of EPCR-PC in the absence/presence of phospholipid, namely lysophosphatidylcholine (lysoPCh) and phosphatidylcholine (PCh) in the antigen-binding groove of the EPCR. Our data reveal that the presence of lipid maintains the optimal conformation of the EPCR for PC binding. PMF data further suggest that the PCh system is the most stable in comparison with the other systems (lysoPCh and no lipid). With regards to the two hydrophobic tails of PCh, one lipid tail regulates EPCR conformation while the other promotes ligand recognition by interacting with the keel residue (Phe 4) of PC. Due to the lack of one hydrophobic tail for the lysoPCh system, the EPCR conformation is retained but the affinity of the EPCR towards the ligand (PC) is reduced. Our studies for the first time explore the possible mode of ligand recognition by the EPCR via the involvement of phosphatidylcholine within its hydrophobic groove. The present work provides insight into PCh-dependent ligand recognition and hence regulation of the protein C/EPCR complex formation.

AB - Stripe rust caused by Puccinia striiformis f. sp. tritici (Pst) is one of the most devastating diseases of wheat (Triticum spp.) worldwide. Indian isolates were characterised based on their phenotypic reaction on differential hosts carrying different Yr genes. Based on virulence/avirulence structure, isolates were characterised into ten different pathotypes viz. 70S0-2, 67S64, 70S4, 66S0, 70S64, 66S64-1, 38S102, 47S102, 46S119, and 78S84. These Indian pathotypes of P. striiformis f. sp. tritici and 38 pathotypes of other rust species (P. graminis tritici and P. triticina) were used in this study to analyze their molecular phylogenetic relationship. The nucleotides of rDNA-ITS, partial beta-tubulin and ketopantoate reductase genes of all the pathotypes were sequenced directly after PCR. Based on sequence data of rDNA-ITS and beta-tubulin, three phylogenetic groups corresponding to three different species of Puccinia were obtained. Asian isolates formed a distinct evolutionary lineage than from those derived from USA. The sequence similarity of Indian pathotypes with other Asian (China and Iran) isolates indicated the same origin of pathotypes. The results will allow rapid identification of Indian P.striiformis f. sp. tritici pathotypes causing stripe rust in wheat, assist in making predictions regarding potential rust pathotypes, and identifying sources of resistance to the disease in advance. PMID- 30281060 TI - Translumbar hemodialysis long-term catheters: an alternative for vascular access failure. AB - INTRODUCTION: Vascular access (VA) in hemodialysis (HD) is essential to end-stage renal disease (ESRD) patients survival. Unfortunately, after some years in HD program, a significant number of patients may develop VA failure for many reasons. In this situation, arterial venous fistula (AVF) confection or catheters placement in traditional vascular sites (jugular, femoral or subclavian) are not feasible. In this scenario, translumbar tunneled dialysis catheter (TLDC) may be a salvage option. OBJECTIVES: To describe placement technic, complications, and patency of 12 TLDC. METHODS: A retrospective study was performed to analyze 12 TLDC placement in an angiography suite using fluoroscopic guidance at the University Hospital of the Rio Grande do Norte Federal University from January 2016 to October 2017. The data collected of the total procedures performed consisted of demographic characteristics, success rates, observed complications, patient survival, and catheter patency. RESULTS: All 12 TLDC were placed with success; there were only 2 significant periprocedure complications (major bleeding and extubation failure); 41.6% of patients presented a catheter-related first infection after 98 +/- 72.1 (6-201) days, but catheter withdrawal was not necessary, mean total access patency was 315.5 (range 65 - 631) catheter-days, and catheter patency at 3, 6 and 12 months was 91 %, 75%, and 45%. CONCLUSION: TLDC is an option for patients with VA failure, improving survival and acting as a bridge for renal transplantation. PMID- 30281061 TI - Successful multiple-exchange peritoneal dialysis in a patient with severe hematological toxicity by methotrexate: case report and literature review. AB - Methotrexate is an effective medication to control several diseases; however, it can be very toxic, being myelosuppression one of its main adverse effects, which increases in severity and frequency in patients with renal failure. We present the case of a 68-year-old man with chronic, end-stage renal disease associated with ANCA vasculitis, under treatment with peritoneal dialysis, who received the medication at a low dose, indicated by disease activity, which presented as a complication with severe pancytopenia with mucositis that improved with support measures and multiple-exchange peritoneal dialysis. We reviewed 20 cases published to date of pancytopenia associated with methotrexate in patients on dialysis and found high morbidity and mortality, which is why its use in this type of patient is not recommended. However, when this complication occurs, a therapeutic option could be the use of multiple-exchange peritoneal dialysis in addition to supportive therapy for drug-related toxicity, although it is recognized that studies are required to show the role of multiple-exchange peritoneal dialysis in the removal of this medication. PMID- 30281062 TI - Pathophysiological aspects of nephropathy caused by non-steroidal anti inflammatory drugs. AB - Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used medications associated with nephrotoxicity, especially when used chronically. Factors such as advanced age and comorbidities, which in themselves already lead to a decrease in glomerular filtration rate, increase the risk of NSAID-related nephrotoxicity. The main mechanism of NSAID action is cyclooxygenase (COX) enzyme inhibition, interfering on arachidonic acid conversion into E2 prostaglandins E2, prostacyclins and thromboxanes. Within the kidneys, prostaglandins act as vasodilators, increasing renal perfusion. This vasodilatation is a counter regulation of mechanisms, such as the renin-angiotensin-aldosterone system works and that of the sympathetic nervous system, culminating with compensation to ensure adequate flow to the organ. NSAIDs inhibit this mechanism and can lead to acute kidney injury (AKI). High doses of NSAIDs have been implicated as causes of AKI, especially in the elderly. The main form of AKI by NSAIDs is hemodynamically mediated. The second form of NSAID-induced AKI is acute interstitial nephritis, which may manifest as nephrotic proteinuria. Long-term NSAID use can lead to chronic kidney disease (CKD). In patients without renal diseases, young and without comorbidities, NSAIDs are not greatly harmful. However, because of its dose-dependent effect, caution should be exercised in chronic use, since it increases the risk of developing nephrotoxicity. PMID- 30281063 TI - Reversible posterior encephalopathy syndrome in a 10-year-old child. AB - INTRODUCTION: The posterior reversible encephalopathy (PRES) syndrome encompasses a set of clinical-radiological findings associated with severe systemic arterial hypertension. This case report proposes to discuss the identification, diagnosis, and management of PRES in the pediatric population. CASE PRESENTATION: Female patient, 10 years old, admitted to the emergency room with complaint of oliguria and generalized edema. At the initial physical exam, the only alteration present was anasarca. The diagnostic investigation revealed nephrotic syndrome, and clinical treatment was started. She evolved on the 8th day of hospitalization with peak hypertension, sudden visual loss, reduced level of consciousness, nystagmus, and focal seizures requiring intubation. She was transferred to the Intensive Care Unit, with neurological improvement, after the established therapy. CT scan revealed a discrete hypodense area in the white matter of the occipital lobe and anteroposterior groove asymmetry, compatible with PRES. DISCUSSION: PRES is due to vasogenic cerebral edema of acute or subacute installation. Symptoms include headache and altered consciousness, stupor, coma, neurological deficits, seizures and cortical blindness. Nephropathies are the main cause of PRES in pediatrics. Magnetic resonance imaging with diffusion of molecules is the gold standard for diagnosis. The initial treatment objectives are the reduction of blood pressure, antiepileptic therapy, correction of hydroelectrolytic and acid-base disorders and management of intracranial hypertension. CONCLUSION: PRES is associated with acute hypertension. Early diagnosis and proper management may determine a better prognosis and minimize the severity of the clinical course. PMID- 30281064 TI - Thumb adductor muscle thickness used in the nutritional assessment of chronic kidney disease patients under conservative treatment. AB - INTRODUCTION: Evaluate the association between the thumb adductor muscle thickness and the patient's nutritional status, and propose cutoff points for muscle mass depletion in elderly patients with chronic kidney disease (CKD) under conservative treatment. Epidemiological and cross-sectional study, including patients with CKD stages 3 to 5, older than 60 years. Socioeconomic, clinical, physical activity and anthropometric data was obtained. TAMT was described and compared according to CKD stage, socioeconomic data, physical activity, nutritional status and correlated with age, glomerular filtration rate and anthropometric variables. Receiver Operating Characteristic (ROC) curves were produced, considering the lean tissue index classification as reference. The cut off point was defined by the Youden index. RESULTS: We evaluated 137 individuals. The TAMT was lower in malnourished and/or depleted muscle mass individuals; among males it was higher among those who practiced physical activities (p <0.05). This measure was moderately correlated with BMI, calf and brachial circumferences, lean body tissue, lean tissue index and body cell mass (r <0.7); negatively with age (r = -0.34). The ROC curve analysis determined cut points of 15.33 mm for females and 20.33 mm for males, with 72.22% and 62.50% accuracy, respectively. CONCLUSION: TAMT is used to estimate muscle mass and we suggest the cutoff point is useful to rule out the likelihood of muscle mass depletion. It is recommended that it be used in a complementary way in nutritional assessment. PMID- 30281065 TI - IgA nephropathy in Salvador, Brazil: a more aggressive disease? PMID- 30281066 TI - A Phase II Randomized, Control Trial of Group B Streptococcus (GBS) Type III Capsular Polysaccharide -Tetanus Toxoid (GBS III-TT) Vaccine to Prevent Vaginal Colonization with GBS III. AB - Background: Group B Streptococcus (GBS) frequently colonizes pregnant women and can cause sepsis and meningitis in young infants. If colonization was prevented through maternal immunization, a reduction in perinatal GBS disease might be possible. A GBS type III capsular polysaccharide (CPS)-tetanus toxoid conjugate (III-TT) vaccine was evaluated for safety and efficacy in preventing acquisition of GBS colonization. Methods: Healthy, age 18-40 years, non-pregnant women, screened to be GBS III vaginal and rectal culture negative, were randomized to receive III-TT conjugate or tetanus diphtheria toxoid (Td) vaccine in a multicenter, observer blinded trial. GBS vaginal and rectal cultures and blood were obtained bimonthly over 18 months. Serum concentrations of GBS III CPS specific antibodies were determined by ELISA. Results: Among 1525 women screened 650 were eligible for the intent to treat analysis. For time to first acquisition of vaginal GBS III, vaccine efficacy was 36% (95% CI 1-58%, P = .044) and for first rectal acquisition it was this was 43% (95% CI 11-63%, P =.014). Geometric mean concentrations of serum GBS type III CPS-specific IgG, 2 months post immunization were 12.6 ug/ml (95% CI 9.95-15.81) in GBS III-TT recipients representing a 4-fold increase from baseline in 95% of women which persisted. Both vaccines were well tolerated. Conclusion: GBS CPS III-TT conjugate vaccine significantly delayed acquisition of vaginal and rectal GBS III colonization. Besides its use for maternal immunization to passively protect infants with maternally-derived antibodies, a multivalent vaccine might also serve to reduce fetal and neonatal exposure to GBS.

PMID- 30281068 TI - Malocclusion Can Give Additional Hints for Diagnosis of Fetal Alcohol Spectrum Disorder. AB - Aims: Fetal alcohol spectrum disorder (FASD) is a developmental disorder caused by maternal alcohol intake (prevalence: 0.77%). Malocclusion has been described in case reports of patients with FASD, but reliable evidence for associations between FASD and malocclusion is not documented. Malocclusion is defined as tooth irregularity (prevalence: 14.6%) or incorrect relationship between the jaws such as lateral crossbites (prevalence: 3.1%). The purpose of this study was to investigate possible associations between malocclusion and FASD. Short summary: FASD prevalence is high and diagnosis is very difficult; Malocclusions can give additional hints for FASD diagnosis; Patients with FASD show growth deficits concerning the maxilla; Early and consistent orthodontic supervision and therapy can prevent facial asymmetries in FASD patients. Methods: Thirty patients with FASD and 30 patients of a healthy control group were examined. Inclusion criteria were mixed dentition, verified FASD/absence of FASD (control group), exclusion criteria were orthodontic treatment and disorders other than FASD. The extent and type of malocclusion were quantified with the peer assessment rating (PAR) index based on an analysis of orthodontic plaster models. In addition, anthropometric data such as gestational age, body weight and height at birth as well as present body weight, height and head circumference at examination date were assessed. Results: The PAR index showed a significant increase in malocclusions in FASD patients compared to the group that were not diagnosed with FASD (P = 0.002). FASD patients showed particular differences in the upper transversal dimension with a higher prevalence of crossbites (P = 0.018) and a lower head circumference (P < 0.001). Body weight (P < 0.001) and height (P < 0.001) were significantly lower for FASD patients at time of birth, but not at the present examination date (weight: P = 0.329; height: P = 0.496). When relating weight and height measures to age using percentile curves of physiological growth, clinically relevant discrepancies could be found for FASD patients. Conclusions: Our results show that malocclusion can provide additional evidence for FASD diagnosis. When FASD is diagnosed in a child, early referral to an orthodontist is advisable to stimulate maxillary growth and consequently prevent further malocclusions. PMID- 30281069 TI - Invasive pneumococcal disease in UK children under 1 year of age in the post PCV13 era: what are the risks now? AB - Background: Invasive pneumococcal disease (IPD) has declined significantly since the introduction of pneumococcal conjugate vaccines (PCV). It is not known whether certain infant populations remain at higher risk of IPD in countries with established PCV13 programmes. We aimed to describe the epidemiology, clinical characteristics, serotype distribution and outcomes of IPD in infants, and to estimate the relative risk of PCV13-type, non-PCV13 type and overall IPD in premature infants compared to term infants during a four-year period after the PCV13 programme was established. Methods: Prospective, enhanced national surveillance of laboratory-confirmed IPD in England in infants aged <1 year diagnosed during 2013-16. Results: There were 517 cases of IPD (incidence: 19/100,000 infants). Incidence was significantly higher in premature infants compared with those born at term (49/100,000 vs 17/100,000; incidence rate ratio (IRR) 2.87; p<0.001) with infants born below 28 weeks gestation having the highest incidence (150/100,000; IRR 8.8; p<0.001). Of the 454 IPD cases with serotyped isolates, most were caused by non-PCV13 serotypes (369 cases, 71.4%), with 85 cases (16.4%) due to PCV13 serotypes. There were 31 deaths (case fatality rate 6.2%; 95% CI, 4.3-8.6%). Premature infants did not have a higher CFR than term infants (p=0.62). Conclusion & relevance: IPD incidence in infants remains lower than rates reported prior to PCV7 introduction in England. The risk of IPD remains significantly higher in premature infants compared to infants born at term, for both PCV13 and non-PCV13 serotypes. Any changes to the infant PCV13 immunisation schedule may disproportionally affect premature infants. PMID- 30281070 TI - Infants at risk for Invasive Pneumococcal Disease in the PCV13 Era. PMID- 30281071 TI - New avenues for antimicrobial stewardship: the case for penicillin skin testing by pharmacists. AB - It is well-appreciated that patients with documented penicillin allergies often receive broader-spectrum antibiotics. This practice has been associated with increased antimicrobial resistance and cost. In recent years, considerable efforts have been made to spread awareness on the implications of self-reported penicillin allergies. The use of penicillin skin testing to evaluate for true allergies has been strongly recommended by major organizations for decades. However, testing remains underutilized. Current literature has suggested various models incorporating penicillin allergy screening and testing by different health care practitioners (i.e., physicians, allergists, nurses, pharmacists). We suggest broader adoption for the role of pharmacists in provision of penicillin skin testing. This would help expand the service and maximize the potential benefits of penicillin skin testing. PMID- 30281073 TI - Randomised study demonstrates sustained benefits of a pre-school intervention designed to improve nutrition and physical activity practices. AB - Background: Health-promoting programmes must demonstrate sustained efficacy in order to make a true impact on public health. This study aimed to determine the effect of the Healthy Incentive for Pre-schools project on health-promoting practices in full-day-care pre-schools 18 months after a training intervention. Methods: Thirty-seven pre-schools completed the initial study and were included in this follow-up study. The intervention consisted of one training session with either the pre-school 'manager-only' or 'manager and staff' using a specifically developed needs-based training resource pack comprised of written educational material and a validated health-promoting practice evaluation tool. Direct observation data of health-promoting practices were collected and allocated a score using the evaluation tool by a research dietitian at three time points; pre intervention, between 6 and 9 months post-intervention and at 18-month follow-up. An award system was used to incentivise pre-schools to improve their scores. Results: Health-promoting practice scores improved significantly (P < 0.001) from the 6-9 month post-intervention to the 18-month follow-up evaluation. No significant differences were observed between 'manager-only' and 'manager and staff' trained pre-schools. Conclusions: The introduction of a pre-school evaluation tool supported by a training resource was successfully used to incentivise pre-schools to sustain and improve health-promoting practices 18 months after intervention training. PMID- 30281072 TI - Preoperative oral antibiotic prophylaxis reduces surgical site infections after elective colorectal surgery: results from a before-after study. AB - Background: Surgical site infections (SSI) are common complications after colorectal procedures and remain an important source of morbidity and costs. Preoperative oral antibiotic prophylaxis is a potential infection control strategy, but its effectiveness without simultaneous use of mechanical bowel preparation (MBP) is unclear. In this study, we aimed to determine whether preoperative oral antibiotics reduce the risk of deep SSI in elective colorectal surgery. Methods: We performed a before-after analysis in a teaching hospital in the Netherlands. Patients who underwent surgery between January 2012 and December 2015 were included. On January 1 st, 2013, oral antibiotic prophylaxis with tobramycin and colistin was implemented as standard of care prior to colorectal surgery. The year before implementation was used as control period. The primary outcome was a composite of deep surgical site infection and/or mortality within 30 days after surgery. Results: Of the 1,410 patients, 352 underwent colorectal surgery in the control period and 1,058 in the period after implementation of the antibiotic prophylaxis. We observed a decrease in incidence of the primary endpoint of 6.2% after prophylaxis implementation. When adjusted for confounders, the risk ratio for development of the primary outcome was 0.58 (95% CI 0.40 - 0.79). Other findings included a decreased risk of anastomotic leakage and a reduction of the length of postoperative stay. Conclusions: reoperative oral antibiotic prophylaxis prior to colorectal surgery is associated with a significant decrease in SSI and/or mortality in a setting without MBP. Preoperative oral antibiotics can therefore be considered without MBP for patients undergoing colorectal surgery. PMID- 30281074 TI - Locking hemodialysis catheters with Trimethoprim-Ethanol-Ca-EDTA to prevent bloodstream infections. A randomized, evaluator blinded clinical trial. AB - Background: Central line associated bloodstream infections(CLABSI) often result from intraluminal microbial colonization and are associated with morbidity, mortality, and substantial costs. The use of antimicrobial catheter lock solutions may reduce the incidence of CLABSI. Methods: Patients undergoing hemodialysis through a prevalent central venous catheter(CVC) were randomly assigned to have their CVC locked between dialysis sessions with an antimicrobial catheter lock solution containing trimethoprim 5 mg/mL, Ethanol 25% and Ca-EDTA 3%(Investigational Medical Device, IMD) or heparin 5,000 U/mL(Active Control Heparin, ACH). Exit site care was standardized by protocol-driven use of skin antiseptics and occlusive dressings. The composite primary endpoint consisted of the incidence of CLABSI and the use of intra-catheter thrombolytic treatment(TT). Given the viscosity and odor of the IMD, blinding was impossible. Therefore, the incidence of CLABSI was adjudicated by a blinded endpoint committee. Results: 270 patients on hemodialysis were enrolled and followed for a total of 43,738 CVC days. Despite the low CLABSI incidence of 0.41/1,000 CVC days in patients randomized to ACH, the IMD further reduced the incidence 4.56-fold to 0.09/1,000 CVC days(P<0.03). The product was well tolerated, and the frequency and severity of adverse events were comparable between groups. Intracatheter instillation of thrombolytics was more frequent in patients receiving the IMD (12% ACH, 40% IMD;P<0.001) but rates of catheter removal did not differ(13% in ACH and 11% in IMD). Overall dialysis adequacy was comparable between groups. Conclusions: In patients on chronic hemodialysis, a trimethoprim, ethanol and Ca-EDTA Lock solution significantly reduced the incidence of CLABSI. PMID- 30281075 TI - Does military veteran status and deployment history impact officer involved shootings? A case-control study. AB - Background: Despite veterans' preference hiring policies by law enforcement agencies, no studies have examined the nature or effects of military service or deployments on health outcomes. This study will examine the effect of military veteran status and deployment history on law enforcement officer (LEO)-involved shootings. Methods: Ten years of data were extracted from Dallas Police Department records. LEOs who were involved in a shooting in the past 10 years were frequency matched on sex to LEOs never involved in a shooting. Military discharge records were examined to quantify veteran status and deployment(s). Multivariable logistic regression was used to estimate the effect of veteran status and deployment history on officer-involved shooting involvement. Results: Records were abstracted for 516 officers. In the adjusted models, veteran LEOs who were not deployed were significantly more likely to be involved in a shooting than non-veteran officers. Veterans with a deployment history were 2.9 times more likely to be in a shooting than non-veteran officers. Conclusions: Military veteran status, regardless of deployment history, is associated with increased odds of shootings among LEOs. Future studies should identify mechanisms that explain this relationship, and whether officers who experienced firsthand combat exposure experience greater odds of shooting involvement.

PMID- 30281077 TI - Failure after two-stage exchange arthroplasty for treatment of periprosthetic joint infection: the role of antibiotics in the cement spacer. AB - Introduction: Failure after a two-stage exchange surgery for periprosthetic joint infections (PJI) is high. Previous studies demonstrated that positive cultures at reimplantation are associated with failure afterwards. The aim of this multicenter study was to define the role of antibiotics in the cement spacer in relation to reimplantation cultures and subsequent failure. Methods: We retrospectively evaluated two-stage exchange procedures between 2000 and 2015. Culture-negative PJIs, cases in whom no cultures were obtained during reimplantation and cases without data on cement spacers were excluded. Results: 344 cases were included. The rate of positive cultures during reimplantation was 9.5% for cement spacers containing a glycopeptide (27/284) (with or without an aminoglycoside) versus 21.7% for those containing monotherapy with an aminoglycoside (13/60) (p 0.008), and was mostly attributed by a reduction in coagulase-negative staphylococci (CoNS) (17% versus 2%, p < 0.001). Failure rate was more than two-folds higher at 40.0% (16/40) in cases with positive cultures at reimplantation compared to 15.8% (48/304) for those with negative cultures (p < 0.001). Overall, a glycopeptide in the cement spacer was not associated with a lower failure rate (18% versus 23%, p 0.3), but was associated with lower failure due to CoNS (2.5% versus 13.3%, p < 0.001). Conclusion: In a two-stage exchange procedure for PJI, adding a glycopeptide to the cement spacer reduces the rate of positive cultures during reimplantation and is associated with a lower failure rate due to CoNS afterwards. PMID- 30281078 TI - Epidemiological scenario of anisakidosis in Spain based on associated hospitalizations: the tipping point of the iceberg. AB - Background: The risk of infection with Anisakis has been recognized for some time, but it is now emerging due to major awareness, better diagnostic techniques and increasing preference for raw or lightly cooked food. Spain has the second highest reported incidence after Japan, though the real anisakidosis burden is unknown because of the scarcity of epidemiological data. This study provides a 19 years review of the anisakidosis related hospitalizations describing epidemiological trends and patients' characteristics. Methods: We performed a retrospective descriptive study using the Spanish Hospitalization Minimum Data Set (CMBD) from 1997 to 2015. Hospitalization rates were calculated and spatial distribution of cases and their temporal behavior were assessed. Clinical characteristics were described, including related co-diagnoses and procedures. Results and conclusions: A total of 2,471 hospital discharges were identified. A continuous increasing trend was observed, with several peaks. Most affected communities were located in the north-west inland part of the country. Almost 54% of hospitalized patients were male, mean age of 51.3 years. Median length of stay was 5 days, and the hospitalization median cost around 2,900 euros. Fatal outcome occurred in 0.5%. Most frequent co-diagnoses were digestive diseases, mainly intestinal obstruction. Urticaria, anaphylactic reaction and angioneurotic edema were only recorded in 2.2%, 2.4% and 1.2%, respectively. Knowing that hospitalization is unusual in anisakidosis, we offer calculations of the real disease burden. Improving disease surveillance in parallel to disease control will result useful both in gaining extended disease knowledge and reducing morbidity and related-costs. PMID- 30281079 TI - Long duration of asymptomatic Mycoplasma genitalium infection after syndromic treatment for nongonococcal urethritis. AB - Background: Although Mycoplasma genitalium (MG) is an acknowledged cause of nongonococcal urethritis (NGU), access to diagnostic testing is limited. Syndromic management is common, yet little is known about natural history. Methods: Between August 8, 2014-April 15, 2016 a case series of 13 heterosexual men >=16 years with MG was identified within a cohort study of men with and without NGU attending an urban Sexually Transmitted Diseases Clinic. Men had monthly visits for 6-7 months. NGU was defined as >=5 polymorphonuclear leukocytes per high power field on urethral Gram stain plus either visible urethral discharge or urethral symptoms. Men with NGU received one gram azithromycin. Men with persistent NGU received moxifloxacin 400mg x 14 days. First-void urine was retrospectively tested for MG using TMA. Resistance associated mutations were detected by PCR and sequencing. Organism load was determined by quantitative PCR. Results: Sixty-two percent of MG-positive men had a macrolide resistance mediating mutation (MRMM) at enrollment; 31% had parC mutations (all outside the quinolone resistance determining region). MG persisted after azithromycin in seven men, six of whom had MRMM. The median duration of persistence in the absence of curative therapy was 143 days (range 21-228). Five men experienced symptom resolution after azithromycin but MG persisted for another 89-186 days before moxifloxacin. Organism load was somewhat lower in MRMM than wild type infections (p=0.16). Conclusions: The high prevalence of macrolide resistance and long duration of persistent MG infection after symptom resolution highlights the need for diagnostic testing of men with NGU to direct therapy. PMID- 30281080 TI - Recent progress in organoid culture to model intestinal epithelial barrier functions. AB - The intestinal epithelium not only acts as the physical structure that separates the intestinal lumen from the body but also actively participates in intestinal barrier functions. In the past decade, significant progress has been made in the development of culture technologies to maintain intestinal epithelial cells (IECs) as various forms of intestinal organoids. As these organoids allow for restoration of the physiological composition of IECs, they represent suitable models to study the mechanisms of development and differentiation or the molecular basis of functions in specific types of IECs, such as goblet cells, Paneth cells, tuft cells and M cells. In addition, intestinal organoids are now widely used as model systems to investigate the dynamic processes occurring at the host-microbe interface and the mutual interactions between IECs and the cells involved in the maintenance of local immune homeostasis. In this review article, I showcase recent work that has utilized intestinal organoids to study various aspects of intestinal epithelial barrier functions.

PMID- 30281082 TI - Clostridium difficile in Immunocompromised Hosts: A Review of Epidemiology, Risk Factors, Treatment, and Prevention. AB - Clostridium difficile is a significant pathogen in healthcare today, impacting both hospitalized and community-based patients. Immunocompromised patients experience a high incidence of C. difficile infection, ranging from 6% to 33% in the hematology-oncology population, up to 23% among lung transplant recipients, and a rate of 7.1-8.3 cases per 1000 patient years in patients with human immunodeficiency virus. Recurrence of C. difficile infections among immunocompromised patients is also high, with rates up to 40% in both the hematology-oncology population and solid organ transplant recipients. This higher incidence of C. difficile infection and recurrence is believed to be secondary to frequent antimicrobial use, suppressed immune function, increased exposure to healthcare settings, and higher prevalence of C. difficile colonization. This review summarizes published data describing the epidemiology, risk factors for acquisition and infection, treatment, and prevention of C. difficile in hematology-oncology, solid organ transplant, and human immunodeficiency virus infected patients. PMID- 30281083 TI - Drug-free holidays: Compliance, tolerability, and acceptability of a 3-day atovaquone/proguanil schedule for pre-travel malaria chemoprophylaxis in Australian travellers. AB - Background: Poor compliance with chemoprophylaxis is a major contributing factor to the risk of malaria in travellers. Pre-travel chemoprophylaxis may improve compliance by enabling 'drug-free holidays'. The standard treatment dose of atovaquone/proguanil (250mg/100mg, 4 tablets/day for 3 days) provides protection against malaria for at least 4 weeks, and could therefore potentially be used for pre-travel chemoprophylaxis. In this study, we assessed the compliance, tolerability, and acceptability of the 3-day atovaquone/proguanil schedule for malarial chemoprophylaxis. Methods: 233 participants were recruited from four specialised travel medicine clinics in Australia. Adults travelling to malaria endemic areas with low/medium risk for <=4 weeks were enrolled, and prescribed the 3-day schedule of atovaquone/proguanil, completed at least one day before departure. Questionnaires were used to collect data on demographics, travel destination, medication compliance, side effects, and reasons for choosing the 3 day schedule. The study was registered with the Australian and New Zealand Clinical Trials Registry, number ACTRN12616000640404. Results: Overall, 97.7% of participants complied with the 3-day schedule. Although side effects were reported in 43.3% of the participants, these were well tolerated, and mainly occurred during the first and second day. None of the participants developed malaria. The main reasons for choosing the 3-day schedule over standard chemoprophylaxis options were that it was easier to remember (72.1%), required taking fewer tablets (54.0%), and to help scientific research (54.0%). Conclusions: The 3-day atovaquone/proguanil schedule had an impressively high compliance rate, and was well tolerated and accepted by travellers. Further studies are required to assess the effectiveness of this schedule for chemoprophylaxis in travellers. PMID- 30281084 TI - Deployment and Disaster Medicine in an Undergraduate Teaching Module. AB - Introduction: Modern health systems have to respond to a wide variety of catastrophic scenarios, from natural disasters to terror attacks. It is reasonable to already start educational approaches for physicians in this field at medical school level. An approach combining civilian disaster medicine and military deployment medicine can be beneficial both for clinical strategies and in undergraduate teaching. Materials and Methods: A curricular 4-week teaching module on "deployment and disaster medicine," interdisciplinarily combining over 12 medical specialties, was launched in the summer semester of 2016 at a civilian medical school. The course was integrated into the undergraduate curriculum by learning spirals. Teaching formats encompassed a total of 72 hours of seminars, clinical case discussions, group work, e-Learning, and practical training. The students' gain in knowledge was analyzed with pre/post-multiple-choice tests and their attitude towards the offer was evaluated. Results: A total of 51 students participated in the module over three semesters. The evaluation revealed that the students were highly satisfied with the offer and felt motivated to increase their engagement with the topic. The students additionally valued the course as a good means of deepening the core curriculum. The pre/post-tests showed a significant gain in knowledge among the students (p < 0.001). Conclusions: The course presented received an overall highly positive feedback from the participating students. The experience of this approach suggests that the combination of civilian and military knowledge and expertise in deployment and disaster medicine may lead to the creation of effective interdisciplinary course concepts. PMID- 30281085 TI - Insecticidal Activity of Local Plants Essential Oils Against Laboratory and Field Strains of Anopheles gambiae s. l. (Diptera: Culicidae) From Burkina Faso. AB - The emergence and intensification of resistance to insecticides in malaria vector populations is the main obstacle to insecticide-based control efforts. The main objective of this study was to evaluate the larvicidal and adulticidal properties of the essential oils (EOs) of Ocimum canum, Hyptis suaveolens, Hyptis spicigera, and Lantana camara on field-collected, pyrethroids-resistant mosquitoes, local laboratory strains, and susceptible 'Kisumu' strain of Anopheles gambiae (Meigen) (Diptera: Culicidae) populations. Larvae and adults of these mosquitoes were challenged against four EOs. The mortality rates of larvae and adults were assessed 24 h after exposure to the EOs. Species identifications and detection of the L1014F and L1014S kdr mutations and the 1575Y super-kdr mutation were carried out using polymerase chain reaction on the pyrethroid-resistant mosquitoes from the field. EO compositions were analyzed by gas chromatography and mass spectrometry. Monoterpene hydrocarbons were the major components of H. suaveolens and H. spicigera EOs (49.8%) and (69.6%), respectively, whereas oxygenated monoterpenes (68.7%) were predominant in the O. canum EO. For L. camara, the component yields were variable, but it was the most effective EO against all strains. The LC50 values for the larvae were 7.73 and 25.63 ppm for the susceptible 'Kisumu' and resistant field strains, respectively. The LC50 for adults was 0.24% for the susceptible strain and 1.98% for the resistant strain. Molecular analysis confirmed the presence of L1014F and N1575Y mutations in resistant Anopheles arabiensis and Anopheles coluzzii mosquitoes from the field. Our results highlighted the potential of the EOs of local plants as insecticides against resistant and susceptible strains of An. gambiae populations. PMID- 30281086 TI - Single-Session Mobile-Augmented Intervention in Serious Mental Illness: A Three Arm Randomized Controlled Trial. AB - Psychosocial interventions for serious mental illness are resource intensive and poorly accessible. Brief interventions (eg, single session) that are augmented by follow-on automated mobile health intervention may expand treatment access. This was a randomized single-blind controlled trial with 255 individuals diagnosed with schizophrenia or bipolar disorder. Participants were randomized to one of three conditions: CBT2go, which combined one individual session of cognitive behavioral therapy with automated thought challenging/adaptive behavior delivered through mobile devices; Self-Monitoring (SM), which combined single-session illness psychoeducation with self-monitoring of symptoms; and treatment-as-usual (TAU). Participants were assessed at baseline, 6 weeks (midpoint), 12 weeks (posttreatment), and 24 weeks (follow-up) with our primary outcome global psychopathology (Brief Psychiatric Rating Scale-expanded version [BPRS-24]), and secondary outcomes community functioning (Specific Level of Function; SLOF) and defeatist performance beliefs (DPBs). We also collected data on adverse events. Outcome analyses on the primary outcome, BPRS Total score, indicated a significant time (0-24 wk) by group interaction with significant but modest improvement comparing two active conditions (CBT2go and SM) relative to TAU. Effects of CBT2go were not different from SM. There was a significant time * group interaction with better SLOF scores in CBT2go across 24 weeks, but not in SM. There were no time-by-group effects on DPBs. DPBs decreased in the CBT2go condition but not in SM. These results indicated that single intervention augmented by mobile intervention was feasible and associated with small yet sustained effects on global psychopathology and, when inclusive of CBT, community function compared with usual care. PMID- 30281087 TI - New applications of sonoelastography in rheumatology: where are we now? AB - Ultrasound elastography (UE) is a non-invasive imaging method that allows the assessment of tissue elastic property. Different UE techniques are currently available (i.e. strain UE and acoustic radiation force impulse UE), with several potential clinical applications. Recent studies investigated the role of UE in two systemic rheumatic diseases and psoriasis. This research added interesting information to the already known applications of UE in the assessment of tendinopathies. In SS, acoustic radiation force impulse UE has shown a potential role in the diagnosis of the disease, with lower sensitivity than and similar specificity to salivary gland histology. In SSc, a potential use of UE in screening pre-clinical disease has been reported. In psoriasis, the use of strain UE in evaluating treatment response has been highlighted. UE is a promising tool in rheumatology, with a potential role in the evaluation of various tissues and pathologies. PMID- 30281088 TI - Metacognition, Personal Distress, and Performance-Based Empathy in Schizophrenia. AB - Background: People with schizophrenia experience significant deficits in the kinds of empathic skills that are the foundation for interpersonal relationships. Researchers have speculated that deficits in empathic skills in schizophrenia may be related to disturbances in metacognition and heightened levels of personal distress. To explore this issue, this study examined whether better metacognition and reduced personal distress would be associated with improved performance on cognitive and affective empathy tasks. Further, we tested whether metacognition moderated the relationship between personal distress and empathy. Method: Fifty eight participants with schizophrenia-spectrum disorders receiving community based treatment completed a self-report questionnaire of personal distress, a performance-based measure of empathy, and an observer-rated interview to assess metacognitive capacity. Results: Correlation analyses revealed that metacognitive capacity, but not personal distress, was significantly associated with cognitive and affective empathy performance. Moderation results suggest the relationship between personal distress and affective empathy performance was significant for those with low metacognition, but that the relationship was the opposite of hypotheses-increased personal distress predicted better performance. This relationship changed at higher levels of metacognition, when increased personal distress became associated with reduced performance. Conclusions: This study is the first of its kind to examine performance-based empathy with metacognition and personal distress. Results suggest interventions targeted to improve metacognition may be useful in enhancing empathic skills. PMID- 30281089 TI - Mortality and causes of death across the systemic connective tissue diseases and the primary systemic vasculitides. AB - Objectives: Studies assessing relative mortality risks across the spectrum of systemic inflammatory rheumatic diseases are largely missing. In this study, we wanted to estimate standard mortality ratios (SMRs) and causes of death in an ethnically homogeneous cohort covering all major CTDs and primary systemic vasculitides (PSVs). Methods: We prospectively followed all incident CTD and PSV cases included in the Norwegian CTD and vasculitis registry (NOSVAR) between 1999 and 2015. Fifteen controls for each patient matched for sex and age were randomly drawn from the Norwegian National Population Registry. Causes of death were obtained from the National Cause of Death Register, death certificates and hospital charts. Results: The cohort included 2140 patients (1534 with CTD, 606 with PSV). During a mean follow-up time of 9 years, 279 of the patients (13%) died, compared with 2864 of 32 086 (9%) controls (P < 0.001). Ten years after diagnosis, the lowest survival was 60% in dcSSc, 73% in anti-synthetase syndrome (ASS) and 75% in lcSSc. In the CTD group, the highest SMRs were observed in dcSSc (SMR 5.8) and ASS (SMR 4.1). In the PSV group, Takayasu arteritis (SMR 2.5) and ANCA-associated vasculitis (SMR 1.5) had the highest SMRs. Major causes of death were cardiovascular disease (CTD 27%, PSV 28%), neoplasms (CTD 25%, PSV 27%), chronic respiratory disease (CTD 20%, PSV10%) and infections (CTD 9%, PSV 16%). Conclusion: We observed premature deaths across the spectrum of CTDs and PSVs, with highest SMRs in dcSSc and ASS. The overall mortality was highest in the CTD group. PMID- 30281090 TI - Polygenic Risk Score for Schizophrenia and Face-Processing Network in Young Adulthood. AB - Development of schizophrenia relates to both genetic and environmental factors. Functional deficits in many cognitive domains, including the ability to communicate in social interactions and impaired recognition of facial expressions, are common for patients with schizophrenia and might also be present in individuals at risk of developing schizophrenia. Here we explore whether an individual's polygenic risk score (PRS) for schizophrenia is associated with the degree of interregional similarities in blood oxygen level-dependent (BOLD) signal and gray matter volume of the face-processing network and whether the exposure to early adversity moderates this association. A total of 90 individuals (mean age 22 years, both functional and structural data available) were used for discovery analyses, and 211 individuals (mean age 26 years, structural data available) were used for replication of the structural findings. Both samples were drawn from the Northern Finland Birth Cohort 1986. We found that the degree of interregional similarities in BOLD signal and gray matter volume vary as a function of PRS; lowest interregional correlation (both measures) was observed in individuals with high PRS. We also replicated the gray matter volume finding. We did not find evidence for an interaction between early adversity and PRS on the interregional correlation of BOLD signal and gray matter volume. We speculate that the observed group differences in PRS-related correlations in both modalities may result from differences in the concurrent functional engagement of the face-processing regions over time, eg, via differences in exposure to social interaction with other people. PMID- 30281091 TI - Cis D4Z4 repeat duplications associated with facioscapulohumeral muscular dystrophy type 2. AB - Facioscapulohumeral muscular dystrophy, known in genetic forms FSHD1 and FSHD2, is associated with D4Z4 repeat array chromatin relaxation and somatic derepression of DUX4 located in D4Z4. A complete copy of DUX4 is present on 4qA chromosomes, but not on the D4Z4-like repeats of chromosomes 4qB or 10. Normally, the D4Z4 repeat varies between 8 and 100 units, while in FSHD1 it is only 1-10 units. In the rare genetic form FSHD2, a combination of a 4qA allele with a D4Z4 repeat size of 8-20 units and heterozygous pathogenic variants in the chromatin modifier SMCHD1 causes DUX4 derepression and disease. In this study, we identified 11/79 (14%) FSHD2 patients with unusually large 4qA alleles of 21-70 D4Z4 units. By a combination of Southern blotting and molecular combing, we show that 8/11 (73%) of these unusually large 4qA alleles represent duplication alleles in which the long D4Z4 repeat arrays are followed by a small FSHD-sized D4Z4 repeat array duplication. We also show that these duplication alleles are associated with DUX4 expression. This duplication allele frequency is significantly higher than in controls (2.9%), FSHD1 patients (1.4%) and in FSHD2 patients with typical 4qA alleles of 8-20 D4Z4 units (1.5%). Segregation analysis shows that, similar to typical 8-20 units FSHD2 alleles, duplication alleles only cause FSHD in combination with a pathogenic variant in SMCHD1. We conclude that cis duplications of D4Z4 repeats explain DUX4 expression and disease presentation in FSHD2 families with unusual long D4Z4 repeats on 4qA chromosomes. PMID- 30281092 TI - Cmah-dystrophin deficient mdx mice display an accelerated cardiac phenotype that is improved following peptide-PMO exon skipping treatment. AB - Duchenne muscular dystrophy (DMD) is caused by loss of dystrophin protein, leading to progressive muscle weakness and premature death due to respiratory and/or cardiac complications. Cardiac involvement is characterized by progressive dilated cardiomyopathy, decreased fractional shortening and metabolic dysfunction involving reduced metabolism of fatty acids-the major cardiac metabolic substrate. Several mouse models have been developed to study molecular and pathological consequences of dystrophin deficiency, but do not recapitulate all aspects of human disease pathology and exhibit a mild cardiac phenotype. Here we demonstrate that Cmah (cytidine monophosphate-sialic acid hydroxylase)-deficient mdx mice (Cmah-/-;mdx) have an accelerated cardiac phenotype compared to the established mdx model. Cmah-/-;mdx mice display earlier functional deterioration, specifically a reduction in right ventricle (RV) ejection fraction and stroke volume (SV) at 12 weeks of age and decreased left ventricle diastolic volume with subsequent reduced SV compared to mdx mice by 24 weeks. They further show earlier elevation of cardiac damage markers for fibrosis (Ctgf), oxidative damage (Nox4) and haemodynamic load (Nppa). Cardiac metabolic substrate requirement was assessed using hyperpolarized magnetic resonance spectroscopy indicating increased in vivo glycolytic flux in Cmah-/-;mdx mice. Early upregulation of mitochondrial genes (Ucp3 and Cpt1) and downregulation of key glycolytic genes (Pdk1, Pdk4, Ppara), also denote disturbed cardiac metabolism and shift towards glucose utilization in Cmah-/-;mdx mice. Moreover, we show long-term treatment with peptide-conjugated exon skipping antisense oligonucleotides (20-week regimen), resulted in 20% cardiac dystrophin protein restoration and significantly improved RV cardiac function. Therefore, Cmah-/-;mdx mice represent an appropriate model for evaluating cardiac benefit of novel DMD therapeutics. PMID- 30281093 TI - Outcome of Pregnancies in Female Patients With Inflammatory Bowel Diseases Treated With Vedolizumab. AB - Background and Aims: Vedolizumab is an IgG1 anti-alpha4beta7 integrin antibody approved for the treatment of inflammatory bowel diseases [IBD], but without clear safety data during conception, pregnancy and nursing. Animal studies showed that mucosal vascular addressin cell adhesion molecule 1 [MAdCAM-1] is expressed by maternal vessels in the placenta and recruits alpha4beta7-expressing cells that are considered important for maternal/fetal tolerance. Blocking this interaction by vedolizumab might affect this process. We aimed to evaluate pregnancy outcomes in vedolizumab-treated female IBD patients. Methods: We conducted a retrospective, multicentre Belgian observational study. Details on disease activity, prenatal complications, delivery and neonatal outcome were collected through a case report form. Results: Twenty-four pregnancies were reported. Five women had active disease at conception and one patient flared during pregnancy. There were 23 live births. Complications were observed in 25% of pregnancies [premature rupture of membranes, pre-eclampsia, miscarriage, elective termination and stillbirth] and in 35% of infants [prematurity, intra uterine growth retardation, small for gestational age and congenital malformations including hip dysplasia, pulmonary valve stenosis and Hirschprung's disease]. Vedolizumab was continued throughout pregnancy in two females and stopped in the 1st and 2nd trimester in five and 16 patients, respectively. For live born children, the median [interquartile range] gestational age, weight and Apgar score 5 min after birth were 39 [37-39.6] weeks, 3270 [3080-3585] grams and 10 [9-10], respectively. Conclusions: Although several complications were observed, both in mothers and in newborns, no firm conclusions can be drawn. Awaiting prospective and controlled registries, vigilance and strict follow-up of pregnant patients treated with vedolizumab seems mandatory. PMID- 30281094 TI - Hit Improves Aerobic Capacity Without a Detrimental Decline in Blood Glucose in People with Type 1 Diabetes. AB - AIMS: To investigate whether 1) six weeks of high-intensity interval training (HIT) induces similar improvements in cardio-metabolic health markers as moderate intensity continuous training (MICT) in people with type 1 diabetes, and 2) whether HIT abolishes acute reductions in plasma glucose observed following MICT sessions. METHODS: Fourteen sedentary individuals with type 1 diabetes (n=7 per group) completed six weeks of HIT or MICT 3 times per week. Pre- and post training measurements were made of 24h interstitial glucose profiles (using continuous glucose monitors (CGMS)) and cardio-metabolic health markers (VO2peak, blood lipid profile and aortic pulse wave velocity; aPWV). Capillary blood glucose concentrations were assessed before and after exercise sessions throughout the training programme to investigate changes in blood glucose during exercise in the fed state. RESULTS: Six weeks of HIT or MICT increased VO2peak by 14% and 15%, respectively (P<0.001), and aPWV by 12% (P<0.001), with no difference between groups. 24h CGMS data revealed no differences in incidence or percentage of time spent in hypoglycaemia following training in either group (P>0.05). In the fed state, the mean change in capillary blood glucose concentration during the HIT sessions was -0.2+/-0.5 mmol/L, whereas blood glucose change was -5.5+/-0.4 mmol/L during MICT. CONCLUSIONS: Six weeks of HIT improved VO2peak and aortic PWV to a similar extent as MICT. The finding that blood glucose remained stable during HIT in the fed state, but consistently fell during MICT, suggests that HIT may be the preferred training mode for some people with type 1 diabetes.

PMID- 30281097 TI - Caring for veterans in US civilian primary care: qualitative interviews with primary care providers. AB - Background: Non-VA health care providers in the USA have been called upon to screen patients for veteran status as a means to better identify military-related health sequelae. Despite this recognized need, many service members are still not being asked about veteran status. Objective: The purpose of this research was to qualitatively assess, from non-VA primary care providers' point-of-view, barriers to providing care to veterans, the training providers perceive as most useful and the tools and translational processes they think would be most valuable in increasing military cultural competency. Methods: Semi-structured qualitative interviews, with non-VA primary care providers (N = 10) as part of a larger quantitative study of primary care providers' attitudes around veteran care. Interviews asked about providers' approach to addressing veteran status in their practice and their thoughts on how to address the needs of this population. Qualitative data were analyzed using a thematic content analysis approach. Results: Three major themes were identified: (i) barriers to caring for patients who are identified as veterans, (ii) thoughts on tools that might help better identify and screen veteran patients and (iii) thoughts on translating and implementing new care processes for veteran patients into everyday practice. Conclusions: Our study identified barriers related to non-VA providers' ability to care for veterans among their patients and possible mechanisms for improving recognition of veterans in civilian health care settings. There is a need for further research to understand how assessment, screening and follow up care for veteran patients is best implemented into civilian primary care settings.

PMID- 30281099 TI - Genome-wide meta-analysis identifies BARX1 and EML4-MTA3 as new loci associated with infantile hypertrophic pyloric stenosis. AB - Infantile hypertrophic pyloric stenosis (IHPS) is a disorder of young infants with a population incidence of ~2/1000 live births, caused by hypertrophy of the pyloric sphincter smooth muscle. Reported genetic loci associated with IHPS explain only a minor proportion of IHPS risk. To identify new risk loci, we carried out a genome-wide meta-analysis on 1395 surgery-confirmed cases and 4438 controls, with replication in a set of 2427 cases and 2524 controls. We identified and replicated six independent genomic loci associated with IHPS risk at genome wide significance (P<5x10-8), including novel associations with two SNPs. One of these SNPs, rs6736913 (odds ratio [OR] = 2.32; P = 3.0x10-15), is a low frequency missense variant in EML4 at 2p21. The second SNP, rs1933683 (OR = 1.34; P = 3.1*10-9) is 1 kb downstream of BARX1 at 9q22.32, an essential gene for stomach formation in embryogenesis. Using the genome-wide complex trait analysis (GCTA) method, we estimated the IHPS SNP heritability to be 30%, and using the LD score regression method, we found support for a previously reported genetic correlation of IHPS with lipid metabolism. By combining the largest collection of IHPS cases to date (3822 cases), with results generalized across populations of different ancestry, we elucidate novel mechanistic avenues of IHPS disease architecture. PMID- 30281100 TI - Extrapolation of in vitro structural alerts for mutagenicity to the in vivo endpoint. AB - As part of the hazard and risk assessment of chemicals in man, it is important to assess the ability of a chemical to induce mutations in vivo. Because of the commonalities in the molecular initiating event, mutagenicity in vitro can correlate well to the in vivo endpoint for certain compound classes; however, the difficulty lies in identifying when this correlation holds true. In silico alerts for in vitro mutagenicity may therefore be used as the basis for alerts for mutagenicity in vivo where an expert assessment is carried out to establish the relevance of the correlation. Taking this into account, a data set of publicly available transgenic rodent gene mutation assay data, provided by the National Institute of Health Sciences of Japan, was processed in the expert system Derek Nexus against the in vitro mutagenicity endpoint. The resulting predictivity was expertly reviewed to assess the validity of the observed correlations in activity and mechanism of action between the two endpoints to identify suitable in vitro alerts for extension to the in vivo endpoint. In total, 20 alerts were extended to predict in vivo mutagenicity, which has significantly improved the coverage of this endpoint in Derek Nexus against the data set provided. Updating the Derek Nexus knowledge base in this way led to an increase in sensitivity for this data set against this endpoint from 9% to 66% while maintaining a good specificity of 89%.

AB - Background: The consumption of unhealthy "Western" dietary patterns has been previously associated with depressive symptoms in different populations. Objective: We examined whether high-sugar and high-saturated-fat dietary patterns are associated with depressive symptoms over 5 y in a British cohort of men and women. Methods: We used data from the Whitehall II study in 5044 individuals (aged 35-55 y). Diet was assessed at phase 7 (2003-2004) using a validated food frequency questionnaire. Dietary patterns were derived by using reduced rank regression with sugar, saturated fat, and total fat as response variables. The Center for Epidemiological Studies-Depression (CES-D) scale was used to assess depressive symptoms (CES-D sum score >=16 and/or use of antidepressant medication) at phase 7 and at phase 9 (2008-2009). We applied logistic regression analyses to test the association between dietary patterns and depressive symptoms. All analyses were stratified by sex. Results: In total, 398 cases of recurrent and 295 cases of incident depressive symptoms were observed. We identified 2 dietary patterns: a combined high-sugar and high-saturated-fat (HSHF) and a high-sugar dietary pattern. No association was observed between the dietary patterns and either incidence of or recurrent depressive symptoms in men or women. For example, higher consumption of the HSHF dietary pattern was not associated with recurrent depressive symptoms in men (model 3, quartile 4: OR: 0.67; 95% CI: 0.36, 1.23; P-trend = 0.13) or in women (model 3, quartile 4: OR: 1.26; 95% CI: 0.58, 2.77; P-trend = 0.97). Conclusion: Among middle-aged men and women living in the United Kingdom, dietary patterns containing high amounts of sugar and saturated fat are not associated with new onset or recurrence of depressive symptoms. PMID- 30281106 TI - Compared with Cow Milk, a Growing-Up Milk Increases Vitamin D and Iron Status in Healthy Children at 2 Years of Age: The Growing-Up Milk-Lite (GUMLi) Randomized Controlled Trial. AB - Background: Iron deficiency (ID) and vitamin D deficiency (VDD) are significant pediatric health issues in New Zealand and Australia and remain prevalent micronutrient deficiencies in young children globally. Objective: We aimed to investigate the effect of a micronutrient-fortified, reduced-energy growing-up milk (GUMLi) compared with cow milk (CM) consumed for 1 y on dietary iron and vitamin D intakes and the status of New Zealand and Australian children at 2 y of age. Methods: The GUMLi Trial was a multicenter, double-blind, randomized controlled trial in 160 healthy 1-y-old New Zealand and Australian children conducted in 2015-2017. Participants were randomly assigned 1:1 to receive GUMLi (1.7 mg Fe/100 mL; 1.3 ug cholecalciferol/100 mL) or CM (0.02 mg Fe/100 mL; 0.06 ug cholecalciferol/100 mL) for 12 mo. Secondary outcomes, reported here, included change in dietary iron and vitamin D intakes, iron status, and 25-hydroxyvitamin D [25(OH)D] concentrations from blood samples at age 2 y. All regression models were adjusted for baseline outcome and study center. Results: GUMLi was a large contributor to dietary intakes of iron and vitamin D after 12 mo when compared with intakes from food and CM. The adjusted mean difference between groups for serum ferritin concentrations was 17.8 ug/L (95% CI: 13.6, 22.0 ug/L; P < 0.0001), and for 25(OH)D it was 16.6 nmol/L (95% CI: 9.9, 23.3 nmol/L; P < 0.0001). After 12 mo, ID was present in 16 (24%) participants in the CM group and 5 (7%) participants in the GUMLi group (P = 0.009), and the prevalence of VDD in the CM group increased to 14% (n = 10) and decreased to 3% (n = 2) (P = 0.03) in the GUMLi group. Conclusion: In comparison with CM, GUMLi significantly improved dietary iron and vitamin D intakes and the iron and vitamin D status of healthy children at 2 y of age. This trial was registered with the Australian New Zealand Clinical Trials Registry (www.anzctr.org.au) as ACTRN12614000918628.

PMID- 30281112 TI - Hepatic Expression of PEMT, but Not Dietary Choline Supplementation, Reverses the Protection against Atherosclerosis in Pemt-/-/Ldlr-/- Mice. AB - Background: Phosphatidylethanolamine N-methyltransferase (PEMT) converts phosphatidylethanolamine to phosphatidylcholine. Pemt-/-/low density lipoprotein receptor (Ldlr)-/- mice have significantly reduced plasma lipids and are protected against atherosclerosis. Recent studies have shown that choline can be metabolized by the gut flora into trimethylamine-N-oxide (TMAO), which is an emerging risk factor for atherosclerosis. Objective: The objective of this study was to determine whether ectopic hepatic PEMT expression or choline supplementation would promote atherosclerosis in Pemt-/-/Ldlr-/- mice. Methods: Male 8- to 10-wk-old Pemt+/+/Ldlr-/- (SKO) and Pemt-/-/Ldlr-/- (DKO) mice were injected with an adeno-associated virus (AAV) expressing green fluorescent protein (GFP) or human PEMT and fed a Western diet (40% of calories from fat, 0.5% cholesterol) for 8 wk. In a separate experiment, 8- to 10-wk-old SKO and half of the DKO male mice were fed a Western diet with normal (3 g/kg) choline for 12 wk. The remaining DKO mice [choline-supplemented (CS) DKO] were fed a CS Western diet (10 g choline/kg). Plasma lipid concentrations, choline metabolites, and aortic atherosclerosis were measured. Results: Plasma cholesterol, plasma TMAO, and aortic atherosclerosis were reduced by 60%, 40%, and 80%, respectively, in DKO mice compared with SKO mice. AAV-PEMT administration increased plasma cholesterol and TMAO by 30% and 40%, respectively, in DKO mice compared with AAV GFP-treated DKO mice. Furthermore, AAV-PEMT-injected DKO mice developed atherosclerotic lesions similar to SKO mice. In the second study, there was no difference in atherosclerosis or plasma cholesterol between DKO and CS-DKO mice. However, plasma TMAO concentrations were increased 2.5-fold in CS-DKO mice compared with DKO mice. Conclusions: Reintroducing hepatic PEMT reversed the atheroprotective phenotype of DKO mice. Choline supplementation did not increase atherosclerosis or plasma cholesterol in DKO mice. Our data suggest that plasma TMAO does not induce atherosclerosis when plasma cholesterol is low. Furthermore, this is the first report to our knowledge that suggests that de novo choline synthesis alters TMAO status.

PMID- 30281114 TI - Intravenous Triacylglycerol Infusion Promotes Ceramide Accumulation and Hepatic Steatosis in Dairy Cows. AB - Background: Increased plasma free fatty acids (FFAs) impair insulin sensitivity in dairy cows via unknown mechanisms. In nonruminants, saturated FFAs upregulate the hepatic synthesis and secretion of ceramide, which inhibits insulin action. Objective: We aimed to determine whether an increase in plasma FFAs promotes hepatic and plasma ceramide accumulation in dairy cows. Methods: Six nonpregnant, nonlactating Holstein cows were used in a study with a crossover design and treatments consisting of intravenous infusion of either saline (control) or triacylglycerol emulsion (TG; 20 g/h) for 16 h. The feeding level was set at 120% of energy requirements. Blood was collected at regular intervals and liver was biopsied at 16 h. Ceramides, monohexosylceramides (Glc/Gal-Cer), lactosylceramides (LacCer), and sphingomyelins (SMs) in plasma and liver were profiled. Hepatic expression of ceramide synthases was determined. Data were analyzed with the use of mixed models, regressions, and Spearman rank correlations. Results: After 16 h of infusion, plasma FFA concentrations were >5 fold and liver triacylglycerol concentrations were 4-fold greater in TG cows, relative to control. Plasma total and very long-chain ceramide (e.g., C24:0 ceramide) concentrations increased ~4-fold in TG over control by hour 16 of infusion, while C16:0-ceramide were not modified by TG. Infusion of TG increased plasma Glc/Gal-Cer (e.g., C16:0-Glc/Gal-Cer, 4-fold by hour 16) relative to control, but did not alter LacCer or SM concentrations. Hepatic ceramide concentrations increased with TG relative to control (e.g., C24:0-ceramide by 1.7 fold). Hepatic expression of ceramide synthase 2 was 60% greater after TG infusion compared with the control. Circulating ceramides were related to circulating FFA and hepatic triacylglycerol concentrations (e.g., C24:0-ceramide, rho = 0.73 and 0.80, respectively; P < 0.001). Conclusion: Hepatic ceramide synthesis is associated with elevations in circulating FFAs and hepatic triacylglycerol during the induction of hyperlipidemia in dairy cows. This work supports the emerging evidence for the role of ceramide during hepatic steatosis and insulin antagonism in cows.

PMID- 30281126 TI - Chronic inflammation in end-stage renal disease and dialysis. AB - Under normal conditions, inflammation is a protective and physiological response to various harmful stimuli. However, in several chronic debilitating disorders, such as chronic kidney disease, inflammation becomes maladaptive, uncontrolled and persistent. Systemic persistent inflammation has, for almost 20 years, been recognized as a major contributor to the uraemic phenotype (such as cardiovascular disease, protein energy wasting, depression, osteoporosis and frailty), and a predictor of cardiovascular and total mortality. Since inflammation is mechanistically related to several ageing processes (inflammageing), it may be a major driver of a progeric phenotype in the uraemic milieu. Inflammation is likely the consequence of a multifactorial aetiology and interacts with a number of factors that emerge when uraemic toxins accumulate. Beside interventions aiming to decrease the production of inflammatory molecules in the uraemic milieu, novel strategies to increase the removal of large middle molecules, such as expanded haemodialysis, may be an opportunity to decrease the inflammatory allostatic load associated with retention of middle molecular weight uraemic toxins. PMID- 30281127 TI - Expanded haemodialysis: news from the field. AB - Expanded haemodialysis (HDx) has emerged as a promising solution to improve haemodialysis effectiveness. A medium cut-off membrane allows the removal of a wider range of uraemic toxins. However, little is known about the potential interesting applications of HDx therapy. Feedback from the first routine use of HDx therapy under real-life conditions in European facilities was excellent for priming and rinse back. There was no adverse event after 5191 HDx treatments. Patients suffering from itching, restless legs syndrome, persistent asthenia or malnourishment could benefit from HDx therapy. Moreover, we discuss here the promising applications in which HDx could be valuable (myeloma, rhabdomyolysis or cardiovascular diseases). This enthusiastic message is mitigated by reminding why and how prudence should be taken in the design of future HDx studies. PMID- 30281128 TI - Clinical evidence on haemodiafiltration. AB - Haemodiafiltration (HDF) combines diffusive and convective solute removal in a single treatment session. HDF provides a greater removal of higher molecular weight uraemic retention solutes than conventional high-flux haemodialysis (HD). Recently completed randomized clinical trials suggest better patient survival with online HDF. The treatment is mainly used in Europe and Japan. This review gives a brief overview of the presently available evidence of the effects of HDF on clinical end points, it speculates on possible mechanisms of a beneficial effect of HDF as compared with standard HD and ends with some perspectives for the future. PMID- 30281129 TI - Current approaches to middle molecule removal: room for innovation. AB - Aggressive removal of middle molecules or larger low-molecular-weight proteins (LMWPs) has been a growing concern following studies on their harmful effects on the mortality and morbidity of chronic dialysis patients. To remove larger LMWPs and some protein-bound uremic toxins (PBUTs), high- and medium-cutoff (HCOs and MCOs, respectively) membranes, convective therapy and protein adsorptive membranes are available. When we use HCO or MCO membranes for convective therapy, we have to take care to avoid massive albumin leakage during a dialysis session. Convection volume is an important element to increase middle molecule removal; however, a larger convection volume has a risk of larger leakage of albumin. Predilution hemodiafiltration is a useful measurement to increase larger LMWPs without massive albumin leakage. beta2-microglobulin (B2M), alpha1-microglobulin (A1M) and albumin leakage during a dialysis session are useful parameters for assessing middle-molecule removal. Reduction ratios of B2M >80% and of A1M >35% are favorable to improve severe dialysis-related symptoms. The efficacy of middle molecule removal should be evaluated in comparison with clinical outcomes, mortality, morbidity and the improvement of dialysis-related symptoms. Recently some dialysis-related symptoms such as sleep disturbance, skin itchiness and dialysis hypotension have been recognized as good surrogate makers for mortality. Further studies to evaluate the relationship between middle molecule or PBUTs removal and the improvement of patient symptoms should be performed in well designed randomized controlled trials. PMID- 30281130 TI - Membrane innovation: closer to native kidneys. AB - Modern methods in analytical biochemistry have established that uraemia is associated with the retention of proteins, both in their native state and post translationally modified, over a wide range of molecular weights up to 60 kDa. Evidence is accumulating that these higher molecular weight retention solutes are important uraemic toxins, and therapies such as online haemodiafiltration (HDF), which enhance their removal, are associated with improved outcomes. However, HDF has limitations regarding cost, clinical implementation and the need for an external source of sterile substitution solution to maintain fluid balance. New membranes that have a solute removal profile more closely approaching that of the glomerular filtration barrier when used for conventional haemodialysis, while at the same time not allowing the passage of clinically significant amounts of beneficial proteins, are needed to address these limitations. Tighter control of the molecular characteristics of the polymers used for membrane fabrication, along with the introduction of additives and improvements in the manufacturing process, has led to membranes with a tighter pore size distribution that allows the use of an increased absolute pore size without leaking substantial amounts of albumin. At the same time, the wall thickness and internal diameter of membrane fibres have been decreased, enhancing convective transport within the dialyser without the need for an external source of substitution solution. These new expanded range membranes provide a solute removal profile more like that of the native kidney than currently available membranes when used in conventional haemodialysis. PMID- 30281131 TI - Large uremic toxins: an unsolved problem in end-stage kidney disease. AB - Patients with end-stage kidney disease (ESKD) on maintenance hemodialysis are subject to a high burden of inflammation and cardiovascular disease, driven at least in part by retention of uremic solutes. Existing dialysis technologies using high-flux membranes offer limited clearance of solutes >15 kDa. New approaches to improve the removal of large uremic toxins include the novel medium cut-off dialysis membranes with pores larger than those in high-flux membranes. These new membranes provide the potential to improve the clearance of large middle molecules up to 50 kDa. In this review, we discuss 18 uremic toxins with molecular weights between 15 and 60 kDa that are retained in ESKD, for which there is evidence of a link to inflammation and/or cardiovascular disease. These include inflammatory proteins, cytokines, adipokines and other signaling proteins. Improved clearance of this group of difficult to remove molecules has the potential to lead to improved outcomes in dialysis patients by reducing the burden of cardiovascular disease, which now needs to be assessed in robust clinical trials. PMID- 30281132 TI - Cardiovascular disease in dialysis patients. AB - Cardiovascular disease (CVD) is a highly common complication and the first cause of death in patients with end-stage renal disease (ESRD) on haemodialysis (HD). In this population, mortality due to CVD is 20 times higher than in the general population and the majority of maintenance HD patients have CVD. This is likely due to ventricular hypertrophy as well as non-traditional risk factors, such as chronic volume overload, anaemia, inflammation, oxidative stress, chronic kidney disease-mineral bone disorder and other aspects of the 'uraemic milieu'. Better understanding the impact of these numerous factors on CVD would be an important step for prevention and treatment. In this review we focus non-traditional CVD risk factors in HD patients. PMID- 30281133 TI - From old uraemic toxins to new uraemic toxins: place of 'omics'. AB - Uraemic toxins seem to play an important role in the genesis of cardiovascular and renal damage in chronic kidney disease patients. This short article is divided into two thematic sections. The first part focuses on a selection of 'old' toxins for which recent data (published between 2016 and 2018) have provided a better understanding of the associated harmful mechanisms and which, in our opinion, nephrologists should be more aware of. The second part highlights new perspectives for identifying and quantifying these compounds using 'omics' techniques.

PMID- 30281134 TI - Expanded haemodialysis: from operational mechanism to clinical results. AB - Recent advances in chemical composition and new production techniques resulted in improved biocompatibility and permeability of dialysis membranes. Among these, the creation of a new class of membranes called medium cut-off (MCO) represents an important step towards improvement of clinical outcomes. Such membranes have been developed to improve the clearance of medium to high molecular weight (MW) solutes (i.e. uraemic toxins in the range of 5-50 kDa). MCO membranes have peculiar retention onset and cut-off characteristics. Due to a modified sieving profile, MCO membranes have also been described as high-retention onset. The significant internal filtration achieved in MCO haemodialysers provides a remarkable convective clearance of medium to high MW solutes. The marginal loss of albumin observed in MCO membranes compared with high cut-off membranes is considered acceptable, if not beneficial, producing a certain clearance of protein-bound solutes. The application of MCO membranes in a classic dialysis modality characterizes a new technique called expanded haemodialysis. This therapy does not need specific software or dedicated hardware, making its application possible in every setting where the quality of dialysis fluid meets current standards.

AB - Treatment of alopecia totalis and alopecia universalis is often challenging and unsatisfactory. Recently, Janus kinase inhibitor has shown promising results. The aim of this study is to compare the efficacy and tolerability of oral tofacitinib and conventional modalities for treating refractory alopecia totalis/universalis. A total of 74 patients (18 treated with tofacitinib, 26 treated with conventional oral treatment (steroid +/- cyclosporine), and 30 treated with diphenylcyclopropenone) were included in the study. The patients' medical records were reviewed retrospectively. After 6 months, 44.4% of patients in the tofacitinib group, 37.5% in the conventional oral treatment group, and 11.1% in the diphenylcyclopropenone group achieved 50% improvements in the Severity of Alopecia Tool score. During treatment, 10% of patients in the tofacitinib group, 73.1% in the conventional oral treatment group, and 10% in the diphenylcyclopropenone group experienced adverse drug reactions. In conclusion, oral tofacitinib was more effective than diphenylcyclopropenone immunotherapy and more tolerable than conventional oral treatment after 6 months of treatment.

AB - Conventional treatment of cutaneous leishmaniasis often leaves permanent scars with frequent psychosocial sequelae. The aim of this study was to compare the efficacy, safety, associated pain and final cosmetic outcome of fractional carbon dioxide (CO2) laser followed by topical application of sodium stibogluconate vs. sodium stibogluconate injections for the treatment of cutaneous leishmaniasis. A total of 181 lesions (20 patients) were randomly assigned to receive intralesional injections of sodium stibogluconate (control group) or fractional CO2 laser treatment followed by topical application of sodium stibogluconate (study group). The visual analogue scale (VAS) score of the control group was much higher than that of the study group (6.85 vs. 3.5, respectively, p < 0.001). Both the patients and 2 blinded dermatologists found the final cosmetic outcome to be superior for laser-treated lesions (p = 0.001 vs. p =0.008 for controls). Fractional CO2 laser treatment followed by topical application of sodium stibogluconate is less painful and leads to a better final cosmetic outcome compared with intralesional injections of sodium stibogluconate.

AB - This cross-sectional study evaluated the usefulness of an ultrasound technique in assessment of nail changes in 35 patients with psoriatic onychopathy and 25 with nail dystrophy secondary to onychomycosis. All patients underwent 3 examinations: a complete clinical assessment; a nail ultrasound study; and fungal culture. Nails of patients with psoriatic onychopathy presented a thinner nail plate and nail bed, measured by ultrasound, than did those with onychomycosis. The percentage of patients with a power Doppler signal >=2 at nail bed was significantly higher in psoriatic onychopathy than in onychomycosis, and structural bone lesions were more frequent in psoriatic onychopathy than in onychomycosis. These results suggest that the presence of structural damage and high-power Doppler signal are the main ultrasound findings supporting a diagnosis of psoriatic onychopathy.

AB - OBJECTIVES: To evaluate the association between cataract and cataract surgery and risks of osteoporosis and fracture. DESIGN: Nationwide population-based retrospective cohort study. SETTING: Taiwan's National Health Insurance Research Database. PARTICIPANTS: Individuals with (n=57,972) and without (n=57,972) cataracts. MEASUREMENTS: Individuals with and without cataracts were matched 1:1 for age, sex, and index year. Those with cataracts were further divided into cataract surgery and nonsurgery groups. Incidences and hazard ratios (HR) for risks of developing osteoporosis and fracture were calculated using Cox proportional hazard regression models. RESULTS: During mean follow-up of 6.4 years, 17,450 participants with cataracts and 12,627 without developed osteoporosis or fractures. Having cataracts was significantly associated with risk of developing osteoporosis or fracture (adjusted HR (aHR) = 1.29, 95% confidence interval (CI) = 1.25-1.32, p < .001). In analyses for each event, cataract was significantly associated with greater likelihood of all outcomes (osteoporosis: aHR = 1.43, 95% CI = 1.37-1.50, p < .001; hip fracture: aHR = 1.16, 95% CI = 1.07-1.26, p < .001; vertebral fracture: (aHR = 1.25, 95% CI = 1.18-1.33, p < .001; other fractures: aHR = 1.24, 95% CI = 1.20-1.28, p < .001). Participants who underwent cataract surgery were at significantly lower risk of osteoporosis or fracture (aHR = 0.58, 95% CI = 0.56-0.59, p < .001), than those who did not. Undergoing cataract surgery was also associated with lower risks of all individual events (osteoporosis; hip, vertebral, other fracture). CONCLUSION: Cataract was independently associated with increased risks of osteoporosis and fracture. There might be an association between cataract surgery and lower risks of osteoporosis and fracture. PMID- 30281144 TI - Is there a burden attached to synaesthesia? Health screening of synaesthetes in the general population. AB - Synaesthesia has long been considered a benign alternative form of perception most often associated with positive rather than negative outcomes. The condition has been associated with a variety of cognitive and perceptual advantages, including benefits in memory, processing speed, and creativity. It is not currently recognized in the DSM-IV. Recently, however, several studies have raised the question of a possible link between synaesthesia and clinical conditions. Here, we present the first large-scale screening of the general population in which we (1) objectively identified grapheme-colour synaesthetes and (2) elicited information from our participants about a range of clinical conditions. We compared the prevalence rates of these conditions in synaesthetes versus non-synaesthetes to establish whether any conditions were found at a higher rate among synaesthetes. In our initial study, screening 3,742 people (95 synaesthetes and 3,647 controls), we found initially that grapheme-colour was significantly comorbid with two conditions (anxiety disorder and obsessive compulsive disorder). In our second study, screening a new population of 120 synaesthetes and 166 non-synaesthetes, we replicated our finding that grapheme colour synaesthesia is comorbid with anxiety disorder. At the same time, we also addressed a methodological concern that likely elevated rates of OCD in Study 1. We consider the aetiology of synaesthesia to determine whether there may be a shared genetic or neurological basis with anxiety disorder, and we question the status of synaesthesia within a mental health framework. PMID- 30281146 TI - Northern areas as refugia for temperate species under current climate warming: Atlantic salmon (Salmo salar L.) as a model in northern Europe. AB - In this work, patterns of geographical genetic diversity in Atlantic salmon Salmo salar were studied across the whole Atlantic Arc; whether these patterns (and thus genetic population structure) were affected by water temperatures was also evaluated. Salmo salar populations were characterized using microsatellite loci and then analysed with reference to ocean surface temperature data from across the region. Analysis showed the presence of a latitudinal cline of genetic variability (higher in northern areas) and water temperatures (sea surface temperatures) determining genetic population structure (the latter in combination with genetic drift in southern populations). Under the current global change scenario, northern areas of Europe would constitute refugia for diversity in the future. This is effectively the inverse of what appears to have happened in glacial refugia during the last glacial maximum. From this perspective, the still abundant and large northern populations S. salar should be considered as precious as the small almost relict southern ones and given appropriate protection. Careful management of the species, coordinated across countries and latitudes, is needed in order to avoid its extinction in Europe.

AB - Genetic introgression from stocked adult northern pike Esox lucius to a wild self recruiting population was detected in a large river system and some stocked E. lucius survived up to two spawning seasons and dispersed over several kilometres in the river. Moreover, the catch rate of stocked E. lucius by anglers was low (9.6%), hence suggesting that the efficiency of stocking activity is questionable. PMID- 30281145 TI - Chemoprevention agents for melanoma: a path forward into phase 3 clinical trials. AB - Recent progress in the treatment of advanced melanoma has led to unprecedented improvements in overall survival and, as these new melanoma treatments have been developed and deployed in the clinic, much has been learned about the natural history of the disease. Now is the time to apply that knowledge toward the design and clinical evaluation of new chemoprevention agents. Melanoma chemoprevention has the potential to reduce dramatically both the morbidity and the high costs associated with treating patients who have metastatic disease. In this work, scientific and clinical melanoma experts from the national Melanoma Prevention Working Group, composed of National Cancer Trials Network investigators, discuss research aimed at discovering and developing (or repurposing) drugs and natural products for the prevention of melanoma and propose an updated pipeline for translating the most promising agents into the clinic. The mechanism of action, preclinical data, epidemiological evidence, and results from available clinical trials are discussed for each class of compounds. Selected keratinocyte carcinoma chemoprevention studies also are considered, and a rationale for their inclusion is presented. These data are summarized in a table that lists the type and level of evidence available for each class of agents. Also included in the discussion is an assessment of additional research necessary and the likelihood that a given compound may be a suitable candidate for a phase 3 clinical trial within the next 5 years. PMID- 30281148 TI - Progressive dissociation of cortical and subcortical network development in children with new-onset juvenile myoclonic epilepsy. AB - OBJECTIVE: Structural and functional magnetic resonance imaging (MRI) studies have consistently documented cortical and subcortical abnormalities in patients with juvenile myoclonic epilepsy (JME). However, little is known about how these structural abnormalities emerge from the time of epilepsy onset and how network interactions between and within cortical and subcortical regions may diverge in youth with JME compared to typically developing children. METHODS: We examined prospective covariations of volumetric differences derived from high-resolution structural MRI during the first 2 years of epilepsy diagnosis in a group of youth with JME (n = 21) compared to healthy controls (n = 22). We indexed developmental brain changes using graph theory by computing network metrics based on the correlation of the cortical and subcortical structural covariance near the time of epilepsy and 2 years later. RESULTS: Over 2 years, normally developing children showed modular cortical development and network integration between cortical and subcortical regions. In contrast, children with JME developed a highly correlated and less modular cortical network, which was atypically dissociated from subcortical structures. Furthermore, the JME group also presented higher clustering and lower modularity indices than controls, indicating weaker modules or communities. The local efficiency in JME was higher than controls across the majority of cortical nodes. Regarding network hubs, controls presented a higher number than youth with JME that were spread across the brain with ample representation from the different modules. In contrast, children with JME showed a lower number of hubs that were mainly from one module and comprised mostly subcortical structures. SIGNIFICANCE: Youth with JME prospectively developed a network of highly correlated cortical regions dissociated from subcortical structures during the first 2 years after epilepsy onset. The cortical-subcortical network dissociation provides converging insights into the disparate literature of cortical and subcortical abnormalities found in previous studies. PMID- 30281149 TI - Genomic and transcriptomic characterisation of undifferentiated pleomorphic sarcoma of bone. AB - Undifferentiated pleomorphic sarcoma of bone (UPSb), is a rare primary bone sarcoma that lacks a specific line of differentiation. There is very little information about the genetic alterations leading to tumourigenesis or malignant transformation. Distinguishing between UPSb and other malignant bone sarcomas, including dedifferentiated chondrosarcoma and osteosarcoma, can be challenging due to overlapping features. To explore the genomic and transcriptomic landscape of UPSb tumours, whole-exome sequencing (WES) and RNA Sequencing (RNA-Seq) were performed on UPSb tumours. All tumours lacked hotspot mutations in IDH1/2 132 or 172 codons, thereby excluding the diagnosis of dedifferentiated chondrosarcoma. Recurrent somatic mutations in TP53 were identified in 4/14 samples (29%). Moreover, recurrent mutations in histone chromatin remodelling genes, including H3F3A, ATRX and DOT1L, were identified in 5/14 samples (36%), highlighting the potential role of deregulated chromatin remodelling pathways in UPSb tumourigenesis. The majority of recurrent mutations in chromatin remodelling genes identified here are reported in COSMIC, including the H3F3A G35 and K36 hotspot residues. Copy number alteration analysis identified gains and losses in genes that have been previously altered in UPSb or UPS of soft tissue. Eight somatic gene fusions were identified by RNA-Seq, two of which, CLTC-VMP1 and FARP1-STK24, were reported previously in multiple cancers. Five gene fusions were genomically characterised. Hierarchical clustering analysis, using RNA-Seq data, distinctly clustered UPSb tumours from osteosarcoma and other sarcomas, thus molecularly distinguishing UPSb from other sarcomas. RNA-Seq expression profiling analysis and quantitative RT-PCR showed an elevated expression in FGF23 which can be a potential molecular biomarker in UPSb. To our knowledge, this study represents the first comprehensive WES and RNA-Seq analysis of UPSb tumours revealing novel protein-coding recurrent gene mutations, gene fusions and identifying a potential UPSb molecular biomarker, thereby broadening the understanding of the pathogenic mechanisms and highlighting the possibility of developing novel targeted therapeutics. PMID- 30281150 TI - Increased sensitivity of the circadian system to light in delayed sleep-wake phase disorder. AB - KEY POINTS: This is the first study to demonstrate an altered circadian phase shifting response in a circadian rhythm sleep disorder. Patients with delayed sleep-wake phase disorder (DSWPD) demonstrate greater sensitivity of the circadian system to the phase-delaying effects of light. Increased circadian sensitivity to light is associated with later circadian timing within both control and DSWPD groups. DSWPD patients had a greater sustained pupil response after light exposure. Treatments for DSWPD should consider sensitivity of the circadian system to light as a potential underlying vulnerability, making patients susceptible to relapse. ABSTRACT: Patients with delayed sleep-wake phase disorder (DSWPD) exhibit delayed sleep-wake behaviour relative to desired bedtime, often leading to chronic sleep restriction and daytime dysfunction. The majority of DSWPD patients also display delayed circadian timing in the melatonin rhythm. Hypersensitivity of the circadian system to phase-delaying light is a plausible physiological basis for DSWPD vulnerability. We compared the phase shifting response to a 6.5 h light exposure (~150 lux) between male patients with diagnosed DSWPD (n = 10; aged 20.8 +/- 2.3 years) and male healthy controls (n = 11; aged 22.4 +/- 3.3 years). Salivary dim light melatonin onset (DLMO) was measured under controlled conditions in dim light (<3 lux) before and after light exposure. Correcting for the circadian time of the light exposure, DSWPD patients exhibited 31.5% greater phase delay shifts than healthy controls. In both groups, a later initial melatonin phase was associated with a greater magnitude phase shift, indicating that increased circadian sensitivity to light may be a factor that contributes to delayed phase, even in non-clinical groups. DSWPD patients also had reduced pupil size following the light exposure, and showed a trend towards increased melatonin suppression during light exposure. These findings indicate that, for patients with DSWPD, assessment of light sensitivity may be an important factor that can inform behavioural therapy, including minimization of exposure to phase-delaying night-time light. PMID- 30281151 TI - Gastrointestinal effects following acupuncture at Pericardium-6 and Stomach-36 in healthy dogs: a pilot study. AB - OBJECTIVES: To quantify changes in gastric and intestinal emptying times in the conscious dog following gastrointestinal acupoint stimulation. MATERIALS AND METHODS: In a randomised, blinded crossover study, six dogs were fed 30*1.5 mm barium-impregnated polyethylene spheres and underwent: (1) no acupuncture (Control); (2) stimulation of target points PC6 and ST36 (Target) and (3) stimulation of non-target points LU7 and BL55 (Sham). Abdominal radiographs were assessed immediately after feeding the spheres and every hour for 12 hours and their number in the stomach and large intestines was counted. RESULTS: The number of barium-impregnated polyethylene spheres found distal to the stomach was less in the Target group compared to the Control and Sham groups between hours 2 and 4, but no differences between groups were seen for the remainder of the treatment period. The number of spheres found within the colon/rectum was less in the Target group compared to the Control and Sham groups between hours 4 and 6, and compared to the Sham group only at hour 7 but no differences between groups were seen after hour 8. CLINICAL SIGNIFICANCE: Acupuncture targeted at the gastrointestinal tract of dogs was associated briefly with slowed gastric emptying and gastrointestinal transit time. This foundational study lays the groundwork for additional studies of acupuncture effects associated with altered physiologic states. PMID- 30281152 TI - QRICH1 mutations cause a chondrodysplasia with developmental delay. AB - In many children with short stature, the etiology of the decreased linear growth remains unknown. We sought to identify the underlying genetic etiology in a patient with short stature, irregular growth plates of the proximal phalanges, developmental delay, and mildly dysmorphic facial features. Exome sequencing identified a de novo, heterozygous, nonsense mutation (c.1606C>T:p.R536X) in QRICH1. In vitro studies confirmed that the mutation impaired expression of the QRICH1 protein. SiRNA-mediated knockdown of Qrich1 in primary mouse epiphyseal chondrocytes caused downregulation of gene expression associated with hypertrophic differentiation. We then identified an unrelated individual with another heterozygous de novo nonsense mutation in QRICH1 who had a similar phenotype. A recently published study identified QRICH1 mutations in three patients with developmental delay, one of whom had short stature. Our findings indicate that QRICH1 mutations cause not only developmental delay but also a chondrodysplasia characterized by diminished linear growth and abnormal growth plate morphology due to impaired growth plate chondrocyte hypertrophic differentiation. PMID- 30281153 TI - Sex differences in adolescent physical aggression: Evidence from sixty-three low and middle-income countries. AB - A great deal of research shows that adolescent and adult males are more likely to engage in physical aggression and violence than females are. However, few studies have examined cross-cultural variation in sex differences, particularly among low and middle-income countries [LMICs]. Based on social role and sexual selection theories, we derived two hypotheses regarding possible variations in sex differences across societal contexts: 1) sex differences increase with societal gender polarization (social role theory) and 2) sex differences are exacerbated in societies where socio-economic opportunities are scarce, unequal, or insecure (prediction derived from sexual selection theory). The current study examined the prevalence of and variation in sex differences in physical aggression, as measured by frequent fighting, among 247,909 adolescents in 63 low- and middle income countries. The results show that, overall, males were over twice as likely (OR = 2.68; 95% CI = 2.60-2.76) to report frequent fighting in the past 12 months than females. However, sex differences vary significantly across LMICs, wherein countries with higher female prevalence rates have smaller sex differences in frequent fighting. Contrary to expectations derived from social role theory, sex differences in physical aggression decrease as societal gender inequality increased. In regards to sexual selection theory, we find no evidence that sex differences in frequent fighting varies according to societal rule of law or income inequality. PMID- 30281154 TI - miR-191 modulates B-cell development and targets transcription factors E2A, Foxp1, and Egr1. AB - The interdependence of posttranscriptional gene regulation via miRNA and transcriptional regulatory networks in lymphocyte development is poorly understood. Here, we identified miR-191 as direct upstream modulator of a transcriptional module comprising the transcription factors Foxp1, E2A, and Egr1. Deletion as well as ectopic expression of miR-191 resulted in developmental arrest in B lineage cells, indicating that fine tuning of the combined expression levels of Foxp1, E2A, and Egr1, which in turn control somatic recombination and cytokine-driven expansion, constitutes a prerequisite for efficient B-cell development. In conclusion, we propose that miR-191 acts as a rheostat in B-cell development by fine tuning a key transcriptional program. PMID- 30281155 TI - MYC-driven malignant transformation of mature murine B cells requires inhibition of both intrinsic apoptosis and p53 activity. AB - Increased expression of the oncogene MYC is a common feature of many B-cell malignancies, however MYC overexpression by itself is not sufficient for transformation, and additional genetic events are required, although the exact nature of these remains unknown. In patients and in transgenic mouse models, oncogenic transformation may occur in B cells at various differentiation stages interacting with complex microenvironments. B-cell oncogenesis often occurs after prolonged periods of time, making it difficult to accurately identify the genetic events required for transformation. An in vitro system, where malignant transformation of primary B cells could be analyzed, would facilitate the identification of genetic events required for transformation. Here, we describe such a system and show that primary murine B cells rapidly become transformed upon forced expression of MYC, in conjunction with simultaneous inhibition of the ARF/p53 axis via overexpression of BMI1, as well as through downregulation of p19ARF or expression of a dominant-negative p53 and suppression of intrinsic apoptosis through overexpression of BCLXL or MCL1. Established tumor cells remained addicted to expression of the lymphoma-inducing genes. In mice, transformed cells rapidly established fatal B-cell lymphomas. Our results suggest that transformation of normal mature B cells into lymphomas can occur as a consequence of three defined events.

AB - BACKGROUND: Cryopreserved platelets (CPPs) are considered a promising approach for extended platelet storage, bridging inventory shortages of conventionally stored platelets. It is unknown if platelet concentrates exposed to photochemical treatment (PCT) with amotosalen and ultraviolet A (UVA) light, to inactivate pathogens, are suitable for freezing. The objective of this study was to analyze potential effects of PCT on CPPs as compared with untreated CPPs. STUDY DESIGN AND METHODS: A total of 12 PCT-treated and 12 untreated platelet units from buffy coats were cryopreserved at -80 degrees C in 5% dimethyl sulfoxide. CPPs of both types were rapidly thawed at 37 degrees C and resuspended in 200 mL fresh plasma. In vitro properties were analyzed prefreezing, postfreezing and thawing, and on Day 1 after thawing. RESULTS: Directly after thawing, no major differences in platelet content, lactase hydrogenase, adenosine triphosphate, mitochondrial membrane potential, CD62P, CD42b, and platelet endothelial cell adhesion molecule were seen between PCT-CPPs and conventional CPPs. Agonist-induced PAC-1 expression and contribution of CPPs to blood coagulation in an experimental rotational thromboelastometry setup were also similar between the groups. On Day 1 after thawing, the CPPs of both types performed less well. The PCT-CPPs tended to be more affected by the freezing process than the conventional CPPs. CONCLUSIONS: PCT-CPPs appeared slightly more susceptible to lesion effects by freezing than conventional CPPs, in particular in assays on Day 1 after thawing, but these differences were small relative to the dramatic effects of the freezing process itself. PMID- 30281157 TI - Stronger effects of heterozygosity on survival in harsher environments. AB - The hypothesis that the effects of heterozygosity vary with environmental conditions was tested using six populations of marble trout Salmo marmoratus from western Slovenia as a model system. The hypotheses tested were: stronger effects of heterozygosity on survival in populations characterized by low average survival; no effects of heterozygosity on probability of surviving flash floods owing to their largely non-selective effects across traits; stronger effects of heterozygosity on survival for fish born after floods than fish born before. A significant effect of heterozygosity on survival was found in populations characterized by low average survival. There were no effects of heterozygosity on probability of surviving flash floods, but in one population a positive correlation between heterozygosity and survival for fish born after the extreme events was found, probably because crowding in a small section of the stream caused more intense competition for resources.

AB - In this study, a full-sib population of Ctenopharyngodon idella was constructed and approximately 500 C. idella individuals were sampled at four early developmental stages (hatching, first feeding, juvenile fish and young fish). Four DNA pools were constructed and subjected to next-generation sequencing. On the basis of the identification of single nucleotide polymorphisms (SNP), changes in gene and genotype frequencies during the developmental progress of C. idella were revealed, which indicates that death during the early developmental stage is not a random process. These findings will establish the basis for further studies performed for identifying superior alleles or genotypes as target markers for molecular breeding. PMID- 30281159 TI - Seasonal aggregation and diel activity by the sicklefin devil ray Mobula tarapacana off a small, equatorial outcrop of the Mid-Atlantic Ridge. AB - The present study aimed to analyse occurrence patterns, relative abundance and habitat use by the sicklefin devil ray Mobula tarapacana in the Saint Peter and Saint Paul Archipelago (SPSPA), Brazil, located in the Mid-Atlantic Ridge. Sampling was conducted between December 2008 and December 2012 by surface surveys and tagging with conventional tags and acoustic transmitters. Mobula tarapacana were sighted in the SPSPA year round but the highest frequency of occurrence was observed from January to June, probably due to greater food availability during this season. However, M. tarapacana might also use the area for reproductive purposes based on evidence of mating behaviour. The residency period of tagged rays measured by three autonomous acoustic receivers deployed around SPSPA spanned from 1 to 74 days with most of the detections occurring during daytime. These results suggest that the SPSPA could be an ecologically-important aggregation area for M. tarapacana, possibly providing the species with a feeding or resting habitat while transiting in the equatorial Atlantic Ocean. PMID- 30281160 TI - Vacuum-driven fluid manipulation by a piezoelectric diaphragm micropump for microfluidic droplet generation with a rapid system response time. AB - Recently, we developed a convenient microfluidic droplet generation device based on vacuum-driven fluid manipulation with a piezoelectric diaphragm micropump. In the present study built on our previous work, we investigate the influence of settings applied to the piezoelectric pump, such as peak-to-peak drive voltage (Vp-p ) and wave frequency, on droplet generation characteristics. Stepwise adjustments to the drive voltage in +/-10-Vp-p increments over the range of 200 250 Vp-p during droplet creation revealed that the droplet generation rate could be reproducibly controlled at a specific drive voltage. The droplet generation rate switched within <0.5 s after the input of a new voltage. Although the droplet generation rate depended on the drive voltage, this setting had almost no influence on droplet size. The frequency over the selected range (50-60 Hz) did not markedly influence the droplet generation rate or droplet size. We show that the current fluid manipulation system can be conveniently used for both droplet generation and for rapid droplet reading, which is required in many microfluidic based applications. PMID- 30281162 TI - Requirements and Pitfalls of Dialyzer Sieving Coefficients Comparisons. AB - Sieving coefficients reported in dialyzer data sheets and instructions for use (IFUs) indicate the potential of different solutes to pass across a particular membrane. Despite being measured in vitro, sieving coefficient data are often used as a predictor of the clinical performance of dialyzers. Although standards for the measurement of sieving coefficients exist, the stated methodologies do not offer sufficient guidance to ensure comparability of test results between different dialyzers. The aim of this work was to investigate the relationship between sieving coefficients and published clinical performance indicators for two solutes, albumin loss and beta-2 microglobulin (beta2 M) reduction ratio (RR), and to assess the impact of different in vitro test parameters on sieving coefficient values for albumin, beta2 M, and myoglobin. Clinical albumin loss and beta2 M RR for commercially available dialyzers used in hemodialysis (HD) and post-dilution hemodiafiltration (HDF) were extracted from the literature and plotted against sieving coefficients reported in data sheets and IFUs. Albumin, beta2 M, and myoglobin sieving coefficients of a selection of dialyzers were measured per the ISO 8637 standard. The impact of in vitro testing conditions was assessed by changing blood flow rate, ultrafiltration (UF) rate, sampling time, and origin of test plasma. Results showed variation in albumin loss and beta2 M RR for the same sieving coefficient across different dialyzers in HD and HDF. Changes in blood flow rates, UF rates, sampling time, and test plasma (bovine vs. human) caused marked differences in sieving coefficient values for all investigated solutes. When identical testing conditions were used, sieving coefficient values for the same dialyzer were reproducible. Testing conditions have a marked impact on the measurement of sieving coefficients, and values should not be compared unless identical conditions are used. Further, variability in observed clinical data in part reflects the lack of definition of test conditions. PMID- 30281163 TI - Vacuum-Assisted Closure for Mediastinitis in Pediatric Cardiac Surgery: A Single Center Experience. AB - Vacuum-assisted closure (VAC) has been widely used to treat mediastinitis after congenital cardiac surgery, which is associated with a high risk of morbidity and mortality. The aim in this study is to review our 14 cases of mediastinitis treated with VAC therapy after congenital cardiac surgery. We retrospectively reviewed the medical records of 14 congenital heart patients with mediastinitis from January 2012 to March 2017. Patients with fever, wound discharge, sternal dehiscence, a positive wound culture or abscess diagnosed with computed tomography are accepted as mediastinitis. A VAC was applied to all our patients without irrigation or dressing the wound because of sterility concerns. The vacuuming of the wound was either 50 mm Hg or 75 mm Hg according to the sternal intactness. We gradually decreased the pressures and changed the VAC systems once every three days, after wound healing was seen and a negative culture was obtained and VAC was terminated. There were 14 patients (8 male and 6 female) with mediastinitis and all of them were treated using VAC. The mean age of the patients was 6.96 months (ranging from 0.5-26 months). The mean weight was 5.16 kg (2.8-12 kg). Three patients needed extracorporeal membrane oxygenation after the surgery. Mean onset of mediastinitis was 25.3 days. The wound cultures showed methicillin resistant coagulase negative streptococcus and methicillin-sensitive staphylococcus aureus in most cases. Acinetobacter, serratia, pseudomonas, and klebsiella were the other bacterial species seen in cultures. Two patients had mediastinitis symptoms, but their cultures were negative. VAC systems were changed 3.85 times on average. Mean duration of hospital stay was 49.9 days (21 104 days). One patient needed a muscle flap to close the thoracic cavity after mediastinitis. Two patients did not survive. Mediastinitis is a serious postoperative condition in pediatric cardiac surgery patients. Classical wound dressing and irrigation methods are not suitable in mediastinitis for the pediatric age group. Therefore, VAC therapy can be an effective way to successfully treat the situation. PMID- 30281161 TI - Daily Drinking Is Associated with Increased Mortality. AB - BACKGROUND: There is evidence that low-level alcohol use, drinking 1 to 2 drinks on occasion, is protective for cardiovascular disease, but increases the risk of cancer. Synthesizing the overall impact of low-level alcohol use on health is therefore complex. The objective of this paper was to examine the association between frequency of low-level drinking and mortality. METHODS: Two data sets with self-reported alcohol use and mortality follow-up were analyzed: 340,668 individuals from the National Health Interview Survey (NHIS) and 93,653 individuals from the Veterans Health Administration (VA) outpatient medical records. Survival analyses were conducted to evaluate the association between low level drinking frequency and mortality. RESULTS: The minimum risk drinking frequency among those who drink 1 to 2 drinks per occasion was found to be 3.2 times weekly in the NHIS data, based on a continuous measure of drinking frequency, and 2 to 3 times weekly in the VA data. Relative to these individuals with minimum risk, individuals who drink 7 times weekly had an adjusted hazard ratio (HR) of all-cause mortality of 1.23 (p < 0.0001) in the NHIS data, and individuals who drink 4 to 7 times weekly in the VA data also had an adjusted HR of 1.23 (p = 0.01). Secondary analyses in the NHIS data showed that the minimum risk was drinking 4 times weekly for cardiovascular mortality, and drinking monthly or less for cancer mortality. The associations were consistent in stratified analyses of men, women, and never smokers. CONCLUSIONS: The minimum risk of low-level drinking frequency for all-cause mortality appears to be approximately 3 occasions weekly. The robustness of this finding is highlighted in 2 distinctly different data sets: a large epidemiological data set and a data set of veterans sampled from an outpatient clinic. Daily drinking, even at low levels, is detrimental to one's health. PMID- 30281164 TI - To accept or not to accept: Level of moral concern impacts on tolerance of Muslim minority practices. AB - Living with diversity requires that we sometimes accept outgroup practices that we personally disapprove of (i.e., tolerance). Using an experimental design, we examined Dutch majority group members' tolerance of controversial practices with varying degrees of moral concern, performed by a culturally dissimilar (Muslims) or similar (orthodox Protestant) minority group. Furthermore, we examined whether arguments in favour or against (or a combination of both) the specific practice impacted tolerance. Results indicated that participants expressed less tolerance for provocative practices when it was associated with Muslims than orthodox Protestants, but not when such practices elicit high degrees of moral concern. This indicates that opposition towards specific practices is not just a question of dislike of Muslims, but can involve disapproval of specific practices. Argument framing did not have a consistent effect on the level of tolerance for the practices. PMID- 30281165 TI - Design and monitoring of survival trials in complex scenarios. AB - This paper proposes an approach to design and monitor survival trials accounting for complex scenarios such as delayed treatment effect, treatment dilution, and treatment crossover. These scenarios often lead to non-proportional hazards, making study design and monitoring more difficult. We demonstrate that, with event times following piecewise exponential distributions, the log-rank statistic as well as its variance-covariance structure can be easily computed, which greatly simplifies study design and monitoring. As the number of pieces in the exponential distributions can be arbitrary, this approach can handle a wide range of scenarios. Three hypothetical examples are used to demonstrate its potential use.

PMID- 30281167 TI - Psychological impact of different primary treatments for prostate cancer: A critical analysis. AB - Limited attention has been given to the psychological impact of primary treatments in patients with prostate cancer. Aim of our analysis was to critically analyse the current evidence on the psychological impact of different primary treatments (surgery, radiotherapy and active surveillance), in patients with prostate cancer, using validated questionnaires. We searched in the MEDLINE and Cochrane library database from the literature of the past 15 years (primary fields: prostate neoplasm, AND radical prostatectomy or radiotherapy or active surveillance AND psychological distress or anxiety or depression; secondary fields: urinary, sexual, bowel modifications, non-randomised and randomised trials). Overall eighteen original and review articles were included and critically evaluated. Either radical prostatectomy or active surveillance and radiotherapy are well-tolerated in terms of definite anxiety and depression during the post-treatment follow-up. A mutual influence between functional and psychological modifications induced by treatments has been demonstrated. Urinary symptoms related to incontinence more than sexual and bowel dysfunction are able to induce psychological distress worsening. In conclusion, patients and their clinicians might wish to know how functional and psychological aspects may differently be influenced by treatment choice. PMID- 30281168 TI - Integration of anatomical and radiological analysis suggests more segments in the human kidney. AB - An increasing number of observations have called the general scheme of five renal segments into question: anatomists, radiologists, and surgeons have reported discrepancies between Graves's scheme and morphological observations. The aims of the present study are: (1) to assess the correspondence between a virtual and a real vascular cast of the kidney; (2) to analyze the arterial anatomy with reference to the renal segments. Fifteen kidneys were injected with acrylic resins to obtain vascular casts, which were also analyzed by computed tomography. A mean of 6.3 (range 4-8) avascular fissures was found, indicating a mean of 7.3 segments (range 5-9). In the superior and middle territories there was a single segment in 4 (26.7%) and 8 (53.3%) cases, respectively, and there were two segments in 11 (73.3%) and in 7 (46.7%) cases, respectively. In the inferior territory there was a single segment in two cases (13.3%), two segments in nine (60%), and three segments in four (26.7%). A mean segmental volume of 550.5 mm3 was calculated; the posterior (1,030.1 mm3 , 28.9%) and inferior (450.3 mm3 , 24.2%) segments were the largest. More third order branches were identified in the inferior segments than in the other segments (three branches of the inferior segmental artery in 26.6%). According to these data the inferior segment occupies the inferior pole, extending both anteriorly and posteriorly. In conclusion, the high correspondence between a virtual and a real vascular cast permits more segments to be identified than those described by Graves, and the volume of each segment can be calculated.

AB - Quinones play vital roles as electron carriers in fundamental biological processes; therefore, the ability to accurately predict their electron affinities is crucial for understanding their properties and function. The increasing availability of cost-effective implementations of correlated wave function methods for both closed-shell and open-shell systems offers an alternative to density functional theory approaches that have traditionally dominated the field despite their shortcomings. Here, we define a benchmark set of quinones with experimentally available electron affinities and evaluate a range of electronic structure methods, setting a target accuracy of 0.1 eV. Among wave function methods, we test various implementations of coupled cluster (CC) theory, including local pair natural orbital (LPNO) approaches to canonical and parameterized CCSD, the domain-based DLPNO approximation, and the equations-of motion approach for electron affinities, EA-EOM-CCSD. In addition, several variants of canonical, spin-component-scaled, orbital-optimized, and explicitly correlated (F12) Moller-Plesset perturbation theory are benchmarked. Achieving systematically the target level of accuracy is challenging and a composite scheme that combines canonical CCSD(T) with large basis set LPNO-based extrapolation of correlation energy proves to be the most accurate approach. Methods that offer comparable performance are the parameterized LPNO-pCCSD, the DLPNO-CCSD(T0 ), and the orbital optimized OO-SCS-MP2. Among DFT methods, viable practical alternatives are only the M06 and the double hybrids, but the latter should be employed with caution because of significant basis set sensitivity. A highly accurate yet cost-effective DLPNO-based coupled cluster approach is used to investigate the methoxy conformation effect on the electron affinities of ubiquinones found in photosynthetic bacterial reaction centers.

PMID- 30281170 TI - Effects of maturation and size on population pharmacokinetics of pentoxifylline and its metabolites in very preterm infants with suspected late-onset sepsis or necrotizing enterocolitis: a pilot study incorporating clinical outcomes. AB - AIMS: Infection-induced inflammation is associated with adverse long-term outcomes in preterm infants. Pentoxifylline (PTX) is a candidate for adjunct immunomodulatory therapy in preterm infants with late-onset sepsis (LOS) and necrotizing enterocolitis (NEC), but pharmacokinetic data in this population are extremely limited. This study aims to characterize the pharmacokinetic properties of intravenous PTX and its metabolites in preterm infants. METHOD: An open label pilot clinical study of intravenous PTX as an adjunct therapy in preterm infants (gestation <32 weeks) with suspected LOS or NEC was undertaken. PTX was infused for 12 h for two days (60 mg kg-1 per 12 h), and in infants with confirmed diagnosis of LOS or NEC, for 6 h for another 4 days (30 mg kg-1 per 6 h). Plasma concentrations of PTX and its principal metabolites from collected blood samples were measured using a validated LCMS assay. NONMEM was used to analyse the data using population pharmacokinetic modelling. RESULTS: The preterm infants (n = 26) had a median (range) gestation of 24.8 weeks (23.3-30.4) and birthweight of 689 g (370-1285). PTX was well tolerated and without treatment-limiting adverse effects. Changes in size (weight) and maturation were successfully modelled for PTX and metabolites. After allometric scaling, clearance increased with postmenstrual age, increasing by approximately 30% per week for PTX and M1 (lisofylline) and simulations of current dosing demonstrated a six-fold difference in exposure between 24 and 35 weeks postmenstrual age. CONCLUSIONS: The developed model can be used to explore dosing strategies based on size and maturation for preterm infants. PMID- 30281171 TI - Recombinant human BMP9 (RhBMP9) in comparison with rhBMP2 for ridge augmentation following tooth extraction: An experimental study in the Beagle dog. AB - OBJECTIVES: The purpose of this study was to compare the effects of rhBMP2 with rhBMP9 on ridge augmentation following healing of extraction sockets in dogs. MATERIAL AND METHODS: Five male Beagle dogs, approximately 12 months of age, were used. The mesial roots of the four maxillary premolars were endodontically treated. The distal roots were extracted, and the buccal bony walls removed. All extraction sockets were filled with deproteinized bovine bone mineral (DBBM). A collagen membrane was soaked with 4 MUg or 20 MUg of rhBMP9, 20 MUg of rhBMP2 or sterile saline and placed over the augmented sites. All animals were euthanized after 8 weeks of healing and investigated by micro-CT and histologic analysis. A one-way ANOVA with Tukey's HSD post hoc test was used to compare the differences between the four groups. RESULTS: New bone apposition in all defects was observed from the original bone. RhBMP samples showed an increase in bone formation in the buccal area and better integration of DBBM particles when compared to control sites. Both rhBMP9 defects showed higher values of bone (p = 0.024), bone marrow (p = 0.044), and total augmentation volume (p = 0.033) than the rhBMP2 (20 MUg) or control sites. Highest bone area was found in rhBMP9 defects (p = 0.895). CONCLUSIONS: Within the limitations of the present study, rhBMP9 sites demonstrated higher bone-inducing potential in combination with DBBM than rhBMP2. While rhBMP9s failed to demonstrate a clear dose-response relationship to the outcomes, future studies are necessary to evaluate the appropriate dose and carrier systems. PMID- 30281172 TI - A Self-Portrait of Michelangelo Buonarroti Hidden in a Drawing from the Ashmolean Museum. AB - The discovery was recently announced in the scientific literature of a self caricature of the great Renaissance artist and genius of human anatomy, Michelangelo Buonarroti (1475-1564), concealed in a drawing from 1525. This drawing is held in the collection of the British Museum in London, England. In it, the artist portrayed the Marchesa di Pescara, Vittoria Colonna (1490-1547). The present article considers evidence that Michelangelo may have depicted himself in another portrait of Vittoria Colonna, dated to approximately 1522, which is currently in the collection of the Ashmolean Museum in Oxford, England. This concealed silhouetted figure displays physical features strikingly similar to those depicted in portraits of Michelangelo by his contemporaries, and in the description of the artist by Michelangelo's biographer, Giorgio Vasari (1511 1574): the large body, the shape of the face, the beard and the flattened nose. In this context, the present article could serve to facilitate analyses of the physical form and even of the state of health (from 1522) of one of the foremost anatomists of the Renaissance. Clin.

AB - Activation of the NACHT, LRR and PYD domains-containing protein 3 (NLRP3) inflammasome by Propionibacterium acnes (P. acnes) is critical for inducing inflammation and aggravating the development of acne lesions. We searched for available small-molecule inhibitors of the NLRP3 inflammasome that could be topically administered for the treatment of acne. We found that licochalcone A, a chalconoid isolated from the root of Glycyrrhiza inflate, was an effective inhibitor for P. acnes-induced NLRP3 inflammasome activation. Licochalcone A blocked P. acnes-induced production of caspase-1(p10) and IL-1beta in primary mouse macrophages and human SZ95 sebocytes, indicating the suppression of NLRP3 inflammasome. Licochalcone A suppressed P. acnes-induced ASC speck formation and mitochondrial reactive oxygen species. Topical application of licochalcone A to mouse ear skin attenuated P. acnes-induced skin inflammation as shown by histological assessment, ear thickness measurement, and inflammatory gene expression. Licochalcone A reduced caspase-1 activity and IL-1beta production in mouse ear injected with P. acnes. This study demonstrated that licochalcone A is effective in the control of P. acnes-induced skin inflammation as an efficient inhibitor for NLRP3 inflammasome. Our study provides a new paradigm for the development of anti-acne therapy via targeting NLRP3 inflammasome. PMID- 30281175 TI - A systematic review on the neuroprotective perspectives of beta-caryophyllene. AB - Beta (beta)-caryophyllene (BCAR) is a major sesquiterpene of various plant essential oils reported for several important pharmacological activities, including antioxidant, anti-inflammatory, anticancer, cardioprotective, hepatoprotective, gastroprotective, nephroprotective, antimicrobial, and immune modulatory activity. Recent studies suggest that it also possesses neuroprotective effect. This study reviews published reports pertaining to the neuropharmacological activities of BCAR. Databases such as PubMed, Scopus, MedLine Plus, and Google Scholar with keywords "beta (beta)-caryophyllene" and other neurological keywords were searched. Data were extracted by referring to articles with information about the dose or concentration/route of administration, test system, results and discussion, and proposed mechanism of action. A total of 545 research articles were recorded, and 41 experimental studies were included in this review, after application of exclusion criterion. Search results suggest that BCAR exhibits a protective role in a number of nervous system-related disorders including pain, anxiety, spasm, convulsion, depression, alcoholism, and Alzheimer's disease. Additionally, BCAR has local anesthetic-like activity, which could protect the nervous system from oxidative stress and inflammation and can act as an immunomodulatory agent. Most neurological activities of this natural product have been linked with the cannabinoid receptors (CBRs), especially the CB2R. This review suggests a possible application of BCAR as a neuroprotective agent. PMID- 30281176 TI - Flavonoid-rich fraction of Bauhinia forficata Link leaves prevents the intestinal toxic effects of irinotecan chemotherapy in IEC-6 cells and in mice. AB - This study evaluated the effects of flavonoid-rich fraction from Bauhinia forficata leaves (FRF-BF), against intestinal toxicity induced by irinotecan. The leaves of this plant are used like tea in Brazilian folk medicine, and it is rich in flavonoids, mainly kaempferitrin. First, the chemopreventive effects of FRF-BF and kaempferitrin were evaluated in intestinal cells (IEC-6 cells) exposed to irinotecan. Next, the effects were evaluated against irinotecan-induced mucositis in mice. Lastly, melanoma was induced in C57BL/6 mice to evaluate FRF-BF interference on irinotecan antitumor activity. The results showed that FRF-BF and kaempferitrin exert no cytotoxic effects in IEC-6 cells and confirmed that pretreatment with FRF-BF and kaempferitrin displays chemoprotective effects against cytotoxicity induced by irinotecan. Interestingly, the FRF-BF (100 mg/kg, p.o) reduced the intestinal motility in mice and attenuated parameters linked to irinotecan-induced intestinal mucositis, including diarrhea, histological damage, depletion of duodenal GSH, amount of TNF-alpha, and MPO activity in the small intestine. Also, FRF-BF does not interfere in the antitumor activity of irinotecan and exerted antitumoral activity in murine melanoma. In conclusion, FRF-BF (100 mg/kg, p.o) presents promising pharmacological potential to prevent and attenuate the severity of intestinal mucositis during chemotherapy treatment, related to the presence of kaempferitrin.

AB - Despite a history of purslane usage as a herbal treatment for dyslipidemia and hyperglycemia management, existing evidence from clinical trials is controversial. The aim for the current study was to evaluate the efficacy of purslane supplementation on lipid parameters and glycemic status in adult populations. A systematic review was conducted in PubMed, Scopus, ISI Web of Science, and Google Scholar up to January 15, 2018, searching for randomized controlled trials that assessed the impact of purslane on fasting blood glucose (FBG), triglycerides, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). Based on the detected heterogeneity between studies, a random- or fixed-effect model was applied in the meta-analysis. The findings from six randomized controlled trials, comprising 352 participants, indicated that purslane can reduce FBG (-4.54 mg/dl, 95% CI [-7.54, -1.53]; I2 = 0.53%) and triglycerides (-19.16 mg/dl, 95% CI [-38.17, -0.15]; I2 = 0%) levels. Changes in TC, LDL-C, and HDL-C concentrations did not reach a statistically significant level. Subgroup analysis showed a favorable effects of purslane on FBG, triglycerides, TC, and LDL-C in a subset of studies in which purslane was administered >1.5 g/day. Categorization based on gender showed that purslane was more effective in improving FBG, TC and LDL-C in females compared with males. This systematic review and meta-analysis suggested that the purslane might be effective on the improvement of blood lipid and glucose levels. Further robust studies with sufficient durations and dosages of supplementation are needed to confirm these results. PMID- 30281178 TI - Factors associated with adherence to antimicrobial stewardship after-hours. AB - OBJECTIVES: Assess restricted antimicrobials acquired after standard working hours for adherence to antimicrobial stewardship (AMS) and identify factors associated with increased likelihood of adherence at the time of acquisition, and the next standard working day. METHODS: All documented antimicrobials acquired from a paediatric hospital after-hours drug room from 1 July 2014 to 30 June 2015 were reconciled with records of AMS approval, and documented AMS review in the medical record. KEY FINDINGS: Of the 758 antimicrobial acquisitions from the after-hours drug room, 62.3% were restricted. Only 29% were AMS adherent at the time of acquisition, 15% took place despite documented request for approval by a pharmacist. Antimicrobials for respiratory patients (OR 3.10, 95% CI 1.68-5.5) and antifungals (2.48, 95% CI 1.43-4.30) were more likely to be AMS adherent. Half of the acquisitions that required review the next standard working day were adherent to AMS (51.8%, 129/249). Weekday acquisitions (2.10, 95% CI 1.20-3.69) and those for patients in paediatric intensive care (2.26, 95% CI 1.07-4.79) were associated with AMS adherence. Interactions with pharmacists prior to acquisition did not change the likelihood of AMS adherence the next standard working day. Access to restricted antimicrobial held as routine ward stock did not change the likelihood of AMS adherence at the time of acquisition, or the next standard working day. CONCLUSION: Restricted antimicrobials acquired after-hours are not routinely AMS adherent at the time of acquisition or the next standard working day, limiting opportunities for AMS involvement. PMID- 30281179 TI - Barriers to medication adherence in patients prescribed medicines for the prevention of cardiovascular disease: a conceptual framework. AB - OBJECTIVES: To identify barriers to medication adherence in patients prescribed medicines for the prevention of cardiovascular disease and map these to the Theoretical Domains Framework (TDF), to produce a conceptual framework for developing a questionnaire-based medication adherence tool. METHODS: A scoping review of barriers to medication adherence in long-term conditions was conducted to generate an initial pool of barriers. After preliminary mapping to the TDF, these barriers were presented to two focus groups of patients prescribed medicines for the prevention of cardiovascular disease (n = 14) to stimulate discussion. The group discussions enabled the patients' interpretations of the adherence barriers to be determined, provided validity from the patient perspective and identified additional barriers unrepresented in the scoping review. KEY FINDINGS: The preliminary pool of adherence barriers was identified from 47 studies across a range of long-term conditions. The majority of TDF domains were represented by these literature-identified barriers except 'social/professional role and identity' and 'behavioural regulation'. Barrier mapping was largely endorsed by focus group participants, who also contributed additional barriers, including those relating to not having a 'system' in place for managing their medicines and the negative emotions evoked by medicine taking. CONCLUSION: The TDF enabled full exploration of adherence barriers including those relating to emotions which have received limited attention in the literature. This work has provided a conceptual framework for developing a questionnaire to identify an individual's adherence barriers which may then be coupled with appropriate behaviour change techniques to deliver a theory-based intervention tailored for individual need. PMID- 30281180 TI - A randomized controlled trial of oral chloral hydrate vs intranasal dexmedetomidine plus buccal midazolam for auditory brainstem response testing in children. AB - BACKGROUND: Moderate to deep sedation is required for an auditory brainstem response test when high-intensity stimulation is used. Chloral hydrate is the most commonly used sedative, whereas intranasal dexmedetomidine is increasingly used in pediatric non-painful procedural sedations. OBJECTIVE: The aim of this study was to compare the sedation success rate after oral chloral hydrate at 50 mg kg-1 and intranasal dexmedetomidine at 3 MUg kg-1 plus buccal midazolam at 0.1 mg kg-1 for an auditory brainstem response test. METHODS: Children who required an auditory brainstem response test were recruited and randomly assigned to receive oral chloral hydrate at 50 mg kg-1 and intranasal placebo, or intranasal dexmedetomidine at 3 MUg kg-1 with buccal midazolam 0.1 mg kg-1 . The primary outcome was the rate of successful sedation for auditory brainstem response tests. RESULTS: Fifty-seven out of 82 (69.5%) were successfully sedated after chloral hydrate, while 70 out of 78 (89.7%) children were successfully sedated with dexmedetomidine plus midazolam combination, with the odd ratio (95% CI) for successful sedation between dexmedetomidine plus midazolam combination and chloral hydrate estimated to be 3.84 (1.61-9.16), P = 0.002. Dexmedetomidine plus midazolam was associated with quicker onset with median onset time 15 (IQR 11.0 19.8) for dexmedetomidine plus midazolam and 20 (IQR 15.0-27.0) for chloral hydrate respectively, with difference between median (95% CI) of 5 [3-8], P < 0.0001). The behavior observed during drug administration of intranasal dexmedetomidine and buccal midazolam was better that of the children who had oral chloral hydrate. No children required oxygen therapy or medical intervention for hemodynamic disturbances in this study and the incidence of hypotension and bradycardia was similar. CONCLUSION: Intranasal dexmedetomidine plus buccal midazolam was associated with higher sedation success with deeper level of sedation, with similar discharge time and adverse event rate when compared to chloral hydrate. PMID- 30281181 TI - Anesthetic management of thoracoscopic resection of lung lesions in small children. AB - BACKGROUND: Video-assisted thoracoscopic surgery has dramatically increased over the last decade because of both medical and cosmetic benefits. Anesthesia for video-assisted thoracoscopic surgery in small children is more challenging compared to adults due to the considerable problems posed by small airway dimensions and ventilation. The optimal technique for one-lung ventilation has yet to be established and the use of remifentanil infusion in this setting is not well described. AIMS: This study investigated the use of extraluminal bronchial blocker placement for one-lung ventilation and the effect of infusion of remifentanil in infants and small children undergoing video-assisted thoracoscopic surgery. METHODS: We retrospectively reviewed the technique of one lung ventilation and the hemodynamic effects of remifentanil infusion in 31 small children during elective video-assisted thoracoscopic surgery for congenital lung lesions under anesthesia with sevoflurane or isoflurane, oxygen, and air. Patients' heart rate, blood pressure, and endtidal carbon dioxide at baseline (after induction of anesthesia), immediately after one-lung ventilation, during carbon dioxide insufflation, and at the end of one-lung ventilation were extracted from the database and analyzed. The use of vasopressors or dexmedetomidine was also recorded and analyzed. RESULTS: Extraluminal placement of a bronchial blocker alongside the tracheal tube was successfully performed in 90.3% of cases (28 patients) without any serious complications or arterial oxygen desaturation. There was no significant rise in blood pressure or heart rate even with the rise of endtidal carbon dioxide concentration during video-assisted thoracoscopic surgery. In 58% of patients (18 patients), phenylephrine was administered to maintain the blood pressure within 20% of the baseline value. There was no significant change in the heart rate of all patients at each time point. CONCLUSION: One-lung ventilation with an extraluminal parallel blocker was used effectively in this series of young children undergoing thoracoscopic excision of congenital pulmonary lesions. Remifentanil infusion attenuated surgical stress effectively in infants and small children undergoing video assisted thoracoscopic surgery. PMID- 30281182 TI - Determination of the minimal alveolar concentration of sevoflurane associated with isoelectric electroencephalogram in children: A prospective, randomized, double-blind study. AB - OBJECTIVE: We investigated the minimal alveolar concentration (MAC) of sevoflurane associated with the occurrence of isoelectric electroencephalogram in 50% of children under steady-state conditions (MAC IE). The MAC IE was determined in 100% oxygen and with the addition of 50% nitrous oxide or after the injection of fentanyl. METHODS: Seventy-two children (ASA I or II, age 3-8 years) undergoing elective surgery were allocated to one of three groups: in 100% oxygen (group O2 ), in 50% oxygen and 50% nitrous oxide (group N2 O), or in 100% oxygen with a bolus of 3 MUg/kg fentanyl (group FENTANYL). The state of isoelectric EEG was considered as significant when a burst suppression ratio of 100% lasted for >1 minute. The MAC IE was determined by the Dixon's up-and-down method after a 15 minute period with a stable endtidal concentration of sevoflurane. The concentration of sevoflurane was determined by the electroencephalogram of the previous patient: increase of 0.2% if isoelectric EEG were absent or decrease of 0.2% if isoelectric EEG were present. RESULTS: The MAC IE in group O2 (MAC IEO 2 ) was 5.30 (5.12-5.48)% (median [95% CI]). The MAC IE in group N2 O (MAC IEN 2O ) was 5.83 (5.67-5.99)%. The MAC IE in group FENTANYL (MAC IEFENTANYL ) was 5.37 (5.21-5.53)%, which was close to MAC IEO 2 . CONCLUSION: The MAC IE of sevoflurane calculated in 100% O2 was 5.30% in children. Addition of 50% N2 O modestly increased MAC IE of sevoflurane, while 3 MUg/kg fentanyl had no effect on MAC IE of sevoflurane. PMID- 30281183 TI - Clinical Comparative Evaluation of Nd:YAG Laser and a New Varnish Containing Casein Phosphopeptides-Amorphous Calcium Phosphate for the Treatment of Dentin Hypersensitivity: A Prospective Study. AB - PURPOSE: The aim of this study was to compare the effect of Nd:YAG laser to that of a new varnish: MI Varnish with RECALDENT (GC), for the treatment of dentin hypersensitivity, with a follow-up of 6 months. Dentinal hypersensitivity was evaluated using a new thermal test never before used on dental tissue. MATERIALS AND METHODS: A split-mouth design was used where teeth on one side received the same type of treatment. Twelve patients suffering from dentin hypersensitivity were chosen. Fifty-four teeth were divided into 27 pairs. Twenty-seven teeth received the Nd:YAG laser treatment, and the 27 contralateral teeth received MI Varnish application. Five parameters were measured, and the measurements were taken before treatment at baseline (T0), after 1 week (T1), 1 month (T2), 3 months (T3), and 6 months (T4) of the application. Air stimulation to obtain the Schiff air score, the score of discomfort according to the visual analog scale (VAS), the tactile score, and the thermal test that determines the minimum cold stimulating temperature and the maximum heat-stimulating temperature were all used to assess sensitivity. Statistical analyses of the data were performed, and the significance level was set at p <= 0.05. Exact Fisher tests and Chi-Square tests were conducted to compare percentages. RESULTS: There was a clear decrease in dentin hypersensitivity for both treatments (Nd:YAG laser and MI Varnish) especially between baseline and 1 week, with maintenance of this state through the 6-month follow-up period. The difference between the two treatments was not significant, comparing, over time, the Schiff air score, the thermal test, and the VAS; however, the tactile score was significantly improved 6 months after the application of MI Varnish compared to the laser (p = 0.05). CONCLUSION: There was no significant difference between the two treatments, Nd:YAG laser and MI Varnish. Both treatments were effective and reduced dentin hypersensitivity immediately after treatment up to 6 months. PMID- 30281184 TI - Physical activity and sedentary behaviour in a residential aged care facility. AB - OBJECTIVE: To evaluate sedentary behaviour and physical activity levels in independently mobile older adults with and without dementia living in residential aged care. METHODS: Sedentary behaviour and physical activity were measured in 37 residents of an aged care facility using an accelerometer worn during waking hours for five days. RESULTS: Participants with valid accelerometer data (n = 28) spent 85% of the time sedentary, and 12% in low-intensity, 2% in light-intensity and 1% in moderate-to-vigorous-intensity physical activity. Over half of sedentary time was accumulated in bouts of greater than 30 minutes. Physical activity at any level of intensity was performed in bouts of less than 10 minutes. CONCLUSION: Residents were highly sedentary and inactive. In particular, the short duration of each bout of activity amongst lengthy periods of sedentary behaviour was a substantial finding. The study suggests the need to develop innovative ways of breaking up sedentary behaviour in residential aged care. PMID- 30281185 TI - Diagnosis and perioperative management in pediatric sleep-disordered breathing. AB - Sleep-disordered breathing has a prevalence of 12% in the pediatric population. It represents a spectrum of disorders encompassing abnormalities of the upper airway that lead to sleep disruption, including primary snoring, obstructive sleep apnea, central sleep apnea, and sleep-related hypoventilation. Sleep disordered breathing is the most common indication for adenotonsillectomy, one of the most common procedures performed in children. In recent years, the American Academy of Otolaryngology-Head and Neck Surgery, American Academy of Pediatrics, and the American Society of Anesthesiologists have crafted guidelines to help safely manage children with sleep-disordered breathing. Each organization recommends in-laboratory polysomnography for definitive diagnosis of obstructive sleep apnea in certain cases. However, because this test is both costly and inconvenient, there has been significant interest in alternative methods for diagnosing clinically significant sleep-disordered breathing. Accurate diagnosis is critical because sleep-disordered breathing confers certain perioperative risks and increased mortality in some instances. Recent studies have elucidated the danger of anesthesia and opioids in worsening obstructive sleep apnea, and recommendations for alternative analgesia are being created. In addition, determining the most appropriate level and duration of monitoring in the postoperative period is actively being evaluated. This article presents an overview of the recent literature on the perioperative care of pediatric patients with sleep-disordered breathing. It highlights innovative modalities and limitations in diagnosing obstructive sleep apnea, the importance of a tailored anesthetic/analgesic approach to children with obstructive sleep apnea, and the need for postoperative monitoring. It also brings to focus that further studies on the perioperative care of these children are necessary. PMID- 30281186 TI - Trends in adverse drug reactions related hospitalisations over 13 years in New South Wales, Australia. AB - AIMS: To examine trends in adverse drug reactions (ADR)-related hospitalisations in New South Wales (NSW). METHODS: Data were extracted from the Admitted Patient Data Collection (APDC), a census of hospital separations in NSW. We estimated age adjusted rates of ADE-related hospitalisation between 1st July 2001 and 30th June 2014, and rates by patient characteristics, main therapeutic medication groups, and clinical condition groups that warranted the hospitalisation. We used the percent change annualised estimator to evaluate rates over time. RESULTS: A total of 315,274 NSW residents admitted for urgent care of ADRs were identified. The age-adjusted rates of ADR-related hospitalisations nearly doubled and increased by 5.8% (95%CI: 5.0-6.6%) per annum, with in-hospital death rate increase of 2.4% (1.6-3.3%). Agranulocytosis (2.7%), nausea and vomiting (2.4%), and heart failure (2.4%) were the most common conditions that lead to ADR-related hospitalisations over 13 years, with acute renal failure (1.4%) recently emerging as the leading adverse condition. Participants aged between 65 and 84 years accounted for nearly half of ADR-hospitalisations (45.6%), with age-adjusted rate increasing from 103.9 in 2001-02 to 189.0 per 100,000 NSW residents in 2013-14. Anticoagulants (13.5%) were the most common medications contributing to ADR-related hospitalisation, followed by opioid analgesics (9.6%). CONCLUSIONS: ADR-related hospitalisation remains a population health burden with significant increase over time. The findings call for continuing efforts to prevent ADRs, especially among high risk populations such as older people. This article is protected by copyright. All rights reserved. PMID- 30281187 TI - Expectations of care within marriage for older couples. AB - OBJECTIVES: This study explores the intersection of marriage and caregiving amongst older spousal caregivers in regional Australia. Specifically, we address the research question: 'How do expectations of informal care impact spousal caregivers in later life?' METHODS: These comprise interpretive qualitative in depth interviews in order to understand the lived experience of caregiving within the context of long-term marriage. RESULTS: Findings highlight the complexity and diversity of marital relationships as the context of informal care. Individual and social obligations were evident in key themes, demonstrating how spouses automatically assume and continue in caregiver roles in later life. CONCLUSION: Caregiving is an expectation of couples in long-term marriages, regardless of the relationship quality and willingness to care. Normative expectations also impact decision-making around future care planning and transitions away from home-based care. These are important considerations for both policy and practice with older adults and their caregivers. PMID- 30281188 TI - Newly proposed electrocardiographic criteria for the diagnosis of left ventricular hypertrophy in a Chinese population. AB - BACKGROUND: The electrocardiographic criteria currently available for the diagnosis of left ventricular hypertrophy (LVH) are low in sensitivity. Thus, we compared the diagnostic performance of newly proposed electrocardiographic criteria to the existing criteria in a Chinese population. METHODS: A total of 235 consecutive hypertensive patients, hospitalized in our department between May 2017 and April 2018, were included. They were divided into two groups based on the gold standard echocardiogram: those with (n = 116) and without LVH (n = 119). The newly proposed ECG criteria were calculated by summating the amplitude of the deepest S wave (SD ) in any single lead and the S-wave amplitude of lead V4 (SV4 ). The area under the curve was calculated and compared against the sex-specific Cornell limb lead and Sokolow-Lyon criteria. RESULTS: ECG analysis of the cohort showed that the newly proposed criteria had the highest sensitivity in diagnosing LVH (male: 65.5%; female: 81%), followed by the Cornell limb lead criteria (male: 55.2%; female: 56.9%). The specificities of both sets of criteria were higher than 70%, with no significant differences between them. Receiver operator curve analysis showed an optimal cutoff of >=2.1 mV for females (AUC: 0.832; 95% CI: 0.757-0.906) and >=2.6 mV for males (AUC: 0.772; 95% CI: 0.687-0.856). CONCLUSION: The newly proposed SD + SV4 criteria provide an improved sensitivity for the ECG diagnosis of LVH compared to existing criteria, but its routine use will require further validation in larger populations. PMID- 30281189 TI - Predicting tubal factor infertility by using markers of humoral and cell-mediated immune response against Chlamydia trachomatis. AB - PROBLEM: The accuracy of Chlamydia trachomatis antibody test in predicting tubal factor infertility (TFI) is limited, and more accurate methods are needed. Cell mediated immune response (CMI) is crucial in the resolution of pathogen, but it may play an important role in the pathogenesis of C trachomatis-associated tubal damage. We studied whether combining the markers of C trachomatis-induced CMI to humoral immune response improves the accuracy of serology in TFI prediction. METHOD OF STUDY: Our prospective study consists of 258 subfertile women, of whom 22 (8.5%) had TFI. Women with other causes for subfertility served as a reference group. Serum C trachomatis major outer membrane protein (MOMP) and chlamydial heat-shock protein 60 (cHSP60) IgG antibodies were measured by ELISA. CMI was studied by lymphocyte proliferation assay in vitro. RESULTS: Serological markers were more prevalent in women with TFI than in other subfertile women (40.9% vs 12.3% for MOMP IgG and 27.3% vs 10.2% for cHSP60 IgG). The best test combination for TFI was C. trachomatis MOMP and cHSP60 antibody with an accuracy of 90.3%, sensitivity of 22.7% and specificity of 96.6%. Positive post-test probability of this combination was 54.2%, and negative post-test probability was 12.4%. Adding of the markers of CMI did not significantly improve the accuracy of serology in TFI prediction. CONCLUSION: The accuracy of TFI prediction increases when the combination of C trachomatis MOMP and cHSP60 antibody tests is used. C trachomatis-induced CMI was common in our study population, but the markers of CMI did not predict TFI. PMID- 30281191 TI - Shark Fin Titanium Hollow Bulb Obturator: A Treatment Concept. AB - Restoring esthetics and function for patients with maxillectomy defects presents a complex challenge for the clinician. Obturator prostheses are subject to rotational forces during function, allowing movement into the defect. Gaining prosthesis support from endosseous implants can limit the amount of rotation. Xerostomia and impaired tissue healing caused by radiation therapy further complicates the treatment for such patients. Several resilient and rigid obturator design concepts are available for restoration of such defects. This clinical report describes a design concept used to treat a patient with a maxillectomy defect caused by tumor resection secondary to a squamous cell carcinoma. PMID- 30281192 TI - The use of chromium (III) complexes to enhance peptide protonation by electrospray ionization mass spectrometry. AB - The addition of trivalent chromium, Cr (III), reagents to peptide solutions can increase the intensity of doubly protonated peptides, [M + 2H]2+ , through electrospray ionization (ESI). Three model heptapeptides were studied: neutral (AAAAAAA), acidic (AAEEEAA), and basic (AAAKAAA). The neutral and acidic peptides form almost no 2+ ions in the absence of Cr (III). Twenty Cr (III) complexes were used as potential enhanced protonation reagents, including eleven complexes with non-labile ligands and nine with labile ligands. The complexes that provide the most abundant [M + 2H]2+ , the greatest [M + 2H]2+ to [M + H]+ ratio, and the cleanest mass spectra are [Cr(H2 O)6 ](NO3 )3 .3H2 O and [Cr (THF)3 ]Cl3 . Anions in Cr (III) reagents can also affect the intensity of [M + 2H]2+ and the [M + 2H]2+ to [M + H]+ ratio through cation-anion interactions. The influence of anions on the extent of peptide protonation follows the trend ClO4 - ? SO4 2- ? Br- ? Cl- ? F- ~ NO3 - . Solvent effects and complexes with varying number of water ligands were investigated to study the importance of water in enhanced protonation. Aqueous solvent systems and Cr (III) complexes that have at least one bound water ligand in solution must be used for successful increase in the intensity of [M + 2H]2+ , which indicates that water is involved in the mechanism of Cr (III)-induced enhanced protonation. The ESI source design is also important because no enhanced protonation was observed using a Z-spray source. The current results suggest that this Cr (III)-induced effect occurs during the ESI desolvation process. PMID- 30281193 TI - Successful use of "Choice Architecture" and "Nudge Theory" in a quality improvement initiative of analgesia administration after Caesarean section. AB - BACKGROUND: Regular, routine, multimodal analgesia provides better pain relief following Caesarean section than reliance on "as required" opiate dosing. This quality improvement report describes the effective use of an education programme coupled with a highlighted, preprinted medication chart, employing "Nudge Theory" principles to achieve significant improvements in the administration of analgesic medications to patients after Caesarean section operations. PROBLEM: An acute pain service audit identified a serious deficiency with delivery of regular postoperative analgesic medications to patients following Caesarean section operations. METHODS: An audit of pain medication delivery to patients following Caesarean section demonstrated that postoperative analgesia was not being administered in line with local prescribing guidelines. Two interventions were planned: Education sessions for anaesthetic recovery and ward staff. Introduction of a new preprinted and highlighted medication chart. A postintervention audit was then conducted. RESULTS: There were statistically significant improvements in all medications administered to patients following the two interventions. For analgesic medications, the rate of administration of drugs in compliance with guidelines rose from 39.6% to 89.9% (P < 0.001 using 2-sample z test). Each subgroup of medications also showed statistically significant improvements in administration compliance. CONCLUSION: A combined approach, including application of "Nudge Theory" to the administration of analgesic medication after Caesarean section, considerably improved delivery of medications prescribed for postoperative analgesia. PMID- 30281194 TI - A Janus Nickel Cobalt Phosphide Catalyst for High-Efficiency Neutral-pH Water Splitting. AB - Transition-metal phosphides have stimulated great interest as catalysts to drive the hydrogen evolution reaction (HER), but their use as bifunctional catalytic electrodes that enable efficient neutral-pH water splitting has rarely been achieved. Herein, we report the synthesis of ternary Ni0.1 Co0.9 P porous nanosheets onto conductive carbon fiber paper that can efficiently and robustly catalyze both the HER and water oxidation in 1 m phosphate buffer (PBS; pH 7) electrolyte under ambient conditions. A water electrolysis cell comprising the Ni0.1 Co0.9 P electrodes demonstrates remarkable activity and stability for the electrochemical splitting of neutral-pH water. We attribute this performance to the new ternary Ni0.1 Co0.9 P structure with porous surfaces and favorable electronic states resulting from the synergistic interplay between nickel and cobalt. Ternary metal phosphides hold promise as efficient and low-cost catalysts for neutral-pH water splitting devices. PMID- 30281195 TI - Perioperative respiratory adverse event risk assessment in children with upper respiratory tract infection: Validation of the COLDS score. AB - BACKGROUND: The decision to proceed with anesthesia and surgery has been controversial in pediatric patients with an upper respiratory tract infection. The COLDS score was proposed by Lee and August as a potential risk stratification scheme, but no validation has been performed on this scale. AIMS: The aim of this study was to evaluate the utility of the COLDS score in predicting perioperative respiratory adverse events and optimize its predictive ability. METHODS: COLDS scores, incidence of perioperative respiratory adverse events, surgical procedure type, and age were prospectively collected for 536 patients who met inclusion criteria. Area under the receiver operating characteristic curves was computed for total COLDS score and individual COLDS score categories. Multivariable regression was used create an optimized score. To quantify the decrease in risk associated with case cancelation due to illness, the other risk factors in COLDS were assessed separately from upper respiratory infection status and a risk model was created. RESULTS: The area under the receiver operating characteristic curve for the total COLDS score was 0.69, suggesting that the COLDS score has a moderate predictive ability for perioperative respiratory adverse events. When split into individual component scores, the area under the receiver operating characteristic curve ranged from 0.55 to 0.63. We also found that the area under the receiver operating characteristic curve for the scoring system was higher in younger children than for children aged 4-6 (area under receiver operating characteristic curve of 0.70-0.71 vs 0.66). The area under the receiver operating characteristic curve for the optimized scoring system was 0.71. CONCLUSION: The COLDS score has the potential to be a valuable risk assessment tool for prediction of perioperative respiratory adverse events and appears to have a better predictive value in certain subpopulations. PMID- 30281196 TI - A sluggish mid-Proterozoic biosphere and its effect on Earth's redox balance. AB - The possibility of low but nontrivial atmospheric oxygen (O2 ) levels during the mid-Proterozoic (between 1.8 and 0.8 billion years ago, Ga) has important ramifications for understanding Earth's O2 cycle, the evolution of complex life and evolving climate stability. However, the regulatory mechanisms and redox fluxes required to stabilize these O2 levels in the face of continued biological oxygen production remain uncertain. Here, we develop a biogeochemical model of the C-N-P-O2 -S cycles and use it to constrain global redox balance in the mid Proterozoic ocean-atmosphere system. By employing a Monte Carlo approach bounded by observations from the geologic record, we infer that the rate of net biospheric O2 production was 3.5-1.1+1.4 Tmol year-1 (1sigma), or ~25% of today's value, owing largely to phosphorus scarcity in the ocean interior. Pyrite burial in marine sediments would have represented a comparable or more significant O2 source than organic carbon burial, implying a potentially important role for Earth's sulphur cycle in balancing the oxygen cycle and regulating atmospheric O2 levels. Our statistical approach provides a uniquely comprehensive view of Earth system biogeochemistry and global O2 cycling during mid-Proterozoic time and implicates severe P biolimitation as the backdrop for Precambrian geochemical and biological evolution. PMID- 30281197 TI - Fear of Childbirth, Postpartum Depression, and Birth-Related Variables as Predictors of Posttraumatic Stress Disorder After Childbirth. AB - BACKGROUND: Childbirth may be a significant cause of postpartum posttraumatic stress disorder (PTSD) in women. AIMS: The objective of this study is to examine the effect of fear of childbirth, postpartum depression, and certain birth related variables on postpartum PTSD. METHODS: This study is a cross-sectional study. The study was carried out in a maternity hospital nonstress unit between December 1, 2015, and February 29, 2016. Three hundred and one pregnant women who met the criteria for inclusion in the study made up the research sample. RESULTS: Fear of childbirth and postpartum depression significantly and positively predicted the level of posttraumatic stress after childbirth (beta = 0.17, p < .01; beta = 0.68, p < .001). Fear of childbirth explains 3% of the total variance in posttraumatic stress (R2 = .03, adjusted R2 = .02, F = 7.141, p < .01), while postpartum depression explains 47% of it (R2 = .47, adjusted R2 = .46, F = 196.35, p < .001). Satisfaction with the attitudes of the medical staff during childbirth, defining the childbirth experience, and the state of experiencing postpartum problems by the mother are significant predictors of postpartum posttraumatic stress (beta = -0.21, p < .01; beta = -0.14, p < .05; beta = 0.17, p < .01). When these three variables are addressed together, they explain 14% of the total variance (R2 = .14, adjusted R2 = .13, F = 9.33, p < .001). LINKING EVIDENCE TO ACTION: Postpartum PTSD is a situation that must be carefully emphasized in terms of maternal, baby, and family health. For this reason, it is necessary to evaluate postpartum PTSD more quickly and objectively, and healthcare providers have major duties in this respect. PMID- 30281199 TI - Supplements. PMID- 30281198 TI - A hybrid planning strategy for stereotactic body radiation therapy of early stage non-small-cell lung cancer. AB - Currently dynamic conformal arcs (DCA) and volumetric modulated arc therapy (VMAT) are two popular planning techniques to treat lung stereotactic body radiation therapy (SBRT) patients. Of the two, DCA has advantages in terms of multi-leaf collimator (MLC) motion, positioning error, and delivery efficiency. However, VMAT is often the choice when critical organ sparing becomes important. We developed a hybrid strategy to incorporate DCA component into VMAT planning, results were compared with DCA and VMAT plans. Four planning techniques were retrospectively simulated for 10 lung SBRT patients: DCA, Hybrid-DCA (2/3 of the doses from DCA beams), Hybrid-VMAT (2/3 of the doses from VMAT beams) and VMAT. Plan complexity was accessed by modulation complexity score (MCS). Conformity index (CI) for the planning target volume (PTV), V20 and V5 for the lung, V30 for the chestwall, and maximum dose to all other critical organs were calculated. Plans were compared with regard to these metrics and measured agreement between the planned and delivered doses. DCA technique did not result in acceptable plan quality due to target location for five patients. Hybrid-DCA produced one unacceptable plan, and Hybrid-VMAT and VMAT produced no unacceptable plans. The CI improved with increasing VMAT usage, as did the dose sparing to critical structures. Compared to the VMAT technique, a total MU reduction of 14%, 25% and 37% were found for Hybrid-VMAT, Hybrid-DCA and DCA techniques for 54 Gy patient group, and 9%, 23% and 34% for 50 Gy patient group, suggesting improvement in delivery efficiency with increasing DCA usage. No significant variations of plan complexity were observed between Hybrid-DCA and Hybrid-VMAT (P = 0.46 from Mann Whitney U-test), but significant differences were found among DCA, Hybrid and VMAT (P < 0.05). Better agreements between the planned and delivered doses were found with more DCA contributions. By adding DCA components to VMAT planning, hybrid technique offers comparable dosimetry to full VMAT, while increasing delivery efficiency and minimizing MLC complexity. PMID- 30281200 TI - Ethnic disparities in relationships of obesity indices with telomere length in Asians with type 2 diabetes. AB - BACKGROUND: Obesity and shorter telomeres increase the risk for diabetes complications and mortality. However, the relationship between obesity and telomere length in diverse Asian populations with type 2 diabetes (T2D) is not well understood. This study examined the association of baseline and changes in obesity indices with telomere length in multiethnic Asian populations with T2D. METHODS: Leukocyte telomere length (LTL) was measured by quantitative polymerase chain reaction in the SMART2D cohort (n = 1431 at baseline, n = 1039 after 3.2 years median follow-up). Associations between obesity indices and LTL were assessed by linear regression. RESULTS: Compared with Chinese, LTL was longer in Malays (P < 0.0001) and similar in Indians. Cross-sectionally, body mass index (BMI)-adjusted (residual) visceral fat area (VFA; beta = -0.004, P = 0.006), and waist-to-hip ratio (beta = -1.95, P = 0.030) were significantly associated with LTL in Chinese but not in Malays and Indians. Changes in BMI (r = -0.080; P = 0.053) and VFA (r = -0.126; P = 0.002) were inversely correlated with changes in LTL only in Chinese. Furthermore, in Chinese, 1-SD incremental changes in BMI (beta = -0.070; P = 0.040) and VFA (beta = -0.088, P = 0.028) were significantly associated with larger telomere attrition, independent of age, sex, diabetes condition, baseline LTL, obesity, and inflammation markers. CONCLUSIONS: Three year changes in BMI and VFA were associated with telomere dynamics in Chinese but not in Malays and Indians with T2D. Reducing obesity may reduce the risk of diabetes complications associated with shorter LTL in the Chinese population. PMID- 30281201 TI - Global Profiling of PknG Interactions Using a Human Proteome Microarray Reveals Novel Connections with CypA. AB - Mycobacterium tuberculosis (Mtb) serine/threonine kinase PknG plays an important role in the Mtb-host interaction by facilitating the survival of Mtb in macrophages. However, the human proteins with which the PknG interacts, and the underlying molecular mechanisms are still largely unknown. In this study, a HuProt array is been applied to globally identify the host proteins to which PknG binds. In this way, 125 interactors are discovered, including a cyclophilin protein, CypA. This interaction between PknG and CypA is validated both in vitro and in vivo, and functional studies show that PknG significantly reduces the protein levels of CypA through phosphorylation, which consequently inhibit the inflammatory response through downregulation of NF-kappaB and ERK1/2 pathways. Phenotypically, overexpression of PknG reduces cytokine levels and promotes the survival of Mycobacterium smegmatis (Msm) in macrophages. Overall, it is expected that the PknG interactors identified in this study will serve as a useful resource for further systematic studies of the roles that PknG plays in the Mtb host interactions. PMID- 30281202 TI - Rheumatic syndromes associated with immune-checkpoint inhibitors: a single-center cohort of 61 patients. AB - OBJECTIVES: To describe the prevalence, clinical presentation, and management of rheumatic immune-related adverse effects (Rh-irAEs) from immune checkpoint inhibitor therapy. METHODS: From a database of all patients who received any immune-checkpoint inhibitor at the Mayo Clinic Rochester, Minnesota campus between January 1st, 2011 and March 1st, 2018, we retrospectively identified those with Rh-irAEs using diagnostic codes, search terms, and manual chart review. RESULTS: Of the 1,293 patients who received any checkpoint inhibitor, 43 were clinically diagnosed with Rh-irAEs. Eighteen patients with Rh-irAEs who received ICI therapy elsewhere were also analyzed. Clinical syndromes included inflammatory arthritis (IA) (n=34, prevalence 2%), myopathy (n=10), and other rheumatic syndromes (n=17). IA was most commonly polyarticular and 26 patients (76%) required glucocorticoids. Mean treatment duration was 18 weeks (SD 18 weeks). Five patients (15%) also received disease-modifying drugs and 3 patients (9%) required discontinuation of ICI therapy. Myopathy was treated with glucocorticoids in all cases for a mean duration of 15 weeks (SD 17 weeks) and lead to two deaths and permanent ICI discontinuation in 9 patients (90%). Other syndromes included connective tissue diseases, vasculitis, PMR-like syndrome, and flared pre-existing rheumatic disease. Most (71%) were treated with immunosuppression with 12% requiring ICI discontinuation. CONCLUSION: This study represents the largest cohort of Rh-irAEs to date. Most patients received long courses of immune suppression, though only a minority required ICI discontinuation. This article is protected by copyright. All rights reserved.

AB - Unlike the synthetic surfactants, mono- and diacylglycerols have the advantage to be biodegradable and non-toxic. In the present work, the hydrolysis of lipid fraction by-products of refined vegetable oils was performed by Serratia sp. W3 lipase immobilized on CaCO3 by combined adsorption and precipitation. This support was selected out of four carriers as it exhibited the finest activity support (950 U/g) and the most satisfactory behavior at use. The immobilized preparation with CaCO3 was stable and active in the whole range of pH (4 to 9) and temperature (37 to 55 degrees C), yielding a 75% degree of hydrolysis at optimal environmental conditions of pH 8.5 and temperature 55 degrees C. Thin layer chromatography, gas chromatography, and liquid chromatography methods were evaluated to determine the analytical characterization of hydrolysis products. For monoacylglycerols and diacylglycerol fractions identified in the samples, a novel approach by liquid chromatography method was employed, through a homemade linear retention index database and a dedicated software. The adopted approach allowed the use of basic instrumentation set-ups, without the need of sophisticated detectors, such as mass spectrometers. Thus, it could be an effective alternative to produce emulsifiers from cheap vegetable oils. PMID- 30281205 TI - Altered Cervical Spinal Cord Resting State Activity in Fibromyalgia. AB - OBJECTIVE: Altered afferent input and central neural modulation are thought to contribute to fibromyalgia symptoms, and these processes converge within the spinal cord. We hypothesized that, using resting state functional magnetic resonance imaging (rs-fMRI) of the cervical spinal cord, we would observe altered frequency dependent activity in fibromyalgia. METHODS: Cervical spinal cord rs fMRI was performed in fibromyalgia patients and healthy controls. We analyzed a measure of low frequency oscillatory power, the amplitude of low frequency fluctuations (ALFF), for frequencies 0.01 - 0.198 Hz and frequency sub-bands, to determine regional and frequency-specific alterations in fibromyalgia. Functional connectivity and graph metrics were also analyzed. RESULTS: As compared to controls, greater ventral and lesser dorsal Mean ALFF of the cervical spinal cord was observed in fibromyalgia (p < 0.05, uncorrected) for frequencies 0.01 - 0.198 Hz and all sub-bands. Additionally, lesser Mean ALFF within the right dorsal quadrant (p < 0.05, corrected) for frequencies 0.01 - 0.198 Hz and sub-band frequencies 0.073 - 0.198 Hz was observed in fibromyalgia. Regional Mean ALFF was not correlated with pain, however, regional lesser Mean ALFF was correlated with fatigue in patients (r = 0.763, p = 0.001). Functional connectivity and graph metrics were similar between groups. CONCLUSION: Our results indicate unbalanced activity between the ventral and dorsal cervical spinal cord in fibromyalgia. Increased ventral neural processes and decreased dorsal neural processes may reflect the presence of central sensitization and contribute to fatigue and other bodily symptoms in fibromyalgia.

A Test of Food Industry Concerns. AB - OBJECTIVE: This study aimed to test the industry claim that "high in" front-of package (FOP) labeling systems are perceived as harsh and reduce consumers' control over food choices. METHODS: Respondents aged 16 to 32 years completed a between-group experimental task in an online survey (n = 1,000). Participants viewed a beverage with one of four FOP labels (text-only, octagon, triangle, or health star rating) and rated the label on its "harshness" and whether it made them feel more or less "in control" of their healthy eating decisions. RESULTS: Across all label conditions, at least 88% of respondents indicated the symbols were "about right" or "not harsh enough." At least 93% felt the symbols made them feel "more in control" or "neither less nor more in control." Participants viewing the health star rating were more likely to rate the symbol as "not harsh enough" and less likely to state that the symbol made them feel "more in control." CONCLUSIONS: There was no evidence to support industry claims that consumers perceive "high in" FOP symbols as harsh or as restricting their control. Indeed, most participants reported that the symbols were about the right harshness, and that they increased their control, including "stop sign" FOP symbols similar to those implemented in Chile. PMID- 30281207 TI - Characteristics of Usual Physical Therapy Post-Total Knee Replacement and their Associations with Functional Outcomes. AB - OBJECTIVE: Although total knee replacement surgery (TKR) is highly prevalent and generally successful, functional outcomes post-TKR vary widely. Most patients receive some physical therapy (PT) following TKR, but PT practice is variable and associations between specific content and dosage of PT interventions and functional outcomes are unknown. Research has identified exercise interventions associated with better outcomes but studies have not assessed whether such evidence has been translated into clinical practice. We characterized the content, dosage and progression of usual post-acute PT services following TKR, and examined associations of specific details of post-acute PT with patients' 6 month functional outcomes. METHODS: Post-acute PT data were collected from patients undergoing primary unilateral TKR and participating in a clinical trial of a phone-based coaching intervention. PT records from the terminal episode of care were reviewed and utilization and exercise content data were extracted. Descriptive statistics and linear regression models characterized PT treatment factors and identified associations with 6-month outcomes. RESULTS: We analyzed 112 records from 30 PT sites. Content and dosage of specific exercises and incidence of progression varied widely. Open chain exercises were utilized more frequently than closed chain (median and interquartile range (21(4,49) vs 13(4,28.5)). Median (interquartile range) occurrence of progression of closed and open chain exercise was 0 (0,2) and 1 (0,3) respectively. Shorter timed stair climb was associated with greater total number of PT interventions and use and progression of closed chain exercises. DISCUSSION: Data suggest that evidence based interventions are under-utilized and dosage may be insufficient to obtain optimal outcomes. This article is protected by copyright. All rights reserved. PMID- 30281209 TI - A Novel Strategy to Investigate Tissue-Secreted Tumor Microenvironmental Proteins in Serum toward Development of Breast Cancer Early Diagnosis Biomarker Signature. AB - PURPOSE: The study aims to discover and identify early grade diagnosis markers in tumor microenvironment and investigates their expression in serum. EXPERIMENTAL DESIGN: 2D fluorescence difference gel electrophoresis (2D-DIGE), a gel-based proteomics platform is used for tissue profiling and identifies deregulated proteins by matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry. Western blot validation for statistically significant six different proteins is performed in an independent cohort of participant serum. RESULTS: Total 67 nonredundant tissue proteins are identified out of 230 protein spots obtained through Marker selection tool of EDA. GELS, DAPLE, IQCC, CATD, A1AT, and HS90B are selected for validation and found to be upregulated in early grade serum samples. Pathway analysis performed through PANTHER and DAVID indicates that apoptosis, CCKR, EGF, FAS, FGF, Wnt, p13 kinase, and p53 signaling pathways are expressed specifically during or early onset of grade I cancer lesions. CONCLUSIONS AND CLINICAL RELEVANCE: GELS, DAPLE, HS90B, A1AT, IQCC, and CATD may be promising potential serum biomarker signature for diagnosis of early grade breast cancer. This panel also contributes to better understanding of molecular mechanisms involved in inceptive stage of breast cancer. PMID- 30281208 TI - Mismatch in Children's Weight Assessment, Ideal Body Image, and Rapidly Increased Obesity Prevalence in China: A 10-Year, Nationwide, Longitudinal Study. AB - OBJECTIVE: This study examined secular trends in children's weight-status assessment, measured weight status, and ideal body image and their associations with subsequent changes in BMI, and it explored the differences between sociodemographic groups in China. METHODS: Longitudinal data from the China Health and Nutrition Survey of 4,605 children aged 6 to 17 collected between 2000 and 2011 were used and fitted to mixed models. RESULTS: From 2000 to 2011, overweight/obesity prevalence increased from 6.5% to 16.8%, but the percentage of children with self-perceived weight status as "fat" remained around 2.0%; 49.0% of children underestimated their weight status at baseline. Self-perceived body image of most participants was tracked during follow-up. Children who perceived themselves as being fat at baseline had a higher BMI increase over time during follow-up than those with an average body image (beta [SE] = 0.99 [0.14] kg/m2 per year, P < 0.001). Boys, young children, recent cohorts, and rural children had higher BMI increases than their counterparts. Over time, the thin-body silhouette became more desirable (8.4 percentage points higher, P < 0.001). CONCLUSIONS: Chinese children experience a large incongruence between their weight-status assessment, ideal body image, and actual weight status. Health promotion programs should examine their role in assisting children in developing a healthy body image and gaining greater self-motivation toward promoting a healthy lifestyle. PMID- 30281210 TI - Maternal and Postnatal Supplementation of Fish Oil Improves Metabolic Health of Mouse Male Offspring. AB - OBJECTIVE: Over half of American women of childbearing age have either obesity or overweight. Hence, maternal programming through diet is critical for prevention of diseases in the offspring. Clinical trials with fish oil (FO) report various health benefits; however, it remains unclear whether maternal and postnatal consumption of FO protects offspring from adverse effects of consuming a high-fat (HF) diet. METHODS: Female mice were fed HF diets supplemented without (HF) or with FO from 8 weeks before pregnancy through lactation. A low-fat (LF) diet was included as a control diet. After weaning, male offspring from HF or FO dams were either continued on their respective diet (HF-HF and FO-FO) or switched to the other diet (HF-FO and FO-HF) and compared with LF. Phenotypic and mechanistic studies were performed. RESULTS: FO-FO offspring demonstrated significantly higher glucose clearance and insulin sensitivity compared with other pups fed the HF diet (P < 0.05). Furthermore, FO-FO pups had lower adiposity, inflammation, and fat deposition in the liver, consistent with reduced markers of hepatic lipogenesis and increased hepatic lipid oxidation. CONCLUSIONS: Supplementation of FO during pregnancy and early life is more beneficial than treating with FO either during pregnancy or in pups.

PMID- 30281215 TI - CCL21 as a potential biomarker for pulmonary arterial hypertension in systemic sclerosis. AB - We thank Zhou and co-workers for their interest regarding our newly published manuscript on the role of CCL21 in pulmonary arterial hypertension (PAH) associated with systemic sclerosis (SSc). Here, we want to respond to their concerns. Genome-wide association studies (GWASs) have been foreshadowed to be a major advance in biomedical discovery, with many robust associations to complex diseases. However, although there are found polymorphisms with SSc, there are, to date, no existing genetic loci for SSc-PAH. Secondly, despite this success, GWAS studies have met considerable skepticism regarding their clinical applicability; mainly arising from their unclear functional consequences.

PMID- 30281214 TI - Development and validation of a model to predict tyrosine kinase inhibitor sensitive EGFR mutations of non-small cell lung cancer based on multi institutional data. AB - BACKGROUND: Non-small cell lung cancer (NSCLC) with different EGFR mutation types shows distinct sensitivity to tyrosine kinase inhibitors (TKIs). This study developed a patho-clinical profile-based prediction model of TKI-sensitive EGFR mutations. METHODS: The records of 1121 Chinese patients diagnosed with NSCLC from November 2008 to October 2014 (the development set) were reviewed. Multivariate logistic regression was conducted to identify any association between potential predictors and the classic sensitive EGFR mutations (exon 19 deletion and exon 21 L858R point mutation). A prediction index was created by assigning weighted scores to each factor proportional to a regression coefficient. Validation was made in an independent cohort consisting of 864 patients who were consecutively enrolled between November 2014 and January 2017 (the validation set). RESULTS: Seven independent predictors were identified: gender (female vs. male), adenocarcinoma (yes vs. no), smoking history (no vs. yes), N stage (N+ vs. N0), M stage (M1 vs. M0), brain metastasis (yes vs. no), and elevated Cyfra 21-1 (no vs. yes). Each was assigned a number of points. In the validation set, the area under curve of the prediction index appeared as 0.698 (95% confidence interval 0.663-0.733). The sensitivity, specificity, positive and negative predictive values, and concordance were 95.0%, 32.3%, 61.4%, 85.1%, and 65.6%, respectively. CONCLUSION: We developed a patho-clinical profile-based model for predicting TKI-sensitive EGFR mutations. Our model may represent a noninvasive, economical choice for clinicians to inform TKI therapy. PMID- 30281217 TI - CCL21: a potential biomarker for pulmonary arterial hypertension in Systemic Sclerosis? Comment on the article by Hoffmann-Vold et al. AB - We read with great interest the manuscript by Hoffmann-Vold et al, that was published in a recent issue of Arthritis & Rheumatology. They found that serum levels of CCL21 were significantly higher in Systemic Sclerosis (SSc) patients than controls, and elevated prior to pulmonary arterial hypertension (PAH) diagnosis. Moreover, CCL21 serum levels were positively correlated with the PAH and occurrence of PAH related events, which suggested the potential of CCL21 to serve as a promising marker for SSc-PAH risk prediction and PAH progression. However, we have three main concerns regarding using CCL21 as a serum biomarker of SSc-PAH. This article is protected by copyright. All rights reserved. PMID- 30281216 TI - Topotecan monotherapy for the treatment of relapsed small cell lung cancer in elderly patients: A retrospective analysis. AB - BACKGROUND: Topotecan is one of the most active chemotherapeutic drugs for small cell lung cancer (SCLC). However, its efficacy in elderly patients with SCLC has not been validated. This study evaluated the feasibility and efficacy of topotecan monotherapy in elderly patients with relapsed SCLC. METHODS: Between January 2000 and March 2017, 43 patients aged >= 70 years received topotecan monotherapy for relapsed SCLC at four institutions. The clinical outcomes and adverse events of treatment were retrospectively analyzed. RESULTS: Twenty-nine patients (median age 75 years; range: 70-83 years) had sensitive-type relapse, while 14 (median age 78 years; range: 71-82 years) had refractory relapse. The median number of treatment cycles was two (range: 1-6). The response rate was 7.0% (10.3% and 0% in sensitive and refractory patients, respectively), while the disease control rate was 23.2% (20.6% and 42.8% in sensitive and refractory patients, respectively). Median progression-free survival was 1.9 months in sensitive patients and 1.4 months in refractory patients (P = 0.87). The median survival time from the start of topotecan therapy was 5.5 months in sensitive patients and 4.0 months in refractory patients (P = 0.64). Grade >= 3 hematological toxicities were as follows: leukopenia, 37.2%; neutropenia, 51.1%; anemia, 0%; thrombocytopenia, 32.5%; and febrile neutropenia, 9.3%. No treatment related deaths occurred. CONCLUSION: Although hematological toxicities (particularly neutropenia) were severe, topotecan showed favorable disease control in both sensitive and refractory patients. Topotecan may thus be a preferred treatment for elderly patients with relapsed SCLC. PMID- 30281218 TI - [Prevention and treatment of Herpes Labialis]. AB - Herpes labialis, more commonly known as cold sores or fever blisters, is the most common clinical manifestation of infection with Herpes simplex virus type 1. It is a highly contagious and widespread infection. Generally benign, cold sores may however disturb those who suffer from them, because of the symptoms they cause or their unsightly and frequent appearance. The pharmacist is often consulted to relieve cold sore recurrences. As for any request for advice, the pharmacist will assess if he can help the patient himself or if medical advice is more appropriate. Besides a possible symptomatic treatment, the pharmacist will also advise the patient to prevent recurrence and the contamination of other people. PMID- 30281219 TI - [Communication on smoking in community pharmacy. Results of a survey in Belgium]. AB - For several reasons the community pharmacist plays an important role in smoking cessation. In order to know how he is fulfilling this role, a survey was conducted among Belgian community pharmacists on smoking cessation communication in their pharmacy. The pharmacists and the pharmacy personnel were invited to answer an online questionnaire. In community pharmacy the patient is quite often asked if he smokes, however there still remain some obstacles to talk with the patient about smoking behaviour. The major obstacles are lack of time and the fear of a conflict with the patient. The results of the survey reveal that pharmacists and their assistants have a good knowledge of smoking cessation, but there is still some room to improve. In order to improve the smoking cessation support by pharmacists and their assistants, some efforts are necessary to overcome the obstacles. It would also be useful to organise more courses of tabacology at the faculties of pharmacy of the universities and in the continuing education programs for pharmacists.

AB - Osteoporosis is a condition generally associated with olderwomen, but it is rapidly becoming a growing problem for males as well. Screening and treating men early is the only way to address this problem. The known demographic factors of osteoporosis in males such as age, race and BMI as well as secondary causes oflow bone mineral density (BMD) i.e. osteoporosis, have not been well examined in the actual practice settingbased on available literature. This study aims to describe the prevalence of the demographic factors and secondary causes in men with low BMD and also to assess their individual contribution to the overall prevalence. A retrospective chart review of 585 men who underwent bone density scan at the University of Mississippi Medical Center from 2005-2012 was performed. At the time of their scans, patients were also asked to complete a questionnaire assessing demographics, comorbidities, social factors, and medication use. The results suggest that racial difference and differences in secondary causes exist in the epidemiology of male osteoporosis, and this needs to be assessed further. The notion that African American males are protected from OP is unsupported in our data as well as the literature. Overall our research demonstrated that low BMI is the most important factor associated with low BMD in male patients.

AB - Background Medication safety and adherence are important aspects of quality of life, especially for frail elderly in our society. However, many elderly living at home may experience difficulties when taking their medication, and are therefore at risk for medication- related problems. The current living lab was implemented within the framework of the Flanders Care Living Labs and set the objective to develop a care pathway to improve medication safety and adherence for elderly living at home. Automated Individual Medication Preparation [IMP] was provided by a community-pharmacist in order to support frail elderly in taking their medication more correctly and thereby improving adherence. Methods In a before and after study, each patient was supported for 13 weeks through a multidisciplinary care pathway. Key in this pathway was the shared medication schedule (between GP and pharmacist) as the starting point for IMP and medication counselling. The increased medication support based on IMP was evaluated in frail elderly (age a 65 years, complex medication scheme a 5 medicines and a 3 intakes / day) before and after the study, by measuring adherence and satisfaction with counselling and repackaging the medication in sachets. Results The preliminary results of the current study showed that the self-reported adherence rate in frail elderly was significantly higher (p <0.05) after implementation of the pharmacists' intervention with automated IMP. At the end of the study every patient indicated that the repackaging of the medication by dose was helpful in order to take their medication correctly. Conclusion Increased medication counselling with IMP by the community-pharmacist may be a useful aid and supporting tool for frail elderly living at home with a complex medication scheme.

AB - Objectives Assessing the impact of professional practices on a patient's course is an interesting way to optimize health care pathway. The aim of our study is to update and evaluate the compliance to the recommendations of the Societe de Pathologie Infectieuse de Langue Francaise with regards to professional practices and the route of patients admitted to the emergency department of a French military hospital for high urinary tract infection. Patients and methods A retrospective study was carried out on patients admitted to the emergency department and treated for high urinary tract infection from January 1st, 2015 to April 30th, 2015. Clinical and administrative data, medical exams, and antibiotic prescriptions were extracted from computerized patient medical files and from emergency medical files. Results Out of 91 medical cares, 57% were compliant with the recommendations. For 60% of the patients, blood cultures were not argued and in 70% of cases, imaging wasn't justified. Antibiotic prescriptions were not compliant in 31% of cases, mostly due to long prescription durations. Two third of patients received outpatient care. All hospitalizations were argued. Conclusions Drawing up a caring protocol, regularly raising awareness to the good use of antibiotics, as well as reinforcing a cross disciplinary approach will allow optimizing health care pathways for patients coming to the emergency department with high urinary tract infection.

Although it may seem almost insignificant, this practice remains no less an act which involves risks, due to many factors identified. It is therefore important to gather, clarify and communicate the updated information on the modalities of the administration of these injections in order to facilitate and secure the work of the teams of care with a view of an optimal and standardized administration of intravenous medications. Method The tables of standardization of injectable drugs have been made on several occasions in the past and distributed in the care units. The latest version of these documents was reviewed and updated in the light of the recent editions of several sources. The data concerning each individual injectable medicine have individual as well been systematically updates. The updated data have been integrated into the electronic prescription of medicines, a standardized dilution is now proposed by default to the prescriber. For some drugs, special modalities of administration have been planned to meet the specific needs of patients hospitalized in the Intensive Care Unit (ICU). Results The methods for dilution of injections in classical hospitalization have been integrated in the electronic prescribing software (238 "packages" in total. The specific dilutions used in the ICU (48 in total, have been validated but may not be used in the conventional care units. Conclusion All of the information relating to the methods of preparation and administration have been gathered and clarified in order to facilitate and secure the work of the teams of care and thus enable optimal administration of intravenous medications. The information is accessible on paper file and via the internal computer network, the PC of intensive care units and the software Computerized prescription. PMID- 30281229 TI - [Essential oils: good advice by the pharmacist is necessary]. AB - Essential oils are highly concentrated products of a complex composition, obtained from plants. Their therapeutic use relies mostly on tradition and experience. Often few clinical trials are available. The quality and efficacy of only several essential oils are described in the European pharmacopeia and in monographs of the EMA. In addition, essential oils on the Belgian market have different statutes [medicine, food supplement, raw material...]. This results in a complicated legislation. Furthermore, the general public wrongly assumes that essential oils, because of their vegetal origin, can be used at any time without any danger. However, toxicological reactions are described after oral, topical and other routes of administration. Certain precautions need to be taken before using potentially hazardous essential oils. Children and pregnant women are particularly vulnerable populations that need extra attention.

AB - Compounded preparations are an additional therapeutic option besides registered medicines. Because of their <> they have a great value and thus an undeniable place in the therapeutic arsenal available to the physician. To maintain this position, however, they must be of unquestionable quality. Structuring and documenting the compounding operations, incorporating the necessary controls and respect for evident basic rules and precautions can reduce potential errors to a minimum. Pharmacists can rely for this on existing recommendations listed in the different reference books such as the Therapeutic Magistral Form and the Guidelines for Good Officinal Practices, but which aren't always commonly used by pharmacists.

AB - Introduction Pharmacists can be faced with pediatric patients treated for a hemato-oncological condition or patients who underwent a hematopoietic stem cell transplantation [HSCT). This study aims to identify the roLe of the pharmacist and master in pharmacy students as well as their knowLedge of pharmaceutical care for this specific patient population. In addition, their experiences of basic education and expectations of continued education in pediatric hemato-oncology and HSCT are analyzed. Methods Pharmacists in Flanders and pharmacy students [Ghent University] were requested to complete and online survey with (1) general questions, (2) questions about knowledge by means of theoretical examples and practical cases and (3) questions about education (past and future) related to this topic. Results A total of 156 pharmacists and 67 students completed the survey. Results demonstrated that 22.0% of pharmacists and students already delivered medication to this particular patient group. A total of 98.2% [pharmacists and students] found that they had insufficient knowledge and experience to give optimal pharmaceutical advice. The pharmacist scored only 34.0% [average] in the general knowledge section, students 44.0%. Both pharmacists [68.6%] and students [79.0%] agreed that this topic should be included in the basic curriculum. The vas majority [91.0% pharmacists, 89.6% of students] were asking for courses on this theme by means of and evening session or an e-learning tool. Conclusion Although the role of pharmacists and students in this patient group can be confirmed, the results of the survey demonstrate a lack of knowledge among pharmacists and students about pediatric hemato-oncology and HSCT. There is interest in education in the basic curriculum and the vast majority of pharmacists are interested in continuing education.

The course set up at the Faculty of Pharmacy of the University of Montreal in 2011 is a very innovative way to meet this challenge. The purpose of this report is to share this experience by providing a synthetic description. Many students were able to develop new skills and strengthen their skills, including leadership and critical thinking. The Faculty of Pharmacy was also able to achieve greater visibility in the Montreal community, that is to say from the associations, but also with what is out there called the "local health network" linking various health care professionals and institutions. Beyond the quantifiable results, this course is an evolving learning process in which the group interactions, individual and collective values and the task sharing allow students to build a working knowledge of social factors, which d.etermine health problems.

A simultaneous intake of a large number of drugs can possibly lead to drug-related problems due to an increased risk of drug interactions, medication errors, contra-indications, but also a lack of patient compliance. Elderly patients are particularlyvulnerable because of physiological and pathological aging. Therefore we need to be particularly attentive to their medication, especially in case of polypharmacy. A systematic review of the medication for elderly patients should regularly be performed to prevent the occurrence of potentially drug-related problems. In view of his central role in the dispensing of medicines, the pharmacist can carry out this medication review in consultation with the treating physician.

AB - Introduction Pharmacist receive a lot of publicity for OTC products. Often one or more literature references are mentioned to support the advertising claims. Objective In this study we examine: [1) whether the advertising claim is consistent with what is stated in the literature references mentioned on the leaflet and [2] whether these literature references are trustworthy. Method Through 60 randomly selected community pharmacies, pharmacist-directed advertisements for OTC products I= medicines, medical devices, dietary supplements and parapharmacy) with at least one bibliographic reference, were collected. The literature references listed in these leaflets were assessed in terms of content [= is the claim consistent with the information in the reference) and technically [= evaluation of the quality of the references]. Results The 85 collected OTC advertisements made 214 claims that referred to 243 references. Of these, 128 references did not support the promotional claim. The remaining 84 references did support the corresponding claim. From 31 references no full text was obtained. Of the 84 supporting references 44 were of dubious quality. The remaining 40 references were found to be reliable. Conclusion This study shows that the literature references in advertising leaflets for OTC products are not a reliable source of information on the advertised product. Pharmacists should deal critically with this information and should be encouraged to consult reliable scientific sources. PMID- 30281241 TI - [A practical program for outpatient parenteral antimicrobial therapy]. AB - Some infections require prolonged parenteral antimicrobial therapy, which can be continued in an outpatient setting. The Ghent University Hospital has fifteen years of experience with Outpatient Parenteral Antimicrobial Therapy [OPAT) in the patient own home setting. As a quality improvement initiative, this process was critically reviewed in a multidisciplinary approach. Several challenges and barriers were identified, including regulatory obstacles for OPAT in Belgium, such as Lack of uniformity in ambulatory reimbursement of parenteral antimicrobials. There is no financial incentive for the patient with OPAT, as costs for the patient of outpatient therapy can be higher as compared with hospitalization. Other barriers include delayed approval of the certificate for reimbursement, low availability of medicines in the community pharmacies and limited knowledge of the medical devices for administration in ambulatory setting. All critical steps in the revised OPAT program are summarized in a flowchart with a checklist for all stakeholders. Firstly, a list with specific criteria to include patients in an OPAT program is provided. Secondly, the Multidisciplinary Infection Team received a formal mandate to review all eligible OPAT patients. In order to select the most appropriate catheter a decision tree was developed and standardized packages with medical devices were developed. Thirdly, patients receive oral and written information about the treatment with practical and financial implications. Fourthly, information is provided towards the general practitioners, community pharmacists and home care nurses. Standardization of the OPAT-program aims at improving quality and safety of intravenous antimicrobial therapy in the home setting.

AB - Aim Aims are: 1] Identify causes of Drug Related Problems (DRPs), interventions performed by pharmacists and results of corticosteroid- related problems and 2] distinguish between problems related to inhaled and general corticosteroids. Methods During 5 days of their internship, 534 final year students of pharmaceutical sciences in six Belgian universities collected DRPs encountered in community pharmacies, as well as related interventions performed by pharmacists and the result of the intervention. The DRPs' electronic registration was done through an adapted tool for Belgium based on the classification of Pharmaceutical Care Network Europe [PCNE- v 6.2]. Findings The frequency of DRPs is 24,8%. 766 DRPs (4,8%) related to corticosteroids, of which 351 were inhaled corticosteroids. The most common causes of corticosteroid-related problems (53- 59%) were technical causes. The most represented category of clinical causes was the inappropriate choice of drug [33-41%]. Pharmacists' intervention was similar for inhaled and general corticosteroids. Pharmacists intervened orally with patients in 38-40% of total interventions, and in writing in 16% of interventions. Pharmacists did not react in 16% of corticosteroid-related problems. 81-83% of PLMS were resolved partially or completely. Conclusion In conclusion, DRPs detected in community pharmacies related to corticosteroid are infrequent (4,8% of DRPs) but 82% of detected problems have been resolved. Furthermore, the study shows the importance for the Belgian health system to introduce an official DRPs classification and software facilitating their documentation in community pharmacies. PMID- 30281243 TI - [Medication screening by the community pharmacist in Belgium]. AB - About 20% of the European population is older than 65 years. Because of multimorbidity (i.e. multiple chronic condition within a patient), older patients are often prescribed multiple drugs [i.e. polypharmacy). Both older age and polypharmacy significantly increase the risk for adverse drug events. International research showed that more or less 5% of all unplanned hospital admissions is related to the use of medication. About 70% of these drug related admissions happened in patients older than 65 years. Moreover, about half of the admissions could have been avoided. These preventable hospital admissions were caused by the intake of medication without an indication, problems with medication adherence, interactions and/or insufficient monitoring. We define this as (potential Drug Related Problems [DRPI. DRPs can occur on multiple occasions during the medication management process: prescribing, dispensing, intake and monitoring. When DRPs can be detected in an early stage, significant consequences can be avoided. To accomplish this, multiple strategies are possible. One of the possibilities is performing a periodic medication screening by the community pharmacist in patient groups at risk. During such a medication screening, the pharmacotherapy is critically evaluated in a systematic and structured way. The implementation of medication screening in first-line health care is currently limited. The community pharmacist is nevertheless ideally placed to perform this task. There is an important relation of trust between him and the patient and the community pharmacist has access to a full medication history. Furthermore, as an expert in drug-related issues, he possesses all necessary knowledge to perform the pharmacotherapeutic analysis. PMID- 30281244 TI - [Drug-drug interactions with risk of QT-prolongation. A epidemiological study in Belgian community pharmacies]. AB - Introduction Community pharmacists have an important role in the management of drug-drug interactions (DD). One of the interactions that can lead to serious adverse drug events, more specifically Torsade de Pointes and sudden cardiac death, are DDI with risk of CT-prolongation. Many drugs from different therapeutic classes have been linked with the risk of QT-prolongation (as listed in the QT-drug lists of CredibleMeds]. Moreover, patient-specific risk factors should be taken into account. This leads to a complex risk estimation of QT prolongation for each patient. Aim The aim of this study is to investigate the prevalence of DDI and the management of these interactions in community pharmacies, with special attention for DDI with a risk of QT-prolongation. Method This epidemiological study is based on data of an interuniversity, observational study in 534 Belgian community pharmacies with a last-year pharmacy student (November 2012 - March 2013), in which all drug-related problems (DRP) and associated interventions of the pharmacist were registered for drugs on prescription. In this study, all DRP that were registered as a DDI were selected. The evidence for these DD was verified in four information sources (DelphiCare, Medscape, Drugs.com, handbook 'Commentaren Medicatiebewaking'). Finally, an in depth analysis was performed for DDI with risk of QT-prolongation. QT-prolonging drugs were identified with the QT-drug lists of CredibleMeds. Results In total, 64.962 prescriptions and 15.952 DRP were registered in the interuniversity study, of which 1858 DRP (11.6%) described as a DDI that was confirmed in at least one of the information sources. Of these interactions, 223 [12.0%] were linked with a risk of QT- prolongation. The majority of the concerned drugs are situated in list 1 of CredibleMeds (known risk of Torsade de Pointes). In 69 CT-prolonging DDI, two drugs of list 1 were involved. The most frequent QT-prolonging DDI was between escitalopram and quetiapine (N=11J. In 69.5% of the QT-prolonging DDI, an intervention was performed by the community pharmacist. In 47.8% of these interventions, the DDI was discussed with the patient. In 28.3% of the QT prolonging DDI, the pharmacist contacted the physician. However, the proposed intervention was often considered unnecessary by the physician (42.9%). In only 4.5% of the interventions, the involved CT-prolonging drug was replaced by an alternative. Conclusion DDI represent an important part of the DRP in community pharmacies, including DDI with a risk of CT-prolongation (12% of the interactions). In the majority of the QT-prolonging DDI, at least one QT prolonging drug of list 1 of CredibleMeds [known risk of Torsade de Pointes) was involved. In only 4.5% of the interventions, the involved QT-prolonging drug was replaced by an alternative. PMID- 30281245 TI - [Biosimilars, no generic biologicals!]. AB - Biologicals are omnipresent in the current therapeutic arsenal for treating several chronic and life-threatening diseases. Following expiry of patent, 'generic' versions of biological medicines are being developed, so-called biosimilars. In view of their potential to reduce the continuous economic pressure of biologicals on the healthcare system, the eagerness to introduce them at fast rate as alternative treatment options is huge. For all parties involved (patients, physicians, pharmacists and other healthcare professionals), it is of utmost importance to get acquainted with the features of biosimilars. Biosimilars differ from generic drugs as they are, as a result of a complex production process in living organisms, never 100% chemically identical to the originator drug. However, the stringent regulatory pathway for approval requires similarity to the reference biological medicine in terms of biological activity, safety and efficacy. Knowledge on immunogenicity, interchangeability and substitution is constantly evolving. As more biosimilars - possibly of the same reference biological - will entrance the market, traceability becomes key for an efficient pharmacovigilance system. Pharmacists, in their role to advice and support patients, should be adequately trained and have access to relevant information about all aspects on biosimilars.

AB - Objective Is to evaluate the nutritional status of preoperative patients in the visceral surgery department III of CHU Ibn Rushd of Casablanca and to correlate to postoperative length of stay. Patients and methods Prospective observational study of six months from February 2015 to late July 2015, in patients from being operated in the visceral surgery department II1. The nutritional status of 151 patients preoperatively was evaluated the correlation between the various diagnostic tests and clinical and biological parameters was investigated and postoperative length of stay was calculated. Results 151 patients predominantly female (72.84%1, reporting their consent, were selected for this study. 51.56% of patients had risk factors for undernutrition. The cholelithiasis was the most responded diagnosis (57.61%). The Nutritional Risk Index (NRII allowed to identify 13 low nutritional risk patients, 7 moderate-risk and 3 major risk. According to the Mini Nutritional Assessment (MNA two elderly people [over 70 years] were at risk of undernutrition and one person had a bad nutritional status. Nutritional risk stratification identified 19 patients with postoperative nutritional grade 3. The average length of stay was variable; it was not correlated with the nutritional status of patients against it is based on the type of surgery. Conclusion The risk of undernutrition was high; however, a single parameter is insufficient for the diagnosis of preoperative undernutrition, a combination of different parameters would be a more reliable method.

PMID- 30281274 TI - Flexible Peptide Linkers Enhance the Antimicrobial Activity of Surface Immobilized Bacteriolytic Enzymes. AB - Chemical linkers are frequently used in enzyme immobilization to improve enzyme flexibility and activity, whereas peptide linkers, although ubiquitous in protein engineering, are much less explored in enzyme immobilization. Here, we report peptide-linker-assisted noncovalent immobilization of the bacteriolytic enzyme lysostaphin (Lst) to generate anti- Staphylococcus aureus surfaces. Lst was immobilized through affinity tags onto a silica surface (glass slides) and nickel nitrilotriacetic acid (NiNTA) agarose beads via silica-binding peptides (SiBPs) or a hexahistidine tag (His-tag) fused at the C-terminus of Lst, respectively. By inserting specific peptide linkers upstream of the SiBP or His-tag, the immobilized enzymes killed >99.5% of S. aureus ATCC 6538 cells (108 CFU/mL) within 3 h in buffer and could be reused multiple times without significant loss of activity. In contrast, immobilized Lst without a peptide linker was less active/stable. Molecular modeling of Lst-linker-affinity tag constructs illustrated that the presence of the peptide linkers enhanced the molecular flexibility of the proximal Lst binding domain, which interacts with the bacterial substrate, and such increased flexibility correlated with increased antimicrobial activity. We further show that Lst immobilized onto NiNTA beads retained the ability to kill ~99% of a 108 CFU/mL microbial challenge even in the presence of 1% of a commercial anionic surfactant, C12-14 alcohol EO 3:1 sodium sulfate, when the Lst construct contained a decapeptide linker containing glycine, serine, and alanine residues. This linker-assisted immobilization strategy could be extended to an unrelated lytic enzyme, the endolysin PlyPH, to target Bacillus anthracis Sterne cells either in buffer or in the presence of anionic surfactants. Our approach, therefore, provides a facile route to the use of antimicrobial enzymes on surfaces.

AB - Performance of proton-solid oxide fuel cells (H+-SOFC) is governed by ion transport through solid/gas interfaces. Major breakthroughs are then intrinsically linked to a detailed understanding of how parameters tailoring bulk proton conductivity affect surface chemistry in situ, at an early stage. In this work, we studied proton and oxygen transport at the interface between H+-SOFC electrolyte BaCe xZr0.9- xY0.1O2.95 ( x = 0; 0.2; 0.9) thin films and the gas (100 mTorr of H2O and O2) by using synchrotron-based ambient pressure X-ray photoelectron spectroscopy at operating temperature (>400 degrees C). We developed highly textured BaCe xZr0.9- xY0.1O2.95 epitaxial thin films, which exhibit high level of in-plane proton conductivity, that is, up to 0.08 S cm-1 at 500 degrees C for x = 0.9. Upon applying 100 mTorr water partial pressure above 300 degrees C, major changes are observed only in the O 1s and Y 3d core level spectra, with a clear Zr/Ce ratio dependency. OH- formation is favored by Ce content while initiated near Y. Hydration is also associated with surface secondary phase growth comprising oxygen-under-coordinated yttrium and/or yttrium hydroxide. With BaCe0.2Zr0.7Y0.1O2.95, high levels of ionic conductivities and chemical stability are obtained as a result of the optimized surface reaction kinetics, with low activation energy barrier for proton transport while restraining formation of OH-/SO42- adsorb species. PMID- 30281276 TI - Unidirectional Enhanced Emission from 2D Monolayer Suspended by Dielectric Pillar Array. AB - Monolayers of transition metal dichalcogenides show great promise for optoelectronic devices as atomically thin semiconductors. Although dielectric or metal nanostructures have been extensively studied for tailoring and enhancing emission from monolayers, their applications are limited because of the mode concentrating inside the dielectric or the high optical losses in metals, together with the low quantum yield in monolayers. Here, we demonstrate that a metal-backed dielectric pillar array can suspend monolayers to increase the radiative recombination, and simultaneously, create strongly confined band-edge modes on surface directly accessible to monolayers. We observe unidirectional enhanced emission from WSe2 monolayers on polymer pillar array. PMID- 30281277 TI - Cost-Effective, Wireless, Portable Device for Estimation of Hexavalent Chromium, Fluoride, and Iron in Drinking Water. AB - The quality of drinking water often remains unknown to people because of the inadequacy of cost-effective testing systems that can be used in the field. Major portable instruments for water-quality analysis include ion-selective electrodes (ISE) or colorimeters. These are low-cost devices, but in the case of multiple analyte detection, such as that of hexavalent chromium (Cr), fluoride (F-), and iron (Fe), with a single instrument, no portable systems are available, to the authors' knowledge. In this paper, we demonstrate the use of a low-cost (approximate price of INR 1500 or US$20), portable colorimetric system that can be operated with Android smartphones wirelessly to estimate the contamination levels of Cr(VI), F-, and Fe in drinking water. This system also generates absorption spectra by recording the absorbance of the analyte using a light dependent-resistor (LDR) sensor. An Android-application software named Spectruino was developed to calculate the concentrations of the analytes. We strongly believe that this cost-effective, portable system will be very useful in improving human health by ensuring drinking-water quality throughout India. PMID- 30281279 TI - Ion Mobility-Mass Spectrometry Using a Dual-Gated 3D Printed Ion Mobility Spectrometer. AB - Described herein is the development of a 3D-printed drift-tube ion mobility spectrometer (IMS) which operates in the open air and is capable of being coupled to any mass spectrometer. The IMS possesses one electrospray focusing electrode, 31 drift electrodes with 7 mm inner diameters, and 2 ion gates at opposite ends of the IMS, totaling 109 mm in length. The second ion gate was timed with respect to the first ion gate to transmit portions of the separating ion packets to the MS at specified time intervals. By scanning the second ion gate and acquiring mass spectra during each time interval, we reconstructed ion mobility chronograms using mass spectra. Resolving powers of up to 45 were acquired using tetraalkylammonium cations. Separation is also demonstrated for solutions of amphetamines, opioids (fentanyls/fentanils), and bradykinin and angiotensin II. The highest mobility resolving powers were obtained when the injection times of the first and second ion gates were 0.3 and 1.0 ms, respectively. Experiments were performed on both an ion trap and triple quadruple mass analyzer to showcase the adaptability of the plastic IMS. Insights were gained into how ions separate in the open air compared to vacuum conditions with pure gas. PMID- 30281278 TI - Ultrathin Trilayer Assemblies as Long-Lived Barriers against Water and Ion Penetration in Flexible Bioelectronic Systems. AB - Biomedical implants that incorporate active electronics and offer the ability to operate in a safe, stable fashion for long periods of time must incorporate defect-free layers as barriers to biofluid penetration. This paper reports an engineered material approach to this challenge that combines ultrathin, physically transferred films of silicon dioxide (t-SiO2) thermally grown on silicon wafers, with layers of hafnium oxide (HfO2) formed by atomic layer deposition and coatings of parylene (Parylene C) created by chemical vapor deposition, as a dual-sided encapsulation structure for flexible bioelectronic systems. Accelerated aging tests on passive/active components in platforms that incorporate active, silicon-based transistors suggest that this trilayer construct can serve as a robust, long-lived, defect-free barrier to phosphate buffered saline (PBS) solution at a physiological pH of 7.4. Reactive diffusion modeling and systematic immersion experiments highlight fundamental aspects of water diffusion and hydrolysis behaviors, with results that suggest lifetimes of many decades at physiological conditions. A combination of ion-diffusion tests under continuous electrical bias, measurements of elemental concentration profiles, and temperature-dependent simulations reveals that this encapsulation strategy can also block transport of ions that would otherwise degrade the performance of the underlying electronics. These findings suggest broad utility of this trilayer assembly as a reliable encapsulation strategy for the most demanding applications in chronic biomedical implants and high-performance flexible bioelectronic systems.

PMID- 30281281 TI - Radial Growth Evolution of InGaAs/InP Multi-Quantum-Well Nanowires Grown by Selective-Area Metal Organic Vapor-Phase Epitaxy. AB - III-V semiconductor multi-quantum-well nanowires (MQW NWs) via selective-area epitaxy (SAE) is of great importance for the development of nanoscale light emitting devices for applications such as optical communication, silicon photonics, and quantum computing. To achieve highly efficient light-emitting devices, not only the high-quality materials but also a deep understanding of their growth mechanisms and material properties (structural, optical, and electrical) are extremely critical. In particular, the three-dimensional growth mechanism of MQWs embedded in a NW structure by SAE is expected to be different from that of those grown in a planar structure or with a catalyst and has not yet been thoroughly investigated. In this work, we reveal a distinctive radial growth evolution of InGaAs/InP MQW NWs grown by the SAE metal organic vapor-phase epitaxy (MOVPE) technique. We observe the formation of zinc blende (ZB) QW discs induced by the axial InGaAs QW growth on the wurtzite (WZ) base-InP NW and propose it as the key factor driving the overall structure of radial growth. The role of the ZB-to-WZ change in the driving of the overall growth evolution is supported by a growth formalism, taking into account the formation-energy difference between different facets. Despite a polytypic crystal structure with mixed ZB and WZ phases across the MQW region, the NWs exhibit high uniformity and desirable QW spatial layout with bright room-temperature photoluminescence at an optical communication wavelength of ~1.3 MUm, which is promising for the future development of high-efficiency light-emitting devices.

AB - As an omega-conopeptide originally discovered from Conus striatus, SO-3 contains 25 amino acid residues and three disulfide bridges. Our previous study has shown that this peptide possesses potent analgesic activity in rodent pain models (mouse and rat), and it specifically inhibits an N-type calcium ion channel (Cav2.2). In the study presented here, we investigated the key amino acid residues for their inhibitory activity against Cav2.2 expressed in HEK 293 cells and analgesic activity in mice. To improve the inhibitory activity of SO-3, we also evaluated the effects of some amino acid residues derived from the corresponding residues of omega-peptide MVIIA, CVID, or GVIA. Our data reveal that Lys6, Ile11, and Asn14 are the important functional amino acid residues for SO-3. The replacement of some amino acid residues of SO-3 in loop 1 with the corresponding residues of CVID and GVIA improved the inhibitory activity of SO-3. The binding mode of Cav2.2 with SO-3 amino acids in loop 1 and loop 2 may be somewhat different from that of MVIIA. This study expanded our knowledge of the structure-activity relationship of omega-peptides and provided a new strategy for improving the potency of Cav2.2 inhibitors. PMID- 30281284 TI - Anisotropic Near-Zero Thermal Expansion in REAg xGa4- x ( RE = La-Nd, Sm, Eu, and Yb) Induced by Structural Reorganization. AB - In this work, we have discovered the anisotropic near-zero thermal expansion (NZTE) behavior in a family of compounds REAg xGa4- x ( RE = La-Nd, Sm, Eu, and Yb). The compounds adopt the CeAl2Ga2 structure type and were obtained as single crystals in high yield by metal flux growth technique using gallium as active flux. Temperature-dependent single crystal X-ray diffraction suggests that all the compounds exhibit near zero thermal expansion along c direction in the temperature range of 100-450 K. Temperature-dependent X-ray absorption near-edge spectroscopic study confirmed ZTE behavior is due to the geometrical features associated within the crystal structure. The anisotropic NZTE behavior was further established by anisotropic magnetic measurements on selected single crystals. The atomic displacement parameters, apparent bond lengths, bond angles, and structural distortion with respect to the temperature reveal that geometric features associated with the structural distortion cause the anisotropic NZTE along c-direction. The preliminary magnetic studies suggest all the compounds are paramagnetic at room temperature except LaAgGa3. Electrical resistivity study reveals that compounds from this series are metallic in nature. PMID- 30281285 TI - Reduction of Cisplatin-Induced Ototoxicity without Compromising Its Antitumor Activity. AB - Cisplatin is a major chemotherapeutic that continues to have a significant impact in the treatment of more than 50% of all cancers. Since its Food and Drug Administration approval in 1978 for the treatment of advanced ovarian and bladder cancer, this chemotherapeutic has made significant strides and its application has been extended to a large variety of other cancers. However, the vast majority of patients who receive cisplatin therapy often suffer from nephrotoxicity, neurotoxicity, nausea, and ototoxicity. Numerous methods currently exist for overcoming nephrotoxicity- and nausea-related side effects, but there is no clear prevention to fight ototoxicity and neurotoxicity. In this work, we examined Platin- A, a prodrug of cisplatin and aspirin, using preclinical mouse- and guinea pig-based models and demonstrated its efficacy with reduced ototoxicity. In addition, in vitro studies documented that when Platin- A is used in combination with a clinically relevant dose of radiation, its efficacy can further be improved by attacking cellular bioenergetic profiles, producing multiple modes of DNA damage, and delaying repair of damaged DNA. These studies demonstrated novel properties of the prodrug, Platin- A, highlighting its superior efficacy with reduced toxicity.

AB - The conformational analysis of spider dragline silks is difficult because of the amorphous character of the silks. In this article, the fractions of several conformations were determined for three 47-mer peptides, (Glu)4(Ala)6GlyGly12Ala13Gly14GlnGlyGlyTyrGlyGlyLeuGlySerGlnGly25Ala26Gly27 ArgGlyGlyLeuGlyGlyGlnGly35Ala36Gly37(Ala)6(Glu)4, with three underlined 13C labeled blocks using a 13C CP/MAS NMR method. The conformations of the 13C labeled sites change significantly depending on the location of the labeled blocks when treated with trifluoroacetic acid, low pH, and freeze-drying. The conformations of Ala36 and Gly37 residues are strongly influenced by the specific conformation of the (Ala)6 sequence at the C-terminal side, but those of other residues, Ala13 and Gly14, and Ala 26 and Gly27, are basically not influenced by the conformations of (Ala)6. Through hydration of the beta-sheet peptide, sharp peaks with random coil could be observed depending on the position of the residue, and this result could be interpreted via the change in the Ramachandran map obtained from the molecular dynamics simulation.

AB - A highly selective palladium-catalyzed hydroborylative carbocyclization of bisallenes to afford seven-membered rings has been established. This ring-closing coupling reaction showed good functional group compatibility with high chemo- and regioselectivity, as seven-membered ring 3 was the only product obtained. The extensive use of different linkers, including nitrogen, oxygen, malononitrile, and malonate, showed a broad substrate scope for this approach. A one-pot cascade reaction was realized by trapping the primary allylboron compound with an aldehyde, affording a diastereomerically pure alcohol and a quaternary carbon center by formation of a new C-C bond. A comprehensive mechanistic DFT investigation is also presented. The calculations suggest that the reaction proceeds via a concerted hydropalladation pathway from a Pd(0)-olefin complex rather than via a pathway involving a defined palladium hydride species. The reaction was significantly accelerated by the coordination of the pendant olefin, as well as the introduction of suitable substituents in the bridge, due to the Thorpe-Ingold effect. PMID- 30281288 TI - Olefin Metathesis-Based Fluorescent Probes for the Selective Detection of Ethylene in Live Cells. AB - Ethylene is an important plant hormone that is involved in a variety of developmental processes including agriculturally important ripening of certain fruits. Owing to its significant roles, a number of approaches have previously been developed to detect ethylene via molecular interactions. However, there are no current approaches for detection that are selective via a discrete homogeneous molecular interaction. Here we report two profluorescent chemodosimeters for the selective detection of the plant hormone ethylene. The approach consists of a BODIPY fluorophore with a pendant ruthenium recognition element based on a Hoveyda-Grubbs second generation catalysts. A marked increase in fluorescence is observed upon exposure to ethylene and selectivity is observed for ethylene over other alkenes, providing a unique approach toward ethylene detection. Imaging in live cells demonstrated that ethylene could be detected from multiple relevant sources. PMID- 30281289 TI - Terminal Functionalization with a Triptycene Motif That Dramatically Changes the Structural and Physical Properties of an Amorphous Polymer. AB - A surprising terminal-group effect on the structural and physical properties of an amorphous polymer is reported. We recently demonstrated that triptycene derivatives with substituents at the 1,8,13-positions show specific self-assembly behavior, enabling the formation of a well-defined "2D + 1D" structure based on nested hexagonal packing of the triptycenes. Upon terminal functionalization with a 1,8-substituted triptycene (1,8-Trip), a liquid polymer, polydimethylsiloxane (PDMS, Mn = 18-24 kDa), turned into a highly viscous solid that exhibits birefringence at 25 degrees C. Small-angle and wide-angle X-ray scattering measurements revealed that the resulting telechelic PDMS assembles into a 2D + 1D structure, where layers of PDMS domains, formed between 2D assemblies of the triptycene termini, stack into a 1D multilayer structure with a layer spacing of 18-20 nm. Because of this structuring, the complex viscosity of the telechelic PDMS was dramatically enhanced, providing a value 4 orders of magnitude greater than that of the original PDMS. Remarkably, the structural and physical properties of PDMS were hardly changed upon terminal functionalization with another regioisomer of triptycene (1,4-Trip), which differs only in the substitution pattern. PMID- 30281290 TI - Biomolecular Assemblies: Moving from Observation to Predictive Design. AB - Biomolecular assembly is a key driving force in nearly all life processes, providing structure, information storage, and communication within cells and at the whole organism level. These assembly processes rely on precise interactions between functional groups on nucleic acids, proteins, carbohydrates, and small molecules, and can be fine-tuned to span a range of time, length, and complexity scales. Recognizing the power of these motifs, researchers have sought to emulate and engineer biomolecular assemblies in the laboratory, with goals ranging from modulating cellular function to the creation of new polymeric materials. In most cases, engineering efforts are inspired or informed by understanding the structure and properties of naturally occurring assemblies, which has in turn fueled the development of predictive models that enable computational design of novel assemblies. This Review will focus on selected examples of protein assemblies, highlighting the story arc from initial discovery of an assembly, through initial engineering attempts, toward the ultimate goal of predictive design. The aim of this Review is to highlight areas where significant progress has been made, as well as to outline remaining challenges, as solving these challenges will be the key that unlocks the full power of biomolecules for advances in technology and medicine. PMID- 30281292 TI - On Fe-Fe Dumbbells in the Ideal and Real Structures of FeGa3. AB - The intermetallic phase FeGa3 belongs to the rare examples of substances with transition metals where semiconducting behavior is found. The necessary electron count of 17 ve/fu can be formally derived from eight Fe-Ga and one Fe-Fe two center-two-electron bond. The situation is reminiscent of the well-known Fe2(CO)9 scenario, where a direct Fe-Fe two-center-two-electron bond was shown to not be present. Fe-Fe interaction in FeGa3 and its substitution variants represents the crucial point for explanation of electronic, thermal transport, and optical properties of this material. Chemical bonding analysis in position space of FeGa3 and Fe2(CO)9 on the basis of the topology of the electron localizability indicator distribution, QTAIM atoms, two- and three-center delocalization indices, domain natural orbitals, IQA analysis, and an evaluation of the Fe-Fe dissociation energy yields a complete picture of the partially compensated Fe-Fe bond, which is nevertheless strong enough to be of decisive importance. Structural reinvestigation of differently synthesized single crystals leads to the composition Fe1+ xGa3 (0 <= x <= 0.018), where the additional Fe atoms are predicted from DFT/PBE calculations to yield a magnetic moment of about 2 MUB/Fe2 atom and metallic in-gap states. Accompanying magnetization and ESR measurements are consistent with this picture. PMID- 30281291 TI - First Dimethyltin-Functionalized Rare-Earth Incorporated Tellurotungstates Consisting of {B-alpha-TeW7O28} and {W5O18} Mixed Building Units. AB - The facile one-step assembly reaction of Na2WO4.2H2O, Sn(CH3)2Cl2, RE(NO3)3.6H2O and K2TeO3 in the presence of dimethylamine hydrochloride as an organic solubilizing agent in acidic aqueous solution resulted in a family of dimethyltin functionalized rare-earth (RE) incorporated tellurotungstates consisting of {B alpha-TeW7O28} and {W5O18} mixed building units [H2N(CH3)2]8Na4H2[RE2(OH)(B-alpha TeW7O28)Sn2(CH3)4(W5O18)]2.18H2O [RE = ErIII (1), YbIII (2), HoIII (3), YIII (4)]. The most striking structural characteristic of 1-4 is that they all contain a novel tetrameric S-shaped [RE2(OH)(B-alpha-TeW7O28)Sn2(CH3)4(W5O18)]214- moiety simultaneously including two pentavacant Keggin [B-alpha-TeW7O28]12- and two monovacant Lindqvist [W5O18]6- fragments connected by RE and dimethyltin linkers. To the best of our knowledge, such dimethyltin-functionalized RE-containing tellurotungstates have not been reported before. The visible or NIR solid-state emission spectra of 1 and 3 display the characteristic emission bands arising from ErIII and HoIII centers. Moreover, various 1-Er/Yb co-doped samples were prepared by controlling different mass ratio of Er(NO3)3.6H2O/Yb(NO3).6H2O in the range of 0.96:0.04-0.02:0.98. In the visible region, the emission intensity of the 1-Er0.40/Yb0.60 co-doped sample reaches the maximum at the mass ratio of Er(NO3)3.6H2O/Yb(NO3).6H2O being 0.40:0.60, and this observation is mainly derived from the fact that the Yb3+ ions can sensitize the Er3+ ions to enhance the emission intensity in the visible region. However, no such phenomenon for the 1-Er/Yb co-doped samples is seen in the NIR region. Besides, the upconversion spectra of the 1-Er/Yb co-doped samples were first observed. In addition, the thermal stabilities of 1-4 were also investigated on the crystalline samples and the thermal decomposition process of 1 has been deeply studied. PMID- 30281293 TI - Effect of Morphology and Concentration on Crossover between Antioxidant and Pro oxidant Activity of MgO Nanostructures. AB - The toxicity of nanomaterials can sometimes be attributed to photogenerated reactive oxygen species (ROS), but these ROS can also be scavenged by nanomaterials, yielding opportunities for crossover between the properties. The morphology of nanomaterials also influences such features due to defect-induced properties. Here we report morphology-induced crossover between pro-oxidant activity (ROS generation) and antioxidant activity (ROS scavenging) of MgO. To study this process in detail, we prepared three different nanostructures of MgO (nanoparticles, nanoplates, and nanorods) and characterized them by HRTEM. These three nanostructures effectively generate superoxide anions (O2*-) and hydroxyl radicals (*OH) at higher concentrations (>500 MUg/mL) but scavenge O2*- at lower concentrations (40 MUg/mL) with successful crossover at 200 MUg/mL. Nanorods of MgO generate the highest levels of O2*-, whereas nanoparticles scavenge O2*- to the highest extent (60%). Photoluminescence studies reveal that such crossover is based on the suppression of F2+ and the evolution of F+, F2+, and F23+ defect centers. The evolution of these defect centers reflects the antibacterial activity of MgO nanostructures which is initiated at 200 MUg/mL against Gram positive S. aureus ATCC 29737 and among different bacterial strains including Gram-positive B. subtilis ATCC 6633 and M. luteus ATCC 10240 and Gram-negative E. coli ATCC K88 and K. pneumoniae ATCC 10031. Nanoparticles exhibited the highest antibacterial (92%) and antibiofilm activity (17%) against B. subtilis ATCC 6633 in the dark. Interestingly, the nitrogen-centered free radical DPPH is scavenged (100%) by nanoplates due to its large surface area (342.2 m2/g) and the presence of the F2+ defect state. The concentration-dependent interaction with an antioxidant defense system (ascorbic acid (AA)) highlights nanoparticles as potent scavengers of O2*- in the dark. Thus, our findings establish guidelines for the selection of MgO nanostructures for diverse therapeutic applications. PMID- 30281294 TI - Encapsulation of Phosphotungstic Acid into Metal-Organic Frameworks with Tunable Window Sizes: Screening of PTA@MOF Catalysts for Efficient Oxidative Desulfurization. AB - Clean fuels with extremely low sulfur content are highly desirable due to environmental concerns. Herein, three water-stable and eco-friendly metal-organic frameworks with tunable window diameters, denoted as MOF-808X, have been employed as PTA solid supports. An array of PTA@MOF-808X composites were facilely synthesized via the encapsulation strategy. With tunable window sizes and adjustable PTA loading amounts, the obtained PTA@MOF-808X composites were screened for catalytic oxidative desulfurization (ODS) with H2O2 serving as oxidant. The experiments found that 42%PTA@MOF-808A had the highest catalytic ODS activity and could completely remove dibenzothiophene (DBT) in a model fuel with an initial sulfur content of 1000 ppm within 30 min, which falls far below the acceptable limits for fuel standards (10 ppm). Further investigations revealed that this high catalytic activity could be attributed to the cooperative catalysis of metal clusters in the host framework and the guest PTA molecules. Moreover, 42%PTA@MOF-808A could be facilely recovered and reused for at least five runs without loss of catalytic activity. Having a combination of eco sustainability, high stability, high catalytic activity, and good recyclability, 42%PTA@MOF-808A therefore represents a new benchmark material for catalytic ODS and provides a new perspective for ultradeep desulfurization. PMID- 30281295 TI - Seeking Redox Activity in a Tetrazinyl Pincer Ligand: Installing Zerovalent Cr and Mo. AB - Reaction of the readily reduced pincer ligand bis-tetrazinylpyridine, btzp, with the zerovalent metal source M(CO)3(MeCN)3 yields M(btzp)2 for M = Cr, Mo. These diamagnetic molecules show intrapincer bond lengths consistent with major charge transfer from metal to ligand, a result which is further supported by X-ray photoelectron spectroscopy. These molecules show up to five reversible outer sphere electron transfers by cyclic voltammetry. The electronic structure of neutral M(btzp)2 is analyzed by DFT and CASSCF calculations, which reveal the degree of back-donation from the metal into pincer pi* orbitals and also subtle differences in metal-ligand interaction for Mo vs Cr. Near-IR absorptions exhibited by both M(btzp)2 species originate from charge transfer among differently reduced tetrazine rings, which thus further support pincer reduction in these species. PMID- 30281296 TI - Identifying Charge Transfer Mechanisms across Semiconductor Heterostructures via Surface Dipole Modulation and Multiscale Modeling. AB - The design and fabrication of stable and efficient photoelectrochemical devices requires the use of multifunctional structures with complex heterojunctions composed of semiconducting, protecting, and catalytic layers. Understanding charge transport across such devices is challenging due to the interplay of bulk and interfacial properties. In this work, we analyze hole transfer across n Si(111)- R|TiO2 photoanodes where - R is a series of mixed aryl/methyl monolayers containing an increasing number of methoxy units (mono, di, and tri). In the dimethoxy case, triethylene glycol units were also appended to substantially enhance the dipolar character of the surface. We find that hole transport is limited at the n-Si(111)- R|TiO2 interface and occurs by two processes- thermionic emission and/or intraband tunneling-where the interplay between them is regulated by the interfacial molecular dipole. This was determined by characterizing the photoanode experimentally (X-ray photoelectron spectroscopy, voltammetry, impedance) with increasingly thick TiO2 films and complementing the characterization with a multiscale computational approach (first-principles density functional theory (DFT) and finite-element device modeling). The tested theoretical model that successfully distinguished thermionic emission and intraband tunneling was then used to predict the effect of solution potential on charge transport. This prediction was then experimentally validated using a series of nonaqueous redox couples (ferrocence derivatives spanning 800 mV). As a result, this work provides a fundamental understanding of charge transport across TiO2-protected electrodes, a widely used semiconductor passivation scheme, and demonstrates the predictive capability of the combined DFT/device-modeling approach. PMID- 30281297 TI - Molecular Origins of the Apparent Ideal CO2 Solubilities in Binary Ionic Liquid Mixtures. AB - Molecular dynamics (MD) simulations were conducted to investigate the variation of Henry's constant of CO2 in two binary ionic liquid mixtures. One of the mixtures is formed by pairing the cation 1- n-butyl-3-methylimidazolium [C4mim]+ with chloride Cl- and methylsulfate [MeSO4]-, whereas the other binary ionic liquid mixture contains [C4mim]+ in combination with the anions Cl- and bis(trifluoromethanesulfonyl)imide [NTf2]-. In order to provide a microscopic understanding of the behavior of the Henry's constant with the anion composition, MD simulations of ionic liquid mixtures with and without CO2 saturation were performed at 353 K and 10 bar. Our calculations indicate that the Henry's constant for CO2 follows a highly nonlinear, although expected based on ideal solubility, trend with respect to the increasing concentration of Cl- in [C4mim]Cl x[NTf2]1- x, whereas the Henry's constant is almost independent of the anion composition in the [C4mim]Cl x[MeSO4]1- x system. Structural analyses presented in terms of radial, spatial, and angular distribution functions point to significant structural reorganization of the anions around cations in the [C4mim]Cl x[NTf2]1- x system. Because of the weakly coordinating ability of the [NTf2]- anion with the cation, the [NTf2]- anion is displaced from the equatorial plane of the imidazolium ring and occupies positions above and below the ring, enabling enhanced CO2-[NTf2]- association. The rearrangement also weakens the cation pi-pi interactions, resulting in the formation of increased local free volume aiding CO2 accommodation. On the contrary, such structural transitions are absent in the [C4mim]Cl x[MeSO4]1- x mixture system. PMID- 30281298 TI - Linear Bidentate Ligands (L) with Two Terminal Pyridyl N-Donor Groups Forming Pt(II)LCl2 Complexes with Rare Eight-Membered Chelate Rings. AB - NMR and X-ray diffraction studies were conducted on Pt(II)LCl2 complexes prepared with the new N-donor ligands N(SO2R)Me ndpa (R = Me, Tol; n = 2, 4). These ligands differ from N(H)dpa (di-2-picolylamine) in having the central N within a tertiary sulfonamide group instead of a secondary amine group and having Me groups at the 6,6'-positions ( n = 2) or 3,3',5,5'-positions ( n = 4) of the pyridyl rings. The N(SO2R)3,3',5,5'-Me4dpa ligands are coordinated in a bidentate fashion in Pt( N(SO2R)3,3',5,5'-Me4dpa)Cl2 complexes, forming a rare eight membered chelate ring. The sulfonamide N atom did not bind to Pt(II), consistent with indications in the literature that tertiary sulfonamides are unlikely to anchor two meridionally coordinated five-membered chelate rings in solutions of coordinating solvents. The N(SO2R)6,6'-Me2dpa ligands coordinate in a monodentate fashion to form the binuclear complexes [ trans-Pt(DMSO)Cl2]2( N(SO2R)6,6' Me2dpa). The monodentate instead of bidentate N(SO2R)6,6'-Me2dpa coordination is attributed to 6,6'-Me steric bulk. These binuclear complexes are indefinitely stable in DMF- d7, but in DMSO- d6 the N(SO2R)6,6'-Me2dpa ligands dissociate completely. In DMSO- d6, the bidentate ligands in Pt( N(SO2R)3,3',5,5'-Me4dpa)Cl2 complexes also dissociate, but incompletely; these complexes provide rare examples of association-dissociation equilibria of N,N bidentate ligands in Pt(II) chemistry. Like typical cis-PtLCl2 complexes, the Pt( N(SO2R)3,3',5,5' Me4dpa)Cl2 complexes undergo monosolvolysis in DMSO- d6 to form the [Pt( N(SO2R)3,3',5,5'-Me4dpa)(DMSO- d6)Cl]+ cations. However, unlike typical cis PtLCl2 complexes, the Pt( N(SO2R)3,3',5,5'-Me4dpa)Cl2 complexes surprisingly do not react readily with the excellent N-donor bioligand guanosine. A comparison of the structural features of over 50 known relevant Pt(II) complexes having smaller chelate rings with those of the very few relevant Pt(II) complexes having eight membered chelate rings indicates that the pyridyl rings in Pt( N(SO2R)3,3',5,5' Me4dpa)Cl2 complexes are well positioned to form strong Pt-N bonds. Therefore, the dissociation of the bidentate ligand and the poor biomolecule reactivity of the Pt( N(SO2R)3,3',5,5'-Me4dpa)Cl2 complexes arise from steric consequences imposed by the -CH2-N(SO2R)-CH2- chain in the eight-membered chelate ring. PMID- 30281299 TI - The Role of Mixed Amine/Amide Ligation in Nickel Superoxide Dismutase. AB - Superoxide dismutases (SODs) utilize a ping-pong mechanism in which a redox active metal cycles between oxidized and reduced forms that differ by one electron to catalyze the disproportionation of superoxide to dioxygen and hydrogen peroxide. Nickel-dependent SOD (NiSOD) is a unique biological solution for controlling superoxide levels. This enzyme relies on the use of cysteinate ligands to bring the Ni(III/II) redox couple into the range required for catalysis (~300 mV vs. NHE). The use of cysteine thiolates, which are not found in any other SOD, is a curious choice because of their well-known oxidation by peroxide and dioxygen. The NiSOD active site cysteinate ligands are resistant to oxidation, and prior studies of synthetic and computational models point to the backbone N-donors in the active site (the N-terminal amine and the amide N atom of Cys2) as being involved in stabilizing the cysteines to oxidation. To test the role of the backbone N-donors, we have constructed a variant of NiSOD wherein an alanine residue was added to the N-terminus (Ala0-NiSOD), effectively altering the amine ligand to an amide. X-ray absorption, electronic absorption, and magnetic circular dichroism (MCD) spectroscopic analyses of as-isolated Ala0 NiSOD coupled with density functional theory (DFT) geometry optimized models that were evaluated on the basis of the spectroscopic data within the framework of DFT and time-dependent DFT computations are consistent with a diamagnetic Ni(II) site with two cysteinate, one His1 amide, and one Cys2 amidate ligands. The variant protein is catalytically inactive, has an altered electronic absorption spectrum associated with the nickel site, and is sensitive to oxidation. Mass spectrometric analysis of the protein exposed to air shows the presence of a mixture of oxidation products, the principal ones being a disulfide, a bis sulfenate, and a bis-sulfinate derived from the active site cysteine ligands. Details of the electronic structure of the Ni(III) site available from the DFT calculations point to subtle changes in the unpaired spin density on the S-donors as being responsible for the altered sensitivity of Ala0-NiSOD to O2. PMID- 30281300 TI - Time-Dependent Formulation of Resonance Raman Optical Activity Spectroscopy. AB - In this work, we extend the theoretical framework recently developed for the simulation of resonance Raman (RR) spectra of medium-to-large sized systems to its chiral counterpart, namely, resonance Raman optical activity (RROA). The theory is based on a time-dependent (TD) formulation, with the transition tensors obtained as half-Fourier transforms of the appropriate cross-correlation functions. The implementation has been kept as general as possible, supporting adiabatic and vertical models for the PES representation, both in Cartesian and internal coordinates, with the possible inclusion of Herzberg-Teller (HT) effects. Thanks to the integration of this TD-RROA procedure within a general purpose quantum-chemistry program, both solvation and leading anharmonicity effects can be included in an effective way. The implementation is validated on one of the smallest chiral molecule (methyloxirane). Practical applications are illustrated with three medium-size organic molecules (naproxen-OCD3, quinidine and 2-Br-hexahelicene), whose simulated spectra are compared to the corresponding experimental data. PMID- 30281301 TI - S-Nitroso-N-acetylcysteine Generates Less Carcinogenic N-Nitrosamines in Meat Products than Nitrite. AB - Nitrite reacts with secondary amines to form N-nitrosamines (N-NA), which lead to gastrointestinal cancers. The aim of this study was to compare nitrite with S nitrosocysteine (Cys-SNO) and S-nitroso-N-acetylcysteine (NAC-SNO) with respect to N-NA formation, which was evaluated by determining the conversion of N methylaniline to N-nitrosomethylaniline. Under neutral and acidic pH conditions, N-NA formation rate was nitrite > Cys-SNO > NAC-SNO. In the presence of copper or nucleophiles, NAC-SNO generated much less N-NA than Cys-SNO. Nitrite and Cys-SNO produced higher amounts of N-NA in the presence of oxygen, whereas NAC-SNO was almost oxygen insensitive. In meat in the stomach medium, NAC-SNO produced much lower amounts of N-NA than other additives. In heated meat, Cys-SNO and NAC-SNO generated the nitrosyl-hemochrome pink pigment, better than nitrite. In conclusion, NAC-SNO was much less reactive for N-NA formation than nitrite and Cys-SNO in conditions relevant to meat production and stomach digestion. PMID- 30281302 TI - Thermal Gradient Approach for the Quasi-harmonic Approximation and Its Application to Improved Treatment of Anisotropic Expansion. AB - We present a novel approach to efficiently implement thermal expansion in the quasi-harmonic approximation (QHA) for both isotropic and more importantly, anisotropic expansion. In this approach, we rapidly determine a crystal's equilibrium volume and shape at a given temperature by integrating along the gradient of expansion from 0 Kelvin up to the desired temperature. We compare our approach to previous isotropic methods that rely on a brute-force grid search to determine the free energy minimum, which is infeasible to carry out for anisotropic expansion, as well as quasi-anisotropic approaches that take into account the contributions to anisotropic expansion from the lattice energy. We compare these methods for experimentally known polymorphs of piracetam and resorcinol and show that both isotropic methods agree to within error up to 300 K. Using the Gruneisen parameter causes up to 0.04 kcal/mol deviation in the Gibbs free energy, but for polymorph free energy differences there is a cancellation in error with all isotropic methods within 0.025 kcal/mol at 300 K. Anisotropic expansion allows the crystals to relax into lattice geometries 0.01 0.23 kcal/mol lower in energy at 300 K relative to isotropic expansion. For polymorph free energy differences all QHA methods produced results within 0.02 kcal/mol of each other for resorcinol and 0.12 kcal/mol for piracetam, the two molecules tested here, demonstrating a cancellation of error for isotropic methods. We also find that with expansion in more than a single volume variable, there is a non-negligible rate of failure of the basic approximations of QHA. Specifically, while expanding into new harmonic modes as the box vectors are increased, the system often falls into alternate, structurally distinct harmonic modes unrelated by continuous deformation from the original harmonic mode.

AB - The new pyrrole-imidazole and pyrrole-guanidine alkaloids 4-debromooroidin (1), 4 debromougibohlin (2), 5-debromougibohlin (3), and 5-bromopalau'amine (4), along with the known hymenidin (5) and (+)-monobromoisophakellin (6), have been isolated from a Dictyonella sp. marine sponge, collected at the Amazon River mouth. The bromine-substitution pattern observed for compounds 1, 2 and 4 is unusual among bromopyrrole alkaloids isolated from marine sponges. The 20S proteasome inhibitory activities of compounds 1-6 have been recorded, with 5 bromopalau'amine (4) being the most active in this series. PMID- 30281304 TI - Carbide-Supported Au Catalysts for Water-Gas Shift Reactions: A New Territory for the Strong Metal-Support Interaction Effect. AB - Strong metal-support interaction (SMSI) has been regarded as one of the most important concepts in heterogeneous catalysis, which has been almost exclusively discussed in metal/oxide catalysts. Here, we show that gold/molybdenum carbide (Au/MoC x) catalysts feature highly dispersed Au overlayers, strong interfacial charge transfer between metal and support, and excellent activity in the low temperature water-gas shift reaction (LT-WGSR), demonstrating the active SMSI state. Subsequent oxidation treatment results in strong aggregation of Au nanoparticles, weak interfacial electronic interaction, and poor LT-WGSR activity. The two interface states can be transformed into each other by alternative carbonization and oxidation treatments. This work reveals the active SMSI effect in metal/carbide catalysts induced by carbonization, which opens a new territory for this important concept. PMID- 30281305 TI - Preharvest Application of Elicitors to Monastrell Grapes: Impact on Wine Polysaccharide and Oligosaccharide Composition. AB - This work studied the effect of preharvest application in Monastrell grapes of four different elicitors [methyl jasmonate (MeJ), benzothiadiazole (BTH), chitosan from fungi (CHSf), and chitosan from seafood (CHSs)] on wine polysaccharide and oligosaccharide fractions. The polysaccharide and oligosaccharide fractions were isolated and characterized. Neutral monosaccharides were released after hydrolysis of polysaccharides and quantified by gas chromatography (GC). Sugar composition of oligosaccharides was determined after solvolysis by GC of their per-O-trimethylsilylated methyl glycoside derivatives. MeJ, BTH, CHSf, and particularly CHSs decrease the polysaccharide content in wine. The oligosaccharide concentration was also reduced after both CHS treatments. These results pointed to a lower degradation of the skin cell wall from treated grapes. We suggested that the cause would be a reinforcement of the skin cell wall as a result of the action of these elicitors. In conclusion, the application of any of these four elicitors in the clusters of the vineyard affected the complex carbohydrate composition of elaborated wine. PMID- 30281306 TI - Temperature-Dependent Kinetics of the Reaction of a Criegee Intermediate with Propionaldehyde: A Computational Investigation. AB - The temperature-dependent kinetics for the reaction of a Criegee intermediate (CH2OO) with propionaldehyde (CH3CH2CHO) was investigated using canonical variational transition state theory (CVT) in conjunction with the small curvature tunneling (SCT) method and the interpolated single point energy (ISPE) method at the CCSD(T)/AUG-cc-pVTZ//B3LYP/6-311G(d,p) level of theory. A rich chemistry was depicted by the title reaction, though the contributions of all of the reaction pathways were limited to atmospheric pressure conditions. The reaction of CH2OO with CH3CH2CHO was identified to proceed via the formation of secondary ozonide (SOZ), which then underwent a sequence of unimolecular isomerization and decomposition reactions to form a variety of products. The obtained rate coefficient for the formation of SOZ at 298 K was determined to be k = 2.44 * 10 12 cm3 molecule-1 s-1. At low temperature, collisionally stabilized SOZ was found to be the more stable product. Contrarily, at high temperature, SOZ degraded to HCHO, and CH3CH2COOH was found to be the major product. The complete degradation mechanism and thermochemistry for the reaction of CH2OO with CH3CH2CHO along with their rate coefficients over the temperature range of 200-1000 K are reported. PMID- 30281307 TI - Polarizable Drude Model with s-Type Gaussian or Slater Charge Density for General Molecular Mechanics Force Fields. AB - Gas-phase electric properties of molecules can be computed routinely using wave function methods or density functional theory (DFT). However, these methods remain computationally expensive for high-throughput screening of the vast chemical space of virtual compounds. Therefore, empirical force fields are a more practical choice in many cases, particularly since force field methods allow one to routinely predict the physicochemical properties in the condensed phases. This work presents Drude polarizable models, to increase the physical realism in empirical force fields, where the core particle is treated as a point charge and the Drude particle is treated either as a 1 s-Gaussian or a ns-Slater ( n = 1, 2, 3) charge density. Systematic parametrization to large high-quality quantum chemistry data obtained from the open access Alexandria Library ( https://doi.org/10.5281/zenodo.1004711 ) ensures the transferability of these parameters. The dipole moments and isotropic polarizabilities of the isolated molecules predicted by the proposed Drude models are in agreement with experiment with accuracy similar to DFT calculations at the B3LYP/aug-cc-pVTZ level of theory. The results show that the inclusion of explicit polarization into the models reduces the root-mean-square deviation with respect to DFT calculations of the predicted dipole moments of 152 dimers and clusters by more than 50%. Finally, we show that the accuracy of the electrostatic interaction energy of the water dimers can be improved systematically by the introduction of polarizable smeared charges as a model for charge penetration.

AB - Here, we introduce a novel computational method to identify the protein substructures most likely to support the functionally oriented structural deformations that occur upon ligand-binding. To this aim, we study the modulation of protein energetics along the trajectory of a molecular dynamics simulation of different proteins in the presence and in the absence of their respective ligands, namely, human FGF, human second PDZ from human PTP1E/PTPL1, and the N terminal domain of human Hsp90. The method is based on the idea that a subset of protein residues (hotspots) may initiate the global response via the disassembly and reassembly of interactions, which is reflected in the modulation of the overall protein energetics. To identify structural hotspots and dynamic states linked to the onset of functionally relevant conformational transitions, we define an energy profile to monitor the protein energetics, based on a previously introduced approach that highlights the essential nonbonded couplings among all residues. The energy profiles are calculated along the trajectory to yield a time dependent evolution, and their relative population in the presence and absence of the ligand is evaluated by means of a clustering procedure. It is found that interconversion between clusters, as well as their population and the density of specific energy profiles in the vicinity of structural transitions, provides specific information on the impact of the ligand in driving the protein conformational response. This analysis also highlights the hotspot residues that are most responsive to the presence of the ligand. Importantly, identified hotspots are in agreement with experimental evidence in the three considered systems. We propose that this approach can be generally used in the prediction of "allosteric hotspots" and ligand-induced conformational responses, as well as to select conformations more likely to support functional transitions (e.g., in the framework of adaptive sampling approaches).

AB - Three series of isomeric pyrrolo- and furo-fused 7-deazapurine ribonucleosides were synthesized and screened for cytostatic and antiviral activity. The synthesis was based on heterocyclizations of hetaryl-azidopyrimidines to form the tricyclic heterocyclic bases, followed by glycosylation and final derivatizations through cross-coupling reactions or nucleophilic substitutions. The pyrrolo[2',3':4,5]pyrrolo[2,3- d]pyrimidine and furo[2',3':4,5]pyrrolo[2,3- d]pyrimidine ribonucleosides were found to be potent cytostatics, whereas the isomeric pyrrolo[3',2',4,5]pyrrolo[2,3- d]pyrimidine nucleosides were inactive. The most active were the methyl, methoxy, and methylsulfanyl derivatives exerting submicromolar cytostatic effects and good selectivity toward cancer cells. We have shown that the nucleosides are activated by intracellular phosphorylation and the nucleotides get incorporated to both RNA and DNA, where they cause DNA damage. They represent a new type of promising candidates for preclinical development toward antitumor agents. PMID- 30281310 TI - Preferred Binding Mechanism of Osh4's Amphipathic Lipid-Packing Sensor Motif, Insights from Molecular Dynamics. AB - Amphipathic helices are key domains of peripheral membrane proteins, targeting specific membranes to enable proper protein function as well as changing the local topology and lipid dynamics of the membranes they bind. Here, we use extended all-atom molecular dynamics to study, in detail, the binding mechanism and conformation of the N-terminus of the lipid-transport protein Osh4 in yeast, that is, the amphipathic lipid-packing sensor (ALPS) motif. We identified two binding conformations: (i) a vertical one with the N-terminus of the peptide embedded into the hydrophobic core and (ii) a horizontal, and energetically favored, conformation in which the hydrophobic side chains of ALPS are fully embedded into the membrane hydrophobic core. From extensive analysis on 21 trajectories of 2 MUs each, we describe peptide binding in terms of the structural changes that both the peptide and the membrane undergo upon binding as well as energetics of this interaction. The membrane models in this study include a simple binary lipid mixture, with a neutral and a charged lipid (1,2-dioleoyl- sn-glycero-3-phosphocholine-1,2-dioleoyl- sn-glycero-3-phospho-l-serine) and complex mixtures with lipid compositions characteristic of two organelles in yeast (each with more than six lipid types and an accurate sterol content). Our conclusions are in agreement with available literature, showing that the ALPS peptide is more likely to bind membrane surfaces with packing defects and higher anionic character. In addition, we show that there is an interplay between ALPS binding an existing packing defect and creating or enhancing one as the peptide binds to the membrane, which was previously suggested in the literature.

AB - To compute the rate coefficients of the hydrogen abstraction of chlorine plus methane (Me), ethane (Et), and propane (Pr), extensive ring-polymer molecular dynamics (RPMD) calculations are performed in conjunction with the potential energy surface of Cl + Me ( J. Chem. Phys. 2006 , 124 , 124306 ). To treat Cl + Et and Cl + Pr, the recently proposed coarse-grained treatment ( J. Chem. Phys. 2017 , 146 , 024108 ) of RPMD is used. Compared with previous results, good agreement can be found. Several probable reasons for the temperature dependence feature of the rate coefficients of the heavy-light-heavy reactions are discussed through a mass coupling model. PMID- 30281312 TI - Spin-optotronic Properties of Organometal Halide Perovskites. AB - Spin is an intrinsic quantum mechanical property of fundamental particles including the electron. The spin property is intimately related to electronic and optical properties of molecules and materials. The combination of spin (magnetic), electronic, and optical properties of materials, such as organometal halide perovskites (OMHP), has attracted increasing attention, which has led to a new field termed spin-optotronics based on all three key properties. This growing field has implications in emerging technological applications across disciplines, including photonics, electronics, spintronics, quantum computation, and information storage. This Perspective provides a brief introduction to this field from both experimental and computational aspects, with a focus on the effect of spin on charge carrier dynamics in OMHP, a class of materials with novel properties and promising applications in a number of fields. For instance, recent studies have demonstrated the use of ultrafast laser techniques in probing the fundamental charge carrier dynamics in relation to spin properties. Because of strong spin-orbit coupling (SOC) and broken inversion symmetry that result in Rashba and Dresselhaus effects, OMHP are considered ideal for manipulating spin states for spin-optotronics applications. In the meantime, on the basis of first principles calculations and effective model Hamiltonians, the Rashba splitting in locally polarized domains can result in spin-forbidden recombination with significantly slow transition rate due to the mismatch of spin and momentum. We summarize the state-of-the-art first-principles methods and their current limitations for ultrafast charge and spin dynamics for realistic solid-state systems in general. To conclude, we note some promising future research and development directions for both experimental and theoretical ultrafast spin dynamics studies of OMHP.

AB - Most recently, theoretical calculations predicted the stability of a novel two dimensional phosphorus honeycomb lattice named blue phosphorus. Here, we report on the growth of blue phosphorus on Au(111) and unravel its structural details using diffraction, microscopy and theoretical calculations. Most importantly, by utilizing angle-resolved photoemission spectroscopy we identify its momentum resolved electronic structure. We find that Au(111) breaks the sublattice symmetry of blue phosphorus leading to an orbital-dependent band renormalization upon the formation of a (4 * 4) superstructure. Notably, the semiconducting two dimensional phosphorus realizes its valence band maximum at 0.9 eV binding energy, however, shifted in momentum space due to the substrate-induced band renormalization. PMID- 30281316 TI - Nanosecond-Laser-Based Charge Transfer Plasmon Engineering of Solution-Assembled Nanodimers. AB - The ability to re-engineer self-assembled functional structures with nanometer accuracy through solution-processing techniques represents a big challenge in nanotechnology. Herein we demonstrate that Ag+-soldered nanodimers with a steric confinement coating of silica can be harnessed to realize an in-solution nanosecond laser reshaping to form interparticle conductive pathway with finely controlled conductance. The high structural purity of the nanodimers, the rigid silica coating, and the uniform (but still adjustable) sub-1-nm interparticle gap together determine the success of the laser reshaping process. This method is applicable to DNA-assembled nanodimers, and thus promises DNA-based programming toward higher structural complexity. The resulting structures exhibit highly tunable charge transfer plasmons at visible and near-infrared frequencies dictated by the fluence of the laser pulses. Our work provides an in-solution, rapid, and nonperturbative route to realize charge transfer plasmonic coupling along prescribed paths defined by self-assembly, conferring great opportunities for functional metamaterials in the context of chemical, biological, and nanophotonic applications. The ability to continuously control a subnm interparticle gap and the nanomeric width of a conductive junction also provides a platform to investigate modern plasmonic theories involving quantum and nonlocal effects. PMID- 30281314 TI - Acetalated Dextran Microparticles for Codelivery of STING and TLR7/8 Agonists. AB - Vaccines are the most effective tool for preventing infectious diseases; however, subunit vaccines, considered the safest type, suffer from poor immunogenicity and require adjuvants to create a strong and sustained immune response. As adjuvants, pathogen-associated molecular patterns (PAMPs) offer potent immunostimulatory properties and defined mechanisms of action through their cognate pattern recognition receptors (PRRs). Their activity can be further enhanced through combining two or more PAMPs, particularly those that activate multiple immune signaling pathways. However, the cytosolic localization of many PRRs requires intracellular delivery of PAMPs for optimal biological activity, which is particularly true of the stimulator of interferon genes (STING) PRR. Using acetalated dextran (Ace-DEX) microparticles (MPs) encapsulating STING agonist 3'3'-cyclic GMP-AMP (cGAMP) combined with soluble PAMPS, we screened the effect of codelivery of adjuvants using primary mouse bone marrow derived dendritic cells (BMDCs). We identified that codelivery of cGAMP MPs and soluble Toll-like receptor 7/8 (TLR7/8) agonist resiquimod (R848) elicited the broadest cytokine response. cGAMP and R848 were then coencapsulated within Ace-DEX MPs via electrospray. Using the model antigen ovalbumin, we observed that Ace-DEX MPs coencapsulating cGAMP and R848 (cGAMP/R848 Ace-DEX MPs) induced antigen-specific cellular immunity, and a balanced Th1/Th2 humoral response that was greater than cGAMP Ace-DEX MPs alone and PAMPs delivered in separate MPs. These data indicate that polymeric Ace-DEX MPs loaded with STING and TLR7/8 agonists represent a potent cellular and humoral vaccine adjuvant. PMID- 30281317 TI - Size-Dependent Catalytic Activity of Oxo-Hydroxo Titanium Sub-Nanoislets Grafted on Organically Modified Mesoporous Silica. AB - The reaction between titanium alkoxides, [Ti(OR)4], and surface silanol groups is widely used to generate grafted oxo-hydroxo titanium species, whose size is difficult to control. Partial capping of the surface silanols in the presence of the masking pattern of self-repelling tetramethylammonium ions allows us to isolate surface silanol islets, on which isolated titanium ions and dimeric oxo titanium species can be generated up to 2 Ti/Si mol %. Above this loading, and up to ~8 Ti/Si mol %, higher oligomers (trimers, hexamers, octamers, and so on) are formed, reaching the size obtained at much lower loadings (<1 Ti/Si mol %) on a nonmodified silica surface. The downsizing effect produced on our organically modified surface is monitored from the blue-shift of the charge-transfer band of the Ti(IV) ions, measured by reflectance UV-visible spectroscopy. It is also mirrored by a higher catalytic activity in cyclohexene epoxidation, revealing that it is not only the isolated Ti species that are active but also the oligomers. Regarding the latter, the smaller they are, the more active they are. PMID- 30281318 TI - Role of Substrate Stiffness in Tissue Spreading: Wetting Transition and Tissue Durotaxis. AB - Living tissues undergo wetting transitions: On a surface, they can either form a dropletlike cell aggregate or spread as a monolayer of migrating cells. Tissue wetting depends not only on the chemical but also on the mechanical properties of the substrate. Here, we study the role of substrate stiffness in tissue spreading, which we describe by means of an active polar fluid model. Taking into account that cells exert larger active traction forces on stiffer substrates, we predict a tissue wetting transition at a critical substrate stiffness that decreases with tissue size. On substrates with a stiffness gradient, we find that the tissue spreads faster on the stiffer side. Furthermore, we show that the tissue can wet the substrate on the stiffer side while dewetting from the softer side. We also show that, by means of viscous forces transmitted across the tissue, the stiffer-side interface can transiently drag the softer-side interface toward increasing stiffness, against its spreading tendency. These two effects result in directed tissue migration up the stiffness gradient. This phenomenon tissue durotaxis-can thus emerge both from dewetting on the soft side and from hydrodynamic interactions between the tissue interfaces. Overall, our work unveils mechanisms whereby substrate stiffness impacts the collective migration and the active wetting properties of living tissues, which are relevant in development, regeneration, and cancer.

AB - BACKGROUND: The optimal anti-coagulation strategy for patients with non-ST elevation myocardial infarction treated with percutaneous coronary intervention is unclear in contemporary clinical practice of radial access and potent P2Y12 inhibitors. The aim of this study was to investigate whether bivalirudin was superior to heparin monotherapy in patients with non-ST-elevation myocardial infarction without routine glycoprotein IIb/IIIa inhibitor use. METHODS: In a large pre-specified subgroup of the multicentre, prospective, randomised, registry-based, open-label clinical VALIDATE-SWEDEHEART trial we randomised patients with non-ST-elevation myocardial infarction undergoing percutaneous coronary intervention, treated with ticagrelor or prasugrel, to bivalirudin or heparin monotherapy with no planned use of glycoprotein IIb/IIIa inhibitors during percutaneous coronary intervention. The primary endpoint was the rate of a composite of all-cause death, myocardial infarction or major bleeding within 180 days. RESULTS: A total of 3001 patients with non-ST-elevation myocardial infarction, were enrolled. The primary endpoint occurred in 12.1% (182 of 1503) and 12.5% (187 of 1498) of patients in the bivalirudin and heparin groups, respectively (hazard ratio of bivalirudin compared to heparin treatment 0.96, 95% confidence interval 0.78-1.18, p=0.69). The results were consistent in all major subgroups. All-cause death occurred in 2.0% versus 1.7% (hazard ratio 1.15, 0.68 1.94, p=0.61), myocardial infarction in 2.3% versus 2.5% (hazard ratio 0.91, 0.58 1.45, p=0.70), major bleeding in 8.9% versus 9.1% (hazard ratio 0.97, 0.77-1.24, p=0.82) and definite stent thrombosis in 0.3% versus 0.2% (hazard ratio 1.33, 0.30-5.93, p=0.82). CONCLUSION: Bivalirudin as compared to heparin during percutaneous coronary intervention for non-ST-elevation myocardial infarction did not reduce the composite of all-cause death, myocardial infarction or major bleeding in non-ST-elevation myocardial infarction patients receiving current recommended treatments with modern P2Y12-inhibitors and predominantly radial access. PMID- 30281322 TI - USP10 promotes proliferation and migration and inhibits apoptosis of endometrial stromal cells in endometriosis through activating the Raf-1/MEK/ERK pathway. AB - Endometriosis has been initially described as endometrial-like tissue outside of the uterine cavity. Mitogen-activated protein kinase/ERK kinase (MEK)/extracellular-signal-regulated kinase (ERK) signaling pathway playing an important role in the regulation of cell proliferation, apoptosis and migration has been found to be activated in endometriosis. However, the regulation of MEK/ERK signaling pathway in endometriosis has not been fully understood. In this study, primary-cultured endometrial stromal cells were collected from patients with endometriosis and healthy controls, and the proliferation, apoptosis and migration of ectopic endometrial stromal cells transfected with ubiquitin specific protease 10 (USP10)-siRNA or pLVX-Puro-USP10 with or without MEK inhibitor PD98059 or exogenous signaling stimulation such as epidermal growth factor (EGF) were measured by CCK-8, flow cytometry and Transwell, respectively. The gene and protein expressions were measured by Real-time PCR or western blot. USP10 overexpression promoted ectopic endometrial stromal cell migration and proliferation, suppressed cell apoptosis, and activated MEK/ERK signaling that is a critical downstream target of the serine/threonine protein kinase Raf-1, which was significantly blocked by PD98059. USP10 silencing demonstrated the inverse effects, and these effects induced by USP10 silencing were significantly blocked by EGF. USP10 overexpression promoted Raf-1 protein expression, but not the mRNA expression, through deubiquitination. In conclusion, these results suggest that USP10 promotes proliferation and migration and inhibits apoptosis of endometrial stromal cells in endometriosis through activating the Raf-1/MEK/ERK pathway. PMID- 30281323 TI - Mammalian skeletal muscle does not express functional voltage-gated H+ channels. AB - High metabolic activity and existence of a large transmembrane inward electrochemical gradient for H+ at rest promote intracellular acidification of skeletal muscle. Exchangers and cotransports efficiently contend against accumulation of intracellular H+ and associated deleterious effects on muscle functions. Voltage-gated H+ channels have also been found to represent another H+ extrusion pathway in cultured muscle cells. Up to now, the skeletal muscle cell was therefore the unique vertebrate excitable cell in which voltage-gated H+ currents have been described. In this study, we show that, unlike cultured cells, single mouse muscle fibers do not generate H+ currents in response to depolarization. In contrast, expression of human voltage-gated H+ channels in mouse muscle gives rise to robust outward voltage-gated H+ currents. This result excludes that inappropriate experimental conditions may have failed to reveal voltage-gated H+ currents in control muscle. This work therefore demonstrates that fully differentiated mammalian muscle fibers do not express functional voltage-gated H+ channels and consequently can be no more considered as the only vertebrate excitable cells exhibiting voltage-gated H+ currents.

AB - RATIONALE: Neutrophils are recruited to the airways of individuals with cystic fibrosis (CF).In adolescents and adults with CF, airway neutrophils actively exocytose the primary granule protease elastase (NE), whose extracellular activity correlates with lung damage. During childhood, free extracellular NE activity is measurable only in a subset of patients, and the exocytic function of airway neutrophils is unknown. OBJECTIVE: We sought to measure NE exocytosis by airway neutrophils in relation to free extracellular NE activity and lung damage in CF children. METHODS: We measured lung damage using chest computed tomography (CT) coupled with the PRAGMA-CF scoring system. Concomitantly, we phenotyped blood and bronchoalveolar lavage fluid (BALF) leukocytes by flow and image cytometry, and measured free extracellular NE activity using spectrophotometric and Forster resonance energy transfer (FRET) assays. Children with airway inflammation linked to aerodigestive disorder were enrolled as controls. MEASUREMENTS AND MAIN RESULTS: CF but not disease control children harbored BALF neutrophils with high exocytosis of primary granules, prior to the detection of bronchiectasis. This measure of NE exocytosis correlated with lung damage (Rho=0.55, p=0.0008), while the molecular measure of free extracellular NE activity did not. This discrepancy may be due to the inhibition of extracellular NE by BALF antiproteases and its binding to leukocytes. CONCLUSIONS: NE exocytosis by airway neutrophils occurs in all CF children, and its cellular measure correlates with early lung damage. These findings implicate live airway neutrophils in early CF pathogenesis, which should instruct biomarker development and anti-inflammatory therapy in CF children. PMID- 30281326 TI - Activation of u-opioid receptors in the rostral ventrolateral medulla blocks the sympathetic counter-regulatory response to glucoprivation. AB - Activation of neurons in the rostral ventrolateral medulla (RVLM) following glucoprivation initiates sympathoadrenal activation, adrenaline release, and increased glucose production. Here, we aimed to determine the role of RVLM u opioid receptors in the counter-regulatory response to systemic glucoprivation. Experiments were performed in sodium pentobarbital anaesthetised male Sprague Dawley rats (n=30). Bilateral activation of RVLM u-opioid receptors with DAMGO (8mM, 50nl) depressed adrenal sympathetic nerve activity (ASNA), for ~60 minutes (n=6; Delta 49.9+/-5.8%, P<0.05). The counter-regulatory response to glucoprivation (measured by adrenal sympathetic efferent nerve activity) induced by 2-deoxyglucose (2-DG) (n=6; Delta63.6+/-16.5%, P<0.05) was completely blocked 60 minutes after DAMGO microinjections (n=6; Delta-10.2+/-3.5%, P<0.05). Furthermore, DAMGO pre-treatment attenuated the increase in blood glucose levels following 2-DG infusion (n=6; 6.1+/-0.7mmol/L vs baseline 5.2+/-0.3mmol/L, P>0.05) compared to 2-DG alone (n=6; 7.6+/-0.4mmol/L vs baseline 6.0+/-0.4mmol/L, P<0.05). Thus, activation of RVLM u-opioid receptors attenuated the neural efferent response to glucoprivation, and reduced glucose production. PMID- 30281327 TI - Effect of anatomical change on dose distribution during radiotherapy for maxillary sinus carcinoma: passive scattering proton therapy versus volumetric modulated arc therapy. AB - OBJECTIVE:: Maxillary sinus carcinomas are anatomically situated next to many organs at risk (OARs), and anatomical change is often observed during radiotherapy. We analyzed the effect of anatomical change on dose distribution of passive scattering proton therapy (PSPT) and volumetric-modulated arc therapy (VMAT) for 20 patients. METHODS:: The first plans were generated based on the first CT images. The second CT images were acquired after 3 weeks, and the second plans were generated by copying the first plans to the second CT images. The effect of anatomical change was estimated by comparing both plans. RESULTS:: Target volume change was observed in all cases, however, the influence on dose coverage of clinical target volume tended to be small. Alternatively, the doses to almost all OARs were increased. In particular, the increase in the dose to brainstem (p < 0.001) and optic chiasm (p < 0.001) was significantly higher in the second PSPT plan than in the first PSPT plan. Although PSPT is sensitive to anatomical change, the dose to OARs remained significantly lower in PSPT plans than that in VMAT plans. CONCLUSION:: PSPT was confirmed to be more effective than VMAT even the effect of anatomical change was taken into account. Therefore, it is expected that the contralateral vision can be preserved reliably while optimal target coverage is provided. ADVANCES IN KNOWLEDGE:: PSPT allowed significant sparing of OARs even in the result of the second plans affected by the anatomical change. PSPT offers benefits over VMAT in reducing dose to several OARs. PMID- 30281328 TI - Dusting Off Interleukin-9 as a New Therapeutic Target for Pulmonary Fibrosis. PMID- 30281329 TI - Feasibility of deriving a novel imaging biomarker based on patient-specific lung elasticity for characterizing the degree of COPD in lung SBRT patients. AB - OBJECTIVE:: Lung tissue elasticity is an effective spatial representation for Chronic Obstructive Pulmonary Disease phenotypes and pathophysiology. We investigated a novel imaging biomarker based on the voxel-by-voxel distribution of lung tissue elasticity. Our approach combines imaging and biomechanical modeling to characterize tissue elasticity. METHODS:: We acquired 4DCT images for 13 lung cancer patients with known COPD diagnoses based on GOLD 2017 criteria. Deformation vector fields (DVFs) from the deformable registration of end inhalation and end-exhalation breathing phases were taken to be the ground-truth. A linear elastic biomechanical model was assembled from end-exhalation datasets with a density-guided initial elasticity distribution. The elasticity estimation was formulated as an iterative process, where the elasticity was optimized based on its ability to reconstruct the ground-truth. An imaging biomarker (denoted YM1 3) derived from the optimized elasticity distribution, was compared with the current gold standard, RA950 using confusion matrix and area under the receiver operating characteristic (AUROC) curve analysis. RESULTS:: The estimated elasticity had 90 % accuracy when representing the ground-truth DVFs. The YM1-3 biomarker had higher diagnostic accuracy (86% vs 71 %), higher sensitivity (0.875 vs 0.5), and a higher AUROC curve (0.917 vs 0.875) as compared to RA950. Along with acting as an effective spatial indicator of lung pathophysiology, the YM1-3 biomarker also proved to be a better indicator for diagnostic purposes than RA950. CONCLUSIONS:: Overall, the results suggest that, as a biomarker, lung tissue elasticity will lead to new end points for clinical trials and new targeted treatment for COPD subgroups. ADVANCES IN KNOWLEDGE:: The derivation of elasticity information directly from 4DCT imaging data is a novel method for performing lung elastography. The work demonstrates the need for a mechanics based biomarker for representing lung pathophysiology. PMID- 30281330 TI - The potential impact of ultrathin filter design on dosimetry and relative biological effectiveness in modern image-guided small animal irradiators. AB - OBJECTIVE:: Modern image-guided small animal irradiators like the Xstrahl Small Animal Radiation Research Platform (SARRP) are designed with ultrathin 0.15 mm Cu filters, which compared with more heavily filtrated traditional cabinet-style biological irradiators, produce X-ray spectra weighted toward lower energies, impacting the dosimetric properties and the relative biological effectiveness (RBE). This study quantifies the effect of ultrathin filter design on relative depth dose profiles, absolute dose output, and RBE using Monte Carlo techniques. METHODS:: The percent depth-dose and absolute dose output are calculated using kVDoseCalc and EGSnrc, respectively, while a tally based on the induction of double-strand breaks as a function of electron spectra invoked in PENELOPE is used to estimate the RBE. RESULTS:: The RBE increases by >2.4% in the ultrathin filter design compared to a traditional irradiator. Furthermore, minute variations in filter thickness have notable effects on the dosimetric properties of the X-ray beam, increasing the percent depth dose (at 2 cm in water) by + 0.4%/0.01 mm Cu and decreasing absolute dose (at 2 cm depth in water) by 1.8%/0.01 mm Cu for the SARRP. CONCLUSIONS:: These results show that modern image guided irradiators are quite sensitive to small manufacturing variations in filter thickness, and show a small change in RBE compared to traditional X-ray irradiators. ADVANCES IN KNOWLEDGE:: We quantify the consequences of ultrathin filter design in modern image-guided biological irradiators on relative and absolute dose, and RBE. Our results show these to be small, but not insignificant, suggesting laboratories transitioning between irradiators should carefully design their radiobiological experiments. PMID- 30281331 TI - Adverse effects and radiological manifestations of new immunotherapy agents. AB - Immunotherapy has had increasing use in Medical Oncology for a diverse range of primary malignancies. There are various types of immunotherapy which are grouped based on mechanism of action. In recent decades, the immune checkpoint inhibitors (ICI) immunotherapies have been at the forefront of Medical Oncology, sparked by very encouraging results. Some patients with metastatic cancer who were previously deemed palliative were seeing durable response rates and significant increased survival with ICIs. The mechanism of action of ICIs vary wildly compared to the conventional, cytotoxic chemotherapy, upon which traditional radiology response criteria were based and validated upon. Novel responses such as pseudo progression, disease response in the context of new metastases and prolonged stable disease were observed and correlated with improved patient survival with ICI. New radiology response criteria were proposed to better capture disease response to ICI; however, the criteria have been applied heterogeneously and there is continued work in this sector. In addition to the novel responses, ICIs have been linked to numerous, diverse immune-related adverse events (irAE) affecting multiple systems. A large majority of these are mild, but some irAEs are life threatening. Only some of the irAEs have radiological manifestations. It is important that the reporting radiologist recognises potential irAE so clinical teams can be alerted, ICI treatment paused or cessated and steroid treatment initiated. This review will discuss the evolution of the radiology response criteria in ICI and the varied radiological appearances of irAE. PMID- 30281332 TI - TREM-1 Attenuates RIPK3 Mediated Necroptosis in Hyperoxia Induced Lung Injury in Neonatal Mice. AB - Hyperoxia-induced injury to the developing lung, impaired alveolarization and dysregulated vascularization are critical factors in the pathogenesis of bronchopulmonary dysplasia (BPD); however, mechanisms for hyperoxia-induced development of BPD are not fully known. Here we show that the triggering receptor expressed on myeloid cells 1 (TREM-1) is upregulated in hyperoxia-exposed neonatal mice lungs as well as in tracheal aspirates (TA) and lungs of human neonates with respiratory distress syndrome (RDS) and BPD as an adaptive response to survival in hyperoxia. Inhibition of TREM-1 function using siRNA approach or deletion of TREM-1 gene in mice showed enhanced lung inflammation, alveolar damage and mortality of hyperoxia-exposed neonatal mice. The treatment of hyperoxia-exposed neonatal mice with agonistic TREM-1 antibody decreased lung inflammation, improved alveolarization and was associated with diminished necroptosis regulating protein receptor-interacting protein kinase 3 (RIPK3). Mechanistically, we show that TREM-1 activation alleviates lung inflammation and improves alveolarization through down-regulating RIPK3 mediated necroptosis and nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 (NLRP3)-inflammasome activation in hyperoxia-exposed neonatal mice. These data show that activating TREM-1, enhancing angiopoietin 1 signaling or blocking RIPK3 mediated necroptosis pathway may act as new therapeutic interventions to control adverse effects of hyperoxia on the development of BPD. PMID- 30281333 TI - Ski Boots Do Not Impair Standing Balance by Restricting Ankle-Joint Mobility. AB - OBJECTIVE: This study was undertaken in order to provide new insight into sensorimotor control of posture when wearing high-shaft (HS) boots as ski boots. BACKGROUND: Previous studies into the effects of HS boots on postural control have produced controversial results. Some studies reported postural control impairments with ski boots in bipedal postural tasks due to ankle movement restrictions without quantifying the actual restrictive effect of these boots and specifying the adaptations of the postural control system. METHOD: Eighteen young healthy subjects took part in the experiment. Bilateral postural control was assessed on stable and unstable surfaces, while standing barefoot or wearing ski boots. Center of pressure (COP) parameters, ankle, knee, and hip joints movements were calculated and EMG activity from main postural muscles was recorded. RESULTS: Ski boots did not restrict the amplitude of ankle angular movements and largely impacted COP parameters and EMG activity on stable ground. In conditions of mediolateral instability, COP data illustrated an enhanced postural control in the frontal plane when wearing ski boots. CONCLUSIONS: Ski boots do not affect bipedal postural balance by restricting the ankle angular motions but induce complex adaptations of the postural control system which combine factors of a mechanical, motor, and sensorial nature. They impede postural control mainly when standing on stable ground without producing similar deleterious effects on unstable surfaces. APPLICATION: Our results show that HS boots as ski boots can improve lateral balance on unstable surfaces, which can contribute to prevent fall risk and ankle sprain. PMID- 30281334 TI - Effects of Display Curvature, Presbyopia, and Task Duration on Visual Fatigue, Task Performance, and User Satisfaction. AB - OBJECTIVE: This study examined the effects of display curvature, presbyopia, and task duration on visual fatigue, task performance, and user satisfaction. BACKGROUND: Although curved displays have been applied to diverse display products, and some studies reported their benefits, it is still unknown whether the effects of display curvature are presbyopia-specific. METHOD: Each of 64 individuals (eight nonpresbyopes and eight presbyopes per display curvature) performed four 15-min proofreading tasks at one display curvature radius setting (600R, 1140R, 4000R, and flat; mm). Diverse measurements were obtained to assess visual fatigue, task performance, and user satisfaction. RESULTS: The mean pupil diameter was the largest with 1140R, indicating this curvature radius was associated with the least development of visual fatigue; 600R was comparable with 1140R in terms of pupil diameter. The presbyopic group showed a 28.5% slower proofreading speed compared with the nonpresbyopic group, whereas their proofreading accuracy was comparable. For both groups, the mean visual fatigue increased significantly during the first 15 min of proofreading, as indicated by a decrease of 0.11 mm in the mean pupil diameter, an increase of 3.8 in the mean bulbar conjunctival redness, and an increase of 9.13 in the mean eye complaint questionnaire score. CONCLUSION: The effect of display curvature was not presbyopia-specific. Low visual fatigue was observed with 1140R and 600R. APPLICATION: Display curvature radii near or in the range of 600R and 1140R and frequent breaks are recommended for both presbyopic and nonpresbyopic groups to reduce their visual fatigue due to visual display terminal tasks.

AB - Neutrophil recruitment and plasma exudation are key elements in the immune response to injury or infection. Activated neutrophils stimulate opening of the endothelial barrier; however, the underlying mechanisms have remained largely unknown. In this study, we identified a pivotal role of the proinflammatory kallikrein-kinin system and consequent formation of bradykinin in neutrophil evoked vascular leak. In mouse and hamster models of acute inflammation, inhibitors of bradykinin generation, and signaling markedly reduced plasma exudation in response to chemoattractant activation of neutrophils. The neutrophil-driven leak was likewise suppressed in mice deficient in either the bradykinin B2 receptor or factor XII (initiator of the kallikrein-kinin system). In human endothelial cell monolayers, material secreted from activated neutrophils induced cytoskeletal rearrangement, leading to paracellular gap formation in a bradykinin-dependent manner. As a mechanistic basis, we found that a neutrophil-derived heparin-binding protein (HBP/azurocidin) displaced the bradykinin precursor high-molecular-weight kininogen from endothelial cells, thereby enabling proteolytic processing of kininogen into bradykinin by neutrophil and plasma proteases. These data provide novel insight into the signaling pathway by which neutrophils open up the endothelial barrier and identify the kallikrein-kinin system as a target for therapeutic interventions in acute inflammatory reactions.-Kenne, E., Rasmuson, J., Renne, T., Vieira, M.

Weitzenkamp, Javier Gutierrez, Peppi Koivunen, Colleen G. Julian, and Lorna G. Moore. Gestational diabetes prevalence at moderate and high altitude. High Alt Med Biol. 00:000-000, 2018. BACKGROUND: High-altitude (HA) pregnancies have been associated with decreased glucose levels and increased insulin sensitivity versus sea level. Our objective was to determine if the prevalence of gestational diabetes mellitus (GDM) and the impact of demographic characteristics on GDM diagnosis differed at moderate altitude (MA) versus HA. METHODS: Using a retrospective cohort design, we compared women living at HA (>8250 ft) and MA (4000-7000 ft) during pregnancy. Exclusion criteria were as follows: multiple gestation, preexisting diabetes, unavailable GDM results, or relocation from a different altitude during pregnancy. GDM diagnosis was determined using Carpenter and Coustan criteria. Data were compared by t-test (continuous variables) or chi squared tests (categorical variables). Univariate, multivariate, and stepwise regression models were used to assess the impact of various factors on GDM prevalence. RESULTS: There was no difference in GDM prevalence between altitudes in these populations; the relationship between altitude and GDM was nonsignificant in all regression analyses. At MA, maternal age, Hispanic ethnicity, body mass index (BMI), and gestational age (GA) at testing increased GDM incidence in univariate analyses. At HA, maternal age, Hispanic ethnicity, and multiparity increased GDM incidence in univariate analyses. CONCLUSION: While GDM prevalence did not differ between MA and HA, the impact of maternal demographic characteristics on GDM risk varied by altitude group. Higher BMI and greater GA at testing increased the incidence of GDM at MA, but not at HA. Multiparity had an effect at HA, but not MA. These differences may represent subtle differences in glucose metabolism at HA. PMID- 30281339 TI - Keeping clinical skills updated.

AB - Intensive care unit (ICU) diaries are increasingly being used in UK hospitals as a therapeutic means to address the psychological effects of an ICU stay on patients. The National Institute for Health and Care Excellence recommends that services are developed to meet the psychological needs of patients following critical illness. This article discusses ICU diaries as a service to meet these needs. There is a greater demand for evidence-based research to support the positive effects of the diaries. Equally, there is a need to highlight the negative impact they may have on patients who would not wish to have a diary because of the traumatic experience of critical illness. To gain an insight into the use of patient diaries, an audit was conducted at one ICU, which found compliance with completing them was poor. This article gives an overview of the available literature. Recommendations are made to improve the use of ICU diaries for clinical practice in the future.

The impact of nasal bridle securement on nasogastric (NG) and nasointestinal (NI) tube loss, outcome and duration of use was determined from 1 October 2014 (NG) and 1 January 2010 respectively to 31 December 2017. From this and published data, the potential impact of nasal bridles on major complications was determined. Use of nasal bridles was independently associated with: an 80% reduction in inadvertent NI tube loss (odds ratio (OR): 95% confidence interval (CI): 0.2: 0.12-0.33, p<0.0001); increased duration of tube use (2.2 days, 95% CI: 0.7-3.7, p= 0.004); and an almost threefold likelihood of tubes being used until no longer needed (OR: 2.8, 95%CI: 1.9-4.3, p<0.0001). In a single-room intensive care unit, inadvertent tube loss dropped from 53% to 9% and tube redundancy (tube no longer required) rose from 20% to 64%. UK-wide bridle securement, by reducing premature tube loss and the need for replacement by 40%, could be associated with 1422 fewer pneumonias or pneumothoraces and 768 fewer deaths.

PMID- 30281349 TI - Immunosuppression following organ transplantation. Part 2: complications and their management. AB - Advances in the care of patients who have had a solid organ transplant has led to a growing population of post-transplant patients, who are also living for longer. As a result of their longer life expectancy, transplant recipients often face a multitude of challenges, including optimising their immunosuppressive regimens and managing potential complications. Life-threatening infections, malignancies, and organ-specific toxicities are the complications post-transplant patients commonly encounter and these complications are often associated with increased morbidity and mortality, adverse graft functioning and survival, profound impairment in the patient's quality of life, and significant healthcare burden. This article, the second of two parts, gives an overview of the issues involved in the care of patients who are receiving immunosuppressants. The common complications encountered by post-transplant patients are discussed and their assessment, management, prevention and treatment explored.

AB - Following its consultation with key stakeholder groups the Nursing and Midwifery Council (NMC) has launched Future nurse: standards of proficiency for registered nurses ( NMC, 2018a ). These compulsory new standards will be available for use in curricula by approved education institutions (AEIs) from the end of January 2019. In this article, the authors provide their personal perspectives on the potential impact of the new standards, particularly focusing on those relating to supporting and assessing students from within the practice environment. The new roles of practice supervisor, practice assessor and academic assessor are explored, making comparisons to the current mentorship role. There is a clear need for effective partnerships between AEIs and healthcare organisations as they lead on the implementation of the standards. They must think creatively about practice placements and provide opportunities for interprofessional supervision, so that students can learn about the roles of other disciplines and how to collaborate in a multidisciplinary team.

AB - A newly built NHS 'one-stop' urology diagnostics unit has been created to provide a genuinely patient-centred experience for all new patients presenting with urological symptoms. Patients across the region now receive not only their initial specialist consultation, but also all diagnostic investigations and a treatment plan during a single visit to the unit. The purpose-built service has reduced the patient diagnostic pathway from several visits over many weeks to a matter of hours. The unit has facilities for urodynamic studies, ultrasound, flexible cystoscopy and trans-rectal ultrasound prostate biopsy in addition to full physiological measurement capabilities. Designing a new purpose-built unit in the current healthcare climate brought its own challenges as the project progressed. Having the right nursing team in place was essential, and this article describes the insights afforded in developing the project.

AB - Pressure ulcers (PUs) are caused by tissue damage when the blood supply to an area of skin is diminished as a result of pressure. Although most pressure ulcers are preventable, all patients are at risk. Nurses have a central role in prevention and management of pressure areas. They should be able to assess patients' risk of developing PUs using evidence-based practice, recognised risk assessment tools and by completing a holistic assessment. Nurses must be able to identify the risk factors associated with developing PUs and implement appropriate measures to deliver harm-free care. Repositioning techniques, monitoring and ongoing care strategies are essential for pressure ulcer prevention in practice. PMID- 30281356 TI - Bladder cancer: overview and management. Part 2: muscle-invasive and metastatic bladder cancer. AB - This is Part 2 of an article on bladder cancer: an overview of disease and its management. Part 1 provided an overview of non-muscle-invasive bladder cancer, how the disease presents, is diagnosed and subsequently treated ( Anderson, 2018 ). Part 2 provides an overview of muscle-invasive and metastatic bladder cancer and outlines treatment options currently available to manage the relevant stages of the disease. The management of muscle-invasive cancers comprise surgical intervention with transurethral resections, cystectomy (removal of the bladder), and systemic chemotherapy and radiotherapy (multi-modality treatment). For locally advanced and metastatic disease, systemic chemotherapy and radiotherapy are offered, but only as a palliative measure. The intent of treatments for muscle-invasive disease is curative. For metastatic disease, the intent is disease control, extending life, managing symptoms and improving quality-of-life outcomes. This article will include the treatments for the relevant stage of muscle-invasive and metastatic bladder cancer and highlight the respective risks and benefits. The risk factors for bladder cancer, such as smoking, and risks associated with relevant treatments are discussed. The role of the multidisciplinary team is underlined in the management of bladder cancer, specifically the role of the uro-oncology cancer nurse specialist in the provision of reassurance and support to patients.

AB - CONTEXT.-: The liver is frequently affected by Epstein-Barr virus (EBV) infection, but involvement is commonly subclinical and self-limited. Severe and potentially fatal EBV hepatitis has also been occasionally reported in immunocompromised patients and, even more rarely, in immunocompetent individuals. OBJECTIVE.-: To provide a review of the clinicopathologic findings of EBV hepatitis, with a focus on microscopic features and ancillary testing with a brief discussion of the differential diagnosis. DATA SOURCES.-: Analysis of the pertinent literature (PubMed) and clinical practice experience based on institutional materials. CONCLUSIONS.-: Characteristic microscopic findings in EBV hepatitis include a diffuse lymphocytic sinusoidal infiltrate in a "string of beads" pattern, expansion of portal tracts by a predominantly lymphocytic infiltrate, and intact lobular architecture. In situ hybridization of EBV-encoded RNA is a helpful ancillary test. Correlation of clinical history, laboratory findings, and histopathologic features is essential to distinguish EBV hepatitis from autoimmune liver diseases, transplant rejection, lymphomas, and drug-induced liver injury. PMID- 30281362 TI - A Review of Smoking-Related Interstitial Fibrosis, Respiratory Bronchiolitis, and Desquamative Interstitial Pneumonia: Overlapping Histology and Confusing Terminology. AB - Smoking-related lung diseases traverse a spectrum of clinicopathologic entities, with cases often comprising a complex mixture of findings. The complexity of the diagnostic process extends beyond the histologic findings to the nomenclature, which is murky from a seemingly unending expansion of terms being applied to a handful of pathologic changes. Here, we focus our review on smoking-related interstitial fibrosis, respiratory bronchiolitis, and desquamative interstitial pneumonia, 3 entities that perhaps show the most histologic overlap and suffer from competing terminology. PMID- 30281363 TI - Approach to the Liver Biopsy in the Patient With Chronic Low-Level Aminotransferase Elevations. AB - Pathologists sometimes encounter a liver biopsy from an asymptomatic patient with unexplained low-level parenchymal liver enzyme elevations. These biopsies often have minor histologic changes but are otherwise almost entirely normal. This can lead to the quandary of whether or not the features are clinically meaningful and how one must formulate a diagnosis from the possibly nonspecific findings of a near-normal biopsy. The following discussion focuses on the histologic changes that can be seen in these biopsies and the practical issues involved in making a diagnosis that provides useful information to the clinician. The literature and textbooks addressing the histologic and clinical features of these cases are reviewed with an emphasis on the clinical implications of finding nonspecific histologic alterations in these patients. PMID- 30281364 TI - Succinate Dehydrogenase-Deficient Renal Cell Carcinoma: A Short Review. AB - Succinate dehydrogenase (SDH) is a mitochondrial enzyme complex composed of 4 protein subunits (SDHA, SDHB, SDHC, and SDHD). Germ line mutations of the genes encoding these SDH subunits result in hereditary syndromes harboring pheochromocytomas/paragangliomas, gastrointestinal stromal tumors, renal cell carcinomas, and pituitary adenomas. SDH-deficient renal cell carcinomas are rare, with a mean age of 38 to 40 years. Histologically, these tumors show a characteristic appearance that includes a solid, nested, or tubular architecture with variable cysts. Cells are typically cuboidal, have indistinct cell borders and eosinophilic cytoplasm, and show flocculent intracytoplasmic inclusions. Loss of immunohistochemical staining for SDHB is the hallmark of these tumors. Although most SDH-deficient renal cell carcinomas are clinically indolent, some tumors may behave aggressively, particularly those with a high nuclear grade, tumor necrosis, or sarcomatoid differentiation. Accurate classification of these tumors is important for clinical follow-up, screening, and genetic evaluation of the patients and other family members for this hereditary tumor syndrome. PMID- 30281365 TI - Dedifferentiated Liposarcoma With Myofibroblastic Differentiation. AB - CONTEXT.-: Liposarcoma is divided into myxoid, pleomorphic, well-differentiated, and dedifferentiated subtypes. Dedifferentiated liposarcoma displays the greatest histomorphologic diversity, including a subset with myofibroblastic differentiation that shares similarities with a spectrum of reactive, benign, and malignant soft tissue lesions. Misdiagnosis may lead to deleterious consequences, as dedifferentiated liposarcoma differs significantly in its prognosis and treatment from its mimics. OBJECTIVE.-: To review the clinicopathologic, immunohistochemical, and molecular features of the myofibroblastic variant of dedifferentiated liposarcoma as well as the key distinguishing features from its mimics. DATA SOURCES.-: Review of pertinent literature on major features and current understanding of dedifferentiated liposarcoma with myofibroblastic differentiation. CONCLUSIONS.-: The myofibroblastic variant of dedifferentiated liposarcoma is an uncommon and underrecognized sarcoma with several important differential diagnoses, and likely represents the major subset of aggressive retroperitoneal tumors that may have been misdiagnosed as desmoid-type fibromatosis, inflammatory myofibroblastic tumor, or another type of sarcoma in the past. PMID- 30281366 TI - Signet Ring Stromal Cell Tumor: A Legitimate (Benign) Mimic of Krukenberg Tumor. AB - Signet ring stromal cell tumor is a rare, benign ovarian neoplasm thought to arise from ovarian stromal cells. The pathophysiology of these tumors is poorly understood. They present in women in a wide age range, often with nonspecific symptoms including lower abdominal or pelvic pain. Their morphologic appearance raises a critical differential diagnosis of Krukenberg tumor, an aggressive malignancy with significant implications for patient management. For this reason, it is important for the pathologist to be aware of signet ring stromal cell tumor and its differentiating features, including useful histochemical and immunohistochemical ancillary tests. These tumors are curable with surgical excision, and there have been no recurrences or metastases among reported cases. PMID- 30281367 TI - Glandular Tumors of the Urachus and Urinary Bladder: A Practical Overview of a Broad Differential Diagnosis. AB - Primary glandular tumors of the urachus and urinary bladder are an intriguing group of clinically and morphologically diverse neoplasms for which there have been recent refinements in diagnostic subclassification and advances in molecular pathology. In addition, the urachus and urinary bladder may be secondarily involved by tumors with glandular differentiation that demonstrate remarkable morphologic, immunophenotypic, and molecular overlap. Thus, surgical pathologists need to be aware of the broad differential diagnosis of glandular tumors that involve the urachus and urinary bladder and have a practical diagnostic framework to evaluate these lesions in routine clinical practice. In this review, we summarize the salient clinical, morphologic, immunohistochemical, and molecular features of glandular tumors of the urachus and urinary bladder, including mucinous cystic tumors of the urachus, noncystic urachal adenocarcinomas, urothelial carcinomas with glandular or pseudoglandular features, primary urinary bladder adenocarcinomas, and Mullerian-type carcinomas, highlighting the strengths and limitations of various diagnostic features and ancillary tests, as well as the need for close clinical and radiographic correlation. PMID- 30281368 TI - Biphenotypic Sinonasal Sarcoma: A Review and Update. AB - CONTEXT.-: Biphenotypic sinonasal sarcoma (BSNS) is a rare, slow-growing soft tissue sarcoma of the sinonasal tract, typically presenting with nonspecific obstructive nasal symptoms. Although recurrences are common, no metastases have been reported, and only 1 patient has died of disease thus far. It characteristically demonstrates rearrangements of PAX3 with multiple fusion partners, the most common of which is MAML3. OBJECTIVES.-: To highlight the most important diagnostic features, including morphologic, immunohistochemical, and molecular findings, and to provide comparisons to other entities in the differential diagnosis. We also aim to provide a summary of the clinical features and outcomes in cases reported to date. DATA SOURCES.-: Recently published literature encompassing BSNS and its synonym, low-grade sinonasal sarcoma with neural and myogenic differentiation. CONCLUSIONS.-: BSNS is a sinonasal tumor that is important to recognize because its biologic behavior differs from most of the entities in the differential diagnosis. The diagnosis can typically be rendered through a combination of morphology, immunohistochemical stains, and ancillary testing for characteristic PAX3 rearrangements.

PMID- 30281370 TI - Atypical Ductal Lesions of the Breast: Criteria, Significance, and Laboratory Updates. AB - CONTEXT.-: Atypical ductal hyperplasia (ADH) is a challenging diagnosis defined by cytologic and architectural features that carries an increased risk of subsequent carcinoma when diagnosed in isolation. In addition, ADH may secondarily involve benign breast lesions, wherein it carries variable clinical significance. OBJECTIVES.-: To review the diagnostic criteria and clinical significance of ADH in isolation and as it involves benign breast lesions, and to review the evolving literature on its molecular signature. DATA SOURCES.-: Recently published studies that collectively examine ADH were reviewed. CONCLUSIONS.-: Atypical ductal hyperplasia carries an increased risk of subsequent carcinoma in isolation and when it involves most benign breast lesions. Identifying which cases of ADH will be upgraded to carcinoma has been challenging, and new laboratory developments, such as EZH2 overexpression, may have a future role. PMID- 30281371 TI - Hereditary Leiomyomatosis and Renal Cell Carcinoma Syndrome (HLRCC): A Contemporary Review and Practical Discussion of the Differential Diagnosis for HLRCC-Associated Renal Cell Carcinoma. AB - CONTEXT.-: Hereditary leiomyomatosis and renal cell carcinoma syndrome (HLRCC) is an uncommon disorder with germline-inactivating mutations in the fumarate hydratase ( FH) gene. The kidney cancers that develop in patients with HLRCC are often unilateral and solitary, with a potentially aggressive clinical course; morphologic identification of suspicious cases is of the utmost importance. OBJECTIVE.-: To review classic morphologic features of HLRCC-associated renal cell carcinoma, the reported morphologic spectrum of these tumors and their mimics, and the evidence for use of immunohistochemistry and molecular testing in diagnosis of these tumors. DATA SOURCES.-: University of Michigan cases and review of pertinent literature about HLRCC and the morphologic spectrum of HLRCC associated renal cell carcinoma. CONCLUSIONS.-: Histologic features, such as prominent nucleoli with perinucleolar halos and multiple architectural patterns within one tumor, are suggestive of HLRCC-associated renal cell carcinoma. However, the morphologic spectrum is broad. Appropriate use of FH immunohistochemistry and referral to genetic counseling is important for detection of this syndrome.

PMID- 30281373 TI - Lenticule Thickness Accuracy and Influence in Predictability and Stability for Different Refractive Errors after SMILE in Chinese Myopic Eyes. AB - PURPOSE: To evaluate the differences between the estimated and measured lenticule thickness and relationships in myopic eyes with different refractive errors after small-incision lenticule extraction (SMILE). METHODS: This prospective study included a total of 190 eyes (96 patients) with a manifest refraction spherical equivalent (MRSE) of -6.16 +/- 1.71 D. The measured lenticule thickness was obtained from digital spectral-domain optical coherence tomography image analysis. The estimated lenticule thickness was obtained from the software program. Comparative statistics and linear regression analyses were performed. RESULTS: At 1 month, the estimated lenticule thickness was 113.68 +/- 19.35 um and the measured lenticule thickness was 96.9 +/- 17.5 um. The difference between the estimated and measured lenticule thickness was 13.63 +/- 9.1 um (p < 0.001) thicker. The difference was lower than the mean data in the moderate myopia group (9.7 +/- 6.4 um) and larger in the high myopia group (12.3 +/- 8.8 um) and the super-high myopia group (17.9 +/- 6.9 um). The discrepancy between the estimated and measured lenticule thickness was significantly dependent on the MRSE (p < 0.001). MRSE only showed significant differences between the three and six-month follow-up visit in the super-high myopic group (p = 0.03). CONCLUSION: The measured lenticule thickness was thinner than the estimated lenticule thickness for SMILE in most eyes. The higher the refraction, the larger the difference after SMILE surgery. The mismatch between the estimated and measured thickness did not influence the refractive precision and stability of different refractive errors. PMID- 30281374 TI - Photodynamic therapy on skin melanoma and epidermoid carcinoma cells using conjugated 5-aminolevulinic acid with microbial synthesised silver nanoparticles. AB - The present research work describes the use of photodynamic therapy (PDT) of drug 5-aminolevulinic acid (5-ALA) conjugated with microbial synthesised silver nanoparticles on skin melanoma (B16F10) and epidermoid carcinoma (A431) cell lines. Silver nanoparticles were synthesised using the bacterial strain Bacillus licheniformis. The morphology of the nanoparticles was studied using scanning electron microscopy (SEM) and elemental analysis of nanoparticles was carried out using energy dispersive X-ray spectroscopy (EDX). Fourier-transform infrared spectroscopy (FTIR) analysis was performed to assess the functional groups of the nanoparticles. Crystalline nature of nanoparticles was assessed using powder X ray diffraction (XRD).The cytotoxicity of pure nanoparticles and conjugated nanoparticles with 5-ALA using polyethylene glycol (PEG) was assessed on B16F10 and A431 cell lines and also compared with standard 5-ALA. Production of ROS molecules was measured using a 2,7-dichlorofluorescein-diacetate (DCFH-DA) probe. The results showed that the 5-ALA-silver nanoparticles conjugate had higher cytotoxicity on both the cell lines than the pure ALA and silver nanoparticles. Antimicrobial activity of silver nanoparticles was also carried out on food borne pathogens and nanoparticles showed comparable antimicrobial activity with standard antibiotics. PMID- 30281375 TI - Early Detection of Ovarian Dysfunction by Anti-Mullerian Hormone in Adolescent and Young Adult-Aged Survivors of Childhood Cancer. AB - PURPOSE: Current guidelines recommend screening at-risk childhood cancer survivors for ovarian dysfunction using follicle-stimulating hormone (FSH). However, FSH identifies diminished ovarian reserve (DOR), a component of ovarian dysfunction, in the later stages when fertility preservation is less likely to succeed. This analysis evaluates the utility of anti-Mullerian hormone (AMH) for the assessment of DOR in adolescent and young adult (AYA)-aged survivors of childhood cancer. METHODS: A retrospective chart review of 13- to 21-year-old female survivors who received gonadotoxic therapy and were >=2 years off therapy was performed. Gonadotoxic treatments were categorized as low, moderate, or high risk for future infertility. Patients with AMH below the assay's age-specific normal range were identified and stratified by FSH values (normal <=12 mIU/mL). Prevalence of low AMH and AMH-FSH subgroups was calculated and risk factors were evaluated using logistic regression. RESULTS: AMH was measured in 190 survivors who received gonadotoxic treatment; of them, 35.3% had low AMH. Among survivors who received <30 Gy cranial radiation and were not on hormone therapy (n = 141), 18.4% had normal FSH with low AMH. Stratified by future infertility risk, 10.6% of low-risk, 38.1% of moderate-risk, and 25.7% of high-risk survivors had normal FSH with low AMH (p < 0.01). Within the low-risk group, normal FSH with low AMH was significantly associated with older age at diagnosis (p = 0.02). CONCLUSION: Nearly 20% of AYA-aged at-risk survivors had low AMH and normal FSH. DOR in these patients would have been missed in standard recommended surveillance practices. PMID- 30281376 TI - The Effects of Bilateral Priming on Motor Cortex Function in Healthy Adults. AB - Bilateral priming is a rehabilitation adjuvant that can improve upper limb motor recovery post-stroke. It uses a table-top device to couple the upper limbs together such that active flexion and extension of one wrist leads to passive movement of the opposite wrist in a mirror symmetric pattern. Bilateral priming increases corticomotor excitability (CME) in the primary motor cortex (M1) of the passively driven wrist, however the neurophysiological mechanisms underlying this increase remain unclear. This study explored these mechanisms by using transcranial magnetic stimulation over the right M1 and recording motor evoked potentials from the passively driven left extensor carpi radialis of healthy adults. Intracortical measures were recorded before and five and 35 minutes after a single 15-minute session of priming. 1 ms short-interval intracortical inhibition, long-interval intracortical inhibition, late cortical disinhibition (LCD) and intracortical facilitation were recorded with a posterior-anterior (PA) intracortical current, while CME and short-interval intracortical facilitation (SICF) were recorded with both PA and anterior-posterior (AP) currents. CME with PA stimulation was also recorded approximately one hour post-priming. PA CME was elevated 35 minutes post-priming and remained elevated approximately one hour post-priming. LCD decreased and AP SICF increased at both 5 and 35 minutes post priming. However, these changes in LCD and AP SICF are unlikely to be the cause of the increased PA CME due to the differing timelines of their effects and AP and PA currents activating separate interneuron circuits. These results suggest bilateral priming does not increase CME through alterations of the intracortical circuits investigated here. PMID- 30281377 TI - Safety and effectiveness of istradefylline in patients with Parkinson's disease: interim analysis of a post-marketing surveillance study in Japan. AB - BACKGROUND: Istradefylline is a first-in-class, non-dopaminergic, selective adenosine A2A receptor antagonist for the treatment of Parkinson's disease (PD) in patients experiencing the wearing-off phenomenon with levodopa (L-DOPA). The authors present an interim report from a post-marketing surveillance (PMS) evaluating the safety and effectiveness of long-term istradefylline in a real world setting. RESEARCH DESIGN AND METHODS: Istradefylline safety was assessed by the incidence of adverse events (AE) and adverse drug reactions (ADRs). Effectiveness was assessed using the physician's assessment of off-time, off-time symptoms and motor dysfunction, unified PD rating scale (UPDRS) Part III score, and the physician's global assessment. RESULTS: This analysis evaluated 476 patients. Istradefylline was generally well tolerated, despite dyskinesia and hallucination being the most common ADRs. Reduction in off-time was observed in 38.2% of patients, off-time symptoms were improved or markedly improved in 44.7%, and motor dysfunction was improved or markedly improved in 48.5%. The mean UPDRS Part III score decreased from 33.7 to 30.3 at the end of the study. The physician's global assessment rated the drug as effective in 61.3% of patients. CONCLUSIONS: This PMS provides useful safety and effectiveness data for long-term treatment with istradefylline in a real-world setting for patients with PD exhibiting the wearing-off phenomenon with L-DOPA. PMID- 30281378 TI - Axillary Lymph Node Dissection for Breast Cancer: Efficacy and Complication in Developing Countries. AB - PURPOSE: Axillary lymph node dissection (ALND) frequently is performed as part of the surgical management of breast cancer as a therapeutic and prognostic index, but increasingly has been perceived as associated with significant complications. Data on efficacy and complications of ALND in Sudan are lacking. The aim of this study was to assess the efficacy and complications of ALND in patients with breast cancer treated with mastectomy and breast-conserving surgery. METHODS: We performed a prospective, hospital-based study in women with invasive breast cancer who underwent modified radical mastectomy or breast-conserving surgery with ALND between September 2014 and August 2015. The efficacy of ALND was defined as retrieval of >= 10 lymph nodes. Complications of ALND were assessed objectively and subjectively and defined as either present or absent. RESULTS: Of 96 patients with breast cancer included in the study, 40 (42%) developed postaxillary clearance complications. The median follow-up time was 18 months (range, 12 to 24 months). Numbness was reported by 21.9% of patients. Seroma was noted in 15.6% and lymphedema in 9.4%. Approximately 9% reported episodes of infection or inflammation at the surgical site. None of the studied factors were found to affect the incidence of complications significantly. Ten or more lymph nodes were retrieved in 81.3% of patients, and nodal metastasis was found in 62.5%. CONCLUSION: This study shows that the prevalence of undesirable adverse effects after ALND is 42%, with paresthesia and seroma being the most prevalent. The lymphedema prevalence was low in relation to other evaluated symptoms. PMID- 30281379 TI - Cdt1 variants reveal unanticipated aspects of interactions with Cyclin/CDK and MCM important for normal genome replication. AB - The earliest step in DNA replication is origin licensing which is the DNA loading of MCM helicase complexes. The Cdt1 protein is essential for MCM loading during G1 phase of the cell cycle, yet the mechanism of Cdt1 function is still incompletely understood. We examined a collection of rare Cdt1 variants that cause a form of primordial dwarfism (Meier-Gorlin syndrome) plus one hypomorphic Drosophila allele to shed light on Cdt1 function. Three hypomorphic variants load MCM less efficiently than WT Cdt1, and their lower activity correlates with impaired MCM binding. A structural homology model of the human Cdt1-MCM complex position the altered Cdt1 residues at two distinct interfaces rather than the previously described single MCM interaction domain. Surprisingly, one dwarfism allele ( Cdt1-A66T) is more active than WT Cdt1. This hypermorphic variant binds both Cyclin A and SCFSkp2 poorly relative to WT Cdt1. Detailed quantitative live cell imaging analysis demonstrated no change in stability of this variant however. Instead, we propose that Cyclin A/CDK inhibits Cdt1 licensing function independently of the creation of the SCFSkp2 phosphodegron. Together, these findings identify key Cdt1 interactions required for both efficient origin licensing and tight Cdt1 regulation to ensure normal cell proliferation and genome stability. PMID- 30281380 TI - Anticipatory Postural Adjustments and Spatial Organization of Motor Cortex - Evidence of Adaptive Compensations in Healthy Older Adults. AB - During anticipated postural perturbations induced by limb movement, the central nervous system generates anticipatory postural adjustments (APAs) in the trunk and hip musculature to minimize disturbances to equilibrium. Age-related changes in functional organization of the nervous system may contribute to changes in APAs in older adults. Here we examined if altered APAs of trunk/hip musculature in older adults are accompanied by changes in the representation of these muscles in motor cortex. 12 healthy older adults, 5 with a history of falls and 7 non fallers, were compared to 13 young adults. APAs were assessed during a mediolateral arm raise task in standing. Temporal organization of postural adjustments was quantified as latency of APAs in the contralateral external oblique, lumbar paraspinals and gluteus medius relative to activation of the deltoid. Spatial organization was quantified as extent of synergistic coactivation between muscles. Volume and location of the muscle representations in motor cortex were mapped using transcranial magnetic stimulation. We found that older adults demonstrated significantly delayed APAs in the gluteus medius. Spatial organization of the muscles in motor cortex differed between groups, with the older adults demonstrating more lateral external oblique representation than the other two muscles. Separate comparisons of the fallers and non-fallers with young adults indicated that non-fallers had the greatest delay in gluteus medius APAs and a reduced distance between the representational areas of the lumbar paraspinals and gluteus medius. This study indicates that altered spatial organization of motor cortex accompanies altered temporal organization of APA synergies in older adults. PMID- 30281381 TI - The Effectiveness of Intermittent Pneumatic Compression in Therapy of Lymphedema of Lower Limbs: Methods of Evaluation and Results. AB - BACKGROUND: Evaluation of intermittent pneumatic compression (IPC) in lymphedema is classically based on measurements of circumferences and volume of the edematous limb. However, although important, it provides only a general information without insight into what proceeds under the skin with respect to hydromechanical and structural changes. AIM AND METHODS: We present the multimodal evaluation of the effectiveness of IPC device in limb edema by measuring tissue stiffness, fluid pressure, and flow volume, and lymphoscintigraphic and near-infrared fluorescence (NIRF) indocyanine green (ICG) lymphography imaging of edema fluid movement, before and after one 45-60 minute compression cycle in over 50 patients with lymphedema stage II and III. RESULTS: (1) Tissue fluid pressures were lower than those applied by IPC device. (2) The higher the applied compression force, the larger the flow volume. (3) Skin stiffness (superficial tonometry) decreased mainly in the calf, whereas, subcutaneous tissue (deep tonometry) was observed at all limb levels. (4) Skin water concentration (dielectric constant) was only insignificantly decreased, but subcutaneous extracellular water (bioimpedance Ldex index, fluid movement force test) was effectively moved away to limb proximal regions. (5) Imaging tissue (edema) fluid flow pathways on lymphoscintigram and real-time flow on NIRF ICG video could be observed and were evaluated semiquantitatively. CONCLUSIONS: Adjustment of compression parameters to tissue stiffness, fluid accumulation volumes, and fluid movement ability (hydraulic conductivity of tissues) at various limb levels is indispensable for effective therapy. Redesigning of compression devices will be needed to enable applying differentiated compression pressures and prolonged timings at various limb levels. PMID- 30281382 TI - Validity and Reliability of Three-Dimensional Imaging for Measuring Breast Cancer Related Lymphedema in the Upper Limb: A Cross-Sectional Study. AB - BACKGROUND: In the past, measurement of upper limb lymphedema was done by water displacement (WD), which is frequently cited as the gold standard. For various reasons, however, the use of WD is restricted in clinical settings. A more precise and easy-to-use method would be favorable. The high precision of three dimensional (3D) imaging in comparison to WD has already been reported for healthy subjects. The aim of this study is to determine the validity and reliability of 3D imaging by comparing it to the WD method in women with unilateral upper limb lymphedema. METHODS AND RESULTS: Thirty-nine women with unilateral breast cancer-related lymphedema (BCRL) were included, of which 37 completed two volume measurement techniques (3D and WD) on the BCRL and contralateral healthy arm. Slightly larger volumes were measured by the WD method in healthy arms (+9.8 mL; p = 0.058) and also in BCRL arms (+18.5 mL; p < 0.001). All measurements were performed twice by the same researcher to evaluate reliability. There was no significant difference between the two measurements for healthy arms (p = 0.323) or BCRL arms (p = 0.807) in 3D imaging. Bland-Altman plots showed a high limit of agreement between the single measurements. 3D imaging had a high intrarater reliability (Intraclass Correlation Coefficient = 0.999). CONCLUSION: Results show that 3D imaging is an innovative method for measuring upper limb volume in BCRL patients. Even though image processing is time consuming, 3D imaging combines high reproducibility with high precision. By software automation, this technique could easily be integrated into clinical routine. It is for this reason that we would recommend implementing the Vectra 3D imaging technique for measurement of BCRL. PMID- 30281383 TI - 80 Years Old, and Never Looked Better: Rebranding in 2019. PMID- 30281384 TI - Complex Decongestive Therapy in Breast Cancer-Related Lymphedema: Does Obesity Affect the Outcome Negatively? AB - BACKGROUND: The aim of this prospective clinical study was to compare the long term efficacy of complex decongestive therapy (CDT) in obese and nonobese patients with breast cancer-related lymphedema (BCRL). MATERIALS AND METHODS: A total of 59 patients (29 obese patients group 1, 30 normoweight overweight patients group 2) with unilateral BCRL were enrolled. All patients underwent CDT that included manual lymphatic drainage, intermittent pneumatic compression pump, multilayer compression bandaging, lymphedema exercises, and skin care. The CDT was performed for 1 hour a day, 5 days a week for 3 weeks. Patients were assessed according to limb volume difference before CDT, after CDT, and after 1 year. RESULTS: The initial lymphedema volume of group 1 was 866.34 +/- 389.34 mL and that of group 2 was 661.84 +/- 470.6 mL (p = 0.031). The lymphedema severity percentage of excess volume (PEV) of group 1 was 33.37 +/- 15.71 and that of group 2 was 31.86 +/- 19.63, which was moderate lymphedema. After 15 sessions of CDT program, in group 1, lymphedema volume decreased to 771.46 +/- 389.14 mL (post-CDT p = 0.013) and in group 2, lymphedema volume decreased to 468.38 +/- 417.36 mL (post-CDT p < 0.0001), and in group 1, PEV decreased to 28.54 +/- 16.84 (post-CDT p = 0.002) and that in group 2 decreased to 22.1 +/- 16.87 (post-CDT p < 0.0001). After 1 year, group 1 reached the baseline values of the extremity volumes, but in group 2, the volumes of extremities could maintain their post-CDT values. CONCLUSION: Obesity is a factor that deteriorates the CDT efficacy. Early treatment, before developing fat accumulation and fibrosis, must be primary goal in the treatment of BCRL. PMID- 30281385 TI - Highly Synergistic Effects of Melittin with Conventional Antibiotics Against Multidrug-Resistant Isolates of Acinetobacter baumannii and Pseudomonas aeruginosa. AB - BACKGROUND: Morbidity and mortality due to multidrug-resistant (MDR) bacteria are of great concern in burn patients. In this critical condition, synergism between antimicrobial peptides and conventional antibiotics would be a promising strategy. Accordingly, this study aimed to determine the therapeutic value of melittin as a natural peptide by examining its synergistic effect with conventional antibiotics against MDR isolates of Acinetobacter baumannii and Pseudomonas aeruginosa. MATERIALS AND METHODS: Fifteen clinical isolates for each kind of bacteria were collected from burn patients. Antibiotic susceptibility of all isolates was evaluated by disk diffusion method. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration for melittin, colistin, doripenem, doxycycline, and ceftazidime were also examined. Fractional inhibitory concentration (FIC) of melittin in combination with the antibiotics was determined for six MDR isolates. The cytotoxicity of melittin in combination with the antibiotics was examined on a normal human cell line. RESULTS: The geometric means of MIC (GMMIC) for melittin and doripenem after combination were reduced to 61.5- and 51.5-fold, respectively, against MDR A. baumannii isolates. These reductions for melittin-doripenem and melittin-ceftazidime against MDR P. aeruginosa isolates were (63.5 and 58)-fold and (16 and 11)-fold, respectively. FIC for melittin-doripenem against A. baumannii and FIC for melittin-doripenem and melittin-ceftazidime against P. aeruginosa strains were <=0.5. This issue caused a decrease of up to 104-, 68-, and 17-fold, respectively, in the cytotoxicity of melittin. CONCLUSION: In conclusion, the synergism of melittin at its nontoxic dose with doripenem and ceftazidime could be of great therapeutic value as a topical drug against burn infections caused by MDR bacteria. PMID- 30281386 TI - Organ of Corti vibration within the intact gerbil cochlea measured by volumetric optical coherence tomography and vibrometry. AB - There is indirect evidence that the mammalian cochlea in the low-frequency apical and the more commonly-studied high-frequency basal regions function in fundamentally different ways. Here, we directly tested this hypothesis by measuring sound-induced vibrations of the organ of Corti (OoC) at three turns of the gerbil cochlea using volumetric optical coherence tomography vibrometry (VOCTV), an approach that permits non-invasive imaging through the bone. In the apical turn, there was little frequency selectivity and the displacement-versus frequency curves had low-pass filter characteristics with a corner frequency of ~0.5-0.9 kHz. The vibratory magnitudes increased compressively with increasing stimulus intensity at all frequencies. In the middle turn, responses were similar except for a slight peak in the response at ~2.5 kHz. The gain was ~ 50 dB at the peak and 30-40 dB at lower frequencies. In the basal turn, responses were sharply tuned and compressively nonlinear, consistent with observations in the literature. These data demonstrated that there is a transition of the mechanical response of the OoC along the length of the cochlea such that frequency tuning is sharper in the base than in the apex. Since the responses are fundamentally different, it is not appropriate to simply frequency shift vibratory data measured at one cochlear location to predict the cochlear responses at other locations. Furthermore, this means that the number of hair cells stimulated by sound is larger for low-frequency stimuli and smaller for high-frequency stimuli for the same intensity level. Thus, the mechanisms of central processing of sounds must vary with frequency. PMID- 30281388 TI - Synergies in coordination: a comprehensive overview of neural, computational and behavioral approaches. AB - At face value, the term 'synergy' provides a unifying concept within a fractured field that encompasses complementary neural, computational and behavioral approaches. However, the term is not used synonymously by different researchers, but has substantially different meanings depending on the research approach. With so many operational definitions for the one term, it becomes difficult to use as either a descriptive or explanatory concept, yet it remains pervasive and apparently indispensable. Here we provide a summary of different approaches that invoke 'synergies' in a descriptive or explanatory context, summarizing progress, not within the one approach, but across the theoretical landscape. Bernstein's framework of flexible hierarchical control may provide a unifying framework here, since it can incorporate divergent ideas about synergies. In the current motor control literature, 'synergy' may refer to conceptually different processes that could potentially operate in parallel, across different levels within the same hierarchical control scheme. There is evidence for the concurrent existence of synergies with different features, both 'hard-wired' and 'soft-wired', task independent and task-dependent. By providing a comprehensive overview of the multifaceted ideas about synergies, our goal is to move away from the compartmentalization and narrow focus on one level and promote a broader perspective on the control and coordination of movement.

PMID- 30281390 TI - Choanoflagellate transfection illuminates their cell biology and the ancestry of animal septins. AB - As the closest living relatives of animals, choanoflagellates offer unique insights into animal origins and core mechanisms underlying animal cell biology. However, unlike traditional model organisms, such as yeast, flies and worms, choanoflagellates have been refractory to DNA delivery methods for expressing foreign genes. Here we report the establishment of a robust method for expressing transgenes in the choanoflagellate Salpingoeca rosetta, overcoming barriers that have previously hampered DNA delivery and expression. To demonstrate how this method accelerates the study of S. rosetta cell biology, we engineered a panel of fluorescent protein markers that illuminate key features of choanoflagellate cells. We then investigated the localization of choanoflagellate septins, a family of GTP-binding cytoskeletal proteins that are hypothesized to regulate multicellular rosette development in S. rosetta. Fluorescently tagged septins localized to the basal pole of S. rosetta single cells and rosettes in a pattern resembling septin localization in animal epithelia. The establishment of transfection in S. rosetta and its application to the study of septins represent critical advances in the growth of S. rosetta as an experimental model for investigating choanoflagellate cell biology, core mechanisms underlying animal cell biology, and the origin of animals. PMID- 30281391 TI - Application of the fluctuation theorem for non-invasive force measurement in living neuronal axons. AB - Although its importance is recently widely accepted, force measurement has been difficult in living biological systems, mainly due to the lack of the versatile non-invasive force measurement methods. The fluctuation theorem, which represents the thermodynamic properties of small fluctuating non-equilibrium systems, has been applied to the analysis of the thermodynamic properties of motor proteins in vitro. Here, we extend it to the axonal transport (displacement) of endosomes. The distribution of the displacement fluctuation had three or four distinct peaks around multiples of a unit value, which the fluctuation theorem can convert into the drag force exerted on the endosomes. The results demonstrated that a single cargo vesicle is conveyed by one to three or four units of force production. PMID- 30281392 TI - Advancing Freund's and AddaVax Adjuvant Regimens Using CpG Oligodeoxynucleotides. AB - Adjuvant can play an important role in vaccine formulation by aiding in the development of a robust immune response. In our hybridoma development work, we typically use both Freund's and AddaVaxTM adjuvant regimens for mouse immunizations. While we have repeatedly shown success with our protocols, we continually seek to improve upon the titer and affinity of the serum antibody response. To that end, we evaluated the use of CpG oligodeoxynucleotides (CpG DNA), a B cell stimulant, in our adjuvant regimens. Mice were immunized using our standard Freund's protocol (Adjulite Complete Freund's Adjuvant for the primary immunization followed by Adjulite Incomplete Freund's Adjuvant (AIFA) for all additional immunizations) or a test protocol using AIFA supplemented with CpG-DNA for all immunizations. A second group of mice were immunized with antigen emulsified in AddaVax adjuvant alone or AddaVax supplemented with CpG-DNA. Our results show a trend toward a higher titer response when CpG-DNA was used with either adjuvant. In addition, AIFA+CpG-DNA mice trended toward a higher relative affinity versus mice immunized using our standard Freund's methodology. Additional antigens will need to be studied to determine whether these observations are limited to the proteins (antigens) studied or whether this is a generalized response to any immunogen. PMID- 30281393 TI - Phage-displayed peptides targeting specific tissues and organs. AB - Phage display is a powerful and widely used technique to find novel peptide ligands. A massive amount of peptide sequences have been identified for all kinds of materials, and peptides that may have targeting capabilities towards specific cells and tissues have received special attention in biomedical sciences. As a result, it is increasingly harder to follow all the work that has been done, which sometimes leads to many promising ligands receiving little attention, together with the publication of false positives that have already been found. The aim of this review is to provide an updated and comprehensive list of phage displayed peptides targeting different tissues and organs. The limitations of the technique are carefully analysed and the future perspectives envisaged. PMID- 30281394 TI - Depletion of SMC5/6 sensitizes male germ cells to DNA damage. AB - The structural maintenance of chromosomes complex, SMC5/6, is thought to be essential for DNA repair and chromosome segregation during mitosis and meiosis. To determine the requirements of the SMC5/6 complex during mouse spermatogenesis we combined a conditional knockout allele for Smc5, with four germ cell specific Cre recombinase transgenes, Ddx4-Cre, Stra8-Cre, Spo11-Cre and Hspa2-Cre, to mutate Smc5 in spermatogonia, in spermatocytes prior to meiotic entry, during early meiotic stages, and during mid-meiotic stages, respectively. Conditional mutation of Smc5 resulted in destabilization of the SMC5/6 complex. Despite this, we observed only mild defects in spermatogenesis. Mutation of Smc5 mediated by Ddx4-Cre and Stra8-Cre resulted in partial loss of pre-leptotene spermatocytes; however, spermatogenesis progresses and mice are fertile. Mutation of Smc5 via Spo11-Cre or Hspa2-Cre did not result in detectable defects of spermatogenesis. Upon exposure to gamma irradiation or etoposide treatment, each conditional Smc5 mutant demonstrated an increase in enlarged round spermatids with multiple acrosomes and supernumerary chromosome content. We propose that the SMC5/6 complex is not acutely required for pre-meiotic DNA replication and meiotic progression during mouse spermatogenesis; however, when germ cells are challenged by exogenous DNA damage, the SMC5/6 complex ensures genome integrity, and thus, fertility. PMID- 30281395 TI - Serotonin regulates the dynamics of cerebellar granule cell activity by modulating tonic inhibition. AB - Understanding how afferent information is integrated by cortical structures requires identifying the factors shaping excitation and inhibition within their input layers. The input layer of the cerebellar cortex integrates diverse sensorimotor information to enable learned associations that refine the dynamics of movement. Specifically, mossy fiber afferents relay sensorimotor input into the cerebellum to excite granule cells, whose activity is regulated by inhibitory Golgi cells. To test how this integration can be modulated, we have used an acute brain slice preparation from young adult rats and found that encoding of mossy fiber input in the cerebellar granule cell layer can be regulated by serotonin (5 HT) via a specific action on Golgi cells. We find that 5-HT depolarizes Golgi cells, likely by activating 5-HT2A receptors, but does not directly act on either granule cells or mossy fibers. As a result of Golgi cell depolarization, 5-HT significantly increases tonic inhibition onto both granule cells and Golgi cells. 5-HT-mediated Golgi cell depolarization is not sufficient, however, to alter the probability or timing of mossy fiber-evoked feed-forward inhibition onto granule cells. Together, increased granule cell tonic inhibition paired with normal feed forward inhibition acts to reduce granule cell spike probability without altering spike timing. These data hence provide a circuit mechanism by which 5-HT can reduce granule cell activity without altering temporal representations of mossy fiber input. Such changes in network integration could enable flexible, state specific suppression of cerebellar sensorimotor input that should not be learned, or enable reversal learning for unwanted associations. PMID- 30281397 TI - Comparison of rate of tooth movement and pain perception during accelerated tooth movement associated with conventional fixed appliances with micro osteoperforations - a randomised controlled trial. AB - OBJECTIVES: To investigate the influence of micro-osteoperforation (MOP) on rate of orthodontic tooth movement and pain perception with fixed appliances. DESIGN: 2 arm parallel randomized controlled trial with an allocation ratio of 1:1. SETTING: The outpatient department of a dental college. PARTICIPANTS: 105 patients were screened, out of which 60 met the inclusion criteria and consented to participate; consisting of 33 females and 27 males requiring en-masse retraction following first premolar extractions. METHODS: The experimental group consisted of patients bonded with a fixed appliance (Gemini 3M) who received MOP distal to canines throughout the period of retraction every 28 days. These were compared with a control group treated with identical brackets without MOP and were assessed for rate of tooth movement (canine retraction) and pain perception using a Visual Analogue Scale (VAS) of 10 mm. RESULTS: Prior to commencement, all baseline parameters were matched between the two groups (p>0.05). A statistically significant increase in rate of tooth movement in the MOP group (p<0.05). CONCLUSION: MOP appears to enhance the rate of tooth movement with no differences in pain perception. PMID- 30281396 TI - Cancer-Related Cognitive Outcomes Among Older Breast Cancer Survivors in the Thinking and Living With Cancer Study. AB - PURPOSE: To determine treatment and aging-related effects on longitudinal cognitive function in older breast cancer survivors. METHODS: Newly diagnosed nonmetastatic breast cancer survivors (n = 344) and matched controls without cancer (n = 347) 60 years of age and older without dementia or neurologic disease were recruited between August 2010 and December 2015. Data collection occurred during presystemic treatment/control enrollment and at 12 and 24 months through biospecimens; surveys; self-reported Functional Assessment of Cancer Therapy Cognitive Function; and neuropsychological tests that measured attention, processing speed, and executive function (APE) and learning and memory (LM). Linear mixed-effects models tested two-way interactions of treatment group (control, chemotherapy with or without hormonal therapy, and hormonal therapy) and time and explored three-way interactions of ApoE (epsilon4+ v not) by group by time; covariates included baseline age, frailty, race, and cognitive reserve. RESULTS: Survivors and controls were 60 to 98 years of age, were well educated, and had similar baseline cognitive scores. Treatment was related to longitudinal cognition scores, with survivors who received chemotherapy having increasingly worse APE scores ( P = .05) and those initiating hormonal therapy having lower LM scores at 12 months ( P = .03) than other groups. These group-by-time differences varied by ApoE genotype, where only epsilon4+ survivors receiving hormone therapy had short-term decreases in adjusted LM scores (three-way interaction P = .03). For APE, the three-way interaction was not significant ( P = .14), but scores were significantly lower for epsilon4+ survivors exposed to chemotherapy (-0.40; 95% CI, -0.79 to -0.01) at 24 months than epsilon4+ controls (0.01; 95% CI, 0.16 to 0.18; P < .05). Increasing age was associated with lower baseline scores on all cognitive measures ( P < .001); frailty was associated with baseline APE and self-reported decline ( P < .001). CONCLUSION: Breast cancer systemic treatment and aging-related phenotypes and genotypes are associated with longitudinal decreases in cognitive function scores in older survivors. These data could inform treatment decision making and survivorship care planning. PMID- 30281399 TI - A Call for Articles: Internet of Things, Artificial Intelligence, Sensors and Omics Convergence. PMID- 30281398 TI - Effervescent-assisted dispersive liquid-liquid microextraction based on the solidification of floating organic droplets for the determination of fungicides in vinegar and juice. AB - A method of effervescent-assisted dispersive liquid-liquid microextraction based on the solidification of a floating organic droplet is reported. This approach was used to measure the fungicides myclobutanil, tebuconazole and epoxiconazole in vinegar and juice. Acidic vinegar and juice reacted with the carbonate to produce effervescence in situ, which then promoted contact of the sample with the extraction solvent. The 1-dodecanol extraction solvent helped solidify the floating organic droplets and could be fully dispersed by effervescence. The extraction solvent, salt, carbonate, and extraction time were optimised. The optimal conditions were 200 MUL of 1-dodecanol, 100 mg of sodium chloride, 50 mg of sodium bicarbonate, and 30 s of extraction time. The proposed method has good linearity between 10 and 1000 ng mL-1. Recoveries were between 70.4% and 103.1% in different vinegar and juice samples. This method was successfully used to measure fungicides in vinegar and juice. This system is simple, fast and environmentally friendly. PMID- 30281400 TI - A review of dietary exposure and toxicological information on epoxidised soybean oil (ESBO) in food-contact applications. AB - Plasticisers have a long history of use in the industrial manufacture and processing of polymers for the purpose of increasing the flexibility and strength of the material. Approximately, 80-90% of the plasticiser market is devoted to the production of PVC, a highly versatile thermoplastic used to produce both rigid and flexible articles. Many types of plasticisers, including ortho phthalate esters (OPE), can be added to PVC to impart flexibility. Recently, alternatives to OPEs, such as epoxy esters and aliphatic adipates, are becoming more prevalent for use in PVC-based food-contact articles. Epoxidised soybean oil (ESBO) is used as a plasticiser in flexible PVC for many food-contact articles, including food packaging and food processing equipment, from which it can potentially migrate into food and become a component of an individual's daily diet. The purpose of this review is to provide an update on the US dietary exposure and toxicological information on ESBO used in PVC-based food-contact articles. The cumulative dietary concentration (CDC) and cumulative estimated daily intake (CEDI) for ESBO from its use as a plasticiser in PVC-based food contact articles (i.e. gaskets for glass jar lids and film wraps) was calculated to be 2.6 mg/kg (i.e. ppm) and 0.13 mg/kg bw/d, respectively, for the general population. Some regulatory agencies have reported safety levels for ESBO, and the most conservative no observed adverse effect level (NOAEL) was identified to be 100 mg/kg bw/d (i.e. 2000 ppm) based on a two-year feeding study in rats. The current CEDI is well below these levels, supporting the safe use of ESBO in food contact applications. PMID- 30281401 TI - Elite Handcycling: A Qualitative Analysis of Recumbent Handbike Configuration for Optimal Sports Performance. AB - Our understanding of handbike configuration is limited, yet it can be a key determinant of performance in handcycling. This study explored how fourteen handcycling experts (elite handcyclists, coaches, support staff and manufacturers) perceived aspects of recumbent handbike configuration to impact upon endurance performance via semi-structured interviews. Optimising the handbike for comfort, stability and power production were identified as key themes. Comfort and stability were identified to be the foundations of endurance performance and were primarily influenced by the seat, backrest, headrest and their associated padding. Power production was determined by the relationship between the athletes' shoulder and abdomen and the trajectories of the handgrips, which were determined by the crank axis position, crank arm length and handgrip width. Future studies should focus on quantifying the configuration of recumbent handbikes before determining the effects that crank arm length, handgrip width and crank position have on endurance performance. Practitioner Summary: To gain a greater understanding of the impact of handbike configurations on endurance performance the perceptions of expert handcyclists were explored qualitatively. Optimising the handbike for comfort and stability, primarily via backrest padding, and power production, the position of the shoulders relative to handgrips and crank axis, were critical. PMID- 30281402 TI - Dear Abby: Should I Give Advice or Receive It? AB - Typically, individuals struggling with goal achievement seek advice. However, in the present investigation ( N = 2,274), struggling individuals were more motivated by giving advice than receiving it. In a randomized, controlled, double blind field experiment, middle-school students who gave motivational advice to younger students spent more time on homework over the following month than students who received motivational advice from expert teachers (Experiment 1). This phenomenon was replicated across self-regulatory domains: Strugglers who gave advice, compared with those who received expert advice, were more motivated to save money, control their tempers, lose weight, and seek employment (Experiments 2 and 3). Nevertheless, across domains, people erroneously predicted the opposite, expecting themselves and others to be less motivated by giving advice than receiving it (Experiments 2 and 3). Why are people blind to the motivational power of giving? Giving advice motivated givers by raising their confidence-a reality that predictors fail to anticipate (Experiment 4). PMID- 30281403 TI - Cultivation of scenedesmus sp. using optimized minimal nutrients and flocculants a potential platform for mass cultivation. AB - A major constraint in the microalgal technology is the economics involved in cultivation and harvesting. This work is focussed on the optimization of nutrients for cultivation and harvesting using 'Scenedesmus sp'. Response surface methodology (RSM) using 'Face centered central composite design' (FCCD) available in Design expert 10.0.4 was used to develop the regression model for optimization of nutrients and flocculation conditions. The optimum nutrient conditions were 500 ppm of urea, 250 ppm of potassium dihydrogen phosphate and 1000 ppm of potassium hydrogen carbonate under artificial light conditions and 500 ppm of urea and 2000 ppm of potassium hydrogen carbonate under sunlight conditions. The optimum conditions were predicted using the model and compared with experimental data. The model has an R2 value of 0.9769 and 0.9798 for artificial light and sunlight conditions, respectively. In the case of harvesting studies, 98% flocculation efficiency was obtained for a combination of pH 10.4, temperature 45 degrees C, 200 mg/l of leaf powder of Cassia auriculata. The model has an R2 value of 0.9989. The present studies indicated that cultivation of Scenedesmus sp. with the optimized nutrients and harvesting conditions facilitate a platform for energy efficient mass cultivation. PMID- 30281404 TI - Recombinant NS3 Protein Induced Expression of Immune Modulatory Elements in Hepatic Stellate Cells During Its Fibrotic Activity. AB - There is a growing body of studies that show the important role of NS3 protein from hepatitis C virus in fibrosis. However, mechanisms of the effects of this protein on immune modulation of stellate cells remain to be investigated. Herein, the effect of NS3 protein on the expression level of suppressor of cytokine signaling (SOCS)1/3 and interleukin-24 (IL-24)-related genes was investigated in hepatic stellate cell (HSC), LX-2. Recombinant NS3 protein was added to LX-2 HSC culture. Leptin and standard medium treatments were also included in experiments as positive and negative controls, respectively. Total RNA was extracted from each well at 6, 12, and 24 h after NS3 addition. The expression levels of the fibrotic (transforming growth factor beta 1 [TGF-beta], alpha-smooth muscle actin [alpha-SMA], and COL1A1), inflammatory (IL-6 and IL-24), IL-20R, IL-22R, and immunosuppressive genes (SOCS1 and SOCS3) were evaluated by real-time polymerase chain reaction (PCR). Recombinant NS3 protein induced activated phenotypes of LX 2 with a significant increase in the expression level of alpha-SMA COL1A1 (p < 0.0001) and TGF-beta. Moreover, this exposure led to a meaningful elevation in the expression of IL-6. Furthermore, compared with leptin (control), after the stellate cell treatment with NS3, SOCS1 and SOCS3 gene expression induced at a comparable level. Compared with the control sample, the NS3 protein significantly increased the expression level of IL-24 and its related receptors, IL-20R and IL 22R. This study not only confirmed the previously proved inflammatory and fibrotic effect of this protein but also indicated that high expression levels of SOCS1, SOCS3, and IL-24 have a significant effect on HSC activation. Therefore, these two molecules can be used as a potential therapeutic target candidate. PMID- 30281406 TI - Using the categorical data analyses in determination of dust related occupational diseases in mining. AB - Dust related occupational diseases are common in mining sector. It is important to identify employees who have high potential for having these diseases and to investigate the factors affecting disease formation. For this reason, dust and dust related occupational diseases should be carefully investigated in the mining operations. In this study, dust related occupational diseases in an open pit lignite mine were investigated. Firstly, dust measurements were performed and then, health check of all employees was implemented. The obtained data set was categorized by taking into account the occupation, age, experience and level of dust exposure of the employees. While the logistic regression analysis was performed to determine the probability of the diseases, hierarchical loglineer model was established to investigate the factors in the occurrence of the diseases for those employees with the disease. Therefore, the most important factors for the development of the diseases were determined by the hierarchical loglinear model. PMID- 30281405 TI - Chemical use in the semiconductor manufacturing industry. AB - BACKGROUND: The semiconductor industry is known to use a number of chemicals, but little is known about the exact chemicals used due to the ingredients being kept as a trade secret. OBJECTIVES: The objective of this study was to analyze chemical use using a safety data sheet (SDS) and chemical inventory provided by a major semiconductor company, which operated two factories (A and B). METHODS: Descriptive statistics were obtained on the number of chemical products and ingredients, photoresists, and carcinogens, classified by the International Agency for Research on Cancer (IARC), as well as trade secret ingredients. The total chemical use per year was estimated from chemical inventories mass (kg). RESULTS: A total of 428 and 432 chemical products were used in factories A and B, respectively. The number of pure chemical ingredients, after removing both trade secret ingredients and multiple counting, was 189 and 157 in factories A and B, respectively. The number of products containing carcinogens, such as sulfuric acid, catechol, and naphthalene was 47/428 (A) and 28/432 (B). Chemicals used in photolithography were 21% (A) and 26% (B) of all chemical products, and more than 97% among them were chemicals containing trade secret ingredients. CONCLUSIONS: Each year, 4.3 and 8.3 tons of chemicals were used per person in factories A and B, respectively. Because of the high level of commercial secrecy and the use of many unregulated chemicals, more sustainable policies and methods should be implemented to address health and safety issues in the semiconductor industry. PMID- 30281407 TI - Effect of Zingiber officinale Roscoe essential oil in fungus control and deoxynivalenol production of Fusarium graminearum Schwabe in vitro. AB - Members of the Fusarium genus are capable of contaminating agricultural commodities, compromising the quality of maize and other grains, which leads to severe quality and yield losses. Contamination with mycotoxins is also a concern. Essential oils are possible alternatives to the use of synthetic pesticides for control of fungal contamination, as many have antifungal and anti-mycotoxigenic properties and are innocuous to human health. They also do not cause any sort of microbial resistance and do not promote environmental pollution. The aim of this study was to evaluate the antifungal and anti-mycotoxigenic effects of Zingiber officinale Roscoe essential oil (GEO) upon Fusarium graminearum Schwabe in vitro. The essential oil was extracted by hydrodistillation and analysed by GC/MS. Antifungal and anti-mycotoxigenic activities were assessed by HPLC/UV by quantifying ergosterol and deoxynivalenol (DON), respectively. Results indicated that GEO inhibited ergosterol production at a concentration of 1000 ug/mL and DON production at a concentration of 500 ug/mL, evidencing that the anti mycotoxigenic effect is independent of the antifungal effect due to its probable direct action upon toxin biosynthesis. PMID- 30281408 TI - Mir-206 partially rescues myogenesis deficiency by inhibiting CUGBP1 accumulation in the cell models of myotonic dystrophy. AB - OBJECTIVES: In this study, we aim to determine how CUG-expansion and the abundance of Celf1 regulates normal myocyte differentiation and reveal the role ofmiR-206 in myotonic dystrohy and explore a possible gene therapy vector. METHODS: we set up CUG-expansion and Celf1 overexpression C2C12 cell models to imitate the myocyte differentiation defects of DM1, then transfected AdvmiR-206 into cell models, tested the level of myogenic markers MyoD, MyoG, Mef2c, Celf1 by RT-PCRand Western Blotting, detected myotube formation by myosin heavy chain immunostaining. Result: 3'-UTR CUG-expansion leads to myotube defects and impaired myoblasts differentiation. Overexpression of Celf1 inhibits myoblast differentiation and impairs differentiation. Knockdown of Celf1 partially rescues differentiation defects of myoblasts harboring CUG-expansion. miR-206 incompletely reverses myoblast differentiation inhibition induced by CUG expansion and partially recuses myoblast differentiation defects induced by Celf1 overexpression. CONCLUSIONS: Ectopic miR-206 mimicking the endogenous temporal patterns specifically drives a myocyte program that boosts myoblast lineages, likely by promoting the expression of MyoD to rectify the myogenic deficiency by stimulating the accumulation of Celf1. ABBREVIATIONS: DMPK: (dystrophia myotonica protein kinase); 3'-UTR: (3'-untranslated region); MBNL1: (muscleblind-like [Drosophila]); DM1: (myotonic dystrophy type 1); GFP: (green fluorescent protein); RT-PCR: (quantitative reverse transcriptase-polymerase chain reaction); shRNA: (short hairpin RNA). PMID- 30281409 TI - Interview with Shelley E. Taylor. AB - Shelley Taylor's autobiographical interview (conducted by Annual Review of Psychology Editor and long-time collaborator Susan Fiske) touches on some of her favorite ideas. For example, positive illusions: "The traditional textbook definition of mental health included the stipulation that people see the world accurately, and what we were suggesting is that actually, a lot of times, people don't see the world accurately. They see it with a positive spin on it." She also discusses how to found fields (social cognition, health psychology, and social neuroscience) and the challenges of boundary crossing (from social to biological). Her practical comments describe the joy of teaching methods, running a lab, and being a solo female. The interview ends with her advice to follow your instincts about the next big idea: "Trusting your own ideas is a very important way of coming up with a research program that is novel, and exciting, and that ultimately wins people over." Expected final online publication date for the Annual Review of Psychology Volume 70 is January 4, 2019. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates. PMID- 30281410 TI - The changes of systemic immune responses during the neuroprotection induced by remote ischemic postconditioning against focal cerebral ischemia in mice. AB - OBJECTIVE: Remote limb ischemic postconditioning (RIPostC) protects the brain from damage induced by transient focal ischemia/reperfusion. However, the underlying mechanism remains unclear. METHODS: RIPostC induced by 10 min of occlusion and another 10 min releasing of blood flow for three cycles in the hind limbs was performed immediately after the reperfusion in a focal ischemia mice model. Neurological scores, immune cell population in the blood, spleen and lymph node, and inflammatory factors in the blood and brain were analyzed 2 days after the reperfusion. RESULTS: Our results demonstrate that RIPostC reduced cerebral injuries and improved neurological functions 2 days after reperfusion. RIPostC significantly inhibited the reduction in the percentage of CD4 T cells in the spleen and lymph node, CD8 T cells in the blood and lymph node, and natural killer T (NKT) cells in the spleen by flow cytometry analysis. RIPostC attenuated the increase of B cells and NK cells in the spleen and noninflammatory monocytes in the blood. The cytokine assay showed that RIPostC decreased the elevation of IL-10, IL-6, and TNF-alpha in the blood after ischemia. The quantitative real time reverse transcription polymerase chain reaction (qRT-PCR) results indicated that the mRNA level of IL-4 in the brain increased in the middle cerebral artery occlusion mice after RIPostC treatment. CONCLUSIONS: The present study indicates that there were significant changes of inflammatory responses during the neuroprotection induced by RIPostC in stroke mice. PMID- 30281411 TI - Use of traditional and alternative healers by psychiatric patients: A descriptive study in urban South Africa. AB - This study investigates the pattern of use of traditional and alternative healers among psychiatric patients in Nelson Mandela Metropole. An interview schedule was applied to 254 subjects at six sites, enquiring about consultations with traditional and alternative healers in the past year. Multivariate analysis was performed to determine predictors of consultation. Overall, 78 (31%) of respondents had consulted a healer in the past year. The ethnic distribution was: 156 (61%) Black, 53 (21%) Coloured (Mixed Race), 42 (17%) White and three (1%) Indian. The male to female ratio was 119 (46.85%):135 (53.14%). The healers gave no advice about psychiatric medication to 48 (61.5%) of consulters, 23 (29.5%) were told to continue their medication, four (5.1%) told to stop, and one (1.3%) told to stop and restart later. In multivariate models, predictors of consultation were being Black and of lower education. Although 45 (58%) of the consulters indicated that medical treatment was more helpful than the healer's, 45 (58%) intended to consult again. Overall, 22% of consulters reported abuse by the healer. PMID- 30281412 TI - Stroke hospital admission rates in Brisbane and Queensland in 2015: Data from 11,072 cases. AB - Background and aims Little data exist on the incidence of stroke in Australia. Our aim was to report age and sex disparities in hospital admission for stroke in Queensland, Australia's most populous northern state. Methods We identified all patients admitted to hospital in Queensland with a diagnosis of stroke from January to December 2015. Results Among 25,776 admissions with a diagnosis of stroke or TIA and related sequelae, stroke was the principal diagnosis in 11,072 cases of whom 5270 (47.60%) were first-ever stroke. Based on incidents per 100,000 population per year, the crude annual admission rate for first-ever strokes was 110 (95% CI, 107 to 113), 120 (95% CI, 115 to 124) for men and 101 (95% CI, 97 to 105) for women. The corresponding rates adjusted to the world population were 69 (95% CI, 52 to 85), and 88 (95% CI, 70 to 107) adjusted to the European population. Gender and age-adjusted incidence was greater for men than women in all age-groups, except those aged 30-34 years, where occurrence was 10 for men and 16 for women. Conclusions Based on the outcomes, hospital admission for stroke occurs less frequently in Queensland than in other regions of Australia. Men generally show a higher rate of hospitalization than women, with the notable exception of women aged 30-34, for whom the trend reverses. PMID- 30281414 TI - Factors associated with 1-year mortality after discharge for acute stroke: what matters? AB - OBJECTIVE: To evaluate factors associated with 1-year mortality after discharge for acute stroke. METHODS: In this retrospective cohort study, we studied 305 patients with ischemic stroke or intracerebral hemorrhage discharged in 2010/2011. We linked Get With The Guidelines(r)-Stroke clinical data with New York State administrative data and used multivariate regression models to examine variables related to 1-year all-cause mortality poststroke. RESULTS: The mean age was 68.6 +/- 14.8 years and 51.1% were women. A total of 146 (47.9%) were discharged directly home, 96 (31.5%) to inpatient rehabilitation facilities (IRFs), and 63 (20.7%) to skilled nursing facilities (SNFs). Overall, 24 (7.9%) patients died within 1-year post-discharge. Older age (adjusted odds ratio [OR] 1.05, 95% confidence interval [CI] 1.00-1.10), higher National Institutes of Health Stroke Scale (NIHSS) on admission (OR 1.10, 95% CI 1.03-1.17), and discharge destination (IRF vs. home, OR 0.10, 95% CI 0.01-0.94; and SNF vs. home, OR 2.22, 95% CI 0.71-6.95) were factors associated with 1-year all-cause mortality. When ambulation status at discharge was added to the model, ambulation with assistance and non-ambulation were significantly associated with mortality (ambulatory with assistance vs. ambulatory, OR 9.42, 95% CI 1.87-47.61; nonambulatory vs. ambulatory, OR 12.65, 95% CI 1.89-84.89). CONCLUSIONS: While age and NIHSS on admission are important predictors of long-term outcomes, factors at discharge - ambulation status at discharge and discharge destination - are associated with 1-year mortality post-discharge for acute stroke and therefore could represent therapeutic targets to improve long-term survival in future studies. PMID- 30281415 TI - Rasch analysis of the upper-limb subscale of the stroke rehabilitation assessment of movement (STREAM) tool in an acute stroke cohort Rasch analysis of the upper limb subscale of the STREAM tool in an acute stroke population. AB - BACKGROUND: Stroke is a leading cause of disability worldwide. The most common impairment resulting from stroke is upper-limb weakness. OBJECTIVES: To determine the usefulness and psychometric validity of the upper-limb subscale of the STREAM in an acute stroke population. METHODS: Rasch Analysis, including unidimensionality assumption testing, determining model fit, and analysis of: reliability, residual correlations, and differential item functioning. RESULTS: 125 individuals were assessed using the upper-limb subscale of the Stroke Rehabilitation Assessment of Movement (STREAM) tool. Rasch analysis suggests the STREAM is a unidimensional measure. However, when scored using the originally proposed method (0-2), or using the response pattern (0-5) neither variant fit the Rasch model (p < 0.05). Although, the reliability was good (Person-Separation Index - 0.847 and 0.903, respectively). Correcting for the disordered thresholds, and thereby producing the new scoring pattern, led to substantial improvement in the overall fit (chi-square probability of fit - 22%), however, the reliability was slightly reduced (PSI - 0.806). CONCLUSIONS: The study proposes a new scoring method for the upper-limb subscale of the STREAM outcome measure in the acute stroke population. PMID- 30281413 TI - Occupational health and safety in cannabis production: an Australian perspective. AB - The legal Australian cannabis industry has been rapidly expanding due to increased awareness of the plant's therapeutic potential, as well its diverse range of applications including biofuel, textiles, building materials, food, nutritional supplement, and animal feed. The objective of this paper is to describe the current landscape of the commercial Australian cannabis industry, summarise occupational health and safety (OHS) hazards in cannabis-related working environments, and provide suggestions for safeguarding worker health and well-being in this emerging industry. A comprehensive search of peer-reviewed and grey literature published between 1900 and 2017 was undertaken to identify case studies and original epidemiological research on OHS hazards associated with the cannabis cultivation and the manufacture of cannabis-based products. The review found that the majority of OHS studies were undertaken in the hemp textile industry during the late twentieth century, with a small number of articles published from a variety of occupational environments including forensic laboratories and recreational marijuana farms. Cannabis harvesting and initial processing is labour intensive, and presents a physical hazard Depending on the operation, workers may also be exposed to a variety of biological, chemical, and physical hazards including: organic dusts, bioaerosols, pollen/allergens, volatile organic compounds, psychoactive substances (tetrahydrocannabinol [THC])), noise, and ultraviolet radiation. Little research has been undertaken on the exposure to inhalable organic dust and other bioaerosols during the commercial cultivation and manufacture of cannabis-based products. Furthermore, there is an absence of Australian-based research and OHS guidance materials to help professionals develop risk management strategies in this evolving industry. It is recommended that: Investigation into the toxicological properties of cannabis dusts, specifically in relation to potential occupational exposures during cultivation and manufacture, should be a priority. The interim adoption of the respirable cotton dust exposure standard of 0.2 mg/m3 for workplace exposure in hemp facilities until a cannabis workplace exposure standard is developed, and that exposure to medicinal cannabis containing THC are kept as low as reasonably practicable. An industry partnership be established for the development of an Australian health and safety guideline for the production of medicinal cannabis and hemp. A classification to meet the requirements of the Global Harmonization Scheme should be undertaken to ensure consistency in the use of safety and risk phrases in cannabis-related industries. PMID- 30281416 TI - Poor Splice-Site Recognition in a Humanized Zebrafish Knockin Model for the Recurrent Deep-Intronic c.7595-2144A>G Mutation in USH2A. AB - The frequent deep-intronic c.7595-2144A>G mutation in intron 40 of USH2A generates a high-quality splice donor site, resulting in the incorporation of a pseudoexon (PE40) into the mature transcript that is predicted to prematurely terminate usherin translation. Aberrant USH2A pre-mRNA splicing could be corrected in patient-derived fibroblasts using antisense oligonucleotides. With the aim to study the effect of the c.7595-2144A>G mutation and USH2A splice redirection on retinal function, a humanized zebrafish knockin model was generated, in which 670 basepairs of ush2a intron 40 were exchanged for 557 basepairs of the corresponding human sequence using an optimized CRISPR/Cas9 based protocol. However, in the retina of adult homozygous humanized zebrafish, only 7.4% +/- 3.9% of ush2a transcripts contained the human PE40 sequence and immunohistochemical analyses revealed no differences in the usherin expression and localization between the retina of humanized and wild-type zebrafish larvae. Nevertheless, we were able to partially correct aberrant ush2a splicing using a PE40-targeting antisense morpholino. Our results indicate a clear difference in splice-site recognition by the human and zebrafish splicing machinery. Therefore, we propose a protocol in which the effect of human splice-modulating mutations is studied in a zebrafish-specific cell-based splice assay before the generation of a humanized zebrafish knockin model. PMID- 30281417 TI - Trunk alignment in different standing positions in healthy subjects and stroke patients -a comparative study with a simple method for the everyday practice.: Trunk alignment in healthy and stroke subjects. AB - OBJECTIVES: Weight-bearing (WB) on the lower extremities is an important outcome parameter in the rehabilitation of poststroke hemiparesis. However, the patients often regain this ability by compensatory movement patterns. METHODS: Our goal was to characterize with a simple method the trunk alignment of healthy subjects and stroke patients (n = 17 for both groups) during standing and following lateral weight shift (WS). To describe trunk alignment, five markers were placed on the subjects' back, and the angles of the trunk at both sides were defined by the lines drawn from the posterior angle of the acromion and the iliac crest on the same body side to the seventh thoracic spinal process. Weight distributions on the lower extremities during standing and lateral WS were determined with a force platform. RESULTS: The patients had significantly limited WB capacity on their paretic limb, which was accompanied with significant asymmetry in the trunk alignment during standing and following WS to the paretic side. DISCUSSION: Our results show that this patient population tends to use abnormal compensatory movement patterns to optimize weight shifting, and changes of trunk alignment play a key role in this. This should be taken into consideration during rehabilitation. PMID- 30281418 TI - Hybrid Soft-Rigid Actuators for Minimally Invasive Surgery. AB - Fluidic mechanisms have stimulated research and development in minimally invasive surgery instrumentations, because of their good performance in limited size and their force/torque generation with respect to other types of actuation systems. Fluidic solutions can be divided in two major classes: (i) elastic fluidic actuators and (ii) piston-cylinder actuators. Elastic fluidic actuators generate lower forces with smaller displacements; nevertheless, piston-cylinder solutions require seals, which can generate friction and require maintenance costs for a good reliability. The proposed solution is based on a hybrid soft-rigid actuation, which aims to overcome the limitations of both previous solutions while preserving the main advantages of the overall fluidic approach. This approach results in very compact, powerful, and low-cost actuators, which are highly customizable and adaptable to specific constraints, in medical applications but even beyond. This article proposes a novel design of hybrid soft rigid actuators to be used as basic mechanical joints for enabling pitch and roll degrees of freedom for a miniature robotic arm. Forces up to 1.4 N and up to 2.77 N have been obtained for the above joints, respectively, and even better performance can be reached (up to 3 N) with further improvements, as demonstrated in this article. PMID- 30281419 TI - Verticillium Wilt on Fiber Flax: Symptoms and Pathogen Development In Planta. AB - Fiber flax (Linum usitatissimum L.), an important crop in Normandy (France), is increasingly affected by Verticillium wilt caused by the soilborne fungus Verticillium dahliae. This disease leads to nonnegligible yield losses and depreciated fibers that are consequently difficult to upgrade. Verticillium wilt is a major threat to a broad range of agriculture. In this study, susceptible fiber flax cultivar Adelie was infected by VdLu01 (isolated from fiber flax, this study) or green fluorescent protein-tagged VdLs17 (transformed and provided by the department of Plant Pathology, University of California, Davis). Between 3 and 4 weeks postinoculation, wilting symptoms on leaves were first observed, with acropetal growth during the following weeks. Pathogen development was tracked by confocal laser-scanning microscopy during the asymptomatic and symptomatic stages. First, conidia germination led to the development of hyphae on root epidermis; more particularly, on the zone of cell differentiation and around emerging lateral roots, while the zone of cell division and the root tip were free of the pathogen. At 3 days postinoculation, the zone of cell differentiation and lateral roots were embedded into a fungal mass. Swelling structures such as appressoria were observed at 1 week postinoculation. At 2 weeks postinoculation and onward, the pathogen had colonized xylem vessels in roots, followed by the stem and, finally, leaves during the symptomatic stage. Additionally, observations of infected plants after retting in the field revealed microsclerotia embedded inside the bast fiber bundle, thus potentially contributing to weakening of fiber. All of these results provide a global account of V. dahliae development when infecting fiber flax. PMID- 30281420 TI - Epidemics and Yield Losses due to Corynespora cassiicola on Cotton. AB - Target spot, caused by Corynespora cassiicola, has recently emerged as a problematic foliar disease of cotton. This pathogen causes premature defoliation during boll set and maturation that can subsequently impact yield, and on certain cotton cultivars loss can be substantial. This study sought to better understand target spot epidemics and disease-incited yield losses on cotton. In order to establish a range of disease, varying numbers of fungicide applications were made to each of two cotton cultivars in each of four site-years. Target spot intensity was rated over several dates beginning in late July or early August and continuing into September. Yield of seed plus lint (seed cotton) was recorded at harvest. When analyzed across cultivars, a second or third fungicide application increased yield compared with no treatment. Lack of significant yield response with a single fungicide application may have been due to timing of that application which preceded disease onset. The cultivar PhytoGen 499 WRF had consistently greater defoliation than any of the three Deltapine cultivars grown in each site-year. However, yields of both cultivars responded similarly to the fungicide regimes. Yield loss models based on late August defoliation were only predictive at site-years where conditions favored target spot development, i.e., abundant rain and moderate temperatures. Epidemic development fit the Gompertz growth model better than it did a logistic model. Knowledge of the underlying mathematical character of the epidemiology of target spot will prove useful for development of a predictive model for the disease. PMID- 30281421 TI - Influence of Cotton Root System Size on Tolerance to Rotylenchulus reniformis. AB - The factors that influence the ability of cotton to minimize yield loss despite parasitism by Rotylenchulus reniformis (i.e., tolerance) were evaluated for 12 cotton genotypes. Reproduction of R. reniformis and total length of the root system were measured under greenhouse conditions, and the relationship of those variables to yield loss caused by R. reniformis in infested fields was evaluated. Values for nematodes per gram of root and root length were standardized by setting the genotype with greatest value as 100% and then calculating a percentage for each genotype. There was significant variability among genotypes in yield loss, resistance, and root length. Average yield loss for the genotypes ranged from 10.4% for IAC 26RMD to 43.2% for IMACD 5675B2RF. The least nematode reproduction was on IAC 26RMD, which had 49.6% of the reproduction on the susceptible check, Deltapine 16. The genotype with the shortest total root length was 34% less than the genotype with the greatest length. There was a significant linear relationship between percentage yield loss caused by R. reniformis and root length and nematodes per gram of root, both expressed as a percentage of the maximum, represented by the following equation: Yield loss (%) = 16.1258 - 0.1918*(% maximum root length) + 0.3728*(% maximum eggs + vermiform/g of roots). We conclude that tolerance to R. reniformis in cotton is influenced by the size of the root system and the parasitic load on the plant (nematodes per gram of root). Management approaches that increase root growth may lower the parasitic load, thereby reducing losses in cotton to R. reniformis. PMID- 30281422 TI - Unsupervised Semantic-Based Aggregation of Deep Convolutional Features. AB - In this paper, we propose a simple but effective semantic-based aggregation (SBA) method. The proposed SBA utilizes the discriminative filters of deep convolutional layers as semantic detectors. Moreover, we propose the effective unsupervised strategy to select some semantic detectors to generate the "soft region proposals," which highlight certain discriminative pattern of objects and suppress the noise of background. The final global SBA representation could then be acquired by aggregating the regional representations weighted by the selected "soft region proposals" corresponding to various semantic content. Our unsupervised SBA is easy to generalize and achieves excellent performance on various tasks. We conduct comprehensive experiments and show that our unsupervised SBA outperforms the state-of-the-art unsupervised and supervised aggregation methods on image retrieval, place recognition, and cloud classification. PMID- 30281423 TI - Wrist and Finger Gesture Recognition with Single-element A-mode Ultrasound signal: A Comparison with Single-channel Surface Electromyogram. AB - With the ability to detect volumetric changes of contracting muscles, ultrasound (US) was a potential technique in the field of human-machine interface (HMI). Compared to the US imaging (B-mode US), the signal from a static single-element US transducer, A-mode US, was a more cost-effective and convenient way towards the real-world application, particularly the wearables. This study compared the performance of the single-channel A-mode US with single-channel surface electromyogram (sEMG) signals, one of the most popular signal modalities for wrist and finger gesture recognition. We demonstrated that A-mode US outperformed sEMG in six out of nine gestures recognition, while sEMG was superior to A-mode US on the detection of the Rest state. We also demonstrated that, through feature space analysis, the advantage of A-mode US over sEMG for gesture recognition was due to its superior ability in detecting information from deep musculature. This study presented the clear complementary advantages between A-mode US and sEMG, indicating the possibility of fusing two signal modalities for the gesture recognition applications. PMID- 30281424 TI - Deep Learning Models Unveiled Functional Difference between Cortical Gyri and Sulci. AB - It is largely unknown whether there is functional role difference between cortical gyral and sulcal regions. Recent advancements in neuroimaging studies demonstrate clear difference of structural connection profiles in gyral and sulcal areas, suggesting possible functional role difference in these convex and concave cortical regions. To explore and confirm such possible functional difference, we design and apply a powerful deep learning model of convolutional neural networks (CNN) that has been proven to be superior in learning discriminative and meaningful patterns on fMRI. By using the CNN model, gyral and sulcal fMRI signals are learned and predicted, and the prediction performance is adopted to demonstrate the functional difference between gyri and sulci. By using the Human Connectome Project (HCP) fMRI data and macaque brain fMRI data, an average of 83% and 90% classification accuracy has been achieved to separate gyral/sulcal HCP task fMRI signals at the population and individual subject level respectively; 81% and 86% classification accuracy for resting state fMRI signals at the group and individual subject level respectively. In addition, 78% classification accuracy has been achieved to separate gyral/sulcal resting state fMRI signals in macaque brains. Importantly, further analysis reveals that the discriminative features that are learned by CNNs to differentiate gyral/sulcal fMRI signals can be meaningfully interpreted, thus unveiling the fundamental functional difference between cortical gyri and sulci. That is, gyri are more global functional integration centers with simpler lower frequency signal components, while sulci are more local processing units with more complex higher frequency signal components. PMID- 30281425 TI - Sensitivity of shoulder musculoskeletal model predictions to muscle-tendon properties. AB - OBJECTIVE: While the sensitivity of estimated muscle forces to muscle-tendon properties is well documented for the lower limbs, little is known about the shoulder and upper limbs. The purpose of this study was to assess the sensitivity of estimated shoulder muscle forces and scapulohumeral joint force to muscle tendon properties. METHODS: One healthy male participant performed arm flexions and simulated throwing maneuvers. Kinematics were recorded using intra-cortical pins. Muscle forces were estimated using static optimization with the generic Delft Shoulder and Elbow in OpenSim, and scapulohumeral joint forces were calculated from the estimated forces. Then, variations from - 25% to +25% of the nominal values of the tendon slack length, the optimal fiber length, the maximal isometric force and the pennation angle were applied to the musculoskeletal model to compute affected muscle forces and scapulohumeral joint force. RESULTS: The variations in muscle-tendon properties led to changes up to 9.6 N or 174% in the muscle nominal forces. The more sensitive muscles were those that produced the greatest force: the rotator cuff muscles and the prime movers specific to the task. Among the four muscle-tendon properties, the maximal isometric force and the optimal fiber length had the greatest influence on the muscle force variability. Glenohumeral force was slightly influenced by muscle-tendon properties (). CONCLUSION: Generic models (i.e., those without personalization of muscle-tendon properties) can lead to misinterpretations of muscle force. Efforts should focus on the maximal isometric force and the optimal fiber length of the rotator cuff muscles and prime movers.

This integration may ultimately enable improved classification and treatment of asthma. Severe asthma (15% of asthmatics) is particularly challenging to treat, as these patients do not respond well to inhaled therapeutics. METHODS: This study combines medical image data with patient-specific computational models to predict gas distributions and airway mechanics in healthy and asthmatic subjects. We achieve this by integrating segmental volume defect percent (SVDP), measured from hyperpolarized 3He MRI and CT images, to create models of patient-specific gas flow within the conducting airways. Predicted and measured SVDP distributions are achieved when the prescribed resistances are increased systematically. RESULTS: Because of differences in airway morphology and regional function, airway resistances and flow structures varied between the asthmatic subjects. Specifically, while mean SVDP was similar between the severe asthmatics (4.30+/ 5.22 versus 3.54+/-5.98%), one subject exhibited abnormal flow structures, high near wall flow gradients, and enhanced conducting airway resistances (17.3E 3versus 1.1E-3 cmH2O-s/mL) in comparison to the other severe asthmatic subject. CONCLUSION: By coupling medical imaging data with computer simulations, we provide detailed insight into pathological flow characteristics and airway mechanics in asthmatics, beyond what could be inferred independently.

AB - OBJECTIVE: This numerical study was designed to evaluate the feasibility of using an inductive coil for monitoring the changes in the volume of a hematoma in the head in situ and to compare the inductive coil performance to that of a spiral antenna based on the radar principle. METHODS: Numerical analysis was used to solve the complete set of Maxwell's equations in full 3D anatomical model of a head and brain with data on clinical occurrence of hematomas from the clinical literature, for frequencies of 100 MHz, 500 MHz and 1 GHz. RESULTS: (1) The analysis shows that the spiral radar antenna provides a better resolution when the antenna can be placed exactly facing the center of the volume of blood. Under any other circumstance, the inductive coil has a better resolution at both 500 MHz and 1 GHz. (2) The induction coil is more sensitive to rotation artifacts than the spiral antenna. (3) Single frequency measurements do not provide conclusive results. CONCLUSION: The inductive coil has the ability to monitor small changes in the volume of a hematoma in the head. However, multifrequency measurements are required for correct diagnostic. SIGNIFICANCE: This study provides a new, low cost alternative to conventional medical imaging for monitoring hematoma increase. PMID- 30281429 TI - Flexible Platform for In Situ Impedimetric Detection and Bioelectric Effect Treatment of Escherichia coli Biofilms. AB - GOAL: This paper reports a platform for real-time monitoring and treatment of biofilm formation on 3D biomedical device surfaces. METHODS: We utilize a flexible platform consisting of gold interdigitated electrodes patterned on a polyimide substrate. The device was integrated onto the interior of a urinary catheter and characterization was performed in a custom-developed flow system. Biofilm growth was monitored via impedance change at 100 Hz AC with a 50 mV signal amplitude. RESULTS: A 30% impedance decrease over 24 hours corresponded to Escherichia coli biofilm formation. The platform also enabled removal of the biofilm through the bioelectric effect; a low concentration of antibiotic combined with the applied AC voltage signal led to a synergistic reduction in biofilm resulting in a 12% increase in impedance. Biomass characterization via crystal violet staining confirmed that the impedance detection results correlate with changes in the amount of biofilm biomass on the sensor. We also demonstrated integration with a chip-based impedance converter to enable miniaturization and allow in situ wireless implementation. A 5% impedance decrease measured with the impedance converter corresponded to biofilm growth, replicating the trend measured with the potentiostat. CONCLUSION: This platform represents a promising solution for biofilm infection management in diverse vulnerable environments. SIGNIFICANCE: Biofilms are the dominant mode of growth for microorganisms, where bacterial cells colonize hydrated surfaces and lead to recurring infections. Due to the inaccessible nature of the environments where biofilms grow and their increased tolerance of antimicrobials, identification and removal on medical devices poses a challenge. PMID- 30281430 TI - Lung ultrasound surface wave elastography for assessing interstitial lung disease. AB - OBJECTIVE: Our goal is to translate lung ultrasound surface wave elastography (LUSWE) for assessing patients with interstitial lung disease (ILD) and various connective tissue diseases including systemic sclerosis (SSc). METHODS: LUSWE was used to measure the surface wave speed of lung at 100 Hz, 150 Hz and 200 Hz through six intercostal lung spaces for 91 patients with ILD and 30 healthy control subjects. In addition, skin viscoelasticity was measured on both forearms and upper arms for patients and controls. RESULTS: The surface wave speeds of patients' lungs were significantly higher than those of control subjects. Patient skin elasticity and viscosity were significantly higher than those of control subjects. In dividing ILD patients into two groups, ILD with SSc patients and ILD without SSc patients, significant differences between each patient group with the control group were found for both the lung and skin. No significant differences were found between the two patient groups, although there were some differences at a few locations and at 100 Hz. for skin viscoelasticity. CONCLUSION: Significant differences of surface wave speed were found between ILD patients and healthy control subjects for both the lung and skin. SIGNIFICANCE: LUSWE may be useful for assessing ILD and SSc and screening early stage patients. PMID- 30281428 TI - Three-Dimensional Brain-Computer Interface Control Through Simultaneous Overt Spatial Attentional and Motor Imagery Tasks. AB - OBJECTIVE: While noninvasive electroenceph-alography (EEG) based brain-computer interfacing (BCI) has been successfully demonstrated in two-dimensional (2-D) control tasks, little work has been published regarding its extension to practical three-dimensional (3-D) control. METHODS: In this study, we developed a new BCI approach for 3-D control by combining a novel form of endogenous visuospatial attentional modulation, defined as overt spatial attention (OSA), and motor imagery (MI). RESULTS: OSA modulation was shown to provide comparable control to conventional MI modulation in both 1-D and 2-D tasks. Furthermore, this paper provides evidence for the functional independence of traditional MI and OSA, as well as an investigation into the simultaneous use of both. Using this newly proposed BCI paradigm, 16 participants successfully completed a 3-D eight-target control task. Nine of these subjects further demonstrated robust 3-D control in a 12-target task, significantly outperforming the information transfer rate achieved in the 1-D and 2-D control tasks (29.7 +/- 1.6 b/min). CONCLUSION: These results strongly support the hypothesis that noninvasive EEG-based BCI can provide robust 3-D control through endogenous neural modulation in broader populations with limited training. SIGNIFICANCE: Through the combination of the two strategies (MI and OSA), a substantial portion of the recruited subjects were capable of robustly controlling a virtual cursor in 3-D space. The proposed novel approach could broaden the dimensionality of BCI control and shorten the training time. PMID- 30281431 TI - Comparison of Bipolar and Unipolar Pulses in Cell Electrofusion: Simulation and Experimental Research. AB - OBJECTIVE: Unipolar pulses have been used in cell electrofusion over the last decades. However, the problem of high mortality with unipolar pulses has not been solved effectively. The cell fusion rate is restrict by cell mortality. By using the advantages of bipolar pulses which cause less cell damage, this paper attempts to use bipolar pulses to increase the cell fusion rate. METHODS: The transmembrane voltage and pore density of cells subjected to unipolar/bipolar pulses were simulated in COMSOL software. In an experiment, two 40 MUs unipolar and two 20 MUs-20 MUs bipolar pulses with electric fields of 2 kV/cm, 2.5 kV/cm, and 3 kV/cm were applied to SP2/0 murine myeloma cells. To determine the cell fusion rate and cell mortality, cells were stained with Hoechst 33342 and propidium iodide. RESULTS: The simulation in this paper showed that a high transmembrane voltage and a high pores density were concentrated only at the contact area of cells when bipolar pulses were used. The results of the cell staining experiment verified the simulation analysis. When bipolar pulses were applied, the cell mortality was significantly reduced. In addition, the cell fusion rate with bipolar pulses was almost two times higher than that with unipolar pulses. CONCLUSION: For cell electrofusion, compared with unipolar pulses, bipolar pulses can not only reduce the cell mortality remarkably but also improve the cell fusion rate obviously. SIGNIFICANCE: This article introduces a novel way to increase the fusion rate of cells. PMID- 30281432 TI - Reconstruction of Fluorescence Molecular Tomography via a Fused LASSO Method Based on Group Sparsity Prior. AB - OBJECTIVE: The aim of this study is to improve the reconstruction accuracy in both position and source region of fluorescence molecular tomography (FMT). METHODS: The reconstruction of FMT is challenging due to its serious ill posedness and ill-condition. Currently, to obtain the fluorescent sources accurately, more a priori information of the fluorescent sources is utilized and more efficient and practical methods are proposed. In this paper, we took the group sparsity of the fluorescent sources as a new type of priori information in FMT, and proposed the fused LASSO method (FLM) for FMT. The FLM based on group sparsity prior not only takes advantage of the sparsity of the fluorescent sources, but also utilizes the structure of the sources, thus making the reconstruction results more accuracy and morphologically similar to the sources. To further improve the reconstruction efficiency, we adopt Nesterov's method to solve the FLM. RESULTS: Both heterogeneous numerical simulation experiments and in vivo mouse experiments were carried out to verify the property of FLM. The results have verified the superiority of FLM over conventional methods in tumor detection and tumor morphological reconstruction. Furthermore, the in vivo experiments had demonstrated that the FLM has great potential in preclinical application of FMT. SIGNIFICANCE: The reconstruction method based on group sparsity prior has a great potential in FMT study, it can further improve the reconstruction quality, which has practical significance in preclinical research. PMID- 30281433 TI - Optogenetic excitation of ipsilesional sensorimotor neurons is protective in acute ischemic stroke: a laser speckle imaging study. AB - OBJECTIVE: Directly modulating targeted cortical function, brain stimulation provides promising techniques for stroke intervention. However, the cellular level mechanisms underlying preserved neurovascular function remains unclear. Optogenetics provides cell-specific approach to modulate neuronal activity. This study aims to investigate whether the exclusive excitation of sensorimotor neurons using optogenetics in acute stroke can protect neurovascular function and reduce infarct size. METHODS: Sensorimotor neurons were transfected with channelrhodopsin-2 and excited by 473 nm laser. Photothrombotic stroke was induced in the ipsilateral parietal cortex and the targeted area for modulation remained intact. Optogenetic stimulation was carried out within 2 hrs after stroke in the modulation group. Using laser speckle contrast imaging technique, we measured the cerebral blood flow at baseline, 0 hr, 2hrs and 24 hrs after stroke, and analyzed the hemodynamic changes in both modulation (n=12) and control (n=9) groups. Also, neurovascular response was measured 24 hrs after stroke. RESULTS: We found that neuronal-specific excitation of ipsilesional sensorimotor cortex at acute stage could reduce the expansion of ischemic area and promote the neurovascular response at 24 hrs after stroke. The histological and behavioral results consolidate the protective effects of optogenetic-guided neuronal modulation in acute stroke. CONCLUSION: Excitatory stimulation of ipsilesional sensorimotor neurons in acute stroke could protect neurovascular function and reduces expansion of ischemic area. SIGNIFICANCE: For the first time, this work demonstrates that specific neuronal modulation in acute stroke is neuroprotective and reduces infarct size. PMID- 30281434 TI - Localization of Activation Origin on Patient-Specific Epicardial Surface by Empirical Bayesian Method. AB - OBJECTIVE: Ablation treatment of ventricular arrhythmias can be facilitated by pre-procedure planning aided by electrocardiographic inverse solution, which can help to localize the origin of arrhythmia. Our aim was to improve localization accuracy of the inverse solution by using a novel Bayesian approach. METHODS: The inverse problem of electrocardiography was solved by reconstructing epicardial potentials from 120 body-surface electrocardiograms and from patient-specific geometry of the heart and torso for 4 patients suffering from scar-related ventricular tachycardia who underwent epicardial catheter mapping which included pace-mapping. Simulations using dipole sources in patient-specific geometry were also performed. The proposed method, using dynamic spatio-temporal a priori constraints of the solution, was compared with classical Tikhonov methods based on fixed constraints. RESULTS: The mean localization error of the proposed method for all available pacing sites (n = 78) was significantly smaller than that achieved by Tikhonov methods; specifically, the localization accuracy for pacing in the normal tissue (n = 17) was 8+/-6 mm (mean+/-SD) versus 13+/-9 mm (P < 0.00001) reported in the previous study using the same clinical data and Tikhonov regularization. Simulation experiments further supported these clinical findings. CONCLUSION: The promising results of in vivo and in silico experiments presented in this study provide a strong incentive to pursuing further investigation of data-driven Bayesian methods in solving the electrocardiographic inverse problem. SIGNIFICANCE: The proposed approach to localizing origin of ventricular activation sequence may have important applications in pre-procedure assessment of arrhythmias and in guiding their ablation treatment. PMID- 30281435 TI - Roll off displacement in ex vivo experiments of RF ablation with refrigerated saline solution and refrigerated deionized water. AB - OBJECTIVE: The recurrence rate in the treatment of liver tumors using radiofrequency ablation (RFA) is often related to incomplete tissue necrosis and consequently the limitation in the ablation volume. This paper proposes an ablation protocol combined with the infusion of saline solution and deionized water aiming at achieving a time displacement in the roll-off occurrence and consequently increasing the volume of ablation. METHODS: An infusion of saline solution and deionized water at 5 degrees C and 23 degrees C was performed to evaluate the influence of these liquids on the RFA procedure in ex vivo bovine liver pieces. The results obtained were used to propose a mathematical model of the roll-off phenomenon by means of systems identification techniques. RESULTS: The RFA combined with the infusion of saline solution 0.9% at 5 degrees C presented optimal results, with a time delay of the roll-off occurrence in 27.8% compared to pure RFA (p = 0.002) and an increase in the necrotic volume of 51.2% (p = 0.0002). Two Box-Jenkins models were obtained to describe the roll-off phenomenon: (i) pure RFA and (ii) RFA combined with the saline solution 0.9% at 5 degrees C. CONCLUSION: The RFA therapy combined with the saline solution 0.9% at 5 degrees C increases the time range to the roll-off occurrence, leading to higher necrosis volumes in ex vivo bovine liver samples. The development of a mathematical model to describe the roll-off behavior demonstrated that the transient response is improved by the infusion of the saline solution 0.9% at 5 degrees C. PMID- 30281436 TI - Real-Time Blood Pressure Estimation From Force-Measured Ultrasound. AB - OBJECTIVE: Our objective is to create a blood pressure measurement device, which may provide a way to easily acquire frequent measurements. Common techniques to measure blood pressure include an arterial catheter, an oscillometric pressure cuff, or an auscultatory pressure cuff. METHODS: The approach takes as input ultrasound images of an artery and contact force between the ultrasound array and subject. A subject may perform the self-measurements. Image and force data is analyzed for its quality and used to provide guidance or reject poor measurements. Tissue motions, due to probe contact forces and pulsing blood pressure, are estimated from the ultrasound image. Tissues elasticities and blood pressure are found by optimally fitting the observed tissue motion versus applied forces to a table of predicted motion-pre-generated with a finite element tissue deformation model. The output of the optimization is an estimate of systolic and diastolic blood pressure, arterial stiffness, and surrounding tissue stiffness. RESULTS: The real-time implementation of the algorithm was validated on a cohort of 21 single-visit volunteers and on four volunteers self-monitored longitudinally. The systolic and diastolic pressures were compared to oscillometric cuff readings. Regression and Bland-Altman analyses were performed. CONCLUSION: Systolic pressure and diastolic pressure can be estimated in real time and by the subject using this novel non-invasive ultrasound-based method (systolic accuracy/precision: -5.2 mmHg/10.7 mmHg; diastolic accuracy/precision: 3.9/8.0 mmHg). SIGNIFICANCE: The method occupies a middle ground between the arterial catheter and cuff-based techniques. It has the potential to give calibration-free results. PMID- 30281437 TI - A Novel Geometric Framework on Gram Matrix Trajectories for Human Behavior Understanding. AB - In this paper, we propose a novel space-time geometric representation of human landmark configurations and derive tools for comparison and classification. We model the temporal evolution of landmarks as parametrized trajectories on the Riemannian manifold of positive semidefinite matrices of fixed-rank. Our representation has the benefit to bring naturally a second desirable quantity when comparing shapes - the spatial covariance - in addition to the conventional affine-shape representation. We derived then geometric and computational tools for rate-invariant analysis and adaptive re-sampling of trajectories, grounding on the Riemannian geometry of the underlying manifold. Specifically, our approach involves three steps: (1) landmarks are first mapped into the Riemannian manifold of positive semidefinite matrices of fixed-rank to build time-parameterized trajectories; (2) a temporal warping is performed on the trajectories, providing a geometry-aware (dis-)similarity measure between them; (3) finally, a pairwise proximity function SVM is used to classify them, incorporating the (dis )similarity measure into the kernel function. We show that such representation and metric achieve competitive results in applications as action recognition and emotion recognition from 3D skeletal data, and facial expression recognition from videos. Experiments have been conducted on several publicly available up-to-date benchmarks. PMID- 30281438 TI - Semi-Calibrated Photometric Stereo. AB - While conventional calibrated photometric stereo methods assume that light intensities and sensor exposures are known or unknown but identical across observed images, this assumption easily breaks down in practical settings due to individual light bulb's characteristics and limited control over sensors. This paper studies the effect of unknown and possibly non-uniform light intensities and sensor exposures among observed images on the shape recovery based on photometric stereo. This leads to a development of a "semi-calibrated" photometric stereo method, where the light directions are known but light intensities (and sensor exposures) are unknown. We show that the semi-calibrated photometric stereo becomes a bilinear problem, whose general form is difficult to solve, but in the photometric stereo context, there exists a unique solution for the surface normal and light intensities (or sensor exposures). We further show that there exists a linear solution method for the problem, and develop efficient and stable solution methods. The semicalibrated photometric stereo is advantageous over a conventional calibrated photometric stereo in accurate determination of surface normal because it relaxes the assumption of known light intensity ratios/sensor exposures. The experimental results show superior accuracy of the semi-calibrated photometric stereo in comparison to conventional methods in practical settings. PMID- 30281439 TI - Holistic CNN Compression via Low-rank Decomposition with Knowledge Transfer. AB - Convolutional neural networks (CNNs) have achieved remarkable success in various computer vision tasks, which are extremely powerful to deal with massive training data by using tens of millions of parameters. However, CNNs often cost significant memory and computation consumption, which prohibits their usage in resource-limited environments such as mobile or embedded devices. To address the above issues, the existing approaches typically focus on either accelerating the convolutional layers or compressing the fully-connected layers separatedly, without pursuing a joint optimum. In this paper, we overcome such a limitation by introducing a holistic CNN compression framework, termed LRDKT, which works throughout both convolutional and fully-connected layers. First, a low-rank decomposition (LRD) scheme is proposed to remove redundancies across both convolutional kernels and fullyconnected matrices, which has a novel closed-form solver to significantly improve the efficiency of the existing iterative optimization solvers. Second, a novel knowledge transfer (KT) based training scheme is introduced. To recover the accumulated accuracy loss and overcome the vanishing gradient, KT explicitly aligns outputs and intermediate responses from a teacher (original) network to its student (compressed) network. We have comprehensively analyzed and evaluated the compression and speedup ratios of the proposed model on MNIST and ILSVRC 2012 benchmarks. In both benchmarks, the proposed scheme has demonstrated superior performance gains over the state-of-the art methods. We also demonstrate the proposed compression scheme for the task of transfer learning, including domain adaptation and object detection, which show exciting performance gains over the state-of-the-arts. Our source code and compressed models are available at https://github.com/ShaohuiLin/LRDKT. PMID- 30281440 TI - Dynamic Atlas-based segmentation and quantification of Neuromelanin-rich brainstem structures in Parkinson disease. AB - We present a dynamic atlas composed of neuromelanin-enhanced magnetic resonance brain images of 40 healthy subjects. The performance of this atlas is evaluated on the fully automated segmentation of two paired neuromelanin-rich brainstem healthy structures: the substantia nigra pars compacta and the locus coeruleus. We show that our dynamic atlas requires in average 60% less images, and therefore 60% less computation time than a static multi-image atlas, while achieving similar segmentation performance. Then, we show that by applying our dynamic atlas, composed of healthy subjects, to the segmentation and neuromelanin quantification of a set of brain images of 39 Parkinson disease patients, we are able to find significant quantitative differences in the level of neuromelanin between healthy subjects and Parkinson disease patients, thus opening the door to the use of these structures as image biomarkers in future Computer Aided Diagnosis systems for the diagnosis of Parkinson disease. PMID- 30281441 TI - Accurate iterative FBP reconstruction method for material decomposition of dual energy CT. AB - Compared to traditional CT, dual energy CT (DECT) has the capability to improve material differentiation and reduce beam hardening artifacts, thus has wide prospects of applications. In this paper, by linearizing the polychromatic projections with their first order Taylor expansions, we derive an iterative reconstruction method for DECT. The method updates the basis material images by adding the residual images reconstructed from the residual projections to the current estimated basis material images, i.e., the iteration process of the proposed method is carried out in image domain, so it is applicable to both geometrically consistent and inconsistent projections. In addition, as the filtered back-projection (FBP) method is used in the reconstruction of the residual images, the proposed method has a high degree of parallelism. Both numerical simulation and real data experiments are performed, and the results confirm the effectiveness of the proposed reconstruction method. PMID- 30281442 TI - Portable Vector Flow Imaging Compared with Spectral Doppler Ultrasonography. AB - In this study, a vector flow imaging (VFI) method developed for a portable ultrasound scanner was used for estimating peak velocity values and variation in beam-to-flow angle over the cardiac cycle in vivo on healthy volunteers. Peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistive index (RI) measured with VFI were compared to spectral Doppler ultrasonography (SDU). Seventeen healthy volunteers were scanned on the left and right common carotid arteries (CCAs). The standard deviation (SD) of VFI measurements averaged over the cardiac cycle was 7.3% for the magnitude and 3.84 degrees for the angle. Bland-Altman plots showed a positive bias for the PSV measured with SDU (mean difference: 0.31ms-1), and Pearson correlation analysis showed a highly significant correlation (r = 0.6; p < 0.001). A slightly positive bias was found for EDV and RI measured with SDU (mean difference: 0.08ms-1 and -0.01ms-1, respectively). However, the correlation was low and not significant. The beam-to flow angle was estimated over the systolic part of the cardiac cycle, and its variations were for all measurements larger than the precision of the angle estimation. The range spanned deviations from -25.2 degrees (-6.0 SD) to 23.7 degrees (4.2 SD) with an average deviation from -15.5 degrees to 9.7 degrees . This can significantly affect PSV values measured by SDU as the beam-toflow angle is not constant and not aligned with the vessel surface. The study demonstrates that the proposed VFI method can be used in vivo for the measurement of PSV in the CCAs, and that angle variations across the cardiac cycle can lead to significant errors in SDU velocity estimates. PMID- 30281444 TI - Fast Segmentation of the Left Atrial Appendage in 3D Transesophageal Echocardiographic Images. AB - Left atrial appendage (LAA) has been generally described as "our most lethal attachment", being considered the major source of thromboembolism in patients with non-valvular atrial fibrillation. Currently, LAA occlusion can be offered as a treatment for these patients, obstructing the LAA through a percutaneously delivered device. Nevertheless, correct device sizing is not straightforward, requiring the manual analysis of peri-procedural images. This approach is sub optimal, time demanding and highly variable between experts, which can result in lengthy procedures and excess manipulations. In this article, a semi-automatic LAA segmentation technique for 3D transesophageal echocardiography (TEE) images is presented. Specifically, the proposed technique relies on a novel segmentation pipeline where a curvilinear blind-ended model is optimized through a double stage strategy: 1) fast contour evolution using global terms and 2) contour refinement based on regional energies. To reduce its computational cost, and thus make it more attractive to real interventions, the B-spline Explicit Active Surface framework was used. This novel method was evaluated in a clinical database of 20 patients. Manual analysis performed by two observers was used as ground truth. The 3D segmentation results corroborated the accuracy, robustness to the variation of the parameters and computationally attractiveness of the proposed method, taking approximately 14 seconds to segment the LAA with an average accuracy of ~0.9 mm. Moreover, a performance comparable to the inter observer variability was found. Finally, the advantages of the segmented model were evaluated while semi-automatically extracting the clinical measurements for device selection, showing a similar accuracy but with a higher reproducibility when compared to the current practice. Overall, the proposed segmentation method shows potential for an improved planning of LAA occlusion, demonstrating its added value for normal clinical practice. PMID- 30281443 TI - Soft-Tissue Aberration Correction for Histotripsy. AB - Acoustic aberrations caused by natural heterogeneities of biological soft tissue are a substantial problem for histotripsy, a therapeutic ultrasound technique that uses acoustic cavitation to mechanically fractionate and destroy unwanted target tissue without damaging surrounding tissue. These aberrations, primarily caused by sound speed variations, result in severe defocusing of histotripsy pulses, thereby decreasing treatment efficacy. The gold standard for aberration correction (AC) is to place a hydrophone at the desired focal location to directly measure phase aberrations, which is a method that is infeasible in vivo. We hypothesized that the acoustic cavitation emission (ACE) shockwaves from the initial expansion of inertially cavitating microbubbles generated by histotripsy can be used as a point source for AC. In this study, a 500-kHz, 112-element histotripsy phased array capable of transmitting and receiving ultrasound on all channels was used to acquire ACE shockwaves. These shockwaves were first characterized optically and acoustically. It was found that the shockwave pressure increases significantly as the source changes from a single bubble to a dense cavitation cloud. The first arrival of the shockwave received by the histotripsy array was from the outer-most cavitation bubbles located closest to the histotripsy array. Hydrophone and ACE AC methods were then tested on ex vivo porcine abdominal tissue samples. Without AC, the focal pressure is reduced by 49.7% through the abdominal tissue. The hydrophone AC approach recovered 55.5% of the lost pressure. Using the ACE AC method, over 20% of the lost pressure was recovered, and the array power required to induce cavitation was reduced by approximately 31.5% compared to without AC. These results supported our hypothesis that the ACE shockwaves coupled with a histotripsy array with transmit and receive capability can be used for AC for histotripsy through soft tissue. PMID- 30281445 TI - Directivity and Frequency-Dependent Effective Sensitive Element Size of a Reflectance-Based Fiber Optic Hydrophone: Predictions from Theoretical Models Compared with Measurements. AB - The goal of this work was to measure directivity of a reflectance-based fiber optic hydrophone at multiple frequencies and to compare it to four theoretical models: Rigid Baffle (RB), Rigid Piston (RP), Unbaffled (UB), and Soft Baffle (SB). The fiber had a nominal 105 MUm diameter core and a 125 MUm overall diameter (core + cladding). Directivity measurements were performed at 2.25, 3.5, 5, 7.5, 10, and 15 MHz from +/-90 degrees in two orthogonal planes. Effective hydrophone sensitive element radius was estimated by least-squares fitting the four models to directivity measurements using the sensitive element radius as an adjustable parameter. Over the range from 2.25 to 15 MHz, the average magnitudes of differences between the effective and nominal sensitive element radii were 59 +/- 49% (RB), 10 +/- 5% (RP), 46 +/- 38% (UB), and 71 +/- 19% (SB). Therefore, directivity of a reflectance-based fiber-optic hydrophone may be best estimated by the RP model. PMID- 30281446 TI - Sparse Doppler Sensing Based on Nested Arrays. AB - Spectral Doppler ultrasound imaging allows visualizing blood flow by estimating its velocity distribution over time. Duplex ultrasound is a modality in which an ultrasound system is used for displaying simultaneously both B-mode images and spectral Doppler data. In B-mode imaging short wide-band pulses are used to achieve sufficient spatial resolution in the images. In contrast, for Doppler imaging, narrow-band pulses are preferred in order to attain increased spectral resolution. Thus, the acquisition time must be shared between the two sequences. In this work, we propose a non-uniform slow-time transmission scheme for spectral Doppler, based on nested arrays, which reduces the number of pulses needed for accurate spectrum recovery. We derive the minimal number of Doppler emissions needed, using this approach, for perfect reconstruction of the blood spectrum in a noise-free environment. Next, we provide two spectrum recovery techniques which achieve this minimal number. The first method performs efficient recovery based on the fast Fourier transform. The second allows for continuous recovery of the Doppler frequencies, thus avoiding off-grid error leakage, at the expense of increased complexity. The performance of the techniques is evaluated using realistic Field II simulations as well as in vivo measurements, producing accurate spectrograms of the blood velocities using a significantly reduced number of transmissions. The time gained, where no Doppler pulses are sent, can be used to enable the display of both blood velocities and high quality B-mode images at a high frame rate. PMID- 30281447 TI - A Dual-frequency Co-linear Array for Acoustic Angiography in Prostate Cancer Evaluation. AB - Approximately 80% of men who reach 80-years of age will have some form of prostate cancer. The challenge remains to differentiate benign and malignant lesions. Based on recent research, acoustic angiography, a novel contrast enhanced ultrasound imaging technique, can provide high-resolution visualization of tissue microvasculature and has demonstrated the ability to differentiate vascular characteristics between healthy and tumor tissue in preclinical studies. We hypothesize that transrectal acoustic angiography may enhance the assessment of prostate cancer. In this paper, we describe the development of a dual frequency, dual-layer co-linear array transducer for transrectal acoustic angiography. The probe consists of 64 transmitting (TX) elements with a center frequency of 3 MHz and 128 receiving (RX) elements with a center frequency of 15 MHz. The dimensions of the array are 18 mm in azimuth and 9 mm in elevation. The pitch is 280 MUm for TX elements and 140 MUm for RX elements. Pulse-echo tests of TX/RX elements and aperture acoustic field measurements were conducted, and the both results were compared with simulation results. Real-time contrast imaging was performed using a Verasonics system and a tissue-mimicking phantom. Non linear acoustic responses from microbubble contrast agents at a depth of 35 mm were clearly observed. In-vivo imaging in a rodent model demonstrated the ability to detect individual vessels underneath the skin. These results indicate the potential use of the array described herein for acoustic angiography imaging of prostate tumor and identification of regions of neovascularization for the guidance of prostate biopsies. PMID- 30281448 TI - Learning Effective RGB-D Representations for Scene Recognition. AB - Deep convolutional networks (CNN) can achieve impressive results on RGB scene recognition thanks to large datasets such as Places. In contrast, RGB-D scene recognition is still underdeveloped in comparison, due to two limitations of RGB D data we address in this paper. The first limitation is the lack of depth data for training deep learning models. Rather than fine tuning or transferring RGB specific features, we address this limitation by proposing an architecture and a twostep training approach that directly learns effective depth-specific features using weak supervision via patches. The resulting RGBD model also benefits from more complementary multimodal features. Another limitation is the short range of depth sensors (typically 0.5m to 5.5m), resulting in depth images not capturing distant objects in the scenes that RGB images can. We show that this limitation can be addressed by using RGB-D videos, where more comprehensive depth information is accumulated as the camera travels across the scenes. Focusing on this scenario, we introduce the ISIA RGB-D video dataset to evaluate RGB-D scene recognition with videos. Our video recognition architecture combines convolutional and recurrent neural networks (RNNs) that are trained in three steps with increasingly complex data to learn effective features (i.e. patches, frames and sequences). Our approach obtains state-of-the-art performances on RGB D image (NYUD2 and SUN RGB-D) and video (ISIA RGB-D) scene recognition. PMID- 30281449 TI - Spectral Total-Variation Local Scale Signatures for Image Manipulation and Fusion. AB - We propose a unified framework for isolating, comparing and differentiating objects within an image. We rely on the recently proposed total-variation transform, yielding a continuous, multi-scale, fully edge-preserving, local descriptor, referred to as spectral total-variation local scale signatures. We show and analyze several useful merits of this framework. Signatures are sensitive to size, local contrast and composition of structures; are invariant to translation, rotation, flip and linear illumination changes; and texture signatures are robust to the underlying structures. We prove exact conditions in the 1D case. We propose several applications for this framework: saliency map extraction for fusion of thermal and optical images or for medical imaging, clustering of vein-like features and size-based image manipulation. PMID- 30281450 TI - A Probabilistic Approach to Cross-Region Matching-Based Image Retrieval. AB - With deep convolutional features, cross-region matching (CRM) has recently shown superior performance on image retrieval. It evaluates image similarity by comparing image regions at different locations and scales, and is, therefore, more robust to geometric variance of objects. This paper first scrutinizes CRM based image retrieval to provide a rigorous probabilistic interpretation by following the probability ranking principle. In addition to manifesting the assumptions implicitly taken by CRM, our interpretation highlights a fundamental issue hindering the performance of CRM-when comparing two image regions, CRM ignores modeling the distribution of the visual concept class associated with an image region, making the similarity comparison less precise. Taking advantage of the unprecedented representation capability of deep convolutional features, this paper proposes one approach to tackle that issue. It treats locally clustered image regions as a pseudo-labeled class sharing the same visual concept and utilizes them to model the distribution of the visual concept class associated with an image region. Both non-parametric and parametric methods are developed for this purpose, with careful probabilistic justification. Extensive experimental study on multiple benchmark data sets demonstrates the superior performance of the proposed pseudo-label approach to CRM and other comparable methods, with the maximum improvement of more than 10 percentage points over CRM.

AB - We present DeepISP, a full end-to-end deep neural model of the camera image signal processing (ISP) pipeline. Our model learns a mapping from the raw low light mosaiced image to the final visually compelling image and encompasses low level tasks such as demosaicing and denoising as well as higher-level tasks such as color correction and image adjustment. The training and evaluation of the pipeline were performed on a dedicated dataset containing pairs of low-light and well-lit images captured by a Samsung S7 smartphone camera in both raw and processed JPEG formats. The proposed solution achieves state-of-the-art performance in objective evaluation of PSNR on the subtask of joint denoising and demosaicing. For the full end-to-end pipeline, it achieves better visual quality compared to the manufacturer ISP, in both a subjective human assessment and when rated by a deep model trained for assessing image quality. PMID- 30281452 TI - Graph-Based Joint Dequantization and Contrast Enhancement of Poorly Lit JPEG Images. AB - JPEG images captured in poor lighting conditions suffer from both low luminance contrast and coarse quantization artifacts due to lossy compression. Performing dequantization and contrast enhancement in separate back-to-back steps would amplify the residual compression artifacts, resulting in low visual quality. Leveraging on recent development in graph signal processing (GSP), we propose to jointly dequantize and contrast-enhance such images in a single graph-signal restoration framework. Specifically, we separate each observed pixel patch into illumination and reflectance via Retinex theory, where we define generalized smoothness prior and signed graph smoothness prior according to their respective unique signal characteristics. Given only a transform-coded image patch, we compute robust edge weights for each graph via low-pass filtering in the dual graph domain. We compute the illumination and reflectance components for each patch alternately, adopting accelerated proximal gradient (APG) algorithms in the transform domain, with backtracking line search for further speedup. Experimental results show that our generated images outperform the state-of-the-art schemes noticeably in the subjective quality evaluation. PMID- 30281453 TI - Learning a Convolutional Neural Network for Image Compact-Resolution. AB - We study the dual problem of image super-resolution (SR), which we term image compact-resolution (CR). Opposite to image SR that hallucinates a visually plausible high-resolution image given a low-resolution input, image CR provides a low-resolution version of a high-resolution image, such that the low-resolution version is both visually pleasing and as informative as possible compared to the high-resolution image. We propose a convolutional neural network (CNN) for image CR, namely, CNN-CR, inspired by the great success of CNN for image SR. Specifically, we translate the requirements of image CR into operable optimization targets for training CNN-CR: the visual quality of the compact resolved image is ensured by constraining its difference from a naively downsampled version and the information loss of image CR is measured by upsampling/super-resolving the compact-resolved image and comparing that to the original image. Accordingly, CNN-CR can be trained either separately or jointly with a CNN for image SR. We explore different training strategies as well as different network structures for CNN-CR. Our experimental results show that the proposed CNN-CR clearly outperforms simple bicubic downsampling and achieves on average 2.25 dB improvement in terms of the reconstruction quality on a large collection of natural images. We further investigate two applications of image CR, i.e., low-bit-rate image compression and image retargeting. Experimental results show that the proposed CNN-CR helps achieve significant bits saving than High Efficiency Video Coding when applied to image compression and produce visually pleasing results when applied to image retargeting. PMID- 30281454 TI - Multi-Domain & Multi-Task Learning for Human Action Recognition. AB - Domain-invariant (view-invariant & modalityinvariant) feature representation is essential for human action recognition. Moreover, given a discriminative visual representation, it is critical to discover the latent correlations among multiple actions in order to facilitate action modeling. To address these problems, we propose a multi-domain & multi-task learning (MDMTL) method to (1) extract domain invariant information for multi-view and multi-modal action representation and (2) explore the relatedness among multiple action categories. Specifically, we present a sparse transfer learning-based method to co-embed multi-domain (multi view & multi-modality) data into a single common space for discriminative feature learning. Additionally, visual feature learning is incorporated into the multitask learning framework, with the Frobenius-norm regularization term and the sparse constraint term, for joint task modeling and task relatedness-induced feature learning. To the best of our knowledge, MDMTL is the first supervised framework to jointly realize domain-invariant feature learning and task modeling for multi-domain action recognition. Experiments conducted on the INRIA Xmas Motion Acquisition Sequences (IXMAS) dataset, the MSR Daily Activity 3D (DailyActivity3D) dataset, and the Multi-modal & Multi-view & Interactive (M2I) dataset, which is the most recent and largest multi-view and multi-model action recognition dataset, demonstrate the superiority of MDMTL over the state-of-the art approaches. PMID- 30281455 TI - MSFD: Multi-Scale Segmentation-Based Feature Detection for Wide-Baseline Scene Reconstruction. AB - A common problem in wide-baseline matching is the sparse and non-uniform distribution of correspondences when using conventional detectors, such as SIFT, SURF, FAST, A-KAZE, and MSER. In this paper, we introduce a novel segmentation based feature detector (SFD) that produces an increased number of accurate features for wide-baseline matching. A multi-scale SFD is proposed using bilateral image decomposition to produce a large number of scale-invariant features for wide-baseline reconstruction. All input images are over-segmented into regions using any existing segmentation technique, such as Watershed, Mean shift, and simple linear iterative clustering. Feature points are then detected at the intersection of the boundaries of three or more regions. The detected feature points are local maxima of the image function. The key advantage of feature detection based on segmentation is that it does not require global threshold setting and can, therefore, detect features throughout the image. A comprehensive evaluation demonstrates that SFD gives an increased number of features that are accurately localized and matched between wide-baseline camera views; the number of features for a given matching error increases by a factor of 3-5 compared with SIFT; feature detection and matching performance are maintained with increasing baseline between views; multi-scale SFD improves matching performance at varying scales. Application of SFD to sparse multi-view wide baseline reconstruction demonstrates a factor of 10 increases in the number of reconstructed points with improved scene coverage compared with SIFT/MSER/A-KAZE. Evaluation against ground-truth shows that SFD produces an increased number of wide-baseline matches with a reduced error. PMID- 30281456 TI - Zero-Shot Learning via Category-Specific Visual-Semantic Mapping and Label Refinement. AB - Zero-Shot Learning (ZSL) aims to classify a test instance from an unseen category based on the training instances from seen categories, in which the gap between seen categories and unseen categories is generally bridged via visual-semantic mapping between the low-level visual feature space and the intermediate semantic space. However, the visual-semantic mapping (i.e., projection) learnt based on seen categories may not generalize well to unseen categories, which is known as the projection domain shift in ZSL. To address this projection domain shift issue, we propose a method named Adaptive Embedding ZSL (AEZSL) to learn an adaptive visual-semantic mapping for each unseen category, followed by progressive label refinement. Moreover, to avoid learning visual-semantic mapping for each unseen category in the large-scale classification task, we additionally propose a deep adaptive embedding model named Deep AEZSL (DAEZSL) sharing the similar idea (i.e., visual-semantic mapping should be category-specific and related to the semantic space) with AEZSL, which only needs to be trained once, but can be applied to arbitrary number of unseen categories. Extensive experiments demonstrate that our proposed methods achieve the state-of-theart results for image classification on three small-scale benchmark datasets and one large-scale benchmark dataset. PMID- 30281457 TI - Deep Convolutional Neural Network for Natural Image Matting Using Initial Alpha Mattes. AB - We propose a deep convolutional neural network (CNN) method for natural image matting. Our method takes multiple initial alpha mattes of the previous methods and normalized RGB color images as inputs, and directly learns an end-to-end mapping between the inputs and reconstructed alpha mattes. Among the various existing methods, we focus on using two simple methods as initial alpha mattes: the closed-form matting and KNN matting. They are complementary to each other in terms of local and nonlocal principles. A major benefit of our method is that it can "recognize" different local image structures and then combine the results of local (closed-form matting) and nonlocal (KNN matting) mattings effectively to achieve higher quality alpha mattes than both of the inputs. Furthermore, we verify extendability of the proposed network to different combinations of initial alpha mattes from more advanced techniques such as KL divergence matting and information-flow matting. On the top of deep CNN matting, we build an RGB guided JPEG artifacts removal network to handle JPEG block artifacts in alpha matting. Extensive experiments demonstrate that our proposed deep CNN matting produces visually and quantitatively high-quality alpha mattes. We perform deeper experiments including studies to evaluate the importance of balancing training data and to measure the effects of initial alpha mattes and also consider results from variant versions of the proposed network to analyze our proposed DCNN matting. In addition, our method achieved high ranking in the public alpha matting evaluation dataset in terms of the sum of absolute differences, mean squared errors, and gradient errors. Also, our RGB guided JPEG artifacts removal network restores the damaged alpha mattes from compressed images in JPEG format. PMID- 30281458 TI - Context-Aware Text-Based Binary Image Stylization and Synthesis. AB - In this work, we present a new framework for the stylization of text-based binary images. First, our method stylizes the stroke-based geometric shape like text, symbols and icons in the target binary image based on an input style image. Second, the composition of the stylized geometric shape and a background image is explored. To accomplish the task, we propose legibilitypreserving structure and texture transfer algorithms, which progressively narrow the visual differences between the binary image and the style image. The stylization is then followed by a contextaware layout design algorithm, where cues for both seamlessness and aesthetics are employed to determine the optimal layout of the shape in the background. Given the layout, the binary image is seamlessly embedded into the background by texture synthesis under a context-aware boundary constraint. According to the contents of binary images, our method can be applied to many fields.We show that the proposed method is capable of addressing the unsupervised text stylization problem and is superior to stateof- the-art style transfer methods in automatic artistic typography creation. Besides, extensive experiments on various tasks, such as visual-textual presentation synthesis, icon/symbol rendering and structure-guided image inpainting, demonstrate the effectiveness of the proposed method. PMID- 30281459 TI - A Task-based Taxonomy of Cognitive Biases for Information Visualization. AB - Information visualization designers strive to design data displays that allow for efficient exploration, analysis, and communication of patterns in data, leading to informed decisions. Unfortunately, human judgment and decision making are imperfect and often plagued by cognitive biases. There is limited empirical research documenting how these biases affect visual data analysis activities. Existing taxonomies are organized by cognitive theories that are hard to associate with visualization tasks. Based on a survey of the literature we propose a task-based taxonomy of154 cognitive biases organized in 7 main categories. We hope the taxonomy will help visualization researchers relate their design to the corresponding possible biases, and lead to new research that detects and addresses biased judgment and decision making in data visualization. PMID- 30281460 TI - BRDF Analysis with Directional Statistics and Its Applications. AB - Data-driven BRDF models using real material measurements have become increasingly prevalent due to the development of novel gonioreflectometers, but efficient use of these models in many graphical applications remains challenging due to the few functionalities the raw data could provide. To ameliorate this issue, we propose to analyze BRDFs using directional statistics for better handling and exploring measured materials, especially isotropic materials, with efficient computation and compact storage. We conduct a thorough statistical analysis on both analytical BRDF models and measured materials from the MERL database. We show that different aspects of visual appearance can be characterized by different spherical moments, from which several descriptive measures can be derived to further facilitate their usage. We demonstrate how these measures are best leveraged in some graphical applications including gamut mapping using a new BRDF similarity measure, BRDF or SVBRDF reconstruction based on material clustering, and importance sampling for measured materials based on fast extracted GGX distributions. We finally show the potential of our approach in the categorization of surface reflectance types which is common for traditional photon mapping. PMID- 30281461 TI - ViSeq: Visual Analytics of Learning Sequence in Massive Open Online Courses. AB - The research on massive open online courses (MOOCs) data analytics has mushroomed recently because of the rapid development of MOOCs. The MOOC data not only contains learner profiles and learning outcomes, but also sequential information about when and which type of learning activities each learner performs, such as reviewing a lecture video before undertaking an assignment. Learning sequence analytics could help understand the correlations between learning sequences and performances, which further characterize different learner groups. However, few works have explored the sequence of learning activities, which have mostly been considered aggregated events. A visual analytics system called ViSeq is introduced to resolve the loss of sequential information, to visualize the learning sequence of different learner groups, and to help better understand the reasons behind the learning behaviors. The system facilitates users in exploring learning sequences from multiple levels of granularity. ViSeq incorporates four linked views: the projection view to identify learner groups, the pattern view to exhibit overall sequential patterns within a selected group, the sequence view to illustrate the transitions between consecutive events, and the individual view with an augmented sequence chain to compare selected personal learning sequences. Case studies and expert interviews were conducted to evaluate the system. PMID- 30281462 TI - Topic-based Exploration and Embedded Visualizations for Research Idea Generation. AB - This work analyzes sensemaking frameworks and experiments with an iteratively designed visual analysis tool to identify design implications for facilitating research idea generation using visualizations. Our tool, ThoughtFlow, structures and visualizes literature collections using topic models to bridge the information gap between core activities during research ideation. To help users stay focused on a topic while discovering relevant documents, we designed and analyzed usage patterns for two types of embedded visualization that help determine document relevance while minimizing distraction. We analyzed how research ideation outcomes and processes differ when using ThoughtFlow and conventional search engines by augmenting insight-based evaluation with concept map analysis. Our results suggest that operations afforded by topic models match well with later ideation stages when coherent topics have emerged, but not with early stages when users are still relying heavily on individual keywords to gather background knowledge. We also present qualitative evidence that citation sparklines encourage more exploration of recommended references, and that a preference for paper thumbnails may depend on the consistency between the evidence and the current mental frame. PMID- 30281463 TI - A Novel CNN-based Poisson Solver for Fluid Simulation. AB - Solving a large-scale Poisson system is computationally expensive for most of the Eulerian fluid simulation applications. We propose a novel machine learning-based approach to accelerate this process. At the heart of our approach is a deep convolutional neural network (CNN), with the capability of predicting the solution (pressure) of a Poisson system given the discretization structure and the intermediate velocities as input. Our system consists of four main components, namely, a deep neural network to solve the large linear equations, a geometric structure to describe the spatial hierarchies of the input vector, a Principal Component Analysis (PCA) process to reduce the dimension of input in training, and a novel loss function to control the incompressibility constraint. We have demonstrated the efficacy of our approach by simulating a variety of high resolution smoke and liquid phenomena. In particular, we have shown that our approach accelerates the projection step in a conventional Eulerian fluid simulator by two orders of magnitude. In addition, we have also demonstrated the generality of our approach by producing a diversity of animations deviating from the original datasets. PMID- 30281464 TI - Comparison of Convolutive Kernel Compensation and Non-Negative Matrix Factorization of Surface Electromyograms. AB - We compared non-negative matrix factorization (NMF) and convolution kernel compensation techniques for high-density electromyogram decomposition. The experimental data were recorded from nine healthy persons during controlled single degree of freedom (DOF) wrist flexion-extension, supination-pronation, and ulnar-radial deviation movements. We assembled the identified motor units and NMF components into three groups. Those active mostly during the first and the second movement direction per DOF were placed in the G1 and G3 groups, respectively. The remaining components were nonspecific for movement direction and were placed in the G2 group. In ulnar and radial deviation, the relative energies of identified cumulative motor unit spike trains (CSTs) and NMF components were similarly distributed among the groups. In other two movement types, the energy of NMF components in the G2 group was significantly larger than the energy of CSTs. We further performed a coherence analysis between CSTs and sums of NMF components in each group. Both decompositions demonstrated a solid match, but only at frequencies <3 Hz. At higher frequencies, the coherence hardly exceeded the value of 0.5. Potential reasons for these discrepancies include the negative impact of motor unit action potential shapes and noise on NMF decomposition. PMID- 30281465 TI - A Fatigue Involved Modification Framework for Force Estimation in Fatiguing Contraction. AB - To alleviate the negative impacts of muscle fatigue on a force estimation model, a modification framework taking use of fatigue index was put forward in this paper. Muscle force and surface electromyography were first collected using high density electrode grid and dynamometer. Then, multi-step signal pre-processing and a nonnegative matrix factorization-based signal optimization were conducted, with fatigue indices being extracted in the same time. Next, a degree 4 polynomial fitting model was employed to undertake the training process, and the relationship between the generated model parameters and fatigue indices was built up. In the end, the parameter-index relationship was applied on different testing sets to complete fatigue-modified force estimation. Significant improvement was found in most testing cases across different sexes and ages. Relative decreases of 36.5%, 20.7%, and 20.4% in the percentage root mean square error were achieved by young males, young females, and elderly males. The proposed method can boost the performances of force estimation models, thereby contributing to the development of a variety of fields including biomechanical study, rehabilitation treatment, and prosthesis research. PMID- 30281466 TI - Reducing the Energy Cost of Human Running Using an Unpowered Exoskeleton. AB - In this paper, we present a new perspective to design an unpowered exoskeleton for metabolic rate reduction in running. According to our studies on human biomechanics, it was observed that having a torsional spring that applies torque as a linear function of the difference between two hips angles ( -angle), compared with a local spring which applies torque as a function of hip angle ( angle), provides a better condition for hip moment compensation and, consequently, metabolic rate reduction. Accordingly, a new type of unpowered exoskeleton device for realization of this idea was designed, and a prototype of this exoskeleton was constructed. This exoskeleton was tested on 10 healthy active subjects for running at 2.5 m s-1. In this experiment, 8.0 +/- 1.5% (mean +/- s.e.m.) metabolic rate reduction (compared with the no-exoskeleton case) was achieved. PMID- 30281467 TI - STEW: Simultaneous Task EEG Workload Data Set. AB - This paper describes an open access electroencephalography (EEG) data set for multitasking mental workload activity induced by a single-session simultaneous capacity (SIMKAP) experiment with 48 subjects. To validate the database, EEG spectral activity was evaluated with EEGLAB and the significant channels and activities for the experiment are highlighted. Classification performance was evaluated by training a support vector regression model on selected features from neighborhood component analysis based on a nine-point workload rating scale. With a reduced feature dimension, 69% classification accuracy was obtained for 3 identified workload levels from the rating scale with Cohen's kappa of 0.46. Accurate discrimination of mental workload is a desirable outcome in the field of operator performance analysis and BCI development; thus, we hope that our provided database and analyses can contribute to future investigations in this research field. PMID- 30281468 TI - simBCI - A framework for studying BCI methods by simulated EEG. AB - Brain-Computer Interface (BCI) methods are commonly studied using Electroencephalogram (EEG) data recorded from human experiments. For understanding and developing BCI signal processing techniques real data is costly to obtain and its composition is apriori unknown. The brain mechanisms generating the EEG are not directly observable and their states cannot be uniquely identified from the EEG. Subsequently, we do not have generative ground truth for real data. In this paper we propose a novel convenience framework called simBCI to alleviate testing and studying BCI signal processing methods in simulated, controlled conditions. The framework can be used to generate artificial BCI data and to test classification pipelines with such data. Models and parameters on both data generation and the signal processing side can be iterated over to examine the interplay of different combinations. The framework provides the first time open source implementations of several models and methods. We invite researchers to insert more advanced models. The proposed system does not intend to replace human experiments. Instead, it can be used to discover hypotheses, study algorithms, to educate about BCI, and to debug signal processing pipelines of other BCI systems. The proposed framework is modular, extensible and freely available as open source1. It currently requires Matlab. PMID- 30281469 TI - A Modeling Procedure of the Broadband Dielectric Spectroscopy for Ionic Liquids. AB - The dielectric spectroscopy (DS) measurement is an attractive noninvasive method to reveal the intrinsic information of biological materials and cell cultures. However, the presence of a double layer due to electrode polarization within the lower RF and microwave range significantly affects the accurate analysis of dielectric properties of ionic liquids. In this paper, we measure the broadband DS of five saline solutions with a microfluidic coplanar waveguide (CPW) transmission line sensor across the frequency range from 40 kHz to 110 GHz. Derived from a parallel-plate structure that is transformed from the quasi-TEM CPW sensor through a conformal mapping technique, a broadband spectroscopy modeling method is proposed, where a Cole-Cole function or a constant phase element formula is used depending on the ionic concentrations and the measurement window. Validation analysis on the five saline solutions demonstrates the capability of the modeling method in separating relaxation properties of the bulk sample from the double-layer effects. PMID- 30281470 TI - Modeling and Dynamic Behavior of eIF2 Dependent Regulatory System With Disturbances. AB - Eukaryotic initiation factor 2 (eIF2) is a central controller of the eukaryotic translational machinery. To sustain the on-going translation activity, eIF2 cycles between its GTP and GDP bound states. However, in response to cellular stresses, the phosphorylation of eIF2 takes place, which acts as an inhibitor of the guanine nucleotide exchange factor eIF2B and switches the translation activity on physiological timescales. The main objective of this paper is to investigate the stability of the regulatory system under nominal conditions, parametric fluctuations, and structural damages. In this paper, a mathematical model of eIF2-dependent regulatory system is used to identify the stability conferring features within the system with the help of direct and indirect methods of Lyapunov stability theory. To investigate the impact of intrinsic fluctuations and structural damages on the stability of regulatory system, the mathematical model has been linearized around feasible equilibrium point and the variation of system poles has been observed. The investigations have revealed that the regulatory model is stable and able to tolerate the intrinsic stressors but becomes unstable when particular complex is targeted to override the undesirable interaction. Our analyses indicate that, the stability is a collective property and damage in the structure of the system changes the stability of the system. PMID- 30281471 TI - A Parallel Workflow Pattern Modeling Using Spiking Neural P Systems With Colored Spikes. AB - Spiking neural P systems, otherwise known as named SN P systems, are bio-inspired parallel and distributed neural-like computing models. Due to the spiking behavior, SN P systems fall into the category of spiking neural networks, and are considered to be an auspicious candidate of the 3G of neural networks. It has been reported that SN P systems with colored spikes are computationally capable, and perform well in describing behaviors of complex systems. Nonetheless, some practical issue is open to be investigate, such as workflow and traffic flow modeling. In this paper, a parallel workflow pattern modeling using SN P systems with colored spikes is proposed. As results, 20 designs are constructed using SN P systems for 20 classical workflow patterns. The functioning processes that operate both sequentially and simultaneously in the workflow pattern are able to be modeled and simulated. SN P systems with colored spikes have some similarity with Petri nets, hence can be used to model workflow patterns. This will provide a novel neural-like modeling method for modeling traffic flow. PMID- 30281472 TI - ASAPP: Architectural Similarity-based Automated Pathway Prediction System and its Application in Host-Pathogen Interactions. AB - The significance of metabolic pathway prediction is to envision the viable unknown transformations that can occur provided the appropriate enzymes are present. It can facilitate the prediction of the consequences of host-pathogen interactions. In this article, we have proposed a new algorithm ASAPP (Architectural Similarity-based Automated Pathway Prediction) to predict metabolic pathways based on the structural similarity among the metabolites. ASAPP takes two dimensional structure and molecular weight of metabolites as input, and generates a list of probable transformations without the knowledge of any externally established reactions, with an accuracy of 85.09%. ASAPP has also been applied to predict the outcome of pathogen liberated toxins on the carbohydrate and lipid pathways of the hosts. We have analyzed the disruption of host pathways in the presence of toxins, and have found that some metabolites in Glycolysis and the TCA cycle have a high chance of being the breakpoints in the pathway. The tool is available at http://asapp.droppages.com/. PMID- 30281473 TI - In Silico Design and Experimental Validation of Combination Therapy for Pancreatic Cancer. AB - The number of deaths associated with Pancreatic Cancer has been on the rise in the United States making it an especially dreaded disease. The overall prognosis for pancreatic cancer patients continues to be grim because of the complexity of the disease at the molecular level involving the potential activation/inactivation of several diverse signaling pathways. In this paper, we first model the aberrant signaling in pancreatic cancer using a multi-fault Boolean Network. Thereafter, we theoretically evaluate the efficacy of different drug combinations by simulating this boolean network with drugs at the relevant intervention points and arrive at the most effective drug(s) to achieve cell death. The simulation results indicate that drug combinations containing Cryptotanshinone, a traditional Chinese herb derivative, result in considerably enhanced cell death. These in silico results are validated using wet lab experiments we carried out on Human Pancreatic Cancer (HPAC) cell lines. PMID- 30281474 TI - Inferring disease-associated microRNAs in heterogeneous networks with node attributes. AB - Identification of disease-associated microRNAs (disease miRNAs) is an essential step towards discovering causal miRNAs and understanding disease pathogenesis. Two sources of information can be exploited for predicting disease miRNAs: one includes the connections between miRNAs, between diseases, and between miRNAs and diseases, and the other has the attributes of miRNA nodes. The former contains information of miRNA similarities, disease similarities, and miRNA-disease associations. The latter includes the information of the families and clusters that miRNAs belong to. Similar diseases are usually associated with miRNAs that have similar functions and common attributes. However, most of the existing methods for disease miRNA prediction focus only on the connections of miRNAs and diseases. It remains challenging to adequately integrate the connections and miRNA node attributes to identify more reliable candidate disease miRNAs. We propose a non-negative matrix factorization based method, FamCluRank, for predicting disease miRNAs in heterogeneous networks with node attributes. One of the novelties of FamCluRank is to fully utilize these two oversighted characteristics of miRNAs and focuses particularly on a deep integration of miRNA families and cluster attributes. In particular, the integration was achieved by three different means. We first constructed a miRNA-disease heterogeneous network with node attributes where the miRNA nodes have their family and cluster attributes. Second, miRNAs sharing more common families and clusters are more likely to be associated with the diseases that are also related to these families and clusters. On the basis of the biological premise, we constructed a novel prediction model of FamCluRank to deeply integrate the family and cluster attributes of miRNAs. Third, two similar diseases tend to be associated with more common miRNA families and clusters, and vice versa. Hence FamCluRank's prediction model is constructed by concerning not only the possible associations between miRNAs and diseases but also the possible disease-family and disease-cluster associations. Comparison with the state-of-the-art methods showed FamCluRank's superior performance not only on the well-characterized diseases but also on the new ones. Case studies on colorectal neoplasms, pancreatic neoplasms, lung neoplasms, and 32 new diseases demonstrated its ability for discovering potential disease miRNAs. FamCluRank is a potent prioritization tool for screening the reliable candidates for subsequent studies concerning their involvement in the pathogenesis of diseases. The web service of FamCluRank, the candidate disease miRNAs for 329 diseases, and the dataset used to develop FamCluRank are available at http://www.famclurank.top. PMID- 30281475 TI - Enhancing of Particle Swarm Optimization Based Method for Multiple Motifs Detection in DNA Sequences Collections. AB - Genome sequence data consists of DNA sequences or input sequences. Each one includes nucleotides with chemical structures presented as characters: 'A', 'C', 'G', and 'T', and groups of motif sequences, called Transcription Factor Binding Sites (TFBSs), which are subsequences of DNA that lead to protein-synthesis. The detection of TFBSs is an important problem for bioinformatics research. With the similar patterns of motif sequences in TFBSs, computational algorithms for TFBSs detection have been improved to reduce resources used in laboratory setting. The metaheuristic algorithm is the important issue that has been continually improved to detect TFBSs with greater precision and recall. This paper proposes PSO_HD by applying Particle Swarm Optimization (PSO) as a pre-process and using Hamming distance to improve the efficiency of detecting TFBSs with more precision and recall. In order to measure its efficiency, the paper compares the TFBSs detection using PSO_HD algorithm with relevant algorithms in 8 datasets. F-score is used as a measurement unit and compared to the related algorithms. The experimental results show that PSO_HD algorithm gives the highest average F score, which can be indicated that the PSO_HD algorithm can improve the efficiency of detecting TFBSs with more precision and recall.

PMID- 30281476 TI - Gene Regulatory Relationship Mining Using Improved Three-Phase Dependency Analysis Approach. AB - How to mine the gene regulatory relationship and construct gene regulatory network (GRN) is of utmost interest within the whole biological community, however, which has been consistently a challenging problem since the tremendous complexity in cellular systems. In present work, we construct gene regulatory network using an improved three-phase dependency analysis algorithm (TPDA) Bayesian network learning method, which includes the steps of Drafting, Thickening and Thinning. In order to solve the problem of learning result is not reliable due to the high order conditional independence test, we use the entropy estimation approach of Gaussian kernel probability density estimator to calculate the (conditional) mutual information between genes. The experiment on the public benchmark data sets show the improved method outperforms other 9 kinds of Bayesian network learning methods when to process the data with large sample size, with small number of discrete values, and the frequency of different discrete values is about same. In addition, the improved TPDA method was further applied on a real large gene expression data set on RNA-seq from a global collection with 368 elite maize inbred lines. Experiment results show it performs better than the original TPDA method and other 9 kinds of Bayesian network learning algorithms significantly. PMID- 30281478 TI - miRTRS: A Recommendation Algorithm for Predicting miRNA Targets. AB - microRNAs (miRNAs) are small and important non-coding RNAs that regulate gene expression in transcriptional and post-transcriptional level by combining with their targets(genes). Predicting miRNA targets is an important problem in biological research. It is expensive and time-consuming to identify miRNA targets by using biological experiments. Many computational methods have been proposed to predict miRNA targets. However, these methods suffer from the high false positive rate because of the complex relationships between miRNAs and their targets. In this study, we develop a novel method, named miRTRS, for predicting miRNA targets based on a recommendation algorithm. miRTRS can predict targets for an isolated(new) miRNA with miRNA sequence similarity, as well as isolated(new) targets for a miRNA with gene sequence similarity. Furthermore, comparing to supervised machine learning methods, miRTRS does not need to select negative samples. We use ten-fold cross validation and independent datasets to evaluate the performance of our method. The experimental results have shown that our method miRTRS outperforms other miRNA target prediction methods in terms of AUC and other evaluation metrics.

AB - Tele-manipulation of heavy loads typically requires the simultaneous use of two asymmetric slaves: a crane for vertical weight support; and a robot for accurate lateral positioning. The industrial standard prescribes a pair of operators for such tasks (one operator to control each slave), although in principle one operator might control both slaves with a single, hybrid interface. Accurate and safe co-operative handling of the expensive and fragile heavy components is difficult, presumably due to problems in the coordination of the subtasks and the lack of mutual awareness between the two operators. This study proposes a novel haptic assistance system to improve subtask coordination and task performance. Its novelty consists of haptically linking operators/interfaces through the joint task environment. The system's efficacy is evaluated with fifteen pairs of co operators and fifteen individual uni-manual operators who manoeuvred a heavy load through a bounded path in Virtual Reality. Haptic assistance improves task completion time for both groups. It also reduces control activity and self reported workload without affecting a number of critical errors made by the operators. Moreover, without haptic assistance, uni-manual operators perform worse than co-operators, but this difference between the interfaces disappears with haptic assistance. PMID- 30281480 TI - Evaluation of Skin Deformation Tactile Feedback for Teleoperated Surgical Tasks. AB - During interaction with objects using a tool, we experience force and tactile feedback. One form of tactile feedback is local fingerpad skin deformation. In this paper, we provide haptic feedback to users of a teleoperation system through a skin deformation tactile feedback device. The device is able to provide tangential and normal skin deformation in a coupled manner, and is designed so that users can grasp it with a precision grip using multiple fingerpads. By applying skin deformation feedback on multiple fingerpads, the device is able to provide multi-degree-of-freedom interaction force direction and magnitude information to the user. To evaluate the effectiveness of this approach for the performance of teleoperated manipulation tasks, we performed a study in which 20 participants used a teleoperation system to perform one of two manipulation tasks (peg transfer and tube connection) using force feedback, skin deformation feedback, and the combination of both feedback. Results showed that participants are able to use all feedback to improve task performance compared to the case without haptic feedback, although the degree of improvement depended on the nature of the task. The feedback also improved situation awareness, felt consistent with prior experience, and did not affect concentration on the task, as reported by participants. PMID- 30281481 TI - Output-Feedback Adaptive Neural Controller for Uncertain Pure-Feedback Nonlinear Systems Using a High-Order Sliding Mode Observer. AB - A novel adaptive neural output-feedback controller for SISO nonaffine pure feedback nonlinear systems is proposed. The majority of the previously described adaptive neural controllers for pure-feedback nonlinear systems were based on the dynamic surface control (DSC) or backstepping schemes. This makes the control law as well as the stability analysis highly lengthy and complicated. Moreover, there has been very limited research till date on the output-feedback neural controller for this class of the systems. The proposed controller evades adopting adaptive backstepping or DSC scheme through reformulating the original system into the Brunovsky form, which considerably simplifies the control law. Combining a high order sliding mode observer and single radial-basis function network with universal approximation property, it is shown that the controller guarantees closed-loop system stability in the Lyapunov sense. PMID- 30281482 TI - Pool-Based Sequential Active Learning for Regression. AB - Active learning (AL) is a machine-learning approach for reducing the data labeling effort. Given a pool of unlabeled samples, it tries to select the most useful ones to label so that a model built from them can achieve the best possible performance. This paper focuses on pool-based sequential AL for regression (ALR). We first propose three essential criteria that an ALR approach should consider in selecting the most useful unlabeled samples: informativeness, representativeness, and diversity, and compare four existing ALR approaches against them. We then propose a new ALR approach using passive sampling, which considers both the representativeness and the diversity in both the initialization and subsequent iterations. Remarkably, this approach can also be integrated with other existing ALR approaches in the literature to further improve the performance. Extensive experiments on 11 University of California, Irvine, Carnegie Mellon University StatLib, and University of Florida Media Core data sets from various domains verified the effectiveness of our proposed ALR approaches. PMID- 30281483 TI - Feature Analysis of Marginalized Stacked Denoising Autoenconder for Unsupervised Domain Adaptation. AB - Marginalized stacked denoising autoencoder (mSDA), has recently emerged with demonstrated effectiveness in domain adaptation. In this paper, we investigate the rationale for why mSDA benefits domain adaptation tasks from the perspective of adaptive regularization. Our investigations focus on two types of feature corruption noise: Gaussian noise (mSDAg) and Bernoulli dropout noise (mSDAbd). Both theoretical and empirical results demonstrate that mSDAbd successfully boosts the adaptation performance but mSDAg fails to do so. We then propose a new mSDA with data-dependent multinomial dropout noise (mSDAmd) that overcomes the limitations of mSDAbd and further improves the adaptation performance. Our mSDAmd is based on a more realistic assumption: different features are correlated and, thus, should be corrupted with different probabilities. Experimental results demonstrate the superiority of mSDAmd to mSDAbd on the adaptation performance and the convergence speed. Finally, we propose a deep transferable feature coding (DTFC) framework for unsupervised domain adaptation. The motivation of DTFC is that mSDA fails to consider the distribution discrepancy across different domains in the feature learning process. We introduce a new element to mSDA: domain divergence minimization by maximum mean discrepancy. This element is essential for domain adaptation as it ensures the extracted deep features to have a small distribution discrepancy. The effectiveness of DTFC is verified by extensive experiments on three benchmark data sets for both Bernoulli dropout noise and multinomial dropout noise. PMID- 30281484 TI - On the Representational Power of Restricted Boltzmann Machines for Symmetric Functions and Boolean Functions. AB - Restricted Boltzmann machines (RBMs) are used to build deep-belief networks that are widely thought to be one of the first effective deep learning neural networks. This paper studies the ability of RBMs to represent distributions over {0,1}^n via softplus/hardplus RBM networks. It is shown that any distribution whose density depends on the number of 1's in their input can be approximated with arbitrarily high accuracy by an RBM of size 2n+1, which improves the result of a previous study by reducing the size from n2 to 2n+1. A theorem for representing partially symmetric Boolean functions by softplus RBM networks is established. Accordingly, the representational power of RBMs for distributions whose mass represents the Boolean functions is investigated in comparison with that of threshold circuits and polynomial threshold functions. It is shown that a distribution over {0,1}^n whose mass represents a Boolean function can be computed with a given margin delta by an RBM of size and parameters bounded by polynomials in n, if and only if it can be computed by a depth-2 threshold circuit with size and parameters bounded by polynomials in n. PMID- 30281485 TI - Quantized Minimum Error Entropy Criterion. AB - Comparing with traditional learning criteria, such as mean square error, the minimum error entropy (MEE) criterion is superior in nonlinear and non-Gaussian signal processing and machine learning. The argument of the logarithm in Renyi's entropy estimator, called information potential (IP), is a popular MEE cost in information theoretic learning. The computational complexity of IP is, however, quadratic in terms of sample number due to double summation. This creates the computational bottlenecks, especially for large-scale data sets. To address this problem, in this paper, we propose an efficient quantization approach to reduce the computational burden of IP, which decreases the complexity from O( N2 ) to O( MN ) with M ll N. The new learning criterion is called the quantized MEE (QMEE). Some basic properties of QMEE are presented. Illustrative examples with linear-in parameter models are provided to verify the excellent performance of QMEE. PMID- 30281486 TI - Stochastic Conjugate Gradient Algorithm With Variance Reduction. AB - Conjugate gradient (CG) methods are a class of important methods for solving linear equations and nonlinear optimization problems. In this paper, we propose a new stochastic CG algorithm with variance reduction and we prove its linear convergence with the Fletcher and Reeves method for strongly convex and smooth functions. We experimentally demonstrate that the CG with variance reduction algorithm converges faster than its counterparts for four learning models, which may be convex, nonconvex or nonsmooth. In addition, its area under the curve performance on six large-scale data sets is comparable to that of the LIBLINEAR solver for the L2-regularized L2-loss but with a significant improvement in computational efficiency. PMID- 30281487 TI - Hierarchical Feature Selection for Random Projection. AB - Random projection is a popular machine learning algorithm, which can be implemented by neural networks and trained in a very efficient manner. However, the number of features should be large enough when applied to a rather large scale data set, which results in slow speed in testing procedure and more storage space under some circumstances. Furthermore, some of the features are redundant and even noisy since they are randomly generated, so the performance may be affected by these features. To remedy these problems, an effective feature selection method is introduced to select useful features hierarchically. Specifically, a novel criterion is proposed to select useful neurons for neural networks, which establishes a new way for network architecture design. The testing time and accuracy of the proposed method are improved compared with traditional methods and some variations on both classification and regression tasks. Extensive experiments confirm the effectiveness of the proposed method. PMID- 30281488 TI - Generalized Uncorrelated Regression with Adaptive Graph for Unsupervised Feature Selection. AB - Unsupervised feature selection always occupies a key position as a preprocessing in the tasks of classification or clustering due to the existence of extra essential features within high-dimensional data. Although lots of efforts have been made, the existing methods neglect to consider the redundancy of features, and thus select redundant features. In this brief, by virtue of a generalized uncorrelated constraint, we present an improved sparse regression model [generalized uncorrelated regression model (GURM)] for seeking the uncorrelated yet discriminative features. Benefited from this, the structure of data is kept in the Stiefel manifold, which avoids the potential trivial solution triggered by a conventional ridge regression model. Besides that, the uncorrelated constraint equips the model with the closed-form solution. In addition, we also incorporate a graph regularization term based on the principle of maximum entropy into the GURM model (URAFS), so as to embed the local geometric structure of data into the manifold learning. An efficient algorithm is designed to perform URAFS by virtue of the existing generalized powered iteration method. Extensive experiments on eight benchmark data sets among seven state-of-the-art methods on the task of clustering are conducted to verify the effectiveness and superiority of the proposed method. PMID- 30281489 TI - Heterogeneous Domain Adaptation Through Progressive Alignment. AB - In real-world transfer learning tasks, especially in cross-modal applications, the source domain and the target domain often have different features and distributions, which are well known as the heterogeneous domain adaptation (HDA) problem. Yet, existing HDA methods focus on either alleviating the feature discrepancy or mitigating the distribution divergence due to the challenges of HDA. In fact, optimizing one of them can reinforce the other. In this paper, we propose a novel HDA method that can optimize both feature discrepancy and distribution divergence in a unified objective function. Specifically, we present progressive alignment, which first learns a new transferable feature space by dictionary-sharing coding, and then aligns the distribution gaps on the new space. Different from previous HDA methods that are limited to specific scenarios, our approach can handle diverse features with arbitrary dimensions. Extensive experiments on various transfer learning tasks, such as image classification, text categorization, and text-to-image recognition, verify the superiority of our method against several state-of-the-art approaches. PMID- 30281490 TI - Bounded Neural Network Control for Target Tracking of Underactuated Autonomous Surface Vehicles in the Presence of Uncertain Target Dynamics. AB - This paper is concerned with the target tracking of underactuated autonomous surface vehicles with unknown dynamics and limited control torques. The velocity of the target is unknown, and only the measurements of line-of-sight range and angle are obtained. First, a kinematic control law is designed based on an extended state observer, which is utilized to estimate the uncertain target dynamics due to the unknown velocities. Next, an estimation model based on a single-hidden-layer neural network is developed to approximate the unknown follower dynamics induced by uncertain model parameters, unmodeled dynamics, and environmental disturbances. A bounded control law is designed based on the neural estimation model and a saturated function. The salient feature of the proposed controller is twofold. First, only the measured line-of-sight range and angle are used, and the velocity information of the target is not required. Second, the control torques are bounded with the bounds known as a priori. The input-to-state stability of the closed-loop system is analyzed via cascade theory. Simulations illustrate the effectiveness of the proposed bounded controller for tracking a moving target. PMID- 30281491 TI - Generalization and Expressivity for Deep Nets. AB - Along with the rapid development of deep learning in practice, theoretical explanations for its success become urgent. Generalization and expressivity are two widely used measurements to quantify theoretical behaviors of deep nets. The expressivity focuses on finding functions expressible by deep nets but cannot be approximated by shallow nets with similar number of neurons. It usually implies the large capacity. The generalization aims at deriving fast learning rate for deep nets. It usually requires small capacity to reduce the variance. Different from previous studies on deep nets, pursuing either expressivity or generalization, we consider both the factors to explore theoretical advantages of deep nets. For this purpose, we construct a deep net with two hidden layers possessing excellent expressivity in terms of localized and sparse approximation. Then, utilizing the well known covering number to measure the capacity, we find that deep nets possess excellent expressive power (measured by localized and sparse approximation) without essentially enlarging the capacity of shallow nets. As a consequence, we derive near-optimal learning rates for implementing empirical risk minimization on deep nets. These results theoretically exhibit advantages of deep nets from the learning theory viewpoint. PMID- 30281492 TI - Bag-Level Aggregation for Multiple-Instance Active Learning in Instance Classification Problems. AB - A growing number of applications, e.g., video surveillance and medical image analysis, require training recognition systems from large amounts of weakly annotated data, while some targeted interactions with a domain expert are allowed to improve the training process. In such cases, active learning (AL) can reduce labeling costs for training a classifier by querying the expert to provide the labels of most informative instances. This paper focuses on AL methods for instance classification problems in multiple instance learning (MIL), where data are arranged into sets, called bags, which are weakly labeled. Most AL methods focus on single-instance learning problems. These methods are not suitable for MIL problems because they cannot account for the bag structure of data. In this paper, new methods for bag-level aggregation of instance informativeness are proposed for multiple instance AL (MIAL). The aggregated informativeness method identifies the most informative instances based on classifier uncertainty and queries bags incorporating the most information. The other proposed method, called cluster-based aggregative sampling, clusters data hierarchically in the instance space. The informativeness of instances is assessed by considering bag labels, inferred instance labels, and the proportion of labels that remain to be discovered in clusters. Both proposed methods significantly outperform reference methods in extensive experiments using benchmark data from several application domains. Results indicate that using an appropriate strategy to address MIAL problems yields a significant reduction in the number of queries needed to achieve the same level of performance as single-instance AL methods. PMID- 30281493 TI - Temporal Attention-Augmented Bilinear Network for Financial Time-Series Data Analysis. AB - Financial time-series forecasting has long been a challenging problem because of the inherently noisy and stochastic nature of the market. In the high-frequency trading, forecasting for trading purposes is even a more challenging task, since an automated inference system is required to be both accurate and fast. In this paper, we propose a neural network layer architecture that incorporates the idea of bilinear projection as well as an attention mechanism that enables the layer to detect and focus on crucial temporal information. The resulting network is highly interpretable, given its ability to highlight the importance and contribution of each temporal instance, thus allowing further analysis on the time instances of interest. Our experiments in a large-scale limit order book data set show that a two-hidden-layer network utilizing our proposed layer outperforms by a large margin all existing state-of-the-art results coming from much deeper architectures while requiring far fewer computations. PMID- 30281494 TI - Multiobjective Support Vector Machines: Handling Class Imbalance With Pareto Optimality. AB - Support vector machines (SVMs) seek to optimize three distinct objectives: maximization of margin, minimization of regularization from the positive class, and minimization of regularization from the negative class. The right choice of weightage for each of these objectives is critical to the quality of the classifier learned, especially in case of the class imbalanced data sets. Therefore, costly parameter tuning has to be undertaken to find a set of suitable relative weights. In this brief, we propose to train SVMs, on two-class as well as multiclass data sets, in a multiobjective optimization framework called radial boundary intersection to overcome this shortcoming. The experimental results suggest that the radial boundary intersection-based scheme is indeed effective in finding the best tradeoff among the objectives compared with parameter-tuning schemes. PMID- 30281495 TI - Face Sketch Synthesis by Multidomain Adversarial Learning. AB - Given a training set of face photo-sketch pairs, face sketch synthesis targets at learning a mapping from the photo domain to the sketch domain. Despite the exciting progresses made in the literature, it retains as an open problem to synthesize high-quality sketches against blurs and deformations. Recent advances in generative adversarial training provide a new insight into face sketch synthesis, from which perspective the existing synthesis pipelines can be fundamentally revisited. In this paper, we present a novel face sketch synthesis method by multidomain adversarial learning (termed MDAL), which overcomes the defects of blurs and deformations toward high-quality synthesis. The principle of our scheme relies on the concept of ''interpretation through synthesis.'' In particular, we first interpret face photographs in the photodomain and face sketches in the sketch domain by reconstructing themselves respectively via adversarial learning. We define the intermediate products in the reconstruction process as latent variables, which form a latent domain. Second, via adversarial learning, we make the distributions of latent variables being indistinguishable between the reconstruction process of the face photograph and that of the face sketch. Finally, given an input face photograph, the latent variable obtained by reconstructing this face photograph is applied for synthesizing the corresponding sketch. Quantitative comparisons to the state-of-the-art methods demonstrate the superiority of the proposed MDAL method. PMID- 30281496 TI - Deep Semantic-Preserving Ordinal Hashing for Cross-Modal Similarity Search. AB - Cross-modal hashing has attracted increasing research attention due to its efficiency for large-scale multimedia retrieval. With simultaneous feature representation and hash function learning, deep cross-modal hashing (DCMH) methods have shown superior performance. However, most existing methods on DCMH adopt binary quantization functions (e.g., sign(.)) to generate hash codes, which limit the retrieval performance since binary quantization functions are sensitive to the variations of numeric values. Toward this end, we propose a novel end-to end ranking-based hashing framework, in this paper, termed as deep semantic preserving ordinal hashing (DSPOH), to learn hash functions with deep neural networks by exploring the ranking structure of feature dimensions. In DSPOH, the ordinal representation, which encodes the relative rank ordering of feature dimensions, is explored to generate hash codes. Such ordinal embedding benefits from the numeric stability of rank correlation measures. To make the hash codes discriminative, the ordinal representation is expected to well predict the class labels so that the ranking-based hash function learning is optimally compatible with the label predicting. Meanwhile, the intermodality similarity is preserved to guarantee that the hash codes of different modalities are consistent. Importantly, DSPOH can be effectively integrated with different types of network architectures, which demonstrates the flexibility and scalability of our proposed hashing framework. Extensive experiments on three widely used multimodal data sets show that DSPOH outperforms state of the art for cross-modal retrieval tasks. PMID- 30281497 TI - Distributed Adaptive Tracking Synchronization for Coupled Reaction-Diffusion Neural Network. AB - This paper considers the tracking synchronization problem for a class of coupled reaction-diffusion neural networks (CRDNNs) with undirected topology. For the case where the tracking trajectory has identical individual dynamic as that of the network nodes, the edge-based and vertex-based adaptive strategies on coupling strengths as well as adaptive controllers, which demand merely the local neighbor information, are proposed to synchronize the CRDNNs to the tracking trajectory. To reduce the control costs, an adaptive pinning control technique is employed. For the case where the tracking trajectory has different individual dynamic from that of the network nodes, the vertex-based adaptive strategy is proposed to drive the synchronization error to a relatively small area, which is adjustable according to the parameters of the adaptive strategy. This kind of adaptive design can enhance the robustness of the network against the external disturbance posed on the tracking trajectory. The obtained theoretical results are verified by two representative examples. PMID- 30281498 TI - Deep Neural Network Initialization With Decision Trees. AB - In this paper, a novel, automated process for constructing and initializing deep feedforward neural networks based on decision trees is presented. The proposed algorithm maps a collection of decision trees trained on the data into a collection of initialized neural networks with the structures of the networks determined by the structures of the trees. The tree-informed initialization acts as a warm-start to the neural network training process, resulting in efficiently trained, accurate networks. These models, referred to as ''deep jointly informed neural networks'' (DJINN), demonstrate high predictive performance for a variety of regression and classification data sets and display comparable performance to Bayesian hyperparameter optimization at a lower computational cost. By combining the user-friendly features of decision tree models with the flexibility and scalability of deep neural networks, DJINN is an attractive algorithm for training predictive models on a wide range of complex data sets. PMID- 30281499 TI - Nonuniformly Sampled Data Processing Using LSTM Networks. AB - We investigate classification and regression for nonuniformly sampled variable length sequential data and introduce a novel long short-term memory (LSTM) architecture. In particular, we extend the classical LSTM network with additional time gates, which incorporate the time information as a nonlinear scaling factor on the conventional gates. We also provide forward-pass and backward-pass update equations for the proposed LSTM architecture. We show that our approach is superior to the classical LSTM architecture when there is correlation between time samples. In our experiments, we achieve significant performance gains with respect to the classical LSTM and phased-LSTM architectures. In this sense, the proposed LSTM architecture is highly appealing for the applications involving nonuniformly sampled sequential data. PMID- 30281500 TI - Neuroimaging Retrieval via Adaptive Ensemble Manifold Learning for Brain Disease Diagnosis. AB - Alzheimer's disease (AD) is a neurodegenerative and non-curable disease, with serious cognitive impairment, such as dementia. Clinically, it is critical to study the disease with multi-source data in order to capture a global picture of it. In this respect, an adaptive ensemble manifold learning (AEML) algorithm is proposed to retrieve multi-source neuroimaging data. Specifically, an objective function based on manifold learning is formulated to impose geometrical constraints by similarity learning. The complementary characteristics of various sources of brain disease data for disorder discovery are investigated by tuning weights from ensemble learning. In addition, a generalized norm is explicitly explored for adaptive sparseness degree control. The proposed AEML algorithm is evaluated by the public Alzheimer's disease neuroimaging initiative (ADNI) database. Results obtained from the extensive experiments demonstrate that our algorithm outperforms the traditional methods. PMID- 30281501 TI - Simultaneous Volumetric Segmentation of Vertebral Bodies and Intervertebral Discs on Fat-Water MR Images. AB - Fat-water magnetic resonance (MR) images allow automated noninvasive analysis of morphological properties and fat fractions of vertebral bodies (VBs) and intervertebral discs (IVDs) that constitute an important part of human biomechanical systems. In this paper, we propose a fully automated approach for simultaneously segmenting multiple VBs and IVDs on fat-water MR images without prior localization or geometry estimation. This method involved a hierarchical random forest (HRF) classifier and a hierarchical conditional random field (HCRF) that encoded amulti-resolution image pyramid based on a set of multiscale local and contextual features. The HRF classifier employed penalized multivariate linear discriminants and SMOTEBagging to handle limited and imbalanced training data with large feature dimension. The HCRF estimated optimum labels according to their spatial and hierarchical consistencies by using the layer-wise significant features determined over the trained HRF classifier. To handle variable sample numbers at different resolutions, resolutionspecific hyperparameters were used. This method was trained and evaluated for segmenting 15 thoracic and lumbar VBs and their IVDs on fat-water MR images of a subset of a large cohort data set. It was further evaluated for segmenting 7 IVDs of the lower spine on fat-water images of a public grand challenge. These evaluations revealed the comparable accuracy of this method with the state-ofthe-art while requiring less computational burden due to a simultaneous localization and segmentation. PMID- 30281502 TI - A hybrid feature selection method based on binary state transition algorithm and ReliefF. AB - Feature selection problems often appear in the application of data mining, which have been difficult to handle due to the NP-hard property of these problems. In this study, a simple but efficient hybrid feature selection method is proposed based on binary state transition algorithm (BSTA) and ReliefF, called ReliefF BSTA. This method contains two phases: the filter phase and the wrapper phase. There are three aspects of advantages in this method. First, an initialization approach based on feature ranking is designed to make sure that the initial solution is not easy to get tapped into local optimum. Then a probability substitute operator based on feature weights is developed to update the current solution according to the different mutation probabilities of the features. Finally, a new selection strategy based on relative dominance is presented to find the current best solution. The simple and efficient algorithm -Nearest Neighborhood (-NN) with the leave-one-out cross validation is used as a classifier to evaluate feature subset candidates. The experimental results indicate that the proposed method is more efficient in terms of the classification accuracy through a comparison to other feature selection methods using seven public datasets and several real biomedical datasets. For public datasets, the proposed method improved the classification average accuracy by about 2.5% compared with the filter method. For a specific biomedical dataset AID1284, the classification accuracy significantly increased from 77.24% to 85.25% by using the proposed method. PMID- 30281503 TI - A Three-stage Deep Learning Model for Accurate Retinal Vessel Segmentation. AB - Automatic retinal vessel segmentation is a fundamental step in the diagnosis of eye-related diseases, in which both thick vessels and thin vessels are important features for symptom detection. All existing deep learning models attempt to segment both types of vessels simultaneously by using a unified pixelwise loss which treats all vessel pixels with equal importance. Due to the highly imbalanced ratio between thick vessels and thin vessels (namely the majority of vessel pixels belong to thick vessels), the pixel-wise loss would be dominantly guided by thick vessels and relatively little influence comes from thin vessels, often leading to low segmentation accuracy for thin vessels. To address the imbalance problem, in this paper, we explore to segment thick vessels and thin vessels separately by proposing a three-stage deep learning model. The vessel segmentation task is divided into three stages, namely thick vessel segmentation, thin vessel segmentation and vessel fusion. As better discriminative features could be learned for separate segmentation of thick vessels and thin vessels, this process minimizes the negative influence caused by their highly imbalanced ratio. The final vessel fusion stage refines the results by further identifying non-vessel pixels and improving the overall vessel thickness consistency. The experiments on public datasets DRIVE, STARE and CHASE DB1 clearly demonstrate that the proposed threestage deep learning model outperforms the current state-of theart vessel segmentation methods. PMID- 30281504 TI - Kinematic and Kinetic Validation of an Improved Depth Camera Motion Assessment System Using Rigid Bodies. AB - The study of joint kinematics and dynamics has broad clinical applications including the identification of pathological motions or compensation strategies and the analysis of dynamic stability. High-end motion capture systems, however, are expensive and require dedicated camera spaces with lengthy set-up and data processing commitments. Depth cameras, such as the Microsoft Kinect, provide an inexpensive, marker-free alternative at the sacrifice of joint-position accuracy. In this work, we present a fast framework for adding biomechanical constraints to the joint estimates provided by a depth camera system. We also present a new model for the lower lumbar joint angle. We validate key joint position, angle, and velocity measurements against a gold standard active motion-capture system on ten healthy subjects performing sit-to-stand (STS). Our method showed significant improvement in Mean Absolute Error and Intraclass Correlation Coefficients for the recovered joint angles and position-based metrics. These improvements suggest that depth cameras can provide an accurate and clinically viable method of rapidly assessing the kinematics and kinetics of the STS action, providing data for further analysis using biomechanical or machine learning methods. PMID- 30281505 TI - Distributed Hinfinity Estimation in Sensor Networks With Two-Channel Stochastic Attacks. AB - This paper is concerned with the distributed estimation problem in sensor networks subjected to unknown attacks. Network attacks are considered to exist in two classes of channels: 1) communication channels from the plant to sensors and 2) communication channels among sensors. The status of an attack is viewed as a stochastic phenomenon, and the transmitted information will be affected when the attacker successfully carries out an attack on the related data packet. Based on the sensors' own measurements and their neighbors' local information, a novel distributed estimation model against two-channel stochastic attacks is presented. A sufficient condition on the existence of the desired distributed Hinfinity estimators is derived and the distributed estimator gains are designed by solving a linear matrix inequality. Two illustrative examples are provided to demonstrate the effectiveness of the new design techniques. PMID- 30281506 TI - Visual Tracking and Depth Estimation of Mobile Robots Without Desired Velocity Information. AB - In this paper, a visual servoing approach is developed for the trajectory tracking control and depth estimation problem of a mobile robot without a priori knowledge about desired velocities. By exploiting the multiple images captured by the on-board camera, the current and desired poses (i.e., scaled translation and orientation) of the mobile robot are reconstructed to define system errors. Then, an adaptive time-varying controller is proposed to achieve the trajectory tracking task in the presence of nonholonomic constraint and unknown depth parameters. Most of previous works require the measurement of the desired velocity information to facilitate the controller design, leading to tedious offline computation. In this paper, to eliminate this requirement, the desired velocities are estimated in real-time based on a reduced order observer. Moreover, an augmented update law is designed to compensate for the unknown depth parameters and identify the inverse depth constant. The Lyapunov-based method is employed to prove that the proposed controller achieves asymptotic tracking, and the inverse depth estimate converges to its actual value provided that a persistent excitation condition is satisfied. Subsequently, a robust data-driven algorithm is introduced to ensure the convergence of the inverse depth estimate under a relaxed finite excitation condition. Simulation and experimental results are provided to demonstrate the effectiveness of the proposed approach. PMID- 30281507 TI - R$2$BN: An Adaptive Model for Keystroke-Dynamics-Based Educational Level Classification. AB - Over the past decade, keystroke-based pattern recognition techniques, as a forensic tool for behavioral biometrics, have gained increasing attention. Although a number of machine learning-based approaches have been proposed, they are limited in terms of their capability to recognize and profile a set of an individual's characteristics. In addition, up to today, their focus was primarily gender and age, which seem to be more appropriate for commercial applications (such as developing commercial software), leaving out from research other characteristics, such as the educational level. Educational level is an acquired user characteristic, which can improve targeted advertising, as well as provide valuable information in a digital forensic investigation, when it is known. In this context, this paper proposes a novel machine learning model, the randomized radial basis function network, which recognizes and profiles the educational level of an individual who stands behind the keyboard. The performance of the proposed model is evaluated by using the empirical data obtained by recording volunteers' keystrokes during their daily usage of a computer. Its performance is also compared with other well-referenced machine learning models using our keystroke dynamic datasets. Although the proposed model achieves high accuracy in educational level prediction of an unknown user, it suffers from high computational cost. For this reason, we examine ways to reduce the time that is needed to build our model, including the use of a novel data condensation method, and discuss the tradeoff between an accurate and a fast prediction. To the best of our knowledge, this is the first model in the literature that predicts the educational level of an individual based on the keystroke dynamics information only. PMID- 30281508 TI - Hyper-Laplacian Regularized Multilinear Multiview Self-Representations for Clustering and Semisupervised Learning. AB - In this paper, we address the multiview nonlinear subspace representation problem. Traditional multiview subspace learning methods assume that the heterogeneous features of the data usually lie within the union of multiple linear subspaces. However, instead of linear subspaces, the data feature actually resides in multiple nonlinear subspaces in many real-world applications, resulting in unsatisfactory clustering performance. To overcome this, we propose a hyper-Laplacian regularized multilinear multiview self-representation model, which is referred to as HLR-M2VS, to jointly learn multiple views correlation and a local geometrical structure in a unified tensor space and view-specific self representation feature spaces, respectively. In unified tensor space, a well founded tensor low-rank regularization is adopted to impose on the self representation coefficient tensor to ensure global consensus among different views. In view-specific feature space, hypergraph-induced hyper-Laplacian regularization is utilized to preserve the local geometrical structure embedded in a high-dimensional ambient space. An efficient algorithm is then derived to solve the optimization problem of the established model with theoretical convergence guarantee. Furthermore, the proposed model can be extended to semisupervised classification without introducing any additional parameters. An extensive experiment of our method is conducted on many challenging datasets, where a clear advance over state-of-the-art multiview clustering and multiview semisupervised classification approaches is achieved.

AB - Batch-mode active learning algorithms can select a batch of valuable unlabeled samples to manually annotate for reducing the total cost of labeling every unlabeled sample. To facilitate selection of valuable unlabeled samples, many batch-mode active learning algorithms map samples to the reproducing kernel Hilbert space induced by a radial-basis function (RBF) kernel. Setting a proper value to the parameter for the RBF kernel is crucial for such batch-mode active learning algorithms. In this paper, for automatic tuning of the kernel parameter, a hypothesis-margin-based criterion function is proposed. Three frameworks are also developed to incorporate the function of automatic tuning of the kernel parameter with existing batch-model active learning algorithms. In the proposed frameworks, the kernel parameter can be tuned in a single stage or in multiple stages. Tuning the kernel parameter in a single stage aims for the kernel parameter to be suitable for selecting the specified number of unlabeled samples. When the kernel parameter is tuned in multiple stages, the incorporated active learning algorithm can be enforced to make coarse-to-fine evaluations of the importance of unlabeled samples. The proposed framework can also improve the scalability of existing batch-mode active learning algorithms satisfying a decomposition property. Experimental results on data sets comprising hundreds to hundreds of thousands of samples have shown the feasibility of the proposed framework. PMID- 30281510 TI - Adaptive Fuzzy Control of Stochastic Nonlinear Systems With Fuzzy Dead Zones and Unmodeled Dynamics. AB - This paper focuses on an input-to-state practical stability problem for a class of stochastic nonlinear systems with unmodeled dynamics and fuzzy dead zones. A feasible adaptive fuzzy control method is proposed for the developed stochastic system with the slope of dead zone being certain or fuzzy. Based on stochastic small-gain theorem and backstepping technique, the closed-loop system is guaranteed to be input-state-practically stable in probability. The main contributions of this paper lie in that the considered system is more general, and the modified Lemma 2 makes the presentation of the formulas in lemma consistent with their application forms. Finally, two simulation examples are provided to demonstrate the effectiveness of the proposed approach. PMID- 30281511 TI - Mitochondria-Driven Elimination of Cancer and Senescent Cells. AB - Mitochondria and oxidative phosphorylation (OXPHOS) are emerging as intriguing targets for efficient elimination of cancer cells. The specificity of this approach is aided by the capacity of non-proliferating non-cancerous cells to withstand oxidative insult induced by OXPHOS inhibition. Recently we discovered that mitochondrial targeting can also be employed to eliminate senescent cells, where it breaks the interplay between OXPHOS and ATP transporters that appear important for the maintenance of mitochondrial morphology and viability in the senescent setting. Hence, mitochondria/OXPHOS directed pharmacological interventions show promise in several clinically-relevant scenarios that call for selective removal of cancer and senescent cells. PMID- 30281512 TI - The frequency of testing for glycated haemoglobin, HbA1c, is linked to the probability of achieving target levels in patients with suboptimally controlled diabetes mellitus. AB - Background We previously showed, in patients with diabetes, that >50% of monitoring tests for glycated haemoglobin (HbA1c) are outside recommended intervals and that this is linked to diabetes control. Here, we examined the effect of tests/year on achievement of commonly utilised HbA1c targets and on HbA1c changes over time. Methods Data on 20,690 adults with diabetes with a baseline HbA1c of >53 mmol/mol (7%) were extracted from Clinical Biochemistry Laboratory records at three UK hospitals. We examined the effect of HbA1c tests/year on (i) the probability of achieving targets of <=53 mmol/mol (7%) and <=48 mmol/mol (6.5%) in a year using multi-state modelling and (ii) the changes in mean HbA1c using a linear mixed-effects model. Results The probabilities of achieving <=53 mmol/mol (7%) and <=48 mmol/mol (6.5%) targets within 1 year were 0.20 (95% confidence interval: 0.19-0.21) and 0.10 (0.09-0.10), respectively. Compared with four tests/year, having one test or more than four tests/year were associated with lower likelihoods of achieving either target; two to three tests/year gave similar likelihoods to four tests/year. Mean HbA1c levels were higher in patients who had one test/year compared to those with four tests/year (mean difference: 2.64 mmol/mol [0.24%], p<0.001). Conclusions We showed that >=80% of patients with suboptimal control are not achieving commonly recommended HbA1c targets within 1 year, highlighting the major challenge facing healthcare services. We also demonstrated that, although appropriate monitoring frequency is important, testing every 6 months is as effective as quarterly testing, supporting international recommendations. We suggest that the importance HbA1c monitoring frequency is being insufficiently recognised in diabetes management.

AB - In recent years, Philip Morris International (PMI) launched a global rebranding strategy to expand the reach of Marlboro. Using a mixed-methods design, this study evaluated the appeal and influence of Marlboro advertising among Filipino youth. Six hundred and twenty-three adolescents aged 13-17 years old in Metro Manila participated in a survey, including three advertising conditions: two for Marlboro and one for Mighty, a local cigarette brand. One-way repeated measures analysis of variance (ANOVA) and paired t-tests evaluated differences between the three conditions on participants' attitudes toward advertisements [measured as identification, likeability, and perceived effectiveness (PE)]. Compared to Mighty, never-smokers rated Marlboro advertisements as more identifiable and likeable. Comparing by smoking status (never vs. ever), multivariable logistic regression assessed the influence of these attitudes on intention to smoke. Increased likeability was associated with greater intention to smoke among never smokers, and greater PE increased odds of intention to smoke for both never- and ever-smokers. Additionally, six focus group discussions (FGD) explored responses to campaign messaging. Themes were compared within and across groups. Marlboro was also appealing to FGD participants, who described the ads as attractive to youth and promoting "adventure" and "freedom", whereas the Mighty brand was seen as being for adults and current smokers. Our findings illustrate that Marlboro advertisements are distinctly appealing to youth. Marlboro rhetoric - where consumers are urged to "decide" to "Be Marlboro" - was particularly powerful. These findings support the need for addressing gaps in policies regulating the marketing and promotion of tobacco in the Philippines. PMID- 30281514 TI - Review of thiamine deficiency disorders: Wernicke encephalopathy and Korsakoff psychosis. AB - Wernicke encephalopathy (WE) and Korsakoff psychosis (KP), together termed Wernicke-Korsakoff syndrome (WKS), are distinct yet overlapping neuropsychiatric disorders associated with thiamine deficiency. Thiamine pyrophosphate, the biologically active form of thiamine, is essential for multiple biochemical pathways involved in carbohydrate utilization. Both genetic susceptibilities and acquired deficiencies as a result of alcoholic and non-alcoholic factors are associated with thiamine deficiency or its impaired utilization. WKS is underdiagnosed because of the inconsistent clinical presentation and overlapping of symptoms with other neurological conditions. The identification and individualized treatment of WE based on the etiology is vital to prevent the development of the amnestic state associated with KP in genetically predisposed individuals. Through this review, we bring together the existing data from animal and human models to expound the etiopathogenesis, diagnosis, and therapeutic interventions for WE and KP.

PMID- 30281517 TI - Difficulties in the dietary management of a girl with two diseases requiring a special diet. AB - 3-Methylcrotonylglycinuria (3-MCG) is an autosomal recessive inborn error of leucine metabolism caused by the deficiency of 3-methylocrotonyl-CoA carboxylase (3-MCC deficiency). It is the most commonly detected organic aciduria in newborn screening conducted by tandem mass spectrometry (MS/MS) [1, 2]. The clinical phenotype is heterogeneous, ranging from asymptomatic to acute metabolic decompensations [3, 4]. Although at least in severe cases and in acute life threatening episodes limiting natural protein intake (particularly leucine) together with high caloric intake during catabolic periods is required, the need for specific dietary management often seems questionable [2]. In contrast with the 3-MCC deficiency, in diabetes mellitus type 1 (DM1) a diet based on carbohydrate and protein-fat exchangers is beyond dispute. However, as DM1 is quite a common disease, it may occur in a single patient with a rare disease, such as 3-MCC deficiency.

PMID- 30281519 TI - Factors affecting the differentiation of the Apgar score and the biochemical correlation of fetal well-being - a prospective observational clinical study. AB - OBJECTIVE: Objective: The purpose of the study was to identify the features of both the labor and the assisting physicians when evaluating the newborn according to the Apgar score and how these correlate with the biochemical markers of fetal well-being in order to make the Apgar score more objective. PATIENTS AND METHODS: Material and methods: A prospective observational clinical study conducted in a 3rd reference level center between 1st April 2014 and 31st March 2015. The study enrolled 17 neonatologists and 1527 term newborns. RESULTS: Results: The Apgar score is highest after natural vaginal delivery, lower after instrumental labor (p <0.001). The pH of the umbilical cord blood and lactate concentration correlate better with a high score than with a lowered one. The young age of a physician does not reduce Apgar score reliability. There were no differences in Apgar assessment according to physicians' training and the time of labor. There were no correlations between abnormalities in postnatal central nervous system ultrasound and the Apgar score. CONCLUSION: Conclusion: Biochemical tests of umbilical cord blood significantly increase the Apgar score reliability. PMID- 30281520 TI - [Development in the first year of life of newborns born prematurely - preliminary report]. AB - OBJECTIVE: Introduction: Premature babies account for almost 7% of all newborns and the number of extremely premature infants is increasing. In the European Parliament the problem of premature birth was identified as a priority health task as early as 2011. It is emphasized that the problems of a premature newborn do not end with discharge from hospital. Objective: The aim of the paper was a tentative analysis of the development level of infants born before the 37th week of intrauterine life, taking into account various areas of development and searching for differences in the levels of the development of newborns born prematurely and on time. PATIENTS AND METHODS: Material and methods: The research covered two groups of babies: group I - infants born prematurely (between the 25th and 36th week of their intrauterine life) examined in their 11.5-12.5 month, group II - infants born in due time, examined in their 11.5-12.5 month. Evaluation was carried out in accordance with the Munich Functional Developmental Diagnostics. The analysis comprised 50 questionnaires of prematurely born babies and 30 infants born in due time. Gross and fine motor skills were assessed, as well as autonomy and perception. RESULTS: Results: In our general evaluation, 80% of the children from group I were active in accordance with their birth age. However, as regards the analysis of development in particular areas, 50% of the children from group I undertook activity compliant with their birth age. The analysis of average values indicates the relationship between the level of prematurity and the level of activity presented by the children examined. As the level of prematurity increases, the level of activity presented by the children decreases. The greatest difficulties in group I were noted with regards to perception and autonomy. CONCLUSION: Conclusions: The level of activity presented by the children born prematurely at the age of 12 months depends on their level of prematurity. Newborn babies who were born prematurely require diagnostics specifying different spheres of development.

The correct formation of the stomatognathic system is a result of the correct organization of the motor patterns during feeding. PMID- 30281522 TI - Early complications of extracorporeal shockwave lithotripsy in the records of the Department of Paediatrics, Nephrology and Allergology of the Military Institute of Medicine - preliminary results. AB - The aim of the study was to analyse the frequency and type of early complications of extracorporeal shock wave lithotripsy (ESWL) and to assess the safety of the procedure among paediatric patients. The study is a retrospective analysis of all ESWL procedures carried out due to urolithiasis in 2009-2015 in the Department of Paediatrics, Nephrology and Allergology of the Military Institute of Medicine. Medical records of 170 children were analysed: 94 girls (55.3%) and 76 boys (44.7%) aged 1 to 18 years. Out of the 272 procedures performed, 247 were included in the study. Among 233 effective ESWL treatments, complications were noted in 35 (15.02%) procedures: among 10 girls (40%) and 15 boys (60%). In 25 cases (10.73%) surgical intervention was necessary due to urinary obstruction caused by a fragment of a disintegrated stone. Urinary tract infection was present among 3 patients (1.29%) who required surgical treatment. Nonsurgical complications included 7 urinary tract infections (3%) and 3 cases of severe abdominal pain (1.29%). Complications such as perirenal haematoma, subcapsular haematoma or ureteral perforation were not observed. The vast majority of complications observed in the study were associated with urinary obstruction caused by partial blockage of the ureter with kidney stone fragments ("steinstrasse"). Despite the complications that were documented, ESWL should be considered a safe procedure. PMID- 30281523 TI - Pathophysiology and symptoms of renal colic in children - a case report. AB - Urolithiasis is a disease characterized by the presence of stones in the kidney or urinary tract. It is often detected accidentally during an ultrasound or an abdominal x-ray performed for other reasons. However, the first symptom of kidney stone disease can be severe pain called renal colic. Pain caused by a colic attack is characterized by sudden onset. In half of the cases it is associated with nausea or vomiting and can lead to hypotension and fainting. The exact location and radiation of the pain depends on the location of the stone in the urinary tract. The first most commonly performed study is abdominal ultrasound with estimation of the deposit size and evaluation of urinary tract obstruction. Alternative or complementary studies are: an abdominal x-ray where radiopaque deposits can be shown, or unenhanced helical computed tomography of the abdomen. The severity of pain depends on the individual pain threshold and on the change in hydrostatic pressure in the part of the urinary system above the obstruction. Prolonged deposition of the stone in one place causes the activation of autoregulatory mechanisms to lower the pressure of the upper urinary tract, which limits the pain. The basic treatment for renal colic is analgetic therapy. The most commonly used drugs are NSAIDs and opiates. Another important component of renal colic treatment are medications that facilitate urinary stone passage by reducing oedema or limiting urethral contractions, such as: calcium channel blockers, alpha blockers, phosphodiesterase inhibitors. Intensive hydration is not currently recommended. Patients who are unlikely to spontaneously excrete the stone are eligible for minimally invasive treatment. The risk of urolithiasis recurring is high, reaching up to 40% in 5 years and up to 50% in 10 years. However, it can be reduced by proper prevention. The paper describes the pathophysiology of pain in renal colic, the treatment methods, and the case of a boy with recurrent renal colic.

AB - The role of prenatal cardiology and the organization of perinatal cardiological centers in early diagnostics and early therapeutic procedures in fetuses and newborns with cardiac malformations and circulatory disturbances was discussed on the basis of the literature and own experience. The possibilities of an early perinatal diagnosis and early therapeutic approaches to cardiac defects were presented. It was stressed that there is a necessity to broaden the educational aims in these areas and in the near future to prepare multidisciplinary teams working together in specialist centers.

AB - The characteristics of chordomas in children are distinct from those in adults. In particular, the prognosis of patients with INI1-negative chordoma is dismal. The standard treatment for localized chordoma, complete surgical resection with a wide margin, is seldom feasible for chordomas arising at the clivus in children, mainly due to associated complications. Therefore, other treatments for unresectable chordomas in children, including chemoradiotherapy, must be explored. Here, we report a 7-year-old girl with an INI1-negative chordoma of the clivus, who responded to conventional chemotherapy plus radiotherapy. Without surgical resection, she remains alive after 1 year and 7 months of the initial diagnosis. PMID- 30281527 TI - Ophthalmic manifestations associated with RARB mutations. PMID- 30281528 TI - Nonrheumatoid Fibrinous Pericarditis: A Medical Examiner Algorithm for the Diagnosis of Viral Myocarditis and Use of Molecular Diagnostic Techniques. AB - Classic "bread-and-butter" appearance of fibrinous pericarditis had been described in rheumatic disease and other immunologic diseases such as systemic lupus erythematosus, post-myocardial infarct, uremia, tuberculosis, radiation effects, bacterial, and viral etiology. In most of the described cases, pericarditis occurs as a delayed complication. We present a case of a 21-year-old white woman who was seen in the emergency department to rule out pulmonary embolism for shortness of breath, chest pain, and lightheadedness. The autopsy showed a collection of serous fluid into the pericardial sac with bread-and butter appearance. Microscopically, the pericardium showed acute inflammation with fibrinous exudates. Sections of the heart showed areas of lymphocytic infiltration with acute fibrinous inflammation of the pericardium. Vasculitis was seen in small blood vessels in the heart and was negative in other organs. No granuloma or necrotizing lesion was seen in microscopic sections of all organs including the heart, ruling out rheumatologic disease. The present study highlights the quest and design of an algorithm for a nonrheumatic disorder as the cause of pericarditis. Molecular studies were performed on heart tissue blocks for identification of cardiotropic viruses. Human parvovirus B19 was isolated from heart tissue blocks. The present case study highlights on updates in pathophysiology and diagnostic criteria for myocarditis along with the use of new molecular techniques for detection of idiopathic cardiomyopathies in a medical examiner setup.

PMID- 30281531 TI - Acquisition of analgesic properties by the cholecystokinin (CCK)/CCK2 receptor system within the amygdala in a persistent inflammatory pain condition. AB - Pain is associated with negative emotions such as anxiety, but the underlying neurocircuitry and modulators of the association of pain and anxiety remain unclear. The neuropeptide cholecystokinin (CCK) has both pronociceptive and anxiogenic properties, so we explored the role of CCK in anxiety and nociception in the central amygdala (CeA), a key area in control of emotions and descending pain pathways. Local infusion of CCK into the CeA of control rats increased anxiety, as measured in the light-dark box test, but had no effect on mechanical sensitivity. By contrast, intra-CeA CCK infusion 4 days after Complete Freund's Adjuvant (CFA) injection into the hindpaw resulted in analgesia, but also in loss of its anxiogenic capacity. Inflammatory conditions induced changes in the CeA CCK signaling system with an increase of CCK immunoreactivity and a decrease in CCK1, but not CCK2, receptor mRNA. In CFA rats, patch-clamp experiments revealed that CCK infusion increased CeA neuron excitability. It also partially blocked the discharge of wide dynamic range neurons in the dorsal spinal cord. These effects of CCK on CeA and spinal neurons in CFA rats were mimicked by the specific CCK2 receptor agonist, gastrin. This analgesic effect was likely mediated by identified CeA neurons projecting to the periaqueductal gray matter that express CCK receptors. Together, our data demonstrate that intra-CeA CCK infusion activated a descending CCK2 receptor-dependent pathway that inhibited spinal neuron discharge. Thus, persistent pain induces a functional switch to a newly identified analgesic capacity of CCK in the amygdala, indicating central emotion-related circuit controls pain transmission in spinal cord.

PMID- 30281533 TI - Efficacy of Neulasta or Neupogen on H-ARS and GI-ARS Mortality and Hematopoietic Recovery in Nonhuman Primates after 10 Gy Irradiation with 2.5% Bone-marrow Sparing. AB - A nonhuman primate model of acute, partial-body, high-dose irradiation with minimal (2.5%) bone-marrow sparing was used to assess endogenous gastrointestinal and hematopoietic recovery and the ability of Neulasta (pegylated granulocyte colony-stimulating factor) or Neupogen (granulocyte colony-stimulating factor) to enhance recovery from myelosuppression when administered at an increased interval between exposure and initiation of treatment. A secondary objective was to assess the effect of Neulasta or Neupogen on mortality and morbidity due to the hematopoietic acute radiation syndrome and concomitant gastrointestinal acute radiation syndrome. Nonhuman primates were exposed to 10.0 Gy, 6 MV, linear accelerator-derived photons delivered at 0.80 Gy min. All nonhuman primates received subject-based medical management. Nonhuman primates were dosed daily with control article (5% dextrose in water), initiated on day 1 postexposure; Neulasta (300 MUg kg), administered on days 1, 8, and 15 or days 3, 10, and 17 postexposure; or Neupogen (10 MUg kg), administered daily postexposure following its initiation on day 1 or day 3 until neutrophil recovery (absolute neutrophil count >=1,000 cells MUL for 3 consecutive days). Mortality in the irradiated cohorts suggested that administration of Neulasta or Neupogen on either schedule did not affect mortality due to gastrointestinal acute radiation syndrome or mitigate mortality due to hematopoietic acute radiation syndrome (plus gastrointestinal damage). Following 10.0 Gy partial-body irradiation with 2.5% bone-marrow sparing, the mean duration of neutropenia (absolute neutrophil count <500 cells MUL) was 22.4 d in the control cohort vs. 13.0 and 15.3 d in the Neulasta day 1, 8, 15 and day 3, 10, 17 cohorts, relative to 16.2 and 17.4 d in the Neupogen cohorts initiated on day 1 and day 3, respectively. The absolute neutrophil count nadirs were 48 cells MUL in the controls; 117 cells MUL and 40 cells MUL in the Neulasta days 1, 8, and 15 or days 3, 10, and 17 cohorts, respectively; and 75 cells MUL and 37 cells MUL in the Neupogen day 1 and day 3 cohorts, respectively. Therefore, the earlier administration of Neulasta or Neupogen was more effective in this model of marginal 2.5% bone-marrow sparing. The approximate 2.5% bone-marrow sparing may approach the threshold for efficacy of the lineage-specific medical countermeasure. The partial-body irradiation with 2.5% bone-marrow sparing model can be used to assess medical countermeasure efficacy in the context of the concomitant gastrointestinal and hematopoietic acute radiation syndrome sequelae. PMID- 30281534 TI - Blue laser imaging: a new image-enhanced endoscopy for the diagnosis of colorectal lesions. AB - BACKGROUND: Image-enhanced endoscopy enables real-time differential diagnosis of colorectal lesions through the observation of microvascular architecture. PURPOSE: To evaluate the efficacy of using blue laser imaging (BLI) for capillary pattern analysis in the differential diagnosis of neoplastic and non-neoplastic lesions. PATIENTS AND METHODS: This prospective study included 920 consecutive superficial lesions diagnosed in 457 patients. The capillary pattern was analysed using BLI-bright magnification on the basis of the Teixeira classification. Histopathology was used as the reference standard. RESULTS: The adenoma detection rate was 42.3%, with a mean of 0.95 adenomas per patient. Neoplastic lesions were predominant (70.3%), of which 33 (5.1%) had advanced histology. Neoplastic progression was significantly increased in patients aged at least 50 years, in lesions at least 10 mm and in lesions located in the right colon (P<0.01). BLI based capillary pattern analysis showed 95.5% accuracy, 95.7% sensitivity, 95.2% specificity, 97.9% positive predictive value and 90.3% negative predictive value in the diagnosis of neoplastic lesions. For 672 diminutive lesions (<=5 mm), BLI based capillary pattern analysis showed 95.7% accuracy, 96.6% sensitivity, 93.6% specificity, 97.2% positive predictive value and 92.2% negative predictive value. Analysing only lesions up to 5 mm in the rectum and sigmoid colon, the values were 95.2, 93.9, 96.5, 95.8 and 94.8%, respectively. CONCLUSION: BLI associated with magnification yielded excellent results for the real-time predictive histological diagnosis of colorectal lesions. PMID- 30281535 TI - Role of the von Willebrand factor and the VITRO score as predictors for variceal bleeding in patients with hepatitis C-related cirrhosis. AB - BACKGROUND: Noninvasive methods have been established to detect clinically significant portal hypertension in liver cirrhosis with variable limitations. The von Willebrand factor (vEF) has been found to increase in liver cirrhosis. AIM: The aim of this study was to explore the vEF and VITRO (von Willebrand factor antigen/platelet ratio) score in the prediction of variceal bleeding in patients with portal hypertension. MATERIALS AND METHODS: Fifty patients with hepatitis C related liver cirrhosis (25 patients with variceal bleeding and 25 without variceal bleeding) as well as 80 healthy controls were included. Laboratory investigations and upper gastrointestinal endoscopy were performed in all patients. Serum vEF was measured in the patient and the control group. The VITRO score was calculated. RESULTS: The mean levels of the vEF antigen and the VITRO score were higher in patients with variceal bleeding compared with patients without variceal bleeding and controls (P<0.001). At levels of at least 100.1 ng/ml and at least 0.732, the vEF and the VITRO score could predict variceal bleeding with a sensitivity and a specificity of 92 and 99.9% for the vEF and 80 and 68% for the VITRO score (area under the curve=0.982 and 0.843), respectively. Levels of vEF were correlated positively with esophageal varices grade. CONCLUSION: Serum vEF level and the VITRO score are potential noninvasive biomarkers for the prediction and risk stratification of variceal bleeding in hepatitis C-related liver cirrhosis. PMID- 30281536 TI - CaP Coating and Low-Level Laser Therapy to Stimulate Early Bone Formation and Improve Fixation of Rough Threaded Implants. AB - PURPOSE: This study aimed to compare in vivo osteogenesis on rough threaded dental implants with and without calcium phosphate (CaP) coating deposition, alone or in association with low-level laser therapy (LLLT) by gallium aluminum arsenide. MATERIAL AND METHODS: Four groups were studied: G1: implant; G2: implant + CaP coating; G3: implant + LLLT; and G4: implant + CaP coating + LLLT. LLLT was applied for 7 days at the surgical site before and after placing the implant. Topographic characterization was performed before surgery using scanning electron microscopy and energy dispersion spectrophotometry. Bone-implant contact (BIC) was measured after 1, 2, and 6 weeks and reverse torque after 6 weeks. In short periods, G2, G3, and G4 showed significantly greater BIC than G1 (P < 0.05), but no difference in BIC was observed at 6 weeks. However, the values for the removal torque test at 6 weeks were higher in G2 and G4 (P < 0.05). CONCLUSION: Both CaP coating alone and using LLLT induce cellular stimulation and improve BIC in short-term healing, resulting in higher implant fixation, and should be considered in clinical practice due to their low cost and high effectiveness. PMID- 30281537 TI - The effects of P2X7 receptor knockout on emotional conditions over the lifespan of mice. AB - Neuroinflammation is one of the key factors contributing to depression. Recent studies have identified P2X7 receptor (P2X7r) as a major inflammatory regulator. However, the effects of P2X7r knockout (KO) on emotional conditions over the lifespan of mice are unknown. In this study, the effects of P2X7r deletion on emotional conditions over the lifespan of mice were investigated in young-aged (2 month old), middle-aged (10 month old), and old-aged (18 month old) female P2X7r KO mice and age-matched female C57BL/6 mice. Behavioral tasks were conducted by open field test, forced swimming test and sucrose preference test. Mitochondrial structures and spine synapses in hippocampus were examined by electron microscopy. Enzyme-linked immunosorbent assay was used to analyze the expression of interleukin-1beta and tumor necrosis factor-alpha. Western blot analysis was used to assess the expression of nuclear factor-kappa B (NF-kappaB) pathway related proteins. The results indicated that middle-aged P2X7r KO mice displayed better emotional conditions than middle-aged WT mice. However, worse emotional conditions were observed in young-aged P2X7r KO mice. Moreover, abnormal mitochondrial structures and less spine synapses were observed in young-aged P2X7r KO mice. Mitochondrial structures were recovered and more spine synapses occurred in middle-aged P2X7r KO mice. In addition, expressions of interleukin 1beta, tumor necrosis factor-alpha, p-IKKalpha, p-IKKbeta, p-IkappaBalpha, and p NF-kappaBp65 were decreased in middle-aged P2X7r KO mice, but increased in young aged P2X7r KO mice. In conclusion, P2X7r KO improves the emotional conditions at later stages of the lifespan of mice, but not in all ages, suggesting time specific roles of immune response in nervous system through NF-kappaB signaling pathway.

AB - PURPOSE OF REVIEW: There is increasing evidence that extended-hours regimens are associated with improved outcomes for patients on maintenance hemodialysis programs. Home hemodialysis programs are a well established way for patients to benefit from extended-hours dialysis overnight; however, there are significant barriers to home hemodialysis, which means that for many this is not an option. In center, nocturnal hemodialysis is an increasingly recognized way of offering extended-hours treatment to patients unable to undertake home-based programs and is an underutilized modality for such patients to gain from the physiological benefits of extended-hours dialysis regimens. RECENT FINDINGS: Recent data suggest that nocturnal dialysis programs confer a significant survival advantage over both standard dialysis and short-daily dialysis regimens with evidence proposing that this is mediated through beneficial cardiovascular remodeling. Moreover, there is strong evidence that nocturnal dialysis regimens associate with significant improvements in quality-of-life measures and social well being. SUMMARY: Nocturnal hemodialysis is an underutilized way of offering extended hours hemodialysis to patients in both the home and in-center environments. As the evidence base around nocturnal dialysis grows, clinicians and dialysis providers are becoming increasingly obliged to investigate implementation strategies for nocturnal dialysis services to improve patient outcomes and experience of care.

We sought to examine the impact of BTT on long-term survival and quality of life after heart transplant. The population was all adult patients undergoing isolated heart transplantation in the United States between 2007 and 2017. Inclusion criteria covered BTT patients with a LVAD (only Heartmate II [HMII] or HeartWare Ventricular Assist System [HVAD]) and compared these with patients undergoing de novo heart transplantation. Our primary end-point was survival at 1, 2, and 5 years. Secondary end-points were functional status, return to work, and rates of hospital readmission and graft rejection. Unconditional and conditional survival was estimated with the Kaplan-Meier method. The independent influence of BTT on risk-adjusted mortality was determined using Cox proportional hazards models. In this period, 5,584 patients were bridged with an LVAD and 12,295 underwent de novo transplantation. Unconditional survival was 2% higher in de novo patients at 1, 2, and 5 years. After risk adjustment, BTT was associated with increased mortality at each time point. Unadjusted 5 year survival, conditional on 90 day survival, was similar between groups (82.6% vs. 83.4%; p = 0.15). Functional status, return to work, and unadjusted rates of hospital readmission and graft rejection were similar at 1, 2, 5 years. Bridge-to-transplant with LVADs provides excellent survival and similar quality of life to that of patients undergoing de novo heart transplantation. Bridge-to-transplant patients experience a slightly higher mortality rate within 90 days of transplantation. PMID- 30281541 TI - Clinical Outcomes of Impella Microaxial Devices Used to Salvage Cardiogenic Shock as a Bridge to Durable Circulatory Support or Cardiac Transplantation. AB - Temporary mechanical circulatory support (MCS) can be a bridge to decision for patients in severe cardiogenic shock who may be eligible for durable support or transplantation. Outcomes with Impella microaxial devices for salvage of severe shock in the end-stage heart failure population are not well described. Patients who underwent Impella placement as a bridge to decision, durable MCS, or transplantation were included. Eighty Impella devices (2.5 [1.3%], CP [53.8%], and 5.0 [45.0%]) were placed in 64 patients. Implant age was 56.2 +/- 12.5 years. Mean duration of assisted support was 13.2 +/- 15.1 days, and median duration per device was 7 days (interquartile range: 3-14). A total of 48.4% were in Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS 1) shock at implant, 51.6% in profile 2. Recent CPR (26.7%), ventilator use (67.2%), and extracorporeal membrane oxygenation (ECMO) use (26.7%) were frequent. Forty four of sixty four (68.8%) survived to next therapy: durable MCS (40.9%), OHT (36.4%), and recovery (22.7%). Overall 30 and 60 day survival were 67.2% and 65.6%, respectively. Thirty and 60 day survival conditional on having survived to next therapy were 94.1% and 91.2%, respectively. Survivors were less likely to be on ventilators (p = 0.049) or continuous renal replacement therapy (p < 0.001) but were otherwise not different from nonsurvivors by age, sex, INTERMACS profile, CPR, prevalence of ischemic cardiomyopathy, among other characteristics. Sixteen patients were directly bridged to heart transplantation, and all were alive at long-term follow-up. Impella devices can be used to salvage patients in severe heart failure as a bridge to decision, durable MCS, or transplantation. Baseline demographics are not predictive of survival. Their use for this indication is increasing and further investigations are warranted. PMID- 30281542 TI - A Proof of Concept Study, Demonstrating Extracorporeal Carbon Dioxide Removal Using Hemodialysis with a Low Bicarbonate Dialysate. AB - Extracorporeal carbon dioxide removal (ECCO2R) devices remove CO2 directly from blood, facilitating ultraprotective ventilation or even providing an alternative to mechanical ventilation. However, ECCO2R is not widely available, whereas dialysis is available in most intensive care units (ICUs). Prior attempts to provide ECCO2R with dialysis, by removing CO2 in the form of bicarbonate, have been plagued by metabolic acidosis. We hypothesized that bicarbonate dialysis is feasible, provided the plasma strong ion difference is maintained. We used a mathematical model to investigate the effects of bicarbonate removal on pH and CO2 in plasma, and performed in-vitro experiments to test CO2 removal using three dialysates with different bicarbonate concentrations (0, 16, and 32 mmol.L). Our modeling predicted a reduction in partial pressures of CO2 (PCO2) and increased pH with progressive lowering of plasma bicarbonate, provided strong ion difference and plasma proteins (Atot) were maintained. In our in-vitro experiments, total CO2 removal, scaled up to an adult size filter, was highest with our dialysate containing no bicarbonate, where we removed the equivalent of 94 ml.min (+/-3.0) of CO2. Under the same conditions, our dialysate containing a conventional bicarbonate concentration (32 mmol.L) only removed 5 ml.min (+/-4; p < 0.001). As predicted, pH increased following bicarbonate removal. Our data show that dialysis using low bicarbonate dialysates is feasible and result in a reduction in plasma PCO2. When scaled up, to estimate equivalent CO2 removal with an adult dialysis circuit, the amount removed competes with existing low-flow ECCO2R devices. PMID- 30281543 TI - An Innovative Ventricular Assist Device Strategy as a Bridge-to-Recovery in an Infant with Glenn Physiology. AB - Mechanical circulatory support for infants with single ventricle physiology remains challenging. Utilization of a ventricular assist device (VAD) has potential advantages over extracorporeal circulatory membrane oxygenation. As such, VAD utilization in single ventricle patients with refractory heart failure continues to be explored. Herein, we describe a novel VAD strategy to support an infant with Glenn physiology who presented in cardiogenic shock related to myocardial depression of unknown etiology. This VAD configuration supported the systemic circulation independent of the Glenn circulation. Seven days of VAD support resulted in recovery of myocardial and end-organ function leading to VAD removal. The patient remains alive and free from transplantation 16 months post VAD explantation. PMID- 30281544 TI - Development and Validation of a Life-Sized Mock Circulatory Loop of the Human Circulation for Fluid-Mechanical Studies. AB - Mock circulatory loops (MCLs) are usually developed for assessment of ventricular assist devices and consist of abstracted anatomical structures represented by connecting tubing pipes and controllable actuators which could mimic oscillating flow processes. However, with increasing use of short-term peripheral mechanical support (extracorporeal life support [ECLS]) and the upcoming evidence of even counteracting flow processes between the failing native circulation and ECLS, MCLs incorporating the peripheral vascular system and preserved anatomical structures are becoming more important for systematic assessment of these processes. For reproducible and standardized fluid-mechanical studies using magnetic resonance imaging, Doppler ultrasound, and computational fluid dynamics measurements, we developed a MCL of the human circulation. Silicon-based life sized dummies of the human aorta and vena cava (vascular module) were driven by paracorporeal pneumatic assist devices. The vascular module is placed in a housing with all arterial branches merging into peripheral resistance and compliances modules, and blood-mimicking fluid returns to the heart module through the venous dummy. Compliance and resistance chambers provide for an adequate simulation of the capillary system. Extracorporeal life support cannulation can be performed in the femoral and subclavian arteries and in the femoral and jugular veins. After adjusting vessel diameters using variable Hoffmann clamps, physiologic flow rates were achieved in the supraaortic branches, the renal and mesenteric arteries, and the limb arteries with physiologic blood pressure and cardiac output (4 L/min). This MCL provides a virtually physiologic platform beyond conventional abstracted MCLs for simulation of flow interactions between the human circulation and external circulation generated by ECLS.

AB - INTRODUCTION: Candidemia is the most frequent pediatric fungal infection, but incompletely elucidated in population-based settings. We performed a nationwide cohort study including all pediatric patients with candidemia in Denmark from 2004-2014 to determine age, incidence, species distribution, underlying diseases, patient management and outcomes. METHODS: All candidemia episodes were identified through the active nationwide fungemia surveillance program. Susceptibility testing followed the EUCAST E.Def 7 reference method. Chi-squared test, Fisher's exact test and Venn diagrams were used for statistical analyses. RESULTS: 153 pediatric patients (<=15 years) with 158 candidemia episodes were identified. The overall annual incidence rate was 1.3/100,000 population, higher for neonates (5.7/100,000 live births) and low birth weight (LBW) neonates (103.8/100.000 live births). From 2004-9 to 2010-2014, the proportion of C. albicans decreased from 74.4% to 64.7%, whereas fluconazole resistance increased from 7.8% to 17.7%. Virtually all patients had at least one underlying disease (98.6%) and multi morbidity was common (43.5%, >=2 underlying diseases). Underlying diseases differed by age with heart malformations and gastrointestinal disease prevalent in children younger than 3 years. The overall 30-days mortality was 10.2% and highest for neonates (17.1%). Mortality increased from 2004- to 2010-14, driven by an increase among older children. DISCUSSION: This first nationwide epidemiologic study of pediatric candidemia confirmed a high incidence among neonates and a substantial burden of comorbidities. Moreover, an increasing proportion of fluconazole resistant non-albicans species was observed. Our findings underline the importance of choosing correct treatment and continuous surveillance of pediatric candidemia. PMID- 30281547 TI - Antibiotic Resistance Among Pediatric-Sourced Ocular Pathogens: 8-year Findings from the ARMOR Surveillance Study. AB - BACKGROUND: The Antibiotic Resistance Monitoring in Ocular Microorganisms (ARMOR) study is a nationwide longitudinal antibiotic resistance surveillance program specific to bacterial pathogens commonly encountered in ocular infections. We evaluated resistance rates and trends among isolates obtained from pediatric patients (<=17 years of age). METHODS: Clinical centers across the US were invited to submit ocular isolates of Staphylococcus aureus, coagulase-negative staphylococci (CoNS), Streptococcus pneumoniae, Haemophilus influenzae, and Pseudomonas aeruginosa to a central laboratory. Minimum inhibitory concentrations (MICs) for various antibiotic classes were determined by broth microdilution per Clinical and Laboratory Standards Institute guidelines and interpreted as susceptible, intermediate, or resistant based on available breakpoints. Longitudinal trends were analyzed using a Cochran-Armitage test for linear trends in a proportion. RESULTS: Of 4829 isolates collected from January 2009-December 2016, 995 isolates, sourced primarily from hospitals and referral centers, were obtained from pediatric patients (n=286 H. influenzae, n=284 S. aureus, n=213 CoNS, n=150 S. pneumoniae, and n=62 P. aeruginosa). With few exceptions, P. aeruginosa and H. influenzae were generally susceptible to the antibiotics tested. Of S. aureus and CoNS isolates, respectively, 56% and 72% were resistant to azithromycin and 24% and 47% were methicillin-resistant (MR); concurrent resistance to other drug classes and multidrug resistance (>=3 drug classes) were prevalent among MR staphylococci. Of S. pneumoniae isolates, 38% and 35% demonstrated resistance to azithromycin and penicillin, respectively. Besifloxacin had the lowest MIC against the Gram-positive isolates. CONCLUSIONS: These in vitro data suggest antibiotic resistance is common among staphylococcal and pneumococcal isolates collected from pediatric patients with ocular infections. Methicillin resistance was prevalent among staphylococci with many strains demonstrating multidrug resistance. These findings may not be representative of resistance trends in community-based practices. PMID- 30281548 TI - Community Origins and Regional Differences Highlight Risk of Plasmid-Mediated Fluoroquinolone Resistant Enterobacteriaceae Infections in Children. AB - BACKGROUND: Fluoroquinolones (FQs) are uncommonly prescribed in children, yet pediatric multidrug-resistant (MDR)-Enterobacteriaceae (Ent) infections often reveal FQ resistance (FQR). We sought to define the molecular epidemiology of FQR and MDR-Ent in children. METHODS: A case-control analysis of children with MDR Ent infections at 3 Chicago hospitals was performed. Cases were children with third-generation-cephalosporin-resistant (3GCR) and/or carbapenem-resistant (CR) Ent infections. PCR and DNA analysis assessed bla and plasmid-mediated FQR (PMFQR) genes. Controls were children with 3GC and carbapenem susceptible-Ent infections matched by age, source and hospital. We assessed clinical epidemiologic predictors of PMFQR Ent infection. RESULTS: Of 169 3GCR and/or CR Ent isolates from children (median age 4.8 years), 85 were FQR; 56 (66%) contained PMFQR genes. The predominant organism was E. coli and most common bla gene blaCTX-M-1 group. In FQR isolates, PMFQR gene mutations included aac6'1b-cr, oqxA/B, qepA, and qnrA/B/D/S in 83%, 15%, 13% and 11% of isolates, respectively. FQR E. coli was often associated with phylogroup B2, ST43/ST131. On multivariable analysis, PMFQR Ent infections occurred mostly in outpatients (OR 33.1) of non black-white-Hispanic race (OR 6.5). Residents of Southwest Chicago were >5 times more likely to have PMFQR-Ent infections than those in the reference region, while residence in Central Chicago was associated with a 97% decreased risk. Other demographic, comorbidity, invasive-device, antibiotic use, or healthcare differences were not found. CONCLUSIONS: The strong association of infection with MDROs showing FQR with patient residence rather than with traditional risk factors suggests that the community environment is a major contributor to spread of these pathogens in children. PMID- 30281550 TI - Factors Associated With First Medication Time for Children Treated in the Emergency Department for Asthma. AB - OBJECTIVES: Acute asthma exacerbations are among the most common reasons for childhood emergency department (ED) visits and hospitalizations. Although early ED administration of asthma medication has been shown to decrease hospitalizations, studies of factors associated with early ED asthma medication delivery have been limited. The objective of our study was to identify patient- and ED-related factors associated with early medication delivery among children treated in the ED for asthma exacerbations. METHODS: This retrospective study used electronic health record data from all encounters for a primary diagnosis of asthma in an academic children's hospital ED during the study period 2009 to 2013. Using multivariate logistic regression, we identified the association between patient- and ED-related factors and the time to first medication defined as a binary outcome using a threshold of 1 hour from ED arrival. We then stratified our analysis by triage level (Emergency Severity Index [ESI]). RESULTS: Of the 4846 encounters during the study period, 62% were male, mean age was 7.30 years, 76% had public insurance, and 57% had an ESI level of 3. Medication was administered within 1 hour of arrival in 2236 encounters (46%). After adjusting for covariates, multivariate logistic regression revealed that patients were less likely to have medications within 1 hour when they had less severe ESI (ESI 2 vs ESI 4: odds ratio [OR], 0.139; confidence interval [CI], 0.114-0.170), arrived via non-emergency medical services (OR, 0.525; CI, 0.413 0.665), or arrived to a crowded ED (OR, 0.574; CI, 0.505-0.652). Age, sex, and insurance type were not associated with timeliness of initial medication administration. Stratified analyses demonstrated that the crowding effect was larger for less severely ill patients. CONCLUSIONS: Our study found that patient severity (acuity level, arrival mode) and level of ED crowing-but not demographic factors-are associated with the administration of medication in the first hour to pediatric patients with asthma. Our findings may be helpful in redesigning asthma care management strategies. PMID- 30281549 TI - Disease- and Treatment-Related Morbidity in Adolescents With Perinatal HIV Infection in Asia. AB - BACKGROUND: Perinatally HIV-infected adolescents (PHIVA) are exposed to a chronic systemic infection and long-term antiretroviral therapy (ART), leaving them susceptible to morbidities associated with inflammation, immunodeficiency, and drug toxicity. METHODS: Data collected 2001-2016 from PHIVA aged 10-19 years within a regional Asian cohort were analysed using competing risk time-to-event and Poisson regression analyses to describe the nature and incidence of morbidity events and hospitalisations, and identify factors associated with disease related, treatment-related, and overall morbidity. Morbidity was defined according to WHO clinical staging criteria and US National Institutes of Health Division of AIDS criteria. RESULTS: A total 3,448 PHIVA contributed 17,778 person years. Median age at HIV diagnosis was 5.5 years and ART initiation was 6.9 years. There were 2,562 morbidity events and 307 hospitalisations. Cumulative incidence for any morbidity was 51.7% and hospitalisation was 10.0%. Early adolescence was dominated by disease-related infectious morbidity, with a trend toward non-infectious and treatment-related morbidity in later adolescence. Higher overall morbidity rates were associated with a CD4 count <350 cells/uL, HIV viral load >=10,000 copies/mL, and experiencing prior morbidity at age <10 years. Lower overall morbidity rates were found for those aged 15-19 years compared to 10-14 years, and those who initiated ART at age 5-9 years compared to <5 or >=10 years. CONCLUSIONS: Half of our PHIVA cohort experienced a morbidity event, with a trend from disease-related infectious events to treatment-related and non-infectious events as PHIVA age. Antiretroviral therapy initiation to prevent immune system damage, optimise virologic control, and minimise childhood morbidity are key to limiting adolescent morbidity. PMID- 30281551 TI - A Time-and-Motion Study of Clinical Trial Eligibility Screening in a Pediatric Emergency Department. AB - OBJECTIVE: Challenges with efficient patient recruitment including sociotechnical barriers for clinical trials are major barriers to the timely and efficacious conduct of translational studies. We conducted a time-and-motion study to investigate the workflow of clinical trial enrollment in a pediatric emergency department. METHODS: We observed clinical research coordinators during 3 clinically staffed shifts. One clinical research coordinator was shadowed at a time. Tasks were marked in 30-second intervals and annotated to include patient screening, patient contact, performing procedures, and physician contact. Statistical analysis was conducted on the patient enrollment activities. RESULTS: We conducted fifteen 120-minute observations from December 12, 2013, to January 3, 2014 and shadowed 8 clinical research coordinators. Patient screening took 31.62% of their time, patient contact took 18.67%, performing procedures took 17.6%, physician contact was 1%, and other activities took 31.0%. CONCLUSIONS: Screening patients for eligibility constituted the most time. Automated screening methods could help reduce this time. The findings suggest improvement areas in recruitment planning to increase the efficiency of clinical trial enrollment. PMID- 30281552 TI - Management of Wheezy Preschoolers in the Emergency Department: A Discrete Choice Experiment. AB - OBJECTIVES: This study aimed to elicit pediatric emergency physician's treatment choices for preschool-aged children with wheeze, determine the characteristics of the presenting child that influence treatment choices, and determine whether there is clinical equipoise by eliciting physician willingness to enroll these children in a placebo-controlled trial of corticosteroids. METHODS: Discrete choice experiments varying the characteristics of the presenting child were designed to elicit Canadian emergency physician's treatment choices, both in the emergency department (ED) and at discharge, for young children presenting with wheeze and their willingness to enroll in a randomized controlled trial (RCT). RESULTS: Most physicians chose to treat children with albuterol both in the ED and at discharge for all clinical scenarios. The proportion of physicians who chose to treat children with oral corticosteroids both in the ED and at discharge varied widely (from 12% to 81%) across all scenarios. Physician preference whether preschool children with wheeze should be treated with corticosteroids varied depending on the child's age, history of atopy, and previous and continuous wheeze. Between 73% and 86% of physicians were willing to enroll these children in an RCT indicating clinical equipoise. CONCLUSIONS: Physician treatment choices varied widely indicating clinical equipoise as to the effectiveness of corticosteroids in this population of patients. Management choices with respect to albuterol and corticosteroids were not consistent with published national and international guidelines. In line with this finding, physician's considerable willingness to enroll these children in an RCT may suggest that they are seeking guidance on how to manage these patients. PMID- 30281553 TI - Missed Diagnosis of Anaphylaxis in Patients With Pediatric Urticaria in Emergency Department. AB - OBJECTIVES: This study was to determine the characteristics of missed diagnosis of pediatric anaphylaxis that were registered as urticaria only at the emergency department (ED) by comparing those who had only urticaria symptoms with those who had both anaphylaxis and urticaria symptoms. METHODS: Subjects were classified into missed anaphylaxis and urticaria group according to whether satisfied anaphylaxis diagnostic criteria or not. Anaphylaxis group, those who were initially registered as anaphylaxis with urticaria and anaphylaxis symptoms simultaneously, were further investigated. RESULTS: The missed anaphylaxis group included 37 patients of 1051 pediatric urticaria patients. The anaphylaxis group included 11 patients. The time from symptom onset to ED arrival in the missed anaphylaxis group was shorter than the urticaria group. More patients in the missed anaphylaxis group had a history of past food allergy. Seafood, egg, and milk were more common causes of allergy in the missed anaphylaxis group; however, idiopathic causes were more common in the urticaria group. Symptom was more severe in the missed anaphylaxis group than the urticaria group. More treatments except antihistamine were performed at ED in the missed anaphylaxis group. Cardiovascular symptoms were more common in the anaphylaxis group than the missed anaphylaxis group. CONCLUSIONS: Of all pediatric urticaria patients, 3.5% of patients were not registered as anaphylaxis although they had anaphylaxis symptoms. Missed diagnosis of anaphylaxis in pediatric urticaria patients at ED was associated with a history of past food allergy, milk, egg, and seafood as causes of allergy, treated with fluid administration, steroid, and epinephrine. PMID- 30281554 TI - Prehospital Analgesic Administration by Parents for Pain Relief in Children. AB - PURPOSE: Undertreatment of pain by caregivers before presentation to the pediatric emergency department (ED) has been well documented. What has yet to be elucidated are the reasons why caregivers fail to adequately treat pain before arrival in the ED and whether there are differences based on ethnic background or age of the child. The objectives of this study were to determine the barriers to giving pain medication for injuries before ED arrival and to determine if there are any ethnic- or age-related variations to giving pain relief at home. METHODS: This prospective descriptive study was conducted in the ED at a tertiary care, freestanding children's hospital with a current annual census of approximately 80,000. An anonymous prospective questionnaire was given to caregivers of children between 2 and 17 years of age presenting to the ED between August 2013 and September, 2014. The study population was obtained as a convenience sample. All were self-referred with chief complaints of head, ear, or extremity pain. The questionnaire asked about pain medications and doses given at home as well as the reasons parents gave medication or refused to give pain medication before arrival. Charts were then abstracted to obtain demographic information and care received in the ED. RESULTS: A total of 154 (45.6%) of the 338 patients enrolled did not receive pain relief before coming to the ED. There were no differences in pain medication received at home based on ethnicity (P = 0.423) or age (P = 0.580). Parents could choose from a list of multiple reasons as to why pain medications were given and/or free text their own answer. The main reasons given by parents were that the accident did not happen at home (28.6%) and that they did not have time to give pain relief before coming to the ED (13%). Other common answers were "had no pain relievers at home" (12.4%) or "afraid it would be wrong/harmful/did not want to mask symptoms" (9.2%). Seventeen parents responded that their child did not complain of pain. Overall, only 28.1% of participants stated lack of pain medications at home. CONCLUSIONS: In this study, approximately half of all children receive an analgesic for their painful condition before coming to the ED. Continued education regarding pain relief before coming to the ED is needed. Future studies will focus on educating parents to provide analgesia at home. PMID- 30281555 TI - Detectability of Brain Metastases by Using Frequency-Selective Nonlinear Blending in Contrast-Enhanced Computed Tomography. AB - PURPOSE: The aim of this study to evaluate the role of frequency-selective nonlinear blending (FS-NLB) for the detectability of brain metastases with contrast-enhanced computed tomography (CECT) using magnetic resonance imaging (MRI) as standard of reference. MATERIALS AND METHODS: A retrospective patient data search at our institution yielded 91 patients who underwent both brain CECT and MRI for screening of brain metastases (n = 173) between 2014 and 2016 (mean time interval, 29 +/- 37 [malignant: 15 +/- 16/benign: 42 +/- 47] days). A recently introduced FS-NLB postprocessing technique was applied to CECT images. Two readers interpreted all CT images in an independent fashion. The conventional, linear blending (LB) CT images were evaluated first. After a washout period, the same readers evaluated the FS-NLB CT images. The standard of reference was established by a consensus interpretation of the brain MRI studies. Outcome variables included determination of best performing FS-NLB settings, region of interest (ROI)-based calculation of contrast-to-noise ratios (CNRs), size, and number of brain metastases. Based on the number of metastases, we classified patients in 5 therapeutically relevant categories (0, no metastasis; 1, singular metastasis; 2, less than 4 metastases; 3, >4 and <10 metastases; 4, >10 metastases). Statistical comparison and diagnostic performance tests were applied. RESULTS: A center of 47 Hounsfield units (HU), delta of 5 HU, and slope of 5 resulted in the best delineation of hyperdense brain metastases, whereas for hypodense brain metastases, a center of 32 HU, delta of 5 HU, and slope of 5 showed best delineation. Frequency-selective nonlinear blending significantly increased CNR in hyperdense cerebral metastases (CECT: 9.11 [6.9-10.9], FS-NLB: 18.1 [11.9-22.8]; P < 0.0001) and hypodense cerebral metastases (CECT: 6.3 [5.2 8], FS-NLB: 17.8 [14.5-19.7]; P < 0.0001). Sensitivity, specificity, negative predictive values, positive predictive values, and accuracy for LB, and FS-NLB were 40%, 98%, 99%, 31%, and 52%, and 62%, 94%, 97%, 40%, and 69%, respectively. Magnetic resonance imaging, LB, and FS-NLB classification of metastatic patients were group 0 (47, 47, 46), group 1 (14, 8, 11), group 2 (16, 12, 15), group 3 (8, 7, 8), and group 4 (6, 4, 6). CONCLUSIONS: Frequency-selective nonlinear blending postprocessing of CECT significantly increases the detection of brain metastases over conventional CECT; however, the sensitivity remains lower than MRI. Frequency-selective nonlinear blending is slightly inferior in the categorization of patients into therapeutically relevant groups, when compared with MRI. PMID- 30281556 TI - Clinical Feasibility of Gadoxetic Acid-Enhanced Isotropic High-Resolution 3 Dimensional Magnetic Resonance Cholangiography Using an Iterative Denoising Algorithm for Evaluation of the Biliary Anatomy of Living Liver Donors. AB - OBJECTIVES: The aim of this study was to evaluate the clinical feasibility of gadoxetic acid-enhanced isotropic high-resolution (IHR) 3-dimensional (3D) T1 weighted (T1W) magnetic resonance cholangiography (MRC) using an iterative denoising (ID) algorithm for evaluation of the biliary anatomy of living liver donors in comparison with conventional 3D multislice T2-weighted (T2W) MRC. MATERIALS AND METHODS: In this institutional review board-approved retrospective study, a total of 75 living liver donors who underwent conventional 3D multislice T2W-MRC and IHR-3D-T1W-MRC on a 3 T scanner and subsequent right hepatectomy for liver donation were included. Isotropic high-resolution T1W-MRCs were obtained in both axial and coronal planes using the 3D VIBE Dixon sequence and an ID algorithm implemented with wavelet thresholding of 3D complex-valued data of the noise level, g-factor, and k-space filtering. Thereafter, 3 board-certified radiologists independently reviewed the examinations for visibility and sharpness of the bile ducts (BDs), as well as overall image quality on a 5-point scale. For diagnostic performance, anatomic variations of the BD, length of right hepatic duct, and the expected number of BD openings at right hepatectomy were also recorded. As the reference standard, BD variation was determined by surgeons in consensus using intraoperative real-time fluorescent cholangiography. RESULTS: Mean acquisition times of 3D-T2W-MRC and IHR-T1W-MRC were 367 seconds and 17 seconds (P < 0.001), respectively. Compared with 3D-T2W-MRCs, IHR-T1W-MRCs yielded significantly improved visibility and sharpness of all evaluated intrahepatic bile ducts (all Ps < 0.05), and higher overall image quality (P < 0.01). The IHR-T1W-MRCs also demonstrated significantly higher agreement in BD variation (87.6% vs 81.3%, P = 0.03) and expected BD openings (76.9% vs 70.2%, P = 0.006) than 3D-T2W-MRC compared with the reference standard. Interobserver agreement in estimating the length of right hepatic duct, IHR-T1W-MRC showed excellent interobserver agreement (intraclass correlation coefficient, 0.94), whereas 3D-T2W-MRC showed good interobserver agreement (intraclass correlation coefficient, 0.78). CONCLUSIONS: Isotropic high-resolution T1W-MRCs with ID provided significantly improved BD image quality and more accurate depiction of the BD anatomy and BD openings at right donor hemihepatetomy than 3D-T2W-MRC. PMID- 30281557 TI - Synthetic 2-Dimensional Mammography Can Replace Digital Mammography as an Adjunct to Wide-Angle Digital Breast Tomosynthesis. AB - OBJECTIVES: The aim of this study was to evaluate the detection rate and diagnostic performance of 2-dimensional synthetic mammography (SM) as an adjunct to wide-angle digital breast tomosynthesis (WA-DBT) compared with digital mammography (DM) alone or to DM in combination with WA-DBT. MATERIALS AND METHODS: There were 205 women with 179 lesions included in this retrospective reader study. Patients underwent bilateral, 2-view (2v) DM and WA-DBT between March and June 2015. The standard of reference was histology and/or 1-year stability at follow-up. Four blinded readers randomly evaluated images according to the BI-RADS lexicon from 3 different protocols: 2v DM alone, 2v DM with 2v WA DBT, and 2v SM with 2v WA-DBT. Detection rate, sensitivity, specificity, and accuracy were calculated and compared using multivariate analysis. Readers' confidence and image quality were evaluated. RESULTS: The detection rate ranged from 68.7% to 79.9% for DM, 76.5% to 84.4% for DM with WA-DBT, and 73.2% to 84.9% for SM with WA-DBT. Sensitivity and accuracy were significantly higher when DBT was available (P < 0.001). Specificity did not differ significantly between DM only, DM with WA-DBT, or SM with WA-DBT (P >= 0.846). Wide-angle DBT combined readings did not differ between SM and DM in terms of sensitivity, specificity, and accuracy (P >= 0.341). Readers' confidence and image quality was rated good to excellent. CONCLUSIONS: Wide-angle DBT combined with DM or SM increases sensitivity and accuracy without reducing specificity compared with DM alone. Wide-angle DBT combined readings did not differ between SM and DM; therefore, SM should replace DM for combined readings with WA-DBT.

DESIGN: A unique case of living donor liver transplantation from an HIV-positive mother to her HIV-negative child in South Africa. Two aspects of this case are ground-breaking. First, it involves living donation by someone who is HIV-positive and second it involves controlled transplant of an organ from an HIV-positive donor into an HIV-negative recipient, with the potential to prevent infection in the recipient. METHODS: Standard surgical procedure for living donor liver transplantation at our centre was followed. HIV-prophylaxis was administered preoperatively. Extensive, ultrasensitive HIV testing, over and above standard diagnostic assays, was undertaken to investigate recipient serostatus and is ongoing. RESULTS: Both mother and child are well, over 1 year posttransplantation. HIV seroconversion in our recipient was detected with serological testing at day 43 posttransplant. However, a decline in HIV antibody titres approaching undetectable levels is now being observed. No plasma, or cell-associated HIV-1 DNA has been detected in the recipient at any time-point since transplant. CONCLUSION: This case potentially opens up a new living liver donor pool which might have clinical relevance in countries where there is a high burden of HIV and a limited number of deceased donor organs or limited access to transplantation. However, our recipient's HIV status is equivocal at present and additional investigation regarding seroconversion events in this unique profile is ongoing.

AB - OBJECTIVE: In order to standardize use of our hospital's computerized asthma order set, which was developed based on an asthma clinical practice guideline, for moderately ill children presenting for care of asthma, we developed a quality improvement bundle, including a time-limited pay-for-performance component, for pediatric emergency department and pediatric urgent care faculty members. METHODS: Following baseline measurement, we used a run-in period for education, feedback, and improvement of the asthma order set. Then, faculty members earned 0.1% of salary during each of 10 successive months (evaluation period) in which the asthma order set was used in managing 90% or more of eligible patients. RESULTS: At baseline, the asthma order set was used in managing 60.5% of eligible patients. Order set use rose sharply during the run-in period. During the 10 month evaluation period, use of the asthma order set was significantly above baseline, with a mean of 91.6%; faculty earned pay-for-performance bonuses during 8 of 10 possible months. Following completion of the evaluation period, asthma order set use remained high. CONCLUSIONS: A quality improvement bundle, including a time-limited pay-for-performance component, was associated with a sustained increase in the use of a computerized asthma order set for managing moderately ill asthmatic children. PMID- 30281578 TI - Infectious Endocarditis Prophylaxis in Children. AB - Infectious endocarditis (IE) is a rare illness with high morbidity and mortality. Incidence of IE is on the rise in industrialized countries, particularly as those with congenital heart defects are living longer and the use of indwelling central catheters increases. With the 2007 American Heart Association guidelines, there has been a shift in recommending antibiotic prophylaxis only to high-risk patient populations. This clinical review will highlight the changing epidemiology and etiology of IE, followed by an emphasis on the appropriate indications for antibiotic prophylaxis in high-risk populations undergoing specific procedures.

AB - Ultrasonography can be useful in the evaluation of children with abdominal complaints and may be the initial imaging modality in patients presenting with a newly recognized abdominal mass. Hepatoblastoma is an uncommon cause of acute abdominal pain in children and can rarely metastasize to the heart through vascular invasion. We report a case in which a 4-year-old girl who presented to the emergency department with abdominal pain promptly underwent point-of-care ultrasound and was subsequently diagnosed with intracardiac invasion of an abdominal tumor. PMID- 30281581 TI - Development and Pilot Testing of a Computerized Asthma Kiosk to Initiate Chronic Asthma Care in a Pediatric Emergency Department. AB - OBJECTIVES: Emergency department (ED) visits are an opportunity to initiate chronic asthma care. Ideally, this care should be implemented in a fashion that limits utilization of scarce ED resources. We developed, iteratively refined, and pilot tested the feasibility of a computerized asthma kiosk to (1) capture asthma information, (2) deliver asthma education, and (3) facilitate guideline-based chronic asthma management. METHODS: The following are the 4 phases of this study: (1) developing the content and structure of a computerized asthma kiosk, (2) iterative refinement through heuristic testing by human-computer interface experts, (3) usability testing with ED providers (n = 4) and caregivers of children with asthma (n = 4), and (4) pilot testing the kiosk with caregivers (n = 31) and providers in the ED (n = 18). Outcome measures for the pilot-testing phase were the proportion of ED providers who prescribed long-term controller medication (LTCM) and asthma action plans (AsAPs) and the proportion of children who took LTCMs and attended primary care providers follow-up. RESULTS: After kiosk development and refinement, pilot implementation resulted in LTCMs prescribing and AsAP provision for 19 (61%) of 31 and 17 (55%) of 31 patients, respectively. Before kiosk use, the proportion of the 18 ED providers who reported prescribing LTCM was 1 (5%) of 18, and providing AsAPs was 0 (0%) of 18. Eighteen (58%) of the 31 caregivers reported that their children used LTCMs after kiosk use and 13 (42%) of 31 reported following up with the primary care provider within 1 month of the ED visits. CONCLUSIONS: A rigorously developed asthma kiosk showed promise for initiating chronic asthma care in the ED.

AB - BACKGROUND Colon cancer is one of the most common cancers and it is the fourth leading cause of cancer-related deaths worldwide. YAP can promote cell proliferation and inhibit apoptosis, leading to loss of cell contact inhibition and promoting malignant cell transformation. MATERIAL AND METHODS In this study we analyzed the effects of different curcumin concentrations on the proliferation of colon cancer cells using MTT and colony formation assays. Western blot detection was performed to confirm the YAP, LC3-II, and P62 expression. RESULTS Curcumin inhibited proliferation and promoted colon cancer cell autophagy. In addition, Western blot results indicated that curcumin suppressed YAP expression in colon cancer cells. To assess the mechanism, we treated the cell lines with curcumin and assessed YAP overexpression and YAP knockdown. The results revealed that curcumin inhibits the proliferation and promotes autophagy of these cell lines. Western blot results showed that curcumin reversed the effect of YAP in colon cancer cells. CONCLUSIONS Our results suggest that YAP has great promise for treatment of colon cancer and that it might be a potential diagnostic marker for colon cancer. PMID- 30281586 TI - Smooth super-twisting sliding mode control for the class of underactuated systems. AB - In this article, Smooth Super-twisting Sliding Mode Control (SSTWSMC) is investigated for the class of underactuated system. In underactuated systems, the control design is not directly applicable as for other systems (known as fully actuated systems). Therefore, at initial step, a nonlinear uncertain model of systems is transformed into the controllable canonical form, and then Smooth Super Twisting (SSTW) based Sliding Mode Control (SMC) is devised for the control design purpose for the considered class. In addition, closed loop stability of the proposed technique is presented in a fascinating way. The effectiveness and supremacy of the proposed control technique is proven by extensive analysis between conventional Sliding Mode Control (SMC), Super twisting (STW) sliding mode control and Smooth Super-twisting Sliding Mode Control (SSTWSMC). The comprehensive analysis evaluates the attributes like robustness enhancement, settling time, control effort, chattering reduction, overshoot, sliding mode convergence, etc. and is supported by simulations as well as practical implementation on ball and beam balancer (which is considered as application example). PMID- 30281588 TI - Violence detection in surveillance video using low-level features. AB - It is very important to automatically detect violent behaviors in video surveillance scenarios, for instance, railway stations, gymnasiums and psychiatric centers. However, the previous detection methods usually extract descriptors around the spatiotemporal interesting points or extract statistic features in the motion regions, leading to limited abilities to effectively detect video-based violence activities. To address this issue, we propose a novel method to detect violence sequences. Firstly, the motion regions are segmented according to the distribution of optical flow fields. Secondly, in the motion regions, we propose to extract two kinds of low-level features to represent the appearance and dynamics for violent behaviors. The proposed low-level features are the Local Histogram of Oriented Gradient (LHOG) descriptor extracted from RGB images and the Local Histogram of Optical Flow (LHOF) descriptor extracted from optical flow images. Thirdly, the extracted features are coded using Bag of Words (BoW) model to eliminate redundant information and a specific-length vector is obtained for each video clip. At last, the video-level vectors are classified by Support Vector Machine (SVM). Experimental results on three challenging benchmark datasets demonstrate that the proposed detection approach is superior to the previous methods. PMID- 30281587 TI - Cross-resistance is modular in bacteria-phage interactions. AB - Phages shape the structure of natural bacterial communities and can be effective therapeutic agents. Bacterial resistance to phage infection, however, limits the usefulness of phage therapies and could destabilise community structures, especially if individual resistance mutations provide cross-resistance against multiple phages. We currently understand very little about the evolution of cross resistance in bacteria-phage interactions. Here we show that the network structure of cross-resistance among spontaneous resistance mutants of Pseudomonas aeruginosa evolved against each of 27 phages is highly modular. The cross resistance network contained both symmetric (reciprocal) and asymmetric (nonreciprocal) cross-resistance, forming two cross-resistance modules defined by high within- but low between-module cross-resistance. Mutations conferring cross resistance within modules targeted either lipopolysaccharide or type IV pilus biosynthesis, suggesting that the modularity of cross-resistance was structured by distinct phage receptors. In contrast, between-module cross-resistance was provided by mutations affecting the alternative sigma factor, RpoN, which controls many lifestyle-associated functions, including motility, biofilm formation, and quorum sensing. Broader cross-resistance range was not associated with higher fitness costs or weaker resistance against the focal phage used to select resistance. However, mutations in rpoN, providing between-module cross resistance, were associated with higher fitness costs than mutations associated with within-module cross-resistance, i.e., in genes encoding either lipopolysaccharide or type IV pilus biosynthesis. The observed structure of cross resistance predicted both the frequency of resistance mutations and the ability of phage combinations to suppress bacterial growth. These findings suggest that the evolution of cross-resistance is common, is likely to play an important role in the dynamic structure of bacteria-phage communities, and could inform the design principles for phage therapy treatments. PMID- 30281589 TI - Tooth crown tissue proportions and enamel thickness in Early Pleistocene Homo antecessor molars (Atapuerca, Spain). AB - Tooth crown tissue proportions and enamel thickness distribution are considered reliable characters for inferring taxonomic identity, phylogenetic relationships, dietary and behavioural adaptations in fossil and extant hominids. While most Pleistocene hominins display variations from thick to hyper-thick enamel, Neanderthals exhibit relatively thinner. However, the chronological and geographical origin for the appearance of this typical Neanderthal condition is still unknown. The European late Early Pleistocene species Homo antecessor (Gran Dolina-TD6 site, Sierra de Atapuerca) represents an opportunity to investigate the appearance of the thin condition in the fossil record. In this study, we aim to test the hypothesis if H. antecessor molars approximates the Neanderthal condition for tissue proportions and enamel thickness. To do so, for the first time we characterised the molar inner structural organization in this Early Pleistocene hominin taxon (n = 17) and compared it to extinct and extant populations of the genus Homo from African, Asian and European origin (n = 355). The comparative sample includes maxillary and mandibular molars belonging to H. erectus, East and North African Homo, European Middle Pleistocene Homo, Neanderthals, and fossil and extant H. sapiens. We used high-resolution images to investigate the endostructural configuration of TD6 molars (tissue proportions, enamel thickness and distribution). TD6 permanent molars tend to exhibit on average thick absolute and relative enamel in 2D and 3D estimates, both in the complete crown and the lateral enamel. This condition is shared with the majority of extinct and extant hominin sample, except for Neanderthals and some isolated specimens. However, while the total crown percentage of dentine in TD6 globally resembles the low modern values, the lateral crown percentage of dentine tends to be much higher, closer to the Neanderthal signal. Similarly, the H. antecessor molar enamel distribution maps reveal a relative distribution pattern that is more similar to the Neanderthal condition (with the thickest enamel more spread at the periphery of the occlusal basin) rather than that of other fossil specimens and modern humans (with thicker cuspal enamel). Future studies on European Middle Pleistocene populations will provide more insights into the evolutionary trajectory of the typical Neanderthal dental structural organization. PMID- 30281590 TI - Leisure time activities as mediating variables in functional disability progression: An application of parallel latent growth curve modeling. AB - OBJECTIVES: The aims of this study were to investigate (1) whether and (2) the extent to which Taiwanese older adults' leisure time activity (LTA) trajectories mediated the potential association between their sociodemographic factors and their functional disability trajectories. METHODS: Longitudinal data from four waves of the Taiwan Longitudinal Study on Aging (TLSA), collected between 1996 and 2007, were used for analysis (N = 3,429). Parallel-process latent growth curve modeling was adopted to evaluate the process by which LTA mediated between sociodemographic factors (age, gender, education, self-rated health, comorbidities, and depression) and the outcome process of functional disabilities. RESULTS: When mediated by baseline level of LTA, five sociodemographic factors-age, gender, education level, self-rated health, and number of comorbidities-had significant and negative mediating effects on baseline or change in functional disability, thus improving disability outcomes. However, four of the sociodemographic factors (age, education level, and number of comorbidities), when mediated through the rate of change in LTA, were found to have significant and positive mediating effects, which increased disability levels. The proportion of effects mediated by the LTA trajectory ranged from 0% to 194%. DISCUSSION: The large proportion of effects mediated through the LTA process underlines the importance of LTA to public health policy and health programs for older adults. The study's findings shed light on how to better target populations of older adults to promote an active lifestyle and achieve more successful aging in late life in Asian countries. PMID- 30281592 TI - Wrangling distributed computing for high-throughput environmental science: An introduction to HTCondor. AB - Biologists and environmental scientists now routinely solve computational problems that were unimaginable a generation ago. Examples include processing geospatial data, analyzing -omics data, and running large-scale simulations. Conventional desktop computing cannot handle these tasks when they are large, and high-performance computing is not always available nor the most appropriate solution for all computationally intense problems. High-throughput computing (HTC) is one method for handling computationally intense research. In contrast to high-performance computing, which uses a single "supercomputer," HTC can distribute tasks over many computers (e.g., idle desktop computers, dedicated servers, or cloud-based resources). HTC facilities exist at many academic and government institutes and are relatively easy to create from commodity hardware. Additionally, consortia such as Open Science Grid facilitate HTC, and commercial entities sell cloud-based solutions for researchers who lack HTC at their institution. We provide an introduction to HTC for biologists and environmental scientists. Our examples from biology and the environmental sciences use HTCondor, an open source HTC system. PMID- 30281591 TI - Comparison of ultrasound imaging and cone-beam computed tomography for examination of the alveolar bone level: A systematic review. AB - BACKGROUND AND OBJECTIVE: The current methods to image alveolar bone in humans include intraoral 2D radiography and cone-beam computed tomography (CBCT). However, these methods expose the subject to ionizing radiation. Therefore, ultrasound imaging has been investigated as an alternative technique, as it is both non-invasive and free from ionizing radiation. In order to assess the validity and reliability of ultrasonography in visualizing alveolar bone, a systematic review was conducted comparing ultrasound imaging to CBCT for examination of the alveolar bone level. STUDY DESIGN: Seven databases were searched. Studies addressing examination of alveolar bone level via CBCT and ultrasound were selected. Risk of bias under Cochrane guidelines was used as a methodological quality assessment tool. RESULTS: All the four included studies were ex vivo studies that used porcine or human cadaver samples. The alveolar bone level was measured by the distance from the alveolar bone crest to certain landmarks such as cemento-enamel junction or gingival margin. The risk of bias was found as low. The mean difference between ultrasound and CBCT measurements ranged from 0.07 mm to 0.68 mm, equivalent to 1.6% - 8.8%. CONCLUSIONS: There is currently preliminary evidence to support the use of ultrasonography as compared to CBCT for the examination of alveolar bone level. Further studies comparing ultrasound to gold standard methods would be necessary to help validate the accuracy of ultrasonography as a diagnostic technique in periodontal imaging. PMID- 30281593 TI - Photosynthesis by marine algae produces sound, contributing to the daytime soundscape on coral reefs. AB - We have observed that marine macroalgae produce sound during photosynthesis. The resultant soundscapes correlate with benthic macroalgal cover across shallow Hawaiian coral reefs during the day, despite the presence of other biological noise. Likely ubiquitous but previously overlooked, this source of ambient biological noise in the coastal ocean is driven by local supersaturation of oxygen near the surface of macroalgal filaments, and the resultant formation and release of oxygen-containing bubbles into the water column. During release, relaxation of the bubble to a spherical shape creates a monopole sound source that 'rings' at the Minnaert frequency. Many such bubbles create a large, distributed sound source over the sea floor. Reef soundscapes contain vast quantities of biological information, making passive acoustic ecosystem evaluation a tantalizing prospect if the sources are known. Our observations introduce the possibility of a general, volumetrically integrative, noninvasive, rapid and remote technique for evaluating algal abundance and rates of primary productivity in littoral aquatic communities. Increased algal cover is one of the strongest indicators for coral reef ecosystem stress. Visually determining variations in algal abundance is a time-consuming and expensive process. This technique could therefore provide a valuable tool for ecosystem management but also for industrial monitoring of primary production, such as in algae-based biofuel synthesis. PMID- 30281594 TI - "I should have started earlier, but I was not feeling ill!" Perceptions of Kalenjin women on antenatal care and its implications on initial access and differentials in patterns of antenatal care utilization in rural Uasin Gishu County Kenya. AB - AIM: The aim of this study was to explore how Kalenjin women in rural Uasing Gishu County in Kenya perceive antenatal care and how their perceptions impede or motivate earlier access and continuous use of antenatal care services. METHODS: A study was conducted among 188 pregnant and post-natal mothers seeking care in 23 rural public health facilities. Gestational age at the initial antenatal care booking was established from their medical cards. Further researcher-administered questionnaire with closed and open-ended questions was used. Key informant interviews with traditional birth attendants (n = 6) and maternal and child health nursing officers (n = 6) were also conducted for triangulation. Descriptive statistics were applied using SPSS programme. The interviews of women who gave consent to be audio recorded (n = 52) were transcribed and thematically analysed using MAXQDA program, based on Andersen and Newman's (1973) behavioural model of health services utilization. RESULTS: The mean gestational age at booking initial biomedical care was 23.36 weeks. Only 18 patients (10%) booked before 13 weeks and 45% made four or more visits. The main reasons given for early booking were: illness in index pregnancy (42%) checking the foetus position and monitoring foetus progress (7%). The main reasons given for late booking were: no reason (31%), was not feeling sick (16%), fear or shame due to unexpected pregnancy (13%). Almost half of the respondents (44%) used both biomedical and traditional antenatal care services. Main reasons for visiting traditional care were to: check foetus position and reposition it (63%), collect medicinal herbs (31%), relief discomforts through massage (18%). CONCLUSION: Early antenatal care booking is meant for women with unpleasant physical signs and symptoms. Later ANC is meant to check foetus position and reposition it to cephalic presentation and monitor its progress and this is only possible if the foetus is large. PMID- 30281595 TI - The Middle Pleistocene (MIS 12) human dental remains from Fontana Ranuccio (Latium) and Visogliano (Friuli-Venezia Giulia), Italy. A comparative high resolution endostructural assessment. AB - The penecontemporaneous Middle Pleistocene sites of Fontana Ranuccio (Latium) and Visogliano (Friuli-Venezia Giulia), set c. 450 km apart in central and northeastern Italy, respectively, have yielded some among the oldest human fossil remains testifying to a peopling phase of the Italian Peninsula broadly during the glacial MIS 12, a stage associated with one among the harshest climatic conditions in the Northern hemisphere during the entire Quaternary period. Together with the large samples from Atapuerca Sima de los Huesos, Spain, and Caune de l'Arago at Tautavel, France, the remains from Fontana Ranuccio and Visogliano are among the few mid-Middle Pleistocene dental assemblages from Western Europe available for investigating the presence of an early Neanderthal signature in their inner structure. We applied two- three-dimensional techniques of virtual imaging and geometric morphometrics to the high-resolution X-ray microtomography record of the dental remains from these two Italian sites and compared the results to the evidence from a selected number of Pleistocene and extant human specimens/samples from Europe and North Africa. Depending on their preservation quality and on the degree of occlusal wear, we comparatively assessed: (i) the crown enamel and radicular dentine thickness topographic variation of a uniquely represented lower incisor; (ii) the lateral crown tissue proportions of premolars and molars; (iii) the enamel-dentine junction, and (iv) the pulp cavity morphology of all available specimens. Our analyses reveal in both samples a Neanderthal-like inner structural signal, for some aspects also resembling the condition shown by the contemporary assemblage from Atapuerca SH, and clearly distinct from the recent human figures. This study provides additional evidence indicating that an overall Neanderthal morphological dental template was preconfigured in Western Europe at least 430 to 450 ka ago. PMID- 30281596 TI - Preservative effect of Chinese cabbage (Brassica rapa subsp. pekinensis) extract on their molecular docking, antioxidant and antimicrobial properties. AB - This study aimed at investigating the antimicrobial activity of different solvent extracts of Chinese cabbage Brassica rapa subsp. pekinensis (BRARP) and their antioxidant and cytotoxicity properties. Of the different solvents extracts, the chloroform extracts (CE) were significantly inhibited the bacterial pathogens at minimum inhibitory concentration (MIC) of 16.5 mg.mL-1. Biochemical analysis revealed that total phenol (62.6 +/- 0.05 mg GAE.g-1) and flavonoids (27.6 +/- 0.04 mg QE.g-1) were higher in the extracts of BRARP, which resulted in enhanced antioxidant activity in CE. A total of eight dominant compounds were detected in the potent antimicrobial extract from BRARP based on GC-MS analysis. The molecular interactions study revealed that, among the screened compounds the 1,2 benzenedicarboxylic acid and 2,3-dicyanopropionamide interacted with the active site of pathogenicity and survival related protein with lipopolysaccharide (LpxC) with higer binding energy. This work concluded that the 1, 2-Benzenedicarboxylic acid and 2, 3-Dicyanopropionamide from BRARP was reported to be good non cytotoxic and antioxidant antimicrobials against bacterial pathogens. PMID- 30281597 TI - Eprobe mediated RT-qPCR for the detection of leukemia-associated fusion genes. AB - The detection and quantification of leukemia-associated fusion gene transcripts play important roles in the diagnosis and follow-up of leukemias. To establish a standardized method without interlaboratory discrepancies, we developed a novel one-step reverse transcription quantitative PCR (RT-qPCR) assay, called "the Eprobe leukemia assay," for major and minor BCR-ABL1, RUNX1-RUNX1T1, and various isoforms of PML-RARA. This assay is comprised of Eprobes that are exciton controlled hybridization-sensitive fluorescent oligonucleotides. Melting curve analyses were performed on synthetic quantitative standard RNAs with strict quality control. Quantification capacity was evaluated by comparison with TaqMan RT-qPCR using 67 primary leukemia patient samples. The lower limit of detection and the limit of quantification of this assay were less than 31.3 copies/reaction and 62.5 copies/reaction, respectively. This assay correctly detected the fusion genes in samples with 100% sensitivity and specificity. The specificity of the reactions was confirmed by melting curve analyses. The assay detected low-level expression of minor BCR-ABL1 co-expressed with major BCR-ABL1. These results illustrate the feasibility and high accuracy of the Eprobe leukemia assay, even for minimal residual disease monitoring. PMID- 30281598 TI - Typhoid fever outbreak in the Democratic Republic of Congo: Case control and ecological study. AB - During 2011 a large outbreak of typhoid fever affected an estimated 1430 people in Kikwit, Democratic Republic of Congo. The outbreak started in military camps in the city but then spread to the general population. This paper reports the results of an ecological analysis and a case-control study undertaken to examine water and other possible transmission pathways. Attack rates were determined for health areas and risk ratios were estimated with respect to spatial exposures. Approximately 15 months after the outbreak, demographic, environmental and exposure data were collected for 320 cases and 640 controls residing in the worst affected areas, using a structured interview questionnaire. Unadjusted and adjusted odds ratios were estimated. Complete data were available for 956 respondents. Residents of areas with water supplied via gravity on the mains network were at much greater risk of disease acquisition (risk ratio = 6.20, 95%CI 3.39-11.35) than residents of areas not supplied by this mains network. In the case control study, typhoid was found to be associated with ever using tap water from the municipal supply (OR = 4.29, 95% CI 2.20-8.38). Visible urine or faeces in the latrine was also associated with increased risk of typhoid and having chosen a water source because it is protected was negatively associated. Knowledge that washing hands can prevent typhoid fever, and stated habit of handwashing habits before cooking or after toileting was associated with increased risk of disease. However, observed associations between handwashing or plate-sharing with disease risk could very likely be due to recall bias. This outbreak of typhoid fever was strongly associated with drinking water from the municipal drinking water supply, based on the descriptive and analytic epidemiology and the finding of high levels of faecal contamination of drinking water. Future outbreaks of potentially waterborne disease need an integrated response that includes epidemiology and environmental microbiology during early stages of the outbreak. PMID- 30281599 TI - Eldecalcitol is more effective in promoting osteogenesis than alfacalcidol in Cyp27b1-knockout mice. AB - Calcium (Ca) absorption from the intestinal tract is promoted by active vitamin D (1alpha,25D3). Vitamin D not only promotes Ca homeostasis, but it also inhibits bone resorption and promotes osteogenesis, thus playing a role in the maintenance of normal bone metabolism. Because 1alpha,25D3 plays an important role in osteogenesis, vitamin D formulations, such as alfacalcidol (ALF) and eldecalcitol (ELD), are used for treating osteoporosis. While it is known that, in contrast to ALF, ELD is an active ligand that directly acts on bone, the reason for its superior osteogenesis effects is unknown. Cyp27b1-knockout mice (Cyp27b1-/-mice) are congenitally deficient in 1alpha,25D3 and exhibit marked hypocalcemia and high parathyroid hormone levels, resulting in osteodystrophy involving bone hypocalcification and growth plate cartilage hypertrophy. However, because the vitamin D receptor is expressed normally in Cyp27b1-/-mice, they respond normally to 1alpha,25D3. Accordingly, in Cyp27b1-/-mice, the pharmacological effects of exogenously administered active vitamin D derivatives can be analyzed without being affected by 1alpha,25D3. We used Cyp27b1-/-mice to characterize and clarify the superior osteogenic effects of ELD on the bone in comparison with ALF. The results indicated that compared to ALF, ELD strongly induces ECaC2, calbindin D9k, and CYP24A1 in the duodenum, promoting Ca absorption and decreasing the plasma concentration of 1alpha,25D3, resulting in improved osteogenesis. Because bone morphological measurements demonstrated that ELD has stronger effects on bone calcification, trabecular formation, and cancellous bone density than ALF, ELD appears to be a more effective therapeutic agent for treating postmenopausal osteoporosis, in which cancellous bone density decreases markedly. By using Cyp27b1-/-mice, this study was the first to succeed in clarifying the osteogenic effect of ELD without any influence of endogenous 1alpha,25D3. Furthermore, ELD more strongly enhanced bone mineralization, trabecular proliferation, and cancellous bone density than did ALF. Thus, ELD is expected to show an effect on postmenopausal osteoporosis, in which cancellous bone mineral density decreases markedly. In the future, this study may enable the development of next-generation active vitamin D derivatives with higher affinity for bone than ELD. PMID- 30281600 TI - Vancomycin associated acute kidney injury in pediatric patients. AB - INTRODUCTION: Vancomycin associated acute kidney injury (vAKI) is a well known complication in pediatric patients. Identification and characterization of the incidence and risk factors for vAKI in the pediatric population would assist clinicians in potentially preventing or mitigating vAKI. METHODS AND MATERIALS: A 6 year retrospective cohort study was designed. Patients were included if they were < 19 years of age, received vancomycin as inpatients, and had a baseline SCr and one other SCr drawn during and up to 72 hours after the discontinuation of vancomycin. Data collection included patient demographics, vancomycin doses and length of therapy, vancomycin serum concentrations, and concomitant medications. The Kidney Disease Improving Global Outcomes (KDIGO) criteria were used to characterize acute kidney injury. Descriptive statistical methods were used and ordinal logistic regression was employed to determine variables significantly associated with vAKI. RESULTS: A total of 7,095 patients met study criteria (55.4% male, median age 4.1 years (IQR 0.67-11.2 years)). Mechanical ventilation was used in 7.9% (n = 563) and mortality was 4.9% (n = 344). A total of 153 concomitant medications were identified. A median of 5 (IQR 3-7) SCr values were obtained and median SCr prior to vancomycin was 0.39 (IQR 0.28-0.57) mg/dL (CrCl 134+/-58 mL/min/1.73m2). Vancomycin was administered for a median of 2 (IQR 1-3) days (14.9+/-1.6 mg/kg/dose). vAKI was present in 12.2% (n = 862: KDIGO stage 1 (8.30%, n = 589), KDIGO stage 2 (1.94%, n = 138) KDIGO stage 3 (1.89%, n = 134)). Mean vancomycin serum concentration at 6-8 hours after a dose for patients with vAKI (10.7+/-8.9 mg/L) was significantly, but not clinically different for patients with no vAKI (7.5+/-6.3 mg/L). (p<0.05) Ordinal logistic regression identified total dose of vancomycin, vancomycin administration in the intensive care unit, and concomitant medication administration as significant for vAKI. In particular, concomitant administration of several different medications, including nafcillin, clindamycin, and acetazolamide, were noted for strong associations with vAKI. (p<0.05). CONCLUSIONS: Moderate to severe acute kidney injury due to vancomycin is infrequent in children and associated with concomitant medication use and total dose of vancomycin. Serum vancomycin concentrations are not useful predictors of vAKI in the pediatric population.

AB - The question of cognitive complexity in early Homo sapiens in North Africa is intimately tied to the emergence of the Aterian culture (~145 ka). One of the diagnostic indicators of cognitive complexity is the presence of specialised bone tools, however significant uncertainty remains over the manufacture and use of these artefacts within the Aterian techno-complex. In this paper we report on a bone artefact from Aterian Middle Stone Age (MSA) deposits in Dar es-Soltan 1 cave on the Atlantic coast of Morocco. It comes from a layer that can be securely dated to ~90 ka. The typological characteristics of this tool, which suggest its manufacture and use as a bone knife, are comparatively similar to other bone artefacts from dated Aterian levels at the nearby site of El Mnasra and significantly different from any other African MSA bone technology. The new find from Dar es-Soltan 1 cave combined with those from El Mnasra suggest the development of a bone technology unique to the Aterian. PMID- 30281601 TI - Learning-induced ribosomal RNA is required for memory consolidation in mice Evidence of differentially expressed rRNA variants in learning and memory. AB - The transition from short-term to long-term forms of synaptic plasticity requires protein synthesis and new gene expression. Most efforts to understand experience induced changes in neuronal gene expression have focused on the transcription products of RNA polymerase II-primarily mRNAs and the proteins they encode. We recently showed that nucleolar integrity and activity-dependent ribosomal RNA (rRNA) synthesis are essential for the maintenance of hippocampal long-term potentiation (LTP). Consequently, the synaptic plasticity and memory hypothesis predicts that nucleolar integrity and activity dependent rRNA synthesis would be required for Long-term memory (LTM). We tested this prediction using the hippocampus-dependent, Active Place Avoidance (APA) spatial memory task and found that training induces de novo rRNA synthesis in mouse dorsal hippocampus. This learning-induced increase in nucleolar activity and rRNA synthesis persists at least 24 h after training. In addition, intra-hippocampal injection of the Pol I specific inhibitor, CX-5461 prior to training, revealed that de novo rRNA synthesis is required for 24 h memory, but not for learning. Using qPCR to assess activity-dependent changes in gene expression, we found that of seven known rRNA expression variants (v-rRNAs), only one, v-rRNA IV, is significantly upregulated right after training. These data indicate that learning induced v-rRNAs are crucial for LTM, and constitute the first evidence that differential rRNA gene expression plays a role in memory. PMID- 30281603 TI - Informed consent learning: Needs and preferences in medical clerkship environments. AB - PURPOSE: Limited information exists regarding students' routine educational needs in support of ethics and professionalism practices faced in real clinical practice. As such the authors aimed to explore medical students learning needs and preferences for informed consent and relevant ethical issues in the clerkship environments. MATERIALS AND METHODS: A cross-sectional study using a self administered, printed survey distributed to final year clinical clerks. RESULTS: 84% completed the survey. Students indicated the need for more attention to all topics related to informed consent (mean = 7.1 on a scale of 0 to 9; +/-1.2). Most additional instructional attention was requested for topics raised in discussions with patients concerning the risks, benefits and alternatives to recommended treatments (7.3 +/-1.4). The cohort expressed the need for education in the care of vulnerable patients (7.2 +/-1.2) with a maximum score for the care of abused children. Women perceived greater need for education concerning informed consent than male respondents (p>0.05). There were significant differences between students who scored high or low on the item "being treated in professional manner" and "endorsement of educational needs for care of adolescents" (p = 0.05). CONCLUSION: There was heightened perception among final year medical students of the need for greater attention to be paid to informed consent education. PMID- 30281604 TI - Oral cholera vaccine coverage during a preventive door-to-door mass vaccination campaign in Nampula, Mozambique. AB - BACKGROUND: In addition to improving water, sanitation and hygiene (WASH) measures and optimal case management, the introduction of Oral cholera vaccine (OCV) is a complementary strategy for cholera prevention and control for vulnerable population groups. In October 2016, the Mozambique Ministry of Health implemented a mass vaccination campaign using a two-dose regimen of the ShancholTM OCV in six high-risk neighborhoods of Nampula city, in Northern Mozambique. Overall 193,403 people were targeted by the campaign, which used a door-to-door strategy. During campaign follow-up, a population survey was conducted to assess: (1) OCV coverage; (2) frequency of adverse events following immunization; (3) vaccine acceptability and (4) reasons for non-vaccination. METHODOLOGY/PRINCIPAL FINDINGS: In the absence of a household listing and clear administrative neighborhood delimitations, we used geospatial technology to select households from satellite images and used the support of community leaders. One person per household was randomly selected for interview. In total, 636 individuals were enrolled in the survey. The overall vaccination coverage with at least one dose (including card and oral reporting) was 69.5% (95%CI: 51.2 88.2) and the two-dose coverage was 51.2% (95%CI: 37.9-64.3). The campaign was well accepted. Among the 185 non-vaccinated individuals, 83 (44.6%) did not take the vaccine because they were absent when the vaccination team visited their houses. Among the 451 vaccinated individuals, 47 (10%) reported minor and non specific complaints, and 78 (17.3%) mentioned they did not receive any information before the campaign. CONCLUSIONS/SIGNIFICANCE: In spite of overall coverage being slightly lower than expected, the use of a mobile door-to-door strategy remains a viable option even in densely-populated urban settings. Our results suggest that campaigns can be successfully implemented and well accepted in Mozambique in non-emergency contexts in order to prevent cholera outbreaks. These findings are encouraging and complement the previous Mozambican experience related to OCV. PMID- 30281605 TI - A prospective matched study on symptomatic dengue in pregnancy. AB - Dengue fever is an increasing problem worldwide, but consequences during pregnancy remain unclear. Much of the available literature suffers from methodological biases that compromise the validity of clinical recommendations. We conducted a matched cohort study during an epidemic in French Guiana to compare events and pregnancy outcomes between two paired groups of pregnant women: women having presented with symptomatic dengue during pregnancy (n = 73) and women having had neither fever nor dengue during pregnancy (n = 219). Women in each arm were matched by place of follow up, gestation weeks at inclusion, and place of residence. Dengue infection was considered to be confirmed if viral RNA, N S1 antigen, the seroconversion of IgM antibodies or the presence of IgM was detected in collected samples. According to the 2009 WHO classification, 27% of the women with symptomatic dengue had at least one clinical or biological warning sign. These complications occurred after the 28th week of gestation in 55% of cases. The medical history, socioeconomic status and demographic characteristics were included in multivariate analysis. Exposure to dengue during pregnancy was not significantly associated with prematurity, small for gestational age infants, hypertension or emergency caesarian section. Maternal dengue with warning signs was a risk factor for peripartum hemorrhage with adjusted relative risk = 8.6(95% CI = 1.2-62). There was a near significant association between dengue and in utero death (p = 0.09). This prospective comparative study underlined the importance of taking into account potential confounders between exposure to dengue and the occurrence of obstetrical events. It also confirms the need for increased vigilance for pregnant women with dengue, particularly for women who present with severe dengue. PMID- 30281606 TI - Receiving a hug is associated with the attenuation of negative mood that occurs on days with interpersonal conflict. AB - Interpersonal touch is emerging as an important topic in the study of adult relationships, with recent research showing that such behaviors can promote better relationship functioning and individual well-being. This investigation considers whether being hugged is associated with reduced conflict-related decreases in positive affect and increases in negative affect as well as whether these associations differ between women and men. A sample of 404 adults were interviewed every night for 14 consecutive days about their conflicts, hug receipt, and positive and negative affect. Results indicated that there was an interaction between hug receipt and conflict exposure such that receiving a hug was associated with a smaller conflict-related decrease in positive affect and a smaller conflict-related increase in negative affect when assessed concurrently. Hug receipt was also prospectively associated with a smaller conflict-related increase in next day negative affect but was not associated with next day positive affect. Associations between hug receipt and conflict-related changes in affect did not differ between women and men, between individuals who were married or in a marital-like relationship and those who were not, or as a function of individual differences in baseline perceived social support. While correlational, these results are consistent with the hypothesis that hugs buffer against deleterious changes in affect associated with experiencing interpersonal conflict. Possible mechanisms through which hugs facilitate positive adaptation to conflict are discussed. PMID- 30281607 TI - Conditioned increase of locomotor activity induced by haloperidol. AB - Dopamine antagonist drugs have profound effects on locomotor activity. In particular, the administration of the D2 antagonist haloperidol produces a state that is similar to catalepsy. In order to confirm whether the modulation of the dopaminergic activity produced by haloperidol can act as an unconditioned stimulus, we carried out two experiments in which the administration of haloperidol was repeatedly paired with the presence of distinctive contextual cues that served as a Conditioned Stimulus. Paradoxically, the results revealed a dose-dependent increase in locomotor activity following conditioning with dopamine antagonist (Experiments 1) that was susceptible of extinction when the conditioned stimulus was presented repeatedly by itself after conditioning (Experiment 2). These data are interpreted from an associative perspective, considering them as a result of a classical conditioning process. PMID- 30281608 TI - Evaluation of a set of refolded recombinant antigens for serodiagnosis of human fascioliasis. AB - Diagnosis of fascioliasis with high sensitivity and specificity antigens play a vital role in the management of the disease. Majority of commercial serological tests use F. hepatica native antigens and indicate wide diversities in test accuracy. Nowadays, recombinant antigens have been introduced as diagnostic reagents offer better test standardization. A combination of highly pure recombinant antigens associated with correct folding will leads to improve specificity and sensitivity of ELISA for diagnosis of Fascioliasis. In this article, Fasciola hepatica saposin-like protein 2 (SAP-2), ferritin protein (Ftn 1) and leucine aminopeptidase (LAP) recombinant antigens were considered as tools for the detection of F. hepatica immunoglobulin G antibodies in persons with chronic human fasciolasis. The recombinant antigens were obtained as fusion proteins, expressed in Escherichia coli and purified by immobilized metal affinity chromatography (IMAC). The refolding processes of denatured recombinant proteins were performed using dialysis method in the presence of chemical additives, and reduced/oxidized glutathione (in vitro). The immunoreactivity of the recombinant antigens was assessed individually and in a combination compared with excretory/secretory antigen (E/S) in an enzyme-linked immunosorbent assay (ELISA) test. The experiments were optimized using 213 serum samples from humans, including patients with chronic fascioliasis, patients with other parasitic diseases, and healthy subjects. The results indicated 95% sensitivity and 98% specificity for rtFhSAP-2, 96% sensitivity and 91% specificity for E/S, 80% and 83.3% for rtFhFtn-1, 84% and 88% for FhLAP, and also, 96% and 95% for combination of recombinant antigens, respectively. In conclusion, the results of this investigation showed that rtFhSAP-2 with the highest specificity and acceptable sensitivity has a considerable superiority compared to mentioned antigens and even in combination with these antigens in serodiagnosis of human fascioliasis. PMID- 30281609 TI - Thismia kelabitiana (Thismiaceae), a new unique Fairy Lantern from Borneo potentially threatened by commercial logging. AB - Thismia kelabitiana, a new unique species from the Sarawak state of Malaysia in the island of Borneo is described and illustrated. This new species is not similar to any species of Thismia described so far especially by having a unique form of mitre and outer perianth lobes deeply divided into 8-10 acute lobes and forming striking fringe around perianth tube opening. The species appears to be critically endangered due to ongoing logging activities in the region. It may potentially become a surrogate species for lower montane forests of the region and thus help protect them against further destruction. PMID- 30281611 TI - Turbulent particle pair diffusion: A theory based on local and non-local diffusional processes. AB - A re-appraisal of the Richardson's 1926 dataset [Richardson, L. F. Proc. Roy. Soc. Lond. A 100, 709-737, (1926)] displays an unequivocal non-local scaling for the pair diffusion coefficient, [Formula: see text], quite different to the previously assumed locality scaling law [Formula: see text], where sigmal is the pair separation. Consequently, the foundations of turbulent pair diffusion theory are re-examined here and it is shown that pair diffusion is governed by both local and non-local diffusional processess inside the inertial subrange. In the context of generalised energy spectra, E(k) ~ k-p for 1 < p <= 3, the new theory predicts two non-Richardson regimes depending on the size of the inertial subrange: (1) in the limit of asymptotically infinite subrange, non-local scaling laws is obtained, [Formula: see text], with gamma intermediate between the purely local and the purely non-local scalings, i.e. (1 + p)/2 < gamma <= 2; and (2) for finite (short) inertial subrange, local scaling laws are obtained, [Formula: see text]. The theory features a novel mathematical approach expressing the pair diffusion coefficient through a Fourier integral decomposition. PMID- 30281610 TI - Widespread detections of neonicotinoid contaminants in central Wisconsin groundwater. AB - Neonicotinoids are a popular and widely-used class of insecticides whose heavy usage rates and purported negative impacts on bees and other beneficial insects has led to questions about their mobility and accumulation in the environment. Neonicotinoid compounds are currently registered for over 140 different crop uses in the United States, with commercial growers continuing to rely heavily on neonicotinoid insecticides for the control of key insect pests through a combination of in-ground and foliar applications. In 2008, the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) began testing for neonicotinoids in groundwater test wells in the state, reporting detections of one or more neonicotinoids in dozens of shallow groundwater test wells. In 2011, similar detection levels were confirmed in several high-capacity overhead center-pivot irrigation systems in central Wisconsin. The current study was initiated to investigate the spatial extent and magnitude of neonicotinoid contamination in groundwater in and around areas of irrigated commercial agriculture in central Wisconsin. From 2013-2015 a total of 317 samples were collected from 91 unique high-capacity irrigation wells and tested for the presence of thiamethoxam (TMX), a neonicotinoid, using enzyme-linked immunosorbent assays. 67% of all samples were positive for TMX at a concentration above the analytical limit of quantification (0.05 MUg/L) and 78% of all wells tested positive at least once. Mean detection was 0.28 MUg/L, with a maximum detection of 1.67 MUg/L. Five wells had at least one detection exceeding 1.00 MUg/L. Furthermore, an analysis of the spatial structure of these well detects suggests that contamination profiles vary across the landscape, with differences in mean detection levels observed from landscape (25 km), to farm (5 km), to individual well (500 m) scales. We also provide an update of DATCP's neonicotinoid monitoring in Wisconsin's shallow groundwater test wells and private potable wells for the years 2011-2017. PMID- 30281612 TI - Mechanism of sea-ice expansion in the Indian Ocean sector of Antarctica: Insights from satellite observation and model reanalysis. AB - In the backdrop of global warming, Antarctic sea-ice variability showed an overall expansion with the regional heterogeneity of increasing and decreasing patterns. Analysis of satellite derived sea-ice extent, during 1979 to 2015, in the Indian Ocean sector of Antarctica (IOA) revealed expansion of 2.4+/-1.2% decade-1. We find strengthening of westerly wind during the austral summer (between 50 degrees S to 62 degrees S) facilitated northward advection of a cool and fresh layer. Also, the strong westerly wind cools the upper ocean due to net heat loss from the ocean surface. The combined effect of northward advection of cold fresh layer and net heat loss from the surface, favours sea-ice expansion in the subsequent seasons, in the IOA region, north of 62 degrees S. However, sea ice retreat was observed near the Kerguelen Plateau, due to upper ocean warming, and hence a non-annular pattern of sea-ice extent in the IOA was observed. PMID- 30281613 TI - In patients with unilateral pleural effusion, restricted lung inflation is the principal predictor of increased dyspnoea. AB - BACKGROUND AND OBJECTIVE: The mechanism of dyspnoea associated with pleural effusion is uncertain. A cohort of patients requiring thoracoscopy for unilateral exudative effusion were investigated for associations between dyspnoea and suggested predictors: impaired ipsilateral diaphragm movement, effusion volume and restricted lung inflation. METHODS: Baseline Dyspnoea Index, respiratory function, and ultrasound assessment of ipsilateral diaphragm movement were assessed prior to thoracoscopy, when effusion volume was measured. Transitional Dyspnoea Index (change from baseline) was assessed 4 and 8 weeks after thoracoscopy. Pearson product moment assessed bivariate correlations and a general linear model examined how well total lung capacity (measuring restricted lung inflation), effusion volume and impaired diaphragm movement predicted Baseline Dyspnoea Index. Un-paired t tests compared the groups with normal and impaired diaphragm movement. RESULTS: 19 patients were studied (14 malignant etiology). Total lung capacity was associated with Baseline Dyspnoea Index (r = 0.68, P = 0.003). Effusion volume (r = -0.138, P = 0.60) and diaphragm movement (P = 0.09) were not associated with Baseline Dyspnoea Index. Effusion volume was larger with impaired diaphragm movement compared to normal diaphragm movement (2.16 +/-SD 0.95 vs.1.16 +/-0.92 L, P = 0.009). Total lung capacity was lower with impaired diaphragm movement compared to normal diaphragm movement (65.4 +/ 10.3 vs 78.2 +/-8.6% predicted, P = 0.011). The optimal general linear model to predict Baseline Dyspnoea Index used total lung capacity alone (adjusted R2 = 0.42, P = 0.003). In nine participants with controlled effusion, baseline effusion volume (r = 0.775, P = 0.014) and total lung capacity (r = -0.690, P = 0.040) were associated with Transitional Dyspnoea Index. CONCLUSIONS: Restricted lung inflation was the principal predictor of increased dyspnoea prior to thoracoscopic drainage of effusion, with no independent additional association with either effusion volume or impaired ipsilateral diaphragm movement. Restricted lung inflation may be an important determinant of the dyspnoea associated with pleural effusion. PMID- 30281614 TI - Automated tube voltage selection in pediatric non-contrast chest CT. AB - BACKGROUND: Modern CT scanners provide automatic dose adjustment systems, which are promising options for reducing radiation dose in pediatric CT scans. Their impact on patient dose, however, has not been investigated sufficiently thus far. OBJECTIVE: To evaluate automated tube voltage selection (ATVS) in combination with automated tube current modulation (ATCM) in non-contrast pediatric chest CT, with regard to the diagnostic image quality. MATERIALS AND METHODS: There were 160 non-contrast pediatric chest CT scans (8.7+/-5.4 years) analyzed retrospectively without and with ATVS. Correlations of volume CT Dose Index (CTDIvol) and effective diameter, with and without ATVS, were compared using Fisher's z-transformation. Image quality was assessed by mean signal-difference to-noise ratios (SDNR) in the aorta and in the left main bronchus using the independent samples t-test. Two pediatric radiologists and a general radiologist rated overall subjective Image quality. Readers' agreement was assessed using weighted kappa coefficients. A p value <0.05 was considered significant. RESULTS: CTDIvol correlation with the effective diameter was r = 0.62 without and r = 0.80 with ATVS (CI: -0.04 to -0.60; p = 0.025). Mean SDNR was 10.88 without and 10.03 with ATVS (p = 0.0089). Readers' agreement improved with ATVS (weighted kappa between pediatric radiologists from 0.1 (0.03-0.16) to 0.27 (0.09-0.45) with ATVS; between general and each pediatric radiologist from 0.1 (0.06-0.14) to 0.12 (0.05-0.20), and from 0.22 (0.11-0.34) to 0.36 (0.24-0.49)). CONCLUSION: ATVS, combined with ATCM, results in a radiation dose reduction for pediatric non contrast chest CT without a loss of diagnostic image quality and prevents errors in manual tube voltage setting, and thus protecting larger children against an unnecessarily high radiation exposure. PMID- 30281615 TI - Efficacy and safety of 5 alpha-reductase inhibitor monotherapy in patients with benign prostatic hyperplasia: A meta-analysis. AB - BACKGROUND: Although combination therapy with 5 alpha-reductase inhibitor (5ARI) and alpha-blocker is one of the standard interventions in symptomatic benign prostatic hyperplasia (BPH), 5ARI monotherapy is seldom the focus of attention. Adverse events associated with 5ARI include depression and suicidal attempts in addition to persistent erectile dysfunction. The aim of this study is to update our knowledge of clinical efficacy and incidence of adverse events associated with 5ARI treatment in symptomatic BPH. METHODS AND FINDINGS: A meta-analysis of randomized controlled clinical trials (RCTs) from 1966 until March, 2017 was performed using database from PubMed, Cochrane Collaboration and Embase. A total of 23395 patients were included in this study and the inclusion criteria were: RCTs with 5ARI and placebo in symptomatic BPH patients. Parameters included prostate specific antigen (PSA), prostate volume (PV), International Prostate Symptom Score (IPPS), post-void residual urine (PVR), voiding symptoms of IPSS (voiding IPSS), maximum urinary flow rate (Qmax), and adverse events (AEs). A meta-analysis with meta-regression was performed for each effect size and adverse events, sensitivity analysis, cumulative analysis along with the analysis of ratio of means (ROM) in the placebo group. A total of 42 studies were included in this study for review, and a total of 37 studies were included in the meta analysis, including a total of 23395 patients (treatment group: 11392, placebo group: 12003). The effect size of all variables except PVR showed a significant improvement following 5ARI treatment compared with placebo. However, the effect size of differences showed declining trend in PV, IPSS and Qmax according to recent years of publication. In ROM analysis, PV showed no significant increase in the placebo group, with a ROM of 1.00 (95% CI, 0.88, 1.14). The 5ARI treatment resulted in a significantly higher incidence of decreased libido (OR = 1.7; 95% CI, 1.36, 2.13), ejaculatory disorder (OR = 2.94; 95% CI, 2.15, 4.03), gynecomastia (OR = 2.32; 95% CI, 1.41, 3.83), and impotence (OR = 1.74; 95% CI, 1.32, 2.29). Our study has the following limitations: included studies were heterogeneous and direct comparison of efficacy between alpha blocker and 5ARI was not performed. Adverse events including depression or suicidal attempt could not be analyzed in this meta-analysis setting. CONCLUSIONS: Although there was a significant clinical benefit of 5ARI monotherapy compared with placebo, the effective size was small. Moreover, the risk of adverse events including sexually related complications were high. Additional head-to-head studies are needed to re evaluate the clinical efficacy of 5ARI compared with alpha-adrenergic receptor blockers. PMID- 30281616 TI - HCV seroconversion in a cohort of people who use drugs followed in a mobile harm reduction unit in Madrid: Breaking barriers for HCV elimination. AB - BACKGROUND AND AIMS: Harm reduction strategies have been shown to decrease the incidence of human immunodeficiency virus (HIV) infection in people who inject drugs (PWID), but the results have been inconsistent when it comes to prevention of hepatitis C virus (HCV) infection. We aimed to examine the rate of HCV seroconversion among people who use drugs (PWUD) followed at a mobile harm reduction unit (MHRU) to evaluate if a low-threshold methadone substitution program (LTMSP) is associated with a low HCV seroconversion rate and subsequently identify barriers for elimination. MATERIALS AND METHODS: A cohort of PWUD have been followed at a MRHU in Madrid between 2013 and 2016. Individuals who were negative for HCV antibodies at baseline and who had at least one retest for HCV antibodies were eligible. Kaplan-Meier methods were employed to estimate the global incidence density. RESULTS: During the study period, 946 PWUD were screened for HCV at least once. At baseline 127 PWUD were negative for HCV antibodies and had at least one follow-up HCV antibodies test. The baseline HCV prevalence was 33%. After a median 0.89 (IQR 0.3-1.5) years of follow-up and 135 person-years of risk for HCV infection, 28 subjects seroconverted. The incidence density for HCV seroconversion for this sample was 20.7 cases (95% CI: 14.3-29.7) per 100 person-years. Injecting drugs in the last year was strongly associated to HCV seroconversion (AHR 15.5, 95%CI 4.3-55.8, p < 0.001). Methadone status was not associated to HCV seroconversion. CONCLUSIONS: A high incidence of HCV infection was found among PWUD at a MHRU in Madrid. In this setting opiate substitutive treatment (OST) as a LTMSP does not appear to protect against HCV seroconversion. PMID- 30281617 TI - Neurodevelopmental disorder-associated ZBTB20 gene variants affect dendritic and synaptic structure. AB - Dendritic spine morphology and dendritic arborization are key determinants of neuronal connectivity and play critical roles in learning, memory and behavior function. Recently, defects of ZBTB20, a BTB and zinc finger domain containing transcriptional repressor, have been implicated in a wide range of neurodevelopmental disorders, including intellectual disability and autism. Here we show distinct effects of expression of two major isoforms, long and short, of ZBTB20, and its neurodevelopmental disorder-linked variants, on dendritic architecture of cultured rat cortical pyramidal neurons. The N-terminal of ZBTB20 showed a role in regulating dendritic spine morphology. Two ZBTB20 single nucleotide variants, located at the N-terminal and central regions of the protein and potentially conferring autism risk, altered dendritic spine morphology. In contrast, a single nucleotide variant identified in patients with intellectual disability and located at the C-terminus of ZBTB20 affected dendritic arborization and dendritic length but had no effect on dendritic spine morphology. Furthermore, truncation of the extreme C-terminus of ZBTB20 caused spine and dendritic morphological changes that were similar but distinct from those caused by the C-terminal variant. Taken together, our study suggests ZBTB20's role in dendritic and synaptic structure and provide possible mechanisms of its effect in neurodevelopmental disorders. PMID- 30281619 TI - Antibacterial effects of nano-imprinted moth-eye film in practical settings. AB - BACKGROUND: Recent studies report that surfaces displaying micrometer- or nanometer-sized undulating structures exhibit antibacterial effects. In previous work, we described the use of an advanced nanofabrication technique to generate an artificial biomimetic Moth-eye film by coating a polyethylene terephthalate (PET) film with nanoscale moth-eye protrusions made from a hydrophilic resin. This moth-eye film exhibited enhanced antibacterial effects in in vitro experiments. The aim of the present study was to verify the antibacterial efficacy of the Moth-eye film in practical environments. MATERIALS AND METHODS: The antibacterial effects of three types of film (Moth-eye film, Flat film, and PET film) were compared. Sample films were pasted onto hand washing basins at the testing locations. After several hours, bacteria were collected from the surface of the sample films with one of three kinds of culture media stamper (to permit identification of bacterial species). The stampers were incubated for 48 hours at 35 degrees C, and the numbers of colonies were counted. RESULTS AND DISCUSSION: The number of common bacteria including E. coli and S. aureus obtained from the Moth-eye film was significantly lower than those from the PET film (p<0.05) and Flat film at 1 hour (p<0.05). This study found that the Moth-eye film showed a long-term (6h) antibacterial effect and the Moth-eye structure (PET coated with nanoscale cone-shaped pillars) demonstrated a physical antibacterial effect from earlier time points. Therefore, the Moth-eye film appears to have potential general-purpose applications in practical environments. PMID- 30281620 TI - A four-stage DEA-based efficiency evaluation of public hospitals in China after the implementation of new medical reforms. AB - This study applied the non-parametric four-stage data envelopment analysis method (Four-Stage DEA) to measure the relative efficiencies of Chinese public hospitals from 2010 to 2016, and to determine how efficiencies were affected by eight factors. A sample of public hospitals (n = 84) was selected from Chongqing, China, including general hospitals and traditional Chinese medicine hospitals graded level 2 or above. The Four-Stage-DEA method was chosen since it enables the control of the impact of environment factors on efficiency evaluation results. Data on the number of staff, government financial subsidies, the number of beds and fixed assets were used as input whereas the number of out-patients and emergency department patients and visits, the number of discharged patients, medical and health service income and hospital bed utilization rate were chosen as study outputs. As relevant environmental variables, we selected GDP per capita, permanent population, population density, number of hospitals and number of available sickbeds in local medical institutions. The relative efficiencies (i.e. technical, pure technical, scale) of sample hospitals were also calculated to analyze the change between the first stage and fourth stage every year. The study found that Four-Stage-DEA can effectively filter the impact of environmental factors on evaluation results, which sets it apart from other models commonly used in existing studies. PMID- 30281618 TI - Prevalence, incidence, predictors, treatment, and control of hypertension among HIV-positive adults on antiretroviral treatment in public sector treatment programs in South Africa. AB - BACKGROUND: One of the key risk factors for cardiovascular disease is hypertension. Hypertension, which leads to heart attacks and strokes, already affects one billion people worldwide, making it a global public health issue. Incidence and prevalence of the condition is on the rise in low- and middle income countries, with the biggest increase in sub-Saharan Africa and South Africa at the forefront. We examined the prevalence, incidence, predictors, treatment, and control of hypertension among HIV-positive patients on ART in a large South African observational cohort. METHODS: We conducted a prospective study of ART naive adults initiating ART at a public sector HIV clinic in South Africa between April 2004-2017. Patients with diagnosed hypertension at ART initiation were excluded from the incidence analysis. Log-binomial regression was used to estimate predictors of hypertension at ART initiation, while competing risks regression was used to evaluate the relationship between predictors of incident hypertension, accounting for death as a competing risk. RESULTS: Among 77,696 eligible patients, 22.0% had prevalent hypertension at ART initiation. Of the remaining patients with no hypertension at ART initiation, 8,125 incident hypertension cases were diagnosed over the period of follow-up, corresponding to an incident rate of 5.4 per 100 person-years (95% confidence interval (CI): 5.3 5.6). We found patients >=40 years of age and patients with a body mass index (BMI) >=25kg/m2 were at increased risk of both prevalent and incident hypertension. Male patients and those with pre-hypertension at ART initiation had increased hazards of hypertension over the period of follow-up. When assessing the choice of antiretroviral drug in first-line ART, patients initiated on nevirapine were at 27% increased risk of developing hypertension compared to those initiated on efavirenz, while patients who initiated on either zidovudine or stavudine had a 40% increased risk of developing hypertension compared to patients initiated on tenofovir. Patientswith poorer health status at ART initiation (i.e. WHO III/IV stage, low CD4 count, low hemoglobin levels and low BMI) had a decrease risk of prevalent hypertension. We found an inverse relationship in patients with a CD4 count <50 cells/mm3 at ART initiation who had a 25% increased risk of incident hypertension compared to those with a CD4 count >=350 cells/mm3. CONCLUSION: Over 20% of patients in our cohort had hypertension at ART initiation, and 13% of those with normal blood pressure at ART initiation developed hypertension while on ART. Older patients, males, those on nevirapine, zidovudine or stavudine, and those who are overweight/obese should be targeted for frequent blood pressure monitoring and the identification of other cardiovascular risk factors to encourage lifestyle modifications. Additionally, these groups should be offered pharmaceutical therapy to help prevent myocardial infarction, heart failure, stroke, and kidney disease. Further research is needed to determine the level of access and adherence to pharmaceutical treatment for hypertension in this population. Additionally, an HIV-negative comparison population is needed to assess the association of the HIV virus itself with hypertension. PMID- 30281621 TI - A cardiac risk score based on sudomotor function to evaluate cardiovascular autonomic neuropathy in asymptomatic Chinese patients with diabetes mellitus. AB - BACKGROUNDS: Cardiac autonomic neuropathy is a common but always overlooked. More convenient diagnostic methods are needed. HYPOTHESIS: Cardiac autonomic neuropathy risk score evaluated by SUDOSCAN has a fine diagnostic efficacy detecting cardiac autonomic neuropathy. METHODS: This is a cross-sectional study among patients with diabetes mellitus. Subjects undertook SUDOSCAN tests and cardiac autonomic reflex tests, including heart rate variability due to Valsalva maneuver, heart rate response due to deep breathing and heart rate response due to standing up. Presenting 2 abnormal results was defined as cardiac autonomic neuropathy. RESULTS: Subjects with cardiac autonomic neuropathy has significantly higher cardiac autonomic neuropathy risk score (32.88+/-1.60 vs 27.64+/-1.24,P = 0.010). Cardiac autonomic neuropathy risk score was correlated significantly with the heart rate response due to deep breathing(P = 0.004). Multiple regression analysis including significant variables showed an independent association of cardiac autonomic neuropathy risk score and heart rate response due to deep breathing (P = 0.031) and age (P = 0.000). In receiver operating characteristic curve analysis evaluating the relationship between cardiac autonomic neuropathy risk score and cardiac autonomic neuropathy, The cut-off value was 20.5, with the sensitivity of 90.48%, the specificity of 29.5%, and the positive predictive value of 46.9%. In two-step diagnostic methods, Setting 20.5 as the cut-off value of cardiac autonomic neuropathy risk score and abnormal heart rate response due to standing up as the second diagnostic step's positive result, and setting 16.5 as the cut-off value of cardiac autonomic neuropathy risk score and abnormal heart rate response due to deep breathing as the second diagnostic step's positive result, both achieved good diagnostic efficacy. CONCLUSION: Cardiac autonomic neuropathy risk score evaluated by SUDOSCAN is a good screening test for cardiac autonomic neuropathy. The two-step diagnostic methods could be considered as surrogate diagnostic methods. PMID- 30281622 TI - Searching for answers in an uncertain world: Meaning threats lead to increased working memory capacity. AB - The Meaning Maintenance Model posits that individuals seek to resolve uncertainty by searching for patterns in the environment, yet little is known about how this is accomplished. Four studies investigated whether uncertainty has an effect on people's cognitive functioning. In particular, we investigated whether meaning threats lead to increased working memory capacity. In each study, we exposed participants to either an uncertain stimulus used to threaten meaning in past studies, or a control stimulus. Participants then completed a working memory measure, where they either had to recall lists of words (Studies 1, 2), or strings of digits (Studies 3, 4). We used both a frequentist approach and Bayesian analysis to evaluate our findings. Across the four studies, we find a small but consistent effect, where participants in the meaning threat condition show improved performance on the working memory tasks. Overall, our findings were consistent with the hypothesis that working memory capacity increases when people experience a meaning threat, which may help to explain improved pattern recognition. Additionally, our results highlight the value of using a Bayesian analytic approach, particularly when studying phenomena with high variance. PMID- 30281623 TI - Dental anomalies and lesions in Eastern Atlantic harbor seals, Phoca vitulina vitulina (Carnivora, Phocidae), from the German North Sea. AB - Skulls of 1,901 Eastern Atlantic harbor seals (Phoca vitulina vitulina) were systematically studied for externally visible dental anomalies and lesions. The sample comprised 927 males and 974 female individuals, with age at death ranging between 1 week and 25 years. Most of the skulls originated from animals collected in 1988, when the population suffered from a mass mortality event caused by the phocine distemper virus (PDV). Mean age (+/- SD) of females (6.7 +/- 6.4 years) was higher (p = 0.002) than that of males (5.9 +/- 5.2 years). In 264 individuals, one or more teeth were missing either congenitally (n = 26 animals, 1.4%) or due to intravital loss (n = 238 animals, 12.5%). One male exhibited congenital absence of all teeth (anodontia). As this animal had been reported to be almost hairless, the condition was tentatively diagnosed as a case of hypohidrotic ectodermal dysplasia. Males were more frequently (p = 0.002) affected by intravital tooth loss (15.0%) than females (10.2%). Supernumerary teeth were found in 3.4% of the skulls, with females (4.7%) showing hyperodontia more frequently (p < 0.001) than males (1.9%). Fifty-nine individuals (3.1%; 28 males, 31 females, p = 0.84) exhibited abnormal tooth morphology. Tooth fractures were noted in 40 seals (2.1%), with males being more frequently affected than females (p = 0.017). Periapical lesions were diagnosed in 143 skulls, with a tendency (p = 0.05) for males (8.7%) to be more frequently affected than females (6.4%). Enamel hypoplasia was not observed in the study sample. Analyzing the occurrence of dental anomalies and lesions in wild mammals can substantially contribute to an assessment of population health and thereby broaden the basis for effective species conservation and informed management decisions. PMID- 30281624 TI - Decomposition of Ethiopian life expectancy by age and cause of mortality; 1990 2015. AB - Ethiopia's average life expectancy has improved by more than 18 years from 1990 to 2015. This initiated interest to study the gain in life expectancy with respect to age structure and cause of death. Applying a life expectancy decomposition technique on secondary data obtained from the Institute of Health Metrics and Evaluation, the study found that the burden of disease in Ethiopia has declined from 626.18 in 1990 to 225.69 in 2015 per 1000 population measured in age-standardized rate of life years lost. The major causes of burden in 1990; namely lower respiratory tract infections, neonatal disorders, diarrheal diseases and neglected tropical diseases at rates of 89.2, 63.2, 61.2, and 42.2 age standardized years of life lost per 1000 population respectively; have shown a fast decline in 2015. Deaths from neglected tropical disease showed 94.95% reduction, contributing to 5.71(27.30%) years gain in life expectancy followed by lower respiratory tract infection and diarrheal disease contributing about 4.65 years (22.23%) and 1.48 years (7.10%) respectively. On the other hand, about 3.3 (15.73%) years and 6.4 (30.71%) years of increase in life expectancy are achieved through improved longevity in infants and children aged 1-4 years respectively. In conclusion, the study found that reductions in under-five child mortality and decline in burden of major communicable diseases could explain the major gain in life expectancy. However, findings also revealed that the prevalence of non communicable diseases and injuries are on the rise calling for the need to be addressed by the public health system. PMID- 30281625 TI - Evaluation of lung toxicity risk with computed tomography ventilation image for thoracic cancer patients. AB - BACKGROUND: Four-dimensional computed tomography (4D-CT) ventilation is an emerging imaging modality. Functional avoidance of regions according to 4D-CT ventilation may reduce lung toxicity after radiation therapy. This study evaluated associations between 4D-CT ventilation-based dosimetric parameters and clinical outcomes. METHODS: Pre-treatment 4D-CT data were used to retrospectively construct ventilation images for 40 thoracic cancer patients retrospectively. Fifteen patients were treated with conventional radiation therapy, 6 patients with hyperfractionated radiation therapy and 19 patients with stereotactic body radiation therapy (SBRT). Ventilation images were calculated from 4D-CT data using a deformable image registration and Jacobian-based algorithm. Each ventilation map was normalized by converting it to percentile images. Ventilation based dosimetric parameters (Mean Dose, V5 [percent lung volume receiving >=5 Gy], and V20 [percent lung volume receiving >=20 Gy]) were calculated for highly and poorly ventilated regions. To test whether the ventilation-based dosimetric parameters could be used predict radiation pneumonitis of >=Grade 2, the area under the curve (AUC) was determined from the receiver operating characteristic analysis. RESULTS: For Mean Dose, poorly ventilated lung regions in the 0-30% range showed the highest AUC value (0.809; 95% confidence interval [CI], 0.663 0.955). For V20, poorly ventilated lung regions in the 0-20% range had the highest AUC value (0.774; 95% [CI], 0.598-0.915), and for V5, poorly ventilated lung regions in the 0-30% range had the highest AUC value (0.843; 95% [CI], 0.732 0.954). The highest AUC values for Mean Dose, V20, and V5 were obtained in poorly ventilated regions. There were significant differences in all dosimetric parameters between radiation pneumonitis of Grade 1 and Grade >=2. CONCLUSIONS: Poorly ventilated lung regions identified on 4D-CT had higher AUC values than highly ventilated regions, suggesting that functional planning based on poorly ventilated regions may reduce the risk of lung toxicity in radiation therapy. PMID- 30281627 TI - The struggle for existence in the world market ecosystem. AB - The global trade system can be viewed as a dynamic ecosystem in which exporters struggle for resources: the markets in which they export. We can think that the aim of an exporter is to gain the entirety of a market share (say, car imports from the United States). This is similar to the objective of an organism in its attempt to monopolize a given subset of resources in an ecosystem. In this paper, we adopt a multilayer network approach to describe this struggle. We use longitudinal, multiplex data on trade relations, spanning several decades. We connect two countries with a directed link if the source country's appearance in a market correlates with the target country's disappearing, where a market is defined as a country-product combination in a given decade. Each market is a layer in the network. We show that, by analyzing the countries' network roles in each layer, we are able to classify them as out-competing, transitioning or displaced. This classification is a meaningful one: when testing the future export patterns of these countries, we show that out-competing countries have distinctly stronger growth rates than the other two classes. PMID- 30281628 TI - Elevated empathy in adults following childhood trauma. AB - Traumatic events increase the risk of depression, but there is also evidence that adversity can lead to posttraumatic growth, including increased compassion and prosocial behavior. To date there is no empirical research pinpointing childhood trauma to an increase in trait empathy in adulthood. Although somewhat counter intuitive, this might be predicted if trauma not only increases fear of future threat but also renders the individual more sensitive to suffering in others. We explored this possible link using multiple studies, self-report measures, and non clinical samples. Results across samples and measures showed that, on average, adults who reported experiencing a traumatic event in childhood had elevated empathy levels compared to adults who did not experience a traumatic event. Further, the severity of the trauma correlated positively with various components of empathy. These findings suggest that the experience of a childhood trauma increases a person's ability to take the perspective of another and to understand their mental and emotional states, and that this impact is long-standing. Future research needs to test if this is seen on performance measures, and how these findings extend to clinical populations. PMID- 30281626 TI - Systemic treatment with resveratrol reduces the progression of experimental periodontitis and arthritis in rats. AB - Rheumatoid arthritis and periodontitis are chronic inflammatory diseases which has been closely associated due to the nature of immune-inflammatory imbalance response. Resveratrol is a naturall product with biological proprieties that may promote immunomodulatory effects on host response. This study investigated resveratrol continuous administration effect on experimental periodontitis and arthritis progression in rats. Thirty-five rats were assigned to the following groups: 1-experimental arthritis + experimental periodontitis + placebo (RA+EP +PL) (n = 12); 2 -RA+EP+ ibuprofen (RA+PE+IB) (n = 11); 3-RA+EP+ resveratrol (RA+PE+RSV) (n = 11). After euthanasia, the specimens were processed for morphometric analysis of bone loss, and the gingival tissue surrounding the first molar was collected for quantification of inflammatory markers using a Luminex/MAGpix assay and anti-citrullinated protein antibody (ACCPA) levels were measured by ELISA assay. Serum level of rheumatoid factor (RF) was measured by ELISA assay. Paw edema was analyzed using a plethysmometer. Higher bone loss was observed in PL group, when compared to IB and RSV groups. RSV group presented higher IL-4 concentration than PL and IB groups. Resveratrol reduced RF serum levels and both IB and RSV decreased ACCPA gingival levels. Besides, paw swelling level was significantly lower in IB and RSV groups in the 21th day and only in RSV group in the 28th day. Histological analyzes showed smooth articular surface and higher width of the subchondral cortical in RSV group. Resveratrol showed modulatory effect and seems to reduce the inflammatory signs of arthritis and articular damage throughout the time. PMID- 30281629 TI - What you saw is what you will hear: Two new illusions with audiovisual postdictive effects. AB - Neuroscience investigations are most often focused on the prediction of future perception or decisions based on prior brain states or stimulus presentations. However, the brain can also process information retroactively, such that later stimuli impact conscious percepts of the stimuli that have already occurred (called "postdiction"). Postdictive effects have thus far been mostly unimodal (such as apparent motion), and the models for postdiction have accordingly been limited to early sensory regions of one modality. We have discovered two related multimodal illusions in which audition instigates postdictive changes in visual perception. In the first illusion (called the "Illusory Audiovisual Rabbit"), the location of an illusory flash is influenced by an auditory beep-flash pair that follows the perceived illusory flash. In the second illusion (called the "Invisible Audiovisual Rabbit"), a beep-flash pair following a real flash suppresses the perception of the earlier flash. Thus, we showed experimentally that these two effects are influenced significantly by postdiction. The audiovisual rabbit illusions indicate that postdiction can bridge the senses, uncovering a relatively-neglected yet critical type of neural processing underlying perceptual awareness. Furthermore, these two new illusions broaden the Double Flash Illusion, in which a single real flash is doubled by two sounds. Whereas the double flash indicated that audition can create an illusory flash, these rabbit illusions expand audition's influence on vision to the suppression of a real flash and the relocation of an illusory flash. These new additions to auditory-visual interactions indicate a spatio-temporally fine-tuned coupling of the senses to generate perception. PMID- 30281630 TI - Barking mad: The vocalisation of the John Dory, Zeus faber. AB - Studies on the behavioural function of sounds are very rare within heterospecific interactions. John Dory (Zeus faber) is a solitary, predatory fish that produces sound when captured, but has not been documented to vocalize under natural conditions (i.e. in the wild). The present study provides the first in-situ recordings of John Dory vocalisations and correlates them to behavioural response of snapper (Pagrus auratus) a common species found through New Zealand. Vocalisations or 'barks', ranged between 200-600 Hz, with a peak frequency of 312 +/- 10 Hz and averaged 139 +/- 4 milliseconds in length. Baited underwater video (BUV) equipped with hydrophones determined that under natural conditions a John Dory vocalization induced an escape response in snapper present, causing them to exit the area opposite to the position of the John Dory. We speculate that the John Dory vocalisation may be used for territorial display towards both conspecifics and heterospecifics, asserting dominance in the area or heightening predatory status. PMID- 30281631 TI - The twin epidemics: Prevalence of TB/HIV co-infection and its associated factors in Ethiopia; A systematic review and meta-analysis. AB - BACKGROUND: Tuberculosis and HIV/AIDS are the major public health problems in many parts of the world particularly in resource limited countries like Ethiopia. Although studies have been conducted on the prevalence and associated factors of TB / HIV co-infection in Ethiopia, there is no comprehensive data on the magnitude and risk factors at a national and regional levels. Therefore, this review is aimed to summarize the prevalence of TB /HIV co-infection in Ethiopia using meta-analysis based on a systematic review of published articles & grey literatures. METHODS: To conduct this systematic review and meta-analysis, major databases such as Pub Med, Google scholar, CINAHL, Africa Journals Online and Google were systematically searched using search terms. PRISMA guideline was followed in the study. Two authors extracted all necessary data using a standardized data extraction format, and analysis was done using STATA version 11. A Statistical heterogeneity across the studies was evaluated by using Cochran's Q test and I2 statistic. The pooled effect size was conducted in the form of prevalence and associations were measured using odds ratio. Moreover, the univariate meta regression was performed by considering the sample size to determine potential sources of heterogeneity. The Egger's weighted regression and Begg's rank correlation tests were used to assess potential publication biases. RESULTS: This meta-analysis included 21 studies with a total of 12,980 participants. The pooled prevalence of TB / HIV Co-infection was 25.59% (95% CI (20.89%-30.29%). A significant association was found between low CD4 counts (OR: 3.53; 95% CI: 1.55, 8.06), advanced WHO stage (OR: 6.81; 95% CI: 3.91, 11.88) and TB/ HIV/AIDS Co-infection. CONCLUSION: This finding revealed that the magnitude of TB /HIV co-infection in Ethiopia is increasing and deserves special attention. Low CD4 count and advanced WHO stage are contributing factors for dual infection. Establishing mechanisms such as Conducting surveillance to determine HIV burden among TB patients and TB burden among HIV patients, and intensifying the three I's (Intensive case finding, INH Preventive Therapy and Infection control) should be routine work of clinicians. Moreover, early screening & treatment should be provided to those patients with low CD4 count and advanced WHO stage. PMID- 30281632 TI - Physiological, perceptual, and technical responses to continuous and intermittent small-sided games in lacrosse players. AB - PURPOSE: The present study was designed to investigate the influence of two distinct small-sided game (SSG) regimes on physiological, perceptual, and technical parameters in male elite lacrosse players. METHOD: Data were collected in twelve elite male Austrian lacrosse players (25.8 +/- 5.5 years; 80.1 +/- 7.7 kg; 178.5 +/- 6.2 cm). Players' were assigned to an intermittent (SSG-I) or a continuous (SSG-C) SSG regime, respectively. Regimes were equated for total practice time, but not active playing time. SSG data from eight sessions of 3 vs. 3 self-regulated match-play were collected along a 4-week pre-season period. Players' YoYo-Level 1 (YYL1) performance before and after the training intervention was recorded. Further, heart-rate (HR), rating of perceived exertion (RPE), physical activity enjoyment scale (PACES), and technical actions during and after SSG sessions were analyzed. RESULTS: Both SSG regimes showed improvement with medium to very large effect sizes (ES) in YYL1 total distance covered pre- to post-intervention (SSG-C mean-difference +/- SD: 840 +/- 299 m; p = 0.003; d = 1.08; CI = 0.60 to 1.56 and SSG-I: 607 +/- 274 m; p = 0.003; d = 1.25; CI = 0.66 to 1.85 respectively). Higher %HRmax values with very large ES (92 +/- 0.6%; p = 0.002; d = 5.33; CI = 2.78 to 7.88) and time spent in HR zone 4 (1248.0 +/- 122.7 s; p = 0.000; d = 3.43; CI = 2.31 to 4.55) were observed for SSG-C. No differences between regimes were found for any of the assessed technical actions, global RPE, and PACES scores. CONCLUSIONS: Both SSG regimes investigated in this study were effective in improving YYL1 performance. Further, findings indicate that the regime does not influence players' subjective feelings and technical actions in SSG play. However, SSG-I in lacrosse specific training could have additional benefits such as lower signs of fatigue. Further, breaks can be used to give technical and tactical inputs by coaches. PMID- 30281633 TI - Detection and serotyping of dengue viruses in febrile patients consulting at the New-Bell District Hospital in Douala, Cameroon. AB - Arboviruses are a major public health problem worldwide and are predominantly present in intertropical areas. Chikungunya, dengue and zika viruses have been implicated in recent epidemics in Asia, America and Africa. In Cameroon, data on these viruses are fragmentary. The purpose of this study was to determine the frequency of detection of these three viruses in febrile patients in Douala, Cameroon. A cross-sectional and descriptive study was conducted from March to April 2017 at the New-Bell District Hospital in Douala. Blood samples were collected from febrile patients and tested for malaria infections using Rapid Diagnostic test. Plasma harvested was later analyzed for the presence of chikungunya, dengue and zika viruses by a Trioplex real-time RT-PCR at Centre Pasteur of Cameroon. A total of 114 participants were included, of which 63.2% were females, reflecting a sex ratio (female/male) of 1.7. The median age was 26 years, range [0.25-81]. Eight (7%) of the 114 participants were infected with Dengue virus (DENV) among which 5 were identified as serotype 1. No cases of infection by either Zika virus or Chikungunya virus were detected. Three cases of dengue-malaria co-infection (13%) were recorded. No association was found between socio-demographic factors and dengue infection. The phylogenetic analysis of the partial envelope E gene showed that all the five DENV serotype 1 samples belonged to subtype V, similarly to strains from West African countries, particularly those from Nigeria, Senegal and Cote d'Ivoire. This study showed the circulation of DENV serotype 1 in febrile patients and raises the alarm for the establishment of a sustained surveillance system to detect cases and prevent potential outbreaks in Cameroon. The existence of dengue-malaria co-infections suggests that surveillance of arboviruses should not be limited to febrile, non-malarial cases. PMID- 30281634 TI - Dominant malaria vector species in Nigeria: Modelling potential distribution of Anopheles gambiae sensu lato and its siblings with MaxEnt. AB - Malaria is a major infectious disease that still affects nearly half of the world's population. Information on spatial distribution of malaria vector species is needed to improve malaria control efforts. In this study we used Maximum Entropy Model (MaxEnt) to estimate the potential distribution of Anopheles gambiae sensu lato and its siblings: Anopheles gambiae sensu stricto, and Anopheles arabiensis in Nigeria. Species occurrence data collected during the period 1900-2010 was used together with 19 bioclimatic, landuse and terrain variables. Results show that these species are currently widespread across all ecological zones. Temperature fluctuation from mean diurnal temperature range, extreme temperature and precipitation conditions, high humidity in dry season from precipitation during warm months, and land use and land cover dynamics have the greatest influence on the current seasonal distribution of the Anopheles species. MaxEnt performed statistically significantly better than random with AUC approximately 0.7 for estimation of the Anopheles species environmental suitability, distribution and variable importance. This model result can contribute to surveillance efforts and control strategies for malaria eradication. PMID- 30281635 TI - The body inversion effect in chimpanzees (Pan troglodytes). AB - Bodies are important social cues for animals. Body recognition in humans is deteriorated by inversion. This inversion effect suggests the configural processing of bodies, which is different from the processing used for other objects. However, it is not known if this type of body processing exists in non human primates. We tested seven chimpanzees using upright and inverted chimpanzee body stimuli and other stimuli in matching-to-sample tasks to examine the body inversion effect and the body parts that invoke it. Our results reflected the body inversion effect for intact chimpanzee bodies, bodies with complete body contours, and bodies with clear faces but not for the objects and other conditions that did not present complete body contours and clear faces. The results show that chimpanzees share configural body processing with humans and that bodies are special to them compared with other objects. The results also revealed the functions of faces and body contours in configural processing by chimpanzees.

PMID- 30281636 TI - A response surface optimization approach to adjust ionic current conductances of cardiac electrophysiological models. Application to the study of potassium level changes. AB - Cardiac electrophysiological computational models are often developed from previously published models. The new models may incorporate additional features to adapt the model to a different species or may upgrade a specific ionic formulation based on newly available experimental data. A relevant challenge in the development of a new model is the estimation of certain ionic current conductances that cannot be reliably identified from experiments. A common strategy to estimate those conductances is by means of constrained non-linear least-squares optimization. In this work, a novel methodology is proposed for estimation of ionic current conductances of cardiac electrophysiological models by using a response surface approximation-based constrained optimization with trust region management. Polynomial response surfaces of a number of electrophysiological markers were built using statistical sampling methods. These markers included action potential duration (APD), triangulation, diastolic and systolic intracellular calcium concentration, and time constants of APD rate adaptation. The proposed methodology was applied to update the Carro et al. human ventricular action potential model after incorporation of intracellular potassium ([K+]i) dynamics. While the Carro et al. model was well suited for investigation of arrhythmogenesis, it did not allow simulation of [K+]i changes. With the methodology proposed in this study, the updated Carro et al. human ventricular model could be used to simulate [K+]i changes in response to varying extracellular potassium ([K+]o) levels. Additionally, it rendered values of evaluated electrophysiological markers within physiologically plausible ranges. The optimal values of ionic current conductances in the updated model were found in a notably shorter time than with previously proposed methodologies. As a conclusion, the response surface optimization-based approach proposed in this study allows estimating ionic current conductances of cardiac electrophysiological computational models while guaranteeing replication of key electrophysiological features and with an important reduction in computational cost with respect to previously published approaches. The updated Carro et al. model developed in this study is thus suitable for the investigation of arrhythmic risk-related conditions, including those involving large changes in potassium concentration. PMID- 30281639 TI - Dead and buried? Variation in post-mortem histories revealed through histotaphonomic characterisation of human bone from megalithic graves in Sweden. AB - This study investigates possible variation in post-mortem histories during the Neolithic period in southwestern Sweden based on microscopic studies of human bone. Numerous megalithic graves were built in this region and good preservation conditions have left a rich skeletal record. After more than a hundred years of research, it is still a controversy whether or not these skeletal assemblages were the result of primary burials, or ossuaries where skeletonized remains were deposited. In this study we apply histological analysis to obtain insights into post-mortem histories and taphonomic processes affecting the human remains, potentially including funerary rituals. This type of analysis records the condition and traces of degradation found in skeletal material at a microscopic level. Human skeletal material from four different megalithic tombs in the Falbygden area has been sampled and analysed by thin-section light microscopy, and by scanning electron microscopy. The results of the study provide evidence of variation and changes in burial conditions for skeletal remains from the different graves, also for remains from the same grave. Extent of bioerosion varied, from extensive to moderate/arrested, to none. Bone samples from the same graves also differed in the type of staining and mineral inclusions, showing that the non-bioeroded samples relatively early post-mortem must have experienced an anoxic environment, and later a change to an aerated environment. This could be taken as an indication of primary burial somewhere else, but more likely reflect a special micro-environment occurring temporarily in some graves and parts of graves after the tombs were filled with soil and sealed by roof slabs. The study illustrates the usefulness of bone histological analysis in the reconstruction of post-mortem histories, revealing variations not discernible at macro-level that may aid in the interpretations of funerary rituals. However, the results also highlight the issues of equifinality. Based on current data and knowledge, several scenarios are possible. Further histotaphonomic work is advisable, including archaeological remains from megalithic tombs, and bones from taphonomic experiments. PMID- 30281638 TI - Prevalence of childhood obstructive sleep apnea syndrome and its role in daytime sleepiness. AB - OBJECTIVES: To investigate childhood obstructive sleep apnea syndrome (OSAS) and its role in daytime sleepiness among school-age children. METHODS: A questionnaire survey was conducted with 25,211 children aged 6-15 (mean, 10.39) years attending 148 elementary and 71 middle schools in 10 prefectures across Japan and their parents. Questions concerned 4 sleep habit items (bedtime, sleep onset latency, wake time after sleep onset, wake-up time) and 4 sleep disorder items (loud snoring, snorts/gasps, breathing pauses, seems very sleepy in the daytime). Total sleep time (TST) was calculated with sleep habits. Severe possible OSAS (p-OSAS) was defined as having loud snoring, snorts and gasps, or breathing pauses "frequently" (>= 5 times per week), and mild p-OSAS was rated as having any of these "sometimes" (2-4 times per week). Severe daytime sleepiness was defined as seeming very sleepy "frequently" and mild daytime sleepiness as seeming very sleepy "sometimes". RESULTS: Mean prevalence of mild to severe p OSAS and severe p-OSAS in children across all grade levels was 9.5% and 1.6%, respectively. p-OSAS was particularly prevalent in children at lower elementary levels, decreasing with advancing grade levels. Prevalence of mild and severe daytime sleepiness was 6.1% and 0.9%, respectively, among all children (7.0%). Prevalence of daytime sleepiness increased with advancing grade levels, particularly in middle-school level. Average TST was 8.4 +/- 2.2 h in both elementary and middle-school levels, and decreased as grades advanced, particularly in middle-school levels. Multivariate logistic regression analysis showed that middle-school level, TST < 8 h, and p-OSAS were independent factors for daytime sleepiness. Strong correlations were found between severe daytime sleepiness and severe p-OSAS or TST < 6 h, and between daytime sleepiness and loud snoring or breathing pauses. CONCLUSION: p-OSAS may be an independent factor influencing daytime sleepiness in school-age children.

AB - PURPOSE: Systemic inflammation is potentially associated with ocular diseases such as late age-related macular degeneration (AMD). Using the serum concentration of high-sensitive C-reactive protein (hs-CRP) as surrogate of systemic inflammation, we examined potential associations between the serum hs CRP concentration and the presence and degree of eye diseases. METHODS: The population-based Beijing Eye Study included 3468 Chinese individuals. The study participants underwent a standardized interview and a detailed ophthalmic examination. The serum concentration of hs-CRP was determined. RESULTS: Out of 3468 participants, 2452 (70.7%) individuals (mean age:63.4+/-9.4 year; range:50 91 years) had hs-CRP measurements (mean:1.96+/-4.07mg/L). In multivariate analysis, higher serum concentration of hs-CRP was significantly (regression coefficient r: 0.21) associated with a higher level of diabetic retinopathy (P = 0.007; standardized regression coefficient beta:0.06; non-standardized regression coefficient B:1.35; 95% confidence interval (CI):0.37,2.22) and polypoidal choroidal vasculopathy (P = 0.002;beta:0.06;B:6.22;95%CI:2.24,10.2) after adjusting for higher serum concentration of high-density lipoproteins (P<0.001;beta:-0.12;B:-1.31;95%CI:-1.77,-0.85), higher body mass index (P = 0.01;beta:0.06;B:0.06;95%CI:0.01, 0.11), lower level of education (P = 0.04;beta: 0.06;B:-0.22;95%CI:-0.42,-0.02), lower cognitive function score (P = 0.01;beta: 0.07;B:-0.08;95%CI:-0.13,-0.02). If the presences of other ocular diseases were added to the model, the presence of glaucoma (P = 0.99), open-angle glaucoma (P = 0.80), angle-closure glaucoma (P = 0.67), pseudoexfoliation (P = 0.18), nuclear cataract (P = 0.30), cortical cataract (P = 0.15), subcapsular cataract (P = 0.59), retinal vein occlusions (P = 0.33), central serous choroidopathy (P = 0.44), early stage of age-related macular degeneration (AMD) (P = 0.46), intermediate stage of AMD (P = 0.20) and late stage of AMD (P = 0.91) including geographic atrophy (P = 0.60) or neovascular AMD (P = 0.68) were not significantly associated with the serum concentration of hs-CRP. CONCLUSIONS: In Chinese aged 50+ years, higher serum concentration of hs-CRP was significantly associated with a higher level of diabetic retinopathy and higher frequency of polypoidal choroidal vasculopathy. Other major ocular disorders, namely glaucoma including open-angle glaucoma and angle-closure glaucoma, pseudoexfoliation, nuclear, cortical or subcapsular cataract, retinal vein occlusions, central serous choroidopathy, early, intermediate or late stage of AMD including geographic atrophy, were not significantly associated with hs-CRP serum concentrations. It suggests that these diseases, in contrast to diabetic retinopathy and polypoidal choroidal vasculopathy, were not associated with a major systemic inflammatory component.

AB - Naturally occurring entomopathogenic fungi such as Conidiobolus coronatus are important regulatory factors of insect populations. GC-MS analysis of fungal cell free filtrates showed that C. coronatus synthesizes two beta- carboline alkaloids: harman and norharman. Significantly higher levels of both alkaloids are produced by C. coronatus in minimal postincubation medium than in rich medium. The beta-carboline alkaloids may have an effect on the nervous system of insects and their behavior. Harman and norharman were applied to Galleria mellonella larvae (a parasite of honeybees) either topically or mixed with food. Larvae received alkaloids in three concentrations: 750, 1000 or 1250 ppm. The effect on the survival and further development of larvae was examined. Both harman and norharman delayed pupation and adult eclosion, and inhibit total monoamine oxidase activity. In addition, they increased the serotonin concentration and decreased the monoamine oxidase A level in the heads of the moths. It is likely that the alkaloids were metabolized by the insects, as their effect wore off 24 hours after topical application. This is the first study to show that C. coronatus produces alkaloids. Its aim was to identify the actions of beta-carboline alkaloids on insect development and serotonin-regulating enzymes. Knowledge of the potential role of harman and norharman in the process of fungal infection might lead to the development of more effective and environmentally friendly means of controlling insect pests. PMID- 30281643 TI - The acute medical unit model: A characterisation based upon the National Health Service in Scotland. AB - BACKGROUND: Acute medical units (AMUs) receive the majority of acute medical patients presenting to hospital as an emergency in the United Kingdom (UK) and in other international settings. They have emerged as a result of local service innovation in the context of a limited evidence base. As such, the AMU model is not well characterised in terms of its boundaries, patient populations and components of care. This makes service optimisation and development through strategic resource planning, quality improvement and research challenging. AIM: This study aims to evaluate a national set of AMUs with the intent of characterising the AMU model. METHODS: Twenty-nine AMUs in Scotland were identified. Data were collected by semi-structured interviews with multidisciplinary healthcare professionals working in each AMU. A draft report was produced for each unit and verified by a unit representative. The unit reports were then analysed to develop a conceptual framework of key components of AMUs and a service definition of the boundaries of acute medical care. RESULTS: Acute medical care in Scotland can be described as being delivered in "acute medical services" rather than geographically distinct AMUs. Twelve key components of AMU care were identified: care areas, functions, populations, patient flow, support services, communication, nurse care, allied healthcare professional care, non-consultant medical care, consultant care, patient assessment and specialty care. DISCUSSION: This empirically derived characterisation of the AMU model is likely to be of utility to practitioners, managers, policy makers and researchers: it is relevant on an operational level, will aid quality improvement and is a foundation to needed further research into how best to deliver care in AMUs. This is important given the central role AMUs play in the journey of the majority of patients presenting to hospital acutely in Scotland, the UK and internationally. PMID- 30281644 TI - Predictive models for charitable giving using machine learning techniques. AB - Private giving represents more than three fourths of all U.S. charitable donations, about 2% of total Gross Domestic Product (GDP). Private giving is a significant factor in funding the nonprofit sector of the U.S. economy, which accounts for more than 10% of total GDP. Despite the abundance of data available through tax forms and other sources, it is unclear which factors influence private donation, and a reliable predictive mechanism remains elusive. This study aims to develop predictive models to accurately estimate future charitable giving based on a set of potentially influential factors. We have selected several factors, including unemployment rate, household income, poverty level, population, sex, age, ethnicity, education level, and number of vehicles per household. This study sheds light on the relationship between donation and these variables. We use Stepwise Regression to identify the most influential variables among the available variables, based on which predictive models are developed. Multiple Linear Regression (MLR) and machine learning techniques, including Artificial Neural Networks (ANN) and Support Vector Regression (SVR) are used to develop the predictive models. The results suggest that population, education level, and the amount of charitable giving in the previous year are the most significant, independent variables. We propose three predictive models (MLR, ANN, and SVR) and validate them using 10-fold cross-validation method, then evaluate the performance using 9 different measuring criteria. All three models are capable of predicting the amount of future donations in a given region with good accuracy. Based on the evaluation criteria, using a test data set, ANN outperforms SVR and MLR in predicting the amount of charitable giving in the following year. PMID- 30281645 TI - Validation of a genetic risk score for Arkansas women of color. AB - African American women in the state of Arkansas have high breast cancer mortality rates. Breast cancer risk assessment tools developed for African American underestimate breast cancer risk. Combining African American breast cancer associated single-nucleotide polymorphisms (SNPs) into breast cancer risk algorithms may improve individualized estimates of a woman's risk of developing breast cancer and enable improved recommendation of screening and chemoprevention for women at high risk. The goal of this study was to confirm with an independent dataset consisting of Arkansas women of color, whether a genetic risk score derived from common breast cancer susceptibility SNPs can be combined with a clinical risk estimate provided by the Breast Cancer Risk Assessment Tool (BCRAT) to produce a more accurate individualized breast cancer risk estimate. A population-based cohort of African American women representative of Arkansas consisted of 319 cases and 559 controls for this study. Five-year and lifetime risks from the BCRAT were measured and combined with a risk score based on 75 independent susceptibility SNPs in African American women. We used the odds ratio (OR) per adjusted standard deviation to evaluate the improvement in risk estimates produced by combining the polygenic risk score (PRS) with 5-year and lifetime risk scores estimated using BCRAT. For 5-year risk OR per standard deviation increased from 1.84 to 2.08 with the addition of the polygenic risk score and from 1.79 to 2.07 for the lifetime risk score. Reclassification analysis indicated that 13% of cases had their 5-year risk increased above the 1.66% guideline threshold (NRI = 0.020 (95% CI -0.040, 0.080)) and 6.3% of cases had their lifetime risk increased above the 20% guideline threshold by the addition of the polygenic risk score (NRI = 0.034 (95% CI 0.000, 0.070)). Our data confirmed that discriminatory accuracy of BCRAT is improved for African American women in Arkansas with the inclusion of specific SNP breast cancer risk alleles. PMID- 30281646 TI - Loss of Ccbe1 affects cardiac-specification and cardiomyocyte differentiation in mouse embryonic stem cells. AB - Understanding the molecular pathways regulating cardiogenesis is crucial for the early diagnosis of heart diseases and improvement of cardiovascular disease. During normal mammalian cardiac development, collagen and calcium-binding EGF domain-1 (Ccbe1) is expressed in the first and second heart field progenitors as well as in the proepicardium, but its role in early cardiac commitment remains unknown. Here we demonstrate that during mouse embryonic stem cell (ESC) differentiation Ccbe1 is upregulated upon emergence of Isl1- and Nkx2.5- positive cardiac progenitors. Ccbe1 is markedly enriched in Isl1-positive cardiac progenitors isolated from ESCs differentiating in vitro or embryonic hearts developing in vivo. Disruption of Ccbe1 activity by shRNA knockdown or blockade with a neutralizing antibody results in impaired differentiation of embryonic stem cells along the cardiac mesoderm lineage resulting in a decreased expression of mature cardiomyocyte markers. In addition, knockdown of Ccbe1 leads to smaller embryoid bodies. Collectively, our results show that CCBE1 is essential for the commitment of cardiac mesoderm and consequently, for the formation of cardiac myocytes in differentiating mouse ESCs.

PMID- 30281647 TI - Chronic oral application of a periodontal pathogen results in brain inflammation, neurodegeneration and amyloid beta production in wild type mice. AB - BACKGROUND: The results from cross sectional and longitudinal studies show that periodontitis is closely associated with cognitive impairment (CI) and Alzhemer's Disease (AD). Further, studies using animal model of periodontitis and human post mortem brain tissues from subjects with AD strongly suggest that a gram-negative periodontal pathogen, Porphyromonas gingivalis (Pg) and/or its product gingipain is/are translocated to the brain. However, neuropathology resulting from Pg oral application is not known. In this work, we tested the hypothesis that repeated exposure of wild type C57BL/6 mice to orally administered Pg results in neuroinflammation, neurodegeneration, microgliosis, astrogliosis and formation of intra- and extracellular amyloid plaque and neurofibrillary tangles (NFTs) which are pathognomonic signs of AD. METHODS: Experimental chronic periodontitis was induced in ten wild type 8-week old C57BL/6 WT mice by repeated oral application (MWF/week) of Pg/gingipain for 22 weeks (experimental group). Another 10 wild type 8-week old C57BL/6 mice received vehicle alone (control group) MWF per week for 22 weeks. Brain tissues were collected and the presence of Pg/gingipain was determined by immunofluorescence (IF) microscopy, confocal microscopy, and quantitative PCR (qPCR). The hippocampi were examined for the signs of neuropathology related to AD: TNFalpha, IL1beta, and IL6 expression (neuroinflammation), NeuN and Fluoro Jade C staining (neurodegeneration) and amyloid beta1-42 (Abeta42) production and phosphorylation of tau protein at Ser396 were assessed by IF and confocal microscopy. Further, gene expression of amyloid precursor protein (APP), beta-site APP cleaving enzyme 1 (BACE1), a disintegrin and metalloproteinase domain-containing protein10 (ADAM10) for alpha secretase and presenilin1 (PSEN1) for gamma-secretase, and NeuN (rbFox3) were determined by RT-qPCR. Microgliosis and astrogliosis were also determined by IF microscopy. RESULTS: Pg/gingipain was detected in the hippocampi of mice in the experimental group by immunohistochemistry, confocal microscopy, and qPCR confirming the translocation of orally applied Pg to the brain. Pg/gingipain was localized intra-nuclearly and peri-nuclearly in microglia (Iba1+), astrocytes (GFAP+), neurons (NeuN+) and was evident extracellularly. Significantly greater levels of expression of IL6, TNFalpha and IL1beta were evident in experimental as compared to control group (p<0.01, p<0.00001, p<0.00001 respectively). In addition, microgliosis and astrogliosis were evident in the experimental but not in control group (p <0.01, p<0.0001 respectively). Neurodegeneration was evident in the experimental group based on a fewer number of intact neuronal cells assessed by NeuN positivity and rbFOX3 gene expression, and there was a greater number of degenerating neurons in the hippocampi of experimental mice assessed by Fluoro Jade C positivity. APP and BACE1 gene expression were increased in experimental group compared with control group (p<0.05, p<0.001 respectively). PSEN1 gene expression was higher in experimental than control group but the difference was not statistically significant (p = 0.07). ADAM10 gene expression was significantly decreased in experimental group compared with control group (p<0.01). Extracellular Abeta42 was detected in the parenchyma in the experimental but not in the control group (p< 0.00001). Finally, phospho-Tau (Ser396) protein was detected and NFTs were evident in experimental but not in the control group (p<0.00001). CONCLUSIONS: This study is the first to show neurodegeneration and the formation of extracellular Abeta42 in young adult WT mice after repeated oral application of Pg. The neuropathological features observed in this study strongly suggest that low grade chronic periodontal pathogen infection can result in the development of neuropathology that is consistent with that of AD. PMID- 30281648 TI - RAIDD mutations underlie the pathogenesis of thin lissencephaly (TLIS). AB - Abnormal regulation of caspase-2-mediated neuronal cell death causes neurodegenerative diseases and defective brain development. PIDDosome is caspase 2 activating complex composed of PIDD, RAIDD, and caspase-2. Recent whole-exome sequencing study showed that the RAIDD mutations in the death domain (DD), including G128R, F164C, R170C, and R170H mutations, cause thin lissencephaly (TLIS) by reducing caspase-2-mediated neuronal apoptosis. Given that the molecular structure of the RAIDD DD:PIDD DD complex is available, in this study, we analyzed the molecular mechanisms underlying TLIS caused by the RAIDD TLIS variants by performing mutagenesis and biochemical assays. PMID- 30281650 TI - Telomere shortening in breast cancer cells (MCF7) under treatment with low doses of the benzylisoquinoline alkaloid chelidonine. AB - Telomeres, the specialized dynamic structures at chromosome ends, regularly shrink with every replication. Thus, they function as an internal molecular clock counting down the number of cell divisions. However, most cancer cells escape this limitation by activating telomerase, which can maintain telomere length. Previous studies showed that the benzylisoquinoline alkaloid chelidonine stimulates multiple modes of cell death and strongly down-regulates telomerase. It is still unknown if down-regulation of telomerase by chelidonine boosts substantial telomere shortening. The breast cancer cell line MCF7 was sequentially treated with very low concentrations of chelidonine over several cell passages. Telomere length and telomerase activity were measured by a monochrome multiplex quantitative PCR and a q-TRAP assay, respectively. Changes in population size and doubling time correlated well with telomerase inhibition and telomere shortening. MCF7 cell growth was arrested completely after three sequential treatments with 0.1 MUM chelidonine, each ending after 48 h, while telomere length was reduced to almost 10% of the untreated control. However, treatment with 0.01 MUM chelidonine did not have any apparent consequence. In addition to dose and time dependent telomerase inhibition, chelidonine changed the splicing pattern of hTERT towards non-enzyme coding isoforms of the transcript. In conclusion, telomere length and telomere stability are strongly affected by chelidonine in addition to microtubule formation. PMID- 30281651 TI - The influence of hypoxia and prolonged exercise on attentional performance at high and extreme altitudes: A pilot study. AB - INTRODUCTION: Exposure to hypoxic conditions is reported to impair cognitive performance. Further, moderate physical exercise improves cognitive function, but little is known about the influence of exercise on cognitive function in hypoxia. Therefore, the current study aimed to examine the influence of hypoxia (HYP) and prolonged exercise (EX) on attentional performance. METHODS: A total of 80 participants (female: n = 29; male: n = 51) were assigned to four groups: HYP + EX (n = 15), HYP (n = 25), EX (n = 21) and normoxia (NOR) (n = 21). The Frankfurt Attention Inventory-2 (FAIR-2) was performed at four testing points (day 1, 14, 16 and 18) to assess attentional performance. All groups completed a pretest (D1) and a follow-up test (D18). In HYP + EX conditions, the cognitive task was performed in a hypoxic state after prolonged exercise (D14: 3950 m, D16: 5739 m) during a mountain climb on Mt. Kilimanjaro. Participants in HYP were tested under intermittent hypoxia at rest in a hypoxic chamber (D14: 3500 m, D16: 5800 m), and those in EX were tested under normoxia after prolonged exercise during a 7-day backcountry ski hiking tour. NOR was a control group, and participants completed all tests under normoxia and at rest. RESULTS: Hypoxia impaired the attentional functions performance value (PV) and continuity value (CV) for the HYP + EX (p = 0.000) and HYP (L: p = 0.025; K: p = 0.043) groups at 5739 m and 5800 m, respectively, but not the function quality value (QV). In contrast, the EX group did not exhibit changes in attentional function. CONCLUSION: The current results suggest that attentional performance is impaired during extreme normobaric and hypobaric hypoxic exposure. We further conclude that greater cognitive impairment under hypobaric hypoxia during a mountain climb compared with normobaric hypoxia at rest is not caused by prolonged exercise, but may be influenced by other factors (e.g. low temperatures, dehydration, or sleep deprivation) that remain to be verified. PMID- 30281652 TI - Stride-to-stride fluctuations in transtibial amputees are not affected by changes in push-off mechanics from using different prostheses. AB - Stride-to-stride fluctuations of joint kinematics during walking reflect a highly structured organization that is characteristic of healthy gait. The organization of stride-to-stride fluctuations is disturbed in lower-limb prosthesis users, yet the factors contributing to this difference are unclear. One potential contributor to the changes in stride-to-stride fluctuations is the altered push off mechanics experienced by passive prosthesis users. The purpose of our study was to determine if changes in push-off mechanics affect stride-to-stride fluctuations in transtibial amputees. Twenty-two unilateral transtibial amputees were enrolled in the 6-week cross-over study, where High and Low Activity (based on the Medicare Functional Classification System) prostheses were worn for three weeks each. Data collection took place at the end of the third week. Participants walked on a treadmill in a motion capture laboratory to quantify stride-to-stride fluctuations of the lower extremity joint angle trajectories using the largest Lyapunov Exponent, and over floor-embedded force platforms to enable calculating push-off work from the prosthesis and the sound limb. Push-off work was 140% greater in the High Activity prosthesis compared to the Low Activity prosthesis (p < 0.001), however no significant change was observed in stride-to-stride fluctuations of the ankle between the two prosthesis types (p = 0.576). There was no significant correlation between changes in prosthesis push-off work and the largest Lyapunov exponent. Though differences in push-off work were observed between the two prosthesis types, stride-to-stride fluctuations remained similar, indicating that prosthesis propulsion mechanics may not be a strong determinant of stride-to-stride fluctuations in unpowered transtibial prosthesis users. PMID- 30281653 TI - Temporal clustering analysis of endothelial cell gene expression following exposure to a conventional radiotherapy dose fraction using Gaussian process clustering. AB - The vascular endothelium is considered as a key cell compartment for the response to ionizing radiation of normal tissues and tumors, and as a promising target to improve the differential effect of radiotherapy in the future. Following radiation exposure, the global endothelial cell response covers a wide range of gene, miRNA, protein and metabolite expression modifications. Changes occur at the transcriptional, translational and post-translational levels and impact cell phenotype as well as the microenvironment by the production and secretion of soluble factors such as reactive oxygen species, chemokines, cytokines and growth factors. These radiation-induced dynamic modifications of molecular networks may control the endothelial cell phenotype and govern recruitment of immune cells, stressing the importance of clearly understanding the mechanisms which underlie these temporal processes. A wide variety of time series data is commonly used in bioinformatics studies, including gene expression, protein concentrations and metabolomics data. The use of clustering of these data is still an unclear problem. Here, we introduce kernels between Gaussian processes modeling time series, and subsequently introduce a spectral clustering algorithm. We apply the methods to the study of human primary endothelial cells (HUVECs) exposed to a radiotherapy dose fraction (2 Gy). Time windows of differential expressions of 301 genes involved in key cellular processes such as angiogenesis, inflammation, apoptosis, immune response and protein kinase were determined from 12 hours to 3 weeks post-irradiation. Then, 43 temporal clusters corresponding to profiles of similar expressions, including 49 genes out of 301 initially measured, were generated according to the proposed method. Forty-seven transcription factors (TFs) responsible for the expression of clusters of genes were predicted from sequence regulatory elements using the MotifMap system. Their temporal profiles of occurrences were established and clustered. Dynamic network interactions and molecular pathways of TFs and differential genes were finally explored, revealing key node genes and putative important cellular processes involved in tissue infiltration by immune cells following exposure to a radiotherapy dose fraction. PMID- 30281654 TI - Utility of reticulocyte haemoglobin content and percentage hypochromic red cells as markers of iron deficiency anaemia among black CKD patients in South Africa. AB - INTRODUCTION: Iron deficiency anaemia (IDA) worsens the prognosis and outcomes of chronic kidney disease (CKD). However, while the haemoglobin level is unreliable for early detection of IDA, reticulocyte haemoglobin content (CHr) and hypochromic red cells (%HYPO) are early markers of IDA. METHODS: This was a cross sectional study of black adult participants (n = 258) with CKD and apparently healthy members of staff and patients' relatives (n = 141) at the Charlotte Maxeke Johannesburg Academic Hospital, South Africa, between 1 June 2016 and 31 December 2016. Serum iron, serum ferritin and transferrin were measured using standard laboratory methods, while the haematology analyser was employed to measure CHr and %HYPO. The validity of CHr and %HYPO as markers of IDA were evaluated. Multivariable binary logistic regression was conducted to determine predictors of the relationship between IDA, CHr and %HYPO. The area under the receiver operator characteristics (ROC) curve (AUC) of the final models were utilised to evaluate the discriminatory value of CHr and %HYPO respectively. RESULTS: About one-quarter (26.1%) of the participants had IDA which was more than three times more frequent among CKD patients, compared to controls (35.3% vs 9.2%); 32.3% (95%CI: 27.90%- 37.10%) of the study population had iron deficiency without anaemia and the prevalence of iron deficiency without anaemia was lower in CKD patients compared to controls (29.5% vs 37.6%). The mean age of CKD patients was higher than in controls (52.7 +/-14.3 vs 40.4 +/-12.6 years, P value<0.001). The sensitivity and specificity for diagnosing IDA among CKD participants was 62.6% and 80.2% respectively for CHr (at a cut-off value of <28pg) and 63.3% and 79.8% respectively for %HYPO. CKD participants with CHr levels >28pg were 82% less likely to be diagnosed as having IDA as compared to those with CHr levels <= 28pg) (adj odds ratio = 0.18, 95% CI: 0.09-0.37). The AUC of CHr (0.81, 95% CI: 0.76-0.87) was higher than the AUC of %HYPO (0.76, 95%CI: 0.70-0.82). CONCLUSION: The diagnostic usefulness of CHr and the screening performance of %HYPO in predicting IDA among CKD patients are high. Their lower cost compared to conventional markers of ID recommend their use in clinical practice. Further cost effectiveness studies of these parameters are warranted. PMID- 30281655 TI - TIMP3 and TIMP1 are risk genes for bicuspid aortic valve and aortopathy in Turner syndrome. AB - Turner syndrome is caused by complete or partial loss of the second sex chromosome, occurring in ~1 in 2,000 female births. There is a greatly increased incidence of aortopathy of unknown etiology, including bicuspid aortic valve (BAV), thoracic aortic aneurysms, aortic dissection and rupture. We performed whole exome sequencing on 188 Turner syndrome participants from the National Registry of Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Related Conditions (GenTAC). A gene-based burden test, the optimal sequence kernel association test (SKAT-O), was used to evaluate the data with BAV and aortic dimension z-scores as covariates. Genes on chromosome Xp were analyzed for the potential to contribute to aortopathy when hemizygous. Exome analysis revealed that TIMP3 was associated with indices of aortopathy at exome-wide significance (p = 2.27 x 10-7), which was replicated in a separate cohort. The analysis of Xp genes revealed that TIMP1, which is a functionally redundant paralogue of TIMP3, was hemizygous in >50% of our discovery cohort and that having only one copy of TIMP1 increased the odds of having aortopathy (OR = 9.76, 95% CI = 1.91-178.80, p = 0.029). The combinatorial effect of a single copy of TIMP1 and TIMP3 risk alleles further increased the risk for aortopathy (OR = 12.86, 95% CI = 2.57-99.39, p = 0.004). The products of genes encoding tissue inhibitors of matrix metalloproteinases (TIMPs) are involved in development of the aortic valve and protect tissue integrity of the aorta. We propose that the combination of X chromosome TIMP1 hemizygosity and variants of its autosomal paralogue TIMP3, significantly increases the risk of aortopathy in Turner syndrome. PMID- 30281656 TI - Population genetic analysis of autophagy and phagocytosis genes in Drosophila melanogaster and D. simulans. AB - Autophagy and phagocytosis are cellular immune mechanisms for internalization and elimination of intracellular and extracellular pathogens. Some pathogens have evolved the ability to inhibit or manipulate these processes, raising the prospect of adaptive reciprocal co-evolution by the host. We performed population genetic analyses on phagocytosis and autophagy genes in Drosophila melanogaster and D. simulans to test for molecular evolutionary signatures of immune adaptation. We found that phagocytosis and autophagy genes as a whole exhibited an elevated level of haplotype homozygosity in both species. In addition, we detected signatures of recent selection, notably in the Atg14 and Ykt6 genes in D. melanogaster and a pattern of elevated sequence divergence in the genderblind (gb) gene on the D. simulans lineage. These results suggest that the evolution of the host cellular immune system as a whole may be shaped by a dynamic conflict between Drosophila and its pathogens even without pervasive evidence of strong adaptive evolution at the individual gene level. PMID- 30281657 TI - Limited field radiation therapy results in decreased bone fracture toughness in a murine model. AB - Fragility fractures are a well-known complication following oncologic radiotherapy, and it is suspected that radiation-induced embrittlement of bone within the treatment field may contribute to fracture risk. To explore this phenomenon, a mouse model (BALB/cJ) of fractionated, limited field, bilateral hindlimb irradiation (4x5 Gy) was used. The effects of radiation on femoral (cortical) bone fracture toughness, morphology, and biochemistry-including advanced glycation end products (AGEs)-were quantified and compared to Sham group samples prior to irradiation and at 0, 4, 8, and 12 weeks post-irradiation. Additionally, alterations to bone fracture toughness mediated directly by radiation (independent of cellular mechanisms) were determined using devitalized mouse cadaver femurs. Finally, the contribution of AGEs to reduced fracture toughness was examined by artificially ribosylating mouse femurs ex vivo. These data demonstrate that in vivo irradiation results in an immediate (-42% at 0 weeks, p < 0.001) and sustained (-28% at 12 weeks, p < 0.001) decrease in fracture toughness with small changes in morphology (-5% in cortical area at 12 weeks), and minimal changes in bone composition (tissue mineral density, mineral:matrix ratio, and AGE content). Irradiation of devitalized femurs also reduced fracture toughness (-29%, p < 0.001), but to a lesser extent than was seen in vivo. While artificial ribosylation decreased fracture toughness with time, the extent of glycation needed to induce this effect exceeded the AGE accumulation that occurred in vivo. Overall, hindlimb irradiation induced a substantial and sustained decrease in bone fracture toughness. Approximately half of this decrease in fracture toughness is due to direct radiation damage, independent of cellular remodeling. Collagen glycation in vivo was not substantially altered, suggesting other matrix changes may contribute to post radiotherapy bone embrittlement. PMID- 30281658 TI - Long-term results of posterior cruciate ligament tear with or without reconstruction: A nationwide, population-based cohort study. AB - BACKGROUND: There is increasing interest in the long-term outcomes of patients with posterior cruciate ligament (PCL) tears following conservative treatment or reconstruction. However, limited information is available regarding these results because of the relative rarity of cases and lack of long-term follow-up. PURPOSE: The goals of this study are to (1) compare the occurrence of secondary meniscal tears, osteoarthritis (OA) or subsequent total knee replacement (TKR) in patients with or without PCL injury, and (2) evaluate the potential protective effect of PCL reconstruction against long-term sequela in patients with PCL deficiency. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: This retrospective cohort study evaluated the long-term results of PCL deficiency with or without reconstruction in Taiwan based on data from the National Health Insurance Research Database (NHIRD) from 2000 to 2015. The cumulative incidence rates of meniscus tear, OA and TKR were analyzed using the Kaplan-Meier estimator. Cox proportional hazards models were applied to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: A total of 4,169 patients diagnosed with PCL tear from 2000 to 2015 in Taiwan were included in the study. There was a higher cumulative incidence of meniscus tear (1.13%), OA (2.71%) and subsequent TKR (0.91%) among patients with a PCL tear than among patients without one (0.22%, 1.90%, 0.62%; all p < 0.05). PCL reconstruction patients had a decreased cumulative incidence of meniscus tear (0.41%), OA (2.30%) and subsequent TKR (0.48%) compared with non-reconstructed patients (2.44%, 3.46%, 1.69%; all p < 0.05). After adjusting for covariates, PCL-injured patients who underwent reconstruction within one year after PCL injury showed a significantly lower risk of subsequent sequelae than those who never underwent reconstruction (within 1 month: adjusted HR = 0.390, 95% CI = 0.284-0.535; 1 month to 1 year: adjusted HR = 0.546, 95% CI = 0.398-0.748). CONCLUSIONS: Patients with PCL tears have a significantly higher risk of meniscus tear, OA and subsequent TKR than patients without PCL tears. PCL reconstruction could decrease the cumulative incidence of these outcomes. The results suggest that PCL-injured patients should undergo reconstruction as early as possible (within one year) to reduce the risk of further degeneration.

AB - To examine trends in the prevalence of wasting, stunting, overweight, and obesity among children in Luoding, a lower-middle-income city in southern China, we collected height, weight and other information on 65,908 pre-school children aged 2 to 7 years from 23 kindergartens, in which health examinations were conducted annually between 2004 and 2013. We used the growth standards of the World Health Organization (WHO) to calculate Z-scores for height and body mass index (BMI), and used the cut-offs recommended by WHO to define wasting, stunting, overweight, and obesity for each child. From 2004 to 2013, the prevalence of overweight increased from 3.70% to 7.27% and of obesity increased from 1.04% to 2.08%. Meanwhile, the prevalence of wasting decreased from 0.91% to 0.72% and of stunting decreased from 9.29% to 5.22%. These trends suggest there was still a double burden of nutritional status there. The nutritional interventions focusing on pre-school children should be comprehensively elaborated in lower-middle income areas such as Luoding.

AB - With the development of large-scale knowledge bases (KBs), knowledge-based question answering (KBQA) has become an important research topic in recent years. The key task in KBQA is relation detection, which is the process of finding a compatible answer type for a natural language question and generating its corresponding structured query over a KB. However, existing systems often rely on shallow probabilistic methods, which are less expressive than deep semantic representation methods. In addition, since KBs are still far from complete, it is necessary to develop a new strategy that leverages unstructured resources outside of KBs. In this work, we propose a novel Question Answering method with Relation Detection and Textual Evidence (QARDTE). First, to address the semantic gap problem in relation detection, we use bidirectional long-short term memory networks with different levels of abstraction to better capture sentence structures. Our model achieves improved results with robustness against a wide diversity of expressions and questions with multiple relations. Moreover, to help compensate for the incompleteness of KBs, we utilize external unstructured text to extract additional supporting evidence and combine this evidence with relation information during the answer re-ranking process. In experiments on two well known benchmarks, our system achieves F1 values of 0.558 (+2.8%) and 0.663 (+5.7%), which are state-of-the-art results that show significant improvement over existing KBQA systems. PMID- 30281660 TI - Magnitude and risk factors for hypertension among public servants in Tigray, Ethiopia: A cross-sectional study. AB - BACKGROUND: Hypertension is a globally recognized threat to social and economic development with premature morbidity and mortality. In middle and low-income countries hypertension appears to be increasing. However, sufficient data on this silent-killer is not available in Ethiopia. Therefore, this study examined the magnitude and risk factors for hypertension among public servants in Tigray, Ethiopia. METHODS: We used a cross-sectional survey from May-June 2016 among 1525 public servants in Tigray region. Field workers collected data using a pre tested, standardized questionnaire. A multivariate logistic regression analysis conducted to identify risk factors for hypertension. Statistical significance was declared using a p-value<0.05 and 95% of confidence interval (CI) for an adjusted odds ratio (AOR). RESULTS: The overall prevalence of hypertension was 16% (95% CI: 13.10-21.9) and the proportion of awareness (96.7%), treatment (31.3%) and control of hypertension (40.1%) among employees. Being male [AOR = 2.06, 95%CI:1.49, 2.84], ages groups of 30-49 years [AOR = 2.21, 95%CI:1.25, 3.89] and >50years [AOR = 3.61, 95% CI:1.93, 6.69], Body Mass Index(BMI); underweight [AOR = 0.40, 95% CI; 0.20, 0.78], overweight [AOR = 1.70, 95%CI; 1.22, 2.33] and obesity [AOR = 3.20, 95% CI; 1.78, 5.78] were determinants for hypertension. CONCLUSION: The prevalence of hypertension is relatively high in Mekelle city compared with previous reports. This study revealed that male sex, age-group, and BMI were evidenced as risk factors for hypertension. Policy makers need to consider sector wise integrating prevention and control of hypertension. Skilled based information, education and communication strategies should be designed and implemented to avoid unhealthy lifestyles, investing in workforces to eliminate the modifiable risk factors for non-communicable diseases and promote healthy practices. PMID- 30281662 TI - Broad range flavonoid profiling by LC/MS of soybean genotypes contrasting for resistance to Anticarsia gemmatalis (Lepidoptera: Noctuidae). AB - Attack by herbivores is a major biotic stress limiting the soybean crop production. Plant defenses against caterpillars include the production of secondary metabolites such as flavonoids, which constitute a diverse group of plant secondary metabolites. Thus, a more discriminate metabolic profiling between genotypes are important for a more comprehensive and reliable characterization of soybean resistance. Therefore, in this study a non-targeted LC/MS-based for analysis of flavonoid profiles of soybean genotypes contrasting to the resistance to A. gemmatalis was applied. Clustering analysis revealed profiles highly distinct between the susceptible UFV 105 AP and the resistant IAC 17 genotypes. This comparative approach enables to identify directly from leaf extract some new compounds related to resistance, some of which were present in higher abundance specifically in the IAC 17 genotype: four Quercetin conjugates, Rutin (Quercetin 3-O-Rutinoside), Quercetin-3,7-O- di-glucoside, Quercetin-3-O rhamnosylglycoside-7-O-glucoside and Quercetin-3-O-rhamnopyranosyl glucopyranoside-rhamnopyranoside; two Genistein conjugates, Genistein-7-O diglucoside-dimalonylated and Genistein-7-O-6-O-malonylglucoside; and one Daidzein conjugate, Daidzein-7-O-Glucoside-malonate. The most abundant flavonoid glycoconjugates in soybean leaves belongs to Quercetin and Kaempferol classes. However, only one from the identified compounds was classified as a Kaempferol. The Kaempferol-3-O-L-rhamnopyranosyl-glucopyranoside showed high abundance in the resistant genotype IAC 17. The metabolic profiles generated by LC/MS allowed the reconstruction of the flavonoid biosynthetic pathways, which revealed a constitutive character for herbivory resistance in the resistant genotype IAC-17 and a metabolic regulation for the rechanneling of Quercetin, Kaempferol and Genistein conjugates in soybean. Highest relative abundances were detected for glyconjugates, such as Rutin, Quercetin 3-O-rhamnosylglycoside-7-O-glucoside and Quercitin-3-O-rhamnopyranosyl-glucopyranoside-rhamnopyranoside in the leaves of the resistant genotype. PMID- 30281663 TI - Familial risks of ovarian cancer by age at diagnosis, proband type and histology. AB - Ovarian cancer is a heterogeneous disease. Data regarding familial risks for specific proband, age at diagnosis and histology are limited. Such data can assist genetic counseling and help elucidate etiologic differences among various histologic types of ovarian malignancies. By using the Swedish Family-Cancer Database, we calculated relative risks (RRs) for detailed family histories using a two-way comparison, which implied e.g. estimation of RRs for overall ovarian cancer when family history was histology-specific ovarian cancer, and conversely, RRs for histology-specific ovarian cancer when family history was overall ovarian cancer. In families of only mother, only sisters or both mother and sisters diagnosed with ovarian cancer, cancer risks for ovary were 2.40, 2.59 and 10.40, respectively; and were higher for cases diagnosed before the age of 50 years. All histological types showed a familial risk in two-way analyses, except mucinous and sex cord-stromal tumors. RRs for concordant histology were found for serous (2.47), endometrioid (3.59) and mucinous ovarian cancers (6.91). Concordant familial risks were highest for mucinous cancer; for others, some discordant associations, such as endometrioid-undifferentiated (9.27) and serous undifferentiated (4.80), showed the highest RRs. Familial risks are high for early-onset patients and for those with multiple affected relatives. Sharing of different histological types of ovarian cancer is likely an indication of the complexity of the underlying mechanisms. PMID- 30281665 TI - Genetic variation in a colonization specialist, Simulium ruficorne (Diptera: Simuliidae), the world's most widely distributed black fly. AB - The ability of aquatic insects to colonize Earth's most remote freshwater habitats, such as those of islands and deserts, is limited to select taxa. Among black flies, the premiere colonization specialist is Simulium ruficorne Macquart, the only species known from both the Afrotropical and Palearctic regions. We investigated the cytogenetics of S. ruficorne to gain insight into its wide geographic distribution and ability to colonize oceanic islands and deserts. On the basis of larval polytene chromosomes from 14 locations, we documented 17 novel and previously known chromosomal rearrangements and established five cytoforms (A1, A2, B, C, and D), of which probably four (A1/A2, B, C, and D) are distinct species and two (A1 and A2) represent sex-chromosome polymorphism involving a heteroband in the long arm of chromosome III. The chromosome restructuring phenomena associated with the five cytoforms are consistent with the trend in the Simuliidae that one and the same rearrangement can assume different functions in the various descendants of a common ancestor in which the rearrangement was polymorphic. The most widely distributed cytoforms are A1 and A2, which are found in North Africa, the Canary Islands, and Majorca. Simulium ruficorne, the only known black fly in the Hoggar Mountains of the central Sahara Desert, represents a cohesive population of cytoform A1 little differentiated from other North African populations of A1 and A2. Cytoform B inhabits the West African mainland, cytoform C is on Tenerife, and cytoform D is on Cape Verde. We suggest that dispersal and colonization specialists, such as S. ruficorne, are multivoltine inhabitants of temporary streams, and must relocate as their habitats deteriorate. Simulium ruficorne, therefore, should have adaptations that contribute to successful dispersal and colonization, perhaps largely physiological in nature, such as tolerance of high temperatures and droughts. PMID- 30281664 TI - Structural characterization of four different naturally occurring porcine collagen membranes suitable for medical applications. AB - Collagen is the main structural element of connective tissues, and its favorable properties make it an ideal biomaterial for regenerative medicine. In dental medicine, collagen barrier membranes fabricated from naturally occurring tissues are used for guided bone regeneration. Since the morphological characteristics of collagen membranes play a crucial role in their mechanical properties and affect the cellular behavior at the defect site, in-depth knowledge of the structure is key. As a base for the development of novel collagen membranes, an extensive morphological analysis of four porcine membranes, including centrum tendineum, pericardium, plica venae cavae and small intestinal submucosa, was performed. Native membranes were analyzed in terms of their thickness. Second harmonic generation and two-photon excitation microscopy of the native membranes showed the 3D architecture of the collagen and elastic fibers, as well as a volumetric index of these two membrane components. The surface morphology, fiber arrangement, collagen fibril diameter and D-periodicity of decellularized membranes were investigated by scanning electron microscopy. All the membrane types showed significant differences in thickness. In general, undulating collagen fibers were arranged in stacked layers, which were parallel to the membrane surface. Multiphoton microscopy revealed a conspicuous superficial elastic fiber network, while the elastin content in deeper layers varied. The elastin/collagen volumetric index was very similar in the investigated membranes and indicated that the collagen content was clearly higher than the elastin content. The surface of both the pericardium and plica venae cavae and the cranial surface of the centrum tendineum revealed a smooth, tightly arranged and crumpled morphology. On the caudal face of the centrum tendineum, a compact collagen arrangement was interrupted by clusters of circular discontinuities. In contrast, both surfaces of the small intestinal submucosa were fibrous, fuzzy and irregular. All the membranes consisted of largely uniform fibrils displaying the characteristic D-banding. This study reveals similarities and relevant differences among the investigated porcine membranes, suggesting that each membrane represents a unique biomaterial suitable for specific applications. PMID- 30281667 TI - Weather field reconstruction using aircraft surveillance data and a novel meteo particle model. AB - Wind and temperature data are important parameters in aircraft performance studies. The lack of accurate measurements of these parameters forces researchers to rely on numerical weather prediction models, which are often filtered for a larger area with decreased local accuracy. Aircraft, however, also transmit information related to weather conditions, in response to interrogation by air traffic controller surveillance radars. Although not intended for this purpose, aircraft surveillance data contains information that can be used for weather models. This paper presents a method that can be used to reconstruct a weather field from surveillance data that can be received with a simple 1090 MHz receiver. Throughout the paper, we answer two main research questions: how to accurately infer wind and temperature from aircraft surveillance data, and how to reconstruct a real-time weather grid efficiently. We consider aircraft as moving sensors that measure wind and temperature conditions indirectly at different locations and flight levels. To address the first question, aircraft barometric altitude, ground velocity, and airspeed are decoded from down-linked surveillance data. Then, temperature and wind observations are computed based on aeronautical speed conversion equations. To address the second question, we propose a novel Meteo-Particle (MP) model for constructing the wind and temperature fields. Short term local prediction is also possible by employing a predictor layer. Using an unseen observation test dataset, we are able to validate that the mean absolute errors of inferred wind and temperature using MP model are 67% and 26% less than using the interpolated model based on GFS reanalysis data. PMID- 30281666 TI - The assessment of successful emotion regulation skills use: Development and validation of an English version of the Emotion Regulation Skills Questionnaire. AB - Emotion regulation has become an important topic in mental health and psychotherapy research. Skills supposingly relevant for adaptive responses towards emotions include the abilities to be consciously aware of emotions, identify and correctly label emotions, understand what has caused and maintains one's present emotions, modify the intensity or duration of one's emotions, accept and tolerate undesired emotions, confront situations likely to cue negative emotions, and provide effective self-support when working to cope with challenging emotions. To economically assess these abilities, a self-report measure has been developed in German and validated in various studies. To facilitate the use of the measure in English speaking countries, we have developed and validated an English version of the Emotion Regulation Skills Questionnaire (ERSQ) in a student sample (n = 263) and a sample of individual clinical sample (n = 35). Findings from this study provide significant evidence for the reliability and validity of the ERSQ. Thus, the measure can be used to assess a broad range of important emotion regulation skills in an economic way. PMID- 30281668 TI - Country-specific costs of implementing the WHO FCTC tobacco control policies and potential financing sources. AB - BACKGROUND: One of the major obstacles to the full implementation of the World Health Organization (WHO) Framework Convention of Tobacco Control (FCTC) tobacco control measures is the lack of sustainable financing resources. GOAL: To update and simulate country-specific indicators that are highly relevant to the costs and financial resources of the treaty policy implementation. We also developed an Excel tool for simulation and assessed the aggregated-level indicators by the 2016 World Bank income groups. APPROACHES: Using mostly 2016 data or 2014-15 data if 2016 one are not available, we updated five indicators relevant to the treaty implementation, which are the gap between current and desirable policy implementation, cigarette affordability, the costs of implementing best- buy tobacco control policies, the number of smoking-attributable deaths, and the simulated tax revenue resulting from a $1 tax increase. We also aggregated indicators and simulation results by the World Bank income groups, encompassing the five indicators and the reduction in smoking and in attributable deaths due to a hypothetical 1I$ tax increase. Finally, the policy implementation cost was compared with tax revenue and revenue increases. FINDINGS: As of 2016, smoking remains one of the leading causes of premature deaths worldwide while the implementation of best-buy tobacco control policies was below the recommended levels. Meanwhile, there was room to further increase cigarette taxes and prices, as cigarettes remained affordable in many countries. The total costs of implementing best-buy policies in the next 15 years merely account for 8.3% of the 2016 excise tax revenue, indicating that a small proportion of annual tax revenue could fund the implementation of tobacco control policies recommended by the WHO FCTC. CONCLUSIONS: Increasing taxes could have a multiplier impact on curbing tobacco use through aiding the implementation of the WHO FCTC. PMID- 30281669 TI - Integrin-targeted quantitative optoacoustic imaging with MRI correlation for monitoring a BRAF/MEK inhibitor combination therapy in a murine model of human melanoma. AB - PURPOSE: To investigate alphavbeta3-integrin-targeted optoacoustic imaging and MRI for monitoring a BRAF/MEK inhibitor combination therapy in a murine model of human melanoma. MATERIALS AND METHODS: Human BRAF V600E-positive melanoma xenograft (A375)-bearing Balb/c nude mice (n = 10) were imaged before (day 0) and after (day 7) a BRAF/MEK inhibitor combination therapy (encorafenib, 1.3 mg/kg/d; binimetinib, 0.6 mg/kg/d, n = 5) or placebo (n = 5), respectively. Optoacoustic imaging was performed on a preclinical system unenhanced and 5 h after i. v. injection of an alphavbeta3-integrin-targeted fluorescent probe. The alphavbeta3 integrin-specific tumor signal was derived by spectral unmixing. For morphology based tumor response assessments, T2w MRI data sets were acquired on a clinical 3 Tesla scanner. The imaging results were validated by multiparametric immunohistochemistry (beta3 -integrin expression, CD31 -microvascular density, Ki 67 -proliferation). RESULTS: The alphavbeta3-integrin-specific tumor signal was significantly reduced under therapy, showing a unidirectional decline in all animals (from 7.98+/-2.22 to 1.67+/-1.30; p = 0.043). No significant signal change was observed in the control group (from 6.60+/-6.51 to 3.67+/-1.93; p = 0.500). Immunohistochemistry revealed a significantly lower integrin expression (beta3: 0.20+/-0.02 vs. 0.39+/-0.05; p = 0.008) and microvascular density (CD31: 119+/-15 vs. 292+/-49; p = 0.008) in the therapy group. Tumor volumes increased with no significant intergroup difference (therapy: +107+/-42 mm3; control +112+/ 44mm3, p = 0.841). In vivo blocking studies with alphavbeta3-integrin antagonist cilengitide confirmed the target specificity of the fluorescent probe. CONCLUSIONS: alphavbeta3-integrin-targeted optoacoustic imaging allowed for the early non-invasive monitoring of a BRAF/MEK inhibitor combination therapy in a murine model of human melanoma, adding molecular information on tumor receptor status to morphology-based tumor response criteria. PMID- 30281670 TI - The eNOS-NO pathway attenuates kidney dysfunction via suppression of inflammasome activation in aldosterone-induced renal injury model mice. AB - Hypertension causes vascular complications, such as stroke, cardiovascular disease, and chronic kidney disease (CKD). The relationship between endothelial dysfunction and progression of kidney disease is well known. However, the relationship between the eNOS-NO pathway and chronic inflammation, which is a common pathway for the progression of kidney disease, remains unexplored. We performed in vivo experiments to determine the role of the eNOS-NO pathway by using eNOS-deficient mice in a hypertensive kidney disease model. All mice were unilateral nephrectomized (Nx). One week after Nx, the mice were randomly divided into two groups: the aldosterone infusion groups and the vehicle groups. All mice also received a 1% NaCl solution instead of drinking water. The aldosterone infusion groups were treated with hydralazine to correct blood pressure differences. After four weeks of drug administration, all mice were euthanized, and blood and kidney tissue samples were collected. In the results, NLRP3 inflammasome activation was elevated in the kidneys of the eNOS-deficient mice, and tubulointerstitial fibrosis was accelerated. Suppression of inflammasome activation by knocking out ASC prevented tubulointerstitial injury in the eNOS knockout mice, indicating that the eNOS-NO pathway is involved in the development of kidney dysfunction through acceleration of NLRP3 inflammasome in macrophages. We revealed that endothelial function, particularly the eNOS-NO pathway, attenuates the progression of renal tubulointerstitial injury via suppression of inflammasome activation. Clinically, patients who develop vascular endothelial dysfunction have lifestyle diseases, such as hypertension or diabetes, and are known to be at risk for CKD. Our study suggests that the eNOS-NO pathway could be a therapeutic target for the treatment of chronic kidney disease associated with endothelial dysfunction. PMID- 30281671 TI - Scientific evidence underlying the American College of Gastroenterology's clinical practice guidelines. AB - BACKGROUND: Clinical practice guidelines contain recommendations for physicians to determine the most appropriate care for patients. These guidelines systematically combine scientific evidence and clinical judgment, culminating in recommendations intended to optimize patient care. The recommendations in CPGs are supported by evidence which varies in quality. We aim to survey the clinical practice guidelines created by the American College of Gastroenterology, report the level of evidence supporting their recommendations, and identify areas where evidence can be improved with additional research. METHODS: We extracted 1328 recommendations from 39 clinical practice guidelines published by the American College of Gastroenterology. Several of the clinical practice guidelines used the differing classifications of evidence for their recommendations. To standardize our results, we devised a uniform system for evidence. RESULTS: A total of 39 clinical practice guidelines were surveyed in our study. Together they account for 1328 recommendations. 693 (52.2%) of the recommendations were based on low evidence, indicating poor evidence or expert opinion. Among individual guidelines, 13/39 (33.3%) had no recommendations based on high evidence. CONCLUSION: Very few recommendations made by the American College of Gastroenterology are supported by high levels of evidence. More than half of all recommendations made by the American College of Gastroenterology are based on low quality evidence or expert opinion. PMID- 30281672 TI - Positive perception of aging is a key predictor of quality-of-life in aging people. AB - OBJECTIVE: We conducted a cross-sectional survey in France in a cohort over 55 years of age to characterize the impact of psychological dimensions on quality-of life (QoL). METHODS: The predictors of QoL in relation with aging were studied using an adapted quality-of-life model, based on emotional, cognitive and physical symptoms, functional status, and general health perception. Adding psychological dimensions such as self-esteem, psychological distress, perceptions of ageing and coping, was hypothesized to improve the QoL model. Responses were analyzed using structural equation modeling and path analysis. RESULTS: The study involved 258 participants, mean age 66.9+/-7.9 years. Psychological distress and positive perception of aging exhibited the strongest direct impact on QoL (p<0.0001). Psychological distress also appeared to be mediator on QoL for perceived health status, self-esteem and negative perception of aging. Coping centred on emotion exhibited direct impact on self-esteem and so, indirect impact on QoL (p = 0.0002). Perception of personal financial situation (p = 0.0007) and coping centred on social support (p = 0.02) appeared as direct mediators influencing QoL. CONCLUSIONS: Psychological dimensions are predictors of QOL and have to be taken into account to maximize the resources with a view to successful aging. Further interventions targeting successful aging should focus on positive perception aging. PMID- 30281673 TI - Structure and development of flowers and inflorescences in Peraceae and Euphorbiaceae and the evolution of pseudanthia in Malpighiales. AB - Pseudanthia are reduced and compact inflorescences which apparently had independent evolution in Euphorbiaceae and Peraceae within Malpighiales. In order to analyze the hypothesis that the different pseudanthia found in Malpighiales have non-homologous developmental steps, we studied the inflorescence and flower development in the three Malpighiales genera that present this type of inflorescence-Dalechampia (Acalyphoideae/Euphorbiaceae), Euphorbia (Euphorbioideae/Euphorbiaceae), and Pera (Peraceae)-and compared them to that of Joannesia (Crotonoideae/Euphorbiaceae), which does not present a pseudanthium. Inflorescences and flowers were analyzed using light microscopy and scanning electron microscopy. Dalechampia and Euphorbia have protogynic bisexual pseudanthia, with unisexual perianthed flowers in Dalechampia, and achlamydeous flowers in Euphorbia. Pera has unisexual pseudanthia and the male flowers have a vestigial calyx and the female flowers are achlamydeous. Joannesia flowers are very distinct when compared to the pseudanthia flowers, as they are composed of all the whorls and there is no reduction. In the early stages of development, the first structures to be formed in the pseudanthia are the different series of bracts, including outer, involucral and involucel bracts. The floral primordia are initiated almost simultaneously with the involucre. Although the different morphology, the early inflorescence followed the same branching pattern in all studied genera, and the number and elongation of the branches were affected by the early female flower development in the terminal position. We suggest that the different pseudanthia evolved via process of floral whorl reduction and reorganization of flowers in the inflorescence axes, especially the position of female and male flowers and elongation or shortening of the branches. The sex of the terminal flower is a developmental key, i.e., the protogynic development deeply affects the pseudanthia growth, reducing the ramification and elongation of the axes. PMID- 30281675 TI - Linking root exudates to functional plant traits. AB - Primary and secondary metabolites exuded by plant roots have mainly been studied under laboratory conditions, while knowledge of root exudate patterns of plants growing in natural communities is very limited. Focusing on ten common European grassland plant species, we asked to which degree exuded metabolite compositions are specific to species or growth forms (forbs and grasses), depend on environments and local neighbourhoods, and reflect traditional plant functional traits. Root exudates were collected under field conditions and analysed using a non-targeted gas chromatography coupled mass spectrometry (GC-MS) approach. In total, we annotated 153 compounds of which 36 were identified by structure and name as metabolites mainly derived from the primary metabolism. Here we show by using variance partitioning, that the composition of exuded polar metabolites was mostly explained by plot identity, followed by plant species identity while plant species composition of the local neighbourhood played no role. Total and root dry biomass explained the largest proportion of variance in exudate composition, with additional variance explained by traditional plant traits. Although the exudate composition was quite similar between the two growth forms, we found some metabolites that occurred only in one of the two growth forms. Our study demonstrated the feasibility of measuring polar exudates under non-sterile field conditions by mass spectrometry, which opens new avenues of research for functional plant ecology. PMID- 30281674 TI - Rare haplotype load as marker for lethal mutagenesis. AB - RNA viruses replicate with a template-copying fidelity, which lies close to an extinction threshold. Increases of mutation rate by nucleotide analogues can drive viruses towards extinction. This transition is the basis of an antiviral strategy termed lethal mutagenesis. We have introduced a new diversity index, the rare haplotype load (RHL), to describe NS5B (polymerase) mutant spectra of hepatitis C virus (HCV) populations passaged in absence or presence of the mutagenic agents favipiravir or ribavirin. The increase in RHL is more prominent in mutant spectra whose expansions were due to nucleotide analogues than to multiple passages in absence of mutagens. Statistical tests for paired mutagenized versus non-mutagenized samples with 14 diversity indices show that RHL provides consistently the highest standardized effect of mutagenic treatment difference for ribavirin and favipiravir. The results indicate that the enrichment of viral quasispecies in very low frequency minority genomes can serve as a robust marker for lethal mutagenesis. The diagnostic value of RHL from deep sequencing data is relevant to experimental studies on enhanced mutagenesis of viruses, and to pharmacological evaluations of inhibitors suspected to have a mutagenic activity. PMID- 30281676 TI - Rapid capture and detection of ostreid herpesvirus-1 from Pacific oyster Crassostrea gigas and seawater using magnetic beads. AB - Ostreid herpesvirus-1 (OsHV-1) has been involved in mass mortality episodes of Pacific oysters Crassostrea gigas throughout the world, causing important economic losses to the aquaculture industry. In the present study, magnetic beads (MBs) coated with an anionic polymer were used to capture viable OsHV-1 from two types of naturally infected matrix: oyster homogenate and seawater. Adsorption of the virus on the MBs and characterisation of the MB-virus conjugates was demonstrated by real-time quantitative PCR (qPCR). To study the infective capacity of the captured virus, MB-virus conjugates were injected in the adductor muscle of naive spat oysters, using oyster homogenate and seawater without MBs as positive controls, and bare MBs and sterile water as negative controls. Mortalities were induced after injection with MB-virus conjugates and in positive controls, whereas no mortalities were recorded in negative controls. Subsequent OsHV-1 DNA and RNA analysis of the oysters by qPCR and reverse transcription qPCR (RT-qPCR), respectively, confirmed that the virus was the responsible for the mortality event and the ability of the MBs to capture viable viral particles. The capture of viable OsHV-1 using MBs is a rapid and easy isolation method and a promising tool, combined with qPCR, to be applied to OsHV-1 detection in aquaculture facilities. PMID- 30281677 TI - Associations between poverty, mental health and substance use, gender power, and intimate partner violence amongst young (18-30) women and men in urban informal settlements in South Africa: A cross-sectional study and structural equation model. AB - : Research suggests that poverty is a key driver of intimate partner violence (IPV), however detailed analysis suggests that this relationship is not clear, either for women's experience or men's perpetration of IPV. We explored associations between poverty and IPV using cross-sectional data from the Stepping Stones and Creating Futures cluster randomized control trial, in urban informal settlements in Durban, South Africa, with young (18-30) people. Using logistic regression and structural equation modelling we assess associations between poverty and women's experience and men's perpetration of physical and/or sexual IPV in the past 12 months. 680 women and 677 men were recruited into the study between September 2015 and September 2016. The analyses highlight how specific forms or measures of poverty intersecting with gender identities shape IPV. For men we found indicators of economic provision were associated with IPV perpetration, while for women food-insecurity was key to IPV experience. We also found similarities between women and men. First, food-insecurity and childhood traumas shaped pathways to substance misuse and poor mental health that increased IPV. Second, there was a resilience pathway in both models, whereby those with more education had increased gender equitable attitudes and fewer controlling behaviours, which reduced IPV. Interventions to reduce IPV need to work to reduce household food insecurity, but these need to be combined with gender transformative interventions. Interventions should also focus on reducing the impact of mental health and substance misuse. Finally, working to increase educational attainment is a long-term critical intervention to reduce IPV.

AB - The Cancer Genome Atlas (TCGA) provides a genetic characterization of more than ten thousand tumors, enabling the discovery of novel driver mutations, molecular subtypes, and enticing drug targets across many histologies. Here we investigated why some mutations are common in particular cancer types but absent in others. As an example, we observed that the gene CCDC168 has no mutations in the stomach adenocarcinoma (STAD) cohort despite its common presence in other tumor types. Surprisingly, we found that the lack of called mutations was due to a systematic insufficiency in the number of sequencing reads in the STAD and other cohorts, as opposed to differential driver biology. Using strict filtering criteria, we found similar behavior in four other genes across TCGA cohorts, with each gene exhibiting systematic sequencing depth issues affecting the ability to call mutations. We identified the culprit as the choice of exome capture kit, as kit choice was highly associated with the set of genes that have insufficient reads to call a mutation. Overall, we found that thousands of samples across all cohorts are subject to some capture kit problems. For example, for the 6353 samples using the Broad Institute's Custom capture kit there are undercalling biases for at least 4833 genes. False negative mutation calls at these genes may obscure biological similarities between tumor types and other important cancer driver effects in TCGA datasets.

AB - BACKGROUND: Tuberculosis (TB) patients with human immunodeficiency virus (HIV) co infection have worse TB treatment outcomes compared to patients with TB alone. The distribution of unfavourable treatment outcomes differs by socio-demographic and clinical characteristics, allowing for early identification of patients at risk. OBJECTIVE: To develop a statistical model that can provide individual probabilities of unfavourable outcomes based on demographic and clinical characteristics of TB-HIV co-infected patients. METHODOLOGY: We used data from all TB patients with known HIV-positive test results (aged >=15 years) registered for first-line anti-TB treatment (ATT) in 2015 under the Revised National TB Control Programme (RNTCP) in Delhi, India. We included variables on demographics and pre-treatment clinical characteristics routinely recorded and reported to RNTCP and the National AIDS Control Organization. Binomial logistic regression was used to develop a statistical model to estimate probabilities of unfavourable TB treatment outcomes (i.e., death, loss to follow-up, treatment failure, transfer out of program, and a switch to drug-resistant regimen). RESULTS: Of 55,260 TB patients registered for ATT in 2015 in Delhi, 928 (2%) had known HIV positive test results. Of these, 816 (88%) had drug-sensitive TB and were >=15 years. Among 816 TB-HIV patients included, 157 (19%) had unfavourable TB treatment outcomes. We developed a model for predicting unfavourable outcomes using age, sex, disease classification (pulmonary versus extra-pulmonary), TB treatment category (new or previously treated case), sputum smear grade, known HIV status at TB diagnosis, antiretroviral treatment at TB diagnosis, and CD4 cell count at ATT initiation. The chi-square p-value for model calibration assessed using the Hosmer-Lemeshow test was 0.15. The model discrimination, measured as the area under the receiver operator characteristic (ROC) curve, was 0.78. CONCLUSION: The model had good internal validity, but should be validated with an independent cohort of TB-HIV co-infected patients to assess its performance before clinical or programmatic use. PMID- 30281680 TI - Clinical-epidemiological and laboratory profiles of severe Schistosomiasis mansoni infections at a university hospital. AB - OBJECTIVE: Schistosomiasis remains a public health problem. This was a descriptive and retrospective study of 42 patients with a severe form of schistosomiasis who were admitted to the outpatient clinic of the Faculdade de Medicina da Universidade de Sao Paulo, Sao Paulo, in Sao Paulo, Brazil. METHODS: A data collection questionnaire was designed from the patient charts, and the following variables were evaluated: age, sex, place of birth, occupation, signs and symptoms of schistosomiasis, data from laboratory and imaging examinations, data regarding treatment outcomes, and the existence of comorbidities. Statistical analysis was carried out using Statistical Package for the Social Sciences 15.0 and Microsoft Excel 2003 software. The significance levels of the tests were fixed, accepting 5% type 1 error (alpha=0.05). Since this was a retrospective observational study, not all data were available for analysis. RESULTS: The mean age of the patients was 48.24 years; 57.1% were male. Statistically significant associations were observed between splenomegaly and thrombocytopenia (p=0.004) and between splenomegaly and leukopenia (p=0.046); however, only 4.5% of the patients had esophageal hemorrhage. Some patients received a specific treatment; of those, 42% took praziquantel, and 35.4% took oxamniquine. Nonspecific drug therapy was given as follows: 65% received propranolol, 90% omeprazole, and 43.6% aluminum hydroxide. The other treatments were as follows: 92.9% of patients underwent endoscopic treatment, 85% received sclerotherapy, and 62.5% used elastic bandages. CONCLUSION: This preliminary study presents a multidisciplinary outpatient follow-up associated with endoscopic and drug treatments that may be effective at preventing bleeding. PMID- 30281681 TI - Relationship between the biomechanical properties of the cornea and anterior segment measurements. AB - OBJECTIVE: To evaluate the relationship of biomechanical properties, corneal hysteresis and corneal resistance factor with age, sex and various corneal parameters measured with a Pentacam in normal subjects. METHODS: A total of 226 eyes from 113 patients were enrolled in this study. The subjects underwent Ocular Response Analyzer and Pentacam evaluations. A varying-intercept multilevel regression was implemented using Bayesian inference. The predictor variables were age, sex, central corneal thickness, corneal volume at a 7-mm diameter, anterior chamber angle and volume, anterior chamber depth, mean radius of the corneal curvature and corneal astigmatism. RESULTS: Corneal hysteresis ranged from 5.5 to 14.8 mmHg (mean 10.42+/-1.74 mmHg), and the corneal resistance factor ranged from 5.7 to 15.5 mmHg (mean 10.23+/-1.88 mmHg). No predictor variable other than gender and central corneal thickness had a significant correlation with either corneal hysteresis or corneal resistance factor. Corneal hysteresis was positively associated with female sex and with central corneal thickness, and corneal resistance factor was positively associated with central corneal thickness. CONCLUSION: Despite the associations found, only a small fraction of the variance in biomechanical measurements could be explained by the descriptors that were evaluated, indicating the influence of other corneal aspects on the biomechanical characteristics. PMID- 30281682 TI - Using UV light for adhesive remnant removal after debonding of orthodontic accessories. AB - The objective of this study was to assess the effect of a UV light-based auxiliary illumination on adhesive remnant (AR) removal after orthodontic debonding. Sixty human molars were divided according to the adhesive used for bonding: O-opaque; LF-low fluorescence; and HF-high fluorescence. After debonding, the teeth were subdivided according to the AR removal method: No UV light or With UV light. After AR removal, the teeth were polished. Direct visual analysis, scanning electron microscopy (SEM) and time quantification for AR removal analyses were performed (Fisher-Freeman-Halton, Fisher's exact, chi square trend, ANOVA, and independent t-tests; alpha = 5%). Concerning the adhesives, there was no significant difference among direct visual, SEM and time analyses for AR removal (p >= 0.05). Regarding AR removal methods, a similarity among the subgroups was verified for direct visual and SEM analyses (p>=0.05). However, a significant trend was verified for the with UV light method to produce greater marks, and the no UV light method, to produce a greater rate of samples with AR before polishing (p = 0.015). AR removal with light was significantly quicker in comparison with the no UV light method (p < 0.0001). The use of UV light may aid orthodontists in removing AR more thoroughly and in less time. However, they should receive special training to apply this technology, and should never dismiss the final polishing procedure. PMID- 30281683 TI - Systemic melatonin application increases bone formation in mandibular distraction osteogenesis. AB - This study aimed to investigate the effects of different doses of systemic melatonin application on new bone formation during mandibular distraction osteogenesis (DO) in rats. Mandibular DO was performed on 30 adult female Sprague Dawley rats, which were randomly divided into three groups: control group (CNT), melatonin dose 1 (MLT-D1), and melatonin dose 2 (MLT-D2). A five-day latent waiting period and a ten-day distraction phase followed the surgery. After the surgery, rats from the MLT-D1 and MLT-D2 groups received 25 and 50 mg/kg melatonin, respectively, at 7, 14, 21, 28, and 35 days. The animals were euthanised 28 days after distraction, i.e. at 43 days after surgery. Histological and histomorphometric analyses revealed that the distracted bone area was completely filled with new bone formation in all three groups. The MLT-D2 group exhibited the most new bone formation, followed by MLT-D1 and CNT. The melatonin groups had more osteoclasts than the CNT (p < 0.05). The number of osteoblasts was higher in the melatonin groups than in the CNT group, and the MLT-D2 had more osteoclasts than the MLT-D1 group (p < 0.05). Finally, the osteopontin (OPN) and vascular endothelial growth factor (VEGF) levels were higher in the melatonin groups than in the CNT group, and the MLT-D2 had higher OPN and VEGF levels than the MLT-D1 (p < 0.05). This study suggests that systemic melatonin application could increase new bone formation in DO. PMID- 30281684 TI - Factors Associated with Inadequate Management of Antiplatelet Agents in Perioperative Period of Non-Cardiac Surgeries. AB - BACKGROUND: The current guidelines dispose recommendations to manage antiplatelet agents in the perioperative period; however, the daily medical practices lack standardization. OBJECTIVES: To asses factors associated with inadequate management of antiplatelet agents in the perioperative period of non-cardiac surgeries. METHODS: Cross-sectional Study conducted in hospital from October 2014 to October 2016. The study dependent variable was a therapy that did not comply with the recommendations in the Brazilian Association of Cardiology (SBC) guidelines. The independent variables included some characteristics, the people in charge of the management and causes of lack of adherence to those guidelines. Variables were included in the multivariate model. Analysis was based on the odds ratio (OR) value and its respective 95% confidence interval (CI) estimated by means of logistic regression with 5% significance level. RESULTS: The sample was composed of adult patients submitted to non-cardiac surgeries and who would use acetylsalicylic acid (aspirin) or clopidogrel (n = 161). The management failed to comply with the recommendations in the guidelines in 80.75% of the sample. Surgeons had the highest number of noncomplying orientations (n = 63). After multivariate analysis it was observed that patients with a higher level of schooling (OR = 0.24; CI95% 0.07-0.78) and those with a previous episode of acute myocardial infarction (AMI) (OR = 0.18; CI95% 0.04-0.95) had a higher probability of using a therapy complying with the guidelines. CONCLUSION: Positive association between patients' schooling level, or those with a history of previous AMI, with management of the use of aspirin and clopidogrel in the perioperative period of non-cardiac surgeries. However, diverging conducts stress the need of having internal protocol defined. PMID- 30281685 TI - Effects of Rosuvastatin on Apolipoprotein J in Balloon-Injured Carotid Artery in Rats. AB - BACKGROUND: Restenosis after percutaneous coronary intervention in coronary heart disease remains an unsolved problem. Clusterin (CLU) (or Apolipoprotein [Apo] J) levels have been reported to be elevated during the progression of postangioplasty restenosis and atherosclerosis. However, its role in neointimal hyperplasia is still controversial. OBJECTIVE: To elucidate the role Apo J in neointimal hyperplasia in a rat carotid artery model in vivo with or without rosuvastatin administration. METHODS: Male Wistar rats were randomly divided into three groups: the control group (n = 20), the model group (n = 20) and the statin intervention group (n = 32). The rats in the intervention group were given 10mg /kg dose of rosuvastatin. A 2F Fogarty catheter was introduced to induce vascular injury. Neointima formation was analyzed 1, 2, 3 and 4 weeks after balloon injury. The level of Apo J was measured by real-time PCR, immunohistochemistry and western blotting. RESULTS: Intimal/medial area ratio (intimal/medial, I/M) was increased after balloon-injury and reached the maximum value at 4weeks in the model group; I/M was slightly increased at 2 weeks and stopped increasing after rosuvastatin administration. The mRNA and protein levels of Apo J in carotid arteries were significantly upregulated after rosuvastatin administration as compared with the model group, and reached maximum values at 2 weeks, which was earlier than in the model group (3 weeks). CONCLUSION: Apo J served as an acute phase reactant after balloon injury in rat carotid arteries. Rosuvastatin may reduce the neointima formation through up-regulation of Apo J. Our results suggest that Apo J exerts a protective role in the restenosis after balloon injury in rats. PMID- 30281686 TI - Usefulness of preoperative venography in patients with cardiac implantable electronic devices submitted to lead replacement or device upgrade procedures. AB - BACKGROUND: Venous obstructions are common in patients with transvenous cardiac implantable electronic devices, but they rarely cause immediate clinical problems. The main consequence of these lesions is the difficulty in obtaining venous access for additional leads implantation. OBJECTIVES: We aimed to assess the prevalence and predictor factors of venous lesions in patients referred to lead reoperations, and to define the role of preoperative venography in the planning of these procedures. METHODS: From April 2013 to July 2016, contrast venography was performed in 100 patients referred to device upgrade, revision and lead extraction. Venous lesions were classified as non-significant (< 50%), moderate stenosis (51-70%), severe stenosis (71-99%) or occlusion (100%). Collateral circulation was classified as absent, discrete, moderate or accentuated. The surgical strategy was defined according to the result of the preoperative venography. Univariate analysis was used to investigate predictor factors related to the occurrence of these lesions, with 5% of significance level. RESULTS: Moderate venous stenosis was observed in 23%, severe in 13% and occlusions in 11%. There were no significant differences in relation to the device side or the venous segment. The usefulness of the preoperative venography to define the operative tactic was proven, and in 99% of the cases, the established surgical strategy could be performed according to plan. CONCLUSIONS: The prevalence of venous obstruction is high in CIED recipients referred to reoperations. Venography is highly indicated as a preoperative examination for allowing the adequate surgical planning of procedures involving previous transvenous leads. PMID- 30281687 TI - Anger and Coronary Artery Disease in Women Submitted to Coronary Angiography: A 48-Month Follow-Up. AB - BACKGROUND: Anger control was significantly lower in patients with coronary artery disease (CAD), regardless of traditionally known risk factors, occurrence of prior events or other anger aspects in a previous study of our research group. OBJECTIVE: To assess the association between anger and CAD, its clinical course and predictors of low anger control in women submitted to coronary angiography. METHODS: This is a cohort prospective study. Anger was assessed by use of Spielberger's State-Trait Anger Expression Inventory (STAXI). Women were consecutively scheduled to undergo coronary angiography, considering CAD definition as >= 50% stenosis of one epicardial coronary artery. RESULTS: During the study, 255 women were included, being divided into two groups according to their anger control average (26.99). Those with anger control below average were younger and had a family history of CAD. Patients were followed up for 48 months to verify the occurrence of major cardiovascular events. CONCLUSION: Women with CAD undergoing coronary angiography had lower anger control, which was associated with age and CAD family history. On clinical follow-up, event-free survival did not significantly differ between patients with anger control above or below average. PMID- 30281688 TI - Prognostic Differences between Men and Women with Acute Coronary Syndrome. Data from a Brazilian Registry. AB - BACKGROUND: Gender-related differences have been reported in patients with acute coronary syndrome. The description of this comparative finding in a Brazilian registry has not yet been documented. OBJECTIVE: To compare male vs. female patients regarding the baseline characteristics, coronary findings, treatment and in-hospital and long-term prognosis. METHODS: This is a retrospective, multicenter and observational study that included 3,745 patients (2,437 males and 1,308 females) between May 2010 and May 2015. The primary in-hospital outcome was all-cause mortality. The secondary outcome consisted of combined events (cardiogenic shock, reinfarction, death, stroke and bleeding). The comparison between groups was performed using the chi-square and the t test, considering p < 0.05 as significant. In the long term, mortality and combined events were assessed using the Kaplan-Meier method, with a mean follow-up of 8.79 months. RESULTS: The mean age was 60.3 years for males and 64.6 for females (p < 0.0001). The most prevalent risk factor was systemic arterial hypertension in 72.9% of the women and 67.8% of the men (p = 0.001). Percutaneous coronary intervention was carried out in 44.9% of the males and 35.4% of the females (p < 0.0001), and coronary artery bypass grafting (CABG) was performed in 17% of the males and 11.8% of females (p < 0.0001), with a higher prevalence of three-vessel coronary artery disease in males (27.3% vs. 16.2%, p < 0.0001). Approximately 79.9% of the female patients received a diagnosis of acute coronary syndrome without ST segment elevation, while in the male patients, this diagnosis was attained in 71.5% (p < 0.0001). No significant differences were observed between the groups in the short and long term, regarding both mortality and the combined events. CONCLUSION: Several gender-related differences were observed in patients with acute coronary syndrome regarding the demographic characteristics, coronary artery disease pattern and implemented treatment. However, the prognostic evolution was similar between the groups. PMID- 30281689 TI - Comparison of Cardiac and Vascular Parameters in Powerlifters and Long-Distance Runners: Comparative Cross-Sectional Study. AB - BACKGROUND: Cardiac remodeling is a specific response to exercise training and time exposure. We hypothesized that athletes engaging for long periods in high intensity strength training show heart and/or vascular damage. OBJECTIVE: To compare cardiac characteristics (structure and function) and vascular function (flow-mediated dilation [FMD] and peripheral vascular resistance [PVR]) in powerlifters and long-distance runners. METHODS: We evaluated 40 high-performance athletes (powerlifters [PG], n = 16; runners [RG], n = 24) and assessed heart structure and function (echocardiography), systolic and diastolic blood pressure (SBP/DBP), FMD, PVR, maximum force (squat, bench press, and deadlift), and maximal oxygen uptake (spirometry). A Student's t Test for independent samples and Pearson's linear correlation were used (p < 0.05). RESULTS: PG showed higher SBP/DBP (p < 0.001); greater interventricular septum thickness (p < 0.001), posterior wall thickness (p < 0.001) and LV mass (p < 0.001). After adjusting LV mass by body surface area (BSA), no difference was observed. As for diastolic function, LV diastolic volume, wave E, wave e', and E/e' ratio were similar for both groups. However, LA volume (p = 0.016) and BSA-adjusted LA volume were lower in PG (p < 0.001). Systolic function (end-systolic volume and ejection fraction), and FMD were similar in both groups. However, higher PVR in PG was observed (p = 0.014). We found a correlation between the main cardiovascular changes and total weight lifted in PG. CONCLUSIONS: Cardiovascular adaptations are dependent on training modality and the borderline structural cardiac changes are not accompanied by impaired function in powerlifters. However, a mild increase in blood pressure seems to be related to PVR rather than endothelial function. PMID- 30281690 TI - Arterial Stiffness Use for Early Monitoring of Cardiovascular Adverse Events due to Anthracycline Chemotherapy in Breast Cancer Patients. A Pilot Study. AB - BACKGROUND: Chemotherapy with doxorubicin and cyclophosphamide, although efficient for treating breast cancer, is associated with cardiovascular complications. Recent studies seek to identify methods that can early detect cardiological and vascular changes as a strategy to decrease the incidence of cardiovascular comorbidities. OBJECTIVE: To evaluate the role of arterial stiffness measurement in the monitoring of doxorubicin and cyclophosphamide induced cardiotoxicity in breast cancer patients. METHODS: Prospective longitudinal study in 24 breast cancer patients undergoing treatment with doxorubicin and cyclophosphamide. Patients underwent an indirect evaluation of arterial stiffness through non-invasive measurement of hemodynamic parameters such as pulse wave velocity with the Mobil-O-Graph(r) 24H PWA device at three different times of the chemotherapy treatment (pre-chemotherapy, after the first and the fourth cycle). The left ventricular ejection fraction was also evaluated by Doppler echocardiography (pre-chemotherapy and after the fourth chemotherapy cycle). Data were considered significant when p <= 0.05. RESULTS: Patients had a mean age of 52.33 +/- 8.85 years and body mass index of 31 +/- 5.87 kg/m2. There was no significant difference between the hemodynamic parameters evaluated by the oscillometric method or in the left ventricular ejection fraction in the different evaluated periods. CONCLUSION: Evaluations of arterial stiffness by oscillometry and measurement of left ventricular ejection fraction by Doppler echocardiography showed equivalence in the values found, suggesting that the evaluation method of arterial stiffness studied could be used as a marker for cardiovascular adverse events associated with doxorrubicin-based chemotherapy drugs. PMID- 30281691 TI - Validation of the Brazilian-Portuguese Version of a Short Questionnaire to Assess Knowledge in Cardiovascular Disease Patients (CADE-Q SV). AB - BACKGROUND: Patient education is an essential part of cardiovascular patients' care targeting self-management behavior to reduce risk factors and subsequent events. Herein, a short and reliable tool to assess patients' knowledge in Brazil is warranted. OBJECTIVES: To translate, culturally-adapt and psychometrically validate the Portuguese version of the Coronary Artery Disease Education Questionnaire Short Version (CADE-Q SV). METHODS: The Portuguese CADE-Q SV - translated and culturally-adapted - was reviewed by five bilingual experts in cardiovascular disease. This version was then pre-tested in 21 patients, and clarity of items was checked using a Likert-type scale ranging from 1 = not clear to 10 = very clear. It was then psychometrically tested in 200 cardiovascular patients (41%women; mean age = 58.4 +/- 11.6 years old). The internal consistency was assessed using Kuder-Richardson-20 (KR-20) and Cronbach's alpha, test-retest reliability through intraclass correlation coefficient (ICC), factor structure using confirmatory factor analysis, and construct validity regarding educational level, family income, and time of diagnosis. RESULTS: All questions were considered clear by patients (clarity range:7.8-9.6). KR-20 was 0.70. All ICC values were > 0.70. Factor analysis revealed 6 factors, all internally consistent. Construct validity was supported by significant differences in total scores by educational level and family income (p < 0.001). The overall mean was 13.08 +/- 2.61. The area with the highest knowledge was risk factors and the lowest was psychosocial risk. CONCLUSIONS: The Portuguese CADE-SV was demonstrated to have good validity and reliability. This tool can be applicable in clinical and research settings, assessing cardiovascular patients' knowledge as part of an education programming. PMID- 30281692 TI - Fractional Flow Reserve-Guided Strategy in Acute Coronary Syndrome. A Systematic Review and Meta-Analysis. AB - BACKGROUND: There are limited data on the prognosis of deferral of lesion treatment in patients with acute coronary syndrome (ACS) based on fractional flow reserve (FFR). OBJECTIVES: To provide a systematic review of the current evidence on the prognosis of deferred lesions in ACS patients compared with deferred lesions in non-ACS patients, on the basis of FFR. METHODS: We searched Medline, EMBASE, and the Cochrane Library for studies published between January 2000 and September 2017 that compared prognosis of deferred revascularization of lesions on the basis of FFR in ACS patients compared with non-ACS patients. We conducted a pooled relative risk meta-analysis of four primary outcomes: mortality, cardiovascular (CV) mortality, myocardial infarction (MI) and target-vessel revascularization (TVR). RESULTS: We identified 7 studies that included a total of 5,107 patients. A pooled meta-analysis showed no significant difference in mortality (relative risk [RR] = 1.44; 95% CI, 0.9-2.4), CV mortality (RR = 1.29; 95% CI = 0.4-4.3) and TVR (RR = 1.46; 95% CI = 0.9-2.3) after deferral of revascularization based on FFR between ACS and non-ACS patients. Such deferral was associated with significant additional risk of MI (RR = 1.83; 95% CI = 1.4 2.4) in ACS patients. CONCLUSION: The prognostic value of FFR in ACS setting is not as good as in stable patients. The results demonstrate an increased risk of MI but not of mortality, CV mortality, and TVR in ACS patients. PMID- 30281693 TI - Association Between Increased Levels of Cystatin C and the Development of Cardiovascular Events or Mortality: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Cystatin C seems promising for evaluating the risk of cardiovascular events and mortality. OBJECTIVE: To evaluate the association between high levels of cystatin C and the development of cardiovascular events or mortality. METHODS: The articles were selected in the Medline/PubMed, Web of Science, and Scielo databases. The eligibility criteria were prospective cohort observational trials that assessed the association of high serum levels of cystatin C with the development of cardiovascular events or mortality in individuals with normal renal function. Only studies that evaluated the mortality outcome compared the fourth with the first quartile of cystatin C and performed multivariate Cox's proportional hazard regression analysis were included in the meta-analysis. A p value < 0,05 was considered significant. RESULTS: Among the 647 articles found, 12 were included in the systematic review and two in the meta-analysis. The risk of development of adverse outcomes was assessed by eight studies using the hazard ratio. Among them, six studies found an increased risk of cardiovascular events or mortality. The multivariate regression analysis was performed by six studies, and the risk of developing adverse outcomes remained significant after the analysis in four of these studies. The result of the meta-analysis [HR = 2.28 (1.70-3.05), p < 0.001] indicated that there is a significant association between high levels of cystatin C and the risk of mortality in individuals with normal renal function. CONCLUSION: There is a significant association between high levels of cystatin C and the development of cardiovascular events or mortality in individuals with normal renal function. PMID- 30281694 TI - Mortality for Critical Congenital Heart Diseases and Associated Risk Factors in Newborns. A Cohort Study. AB - BACKGROUND: Congenital heart diseases are the most common type of congenital defects, and account for more deaths in the first year of life than any other condition, when infectious etiologies are ruled out. OBJECTIVES: To evaluate survival, and to identify risk factors in deaths in newborns with critical and/or complex congenital heart disease in the neonatal period. METHODS: A cohort study, nested to a randomized case-control, was performed, considering the Confidence Interval of 95% (95% CI) and significance level of 5%, paired by gender of the newborn and maternal age. Case-finding, interviews, medical record analysis, clinical evaluation of pulse oximetry (heart test) and Doppler echocardiogram were performed, as well as survival analysis, and identification of death-related risk factors. RESULTS: The risk factors found were newborns younger than 37 weeks (Relative Risk - RR: 2.89; 95% CI [1.49-5.56]; p = 0.0015), weight of less than 2,500 grams (RR: 2.33 [; 95% CI 1.26-4.29]; p = 0.0068), occurrence of twinning (RR: 11.96 [95% CI 1.43-99.85]; p = 0.022) and presence of comorbidity (RR: 2.27 [95% CI 1.58-3.26]; p < 0.0001). The incidence rate of mortality from congenital heart disease was 81 cases per 100,000 live births. The lethality attributed to critical congenital heart diseases was 64.7%, with proportional mortality of 12.0%. The survival rate at 28 days of life decreased by almost 70% in newborns with congenital heart disease. The main cause of death was cardiogenic shock. CONCLUSION: Preterm infants with low birth weight and comorbidities presented a higher risk of mortality related to congenital heart diseases. This cohort was extinguished very quickly, signaling the need for greater investment in assistance technology in populations with this profile. PMID- 30281695 TI - Independent Predictors of Late Presentation in Patients with ST-Segment Elevation Myocardial Infarction. AB - BACKGROUND: In patients with acute ST-segment elevation myocardial infarction (STEMI), the time elapsed from symptom onset to receiving medical care is one of the main mortality predictors. OBJECTIVE: To identify independent predictors of late presentation in patients STEMI representative of daily clinical practice. METHODS: All patients admitted with a diagnosis of STEMI in a reference center between December 2009 and November 2014 were evaluated and prospectively followed during hospitalization and for 30 days after discharge. Late presentation was defined as a time interval > 6 hours from chest pain onset until hospital arrival. Multiple logistic regression analysis was used to identify independent predictors of late presentation. Values of p < 0.05 were considered statistically significant. RESULTS: A total of 1,297 patients were included, with a mean age of 60.7 +/- 11.6 years, of which 71% were males, 85% Caucasians, 72% had a mean income lower than five minimum wages and 66% had systemic arterial hypertension. The median time of clinical presentation was 3.00 [1.40-5.48] hours, and approximately one-quarter of the patients had a late presentation, with their mortality being significantly higher. The independent predictors of late presentation were Black ethnicity, low income and diabetes mellitus, and a history of previous heart disease was a protective factor. CONCLUSION: Black ethnicity, low income and diabetes mellitus are independent predictors of late presentation in STEMI. The identification of subgroups of patients prone to late presentation may help to stimulate prevention policies for these high-risk individuals. PMID- 30281696 TI - Organization of the cancer network in SUS: evolution of the care model. AB - In the current context of epidemiological transition, demographic changes, changes in consumption and lifestyle habits, and pressure on care costs and organized health systems for acute conditions, the Integrated Care Model by Shortell has become a conceptual reference in the search for new methods to manage chronic conditions by focusing on the health conditions of a given population that must be addressed by a set of institutions organized into networks. Within the last 15 years, cancer has gone from the third- to the second leading cause of death in the State of Sao Paulo and has shown a gradual increase in the number of new cases; it has thus become a relevant issue for public health and health management. The model adopted by the State for the organization of the cancer care network was the motivation for this study, which aimed to evaluate the evolution of the model of care for cancer patients within the Unified Health System (Sistema Unico de Saude) based on the integrated care model. Since 1993, the year that cancer was first considered highly complex in the Sistema Unico de Saude by the Ministry of Health, it has been possible to observe a progressive orientation towards the integral and integrated care of patients with cancer. In the State of Sao Paulo, the active participation of qualified service providers through a Technical Reference Committee showed that experts could contribute to the definition of public policies, thereby providing a technical base for decision making and contributing to the development of clinical management.

AB - OBJECTIVE: The purpose of this study was to evaluate the clinical outcome and costs after the implementation of robotic surgery in the treatment of endometrial cancer, compared to the traditional laparoscopic approach. METHODS: In this prospective randomized study from 2015 to 2017, eighty-nine patients with endometrial carcinoma that was clinically restricted to the uterus were randomized in robotic surgery (44 cases) and traditional laparoscopic surgery (45 cases). We compared the number of retrieved lymph nodes, total time of surgery, time of each surgical step, blood loss, length of hospital stay, major and minor complications, conversion rates and costs. RESULTS: The ages of the patients ranged from 47 to 69 years. The median body mass index was 31.1 (21.4-54.2) in the robotic surgery arm and 31.6 (22.9-58.6) in the traditional laparoscopic arm. The median tumor sizes were 4.0 (1.5-10.0) cm and 4.0 (0.0-9.0) cm in the robotic and traditional laparoscopic surgery groups, respectively. The median total numbers of lymph nodes retrieved were 19 (3-61) and 20 (4-34) in the robotic and traditional laparoscopic surgery arms, respectively. The median total duration of the whole procedure was 319.5 (170-520) minutes in the robotic surgery arm and 248 (85-465) minutes in the traditional laparoscopic arm. Eight major complications were registered in each group. The total cost was 41% higher for robotic surgery than for traditional laparoscopic surgery. CONCLUSIONS: Robotic surgery for endometrial cancer presented equivalent perioperative morbidity to that of traditional laparoscopic surgery. The duration and total cost of robotic surgery were higher than those of traditional laparoscopic surgery.

AB - The effects of randomness, an unavoidable feature of intracellular environments, are observed at higher hierarchical levels of living matter organization, such as cells, tissues, and organisms. Additionally, the many compounds interacting as a well-orchestrated network of reactions increase the difficulties of assessing these systems using only experiments. This limitation indicates that elucidation of the dynamics of biological systems is a complex task that will benefit from the establishment of principles to help describe, categorize, and predict the behavior of these systems. The theoretical machinery already available, or ones to be discovered to help solve biological problems, might play an important role in these processes. Here, we demonstrate the application of theoretical tools by discussing some biological problems that we have approached mathematically: fluctuations in gene expression and cell proliferation in the context of loss of contact inhibition. We discuss the methods that have been employed to provide the reader with a biologically motivated phenomenological perspective of the use of theoretical methods. Finally, we end this review with a discussion of new research perspectives motivated by our results. PMID- 30281700 TI - Treatment of patients with metastatic colorectal cancer and poor performance status: current evidence and challenges. AB - Patients with unresectable metastatic colorectal cancer live for a median of three years when treated with standard therapies. While the evidence guiding cancer-directed treatment of this disease comes from phase III trials that have mostly enrolled patients with good performance status, some patients present with poor clinical conditions. The best treatment for these patients remains to be determined. We performed a systematic review of the treatment outcomes of patients with metastatic colorectal cancer and poor performance status, defined as Eastern Cooperative Oncology Group performance status >=2. Eligible articles were prospective or retrospective studies or case reports published in English, Portuguese or Spanish. We searched PubMed, EMBASE, LILACS and the Cochrane Library from onset until October 2017 using specific keywords for each search. We found a total of 18 publications, mostly case reports and retrospective studies (14 articles). One was an uncontrolled prospective trial, two were observational studies and one was an individual patient meta-analysis. Although some studies suggested benefits in terms of symptomatic response with standard chemotherapy, with good safety profiles when dose-reduced regimens were administered, a true survival gain could not be demonstrated. The scientific evidence for treating metastatic colorectal cancer patients with poor performance status is scarce, and more studies evaluating treatment for this population are necessary since this condition is not uncommon in clinical practice, particularly in the public healthcare system and developing countries and among destitute populations. PMID- 30281701 TI - Clinical perspectives of PSMA PET/MRI for prostate cancer. AB - Prostate cancer imaging has become an important diagnostic modality for tumor evaluation. Prostate-specific membrane antigen (PSMA) positron emission tomography (PET) has been extensively studied, and the results are robust and promising. The advent of the PET/magnetic resonance imaging (MRI) has added morphofunctional information from the standard of reference MRI to highly accurate molecular information from PET. Different PSMA ligands have been used for this purpose including 68gallium and 18fluorine-labeled PET probes, which have particular features including spatial resolution, imaging quality and tracer biodistribution. The use of PSMA PET imaging is well established for evaluating biochemical recurrence, even at low prostate-specific antigen (PSA) levels, but has also shown interesting applications for tumor detection, primary staging, assessment of therapeutic responses and treatment planning. This review will outline the potential role of PSMA PET/MRI for the clinical assessment of PCa. PMID- 30281703 TI - Survival and prognosis of young adults with gastric cancer. AB - OBJECTIVES: Survival data for young adults (YA) with gastric cancer is conflicting and scarce in Brazil. The aim of this study was to compare the clinicopathological factors and survival rates of younger and older patients with gastric cancer. METHODS: Hospital registries for 294 gastric cancer patients from a reference cancer hospital in Sao Paulo, Brazil, were consulted for the retrieval of clinicopathological information and follow-up time. Patients were placed into the following groups: YA (<=40 years; N=71), older adult (OA: 41 to 65 years; N=129) and elderly (E: >=66 years; N=94). Differences were assessed through Pearson's chi2 test, Kaplan-Meier analysis, Log rank test and Cox regression. RESULTS: More YA were diagnosed with advanced disease (clinical stage III/IV: 86.7% YA, 69.9% OA, and 67% E); however, fewer E patients underwent surgery (64.3% YA, 72.7% OA, and 52.4% E). The median overall survival among all patients was 16 months, and the overall survival rate was not significantly different among the age groups (p=0.129). There were no significant differences in the disease-free survival rate. Metastatic disease at diagnosis (HR=4.84; p<0.01) was associated with an increased hazard of death for YA. CONCLUSION: Overall survival was similar among age groups. Metastatic disease at diagnosis was the only factor associated with a poorer prognosis in YA. These results suggest that younger patients deserve special attention regarding the detection of early stage disease. PMID- 30281702 TI - Epidemiological science and cancer control. AB - Epidemiological methods are essential for the discovery of cancer risks and prognostic factors as well as for the evaluation of cancer prevention measures. In this review, we discuss epidemiological surveillance procedures for data collection and processing to guide and evaluate the consequences of anticancer efforts for populations, assess the identification of cancer risk factors, examine barriers to cancer screening and recommended rules for early diagnosis programs. Epidemiological studies have shown that hindrances to cancer information assessment are currently encountered in developing countries. Known cancer risk factors include social determinants, lifestyle factors, occupational exposures, infectious agents, and genetic and epigenetic alterations. Challenges remain in studying the effectiveness of cancer screening; screening can have detrimental effects, and few cancers clearly benefit from screening. Currently, epidemiology faces the challenge of dealing with distinct levels of data, including factors related to social status, lifestyle and genetics, to reconstruct the causal traits of cancer. Additionally, translating epidemiological knowledge into cancer control demands more implementation studies in the population. PMID- 30281704 TI - Clinical stage and histological type of the most common carcinomas diagnosed in young adults in a reference cancer hospital. AB - OBJECTIVES: Cancer in young adults represents a great challenge, both biologically and socially, and understanding the unique characteristics of neoplasms in this age group is important to improving care. We aimed to evaluate the most common carcinomas and their characteristics, such as histological type and clinical stage, in young adults in the largest cancer hospital in Latin America. METHODS: The hospital registry was consulted for the period between 2008 and 2014. Young adults were defined as individuals aged 18 to 39 years, and older adults were defined as individuals aged 40 years and older. Differences between age groups were assessed through chi-square tests. RESULTS: Of the 39,389 patients included, 3,821 (9.7%) were young adults. Among the young adults, the most frequent cancer types were the following: breast, lymph node, colorectal, thyroid, testicle, hematopoietic and reticuloendothelial, uterine cervix, brain, soft tissue and stomach; these sites accounted for 74.5% of the observed tumors. Breast, colorectal and stomach cancers were more frequently diagnosed at advanced stages in young adults than in older adults (p<0.001). The most common histological types were infiltrating ductal carcinoma (86.12%) for breast cancer, adenocarcinomas not otherwise specified (45.35%) for colorectal cancer, squamous cell carcinoma not otherwise specified (65.26%) for uterine cervix cancer, signet ring cell adenocarcinomas (49.32%) for stomach cancer and adenocarcinomas not otherwise specified (50.79%) for lung cancer. CONCLUSION: Young adults are diagnosed with cancer at more advanced stages, indicating that health professionals should be aware of cancer incidence in this age group. It is necessary to develop a better understanding of cancer in young adults and to implement dedicated health care strategies for these patients. PMID- 30281705 TI - Vaccine confidence and hesitancy in Brazil. AB - Despite the overall benefits of immunization, vaccine hesitancy has been a growing trend and has been associated with the resurgence of vaccine-preventable diseases. The aim of this study was to assess vaccine confidence and hesitancy in Brazil, as part of a wider project to map vaccine confidence globally. One thousand subjects were interviewed, either online or face-to-face, based on a general questionnaire regarding perceptions on vaccines and vaccination. Further exploratory questions were used with the subset of respondents who were parents of children aged under 5. Such questions extracted information regarding vaccination behavior, opinions on vaccination and government health services, and vaccine hesitancy. Reasons for hesitancy were classified as relating to confidence, convenience and/or complacency, and the population was also analyzed socio-demographically. The results showed that overall confidence in immunization was higher than confidence in family planning services, community health workers and emergency services. Seventy-six people reported hesitancy to vaccinate. The commonest reasons for hesitancy were issues with confidence (41.4%), efficacy/safety of the vaccine (25.5%) and concerns about adverse events (23.6%). The sociodemographic analysis revealed that vaccine hesitancy was associated with marital status, level of education and income. Despite overall vaccine confidence being high, a clear trend toward lower levels of confidence was associated with higher levels of hesitancy, which warrants on-going monitoring, due to the dynamic and changing nature of vaccine hesitancy. PMID- 30281706 TI - Effects of smoking on tooth loss among individuals under periodontal maintenance therapy: a systematic review and meta-analysis. AB - Dental mortality has been reported by longitudinal studies on periodontal maintenance therapy (PMT), but the independent effect of smoking on tooth loss (TL), adjusted for important confounding variables, has been poorly evaluated. This systematic review aimed to assess and analyze the isolated effect of smoking TL among individuals undergoing PMT. Electronic, manual, grey literature, and recent articles (from April 2018) were searched, with no restriction regarding language; respective dates of publication were included. Epidemiological clinical studies reporting TL data among smokers undergoing PMT in comparison to nonsmoker control groups were selected. Methodological quality was assessed using the Newcastle-Ottawa Scale. Meta-analysis was performed, as well as I2 heterogeneity and sensitivity tests. Evidence quality was assessed using GRADE (Grading of Recommendations, Assessment, Development and Evaluation). Eleven papers were included in the systematic review: four case-control and seven cohort studies. Ten out of the 11 studies concluded that smoking was an important risk factor for the occurrence of TL. Meta-analysis of four of the cohort studies found that smokers had 3.24 times the chance of occurrence of TL than nonsmokers undergoing PMT (95%CI: 1.33-7.90). Overall, studies' risk of bias was low. The quality of the scientific evidence moderately supports that smokers undergoing PMT have a greater chance of TL than nonsmokers. PMID- 30281707 TI - Zika: heterogeneity and history.

PMID- 30281709 TI - [A proposal for the creation of a system to monitor cases of malignant mesothelioma in Curitiba, Parana, Brazil]. AB - The study proposes the creation of a system to monitor cases of malignant mesothelioma in the municipality of Curitiba, Parana State, Brazil, based on the Italian model. This diagnosis-type action-research project featured exploratory and planning phases conducted from July 2015 to May 2017. The following search tools were used: Hospital-Based Cancer Registries Integrator with specific morphologies for mesothelioma; Hospital-Based Cancer Registry with codes C38.4 and C45 of the International Classification of Diseases, 10th revision, and/or records coded by the ICD-O with topographies C38 and C48; Population-Based Cancer Registry of the Curitiba Municipal Health Department, with the same codes. The study also identified, analyzed, and adapted to the Brazilian reality the model, questionnaires, and registry software for mesothelioma from Lombardy, Italy. Fifteen cases of mesothelioma were recorded in the Hospital-Based Cancer Registries Integrator. Two cases were recorded in the University Hospital-Based Cancer Registry and 16 in the Cancer Hospital. There were 317 cases recorded in the Population-Based Cancer Registry during the same period. Although some information was complete, data were lacking on patients' occupational history, thereby preventing the determination of a causal nexus. Given a predicted increase in cases of mesothelioma in the coming decades and the response to court cases, the implementation of registries has become essential to facilitate knowledge and follow-up on the determination of the causal link and specific sources of asbestos exposure in the country. PMID- 30281710 TI - Association between the employment status and the presence of depressive symptoms in men and women in Mexico. AB - This study aims to estimate the relationship between employment status and depressive symptoms among Mexican adults, as well as to explore its differential effect by gender. Cross-sectional study of 36,516 adults between 20 and 59 years of age taken from the 2012 Mexican National Health and Nutrition Survey. Depressive symptoms were evaluated using the Center for Epidemiologic Studies Depression Scale (CES-D), and the employment status was determined a week before the survey. Logistic regression models were stratified by gender and education level and adjusted by sociodemographic and health-related conditions to estimate the association between depressive symptoms and employment status. The prevalence of clinically depressive symptoms was 7.59% for men and 18.62% for women. In the case of men, those who were unemployed were more likely to present depressive symptoms (OR = 1.66; 95%CI: 1.08-2.55) than those who were working. For women, employment status is not associated with the presence of depressive symptoms, except in students (OR = 1.57; 95%CI: 1.02-2.43) compared with those who were working. In both genders, disability preventing one from working was associated with depressive symptoms. Although being employed has been reported to be associated with lower levels of psychiatric morbidity, the estimated effect is different for men and women. Occupational health policies should consider these conditions. PMID- 30281711 TI - Trends in mortality from chronic obstructive pulmonary disease in Rio de Janeiro and Porto Alegre, Brazil, 1980-2014. AB - OBJECTIVE: to analyze age-period-cohort (APC) effects on mortality from chronic obstructive pulmonary disease (COPD) in the municipalities of Porto Alegre, RS, and Rio de Janeiro, RJ, Brazil, between 1980 and 2014. METHODS: this was a time series study using corrected Mortality Information System (SIM) data; APC effects were estimated by Poisson regression, in relation to the 1935 cohort. RESULTS: relative risk (RR) of death due to COPD for males decreased in the most recent birth cohort (1970-1974) in Porto Alegre (RR=0.39; 95%CI 0.32;0.48) and Rio de Janeiro (RR=0.42; 95%CI 0.38;0.48); while among women an increase in risk of death due to COPD was observed in Rio de Janeiro in more recent cohorts (RR=1.41; 95%CI 1.20;1.67). CONCLUSION: risk of death due to COPD decreased among men, while risk among women in Rio de Janeiro increased. PMID- 30281712 TI - Oral health status of pregnant and puerperal women in the municipality of Feira de Santana, at three different times between 2005 and 2015. AB - OBJECTIVE: to evaluate the oral health condition of pregnant/postpartum women attending public services in the city of Feira de Santana, BA, Brazil, at three different times between 2005 and 2015. METHODS: this is a study socioeconomic and demographic characteristics, health condition and health care, lifestyle and oral health status of 1,245 participants obtained from a database of three previous investigations: I Intervention Study (2005-2007); II Case-Control Study (2010 2011); III Case-Control Study (2012-2015). RESULTS: comparing the three periods, the frequency of gingivitis (24.41% versus 8.90% versus 5.77%; p<0.01) and periodontitis (44.64% vs 9.16% vs 11.55%; p<0.01) was found to decrease; the worst dental conditions regarding the number of teeth present, healthy and extracted and the DMFT index were found in period III compared to period II. CONCLUSION: an improvement was seen in the participants' periodontal condition over time, which coincides with the implementation of policies pertaining to women's health, oral health and income redistribution in this city. PMID- 30281713 TI - Leukemia mortality trends in children and adolescents in Brazilian state capitals: 1980-2015. AB - OBJECTIVE: to analyze the temporal trend of leukemia mortality in children and adolescents under 20 years old, in Brazilian state capitals and Federal District, between 1980 and 2015. METHODS: this was a descriptive time series study; age standardized leukemia mortality rates were calculated; the Prais-Winsten regression model was used. RESULTS: leukemia mortality rates fell from 2.73 to 1.58 per 100,000 inhabitants aged under 20 years in the period studied (annual percentage variation of -7.06%: 95%CI -8.61;5.49), with differences between capitals; there was a reduction in magnitude in all age groups - 0-4 years (9.17%: 95%CI -11.58;-6.69), 5-9 years (-9,27%: 95%CI -11.90;-6.56), 10-14 years (-4.86%: 95%CI -6.69;-3.00) and 15-19 years (-3.77%: 95%CI -5.22;-2.31). CONCLUSION: there was a falling trend in pediatric leukemia mortality rates, although it was unequal between the capitals, indicating the need for measures to minimize regional differences. PMID- 30281714 TI - Hospitalization for Ambulatory Care Sensitive Conditions in children under five years old in Santa Catarina State, Brazil, 2012: a descriptive study. AB - OBJECTIVE: to describe proportions and rates of hospitalization for Ambulatory Care Sensitive Conditions (ACSC) among children under 5 years old, in Santa Catarina State, Brazil, 2012. METHODS: this is a descriptive study using Brazilian National Health Service Hospital Information System (SIH/SUS) data, classified according to the Brazilian ACSC List. RESULTS: a total of 32,445 children aged <5 years old were hospitalized, 25,7% of whom were ACSC cases, representing a rate of 20.1/1,000 inhabitants in the same age group; the main causes were infectious gastroenteritis and complications (26.7%), bacterial pneumonia (22.2%) and pulmonary diseases (16.9%); there was a higher hospitalization rate due to ACSC in males (21.1/1,000), and in children <1 year old (43.8/1,000). CONCLUSION: The results showed that the State of Santa Catarina had lower rates and proportions than those found in other Brazilian studies, even though ACSC were the cause of one quarter of hospitalizations in children aged <5 years. PMID- 30281715 TI - Women screened for breast cancer: follow-up through Health Information Systems, Brazil, 2010-2012. AB - OBJECTIVE: to describe the two-years follow-up of women with screening mammography showing lesions suspected or highly suspected of malignancy in the city of Rio de Janeiro, Brazil. METHODS: this was a descriptive study of the care line using Health Information Systems (SIS) data on women who underwent screening mammography in the Brazilian National Health System (SUS) in the second half of 2010. RESULTS: of the 206 women studied, 13.1% had their mammograms requested by Primary Health Centers; during follow-up 102 (49.5%) were identified on at least one SIS; of these, 12 had biopsy information, all of which was positive for breast cancer; 93 had treatment, one of whom had benign disease; 12 died from breast cancer; the proportion of women identified as having treatment was higher among those with suspected high malignancy and palpable lesions (p<0.01). CONCLUSION: information on the breast cancer care line was partially recovered through SIS records.

PMID- 30281717 TI - Mortality by road traffic accidents in adolescents and young people, Brazil, 1996 2015: will we achieve SDG 3.6? AB - This paper aims to analyze the main characteristics of Road Traffic Accidents (RTA) mortality in Brazil for the period 1996-2015, focusing on the 10-29 years' age group. This is a two-step study consisting of (i) a bibliographic review on the topic of traffic violence in Brazil, and (ii) a study on RTA mortality in the Mortality Information System (SIM). The former situates the state of the art of scientific production on the theme and produces the theoretical reference for the analysis of the latter. During the period, about 39,000 people died by RTA, of which about 13,200 adolescents and young people died. The country should curb mortality to somewhere around 19,500/year and, among adolescents and young people, to 6,500/year to achieve SDG 3.6. With the establishment of the Brazilian Traffic Code (CTB), RTA mortality rate fell between 1997 and 2000. The rate increased in the subsequent decade. The focus on adolescents and young people help us understand that, in the post-CTB and Prohibition, male black and brown motorcyclists became the main victims. The literature provides data analysis and shows that reduction is currently submitted to an articulated discussion that involves worker's health, gender, employment, urban mobility and advertising policies. Concerning SDG, this means that achieving SDG 3.6 is a process that involves interacting with policies targeting other SDGs. PMID- 30281718 TI - The 2030 Agenda as a development tool for young people in Argentina. AB - Youth and adolescent populations constitute a critical set in global population. They are important to development agendas not for their quantity, but for other types of problem that favour the intergenerational reproduction of poverty and establish inequality gaps that accentuate processes of "de-institutionalisation" and "de-socialisation" of these populations and others: education systems insufficiently adapted to the current world of work or to the mass schooling of young people from vulnerable households; precarious labour markets, which many young people enter with poor qualifications; or socioenvironmental conditions that severely affect the health conditions of youth in marginal neighbourhoods. The 17 Sustainable Development Goals clearly signal the path forward for coming years, as well as highlighting the need for stronger, more innovative public policies to ensure "that no young people will be left behind". The 2030 Agenda represents a unique opportunity for the State, private sector, civil society and the international cooperation system to harness positive synergies to improve young people's quality of life. PMID- 30281719 TI - The production of victims as entrepreneurs of their social redemption: young people, control and involvement. AB - Drawing on the results of an ethnographic study and group interviews with young people and social project coordinators from favelasin Rio de Janeiro, this article discusses the association between youth and vulnerabilities and its possible consequences for the reinforcement of negative stereotypes of poor young people through discourses that emphasize self-management. It explores the notion of production of victims as entrepreneurs of their social redemption by promoting reflection on the use of the category involved in crime, disseminated in the common sense as a new form of criminal labeling. The article addresses material and symbolic investments in poor young people, beneficiaries of so-called social projects, reflecting on the maneuvers of meanings that veil the temporality of these initiatives, characterized by moralistic overtones of merit and salvation. The fear of dying or "remaining", of not finding a job, and a series of other fears are the focus of this reflection, which seeks to broaden the debate over institutional initiatives directed at young people. PMID- 30281720 TI - Global burden of disease among teenagers in Uruguay and its comparison with Latin America and the Caribbean. AB - INTRODUCTION: Adolescence is considered a healthy stage of life and therefore little studied. This study described mortality over time in teenagers in Uruguay and analysed the burden of disease at this stage of life by the measure of Years of Life Lost by Premature Death in Uruguay and by comparison with rates in Latin America and the Caribbean by sex, cause and sub-region. METHODOLOGY: Secondary data sources used were the national registry of deaths in Uruguay, the first Global Burden of Disease study in Uruguay and the information on the data visualisation page of the Institute of Metrics and Health Evaluation. Data were extracted by the authors and displayed in tables and graphs. RESULTS: Teenager mortality held roughly stable between 1997 and 2015. More years were lost to premature death among Uruguayan men, the main causes being traffic accidents, self-inflicted injuries and violence. The same behaviour occurs throughout the region. CONCLUSIONS: The social determinants of health connected with poverty and inequality play a role in the development of depression, risky and violent behaviour, which possibly explain the loss of years due to premature death in adolescence. PMID- 30281721 TI - An approach to suicide among adolescents and youth in Brazil. AB - This essay article examines suicide among young people in Brazil on the basis of Durkheim's classical approaches as revisited in current discussions of social integration networks. It presents arguments regarding the behaviour of suicide mortality rates in the light of classical public health assumptions as to social causality in processes of health and illness. The mortality rates, updated in line with international statistics, review of data in Brazilian studies and recent series for Brazil, reveal suicide "aptitudes" by age, sex and social group. The linear and non-linear nature of the trends are treated in the context of pathways in complex social systems. Current data were prospected in the Ministry of Health'sNational Mortality Information System and World Health Organisation databases. In this policy analysis study, a conceptual outline was built up from classical theory updated to the present-day context, analysis of data relevant to the study object and observation of target groups for comprehensive, inclusive policies. The results of this analysis reveal that adolescents and young people are highly liable to growing, sustained, high-impact vulnerability to suicide. PMID- 30281722 TI - Young population, sexually-transmitted diseases and rights. National and regional scenario in Argentina. AB - In the context of social and demographic studies of sexual and reproductive health, this paper discusses the situation of young people in Argentina, emphasizing the problems revolving around Sexually Transmitted Diseases (STDs) and the compliance with sexual rights. This work aims to study the calendars and characteristics of the onset of sexual life in young Argentinean people and to describe the current situation of knowledge, practices, and access related to sexual life. Based on data from the National Survey on Sexual and Reproductive Health ( 2013) we worked with the universe of young people between 15 and 29 years of age (n = 2,084 women, n = 1,872 men, without weighting) and analyzed the differences in the calendars of the onset of sexual life, as well as the knowledge and prevention of STDs by gender sex, age groups, household income and geographical regions.A national scenario was found featuring marked tendencies in the calendars of first sexual intercourse by gender sex, as well as in the knowledge about STDs. However, the analysis by region and household income in each gendersex showed high heterogeneities, which would indicate certain limitations in the access to sexual education and the effective compliance of people's rights, as well as an increased risk to contracting STDs in specific social groups.

AB - OBJECTIVE: To characterize the scientific production on adolescent health policies and programs in Brazil and Portugal in the period 2010-2017. METHOD: This is a literature review based on the Scoping Review method. The research guidingquestion was: "How is the scientific production on adolescent health policies and programs in Brazil and Portugal characterized?"Search was carried out in October 2017 on the BVS, EBSCO and Google Scholar platforms. RESULTS: Twenty-two studies were selected, namely, 17 Brazilian and 5 Portuguese. Seven cross-cutting thematic categories were identified, as follows: policy and program evaluation; health promotion and education; mental health; sexual and reproductive health; violence; oral health and nutritional health. We canconclude that, albeit in different social contexts, the themes reflect traditional areas of intervention of policies and programs, except for those arising from the phenomenon of structural violence, markedly present in the Brazilian reality. Also, the lack of emerging issues such as gender identities, migratory flows, and morbimortality from external causes reveal a possible care gap in policies and programs and a necessary field to be explored. PMID- 30281724 TI - National Policy for Comprehensive Health Care for Adolescents Deprived of Liberty: an analysis of its implementation. AB - The realization of the right to health of adolescents and young people deprived of their liberty in Brazil is a complex task that places us before health inequities and interventions on their social determinants of health. Therefore, this study sought to contribute to a discussion about the right to health of this population, based on the analysis of the implementation of the Comprehensive Healthcare Policy for Adolescent Offenders (PNAISARI). This is an analytical approach, using documentary analysis of legal frameworks and policy monitoring and evaluation data. In short, the results suggest that the policy strengthens the realization of the right to health of this population. However, its implementation must be promoted and qualified so that access to health care is, in fact, a reality in all states and municipalities.

AB - This paper presents an analysis of the symbolic conditions which govern health care provision in the Scottish prison system. The paper considers the wider context of Scottish prisons, where health care provision follows a similar structure both in juvenile and adult prisons. Our intention is to provoke a debate about the doxa (Bourdieu, 1977), which underlies decision making in respect of health care in prison, in a political environment where pragmatism, allied to the 'pathologisation' of social policies, health and criminal justice has been a hegemonic force.

RESULTS: cigarette smoking held stable, while use of other tobacco products increased by 18%. Regular alcohol use declined from 27.3% (2009) to 23.2% (2015). Drug experimentation increased, while family supervision produced protective effects against tobacco, alcohol and drug use. All indicators of violence increased, including involvement in fights where someone used a firearm or melee weapon. Diet and physical activity displayed predominantly unhealthy habits: (only 20% exercised for an hour or more daily). Sexuality: condom use at first intercourse decreased from 75.9% to 66.2%. Half the students had used a health service in the prior 12 months. CONCLUSION: exposure to risk factors, including alcohol, unsafe sex and violent behaviour and conditions, is high in adolescence, making it important to adopt public policies and inter-sectoral actions that are plural and open to singularity in order to protect the health of adolescents and youth.

AB - The Health at School Programme is a Brazilian inter-sector policy resulting from a partnership between the Ministries of Health and Education to expand health actions to public school students, with a view to the comprehensive education of primary and lower middle school students. This qualitative study was carried out in 2016 to investigate Brazilian schoolchildren's perceptions of activities under the Health at School Programme. Data were collected from schoolchildren eleven to fourteen years of age using the written report (essay) as the instrument. Analysis of the reports highlighted two themes: 1. the Health at School Programme as care, and 2. the Health at School Programme as benevolence. For some, the activities meant the possibility of health care, of identifying problems and arranging solutions, and the opportunity for gaining information and learning that may be beneficial in maintaining health - the offer was received passively, however; for others, they were a blessing, a favour, for which they showed their gratitude. The schoolchildren were passive and receptive, without being proactive enough to produce their own health. Co-responsibility seems to be a seed that is still germinating. PMID- 30281728 TI - The prevention of violence in interdisciplinary programs implemented in Brazilian and Portuguese schools. AB - This paper aims to understand how and to what extent interdisciplinary teams supporting public schools in the Brazilian and Portuguese context characterize and develop violence prevention actions. The research was carried out from an exploratory study through interviews with 24 professionals and later, a thematic analysis was done. The results indicate that prevention is always pointed out as a possibility in the Portuguese Program; in the Brazilian program, in addition to prevention-oriented discourses, limits regarding the realization of preventive activities in schools are also mentioned. In the locations investigated, flagged prevention actions are shown incipiently when compared to actions advocated by the WHO and the Pan American Health Organization. It is argued that a more strategic vision of the Ministry of Education and the Education Secretariats could contribute to avoid the sole accountability of schools concerning prevention of violence and thus enhance the decline of this phenomenon and favor its effects in the long term.

AB - OBJECTIVE: To verify the association between negative self-perception of health and school violence in adolescent students of the Municipality of Olinda (PE), Brazil. METHODS: This is a cross-sectional, analytical and school-based study with a sample consisting of 2,614 adolescents selected through a strategy of random sampling in conglomerates. The information was obtained through the questionnaire "Youth Risk Behavior Survey" from which the issues of violence and self-perceived health were retrieved. Data were tabulated by Epi-data version 3.1 program and transcribed for SPSS version 22. The Chi-square test and the stepwise binary logistic regression model were used for data analysis. RESULTS: We observed that 26.7% of adolescents had a negative self-perception of health, and this was greater among girls. Concerning school violence, negative self perception was associated with feelings of sadness, suicidal thoughts, bullying at school, robbery at school and safety at school. Gender and age were also associated (p < 0.05). CONCLUSION: We reinforce the need for culture and peace actions in adolescence, involving the school environment to reflect on poor health assessed by adolescents and reduce the rate of violence.

AB - Through anthropological, ethnographic research, this paper seeks to reflect on the dynamics of the daily functioning of a public health service specialized in the treatment of eating disorders, as well as on the process of illness experienced by adolescents who publicly face anorexia nervosa. The Eating Disorders Program observed in Rio de Janeiro provides both outpatient care and hospitalization. Fieldwork provided the knowledge about care provided to adolescents and their families, as well as the difficulties experienced by the multi-professional team. The closer coexistence of the researcher and health services facilitated the identification of the many challenges that permeate the health professional-user relationship, professional lack of motivation in the face of the complex disease, lack of qualification to treat adolescents, and other obstacles. We seek to stress the importance of this theme for the Brazilian Public Health, with the development of guidelines to orient health services, as well as public health policies that promote the establishment of programs, actions and activities aimed to give visibility and ensure rights for people with eating disorders in the country.

AB - This article, based on doctoral research, aims to understand and draw attention to forms of social participation by young people living in a peripheral community on the coast of Sao Paulo State. It also examines the manners of health production encountered by the subjects themselves, to reveal how young people have approached this in a context of marked inequality. The young study participants were involved in the activities of an NGO and a hip hop group, where the researcher was placed. The results were constructed on the basis of observations recorded in field diaries and semi-structured interviews, and analysed using the Depth Hermeneutics methodology. They indicate that building community ties expresses the participation of young people and contributes to tackling inequalities and social exclusion. Participation in groups has proven potent and able to shape processes of autonomy, self-care and care for others. However, they appear as isolated initiatives by other institutions. It is also challenging to think of ways of understanding young people's participation, participating together with them in their lives in their contexts, making for horizontal relationships and surmounting the ideas of homogenisation, control and tutelage of this population.

AB - This paper discusses the topic of first sexual intercourse in adolescence focusing on the course of ten young girls with experience of induced abortion living in a favela in Rio de Janeiro. The analysis uses the description of the process of entry into sexuality as a strategy to elucidate the context of pregnancy and the first clandestine abortion in the affective-sexual path of girls interviewed. The first sexual intercourse is a realm of sexuality and social life involving socialization, interpretation of rules and meanings, system of attitudes, ways of approximation, control and modeling of affections, emotions and gender relationships. The results showed that the age difference between couples in sexual initiation is significant, clarifying the context in which decisions on contraceptive methods, pregnancy and abortion were held. We noted that adolescents subject to difficult decisions about their sexuality and reproduction at a time of life where they still lack sexual and reproductive experience. The data collected show the importance of strengthening of public policies, discussions on gender and adolescent sexual and reproductive rights in many spheres of society, such as schools, family and other institutions.

AB - INTRODUCTION: Health education with adolescents is a challenge. Serious games are considered strategic tools, and their effectiveness is related to the pedagogical model adopted. Health education can promote leadership and autonomy, especially since is based on Paulo Freire's Pedagogy as the theoretical foundation. OBJECTIVE: To analyze the contributions of the DECIDIX serious game for educational purposes, supported by Paulo Freire's foundations, applied to health education with adolescents in the sexual and reproductive field. METHODS: Data were acquired through the validation of DECIDIX, which was carried out in two stages: i) with adolescents, and, ii) with health and education professionals. Data were registered through an audio recording of interventions; focus group; interviews and (participant and non-participant) observation. Also, data were qualitatively coded and categorized. Theoretical approach: Paulo Freire's theoretical foundations supported both, DECIDIX development and the analysis of its effectiveness. RESULTS: DECIDIX is a tool that assists the educator in educational activities using Freire's constructs, aiming the establishment of horizontal and dialogical relationships between educators and adolescents, and also, promoting experiences to develop critical reflection and autonomy.

AB - This study evaluated oral hygiene habits and their association with sociocultural, environmental factors and factors related to the use of dental services among Quilombola and non-Quilombola rural adolescents from inland Bahia. Thiswas a cross-sectional study conducted in 2015. Prevalence and prevalence ratios were estimated for the outcomes and multiple Poisson regression analysis with robust variance was performed. We interviewed 390 adolescents, of which 42.8% were Quilombola. Poor tooth brushing and non-flossing were found in 33.3% and 46.7% of adolescents, respectively. Poor tooth brushing was increased by male gender (PR = 1.45), not living with both parents (PR = 1.45), lower hand hygiene habit (PR = 1.72) and worse oral health self-assessment (PR = 1.38). Non-flossing was associated with economic level E (PR = 1.54), older age (PR = 0.91), lower hand hygiene habit (PR = 1.53) and worse oral health self-assessment (PR = 1.33). Different associated factors were observed between Quilombola and non-Quilombola. It is necessary to consider the specificities of the populations for the promotion of adolescent oral health and the importance of the intersectoriality between education and health and care to families. PMID- 30281735 TI - Heteronomy in adolescent health: an integrative literature review. AB - Adolescents' health rights are not restricted to having their demands understood, but require their being respected as autonomous subjects and the agents of their own care. However, considering adolescents' rights in terms of their autonomy in the day-to-day of the health care service, the situation is precarious as a result of heteronomy, subjection of the individual to the will of others. A search for articles was conducted in the Scopus, PubMed and BVS databases, cross referencing with the descriptors: "saude do adolescente" ("adolescent health") , "responsabilidade civil" ("civil responsibility") and "responsabilidade parental", ("parental responsibility"). After inclusion and exclusion criteria were applied, 32 studies were analysed. The results indicated that adolescents are generally not consulted in parents' or guardians' decision making about their health care, and also that the family relationship is established under rules maintained by punishment, accountability and control, while dialogue is neglected. In that light, there is a need for measures to protect and promote autonomy, while academic discussion of the relation between adolescent health and heteronomy, considering the fields of human rights and health, requires more in depth evaluations with a view to providing legal guidance on parent's day-to-day role in adolescent health care.

AB - The objective of the present study was to examine the magnitude of gender differences in activity limitations among the elderly, and the effect of the health and social individual factors and the context of social gender inequality in Europe. Cross-sectional design was performed. The study population included residents aged 60 years or over from 17 countries that participated in the Survey of Health, Ageing and Retirement in Europe conducted in 2010-13 (n = 49,685). Gender differences in activity limitation in each country was estimated. For multilevel analysis adjusted linear mixed effect models were used, where the intercept and 'sex' were considered random effects, with the 95% confidence intervals. The activity limitation index was created from a two parameter logistic combined models of item response theory. The average activity limitation index was significantly higher in women, (g10 = b1j = 0.36, p < 0.001), and was then controlled by individual and contextual factors, while the extent of these differences varied among countries. The European countries with the greatest gender differences in activity limitations were those with the greatest social gender inequalities, with women presenting a significant disadvantage. PMID- 30281737 TI - Family burden among caregivers of people with mental disorders: an analysis of health services. AB - The objective of this study was to analyze the objective and subjective levels of burden felt by family caregivers of patients who were treated at three institutions: a General Psychosocial Care Center (known as 'CAPS Geral'), a CAPS center for Alcohol and Drugs ('CAPS AD') and the Psychiatric Admissions Unit of a General Hospital ('UIPHG') in the municipality of Sobral, Ceara State, Brazil. The study included 385 caregivers, 216 of whom were in the CAPS Geral, 86 in the CAPS AD and 83 in the UPHG, and applied the Family Burden Interview Scale (FBIS BR). Excel and SPSS were used to organize and analyze the data, and a 5% significance level was applied. The results show that the general objective burden was greater for caregivers at the UIPHG. This group was also found to bear a greater objective burden with regard to caring in day-to-day life. The analysis of the subjective sub-scales showed that caregivers from the UIPHG group were most troubled by supervising problematic behaviors and also by the future and patient's type of care and medical treatment. Variables including sex and age were associated with burden. PMID- 30281738 TI - [Childhood Mental Health Problems in Primary Care]. AB - The present population study aimed at identifying the prevalence of mental health problems (MHP) and describing health services use in a sample of children attending Primary Healthcare Units (PHU) in the city of Sao Paulo. Caregivers of 825 6-11 years old children were assessed. MHP were assessed with the Strength and Difficulties Questionnaire and health services use with an adapted version of the Client Receipt Inventory Children's version. Prevalence of internalizing and externalizing MHP was 30.7% and 18.3%, respectively. Pediatricians were the most consulted health professional (56.7%) and psychologists the most consulted mental health professional (7.9%). Only 3 children were under medication treatment for MHP. The high prevalence of MHP among children in the primary care setting and the low rate of treatment constitute a public health problem. Training programs for health professionals are relevant to help identify and refer MHP cases.

AB - The scope of this article is to analyze the quality of work life of the physical therapy course teachers in the city of Goiania in the state of Goias. It involved a cross-sectional study of 65 physical therapy teachers in Goiania. The participants who had worked for less than six months in the profession and those who failed to fill out the questionnaire in full were excluded from the research. A socio-demographic and the Total Quality of Work Life (TQWL-42) questionnaire were used to assess the quality of work life. It was established that the teachers who taught in graduate courses and who held management positions presented significantly better averages than those who only taught in undergraduate courses. Satisfaction with income and with the teaching activity also showed significant results influencing the quality of work life of the participants. Work in positions and locations that allow greater autonomy, status and remuneration, as well as subjective evaluation of satisfaction with income and teaching work, influenced the quality of work life of physical therapy teachers.

AB - The objective of this research was to analyze the factors associated with the Food and Nutrition Surveillance System (Sisvan Web) coverage for children under five years of age in the municipalities of the Regional Health Inspectorate of Belo Horizonte (HRS-BH). Sisvan Web coverage data were collected from September to October 2012. Simultaneously, a "semi-structured questionnaire about the Sisvan operation" was sent to identify the technical references of municipalities studied. The coverage was calculated by dividing the number of under five-year old children covered by Sisvan by the total number of similarly under five-year old children obtained from the 2010 IBGE census. The Median Sisvan Web coverage of children in the HRS-BH municipalities was 5.59%, with coverage values ranging from 0.55% to 35.8%. Among the variables studied, the only one that revealed significant statistical association (p < 0.05) with Sisvan Web coverage was the lack of professionals to collect data. The results revealed the need for greater awareness of health managers and public health professionals about the importance of the nutritional diagnosis situation of the population through Sisvan Web.

AB - ICD-10 is the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD), a medical classification list by the World Health Organization. It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. Associations between variables were evaluated using Pearson's chi-squared test and multiple correspondence analysis. Six hundred and ninety-one (691) codes were identified related to adverse drug reactions (52.1%) and drug poisoning (47.9%). A total of 687 (99.4%) and 511 (73.9%) codes were validated in 1st and 2nd validation, respectively. There were statistically significant differences (p <0.05) between adverse reactions and drug poisoning in the variables used to characterize the reference list. The association between drug and hospital admission and death was statistically significant when stratified by type of adverse event (p <0.001). Three groupings of codes were identified in multiple correspondence analysis where there are associations between categories of response assessed. The reference list can be a useful tool in pharmacovigilance actions in Brazil.

AB - The Surveillance System for Occupational Accidents (Sistema de Vigilancia em Acidentes de Trabalho - SIVAT) established by Reference Center for Workers' Health (Centro de Referencia em Saude do Trabalhador - CEREST-Piracicaba) in 2003 represents an experience consolidated according to the guidelines formulated by the National Network for Integral Care of the Workers' Health (Rede Nacional de Atencao Integral a Saude do Trabalhador - RENAST). The present article analyzes the history and development of SIVAT at CEREST - Piracicaba from the perspective of cultural-historical activity theory. The historical data comprise interviews, documents and observations performed by the researchers. Analysis showed that the studied activity underwent two cycles of expansion. During the first cycle, CEREST actions sought to adequate the targeted companies to the legislation in vigor. During the second cycle, actions aimed at introducing changes relative to organizational determinants in the targeted companies that CEREST staff identified as causes of accidents. A new modality of formative intervention, called Change Laboratory (CL), seems to be useful to attain the goal of prevention; it involves analysis of the causes of accidents, activity remodeling and implantation of solutions by developing agency in the targeted organizations. PMID- 30281743 TI - Prevalence and factors associated with surfactant use in Brazilian Neonatal Intensive Care Units: A multilevel analysis. AB - The treatment with exogenous surfactant reduces mortality and the risk of complications in preterm newborns with Respiratory Distress Syndrome. Higher usage levels have been associated with individual and institutional factors. The study aimed to identify these factors associated with use of this technology in 16 public Brazilian Neonatal Units using logistic multilevel analysis. In a sample of 630 newborns the use at some time was 82.6%. Only 24.7% made use of this technology up to two hours after birth. An intraclass correlation of 0.30 showed that 30% of the variance in the use of exogenous surfactant could be assigned to the contextual level. In the final model, a greater severity score (SNAPPE-II) was associated with increased surfactant use (OR = 2.64), whereas being small for gestational age (SGA) (OR = 0.59) was associated with lower use of this technology. At the contextual level the number of beds in the unit >15 (OR = 5.86), units with higher complexity (OR = 1.73) or units with implemented Kangaroo Mother Care (OR = 2.91), especially units in Rio de Janeiro state (OR = 16.17) were associated with greater surfactant use. Although individual clinical features explained most of the variation in the use of this technology, factors linked to the institution were also of utmost importance. PMID- 30281744 TI - Multimorbidity, depression and quality of life among elderly people assisted in the Family Health Strategy in Senador Guiomard, Acre, Brazil. AB - This study analyzed the association between multimorbidity, depression and quality of life among the elderly in the Family Health Strategy (FHS). A cross sectional study was conducted among the elderly in the FHS in Senador Guiomard (State of Acre). The study employed the Geriatric Depression Scale (GDS-15) and the Quality of Life Questionnaire (WHOQOL-BREF). Differences in descriptive variables in elderly people with and without multimorbidity were estimated using Pearson's chi-squared test, while the associations between multimorbidity and depression and quality of life were estimated using the logistic regression technique. It was seen that elderly people with depression represented 27% of the sample, this being more prevalent among elderly people with multimorbidity than those without, the former being twice as likely to be subject to depression. Likewise, individuals with multimorbidity had a greater chance of worse quality of life in the physical, social and total quality of life domains (all with p <= 0.010), though not in the environmental domain (p = 0.493). Thus, multimorbidity in the elderly is associated with the presence of depression and poor quality of life, which imposes the challenge on the FHS of guaranteeing the elderly living out their senescence without suffering and diminished quality of life. PMID- 30281745 TI - [Biomedical knowledge and health policies: Hemolytic Uremic Syndrome and Fibromyalgia]. AB - The article deals with the construction of knowledge about diseases. The general objective is to analyze the process of constructing scientific knowledge of two diseases in comparative perspective: Hemolytic Uremic Syndrome and Fibromyalgia. The work reflects on the construction of biomedical knowledge and health policies, specifically how scientific knowledge impacts on the design of policies. Our research strategy was based on the analysis of scientific literature, health programs and bills of Argentina. The analysis was based on the axial model of diagnostic categories (semiological, morphological, explanatory and epidemiological) developed by Camargo Jr in order to detect how the distinctive features of biomedical sphere is translated into the political sphere. The investigation showed that the hierarchy given to each axis when a disease is defined at the moment of designing health policies is curcial. It also revealed that when biomedicine can not define the disease, based on their clinical and epidemiological reasoning, the roles are reversed. Then it is politics that recognizes the disease and gives the legitimacy that patients need. PMID- 30281746 TI - Guidelines for child health: language development on focus. AB - Language disorders impact on child overall development. Policy directives for the child guide on ways to follow up child development for greater efficiency and effectiveness. The aim of this paper was to identify the policies positions of the proposals on the attention to language problems in the child health field. From a documental research, national and international guidelines were reviewed in order to identify actors, objectives, contexts, motivations, arguments, justifications and proposals regarding the follow of child development and child language. We performed a critical analysis in order to explain these positions and place on discussion the arguments that support them. The results point out to consensual aspects that place the problems of child development as vulnerabilities producers. Language problems cross the boundaries of political, scientific and social matters. These issues are challenges to interdisciplinary and intersectoral work and guide the need to promote the most effective responses of public policy for people requiring language support. The link of this discussion with the concepts of life cycle and human development for achieving full citizenship requires further deepening.

AB - At the intersection of religion and health, demands for healing, liberation and exorcism express undefined discomforts that span from physical and psychiatric conditions to relational and psychological problems. To understand this growing demand in the population, this study seeks to analyze, on the one hand, the underlying conceptions of person and disease and, on the other, the therapeutics that priests and their assistants put into action, based on an ethnographic study with participant observation and in-depth interviews carried out between 2013 and 2017 in parishes in the city of La Plata and other localities of the province of Buenos Aires. The results enable us to understand that the conception of person based upon which therapeutic actions are carried out involves an expansion of the individual to the physical, psychological and spiritual planes, and that the notions of disease and wellbeing include the person, their environment and past generations.

AB - This article looks at the presence and key role of nonhuman beings endowed with intention in the diagnosis and cure of illness. Based on the framework of studies of pluralism and itineraries of healing, the article reflects on the persistence of the category of the phantom - a nonhuman entity endowed with intentionality - in such paths of curation, alongside biomedicine and its diagnostic categories. The data upon which this article is based were collected over the course of numerous ethnographic field visits carried out between 2005 and 2015 in a network of villages located in the Garhwal region of the Uttarkashi district, in the area northwest of Uttarkhand, India. Using these data, the article attempts to reflect on the reasons why patients, in certain contexts throughout the diagnosis and healing process, seek out different specialists, often at the same time.

AB - This article addresses the relationship between health and spirituality through the analysis of narratives of illnesses that occur during pregnancy and postpartum and that affect women and children in rural communities of Molinos (Calchaqui Valleys, Salta). It is based on research carried out from 2009-2017, in which 33 semi-structured interviews were conducted with women caring for children under six years of age. We focused on the way in which the interviewed women presented the sequence of events surrounding the emergence of illnesses affecting their own health and that of their children, in which organic, emotional and spiritual aspects interact in both the etiology of the illness and its treatment. We analyze as an example susto [fright] and its variations, as well as recaida [relapse] and matriz [womb]. The meanings attributed to these illnesses stress the spiritual dimension involved that justifies the use of traditional medicine resources. Our approach seeks to go beyond a taxonomic and essentialist perspective to focus on aspects involved in the process of the experience of illness. PMID- 30281751 TI - Mal paraje and mala hora: remarks on the naturalistic violence towards Andean medical knowledge. AB - The local notions of mal paraje [bad place] and mala hora [bad time] are key to explaining many illnesses in Andean medical knowledge. Notwithstanding the relevance of these notions ethnographically, neither anthropological research nor biomedical knowledge has properly dealt with these local distinctions, and have largely relegated them to the shadows. Our aim is to examine the origin of this shortcoming of anthropological and biomedical knowledge production. Our hypothesis is that such shortcoming is related to the implicit use of certain naturalistic theoretical presuppositions, both from the point of view of social sciences and from the point of view of biomedical research, producing symbolic and epistemic violence against Andean medical knowledge which we call naturalistic violence. In methodological terms we examine ethnographic data from the Aymara community of Camina (Tarapaca, Chile) and the literature produced on this topic. We focus on the notions of mal paraje and mala hora using the content analysis technique. We conclude that the main naturalistic obstacles include the treatment received by territorial entities, the relationships established among these entities and human beings (reciprocity), and the conceptions of space/time present in the diagnosis of a disease.

AB - This work describes and analyzes the trajectories and strategies in the search for healing among participants of a charismatic Catholic healing movement in Argentina. Using ethnographic research carried out between July 2009 and April 2015, the article focuses on conceptions, practices and experiences surrounding health-disease-care processes. It is highlighted that disease management requires both a cognitive and a practical response, in this case involving two primary therapeutic resources: biomedicine and religious therapies. It is also postulated that each resource is sought at specific moments in the trajectories and the passage from one to another implies a change from a restricted to a holistic notion of the health-disease-care process. PMID- 30281753 TI - [Beyond therapy and religion: a relational approach to the spiritual construction of wellbeing]. AB - Taking into account the discontinuity between the body and the soul as a manifestation of the dominant "great division" of modernity, this paper intends to reflect critically on the scope of this division in the analysis of the therapeutic dimension of New Age style spirituality. Through participant observation, open-ended interviews and shared experiences with members of a spiritual movement of Indian origin, The Art of Living, carried out between 2012 and 2017 in Buenos Aires, Argentina, we describe two processes. First, the institutional discourse of the movement and its location within public disputes regarding the tension between the therapeutic and the religious. Second, we analyze regimens of everyday relationships that produce multiple agencies and a spiritual grammar. We then suggest the importance of attending to a relational and assembled framework that challenges the more conventional dualism between the therapeutic/religious in the light of a more general contemporary process of ordinarization in the management of well-being.

AB - The identification of the body as well as the family and religion in the socialization processes of deaf people are examined based in the epistemological reflection of the symbolic relational paradigm within the framework of symbolic interactionism. A longitudinal study was carried out during the years 2016 and 2017 following ten life trajectories, chosen from a sample of narratives of deaf subjects in the urban area of Bogota (Colombia). Deaf adults who identified with contexts that could be described using the concept of alternation, had children of any age, were users of sign language and had experienced subjective processes related to Deaf culture were selected. In particular, situations of religion and health emerge in which the body is resignified in deaf adults, generating the questioning of professional interventions and discarding perceptions of exclusion in order to confer new meaning to the body as a socializing agent.

AB - The purpose of this study is to understand the meanings of religious work in the prevention of violence and in the recovery of people involved in illicit acts in a complex of shantytowns in Rio de Janeiro, Brazil. The activities of religious entities in the territory, the view of religious leaders regarding their role and that of their church, and the representations of the territory and of the people who commit violent acts were analyzed. Using a qualitative approach, participant observation and interviews of religious leaders and "converts" were conducted between 2010 and 2012. The resulting narratives were treated using enunciation analysis. The leaders emphasize the importance of their churches' actions in violent and precarious areas, while the "converts" highlight the role of evangelization in their religious conversion. However, the relationships between religion and violence are complex, involving various types of trajectories and behaviors; in this way, the strength of religious support in the conversion process is both highlighted and questioned. The text concludes that churches' actions tend to be palliative and focused on the individual and therefore do little to transform reality, with the church potentially taking on roles of social control and pacification.

AB - Multifaith rooms are an emerging model for the management and accommodation of the religious diversity that proliferates in the health field. This article examines the micropolitics of the design of multireligious spaces in hospital contexts. Drawing on recent empirical evidence and the "material turn" in the study of religion, we focus on the material negotiations that underlie the creation of these religious spaces. The article is based on an ethnographic study carried out between 2013 and 2016 using the strategy of a multiple case study (in three hospitals) in Catalan. Twelve in-depth interviews with religious leaders of different faiths and hospital staff and managers, as well as observations in multifaith spaces, were carried out. The article shows that multifaith rooms are not conciliatory and integrative per se, but rather constitute contexts of tension and contention. We conclude that an inherent conflictual dimension is part of the nature of this type of spaces and should be recognized and integrated into the management of diversity in hospital contexts.

Based on qualitative methodology and a sociological approach and carried out in 2015 and 2016, the study includes fourteen interviews with teachers, leaders and former users of the program, twelve interviews with state officials, participant observation in training courses and a corpus made up of documents related to both institutions. The emergent processes of political and religious institutionalization were analyzed according to three dimensions: a) charisma and its opposite, bureaucracy, b) the dynamic role of the second lines of leadership and c) the networked organization structures. It is concluded that points of convergence and analogies exist in the dynamics of evangelical and public institutionalization in addiction treatment.

AB - Religions have historically established ways to regulate the lives of their followers, impacting conceptions of wellbeing and health. Likewise, state agencies have incorporated a more complex definition of health, including a lack of bodily illness, stability, and social, psychological, emotional and spiritual wellbeing. Using the category of care in a broad sense, we seek to put these conceptualizations into tension in order to identify points of agreement and discrepancy among the ways of defining health and wellbeing by state and religious agents. Using a qualitative approach, content analysis of documents, participant observation and formal and informal interviews with state and religious agents were carried out in the framework of two events held in 2016 and 2017 by the Buenos Aires Provincial Office of Religions under the name Expo Promo Salud. These events were generated to make visible the actions carried out by religions in the area of health in general and problematic drug use in particular. In this way, the article seeks to analyze the ways of discursively defining care, health and wellbeing and their possible impact on the design of public policies.

AB - In recent decades, the growing interest of Westerners in the psychotropic brew ayahuasca and the participation in exotic rituals has led to the multiplication of "shamanic centers" in the Peruvian Amazon. Among these, Takiwasi is a therapeutic community that welcomes hundreds of national and foreign clients every year. This institution, created by a French physician in 1992, was originally intended to propose a therapeutic alternative for the treatment of addiction, characterized by the use of tools of Peruvian mestizo shamanism, biomedicine and clinical psychology. The diachronic evolution of the institution is however marked by the growing use of elements of the Catholic tradition. In this article, I will examine the hypothesis that these transformations can be interpreted as the effects of the globalization of the use of ayahuasca and its legal and political consequences. Thus, the case of Takiwasi underlines the role played by religious traditions and the medical field in the construction, legitimization and maintenance of new and hybrid practices that are multiplying around the use of ayahuasca.

AB - This article seeks to reconstruct how the process of institutionalization of a presbytery of non-Catholic chaplains developed as a way to adapt and interact with public institutions in Argentina, particularly health care institutions. For this purpose, qualitative interviews with religious actors trained in bioethics were carried out, in addition to participant observation in training spaces and conferences on health and bioethics and documentary analysis of training material and declarations of religious actors on issues of health and bioethics. In a context of relations of asymmetry between the State and the churches and the pluralization of the religious field, diverse needs for spiritual aide in state institutional spaces arise. It is in such a framework that this organization of chaplains gains institutional status, developing its own ethos in search of recognition, visibility and social legitimacy to offer chaplaincy services in institutions where the only chaplains recognized and funded by the State belong to the Catholic religion.

AB - OBJECTIVE: To describe first medical students' profile of the Faculdade Israelita de Ciencias da Saude Albert Einstein. METHODS: Data were collected using an electronic questionnaire during the Biostatistics course in August of 2016. The students were inquired about demographic characteristics, data on their secondary education and college entrance exams, practice of physical exercise, leisure activities done, to have a physician in the family, and specialty that they intended to pursue as a career. RESULTS: Most of the students were women aged 18 to 21 years and who were originally from the state of Sao Paulo, had received secondary education in a private school, took a course to prepare for college entrance exam, and participated in more than 5 college entrance exams in the same year they entered in the School of Medicine. The majority of participants practiced physical exercise regularly and were engaged in common leisure activities. Most of students (58%) had a physician in the family and more than half (52%) did not know which specialty to pursue as career. There was no association between relationship with a physician and the student's choice of a specialty (p=0.390). CONCLUSION: Although it was the first group of student of School of Medicine at Faculdade Israelita de Ciencias da Saude Albert Einstein who took a different admission process, our data showed that students' profile is similar to students from other colleges. PMID- 30281762 TI - What do physicians know about homosexuality? Translation and adaptation of Knowledge about Homosexuality Questionnaire. AB - OBJECTIVE: To adapt the Knowledge about Homosexuality Questionnaire to Brazilian Portuguese, and to assess knowledge of heterosexual physicians on homosexuality. METHODS: The following steps for cultural adaptation were made: translation by two independent evaluators, translation synthesis, and evaluation of semantic properties by the target population, followed by the development of a pilot study and administration of the instrument to 224 heterosexual physicians working in the Brazilian Federal District. RESULTS: The mean number of correct answers in the questionnaire was 11.8 (SD=2.81) out of 18 items, i.e., 65.5%. Catholic and evangelical physicians gave a significant lower number of correct answers compared with those who believed in other religions or who did not believe in any religion (p=0.009), and 40% of sample did not know that homosexuality is not considered a disease. CONCLUSION: This study adapted the American instrument entitled Knowledge about Homosexuality Questionnaire and provided evidence for its validation in Brazil, revealing physicians' lack of knowledge about several aspects related to homosexuality. The findings of this study may help in guiding improvements in medical training and practice. PMID- 30281763 TI - Factors associated with hospital admissions due to hypertension. AB - OBJECTIVE: To study the temporality of hospital admissions due to arterial hypertension and its associated factors. METHODS: An ecological study with secondary data on hospital admissions due to essential arterial hypertension - ICD 10, from the Hospital Information System, the Mortality Information System and and the Primary Care Information System, between 2010 and 2015. Descriptive analysis using means, proportions and linear regression. RESULTS: We recorded 493,299 hospitalizations due to arterial hypertension from 2010 to 2015, with an average annual progressive cost decrease of -7.76% and -24.21%. Of the patients admitted, 59.2% were women, 60.2% were non-white and 54.7% were older than 60 years. The mean length of stay was 4.2 days, and the hospitalization cost was R$307.60. The multiple linear regression variables that remained significant were the percentage of admissions due to primary care-sensitive conditions, the per capita income and the City Human Development Index. CONCLUSION: Hospital admissions due to arterial hypertension have an impact on the percentage of admissions due to primary care- sensitive conditions. Intensifying primary care activities, raising-awareness among professionals to the importance of integrated care, and investing in social development are crucial to change the reality of hypertension in terms of its control and complications.

AB - The aim of this study were to describe the technique of percutaneous drainage of iliopsoas abscess, and to discuss the benefits of using this minimally-invasive tool. A single center study with retrospective analysis of patients with psoas abscess confirmed by imaging scans, sent to the interventional medicine center and submitted to computed tomography and ultrasound-guided percutaneous drainage, from November 2013 to August 2016. Seven patients underwent percutaneous drainage of psoas abscess in this period. The mean initial drained volume was 61.4+/ 50.7mL (ranging from 10 to 130mL), and the mean drainage duration was 8.3+/-2.8 days (ranging from 4 to 12 days). The success rate of the percutaneous procedures was 71.5%, and two patients required re-intervention. Image-guided percutaneous drainage of iliopsoas abscess is a minimally invasive, efficient and safe procedure, and an extremely valuable technique, especially for patients who are not suitable for surgical repair. PMID- 30281764 TI - Cardiac tissue engineering: current state-of-the-art materials, cells and tissue formation. AB - Cardiovascular diseases are the major cause of death worldwide. The heart has limited capacity of regeneration, therefore, transplantation is the only solution in some cases despite presenting many disadvantages. Tissue engineering has been considered the ideal strategy for regenerative medicine in cardiology. It is an interdisciplinary field combining many techniques that aim to maintain, regenerate or replace a tissue or organ. The main approach of cardiac tissue engineering is to create cardiac grafts, either whole heart substitutes or tissues that can be efficiently implanted in the organism, regenerating the tissue and giving rise to a fully functional heart, without causing side effects, such as immunogenicity. In this review, we systematically present and compare the techniques that have drawn the most attention in this field and that generally have focused on four important issues: the scaffold material selection, the scaffold material production, cellular selection and in vitro cell culture. Many studies used several techniques that are herein presented, including biopolymers, decellularization and bioreactors, and made significant advances, either seeking a graft or an entire bioartificial heart. However, much work remains to better understand and improve existing techniques, to develop robust, efficient and efficacious methods. PMID- 30281767 TI - Advanced Education?

AB - Measuring treatments used by 202 patients with chronic low back pain in the PRECISION Pain Research Registry, this study determined the associations of opioid and nonsteroidal anti-inflammatory drug (NSAID) therapy with clinical status. More than one-fourth of patients did not use nonpharmacologic treatments for low back pain. Patients age 50-59 and 60-79 years old were more likely to use opioids than younger patients. Patients using opioids reported greater pain and back-related disability than did patients using NSAIDs. Patients concurrently using opioids and NSAIDs reported greater back-related disability and poorer quality of life than did patients using no or other pharmacologic therapy. No significant associations between pharmacologic therapy and clinical status remained after controlling for potential confounders. Neither opioids nor opioids combined with NSAIDs were more effective than just NSAIDs. Greater use of nonpharmacologic therapies and better second-line, nonopioid pharmacologic therapies appear necessary for more effective treatment of chronic low back pain.

PMID- 30281775 TI - Permanent tooth emergence: Timing and sequence in a sample of Black Southern African children. AB - OBJECTIVES: This study investigates mean age, sequence, and temporal trends of permanent tooth emergence in Black Southern African children and compares the findings with other population samples. MATERIALS AND METHODS: This community based cross-sectional study involved 639 Black Southern African children between 5 and 20 years of age. Probit analysis was used to derive the mean age at emergence of the permanent teeth. Sex and cross-population comparisons were undertaken to determine similarities and differences in emergence timing and sequence. RESULTS: Females emerged all teeth earlier except for M3s (p < .05). Black Southern Africans have earlier mean ages of emergence compared to population samples from the USA, Europe, Australia, and Asia. Sexual dimorphism was detected in the mandibular I1/M1 emergence sequence (females, M1 I1 ; males, I1 M1 ). The sequence in males is similar in both jaws to males from other sub Saharan African, USA, and European samples. Females show a similar sequence pattern in the maxilla with other sub-Saharan African, and also Australian and US females of European ancestry. There is a high frequency of polymorphism in the P1P2C1 emergence sequence, with significantly more P2P1C1 maxillary sequences seen among males. Polymorphic variation was common for the I1 M1 sequence in both males and females. DISCUSSION: Mean age of tooth emergence among Black Southern African children is similar to children from most other sub-Saharan African populations. No temporal change was seen in the mean age of emergence. Earlier permanent tooth emergence in Black Southern Africans is part of a general sub Saharan pattern that is distinct from European and Asian populations. PMID- 30281776 TI - Organization of the catecholaminergic systems in two basal actinopterygian fishes, Polypterus senegalus and Erpetoichthys calabaricus (Actinopterygii: Cladistia). AB - Cladistians are a group of basal nonteleost actinopterygian fishes that represent an interesting group for the study of primitive brain features, most likely present in the ancestral Osteichthyes. We have investigated the catecholaminergic (CA) systems in the brain of two representative cladistian species, the bichir Polypterus senegalus and the reedfish Erpetoichthys calabaricus, by means of antibodies against tyrosine hydroxylase (TH; the first enzyme in the synthesis of catecholamines) and dopamine (DA). Double immunohistofluorescence was performed for simultaneous detection of TH with nitric oxide synthase, choline acetyltransferase, calbindin, calretinin, and serotonin, aiming to accurately establish the localization of the CA neurons and to assess possible interactions between these neuroactive substances. All forebrain CA groups of cladistians are dopaminergic, whereas noradrenergic cells are located within the rhombencephalon. Distinct groups of DA immunoreactive (DA-ir) cells were observed in the olfactory bulb, subpallium, and preoptic area of the telencephalon. Hypothalamic groups were detected in the suprachiasmatic nucleus, retrotuberal and retromamillary areas and, in particular, the paraventricular organ showed immunoreactivity to dopamine but not to TH. Diencephalic DA-ir groups were detected in the prethalamus, posterior tubercle, and pretectum. A small DA-ir cell population was observed in the midbrain tegmentum only in Polypterus. CA cell groups were also located in the locus coeruleus, solitary tract nucleus, and area postrema within the rhombencephalon, the spinal cord, and the retina. The comparison of these results with other vertebrates, using a neuromeric analysis, shows highly conserved traits in all vertebrates studied but also evidences particular characteristics of actinopterygian fishes. PMID- 30281777 TI - Feasibility of Implementing Patient Priorities Care for Older Adults with Multiple Chronic Conditions. AB - Older adults with multiple chronic conditions (MCCs) receive care that is fragmented and burdensome, lacks evidence, and most importantly is not focused on what matters most to them. An implementation feasibility study of Patient Priorities Care (PPC), a new approach to care that is based on health outcome goals and healthcare preferences, was conducted. This study took place at 1 primary care and 1 cardiology practice in Connecticut and involved 9 primary care providers (PCPs), 5 cardiologists, and 119 older adults with MCCs. PPC was implemented using methods based on a practice change framework and continuous plan-do-study-act (PDSA) cycles. Core elements included leadership support, clinical champions, priorities facilitators, training, electronic health record (EHR) support, workflow development and continuous modification, and collaborative learning. PPC processes for clinic workflow and decision-making were developed, and clinicians were trained. After 10 months, 119 older adults enrolled and had priorities identified; 92 (77%) returned to their PCP after priorities identification. In 56 (46%) of these visits, clinicians documented patient priorities discussions. Workflow challenges identified and solved included patient enrollment lags, EHR documentation of priorities discussions, and interprofessional communication. Time for clinicians to provide PPC remains a challenge, as does decision-making, including clinicians' perceptions that they are already doing so; clinicians' concerns about guidelines, metrics, and unrealistic priorities; and differences between PCPs and patients and between PCPs and cardiologists about treatment decisions. PDSA cycles and continuing collaborative learning with national experts and peers are taking place to address workflow and clinical decision-making challenges. Translating disease based to priorities-aligned decision-making appears challenging but feasible to implement in a clinical setting.

AB - OBJECTIVE: To assess the impact of a cervical traction maneuver (Amr's maneuver) used in conjunction with active management of the third stage of labor (AMTSL) on the incidence of postpartum hemorrhage (PPH). METHOD: The present multicenter randomized controlled trial was conducted in Cairo between March 1, 2016, and June 30, 2017. Women aged at least 18 years who had singleton pregnancies and were candidates for vaginal delivery were enrolled. After block randomization, AMTSL was performed for all participants. Following placental delivery, Amr's maneuver using cervical traction for 90 seconds was carried out in the study group. The primary outcome, incidence of PPH (>500 mL blood loss) within 6 hours of delivery, was compared between the study and control groups in an intention-to treat analysis. RESULTS: There were 852 patients randomized to the study (n=426) and control (n=426) groups. The incidence of PPH was significantly lower in the study group compared with the control group (6 [1.4%] vs 19 [4.5%]; P=0.015). Absolute risk reduction of 3.1% (95% CI 0.8-5.6), relative risk reduction of 0.32 (95% CI 0.13-0.78), and number needed to treat of 33 (95% CI 129-18) were observed in the study group. CONCLUSION: Amr's maneuver was effective in decreasing the incidence of PPH. ClinicalTrials.gov Identifier: NCT02660567.

AB - CLINICAL QUESTION/SCENARIO: Can therapy with clindamycin and rifampicin be safely continued long term beyond the recommended 10-week course? BACKGROUND: Clindamycin and rifampicin are used in combination to treat hidradenitis suppurativa (HS). There is no data on the efficacy and safety of clindamycin/rifampicin combination therapy for HS beyond 10 weeks. METHODS: We identified the following major concerns that still lack a proper evidenced-based analysis: for rifampicin, drug-induced liver injury, interstitial nephritis, drug interaction and hepatic p450 3A4 enzyme induction; for clindamycin, the concern was community-acquired Clostridium difficile infection (CA-CDI); and experience with long-term treatment. Data sources were used as appropriate to answer the question. Systematic searches were used to assess the risk of CA-CDI and experience with long-term treatment with clindamycin. RESULTS/IDENTIFIED EVIDENCE: The risk for rifampicin-induced liver injury is highest in the first 6 weeks of treatment, whereas interstitial nephritis is primarily observed during intermittent treatment. Enzyme induction due to rifampicin is usually complete after about 2 weeks of treatment and reduces clindamycin blood levels by about 90%. Three meta-analyses identified antibiotic use as a risk factor for CA-CDI. Two of them assigned the highest risk to clindamycin. None of them stratified by length of treatment. There is extensive experience with rifampicin, primarily for the treatment of tuberculosis. Long-term experience with clindamycin is limited. DISCUSSION AND RECOMMENDATION FOR CLINICAL CARE: The analysed risks associated with a combination of clindamycin and rifampicin for hidradenitis suppurative cluster within the first 10 weeks. Treatment can be continued beyond 10 weeks, if clinically necessary. PMID- 30281780 TI - Imatinib inhibits CSF1R that stimulates proliferation of rheumatoid arthritis fibroblast-like synoviocytes. AB - In this study, we aimed to explore the effects of imatinib on the proliferation of rheumatoid arthritis synovial cell (RA-FLS) and inflammatory responses by regulating CSF1R. Differential genes were screened via microarray analysis, followed by being analysed through the weighted co-expression network (WGCNA) network, that included module and cluster analysis. The relationship between imatinib and genes was visualized using the Search Tool for the Retrieval of Interacting Genes (STITCH) database. Expressions of mRNA and protein were determined by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot, respectively. Cell viability was examined via clone formation assay, while cell cycle and apoptosis were analysed through flow cytometry analysis. The hub gene CSF1R was ultimately determined by microarray analysis and WGCNA analysis. Colony-stimulating-factor receptor-1 (SF1R) was highly expressed in rheumatoid arthritis tissues and cells, and CSF1R over-expression could promote inflammatory responses. Moreover, CSF1R could promote RA-FLS proliferation, inhibit apoptosis and accelerate the cell cycle. The targeting relationship between imatinib and CSF1R was also validated in this study. Imatinib attenuated RA-FLS inflammation in a concentration-dependent manner. Meanwhile, imatinib could inhibit RA-FLS proliferation and promote apoptosis, ultimately reducing the damage of RA-FLS. Over-expression of CSF1R accelerated the cell cycle and proliferation of RA-FLS, while inhibiting cell apoptosis. Conversely, imatinib could significantly restrain the cell cycle and viability of RA-FLS and accelerated apoptosis via suppression of CSF1R expression. Further, histological and serological assay investigated and proved the proinflammatory effects of CSF1R in RA rabbits. PMID- 30281781 TI - Atrial Fibrillation: Possible Influences of Rate and Rhythm Control Strategy on Cognitive Performance. AB - OBJECTIVES: To determine whether rate or rhythm control strategy may affect cognition in older adults with atrial fibrillation (AF). DESIGN: Retrospective analysis of the REgistro POliterapie SIMI database. SETTING: Italian internal medicine and geriatric wards. PARTICIPANTS: Individuals aged 65 and older (N=1,082, mean age 80.6 +/- 7; 50% male) with AF before hospital admission (for any cause). MEASUREMENTS: Evaluation of cognitive performance using the Short Blessed Test (SBT) according to rhythm and rate control strategy, anticoagulant and antiplatelet therapy, age, education, and comorbidities. RESULTS: Two hundred seventy-two participants (25%) received rhythm control therapy, 331 (30.6%) rate control therapy, and 479 (44.3%) no therapy of interest. Four hundred thirty-six (40.3%) in the total sample and in the different rhythm and rate control strategy groups were treated with an oral anticoagulant. Cognitive performance (mean SBT score) was found to be higher in the rhythm control group (7.5 +/- 6.6) than in the no therapy (9.9 +/- 7.9) and rate control (10.6 +/- 8.3) (p<.001) groups. Logistic regression models adjusted for age, sex, education, anticoagulant and antiplatelet therapy, and comorbidities found that the rhythm control strategy (adjusted odds ratio (aOR)=0.56, 95% confidence interval (CI)=0.40-0.79, p=.001) and education (aOR 0.50, 95% CI=0.35-0.62; p<.001) were associated with less likelihood of cognitive impairment CONCLUSION: In the absence of anticoagulation, rhythm control of AF may protect against cognitive decline.

PMID- 30281783 TI - Effect of Site-Neutral Payment Policy on Long-Term Acute Care Hospital Use. AB - OBJECTIVE: To assess the projected effect of the Centers for Medicare and Medicaid Services new site-neutral payment policy, which aims to decrease unnecessary long-term acute care hospital (LTACH) admissions by reducing reimbursements for less-ill individuals by 2020. DESIGN: Observational. SETTING: National 5% Medicare data (2011-12). MEASUREMENTS: We examined the proportion of site-neutral LTACH admissions. Regional LTACH market supply was defined as LTACH beds per 100,000 residents, categorized according to tertile. We conducted a hospital-level analysis to compare the projected effect of site-neutral payment on "propensity score" matched high- and low-LTACH-use hospitals. RESULTS: Forty one percent of LTACH admissions would be subjected to site-neutral payment. The proportion of site-neutral admissions was large, varied considerably according to LTACH (median 40%, interquartile range 22-60%), and was only modestly greater with greater market supply (Pearson correlation coefficient=0.23, p<.001; coefficient of determination=0.10). The site-neutral payment policy would affect 47% of admissions from the highest-supply regions, versus 30% from the lowest supply regions (p<.001); and 43% from high-use hospitals versus 36% from propensity score-matched low-use hospitals (p<.001). CONCLUSION: A considerable proportion of LTACH admissions will be subjected to lower site-neutral payments. Although the policy will disproportionately affect high-use regions and hospitals, it will also affect nearly one-third of the current LTACH population from low-use hospitals and regions. As such, the site-neutral payment policy may limit LTACH access in existing LTAC-scarce markets, with potential adverse implications for recovery of hospitalized older adults.

AB - In the zebrafish segmentation clock, hairy/enhancer of split-related genes her1, her7, and hes6 encodes components of core oscillators. Since the expression of cyclic genes proceeds rapidly in the presomitic mesoderm (PSM), these hairy related mRNAs are subject to strict post-transcriptional regulation. In this study, we demonstrate that inhibition of the CCR4-NOT deadenylase complex lengthens poly(A) tails of hairy-related mRNAs and increases the amount of these mRNAs, which is accompanied by defective somite segmentation. In transgenic embryos, we show that EGFP mRNAs with 3'UTRs of hairy-related genes exhibit turnover similar to endogenous mRNAs. Our results suggest that turnover rates of her1, her7, and hes6 mRNAs are differently regulated by the CCR4-NOT deadenylase complex possibly through their 3'UTRs in the zebrafish PSM. PMID- 30281785 TI - Disturbed processing of the carbohydrate-binding module of family 54 significantly impairs its binding to polysaccharides. AB - Carbohydrate-binding modules of the family 54 (CBM54) are characterized by spontaneous rupture of the peptide bond Asn266-Ser267 (numbering corresponds to that of laminarinase Lic16A of Ruminiclostridium thermocellum). As a result of processing, two parts are formed noncovalently connected to each other. Here, to gain insights into the functional significance of the internal cleavage, we made modifications of the family-conserved processing site in CBM54 of Lic16A. We demonstrate that the introduced mutations of residues G264 or S267 to alanine block the hydrolysis. Unprocessed, modified proteins bind insoluble polysaccharides pustulan, chitin, xylan, Avicel, phosphoric acid-swollen cellulose, and beta-d-glucan of the yeast cell wall 2-20 times worse than the wild-type module. The data obtained are the first to demonstrate that processing is important for the functioning of CBM54s. PMID- 30281786 TI - Can plants evolve to meet a changing climate?

AB - OBJECTIVES: Despite subsisting on a low-cariogenic diet comprising virtually nothing more than potatoes and dairy products, poor oral health affected the quality of life for the poor of nineteenth-century Ireland. This study investigates potential biocultural reasons that may explain why this was the case. MATERIAL AND METHODS: A total of 6,860 teeth and 9,889 alveoli from 363 permanent dentitions from the skeletal remains of impoverished adult Irish males and females who died between 1847 and 1851 in the Kilkenny Union Workhouse were examined for evidence of dental caries, periodontal disease and ante-mortem tooth loss. Caries rates were quantified and assessed by crude prevalence, frequencies, corrected caries rates and a t-health index, and evaluated by sex and age groups. RESULTS: A higher rate of caries was present among 18-25-year-old males than females, while the opposite relationship was evident for older age groups. The prevalence rates of periodontal disease and ante-mortem tooth loss increased with age. When assessed by corrected caries rates, tooth decay is observed at a lower rate compared to contemporaneous lower to upper-class population samples from London. DISCUSSION: Despite being low cariogenic foods, the potato starch and milk lactose of a nineteenth-century Irish laborer's diet would have lowered oral pH-values thereby increasing the risk of bacterial fermentation in dental plaque resulting in caries. Nutritional features alone cannot explain the high rates of dental caries observed in the Kilkenny workhouse population sample, however, and lifestyle factors, particularly habitual clay-pipe smoking, is considered a significant cause of poor oral health.

AB - We have tested a multiplex polymerase chain reaction (PCR) human papillomavirus (HPV) genotyping assay to fill the need for rapid and low-cost HPV detection in Sub-Saharan Africa. This method allows high throughput genotyping and simultaneous detection of 14 high-risk and two low-risk HPV types, by PCR amplification of HPV DNAs in a single reaction tube. In this study, we describe stepwise experiments to validate the multiplex HPV PCR assay for determination of HPV genotypes from 104 cervical brush samples from Tanzanian women. Assay performance was evaluated by determination of intra-laboratory reproducibility, sensitivity, and specificity. Further performance was assessed by comparison with the widely accepted and validated HPV My09/My11 amplification and hybridization assay. Statistics; the Cohen kappa (kappa) and McNemar P values were used to analyze interobserver and intermethod agreement. Overall concordance between the multiplex and line blot hybridization assays was 99% (per sample) with a kappa value equal to 0.95; and 96.49% (per detection event) with a kappa value of 0.92. Interobserver reproducibility of the assay per sample was 95.76% with kappa of 0.91. These results demonstrate that the multiplex HPV PCR assay has high analytical sensitivity and specificity in detecting as many as 16 different HPV genotypes and that its simplicity and low cost makes it well suited for sub Saharan Africa.

Results were related to ecosystem fertility (soil inorganic N, pH and litter C : N). Root-derived C was estimated to decompose two to 10 times more slowly than leaf litter, but more rapidly in fertile plots. The amounts of C and N per cohort declined during the initial 20 yr of decomposition, but, in older material, the amount of N per cohort increased, indicating N retention driven by root-derived C. The dynamics of root-derived inputs were more important than leaf litter dynamics in regulating the variation in organic matter accumulation along a forest fertility gradient. N retention in the rooting zone combined with impeded mining for N in less fertile ecosystems provides evidence for a positive feedback between ecosystem fertility and organic matter turnover. PMID- 30281793 TI - Role of the tightly bound quinone for the oxygen reaction of cytochrome bo3 oxidase from Escherichia coli. AB - The coupling of the reaction of a tightly bound ubiquinone with the reduction of O2 in cytochrome bo3 of Escherichia coli was investigated. In the absence of the quinone, a strongly diminished rate of electrocatalytic reduction of oxygen is detected, which can be restored by adding quinones. The correlation of previous EPR data with the electrocatalytic study on mutations in the binding site at positions, Q101, D75, F93, H98, I102 and R71 reveal that the stabilization of the radical is not necessary for the oxygen reaction. The Q101 and F93 variants exhibit both well-defined catalytic i-V curves, whereas D75H, H98F, I102W and R71H exhibit broad i-V curves with large hysteresis pointing toward a strong alteration in their catalytic activity. PMID- 30281794 TI - Development of a Clinically Feasible Process for Identifying Individual Health Priorities. AB - OBJECTIVES: To develop a values-based, clinically feasible process to help older adults identify health priorities that can guide clinical decision-making. DESIGN: Prospective development and feasibility study. SETTING: Primary care practice in Connecticut. PARTICIPANTS: Older adults with 3 or more conditions or taking 10 or more medications (N=64). INTERVENTION: The development team of patients, caregivers, and clinicians used a user-centered design framework-ideate -> prototype -> test ->redesign-to develop and refine the value-based patient priorities care process and medical record template with trained clinician facilitators. MEASUREMENTS: We used descriptive statistics of quantitative measures (percentage accepted invitation and completed template, duration of process) and qualitative analysis of barriers and enablers (challenges and solutions identified, facilitator perceptions). RESULTS: We developed and refined a process for identifying patient health priorities that was typically completed in 35 to 45 minutes over 2 sessions; 64 patients completed the process. Qualitative analyses were used to elucidate the characteristics and training needed for the patient priorities facilitators, as well as perceived benefits and challenges of the process. Refinements based on our experience and feedback include streamlining the process for greater feasibility, balancing fidelity to the process while customizing to individuals, encouraging patients to share their priorities with their clinicians, and simplifying the template transmitted to clinicians. CONCLUSION: Trained facilitators conducted this process in a busy primary care practice, suggesting that patient priorities identification is feasible and acceptable, although testing in additional settings is necessary. We hope to show that clinicians can align care with patients' health priorities.

AB - KEY POINTS: In rodents, including mice, the superior colliculus is the major target of the retina, but its visual response is not well characterized. In the present study, extracellular recordings from single nerve cells in the superficial layers of the superior colliculus were made in awake, head-restrained mice, and their responses to visual stimuli were measured. It was found that these neurons show brisk, highly sensitive and short latency visual responses, a preference for black over white stimuli, and diverse responses to moving patterns. At least five broad classes can be defined by variation in functional properties among units. The results of the present study demonstrate that eye movements have a measurable impact on visual responses in awake animals and show how they may be mitigated in analyses. ABSTRACT: The mouse is an increasingly important animal model of visual function in health and disease. In mice, most retinal signals are routed through the superficial layers of the midbrain superior colliculus, and it is well established that much of the visual behaviour of mice relies on activity in the superior colliculus. The functional organization of visual signals in the mouse superior colliculus is, however, not well established in awake animals. We therefore made extracellular recordings from the superficial layers of the superior colliculus in awake mice, while the animals were viewing visual stimuli including flashed spots and drifting gratings. We find that neurons in the superficial layers of the superior colliculus of awake mouse generally show short latency, brisk responses. Receptive fields are usually 'ON-OFF' with a preference for black stimuli, and are weakly non-linear in response to gratings and other forms of luminance modulation. Population responses to drifting gratings are highly contrast sensitive, with a robust response to spatial frequencies above 0.3 cycles degree 1 and temporal frequencies above 15 Hz. The receptive fields are also often speed tuned or direction-selective. Analysis of the response across multiple stimulus dimensions reveals at least five functionally distinct groups of units. We also find that eye movements affect measurements of receptive field properties in awake animals, and show how these may be mitigated in analyses. Qualitatively similar responses were obtained in urethane-anaesthetized animals, although receptive fields in awake animals had higher contrast sensitivity, shorter visual latency and a stronger response to high temporal frequencies. PMID- 30281797 TI - The central amygdala to periaqueductal gray pathway comprises intrinsically distinct neurons differentially affected in a model of inflammatory pain. AB - KEY POINTS: The central nucleus of the amygdala (CeA) encompasses the main output pathways of the amygdala, a temporal lobe structure essential in affective and cognitive dimensions of pain. A major population of neurons in the CeA send projections to the periaqueductal gray (PAG), a key midbrain structure that mediates coping strategies in response to threat or stress. CeA-PAG neurons are topographically organized based on their targeted subregion within the PAG. PAG projecting neurons in the central medial (CeM) and central lateral (CeL) regions of CeA are intrinsically distinct. CeL-PAG neurons are a homogeneous population of intrinsically distinct neurons while CeM-PAG neurons are intrinsically heterogeneous. Membrane properties of distinct CeM-PAG subtypes are altered in the complete Freund's adjuvant model of inflammatory pain. ABSTRACT: A major population of neurons in the central nucleus of amygdala (CeA) send projections to the periaqueductal gray (PAG), a key midbrain structure that mediates coping strategies in response to threat or stress. While the CeA-PAG pathway has proved to be a component of descending anti-nociceptive circuitry, the functional organization of CeA-PAG neurons remains unclear. We identified CeA-PAG neurons in C57BL/6 mice of both sexes using intracranial injection of a fluorescent retrograde tracer into the PAG. In acute brain slices, we investigated the topographical and intrinsic characteristics of retrogradely labelled CeA-PAG neurons using epifluorescence and whole-cell electrophysiology. We also measured changes to CeA-PAG neurons in the complete Freund's adjuvant (CFA) model of inflammatory pain. Neurons in the central lateral (CeL) and central medial (CeM) amygdala project primarily to different regions of the PAG. CeL-PAG neurons consist of a relatively homogeneous population of intrinsically distinct neurons while CeM-PAG neurons are intrinsically heterogeneous. Membrane properties of distinct CeM-PAG subtypes are altered 1 day after induction of the CFA inflammatory pain model. Collectively, our results provide insight into pain induced changes to a specific population of CeA neurons that probably play a key role in the integration of noxious input with endogenous analgesia and behavioural coping response. PMID- 30281796 TI - Self-Reported Physical Function As a Predictor of Hospitalization in the Lifestyle Interventions and Independence for Elders Study. AB - OBJECTIVES: To explore whether baseline scores on the Mobility Assessment Tool short form (MAT-sf), a brief, animated, computer-based means of assessing mobility that predicts mobility disability, are associated with number of hospitalizations and time to first hospitalization over a median follow-up of 2.7 years. DESIGN: Post hoc analysis of prospectively gathered data from the Lifestyle Interventions and Independence for Elders (LIFE) Study, a randomized clinical trial of lifestyle interventions to preserve mobility in older adults. SETTING: Eight U.S. academic medical centers. PARTICIPANTS: Of 1,635 sedentary community-dwelling older adults enrolled in LIFE, 1,574 completed baseline physical function screening including the MAT-sf, with baseline scores ranging from 30.2 (low function) to 69.8 (high function) on a scale from 30 to 80. MEASUREMENTS: Number of hospitalizations and time to first hospitalization, adjusted for age, sex, race, living alone, clinical site, baseline comorbidities, number of prescription medications, and cognition. RESULTS: Of the 1,557 participants with data regarding hospitalization status, 726 (47%) had at least 1 hospitalization; 78% of these had 1 or 2 hospitalizations. For every 10-point lower MAT-sf score, the rate of all hospitalizations was 19% higher in those with lower scores (adjusted rate ratio=1.20, 95% confidence interval (CI)=1.08-1.32, p<.001). Lower baseline MAT-sf scores were also associated with greater risk of first hospitalization (adjusted hazard ratio=1.20, 95% CI=1.09-1.32, p<.01, per 10-point lower MAT-sf score). CONCLUSION: Low MAT-sf scores identify older adults at risk of hospitalization; further study is needed to test interventions to reduce hospitalizations in these individuals. PMID- 30281799 TI - Cold sensitivity of mitochondrial ATP synthase restricts oxidative phosphorylation in Arabidopsis thaliana. AB - The combined action of the electron transport chain (ETC) and ATP synthase is essential in determining energy efficiency in plants, and so is important for cellular biosynthesis, growth and development. Owing to the sessile nature of plants, mitochondria must operate over a wide temperature range in the environment, necessitating a broad temperature tolerance of their biochemical reactions. We investigated the temperature response of mitochondrial respiratory processes in isolated mitochondria and intact plants of Arabidopsis thaliana and considered the effect of instantaneous responses to temperature and acclimation responses to low temperatures. We show that at 4 degrees C the plant mitochondrial ATP synthase is differentially inhibited compared with other elements of the respiratory pathway, leading to decreased ADP : oxygen ratios and a limitation to the rate of ATP synthesis. This effect persists in vivo and cannot be overcome by cold-temperature acclimation of plants. This mechanism adds a new element to the respiratory acclimation model and provides a direct means of temperature perception by plant mitochondria. This also provides an alternative explanation for non-phosphorylating ETC bypass mechanisms, like the alternative oxidase to maintain respiratory rates, albeit at lower ATP synthesis efficiency, in response to the sensitivity of ATP synthase to the prevailing temperature. PMID- 30281798 TI - Of puzzles and pavements: a quantitative exploration of leaf epidermal cell shape. AB - Epidermal cells of leaves are diverse: tabular pavement cells, trichomes, and stomatal complexes. Pavement cells from the monocot Zea mays (maize) and the eudicot Arabidopsis thaliana (Arabidopsis) have highly undulate anticlinal walls. The molecular basis for generating these undulating margins has been extensively investigated in these species. This has led to two assumptions: first, that particular plant lineages are characterized by particular pavement cell shapes; and second, that undulatory cell shapes are common enough to be model shapes. To test these assumptions, we quantified pavement cell shape in epidermides from the leaves of 278 vascular plant taxa. We found that monocot pavement cells tended to have weakly undulating margins, fern cells had strongly undulating margins, and eudicot cells showed no particular undulation degree. Cells with highly undulating margins, like those of Arabidopsis and maize, were in the minority. We also found a trend towards more undulating cell margins on abaxial leaf surfaces; and that highly elongated leaves in ferns, monocots and gymnosperms tended to have highly elongated cells. Our results reveal the diversity of pavement cell shapes, and lays the quantitative groundwork for testing hypotheses about pavement cell form and function within a phylogenetic context. PMID- 30281800 TI - Photobiomodulation Affects Key Cellular Pathways of all Life-Forms: Considerations on Old and New Laser Light Targets and the Calcium Issue. AB - After 50 years of studies on photobiomodulation (PBM), there is still so much to investigate to understand the laser light-nonplant cells interactions. The current scientific knowledge allows to say that the phenomena induced by PBM are based on cellular pathways that are the key points of cell life. The mitochondria chromophores, also present on the bacterial membrane, the calcium channels, ion that regulates the life-and-death cellular processes, as well as the TRP family, whose genes have been found in protozoa and suggest that its basic mechanism evolved long before the appearance of animals, seem to be elective targets in photobiomodulatory events by wavelengths from 600 up to 980 nm. The ambiguous resulting cellular communication way, mediated by ATP, ROS and/or calcium, leads to cell manipulation, which modifies its metabolism and whose response connects all life-forms from bacteria to vertebrates. Because of the Giano-Bifronte features of ROS and calcium, as well as the fine balance of energetic mitochondrial processes, whose alteration is responsible for several diseases, the PBM can show unpredictable results and it requires scrupulous approach to avoid cellular damages. However, when carefully applied, PBM is able to improve nonhealthy cell's responses and represents a reliable support in human and veterinary medicine. PMID- 30281801 TI - Functional trait divergence and trait plasticity confer polyploid advantage in heterogeneous environments. AB - Polyploidy, or whole-genome duplication often with hybridization, is common in eukaryotes and is thought to drive ecological and evolutionary success, especially in plants. The mechanisms of polyploid success in ecologically relevant contexts, however, remain largely unknown. We conducted an extensive test of functional trait divergence and plasticity in conferring polyploid fitness advantage in heterogeneous environments, by growing clonal replicates of a worldwide genotype collection of six allopolyploid and five diploid wild strawberry (Fragaria) taxa in three climatically different common gardens. Among leaf functional traits, we detected divergence in trait means but not plasticities between polyploids and diploids, suggesting that increased genomic redundancy in polyploids does not necessarily translate into greater trait plasticity in response to environmental change. Across the heterogeneous garden environments, however, polyploids exhibited fitness advantage, which was conferred by both trait means and adaptive trait plasticities, supporting a 'jack and-master' hypothesis for polyploids. Our findings elucidate essential ecological mechanisms underlying polyploid adaptation to heterogeneous environments, and provide an important insight into the prevalence and persistence of polyploid plants.

AB - The goal of this review was to identify and discuss the specialized methods that have been used to assess the corneas of the eyes of living rabbits exposed to the damaging effects of ultraviolet-B (UV-B). From publications reviewed between 1916 and 2018, both albino and pigmented rabbits were used, usually being young adults weighing between 2 and 2.5 kg, and with many recent studies carried out under sedation. Older assessments were generally based on the use of in vivo slitlamp examinations, sometimes with the use of fluorescein or rose bengal to identify damaged cells, supported by light microscopy (histology) of excised corneas. In later years (after 1960), these structural studies have included in vivo and ex vivo specular microscopy, transmission and scanning electron microscopy as well as impression cytology. Early studies included measurements of the thickness of excised corneal specimens but in vivo pachymetry methods were widely used from the 1980s. Other assessments have included measurement of light transmission spectra of excised corneas, measures of metabolites in isolated corneas or staining corneal specimens for enzyme activities. While a wide range of specialized methods have been used, most of them have provided only descriptions of the effects of UV-B. PMID- 30281804 TI - Nicotinamide nucleotide transhydrogenase is required for brain mitochondrial redox balance under hampered energy substrate metabolism and high-fat diet. AB - Among mitochondrial NADP-reducing enzymes, nicotinamide nucleotide transhydrogenase (NNT) establishes an elevated matrix NADPH/NADP+ by catalyzing the reduction of NADP+ at the expense of NADH oxidation coupled to inward proton translocation across the inner mitochondrial membrane. Here, we characterize NNT activity and mitochondrial redox balance in the brain using a congenic mouse model carrying the mutated Nnt gene from the C57BL/6J strain. The absence of NNT activity resulted in lower total NADPH sources activity in the brain mitochondria of young mice, an effect that was partially compensated in aged mice. Nonsynaptic mitochondria showed higher NNT activity than synaptic mitochondria. In the absence of NNT, an increased release of H2 O2 from mitochondria was observed when the metabolism of respiratory substrates occurred with restricted flux through relevant mitochondrial NADPH sources or when respiratory complex I was inhibited. In accordance, mitochondria from Nnt-/- brains were unable to sustain NADP in its reduced state when energized in the absence of carbon substrates, an effect aggravated after H2 O2 bolus metabolism. These data indicate that the lack of NNT in brain mitochondria impairs peroxide detoxification, but peroxide detoxification can be partially counterbalanced by concurrent NADPH sources depending on substrate availability. Notably, only brain mitochondria from Nnt-/- mice chronically fed a high-fat diet exhibited lower activity of the redox sensitive aconitase, suggesting that brain mitochondrial redox balance requires NNT under the metabolic stress of a high-fat diet. Overall, the role of NNT in the brain mitochondria redox balance especially comes into play under mitochondrial respiratory defects or high-fat diet. PMID- 30281805 TI - Impact of route of administration on genotoxic oestrogens concentrations using oral vs transdermal oestradiol in girls with Turner syndrome. AB - OBJECTIVE: The established link between oestrogen and breast cancer occurs via both oestrogen receptor (ER)-mediated and non ER-mediated mechanisms. The term genotoxic estrogens describes mutagenic metabolites, including oestrogen catechols and quinones, which have been linked to breast carcinogenesis in post menopausal women. We aimed to assess whether the route of administration of 17beta oestradiol (E2 ) affects the accumulation of genotoxic oestrogen metabolites in a model of ovarian failure in young girls with Turner syndrome. METHODS: Stored plasma samples obtained at 0 and 12 months were used from 40 adolescents with Turner syndrome who participated in a 12 months randomized controlled trial of the metabolic impact of E2 orally (2 mg/d) vs transdermally (100 ug/d); dose escalation allowed matching of unconjugated E2 levels in the parent study. We measured 12 oestrogen metabolites (total concentrations = conjugated and unconjugated) using a highly sensitive LCMSMS assay. Results from 48 normally menstruating adolescents were used for comparison. RESULTS: After treatment, least square mean (SE) total E2 concentrations were higher in the oral vs transdermal group (6784 pmol/L vs 1123 [1614], P < 0.0001), as was oestrone (E1 ) (91 060 pmol/L vs 19 278 [16 534], P < 0.0001). Also, higher after oral treatment were catechol-oestrogens 4-hydroxy-E2 (149 vs 28 [+/-49] pmol/L), 2 hydroxy-E2 (300 vs 76 [+/-52]), 4-hydroxy-E1 (450 vs 105 [+/-113]), 2-hydroxy-E1 (3094 vs 740 [+/-684]) and 16alpha-hydroxy-E1 (3,007 vs 157 [+/-534]) (<0.001 between groups). Levels were much closer to controls in the transdermal group. CONCLUSIONS: Common feminizing doses of oral oestradiol for 12 months result in substantial accumulation of unphysiologic, genotoxic oestrogens compared to transdermal oestradiol, expanding concerns about oral oestrogens' first hepatic passage. Further studies assessing long-term risks of these metabolites in women taking different forms of oestrogen are needed. PMID- 30281806 TI - Deceased Pediatric Donor Livers: How Current Policy Drives Allocation and Transplantation. AB - BACKGROUND AND AIMS: Each year, approximately 60 children, representing 12% of waitlist candidates, die awaiting liver transplantation. The current allocation algorithm for pediatric donor livers prioritizes local/regional adults over national children. We attempted to better understand the impact of the present algorithm on pediatric candidates. METHODS: We analyzed pediatric donor liver offers from 2010 to 2014. Donors and recipients were classified based on age. We mapped allocation and acceptance patterns, and used subgroup analyses to explore the significance of Donor Service Areas (DSAs) with low pediatric transplant volumes. We used Cox proportional hazard regressions to evaluate post transplantation outcomes. RESULTS: 3,318 pediatric donor livers were transplanted into 3,482 recipients, 45% (1,569) were adults. Of the 1,569 adults, 25% (390) were received a pediatric organ that was never offered to children. 52% (204) of these 390 pediatric organs originated in the 37 DSAs with <=25 pediatric liver transplantations. 278 children died or were delisted due to illness during the same time with higher mortality rates in the 37 DSAs (10% versus 6%, p<0.01). Compared to adults, pediatric recipients aged <12 years had lower risks of post transplant mortality (HR0.62, 95%CI0.46-0.81, p<0.01). CONCLUSIONS: We found that 45% of pediatric donor livers were transplanted into adults: 390 adults were transplanted with pediatric organs never offered to children access while 278 children died or were delisted due to illness. This was more apparent in DSAs with low pediatric transplant volumes. We advocate for a change to allocation policies to allow pediatric organs to be offered to national children with status 1B or MELD/PELD >15 before being offered to Local/Regional + Circle non-status 1A adults.

PMID- 30281807 TI - Prevalence characteristics of single and multiple HPV infections in women with cervical cancer and precancerous lesions in Beijing, China. AB - We assessed the prevalence characteristics of single and multiple high-risk human papillomavirus (HR-HPV) infections. A total of 1783 women who underwent colposcopy and cervical biopsy for abnormal ThinPrep Cytology Test and/or HR-HPV subtype genotyping results were enrolled in the study. Among the participants, 770 were diagnosed with cervicitis, 395 with cervical intraepithelial neoplasia grade 1 (CIN1), 542 with CIN2-3, and 76 with squamous cell carcinoma (SCC), with HR-HPV infection rates of 75.8%, 85.8%, 95.9%, and 88.4%, respectively. The prevalence of total and multiple HR-HPV infections exhibited a bimodal age distribution with a peak at <=25 years, a decline with age and a second peak at >=55 years, whereas single HR-HPV infections exhibited one peak from 35 to 44 years. The four most dominant HPV genotypes were HPV 16 (29.5%), 52 (15.0%), 58 (14.2%), and 18 (10.4%). In total, 67.0%, 70.4%, and 82.1% of patients with CIN1, CIN2-3, and SCC, respectively, had a single HR-HPV infection, which increased significantly with the aggravation of the cervical lesion grade (P = 0.045). Patients with a single HPV 16 infection had higher incidences of CIN2+ (62.2%) than those with multiple HPV 16 infections (52.4%) (P = 0.021). Patients coinfected with HPV 16 had higher CIN2+ incidence than those with single HPV 52, 31, 33, 35, 39, 45, 51, 56, or 59 infections (P < 0.001). This study provided baseline data on the prevalence characteristics of single and multiple HR-HPV infections in women attending a gynecological outpatient clinic in Beijing. PMID- 30281809 TI - LXRalpha Promotes Hepatosteatosis in Part via Activation of MicroRNA-378 Transcription and Inhibition of Ppargc1beta Expression. AB - : Non-alcoholic fatty liver disease (NAFLD) is a major risk factor of many end stage liver diseases. Alterations in microRNA expression have been reported in NAFLD patients. However, the transcriptional mechanism(s) of dysregulated microRNAs under the state of NAFLD is poorly described; and microRNAs that regulate the pathogenesis of NAFLD synergistically with their regulators remain unknown. Here we report that microRNA-378 expression is significantly increased in fatty livers of mice and NAFLD patients. Although microRNA-378 locates within the intron of Ppargc1beta (Peroxisome proliferator-activated receptor gamma coactivator 1-beta), there was a significant uncoupling of Ppargc1beta mRNA and microRNA-378 levels in both sources of fatty livers. Further studies identified a full-length primary transcript of microRNA-378 (pri-miR-378). LXRalpha (Liver X receptor alpha) functioned as a transcription activator of microRNA-378 and a repressor of Ppargc1beta transcription. It is known that miR-378 is an inhibitor of fatty acid oxidation (FAO) and the function of Ppargc1beta is opposite to that of miR-378. GW3965 treatment (LXRalpha agonist) of murine hepatocytes and mice increased microRNA-378 and reduced Ppargc1beta, which subsequently impaired FAO and aggravated hepatosteatosis; while additional treatment of miR-378 inhibitor or Ppargc1beta, which knocked down increased miR-378 or recovered expression of Ppargc1beta, offset the effects of GW3965. Liver-specific ablation of Lxralpha led to decreased miR-378 and increased Ppargc1beta, which subsequently improved FAO and reduced hepatosteatosis. CONCLUSIONS: our findings indicated that miR-378 possesses its own transcription machinery, which challenges the well-established dogma that miR-378 transcription is controlled by the promoter of Ppargc1beta. LXRalpha selectively activates transcription of miR-378 and inhibits expression of Ppargc1beta, which synergistically impairs FAO. In addition to lipogenesis, impaired FAO by miR-378 in part contributes to LXRalpha-induced hepatosteatosis. This article is protected by copyright. All rights reserved. PMID- 30281808 TI - Group movements in response to competitors' calls indicate conflicts of interest between male and female grey-cheeked mangabeys. AB - Long-distance vocalizations mediate spacing patterns by allowing groups to choose whether to draw close enough to a neighbor to initiate a short-range interaction. It is unclear, however, whether the patterning of calls and the resulting movements are invariant or change in response to social and ecological variables. In this study, we compare the impact of long-distance calls on neighboring groups' movements in two populations of grey-cheeked mangabeys (Lophocebus albigena) in Uganda, which differed widely in group density and food availability. We monitored movement responses of target groups to both naturally occurring and experimentally simulated "whoop-gobble" vocalizations of neighboring adult males to test whether responses indicated mate and food defense. When defending access to fertile females, males might coerce group members to move away from neighboring males; when defending fitness-limiting food resources, however, groups might approach and attempt to evict neighbors. Controlling for pre-call movement prior to the vocalization, we found no difference in group responses between the low- and high-density populations, and little support for either form of defense. Mangabey groups generally continued moving in their original direction, albeit at a slower pace, and deviations from this pattern were predictable: they avoided nearby callers but approached distant callers; they approached if the caller was in the area where home ranges overlapped; and approached when their own group contained multiple peak-estrous females. The effect of multiple fertile females potentially indicates a breakdown of male control as a result of within-group intrasexual mating competition, and greater-than-expected female control over travel movements. As suspected, grey cheeked mangabeys use neighbors' long-distance calls to maintain a spatial buffer between groups but changes in group movements indicate a conflict between male and female interests. PMID- 30281810 TI - One-year change in cognitive flexibility and fine motor function in middle-aged male and female marmosets (Callithrix jacchus). AB - The common marmoset (Callithrix jacchus) is uniquely suited for longitudinal studies of cognitive aging, due to a relatively short lifespan, sophisticated cognitive abilities, and patterns of brain aging that resemble those of humans. We examined cognitive function and fine motor skills in male and female marmosets (mean age ~5 at study entry) followed longitudinally for 2 years. Each year, monkeys were tested on a reversal learning task with three pairs of stimuli (n = 18, 9 females) and a fine motor task requiring them to grasp small rewards from two staircases (Hill and Valley test, n = 12, 6 females). There was little evidence for a decline in cognitive flexibility between the two time points, in part because of practice effects. However, independent of year of testing, females took longer than males to reach criterion in the reversals, indicating impaired cognitive flexibility. Motivation was unlikely to contribute to this effect, as males refused a greater percentage of trials than females in the reversals. With regards to motor function, females were significantly faster than males in the Hill and Valley task. From Year 1 to Year 2, a slight slowing of motor function was observed in both sexes, but accuracy decreased significantly in males only. This study (1) demonstrates that marmosets exhibit sex differences in cognitive flexibility and fine motor function that resemble those described in humans; (2) that changes in fine motor function can already be detected at middle age; and (3) that males may experience greater age-related changes in fine motor skills than females. Additional data points will determine whether these sex and age differences persist over time. PMID- 30281811 TI - Reduction in a high-risk sex script among young urban women in the Love, Sex, & Choices web video HIV prevention intervention study. AB - For women, the high-risk sex script of condomless sex to maintain relationships with men is concerning, particularly in regard to heterosexual HIV acquisition. This secondary analysis of data from a clinical trial evaluated the effect of a 12-episode, web-based video series intervention, entitled Love, Sex, and Choices, versus a text message control on lowering the high-risk sex script. The sample comprised 238 predominately urban Black women, ages 18-29, having HIV sex risk behavior. Data were collected at baseline and 6 months post-intervention. The Sex Script Video Response score was used to measure a high-risk sex script. HIV sex risk behavior was measured by Vaginal Equivalent Episodes with high-risk partners. At baseline, lower education, younger age at first sexual intercourse, and alcohol/non-injection drug use before sex were positively associated with a high-risk sex script. At baseline, as the high-risk sex script increased by one log unit, sex risk behavior increased by 0.47 log units (p < 0.001), equivalent to a 60% increase in the geometric mean of sex risk behavior. ANCOVA analysis indicated that from baseline to 6-months post intervention, lowering the high risk sex script by one unit was associated with an additional reduction of 0.26 units in sex risk behavior. Compared to the text messages, the LSC video series was associated with a 27% greater reduction in the geometric mean of the sex script (p = 0.03). Further investigation into the effect of lowering sex scripts to reduce sex risk behavior is recommended. PMID- 30281812 TI - Full ablative versus fractional ablative laser therapy for Dowling-Degos disease. AB - Dowling-Degos disease (DDD) is a rare autosomal-dominant genodermatosis with limited treatment possibilities. Although the efficacy of ablative laser therapy has been reported, we sought to examine the efficacy of fractional versus full ablative laser therapy in a female patient with DDD in a split-side report. We treated the lesions on the right side of the patient's upper abdomen with an ablative fractional CO2 laser and the lesions on the left side of the upper abdomen with a full ablative Er:YAG laser (erbium-doped yttrium aluminium garnet laser) three times at monthly intervals. After three laser sessions, the lesions treated with the Er:YAG laser showed a complete response, whereas the fractional CO2 laser treatment was less effective. After the three treatments were performed, the right side of the patient's upper abdomen and portions of her lower abdomen and chest were also treated with the Er:YAG laser in full ablation mode with the same settings. After 1 year of follow up, there was no recurrence observed. Lasers Surg. Med. (c) 2018 Wiley Periodicals, Inc. PMID- 30281813 TI - Optimal frequency of tooth brushing in mechanically ventilated adults: Study protocol for a randomized controlled trial. AB - The optimal frequency of tooth brushing in the critically ill has not been experimentally determined. For mechanically ventilated patients, optimal frequency of tooth brushing is an important unresolved issue as there is little evidence to judge the benefits or associated risks of tooth brushing. Given this knowledge gap, the project's overall goal is to determine the optimal frequency of tooth brushing (once, twice, or three times daily) for mechanically ventilated adults. A prospective, randomized, experimental design is used. Specifically, 345 subjects, with 207 expected to complete the study, are randomly assigned within 36 hr of intubation to one of three groups (once, twice, or three times tooth brushing daily). Tooth brushing with a soft compact-head toothbrush takes approximately 2 min. Dental plaque assessment, gingival crevicular fluid (GCF) determination for IL-1beta, and data regarding healthcare-acquired infection (HAI) and clinical status are collected at baseline and daily in-hospital. The clinical impact of daily frequency of tooth brushing in relation to extent of dental plaque and inflammation reflected by GCF analysis will be compared by the three treatment arms. In addition, evaluation of safety for HAIs will be compared based on calculation of the number needed to harm. The trial will empirically determine the optimal frequency of tooth brushing in mechanically ventilated adults, balancing benefits and risks. This contribution is significant because it will have immediate impact on bedside nursing practice, and is a final component necessary for specific evidence-based guidelines for the common nursing intervention of oral care in mechanically ventilated adults. PMID- 30281814 TI - Oxytocin, vasopressin, and primate behavior: Diversity and insight. AB - It has become increasingly clear that the nonapeptide hormones oxytocin and vasopressin have more diverse behavioral and physiological effects across species and across individuals than was initially recognized. To reflect this variation, we would like to introduce our Special Issue, entitled Oxytocin and Vasopressin in Primate Behavior, by celebrating the diversity that is found across the articles within it. While every article directly addresses the topic of this Special Issue, they also vary in many characteristics: the species studied, the methods used, and the perspectives taken. By highlighting the interesting ways in which these articles differ from one another, we can gain unique insights into the subject that ties them together: our understanding of oxytocin and vasopressin and the behavior of primates. Nonhuman primates are critical intermediates between rodents and humans and are the best models for human biology and behavior, especially with respect to complex cognitive social constructs, such as visual social attention, face processing, and vocal communication. While rodent studies have laid an important and foundational framework for our understanding of nonapeptides, brains, and behavior, these studies cannot fully recapitulate human phenomena. Therefore, we hope the articles presented here contribute to a greater understanding on the role of oxytocin and vasopressin in primate physiology and behavior and help to further advance the application of this knowledge to human biology. PMID- 30281815 TI - DEAD Box Protein 5 Inhibits Liver Tumorigenesis by Stimulating Autophagy via Interaction with p62/SQSTM1. AB - : In hepatocellular carcinoma (HCC), dysregulated expression of DDX5 (DEAD box protein 5) and impaired autophagy have been reported separately. However, the relationship between them has not been explored. Here we present evidence to show that, by interacting with autophagic receptor p62, DDX5 promotes autophagy and suppresses tumorigenesis. DDX5 inversely correlated with p62/sequestosome 1 (SQSTM1) expression in HBV-associated and non-HBV associated HCCs. Patients with low DDX5 expression showed poor prognosis after tumor resection. We found that DDX5 overexpression induced, while DDX5 knockdown attenuated autophagic flux in HepG2 and Huh7 cells. DDX5 promoted p62 degradation and markedly reduced the half life of p62. Moreover, DDX5 overexpression dramatically reduced while DDX5 knockdown promoted cancer cell growth and tumorigenesis in vitro and in vivo. We found that DDX5 bound to p62 and interfered with p62/TRAF6 (TNF receptor associated factor 6) interaction. Further findings revealed that the N-terminal domain of DDX5, involved in the interaction with p62, was sufficient to induce autophagy independent of its RNA binding and helicase activity. DDX5 overexpression decreased p62/TRAF6 mediated lysine 63-linked ubiquitination of mTOR, and subsequently inhibited the mTOR signaling pathway. Knockdown of TRAF6 blocked DDX5-induced autophagy. Furthermore, we showed that the miR-17-5p downregulated DDX5 and impaired autophagy. Inhibition of miR-17-5p promoted autophagic flux and suppressed tumor growth in HCC xenograft models. CONCLUSION: Our findings define a non-canonical pathway that links miR-17-5p, DDX5, p62/TRAF6, autophagy and HCC. These findings open a new avenue for the treatment of HCC.

AB - We read with interest the paper by Arora et al. comparing terlipressin with noradrenaline in the management of acute kidney injury (AKI) in patients with acute-on-chronic liver failure (ACLF). The authors designed a randomized controlled trial to compare the response to therapy, course and outcomes between the two drugs. We agree with most of their observations, but we would like some more clarity regarding their conclusions. This article is protected by copyright. All rights reserved. PMID- 30281817 TI - Scars on plants sourced for termite fishing tools by chimpanzees: Towards an archaeology of the perishable. AB - Chimpanzees are well-studied, but raw material acquisition for tool use is still poorly understood as sources are difficult to trace. This study pioneers the use of information that can be gleaned from plant scars made by chimpanzees while they source vegetation parts to manufacture termite fishing tools. Source plant species, raw material types and locations relative to targeted termite mounds were recorded for populations at Gombe, Issa, and Mahale in western Tanzania. Recovered bark, twig, and vine tools were traced to 29 plant species, while grass sources were indeterminable. Bark extraction scars remained detectable for months, and thus possibly for as long as the plant is alive, while twig and vine scars preserved for a few weeks only. Scars preserve better than tools, given that twice as many plant species could be linked to the former than to the latter. Some source species were exploited across all sites for the same type of tool material, while two species were sourced for different types. Compared to apes at Gombe and Mahale, Issa chimpanzees carried material from twice as far away, perhaps because the Issa habitat is more open and dry, which entails greater distances between suitable raw material sources and targeted mounds. Site specific tools were based on different raw materials, in two cases sourced from the same species, which could suggest learned preferences for particular tool material. "Archaeology of the perishable" as pioneered in this study broadens the methodological approach of the wider field of primate archaeology to include reconstructions of past animal behavior associated with the production of plant based tools.

AB - Self-management among adolescents with type 1 diabetes (T1D) is poorer than in other age groups during childhood. A valid and reliable short-form scale to measure self-management in adolescents with T1D is prudent for enhancing their self-management in clinical settings. We used a cross-sectional design to develop a short-form Chinese version of the Self-Management of Type 1 Diabetes for Adolescents Scale (C-SMOD-A) and test its psychometric characteristics. Two hundred adolescents with T1D were recruited from four hospitals in Taiwan through convenience sampling. Content validity, exploratory factor analysis, and corrected item-total correlations were used to shorten the 52-item C-SMOD-A. Confirmatory factor analysis, criterion-related validity, and reliability testing were used to examine the psychometric characteristics of the short-form C-SMOD-A. Finally, the 23-item C-SMOD-A (C-SMOD-A-23) with five inter-correlated factors was developed. Glycated hemoglobin levels were significantly associated with each subscale of the C-SMOD-A-23 with correlation coefficients ranging from -0.18 to 0.31. The composite reliability and test-retest reliability of the five subscales ranged from 0.70 to 0.88 and from 0.78 to 0.93 respectively. Accordingly, the C SMOD-A-23 has acceptable validity and reliability to measure five specific domains of self-management for adolescents with T1D. Health-care providers could use the C-SMOD-A-23 as a clinical reference to assess specific domains of self management and provide interventions to enhance self-management for adolescents with T1D. PMID- 30281819 TI - A computational method to characterize the missense mutations in the catalytic domain of GAA protein causing Pompe disease. AB - Pompe disease is an autosomal recessive lysosomal storage disease caused by acid alpha-glucosidase (GAA) deficiency, resulting in intralysosomal accumulation of glycogen, including cardiac, skeletal, and smooth muscle cells. The GAA gene is located on chromosome 17 (17q25.3), the GAA protein consists of 952 amino acids; of which 378 amino acids (347-726) falls within the catalytic domain of the protein and comprises of active sites (518 and 521) and binding sites (404, 600, 616, and 674). In this study, we used several computational tools to classify the missense mutations in the catalytic domain of GAA for their pathogenicity and stability. Eight missense mutations (R437C, G478R, N573H, Y575S, G605D, V642D, L705P, and L712P) were predicted to be pathogenic and destabilizing to the protein structure. These mutations were further subjected to phenotyping analysis using SNPeffect 4.0 to predict the chaperone binding sites and structural stability of the protein. The mutations R437C and G478R were found to compromise the chaperone-binding activity with GAA. Molecular docking analysis revealed that the G478R mutation to be more significant and hinders binding to the DNJ (Miglustat) compared with the R437C. Further molecular dynamic analysis for the two mutations demonstrated that the G478R mutation was acquired higher deviation, fluctuation, and lower compactness with decreased intramolecular hydrogen bonds compared to the mutant R437C. These data are expected to serve as a platform for drug design against Pompe disease and will serve as an ultimate tool for variant classification and interpretations. PMID- 30281820 TI - Opportunities and challenges for intranasal oxytocin treatment studies in nonhuman primates. AB - Nonhuman primates provide a human-relevant experimental model system to explore the mechanisms by which oxytocin (OT) regulates social processing and inform its clinical applications. Here, we highlight contributions of the nonhuman primate model to our understanding of OT treatment and address unique challenges in administering OT to awake behaving primates. Prior preclinical research utilizing macaque monkeys has demonstrated that OT can modulate perception of other individuals and their expressions, attention to others, imitation, vigilance to social threats, and prosocial decisions. We further describe ongoing efforts to develop an OT delivery system for use in experimentally naive juvenile macaque monkeys compatible with naturalistic social behavior outcomes. Finally, we discuss future directions to further develop the rhesus monkey as a preclinical test bed to evaluate the effects of OT exposure and advance efforts to translate basic science OT research into safe and effective OT therapies. PMID- 30281821 TI - Transcranial direct-current stimulation reduces nociceptive behaviour in an orofacial pain model. AB - BACKGROUND: Transcranial direct-current stimulation (tDCS) is a noninvasive method of brain stimulation suggested as a therapeutic tool for pain and is related to the reversal of maladaptive plasticity associated with chronic pain. OBJECTIVES: This study investigated the effect of tDCS, a non-pharmacological therapy, on local mechanical hyperalgesia, and remote thermal hyperalgesia in rats submitted to orofacial inflammatory pain model, by facial von Frey and hot plate tests, respectively. In addition, we evaluated levels of BDNF, NGF, IL-10 and IL-6 in the brainstem and blood serum of these animals at 24 hours and 7 days after the end of tDCS treatment. METHODS: Rats were subjected to temporomandibular joint pain and treated with tDCS. The animals were divided into control, pain and pain + treatment groups. Mechanical and thermal hyperalgesia were evaluated at baseline, 7 days after administration of complete Freund's adjuvant, and immediately, 24 hours, and 7 days after the tDCS treatment. Neuroimmunomodulators levels were determined by ELISA. Statistical analyses were performed by (GEE)/Bonferroni (behavioural tests), three-way ANOVA/SNK (neurochemical tests) and Kruskal-Wallis (histological analysis). RESULTS: Transcranial direct-current stimulation reduced mechanical and thermal hyperalgesia (P < 0.01). We observed interaction between factors (pain and treatment) increasing brainstem BDNF (P < 0.01) and NGF (P < 0.05) levels. Furthermore, we found an increase in IL-6 and IL-10 levels in the brainstem at 24 hours and 7 days after tDCS, respectively. CONCLUSION: We showed that tDCS reduces thermal and mechanical hyperalgesia induced by orofacial pain until 7 days after treatment. These findings demonstrate that tDCS was effective in the control of orofacial inflammatory pain. PMID- 30281823 TI - Combined effect of anti-high-mobility group box-1 monoclonal antibody and peramivir against influenza A virus-induced pneumonia in mice. AB - Human pandemic H1N1 2009 influenza virus causes significant morbidity and mortality with severe acute lung injury due to the excessive inflammatory reaction, even with neuraminidase inhibitor use. The anti-inflammatory effect of anti-high-mobility group box-1 (HMGB1) monoclonal antibody (mAb) against influenza pneumonia has been reported. In this study, we evaluated the combined effect of anti-HMGB1 mAb and peramivir against pneumonia induced by influenza A (H1N1) virus in mice. Nine-week-old male C57BL/6 mice were inoculated with H1N1 and treated with intramuscularly administered peramivir at 2 and 3 days post infection (dpi). The anti-HMGB1 mAb or a control mAb was administered at 2, 3, and 4 dpi. Survival rates were assessed, and lung lavage and pathological analyses were conducted at 5 and 7 dpi. The combination of peramivir with the anti-HMGB1 mAb significantly improved survival rate whereas the anti-HMGB1 mAb alone did not affect virus proliferation in the lungs. This combination therapy also significantly ameliorated histopathological changes, neutrophil infiltration, and macrophage aggregation by inhibiting HMGB1, inflammatory cytokines, and oxidative stress. Fluorescence immunostaining showed that the anti HMGB1 mAb inhibited HMGB1 translocation from type I alveolar epithelial cells. In summary, combining anti-HMGB1 with conventional anti-influenza therapy might be useful against severe influenza virus infection. PMID- 30281822 TI - Dispersal and female philopatry in a long-term, stable, polygynous gibbon population: Evidence from 16 years field observation and genetics. AB - Gibbons are generally reported to live in small socially monogamous family groups in which both sexes disperse when they reach maturity. For the first time, we documented the dispersal pattern in a population of gibbons living in stable polygynous groups (Nomascus concolor) integrating 16 years' field observation and genetic information from fecal DNA. All subadult males except for one dispersed at 9.8 +/- 1.4 years of age (range: 8-12, N = 10). The last male remained in his natal group and obtained the breeding position at age 11 by evicting the original dominant male. Females reached sexual maturity (as evidenced by the change in body color from black to yellow) at 8 years (N = 4). Three of them dispersed and one obtained a position as a breeding female and bred in her natal group. We also observed one female returning to her natal group with her infant after her presumed father was taken over by a neighboring male. We identified only three mtDNA haplotypes from 22 individuals at Dazhaizi. Individuals in one group shared the same haplotype, with only one exception. Genetic results showed that the two breeding females were mother-daughter pairs in all three study groups at the end of this study, implying some degree of female philopatry. We argue that in the case of black crested gibbons, dispersal decisions appear to represent highly opportunistic events in response to reproductive opportunities in their natal and neighboring groups. PMID- 30281824 TI - The efficacy of nasal airway stent (Nastent) on obstructive sleep apnoea and prediction of treatment outcomes. AB - BACKGROUND: Obstructive sleep apnoea (OSA) is characterised by recurrent episodes of partial or complete upper airway collapse during sleep and is highly prevalent in the general population. The nasopharyngeal airway stent (Nastent) is a specifically designed, preformed silicone tube that intends to maintain the upper airway patency during sleep and reduce snoring and sleep apnoea. OBJECTIVE(S): The purpose of this study was to determine the efficacy of Nastent treatment and examine predictors for Nastent treatment outcomes in patients with OSA. METHODS: Consecutive thirty patients were enrolled in this study. Cephalometric radiographs were obtained to analyse the pharyngeal and craniofacial morphology. Before and after Nastent treatment, we evaluated OSA using a portable sleep study. RESULTS: Twenty-nine subjects completed this study. There were significant decreases in the respiratory event index (REI) (22.4 +/- 14.1 to 15.7 +/- 10.4, P < 0.01) and a significant increase in the lowest SpO2 (81.9 +/- 7.5 to 86.6 +/- 4.8, P < 0.01) by Nastent treatment. Subjects were divided into responders and non-responders based on reduction in REI of >50% compared with baseline REI. We evaluated the ratio of inferior airway width and middle airway width (IAW/MAW) on cephalograms as the index of the narrowest airway site. The IAW/MAW was significantly higher in responders than in non-responders (1.4 +/- 0.9 vs 0.9 +/- 0.4, P < 0.01) and predicted treatment responders with high accuracy (sensitivity: 90.9%, specificity: 88.9%, when IAW/MAW was set at 1.10). CONCLUSIONS: The Nastent device improved OSA, and a narrower velopharynx than hypopharynx predicted treatment response with a good sensitivity and specificity. PMID- 30281825 TI - Standard growth and diarrhea-associated growth faltering in captive infant rhesus macaques (Macaca mulatta). AB - Reference growth studies of captive rhesus macaque infants have not accounted for diarrhea and the potential for growth stunting or growth faltering. Healthy infants without diarrhea could be used to build a standard growth chart and a tool used to detect growth faltering associated with diarrhea. We hypothesized infants who develop diarrhea during the first year of life would experience decreased linear weight gain compared to healthy infants, and we used healthy infants to establish standard growth of male and female infants. We hypothesized the lower 3rd percentile of standard growth would be cut-off criteria used in screening for diarrhea-associated growth faltering. Using a retrospective cohort of 6,510 infant weight records in a multiple linear regression, daily weight gain through the first year of life was determined by sex, housing type, and health status. Male standard growth was 4.1 g/day (95%CI: 4.0-4.2 g/day) in corrals and 4.7 g/day (95%CI: 4.5-4.8 g/day) in shelter housing. Female standard growth was 4.0 g/day (95%CI: 3.8-4.2 g/day) in corrals and 4.4 g/day (95%CI: 4.0-4.7 g/day) in shelter housing. Diarrhea was significantly associated with decreased linear weight gain by up to 34% during the first year of life. Odds of growth faltering of infants, defined as those falling below the 3rd percentile of standard growth, were at least 8.9 higher given a history of diarrhea compared to healthy. The growth faltering cut-off criteria had a sensitivity of at least 53% for males and females to screen for diarrhea in infants between 6 and 12 months in shelters housing. Interinstitutional collaborations of infant rhesus macaque weight records would refine the standard growth charts and cut-off criteria, and additional morphometric data would provide a more nuanced picture of growth stunting. PMID- 30281826 TI - Orofacial pain and its potential oral causes in older people with mild cognitive impairment or dementia. AB - BACKGROUND: The number of people with dementia and natural dentition is growing. As dementia progresses, the degree of self-care decreases and the risk of oral health problems and orofacial pain increases. OBJECTIVES: To examine and compare the presence of orofacial pain and its potential causes in older people with Mild Cognitive Impairment (MCI) or dementia. METHODS: In this cross-sectional observational study, the presence of orofacial pain and its potential causes was studied in 348 participants with MCI or dementia with all levels of cognitive impairment in two outpatient memory clinics and ten nursing homes. RESULTS: Orofacial pain was reported by 25.7% of the 179 participants who were considered to present a reliable pain self-report (Mini-Mental State Examination score >=14 points), while it could not be determined in people with more severe cognitive impairment. The oral health examination of the 348 participants indicated that potential painful conditions, such as coronal caries, root caries, tooth root remnants or ulcers were present in 50.3%. There was a significant correlation between the level of cognitive impairment and the number of teeth, r = 0.185, P = 0.003, teeth with coronal caries, r = -0.238, P < 0.001, and the number of tooth root remnants, r = -0.229, P = 0.004, after adjusting for age. CONCLUSIONS: This study indicated that orofacial pain and its potential causes were frequently present in participants with MCI or dementia. Therefore, a regular oral examination by (oral) healthcare providers in people with MCI or dementia remains imperative, even if no pain is reported. PMID- 30281827 TI - Social behavioral correlates of Kaposi sarcoma-associated herpesvirus infection among Han and Uygur populations in Xinjiang, China. AB - BACKGROUND: Kaposi sarcoma-associated herpesvirus (KSHV) is endemic in Xinjiang, China and its prevalence varies considerably across ethnic groups. The current study explored the prevalence and correlates of KSHV infection among Han and Uygur populations in Xinjiang. METHODS: A cross-sectional study, including 282 Han ethnicity and 312 Uygur, was conducted in Xinjiang, China. All participants underwent face to face questionnaire interview. Plasma samples were collected and screened for KSHV infection using immunofluorescence assay. Univariate and multivariate analyses were conducted to examine the correlates of KSHV seropositivity. RESULTS: The KSHV seroprevalence was 41.6% (95% confidence interval [CI], 37.6-45.6) overall and was higher in the Uygur group (59.9%; 95% CI, 54.3-65.4) than the Han group (21.3%; 95% CI, 16.6-26.5). A significant difference in the geometric mean titer (GMT) of the KSHV antibodies was detected between the Uygur and Han groups (158.2; interquartile range [IQR], 80-320 vs 89.1; IQR, 40-160; P < 0.001). After adjusting for potential confounders, Uygur ethnicity (odds ratios [OR], 5.96; 95% CI, 4.05-8.90), age greater than or equal to 50 years (OR, 1.84; 95% CI, 1.24-2.77), and preference for meat diet (OR, 2.15; 95% CI, 1.05-4.46) were significantly associated with increased odds of KSHV seropositivity. CONCLUSION: The study demonstrated high prevalence and correlates of KSHV infection in both Han and Uygur populations in Xinjiang, China. There is an urgent need for programmatic adaptation to address primary prevention interventions of KSHV infection in this endemic region. PMID- 30281828 TI - Editorial: less acid, less cancer?

PMID- 30281832 TI - Short and long-term effectiveness and safety of vedolizumab in inflammatory bowel disease: results from the ENEIDA registry. AB - BACKGROUND: Effectiveness of vedolizumab in real world clinical practice is unknown. AIM: To evaluate the short and long-term effectiveness of vedolizumab in patients with inflammatory bowel disease (IBD). METHODS: Patients who received at least 1 induction dose of vedolizumab were included. Effectiveness was defined based on Harvey-Bradshaw index (HBI) in Crohn's disease (CD) and Partial Mayo Score (PMS) in ulcerative colitis (UC). Short-term response was assessed at week 14. Variables associated with short-term remission were identified by logistic regression analysis. The Kaplan-Meier method was used to evaluate the long-term durability of vedolizumab treatment. Cox model was used to identify factors associated with discontinuation of treatment and loss of response. RESULTS: 521 patients were included (median follow-up 10 months [interquartile range 5-18 months]). At week 14, 46.8% had remission and 15.7% clinical response. CD (vs UC), previous surgery, higher CRP concentration and disease severity at baseline were significantly associated with impaired response. The rate of vedolizumab discontinuation was 37% per patient-year of follow-up (27.6% in UC and 45.3% in CD, P < 0.01). CD (vs UC), anaemia at baseline, steroids during induction and CRP concentration were associated with lower durability of treatment. Seven per cent of patients developed adverse events, infections being the most frequent. CONCLUSIONS: Over 60% of IBD patients respond to vedolizumab. Many patients discontinue treatment over time. CD and disease burden impair both short- and long-term response. Vedolizumab seems to be safe in clinical practice.

AB - BACKGROUND: Upper respiratory tract (URT) endoscopic examination is a routine part of prepurchase examinations. Discrepancies have been documented in the assessment of arytenoid function grades (AFG) between veterinarians. OBJECTIVES: To document intra- and interobserver agreement for a population of multi experience level veterinarians for assessment of AFG of 2-year-old Thoroughbreds. STUDY DESIGN: Observational cohort study. METHODS: One-hundred and fourteen URT videoendoscopic examinations were evaluated by 10 veterinarians. Veterinarians were categorised based on experience, into five groups, each group with two veterinarians. Arytenoid function was graded using the Havemeyer ordinal scale and then reclassified by the authors dichotomously into 'meets conditions of sale' (MCS) or 'does not meet conditions of sale'(DNMCS). Interobserver agreement of arytenoid function was assessed across all 10 veterinarians using Fleiss' kappa and between veterinarians of similar experience levels in the five subgroups using Cohen's unweighted (k) and Cohen's linear weighted kappa (Ck). Intraobserver agreement was similarly calculated for each reviewer using 22 repeated video clips. RESULTS: Overall interobserver agreement using ordinal scales was fair (k = 0.27, 95% CI 0.22-0.31) to moderate (mean weighted Ck = 0.57, 95% CI 0.46-0.69) depending on statistical methodology used. Using the dichotomous classification, interobserver agreement was good (k = 0.7, 95% CI 0.63-0.77). Overall intraobserver agreement using ordinal scales was fair (mean k = 0.26, 95% CI 0.14-0.38) to good (mean Ck = 0.61, 95% CI 0.50-0.71); and for the dichotomous reclassification it was good (k = 0.73, 95% CI 0.59-0.87). Experience level differences were identified. MAIN LIMITATIONS: The low number of veterinarians in each experience subgroup. CONCLUSIONS: Subjectivity exists in arytenoid function grading, despite the existence of a well-defined scale. Agreement variation exists depending on the grading scales and statistical methods used for analysis. Future studies pre- and post veterinarian training are indicated to determine if agreement can be improved. PMID- 30281843 TI - Polycythemia vera and essential thrombocythemia: 2019 update on diagnosis, risk stratification and management. AB - Disease Overview: Polycythemia vera (PV) and essential thrombocythemia (ET) are myeloproliferative neoplasms respectively characterized by erythrocytosis and thrombocytosis; other disease features include leukocytosis, splenomegaly, thrombosis, bleeding, microcirculatory symptoms, pruritus, and risk of leukemic or fibrotic transformation. Diagnosis: Bone marrow morphology remains the cornerstone of diagnosis. In addition, the presence of JAK2 mutation is expected in PV while approximately 90% of patients with ET express mutually exclusive JAK2, CALR, or myeloproliferative leukemia mutations. In ET, it is most important to exclude the possibility of prefibrotic myelofibrosis. Survival: Median survivals are 14 years for PV and 20 years for ET; the corresponding values for younger patients are 24 and 33 years. Certain mutations (mostly spliceosome) and abnormal karyotype might compromise survival in PV and ET. Life-expectancy in ET is inferior to the control population. Driver mutations have not been shown to affect survival in ET. Risk of thrombosis is higher in JAK2-mutated ET. Leukemic transformation rates at 10 years are estimated at <1% for ET and 3% for PV. Thrombosis Risk: In PV, 2 risk categories are considered: high (age > 60 years or thrombosis history present) and low (absence of both risk factors); in ET, 4 risk categories are considered: very low (age <= 60 years, no thrombosis history, JAK2 wild-type), low (same as very low but JAK2 mutation present), intermediate (age > 60 years, no thrombosis history, JAK2 wild-type) and high (thrombosis history present or age > 60 years with JAK2 mutation). Risk-Adapted Therapy: The main goal of therapy in both PV and ET is to prevent thrombohemorrhagic complications. All patients with PV require phlebotomy to keep hematocrit below 45% and once- or twice-daily aspirin (81 mg), in the absence of contraindications. Very low-risk ET might not require therapy while aspirin therapy is advised for low-risk disease. Cytoreductive therapy is recommended for high-risk ET and PV but it is not mandatory for intermediate-risk ET. First-line drug of choice for cytoreductive therapy, in both ET and PV, is hydroxyurea and second-line drugs of choice are interferon-alpha and busulfan. We do not recommend treatment with ruxolutinib in PV, unless in the presence of severe and protracted pruritus or marked splenomegaly that is not responding to the aforementioned drugs. PMID- 30281842 TI - Special considerations for clinical trials in fibrodysplasia ossificans progressiva (FOP). AB - Clinical trials for orphan diseases are critical for developing effective therapies. One such condition, fibrodysplasia ossificans progressiva (FOP; MIM#135100), is characterized by progressive heterotopic ossification (HO) that leads to severe disability. Individuals with FOP are extremely sensitive to even minor traumatic events. There has been substantial recent interest in clinical trials for novel and urgently-needed treatments for FOP. The International Clinical Council on FOP (ICC) was established in 2016 to provide consolidated and coordinated advice on the best practices for clinical care and clinical research for individuals who suffer from FOP. The Clinical Trials Committee of the ICC developed a focused list of key considerations that encompass the specific and unique needs of the FOP community - considerations that are endorsed by the entire ICC. These considerations complement established protocols for developing and executing robust clinical trials by providing a foundation for helping to ensure the safety of subjects with FOP in clinical research trials.

Growth differentiation factor 8 (Myostatin, GDF8) and its homologue growth differentiation factor 11 (GDF11), members of the TGF-beta super-family, play an important role in muscle regeneration and bone metabolism in healthy individuals. However, their association with BMD in AN is unknown. The present study was undertaken to investigate the relationship between GDF8, GDF11 and BMD in adolescent girls with AN. METHODS: Serum GDF8, GDF11 and BMD were determined in 25 girls (12-16 years old) with AN and 31 healthy girls (12-16 years old). RESULTS: Growth differentiation factor 8 levels were lower in AN subjects. On the contrary, GDF11 levels were higher in AN subjects than controls. There was no relationship between GDF8 and BMD. A significant negative correlation between GDF11 and BMD was found. In multiple linear stepwise regression analysis, BMI, 25-hydroxyvitamin D, GDF11, or lean mass, but not fat mass and GDF8, were independent predictors of BMD in the AN and control groups separately. CONCLUSIONS: Growth differentiation factor 11 was independent predictor of BMD in girls with AN. It suggested that GDF11 exerts a negative effect on bone mass.

AB - Methanotrophs are remarkable bacteria that utilise large quantities of copper (Cu) to oxidize the potent greenhouse gas methane. To help provide the Cu they require for this process some methanotrophs can secrete the Cu-sequestering modified peptide methanobactin. These small molecules bind Cu(I) with very high affinity and crystal structures have provided insight into why this is the case, and also how the metal ion may be released within the cell. A much greater proportion of methanotrophs possess a member of a newly discovered bacterial family of copper storage proteins (the Csps). These are tetramers of four-helix bundles whose cores are lined with Cys residues enabling the binding of large numbers of Cu(I) ions. In methanotrophs, a Csp exported from the cytosol stores Cu(I) for the active site of the ubiquitous enzyme that catalyses the oxidation of methane. The presence of cytosolic Csps, not only in methanotrophs but in a wide range of bacteria, challenges the dogma that these organisms have no requirement for Cu in this location. The properties of the Csps, with an emphasis on Cu(I) binding and the structures of the sites formed, are the main focus of this review.

AB - OBJECTIVE: B lymphocyte activating factor (BAFF), a member of the tumour necrosis factor superfamily, is essential for B cell activation, differentiation and survival. Elevated circulating BAFF levels have been found in patients with several autoimmune conditions, including Graves' disease. In addition, BAFF gene variants have been associated with Graves' disease in a Taiwanese cohort, and with several other autoimmune conditions in non-Taiwanese populations. DESIGN AND METHODS: We performed a case-control association study to investigate two BAFF polymorphisms (rs9514828 and rs4000607) in a UK cohort of 444 patients with Graves' disease. Genotype frequencies were compared to those from 447 local controls and more than 5000 healthy controls from the Wellcome Trust case-control consortium (WTCCC2). RESULTS: There was a significant difference in the frequency of the AA genotype at rs4000607 between the Graves' disease cohort and both the local controls (P = 0.045) and the WTCCC2 controls (P = 4.56 * 10-6 ). Furthermore, the frequency of the A allele was found to be increased in the Graves' disease group compared to WTCCC2 controls (P = 0.02, OR 1.20 (95% CI 1.03 1.41). No association was observed at the rs9514828 locus. CONCLUSION: Dysfunction of the humoral immune system is an obligatory pathophysiological component of Graves' disease, hence BAFF is an excellent functional candidate gene. We have demonstrated, for the first time, a significant association of the BAFF polymorphism rs4000607 with Graves' disease in a UK cohort. Further work to elucidate the role of BAFF in the pathogenesis of Graves' disease is now warranted.

AB - Engineering the properties of conjugated materials in the solid state is an unsolved, ongoing challenge important to fundamental understanding of how non covalent interactions dictate packing and key properties, as well as the development of technologies based in organic optoelectronics. The most common design paradigm of such materials divide them into a "main chain" with extended conjugation, the chemical structure of which determines optoelectronic properties, and "side chains" not conjugated to the backbone, which provide solubility when they are long alkyl chains. This paper describes comparisons between phenylene-ethynylene molecules in which slight changes to the structure of "side chains"-swapping hydrogen and fluorine atomic position on an aromatic ring-results in unexpectedly large changes in the solid-state optical properties. In a pair of anisyl-terminated three-ring phenylene-ethynylenes, switching the side chain arenes of benzyl esters from 2,4,6-trifluoro to 2,3,6-trifluoro results in a shift in fluorescence emission spectra of over 100 nm, as well as the opposite direction of force-induced shifting of emission. Through a combination X-ray crystal structures, electronic structure calculations, and comparisons with other derivatives, we describe how the 2,4,6-trifluorinated side chains yield cofacial fluoroarene-arene stacking interactions that twist the PE backbone out of conjugation, while the 2,3,6-trifluoro side chains do not stack, instead yielding more coplanar PE backbones that form intermolecular aggregates. Overall, this work demonstrates how slight modifications to parts of conjugated materials normally considered ancillary to optoelectronic properties can determine their solid-state properties, epitomizing the challenge of rational design but at the same time offering opportunities for materials discovery and improved understanding of non-covalent interactions. PMID- 30281849 TI - Immediate and early implant placement in single-tooth gaps in the anterior maxilla: A prospective study on ridge dimensional, clinical, and aesthetic changes. AB - OBJECTIVES: This prospective study evaluated the impact of timing of placement (immediate and early) on the horizontal ridge dimensional changes, clinical, and aesthetic outcomes of implants placed in single-tooth gaps in the anterior maxilla. MATERIALS AND METHODS: Implants were placed in single-tooth gaps in the anterior maxilla of 30 patients, either immediately after extraction (Group A, n = 15) or after a healing period of 4-8 weeks (Group B, n = 15). In both groups, implant placement was followed by a 3- to 4-month period of non-submerged healing, after which definitive crowns were placed. Study models were obtained before extraction (T0), at implant placement (T1), at the insertion of a definitive crown (T2), and 1-year thereafter (T3). Horizontal ridge dimensional changes were measured by superimposing the optical scans of the study models from different time-points. Radiographs and photographs were used to evaluate changes in marginal bone levels and soft tissue recession. Aesthetic evaluation was carried out using the Pink and White Esthetic Score (PES and WES) indices. Patient-reported outcomes were measured using a subjective questionnaire. RESULTS: A 100% implant survival rate was observed in both groups after a 1-year follow-up. Analysis showed a labial horizontal tissue dimensional change of 0.61 mm and 0.72 mm from T0 to T3 in Groups A and B, respectively. Acceptable PES values were observed in both groups (Group A: 9.40; Group B: 9.27) after the 1 year follow-up period. No incidence of advanced mucosal recession was observed between definitive crown insertion and 1-year follow-up in both groups. No significant changes were observed for all other measured variables at different time-points. CONCLUSIONS: Immediate and early placed implants in single-tooth gaps in the anterior maxilla showed similar ridge dimensional changes as well as acceptable clinical, aesthetic, and patient-centred outcomes in the short-term (1 year follow-up).

AB - The sacrospinous (SS) and sacrotuberous (ST) ligaments form a complex at the posterior pelvis, with an assumed role as functional stabilizers. Experimental and clinical research has yielded controversial results regarding their function, both proving and disproving their role as pelvic stabilizers. These findings have implications for strategies for treating pelvic injury and pain syndromes. The aim of the present simulation study was to assess the influence of altered ligament function on pelvis motion. A finite elements computer model was used. The two-leg stance was simulated, with the load of body weight applied via the fifth lumbar vertebra and both femora, allowing for nutation of the sacroiliac joint. The in-silico kinematics were validated with in-vitro experiments using the same scenario of load application following SS and ST transection in six human cadavers. Modeling of partial or complete ligament failure caused significant increases in pelvis motion. This effect was most pronounced if the SS and ST were affected with 164% and 182%, followed by the sacroiliac and iliolumbar ligaments with 123% and 147%, and the pubic ligaments with 113% and 119%, for partial and complete disruption, respectively. Simultaneous ligament transection multiplied the effects on pelvis motion by up to 490%. Unilateral ligament injury altered the motion at the pelvis contralaterally. The experiments presented here provide strong evidence for the stabilizing role of the SS and ST. A fortiori, the instability resulting from partial or complete SS and ST injury merits consideration in treatment strategies involving these ligaments as important stabilizers. Clin. Anat., 2018.

AB - Because of a general lack of knowledge regarding the precise anatomy of the seminal vesicle system, efforts to use transurethral seminal vesiculoscopy (TSV) are currently constrained. We investigated 26 normal adult male specimens. Contrast medium was injected into the seminal vesicle system in 18 specimens and the openings of the ejaculatory ducts were examined with an operating microscope. India ink was injected into the urethra in four specimens to investigate the function of the ejaculatory duct valve. Another four specimens were examined histologically to identify the anatomical relationships of the seminal vesicle system. We found that the openings of the ejaculatory ducts were covered by the ejaculatory duct valve, which could be classified into two types and acted as a one-way valve. The apex of the seminal colliculus together with the right and left openings of the ejaculatory ducts formed a shape resembling an isosceles triangle. This could be used to locate the openings of the ejaculatory ducts during TSV. The ejaculatory ducts can be classified into two types according to their course. During surgery, efforts must be made to protect the ejaculatory duct valve. During inspection or surgery, the second segment and the angles of the ejaculatory ducts, particularly in Type Ib and Type II cases, require particular attention. Clin. Anat., 2018.

AB - The adverse effects formaldehyde fixation has on tissues both gross anatomically and histologically are well documented. Consequently, researchers are seeking alternative embalming techniques that better preserve in vivo characteristics of tissues. Phenol-based embalming is one method that has shown promise in its ability to adequately preserve the in vivo qualities of tissues through preliminary explorations at the gross anatomical level. The literature on phenol based embalming is currently scarce, especially with regard to its effects on tissues at the microscopic level. For the current study we aimed to document the histologic effects of a formaldehyde-free phenol-based embalming solution on neural tissue, with the hope of providing novel insight into the effects of soft embalming on tissues at the microscopic level. Cerebral and cerebellar tissue obtained from porcine brains was fixed in phenol- and formaldehyde-based fixatives; the latter served as a control. Fixed samples were processed for histological analysis. The phenol-based embalming solution provided excellent preservation of the cerebral and cerebellar tissue morphology. Of note was the decrease in separation artifact seen in both tissue types relative to the control tissue, as well as anomalous circular artifacts in the white matter. The results of this study indicate that the phenol-based embalming solution preserves neural tissue at the histological level, perhaps superiorly in many aspects when compared to the formaldehyde-fixed samples. Further investigations of both gross anatomy and histology are recommended on the basis of these promising new findings to determine its potential utilities within research and education. Clin.

PMID- 30281855 TI - Polyamine-independent growth and biofilm formation, and functional spermidine/spermine N-acetyltransferases in Staphylococcus aureus and Enterococcus faecalis. AB - Polyamines such as spermidine and spermine are primordial polycations that are ubiquitously present in the three domains of life. We have found that Gram positive bacteria Staphylococcus aureus and Enterococcus faecalis have lost either all or most polyamine biosynthetic genes, respectively, and are devoid of any polyamine when grown in polyamine-free media. In contrast to bacteria such as Pseudomonas aeruginosa, Campylobacter jejuni and Agrobacterium tumefaciens, which absolutely require polyamines for growth, S. aureus and E. faecalis grow normally over multiple subcultures in the absence of polyamines. Furthermore, S. aureus and E. faecalis form biofilms normally without polyamines, and exogenous polyamines do not stimulate growth or biofilm formation. High levels of external polyamines, including norspermidine, eventually inhibit biofilm formation through inhibition of planktonic growth. We show that spermidine/spermine N acetyltransferase (SSAT) homologues encoded by S. aureus USA300 and E. faecalis acetylate spermidine, spermine and norspermidine, that spermine is the more preferred substrate, and that E. faecalis SSAT is almost as efficient as human SSAT with spermine as substrate. The polyamine auxotrophy, polyamine-independent growth and biofilm formation, and presence of functional polyamine N acetyltransferases in S. aureus and E. faecalis represent a new paradigm for bacterial polyamine biology. PMID- 30281856 TI - The microbiome of the "sterile" pustules in palmoplantar pustulosis. AB - The skin microbiome influences skin pathophysiology. Palmoplantar pustulosis (PPP) is a chronic skin disease characterized by infectious-like pustules on the palms and soles. These pustules are thought to be sterile because bacterial cultures obtained from the pustules are negative. However, culture methods are limited in their ability to identify all bacteria on the skin. We hypothesized that the "sterile" pustules of PPP do not lack bacteria, but rather contain a microbiome. To test this hypothesis, we identified bacteria in "sterile" pustules using non-culture methods. We conducted Sanger and 16S rRNA sequencing using primers specific to the V1-V2 region in PPP-pustulovesicles (PVs) (n = 43) and pompholyx vesicle fluids (n = 15). Sanger sequencing identified some Staphylococcus, Propionibacterium, Streptococcus and Pyrinomonas species in PPP PVs but failed to identify any bacteria in most of the pompholyx vesicles. 16S rRNA sequencing of PPP-PVs indicated the presence of a microbiome that included various phyla, including Firmicutes, Proteobacteria, Actinobacteria and Bacteroidetes. At the genus level, smokers had higher levels of Staphylococcus in PPP-PVs compared with non-smokers. These results indicate that a microbiome exists in "sterile" pustules of PPP and that PPP smokers had higher levels of Staphylococcus in pustules. It is therefore necessary to reconsider the pathogenesis of PPP from the perspective of the microbiome. PMID- 30281857 TI - Comparison of autogenous and allograft bone rings in surgically created vertical bone defects around implants in a sheep model. AB - OBJECTIVES: The aim of this study was to compare autogenous and allograft bone rings in surgically created vertical bone defects. MATERIAL AND METHODS: Four male, 1-year-old sheep were used in this study. In each sheep, eight vertical bone defects 7 mm in diameter were created using trephine drill in the iliac wing. Autogenous and allograft bone rings 5 mm in height and 7 mm in diameter were used for vertical augmentation around implants. The study consisted of four groups according to the bone ring type and amount of vertical augmentation, autogenous 2 mm, allograft 2 mm, autogenous 4 mm, and allograft 4 mm. Two of the animals were sacrificed after 4 months, and the remaining two animals were sacrificed after 8 months. Undecalcified sections were prepared from harvested samples. Histological assessment and histomorphometric analysis were performed. RESULTS: Autogenous 2 mm group showed higher values than allograft 2 mm group, and autogenous 4 mm group showed higher values than allograft 4 mm group in terms of bone area and bone-to-implant contact (BIC) after 4 months. However, allograft 2 mm group showed higher bone area and BIC values than autogenous 2 mm group after 8 months. Also, autogenous 4 mm and allograft 4 mm groups showed comparable results after 8 months. Allograft 2 mm and allograft 4 mm groups showed higher bone area and BIC values at 8 months compared with 4 months. CONCLUSIONS: Allograft bone ring looks promising in augmentation of surgically created vertical bone defects around implants after 8 months of healing. PMID- 30281858 TI - The frequency architecture of brain and brain body oscillations: an analysis. AB - Research on brain oscillations has brought up a picture of coupled oscillators. Some of the most important questions that will be analyzed are, how many frequencies are there, what are the coupling principles, what their functional meaning is, and whether body oscillations follow similar coupling principles. It is argued that physiologically, two basic coupling principles govern brain as well as body oscillations: (i) amplitude (envelope) modulation between any frequencies m and n, where the phase of the slower frequency m modulates the envelope of the faster frequency n, and (ii) phase coupling between m and n, where the frequency of n is a harmonic multiple of m. An analysis of the center frequency of traditional frequency bands and their coupling principles suggest a binary hierarchy of frequencies. This principle leads to the foundation of the binary hierarchy brain body oscillation theory. Its central hypotheses are that the frequencies of body oscillations can be predicted from brain oscillations and that brain and body oscillations are aligned to each other. The empirical evaluation of the predicted frequencies for body oscillations is discussed on the basis of findings for heart rate, heart rate variability, breathing frequencies, fluctuations in the BOLD signal, and other body oscillations. The conclusion is that brain and many body oscillations can be described by a single system, where the cross talk - reflecting communication - within and between brain and body oscillations is governed by m : n phase to envelope and phase to phase coupling.

PMID- 30281860 TI - Solution-Processable Two-Dimensional In2 Se3 Nanosheets as Efficient Photothermal Agents for Elimination of Bacteria. AB - Two-dimensional (2D) nanoflakes represent an appealing class of materials for optoelectronics applications due to their unique layered structures and excellent electronic properties. However, the lack of easy-to-manipulate and effective methods for large-scale production of these 2D materials limits their potential for applications. Also, few efforts have been made to explore their applications in biological fields. This work reports the preparation of large quantities of 2D In2 Se3 nanosheets through a solvent exfoliation technique. Transmission electron microscopy and atomic force microscopy results show that the In2 Se3 nanosheets are obtained with lateral sizes of tens of nanometers to hundreds of nanometers and thickness of 2-17 layers. Raman features coupled with the X-ray diffractometry results unequivocally confirm the as-prepared In2 Se3 nanosheets to be alpha phase. Moreover, these alpha-In2 Se3 nanosheets exhibit an excellent near-infrared (NIR) photothermal performance under an 808 nm laser irradiation. NIR photo-excitation of the alpha-In2 Se3 nanosheets in the presence of bacteria leads to a significant antibacterial effect, suggesting that these nanosheets have great potential to be photothermal antibacterial agents. Our work on alpha In2 Se3 nanosheets presents an available method for exfoliating 2D layered materials, and highlights the potential application in chemical and biological fields of alpha-In2 Se3 nanosheets. PMID- 30281861 TI - Fundus image classification methods for the detection of glaucoma: A review. AB - Glaucoma is a neurodegenerative illness and is considered as a standout amongst the most widely recognized reasons for visual impairment. Nerve's degeneration is an irretrievable procedure, so the diagnosis of the illness at an early stage is an absolute requirement to stay away from lasting loss of vision. Glaucoma effected mainly because of increased intraocular pressure, if it is not distinguished and looked early, it can result in visual impairment. There are not generally evident side effects of glaucoma; thus, patients attempt to get treatment just when the seriousness of malady is advanced altogether. Determination of glaucoma often comprises of review of the basic crumbling of the nerve in conjunction with the examination of visual function capacity. This article shows the persistent illustration of glaucoma, its side effects, and the potential people inclined to this malady. The essence of this article is on different classification methods being utilized and proposed by various scientists for the identification of glaucoma. This article audits a few division and segmentation methodologies that are exceptionally useful for recognizable proof, identification, and diagnosis of glaucoma. The research related to the findings and the treatment is likewise evaluated in this article. PMID- 30281862 TI - Independent homoploid hybrid speciation events in the Macaronesian endemic genus Argyranthemum. AB - Well-characterized examples of homoploid hybrid speciation (HHS) are rare in nature, yet they offer the potential to study a number of evolutionary processes. In this study, we investigate putative homoploid hybrid species in the genus Argyranthemum (Asteraceae), a group of plants endemic to the Macaronesian archipelagos of the North Atlantic Ocean. We specifically address a number of knowledge gaps surrounding the origin(s) of A. sundingii and A. lemsii, which are thought to be derived from the same parental cross. Comparisons of leaf morphology suggest that A. sundingii and A. lemsii are distinct from their parental progenitors and distinguishable from each other based on leaf area. Ecological niche modelling (ENM) demonstrated that the homoploid hybrid species occupy novel habitats that are intermediate relative to the parental species. Nuclear simple sequence repeat markers (SSRs) and single nucleotide polymorphism (SNP) data indicate that the homoploid hybrid species are distinct from the parental taxa, while population-level sampling of chloroplast SSRs and approximate Bayesian computation show that A. sundingii and A. lemsii are independently derived from the same parental cross. As such, Argyranthemum represents an example of independent homoploid hybrid speciation events with evidence of divergence in leaf morphology and adaptation to novel intermediate habitats. On oceanic islands, which are often typified by steep ecological gradients and inhabited by recently derived species with weak reproductive barriers, multiple HHS events from the same parental cross are not only possible but also likely to have played a more important role in oceanic island radiations than we currently think. PMID- 30281864 TI - Digital enhancement of dental enamel microstructure images from intact teeth. AB - Dental enamel is formed by rod-like structures, the enamel prisms. Groups of prisms are packed together in successive horizontal layers of alternating directions, known as Hunter-Schreger bands (HSBs). HSBs are the major microstructural characteristic of mammalian enamel. The pattern of HSBs can vary among mammalian species and this variability may provide relevant information regarding the species life history and taxon identification. In human HSBs can be used as a biometric-based parameter for personal identification in automated systems. The analysis of HSBs has been hampered by technical difficulties. The low contrast between light and dark bands and variations in light intensity may hinder the observation of HSBs in digital images. This article describes a simple and efficient computational procedure that greatly enhances the contrast and minimizes the differences in the intensity of illumination in HSBs images. Its use can significantly increase the quality and the number of HSBs that can be recorded in intact teeth. PMID- 30281863 TI - Cortical bone material strength index and bone microarchitecture in postmenopausal women with atypical femoral fractures. AB - Atypical femoral fractures are rare fractures that occur in the subtrochanteric or diaphyseal region of the femur with minimal or no trauma. Though the association of atypical femoral fractures (AFFs) and bisphosphonate (BP) use is a growing concern in the management of osteoporosis, currently there is little knowledge about which patients may be at risk for an atypical femoral fracture. Given that these fractures initiate in the femoral cortex, we aimed to determine whether cortical bone tissue properties (bone material strength index; BMSi), as measured by in vivo impact microindentation, are altered in atypical fracture patients. We also aimed to identify factors associated with the BMSi measurements. We enrolled postmenopausal women with recent AFFs (n = 15) or hip fractures (Hip Fxs; n = 20), long-term (>5 years) BP users (n = 30), and treatment naive controls (n = 88). We measured total hip and femoral neck BMD by DXA, cortical bone microstructure at the distal tibia by HR-pQCT, and BMSi at the midtibia by impact microindentation. BMSi values were similar in all groups, with no effects of long-term BP use or lower values in patients with AFFs or Hip Fxs, even after multivariable adjustment. BMSi measurements were independent of age, femoral BMD, duration of BP treatment, vitamin D level, and cortical bone microstructure, including cortical porosity and cortical tissue mineral density. In conclusion, impact microindentation values are not negatively affected by long term BP use and do not appear to discriminate individuals who suffer AFFs. Thus, our results do not support clinical use of impact microindentation to identify those at risk for AFFs. This remains to be verified in larger studies.

The role of ACTN3 p.Arg577Ter (R577X) genotype in athletic performance, ageing, and disease. AB - A common null polymorphism in the ACTN3 gene (rs1815739:C>T) results in replacement of an arginine (R) with a premature stop codon (X) at amino acid 577 in the fast muscle protein alpha-actinin-3. The ACTN3 p.Arg577Ter allele (aka p.R577* or R577X) has undergone positive selection, with an increase in the X allele frequency as modern humans migrated out of Africa into the colder, less species-rich Eurasian climates suggesting that the absence of alpha-actinin-3 may be beneficial in these conditions. Approximately 1.5 billion people worldwide are completely deficient in alpha-actinin-3. While the absence of alpha-actinin-3 influences skeletal muscle function and metabolism this does not result in overt muscle disease. alpha-Actinin-3 deficiency (ACTN3 XX genotype) is constantly underrepresented in sprint/power performance athletes. However, recent findings from our group and others suggest that the ACTN3 R577X genotype plays a role beyond athletic performance with effects observed in ageing, bone health, and inherited muscle disorders such as McArdle disease and Duchenne muscle dystrophy. In this review, we provide an update on the current knowledge regarding the influence of ACTN3 R577X on skeletal muscle function and its potential biological and clinical implications. We also outline future research directions to explore the role of alpha-actinin-3 in healthy and diseased populations. PMID- 30281866 TI - Efficacy of house dust mite sublingual tablet in the treatment of allergic rhinoconjunctivitis: A randomized trial in a pediatric population. AB - BACKGROUND: The efficacy and safety of 300 index of reactivity (IR) tablets of house dust mite (HDM) allergen extracts in Japanese pediatric (5-16 years old) patients with allergic rhinitis (AR) were assessed in a double-blind, randomized, placebo-controlled study (JAPIC CTI-152981). METHODS: Patients were randomized 1:1 to HDM sublingual tablets or placebo once daily for 52 weeks. The primary end point was average adjusted symptom score (AASS; average of daily Rhinitis Total Symptom Scores, comprising sneezing, rhinorrhea, nasal congestion, and nasal pruritus, adjusted for rescue medication use), analyzed during Weeks 48-52 (mixed effects model for repeated measures). RESULTS: Of 438 patients randomized, 403 (92%; 193 active, 210 placebo) completed the study. AASS (least-squares [LS] mean [SE]) during Weeks 48-52 was significantly (P = 0.0005) lower in the active group compared with placebo (6.32 [0.20] vs 7.27 [0.19]; relative LS mean difference, 13%). Immunological responses (IgE and IgG4 antibodies specific to antigens of two HDM species) were significantly greater in the active group compared with placebo (P < 0.0001). Almost all patients experienced mild or moderate adverse events (AEs). The most common treatment-related AEs were oral pruritus, mouth edema, throat irritation, and ear pruritus. One patient experienced serious pseudocroup (subglottic laryngitis) that recovered. There were no deaths or anaphylaxis requiring the use of injectable adrenaline. CONCLUSIONS: The HDM tablet significantly improved symptoms of HDM-induced perennial AR and was associated with a significant immunological response. The safety profile in pediatric patients was consistent with that in adults, with no new safety concerns. PMID- 30281867 TI - New Species of Closely Related Endosymbiotic Dinoflagellates in the Greater Caribbean have Niches Corresponding to Host Coral Phylogeny. AB - Symbiotic dinoflagellates in the genus Breviolum (formerly Symbiodinium Clade B) dominate coral communities in shallow waters across the Greater Caribbean. While some formally described species exist, mounting genetic, and ecological evidence indicate that numerous more comprise this genus, many of which are closely related. To test this, colonies of common reef-building corals were sampled across a large geographical range. Phylogenetic and population genetic markers then used to examine evolutionary divergence and delineate boundaries of genetic recombination. Three new candidate species were distinguished by fixed differences in nucleotide sequences from nuclear and chloroplast DNA. Population connectivity was evident within each lineage over thousands of kilometers, however, substantial genetic structure persisted between lineages co-occurring within sampling locations, signifying reproductive isolation. While geographically widespread with overlapping distributions, each species is ecologically distinct, exhibiting specific mutualisms with phylogenetically distinct coral hosts. Moreover, significant differences in mean cell sizes provide some morphological evidence substantiating formal species distinctions. In providing evidence that satisfies the biological, phylogenetic, ecological, and morphological species concepts, we classify and formally name Breviolum faviinorum n. sp., primarily associated with Caribbean corals belonging to the Caribbean subfamily Faviinae; B. meandrinium n. sp., associated with corals belonging to the family Meandrinidae; and B. dendrogyrum n. sp., a symbiont harbored exclusively by the threatened coral Dendrogyra cylindrus. These findings support the primary importance of niche diversification (i.e. host habitat) in the speciation of symbiotic dinoflagellates.

AB - OBJECTIVE: To compare the levels of pain, grip strength, balance and gait in older adults with and without post-Chikungunya chronic arthralgia (PCCA). METHODS: Sixty-two older adults, 30 with and 32 without PCCA participated in the study. Pain level was assessed using a Visual Analogue Scale (VAS). Gait during a 10-m walk was assessed using inertial sensors. Semi-static balance was assessed during an eyes-closed bipedal balance test on a force platform, and grip strength was assessed using a hand dynamometer. RESULTS: Participants with PCCA presented severe levels of pain (VAS > 7.5), poorer balance, lower grip strength, walked slower, with lower cadence and stride length and higher stride time and stride length variability than participants without PCCA (P < 0.001 for all variables). CONCLUSIONS: Older adults with PCCA had high levels of pain, impaired balance and gait and lower grip strength compared to older adults without PCCA.

AB - The PUF RNA-binding protein Puf5 is involved in regulation of the cell wall integrity (CWI) pathway in yeast. Puf5 negatively regulates expression of LRG1 mRNA, encoding for a GTPase-activating protein for Rho1 small GTPase. Here, we further analyzed the effect of Puf5 on LRG1 expression, together with Ccr4 and Pop2 deadenylases, Dhh1 decapping activator, and other PUF proteins. We found that the growth defect of puf5? mutant was enhanced by ccr4? mutation, which was partially suppressed by LRG1 deletion. Consistently, Lrg1 protein level was much more up-regulated in ccr4Delta puf5Delta double mutant than in each single mutant. Interestingly, LRG1 poly(A) tail length was longer in ccr4? mutant but not in puf5? mutant. Thus, Puf5 regulates LRG1 expression independently from Ccr4, although Puf5 recruits the Ccr4-Not deadenylase complex for mRNA destabilization. Unexpectedly, puf6Delta mutation suppressed the growth defect caused by ccr4Delta puf5? mutation. Loss of Rpl43a and Rpl43b ribosomal proteins, the previously identified Puf6 interactors, also suppressed the growth defect of ccr4Delta puf5Delta mutant. Our results suggest that Puf5 functions in the CWI pathway by regulating LRG1 expression in a deadenylase-independent manner, and that Puf6 is involved in the Ccr4- and Puf5-mediated regulation of cell growth through association with Rpl43. PMID- 30281870 TI - A Subset of Paracrine Factors as Efficient Biomarkers for Predicting Vascular Regenerative Efficacy of Mesenchymal Stromal/Stem Cells. AB - Mesenchymal stromal/stem cells (MSCs) have been developed as a promising source for cell-based therapies of ischemic disease. However, there are some hurdles in their clinical application such as poor cell engraftment and inconsistent stem cell potency. In this study, we sought to find biomarkers for predicting potency of MSCs for proangiogenic therapy to improve their beneficial effects. Large variations were observed in proangiogenic factor secretion profiles of conditioned media derived from nine different donor-derived Wharton's jelly (WJ) derived MSCs and 8 factors among 55 angiogenesis-related factors were secreted at considerable levels. Two distinct WJ-MSCs that had the lowest or the highest secretion of these eight factors showed corresponding proangiogenic activities in in vitro angiogenesis assays. When four additional different donor-derived WJ MSCs were further examined, proangiogenic activities in migration and tube formation of endothelial cells and in in vivo Matrigel plug assay were highly consistent with secretion levels of four major factors (angiogenin, interleukin 8, monocyte chemoattractant protein-1, and vascular endothelial growth factor). Such correlation was also observed in vascular regenerative effect in a mouse hind limb ischemia model. Blocking of these four factors by neutralizing antibodies or knockdown of them by siRNA treatment resulted in significant inhibition of proangiogenic activities of not only WJ-MSCs, but also bone marrow derived MSCs. These results suggest that these four factors may represent efficient biomarkers for predicting vascular regenerative efficacy of MSCs. Stem Cells 2018.

PMID- 30281871 TI - Langerhans cell histiocytosis in adults: Advances in pathophysiology and treatment. AB - Langerhans cell histiocytosis (LCH) is a rare systemic disorder characterized by the accumulation of CD1a+/Langerin+ LCH cells and wide-ranging organ involvement. Langerhans cell histiocytosis was formerly referred to as histiocytosis X, until it was renamed in 1987. Langerhans cell histiocytosis beta was named for its morphological similarity to skin Langerhans cells. Studies have shown that LCH cells originate from myeloid dendritic cells rather than skin Langerhans cells. There has been significant debate regarding whether LCH should be defined as an immune disorder or a neoplasm. A breakthrough in understanding the pathogenesis of LCH occurred in 2010 when a gain-of-function mutation in BRAF (V600E) was identified in more than half of LCH patient samples. Studies have since reported that 100% of LCH cases show ERK phosphorylation, indicating that LCH is likely to be a clonally expanding myeloid neoplasm. Langerhans cell histiocytosis is now defined as an inflammatory myeloid neoplasm in the revised 2016 Histiocyte Society classification. Randomized trials and novel approaches have led to improved outcomes for pediatric patients, but no well-defined treatments for adult patients have been developed to date. Although LCH is not fatal in all cases, delayed diagnosis or treatment can result in serious impairment of organ function and decreased quality of life. This study summarizes recent advances in the pathophysiology and treatment of adult LCH, to raise awareness of this "orphan disease". PMID- 30281872 TI - Functional intronic variant of SLC5A10 affects DRG2 expression and survival outcomes of early-stage non-small-cell lung cancer. AB - RegulomeDB is a new tool that can predict the regulatory function of genetic variants. We applied RegulomeDB in selecting putative functional variants and evaluated the relationship between these variants and survival outcomes of surgically resected non-small-cell lung cancer. Among the 244 variants studied, 14 were associated with overall survival (P < 0.05) in the discovery cohort and one variant (rs2257609 C>T) was replicated in the validation cohort. In the combined analysis, rs2257609 C>T was significantly associated with worse overall and disease-free survival under a dominant model (P = 2 * 10-5 and P = 0.001, respectively). rs2257609 is located in the SLC5A10 intron, but RegulomeDB predicted that this variant affected DRG2, not SLC5A10 expression. The expression level of SLC5A10 was not different with the rs2257609 genotype. However, DRG2 expression was different according to the rs2257609 genotype (Ptrend = 0.03) and was significantly higher in tumor than in non-malignant lung tissues (P = 1 * 10-5 ). Luciferase assay also showed higher promoter activity of DRG2 in samples with the rs2257609 T allele (P < 0.0001). rs2257609 C>T affected DRG2 expression and, thus, influenced the prognosis of early-stage non-small-cell lung cancer. This study was approved by the Institutional Review Broad of Kyungpook National University of Hospital (Approval No. KNUMC 2014-04-210-003). PMID- 30281876 TI - Time trends in use of the CHADS2 and CHA2 DS2 VASc scores, and the geographical and specialty uptake of these scores from a popular online clinical decision tool and medical reference. AB - BACKGROUND: The impact of the utilisation of such e-health approaches, including mHealth (use of mobile phones and other wireless technology in the delivery of medical care) assessments of health parameters, or the use of decision aids and online risk calculators over time have not been previously described. The objective of this analysis is to assess the time trends in use of the CHADS2 and CHA2 DS2 VASc scores in e-health, and the geographical and specialty uptake of these scores, using data gleaned from a popular online clinical decision tool and medical reference, MDCalc. We hypothesised that the change in use of the scores would reflect the changes in guidelines and trends in clinical practice. RESULTS: The CHA2 DS2 VASc score was the 20th most popular calculator in 2012, rising to the second most popular calculator in 2018; the CHADS2 score showed the converse, dropping from no. 3 to no. 22. Use of the CHA2 DS2 VASc scores particularly increased in the United States, Canada and Australia over time while the United Kingdom experienced a greater traffic share in 2015. The majority users of the CHADS2 and CHA2 DS2 VASc scores were primary care physicians, with cardiologists being in the minority; the proportion of cardiologists was greater outside USA, compared to within USA. CONCLUSION: Over time, use of the CHA2 DS2 VASc score increased, while use of the CHADS2 score decreased. The change in uptake could partly be related to introduction of guidelines recommending the use of the CHA2 DS2 VASc score for stroke risk stratification.

PMID- 30281874 TI - Genome-wide association study identifies gastric cancer susceptibility loci at 12q24.11-12 and 20q11.21. AB - Gastric cancer is the third leading cause of cancer mortality in Japan and worldwide. Although previous studies identify various genetic variations associated with gastric cancer, host genetic factors are largely unidentified. To identify novel gastric cancer loci in the Japanese population, herein, we carried out a large-scale genome-wide association study using 6171 cases and 27 178 controls followed by three replication analyses. Analysis using a total of 11 507 cases and 38 904 controls identified two novel loci on 12q24.11-12 (rs6490061, P = 3.20 * 10-8 with an odds ratio [OR] of 0.905) and 20q11.21 (rs2376549, P = 8.11 * 10-10 with an OR of 1.109). rs6490061 is located at intron 19 of the CUX2 gene, and its expression was suppressed by Helicobacter pylori infection. rs2376549 is included within the gene cluster of DEFB families that encode antibacterial peptides. We also found a significant association of rs7849280 in the ABO gene locus on 9q34.2 (P = 2.64 * 10-13 with an OR of 1.148). CUX2 and ABO expression in gastric mucosal tissues was significantly associated with rs6490061 and rs7849280 (P = 0.0153 and 8.00 * 10-11 ), respectively. Our findings show the crucial roles of genetic variations in the pathogenesis of gastric cancer. PMID- 30281875 TI - Phase II clinical trial of S-1 plus nanoparticle albumin-bound paclitaxel in untreated patients with metastatic gastric cancer. AB - The present study is the first phase II clinical trial aimed to evaluate the efficacy and safety of S-1 plus nanoparticle albumin-bound paclitaxel (Nab-PTX) as first-line chemotherapy for advanced gastric cancer (AGC). Previously untreated patients with metastatic gastric adenocarcinoma received S-1 in oral doses of 40 mg (BSA <1.25 m2 ), 50 mg (1.25 <= BSA < 1.50 m2 ) and 60 mg (BSA >=1.50 m2 ) b.i.d. on days 1-14 in combination with Nab-PTX (120 mg/m2 , on days 1 and 8) for each 21-day cycle. Primary endpoint was progression-free survival (PFS), and secondary endpoints were overall response rate (ORR), overall survival (OS), disease control rate (DCR), and toxicity. A total of 73 gastric cancer patients with metastatic and measurable lesions were enrolled in the first-line setting. Median PFS and OS were 9.63 months and 14.60 months, respectively. Four (5.5%) patients had complete responses, 39 (53.4%) had partial responses (PRs), 21 (28.8%) had stable disease, four (5.5%) progressed and five (6.8%) were not evaluable. ORR and DCR were 58.9% and 87.7%, respectively. Most toxicities were mild, and no treatment-related deaths occurred. Grade 3 to 4 toxicities occurred in 22 patients (30.1%) as follows: leukopenia (13.7%), neutropenia (12.3%), anemia (5.5%), thrombocytopenia (1.4%), diarrhea (6.8%), vomiting (2.7%), stomatitis (1.4%), peripheral neuropathy (1.4%), and hand-foot syndrome (1.4%). Seven patients achieved good responses and underwent gastrectomy plus metastasectomy. Thirty (41.1%) patients had S-1 maintenance with a median of four cycles. S-1 plus Nab-PTX is an efficient and safe regimen as first-line treatment for patients with AGC. PMID- 30281879 TI - Heart transplantation for infective endocarditis: Viable option for a limited few? AB - Active infection in the recipient is considered a relative contraindication for solid organ transplantation. However, heart transplantation (HT) can be curative in patients with ventricular assist device infections. For patients with infective endocarditis (IE), valve replacement is part of the management strategy based on emergent, acute, or elective indications. HT has been utilized as an uncommon and sporadic treatment option for carefully selected patients with refractory or recurrent IE after all other surgical treatment options have been exhausted or are not feasible. Herein, we review 19 published cases of IE in whom HT was undertaken in the setting of ongoing active infection with reported good outcomes. We attempt to propose general criteria for HT in the setting of IE and discuss challenges and hurdles that clinicians might encounter when considering HT for active IE in the absence of robust data or clearly defined criteria. PMID- 30281880 TI - Calcium-regulated mitochondrial ATP-Mg/Pi carriers evolved from a fusion of an EF hand regulatory domain with a mitochondrial ADP/ATP carrier-like domain. AB - The mitochondrial ATP-Mg/Pi carrier is responsible for the calcium-dependent regulation of adenosine nucleotide concentrations in the mitochondrial matrix, which allows mitochondria to respond to changing energy requirements of the cell. The carrier is expressed in mitochondria of fungi, plants and animals and belongs to the family of mitochondrial carriers. The carrier is unusual as it consists of three separate domains: (i) an N-terminal regulatory domain with four calcium binding EF-hands similar to calmodulin, (ii) a loop domain containing an amphipathic alpha-helix and (iii) a mitochondrial carrier domain related to the mitochondrial ADP/ATP carrier. This striking example of three domains coming together from different origins to provide new functions represents an interesting quirk of evolution. In this review, we outline how the carrier was identified and how its physiological role was established with a focus on human isoforms. We exploit the sequence and structural information of the domains to explore the similarities and differences to their closest counterparts; mitochondrial ADP/ATP carriers and proteins with four EF-hands. We discuss how their combined function has led to a mechanism for calcium-regulated transport of adenosine nucleotides. Finally, we compare the ATP-Mg/Pi carrier with the mitochondrial aspartate/glutamate carrier, the only other mitochondrial carrier regulated by calcium, and we will argue that they have arisen by convergent rather than divergent evolution.

PMID- 30281881 TI - w-type ions formed by Electron Transfer Dissociation of Cys-containing peptides investigated by infrared ion spectroscopy. AB - In mass spectrometry-based peptide sequencing, Electron Transfer Dissociation (ETD) and Electron Capture Dissociation (ECD) have become well established fragmentation methods complementary to collision-induced dissociation (CID). The dominant fragmentation pathways during ETD and ECD primarily involve the formation of c- and z* -type ions by cleavage of the peptide backbone at the N - Calpha bond, although neutral losses from amino acid side chains have also been observed. Residue-specific neutral side chain losses provide useful information when conducting database searching and de novo sequencing. Here we use a combination of infrared ion spectroscopy and quantum-chemical calculations to assign the structures of two ETD-generated w-type fragment ions. These ions are spontaneously formed from ETD-generated z* -type fragments by neutral loss of 33 Da in peptides containing a cysteine residue. Analysis of the infrared ion spectra confirms that these z* -ions expel a thiol radical (SH* ) and that a vinyl C=C group is formed at the cleavage site. z* -type fragments containing a Cys residue but not at the cleavage site do not spontaneously expel a thiol radical, but only upon additional collisional activation after ETD. PMID- 30281878 TI - p53-inducible gene 3 promotes cell migration and invasion by activating the FAK/Src pathway in lung adenocarcinoma. AB - The p53-inducible gene 3 (PIG3) is one of the p53-induced genes at the onset of apoptosis, which plays an important role in cell apoptosis and DNA damage response. Our previous study reported an oncogenic role of PIG3 associated with tumor progression and metastasis in non-small cell lung cancer (NSCLC). In this study, we further analyzed PIG3 mRNA expression in 504 lung adenocarcinoma (LUAD) and 501 lung squamous cell carcinoma (LUSC) tissues from The Cancer Genome Atlas database and we found that PIG3 expression was significantly higher in LUAD with lymph node metastasis than those without, while no difference was observed between samples with and without lymph node metastasis in LUSC. Gain and loss of function experiments were performed to confirm the metastatic role of PIG3 in vitro and to explore the mechanism involved in its oncogenic role in NSCLC metastasis. The results showed that PIG3 knockdown significantly inhibited the migration and invasion ability of NSCLC cells, and decreased paxillin, phospho focal adhesion kinase (FAK) and phospho-Src kinase expression, while its overexpression resulted in the opposite effects. Blocking FAK with its inhibitor reverses PIG3 overexpression-induced cell motility in NSCLC cells, indicating that PIG3 increased cell metastasis through the FAK/Src/paxillin pathway. Furthermore, PIG3 silencing sensitized NSCLC cells to FAK inhibitor. In conclusion, our data revealed a role for PIG3 in inducing LUAD metastasis, and its role as a new FAK regulator, suggesting that it could be considered as a novel prognostic biomarker or therapeutic target in the treatment of LUAD metastasis. PMID- 30281882 TI - Effectiveness of interventions for unstable patients on antiretroviral therapy in South Africa: results of a cluster-randomised evaluation. AB - BACKGROUND: As loss from HIV care is an ongoing challenge globally, interventions are needed for patients who don't achieve or maintain ART stability. The 2015 South African National Adherence Guidelines (AGL) for Chronic Diseases include two interventions targeted at unstable patients: early tracing of patients who miss visits (TRIC) and enhanced adherence counselling (EAC). METHODS: As part of a cluster-randomised evaluation at 12 intervention and 12 control clinics in four provinces, intervention sites implemented the AGL interventions, while control sites retained standard care. We report on outcomes of EAC for patients with an elevated viral load (>400 copies/ml) and for TRIC patients who missed a visit by >5 days. We estimated risk differences (RD) of 3 and 12-month viral resuppression (<400 copies/ml) and 12-month retention with cluster adjustment using generalised estimating equations and controlled for imbalances using difference-in differences compared to all eligible in 2015, prior to intervention roll-out. RESULTS: For EAC, we had 358 intervention and 505 control site patients (61% female, median ART initiation CD4 count 154 cells/MUl). We found no difference between arms in 3-month resuppression (RD: -1.7%; 95%CI: -4.3% to 0.9%), but <20% of patients had a repeat viral load within 3 months (19.8% intervention, 13.5% control). Including the entire clinic population eligible for EAC with a repeat viral load at all evaluation sites (n = 934), intervention sites showed a small increase in 3-month resuppression (28% vs. 25%, RD 3.0%; 95%CI: -2.7% to 8.8%). Adjusting for baseline differences increased the RD to 8.1% (95% CI: -0.1% to 17.2%). However, we found no differences in 12-month suppression (RD: 1.5%; 95% CI: -14.1% to 17.1% but suppression was low overall at 40%) or retention (RD: 2.8%; 95% CI: -7.5% to 13.2%). For TRIC, we enrolled 155 at intervention sites and 248 at control sites (44% >40 years, 67% female, median CD4 count 212 cells/MUl). We found no difference between groups in return to care by 12 months (RD: -6.8%; 95% CI: -17.7% to 4.8%). During the study period, control sites continued to use tracing within standard care, however, potentially masking intervention effects. CONCLUSIONS: Enhanced adherence counselling showed no benefit over 12 months. Implementation of the tracing intervention under the new guidelines was similar to the standard of care. Interventions that aim to return unstable patients to care should incorporate active monitoring to determine if the interventions are effective. PMID- 30281883 TI - Prostate cancer mortality rates in Peru and its geographical regions. AB - OBJECTIVE: To evaluate the mortality rates for prostate cancer according to geographical areas in Peru between 2005 and 2014. MATERIALS AND METHODS: Information was extracted from the Deceased Registry of the Peruvian Ministry of Health. We analysed age-standardised mortality rates (world population) per 100 000 men. Spatial autocorrelation was determined according to the Moran Index. In addition, we used Cluster Map to explore relations between regions. RESULTS: Mortality rates increased from 20.9 (2005-2009) to 24.1 (2010-2014) per 100 000 men, an increase of 15.2%. According to regions, during the period 2010-2014, the coast had the highest mortality rate (28.9 per 100 000), whilst the rainforest had the lowest (7.43 per 100 000). In addition, there was an increase in mortality in the coast and a decline in the rainforest over the period 2005-2014. The provinces with the highest mortality were Piura, Lambayeque, La Libertad, Callao, Lima, Ica, and Arequipa. Moreover, these provinces (except Arequipa) showed increasing trends during the years under study. The provinces with the lowest observed prostate cancer mortality rates were Loreto, Ucayali, and Madre de Dios. This study showed positive spatial autocorrelation (Moran's I: 0.30, P = 0.01). CONCLUSION: Mortality rates from prostate cancer in Peru continue to increase. These rates are higher in the coastal region compared to those in the highlands or rainforest. PMID- 30281884 TI - Consensus-based Criterion Standard for the Identification of Pediatric Patients Who Need Emergency Medical Services Transport to a Hospital with Higher-level Pediatric Resources. AB - BACKGROUND: Emergency medical services (EMS) providers must be able to identify the most appropriate destination facility when treating children with potentially severe medical illnesses. Currently, no validated tool exists to assist EMS providers in identifying children who need transport to a hospital with higher level pediatric care. For such a tool to be developed, a criterion standard needs to be defined that identifies children who received higher-level pediatric medical care. OBJECTIVE: The objective was to develop a consensus-based criterion standard for children with a medical complaint who need a hospital with higher level pediatric resources. METHODS: Eleven local and national experts in EMS, emergency medicine (EM), and pediatric EM were recruited. Initial discussions identified themes for potential criteria. These themes were used to develop specific criteria that were included in a modified Delphi survey, which was electronically delivered. The criteria were refined iteratively based on participant responses. To be included, a criterion required at least 80% agreement among participants. If an item had less than 50% agreement, it was removed. A criterion with 50% to 79% agreement was modified based on participant suggestions and included on the next survey, along with any new suggested criteria. Voting continued until no new criteria were suggested and all criteria received at least 80% agreement. RESULTS: All 11 recruited experts participated in all seven voting rounds. After the seventh vote, there was agreement on each item and no new criteria were suggested. The recommended criterion standard included 13 items that apply to patients 14 years old or younger. They included IV antibiotics for suspicion of sepsis or a seizure treated with two different classes of anticonvulsive medications within 2 hours, airway management, blood product administration, cardiopulmonary resuscitation, electrical therapy, administration of specific IV/IO drugs or respiratory assistance within 4 hours, interventional radiology or surgery within 6 hours, intensive care unit admission, specific comorbid conditions with two or more abnormal vital signs, and technology-assisted children seen for device malfunction. CONCLUSION: We developed a 13-item consensus-based criterion standard definition for identifying children with medical complaints who need the resources of a hospital equipped to provide higher-level pediatric services. This criterion standard will allow us to create a tool to improve pediatric patient care by assisting EMS providers in identifying the most appropriate destination facility for ill children. PMID- 30281885 TI - CdSe/CdS Dot-in-Rods Nanocrystals Fast Blinking Dynamics. AB - Analyzing the autocorrelation function of the fluorescence intensity, we demonstrate that these nanoemitters are characterized by a short value of the mean duration of bright periods (ten to a few hundreds of microseconds). The comparison of the results obtained for samples with different geometries shows that not only the shell thickness is crucial but also the shape of the dot-in rods. Increasing the shell aspect ratio results in shorter bright periods suggesting that surface traps impact the stability of the fluorescence intensity. PMID- 30281886 TI - Association between lower urinary tract symptoms and cardiovascular risk scores in ostensibly healthy women. AB - OBJECTIVES: To investigate the association between lower urinary tract symptoms (LUTS) and cardiovascular disease (CVD) risk in women, as severe LUTS are known to be associated with CVD risk in men but few studies have focused on this issue in women. SUBJECTS AND METHODS: A total of 1014 ostensibly healthy women, who participated in a voluntary health check in a health promotion centre from November 2013 to October 2015, were enrolled. LUTS were assessed using the International Prostate Symptom Score (IPSS) and Overactive Bladder Symptom Score (OABSS). CVD risk scores were calculated using the Framingham risk score and the American College of Cardiology/American Heart Association Atherosclerotic Cardiovascular Disease (ASCVD) score. Correlation, partial correlation, and multiple logistic regression analyses were conducted. RESULTS: The mean age and body mass index (BMI) of the women were 51 years and 22.6 kg/m2 , respectively. The ASCVD score showed significant positive correlations with IPSS items Question 2 (Q2), Q3, Q5, and Q7 (all P < 0.05), total IPSS (P = 0.001), IPSS storage (P = 0.006) and IPSS voiding symptoms scores (P = 0.001) based on partial correlation analysis after adjustment for BMI. For the OABSS, the ASCVD score showed significant positive correlations with OABSS items Q2, Q3, and Q4 (P < 0.001, P = 0.017, and P < 0.001, respectively) and total OABSS (P < 0.001). Multiple logistic regression analysis showed that the moderate-severe risk groups of the OABSS and IPSS were associated with the ASCVD risk score in adjusted models (P < 0.001) compared to the none-mild OABSS and mild IPSS groups. After adjustment for age and BMI, IPSS storage score was significantly related with the ASCVD risk score (B = 0.855, P = 0.016) CONCLUSIONS: LUTS, especially storage symptoms, might be risk factors for predicting future CVD risk in women. Further prospective or cohort studies are needed to validate this possibility. PMID- 30281887 TI - DNA repair defects in prostate cancer: impact for screening, prognostication and treatment. AB - Failure of effective DNA damage repair is a hallmark of cancer, but was previously underappreciated as a driver of aggressive prostate cancer. However, recent international sequencing efforts have revealed that both germline and somatic alterations within the homologous recombination and mismatch repair pathways are relatively common in lethal metastatic disease. BRCA2 gene alterations are particularly prevalent and are linked to poor prognosis as well as poor responses to systemic therapy for castration-resistant prostate cancer, although there is conflicting support for the latter. Defective DNA repair contributes to tumour heterogeneity, evolution and progression, but there are high hopes that management of this aggressive subset will be transformed by biomarker-driven use of poly-ADP ribose polymerase (PARP) inhibitors and platinum based chemotherapy. In this review, we detail the relationship between DNA repair defects and prostate cancer, highlighting the prevalence of mutations in key genes and their controversial association with clinical outcomes. PMID- 30281888 TI - Sphingosine-1-phosphate protects against brain microvascular endothelial junctional protein disorganization and barrier dysfunction caused by alcohol. AB - OBJECTIVE: S1P has known endothelial barrier-protective properties, but whether this extends to the BBB is unclear. We hypothesized that alcohol-induced disruption of brain microvascular endothelial barrier function and junctional protein organization can be ameliorated by S1P treatment. METHODS: Cultured primary HBMEC monolayers were used to characterize endothelial-specific mechanisms of BBB regulation. TER and apparent permeability coefficients for albumin, dextran-4 kDa, and sodium fluorescein were used as indices of barrier function. Junctional localization of Claudin-5, VE-cadherin, and beta-catenin was determined by immunofluorescence confocal microscopy. S1P was applied following treatment with alcohol. RESULTS: Alcohol significantly impaired HBMEC TER. Application of S1P after alcohol treatment resulted in a hastened recovery to the baseline HBMEC TER. Alcohol-treated HBMEC had a significantly higher mean permeability than control that was reversed by S1P. Alcohol caused the formation of gaps between cells. Treatment with S1P (after alcohol) increased junctional localization of VE-Cadherin, Claudin-5, and beta-catenin. CONCLUSIONS: Alcohol impairs the barrier function and junctional organization of HBMEC monolayers. S1P enhanced barrier function and restored junctions in the presence of alcohol, and thus may be useful for restoring BBB function during alcohol intoxication. PMID- 30281889 TI - Active K-RAS induces the coherent rotation of epithelial cells: A model for collective cell invasion in vitro. AB - At the invasive front of adenocarcinomas, single cells and multicellular structures exist; the latter include glands and cell clusters, such as tumor buddings and poorly differentiated clusters. Recent reports suggest the importance of collective cell migration in metastasis; however, it is technically difficult to observe the movement of multicellular structures in vivo. We utilized MDCK cells as a model for epithelial cells and established a method to quantify their motility in 3D structures in vitro. A single MDCK cell grows as a cell cluster in the gel and later proliferates and forms a cyst. Active K-RAS expression induced rotation of both the cell clusters and the cysts. The rotation speed of cell clusters was 4 times higher than that of cysts. The screening of inhibitors for their effects on cell clusters and cysts revealed that cyclin B1 and beta-catenin were the key molecules for their rotation, respectively. Regulators for cyst rotation, such as vorinostat and beta-catenin, were not effective for inducing cell cluster rotation. These results indicate that the signaling pathways of cell dynamics are different between cell clusters and cysts. As cell clusters are related to lymph node involvement and the prognosis of various carcinomas, our in vitro quantitative system may be useful for the screening of drugs to prevent lymphatic invasion. PMID- 30281890 TI - Chemical cross-linking of a variety of green fluorescent proteins as Forster resonance energy transfer donors for Yukon orange fluorescent protein: A project based undergraduate laboratory experience. AB - Forster resonance energy transfer (FRET) is the basis for many techniques used in biomedical research. Due to its wide use in molecular sensing, FRET is commonly introduced in many biology, chemistry, and physics courses. While FRET is of great importance in the biophysical sciences, the complexity and difficulty of constructing FRET experiments has resulted in limited usage in undergraduate laboratory settings. Here, we present a practical undergraduate laboratory experiment for teaching FRET using a diverse set of green-emitting fluorescent proteins (FPs) as donors for a cross-linked Yukon orange FP. This laboratory experiment enables students to make the connection of basic lab procedures to real world applications and can be applied to molecular biology, biochemistry, physical chemistry, and biophysical laboratory courses. Published 2018. This article is a U.S. Government work and is in the public domain in the USA., 46(5):516-522, 2018. PMID- 30281891 TI - A metabolic control analysis approach to introduce the study of systems in biochemistry: the glycolytic pathway in the red blood cell. AB - Metabolic control analysis (MCA) is a promising approach in biochemistry aimed at understanding processes in a quantitative fashion. Here the contribution of enzymes and transporters to the control of a given pathway flux and metabolite concentrations is determined and expressed quantitatively by means of numerical coefficients. Metabolic flux can be influenced by a wide variety of modulators acting on one or more metabolic steps along the pathway. We describe a laboratory exercise to study metabolic regulation of human erythrocytes (RBCs). Within the framework of MCA, students use these cells to determine the sensitivity of the glycolytic flux to two inhibitors (iodoacetic acid: IA, and iodoacetamide: IAA) known to act on the enzyme glyceraldehyde-3-phosphate-dehydrogenase. Glycolytic flux was estimated by determining the concentration of extracellular lactate, the end product of RBC glycolysis. A low-cost colorimetric assay was implemented, that takes advantage of the straightforward quantification of the absorbance signal from the photographic image of the multi-well plate taken with a standard digital camera. Students estimate flux response coefficients for each inhibitor by fitting an empirical function to the experimental data, followed by analytical derivation of this function. IA and IAA exhibit qualitatively different patterns, which are thoroughly analyzed in terms of the physicochemical properties influencing their action on the target enzyme.

AB - BACKGROUND: To provide feedback to surgeons in robotic surgery training, many surgical skill evaluation methods have been developed. However, they hardly focus on the performance of the surgical motion segments. This paper proposes a method of specifying a trainee's skill weakness in the surgical training. METHODS: This paper proposed an automatic skill evaluation framework by comparing the trainees' operations with the template operation in each surgical motion segment, which is mainly based on dynamic time warping (DTW) and continuous hidden Markov model (CHMM). RESULTS: The feasibility of this proposed framework has been preliminarily verified. For specifying the skill weakness in instrument handling and efficiency, the result of this proposed framework was significantly correlated with that of manual scoring. CONCLUSION: The automatic skill evaluation framework has shown its superiority in efficiency, objectivity, and being targeted, which can be used in robotic surgery training. PMID- 30281893 TI - Effect of blue-light cystoscopy on contemporary performance of urine cytology. AB - OBJECTIVE: To evaluate the performance of urine cytology based on contemporary data, including the effect of enhanced cystoscopic techniques. MATERIALS AND METHODS: Individual patient data were obtained from three prospective studies: the Photocure (PC) B305 and the PC B308 studies, evaluating the use of blue-light cystoscopy with hexaminolevulinate (BLC-H), and the Cxbladder monitoring study, evaluating the Cxbladder monitor test for the detection of recurrent urothelial carcinoma. The specificity and sensitivity of cytology in each study and for the overall cohort were calculated. RESULTS: A total of 1 487 urine samples from 1 375 patients were included in the analysis; overall 615 tumours were detected correlating to 41% of the cytological specimens. The pooled sensitivity and specificity for cytology were 40.8% and 92.8%, respectively. The pooled sensitivity was 11.4% for low-grade/World Health Organization (WHO) grade 1 disease and 54.3% for high-grade/WHO grade 3 disease. There were no differences in cytology sensitivity based on the type of cystoscopy used, with sensitivity of 41.3% and 40.4% in white-light cystoscopy (WLC) and BLC-H, respectively. Subgroup analysis including carcinoma in situ ( CIS) showed a trend towards lower cytology sensitivity in BLC-H (54.5%) vs WLC (69.2%). CONCLUSIONS: Based on analysis of contemporary data, the sensitivity of cytology for detecting high-grade tumours and CIS remains low. On a per-patient analysis, cytology sensitivity was not affected by the use of advanced cystoscopic techniques except in patients with CIS. The use of cytology as the main adjunct to cystoscopy in patients at high risk can lead to missed opportunities for early detection of recurrence and for determining which patients are not responding to intravesical therapies such as bacille Calmette-Guerin. PMID- 30281894 TI - Physical models can provide superior learning opportunities beyond the benefits of active engagements. AB - The essence of molecular biology education lies in understanding of gene expression, with subtopics including the central dogma processes, such as transcription and translation. While these concepts are core to the discipline, they are also notoriously difficult for students to learn, probably because they cannot be directly observed. While nearly all active learning strategies have been shown to improve learning compared with passive lectures, little has been done to compare different types of active learning. We hypothesized that physical models of central dogma processes would be especially helpful for learning, because they provide a resource that students can see, touch, and manipulate while trying to build their knowledge. For students enrolled in an entirely active-learning-based Cell & Molecular Biology course, we examined whether model based activities were more effective than non-model based activities. To test their understanding at the beginning and end of the semester, we employed the multiple-select Central Dogma Concept Inventory (CDCI). Each student acted as their own control, as all students engaged in all lessons yet some questions related to model-based activities and some related to clicker questions, group problem-solving, and other non-model-based activities. While all students demonstrated learning gains on both types of question, they showed much higher learning gains on model-based questions. Examining their selected answers in detail showed that while higher performing students were prompted to refine their already-good mental models to be even better, lower performing students were able to construct new knowledge that was much more consistent with an expert's understanding.

PMID- 30281895 TI - Changing trends in the endourological management of urolithiasis in anomalous kidneys. AB - OBJECTIVES: To present our single-centre experience of urolithiasis management in anomalous kidneys, highlighting the need for an algorithm-based approach in deciding the appropriate treatment method for each type. PATIENTS AND METHODS: We retrospectively reviewed the data of all the patients who presented to our renal unit with urolithiasis in an anomalous kidney between January 1990 and July 2014. The peri-operative characteristics of all the patients, along with management approach, were studied. RESULTS: Percutaneous nephrolithotomy (PCNL) was the most common surgical technique used, followed by flexible ureterorenoscopy (URS). Pain was the most common presentation in these patients. The overall stone clearance rate associated with PCNL and flexible URS was 85.8% in cases of anomalous kidneys in this series. The stone clearance rates in ectopic kidneys, horseshoe kidneys, malrotated kidneys and autosomal dominant polycystic kidneys associated with PCNL and flexible URS were similar: 86%, 88%, 76% and 83%, respectively, and 81.2%, 80%, 92% and 100%, respectively . Based on our results, we developed a stone management algorithm. CONCLUSION: The management of renal calculi in patients with renal anomalies may vary based on the stone size, location, density, pelvicalyceal system anatomy and drainage. An algorithm-based approach could help surgeons decide the appropriate treatment in this population.

AB - Although continued use of antidepressants (AD) has been found to be associated with a lower risk of suicide, AD discontinuation is reported repeatedly. The aim of this case-control study, thus, was to assess whether discontinuation to AD was associated with an increased risk of suicide, according to different genders and age groups. The Social and Health Information System of Friuli Venezia Giulia Region, Italy, was used to collect data on suicides, diagnoses and AD use from 2005 to 2014. We selected, as cases, all suicides that had at least one prescription of AD in the 730 days before death (N = 876), and we matched with regard to age and sex each case with five controls from the general population. Conditional logistic regression analyses were used to assess the association between suicide and modifications of AD treatment. We found that 70% of suicides and controls from the general population discontinued AD in the 2 years before the index date. In two-thirds of them, discontinuations were two or more. Discontinuation of AD, however, did not represent a significant risk factor for suicide. More appropriate care of depression, particularly by primary care physicians who widely prescribe AD, should be fostered in order to prevent suicide. However, more research is needed to assess to which extent AD discontinuation can affect suicidal risk.

AB - Contemporary mental health policies call for increased involvement of consumers in leadership across mental health service design, delivery, and evaluation. However, consumer leadership is not currently well understood within academia or in mental health services themselves. This study investigates how consumer leadership is currently conceptualized by stakeholders at the service delivery level. To this end, semistructured interviews were conducted with 14 mental health organization members identifying as consumer leaders, colleagues supporting consumer leaders, or organization executives. Interview data were analysed using an inductive thematic analysis to develop a broad understanding of participants' perceptions of consumer leadership. Findings indicate constructions of consumer leadership within mental health organizations can be understood in relation to four themes: consumer leadership roles, requirements, purpose, and process. Inconsistencies across participants' perceptions of consumer leadership were identified as constituting barriers to its development, highlighting the need to better clarify the nature of consumer leadership. PMID- 30281899 TI - A novel patient-specific three-dimensional drug delivery construct for regenerative endodontics. AB - Evoked bleeding (EB) clinical procedure, comprising a disinfection step followed by periapical tissue laceration to induce the ingrowth of undifferentiated stem cells from the periodontal ligament and alveolar bone, is currently the only regenerative-based therapeutic approach to treating pulp tissue necrosis in undeveloped (immature) permanent teeth approved in the United States. Yet, the disinfection step using antibiotic-based pastes leads to cytotoxic, warranting a biocompatible strategy to promote root canal disinfection with no or minimal side effects to maximize the regenerative outcomes. The purpose of this investigation was to develop a tubular three-dimensional (3D) triple antibiotic-eluting construct for intracanal drug delivery. Morphological (scanning electron microscopy), chemical (Fourier transform infrared spectroscopy), and mechanical (tensile testing) characteristics of the polydioxanone-based triple antibiotic eluting fibers were assessed. The antimicrobial properties of the tubular 3D constructs were determined in vitro and in vivo using an infected (Actinomyces naeslundii) dentin tooth slice model and a canine method of periapical disease, respectively. The in vitro data indicated significant antimicrobial activity and the ability to eliminate bacterial biofilm inside dentinal tubules. In vivo histological findings demonstrated that, using the EB procedure, the tubular 3D triple antibiotic-eluting construct allowed the formation of an appropriate environment that led to apex closure and the ingrowth of a thin layer of osteodentin-like tissue into the root canal. Taken together, these findings indicate that our novel drug delivery construct is a promising biocompatible disinfection strategy for immature permanent teeth with necrotic pulps.

AB - Eradication of cancer stem-like cells (CSLCs) are becoming increasingly an important target for new cancer therapies. The ability to study their behavior in vitro will provide the opportunity for high-throughput testing of more effective treatments. In this study, spheroid-like structures' formation and enrichment of HT29 CSLCs were evaluated on a wool keratin-based substrate as a bio-mimic of natural extracellular matrix (ECM) proteins. The results indicated that culturing on keratin substrate increased spheroid formation ability and radio /chemoresistance of HT29 cells. Moreover, cell surface expression of CD133 CSLCs' marker and the mRNA level of stemness genes such as Nanog, Oct4, and c-MYC were increased. These data suggest that keratin can potentially be used for spheroid like structure formation and enrichment of HT29 CSLCs. In addition, it seems that the induction of stemness characteristics on keratin substrate is probably because of the activation of alpha2 beta1 integrin signaling pathway.

PMID- 30281902 TI - A combined lipidomic and 16S rRNA gene amplicon sequencing approach reveals archaeal sources of intact polar lipids in the stratified Black Sea water column. AB - Archaea are important players in marine biogeochemical cycles, and their membrane lipids are useful biomarkers in environmental and geobiological studies. However, many archaeal groups remain uncultured and their lipid composition unknown. Here, we aim to expand the knowledge on archaeal lipid biomarkers and determine the potential sources of those lipids in the water column of the euxinic Black Sea. The archaeal community was evaluated by 16S rRNA gene amplicon sequencing and by quantitative PCR. The archaeal intact polar lipids (IPLs) were investigated by ultra-high-pressure liquid chromatography coupled to high-resolution mass spectrometry. Our study revealed both a complex archaeal community and large changes with water depth in the IPL assemblages. In the oxic/upper suboxic waters (<105 m), the archaeal community was dominated by marine group (MG) I Thaumarchaeota, coinciding with a higher relative abundance of hexose phosphohexose crenarchaeol, a known marker for Thaumarchaeota. In the suboxic waters (80-110 m), MGI Nitrosopumilus sp. dominated and produced predominantly monohexose glycerol dibiphytanyl glycerol tetraethers (GDGTs) and hydroxy-GDGTs. Two clades of MGII Euryarchaeota were present in the oxic and upper suboxic zones in much lower abundances, preventing the detection of their specific IPLs. In the deep sulfidic waters (>110 m), archaea belonging to the DPANN Woesearchaeota, Bathyarchaeota, and ANME-1b clades dominated. Correlation analyses suggest that the IPLs GDGT-0, GDGT-1, and GDGT-2 with two phosphatidylglycerol (PG) head groups and archaeol with a PG, phosphatidylethanolamine, and phosphatidylserine head groups were produced by ANME-1b archaea. Bathyarchaeota represented 55% of the archaea in the deeper part of the euxinic zone and likely produces archaeol with phospho-dihexose and hexose-glucuronic acid head groups. PMID- 30281903 TI - A mitochondrial ROS pathway controls matrix metalloproteinase 9 levels and invasive properties in RAS-activated cancer cells. AB - Matrix metalloproteinases (MMPs) are tissue-remodeling enzymes involved in the processing of various biological molecules. MMPs also play important roles in cancer metastasis, contributing to angiogenesis, intravasation of tumor cells, and cell migration and invasion. Accordingly, unraveling the signaling pathways controlling MMP activities could shed additional light on cancer biology. Here, we report a molecular axis, comprising the molecular adaptor hydrogen peroxide inducible clone-5 (HIC-5), NADPH oxidase 4 (NOX4), and mitochondria-associated reactive oxygen species (mtROS), that regulates MMP9 expression and may be a target to suppress cancer metastasis. We found that this axis primarily downregulates mtROS levels which stabilize MMP9 mRNA. Specifically, HIC-5 suppressed the expression of NOX4, the source of the mtROS, thereby decreasing mtROS levels and, consequently, destabilizing MMP9 mRNA. Interestingly, among six cancer cell lines, only EJ-1 and MDA-MB-231 cells exhibited upregulation of NOX4 and MMP9 expression after shRNA-mediated HIC-5 knockdown. In these two cell lines, activating RAS mutations commonly occur, suggesting that the HIC-5 mediated suppression of NOX4 depends on RAS signaling, a hypothesis that was supported experimentally by the introduction of activated RAS into mammary epithelial cells. Notably, HIC-5 knockdown promoted lung metastasis of MDA-MB-231 cancer cells in mice. The tumor growth of HIC-5-silenced MDA-MB-231 cells at the primary sites was comparable to that of control cells. Consistently, the invasive properties of the cells, but not their proliferation, were enhanced by the HIC-5 knockdown in vitro. We conclude that NOX4-mediated mtROS signaling increases MMP9 mRNA stability and affects cancer invasiveness but not tumor growth. PMID- 30281904 TI - Dosage and composition of bioactive glasses differentially regulate angiogenic and osteogenic response of human MSCs. AB - Vascularization of the fracture site and cell-mediated deposition of the mineralized matrix are crucial determinants for successful bone regeneration after injury. Ceramic biomaterials such as bioactive glasses (BAGs) that release bioactive ions have shown promising results in bone defect regeneration. However, it remains unclear how the dosage and composition of bioactive ions influence the angiogenic and osteogenic behavior of primary human mesenchymal stromal cells (MSCs). Here, we show that exposure to ionic dissolution products from 1393 and 45S5 BAGs can evoke distinct angiogenic and osteogenic responses from primary MSCs in a dose- and composition-dependent manner. Significantly higher concentrations of the pro-angiogenic factors VEGF, HGF, PIGF, angiopoietin, and angiogenin were detected in conditioned media (CM) from MSCs exposed to 45S5, but not 1393, BAGs. Application of this CM to human umbilical vein endothelial cells (HUVECs) resulted in robust 2D tube formation in vitro. Osteogenic differentiation of MSCs was assessed by gene expression analysis and mineralization assays. Low concentrations (0.1% w/v) of 1393 BAGs significantly enhanced the gene expression of RUNX2 and ALP and induced an earlier onset of matrix mineralization compared to all other groups. We further tested whether simultaneous exposure to both BAGs would improve both angiogenic secretion and osteogenic differentiation of MSCs, and did not find evidence to support this hypothesis. Our results provide evidence of BAG composition-dependent enhancement of primary human MSCs' regenerative function, besides also underlining the importance of an in vitro evaluation of the dose-response relationship to translate BAG based approaches into safe and effective clinical therapies.

PMID- 30281905 TI - Development of novel PLGA nanoparticles with co-encapsulation of docetaxel and abiraterone acetate for a highly efficient delivery into tumor cells. AB - Co-encapsulation of abiraterone acetate (AbrA) and docetaxel (Dtx) in polymeric nanoparticles as novel prototypes for prostate cancer treatment combining hormonal and chemotherapy was designed. Nanoparticles (NPs) composed of poly(dl lactide-co-glycolide) (PLGA) were prepared by single-emulsion solvent evaporation technique and characterized in terms of morphology with atomic force microscopy and transmission electron microscopy. HPLC method for simultaneous determination of AbrA and Dtx encapsulation efficacy was developed. Also differential scanning calorimetry and Fourier-transform infrared spectroscopy were provided. To study the effectiveness of cellular internalization and distribution of NPs with AbrA and Dtx co-encapsulation (NP-AbrA/Dtx), a fluorescence microscopy was utilized. NPs prepared had size 256.3 +/-9.4 nm and zeta potential -18.4 +/-1.4 mV. Encapsulation efficacy for AbrA was 68.7% and for Dtx was 74.3%. NPs were able to control the AbrA and Dtx release within 24 h. The mathematical model of drug release was performed. The results obtained from confocal microscopy showed the effective accumulation of the NP-AbrA/Dtx in the cytoplasm of cells. Synthesized NPs possessed satisfactory parameters and a biphasic release profile, proceeding by the Fick diffusion mechanism, which provide prolonged release of the drugs and maintenance of their concentration. It was shown that NPs loaded with AbrA and Dtx exhibited a high cytotoxic activity on the LNCaP cell line, similar to the combination of free drugs of AbrA and Dtx, but in contrast to the combination of substances, had a synergistic mechanism of action. Our findings support the potential use of developed NPs in further in vivo studies. (c) 2018 Wiley Periodicals, Inc. J Biomed Mater Res Part B, 2018. PMID- 30281906 TI - Monolithic thin-layer chromatography plates with covalently bonded matrix for hyphenation with matrix-assisted laser desorption/ionization. AB - Monolithic layers prepared by the copolymerization of ethylene dimethacrylate and glycidyl methacrylate and deposited onto the surface of glass and silicon plates were investigated as thin-layer chromatography separation media in hyphenated thin-layer chromatography with matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) analysis. Varying composition of the polymerization mixture and polymerization conditions layers of different porosities and MALDI-MS compatibility were synthesized. Compatibility with MALDI-MS was tested using polyethylene glycol and it was demonstrated that layers prepared without glycidyl methacrylate are not compatible with MALDI-MS and do not allow obtaining any mass spectra. Best results were achieved with layers containing 19 to 29% glycidyl methacrylate. These layers allow the measurement of mass spectra without additional depositing matrix compounds supplying mass spectra almost "clean" in low molar mass range. PMID- 30281907 TI - Novel applications of nonwood cellulose for blood typing assays. AB - Paper-based microfluidics devices can create a new healthcare model. Cellulose is carbohydrate polymer biocompatible and hydrophilic. These characteristics enhance the development of user-friendly diagnostic devices, but the link between paper manufacturing process and performance of the devices is still unclear. Previous studies focused on either commercial papers or lab papers from wood-cellulose fibers, with different basis-weight. This work introduces the effect of refining process and lab paper from nonwood-cellulose fibers, focusing on sisal fibers to overcome the aforementioned challenge. Structural characteristics of paper, such as basis-weight and degree of refining, are optimized and correlated with blood typing test resolution. Unrefined sisal paper of 50 g/m2 and 100 g/m2 basis weight exhibit a higher gray intensity level than refined paper, and also maximal capillary rise and a pore size suitable for blood grouping tests. Two different blood types were evaluated with results consistent with the traditional methods, testifying the usefulness of this methodology. (c) 2018 Wiley Periodicals, Inc. J. Biomed. Mater. Res.

AB - Indocyanine green (ICG) is the only FDA-approved near-infrared dye and it is currently used clinically for diagnostic applications. However, there is significant interest in using ICG for triggered drug delivery applications and heat ablation therapy. Unfortunately, free ICG has a short half-life in vivo and is rapidly cleared from circulation. Liposomes have been frequently used to improve ICG's stability and overall time of effectiveness in vivo, but they have limited stability due to the susceptibility of phospholipids to hydrolysis and oxidation. In this study, nonphospholipid liposomes were used to encapsulate ICG, and the resulting liposomes were characterized for size, encapsulation efficiency, stability, and photothermal response. Using the thin-film hydration method, an ICG encapsulation efficiency of 54% was achieved, and the liposomes were stable for up to 12 weeks, with detectable levels of encapsulated ICG up to week 4. Additionally, ICG-loaded liposomes were capable of rapidly producing a significant photothermal response upon exposure to near-infrared light, and this photothermal response was able to induce changes in the mechanical properties of thermally responsive hydrogels.

AB - The cellobiohydrolase (CBH) Cel6A is an important component of enzyme cocktails for industrial degradation of lignocellulosic biomass. However, the kinetics of this enzyme acting on its natural, insoluble substrate remains sparsely investigated. Here, we studied Cel6A from Trichoderma reesei with respect to adsorption, processivity, and kinetics both in the steady-state and pre-steady state regimes, on microcrystalline and amorphous cellulose. We found that slow dissociation (koff ) was limiting the overall reaction rate, and we suggest that this leads to an accumulation of catalytically inactive complexes in front of obstacles and irregularities on the cellulose surface. The processivity number of Cel6A was low on both investigated substrates (5-10), and this suggested a rugged surface with short obstacle-free path lengths. The turnover of the inner catalytic cycle (the reactions of catalysis in one processive step) was too fast to be fully resolved, but a minimum value of about 20 s-1 could be established. This is among the highest values reported hitherto for a cellulase, and it underscores the catalytic efficiency of Cel6A. Conversely, we found that Cel6A had a poor ability to recognize attack sites on the cellulose surface. On amorphous cellulose, for example, Cel6A was only able to initiate hydrolysis on about 4% of the sites to which it could adsorb. This probably reflects high requirements of Cel6A to the architecture of the site. We conclude that compared to the other CBH, Cel7A, secreted by T. reesei, Cel6A is catalytically more efficient but less capable of attacking a broad range of structurally distinct sites on the cellulose surface. ENZYMES: TrCel6A, nonreducing end-acting cellobiohydrolase (EC3.2.1.91) from Trichoderma reesei; TrCel7A, reducing end acting cellobiohydrolase (EC3.2.1.176) from T. reesei. PMID- 30281910 TI - Molecular phylogenetics of Newcastle disease viruses isolated from vaccinated flocks during outbreaks in Southern India reveals circulation of a novel sub genotype. AB - Newcastle disease (ND) is an economically important, contagious poultry viral disease reported across the globe. In India, ND is endemic and episodes of ND outbreaks despite strict vaccinations are not uncommon. We isolated and characterized seven ND viruses from vaccinated commercial poultry farms during severe disease outbreaks in Tamil Nadu, in Southern India, between April 2015 and June 2016. All the seven isolates were categorized as virulent by mean death time (48-54 hr) in embryonated chicken eggs. Also, their sequences carried the virulence signature of multi-basic amino acid residues in their fusion protein cleavage site (RRQ/RR/KRF). Phylogenetic and evolutionary distance analyses revealed circulation of a novel sub-genotype of genotype XIII, class II ND viruses, herein proposed as sub-genotype XIIIe. The genetic divergence between the circulating virulent strains and the vaccine strains could possibly explain the disease outbreak in the vaccinated flocks. Further, our study signifies the need to implement routine epidemiological surveillance and to revisit the current vaccination program. PMID- 30281911 TI - Does mitochondrial DNA evolution in metazoa drive the origin of new mitochondrial proteins? AB - Most eukaryotic cells contain mitochondria with a genome that evolved from their alpha-proteobacterial ancestor. In the course of eukaryotic evolution, the mitochondrial genome underwent a dramatic reduction in size, caused by the loss and translocation of genes. This required adjustments in mitochondrial gene expression mechanisms and resulted in a complex collaborative system of mitochondrially encoded transfer RNAs and ribosomal RNAs with nuclear encoded proteins to express the mitochondrial encoded oxidative phosphorylation (OXPHOS) proteins. In this review, we examine mitochondrial gene expression from an evolutionary point of view: to what extent can we correlate changes in the mitochondrial genome in the evolutionary lineage leading to human with the origin of new nuclear encoded proteins. We dated the evolutionary origin of mitochondrial proteins that interact with mitochondrial DNA or its RNA and/or protein products in a systematic manner and compared them with documented changes in the mitochondrial DNA. We find anecdotal but accumulating evidence that metazoan RNA-interacting proteins arose in conjunction with changes of the mitochondrial DNA. We find no substantial evidence for such compensatory evolution in new OXPHOS proteins, which appear to be constrained by the ability to form supercomplexes.

AB - Our earlier work has shown that the E3 ligase TRIM56 messenger RNA (mRNA) level and vimentin protein expression followed an inverse correlation in ovarian carcinoma patients; however, the regulatory mechanisms underlying TRIM56 expression is unclear. Steady state expression of TRIM56 mRNA expression in the normal ovarian cell line Moody and ovarian cancer cell lines SKOV-3, A2780, and Caov-3 were not significantly different; however, TRIM56 protein expression was significantly lower in the ovarian cancer cell lines compared to the Moody cell line. Polysome profiling showed significant increase in translation of TRIM56 messenger RNA in the Moody cells compared to the SKOV-3 cells. We performed RNA affinity pulldown using biotinylated TRIM56 5 'and 3'-UTR and postnuclear extracts from Moody and SKOV-3 cells. Whereas no notable difference was observed in affinity pull-down obtained with the 5'-UTR, there was obvious difference in protein binding patterns with the 3'-UTR. Mass spectrometry was used to determine the most differentially binding protein as poly r (c) binding protein 1 (PCBP1). PCBP1 expression and binding to the 3'-UTR was both higher in SKOV-3 cells compared to the Moody cells. Silencing of TRIM56 in Moody cells cause an increase in in vitro migration and invasion, and a similar effect was mimicked by overexpression of PCBP1. Conversely, silencing of PCBP1 or overexpression of TRIM56 in SKOV-3 cells significantly decreased in vitro migration and invasion. In xenograft assays, SKOV-3 cells stably overexpressing shRNA targeting PCBP1 decreased metastasis, whereas shRNA-targeting TRIM56 potentiated detection of metastatic lesions, compared to the parental SKOV-3 cells themselves. Taken together our results reveal a yet undefined posttranscriptional regulatory mechanism underlying low expression of TRIM56 in ovarian cancer. (c) 2018 IUBMB Life, 9999(9999):1-6, 2018. PMID- 30281914 TI - Up-regulation and tumor-promoting role of SPHK1 were attenuated by miR-330-3p in gastric cancer. AB - We intended to clarify the role of sphingosine kinase 1 (SPHK1) in gastric cancer (GC) using both in vitro and in vivo assays. The study was designed to identify novel therapeutic targets for GC treatment. Differential analysis was utilized to dissect two gene expression omnibus series (GSE49515 and GSE79973) microarray data form Gene Expression Omnibus (GEO) (https://www.ncbi.nlm.nih.gov/geo/) dataset. MRNA and protein expressions were determined by quantitative polymerase chain reaction and Western blot, respectively. GC cell growth was measured by MTT assays and verified by in vivo analysis. Cell cycle and cell apoptosis were detected via flow cytometer observation. Cell migration and invasion were assessed by wound healing assays and Transwell assays. The targeting relationship between miRNA and SPHK1/S1PR1 was identified via dual-luciferase assay. Twenty four common differentially expressed genes were screened out from two gene expression omnibus series (GSE49515 and GSE79973), among which SPHK1 was chosen for its higher fold change. We found elevated SPHK1 expression in GC tissues and cells, along with an increased concentration of SPHK1-generated sphingosine-1 phosphate (S1P) in both GC serum and tissue. SPHK1 knockdown significantly suppressed cell proliferation, migration, and invasion of MKN1 and KATO3 cells. It also blocked cell cycle and induced apoptosis in MKN1 and KATO3 cells. Silencing of SPHK1 also refrained tumor growth and inhibited S1P level. MiR-330 3p directly targeted SPHK1 and S1PR1. Overexpressed miR-330-3p in MKN1 cells repressed SPHK1 and S1PR1 expressions like their chemical inhibitors-SPHK1 inhibitors (FTY720) and S1PR1 inhibitors (VPC23019), and acted anti-tumor both in vitro and in vivo. Our study provides evidence that SPHK1 was promotive for GC tumor growth and cell biological behaviors, and that miR-330-3p targeted 3'-UTR of SPHK1 and inhibited its expression. SPHK1 was expected to become a new molecular marker and miR-330-3p a novel therapeutic target for GC. (c) 2018 IUBMB Life, 70(11):1164-1176, 2018. PMID- 30281913 TI - An improved method for utilizing high-throughput amplicon sequencing to determine the diets of insectivorous animals. AB - DNA analysis of predator feces using high-throughput amplicon sequencing (HTS) enhances our understanding of predator-prey interactions. However, conclusions drawn from this technique are constrained by biases that occur in multiple steps of the HTS workflow. To better characterize insectivorous animal diets, we used DNA from a diverse set of arthropods to assess PCR biases of commonly used and novel primer pairs for the mitochondrial gene, cytochrome oxidase C subunit 1 (COI). We compared diversity recovered from HTS of bat guano samples using a commonly used primer pair "ZBJ" to results using the novel primer pair "ANML". To parameterize our bioinformatics pipeline, we created an arthropod mock community consisting of single-copy (cloned) COI sequences. To examine biases associated with both PCR and HTS, mock community members were combined in equimolar amounts both pre- and post-PCR. We validated our system using guano from bats fed known diets and using composite samples of morphologically identified insects collected in pitfall traps. In PCR tests, the ANML primer pair amplified 58 of 59 arthropod taxa (98%) whereas ZBJ amplified 24-40 of 59 taxa (41-68%). Furthermore, in an HTS comparison of field-collected samples, the ANML primers detected nearly four fold more arthropod taxa than the ZBJ primers. The additional arthropods detected include medically and economically relevant insect groups such as mosquitoes. Results revealed biases at both the PCR and sequencing levels, demonstrating the pitfalls associated with using HTS read numbers as proxies for abundance. The use of an arthropod mock community allowed for improved bioinformatics pipeline parameterization. This article is protected by copyright. All rights reserved.

METHODS: The properties of tDCs in expanding Tregs and their potential to ameliorate AR were evaluated in vitro and in vivo. RESULTS: Monocyte derived tDCs stimulated with Dermatophagoides pteronyssinus allergen 1 favored the generation of activated Tregs (aTregs) and suppressed effector T-cell responses in a transforming growth factor-beta/interleukin-10 (TGF-beta/IL-10) dependent manner in vitro. The adoptive transfer of tDCs inhibited allergic airway inflammation in the mouse model, whereas depletion of CD25+ cells or blocking TGF-beta/IL-10 signaling eliminated the inhibitory effect, indicating that Tregs were involved in the anti-inflammatory activity of tDCs. CONCLUSION: Our data show that tDCs are a potential therapeutic target in AR. PMID- 30281916 TI - Alterations of EDEM1 functions enhance ATF6 pro-survival signaling. AB - Activating transcription factor 6 alpha (referred to as ATF6 hereafter) is an endoplasmic reticulum (ER)-resident glycoprotein and one of the three sensors of the unfolded protein response (UPR). Upon ER stress, ATF6 is exported to the Golgi complex where it is cleaved by the S1P and S2P proteases thus releasing ATF6 cytosolic fragment and leading to the transcription of ATF6 target genes. In this study, we performed a phenotypic small-interfering RNA (siRNA) screening to better characterize the ER mechanisms involved in ATF6 activation upon ER stress. This revealed that silencing of ER-degradation-enhancing alpha-mannosidase-like protein-1 (EDEM1) increased the bioavailability of ER stress-induced ATF6 export to the Golgi complex through the stabilization of the natively unstable ATF6 protein. Moreover, we characterized a somatic variant of EDEM1 (N198I) found in hepatocellular carcinoma that alters ATF6 signaling and might provide a selective advantage to the transforming cells. Hence, our work confirms the natively unstable nature of ATF6 and links this property to potentially associated pro oncogenic functions.

AB - INTRODUCTION: Curative radiotherapy is guideline treatment for inoperable patients of good performance status with Stage I & II Non-Small Cell Lung Cancer (NSCLC). The aim of this study was to evaluate radiotherapy patterns of care in these patients, the reasons for palliative treatment and the proportion of patients suitable for curative stereotactic ablative body radiotherapy (SABR). METHODS: Electronic oncology databases at three institutions were queried to retrieve data on patients with inoperable Stage I & II NSCLC seen in radiation oncology clinics between 1/1/2008 and 31/12/2014. Suitability for SABR was defined as peripheral tumours less than 5 cm in size. Factors associated with curative treatment were determined using univariate and multivariate analyses. RESULTS: Three-hundred-and-twelve patients were identified of whom 178 (57%) received curative radiotherapy, 58 (19%) palliative radiotherapy and 76 (24%) no radiotherapy. The main reason for receiving palliative rather than curative treatment was COPD or poor pulmonary function (26%). Method of diagnosis (P = 0.031), Simplified Comorbidity Score (P = 0.003), ECOG performance status (P = 0.016), FEV1% (P = 0.040), treating institution (P < 0.0001) and time period (P = 0.016) were associated with curative radiotherapy on multivariate analysis. In patients with T1-2N0M0 NSCLC, 19 (31%) who did not receive treatment and 7 (21%) who underwent palliative radiotherapy were technically and clinically suitable for SABR. CONCLUSION: Only 57% of patients with Stage I-II NSCLC were treated with curative radiotherapy. Patient factors were the predominant reason for palliative treatment, however, treating institution also played a role. A considerable proportion of patients who underwent palliative or no radiotherapy were suitable for SABR treatment.

AB - We aimed to explore the mechanisms of sunitinib-resistance in renal cell cancer (RCC) and provide new therapeutic evidence and biomarkers for RCC treatment using human clear-cell renal cell carcinoma (ccRCC) cell line, 786-O. Microarray analysis, quantitative real time PCR (qRT-PCR), Western blot, and immunohistochemistry were used to detect Ecto-5'-nucleotidase (NT5E) expressions in sunitinib-resistant tissues in RCC. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl 2-H-tetrazolium bromide, Thiazolyl Blue Tetrazolium Bromide (MTT), cell-count kit 8 (CCK-8), wound healing, and Transwell assays were used to investigate the influences of sunitinib and NT5E on 786-O cell line and sunitinib-resistant 786-O cell line (S786-O). Protein expressions related to epithelial-mesenchymal transition (EMT) and AKT/GSK-3beta signaling pathway in 786-O cells and S786-O cells were determined by Western blot. In vivo experiment was performed using NCr nu/nu mice to explore the effects of NT5E on cell growth and EMT signal in sunitinib environment. NT5E expression was upregulated in sunitinib-resistant RCC tissues and cells. NT5E downregulation repressed RCC cell proliferation, migration as well as invasion. EMT course and AKT/GSK-3beta signal pathway both in vitro and in vivo in sunitinib environment was suppressed to varying degrees via NT5E inhibition. NT5E inhibition could suppress the growth of sunitinib resistant RCC cells and restrain EMT course and AKT/GSK-3beta signal pathway in sunitinib environment in RCC. (c) 2018 IUBMB Life, 2018. PMID- 30281918 TI - Assessment of tumour response after stereotactic ablative radiation therapy for lung cancer: A prospective quantitative hybrid 18 F-fluorodeoxyglucose-positron emission tomography and CT perfusion study. AB - INTRODUCTION: Stereotactic ablative radiotherapy (SABR) is a guideline recommended treatment for inoperable stage I non-small cell lung cancer (NSCLC), but imaging assessment of response after SABR is difficult. The goal of this study was to evaluate imaging-based biomarkers of tumour response using dynamic 18 F-FDG-PET and CT perfusion (CTP). METHODS: Thirty-one patients with early stage NSCLC participated in this prospective correlative study. Each underwent dynamic 18 F-FDG-PET/CTP studies on a PET/CT scanner pre- and 8 weeks post-SABR. The dynamic 18 F-FDG-PET measured the tumour SUVmax , SUVmean and the following parameters: K1 , k2 , k3 , k4 and Ki , all using the Johnson-Wilson-Lee kinetic model. CTP quantitatively mapped BF, BV, MTT and PS in tumours and measured largest tumour diameter. Since free-breathing was allowed during CTP scanning, non-rigid image registration of CT images was applied to minimize misregistration before generating the CTP functional maps. Differences between pre- and post-SABR imaging-based parameters were compared. RESULTS: Tumour size changed only slightly after SABR (median 26 mm pre-SABR vs. 23 mm post-SABR; P = 0.01). However, dynamic 18 F-FDG-PET and CTP study showed substantial and significant changes in SUVmax , SUVmean , k3 , k4 and Ki . Significant decreases were evident in SUVmax (median 6.1 vs. 2.6; P < 0.001), SUVmean (median 2.5 vs. 1.5; P < 0.001), k3 (relative decrease of 52%; P = 0.002), Ki (relative decrease of 27%; P = 0.03), whereas there was an increase in k4 (+367%; P < 0.001). CONCLUSIONS: Hybrid 18 F-FDG-PET/CTP allowed the response of NSCLC to SABR to be assessed regarding metabolic and functional parameters. Future studies are needed, with correlation with long-term outcomes, to evaluate these findings as potential imaging biomarkers of response. PMID- 30281920 TI - Clinical effectiveness and safety of antazoline-based therapy in patients with stable coronary artery disease undergoing pharmacological cardioversion of short duration atrial fibrillation in the emergency department. AB - INTRODUCTION: Options for a pharmacological cardioversion (CV) of short-duration atrial fibrillation (AF) in patients with a stable coronary artery disease (CAD) are limited to amiodarone or vernakalant. Antazoline has been reported to achieve high rates of AF conversion to sinus rhythm, but data on its effectiveness and, more importantly, safety in stable CAD patients, have been sparse. AIMS: To assess the effectiveness and safety of antazoline-based therapy in patients with a stable CAD undergoing pharmacological CV of short-duration AF in the emergency department (ED). RESULTS: A retrospective case-control study. We conducted an analysis of medical records of patients with a stable CAD undergoing CV of short duration (<=48 hours) AF in the ED using intravenous antazoline. The main endpoints of the study were successful cardioversion of AF and hospitalization due to the adverse effects (AE) of the treatment. Between 2008 and 2012, out of 548 CVs, antazoline was administered 334 times: 138 in CAD and 196 in the control group. Patients in the CAD group were older and had more comorbidities than controls; 65 patients had had a history of myocardial infarction (MI). In CAD group, the effectiveness was higher (82.6% vs 63.8%, RB: 1.30 [95% CI: 1.14 1.48], P = 0.0002) and the hospitalization rate due to AE was similar (1.4% vs 4.1%, RR: 0.36 [95% CI: 0.08-1.65], P = 0.2054) to the control group. Among patients with CAD, a history of MI did not influence the effectiveness or safety of the CV (P = 0.2252 and P = 1.0000, respectively). CONCLUSIONS: In selected patients with a stable CAD, even with a history of MI, antazoline-based CV of short-duration AF may be an effective and safe therapeutic option.

AB - The structural and optical features of zirconia toughened alumina (ZTA) due to the assorted range of Eu3+ substitutions are demonstrated. The characterization studies affirm the pivotal role of Eu3+ on the improved structural stability of ZTA and associated tetragonal zirconia (t-ZrO2 ) -> cubic zirconia (c-ZrO2 ) transformation. Eu3+ prefers accommodation at the lattice sites of ZrO2 and their gradual accumulation induces t- -> c-ZrO2 transition. Beyond the substitution limit, Eu3+ reacts with Al2 O3 to form EuAlO3 . Optical studies validate typical Eu3+ emissions, and further, the emission spectrum also predicts the symmetry of Eu3+ coordination at the ZrO2 lattice. Uniform distribution of ZrO2 and Al2 O3 grains throughout the microstructures are evident from the morphological analysis. Further, the influence of Eu3+ on the enhanced mechanical stability of ZTA is ensured from indentation technique. (c) 2018 Wiley Periodicals, Inc. J Biomed Mater Res B Part B: 2018.

AB - The combretastatins have attracted significant interest as small-molecule therapies for cancer due to their ability to function as vascular disrupting agents. We have successfully prepared a range of combretastatin analogues that are based on a novel sydnone heterocycle core, and their potential as tubulin binders has been assessed in vitro and in vivo. The most potent candidate was found to disrupt microtubules and affect cellular morphology at sub-micromolar levels. Moreover, it was found to bind reversibly to tubulin and significantly increase endothelial cell monolayer permeability, in a similar manner to combretastatin A4. Surprisingly, the compound did not exhibit efficacy in vivo, possibly due to rapid metabolism. PMID- 30281923 TI - Molecular characterization of two novel atypical porcine pestivirus (APPV) strains from piglets with congenital tremor in China. AB - As one of emerging porcine viruses, atypical porcine pestivirus (APPV) was found in three continents since it emerged in 2015. It is now thought as the causative agent for congenital tremor type A-II in piglets. At the end of 2017, two APPV strains were identified from piglets with congenital tremor in Guangxi and Yunnan, China. The genome of APPV GX04/2017 strain was so far determined to be 11,534 nucleotides (nt) in length and contains a single open reading frame (ORF) encoding a polyprotein comprising 3,635 amino acids. Comparative analysis of ORF, Npro , E2, and NS3 gene sequences revealed that the APPV GX04/2017 strain shares nucleotide sequence identities of 82.8%-92.8% with other APPV strains, while YN01/2017 strain is 79.4%-97.4% homology to the others. Phylogenetic analysis showed that the APPV GX04/2017 and YN01/2017 are two novel APPV strains with the highest homology to each other, and relative high similarity to the APPV 000515 and JX-JM01 strains in genome sequence. The current findings provide updated information about APPV epidemiology and divergence in China, which would certainly help to establish reliable diagnosis and surveillance programs for APPV. PMID- 30281924 TI - Polymorphisms associated with fentanyl pharmacokinetics, pharmacodynamics and adverse effects. AB - Fentanyl is an agonist of the MU-opioid receptor commonly used in the treatment of moderate-severe pain. In order to study whether pharmacogenetics explains some of the variability in the response to fentanyl, several genes related to fentanyl receptors, transporters and metabolic enzymes have been analysed. Thirty-five healthy volunteers (19 men and 16 women) receiving a single 300 MUg oral dose of fentanyl were genotyped for 9 polymorphisms in cytochrome P450 (CYP) enzymes (CYP3A4 and CYP3A5), ATP-binding cassette subfamily B member 1 (ABCB1), opioid receptor mu 1 (OPRM1), catechol-O-methyltransferase (COMT) and adrenoceptor beta 2 (ADRB2) by real-time PCR. Fentanyl concentrations were measured by ultra performance liquid chromatography combined with tandem mass spectrometry (UPLC MS/MS). Fentanyl pharmacokinetics is affected by sex. Carriers of the CYP3A4*22 allele, which is known to reduce the mRNA expression, showed higher area under the concentration-time curve (AUC) and lower clearance (Cl) values. Although this finding might be of importance, its validity needs to be confirmed in other similar settings. Furthermore, carriers of the ABCB1 C1236T T/T genotype presented a lower AUC and higher Cl, as well as lower half-life (T1/2 ). As volunteers were blocked with naltrexone, the effect of fentanyl on pharmacodynamics might be biased; however, we could observe that fentanyl had a hypotensive effect. Moreover, ADRB2 C523A A allele carriers showed a tendency towards reducing systolic blood pressure. Likewise, OPRM1 and COMT minor allele variants were risk factors for the development of somnolence. CYP3A5*3, ABCB1 C3435T and ABCB1 G2677T/A were not associated with fentanyl's pharmacokinetics, pharmacodynamics and safety profile.

AB - BACKGROUND: T-helper 2 (Th2) polarization plays a critical role in the pathogenesis of chronic rhinosinusitis (CRS) with accompanying nasal allergy. Recent studies indicate that B cell lymphoma-2-like protein-12 (Bcl2L12) is associated with immune dysregulation. The purpose of this study was to elucidate the role of Bcl2L12 in the pathogenesis of Th2 polarization of CRS patients. METHODS: CRS patients with nasal allergy (CRSa) and without nasal allergy (CRSna) were recruited into this study. CD4+ T cells were isolated from the blood samples of human subjects. A variety of immunologic molecular strategies were used to assess Th2 polarization and Bcl2L12 expression. RESULTS: Twenty CRSa patients, 20 CRSna patients, and 20 healthy subjects were recruited into this study. High levels of immunoglobulin E (IgE), interleukin 4 (IL-4), IL-5, IL-13, and Bcl2L12 were detected in nasal extracts of CRSa patients, but not in CRSna patients. The levels of Bcl2L12 were positively correlated with Th2 cytokines. CD4+ T cells from CRSa patients were prone to differentiate into Th2 cells, in which Bcl2L12 was required. CONCLUSION: Bcl2L12 is positively correlated with Th2 cytokine levels in the nasal mucosa of CRSa patients. Bcl2L12 contributes to the Th2 polarization, which may be a novel therapeutic target in the treatment of CRSa. PMID- 30281928 TI - SNOT-22 score patterns strongly negatively predict chronic rhinosinusitis in patients with headache. AB - BACKGROUND: Differentiating the non-sinogenic headache from chronic rhinosinusitis (CRS) remains a significant clinical challenge due to the extensive overlap in symptoms. The objective of this study was to evaluate the 22 item Sino-Nasal Outcome Test (SNOT-22) score patterns in patients with confirmed non-sinogenic headache in order to develop negative predictors of CRS. METHODS: Institutional Review Board (IRB)-approved, retrospective review of patients diagnosed with CRS or non-sinogenic headache defined as patients with a chief complaint of headache, facial pain, and facial pressure in the absence of both endoscopic and computed tomography (CT) evidence of inflammation. The optimal cutoff points of potential predictors of non-sinogenic headache by SNOT-22 score were quantified by receiver operating characteristic (ROC) curve. The negative predictive values (NPVs) for CRS were calculated in a discovery population and then validated in an independent population. RESULTS: A total of 724 (164 non sinogenic headache and 560 CRS) and 412 (88 non-sinogenic headache and 324 CRS) patients were recruited in the discovery and validation populations, respectively. Domain 3 (Ear/facial) and domain 4 (Psychological dysfunction) were significantly higher in patients with non-sinogenic headache as compared with CRS while domain 1 (Rhinologic) and domain 2 (Extranasal rhinologic) were significantly lower. The top 4 predictors of non-sinogenic headache were the domain 3 (Ear/facial)/domain 1 (Rhinologic) ratio, item 12, domain 3 (Ear/facial), and (item 12 + item 10)/(item 4 + item 5) ratio, with areas under the ROC curve (AUCs) ranging from 0.637 to 0.720 by ROC curve. A domain 3 (Ear/facial)/domain 1 (Rhinologic) ratio over 0.66 performed as the best negative predictor of CRS with the highest NPVs of 0.880 and 0.889 in the discovery and validation populations, respectively. CONCLUSION: Patients with non-sinogenic headache have distinct SNOT-22 score patterns compared with patients with CRS. A domain 3 (Ear/facial)/domain 1 (Rhinologic) ratio greater than 0.66 is a strong negative predictor of CRS, which can be used to aid in patient counseling and potentially limit the use of unnecessary sinonasal therapeutics. PMID- 30281929 TI - 14-3-3 protein masks the nuclear localization sequence of caspase-2. AB - Caspase-2 is an apical protease responsible for the proteolysis of cellular substrates directly involved in mediating apoptotic signaling cascades. Caspase-2 activation is inhibited by phosphorylation followed by binding to the scaffolding protein 14-3-3, which recognizes two phosphoserines located in the linker between the caspase recruitment domain and the p19 domains of the caspase-2 zymogen. However, the structural details of this interaction and the exact role of 14-3-3 in the regulation of caspase-2 activation remain unclear. Moreover, the caspase-2 region with both 14-3-3-binding motifs also contains the nuclear localization sequence (NLS), thus suggesting that 14-3-3 binding may regulate the subcellular localization of caspase-2. Here, we report a structural analysis of the 14-3 3zeta:caspase-2 complex using a combined approach based on small angle X-ray scattering, NMR, chemical cross-linking, and fluorescence spectroscopy. The structural model proposed in this study suggests that phosphorylated caspase-2 and 14-3-3zeta form a compact and rigid complex in which the p19 and the p12 domains of caspase-2 are positioned within the central channel of the 14-3-3 dimer and stabilized through interactions with the C-terminal helices of both 14 3-3zeta protomers. In this conformation, the surface of the p12 domain, which is involved in caspase-2 activation by dimerization, is sterically occluded by the 14-3-3 dimer, thereby likely preventing caspase-2 activation. In addition, 14-3-3 protein binding to caspase-2 masks its NLS. Therefore, our results suggest that 14-3-3 protein binding to caspase-2 may play a key role in regulating caspase-2 activation.

PMID- 30281930 TI - Impact of chronic rhinosinusitis on sleep: a controlled clinical study. AB - BACKGROUND: Earlier studies have suggested that patients with chronic rhinosinusitis (CRS) report worse sleep quality than population norms. What remains unknown is whether these patients are actually experiencing measurable changes in objective sleep parameters. The goal of this study was to prospectively evaluate objective sleep measures in a cohort of patients with CRS. METHODS: A prospective, multi-institutional, case-control study was designed to compare patients with CRS to nondiseased controls. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (EpSS). Home sleep studies were administered across all subjects and a battery of objective sleep measurements were recorded using a portable sleep diagnostic device. Regression models were used to control for any factors that differed across groups. RESULTS: A total of 108 subjects were enrolled across 4 institutions, including 52 patients with CRS and 56 controls. Total PSQI scores were worse in patients with CRS when compared with controls (10.1 +/- 4.3 vs 4.7 +/- 2.5; p < 0.001). Similarly, daytime somnolence, as measured by the EpSS, was greater in patients with CRS (9.1 +/- 5.3 vs 6.5 +/- 3.7; p = 0.006). On home sleep studies, patients with CRS were found to have an increased number of awakenings during a night's sleep (8.6 +/- 4.8 vs 6.3 +/- 3.0; p = 0.004), lower average overnight oxygen saturation (93.2 +/- 2.6% vs 94.3 +/- 2.1%; p = 0.042), increased rapid eye movement sleep (REMS) latency (93.0 +/- 67.1 vs 66.7 +/- 35.3; p = 0.016), and spent a greater portion of the night snoring at >40 dB (24.7 +/- 27.4% vs 14.6 +/- 19.7%; p = 0.034). All differences except mean oxygen saturation remained significant after controlling for baseline differences. CONCLUSION: Differences in both patient-reported and objective sleep measures exist between patients with CRS and controls.

AB - This study evaluates the use of HMG-CoA reductase inhibitors, or statins, as an adjunctive to BRAF and MEK inhibition as a treatment in melanomas and other tumors with driver mutations in the MAPK pathway. Experiments used simvastatin in conjunction with vemurafenib and selumetinib in vitro and simvastatin with vemurafenib in vivo to demonstrate additional growth abrogation beyond MAPK blockade alone. Additional studies demonstrated that statin anti-tumor effects appeared to depend on inhibition of isoprenoid synthesis given rescue with add back of downstream metabolites. Ultimately, we concluded that statins represent a possible useful adjunctive therapy in MAPK-driven tumors when given with current approved targeted therapy. PMID- 30281932 TI - Genetic Engineering of Human Pluripotent Stem Cells Using PiggyBac Transposon System. AB - Human pluripotent stem cells (hPSCs) emerged as an important tool to investigate human development and disease. These studies often require genetically engineering hPSCs to stably express a transgene, which remains functional in various hPSC progeny. PiggyBac transposon is a highly effective and technically simple vector system with large cargo space available for permanent gene delivery. This unit describes the use of PiggyBac transposons to genetically engineer hPSCs to introduce conditionally expressed transgene or reporter to effectively monitor gene expression during differentiation. Both methods enable robust generation of stable hPSC lines within 1 month. (c) 2018 by John Wiley & Sons, Inc. PMID- 30281933 TI - Deletion of Nrf2 enhances susceptibility to eosinophilic sinonasal inflammation in a murine model of rhinosinusitis. AB - BACKGROUND: Oxidative stress exacerbates lower airway diseases including asthma and chronic obstructive pulmonary disease (COPD); however, its role in upper airway (sinonasal) chronic inflammatory disorders is less clear. Nuclear erythroid 2 p45-related factor (Nrf2) is an endogenous mechanism that upon activation invokes an antioxidant response pathway via nuclear translocation and upregulation of cytoprotective genes. We sought to determine whether deletion of Nrf2 enhances susceptibility to allergic sinonasal inflammation in vivo. METHODS: Nrf2-/- mice were subjected to the ovalbumin (Ova)-induced murine model of rhinosinusitis and indices of sinonasal inflammation and epithelial barrier dysfunction were assessed. RESULTS: We show that deletion of Nrf2 results in enhances indices of allergen-induced sinonasal inflammation including aggravated eosinophil accumulation and goblet cell hyperplasia. An exaggerated increase in epithelial derived inflammatory cytokines including interleukin 33 (IL-33) and thymic stromal lymphopoietin (TSLP) was observed in the nasal lavage fluid and sinonasal mucosal tissue of Nrf2-/- mice. Furthermore, Nrf2-/- mice showed heightened Ova-induced barrier dysfunction as measured by serum albumin accumulation in nasal lavage fluid of mice. CONCLUSION: These data show that the endogenous Nrf2 pathway limits Ova-induced sinonasal inflammation, epithelial derived inflammatory cytokine production, and epithelial barrier dysfunction in vivo and identify a potential therapeutic target in the management of allergic sinonasal inflammatory disorders. This is the first study to our knowledge which shows that Nrf2 regulates allergic inflammation in the sinonasal cavity in vivo.

Advancing our understanding of disease pathogenesis translates into better patient care. Because of their unique position, laboratorians are the best to accurately identify, annotate, and classify research specimens. They also are essential for the accurate interpretation of genomic testing. Currently, cytopathologists are moving to the center of patient care through active communication with clinicians and patients. There are certain research areas in which cytopathologists can be pioneers, such as image analysis, morphology research, and genotype-phenotype association studies integrating morphologic and molecular features. Health service utilization research is another domain in which cytopathologists can excel. Successful research is a journey that necessitates multiple steps. It also involves building expertise in how to overcome obstacles and handle challenges. PMID- 30281934 TI - Compromising Between Phase Stability and Electrical Performance: SrVO3 -SrTiO3 Solid Solutions as Solid Oxide Fuel Cell Anode Components. AB - The applicability of perovskite-type SrVO3-delta in high-temperature electrochemical energy conversion technology is hampered by the limited stability domain of the perovskite phase. The aim of the present work was to find a compromise between the phase stability and electrical performance by designing solid solutions in the SrVO3 -SrTiO3 system. Increasing titanium content in SrV1 y Tiy O3-delta (y=0-0.9) perovskites is demonstrated to result in a gradual shift of the upper-p(O2 ) phase stability boundary toward oxidizing conditions: from ~10-15 bar at 900 degrees C for undoped SrVO3-delta to ~10-11 -10-5 bar for y=0.3-0.5. Although the improvement in the phase stability is accompanied by a decrease in electrical conductivity, the conductivities of SrV0.7 Ti0.3 O3-delta and SrV0.5 Ti0.5 O3-delta at 900 degrees C remain as high as 80 and 20 S cm-1 , respectively, and is essentially independent of p(O2 ) within the phase-stability domain. Combined XRD, thermogravimetric analysis, and electrical studies revealed very sluggish kinetics of oxidation of SrV0.5 Ti0.5 O3-delta ceramics under inert gas conditions and a nearly reversible behavior after exposure to an inert atmosphere at elevated temperatures. Substitution by titanium in the SrV1-y Tiy O3-delta system results also in a decrease of oxygen deficiency in perovskite lattice and a favorable suppression of thermochemical expansion. Variations of oxygen nonstoichiometry and electrical properties in the SrV1-y Tiy O3-delta series are discussed in combination with the simulated defect chemistry of solid solutions. PMID- 30281936 TI - Analysis of Cysteine Post Translational Modifications Using Organic Mercury Resin. AB - The wide reactivity of the thiol group enables the formation of a variety of reversible, covalent modifications on cysteine residues. S-nitrosylation, like many other post-translational modifications, is site selective, reversible, and necessary for a wide variety of fundamental cellular processes. The overall abundance of S-nitrosylated proteins and reactivity of the nitrosyl group necessitates an enrichment strategy for accurate detection with adequate depth. Herein, a method is presented for the enrichment and detection of endogenous protein S-nitrosylation from complex mixtures of cell or tissue lysate utilizing organomercury resin. Minimal adaptations to the method also support the detection of either S-glutathionylation or S-acylation using the same enrichment platform. When coupled with high accuracy mass spectrometry, these methods enable a site specific level of analysis, facilitating the curation comparable datasets of three separate cysteine post-translational modifications.

AB - Directly bonded piezo sensor, conventionally employed in the electromechanical impedance (EMI) technique, although a proven candidate for structural health monitoring, is severely constrained in its application in the biomedical field due to its bonding requirement. In contrast, nonbonded piezo sensor (NBPS) provides a viable platform to assess the condition of human bones, tissues, and other biomedical subjects using the EMI technique without inflicting pain or irritation to the skin. The name NBPS was coined to emphasize that there was no direct bonding between the PZT patch and the live subject; instead, the PZT patch was bonded to a supporting medium, which maintains the mechanical interaction between the PZT patch and the subject. However, there are several aspects in the analysis of NBPS configuration that cannot be addressed completely through experimental study due to measurement constraints, cost, and time. For example, experimentally changing the density of bone continuously to study the osteoporosis effect is a tedious task warranting large number of specimens. This paper presents a detailed parametric study based on finite element method covering condition monitoring of human bones using the NBPS configuration. It is for the first time that 3D analysis for specimen identification and damage detection in bones using NBPS has been carried out. In addition to the validation of the numerical model against the previously established experimental studies involving bones, quantification of the extent of damage and its localization has been investigated. The density changes due to osteoporosis in bones are comprehensively investigated by the NBPS including the quantification aspect of osteoporosis/damage. Definite acquisition of bone signature and detection of physiological changes in bones are achieved even with the presence of skin, muscle, and fat layers on the bone. PMID- 30281938 TI - Management and outcome of epistaxis under direct oral anticoagulants: a comparison with warfarin. AB - BACKGROUND: Epistaxis is one of the more common reasons for emergency room visits. The main risk factor for epistaxis is anticoagulant therapy. Until recently, the main culprit was oral intake of a vitamin K antagonist, such as warfarin, which has a number of side effects. Even more recently, several direct oral anticoagulants, rivaroxaban and dabigatran, have been approved for use. We investigated the possible differences between treatment of epistaxis with direct oral anticoagulants and vitamin K antagonists. METHODS: We conducted a retrospective cohort study at a tertiary referral center in Germany. All patients who were admitted within a 1-year period were included. Patient files were used to obtain the information. RESULTS: Overall, 677 patients were included in our study. Of these, 159 had been treated with vitamin K antagonists and 49 with direct oral anticoagulants. There were no significant differences in terms of age (p = 0.592), sex (p = 0.372), vital signs, bloodwork, or location of bleeding (p = 0.372). Management of epistaxis between the groups was also comparable (p = 0.399), with similar hospital admission rates (37.1% vs 24.5%; p = 0.145) and duration of stay (3.5 +/- 2.1 days vs 3.8 +/- 3.3 days; p = 0.650). CONCLUSION: We found no evidence to suggest epistaxis is more severe or requires more invasive therapy in patients given direct oral anticoagulants. A significant proportion of patients on vitamin K antagonists were not within the target range for international normalized ratio, highlighting one of the main issues with oral anticoagulation by vitamin K antagonists.

AB - BACKGROUND: M2 macrophages are characterized by high interleukin-10 (IL-10) expression and are critical for resolving inflammation. Although increased accumulation of M2 macrophages has been demonstrated in chronic rhinosinusitis with nasal polyps (CRSwNP), particularly the eosinophilic type, their functional relevance in CRSwNP remains poorly understood. METHODS: M1 and M2 macrophages and IL-10 expression in sinonasal tissues were detected by double-immunofluorescence staining. THP-1 cells, a human monocytic leukemia cell line, were stimulated with various cytokines to study macrophage polarization and IL-10 expression. Polyp size, computed tomography (CT) scans, and symptom severity were scored. RESULTS: Compared with numbers in control tissues, the numbers of total CD68+ macrophages, interferon regulatory factor 5-positive and CD68+ M1 macrophages, and CD163+ CD68+ and CD206+ CD68+ M2 macrophages were increased in both eosinophilic and non eosinophilic polyps. However, compared with non-eosinophilic polyps, eosinophilic polyps contained fewer M1 macrophages and more M2 macrophages. Consistent with this, the M1/M2 macrophage ratio was increased in non-eosinophilic polyps, whereas it decreased in eosinophilic polyps. Strikingly, the numbers of IL-10+ CD68+ macrophages and the percentage of IL-10+ CD68+ macrophages relative to the total number of macrophages were decreased in eosinophilic polyps, despite the upregulation of M2 macrophages in this type of polyp. The number of IL-10+ CD68+ M2 macrophages correlated negatively with total symptoms scores, polyp sizes, total CT scores, and the total number of inflammatory cells in patients with eosinophilic CRSwNP. Poly I:C downregulated IL-10 expression in M2 macrophages differentiated from THP-1 cells in vitro. CONCLUSION: Impaired IL-10 production by M2 macrophages may contribute to sustained inflammation in eosinophilic CRSwNP.vv.

AB - Mucohaemorrhagic diarrhea associated with Brachyspira hampsonii infection has emerged as a production-limiting disease in western Canada. This pathogen was first described in North America in 2010, and reports of its detection occurred concurrently in western Canada and the United States. Since that time, Brachyspira hampsonii has been detected in Europe, both in pigs and in waterfowl. The origin of B. hampsonii and the timing and reasons for its emergence are unknown. We conducted a retrospective study of historic, archived cases of porcine colitis to determine when B. hampsonii was first evident in western Canada. A total of 206 samples from 114 cases submitted from 57 different farms or productions systems in 1984 and 1999-2009 were screened using real-time PCR assays targeting B. hampsonii genomovars I and II, and Brachyspira hyodysenteriae (the traditional agent of swine dysentery). In most cases, positive real-time PCR results were confirmed by amplification and sequencing of additional gene targets. A total of 9, 7 and 5 samples tested positive for B. hampsonii (I), B. hampsonii (II) or B. hyodysenteriae respectively. The results of this study push the date of first appearance of B. hampsonii in pigs in western Canada back to 2002 (B. hampsonii (I)) and 2006 (B. hampsonii (II)), which is up to 7 years before the new species were first identified in fresh samples. PMID- 30281941 TI - Effects of mometasone furoate-impregnated biodegradable nasal dressing on endoscopic appearance in healing process following endoscopic sinus surgery: a randomized, double-blind, placebo-controlled study. AB - BACKGROUND: Postoperative care is an important factor affecting the outcome of endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis (CRS). The aim of this study was to test the effect of mometasone furoate (MF)-soaked biodegradable nasal dressings (BNDs) on endoscopic appearance in CRS patients with nasal polyps (CRSwNP) after ESS. METHODS: This study was a prospective, randomized, double-blinded, placebo-controlled study. A total of 64 CRSwNP patients with bilateral ESS were enrolled and randomly given 4 mL or 8 mL of MF soaked BNDs (NasoPore) in 1 nasal cavity and the same amount of normal saline soaked BNDs in the contralateral side. The BNDs were removed on the 7th or 14th postoperative day. Perioperative sinus endoscopy (POSE) and Lund-Kennedy scores were collected, on the 7th or 14th postoperative days and at 1, 2, and 3 postoperative months. RESULTS: The POSE and Lund-Kennedy scores showed that in the 4-mL, 1-week group, no significant differences between the sides treated with MF-soaked BNDs and the normal saline-soaked control were observed at any postoperative visits. In the 4-mL, 2-week group, significant differences were found at the 2-week and 1-month postoperative visits but not at the 2-month and 3 month visits. In the 8-mL, 1-week group, significant differences were found at the 1-week, 1-month, and 2-month postoperative visits but not at the 3-month visit. In the 8-mL, 2-week group, significant differences were found at all postoperative visits. CONCLUSION: This study reveals that MF-impregnated BNDs improve the endoscopic appearance in the healing process of CRSwNP after ESS.

AB - Bluetongue (BT) is a ruminant viral infectious disease transmitted by Culicoides spp. midges. In 2006, when bluetongue virus serotype 8 (BTV-8) appeared for the first time in Northern Europe, it rapidly spread and infected a large proportion of animals. BThas a significant economic impact due to a direct effect on animal health and to an indirect effect in disrupting international trade of animals and animal products. In spring 2008, a compulsory subsidized vaccination programme in Europe resulted in a drastic decrease in the number of reported cases. However, due to the turn-over of the population, without a continuous vaccination programme, the animal population was becoming progressively susceptible. Vaccination would enable Belgium to maintain its status of freedom from infection of BTV-8 that could possibly be re-introduced. Subsidizing it could be an incentive to convince more farmers to vaccinate. To finance this programme, both decision-makers and stakeholders need to be persuaded by the effectiveness and the cost-benefit of vaccination. The study evaluated the effectiveness of vaccination against BTV-8 in Belgium. The change in serology which has shown the effectiveness of the vaccine to induce antibody production has been significantly associated with the time between the first injection and the sampling date and the number of injections of the primo-vaccination. This study also clearly confirms the benefit of vaccination by reducing economic impact of treatment and production losses, especially in dairy cattle. Based on a participating epidemiological approach, a national voluntary and subsidized vaccination was accepted, and permitted Belgium to vaccinate more than 9,000 herds in 1 month. Because this mass vaccination occurred before the vector season, it probably helped Belgium remain free from BTV-8. PMID- 30281943 TI - Establishment of a CFD-based kL a model in microtiter plates to support CHO cell culture scale-up during clone selection. AB - Microtiter plates are a common tool for clone selection in biopharmaceutical development. A way of visualizing and evaluating these systems and key processes parameters is the application of Computational Fluid Dynamics (CFD). CFD is a powerful tool for the modelling of hydrodynamics and mass transfer parameters. In this work, CFD was used to determine the specific surface area, the volumetric power input and the oxygen mass transfer coefficient kL a for two different microtiter plates with different scales (100 MUL - 5 mL). For this purpose, a new method of predicting the kL a is presented and calibrated with literature data. Scaling effects in shaken microtiter plates are evaluated by comparing two culture volume scales under various operating conditions. To test validity of these models, three different Boehringer Ingelheim Pharma proprietary CHO production cell lines with different growth characteristics were cultivated using the respective microtiter plates under different conditions until limitations in growth and viability were observable. The cell culture data then was compared to different parameters obtained by CFD. The calculated kL a values match the cell culture performance in the 96-deepwell by predicting lowered oxygen transfer with increasing culture volume and decreasing orbital velocity. The same cells behave differently in the 6-deepwell scale. Here, the overall larger shear stress might cause physical stress for the cells. The kL a model predicts overall higher shear rates for this system, supporting the experimental findings. (c) 2018 American Institute of Chemical Engineers Biotechnol. Prog., 2018. PMID- 30281944 TI - Genetic diversity of Leishmania tropica in Morocco: does the dominance of one haplotype signify its fitness in both predominantly anthropophilic Phlebotomus sergenti and human beings? AB - In Morocco, cutaneous leishmaniasis (CL) caused by Leishmania tropica is endemic to locations where the predominantly anthropophilic blood-feeding Phlebotomus sergenti and humans co-perpetuate. The objective of this study was to explore whether the range of epidemiological features of CLcould be linked to the range of L. tropica genetic heterogeneity and to further explore the relationships between the genetic diversity of L. tropica in both P. sergenti and humans. L. tropica DNAwas extracted from dermal scarping smears of 125 CLpatients. Genetic polymorphisms were analyzed by sequencing the internal transcribed spacer (ITS) 1 and 5.8S rDNAgene. Nucleotide diversity (pi), haplotype diversity (Hd) and Tajima's D test for neutrality, as well as overall and pairwise FSTvalues, were calculated using Arlequin ver 3.5 software. Out of the 125 amplified DNAsequences, 93 were completely sequenced and 13 L. tropica haplotypes were identified, which confirmed the significant genetic heterogeneity of L. tropica in Morocco. The most common haplotype included 74 out of 93 sequences; this haplotype is not only widely represented but was also detected in P. sergenti, which is known to be the most abundant species in the studied foci. Considering the negative value calculated using Tajima's D index, we briefly discussed the hypothesis that the L. tropica common haplotype propagation could be a sign of its fitness in P. sergenti and human hosts. Furthermore, analysis of molecular variance (AMOVA) shows significant correlations between intraspecific variants of L. tropica and patients' geographic origins. The long-term goals of the present pilot study are to further explore the relationships between the genetic diversity of L. tropica in human and P. sergenti populations. PMID- 30281945 TI - Allergic rhinitis and the associated risk of nocturnal enuresis in children: a population-based cohort study. AB - BACKGROUND: Despite controversy, an association between allergy and nocturnal enuresis (NE) has been reported for almost a century. Allergic rhinitis (AR) associated sleep-disordered breathing frequently results in microarousals during sleep, decreased sleep efficiency, and change in sleep pattern and behavior. NE is a common sleep disorder in children. Hence, this study aimed to investigate the incidence and risk of NE in children with AR. METHODS: A population-based cohort study was conducted among 327,928 children with AR and 327,601 non-AR controls between 2000 and 2012 in Taiwan. By the end of 2012, the incidence of NE in both cohorts, and the AR-to-non-AR cohort hazard ratios (HRs) were measured. RESULTS: The adjusted HR of NE during the study period was 1.7-fold higher in the AR cohort compared to the non-AR cohort. The risk was greater for boys, children younger than 6 years old, those with comorbidities of asthma, atopic dermatitis, and attention deficit/hyperactivity disorder (ADHD), and those who had more than 5 AR-related medical visits per year. The risk of NE in the AR cohort decreased with follow-up time and was the highest within the first year after AR diagnosis. CONCLUSION: Children with AR had a higher incidence and subsequent risk of NE. The risk of NE was greater for boys, younger children, and those with more frequent health utilization for AR symptoms. PMID- 30281946 TI - Resting cells isobutanol production by Shimwellia blattae (p424IbPSO): Influence of growth culture conditions. AB - Isobutanol is a promising gasoline additive and could even be a potential substitute used directly as combustible. In this work, the production of isobutanol from glucose by Shimwellia blattae (p424IbPSO) in resting cell cultures is studied. This production has two stages, involving a resting cell phase that has not been studied before. The cell growth was carried out under different operating conditions: temperature and medium composition (YE, ammonium, and IPTG concentrations), looking for the highest isobutanol production. Moreover, the cells were collected at three different growth times checking their isobutanol production capacity. The best operating conditions have been determined as: 30 degrees C of temperature, a medium containing 1.5 g L-1 YE and 1.4 g L-1 of ammonium as nitrogen sources, adding 0.5 mM IPTG as inducer. The cells collected at early growth times are significantly more active. The use of S. blattae (p424IbPSO) in resting cells is a good strategy for the production of isobutanol from glucose yielding better results than in batch growth cultures, a yield of 60% attainment of theoretical maximum yield is obtained under optimal conditions. In addition, it has been demonstrated that if the cells are cultured at higher temperatures and with high IPTG concentrations, inclusion bodies are formed in the cytoplasm inhibiting the isobutanol production in the resting cell stage. PMID- 30281947 TI - Glucose Monitoring and Adaptive Feeding of Mammalian Cell Culture in the Presence of Strong Autofluorescence by near Infrared Raman Spectroscopy. AB - Raman spectroscopy offers an attractive platform for real-time monitoring and control of metabolites and feeds in cell culture processes, including mammalian cell culture for biopharmaceutical production. However, specific cell culture processes may generate substantial concentrations of chemical species and byproducts with high levels of autofluorescence when excited with the standard 785 nm wavelength. Shifting excitation further toward the near-infrared allows reduction or elimination of process autofluorescence. We demonstrate such a reduction in a highly autofluorescent mammalian cell culture process. Using the Kaiser RXN2-1000 platform, which utilizes excitation at 993 nm, we developed multivariate glucose models in a cell culture process which was previously impossible using 785 nm excitation. Additionally, the glucose level in the production bioreactor was controlled entirely by Raman adaptive feeding, allowing for maintenance of glucose levels at an arbitrary set point for the duration of the culture.

AB - Both alpha-ketoglutaric acid (KGA) and pyruvic acid (PYR) are important keto acids. Efficient co-production of KGA and PYR has been achieved in our previous work, and could significantly decrease the cost of fermentation production. KGA and PYR have similar physical and chemical properties. Hence, finding a way to separate the two keto acids efficiently has become a key challenge. In this study, different chromatographic methods have been investigated, including ion exchange chromatography, aluminum oxide chromatography and silica gel chromatography. The results show that the two keto acids can be well separated with silica gel chromatography, whereas ion-exchange chromatography and aluminum oxide chromatography could not separate them. Using the pretreated fermentation broth of Yarrowia lipolytica WSH-Z06, the purity and yield of KGA/PYR reached 98.7%/99.1% and 86.7%/70.9%, respectively, with an optimized silica gel chromatography-based procedure. This study provides an efficient method for separating KGA and PYR from fermentation broth, which might be applied on an industrial scale and significantly decrease the cost of biotechnological production of keto acids.

PMID- 30281949 TI - High genetic diversity in the Dirofilaria repens species complex revealed by mitochondrial genomes of feline microfilaria samples from Narathiwat, Thailand. AB - Dirofilaria repens is a zoonotic, mosquito-borne filaria infecting carnivores, particularly dogs. It is expanding its range in Europe but epidemiological information is sparse for other Eurasian regions. In Hong Kong and India, the closely related species Candidatus Dirofilaria hongkongensis was proposed. Previous analysis of 2.5 kb partial mitochondrial genome sequences containing the particularly variable non-coding control region revealed low diversity in European D. repens while Asian nematodes showed high diversity. Sequences derived from feline blood samples from Narathiwat (Thailand) led to the proposal of a third potential species, Dirofilaria sp. "Thailand II". To avoid bias from rapidly evolving non-coding regions, this study aimed to compare Dirofilaria sp. "Thailand II" with D. repens and C. D. hongkongensis based on complete mitochondrial genomes. Using PCRs and Sanger sequencing, three complete mitochondrial genomes (13,651 bp) were assembled from DNA obtained from different feline blood samples. Mitochondrial genome organization was identical to other onchocercids with eleven protein-coding, two rRNA and 22 tRNA genes and no atp-8 gene. All genes were on the same strand showing an extremely high thymidine content (56.7%). Maximum-likelihood phylogenetic analysis using protein and rRNA sequences confirmed closer relationship of Dirofilaria sp. "Thailand II" to C. D. hongkongensis than to D. repens. All distances between these three putative species were considerably larger than the distance between the valid sibling species Onchocerca volvulus and Onchocerca ochengi. Sequencing of a 2.5 kb fragment containing the control region from microfilarial DNA from additional feline blood samples from Narathiwat 3-4 years later revealed that these also fell into the C. D. hongkongensis clade but were remarkably different from C. D. hongkongensis and Dirofilaria sp. "Thailand II". Since D. repens-like filaria are absent from dogs in Narathiwat, further field studies are required to confirm if these genotypes represent locally circulating cat-specific Dirofilaria genotypes or species. PMID- 30281950 TI - Propagation and Purification of Ectromelia Virus. AB - Ectromelia virus (ECTV) is an orthopoxvirus that causes mousepox in mice. Members of the genus orthopoxvirus are closely related and include variola (the causative agent of smallpox in humans), monkeypox, and vaccinia. Common features of variola virus and ECTV further include a restricted host range and similar disease progression in their respective hosts. Mousepox makes an excellent small animal model for smallpox to investigate pathogenesis, vaccine and antiviral agent testing, host-virus interactions, and immune and inflammatory responses. The availability of a wide variety of inbred, congenic, and gene-knockout mice allows detailed analyses of the host response. ECTV mutant viruses lacking one or more genes encoding immunomodulatory proteins are being used in numerous studies in conjunction with wild-type or gene-knockout mice to study the functions of these genes in host-virus interactions. The methods used for propagation of ECTV in cell culture, purification, and quantification of infectious particles through viral plaque assay are described. (c) 2018 by John Wiley & Sons, Inc.

AB - C-phycocyanin (C-PC) is a natural blue dye, and depending on its purity, which is measured by the ratio between the absorbance of the chromophore (A620 ) and the absorbance of the proteins (A280 ), it can be used in food (purity > 0.7), cosmetics (purity > 1.5), and therapeutic treatments (purity > 4.0). Several physical, chemical, and enzymatic methods of extraction are reported, however, few are able to extract C-PC with purity above 0.7. An innovative method of C-PC extraction with food grade purity from wet Spirulina platensis biomass is proposed. The cells were pretreated with ethylenediaminetetraacetic acid and subsequent C-PC extraction was performed with tris-(hydroxymethyl) aminomethane SO4 buffer. C-PC was released after 12 h of cell pretreatment. Six variables of the extraction process were evaluated. The extraction temperature significantly influenced C-PC extraction yield and purity. In the best condition of cell pretreatment and extraction, C-PC with purity of 1.0 and extraction yield of 129.0 mg/g could be obtained to be used as a food dye without any purification process. Lastly, an ultrafiltration process was integrated and C-PC was concentrated 8.8-fold, resulting in purity of 1.6 and recovery of 93.4%.

AB - Volatile fatty acids (VFAs) produced via anaerobic digestion (AD) are regarded as a low cost production process of building blocks of interest for the chemical industry. In this study, VFAs and methane production were assessed in batch reactors at different temperature ranges (psychrophilic 25 degrees C, mesophilic 35 degrees C, thermophilic 50 degrees C) and different pH values (5.5 and 7.5) using protease pretreated Chlorella sp. biomass as substrate. Acetic acid and propionic acid were the most abundant products (up to 73% of the total VFAs) during the first days independently of the conditions. VFAs concentration decreased over time as methane was produced after a lag phase of 7-10 days. Results showed that best conditions for VFAs production were mesophilic temperature ranges (35 degrees C) at neutral initial pH values (7.5), and psychrophilic temperature ranges (25 degrees C) at low initial pH values (5.5) which resulted in a conversion of the initial COD into VFAs of 48%, respectively.

AB - The adsorption of commercial trypsin (Try) onto epichlorohydrin cross-linked alginate-guar gum matrix has been studied at equilibrium in batch and in fixed bed column. Experiments were conducted to study the effect of ionic strength, temperature and to obtain a thermodynamic characterization of the adsorption process. The resulting adsorption isotherm fitted the Hill equation. Experimental breakthrough curve profiles were compared with the theoretical breakthrough profiles obtained from the mathematical model, bed depth service time. At pH 5.0, 1.0 g hydrated matrix adsorbed 480.0 milligram of Try per gram of dried bed. The desorption process showed 80% of Try recovery in 50 mM phosphate buffer, pH 7.00 500 mM NaCl-20% propylene glycol. The obtained results were applied to an adsorption/washing/desorption process with fresh pancreas homogenate yielded 20% of recovery and 5.7 purification factor of Try. The matrix remained functional until the fifth cycle of repeated batch enzyme adsorption. (c) 2018 American Institute of Chemical Engineers Biotechnol. Prog., 2018.

AB - In recent years, health authorities have increased emphasis on demonstrating that a cell line, which is used for the generation of biologics, is clonally derived. Within the past few years, single-cell manipulation technologies, especially microfluidic drop-on-demand dispensing, have gained increased attention in the biopharmaceutical industry. This work discusses the development and characterization of a single-cell printing workflow followed by plate imaging. By combining single-cell printing and plate imaging with manual image verification it is possible to, (1) dramatically reduce the number of microtiter plates needed during the single-cell cloning of clinical cell lines, as compared with a limiting-dilution single-cell cloning workflow, and therefore reduce the number of high-resolution images acquired and stored and (2) achieve >99.99% assurance that the cell lines derived from this workflow are clonally derived.

AB - Fatty acids are valuable products because they have wide industrial applications in the manufacture of detergents, cosmetics, food, and various biomedical applications. In enzyme-catalyzed hydrolysis, the use of immobilized lipase results in high production cost. To address this problem, Eversa Transform lipase, a new and low-cost liquid lipase formulation, was used for the first time in oil hydrolysis with gac oil as a triglyceride source in this study. Response surface methodology was employed to optimize the reaction conditions and establish a reliable mathematical model for predicting hydrolysis yield. A maximal yield of 94.16% was obtained at a water-to-oil molar ratio of 12.79:1, reaction temperature of 38.9 degrees C, enzyme loading of 13.88%, and reaction time of 8.41 h. Under this optimal reaction condition, Eversa Transform lipase could be reused for up to eight cycles without significant loss in enzyme activity. This study indicates that the use of liquid Eversa Transform lipase in enzyme-catalyzed oil hydrolysis could be a promising and cheap method of fatty acid production.

AB - BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a multidimensional disease. In this study, we performed an unsupervised cluster analysis of CRSwNP using routinely available clinical markers. METHODS: We conducted a retrospective review of patients treated with endoscopic sinus surgery due to medically intractable bilateral CRSwNP from 2009 to 2017. Unsupervised cluster analysis was performed using a patient's clinical features, including age, peripheral blood eosinophil, tissue eosinophilia, Lund-Mackay computed tomography (CT) scores, ratio of the CT scores for the ethmoid sinus and maxillary sinus (E/M ratio), and comorbid asthma. Tree analysis was performed to develop a clustering algorithm. Kaplan-Meier survival analysis was performed to determine the revision surgery-free probability corresponding to each cluster. RESULTS: Data were available on 375 patients. Patients were categorized into 6 clusters comprising 2 asthmatic clusters and 4 non-asthmatic clusters. The labels for the 2 asthmatic clusters were: asthmatic non-eosinophilic polyp (cluster A1) and asthmatic eosinophilic polyp (cluster A2). The labels for the 4 non-asthmatic clusters were: non-eosinophilic polyp with older age (cluster NA1); non eosinophilic pol'yp with younger age (cluster NA2); eosinophilic polyp with lower E/M ratio (cluster NA3); and eosinophilic polyp with higher E/M ratio (cluster NA4). The 4-year revision-free rates were 100% (cluster NA1), 80.3% (NA2), 98.0% (NA3), 66.7% (NA4), 100% (A1), and 66.7% (A2). The clusters showed statistically significant differences in terms of 4-year revision-free rates (log-rank p < 0.05). CONCLUSION: Cluster analysis identified 2 asthmatic clusters and 4 non asthmatic clusters in CRSwNP. Each cluster corresponded to a different clinical outcome. PMID- 30281957 TI - The effect of feed quality due to clarification strategy on the design and performance of protein A periodic counter-current chromatography. AB - The impact of two different quality feeds, derived using two different harvest clarification processes, on protein A periodic counter-current chromatography (PCC) design and performance is investigated. Data from batch experiments were input into a model to design optimal PCC operating parameters specific to each feed material. The two clarification methods were: depth filtration using a wetlaid matrix which has Q-functionality; and a combination of depth filtration and chromatographic clarification, using a Q-functional nonwoven with a high anion exchange capacity (EmphazeTM AEX Hybrid Purifier) in which key impurities such as host cell DNA (HCDNA) and host cell proteins (HCP) are removed. The model predicted 34% better productivity for the chromatographically clarified cell culture fluid (CCCF) using a 4 column system, and productivity gains of 28% using only 3 columns enabling the option to simplify the protein A PCC strategy. Experimental validation of the predicted optimized PCC operating parameters using industrially relevant monoclonal antibody (mAb) CCCF feedstock over 100 cycles showed productivity gains of 49% for the chromatographically clarified material. HCP concentration was 11-fold lower, and HCDNA concentration was reduced by 4.4 Log Reduction Value (LRV) in the protein A PCC eluates. This work, therefore, demonstrates that the removal of HCDNA and HCP during clarification is an effective strategy for improving protein A PCC performance. This was achieved using the EmphazeTM AEX Hybrid Purifier which can be easily incorporated into a batch or continuous process, in a scalable fashion, without adding additional separate unit operations.

AB - The enantioselective hydrolysis of (R,S)-2,3-diphenylpropionic methyl ester ((R,S)-2,3-2-PPAME) catalyzed by lipase to (R)-2,3-diphenylpropionic acid ((R) 2,3-2-PPA) was studied in an aqueous system. The catalytic effects of different types of lipase were compared, and Candida antarctica lipase A (CALA) with higher catalytic activity and enantioselectivity was selected. Hydroxypropyl-beta cyclodextrin (HP-beta-CD) was added to the aqueous system to increase the solubility of 2,3-2-PPAME, which resulted in an increase of 35.56% in substrate conversion remaining the high enantiomeric excess. The factors influencing the substrate conversion and the optical purity of product such as temperature, pH, concentrations of CALA and HP-beta-CD, substrate loading, and reaction time were optimized. The optimal conditions for this reaction were obtained, including pH of 5.5, 30 mg/mL CALA, 25 mmol/L HP-beta-CD, 0.12 mmol substrate, temperature at 60 degrees C, agitation speed at 400 rpm, and 48 h for reaction time. Under these optimal conditions, the substrate conversion was up to 44.70% and the optical purity of the product (R)-2,3-2-PPA was up to 98.20%. This work provides an efficient alternative method for lipase-catalyzed enantioselective hydrolysis of 2,3-2-PPAME to (R)-2,3-2-PPA by beta-cyclodextrin inclusion in an aqueous reaction system of hydrolysis.

AB - This case reports the concurrence of gemination and fusion affecting the maxillary central incisors of a twelve-year-old patient and the collaboration of the pediatric dentist, endodontist, orthodontist and oral and maxillofacial surgeon. Developmental dental anomalies can occur in both primary and permanent dentitions as a result of conjoining defects. Double teeth, or cases of gemination or fusion, are not exceedingly rare, but the presence of both anomalies in a single patient is a rarity. Gemination is the division of a single tooth bud, resulting in a large single tooth with a bifid crown and common root and root canal. Fusion is the union of two separate tooth buds, resulting in a joined tooth with confluence of dentin and separate root canals. Labial apexogenesis with MTA, composite resin placement, re-contouring and orthodontic care allowed proper alignment with long-term monitoring of growth and development for possible incisor replacement.

This trend must be incorporated into existing fixed prosthodontics academic curricula through the integration of lithium disilicate and zirconium oxide crown preparation guidelines. In addition, crown fabrication techniques have also evolved for these newer materials through digitization of preparations and impressions and their computer-assisted manufacturing. This article reviews current crown preparation and cementation guidelines while describing the teaching program in fixed prosthodontics at the University of Tennessee Health Sciences College of Dentistry.

AB - Matriculation from the pre-clinical setting to the clinical environment is a tremendous accomplishment and exemplifies the student's perseverance in learning the fundamental concepts necessary for success in the clinical application of dentistry. In an effort to maximize its educational philosophy for the teaching program, the University of Tennessee's College of Dentistry has implemented Introduction to Clinical Practice I and II within the dental curriculum. Introduction to Clinical Practice I and II are designed to help the dental students effectively and smoothly transition to the clinical setting from the classroom and pre-clinical setting. This article describes the university's efforts and continuous improvements within the pre-clinical dental curriculum for advancing students to the clinics. The purpose of this article is to provide helpful information to other dental educational institutions on how to assist their pre-clinical dental students in transitioning to clinical student-doctors.

PMID- 30281972 TI - Role of the Conserved DECH-Box Cysteine in Coupling Hepatitis C Virus Helicase Catalyzed ATP Hydrolysis to RNA Unwinding. AB - DECH-box proteins are a subset of DExH/D-box superfamily 2 helicases possessing a conserved Asp-Glu-Cys-His motif in their ATP binding site. The conserved His helps position the Asp and Glu residues, which coordinate the divalent metal cation that connects the protein to ATP and activate the water molecule needed for ATP hydrolysis, but the role of the Cys is still unclear. This study uses site-directed mutants of the model DECH-box helicase encoded by the hepatitis C virus (HCV) to examine the role of the Cys in helicase action. Proteins lacking a Cys unwound DNA less efficiently than wild-type proteins did. For example, at low protein concentrations, a helicase harboring a Gly instead of the DECH-box Cys unwound DNA more slowly than the wild-type helicase did, but at higher protein concentrations, the two proteins unwound DNA at similar rates. All HCV proteins analyzed had similar affinities for ATP and nucleic acids and hydrolyzed ATP in the presence of RNA at similar rates. However, in the absence of RNA, all proteins lacking a DECH-box cysteine hydrolyzed ATP 10-15 times faster with higher Km values, and lower apparent affinities for metal ions, compared to those observed with wild-type proteins. These differences were observed with proteins isolated from HCV genotypes 2a and 1b, suggesting that this role is conserved. These data suggest the helicase needs Cys292 to bind ATP in a state where ATP is not hydrolyzed until RNA binds. PMID- 30281973 TI - Clearance in Drug Design. AB - Due to its implications for both dose level and frequency, clearance rate is one of the most important pharmacokinetic parameters to consider in the design of drug candidates. Clearance can be classified into three general categories, namely metabolic transformation, renal excretion and hepatobiliary excretion. Within each category, there are a host of biochemical and physiological mechanisms that ultimately determine the clearance rate. Physiochemical properties are often indicative of the rate-determining mechanism, with lipophilic molecules tending toward metabolism and hydrophilic, polar molecules tending toward passive or active excretion. Optimization of clearance requires recognition of the major clearance mechanisms and use of the most relevant in vitro and in vivo tools to develop structure-clearance relationships. The reliability of methods to detect and predict human clearance varies across mechanisms. While methods for metabolic and passive renal clearance have proven reasonably robust, there is a clear need for better tools to support the optimization of transporter-mediated clearance.

AB - The mechanism associated with the base-promoted conversion of alkoxy-substituted and ring-fused gem-dihalocyclopropanes such as 40 into annulated furans has been explored. Treatment of compound 40 with potassium tert-butoxide affords a mixture of furans 23/27 and 41, an outcome that suggests the intermediacy of the slowly interconverting carbonyl ylides 42 and 43 that undergo rapid [1,5] electrocyclizations and subsequent dehydrohalogenation to afford the observed products. This proposal is supported by ab initio MO and DFT calculations that also suggest a vinylcarbene insertion pathway is less likely to be operative. PMID- 30281975 TI - Cryo-EM Visualization of an Active High Open Probability CFTR Anion Channel. AB - The cystic fibrosis transmembrane conductance regulator (CFTR) anion channel, crucial to epithelial salt and water homeostasis, and defective due to mutations in its gene in patients with cystic fibrosis, is a unique member of the large family of ATP-binding cassette transport proteins. Regulation of CFTR channel activity is stringently controlled by phosphorylation and nucleotide binding. Structural changes that underlie transitions between active and inactive functional states are not yet fully understood. Indeed the first 3D structures of dephosphorylated, ATP-free, and phosphorylated ATP-bound states were only recently reported. Here we have determined the structure of inactive and active states of a thermally stabilized CFTR, the latter with a very high channel open probability, confirmed after reconstitution into proteoliposomes. These structures, obtained at nominal resolution of 4.3 and 6.6 A, reveal a unique repositioning of the transmembrane helices and regulatory domain density that provide insights into the structural transition between active and inactive functional states of CFTR. Moreover, we observe an extracellular vestibule that may provide anion access to the pore due to the conformation of transmembrane helices 7 and 8 that differs from the previous orthologue CFTR structures. In conclusion, our work contributes detailed structural information on an active, open state of the CFTR anion channel. PMID- 30281977 TI - Challenges and Benefits of Repurposing Licensed/Approved/Cleared Products for a Radiation Indication. AB - Increasingly, the risk of a radiological or nuclear public health emergency is a major concern for the U.S. government. To address a potential incident and ensure that the U.S. Government is prepared to respond to any civilian or military casualties that could result, the U.S. Department of Health and Human Services (HHS), together with the Department of Defense, has been charged with the development of medical countermeasures (MCMs) to treat individuals experiencing acute and delayed injuries that can result from exposure to radiation. With limited research and development budgets, and the high costs associated with bringing promising approaches from the bench through advanced product development activities, and ultimately, to regulatory approval, the U.S. Government places a priority on repurposing drugs that have already been commercialized for other indications in humans. To address the benefits and challenges of repurposing licensed products for a radiation indication, the National Institute of Allergy and Infectious Diseases convened a workshop with participants from U.S. Government agencies and industry, as well as academic subject matter experts. Topics included U.S. Government efforts (e.g., funding, regulatory, stockpiling and innovative ways to make drugs available for study), as well as the unique regulatory and other challenges faced when repurposing branded or generic drugs. PMID- 30281976 TI - A Mechanistic Investigation of Methylene Blue and Heparin Interactions and Their Photoacoustic Enhancement. AB - We recently reported a real-time method to measure heparin in human whole blood based on the photoacoustic change of methylene blue (MB). Intriguingly, the MB behaved unlike other "turn on" photoacoustic probes-the absorbance decreased as the photoacoustic signal increased. The underlying mechanism was not clear and motivated this study. We studied the binding mechanism of MB and heparin in water and phosphate buffer saline (PBS) with both experimental and computational methods. We found that the photoacoustic enhancement of the MB-heparin mixture was a result of MB-heparin aggregation due to charge neutralization and resulting sequestration of MB in these aggregates. The sequestration of MB in the MB heparin aggregates led to decreased absorbance-there was simply less free dye in solution to absorb light. The highest photoacoustic signal and aggregation occurred when the number of negatively charged sulfate groups on heparin was approximately equal to the number of positively charged MB molecule. The MB heparin aggregates dissociated when there were more sulfated groups from heparin than MB molecules because of the electrostatic repulsion between negatively charged sulfate groups. PBS facilitated MB dimer formation regardless of heparin concentration and reprecipitated free MB in aggregates due to ionic strength and ionic shielding. Further molecular dynamics experiments found that binding of heparin occurred at the sulfates and glucosamines in heparin. Phosphate ions could interact with the heparin via sodium ions to impair the MB-heparin binding. Finally, our model found 3.7-fold more MB dimerization upon addition of heparin in MB solution confirming that heparin facilitates MB aggregation. We conclude that the addition of heparin in MB decreases the absorbance of the sample because of MB-heparin aggregation leading to fewer MB molecules in solution; however, the aggregation also increases the PA intensity because the MB molecules in the MB heparin aggregate have reduced degrees of freedom and poor heat transfer to solvent. PMID- 30281978 TI - Promising vaccines for treating glioblastoma. AB - INTRODUCTION: Conventional therapies for glioblastoma (GBM) typically fail to provide lasting antitumor benefits, owing to their inability to specifically eliminate all malignant cells. Cancer vaccines are currently being evaluated as a means to direct the adaptive immune system to target residual GBM cells that remain following standard-of-care treatment. Areas covered: In this review, we provide an overview of the more noteworthy cancer vaccines that are under investigation for the treatment of GBM, as well as potential future directions that may enhance GBM-vaccine effectiveness. Expert opinion: To date, no cancer vaccines have been proven effective against GBM; however, only a few have reached phase III clinical testing. Clinical immunological monitoring data suggest that GBM vaccines are capable of stimulating immune responses reactive to GBM antigens, but whether these responses have an appreciable antitumor effect on GBM is still uncertain. Nevertheless, there have been several promising outcomes in early phase clinical trials, which lend encouragement to this area of study. Further studies with GBM vaccines are, therefore, warranted.

Here we report the epidemiology of a hospital outbreak of C. auris colonization and infection. METHODS: After identification of a cluster of C. auris infections in the neurosciences intensive care unit (ICU) of the Oxford University Hospitals, United Kingdom, we instituted an intensive patient and environmental screening program and package of interventions. Multivariable logistic regression was used to identify predictors of C. auris colonization and infection. Isolates from patients and from the environment were analyzed by whole-genome sequencing. RESULTS: A total of 70 patients were identified as being colonized or infected with C. auris between February 2, 2015, and August 31, 2017; of these patients, 66 (94%) had been admitted to the neurosciences ICU before diagnosis. Invasive C. auris infections developed in 7 patients. When length of stay in the neurosciences ICU and patient vital signs and laboratory results were controlled for, the predictors of C. auris colonization or infection included the use of reusable skin-surface axillary temperature probes (multivariable odds ratio, 6.80; 95% confidence interval [CI], 2.96 to 15.63; P<0.001) and systemic fluconazole exposure (multivariable odds ratio, 10.34; 95% CI, 1.64 to 65.18; P=0.01). C. auris was rarely detected in the general environment. However, it was detected in isolates from reusable equipment, including multiple axillary skin surface temperature probes. Despite a bundle of infection-control interventions, the incidence of new cases was reduced only after removal of the temperature probes. All outbreak sequences formed a single genetic cluster within the C. auris South African clade. The sequenced isolates from reusable equipment were genetically related to isolates from the patients. CONCLUSIONS: The transmission of C. auris in this hospital outbreak was found to be linked to reusable axillary temperature probes, indicating that this emerging pathogen can persist in the environment and be transmitted in health care settings.

AB - BACKGROUND: The dynamics of body-mass index (BMI) in children from birth to adolescence are unclear, and whether susceptibility for the development of sustained obesity occurs at a specific age in children is important to determine. METHODS: To assess the age at onset of obesity, we performed prospective and retrospective analyses of the course of BMI over time in a population-based sample of 51,505 children for whom sequential anthropometric data were available during childhood (0 to 14 years of age) and adolescence (15 to 18 years of age). In addition, we assessed the dynamics of annual BMI increments, defined as the change in BMI standard-deviation score per year, during childhood in 34,196 children. RESULTS: In retrospective analyses, we found that most of the adolescents with normal weight had always had a normal weight throughout childhood. Approximately half (53%) of the obese adolescents had been overweight or obese from 5 years of age onward, and the BMI standard-deviation score further increased with age. In prospective analyses, we found that almost 90% of the children who were obese at 3 years of age were overweight or obese in adolescence. Among the adolescents who were obese, the greatest acceleration in annual BMI increments had occurred between 2 and 6 years of age, with a further rise in BMI percentile thereafter. High acceleration in annual BMI increments during the preschool years (but not during the school years) was associated with a risk of overweight or obesity in adolescence that was 1.4 times as high as the risk among children who had had stable BMI. The rate of overweight or obesity in adolescence was higher among children who had been large for gestational age at birth (43.7%) than among those who had been at an appropriate weight for gestational age (28.4%) or small for gestational age (27.2%), which corresponded to a risk of adolescent obesity that was 1.55 times as high among those who had been large for gestational age as among the other groups. CONCLUSIONS: Among obese adolescents, the most rapid weight gain had occurred between 2 and 6 years of age; most children who were obese at that age were obese in adolescence.

AB - Risperidone, one of the second-generation antipsychotics, can efficiently target dopamine D2 and serotonin 5-HT2A receptors. There actually exists significant implication of CYP2D6 genetic polymorphisms on the metabolic kinetics of risperidone, little is known about the extent of CYP2D6 impacting human D2 and 5 HT2A receptor occupancies as well as the clinical efficacy and efficacy in schizophrenia treatment. Here we assessed the influences of CYP2D6 gene polymorphisms on human target occupancies/clinical outcomes and optimized the maintenance therapy of risperidone. A translational framework, previously developed using in vitro and in vivo information in rats, was used as the basis for integrating the effects of CYP2D6 genetic polymorphisms on target occupancies and clinical outcomes. D2 occupancy as a biomarker was related to Positive and Negative Syndrome Scale (PANSS) response and Simpson-Angus Scale (SAS). The population approach was applied to characterize pharmacokinetic and pharmacodynamic (PK/PD) profiles of risperidone. Non-compartment analysis method was performed to calculate the steady state PK/PD parameters of both risperidone and 9-hydroxyrisperidone. The predictive power of this extended translational framework was determined by comparing the predictions of target occupancies and clinical outcomes with the reported human values of risperidone at clinically suggested dosage of 4.0 mg/day. This extended translational framework was adequately used to predict human target occupancies and clinical outcomes. At the steady state, D2 ROs were 75.8%, 79.3% and 86.0% for CYP2D6 poor metabolizer (PM), intermediate metabolizer (IM) and extensive metabolizer (EM), respectively; 5-HT2A ROs were 96.4%, 97.2% and 98.4% for CYP2D6 PM, IM and EM, respectively; PANSS changes from placebo were -5.3, -7.7 and -11.3 for CYP2D6 PM, IM and EM, respectively; SAS changes from placebo were 0.13, 0.15 and 0.18 for CYP2D6 PM, IM and EM, respectively. The predictions of human D2, 5-HT2A RO, PANSS and SAS changes for risperidone with CYP2D6 genetic polymorphisms were well in line with the reported values in clinic. 5.0, 4.0 and 2.5 mg/day were the equivalent dosages of risperidone for CYP2D6 PM, IM and EM, respectively. The optimized maintenance therapy of risperidone was provided through the Three-Step method and the dosage range was 2.5-5.0 mg/day for three CYP2D6 gene groups in the present study. Taken together, our findings demonstrate that this extended translational framework not only differentiates the effects of CYP2D6 genetic polymorphisms on target occupancies and clinical outcomes, but also constitutes a scientific basis to optimize the maintenance therapy of neuropsychiatric patients in clinic. PMID- 30282000 TI - Presence of human herpes virus 1-thymidine kinase in testis of azoospermic infertile herpes-infected patients. AB - Infection with human herpes virus 1 (HHV1) is a suspected cause of human male infertility. However, the correlation between HHV1 infection and infertility is still unclear. We have previously generated transgenic rats that ectopically express the HHV1 thymidine kinase gene (HHV1-TK) in post-meiotic spermatids and found they had aberrant spermatogenesis and infertility. Therefore, we hypothesized that human infertility might be caused by HHV1 infection. Here, we examined whether HHV1-TK is expressed in human testis by analyzing the presence of its transcript and protein. Specimens were collected by biopsy from 30 azoospermic infertile male patients. RT-PCR and immunohistochemistry showed that 23 patients were positive for HHV1-TK expression, while seven patients were negative. Thus, we demonstrated HHV1-TK expression, indicating HHV1 infection, in the testis of human azoospermic infertile males for the first time; our findings represent a great advancement toward the verification of our hypothesis that HHV1 TK expression might cause human infertility. PMID- 30282001 TI - Different aspects of platelet evaluation in dengue: Measurement of circulating mediators, ability to interact with the virus, the degree of activation and quantification of intraplatelet protein content. AB - Platelets play a role in hemostasis, coagulation, angiogenesis, inflammation and immune response is one of the most affected cells in dengue. Here we describe some aspects of platelets by observing their specific circulating mediators, the ability to interact with the virus and morphological consequences of this interaction, activation markers and intraplatelet protein contents in dengue. We conducted this study using dengue-patients as well as healthy donors. Immunoenzymatic assay, flow cytometry, transmission electron microscopy and intraplatelet proteins expression assays were carried out. Briefly, we found an increase in sCD62L, NO or TBX2 ratio in platelet count, mostly in patients with the worse clinical outcome. After in vitro DENV infection or during natural infection, platelets underwent morphological alteration with increased expression of platelet activation markers, particularly in natural infections. Analysis of intraplatelet protein contents revealed different angiogenic and inflammatory profiles, maintaining or not extracellular matrix integrity between DF and DFWS patients. Thus, platelets are frequently affected by dengue, either by altering their own functionality, as "carrier" of the virus, or as an antiviral and mediator-secreting effector cell. Thus, strategies aimed at recovering platelet amounts in dengue seem to be essential for a better clinical outcome of the patients. PMID- 30282002 TI - Effects of Chronic Spinal Cord Injury on Relationships among Ion Channel and Receptor mRNAs in Mouse Lumbar Spinal Cord. AB - Spinal cord injury (SCI) causes widespread changes in gene expression of the spinal cord, even in the undamaged spinal cord below the level of the lesion. Less is known about changes in the correlated expression of genes after SCI. We investigated gene co-expression networks among voltage-gated ion channel and neurotransmitter receptor mRNA levels using quantitative RT-PCR in longitudinal slices of the mouse lumbar spinal cord in control and chronic SCI animals. These longitudinal slices were made from the ventral surface of the cord, thus forming slices relatively enriched in motor neurons or interneurons. We performed absolute quantitation of mRNA copy number for 50 ion channel or receptor transcripts from each sample, and used multiple correlation analyses to detect patterns in correlated mRNA levels across all pairs of genes. The majority of channels and receptors changed in expression as a result of chronic SCI, but did so differently across slice levels. Furthermore, motor neuron-enriched slices experienced an overall loss of correlated channel and receptor expression, while interneuron slices showed a dramatic increase in the number of positively correlated transcripts. These correlation profiles suggest that spinal cord injury induces distinct changes across cell types in the organization of gene co expression networks for ion channels and transmitter receptors. PMID- 30282003 TI - Seasonal and spatial distribution of Aedes aegypti and Aedes albopictus in a municipal urban park in Sao Paulo, SP, Brazil. AB - Dengue, yellow fever, chikungunya and Zika are important arboviruses present in various countries of the world, the etiological agents of which are transmitted to human-beings by the bite of infected females of Aedes aegypti and Aedes albopictus. Biological aspects of these vectors, such as their distribution and abundance, are influenced by climatic variables such as rainfall and temperature. We assess the spatial and seasonal distribution of Ae. aegypti and Ae. albopictus, during spring 2014 and spring 2015 and autumn 2015 and autumn 2016, in an urban Municipal Park, Sao Paulo (SP, Brazil), using 36 ovitraps. The Park was divided into three areas: internal, intermediate and peripheral, and 12 geo referenced ovitraps were randomly installed in each area. We evaluated the association between the environmental variables maximum and minimum temperatures and rainfall with oviposition rates in the park using negative binomial regression models. Further, to estimate the distribution of the species in the three areas during the seasons, we employed the geostatic interpolation method with the use of kriging. Our results show the presence of the two species in the area in both the seasons but with a greater predominance of Ae. albopictus. Both species were significantly more abundant in spring than autumn. However, our results suggested that this seasonal variation was mediated by the maximum and minimum temperatures, which were significantly associated with the oviposition rate of both species, in all regression models. Cumulative rainfall of the week of collection was not associated with the abundance of the vectors in the multiple models. Moreover, regardless of climatic variables, the oviposition of Ae. aegypti was positively associated with the peripheral area of the park compared with the internal area (oviposition rate ratio [ORR]: 4.92; 95% CI: 2.46 9.83). On the other hand, the oviposition of Ae. albopictus was negatively associated with the peripheral area as compared with the internal one (ORR: 0.59; 95% CI: 0.38-0.91). The spatial distribution revealed a pattern of spatial segregation, confirming the ecological preferences of each species. Green areas in urban centers can serve as important habitats for various mosquito species, including especially Ae. albopictus. Thus it is that our study highlights the importance of maintaining surveillance for the targeting of control strategies in green areas as well, since most control strategies are focused on Ae. aegypti and urban residential centers. PMID- 30282004 TI - Clustering-based multi-view network fusion for estimating brain network atlases of healthy and disordered populations. AB - BACKGROUND: While several research methods were developed to estimate individual based representations of brain connectional wiring (i.e., a connectome), traditionally captured using multimodal MRI data (e.g., functional and diffusion MRI), very limited works aimed to estimate brain network atlas for a population of connectomes. Estimating well-representative brain templates is a key step for group comparison studies. However, estimating a network atlas for a population of multi-source brain connectomes lying on different manifolds is absent. NEW METHOD: To fill this gap, we propose a cluster-based multi-view brain connectivity fusion framework to estimate a brain network atlas for a population of multi-view brain networks, where each view captures a specific facet of the brain construct. Specifically, given a population of subjects, each with multi view networks, we first non-linearly fuse multi-view networks into a single fused network for each subject. Then, we cluster the fused networks to identify individuals sharing similar connectional traits in an unsupervised way, which are next averaged within each cluster to generate a representative network atlas. Finally, we construct the final multi-view network atlas by averaging the obtained templates of all clusters. RESULTS: We evaluated our method on both healthy and disordered populations (with autism and dementia) and spotted differences between network atlases for healthy and autistic groups. COMPARISON WITH EXISTING METHODS AND CONCLUSIONS: Compared to other baseline methods, our fusion strategy achieved the best results in terms of template centeredness and population representativeness. PMID- 30282005 TI - Paracetamol-induced liver injury modelled in Xenopus laevis embryos. AB - INTRODUCTION: Failure to predict drug-induced liver injury (DILI) remains a major contributing factor to lead compound drop-out during drug development. Xenopus embryos are amenable for early stage medium throughput small molecule screens and so have the potential to be used in pre-clinical screens. To begin to assess the usefulness and limitations of Xenopus embryos for safety assessment in the early phases of drug development, paracetamol was used as a model hepatotoxin. Paracetamol overdose is associated with acute liver injury. In mammals, the main mechanism of paracetamol-induced acute liver injury is an increased amount of the reactive metabolite N-acetyl-p-benzoquinone imine (NAPQI) combined with a reduction of free glutathione (GSH). Humans that have taken an overdose of paracetamol are often treated with N-acetyl cysteine (NAC). METHOD: Xenopus laevis embryos were treated with up to 5 mM paracetamol from stage 38 to stage 45 during development, when the liver is functional. The presence of paracetamol induced liver injury was assessed by: (Dart et al., 2006) microRNA-122 (miR-122) expression (a hepatic marker), (Jaeschke, 2015) free GSH concentration (a marker of oxidative stress) and (Larson et al., 2005) NAC antioxidant intervention. RESULTS: The amount of free GSH decreased significantly in embryos exposed to increasing paracetamol concentration. In embryos exposed to 5 mM paracetamol, 22.57 +/- 4.25 nmol/mg GSH was detected compared to 47.11 +/- 7.31 nmol/mg untreated embryos (mean +/- SEM). In tail tissue, miRNA-122 expression increased 6.3-fold with 3 mM paracetamol concentration treatment compared to untreated embryos. NAC treatment altered the free GSH decline for embryos treated with up to 5 mM. Embryos exposed to 1 mM paracetamol and then exposed to 0.5 mM NAC 24 h prior to harvest, had an significantly higher amount GSH compared to embryos that were only exposed to 1 mM paracetamol (mean +/- SEM; 97.1 +/- 9.6 nmol/mg and 54.5 +/- 6.6 nmol/mg respectively). CONCLUSION: Xenopus laevis embryos exhibit similar characteristics of paracetamol-induced liver injury observed in mammalian models. These data indicate that the Xenopus embryo could be a useful in vivo model to assess DILI and aid lead compound prioritisation during the early phase of drug development, in combination with pre-clinical in vitro studies. Consequently, the Xenopus embryo could contribute to the reduction principle as defined by the National Centre for the Replacement, Refinement and Reduction of Animals in Research. PMID- 30282006 TI - In vitro human skin permeation and decontamination of diisopropyl methylphosphonate (DIMP) using Dermal Decontamination Gel (DDGel) and Reactive Skin Decontamination Lotion (RSDL) at different timepoints. AB - This study compared the efficiency for in vitro human skin decontamination using DDGel and RSDL when applied at different timepoints (5 min and 90 min). Experiments were performed using in vitro human skin models, in which skin was mounted onto Flow-Through diffusion cells. The mass of 14-C DIMP removed from skin surface after decontamination was quantitated by measuring radioactivity with a liquid scintillation spectrometer. Both decontaminants removed more than 90% recovery dose of DIMP from skin compared to control group (p < 0.05). DDGel skin decontamination reduced more toxicant amount when compared to RSDL. DDGel showed slight higher decontamination ability of DIMP than RSDL and efficiently removed chemicals from the skin surface, also reduced the amount of DIMP in receptor fluid. A similar decontamination regimen with RSDL and DDGel at 90 min showed that both were still might effectively increase the time window of opportunity for treatment. Thus, DDGel can offer a potential as a next generation skin decontamination platform technology for military and civilian applications.

AB - Maternal exposure to lipopolysaccharide (LPS), a bacterial endotoxin produced during infection, leads to disruption in fetal brain development and causes newborn brain injury. Quercetin (QR) is a multipotent flavonoid that functions as an antioxidant and protects against inflammation and neurodegeneration. In this study, we explored the potential functions of QR in alleviating maternal LPS exposure induced fetal brain damage. Pregnant rats at late gestational stages were treated with saline, LPS, QR, LPS and QR. Brain injury biomarker TGF-1beta was assessed in cerebrospinal fluid (CSF) and brain tissue of newborn rats. Pro inflammatory cytokines, apoptosis markers and oxidative stress indicators were evaluated. We found that LPS treatment induced an increased production of TGF 1beta which was suppressed by QR administration. LPS enhanced pro-apoptotic Bax and inhibited anti-apoptotic Bcl-2 expression. QR reduced that ratio of Bax and Bcl-2 that was high in LPS treated brain tissue. Additionally, QR suppressed oxidative stress induced by LPS. Finally, QR reduced the levels of pro inflammatory cytokines that were produced as a result of LPS exposure. In summary, our study indicates that QR potently alleviates maternal LPS exposure induced fetal brain injury in rats, making it a potential therapeutic for suppressing infant brain damage as a result of maternal infection. PMID- 30282007 TI - Towards microstructure fingerprinting: Estimation of tissue properties from a dictionary of Monte Carlo diffusion MRI simulations. AB - Many closed-form analytical models have been proposed to relate the diffusion weighted magnetic resonance imaging (DW-MRI) signal to microstructural features of white matter tissues. These models generally make assumptions about the tissue and the diffusion processes which often depart from the biophysical reality, limiting their reliability and interpretability in practice. Monte Carlo simulations of the random walk of water molecules are widely recognized to provide near groundtruth for DW-MRI signals. However, they have mostly been limited to the validation of simpler models rather than used for the estimation of microstructural properties. This work proposes a general framework which leverages Monte Carlo simulations for the estimation of physically interpretable microstructural parameters, both in single and in crossing fascicles of axons. Monte Carlo simulations of DW-MRI signals, or fingerprints, are pre-computed for a large collection of microstructural configurations. At every voxel, the microstructural parameters are estimated by optimizing a sparse combination of these fingerprints. Extensive synthetic experiments showed that our approach achieves accurate and robust estimates in the presence of noise and uncertainties over fixed or input parameters. In an in vivo rat model of spinal cord injury, our approach provided microstructural parameters that showed better correspondence with histology than five closed-form models of the diffusion signal: MMWMD, NODDI, DIAMOND, WMTI and MAPL. On whole-brain in vivo data from the human connectome project (HCP), our method exhibited spatial distributions of apparent axonal radius and axonal density indices in keeping with ex vivo studies. This work paves the way for microstructure fingerprinting with Monte Carlo simulations used directly at the modeling stage and not only as a validation tool. PMID- 30282010 TI - Evaluation of the mucoadhesive properties of chitosan nanoparticles prepared using different chitosan to tripolyphosphate (CS:TPP) ratios. AB - Mucoadhesive molecules such as chitosan, can allow targeting of a particular tissue to prolong residence time and subsequently improve bioavailability. The purpose of this study was to investigate chitosan-tripolyphosphate (CS:TPP) nanoparticles and to evaluate the interaction between nanoparticles of different CS:TPP ratios with mucin using viscosity, particle size analysis and zeta potential. For all CS:TPP ratios examined, a minimum value of viscosity was reached for a 3:1 CS:TPP ratio, however chitosan nanoparticles at this ratio were not stable (<+30 mV), whereas a CS:TPP ratio of 4:1 displayed the strongest interaction. This suggests a minimum CS:TPP ratio of 4:1 is required to produce stable nanoparticles able to form strong interactions, which is consistent with a greater mucin binding efficiencies at CS:TPP ratios of 4:1 and higher, which were quantified using a colorimetric assay. Further analysis of similar systems could lead potentially to tuneable chitosan nanoparticles for specific applications. PMID- 30282011 TI - Rehmannia glutinosa polysaccharide functions as a mucosal adjuvant to induce dendritic cell activation in mediastinal lymph node. AB - In our previous study, we showed that Rehmannia glutinosa polysaccharide (RGP) treatment induced activation of dendritic cells (DCs) in human and mouse subjects. In this study, we evaluated the effect of RGP as a mucosal adjuvant for inducting activation of DCs in the mediastinal lymph node (mLN) in the mouse. The C57BL/6 mice were intranasally (i.n.) treated with RGP and activation of DC in the mLN was analyzed. The treatment with RGP induced a substantial increase in the number of DCs in the mLN due to the up-regulation of C-C motif chemokine receptor 7 (CCR7) in the DCs. Moreover, the expression of co-stimulatory molecules in the mLN DCs and the concentration of pro-inflammatory cytokines in the lung were up-regulated by RGP treatment. Also, RGP treatment induced interferon-gamma (IFN-gamma) and tumor necrosis factor-alpha (TNF-alpha) production in the mLN T cells. The combination treatment of RGP and ovalbumin (OVA) induced OVA-specific TCR transgenic I (OT-I) and OT-II cell proliferation in the mLN. Finally, the combination treatment of RGP and tyrosinase-related protein 2 (TRP2) peptide, a melanoma self-antigen, protected mice from melanoma challenge. Thus, these data demonstrated that RGP can be used as a mucosal adjuvant for inducing activation of immune responses in the lung.

The crude polysaccharide was extracted with the hot-water. It proved that the CaCl2 method was very suitable for deproteinization to cushaw polysaccharide. The cushaw polysaccharide contained alpha/beta glycosidic bonds. Moreover, it proved that the cushaw polysaccharide exhibited better antioxidant activities. PMID- 30282009 TI - Impact of obesity on the toxicity of a multi-ingredient dietary supplement, OxyELITE ProTM (New Formula), using the novel NZO/HILtJ obese mouse model: Physiological and mechanistic assessments. AB - Herbal dietary supplement (HDS)-induced hepato- and cardiotoxicity is an emerging clinical problem. In this study, we investigated the liver and heart toxicity of HDS OxyELITE-PROTM New Formula (OEP-NF), a dietary supplement marketed for weight loss and performance enhancement that was recently withdrawn from the market. Using a novel NZO/HlLtJ obese mouse model, we demonstrated that administration of clinically relevant mouse equivalent doses (MED) of OEP-NF produced cardio- and hepatotoxic risks following both short- and long-term administration schedules. Specifically, gavaging female NZO/HlLtJ with up to 2X MED of OEP-NF resulted in 40% mortality within two weeks. Feeding mice with either 1X or 3X MED of OEP-NF for eight weeks, while not exhibiting significant effects on body weights, significantly altered hepatic gene expression, increased the number of apoptotic and mast cells in the heart and affected cardiac function. The degree of toxicity in NZO/HlLtJ mice was higher than that observed previously in non-obese CD-1 and B6C3F1 strains, suggesting that an overweight/obese condition can sensitize mice to OEP-NF. Adverse health effects linked to OEP-NF, together with a number of other hepato- and cardiotoxicity cases associated with HDS ingestion, argue strongly for introduction of quality standards and pre-marketing safety assessments for multi-ingredient HDS. PMID- 30282013 TI - Chitosan/Ag-hydroxyapatite nanocomposite beads as a potential adsorbent for the efficient removal of toxic aquatic pollutants. AB - In the present study, the potential of synthesized chitosan/Ag-substituted hydroxyapatite nanocomposite beads to remove basic dye, heavy metal and microbes from aqueous solutions was investigated. Beads were prepared in different ratios via embedding of Ag-hydroxyapatite (Ag-HA) into chitosan (CS) solution. The beads were characterized by Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscope (SEM) in order to get an insight of the functional groups and morphology. Batch adsorption studies were conducted with copper ions (Cu (II)) and rhodamine B (RhB) dye by changing several parameters such as Ag-HA to Cs ratio, contact time, solution pH and initial concentration of pollutants. The antibacterial efficiency of beads was tested under dynamic contact conditions against commonly found bacteria in water, Escherichia coli. The adsorption isotherm data were best fitted with Langmuir model. The maximum Langmuir adsorption capabilities for Cu (II) ions and rhodamine B were found to be 40.11 mg/g and 127.61 mg/g, respectively. The adsorption process could be best described by pseudo-second-order kinetic model for both rhodamine B and Cu(II). The percentage removal efficiency of Cu (II) and rhodamine B from tap water and untreated river water ranged from 86.7 to 94.4% along with 99.99% of decontamination of microbial load. PMID- 30282014 TI - Comparison of the effects of calcified green macroalga (Halimeda macroloba Decaisne) and commercial CaCO3 on the properties of composite starch foam trays. AB - The calcified green macroalga, Halimeda macroloba, is a source of bio-based calcium carbonate which can be used as a filler in starch foam tray. In the first part of this study, the composition and structure of calcium carbonate of this species were investigated using Fourier transform infrared spectrometry (FTIR), X ray diffraction (XRD), Energy dispersive X-ray spectroscopy (EDX) and Scanning election microscopy (SEM). The morphology of the macroalgal powder particles was rod-like and organic materials (e.g. polysaccharide) and calcium carbonate (aragonite form) were present. The second part of the study investigated the effects of calcium carbonate from H. macroloba on the properties of starch foam tray and compared them with the properties of starch foam tray filled with commercial CaCO3. Interestingly, the composites starch foam trays with macroalgal powder had better impact strength than starch/commercial CaCO3 composite foam trays. Moreover, the macroalgal powder affected the thermal properties of the starch foam tray equally as well as commercial CaCO3. However, the macroalgal powder caused more significant changes in the color parameters and the whiteness values of starch foam tray than commercial CaCO3. PMID- 30282015 TI - Development of a mass spectrometry method for the characterization of a series of chitosan. AB - Chitosan has multiple biological activities, but a sensitive and rapid characterization method is yet to be developed for its further application. This study presented an optional mass spectrometry method for the characterization of chitosan. Nine kinds of chitosan (degree of deacetylation (DD), 63.08%-89.06% & MW, 106.1-485.0 kDa) were adopted for the method development. Most species of chitosan, detected by an ESI-MS technique, were observed below 1000 m/z, which seemed that only chito-oligosaccharide (COS) impurities were detected. Then, a sensitive UPLC-ESI-MS/MS method was established to assess the COS impurities in chitosan, and no COS impurities were detected. However, dissociation of chitosan and COSs in the ESI source were observed, and then the mass spectra patterns were deeply evaluated via an accurate Q-TOF mass spectrometer. Our research demonstrated that the mass spectra of COSs and chitosan resulted from the dissociation of glycosidic linkage and dehydration. Although the distribution of GlcN and GlcNAc units in these chitosan samples might be different, similar dissociation efficiencies were observed. Furthermore, good linearities were obtained between the intensities of product ions, detected by an UPLC-pseuedo-MS2 method, and DDs determined by conventional method. This method could be suitable for the DD determination and quantitative analysis of chitosan. PMID- 30282016 TI - Virus Assembly Antagonists from Redesigned Antibodies.

AB - In this issue of Structure, Pulido et al. (2018) determine the crystal structure of procollagen C-proteinase enhancer-1 (PCPE-1)/procollagen III complex and identify that PCPE-1 unwinds the stalk of the procollagen III trimer, liberating a single chain to facilitate binding and cleavage by BMP-1 proteinases for subsequent fibrillar collagen assembly. PMID- 30282018 TI - The time course of blood brain barrier leakage and its implications on the progression of methamphetamine-induced seizures. AB - The initial goals of these experiments were to determine: 1) if blood-brain barrier (BBB) breakdown was a cause or an effect of METH-induced seizures; 2) all the brain regions where BBB is disrupted as seizures progress; and 3) the correlations between body temperature and vascular leakage and neurodegeneration. A fourth objective was added after initial experimentation to determine if sub strain differences existed in adult male C57 B6 J (Jackson laboratories, JAX) versus C57 B6N (Charles River, CR) mice involving their susceptibility to BBB breakdown and seizure severity. With the 1st "maximal" intensity myoclonic-tonic seizure (MCT) varying degrees of IgG infiltration across the BBB (<=1 mm2) were prominent in olfactory system (OS) associated regions and in thalamus, hypothalamus and neocortex. IgG infiltration areas in the OS-associated regions of the bed nucleus of the stria terminalis, septum and more medial amygdala nuclei, and the hypothalamus were increased significantly by the time continuous behavioral seizures (CBS) developed. Mice receiving METH that had body temperatures of >=40 degrees C had IgG infiltration along with MCT or CBS but peak body temperatures above 40 degrees C did not significantly increase IgG infiltration. Neurodegeneration seen at >=6 h was restricted to the OS in both JAX and CR mice and was most prominent in the posteromedial cortical amygdaloid nucleus. Neurodegeneration in the anterior septum (tenia tecta) was seen only in the JAX mice. We hypothesize that METH-induced hypertension and hyperthermia lead to BBB breakdown and other vascular dysfunctions in the OS brain regions resulting in OS hyperexcitation. Excitation of the OS neural network then leads to the development of seizures. These seizures in turn exacerbate the energy depletions and the reactive oxygen stress produced by hyperthermia further damaging the BBB and vascular function. These events form a recurrent cycle that results in ever increasing seizure activity and neurotoxicity. PMID- 30282019 TI - Cell-Autonomous Regulation of Astrocyte Activation by the Circadian Clock Protein BMAL1. AB - Circadian clock dysfunction is a common symptom of aging and neurodegenerative diseases, though its impact on brain health is poorly understood. Astrocyte activation occurs in response to diverse insults and plays a critical role in brain health and disease. We report that the core circadian clock protein BMAL1 regulates astrogliosis in a synergistic manner via a cell-autonomous mechanism and a lesser non-cell-autonomous signal from neurons. Astrocyte-specific Bmal1 deletion induces astrocyte activation and inflammatory gene expression in vitro and in vivo, mediated in part by suppression of glutathione-S-transferase signaling. Functionally, loss of Bmal1 in astrocytes promotes neuronal death in vitro. Our results demonstrate that the core clock protein BMAL1 regulates astrocyte activation and function in vivo, elucidating a mechanism by which the circadian clock could influence many aspects of brain function and neurological disease. PMID- 30282020 TI - Mutations in Craniosynostosis Patients Cause Defective Interleukin-11 Receptor Maturation and Drive Craniosynostosis-like Disease in Mice. AB - Premature closure of the sutures that connect the cranial bones during development of the mammalian skull results in a phenotype called craniosynostosis. Recently, several craniosynostosis patients with missense mutations within the gene encoding the interleukin-11 receptor (IL-11R) have been described, but the underlying molecular mechanisms have remained elusive. IL-11 is a cytokine that has a crucial role in bone remodeling and activates cells via binding to the IL-11R. Here, we show that patient mutations prevented maturation of the IL-11R, resulting in endoplasmic reticulum retention and diminished cell surface appearance. Disruption of a conserved tryptophan-arginine zipper within the third domain of the IL-11R was the underlying cause of the defective maturation. IL-11 classic signaling via the membrane-bound receptor, but not IL 11 trans-signaling via the soluble receptor, was the crucial pathway for normal skull development in mice in vivo. Thus, the specific therapeutic inhibition of IL-11 trans-signaling does not interfere with skull development. PMID- 30282021 TI - Single-Cell Analysis of Quiescent HIV Infection Reveals Host Transcriptional Profiles that Regulate Proviral Latency. AB - A detailed understanding of the mechanisms that establish or maintain the latent reservoir of HIV will guide approaches to eliminate persistent infection. We used a cell line and primary cell models of HIV latency to investigate viral RNA (vRNA) expression and the role of the host transcriptome using single-cell approaches. Single-cell vRNA quantitation identified distinct populations of cells expressing various levels of vRNA, including completely silent populations. Strikingly, single-cell RNA-seq of latently infected primary cells demonstrated that HIV downregulation occurred in diverse transcriptomic environments but was significantly associated with expression of a specific set of cellular genes. In particular, latency was more frequent in cells expressing a transcriptional signature that included markers of naive and central memory T cells. These data reveal that expression of HIV proviruses within the latent reservoir are influenced by the host cell transcriptional program. Therapeutic modulation of these programs may reverse or enforce HIV latency. PMID- 30282022 TI - Type I Interferon Receptor Signaling of Neurons and Astrocytes Regulates Microglia Activation during Viral Encephalitis. AB - In sterile neuroinflammation, a pathological role is proposed for microglia, whereas in viral encephalitis, their function is not entirely clear. Many viruses exploit the odorant system and enter the CNS via the olfactory bulb (OB). Upon intranasal vesicular stomatitis virus instillation, we show an accumulation of activated microglia and monocytes in the OB. Depletion of microglia during encephalitis results in enhanced virus spread and increased lethality. Activation, proliferation, and accumulation of microglia are regulated by type I IFN receptor signaling of neurons and astrocytes, but not of microglia. Morphological analysis of myeloid cells shows that type I IFN receptor signaling of neurons has a stronger impact on the activation of myeloid cells than of astrocytes. Thus, in the infected CNS, the cross talk among neurons, astrocytes, and microglia is critical for full microglia activation and protection from lethal encephalitis. PMID- 30282025 TI - Visual Motion Processing in Macaque V2. AB - In the primate visual system, direction-selective (DS) neurons are critical for visual motion perception. While DS neurons in the dorsal visual pathway have been well characterized, the response properties of DS neurons in other major visual areas are largely unexplored. Recent optical imaging studies in monkey visual cortex area 2 (V2) revealed clusters of DS neurons. This imaging method facilitates targeted recordings from these neurons. Using optical imaging and single-cell recording, we characterized detailed response properties of DS neurons in macaque V2. Compared with DS neurons in the dorsal areas (e.g., middle temporal area [MT]), V2 DS neurons have a smaller receptive field and a stronger antagonistic surround. They do not code speed or plaid motion but are sensitive to motion contrast. Our results suggest that V2 DS neurons play an important role in figure-ground segregation. The clusters of V2 DS neurons are likely specialized functional systems for detecting motion contrast. PMID- 30282023 TI - Transsynaptic Binding of Orphan Receptor GPR179 to Dystroglycan-Pikachurin Complex Is Essential for the Synaptic Organization of Photoreceptors. AB - Establishing synaptic contacts between neurons is paramount for nervous system function. This process involves transsynaptic interactions between a host of cell adhesion molecules that act in cooperation with the proteins of the extracellular matrix to specify unique physiological properties of individual synaptic connections. However, understanding of the molecular mechanisms that generate functional diversity in an input-specific fashion is limited. In this study, we identify that major components of the extracellular matrix proteins present in the synaptic cleft-members of the heparan sulfate proteoglycan (HSPG) family associate with the GPR158/179 group of orphan receptors. Using the mammalian retina as a model system, we demonstrate that the HSPG member Pikachurin, released by photoreceptors, recruits a key post-synaptic signaling complex of downstream ON-bipolar neurons in coordination with the pre-synaptic dystroglycan glycoprotein complex. We further demonstrate that this transsynaptic assembly plays an essential role in synaptic transmission of photoreceptor signals. PMID- 30282024 TI - Sub-populations of Spinal V3 Interneurons Form Focal Modules of Layered Pre-motor Microcircuits. AB - Layering of neural circuits facilitates the separation of neurons with high spatial sensitivity from those that play integrative temporal roles. Although anatomical layers are readily identifiable in the brain, layering is not structurally obvious in the spinal cord. But computational studies of motor behaviors have led to the concept of layered processing in the spinal cord. It has been postulated that spinal V3 interneurons (INs) play multiple roles in locomotion, leading us to investigate whether they form layered microcircuits. Using patch-clamp recordings in combination with holographic glutamate uncaging, we demonstrate focal, layered modules, in which ventromedial V3 INs form synapses with one another and with ventrolateral V3 INs, which in turn form synapses with ipsilateral motoneurons. Motoneurons, in turn, provide recurrent excitatory, glutamatergic input to V3 INs. Thus, ventral V3 interneurons form layered microcircuits that could function to ensure well-timed, spatially specific movements. PMID- 30282026 TI - Activity-Dependent Netrin-1 Secretion Drives Synaptic Insertion of GluA1 Containing AMPA Receptors in the Hippocampus. AB - Dynamic trafficking of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid glutamate receptors (AMPARs) to synapses is critical for activity-dependent synaptic plasticity underlying learning and memory, but the identity of key molecular effectors remains elusive. Here, we demonstrate that membrane depolarization and N-methyl-D-aspartate receptor (NMDAR) activation triggers secretion of the chemotropic guidance cue netrin-1 from dendrites. Using selective genetic deletion, we show that netrin-1 expression by excitatory neurons is required for NMDAR-dependent long-term potentiation (LTP) in the adult hippocampus. Furthermore, we demonstrate that application of exogenous netrin-1 is sufficient to trigger the potentiation of excitatory glutamatergic transmission at hippocampal Schaffer collateral synapses via Ca2+-dependent recruitment of GluA1-containing AMPARs, promoting the maturation of immature or nascent synapses. These findings identify a central role for activity-dependent release of netrin-1 as a critical effector of synaptic plasticity in the adult hippocampus. PMID- 30282027 TI - Cell Aggregation Culture Induces Functional Differentiation of Induced Hepatocyte like Cells through Activation of Hippo Signaling. AB - Recent progress in direct lineage reprogramming has enabled the generation of induced hepatocyte-like (iHep) cells and revealed their potential as an alternative to hepatocytes for medical applications. However, the hepatic functions of iHep cells are insufficient compared with those of primary hepatocytes. Here, we show that cell-aggregate formation can rapidly induce growth arrest and hepatic maturation of iHep cells through activation of Hippo signaling. During formation of iHep cell aggregates, Yap inactivation is induced by actin reorganization and intercellular adhesion, leading to upregulation of Hnf1alpha expression in the absence of the Yap/Tead/Chd4 transcriptional repressor unit. Hnf1alpha then acts as a central transcription factor that regulates liver-enriched gene expression in iHep cell aggregates and induces functional differentiation of iHep cells. Moreover, iHep cell aggregates efficiently reconstitute injured liver tissues and support hepatic function after transplantation. Thus, iHep cell aggregates may provide insights into basic research and potential therapies for liver diseases. PMID- 30282028 TI - Blimp-1 Functions as a Molecular Switch to Prevent Inflammatory Activity in Foxp3+RORgammat+ Regulatory T Cells. AB - Foxp3+ regulatory T cells (Treg) are essential modulators of immune responses, but the molecular mechanisms underlying their function are not fully understood. Here we show that the transcription factor Blimp-1 is a crucial regulator of the Foxp3+RORgammat+ Treg subset. The intrinsic expression of Blimp-1 in these cells is required to prevent production of Th17-associated cytokines. Direct binding of Blimp-1 to the Il17 locus in Treg is associated with inhibitory histone modifications but unaltered binding of RORgammat. In the absence of Blimp-1, the Il17 locus is activated, with increased occupancy of the co-activator p300 and abundant binding of the transcriptional regulator IRF4, which is required, along with RORgammat, for IL-17 expression in the absence of Blimp-1. We also show that despite their sustained expression of Foxp3, Blimp-1-/- RORgammat+IL-17-producing Treg lose suppressor function and can promote intestinal inflammation, indicating that repression of Th17-associated cytokines by Blimp-1 is a crucial requirement for RORgammat+ Treg function. PMID- 30282031 TI - Interplay between Ciliary Ultrastructure and IFT-Train Dynamics Revealed by Single-Molecule Super-resolution Imaging. AB - Cilia are built and maintained by intraflagellar transport (IFT), driving IFT trains back and forth along the ciliary axoneme. How IFT brings about the intricate ciliary structure and how this structure affects IFT are not well understood. We identify, using single-molecule super-resolution imaging of IFT components in living C. elegans, ciliary subdomains, enabling correlation of IFT train dynamics to ciliary ultra-structure. In the transition zone, IFT dynamics are impaired, resulting in frequent pauses. At the ciliary base and tip, IFT trains show intriguing turnaround dynamics. Surprisingly, deletion of IFT motor kinesin-II not only affects IFT-train dynamics but also alters ciliary structure. Super-resolution imaging in these mutant animals suggests that the arrangement of IFT trains with respect to the axonemal microtubules is different than in wild type animals. Our results reveal a complex, mutual interplay between ciliary ultrastructure and IFT-train dynamics, highlighting the importance of physical cues in the control of IFT dynamics. PMID- 30282029 TI - Maintenance of Proteostasis by P Body-Mediated Regulation of eIF4E Availability during Aging in Caenorhabditis elegans. AB - Aging is accompanied by a pervasive collapse of proteostasis, while reducing general protein synthesis promotes longevity across taxa. Here, we show that the eIF4E isoform IFE-2 is increasingly sequestered in mRNA processing (P) bodies during aging and upon stress in Caenorhabditis elegans. Loss of the enhancer of mRNA decapping EDC-3 causes further entrapment of IFE-2 in P bodies and lowers protein synthesis rates in somatic tissues. Animals lacking EDC-3 are long lived and stress resistant, congruent with IFE-2-deficient mutants. Notably, neuron specific expression of EDC-3 is sufficient to reverse lifespan extension, while sequestration of IFE-2 in neuronal P bodies counteracts age-related neuronal decline. The effects of mRNA decapping deficiency on stress resistance and longevity are orchestrated by a multimodal stress response involving the transcription factor SKN-1, which mediates lifespan extension upon reduced protein synthesis. Our findings elucidate a mechanism of proteostasis control during aging through P body-mediated regulation of protein synthesis in the soma. PMID- 30282030 TI - XBP1-KLF9 Axis Acts as a Molecular Rheostat to Control the Transition from Adaptive to Cytotoxic Unfolded Protein Response. AB - Transcription factor XBP1s, activated by endoplasmic reticulum (ER) stress in a dose-dependent manner, plays a central role in adaptive unfolded protein response (UPR) via direct activation of multiple genes controlling protein refolding. Here, we report that elevation of ER stress above a critical threshold causes accumulation of XBP1s protein sufficient for binding to the promoter and activation of a gene encoding a transcription factor KLF9. In comparison to other XBP1s targets, KLF9 promoter contains an evolutionary conserved lower-affinity binding site that requires higher amounts of XBP1s for activation. In turn, KLF9 induces expression of two regulators of ER calcium storage, TMEM38B and ITPR1, facilitating additional calcium release from ER, exacerbation of ER stress, and cell death. Accordingly, Klf9 deficiency attenuates tunicamycin-induced ER stress in mouse liver. These data reveal a role for XBP1s in cytotoxic UPR and provide insights into mechanisms of life-or-death decisions in cells under ER stress. PMID- 30282032 TI - Endogenous rRNA Sequence Variation Can Regulate Stress Response Gene Expression and Phenotype. AB - Prevailing dogma holds that ribosomes are uniform in composition and function. Here, we show that nutrient limitation-induced stress in E. coli changes the relative expression of rDNA operons to alter the rRNA composition within the actively translating ribosome pool. The most upregulated operon encodes the unique 16S rRNA, rrsH, distinguished by conserved sequence variation within the small ribosomal subunit. rrsH-bearing ribosomes affect the expression of functionally coherent gene sets and alter the levels of the RpoS sigma factor, the master regulator of the general stress response. These impacts are associated with phenotypic changes in antibiotic sensitivity, biofilm formation, and cell motility and are regulated by stress response proteins, RelA and RelE, as well as the metabolic enzyme and virulence-associated protein, AdhE. These findings establish that endogenously encoded, naturally occurring rRNA sequence variation can modulate ribosome function, central aspects of gene expression regulation, and cellular physiology. PMID- 30282033 TI - Evolutionary Capacitance Emerges Spontaneously during Adaptation to Environmental Changes. AB - All biological populations are to a greater or lesser degree evolvable, but the forces that shape evolvability, especially the evolution of evolvability as an adaptive response to pressure to evolve rapidly, are a source of controversy. One determinant of evolvability is the set of possible mutations available to a genotype, or "mutational neighborhood." A benign (instead of deleterious) mutational neighborhood can enhance evolvability. Whether selection for evolvability itself can result in a more benign mutational neighborhood remains an open question. We document the evolution of increased evolvability in a fluctuating environment despite using a regime that precludes, by design, the adaptive evolution of evolvability. Instead, a benign mutational neighborhood arises as a byproduct of transiently elevated error rates via a mechanism that we call emergent evolutionary capacitance. This is evolutionary capacitance similar to that seen in a model system for capacitance, the yeast prion [PSI+], but without a capacitor. PMID- 30282036 TI - Smed-myb-1 Specifies Early Temporal Identity during Planarian Epidermal Differentiation. AB - The planarian epidermis provides an excellent model to explore adult stem cell (ASC) lineage development due to well-characterized and distinct spatiotemporal phases during lineage progression. Using flow cytometry-isolated cells enriched in epidermal progenitors, we performed transcriptional profiling and RNAi screening to uncover regulators of epidermal differentiation. We identified a MYB type transcription factor (Smed-myb-1) required for the specification of the first temporal phase of post-mitotic maturation. Knockdown of myb-1 abolished the early progenitor phase of differentiation without ceasing production of subsequent epidermal progenitor states or homeostatic turnover and regeneration of the epidermis. Further examination revealed accelerated maturation of ASC descendants, with premature entry into subsequent progeny phases and, ultimately, the epidermis. These results demonstrate that a spatiotemporal shift in lineage progression occurs in the absence of the early progenitor state after myb-1 RNAi, and identify myb-1 as a critical regulator of the early temporal window in stepwise specification during planarian epidermal differentiation. PMID- 30282035 TI - DET1 and COP1 Modulate the Coordination of Growth and Immunity in Response to Key Seasonal Signals in Arabidopsis. AB - Plant growth and development and outcomes of plant-microbe interactions are defined by coordinated responses to seasonal signals. The mechanisms that control the coordinated regulation of growth and immunity are not well understood. Here, we show that a common signaling module integrates environmental signals, such as photoperiod and temperature, to regulate the growth-defense balance. Key light signaling components De-Etiolated 1 (DET1) and Constitutive Photomorphogenic 1 (COP1) negatively regulate immunity and are essential for immune modulation by photoperiod and temperature. Our results show that this is regulated by the transcription factor Phytochrome Interacting Factor 4 (PIF4), suggesting that the DET1/COP1-PIF4 module acts as a central hub for the control of growth and immunity in response to seasonal signals. These findings provide a regulatory framework for environmental signal integration. PMID- 30282034 TI - Elongation/Termination Factor Exchange Mediated by PP1 Phosphatase Orchestrates Transcription Termination. AB - Termination of RNA polymerase II (Pol II) transcription is a key step that is important for 3' end formation of functional mRNA, mRNA release, and Pol II recycling. Even so, the underlying termination mechanism is not yet understood. Here, we demonstrate that the conserved and essential termination factor Seb1 is found on Pol II near the end of the RNA exit channel and the Rpb4/7 stalk. Furthermore, the Seb1 interaction surface with Pol II largely overlaps with that of the elongation factor Spt5. Notably, Seb1 co-transcriptional recruitment is dependent on Spt5 dephosphorylation by the conserved PP1 phosphatase Dis2, which also dephosphorylates threonine 4 within the Pol II heptad repeated C-terminal domain. We propose that Dis2 orchestrates the transition from elongation to termination phase during the transcription cycle by mediating elongation to termination factor exchange and dephosphorylation of Pol II C-terminal domain.

Malignant breast tumors have lower Lactobacillus abundance compared with benign lesions, implicating Lactobacillus as a negative regulator of breast cancer. Diet is a main determinant of gut microbial diversity. Whether diet affects breast microbiome populations is unknown. In a non-human primate model, we found that consumption of a Western or Mediterranean diet modulated mammary gland microbiota and metabolite profiles. Mediterranean diet consumption led to increased mammary gland Lactobacillus abundance compared with Western diet-fed monkeys. Moreover, mammary glands from Mediterranean diet-fed monkeys had higher levels of bile acid metabolites and increased bacterial-processed bioactive compounds. These data suggest that diet directly influences microbiome populations outside the intestinal tract in distal sites such as the mammary gland. Our study demonstrates that diet affects the mammary gland microbiome, establishing an alternative mechanistic pathway for breast cancer prevention. PMID- 30282039 TI - CD8+ T Cell Activation Leads to Constitutive Formation of Liver Tissue-Resident Memory T Cells that Seed a Large and Flexible Niche in the Liver. AB - Liver tissue-resident memory T (Trm) cells migrate throughout the sinusoids and are capable of protecting against malaria sporozoite challenge. To gain an understanding of liver Trm cell development, we examined various conditions for their formation. Although liver Trm cells were found in naive mice, their presence was dictated by antigen specificity and required IL-15. Liver Trm cells also formed after adoptive transfer of in vitro-activated but not naive CD8+ T cells, indicating that activation was essential but that antigen presentation within the liver was not obligatory. These Trm cells patrolled the liver sinusoids with a half-life of 36 days and occupied a large niche that could be added to sequentially without effect on subsequent Trm cell cohorts. Together, our findings indicate that liver Trm cells form as a normal consequence of CD8+ T cell activation during essentially any infection but that inflammatory and antigenic signals preferentially tailor their development. PMID- 30282041 TI - IFIT1 Exerts Opposing Regulatory Effects on the Inflammatory and Interferon Gene Programs in LPS-Activated Human Macrophages. AB - Activation of the TLR4 signaling pathway by lipopolysaccharide (LPS) leads to induction of both inflammatory and interferon-stimulated genes, but the mechanisms through which these coordinately activated transcriptional programs are balanced to promote an optimal innate immune response remain poorly understood. In a genome-wide small interfering RNA (siRNA) screen of the LPS induced tumor necrosis factor alpha (TNF-alpha) response in macrophages, we identify the interferon-stimulated protein IFIT1 as a negative regulator of the inflammatory gene program. Transcriptional profiling further identifies a positive regulatory role for IFIT1 in type I interferon expression, implicating IFIT1 as a reciprocal modulator of LPS-induced gene classes. We demonstrate that these effects of IFIT1 are mediated through modulation of a Sin3A-HDAC2 transcriptional regulatory complex at LPS-induced gene loci. Beyond the well studied role of cytosolic IFIT1 in restricting viral replication, our data demonstrate a function for nuclear IFIT1 in differential transcriptional regulation of separate branches of the LPS-induced gene program. PMID- 30282038 TI - Two Faces of CwlM, an Essential PknB Substrate, in Mycobacterium tuberculosis. AB - Tuberculosis claims >1 million lives annually, and its causative agent Mycobacterium tuberculosis is a highly successful pathogen. Protein kinase B (PknB) is reported to be critical for mycobacterial growth. Here, we demonstrate that PknB-depleted M. tuberculosis can replicate normally and can synthesize peptidoglycan in an osmoprotective medium. Comparative phosphoproteomics of PknB producing and PknB-depleted mycobacteria identify CwlM, an essential regulator of peptidoglycan synthesis, as a major PknB substrate. Our complementation studies of a cwlM mutant of M. tuberculosis support CwlM phosphorylation as a likely molecular basis for PknB being essential for mycobacterial growth. We demonstrate that growing mycobacteria produce two forms of CwlM: a non-phosphorylated membrane-associated form and a PknB-phosphorylated cytoplasmic form. Furthermore, we show that the partner proteins for the phosphorylated and non-phosphorylated forms of CwlM are FhaA, a fork head-associated domain protein, and MurJ, a proposed lipid II flippase, respectively. From our results, we propose a model in which CwlM potentially regulates both the biosynthesis of peptidoglycan precursors and their transport across the cytoplasmic membrane. PMID- 30282040 TI - The Kinase Activity of Hematopoietic Progenitor Kinase 1 Is Essential for the Regulation of T Cell Function. AB - We examined hematopoietic protein kinase 1 (HPK1), whose reliance on scaffold versus kinase functions for negative immune cell regulation is poorly understood and critical to its assessment as a viable drug target. We identify kinase dependent roles for HPK1 in CD8 T cells that restrict their anti-viral and anti tumor responses by using HPK1 kinase-dead (HPK1.kd) knockin mice. Loss of HPK1 kinase function enhanced T cell receptor signaling and cytokine secretion in a T cell-intrinsic manner. In response to chronic lymphocytic choriomeningitis virus (LCMV) infection or tumor challenge, viral clearance and tumor growth inhibition were enhanced in HPK1.kd mice, accompanied by an increase in effector CD8 T cell function. Co-blockade of PD-L1 further enhanced T effector cell function, resulting in superior anti-viral and anti-tumor immunity over single target blockade. These results identify the importance of HPK1 kinase activity in the negative regulation of CD8 effector functions, implicating its potential as a cancer immunotherapy target.

AB - Pro-opiomelanocortin (POMC)-expressing neurons regulate energy balance and mediate the effects of some classes of anti-obesity therapeutics. In this issue of Cell Metabolism, D'Agostino et al. (2018) demonstrate that a small and often overlooked population of POMC neurons in the brainstem contributes to satiation induced by the FDA-approved drug lorcaserin. PMID- 30282042 TI - Removal of hERG potassium channel affinity through introduction of an oxygen atom: Molecular insights from structure-activity relationships of strychnine and its analogs. AB - Nux vomica has been effectively used in Traditional Chinese Medicine. The processing of Nux vomica is necessary to reduce toxicity before it can be used in clinical practice. However, the mechanism for processing detoxification is unclear. hERG channels have been subjected to a routine test for compound cardiac toxicity in the drug development process. Therefore, we examined the effects and mechanisms of strychnine and brucine, two main ingredients of Nux vomica, and their N-oxides on hERG channels. Strychnine and brucine exhibited concentration dependent inhibition of hERG channels with IC50 values of 25.9 MUM and 44.18 MUM, respectively. However, their nitrogen oxidative derivatives produced by processing of Nux vomica, strychnine N-oxide and brucine N-oxide, lost their activity on hERG channels. Compared to their parent compounds, only an oxygen atom was introduced in the nitrogen oxidative isoforms to compensate for the N+ - charge, suggesting that the protonated nitrogen is the key group for strychnine and brucine binding to hERG channel. Alanine-mutagenesis identified Y652 is the most important residue for strychnine and brucine binding to hERG channel. Y652A mutation increased the IC50 for strychnine and brucine by 21.64-fold and 29.78 fold that of WT IhERG, respectively. Docking simulations suggested that the protonated nitrogen of strychnine and brucine formed a cation-pi interaction with the aromatic ring of Y652. This study suggests that introduction of an oxygen to compensate for the N+ - charge could be a useful strategy for reducing hERG potency and increasing the safety margin of alkaloid-type compounds in drug development. PMID- 30282044 TI - AMPK Regulates the Epigenome through Phosphorylation of TET2. AB - Emerging evidence suggests that changes to cellular metabolism can regulate epigenetic modifications to alter gene expression. Recently in Nature, Wu et al. show that the metabolic regulator AMPK can phosphorylate and thus stabilize the epigenetic modifying enzyme TET2, defining a novel signaling link between metabolism and the epigenome. PMID- 30282045 TI - Shipping Calpastatin to the Rescue: Prevention of Neuromuscular Degeneration through Mitofusin 2. AB - How neuromuscular junctions (NMJs) are lost in disease and aging is unclear. Recently in Cell Metabolism, Wang et al. (2018) discovered that endoplasmic reticulum-mitochondria tethering by Mitofusin 2 is required to organize a cleft between these two organelles, which, like a lorry, traffics down the axon to distribute calpastatin to terminals where it blocks NMJ degradation. PMID- 30282046 TI - Fatty Acid Oxidation in Macrophages and T Cells: Time for Reassessment? AB - Previous immunometabolism research using the CPT1 inhibitor etomoxir suggests that long-chain fatty acid oxidation (LC-FAO) supports IL-4-driven alternative macrophage activation (M(IL-4)) and regulates memory and regulatory T cell formation. Divakaruni et al. (2018) and Raud et al. (2018) now report that LC-FAO is largely dispensable for these processes.

PMID- 30282048 TI - The ocular surface in children: A review of current knowledge and meta-analysis of tear film stability and tear secretion in children. AB - PURPOSE: A review of ocular surface and meta-analysis of tear stability (tear break up time, TBUT) and tear secretion (Schirmer test) values in healthy children was conducted. METHODS: Articles published between 1996 and 2017 indexed on MEDLINE, PubMed, Embase, Scopus and Google scholar were retrieved using defined search terms. Statistical analysis (including sensitivity analysis and meta regression) was performed. RESULTS: 23 studies were summarised (5291 neonates (0-29 days), infants (1 month-1 year) or children (1-18 years)) and a meta-analysis conducted using 15 eligible studies (1077 participants). The combined mean TBUT in children was 14.64 s (s) (95% CI, 11.64, 17.64) and 21.76 s (95% CI, 20.43, 23.09) for sodium fluorescein TBUT and non-invasive TBUT respectively (NIBUT). The combined mean NIBUT was 32.5 s (95% CI, 31.78-33.22) in neonates. The combined mean Schirmer I with and without anesthesia were 16.26 mm/5 min (95% CI, 13.17, 19.36) and 29.30 mm/5 min (95% CI, 27.65, 30.96) in children and 9.36 mm/5 min (95% CI, 6.54, 12.18) and 17.63 mm/5 min (95% CI, 12.03, 23.23) in neonates. Meta regression showed a significantly lower TBUT in children from studies conducted in Asia (p = 0.004). CONCLUSION: There is paucity of data on ocular surface variables in healthy children, making it difficult to draw valid comparisons with adult values. PMID- 30282049 TI - Vibration spectroscopy and body biofluids: Literature review for clinical applications. AB - Vibrational spectroscopy techniques such as Raman and IR (infrared) allow real time, non-invasive and non-destructive analysis of organic compounds with a good limit-of-detection. This review aims to show the progress of clinical diagnosis and prognosis due to advances of vibrational spectroscopy techniques in biofluids through an extensive literature review. This review was performed by searching for studies using the keywords "biofluids or biological fluids" and "diagnostic techniques" in PubMed, Scopus and Google Scholar. We found 580 articles in the 1990s, 1171 articles in the 2000s and 1688 in the years from 2011. Also, a second search including "biofluids or biological fluids" and "vibrational spectroscopy" returned only one article in the 1990s, three papers in the 2000s and 18 in the years from 2011.This growth suggests a great potential of biofluid research using vibrational spectroscopy. Sample collection variations(quantity and contaminations due to contact with other body parts and their secretions) are important factors that influence sample composition. Once these factors are taken into account, spectroscopic analysis may provide the necessary information to identify a disease, lesion, tumor or infection. With the present review we aim to encourage the study of vibrational spectroscopy techniques for analysis of biofluids focusing in clinical applications. In the future, it will widely benefit clinicians, allowing new diagnostic approaches, and for patients to have early diagnosis for most every disease. PMID- 30282050 TI - Proteomic changes in Arthrobotrys oligospora conidia in response to benzaldehyde induced fungistatic stress. AB - Soil fungistasis limits the effect of fungal agents designed to control plant parasitic nematodes. Benzaldehyde is a fungistatic factor produced by soil microorganisms that can suppress conidial germination, but the molecular mechanism of this suppression is unknown. In this study, three conidial proteomes of Arthrobotrys oligospora ATCC24927, a nematode-trapping fungus, were obtained, quantified, and compared. Under benzaldehyde fungistatic stress, conidial protein expression profile changed significantly. Screening with a twofold selection criterion revealed 164 up-regulated and 110 down-regulated proteins. 17 proteins related to protein translation were down-regulated and gene transcription analysis suggested that the repression of proteins translation might be one mechanism by which benzaldehyde inhibites conidial germination. Benzaldehyde also resulted in the down-regulation of respiratory chain proteins and mitochondrial processes, as well as the repression of conidial DNA synthesis. In addition, the conidia up-regulated several proteins that enable it to resist benzaldehyde induced fungistatis, and this was confirmed by a functional assessment of two knockout mutants. This study reveals putative mechanisms by which benzaldehyde causes fungistasis as well as the proteomic response of conidia to benzaldehyde. SIGNIFICANCE: Soil fungistasis limits the effect of fungal agents designed to control plant-parasitic nematodes. Benzaldehyde is one of fungistatic factors produced by soil microorganisms that can suppress conidial germination. In this study, we found that conidial protein expression profile changed significantly under benzaldehyde fungistatic stress. This research revealed new mechanistic data that describe how benzaldehyde is responsible for fungiststis by inhibiting conidial germination. Moreover, we also found that conidia can resist benzaldehyde by up-regulating proteins such as benzaldehyde dehydrogenase and heat shock proteins. This study also showed that proteomics methods play important roles in addressing soil fungistatic mechanisms.

AB - We report a 34-year-old male patient with a novel variant in KMT2D gene, which finally ended a quest for a diagnosis that was clinically suspected in the past, prior the molecular basis of Kabuki Syndrome (KS) was known. The patient showcases the multisystemic features, with involvement of all previously associated with KS body systems, presence of immune deficiency as well as autoimmune disorders, requiring three pancreatic transplants. We also report, for the first time to our knowledge, the presence of epidural lipomatosis and Hodgkin Lymphoma in a patient with KS. PMID- 30282052 TI - Micro-patterned endogenous stroma equivalent induces polarized crypt-villus architecture of human small intestinal epithelium. AB - The small intestine is the major site for digestion, drug and nutrient absorption, as well as a primary site for many diseases. Current in vitro gut models fail in reproducing the complex intestinal extracellular matrix (ECM) network of the lamina propria and the peculiar architecture of the crypt-villus axis. Here we proposed a novel in vitro human intestine model that mimics the intestinal stromal topography and composition and strictly reproduces the tissue polarity with the crypt-villus architecture. First we developed a 3D human intestinal stromal equivalent (3D-ISE) composed of human intestinal subepithelial myofibroblasts (ISEMFs) embedded in their own extracellular matrix. Then, we seeded human colon carcinoma-derived cells (Caco-2) onto flat or patterned cell synthetized stromal equivalent structure and cultured them until the formation of a well-oriented epithelium. We demonstrated that the patterned stroma increases the absorbing surface area, the epithelial proliferation rate, and the density of microvilli. In addition it induces changes in the biological functions of the epithelial cells such as enzymes and mucus production, polarization and tightness showing a physiological cell-lineage compartmentalization along the crypt/villi axes with the undifferentiated phenotypes at the base. At last, we reproduced an inflamed intestinal tissue model in which we identified the contribution of the stromal microenvironment by molecular (cytokines release and MMPs production) and immunofluorescence analyses and the effects of the epithelial-stromal cross-talk in the intestinal innate immunity by multiphoton investigation that revealed differences in the collagen network architecture. STATEMENT OF SIGNIFICANCE: The intestinal stroma morphology and composition has a fundamental role in crypt villus development and appropriate epithelial cell-lineage compartmentalization. On this base, here we develop an engineered organotypic model of human intestine equivalent in which a functional epithelial/ECM crosstalk is recapitulated. Due to its accessible luminal surface it provides a new platform for preclinical studies of mucosal immunology and bowel inflammation as well as the assessment of pharmaco-toxicity studies. PMID- 30282053 TI - Control of mRNA splicing by noncoding intragenic RNA elements that evoke a cellular stress response. AB - Once activated by double-helical RNA, mammalian RNA-dependent stress protein kinase, PKR, phosphorylates its substrate, translation initiation factor eIF2alpha, to inhibit translation. eIF2alpha phosphorylation is critical for mounting a cellular stress response. We describe short, 100-200 nucleotide elements within cellular genes that, once transcribed, form RNA structures that potently activate PKR in the vicinity of the RNA and thereby tightly regulate gene expression in cis. Intragenic RNA activators of PKR can (a) attenuate translation of the encoded mRNA by activating PKR and inducing eIF2alpha phosphorylation, exemplified by the IFN-gamma gene, or (b) greatly enhance mRNA splicing efficiency by activating PKR and inducing nuclear eIF2alpha phosphorylation, thus enabling efficient early spliceosome assembly, exemplified by the adult and fetal globin genes and the TNF-alpha gene that activates PKR through an RNA pseudoknot conserved from fish to humans. These opposite outcomes considerably extend the potential scope of gene regulation by these novel RNA elements.

AB - Diabetic kidney disease (DKD), defined as reduced glomerular filtration rate (GFR), elevated urine albumin excretion, or both that is clinically attributable to diabetes, is a common and morbid diabetes complication. Animal-experimental data, observational human studies, and short-term clinical trials suggest that vitamin D and omega-3 fatty acid supplements may be safe and inexpensive interventions to reduce the incidence and progression of DKD. The Vitamin D and Omega-3 Trial to Prevent and Treat DKD (VITAL-DKD) was designed as an ancillary study to the VITAL trial of 25,871 US adults. In a 2 * 2 factorial design, VITAL participants were randomly assigned to vitamin D3 (cholecalciferol, 2000 IU daily) or placebo and to marine omega-3 fatty acids (eicospentaenoic acid and docosahexaenoic acid, 1 g/d) or placebo. VITAL-DKD enrolled a subset of 1326 VITAL participants with type 2 diabetes at baseline to test the effects of vitamin D and omega-3 fatty acids on changes in estimated GFR and urine albumin excretion. Over five years of follow-up, VITAL-DKD collected blood and urine samples to quantify changes in estimated GFR (the primary study outcome) and urine albumin excretion. At baseline, mean age of VITAL-DKD participants was 67.6 years, 46% were women, 30% were of racial or ethnic minority, and the prevalence of DKD (estimated GFR <60 mL/min/1.73m2 or urine albumin-creatinine ratio >= 30 mg/g) was 17%. In this type 2 diabetes population, VITAL-DKD will test the hypotheses that vitamin D and omega-3 fatty acids help prevent the development and progression of DKD. PMID- 30282057 TI - Alendronate improves bone density and type I collagen accumulation but increases the amount of pentosidine in the healing dental alveolus of ovariectomized rabbits. AB - BACKGROUND: It has been shown that the oral aminobisphosphonate sodium alendronate (ALN) therapy reduces the risk of main fractures in osteoporotic women, but its effect on the jaw bones is poorly known. Here, we hypothesized that ALN affects the newly formed alveolar bone, particularly the quality of the type I collagen cross-linking. METHODS: Osteoporosis was induced by ovariectomy (OVX) in 6-month old rabbits. Six weeks following surgery, eight animals were treated by oral gavage with ALN (OVX + ALN) and ten received placebo (OVX + Pbo). Another six rabbits which were sham operated also received placebo (SHAM + Pbo). One month following the beginning of treatment, the upper and lower left first premolars were removed. Six weeks later, the upper and the lower right first premolars were also extracted. One month after the second extraction, biopsies were collected from the maxillary extraction sites and collagen crosslinks were analyzed in the newly formed bone tissue by HPLC. Also, at this time, mandibular bone segments were subjected to MUCT. RESULTS: Animals treated with ALN achieved a roughly 2-time greater bone volume fraction value at a late healing period than animals in the other groups (p < 0.05). Collagen mean results were 2- to 4-times superior in the OVX + ALN group than in the control groups (p < 0.05). ALN treated animals presented higher amounts of the non-enzymatic collagen cross-link pentosidine (PEN) than the sham-operated rabbits (p < 0.05), whereas the OVX + Pbo group presented the highest amount of PEN (p < 0.05). CONCLUSION: Alendronate increases bone volume and collagen accumulation, but does not fully rescue the non-osteoporotic alveolar tissue quality as is evident from the increased quantity of pentosidine. PMID- 30282056 TI - Community Study of Outcome Monitoring for Emotional Disorders in Teens (COMET): A comparative effectiveness trial of a transdiagnostic treatment and a measurement feedback system. AB - Emotional disorders, encompassing a range of anxiety and depressive disorders, are the most prevalent and comorbid psychiatric disorders in adolescence. Unfortunately, evidence-based psychosocial therapies typically focus on single disorders, are rarely adopted by community mental health center clinicians, and effect sizes are modest. This article describes the protocol for a comparative effectiveness study of two novel interventions designed to address these challenges. The first intervention is a transdiagnostic treatment (the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Adolescents, UP A), a promising new approach that uses a small number of common strategies to treat a broad range of emotional disorders, and their underlying shared emotional vulnerabilities. The second intervention is a standardized measurement feedback system, the Youth Outcomes Questionnaire (YOQ), designed to improve clinical decision making using weekly symptom and relational data. The three study arms are treatment as usual (TAU), TAU plus the YOQ (TAU+), and UP-A (used in combination with the YOQ). The primary aims of the study are to [1] compare the effects of the UP-A and TAU+ to TAU in community mental health clinics, [2] to isolate the effects of measurement and feedback by comparing the UP-A and TAU+ condition, and [3] to examine the mechanisms of action of both interventions. Design considerations and study methods are provided to inform future effectiveness research. PMID- 30282058 TI - Understanding the severity of depression: Which symptoms of depression are the best indicators of depression severity? AB - BACKGROUND: In DSM-5, all symptoms of depression are considered equal representations of severity. In ICD-10, the type of symptom is considered in classifying severity. It is important to better understand if the defining symptoms of depression are differentially associated with overall severity so that severity categorization in diagnostic systems is most valid. In the present study from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project we examined the association between the individual diagnostic criteria for major depressive disorder (MDD) and global ratings of depression severity. We thus examined whether there is support for the ICD-10 approach in which some symptoms are better indicators of severity than are other symptoms. METHODS: Patients were evaluated with a semi-structured interview and the presence of each symptom of MDD was recorded. Patients were also rated on the Clinical Global Index of severity (CGI-S). RESULTS: All 9 DSM-5 criteria were significantly correlated with the CGI with suicidality having the highest correlation. A regression analysis found that all 9 criteria were significant predictors of the CGI. At the symptom level, 15 of the 17 symptoms were significantly correlated with the CGI (all except increased appetite and increased weight). DISCUSSION: There were differences between the symptoms of depression in their association with severity with suicidal ideation, depressed mood, and anhedonia having the highest correlations with severity whereas some symptoms were not significantly associated with severity distinctions. Future descriptions of the severity of depression should not consider all criteria as equal representations of severity. PMID- 30282059 TI - Contribution of stress and coping strategies to problematic Internet use in patients with schizophrenia spectrum disorders. AB - INTRODUCTION: Internet use is already high and increasing rapidly among people with psychotic disorders, but there have been few studies on problematic Internet use (PIU) among patients with schizophrenia spectrum disorders. This study aimed to measure the prevalence of PIU and identify the factors associated with PIU among patients with schizophrenia spectrum disorders. METHODS: A cross-sectional survey was performed that included 368 outpatients with schizophrenia spectrum disorders: 317 with schizophrenia, 22 with schizoaffective disorder, 9 with schizophreniform disorder, and 20 with other schizophrenia spectrum and psychotic disorders. The severity of psychotic symptoms and levels of personal and social functioning were assessed by the Clinician-rated Dimensions of Psychosis Symptom Severity (CRDPSS) scale and the Personal and Social Performance (PSP) scale, respectively. PIU was evaluated using Young's Internet Addiction Test (IAT). Additionally, the Hospital Anxiety and Depression Scale (HADS), Perceived Stress Scale (PSS), Rosenberg Selfesteem Scale (RSES), and Brief Coping Orientation to Problems Experienced (COPE) Inventory were administered. RESULTS: PIU was identified in 81 (22.0%) of the 368 patients with schizophrenia spectrum disorders. Subjects with PIU were significantly younger and more likely to be male. Scores on the HADS, PSS, and dysfunctional coping dimension of the Brief COPE Inventory were significantly higher, and RSES scores were significantly lower, in the PIU group. Logistic regression analysis indicated that PIU in patients was significantly associated with scores on the PSS and dysfunctional coping dimension of the Brief COPE Inventory. CONCLUSIONS: Patients with schizophrenia spectrum disorders and PIU were significantly more likely to have high levels of perceived stress and dysfunctional coping strategies. Patients with schizophrenia spectrum disorders who also engage in PIU may benefit from interventions that help them to develop appropriate skills for coping with stress. PMID- 30282060 TI - A correlative approach, combining chlorophyll a fluorescence, reflectance, and Raman spectroscopy, for monitoring hydration induced changes in Antarctic lichen Dermatocarpon polyphyllizum. AB - Lichens are successful colonizers in extreme environments worldwide, and they are considered to have played an important role during the evolution of life. Here, we have used a correlative approach, combining three optical signals (chlorophyll a fluorescence (ChlF), reflectance, and Raman spectra), to monitor hydration induced changes in photosynthetic properties of an Antarctic chlorolichen Dermatocarpon polyphyllizum. We measured these three signals from this lichen at different stages (after 4 h, 24 h, and 48 h) of hydration, and compared the data obtained from this lichen in "dry state" as well as in different "hydrated state". We found that dry state of this lichen has: (1) no variable ChlF, (2) high reflectance, with no red-edge and almost zero photochemical reflectance index (PRI), and (3) low-intensity Raman bands of their carotenoids. Furthermore, 4 h of hydration, increased its relative water content (RWC) by 93%, showed red edge in reflectance spectra, and changed the maximum quantum yield of PSII photochemistry (Fv/Fm) from 0 to 0.57 +/- 0.01. We found that reflectance indices, normalized difference index (NDVI) and PRI, significantly differed between brown and black/green surface areas, at all hydration stages; whereas, a shift in the Raman nu1(CC) band, between brown and black/green surface areas, occurred in 24 h or 48 h hydrated samples. These data indicate that hydration shortly (within 4 h) activated functions of photosynthetic apparatus, and the de novo synthesis of carotenoids occured in 24 h or 48 h. Furthermore, exposure to high irradiance (2000 MUmol photons m-2 s-1), in 48 h hydrated lichen, significantly reduced Fv/Fm (signifies photoinhibition) and increased PRI (represents changes in xanthophyll pigments). We conclude that the implication of such a correlative approach is highly useful for understanding survival and protective mechanisms on extremophile photosynthetic organisms. PMID- 30282061 TI - Joint registration and synthesis using a probabilistic model for alignment of MRI and histological sections. AB - Nonlinear registration of 2D histological sections with corresponding slices of MRI data is a critical step of 3D histology reconstruction algorithms. This registration is difficult due to the large differences in image contrast and resolution, as well as the complex nonrigid deformations and artefacts produced when sectioning the sample and mounting it on the glass slide. It has been shown in brain MRI registration that better spatial alignment across modalities can be obtained by synthesising one modality from the other and then using intra modality registration metrics, rather than by using information theory based metrics to solve the problem directly. However, such an approach typically requires a database of aligned images from the two modalities, which is very difficult to obtain for histology and MRI. Here, we overcome this limitation with a probabilistic method that simultaneously solves for deformable registration and synthesis directly on the target images, without requiring any training data. The method is based on a probabilistic model in which the MRI slice is assumed to be a contrast-warped, spatially deformed version of the histological section. We use approximate Bayesian inference to iteratively refine the probabilistic estimate of the synthesis and the registration, while accounting for each other's uncertainty. Moreover, manually placed landmarks can be seamlessly integrated in the framework for increased performance and robustness. Experiments on a synthetic dataset of MRI slices show that, compared with mutual information based registration, the proposed method makes it possible to use a much more flexible deformation model in the registration to improve its accuracy, without compromising robustness. Moreover, our framework also exploits information in manually placed landmarks more efficiently than mutual information: landmarks constrain the deformation field in both methods, but in our algorithm, it also has a positive effect on the synthesis - which further improves the registration. We also show results on two real, publicly available datasets: the Allen and BigBrain atlases. In both of them, the proposed method provides a clear improvement over mutual information based registration, both qualitatively (visual inspection) and quantitatively (registration error measured with pairs of manually annotated landmarks). PMID- 30282062 TI - Prospects of annular differential phase contrast applied for optical sectioning in STEM. AB - The annular differential phase contrast (ADPC) mode in a third-order spherical aberration-corrected scanning transmission electron microscope (STEM) has recently been realized at an operating voltage of 300 kV by inserting a physical Fresnel phase plate in front of the objective lens and by using a detector geometry which matches that of the Fresnel phase plate [1]. By image calculation we explore the feasibility of this mode for the voltage range of 20-80kV. Alternatively, we mimic the Fresnel phase plate material-free with the help of the adjustable aberrations of the corrector. The additional correction of chromatic aberration, fifth-order spherical aberration and image spread improves significantly the resolution and contrast. Under these advanced conditions it is possible to achieve optical sectioning in the ADPC mode with atomic resolution and a depth of field shorter than 3 A for an accelerating voltage of 30 kV. Moreover, we show that the contrast obtained in the ADPC mode is clearly superior over the contrast in incoherent bright-field (IBF) and high-angle annular dark field (HAADF), the two other common methods in STEM. We propose that with the advanced ADPC method applied in STEM, the investigation of the inner structure of thick samples will be possible without slicing. PMID- 30282064 TI - Phenotypic variations in carriers of predicted protein-truncating genetic variants in MYBPC3: an autopsy-based case series. AB - Our aim is to characterize predicted protein-truncating variants (PTVs) in MYBPC3, the gene most commonly associated with hypertrophic cardiomyopathy (HCM), found in a series of autopsied HCM cases after sudden unexpected cardiac death. All cases underwent death scene investigation, gross and microscopic autopsies, toxicological testing, a review of medical records, and a molecular analysis of 95 cardiac genes. We found four pathogenic PTVs in MYBPC3 among male decedents. All variants were previously submitted to ClinVar without phenotype details. Two PTVs were located in the cardiac-specific myosin S2-binding (M) motif at the N terminus of the MYBPC3-encoded cMyBP-C protein, and two PTVs were in the non cardiac-specific C-terminus of the protein. The carriers of two cardiac-specific M-motif PTVs died at age 38 years; their heart weight (HW, g) and body mass index (BMI, kg/m2) ratio were 34.90 (890/25.5) and 23.56 (980/41.6), respectively. In contrast, the carriers of two non-cardiac-specific C-terminal PTVs died at age 57 and 67 years, respectively; their HW and BMI ratio were 14.71 (450/30.6) and 13.98 (600/42.9), respectively. A detailed three-generation family study was conducted in one case. This study showed age-at-death variations among MYBPC3 PTVs carriers in adult males. PMID- 30282063 TI - Accuracy of different three-dimensional subcortical human brain atlases for DBS lead localisation. AB - BACKGROUND: Accurate interindividual comparability of deep brain stimulation (DBS) lead locations in relation to the surrounding anatomical structures is of eminent importance to define and understand effective stimulation areas. The objective of the current work is to compare the accuracy of the DBS lead localisation relative to the STN in native space with four recently developed three-dimensional subcortical brain atlases in the MNI template space. Accuracy is reviewed by anatomical and volumetric analysis as well as intraoperative electrophysiological data. METHODS: Postoperative lead localisations of 10 patients (19 hemispheres) were analysed in each individual patient based on Brainlab software (native space) and after normalization into the MNI space and application of 4 different human brain atlases using Lead-DBS toolbox within Matlab (template space). Each patient's STN was manually segmented and the relation between the reconstructed lead and the STN was compared to the 4 atlas based STN models by applying the Dice coefficient. The length of intraoperative electrophysiological STN activity along different microelectrode recording tracks was measured and compared to reconstructions in native and template space. Descriptive non-parametric statistical tests were used to calculate differences between the 4 different atlases. RESULTS: The mean STN volume of the study cohort was 153.3 +/- 40.3 mm3 (n = 19). This is similar to the STN volume of the DISTAL atlas (166 mm3; p = .22), but significantly larger compared to the other atlases tested in this study. The anatomical overlap of the lead-STN-reconstruction was highest for the DISTAL atlas (0.56 +/- 0.18) and lowest for the PD25 atlas (0.34 +/- 0.17). A total number of 47 MER trajectories through the STN were analysed. There was a statistically significant discrepancy of the electrophysiogical STN activity compared to the reconstructed STN of all four atlases (p < .0001). CONCLUSION: Lead reconstruction after normalization into the MNI template space and application of four different atlases led to different results in terms of the DBS lead position relative to the STN. Based on electrophysiological and imaging data, the DISTAL atlas led to the most accurate display of the reconstructed DBS lead relative to the DISTAL-based STN. PMID- 30282065 TI - How Long Non-Coding RNAs and MicroRNAs Mediate the Endogenous RNA Network of Head and Neck Squamous Cell Carcinoma: a Comprehensive Analysis. AB - BACKGROUND/AIMS: Long non-coding RNAs (lncRNAs) act as competing endogenous RNAs (ceRNAs) to compete for microRNAs (miRNAs) in cancer metastasis. Head and neck squamous cell carcinoma (HNSCC) is one of the most common human cancers and rare biomarkers could predict the clinical prognosis of this disease and its therapeutic effect. METHODS: Weighted gene co-expression network analysis (WGCNA) was performed to identify differentially expressed mRNAs (DEmRNAs) that might be key genes. GO enrichment and protein-protein interaction (PPI) analyses were performed to identify the principal functions of the DEmRNAs. An lncRNA-miRNA mRNA network was constructed to understand the regulatory mechanisms in HNSCC. The prognostic signatures of mRNAs, miRNAs, and lncRNAs were determined by Gene Expression Profiling Interactive Analysis (GEPIA) and using Kaplan-Meier survival curves for patients with lung squamous cell carcinoma. RESULTS: We identified 2,023 DEmRNAs, 1,048 differentially expressed lncRNAs (DElncRNAs), and 82 differentially expressed miRNAs (DEmiRNAs). We found that eight DEmRNAs, 53 DElncRNAs, and 16 DEmiRNAs interacted in the ceRNA network. Three ceRNAs (HCG22, LINC00460 and STC2) were significantly correlated with survival. STC2 transcript levels were significantly higher in tumour tissues than in normal tissues, and the STC2 expression was slightly upregulated at different stages of HNSCC. CONCLUSION: LINC00460, HCG22 and STC2 exhibited aberrant levels of expression and may participate in the pathogenesis of HNSCC. PMID- 30282066 TI - Inhibition of Protein Phosphatase 2A Sensitizes Mucoepidermoid Carcinoma to Chemotherapy via the PI3K-AKT Pathway in Response to Insulin Stimulus. AB - BACKGROUND/AIMS: Protein phosphatase 2A (PP2A) is a ubiquitous serine/threonine phosphatase that mediates cell cycle regulation and metabolism. Mounting evidence has indicated that PP2A inhibition exhibits considerable anticancer potency in multiple types of human cancers. However, the efficacy of PP2A inhibition remains unexplored in mucoepidermoid carcinoma (MEC), especially in locally advanced and metastatic cases with limited systemic treatment. In this study, we demonstrated the therapeutic potency of LB100 in mucoepidermoid carcinoma. METHODS: In this study, the expression of PP2A was evaluated using immunohistochemical (IHC) staining. The effects associated with LB100 alone and in combination with cisplatin for the treatment of mucoepidermoid carcinoma were investigated both in vitro, regarding metabolism, proliferation, and migration, and in vivo in a mucoepidermoid carcinoma xenograft model. In addition, with LB100 treatment and in response to an insulin stimulus, the expression levels and phosphorylation levels of targets in the PI3K-AKT pathway were determined using western blot analysis and immunoblotting. RESULTS: The expression of protein phosphatase 2A was significantly upregulated in the clinical specimens of high-grade MECs compared with those of low-/medium-grade MECs and normal controls. In this article, we report that a small molecule PP2A inhibitor, LB100, decreased cellular viability and glycolytic activity and induced G2/M cell cycle arrest. Importantly, LB100 enhanced the efficacy of cisplatin in mucoepidermoid carcinoma cells both in vitro and in vivo. PP2A inhibition by LB100 increased the phosphorylation of insulin receptor substrate 1(IRS-1) on serine residues, downregulated the expression of phosphatidylinositol 3-kinase (PI3K) p110 alpha subunit and dephosphorylated AKT at Ser473 and Thr308 in mucoepidermoid carcinoma cells in response to insulin stimulus. CONCLUSION: These results highlight the translational potential of PP2A inhibition to synergize with cisplatin in mucoepidermoid carcinoma treatment. PMID- 30282067 TI - Circular RNA Expression Profile in Laryngeal Squamous Cell Carcinoma Revealed by Microarray. AB - BACKGROUND/AIMS: A growing body of evidence has suggested that circular RNAs (circRNAs) have crucial functions in the regulation of gene expression, and their dysregulation has been implicated in various types of cancers. However, the roles of circRNAs in laryngeal cancer remain largely unknown. This study investigated the global changes in the expression pattern of circRNAs in laryngeal squamous cell carcinoma (LSCC) to identify potential differentially expressed circRNAs. METHODS: Microarray-based circRNA expression was determined in LSCC and paired normal laryngeal tissues. Pathway analyses of the genes producing differentially expressed circRNAs were performed to predict the function of circRNAs using standard enrichment computational methods. Expression levels of candidate circRNAs and microRNAs (miRNAs) were detected by quantitative real-time PCR. The circRNA/ miRNA interactions were constructed using bioinformatics methods to predict the binding of miRNA with circRNA. RESULTS: We identified 506 differentially expressed circRNAs from human LSCC and normal laryngeal mucosa tissues. We confirmed that hsa_circ_0044520 and hsa_circ_0044529 were significantly upregulated in LSCC tissues. The most likely potential target miRNAs for hsa_ circ_0044520 and hsa_circ_0044529 were hsa-miR-4726-5p and hsa miR-4640-5p, respectively. Functional analysis showed that hsa_circ_0044520 and hsa_circ_0044529 were involved in the process of collagen synthesis. CONCLUSION: Competitive endogenous RNA network prediction and bioinformatics functional analysis revealed that hsa_circ_0044520 and hsa_circ_0044529 play important regulatory roles by sponging hsa-miR-4726-5p and hsa-miR-4640-5p, thereby providing novel insights into the tumorigenesis of LSCC. PMID- 30282069 TI - Large Cytoplasmic Vacuoles within Notochordal Nucleus Pulposus Cells: A Possible Regulator of Intracellular Pressure That Shapes the Cytoskeleton and Controls Proliferation. AB - Degeneration of the intervertebral disc, which is closely associated with the loss of vacuolated notochordal nucleus pulposus cells (NNPC), remains a major cause of lower-back pain and motor deficiency. Being the most defining characteristic of NNPC, large cytoplasmic vacuoles not only modulate the cytoskeleton and shape cell morphology but they also respond to the disc microenvironment and regulate the biological behavior of vacuolated cells as a potent reporter of the histocytological changes that occur at the beginning of disc aging and degeneration. Here we hypothesize a model in which large cytoplasmic vacuoles primarily function to maintain a reasonable intracellular pressure (Pv) that facilitates NNPC in resisting the extracellular mechanical loading (Pe), part of which is absorbed by the extracellular matrix (Pm), forming the equation Pe = Pm + Pv. By mimicking a situation of contact-induced growth inhibition, the crowded cytoplasmic vacuoles slow down the proliferation of NNPC and restrain the generation of nonvacuolated chondrocytic nucleus pulposus cells (CNPC), whereas increased mechanical loading (?Pe) alters cytoskeletons and breaches cytoplasmic vacuoles, which in turn weakens the vacuoles-mediated proliferation check, increases the generation of CNPC that accumulates fibrocartilaginous matrix, and rebalances the increased loading with elevated Pm (?Pm) and lowered Pv (?Pv), equating to ?Pe = ?Pm + ?Pv. By depicting the biological function and the disappearance of the cytoplasmic vacuoles, our model highlights a mechanical exhaustion of the notochordal cell resources, which might help to elucidate the histocytological changes that initiate disc aging and degeneration. PMID- 30282068 TI - H19 Functions as a Competing Endogenous RNA to Regulate EMT by Sponging miR-130a 3p in Glioma. AB - BACKGROUND/AIMS: Glioma is one of the most devasting tumors and confers dismal prognosis. Long noncoding RNAs(lncRNAs) have emerged as important regulators in various tumors including glioma. A classic lncRNA-H19, which is found to be highly expressed in human glioma tissues and cell lines, and is associated with tumor progression thus predicating clinical outcomes in glioma patients. However, the overall biological functions and their mechanism of H19 in glioma are not fully understood. METHODS: Firstly, we analyzed H19 alterations in different grades of glioma tissues through an analysis of 5 sequencing datasets and qRT-PCR was performed to confirm the results. Next, we evaluated the effect of H19 on glioma cells migration, invasion and EMT process. Luciferase assays and RIP assays were employed to figure out the correlation of H19 and SOX4. RESULTS: H19 was overexpressed in glioma tissues. Down-regulation of H19 led to the inhibition of migration, invasion and EMT process with a reduction in N-cadherin and Vimentin. H19 and SOX4 are both direct target of miR-130a-3p. H19 could compete with SOX4 via sponging miR-130a-3p. CONCLUSION: Taken together, these results provide a possible function of H19 as an oncogene in glioma tissues and provide a potential new therapeutic strategy for human glioma. PMID- 30282070 TI - Promoter Methylation of Ezrin and its Impact on the Incidence and Prognosis of Cervical Cancer. AB - BACKGROUND/AIMS: Aberrant localization and over-expression of Ezrin have been reported to be implicated in cervical cancer (CC). Aberrant promoter methylation of some gene families may serve as potential diagnostic biomarkers for CC. In this study, we explored the correlation of promoter methylation of the Ezrin gene with the incidence and prognosis of CC. METHODS: Cervical tissues from a total of 483 patients with CC were collected from the China-Japan Union Hospital of Jilin University. Samples were assigned into four groups accordingly to pathological diagnosis, namely the control group, the cervical intraepithelial neoplasia (CIN) I group, the CIN II-III group and the CC group. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was performed to detect the mRNA expression of Ezrin. Methylation-specific polymerase chain reaction (MSP) was used to detect the promoter methylation of the Ezrin gene. The Kaplan-Meier product-limit method and the log-rank analysis were used for survival analysis, the Cox regression analysis for the prognostic factors for CC, and the logistic regression analysis for the risk factors for the occurrence of CC. RESULTS: The methylation rate of the Ezrin gene was correspondingly increased from the control, the CIN I, the CIN II-III to the CC groups. Over-expressed mRNA of Ezrin was determined in CC tissues. The mRNA expression of Ezrin was correlated with tumor size, lymphatic metastasis, pathological grade and clinical stage (FIGO). The risk factors for the occurrence of CC were the number of abortions and the promoter methylation of the Ezrin gene. Poor prognosis of CC correlated to lymphatic metastasis, higher pathological grade, higher FIGO stage and positive Ezrin promoter methylation. CONCLUSION: These findings indicate that promoter methylation of the Ezrin gene may play a crucial role in carcinogenesis, progression and prognosis of CC. PMID- 30282071 TI - Upregulation of P21-Activated Kinase 1 (PAK1)/CREB Axis in Squamous Non-Small Cell Lung Carcinoma. AB - BACKGROUND/AIMS: p21-activated Ser/Thr kinase 1 (PAK1) is essential for the genesis and development of many cancers. The purpose of this study was to investigate the role of the PAK1-cyclic AMP response element-binding (CREB) axis in non-small cell lung cancer (NSCLC) tumorigenesis and its related mechanisms. METHODS: Western blot assay and immunohistochemical staining were employed to investigate the PAK1 and CREB expression in the tissue microarray of human squamous NSCLC. Co-immunoprecipitation and immunofluorescence confocal assays were performed to determine the link between PAK1 and CREB. NSCLC xenograft models were used to study oncogenic function of PAK1 in vivo. RESULTS: We observed that PAK1 and CREB expression levels were significantly elevated in human squamous NSCLC-tissue specimens, compared with those in adjacent normal bronchial or bronchiolar epithelial-tissue specimens, as well as their phosphorylated forms, based on western blotting. We showed in vitro that PAK1 knockdown by small-interfering RNA (siRNA) blocked CREB phosphorylation, whereas plasmid-based PAK1 overexpression resulted in CREB phosphorylation at Ser133, based on western blotting. In addition, PAK1 interacted with CREB in co immunoprecipitation assays. Additionally, our in vitro findings detected by flow cytometry revealed that PAK1 silencing attenuated cell cycle progression, inducing apoptosis. Inhibition of PAK1 expression reduced tumor sizes and masses by modulating CREB expression and activation in xenograft models. CONCLUSION: These results suggest a novel mechanism whereby the PAK1-CREB axis drives carcinogenesis of squamous-cell carcinomas, and have important implications in the development of targeted therapeutics for squamous-cell lung cancer. PMID- 30282075 TI - OK-432 Treatment of Early Fetal Chylothorax: Pregnancy Outcome and Long-Term Follow-Up of 14 Cases. AB - BACKGROUND: The treatment options for fetal chylothorax include thoracocentesis, thoracoamniotic shunting, and pleurodesis using OK-432. Knowledge on the long term outcomes after treatment with OK-432 is limited. OBJECTIVE: The aim of this study was to assess the long-term outcomes of children treated in utero with OK 432. METHODS: We performed follow-up on pregnancies and children treated in utero with OK-432 between 2003 and 2009 at Copenhagen University Hospital Rigshospitalet for pleural effusions at gestational age (GA) 16+0-21+6 weeks. Anamnestic information, physical examination, pulmonary function test, neuropediatric examination, and intelligence testing using the Wechsler Intelligence Scale were used for evaluation. RESULTS: Fourteen cases, all chylothorax, were treated with OK-432. None had preterm premature rupture of membranes (PPROM), and the median GA at delivery was 38+5 (24+4-41+5) weeks. Twelve children were eligible for follow-up. The median age at follow-up was 11.4 (7.8-13.8) years. Pulmonary function was normal in all children and the mean full scale IQ did not differ from that of normal children. Four children had a diagnosed medical condition, attention deficit disorder, or genetic syndrome. The remaining children had normal follow-up. CONCLUSION: Children treated with OK-432 have comparable survival rates and long-term neurodevelopmental outcomes to those treated with thoracoamniotic shunts. There seems to be a lower risk of procedure related PPROM. PMID- 30282072 TI - MicroRNA-34a Attenuates Paclitaxel Resistance in Prostate Cancer Cells via Direct Suppression of JAG1/Notch1 Axis. AB - BACKGROUND/AIMS: Treatment options for metastatic castrate-resistant prostate cancer (mCRPC) are limited and typically centered on paclitaxel-based chemotherapy. In this study, we aimed to evaluate whether miR-34a attenuates chemoresistance to paclitaxel by regulating target genes associated with drug resistance. METHODS: We used data from The Cancer Genome Atlas to compare miR-34a expression levels in prostate cancer (PC) tissues with normal prostate tissues. The effects of miR-34a inhibition and overexpression on PC proliferation were evaluated in vitro via Cell Counting Kit-8 (CCK-8) proliferation, colony formation, apoptosis, and cell-cycle assays. A luciferase reporter assay was employed to identify the interactions between miR-34a and specific target genes. To determine the effects of up-regulation of miR-34a on tumor growth and chemo resistance in vivo, we injected PC cells overexpressing miR-34a into nude mice subcutaneously and evaluated the rate of tumor growth during paclitaxel treatment. We examined changes in the expression levels of miR-34a target genes JAG1 and Notch1 and their downstream genes via miR-34a transfection by quantitative reverse transcription PCR (qRT-PCR) and western blot assay. RESULTS: miR-34a served as an independent predictor of reduced patient survival. MiR-34a was down-regulated in PC-3PR cells compared with PC-3 cells. The CCK-8 assay showed that miR-34a overexpression resulted in increased sensitivity to paclitaxel while miR-34a down-regulation resulted in chemoresistance to paclitaxel in vitro. A study of gain and loss in a series of functional assays revealed that PC cells expressing miR-34a were chemosensitive. Furthermore, the overexpression of miR-34a increased the sensitivity of PC-3PR cells to chemotherapy in vivo. The luciferase reporter assay confirmed that JAG1 and Notch1 were directly targeted by miR-34a. Interestingly, western blot analysis and qRT-PCR confirmed that miR-34a inhibited the Notch1 signaling pathway. We found that miR-34a increased the chemosensitivity of PC-3PR cells by directly repressing the TCF1/ LEF1 axis. CONCLUSION: Our results showed that miR-34a is involved in the development of chemosensitivity to paclitaxel. By regulating the JAG1/Notch1 axis, miR-34a or its target genes JAG1 or Notch1 might serve as potential predictive biomarkers of response to paclitaxel-based chemotherapy and/or therapeutic targets that will help to overcome chemoresistance at the mCRPC stage. PMID- 30282074 TI - The Munich-Transarterial Chemoembolisation Score Holds Superior Prognostic Capacities Compared to TACE-Tailored Modifications of 9 Established Staging Systems for Hepatocellular Carcinoma. AB - BACKGROUND/AIMS: The recently proposed Munich-transarterial chemoembolisation score (M-TACE) was tailored to suit hepatocellular Carcinoma (HCC) patients evaluated for TACE. M-TACE outperformed the established HCC-staging-systems and successfully passed external validation. Modifications of staging-systems through the rearrangement of stages or by adding prognostic factors are methods of improving prognostic power. M-TACEs performance compared to scores modified this way should be tested. METHODS: Seven well-known HCC staging-systems (including Cancer of the Liver Italian Program-score [CLIP] and Barcelona Clinic liver cancer [BCLC]) and 2 TACE-specific scores (Selection for Transarterial Chemoembolisation Treatment [STATE] and Hepatoma Arterial embolisation Prognostic [HAP]) were rearranged in a cohort of 186 TACE-patients through score-point analysis and subsequent linking of non-significant adjacent score-points. Additionally, a new score was constructed by combining the top established staging-system in TACE patients (CLIP-TACE) and the prognostic parameter with the highest hazard ratio for death in the TACE-cohort [C-reactive protein (CRP)]. Additionally, the TACE-tailored-scores were applied to an external TACE-cohort (n = 71). -Results: Rearrangement resulted in optimal stratification and monotonicity. CLIP-TACE demonstrated the best prognostic capability of all rearranged scores (c-index 0.668, AIC 1294) and the addition of CRP yielded further prognostic improvement (c-index 0.680, AIC 1289). However, superiority over M-TACE could not be achieved by any of the new scores in the internal and external cohort. CONCLUSION: M-TACE outperforms TACE-tailored modifications of all relevant HCC-staging-systems. Prospective validation of M-TACE to promote its role as the preferred staging-system for TACE-patients is therefore justified. PMID- 30282076 TI - Gender, Age, and Concomitant Diseases of Colorectal Diverticulum in China: A Study of 7,964 Cases. AB - AIM: To analyze the epidemiological features of colorectal diverticulum (CRD) in China. METHODS: We retrospectively analyzed CRD patients in 8 tertiary hospitals located in 5 regions of China from 2000 to 2016. The detection rates, number and distribution, demographic information, concomitant disorders, and their associations were investigated. RESULTS: Of 3,446,118 cases, 7,964 (2.3%) were CRD with a mean age of 56 years (11-92 years). The detection rate increased yearly and with increasing age. Males had a higher detection rate than females (3.0 vs. 1.47%, p < 0.01) and 1.8-times higher increase rate. The detection rate increased with age; however, females of > 60 years had a 2.8-times increasing rate than males. CRD occurred most frequently in the right-side colon, followed by rectum. Multiple diverticula were common in males and increased with age, with a 3-times higher increase rate than single lesion. Single-segment CRD occurred more frequently in males than in females (80.1 vs. 76.4%, p < 0.01). Concurred colon polyps were seen in 51.05% cases. CONCLUSION: CRD detection rates increased annually and with age, particularly in senior females in China. Multiple diverticula were common in males and increased with age. CRD was predominant in the right-side colon. Polyps are the most common comorbidity associated with CRD. PMID- 30282077 TI - Effects of Sodium Hyaluronate on Symptoms and Quality of Life in Women Affected by Pregnancy Rhinitis: A Pilot Study. AB - AIMS: To investigate sodium hyaluronate (SH) efficacy in the treatment of pregnancy rhinitis. METHODS: A single-center, prospective, open-label, 2 parallel group study was carried out. Pregnant women affected by pregnancy rhinitis were randomly assigned to 1 of 2 groups: Group A was treated with SH, while Group B did not receive any treatment. Pregnancy rhinitis symptoms and quality of life (QOL) during pregnancy were investigated by administering a questionnaire and carrying out an otorhinolaryngoiatric visit. RESULTS: A significant reduction in the intensity of headache, snoring and insomnia in the Group A compared to the Group B were demonstrated. In the Group A, a significant lower presence of amount of secretions (Group A 0.88, 95% CI 0.57-1.18 vs. Group B 2.00, 95% CI 1.69-2.31, p < 0.001), turbinate hypertrophy (Group A 1.70, 95% CI 1.46-1.94 vs. Group B 2.53, 95% CI 2.29-2.77, p < 0.001), and mucosal congestion/hyperemia (Group A 1.41, 95% CI 1.14-1.68 vs. Group B 2.26, 95% CI 1.99-2.53, p < 0.001) was observed. No adverse events were reported in patients treated with SH. CONCLUSIONS: SH is a safe and effective therapeutic alternative for the treatment of pregnancy rhinitis symptoms, improving patients' QOL. PMID- 30282073 TI - Divergent Effects of Cyclophilin-D Inhibition on the Female Rat Heart: Acute Versus Chronic Post-Myocardial Infarction. AB - BACKGROUND/AIMS: The mitochondrial permeability transition pore opening plays a critical role in the pathogenesis of myocardial infarction. Inhibition of cyclophilin-D (CyP-D), a key regulator of the mitochondrial permeability transition pore, has been shown to exert cardioprotective effects against ischemia-reperfusion injury on various animal models, mostly in males. However, failure of recent clinical trials requires a detailed elucidation of the cardioprotective efficacy of CyP-D inhibition. The aim of this study was to examine whether cardioprotective effects of sanglifehrin A, a potent inhibitor of CyP-D, on post-infarcted hearts depends on reperfusion. METHODS: Acute or chronic myocardial infarction was induced by coronary artery ligation with/without subsequent reperfusion for 2 and 28 days in female Sprague-Dawley rats. Cardiac function was estimated by echocardiography. Oxygen consumption rates, ROS production, permeability transition pore opening, protein carbonylation and respiratory supercomplexes were analyzed in isolated cardiac mitochondria. RESULTS: Sanglifehrin A significantly improved cardiac function of reperfused hearts at 2 days but failed to protect after 28 days. No protection was observed in non-reperfused post-infarcted hearts. The respiratory control index of mitochondria was significantly reduced in reperfused infarcted hearts at 2-days with no effect at 28-days post-infarction on reperfused and non-reperfused hearts. Likewise, only a minor increase in reactive oxygen species production was observed at 2-days in non-reperfused post-infarcted hearts. CONCLUSION: This study demonstrates that CyP-D inhibition exerts cardioprotective effects in reperfused but not in non-reperfused infarcted hearts of female rats, and the effects are observed only during acute post-infarction injury. PMID- 30282078 TI - Endoscopic Retrograde Cholangio-Pancreatography-Obtained Bile Culture Can Guide Antibiotic Therapy in Acute Cholangitis. AB - BACKGROUND: Only a small proportion of patients with biliary tree infection grow microorganisms in blood cultures. Antibiotics chosen or tailored based on organisms identified on blood cultures have a potential for under-treatment and unfavorable outcomes, including recurrent infection and early stent occlusion. In our current practice, we collect bile for culture if an Endoscopic Retrograde Cholangio-Pancreatography (ERCP) is performed in patients with suspected cholangitis. In this study, we compare the microbial yield of blood cultures and ERCP-obtained bile cultures in patients with ascending cholangitis. METHODS: We reviewed medical records of all the patients treated for ascending cholangitis who had blood cultures and ERCP-obtained bile cultures at a tertiary care center between 2010 and 2016. Bile was collected for culture before injecting contrast, via a catheter after discarding the initial 3 mL. RESULTS: Ninety-three patients were included with mean age of 71 (+/-15) years. Out of 93 patients, 11 (12%) had prior sphincterotomy, 29 (31%) had an indwelling biliary stent, and malignant obstruction was the most common etiology (34%). ERCP-obtained bile cultures were positive in 90 out of 93 (97%) patients with monomicrobial growth in 34 out of 93 (39%) patients. Mixed intestinal flora was noted in 3 patients. Blood cultures were positive in only 30 out of 93 patients (32%) and 24 out of 93 (26%) patients had monomicrobial growth. Totally 26 out of 30 patients (87%) grew the same organism as the bile culture, 3 grew an organism different from bile cultures, and one had no growth in the bile culture. On multivariable analysis, the presence of an indwelling biliary stent was the lone factor associated with polymicrobial growth, 83 vs. 52%, p = 0.007. CONCLUSION: ERCP-obtained bile cultures are a reliable and feasible mechanism to evaluate patients with suspected biliary tree infection. This technique has a significantly higher yield when compared to blood culture. Selection and tailoring of antibiotics based on bile culture in the management of ascending cholangitis are advised. PMID- 30282080 TI - Precision Medicine Made with Silicone. PMID- 30282079 TI - Risky Alcohol Use: The Impact on Health Service Use. AB - OBJECTIVE: To examine health services use on the basis of alcohol consumption. MATERIAL AND METHODS: A cross-sectional study was carried out on patients visiting the Primary Health Care (PHC) settings in Catalonia during 2011 and 2012; these patients had a history of alcohol consumption. Information about outpatient visits in the PHC setting, hospitalizations, specialists' visits and emergency room visits for the year 2013 was obtained from 2 databases (the Information System for the Development of Research in PHC and the Catalan Health Surveillance System). Risky drinkers were defined as those who consumed more than 280 g per week for men or more than 170 g per week for women, or any amount of alcohol while being involved in a high risk work activity, or taking medication that significantly interferes with alcohol or when being pregnant. Binge drinkers (> 60 g in men or > 50 g in women in a short amount of time more than once a month) were also considered risky drinkers. RESULTS: A total of 606,948 patients reported consuming alcohol (of which 10.5% were risky drinkers). Risky drinkers were more likely to be admitted to hospitals or emergency departments (range of ORs 1.08-1.18) compared to light drinkers. Male risky drinkers used fewer PHC services than male light drinkers (OR 0.89, 95% CI 0.87-0.92). In general, risky alcohol users used services more and had longer hospital stays. When stratifying by socioeconomic level of the residential area, we found that risky drinking failed significance, while current or past cigarette smoking was associated with higher healthcare use. CONCLUSIONS: Risky drinkers use more expensive services, such as hospitals and emergency rooms, but not PHC services, which may suggest that prevention strategies and alcohol interventions should also be implemented in those settings. PMID- 30282081 TI - Zone Formation of Lymphocyte Infiltration at Invasive Front as a Biomarker of Prognosis in Endometrial Carcinomas. AB - OBJECTIVE: The clinical significance of lymphocyte infiltration (LI) at the invasive front in endometrial carcinomas (EC) has not been determined. The aim of the current study was to evaluate the association between zone formation of LI at the invasive front of the tumor margin and prognoses of the patients with EC. METHODS: All available pathological slides of the enrolled cases were reviewed, and the degree of LI at the invasive front was categorized into 2 groups: strong LI and weak LI. Clinical significance of LI was evaluated retrospectively. RESULTS: A total of 333 cases with EC were enrolled in the study: 225 cases with weak LI and 108 cases with strong LI. Weak LI was more frequently observed in the patients with grade1/2 endometrioid EC. Multivariate analyses for progression free survival (PFS) and overall survival (OS) revealed that weak LI was identified as an independent worse prognostic factor for OS (p = 0.004) in addition to PFS (p = 0.022). CONCLUSION: Weak LI at the invasive front of the tumor margin was associated with worse prognoses in EC. Although further studies are needed, it is suggested that LI could be a biomarker of prognoses in EC. PMID- 30282082 TI - Neuroendocrine Breast Carcinomas Share Prognostic Factors with Gastroenteropancreatic Neuroendocrine Tumors: A Putative Prognostic Role of Menin, p27, and SSTR-2A. AB - OBJECTIVES: Due to the rarity of breast carcinomas with neuroendocrine features (NEBC), the knowledge on their biology is very limited but the identification of their biology and prognostic factors is essential to evaluate both pathogenesis and possible targeted treatment options. We assessed the expression of the well characterized prognostic factors of gastroenteropancreatic neuroendocrine tumors (GEP-NET) in NEBC. METHODS: We assessed the immunohistochemical expression of neuron-specific enolase (NSE), thymidylate synthase (TS), p27, CD56, menin, and somatostatin receptor type 2A (SSTR-2A) in a series of 36 NEBC and 45 invasive ductal carcinomas (IDC). RESULTS: Nuclear and cytoplasmic TS, nuclear and cytoplasmic NSE, and nuclear p27 had significant overexpression in NEBC compared with IDC (for all, p < 0.01). In NEBC, cytoplasmic SSTR-2A expression was associated with excellent distant disease-free survival (p = 0.013), cytoplasmic menin expression with poorer relapse-free survival (p = 0.022), and nuclear p27 with longer breast cancer-specific survival (p = 0.022). CONCLUSIONS: There is a striking similarity in GEP-NET and NEBC regarding prognostic factors. GEP-NET and NEBC also appear to show similar expression patterns of the studied markers, while there are notable differences compared to IDC. Due to the wide expression of SSTR-2A, the treatment option with somatostatin analogs in NEBC should be evaluated.

AB - Recently, European Neuroendocrine Tumor Society (ENETS )held working sessions composed of members of the advisory board and other Neuroendocrine neoplasms (NEN) experts to attempt to identify unmet needs in NENs in different locations or with advanced/poorly differentiated NENs. This section briefly summarizes the main proposed areas of unmet needs in patients with functional and non-functional pancreatic neuroendocrine neoplasms (PanNENs). PMID- 30282084 TI - Fits of Implant Zirconia Custom Abutments and Frameworks: A Systematic Review and Meta-Analyses. AB - PURPOSE: The aim of this systematic review and meta-analyses was to evaluate fits of zirconia custom abutments and frameworks on implants and to identify the factors that influence their fits. MATERIALS AND METHODS: An electronic search was conducted through PubMed (MEDLINE), Google Scholar, and Cochrane Central Registrar of Controlled Trials. The search was completed in August 2017. Series of meta-analyses were conducted to compare fits of zirconia custom abutments and frameworks on implants with metal abutments and frameworks. The interest variables were the interface gap and the rotational misfit of abutments and the vertical fit of frameworks. RESULTS: Initially, a total of 672 articles were identified from the electronic search. After applying the inclusion criteria, 17 suitable articles were selected, including 9 studies on the fit of zirconia custom abutments and 8 studies on the fit of zirconia frameworks. There is a tendency for zirconia abutments to exhibit greater interface gaps and rotational misfits than metal abutments. Abutments produced by manual-aided designs/manual aided manufacturing (MAD/MAM) exhibited inferior fits compared with those produced by computer-aided design/computer-aided manufacturing (CAD/CAM). Proprietary abutments had superior fits compared with non-proprietary abutments. Milled zirconia frameworks had insignificantly inferior fits compared with milled metal frameworks. CONCLUSION: Within the limitations of this study, custom zirconia abutments and non-proprietary abutments appeared to exhibit slightly inferior fits compared with metal abutments or abutments produced by the same implant company. However, the clinical significance of this difference is yet to be determined. The fit of milled zirconia frameworks is generally comparable to milled metal frameworks.

AB - PURPOSE: This study aimed to perform a systematic review and meta-analysis of the literature on the mandibular incisive canal (MIC) studies using cone beam computed tomography (CBCT). MATERIALS AND METHODS: A PROSPERO-registered systematic review (#42017056619) was conducted following the PRISMA statements to summarize current knowledge on the CBCT aspects of the MIC. A search was performed in PubMed's Medline and Scopus databases, without date or language restrictions, using the algorithm {[(Interforaminal region) OR (mandibular incisive channel) OR (mandibular incisive nerve) OR (mental mandible) OR (anterior mandible) (cone beam computed tomography). Also, the references were crosschecked. The Meta-Analysis of Statistics Assessment and Review Instrument and meta-analysis was used to evaluate the selected studies. RESULTS: A total of 410 articles were found, and 25 studies were selected after a two-step selection process. The CBCT systems differed regarding field of view (FOV) (large, n = 3; medium, n = 2; small, n = 4; not informed, n = 16) and voxel size (0.15 to 0.4 mm). Geographically, the studies were distributed across four continents (South America, North America, Asia, and Europe), and there was a statistical significance of studies from the American and Asian continents (P < .0001). From 3,421 CBCT exams, the number of female patients was slightly higher than male, and the mean age ranged from 29.8 to 59.1 years. The overall mean prevalence of MIC was 89.6% +/- 15.08%, and bilateral occurrence was statistically significant (P < .0001). The studies using a voxel size lower than 0.3 mm showed the highest mean prevalence (93.88%) in comparison with voxel size described as >= 0.3 mm (89.33%). Diameter (0.45 to 4.12 mm) and length (6.6 to 40.3 mm) showed great variability among the included studies. CONCLUSION: In summary, the results of this systematic review evidenced a high worldwide prevalence of MIC. There was no prevalence of MIC in relation to sex, and its presence was mainly related to adults between the fourth and sixth decades of life. In addition, great heterogeneity of methodologies was observed. PMID- 30282086 TI - Hard and soft tissue cell behavior on PEEK, Zirconia, and Titanium implant materials. AB - PURPOSE: The aim of this study was to characterize and compare the behavior of human osteoblasts and human gingival fibroblasts in contact with polyetheretherketone (PEEK), zirconia, and titanium implant surface materials. MATERIALS AND METHODS: PEEK, yttria-stabilized zirconia (YTZP), and titanium discs were produced under appropriate and similar conditions to achieve controlled surface features. Human osteoblasts and human gingival fibroblasts were cultured on discs for 14 days. Cell viability and proliferation were evaluated using a resazurin-based method. Morphology and cellular adhesion were observed using field emission gun-scanning electron microscopy (FEG-SEM). Alkaline phosphatase (ALP) activity and bone cell mineralization were evaluated on osteoblasts. Confocal laser scanning microscopy (CLSM) images of fluorescent stained fibroblasts were obtained at 7 and 14 days of the culture. Results were presented as mean and standard deviation (SD). Group comparisons were tested using analysis of variance (ANOVA) (Tukey's post hoc) with appropriate statistical software, and significance was set at P < .05. RESULTS: Cell viability and proliferation were higher in PEEK and YTZP groups compared with titanium on osteoblast cells (P < .05, all time points) and on fibroblasts (P < .05, 7 and 14 days). All groups showed an increase in ALP activity over time, which was not significant. Mineralization patterns demonstrated an increase in mineral content over time, which was more apparent in the YTZP group. Cell spreading was more evident on PEEK and YTZP specimens. CONCLUSION: The results suggest increased adhesion, viability, and proliferation of osteoblasts and gingival fibroblasts on zirconia and PEEK surfaces compared with titanium. These results are correlated with the increased wettability of these materials. PMID- 30282087 TI - An Evaluation of the Relationship Between Peri-implant Soft Tissue Biotype and the Severity of Peri-implantitis: A Cross-Sectional Study. AB - PURPOSE: This cross-sectional study aimed to analyze the relation between peri implant soft tissue biotype (STB) and different levels of peri-implantitis severity, and to identify the possible risk indicators that affect the severity of peri-implantitis with regard to STB around dental implants. MATERIALS AND METHODS: Eighty-seven patients with 229 implants were diagnosed with peri implantitis and recruited to the study. Clinical and radiographic parameters including Plaque Index (PI), probing depth (PD), bleeding on probing (BOP), gingival/mucosal recession (GR/MR), clinical attachment level (CAL), and marginal bone loss (BL) were analyzed. The periodontal status was assessed, and the levels of peri-implantitis severity were defined. These parameters were compared among the peri-implant STB groups (thick and thin biotype). To evaluate the effect of possible risk indicators on the levels of severity of peri-implantitis, univariate and multivariate logistic regression analyses were conducted for thick and thin biotype groups. RESULTS: The mean values of BOP, MR, CAL, and marginal BL were significantly lower for the thick group compared with the thin group (P < .05). For PI and PD values, no significant differences were found between the groups (P > .05). Moreover, multivariate analysis revealed statistically significant associations between peri-implantitis severity and the risk indicators maintenance therapy compliance and current periodontitis for the thin group (P < .05). CONCLUSION: The thin biotype could be more prone to increase in the severity of peri-implantitis. Maintenance therapy compliance and current periodontitis could be important risk indicators that affect the progression of the severity of peri-implantitis for implants where keratinized mucosa is thin or absent. PMID- 30282088 TI - Radiographic Assessment Of Crestal Bone Loss In Tissue-Level Implants Restored By Platform Matching Compared With Bone-Level Implants Restored By Platform Switching: A Randomized, Controlled, Split-Mouth Trial With 3-Year Follow-Up. AB - PURPOSE: This randomized, controlled, split-mouth trial with 3-year follow-up was carried out to compare radiologic changes of crestal bone level (CBL) between splinted tissue-level implants restored by platform matching and bone-level implants restored by platform switching. MATERIALS AND METHODS: Periapical radiographs were taken to evaluate the peri-implant crestal bone changes at baseline (implant restoration), at 1 year, and at 3 years after the definitive restoration. RESULTS: Thirty-five patients requiring a partial fixed dental prosthesis supported by two implants had their sites randomized according to receiving both implant types. Fifty tissue-level implants restored by platform matching, as control implants, and 50 bone-level implants restored by platform switching, as test implants, were placed. Crestal bone changes in the control group were: baseline to 3 years, 0.18 +/- 0.46 mm (P = .043). In the test group, crestal bone changes were: baseline to 3 years, 0.14 +/- 0.35 mm (P = .514). The mean differences between groups were: baseline to 1 year, 0.07 +/- 0.23 mm (95% CI: -0.034, 0.185); 1 to 3 years, 0.01 +/- 0.01 mm (95% CI: -0.055, 0.074); baseline to 3 years, 0.04 +/- 0.11 mm (95% CI: -0.080, 0.150). No statistically significant differences in CBL at baseline to 1 year (P = .269), 1 year to 3 years (P = .811), and baseline to 3 years (P = .513) were observed. CONCLUSION: In this trial, CBL changes in the tissue level control group were statistically significant only between baseline and 3-year follow-up. Meanwhile, CBL changes in the bone-level test group were not statistically significant in the different times studied. No statistically significant difference in CBL between two implant types was observed. PMID- 30282089 TI - Resonance Frequency Analysis: Agreement and Correlation of Implant Stability Quotients Between Three Commercially Available Instruments. AB - PURPOSE: The purpose of this study was to analyze the implant stability quotient (ISQ) values recorded by three commercially available resonance frequency analysis (RFA) instruments from a large cohort of implants in order to determine their accuracy and agreement with one another both for static measurements of ISQ at a given time and for change in ISQ over time. MATERIALS AND METHODS: A cohort of n = 210 implants had their primary stability, secondary stability, or both evaluated in both the mesiodistal (MD) and buccolingual (BL) directions by means of ISQ using three different RFA instruments: Osstell Mentor (OM), Osstell Idx (OI), and the Penguin (PG). ISQ values were recorded both at the time of implant placement and at 3 months postinsertion prior to definitive restoration. All values were tabulated for a blinded statistical analysis using Bland Altman plots to determine if the outcome values were in agreement both for primary and secondary stability. In addition, a subgroup was evaluated to determine if change in ISQ was also in agreement. An intraclass correlation (ICC) was used to measure the reliability of the measurements for each instrument. RESULTS: Bland Altman plots confirmed that there was a high agreement for MD values between OM and OI, with 72.7% of readings being within one ISQ unit and 94.7% within four units. Comparing PG to OM, the respective values at one and four units were 15.3% and 82.3%, and comparing PG to OI, the respective values were 16.3% and 85.2%. In general, there was a greater uncertainty in the BL values having wider variability and demonstrating less agreement between instruments, with the percentage of readings falling within four units reducing to 85.9% (OM vs OI), 72.3% (PG vs OM), and 74.3% (PG vs OI). 92.3% of values were in agreement to within four units between instruments OM and OI for change in ISQ over time in the MD direction and 73% in the BP direction. The respective percentage changes of values in agreement within four units for PG vs OM were 76.9% and 60.3% and for PG vs OI were 80% and 53.8%. Paired t test from mixed effects revealed that there was a significant difference for mean MD values between PG vs OM; P = .015 with on average 0.823 units higher was recorded for PG. Similarly for PG vs OI, P = .008 with on average 0.871 units higher was recorded for PG. For mean BL values between PG vs OI, P = .000 with on average 1.161 units higher was recorded for PG, and finally, for OM vs OI, P = .005 with on average 0.597 units higher was recorded for OM. However, the maximum upper and lower bound estimated bias between any two instruments was only 1.86 units and 0.46 units both for PG vs OI in the BP direction, and it is doubtful that this is of clinical relevance even if statistically significant. ICC revealed that for static MD measurements, there was an 85% reliability between all three instruments. The highest reliability was between OM and OI instruments (97%), and the lowest reliability was when comparing results between PG and OM instruments (79%). For BL measurements, these reliability values were 66%, 71%, and 69%, respectively. When considering ICC for changes in ISQ values over time in the MD direction, there was a 70% reliability between all three instruments. The highest reliability was between OM vs OI instruments (94%), and the lowest reliability was when comparing results between PG vs OM instruments (58%). For BL measurements, these reliability values were 58%, 91%, and 46%, respectively. CONCLUSION: Differences exist between all three instruments to a greater or lesser extent, with the most notable differences between the Penguin and the two instruments from Osstell, which showed both good agreement and reliability to each other. While the differences apparent in evaluating ISQ with the Penguin were statistically significant, they were less than 1.86 units at the upper bound limit, and it is doubtful that this is of clinical significance. Of greater clinical importance is the much-increased variability and reduced reliability for BL values as to render these less clinically sound compared with MD values when trying to assess primary stability. PMID- 30282091 TI - Anatomical and Biologic Considerations of Autogenous Bone Blocks Harvested from the Ramus Region. AB - A common site to harvest autogenous bone is the posterior mandible (ramus). Bone from this area may be cortical or cancellous in nature with different levels of osteogenic potential. Management of deficient alveolar ridges must be based upon anatomical and biologic characteristics of the donor bone from the ramus. This technical report provides all aspects of the presurgical planning, topographic features of autogenous ramus blocks, and loading concepts according to the biologic characteristics and resorption properties of these blocks. Long-term data from clinical cases are presented improving the clinical outcomes with high predictability. PMID- 30282090 TI - Clinical Outcome Of Dental Implant Therapy In Association With Le Fort I Osteotomy Preprosthetic Surgery: A Systematic Review. AB - PURPOSE: The purpose of this systematic review was to evaluate the outcome of dental implant treatment in fully edentulous patients who underwent Le Fort I osteotomy as a preprosthetic surgical technique. MATERIALS AND METHODS: A search was conducted of the PubMed (MEDLINE), EMBASE, Scopus, and Cochrane databases to identify records published from 1995 to 2017 dealing with Le Fort I osteotomy procedures for implant placement purposes. The primary outcomes of interest were the survival and success rates. The secondary outcomes consisted of the analysis of intra- and postsurgical complications and the surgical and prosthetic loading protocols. RESULTS: Overall, 20 articles were selected for data analysis. A total of 483 patients accounting for 3,596 implants were analyzed. The cumulative survival rate was 90.22% +/- 0.8% at 10 years (mean: 59.20 +/- 32.31 months). The cumulative success rate was 89.07% +/- 1.3% at 10 years (mean: 62.82 +/- 25 months). Higher survival rates were found for implants with a rough surface (P < .001) and for implants loaded with a delayed protocol (P < .001). The fracture of the palatine bone during the downfracture procedure was the main intrasurgical drawback, while sinus pathology and graft resorption were commonly observed during the postoperative healing. Surgical and prosthetic loading protocols were heterogenous. CONCLUSION: Based on this review, Le Fort I osteotomy might be considered a viable technique to recreate favorable conditions for implant supported rehabilitations. Caution has to be taken when using machined implants, particularly in the case of a simultaneous approach. PMID- 30282092 TI - The implant surface and its role in affecting the dynamic processes of bone remodeling by means of distance osteogenesis: A comparative in vivo study. AB - PURPOSE: This study aimed to evaluate whether different surface modifications affect the dynamics of bone remodeling at the implant and the adjacent local bone. MATERIALS AND METHODS: Seventy-two dental implants with different surfaces (smooth and rough control [smCtrl; rCtrl], smooth and rough + O2-plasma spray [smPlas; rPlas], smooth and rough + nanocrystalline SiO2-hydroxyapatite coating [ncSiO2HA] + O2-plasma spray [smNB-C; rNB-C]; each n = 12) were bilaterally inserted into the femora of 36 New Zealand white rabbits. Intravital fluorochrome labeling was performed to visualize the dynamics of bone formation. The objectives were quantification of bone-to-implant contact (BIC [%]) at 2 and 4 weeks and the dynamic bone formation (dbf [%]) at the implants' adjacent local bone within 1, 2, and 3 weeks. RESULTS: After 2 weeks, BIC was significantly higher for both smNB-C (BIC: 59% +/- 2% SEM) and rNB-C (BIC: 66% +/- 3% SEM) compared with controls (BIC: 42% +/- 1% SEM; P < .005). After 4 weeks, BIC for rNB-C (65% +/- 2%) was superior to all test groups (BIC: 39% +/- 2% SEM; P = .012). Regarding dbf (%), neither within 1 (P = .88), 2 (P = .48), nor after 3 weeks (P = .36) did any differences occur among the groups, even in accordance to the implant level. CONCLUSION: Although distance osteogenesis seems crucial for the development of secondary stability and thus of osseointegration, it apparently does not get affected by a bioactive ncSiO2HA surface coating. Changing the surfaces' release kinetics and composition may increase distance osteogenesis. PMID- 30282093 TI - A simplified soft tissue management for peri-implant bone augmentation. AB - PURPOSE: This case series illustrates a simplified soft tissue management, namely, the subperiosteal peri-implant augmented layer (SPAL), to increase hard and soft tissue dimensions at the most coronal portion of an implant. MATERIALS AND METHODS: Twenty-seven implants in 16 patients presenting either a buccal bone dehiscence or a thin (< 1 mm) buccal cortical bone plate (BCBP) were consecutively treated. Briefly, a split-thickness flap (namely, the mucosal layer) was raised on the buccal aspect. Then, the periosteal layer was elevated from the bone crest. A full-thickness flap was elevated on the oral aspect. After implant site preparation, a xenograft was used to fill the space between the periosteal layer and the BCBP and/or exposed implant surface and, if present, to completely correct the bone dehiscence. The periosteal layer was sutured to the oral flap. The mucosal layer was coronally advanced and sutured to submerge both the graft and the implants. At 3 to 6 months, a re-entry procedure for implant exposure was performed. RESULTS: Healing was uneventful, with no signs of infection in all cases. A wound dehiscence was observed in three implants in two patients at 2 weeks postsurgery. Out of 15 implants showing an initial bone dehiscence, 12 implants (80%) showed a complete resolution, with a subperiosteal tissue thickness (SPTT) at the time of re-entry of 3.1 +/- 1.0 mm. Three implants presented a residual dehiscence of 1 mm (two implants) or 2 mm (one implant), with a SPTT of at least 2 mm. Out of 12 implants showing a thin BCBP at implant placement, 10 implants (90%) revealed a SPTT >= 2 at the time of re-entry. Two implants revealed a SPTT of 1 mm. CONCLUSION: The SPAL technique represents a valuable simplified surgical approach associated with a low rate of complications in the treatment of peri-implant bone dehiscence and in the horizontal augmentation of peri-implant tissue thickness. PMID- 30282095 TI - Exercise and Air-Travel-Induced Alterations in Blood Hemostasis. AB - Hemostasis is the ability of the body to control blood loss following vascular injury. The process is composed of a complex array of pathways made up of the coagulation and fibrinolytic systems that allow the fluid blood to clot after injury and then the subsequent breakdown of the clot, permitting repair of the injured tissue. Studies to date have shown exercise to be a stimulating factor in both the coagulation and fibrinolytic pathways. Additionally, air travel has been shown to be a risk factor for thrombosis. However, few studies have examined the combination of exercise and air travel on hemostasis, despite documented evidence of venous thrombotic episodes in the sports and endurance (marathon/triathlon) communities. This review summarizes and analyzes the literature with regard to (1) acute and chronic exercise, (2) air travel, and (3) exercise and air travel. In addition, the review examines confounding variables that may contribute to coagulation and strategies to prevent blood clot formation after exercise and during air travel. PMID- 30282094 TI - The Use of Health Information Exchange to Augment Patient Handoff in Long-Term Care: A Systematic Review. AB - BACKGROUND: Legislation aimed at increasing the use of a health information exchange (HIE) in healthcare has excluded long-term care facilities, resulting in a vulnerable patient population that can benefit from the improvement of communication and reduction of waste. OBJECTIVE: The purpose of this review is to provide a framework for future research by identifying themes in the long-term care information technology sector that could function to enable the adoption and use of HIE mechanisms for patient handoff between long-term care facilities and other levels of care to increase communication between providers, shorten length of stay, reduce 60-day readmissions, and increase patient safety. METHODS: The authors conducted a systematic search of literature through CINAHL, PubMed, and Discovery Services for Texas A&M University Libraries. Search terms used were ("health information exchange" OR "healthcare information exchange" OR "HIE") AND ("long term care" OR "long-term care" OR "nursing home" OR "nursing facility" OR "skilled nursing facility" OR "SNF" OR "residential care" OR "assisted living"). Articles were eligible for selection if they were published between 2010 and 2017, published in English, and published in academic journals. All articles were reviewed by all reviewers and literature not relevant to the research objective was excluded. RESULTS: Researchers selected and reviewed 22 articles for common themes. Results concluded that the largest facilitator and barrier to the adoption of HIE mechanisms is workflow integration/augmentation and the organizational structure/culture, respectively. Other identified facilitator themes were enhanced communication, increased effectiveness of care, and patient safety. The additional barriers were missing/incomplete data, inefficiency, and market conditions. CONCLUSION: The long-term care industry has been left out of incentives from which the industry could have benefited tremendously. Organizations that are not utilizing health information technology mechanisms, such as electronic health records and HIEs, are at a disadvantage as insurers switch to capitated forms of payment that rely on reduced waste to generate a profit. PMID- 30282096 TI - Onlay Reconstruction of the Posterior Cruciate Ligament: Biomechanical Comparison of Unicortical and Bicortical Tibial Fixation. AB - Posterior cruciate ligament (PCL) injuries are generally associated with high energy trauma. There are many controversies regarding optimal surgical technique in regard to graft selection and fixation methods. The recently described onlay technique allows for direct fixation of a hamstring autograft to the posterior aspect of the tibia with cancellous screw and spiked washer, while protecting the neurovascular structures and avoiding the so-called "killer turn." The objective of this study was to compare immediate postimplantation biomechanics of unicortical versus bicortical tibial fixation of onlay PCL grafts. Eight knees were randomly assigned to one of two onlay PCL techniques (n = 4 knees/technique), performed by a single experienced surgeon. Testing consisted of a posterior-directed force at four knee flexion angles, 10, 30, 60, and 90 degrees, to measure load to 5 mm of posterior displacement, maximum displacement (at 100 N load), and stiffness. For statistical analyses, data for each knee were normalized to the native PCL-intact knee and were then grouped into unicortical or bicortical groups accordingly. Data for load to 5 mm (strength), displacement at 100 N, and stiffness were compared among PCL-intact, PCL-deficient, unicortical fixation, and bicortical fixation categories using one-way analysis of variance to assess for statistically significant (p < 0.05) differences. When compared with PCL-deficient knees, both fixation techniques had less laxity. When compared with PCL-intact knees, unicortical had more laxity at all angles, and bicortical had more laxity only at 90 degrees (p < 0.001). For relative graft strength, intact knees required significantly higher loads than both treatment groups. Bicortical, however, outperformed unicortical at all angles (p < 0.001) for relative strength. Regarding stiffness, there were no significant differences between unicortical and bicortical, and both were superior to PCL-deficient and inferior to PCL-intact knees. Based on cadaveric biomechanical testing, none of the reconstructed PCL knees was able to replicate the intact native PCL, but both techniques were superior to PCL-deficient knees. The bicortical tibial fixation technique appears to have biomechanical advantages when opting for onlay PCL reconstruction. PMID- 30282097 TI - All-Polyethylene Tibial Components in Total Knee Replacement: Early Failures. AB - In total primary knee replacement surgery, the use of all-polyethylene tibial (APT) components has many advantages, including no backside wear and no linear dissociation. In addition, the greater polyethylene thickness permits more conservative bone resection compared with that for metal-backed components, with a lower unit cost and similar functional results. Thus, the use of an APT in primary total knee arthroplasty remains an attractive option. This is a review of 158 patients who underwent primary knee replacement using APT components from a single manufacturer. Data collection included age, American Society of Anesthesiology physical status classification, body mass index (BMI), type of deformity, the presence of diabetes mellitus, rate of revision, and characteristics associated with early failure of the components. Average follow up time was 40 months. The revision rate for any reason was 5.6%, and the average BMI in revision cases was 37.6. Patients with a higher BMI (>= 37.6) were significantly more likely to require revision surgery than patients with a lower BMI (p = 0.04). In our sample, high BMI was a contributing factor for early failures in total knee replacements using an APT component. Generally, polyethylene tibial components used for primary knee replacements are safe and effective, with good outcomes and subsequent lower costs to the health care system. PMID- 30282098 TI - Periprosthetic Fracture following Partial Knee Arthroplasty. AB - Partial knee arthroplasty is a procedure with long-term successful outcomes. However, there are several potential complications including retained cement fragments, bearing dislocation, infection, component loosening, medial collateral ligament injury, and overcorrection, leading to progressive arthritis. Periprosthetic fracture is an uncommon complication, with multiple reports showing an incidence of less than 1%. Hence, there are no established algorithms to guide treatment. A consecutive series of 2,464 patients who underwent partial knee arthroplasty between January 2009 and April 2017 was reviewed. We identified 16 patients with early periprosthetic fracture, with an incidence of 0.6%. All of these were tibial fractures, which occurred at a mean of 35 days postoperatively. There were 5 males and 11 females, with an average age of 70 years at the time of surgery. Average follow-up was 62 months. Two patients had contralateral compartment insufficiency fractures that were successfully treated nonoperatively, five patients immediately underwent total knee arthroplasty (TKA), and nine patients underwent open reduction internal fixation (ORIF). Two of these cases had a failed ORIF and required conversion to TKA. Seven patients were successfully treated with a medial buttress plate in compression. Average Knee Society Score at final follow-up was 81, and average flexion was 115 degrees, with no patients having greater than 5-degree flexion contracture. Periprosthetic fracture following partial knee arthroplasty resulted in a high rate of conversion TKA. However, ORIF in select patients resulted in fracture healing and retention of the partial knee replacement. All patients were successfully treated with low complication rates, excellent range of motion, and acceptable knee scores at final follow-up. PMID- 30282099 TI - Clinical Results after Combined Distal Femoral Osteotomy in Patients with Patellar Maltracking and Recurrent Dislocations. AB - The purpose of this study is to analyze the clinical results after treatment of patellofemoral instability and maltracking caused by torsional or axial deformities of the lower extremity by combined distal femoral osteotomies (DFOs). We analyzed 31 DFOs (25 patients) with patellar maltracking and instability, treated in our clinic. Torsional angles and the leg axis in the frontal plane were measured preoperatively. Standardized scoring systems were determined pre- and postoperatively including a clinical examination. Nineteen cases of torsional and 12 cases of axis deformities were evaluated 27 (12-64) months postoperatively. Among those with torsional deformity, mean femoral torsion was 39.0 +/- 8.8 degrees, tibial tuberosity to trochlear groove (TT-TG) 20.3 +/- 4.5 mm. We performed 19 torsional (+11.4 +/- 2.4 degrees) DFOs with medial patellofemoral ligament (MPFL) augmentation (n = 19), tibial tuberosity transfer (n = 14, 10.9 +/- 6.0 mm), varus (n = 4, 3.3 +/- 1.0 degrees), or valgus (n = 1, 7.0 degrees) correction. Among valgus deformities, the leg axis was 6.7 +/- 2.3 degrees valgus and TT-TG 19.3 +/- 5.0 mm. We performed 12 medially closing-wedge DFOs (7.6 +/- 2.8 degrees) with MPFL augmentation (n = 12) and tibial tubercle transfer (n = 9, 11.4 +/- 7.3 mm). Visual analogue pain scale improved from 6.2 to 1.5 (p = 0.000), Kujala score from 45.0 to 81.5 (p = 0.000), Lysholm score from 40.3 to 83.9 (p = 0.000), and Tegner score from 2.1 to 3.9 (p = 0.000). Preoperative cartilage damage significantly influences the postoperative functional outcome (Lysholm score) (p = 0.026) as well as the improvement in terms of the Kujala score (p = 0.045) in the overall collective. No redislocation was observed. Patellofemoral maltracking and instability in torsional and axis deformities can successfully be treated by combined DFOs with excellent clinical results. The coexistence of risk factors for patellar instability requires a combination of additional procedures to complement the osteotomy. Preoperative cartilage lesions significantly influence the clinical outcome.

Although patients with knee osteoarthritis (OA) have shown restricted life-space mobility, total knee arthroplasty (TKA) does not improve it beyond preoperative levels. Life-space mobility after TKA was influenced by self-efficacy for walking tasks; thus, an intervention to improve self-efficacy for walking tasks may contribute to better life-space mobility. We provided a walking event including several walking tasks as the intervention. We assessed the effect of the walking event on life-space mobility and self-efficacy for walking tasks in patients following TKA. In this nonrandomized controlled trial, patients who underwent primary TKA were recruited. After recruitment, patients who could not participate in the walking event due to scheduling conflicts were included in the control group. The walking event consisted of 3.5 km of walking course and included walking tasks as follows: crossing at the crosswalk, walking up- and downstairs without a railing, walking along dirt roads, and walking up and down a slope. The primary outcome was life-space mobility measured using Life-Space Assessment (LSA) and self efficacy for walking tasks measured using the modified Gait Efficacy Scale (mGES). We enrolled 104 patients, of whom 36 were assigned to the intervention group and participated in the walking event. Participants in the intervention group had significantly better LSA score (adjusted mean difference between groups: 13.9; 95% confidence interval: 12.4-15.5; p < 0.001) and mGES score (adjusted mean difference between groups: 13.8; 95% confidence interval: 12.4 15.1; p < 0.001) than the control group even after adjusting for age, gender, body mass index, elapsed time from surgery, the severity of knee OA of nonoperated limb, and patient-reported functional outcome. The walking event including various walking tasks improved life-space mobility and self-efficacy in patients following TKA. It is important to design a program that can improve self efficacy for walking tasks through mastery experiences to improve life-space mobility after TKA. PMID- 30282101 TI - Effect of Femoral Antetorsion on Tibiofemoral Translation and Rotation in the Anterior Cruciate Ligament Deficient Knee. AB - We aimed to investigate how increased or decreased femoral antetorsion would affect the biomechanics of the knee in an anterior cruciate ligament (ACL) deficient cadaveric model. We hypothesized that external or internal rotation of the distal femur, achieved through a femoral osteotomy, would affect the magnitude of tibiofemoral translation and rotation. Navigated measurements of tibiofemoral translation and rotation during the anterior drawer, Lachman, and pivot shift tests were performed on six whole-body cadaveric specimens in each of the following four conditions: native, ACL-deficient knee, ACL-deficient knee and 20-degree internal distal femur rotation, and ACL-deficient knee and 20-degree external distal femur rotation. Increased femoral antetorsion significantly reduced anterior tibial translation in the ACL-deficient knee during the anterior drawer, Lachman, and pivot shift tests (p < 0.05). Conversely, decreasing femoral antetorsion resulted in an increase in anterior tibial translation in the anterior drawer (nonsignificant), Lachman (p < 0.05), and pivot shift (p < 0.05) tests. Internally rotating the distal femur significantly reduced the magnitude of tibial rotation during the pivot shift test in the ACL-deficient knee (p < 0.05), whereas external rotation of the distal femur significantly increased tibial rotation (p < 0.05). The magnitude of femoral antetorsion affects tibiofemoral translation in an ACL-deficient cadaveric mode. Internally rotating the distal femur 20 degrees reduced the magnitude of tibial translation and rotation similar to that of the native knee, whereas externally rotating the distal femur aggravated translational and rotational instability. PMID- 30282102 TI - Albumin, Prealbumin, and Transferrin May Be Predictive of Wound Complications following Total Knee Arthroplasty. AB - Nutritional status has become increasingly important in optimizing surgical outcomes and preventing postoperative infection and wound complications. However, currently, there is a paucity in the orthopaedics literature investigating the relationship between nutritional status and wound complications following total knee arthroplasty (TKA). Therefore, the purpose of this study was to determine the prevalence of (1) postoperative infections, (2) wound complications, (3) concomitant infection with wound (CoIW) complication, and (4) infection followed by wound complication by using (1) albumin, (2) prealbumin, and (3) transferrin levels as indicators of nutritional status. These four different outcome measures were chosen as they are encountered commonly in daily clinical practice. A retrospective review of a national private payer database for patients who underwent TKA with postoperative infections and wound complications stratified by preoperative serum albumin (normal: 3.5-5 g/dL), prealbumin (normal: 16-35 mg/dL), and transferrin levels (normal: 200-360 mg/dL) between 2007 and 2015 was conducted. Patients were identified by Current Procedural Terminology (CPT), International Classification of Disease, ninth revision (ICD-9) codes, and Logical Observation Identifiers Names and Codes (LOINC). Linear regression was performed to evaluate changes over times. Yearly rates of infection, as well as a correlation and odds ratio analysis of nutritional laboratory values to postoperative complications, were also performed. Our query returned a total of 161,625 TKAs, of which 11,047 (7%) had postoperative wound complications, 18,403 (11%) had infections, 6,296 (34%) had CoIW, and 4,877 (4%) patients with infection developed wound complications. Albumin was the most commonly ordered laboratory test when assessing complications (96%). Wound complications, infections, CoIW, and infection with wound complications after were higher in those below the normal range: albumin <3.5 g/dL (9, 14, 6, and 5%), prealbumin <15 mg/dL (20, 23, 13, and 12%), and transferrin <200 mg/dL (12, 17, 6, and 6%). Preoperative albumin, prealbumin, and transferrin values falling below the normal range represented an increased risk for postoperative complications. Those patients who were in the normal range, however, did not have an increased risk. Therefore, our results suggest that preoperative nutritional optimization can play an important role in reducing the risk for postoperative complications. PMID- 30282104 TI - Association between Gestational Weight Gain Adequacy and Adverse Maternal and Neonatal Outcomes. AB - OBJECTIVES: To estimate the prevalence of gestational weight gain (GWG) adequacy according to the 2009 guidelines, and to examine the association between GWG adequacy and the adverse outcomes, stratified by prepregnancy body mass index (BMI). STUDY DESIGN: A retrospective cohort study, using the 2011 to 2013 U.S. linked birth/infant death datasets, restricted to nonanomalous singleton live births at 37 to 41 weeks. The adverse outcomes included composite maternal morbidity (CMM), composite neonatal morbidity (CNM), and neonatal and infant mortalities. We used multivariable Poisson's regression models with robust error variance to examine the association between GWG adequacy and adverse outcomes. RESULTS: Of 8,656,791 singleton live births, 20, 32, and 48% had inadequate, adequate, and excessive GWG, respectively. After multivariable regression adjustment, compared with adequate GWG, excessive GWG had 1.10 (1.08-1.13) and 1.12 (1.10-1.14) times higher risk of CMM and CNM, respectively; similar findings were observed in BMI subgroups. Compared with adequate GWG, inadequate GWG had 1.14 (1.03-1.26) and 1.12 (1.07-1.18) times higher risk of neonatal and infant mortalities, respectively. Similar results were noted among women with normal weight. CONCLUSION: Excessive GWG was associated with an increased risk of CMM and CNM, while inadequate GWG was associated with a higher risk of neonatal and infant mortalities. PMID- 30282103 TI - Risk of Ischemic Placental Disease in Relation to Family History of Preeclampsia. AB - OBJECTIVE: To assess the risk of ischemic placental disease (IPD) including preeclampsia, small for gestational age (SGA), and abruption, in relation to preeclampsia in maternal grandmother, mother, and sister(s). STUDY DESIGN: We performed a secondary analysis of data from a randomized trial of vitamins C and E for preeclampsia prevention. Data on family history of preeclampsia were based on recall by the proband. The associations between family history of preeclampsia and the odds of IPD were evaluated from alternating logistic regressions. RESULTS: Of the 9,686 women who delivered nonmalformed, singleton live births, 17.1% had IPD. Probands provided data on preeclampsia in 55.5% (n = 5,374) on all three family members, 26.5% (n = 2,562) in mother and sister(s) only, and 11.6% (n = 1,125) in sister(s) only. The pairwise odds ratio (pOR) of IPD was 1.16 (95% confidence interval [CI]: 1.00-1.36) if one or more of the female relatives had preeclampsia. The pORs of preeclampsia were 1.54 (95% CI: 1.12-2.13) and 1.35 (95% CI: 1.03-1.77) if the proband's mother or sister(s) had a preeclamptic pregnancy, respectively, but no associations were seen for SGA infant or abruption. CONCLUSION: This study suggests that IPD may share a predisposition with preeclampsia, suggesting a familial inheritance. PMID- 30282105 TI - PaO2/FiO2 Ratio as Predictor of Mortality in Neonates with Meconium Aspiration Syndrome. AB - OBJECTIVES: Partial arterial pressure of oxygen/fraction of oxygen in inspired air (PaO2/FiO2) ratio has been used as a predictor of outcome in some neonatal conditions, but has not been used in meconium aspiration syndrome (MAS). This study was conducted with the objective to study if the PaO2/FiO2 ratio of < 200 at 6, 12, and 24 hours of life can predict mortality in neonates with MAS. STUDY DESIGN: Two hundred neonates with MAS were included in the study. PaO2/FiO2 ratio was calculated at 6, 12, and 24 hours of life. Sensitivity, specificity, predictive values, and likelihood ratio at cut-off < 200 to predict mortality was calculated. RESULTS: PaO2/FiO2 ratio at cut-off of < 200 was found to predict mortality in neonates with MAS with 94.1% sensitivity and 96.6% specificity. It was also able to predict development of severe MAS. CONCLUSION: PaO2/FiO2 at < 200 can predict all-cause mortality in neonates with MAS. It can be used as vital tool in identifying newborns at high risk, thus helping in focused care. PMID- 30282106 TI - The Role of Umbilical Cord Blood Concentration of IGF-I, IGF-II, Leptin, Adiponectin, Ghrelin, Resistin, and Visfatin in Fetal Growth. AB - OBJECTIVE: Herein, we measured the concentration of insulinlike growth factor I (IGF-I), IGF-II, leptin, adiponectin, ghrelin, resistin, and visfatin in the umbilical cord blood of newborns categorized as "small for gestational age" (SGA), "appropriate for gestational age" (AGA), and "large for gestational age" (LGA). Our aim was to elucidate the link between the levels of these proteins and fetal growth. STUDY DESIGN: A total of 96 term infants were included and categorized into three weight categories. Their venous cord blood samples were collected to measure the levels of IGF-I, IGF-II, leptin, adiponectin, ghrelin, resistin, and visfatin. RESULTS: IGF-I, visfatin, and leptin levels showed significant differences among the groups. Pairwise comparisons showed that adiponectin (p = 0.023), resistin (p = 0.025), and ghrelin (p = 0.005) levels were significantly lower in the SGA group than in the LGA group. Correlation analyses showed a strong association of IGF-1, IGF-II, and leptin levels with birth weight (r = 0.644, p < 0.001; r = 0.441, p < 0.001; and r = 0.404, p < 0.001, respectively). CONCLUSION: SGA newborns showed a significantly higher visfatin concentration and lower ghrelin, leptin, resistin, and adiponectin levels than the AGA and LGA newborns did. PMID- 30282107 TI - Time to Delivery after Scheduled Shirodkar Cerclage Removal in Singleton Gestations based on the Original Indication for Cerclage Placement. AB - OBJECTIVE: To estimate the time to delivery after elective cerclage removal and evaluate whether there is a difference based on the indication for cerclage placement. STUDY DESIGN: This was a retrospective cohort of singleton pregnancies that underwent Shirodkar cerclage placement at a single maternal fetal medicine practice between June 2005 and June 2017. We included all scheduled elective cerclage removals >36 weeks. The primary outcome was latency to delivery. We further compared time to delivery based on the original indication for cerclage. Data were analyzed using the one-way analysis of variance and chi-square test. RESULTS: A total of 143 patients met the inclusion criteria. Of these, 40.6% were history indicated, 51.0% ultrasound indicated, and 8.4% exam indicated. The mean time from removal to delivery was 13.3 +/- 8.4 days; 12.6% (18/136) of patients delivered within 24 hours of removal. When stratified by indication for cerclage, there were no significant differences for all delivery outcomes. Delaying cerclage removal to >37 weeks resulted in a statistically significantly later gestational age at delivery compared with removal between 36 and 366/7 weeks (39.0 vs. 38.3 weeks, p = 0.001). CONCLUSION: The mean time from elective Shirodkar cerclage removal to delivery is 13 days with only 12.6% of patients delivering within 24 hours of removal. PMID- 30282108 TI - Risk of Cesarean Delivery among Nulliparous Asian-Indian Women with Term Singleton Pregnancies. AB - OBJECTIVE: Asian-Indian women are a growing population in the United States, but little data exist about their risk of cesarean delivery (CD). We characterize the odds of CD among Asian-Indian women and determine whether neonatal birth weight modifies this relationship. STUDY DESIGN: This is a retrospective cohort study using an administrative perinatal database from California. We identified 1,029,940 nulliparous women with live, singleton, nonanomalous deliveries between 37 and 42 completed weeks of gestation. We performed multivariable logistic regression analyses to determine if Asian-Indian women were more likely to deliver by CD, compared with white non-Hispanic women, adjusting for sociodemographic and clinical variables. We explored if birth weight was an effect modifier, testing the interaction term's significance using Wald's test, and performed multivariable logistic regressions stratified by birth weight category. RESULTS: Asian-Indian women comprised 2.0% of the cohort. Compared with white non-Hispanic women, Asian-Indian women had an adjusted odds of 1.41 (95% confidence interval: 1.36-1.46) for CD. However, we noted effect modification of birth weight on the odds of CD by race/ethnicity (p < 0.001). Among all birth weight categories exceeding 3,000 g, Asian-Indian women had higher odds of CD than white non-Hispanic women. CONCLUSION: Asian-Indian women are at greater risk of CD than white non-Hispanic women when birthweight exceeds 3,000 g. PMID- 30282109 TI - Post-traumatic stress disorder in Stevens-Johnson syndrome and toxic epidermal necrolysis: prevalence and risk factors. A prospective study of 31 patients. AB - BACKGROUND: Epidermal necrolysis is a rare and severe cutaneous adverse reaction to drugs with long-term somatic consequences and potentially underrecognized psychological complications. OBJECTIVES: To assess the prevalence and risk factors of post-traumatic stress disorder (PTSD) in Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) in a population of adults undergoing psychiatric evaluation. METHODS: In this prospective study, we included adult patients admitted at the acute phase of SJS/TEN to our dermatology department from June 2009 to February 2013. The main objective was to assess the prevalence of PTSD at 6 months after the acute disease phase, defined by a PTSD Checklist score > 44. Secondary objectives were to investigate risk factors of PTSD in the medical history of patients and characteristics of the disease at the acute phase by the Peritraumatic Dissociative Experience Questionnaire (PDEQ) and Peritraumatic Distress Inventory (PDI) and the degree of impairment on the Sheehan Disability Scale. RESULTS: We initially included 32 of 80 patients admitted during the study period. At 6 months, seven of 30 still followed up had a PTSD Checklist score > 44, suggesting a PTSD prevalence of 23%; 23 (77%) patients had a hydroxyzine prescription at the acute phase. The main risk factors associated with PTSD at 6 months were psychological results at the acute phase. CONCLUSIONS: Despite frequent prescription of hydroxyzine at the acute phase, almost one-quarter of patients with SJS/TEN had PTSD at 6 months. A systematic psychiatric evaluation should be offered regularly for at least 1 year after the acute disease phase. PMID- 30282110 TI - Relationship between local presence and density of Aedes aegypti eggs with dengue cases: a spatial analysis approach. AB - OBJECTIVES: To analyze the relationship between the occurrence of dengue and ovitrap positivity and dengue egg density in two Amazonas municipalities (Brazil) in 2016. METHODS: We performed a case-control study using secondary data from the dengue fever surveillance system. Ovitraps distributed regularly in the urban area of two cities were used to monitor the presence of the vector. The relationship between egg positivity, egg density and the location of dengue cases was evaluated using two approaches as follows: (i) based on the result of the nearest neighbour ovitrap and (ii) based on the results of the set of ovitraps within the influence area of 300 m from the location of each case and control. RESULTS: During the study period, 229 confirmed cases of dengue fever were reported in Tabatinga and 89 cases in Itacoatiara. In this study, we found that the positivity of ovitraps was related to the occurrence of dengue in Tabatinga and Itacoatiara. An association between egg density of Ae. aegypti and dengue occurrence was also observed in Itacoatiara. The temporal lags for ovitrap positivity measurements were predominantly 15 or 30 days. A dengue association for egg density for a 15-day time lag was detected for one of the case-control approaches. CONCLUSIONS: The location of dengue cases is related to ovitrap egg positivity, while a less evident possible association may exist for egg density. This indicates that these traps could be used to improve vector control actions. PMID- 30282111 TI - Understanding the patient's experience of care in idiopathic pulmonary fibrosis.

PMID- 30282113 TI - Linkage to care and antiretroviral therapy initiation by testing modality among individuals newly diagnosed with HIV in Tanzania, 2014-2017. AB - OBJECTIVE: To measure linkage to care and antiretroviral therapy (ART) initiation among newly diagnosed individuals with HIV in a rural Tanzanian community. METHODS: We included all new HIV diagnoses of adults made between 2014 and 2017 during community- or facility-based HIV testing and counselling (HTC) in a rural ward in northwest Tanzania. Community-based HTC included population-level HIV serological testing (sero-survey), and facility-based HTC included a stationary, voluntary HTC clinic (VCT) and an antenatal clinic (ANC) offering provider initiated HTC (ANC-PITC). Cox regression models were used to compare linkage to care rates by testing modality and identify associated factors. Among those in care, we compared initial CD4 cell counts and ART initiation rates by testing modality. RESULTS: A total of 411 adults were newly diagnosed, of whom 10% (27/265 sero-survey), 18% (3/14 facility-based ANC-PITC) and 53% (68/129 facility based VCT) linked to care within 90 days. Individuals diagnosed using facility based VCT were seven times (95% CI: 4.5-11.0) more likely to link to care than those diagnosed in the sero-survey. We found no difference in linkage rates between those diagnosed using facility-based ANC-PITC and sero-survey (P = 0.26). Among individuals in care, 63% of those in the sero-survey had an initial CD4 count >350 cells/mm3 vs. 29% of those using facility-based VCT (P = 0.02). The proportion who initiated ART within 1 year of linkage to care was similar for both groups (94% sero-survey vs. 85% facility-based VCT; P = 0.16). CONCLUSIONS: Community-based sero-surveys are important for earlier diagnosis of HIV-positive individuals; however, interventions are essential to facilitate linkage to care. PMID- 30282114 TI - Multi-Objective Genetic Algorithm Assisted by an Artificial Neural Network Metamodel for Shape Optimization of a Centrifugal Blood Pump. AB - A centrifugal blood pump is a common type of the pump used as a left ventricular assist device (LVAD) in the medical industries. The reduction of the LVADs hemolysis level to reduce the blood damage is one of the major concerns in designing of such devices. Also, the enhancement of the LVADs efficiency to decrease the battery size is another design requirement. The blood damage critically depends on the state of the blood being pumped. Besides the blood state, the blood damage also depends on the pump impeller and volute geometries. In this research, a multi-objective optimization of a centrifugal blood pump is performed. A complete 3D-optimization platform is established for both impeller and volute of a centrifugal blood pump consisting of parametric modeling, automatic mesh generation, computational fluid dynamics (CFD) simulation, and optimization strategy. A vast number of cases with various impeller and volute shapes are numerically simulated. Three different metamodels are created using artificial neural networks (ANNs) in order to approximate the pump hydraulic efficiency, hemolysis index (HI), and pressure head. The inverse of the relative pressure head is defined as the first objective and the summation of relative hemolysis index and the inverse of the relative efficiency is assumed as the second objective. Non-dominated Sorting Genetic Algorithm-II (NSGA-II) is used to find the Pareto Front. A set of optimal points is selected. Finally, for the physiological flow conditions, the optimum design that provides 11.9% HI reduction and 7.2% efficiency enhancement is selected. PMID- 30282115 TI - Comparison between the traditional (1997) and revised (2009) WHO classifications of dengue disease: a retrospective study of 30 670 patients. AB - OBJECTIVE: To compare WHO's traditional (1997) and revised (2009) guidelines for dengue classification, using a large sample of patients of all ages with varying clinical conditions from a dengue-endemic area in Brazil. METHODS: We compared 30 670 laboratory-confirmed dengue cases (1998-2012) using both WHO's dengue classification guidelines. Stereotype ordinal logistic regressions were used to analyse the association between patients' demographics and signs and symptoms related to dengue infection severity, as defined in the 1997 and 2009 guidelines. We then compared the degree of agreement in dengue classification of both guidelines. RESULTS: Dengue signs and symptoms in patients were poorly correlated to disease severity as defined by both guidelines (Cramer's V test <0.2). Hypotensive shock was the exception for both classifications, presenting dependence (Z = 56.42; P < 0.001, and Z = 55.24; P < 0.001) and high agreement (Cramers's V = 1; P < 0.001, and Cramers's V = 0.97; P < 0.001) for WHO 1997 and 2009, respectively. Last, we also found substantial agreement in disease classification between both guidelines (Kendall tau-b = 0.79; P < 0.001), although 2009 guidelines were more sensitive in the detection of severe cases. CONCLUSIONS: We hope our results will inform the debate about dengue classification guidelines, particularly concerning clinical value, study comparability, and ways in which future guidelines can support the clinical management of dengue. Our results suggest that caution should be taken when using WHO guidelines to assess dengue severity to improve clinical management of patients. PMID- 30282116 TI - The contribution of respiratory microbiome analysis to a treatable traits model of care. AB - The composition of the airway microbiome in patients with chronic airway diseases, such as severe asthma, chronic obstructive pulmonary disease (COPD), bronchiectasis and cystic fibrosis (CF), has the potential to inform a precision model of clinical care. Patients with these conditions share overlapping disease characteristics, including airway inflammation and airflow limitation. The clinical management of chronic respiratory conditions is increasingly moving away from a one-size-fits-all model based on primary diagnosis, towards care targeting individual disease traits, and is particularly useful for subgroups of patients who respond poorly to conventional therapies. Respiratory microbiome analysis is an important potential contributor to such a 'treatable traits' approach, providing insight into both microbial drivers of airways disease, and the selective characteristics of the changing lower airway environment. We explore the potential to integrate respiratory microbiome analysis into a treatable traits model of clinical care and provide a practical guide to the application and clinical interpretation of respiratory microbiome analysis. PMID- 30282117 TI - Venoarterial Extracorporeal Membrane Oxygenation Increased Immune Function of Spleen and Decreased Reactive Oxygen Species During Post-Resuscitation. AB - We aimed to investigate the effect of venoarterial extracorporeal membrane oxygenation (VA-ECMO) on immune function of the spleen and reactive oxygen species (ROS) during post-resuscitation in a porcine model. After 8 min of untreated ventricular fibrillation and 6 min of basic life support, pigs were randomized into two groups: Group 1 received VA-ECMO and Group 2 received conventional cardiopulmonary resuscitation. After successful return of spontaneous circulation, the hemodynamic status was determined and blood samples were collected at 0, 1, 2, 4, and 6 h. Surviving pigs were euthanized 6 h after return of spontaneous circulation, their spleens were harvested and the T-cells were separated. Then, we investigated immune function parameters of the spleen and ROS levels. VA-ECMO increased the return of spontaneous circulation and 6 h survival rate after return of spontaneous circulation. Compared with the conventional cardiopulmonary resuscitation group, the VA-ECMO group showed increased superoxide dismutase and decreased malondialdehyde and ROS levels. Furthermore, VA-ECMO was associated with a high rate of CD4+ and CD4+/CD8+, high levels of interleukin 2, interferon gamma, and interferon gamma/interleukin 4, as well as high proliferation of lymphocytes. The apoptotic rate of T-cells was lower in the VA-ECMO group than it was in the conventional cardiopulmonary resuscitation group. VA-ECMO increased immune function of spleen and decreased ROS levels during post-resuscitation. Further research is expected to illustrate whether the differences in immune responses are due to ROS or some other perfusion related effect on spleen. PMID- 30282118 TI - Evaluating the use of a temperature sensor to monitor spectacle compliance in warm versus cold climates. AB - BACKGROUND: This study investigates the utility of a temperature sensor data logger to monitor spectacle compliance for future application in research and clinical settings. Specifically, the question of whether warm versus cold climates negatively impact accuracy of the sensor to monitor spectacle wear is investigated. METHODS: Fifty adults from Houston, Texas (summer) and 40 adults from Columbus, Ohio (winter) wore a thermosensor on their spectacles for one week while keeping wear-time logs. Temperatures during reported spectacle wear (ON) were compared to temperatures during non-wear (OFF) between sites. Two methods to approximate wear time were evaluated by percent error with respect to subject reported wear time. Method 1 filtered temperatures, classifying the range of 28.4 to 35.2 degrees C as wear. Method 2 utilised examiners interpreting temperature versus time plots. Separate analysis of periods of reported outdoor wear was performed to identify the percentage of time examiners correctly identified wear. RESULTS: Group mean ON temperatures did not differ between sites (p = 0.72), but group mean OFF temperatures were significantly warmer in Houston (Houston: 24.7 +/- 2.0 degrees C, Columbus: 20.3 +/- 2.1 degrees C; p < 0.0001). Median percent error of the filtering technique to approximate subject reported wear time was 4 per cent for Houston and -8 per cent for Columbus. Median percent error for examiner 1: Houston 1 per cent, Columbus 0 per cent; median percent error for examiner 2: Houston 3 per cent, Columbus 0 per cent. Houston outdoor wear was correctly identified 88 and 97 per cent of the time by the examiners versus 79 and 81 per cent for Columbus. CONCLUSION: Despite environmental temperature differences, measured temperatures during spectacle wear were similar across subjects and median percent error was less than 10 per cent for both wear time approximation methods. The device studied was effective for objectively monitoring spectacle wear in both warm and cold climates with the caveat that subjects spent the majority of time indoors. PMID- 30282119 TI - The relationship between the C-statistic and the accuracy of program-specific evaluations. AB - The C-statistic of the risk-adjustment model is often used to judge the accuracy of program evaluations. However, the C-statistic depends on the variability in risk for individual transplants and may be inappropriate for determining the accuracy of program evaluations. A simulation study investigated the association of the C-statistic with several metrics of program evaluation accuracy, including categorizing programs into the 5-tier system and identifying programs for regulatory review. The simulation study used data from deceased donor kidney alone transplants for adult recipients in the program-specific reports released January 2018. A range of C-statistics was generated by changing the variability in risk for individual transplants. The C-statistic had no association with any metric of program evaluation accuracy. Instead, the number of expected events at a program was the most important factor. For example, Spearman's rho, which is the correlation of ranks, was -0.27 and -0.72 between the true program-specific hazard ratios and assigned tiers for programs with, respectively, <3 and >10 expected events. Presence of unadjusted risk factors did not modify the associations, although the accuracy of program evaluations was systematically lower. Therefore, the C-statistic provides no information on the accuracy of program evaluations. PMID- 30282120 TI - Transplant tourism complicated by life-threatening New Delhi metallo-beta lactamase-1 infection. AB - Transplant tourism, which is the practice of traveling to other countries for transplant, continues to be a major problem worldwide. We describe a patient who traveled to Pakistan and underwent commercial kidney transplant. He developed life-threatening infections from New Delhi metallo-beta-lactamase-1-producing Enterobacter cloacae and Rhizopus oryzae, resulting in a necrotizing kidney allograft infection and subsequent external iliac artery rupture. He survived after a prolonged course of nonstandardized antimicrobial therapy, including a combination of aztreonam and ceftazidime-avibactam, and aggressive surgical debridement with allograft nephrectomy. The early timing of infection with these unusual organisms localized to the allograft suggests contamination and substandard care at the time of transplant. This case highlights the challenges of caring for these infections and serves as a cautionary tale for the potential complications of commercial transplant tourism. PMID- 30282121 TI - Assessment of pattern and outcomes of pesticides poisoning in a tertiary care hospital. AB - OBJECTIVES: To assess the socio-demographic profile, pattern and treatment outcomes of pesticides poisoning. METHODS: A prospective observational study was conducted at the department of emergency medicine of a South Indian tertiary care hospital for 1.5 years to study the pattern and outcomes of poisoning cases due to pesticides. Level of significance (P) <0.05 was considered as statistically significant. RESULTS: A total of 375 poisoning victims with intentional/accidental exposure to pesticides were followed up and documented. The male-female ratio was 1:0.32; mean age was 31.65 +/- 13.10 years. 72% of cases were rural residents. Organophosphorus compounds were the most implicated pesticides. Mean Glasgow Comatose Score (GCS) of the patients was 12.22 +/- 3.86. 80.3% of patients recovered while 6.4% died. About 13.3% patients were lost to follow-up as they were discharged against medical advice (DAMA). CONCLUSION: There was a statistical significance seen in the implication of pesticides for intentional poisoning with age, route of administration, area of residence and occupation of the victims. However, there was a strong association of the outcomes of poisoning with the toxic agent implicated for the poisoning. PMID- 30282122 TI - Hypothermic Machine Perfusion Versus Static Cold Storage in Deceased Donor Kidney Transplantation: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. AB - Static cold storage (SCS) and hypothermic machine perfusion (HMP) are two primary options for renal allograft preservation. Compared with SCS, HMP decreased the incidence of delayed graft function (DGF) and protected graft function. However, more evidence is still needed to prove the advantages of the HMP. In this study, the outcomes of kidney grafts from the two preservation methods were compared by conducting a systematic review and meta-analysis. Randomized controlled trials (RCTs) comparing the effect of hypothermic machine perfusion and static cold storage in deceased donor kidney transplantation were identified through searches of the MEDLINE, EMBASE, and Cochrane databases between January 1, 1980 and December 30, 2017. The primary endpoints were delayed graft function and graft survival. Secondary endpoints included primary non-function (PNF), graft renal function, duration of DGF, acute rejection, postoperative hospital stay and patient survival. Summary effects were calculated as risk ratio (RR) with 95% confidence interval (CI) or mean difference (MD) with 95% confidence intervals (CI). A total of 13 RCTs were included, including 2048 kidney transplant recipients. The results indicated that compared with SCS, HMP decreased the incidence of DGF (RR 0.78, 95% CI 0.69-0.87, P < 0.0001), and improved the graft survival at 3 years (RR 1.06, 95% CI 1.02-1.11, P = 0.009). There was no significant difference in other endpoints. HMP might be a more desirable method of preservation for kidney grafts. The long-term outcomes of kidney allografts stored by hypothermic machine perfusion still need to be further investigated. PMID- 30282123 TI - Genome-wide association study reveals new loci involved in Arabidopsis thaliana and Turnip mosaic virus (TuMV) interactions in the field. AB - The genetic architecture of plant response to viruses has often been studied in model nonnatural pathosystems under controlled conditions. There is an urgent need to elucidate the genetic architecture of the response to viruses in a natural setting. A field experiment was performed in each of two years. In total, 317 Arabidopsis thaliana accessions were inoculated with its natural Turnip mosaic virus (TuMV). The accessions were phenotyped for viral accumulation, frequency of infected plants, stem length and symptoms. Genome-wide association mapping was performed. Arabidopsis thaliana exhibits extensive natural variation in its response to TuMV in the field. The underlying genetic architecture reveals a more quantitative picture than in controlled conditions. Ten genomic regions were consistently identified across the two years. RTM3 (Restricted TEV Movement 3) is a major candidate for the response to TuMV in the field. New candidate genes include Dead box helicase 1, a Tim Barrel domain protein and the eukaryotic translation initiation factor eIF3b. To our knowledge, this study is the first to report the genetic architecture of quantitative response of A. thaliana to a naturally occurring virus in a field environment, thereby highlighting relevant candidate genes involved in plant virus interactions in nature.

PMID- 30282124 TI - Apple rootstocks of different nitrogen tolerance affect the rhizosphere bacterial community composition. AB - AIMS: To select apple rootstocks that are tolerant to low nitrogen and reveal the relationship between the rhizosphere bacterial communities and the low nitrogen tolerance of the apple rootstock. METHODS AND RESULTS: In total, 235 lines of hybrids of Malus robusta Rehd. * M.9 with low nitrogen stress were cultivated in pots in a greenhouse equipped with a drip irrigation system, and growth characteristics, photosynthesis traits and mineral elements were monitored. The bacterial community structure of the rhizosphere from different rootstocks was determined via Illumina MiSeq sequencing. This study selected three low nitrogen tolerant (NT) lines that had higher nitrogen concentration, and higher photosynthesis rate than the three low nitrogen-sensitive (NS) lines. The bacterial community structure significantly differed (P <= 0.001) among the rootstocks. The bacterial phyla Proteobacteria and Actinobacteria were the dominant groups in the rhizosphere and presented higher abundance in the NT rhizosphere. The N concentration in the apple rootstocks exhibited highly positive Pearson correlations with the bacterial genera Sphingomonas, Pseudoxanthomonas, Bacillus and Acinetobacter, and negative correlations with the bacterial genera Pseudarthrobacter and Bradyrhizobium. CONCLUSIONS: This study showed that investigated rootstocks achieved increased nitrogen concentration by enhancing their photosynthetic production capacity and shaping their rhizobacteria community structure. SIGNIFICANCE AND IMPACT OF THE STUDY: The findings provide a basis for studying the mechanisms of resistance to low nitrogen stress in apple rootstocks. Based on these beneficial bacteria, microbial inoculants can be developed for use in sustainable agricultural and horticultural production. PMID- 30282126 TI - African-American Women's Perceived Risk for Cardiovascular Disease versus Framingham Risk. AB - Cardiovascular disease (CVD) is the leading cause of death among African-American women in the United States. Accurate CVD risk perception may motivate these women to participate in health-promoting behaviors; however, perceived risk may not align with objective CVD risk. Our objective was to examine CVD risk perception, risk factors, and objective estimated risk (based on Framingham scores). This was a secondary data analysis of data collected from a 12-month lifestyle PA intervention conducted with 281 African-American women. Subjective perceived CVD risk was measured with two questions; CVD risks were examined via health assessment and self-questionnaire; and objective estimated CVD risk was calculated using the Framingham Risk score. Despite having several objective risk factors for CVD development, most participants perceived their CVD risk as low, and their Framingham scores were low. The Framingham Risk score may not be the best predictor of CVD risk for African-American women. PMID- 30282127 TI - Promoting Self-Management of Hypertension in the African-American Church. AB - Hypertension (HTN) continues to be one of the most preventable diseases that have global impact. The prevalence of HTN in African-Americans is considered to be among the highest in the world. This investigation sought to determine whether a church-based self-management program would aid African-American adults (18 years of age and above) in reducing their blood pressure (BP). The theoretical foundation was the Health Belief Model. The clinical question was: Will a church based American Heart Association (AHA) program on BP self-management decrease BP in African-American adults (aged 18 and above) who belong to a local Christian church? The quantitative methodology and pretest-posttest single group design were used in this investigation. The sample was a convenience sampling of 23 Christian church members. The participants enrolled in the AHA's "Check. Change. Control(r). Tracker." There were only two demographic variables that were significant at the 0.05 level (2-tailed) with the initial BP: age was 0.585 (p = 0.05) and having children was -0.434 (p = 0.039). The paired t-test was computed for the initial and final systolic BPs. The paired t-test for these variables was 1.844 (p = 0.079). The paired t-test was computed for the initial and final diastolic BPs. The paired t-test for these variables was 1.724 (p = 0.079). These results indicated there were no improvements after the intervention. However, data supported clinical significance. PMID- 30282128 TI - Evaluating Relevance of Nursing Theories in Cross-Cultural and International Contexts. AB - Nursing has evolved over the past five decades in propagating the development of theoretical and empirical evidence through the application of nursing theories. The objective of this commentary is to stimulate scholarly debate focused on the development, application, and adaptation of nursing theory by nurse scientists, its relevance in the cross-cultural contexts, and to discuss future directions with a call to action using Leininger's seminal work on Culture Care Theory. The implicit nature of nursing theories preclude the optimal use and application in cross- cultural contexts because of the limitations in achieving conceptual, semantic, and operational equivalence. Work conducted by nurse scientists to date demonstrates that cultural values and beliefs are integral in cross-cultural contexts to enhance meaningful theory application for health interventions. More work is needed to advance nursing science through cross-cultural application of theories in research, practice, and education to optimize nursing theory adaptation in cross-cultural and international contexts. PMID- 30282129 TI - Using Case Study Methodology to Explore the Role of Discrimination in Workplace Incivility. AB - Exclusionary behaviors can be detrimental to the health and well-being of faculty in the workplace. When colleagues are judged by their peers because of the color of their skin, the language they speak, their gender, or who they choose to love (lesbian, gay, bisexual, transgender, asexual, or questioning), affected faculty are left emotionally and physically vulnerable. Institutions of higher learning must set standards of zero tolerance for faculty-to-faculty incivility. With standards taken from each faculty discipline, codes of conduct can be implemented not only at a departmental level, but also throughout the educational system. PMID- 30282130 TI - The Simultaneous Experiences of Being a Nurse Faculty Member and PhD Student: A Phenomenological Inquiry. AB - The demand for nursing faculty with doctoral degrees has prompted universities to devise strategies to hasten doctoral preparation. Insufficient preparation of nursing faculty negatively impacted the ability of colleges of nursing to enroll qualified applicants. In 2011, 75,000 applicants were turned away (AACN, 2012). Interview data from 11 participants were analyzed for themes and structure of meanings that led to a description of the essence of the phenomenon. Six related themes revealed the experiences of simultaneously being a nurse faculty member and PhD student. Starck's (2004) Middle Range Theory of Meaning provided a framework for gaining a deeper understanding of this phenomenon. The findings revealed the obstacles, sacrifices, pain, and rewards of being a nurse faculty member and PhD student simultaneously. The participants embraced numerous positive aspects including personal and professional growth. Therefore, understanding this experience is fundamental in eliciting support for the journey towards a PhD. PMID- 30282131 TI - How to Create a Telephone Follow-Up Program to Improve Glycemic Control in Uncontrolled Type 2 Diabetic African-American Women. AB - Type 2 diabetes is the seventh leading cause of death in the United States and this disease disproportionately affects African-Americans and other minorities. Diabetes self-management education has been shown through research to help patients achieve at-goal HgbA1c levels leading to a decrease in complications; however, patients do not attend these classes as much as they should. The creation of a telephone follow-up plan can be an option to improve glycemic control for the primary care clinician caring for uncontrolled Type 2 diabetic African-American females. The culturally sensitive content in the follow-up plan should focus on better nutrition management, increasing physical activity, and consistent glucose monitoring with increased skill in management of results. This telephone follow-up program is intended to help clinicians assist this population of patients to identify potential barriers using culturally sensitive content as a method of connecting with patients to help them achieve at-goal HgbA1c levels. PMID- 30282132 TI - The Growing Impact of Legionella in the Flint Water Crisis. AB - The water crisis in Flint, Michigan raised national awareness about lead- tainted drinking water, particularly its harm to children and pregnant and lactating women. However, according to recent findings, there may be another by-product of this man-made crisis. Failure to use anticorrosive material in the water, a practice mandated by the 1978 Clean Water Act, is being linked to an outbreak of Legionnaires' disease, an illness detrimental primarily to adults over 65 years of age. While Legionnaires' disease is relatively rare, it is also likely to remain undiagnosed. Clinicians, therefore, are urged to consider this diagnosis in adults with pneumonia that does not respond to typical antibiotic treatment, and in newborns with respiratory distress along with other non-typical symptoms as well as those who have had water births or who were exposed to ultrasonic, cool-mist humidification.

AB - Physical inactivity can have major implications for cardiovascular disease and diabetes, which are leading causes of morbidity among African-American women. Recruiting in rural populations can present challenges and strategies that work in one community but may not be successful in another community. This study examined the feasibility, acceptability, and implementation of community-based screening using an abbreviated Racial and Ethnic Approaches to Community Health (REACH) Risk Factor self-report survey in a geographic region where these data were previously unavailable. Participants (N = 32) included African American/Black women, 21 years of age or older, who attended health screening events in a rural county in South Carolina. Findings from this study demonstrated the feasibility of community-based cardiometabolic risk screenings using an abbreviated REACH Risk Factor survey and linking participants to follow-up primary care. Findings also provide insight into recruitment strategies in this geographic region. PMID- 30282135 TI - Beauty for Ashes: A Church-Based Diabetes Care Program. AB - The pilot study described here was a test of interventions designed to enhance long-term disease management of African-Americans with type 2 diabetes in faith based organizations. A quasi-experimental design based on 46 participants was used comparing three interventions: guided imagery, group counseling, and routine care. Unexpectedly, the number of self-reported hypoglycemic episodes significantly increased in the Rational Emotive Behavioral Therapy (REBT) group, depressive symptoms significantly increased in the guided imagery group, and the mean hemoglobin A1c values did not significantly differ for any group. In future research, the authors will incorporate an interim step investigating the theory of integration (Hernandez, Antone, & Cornelius, 1999) to increase the explanatory power in assessing treatment effects of African-Americans in faith-based organizations. PMID- 30282136 TI - Being African-American, Obese, Female, and Residing in an Urban Area: The Lived Experience. AB - The objective of this qualitative study was to explore the experience of being African-American, obese, female, and residing in an urban area. Critical Social Theory of Black Feminist Thought guided the study framework and study questions. Within this framework, African-American women are multidimensional human beings with attitudes, habits, and personalities influenced by their religious beliefs, family, school, friends, and racial history. Interview data were obtained from 10 women and analyzed using qualitative techniques. These individuals were aware of health consequences related to obesity and described barriers that inhibit healthy choices. Participant level of education provided the ability to avoid negative physical and social consequences associated with obesity. PMID- 30282137 TI - The Lived Experience of African-American Informal Caregivers of Family Members with Alzheimer's Disease and Related Dementias. AB - The purpose of this qualitative study was to describe the lived experience of African-American informal caregivers of family members with Alzheimer's Disease and Related Dementias (ADRD) in a home environment. Using a qualitative, phenomenological approach, a purposive sample of 16 African-American informal caregivers completed an in-depth interview that lasted from 30 to 60 minutes. Four themes emerged: (a) a sense of obligation, (b) an arduous journey, (c) sentinel events, and (d) faith in God. Findings indicated that caregivers needed to be well-informed concerning the demands of caregiving and needed more assistance with the task of delivering care. Informal caregivers lacked support, knowledge, and guidance. Implications for the discipline of nursing include emphasis on family assessment, teaching, awareness of resources, and collaboration with healthcare teams. PMID- 30282138 TI - The Root of Physical Inactivity Among African-American Women: Identifying Exercise Friendly Hairstyles. AB - The purpose of this study was to provide information regarding hair maintenance that would increase physical activity among African-American women. A descriptive study design was used, along with Survey Monkey to obtain online responses from African-American female participants over the age of 18 that were associated with four predominately African-American social organizations. Participants were asked to rate the "ease of use" of 8 hairstyles commonly worn by Black or African American women living in the United States as it related to three physical activity (PA) intensity categories: light to moderate, vigorous, and water-based physical activity. The results revealed that short natural styles had low maintenance scores for all three PA categories (1.19, 1.27, and 1.34, respectively). Increased knowledge and understanding of the complex and varied hair care practices common among African-American women will improve development of exercise-based health interventions for this population. PMID- 30282139 TI - Exploring Older Adults' Perceptions of the Utility and Ease of Use of Personal Emergency Response Systems. AB - The aim of this exploratory-descriptive study was to explore and describe perceptions of the utility and ease of use of personal emergency response systems (PERS) among older adults who are aging in place. This study explored the question of "What is the meaning of a PERS use for a functionally-impaired older adult?" Using an exploratory-descriptive qualitative design, 14 subjects were recruited in Queens, NY, who met the study's eligibility through the selection criteria. A 9-question in-person interview guide was used to conduct the face-to face, audio-taped, semi-structured interviews in an effort to gather information on the participants' experiences with using a PERS. Data were collected over a 2 month period. While many participants admitted that they did not wear the PERS neck pendant or wrist device consistently, they still reported benefiting from having the button and participating in the program. Findings were consistent with the existing literature about compliance with PERS, that is wearing and using the device. Findings from this study suggested that PERS use is a reassuring presence, is simple and effortless, if you need it, and alone, but connected. The overarching theme is PERS is an adjunctive resource that it is a helpful backup and that promotes interconnectedness. PMID- 30282140 TI - Black Student Participation Rates Also a Concern for Educational Program Assessments. AB - Lower participation rates in the African-American population are not limited to medical research. Extant research reveals African-American students also participate at lower rates than other racial groups on college and university surveys. Students in medical and health professions programs are routinely surveyed to investigate students' perspectives about the educational curriculum, social and cultural environment, quality of faculty and resources, etc. The results attained from these assessments often carry some of the greatest weight in guiding educational curricula, programs, and policy. Thus, perhaps nowhere is there greater opportunity for African-American students to effect change than educational program assessments, where results will affect not only current and future students, but may also help improve professional development opportunities to address health disparities among minority populations. Implications and recommendations for faculty, administrators, and students in medical and health training programs are discussed. PMID- 30282141 TI - [Classification of sudden deafness prognosis based on deep learning method]. AB - Objective:This study aimed to develop predictive models for sudden sensorineural hearing loss through deep belief network (DBN) and explore whether the model performances differ when adopting different outcome criteria. Method: 228 potential predictors involving the clinical characteristics, audio logical data, and serological parameters out of 1 220 hospitalized SSHL patients who were admitted from June 2008 to December 2015 were analyzed retrospectively. The hearing data of sudden deafness were classified into two or four categories based on Chinese criteria and Siegel criteria, which were used to develop the DBN models. The area under the receiver operating characteristic curve (ROC-?AUC) and accuracy were used to compare the predictive performance of different models. Result: The DBN model developed for predicting the dichotomized outcomes had better performance than that of the four?category outcomes. When the iteration number reached 500 times, DBN model constructed for prediction of dichotomized outcomes based on Siegel's criteria had demonstrated the best performance with an accuracy of 76.25% and an AUC of 0.81. According to indices from first layer weights, DBN gave a rank of top 10 sensitive features for hearing outcome prediction focusing on indicators regarding coagulation, demographics and pre treatment hearing levels independent of the outcome assessment criteria. Conclusion: DBN provides a robust outcome prediction ability in SSHL datasets with rich and complex variables, especially when utilized to predict dichotomized outcomes based on the Siegel criteria. In addition, this advanced deep learning technique can automatically extract valuable predictors, which is consistent with those that had been verified in previous studies by traditional statistical methods. This study provides further evidence for extending the use of DBN algorithm to the field of developing prediction or classification models for other otological diseases in the future.?. PMID- 30282142 TI - [Clinical comparative study of caloric test with water or air in healthyindividuals and diagnosing study on air caloric test]. AB - Objective:To explore the equivalence of the test results of the water or air caloric tests and the compliance of the test in the healthy individuals. To provide scientific basis for clinical standardization of caloric test.Method: Randomized crossover clinical trial, 60 healthy individuals were divided into group A and group B. Water caloric test was carried out first in group A, and air caloric test was carried out after elution effect(one day interval). The treatment of group B was opposite to group A. SPV(Slow Phase Velocity), CP(canal paralysis) and SPV and CP' s 95%CI were used as evaluation indexes to analyze the equivalence of water and air caloric test in healthy people and the clinical normal reference value and stability and compliance of the water and air caloric test. Result: 160 cases of caloric test CP value of chi square test suggested that there was no statistical difference between two kinds of media in the examination of the vestibular function of healthy individuals, and the CP value of the two was 85%(51/60). 2the SPV value of the was obviously higher than that of the air caloric test. The SPV value at each temperature of the water caloric test stimulation is quite different from the air caloric test stimulation. 3The range of water caloric test stimulation CP 95%CI was 8%-12%, and the average value was 10%. The interval of air caloric test stimulation CP 95%CI was 10%-15% and the average value was 12%. 4This study provided the corresponding SPV 95%CI as the medical reference values. 5The subjects of 98.33%(59/60) of the questionnaire survey selecting air caloric test and the results of the observation indicated that the duration of the air caloric test was shorter and more comfortable. Conclusion: 1Air caloric test can satisfied the needs of clinical assessment of horizontal semicircular canal function, and can make patients feel more comfortable. However, due to the weak intensity of nystagmus, water caloric test has to be used when the SPV value is too low. 2In this study, the upper limit of the CP value of the air caloric test in healthy individuals was 0.21, which is quite different from the upper limit of the standard value was 0.25 of the water caloric test. Therefore, the laboratory should establish their own reference value of the laboratory caloric test, and should not blindly apply the standard value of the water caloric test as the standard of the hemiplegia of the unilateral semicircular canal. The results of this study suggest that air caloric test can be used instead of water caloric test in clinic. And if the patient has no contraindications, air caloric test can be used as a priority. PMID- 30282143 TI - [Study on the characteristics and clinical significance of relief of nystagmus during the restoration of benign paroxysmal positional vertigo with posterior semicircular canal]. AB - Objective:The features and parameters of the relief of nystagmus during the restoration of benign paroxysmal positional vertigo(PC-BPPV) in the posterior semicircular canal were observed to explore its clinical significance and mechanism.Method: Sixty-eight patients with PC-BPPV were treated with the Epley method. According to the subject' nystagmus relief was present or not, they were divided into two groups: group A showed relief of nystagmus during the restoration process, and group B showed no relief of nystagmus during the restoration. The effect of restoration between group A and group B was compared, and the parameters of nystagmus between the detached nystagmus and the Hallpike position in group A patients with detachable nystagmus were compared. Result: Of the 68 patients with PC-BPPV, 33(48.5%) experienced detachment of nystagmus in the same direction as the initial nystagmus(Group A) during the restoration; 35(51.5%) patients had no nystagmus during the restoration(Group B). After the instrument was reset for 2 h, Dix-Hallpike test was performed again. The success rate of reset was 100% in group A,and that was 57% in group B(20 cases were successfully repositioned, and 15 cases showed typical nystagmus). The success rate of reset was statistically different between groups A and B(P<0.01). After one week of resetting, the telephone follow-up was carried out. The recovery rate of group A and group B were 93% and 74% separately.The recovery rates between group A and B were statistically different(P<0.05). In group A, the nystagmus latency at Hallpike was(2.63+/-2.17) s, and the duration was(17.27+/-5.94) s. The rate of nystagmus in the upper leaping eye was(16.19+/-9.54) degrees /s. The latency of liberation was(2.30+/-1.41) s and the duration was(11.84+/-5.98) s. In seconds, the slow phase phasic velocity of the nystagmus was(7.80+/-4.57) degrees /s; there was no statistical difference in latency between the detached nystagmus and the Hallpike nystagmus(P>0.05), while there was a statistically significant difference between the duration and the nystagmus intensity(P<0.01).Conclusion:For PC-BPPV restoration, the presence or absence of nystagmus can be used as a reference to judge whether the restoration succeed or not.The latency of nystagmus at the Hallpike position may be related to the stalactite precipitation rate. The duration and the slow phase angle velocity of the upper hop eye may be related to the otolith quantity. PMID- 30282144 TI - [Therapeutic effects of postauricularinjection of lidocaine in tinnitus]. AB - : Objective:To observe clinical efficacy of postauricular injection of lidocaine for subjective tinnitus and explore the clinical effective method in the treatment of tinnitus. METHOD: Eighty patients with tinnitus as their first complaint were included in our study. They were randomly divided into four groups, each with 20 cases.They were treated with oral ginaton and mecobalamin tablets,and at the same time with postauricular injection of lidocaine at different doses (Group A, 2% lidocaine 3 ml; Group B, 2% lidocaine 2 ml+physiological saline 1 ml;Group C, 2% lidocaine 1 ml+physiological saline 2 ml; Group D, physiological saline 3 ml). TEQ scores were evaluated and compared before treatment, at the end of treatment, and one month after treatment.Result:At the end of treatment, the clinical effiCIency rates of four groups were 80%,70%,65% and 25% respectively. One month after treatment, the clinical effiCIency rates of four groups were 80%, 55%, 45% and 0% respectively. There were significant differences among four groups by chi square test (P<0.05).Patients' TEQ scores of the four groups after treatment were analyzed and compared by one-way ANOVA. TEQ scores of Group A,B and C were lower than Group D(P<0.05). TEQ scores of Group A were lower than Group C(P<0.05).TEQ scores at the end of treatment and one month after treatment were analyzed by paired t test. Group B and C had higher TEQ scores one month after treatment(P<0.05).The total effective rate at the end of treatment for acute, subacute and chronic tinnitus patients was 79.31%, 70.83% and 42.86% respectively. The total effective rate of one month after treatment was 75.86%, 45.83% and 42.86%, respectively. The results of chi square test showed that the total effective rate of acute tinnitus patients was significantly higher than that of subacute and chronic tinnitus in one month after treatment (P<0.05). CONCLUSION: Postauricular injection of lidocaine is effective for simple subjective tinnitus, and the dose and concentration of lidocaine affect the efficacy and durability. Postauricular injection of lidocaine for the treatment of subjective tinnitus is a therapeutic method worthy of further research and popularization.

Therefore, this article summarized the parts of clinical manifestations, pathogenesis, diagnostic criteria, treatment and prevention of vestibular migraine. PMID- 30282146 TI - [Progress in diagnosis and treatment of unilateralsensorineural hearing loss in children]. AB - Unilateral sensorineural hearing loss (USNHL) in children have traditionally been underappreciated, so we reviewed the recent researches about USNHL in children to understand their effect on development and the underlying pathophysiologic mechanisms. Early diagnosis and treatment of USNHL have a positive effect on verbal cognitive, linguistic, communicative, and socio-emotional development, as demonstrated by neurophysiological studies. And the audiological management of hearing loss should be placed within a comprehensive rehabilitative approach. Among the treatment modalities with differing effects on the quality of binaural hearing, cochlear implants are now used increasingly in children with severe-to profound USNHL. But the long-term effect and indication selection still need further study. PMID- 30282147 TI - [Demographic characteristics and canalith repositioning efficacy in 907 patients with typical benign paroxysmal positional vertigo]. AB - AbstractObjective:To review the demographic characteristics and canalith repositioning efficacy in 907 patients with typical benign paroxysmal positional vertigo(BPPV). Method: The demographic characteristics of 907 patients with typical BPPV were statistically analyzed. According to the type of BPPV, patients were treated with the appropriate repositioning maneuver, and the clinical efficacy of repositioning maneuver was analyzed and summarized. Result: Nine hundred and seven patients of BPPV with typical nystagmus were elected in this study. 585 out of 907 were female and 322 out of were male, and the mean age was 53.10+/-14.25(13 to 89) years. The lesion located to the posterior semiCIrcular canal was 489 patients(53.9%), horizontal semiCIrcular canal was 312 patients(34.4%), anterior semiCIrcular was 63 patients(6.9%), and multiple semiCIrcular was 43 patients(4.8%). According to Kaplan-Meier survival analysis curve, the median cure time for the modified Semont and Epley repositioning maneuver in PC-BPPV groups was 3 days, and there was no significant difference in survival curves between the two repositioning maneuver. Meanwhile, the median cure time for Barbecue and Li horizontal canal quick repositioning maneuver groups was 3 days, and 1 day for Gufoni repositioning maneuver group in HC-BPPV groups. And there was no significant difference in survival curves among the three repositioning maneuver. In the AC-BPPV, 7 cases, 31 cases, 57 cases, 58 cases were cured with the Li anterior canal quick repositioning maneuver in the 1st day, the 3rd day, 1 week later, and 1 month later, and 5 cases lost to be follow-up. According to Kaplan-Meier survival analysis curve, the median cure time for the Li anterior canal quick repositioning maneuver in AC-BPPV groups was 3 days. Conclusion:Repositioning maneuver represents a simple, safe, rapid and effective approach to the treatment of BPPV. Therefore, repositioning maneuver should be choice for the BPPV treatment. PMID- 30282148 TI - [Analysis of neurobehavioral function of school-aged children with sleep disordered breathing]. AB - Objective: To investigate the neurobehavioral function(attention, executive skills, behavior) of school-aged with varying degrees of SDB and control children with no history of SDB recruited from the community.Method: One hundred and sixty three children aged from 7 to 12 were enrolled in the study. Children were devided into 4 groups through the data of Routine overnight polysomnography(PSG): PS(n=71) group, mild OSAHS (n=29) group, moderate/severe OSAHS(n=21) group, and controls(n=42) group. The Behavior Rating Inventory of Executive Function(BRIEF) and the Child Behavior Checklist(CBCL) were used to assess attention, executive function and behavioral function. Result: There was significant difference of AHI, OAI, RAI, SAI and SpO 2 nadir between the mild/MS groups and the control/PS groups(F=1174.3, 1178.0, 2348.3, 34.7, 377.7, P<0.05). Total sleep time(TST) of the MS OSAHS group was significantly less than that in the control group(F=178.8, P<0.05). Increased rates of behavioral executive dysfunction were found depending on the SDB spectrum(F=181.2, 274.2, 284.5, P<0.05). Children with all severities of SDB had signicantly higher rates of total, internalizing and externalizing behavioral problems compared to control group(F=361.7, 168.3, 564.0, P<0.05). Conclusion:Our study suggests that behavioral, attention, and executive function difficulties are present in children with PS as well as OSAHS. These results have implications for the treatment of milder forms of SDB, particularly PS, which is commonly viewed as benign.

AB - Objective: To study the effect of amazing ear correction system on 2-6 months old infants with congenital ear deformity. Method: Thirty infants (37 ears) with congenital auricular deformities were enrolled in the study. Deformities included constriction, cryptopia, helicalrim, prominent, conchal strut, and Stahl deformities and microtia. The patients were divided into 2 groups. Infants elder than 2 months were 20 cases(26 auricular malformed ears). And infants under 2 months old were 10 cases(11 auricular malformed ears). All the patients underwent ear molding using the amazing ears correction system. The patients of each group were followed-up for at least 3 months. Result: The results were divided into three levels(excellent, good, and poor) according to the correction of auricular shape. In Group elder than 2 months, 13 ears were excellent and the average treatment time was 46.85 days,5 ears were good, the average treatment time was 43.40 days and 8 ears were poor, the average treatment time was 13.13 days. In Group under 2 months old, 5 ears were excellent and the average treatment time was 28.80 days,6 ears were good and the average treatment time was 18.66 days. The patients of each group were followed-up for at least 3 months and no rebound occurred. Conclusion:Ear correction system has a significant effect on those more than 2 months and less than 6 months with congenital auricular deformity. The children who were more than 2 months old need to wear the auricle appliance over 6 weeks to achieve a satisfactory effect.

Method: Forty-four OSA children diagnosed with overnight polysomnography were selected as the research object, 35 cases of pediatric no snoring healthy children were as control. The inventory of subjective life quality and children's self-rating anxiety scale were used to assess children' s life quality. Result: Depending on the data of the inventory of subjective life quality questionnaire, each level and dimension of children' s life quality satisfaction scores in OSA group were significantly lower than that in healthy controls(P<0.05), especially in the cognitive component of school life(3.78+/ 1.73) and the affective component of depression experience(3.70+/-2.18). The score of anxiety disorder in OSA group (21.39+/-10.49) was higher than that in healthy control group(14.21+/-9.69)( P<0.05). The rate of anxiety disorder in OSA group was higher than that in healthy control group(P<0.05). Conclusion:Children in OSA group had higher incidence of unsatisfactory life quality in all levels and dimensions. OSA group children dissatisfied with the life quality in each level, each dimensions have significant statistical difference, especially in the cognitive component of school life and affective components of depression experience. The OSA group had higher anxiety disorders than healthy ones. PMID- 30282154 TI - [Risk factors analysis for recurrence of the idiopathic benign paroxysmal positional vertigo]. AB - Objective:To study the risk factors of recurrence in patients with benign paroxysmal positional vertigo(BPPV) after successful repositioning treatment. Method: Two hundred and two cases of confirmed BPPV patients, were followed-up for 10 months after particle repositioning, and the incidence of recurrence was analyzed. The risk factors for recurrence were analyzed by logistic regression. Result: 51 out of 202 confirmed BPPV patients complained of recurrence. There was significant difference of the duration of vertigo before treatment, the times of repositioning and SDS between the two group(P<0.05). While the sex, the age, the incubation period of BPPV, the duration time of BPPV, underlying diseases and the type of canal were not associated with the residual dizziness(P>0.05). Logistic regression analysis showed that the times of repositioning and the SDS were the risk factor for residual dizziness. Conclusion:The effective repositioning and the psychological care are very important to reduce the recurrence of BPPV.

AB - Thyroid cancer is a common malignancy derived from the endocrine system and the incidence of thyroid cancer is on the rise. Papillary thyroid carcinoma (PTC) is the most common type, and 90% of PTC patients have long-term survival, but the recurrence rate is still as high as 30%. Current diagnostic and postoperative monitoring techniques have been developed, but their negative rates and interfering factors also occupy an absolute proportion, and lack specific markers for the prognosis of PTC. Studies have shown that microRNAs (miRNAs) are associated with the development, metastasis and invasiveness of PTC and as a biomarker to aid in the diagnosis and monitoring of recurrence, and to determine the prognosis for specific markers. The future of PTC diagnosis, treatment and improve prognosis has broad prospects. This review mainly describes the development of miRNA as biomarkers for the diagnosis, recurrence and prognosis of PTC. PMID- 30282160 TI - [Diagnosis and treatment of eosinophilic rhinosinusitis]. AB - Chronic rhinosinusitis (CRS), a chronic inflammation of the nasal sinus mucosa, is based on a simplified classification of a single clinical phenotype (with or without nasal polyps) that does not adequately reflect the heterogeneity of the pathogenesis of chronic rhinosinusitis complexity. Currently, according to the lesion mucosa or polyps eosinophil infiltration,this type of chronic rhinosinusit is known as eosinophilic chronic rhinosinusitis (ECRS). The curative effect of ECRS is poor than non-eosinophilic rhinosinusitis. This article summarizing the diagnosis and treatment of eosinophilic rhinosinusitis status, is to provide help for clinical diagnosis and treatment.

Pathogenic mutations have been discovered in several genes such as EYA1, SIX5, and SIX1. However, it has a high penetrance with variable expressivity. The clinical and genetical heterogeneity is widespread amongst and within families. In this review, we describe the clinical manifestations and pathogenic genes with copy number variations in detail, and emphasize the criteria clinically and genetically to provide the basis for clinical diagnosis of BOR and genetic counseling. PMID- 30282166 TI - [X-linked Alport syndrome: auditory pathogenic variant features and further genotype-phenotype correlations in female patients]. AB - Objective:To analyze the audiological characteristics of female patients with X linked Alport syndrome and to explore the relationship between genotype and phenotype in China. Method:The hearing data of 64 females diagnosed as Alport syndrome was reviewed and analyzed. All coding exons of COL4A5 genes were PCR amplified and sequenced with genomic DNA, or mRNA of COL4A5 gene was RT-PCR amplified and sequenced with skin fibroblast. Result:The 64 cases who were accompanied by hematuria or proteinuria all received pure tone audiometry and acoustic immitance test. The incidence of hearing loss was 20.31% (13/64). The hearing were bilaterally symmetrical sensorineural deafness, most of which were mild and moderate hearing loss. The hearing curve is the groove curve. Among the 64 patients, 42 kinds of DNA variants were detected in 52 cases. Among the patients with hearing loss, 1 of them was 12 years old and the rest were over 35 years old. Mild mutations in 13 cases (10 cases of normal hearing and 3 cases of mild hearing loss) and severe mutations in in 12 cases ( 6 cases of normal hearing and 6 cases of mild to moderate hearing loss) were found in 25 cases over 35 years old. A total of 26 cases were followed up for 2 years or more, of which 7 cases had a downward trend of hearing loss, decreased about 5 dB each year, and there was no significant change in the hearing of the other patients. Conclusion:Mild and moderate hearing impairment, and groove type of audiometric curve are mainly found in Chinese X-linked Alport syndrome in females. Hearing loss occurs at middle-age. The onset time of hearing loss was later than that of the male, and the severity of hearing loss was lighter than that of the male. In the course of follow-up, some patients had a downward trend in hearing, and there was no significant correlation between the hearing phenotype and the genotype. PMID- 30282167 TI - [Cochlear implantation and early outcomes in children with incompletely partition type III malformation]. AB - Objective:To analyze the early effect of the cochlear implantation (CI) in children with cochlear incompletely partition type III malformation (IP-III). Method:Ten children with IP-III malformation who underwent CI were recruited in this study. The hearing characteristics, preoperative speech performance and surgery were analyzed retrospectively. The aided hearing threshold with CI, the categories of auditory performance (CAP) score, speech intelligibility rating (SIR) score and speech perception were designed to access the benefits of CI. Ten children with normal cochlea were also enrolled as the control group. Demographic information of children in the control group including hearing loss and speech level before implantation, age at implantation, hearing aids using history, duration with CI were matched with those in the IP-III group. The hearing threshold, CAP score and SIR score in the IP-III group were compared with the control group using the SPSS 20.0 software. Result:The computed tomography of temporal bones showed typical IP-III malformation in all patients. The electrode arrays were properly and totally implanted in all children. Cerebrospinal fluid gusher occurred intra-operatively, and no other complications in all patients. The pure tone average (PTA) threshold at the 3rd, 6th, 9th and 12th month after implantation were (40.8+/-8.5) dB HL, (36.1+/-9.1) dB HL, (32.5+/-6.8) dB HL and (33.0+/-7.3) dB HL, respectively. The PTA thresholds in the IP-III group were similar to those in the control group at all tested time points (P>0.05). At the 3rd, 6th, 9th and 12th month after implantation, the CAP scores in the IP-III group were lower than those in the control group, but there was no significantly difference (P>0.05). Furthermore, the SIR scores were lower than those in the control group, and there were significantly difference at the 6 th, 9 th and 12 th month after implantation (P<0.05). Conclusion:CI was an effective treatment for children with IP-III malformation. Surgery on IP-III was challenging, however, seldom complication would occur with excellent surgical skills. Though the CI was benefit for IP-III, the development of hearing and speech ability were slower than children with normal cochlea. PMID- 30282168 TI - [Goldenhar syndrome].

AB - Objective:To investigate the clinical application value and related technology of modified cosmetic incision and cyanoacrylate octyl ester skin adhesive (Dermabond) in functional surgery of parotid benign tumor. Method:Forty-two cases of clinical cases were collected and randomly divided into groups of A and B. Group A used the approach of modified cosmetic incision,intradermal suture with 6 0 absorbable Vicryl stitches and gluing the skin with Dermabond. Group B used the approach of traditional S shaped incision and continuous suture of skin with 4-0 Prolene stitches.The operative time, postoperative drainage volume, facial nerve function, salivary leakage, Frey syndrome, postoperative numbness, scar and aesthetic satisfaction were compared between the two groups. Result:The operation time, facial nerve function,Frey syndrome, salivary fistula, facial deformity and tumor recurrence in the two groups had no significant difference (P>0.05); but for postoperative drainage, postoperative numbness, facial appearance satisfaction, scar assessment, Group A was lower than Group B and there was statistical significance difference (P<0.05). Conclusion:The application of modified cosmetic incision and Dermond is safe and feasible. Its complication is lower than the traditional operation. The scar is smaller and more hidden, and the patient's satisfaction is higher. It doesn't affect the daily social interaction of patients, and achieves the effect of minimally invasive treatment. PMID- 30282172 TI - [Association between the morphological classification and prognosis of conservative treatment for vocal fold leukoplakia]. AB - Objective:To explore the association between the morphological classification and prognosis of conservative treatment for vocal fold leukoplakia. Method:Patients with different types of vocal fold leukoplakia received conservative treatment first. Those who had failed response to conservative treatment or recurred received carbon dioxide laser resection. Then the efficacy and recurrence rate were compared among the three types of vocal fold leukoplakia. Result:Two hundred and thirty-six patients consisted of 78 flat and smooth cases, 146 bulge and smooth cases, and 12 rough cases. The complete response rate of conservative treatment for the three types was 80.8%, 65.1%, and 0%, respectively (P<0.01). Out of 158 patients who had complete response to conservative treatment, 10.1% cases recurred in 1 year (flat and smooth vs. bulge and smooth, 6.3% vs. 12.6%,P=0.283). Totally, 78 patients had no complete response to conservative treatment and 16 patients experienced recurrence, whose complete response rate of carbon dioxide resection was 89.5%, 85.7%, and 75.0%, respectively (P=0.53). The pathological results were significantly different among three types. The complete response rate of conservative treatment combined with surgery for three types was 97.4%, 93.8%, and 75.0%, respectively, and the complete response rate of flat and smooth type was significantly higher than that of rough type (P=0.002). Conclusion:The Conservative treatment could be based on the morphological classification of vocal fold leukoplakia. The treatment modality that conservative treatment combined with surgery had no impact on the prognosis of vocal fold leukoplakia.

No statistical difference could be found in above parameters between ACS-cVEMP and ACS-oVEMP (P>0.05). Conclusion:Both ACS-cVEMP and ACS-oVEMP could be elicited in guinea pigs. PMID- 30282174 TI - [Outcomes of same-day bilateral endoscopic tympanoplasty]. AB - Objective:To investigate the feasibility of simultaneous bilateral endoscopic for tympanoplasty in patients with bilateral chronic suppurative otitis media. Method:Fifteen patients (30 ears) with bilateral chronic suppurative otitis media who underwent bilateral endoscopic transcanal tympanoplasty on the same day were enrolled in this study. The ear with worse-hearing was selected as the first operation side, the contralateral ear as the second one. The operation group consisted of 22 ears of Type 1 tympanoplasty, 5 ears of Type 2 tympanoplasty and 3 ears of Type 3 tympanoplasty. All second sides(15 ears) underwent Type 1 tympanoplasty. The cartilage-perichondrium graft was harvested from the tragal of the first side and was cut in two halves which could be used for the both sides. The graft success and hearing improvement were evaluated at the postoperative 6th month according to the follow up results of the endoscopic image and the pure tone audiometry. Result:The graft take rate was 96.7%(27/30) without any retraction pockets or displaced grafts. The graft take rate of the first side was 93.3%(14/15), and the one of the second side was 100.0%(15/15). The average air conduction thresholds were (50.9+/-9.1) dB HL preoperatively and (32.0+/-6.0) dB HL postoperatively(P<0.01). The average air-bone gap overall improved from (30.2+/-7.9) dB HL preoperatively to (13.7+/-6.0) dB HL postoperatively(P<0.01). Conclusion:Bilateral same-day endoscopic tympanoplasty are safe and cost effective in appropriately selected patients. It can offer favorable out-comes in selected patients with chronic suppurative otitis media. PMID- 30282175 TI - [Cervical pharyngeal syndrome: a case report]. AB - Summary Cervical pharyngeal syndrome is characterized by the symptom such as sore throat, foreign body sensation or swallowing discomfort which caused by the pathological changes of cervical intervertebral disc and intervertebral structure nonspecific injury. Because of the lack of obvious specificity, it is easy to misdiagnose. Here, we reported a case of cervical pharyngeal syndrome. The symptom were obviously improved after conservative treatment, but the follow-up time is short, and further follow-up is needed. In the process of diagnosis and treatment, in order to reduce misdiagnosis and mistreatment, we should strengthen the understanding of the disease, broaden the clinical thinking, and understand the anatomical relationship between the pharynx and the surrounding organs.

AB - Objective:To identify the clinical risk factors related to the increased likelihood of surgical drainage and medical therapy failure in parapharyngeal and retropharyngeal abscess. Method:The charts of 93 consecutive patients from January 2006 to April 2017 with parapharyngeal and retropharyngeal abscess were reviewed retrospectively. Logistic regression analysis was used to study the clinical risk factors.Result:A total of 97 adult patients, there were 34 cases in the immediate surgical drainage group and 32 cases in the delayed surgical drainage group and 31 cases treated with medical therapy alone. The rate of operation therapy was 68%,and the success rate of the medical therapy alone was 32%. All patients had successful resolution of their abscesses by medical therapy and(or) surgical drainage. The average length of stay(17.26d) in the surgical drainage group was longer than the medical therapy group(10.26 d), and the difference was statistically significant(P<0.001).The maximum dimension of abscess>2.37cm is not only the risk factor of increasing likelihood of surgical drainage, but also that of medical therapy failure(P<0.001, P<=0.002).The factors affecting the hospitalization day were whether or not the operation was performed. There was no significant difference in operative rate between diabetic group and non?diabetic group(chi2=0.523,P>0.05).There were no correlation between diabetes mellitus and the multiple space abscesses(r= 0.032,P<=0.760).Conclusion:Although a majority of adult parapharyngeal and retropharyngeal abscesses were treated with surgical drainage and sufficient effective intravenous antibiotics,but not all patients need surgical treatment. The diameter of the abscess is a risk factor affecting the operation or not.For those with larger abscesses,the preoperative preparation should be actively prepared and the operation should be intervened as early as possible;for those with smaller abscess,the treatment can be cured alone, and the surgical incision and drainage should be avoided in order to reduce the complications and shorten the hospital days. PMID- 30282184 TI - [The clinical value of wideband tympanometry in the diagnosis of otitis media with effusion]. AB - Objective:To establish normative data for wideband absorbance measurements in Chinese with normal ear and effusion ear using wideband tympanometry(WBT) and determine the WBT curves of normal ears and effusion ears to facilitate the use of it. To investigate whether there are difference between the WBT absorbance in children aged 2-16 and adults above 16. To compare the sensitivity and specificity of WBT and conventional tympanometry tests for diagnosing otitis media with effusion (OME).Method:One hundred and seventy-six patients(342ears) ,from January 2015 to December 2015, were enrolled, including 96 males and 80 females whose ages ranged from 2 to 74 years. All of these patients, who underwent physical examination, ear endoscopy, conventional tympanometry and pure tone audiometry, were divided into three groups, namely normal, negative pressure and effusion according to the clinical diagnosis. WBT was carried out in these patients to analyze whether there are difference in the absorbance between children and adults in normal ears.The absorbance diagram of normal, effusion and negative pressure ears were mapped in Chinese population.The normal WBT curve was named as type N (normal) curve, the middle ear effusion curve as type E (effusion) curve, and the middle ear negative pressure curve as type P (negative pressure) curve. Pairwise comparison was carried out to analyze the difference of the WBT absorbance among these WBT curves. Other 40 patients (66 ears) with clinical diagnosis of middle ear effusion, including 22 males and 18 females with ages ranged from 3 to 36 years old, underwent exploratory tympanotomy. These 40 cases were detected preoperatively by both conventional tympanometry and WBT by which the sensitivity and specificity were compared in the diagnosis of middle ear effusion.Result:The normative data of WBT absorbance in Chinese with normal ear over 2 years old was established. The WBT absorbance at all frequencies between children and subject over 16 years old showed no statistically significant difference except for 10 frequencies in all 31 frequencies detected. The variations in the absorbance were mainly concentrated on the frequencies ranged from 500- 2000 Hz,in patients with OME. In the frequency range of 500-2000 Hz, the absorbance amplitudes in type N curv >type P curve>type E curve. There were significant differences in WBT absorbance at all frequencies between type N and type E between within 500-2000 Hz.The sensitivity and specificity of WBT for middle ear effusion were 94.8% and 87.5%, respectively, which were higher than that of conventional tympanometry with 91.3% of the sensitivity and 62.5% of the specificity.Conclusion:The WBT absorbance is consistent at most of the frequencies in Chinese. The normal ear, effusion and negative pressure in the middle ear can be distinguished by WBT curve. WBT can be useful for clinical diagnosis of OME, which has a higher sensitivity and specificity than conventional tympanometry.

AB - Objective:The cochlea of children with congenital sensorineural hearing loss with normal inner ear structure was measured and analyzed by high-resolution temporal bone CT(HRCT) imaging technique,its application value before cochlear implantation was evaluated and the appropriate electrode was selected.Method:We collected temporal bone HRCT images of 120 patients with congenital sensorineural hearing loss,according to gender divided into two groups,including 60 males and 60 females.We used the PACS software to measure the distance A(the largest distance from the round window to the lateral wall) and the distance H(height of the cochlea) and calculate the cochlear duct length. Reproducibility of these data were evaluated and the results between the different groups were compared.Result:Measurement of parameter values between the intraobserver and interobserver showed great reproducibility. In the male children group,the measured values are shown as distance A[(8.55+/-0.31)mm],distance H[(4.57+/ 0.28)mm]and the cochlear duct length(CDL)[(27.59+/-1.23)mm]; and in the female children group, the measured values are shown as distance A[(8.45+/ 0.32)mm],distance H[(4.42+/-0.34)mm]and the cochlear duct length(CDL)[(27.20+/ 1.17)mm.The A,H,and CDL of the male cochlea were greater than those of the female, the difference was statistically significant(P<0.05).Conclusion:Measuring the distance A and distance H of the cochlea and calculating the cochlear duct length CDL can be used to select a suitable length of electrode or to customize a personalized electrode. This is a simple and effective assessment method before cochlear implantation.. PMID- 30282186 TI - [Clinical features of papillary thyroid carcinoma patients associated with lateral lymph node metastasis in different ages]. AB - Objective:To explore the clinical features of papillary thyroid carcinoma(PTC) patients associated with lateral lymph node metastasis(LLNM) in different ages. Method:One hundred and sixty?five PTC patients associated with LLNM were included in the study and divided into three groups(22-<30y,30-<45y and 45-65y). The gender, the number and the ratio of neck lymph node metastasis, maximum tumor diameter, multifocality, preoperative serum thyroid stimulating hormone(TSH), the capsular invasion, extrathyroidal extension and other clinical features in different ages were analyzed.Result:The median age of the patients was 39 years. There were no significant differences in the maximum tumor diameter >1cm,multifocality and preoperative serum TSH level among the three groups. The proportion of female patients in 22-<30y group was higher than the other two groups(all P<0.05).The rate of bilateral lesions in 45-65y group was higher than 22-<30y group (P<0.01).The rates of the capsular invasion and extrathyroidal extension in 22-<30y group and 30-45 group were similarly lower than 30-<45y group(P<0.05).The proportion of the 22-<30y group coexistent with Hashimoto thyroiditis was higher than the other two groups(P<0.05). When the number of central lymph node metastasis(CLNM)>3,the proportion of 22-<30y group were higher than the other two groups(all P<0.01), the 30-<45y group was the same as higher than 45-65y group(P<0.05); When the ratio of CLNM>0.35,the proportion of 30-<45y group was significantly higher than the other two groups(all P<0.05).When the number of LLNM>6, 22-<30y group was significantly higher than the other two groups;when the ratio of LLNM>0.33, 45-65y group was lower than the other two groups(all P<0.05).The total lymph node metastasis>11, the proportion of 22-<30y group was significantly higher than the other two groups(all P<0.05), meanwhile 30-<45y was higher than 45-65y group(P<0.05);when the ratio of total lymph node metastasis>0.22,45-65y group was significantly higher than the other two groups(all P<0.01).Conclusion: There is a high proportion of female and maximum tumor diameter over 1cm in PTC associated with LLNM. The proportion of coexistent with Hashimoto thyroiditis and the number of lymph node metastasis are much higher in 22-<30y group. The higher ratio of CLNM is much more common in 30-<45y group. The bilateral lesions are more likely to occur in 45-65y group, and meanwhile the tumor is more easier to invade the capsular and extrathyroidal construction. The number and the ratio of total lymph node metastasis might be lower in PTC associated with LLNM of older patients.

AB - Objective:To discuss the correlation of benign vocal cord lesions with occult vocal cord sulcus and the treatment of benign vocal cord lesions with occult vocal cord sulcus, through the analysis of surgical data, preoperative voice evaluation data and postoperative follow-up data of patients.Method:The data from 377 patients of benign vocal cord lesions with concealed vocal cord sulcus admitted to Beijing Tongren Hospital from 2005 to 2016 were reviewed. The follow up time was more than half a year after surgery.Result:About 2.9% of the benign lesions of the vocal cords were associated with occult vocal cords sulcus,of which 61.27% were bilateral vocal cords sulcus,22.55% was right vocal cords sulcus,and 16.18% was left vocal cord sulcus.Of the patients with bilateral vocal fold sulcus,64.5% had benign vocal cord lesions and 35.5% had unilateral vocal cord benign lesions.Of the patients with unilateral vocal fold,73.97% were associated with ipsilateral vocal cord benign lesions, and 26.03% were associated with contralateral vocal cord lesions.In the 531 sides of the vocal cords sulcus,183 sides of vocal fold sulcus typeIwere not treated. The 332 sides of vocal fold sulcus type II were treated with removed lesions of the vocal cords and microdissection of vocal cord adhesion.The 16 sides of vocal fold sulcus type III were treated with removed lesions of the vocal cords,local tamponaded of autogenous abdominal fascia and microsutured to close the wound. There were 9 cases with 11 sides of vocal fold sulcus combined with the mucous bridge.The satisfactory rate of sound improvement was 80.37% in half a year after the operation.Postoperative fundamental frequency,jitter,shimmer and maximum phonation time were significantly improved compared with preoperative.Conclusion:The occurrence of benign vocal cord lesions may be related to occult vocal fold sulcus.Simultaneous treatment of benign vocal cord lesions with occult vocal cord sulcus can achieve satisfactory voice improvement.Therefore, we should pay attention to the treatment of vocal fold sulcus in the diagnosis and treatment of benign vocal cord diseases.

AB - Objective:To explore the value characteristics of preoperative and intra operative ultrasound in the diagnosis and treatment of parathyroid adenoma,and to further clarify the value of ultrasound in the diagnosis and treatment of parathyroid adenoma.Method:A total of 62 cases of parathyroid adenoma confirmed by postoperative pathology from March 2016 to November 2017 were collected, and the pre-operative ultrasound parameters were analyzed;and 26 cases were detected by intra-operative ultrasound.Result:In 62 cases of parathyroid adenoma, 58 cases of parathyroid adenoma were diagnosed by ultrasound before operation,and the sensitivity was 93.54%. Among the 26 cases,the lesions of 24 cases were detected by intra-operative ultrasound,and the sensitivity was 92.31%.Conclusion:Preoperative ultrasonography has a high diagnostic value for the qualitative diagnosis and location diagnosis of parathyroid adenoma, and intra-operative ultrasound can help to detect lesions quickly and safely, which is of great significance to shorten the operation time and improve the safety of operation. It is an important development space of ultrasound in the diagnosis and treatment of parathyroid glands. PMID- 30282191 TI - [Analysis and surgical treatment of 72 cases of parapharyngeal space tumors]. AB - Objective:To summarize and analyze the clinical features, diagnosis methods, surgical approaches and treatment outcomes of patients with parapharygeal space tumors.Method:A retrospective review of 72 cases with parapharygeal space tumors treated from March 1994 to June 2017 was performed. The data on presentation, surgical approach, histological diagnosis and postoperative complications were reviewed.Result:The postoperative pathological diagnosis included 62 benign tumors and 10 malignant tumors. The most frequent symptom was a cervical mass or an intraoral swelling. All patients underwent preoperative enhanced CT scan or MRI,which would be helpful to evaluate the tumor sizes,locations and possible sources,and to make operation scheme. The postoperative pathology included 24 salivary gland lesions and 30 neurogenic lesions. The postoperative complications happened in 13 patients. The surgical approaches included trans-cervical approach in 55 cases, cervical-parotid approach in 9 cases,trans-oral approach in 6 cases , and trans skull base approach in 2 case.Conclusion:A parapharygeal space tumor is an uncommon tumor and requires careful preoperative assessment. Surgery is the first choice for parapharygeal space tumors. These patients should be counseled appropriately about the potential for permanent cranial nerve deficits.

PMID- 30282196 TI - [Advances in the role of adenoid hypertrophy in the pathogenesis of otitis media with effusion in children]. AB - Adenoid hypertrophy(AH) and otitis media with effusion (OME) are both common diseases in pediatric otorhinolaryngology and are often associated with each other. Children are often diagnosed with otitis media with effusion and adenoid hypertrophy(OME/AH). Adenoids are immune lymphoid tissues of children's upper respiratory tract, and are important barriers against upper respiratory tract infections.During an upper respiratory tract infection,bacteria or viruses repeatedly stimulate immune lymphoid tissue to cause hyperplasia,and pathological hypertrophy is often accompanied by OME and other related symptoms.In recurrent or chronic OME, hyperproliferative adenoids are usually excised indicating that the two diseases may have a certain correlation. Recently,more and more studies have shown that AH plays an important role in the pathogenesis of OME in children. This article elucidates the role of AH in the pathogenesis of childhood OME from adenoid mechanical obstruction,adenoid bacterial and bacterial biofilm, adenoid local immune regulation, and IgE-mediated allergic reaction. PMID- 30282197 TI - [A brief introduction of local allergic rhinitis]. AB - Local allergic rhinitis(local allergic rhinitis, LAR) is a newly proposed concept in recent years. It refers to patients with typical allergic rhinitis symptoms but skin prick test (SPT) and serum specificity IgE are negative, while nasal mucosa can produce local specific IgE and allergen provocation test (NAPT) are positive. The rate of clinical misdiagnose is high. The diagnosis mainly relies on typical nasal symptoms, positive NAPT and/or detection of local specific IgE. It needs to be distinguished from allergic rhinitis(AR) and non-allergic rhinitis (NAR). The main mechanism of its onset is the Th2-type allergic inflammatory response mediated by locally produced IgE. Eosinophils and mast cells are also involved in the inflammatory process. The current study considers LAR to be a separate disease from AR. Allergen immunotherapy(AIT) can be used to treat the disease.. PMID- 30282198 TI - Reflective practice in psychiatric training: Balint groups. PMID- 30282199 TI - Five years of ECT: the relationship between consent status and treatment experiences. AB - OBJECTIVES: ECT has received limited systematic study in the Irish setting. Amendments to the Mental Health Act (2001) propose limiting the use of ECT to patients who can provide written informed consent. We report on the use of ECT in Limerick specifically addressing the issue of patient consent and how it relates to response rate. METHOD: Since 2003, the use of ECT within Limerick Mental Health Services has been monitored by a data gathering process that includes the documentation of mood disturbance before and after the procedure. RESULTS: In the five years between 2003 and 2007, 153 courses of ECT were given to 126 different patients (frequency 16.7/100,000; Female:Male = 2:1). The principal indication for ECT was depressive illness (95%). Bilateral electrode application was the preferred mode comprising 83% of use. A total of 60% experienced at least a 50% reduction in MADRS score over the course of ECT with 78% experiencing a reduction of 10 points or more on the MADRS. Higher response rate was linked to use of bilateral ECT (p = 0.007; 95% CI 1.3-13.6). A total of 14% of patients were unable to provide written informed consent and these patients had more severe depression at outset (p = 0.007; 95% CI 1.8-11.1) and a trend towards greater reduction in MADRS scores during ECT (p = 0.08). The commonest adverse incident associated with ECT was cognitive impairment (33 patients). The risk of cognitive problems was not related to age, ECT dose, number of treatments, severity of depressive symptoms, treatment response, or consent status. CONCLUSIONS: Frequency of use, response and adverse effect rates for ECT in Limerick Mental Health Services are similar to other centres. Cognitive impairment was the most frequent adverse event. The choice of electrode placement for ECT requires further consideration. Restricting ECT to patients that can provide written informed consent would prevent its use in many patients with severe illness who experience significant response to treatment. PMID- 30282200 TI - Reasons for referral and consultation liaison psychiatry diagnoses. AB - OBJECTIVES: Focused management strategies, including effective distribution of available resources is dependent on ongoing analysis of referral type in any liaison psychiatry consultation service. This survey sought to measure rate of diagnoses in an Irish liaison psychiatry consultation service, and compare the results with other similar services. METHOD: A survey of referral reasons and diagnoses was performed on all patients presenting to a Dublin based inpatient liaison psychiatry consultation service over two six month periods. The results were subsequently compared with other similar international studies. RESULTS: Commonest referral reasons were for depressive disorders, while commonest diagnoses included alcohol related disorders, depressive disorders, and delirium, with notably higher rates of alcohol related disorders than in other similar international studies. CONCLUSIONS: This study provides valuable information for referral reasons and diagnoses present in an Irish liaison psychiatry consultation service. The differences noted between diagnoses in our study and other international studies, as well as some of the difficulties in establishing these diagnoses, are discussed. PMID- 30282201 TI - Social and psychological correlates of happiness in 17 European countries. AB - OBJECTIVES: Happiness has been associated with a number of individual and societal factors, but much of the individual-to-individual variation in happiness remains unexplained. The purpose of this paper is to examine a broad range of social and psychological correlates of self-rated happiness in Europe. METHODS: We used data from the European Social Survey to determine levels of happiness in individuals (n = 30,816) from 17 European countries and to identify associations between happiness and age, gender, family relationships, satisfaction with income, employment status, community trust, satisfaction with health, satisfaction with democracy, religious belief and country of residence. RESULTS: Self-rated happiness varies significantly between European countries, with individuals in Denmark reporting the highest levels of happiness and individuals in Bulgaria reporting the lowest levels. On multi-variable analysis, happiness is positively correlated with younger age, satisfaction with household income, being employed, high community trust and religious belief. Overall, these factors account for 22.5% of the individual-to-individual variation in happiness in Europe. CONCLUSIONS: For the individual, this study highlights possible associations between happiness and the individual's attitudes towards various aspects of their personal, household and societal circumstances. For social policy-makers, this study suggests the potential usefulness of civic measures to increase community trust and social capital. Further studies of the inter relationships between individual and community-level variables would assist in further explaining the variance in happiness between individuals and countries. PMID- 30282202 TI - Stress in an Irish inner city emergency department revisited (2000-2006). AB - OBJECTIVES: Stress levels among staff in the Mater Misericordiae University Hospital Emergency Department were studied by questionnaire in 2000, which demonstrated a high level of self reported stress. The aim of this study was to ascertain if stress levels had reduced following changes in the department. METHOD: The study was repeated using the same questionnaire in 2006, after changes had occurred. RESULTS: There was a significant reduction in the percentage of staff that reported they were under severe or unbearable stress, from 37% in 2000 to 10% in 2006 (p = 0.002). A total of 60% felt the social environment of their work was satisfactory in 2006 compared to 40% in 2000 (p = 0.03). Compared to 2000, a significantly lower proportion reported they had a low degree of control over their job, and a significantly higher proportion reported a medium level of control over their job in 2006 (p = 0.03). CONCLUSIONS: Compared with the results of the previous study, reported stress levels have reduced overall, which coincided with a significant increase in staffing levels in the department. PMID- 30282203 TI - Combined antipsychotic use in a community rehabilitation psychiatric service. AB - OBJECTIVES: Despite the clinical guidelines regarding the use of combined antipsychotics and the limited evidence for its benefits, use remains high in psychiatric practice. The aim of this study was to examine prescribing practices and investigate reasons for initiating and continuing combined antipsychotics in stable psychiatric illnesses. METHOD: A cross-sectional case record survey of antipsychotic prescribing practices in a community psychiatric rehabilitation service. A total sample (n = 75) of patients with chronic and enduring psychiatric illnesses was studied. The age, gender, diagnosis and prescribed antipsychotics were examined. The proportional prevalence and documented reasons for combined antipsychotic prescribing were analysed. RESULTS: Seventy-three of the 75 patients were prescribed antipsychotic mediations. Of these, 44 (60%) received a combination of two or more antipsychotics. The most common reason for combined prescribing was a switch of antipsychotic (n = 18; 41%). No reason was documented in 19 cases (43%). CONCLUSIONS: In this study, slow cross-tapering or incomplete switch process of antipsychotics contributed to the prolonged period of combined antipsychotics treatment. Adequate documentation regarding indication and review of medications cannot be overemphasized. PMID- 30282204 TI - Expenditure of compensation from legal claims in an opiate dependent population. AB - This study examined the expenditure of compensation received from legal claims by service users attending an outpatient methadone programme in Dublin. Most claims (n = 62) were as a result of road traffic accidents (74%) or personal injury (15%). There were 28 reports of claims resulting in payment of compensation totalling ?912,871. Of the compensation not placed in trust (?477,871), almost 40% was spent on drugs and 8% on alcohol. Of those who reported no drug misuse at the time of the compensation being paid, seven out of 11 (64%) reported subsequently spending a significant amount on substance misuse. The risks of receiving large amounts of money in this population are substantial and include initiation and exacerbation of substance misuse, and risk of overdose. Alternative ways of managing the payment of compensation should be considered for this vulnerable population. PMID- 30282205 TI - An audit of incomplete involuntary admissions to an approved Irish centre. AB - OBJECTIVES: With the implementation of the Mental Health Act 2001 (M HA 2001) in November 2006, there was an expectation of reduction in the overall involuntary admission rate, particularly as those with a sole diagnosis of substance misuse were specifically excluded from the definition of mental disorder. The aim of this audit cycle was to ascertain this rate and to audit the process of the referral, transfer, assessment and subsequent management of the patients whose admission orders were not completed by the consultant psychiatrists (CPs) following referral for involuntary admission to an approved centre. In addition, the authors wished to ascertain if the recommendations of Audit 2003 were implemented. METHOD: The Audit 2003 analysed all Temporary Patient Reception Orders sent to an approved centre in the year 2003 but whose admission orders were not completed by the CP. A protocol was drawn up to elicit information. The Re-Audit in 2008 used the same protocol. The duration of the Re-Audit was 01.11.06-31.10.07. The results were analysed using SPSS 12. RESULTS: There is no change in the involuntary referral rate to the approved centre in Longford/Westmeath since the new legislation was enacted. The CP continues to refuse to make an order in one in three cases. Patients with a sole diagnosis of alcohol misuse continue to be referred for involuntary admission but are now presenting sober on admission. There also appears to be an increased rate of incorrectly filled forms by GPs. CONCLUSIONS: This audit indicates a need for more training for GPs and Gardai in the MHA 2001 and filling of forms. PMID- 30282206 TI - Irish adolescents with ADHD and comorbid substance use disorder. AB - OBJECTIVES: To examine the literature for drug treatment of attention deficit hyperactivity disorder (ADHD) in adolescents with co-occurring substance use disorder (SUD), the challenges posed by this, and make recommendations taking into account current trend in Ireland. METHODS: Articles published from 1992-2008 were identified using OVID-MEDLINE search using the search terms attention deficit hyperactivity disorder and substance use disorder. Studies cited include review articles, epidemiological studies, experimental researches, open and controlled trials of drugs in ADHD with comorbid SUD and clinical guidelines. No non-English language papers were included. RESULTS: Thirty-six studies were examined. A number of the papers reported on the link between ADHD and SUD, that they frequently co-occur, and there is evidence that treating ADHD can reduce the risk of future SUD. Some of the studies reviewed demonstrated the safety and effectiveness of ADHD medication on the ADHD symptoms but less so on the SUD. Concerns around stimulant abuse and diversion are valid. Although there is no current evidence of frequent diversion of ADHD medications in Ireland, this practice is prevalent in the US. Consequently psychiatrists should remain vigilant to the possibility of such diversions and take measures to address them if identified. CONCLUSIONS: The available evidence suggests that medication is not hazardous in ADHD comorbid with SUD. Pharmacological treatment of ADHD, following consideration of potential risks and benefits, is justified in the presence of SUD. Both methylphenidate and atomoxetine can be used. Stabilisation of serious SUD before pharmacotherapy is preferable, and it is advisable to provide psychological treatment to address SUD in these patients. PMID- 30282207 TI - A potential model for primary care mental health services in Ireland. AB - OBJECTIVES: A high demand for the inclusion of psychosocial interventions for primary care mental health presentations has become more apparent in recent years. Current policies have proposed models of care highlighting principles required for a quality service. However, implementation has been slow to date. This article aims to inform the current debate relating to primary care service delivery models for mental health presentations and to contribute towards future planning initiatives. METHOD: A narrative review of a range of policies and selected articles relevant to primary care mental health in an Irish context. RESULTS: The search produced four distinct themes: current service provision in Ireland; stakeholders' views; psychological care options; and potential service structures. Thereafter, a potential service delivery model is proposed. This formulated model employs a combination of elements from the reviewed themes to provide a clinically- and cost-effective, equitable and accessible service driven by service user and carer input. CONCLUSIONS: Although this review was selective in nature, the proposed potential model can complement future research agendas for more favourable primary care practice in Ireland. Recommendations are made for the planning of services including policy implementation procedures, training and communication. PMID- 30282208 TI - Depressive psychosis associated with a cyclo oxygenase 2 inhibitor (meloxicam). AB - We describe a 60 year old man who developed a fluctuating depressive psychosis associated with meloxicam, a non-steroidal anti-inflammatory drug (NSAID). The psychological symptoms observed were temporally related to the administration of meloxicam and occurred in the presence of signs of meloxicam intolerance, such as skin rash and raised blood pressure. The depressive reaction resolved quickly following cessation of meloxicam, recurring on re-exposure. The psychiatric manifestations of NSAID intolerance are rare, however 40% of cases have a history of mental illness. Data from adverse event reporting systems suggest that the newer NSAIDs (COX-2 inhibitors) may have a higher propensity to cause psychiatric adverse effects and should be used with caution in individuals with a history of mental illness. This data may be provocative given current research in to the use of COX-2 inhibitors in augmenting neuroleptic treatment in schizophrenia.

AB - Post-traumatic stress disorder (PTSD) and acute stress disorder (ASD) differ from almost every other psychiatric diagnosis in that they may only be diagnosed with reference to an aetiological event - an external traumatic stressor. ASD occurs immediately after the stressor and is comparatively short-lived, while PTSD is a prolonged abnormal response that may take months to develop. The types of stressor leading to ASD and PTSD are identical and were intended to be tightly defined, involving a perceived threat of death, serious injury or loss of physical integrity. It is useful initially to distinguish ASD and PTSD from adjustment disorders, which are also diagnosed only after an observable life event. An adjustment disorder may be thought of as a gradual and prolonged response to stressful changes in a person's life. The range of stressors precipitating an adjustment disorder is potentially much broader than that precipitating ASD or PTSD, as a threat of death or injury is not needed. Indeed, a 'threat' as such is not needed, as the event may be a loss. Events such as job loss or the breakup of a relationship may lead to an adjustment disorder, as well as threats such as accidents or assaults. The diagnostic criteria for adjustment disorder do not specify what the immediate response, if any, to the precipitating stressor must be. PMID- 30282213 TI - Facilitating journey to recovery. AB - The Irish 'Vision for Change', 2006 mental health policy document proposes a framework for promoting mental health and a recovery approach to inform every level of service provision. Comprehensive assessment by the rehabilitation and recovery multidisciplinary team with active involvement of the service user is crucial in the identification of needs, goals and recovery factors. This paper outlines importance of a comprehensive assessment tool, which helps to guide the service user towards identification and achievement of their goals while encompassing the recovery ethos. PMID- 30282214 TI - The economic cost of schizophrenia in Ireland: a cost of illness study. AB - OBJECTIVES: Although there are many published reports about the human cost of schizophrenia, there are far fewer estimates of its economic cost, particularly in Ireland. The aim of this study was to provide a prevalence-based estimate of the costs associated with schizophrenia in Ireland during 2006. METHOD: Using standard Cost of Illness (COI) procedures we compiled data from many sources including the Health Research Board, the Department of Health and Children and other government publications. Costs relating to health and social care, informal care, lost productivity, premature mortality and other public expenditures were included. Where national data were unavailable, we used bottom-up data from a geographically defined catchment area study and, in some instances, costs from two catchment areas were averaged. We did not measure human or intangible costs. RESULTS: The estimated total cost of schizophrenia was ?460.6 million in 2006. The direct cost of care was ?117.5 million and the burden of indirect costs was ?343 million. The cost of lost productivity due to unemployment, absence from work and premature mortality was ?277 million. Within indirect costs, the expenditure on informal care borne by families was ?43.8 million. CONCLUSIONS: Schizophrenia is not a very common condition but is an expensive one. This is attributable to its young age at onset, relatively low mortality rate and high severity particularly in terms of its impact on future employment. Measures to improve outcomes coupled with measures to improve employment such as supported employment strategies may impact significantly on the cost of schizophrenia. The study is limited because the national unit costs of many variables are not directly available and these Irish data are likely to be an underestimate. However, the results are comparable with a 2005 cost of illness study UK study. PMID- 30282215 TI - Children's depression, gender and age norms for an Irish national (primary) school population. AB - OBJECTIVES: To provide normative data for older national (primary) school children, broken down by age and gender, for the Children's Depression Inventory Short version (CDI-S) and revised norms for the Children's Depression Inventory Parent version (CDI-P) and its subscales. METHOD: Forty-three randomly selected national schools took part in this study. Participants were 1,255, fifth and sixth class, Irish national school children who completed the Children's Depression Inventory Short Form (CDI-S). In total 1,018 parents completed the corresponding parent form, the Children's Depression Inventory-Parent version (CDI-P). RESULTS: Norms for the CDI-S and the CDI-P subscales were produced. Revised norms for the CDI-P are proposed. Results revealed no significant age or gender difference in depressive symptomatology as measured by respondent's CDI-S and total CDI-P scores. Parent's ratings of their children's depression levels (CDI-P) and children's self-reported depression levels (CDI-S) were significantly correlated. The CDI-S and CDI-P displayed good internal reliability. CONCLUSION: Results indicate the utility of both the CDI-S and the CDI-P for assessing depressive symptoms in national school children in Ireland. This study confirms that national school children do display symptoms of depression. School based policies, materials and services supporting and promoting positive mental health should be developed, implemented and resourced. PMID- 30282216 TI - Bone mineral density and general health of long-term residential psychiatric inpatients. AB - OBJECTIVE: The aim of this study was to determine the rates of osteopenia and osteoporosis and other general health problems in a long-stay male psychiatric unit. METHOD: All 15 patients underwent a semi-structured clinical interview and a full physical examination including calculation of Body Mass Index, central obesity (abdominal circumference) and blood pressure measurement. All patients had blood sampling examining FBC, U&E, LFTs, TFTs, PSA, prolactin, lipid profile and glucose. The rates of metabolic syndrome were calculated according to the International Diabetes Federation consensus worldwide definition. Bone mineral density was determined in the lumbar vertebrae and left hip by DEXA scanning. RESULTS: The prevalence of osteopenia or osteoporosis was 46%, and bone mineral density was inversely correlated with serum prolactin levels (r = -0.595, p = 0.041) and chlorpromazine equivalence (r = -0.645, p = 0.017). The prevalence of obesity was 53%, while central obesity was present in 87% of patients. Metabolic Syndrome was present in 27% of patients. CONCLUSIONS: More attention should be given to diagnosing and treating osteopenia and osteoporosis in patients on long term antipsychotic agents and preventative measures should form part of any treatment regime in these individuals. Frequent input from dietitians should also be available for long-stay psychiatric inpatients to reduce the prevalence of obesity. PMID- 30282217 TI - Ireland's long-stay charge refunds: mental capacity and dilemmas in a psychiatric institution. AB - OBJECTIVE: All patients who resided in state provided long-stay care in Ireland were required to pay the state for that care until 2006. In 2001 the Irish Ombudsman and Information Commissioner had highlighted the issue of the entitlement of people with medical cards to provision of free long-stay care. The Health Repayment scheme was subsequently set up in 2006 to facilitate the repayment of long-stay charges wrongly paid by patients. Issues of mental capacity arise particularly in the context of long-stay psychiatric patients applying for repayment of long-stay charges. Our aim was to devise a test suitable to assess the capacity of an individual to make an application for refund charges. METHOD: There was no specific test in existence to assess the capacity of an individual to make an application for refund of charges. A suitable test was devised based on the available literature which assessed whether the person understands the 'nature and effects' of making a refund application. Fifty-eight long-stay patients were deemed to be entitled to apply for a refund. RESULTS: Staff identified 47 (80%) patients as possibly lacking the capacity to make an application. Of these, 14 patients (29.8%) were found to have capacity to make an application (mean age 58.5 years) with 33 (70.2%) found to lack capacity (mean age 73 years). Of those with capacity 50% had a diagnosis of schizophrenia/schizoaffective disorder. None had cognitive impairment of degenerative origin. Of those who lacked capacity 45.5% had a diagnosis of dementia. All of the patients with dementia who were assessed were found to lack capacity whereas 59% of those with a diagnosis of schizophrenia/schizoaffective disorder lacked capacity. CONCLUSION: A substantial number of long-stay psychiatric patients may lack the capacity to make particular decisions. In this study the group who lacked capacity were an elderly group with dementia common. This process raised a dilemma about how a patient without capacity to make a refund application can then manage the money claimed on their behalf and whether guardianship safeguards are necessary. PMID- 30282218 TI - An exploration of the relationship between social support and depressive symptoms in schizophrenia. AB - OBJECTIVE: Depressive symptoms in schizophrenia have previously been associated with a perceived lack of social support. The aim of this study was to explore the relationship between perceived social support and depressive symptoms in schizophrenia; to assess the psychological wellbeing of their carers; and to examine the quality of the relationship between the patients and their carers. METHOD: Individuals with schizophrenia (n = 17) were assessed on the Beck Depression Inventory (BDI), the Beck Hopelessness Scale (BHS), a measure of perceived social support, the Significant Others Scale (SOS) and the Quality of Relationship Inventory (QRI). RESULTS: The mean score on the BDI for patients fell within the moderate-severe range and the mean range on the BHS fell within the moderate range. Family and friends were perceived as supportive resources by patients. There was no significant relationship between patient depressive symptoms or hopelessness and perceived social support. Carers of patients did not report high rates of depressive symptoms or hopelessness. CONCLUSIONS: These findings do not support the previous finding of an association between depressive symptoms and a perceived lack of social support in schizophrenia.

PMID- 30282220 TI - Learning disability and forensic mental healthcare in 19th century Ireland. AB - The Irish College of Psychiatrists recently reported that "the needs of people with learning disability and offending behaviour pose a huge challenge to service providers. The vulnerability of people with a learning disability who come into contact with the criminal justice system is well described and noted." The College noted that "the population with learning disability who offend does not easily fit into existing services" and reported that "the majority of service providers strongly supported the urgent development of a forensic learning disability service." The challenges presented by individuals with learning disability and offending behaviour are not specific to Ireland or to this period in history. The purpose of the present paper is to explore issues related to learning disability and offending behaviour in 19th- and early 20th-century Ireland. More specifically, this paper presents original, previously unpublished case material from the archival medical records of the Central Mental Hospital, Dublin in order to illustrate specific aspects of the institutional experience of individuals with learning disability who were charged with offending behaviour in nineteenth-century Ireland. The Central Mental Hospital, Dublin was established as the Central Criminal Lunatic Asylum in 1845 under the provisions of the Lunatics Asylums (Ireland) Act (1845). Individuals were to be committed to the Central Criminal Lunatic Asylum if they were declared 'guilty but insane' at time of trial or offence, or if they developed mental illness and became difficult to manage while in detention elsewhere. The Central Criminal Lunatic Asylum opened its doors to admissions in 1850 and by 1853 there were 69 male and 40 female inpatients. PMID- 30282222 TI - Patient attitudes towards compulsory community treatment orders and advance directives. AB - OBJECTIVES: The Mental Health Act 2001 was implemented in Ireland in 2006, however, within this new legislation there is no provision for compulsory community treatment or advance directives, which are now established practice in other countries. We aimed to determine the proportion of patients who believe that compulsory treatment may be justified, the preference for where the treatment should be delivered and factors which may influence this preference. We also sought to determine the proportion of people who would be interested in the option of having an advance directive in their future care plan. METHODS: Patients who had been admitted involuntarily in a 183 bedded psychiatric hospital in Dublin (St John of God Hospital) over a 15 month period were interviewed one year following discharge. A structured interview was used and included the Birchwood Insight Scale and Drug Attitude Inventory (DAI). RESULTS: Sixty-seven patients were interviewed, which resulted in a follow-up rate of 68%. A total of 56% of participants believe that there are situations in which involuntary treatment with medication may be justified. Of the participants 59% think that the person should be admitted to hospital if they are going to be administered medication without consent. A total of 41 % of participants stated they would have preferred to have been treated at home rather than hospital and this was associated with having a diagnosis of an affective disorder or it being their first involuntary admission. Of the participants 84% expressed interest in having the option of an advance directive in their treatment care plan. CONCLUSIONS: With the increasing community based provision of mental health services in Ireland a debate on compulsory community treatment orders and advance directives needs to take place amongst all stakeholders. PMID- 30282223 TI - Carer-rated needs assessment of a cohort of people with dementia. AB - OBJECTIVES: With increasing longevity, more people will develop dementia. These people will have a wide range of needs according to their circumstances. Services in the community struggle to meet these needs. This study aimed to identify needs of dementia sufferers attending the South Dublin Old Age Psychiatry service as rated by their carers, to assess the extent of unmet need and the implication of this. METHOD: The carers of 40 community-dwelling people with dementia attending the service were interviewed by one researcher using the Camberwell Assessment of Need for the Elderly (CANE). This measures a wide range of needs over 24 areas, from personal care, to social, financial and psychological care needs. Qualitative information was also obtained from carers regarding services available and their accessibility. A measure of carer stress and satisfaction with help for this was also obtained. RESULTS: Overall, the highest levels of need identified (both met and unmet) were in the areas of psychological functioning (memory and psychological distress), followed by social needs in the areas of managing money, daytime activities, self-care, and looking after the home. Highest unmet social needs were in the areas of daytime activities, home care and managing money. For 23/24 domains, carers were satisfied rather then unsatisfied with help received. The areas of greatest dissatisfaction to them concerned daytime activities, household skills and self-care. Over half of the carers reported psychological distress. CONCLUSION: High levels of need, both met and unmet were identified. Many identified needs related to the provision of community supports in the areas of selfcare, household skills and daytime activities, in addition to psychiatric needs. Assessment of needs is important to ensure adequate and responsive service provision, in keeping with the ethos of community care. PMID- 30282224 TI - Consultant psychiatrists' experience of workplace violence - a national survey. AB - OBJECTIVES: In recent years there have been a number of high profile cases in Irish psychiatry where consultant psychiatrists have been subjected to serious physical assaults. The last survey of assaults on consultant psychiatrists in Ireland was carried out in 1998. Therefore we sought to update the data on this topic. METHOD: An anonymous questionnaire was sent out by post to all consultant psychiatrists (n = 330) identified as currently working in the Republic of Ireland. RESULTS: The response rate was 48.2%. Sixty per cent of respondents were working in general adult psychiatry and respondents were evenly spread throughout the country. Ninety per cent of respondents had been the victim of verbal aggression/intimidation/threatening behaviour while 55% had been physically assaulted. The majority of incidents involved male patients aged between 21-40 years with a diagnosis of paranoid schizophrenia. Nearly 66% of incidents of physical violence occurred during a relapse of illness. The perpetrator had a history of violence in approximately half of all reported incidents. Physical assaults tended to occur more commonly in inpatient settings (63.7%). Incident reporting occurred more often in physical assaults with 66% reported informally to colleagues and 20% reported to An Garda Siochana (police force of Ireland). Eighty-nine (56%) consultants described feeling 'safe' at work. Less than 50% reported the provision of standard safety equipment in the workplace and nearly half ofrespondents had not attended any safety training courses since their appointment. Longer experience working as a consultant psychiatrist did not appear to have an impact on reducing the rate of assaults. In addition, those who attended safety training courses did not report a reduced rate of physical assaults. CONCLUSIONS: These findings highlight the need for both organisational and personal changes in practice in order to reduce the assault rate. Organisational changes include the provision of appropriate safety equipment, safety training for consultants, enhancing multidisciplinary teams and utilising risk assessment. Consultants' personal practices to improve their safety may offer useful information for inclusion in safety training courses. This is an area which merits further research. PMID- 30282225 TI - Analysis of prescribing practices in an acute psychiatric ward. AB - OBJECTIVES: Prescription writing is a basic clinical skill for all doctors; however, errors in prescriptions are frequent and can result in significant harm to patients both from sub-therapeutic dosages and from over prescribing. This study examines the prescribing practices of 'as required' medications in an acute psychiatric inpatient unit attached to a university teaching hospital. METHOD: A clinical audit was conducted to examine both prescribing practices of 'as required' medication and recording of 'as required' medication in nursing notes. A series of educational interventions were undertaken in an attempt to improve prescribing practices in relation to 'as required' medication and two further audits were completed to assess any change in practice and whether such changes were sustained. RESULTS: Psycho-education led to an improvement in a number of prescribing practices, including increased generic prescribing, improved documentation of indications for medication administration and increased writing of medication dosages in acceptable abbreviations. These benefits were maintained four months after the education interventions. Rates of documenting the frequency of medication correctly and recording the administration of medication in nursing notes remained low. CONCLUSION: Our audit cycle clearly demonstrates that education can ameliorate prescribing practices and these improvements were maintained four months after education was delivered. However some aspects of prescribing practice remained deficient, and more focused educational interventions are required in these areas. PMID- 30282226 TI - Are you looking at me? Paranoid psychosis in pre-existing social phobia. AB - OBJECTIVES: Three patients presenting with a first episode of psychosis each had a past history of social phobia. We sought to explore the literature on the co occurrence of these disorders and investigate three hypotheses to explain this: (1) the chance co-occurrence of two illnesses with distinct aetiologies; (2) two clinical presentations reflecting different points on the same spectrum of illness; and (3) two distinct disorders representing different end points resulting from the same aetiology. METHOD: A literature review of Embase, PubMed and Psych Lit was performed. RESULTS: We found no reports on social phobia preexisting an episode of psychosis, and prevalence studies indicate that their chance co-occurrence is extremely unlikely. Psychological explanations for co occurrence include attributional theories, and theories related to cognitive biases and loss of self-esteem. CONCLUSION: There is a phenomenological overlap between social phobia and paranoia but the two concepts should and can be distinguished. Epidemiological studies indicate that their chance occurrence as two unrelated disorders is unlikely. Most people with one of these disorders do not develop the other and hypothesis (2) is also unlikely. There is increasing speculation that anxiety, and in particular social phobic symptoms have a central role in the development of psychotic symptoms. The greatest evidence was found to support hypothesis (3). However, it seems more likely that social phobia and psychosis, rather than representing manifestations of the same illness, instead are implicated in a complex interaction where symptoms which characterise social phobia and psychosis, have the capacity to affect, alter and possibly provoke each other. The recognition and treatment of co-occurring anxiety disorders, especially social phobia with psychosis, may have an important impact on prognosis and quality of life. PMID- 30282227 TI - Do we need community treatment orders in Ireland? AB - OBJECTIVES: Re-admissions to inpatient psychiatric care are now so frequent as to be designated the 'revolving door' phenomenon and constitute 72% of admissions to Irish inpatient psychiatric units and hospitals. It is commonly believed that treatment non-adherence with aftercare following inpatient discharge contributes to readmission. Attempts to improve adherence and reduce or shorten readmission through compulsory community treatment orders have been made in several countries including Scotland in 2005 and, from November 2008, England and Wales. Provision for conditional discharge in Ireland has already been furnished by the Criminal Law (Insanity) Act 2006 but has been compromised by the inability to impose enforcement of conditions. The paper aims to determine whether compulsory community treatment orders are effective in improving adherence and reducing re admission and whether, in consequence, their introduction in Ireland should be considered. METHOD: The legislative measures adopted to improve treatment adherence and thereby reduce re-admissions are presented. The evidence of their effectiveness is examined. RESULTS: Evaluation of the effectiveness of community treatment orders is limited and hindered by confounding factors. What evidence there is does not provide convincing evidence of their utility. CONCLUSIONS: It is concluded that there is insufficient evidence to advocate their early introduction in Ireland in civil mental health legislation. Instead a wait and see policy is suggested with critical assessment of the outcome of such developments in Scotland and England and Wales. In addition further research on the characteristics of revolving door patients in Ireland and the circumstances determining their readmission is advocated. There is an anomaly in the Criminal Law (Insanity) Act 2006 which allows of conditional discharge but does not provide for its enforcement. PMID- 30282228 TI - Bipolar affective disorder as the initial manifestation of multiple sclerosis. AB - The association between bipolar affective disorder and multiple sclerosis continues to be poorly understood in view of the limited knowledge and research in this field. Here we present the case of a 43 year old female with bipolar affective disorder who later developed multiple sclerosis. The relationship between the two disorders is discussed in the light of relevant and pertinent literature. It is hypothesised that bipolar affective disorder may be the presenting manifestation of multiple sclerosis and should be considered as a differential diagnosis in patients of bipolar affective disorder with neurological symptoms.

AB - Antipsychotic related urinary symptoms are recognised and they remain a potential treatment-limiting sideeffect of clozapine. This article reports the incidence and management of two cases of clozapine-associated incontinence in psychiatrically stable patients. Both cases occurred during treatment and appear to have a similar pathophysiology, which may be related to the atypical nature of clozapine therapy. We searched the PubMed and MEDLINE databases for articles published from 1980 to 2008 that contain the keywords 'clozapine and enuresis, 'clozapine and incontinence,' 'clozapine and seizures'. We also manually searched the bibliographies of these articles for related sources, and explored the reported treatment options to this side-effect of clozapine therapy.

AB - Jealousy is a commonly experienced emotion which has been observed in infants as young as 5-6 months of age and across the lifespan of an individual. In its extreme form jealousy can be pathological, when the belief which may be a delusion, obsession or an overvalued idea, is held on inadequate grounds and is unaffected by rational discussion. Morbid jealousy differs from normal jealousy in its intensity or rationality. It can be thought of as hypersensitive jealousy since jealous reactions are experienced at a much lower threshold than in average individuals. Morbid jealousy is a disorder in which an individual believes that their partner is, or will be, sexually unfaithful. Morbid jealousy can occur when a partner is in fact being unfaithful, provided that the evidence for the infidelity is incorrect and there is an excessive or irrational response to such evidence. The preoccupation with the partner's infidelity is often triggered by vivid mental images of their partner's past or present relationships.

AB - OBJECTIVES: To describe the prevalence of psychiatric morbidity and the treatment needs of new committals to Irish prisons. METHODS: A population survey of 615 prisoners representing 7.9% of male committals to Irish prisons in the year of survey, 313 remands (9.6% of total remand committals) and 302 sentenced committals (6.4% of total sentenced committals). The main outcome measures were ICD-10 diagnoses of mental disorder based on interviews using SADS-L and prison medical records. RESULTS: Current prevalence rates of any psychotic illness were 3.8% (remand) and 0.3% (sentenced), six month prevalence rate 5.1% (remand) and 2.6% (sentenced) and lifetime rate 9.3% (remand) and 6.6% (sentenced). Schizophrenia and drug/organic psychoses were the most common psychoses. Major depressive disorder had a current prevalence of 4.5% (remand) and 4.6% (sentenced), a six month prevalence of 4.8% (remand) and 6.0% (sentenced), and a lifetime prevalence of 8.6% (remand) and 15.9% (sentenced). Sixty-point-six per cent of the sample had a current substance misuse problem. CONCLUSIONS: There is significant psychiatric morbidity in committal prisoners. PMID- 30282237 TI - Psychogenic non-epileptic seizures in an Irish tertiary referral centre for epilepsy. AB - OBJECTIVES: To examine the prevalence, psychiatric co-morbidity and management of psychogenic non-epileptic seizures (PNES) in patients admitted to a tertiary referral Epilepsy Monitoring Unit (EMU). METHODS: Medical records of patients admitted to the EMU between 2003 and 2005 were examined and data from neurological, neuropsychiatric and neuropsychological assessments were analysed. RESULTS: Over a three year period 224 patients were referred to the EMU and 44 (20%) were diagnosed with psychogenic non-epileptic seizures (PNES). A total of 13 people (6%) were diagnosed with both PNES and epilepsy. Of those diagnosed with PNES 34 (75%) were referred to psychology services for cognitive behavioural therapy (CBT) and 26 (58%) were followed-up by psychiatry services. CONCLUSIONS: The prevalence rates for PNES and co-existing PNES and epilepsy are consistent with previous reports. Rates of psychiatric co-morbidity were less than would be expected in this clinical population. Clear evidence-based guidelines to manage people with PNES are required. PMID- 30282238 TI - Has the Mental Health Act 2001 altered the clinical profile of involuntary admissions? AB - OBJECTIVES: To assess whether transition from the Mental Treatment Act (MTA), 1945 to the Mental Health Act (MHA), 2001 has had any impact on the clinical profile of patients in the West Galway Mental Health Services who are admitted on an involuntary basis. METHODS: Data were collected from clinical records in relation to all those individuals residing in the West Galway Mental Health Services who were admitted involuntarily in the 12 months prior to and subsequent to the introduction of the MHA 2001. RESULTS: A total of 175 individuals were included in this study (n = 91 - MTA 1945; and n = 84 - MHA 2001). No significant differences were found between the two groups in relation to demographic data, rates of involuntary detention or duration of involuntary detention. The applicant was less likely to be a family member under the MHA 2001 (54%) than the MTA 1945 (85%). CONCLUSIONS: Transition from the MTA 1945 to the MHA 2001 has had minimal impact on the admission rates, clinical profile or duration of detention of patients admitted involuntarily in the West Galway Mental Health Services. PMID- 30282240 TI - Implication of rates of referral to a specialised inpatient neuropsychiatry team. AB - OBJECTIVES: This study examined and compared the number and pattern of referrals from neurosurgery and neurology specialist services to the inpatient liaison neuropsychiatry service in the years 2002 and 2005. We estimated the prevalence of psychiatric illness and evaluated the results of subsequent psychiatric assessment and follow-up of all patients reviewed by the neuropsychiatry service. METHODS: The medical notes of those patients referred to the neuropsychiatry team were retrospectively examined to obtain appropriate information on assessment and management of these cases. RESULTS: There were 544 referrals over the two years selected for study. Rates of referral to the inpatient neuropsychiatry service increased overall by 35% between 2002 and 2005. Overall, referrals from neurology comprised 85%, neurosurgery 15%. Patients with epilepsy comprised the majority of referrals (36%). A total of 378 (73%) had an acute psychiatric disorder and this group had a significantly higher rate (p = 0.01) of past psychiatric disorder (40%) than that in those with no acute mental illness (33%). Depressive episode was the most frequent acute psychiatric diagnosis (38%), followed by anxiety and organic psychiatric disorder (both 15%). Overall, 21% of patients diagnosed with acute mental illness were referred on discharge to the neuropsychiatry outpatient clinic for specialist follow up and the remainder followed-up by either local mental health teams or their GP. CONCLUSIONS: These findings provide clear evidence that further resources should be allocated to expanding neuropsychiatry mental health services to improve detection and management of mental illness in this vulnerable patient group. PMID- 30282239 TI - Opiate substitution prescribing in Belfast - two year follow up study. AB - OBJECTIVES: The objectives of the study were to identify the characteristics of the patients who were commenced in a newly developed opiate substitute prescribing (OSP) programme, to determine their rate of retention and to ascertain the patients' opinions of the service. We also wished to determine rates of blood borne viruses in this population. METHODS: Data were collected from three sources: the Shaftesbury Square Hospital Substitute Prescribing Database, patient charts and an anonymous user views questionnaire. We also conducted viral screening. Inclusion criteria were opiate dependence according to ICD-101 for at least one year, in individuals who were 18 years of age or older. The sample comprised the first 80 patients who attended the service, who were followed up over two years. RESULTS: A total of 44% of our original cohort remained engaged with the service two years after commencement. Of the remainder, 18% engaged with OSP elsewhere and 13% completed a successful detoxification from all opiate drug use. Factors which were associated with continuation in the programme were prescription of methadone (as compared with buprenorphine), female sex and higher doses of OSP. Patients reported high levels of satisfaction with the service. Of those who were tested for blood borne viruses, more than half were positive for hepatitis C infection. CONCLUSIONS: The response to the development of the opiate substitution programme demonstrated that there was a need in the community which had not been met in the past. Service users who attended the programme reported high levels of satisfaction. PMID- 30282241 TI - Dual diagnosis in a Dublin tertiary addiction centre - A cross-sectional study. AB - OBJECTIVES: To address the relative dearth of information relating to the prevalence of psychiatric co-morbidity among attenders of community addiction facilities. METHODS: We carried out a cross-sectional study of clients attending a Dublin-based tertiary addiction centre to assess the rates of psychiatric co morbidity, determine the demographic and clinical variables and evaluate the level of contact with allied medical care especially primary care and community psychiatric services. Information was sourced from available patient records. RESULTS: Forty-three per cent of the clients (n = 59), attending the service were found to have a chart diagnosis of psychiatric disorder. Only 15% of these were in contact with community psychiatric services. CONCLUSIONS: This high rate of psychiatric co-morbidity has implications in terms of funding, training and service delivery. PMID- 30282242 TI - Current psychotherapy training for psychiatry trainees in Northern Ireland. AB - OBJECTIVES: To investigate psychotherapy training for psychiatry trainees in N.Ireland. METHOD: A detailed survey of both trainee's current experience and completion of Royal College requirements. RESULTS: While trainees rated experience highly in terms of enjoyment and relevance to psychiatry, we found a large proportion (94%) were failing to meet requirements for psychotherapy training, despite awareness being high (91%). Both cognitive-behavioural and psychodynamic therapy were the predominant models of therapy trainees had experience in and although most supervision was rated highly, a number of trainees had irregular or no case supervision. CONCLUSIONS: At a time when it is becoming increasingly recognised that psychological therapies play a central role in the treatment of many psychiatric disorders, current training fails to provide a substantial experience. With such a high proportion of trainees not meeting the mandatory requirements and similar findings being replicated in other parts of the UK, serious consideration must be given to both the nature of the guidelines and the opportunities for psychotherapy training if future psychiatrists are going to be equipped to deliver a truly biopsychosocial model of care. PMID- 30282243 TI - 'Recovery' - towards integration into an Irish community mental health team. AB - OBJECTIVES: We aimed to further our understanding of the concept of recovery by analysing comments made in small group discussions that occurred on a planning Away Day held by a community mental health team along-side service users and carers, which had recovery as its theme. The purpose of this was to reshape the structure and workings of the team. METHOD: Five small groups, of approximately 10 individuals each, comprised of service-users, carers, representatives from voluntary organisations and mental health professionals were asked to discuss three questions related to Recovery. RESULTS: The commentary reflected previous qualitative research on the philosophy of recovery. Issues that were raised included defining wellness as independent to illness, constructive risk taking, the importance of social factors, medication issues and the importance of self management and optimism. The comments subsequently went on to shape community mental health team service delivery. CONCLUSION: Discussion and reflection between mental health professionals, service users and carers can lead to a change in attitude and practice in a well-resourced, fully multi-disciplinary community mental health team, within which both the biological and non-biological aspects of mental illness are accepted. The result has been an introduction of service changes which have helped develop a team that is more accessible and increasingly collaborative. PMID- 30282244 TI - The borderlines of bipolar affective disorder. AB - This paper provides an overview of the major studies of bipolar affective disorder (BAD) and borderline personality disorder (BPD), and assesses whether the disorders might be better understood as variants of the same basic disorder. There is a shortage of research that delineates the features of both disorders within their representative samples. As a consequence the symptomatic overlap of the disorders, detected by categorical assessment instruments, is often misconstrued as an indication of the disorders' high rates of comorbidity (up to 81%). In paying particular attention to features of both disorders, eg. affective instability and impulsivity, the paper provides evidence that BPD attenuates bipolar disorder along the spectrum of affective disorders, from non-classical bipolar presentation through to severe BAD with borderline features. The paper cites clinical, research and pharmacologic support of the contention that BPD, rather than representing a distinct disorder, is merely an attenuation of Axis I disorders, most especially bipolar affective disorder. Borderline personality is evident across the bipolar spectrum and exacerbates symptomatology and leads to poorer recovery prognosis.

PMID- 30282248 TI - Risk stratification and the care pathway. AB - OBJECTIVES: It was hypothesised that patients admitted to forensic mental health facilities are stratified along the pathway through care according to levels of need. Level of risk and psychopathology should vary with different levels of security. METHOD: Seventy-five men in a forensic hospital were interviewed by three trained clinicians using the HCR-20 (Historical Clinical Risk Assessment) - clinical and risk items, The Health of the Nation Scales - Secure (HoNOS-SECURE), PANSS (Positive and Negative Syndrome Scale), GAF (Global Assessment of Functioning) and the CANFOR (Camberwell Assessment of need Forensic Version). RESULTS: The mean scores on a variety of clinical measures were higher in admission/high security areas and progressively lower in rehabilitation and pre discharge areas. As patients moved through the pathways of care, they improved in a number of areas including psychiatric morbidity, risk, function, unmet needs. The following results stratified significantly; the HCR-20 summated clinical and risk (F = 9.2, df = 5, p < 0.001), the HoNOS secure (F = 18.2, df = 5, p < 0.001), PANSS (positive, general and total), GAF, staff and user unmet needs on the CANFOR. CONCLUSIONS: The data indicate that the theoretical organisation of the units of the hospital into high, medium and low security units to form a coherent pathway through care is reflected in practice. This is a transparent route out of secure care in which restrictions are proportionate to risk and supports proportionate to need. It is unclear whether alternative models, consisting of a series of generic unstratified units for admission and discharge, all at the same level of therapeutic security, allow for the provision of treatment programmes and relational interventions appropriate to the patient's stage of recovery and rehabilitation. PMID- 30282249 TI - Management of patients' physical health in an acute psychiatric unit. AB - OBJECTIVE: The aim of this study was to help clarify the range of acute medical problems experienced by patients on an acute psychiatric unit during a period of 28 days and nights, as encountered by psychiatric trainees, and to document any difficulties experienced by the trainee during these patient contacts. METHOD: This survey was carried out prospectively over 28 days and nights in an acute psychiatric ward attached to a teaching University Hospital. Following contact with an individual patient, the trainee recorded diagnosis, intervention and any difficulties encountered. RESULTS: Thirty-three patient contacts were recorded (n = 33). Trainees faced a range of primary care problems 22/33 (67%), but moreover, three patients demonstrated more serious and potentially life threatening problems, leading to 11/33 (33%) patient contacts requiring urgent interventions. CONCLUSIONS: While the debate continues as to who is best placed to provide medical healthcare for psychiatric patients, this study provides evidence that psychiatry trainees are required to draw on their previous medical and surgical experience on an almost daily basis. As psychiatrists we should consider our options on how best to manage medical problems on the acute psychiatric unit and consequently ensure confident liaison with our medical and surgical colleagues. PMID- 30282250 TI - Staff attitudes towards particular client difficulties in assertive outreach teams. AB - OBJECTIVE: Over recent years in England there has been widespread development of assertive outreach teams supporting patients with severe mental illness living in the community. Assertive outreach staff members are exposed to a variety of new stressors and risks. This study investigated the emotional impact on keyworkers of working with assertive outreach patients. This was considered in terms of the attitudes keyworkers hold towards patients with particular types of difficulty. The study also measured individual keyworker stress. METHODS: Keyworkers from three teams in Birmingham were surveyed regarding their attitudes towards individual patients. Questionnaires measuring attitudes and patient difficulties were derived for the purpose of the study. Strengths of attitudes were correlated against different patient difficulties. Keyworker stress was measured using the General Health Questionnaire, GHQ12. RESULTS: Certain patient difficulties, in particular poor engagement, psychotic symptoms and aggression were associated with feelings of failure in keyworkers whilst drug use, particularly crack cocaine use, was associated with fear of visiting patients at home. Some 41% of keyworkers met 'caseness' criteria on the GHQ12. Negative attitudes appeared to be independent of GHQ scores. CONCLUSIONS: Keyworkers expressed a number of positive and negative attitudes in relation to patient difficulties. Negative attitudes did not appear to be simply a feature of keyworker stress, however it is acknowledged that the sample size was small. Keyworkers' responses suggested a sense of personal failure when their patients were unwell or poorly engaged, despite patients being selected for assertive outreach on the basis of such difficulties. Recognition of negative attitudes may help in the improvement of training and supervision of staff members. PMID- 30282251 TI - Internal audit of attendances at a psychiatry outpatient clinic. AB - OBJECTIVE: This audit aimed to (a) systematically identify problems related to rates of attendance and non-attendance at one psychiatry outpatient clinic; (b) quantify these problems; (c) implement strategies to improve service delivery; and (d) re-audit after three months. METHODS: Specific standards were set in relation to patterns of attendance at the outpatient clinic. Audit was performed over two weeks; changes to practice were agreed and implemented for three months; re-audit was performed. RESULTS: The initial audit showed that (a) 93 people attended the clinic over two mornings with a non-attendance rate of 13.9%; (b) 30.1% of individuals who attended did not have an appointment; (c) 20.4% of attendances were 'inappropriate'; (d) 2.2% did not live in the clinic's catchment area. Based on these results, the clinic introduced a protocol for individuals who attended without appointment; a protocol for streamlining the provision of prescriptions; and a renewed emphasis on transferring the care of individuals not residing in the catchment area. Three months later, re-audit showed that (a) the number attending over two mornings decreased from 93 to 43, but the non attendance rate had not changed; (b) the proportion of individuals presenting without an appointment (9.3%) decreased significantly compared to the initial audit (30.1 %); (c) the proportion of 'inappropriate' attendances (9.3%) tended to decrease compared to the initial audit (20.4%) but this was not statistically significant; (d) there was no difference in the proportion of patients who did not live in the catchment area; these proportions were low in both the initial audit (2.2%) and re-audit (2.3%). CONCLUSIONS: A relatively simple audit such as this can result in a more efficient and appropriate delivery of outpatient mental health services. On this basis, there is a need to provide ongoing resources for further cycles of clinical audit in mental health services. PMID- 30282252 TI - Neonatal outcome following buprenorphine maintenance for opiate dependency. AB - Methadone substitution improves maternal and neonatal outcomes. However methadone induced neonatal abstinence syndrome (NAS) is common. Buprenorphine-exposed neonates may be at a lower risk of NAS. Currently in the Republic of Ireland, buprenorphine does not have a special licence for use in pregnancy. We describe here the history and neonatal outcomes of the first Irish woman maintained on buprenorphine during two pregnancies. Supervised urinanalysis on this mother between and throughout both pregnancies did not reveal any illicit drug use. She delivered two post-term babies of normal birth weight and length. The second infant required treatment for NAS for 21 days with morphine sulphate. Although the use of buprenorphine in pregnancy does not remove the possibility of NAS, neonatal outcomes of buprenorphine-maintained women compares favourably to methadone. As the use of buprenorphine becomes more established in Ireland, the management of buprenorphine-exposed neonates will become more common. PMID- 30282253 TI - Primary progressive aphasia presenting as possible conversion disorder. AB - We describe a case of primary progressive aphasia (PPA) in a 62 year old right handed Irish woman who had progressive speech and language difficulty over a period of six years. She continued to work for a remarkable length of time and lived independently managing all her activities of daily living. The case posed a diagnostic challenge because initial presentation was suggestive of a conversion disorder. She also displayed signs and symptoms which overlapped with a fronto temporal dementia and possibly early Alzheimer's disease. In our discussion, we explore the possible reasons for this overlap and the implication for psychiatrists. The need for adequate and sensitive investigations and a multi disciplinary approach cannot be overemphasised as PPA cases are easily missed depending on the stage at which the patient presents. PMID- 30282254 TI - Drug combination with bupropion: a case of southern comforts. AB - A patient with a 20-year history of dysthymia had been treated with a range of anti-depressants over a period of two decades. He had experienced no clinically significant symptomatic relief for 14 years until he was recommenced on fluoxetine, a drug which had been of limited benefit to him previously. He showed no improvement in motivation, chronic anergia or easy fatiguability. He commenced an anti-smoking agent, bupropion hydrochloride (Zyban), without informing his treating psychiatrist and following the manufacturers' instructions, took the drug for four weeks, while initially continuing to smoke. He failed to discontinue smoking. However, his energy, motivation and general sense of wellbeing improved markedly, to the extent that his friends and colleagues commented upon the change. Bupropion hydrochloride is a well-known anti depressant agent not currently licensed for use in Ireland. His combination of fluoxetine and bupropion has improved his functioning to its best level in 20 years. The improvement has been sustained for over six months. We examine the issues raised by this unusual combination, which I have termed 'southern comfort', in recognition of its geographical site of clinical impact. PMID- 30282255 TI - The lunatic asylums of Ireland 1825-1839. AB - OBJECTIVES: By the early 19th century the social manifestations of psychiatric disorder had become a matter of public and parliamentary pre-occupation in Ireland. This concern led to legislative provision for the establishment of a national system of district lunatic asylums. This paper describes some details of the early foundation of this system. METHOD: Examination of House of Commons papers on the lunatic asylums of Ireland 1835-1839. RESULTS: Details are presented concerning the activities, numbers of residents, admissions and costs of the 11 asylums in operation by 1839. CONCLUSIONS: By 1839 the operational, administrative and cultural characteristics of a national asylum system that would take another half century to complete and would extend well into the 20th century had been established.

AB - The goal of undertaking postgraduate training in psychiatry is to become a competent specialist, and the educational model under which one is trained and assessed is crucial in achieving this goal. Over the years, traditional training models have emphasised what trainees know, over a given period of time, with outcomes assessed mainly by simple recall of knowledge. While these traditional approaches have met with varying levels of success, they are less than optimal when the goal is to train individuals to perform specific, job-related skills. This recognition has led to a global move towards competency based training models where the focus of training and assessment is the mastery of specific knowledge and skills as well as the conduct of the doctor in day-to-day clinical situations. In this article, a general overview of competency-based training in psychiatry is followed by a review of recent developments in Ireland in a global context. PMID- 30282262 TI - The Suicide Risk Assessment and Management Manual (S-RAMM) Validation Study 1. AB - OBJECTIVE: There are validated tools for structured professional judgement of risk of violence, but few for risk of suicide. The Suicide Risk Assessment and Management Manual (S-RAMM) is a new structured professional judgement tool closely modelled on the HCR-20. This is the first validation study for the S RAMM. We measured inter-rater reliability, internal consistency, concurrent validity with another validated risk instrument (HCR-20) and with a measure of psychopathology (PANSS). We tested whether the tool could distinguish between groups of patients clinically assessed as at varying levels of risk of suicide or self harm. METHOD: Two researchers jointly interviewed 25 current in-patients for inter-rater reliability (Cohen's kappa) and internal consistency (Cronbach's alpha) and interviewed 81 of 83 current in-patients to assess whether the mean scores for different wards were significantly different (using ANOVA). Two other researchers made independent ratings of the HCR-20 and PANSS. RESULTS: Inter rater reliability was acceptable for all items (Cohen's kappa >0.5 for all but three items) and all sub-scale and total scores (Spearman correlations all >0.8). Internal consistency was high, (Cronbach's alpha all sub-scales >0.6). Scores stratified significantly with high scores for admission and intensive care units and progressively lower scores in rehabilitation and predischarge units. The HCR 20 historical and S-RAMM background scores did not correlate but the dynamic sub scales correlated significantly. PANSS scores also correlated significantly with S-RAMM scores. CONCLUSION: The S-RAMM has better than minimum acceptable characteristics for use as a clinical or research tool. Prospective studies of sensitivity and specificity are now required. PMID- 30282263 TI - Dialectical behaviour therapy in an Irish community mental health setting. AB - OBJECTIVES: Dialectical behaviour therapy (DBT) is a recommended treatment of patients with borderline personality disorder, yet there are few descriptions of the approach in public community mental health settings where the majority of such patients present. This study describes the development and evaluation of a DBT programme in an Irish setting. METHODS: The DBT programme was run over a six month period. Participants were assessed at baseline and post intervention with the following instruments: The Structured Clinical Interview for DSM III R personality disorders (SCID II), the clinical Outcomes in Routine Evaluation (CORE) and the symptom checklist 90 Revised (SCL-90-Revised). Inpatient bed usage was determined from case note review. RESULTS: Outcome data was available for eight subjects. Significant improvement (p < 0.005) was seen on all CORE subscales. SCL-90-R showed significant improvement (p < 0.05) on the global severity index and on the positive symptom distress index. A decrease in self harming behaviour was found. Subjects' inpatient bed days dropped from a mean of 58 in the year pre intervention to a mean of four days in the year post intervention. A novel finding was that 43% of subjects who originally fulfilled criteria for avoidant personality disorder no longer did so post intervention. CONCLUSIONS: The study found that DBT can be applied in a community mental health setting with benefits similar to more specialist settings. Significant difficulties were encountered in implementing the programme. The clinical implications are that specialist psychotherapy services need to be an integral part of psychiatric services to achieve better outcomes for patients with borderline personality disorder. PMID- 30282264 TI - Characteristics and progress of patients who receive inpatient rehabilitation services. AB - OBJECTIVES: To describe the characteristics and progress of the first 50 patients with severe and enduring mental illness who accessed inpatient rehabilitation services in Dublin North East Mental Health Service between 2001 and 2006. METHOD: Retrospective collection of data on the first 50 inpatients from case notes and staff interviews. Data included demographics, psychiatric history, results of rehabilitation interventions and assessment tools. The results were compiled and analysed using descriptive statistics. RESULTS: Fifty patients were identified. The majority were male (68%) with a diagnosis of paranoid schizophrenia (60%). The levels of co-morbid alcohol and drug misuse were 40% and 30% respectively. Histories of verbal/physical aggression were found in 92% and impulsive behaviour in 70%. The majority of patients had a past history of being detained under the Mental Treatment Act (1945). High levels of co-morbid physical health problems were identified. New long-stay (NLS) patients showed a trend towards requiring the shortest admissions prior to being ready for discharge to lower levels of support. CONCLUSION: One third of patients moved on to reside at lower support levels and accessed vocational training programmes following active inpatient rehabilitation interventions. However, there remained a cohort of patients who required prolonged inpatient admissions due to their high levels of disability. This study further highlights the need to ensure that a range of rehabilitation services from inpatient to supported community placement are provided to meet the needs of patients with severe and enduring mental illness with complex needs. PMID- 30282265 TI - Psycho-education of families in relation to their siblings' psychiatric illness. AB - OBJECTIVES: The aim of this study was to determine the extent of knowledge that family members of intellectually disabled individuals had in relation to their siblings' psychiatric illness. All siblings lived in residential intellectually disabled housing. METHOD: We evaluated on three occasions (before providing information about their sibling's psychiatric illness and treatment, and one and six months after providing this information) the families' understanding of their siblings' psychiatric illness. RESULTS: Initially families had a poor knowledge of their siblings' psychiatric illness and treatment, but this improved markedly after information was provided by a medical practitioner. This was a short-term effect, as at six months, families understanding had disimproved although not to pre-consultation levels. CONCLUSIONS: The provision of information to family members pertaining to their siblings' psychiatric diagnosis and treatment should be incorporated into the routine treatment of intellectually disabled individuals with a psychiatric illness. PMID- 30282266 TI - Comparison of referrals from primary and secondary care to CMHT psychologists. AB - OBJECTIVES: To explore whether (direct) referrals from GPs to two Community Mental Health Team (CMHT) clinical psychologists differed from those received from both 'Psychiatric' (eg. consultant psychiatrists) and 'Other' sources. METHOD: The two psychologists retrospectively examined and coded the case files of all clients who attended them during a 12-month period. The six measures used were diagnostic prevalence and groups, co-morbidity, chronicity, previous hospital admission and CMHT contact Separate cross-tabulations and chi squared tests were conducted for the various dependent variables to profile differences across the three referral sources. RESULTS: There was no difference in prevalence of Axis I disorders, co-morbidity and chronicity of disorders between 'GP' and 'Psychiatric' referrals to the two CMHT psychologists. However, although low in number, there were more eating and psychotic disorders among the 'Psychiatric' referrals, and more of these referrals had previous hospital admission and CMHT contact. CONCLUSIONS: 'GP' referrals were similar to 'Psychiatric' referrals on some measures but differed on others. Hence, as to whether an 'open access' model of (direct) referral to CMHT clinical psychologists lowers the clinical threshold for referrals depends on which measures are deemed most critical. Consistently applying a composite index of referral 'severity' could prevent the former. PMID- 30282267 TI - Childbirth-related post-traumatic stress disorder and its treatment. AB - The phenomenon of childbirth-related post-traumatic stress disorder (PTSD) has become more widely recognised in recent years following changes in 1994 to the DSM criteria regarding how a traumatic event was defined. Emerging literature has predominately focused on prevalence rates and risk factors associated with this condition and on the use of debriefing techniques as an attempt to reduce or prevent the development of postnatal PTSD. However, little is known about the efficacy of psychological interventions that have been used to treat PTSD among postnatal women. This review summarises the limited evidence supporting the use of such treatments and discusses the significant challenges in developing and implementing psychological interventions for childbirth-related PTSD. PMID- 30282268 TI - Barriers to care in the mental health service: who gets in - who gets out? AB - "People with mental health problems are particularly vulnerable to social exclusion" - Vision for Change. People with mental health problems are very vulnerable. However those with mental health problems who have additional social problems are even more vulnerable. Currently psychiatric services in Ireland are provided on a 'catchment area' basis, with a consultant psychiatrist leading a multi-disciplinary team providing a service to the population of a defined geographical area. These services comprise both outpatient and inpatient care, and there is significant regional variation in terms of both bed availability and multidisciplinary team staffing. Sub-specialities, with the exception of child psychiatry and psychiatry of old age, are often unavailable, particularly outside Dublin. In such cases, some additional duties (eg. liaison, rehabilitation, perinatal) are assumed by the local general adult services. However, the overall distribution of services is uneven. Instead of services being concentrated upon those areas of greatest need, the opposite is often the case, with the most deprived areas having the least services in terms of acute beds and community mental health teams per thousand people. These areas also have less psychological services and specialist services despite increased levels of mental illness. Within this vulnerable population there are a number of sub-groups who are even further marginalised, and for whom there are significant barriers both at point of contact with services and with accessing appropriate follow up services. These include the homeless, the ever-increasing cohort of migrants to this country, those in prison and children and adolescents. Stigma and discrimination are the greatest barriers to social inclusion, quality of life and recovery for people with mental illness.

AB - Status epilepticus (SE), both convulsive and nonconvulsive, is a rare adverse effect of electroconvulsive therapy (ECT). This case report describes SE post-ECT associated with central nervous system (CNS) metastatic melanoma and reviews pertinent literature. The authors recommend that when CNS pathology is suspected, pre-ECT neurology consultation, neuroimaging, and EEG all may be indicated. This is especially important for patients with histories of primary cancers, such as melanoma, that metastasise to the brain. PMID- 30282270 TI - Brain biopsy and a case of dementia that wasn't.

AB - Welcome to the first module in our Continuing Professional Development Section (CPD). CPD is now a key element in the clinical activity of all health professionals and a cornerstone of good clinical governance throughout mental health services. This section of the Irish Journal of Psychological Medicine will provide CPD modules dedicated to key topics in mental health care. In order to assist learning and self-assessment, multiple choice questions will be provided at the end of each module. This module and its multiple choice questions are available online on the website of the Irish Journal of Psychological Medicine (www.ijpm.org). The CPD policy of the College of Psychiatry of Ireland indicates that psychiatrists who participate in suitable online learning which fits the criteria for CPD may claim CPD points under the Personal CPD category (up to a maximum of 5 points per year). We are confident that this CPD Section of the Irish Journal of Psychological Medicine will prove to be a valuable resource for consultant psychiatrists, psychiatric trainees and all journal readers. We welcome feedback from readers and, especially, any suggestions for topics to be covered in future CPD modules. Suggestions should be emailed to: psychological@medmedia.ie. PMID- 30282273 TI - Electroconvulsive therapy, capacity and the law in Ireland. AB - The Mental Health Act (MHA) 2001 has major implications for treating patients with electroconvulsive therapy (ECT), especially as those referred for treatment are among the most severely ill and often lose capacity. Under the MHA 2001, a person may only be treated without consent if they are an involuntary patient. However, there is no provision in the Act for treating voluntary inpatients whose mental state has deteriorated but who do not seek to leave hospital. Such people may lack capacity to make treatment decisions but be passively compliant. The Wards of Court system is currently the only legal recourse but has been criticised by the Law Reform Commission and is unwieldy. Further legislation governing treatment of people lacking capacity to consent to ECT or withhold consent is required to protect and advance treatment of all concerned. PMID- 30282274 TI - Factors that influence patients' attitudes to antipsychotic medication. AB - OBJECTIVE: The aim of this study was to investigate the attitudes to medication in relation to insight, purpose in life, symptoms and sociodemographic factors among a cohort of stable patients with a diagnosis of schizophrenia and schizoaffective disorder. METHOD: We included 70 patients with a diagnosis of schizophrenia and schizoaffective disorder attending a Dublin suburban mental health service. All participants were 18 years or older and were excluded if they had a learning disability, acquired brain injury resulting in unconsciousness, and psychosis secondary to a general medical condition or illicit substance misuse. All participants were given self report questionnaires which included Drug Attitude Inventory (DAI-30), Birchwood Insight Scale, and Purpose in Life test. Symptoms were assessed using the Scale for Assessment of Positive and Negative symptoms. All data was analysed using the Statistical Package for the Social Sciences. RESULTS: We found that 86% (n = 60) of the participants had positive attitudes to medication, and 82% (n = 58) had good insight into their illness. Only 27% (n = 19) were found to have a definite purpose in life. There was a significant negative relationship between attitudes to medication and delusions (r = -0.25, n = 70, p < 0.05) and a significant positive relationship between insight and attitudes to medication (r = 0.0.28, n = 70, p < 0.05). CONCLUSION: Many factors are involved in the multifaceted issue of attitudes to medication. Researchers must realise that these factors do not remain constant and may change with time and over the course of illness and treatment. PMID- 30282275 TI - Psychopathology, insight and compliance in schizophrenia. AB - : Abstraact Objective: A four-week longitudinal study was conducted to assess the relationship between insight, psychopathology and treatment compliance in schizophrenia. METHOD: The study was conducted using Insight and Treatment Attitude Questionnaire (ITAQ), Positive and Negative Syndrome Scale (PANSS) and Medication Adherence Rating Scale (MARS). The sample comprised 50 patients with schizophrenia diagnosed according to research criteria of the International Classification of Diseases (ICD-10), with a mean duration of illness of 5.32 years. RESULTS: Substantial psychopathology was observed at intake and it improved significantly at the end of four weeks. Similar changes were observed in the score of insight and of compliance over four weeks. The insight and the compliance were positively correlated to each other at the beginning and at the end of four weeks. Both of these were negatively correlated with psychopathology scores on both occasions. CONCLUSION: Insight and psychopathology remain important determinants of treatment compliance in schizophrenia over short term and long term follow up. PMID- 30282276 TI - Psychiatric illness and driving: Irish psychiatrists' documentation practices. AB - OBJECTIVE: Psychiatric illness and the use of psychotropic medication are recognised as factors that may impair driving ability. Clinicians in the UK have a legal duty to advise patients on the effects of illness and prescribed medication on driving ability. Although clinicians in Ireland have no equivalent legal obligations, good medical practice suggests that doctors should be aware of whether patients are active drivers, and issue appropriate advice, supported by adequate documentation in clinical notes. METHOD: The initial phase of the study analysed 44 outpatient records and 48 discharge records to ascertain the level of documentation regarding driving status, and advice given to patients regarding the effect of illness or medication on driving ability. The second phase involved distribution of an anonymous questionnaire to 18 psychiatrists employed in the acute psychiatric unit setting. RESULTS: Although there was minimal documentation regarding the potential effect of illness on driving ability, more than 50% of case notes revealed documented advice to patients regarding side-effects of medication and driving ability. Over 50% of case notes contained advice about medication compliance, but none contained cautionary advice about operating machinery. All psychiatrists admitted not being aware of the driving status of every patient they reviewed. Over 50% admitted to advising patients of the effect of illness or medication on driving ability, but fewer reported documenting this advice on every occasion. All psychiatrists reported that they would benefit from training in this area. CONCLUSION: This study suggests that there is underdocumentation of advice given to patients regarding the effect of their symptoms or medication on driving ability. Clinicians need to improve their awareness of patients' driving status, in addition to receiving training on what their responsibilities are in this regard. PMID- 30282277 TI - Non-attendance at new appointments at St James's Child Guidance Clinic. AB - OBJECTIVE: This study aimed to examine non-attendance rates at new appointments at St James's Child Guidance Clinic. METHOD: The sample consisted of all new referrals to St. James's Child Guidance Clinic in one calendar year (2004). Data was collected retrospectively from an electronic patient information system (Pinpoint), the new patient-referral logbook, referral letters, the appointment diary, and from clinical records. RESULTS: There were 260 new referrals to St James's Child Guidance Clinic in 2004. Out of the 260 children and adolescents granted a new appointment, 34 (13.07%) who failed to keep their appointment were identified. All patients granted an urgent appointment did attend. CONCLUSIONS: Non-attendance rates at new assessment in St James's Child Guidance Clinic were slightly lower than those reported in other studies. The implemented evidence based strategies to reduce non-attendance rates could explain the relatively low non-attendance rate at new assessment. PMID- 30282278 TI - Consultant psychiatrists' experiences and attitudes following the introduction of the Mental Health Act 2001: a national survey. AB - OBJECTIVE: This study explored the attitudes and experiences of consultant psychiatrists regarding the Mental Health Act 2001. METHOD: A postal survey was distributed to all consultant psychiatrists (n=238) in the Republic of Ireland. All specialties were included except Child and Adolescent Psychiatry. RESULTS: A response rate of 70% was achieved. Care of involuntarily admitted patients has improved according to 32%, but 48% found that the care of voluntary patients has deteriorated. Sixty-nine per cent of consultant psychiatrists acknowledge that involuntarily admitted patients are being changed to voluntary early to avoid a tribunal, and 21 % believe it occurs in over 40% of cases. Fourteen per cent of consultant psychiatrists have re-admitted a patient involuntarily immediately after a tribunal revoked the original Involuntary Order. Junior doctors' training by consultant psychiatrists has been reduced in 57% of placements as a result of the increased demands of the MHA 2001. Eighty-seven per cent report an increase in their on call service workload but only 23% report a sufficient increase in the number of consultants within their service. While 78% agree that patients should not be admitted involuntarily solely on the grounds that the person is suffering from a personality disorder, 58% feel that there is a risk in such patients not being involuntarily admitted in situations in which it is clinically necessary. Fifty-six per cent feel that there is a similar risk in patients with a diagnosis of substance misuse. CONCLUSION: Resources required to implement the Mental Health Act 2001 have not been sufficient leading to poorer quality of service and negatively affecting NCHDs training. PMID- 30282279 TI - Drug users' failure to modify alcohol consumption in response to hepatitis C. AB - OBJECTIVE: To measure (a) the prevalence of problem drinking in a population of methadone-treated drug users, (b) independent associations with problem drinking, (c) the effect of hepatitis C status on drinking behaviour, (d) the knowledge of drug users of their hepatitis C status and their perception of their drinking behaviour and (e) the attitude of drug users to the effect of alcohol on hepatitis C virus (HCV) related disease. METHOD: A cross sectional survey of 130 drug users in treatment at the National Drug Treatment Centre, Dublin was carried out. A questionnaire incorporated the Alcohol Use Disorders Identification Test (AUDIT), and data were collected on sociodemographics, drug use history, perceived HCV status and drinking behaviour, and attitudes to the impact of drinking on HCV related disease. Hepatitis serology and drug urine data were collected from clinical records. RESULTS: The prevalence of problem drinking was 41% (95% CI 33-51%). Unstable accommodation, older age, male gender and longer duration of heroin use were independent associations with being a problem drinker. There was no significant difference in the prevalence of problem drinking across HCV status. Knowledge of HCV status was accurate, however 35% of those identified as AUDIT cases failed to recognise their problem drinking. CONCLUSION: HCV infection among Irish drug users is compounded by a high prevalence of problem drinking with drug users failing to modify their drinking in response. Incorrect perception of problem drinking status could be a barrier to addressing this potentially remediable risk factor. PMID- 30282280 TI - Insight in mental illness: an educational review. AB - Insight is an elusive concept in psychiatry with a long history of divergent definitions and methods of measurements. Although insight was previously presumed to be a binary construct that an individual could possess or lack, there is an emerging consensus that insight is a multi-dimensional construct consisting of a spectrum of phenomena. Over recent years there has been increasing interest in the topic of insight, especially in relation to psychotic disorders where insight is frequently diminished. In this educational review we will discuss the history associated with the construct of insight, current theories in relation to insight, the association of insight with clinical symptoms and prognosis with particular reference to psychosis, the various methods of measuring insight, the aetiology of insight and present deficiencies in our understanding of insight. PMID- 30282281 TI - Mental capacity: legislation and medical treatment decisions in Ireland. AB - This paper examines mental capacity legislation in Ireland and its implications for medical treatment decisions for people whose capacities are believed to be impaired. It draws on inferences from case laws and legislations in other jurisdictions and concludes that there is an urgent need for the enactment of appropriate mental capacity legislation in Ireland.

AB - BACKGROUND: Most children who have Asperger's Syndrome (AS) are not identified until early school age, when social difficulties with other children become evident. Consequently, primary school teachers have an important role to play both in the recognition and management of the condition. OBJECTIVES: Our study sought to examine the perception of primary school teachers regarding the recognition and management of AS. METHODS: A structured questionnaire on the recognition and management of AS was circulated to all 90 primary school principals in the Fingal County of Dublin for them to copy and distribute to teachers in their schools for completion. Self-addressed envelopes were provided to each principal for the return of completed questionnaires. RESULTS: Three hundred and forty-three completed questionnaires were returned by 54 out of the 90 school principals. Fifty-eight per cent of respondents reported that they had ever taught a child with the condition and 49% reported that recognition and management of emotional and behavioural disorders was covered in their undergraduate training. Some 78.4% said that they would recognise the symptoms of AS in a child, with those who had training on the recognition and management of emotional and behavioural disorders being more likely to report that they would recognise such symptoms while 71.1% said children with AS should be taught in mainstream classes. However, 77.3% did not think mainstream schools are presently adequately resourced to cater for children with AS. Some 96.2% said they would like to receive in-service training from the Child and Adolescent Mental Health Services on the detection and management of children with AS. CONCLUSION: There is a need for formal in-service training for all primary school teachers in the recognition and management of children with Pervasive Developmental Disorders (PDD). The recognition and management of children with PDD should also be included in the curriculum of all undergraduate teacher training institutions in Ireland. PMID- 30282288 TI - Deliberate self-harm (DSH) out of hour's presentations. AB - OBJECTIVE: To establish time of presentation to paediatric accident and emergency (A&E) services of children with deliberate self-harm (DSH). METHOD: All children presenting to an acute paediatric hospital with DSH or suicidal ideation between 1993-2003 were identified and time of presentation collected from their case notes. RESULTS: Of the 172 children where the actual time of presentation was recorded, the majority of children - 137 (80%) presented to the hospital outside of the 'normal working hours' of 9am-5pm, Monday - Friday. These children represent an at-risk group, and were more likely to have consumed alcohol, to have made a suicide attempt, and to have a family history of psychiatric illness than children presenting with "normal working hours". CONCLUSION: DSH in young people is a significant public health problem in Ireland and is a major risk factor for completed suicide. Access to an out of hours on-call Child and Adolescent Psychiatry (CAP) services is essential if these children are to have a mental health assessment, as recommended by the Royal College of Psychiatry and National Institute of Clinical Excellence. These services need to be urgently developed. PMID- 30282289 TI - Prevalence and clinical correlates of depression in the acute phase of first episode schizophrenia. AB - BACKGROUND: Reported rates of depression in schizophrenia vary considerably. OBJECTIVE: To measure the prevalence of depression in a first episode sample of people with schizophrenia. METHODS: All referrals with a first episode of schizophrenia diagnosed using SCID interviews were assessed pre-discharge and again six months later. We used the Calgary Depression Scale for Schizophrenia (CDSS) and Positive and Negative Syndrome Scale (PANSS) to assess the severity of symptoms. RESULTS: Pre-discharge, 10.4% of the sample met CDSS criteria for depression. According to the PANSS depression (PANSS -D) subscale, 3% of patients were depressed, with a mean score of 7.48 (SD = 2.97). Only 3% of patients pre discharge were found to be depressed on both the CDSS and the PANSS-D. Six months later 6.5% were depressed according to the CDSS. However none reached depression criteria according to the PANSS-D. The CDSS correlated with PANSS-D both pre discharge and at follow-up. Feelings of depression and self-deprecation were the most common symptoms at baseline and follow-up. The CDSS was unrelated to negative symptoms at both stages. A lifetime history of alcohol abuse increased the risk for depression. CONCLUSION: Rates of depression in this sample were low. The CDSS appears to discriminate between depression and negative symptoms. Like the general population, alcohol misuse is a risk factor for depression in first episode schizophrenia. PMID- 30282290 TI - Medication adherence and knowledge in older patients. AB - OBJECTIVES: To assess the degree to which a sample of older individuals - who are engaged with psychiatric services - are knowledgeable about their medication and the reason for its prescription; to assess the degree to which these patients adhere to what is prescribed. METHODS: Convenience sample of 24 patients over 65 years old, under the care of psychiatric services for Later Life, included. Patients who scored < 23 on Mini-mental State Examination were excluded. A questionnaire was administered which evaluated patients' knowledge of the names of, and reasons for, all prescription medications. Adherence rates were measured. Comparisons were made regarding to self-reported adherence rates and medication knowledge. These were based on diagnosis, age, number of medications prescribed and the presence or absence of sensory impairment. RESULTS: The median percentage of medication names recalled was 60%. A total of 25% of patients reported having some problem with adherence. No patient with a diagnosis of dementia was able to recall the names of, or reasons for, all medications prescribed. Patients with depression and dementia were as likely to be fully adherent as the total sample. Patients (a) aged 78 years or more and (b) those who were on more than six medications - were less knowledgeable about and less likely to adhere to prescribed drug regimens. We did not identify an association between reduced visual acuity and reduced medication adherence Conclusion: Patients require ongoing education concerning all aspects of medication, especially the reasons for prescription. Older patients and those receiving more complex regimens may be at particular risk of adherence problems. PMID- 30282291 TI - Association between antipsychotic medication and venous thromboembolism. AB - OBJECTIVE: This study aims to identify and review available evidence in the literature to determine the strength of association between antipsychotic medications and thromboembolism as an adverse effect. METHOD: Electronic databases were searched for evidence. RESULTS: A total of 15 case reports, 14 case series, two observational studies and three case-control studies were found in the literature. Two case control studies found significantly increased risk of venous thromboembolism (OR 13.3 and 7.1 respectively). The risk was high for low potency antipsychotics. Studies were critically appraised to determine the strength of evidence. CONCLUSION: The studies reviewed indicate a significant association between antipsychotics and venous thromboembolism. Patients using the antipsychotics and those who prescribe them should be aware of this association. PMID- 30282292 TI - Reducing the revolving door phenomenon. AB - OBJECTIVES: De-institutionalisation and the expansion of community services have resulted in a reduction in the number of inpatient admissions in Ireland having fallen by 31% between 1986 and 2006. However, despite this, readmissions continue to account for over 70% of all admissions. The policy document A Vision for Change identified many shortcomings in the current model of provision of mental health services, making recommendations for the future development of community based services with emphasis on outreach components such as homecare, crisis intervention and assertive outreach approaches. These recommendations are reviewed in relation to readmissions and the impact they may have on reducing the revolving door phenomenon. METHOD: Three main intervention programmes essential to the delivery of an effective community-based service outlined and recommended by A Vision for Change, along with other pertinent factors, are discussed in relation to how they might reduce readmissions in Ireland. A series of Pearson correlations between Irish inpatient admissions rates and rates of outpatient attendances and provision of community mental health services are carried out and examined to explain possible relationships between increasing/decreasing admission rates and provision/attendances at community services. International literature is reviewed to determine the effectiveness of these intervention programmes in reducing admissions and readmissions and their relevance to the Irish situation is discussed. CONCLUSIONS: Whilst A Vision for Change goes a long way towards advocating a more person-centred, recovery oriented and integrated model of service delivery, it is apparent from the consistently high proportion of readmissions in Ireland that there are still many shortcomings in service provision. The availability of specialised community-based programmes of care is as yet relatively uncommon in Ireland and uneven in geographical distribution. A considerable improvement in their provision, quantitatively and qualitatively, is required to impact on the revolving door phenomenon. In addition a re configuration of existing catchment populations is required if they are to be successfully introduced and expanded. PMID- 30282293 TI - The Myth of Mental Illness: 50 years after publication: What does it mean today? AB - In 1960, Thomas Szasz published The Myth of Mental Illness, arguing that mental illness was a harmful myth without a demonstrated basis in biological pathology and with the potential to damage current conceptions of human responsibility. Szasz's arguments have provoked considerable controversy over the past five decades. This paper marks the 50th anniversary of The Myth of Mental Illness by providing commentaries on its contemporary relevance from the perspectives of a range of stakeholders, including a consultant psychiatrist, psychiatric patient, professor of philosophy and mental health, a specialist registrar in psychiatry, and a lecturer in psychiatry. This paper also includes responses by Professor Thomas Szasz. Szasz's arguments contain echoes of positivism, Cartesian dualism, and Enlightenment philosophy, and point to a genuine complexity at the heart of contemporary psychiatric taxonomy: how is 'mental illness' to be defined? And by whom? The basis of Szasz's doubts about the similarities between mental and physical illnesses remain apparent today, but it remains equally apparent that a failure to describe a biological basis for mental illness does not mean there is none (eg. consider the position of epilepsy, prior to the electroencephalogram). Psychiatry would probably be different today if The Myth of Mental Illness had not been written, but possibly not in the ways that Szasz might imagine: does the relentless incarceration of individuals with 'mental illness' in the world's prisons represent the logical culmination of Szaszian thought? In response, Professor Szasz emphasises his views that "mental illness" differs fundamentally from physical illness, and that the principal habits the term 'mental illness' involves are stigmatisation, deprivation of liberty (civil commitment) and deprivation of the right to trial for alleged criminal conduct (the insanity defence). He links the incarceration of the mentally ill with the policy of de institutionalisation (which he opposes) and states that, in his view, the only limitation his work imposes on human activities are limitations on practices which are conventionally and conveniently labelled 'psychiatric abuses'. Clearly, there remains a diversity of views about the merits of Szasz's arguments, but there is little diminution in his ability to provoke an argument. PMID- 30282295 TI - Tardive dyskinesia on low dose risperidone. AB - Tardive dyskinesia is a neurological disorder characterised by involuntary and purposeless movements affecting any part of the body. These movements typically occur in the oro-facial area and the patient is usually unaware of them. There are inconsistent findings in the literature on the risk factors for developing tardive dyskinesia. Nevertheless, previous reports indicate that tardive dyskinesia is more common in female patients, patients with a history of alcohol and substance misuse, affective disorders, and intellectual disability. The dose, class and duration of antipsychotic nmedication may also be independent risk factors. We report on the case of a patient who developed tardive dyskinesia on a low dose of the second generation antipsychotic risperidone. PMID- 30282294 TI - Absinthe and suicidality. AB - Absinthe is an alcoholic drink which is becoming more widely consumed after being banned for many decades. An association between absinthe use and psychiatric symptoms, ranging from impairment of concentration to marked hallucinations and seizures, has been suggested, but evidence remains unclear. Thujone, identified as a possible psychoactive ingredient, has recently been implicated in absinthe's putative neuropsychiatric effects. This report presents a case where acute suicidality emerged during absinthe consumption; possible neurobiological aetiological mechanisms and the history of absinthe use and associated adverse effects are reviewed. PMID- 30282296 TI - Cannabis and hyperemesis. AB - The adverse effects of marijuana are well documented, as well as its positive therapeutic uses. Cannabis has traditionally been associated with an antiemetic action following acute ingestion and synthetic cannabinoids have an established use as antiemetics for chemotherapy induced nausea. However, there has been limited recognition of chronic cannabis use as a cause of cyclic vomiting syndrome. Cannabinoid hyperemesis was first identified by Allen er al in 2004. Compulsive bathing was also described as part of the clinical picture. This same syndrome has been confirmed a number of times in the medical literature in the interim. The condition has, to our knowledge, never been reported, in a psychiatric patient. PMID- 30282298 TI - New long-stay patients in Irish psychiatric inpatient services.

PMID- 30282299 TI - Impact of new long-stay patients on Irish psychiatric inpatient services. PMID- 30282301 TI - Adherence in psychiatry. AB - The word 'adherence' refers to the provision of consistent support (eg. for a political party or religion) or the act of holding particular elements together (eg. in constructing a building). In the medical context, adherence refers to the extent to which patients take their medications as prescribed. While the terminology related to medical adherence has changed significantly over the past two millennia, the core issue has not. Most recently, the term 'adherence' has replaced the term 'compliance', although it still jostles with 'concordance' in a growing literature which focuses now, as always, on one key question: why do so many people seek treatment for illness but then decide not to take their prescribed medication? This is an important question, both in terms of public health and societal cost: in the US, up to 50% of patients do not take their prescribed medications, resulting in additional healthcare costs of $290 billion per year. The greatest cost of non-adherence, however, relates to prolonged illness, increased rates of relapse and reduced wellness. PMID- 30282302 TI - Is there a role for suicide research in modern Ireland? AB - Suicide is a major public health issue of global concern. It is the leading cause of death in young Irish men, marking suicide and suicidal behaviour as important topics for clinical epidemiology and public health research. Ireland has a statutory obligation from the "Reach Out" policy document to "systematically plan research into suicidal behaviour to address deficits in our knowledge" (pp. 50). Suicide is undoubtedly a complex phenomenon and therefore one which requires advanced methods of investigation and innovative approaches to research the factors underpinning suicide in modern Ireland, the development and evaluation of prevention strategies and the informing of evidence-based policy. PMID- 30282303 TI - The Suicide Risk Assessment and Management Manual (S-RAMM) Validation Study II. AB - OBJECTIVES: Structured professional judgement is now the most widely accepted approach to clinical risk assessment and risk management. The Suicide Risk Assessment and Management Manual (S-RAMM) is a new structured professional judgement tool closely modelled on the HCR-20. This is the first prospective validation study for this instrument. METHODS: Two post-membership registrars jointly interviewed 81 of 83 current inpatients to rate the S-RAMM. Two assistant psychologists independently rated the HCR-20, GAF and PANSS. All incidents of self-harm, attempted suicide, suicide and violence to others were collated from hospital reporting of critical incidents over the next six months supplemented by examination of other records. RESULTS: For combined self-harm and suicide outcomes, the S-RAMM total score using the receiver operating characteristic had an area under the curve AUC=0.89, (95% CI 0.79 to 0.99). The S-RAMM performed as well for the prediction of self-harm and suicide as the HCR-20 did for violence, and better than measures of mental state (PANSS total score) and global function (GAF). CONCLUSIONS: The S-RAMM has better than minimum acceptable characteristics for use as a clinical or research tool for suicide risk assessment, and performs almost as well as the HCR-20 does for violence. Further prospective studies are now required, in other populations. PMID- 30282304 TI - Deliberate self-harm in young people: attendance at a paediatric emergency department. AB - OBJECTIVES: Deliberate self-harm (DSH) is the strongest predictor of suicidal behaviour. This retrospective study reviewed all DSH presentations to our Paediatric Emergency Department between 2002-2006. METHOD: Using database and medical records we profiled these presentations. Data was coded and statistically analysed. RESULTS: There were 253 DSH attendances. Twenty-four percent were living in care, 15% were under 12 years and 14% presented more than once. Overdoses (61%) were more common than cutting (16%) and 56% had a psychiatric condition. CONCLUSIONS: DSH presents an ongoing challenge to child and adolescent mental health services and those working in suicide prevention. Identifying the characteristics of these young people is essential to providing appropriate treatment for this high-risk group. PMID- 30282305 TI - The distribution of wellbeing in Ireland. AB - OBJECTIVES: There is a substantial knowledge gap about the distribution of mental health in community populations. The European Social Survey is particularly useful as it contains information on over 40,000 individuals, including 2,286 Irish adults. The objective of this study is to conduct a large scale statistical analysis to examine the distribution and determinants of mental wellbeing in a large representative sample of the Irish population. METHOD: Analysis of the European Social Survey using robust multiple linear and non-linear regression techniques. The data-set contains WHO-Five scores and subjective wellbeing for a sample of 2,286 Irish people interviewed in their homes in 2005. RESULTS: Ireland has the second highest average WHO-Five score among the 22 countries in the European Social Survey. Multiple linear regression analysis across the distribution of WHO-Five reveals a wellbeing gradient largely related to education and social capital variables. A probit model examining the determinants of vulnerability to psychiatric morbidity reveals that a similar set of factors predict scores below the threshold point on the WHO-Five scale. CONCLUSIONS: The results are consistent with marked differences in mental wellbeing across education levels and variables relating to social capital factors. Such indicators provide a useful index for policy-makers and researchers. However, much further work is needed to identify causal mechanisms generating observed differences in mental health across different socioeconomic groups. PMID- 30282306 TI - Client satisfaction among outpatients attending an Irish community mental health service. AB - OBJECTIVES: To assess patient satisfaction with mental health services. Client satisfaction with mental health services is attracting increasing attention and is now considered a key outcome variable in evaluating mental health services. The Quality Framework (Mental Health Commission (MHC)), and Vision for Change (VFC) support such evaluation. However, there are no published quantitative data from Irish users of a community mental health service. METHOD: We invited outpatients attending a Dublin community mental health service to complete a standardised self-report instrument (Client Satisfaction Questionnaire, CSQ-8) and provide qualitative feedback. RESULTS: Of the seventy-nine respondents, 80% report they were 'satisfied' or 'very satisfied' with the service. However, they were critical of; access to, operation of, and communication with the mental health services. CONCLUSIONS: Although satisfied, when given the opportunity to comment, service users can be critical of aspects of the service they receive. Only using quantitative evaluation of outpatient client satisfaction levels may fail to capture important consumer suggestions for service development. Recent recommendations and upcoming changes would address a number of the criticisms of mental health services identified in this study. PMID- 30282307 TI - Neuropsychology and its relevance to clinical psychology in the non-specialist adult mental health setting. AB - OBJECTIVES: This study aims to investigate the prevalence of neuropsychological disorders in a non-specialist clinical psychology service in adult mental health service and also to explore the existence of neuropsychological symptoms in those subjects having psychiatric disorders. METHOD: The yearly data of new referrals from the psychology register and record files of the patients was collected for this purpose and subsequently analysed. The two content scales of MMPI-2, ie. HEA2 and HEA3 were administered and scored. RESULTS: The results indicate that neuropsychological disorders were the second major referral source during this period and a significant difference (p = 0.001) was found between the scores of HEA-2 and HEA-3, which suggest that the subjects reported more neuropsychological symptoms than symptoms of general health concern during their initial routine psychological assessment. CONCLUSION: There is consistency in our findings regarding the questions raised in this study which indicates a prevalence of neuropsychological disorders in adult mental health settings. It also indicates a high rate of neurological symptoms in psychiatric patients with psychiatric disorders.

AB - OBJECTIVES: The most recent census of psychiatric inpatients (Daly and Walsh, 2006) examined the decline of the long-stay population (both new and old long stay) from 1963 to 2006. The aim of the present study was to identify new long stay patients (patients in hospital between one and five years) in the 2006 psychiatric in-patient census and follow them up one year later to determine the number remaining as inpatients, ie. not having been discharged Methods: New long stay patients were extracted from the 2006 psychiatric inpatient census data base and were followed up one year later. RESULTS: Sixty-eight per cent (315/460) of new longstay patients on 31/03/06 were still resident in units and hospitals one year later on 31/03/07, the majority in psychiatric hospitals Forty-two per cent (133/315) of patients had a primary diagnosis of schizophrenia, 13% (40/315) of depressive disorder, 11% (33/315) of organic mental disorder and 8% of intellectual disability (24/315). The number of new long-stay patients discharged or who died showed a sharp decline on previous years. CONCLUSIONS: Unless current services are improved and extended as advocated in A Vision for Change, it will be a number of years before this population leaves psychiatric hospitals and such hospitals can close because of the lack of suitable alternatives. In accordance with policy recommendations, the continuing requirement for the development of specialised rehabilitation services to cater for the broad needs of those who remain in psychiatric hospitals is of the utmost importance. PMID- 30282309 TI - CBT for adolescent pathological gambling - lessons from adult research. AB - OBJECTIVES: Features of gambling, particularly among young people have changed over the past decade and, while there are no data from Ireland, there are suggestions from those working in the field that pathological gambling is increasing among adolescents. Relatively little is known about the effective treatment of pathological gambling in adolescents. This paper aims to review research in cognitive behavioural treatments with a view to their application in adolescents. Research among adolescence is given prominence when this is available. METHODS: The methodology comprised a literature search of Medline, Psycinfo, and EMBASE databases, using the search terms: 'cognitive behavioural therapy'; 'gambling; 'psychology'; 'epidemiology'; 'adolescent'; 'motivation'; 'effectiveness'; 'outcome'; 'relapse'; and 'internet'. In addition, a hand search of Clinical Psychological Reviews, Journal of Gambling Studies, Addiction, Psychology of Addictive Behaviors, and International Gambling Studies (1997-2007) was performed. RESULTS: A total of 23 studies comprising various cognitive and behavioural approaches were identified, all but three of them confined to adult subjects. Study methodology and quality varied greatly, with many case studies or small case series, and only three randomised control trials. None used an intention-to-treat analysis, and there was little long-term follow-up. Almost ail indicated, with more or less evidence, that cognitive behavioural strategies might be beneficial. CONCLUSIONS: Many varieties and modifications of cognitive behavioural therapy have been applied to pathological gambling, though there are few studies of any psychological treatments for adolescent gamblers. Methodological problems surround much of the research. Notwithstanding these reservations cognitive behavioural approaches seem to offer promise in managing this serious problem. PMID- 30282310 TI - Clozapine induced myocarditis: a case report and literature review. AB - Clozapine, the drug of choice for treatment resistant schizophrenia, has a range of serious cardiac side-effects. This paper describes a fatal case of myocarditis in a 48 year old man four weeks after starting clozapine. In particular, this case illustrates how incipient the disorder can be and the need for a high level of suspicion. Difficulties in diagnosing clozapine induced myocarditis and ways to minimise its risk are also discussed. PMID- 30282311 TI - Pulmonary embolism secondary to clozapine therapy. AB - Clozapine is an atypical antipsychotic indicated for paranoid schizophrenia (treatment resistant type). However its use has been limited by the well established association with neutropenia and agranulocytosis. It has also been suggested that clozapine therapy is associated with other serious adverse effects such as fatal myocarditis or cardiomyopathy.

PMID- 30282317 TI - Copper radiopharmaceuticals for theranostic applications. AB - The growing advancement in nuclear medicine challenges researchers from several different fields to integrate imaging and therapeutic modalities in a theranostic radiopharmaceutical, which can be defined as a molecular entity with readily replaceable radioisotope to provide easy switch between diagnostic and therapeutic applications for efficient and patient-friendly treatment of diseases. For such a reason, the diagnostic and therapeutic potential of all five medical radionuclides of copper have thoroughly been investigated as they boost the hope for development of successful radiotheranostics. To facilitate the mutual understanding between all different specialists working on this multidisciplinary field, we summarized the recent updates in copper-based nuclear medicine, with specific attention to the potential theranostic applications. Thereby, this review paper is focused on the current achievements in the copper related complementary fields, such as synthetic and nuclear chemistry, biological assessment of radiopharmaceuticals, design and development of nanomaterials for multimodal theranostic implications. This work includes: i) description of available copper radionuclide production methods; ii) analyses of the synthetic strategies for development of improved copper radiopharmaceuticals; iii) summary of reported clinical data and recent preclinical studies from the last five years on biological applicability of copper radiopharmaceuticals; and iv) illustration of some sophisticated multimodal nanotheranostic agents that comprise several imaging and therapeutic modalities. Significant advancement can be seen in the synthetic procedures, which enables the broader implication of pretargeting approaches via bioorthogonal click reactions, as well as in the nanotechnology methods for biomimetic construction of biocompatible multimodal copper theranostics. All this gives the hope that personalized treatment of various diseases can be achieved by copper theranostics in the near future. PMID- 30282319 TI - A comprehensive review on xanthone derivatives as alpha-glucosidase inhibitors. AB - alpha-Glucosidase plays an important role in carbohydrate metabolism and is therefore an attractive therapeutic target for the treatment of diabetes, obesity and other related complications. In the last two decades, considerable interest has been given to natural and synthetic xanthone derivatives in this field of research. Herein, a comprehensive review of the literature on xanthones as inhibitors of alpha-glucosidase activity, their mechanism of action, experimental procedures and structure-activity relationships have been reviewed for more than 280 analogs. With this overview we intend to motivate and challenge researchers (e.g. chemistry, biology, pharmaceutical and medicinal areas) for the design of novel xanthones as multipotent drugs and exploit the properties of this class of compounds in the management of diabetic complications. PMID- 30282318 TI - Synthesis and structure-activity relationship studies of cruzain and rhodesain inhibitors. AB - Chagas disease and Human African trypanosomiasis (HAT) are important public health issues in Latin American and sub-Saharan African countries, respectively, and are responsible for a significant number of deaths. The drugs currently used to treat Chagas disease and HAT present efficacy, toxicity, and/or resistance issues; thus, there is a clear need for the discovery of novel targets and drug candidates to combat these diseases. In recent years, much effort has been made to find inhibitors of cruzain and rhodesain, which are promising targets for the design of novel trypanocidal compounds, since they are essential for parasite survival. Many reviews covering the design of novel cruzain and rhodesain inhibitors have been published; however, none have focused on the chemistry of the inhibitors. Thus, in the present work we reviewed the synthetic strategies and routes for the preparation of relevant classes of cruzain and rhodesain inhibitors. Perhaps the most important are the vinyl sulfone derivatives, and a very efficient synthetic strategy based on the Horner-Wadsworth-Emmons reaction was developed to yield these compounds. Modern approaches such as the asymmetric addition of substituted ethynyllithium to N-sulfinyl ketimines were used to produce the chiral alkynes that were employed in the preparation of important chiral triazole derivatives (potent cruzain inhibitors) and chiral HPLC resolution was used for the preparation of enantiopure 3-bromoisoxazoline derivatives (rhodesain inhibitors). Moreover, we also highlight the most important activity results and updated SAR results. PMID- 30282320 TI - Dimetallic Ru(II) arene complexes appended on bis-salicylaldimine induce cancer cell death and suppress invasion via p53-dependent signaling. AB - A series of bis-salicylaldimine ligands bearing two ON-donor functions were reacted with dichloro(p-cymene)ruthenium(II) dimer in the presence of base (NaOAc) and a series of four dimetallic Ru(II) arene complexes (Ru(p cymene))2(bis-salicylaldimine)Cl2 (C1C4) were prepared. These complexes were obtained in excellent isolated yields and characterized in detail by using different spectroscopic techniques. The structure of C1 was also determined in solid state by single crystal X-ray analysis. These complexes were studied for their cytotoxic effect against three different types of human cancer cells including hepatocellular carcinoma (HepG2), non-small-cell lung cancer (A549) and breast cancer (MCF-7) cells by MTT assay. These complexes showed considerable cytotoxic effect in all the above-mentioned cell lines that was comparable to the effect of cisplatin. C1 and C2 showed moderate anticancer effect while C3 and C4 showed reasonable cytotoxicity. We found the cytotoxicity was increased in series from C1 to C4 representing the effect of ligand modification from small to bulky group at the amine functionality of the salicylaldimine. We selected C3 and C4 for mechanistic anticancer study in MCF-7 cells. The acridine orange/ethidium bromide and DAPI staining assays of MCF-7 cells treated with Ru(II) complexes showed apoptosis in cancer cells. Similarly, these complexes induced p53 protein expression in MCF-7 cells. Further, increased mRNA levels of p63, p73, PUMA, BAX and NOXA genes were observed in response to the treatment with C3 and C4, while cyclinD1, MMP3 and ID1 gene expression was significantly reduced. We found reduced invasion ability in breast cancer cells treated with C3 and C4. Taken together, we demonstrated that bis-salicylaldimine based dimetallic Ru-(p-cymene) complexes exerts anticancer effects by p53 pathway, suggesting the promising chemotherapeutic potentials of these Ru(II) complexes for the treatment of cancer. This study may further pave for their in depth in vitro or in vivo anticancer investigations. PMID- 30282321 TI - Efficient synthesis of new phenanthridine Wnt/beta-catenin signaling pathway agonists. AB - Previously, HLY78, a lycorine derivative, was identified as the first Wnt/beta catenin signaling agonist through binding to the DAX domain of Axin, a scaffold of Wnt/beta-catenin complex. In this study, to obtain more potent Wnt/beta catenin agonist, the structure optimization of HLY78 was carried out by design and synthesis of six phenanthridine derivatives, which afforded five active ones. In particular, 8,9-bis((1,3-dimethyl-1H-pyrazol)methoxy)-5-ethyl-4-methyl-5,6 dihydrophenanthridine showed the most potent activity (0.15/MUM) that was increased nearly 30 times as that of the lead HLY78. These compounds may be valuable in future pharmacological or biological studies. PMID- 30282322 TI - Peptidomimetic growth hormone secretagogue derivatives for positron emission tomography imaging of the ghrelin receptor. AB - The ghrelin receptor is a seven-transmembrane (7-TM) receptor known to have an increased level of expression in human carcinoma and heart failure. Recent work has focused on the synthesis of positron emission tomography (PET) probes designed to target and image this receptor for disease diagnosis and staging. However, these probes have been restricted to small-molecule quinalizonones and peptide derivatives of the endogenous ligand ghrelin. We describe the design, synthesis and biological evaluation of a series of 4-fluorobenzoylated growth hormone secretagogues (GHSs) derived from peptidic (GHRP-1, GHPR-2 and GHRP-6) and peptidomimetic (G-7039, [1-Nal4]G-7039 and ipamorelin) families in order to test locations for the insertion of fluorine-18 for PET imaging. The peptidomimetic G-7039 was found to be the most suitable for 18F-radiolabelling as its non-radioactive 4-fluorobenzoylated analogue ([1-Nal4,Lys5(4-FB)]G-7039), had both a high binding affinity (IC50 = 69 nM) and promising in vitro efficacy (EC50 = 1.1 nM). Prosthetic group radiolabelling of the precursor compound [1-Nal4]G 7039 using N-succinimidyl-4-[18F]fluorobenzoate ([18F]SFB) delivered the PET probe [1-Nal4,Lys5(4-[18F]-FB)]G-7039 in an average decay-corrected radiochemical yield of 48%, a radio-purity >= 99% and an average molar activity of >34 GBq/MUmol. This compound could be investigated as a PET probe for the detection of diseases that are characterised by overexpression of the ghrelin receptor. PMID- 30282323 TI - Broad-spectrum antibacterial amphiphilic aminoglycosides: A new focus on the structure of the lipophilic groups extends the series of active dialkyl neamines. AB - Amphiphilic aminoglycosides (AAGs) constitute a new class of antibacterial compounds targeting the bacterial membranes. We have identified the 3',6-dinonyl neamine 9 as a broad spectrum antibacterial AAG. Here, we report on the synthesis, antibacterial activity and eukaryotic cytotoxicity of new 3',6-dialkyl neamines designed in order to finely delineate the structure-activity relationships relating their activity to a lipophilicity window. New broad spectrum antibacterial derivatives were obtained carrying two identical linear or branched alkyl groups or two different linear alkyl groups. Two fluorescent antibacterial 3',6-heterodialkyl neamines carrying a pyrenylbutyl fluorophore were also identified as potential tools for mechanistic study. Homodialkyl and heterodialkyl neamines appeared to be more active on Gram-negative bacteria than dinaphthylalkyl neamines. However, branched dialkyl neamines or heterodialkyl derivatives were found to be more cytotoxic on mammalian cells than 9. The exposure of P. aeruginosa over one month to half-MIC of one of the most active derivatives 9 demonstrated the high difficulty of resistance emergence to AAGs. PMID- 30282324 TI - Design, synthesis and biological evaluation of novel carbamodithioates as anti proliferative agents against human cancer cells. AB - A series of new carbamodithioates compounds has been successfully synthesized. All the carbamodithioate derivatives of SFE and SFA with benzenethiols (substituted or unsubstituted) exhibited, in general, higher percentages of inhibition than their parent compounds: SFE and SFA. A number of carbamodithioate derivatives with benzenethiols (substituted or unsubstituted) (1l, 1m, 1n, 1o, 1q, 1s, 2l, 2n, 2p, 2q, 2r and 2s) were investigated for in vitro anti proliferative activities against five cancer cell lines: SMMC-7721, A549, A375, HCT 116 and Hela. The carbamodithioate compounds (1l, 1m, 1n, 1o, 1q and 1s) derived from SFE and the carbamodithioate compounds (2l, 2n, 2p, 2q, 2r and 2s) derived from SFA are more sensitive toward SMMC-7721and A549 cancer cells than toward other cancer cells in that their IC50 values are appreciably lower. Moreover, they exhibited stronger inhibitory activities than their parent compound SFE and SFE. Further investigation indicated that these carbamodithioate derivatives inhibited colony formation of SMMC-7721 and remarkably induced the G2/M or G0/G1 phase cell cycle arrest and apoptosis in SMMC-7721 cancer cells. More important, these carbamodithioate derivatives are stable in protic solvent media than their parent compounds. By virtue of the simplicity of the preparation of these carbamodithioate derivatives and their stability, compounds 1m and 2s could be the promising candidates for replacement for their parent SFE and SFA for cancer prevention agents. PMID- 30282325 TI - Fine particles exposure and cardiopulmonary morbidity in Jeddah: A time-series analysis. AB - Health effects linked to PM2.5, have been extensively studied in developed countries of Europe and N. America. However, little has been done in Saudi Arabia and the Middle East. This study evaluated the morbidity risk for cardiovascular (CVD) and respiratory (RD) diseases, associated with PM2.5 exposure in Jeddah, Saudi Arabia. 24-h PM2.5 sampling was conducted at 3 sites for 6 weeks quarterly from Apr 8th, 2013-Feb 18th, 2014 with simultaneous hospital data collection. The relative risks (RRs) for cardiopulmonary morbidity at different moving averages (MAs) of lagged exposures were estimated using a generalized linear time-series model. Elevated risks for RD were associated with recent PM2.5 exposures (0-2 days). RD prevalence was highest in children 0-14 years. Overall, RD morbidity risk ranged from 1.081 (CI: 1.005-1.162) to 1.096 (CI: 1.023-1.173) at MAs_2-4; male, 1.081 (CI: 1.019-1.146) to 1.087 (CI: 1.020-1.159) at MAs_2-3, and female, 1.086 (CI: 1.007-1.172) to 1.093 (CI: 1.017-1.175) at MAs_2-4. Generally, females 0-14 years were the most at risk for RDs with RR = 1.097 (CI: 1.025-1.174) to 1.148 (CI: 1.049-1.257). CVD morbidity risk was highest in ER visits with overall RR = 1.057 (CI: 1.005-1.111) to 1.137 (CI: 1.065-1.213) across all MAs; male, 1.060 (CI: 1.007-1.204) to 1.131 (CI: 1.060-1.208); female, 1.065 (CI: 1.008 1.125) to 1.116 (CI: 1.045-1.192). PM2.5 exposure showed significantly increased cardiopulmonary morbidity risk, accentuating the severe health effects associated with elevated PM2.5 in Jeddah. Overall, females (0-14 years) were more at risk for RD morbidity than males. CVD morbidity risk was relatively higher in males than females, with highest risk observed in age-groups above 40 years. PMID- 30282326 TI - New concepts on carbon redirection in wastewater treatment plants: A review. AB - Wastewater treatment plants (WWTPs) are no longer considered pollution removal systems but rather resources (nutrients and energy) recovery plants. Legislation imposing more stringent effluent requirements and the need energy self-sufficient or even energy-positive plants are the main drivers for the research and development of new WWTP configurations. While a lot of effort has been focused on developing new processes for nutrient recovery, limited efforts have been allocated to maximizing energy recovery from the organic load. Within this context, high-rate activated sludge (HRAS) is the most promising alternative technology to redirect carbon (organic compounds) towards energy as biogas. This is a critical review of the last decade's development of new alternatives for carbon redirection to improve the energy balance of WWTPs on both the laboratory and the industrial scale. PMID- 30282327 TI - Measuring and mapping the effectiveness of the European Air Quality Directive in reducing N and S deposition at the ecosystem level. AB - To protect human health and the environment (namely ecosystems), international air quality protocols and guidelines, like the Gothenburg protocol (1999) and the 2001 EU Air Quality Directive (NECD), conveyed national emission ceilings for atmospheric pollutants (Directive 2001/81/EC), including the reduction of sulfur (S) and nitrogen (N) emissions by 2010. However, to what degree this expected reduction in emissions had reflections at the ecosystem level (i.e. pollutant levels reaching and impacting ecosystems and their organisms) remains unknown. Here, we used lichens as ecological indicators, together with reported air and precipitation pollutant concentrations, to determine and map the consequences of the S and N atmospheric emission's reduction, during the implementation of the 2001 Directive (in 2002 and 2011), due primarily to the industrial-sector. The study area is a mixed-land-use industrialized Mediterranean agroforest ecosystem, in southwest Europe. The reduction of S emissions (2002-2011) was reflected at the ecosystem level, as the same S-declining trend was observed in atmospheric measurement stations and lichens alike (-70%), indicating that most S deposited to the ecosystem had an industrial origin. However, this was not the case for N with a slight N-reduction near industrial facilities, but mostly N-deposition in lichens increased in areas dominated by agricultural land-uses. Taken together, these results highlight the importance of going beyond emissions estimation and modeling, to assess the success of the implementation of the NECD in lowering pollutant accumulation in living organisms and their environment. This can only be achieved by measuring pollutant deposition at the ecosystem level (e.g. living organisms). By doing so, we were able to show that the 2001 NECD was successful in reducing S concentrations from Industry, whereas N remains a challenge. Despite the small reduction in N-emissions, deposition into ecosystems did not reflect these changes as agriculture and transport sectors must reduce NH3 and NOx emissions.

PMID- 30282329 TI - In vivo evaluation of porous lithium-doped hydroxyapatite scaffolds for the treatment of bone defect. AB - Hydroxyapatite (HA) possesses similar mineral components to bone and possesses good physicochemical properties. Even though pure HA scaffold is brittle, it is insufficient in promoting vascularization and osteoinductivity. This study was conducted to assess whether lithium (Li) incorporated into HA could improve the scaffolds' inherent shortcomings. In the experiments, Li-hydroxyapatite scaffolds' mechanical strength, biocompatibility, and biodegradability were researched primarily. In vivo studies, the Li hydroxyapatite scaffolds were implanted into an animal model to repair the bone defects. Meanwhile, we also evaluated the expression of angiogenic and osteogenic factors. For comparison, autologous bone, hydroxyapatite, and blank control groups were designed. According to the results, Li incorporated with hydroxyapatite did not significantly change the scaffold's degradation velocity, but it obtained higher compress mechanical strength. After Li was doped, bone regeneration was further enhanced but the angiogenic effect was not improved significantly. The in vivo study, Li-HA scaffolds improved new bone formation with GSK-3?? decreased and ?? catenin increased. In conclusion, doped Li into hydroxyapatite was an alternative strategy for improving hydroxyapatite's mechanical property and promoting the osteogenesis potential. This method is highly recommended for clinical application based on this study alone. PMID- 30282330 TI - Mechanical loading characteristics of total hip prosthetics subjected to dynamic loading cycles. AB - The selection of best material pair in the hip prosthetics design for improved performance and life relies on the estimation of hip joint contact stresses and contact pressure distribution during various dynamic loading cycles: Climbing Upstairs, Climbing downstairs and Knee bending. The maximum Von Mises stress, contact pressure and deformation are considered factors in selecting the material pair in this current study. This is done by analysis of a three-dimensional finite element model of the acetabular component during the different dynamics cycles using ANSYS(r). The different material combination of bearing couples considered for this analysis are metal in contact with plastic, metal on metal, metal on ceramic, ceramic on plastic, ceramic on metal and ceramic on ceramic. The numerical results were validated by comparing them with the FEA results of Hai-Bo Jiang et al. for the existing material combinations and a high correlation of 92% was observed. We found that the Alumina femoral head paired with ultra high molecular weight polyethylene (UHMWPE) cup reduces the maximum Von Mises stress and maximum contact pressure developed at the interface amongst other material pairs. PMID- 30282331 TI - Optimization of the configuration of porous bone scaffolds made of Polyamide/Hydroxyapatite composites using Selective Laser Sintering for tissue engineering applications. AB - Numerous biomaterials are used to fabricate bone scaffolds to repair the bones subjected to trauma. The scaffolds are fabricated with interconnected pores with 40-70% porosity to facilitate the entry of the cells that ensures rapid bone formation. In addition, the interconnected pores also serve as a channel for the exchange of nutrients and waste materials. Rapid prototyping techniques use the CAD model of the scaffold to be fabricated which facilitates fabrication of components with complex architecture easily. This research deals with the design, fabrication and analysis of porous scaffold models with different configurations. Apart from the conventional pore geometry like cubical, spherical shaped pores, their shifted arrangements were also considered for this study. The minimum pore size used for the study is 400 MUm and the porosity ranges from 40-70%. Based on the results of finite element analysis, the best scaffold configuration is identified and was fabricated with different build orientation using Selective Laser Sintering (SLS) process with different mix of Polyamide and Hydroxyapatite. The fabricated test specimens were evaluated based on mechanical tests for its strength and in vitro studies with human osteosarcoma cell line for cell growth studies. The mechanical tests witnesses good physical properties than the earlier reported research. The suitability of the porous scaffolds for bone repair is also ensured using finite element analysis of a human femur bone under various physical activities. PMID- 30282332 TI - The effects of NELL on corticotomy-assisted tooth movement and osteogenesis in a rat model. AB - INTRODUCTION: Exogenous Nel-like molecule type 1 (NELL1) represents a potentially attractive clinical treatment option in the orthodontic and other settings because of its osteoinductive and vasculogenic properties. AIMS: To explore effects of NELL1on corticotomy-assisted tooth movement and osteogenesis in a rat model. METHODS: Thirty Sprague-Dawley rats were divided into 6 groups: Control, Sham, Tooth movement only, Vehicle, NELL1-LD (low-dose NELL), NELL1-HD (high-dose NELL). Human recombinant NELL1 protein was applied locally (Groups NELL1-LD and NELL1-HD) into buccal mucosa region of left first upper molar. Then the distance and velocity of tooth movement was measured, animals at 6 weeks after surgery were sacrificed, and was followed by computed tomography and histochemical staining. RESULTS: Both NELL1 groups had higher bone mineral density, greater tooth movement distance and velocity in comparison to the Vehicle group. Proximally and distally, periodontal ligament width was significantly increased in the NELL1-LD and NELL1-HD groups. Decortication enhances remodeling, however, rapid bone formation by high-dose NELL1 may affect bone absorption. CONCLUSION: Appropriate dose of NELL1 can be administrated to reduce the total time for tooth movement, and may shorten the treatment time in select populations. PMID- 30282333 TI - Dopant-dependent tailoring of physicochemical and biological properties of calcium silicate bone cements. AB - BACKGROUND: To enhance calcium silicate cements (CSCs) towards a specific clinical application of endodontics and vertebroplasty, the addition of oxide dopants (Bi2O3, SrO, ZnO, ZrO2) as radiopacifiers allows for tailoring of material properties. OBJECTIVE: Effects of oxide dopants on the in vitro physicochemical properties and osetogenic activity of CSCs were investigated. METHODS: The setting time, compressive strength, radiopacity, and osteogenic ability of the cements were evaluated. The ability of cement samples to support MG63 attachment, proliferation, differentiation, and mineralization was assessed. RESULTS: The greater the oxide amount, the higher the setting time and radiopacity were in the cement. The effect of the oxide dopants on radiopacity followed the order Bi2O3 > ZrO2 > SrO > ZnO, which were greater than 3 mm of Al recommended by ISO 6876: 2001 standards. ZrO2 could reinforce compressive strength of the control cement, while ZnO remarkably reduced the strength. The adverse effect of Bi2O3 and ZrO2 was found on cell number, alkaline phosphatase (ALP) activity and mineralization of MG63 cells. SrO supported cell attachment, proliferation and differentiation, and significantly increased cellular mineralization compared to the control. CONCLUSIONS: The 20 wt% SrO-containing CSCs may be applied to endodontic treatment and vertebroplasty surgery. PMID- 30282334 TI - Raman spectroscopic and fractal analysis of blood samples of dengue fever patients. AB - BACKGROUND: The limitations of the existing techniques for the early detection of dengue fever necessitate the development of a powerful optical technique. OBJECTIVE: The present work is a study of Raman spectral modifications of blood on dengue infection and thereby to develop a spectroscopic method for its early detection. The images of the samples are subjected to fractal analysis to find the variation of fractal dimensions on dengue infection. METHODS: Correlation of platelet counts of dengue infected blood with Raman spectrum modification and fractal dimension. The effect of lowering of blood platelet count due to dengue infection is found to show some interesting changes in the spectrum. RESULTS: The full width at half maximum (FWHM) of the two bands in the region 950-1200 cm-1 increase with the decrease of blood platelet count. The increase in fractal dimension gives an indication of the decrease of platelet count and hence the dengue infection. CONCLUSIONS: Raman spectrum and fractal analysis can effectively be used as potential techniques for the early detection of dengue infection. PMID- 30282335 TI - Tissue repair in neonatal and paediatric surgery: Analysis of infection in surgical implantation of synthetic resorbable biomaterials. AB - BACKGROUND: There has been increased interest in the use of biomaterials that resorb completely leaving only the patient's native tissue. Synthetic materials are advantageous for tissue repair because they are highly customisable. The infection rate of using resorbable natural materials in paediatric surgery has recently been outlined, but there has not yet been a review of the use of synthetic resorbable materials in paediatric surgery. OBJECTIVES: This systematic review analyses the risk of infection after implantation of fully resorbable synthetic biomaterials in paediatric cases. METHODS: The literature was searched from January 1970 to January 2018 (inclusive), specifically searching for paediatric cases (0-18 years old), use of synthetic resorbable materials and infection. RESULTS: The infection rate in 3573 cases of synthetic resorbable material implantation was 1.1% (41 cases). A Chi-squared test for independence found infection rate to vary among materials. Of the many biomaterials identified in this review, the highest infection rates were seen in Suprathel's use in burns injuries (12.1%). CONCLUSIONS: This review found a low infection rate in synthetic resorbable materials used in paediatric surgery, with particularly strong evidence for low infection risk in LactoSorb(r) use. PMID- 30282336 TI - Nonthermal control of Escherichia coli growth using extremely low frequency electromagnetic (ELF-EM) waves. AB - BACKGROUND: Escherichia coli (E. coli) bacteria normally live in the intestines of people and animals. Most E. coli are harmless and the treatment of the infection could be achieved by using antibiotics, however the effectiveness is still debatable and needs more investigation. OBJECTIVE: Researching the inhibition resonance frequency of square amplitude modulating waves (QAMW) that can inhibit the growth activity of E. coli and its ability to make division. METHODS: A range of different extremely low frequencies of square amplitude modulated waves (QAMW) from 0.1 to 1.0 Hz from two generators with a constant carrier frequency of 10 MHz, amplitude of 10 Vpp, modulating depth +/- 2 Vpp and constant field strength 200 V/m were used to treat E. coli cells at 37 degrees C. RESULTS: The exposure of E. coli to 0.3 Hz QAMW for 90 min was the most inhibited frequency where the bacterial growth inhibited by 42.3%. Furthermore, a significant increase in antibiotic susceptibility to protein and cell wall inhibitors was investigated. Also, results of the chromosomal DNA sequences, dielectric relaxation and TEM indicated highly significant molecular and morphological changes after the exposure. CONCLUSIONS: We concluded that the exposure of E. coli to QAMW at the inhibiting frequency interfered with the bioelectric signals generated from the bacteria during the cell division and changed the cellular activity and DNA sequences, and these changes lead to a significant inhibition of the bacterial growth. This is a new promising technique that aids to avoid the repetitive use of antibiotics against the bacterial pathogens.

AB - Two common abnormalities in ureters include primary refluxing megaureter (PRM) and primary obstructed megaureter (POM). The aim of this study was to represent the numerical simulation of the urine flow at the end of the ureter with vesicoureteral reflux (VUR) and POM during peristalsis. Methodologically, the peristalsis in the ureter wall was created using Gaussian distribution. Fluid structure interaction (FSI) was applied to simulate urine-elastic wall interactions; and governing equations were solved using the arbitrary Lagrangian Eulerian method. Theories such as wall elasticity, Newtonian fluid, and incompressible Navier-Stokes equations were used. Velocity fields, viscous stresses and volumetric outflow rate profiles were obtained through the simulation of the ureter with VUR and POM during peristalsis. In addition, the effect of urine viscosity on flow rate was investigated. When the bladder pressure increased, VUR occurred because of the ureterovesical junction (UVJ) dysfunction, leading to high stresses on the wall. In the POM, the outflow rate was ultimately zero, and stresses on the wall were severe in the obstructed section. Comparing the results demonstrated that the peristalsis leads to even further dilation of the prestenosis portion. It was also observed that the reflux occurs in the ureter with VUR when the bladder pressure is high. Additionally, the urine velocity during the peristalsis was higher than the non-peristaltic ureter. PMID- 30282338 TI - Repeatability of small bowel transit time in capsule endoscopy in healthy subjects. AB - BACKGROUND: There are no reports to prove the repeatability of gastric transit time (GTT) and small bowel transit time (SBTT) in capsule endoscopy (CE). OBJECTIVE: To clarify the repeatability and factors that affect GTT/SBTT in CE. METHODS: We analyzed the data of 150 healthy subjects from our previous randomized controlled trial that compared small intestinal injuries between two 14-day treatment groups: 1) celecoxib and 2) loxoprofen + lansoprazole. Correlation of GTT/SBTT with pre- and post-treatment CE was analyzed. In addition, the associations of pre-treatment CE SBTT with physical factors, post treatment CE SBTT and the presence of small intestinal mucosal injuries were analyzed. RESULTS: Analyses of 148 subjects pre-treatment CE and 146 subjects post-treatment CE were performed. There were no significant differences between mean GTT and SBTT before and after treatment. Both GTT (?? = 0.22, p < 0.01) and SBTT (?? = 0.47, p < 0.0001) showed positive correlations between pre- and post treatment CE. In pre-treatment CE, physical factors and the presence of small intestinal mucosal injury had no associations with SBTT. CONCLUSIONS: Moderate correlation in SBTT and slight correlation in GTT were shown on repeated CE. The factors affecting SBTT were not clarified in this analysis. PMID- 30282339 TI - Patient-specific design for articular surface conformity to preserve normal knee mechanics in posterior stabilized total knee arthroplasty. AB - BACKGROUND: Contemporary total knee arthroplasty (TKA) provides remarkable clinical benefits. However, the normal function of the knee is not fully restored. Recent improvements in imaging and manufacturing have utilized the development of customized design to fit the unique shape of individual patients. OBJECTIVE: The purpose of the present study is to investigate the preservation of normal knee biomechanics by using specific articular surface conformity in customized posterior stabilized (PS)-TKA. METHODS: This includes customized PS TKA, PS-TKA with conforming conformity (CPS-TKA), medial pivot conformity with PS TKA (MPS-TKA), and PS-TKA with mimetic anatomy femoral and tibial articular surface (APS-TKA). In this study, kinematics, collateral ligament force and quadriceps force were evaluated using a computational simulation under a deep knee bend condition. RESULTS: A conventional TKA did not provide the normal internal tibial rotation with flexion leading to abnormal femoral rollback. The APS-TKA exhibited normal-like femoral rollback kinematics but did not exhibit normal internal tibial rotation. However, APS-TKA exhibited the most normal-like collateral ligament and quadriceps forces. CONCLUSIONS: Although the APS-TKA exhibited more normal-like biomechanics, it did not restore normal knee biomechanics owing to the absence of the cruciate ligament and post-cam mechanism. PMID- 30282340 TI - Mechanical properties of cancellous tissue in compression test and nanoindentation. AB - The goal of the study was to determine material constants of cancellous tissue in a compression test taking into account stress-strain characteristics. The nineteen test samples were resected from a femoral head of a patient qualified for a hip replacement surgery. During the compression tests, load-displacement curves were evaluated and stress-strain characteristics (??-??) of the cancellous bone tissue were calculated. A special one-touch extensometer was used. The use of an extensometer improves the displacement measurement accuracy with respect to the measurement using standard crosshead. The obtained values of the mechanical parameters as well as the stress-strain curves are the basis for further research going into the development of bone tissue constitutive equations. PMID- 30282341 TI - Magnesium doping on TiN coatings affects mesenchymal stem cell differentiation and proliferation positively in a dose-dependent manner. AB - BACKGROUND: In vitro evaluation of cell-surface interactions for hard tissue implants have mostly been done using osteoblasts. However, when an implant is placed in the body, mesenchymal stem cells (MSCs) play a major role in new bone formation. Therefore, using MSCs in cell-surface investigations may provide more reliable information on the prediction of in vivo behavior of implants. OBJECTIVE: In this study, Mg doped TiN coatings ((Ti,Mg)N) were prepared and tested for their effect on MSC differentiation and mineralization. METHODS: MSCs were isolated from rat bone marrow (rBMSCs) and seeded onto bare Ti, TiN and Mg containing (Ti,Mg)N surfaces. Cell proliferation, osteogenic differentiation (collagen type 1, alkaline phosphatase activity), calcium phosphate deposition (von Kossa staining, Scanning Electron Microscopy) analysis were conducted. RESULTS: Differentiation towards osteoblast lineage was significantly improved with the increment in Mg presence. Collagen type I deposition, mineralization, and the ALP activity were higher on high Mg containing (>10 at% Mg) surfaces but differentiation of rBMSCs were found to be delayed. CONCLUSIONS: Mg presence affected rBMSCs proliferation and differentiation positively in a dose-dependent manner. However, high Mg amounts delayed both proliferation and differentiation. PMID- 30282343 TI - Review of core-multishell nanostructured models for nano-biomedical and nano biopharmaceutical application. AB - The main advantage of a theoretical approach is essential knowledge of the mechanisms that allow us to comprehend the experimental conditions that we have to fulfill to be able to get the desired results. Based on our research in ultrathin crystal structures performed so far, superlattices, Q-wires and Q-dots, we will consider the materials that can act as carriers for medicines and tagged substances. For this purpose we established a shell-model of ultrathin crystals and investigated their fundamental characteristics. This could be considered as a form of nano-engineering. In this paper we will analyze application of nanomaterials in biomedicine, that is to say we will present the recent accomplishments in basic and clinical nanomedicine. Achieving full potential of nanomedicine may be years or even decades away, however, potential advances in drug delivery, diagnosis, and development of nanotechnology-related drugs start to change the landscape of medicine. Site-specific targeted drug delivery (made possible by the availability of unique delivery platforms, such as dendrimers, nanoparticles and nanoliposomes) and personalized medicines (result of the advance in pharmacogenetics) are just a few concepts on the horizon of research. In this paper, especially, we have analyzed the changes in basic physical properties of spherical-shaped nanoparticles that can be made in several (nano)layers and have, at the same time, multiple applications in medicine. This paper presents a review of our current achievement in the field of theoretical physics of ultrathin films and possible ways to materialize the same in the field of nanopharmacy. PMID- 30282342 TI - Evaluation of swelling processes of various natural polymer matrix tablets by X ray computed tomography and controlled drug release. AB - BACKGROUND: The swelling properties and the drug-release sustainability of pre gelatinized starches (??-starch) tablets depend on the polymer characteristics. OBJECTBS: In order to clarify the drug release form, the natural polymers (NPs) were investigated. The relationship between drug release and swelling of natural polymers (NPs), the swelling processes of various starch polymers, were investigated using a drug-release test (DRT) and X-ray computed tomography (XCT). NPs consisting of various starches such as glutinous rice starch (GRS), corn starch (CS), and tapioca starch (TS) were used as additives for sustained drug release tablets. Tablets consisted of 5% theophylline, 94% ??-starch, and 1% magnesium stearate and were compressed at 6 kN. DRTs were measured in distilled water at 37 degrees C, and the drug concentrations were measured using UV (271 nm). Swelling ratio (R) profiles of the tablets during DRTs were evaluated based on XCT images. RESULTS: The order of the drug-release rate constant of the tablets was TS < GRS < CS. XCT images of the tablets were measured during the DRTs, and CS, GRS, and TS tablets swelled and showed increased gel-layers, and then finally disintegrated at 6, 9, and 11 h, respectively. CONCLUSION: The relationship between R profile and the % drug release of the tablets differed depending on the kind of NP used. PMID- 30282344 TI - A finite element analysis for monitoring the healing progression of fixator-bone system under three loading conditions. AB - BACKGROUND: Unilateral external fixators are widely used in orthopedics to stabilize fractured bones and in the treatment of limb deformities. The main value for evaluation of mechanical stability of the external fixator is fixator stiffness. The fixator stiffness is an important factor as it will influence the biomechanical environment to which fixator and regenerating tissues are exposed. OBJECTIVE: The main objective of this work was to monitor the transmission of stress and the change of displacement generated in fixator-bone system under three loading conditions during healing process. METHODS: In this study, a finite element model with changing Young's modulus of the callus is established, finite element analysis was used to investigating stress and deformation of fixator-bone system caused by axial load, torsional load and bending load during three healing stages. RESULTS: The results reveal that at different healing stages, stress distribution between the fixator and fractured bone is different, the position of displacement is mainly concentrated in the fracture site and proximal bone and with the increase of healing time, the deformation decreased. CONCLUSIONS: This work helps orthopedic doctors to monitor the progression of fracture healing and determine the appropriate time for removal of a fixation device and provide useful information. PMID- 30282345 TI - Biomechanical evaluation of four surgical scenarios of lumbar fusion with hyperlordotic interbody cage: A finite element study. AB - BACKGROUND: Lumbar spinal fusion in the interbody space is augmented with interbody fusion cages to provide structural support while arthrodesis occurs. Subsidence is a serious complication of interbody fusion. However, the biomechanical influence of anterior longitudinal ligament (ALL) and pedicle screws on subsidence has not been fully understood. OBJECTIVE: To investigate biomechanical effects of the hyperlordotic cages in different surgical conditions using finite element analysis. METHODS: Four surgical finite element (FE) models were constructed by inserting 15 degree lordosis cage at the L3-L4 disc space. The four surgical conditions were ALL intact (M1), ALL resected (M2), ALL intact and bilateral pedicle screws (M3), and ALL resected and bilateral pedicle screws (M4). Follow loads were applied at the L2 vertebral body while the inferior surface of L5 was fixed. FEA was implemented to simulate the four motion modes and biomechanical properties of four fusion scenarios with hyperlordotic interbody cage were compared. RESULTS: The range of motion (ROM) and facet joint force (FJF) at L3-L4 decreased significantly after fusion during all the motion modes. The cage stress and endplate stress at L3-L4 increased significantly after fusion during all the motion modes. The cage stress and endplate stress at L3-L4 for M3 and M4 were smaller than that for M1 and M2 during all the motion modes. The FJF at L3-L4 for M3 and M4 were smaller than that for M1 and M2 during extension, bending, and rotation. CONCLUSIONS: ALL has little effect on the biomechanics after lumbar fusion with hyperlordotic interbody cage. The bilateral pedicle screws significantly decreased the stress in cage, stress in endplate at L3-L4, and lowered facet contact force except for flexion mode. The implication is that the supplemental bilateral pedicle screws are recommended whether or not the ALL is resected. PMID- 30282346 TI - Dynamic response and material sensitivity analysis of pelvic complex numerical model under side impact. AB - BACKGROUND: The surrogate design and clinical diagnostic suggest that the pelvic dynamic response should be the basis of bone fracture mechanism study under side impact. Pelvic response indicators are the impact force, compression (C), viscous criterion (VC), bone stress, and bone strain. However, no evaluation of these indicators has been conducted. OBJECTIVE: To evaluate pelvic response indicators under side impact. METHODS: A sitting pelvic finite element (FE) complex model comprising bone, artery, ligaments, and soft tissue was constructed. The dynamic response of the model under side impact with initial velocity of 3 m/s was investigated and material sensitivity analysis was complemented by changing bone elastic modulus. RESULTS: The pelvic FE model could predict response under side impact. Specifically, the indicators such as artery pressure and strain, together with the ligaments axial force and strain were provided. The sensitivity analysis showed the impact force, bone stress, and axial force were sensitive to the elastic modulus, whereas, C, VC, bone strain, and artery pressure were not. CONCLUSIONS: The sitting FE model in this study can predict pelvic dynamic response, and C, VC, bone strain and artery pressure are proposed for pelvic tolerance instead of impact force under side impact. PMID- 30282347 TI - Influence of different implant-abutment connections on stress distribution in single tilted implants and peripheral bone: A three-dimensional finite element analysis. AB - BACKGROUND: The load transfer between the implant-bone interface depends on various factors, including loading type; material properties of the implant and prosthesis; and implant geometry, length, diameter, and shape. OBJECTIVE: The purpose of this study was to evaluate stress distribution in single tilted bone level implants with different connections and peripheral bone under vertical and oblique loads using three-dimensional (3D) finite element analysis (FEA).METHOS.3D models of four different implant systems and their abutments were created from the data (computer-aided design) of original implants and abutments scanned with an optical scanner. The implants were placed in the bone block at degrees of 0 degrees , 15 degrees , and 30 degrees . Then, a 3D model of the metal-ceramic crown was created and a 100-N total load was applied vertically and obliquely. RESULTS: Stress analyses showed variable results depending on the connection design and tilting angle; however, the tube in tube (TIT) connection type exhibited lower stress values in most loading and tilting simulations. CONCLUSIONS: Increase in tilting angle showed variable results in each connection design. The TIT connection design was found to be more successful in terms of stress distributions in the implant components and the peripheral bone. PMID- 30282348 TI - Regional pulse wave velocity and stress in aneurysmal arch-shaped aorta. AB - The pulse wave velocity (PWV) has been shown to be associated with the properties of blood vessel and a cardiovascular risk factor such as aneurysm. The global PWV estimation is applied in conventional clinical diagnosis. However, the geometry of blood vessel changes along the wave traveling path and the global PWV estimation may not always detect regional wall changes resulting from cardiovascular diseases. In this study, a fluid structure interaction (FSI) analysis was applied on arch-shaped aortas with and without aneurysm aimed at determining the effects of the number of aneurysm, aneurysm size and the modulus ratio (aneurysm to wall modulus) on the pulse wave propagation and velocity. The characterization for each stage of aneurysmal aorta was simulated by progressively increasing aortic stiffness and aneurysm size. The pulse wave propagations and velocities were estimated from the two-dimensional spatial temporal plot of the normalized wall displacement based on elastic deformation. The descending forward and arch reflected PWVs of aneurysmal aortic arch models were found up to 9.7% and 122.8%, respectively, deviate from the PWV of non aneurysmal aortic arch model. The PWV patterns and magnitudes can be used to distinguish the characterization of the normal and aneurysmal aortic walls and shown to be relevant regional markers utilized in clinical diagnosis. PMID- 30282349 TI - Effect of core stability exercises on postpartum lumbopelvic pain: A randomized controlled trial. AB - BACKGROUND: Core stability exercises have been widely advocated for management of patients with different musculoskeletal conditions, even though its effect on postpartum lumbopelvic pain (LPP) has not been fully investigated. OBJECTIVE: This study was conducted to investigate the effect of core stability exercises on postpartum LPP. METHODS: Thirty four women suffering from postpartum LPP were randomly assigned to the study or control group. The control group (n= 17) received infrared radiation and continuous ultrasound on lumbosacral region (L1 S5), whereas the study group (n= 17) received core stability exercises in addition to infrared radiation and continuous ultrasound three sessions a week for six weeks. Pain Pressure Threshold (PPT), Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) were assessed for all participants in both groups before and after the treatment program. RESULTS: There was a significant improvement in PPT, VAS and ODI post-treatment compared with the pre-treatment in both groups (p= 0.001). There was a significant improvement in participants who received core stability exercises as compared to participants treated with the traditional treatment in PPT (P= 0.001), VAS (P= 0.001) and ODI (P= 0.009). CONCLUSIONS: Core stability exercises in addition to conventional treatment significantly decreased pain and improved function for women with postpartum LPP. PMID- 30282350 TI - Production and characterization of monoclonal antibodies against recombinant extracellular domain of CD99. AB - BACKGROUND AND OBJECTIVE: CD99/MIC2gene product is a heavily glycosylated transmembrane protein which plays a major role in homotypic cell adhesion, apoptosis of double positive T cells and vesicular protein trafficking. It is over expressed in various cancers and has been considered as an ideal therapeutic target. The present study focused at developing monoclonal antibodies against the extracellular domain (ECD) of CD99 using hybridoma technology. MATERIALS AND METHODS: In order to generate monoclonal antibodies, the recombinant ECD of CD99 was used for immunizing the mice. Resulting hybridomas were screened through indirect ELISA. Clones which gave high absorbance values were sub cloned by limiting dilution followed by isotype determination, IP, WB and FACS. The monoclonal antibody 547F2 4F12 was purified from culture supernatant using FPLC and further screened using IF. Finally, the antibodies were validated for specificity using siRNA knock-down. RESULTS: We were able to establish stable hybridoma clones secreting CD99 antibodies. The antibodies reacted with both the recombinant ECD as well as the wild type CD99 and their isotype's were determined as IgM. CONCLUSION: Based on these results, we propose that the purified monoclonal antibody 547F2 4F12 could be possibly used for targeting tumors which over express CD99. PMID- 30282351 TI - Visual Processing of Emotional Faces is Preserved in Mild Cognitive Impairment. AB - BACKGROUND: Research suggests that deficits in emotion recognition are evident in individuals with amnestic mild cognitive impairment (aMCI), a group 'at risk' of developing dementia. The mechanisms underlying this deficit, however, are unclear. OBJECTIVE: In this study, we sought to determine whether there are alterations in the way in which individuals with MCI visually explore emotional facial stimuli. METHODS: Eighteen healthy older controls (mean age = 64.6 years) and 32 individuals with MCI were recruited including 18 with the non-amnestic multiple domain (naMCI-md) subtype (mean age = 63.8 years) and 14 with the amnestic multiple domain (aMCI-md) subtype (mean age = 67.9 years). All participants were given a novel eye-tracking paradigm to investigate eye gaze while viewing images of emotional faces on a computer screen. RESULTS: Analyses of eye gaze revealed no significant difference in the percentage of time that groups spent fixating on facial and peripheral facial regions when viewing emotional faces. All participants showed a relative preference for the eye region of faces relative to all other regions. Individuals with aMCI-md were found to be less accurate than controls and naMCI-md on emotion recognition measures. For naMCI-md individuals, significant relationships were found between efficiencies in visual scanning and increased fixation time on the eye region. CONCLUSIONS: Visual processing strategies adopted by aMCI-md individuals when exploring emotional faces do not significantly differ from those of healthy controls or naMCI-md individuals. This suggests that impaired facial emotion recognition in aMCI-md is not likely accounted for by visual processing differences, but rather may reflect an eroded ability to extract meaningful cues from the eye region. PMID- 30282352 TI - Parietal Involvement in the Semantic Variant of Primary Progressive Aphasia with Alzheimer's Disease Cerebrospinal Fluid Profile. AB - Semantic variant of primary progressive aphasia (svPPA) is typically associated with non-Alzheimer's disease (AD) pathology. However, some anatomopathological studies have found AD lesions in those patients. We compared brain perfusion SPECT of 18 svPPA patients with cerebrospinal fluid (CSF) biomarkers indicative of non-AD pathology (svPPA-nonAD) and three svPPA patients with CSF biomarkers indicative of underlying AD (svPPA-AD). All svPPA patients had severe left temporopolar hypoperfusion. SvPPA-nonAD had additional anterior cingulate and mediofrontal hypoperfusion, whereas svPPA-AD had greater left parietal and posterior cingulate involvement. Parietal damage in svPPA constitutes a biomarker for underlying Alzheimer pathology thus refining the classification of this PPA variant. PMID- 30282353 TI - Microglia CREB-Phosphorylation Mediates Amyloid-beta-Induced Neuronal Toxicity. AB - Extracellular accumulation of amyloid-beta (Abeta) forming senile plaques is one of the hallmark pathologies in Alzheimer's disease (AD), while the mechanisms underlying the neuronal toxic effect of Abeta are not fully understood. Here, we found that intracerebroventricular infusion of the aged Abeta42 in mice only induces memory deficit at 24 h but not at 7 days. Interestingly, a remarkably increased CREB (cAMP response element-binding protein) Ser133-phosphorylation (pS133-CREB) with microglial activation was detected at 24 h but not at 7 days after Abeta infusion. Abeta treatment for 24 h increased pS133-CREB level in microglia of the hippocampal non-granular cell layers with remarkably decreased pS133-CREB immunoreactivity in neurons of the hippocampal granular cell layers, including CA1, CA3, and DG subsets. Inhibition of microglia activation by minocycline or CREB phosphorylation by H89, an inhibitor of protein kinase A (PKA), abolished Abeta-induced microglia CREB hyperphosphorylation with restoration of neuronal function and attenuation of inflammatory response, i.e., reduced levels of interleukin-6 (IL6) and pCREB binding of matrix metalloproteinase-9 (MMP9) DNA. Finally, treatment of the primary hippocampal neurons with Abeta-potentiated microglia media decreased neuronal GluN1 and GluA2 levels, while simultaneous inhibition of PKA restored the levels. These novel findings reveal that intracerebroventricular infusion of Abeta only induces transient memory deficit in mice and the molecular mechanisms involve a stimulated microglial CREB phosphorylation. PMID- 30282354 TI - Possible Role of Chitin-Like Proteins in the Etiology of Alzheimer's Disease. AB - Chitin is a beta-linked straight chain carbohydrate matrix monopolymer prominent in invertebrates, from fungi to arthropods. Surprisingly, chitin is now documented in vertebrates, including humans, a component of vertebrate physiology that has been neglected until now. Chitin levels are elevated in Alzheimer's disease (AD) patients, not only in the central nervous system but also in the cerebrospinal fluid and plasma. Elevated levels of chitin lectin have been reported in patients with AD. Chitinase activity varies widely in the human population. Chitin levels can increase in individuals with intrinsically low chitinase activity. Elevated amounts of chitin can reflect accumulation of the small chitin fragments that remain wherever rapid hyaluronan synthesis occurs. Another source of chitin may be from remote fungal infections. Chitin can be toxic for neurons, and its accumulation may lead to the development of AD. We present new suggestions for animal models and treatment modalities that could prove useful in future research endeavors. An unexpected connection with Gaucher's disease patients and their heterozygote relatives is also identified. These chitin-related mechanisms are novel approaches to AD whose etiology until now has defied explication. PMID- 30282355 TI - Effect of Physical Activity on the Progression of Alzheimer's Disease: The Clinical Research Center for Dementia of South Korea Study. AB - BACKGROUND: There is a lack of research on the effects of physical activity (PA) on the progression of Alzheimer's disease (AD). OBJECTIVES: We investigated whether PA is associated with progression of dementia and mortality in AD. METHODS: In the present study, 934 patients with mild-to-moderate AD were included. PA was evaluated using a questionnaire written by the caregiver. The outcome measures were the Clinical Dementia Rating-Sum of Boxes (CDR-SB), Seoul Instrumental Activities of Daily Living (S-IADL), Caregiver-Administered Neuropsychiatric Inventory (CGA-NPI), a global composite score of neuropsychological subtests, and mortality. They were evaluated annually and received a maximum of three follow-up examinations. RESULTS: Between-group differences compared with the no PA group in the change of CDR-SB scores were 0.431 (95% CI = -0.824~-0.039; p = 0.031) for the moderate PA group (150-750 minutes per week of moderate intensity PA), and -1.148 (-1.656~-0.639; p < 0.001) for the high PA group (>750 minutes per week). As PA increased, there was a significant trend to slow the rate of increase in the CDR-SB, S-IADL, and CGA-NPI scores. The patients with >=150 minutes per week for each of non-recreational and recreational PAs had a lower risk of mortality compared to those with <150 minutes per week for each of the PAs (hazard ratio 0.22, 95% CI = 0.05~0.88; p = 0.033). CONCLUSION: More PA is associated with slower progression of dementia severity, functional decline, and abnormal behavior, and with a lower risk of mortality in AD. PMID- 30282356 TI - Subjective Cognitive Decline Prediction of Mortality: Results from the Einstein Aging Study. AB - BACKGROUND: The relation of pre-dementia stages to mortality has not been fully explored. Previous work examining subjective cognitive decline (SCD) and mortality is limited and mixed regarding methods used and consistency of findings. OBJECTIVE: To examine SCD and mortality in a longitudinal, community based cohort, using item response theory (IRT) methodology to form a composite SCD measure. Also, to assess whether this relationship was independent of clinical cognitive status. METHODS: The Einstein Aging Study is a diverse longitudinal cohort of adults aged >=70. SCD items were extracted from baseline CERAD questionnaires and a composite score was formed using IRT methodology. A total of 1,741 participants with complete data were clinically diagnosed as cognitively normal, or as having amnestic mild cognitive impairment (aMCI), nonamnestic mild cognitive impairment (naMCI), or dementia. 645 deaths occurred over a period of 8,912 person-years of follow-up. Cox proportional hazard models predicted time to death adjusting for covariates. RESULTS: A one standard deviation unit increase in level of SCD was associated with >20% higher risk of mortality. However, when models were adjusted for clinical cognitive status, the association was no longer significant. Both dementia and aMCI predicted mortality. Furthermore, when analyses focused only on those without cognitive impairment, SCD level did not predict mortality. CONCLUSIONS: The association of SCD with mortality may be due to the association of SCD with clinical cognitive status. Thus, SCD may be used as a community-based screen to initially identify those with cognitive impairment who may be at greatest risk for death. PMID- 30282357 TI - Learning Processes and Brain Connectivity in A Cognitive-Motor Task in Neurodegeneration: Evidence from EEG Network Analysis. AB - Electroencephalographic (EEG) rhythms are linked to any kind of learning and cognitive performance including motor tasks. The brain is a complex network consisting of spatially distributed networks dedicated to different functions including cognitive domains where dynamic interactions of several brain areas play a pivotal role. Brain connectome could be a useful approach not only to mechanisms underlying brain cognitive functions, but also to those supporting different mental states. This goal was approached via a learning task providing the possibility to predict performance and learning along physiological and pathological brain aging. Eighty-six subjects (22 healthy, 47 amnesic mild cognitive impairment, 17 Alzheimer's disease) were recruited reflecting the whole spectrum of normal and abnormal brain connectivity scenarios. EEG recordings were performed at rest, with closed eyes, both before and after the task (Sensory Motor Learning task consisting of a visual rotation paradigm). Brain network properties were described by Small World index (SW), representing a combination of segregation and integration properties. Correlation analyses showed that alpha 2 SW in pre-task significantly predict learning (r = -0.2592, p < 0.0342): lower alpha 2 SW (higher possibility to increase during task and better the learning of this task), higher the learning as measured by the number of reached targets. These results suggest that, by means of an innovative analysis applied to a low-cost and widely available techniques (SW applied to EEG), the functional connectome approach as well as conventional biomarkers would be effective methods for monitoring learning progress during training both in normal and abnormal conditions. PMID- 30282358 TI - Amyloid and FDG PET of Successful Cognitive Aging: Global and Cingulate-Specific Differences. AB - BACKGROUND: Some individuals, called Supernormals (SN), maintain excellent memory in old age. While brain structural and functional integrity in SN seem to be aging-resistant, their amyloidosis and neural injury status has not been well studied. OBJECTIVE: The goal of this study was to compare cortical amyloid deposition and glucose metabolism between SN and older adults with normal cognition (NC), amnestic mild cognitive impairment (MCI), and Alzheimer's disease (AD). METHODS: Subjects from the ADNI database were included if they received T1 weighted MRI, amyloid PET, FDG-PET, and cognitive testing within a 6-month period, yielding 27 AD, 69 MCI, 172 NC, and 122 SN. PET standardized uptake value ratios (SUVrs) were calculated for the whole cortex and 68 regions of interest, with whole cerebellum serving as reference. RESULTS: SN had lower whole cortex amyloid than MCI, and higher glucose metabolism than all others. Regional analysis revealed that amyloid burden and glucose metabolism in the right isthmus cingulate cortex differed in SN compared to others, while SN glucose metabolism also differed from others in several frontal and temporal regions. CONCLUSION: Preserved cortical glucose metabolism, and lower levels of amyloidosis and glucose hypometabolism in the right isthmus cingulate cortex, contributes to the Supernormal phenomenon. These findings may be informative for development of early screening biomarkers and therapeutic targets for modification of cognitive trajectories. PMID- 30282359 TI - Brain Amyloid Contribution to Cognitive Dysfunction in Early-Stage Parkinson's Disease: The PPMI Dataset. AB - BACKGROUND: The pathological processes underlying cognitive impairment in Parkinson's disease (PD) are heterogeneous and the contribution of cerebral amyloid deposits is poorly defined, particularly in the early stages of the disease. OBJECTIVE: To investigate regional [18F]florbetaben binding to amyloid beta (Abeta) and its contribution to cognitive dysfunction in early stage PD. METHODS: A multicenter cohort of 48 PD patients from the Parkinson's Progression Marker Initiative (PPMI) underwent [18F]florbetaben positron emission tomography (PET) scanning. Clinical features, including demographic characteristics, motor severity, cerebrospinal fluid (CSF), and cognitive testing were systematically assessed according to the PPMI study protocol. For the purpose of this study, we analyzed various neuropsychological tests assessing all cognitive functions. RESULTS: There were 10/48 (21%) amyloid positive PD patients (PDAbeta+). Increased [18F]florbetaben uptake in widespread cortical and subcortical regions was associated with poorer performance on global cognition, as assessed by Montreal Cognitive Assessment (MoCA), and impaired performance on Symbol Digit Modality test (SDMT). Further, we found that PDAbeta+ patients had higher CSF total-tau/Abeta1 - 42 (p = 0.001) and phosphorylated-tau/Abeta1 - 42 in (p = 0.002) compared to amyloid-negative PD. CONCLUSION: These findings suggest that multiple disease processes are associated with PD cognitive impairment and amyloid deposits may be observed already in early stages. However, prevalence of amyloid positivity is in the range of literature age-matched control population. Increased cortical and subcortical amyloid is associated with poor performance in attentive-executive domains while cognitive deficits at MoCA and SDMT may identify amyloid-related dysfunction in early PD. PMID- 30282360 TI - Neuroprotective Effects of Amylin Analogues on Alzheimer's Disease Pathogenesis and Cognition. AB - Type II diabetes (T2D) has been identified as a major risk factor for the development of Alzheimer's disease (AD). Interestingly, both AD and T2D have similar characteristics including amyloid peptide aggregation, decreased metabolism, and increased oxidative stress and inflammation. Despite their prevalence, therapies for these diseases are limited. To date, most therapies for AD have targeted amyloid-beta or tau. Unfortunately, most of these clinical trials have been largely unsuccessful, creating a crucial need for novel therapies. A number of studies have shown that metabolic hormone therapies are effective at ameliorating high blood glucose levels in diabetics as well as improving cognitive function in AD and mild cognitive impairment patients. Pramlintide, a synthetic analogue of the pancreatic hormone amylin, has been developed and used for years now as a treatment for both type I diabetes and T2D due to the loss of beta-islet cells responsible for producing amylin. Importantly, recent data demonstrates its potential therapeutic role for AD as well. This review aims at addressing parallels between T2D and AD at a pathological and functional level, focusing on amylin signaling as a key, overlapping mediator in both diseases. The potential therapeutic use of this hormone to treat AD will also be explored from a mechanistic viewpoint. PMID- 30282361 TI - Aortic Stiffness is Associated with Increased Risk of Incident Dementia in Older Adults. AB - Cardiovascular disease risk factors, including age, hypertension, and diabetes, contribute to aortic stiffness and subclinical cardiovascular and brain disease, increasing dementia risk. Aortic stiffness, measured by carotid-femoral pulse wave velocity (cfPWV), reduces the buffering of pulsatile blood flow, exposing cerebral small arteries to microvascular damage. High cfPWV is related to white matter hyperintensities and brain amyloid deposition, and to cognitive decline, but it is unclear whether cfPWV independently predicts incident dementia. Therefore, we tested the hypothesis that cfPWV predicts incident dementia in older adults, independent of potential confounders. The Cardiovascular Health Study Cognition Study followed 532 non-demented older adults with annual cognitive exams from 1998-99 through 2013. CfPWV was measured on 356 (mean age = 78, 59% women) between 1996-2000. Over 15 years, 212 (59.6%) developed dementia (median time from cfPWV measurement = 4 years). In age and sex-adjusted Cox models, cfPWV was significantly associated with increased risk of dementia, but systolic blood pressure, mean arterial pressure and pulse pressure were not. CfPWV (transformed as - 1/cfPWV) remained significantly associated with dementia risk when further adjusted for education, race, APOEE4, diabetes, body mass index, mean arterial pressure, and anti-hypertensive medication (hazard ratio = 1.60, 95% CI = 1.02, 2.51). Results were similar when further adjusted for baseline global cognition, subclinical brain measures, and coronary artery calcification. Finally, higher cfPWV was related to lower physical activity intensity and higher systolic blood pressure, heart rate, and waist circumference measured 5 years prior. An important unanswered question is whether interventions to slow arterial stiffening can reduce the risk of dementia. PMID- 30282363 TI - Frontotemporal Dementia Misdiagnosed for Post-Treatment Lyme Disease Syndrome or vice versa? A Treviso Dementia (TREDEM) Registry Case Report. AB - We describe the case of a 61-year-old woman diagnosed with Borreliosis at the age of 57. Subsequently, the patient developed depression, anxiety, and behavioral disturbances. A lumbar puncture excluded the condition of Neuroborreliosis. The diagnostic workup included: an MRI scan, a 18F-FDG PET, a 123I-ioflupane-SPECT, an amyloid-beta PET, a specific genetic analysis, and a neuropsychological evaluation. Based on our investigation, the patient was diagnosed with probable behavioral-frontotemporal dementia (bvFTD), whereas in the previous years, the patient had been considered firstly as a case of Post-Treatment-Lyme Disease and, secondly, a psychiatric patient. We believe that, in the present case, such initial symptoms of Borrelia infection may have superimposed on those of bvFTD rather than playing as a contributory cause. PMID- 30282362 TI - Neurotoxic Effects of Abeta6-42 Peptides Mimicking Putative Products Formed by the Angiotensin Converting Enzyme. AB - Angiotensin converting enzyme (ACE) is involved in proteolytic processing of the amyloid-beta(Abeta) peptide implicated in the development of Alzheimer's disease (AD) and known products of ACE-based processing of Abeta42 are characterized by reduced aggregability and cytotoxicity. Recently it has been demonstrated that ACE can act as an arginine specific endopeptidase cleaving the N-terminal pentapeptide (Abeta1-5) from synthetic Abeta peptide analogues. In the context of proteolytic processing of full length Abeta42, this suggests possible formation of Abeta6-42 species. The aim of this study was to test a hypothesis that some N terminally truncated Abeta peptide(s) could retain aggregability and neurotoxic properties typical for Abeta42. We have investigated aggregability of two amyloid beta peptides, Abeta6-42 and isoD7-Abeta6-42, mimicking potential proteolytic products of Abeta42 and isoD7-Abeta42, and evaluated their effects on the repertoire of brain Abeta binding proteins, and cytotoxicity towards neuroblastoma SH-SY5Y cells. Aggregability of isoD7-Abeta6-42 and Abeta6-42 was higher than that of full-length peptides Abeta42 and isoD7-Abeta42, while the repertoire of mouse brain Abeta binding proteins dramatically decreased. Abeta6 42 and isoD7-Abeta6-42 exhibited higher neurotoxicity towards SH-SY5Y cells than Abeta42 and isoD7-Abeta42, respectively. They effectively stimulated production of ROS and NO, and also TNFalpha secretion by cells. Thus, our results suggest that ACE-dependent processing of full-length Abetas could result in formation of more pathogenic peptides. PMID- 30282364 TI - Positive Feedback Loops in Alzheimer's Disease: The Alzheimer's Feedback Hypothesis. AB - The dominant model for Alzheimer's disease (AD) is the amyloid cascade hypothesis, in which the accumulation of excess amyloid-beta (Abeta) leads to inflammation, excess glutamate and intracellular calcium, oxidative stress, tau hyperphosphorylation and tangle formation, neuronal loss, and ultimately dementia. In a cascade, AD proceeds in a unidirectional fashion, with events only affecting downstream processes. Compelling evidence now exists for the presence of positive feedback loops in AD, however, involving oxidative stress, inflammation, glutamate, calcium, and tau. The pathological state of AD is thus a system of positive feedback loops, leading to amplification of the initial perturbation, rather than a linear cascade. Drugs may therefore be effective by targeting numerous points within the loops, rather than concentrating on upstream processes. Anti-inflammatories and anti-oxidants may be especially valuable, since these processes are involved in many loops and hence would affect numerous processes in AD. PMID- 30282365 TI - The Novel DA-CH3 Dual Incretin Restores Endoplasmic Reticulum Stress and Autophagy Impairments to Attenuate Alzheimer-Like Pathology and Cognitive Decrements in the APPSWE/PS1DeltaE9 Mouse Model. AB - Alzheimer's disease (AD) afflicts more than 46.8 million people worldwide, with a newly diagnosed case every 3 seconds and no remission in the disease progression. The discovery of disease-modifying drugs is now on the summit of the neuropharmacological research priorities. The long-lasting derivatives of the insulinotropic incretin hormones-glucagon-like peptide 1 (GLP-1) and glucose dependent insulinotropic polypeptide (GIP)-have repeatedly been shown to cross the blood-brain barrier and counteract an array of deleterious effects across a range of experimental models of neuronal degeneration. Clinical trials for the efficacy of GLP-1 agonists in Alzheimer's and Parkinson's diseases have revealed beneficial effects of these anti-diabetic agents in halting neuronal degeneration progression. Herein, we examine whether the chronic treatment with the novel dual GLP-1/GIP receptor agonist DA-CH3 can restore the cognitive decline and AD-like cerebral pathology of the APPSWE/PS1DeltaE9 mouse model at the age of 10 months old. We report that once-a-daily, eight-week intraperitoneal administration of 25 nmol/kg of the novel DA-CH3 dual-incretin analog rescues the spatial acquisition and memory impairments of this murine model that corresponds to the attenuation of the excessive plaque deposition, gliosis and synaptic damage in the APPSWE/PS1DeltaE9 brain. The amelioration of the AD-related pathology reflects the resolution of the endoplasmic-reticulum stress and derailed autophagy that both lay downstream of the rectified Akt signaling. Collectively, our findings endorse the beneficial effects of the incretin-based therapeutic approaches for the neurotrophic support of the AD brain and for the first time associate the incretin-induced neuroprotection with the proteostasis machinery in vivo. PMID- 30282367 TI - Class-Specific Incidence of All-Cause Dementia and Alzheimer's Disease: A Latent Class Approach. AB - Identifying preclinical Alzheimer's disease (AD) is an important step toward developing approaches to early treatment and dementia prevention. We applied latent class analysis (LCA) to 10 baseline neuropsychological assessments for 1,345 participants from Einstein Aging Study. Time-to-event models for all-cause dementia and AD were run examining events in 4-year intervals. Five classes were identified: Mixed-Domain Impairment (n = 107), Memory-Specific Impairment (n = 457), Average (n = 539), Frontal Impairment (n = 118), and Superior Cognition (n = 124). Compared to the Average class, the Mixed-Domain Impairment and Memory Specific Impairment classes were at higher risk of incident all-cause dementia and AD in the first 4 years from baseline, while the Frontal Impairment class was associated with higher risk between 4 and 8 years of follow-up. LCA identified classes which differ in cross-sectional cognitive patterns and in risk of dementia over specific follow-up intervals. PMID- 30282368 TI - Reappraisal of Abeta40 and Abeta42 Peptides Measurements in Cerebrospinal Fluid of Patients with Alzheimer's Disease. AB - Cerebrospinal fluid (CSF) biomarkers are currently included in the diagnostic criteria for Alzheimer's disease (AD), in particular, decreased concentrations of amyloid-beta peptide 1-42 (Abeta42) in the CSF, coupled with increased levels of tau and phosphorylated tau proteins, are supportive of AD diagnosis. To date, the quantification of Abeta42 levels with antibody-dependent immunoassay shows a marked variability among different laboratories and is also affected by different pre-analytical factors, suggesting that part of Abeta42 peptides might be aggregated and thus undetected by antibodies. To bypass an antibody-dependent measurement, we determined the Abeta40 and Abeta42 levels by immunoblot. We analyzed CSF samples from 35 patients with clinical diagnosis of probable AD and from 15 age-matched normal controls; CSF Abeta levels were determined by two different ELISA kits and by immunoblot analysis. Abeta40 levels measured by ELISA were comparable to those obtained by immunoblot, whereas CSF concentrations of Abeta42 measured by ELISA were significantly lower compared to values obtained by immunoblot quantification. Biochemical analysis, following 1D- and 2D-PAGE analysis, showed that the qualitative composition of Abeta peptides in the CSF is similar in AD and controls but different from that of AD brain tissues. Moreover, sedimentation velocity in sucrose gradient of CSF and brain homogenate from AD demonstrated that Abeta42 in CSF is different from Abeta42 in brain in terms of solubility and aggregation state. PMID- 30282366 TI - Incidence and Prevalence of Antiepileptic Medication Use in Community-Dwelling Persons with and without Alzheimer's Disease. AB - BACKGROUND: Although antiepileptic drugs (AEDs) have a potential for adverse drug reactions in older populations, little is known about their use in relation to Alzheimer's disease (AD) diagnosis. OBJECTIVES: In this study, we investigated the incidence and prevalence of AED use in relation to AD diagnosis. METHODS: The MEDALZ-study includes all Finnish persons who received clinically verified AD diagnoses (n = 70,718) during 2005-2011 and a matched comparison cohort without AD (n = 70,718). AD diagnoses were identified from the Special Reimbursement Register. We used the Prescription Register to identify dispensed AEDs. Incident AED users were identified with a one-year washout period 9-10 years before AD diagnosis, and incidence rates per 100 person-years were calculated for each six month period from nine years before to five years after AD diagnosis. Prevalence was assessed as proportion using AEDs during each six-month time period for incident use. RESULTS: Persons with AD were more likely to use AEDs during the study period (4.3%) than persons without AD (3.2%). The incidence and prevalence of AED use was higher among persons with AD and increased around the time of AD diagnosis. Epilepsy diagnoses did not explain these differences. Persons with AD were more likely to use older AEDs. CONCLUSION: Our study highlights the need to balance effective symptom control with the possible risks of treatment. PMID- 30282369 TI - Genetic Risk of Alzheimer's Disease: Three Wishes Now That the Genie is Out of the Bottle. AB - The availability and increasing popularity of direct-to-consumer genetic testing for the presence of an APOE4 allelle led the Alzheimer's Foundation of America Medical, Scientific and Memory Screening Advisory Board to identify three critical areas for attention: 1) ensure consumer understanding of test results; 2) address and limit potential negative consequences of acquiring this information; and 3) support linking results with positive health behaviors, including potential clinical trial participation. Improving access to appropriate sources of genetic counseling as part of the testing process is critical and requires action from clinicians and the genetic testing industry. Standardizing information and resources across the industry should start now, with the input of consumers and experts in genetic risk and health information disclosure. Direct to-consumer testing companies and clinicians should assist consumers by facilitating consultation with genetic counselors and facilitating pursuit of accurate information about testing. PMID- 30282371 TI - France Will No More Reimburse Available Symptomatic Drugs Against Alzheimer's Disease. AB - The French Minister of Health published a decree on May 29th of 2018 removing the drugs used to fight against symptoms due to Alzheimer's disease (donepezil, rivastigmine, galantamine, memantine) from the list of available reimbursed drugs. This follows the advice delivered by the High Authority for Health in 2016 and 2018 stating an "insufficient medical benefit and dangerousness because of significant side effects". The main French scientific and medical societies and professional associations want to state here their deep disagreement regarding this unfair decision. The evidence-based medicine related to these drugs reaches a high level in literature, whereas the clinical relevance of these treatments must be considered with co-prescription of psychosocial interventions and related approaches. As no serious pharmacovigilance signal has been provided by health authorities, the ratio of benefits/risks favors these drugs. PMID- 30282372 TI - Tetrabenazine Treatment Patterns and Outcomes for Chorea Associated with Huntington Disease: A Retrospective Chart Review. AB - BACKGROUND: Huntington disease (HD) is a neurodegenerative disorder characterized by motor impairments (including chorea), along with behavioral, psychiatric, and cognitive symptoms. Tetrabenazine was the first US Food and Drug Administration (FDA)-approved treatment for chorea related to HD. OBJECTIVE: To examine pharmacologic treatment patterns among patients using tetrabenazine, including reasons for treatment initiation, non-initiation, dose adjustments, and discontinuation, and to quantify the burden of chorea based on healthcare resource utilization. METHODS: In this retrospective patient chart review, neurologists were recruited from the Medefield (http://www.medefield.com) opt-in panel, and selected <=5 medical charts based on the criteria provided and abstracted data on demographics, disease history, healthcare resource use, and treatment patterns. RESULTS: 138 neurologists participated and 512 HD patient charts were reviewed. Among these patients, 26.4% did not initiate tetrabenazine. Most HD patients (66.5%) received a tetrabenazine dose <=50 mg. The most common reasons for stopping upward titration were optimal chorea control (55.5%), intolerability of higher doses (31.2%), and reaching the maximum recommended dosage despite suboptimal chorea control (11.4%). Chorea severity and non persistence to tetrabenazine were associated with increased emergency room visits, hospitalizations, and days hospitalized. CONCLUSIONS: Although tetrabenazine was the sole FDA-approved treatment for HD chorea until April 2017, more than one-quarter of respondents never initiated therapy. Tetrabenazine dosing was lower than predicted, and many patients experienced adverse symptoms of intolerability at high doses. New safer and more tolerable treatment options, such as deutetrabenazine, may improve treatment outcomes and reduce healthcare resource use. PMID- 30282370 TI - Tau Protein Dysfunction after Brain Ischemia. AB - Brain ischemia comprises blood-brain barrier, glial, and neuronal cells. The blood-brain barrier controls permeability of different substances and the composition of the neuronal cells 'milieu', which is required for their physiological functioning. Recent evidence indicates that brain ischemia itself and ischemic blood-brain barrier dysfunction is associated with the accumulation of neurotoxic molecules within brain tissue, e.g., different parts of amyloid beta protein precursor and changed pathologically tau protein. All these changes due to ischemia can initiate and progress neurodegeneration of the Alzheimer's disease-type. This review presents brain ischemia and ischemic blood-brain barrier as a trigger for tau protein alterations. Thus, we hypothesize that the changes in pattern of phosphorylation of tau protein are critical to microtubule function especially in neurons, and contribute to the neurodegeneration following brain ischemia-reperfusion episodes with Alzheimer's disease phenotype. PMID- 30282374 TI - How to Interpret Abnormal Findings of Spirometry and Manometry in Myotonic Dystrophies? AB - BACKGROUND/AIM: Pulmonary function tests are used for screening respiratory insufficiency in patients with myotonic dystrophy (DM). We analysed the agreement between two different approaches in assessment of abnormal findings of forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP), in DM patients. METHODS: We used Cohen's kappa- and Bangdiwala's B- statistic to compare the agreement between different cut-off values recommended by experts (ENMC) and the cut-off values based on the reference range (RR). We further analysed their sensitivity (Sn) and specificity (Sp) in detecting symptoms associated with respiratory insufficiency. RESULTS: The observed agreement was: 1) for FVC: kappa= -0.002, B = 0.406; 2) for FEV1: kappa= 0.944, B = 0.946; 3) for MIP: kappa= 0.625, B = 0.674; and 4) for MEP: kappa= 0.241, B = 0.373. Overall, RR cut-off values showed higher sensitivity, whereas the ENMC values showed higher specificity in detecting symptoms of respiratory involvement. CONCLUSIONS: The two approaches showed perfect agreement in assessment of FEV1, substantial agreement for MIP, and weak agreement for FVC and MEP. RR is an established method of assessment for spirometry and should be favoured because it takes variability within the population into account. Further development and validation of regression equations for RR calculations of predicted maximal respiratory pressures, with corresponding lower limits of normal, is required.The B statistic is more robust in assessing agreement between two diagnostic methods, resolving the issue of the kappa paradox. PMID- 30282373 TI - Disability and Contextual Factors in Patients with Amyotrophic Lateral Sclerosis A Three-Year Observational Study. AB - BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by muscle weakness and wasting. Observational natural history studies can give information on body function/structure impairments, activity limitations and participation restrictions, i.e. disability. Information needed to plan and develop care and support. OBJECTIVE: To describe and explore disease severity and impairments, activity limitations, participation restrictions and contextual factors over time. In specific, to explore concurrent presence of cognitive impairment, fatigue, anxiety, depression and pain, and whether these impairments were related to disease severity. METHODS: In this three-year observational study, 60 patients with ALS were included at baseline. Follow-ups were performed every 6 months unless participants had deceased or declined participation. Data was collected from medical records, and by study specific and standardized questionnaires administrated during home visits. RESULTS: Regardless of disease severity; fatigue, anxiety, depression and pain were present in patients with ALS at each data collection. Approximately one third experienced two or more of these impairments concurrently, i.e. at the same time point. Cognitive impairment could not be assessed in many patients due to their physical impairments. Disease severity was not associated with fatigue, anxiety, depression or pain. CONCLUSIONS: Patients with ALS need, throughout the course of the disease, to be regularly screened for commonly present impairments, activity limitations and participation restrictions so that person-centered interventions can be applied at the right time. PMID- 30282376 TI - Selective prophylactic solvent-detergent plasma and cryoprecipitate transfusion to prevent intraventricular hemorrhage in extreme preterm infants: A case historical control. AB - BACKGROUND: Contradictory evidence exists whether a prophylactic coagulation factor transfusion in the first hours of life (HOL) prevents intraventricular hemorrhage (IVH) in extreme preterm infants (EPI, <28 weeks gestation). We aimed to determine whether selective prophylactic solvent-detergent plasma and cryoprecipitate transfusion within 12 hours of life (SP-SDP/Cryoprecipitate-T) could prevent IVH in EPI. METHOD: This is a retrospective analysis, case historical control, of prospectively collected data from a pre-existing electronic neonatal database at a Saudi tertiary neonatal intensive care unit. We compared the IVH rate in EPI born in the first 4 years (Jan 2010-Dec 2013) of the SP-SDP/Cryoprecipitate-T period with that of EPI born during the last 4 years (Jan 2006-Dec 2009) of the rescue SDP/Cryoprecipitate-T period. RESULTS: The IVH rate was lower in the SP compared to the rescue- SDP/Cryoprecipitate-T period (30.8% versus 51.2%, odds ratio 0.42, 95% confidence interval 0.21, 0.88, p = 0.02). This difference remained significant after controlling for six other IVH risk factors. CONCLUSIONS: Early SP-SDP/Cryoprecipitate-T may reduce the IVH rate in EPI. A large multicenter clinical trial is required for confirm the short and long-term benefit and risk of this intervention. Until then, early SP SDP/Cryoprecipitate-T may be considered by an institution with a persistently high IVH rate. PMID- 30282375 TI - Home-Based Monitoring of Pulmonary Function in Patients with Duchenne Muscular Dystroph. AB - BACKGROUND: Loss of pulmonary function is a main cause of early morbidity and mortality in patients with Duchenne muscular dystrophy (DMD). Standard of care guidelines recommend regular assessment of pulmonary function by hospital-based spirometry to detect onset and monitor progression of pulmonary function decline. OBJECTIVE: To assess the feasibility of home-based monitoring of pulmonary function by a hand-held device (HHD) in adolescent and adult patients with DMD over a period of 12 months. METHODS: In the phase III randomized placebo controlled DELOS trial in 10-18 year old DMD patients, peak expiratory flow (PEF) measurements were collected weekly at home by the patient (assisted by parent/caregiver) using a peak flow meter HHD. Adherence to the use of the HHD was assessed and 12-month changes in PEF as percent of predicted (PEF% p) for the idebenone (N = 31) and the placebo treatment groups (N = 33) from HHD-derived data were compared to results from hospital-based spirometry. RESULTS: A total of 2689 individual HHD assessments were analysed. Overall adherence to the use of the HHD over the course of the 12-month study duration was good (75.9%, SD 21.5%) and PEF% p data obtained at the same day by HHD and standard spirometry correlated well (Spearman's rho 0.80; p < 0.001). Several analysis methods of HHD derived data for PEF% p consistently demonstrate that idebenone treatment slowed the decline in PEF% p compared to placebo, which supports the statistically significant difference in favour of idebenone for PEF% p measured by standard spirometry. CONCLUSIONS: This study demonstrates that home-based monitoring of pulmonary function in adolescent patients with DMD using a HHD is feasible, provides reliable data compared to hospital-based spirometry and is therefore suitable for use in clinical practice and for clinical trials. PMID- 30282379 TI - Recovery from apraxic deficits and its neural correlate. AB - BACKGROUND AND OBJECTIVE: Apraxia is a deficit of motor cognition leading to difficulties in actual tool use, imitation of gestures, and pantomiming object use. To date, little data exist regarding the recovery from apraxic deficits after stroke, and no statistical lesion mapping study investigated the neural correlate of recovery from apraxia. Accordingly, we here examined recovery from apraxic deficits, differential associations of apraxia task (imitation vs. pantomime) and effector (bucco-facial vs. limb apraxia) with recovery, and the underlying neural correlates. METHODS: We assessed apraxia in 39 patients with left hemisphere (LH) stroke both at admission and approximately 11 days later. Furthermore, we collected clinical imaging data to identify brain regions associated with recovery from apraxic deficits using voxel-based lesion-symptom mapping (VLSM). RESULTS: Between the two assessments, a significant recovery from apraxic deficits was observed with a tendency of enhanced recovery of limb compared to bucco-facial apraxia. VLSM analyses revealed that within the lesion pattern initially associated with apraxia, lesions of the left insula were associated with remission of apraxic deficits, whereas lesions to the (inferior) parietal lobe (IPL; supramarginal and angular gyrus) and the superior longitudinal fasciculus (SLF) were associated with persistent apraxic deficits. CONCLUSIONS: Data suggest that lesions affecting the core regions (and white matter) of the fronto-parietal praxis network cause more persistent apraxic deficits than lesions affecting other regions (here: the left insula) that also contribute to motor cognition and apraxic deficits. PMID- 30282380 TI - Alterations in mitochondrial membrane potential in peripheral blood mononuclear cells in Parkinson's Disease: Potential for a novel biomarker. AB - BACKGROUND: Progressive apoptosis in the dopaminergic neurons of substantia nigra lead to Parkinson's disease. Since neurons require substantially higher supply of energy, their mitochondria have a pivotal status in neuronal survival. These organelles have a key role to play in apoptosis and any impairment thereof may lead to apoptosis mediated cell death. OBJECTIVES: To evaluate and compare the mitochondrial membrane potential (Deltapsi) in Parkinson's disease patients and healthy controls. METHODS: We evaluated the mitochondrial membrane potential (Deltapsi) in the peripheral blood mononuclear cells by Flow cytometry using a lipophillic cationic dye JC-1 in Parkinson's disease patients (N = 61) and healthy controls (N = 37). RESULTS: JC-1 fluorescence was measured and represented as percentage positivity i.e., Mean+/-SEM in FL-2 (representing non apoptotic aggregates) and FL-1 (indicating apoptotic cell population having depolarized or damaged mitochondria) channels. The ratio of % FL-2 and % FL-1, which is an indicator of cellular mitochondrial membrane potential, was found to be significantly higher in healthy controls (Mean+/-SEM = 60.48+/-18.42) as compared to patients (Mean+/-SEM = 24.30+/-4.671) in both stimulated and unstimulated conditions. CONCLUSIONS: Mitochondrial membrane potential is altered and hence its evaluation in peripheral blood mononuclear cells may serve as an early marker of apoptosis in PD and, therefore, may pave way for early interventions. Since Deltapsi has a role in the maintenance of electrochemical gradient, the disruption of which may lead to neuronal apoptosis, Deltapsi is intricately nested within etiopathogenesis of PD and may prove to be useful in design of diagnostics, prognostics and therapeutics for PD. PMID- 30282381 TI - Egg yolk immunoglobulins' impact on experimental periodontitis caused by Porphyromonas gingivalis. AB - BACKGROUND: Periodontitis is a chronic inflammatory disease caused by Porphyromonas gingivalis that leads to a series of periodontal tissue injuries. Egg yolk immunoglobulins (IgY) is procuded in egg yolk and inhibits P. gingivalis. OBJECTIVE: The aim was to evaluate the effect of IgY on experimental periodontitis caused by P. gingivalis. METHODS: The second molars of rats were ligatured using medical 5-0 silk and smeared with P. gingivalis to induce experimental periodontitis. Then, the rats were smeared with 2 mL IgY solutions or 0.9% NaCl in the oral cavity for up to 4 wk. The scores for gingival index, plaque index and probe on bleeding, the levels of IL-6 and TNF-alpha, X-ray radiography and histology were used to determine the efficacy of the IgY on experimental periodontitis. RESULTS: The clinical indices improved; the levels of IL-6 and TNF-alpha were significantly (p< 0.05) decreased; the X-rays and histomorphological observations suggested that the periodontal inflammation and periodontitis were alleviated compared to the control. CONCLUSIONS: IgY showed significant effects on anti-inflammatory, anti-coaggregation activity, and protected against alveolar bone loss. Therefore, it had a beneficial effect on preventing experimental periodontitis caused by P. gingivalis. PMID- 30282382 TI - The effects of a posterior superior iliac spine support device on upper trunk acceleration during gait in individuals with flat lumbar back posture. AB - BACKGROUND: The orientation of the pelvis is of particular importance to the sagittal curve of the spine and has geometric relationships with the top of the spine and lumbar lordosis. Changes in spinal shape or disruptions of sagittal balance in the spine, such as a flattened lumbar spine, have significant negative effects. OBJECTIVE: The aim of this study was to investigate the effects of the posterior superior iliac spine support device (PSD) on upper trunk acceleration during gait in individuals with flat lumbar back posture. METHODS: In total, 10 young male subjects with reduced lumbar lordosis (global lumbar lordosis angle (T10-S2): <-20?) were recruited for this study. Participants walked 7 m with and without wearing a PSD at a self-selected speed while fitted with an accelerometer attached over the T7 spinous process. RESULTS: The normalized AP acceleration of T7 with PSD (40.57 +/- 11.22%) was significantly higher than those without PSD (37.10 +/- 10.46%, p= 0.035). CONCLUSIONS: We found that wearing the PSD immediately improved pelvic physiological movement during walking in individuals with lumbar flat back posture. Our findings may help healthcare professionals manage flat back posture in asymptomatic younger individuals. PMID- 30282383 TI - The occlusion effect in bone conducted cVEMP. AB - BACKGROUND: Vestibular evoked myogenic potentials (VEMP) are transient alteration in tonic activity of muscles elicited by auditory stimulation of the otolithic organs of the ear. VEMP can be triggered by auditory stimulation via air or bone conduction. Occlusion of the external auditory meatus has long been known to decrease thresholds for sound perception medicated by the cochlea. OBJECTIVE: Proof that the occlusion effect is present for bone conducted (BC) cervical VEMPs (cVEMP). METHODS: Measurement of the thresholds and raw amplitudes of BC-VEMPs in twenty healthy adults with the external auditory canal open and occluded. RESULTS: Thresholds for BC-VEMPs were similar for the open vs. the occluded condition. However, amplitudes were statistically significantly higher in the occluded (average 76.34MUV) vs. open group (average 69.9MUV). CONCLUSIONS: The occlusion effect is present in cVEMPs. This finding, described herein for the first time, has a number of clinical implications such as the surgically altered ear and the use of occluding hearing aids.

AB - : On July 12, 2018, the Centers for Medicare and Medicaid Services (CMS) released the proposed 2019 Medicare physician fee schedule and quality payment program, combining these 2 rules for the first time. This occurred in a milieu of changing regulations that have been challenging for interventional pain management specialists. The Affordable Care Act (ACA) continuous to be amended by multiple administrative changes. This July 12th rule proposes substantial payment changes for evaluation and management (E&M) services, with documentation requirements, and blending of Level II to V CPT codes for E&M into a single payment. In addition, various changes in the quality payment program with liberalization of some metrics have been published. Recognizing that there are differing impacts based on specialty and practice type, as a whole interventional pain management specialists would likely see favorable reimbursement trends for E&M services as a result of this proposal. Moreover, in comparison with recent CMS final ruling, this proposed rule has relatively limited changes in procedural reimbursement performed in a facility or in-office setting.CMS, in the new rule, has proposed an overhaul of the E&M documentation and coding system ostensibly to reduce the amount of time physicians are required to spend inputting information into patients' records. The new proposed rule blends Level II to V codes for E&M services into a single payment of $93 for office outpatient visits for established patients and $135 for new patient visits. This will also have an effect with blended payments for services provided in hospital outpatients. CMS also has provided additional codes to increase the reimbursement when prolonged services are provided with total reimbursement coming to Level V payments. Interventional pain management-centered care has been identified as a specialty with complexity inherent to E&M associated with these services. Among the procedural payments, there exist significant discrepancies for the services performed in hospitals, ambulatory surgery centers (ASCs), and offices. A particularly egregious example is peripheral neurolytic blocks, which is reimbursed at 1,800% higher in hospital outpatient department (HOPD) settings as compared with procedures done in the office. The majority of hospital based procedures have faced relatively small cuts as compared with office based practice. The only significant change noted is for spinal cord stimulator implant leads when performed in office setting with 19.2% increase. However, epidural codes, which have been initiated with a lower payment, continue to face small reductions for physician portion.This review describes the effects of the proposed policy on interventional pain management reimbursement for E&M services, procedural services by physicians and procedures performed in office settings.

PMID- 30282388 TI - Efficacy Assessment of Radiofrequency Ablation as a Palliative Pain Treatment in Patients with Painful Metastatic Spinal Lesions: A Systematic Review. AB - BACKGROUND: Metastatic spinal lesions are difficult-to-treat entities that are most commonly associated with pain and severely reduced health-related quality of life (HRQoL). Within the last 5 to 10 years, radiofrequency ablation (RFA) has emerged as an option in the palliative treatment of vertebral metastases. OBJECTIVES: Our review aims to evaluate the clinical effectiveness and safety of RFA, mostly in combination with vertebroplasty, in patients with painful vertebral metastases. STUDY DESIGN: The design of this study is a systematic review. METHODS: We conducted a systematic literature search and a manual search of 5 databases in December 2016. The review applied a methodological framework based on the HTA Core Model(r). Data on each selected outcome category were synthesized according to the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) scheme. Risk of bias was assessed using the Institute of Health Economics (IHE) Risk of Bias checklist for case series. RESULTS: We identified 299 citations. After applying the inclusion criteria, a total of 9 studies (4 prospective and 5 retrospective studies) were determined to be eligible. These studies included a total of 583 patients with vertebral metastases who were treated with RFA and, in most cases, received an additional vertebroplasty treatment (n = 437). The studies were categorized as having a moderate to high risk of bias. The strength of evidence was found to be "very low" for safety outcomes and could not be assessed for efficacy outcomes. Current evidence suggests that RFA leads to significant pain reduction. Furthermore, no major complications occurred when using RFA. LIMITATIONS: A major concern is the low number of included patients and heterogeneity of study characteristics in most of the studies. The low number of patients also impeded comparison of the effectiveness of RFA alone to RFA in combination with vertebroplasty. CONCLUSION: According to the available evidence, RFA may be safe and effective, especially for patients with painful vertebral metastases who show contraindications or unresponsiveness to conventional therapies (e.g., radiation) or for those who are at risk of tumor progression.

PMID- 30282389 TI - Comparison of Clinical Efficacy Between Transforaminal and Interlaminar Epidural Injections in Lumbosacral Disc Herniation: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Epidural injection (EI) is used to treat back or radicular pain from lumbosacral disc herniation (LDH). Although several reports have stated that the transforaminal approach in EI (TFEI) has an advantage in target specificity and yields better clinical efficacy than the interlaminar approach in EI (ILEI), other studies have indicated that the clinical efficacy of ILEI was not inferior to that of TFEI and that ILEI also has the ability to spread medication into the ventral space to a degree similar to that of TFEI. There has been controversy about whether TFEI is superior to ILEI in clinical efficacy. OBJECTIVES: This systematic review and meta-analysis aimed to investigate whether TFEI is more useful than ILEI for achieving clinical outcomes in patients with LDH. STUDY DESIGN: A systematic review and meta-analysis using a random effects model on randomized controlled studies (RCT). METHODS: A literature search was performed in MEDLINE, EMBASE, Cochrane review, and KoreaMed for studies published from January 1996 until July 2017. From those found fulfilling the search criteria, manuscripts that compared the clinical efficacy of steroids and control agents, such as local anesthetics or saline, in terms of pain control and functional improvement were included in this study. Exclusion criteria included a previous history of lumbosacral surgery, non-specific low back pain, severe spinal stenosis, and severe disc degeneration. After reviewing titles, abstracts, and the full text of 6,711 studies; 12 studies were included in the qualitative synthesis. Data including pain scores, functional scores, and follow-up period were extracted from 10 studies and analyzed using a random effects model to obtain effect size and its statistical significance. The quality and level of evidence were analyzed in accordance with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. RESULTS: In terms of pain control, TFEI showed significantly better short-term (2 weeks to 1 month) outcomes and slightly favorable long-term (4 - 6 month) outcomes, but without significance, in comparison with ILEI. In terms of functional improvement, TFEI also showed favorable short- and long-term outcomes, but without significance, in comparison with ILEI. TFEI had target specificity, required no additional cost and resources, and had equal applicability to ILEI. However, TFEI was more associated with a higher frequency of discomfort or adverse events during the procedure. Overall, better results were reported with TFEI over ILEI, but with low-grade evidence due to the inconsistency and imprecision of the selected studies. LIMITATION: Analyses of safety or adverse effects could not be performed due to a lack of available data from the included studies. CONCLUSIONS: Based on low-grade evidence, TFEI showed significantly better short-term pain control and slightly favorable outcomes in long-term pain reduction and short- and long-term functional improvement in comparison with ILEI.

PMID- 30282390 TI - Comparison of Clinical Efficacy of Epidural Injection With or Without Steroid in Lumbosacral Disc Herniation: A Systematic Review and Meta-analysis. AB - BACKGROUND: Epidural injection is performed for treatment of back and radicular pain in patients with lumbosacral disc herniation (LDH). Steroids are usually administered to effectively remove inflammatory mediators, and local anesthetics or saline also contribute to pain reduction by washing out chemical mediators or blocking the nociceptor activity. Controversy exists regarding whether steroids produce superior clinical effects compared with local anesthetics or saline. OBJECTIVES: This study investigated whether epidural injection of steroids produces better clinical effects than local anesthetics or saline in the treatment of LDH. STUDY DESIGN: A literature search was performed in MEDLINE, EMBASE, Cochrane review, and KoreaMed for studies published from January 1996 until July 2017. From among the studies fulfilling the search criteria, those that compared the clinical efficacy of steroids and control agents, such as local anesthetics or saline, in terms of pain control and functional improvement were included in this study. Exclusion criteria included a previous history of lumbosacral surgery, non-specific low back pain, severe spinal stenosis, and severe disc degeneration. SETTING: A systematic review and meta-analysis using a random effects model on randomized controlled studies (RCTs). METHODS: After reviewing titles, abstracts, and full texts of 6,711 studies that were chosen following removal of duplicates after the initial database search, 15 randomized controlled studies were included in our qualitative synthesis. Data including pain score, functional score, and follow-up period were extracted from 14 studies and analyzed using a random effects model to calculate the effect size and its corresponding statistical significance. Quality and level of evidence were established in accordance with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. RESULTS: Steroids and local anesthetics were shown to be effective. Steroid showed significantly better pain control than control agents at 1 month, 3 months, and 6 months. The superiority of steroid in pain control was more prominent at one month, but diminished from 3 months to 1 year, showing no significant superiority in terms of mean difference, With respect to functional score, no significant difference was observed between steroids and control agents. The subgroup analysis showed that steroid revealed significant superiority in pain and functional score at 1 month to saline rather than local anesthetics. Generally, the quality of included studies was evaluated as high-grade, but the evidence level was determined to be moderate, due to inconsistencies. LIMITATION: Analyses of safety or adverse effects could not be performed due to a lack of available data from the included studies. CONCLUSIONS: Steroid is recommended over local anesthetics or saline for pain control in patients with LDH, with a weak strength of recommendation. The superiority of steroids was remarkable, especially at relatively short-term follow-ups, and maintained until the 1 year follow-up. The clinical benefits of steroids at 1 month were more prominent when compared with saline, than when compared with local anesthetics.

PMID- 30282391 TI - Effectiveness and Safety of High-Voltage Pulsed Radiofrequency to Treat Patients with Primary Trigeminal Neuralgia: A Multicenter, Randomized, Double-Blind, Controlled Study Protocol. AB - BACKGROUND: Trigeminal neuralgia (TN) is a neurological syndrome characterized by paroxysmal, lightning-like, severe pain in the facial area innervated by the trigeminal nerve. Patients who do not respond well to drug treatment can undergo a nerve block, a traditional conservative treatment. Pulsed radiofrequency (PRF) is a nondestructive pain intervention technique. However, its treatment effectiveness for TN has rarely been reported and remains controversial among scholars. A recent single-center preliminary clinical study showed that high voltage PRF was significantly effective in the treatment of TN. However, whether high-voltage PRF is a viable pain treatment option for TN patients who are unresponsive to drug treatment must still be confirmed with standardized clinical studies by utilizing conservative nerve block treatment as a control. OBJECTIVE: To compare the effectiveness and safety of high-voltage PRF and nerve block for primary TN patients who have failed to respond to pharmacological treatment and who are seeking a better non-surgical treatment option. STUDY DESIGN: Prospective, multicenter, randomized, double-blind, controlled clinical trial. SETTING: Three interventional pain management centers in Beijing, China. METHODS: The study will include 134 consecutive patients with primary TN who have failed to respond to drug treatment. The patients will be randomly assigned to 2 groups, the nerve block group and the PRF group. The nerve block group will be slowly injected with 1.4 mL of a mixture of dexamethasone and lidocaine after 360 s of sham PRF treatment, and 0.5 mL of normal saline will be administered before the needle is withdrawn. The PRF group will undergo 360 s of 42 degrees C PRF treatment at the highest output voltage that the patients can tolerate, after which the patients will be injected with the same concentration and volume of lidocaine and normal saline that the nerve block group receives. The Barrow Neurological Institute (BNI) pain intensity scale will be used to assess the degree of pain relief before and after the treatment. RESULTS: The effectiveness and safety of high-voltage PRF and nerve block to treat TN will be analyzed to determine significant differences in pain relief and functional improvement. The primary efficacy outcome measure is the response rate at one-year post-operation (BNI I-III/total number of cases*100%). Secondary efficacy outcome measures include the response rate at postoperative day 1, week 1, week 2, month 1, month 3, month 6 and year 2, the patient satisfaction score (PSS) at various time points, the dosage of antiepileptic drugs (milligrams per day), and information regarding patients with a BNI score of IV or V who switch to other therapies. LIMITATIONS: The effects of the waveform, treatment duration, frequency and other parameters of PRF deserve further investigation. CONCLUSIONS: This is the first multicenter, double-blind, randomized controlled study to compare the efficacy and safety of PRF and nerve block to treat TN patients who have failed to respond to drug treatment. Moreover, the value of PRF in TN treatment may need to be clinically clarified with evidence-based medical support and other advanced studies.

PMID- 30282392 TI - Preemptive Analgesia with Parecoxib in Total Hip Arthroplasty: A Randomized, Double-Blind, Placebo-Controlled Trial. AB - BACKGROUND: Total hip arthroplasty (THA) is a well-accepted surgical treatment for terminal hip diseases. OBJECTIVE: To evaluate the effect of preemptive analgesia with parecoxib in patients undergoing primary unilateral THA. STUDY DESIGN: A randomized, double-blind, placebo-controlled study. SETTING: This study was conducted at Peking Union Medical College Hospital and Beijing Jishuitan Hospital in Beijing, China. METHODS: A total of 94 patients scheduled for primary unilateral THA in 2 centers (Peking Union Medical College Hospital and Beijing Jishuitan Hospital) were randomly assigned to receive 40 mg parecoxib (n = 48) or 0.9% normal saline solution (n = 46) 30 minutes before incision. All patients received standardized intravenous patient-controlled analgesia (PCA) postoperatively. Preoperative baseline data, surgery-related conditions, postoperative Visual Analog Scale (VAS) pain score, cumulative narcotic consumption of PCA, and complications were compared between the parecoxib group and the placebo group. RESULTS: There were no significant differences in postoperative VAS pain score, cumulative narcotic consumption of PCA, proportion of analgesic remedy, and complications between the 2 groups. LIMITATIONS: Only a single dose of parecoxib was used without including a dose-dependent control group. CONCLUSION: A single dose of parecoxib 30 minutes before incision did not provide effective preemptive analgesia for the management of postoperative pain after primary unilateral THA. The possible effect of preemptive analgesia with parecoxib needs further investigation. KEY WORDS: Total hip arthroplasty, pain, parecoxib, COX-2 selective inhibitor, preemptive analgesia, clinical trial, patient-controlled analgesia, analgesics. PMID- 30282393 TI - Comparison of Efficacy of Lateral Branch Pulsed Radiofrequency Denervation and Intraarticular Depot Methylprednisolone Injection for Sacroiliac Joint Pain. AB - BACKGROUND: Sacroiliac joint dysfunctional pain has always been an enigma to the pain physician, whether it be the diagnosis or the treatment. Diagnostic blocks are the gold standard way to diagnose this condition. Radiofrequency neurotomy of the nerves supplying the sacroiliac joint has shown equivocal results due to anatomical variation. Intraarticular depo-steroid injection is a traditional approach to treating sacroiliac joint pain. For long-term pain relief, however, lesioning the sacral lateral branches may be a better approach. OBJECTIVE: This study compared the efficacy of intraarticular depo-methylprednisolone injection to that of pulsed radiofrequency ablation for sacroiliac joint pain. STUDY DESIGN: This study used a randomized, prospective design. SETTING: Thirty patients with diagnostic block-confirmed sacroiliac joint dysfunctional pain were randomly assigned to 2 groups. One group received intraarticular methylprednisolone and another group underwent pulsed radiofrequency of the L4 medial branch, the L5 dorsal rami, and the lateral sacral branches. RESULTS: Reduction in Numeric Rating Scale (NRS) for pain at 1 month post-procedure remained similar in Group A, while in Group B few patients reported a further decrease in the NRS score (3.333 +/- 0.4880 and 2.933 +/- 0.5936, respectively). At 3 months post-procedure, the NRS score began to rise in most patients in group A, while in Group B, the NRS score remained the same since the last visit (4.400 +/- 0.9856 and 3.067 +/- 0.8837, respectively). At 6 months post-procedure, the NRS score began to rise further in most patients in group A. In Group B, the NRS score remained the same in most of the patients since the last visit (5.400 +/- 1.549 and 3.200 +/- 1.207). There was a marked difference between the 2 groups in Oswestry Disability Index (ODI) scores at 3 months post-procedure (Group A, 12.133 +/- 4.486 vs Group B, 9.133 +/- 3.523) and at 6 months post-procedure there was a significant (P = 0.0017) difference in ODI scores between Group A and Group B (13.067 +/- 4.284 and 8.000 +/- 3.703, respectively). Global Perceived Effect (GPE) was assessed in both groups at 3 months post-procedure Only 33.3% (Confidence Interval (CI) of 11.8- 61.6 ) of patients in Group A had positive GPE responses whereas in Group B, 86.67% (CI of 59.5- 98.3 ) of patients had positive GPE responses. At 6 months post-procedure, the proportion of patients with positive GPE declined further in Group A, while in Group B, positive GPE responses remained the same (20% with a CI of 4.30- 48.10 and 86.67% with a CI of 59.5- 98.3, respectively ). LIMITATIONS: Small sample size. CONCLUSION: This comparative study shows that pulsed radiofrequency denervation of the L4 and L5 primary dorsal rami and S1-3 lateral branches provide significant pain relief and functional improvement in patients with sacroiliac joint pain.

PMID- 30282394 TI - Low Volume Neurolytic Retrocrural Celiac Plexus Block for Visceral Cancer Pain: Retrospective Review of 507 Patients with Severe Malignancy Related Pain Due to Primary Abdominal Cancer or Metastatic Disease. AB - BACKGROUND: Abdominal pain from primary cancer or metastatic disease is a significant cause of pain for patients undergoing treatment for the disease. Patient's pain may be resistant to conventional analgesics. The need for timely pain relief in order to facilitate further care in the cancer treatment plan should be a priority. OBJECTIVES: The aim of this retrospective observational review was to assess the relief given with a low volume neurolytic retrocrural celiac plexus nerve block, the duration of the procedure, the duration of relief, the reduction in daily opioid consumption, and the improvement of quality of life in a patient suffering from incapacitating abdominal pain due to primary abdominal malignancy or abdominal metastatic disease. Patients were given a neurolytic celiac plexus block without previous diagnostic block due to multiple comorbidities. STUDY DESIGN: This is a retrospective, observational study. METHODS: Five hundred and seven patients were studied and data at 5 months for 455 patients were retained at the end of the review. They were evaluated in the pain center prior to and after the neurolytic retrocrural celiac plexus nerve block under fluoroscopic guidance. They were assessed on duration of procedure, pain scores (numeric rating scale 0-10), daily opioid consumption, quality of life improvement (simple yes or no question at 3 months) and routine follow-up during treatment for the cancer for 6 months or end of life. All data was gathered by extensive chart review and placed on a spreadsheet for analysis. RESULTS: Follow-up was completed 6 months after the procedure. Pain scores, daily opioid consumption, and quality of life showed improvement for the duration of the study. There was some return in pain during the fourth to sixth month due to disease progression and the anticipated duration of the neurolytic agent. Some short duration known side effects did occur. An initial vascular contrast uptake of 6.7% was noted during the procedure while utilizing digital subtraction angiography with fluoroscopy. LIMITATIONS: A larger sample size would be ideal, as well as, a prospective trial with a control group, but this is unrealistic in our patient population. A proven quality of life questionnaire would be beneficial. Comparing alcohol, phenol and radiofrequency thermocoagulation would be interesting to equate duration, effect, and side effects. CONCLUSION: Low volume neurolytic retrocrural celiac plexus nerve block with phenol is a safe procedure providing up to 6 months of pain relief and is an effective, well established, minimally time-consuming procedure for abdominal pain due to primary malignancy or metastatic spread.

PMID- 30282395 TI - A Retrospective Review of Spinal Radiofrequency Neurotomy Procedures in Patients with Metallic Posterior Spinal Instrumentation - Is it Safe? AB - BACKGROUND: Recent studies have shown that medial branch radiofrequency neurotomy (RFN) procedures done at the level of a pedicle screw can increase pedicle screw temperature, and it has been speculated that pedicle screw heating may cause thermal injury. There has been a limited amount of investigation into the real world safety profile of RFN procedures in patients with pedicle screws. OBJECTIVES: We aim to demonstrate that the occurrence of serious adverse events is rare for a medial branch RFN procedure completed at a level with metallic spinal hardware when performed according to the Spine Intervention Society practice standards. STUDY DESIGN: This study involved retrospective chart reviews of every patient who received an RFN procedure for spinal facet joint pain during the 5-year time period from 2012-2016. SETTING: The research took place within a single university-based interventional pain management center. METHODS: The study sample included 507 patient charts. Data collection included patient demographics, RF denervation sites at a level with metallic hardware, and all serious RF-related complications that could be attributable to heated metallic hardware. The research team developed medical-chart abstraction criteria for each of the following categorized complications: a) superficial burns, b) deep burns, c) denervation of dorsal ramus, d) denervation of ventral ramus, and e) coagulation of a spinal vascular structure. RESULTS: Of the 36 patients who met the inclusion criteria for this study, 43.6% were men and 56.4% were women. The mean age was 59.5 years old, with an age range of 25 to 87 years. There were a total of 56 ablations performed at a level with metallic spinal hardware, of which 11 were cervical, 44 were lumbar, and 1 was thoracic . There were zero documented complications found among our patient population in any of the 5 categories of serious complications. LIMITATIONS: As a retrospective chart review, this study was dependent on the availability and accuracy of medical records. Chart abstraction criteria for each outcome measure were developed by the research team without scientific testing. CONCLUSIONS: There have been no reported complications attributable to hardware temperature increases when performing medial branch RFNs at the level of a pedicle screw. For safety, it is important to use multiplanar fluoroscopic imaging techniques to ensure that the RFN cannula is not in contact with the pedicle screw.

PMID- 30282396 TI - Earlier Vertebroplasty for Osteoporotic Thoracolumbar Compression Fracture May Minimize the Subsequent Development of Adjacent Fractures: A Retrospective Study. AB - BACKGROUND: Percutaneous vertebroplasty (PVP) is widely used to treat osteoporotic vertebral compression fractures (OVCFs). The influence of timing (early vs. late) of PVP on the development of adjacent vertebral fractures (AVF) has rarely been discussed. OBJECTIVE: This study aimed to compare the incidence of AVF among patients who received early PVP (= 30 days after symptom onset, EPVP) or late PVP (> 30 days after symptom onset, LPVP) in the thoracolumbar region (T10 to L2) after a 1-year follow up. STUDY DESIGN: A retrospective cohort study. SETTING: Department of Orthopedic, an affiliated hospital of a medical university. METHODS: Patients who had single-level, T-score = -2.5 of lumbar bone mineral density (BMD), primary OVCF in the thoracolumbar region (T10 to L2) and who received PVP between July 2012 and June 2014 were included in the study. They were divided into early PVP and late PVP groups according to the interval between symptom onset and treatment. The risk factors associated with subsequent AVFs were analyzed. RESULTS: Of the 225 patients reviewed, 124 met the criteria and were followed for a minimum of 1 year. Eleven patients (14.1%) in the EPVP group (n = 78) and 18 patients (39.1%) in the LPVP group (n = 46) experienced an AVF during the first year following vertebroplasty. Outcomes were significantly better in patients with higher bone mineral density, lower cement volume, and without cement leakage (P < 0.01). Cox regression indicated an increase risk for AVF for LPVP, with an adjusted hazard ratio of 6.08 (95% confidence interval: 2.50-14.81). LIMITATION: The incidence of AVFs could be over estimated due to this being a retrospective study with a small case number and lack of either biomechanical study of intra-vertebral cement distribution by times to support the result. CONCLUSIONS: Compared with later interventions, PVP performed within 30 days after fracture development may be associated with a lower risk of adjacent fractures in the thoracolumbar region.

PMID- 30282397 TI - Variations in Interlaminar Epidural Steroid Injection Practice Patterns by Interventional Pain Management Physicians in the United States. AB - BACKGROUND: Previous surveys have identified variations in practice patterns related to epidural steroid injections. Since then, the United States Food and Drug Administration (FDA) has required the addition of drug warning labels for injectable corticosteroids. Updated evidence, as well as scrutiny from regulatory agencies, may affect practice patterns. OBJECTIVE: To provide an update on interlaminar epidural steroid injection (ILESI) practice patterns, we surveyed interventional pain management (IPM) physicians in the United States. STUDY DESIGN AND SETTING: This was a cross-sectional survey of IPM physicians in the United States. METHODS: A web-based survey was distributed to IPM physicians in the United States selected from the Accreditation Council for Graduate Medical Education accredited pain medicine fellowship program list as well as the American Society of Interventional Pain Physicians membership database. Physicians were queried about ILESI practices, including needle size, use of image guidance, level of injection, identification of the epidural space, and preference for injectate. RESULTS: A total of 249 responses were analyzed. All respondents used image guidance for ILESI. There were variations in needle size, use of contrast, number of fluoroscopic views utilized, technique for identifying the epidural space, and choice of injectate. LIMITATIONS: The response rate is a limitation, thus the results may not be representative of all United States IPM physicians. CONCLUSIONS: Though all respondents used image guidance for ILESI, variations in other ILESI practices still exist. Since the closure of this survey, a multi-society pain workgroup published recommendations regarding ESI practices. Our survey findings support the need for more evidence-based guidelines regarding ESI. KEY WORDS: Epidural injection, epidural steroids, survey, low back pain, neck pain, technique. PMID- 30282398 TI - Comparison of 3 Approaches to Percutaneous Epidural Adhesiolysis and Neuroplasty in Post Lumbar Surgery Syndrome. AB - BACKGROUND: Percutaneous epidural adhesiolysis and neuroplasty (PEAN) has been proven to be safe and effective in treating different spine pathologies, in particular post lumbar surgery syndrome (PLSS). OBJECTIVES: The purpose of this study was to compare the efficacy and complication rates of the 3 different PEAN anatomical approaches (caudal, S1 foraminal, and L5-S1 transforaminal) used to treat PLSS. STUDY DESIGN: This study used a case control, blind study. SETTING: The research took place at the pain clinic and interventional pain practice room at Asyut University Hospital, Assiut, Egypt. METHODS: Sixty consecutive PLSS patients were recruited and randomized into 3 groups (caudal, S1 foraminal, and L5-S1 transforaminal) before receiving adhesiolysis and neuroplasty. All patients underwent nerve conduction studies and magnetic resonance imaging (MRI). Pain severity levels were assessed and measured using the Oswestry Disability Questionnaire (OSW) and the Visual Analog Scale (VAS). Patient satisfaction was evaluated using a Likert scale. The first assessment was performed prior to the procedure to determine the patients' baseline levels of pain severity. Follow-up assessments were performed 1-, 3-, and 6-months after the procedure. RESULTS: Results of the group pairwise analysis indicated that, relative to baseline, there were significant decreases in pain relief scores (VAS and OWS) and functional assessment expressed by patients' satisfaction across all time intervals and in all 3 groups (P < 0.01). Conversely, a between group analysis revealed that VAS, OWS, and patient satisfaction scores were comparable across the 3 groups at all time intervals (P > 0.05). There were no differences in rates of complications between the 3 different groups. LIMITATIONS: Our study was limited by the low number of patients and the short duration (6 months) of follow up. CONCLUSION: The 3 anatomical approaches (caudal, S1 foraminal, and L5-S1 transforaminal) result in the same outcome with regard to pain relief and complication rate.

PMID- 30282399 TI - Enhanced Pain Sensitivity with Systemic Ultrastructural Changes of the Nervous Systems after Cobra Venom Injection is Reversed by Electroacupuncture Treatment. AB - BACKGROUND: Electroacupuncture (EA) has been proved to be effective in treating certain neuropathic pain conditions. The mechanisms of pain relief by EA are not fully understood. There have been sporadic reports of damage in the peripheral nervous system (PNS) and regions of the central nervous system (CNS) at the ultrastructural level following peripheral nerve injury. However, information about possible systemic changes in the PNS and CNS after nerve injury is scarce. OBJECTIVES: The goal of this study was to examine the ultrastructural changes of the nervous system induced by a local injection of cobra venom into the sciatic nerve and to compare the ultrastructural changes in rats with or without treatment with EA or pregabalin. STUDY DESIGN: An experimental study. SETTING: Department of Anesthesiology, Pain Medicine, and Critical Care Medicine, Aviation General Hospital of China Medical University. METHODS: In this study, using an established model of sciatic neuralgia induced by local injection of cobra venom into the sciatic nerve, we examined ultrastructural changes of the PNS and CNS and how they respond to EA and pregabalin treatment. EA and pregabalin were given daily from postoperative day (POD) 14 to 36. Based on previous works, the frequency of EA stimulation of the ST36 and GB34 acupoints was held to 2/100 Hz variable. Pain sensitivity in the sciatic neuralgia rats with and without treatments was assessed using the von Frey test. Ultrastructural alterations were examined bilaterally in the prefrontal cortex, hippocampus, medulla oblongata; and the cervical, thoracic, and lumbar spinal cords on PODs 14, 40, and 60. Ultrastructural examinations were also carried out on the bilateral sciatic nerves and dorsal root ganglion (DRG) at the cervical, thoracic and lumbar levels. In rats treated with EA or pregabalin, the ultrastructure was examined on PODs 40 and 60. RESULTS: Behavioral signs of pain and systemic ultrastructural changes including demyelination were observed at all levels of the PNS and CNS in rats with sciatic neuralgia. After intervention, the mechanical withdrawal thresholds of the EA group and pregabalin group were significantly higher than that of the cobra venom group (P < 0.05). Both EA and pregabalin treatments partially reversed increased cutaneous sensitivity to mechanical stimulation. However, only the EA treatment was able to repair the ultrastructural damages caused by cobra venom. LIMITATIONS: The results confirm that peripheral nerve injury led to the ultrastructural damage at different levels of the CNS as demonstrated with electron microscopy; however, we need to further verify this at both the molecular level and in light microscope level. Sciatic neuralgia induced by cobra venom is a chemical injury, and whether this exactly mimics a peripheral nerve mechanical injury is still unclear. CONCLUSIONS: Local cobra venom injection leads to systemic neurotoxicity. EA and pregabalin alleviate pain via different mechanisms.

PMID- 30282400 TI - Ionizing Radiation Dose Exposure to the Ocular Region of Pain Physicians During C arm Guided Pain Interventions. AB - BACKGROUND: The growth of interventional pain medicine in recent years has resulted in more procedures being carried out under fluoroscopic guidance. The proximity of the pain physician (PP) to ionization radiation (IR) potentially increases the risk of radiation exposure to the ocular region. A European directive has reduced the limits of occupational ocular dose 7.5-fold. OBJECTIVES: The objectives of this study are to quantify the typical IR exposure in the ocular region of PP and to compare it to recommended international guidelines. STUDY DESIGN: Three consultants involved in the pain unit service were enrolled in the study to reflect the dose implications involved with different caseloads, training obligations, and procedure types. All 3 consultants were experienced primary operators. SETTING: The study was undertaken at the pain management suite in the South Infirmary Victoria University Hospital (SIVUH). Annually, this unit performs 2,800 fluoroscopic guide pain procedures. METHODS: Thermoluminescent dosimeters (TLDs) calibrated to measure eye lens doses [Hp (0.07)] and whole-body doses (WBDs) were fitted to 3 pain consultants while they undertook imaging-guided pain procedures using mobile C-arm fluoroscopy over a 3 month period. The duration of radiation exposure, screening time (seconds), and procedure type were recorded. Radiation dose was calculated to estimate the effective radiation dose to the ocular region using (i) dose-area product (DAP) in milliGray per centimeter squared (mGycm2) and (ii) Air Kerma (AK) values in mGy. RESULTS: IR doses were effectively recorded in 682 cases over 3 months and the data extrapolated. The estimated annual lens dose experienced by pain physicians performing fluoroscopy-guided procedures is less than the recommended international guidelines. A significant linear relationship between screening time and IR exposure was estimated (rs = 0.93, P < 0.01). LIMITATIONS: In many centers, including our own, fluoroscopy procedures are undertaken by nonconsultant staff. Therefore, a small single-center cohort recruiting experienced consultant staff and not including pain fellows or registrars/residents with varying levels of experience is a limitation. CONCLUSION: While IR to the ocular region was significantly less than the recommended European safety guidelines, the annual dose needs to be confirmed in pain physicians with a lesser degree of clinical experience.

PMID- 30282401 TI - Patients' Perceptions of Chronic Pain During the Economic Crisis: Lessons Learned from Greece. AB - BACKGROUND: Chronic pain is well known to be influenced by various social factors; however, the impact of financial issues on pain has not been extensively studied. OBJECTIVE: The aim of this study was to investigate the impact of the economic crisis on pain and quality of life in Greek patients suffering from chronic pain. STUDY DESIGN: The study employed a prospective, open-label design. SETTING: The study setting was the Pain Unit of Attikon University Hospital in Athens, Greece. METHODS: The study surveyed 200 randomly selected outpatients with chronic pain during two different time periods (2012 and 2016). Patients completed a structured questionnaire to assess the impact of the economic crisis on multiple aspects of pain and pain management, health care, and quality of life. Personality characteristics and stress were also evaluated using the DASS 42 and the LOT-R questionnaires. RESULTS: Most patients in both periods believed that the economic crisis led to a worsening of their symptoms (75%) and quality of life (97%). Most patients (97.5%) also believed that the intensity of their pain would have been improved if their financial status had been better. Their main concerns about the future were "the possibility of not having access to health care facilities and medication" (94.5%), "stress" (43%), and "fear of financial strain" (30.5%). Higher levels of anxiety, stress, and pessimism were associated with higher levels of pain and lower quality of life. LIMITATIONS: The study is based on a small sample size. CONCLUSIONS: This study identified impacts of the financial crisis on chronic pain and quality of life, pointing to the need for measures to solve this problem. KEY WORDS: Pain, global financial crisis, quality of life, quality of health care, psychosocial factors. PMID- 30282402 TI - Combination of Pulsed Radiofrequency with Continuous Radiofrequency Thermocoagulation at Low Temperature Improves Efficacy and Safety in V2/V3 Primary Trigeminal Neuralgia. AB - BACKGROUND: Primary trigeminal neuralgia (TN) is a common clinical refractory neuralgia. Severe pain is experienced during episodes, severely impacting the patient's quality of life. Long-term suffering from the disease can lead to anxiety, depression, and even suicide. The pathological processes involved in TN are complex, the mechanisms of pathogenesis are unknown, and effective treatment is lacking. OBJECTIVE: This study aimed to assess the efficacy and safety of computed tomography (CT)-guided pulsed radiofrequency (PRF) combined with low temperature continuous radiofrequency (CRF) thermocoagulation in V2/V3 primary trigeminal neuralgia. STUDY DESIGN: This research used a retrospective comparative study design. SETTING: The research took place at Shengjing Hospital of China Medical University. METHODS: A total of 80 hospitalized patients with TN were selected between January 2014 and December 2015 and randomly assigned to 2 groups differentiated by therapeutic method: CRF (CRF group, n = 40) and PRF + CRF (PCRF group, n = 40). Radiofrequency therapy was performed under the guidance of CT. Follow-up measures assessed preoperative conditions, pain remission, complications and side effects, recovery time, and recurrence rate over the 2 years following the surgery. RESULTS: The Visual Analog Scale (VAS) scores decreased in both groups after surgery. After one month, the decrease in the VAS score in the PCRF group was more apparent, and this difference was maintained for 2 years. The total efficiency rates in the CRF and PCRF groups were 85% and 97.5%, respectively, at 6 months, 1 year, and 2 years post-surgery. The differences in total efficiency rate of pain between the 2 groups at 6 months, 1 year, and 2 years were statistically significant. Recovery times in the PCRF group were shorter than those in the CRF group. Specifically, recovery times for facial numbness in the CRF and PCRF groups were 3.12 +/- 1.21 months and 2.23 +/- 1.02 months, respectively. Recovery times for masticatory muscle weakness were 4.33 +/- 1.54 months and 3.42 +/- 0.98 months, respectively. LIMITATIONS: This study is limited by being a retrospective study, and by having a relatively small sample size from a single center. CONCLUSIONS: CT-guided PRF combined with low temperature CRF thermocoagulation for treating V2/V3 primary TN effectively relieves pain, increases late-stage pain remission rate, reduces complications, and reduces the rate of recurrence.

PMID- 30282403 TI - Contribution of Spinal PKCgamma Expression to Short- and Long-lasting Pain Behaviors in Formalin-induced Inflamed Mice. AB - BACKGROUND: Over-expression of spinal protein kinase Cgamma(PKCgamma) contributes to the induction of persistent bilateral hyperalgesia following inflammatory injury, yet the role of spinal PKCgamma in short- and long-lasting pain behavior is poorly understood. OBJECTIVE: This study aimed to characterize the contribution of spinal PKCgamma to spontaneous pain and long-lasting bilateral hyperalgesia in formalin-induced inflamed mice using pharmacological inhibition. STUDY DESIGN: Laboratory animal study. SETTING: The study was performed in the Department of Human Anatomy and K.K. Leung Brain Research Centre, Preclinical School of Medicine, the Fourth Military Medical University (Xi'an, China) and the Department of Anesthesiology, Fuzhou General Hospital (Fuzhou, China). METHODS: Male mice were unilaterally intraplantarly injected with formalin to induce inflammatory pain. Spontaneous pain behaviors, including flinches and lickings, were recorded by off-line video during the first hour post-injection and counted. Using von Frey tests, long-lasting bilateral mechanical paw withdrawal thresholds were determined before injection and at indicated time points thereafter. Temporal expression of spinal PKCgamma was observed by immunohistochemical staining. For pharmacological inhibition, mice were treated daily with intrathecal Tat carrier or selective PKCgamma inhibitor KIG31-1, from 1 hour prior to 10 days after formalin injection. Spontaneous pain behaviors and long lasting bilateral mechanical hyperalgesia were assessed. Spinal PKCgamma expression was also observed by using immunohistochemical staining and western blot. RESULTS: The number of PKCgamma-immunoreactive (ir) spinal neurons was significantly higher at 10 days, but not 2 hours, after formalin intraplantar injection, and accompanied by long-lasting bilateral hyperalgesia. Furthermore, long-lasting bilateral hyperalgesia could be reversed by pharmacological inhibition of over-expressed spinal PKCgamma; however, pretreating with intrathecal KIG31-1 showed no antinociceptive effects on short-term spontaneous pain behaviors. LIMITATIONS: All results were obtained from the mice and no PKCgamma inhibitors were available through clinical practice. Therefore, it remains difficult to draw definitive connections between animal research and human application. CONCLUSION: Our findings suggest that spinal PKCgamma plays a predominant role in long-lasting bilateral hyperalgesia, but not in the spontaneous pain behaviors induced by formalin. KEY WORDS: Formalin, spontaneous pain, mechanical hyperalgesia, protein kinase C gamma, KIG31-1, mice. PMID- 30282404 TI - Feasibility of Percutaneous Robot-Assisted Epiduroscopic System. AB - BACKGROUND: Endoscopy has replaced open surgery, especially in spinal surgery. Among them, image-guided epiduroscopy allows pain generators to be identified, including epidural adhesion, fibrotic tissues, root compression, and spinal stenosis. However, the heavy lead apron worn by pain physicians to avoid exposure to radiation can induce occupational hazards, such as orthopedic complications and radiation-induced cancer. Hence, we developed a robotic system to address these problems. OBJECTIVE: The aim of the study was to evaluate the feasibility of a robot-controlled epiduroscopic system. STUDY DESIGN: In vivo animal experiment. SETTING: University in Republic of Korea. METHODS: The robot controlled epiduroscopic system was developed using the open architecture robot system (The Raven Surgical Robotic System, CITRIS, Berkley, CA, USA). The robotic system consists of a lab-made epiduroscope, steering section, robotic arm, and manipulator. For the in vivo study, 2 Yorkshire pigs were used to simulate an epiduroscopic procedure with the robotic system. RESULTS: The insertion and steering of the catheter was performed safely, and epiduroscopic visualization was obtained without side effects. There were no device-related complications. Radiation exposure for the primary operator was 80% lower than the levels found during conventional epiduroscopic procedures. All live pigs showed normal behavior without any signs of pain. The mean time to reach the target region was less than 8 minutes. LIMITATIONS: The epiduroscopic procedure was performed on pigs and not on humans. The dimensions of the spinal canal of pigs cannot compare to those of humans. CONCLUSIONS: We demonstrated the feasibility of the robot assisted epiduroscopic system. KEY WORDS: Epiduroscopy, robotic system, spine, pig, animal model. PMID- 30282405 TI - Mexiletine Usage in a Chronic Pain Clinic: Indications, Tolerability, and Side Effects. AB - BACKGROUND: Intravenous lidocaine has multiple applications in the management of acute and chronic pain. Mexiletine, an oral lidocaine analogue, has been used in a number of chronic pain conditions although its use is not well characterized. OBJECTIVES: To report our experience using mexiletine in a chronic pain population, specifically looking at tolerability, side effects, and EKG changes. STUDY DESIGN: Retrospective, cohort study. SETTING: Three chronic pain clinics within a hospital system in Detroit, MI. METHODS: All patients who had a mexiletine prescription between August 2015 and August 2016 were queried via the electronic medical record. Each chart was examined for demographics, QTc changes on EKG, length of use, and reasons for stoppage. RESULTS: There were 74 total patients identified in the chronic pain management clinics as receiving at least 1 mexiletine prescription over the 1-year time period. Twice as many women as men received mexiletine prescriptions. Neuropathic pain was the most common primary diagnosis (64%) which included diabetic neuropathy, radiculopathy, and others. Fibromyalgia was the next most common primary diagnosis (28%). A QTc change on the EKG showed a mean decrease of 0.1 ms and median increase of 1.5 ms. At 6 months (180 days), approximately 30% of the patients remained on mexiletine therapy, and 28% remained on the therapy at 1 year (360 days). Median duration of use was 60 days and the mean was 288 days. Neurologic and gastrointestinal side effects were the most commons reason for stoppage. All side effects were mild and resolved with stoppage. After side effects, lack of response, or loss of efficacy, were the next most common reasons for stoppage. LIMITATIONS: Pain relief and outcomes were not specifically examined due to confounding factors including interventional treatments and multiple treatment modalities. This was a retrospective, cohort study limited to our specific clinic population with a relatively high loss to follow-up rate. CONCLUSION: Mexiletine is rarely a first line option for chronic pain management and is often used when multiple other modalities have failed. By reporting our experience, we hope other clinicians may have more familiarity with the drug's use in a chronic pain practice. It appears reasonably tolerable, may not require frequent EKG monitoring, and can be an appropriate adjunct in the chronic pain population. More research is needed regarding efficacy and dose titration for mexiletine in chronic pain.

AB - Increased emphasis on competency-based learning modules and widespread departure from traditional models of Halstedian apprenticeship have made surgical simulation an increasingly appealing component of medical education. Surgical simulators are available in numerous modalities, including virtual, synthetic, animal, and non-living models. The ideal surgical simulator would facilitate the acquisition and refinement of surgical skills prior to clinical application, by mimicking the size, color, texture, recoil, and environment of the operating room. Simulation training has proven helpful for advancing specific surgical skills and techniques, aiding in early and late resident learning curves. In this review, the current applications and potential benefits of incorporating simulation-based surgical training into residency curriculum are explored in depth, specifically in the context of plastic surgery. Despite the prevalence of simulation-based training models, there is a paucity of research on integration into resident programs. Current curriculums emphasize the ability to identify anatomical landmarks and procedural steps through virtual simulation. Although transfer of these skills to the operating room is promising, careful attention must be paid to mastery versus memorization. In the authors' opinions, curriculums should involve step-wise employment of diverse models in different stages of training to assess milestones. To date, the simulation of tactile experience that is reminiscent of real-time clinical scenarios remains challenging, and a sophisticated model has yet to be established. PMID- 30282411 TI - Accessory auricle: Classification according to location, protrusion pattern and body shape. AB - BACKGROUND: Accessory auricles (AAs) are common congenital anomalies. We present a new classification according to location and shape, and propose a system for coding the classifications. METHODS: This study was conducted by reviewing the records of 502 patients who underwent surgery for AA. AAs were classified into three anatomical types: intraauricular, preauricular, and buccal. Intraauricular AAs were divided into three subtypes: intracrural, intratragal, and intralobal. Preauricular AAs were divided into five subtypes: precrural, superior pretragal, middle pretragal, inferior pretragal, and prelobal. Buccal AAs were divided into two subtypes: anterior buccal and posterior buccal. AAs were also classified according to their protrusion pattern above the surrounding surface: pedunculated, sessile, areolar, remnant, and depressed. Pedunculated and sessile AAs were subclassified as spherical, ovoid, lobed, and nodular, according to their body shape. Cartilage root presence and family history of AA were reviewed. A coding system for these classifications was also proposed. RESULTS: The total number of AAs in the 502 patients was 1,003. Among the locations, the superior pretragal subtype (27.6%) was the most common. Among the protrusion patterns and shapes, pedunculated ovoid AAs were the most common in the preauricular (27.8%) and buccal areas (28.0%), and sessile lobed AAs were the most common in the intraauricular area (48.7%). The proportion of AAs with a cartilage root was 78.4%, and 11% of patients had a family history. The most common type of preauricular AA was the superior pretragal pedunculated ovoid AA (13.2%) with a cartilage root. CONCLUSIONS: This new system will serve as a guideline for classifying and coding AAs. PMID- 30282410 TI - Development of an easy-to-handle murine model for the characterization of radiation-induced gross and molecular changes in skin. AB - BACKGROUND: Radiation-induced skin injury is a dose-limiting complication of radiotherapy. To investigate this problem and to develop a framework for making decisions on treatment and dose prescription, a murine model of radiation-induced skin injury was developed. METHODS: The dorsal skin of the mice was isolated, and irradiation was applied at single doses of 15, 30, and 50 Gy. The mice were followed for 12 weeks with serial photography and laser Doppler analysis. Sequential skin biopsy samples were obtained and subjected to a histological analysis, immunostaining against transforming growth factor beta (TGF-beta), and Western blotting with Wnt-3 and beta-catenin. Increases in the levels of TGF beta, Wnt, and beta-catenin were detected after irradiation. RESULTS: All tested radiation doses caused progressive dermal thickening and fibrosis. The cause of this process, however, may not be radiation alone, as the natural course of wound healing may elicit a similar response. The latent appearance of molecular and histological markers that induce fibrosis in the 15 Gy group without causing apparent gross skin injuries indicates that 15 Gy is an appropriate dose for characterizing the effects of chronic irradiation alone. Thus, this model best mimics the patterns of injury that occur in human subjects. CONCLUSIONS: This animal model can be used to elucidate the gross and molecular changes that occur in radiation-induced skin injury and provides an effective platform for studying this adverse effect without complicating the process of wound healing. PMID- 30282412 TI - National perioperative outcomes of flap coverage for pressure ulcers from 2005 to 2015 using American College of Surgeons National Surgical Quality Improvement Program. AB - BACKGROUND: Complication rates after flap coverage for pressure ulcers have been high historically. These patients have multiple risk factors associated with poor wound healing and complications including marginal nutritional status, prolonged immobilization, and a high comorbidities index. This study utilizes the National Surgical Quality Improvement Program (NSQIP) to examine perioperative outcomes of flap coverage for pressure ulcers. METHODS: Data from the NSQIP database (2005 2015) for patient undergoing flap coverage for pressure ulcers was identified. Demographic, perioperative information, and complications were reviewed. One-way analysis of variance and Pearson chi-square were used to assess differences for continuous variables and nominal variables, respectively. Multivariate logistic regression was performed to identify independent risk factors for complications. RESULTS: There were 755 cases identified: 365 (48.3%) sacral ulcers, 321 (42.5%) ischial ulcers, and 69 (9.1%) trochanteric ulcers. Most patients were older male, with some degree of dependency, neurosensory impairment, high functional comorbidities score, and American Society of Anesthesiologists class 3 or above. The sacral ulcer group had the highest incidence of septic shock and bleeding, while the trochanteric ulcer group had the highest incidence of superficial surgical site infection. There was an overall complication rate of 25% at 30-day followup. There was no statistical difference in overall complication among groups. Total operating time, diabetes, and non-elective case were independent risk factors for overall complications. CONCLUSIONS: Despite patients with poor baseline functional status, flap coverage for pressure ulcer patients is safe with acceptable postoperative complications. This type of treatment should be considered for properly selected patients. PMID- 30282413 TI - Location of the umbilicus in Korean women and its changes after breast reconstruction with an ipsilateral pedicled rectus abdominis musculocutaneous flap. AB - BACKGROUND: The umbilicus makes an important contribution to the natural appearance of the abdomen. To date, studies on its position in Korean women are lacking, and no standards have been established. The purpose of this study was to investigate the position of umbilicus in Korean women and to review changes in its position after ipsilateral pedicled rectus abdominis musculocutaneous (IP RAM) flap. METHODS: This research consisted of two studies. In first study, 100 females who visited the emergency department with gastroenteritis between 2007 and 2011 were included. In second study, 40 women who underwent IP-RAM flap in the same period were included. Using abdominal computed tomography, we measured the distance between xiphoid process and umbilicus, represented by value a, and the distance between umbilicus and symphysis pubis, represented by value b. Thus, the location of the umbilicus was represented by the ratio a/b. The data were analyzed using Pearson correlation test and paired t-test. RESULTS: In study 1, the mean value of a/b was 1.07. Pearson correlation test revealed a significant correlation between age and a/b. In study 2, the mean value of a/b was 1.16 in preoperative measurements and 1.01 in postoperative measurements. The paired t test showed a significant difference between preoperative and postoperative measurements, indicating cephalic migration of the umbilicus after surgery. CONCLUSIONS: The natural position of the umbilicus showed caudal migration with aging. Additionally, in a comparison of preoperative and postoperative measurements in patients who underwent IP-RAM flap, cephalic migration of the umbilicus was observed after surgery. PMID- 30282414 TI - Impact of hormonal therapy and other adjuvant therapies on contralateral breast volume change after implant-based breast reconstruction. AB - BACKGROUND: Adjuvant therapy after breast surgery, including tamoxifen or aromatase inhibitors, improves the postoperative outcomes and long-term survival of breast cancer patients. The aim of this study was to determine whether volume changes occurred in the contralateral breast during hormonal or other adjuvant therapies. METHODS: This study reviewed 90 patients who underwent unilateral breast reconstruction between September 2012 and April 2018 using tissue expanders and a permanent implant after the surgical removal of breast cancer. The volume of the contralateral breast was measured using a cast before the first (tissue expander insertion) and second (permanent implant change) stages of surgery. Changes in breast volume were evaluated to determine whether adjuvant therapy such as hormonal therapy, chemotherapy, and radiation therapy influenced the volume of the contralateral breast. RESULTS: The group receiving tamoxifen therapy demonstrated a significant decrease in volume compared with the group without tamoxifen (-7.8% vs. 1.0%; P=0.028). The aromatase inhibitor-treated group showed a significant increase in volume compared with those who did not receive therapy (-6.2% vs. 4.5%; P=0.023). There were no significant differences between groups treated with other hormonal therapy, chemotherapy, or radiation therapy. CONCLUSIONS: Patients who received tamoxifen therapy showed a significant decrease in volume in the contralateral breast, while no significant change in weight or body mass index was found. Our findings suggest that we should choose smaller implants for premenopausal patients, who have a high likelihood of receiving tamoxifen therapy. PMID- 30282415 TI - Breast reconstruction statistics in Korea from the Big Data Hub of the Health Insurance Review and Assessment Service. AB - BACKGROUND: Previously, surveys have been used to investigate breast reconstruction statistics. Since 2015, breast reconstruction surgery after mastectomy has been covered by the National Health Insurance Service in Korea, and data from breast reconstruction patients are now available from the Health Insurance Review and Assessment Service (HIRA). We investigated statistics in breast reconstruction in Korea through statistics provided by the HIRA Big Data Hub. METHODS: We investigated the number of cases in mastectomy and breast reconstruction methods from April 1, 2015 to December 31, 2016. Data were furnished by the HIRA Big Data Hub and accessed remotely online. Results were tabulated using SAS Enterprise version 6.1. RESULTS: The 31,155 mastectomy cases included 7,088 breast reconstruction cases. Implantbased methods were used in 4,702 cases, and autologous methods in 2,386. The implantbased reconstructions included 1,896 direct-to-implant and 2,806 tissue-expander (2-stage) breast reconstructions. The 2-stage tissue-expander reconstructions included 1,624 expander insertions (first stage) and 1,182 expander-to-permanent-implant exchanges (second stage). Of the autologous breast reconstructions, 705 involved latissimus dorsi muscle flaps, 498 involved pedicled transverse rectus abdominis myocutaneous (TRAM) flaps, and 1,183 involved free-tissue transfer TRAM flaps, including deep inferior epigastric perforator free-tissue transfer flaps. There were 1,707 nipple-areolar complex reconstructions, including 1,565 nipple reconstructions and 142 areola reconstructions. The 1-year mean number of breast reconstructions was 4,050. CONCLUSIONS: This was the first attempt to evaluate the total number of breast reconstruction procedures using accurate, comprehensive data, and our findings may prove valuable as a foundation for future statistical studies of breast reconstruction procedures in Korea. PMID- 30282416 TI - Incorporating a continuous suction system as a preventive measure against fistula related complications in head and neck reconstructive surgery. AB - BACKGROUND: Although previous studies have focused on determining prognostic and causative variables associated with fistula-related complications after head and neck reconstructive surgery, only a few studies have addressed preventive measures. Noting that pooled saliva complicates wound healing and precipitates fistula-related complications, we devised a continuous suction system to remove saliva during early postoperative recovery. METHODS: A continuous suction system was implemented in 20 patients after head and neck reconstructive surgery between January 2012 and October 2017. This group was compared to a control group of 16 patients at the same institution. The system was placed orally when the lesion was on the anterior side of the retromolar trigone area, and when glossectomy or resection of the mouth floor was performed. When the orohypopharynx and/or larynx were eradicated, the irrigation system was placed in the pharyngeal area. RESULTS: The mean follow-up period was 9.2+/-2.4 months. The Hemovac system was applied for an average of 7.5 days. On average, 6.5 days were needed for the net drain output to fall below 10 mL. Complications were analyzed according to their causes and rates. A fistula occurred in two cases in the suction group. Compared to the control group, a significant difference was noted in the surgical site infection rate (P<0.031). CONCLUSIONS: Clinical observations showed reduced saliva pooling and a reduction in the infection rate. This resulted in improved wound healing through the application of a continuous suction system. PMID- 30282417 TI - Volar plate avulsion fracture alone or concomitant with collateral ligament rupture of the proximal interphalangeal joint: A comparison of surgical outcomes. AB - BACKGROUND: Volar plate avulsion fracture of the proximal interphalangeal (PIP) joint is one of the most common hand injuries. In this study, we divided patients into two groups: patients with pure volar plate avulsion fracture, and patients with volar plate avulsion fracture concomitant with collateral ligament rupture. The purpose of this study was to compare long-term surgical outcomes between the two groups. As a secondary measure, the Mitek bone anchoring and polydioxanone (PDS) bone suturing techniques were compared. METHODS: A single-institutional retrospective review of the surgical treatment of volar plate avulsion fracture was performed. The cases were divided into those with pure volar plate avulsion fracture (group A, n=15) and those with volar plate avulsion fracture concomitant with collateral ligament rupture (group B, n=15). Both groups underwent volar plate reattachment using Mitek bone anchoring or PDS bone suturing followed by 2 weeks of immobilization in a dorsal protective splint. RESULTS: The average range of motion of the PIP joint and extension lag were significantly more favorable in group A (P<0.05). Differences in age; follow-up period; flexion function; visual analog scale scores; disabilities of the arm, shoulder, and hand scores; and the grip strength ratio between the two groups were non-significant. No significant differences were found in the surgical outcomes of Mitek bone anchoring and PDS bone suturing in group A. CONCLUSIONS: Overall, the surgical outcomes of volar plate reattachment were successful irrespective of whether the collateral ligaments were torn. However, greater extension lag was observed in cases of collateral ligament injury. PMID- 30282418 TI - Use of a helical composite free flap for alar defect reconstruction with a supermicrosurgical technique. AB - The highly contoured nature of the nose and the abundant free margin makes it especially difficult to reconstruct. In this report, we describe the use of a new helical rim free flap technique for the reconstruction of full-thickness nasal alar defects via supermicrosurgery. Briefly, after a wide excision with a margin of 0.7 cm, an alar defect with a size of 1*1*0.5cm was obtained, which included the full thickness of the skin, mucosa, and lower lateral cartilage. Vessel dissection was performed in a straightforward manner, starting from the incision margin for flap harvest, without any further dissection for reach the greater trunk of the superficial temporal artery. The flap was inset in order to match the contour of the contralateral ala. We closed the donor site via rotation and advancement. No donor site morbidity was observed, despite the presence of a small scar that could easily be covered with hair. The alar contour was satisfactory, and the patient was satisfied with the results. The supermicrosurgical technique did not require further dissection to identify the vessels for anastomosis, leading to better cosmetic outcomes and a reduced operating time. PMID- 30282419 TI - Mechanical irritation by protruding bone: A possible cause of breast implant rupture. AB - Although breast implants have been in clinical use for almost 6 decades and have undergone considerable development during this time, implant rupture is still a dreaded long-term complication. Some obvious external factors, such as trauma, can lead to implant rupture, but many studies have reported a high rate of "spontaneous" implant rupture. Herein, we present two cases with the aim of raising awareness of a new possible cause of "spontaneous" implant rupture: mechanical irritation by bony protrusions. PMID- 30282420 TI - Recurrent carpal tunnel syndrome associated with extension of flexor digitorum muscle bellies into the carpal tunnel: A case series. AB - While the success or failure of carpal tunnel release ultimately depends on the interplay of a wide array of factors, a broad understanding of the normal anatomy of the carpal tunnel accompanied by awareness of the possible variations of the individual structures that make up its contents is crucial to optimizing surgical outcomes. While anatomic variants such as extension of the flexor digitorum muscle bellies have been described as a cause of primary carpal tunnel syndrome (CTS), there have been no reports depicting its association with recurrent CTS following initially successful carpal tunnel release, a finding with potentially significant prognostic implications that can aid in operative planning. In such cases where muscle extension is identified preoperatively, careful debulking of the muscle belly may be beneficial in improving long-term surgical outcomes. PMID- 30282421 TI - Simultaneous reconstruction of the forearm extensor compartment tendon, soft tissue, and skin. AB - Malignant peripheral nerve sheath tumor (MPNST) is a very rare type of sarcoma, with an incidence of 0.001%. MPNST has a 5-year survival rate near 80%, so successful reconstruction techniques are important to ensure the patient's quality of life. Sarcoma of the forearm is known for its poor prognosis, which leads to wider excision, making reconstruction even more challenging due to the unique anatomical structure and delicate function of the forearm. A 44-year-old male presented with a large mass that had two aspects, measuring 9*6 cm and 7*5 cm, on the dorsal aspect of the right forearm. The extensor compartment muscles (EDM, EDC, EIP, EPB, EPL, ECRB, ECRL, APL) and invaded radius were resected with the mass. Tendon transfer of the entire extensor compartment with skin defect coverage using a 24*8 cm anterolateral thigh (ALT) perforator free flap was performed. The patient was discharged after 18 days without wound complications, and has not complained of discomfort during supination, pronation, or wrist extension/flexion through 3 years of follow-up. To our knowledge, this is the first report of successful reconstruction of the entire forearm extensor compartment with ALT free flap coverage after resection of MPNST. PMID- 30282422 TI - A novel technique for large and ptotic breast reconstruction using a latissimus dorsi myocutaneous flap set at the posterior aspect, combined with a silicone implant, following tissue expander surgery. AB - Large and ptotic breast reconstruction in patients who are not candidates for a transverse rectus abdominalis myocutaneous flap and revision surgery for the contralateral breast remains challenging. We developed a novel breast reconstruction technique using a latissimus dorsi myocutaneous (LD m-c) flap set at the posterior aspect of the reconstructed breast, combined with an anatomical silicone breast implant (SBI), following tissue expander surgery. We performed the proposed technique in four patients, in whom the weight of the resected tissue during mastectomy was >500 g and the depth of the inframammary fold (IMF) was >3 cm. After over-expansion of the lower portion of the skin envelope by a tissue expander, the LD m-c flap was transferred to cover the lower portion of the breast defect and to achieve a ptotic contour, with the skin paddle set at the posterior aspect of the reconstructed breast. An SBI was then placed in the rest of the breast defect after setting the LD m-c flap. No major complications were observed during the follow-up period. The proposed technique resulted in symmetrical and aesthetically satisfactory breasts with deep IMFs, which allowed proper fitting of the brassiere, following large and ptotic breast reconstruction.

AB - Velopharyngeal insufficiency (VPI) is a common complication after primary palatoplasty. Although the several surgical treatments of VPI have been introduced, there is no consensus guide to select the optimal surgical treatment for VPI patients. The selection of surgical treatment for VPI depends on a multimodal patient evaluation, such as perceptual speech evaluation, nasometery and nasoendoscopy. We can provide more adequate treatment for VPI through the deeper understanding of anatomy and physiology in VPI. PMID- 30282425 TI - Safety, efficacy, and onset of a novel botulinum toxin type A (Nabota) for the treatment of glabellar frown lines: a single-arm, prospective, phase 4 clinical study. AB - BACKGROUND: Safety, efficacy, and time to onset of effect of botulinum toxin type A is of importance to persons who seek improvement in glabellar frown lines, but this has not been well studied. The aim of this study was to determine the safety, efficacy, and onset of action of a newly developed botulinum toxin type A (Nabota) for the treatment of glabellar frown lines. METHODS: This was a single arm, open-label, and phase 4 clinical study. Forty-two subjects with glabellar lines were treated with five times of intramuscular injection of 0.1 mL (4 U/0.1 mL) for a total of 20 U of Nabota. Efficacy and safety were assessed at 2, 3, 4, 5, and 14 days. Efficacy was assessed by the investigator and it was defined as a 1-point change on a 4-point scale. RESULTS: Improvement in glabellar frown lines at maximum frown was observed in 85.4% of subjects 2 days after administration. Improvement in glabellar lines at rest was observed in 51.2% of subjects 2 days after administration, and the proportion of subjects showing improvement increased with time. No severe adverse events were recorded. CONCLUSION: Onset of action was observed in the majority of subjects by 2 days after administration of Nabota. In addition, Nabota was found to be safe and effective for the treatment of glabellar frown lines. PMID- 30282426 TI - Use of resorbable mesh and fibrin glue for restoration in comminuted fracture of anterior maxillary wall. AB - BACKGROUND: The facial bone has a complex structure compared to other bones, and various types of fractures can occur due to its characteristics. Among them, in comminuted fractures of anterior maxillary wall, multiple depressed and impacted bony segments cannot be reduced easily when performing internal fixation using plates and screws or wires, and inadequate restoration leads to a range of complications. This paper introduces an alternative technique using a resorbable mesh with fibrin glue to restore comminuted fractures of anterior maxillary wall. METHODS: Thirteen patients were diagnosed with comminuted fractures of anterior maxillary wall between March 2017 and February 2018 in the authors' hospital. All patients with comminuted fractures of anterior maxillary wall underwent restoration using resorbable mesh with fibrin glue. The patients' demographics, causes of facial trauma, mean operation time, length of hospital stay, follow-up period, and complications were recorded. RESULTS: No major complications and only one hypoesthesia of the skin area was noted. Three months after surgery, the hypoesthesia recovered completely. After surgery (mean, 3.9 months; range, 2-12 months), computed tomography showed that the bone fragments in all patients were fixed successfully in their anatomical places. CONCLUSION: In comminuted fractures of anterior maxillary wall, the use of a resorbable mesh with fibrin glue can be an advantageous and effective method for a successful restoration without complications. PMID- 30282427 TI - Effects of three-dimensionally printed polycaprolactone/beta-tricalcium phosphate scaffold on osteogenic differentiation of adipose tissue- and bone marrow-derived stem cells. AB - BACKGROUND: Autogenous bone grafts have several limitations including donor-site problems and insufficient bone volume. To address these limitations, research on bone regeneration is being conducted actively. In this study, we investigate the effects of a three-dimensionally (3D) printed polycaprolactone (PCL)/tricalcium phosphate (TCP) scaffold on the osteogenic differentiation potential of adipose tissue-derived stem cells (ADSCs) and bone marrow-derived stem cells (BMSCs). METHODS: We investigated the extent of osteogenic differentiation on the first and tenth day and fourth week after cell culture. Cytotoxicity of the 3D printed PCL/beta-TCP scaffold was evaluated by 3-(4,5-dimethylthiazol-2-yl)-5-(3 carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium assay, prior to osteogenic differentiation analysis. ADSCs and BMSCs were divided into three groups: C, only cultured cells; M, cells cultured in the 3D printed PCL/beta-TCP scaffold; D, cells cultured in the 3D printed PCL/beta-TCP scaffold with a bone differentiation medium. Alkaline phosphatase (ALP) activity assay, von Kossa staining, reverse transcription-polymerase chain reaction (RT-PCR), and Western blotting were performed for comparative analysis. RESULTS: ALP assay and von Kossa staining revealed that group M had higher levels of osteogenic differentiation compared to group C. RT-PCR showed that gene expression was higher in group M than in group C, indicating that, compared to group C, osteogenic differentiation was more extensive in group M. Expression levels of proteins involved in ossification were higher in group M, as per the Western blotting results. CONCLUSION: Osteogenic differentiation was increased in mesenchymal stromal cells (MSCs) cultured in the 3D printed PCL/TCP scaffold compared to the control group. Osteogenic differentiation activity of MSCs cultured in the 3D printed PCL/TCP scaffold was lower than that of cells cultured on the scaffold in bone differentiation medium. Collectively, these results indicate that the 3D printed PCL/TCP scaffold promoted osteogenic differentiation of MSCs and may be widely used for bone tissue engineering. PMID- 30282428 TI - The effect of the dental root on single mandibular bone fractures. AB - BACKGROUND: This study was conducted to determine the effect of the distributional relationship between dental roots and the mandibular bone on single mandibular bone fractures, which are common craniofacial fractures. METHODS: This was a retrospective, single-center study in Seoul, Korea. Patients with single mandibular fractures in the symphysis, parasymphysis, body, and angle area, with tooth structure involvement were included. The control group included patients with simple, bone-level lacerations without fractures. In total, 94 patients (72 males and 22 females) were included in the treatment group, and 125 (71 males and 54 females) were included in the control group. The height of the mandibular bone and the dental root were measured with panoramic radiography. The central incisor represented the symphysis area, the canine represented the parasymphysis area, the first molar represented the body area, and the second molar represented the angle area. RESULTS: In the treatment group, symphysis fractures occurred in 16 patients (17%), parasymphysis fractures in 36 patients (38%), body fractures in 17 patients (18%), and angle fractures in 25 patients (27%). The ratios of the dental roots to the total height of the mandibular bone in the treatment group were 30.35%, 39.75%, 39.53%, and 36.27% for symphysis, parasymphysis, body, and angle areas, respectively, whereas in the control group, they were 27.73%, 39.70%, 36.76%, and 35.48%. The ratios of the treatment group were significantly higher than those of the control group. CONCLUSION: The results show that the higher ratio of the dental root to the height of the mandibular bone increases the fracture risk. PMID- 30282429 TI - A clinical review of reconstructive techniques for patients with multiple skin cancers on the face. AB - BACKGROUND: Cases of simultaneous multiple skin cancers in a single patient have become more common. Due to the multiplicity of lesions, reconstruction in such cases is more difficult than after a single lesion is removed. This study presents a series of patients with multiple facial skin cancers, with an analysis of the surgical removal, reconstruction process, and the results observed during follow-up. METHODS: We reviewed 12 patients diagnosed with multiple skin cancers on the face between November 2004 and March 2016. The patients' medical records were retrospectively reviewed to identify the type of skin cancer, the site of onset, methods of surgical removal and reconstruction, complications, and recurrence during follow-up. RESULTS: Nine patients had a single type of cancer occurring as multiple lesions, while three patients had different skin cancer types that occurred together. A total of 30 cancer sites were observed in the 12 patients. The most common cancer site was the nose. Thirteen defects were reconstructed with a flap, while 18 were reconstructed with skin grafting. The only complication was one case of recurrence of basal cell carcinoma. CONCLUSION: Multiple skin cancers are removed by performing Mohs micrographic surgery or wide excision, resulting in multiple defect sites. The authors emphasize the importance of thoroughly evaluating local lesions surrounding the initially identified lesions or on other sites when reconstructing a large defect which can not be covered by primary closure. Furthermore, satisfactory results can be obtained by using various methods simultaneously regarding the condition of individual patients, the defect site and size, and the surgeon's preference. PMID- 30282430 TI - Treatment of fibrous dysplasia of the zygomaticomaxillary complex with radical resection and three-dimensional reconstruction with autologous calvarial bone graft. AB - Fibrous dysplasia (FD) is a rare, benign bone disease with abnormal bone maturation and fibroblastic proliferation. Optimal treatment of zone 1 craniofacial FD is radical resection and reconstruction. To achieve of structural, aesthetic, and functional goals, we use three-dimensionally designed calvarial bone graft for reconstruction of zygomatic defect after radical resection of FD. The authors used a rapid-prototyping model for simulation surgery for radical resection and immediate reconstruction. Donor site was selected from parietal bone reflect shape, contour, and size of defect. Then radical resection of lesion and immediate reconstruction was performed as planned. Outcomes were assessed using clinical photographs and computed tomography scans. Successful reconstruction after radical resection was achieved by three-dimensional calvarial bone graft without complications. After a 12-month follow-up, sufficient bone thickness and symmetric soft tissue contour was well maintained. By considering three-dimensional configuration of zygomaticomaxillary complex, the authors achieved satisfactory structural, aesthetic and functional outcomes without complications. PMID- 30282432 TI - Sinonasal intestinal-type adenocarcinoma in the frontal sinus. AB - Sinonasal intestinal-type adenocarcinoma is a rare neoplasm which can be diagnosed by pathologic report. Nasal obstruction, epistaxis, and rhinorrhea are common symptoms, but presenting with a benign-looking palpable mass is also possible. This is a report of our experience in diagnosing and treating a sinonasal intestinal-type low grade adenocarcinoma. A 63-year-old man initially presented with a rapidly growing palpable mass in the glabella region for 4 months. A malignancy of sinus origin was suspected on imaging studies. We performed further preoperative evaluations for cancer staging, and curative surgery was planned. Radical resection and immediate reconstruction with free anterolateral thigh flap were performed. The pathology findings confirmed a diagnosis of sinonasal intestinal-type adenocarcinoma. PMID- 30282431 TI - Primary Merkel cell carcinoma of the earlobe in a young healthy man. AB - Merkel cell carcinoma (MCC) is an uncommon neuroendocrine cutaneous tumor with poor prognosis. It has the high rate of recurrence, mortality, regional nodal involvement, and distant metastases. It is difficult to diagnose MCC because of its non-specific clinical findings. It usually occurs on sun-exposed areas of the skin, mostly at head and neck. There is a difference in the incidence and prognosis according to site in the head and neck. However, there is no consented site-specific diagnosis, treatment or follow-up protocol for MCC at the head and neck. We herein report a case of MCC arising in the right earlobe of an otherwise healthy young man who has been diagnosed early, thereby successfully treated. With our closed follow-up, there was no tumor recurrence or complication at 33 months after diagnosis. PMID- 30282433 TI - Skeletal cavernous hemangiomas of the frontal bone with orbital roof and rim involvement. AB - Skeletal cavernous hemangiomas are rare, benign tumors that may involve the supraorbital rim and orbital roof. However, such involvement is extremely rare. We report a case of skeletal cavernous hemangioma of the frontal bone involving the orbital roof and rim. En bloc excision and reconstruction, using a calvarial bone graft for the orbital roof and rim defect, was performed. It is important not only to perform total excision of skeletal cavernous hemangiomas, but to properly reconstruct the defects after the total excision since several complications can arise from an orbital roof and rim defect. PMID- 30282434 TI - Treatment of post-traumatic hematoma and fibrosis using hyaluronidase injection. AB - Patients complaining of swelling and hematoma caused by contusion of the face can be easily seen in the emergency room. Most of the treatments were conservative treatments such as ice bag application, mild compression dressing, and massage. During the follow-up, fibrosis progression due to hematoma was frequently observed in the contusion site. When hematoma or fibrosis is confirmed, hyaluronidase (H-lase) 1,500 IU and 2 mL of normal saline were mixed and subcutaneously injected in crisscross manner. To evaluate the improvement of hematoma before and after hyaluronidase injection, three plastic surgeons evaluated using the Vancouver scar scale and compared preoperative and postoperative images. Hematoma and fibrosis after facial trauma improved after hyaluronidase injection for early treatment. PMID- 30282435 TI - Staged lower lip reconstruction following gangrenous stomatitis in an immunosuppressed patient. AB - A 70-year-old male with a history of diabetes mellitus, hypertension, and coronary stent insertion visited our hospital 7 days after biting his lower lip. Swelling and inflammation had worsened despite debridement and antibiotic treatment. On the 8th hospital day, fungal infection with Candida albicans and superimposed bacterial infection with Klebsiella pneumoniae were found on tissue culture. Extensive necrosis resulted in a defect of approximately 3/4 of the entire lower lip and a full-layer skin defect from the vermilion to the gingivobuccal sulcus at the right corner of the mouth. To correct drooling, incomplete lip sealing, and trismus, staged reconstruction was performed with consideration of cosmetic and functional features. The treatment process using staged reconstruction and antifungal treatment for an extensive lower lip defect caused by fungal stomatitis is described. PMID- 30282436 TI - A rare case of isolated schwannoma in infraorbital nerve. AB - A schwannoma is a benign tumor that develops from Schwann cells. It is known to occur more frequently in women than men, and about one third of schwannoma cases occur in the head and neck area. It is also known to originate mainly in the auditory nerve. However, it is rarely associated with the trigeminal nerve, and especially, schwannomas related to the infraorbital nerve are very rare. we report a rare case of a schwannoma involving the infraorbital branch of the trigeminal nerve in a 45-year old male adult. The patient underwent physical examination and magnetic resonance imaging. The mass was approached through subciliary approach that is familiar to the plastic surgeon and completely resected. Histopathological findings showed pointed to a benign schwannoma. Infraorbital nerve schwannoma is difficult to distinguish from other diseases by means of clinical symptoms, physical findings, or imaging. In spite of its rarity, infraorbital nerve schwannoma may be considered a possible diagnosis in the case of mass on cheek. Assessment by computed tomography or magnetic resonance imaging is necessary for proper diagnosis. About the surgical approach, excision through the subciliary approach should be considered rather than the direct transfacial approach in view of stability, cosmetic effects, and familiarity. PMID- 30282437 TI - New economical and simple device for intraoperative expansion on small and medium sized soft tissue defects. AB - Intraoperative expansion has been used to cover small to large defects without disadvantages of the conventional tissue expanders. Various materials, for example, expanders and Foley catheters are being used. We introduce a new, convenient and economical device immediately available in the operating room, according to the defect size for intraoperative expansion, with latex gloves or balloons. The retrospective study was done with 20 patients who presented with skin and soft tissue defects. During the operation, expansion was done with latex gloves or balloons inflated with saline through an intravenous line and a three way stopcock. After the inflation, the glove was removed and skin was covered with expanded tissue. A careful decision was made regarding the inflation volume and placement of the expander according to the defect size. There were no postoperative complications. The skin contracture and tension was minimal with a texture similar to the adjacent tissue. The new intraoperative expansion devices with latex gloves and balloons were cheap and made easily right in the operation room. The reconstruction of small to large sized skin defects can be done successfully, functionally and aesthetically without using expensive commercial materials. PMID- 30282438 TI - Histopathology of the synovial tissue: perspectives for biomarker development in chronic inflammatory arthritides. AB - The histopathological and molecular analysis of the synovial tissue has contributed to fundamental advances in our comprehension of arthritis pathogenesis and of the mechanisms of action of currently available treatments. On the other hand, its exploitation in clinical practice for diagnostic or prognostic purposes as well as for the prediction of treatment response to specific disease-modifying anti-rheumatic drugs is still limited. In this review, we present an overview of recent advances in the field of synovial tissue research with specific reference to the methods for synovial tissue collection, approaches to synovial tissue analysis and current perspectives for the exploitation of synovial tissue-derived biomarkers in chronic inflammatory arthritides. PMID- 30282439 TI - Histopathology of the muscle in rheumatic diseases. AB - The presence of muscular symptoms is common in rheumatological clinical practice, but often the differential diagnosis between muscular involvement in connective tissue diseases, vasculitis and drug-induced myopathy may be difficult. In addition to clinical assessment, laboratory analysis and instrumental examinations, muscle biopsy may help to clarify the diagnosis in patients with muscular involvement. The purpose of this review is to provide a critical analysis of the current medical literature on muscular histopathology, to help clinicians to identify when to perform muscular biopsy and to provide a practical guide to a better understanding of the pathology report. Moreover, we provide an overview of the muscular involvement and the most common histopathological findings in rheumatic diseases. PMID- 30282440 TI - Histopathology of salivary glands. AB - Salivary gland (SG) biopsy is a technique broadly applied for the diagnosis of primary Sjogren's syndrome (pSS), lymphoma accompanying SS, sarcoidosis, amyloidosis, and IgG4-related disease The most peculiar feature of pSS on biopsy is focal lymphocytic sialadenitis. In the past, several histological scores have been reported in the literature to describe glandular involvement during pSS. However, the variability among centres in reporting glandular scores is one of the rationales behind the development of standardised consensus guidance. SGs as well as lacrimal glands are involved in up to 50% of patients with IgG4-related disease with 3 histopathological hallmarks such as dense lymphoplasmacytic infiltration, storiform fibrosis and obliterative phlebitis. SGs can be also affected by amyloidosis with MSG biopsy being more sensitive than that of rectal mucosa or subcutaneous fat. SG involvement is a rare manifestation during sarcoidosis, and the presence of non-caseating granulomas needs to be differentiated from granulomas of other etiology. This review article provides an overview of normal and pathological SGs in the context of rheumatic diseases, identifying key elements in the tissue as diagnostic and prognostic biomarkers, useful in the current clinical practice. PMID- 30282441 TI - Histopathology of vasculitis. AB - The range of pathologies that are related to primitive vasculitis is broad, complex and not as typical as we would expect. Clinicians should be aware that several forms of primitive and systemic vasculitis, regardless of the size of the affected vessel, may exhibit identical histological alterations. This observation has important clinical implications as it means that cases of vasculitis do not correspond clinically and histologically. Thus, while histology remains the diagnostic gold standard, it can be used only as part of the most complete clinical assessment possible. Another point worth of the clinician's attention is that vasculitis histology changes over time, as do disease evolution and activity, even without considering the masking effects of treatment and the possibility of sampling error due to the patchy occurrence of vasculitis. The purpose of this review is to identify the most common forms of vasculitis in clinical practice, and to provide guidance to the clinician on the pathology of the vessels. PMID- 30282442 TI - Diagnostic and prognostic role of renal histopathology in rheumatic diseases. AB - The objective was to evaluate renal involvement in several rheumatic diseases (i.e. rheumatoid arthritis, systemic lupus erythematosus, Sjogren syndrome, systemic sclerosis, systemic vasculitides). The method chosen was to define histopathological profiles reported in renal biopsies performed on patients with renal involvement due to different rheumatic diseases. Renal involvement observed in patients with rheumatic disease can be the direct result of the disease per se and/or a complication of drugs used in the disease treatment. The clinical pathological correlations derived from the study of renal tissues can be useful for differential diagnosis, prognosis assessment and therapeutic decisions. Renal biopsy should be considered as an important tool for the management of nephropathies in patients with systemic rheumatic diseases. PMID- 30282443 TI - Histopathology of the gut in rheumatic diseases. AB - The gastrointestinal tract regulates the trafficking of macromolecules between the environment and the host through an epithelial barrier mechanism and is an important part of the immune system controlling the equilibrium between tolerance and immunity to non-self-antigens. Various evidence indicates that intestinal inflammation occurs in patients with rheumatic diseases. In many rheumatic diseases intestinal inflammation appears to be linked to dysbiosis and possibly represents the common denominator in the pathogenesis of different rheumatic diseases. The continuative interaction between dysbiosis and the intestinal immune system may lead to the aberrant activation of immune cells that can re circulate from the gut to the sites of extraintestinal inflammation as observed in patients with ankylosing spondylitis. The exact contribution of genetic factors in the development of intestinal inflammation in rheumatic diseases needs to be clarified. PMID- 30282444 TI - Histopathology of the skin in rheumatic diseases. AB - Rheumatological systemic autoimmune diseases, such as connective tissue diseases, rheumatoid arthritis or spondyloarthritis, are characterized by the presence of joint involvement associated with extra-articular manifestations. Among them, cutaneous diseases are often the most relevant and representative clinical manifestation, as in psoriatic arthritis, scleroderma or systemic lupus erythematosus. In this context, it is useful for rheumatologists to understand better skin diseases and their histopathological features. Evaluation of skin biopsy specimens can be helpful not only to confirm the diagnosis in both classic and clinically atypical variants, but also to improve further our knowledge of the pathogenetic mechanisms and the close link between skin and articular diseases. In this review, we discuss the clinical features, diagnostic evaluation and the histopathological features of skin manifestation of the most relevant rheumatological autoimmune diseases. PMID- 30282445 TI - The Health Burden of Cancer Attributable to Obesity in Korea: A Population-Based Cohort Study. AB - Purpose: Considering the health impact of obesity and cancer, it is important to estimate the burden of cancer attributable to high body mass index (BMI). Therefore, the present study attempts to measure the health burden of cancer attributable to excess BMI, according to cancer sites. Materials and Methods: The present study used nationwide medical check-up sample cohort data (2002-2015). The study subjects were 496,390 individuals (268,944 men and 227,446 women). We first calculated hazard ratio (HR) in order to evaluate the effect of excess BMI on cancer incidence and mortality. Then, the adjusted HR values and the prevalence of excess BMI were used to calculate the population attributable risk. This study also used the Global Burden of Disease method, to examine the health burden of obesity-related cancers attributable to obesity. Results: The highest disability-adjusted life year (DALY) values attributable to overweight and obesity in men were shown in liver cancer, colorectal cancer, and gallbladder cancer. Among women, colorectal, ovarian, and breast (postmenopausal) cancers had the highest DALYs values attributable to overweight and obesity. Approximately 8.0% and 12.5% of cancer health burden (as measured by DALY values) among obesity related cancers in men and women, respectively, can be prevented. Conclusions: Obesity has added to the health burden of cancer. By measuring the proportion of cancer burden attributable to excess BMI, the current findings provide support for the importance of properly allocating healthcare resources and for developing cancer prevention strategies to reduce the future burden of cancer. PMID- 30282446 TI - Clinical Benefit of Maintenance Therapy for Advanced Biliary Tract Cancer Patients Showing No Progression after First-Line Gemcitabine Plus Cisplatin. AB - Purpose: Gemcitabine plus cisplatin (GemCis) is the standard first line chemotherapy for patients with advanced biliary tract cancer (BTC). In ABC-02 study, the BTC patients received up to 6-8 cycles of three-weekly GemCis; however, those without progression often receive more than 6-8 cycles. The clinical benefit of maintenance treatment in patients without progression is uncertain. Materials and Methods: Advanced BTC patients treated with GemCis between April 2010 and February 2015 at Asan Medical Center, Seoul, Korea, were retrospectively analysed. The patients without progression after 6-8 cycles were stratified according to further treatment i.e. with or without further cycles of GemCis (maintenance vs observation groups). The primary endpoint was overall survival (OS) and progression-free survival (PFS). Results: Among the 740 BTC patients in the initial screen, 231 cases (31.2%) were eligible for analysis (111 in the observation group, 120 in the maintenance group). The median OS from the GemCis initiation was 20.5 months (95% confidence interval [CI], 15.4 to 25.6) and 22.4 months (95% CI, 17.0 to 27.8) in the observation and maintenance groups, respectively (p=0.162). The median PFS was 10.4 months (95% CI, 7.0 to 13.8) and 13.2 months (95% CI, 11.3 to 15.2), respectively (p=0.320). Conclusions: GemCis maintenance is not associated with an improved survival outcome. PMID- 30282447 TI - Dose-Dense Rituximab-CHOP versus Standard Rituximab-CHOP in Newly Diagnosed Chinese Patients with Diffuse Large B-Cell Lymphoma: A Randomized, Multicenter, Open-Label Phase 3 Trial. AB - Purpose: Rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisone administered every 3 weeks (R-CHOP-21) is the standard care for diffuse large B-cell lymphoma (DLBCL). It is unknown whether the dose-dense R CHOP (R-CHOP-14) could improve the outcome of the disease in Asian population. Materials and Methods: Newly diagnosed DLBCL patients were centrally, randomly assigned (1:1) to receive R-CHOP-14 or R-CHOP-21. R-CHOP-14 was administered every 2 weeks, and R-CHOP-21 was administered every 3 weeks. Primary end point was disease-free survival (DFS). Secondary end points included overall survival (OS), progression-free survival (PFS), response rate and toxicities. Results: Seven hundred and two patients were randomly assigned to receive R-CHOP-14 (n=349) or R-CHOP-21 (n=353). With a median follow-up of 45.6 months, the two groups did not differ significantly in 3-year DFS (79.6% for R-CHOP-14 vs. 83.2% for R-CHOP-21, p=0.311) , 3-year OS (77.5% for R-CHOP-14 vs. 77.6% for R-CHOP-21, p=0.903), or 3-year PFS (63.2% for R-CHOP-14 vs. 66.1% for R-CHOP-21, p=0.447). Patients with an International Prognostic Index (IPI) score >= 2 had a poorer prognosis compared to those with an IPI score <2. Grade 3/4 hematologic and non hematologic toxicities were manageable and similar between R-CHOP-14 and R-CHOP 21. Conclusion: R-CHOP-14 did not improve the outcome of DLBCL compared to R-CHOP 21 in Asian population. With manageable and similar toxicities, both of the two regimens were suitable for Asian DLBCL patients. For high-risk patients with IPI >=2, new combination regimens based on R-CHOP deserve further investigation to improve efficacy. PMID- 30282448 TI - Retrospective Study of the Significant Predictive Role of Inflammatory Degree in Initial and Repeat Prostate Biopsy Specimens for Detecting Prostate Cancer. AB - Purpose: The purpose of this study was to determine whether histologic inflammation (HI) in initial and repeat prostate biopsy specimens was significantly associated with the detection of prostate cancer. Materials and Methods: Between 2005 and 2017, the clinicopathological records of patients with high prostate-specific antigen (PSA) levels who underwent initial and repeat prostate biopsies were retrospectively reviewed. The presence of HI and its degree in each biopsied specimen were interpreted by one uropathologist with 20 years of experience. The association between HI and cancer diagnosis was statistically assessed, with p<0.05 considered significant, and the cancer and non-cancer groups were compared. Results: Among the 522 patients with a median PSA levels of 6.5 ng/dL, including 258 (49.4%) whose cancer was diagnosed following repeat biopsy, the median degrees of HI in the initial and repeat biopsies were 25.0% and 41.7%, respectively. Furthermore, 211 (40.4%) and 247 (47.3%) patients had HI (>0%) on biopsied specimens, respectively. Comparison of the cancer and noncancer groups revealed that a greater rate of HI specimens in the initial biopsy was associated with fewer prostate cancer diagnoses following repeat biopsy (p<0.001). Other comparisons between the cancer and non-cancer groups showed that the cancer group had a significantly higher rate of hypertension, whereas those non-cancer group had a significantly higher rate of benign prostatic hyperplasia and prostatitis (p<0.05). Conclusion: A finding of a lesser degree of HI in the initial and a greater degree of HI in the repeat biopsied specimens was associated with the higher probability of cancer diagnosis in patients with high PSA levels. PMID- 30282449 TI - Jab1 Silencing Inhibits Proliferation and Sensitizes to Cisplatin in Biliary Tract Cancer. AB - Purpose: Jab1 is a coactivator of c-Jun that enhances the transcriptional function of c-Jun. Jab1 is frequently overexpressed in various cancers and is associated with poor prognosis of cancer patients. Thus, Jab1 could be a potential therapeutic target in cancer. However, the role of Jab1 in biliary tract cancer (BTC) has not been studied. Materials and Methods: We performed in vitro and in vivo experiments to evaluate the therapeutic potential of Jab1 inhibition in BTC. Results: Among 8 BTC cell lines, many showed higher Jab1 expression levels. In addition, Jab1 silencing by siRNA increased p27 expression levels. SNU478 and HuCCT-1 cells exhibited profound Jab1 knockdown and increased p27 expression by Jab1-specific siRNA transfection. Jab1 silencing induced anti proliferative and anti-migratory effects and resulted in G1 cell cycle arrest in SNU478 and HuCCT-1 cells. In addition, Jab1 silencing potentiated the anti proliferative and anti-migratory effects of cisplatin by increasing DNA damage. Interestingly, Jab1 knockdown increased PTEN protein half-life, resulting in increased PTEN expression. In the HuCCT-1 mouse xenograft model, stable knockdown of Jab1 by shRNA also showed anti-proliferative effects in vivo, with decreased Ki-67 expression and AKT phosphorylation and increased Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling and p27 expression. Conclusion: Jab1 knockdown demonstrated anti-proliferative and anti-migratory effects in BTC cells by increasing DNA damage and stabilizing PTEN, resulting in G1 cell cycle arrest. In addition, Jab1 silencing potentiated the anti-proliferative effects of cisplatin. Our data suggest that Jab1 may be a potential therapeutic target in BTC that is worthy of further investigations. PMID- 30282450 TI - Comparison of the 7th and the 8th AJCC Staging System for Non-metastatic D2 Resected Lymph Node-Positive Gastric Cancer Treated with Different Adjuvant Protocols. AB - Purpose: The purpose of this study was to compare prognostic differentiation performances of the 7th and the 8th edition of American Joint Commission on Cancer (AJCC) staging system for gastric cancer (GC) patients. Materials and Methods: A total of 1,633 GC patients who underwent curative D2 resection followed by adjuvant chemotherapy alone (CA) or concurrent chemo-radiotherapy (CCRT) from 2004 to 2013 were included. Concordance index (c-index) was applied to compare the discriminatory ability. Results: In the 8th edition, migration of stage was detected in 248 (15.2%) patients. Among them, 121 patients were up staged while 127 patients were down-staged. Overall, there was no statistically significant difference in the discriminatory ability between the 7th and 8th editions. The new edition of staging system, however, showed a trend of better prognostic performance not only in recurrence-free survival (c-index = 0.734; 95% confidence interval [CI], 0.706 to 0.762 in the 7th edition vs. c-index = 0.740; 95% CI, 0.712 to 0.768 in the 8th edition; p=0.14), but also in overall survival (c-index = 0.717; 95% CI, 0.688 to 0.745 in the 7th edition vs. c-index = 0.722; 95% CI, 0.694 to 0.751 in the 8th edition; p=0.19), especially in stage III. This finding was repeated in the subgroup analysis regardless of adjuvant CA or CCRT. Conclusion: Generally, the 8th edition of AJCC staging system had failed to show a superior discriminatory ability for curatively D2 resected GC patients than the 7th edition, although there was a trend of better prognostic performance of the new edition, regardless of adjuvant treatment method. PMID- 30282451 TI - A Phage Display-Identified Peptide Selectively Binds to Kidney Injury Molecule-1 (KIM-1) and Detects KIM-1-Overexpressing Tumors in vivo. AB - Purpose: This study was carried out to identify a peptide that selectively binds to kidney injury molecule-1 (KIM-1) by screening a phage-displayed peptide library and to use the peptide for the detection of KIM-1overexpressing tumors in vivo. Materials and Methods: Biopanning of a phage-displayed peptide library was performed on KIM-1-coated plates. The binding of phage clones, peptides, and a peptide multimer to the KIM-1 protein and KIM-1-overexpressing and KIM-1-low expressing cells was examined by enzyme-linked immunosorbent assay, fluorometry, and flow cytometry. A biotin-peptide multimer was generated using NeutrAvidin. In vivo homing of the peptide to KIM-1-overexpressing and KIM-1-low expressing tumors in mice was examined by whole-body fluorescence imaging. Results: A phage clone displaying the CNWMINKEC peptide showed higher binding affinity to KIM-1 and KIM-1-overexpressing 769-P renal tumor cells compared to other phage clones selected after biopanning. The CNWMINKEC peptide and a NeutrAvidin/biotin CNWMINKEC multimer selectively bound to KIM-1 over albumin and to KIM-1 overexpressing 769-P cells and A549 lung tumor cells compared to KIM-1-low expressing HEK293 normal cells. Co-localization and competition assays using an anti-KIM-1 antibody demonstrated that the binding of the CNWMINKEC peptide to 769 P cells was specifically mediated by KIM-1. The CNWMINKEC peptide was not cytotoxic to cells and was stable for up to 24 hours in the presence of serum. Whole-body fluorescence imaging demonstrated selective homing of the CNWMINKEC peptide to KIM-1-overexpressing A498 renal tumor compared to KIM-1-low expressing HepG2 liver tumor in mice. Conclusion: The CNWMINKEC peptide is a promising probe for in vivo imaging and detection of KIM-1-overexpressing tumors.

AB - Purpose: Identification of biomarkers to predict recurrence risk is essential to improve adjuvant treatment strategies in stage II/III gastric cancer patients. This study evaluated biomarkers for predicting survival after surgical resection. Materials and Methods: This post-hoc analysis evaluated patients from the CLASSIC trial who underwent D2 gastrectomy with or without adjuvant chemotherapy (capecitabine plus oxaliplatin) at the Yonsei Cancer Center. Tumor expressions of thymidylate synthase (TS), excision repair cross-complementation group 1 (ERCC1), and programmed death-ligand 1 (PD-L1) were evaluated by immunohistochemical (IHC) staining to determine their predictive values. Results: Among 139 patients, IHC analysis revealed high tumor expression of TS (n=22, 15.8%), ERCC1 (n=23, 16.5%), and PD-L1 (n=42, 30.2%) in the subset of patients. Among all patients, high TS expression tended to predict poor disease-free survival (DFS; hazard ratio [HR], 1.80; p=0.053), whereas PD-L1 positivity was associated with favorable DFS (HR, 0.33; p=0.001) and overall survival (OS; HR, 0.38; p=0.009) in multivariate Cox analysis. In the subgroup analysis, poor DFS was independently predicted by high TS expression (HR, 2.51; p=0.022) in the adjuvant chemotherapy subgroup (n=66). High PD-L1 expression was associated with favorable DFS (HR, 0.25; p=0.011) and OS (HR, 0.22; p=0.015) only in the surgery-alone subgroup (n=73). The prognostic impact of high ERCC1 expression was not significant in the multivariate Cox analysis. Conclusion: This study shows that high TS expression is a predictive factor for worse outcomes on capecitabine plus oxaliplatin adjuvant chemotherapy, whereas PD-L1 expression is a favorable prognostic factor in locally advanced gastric cancer patients.

AB - Solar nitrogen (N2) fixation is the most attractive way for the sustainable production of ammonia (NH3), but the development of a highly active, long-term stable and low-cost catalyst remains a great challenge. Current research efforts for N2 reduction mainly focus on the metal-based catalysts using the electrochemical approach, while metal-free or solar-driven catalysts have been rarely explored. Herein, on the basis of a concept of electron "acceptance donation", a metal-free photocatalyst, namely, boron (B) atom, decorated on the optically active graphitic-carbon nitride (B/g-C3N4), for the reduction of N2 is proposed by using extensive first-principles calculations. Our results reveal that gas phase N2 can be efficiently reduced into NH3 on B/g-C3N4 through the enzymatic mechanism with a record low onset potential (0.20 V). Moreover, the B decorated g-C3N4 can significantly enhance the visible light absorption, rendering them ideal for solar-driven reduction of N2. Importantly, the as designed catalyst is further demonstrated to hold great promise for synthesis due to its extremely high stability. Our work is the first report of metal-free single atom photocatalyst for N2 reduction, offering cost-effective opportunities for advancing sustainable NH3 production. PMID- 30282454 TI - Cyclohexenynone Precursors: Preparation via Oxidative Dearomatization Strategy and Reactivity. AB - A unique approach toward the preparation of cyclohexenynone equivalents was successfully developed via oxidative dearomatization of aryne precursors, featuring multiple functionalities on the target rings. Upon activation, these in situ formed cyclohexenynone intermediates exhibit good to excellent reactivity with various trapping agents. Moreover, an unprecedented cascade was discovered with aryl allyl sulfoxides, revealing a deeper utilization of the alkyne bond by concomitantly introducing one nucleophile and two electrophiles.

PMID- 30282455 TI - Sacrificial Cobalt-Carbon Bond Homolysis in Coenzyme B12 as a Cofactor Conservation Strategy. AB - A sophisticated intracellular trafficking pathway in humans is used to tailor vitamin B12 into its active cofactor forms, and to deliver it to two known B12 dependent enzymes. Herein, we report an unexpected strategy for cellular retention of B12, an essential and reactive cofactor. If methylmalonyl-CoA mutase is unavailable to accept the coenzyme B12 product of adenosyltransferase, the latter catalyzes homolytic scission of the cobalt-carbon bond in an unconventional reversal of the nucleophilic displacement reaction that was used to make it. The resulting homolysis product binds more tightly to adenosyltransferase than does coenzyme B12, facilitating cofactor retention. We have trapped, and characterized spectroscopically, an intermediate in which the cobalt-carbon bond is weakened prior to being broken. The physiological relevance of this sacrificial catalytic activity for cofactor retention is supported by the significantly lower coenzyme B12 concentration in patients with dysfunctional methylmalonyl-CoA mutase but normal adenosyltransferase activity.

PMID- 30282461 TI - Change in Food and Beverage Availability and Marketing Following the Introduction of a Healthy Food Financing Initiative-Supported Supermarket. AB - PURPOSE: The Healthy Food Financing Initiative (HFFI) aims to expand access to healthy foods in low-resourced communities across the United States. This study examined changes in food and beverage availability and marketing in nearby small food stores after the opening of an HFFI-supported supermarket in a predominately low-income and African American community. DESIGN: Natural experiment. SETTING: Rockford, Illinois. PARTICIPANTS: A full audit was conducted of the small grocery and limited service stores located in a 1-mile radius around the new supermarket (N = 22) and a 1-square mile area within a nearby demographically matched comparison community (N = 18). Stores were audited in 2015 (1 month preopening) and 2016 (1 year afterward). MEASURES: Store characteristics, item availability, and interior and exterior promotions/advertisements were examined. ANALYSIS: Difference-in-difference (DID) regression models assessed pre- and postintervention changes in availability and marketing between small food stores in the intervention and comparison communities. RESULTS: The DID regression models indicated no difference between intervention and comparison communities with respect to changes in availability and marketing of all food items with the exception of frozen vegetables which had higher availability postintervention in the comparison community versus intervention (beta for interaction term = .67; standard error: 0.33; P = .04). CONCLUSION: After the opening of the HFFI supported supermarket, food and beverage availability and marketing in nearby small food stores did not change significantly. However, the wide range of staple foods offered by the supermarket contributed to the expansion of healthy food retail in the intervention community. PMID- 30282462 TI - Asymptomatic dislocation of a Watchman left atrial appendage occluder. AB - Device dislocation associated with left atrial appendage closure with a Watchman device is rare. Few cases of surgical treatment have been reported. Therefore, surgical options and the effects of the surgery on subsequent operations are unknown. This device was implanted in 2 patients in another hospital because of frequent brain and intestinal bleeding related to coagulation therapy for atrial fibrillation. However, routine echocardiography revealed dislocation from the left atrial appendage orifice in the early and late postoperative periods. Emergency surgical removal of the devices was performed. Perioperative device management and treatment strategies are discussed briefly. PMID- 30282463 TI - What are the determinants of a concerned vision of the future when living with type 2 diabetes? Results from the E3N-AfterDiab study. AB - Objectives Identification of characteristics associated with a negative experience with type 2 diabetes may help to develop novel intervention to improve the outlook of people with the disease. Our aim was to identify determinants of a self-reported concerned vision about the future when living with type 2 diabetes. Methods In 2630 women with type 2 diabetes from the E3N-AfterDiab study, we used multivariable logistic regression models to derive odds-ratios and 95% confidence intervals. Results Women with elevated HbA1c levels (OR = 2.42 (1.67-3.49) for >=7.2% when compared to <6.2%), or treated with injected glucose lowering treatments (OR = 1.37 [1.05-1.81]) had a higher risk of a concerned vision of the future. Age and obesity were associated with a decreased risk. Hypertension, duration of diabetes, smoking, fasting glucose levels, and years of education were not associated with a concerned vision of the future. Discussion Our findings highlight the importance of both glycemic control and the type of treatment on the perception of the future when living with type 2 diabetes. Subgroups of patients based on these characteristics may receive a specific attention from healthcare professionals to address potential concerns related with diabetes management or the fear of complications. PMID- 30282464 TI - Establishment of glycated albumin unit conversion equation from the standardized value (mmol/mol) to the routinely used value (%). AB - BACKGROUND: To promote glycated albumin standardization, the Committee on Diabetes Mellitus Indices, Japan Society of Clinical Chemistry published the recommended reference method and is supplying the reference standard material (JCCRM 611). In this study, we evaluated the basic performance of 'standardized enzymatic method' that is traceable to JCCRM 611 and established a unit conversion formula from standardized glycated albumin value (mmol/mol) to the routinely used glycated albumin value (%). METHODS: To evaluate the accuracy and within-run reproducibility of the 'standardized enzymatic method', JCCRM 611 was measured 20 times. To establish the unit conversion formula, serum specimens with known HbA1c concentrations were collected, and their glycated albumin (%) and glycated albumin (mmol/mol) were measured. RESULTS: The accuracy of glycated albumin value of the 'standardized enzymatic method' was 100.8-103.0%. The within run reproducibility CV (coefficient of variation, %) of glycated albumin value was 0.6-0.9%. In total, 240 serum specimens were collected, and the distribution of their HbA1c values was HbA1c <= 4.9% ( n = 23), 5.0-5.9% ( n = 50), 6.0-6.9%, ( n = 44), 7.0-7.9% ( n = 40), 8.0-8.9% ( n = 37) and >=9.0% ( n = 46). The unit conversion equation was defined as: GA (%) = 0.05652 * GA (mmol/mol)-0.4217 ( r = 0.999). Glycated albumin (%) calculated by the equation was in close agreement (96.6-104.2%) with the actual measured glycated albumin (%). CONCLUSIONS: The glycated albumin unit conversion formula was established from mmol/mol to %. This formula provides an easy method to convert the unit and is expected to be useful for the standardization of glycated albumin measurement. PMID- 30282465 TI - Clinical Outcomes Following Minimally Invasive Dorsal Cheilectomy for Hallux Rigidus. AB - BACKGROUND: Following failure of conservative treatment, a dorsal cheilectomy can be performed for patients in early stages of hallux rigidus by a traditional open approach or by a minimally invasive technique. We report our clinical outcomes following minimally invasive dorsal cheilectomy (MIDC). METHODS: Eighty-nine patients (98 feet) with symptomatic hallux rigidus treated between 2011 and 2016 were included in this study. The average age was 54 years. Manchester-Oxford Foot Questionnaire (MOxFQ) scores and visual analog scale (VAS) pain scores were collected. The mean follow-up was 50 months. RESULTS: The average VAS score improved from 8.0 preoperatively to 3 postoperatively. The mean MOxFQ summary index score decreased from 58.6 preoperatively to 30.5 postoperatively. All 3 MOxFQ domains also improved. Swelling took an average of 5.3 weeks to settle. There were 2 wound infections and 2 delayed wound healings. Two patients had transient nerve paraesthesia, while 2 patients had permanent numbness in the dorsomedial cutaneous nerve distribution. Twelve patients (12%) underwent reoperation, of which 7 had a first metatarsophalangeal joint arthrodesis for ongoing pain, 4 had repeat cheilectomy for residual impingement, and 1 had an open removal of loose bone. CONCLUSION: Our results suggest that MIDC resulted in improvement in patient-reported outcome measures and was a safe technique with minimal complications. The complications were similar to open cheilectomy. There was an associated learning curve as 5 of our reoperations were due to incomplete cheilectomy. Coughlin grade 1 did well with MIDC as with open cheilectomy as none went onto an arthrodesis. However, 10% (7/65) of our grade 2 and 3 cases went on to an arthrodesis.

PMID- 30282466 TI - Paclitaxel-loaded TPGS enriched self-emulsifying carrier causes apoptosis by modulating survivin expression and inhibits tumour growth in syngeneic mammary tumours. AB - Paclitaxel (PTX) in its commercial products exhibits adverse effects owing to excipients and also has poor oral bioavailability. Present work is directed towards development of tocopheryl polyethylene glycol succinate-assisted self nanoemulsifying system (SEDDS) for oral delivery of PTX. Box-Behnken design of experiment was employed to optimize PTX-SEDDS and was characterized for droplet size (29.76 +/- 2.64 nm), zeta potential (-21.46 +/- 2.52 mV), PDI (0.177 +/- 0.012), drug content (4.97 +/- 0.98 mg), entrapment efficiency (98.33 +/- 0.54%) and in vitro drug release (51.03 +/- 2.23% PTX at 72 h). PTX-SEDDS exhibited IC50; 1.58 +/- 0.12 uM and a 52.46-folds higher cell uptake in MDA-MB-231 cells along with cellular and nuclear morphology changes. Significantly higher G2M cell cycle arrest, apoptosis, mitochondrial membrane potential disruption and ROS production was exhibited by PTX-SEDDS in comparison to Taxol. Up-regulation of Bax, p21, cleaved-caspase 3, -caspase 9 and down-regulation of Bcl2 and survivin suggested apoptosis via intrinsic pathways. Pharmacokinetic study showed approximately 4-folds higher oral bioavailability of PTX-SEDDS than Taxol. Significant reduction in tumour volume and weight was observed in syngeneic mammary tumour in SD rats. Tumour histopathology and TUNEL assay showed apoptosis in tumour tissue. PTX-SEDDS caused low lung metastasis, and was safe and stable. Conclusively, PTX-SEDDS could be suitable option for oral delivery of PTX. PMID- 30282467 TI - Hydrogen atom transfer in the radical cations of tryptophan-containing peptides AW and WA studied by mass spectrometry, infrared multiple-photon dissociation spectroscopy, and theoretical calculations. AB - Two types of radical cations of tryptophan-the pi-radical cation and the protonated tryptophan-N radical-have been studied in dipeptides AW and WA. The pi radical cation produced by removal of an electron during collision-induced dissociation of a ternary Cu(II) complex was only observed for the AW peptide. In the case of WA, only the ion corresponding to the loss of ammonia, [WA-NH3] *+, was observed from the copper complex. Both protonated tryptophan-N radicals were produced by N-nitrosylation of the neutral peptides followed by transfer to the gas phase via electrospray ionization and subsequent collision-induced dissociation. The regiospecifically formed N* species were characterized by infrared multiple-photon dissociation spectroscopy which revealed that the WA tryptophan-N* radical remains the nitrogen radical, while the AW nitrogen radical rearranges into the pi-radical cation. These findings are supported by the density functional theory calculations that suggest a relatively high barrier for the radical rearrangement (N* to pi) in WA (156.3 kJ mol-1) and a very low barrier in AW (6.1 kJ mol-1). The facile hydrogen atom migration in the AW system is also supported by the collision-induced dissociation of the tryptophan-N radical species that produces fragments characteristic of the tryptophan pi radical cation. Gas-phase ion-molecule reactions with n-propyl thiol have also been used to differentiate between the pi-radical cations (react by hydrogen abstraction) and the tryptophan-N* species (unreactive) of AW. PMID- 30282468 TI - Race-Specific Patterns of Treatment Intensification Among Hypertensive Patients Using Home Blood Pressure Monitoring: Analysis Using Defined Daily Doses in the Heart Healthy Lenoir Study. AB - BACKGROUND: Racial disparities in blood pressure (BP) control persist, but whether differences by race in antihypertensive medication intensification (AMI) contribute is unknown. OBJECTIVE: To compare AMI by race for patients with elevated home BP readings. METHODS: This prospective cohort study followed adult patients from 6 rural primary care practices who used home BP monitoring (HBPM) and recorded/reported values. For providers, AMI was encouraged when mean HBPM systolic blood pressure (SBP) values were ?135 mm Hg; patients received phone based coaching on HBPM technique and sharing HBPM findings. AMI was assessed between baseline and 12 months using defined daily dose (DDD) and summed to create a total antihypertensive DDD value. RESULTS: A total of 217 patients (mean age = 61.4 +/- 10.2 years; 66% female; 57% black) provided usable HBPM data. Among 90 (41%) intensification-eligible hypertensive patients (ie, mean HBPM SBP values for 6-months ?135 mm Hg), mean total antihypertensive DDD was increased in 61% at 12 months. Blacks had significantly higher mean DDD at baseline and 12 months, but intensification (+0.72 vs +0.65; P = 0.83) was similar by race. However, intensification was greater in males than females (+1.1 vs +0.39; P = 0.031). Reduction in mean SBP following intensification was greater in white versus black patients (-8.2 vs -3.9 mm Hg; P = 0.14). Conclusion/Relevance: Treatment intensification in HBPM users was similar by race, differed significantly by gender, and may produce a greater response in white patients. Differential AMI in HBPM users does not appear to contribute to persistent racial disparities in BP control. PMID- 30282469 TI - PROMIS and FAAM Minimal Clinically Important Differences in Foot and Ankle Orthopedics. AB - BACKGROUND: Establishing score points that reflect meaningful change from the patient perspective is important for interpreting patient-reported outcomes. This study estimated the minimum clinically important difference (MCID) values of 2 Patient-Reported Outcomes Measurement Information System (PROMIS) instruments and the Foot and Ankle Ability Measure (FAAM) Sports subscale within a foot and ankle orthopedic population. METHODS: Patients seen for foot and ankle conditions at an orthopedic clinic were administered the PROMIS Physical Function (PF) v1.2, the PROMIS Pain Interference (PI) v1.1, and the FAAM Sports at baseline and all follow-up visits. MCID estimation was conducted using anchor-based and distribution-based methods. RESULTS: A total of 3069 patients, mean age of 51 years (range = 18-94), were included. The MCIDs for the PROMIS PF ranged from approximately 3 to 30 points (median = 11.3) depending on the methods being used. The MCIDs ranged from 3 to 25 points (median = 8.9) for the PROMIS PI, and from 9 to 77 points (median = 32.5) for the FAAM Sports. CONCLUSIONS: This study established a range of MCIDs in the PROMIS PF, PROMIS PI, and FAAM Sports indicating meaningful change in patient condition. MCID values were consistent across follow-up periods, but were different across methods. Values below the 25th percentile of MCIDs may be useful for low-risk clinical decisions. Midrange values (eg, near the median) should be used for high stakes decisions in clinical practice (ie, surgery referrals). The MCID values within the interquartile range should be utilized for most decision making. LEVEL OF EVIDENCE: Level I, diagnostic study, testing of previously developed diagnostic measure on consecutive patients with reference standard applied. PMID- 30282470 TI - Meta-Analysis of the Effect of Red on Perceived Attractiveness. AB - We conducted meta-analyses of studies that test the red-romance hypothesis, which is that the color red enhances heterosexual attraction in romantic contexts. For men rating women, we found a small, statistically significant effect ( d = 0.26 [0.12, 0.40], p = .0004, N = 2,961), with substantial heterogeneity, Q(44) = 172.5, pQ < .0001, I2 = 89% [82, 94], and equivocal results regarding the possibility of upward bias in the estimate. For women rating men, we found a very small effect ( d = 0.13 [0.01, 0.25], p = .03, N = 2,739), with substantial heterogeneity, Q(35) = 73.0, pQ = .0002, I2 = 53% [33, 80], and evidence of upward bias in the estimate. Moderator analyses suggest effect sizes may have declined over time (both genders), may be largest when an original shade of red is used (men only), and may be smaller in preregistered studies (women only). We present contrasting interpretations and suggestions for future research. PMID- 30282471 TI - The 'Fit for Life' exercise programme: improving the physical health of people with a mental illness. AB - People with a mental illness have very poor physical health parameters when compared to the general population. This paper outlines an exercise programme developed to improve overall fitness and curb weight gain. Seventy-two mental health service inpatients completed the general or individualised gym exercise programme within 12 weeks. Baseline and end of course physical health parameters were recorded, along with test results on a number of fitness, strength and agility tasks. No statistically significant differences were found between average pre and post programme weight scores, and weight did not increase over time. Significant differences were found on strength and agility tasks, and a decrease was observed in average resting and post exercise heart rates. Average blood pressure did not change, but the number of baseline readings indicating hypertension reduced from 14 to 8 people. The exercise programme was successful in improving the physical capacity of the individuals who participated. PMID- 30282472 TI - Does proximity to the subventricular zone and expression of CXCR-4 and nestin affect prognosis in high-grade glioma? AB - BACKGROUND: It is suspected that infiltration of stem cell areas with high-grade glioma (HGG) generates a population that compromises treatment results and survival. In this prospective study we set to assess the prognostic value of the proximity of the contrast-enhancing lesion (CEL) on MRI to the subventricular zone (SVZ) and the expression of CXCR4 and nestin as potential factors in the stem cell migration pathway. METHOD: All patients diagnosed with high-grade glioma over a three-year period from a single institution were enrolled in this prospective study. Based on MRI preoperative findings, the patients were classified into 4 Groups (I-IV) according to the proximity of the CEL on MRI to the SVZ. Histological samples were assessed with immunohistochemistry for nestin and CXCR4. Classification into groups and the presence of nestin and CXCR4 were evaluated as predictive factors for overall (OS) and progression free survival (PFS). RESULTS: Fourty patients were included in the study. In multivariate analysis, Groups II, III and IV predicted longer OS in comparison to group I (p = 0.01; p < 0.01; p < 0.01 respectively) and group III and IV predicted longer OS in comparison to group II (p < 0.01; p = 0.04 respectively). Group III predicted longer PFS than group I and II (p = 0.01; p < 0.01 respectively). The expression rates of CXCR-4 and nestin could not predict OS or PFS. CONCLUSIONS: In our study the classification according to the proximity of the contrast enhancing part of the lesion and the SVZ proved to be prognostically significant for both OS and PFS. Presence of CXCR4 or nestin was not predictive for OS or PFS. PMID- 30282473 TI - Perceptions of emotional and physical wellness among African American men as predictors of perceived overall health. AB - African American are at risk for adverse emotional health. However, due to the intersection of their racial and gender identities which heightens their masculinity, emotional wellness is not always considered a priority by and for these men. This study aimed to examine African American men's emotional and physical health in relation to their overall health. An exploratory cross sectional study was conducted to examine self-reported responses regarding emotional and physical health as predictors of overall wellness among a convenience sample of 115 African American men. The Wellness Self-Perception Questionnaire (WSPQ), a 15-item scale, was used to assess emotional and physical wellness. Overall health was assessed by a single item. Of the 115 study participants, the majority reported a positive perception of their overall health. Linear regression analyses revealed that both reported emotional wellness and physical wellness predicted better overall wellness, even when controlling for men's education and income. A review of the literature indicates this is the first study to assess emotional and physical wellness as predictors of overall health for African American men. Since African American men tend to utilize physical health services even for mental health concerns, implications for physicians are also discussed. PMID- 30282474 TI - Fishing-Related Injuries Among Pediatric Patients Treated in United States Emergency Departments, 1997 to 2016. AB - An estimated 14.8 million youth under the age of 25 years participate in recreational fishing. Despite its popularity, fishing can be associated with injuries ranging from mild to severe trauma. There is a paucity of research available that describes characteristics of fishing-related injuries among youth. We examined the National Electronic Injury Surveillance System 1997-2016 to describe injury patterns by age and sex. Linear regressions estimated changes in injuries over time. There were an estimated 412 171 pediatric patients treated in US emergency departments for fishing-related injuries. The majority of injuries occurred in males (81.4% [95% confidence interval [CI]: 80.3-82.6]) and in youth ages 11 to 18 years (53.7% [95% CI: 51.0-56.5]). Injuries were most likely due to hooks and lures (79.7% [95% CI: 75.7-83.7]), and the arm/hand accounted for 43.9% of injuries (95% CI: 42.5-45.2). Based on these findings, we suggest that injury prevention efforts should be focused on older male children and wearing appropriate clothing. PMID- 30282475 TI - PROMIS Pain Interference Is Superior vs Numeric Pain Rating Scale for Pain Assessment in Foot and Ankle Patients. AB - BACKGROUND: The Numeric Pain Rating Scale (NPRS) is a popular method to assess pain. Recently, the Patient-Reported Outcomes Measurement Information System (PROMIS) has been suggested to be more accurate in measuring pain. This study aimed to compare NPRS and PROMIS Pain Interference (PI) scores in a population of foot and ankle patients to determine which method demonstrated a stronger correlation with preoperative and postoperative function, as measured by PROMIS Physical Function (PF). METHODS: Prospective PROMIS PF and PI and NPRS data were obtained for 8 common elective foot and ankle surgical procedures. Data were collected preoperatively and postoperatively at a follow-up visit at least 6 months after surgery. Spearman correlation coefficients were calculated to determine the relationship among NPRS (0-10) and PROMIS domains (PI, PF) pre- and postoperatively. A total of 500 patients fit our inclusion criteria. RESULTS: PROMIS PF demonstrated a stronger correlation to PROMIS PI in both the pre- and postoperative settings (preoperative: rho = -0.66; postoperative: rho = -0.69) compared with the NPRS (preoperative: rho = -0.32; postoperative:rho = -0.33). Similar results were found when data were grouped by Current Procedural Terminology (CPT) code. CONCLUSION: PROMIS PI was a superior tool to gauge a patient's preoperative level of pain and functional ability. This information may assist surgeons and patients in setting postoperative functional expectations and pain management. LEVEL OF EVIDENCE: Level II, prognostic. PMID- 30282476 TI - Diet Quality and High-Sensitivity C-Reactive Protein in Patients With Systemic Lupus Erythematosus. AB - BACKGROUND AND AIMS: C-reactive protein (CRP) is commonly used as a biomarker for inflammation. Mild elevations of CRP have been seen in chronic autoimmune diseases like systemic lupus erythematosus (SLE), and CRP has been linked to an increased risk of cardiovascular events. Diet quality and certain dietary factors seem to influence CRP levels in healthy subjects. To date, the effect of diet on serum CRP in SLE has not been studied. Our aim was to investigate the relationship between dietary nutrients, antioxidant intake, and serum CRP in SLE. DESIGN AND METHOD: A cross-sectional study was conducted among 91 patients with SLE. High-sensitivity hsCRP values were determined using an immuno-turbidimetry assay in a Beckman Coulter analyzer (AU5800). Dietary intake of macro- and micronutrients was assessed through a 24-hr diet recall. Antioxidant nutrient intake was evaluated using the dietary antioxidant quality score (DAQs). Linear regression models were used to investigate the relationships between serum hsCRP levels, dietary nutrient intake, and DAQs. RESULTS: The mean serum hsCRP level observed (3.76 +/- 6.68 mg/L) was above the established normal range. However, participating SLE patients had low-quality diets, and we found no significant correlations between dietary intake of macro- or micronutrients or antioxidant nutrient intake (DAQs) and serum CRP levels. CONCLUSION: Our study reveals that participating SLE patients had a low-quality diet that did not influence inflammatory status measured using serum CRP levels. Further interventional studies with high-quality diets in this population are necessary to dissect the role of diet on CRP levels in SLE.

AB - Small-cell lung cancer (SCLC) represents the progressive form of lung cancer. Patients with SCLC have poor prognosis, partially due to drug resistance. Therefore, understanding the underlying mechanism for drug resistance in SCLC is needed to improve clinical outcomes. The concentrations of heat shock protein 90alpha (HSP90alpha) in medium were detected by enzyme-linked immunosorbent assay. The protein levels were detected by Western blot. Cell apoptosis was detected by propidium iodide staining in cell lines or terminal deoxynucleotidyl transferase dUTP nick end labeling staining in tumor sections. Doxorubicin (DOX) was administered into cultured cell lines or intraperitoneally injected into xenograft mouse to induce apoptosis. In SCLC cell lines, either DOX or ABT-737 increased extracellular HSP90alpha levels, which attenuated the percentage of apoptotic cells. Extracellular HSP90alpha activated Ak strain transforming (AKT) and beta-catenin signaling and inhibited glycogen synthase kinase 3beta (GSK3beta) signaling. In the xenograft mouse model, extracellular HSP90alpha promoted tumor development and inhibited apoptosis of tumor cells. Heat shock protein 90alpha attenuates the efficacy of anticancer drugs in SCLC cells through AKT/GSK3beta/beta-catenin signaling. PMID- 30282478 TI - The Glycosaminoglycan Content of Hip Cartilage in Osteonecrosis of Femoral Head: Evaluation with Delayed Gadolinium-Enhanced Magnetic Resonance Imaging of Cartilage. AB - Objective Hip cartilage quality is essential for the success of joint-preserving surgery for osteonecrosis. This study aimed to characterize cartilage changes in osteonecrosis of femoral head (ONFH) using delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC). Design Fifteen asymptomatic (control) and 60 ONFH subjects were included in this study. The ONFH subjects were stratified in accordance with the Association Research Circulation Osseous (ARCO) classification ( n = 15 hips per ARCO stage). All participant hips were investigated using dGEMRIC and theT1Gd data were collected and analyzed. Results T1Gd value was significantly lower in the ONFH group (365.1 +/- 90.5 ms; range 200-498 ms) compared with the control group (546.1 +/- 26.0 ms; range 504-580 ms) ( P < 0.001). The T1Gd values of ARCO stage I-IV ONFH were 460.2 +/- 17.3 ms (439 498 ms), 408.9 +/- 43.4 ms (337-472 ms), 359.9 +/- 34.5 ms (303-412 ms), 231.5 +/ 15.1 ms (200-253 ms), respectively. Decreased T1Gd value was found to correlate significantly with increased ONFH severity ( P < 0.001). T1Gd value in collapse stage was significantly lower than that of noncollapse stage (295.7 +/- 70.3 ms [range 200-412 ms] vs. 434.6 +/- 41.7 ms [range 337-498 ms]; P < 0.001). Conclusions dGEMRIC identified hip cartilage as abnormal in ONFH, even at early stage, as represented by decreased T1Gd, and this was further aggravated by ONFH collapse. PMID- 30282480 TI - Does the menstrual cycle affect the multimodal ultrasound tomography? AB - Background Multimodal ultrasound tomography (MUT) is a promising new three dimensional imaging technology for breast cancer detection without ionizing radiation or need for tissue compression. It offers an automatic scan of the pendulant whole breast. Purpose As breast tissue properties are affected by the menstrual cycle (MC), we examined whether there is an objective difference in the refractivity and attenuation images obtained via MUT at different phases of the menstrual cycle. Material and Methods Thirteen asymptomatic volunteers (age range = 27-44 years) with a regular MC were scanned once weekly for four weeks. Attenuation and refractivity images of the breast coronal slices obtained via MUT are calibrated against precisely controlled water-through values of the ultrasound waves. The average of attenuation and refractivity values measured in the MUT images were calculated for each volunteer every week. Results During the MC, the weekly averages of the refractivity images for all volunteers were 0.650% (week 1), -0.585% (week 2), -0.692% (week 3), and -0.628% (week 4), and the corresponding attenuation weekly averages were 1.712 dB/cm, 1.635 dB/cm, 1.673 dB/cm, and 1.653 dB/cm. There were no statistically significant changes during MC. Conclusion Although there are biological changes in breast tissue properties during the MC, we did not observe statistically significant changes in the average values of MUT refractivity and attenuation images in each breast for different weeks of the MC. This finding implies that the diagnostic accuracy of the MUT may not be affected by the timing of the scan during the MC. PMID- 30282479 TI - Emergency Department Presentations and Youth Suicide: A Case-Control Study. AB - OBJECTIVE: We estimate associations between emergency department (ED) diagnoses and suicide among youth to guide ED care. METHOD: This ED-based case-control study used data from the Office of the Chief Coroner and all EDs in Ontario, Canada. Cases ( n = 697 males and n = 327 females) were aged 10 to 25 years who died by suicide in Ontario between April 2003 and March 2014, with an ED contact in the year before their death. Same-aged ED-based controls were selected during this time frame. Crude and adjusted odds ratios (aORs) and 95% confidence intervals were calculated. RESULTS: Among youth diagnosed with a mental health problem at their most recent ED contact (41.9% cases, 5% controls), suicide was elevated among nonfatal self-inflicted: 'other' injuries, including hanging, strangulation, and suffocation in both sexes (aORs > 14); cut/pierce injuries in males (aOR > 5); poisonings in both sexes (aORs > 2.2); and mood and psychotic disorders in males (aORs > 1.7). Among those remaining, 'undetermined' injuries and poisonings in both sexes (aORs > 5), 'unintentional' poisonings in males (aOR = 2.1), and assault in both sexes (aORs > 1.8) were significant. At least half of cases had ED contact within 106 days. CONCLUSIONS: The results highlight the need for timely identification and treatment of mental health problems. Among those with an identified mental health problem, important targets for suicide prevention efforts are youth with self-harm and males with mood and psychotic disorders. Among others, youth with unintentional poisonings, undetermined events, and assaults should raise concern. PMID- 30282481 TI - Arterial embolization for hemoptysis in patients with chronic pulmonary tuberculosis and in patients with bronchiectasis. AB - Background Previous studies suggest that recurrence of hemoptysis after arterial embolization is associated with the underlying pulmonary disease. Purpose To compare the baseline information and imaging findings in patients with hemoptysis due to either chronic pulmonary tuberculosis (PTB) or bronchiectasis and to identify predictors of rebleeding after embolization treatment. Material and Methods Clinical data of all consecutive chronic PTB and bronchiectasis patients who underwent arterial embolization for hemoptysis from January 2010 to January 2017 in a single center were reviewed. Baseline clinical information, radiological features, and rebleeding rates were compared between patients with chronic PTB and patients with bronchiectasis. Multivariate analysis was used to identify risk factors of recurrence in each patient group. Results Seventy-six patients with chronic PTB and 97 patients with bronchiectasis were included. Male sex, pleural thickening, multiple embolized arteries, and non-bronchial systemic arterial (NBSA) blood supply were more common in chronic PTB patients. The short term and long-term recurrence-free rates were significantly lower in the chronic PTB group ( P < 0.001). For the chronic PTB group, the presence of lung destruction and shunts were independent predictors of rebleeding during follow up. Compared with patients who did not undergo computed tomography angiography (CTA) before the procedure, patients with CTA showed less recurrence in the first month after treatment ( P = 0.019). Conclusion Chronic PTB patients had more extensive NBSA blood supply and experienced higher short- and long-term recurrence rates compared with bronchiectasis patients. The risk of rebleeding was high in chronic PTB patients with lung destruction and/or shunts. PMID- 30282482 TI - The nerve root sedimentation sign in diagnosis of lumbar spinal stenosis. AB - Background The nerve root sedimentation sign is a magnetic resonance (MR) sign, shown to be present in central lumbar spinal stenosis. The lack of sedimentation of the nerve roots to the dorsal part of the dural sac is consistent with the positive nerve root sedimentation sign. Purpose To validate the reliability of the nerve root sedimentation sign in diagnosis of different grades of lumbar spinal canal stenosis. Material and Methods This study was a retrospective review of 101 consecutive MR imaging (MRI) studies obtained on patients with clinically suspected lumbar canal stenosis. Based on the minimum anteroposterior (AP) diameter of the dural sac the study sample was classified into two groups: a group with morphological lumbar spinal stenosis; and the group of patients free from stenosis (AP > 12 mm). Patients with stenosis were further subclassified based on its severity: severe stenosis (AP <= 10 mm); and moderate stenosis (AP > 10 mm to <= 12 mm). Results Positive sedimentation sign was identified in 81% of patients with severe lumbar spinal stenosis and 14% of patients with moderate stenosis. No patients without lumbar spinal stenosis had a positive nerve root sedimentation sign. Of patients with a positive nerve root sedimentation sign, 89% presented with neurological claudication. Conclusion The nerve root sedimentation is a useful tool for identification of patients with both severe clinical and morphological lumbar spinal stenosis; however, its performance in the diagnosis of patients with moderate morphological spinal stenosis is poor. PMID- 30282483 TI - Evaluation of early treatment response to radiotherapy for HCC using pre- and post-treatment MRI. AB - Background Stereotactic body radiation therapy is an emerging treatment option for patients with unresectable advanced hepatocellular carcinoma (HCC). Because liver parenchyma neighboring the tumor is unavoidably exposed to irradiation, evaluation of treatment response following radiotherapy for HCC is challenging due to increased peritumoral arterial hyperemia and delayed clearance of contrast agent in the tumor. Purpose To explore which change of magnetic resonance imaging (MRI) features between pre- and post-radiotherapy could help evaluate viability of HCC. Material and Methods Thirty-nine patients who underwent MRI before and immediately after radiotherapy for HCC were enrolled. Imaging features were assessed before and within three months after radiotherapy and changes of those imaging features were correlated with (i) tumor response at six months after radiotherapy and (ii) time to progression (TTP). Results On post-radiotherapy MRI, the short-term responders showed significantly higher incidence of negative typical HCC features including arterial enhancement with washout ( P = 0.032), hyper-intense T2 signal intensity ( P = 0.021), and hyper-intensity on DWI ( P < 0.001). On multivariate Cox hazard analysis to estimate TTP, hazard ratios of modified RECIST and disappearance of arterial enhancement with washout were 2.18 and 2.79 ( P = 0.087 and 0.029, respectively). Conclusion Disappearance of arterial enhancement with washout on post-radiotherapy would be strong features for prediction of treatment response after radiotherapy of HCC. PMID- 30282484 TI - Detection of axillary lymph node recurrence in patients with personal history of breast cancer treated with sentinel lymph node biopsy (SLNB): results of postoperative combined ultrasound and mammography screening over five consecutive years. AB - Background Sentinel lymph node biopsy (SLNB) has been accepted as the standard treatment for axillary evaluation for invasive breast cancer with a clinically negative axilla and the low rate of recurrence after SLNB was reported. Purpose To evaluate the performance of screening ultrasound (US) for breast and axillary recurrence detection in breast cancer patients who underwent SLNB. Material and Methods We identified 2807 examinations of 562 breast cancer patients who underwent SLNB and received annual screening US combined with mammography (MG) for five years. The cancer detection rate, recall rate, and positive predictive value (PPV3) of biopsies in breasts and breast plus axillae were calculated separately. Results During the five-year follow-up period, 21 patients had recurrences of breast cancer (9.8 per 1000 person-year; 95% confidence interval [CI] = 6.0-14.9), including three axillary recurrences (1.4 per 1000 person-year; 95% CI = 0.3-4.1). Screening breast US detected 12 breast cancers. The axillary scanning detected none of the axillary recurrences, but yielded 11.8 recalls per 1000 US screenings; the PPV3 for the breast and breast plus axillae were 18.3% and 15.1%, respectively. Conclusion Axillary recurrence was very rare in patient who underwent SLNB; additional axillary scanning did not provide axillary recurrence detection, but only increased the number of false-positive recalls and biopsies. PMID- 30282485 TI - Protective effects of quercetin from oxidative/nitrosative stress under intermittent hypobaric hypoxia exposure in the rat's heart. AB - BACKGROUND: Exposure to high altitude in hypobaric hypoxia (HH) is considered to be a physiological oxidative/nitrosative stress. Quercetin (Que) is an effective antioxidant and free radical scavenger against oxidative/nitrosative stress. AIMS: The aim of this study was to investigate the cardioprotective effects of Que in animals exposed to intermittent HH (IHH) and therefore exposed to oxidative/nitrosative stress. MATERIALS AND METHODS: Wistar albino male rats were exposed to short-term (2 days) or long-term (4 weeks; 5 days/week) IHH in a hypobaric chamber (5,500 m, 8 h/day, 380 mmHg, 12% O2, and 88% N2). Half of the animals received natural antioxidant Que (body weight: 30 mg/kg) daily before each IHH exposure and the remaining rats received vehicle (carboxymethylcellulose solution). Control rats were kept under normobaric normoxia (Nx) and treated in a corresponding manner. One day after the last exposure to IHH, we measured the cardiac hypoxia-induced oxidative/nitrosative stress biomarkers: the malondialdehyde (MDA) level and protein carbonyl (PC) content, the activity of some antioxidant enzymes [superoxide dismutase (SOD) and catalase (CAT)], the nitrite plus nitrate (NOx) production, and the inducible nitric oxide synthase (iNOS) protein expression. RESULTS: Heart tissue MDA and PC levels, NOx level, and iNOS expression of IHH-exposed rats had increased, and SOD and CAT activities had decreased compared with those of the Nx-exposed rats (control groups). MDA, CP, NOx, and iNOS levels had decreased in Que-treated IHH-exposed rats compared with IHH-exposed rats (control groups). However, Que administration increased SOD and CAT activities of the heart tissue in the IHH-exposed rats. CONCLUSION: HH exposure increases oxidative/nitrosative stress in heart tissue and Que is an effective cardioprotective agent, which further supports the oxidative cardiac dysfunction induced by hypoxia. PMID- 30282486 TI - Prenatal hypoxia-ischemia decreases spatial memory and increases aggression during adolescence. AB - Prenatal hypoxia-ischemia (HI) is a major cause of mortality and chronic neurological diseases in newborns. HI contributes to the emergence of several neurological disorders such as cognitive and behavioral deficits due to the atypical brain development. This study aimed at assessing the effects of prenatal HI on the spatial memory and aggression of rats during adolescence. Pregnant rats were divided into treatment and control groups. The rats of the treatment groups underwent unilateral ligation of the uterine artery on pregnancy day 7, 12, or 17. The offspring of these rats were tested for spatial memory and aggression when they reached 33 days of age. It has been found that the percentages of alternations in the Y-maze and the number of crossings in the Morris water maze tests of the HI groups were lower than those of the control groups. The total offense and defense aggression scores of the HI groups were higher than those of the control groups. In conclusion, the longer the duration of HI, the more deficits it causes in the spatial memory and aggression of rats during adolescence. PMID- 30282487 TI - Effects of results-based financing of maternal and child health services on patient satisfaction in Afghanistan. AB - Objective To examine the impact of a results-based financing programme on patient satisfaction in Afghanistan. Methods We analysed data collected from over 3000 patients from a stratified sample of 112 health facilities (56 results-based financing and 56 non-results-based financing) in 11 out of the 34 provinces of Afghanistan over a three-year period. The 112 facilities were part of 442 primary care facilities that were stratified on facility type and randomly assigned to the results-based financing (intervention) and non-results-based financing (control) groups in the 11 provinces. Data were obtained from the National Health Service Performance Assessment, a baseline survey of patients conducted in 2010, and two follow-up surveys in 2011 and 2012. Measurement of patient satisfaction used a questionnaire comprising 11 questions concerning overall satisfaction, and satisfaction with specific aspects of care, from provider behaviour (e.g. respectfulness, communication) to cleanliness, opening hours and waiting times of facilities. We used a regression adjusted difference-in-differences estimator to investigate the treatment effect on patient satisfaction at facility level. Results There were some improvements in patient satisfaction in results-based financing facilities but these were not statistically significant. In 2011, 2 out of 11 aspects of satisfaction showed 5% improvement: satisfaction with the way health care providers explained the patient's condition and treatment. In 2012, patient satisfaction was higher for almost all aspects of care in results-based financing facilities, including the two aspects on health care provider respectfulness and facility opening hours, which had been 5% lower in results based financing facilities than in non-results-based financing facilities in 2011. Overall satisfaction was almost 10% higher in results-based financing facilities than in non-results-based financing facilities in 2012. Conclusion Even if not statistically significant, observed trends suggest some positive impacts of the results-based financing programme on patient satisfaction.

PMID- 30282490 TI - Prospective study evaluating post-operative central nervous system infections following cranial surgery. AB - AIMS: To evaluate the efficacy of our methods for decreasing the incidence of post-operative central nervous system infections (PCNSI) and to assess the type of microbiology and risk factors associated with PCNSI. METHODS: This prospective study was performed at First Affiliated Hospital, College of Medicine, Zhejiang University, which is a major medical centre in eastern China. The study included adult patients who underwent cranial surgery from January 2014 to October 2015 at this institution and survived for more than 7 days . The demographic information and clinical data of the patients were recorded for every operation and the incidence of PCNSI and the type of microbiology were analysed separately for patients undergoing craniotomy and those undergoing cranial burr-hole surgery. Prior to initiation of the study, our research team had developed and implemented a series of methods for reducing infection rates in our department. RESULTS: A total of 1,616 cranial surgery procedures were assessed in the present study; 1,236 craniotomy/craniectomy operations and 380 cranial burr-hole surgery operations. Of these procedures, 29 were complicated by PCNSI (27 cases with meningitis/ventriculitis and two with intracranial abscess/empyema). The overall incidence of PCNSI was 1.8%, while the incidence of craniotomy/craniectomy operations was 2.0% (25 cases) and that of burr-hole surgery operations was 1.1% (four cases); the most common microorganism was Staphylococcus. Of the patients who underwent cranial burr-hole surgery, the only independent risk factor for PCNSI was the absence of prophylactic antibiotics. There were no independent risk factors for craniotomy/craniectomy operations. CONCLUSIONS: In the present large sample study, the incidence of PCNSI was 1.8%, which was dramatically lower than that of a previous study performed by our research group. PMID- 30282491 TI - Clinical effect of the proximity of epidural blood patch injection to the leakage site in spontaneous intracranial hypotension. AB - BACKGROUND: Epidural blood patch (EBP) has been shown to be an effective treatment option for spontaneous intracranial hypotension (SIH). We investigated whether response to the EBP was related to the distance of the injection site from the leakage site in patients with SIH. METHODS: We reviewed patients with SIH who underwent EBP at a single hospital. Patients were assigned to group R (response after EBP) or group N (no response after EBP). We then analyzed the demographics, clinical characteristics, leakage site, leakage length, EBP injection level and distance from leakage site, and injected EBP volume. RESULTS: Sixty-two patients were included in the analysis. The overall response rate to EBP was 59.7% (37 patients). The leakage length and injection distance from the leakage site did not differ between the two groups. Age, gender, body mass index, leakage site, and EBP volume did not differ significantly between the two groups. CONCLUSION: The clinical effect of EBP in SIH was not affected by leakage length or injection distance to leakage site. Further large studies must be conducted to investigate the efficacy of targeted EBP for SIH. PMID- 30282492 TI - Management of advanced heart failure: a review. AB - INTRODUCTION: Heart failure (HF) has become a global pandemic. Despite recent developments in both medical and device treatments, HF incidences continues to increase. The current definition of HF restricts itself to stages at which clinical symptoms are apparent. In advanced heart failure (AdHF), it is universally accepted that all patients are refractory to traditional therapies. As the number of HF patients increase, so does the need for additional treatments, with an increased proportion of patients requiring advanced therapies. Areas covered: This review discusses extensive evidence for the effect of medical treatment on HF, although the data on the effect on AdHF is scare. Authors review the relevant literature for treating AdHF patients. Furthermore, mechanical circulatory devices (MCD) have emerged as an alternative to heart transplantation and have been shown to enhance quality of life and reduce mortality therefore authors also review the current literature on the different MCD and technologies. Expert commentary: More patients will need advanced therapies, as the access to heart transplantation is limited by the number of available donors. AdHF patients should be identified timely since the window of opportunities for advanced therapy is narrow as their morbidity is progressive and survival is often short. PMID- 30282493 TI - "Even the fowl has feelings": access to HIV information and services among persons with disabilities in Ghana, Uganda, and Zambia. AB - BACKGROUND: Persons with disabilities have often been overlooked in the context of HIV and AIDS risk prevention and service provision. This paper explores access to and use of HIV information and services among persons with disabilities. METHODS: We conducted a multi-country qualitative research study at urban and rural sites in Uganda, Zambia, and Ghana: three countries selected to exemplify different stages of the HIV response to persons with disabilities. We conducted key informant interviews with government officials and service providers, and focus group discussions with persons with disabilities and caregivers. Research methods were designed to promote active, meaningful participation from persons with disabilities, under the guidance of local stakeholder advisors. RESULTS: Persons with disabilities emphatically challenged the common assumption that persons with disabilities are not sexually active, pointing out that this assumption denies their rights and - by denying their circumstances - leaves them vulnerable to abuse. Among persons with disabilities, knowledge about HIV was limited and attitudes towards HIV services were frequently based upon misinformation and stigmatising cultural beliefs; associated with illiteracy especially in rural areas, and rendering people with intellectual and developmental disability especially vulnerable. Multiple overlapping layers of stigma towards persons with disabilities (including internalised self-stigma and stigma associated with gender and abuse) have compounded each other to contribute to social isolation and impediments to accessing HIV information and services. Participants suggested approaches to HIV education outreach that emphasise the importance of sharing responsibility, promoting peer leadership, and increasing the active, visible participation of persons with disabilities in intervention activities, in order to make sure that accurate information reflecting the vulnerabilities of persons with disabilities is accessible to people of all levels of education. Fundamental change to improve the skills and attitudes of healthcare providers and raise their sensitivity towards persons with disabilities (including recognising multiple layers of stigma) will be critical to the ability of HIV service organisations to implement programs that are accessible to and inclusive of persons with disabilities. DISCUSSION: We suggest practical steps towards improving HIV service accessibility and utilisation for persons with disabilities, particularly emphasising the power of community responsibility and support; including acknowledging compounded stigma, addressing attitudinal barriers, promoting participatory responses, building political will and generating high-quality evidence to drive the continuing response. CONCLUSIONS: HIV service providers and rehabilitation professionals alike must recognise the two-way relationship between HIV and disability, and their multiple overlapping vulnerabilities and stigmas. Persons with disabilities demand recognition through practical steps to improve HIV service accessibility and utilisation in a manner that recognises their vulnerability and facilitates retention in care and adherence to treatment. In order to promote lasting change, interventions must look beyond the service delivery context and take into account the living circumstances of individuals and communities affected by HIV and disability. Implications for Rehabilitation Persons with disabilities are vulnerable to HIV infection but have historically been excluded from HIV and AIDS services, including prevention education, testing, treatment, care and support. Fundamental change is needed to address practical and attitudinal barriers to access, including provider training. Rehabilitation professionals and HIV service providers alike must acknowledge the two-way relationship between HIV and disability: people with disability are vulnerable to HIV infection; people with HIV are increasingly becoming disabled. Peer participation by persons with disabilities in the design and implementation of HIV services is crucial to increasing accessibility. Addressing political will (through the National Strategic Plan for HIV) is crucial to ensuring long-term sustainable change in recognizing and responding to the heightened vulnerability of people with disability to HIV. PMID- 30282494 TI - Knockdown of activated Cdc42-associated kinase inhibits human extravillous trophoblast migration and invasion and decreases protein expression of pho-Akt and matrix metalloproteinase. AB - INTRODUCTION: The sufficient invasion and migration of human extravillous trophoblast (EVTs) cells are crucial for placentation. Inadequate invasion of trophoblasts may correlate with the development of preeclampsia. Many studies have suggested that activated Cdc42-associated kinase (ACK1) is associated with tumor metastasis and invasion. This study investigated the ACK1 expression and its function in trophoblasts during placental development. METHODS: ACK1 expression in human placentas was determined through immunofluorescence. We investigated the migration/invasion of the immortalized human first-trimester EVT cell line HTR8/SVneo. Hypoxia-reoxygenation (H/R) conditions were applied to mimic preeclampsia model in vitro. Lentiviral vector-based short-hairpin RNA directed against the sequence of ACK1 (ACK1 shRNA) was used to knock down ACK1 expression in HTR8/SVneo cells. Cell apoptosis and proliferation were determined through flow cytometry and cell counting Kit-8 (CCK-8) assays, respectively. The expression of matrix metalloproteinase (MMP) 2/9 and tissue inhibitors of metalloproteinase (TIMP) 1/2 was measured by western blotting. RESULTS: ACK1 localized within trophoblasts of human placental villi, decidual cells in the maternal decidua. ACK1 levels in preeclampsia (PE) placentas were significantly lower than those in controls. ACK1 shRNA significantly inhibited HTR8/SVneo cells migration and invasion but did not affect their apoptosis and proliferation. ACK1 knockdown decreased MMP2/9 and increased TIMP1/2 expression, as well as downregulated the phosphorylation of AKt (p-Akt). In addition, ACK1 and MMP2/9 were downregulated following treatment with LY294002, whereas ACK1 shRNA had no effect on phosphorylation of PI3K(p-PI3K). After exposed in H/R condition, ACK1 expression, MMP2/9 protein, and p-Akt were also significantly decreased. DISCUSSION AND CONCLUSIONS: ACK1 expression is lowered in preeclamptic placentas and promotes trophoblast cell invasion, migration. H/R conditions decrease ACK1 expression and appear to decouple the positive relationship between ACK1 expression and Akt activation.

AB - Polymerase chain reaction (PCR) diagnosis of thalassemia usually relies on using genomic DNA. Preparing the genomic DNA can lead to sample-to-sample contamination. This report was aimed to establish the PCR protocol using whole blood for detecting mutations of alpha- and beta-globin genes causing the thalassemia syndrome. First, the PCR facilitators, betaine and bovine serum albumin (BSA), were tested, simultaneously with an adjustment of PCR thermal cycler and of whole-blood volume. Thereafter, the established whole-blood PCR was applied for detecting, in both known and unknown samples, the HBA1 Southeast Asian (- -SEA) (NG_000006.1: g.26264_45564del19301) deletion, Hb Constant Spring (Hb CS, HBA2: c.427T>C, alphaCSalpha), codon 17 (A>T) (HBB: c.52A>T), codons 41/42 (-TTCT) (HBB: c.126_129delCTTT) deletion, -28 (A>G) (HBB: c.-78A>G) and codon 26 (G>A) (Hb E or HBB: c.79G>A). It was shown that the whole-blood PCR worked successfully in 9.0% (w/v) betaine, with 1 MUL of EDTA whole blood and with addition of 10 heat-cool steps (3 min. at 94 degrees C, followed by 3 min. at 55 degrees C) prior to the typical thermal cycles for the mutations. The capability of the new whole-blood PCR was similar to that of the typical DNA based PCR. Therefore, the newly established whole-blood PCR could be performed for PCR diagnosis of thalassemia. Using this platform, sample-to-sample contamination should be eliminated. PMID- 30282497 TI - Home Care in Ontario: Perspectives on Equity. AB - Home care is an integral aspect of the Canadian health care system. Services provided to individuals allow them to live with independence and dignity within the comfort of their own residences. This article examines the historical evolution of Ontario's home care reform and the current challenges faced by staff members, patients, and their caregivers in reference to health equity. Political economy and feminist lenses are used to highlight the impact of market-based health care reforms on gendered experiences and access to home care services. Research and reports are used to critique the development of the home care system to date. Findings suggest that the current home care system is underfunded, understaffed, and inequitable in access to care. At this time, policies strategically remain blinded to the harsh realities of the home care sector in order to justify cost cutting, deregulation, and privatization of services. PMID- 30282500 TI - Using preferred fluids and different reward schedules to motivate rhesus macaques ( Macaca mulatta) in cognitive tasks. AB - Rhesus macaques ( Macaca mulatta) used in behavioural neuroscience are often required to complete cognitively complex tasks, for which a high level of motivation is essential. To induce motivation, researchers may implement fluid restriction protocols, whereby freely available water is limited, such that fluid can be used as a reward in the laboratory. A variety of different rewards and schedules are used, but there exists a lack of data assessing their effectiveness. In this study, we aimed to quantify fluid preference in rhesus macaques and to use these preferences to compare the motivational quality of different reward schedules: the monkey's previous reward (i.e. the fluid used to reward them in past studies), their new preferred reward, a variable schedule of previous and preferred reward, and a choice between the previous and preferred rewards. We found that it may be possible to reduce the level of restriction if an adequately motivating preferred reward is identified, but that this is dependent on the animal. Each monkey responded differently to both the fluid preference assessments and to the different reward schedules. As such, monkeys should not be subject to 'blanket' protocols but should be assessed individually to maintain adequate scientific data collection at the least severe level of fluid restriction. PMID- 30282499 TI - HIV blocks Type I IFN signaling through disruption of STAT1 phosphorylation. AB - This study investigates the modulation of Type I IFN induction of an antiviral state by HIV. IFNs, including IFN-alpha, are key innate immune cytokines that activate the JAK/STAT pathway leading to the expression of IFN-stimulated genes. IFN-stimulated gene expression establishes the antiviral state, limiting viral infection in IFN-alpha-stimulated microenvironments. Our previous studies have shown that HIV proteins disrupt the induction of IFN-alpha by degradation of IFN beta promoter stimulator-1, an adaptor protein for the up-regulation and release of IFN-alpha into the local microenvironment via the retinoic acid-inducible gene 1-like receptor signaling pathway. However, IFN-alpha is still released from other sources such as plasmacytoid dendritic cells via TLR-dependent recognition of HIV. Here we report that the activation of the JAK/STAT pathway by IFN-alpha stimulation is disrupted by HIV proteins Vpu and Nef, which both reduce IFN-alpha induction of STAT1 phosphorylation. Thus, HIV would still be able to avoid antiviral protection induced by IFN-alpha in the local microenvironment. These findings show that HIV blocks multiple signaling points that would lead to the up regulation of IFN-stimulated genes, allowing more effective replication in IFN alpha-rich environments. PMID- 30282498 TI - Surgical management of coincidental metastases to upper cervical spine and skull from hepatocellular carcinoma: a case report. AB - Metastases to the skull or upper cervical spine from hepatocellular carcinoma (HCC) are very rare. We herein report a unique case of two-site surgery for both skull and upper cervical spine metastases from HCC. The patient was a 64-year-old man with cervical pain. Computed tomography (CT) revealed osteolytic change related to metastatic cervical spine and occipital bone tumors. Two-stage surgery involving posterior occipitocervical fusion and occipital bone tumor resection was performed. The patient's pain decreased in severity, and postoperative radiotherapy and chemotherapy could be conducted. The postoperative course was favorable, and the patient exhibited improvement in his activities of daily living. Neither cervical spine X-ray examination nor CT showed any instrumentation failure, such as screw loosening, before the patient died of liver failure 13 months after surgery. Patients with both skull and upper cervical spine metastases from liver cancer may have a markedly unfavorable prognosis. Even in these patients, however, surgery as an aggressive palliative treatment may prolong the survival period or maintain the quality of life as long as the patient's general condition permits. PMID- 30282501 TI - Peripheral arterial tonometry and angiogenic biomarkers in preeclampsia. AB - OBJECTIVE: To evaluate changes in vascular function and serum biomarkers in women with and without preeclampsia (PE) to create a model for the easier and more precise diagnosis of PE in the future. METHODS: Endothelial function and arterial stiffness were evaluated using peripheral arterial tonometry and concentrations of placental growth factor (PlGF), soluble fms like tyrosine kinase 1 (sFlt-1) and soluble endoglin (sEng) were determined by immunoassay. RESULTS: Arterial stiffness deteriorates and endothelial function is better in women with PE compared with a healthy pregnancy. Women who developed PE had a decreased PlGF and PlGF/(sFlt-1+ sEng) ratio and an increased sEng, and sFlt-1/PlGF ratio. CONCLUSION: Peripheral arterial analysis did provide additional information beyond serum biomarkers in the diagnosis of PE.

AB - BACKGROUND:: The pretreatment prognostic nutritional index has been considered a potential prognostic biomarker in patients with non-small cell lung cancer (NSCLC), but this remains controversial. Therefore, we performed a meta-analysis to systematically assess the prognostic value of the prognostic nutritional index in patients with NSCLC. METHODS:: We systematically searched PubMed, EMBASE, Web of Science, and CNKI. The hazard ratios (HRs) with their corresponding 95% confidence intervals (CIs) were used to evaluate the link between the prognostic nutritional index and the oncological outcomes of patients with NSCLC, including overall survival, disease-free survival/recurrence-free survival, and progression free survival. RESULTS:: Fifteen studies were included in this meta-analysis. Twelve of these studies explored the association between the prognostic nutritional index and the overall survival of patients with NSCLC. Our pooled analysis indicated that a low prognostic nutritional index was significantly related to adverse overall survival (HR 1.61; 95% CI 1.44, 1.81; P < 0.001). Our results also showed that the prognostic nutritional index was a negative predictor for disease-free survival/recurrence-free survival, and progression free survival in patients with NSCLC. CONCLUSION:: Our meta-analysis demonstrated that there was a close association between the prognostic nutritional index value and prognosis in NSCLC patients and that the prognostic nutritional index may act as a useful prognostic biomarker in NSCLC patients. PMID- 30282504 TI - Synchronous microsurgical anastomosis in complex replantation surgery. AB - We conducted a retrospective case control study of digital replantations in 16 patients from September 2015 to January 2017. Half of the patients were treated by a synchronous microsurgical technique and the other half underwent conventional micro-anastomoses. The total time for anastomoses, total operation time and survival of digits were the major endpoints in this study. The number of digits replanted and the anastomosis method had significant effects on total anastomosis time. The mean anastomosis time for each digit was 46 min and 70 min in the synchronous and conventional groups, respectively, a 34% reduction in anastomosis time in the synchronous group when compared with the conventional group. Patency rates were 87% (13/15) of all the digits replanted in each group. Level of evidence: IV. PMID- 30282505 TI - MRI at term equivalent age for predicting long term neuro-developmental outcome in preterm infants - A cohort study. AB - INTRODUCTION: Preterm infants are at increased risk of adverse neuro developmental outcome (NDO). Cranial ultrasound has limited predictability. The aim of the study is to evaluate whether MRI done at term equivalent age (TEA) predicts NDO at 18-22 months of corrected gestational age (CGA). METHOD: This cohort study of preterm infants born at <= 32 weeks of gestation and/or birth weight < 1500 grams between April 2011 and August 2012, was conducted in a tertiary care institute in India. MRI done at TEA was reported using objective scoring. NDO at 18-22 months CGA was assessed using Bayley Scale of Infant Development version III (BSID) III. Composite score (CS) < 85 in motor, language or cognition domain was taken as adverse NDO. Association between individual MRI subscores and NDO was evaluated using multiple linear regressions by backward elimination method. Validity of MRI abnormality in predicting adverse NDO was assessed. RESULTS: Out of 94 infants who had MRI at TEA, 56 (60%) underwent BSID III. Mean gestational age was 29.8 +/- 2.1 weeks. Median score of all domains were lower with higher total MRI score. Predictive accuracy for various subscores ranged from 55 to 73%. By multiple regression analysis, signal abnormality was associated with motor delay (beta -8.4; p 0.02) and cystic white matter (WM) changes with motor delay (beta -7.3; p 0.003) and cognitive delay (beta -6.1; p 0.005). CONCLUSIONS: Although specificity and negative predictive value were moderate to high across all subscores in MRI to predict the NDO, the accuracy has been only low to moderate, which limits its use as sole predictor. PMID- 30282506 TI - Embracing Transparency Through Data Sharing. AB - Low rates of reproducibility and translatability of data from nonclinical research have been reported. Major causes of irreproducibility include oversights in study design, failure to characterize reagents and protocols, a lack of access to detailed methods and data, and an absence of universally accepted and applied standards and guidelines. Specific areas of concern include uncharacterized antibodies and cell lines, the use of inappropriate sampling and testing protocols, a lack of transparency and access to raw data, and deficiencies in the translatability of findings to the clinic from studies using animal models of disease. All stakeholders-academia, industry, funding agencies, regulators, nonprofit entities, and publishers-are encouraged to play active roles in addressing these challenges by formulating and promoting access to best practices and standard operating procedures and validating data collaboratively at each step of the biomedical research life cycle. PMID- 30282507 TI - A microcomputed tomography evaluation of the shaping ability of three thermally treated nickel-titanium rotary file systems in curved canals. AB - Objective To evaluate the shaping ability of three thermally-treated rotary nickel-titanium (NiTi) systems including ProTaper Next (PTN), HyFlexTM CM (HFCM) and HyFlexTM EDM (HFEDM) during root canal preparation in simulated root canals. Methods A total of 45 simulated root canals were divided into three groups ( n = 15) and prepared with PTN, HFCM or HFEDM files up to size 25. Microcomputed tomography (microCT) was used to scan the specimens before and after instrumentation. Volume and diameter changes, transportations and centring ratios at 11 levels of the simulated root canals were measured and compared. Results HFEDM caused significantly greater volume increases than HFCM and PTN in the entire root canal and in the apical and middle thirds. HFCM removed the least amount of resin in the coronal third compared with HFEDM and PTN. Overall, HFCM caused significantly less transportation in the apical 2 mm and was better centred than PTN in the apical 3 mm. Conclusion Under the conditions of this study, all systems prepared curved canals without significant shaping errors and instrument fracture. PTN and HFCM cut less resin than HFEDM. HFCM stayed centred apically and cut the least material coronally.

PMID- 30282510 TI - The Use of a Novel Super-Oxidized Solution on Top of Standard Treatment in the Home Care Management of Postsurgical Lesions of the Diabetic Foot Reduces Reinfections and Shortens Healing Time. AB - There are still many unmet needs in the treatment of chronic wounds, especially regarding microenvironment modulation. Nexodyn is a novel super-oxidized solution capable of contrast bacterial proliferation. We aimed to evaluate if this solution, on top of standard of care, was safe and effective in improving diabetic foot outcome. We selected 50 patients admitted in our department to be submitted to surgery for acute diabetic foot infection. All patients were left open to heal for secondary intent. We divided patients into 2 groups: Group A (n = 25, male/female = 17/8, age = 67.3 +/- 12.1 years, hemoglobin A1C = 7.9 +/- 1.1%), patients treated with standard of care and, on top of this, Nexodyn solution, and Group B, treated only with standard of care. After discharge, patients continued Nexodyn application. We followed up patients until complete healing or up to 6 months. No differences between groups in healing rate, while time required for complete healing was significantly shorter in Group A (64.9 +/- 12.1 days vs 147.4 +/- 23.1 days, P < .01). During follow-up, the group treated with Nexodyn showed a reduced rate of reinfections (12 patients in Group B vs 3 patients in Group A, P < .05) and of further debridement procedures (1 patient in Group A vs 10 patients in Group B, P < .05). Nexodyn provided effective protection against reinfections in diabetic foot patients, thus reducing the necessity for debridement procedures and their healing time and presents a safety profile similar to saline solution. PMID- 30282508 TI - Differences in secretome in culture media when comparing blastocysts and arrested embryos using multiplex proximity assay. AB - OBJECTIVES: The aim of this study was to assess different patterns of the human embryo secretome analysed as protein levels in culture media. Furthermore, analyses to correlate protein levels with quality and timing to development of human embryos were performed. MATERIAL AND METHODS: Human day-2 cryopreserved embryos were cultured for four days in an EmbryoScope(r) with a time-lapse camera, and embryo quality was evaluated retrospectively. After culture, the media were collected and relative levels of secreted proteins were analysed using Proseek Multiplex Assays. Protein levels were evaluated in relation to timing to development and the ability to form a blastocyst. RESULTS: Specific patterns of timing of development of blastocysts were found, where a difference in time to start of cavitation was found between high- and low-quality blastocysts. There appeared to be a correlation between specific protein patterns and successful formation of morulae and blastocysts. Embryos developing into blastocysts had higher levels of EMMPRIN than arrested embryos, and levels of caspase-3 were lower in high- versus low-quality blastocysts. Also, higher levels of VEGF-A, IL 6, and EMMPRIN correlated with shorter times to morula formation. CONCLUSIONS: The secretome and timing to development differ in embryos forming blastocysts and those that become arrested, and in high- versus low-quality blastocysts. The levels of certain proteins also correlate to specific times to development. PMID- 30282511 TI - Has the implementation of the Minamata convention had an impact on the practice of operative dentistry in Jordan? AB - Objective To assess Jordanian dentists' current perception and attitudes towards amalgam and composite restorations four years after the Minamata treaty was endorsed and suggest decision making factors that may influence the type of restoration requested by patients. Methods The cross-sectional study was conducted through structured questionnaires distributed to dentists in Amman, Jordan from June 2017 to February 2018. Results Of the 1686 dentists who were contacted 758 dentists (response rate 45%) responded to the questionnaire either by email or via field visits. Jordanian dentists used more composite restorations than amalgam. Recurrent caries followed by fracture of the restoration were the main reasons for replacement of both fillings by dentists. However, dentists suggested that the main reason patients requested replacement of amalgam was for 'staining'. In addition, a large proportion of the dentists had experienced patients who had asked either for replacement of amalgam (77%) or refused an amalgam filling (99%) for aesthetic reasons. In the opinion of the dentists, only 20% patients requested replacement of amalgam because of the mercury content. Conclusion The findings of this survey suggest that a 'phase-down' of dental amalgam is being implemented in Jordan's dental clinics but it is not associated with commitment to the Minamata Convention, rather to current dental practice trends and patients' aesthetic demands.

PMID- 30282513 TI - Resting-State Functional Connectivity of the Habenula in Mood Disorder Patients With and Without Suicide-Related Behaviors. AB - The habenula is a small midbrain structure that is important for brain signaling and learning from negative events. Thus, the habenula is strongly connected to both the reward system and motor regions. Increasing evidence suggests a role for the habenula in the etiology of psychiatric disorders, including mood and substance use disorders. However, no studies to date have investigated habenular resting-state functional connectivity (rsFC) in suicide-related behaviors (SB). The authors enrolled 123 individuals with major depressive disorder (MDD) or bipolar disorder and a history of suicide-related behaviors (SB+), 74 individuals with MDD or bipolar disorder and a history of suicidal ideation but no history of SB (SB-), and 75 healthy control subjects (HC). A seed-based approach was used to identify regions showing different rsFC with the habenula followed by region of interest to region of interest post hoc comparisons. Compared with both the SB- and HC groups, the SB+ group showed higher connectivity between the left habenula and the left parahippocampal gyrus, the right amygdala, and the right precentral and postcentral gyri. Patients with mood disorders displayed higher rsFC between the left habenula and left middle temporal gyrus, the left angular gyrus, and the left posterior cingulate cortex, as well as lower rsFC between the right habenula and the left thalamus, when compared with HCs. These findings suggest that the habenula is involved in the neural circuitry of suicide. The higher habenular rsFC found in the SB+ group may mediate a dysfunction in the mechanism that links the habenula with motor activity and contextual associative processing.

PMID- 30282515 TI - Thrombophilic risk factors are laterally associated with Apolipoprotein E gene polymorphisms in deep vein thrombosis patients: An Indian study. AB - Introduction Deep vein thrombosis is a multifactorial disease with many acquired and genetic risk factors. Polymorphism in the APOE gene is an upcoming potential pathogenic factor whose role is unclear in deep vein thrombosis. Methods An equal number of deep vein thrombosis cases and controls (N = 100, each) were investigated for APOE gene polymorphisms along with known acquired and hereditable thrombophilic risk factors. APOE genotyping was done by polymerase chain reaction. Results The epsilon3/epsilon4 and epsilon2/epsilon3 APOE genotypes were commoner in deep vein thrombosis cases than controls but not statistically significant ( epsilon3/epsilon4 -> 18% versus 11%, OR = 1.776, CI = 0.792-3.984, p = 0.16; epsilon2/epsilon3 ->10% versus 9%, OR = 1.123, CI = 0.436 2.895, p = 0.809). However, the following risk factors were found to be laterally associated with APOE genotypes in cases of deep vein thrombosis: pregnancy with epsilon2/epsilon3 genotype positivity (N = 29; p = 0.019), recurrent pregnancy loss with epsilon3/epsilon3 genotype (N = 29; p = 0.016), normal antithrombin levels with epsilon3/epsilon3 genotype (N = 62; p = 0.03) and non-O blood group with epsilon3/epsilon4 genotype (N = 100; p = 0.023). Conclusion APOE genotypes have shown only a modest association with deep vein thrombosis and were not statistically significant. A lateral association of these genotypes with thrombophilic risk factors was observed which may be investigated further for the possible pathogenetic mechanisms and their therapeutic implications. PMID- 30282516 TI - Dietary factors and their association with childhood obesity in the Middle East: A systematic review. AB - BACKGROUND: Childhood obesity is a global epidemic that is related to environmental and genetic factors and has adverse consequences throughout life, being obese is a serious health problem in childhood and increases the risk of many co-morbidities. AIM: The purpose of this systematic review is to illustrate that dietary factors correlate with obesity among children studied in the Middle East area. METHODS: Studies were screened by searching two databases in August 2017 and considered as eligible for inclusion if they: (a) are observational studies, (b) define at least one dietary factor for obese children aged 6-12 years, (c) are undertaken in the Middle East area, and (d) are written in English. The search dependent words and terms used are: diet, nutrition, pediatric obesity, physical activity, Middle East, overweight, children, excess weight, childhood, obesity and dietary factors. Papers were initially evaluated for eligibility based on title and abstract. The full text of articles of studies that met, or appeared to meet, the inclusion criteria, were saved. Quality assessment was conducted using the NIH tool for observational cohort and cross sectional studies. Out of 730 studies, 4 papers met the inclusion criteria and rated as good quality. These studies were from Iran ( n=2), Saudi Arabia ( n=1) and Lebanon ( n=1) during 2008 and 2016. RESULTS: Dietary factors identified were breakfast intake, junk-food consumption, energy intake and micronutrient intake. The present systematic review shows that several dietary behaviors such as missing breakfast, excessive fat and refined carbohydrate intake with low micronutrient intake due to low consumption of fruits, vegetables and milk/diary, are associated with obesity in children in the Middle East. CONCLUSIONS: A healthy diet during childhood to control weight and prevent obesity is recommended for a healthy, lifelong adulthood. PMID- 30282517 TI - Age-related changes in word retrieval vary by self-reported anxiety but not depression symptoms. AB - Tip-of-the-tongue states (TOTs) are known to increase in frequency across adulthood, but there is wide variability in older adults' TOT rates, suggesting that individual difference factors contribute to TOT incidence. We investigated the role of affect by examining the relationship between self-reported anxiety and depression symptoms and the frequency of TOTs during a laboratory task. Participants were young, middle-aged and older adults in a population-based sample of adults aged 18-87. Increased anxiety was associated with fewer TOTs for the middle-aged group but more TOTs for the older adult group. There was no relationship between anxiety and TOTs for younger adults and no relationships between depression symptoms and TOT incidence for any age group. We discuss our results in terms of attentional control theory, which provides an explanation of how age may affect the relationship between anxiety and TOTs. PMID- 30282519 TI - Two case reports of Wellens' syndrome. AB - Wellens' syndrome is characterised by particular changes in electrocardiogram (ECG) precordial lead T-waves accompanied by proximal stenosis of the left anterior descending (LAD) artery. Two cases of electrocardiographic changes associated with Wellens' syndrome are presented here. Case 1, a 55-year-old female, was transferred to the First Affiliated Hospital of Xi'an Jiaotong University with intermittent and laborious angina pectoris. Her first ECG on admission revealed T-wave inversion in leads V1-V3 and biphasic T-waves in V4. Case 2, an 85-year-old female, presented with dyspnoea and paroxysmal chest pain. Her admission ECG displayed asymmetrical T-wave inversion in leads V1-V3, I, and aVL, and depressed ST segments in leads V2-V5. In this patient, drug-eluting stents were placed on a LAD artery lesion and right coronary artery occlusion. The potential of ECGs to aid decision-making in severe myocardial infarction is straightforward, particularly in patients with characteristic ECGs, however, Wellens' syndrome has a wide spectrum of clinical manifestations and the ECG patterns may manifest itself persistently over a period of weeks. Therefore, ECG parameters should be combined with coronary angiography to confirm the presence of lesions. PMID- 30282518 TI - Immune response and differentially expressed proteins in the lung tissue of BALB/c mice challenged by aerosolized Brucella melitensis 5. AB - OBJECTIVE: This study was performed to develop a murine aerosol infection model of brucellosis to investigate the pathogenicity and immune reactions induced by aerosolized Brucella and to identify key proteins associated with Brucella infection in lung tissue. METHODS: BALB/c mice were exposed to aerosolized Brucella melitensis 5 (M5) for 30 minutes and killed at 1, 3, 7, and 15 days post exposure. Clinical observation, pathological analysis of lung tissue, and cytokine expression detection were then performed. Proteomic analysis based on two-dimensional electrophoresis and mass spectrometry was used to identify proteins exhibiting significant changes in expression in lung tissues during Brucella infection. RESULTS: Pathological analysis revealed alveolar wall thickening, telangiectasia with hyperemia, inflammatory cell infiltration, large areas of congestion and bleeding, and areas of focal necrosis. The T-helper 1 type immune response played an important role during aerosol infection, and 12 differentially expressed proteins were involved in the infectious process in lung tissue. CONCLUSION: These results contribute to our understanding of the pathogenic process of Brucella in the lung tissue of BALB/c mice challenged with aerosolized Brucella. Some of the identified proteins may be potential targets in future therapeutic strategies. PMID- 30282520 TI - Effect of once-only flexible sigmoidoscopy screening on the outcomes of subsequent faecal occult blood test screening. AB - Objective To investigate the outcomes of biennial guaiac faecal occult blood test (gFOBT) screening after once-only flexible sigmoidoscopy (FS) screening. Methods Between 1994 and 1999, as part of the UK FS Screening Trial (UKFSST), adults aged 55-64 were randomly allocated to an intervention group (offered FS screening) or a control group (not contacted). From 2006, a subset of UKFSST participants (20,895/44,041 intervention group; 41,497/87,149 control group) were invited to biennial gFOBT screening by the English Bowel Cancer Screening Programme. We analysed gFOBT uptake, test positivity, yield of colorectal cancer (CRC), and positive predictive value (PPV) for CRC, advanced adenomas (AAs), and advanced colorectal neoplasia (ACN: AA/CRC). Results Uptake of gFOBT at first invitation was 1.9% lower (65.7% vs. 67.6%, p < 0.01) among intervention versus control group participants. Positivity was 0.4% lower (2.0% vs. 2.4%, p < 0.01) and CRC yield was 0.08% lower (0.19% vs. 0.27%, p = 0.14). PPVs were also lower in the intervention versus control group, at 10.3% vs. 12.3% ( p = 0.44) for CRC, 22.7% vs. 31.4% ( p < 0.01) for AA, and 33.0% vs. 43.7% ( p < 0.01) for ACN. Among those who refused FS ( n = 5532), gFOBT uptake at first invitation was 47.7%, CRC yield was 0.25%, and PPV for ACN was 46.2%. Among FS attenders ( n = 15,363), uptake was 72.2%, CRC yield was 0.18%, and PPV for ACN was 27.9%. Conclusions Uptake, positivity and PPV of gFOBT screening were reduced following prior offer of FS screening. However, a quarter of FS screened participants receiving a diagnostic examination after positive gFOBT were diagnosed with ACN. PMID- 30282521 TI - Hospital Practices for Parents Following Perinatal Loss. AB - The aim of this study is to provide comprehensive and current information on hospital practices following perinatal death. The provinces with the highest number of hospitals in Turkey were selected for the study. To collect data, the questionnaire form of Canadian hospitals maternity policies and practices survey was sent to the appropriate respondents in hospitals. The study showed that encouraging parents to have photos of the deceased baby and preparing a remembrance pack were the most problematic issues and were not available at the majority of hospitals. The most common supportive practices in hospitals were the opportunity to see the deceased baby, assisting with funeral options and autopsies, and support for completing the necessary legal documents. The result indicated that hospitals implement varied practices in assisting the bereaved parents. The study recommended developing hospital policies and practices related to perinatal death and supporting families during their loss and grief. PMID- 30282522 TI - Feature binding in short-term memory and long-term learning. AB - In everyday experience, we encounter visual feature combinations. Some combinations are learned to support object recognition, and some are arbitrary and rapidly changing, so are retained briefly to complete ongoing tasks before being updated or forgotten. However, the boundary conditions between temporary retention of fleeting feature combinations and learning of feature bindings are unclear. Logie, Brockmole, and Vandenbroucke demonstrated that 60 repetitions of the same feature bindings for change detection resulted in no learning, but clear learning occurred with cued recall of the feature names. We extended those studies in two new experiments with the same array of colour-shape-location combinations repeated for 120 trials. In Experiment 1, change detection was well above chance from Trial 1, but improved only after 40 to 60 trials for participants who subsequently reported becoming aware of the repetition, and after 100 to 120 trials for participants reporting no awareness. Performance improved rapidly in Experiment 2 when participants reconstructed the array by selecting individual features from sets of colours, shapes, and locations. All participants subsequently reported becoming aware of the repetition. We conclude that change detection involves a visual cache memory that functions from the first trial, and retains feature bindings only for the duration of a trial. In addition, a weak residual episodic memory trace accumulates slowly across repetitions, eventually resulting in learning. Reconstructing feature combinations generates a much stronger episodic memory trace from trial to trial, and so learning is faster with performance supported both by the limited capacity visual cache and learning of the array. PMID- 30282523 TI - Binding of Platinum Derivative, Oxaliplatin to Deoxyribonucleic Acid: Structural Insight into Antitumor Action. AB - Platinum derived chemodrugs constitute an active class in cancer therapeutics. Besides being potent against various solid tumors, oxaliplatin has been recognized as first platinum compound to be approved for the treatment of colorectal cancer. Structurally, oxaliplatin consists of a platinum metal complexed to oxalate and diaminocyclohexane (DACH) and exert its anticancer action by inhibiting DNA replication and transcription. The present study highlights the binding properties of oxaliplatin with calf thymus DNA using spectroscopic methods to comprehend its binding mechanism at molecular level to overcome associated cellular resistance and side-effects. Attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopic outcomes confirm that oxaliplatin is a covalent binding agent and also provide sequence specificity in DNA molecule. Infrared spectral results further indicate that oxaliplatin alkylates purine nitrogenous bases majorly guanine residues (G) in the major groove via formation of either interstrand or intrastrand guanine guanine d(GpG) and guanine-adenine d(GpA) (N7 position) crosslinks accompanied with slight external binding to sugar-phosphate backbone. Again, circular dichroism (CD) spectroscopic results suggest subtle conformational changes in DNA molecule due to its complexation with oxaliplatin and duplex attains an intermediate conformational state having characteristics of both B- and C-form. Further, moderate binding strength of 4.12+/-0.2 * 104 M-1 for the interaction has been estimated via ultraviolet-visible spectroscopy. The inferences obtained from these investigations are encouraging and can form the basis for further exploration in the field of rational drug development based on platinum compounds possessing preferential binding for nucleic acid with improved competence. PMID- 30282524 TI - Immunopathogenesis of Acute Kidney Injury. AB - Pathophysiologically, the classification of acute kidney injury (AKI) can be divided into three categories: (1) prerenal, (2) intrinsic, and (3) postrenal. Emerging evidence supports the involvement of renal tubular epithelial cells and the innate and adaptive arms of the immune system in the pathogenesis of intrinsic AKI. Pro-inflammatory damage-associated molecular patterns, pathogen associated molecular patterns, hypoxia inducible factors, toll-like receptors, complement system, oxidative stress, adhesion molecules, cell death, resident renal dendritic cells, neutrophils, T and B lymphocytes, macrophages, natural killer T cells, cytokines, and secreted chemokines contribute to the immunopathogenesis of AKI. However, other immune cells and pathways such as M2 macrophages, regulatory T cells, progranulin, and autophagy exhibit anti inflammatory properties and facilitate kidney tissue repair after AKI. Thus, therapies for AKI include agents such as anti-inflammatory (e.g., recombinant alkaline phosphatase), antioxidants (iron chelators), and apoptosis inhibitors. In preclinical toxicity studies, drug-induced kidney injury can be seen after exposure to a nephrotoxicant test article due to immune mechanisms and dysregulation of innate, and/or adaptive cellular immunity. The focus of this review will be on intrinsic AKI, as it relates to the immune and renal systems cross talks focusing on the cellular and pathophysiologic mechanisms of AKI. PMID- 30282525 TI - Decay of internal reference information in duration discrimination: Intertrial interval modulates the Type B effect. AB - Psychophysical evidence suggests that human perception of a stimulus is assimilated towards previous stimuli. The internal reference model (IRM) explains such assimilation through an internal reference (IR), which integrates past and present stimulus representations and thus might be conceived as a form of perceptual memory. In this study, we investigated whether the IR decays with time, as previously shown for perceptual memory representations in general. One specific prediction of IRM is higher discrimination sensitivity when a constant standard precedes rather than follows a variable comparison in a two-alternative forced-choice (2AFC) discrimination task. Furthermore, the magnitude of this so called negative Type B effect should decrease with decreasing weighting of past stimulus information in the integration process. Therefore, decay of the IR should result in a reduced Type B effect. To examine this prediction, we carried out a 2AFC duration discrimination experiment with a short (1,600 ms) and a long (3,200 ms) intertrial interval (ITI). As expected, a reduced negative Type B effect was observed at the long compared with the short ITI, consistent with the idea that humans rely on the immediate past when evaluating current sensory input, however, less so when the IR incorporating the perceptual short-term memory representation of these past stimuli has already decayed. PMID- 30282526 TI - The ability to recognise emotions predicts the time-course of sarcasm processing: Evidence from eye movements. AB - A core feature of sarcasm is that there is a discrepancy between the literal meaning of the utterance and the context in which it is presented. This means that a sarcastic statement embedded in a story introduces a break in local coherence. Previous studies have shown that sarcastic statements in written stories often elicit longer processing times than their literal counterparts, possibly reflecting the difficulty of integrating the statement into the story's context. In the present study, we examined how sarcastic statements are processed when the location of the local coherence break is manipulated by presenting the sarcastic dialogues either before or after contextual information. In total, 60 participants read short text paragraphs containing sarcastic or literal target statements, while their eye movements were recorded. Individual differences in ability to recognise emotions and working memory capacity were measured. The results suggest that longer reading times with sarcastic statements not only reflect local inconsistency but also attempt to resolve the meaning of the sarcastic statement. The ability to recognise emotions was reflected in eye movement patterns, suggesting that readers who are poor at recognising emotions are slower at categorising the statement as sarcastic. Thus, they need more processing effort to resolve the sarcastic meaning. PMID- 30282527 TI - Different Vascular Responses to a Bare Nitinol Stent in Porcine Femoral and Femoropopliteal Arteries. AB - Nitinol stents are widely used for the treatment of peripheral arterial diseases in lower extremity arteries and have shown different clinical outcomes depending on implanted arterial segments. We aimed to compare histopathological responses to nitinol stents in femoral artery (FA) with those in femoropopliteal artery (FPA), which is markedly bended during knee flexion. A single nitinol stent was implanted in FA and FPA of 21 domestic swine. The stented vessels were angiographically assessed and then harvested for histopathology at 1 and 3 months after implantation. Angiographic late lumen loss was significantly greater in FPA than in FA at 3 months. Neointimal area decreased in FA and increased in FPA from 1 to 3 months. Compared with FA, peri-strut area of FPA showed more pronounced hemorrhage and fibrin deposition at 1 month and angiogenesis and inflammation at 1 and 3 months. Injury to internal elastic lamina or media was minimal in both FA and FPA at both time points. In conclusion, vascular responses to nitinol stents were different between FA and FPA with respect to time course of neointimal formation and progress of healing, suggesting that repetitive interaction between stent and vessel wall during dynamic vessel motion affected vascular responses. PMID- 30282528 TI - Exercise, diet, and the reinforcing value of food in an animal model of anorexia nervosa. AB - Activity-based anorexia (ABA) develops when laboratory rats are subjected to a single meal per day and have access to an activity wheel for the remaining time. Here, we studied the contribution of exercise and diet to the reinforcing value of food during ABA development. Three groups of eight adult male Wistar rats were used: an ABA group with 21.5 hr (then 22 hr) of wheel access and 1 hr (then 30 min) of food access, a control group with the same time exposure to food but without exercise, and a yoked group to the ABA in terms of weight loss. Rats were daily tested on a progressive-ratio schedule to measure their motivation for food. ABA rats gradually reduced their body weight more than the food control group. Animals steadily increased their breaking points in parallel to losses in body weight, but no significant differences were found between groups. Adult rats can develop ABA, but their loss in weight neither resulted in a decrease of food intake nor in the motivation to obtain it. PMID- 30282529 TI - Top-down attentional factors modulate action priming in reach-to-grasp action. AB - Previous studies report that viewing exaggerated, high-lifting reaches (versus direct reaches) primes higher vertical deviation in wrist trajectory in the observer's subsequent reaches (trajectory priming), but it is unclear to what extent this effect depends upon task instructions relevant to top-down attention. In two experiments, participants were instructed to gaze at a dot presented on a large monitor for a colour-change go signal that cued them to execute a direct reach to a target. In the background, the monitor also displayed life-sized films of a human model. The films were of the model either remaining still or reaching to grasp a target with either a direct trajectory or an exaggerated, high-lifting trajectory. When the dot traced the human model's wrist throughout her movement, a robust trajectory priming effect emerged. When the dot remained stationary in a central location but the human model reached in the background, the human model's trajectory did not alter the participants' trajectories. Finally, when the dot traced exaggerated and direct trajectories and the human model remained stationary, the dot's movement produced an attenuated, non-significant trajectory priming effect. These findings show that top-down attentional factors modulate trajectory priming. In addition, a moving non-human stimulus does not produce the same degree of action priming when contextual factors make salient its independence of human agency and/or intention. PMID- 30282530 TI - Proceedings of the 2018 National Toxicology Program Satellite Symposium. AB - The 2018 annual National Toxicology Program Satellite Symposium, entitled "Pathology Potpourri," was held in Indianapolis, Indiana, at the Society of Toxicologic Pathology's 37th annual meeting. The goal of this symposium was to present and discuss challenging diagnostic pathology and/or nomenclature issues. This article presents summaries of the speakers' talks along with select images that were used by the audience for voting and discussion. Various lesions and other topics covered during the symposium included seminiferous tubule dysgenesis in rats, ameloblast and odontoblast degeneration/necrosis in a Sprague Dawley rat, intestinal leiomyositis in a beagle dog, gallbladder mucinous hyperplasia, focus of hepatocellular alteration and bile duct alteration in otters, renal tubule cytoplasmic vacuolation with basophilic granules in mice treated swith antisense oligonucleotide therapy, a uterine choriocarcinoma in a rhesus macaque, and rete ovarii proliferative ovarian lesions in various aged rat strains. One particularly provocative lesion was a malignant neoplastic proliferation in the renal pelvic region of a cynomolgus macaque from a 21-day study. Additional challenging lesions included thyroid proliferative lesions in zebra fish and gross findings in fish larvae during routine chemical screening. The Rabbit and Minipig International Harmonization of Nomenclature and Diagnostic Criteria Organ Working Groups also presented a series of challenging lesions. PMID- 30282531 TI - Endovascular treatment of proximal para-anastomotic aneurysms after previous surgical repair of infrarenal aortic aneurysms by the chimney technique. AB - Objectives To evaluate the use of chimney grafts in the treatment of para anastomotic aneurysms after previous abdominal aortic aneurysms open repair with short neck. Methods A retrospective analysis of prospectively collected data of consecutive patients who underwent endovascular repair for proximal aortic para anastomotic aneurysms following previous open repair for infrarenal abdominal aortic aneurysms was performed. All included patients had a short infrarenal aortic neck (<10 mm) excluding standard endovascular aortic repair. Five patients were symptomatic at the admission needed urgent treatment. Results Twelve patients with para-anastomotic aneurysms underwent placement of chimney grafts. The median time between the original operations to redo endovascular procedure was 11 years (interquartile range, 9.5 years). The mean infrarenal length was 4.3 mm (1-9 mm). A total of 28 chimneys grafts were deployed for the 12 patients. The technical success rate was 91.7%. At a median radiologic follow-up of 16 months (2.0-29.4, 95% confidence interval), one patient died, while two late endoleaks and two reinterventions at one and three years for type Ia endoleak were performed by proximal extension and triple chimney graft placement. Conclusion The results of the present study show that ch-endovascular aortic repair is a safe technique for patients who suffered from proximal para-anastomotic aneurysms and having short neck unsuitable for standard endovascular repair. Longer follow up warranted to evaluate the durability of ch-endovascular aortic repair for this specific indication. PMID- 30282532 TI - Triangular Fibrocartilage Complex Repair and Ulna Variance: A Systematic Review. AB - BACKGROUND: This purpose of the study was to conduct a systematic review of available literature regarding the association between ulnar variance and outcomes after repair of peripheral traumatic tears of the triangular fibrocartilage complex (TFCC). METHODS: A systematic literature search of the medical literature about peripheral tears of the TFCC was performed. We selected seven studies comparing clinical outcome and ulnar variance in patients with peripheral TFCC tears. We evaluated quality of the articles using both the Structured Effectiveness Quality Evaluation Scale (SEQES) and Sackett's Level of Evidence (LOE). The outcomes were objective or self-assessment scoring systems for the function of the hand, wrist, or upper extremity. RESULTS: Seven articles were evaluated. The SEQES scores varied from 19 to 28, with a mean of 23. Five studies reported no association between ulnar variance and clinical outcome, and 2 studies reported an association. The studies reporting no association either excluded or did not mention the cases of unstable distal radioulnar joint (DRUJ). CONCLUSIONS: This systematic review did not demonstrate strong evidence regarding the association between ulnar variance and outcomes after TFCC repair. As most of the studies did not distinguish between capsular and foveal tears which can affect DRUJ stability, further studies looking at this point are necessary to determine whether ulnar shortening osteotomy has an added value for better outcomes after TFCC repair. PMID- 30282533 TI - Continuous Peripheral Nerve Blocks for Early Active Mobilization after Hand Surgery: Four Case Reports. AB - Early active mobilization after hand surgery is extremely important for preventing scar tissue and adhesion. We examined four patients for whom continuous peripheral nerve blocks (CPNB) were used during and after hand surgery. This method was used for three median nerves and one ulnar nerve. A 2-cm incision was made at distal one-third of the forearm with local analgesia. The catheter tip was placed in the distal one-fourth of the forearm, and the hand surgery was begun. Early active mobilization and the self-rehabilitation exercise started immediately after the operation. The VAS scores during exercise were 0-2 (mean: 1.3); pain was controlled sufficiently. Regarding ROM, excellent results were obtained for tenolysis, with good results for arthrolysis. No infection or postoperative nerve compression was found. This method, using CPNB with a portable infusion pump, is effective and safe for use at home for postoperative pain control. PMID- 30282534 TI - Novel Unidirectional Porous beta-Tricalcium Phosphate Used as a Bone Substitute after Excision of Benign Bone Tumors of the Hand: A Case Series. AB - Unidirectional porous beta-tricalcium phosphate (UDPTCP; Affinos(r), Kuraray, Tokyo, Japan) has been in clinical use since 2015. Animal studies have confirmed the excellent potential of UDPTCP with regard to bone formation and material absorption. We present the first three clinical cases using UDPTCP as a bone substitute after curettage of benign bone tumors of the hand. All three patients were males, 29-, 30- and 81-years-old, two having a diagnosis of enchondroma and the other, a bone ganglion, with a pathological fracture identified in one case. Over a mean follow-up of 10 months, all patients achieved satisfactory clinical result, with no adverse events of UDPTCP noted. Radiographic evidence of good bone formation and material absorption was observable over the postoperative course. UDPTCP provided satisfactory clinical results, with good biocompatibility and fast resorption characteristics. Therefore, UDPTCP could provide a safe and reliable filling substitute for bone defects following curettage of small bone tumors. PMID- 30282535 TI - Ulnar Subluxation of the Extensor Pollicis Longus Tendon as a Cause of Congenital Clasped Thumb: A Case Report. AB - A 15-year-old male patient presented with difficulty extending his right thumb due to subluxation of the extensor pollicis longus (EPL) tendon. Physical examination showed that active motion of the thumb's metacarpophalangeal (MP) joint was 76 degrees in flexion and -58 degrees in extension. During active extension, the EPL tendon shifted onto the ulnar aspect of the MP joint, and the extensor pollicis brevis (EPB) tendon shifted onto the central dorsal course of the MP joint. After repositioning by adducting the thumb into the palm to extend the MP joint (dynamic tenodesis effect), active extension of the MP joint increased to -12 degrees . Corrective surgery was performed under local anesthesia and radial sensory nerve block. Following plication of the attenuated dorsal capsule and sagittal band between the EPB and EPL, we confirmed that the patient could flex and extend the thumb smoothly. One year postoperatively, the extension deficit of the MP joint had not recurred. PMID- 30282536 TI - A Well-Differentiated Liposarcoma in the Digit: A Case Report of the 5-Year Post Surgical Follow-Up. AB - A liposarcoma is extremely rare in the digits. A 73-year-old woman was diagnosed with a lipoma in her middle finger 10 years ago. As this tumor increased in size and presented with imaging findings that were atypical of lipomas, careful marginal resection biopsy outside the pseudo-capsule was performed, and the tumor was diagnosed as a well-differentiated liposarcoma. At the 5-year follow-up, the patient showed no evidence of local recurrence or metastasis, with no loss of hand function. The findings from this case suggest that even for a lipomatous tumor in the digits, further imaging examination and resection biopsy should be considered if the tumor presents with features that are atypical of lipomas. PMID- 30282537 TI - Dorsal Capsular Defect and Synovial Fistula to the Fourth Extensor Compartment: A Late Complication after Arthroscopic Dorsal Wrist Ganglionectomy. AB - Arthroscopic dorsal wrist ganglionectomy is demonstrably a safe procedure with recurrence rates comparable to open surgery. We present a patient with wrist pain following arthroscopic ganglion excision. MRI and arthroscopic findings showed a large dorsal capsular defect, synovial fistula to the fourth extensor compartment, and dorsal radiocarpal ligament resection. Ligament reconstruction and capsular imbrication resolved her symptoms. We postulate that this complication resulted from a large capsular resection. Because we feel that it can be difficult to judge the size of the debridement through an arthroscope, the need for adequate capsular resection in dorsal wrist ganglionectomy needs to be balanced by consideration of potential complications from more aggressive capsular debridement, and thus we feel that capsular resection should be limited to no more than 1 cm2. PMID- 30282538 TI - The Effect of Distal Phalanx Bony Dimensions in Suture Anchor Fixations of Tendon Avulsion. AB - BACKGROUND: The terminal phalanx of the fingers carries the attachment of the Flexor Digitorum Profundus (FDP) on the volar surface and the extensor on the dorsal surface. Avulsion of these tendons has traditionally been repaired with pull-through sutures. Recently, bone anchor sutures have been found to be of comparable biomechanical strength but with the added advantage of technical ease and fewer complications. However, the dimensions of the bone, at the site of insertion of the anchors, have never been studied. METHODS: Following some cases of penetration of the dorsal cortex by the anchors, we measured the antero posterior dimensions of the terminal phalanx in 251 digits from plain radiographs and compared these with the dimensions of the commonly used bone anchors. We also compared male and female digits. RESULTS: The anchors were oversized in 76% of index, 78% of ring and 100% of little fingers in the female population and in 49%, 44% and 97% of index, ring and little fingers respectively in the male population. CONCLUSIONS: This analysis of bone dimensions can be a useful guide to surgeons in choosing the appropriate implant for flexor tendon avulsions. PMID- 30282539 TI - Axial Rotation Test for Trapeziometacarpal Joint Hypermobility in the Normal Population. AB - BACKGROUND: The objective was to quantify joint laxity in healthy volunteers by measuring the passive axial rotation of the trapeziometacarpal joint using the axial rotation test. METHODS: Eighty volunteers (34 men and 46 women) were subjected to the axial rotation shear test and the degree of total rotational motion (TRM) was assessed. Volunteers were divided into Group I with a range of 18-50 years old and Group II for 51 years and older. Statistical analysis was performed. RESULTS: The average TRM in Group I was 32.3 mm for women, and 27.4 mm, for men (p = 0.04). The average TRM in women of Groups I and II, was 32.3 and 21.6 mm respectively, (p < 0.001). The average TRM in men of Groups I and II, was 27.4 and 19.4 mm (p < 0.001). In Group II the average TRM of women was 21.6 mm, and for men was 19.4 mm, which was not significantly different. CONCLUSIONS: Young women have greater degree of rotational laxity in the TM joint compared to men of the same age group and to older women. The axial rotation test can quantify the degree of rotational laxity of the TM joint. PMID- 30282540 TI - Establishing an Efficient Care Paradigm for Trigger Finger. AB - BACKGROUND: To identify the time course for efficacy of corticosteroid injections in the treatment of trigger finger. METHODS: A prospective single-center observational study was conducted, consisting of 38 patients with 41 trigger digits that were injected. Enrolled patients completed an initial Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire to determine the severity of their symptoms. Following the injection, patients were contacted at scheduled time points for up to 12 weeks to determine if, and when, objective resolution of symptoms occurred. Patients who received additional treatment, such as a second injection or surgery, and those who did not have objective relief of symptoms by 12 weeks were classified as failed. Upon symptom resolution or injection failure, patients were given a DASH exit questionnaire. RESULTS: 30 of 41 injected trigger digits resolved and 11 failed treatment with a single corticosteroid injection. The latest that any study participant experienced resolution of symptoms was 69 days. At 38 days, the rate of resolution of the study population slowed significantly. CONCLUSIONS: Although symptomatic resolution of trigger finger from a single corticosteroid injection can occur early on, a follow-up of 4 weeks (28 days) does not allow enough time for symptom resolution. The earliest a surgeon and patient should consider a secondary treatment is at 38 days. After 69 days without resolution, both surgeon and patient can be confident that further treatment is needed. PMID- 30282541 TI - The Austrian Flag - Severe Carpal Tunnel Syndrome: A Case Report. AB - In severe carpal tunnel syndrome a continuum of neural changes takes place depending on the degree and duration of the compression, beginning with breakdown of the blood-nerve barrier, followed by endoneurial oedema and, subsequently, perineurial thickening and ischemia. Persisting chronic compression will eventually result in axonal degeneration. We report a case of longstanding carpal tunnel syndrome with amyloid deposits and the unusual intraoperative 'Austrian flag' sign. PMID- 30282542 TI - Is Pseudomeningocele an Absolute Sign of Root Avulsion Brachial Plexus Injury? AB - BACKGROUND: The finding of pseudomeningocele from cervical myelogram is widely accepted as a pathognomonic sign for diagnosing root avulsion in brachial plexus injury. In general, motor power in this setting should be absent. However, in clinical practice, we observed that motor power in some patients was still preserved. The objective of this study is to evaluate the accuracy of pseudomeningocele from cervical myelogram for predicting root avulsion in brachial plexus injury. METHODS: We retrospectively reviewed 201 patients with brachial plexus injury from 2007-2011. Four patients were excluded due to open wound injury. Motor power of the key muscle of each nerve root was evaluated by skilled hand surgeons. All cervical myelogram was interpreted by radiologists. Sensitivities, specificities, positive predictive values and negative predictive values were calculated with 95% confidence interval. RESULTS: Thirty and 29% of pseudomeningocele occurred at C7 and C8 level, respectively. The sensitivity of pseudomeningocele of each root from C5 to T1 was low (range, 10-62%). The specificity was high only at C5 (91%) and T1 (96.2%). Over 20% of patients with pseudomeningocele at C6-8 levels had some motor function. The initial muscle power of these patients was M1 or M2 and 70% of them recovered to at least M3 at the final follow-up. CONCLUSIONS: Pseudomeningocele is not an absolute sign for diagnosing of root avulsion in brachial plexus injury due to its high false positive rate when compared with preoperative motor function of each root. Careful examination of the key muscle of each root is extremely crucial to prevent unnecessary operation on that cervical nerve root. PMID- 30282544 TI - Motec Wrist Arthroplasty: 4 Years of Promising Results. AB - BACKGROUND: The Motec cementless modular metal-on-metal ball-and-socket wrist arthroplasty is an implant with promising intermediate results. An alternative to primary wrist fusion, total wrist arthroplasty is an option for active patients, who wish to retain their wrist function. It is indicated in cases of degenerative osteoarthritis, post-traumatic arthritis and rheumatoid (inflammatory) arthritis. METHODS: A prospective review of patient demographics, pre and post-operative Disabilities of the Arm Shoulder and Hand (DASH), MAYO scores, range of movements and grip strengths. All complications in follow up were recorded across the 4 year period. RESULTS: 25 implants on 23 patients over 5.5 years, mean age 61; 8 females and 15 male. 10 patients with SLAC, 3 SNAC, 5 inflammatory and 7 patients with generalized osteoarthritis. The patients showed significant improvements of MAYO and DASH scores post-operatively, as well as the flexion/extension arc and grip strengths. There was just one case of implant loosening- the radial screw after a wound infection, which was revised with a longer screw. Two implants were converted to Motec fusion due to pain. One implant was dislocated and relocated. The remaining patients have had good wrist function. Only 6 patients were unable to return to work. CONCLUSIONS: Similar to published studies, this series shows the Motec implant to be a good motion preserving alternative to total wrist fusion. PMID- 30282543 TI - Vacuum-Assisted Closure (VAC) Using Multiple Foam Pieces for Hidden Space Drainage through Less Exposure in Musculoskeletal Infections. AB - BACKGROUND: Purulent musculoskeletal infections often require surgical debridement and drainage. However, when the infection is extensive or involving multiple layers of tissues, maintaining drainage of the involved spaces can be difficult, even with the application of vacuum-assisted closure (VAC) therapy. Wide exposure and aggressive debridement is often required for such cases, which in turn may complicate wound coverage. METHODS: A retrospective review was performed for 16 patients with musculoskeletal infections treated surgically. The diagnosis for the patients consisted of necrotizing fasciitis, large soft tissue abscess, peri-hardware abscess, infected compartment syndrome, emphysematous osteomyelitis, and gas gangrene of diabetic foot. We minimized the incision and resection for debridement and drainage, and instead we placed multiple foam pieces between the tissues involved with VAC, to maintain drainage of the hidden spaces with negative pressure. RESULTS: Infection was successfully controlled in all cases. The mean duration of VAC treatment was 16.1 days (range, 5-36) and the mean number of VAC changes was 5.1 (range, 1-13). Primary wound closure was achieved in 11 cases, while skin grafts were used to cover the remaining five cases, which consisted of necrotizing fasciitis, infected compartment syndrome, and diabetic foot gas gangrene. No complications specifically associated with VAC therapy were observed. CONCLUSIONS: VAC using multiple foam pieces for hidden space drainage appears to be effective for infection control. It is helpful for minimizing exposure and resection for drainage and debridement, although subsequent reduction of the necessity or the level of wound coverage should further be investigated. PMID- 30282546 TI - Forearm Compartment Syndrome Concomitant with Pseudoaneurysm of the Anterior Interosseous Artery after Minor Penetrating Injury. AB - A 16-year-old man sustained a minor penetrating injury to his forearm, resulting in pseudoaneurysm formation that caused acute compartment syndrome with muscle contracture. Surgical treatment, including fasciotomy, evacuation of the hematoma and aneurysmectomy, followed by intensive hand therapy provided a successful outcome. Traumatic pseudoaneurysm after penetrating injury is a rare cause of acute forearm compartment syndrome. Although minor penetrating injuries tend to be underestimated, this type of injury can cause subsequent serious pathological conditions. PMID- 30282545 TI - Fixed Anterior Position of Ulnar Nerve around Medial Condyle of Elbow with Bony Mass Causing Cubital Tunnel Syndrome. AB - A 20-year-old male has presented with mild numbness and tingling sensation at 4, 5th finger of his left hand. Simple radiograph and MRI images revealed bony mass at medial joint space of ulno-humeral joint. After surgical exploration, we found that there were two cause of ulnar nerve irritation symptom. Fixed ulnar nerve position at anterior aspect to medial condyle with deficiency of nerve gliding was one cause, and friction irritation around bony mass was another. It is rarely reported that ulnar nerve always travels to the anterior side of the medial condyle of the elbow, and there are no cases involving skeletal variation. In this case, the ulnar nerve may be penetrated while forming an anterior medial portal around elbow joint. It is important to know the path of the ulnar nerves very carefully through imaging and physical examination when there is a bony variant in the elbow joint. PMID- 30282547 TI - Collagenase Clostridium Histolyticum Injection with Precise Needle Length Adjusted by Silicone Tube Interposition for Dupuytren Contracture. AB - We describe our injection method for Collagenase Clostridium Histolyticum using a medical silicone tube after determining the optimal depth by ultrasonography. This procedure adjusts the exposed needle length to the planned injection depth by placing a sterilized silicone tube over the needle. The restricted depth provides not only precise injection into the middle of the cords but also avoids needle tip migration through the cord and into the vital structures, which prevents possible complications. This method is safe and simple. PMID- 30282548 TI - Repair Technique Using a Combination of Suture Anchor and Miniscrew in Flexor Digitorum Profundus Bony Avulsion Fracture with Bone Fragment in Zone 1. AB - Avulsion fracture of the volar base of the distal phalanx is a rare injury. Zone 1 flexor tendon injuries can be treated with either internal or external fixation techniques. Pull-out suture repairs are often used for FDP tendon avulsion injuries. However, the pull out suture technique is associated with a number of well documented complications including nail bed injury and pressure necrosis. Despite the variety of techniques available for the repair of acute distal zone 1 flexor tendon injuries, no one technique has proven to be superior to all others. We address our experience with treatment of FDP avulsion injuries using suture anchor and miniscrew. Our technique supplements the suture anchor technique, which often causes a lack of strength, with an additional miniscrew. We introduce two cases of combined method using both suture anchor and miniscrew for treatment of FDP avulsion injuries. PMID- 30282549 TI - Venous Thromboembolism in Upper Extremity Fractures. AB - BACKGROUND: Venous thromboembolism (VTE) has been studied in lower extremity fractures but little is known of its relation with upper extremity (UE) fractures. As an often overlooked but serious complication, VTE may compromise patient outcomes. METHODS: Using data on inpatients (aged >= 18 years) at a level I trauma center and patients in the National Surgical Quality Improvement Program database who sustained UE fractures (clavicle, humerus, or radius/ulna) and VTE in the same hospitalization between 2007 and 2014, the authors analyzed data on demographic characteristics, fracture type, VTE location (pulmonary embolism, lower extremity, or UE), VTE onset, polytrauma, operative or nonoperative management, comorbidities, and mortality. RESULTS: Of 1984 inpatients with UE fractures at 1 instution, 9 experienced VTE on admission, and 17 (15 received thromboprophylaxis) experienced VTE during hospitalization, for an overall VTE rate of 1.3%. VTE occurred most often in patients with fractures of the proximal humerus (3.0%) followed by the clavicle (2.0%), midshaft humerus (1.9%), distal radius/ulna (0.95%), and distal humerus/elbow (0.36%) (p = 0.0035). There were no significant trends in the incidence of PE (p = 0.33) over the study period, but there was a sharp rise since 2011. In the national database, 42 of 11570 (0.36%) patients with UE fracture had VTE, with incidence by fracture location ranging from 0.14% (radius/ulna) to 0.98% (proximal humerus) (p = 0.00001). Predictors were chronic steroid use (odds ratio [OR] = 6.22, p = .030), inpatient status (OR = 4.09, p = .002), and totally disabled functional status (OR = 3.31, p = .021). CONCLUSIONS: VTE incidence was highest following proximal humerus or clavicle fractures and are rarely associated with radius/ulna fractures. There may have been a rise in the incidence of PE since 2007, warranting further investigation. PMID- 30282550 TI - Clinical Examination of the Extensor Pollicis Brevis: Anatomical Study and Description of a Novel Clinical Sign. AB - BACKGROUND: The Extensor Pollicis Brevis (EPB) is an extrinsic thumb muscle whose main function is extension of the first metacarpophalangeal joint (MCPJ). It is subject to significant anatomical variation and may be absent, vestigial or have an anomalous distal attachment. Clinical examination of EPB is notoriously difficult and no reliable test has yet been described. We propose a novel test for the accurate examination of EPB. We sought to clarify the anatomical variations of EPB and to validate our clinical test using human cadaveric anatomical tests. METHODS: A structured literature review of all human cadaveric anatomical studies describing the attachments of EPB was performed using MEDLINE and Embase with the key words "Extensor Pollicis Brevis". A cadaveric anatomical study was performed using 18 unembalmed upper limbs. Positive and negative tests were simulated by manipulating the tendons of EPB, Extensor Pollicis Longus (EPL) and Flexor Pollicis Longus (FPL). Changes in tendon tension and joint position were measured and recorded. The EPB anatomy was then determined by dissection. RESULTS: Anatomical variations were present in the majority of wrists, with only 35% of EPB tendons having a distal attachment to the proximal phalanx alone. EPB was absent in 5% of specimens. There was a significant difference between the change in MCPJ position between a positive (36 degrees; 95% CI 25 to 47 degrees) and negative (19 degrees; 95% CI 14 to 25 degrees) clinical test (p = 0.002). CONCLUSIONS: The functional importance of EPB depends on its congenital architecture in addition to the functional demands of the patient. We report a novel clinical test which is effective in demonstrating the integrity of the EPB. A positive test result is observed when a change in MCPJ position that occurs while the interphalangeal joint is brought into flexion from full thumb extension is 25 degrees or more. PMID- 30282551 TI - Cost Comparison of Collagenase Clostridium Histolyticum and Fasciectomy for Treatment of Dupuytren's Contracture in the Australian Health System. AB - BACKGROUND: Dupuytren's disease results in contracted cords in the hand that lead to deformity and disability. Current treatment options include fasciectomy and an injectable, collagenase clostridium histolyticum. No cost comparison studies have been published within the Australian health care environment. METHODS: A retrospective review of all patients treated for Dupuytren's disease in a major teaching hospital was undertaken to compare the costs of treatment by fasciectomy or collagenase injection. RESULTS: Eighteen patients underwent fasciectomy and 21 collagenase clostridium histolyticum injections were performed during the study period and were eligible for inclusion under the review criteria. Of the 39 patients, 36 were male and 3 were female with an average age 66.4 years (50-85). Twenty-five digits were treated by fasciectomy in 18 patients, and 23 digits were treated by collagenase in 21 patients. The fasciectomy group attended an average 9.2 visits (5-22), incurring an average costing of US$5738.12 per patient ($3181.18-$9618.10). The collagenase group attended an average 3.8 visits (3-8), incurring an average costing of US$2076.83 per patient ($1842.24-$3929.57). CONCLUSIONS: Collagenase treatment of Dupuytren's contracture represents a significant reduction in cost relative to fasciectomy, with 64% savings, length of follow up and number of visits. This is a similar finding to studies in other countries. PMID- 30282552 TI - Anatomical Basis for Arthroscopy of the Proximal Interphalangeal Joints. AB - BACKGROUND: Arthroscopy is a widely used minimally invasive technique. Nevertheless, no report describes the arthroscopic anatomy of the proximal interphalangeal (PIP) joint for portal creation. To facilitate arthroscopy, this study elucidated the anatomy of the lateral bands of the extensor mechanism and collateral ligaments of PIP joints. METHODS: A total of 39 fingers from the right hands of 10 cadavers (4 males, 6 females) were evaluated in this study. We defined the extension line from the proximal interphalangeal volar crease as the C-line. We also defined an imaginary line along the distal edge of the proximal phalanx, which is parallel to the C-line, as the J-line. The distance between J line and C-line was measured. On the C-line and J-line, we measured the following: from the dorsal skin to the lateral edge of the lateral band (LB), the dorsal edge of the collateral ligament (CL) and from the lateral band and the collateral ligament (D), the width of the finger (W). The finger half-width (M) was measured on the J-line. Comparison between the digits and comparison between radial and ulnar distance were measured and statistical analysis was performed. RESULTS: All PIP joint spaces were distal from the C-line, except for one ring finger. The average distances between the J-line and C-line were 1.8-3.2 mm. On the C-line, only 11 cases (14.1%) showed an interval between the lateral bands and the collateral ligaments, but, on the J-line 72, cases (92.3%) had such an interval. The interval was located 1.6-2.9 mm in a dorsal direction from the midlateral on the J-line. CONCLUSIONS: Portal creation at the J-line is safer than at the C-line. This study revealed that safe portals for arthroscopy of the PIP joint are 2 mm dorsal to the midlateral line of the finger on the J-line.

AB - BACKGROUND: This study aimed to investigate whether the distance between the radial nerve and rotational center of the elbow joint when observing from the lateral surface of the humerus changes according to passive elbow joint flexion for safe external fixation with a hinged fixator of the elbow joint. METHODS: Twenty fresh-frozen cadaveric arms were dissected. The points where the radial nerve crosses over the posterior aspect of the humerus, crosses through the lateral center, and crosses over the anterior aspect of the humerus were defined in the lateral view of the elbow joint, using fluoroscopy, as R1, R2, and R3, respectively. The distances between the rotational center and each point on the radial nerve were measured when the flexion angle of the elbow joint was 10 degrees , 50 degrees , 90 degrees , and 130 degrees . RESULTS: The distances between the rotational center and R1, R2, and R3 were 118 mm, 94 mm, and 65 mm, respectively, when the flexion angle was 10 degrees ; 112 mm, 93 mm, and 74 mm, respectively, for 50 degrees ; 108 mm, 93 mm, and 77 mm, respectively, for 90 degrees ; and 103 mm, 94 mm, and 83 mm, respectively, for 130 degrees . The distance between the rotational center and R2 was constant regardless of the flexion angle. With elbow joint extension, the distances between R1 and R3 increased; the safe zone, a region where the radial nerve would not be located on the humerus, was the smallest in extension. When the elbow joint was flexed, the distances between R1 and R3 decreased; the safe zone was the largest in flexion. CONCLUSIONS: This study showed that the radial nerve location on the humerus varied based on the flexion angle of the elbow joint; the safe zone may change. A half-pin can be likely inserted safely, avoiding the elbow joint extension position. PMID- 30282554 TI - A Functional Angle of Up to 35 degrees at the Distal Interphalangeal Joint Can Be Achieved with Headless Compression Screw Fusion. AB - BACKGROUND: Arthrodesis of the distal interphalangeal (DIP) joint reliably improves symptomatic arthritis. A range of successful surgical techniques including tension band wiring, plate fixation and headless compression screws have been described and produce stable painless unions. For best functional outcome, the fusion angle should be between 10 and 61 degrees. In the past, it has been difficult to achieve more than 10 degrees of flexion with a headless compression screw. Higher fusion angles have been reported using tension band wiring techniques. However, metalwork prominence is a common problem and may require revision surgery to rectify this. Headless compression screws are reported to cause iatrogenic fractures due to the size of the screw relative to the small diameter of the phalanx. This case series achieves an angle of up to 35 degrees with a good functional outcome. METHODS: Open fusion of the DIP joint with a headless cannulated compression screw, of 2.2 mm in diameter, was undertaken in fifteen digits. Patients received standard departmental follow up to radiographic union. Patients self-reported function using the Michigan Hand Questionnaire post operatively. The fusion angles achieved were assessed on postoperative radiographs. RESULTS: All patients went on to a stable union without any patients requiring revision surgery as a result of fracture or protrusion of metalwork. Complications were observed in two patients which included one superficial infection (n = 1) and a discomfort requiring removal of metalwork (n = 1). Functional scores measured post operatively showed favourable outcomes. CONCLUSIONS: In this series, successful fusions of the DIP joints, at an angle up to 35 degrees were achieved using small diameter headless compression screws, which provided benefits including early mobilization and favourable functional outcome scores. PMID- 30282555 TI - Reliability and Concurrent Validity of the Ring Gauge Method and the Metacarpal Head Tape Measure Method of Measuring Hand Size. AB - BACKGROUND: There are several methods for measuring edema of the hand. While the volumetric techniques, finger circumference measurement, and figure-of-eight techniques have undergone extensive psychometric testing, alternative methods of measuring hand size, such as circumferential finger size determination using a ring gauge (ring gauge method; RGM) and tape measurement of hand girth taken along the distal palmar crease (metacarpal head tape measure method; MHTM), have not. This study's aim is to examine the reliability and validity of the RGM and the MHTM. METHODS: In this cross-sectional study, two examiners measured 22 hands in 22 patients with hand edema using the RGM and the MHTM 3 times each to determine intra- and inter-tester reliability. The validity of each method was established using the finger circumference measurement and figure-of-eight method, respectively. RESULTS: The intra-class correlation coefficient (ICC) obtained for intra-tester reliability was 0.99-0.98 for both methods. ICCs for inter-tester reliability were 0.97-0.98 for the RGM and 0.98 for the MHTM. Pearson product-moment correlation values between the RGM and finger circumference measurement were 0.92-0.96, while those between the MHTM and figure of-eight method were 0.84-0.90. CONCLUSIONS: The RGM and the MHTM are reliable and valid evaluation tools for the assessment of hand size. PMID- 30282556 TI - Midwest Nursing Research Society News.

PMID- 30282560 TI - The anti-thrombotic effects of vitamin D and their possible relationship with antiphospholipid syndrome. AB - The importance of the immunomodulatory effects of vitamin D has recently been associated with autoimmune and chronic inflammatory diseases. Vitamin D deficiency has been linked to the development of autoimmune conditions. Antiphospholipid syndrome is an autoimmune disease characterized by thrombotic events and obstetric complications in patients with antiphospholipid antibodies. Current data show that patients with antiphospholipid syndrome have a high prevalence of vitamin D deficiency even without classic risk factors. Several studies have suggested vitamin D may have anti-thrombotic functions. In antiphospholipid syndrome, low vitamin D serum levels have been associated with thrombotic manifestations, suggesting a possible protective role of vitamin D in antiphospholipid syndrome. This literature review presents current evidence on the haemostatic functions of vitamin D and their possible relationship with the clinical manifestations of antiphospholipid syndrome. PMID- 30282561 TI - The blood-brain barrier, TWEAK, and neuropsychiatric involvement in human systemic lupus erythematosus and primary Sjogren's syndrome. AB - OBJECTIVE: A prevailing hypothesis for neuropsychiatric involvement in systemic lupus erythematosus (SLE) and primary Sjogren's syndrome is that brain reactive autoantibodies enter the brain through a disrupted blood-brain barrier. Our aim was to investigate whether TNF-like weak inducer of apoptosis (TWEAK) plays a role in cerebral involvement in human SLE and primary Sjogren's syndrome, and whether an impaired blood-brain barrier is a prerequisite for neuropsychiatric manifestations. METHODS: TWEAK was measured in the cerebrospinal fluid and serum and compared with markers of blood-brain barrier permeability (Q-albumin and MRI contrast-enhanced lesions) and S100B, an astrocyte activation marker in 50 SLE and 52 primary Sjogren's syndrome patients. Furthermore, we estimated the general intrathecal B-cell activation (IgG index), measured anti-NR2 antibodies in cerebrospinal fluid, and explored whether these variables were associated with neuropsychiatric manifestations. RESULTS: No associations were found between TWEAK in the cerebrospinal fluid or serum and neuropsychiatric manifestations in SLE nor in primary Sjogren's syndrome patients. Furthermore, no associations were found between neuropsychiatric manifestations and indicators of blood-brain barrier integrity or astroglial activity. Anti-NR2 antibodies were associated with impaired visuospatial processing (odds ratio 4.9, P = 0.03) and motor functioning (odds ratio 6.0, P = 0.006). CONCLUSION: No clinical neuropsychiatric manifestations could be attributed to impaired integrity of the blood-brain barrier, or to TWEAK levels in cerebrospinal fluid or serum in either patient group. The TWEAK concentration was considerably higher in the cerebrospinal fluid than in blood, which indicates intrathecal production. We hypothesize that increased TWEAK and S100B result from immunological stress caused by brain reactive antibodies produced by brain residing immune cells. PMID- 30282562 TI - Systemic lupus erythematosus is a risk factor for cardiovascular disease: a nationwide, population-based study in Korea. AB - OBJECTIVE: To investigate the incidence and clinical significance of cardiovascular disease in systemic lupus erythematosus patients. METHODS: We included systemic lupus erythematosus patients ( n = 18,575) without previous cardiovascular disease and age- and sex-matched individuals without systemic lupus erythematosus (controls; n = 92,875) from the Korean National Health Insurance Service database (2008-2014). Both cohorts were followed up for incident cardiovascular disease and death until 2015. RESULTS: During follow up, myocardial infarction occurred in 203 systemic lupus erythematosus patients and 325 controls (incidence rate: 1.76 and 0.56 per 1000 person-years, respectively), stroke occurred in 289 patients and 403 controls (incidence rate: 2.51 and 0.70 per 1000 person-years, respectively), heart failure occurred in 358 patients and 354 controls (incidence rate 3.11 and 0.61 per 1000 person-years, respectively), and death occurred in 744 patients and 948 controls (incidence rate 6.54 and 1.64 per 1000 person-years, respectively). Patients with systemic lupus erythematosus had higher risks for myocardial infarction (hazard ratio: 2.74, 95% confidence interval: 2.28-3.37), stroke (hazard ratio: 3.31, 95% confidence interval: 2.84 3.86), heart failure (hazard ratio: 4.60, 95% confidence interval: 3.96-5.35), and cardiac death (hazard ratio: 3.98, 95% confidence interval: 3.61-4.39). CONCLUSIONS: Here, systemic lupus erythematosus was an independent risk factor for cardiovascular disease, thus cardiac assessment and management are critical in systemic lupus erythematosus patients. PMID- 30282563 TI - Stillbirth in Western Australia, 2005-2013: the influence of maternal migration and ethnic origin. AB - OBJECTIVE: To investigate prevalence rates and the risk of ante- and intrapartum stillbirth in Western Australia with respect to maternal country of birth and ethnic origin. DESIGN, SETTING AND PARTICIPANTS: Whole population retrospective cohort analysis of de-identified, linked routinely collected birth, perinatal and mortality data for all births to non-Indigenous women in WA during 2005-2013. MAIN OUTCOME MEASURES: Crude and adjusted odds ratios (aORs) with 95% confidence intervals were estimated by logistic regression and adjusted for confounding factors, for all stillbirths, antepartum stillbirths and intrapartum stillbirths, stratified by migrant status and ethnic background (white, Asian, Indian, African, Maori, other). RESULTS: Women born overseas were more likely to have a stillbirth than Australian-born women (aOR, 1.26; 95% CI, 1.09-1.37). There was no significant difference for any type of stillbirth between Australian-born women of white and non-white backgrounds, but non-white migrant women were more likely than white migrants to have a stillbirth (OR, 1.42; 95% CI, 1.19-1.70). Compared with Australian-born women, migrants of Indian (aOR, 1.71; 95% CI, 1.17 2.47), African (aOR, 2.12; 95% CI, 1.46-3.08), and "other" ethnic origins (aOR, 1.43; 95% CI, 1.06-1.93) were more likely to have antepartum stillbirths; women of African (aOR, 5.08; 95% CI, 3.14-8.22) and "other" (aOR, 1.86; 95% CI, 1.15 3.00) background were more likely to have an intrapartum stillbirth. CONCLUSIONS: Immigrants of African or Indian background appear to be at greater risk of ante- and intrapartum stillbirth in WA. Specific strategies are needed reduce the prevalence of stillbirth in these communities.

AB - OBJECTIVE: To evaluate whole-genome sequencing (WGS) as a molecular typing tool for MRSA outbreak investigation. DESIGN: Investigation of MRSA colonization/infection in a neonatal intensive care unit (NICU) over 3 years (2014-2017). SETTING: Single-center level IV NICU.PatientsNICU infants and healthcare workers (HCWs). METHODS: Infants were screened for MRSA using a swab of the anterior nares, axilla, and groin, initially by targeted (ring) screening, and later by universal weekly screening. Clinical cultures were collected as indicated. HCWs were screened once using swabs of the anterior nares. MRSA isolates were typed using WGS with core-genome multilocus sequence typing (cgMLST) analysis and by pulsed-field gel electrophoresis (PFGE). Colonized and infected infants and HCWs were decolonized. Control strategies included reinforcement of hand hygiene, use of contact precautions, cohorting, enhanced environmental cleaning, and remodeling of the NICU. RESULTS: We identified 64 MRSA-positive infants: 53 (83%) by screening and 11 (17%) by clinical cultures. Of 85 screened HCWs, 5 (6%) were MRSA positive. WGS of MRSA isolates identified 2 large clusters (WGS groups 1 and 2), 1 small cluster (WGS group 3), and 8 unrelated isolates. PFGE failed to distinguish WGS group 2 and 3 isolates. WGS groups 1 and 2 were codistributed over time. HCW MRSA isolates were primarily in WGS group 1. New infant MRSA cases declined after implementation of the control interventions. CONCLUSION: We identified 2 contemporaneous MRSA outbreaks alongside sporadic cases in a NICU. WGS was used to determine strain relatedness at a higher resolution than PFGE and was useful in guiding efforts to control MRSA transmission. PMID- 30282567 TI - Prevalence and predictors of malnutrition in elderly Chinese adults: results from the China Health and Retirement Longitudinal Study. AB - OBJECTIVE: China has the largest population of elderly citizens in the world, with 177 million adults aged 60 years or older. However, no national estimate of malnutrition in elderly Chinese adults exists. We estimated the prevalence and predictors of malnutrition in this population. DESIGN: Data from the second wave of the Chinese Health and Retirement Longitudinal Study (CHARLS) include interview and biomarker data for 6450 subjects aged 60 years or older from 448 different communities in twenty-eight provinces, allowing for nationally representative results. Malnutrition was identified based on the ESPEN (European Society of Parenteral and Enteral Nutrition and Metabolism) criteria. We used multivariable regression to investigate the predictors of malnutrition, including demographic factors, marital status, self-reported health status, self-reported standard of living, health insurance status and education. SETTING: China. SUBJECTS: Community-dwelling Chinese adults aged 60 years or older. RESULTS: The prevalence of malnutrition in elderly Chinese adults was 12.6 %. Malnutrition was most common among those who were older (OR=1.09; 95 % CI 1.07, 1.10), male (OR=1.41; 95 % CI 1.10, 1.79), lived in rural areas (v. urban: OR=0.75; 95 % CI 0.57, 1.00) or lacked health insurance (P<0.01). CONCLUSIONS: The burden of malnutrition on elderly Chinese adults is significant. Based on current population estimates, up to 20 million are malnourished. Malnutrition is strongly associated with demographic factors, shows a trend to association with health status and is not strongly associated with standard of living or education. A coordinated effort is needed to address malnutrition in this population. PMID- 30282568 TI - Automated Indices of Clustering and Switching of Semantic Verbal Fluency in Parkinson's Disease. AB - OBJECTIVES: Deficits in semantic verbal fluency (SVF) can stem from dysfunction of an executive control system and/or of semantic knowledge. Previous analyses of SVF responses were devised to characterize these two components including switching and mean cluster size (MCS) indices, but these rely on subjective experimenter-based assessment of the words' relatedness. To address this limitation, computational data-driven SVF indices have been developed. Our aim is to assess the validity and usefulness of these automated indices in the context of cognitive decline in Parkinson's disease (PD). METHODS: This is a retrospective study including 50 advanced PD patients with (n=28) or without (n=22) mild cognitive impairment (PD-MCI). We analyzed animal SVF outputs using an automated computational approach yielding switching, MCS, and cumulative relatedness (CuRel) indices. We compared these indices to the classic experimenter-based switching and MCS indices to assess concurrent validity, and against neuropsychological measures of executive functioning and semantic knowledge to assess construct validity. We also examined whether these indices were impaired and predicted PD-MCI. RESULTS: Automated switching indices, but not MCS or CuRel, showed evidence of concurrent and construct validity, and characterized individual difference in advanced PD. Automated switching indices also outperformed the experimenter-dependent index in predicting the presence of PD-MCI. CONCLUSION: Computational methods hold promise as fine-grained, unbiased indices reflecting the executive component of SVF, but none of the methods provided valid measures of semantic knowledge in PD. Our data also confirm that SVF are not adequate tests of semantic memory in patients with executive dysfunction such as PD. (JINS, 2018, 24, 1047-1056). PMID- 30282569 TI - Transdiagnostic dimensions of psychopathology at first episode psychosis: findings from the multinational EU-GEI study. AB - BACKGROUND: The value of the nosological distinction between non-affective and affective psychosis has frequently been challenged. We aimed to investigate the transdiagnostic dimensional structure and associated characteristics of psychopathology at First Episode Psychosis (FEP). Regardless of diagnostic categories, we expected that positive symptoms occurred more frequently in ethnic minority groups and in more densely populated environments, and that negative symptoms were associated with indices of neurodevelopmental impairment. METHOD: This study included 2182 FEP individuals recruited across six countries, as part of the EUropean network of national schizophrenia networks studying Gene Environment Interactions (EU-GEI) study. Symptom ratings were analysed using multidimensional item response modelling in Mplus to estimate five theory-based models of psychosis. We used multiple regression models to examine demographic and context factors associated with symptom dimensions. RESULTS: A bifactor model, composed of one general factor and five specific dimensions of positive, negative, disorganization, manic and depressive symptoms, best-represented associations among ratings of psychotic symptoms. Positive symptoms were more common in ethnic minority groups. Urbanicity was associated with a higher score on the general factor. Men presented with more negative and less depressive symptoms than women. Early age-at-first-contact with psychiatric services was associated with higher scores on negative, disorganized, and manic symptom dimensions. CONCLUSIONS: Our results suggest that the bifactor model of psychopathology holds across diagnostic categories of non-affective and affective psychosis at FEP, and demographic and context determinants map onto general and specific symptom dimensions. These findings have implications for tailoring symptom-specific treatments and inform research into the mood-psychosis spectrum. PMID- 30282571 TI - Influence of follicle size on bovine oocyte lipid composition, follicular metabolic and stress markers, embryo development and blastocyst lipid content. AB - This study assessed the lipid composition of oocytes from different follicle sizes and compared the expression of lipid-related genes and follicular fluid (FF) molecules between groups. We also investigated the functional consequences of differences on embryo development and blastocyst lipid deposits. Oocytes and FF were recovered from different follicle sizes. Oocytes from small (<=5 mm) and large (>=6mm) bovine follicles were used to produce Day 7 expanded blastocysts (Day7Ex) and blastocysts that only became expanded at Day 8 (Day8Ex) after insemination. Oocytes from >8 mm follicles had the highest lipid content. Few oocyte phospholipid variations were identified between groups. Very long chain fatty acid elongase 6 (ELOVL6) mRNA abundance was reduced in larger follicle derived oocytes compared with the <=2mm group. Increased levels of glucose, reactive oxygen species, glutathione and superoxide dismutase activity were also identified in FF from larger follicles. Large follicle-derived embryo development and lipid content of Day7Ex were greater than those derived from small follicles. Day8Ex had greater lipid deposition than Day7Ex. Oocytes and blastocysts exhibited follicle size-specific lipids. Large-follicle oocytes had increased lipid content and became Day7Ex with greater lipid deposition whereas delayed blastocoel expansion associated with a prolonged period of culture determined the lipid accumulation of Day8Ex. The FF microenvironment of large follicles seems to favour embryo development. PMID- 30282570 TI - Comparison of Aerosol- and Percutaneous-acquired Venezuelan Equine Encephalitis in Humans and Nonhuman Primates for Suitability in Predicting Clinical Efficacy under the Animal Rule. AB - Licensure of medical countermeasure vaccines to protect against aerosolized Venezuelan equine encephalitis virus (VEEV) requires the use of the Animal Rule to assess vaccine efficacy, because human studies are not feasible or ethical. We therefore performed a retrospective study of VEE cases that occurred in at-risk laboratory workers and support personnel during the United States Biowarfare Program (1943-1969) to better define percutaneous- and aerosol-acquired VEE in humans and to compare these results with those described for the NHP model (in which high-dose aerosol VEEV challenge led to more severe encephalitis than parenteral challenge). Record review and analysis of 17 aerosol- and 23 percutaneous-acquired human cases of VEE included incubation period, symptoms, physical examination findings, and markers of infection. Human VEE disease by both exposure routes presented as acute febrile illness, typically with fever, chills, headache, back pain, malaise, myalgia, anorexia, and nausea. Aerosol exposure more commonly led to upper respiratory tract-associated findings of sore throat (59% compared with 26%), pharyngeal erythema (76% compared with 52%), neck pain (29% compared with 4%), and cervical lymphadenopathy (29% compared with 4%). Other disease manifestations, including encephalitis, were similar between the 2 exposure groups. The increase in upper respiratory tract findings in aerosol acquired VEE in humans has not previously been reported but is supported by the mouse model, which showed nasal mucosal necrosis, necrotizing rhinitis, and an increase in upper respiratory tract viral burden associated with aerosol VEEV challenge. Fever, viremia, and lymphopenia were common markers of VEE disease in both humans and NHP, regardless of the exposure route. Taken collectively, our findings provide support for use of the nonlethal NHP model for advanced development of medical countermeasures against aerosol- or percutaneous-acquired VEE. PMID- 30282572 TI - Effects of ten-eleven translocation 1 (Tet1) on DNA methylation and gene expression in chicken primordial germ cells. AB - Ten-eleven translocation 1 (Tet1) is involved in DNA demethylation in primordial germ cells (PGCs); however, the precise regulatory mechanism remains unclear. In the present study the dynamics of 5-methylcytosine (5mC) and 5 hydroxymethylcytosine (5hmC) in developing PGCs and the role of Tet1 in PGC demethylation were analysed. Results show that 5mC levels dropped significantly after embryonic Day 4 (E4) and 5hmC levels increased reaching a peak at E5-E5.5. Interestingly, TET1 protein was highly expressed during E5 to E5.5, which showed a consistent trend with 5hmC. The expression of pluripotency-associated genes (Nanog, PouV and SRY-box 2 (Sox2)) and germ cell-specific genes (caveolin 1 (Cav1), piwi-like RNA-mediated gene silencing 1 (Piwi1) and deleted in azoospermia-like (Dazl)) was upregulated after E5, whereas the expression of genes from the DNA methyltransferase family was decreased. Moreover, the Dazl gene was highly methylated in early PGCs and then gradually hypomethylated. Knockdown of Tet1 showed impaired survival and proliferation of PGCs, as well as increased 5mC levels and reduced 5hmC levels. Further analysis showed that knockdown of Tet1 led to elevated DNA methylation levels of Dazl and downregulated gene expression including Dazl. Thus, this study reveals the dynamic epigenetic reprogramming of chicken PGCs in vivo and the molecular mechanism of Tet1 in regulating genomic DNA demethylation and hypomethylation of Dazl during PGC development. PMID- 30282574 TI - Biased Results Owing to Competing Interests? PMID- 30282573 TI - Medical Treatment of COPD. AB - BACKGROUND: Chronic obstructive pulmonary disease (COPD) is common around the world and carries a high morbidity and mortality. Symptom- and risk-oriented drug treatment is recommended, both in Germany and in other countries. It is not yet known to what extent the treatment that is actually delivered in Germany corresponds to the current recommendations in the guidelines. METHODS: As recommended by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) in 2017, 2281 patients of the national COPD cohort COSYCONET (COPD and Systemic Consequences-Comorbidities Network) were classified into Gold classes A-D on the basis of disease-specific manifestations and the frequency of exacerbations. Moreover, the regular use of medications was documented and categorized according to active substance groups. For all groups, the documented treatment that was actually given was compared to the recommended treatment. RESULTS: 67.6% of the patients received a combination of a long-acting anticholinergic drug (LAMA) and a long-acting beta-mimetic drug (LABA), while 65.8% received inhaled corticosteroids (ICS), 11.7% theophylline, and 12.6% oral corticosteroids (OCS). Despite recommendations to the contrary, 66% of the patients in Groups A and B (low exacerbation rates) were treated with ICS; some of these patients carried an additional diagnosis of bronchial asthma. There was evidence of undertreatment mainly in groups C and D (high exacerbation rate), because many of the patients in these groups were not treated with LAMA or LAMA/LABA as recommended. CONCLUSION: The observed deviations from the recommended treatment, some of which were substantial, might lead to suboptimal treatment outcomes as well as to avoidable side effects of medication.

AB - BACKGROUND: Analyses of the urinary proteome have been proposed as a novel approach for early assessment of increased risk of renal- or cardiovascular disease. Here we investigate the potentials of various classifiers derived from urinary proteomics for prediction of renal and cardiovascular comorbidities in patients with type 2-diabetes. METHODS: The study was a post hoc analysis of the randomized controlled Steno-2 trial comparing intensified multifactorial intervention to conventional treatment of type 2-diabetes and microalbuminuria. 151 diabetic patients with persistent microalbuminuria were included in year 1995 and followed for up to 19 years. For renal outcomes, two classifiers (CKD273 and a novel, GFR-based classifier) and for cardiovascular outcomes, three classifiers (CAD238, ACSP and ACSP75) were applied. Renal endpoints were progression to macroalbuminuria, impaired renal function (GFR < 45 ml/min/1.73 m2) or progression to end stage renal disease (ESRD) or death. Cardiovascular endpoints were coronary artery disease and a composite endpoint of incident death of cardiovascular disease, myocardial infarction or revascularization, stroke, amputation or peripheral revascularization. RESULTS: CKD273 was not consistently associated with renal outcomes. The GFR-based classifier was associated with impaired renal function, but lost significance in extensively adjusted models. Both the ACSP75 and ACSP-scores, but not the CAD238-score were inversely associated (opposing the hypothesis) with cardiovascular endpoints. None of the classifiers improved prediction of any outcome on top of standard risk factors. CONCLUSIONS: Risk-scores based upon urinary proteomics did not improve prediction of renal and cardiovascular endpoints on top of standard risk factors such as age and GFR during long-term (19 years) follow up in patients with type 2-diabetes and microalbuminuria. PMID- 30282583 TI - The Diagnosis and Treatment of Anxiety Disorders. AB - BACKGROUND: Anxiety disorders are the most common type of mental illness in Europe, with a 12-month prevalence of 14% among persons aged 14 to 65. Their onset is usually in adolescence or early adulthood. The affected patients often develop further mental or somatic illnesses (sequential comorbidity). METHODS: This review is based on pertinent publications retrieved by a selective search in PubMed. RESULTS: The group of anxiety disorders includes generalized anxiety disorder (GAD), phobic disorders, panic disorders, and two disorders that are often restricted to childhood-separation anxiety and selective mutism. A comprehensive differential diag- nostic evaluation is essential, because anxiety can be a principal manifestation of other types of mental or somatic illness as well. Psychotherapy and treatment with psychoactive drugs are the therapeutic strategies of first choice. Of all types of psycho- therapy, cognitive behavioral therapy has the best documented efficacy. Modern antidepressants are the drugs of first choice for the treatment of panic disorders, agoraphobia, social phobia, and GAS; pregabalin is a further drug of first choice for GAS. CONCLUSION: In general, anxiety disorders can now be effectively treated. Patients should be informed of the therapeutic options and should be involved in treatment planning. Current research efforts are centered on individualized and therefore, it is hoped, even more effective treatment approaches than are available at present. PMID- 30282585 TI - The surgical choice for unilateral thyroid carcinoma in pediatrics: Lobectomy or total thyroidectomy? AB - BACKGROUND: Total thyroidectomy is no doubt the standard procedure for patients with bilateral thyroid carcinoma in pediatrics. However, for lesions confined in unilateral thyroid gland, lobectomy or radical total thyroidectomy is still controversial in pediatrics. METHODS: Thirty-five cases of pediatric thyroid carcinoma which were confirmed by pathology were retrospectively analyzed in our hospital from 2005 to 2016. In 13 cases of unilateral lesions, 6 received lobectomy, while others underwent total thyroidectomy. Recurrence and complications were compared between 2 groups. Also, there were 20 cases of primary total thyroidectomy and 4 cases of supplementary resection of the residual gland. The short-term complications were compared. RESULTS: There were no differences between groups of lobectomy and total thyroidectomy in size, extrathyroid extension, stage, cervical lymph nodes metastases, and distant metastases. They were the same in incidence of postoperative hypocalcemia, calcium supplement, recurrent laryngeal nerve damage, and recurrence rate and mortality, except that the length of stay in hospital was shorter in lobectomy group. Patients in supplementary resection were more likely to present the symptoms of postoperative hypocalcemia and hypokalemia, and it was difficult to identify the parathyroid gland during the operation by comparing with patients of primary total thyroidectomy. CONCLUSIONS: Thyroid carcinoma in pediatrics is inclined to be multifocal, and even in a single focus, the volume is large. Total thyroidectomy does not bring more complications. In contrast, the morbidity increases in staged resection. Endocrine hormone supplement can satisfy the need for growth and development. TYPE OF STUDY: Treatment study. LEVEL OF EVIDENCE: Level III.

AB - Standard musculoskeletal simulation tools now offer widespread access to internal loading conditions for use in improving rehabilitation concepts or training programmes. However, despite broad reliance on their outcome, the accuracy of such loading estimations, specifically in deep knee flexion, remains generally unknown. The aim of this study was to evaluate the error of tibio-femoral joint contact force (JCF) calculations using musculoskeletal simulation compared to in vivo measured JCFs in subjects with instrumented total knee endoprostheses during squat exercises. Using the early but common "Gait2392_simbody" (OpenSim) scaled musculoskeletal models, tibio-femoral JCFs were calculated in 6 subjects for 5 repetitions of squats. Tibio-femoral JCFs of 0.8-3.2 times bodyweight (BW) were measured. While the musculoskeletal simulations underestimated the measured knee JCFs at low flexion angles, an average error of less than 20% was achieved between approximately 25 degrees -60 degrees knee flexion. With an average error that behaved almost linearly with knee flexion angle, an overestimation of approximately 60% was observed at deep flexion (ca. 80 degrees ), with an absolute maximum error of ca. 1.9BW. Our data indicate that loading estimations from early musculoskeletal gait models at both high and low knee joint flexion angles should be interpreted carefully.

AB - Over the past decade, catheter ablation for atrial fibrillation has emerged as an important rhythm control strategy. One of the most dreaded complications of this procedure is atrio-esophageal (AE) fistula formation, which is relatively rare but usually fatal. Esophageal tissue injury during ablation appears to be a precursor to the formation of AE fistulae. Luminal esophageal temperature (LET) monitoring is one of the most commonly utilized strategies to mitigate this risk, despite little evidence that it reduces esophageal injury. The incidence of AE fistulae appears to be on the rise, despite the widespread use of LET monitoring. This may be due to the advent of improved large lesion technology including force sensing catheters and the use of high power, although AE fistulae have also been observed with the use of low power along the left atrial posterior wall. Currently available discrete sensors probes, whether single or multiple, do not appear to significantly reduce injury rates. The purpose of this manuscript is to systematically review the incidence of esophageal thermal injury with and without LET monitoring and review the factors that may be associated with increased risk of injury. PMID- 30282589 TI - Trends of cost-effectiveness studies in sleep medicine. AB - Economic analyses, and cost-effectiveness studies in particular, are increasingly used in medicine and population health to inform policy making and resource allocation. Health economic models have successfully captured sleep medicine outcomes. This study provides an overview of the growth of the use of cost effectiveness analyses to quantify the outcomes of sleep related interventions. It also identifies highly prevalent sleep disorders, which despite having a high burden of disease, lack basic utility studies. PMID- 30282590 TI - Precision Medicine through Antisense Oligonucleotide-Mediated Exon Skipping. AB - Clinical implementation of two recently approved antisense RNA therapeutics - Exondys51(r) to treat Duchenne muscular dystrophy (Duchenne MD) and Spinraza(r) as a treatment for spinal muscular atrophy (SMA) - highlights the therapeutic potential of antisense oligonucleotides (ASOs). As shown in the Duchenne and Becker cases, the identification and specific removal of 'dispensable' exons by exon-skipping ASOs could potentially bypass lethal mutations in other genes and bring clinical benefits to affected individuals carrying amenable mutations. In this review, we discuss the potential of therapeutic alternative splicing, with a particular focus on targeted exon skipping using Duchenne MD as an example, and speculate on new applications for other inherited rare diseases where redundant or dispensable exons may be amenable to exon-skipping ASO intervention as precision medicine. PMID- 30282591 TI - Time to chemotherapy in ovarian cancer: Compliance with ovarian cancer quality indicators at a National Cancer Institute-designated Comprehensive Cancer Center. AB - OBJECTIVE: To assess compliance with, and outcomes related to, the Society of Gynecologic Oncology quality measure in ovarian cancer to administer chemotherapy within 42 days of cytoreductive surgery in patients with epithelial ovarian/fallopian tube/peritoneal cancer. METHODS: Institutional ovarian cancer database was evaluated for compliance with the quality measure to administer chemotherapy within 42 days of cytoreductive surgery. The influence of chemotherapy timing on the risk of death was evaluated, and factors related to the timing of chemotherapy after surgery was assessed. RESULTS: Of 668 patients with epithelial ovarian/fallopian tube/peritoneal cancer who underwent surgical treatment for their disease (primary or interval), 635 met criteria for administration of adjuvant chemotherapy (with stages IA/IB, grade 2 or 3 disease; stage IC or more advanced stage disease). Compliance to administer chemotherapy within 42 days was 59.1%. The adjusted risk of death was not strongly associated with time to chemotherapy within 42 days (aHR: 0.80; 0.61, 1.05) and this did not differ by primary or interval debulking surgery. CONCLUSIONS: In this prospectively maintained database, 59.1% of patients received chemotherapy within 42 days of surgery. The time to chemotherapy interval of within 42 days was not strongly associated with improved survival, particularly when age, stage of disease, insurance enrollment and surgical characteristics were taken into account. Further, the relationship between time to chemotherapy interval of within 42 days and survival did not vary by patients who received primary versus interval debulking surgery or had no residual disease.

PMID- 30282595 TI - The Learning Process of Endoscopic Spinal Surgery for Degenerative Cervical and Lumbar Disorders Using the EasyGO! System. AB - BACKGROUND: Among spinal surgeons, the safety of endoscopic spinal techniques has been criticized as the result of a prolonged learning curve and divergent surgical technique from traditional microsurgery. In this manuscript, the authors assessed the learning curve of 4 experienced microsurgical neurosurgeons in endoscopic spinal surgery. METHODS: Retrospectively, the surgical reports, the endoscopic video recording, and the files of all patients who underwent an endoscopic procedure for the treatment of cervical and lumbar disc herniation from January 2011 to December 2017 were reviewed. The learning process was assessed via several parameters: surgical time, intraoperative complications, dural tear, nerve root injury, conversion to microsurgery, new postoperative neurologic deficits, repeated procedure, and early recurrent disc herniation. RESULTS: The learning process of for 4 surgeons was assessed on the basis of 308 procedures. The mean surgical time for the initial procedure ranges from 58 to 97 minutes and improved to 51-85 minutes for the last procedures. A shorter surgical time had no influence on the rate of intraoperative complication and repeated procedure. Increased working space had a significant influence on the surgical time. The number of procedure to reach the asymptote varied from 10 to 20 depending on the endoscopic system and the surgeon. CONCLUSIONS: The learning process in endoscopic tubular-assisted spinal surgery is variable, and the asymptote might be reached after 10-20 procedures. The amount of working space and instrument angulation affects the surgical time. The decrease of surgical time had no significant influence on the rate of intraoperative complication and repeated procedures.

PMID- 30282597 TI - Percutaneous closure of patent foramen ovale in patients with cryptogenic stroke An updated comprehensive meta-analysis. AB - BACKGROUND: The ideal treatment strategy for patients with cryptogenic stroke and patent foramen ovale (PFO) is not yet clear. Previous randomized controlled trials (RCTs) comparing transcatheter PFO closure with medical therapy in patients with cryptogenic stroke to prevent recurrent ischemic stroke showed mixed results. This meta-analysis aims to compare rates of recurrent stroke, transient ischemic attack (TIA) and all-cause mortality with PFO closure and medical therapy vs. medical therapy alone. METHODS: PubMed and the Cochrane Center Register of Controlled Trials were searched for studies published through June 2018, comparing PFO closure plus medical therapy versus medical therapy alone. Six RCTs (n = 3750) comparing PFO closure with medical therapy were included in the analysis. End points were recurrent stroke, TIA and all-cause mortality. The odds ratios (OR) with 95% confidence interval (CI) were computed and p < 0.05 was considered as a level of significance. RESULTS: A total of 1889 patients were assigned to PFO closure plus medical therapy and 1861 patients were assigned to medical therapy only. Risk of recurrent stroke was significantly lower in the PFO closure plus medical therapy group compared to medical therapy alone. (OR 0.47, 95% CI 0.33-0.67, p < 0.0001). Rate of TIA was similar between the two groups (OR 0.76, 95% CI 0.52-1.14), p = 0.18). There was no difference in all-cause mortality between two groups (OR 0.73, CI 0.33-1.58, p = 0.42). Patients undergoing PFO closure were more likely to develop transient atrial fibrillation than medical therapy alone (OR: 5.85; CI: 3.06-11.18, p <=0.0001) whereas the risk of bleeding was similar between the groups (OR: 0.93; CI: 0.55 1.57, p = 0.78). CONCLUSIONS: The results of this meta-analysis suggest that transcatheter closure of PFO plus medical therapy is superior to medical therapy alone for the prevention of recurrent cryptogenic stroke. However, PFO closure in these patients has not been shown to reduce the risk of recurrent TIA or all cause mortality. There is a higher rate of transient atrial fibrillation post PFO closure device placement, the long-term effects of which have yet to be studied. PMID- 30282598 TI - Relation of Anterior Cruciate Ligament Tears to Potential Chronic Cardiovascular diseases. AB - We have enrolled a cohort of former National Football League players (n = 3,506) who played since 1960 to assess potential long term health consequences associated with participating in the sport. Each participant has completed a self administered questionnaire including reporting of physician-diagnosed health conditions. One of the early assessments was to evaluate whether anterior cruciate ligament (ACL) tears were associated with later life co-morbidities, including cardiovascular effects. We used Cox proportional hazards to estimate hazard ratios (HR) for joint replacement surgeries, myocardial infarction, sleep apnea, arthritis, dementia, and stroke by history of ACL tear during their professional career. For additional outcomes without date of occurrence reported we used logistic regression to estimate odds ratios adjusted for potential confounding variables in all models. After adjusting for covariates, former National Football League players who tore their ACL had approximately a twofold increase in muscular skeletal co-morbidities, including knee joint replacement and arthritis, compared with those without ACL tears. In addition, those with a history of ACL tears also had more than a 50% increased risk of myocardial infarction (HR 1.52; 95% confidence interval 0.97 to 2.38) and a slight increase in sleep apnea (HR 1.15; 95% confidence interval 0.96 to 1.38). ACL tears sustained by athletes may increase the risk of co-morbidities beyond the musculoskeletal system. As there are more than 100,000 ACL reconstructions annually in the United States, our findings could have widespread public health importance if these findings generalize to a population beyond professional football players. In conclusion, enhanced screening for other risk factors for these conditions in patients who have torn their ACL might identify those who could most benefit from prevention strategies. PMID- 30282599 TI - Potassium levels and risk of in-hospital arrhythmias and mortality in patients admitted with suspected acute coronary syndrome. AB - BACKGROUND: In acute coronary syndrome (ACS), potassium imbalance at admission has been associated with in-hospital arrhythmias, cardiac arrest, and mortality. However, several important presentation characteristics and subtype of ACS have not been considered. METHODS: Consecutive patients (n = 32,955) admitted with suspected ACS between 2006 and 2011, registered in the Swedish Web-System for Enhancement and Development of Evidence-Based care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART) and the Stockholm CREAtinine Measurements (SCREAM) project were included. Associations between admission plasma potassium categories (reference 3.5-<4.0 mmol/L) and in-hospital outcomes including mortality, cardiac arrest, new-onset atrial fibrillation, and second- or third-degree atrioventricular block were assessed with logistic regression models. Covariates included demographics, presentation characteristics, comorbidities, estimated glomerular filtration rate (eGFR), main diagnosis, and medication on admission. RESULTS: U-shaped associations between admission potassium, mortality and cardiac arrest were observed. However, in fully adjusted models, only hyperkalemia (5.0-<5.5 [OR 1.83; 95% CI, 1.34-2.49] and >=5.5 mmol/L [OR 2.27; 95% CI, 1.57-3.27]) was associated with mortality, while only hypokalemia (3.0-<3.5 [OR 1.63; 95% CI, 1.21-2.19] and <3.0 mmol/L [OR 2.72; 95% CI, 1.56-4.74]) was associated with cardiac arrest. Potassium <3.0 mmol/L (OR 1.93; 95% CI, 1.00-3.76) was associated with new-onset atrial fibrillation. After multivariable adjustment, no association was observed between potassium and second- or third-degree atrioventricular block. Results were not modified by main diagnosis (ACS subtype or non-ACS diagnosis) or eGFR. CONCLUSIONS: Hyperkalemia at admission is associated with in-hospital mortality and hypokalemia with cardiac arrest and new-onset atrial fibrillation in patients admitted with suspected ACS. PMID- 30282600 TI - Differential prognosis of vasospastic angina according to presentation with sudden cardiac arrest or not: Analysis of the Korean Health Insurance Review and Assessment Service. AB - BACKGROUND: The long-term prognosis of vasospastic angina (VSA) patients presenting with aborted sudden cardiac death (ASCD) is still unknown. We sought to compare the long-term clinical outcomes between VSA patients presenting with and without ASCD by retrospective analysis of a nationwide population-based database. METHODS: A total of 6972 patients in the Health Insurance Review and Assessment database who were hospitalized in the intensive care unit with VSA between July 1, 2007 and May 31, 2015 were enrolled. Primary outcome was the composite of cardiac arrest and acute myocardial infarction after discharge. RESULTS: Five hundred ninety-eight (8.6%) VSA patients presented with ASCD. On inverse probability of treatment weighting, ASCD patients had a significantly increased risk of the composite of cardiac arrest and acute myocardial infarction (adjusted hazard ratio, 2.52; 95% confidence interval, 1.72-3.67; p < 0.001) during the median follow-up duration of 4 years. The association of ASCD presentation with a worse outcome in terms of primary outcome was consistent across various subgroups, including comorbidity type and use of vasodilators (all p-values for interaction: non-significant). ASCD patients treated with an implantable cardioverter defibrillator (ICD) had a lower incidence of the composite of cardiac arrest and acute myocardial infarction during follow-up than those without an ICD (p = 0.009). CONCLUSIONS: VSA patients that present with ASCD are at increased risk of cardiac arrest or myocardial infarction during long term follow-up despite adequate vasodilator therapy. An ICD is a potential therapeutic option for secondary prevention. PMID- 30282601 TI - Accuracy of cadmium-zinc-telluride imaging in detecting single and multivessel coronary artery disease: Is there any gender difference? AB - PURPOSE: To evaluate gender-related differences in diagnostic accuracy of cadmium zinc-telluride (CZT) myocardial perfusion imaging in detecting single- and multi vessel coronary artery disease (CAD). METHODS: We prospectively enrolled 1161 consecutive patients with known or suspected coronary artery disease (288, 25% women and 873, 75% men) who had been referred to our laboratory for stress-rest myocardial perfusion imaging (single-day stress-rest protocol, mean radiation dose: 4 mSv). All patients underwent coronary angiography within 30 days; significant CAD was defined in the presence of a coronary stenosis >70%. Summed stress scores (SSS), summed rest scores (SRS) and summed difference scores (SDS) were obtained. Image quality was graded "good" or better in >90% of patients. RESULTS: On coronary angiography, left main trunk, left anterior descending artery, left circumflex artery and right coronary artery obstructive stenosis were seen in 13, 486, 393 and 499 patients, respectively. Global SSS was the best predictor of CAD in women (AUC = 0.866, 81% sensitivity and 79% specificity) and in men (AUC = 0.871, 76% sensitivity and 84% specificity). Interestingly, its accuracy was maintained also in patients with two-vessel (women: AUC = 0.842, p < 0.001; men: AUC 0.839, p < 0.001) or three-vessel disease (women: AUC = 0.800, p < 0.001; men: AUC 0.804, p < 0.001). There was no gender-related difference in terms of diagnostic accuracy. CONCLUSIONS: Evaluation of multivessel disease can be obtained by CZT camera in men as well as in women, with high accuracy at a lower radiation exposure. PMID- 30282602 TI - Midregional pro-A-type natriuretic peptide as part of a dual biomarker strategy for the early rule out of non-ST segment elevation acute coronary syndrome - The WilCop study. AB - BACKGROUND: Mr-proANP is a biomarker produced in atrial and left ventricular myocardium. We investigated the effect of combined measurement of mr-proANP and high-sensitive cardiac Troponin I assay of the penultimate generation (s-cTnI) for an early type-1 and type-2 NSTE-ACS rule-out with emphasis on the very early presenters' subgroup with symptom onset time (SOT) <= 2 h. METHODS: This was a prospective cohort study of 311 consecutive patients admitted to ER with symptoms suggestive of an acute coronary syndrome (ACS). All patients had baseline mr proANP and s-cTnI measurements. RESULTS: Of the total cohort, 17.6% (n = 55) had final diagnosis of NSTE-ACS: 9.6% (n = 30) had an angiographically-confirmed type 1 infarction and 8.0% (n = 25) had type-2 infarction. In the subgroup of very early presenters (SOT <= 2 h) the negative predictive value (NPV) of s-cTnI for type-1 NSTE-ACS was 96.7% (95%-CI: 87.5-99.4) and the NPV of mr-proANP was 100% (95%-CI: 87.1-100). The dual biomarker strategy yielded an NPV of 100% (95%-CI: 86.7-100). In the same time-related subgroup, the NPV of s-cTnI alone for type-2 was 98.3% (95%-CI: 89.8-99.9) and the NPV of mr-proANP was 97.0% (95%-CI: 82.5 100). The combination of biomarker increased the NPV to 100% (95%-CI: 86.7-100). CONCLUSIONS: Our study demonstrated an immediate release pattern of mr-proANP in NSTE-ACS that may bridge the silent troponin time phenomenon when highest sensitivity cardiac troponin assays are not used. This concept performed best in the very early presenters' subgroup with an excellent NPV of 100% and might result in an early rule-out of NSTE-ACS thus accelerating the diagnostic work-up.

AB - Cytochrome c (cyt c) is a small globular hemoprotein with the main function as an electron carrier in mitochondrial respiratory chain. Cyt c possesses also peroxidase-like activity in the native state despite its six-coordinated heme iron. In this work, we studied the effect of increasing urea concentration in the range from 0 M to 6 M at pH 7 (pH value of the bulk solvent) and pH 5 (pH value close to negatively charged membrane) on peroxidase-like activity of cyt c. We show that peroxidase-like activity, measured by guaiacol oxidation and the ferrous oxidation in xylenol orange methods, correlates with the accessibility of the heme iron, which was assessed from the association rate constant of cyanide binding to cyt c. Cyt c peroxidase-like activity linearly increases in the pre denaturational urea concentrations (0-4 M) at both studied pHs without an apparent formation of penta-coordinated state of the heme iron. Our results suggest that dynamic equilibrium among the denaturant-induced non-native coordination states of cyt c, very likely due to reversible unfolding of the least stable foldons, is pre-requisite for enhanced peroxidase-like activity of cyt c in its compact state. Dynamic replacement of the native sixth coordination bond of methionine-80 by lysines (72, 73, and 79) and partially also by histidines (26 and 33) provides an efficient way how to increase peroxidase-like activity of cyt c without significant conformational change at physiological conditions. PMID- 30282603 TI - Clinically relevant thresholds for ultrasensitive HIV drug resistance testing: a multi-country nested case-control study. AB - BACKGROUND: Implementation of ultrasensitive HIV drug resistance tests for routine clinical use is hampered by uncertainty about the clinical relevance of drug-resistant minority variants. We assessed different detection thresholds for pretreatment drug resistance to predict an increased risk of virological failure. METHODS: We did a case-control study nested within a prospective multicountry cohort. Our study included patients from 12 clinical sites in Kenya, Nigeria, South Africa, Uganda, and Zambia. We defined cases as patients with virological failure (ie, those who had either viral load >=400 copies per mL at 12 months or had switched to second-line antiretroviral therapy [ART] as a result of virological failure before 12 months) and controls as those with viral suppression (viral load <400 copies per mL at 12 months) on first-line non nucleoside reverse transcriptase inhibitor-based antiretroviral therapy. We assessed pretreatment drug resistance with Illumina MiSeq next-generation sequencing, using the International Antiviral Society (IAS)-USA mutation list or the Stanford HIV Drug Resistance Database (HIVDB) genotypic sensitivity score. We calculated diagnostic accuracy measures and assessed the odds of virological failure using conditional logistic regression for 1%, 5%, and 10% pretreatment drug resistance detection thresholds, compared with the conventional 20% or more used in Sanger-based sequencing. FINDINGS: Paired viral load results before ART and at month 12 of follow-up were available from 1896 participants. We identified 178 patients with virological failure and selected 338 matched controls. We excluded 117 patients from pretreatment drug resistance analysis; therefore, 152 cases of virological failure and 247 controls were included in the final analysis. With the IAS-USA mutation list, at a detection threshold of 20% or more in patients with pretreatment drug resistance, the adjusted odds ratio (OR) for virological failure was 9.2 (95% CI 4.2-20.1) compared with those without pretreatment drug resistance. Lowering the threshold resulted in adjusted ORs of virological failure of 6.8 (95% CI 3.3-13.9) at the 10% threshold, 7.6 (3.4-17.1) at the 5% threshold, and 4.5 (2.0-10.2) at the 1% threshold. Lowering the detection threshold from 20% improved the sensitivity (ie, ability to identify cases) from 12% (n=18) to 13% (n=19) at detection threshold 10%, to 15% (n=23) at detection threshold 5%, and to 17% (n=26) at detection threshold 1%, but caused a slight reduction in specificity (ie, ability to identify controls) from 98% (n=241) to 96% (n=238) at the 10% threshold, 96% (n=236) at the 5% threshold, and a larger reduction to 92% (n=227) at the 1% threshold. Diagnostic ORs were 5.4 (95% CI 2.1-13.9) at the 20% threshold, 3.8 (1.7-8.6) at the 10% threshold, 3.8 (1.8-8.1) at the 5% threshold, and 2.3 (1.2-4.2) at the 1% threshold. Use of the Stanford HIVDB genotypic sensitivity scores yielded similar ORs for virological failure, sensitivities, specificities, and diagnostic ORs. INTERPRETATION: Ultrasensitive resistance testing for pretreatment drug resistance improved identification of people at risk of virological failure; however, this came with a reduction in our ability to identify people with viral suppression, especially at very low thresholds. Further modelling is needed to estimate the optimal trade off for the 5% and 20% thresholds, balancing improved case finding against unnecessary regimen switching.

PMID- 30282606 TI - Improved substrate specificity for D-galactose of L-arabinose isomerase for industrial application. AB - L-Arabinose isomerase isolated from Geobacillus stearothermophilus (GSAI) was modified to improve its substrate specificity for D-galactose for the production of D-tagatose, a potential reduced-energy sweetener. Among the selected residues, mutation at residue 18 produced a mutant strain, H18T, which exhibited increased activity for D-galactose compared with the wild-type (WT) enzyme. Analysis of the substrate specificity of H18T showed a 45.4% improvement for D-galactose. Replacing histidine with threonine at residue 18 resulted in approximately 2.7 fold and 1.8-fold higher substrate binding and catalytic efficiency, respectively, for D-galactose. Further enhancement of the specific activity and catalytic efficiency of H18T for D-galactose by up to 2.7-fold and 4.3-fold, respectively, was achieved by adding borate during L-arabinose isomerase catalysis. Moreover, H18T showed thermostability and no destabilization was detected, which is promising for the industrial production of D-tagatose. PMID- 30282607 TI - Proteomic analyses reveal GNG12 regulates cell growth and casein synthesis by activating the Leu-mediated mTORC1 signaling pathway. AB - In cow mammary epithelial cells (CMECs), cell growth and casein synthesis are regulated by amino acids (AAs), and lysosomes are important organelles in this regulatory process, but the mechanisms remain unclear. Herein, lysosomal membrane proteins (LMPs) in CMECs in the presence (Leu+) and absence (Leu-) of leucine were quantitatively analysed using Sequential Windowed Acquisition of All Theoretical Fragment Ion (SWATH) mass spectrometry. In identified LMPs, Guanine nucleotide-binding protein subunit gamma-12 (GNG12) was a markedly up-regulated protein in Leu+ group. CMECs were treated with Leu+ or Leu-, expression and lysosomal localization of GNG12 were decreased in response to Leu absence. Overexpressing or inhibiting GNG12 demonstrated that cell growth, casein synthesis and activation of the mammalian target of rapamycin complex 1 (mTORC1) signaling pathway were all up-regulated by GNG12. Cell growth, casein synthesis and mTORC1 signaling pathway were decreased in response to Leu absence, but these decreases were partially restored by GNG12 overexpression, and those effects were partially reversed by inhibiting GNG12. Co-immunoprecipitation analysis showed that GNG12 activates the mTORC1 pathway via interaction with Ragulator. Taken together, these results suggest that GNG12 is a positive regulator of the Leu mediated mTORC1 signaling pathway in CMECs that promotes cell growth and casein synthesis. PMID- 30282608 TI - Macromolecular crowding-induced molten globule states of the alkali pH-denatured proteins. AB - Structural and molecular properties extracted from circular dichroism (CD), tryptophan fluorescence and 1-anilino-8-napthalene sulfonate (ANS) binding experiments suggest that the high concentration of synthetic crowding agents (dextran 40, dextran 70 and ficoll 70) stabilizes and refolds the base-denatured ferricytochrome c (Ferricyt c) and lysozyme (Lyz) at pH 12.9 (+/-0.1) to molten globule (MG) states (CB-states). These results further revealed that the CB states resemble the generic properties of MG-states. Thermodynamic analysis of thermal denaturation curves of base-denatured Ferricyt c and Lyz at pH 12.9 (+/ 0.1) under variable concentrations of crowding agents (dextran 40, dextran 70 and ficoll 70) revealed that the crowder presence increases the thermal stability of base-denatured proteins and also prevents the cold denaturation of Ferricyt c. The results further showed that the nature, size and shape of crowder influence the crowding-mediated increase in secondary structure stabilization and thermal stability of base-denatured Ferricyt c and Lyz. Analysis of kinetic and thermodynamic parameters measured for CO association reaction of alkaline ferrocytochrome c (Ferrocyt c) at pH 12.9 (+/-0.1) under variable concentrations of crowding agents (dextran 40, dextran 70 and ficoll 70) revealed that the crowder presence reduces the level of structural fluctuation of M80-containing Omega-loop that control CO association to alkaline Ferrocyt c. PMID- 30282609 TI - myo-Inositol dehydrogenase and scyllo-inositol dehydrogenase from Lactobacillus casei BL23 bind their substrates in very different orientations. AB - Many bacteria can use myo-inositol as the sole carbon source using enzymes encoded in the iol operon. The first step is catalyzed by the well-characterized myo-inositol dehydrogenase (mIDH), which oxidizes the axial hydroxyl group of the substrate to form scyllo-inosose. Some bacteria, including Lactobacillus casei, contain more than one apparent mIDH-encoding gene in the iol operon, but such redundant enzymes have not been investigated. scyllo-Inositol, a stereoisomer of myo-inositol, is not a substrate for mIDH, but scyllo-inositol dehydrogenase (sIDH) enzymes have been reported, though never observed to be encoded within the iol operon. Sequences indicate these enzymes are related, but the structural basis by which they distinguish their substrates has not been determined. Here we report the substrate selectivity, kinetics, and high-resolution crystal structures of the proteins encoded by iolG1 and iolG2 from L. casei BL23, which we show encode a mIDH and sIDH, respectively. Comparison of the ternary complex of each enzyme with its preferred substrate reveals the key variations allowing for oxidation of an equatorial versus an axial hydroxyl group. Despite the overall similarity of the active site residues, scyllo-inositol is bound in an inverted, tilted orientation by sIDH relative to the orientation of myo-inositol by mIDH. PMID- 30282610 TI - Structural and functional analysis of miraculin-like protein from Vitis vinifera. AB - The so-called miraculin-like proteins (MLPs) are homologous to miraculin, a homodimeric protein with taste-modifying activity that converts sourness into sweetness. The identity between MLPs and miraculin generally ranges from 30% to 55%, and both MLPs and miraculin are categorized into the Kunitz-type soybean trypsin inhibitor (STI) family. MLP from grape (Vitis vinifera; vvMLP) exhibits significant homology to miraculin (61% identity), suggesting that vvMLP possesses miraculin-like properties. The results of size-exclusion chromatography and sensory analysis illustrated that vvMLP exists as a monomer in solution with no detectable taste-modifying activity. Crystal structure determination revealed that vvMLP exists as a beta-trefoil fold, similarly as other MLPs and Kunitz-type protein inhibitors. The conformation of the loops, including the so-called reactive loop in the STI family, was substantially different between vvMLP and STI. Recombinant vvMLP had inhibitory activity against trypsin (Ki = 13.7 MUM), indicating that the protein can act as a moderate trypsin inhibitor.

In this study, we report 1,4-naphthoquinone (NPQ) as a dual inhibitor of two key enzymes of FAS II pathway, namely FabD (Malonyl-CoA:ACP transacylase) and FabZ (beta-hydroxyacyl-ACP dehydratase). Mode of inhibition of NPQ was found to be non competitive for both enzymes with IC50 of 26.67 MUMU and 23.18 MUMU against McFabZ and McFabD respectively. Conformational changes in secondary and tertiary structures marked by the loss of helical contents were observed in both enzymes upon NPQ binding. The fluorescence quenching was found to be static with a stable ground state complex formation. ITC based studies have shown that NPQ is binding to McFabZ with a stronger affinity (~1.5*) as compared to McFabD. Molecular docking studies have found that NPQ interacts with key residues of both McFabD (Ser209, Arg126, and Leu102) and McFabZ (His74 and Tyr112) enzymes. Both complexes have shown the structural stability during the 20 ns run of molecular dynamics based simulations. Altogether, the present study suggests that NPQ scaffold can be exploited as a multi-targeted inhibitor of FAS II pathway, and these biochemical and biophysical findings will further help in the development of potent antibacterial agents targeting FAS II pathway. PMID- 30282612 TI - Binding properties of sterol carrier protein 2 (SCP2) characterized using Laurdan. AB - Sterol carrier protein 2 (SCP2) binds lipids with high affinity and broad specificity. The overall hydrophobicity, fluidity, and dipolar dynamics of the binding site of SCP2 from Yarrowia lipolytica were characterized using the environmentally-sensitive fluorescent probe Laurdan. The study revealed a binding site with an overall polarity similar to that of dichloromethane and an internal phase comparable to that of phospholipid membranes with coexisting solid-ordered and liquid-crystalline states. The fluorescence properties of bound Laurdan also revealed that the binding site of SCP2 can accommodate competitively more than one ligand, with micro and nanomolar dissociation constants. The much higher affinity for the second than for the first ligand implies that the most prominent SCP2 species in the cellular context are those occupied by two ligands. Thus SCP2 may carry a highly populated lipid in the background and a second one, specific for the functional purpose of SCP2. Our findings are important for the characterization of SCP2 biological functions and the design of specific inhibitors. PMID- 30282613 TI - Metal ions-induced stability and function of bimetallic human arginase-I, a therapeutically important enzyme. AB - Recent studies have highlighted the therapeutic importance of bimetallic human arginase-I against hyperargininemia and L-arginine auxotrophic cancers. The longer retention of catalytic activity of the Co2+-enzyme than that of the Mn2+ in human serum is associated with its enhanced therapeutic potential. To understand the basis of this and also to explore the role of a bimetallic center as well as the role of individual metal ions in the stability, we performed a detailed biochemical and biophysical investigation. The thermodynamic and kinetic stabilities of both the holo proteins are found to be significantly higher than the apo form, indicating that an intact bimetallic centre is vital for the enhanced stability of the holo proteins. The Co2+-protein is found to be more stable than that of the Mn2+, which might explain its longer retention of activity observed in the serum. Mutational studies demonstrated that the metal ions are individually crucial for both the enhanced stability and catalytic activity. Furthermore, we investigated the underlying mechanism for the effect of heat activation on the holo protein for higher catalytic activity, which is not yet known for arginases. Our data reveal that heat activation significantly increases the stability of the holo protein through a metal-induced increase in the helical content leading to the formation of a kinetically competent enzyme. Thus, the present study provides an in-depth insight into the significance of heat activation and the role of metal ions in human arginase, which may be useful for better understanding of its therapeutic use. PMID- 30282614 TI - Ordered opening of LDL receptor binding domain of human apolipoprotein E3 revealed by hydrogen/deuterium exchange mass spectrometry and fluorescence spectroscopy. AB - Apolipoprotein E3 (apoE3) is an exchangeable apolipoprotein that plays a critical role in cholesterol homeostasis. The N-terminal (NT) domain of apoE3 (residues 1 191) is folded into a helix bundle comprised of 4 amphipathic alpha-helices: H1, H2, H3 and H4, flanked by flexible helices N1 and N2, and Hinge Helix 1 (Hinge H1), at the N-and C-terminal sides of the helix bundle, respectively. The NT domain plays a critical role in binding to the low density lipoprotein receptor (LDLR), which eventually leads to lowering of plasma cholesterol levels. In order to be recognized by the LDLR, the helix bundle has to open and undergo a conformational change. The objective of the study was to understand the mechanism of opening of the helix bundle. Hydrogen/deuterium exchange mass spectrometry (HDX-MS) revealed that apoE3 NT domain adopts several disordered and unfolded regions, with H2 exhibiting relatively little protection against exchange-in compared to H1, H3, and H4. Site-directed fluorescence labeling indicated that H2 not only has the highest degree of solvent exposure but also the most flexibility in the helix bundle. It also indicated that the lipoprotein behavior of H1 was significnatly different from that of H2, H3 and H4. These results suggest that the opening of the helix bundle is likely initiated at the flexible end of H2 and the loop linking H2/H3, and involves movement of H2/H3 away from H1/H4. Together, these observations offer mechanistic insight suggesting a regulated helix bundle opening of apoE3 NT domain can be triggered by lipid binding. PMID- 30282615 TI - Processing of high-titer prions for mass spectrometry inactivates prion infectivity. AB - Prions represent a class of universally fatal and transmissible neurodegenerative disorders that affect humans and other mammals. The prion agent contains a pathologically aggregated form of the host prion protein that can transmit infectivity without any bacterial or viral component and is thus difficult to inactivate using disinfection protocols designed for infectious microorganisms. Methods for prion inactivation include treatment with acids, bases, detergents, bleach, prolonged autoclaving and incineration. During these procedures, the sample is often either destroyed or damaged such that further analysis for research purposes is compromised. In this study we show that a straightforward denaturation and in-gel protease digestion protocol used to prepare prion infected samples for mass spectroscopy leads to the loss of at least 7 logs of prion infectivity, yielding a final product that fails to transmit prion disease in vivo. We further show that the resultant sample remains suitable for mass spectrometry-based protein identifications. Thus, the procedure described can be used to prepare prion-infected samples for mass spectrometry analysis with greatly reduced biosafety concerns. PMID- 30282616 TI - Modification of quaternary structure of Candida albicans GlcN-6-P synthase and its desensitization to inhibition by UDP-GlcNAc by site-directed mutagenesis. AB - Site-directed mutagenesis of the CaGFA1 gene encoding glucosamine-6-phosphate synthase from Candida albicans was performed. Desensitization of the enzyme to inhibition by UDPGlcNAc was achieved upon T487I and H492F substitutions at the UDP-GlcNAc binding site, exchange of D524, S525 and S527 for Ala at the dimer:dimer interface and construction of the tail-lock array (L434R and L460A) at the C-tail region. The first two sets if mutageneses but not the last one resulted in conversion of the tetrameric enzyme into its dimeric form. Evidence for links and communication between the UDP-GlcNAc binding site and the dimer dimer contact areas are presented. The CaGfa1-T487IH492F and CaGfa1-KHSH D524AS525AS527A muteins are the first examples of the successful conversion of eukaryotic GlcN-6-P synthase into its prokaryotic-like version upon rational site directed mutagenesis. PMID- 30282617 TI - The Glucose Control Resistance Scale (GCRS) AB - OBJECTIVE: While past research found family conflict, disordered eating, body image concerns, and anxious self-doubts may affect glucose control (A1C), available measures of adherence mainly focus on management tasks. The goal of the current study was to combine emotional distress and beliefs with decisions on management in a new measure of adolescent resistance to treatment adherence: the 12-item Glucose Control Resistance Scale (GCRS). METHODS: Participants included 135 adolescents and their parents from a pediatric diabetes clinic. Surveys measured family conflict, body image concerns, anxious self-doubts, and glucose control resistance. RESULTS: Factor analysis showed 12 items with loadings of .40 or higher to form the Glucose Control Resistance Scale (GCRS). The scale had adequate reliability and there was a significant correlation between child and parent GCRS scores. One factor, family conflict, was significantly related to A1C levels, but the set of four factors explained a total of 12% of the variance in A1C levels. Of the adolescent demographic variables considered (gender, number of parents at home, age, BMIz), only gender was significantly associated with adolescent perceptions of family conflict. CONCLUSION: The GCRS may allow diabetic care teams to better understand the origin of family conflict perceptions and the motivational beliefs that modify behavior and contribute to independent self-management and glucose control. Each question was designed to be meaningful in interventions by addressing common items of resistance to adherence and impulsive management decisions. The GCRS may be used by providers as an initial short screening survey on an annual or semi-annual basis. PMID- 30282618 TI - Epicardial fat thickness in children with classic congenital adrenal hyperplasia. AB - OBJECTIVE: Epicardial fat thickness (EFT) is an emerging cardiometabolic risk factor and has been shown to be related to atherosclerosis. EFT has not been studied in the context of CAH. This study aimed to evaluate EFT in children with CAH and its relation to carotid intima media thickness (CA-IMT) and left ventricular functions. METHODS: 36 children with classic CAH were compared with 36 healthy controls. All children had confirmed CAH and received steroid substitution therapy. Patients and controls underwent anthropometric evaluation, measurement of fasting lipids, glucose, insulin, homeostasis model assessment for insulin resistance (HOMA-IR), Left ventricular functions and EFT were assessed using conventional echocardiography. Duplex ultrasonography was used to measure CA-IMT. RESULTS: Compared to controls, patients had higher EFT (p=0.001), HOMA IR(p=0.001), CA- IMT (p=0.01), LVMI (p=0.001) and prolonged mitral deceleration time (DcT) (p=0.01).Abnormalities were marked in uncontrolled children on medical treatment. In multivariate analysis in children with classic CAH , EFT correlated positively with waist circumference (OR =1.9,95%Cl=1.07-1.14.p=001), 17-OHP; nmol/l (OR =1.6; 95% CI = 1.33-2.89, p = 0.05), testosterone , ng/dl(OR =1.7; 95% CI = 1.55-2.13, p = 0.01), LVMI (OR=1.14, 95%Cl=1.08-1.13, p=0.0001) , mitral DcT (OR=2.25;95% CI=1.15-2.05, p=0.01) and CA-IMT (OR=1.6 ;95% CI=1.15-2.05, p=0.01). CONCLUSIONS: EFT may be elevated in children with classic CAH particularly those with poor control and is correlated to carotid intima media thickness, left ventricular mass and mitral deceleration time. Measurement of EFT by Echocardiography in CAH children may help to identify those at high risk of developing left ventricular dysfunction and subclinical atherosclerosis. PMID- 30282619 TI - Genetic and clinical characteristics of the patients with Vitamin D Dependent Rickets Type 1A. AB - OBJECTIVE: Vitamin D dependent rickets type 1A (VDDR1A) is an autosomal recessive disorder caused by mutations in the 25OHD 1alpha-hydroxylase gene (CYB27B1). As it may be confused with nutritional rickets and hypophosphatemic rickets, genetic analysis is important for making a correct diagnosis. METHODS: We analysed genomic DNA from 11 patients from 8 different Turkish families. The patients were recruited for our studies if they presented with diagnosis of vitamin D dependent rickets. RESULTS: The mean age at diagnosis was 13.1 +/-7.4 months. Seven patients had mild hypocalcemia at presentation while 4 patients had normal calcium levels. All patients underwent CYP27B1 gene analysis; The most prevalent mutation was the c.195 + 2T>G splice donor site mutation, affecting 5 out of 11 patients with VDDR1A. Two patients from the fourth family was compound heterozygous for c.195 +2T>G and c.195 +2 T>A in intron 1. Two patients from different families were homozygous for a previously reported duplication mutation in exon 8 (1319_1325dupCCCACCC, Phe443Profs*24). One patient had homozygous splice site mutation in intron 7 (c.1215+2 T>A). And one patient had homozygous mutation in exon 9 (c.1474 C>T). CONCLUSION: Intron 1 mutation was the most common mutation as in the previous studies, and all patients carrying that mutation were from same city of origin suggesting a "founder" or a "common ancestor" effect. VDDR1A should be definitely considered when a patient with signs of rickets has a normal 25-OH level or when there is unresponsiveness to vitamin D treatment. PMID- 30282620 TI - Effectiveness of the Malnutrition eLearning Course for Global Capacity Building in the Management of Malnutrition: Cross-Country Interrupted Time-Series Study. AB - BACKGROUND: Scaling up improved management of severe acute malnutrition has been identified as the nutrition intervention with the largest potential to reduce child mortality, but lack of operational capacity at all levels of the health system constrains scale-up. We therefore developed an interactive malnutrition eLearning course that is accessible at scale to build capacity of the health sector workforce to manage severely malnourished children according to the guidelines of the World Health Organization. OBJECTIVE: The aim of this study was to test whether the malnutrition eLearning course improves knowledge and skills of in-service and preservice health professionals in managing children with severe acute malnutrition and enables them to apply the gained knowledge and skills in patient care. METHODS: This 2-year prospective, longitudinal, cross country, interrupted time-series study took place in Ghana, Guatemala, El Salvador, and Colombia between January 2015 and February 2017. A subset of 354 in service health personnel from 12 hospitals and 2 Ministries of Health, 703 preservice trainees from 9 academic institutions, and 204 online users participated. Knowledge gained after training and retention over time was measured through pre- and postassessments comprising questions pertaining to screening, diagnosis, pathophysiology and treatment, and prevention of malnutrition. Comprehension, application, and integration of knowledge were tested. Changes in perception, confidence, and clinical practice were assessed through questionnaires and interviews. RESULTS: Before the course, awareness of the World Health Organization guidelines was 36.73% (389/1059) overall, and 26.3% (94/358) among in-service professionals. The mean score gain in knowledge after access to the course in 606 participants who had pre- and postassessment data was 11.8 (95% CI 10.8-12.9; P<.001)-a relative increase of 41.5%. The proportion of participants who achieved a score above the pass mark posttraining was 58.7% (356/606), compared with 18.2% (110/606) in pretraining. Of the in-service professionals, 85.9% (128/149) reported applying their knowledge by changing their clinical practice in screening, assessment, diagnosis, and management. This group demonstrated significantly increased retained knowledge 6 months after training (mean difference [SD] from preassessment of 12.1 [11.8]), retaining 65.8% (12.1/18.4) of gained knowledge from the training. Changes in the management of malnutrition were reported by trained participants, and institutional, operational, and policy changes were also found. CONCLUSIONS: The malnutrition eLearning course improved knowledge, understanding, and skills of health professionals in the diagnosis and management of children with severe acute malnutrition, and changes in clinical practice and confidence were reported following the completion of the course. PMID- 30282621 TI - Behavior Change Techniques in mHealth Apps for the Mental and Physical Health of Employees: Systematic Assessment. AB - BACKGROUND: Employees remain at risk of developing physical and mental health problems. To improve the lifestyle, health, and productivity many workplace interventions have been developed. However, not all of these interventions are effective. Mobile and wireless technology to support health behavior change (mobile health [mHealth] apps) is a promising, but relatively new domain for the occupational setting. Research on mHealth apps for the mental and physical health of employees is scarce. Interventions are more likely to be useful if they are rooted in health behavior change theory. Evaluating the presence of specific combinations of behavior change techniques (BCTs) in mHealth apps might be used as an indicator of potential quality and effectiveness. OBJECTIVE: The aim of this study was to assess whether mHealth apps for the mental and physical health of employees incorporate BCTs and, if so, which BCTs can be identified and which combinations of BCTs are present. METHODS: An assessment was made of apps aiming to reduce the risk of physical and psychosocial work demands and to promote a healthy lifestyle for employees. A systematic search was performed in iTunes and Google Play. Forty-five apps were screened and downloaded. BCTs were identified using a taxonomy applied in similar reviews. The mean and ranges were calculated. RESULTS: On average, the apps included 7 of the 26 BCTs (range 2-18). Techniques such as "provide feedback on performance," "provide information about behavior health link," and "provide instruction" were used most frequently. Techniques that were used least were "relapse prevention," "prompt self-talk," "use follow up prompts," and "provide information about others' approval." "Stress management," "prompt identification as a role model," and "agree on behavioral contract" were not used by any of the apps. The combination "provide information about behavior-health link" with "prompt intention formation" was found in 7/45 (16%) apps. The combination "provide information about behavior-health link" with "provide information on consequences," and "use follow-up prompts" was found in 2 (4%) apps. These combinations indicated potential effectiveness. The least potentially effective combination "provide feedback on performance" without "provide instruction" was found in 13 (29%) apps. CONCLUSIONS: Apps for the occupational setting might be substantially improved to increase potential since results showed a limited presence of BCTs in general, limited use of potentially successful combinations of BCTs in apps, and use of potentially unsuccessful combinations of BCTs. Increasing knowledge on the effectiveness of BCTs in apps might be used to develop guidelines for app developers and selection criteria for companies and individuals. Also, this might contribute to decreasing the burden of work-related diseases. To achieve this, app developers, health behavior change professionals, experts on physical and mental health, and end-users should collaborate when developing apps for the working context. PMID- 30282622 TI - Using Mobile Technology (pMOTAR) to Assess Reactogenicity: Protocol for a Pilot Randomized Controlled Trial. AB - BACKGROUND: Accurate safety monitoring in HIV vaccine trials is vital to eventual licensure and consequent uptake of products. Current practice in preventive vaccine trials, under the HIV Vaccine Trials Network (HVTN), is to capture related side effects in a hardcopy tool. The reconciliation of this tool, 2 weeks after vaccination at the safety visit, is time consuming, laborious, and fraught with error. Unstructured Supplementary Service Data (USSD), commonly used to purchase airtime, has been suggested for collection of safety data in vaccine trials. With saturated access to mobile phones in South Africa, this cheap, accessible tool may improve accuracy and completeness of collected data and prove feasible and acceptable over the hardcopy tool. OBJECTIVE: The objective of our study is to develop and implement a USSD tool for real-time safety data collection that is feasible and acceptable to participants and staff, allowing for a comparison with the hardcopy tool in terms of completeness and accuracy. METHODS: This feasibility study is being conducted at a single study site, the Centre for the AIDS Programme of Research in South Africa eThekwini Clinical Research site, in South Africa. The feasibility study is nested within a parent phase 1/2a preventive HIV vaccine trial (HVTN 108) as an open-label, randomized controlled trial, open to all consenting parent trial participants. Participants are randomly assigned in a 1:1 ratio to the hardcopy or USSD tool, with data collection targeted to the third and fourth injection time points in the parent trial. Online feasibility and acceptability surveys will be completed by staff and participants at the safety visit. We will itemize and compare error rates between the hardcopy tool and the USSD printout and associated source documentation. We hypothesize that the USSD tool will be shown to be feasible and acceptable to staff and participants and to have superior quality and completion rates to the hardcopy tool. RESULTS: The study has received regulatory approval. We have designed and developed the USSD tool to include all the data fields required for reactogenicity reporting. Online feasibility and accessibility surveys in both English and isiZulu have been successfully installed on a tablet. Data collection is complete, but analysis is pending. CONCLUSIONS: Several HIV preventive vaccine trials are active in Southern Africa, making tools to improve efficiencies and minimize error necessary. Our results will help to determine whether the USSD tool can be used in future vaccine studies and can eventually be rolled out.

PMID- 30282623 TI - Arthritis-Related Support in a Social Media Group for Quilting Hobbyists: Qualitative Study. AB - BACKGROUND: People with arthritis are increasingly seeking support online, particularly for information about social role participation while experiencing symptoms of chronic arthritis. Social media enables peer-to-peer support on how serious leisure (eg, hobbies such as quilting) can be adapted to allow participation. Research is needed to understand what type of peer support is provided online and how this support occurs. OBJECTIVE: The aim of our study was to explore what kind of support is offered by fellow hobbyists (with or without arthritis) in response to requests for advice in a social media group. METHODS: Three vignettes were posted on a Facebook quilting group regarding arthritis related symptoms or impairments that affect how people quilt. A Facebook Insights report was used to examine the groups' demographics. Responses to the vignettes were thematically analyzed. RESULTS: The members of the quilting Facebook group were mostly women (18,376/18,478, 99.45%), aged 55 to 64 years, and most were located in the United States. In response to the vignettes, the 22 participants predominantly offered emotional support and shared information. Participants shared their real-life experiences and creative means in adapting medical advice to their crafting. More than half (30/54, 56%) of the advice that was offered aligned with the OrthoInfo medical best practice guidelines relevant to the vignettes. CONCLUSIONS: Serious leisure social media groups can be useful forums for sharing information about arthritis-related issues. People do respond to requests for support and information, although there is a difference between quilting support (eg, "I need a new iron, what should I buy?") and health support (eg, "I have arthritis, what scissors should I buy?"). People provide emotional support for life events on serious leisure social media platforms (eg, offering condolences when a person states that she is making a memory quilt), and this extends to health issues when group members reveal them.

PMID- 30282627 TI - Need for evidence-based early intervention programmes: a public health perspective. AB - This paper attempts to discuss why the early intervention agenda based on the current convention of 'ultra-high risk' (UHR) or 'clinical high risk' (CHR) for 'transition' to psychosis framework has been destined to fall short of generating a measurable and economically feasible public health impact. To summarise: (1) the primary determinant of the 'transition' rate is not the predictive value of the UHR/CHR but the degree of the risk-enrichment; (2) even with a significant pre-test risk enrichment, the prognostic accuracy of the assessment tools in help seeking population is mediocre, failing to meet the bare minimum thresholds; (3) therapeutic interventions arguably prolong the time-to-onset of psychotic symptoms instead of preventing 'transition', given that the UHR/CHR and 'transition' lie on the same unidimensional scale of positive psychotic symptoms; (4) meta-analytical evidence confirms that specific effective treatment for preventing 'transition' (the goal-primary outcome-of the UHR/CHR framework) is not available; (5) the UHR/CHR-'transition' is a precarious target for research given the unpredictability driven by the sampling strategies and the natural ebb and flow of psychotic symptoms within and between individuals, leading to false positives; (6) only a negligible portion of those who develop psychosis benefits from UHR/CHR services (see prevention paradox); (7) limited data on the cost effectiveness of these services exist. Given the pitfalls of the narrow focus of the UHR/CHR framework, a broader prevention strategy embracing pluripotency of early psychopathology seems to serve as a better alternative. Nevertheless, there is a need for economic evaluation of these extended transdiagnostic early intervention programmes.

PMID- 30282629 TI - Defining significant childhood illness and injury in the Emergency Department: a consensus of UK and Ireland expert opinion. AB - BACKGROUND: Clarifying whether paediatric early warning scores (PEWS) accurately predict significant illness is a research priority for UK and Ireland paediatric emergency medicine (EM). However, a standardised list of significant conditions to benchmark these scores does not exist. OBJECTIVES: To establish standardised significant illness endpoints for use in determining the performance accuracy of PEWS and safety systems in emergency departments (ED), using a consensus of expert opinion in the UK and Ireland. DESIGN: Between July 2017 and February 2018, three online Delphi rounds established a consensus on 'significant' clinical conditions, derived from a list of common childhood illness/injury ED presentations. Conditions warranting acute hospital admission in the opinion of the respondent were defined as 'significant', using a 5-point Likert scale. The consensus was a priori >=80% (positive or negative). 258 clinical conditions were tested. PARTICIPANTS AND SETTINGS: Eligible participants were consultants in acute or EM paediatrics, or adult EM, accessed via 53 PERUKI (Paediatric Emergency Research in the UK and Ireland)'s research collaborative sites, and 27 GAPRUKI (General and Adolescent Paediatric Research in the UK and Ireland)'s sites, 17 of which overlap with PERUKI. MAIN OUTCOME MEASURES: To create a list of conditions regarded as 'significant'with >=80% expert consensus. RESULTS: 43 (68%) of 63 PERUKI and GAPRUKI sites responded; 295 experts were invited to participate. Participants in rounds 1, 2 and 3 were 223 (76%), 177 (60%) and 148 (50%), respectively; 154 conditions reached positive consensus as 'significant'; 1 condition reached a negative consensus (uncomplicated Henoch-Schonlein purpura); and 37 conditions achieved non-consensus. CONCLUSIONS: A list of significant childhood conditions has been created using UK and Irish expert consensus, for research purposes, for the first time. This will be used as the benchmark endpoint list for future research into PEWS/safety systems performance in EDs. PMID- 30282630 TI - Symptom-triggered therapy for assessment and management of alcohol withdrawal syndrome in the emergency department short-stay clinical decision unit. AB - INTRODUCTION: We previously reported that benzodiazepine detoxification for alcohol withdrawal using symptom-triggered therapy (STT) with oral diazepam reduced length of stay (LOS) and cumulative benzodiazepine dose by comparison with standard fixed-dose regimen. In this study, we aim to describe the feasibility of STT in an emergency department (ED) short-stay clinical decision unit (CDU) setting. METHODS: In this retrospective cohort study, we describe our experience with STT over a full calendar year (2014) in the CDU. A retrospective chart review was conducted and data collection included demographics, clinical details, total cumulative dose of diazepam, receipt of parenteral thiamine, LOS and disposition. RESULTS: 5% (n=174) of 3222 admissions to CDU required STT. Collapse or seizure (41%, n=71) and alcohol withdrawal (21%, n=37) were the most common reasons recorded for admission to CDU in those who required STT. Median Alcohol Use Disorders Identification Test score was 25 and 112 patients (64%) had at least one Clinical Institute Withdrawal Assessment for Alcohol revised measurement >=10, triggering a dose of diazepam (20 mg). The median cumulative oral diazepam dose was 20 mg while 24 (15%) patients received a cumulative dose of 100 mg or more. Median time for STT was 12 hours (IQR=12, R=1-48). 3% (n=5) of patients required further general hospital admission and median LOS in CDU, was 22 hours (IQR=20, R=1-168). CONCLUSION: STT is potentially feasible as a rapid and effective approach to managing alcohol withdrawal syndrome in the ED/CDU short-stay inpatient setting where patient LOS is generally less than 24 hours.

AB - Epithelial-to-mesenchymal transition (EMT) plays pivotal roles in a variety of biological processes, including cancer invasion. Although EMT involves alterations of cytoskeletal proteins such as microtubules, the role of microtubules in EMT is not fully understood. Microtubule dynamics are regulated by microtubule-binding proteins, and one such protein is CAMSAP3, which binds the minus-end of microtubules. Here, we show that CAMSAP3 is important to preserve the epithelial phenotypes in lung carcinoma cells. Deletion of CAMSAP3 in human lung carcinoma-derived cell lines showed that CAMSAP3-deficient cells acquired increased mesenchymal features, mostly at the transcriptional level. Analysis of the mechanisms underlying these changes demonstrated that tubulin acetylation was dramatically increased following CAMSAP3 removal, leading to the upregulation of Akt proteins (also known as protein kinase B proteins, hereafter Akt) activity, which is known to promote EMT. These findings suggest that CAMSAP3 functions to protect lung carcinoma cells against EMT by suppressing Akt activity via microtubule regulation and that CAMSAP3 loss promotes EMT in these cells.This article has an associated First Person interview with the first author of the paper.

AB - Chronic obstructive pulmonary disease (COPD) and cardiovascular disease (CVD) frequently occur together and their coexistence is associated with worse outcomes than either condition alone. Pathophysiological links between COPD and CVD include lung hyperinflation, systemic inflammation and COPD exacerbations. COPD treatments may produce beneficial cardiovascular (CV) effects, such as long acting bronchodilators, which are associated with improvements in arterial stiffness, pulmonary vasoconstriction, and cardiac function. However, data are limited regarding whether these translate into benefits in CV outcomes. Some studies have suggested that treatment with long-acting beta2-agonists and long acting muscarinic antagonists leads to an increase in the risk of CV events, particularly at treatment initiation, although the safety profile of these agents with prolonged use appears reassuring. Some CV medications may have a beneficial impact on COPD outcomes, but there have been concerns about beta-blocker use leading to bronchospasm in COPD, which may result in patients not receiving guideline-recommended treatment. However, there are few data suggesting harm with these agents and patients should not be denied beta-blockers if required. Clearer recommendations are necessary regarding the identification and management of comorbid CVD in patients with COPD in order to facilitate early intervention and appropriate treatment. PMID- 30282636 TI - Activin/Smad2 and Wnt/beta-catenin up-regulate HAS2 and ALDH3A2 to facilitate mesendoderm differentiation of human embryonic stem cells. AB - Activin and Wnt signaling are necessary and sufficient for mesendoderm (ME) differentiation of human embryonic stem cells (ESCs). In this study, we report that during ME differentiation induced by Activin and Wnt, Activin/Smad2 induces a decrease of the repressive histone modification of H3K27me3 by promoting the proteasome-dependent degradation of enhancer of zeste 2 polycomb (EZH2) repressive complex 2 subunit. As a result, recruitment of the forkhead protein FOXH1 on open chromatin regions integrates the signals of Activin/Smad2 and Wnt/beta-catenin to activate the expression of the ME genes including HAS2 and ALDH3A2 Consistently, H3K27me3 decrease is enriched on open chromatin around regulatory regions. Furthermore, knockdown of HAS2 or ALDH3A2 greatly attenuates ME differentiation. These findings unveil a pathway from extracellular signals to epigenetic modification-mediated gene activation during ME commitment.

AB - The innate immune system is important for the efficacy of vaccines, but excessive innate immune responses can cause adverse reactions after vaccination. Extracellular vesicles (EVs) are enriched in the blood and can deliver functional RNAs, such as microRNAs (miRNAs), to recipient cells, thereby mediating intercellular communication. However, the role of EVs in controlling the innate immune responses to vaccines has not been fully elucidated. Here, we found that miR-451a is abundant in human serum EVs and that its presence in blood circulating EVs affects the innate immune responses of macrophages and dendritic cells to inactivated whole-virus vaccines (WV) against influenza. miR-451a in human serum EVs was stable for a week in healthy subjects, and its levels gradually fluctuated over several months. miR-451a within serum EVs was internalized into serum-cultured macrophages and dendritic cells and reduced endogenous 14-3-3zeta protein levels and decreased the expression of type I IFN and interleukin 6 in response to WV stimulation. miR-451a levels in blood circulating EVs were positively correlated with intracellular miR-451a levels in mouse splenic CD11c+ cells and inversely correlated with the innate immune response to inactivated WV in vivo These findings suggest that miR-451a in circulating EVs is internalized into recipient cells in vivo and that this internalization results in an attenuation of the innate immune response to WV. Moreover, a microarray analysis identified several other miRNAs that affect the macrophage response to inactivated WV. Our results reveal that miRNAs in circulating EVs significantly modify the responses of macrophages and dendritic cells to inactivated WV.

AB - Oxidative stress triggers and exacerbates neurodegeneration in Alzheimer's disease (AD). Various antioxidants reduce oxidative stress, but these agents have little efficacy due to poor blood-brain barrier (BBB) permeability. Additionally, single-modal antioxidants are easily overwhelmed by global oxidative stress. Activating nuclear factor erythroid 2 (NF-E2)-related factor 2 (Nrf2) and its downstream antioxidant system are considered very effective for reducing global oxidative stress. Thus far, only a few BBB-permeable agents activate the Nrf2 dependent antioxidant system. Here, we discovered a BBB-bypassing Nrf2-activating polysaccharide that may attenuate AD pathogenesis. Mini-GAGR, a 0.7-kDa cleavage product of low-acyl gellan gum, increased the levels and activities of Nrf2 dependent antioxidant enzymes, decreased reactive oxygen species (ROS) under oxidative stress in mouse cortical neurons, and robustly protected mitochondria from oxidative insults. Moreover, mini-GAGR increased the nuclear localization and transcriptional activity of Nrf2 similarly to known Nrf2 activators. Mechanistically, mini-GAGR increased the dissociation of Nrf2 from its inhibitor, Kelch-like ECH-associated protein 1 (Keap1), and induced phosphorylation and nuclear translocation of Nrf2 in a protein kinase C (PKC)- and fibroblast growth factor receptor (FGFR1)-dependent manner. Finally, 20-day intranasal treatment of 3xTg-AD mice with 100 nmol of mini-GAGR increased nuclear p-Nrf2 and growth associated protein 43 (GAP43) levels in hippocampal neurons, reduced p-tau and beta-amyloid (Abeta) peptide-stained neurons, and improved memory. The BBB bypassing Nrf2-activating polysaccharide reported here may be effective in reducing oxidative stress and neurodegeneration in AD. PMID- 30282639 TI - Effects of comprehensive cardiac rehabilitation on functional capacity in a middle-income country: a randomised controlled trial. AB - OBJECTIVE: Despite the growing epidemic of cardiovascular diseases in middle income countries, there is insufficient evidence about cardiac rehabilitation (CR) in these countries. Thus, the effects of comprehensive CR on functional capacity and risk factors were investigated in Brazil, to test the hypothesis that it results in better outcomes than exercise-only or no CR. METHODS: Single blinded, randomised controlled trial with three parallel arms: comprehensive CR (exercise+education) versus exercise-only CR versus wait-list control. Eligible coronary patients were randomised in blocks of four with 1:1:1 concealed allocation. Participants randomised to exercise-only CR received 36 exercise classes; comprehensive CR group also received 24 educational sessions. The primary outcome was incremental shuttle walk test (ISWT) distance; secondary outcomes were cardiovascular risk factors. All outcomes were assessed at baseline and 6 months later. Analysis of covariance was performed on the basis of intention-to-treat (ITT) and per-protocol. RESULTS: 115 (88.5%) patients were randomised; 93 (80.9%) were retained. There were improvements in ISWT distance from pretest to post-test with comprehensive (from 358.4+/-132.6 to 464.8+/-121.6 m; mean change=106.4; p<0.001) and exercise-only (from 391.5+/-118.8 to 488.1+/ 106.3 m; mean change=96.5, p<0.001) CR, with significantly greater functional capacity with comprehensive CR versus control (ITT: mean difference=75.6+/-30.7 m, 95% CI 1.4 to 150.2). There were also reductions in systolic blood pressure with comprehensive CR (ITT: reduction of 6.2+/-17.8 mm Hg, p=0.04). There were no significant differences for other outcomes. CONCLUSION: Results showed clinically significant improvements in functional capacity and blood pressure with CR, and significantly greater functional capacity with comprehensive CR compared with usual care.

AB - INTRODUCTION: Detecting early cardiac involvement in Fabry disease (FD) is important because therapy may alter disease progression. Cardiovascular magnetic resonance (CMR) can detect T1 lowering, representing myocardial sphingolipid storage. In many diseases, early mechanical dysfunction may be detected by abnormal global longitudinal strain (GLS). We explored the relationship of early mechanical dysfunction and sphingolipid deposition in FD. METHODS: An observational study of 221 FD and 77 healthy volunteers (HVs) who underwent CMR (LV volumes, mass, native T1, GLS, late gadolinium enhancement), ECG and blood biomarkers, as part of the prospective multicentre Fabry400 study. RESULTS: All FD had normal LV ejection fraction (EF 73%+/-8%). Mean indexed LV mass (LVMi) was 89+/-39 g/m2 in FD and 55.6+/-10 g/m2 in HV. 102 (46%) FD participants had left ventricular hypertrophy (LVH). There was a negative correlation between GLS and native T1 in FD patients (r=-0.515, p<0.001). In FD patients without LVH (early disease), as native T1 reduced there was impairment in GLS (r=-0.285, p<0.002). In the total FD cohort, ECG abnormalities were associated with a significant impairment in GLS compared with those without ECG abnormalities (abnormal: 16.7+/-3.5 vs normal: -20.2+/-2.4, p<0.001). CONCLUSIONS: GLS in FD correlates with an increase in LVMi, storage and the presence of ECG abnormalities. In LVH negative FD (early disease), impairment in GLS is associated with a reduction in native T1, suggesting that mechanical dysfunction occurs before evidence of sphingolipid deposition (low T1).

AB - CLINICAL INTRODUCTION: A 76-year-old man with 50 years of smoking history was diagnosed in 2012 with diffuse interstitial lung disease, with radiological data of usual interstitial pneumonia. He came to the emergency room presenting with progression of dyspnoea for 1 week, concomitant with loss of 5 kg of weight, anorexia and poor general condition. He had tachypnoea at rest (30 breaths/min), peripheral cyanosis, speech interfered by cough and breathlessness, baseline oxygen saturation 90%, heart rate 40 beats/min and blood pressure 130/70 mm Hg. Chest X-ray was performed and there was basal atelectasia of the right lung. ECG and urgent echocardiogram (transthoracic echocardiogram, TTE) were also performed (figure 1). heartjnl;heartjnl-2018-313779v1/F1F1F1Figure 1(A) ECG.

PMID- 30282642 TI - Successful hematopoietic stem cell mobilization and apheresis collection using plerixafor alone in sickle cell patients. AB - Novel therapies for sickle cell disease (SCD) based on genetically engineered autologous hematopoietic stem and progenitor cells (HSPCs) are critically dependent on a safe and effective strategy for cell procurement. We sought to assess the safety and efficacy of plerixafor when used in transfused patients with SCD for HSC mobilization. Six adult patients with SCD were recruited to receive a single dose of plerixafor, tested at lower than standard (180 ug/kg) and standard (240 ug/kg) doses, followed by CD34+ cell monitoring in peripheral blood and apheresis collection. The procedures were safe and well-tolerated. Mobilization was successful, with higher peripheral CD34+ cell counts in the standard vs the low-dose group. Among our 6 donors, we improved apheresis cell collection results by using a deep collection interface and starting apheresis within 4 hours after plerixafor administration. In the subjects who received a single standard dose of plerixafor and followed the optimized collection protocol, yields of up to 24.5 * 106 CD34+ cells/kg were achieved. Interestingly, the collected CD34+ cells were enriched in immunophenotypically defined long-term HSCs and early progenitors. Thus, we demonstrate that plerixafor can be employed safely in patients with SCD to obtain sufficient HSCs for potential use in gene therapy.

PMID- 30282645 TI - Impact of the NHS Health Check on inequalities in cardiovascular disease risk: a difference-in-differences matching analysis. AB - BACKGROUND: We assessed impacts of a large, nationwide cardiovascular disease (CVD) risk assessment and management programme on sociodemographic group inequalities in (1) early identification of hypertension, type 2 diabetes (T2D) and chronic kidney disease (CKD); and (2) management of global CVD risk among high-risk individuals. METHODS: We obtained retrospective electronic medical records from the Clinical Practice Research Datalink for a randomly selected sample of 138 788 patients aged 40-74 years without known CVD or diabetes, who were registered with 462 practices between 2009 and 2013. We estimated programme impact using a difference-in-differences matching analysis that compared changes in outcome over time between attendees and non-attendees. RESULTS: National Health Service Health Check attendance was 21.4% (29 672/138 788). A significantly greater number of hypertension and T2D incident cases were identified in men than women (eg, an additional 4.02%, 95% CI 3.65% to 4.39%, and 2.08%, 1.81% to 2.35% cases of hypertension in men and women, respectively). A significantly greater number of T2D incident cases were identified among attendees living in the most deprived areas, but no differences were found for hypertension and CKD across socioeconomic groups. No major differences in CVD risk management were observed between sociodemographic subgroups (eg, programme impact on 10-year CVD risk score was -1.13%, -1.48% to -0.78% in male and -1.53%, -2.36% to -0.71% in female attendees). CONCLUSION: During 2009-2013, the programme had low attendance and small overall impacts on early identification of disease and risk management. The age, sex and socioeconomic subgroups appeared to have derived similar level of benefits, leaving existing inequalities unchanged. These findings highlight the importance of population-wide interventions to address inequalities in CVD outcomes. PMID- 30282643 TI - Cell-lineage level-targeted sequencing to identify acute myeloid leukemia with myelodysplasia-related changes. AB - Acute myeloid leukemia (AML) is a clonal myeloid neoplasm that typically arises de novo; however, some cases evolve from a preleukemic state, such as myelodysplastic syndrome (MDS). Such secondary AMLs and those with typical MDS related clinical features are known as AMLs with myelodysplasia-related changes (AML-MRC). Because patients with AML-MRC have poor prognosis, more accurate diagnostic approaches are required. In this study, we performed targeted sequencing of 54 genes in 3 cell populations (granulocyte, blast, and T-cell fractions) using samples from 13 patients with MDS, 16 patients with clinically diagnosed AML-MRC, 4 patients with suspected AML-MRC but clinically diagnosed as AML not otherwise specified (AML-NOS), and 11 patients with de novo AML. We found that overlapping mutations, defined as those shared at least by the blast and granulocyte fractions, were significantly enriched in patients with MDS and AML MRC, including those with suspected AML-MRC, indicating a substantial history of clonal hematopoiesis. In contrast, blast-specific nonoverlapping mutations were significantly enriched in patients with de novo AML. Furthermore, the presence of overlapping mutations, excluding DNMT3A, TET2, and ASXL1, effectively segregated patients with MDS and AML-MRC or suspected AML-MRC from patients with de novo AML. Additionally, the presence of >=3 mutations in the blast fraction was useful for distinguishing patients with AML-MRC from those with MDS. In conclusion, our approach is useful for classifying clinically diagnosable AML-MRC and identifying clinically diagnosed AML-NOS as latent AML-MRC. Additional prospective studies are needed to confirm the utility of this approach. PMID- 30282646 TI - Changes in workplace car parking and commute mode: a natural experimental study. AB - BACKGROUND: The use of private motor vehicles places a considerable burden on public health. Changes in workplace car parking policies may be effective in shifting behaviour. We use a natural experimental design to assess whether changes in policy were associated with differences in commute mode. METHODS: We used cohort data from participants working in Cambridge (2009-2012). Commuters reported their trips and travel modes to work over the last week, workplace car parking policy and socioeconomic, environmental and health characteristics. Changes in policy were defined between phases (1608 transition periods; 884 participants). Using generalised estimating equations, we estimated associations between changes in parking policy and the proportion of trips that (i) were exclusively by motor vehicle, (ii) involved walking or cycling and (iii) involved public transport at follow-up. RESULTS: 25.1% of trips were made by motor vehicle, 54.6% involved walking or cycling and 11.7% involved public transport. The introduction of free or paid workplace parking was associated with higher proportions of motor vehicle trips (11.4%, 95% CI (6.4 to 16.3)) and lower proportions involving walking or cycling (-13.3%, 95% CI (-20.2 to -6.4)) and public transport (-5.8%, 95% CI (-10.6 to -0.9)) compared with those with no workplace parking. Restrictive changes in policy were associated with shifts in the expected direction but these were not statistically significant. CONCLUSION: Relaxation of parking policy was associated with higher proportions of trips made by motor vehicle. Further longitudinal and intervention research is required to assess generalisability of these findings . PMID- 30282647 TI - The socially mediated recovery of a fearful fish paired with periodically replaced calm models. AB - Social learning is an important mechanism for acquiring knowledge about environmental risk. However, little work has explored the learning of safety and how such learning outcomes are shaped by the social environment. Here, we exposed minnows, Pimephales promelas, to a high-risk environment to induce behavioural responses associated with fear (e.g. neophobia). We then used the presence of calm conspecific models (low-risk individuals) to weaken these responses. When observers (individuals from the high-risk environment) and models were paired consistently in a one-on-one setting, the observers showed no recovery (i.e. no weakening of the fear responses), and instead the models indirectly acquired those responses (i.e. a socially transmitted state of fear). However, observers paired with models that were periodically replaced with new calm models showed a significant recovery, and each new model showed diminished socially transmitted fear. We argue that our understanding of predation-related fear and social information transfer can prove fruitful in understanding problems with fear and stress across animal taxa, including among humans who experience post-traumatic stress and secondary trauma. Our findings indicate that the periodic replacement of models can promote fear recovery in observers and reduce socially transmitted fear in models. PMID- 30282649 TI - Spatial heterogeneity contributes more to portfolio effects than species variability in bottom-associated marine fishes. AB - Variance of community abundance will be reduced relative to its theoretical maximum whenever population densities fluctuate asynchronously. Fishing communities and mobile predators can switch among fish species and/or fishing locations with asynchronous dynamics, thereby buffering against variable resource densities (termed 'portfolio effects', PEs). However, whether variation among species or locations represent the dominant contributor to PE remains relatively unexplored. Here, we apply a spatio-temporal model to multidecadal time series (1982-2015) for 20 bottom-associated fishes in seven marine ecosystems. For each ecosystem, we compute the reduction in variance over time in total biomass relative to its theoretical maximum if species and locations were perfectly correlated (total PE). We also compute the reduction in variance due to asynchrony among species at each location (species PE) or the reduction due to asynchrony among locations for each species (spatial PE). We specifically compute total, species and spatial PE in 10-year moving windows to detect changes over time. Our analyses revealed that spatial PE are stronger than species PE in six of seven ecosystems, and that ecosystems where species PE is constant over time can exhibit shifts in locations that strongly contribute to PE. We therefore recommend that spatial and total PE be monitored as ecosystem indicators representing risk exposure for human and natural consumers. PMID- 30282648 TI - Molecular archaeoparasitology identifies cultural changes in the Medieval Hanseatic trading centre of Lubeck. AB - Throughout history, humans have been afflicted by parasitic worms, and eggs are readily detected in archaeological deposits. This study integrated parasitological and ancient DNA methods with a large sample set dating between Neolithic and Early Modern periods to explore the utility of molecular archaeoparasitology as a new approach to study the past. Molecular analyses provided unequivocal species-level parasite identification and revealed location specific epidemiological signatures. Faecal-oral transmitted nematodes (Ascaris lumbricoides and Trichuris trichiura) were ubiquitous across time and space. By contrast, high numbers of food-associated cestodes (Diphyllobothrium latum and Taenia saginata) were restricted to medieval Lubeck. The presence of these cestodes and changes in their prevalence at approximately 1300 CE indicate substantial alterations in diet or parasite availability. Trichuris trichiura ITS 1 sequences grouped into two clades; one ubiquitous and one restricted to medieval Lubeck and Bristol. The high sequence diversity of T.tITS-1 detected in Lubeck is consistent with its importance as a Hanseatic trading centre. Collectively, these results introduce molecular archaeoparasitology as an artefact-independent source of historical evidence. PMID- 30282650 TI - Comparative demography elucidates the longevity of parasitic and symbiotic relationships. AB - Parasitic and symbiotic relationships govern vast nutrient and energy flows, yet controversy surrounds their longevity. Enduring relationships may engender parallel phylogenies among hosts and parasites, but so may ephemeral relationships when parasites colonize related hosts. An understanding of whether symbiont and host populations have grown and contracted in concert would be useful when considering the temporal durability of these relationships. Here, we devised methods to compare demographic histories derived from genomic data. We compared the historical growth of the agent of severe human malaria, Plasmodium falciparum, and its mosquito vector, Anopheles gambiae, to human and primate histories, thereby discerning long-term parallels and anthropogenic population explosions. The growth history of Trichinella spiralis, a zoonotic parasite disseminated by swine, proved regionally specific, paralleling distinctive growth histories for wild boar in Asia and Europe. Parallel histories were inferred for an anemone and its algal symbiont (Exaiptasia pallida and Symbiodinium minutum). Concerted growth in potatoes and the agent of potato blight (Solanum tuberosum and Phytophthora infestans) did not commence until the age of potato domestication. Through these examples, we illustrate the utility of comparative historical demography as a new exploratory tool by which to interrogate the origins and durability of myriad ecological relationships. To facilitate future use of this approach, we introduce a tool called C-PSMC to align and evaluate the similarity of demographic history curves. PMID- 30282651 TI - Carrying a selfish genetic element predicts increased migration propensity in free-living wild house mice. AB - Life is built on cooperation between genes, which makes it vulnerable to parasitism. Selfish genetic elements that exploit this cooperation can achieve large fitness gains by increasing their transmission relative to the rest of the genome. This leads to counter-adaptations that generate unique selection pressures on the selfish genetic element. This arms race is similar to host parasite coevolution, as some multi-host parasites alter the host's behaviour to increase the chance of transmission to the next host. Here, we ask if, similarly to these parasites, a selfish genetic element in house mice, the t haplotype, also manipulates host behaviour, specifically the host's migration propensity. Variants of the t that manipulate migration propensity could increase in fitness in a meta-population. We show that juvenile mice carrying the t haplotype were more likely to emigrate from and were more often found as migrants within a long term free-living house mouse population. This result may have applied relevance as the t has been proposed as a basis for artificial gene drive systems for use in population control. PMID- 30282652 TI - Female control over multiple matings increases the opportunity for postcopulatory sexual selection. AB - It is widely acknowledged that in most species sexual selection continues after mating. Although it is generally accepted that females play an important role in generating paternity biases (i.e. cryptic female choice, CFC), we lack a quantitative understanding of the relative importance of female-controlled processes in influencing variance in male reproductive fitness. Here, we address this question experimentally using the guppy Poecilia reticulata, a polyandrous fish in which pre- and postcopulatory sexual selection jointly determine male reproductive fitness. We used a paired design to quantify patterns of paternity for pairs of rival males across two mating contexts, one in which the female retained full control over double (natural) matings and one where sperm from the same two males were artificially inseminated into the female. We then compared the relative paternity share for a given pair of males across both contexts, enabling us to test the key prediction that patterns of paternity will depend on the extent to which females retain behavioural control over matings. As predicted, we found stronger paternity biases when females retained full control over mating compared with when artificial insemination (AI) was used. Concomitantly, we show that the opportunity for postcopulatory sexual selection (standardized variance in male reproductive success) was greater when females retained control over double matings compared with when AI was used. Finally, we show that the paternity success of individual males exhibited higher repeatability across successive brood cycles when females retained behavioural control of matings compared with when AI was used. Collectively, these findings underscore the critical role that females play in determining the outcome of sexual selection and to our knowledge provide the first experimental evidence that behaviourally moderated components of CFC increase the opportunity for sexual selection. PMID- 30282653 TI - Expression of a novel surfactant protein gene is associated with sites of extrapulmonary respiration in a lungless salamander. AB - Numerous physiological and morphological adaptations were achieved during the transition to lungless respiration that accompanied evolutionary lung loss in plethodontid salamanders, including those that enable efficient gas exchange across extrapulmonary tissue. However, the molecular basis of these adaptations is unknown. Here, we show that lungless salamanders express in the larval integument and the adult buccopharynx-principal sites of respiratory gas exchange in these species-a novel paralogue of the gene surfactant-associated protein C (SFTPC), which is a critical component of pulmonary surfactant expressed exclusively in the lung in other vertebrates. The paralogous gene appears to be found only in salamanders, but, similar to SFTPC, in lunged salamanders it is expressed only in the lung. This heterotopic gene expression, combined with predictions from structural modelling and respiratory tissue ultrastructure, suggests that lungless salamanders may produce pulmonary surfactant-like secretions outside the lungs and that the novel paralogue of SFTPC might facilitate extrapulmonary respiration in the absence of lungs. Heterotopic expression of the SFTPC paralogue may have contributed to the remarkable evolutionary radiation of lungless salamanders, which account for more than two thirds of urodele species alive today. PMID- 30282654 TI - Rhythmic motor behaviour influences perception of visual time. AB - Temporal processing is fundamental for an accurate synchronization between motor behaviour and sensory processing. Here, we investigate how motor timing during rhythmic tapping influences perception of visual time. Participants listen to a sequence of four auditory tones played at 1 Hz and continue the sequence (without auditory stimulation) by tapping four times with their finger. During finger tapping, they are presented with an empty visual interval and are asked to judge its length compared to a previously internalized interval of 150 ms. The visual temporal estimates show non-monotonic changes locked to the finger tapping: perceived time is maximally expanded at halftime between the two consecutive finger taps, and maximally compressed near tap onsets. Importantly, the temporal dynamics of the perceptual time distortion scales linearly with the timing of the motor tapping, with maximal expansion always being anchored to the centre of the inter-tap interval. These results reveal an intrinsic coupling between distortion of perceptual time and production of self-timed motor rhythms, suggesting the existence of a timing mechanism that keeps perception and action accurately synchronized. PMID- 30282655 TI - Delayed trait development and the convergent evolution of shell kinesis in turtles. AB - Understanding developmental processes is foundational to clarifying the mechanisms by which convergent evolution occurs. Here, we show how a key convergently evolving trait is slowly 'acquired' in growing turtles. Many functionally relevant traits emerge late in turtle ontogeny, owing to design constraints imposed by the shell. We investigated this trend by examining derived patterns of shell formation associated with the multiple (at least 8) origins of shell kinesis in small-bodied turtles. Using box turtles as a model, we demonstrate that the flexible hinge joint required for shell kinesis differentiates gradually and via extensive repatterning of shell tissue. Disproportionate changes in shell shape and size substantiate that this transformation is a delayed ontogenetic response (3-5 years post-hatching) to structural alterations that arise in embryogenesis. These findings exemplify that the translation of genotype to phenotype may reach far beyond embryonic life stages. Thus, the temporal scope for developmental origins of adaptive morphological change might be broader than generally understood. We propose that delayed trait differentiation via tissue repatterning might facilitate phenotypic diversification and innovation that otherwise would not arise due to developmental constraints. PMID- 30282656 TI - A non-coding region near Follistatin controls head colour polymorphism in the Gouldian finch. AB - Discrete colour morphs coexisting within a single population are common in nature. In a broad range of organisms, sympatric colour morphs often display major differences in other traits, including morphology, physiology or behaviour. Despite the repeated occurrence of this phenomenon, our understanding of the genetics that underlie multi-trait differences and the factors that promote the long-term maintenance of phenotypic variability within a freely interbreeding population are incomplete. Here, we investigated the genetic basis of red and black head colour in the Gouldian finch (Erythrura gouldiae), a classic polymorphic system in which naturally occurring colour morphs also display differences in aggressivity and reproductive success. We show that the candidate locus is a small (approx. 70 kb) non-coding region mapping to the Z chromosome near the Follistatin (FST) gene. Unlike recent findings in other systems where phenotypic morphs are explained by large inversions containing hundreds of genes (so-called supergenes), we did not identify any structural rearrangements between the two haplotypes using linked-read sequencing technology. Nucleotide divergence between the red and black alleles was high when compared to the remainder of the Z chromosome, consistent with their maintenance as balanced polymorphisms over several million years. Our results illustrate how pleiotropic phenotypes can arise from simple genetic variation, probably regulatory in nature. PMID- 30282657 TI - Adaptive periodicity in the infectivity of malaria gametocytes to mosquitoes. AB - Daily rhythms in behaviour, physiology and molecular processes are expected to enable organisms to appropriately schedule activities according to consequences of the daily rotation of the Earth. For parasites, this includes capitalizing on periodicity in transmission opportunities and for hosts/vectors, this may select for rhythms in immune defence. We examine rhythms in the density and infectivity of transmission forms (gametocytes) of rodent malaria parasites in the host's blood, parasite development inside mosquito vectors and potential for onwards transmission. Furthermore, we simultaneously test whether mosquitoes exhibit rhythms in susceptibility. We reveal that at night, gametocytes are twice as infective, despite being less numerous in the blood. Enhanced infectiousness at night interacts with mosquito rhythms to increase sporozoite burdens fourfold when mosquitoes feed during their rest phase. Thus, changes in mosquito biting time (owing to bed nets) may render gametocytes less infective, but this is compensated for by the greater mosquito susceptibility. PMID- 30282658 TI - Roles of glycosaminoglycans as regulators of ligand/receptor complexes. AB - Glycosaminoglycans (GAGs) play a widespread role in embryonic development, as deletion of enzymes that contribute to GAG synthesis lead to deficiencies in cell migration and tissue modelling. Despite the biochemical and structural characterization of individual protein/GAG interactions, there is no concept available that links the molecular mechanisms of GAG/protein engagements to tissue development. Here, we focus on the role of GAG polymers in mediating interactions between cell surface receptors and their ligands. We categorize several switches that lead to ligand activation, inhibition, selection and addition, based on recent structural studies of select receptor/ligand complexes. Based on these principles, we propose that individual GAG polymers may affect several receptor pathways in parallel, orchestrating a cellular response to an environmental cue. We believe that it is worthwhile to study the role of GAGs as molecular switches, as this may lead to novel drug candidates to target processes such as angiogenesis, neuroregeneration and tumour metastasis. PMID- 30282659 TI - Intracellular RNA-tracking methods. AB - RNA tracking allows researchers to visualize RNA molecules in cells and tissues, providing important spatio-temporal information regarding RNA dynamics and function. Methods such as fluorescent in situ hybridization (FISH) and molecular beacons rely on complementary oligonucleotides to label and view endogenous transcripts. Other methods create artificial chimeric transcripts coupled with bacteriophage-derived coat proteins (e.g. MS2, lambdaN) to tag molecules in live cells. In other approaches, endogenous RNAs are recognized by complementary RNAs complexed with noncatalytic Cas proteins. Each technique has its own set of strengths and limitations that must be considered when planning an experiment. Here, we discuss the mechanisms, advantages, and weaknesses of in situ hybridization, molecular beacons, MS2 tagging and Cas-derived systems, as well as how RNA tracking can be employed to study various aspects of molecular biology. PMID- 30282662 TI - Mind-body therapies: an intervention to reduce work-related stress in veterinary academia. AB - Studies investigating perceived stress and mindfulness awareness support mind body therapy (MBT) effectiveness in reducing stress and anxiety and, thus, has potential to decrease work-related stress. A pre/postexperimental design involved 30 faculty and staff working at Ross University School of Veterinary Medicine, Saint Kitts and Nevis, who experienced a two-day MBT intervention programme. An additional 16 faculty and staff not involved in MBT who went about their daily work schedules served as contemporary controls. Demographics, Perceived Stress Scale 10 (PSS-10), Mindful Attention Awareness Scale (MAAS), 16 Personality Factor (16PF) Openness to Change subscale and saliva cortisol concentrations were analysed. Control participants reported significantly perceived less stress (PSS 10: M=13; sd=1.4) than intervention participants (M=20; sd=6.6) during pretest. However, at post-test the intervention group reported a significant decrease in perceived stress (M=11; sd=6.0). MAAS pretest results indicated the intervention group displayed a lower average score (M=54; sd=15.3) than control participants (M=68; sd=2.0). Post-MAAS intervention scores showed improvements in mindfulness (M=63; sd=15.3). Correlations between the 16PF Openness to Change subscale and MAAS were r=0.03 and r=-0.17 for the intervention and control groups, respectively. Mean concentrations of saliva cortisol indicated a larger and significant decline in cortisol for the intervention group both during day 1 (P=0.0001) and day 2 (P=0.0008). In conclusion, these preliminary results provide support that MBTs in veterinary academia can improve psychological and physiological aspects of personal wellbeing. PMID- 30282660 TI - Wnt signalling in the development of axon, dendrites and synapses. AB - Wnts are a highly conserved family of secreted glycoproteins that play essential roles in the morphogenesis and body patterning during the development of metazoan species. In recent years, mounting evidence has revealed important functions of Wnt signalling in diverse aspects of neural development, including neuronal polarization, guidance and branching of the axon and dendrites, as well as synapse formation and its structural remodelling. In contrast to Wnt signalling in cell proliferation and differentiation, which mostly acts through beta-catenin dependent pathways, Wnts engage a diverse array of non-transcriptional cascades in neuronal development, such as the planar cell polarity, cytoskeletal or calcium signalling pathways. In this review, we summarize recent advances in the mechanisms of Wnt signalling in the development of axon, dendrite and synapse formation. PMID- 30282664 TI - Safety and effectiveness of albuterol solutions with and without benzalkonium chloride when administered by continuous nebulization. AB - PURPOSE: The results of a study to determine if rates of poor response differ in patients receiving continuous nebulized albuterol (CNA) therapy with or without the preservative benzalkonium chloride are presented. METHODS: A retrospective analysis of the records of all patients who received CNA therapy at a large academic medical center from July 2015 to January 2016 was conducted. Data from patient evaluations performed before and after a change to benzalkonium chloride containing albuterol were collected. The primary outcome was the rate of poor patient response, defined as a composite endpoint. Secondary outcomes included duration of therapy, dosing requirements, and duration of supplemental oxygen therapy. RESULTS: There was no significant difference in rates of poor response between patients exposed (n = 80) and patients not exposed (n = 48) to benzalkonium chloride (16% and 17%, respectively; p = 0.95). The cohort not exposed to benzalkonium chloride had a median CNA duration of 7.0 hours, as compared with 10.5 hours for the cohort exposed to benzalkonium chloride, but this difference was not significant (p = 0.19). There were no significant differences between the benzalkonium chloride-exposed and nonexposed cohorts in the maximum dosing requirement (12.6 mg/hr versus 12.8 mg/hr, p = 0.89) or median duration of supplemental oxygen use (27.5 hours versus 16.5 hours, p = 0.77). CONCLUSION: A study of hospitalized patients receiving CNA detected no significant difference in the frequency of poor response to therapy between groups receiving benzalkonium chloride-free versus benzalkonium chloride containing albuterol products. PMID- 30282663 TI - Primary care collaborative practice in quality improvement: Description of an interprofessional curriculum. AB - PURPOSE: An innovative quality improvement (QI)-focused interprofessional training curriculum for pharmacy residents and other healthcare trainees is described. SUMMARY: Effective interprofessional collaboration and the ability to carry out QI initiatives are important skills for all healthcare trainees to develop when they are in training. To cultivate those skills, in 2011 a Veterans Affairs medical center in Idaho implemented a unique yearlong interprofessional curriculum for healthcare trainees, including postgraduate year 1 (PGY1) and postgraduate year 2 (PGY2) pharmacy residents, physician trainees in internal medicine, nurses, and psychologists. The curriculum has both didactic and experiential components. After attending a series of 1-hour workshops early in the academic year, trainees are assigned to interprofessional teams and work for the remainder of the year to complete QI projects. Over 100 trainees have participated in the interprofessional QI curriculum, with the majority of trainee projects based in the primary care setting. Pharmacy residents were involved in 62% of the projects completed in the 6 academic years ending with the 2016-17 year. CONCLUSION: Establishing an interprofessional QI curriculum allowed pharmacy residents in PGY1 and PGY2 programs to collaborate with other members of the healthcare team. Benefits include QI skills development, a greater understanding of QI initiatives at the institution, stronger relationships with other healthcare trainees and mentors, and improvements to patient care and safety and facility performance. PMID- 30282665 TI - Development of an operational productivity tool within a cancer treatment center pharmacy. AB - PURPOSE: The development and implementation of an operational productivity tool in an academic cancer treatment center are described. SUMMARY: Based on the increasing complexity of care delivery within the oncology setting, solutions were explored within Cleveland Clinic pharmacy's productivity model. Data were electronically captured based on orders processed through the outpatient oncology setting, including hazardous and nonhazardous medications. Based on current workflow, inpatient and outpatient orders were reviewed in productivity metrics. The metric defining the variability of the workload itself was weighted dispense type as it was the best representation of a mixed-skill workflow. After conducting workflow process mapping, discrete measurable steps were assessed and evaluated daily. Operational components of interest included pharmacist verification activities and technician compounding activities. Historical production data were sampled for assigning relative value units (RVUs) respective to time to normalize workload into a common unit (i.e., 1 hour) and to relate work demand in a highly variable setting. RVUs were assigned and delineated by cognitive and distributive activities for pharmacists and technicians, respectively. The Cleveland Clinic department of pharmacy developed a productivity tool to retrospectively measure workload involving time to review, verify, reconstitute, admix, and deliver chemotherapeutic agents. The weighting of each medication allowed for precise and meaningful evaluation of productivity. With RVUs assigned to 2 years of operational metrics, there now exists an opportunity to monitor performance trends within the cancer treatment center pharmacy. The data are readily retrievable within the electronic health record. CONCLUSION: The productivity data provided precise information to assess trends in operations within the pharmacy of an outpatient cancer treatment center. PMID- 30282661 TI - Into the breach: how cells cope with wounds. AB - Repair of wounds to individual cells is crucial for organisms to survive daily physiological or environmental stresses, as well as pathogen assaults, which disrupt the plasma membrane. Sensing wounds, resealing membranes, closing wounds and remodelling plasma membrane/cortical cytoskeleton are four major steps that are essential to return cells to their pre-wounded states. This process relies on dynamic changes of the membrane/cytoskeleton that are indispensable for carrying out the repairs within tens of minutes. Studies from different cell wound repair models over the last two decades have revealed that the molecular mechanisms of single cell wound repair are very diverse and dependent on wound type, size, and/or species. Interestingly, different repair models have been shown to use similar proteins to achieve the same end result, albeit sometimes by distinctive mechanisms. Recent studies using cutting edge microscopy and molecular techniques are shedding new light on the molecular mechanisms during cellular wound repair. Here, we describe what is currently known about the mechanisms underlying this repair process. In addition, we discuss how the study of cellular wound repair-a powerful and inducible model-can contribute to our understanding of other fundamental biological processes such as cytokinesis, cell migration, cancer metastasis and human diseases.

AB - Antiphospholipid syndrome, also known as 'Hughes Syndrome', is an autoimmune disease characterised by a set of clinical manifestations, almost all of which are direct or indirect sequelae of a hypercoagulable state involving the venous, and to a lesser extent the arterial vasculature. The incidence and prevalence of antiphospholipid syndrome are estimated at approximately 5 de novo cases per 100 000 per year and 40-50 cases per 100 000 individuals, respectively. The clinical spectrum of antiphospholipid syndrome involves haematological (thrombocytopaenia, venous thrombosis), obstetrical (recurrent pregnancy loss), neurological (stroke, transient ischaemic attack, migraine, seizures, cognitive dysfunction, chorea, transverse myelitis, multiple sclerosis), cardiovascular (cardiac valve disease), dermatological (livedo reticularis and racemosa, skin ulceration and necrosis), renal (glomerulonephritis, renal thrombotic microangiopathy) and orthopaedic (avascular necrosis of bones, non-traumatic fractures) manifestations, among others. In addition to the classical antiphospholipid antibodies, namely anticardiolipin antibodies and lupus anticoagulant, new autoantibodies and antibody complexes of different immunoglobulin subtypes (IgA, IgG, IgM) are now recognised as significant contributors to the pathogenesis of antiphospholipid syndrome. Anticoagulation remains the cornerstone in the management of antiphospholipid syndrome; nevertheless, new drugs and therapeutic strategies are being tested, and some have been found effective for the primary and secondary thromboprophylaxis in antiphospholipid syndrome.

PMID- 30282670 TI - Etanercept in patients with inflammatory hand osteoarthritis (EHOA): a multicentre, randomised, double-blind, placebo-controlled trial. AB - OBJECTIVE: Hand osteoarthritis is a prevalent disease with limited treatment options. Since joint inflammation is often present, we investigated tumour necrosis factor (TNF) as treatment target in patients with proven joint inflammation in a proof-of-concept study. METHODS: This 1-year, double-blind, randomised, multicentre trial (NTR1192) enrolled patients with symptomatic erosive inflammatory hand osteoarthritis. Patients flaring after non-steroidal anti-inflammatory drug washout were randomised to etanercept (24 weeks 50 mg/week, thereafter 25 mg/week) or placebo. The primary outcome was Visual Analogue Scale (VAS) pain at 24 weeks. Secondary outcomes included clinical and imaging outcomes (radiographs scored using Ghent University Scoring System (GUSS, n=54) and MRIs (n=20)). RESULTS: Of 90 patients randomised to etanercept (n=45) or placebo (n=45), respectively, 12 and 10 discontinued prematurely. More patients on placebo discontinued due to inefficacy (6 vs 3), but fewer due to adverse effects (1 vs 6). The mean between-group difference (MD) in VAS pain was not statistically significantly different (-5.7 (95% CI -15.9 to 4.5), p=0.27 at 24 weeks; - 8.5 (95% CI -18.6 to 1.6), p=0.10 at 1 year; favouring etanercept). In prespecified per-protocol analyses of completers with pain and inflammation at baseline (n=61), MD was -11.8 (95% CI -23.0 to -0.5) (p=0.04) at 1 year. Etanercept-treated joints showed more radiographic remodelling (delta GUSS: MD 2.9 (95% CI 0.5 to 5.4), p=0.02) and less MRI bone marrow lesions (MD -0.22 (95% CI -0.35 to -0.09), p = 0.001); this was more pronounced in joints with baseline inflammation. CONCLUSION: Anti-TNF did not relieve pain effectively after 24 weeks in erosive osteoarthritis. Small subgroup analyses showed a signal for effects on subchondral bone in actively inflamed joints, but future studies to confirm this are warranted. PMID- 30282671 TI - Somatic Mutations and Immune Alternation in Rectal Cancer Following Neoadjuvant Chemoradiotherapy. AB - Checkpoint blockade therapy triggers tumor-specific immune responses in a variety of cancer types. We presumed that rectal cancer patients could have become sensitive to immunotherapy after receiving neoadjuvant chemoradiotherapy (nCRT). In this study, we report immune alternation in post-nCRT patients compared with pretreatment conditions from gene-expression omnibus (GEO) data. Whole-exome sequencing of 14 locally advanced rectal cancer (LARC) patient samples showed that nCRT induced new mutations compared with the paired pretreatment biopsies, evidenced by appearance of a neoantigen landscape. An association was identified between mutation burden and enrichment of immune activation-related pathways. Animal experiment results further demonstrated that radiotherapy enhanced the efficacy of anti-PD-1. Mutation burden and the neoantigens of LARC patients were associated with response to nCRT. The mRNA expression profiling of 66 pretreatment biopsy samples from LARC patients showed that immune activation related pathways were enriched in response to nCRT. PD-L1 expression was negatively correlated with disease-free survival in the CD8-low expression patient group who received nCRT in a cohort of 296 samples. Thus, nCRT was able to alter immune function in LARC patients, which may be associated with the appearance of neoantigens. Neoantigens could make rectal cancer patients potential candidates to receive checkpoint blockade immunotherapy, and mutation burden could be a useful biomarker to stratify patients into responding and nonresponding groups for immunotherapy. Cancer Immunol Res; 6(11); 1401-16. (c)2018 AACR. PMID- 30282672 TI - PD-L1 Mediates Dysfunction in Activated PD-1+ NK Cells in Head and Neck Cancer Patients. AB - Inhibitory immune-checkpoint receptors (ICRs), including programmed death 1 (PD 1), have been characterized as exhaustion markers on T cells that infiltrate the tumor microenvironment (TME) of many cancer types, including head and neck cancer (HNC). However, expression and function of ICRs, including PD-1, on natural killer (NK) cells remains less defined. NK cells are innate immune effector cells that lyse epidermal growth factor receptor-overexpressing HNC cells via cetuximab mediated antibody-dependent cytotoxicity. Cetuximab is clinically effective but only in 10% to 15% of patients. Therefore, it is necessary to investigate how immunomodulation with cetuximab or PD-1 blockade might enhance NK cell responses in the TME and improve monoclonal antibody therapeutic efficacy. We observed that expression of PD-1 on NK cells marks an activated phenotype, which was suppressed only after binding programmed death ligand-1 (PD-L1). HNC patients who exhibit higher circulating PD-1+ NK cells associate with better clinical outcome, and these cells are enriched in the TME. Cetuximab-mediated NK cell activation increased PD-1 expression on NK cells in vitro, which was confirmed in vivo in a prospective neoadjuvant cetuximab trial. In contrast, PD-L1 ligation of PD-1+ NK cells diminished their activation status, whereas PD-1 blockade increased cetuximab-mediated NK cell activation and cytotoxicity, but only against HNC targets with high PD-L1 expression. Therefore, blocking the PD-1-PD-L1 axis may be a useful strategy to reverse immune evasion of HNC tumors with high PD-L1 expression during cetuximab therapy by reversing NK cell dysfunction. PMID- 30282673 TI - Lysis Timer: a new sensitive tool to diagnose hyperfibrinolysis in liver transplantation. AB - AIMS: Diagnosis of hyperfibrinolysis in orthotopic liver transplantation (OLT) remains challenging. Euglobulin clot lysis time (ECLT) is not adapted to clinical situations. ROTEM is specific but seldom sensitive to hyperfibrinolysis. The Lysis Timer assesses 'Global Fibrinolytic Capacity' in citrated plasma (GFC/LT). GFC/LT associates reagents for in vitro triggering of the clot (thrombin and calcium) and its lysis (tissue-plasminogenactivator (t-PA)), turbidity signal acquisition by the Lysis Timer, and dedicated software converting the digital signal into an optical curve. A visual check of the curves was systematic to ascertain the lysis time values calculated by the software. The primary aim of this prospective observational study was to evaluate the ability of GFC/LT to recognise hyperfibrinolysis during OLT. The secondary aim was to compare its results with ROTEM maximum lysis (EXTEM ML) and with standard laboratory tests. METHODS: Thirty consecutive adult patients undergoing OLT were included (NCT03012633). Standard laboratory tests, ROTEM, GFC/LT, ECLT and fibrinolysis parameters were assayed at five sample times. RESULTS: GFC/LT was correlated with ECLT, plasmin activator inhibitor 1 antigen and activity and t-PA activity (r=0.490, 0.681, 0.643 and -0.359, respectively). Hyperfibrinolysis was defined as ECLT <=60 min. Receiver operating characteristic curve analysis showed that GFC/LT with a threshold of 31 min detected hyperfibrinolysis with a sensitivity of 0.88 (95% CI 0.73 to 0.96), a specificity of 0.68 (95% CI 0.56 to 0.78) and an area under the curve (AUC) of 0.85 (95% CI 0.74 to 0.94). EXTEM ML >12% did not detect hyperfibrinolysis (sensitivity 0.38 (95% CI 0.24 to 0.55), specificity 0.95 (95% CI 0.86 to 0.99) and AUC 0.60 (95% CI 0.46 to 0.75)). CONCLUSIONS: GFC/LT recognised hyperfibrinolysis during OLT with a significant agreement with the other tests of fibrinolysis. TRIAL REGISTRATION NUMBER: NCT03012633. PMID- 30282674 TI - Physiological-based cord clamping in preterm infants using a new purpose-built resuscitation table: a feasibility study. AB - OBJECTIVE: Physiological-based cord clamping (PBCC) led to a more stable cardiovascular adaptation and better oxygenation in preterm lambs, but in preterm infants, this approach has been challenging. Our aim was to assess the feasibility of PBCC, including patterns of oxygen saturation (SpO2) and heart rate (HR) during stabilisation in preterm infants using a new purpose-built resuscitation table. DESIGN: Observational study. SETTING: Tertiary referral centre, Leiden University Medical Centre, The Netherlands. PATIENTS: Infants born below 35 weeks' gestational age. INTERVENTIONS: Infants were stabilised on a new purpose-built resuscitation table (Concord), provided with standard equipment needed for stabilisation. Cord clamping was performed when the infant was stable (HR >100 bpm, spontaneous breathing on continuous positive airway pressure with tidal volumes >4 mL/kg, SpO2 >=25th percentile and fraction of inspired oxygen (FiO2) <0.4). RESULTS: Thirty-seven preterm infants were included; mean (SD) gestational age of 30.9 (2.4) weeks, birth weight 1580 (519) g. PBCC was successful in 33 infants (89.2%) and resulted in median (IQR) cord clamping time of 4:23 (3:00-5:11) min after birth. There were no maternal or neonatal adverse events. In 26/37 infants, measurements were adequate for analysis. HR was 113 (81 143) and 144 (129-155) bpm at 1 min and 5 min after birth. SpO2 levels were 58%(49%-60%) and 91%(80%-96%)%), while median FiO2 given was 0.30 (0.30-0.31) and 0.31 (0.25-0.97), respectively. CONCLUSION: PBCC in preterm infants using the Concord is feasible. HR remained stable, and SpO2 quickly increased with low levels of oxygen supply. TRIAL REGISTRATION NUMBER: NTR6095, results. PMID- 30282675 TI - Making doctors better.

PMID- 30282676 TI - Can the completeness of radiological cancer staging reports be improved using proforma reporting? A prospective multicentre non-blinded interventional study across 21 centres in the UK. AB - OBJECTIVES: Following a diagnosis of cancer, the detailed assessment of prognostic stage by radiology is a crucial determinant of initial therapeutic strategy offered to patients. Pretherapeutic stage by imaging is known to be inconsistently documented. We tested whether the completeness of cancer staging radiology reports could be improved through a nationally introduced pilot of proforma-based reporting for a selection of six common cancers. DESIGN: Prospective interventional study comparing the completeness of radiology cancer staging reports before and after the introduction of proforma reporting. SETTING: Twenty-one UK National Health Service hospitals. PARTICIPANTS: 1283 cancer staging radiology reports were submitted. MAIN OUTCOME MEASURES: Radiology staging reports across the six cancers types were evaluated before and after the implementation of proforma-based reporting. Report completeness was assessed using scoring forms listing the presence or absence of predetermined key staging data. Qualitative data regarding proforma implementation and usefulness were collected from questionnaires provided to radiologists and end-users. RESULTS: Electronic proforma-based reporting was successfully implemented in 15 of the 21 centres during the evaluation period. A total of 787 preproforma and 496 postproforma staging reports were evaluated. In the preproforma group, only 48.7% (5586/11 470) of key staging items were present compared with 87.3% (6043/6920) in the postproforma group. Thus, the introduction of proforma reporting produced a 78% improvement in staging completeness . This increase was seen across all cancer types and centres. The majority of participants found proforma reporting improved cancer reporting quality for their clinical practice . CONCLUSION: The implementation of proforma reporting results in a significant improvement in the completeness of cancer staging reports. Proforma-based assessment of cancer stage enables objective comparisons of patient outcomes across centres. It should therefore become an auditable quality standard for cancer care. PMID- 30282677 TI - Safety and efficacy of self-administered inhaled loxapine (ADASUVE) in agitated patients outside the hospital setting: protocol for a phase IV, single-arm, open label trial. AB - INTRODUCTION: There is a need for fast-acting, non-injection antiagitation treatments that are well tolerated and can be used outside of healthcare facilities. In phase II/III trials, an inhaled formulation of loxapine (ADASUVE(r)), a well-established, first-generation antipsychotic agent, provided rapid control of mild to moderate agitation in the hospital setting. The present study was designed to investigate the safety and efficacy of inhaled loxapine when self-administered outside the hospital setting. METHODS AND ANALYSIS: This phase IV, multicentre, single-arm, open-label clinical trial is being conducted in five countries in Europe: Spain, Germany, Norway, Romania and Austria. The aim is to include approximately 500 patients with schizophrenia or bipolar disorder who previously received and responded well to inhaled loxapine in the hospital setting. Eligible patients will be followed up for 6 months from baseline. They will be given a 10 mg dose of inhaled loxapine to self-administer outside the hospital setting to treat an agitation episode, should one occur. Patients will also be given a short-acting beta-agonist bronchodilator for treatment of possible severe respiratory side effects. The primary endpoint is incidence of serious adverse events (AEs) and respiratory AEs of special interest related to use of inhaled loxapine outside the hospital setting. Secondary endpoints include incidence of other AEs, Clinical Global Impression-Improvement scores up to 2 hours after self-administration of inhaled loxapine, time to improvement of agitation, patient satisfaction with treatment, treatment outcomes according to agitation severity and concordance between the patient (or a family member/caregiver) and the physician in scoring of agitation severity and the decision to self-administer inhaled loxapine. ETHICS AND DISSEMINATION: The protocol received ethics committee approval in the participating countries between January and August 2016. The results of this study will be disseminated through one or more scientific papers. TRIAL REGISTRATION NUMBER: EudraCT2015 003331-36; NCT02525991; Pre-results. PMID- 30282678 TI - Limited implementation of the framework convention on tobacco control's tobacco tax provision: global comparison. AB - OBJECTIVE: To quantify changes in tobacco tax rates and cigarette affordability after countries ratified the WHO Framework Convention on Tobacco Control (FCTC) using with the WHO MPOWER standards. METHODS: We used logistic regression to assess the association of FCTC ratification with adoption of at least 50% and 75% (high) of retail price tobacco tax rates for the most sold brands in countries, accounting for years since ratification and other covariates. We also compared cigarette affordability in 2014 with 1999. RESULTS: By 2014, 44% of high-income countries had taxes above 75% of retail value compared with 18% in 1998/1999. In 15 years, 69 countries increased the tobacco tax rate, 33 decreased it and one had the same tax rate. FCTC ratification was not associated with implementing high tobacco taxes. More fragile countries in terms of security, political, economic and social development were less likely to have at least 50% and 75% tobacco tax rates in 2014 compared with 1999. The higher the cigarette prices in 1999 the less likely the countries were to have at least 75% tobacco tax rates in 2014. However, cigarettes were less affordable in 2014 than in 1999 in countries that had ratified FCTC earlier. CONCLUSIONS: Despite widespread FCTC ratification, implementing higher tobacco taxes remains incomplete. Guidelines for FCTC Article 6 implementation should assign definite targets for tobacco taxes and for implementation of a tax escalator that gradually increases taxes to match rising income levels. Fragile countries are less likely to have high tobacco taxes and less affordable cigarettes. The tobacco control community should intensify efforts to help fragile countries improve performance in FCTC implementation both through strengthening their administrative and technical capacity and through supporting basic functions of government. PMID- 30282679 TI - Dynamics and Determinants of HPV Infection: The Michigan HPV and Oropharyngeal Cancer (M-HOC) Study. AB - INTRODUCTION: Human papillomavirus (HPV) is the primary cause of cervical and other anogenital cancers and is also associated with head and neck cancers. Incidence of HPV-related oropharyngeal squamous cell cancers (OPSCCs) is increasing, and HPV-related OPSCCs have surpassed cervical cancer as the most common HPV-related cancer in the USA. Given the multisite nature of HPV, there is strong interest in collecting data from both genital and oral sites, as well as associated data on social and sexual behaviours. The overarching goal of this study is to evaluate patterns of oral HPV infection incidence, clearance and persistence and their relationship to sexual behaviour history. METHODS AND ANALYSIS: Participants are recruited from two populations: college students at a large public university and general population from the surrounding area. At the first study visit, participants complete a detailed sexual history, health and behaviour questionnaire. Follow-up visits occur every 3-4 months over 3 years, when participants complete an abbreviated questionnaire. All participants provide a saliva sample at each visit, and eligible participants may provide a cervicovaginal self-swab. Genetic material isolated from specimens is tested for 15 high-risk and 3 low-risk HPV types. Statistical analyses will examine outcome variables including HPV prevalence, incidence, persistence and clearance. Logistic regression models will be used to estimate odds ratios and 95% confidence intervals for associations between the outcomes of interest and demographic/behavioural variables collected in the questionnaires. The longitudinal HPV infection data and detailed sexual history data collected in the questionnaires will allow us to develop individual-based network models of HPV transmission and will be used to parameterise multiscale models of HPV-related OPSC carcinogenesis. ETHICS AND DISSEMINATION: This study has been approved by the University of Michigan Institutional Review Board. All participants are consented in person by trained study staff. Study results will be disseminated through peer-reviewed publications. PMID- 30282680 TI - Risk of behaviour suggestive of opioid abuse: a protocol for a systematic review of validated assessment tools. AB - INTRODUCTION: Opioid use patterns of individuals with non-cancer pain are influenced by the behavioural dynamics of the individual in managing and properly following the prescription. The use of assessment tools for measuring the risk of behaviour suggestive of opioid abuse is important for health professionals who provide care to individuals with non-cancer pain. The aim of the proposed review is to analyse the psychometric properties of tools for measuring the risk of behaviour suggestive of opioid abuse in adults with non-cancer pain. METHODS AND ANALYSIS: The review process will be based on the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. The Consensus-Based Standards for the Selection of Health Measurement Instruments will be used to analyse the assessment tools. Two independent reviewers will perform the literature search and analysis procedures. Searches will be performed on PubMed, Web of Science, Cochrane, Scopus, and Cumulative Index to Nursing and Allied Health Literature databases, and the 'snowball' strategy will be employed. The inclusion criteria will be (1) validation studies, (2) assessment tools designed exclusively for measuring the risk of behaviour suggestive of opioid abuse and (3) assessment tools designed for evaluation of adults with chronic non-cancer pain. The titles and abstracts of the studies retrieved from the databases will be analysed for the preselection of articles, which will be submitted to a full-text analysis to define the final sample. Divergence of opinion between two reviewers will be resolved by consulting a third reviewer. ETHICS AND DISSEMINATION: The review will offer an overview of assessment tools available for measuring the risk of behaviour suggestive of opioid abuse, which is relevant to reducing the risk of deaths due to abusive consumption and for clinical management of adults with chronic non-cancer pain. PROSPERO REGISTRATION NUMBER: CRD42018081577. PMID- 30282681 TI - Association of Meniere's disease and retinal vascular calibre: a prospective observational study in China. AB - OBJECTIVE: It is believed that Meniere's disease (MD) is associated with vascular disorders, but few studies have reported the relationship between retinal vascular disorders and MD. We evaluated and compared the retinal vascular calibres in patients with MD with healthy subjects matched for age, sex and vascular risk factors using retinal photographs to explore the association between MD and retinal vascular calibre. STUDY DESIGN: A prospective study. SETTING: Tertiary referral centre. PARTICIPANTS: Sixty patients with MD and 62 healthy subjects matched for age, sex and vascular risk factors were enrolled in this study. Twenty-four patients with MD had migraines, and 36 patients with MD did not have migraines. MAIN OUTCOME MEASURE: Retinal vascular calibres were calculated and compared not only between patients with MD and healthy subjects but also between subgroups of patients with MD. RESULTS: Compared with healthy subjects, patients with MD had a slightly larger retinal artery calibre (126.30+/ 10.45vs 119.61+/-15.86, p=0.006) and a higher retinal artery/vein ratio (0.79+/ 0.09vs 0.75+/-0.10, p=0.005). Among patients with MD, those with migraines had a larger retinal artery calibre (130.73+/-11.55vs 123.35+/-8.61, p=0.006) than those without migraines. Moreover, the presence of migraines and the high frequency of vertigo attacks appeared to increase the retinal artery calibre. CONCLUSIONS: Our study suggests that a relationship exists between retinal vascular calibre and MD. Although the pathophysiological relationship between migraine and MD remains unclear, the presence of migraine attacks may aggravate endolymphatic hydrops (EH) and accelerate the outflow of EH in patients with MD. More extensive studies are required to explore the association between retinal vascular calibre and MD. PMID- 30282682 TI - Reduced prevalence of small-for-gestational-age and preterm birth for women of low socioeconomic position: a population-based cohort study comparing antenatal midwifery and physician models of care. AB - OBJECTIVE: Our aim was to investigate if antenatal midwifery care was associated with lower odds of small-for-gestational-age (SGA) birth, preterm birth (PTB) or low birth weight (LBW) compared with general practitioner (GP) or obstetrician (OB) models of care for women of low socioeconomic position. SETTING: This population-level, retrospective cohort study used province-wide maternity, medical billing and demographic data from British Columbia, Canada. PARTICIPANTS: Our study included 57 872 pregnant women, with low socioeconomic position, who: were residents of British Columbia, Canada, carried a singleton fetus, had low to moderate medical/obstetric risk, delivered between 2005 and 2012 and received medical insurance premium assistance. PRIMARY AND SECONDARY OUTCOME MEASURES: We report rates, adjusted ORs (aOR), and 95% CIs for the primary outcome, SGA birth (20 observations per athlete) and examined the relationship between athletic workloads and injuries. Since longitudinal research can be improved by aligning the (1) theoretical model, (2) temporal design and (3) statistical approach, we reviewed the statistical approaches used in these studies to evaluate how closely they aligned these three components. DESIGN: Methodological review. METHODS: After finding 6 systematic reviews and 1 consensus statement in our systematic search, we extracted 34 original prospective cohort studies of team sports that reported ILD (>20 observations per athlete) and examined the relationship between athletic workloads and injuries. Using Professor Linda Collins' three-part framework of aligning the theoretical model, temporal design and statistical approach, we qualitatively assessed how well the statistical approaches aligned with the intensive longitudinal nature of the data, and with the underlying theoretical model. Finally, we discussed the implications of each statistical approach and provide recommendations for future research. RESULTS: Statistical methods such as correlations, t-tests and simple linear/logistic regression were commonly used. However, these methods did not adequately address the (1) themes of theoretical models underlying workloads and injury, nor the (2) temporal design challenges (ILD). Although time-to-event analyses (eg, Cox proportional hazards and frailty models) and multilevel modelling are better-suited for ILD, these were used in fewer than a 10% of the studies (n=3). CONCLUSIONS: Rapidly accelerating availability of ILD is the norm in many fields of healthcare delivery and thus health research. These data present an opportunity to better address research questions, especially when appropriate statistical analyses are chosen. PMID- 30282684 TI - Cognitive control and daily affect regulation in major depression and borderline personality disorder: protocol for an experimental ambulatory assessment study in Berlin, Germany. AB - INTRODUCTION: Affective disturbances and difficulty in affect regulation are core features of major depressive disorder (MDD) as well as borderline personality disorder (BPD). Whereas depressed individuals are characterised by affective inertia, individuals with BPD are characterised by affective instability. Both groups have been found to use more maladaptive affect regulation strategies than healthy controls. Surprisingly, however, there have been hardly any studies directly comparing these two disorders to disentangle shared and disorder specific deficits in affective dynamics and affect regulation.Furthermore, theoretical models link deficits in affect regulation to deficits in cognitive control functions. Given that individuals with MDD or BPD are both characterised by impairments in cognitive control, the present study will further examine the link between individual differences in cognitive control and disturbances in affect dynamics and regulation in the daily life of individuals with MDD or BPD. METHODS AND ANALYSES: We will use a smartphone application to assess negative and positive affect as well as affect regulation strategies at eight times a day for 7 days. We will further employ four computerised tasks to assess two cognitive control functions, namely interference control and discarding irrelevant information from working memory. Our hypotheses will be tested using a multimethod approach. Power analyses determined a sample size of 159 (53 MDD, 53 BPD, 53 controls) to detect medium effect sizes. ETHICS AND DISSEMINATION: Ethics approval has been obtained from the Freie Universitat Berlin. Data collection started in January 2017 and will last until the end of 2018. Results will be disseminated to relevant psychotherapeutic and patient communities in peer reviewed journals, and at scientific conferences. PMID- 30282686 TI - Acupuncture treatment for knee osteoarthritis with sensitive points: protocol for a multicentre randomised controlled trial. AB - INTRODUCTION: There is a lack of curative medical treatment for patients with knee osteoarthritis (KOA). Acupuncture represents an important alternative therapy. According to the theory of traditional Chinese medicine and preliminary clinical evidence, the patients' acupoints and tender points may become sensitised when the body suffers from a disease state; stimulation of such sensitive points could lead to a disease improvement. It is thus hypothesised that acupuncture at highly sensitised points on patients with KOA would achieve better treatment outcomes than acupuncture at low/non-sensitised points. Previously, we conducted a pilot trial to prove the feasibility of further investigation. METHODS AND ANALYSIS: A three-arm, parallel, multicentre randomised controlled trial of 666 patients will be conducted at four hospitals of China. Eligible patients with KOA who consent to participate will be randomly assigned to a high-sensitisation group (patients receive acupuncture treatment at high-sensitive points), a low/non-sensitisation group (patients receive acupuncture treatment at low/non-sensitive points) or a waiting-list group (patients receive standard acupuncture treatment after the study is concluded) via a central randomisation system using 1:1:1 ratio. The primary outcome is the change of Western Ontario and McMaster Universities Osteoarthritis Index total score from baseline to 16 weeks. Outcome assessors and data analysts will be blinded and participants will be asked not to reveal their allocation to assessors. The outcome analyses will be performed both on the intention-to-treat and per-protocol population. The primary analyses will test if acupuncture at highly sensitised points would achieve statistically better treatment outcomes than acupuncture at low/non-sensitised points and no acupuncture (ie, waiting list), respectively. A small number of prespecified subgroup analyses will be conducted. ETHICS AND DISSEMINATION: Ethics approval has been granted by the Bioethics Subcommittee of West China Hospital, Sichuan University: 2017 (Number 228). Results will be expected to be published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03299439. PMID- 30282687 TI - Opportunistic HPV vaccination at age 16-23 and cervical screening attendance in Sweden: a national register-based cohort study. AB - OBJECTIVES: To investigate whether cervical screening attendance differs between human papillomavirus (HPV)-vaccinated and unvaccinated women and to investigate potential underlying socioeconomic factors. DESIGN: Prospective cohort using registry linkage of vaccinations, screening invitations, screening attendance and socioeconomic covariates. SETTING: Swedish national HPV vaccination and cervical screening programmes. PARTICIPANTS: All Swedish women born between 1988 and 1991 and invited to screening (n=261 434). OUTCOME MEASURES: All participants were followed for up to 3 years. Screening attendance was compared between HPV vaccinated and unvaccinated women. HR and 95% CI were estimated using Cox regression. RESULTS: Vaccination age averaged 18.1 years and the coverage for>=1 dose was 13.5%. In HPV-vaccinated women (n=35 460), screening attendance was higher than in unvaccinated women (n=225 974) (74%vs69%, p<0.001). The crude HR of attendance in HPV-vaccinated women was 1.32 (95% CI 1.30 to 1.34). A positive association remained after adjustment for education, income and migration history (HR=1.10, 95% CI 1.09 to 1.12). CONCLUSION: HPV-vaccinated women were more likely to attend screening than unvaccinated women. Yet, the question needs to be reassessed in routinely vaccinated cohorts, since the vaccinated women included here represent a selected group and may be prone to more health-conscious habits. PMID- 30282685 TI - Protocol for the Lactoferrin Infant Feeding Trial (LIFT): a randomised trial of adding lactoferrin to the feeds of very-low birthweight babies prior to hospital discharge. AB - INTRODUCTION: Very-low birthweight (VLBW, <1500 g) infants comprise about 1%-1.4% of all births in high-income countries. Every year, about 3000 VLBW babies in Australia and New Zealand receive intensive care. Many die or else survive with severe brain injury, retinopathy, late-onset sepsis or necrotising enterocolitis (NEC), each of which carries substantial risk of disability. METHODS AND ANALYSIS: This trial tests whether adding bovine lactoferrin (bLF) to feeds in VLBW infants improves (1) survival to hospital discharge free from brain injury, late-onset sepsis, NEC and treated retinopathy of prematurity (primary composite end point); (2) each component of the primary composite end point and (3) time to reach full enteral feeds, number of blood transfusions, chronic lung disease and length of hospital stay. It includes a cost-effectiveness analysis of bLF in improving survival free from major morbidity, and evaluates the effect of bLF on survival and developmental outcomes at 24 to 36 months corrected gestational age.This is a multicentre, two-arm, randomised trial comparing the treatment group receiving bLF added to breast milk or formula milk daily (up to 250 mg/kg/day bLF) versus the control group receiving no bLF supplementation. The intervention is administered until 34 completed weeks corrected gestation or for 2 weeks, whichever is longer, or until discharge home, if earlier. The target sample size of 1500 participants yields 85% power, at the two-sided 5% level significance, to detect a difference in proportions meeting the primary outcome assuming the true probability is 74% in controls and 80.5% in the bLF group. ETHICS AND DISSEMINATION: This protocol was approved by Northern Sydney Local Human Research Ethics Committee in January 2017 (Version 2.0, Reference 1003 118M) and other relevant ethics committees. The findings of the trial will be disseminated through peer-reviewed journals and conference presentations. TRIAL REGISTRATION NUMBER: ACTRN12611000247976; Pre-results. PMID- 30282688 TI - Randomised controlled trial of the Limit of Detection of Troponin and ECG Discharge (LoDED) strategy versus usual care in adult patients with chest pain attending the emergency department: study protocol. AB - INTRODUCTION: Observational data suggest a single high-sensitivity troponin blood test taken at emergency department (ED) presentation could be used to rule out major adverse cardiac events (MACE) in 10%-60% of ED patients with chest pain. This is done using an 'undetectable' cut-off (the Limit of Detection: LoD). We combined the LoD cut-off with ECG findings to create the LoDED strategy. We aim to establish whether the LoDED strategy works under real-life conditions, when compared with existing strategies, in a way that is cost-effective and acceptable to patients. METHODS AND ANALYSIS: This is a parallel-group pragmatic randomised controlled trial across UK EDs. Adults presenting to ED with suspected cardiac chest pain will be randomised 1:1. Existing rule-out strategies in current use across study centres, using serial high-sensitivity troponin testing, will be compared with the LoDED strategy. The primary outcome is successful early discharge (discharge from hospital within 4 hours of arrival) without MACE occurring within 30 days. Secondary outcomes include initial length of hospital stay; comparative costs; patient satisfaction and acceptability to patients. To detect a 9% difference between the early discharge rates (assuming an 8% rate in the standard care group) with 90% power, 594 patients need to be recruited, assuming a 95% follow-up rate. ETHICS AND DISSEMINATION: The study has been approved by the Frenchay Research Ethics Committee (reference 18/SW/0038). Results will be published in an international peer-reviewed journal. Lay summaries will be made available to patients. TRIAL REGISTRATION NUMBER: ISRCTN86184521; Pre-results. PMID- 30282689 TI - Effect of psychosocial work factors on the risk of certified absences from work for a diagnosed mental health problem: a protocol of a systematic review and meta analysis of prospective studies. AB - INTRODUCTION: Mental health problems (MHPs) are frequent and disabling and are the first or second leading cause of certified sickness absences from work in industrialised countries. They are generally long lasting and generate a considerable human and socioeconomic burden. The deleterious effect of adverse psychosocial work factors on MHP has been documented. However, the evidence regarding the effect of these factors on absences from work for an MHP has not been synthesised since 2007. The proposed systematic review aims to synthesise the effect of adverse psychosocial work factors from three validated theoretical models (the demand-control-support, effort-reward-imbalance and organisational justice models) on the risk of certified absences from work for diagnosed MHP among workers. METHOD AND ANALYSIS: A systematic search strategy will be conducted in seven databases: Medline, Embase, CINAHL, Web of Science, PsycInfo, Sociological abstracts and IBSS. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations, a multistep screening process by independent reviewers will lead to study selection. The search strategy was first run in 16 January 2017 and will be updated in October 2018. Only quantitative, prospective studies evaluating the effect of at least one psychosocial work factor from the validated theoretical models on certified absence from work for a diagnosed MHP will be considered for inclusion. Extracted data will be used for quantitative and qualitative evidence synthesis as well as to assess risk of bias and methodological quality. Meta-estimates will be provided for high-quality studies and by each psychosocial work factor, after considering homogeneity and number of studies. ETHICS AND DISSEMINATION: As this study will be based only on published studies, ethics approval is not required. Given that psychosocial works factors are frequent and modifiable, the results of this systematic review may provide evidence to support prevention strategies that can help to reduce the human social and economic burden associated with medically certified absences from work for an MHP.

PMID- 30282694 TI - An optical nanoreporter of endolysosomal lipid accumulation reveals enduring effects of diet on hepatic macrophages in vivo. AB - The abnormal accumulation of lipids within the endolysosomal lumen occurs in many conditions, including lysosomal storage disorders, atherosclerosis, nonalcoholic fatty liver disease (NAFLD), and drug-induced phospholipidosis. Current methods cannot monitor endolysosomal lipid content in vivo, hindering preclinical drug development and research into the mechanisms linking endolysosomal lipid accumulation to disease progression. We developed a single-walled carbon nanotube based optical reporter that noninvasively measures endolysosomal lipid accumulation via bandgap modulation of its intrinsic near-infrared emission. The reporter detected lipid accumulation in Niemann-Pick disease, atherosclerosis, and NAFLD models in vivo. By applying the reporter to the study of NAFLD, we found that elevated lipid quantities in hepatic macrophages caused by a high-fat diet persist long after reverting to a normal diet. The reporter dynamically monitored endolysosomal lipid accumulation in vivo over time scales ranging from minutes to weeks, indicating its potential to accelerate preclinical research and drug development processes. PMID- 30282693 TI - p95HER2-T cell bispecific antibody for breast cancer treatment. AB - T cell bispecific antibodies (TCBs) are engineered molecules that include, within a single entity, binding sites to the T cell receptor and to tumor-associated or tumor-specific antigens. The receptor tyrosine kinase HER2 is a tumor-associated antigen in ~25% of breast cancers. TCBs targeting HER2 may result in severe toxicities, likely due to the expression of HER2 in normal epithelia. About 40% of HER2-positive tumors express p95HER2, a carboxyl-terminal fragment of HER2. Using specific antibodies, here, we show that p95HER2 is not expressed in normal tissues. We describe the development of p95HER2-TCB and show that it has a potent antitumor effect on p95HER2-expressing breast primary cancers and brain lesions. In contrast with a TCB targeting HER2, p95HER2-TCB has no effect on nontransformed cells that do not overexpress HER2. These data pave the way for the safe treatment of a subgroup of HER2-positive tumors by targeting a tumor specific antigen. PMID- 30282695 TI - Huntingtin suppression restores cognitive function in a mouse model of Huntington's disease. AB - Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder caused by a mutation in the huntingtin (HTT) protein, resulting in acquisition of toxic functions. Previous studies have shown that lowering mutant HTT has the potential to be broadly beneficial. We previously identified HTT single nucleotide polymorphisms (SNPs) tightly linked to the HD mutation and developed antisense oligonucleotides (ASOs) targeting HD-SNPs that selectively suppress mutant HTT. We tested allele-specific ASOs in a mouse model of HD. Both early and late treatment reduced cognitive and behavioral impairments in mice. To determine the translational potential of the treatment, we examined the effect of ASO administration on HTT brain expression in nonhuman primates. The treatment induced robust HTT suppression throughout the cortex and limbic system, areas implicated in cognition and psychiatric function. The results suggest that ASOs specifically targeting mutated HTT might have therapeutic effects on HD-mediated cognitive impairments. PMID- 30282697 TI - Regulating 3D-printed medical products. AB - Additive manufacturing [also known as three-dimensional (3D) printing] is the layer-wise deposition of material to produce a 3D object.

Here, we describe the U.S. regulatory landscape of additive manufactured (3D-printed) medical devices and biologics and highlight key challenges and considerations. PMID- 30282696 TI - Anti-alpha4beta7 therapy targets lymphoid aggregates in the gastrointestinal tract of HIV-1-infected individuals. AB - Gut homing CD4+ T cells expressing the integrin alpha4beta7 are early viral targets and contribute to HIV-1 pathogenesis, likely by seeding the gastrointestinal (GI) tract with HIV. Although simianized anti-alpha4beta7 monoclonal antibodies have shown promise in preventing or attenuating the disease course of simian immunodeficiency virus in nonhuman primate studies, the mechanisms of drug action remain elusive. We present a cohort of individuals with mild inflammatory bowel disease and concomitant HIV-1 infection receiving anti alpha4beta7 treatment. By sampling the immune inductive and effector sites of the GI tract, we have discovered that anti-alpha4beta7 therapy led to a significant and unexpected attenuation of lymphoid aggregates, most notably in the terminal ileum. Given that lymphoid aggregates serve as important sanctuary sites for maintaining viral reservoirs, their attrition by anti-alpha4beta7 therapy has important implications for HIV-1 therapeutics and eradication efforts and defines a rational basis for the use of anti-alpha4beta7 therapy in HIV-1 infection. PMID- 30282698 TI - GABAA receptor availability is not altered in adults with autism spectrum disorder or in mouse models. AB - Preliminary studies have suggested that gamma-aminobutyric acid type A (GABAA) receptors, and potentially the GABAA alpha5 subtype, are deficient in autism spectrum disorder (ASD). However, prior studies have been confounded by the effects of medications, and these studies did not compare findings across different species. We measured both total GABAA and GABAA alpha5 receptor availability in two positron emission tomography imaging studies. We used the tracer [11C]flumazenil in 15 adults with ASD and in 15 control individuals without ASD and the tracer [11C]Ro15-4513 in 12 adults with ASD and in 16 control individuals without ASD. All participants were free of medications. We also performed autoradiography, using the same tracers, in three mouse models of ASD: the Cntnap2 knockout mouse, the Shank3 knockout mouse, and mice carrying a 16p11.2 deletion. We found no differences in GABAA receptor or GABAA alpha5 subunit availability in any brain region of adults with ASD compared to those without ASD. There were no differences in GABAA receptor or GABAA alpha5 subunit availability in any of the three mouse models. However, adults with ASD did display altered performance on a GABA-sensitive perceptual task. Our data suggest that GABAA receptor availability may be normal in adults with ASD, although GABA signaling may be functionally impaired.

PMID- 30282700 TI - Advances in the Treatment of Hemophilia: Implications for Laboratory Testing. AB - BACKGROUND: Until recently, clinical laboratories have monitored hemophilia treatment by measuring coagulation factors before/after infusion of human-derived or recombinant factors. Substantial changes are expected in the near future based on new therapeutic approaches that have been or are being developed. CONTENT: Hemophilia treatment includes replacement therapy with human-derived/recombinant factors or treatment with bypassing agents for patients without or with inhibitors, respectively. Accordingly, laboratory methods for monitoring include one-stage clotting or chromogenic assays meant to measure either factor VIII/IX or global coagulation tests to measure the effect of bypassing agents. Recently, modified long-acting coagulation factors have been introduced for which discrepant results may be expected when measurement is performed with one-stage clotting or chromogenic assays. Currently, novel drugs not based on coagulation factors are under development and are being tested in clinical studies. These drugs do require new methods and therefore laboratory evaluation of hemophilia will undergo dramatic changes in the near future. SUMMARY: From the analysis of the current practice and literature, we draw the following conclusions: (a) Thrombin generation or thromboelastometry are the logical candidate assays to monitor bypassing agents. (b) Considerable differences are expected when measuring modified long-acting coagulation factors, depending on whether one stage or chromogenic assays are used. Although no definitive conclusions can presently be drawn, chromogenic assays are probably more suitable than one-stage clotting. (c) Novel drugs not based on coagulation factors such as emicizumab, fitusiran, or concizumab that are entering the market do require alternative methods that are not yet well established. PMID- 30282699 TI - Impact of Gastric Banding Versus Metformin on beta-Cell Function in Adults With Impaired Glucose Tolerance or Mild Type 2 Diabetes. AB - OBJECTIVE: Type 2 diabetes (T2D) results from progressive loss of beta-cell function. The BetaFat study compared gastric banding and metformin for their impact on beta-cell function in adults with moderate obesity and impaired glucose tolerance (IGT) or recently diagnosed, mild T2D. RESEARCH DESIGN AND METHODS: Eighty-eight people aged 21-65 years, BMI 30-40 kg/m2, with IGT or diabetes known for <1 year, were randomized to gastric banding or metformin for 2 years. Hyperglycemic clamps (11.1 mmol/L) followed by arginine injection at maximally potentiating glycemia (>25 mmol/L) were performed at baseline, 12 months, and 24 months to measure steady-state C-peptide (SSCP) and acute C-peptide response to arginine at maximum glycemic potentiation (ACPRmax) and insulin sensitivity (M/I). RESULTS: At 24 months, the band group lost 10.7 kg; the metformin group lost 1.7 kg (P < 0.01). Insulin sensitivity increased 45% in the band group and 25% in the metformin group (P = 0.30 between groups). SSCP adjusted for insulin sensitivity fell slightly but not significantly in each group (P = 0.34 between groups). ACPRmax adjusted for insulin sensitivity fell significantly in the metformin group (P = 0.002) but not in the band group (P = 0.25 between groups). HbA1c fell at 12 and 24 months in the band group (P < 0.004) but only at 12 months (P < 0.01) in the metformin group (P > 0.14 between groups). Normoglycemia was present in 22% and 15% of band and metformin groups, respectively, at 24 months (P = 0.66 between groups). CONCLUSIONS: Gastric banding and metformin had similar effects to preserve beta-cell function and stabilize or improve glycemia over a 2-year period in moderately obese adults with IGT or recently diagnosed, mild T2D.

PMID- 30282703 TI - Collaboration between academics and industry in clinical trials: cross sectional study of publications and survey of lead academic authors. AB - OBJECTIVES: To determine the role of academic authors, funders, and contract research organisations in industry funded trials of vaccines, drugs, and devices and to determine lead academic authors' experiences with industry funder collaborations. DESIGN: Cross sectional analysis of trial publications and survey of lead academic authors. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: The most recent 200 phase III and IV trials of vaccines, drugs, and devices with full industry funding, at least one academic author, published in one of the top seven high impact general medical journals (New England Journal of Medicine, Lancet, JAMA, BMJ, Annals of Internal Medicine, JAMA Internal Medicine, and PLoS Medicine). RESULTS: Employees of industry funders co-authored 173 (87%) of publications; 183 (92%) trials reported involvement of funders in design, and 167 (84%) reported involvement of academic authors. Data analysis involved the funder in 146 (73%) trials and the academic authors in 79 (40%). Trial reporting involved the funder in 173 (87%) trials and academic authors in 197 (99%). Contract research organisations were involved in the reporting of 123 (62%) trials.Eighty (40%) of 200 lead academic authors responded to the survey. Twenty nine (33%) of the 80 responders reported that academics had final say on the design. Ten responders described involvement of an unnamed funder and/or contract research organisation employee in the data analysis and/or reporting. Most academic authors found the collaboration with industry funder beneficial, but 3 (4%) experienced delay in publication due to the industry funder and 9 (11%) reported disagreements with the industry funder, mostly concerning trial design and reporting. CONCLUSIONS: Industry employees and academic authors are involved in the design, conduct, and reporting of most industry funded trials in high impact journals. However, data analysis is often conducted without academic involvement. Academics view the collaboration as beneficial, but some report loss of academic freedom. PMID- 30282704 TI - Dynamin Is Required for Efficient Cytomegalovirus Maturation and Envelopment. AB - Cytomegalovirus secondary envelopment occurs in a virus-induced cytoplasmic assembly compartment (vAC) generated via a drastic reorganization of the membranes of the secretory and endocytic systems. Dynamin is a eukaryotic GTPase that is implicated in membrane remodeling and endocytic membrane fission events; however, the role of dynamin in cellular trafficking of viruses beyond virus entry is only partially understood. Mouse embryonic fibroblasts (MEF) engineered to excise all three isoforms of dynamin were infected with mouse cytomegalovirus (MCMV-K181). Immediate-early (IE1; m123) viral protein was detected in these triple dynamin knockout (TKO) cells, as well as in mock-induced parental MEF, at early times postinfection, although levels were reduced in TKO cells, indicating that virus entry was affected but not eliminated. Levels of IE1 protein and another viral early protein (m04) were normalized by 48 h postinfection; however, late protein (m55; gB) expression was reduced in infected TKO cells compared to parental MEF. Ultrastructural analysis revealed intact stages of nuclear virus maturation in both cases with equivalent numbers of nucleocapsids containing packaged viral DNA (C-capsids), indicating successful viral DNA replication, capsid assembly, and genome packaging. Most importantly, severe defects in virus envelopment were visualized in TKO cells but not in parental cells. Dynamin inhibitor (dynasore)-treated MEF showed a phenotype similar to TKO cells upon mouse cytomegalovirus infection, confirming the role of dynamin in late maturation processes. In summary, dynamin-mediated endocytic pathways are critical for the completion of cytoplasmic stages of cytomegalovirus maturation.IMPORTANCE Viruses are known to exploit specific cellular functions at different stages of their life cycle in order to replicate, avoid immune recognition by the host and to establish a successful infection. Cytomegalovirus (CMV)-infected cells are characterized by a prominent cytoplasmic inclusion (virus assembly compartment [vAC]) that is the site of virus maturation and envelopment. While endocytic membranes are known to be the functional components of vAC, knowledge of specific endocytic pathways implicated in CMV maturation and envelopment is lacking. We show here that dynamin, which is an integral part of host endocytic machinery, is largely dispensable for early stages of CMV infection but is required at a late stage of CMV maturation. Studies on dynamin function in CMV infection will help us understand the host-virus interaction pathways amenable to targeting by conventional small molecules, as well as by newer generation nucleotide-based therapeutics (e.g., small interfering RNA, CRISPR/CAS gRNA, etc.). PMID- 30282705 TI - Mapping the nonstructural protein interaction network of porcine reproductive and respiratory syndrome virus. AB - Porcine reproductive and respiratory syndrome virus (PRRSV) is a positive stranded RNA virus belonging to the family Arteriviridae Synthesis of the viral RNA is directed by replication/transcription complexes (RTC) that are composed of mainly a network of PRRSV nonstructural proteins (nsps) and likely cellular proteins. Here we mapped the interaction network among PRRSV nsps by using yeast two hybrid screening in conjunction with co-immunoprecipitation (Co-IP) and co transfection assays. We identified a total of 24 novel interactions and found that the interactions were centered on ORF1b-encoded nsps that were mainly connected by the transmembrane proteins nsp2, nsp3 and nsp5. Interestingly, the interactions of the core enzymes nsp9 and nsp10 with transmembrane proteins did not occur in a straightforward manner, as they worked in the Co-IP assay but were poorly capable of finding each other within intact mammalian cells. Further proof that they can interact within cells required the engineering of N-terminal truncations of both nsp9 and nsp10. However, despite the poor co-localization relationship in co-transfected cells, both nsp9 and nsp10 came together with membrane proteins (e.g., nsp2) at the viral RTC in PRRSV-infected cells. Thus, our results indicate the existence of a complex interaction network among PRRSV nsps and raise the possibility that the recruitment of key replicase proteins to membrane-associated nsps may involve some regulatory mechanisms during infection.ImportanceSynthesis of PRRSV RNAs within host cells depends on the efficient and correct assembly of replication and transcription complexes (RTC) that takes places on modified intracellular membranes. As an important step toward dissecting this poorly understood event, we investigated the interaction network among PRRSV nsps. Our studies established a comprehensive interaction map for PRRSV nsps and revealed important players within the network. The results also highlight the likely existence of a regulated recruitment of PRRSV core enzymes nsp9 and nsp10 to viral membrane nsps during PRRSV RTC assembly. PMID- 30282706 TI - Nonpathogenic Heterologous Prions Can Interfere with Prion Infection in a Strain Dependent Manner. AB - Co-occurrence of different prion strains into the same host has been recognized as a natural phenomenon for several sporadic Creutzfeldt-Jakob disease (sCJD) patients and natural scrapie cases. The final outcome of prion coinfection is not easily predictable. In addition to the usual factors that influence prion conversion, the replication of one strain may entail positive or negative consequences to the other. The main aim of this study was to gain insights into the prion coinfection and interference concepts and their potential therapeutic implications. Here, different mouse models were challenged with several combinations of prion strains coupled on the basis of the lengths of their incubation periods and the existence/absence of a species barrier in the tested animal model. We found that nontransmissible strains can interfere the replication of fully transmissible strains when there is a species transmission barrier involved, as happened with the combination of a mouse (22L) and a human (sCJD) strain. However, this phenomenon seems to be strain dependent, since no interference was observed when the human strain coinoculated was vCJD. For the other combinations tested in this study, the results suggest that both strains replicate independently without effect on the replication of one over the other. It is common that the strain with more favorable conditions (e.g., a higher speed of disease development or the absence of a species barrier) ends being the only one detectable at the terminal stage of the disease. However, this does not exclude the replication of the least favored strain, leading to situations of the coexistence of prion strains.IMPORTANCE As a general conclusion, the outcome of prion coinfection is strongly dependent on the strain combination and the model utilized and is therefore difficult to predict. The coexistence of several prion strains may remain undetected if one of the strains has more favorable conditions to replicate in the host. The use of several models (such as a transgenic mouse expressing PrP from different species) to analyze field prion isolates is recommended to avoid this situation. The inference effect exerted by nonreplicative prion strains should be considered an interesting tool to advance in new therapeutic strategies for treating prion diseases; it may even be a proper therapeutic strategy. PMID- 30282707 TI - Herpes Simplex Virus 1 Latency and the Kinetics of Reactivation Are Regulated by a Complex Network of Interactions between the Herpesvirus Entry Mediator, Its Ligands (gD, BTLA, LIGHT, and CD160), and the Latency-Associated Transcript. AB - Recently, we reported that the herpesvirus entry mediator (HVEM; also called TNFRSF14 or CD270) is upregulated by the latency-associated transcript (LAT) of herpes simplex virus 1 (HSV-1) and that the absence of HVEM affects latency reactivation but not primary infection in ocularly infected mice. gD has been shown to bind to HVEM. LIGHT (TNFSF14), CD160, and BTLA (B- and T-lymphocyte attenuator) also interact with HVEM and can interfere with HSV gD binding. It was not known if LIGHT, CD160, or BTLA affected the level of latency reactivation in the trigeminal ganglia (TG) of latently infected mice. To address this issue, we ocularly infected LIGHT-/-, CD160-/-, and BTLA-/- mice with LAT(+) and LAT(-) viruses, using similarly infected wild-type (WT) and HVEM-/- mice as controls. The amount of latency, as determined by the levels of gB DNA in the TG of the LIGHT-/-, CD160-/-, and BTLA-/- mice infected with either LAT(+) or LAT(-) viruses, was lower than that in WT mice infected with LAT(+) virus and was similar in WT mice infected with LAT(-) virus. The levels of LAT RNA in HVEM-/-, LIGHT-/-, CD160-/-, and BTLA-/- mice infected with LAT(+) virus were similar and were lower than the levels of LAT RNA in WT mice. However, LIGHT-/-, CD160-/-, and BTLA-/- mice, independent of the presence of LAT, had levels of reactivation similar to those of WT mice infected with LAT(+) virus. Faster reactivation correlated with the upregulation of HVEM transcript. The LIGHT-/-, CD160-/-, and BTLA-/- mice had higher levels of HVEM expression, and this, along with the absence of BTLA, LIGHT, or CD160, may contribute to faster reactivation, while the absence of each molecule, independent of LAT, may have contributed to lower latency. This study suggests that, in the absence of competition with gD for binding to HVEM, LAT RNA is important for WT levels of latency but not for WT levels of reactivation.IMPORTANCE The effects of BTLA, LIGHT, and CD160 on latency reactivation are not known. We show here that in BTLA, LIGHT, or CD160 null mice, latency is reduced; however, HVEM expression is upregulated compared to that of WT mice, and this upregulation is associated with higher reactivation that is independent of LAT but dependent on gD expression. Thus, one of the mechanisms by which BTLA, LIGHT, and CD160 null mice enhance reactivation appears to be the increased expression of HVEM in the presence of gD. Thus, our results suggest that blockade of HVEM-LIGHT-BTLA-CD160 contributes to reduced HSV-1 latency and reactivation. PMID- 30282708 TI - Remodeling mTORC1 Responsiveness to Amino Acids by the Herpes Simplex Virus UL46 and Us3 Gene Products Supports Replication during Nutrient Insufficiency. AB - By sensing fundamental parameters, including nutrient availability, activated mechanistic target of rapamycin complex 1 (mTORC1) suppresses catabolic outcomes and promotes anabolic processes needed for herpes simplex virus 1 (HSV-1) productive growth. While the virus-encoded Us3 Ser/Thr kinase is required to activate mTORC1, whether stress associated with amino acid insufficiency impacts mTORC1 activation in infected cells and virus reproduction was unknown. In contrast to uninfected cells, where amino acid withdrawal inhibits mTORC1 activation, we demonstrate that mTORC1 activity is sustained in HSV-1-infected cells during amino acid insufficiency. We show that in the absence of Us3, the insensitivity of mTORC1 to amino acid withdrawal in infected cells was dependent on the host kinase Akt and establish a role for the HSV-1 UL46 gene product, which stimulates phosphatidylinositol (PI) 3-kinase signaling. Significantly, virus reproduction during amino acid insufficiency was stimulated by the viral UL46 gene product. By synergizing with Us3, UL46 reprograms mTORC1 such that it is insensitive to amino acid withdrawal and supports sustained mTORC1 activation and virus reproduction during amino acid insufficiency. This identifies an unexpected function for UL46 in supporting virus reproduction during physiological stress and identifies a new class of virus-encoded mTORC1 regulators that selectively uncouple mTORC1 activation from amino acid sufficiency.IMPORTANCE Mechanistic target of rapamycin complex 1 (mTORC1) is a multisubunit cellular kinase that coordinates protein synthesis with changing amino acid levels. During amino acid insufficiency, mTORC1 is repressed in uninfected cells, dampening protein synthesis and potentially restricting virus reproduction. Here, we establish that HSV-1 alters the responsiveness of mTORC1 to metabolic stress resulting from amino acid insufficiency. Unlike in uninfected cells, mTORC1 remains activated in HSV-1-infected cells deprived of amino acids. Synergistic action of the HSV-1 UL46 gene product, which stimulates PI 3-kinase, and the Us3 kinase supports virus reproduction during amino acid withdrawal. These results define how HSV-1, a medically important human pathogen associated with a range of diseases, uncouples mTORC1 activation from amino acid availability. Furthermore, they help explain how the virus reproduces during physiological stress. Reproduction triggered by physiological stress is characteristic of herpesvirus infections, where lifelong latency is punctuated by episodic reactivation events.

AB - Extracellular HBV RNA has been detected in both HBV-replicating cell culture media and sera from chronic hepatitis B (CHB) patients, but its exact origin and composition remain controversial. Here, we demonstrated that extracellular HBV RNA species were of heterogeneous lengths, ranging from the length of pregenomic RNA to a few hundred nucleotides. In cell models, these RNAs were predominantly associated with naked capsids, although virions also harbored a minority of them. Moreover, HBV RNAs in hepatitis B patients' blood circulation were localized in unenveloped capsids in the form of capsid-antibody complexes (CACs) and in virions. Furthermore, we showed that extracellular HBV RNAs could serve as the template for viral DNA synthesis. In conclusion, extracellular HBV RNAs mainly consist of pgRNA or the pgRNA species degraded by the RNase H domain of the polymerase in the process of viral DNA synthesis and circulate as CACs and virions. Their presence in blood circulation of CHB patients may be exploited to develop novel biomarkers for HBV persistence.IMPORTANCE Although increasing evidence suggests the presence of extracellular HBV RNA species, their origin and molecular forms are still under debate. In addition to the infectious virions, HBV is known to secrete several species of incomplete viral particles, including hepatitis B surface antigen (HBsAg) particles, naked capsids, and empty virions, during its replication cycle. Here, we demonstrated that extracellular HBV RNAs were associated with naked capsids and virions in HepAD38 cells. Interestingly, we found that unenveloped capsids circulate in the blood of hepatitis B patients in the form of CACs and, together with virions, serve as vehicles carrying these RNA molecules. Moreover, extracellular HBV RNAs are heterogeneous in length and represent either pregenomic RNA (pgRNA) or products of incomplete reverse transcription during viral replication. These findings provide a conceptual basis for further application of extracellular RNA species as novel biomarkers for HBV persistence. PMID- 30282710 TI - Engineered small molecule control of influenza A virus replication. AB - Influenza A virus (IAV) remains a global health concern despite the availability of a seasonal vaccine. It is difficult to predict which strains will circulate during influenza season, and therefore extremely challenging to test novel vaccines in the human population. To overcome this obstacle, new vaccines must be tested in challenge studies. This approach poses significant safety problems, as current pharmacological interventions for IAV are poorly efficacious. New methods are needed to enhance the safety of these challenge studies. Here, we generate a virus expressing a small molecule-assisted shutoff (SMASh) tag as a safety switch for IAV replication. Addition of the SMASh tag to an essential IAV protein allows for small molecule-mediated inhibition of replication. Treatment with this drug controls SMASh-tagged virus replication in vitro and in vivo This model for restriction of viral replication has potential for broad applications in vaccine studies, virotherapy, and basic virus research.Importance Influenza A virus (IAV) causes significant morbidity and mortality worldwide annually, despite the availability of new formulations of the vaccine each season. There is a critical need to develop more efficacious vaccines. However, testing novel vaccines in the human population in controlled studies is difficult due to the limited availability and efficacy of intervention strategies should the vaccine fail. There are also significant safety concerns for work with highly pathogenic IAV strains in the laboratory. Therefore, novel strategies are needed to improve the safety of vaccine studies and highly pathogenic IAV research. Here we developed an IAV strain engineered to contain a small molecule-mediated safety switch. This tag, when attached to an essential viral protein, allows for regulation of IAV replication in vitro and in vivo This strategy provides a platform for regulation of virus replication without targeting viral proteins directly. PMID- 30282711 TI - Exosomes exploit the virus entry machinery and pathway to transmit IFN-alpha induced antiviral activity. AB - Interferon-alpha (IFN-alpha) induces the transfer of resistance to hepatitis B virus (HBV) from liver nonparenchymal cells (LNPCs) to hepatocytes via exosomes. However, little is known about the entry machinery and pathway involved in the transmission of IFN-alpha-induced antiviral activity. Here, we found that macrophage exosomes uniquely depend on T cell immunoglobulin and mucin receptor 1 (TIM-1), a hepatitis A virus (HAV) receptor, to enter hepatocytes for delivering IFN-alpha-induced anti-HBV activity. Moreover, two primary endocytic routes for virus infection, clathrin-mediated endocytosis (CME) and macropinocytosis, collaborate to permit exosome entry and anti-HBV activity transfer. Subsequently, lysobisphosphatidic acid (LBPA), an anionic lipid closely related to endosome penetration of virus, facilitates membrane fusion of exosomes in late endosomes/multivesicular bodies (LEs/MVBs) and the accompanying exosomal cargo uncoating. Together, this study provides comprehensive insights into the transmission route of macrophage exosomes to efficiently deliver IFN-alpha induced antiviral substances and highlights the similarities between the entry mechanisms of exosomes and virus.Importance Our previous study showed that LNPC derived exosomes could transmit IFN-alpha-induced antiviral activity to HBV replicating hepatocytes, but the concrete transmission mechanisms which include exosome entry and exosomal cargo release remain unclear. In this study, we found that virus entry machinery and pathway were also applied to exosome-mediated cell to-cell antiviral activity transfer. Macrophage-derived exosomes distinctively exploit hepatitis A virus receptor for access to hepatocytes. Later, CME and macropinocytosis are utilized by exosomes which is followed by exosome-endosome fusion for efficient transfer of IFN-alpha-induced anti-HBV activity. We believe that understanding the cellular entry pathway of exosomes will be beneficial to designing exosomes as efficient vehicles for antiviral therapy. PMID- 30282712 TI - Phosphatidylinositol 3-Kinase/Akt and MEK/ERK Signaling Pathways Facilitate Sapovirus Trafficking and Late Endosomal Acidification for Viral Uncoating in LLC PK Cells. AB - Sapovirus, an important cause of acute gastroenteritis in humans and animals, travels from the early to the late endosomes and requires late endosomal acidification for viral uncoating. However, the signaling pathways responsible for these viral entry processes remain unknown. Here we demonstrate the receptor mediated early activation of phosphatidylinositol 3-kinase (PI3K)/Akt and mitogen activated protein extracellular signal-regulated kinase/extracellular signal regulated kinase (MEK/ERK) signaling pathways involved in sapovirus entry processes. Both signaling pathways were activated during the early stage of porcine sapovirus (PSaV) infection. However, depletion of the cell surface carbohydrate receptors by pretreatment with sodium periodate or neuraminidase reduced the PSaV-induced early activation of these signaling pathways, indicating that PSaV binding to the cell surface carbohydrate receptors triggered these cascades. Addition of bile acid, known to be essential for PSaV escape from late endosomes, was also found to exert a stiffening effect to stimulate both pathways. Inhibition of these signaling pathways by use of inhibitors specific for PI3K or MEK or small interfering RNAs (siRNAs) against PI3K or MEK resulted in entrapment of PSaV particles in early endosomes and prevented their trafficking to late endosomes. Moreover, phosphorylated PI3K and ERK coimmunoprecipitated subunit E of the V-ATPase proton pump that is important for endosomal acidification. Based on our data, we conclude that receptor binding of PSaV activates both PI3K/Akt and MEK/ERK signaling pathways, which in turn promote PSaV trafficking from early to late endosomes and acidification of late endosomes for PSaV uncoating. These signaling cascades may provide a target for potent therapeutics against infections by PSaV and other caliciviruses.IMPORTANCE Sapoviruses cause acute gastroenteritis in both humans and animals. However, the host signaling pathway(s) that facilitates host cell entry by sapoviruses remains largely unknown. Here we demonstrate that porcine sapovirus (PSaV) activates both PI3K/Akt and MEK/ERK cascades at an early stage of infection. Removal of cell surface receptors decreased PSaV-induced early activation of both cascades. Moreover, blocking of PI3K/Akt and MEK/ERK cascades entrapped PSaV particles in early endosomes and prevented their trafficking to the late endosomes. PSaV induced early activation of PI3K and ERK molecules further mediated V-ATPase dependent late endosomal acidification for PSaV uncoating. This work unravels a new mechanism by which receptor-mediated early activation of both cascades may facilitate PSaV trafficking from early to late endosomes and late endosomal acidification for PSaV uncoating, which in turn can be a new target for treatment of sapovirus infection. PMID- 30282713 TI - Salinomycin Inhibits Influenza Virus Infection by Disrupting Endosomal Acidification and Viral Matrix Protein 2 Function. AB - Screening of chemical libraries with 2,000 synthetic compounds identified salinomycin as a hit against influenza A and B viruses, with 50% effective concentrations ranging from 0.4 to 4.3 MUM in cells. This compound is a carboxylic polyether ionophore that exchanges monovalent ions for protons across lipid bilayer membranes. Monitoring the time course of viral infection showed that salinomycin blocked nuclear migration of viral nuclear protein (NP), the most abundant component of the viral ribonucleoprotein (vRNP) complex. It caused cytoplasmic accumulation of NP, particularly within perinuclear endosomes, during virus entry. This was primarily associated with failure to acidify the endosomal lysosomal compartments. Similar to the case with amantadine (AMT), proton channel activity of viral matrix protein 2 (M2) was blocked by salinomycin. Using purified retroviral Gag-based virus-like particles (VLPs) with M2, it was proved that salinomycin directly affects the kinetics of a proton influx into the particles but in a manner different from that of AMT. Notably, oral administration of salinomycin together with the neuraminidase inhibitor oseltamivir phosphate (OSV-P) led to enhanced antiviral effect over that with either compound used alone in influenza A virus-infected mouse models. These results provide a new paradigm for developing antivirals and their combination therapy that control both host and viral factors.IMPORTANCE Influenza virus is a main cause of viral respiratory infection in humans as well as animals, occasionally with high mortality. Circulation of influenza viruses resistant to the matrix protein 2 (M2) inhibitor, amantadine, is highly prevalent. Moreover, the frequency of detection of viruses resistant to the neuraminidase inhibitors, including oseltamivir phosphate (OSV-P) or zanamivir, is also increasing. These issues highlight the need for discovery of new antiviral agents with different mechanisms. Salinomycin as the monovalent cation-proton antiporter exhibited consistent inhibitory effects against influenza A and B viruses. It plays multifunctional roles by blocking endosomal acidification and by inactivating the proton transport function of M2, the key steps for influenza virus uncoating. Notably, salinomycin resulted in marked therapeutic effects in influenza virus infected mice when combined with OSV-P, suggesting that its chemical derivatives could be developed as an adjuvant antiviral therapy to treat influenza infections resistant or less sensitive to existing drugs. PMID- 30282714 TI - Amino acid residue 217 in the hemagglutinin glycoprotein is a key mediator of avian influenza H7N9 virus antigenicity. AB - Avian influenza viruses continue to evolve and acquire mutations that facilitate antigenic drift and virulence change. In 2017, low pathogenicity H7N9 avian influenza viruses evolved to a high pathogenicity phenotype in China. The comparative antigenic analysis between the low and high pathogenicity virus strains showed marked variability. In order to identify residues that may be linked to the antigenic change amongst the H7N9 viruses, we serially passaged the viruses in the presence of homologous ferret antisera. Progeny viruses able to overcome the neutralising capacity of the antisera were sequenced. The analysis showed that the emergent immune escaped viruses contained mutations A125T, A151T and L217Q in the hemagglutinin (HA) glycoprotein as early as passage 5 and these mutations persisted until passage 10. The results revealed that a single mutation L217Q in the HA of H7N9 virus led to 23- and 8-fold reductions in hemagglutination inhibition (HI) titre with ferret and chicken antisera, respectively. Further analysis showed that this change also contributed to antigenic differences between the low and high pathogenicity H7N9 viruses, therein, playing a major role in their antigenic diversification. Therefore, evolutionary changes at amino acid position 217 in the H7N9 viruses can serve as a genetic marker for virus antigenic diversity during vaccine seed matching and selection. The in vitro immune escape mutant selection method used in this study could also aid in the prediction of emerging antigenic variants in the naturally infected or immunised animals.IMPORTANCE Avian influenza H7N9 viruses circulating in poultry and wild birds continue to evolve and acquire important phenotypic changes. Mutations to the virus hemagglutinin (HA) glycoprotein can modulate virus antigenicity and facilitate virus escape from natural or vaccine-induced immunity. The focus of this study was to identify evolutionary markers in the HA of H7N9 that drive escape from antibody-based immunity. To achieve this, we propagated low pathogenicity H7N9 virus in the presence of polyclonal antisera derived from ferrets infected with the same strain of virus (homologous antisera). This selection process was repeated 10 times. The HA gene sequence of viruses recovered after the 5th passage showed that the viruses readily acquired mutation at three different amino acid positions (A125T, A151T and L217Q). Further functional analysis of these mutations confirmed that mutation at residue HA 217 was responsible for mediating changes to the immunological properties of the H7N9 virus. PMID- 30282715 TI - Using Antibodies and Mutants To Localize the Presumptive gH/gL Binding Site on Herpes Simplex Virus gD. AB - HSV virus-cell and cell-cell fusion requires multiple interactions between four essential virion envelope glycoproteins, gD, gB, gH, and gL, and between gD and a cellular receptor, nectin-1 or herpesvirus entry mediator (HVEM). Current models suggest that binding of gD to receptors induces a conformational change that leads to activation of gH/gL and consequent triggering of the prefusion form of gB to promote membrane fusion. Since protein-protein interactions guide each step of fusion, identifying the sites of interaction may lead to the identification of potential therapeutic targets that block this process. We have previously identified two "faces" on gD: one for receptor binding and the other for its presumed interaction with gH/gL. We previously separated the gD monoclonal antibodies (MAbs) into five competition communities. MAbs from two communities (MC2 and MC5) neutralize virus infection and block cell-cell fusion but do not block receptor binding, suggesting that they block binding of gD to gH/gL. Using a combination of classical epitope mapping of gD mutants with fusion and entry assays, we identified two residues (R67 and P54) on the presumed gH/gL interaction face of gD that allowed for fusion and viral entry but were no longer sensitive to inhibition by MC2 or MC5, yet both were blocked by other MAbs. As neutralizing antibodies interfere with essential steps in the fusion pathway, our studies strongly suggest that these key residues block the interaction of gD with gH/gL.IMPORTANCE Virus entry and cell-cell fusion mediated by HSV require gD, gH/gL, gB, and a gD receptor. Neutralizing antibodies directed against any of these proteins bind to residues within key functional sites and interfere with an essential step in the fusion pathway. Thus, the epitopes of these MAbs identify critical, functional sites on their target proteins. Unlike many anti-gD MAbs, which block binding of gD to a cellular receptor, two, MC2 and MC5, block a separate, downstream step in the fusion pathway which is presumed to be the activation of the modulator of fusion, gH/gL. By combining epitope mapping of a panel of gD mutants with fusion and virus entry assays, we have identified residues that are critical in the binding and function of these two MAbs. This new information helps to define the site of the presumptive interaction of gD with gH/gL, of which we have limited knowledge. PMID- 30282716 TI - Targeting of the Nasal Mucosa by Japanese Encephalitis Virus for Non-Vector-Borne Transmission. AB - The mosquito-borne Japanese encephalitis virus (JEV) causes severe central nervous system diseases and cycles between Culex mosquitoes and different vertebrates. For JEV and some other flaviviruses, oronasal transmission is described, but the mode of infection is unknown. Using nasal mucosal tissue explants and primary porcine nasal epithelial cells (NEC) at the air-liquid interface (ALI) and macrophages as ex vivo and in vitro models, we determined that the nasal epithelium could represent the route of entry and exit for JEV in pigs. Porcine NEC at the ALI exposed to with JEV resulted in apical and basolateral virus shedding and release of monocyte recruiting chemokines, indicating infection and replication in macrophages. Moreover, macrophages stimulated by alarmins, including interleukin-25, interleukin-33, and thymic stromal lymphopoietin, were more permissive to the JEV infection. Altogether, our data are important to understand the mechanism of non-vector-borne direct transmission of Japanese encephalitis virus in pigs.IMPORTANCE JEV, a main cause of severe viral encephalitis in humans, has a complex ecology composed of a mosquito-waterbird cycle and a cycle involving pigs, which amplifies virus transmission to mosquitoes, leading to increased human cases. JEV can be transmitted between pigs by contact in the absence of arthropod vectors. Moreover, virus or viral RNA is found in oronasal secretions and the nasal epithelium. Using nasal mucosa tissue explants and three-dimensional porcine nasal epithelial cells cultures and macrophages as ex vivo and in vitro models, we determined that the nasal epithelium could be a route of entry as well as exit for the virus. Infection of nasal epithelial cells resulted in apical and basolateral virus shedding and release of monocyte recruiting chemokines and therefore infection and replication in macrophages, which is favored by epithelial-cell-derived cytokines. The results are relevant to understand the mechanism of non-vector-borne direct transmission of JEV. PMID- 30282717 TI - The Nonstructural Protein 11-kDa of Human Parvovirus B19 Facilitates Viral DNA Replication by Interacting with Grb2 through Its Proline-rich Motifs. AB - Lytic infection of human parvovirus B19 (B19V) takes place exclusively in human erythroid progenitor cells of bone marrow and fetal liver, which disrupts erythropoiesis. During infection, B19V expresses three nonstructural proteins (NS1, 11-kDa, and 7.5-kDa) and two structural proteins (VP1 and VP2). While NS1 is essential for B19V DNA replication, the 11-kDa enhances viral DNA replication significantly. In this study, we confirmed the enhancement role of the 11-kDa in viral DNA replication and elucidated the underlying mechanism. We found that 11 kDa specially interacts with cellular growth factor receptor-bound protein 2 (Grb2) during virus infection and in vitro We determined a high affinity interaction between 11-kDa and Grb2 that has an equilibrium dissociation constant (KD) value of 18.13 nM. In vitro, one proline-rich motif was sufficient for 11 kDa to sustain a strong interaction with Grb2. In consistence, in vivo during infection, one proline-rich motif was enough for 11-kDa to significantly reduce phosphorylation of extracellular signal-regulated kinase (ERK). Mutations of all three proline-rich motifs of the 11-kDa abolished its capability to reduce ERK activity, and accordingly, decreased viral DNA replication. Transduction of a lentiviral vector encoding an shRNA targeting Grb2 decreased the expression of Grb2 as well as the level of ERK phosphorylation, which results in an increase of B19V replication. These results, in concert, indicate that the B19V 11-kDa interacts with cellular Grb2 to downregulate ERK activity, which upregulates viral DNA replication.SIGNIFICANCE Human parvovirus B19 (B19V) infection causes hematological disorders and is the leading cause of non-immunological fetal hydrops during pregnancy. During infection, B19V expresses two structural proteins VP1/VP2 and three nonstructural proteins, NS1, 11-kDa, and 7.5-kDa. While NS1 is essential, 11-kDa plays an enhancing role in viral DNA replication. Here we elucidated a mechanism underlying the 11-kDa regulated B19V DNA replication. 11-kDa is tightly associated with cellular growth factor receptor bound protein 2 (Grb2) during infection. In vitro, 11-kDa interacts with Grb2 at a high affinity through three proline-rich motifs, of which at least one is indispensable for the regulation of viral DNA replication. 11-kDa and Grb2 interaction disrupts the extracellular signal-regulated kinase (ERK) signaling, which mediates upregulation of B19V replication. Thus, our study reveals a novel mechanism of how a parvoviral small nonstructural protein regulates viral DNA replication through interacting with a host protein that is predominately expressed in the cytoplasm. PMID- 30282718 TI - The Abundant Tegument Protein pUL25 of Human Cytomegalovirus Prevents Proteasomal Degradation of pUL26 and Supports Its Suppression of ISGylation. AB - The tegument of human cytomegalovirus (HCMV) virions contains proteins that interfere with both the intrinsic and the innate immunity. One protein with a thus far unknown function is pUL25. The deletion of pUL25 in a viral mutant (Towne-DeltaUL25) had no impact on the release of virions and subviral dense bodies or on virion morphogenesis. Proteomic analyses showed few alterations in the overall protein composition of extracellular particles. A surprising result, however, was the almost complete absence of pUL26 in virions and dense bodies of Towne-DeltaUL25 and a reduction of the large isoform pUL26-p27 in mutant virus infected cells. pUL26 had been shown to inhibit protein conjugation with the interferon-stimulated gene 15 protein (ISG15), thereby supporting HCMV replication. To test for a functional relationship between pUL25 and pUL26, we addressed the steady-state levels of pUL26 and found them to be reduced in Towne DeltaUL25-infected cells. Coimmunoprecipitation experiments proved an interaction between pUL25 and pUL26. Surprisingly, the overall protein ISGylation was enhanced in Towne-DeltaUL25-infected cells, thus mimicking the phenotype of a pUL26-deleted HCMV mutant. The functional relevance of this was confirmed by showing that the replication of Towne-DeltaUL25 was more sensitive to beta interferon. The increase of protein ISGylation was also seen in cells infected with a mutant lacking the tegument protein pp65. Upon retesting, we found that pUL26 degradation was also increased when pp65 was unavailable. Our experiments show that both pUL25 and pp65 regulate pUL26 degradation and the pUL26-dependent reduction of ISGylation and add pUL25 as another HCMV tegument protein that interferes with the intrinsic immunity of the host cell.IMPORTANCE Human cytomegalovirus (HCMV) expresses a number of tegument proteins that interfere with the intrinsic and the innate defense mechanisms of the cell. Initial induction of the interferon-stimulated gene 15 protein (ISG15) and conjugation of proteins with ISG15 (ISGylation) by HCMV infection are subsequently attenuated by the expression of the viral IE1, pUL50, and pUL26 proteins. This study adds pUL25 as another factor that contributes to suppression of ISGylation. The tegument protein interacts with pUL26 and prevents its degradation by the proteasome. By doing this, it supports its restrictive influence on ISGylation. In addition, a lack of pUL25 enhances the levels of free ISG15, indicating that the tegument protein may interfere with the interferon response on levels other than interacting with pUL26. Knowledge obtained in this study widens our understanding of HCMV immune evasion and may also provide a new avenue for the use of pUL25 negative strains for vaccine production. PMID- 30282720 TI - CORRIGENDUM. PMID- 30282721 TI - Interactive effect between ATPase-related genes and early-life tobacco smoke exposure on bronchial hyper-responsiveness detected in asthma-ascertained families. AB - BACKGROUND: A positional cloning study of bronchial hyper-responsiveness (BHR) at the 17p11 locus in the French Epidemiological study on the Genetics and Environment of Asthma (EGEA) families showed significant interaction between early-life environmental tobacco smoke (ETS) exposure and genetic variants located in DNAH9. This gene encodes the heavy chain subunit of axonemal dynein, which is involved with ATP in the motile cilia function.Our goal was to identify genetic variants at other genes interacting with ETS in BHR by investigating all genes belonging to the 'ATP-binding' and 'ATPase activity' pathways which include DNAH9, are targets of cigarette smoke and play a crucial role in the airway inflammation. METHODS: Family-based interaction tests between ETS-exposed and unexposed BHR siblings were conducted in 388 EGEA families. Twenty single nucleotide polymorphisms (SNP) showing interaction signals (p<=5.10-3) were tested in the 253 Saguenay-Lac-Saint-Jean (SLSJ) families. RESULTS: One of these SNPs was significantly replicated for interaction with ETS in SLSJ families (p=0.003). Another SNP reached the significance threshold after correction for multiple testing in the combined analysis of the two samples (p=10-5). Results were confirmed using both a robust log-linear test and a gene-based interaction test. CONCLUSION: The SNPs showing interaction with ETS belong to the ATP8A1 and ABCA1 genes, which play a role in the maintenance of asymmetry and homeostasis of lung membrane lipids. PMID- 30282719 TI - Neutrophils instruct homeostatic and pathological states in naive tissues. AB - Immune protection relies on the capacity of neutrophils to infiltrate challenged tissues. Naive tissues, in contrast, are believed to remain free of these cells and protected from their toxic cargo. Here, we show that neutrophils are endowed with the capacity to infiltrate multiple tissues in the steady-state, a process that follows tissue-specific dynamics. By focusing in two particular tissues, the intestine and the lungs, we find that neutrophils infiltrating the intestine are engulfed by resident macrophages, resulting in repression of Il23 transcription, reduced G-CSF in plasma, and reinforced activity of distant bone marrow niches. In contrast, diurnal accumulation of neutrophils within the pulmonary vasculature influenced circadian transcription in the lungs. Neutrophil-influenced transcripts in this organ were associated with carcinogenesis and migration. Consistently, we found that neutrophils dictated the diurnal patterns of lung invasion by melanoma cells. Homeostatic infiltration of tissues unveils a facet of neutrophil biology that supports organ function, but can also instigate pathological states. PMID- 30282722 TI - Patient outcomes from time of listing for lung transplantation in the UK: are there disease-specific differences? AB - BACKGROUND: The demand for lung transplantation vastly exceeds the availability of donor organs. This translates into long waiting times and high waiting list mortality. We set out to examine factors influencing patient outcomes from the time of listing for lung transplantation in the UK, examining for differences by patient characteristics, lung disease category and transplant centre. METHODS: Data were obtained from the UK Transplant Registry held by NHS Blood and Transplant for adult lung-only registrations between 1January 2004 and 31 March 2014. Pretransplant and post-transplant outcomes were evaluated against lung disease category, blood group and height. RESULTS: Of the 2213 patient registrations, COPD comprised 28.4%, pulmonary fibrosis (PF) 26.2%, cystic fibrosis (CF) 25.4% and other lung pathologies 20.1%. The chance of transplantation after listing differed by the combined effect of disease category and centre (p<0.001). At 3 years postregistration, 78% of patients with COPD were transplanted followed by 61% of patients with CF, 59% of other lung pathology patients and 48% of patients with PF, who also had the highest waiting list mortality (37%). The chance of transplantation also differed by height with taller patients having a greater chance of transplant (HR: 1.03, 95% CI: 1.02 to 1.04, p<0.001). Patients with blood group O had the highest waiting mortality at 3 years postregistration compared with all other blood groups (27% vs 20%, p<0.001). CONCLUSIONS: The way donor lungs were allocated in the UK resulted in discrepancies between the risk profile and probability of lung transplantation. A new donor lung allocation scheme was introduced in 2017 to try to address these shortcomings. PMID- 30282723 TI - Phosphocreatine Levels in the Left Thalamus Decline during Wakefulness and Increase after a Nap. AB - Scientists have hypothesized that the availability of phosphocreatine (PCr) and its ratio to inorganic phosphate (Pi) in cerebral tissue form a substrate of wakefulness. It follows then, according to this hypothesis, that the exhaustion of PCr and the decline in the ratio of PCr to Pi form a substrate of fatigue. We used 31P-magnetic resonance spectroscopy (31P-MRS) to investigate quantitative levels of PCr, the gamma-signal of ATP, and Pi in 30 healthy humans (18 female) in the morning, in the afternoon, and while napping (n = 15) versus awake controls (n = 10). Levels of PCr (2.40 mM at 9 A.M.) decreased by 7.0 +/- 0.8% (p = 7.1 * 10-6, t = -5.5) in the left thalamus between 9 A.M. and 5 P.M. Inversely, Pi (0.74 mM at 9 A.M.) increased by 17.1 +/- 5% (p = 0.005, t = 3.1) and pH levels dropped by 0.14 +/- 0.07 (p = 0.002; t = 3.6). Following a 20 min nap after 5 P.M., local PCr, Pi, and pH were restored to morning levels. We did not find respective significant changes in the contralateral thalamus or in other investigated brain regions. Left hemispheric PCr was signficantly lower than right hemispheric PCr only at 5 P.M. in the thalamus and at all conditions in the temporal region. Thus, cerebral daytime-related and sleep-related molecular changes are accessible in vivo Prominent changes were identified in the thalamus. This region is heavily relied on for a series of energy-consuming tasks, such as the relay of sensory information to the cortex. Furthermore, our data confirm that lateralization of brain function is regionally dynamic and includes PCr.SIGNIFICANCE STATEMENT The metabolites phosphocreatine (PCr) and inorganic phosphate (Pi) are assumed to inversely reflect the cellular energy load. This study detected a diurnal decrease of intracellular PCr and a nap-associated reincrease in the left thalamus. Pi behaved inversely. This outcome corroborates the role of the thalamus as a region of high energy consumption in agreement with its function as a gateway that relays and modulates information flow. Conversely to the dynamic lateralization of thalamic PCr, a constantly significant lateralization was observed in other regions. Increasing fatigue over the course of the day may also be a matter of cerebral energy supply. Comparatively fast restoration of that supply may be part of the biological basis for the recreational value of "power napping."

AB - Magnetic resonance spectroscopy (MRS) measures the two most common inhibitory and excitatory neurotransmitters, GABA and glutamate, in the human brain. However, the role of MRS-derived GABA and glutamate signals in relation to system-level neural signaling and behavior is not fully understood. In this study, we investigated levels of GABA and glutamate in the visual cortex of healthy human participants (both genders) in three functional states with increasing visual input. Compared with a baseline state of eyes closed, GABA levels decreased after opening the eyes in darkness and Glx levels remained stable during eyes open but increased with visual stimulation. In relevant states, GABA and Glx correlated with amplitude of fMRI signal fluctuations. Furthermore, visual discriminatory performance correlated with the level of GABA, but not Glx. Our study suggests that differences in brain states can be detected through the contrasting dynamics of GABA and Glx, which has implications in interpreting MRS measurements.SIGNIFICANCE STATEMENT GABA and glutamate are the two most abundant neurotransmitters in human brain. Their interaction, known as inhibitory excitatory balance, plays a crucial role in establishing spontaneous and stimulus driven brain activity. Yet, the relationship between magnetic resonance spectroscopy (MRS)-derived levels of both metabolites and fMRI is still a matter of dispute. In this work, we study GABA and glutamate in three states of visual processing and in relation to fMRI and visual discriminatory performance in healthy people. We found that states of visual processing can be detected through the contrasting dynamics of GABA and glutamate and their correlation with fMRI signals. We also demonstrated that GABA, but not glutamate, in the visual system predicts visual performance. Our results provide insights into MRS-derived GABA and glutamate measurements. PMID- 30282725 TI - Nonlinear Lateral Interactions in V1 Population Responses Explained by a Contrast Gain Control Model. AB - How do cortical responses to local image elements combine to form a spatial pattern of population activity in primate V1? Here, we used voltage-sensitive dye imaging, which measures summed membrane potential activity, to examine the rules that govern lateral interactions between the representations of two small local oriented elements in macaque (Macaca mulatta) V1. We find strong subadditive and mostly orientation-independent interactions for nearby elements [2-4 mm interelement cortical distance (IED)] that gradually become linear at larger separations (>6 mm IED). These results are consistent with a population gain control model describing nonlinear V1 population responses to single oriented elements. However, because of the membrane potential-to-spiking accelerating nonlinearity, the model predicts supra-additive lateral interactions of spiking responses for intermediate separations at a range of locations between the two elements, consistent with some prior facilitatory effects observed in electrophysiology and psychophysics. Overall, our results suggest that population level lateral interactions in V1 are primarily explained by a simple orientation independent contrast gain control mechanism.SIGNIFICANCE STATEMENT Interactions between representations of simple visual elements such as oriented edges in primary visual cortex (V1) are thought to contribute to our ability to easily integrate contours and segment surfaces, but the mechanisms that govern these interactions are primarily unknown. Our study provides novel evidence that lateral interactions at the population level are governed by a simple contrast gain-control mechanism, and we show how this divisive gain-control mechanism can give rise to apparently facilitatory spiking responses. PMID- 30282726 TI - Nucleus Reuniens Is Required for Encoding and Retrieving Precise, Hippocampal Dependent Contextual Fear Memories in Rats. AB - The nucleus reuniens (RE) is a ventral midline thalamic nucleus that interconnects the medial prefrontal cortex (mPFC) and hippocampus (HPC). Considerable data indicate that HPC-mPFC circuits are involved in contextual and spatial memory; however, it is not clear whether the RE mediates the acquisition or retrieval of these memories. To examine this question, we inactivated the RE with muscimol before either the acquisition or retrieval of pavlovian fear conditioning in rats; freezing served as the index of fear. We found that RE inactivation before conditioning impaired the acquisition of contextual freezing, whereas inactivation of the RE before retrieval testing increased the generalization of freezing to a novel context; inactivation of the RE did not affect either the acquisition or expression of auditory fear conditioning. Interestingly, contextual conditioning impairments were absent when retrieval testing was also conducted after RE inactivation. Contextual memories acquired under RE inactivation were hippocampal independent, insofar as contextual freezing in rats conditioned under RE inactivation was insensitive to intrahippocampal infusions of the NMDA receptor antagonist aminophosphonovalerate. Together, these data reveal that the RE supports hippocampal-dependent encoding of precise contextual memories that allow discrimination of dangerous contexts from safe contexts. When the RE is inactive, however, alternate neural systems acquire an impoverished contextual memory that is expressed only when the RE is off-line.SIGNIFICANCE STATEMENT The midline thalamic nucleus reuniens (RE) coordinates communication between the hippocampus and medial prefrontal cortex, brain areas that are critical for contextual and spatial memory. Here we show that temporary pharmacological inactivation of RE impairs the acquisition and precision of contextual fear memories after pavlovian fear conditioning in rats. However, inactivating the RE before retrieval testing restored contextual memory in rats conditioned after RE inactivation. Critically, we show that imprecise contextual memories acquired under RE inactivation are learned independently of the hippocampus. These data reveal that the RE is required for hippocampal-dependent encoding of precise contextual memories to support the discrimination of safe and dangerous contexts. PMID- 30282727 TI - A Pool of Postnatally Generated Interneurons Persists in an Immature Stage in the Olfactory Bulb. AB - Calretinin (CR)-expressing periglomerular (PG) cells are the most abundant interneurons in the glomerular layer of the olfactory bulb. They are predominately generated postnatally from the septal and dorsal subventricular zones that continue producing them well into adulthood. Yet, little is known about their properties and functions. Using transgenic approaches and patch-clamp recording in mice of both sexes we show that CR(+) PG cells of both septal and dorsal origin have homogeneous morphological and electrophysiological properties. However, unlike other PG cells, these axonless neurons express a surprisingly small repertoire of voltage-activated channels and do not fire or fire at most a single and often small action potential. Moreover, they are not innervated by olfactory sensory neurons and receive little synaptic inputs from mitral or tufted cells at excitatory synapses where NMDA receptors predominate. These membrane and synaptic properties, that resemble those of newborn immature neurons not yet integrated in the network, persist over time and limit the recruitment of CR(+) PG cells by afferent inputs that strongly drive local network activity. Together, our results show that postnatally generated CR(+) PG cells continuously supply a large pool of neurons with unconventional properties. These data also question the contribution of CR(+) PG cells in olfactory bulb computation.SIGNIFICANCE STATEMENT Calretinin-expressing PG cells are by far the most abundant interneurons in the glomerular layer of the olfactory bulb. They are continuously produced during postnatal life, including adulthood, from neural stem cells located in the subventricular zones. Surprisingly, unlike other postnatally generated newborn neurons that quickly integrate into preexisting olfactory bulb networks, calretinin-expressing PG cells retain immature properties that limit their recruitment in local network activity for weeks, if not months, as if they would never fully mature. The function of this so far unsuspected pool of latent neurons is still unknown. PMID- 30282728 TI - Aggrecan Directs Extracellular Matrix-Mediated Neuronal Plasticity. AB - In the adult brain, the extracellular matrix (ECM) influences recovery after injury, susceptibility to mental disorders, and is in general a strong regulator of neuronal plasticity. The proteoglycan aggrecan is a core component of the condensed ECM structures termed perineuronal nets (PNNs), and the specific role of PNNs on neural plasticity remains elusive. Here, we genetically targeted the Acan gene encoding for aggrecan using a novel animal model. This allowed for conditional and targeted loss of aggrecan in vivo, which ablated the PNN structure and caused a shift in the population of parvalbumin-expressing inhibitory interneurons toward a high plasticity state. Selective deletion of the Acan gene in the visual cortex of male adult mice reinstated juvenile ocular dominance plasticity, which was mechanistically identical to critical period plasticity. Brain-wide targeting improved object recognition memory.SIGNIFICANCE STATEMENT The study provides the first direct evidence of aggrecan as the main functional constituent and orchestrator of perineuronal nets (PNNs), and that loss of PNNs by aggrecan removal induces a permanent state of critical period like plasticity. Loss of aggrecan ablates the PNN structure, resulting in invoked juvenile plasticity in the visual cortex and enhanced object recognition memory. PMID- 30282729 TI - Sleep and Wakefulness Are Controlled by Ventral Medial Midbrain/Pons GABAergic Neurons in Mice. AB - Sleep-wake behavior is controlled by a wide range of neuronal populations in the mammalian brain. Although the ventral midbrain/pons (VMP) area is suggested to participate in sleep-wake regulation, the neuronal mechanisms have remained unclear. Here, we found that nonspecific cell ablation or selective ablation of GABAergic neurons by expressing diphtheria toxin fragment A in the VMP in male mice induced a large increase in wakefulness that lasted at least 4 weeks. In contrast, selective ablation of dopaminergic neurons in the VMP had little effect on wakefulness. Chemogenetic inhibition of VMP GABAergic neurons also markedly increased wakefulness. The wake-promoting effect of the VMP GABAergic neuron ablation or inhibition was attenuated to varying degrees by the administration of dopamine D1 or D2/3 receptor antagonists and abolished by the administration of both antagonists together. In contrast, chemogenetic activation of VMP GABAergic neurons very strongly increased slow-wave sleep and reduced wakefulness. These findings suggest that VMP GABAergic neurons regulate dopaminergic actions in the sleep-wake behavior of mice.SIGNIFICANCE STATEMENT Current understanding of the neuronal mechanisms and populations that regulate sleep-wake behavior is incomplete. Here, we identified a GABAergic ventral midbrain/pons area that is necessary for controlling the daily amount of sleep and wakefulness in mice. We also found that these inhibitory neurons control wakefulness by suppressing dopaminergic systems. Surprisingly, activation of these neurons strongly induced slow-wave sleep while suppressing wakefulness. Our study reveals a new brain mechanism critical for sleep-wake regulation. PMID- 30282731 TI - Observing Action Sequences Elicits Sequence-Specific Neural Representations in Frontoparietal Brain Regions. AB - Learning new skills by watching others is important for social and motor development throughout the lifespan. Prior research has suggested that observational learning shares common substrates with physical practice at both cognitive and brain levels. In addition, neuroimaging studies have used multivariate analysis techniques to understand neural representations in a variety of domains, including vision, audition, memory, and action, but few studies have investigated neural plasticity in representational space. Therefore, although movement sequences can be learned by observing other people's actions, a largely unanswered question in neuroscience is how experience shapes the representational space of neural systems. Here, across a sample of male and female participants, we combined pretraining and posttraining fMRI sessions with 6 d of observational practice to determine whether the observation of action sequences elicits sequence-specific representations in human frontoparietal brain regions and the extent to which these representations become more distinct with observational practice. Our results showed that observed action sequences are modeled by distinct patterns of activity in frontoparietal cortex and that such representations largely generalize to very similar, but untrained, sequences. These findings advance our understanding of what is modeled during observational learning (sequence-specific information), as well as how it is modeled (reorganization of frontoparietal cortex is similar to that previously shown following physical practice). Therefore, on a more fine-grained neural level than demonstrated previously, our findings reveal how the representational structure of frontoparietal cortex maps visual information onto motor circuits in order to enhance motor performance.SIGNIFICANCE STATEMENT Learning by watching others is a cornerstone in the development of expertise and skilled behavior. However, it remains unclear how visual signals are mapped onto motor circuits for such learning to occur. Here, we show that observed action sequences are modeled by distinct patterns of activity in frontoparietal cortex and that such representations largely generalize to very similar, but untrained, sequences. These findings advance our understanding of what is modeled during observational learning (sequence-specific information), as well as how it is modeled (reorganization of frontoparietal cortex is similar to that previously shown following physical practice). More generally, these findings demonstrate how motor circuit involvement in the perception of action sequences shows high fidelity to prior work, which focused on physical performance of action sequences. PMID- 30282730 TI - Biphasic Modulation of NMDA Receptor Function by Metabotropic Glutamate Receptors. AB - A recently reported rapid potentiation of NMDA receptors by Group I metabotropic glutamate receptors (mGluRIs) via a Homer protein link is distinct from the classical, relatively slow inhibitory G-protein-associated signaling triggered by mGluRI activation. The relationship between these two mechanisms remains unknown. Here, we focused on the mGluRI-dependent modulation of NMDAR response in hippocampal dentate gyrus granule cells and cerebellar granule cells of C57BL6-J mice and found that these two contrasting mechanisms overlap competitively on the time scale from hundreds of milliseconds to seconds, with the net effect depending on the cell type. At a shorter time interval (units of millisecond), the Homer-mediated signal from mGluRIs prevails, causing upregulation of NMDAR function, in both dentate gyrus granule cells and cerebellar granule cells. Our results shed light on the possible mechanisms of anti-schizophrenia drugs that disrupt Homer-containing protein link.SIGNIFICANCE STATEMENT Here we study modulation of NMDA receptors triggered by activation of metabotropic glutamate receptors Group I via two distinct pathways: classical G-protein signaling system and newly discovered high-speed modulatory mechanism associated with Homer protein-containing direct molecular link. We found that these two contrasting mechanisms overlap competitively on the time scale from hundreds of milliseconds to seconds, with the net effect depending on the cell type. We have also found that both crosstalk mechanisms cause significant changes in synaptic strength and plasticity. Our results resolve an apparent discrepancy between earlier studies that demonstrated contradictive effects of Homer-containing protein link disruption on NMDA receptor signaling. On top of that, our data provide a plausible explanation for unclear action mechanisms of anti-schizophrenia drugs. PMID- 30282733 TI - Nonsaturating large magnetoresistance in semimetals. AB - The rapidly expanding class of quantum materials known as topological semimetals (TSMs) displays unique transport properties, including a striking dependence of resistivity on applied magnetic field, that are of great interest for both scientific and technological reasons. So far, many possible sources of extraordinarily large nonsaturating magnetoresistance have been proposed. However, experimental signatures that can identify or discern the dominant mechanism and connect to available theories are scarce. Here we present the magnetic susceptibility (chi), the tangent of the Hall angle ([Formula: see text]), along with magnetoresistance in four different nonmagnetic semimetals with high mobilities, NbP, TaP, NbSb2, and TaSb2, all of which exhibit nonsaturating large magnetoresistance (MR). We find that the distinctly different temperature dependences, [Formula: see text], and the values of [Formula: see text] in phosphides and antimonates serve as empirical criteria to sort the MR from different origins: NbP and TaP are uncompensated semimetals with linear dispersion, in which the nonsaturating magnetoresistance arises due to guiding center motion, while NbSb2 and TaSb2 are compensated semimetals, with a magnetoresistance emerging from nearly perfect charge compensation of two quadratic bands. Our results illustrate how a combination of magnetotransport and susceptibility measurements may be used to categorize the increasingly ubiquitous nonsaturating large magnetoresistance in TSMs. PMID- 30282732 TI - Abstract Representation of Prospective Reward in the Hippocampus. AB - Motivation enhances memory by increasing hippocampal engagement during encoding. However, whether such increased hippocampal activation reflects encoding of the value of highly rewarding events per se is less understood. Here, using a monetary incentive encoding task with a novel manipulation, we tested in humans whether the hippocampus represents abstract reward value, independent of perceptual content. During functional MRI scanning, men and women studied object pairs, each preceded by a monetary reward cue indicating the amount of money they would receive if they successfully remembered the object pair at test. Reward cues varied on both the level of reward (penny, dime, and dollar) and visual form (picture or word) across trials to dissociate hippocampal responses to reward value from those reflecting the perceptual properties of the cues. Behaviorally, participants remembered pairs associated with the high reward (dollar) more often than pairs associated with lower rewards. Neural pattern-similarity analysis revealed that hippocampal and parahippocampal cortex activation patterns discriminated between cues of different value regardless of their visual form, and that hippocampal discrimination of value was most pronounced in participants who showed the greatest behavioral sensitivity to reward. Strikingly, hippocampal patterns were most distinct for reward cues that differed in value but had similar visual appearance, consistent with theoretical proposals of hippocampal pattern differentiation of competing representations. Our data illustrate how contextual representations within the hippocampus go beyond space and time to include information about the motivational salience of events, with hippocampal reward coding tracking the motivational impact on later memory.SIGNIFICANCE STATEMENT Motivation, such as the promise of future rewards, enhances hippocampal engagement during encoding and promotes successful retention of events associated with valuable rewards. However, whether the hippocampus explicitly encodes reward value, dissociable from sensory information, is unclear. Here, we show that the hippocampus forms abstract representation of valuable rewards, encoding conceptual rather than perceptual information about the motivational context of individual events. Reward representation within the hippocampus is associated with preferential retention of high-value events in memory. Furthermore, we show that hippocampal-pattern differentiation serves to emphasize differences between visually similar events with distinct motivational salience. Collectively, these findings indicate that hippocampal contextual representations enable individuals to distinguish the motivational value of events, leading to prioritized encoding of significant memories. PMID- 30282734 TI - Raf kinase inhibitor protein negatively regulates FcepsilonRI-mediated mast cell activation and allergic response. AB - The signaling cascades triggered by the cross-linkage of immunoglobulin E (IgE) with its high-affinity receptor (FcepsilonRI) on mast cells contribute to multiple allergic disorders, such as asthma, rhinitis, and atopic dermatitis. Restraint of intracellular signals for mast cell activation is essential to restore homeostasis. In this study, we found that Raf kinase inhibitor protein (RKIP) negatively regulated mast cell activation. RKIP-deficient mast cells showed greater IgE-FcepsilonRI-mediated activation than wild-type mast cells. Consistently, RKIP deficiency in mast cells rendered mice more sensitive to IgE FcepsilonRI-mediated allergic responses and ovalbumin-induced airway inflammation. Mechanistically, RKIP interacts with the p85 subunit of PI3K, prevents it from binding to GRB2-associated binding protein 2 (Gab2), and eventually inhibits the activation of the PI3K/Akt/NF-kappaB complex and its downstream signaling. Furthermore, the expression of RKIP was significantly down regulated in the peripheral blood of asthma patients and in the IgE-FcepsilonRI stimulated mast cells. Collectively, our findings not only suggest that RKIP plays an important role in controlling mast cell-mediated allergic responses but also provide insight into therapeutic targets for mast cell-related allergic diseases. PMID- 30282735 TI - The ReFRAME library as a comprehensive drug repurposing library and its application to the treatment of cryptosporidiosis. AB - The chemical diversity and known safety profiles of drugs previously tested in humans make them a valuable set of compounds to explore potential therapeutic utility in indications outside those originally targeted, especially neglected tropical diseases. This practice of "drug repurposing" has become commonplace in academic and other nonprofit drug-discovery efforts, with the appeal that significantly less time and resources are required to advance a candidate into the clinic. Here, we report a comprehensive open-access, drug repositioning screening set of 12,000 compounds (termed ReFRAME; Repurposing, Focused Rescue, and Accelerated Medchem) that was assembled by combining three widely used commercial drug competitive intelligence databases (Clarivate Integrity, GVK Excelra GoStar, and Citeline Pharmaprojects), together with extensive patent mining of small molecules that have been dosed in humans. To date, 12,000 compounds (~80% of compounds identified from data mining) have been purchased or synthesized and subsequently plated for screening. To exemplify its utility, this collection was screened against Cryptosporidium spp., a major cause of childhood diarrhea in the developing world, and two active compounds previously tested in humans for other therapeutic indications were identified. Both compounds, VB-201 and a structurally related analog of ASP-7962, were subsequently shown to be efficacious in animal models of Cryptosporidium infection at clinically relevant doses, based on available human doses. In addition, an open-access data portal (https://reframedb.org) has been developed to share ReFRAME screen hits to encourage additional follow-up and maximize the impact of the ReFRAME screening collection. PMID- 30282737 TI - Oscillatory fluid flow drives scaling of contraction wave with system size. AB - Flows over remarkably long distances are crucial to the functioning of many organisms, across all kingdoms of life. Coordinated flows are fundamental to power deformations, required for migration or development, or to spread resources and signals. A ubiquitous mechanism to generate flows, particularly prominent in animals and amoebas, is actomyosin cortex-driven mechanical deformations that pump the fluid enclosed by the cortex. However, it is unclear how cortex dynamics can self-organize to give rise to coordinated flows across the largely varying scales of biological systems. Here, we develop a mechanochemical model of actomyosin cortex mechanics coupled to a contraction-triggering, soluble chemical. The chemical itself is advected with the flows generated by the cortex driven deformations of the tubular-shaped cell. The theoretical model predicts a dynamic instability giving rise to stable patterns of cortex contraction waves and oscillatory flows. Surprisingly, simulated patterns extend beyond the intrinsic length scale of the dynamic instability-scaling with system size instead. Patterns appear randomly but can be robustly generated in a growing system or by flow-generating boundary conditions. We identify oscillatory flows as the key for the scaling of contraction waves with system size. Our work shows the importance of active flows in biophysical models of patterning, not only as a regulating input or an emergent output, but also as a full part of a self organized machinery. Contractions and fluid flows are observed in all kinds of organisms, so this concept is likely to be relevant for a broad class of systems. PMID- 30282736 TI - Postnatal TrkB ablation in corticolimbic interneurons induces social dominance in male mice. AB - The tight balance between synaptic excitation and inhibition (E/I) within neocortical circuits in the mammalian brain is important for complex behavior. Many loss-of-function studies have demonstrated that brain-derived neurotrophic factor (BDNF) and its cognate receptor tropomyosin receptor kinase B (TrkB) are essential for the development of inhibitory GABAergic neurons. However, behavioral consequences of impaired BDNF/TrkB signaling in GABAergic neurons remain unclear, largely due to confounding motor function deficits observed in previous animal models. In this study, we generated conditional knockout mice (TrkB cKO) in which TrkB was ablated from a majority of corticolimbic GABAergic interneurons postnatally. These mice showed intact motor coordination and movement, but exhibited enhanced dominance over other mice in a group-housed setting. In addition, immature fast-spiking GABAergic neurons of TrkB cKO mice resulted in an E/I imbalance in layer 5 microcircuits within the medial prefrontal cortex (mPFC), a key region regulating social dominance. Restoring the E/I imbalance via optogenetic modulation in the mPFC of TrkB cKO mice normalized their social dominance behavior. Taken together, our results provide strong evidence for a role of BDNF/TrkB signaling in inhibitory synaptic modulation and social dominance behavior in mice. PMID- 30282738 TI - Grid-like hexadirectional modulation of human entorhinal theta oscillations. AB - The entorhinal cortex contains a network of grid cells that play a fundamental part in the brain's spatial system, supporting tasks such as path integration and spatial memory. In rodents, grid cells are thought to rely on network theta oscillations, but such signals are not evident in all species, challenging our understanding of the physiological basis of the grid network. We analyzed intracranial recordings from neurosurgical patients during virtual navigation to identify oscillatory characteristics of the human entorhinal grid network. The power of entorhinal theta oscillations showed six-fold modulation according to the virtual heading during navigation, which is a hypothesized signature of grid representations. Furthermore, modulation strength correlated with spatial memory performance. These results demonstrate the connection between theta oscillations and the human entorhinal grid network and show that features of grid-like neuronal representations can be identified from population electrophysiological recordings. PMID- 30282739 TI - Convergent evolution of complex structures for ant-bacterial defensive symbiosis in fungus-farming ants. AB - Evolutionary adaptations for maintaining beneficial microbes are hallmarks of mutualistic evolution. Fungus-farming "attine" ant species have complex cuticular modifications and specialized glands that house and nourish antibiotic-producing Actinobacteria symbionts, which in turn protect their hosts' fungus gardens from pathogens. Here we reconstruct ant-Actinobacteria evolutionary history across the full range of variation within subtribe Attina by combining dated phylogenomic and ultramorphological analyses. Ancestral-state analyses indicate the ant Actinobacteria symbiosis arose early in attine-ant evolution, a conclusion consistent with direct observations of Actinobacteria on fossil ants in Oligo Miocene amber. qPCR indicates that the dominant ant-associated Actinobacteria belong to the genus Pseudonocardia Tracing the evolutionary trajectories of Pseudonocardia-maintaining mechanisms across attine ants reveals a continuum of adaptations. In Myrmicocrypta species, which retain many ancestral morphological and behavioral traits, Pseudonocardia occur in specific locations on the legs and antennae, unassociated with any specialized structures. In contrast, specialized cuticular structures, including crypts and tubercles, evolved at least three times in derived attine-ant lineages. Conspicuous caste differences in Pseudonocardia-maintaining structures, in which specialized structures are present in worker ants and queens but reduced or lost in males, are consistent with vertical Pseudonocardia transmission. Although the majority of attine ants are associated with Pseudonocardia, there have been multiple losses of bacterial symbionts and bacteria-maintaining structures in different lineages over evolutionary time. The early origin of ant-Pseudonocardia mutualism and the multiple evolutionary convergences on strikingly similar anatomical adaptations for maintaining bacterial symbionts indicate that Pseudonocardia have played a critical role in the evolution of ant fungiculture. PMID- 30282741 TI - Private provision of public goods by environmental groups. AB - Many environmental nonprofit groups are assumed to provide public goods. While an extensive literature examines why donors join and give to nonprofits, none directly tests whether donations actually provide public goods. We seek such a test by using a common form of environmental organization: watershed groups. We find their increased presence resulted in lower dissolved oxygen deficiency and higher proportions of swimmable and fishable water bodies. Increased donations to and expenditures by the groups also improved water quality. Thus, private groups likely played a role in mitigating environmental problems. Overall, our results indicate private provision of a public good by nonprofit organizations. PMID- 30282740 TI - Intersexual conflict over seed size is stronger in more outcrossed populations of a mixed-mating plant. AB - In polyandrous species, fathers benefit from attracting greater maternal investment toward their offspring at the expense of the offspring of other males, while mothers should usually allocate resources equally among offspring. This conflict can lead to an evolutionary arms race between the sexes, manifested through antagonistic genes whose expression in offspring depends upon the parent of origin. The arms race may involve an increase in the strength of maternally versus paternally derived alleles engaged in a "tug of war" over maternal provisioning or repeated "recognition-avoidance" coevolution where growth enhancing paternally derived alleles evolve to escape recognition by maternal genes targeted to suppress their effect. Here, we develop predictions to distinguish between these two mechanisms when considering crosses among populations that have reached different equilibria in this intersexual arms race. We test these predictions using crosses within and among populations of Dalechampia scandens (Euphorbiaceae) that presumably have experienced different intensities of intersexual conflict, as inferred from their historical differences in mating system. In crosses where the paternal population was more outcrossed than the maternal population, hybrid seeds were larger than those normally produced in the maternal population, whereas when the maternal population was more outcrossed, hybrid seeds were smaller than normal. These results confirm the importance of mating systems in determining the intensity of intersexual conflict over maternal investment and provide strong support for a tug-of-war mechanism operating in this conflict. They also yield clear predictions for the fitness consequences of gene flow among populations with different mating histories. PMID- 30282742 TI - Intergroup social influence on emotion processing in the brain. AB - Emotions usually occur in a social context; yet little is known about how similar and dissimilar others influence our emotions. In the current study, we examined whether ingroup and outgroup members have differential influence on emotion processing at the behavioral and neural levels. To this end, we recruited 45 participants to rate a series of images displaying people engaged in different emotional contexts. Participants then underwent an fMRI scan where they viewed the same images along with information on how ingroup and outgroup members rated them, and they were asked to rate the images again. We found that participants shifted their emotions to be more in alignment with the ingroup over the outgroup, and that neural regions implicated in positive valuation [ventral striatum (VS) and ventromedial prefrontal cortex (vmPFC)], mentalizing [dorsomedial prefrontal cortex (dmPFC), medial prefrontal cortex (mPFC), posterior superior temporal sulcus (pSTS), and temporal pole], as well as emotion processing and salience detection (amygdala and insula), linearly tracked this behavior such that the extent of neural activity in these regions paralleled changes in participants' emotions. Results illustrate the powerful impact that ingroup members have on our emotions. PMID- 30282743 TI - Left/right asymmetric collective migration of parapineal cells is mediated by focal FGF signaling activity in leading cells. AB - The ability of cells to collectively interpret surrounding environmental signals underpins their capacity to coordinate their migration in various contexts, including embryonic development and cancer metastasis. One tractable model for studying collective migration is the parapineal, a left-sided group of neurons that arises from bilaterally positioned precursors that undergo a collective migration to the left side of the brain. In zebrafish, the migration of these cells requires Fgf8 and, in this study, we resolve how FGF signaling correlates with-and impacts the migratory dynamics of-the parapineal cell collective. The temporal and spatial dynamics of an FGF reporter transgene reveal that FGF signaling is activated in only few parapineal cells usually located at the leading edge of the parapineal during its migration. Overexpressing a constitutively active Fgf receptor compromises parapineal migration in wild-type embryos, while it partially restores both parapineal migration and mosaic expression of the FGF reporter transgene in fgf8 -/- mutant embryos. Focal activation of FGF signaling in few parapineal cells is sufficient to promote the migration of the whole parapineal collective. Finally, we show that asymmetric Nodal signaling contributes to the restriction and leftwards bias of FGF pathway activation. Our data indicate that the first overt morphological asymmetry in the zebrafish brain is promoted by FGF pathway activation in cells that lead the collective migration of the parapineal to the left. This study shows that cell state differences in FGF signaling in front versus rear cells is required to promote migration in a model of FGF-dependent collective migration. PMID- 30282745 TI - Blue carbon: past, present and future, with emphasis on macroalgae. AB - Blue carbon did not originally include macroalgal ecosystems; however evidence is mounting that macroalgal ecosystems function in marine carbon sequestration. The great majority of present day marine macroalgal net primary productivity (NPP) involves haptophytic algae on eroding shores. For these organisms the long-term storage of particulate organic carbon involves export from the site of production of biomass that has evaded parasites and grazers, and that some of the exported biomass is sedimented and stored rather than being mineralized en route by detritivores (microbes and fauna). Export from eroding shores, and subsequent storage, of haptophytic marine macroalgal particulate organic carbon could have started by 1.6 Ga. Storage on depositing shores close to the site of NPP by rhizophytic macroalgae and then by rhizophytic coastal seagrasses, tidal marshes and mangroves began not less than 209 Ma ago. Future increases in surface ocean temperatures may bring tropical marine macroalgae to their upper temperature limit, while temperate marine macroalgae will migrate poleward, in both cases assuming that temperature increases faster than genetic adaptation to higher temperature. Increased CO2 in the surface ocean will generally favour uncalcified over calcified marine macroalgae. This results in decreased CO2 release from decreased calcification, as well as decreased ballasting by CaCO3 of exported particulate organic carbon resulting in decreasing sedimentation. While much more work is needed, the available information suggests that macroalgae play a significant role in marine organic carbon storage. PMID- 30282746 TI - Is callose required for silicification in plants? AB - The cell wall polymer callose catalyses the formation of silica in vitro and is heavily implicated in biological silicification in Equisetum (horsetail) and Arabidopsis (thale cress) in vivo Callose, a beta-1,3-glucan, is an ideal partner for silicification, because its amorphous structure and ephemeral nature provide suitable microenvironments to support the condensation of silicic acid into silica. Herein, using scanning electron microscopy, immunohistochemistry and fluorescence, we provide further evidence of the cooperative nature of callose and silica in biological silicification in rice, an important crop plant and known silica accumulator. These new data along with recently published research enable us to propose a model to describe the intracellular events that together determine callose-driven biological silicification. PMID- 30282744 TI - Abscisic acid-independent stomatal CO2 signal transduction pathway and convergence of CO2 and ABA signaling downstream of OST1 kinase. AB - Stomatal pore apertures are narrowing globally due to the continuing rise in atmospheric [CO2]. CO2 elevation and the plant hormone abscisic acid (ABA) both induce rapid stomatal closure. However, the underlying signal transduction mechanisms for CO2/ABA interaction remain unclear. Two models have been considered: (i) CO2 elevation enhances ABA concentrations and/or early ABA signaling in guard cells to induce stomatal closure and (ii) CO2 signaling merges with ABA at OST1/SnRK2.6 protein kinase activation. Here we use genetics, ABA reporter imaging, stomatal conductance, patch clamp, and biochemical analyses to investigate these models. The strong ABA biosynthesis mutants nced3/nced5 and aba2-1 remain responsive to CO2 elevation. Rapid CO2-triggered stomatal closure in PYR/RCAR ABA receptor quadruple and hextuple mutants is not disrupted but delayed. Time-resolved ABA concentration monitoring in guard cells using a FRET based ABA-reporter, ABAleon2.15, and ABA reporter gene assays suggest that CO2 elevation does not trigger [ABA] increases in guard cells, in contrast to control ABA exposures. Moreover, CO2 activates guard cell S-type anion channels in nced3/nced5 and ABA receptor hextuple mutants. Unexpectedly, in-gel protein kinase assays show that unlike ABA, elevated CO2 does not activate OST1/SnRK2 kinases in guard cells. The present study points to a model in which rapid CO2 signal transduction leading to stomatal closure occurs via an ABA-independent pathway downstream of OST1/SnRK2.6. Basal ABA signaling and OST1/SnRK2 activity are required to facilitate the stomatal response to elevated CO2 These findings provide insights into the interaction between CO2/ABA signal transduction in light of the continuing rise in atmospheric [CO2]. PMID- 30282747 TI - Fish in habitats with higher motorboat disturbance show reduced sensitivity to motorboat noise. AB - Anthropogenic noise can negatively impact many taxa worldwide. It is possible that in noisy, high-disturbance environments, the range and severity of impacts could diminish over time, but the influence of previous disturbance remains untested in natural conditions. This study demonstrates the effects of motorboat noise on the physiology of an endemic cichlid fish in Lake Malawi. Exposure to motorboats (driven 20-100 m from fish) and loudspeaker playback of motorboat noise both elevated the oxygen-consumption rate at a single lower-disturbance site, characterized by low historic and current motorboat activity. Repeating this assay at further lower-disturbance sites revealed a consistent effect of elevated oxygen consumption in response to motorboat disturbance. However, when similar trials were repeated at four higher-disturbance sites, no effect of motorboat exposure was detected. These results demonstrate that disturbance history can affect local population responses to noise. Action regarding noise pollution should consider the past, as well as the present, when planning for the future. PMID- 30282748 TI - Phylogenetic non-independence in rates of trait evolution. AB - Statistical non-independence of species' biological traits is recognized in most traits under selection. Yet, whether or not the evolutionary rates of such biological traits are statistically non-independent remains to be tested. Here, we test the hypothesis that phenotypic evolutionary rates are non-independent, i.e. contain phylogenetic signal, using empirical rates of evolution in three separate traits: body mass in mammals, beak shape in birds and bite force in amniotes. Specifically, we test if evolutionary rates are phylogenetically interdependent. We find evidence for phylogenetic signal in evolutionary rates in all three case studies. While phylogenetic signal diminishes deeper in time, this is reflective of statistical power owing to small sample and effect sizes. When effect size is large, e.g. owing to the presence of fossil tips, we detect high phylogenetic signals even in deeper time slices. Thus, we recommend that rates be treated as being non-independent throughout the evolutionary history of the group of organisms under study, and any summaries or analyses of rates through time including associations of rates with traits-need to account for the undesired effects of shared ancestry. PMID- 30282749 TI - HIV-1 Nef Hijacks Lck and Rac1 Endosomal Traffic To Dually Modulate Signaling Mediated and Actin Cytoskeleton-Mediated T Cell Functions. AB - Endosomal traffic of TCR and signaling molecules regulates immunological synapse formation and T cell activation. We recently showed that Rab11 endosomes regulate the subcellular localization of the tyrosine kinase Lck and of the GTPase Rac1 and control their functions in TCR signaling and actin cytoskeleton remodeling. HIV-1 infection of T cells alters their endosomal traffic, activation capacity, and actin cytoskeleton organization. The viral protein Nef is pivotal for these modifications. We hypothesized that HIV-1 Nef could jointly alter Lck and Rac1 endosomal traffic and concomitantly modulate their functions. In this study, we show that HIV-1 infection of human T cells sequesters both Lck and Rac1 in a pericentrosomal compartment in an Nef-dependent manner. Strikingly, the Nef induced Lck compartment contains signaling-competent forms (phosphorylated on key Tyr residues) of Lck and some of its downstream effectors, TCRzeta, ZAP70, SLP76, and Vav1, avoiding the proximal LAT adaptor. Importantly, Nef-induced concentration of signaling molecules was concomitant with the upregulation of several early and late T cell activation genes. Moreover, preventing the concentration of the Nef-induced Lck compartment by depleting the Rab11 effector FIP3 counteracted Nef-induced gene expression upregulation. In addition, Nef extensively sequesters Rac1 and downregulates Rac1-dependent actin cytoskeleton remodeling, thus reducing T cell spreading. Therefore, by modifying their endosomal traffic, Nef hijacks signaling and actin cytoskeleton regulators to dually modulate their functional outputs. Our data shed new light into the molecular mechanisms that modify T cell physiology during HIV-1 infection. PMID- 30282750 TI - B Cell-Intrinsic STING Signaling Triggers Cell Activation, Synergizes with B Cell Receptor Signals, and Promotes Antibody Responses. AB - Generation of protective immune responses requires coordinated stimulation of innate and adaptive immune responses. An important mediator of innate immunity is stimulator of IFN genes (STING, MPYS, MITA), a ubiquitously but differentially expressed adaptor molecule that functions in the relay of signals initiated by sensing of cytosolic DNA and bacterial cyclic dinucleotides (CDNs). Whereas systemic expression of STING is required for CDN-aided mucosal Ab responses, its function in B cells in particular is unclear. In this study, we show that B cells can be directly activated by CDNs in a STING-dependent manner in vitro and in vivo. Direct activation of B cells by CDNs results in upregulation of costimulatory molecules and cytokine production and this can be accompanied by caspase-dependent cell death. CDN-induced cytokine production by B cells and other cell types also contributes to activation and immune responses. Type I IFN is primarily responsible for this indirect stimulation although other cytokines may contribute. BCR and STING signaling pathways act synergistically to promote Ab responses independent of type I IFN. B cell expression of STING is required for optimal in vivo IgG and mucosal IgA Ab responses induced by T cell-dependent Ags and cyclic-di-GMP but plays no discernable role in Ab responses in which alum is used as an adjuvant. Thus, STING functions autonomously in B cells responding to CDNs, and its activation synergizes with Ag receptor signals to promote B cell activation. PMID- 30282752 TI - VASP Regulates NK Cell Lytic Granule Convergence. AB - NK cells eliminate viral-infected and malignant cells through a highly orchestrated series of cytoskeletal rearrangements, resulting in the release of cytolytic granule contents toward the target cell. Central to this process is the convergence of cytolytic granules to a common point, the microtubule-organizing center (MTOC), before delivery to the synapse. In this study, we show that vasodialator-stimulated phosphoprotein (VASP), an actin regulatory protein, localizes to the cytolytic synapse, but surprisingly, shows no impact on conjugate formation or synaptic actin accumulation despite being required for human NK cell-mediated killing. Interestingly, we also find that a pool of VASP copurifies with lytic granules and localizes with lytic granules at the MTOC. Significantly, depletion of VASP decreased lytic granule convergence without impacting MTOC polarization. Using the KHYG-1 cell line in which lytic granules are in a constitutively converged state, we find that either VASP depletion or F actin destabilization promoted spreading of formerly converged granules. Our results demonstrate a novel requirement for VASP and actin polymerization in maintaining lytic granule convergence during NK cell-mediated killing. PMID- 30282751 TI - IL-2/CD25: A Long-Acting Fusion Protein That Promotes Immune Tolerance by Selectively Targeting the IL-2 Receptor on Regulatory T Cells. AB - Low-dose IL-2 represents an immunotherapy to selectively expand regulatory T cells (Tregs) to promote tolerance in patients with autoimmunity. In this article, we show that a fusion protein (FP) of mouse IL-2 and mouse IL-2Ralpha (CD25), joined by a noncleavable linker, has greater in vivo efficacy than rIL-2 at Treg expansion and control of autoimmunity. Biochemical and functional studies support a model in which IL-2 interacts with CD25 in the context of this FP in trans to form inactive head-to-tail dimers that slowly dissociate into an active monomer. In vitro, IL-2/CD25 has low sp. act. However, in vivo IL-2/CD25 is long lived to persistently and selectively stimulate Tregs. In female NOD mice, IL 2/CD25 administration increased Tregs within the pancreas and reduced the instance of spontaneous diabetes. Thus, IL-2/CD25 represents a distinct class of IL-2 FPs with the potential for clinical development for use in autoimmunity or other disorders of an overactive immune response. PMID- 30282753 TI - A Novel Neutralizing Antibody Specific to the DE Loop of VP1 Can Inhibit EV-D68 Infection in Mice. AB - Enterovirus D68 (EV-D68) belongs to the picornavirus family and was first isolated in CA, USA, in 1962. EV-D68 can cause severe cranial nerve system damage such as flaccid paralysis and acute respiratory diseases such as pneumonia. There are currently no efficient therapeutic methods or effective prophylactics. In this study, we isolated the mAb A6-1 from an EV-D68-infected rhesus macaque (Macaca mulatta) and found that the Ab provided effective protection in EV-D68 intranasally infected suckling mice. We observed that A6-1 bound to the DE loop of EV-D68 VP1 and interfered with the interaction between the EV-D68 virus and alpha2,6-linked sialic acids of the host cell. The production of A6-1 and its Ab properties present a bridging study for EV-D68 vaccine design and provide a tool for analyzing the process by which Abs can inhibit EV-D68 infection.

PMID- 30282758 TI - Pathogen evolution in finite populations: slow and steady spreads the best. AB - The theory of life-history evolution provides a powerful framework to understand the evolutionary dynamics of pathogens. It assumes, however, that host populations are large and that one can neglect the effects of demographic stochasticity. Here, we expand the theory to account for the effects of finite population size on the evolution of pathogen virulence. We show that demographic stochasticity introduces additional evolutionary forces that can qualitatively affect the dynamics and the evolutionary outcome. We discuss the importance of the shape of the pathogen fitness landscape on the balance between mutation, selection and genetic drift. This analysis reconciles Adaptive Dynamics with population genetics in finite populations and provides a new theoretical toolbox to study life-history evolution in realistic ecological scenarios. PMID- 30282755 TI - A Computational Modeling Approach Predicts Interaction of the Antifungal Protein AFP from Aspergillus giganteus with Fungal Membranes via Its gamma-Core Motif. AB - Fungal pathogens kill more people per year globally than malaria or tuberculosis and threaten international food security through crop destruction. New sophisticated strategies to inhibit fungal growth are thus urgently needed. Among the potential candidate molecules that strongly inhibit fungal spore germination are small cationic, cysteine-stabilized proteins of the AFP family secreted by a group of filamentous Ascomycetes. Its founding member, AFP from Aspergillus giganteus, is of particular interest since it selectively inhibits the growth of filamentous fungi without affecting the viability of mammalian, plant, or bacterial cells. AFPs are also characterized by their high efficacy and stability. Thus, AFP can serve as a lead compound for the development of novel antifungals. Notably, all members of the AFP family comprise a gamma-core motif which is conserved in all antimicrobial proteins from pro- and eukaryotes and known to interfere with the integrity of cytoplasmic plasma membranes. In this study, we used classical molecular dynamics simulations combined with wet laboratory experiments and nuclear magnetic resonance (NMR) spectroscopy to characterize the structure and dynamical behavior of AFP isomers in solution and their interaction with fungal model membranes. We demonstrate that the gamma-core motif of structurally conserved AFP is the key for its membrane interaction, thus verifying for the first time that the conserved gamma-core motif of antimicrobial proteins is directly involved in protein-membrane interactions. Furthermore, molecular dynamic simulations suggested that AFP does not destroy the fungal membrane by pore formation but covers its surface in a well-defined manner, using a multistep mechanism to destroy the membranes integrity.IMPORTANCE Fungal pathogens pose a serious danger to human welfare since they kill more people per year than malaria or tuberculosis and are responsible for crop losses worldwide. The treatment of fungal infections is becoming more complicated as fungi develop resistances against commonly used fungicides. Therefore, discovery and development of novel antifungal agents are of utmost importance. PMID- 30282760 TI - RT-QuIC: a new test for sporadic CJD. AB - The diagnosis of sporadic Creutzfeldt-Jakob disease (CJD) can be difficult, but the real-time quaking-induced conversion (RT-QuIC) assays have made a considerable impact on its clinical diagnosis. This technique exploits the ability of the misfolded pathological form of prion protein (PrPSc) found in cerebrospinal fluid (CSF) to induce conversion of normal PrP to the misfolded form, which subsequently aggregates. The formation of these aggregates of misfolded PrP is monitored in real time using fluorescent dyes. The current sensitivity of CSF RT-QuIC undertaken at the UK National CJD Research & Surveillance Unit is 92% and the specificity is 100%. The interpretation of the RT-QuIC traces is affected by the presence of raised CSF red and white cells counts and elevated total protein concentrations. We recommend that CSF samples for RT-QuIC analysis are clear and colourless with a white cell count of <10 x10^6/L and have a total protein concentration of <1 g/L. PMID- 30282756 TI - Highly Reduced Genome of the New Species Mycobacterium uberis, the Causative Agent of Nodular Thelitis and Tuberculoid Scrotitis in Livestock and a Close Relative of the Leprosy Bacilli. AB - Nodular thelitis is a chronic enzootic infection affecting dairy cows and goats. The causative agent was recently shown to be related to the leprosy-causing bacilli Mycobacterium leprae and Mycobacterium lepromatosis In this study, the genome of this pathogen was sequenced and analyzed. Phylogenomic analyses confirmed that the pathogen present in nodular thelitis and tuberculoid scrotitis is a distinct species related to the leprosy bacilli and Mycobacterium haemophilum Because the pathogen was originally isolated from a bovine udder, it was named "Mycobacterium uberis" The genome of "M. uberis" is only 3.12 Mb in length, which represents the smallest mycobacterial genome identified so far but which is close to that of leprosy bacilli in size. The genome contains 1,759 protein-coding genes and 1,081 pseudogenes, indicative of extensive reductive evolution and likely the reason that M. uberis cannot be grown axenically. The pseudogenization and genome reduction in M. uberis seem to have been to some extent independent from the results determined for the genomes of the leprosy bacilli.IMPORTANCE M. uberis is an emerging skin pathogen in dairy animals. Its genome underwent massive reduction and gene decay, leading to a minimal set of genes required for an obligatory intracellular lifestyle, which highly resembles the evolution of the leprosy agents M. leprae and M. lepromatosis The genomic similarity between M. uberis and the leprosy bacilli can help in identifying key virulence factors of these closely related species or in identifying genes responsible for the distinct differences between thelitis or scrotitis and leprosy with respect to clinical manifestations. Specific DNA markers can now be developed for quick detection of this pathogen. PMID- 30282759 TI - Lessons from pressure denaturation of proteins. AB - Although it is now relatively well understood how sequence defines and impacts global protein stability in specific structural contexts, the question of how sequence modulates the configurational landscape of proteins remains to be defined. Protein configurational equilibria are generally characterized by using various chemical denaturants or by changing temperature or pH. Another thermodynamic parameter which is less often used in such studies is high hydrostatic pressure. This review discusses the basis for pressure effects on protein structure and stability, and describes how the unique mechanisms of pressure-induced unfolding can provide unique insights into protein conformational landscapes.

AB - Neurocysticercosis is the most common parasitic neurological disease worldwide, yet in Europe, it remains relatively uncommon, with many practitioners rarely seeing a case. However, immigration and international travel mean that it is becoming increasingly recognised and diagnosed in developed countries. Being a treatable condition, it is essential to be familiar with the diagnosis and to appreciate its mimics and breadth of its possible clinical presentations. PMID- 30282763 TI - Can compressive thoracic cord lesions cause a pure lower motor neurone syndrome? AB - Compressive lesions of the spinal cord usually cause a syndrome of upper motor neurone weakness, spasticity and sensory loss below the level of the lesion. It has long been recognised that compressive cervical cord lesions may present as isolated lower motor neurone weakness of the upper limbs, a syndrome termed cervical spondylotic amyotrophy. We describe two patients presenting with isolated lower motor neurone weakness of the lower limbs in association with a compressive cord lesion at T11/12, a condition we have termed thoracic spondylotic amyotrophy. PMID- 30282764 TI - Lyme disease: diagnosis and management. AB - Lyme disease (borreliosis) is a tick-borne bacterial infection caused by the spirochaete Borrelia burgdoferi, transmitted by hard-backed Ixodes ticks. Actual numbers of cases are increasing and it appears that the distribution across the UK is widening; however, it occurs most frequently in area of woodland, with temperate climate. It typically presents in mid to late summer. Lyme disease is a multisystem disease. The nervous system is the second most commonly affected system after the skin. Other systemic manifestations, such as carditis, keratitis, uveitis and inflammatory arthritis, rarely occur in European Lyme disease. In 2018, the National Institute for Health and Care Excellence has updated its guidelines on the diagnosis and management of Lyme disease. Here, we highlight important aspects of this guidance and provide a more detailed review of the clinical spectrum of neuroborreliosis, illustrated by cases we have seen.

PMID- 30282769 TI - Sleep duration and risk of incident stroke by age, sex, and race: The REGARDS study. AB - OBJECTIVE: To investigate the association between reported sleep duration and incident stroke in a US cohort of black and white adults, and evaluate race, age, and sex as potential effect modifiers. METHODS: From 2008 to 2010, 16,733 black and white adults, aged >=45 years, without a history of stroke or sleep disordered breathing from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, reported their habitual sleep duration (<6, 6.0-6.9, 7.0 8.9 [reference], >=9 hours). Incident strokes were identified through biannual participant contact followed by physician adjudication of medical records. Cox proportional hazards analysis was conducted to calculate hazard ratios of interactions between sleep duration with race, age, sex, and 2-way combinations of these factors on incident stroke adjusting for stroke risk factors and sleep disordered breathing risk. RESULTS: The sample comprised 10.4% (n = 1,747) short sleepers (<6 hours) and 6.8% (n = 1,134) long sleepers (>=9 hours). Over an average 6.1 years follow-up, 460 strokes occurred. There were significant interactions between sleep duration and race (p = 0.018) and sleep duration and race-sex groups (p = 0.0023) in association with incident stroke. Short sleep duration was significantly associated with decreased risk for stroke among black participants (hazard ratio [HR] 0.49 [95% confidence interval (CI) 0.28-0.85]), particularly black men (HR 0.21 [95% CI 0.07-0.69]), whereas long sleep duration was significantly associated with increased risk for stroke among white men (HR 1.71 [95% CI 1.06-2.76]). CONCLUSIONS: The association of sleep duration with incident stroke differs by race and sex, with short sleep duration among black men associated with decreased risk, whereas long sleep duration among white men associated with increased risk for stroke. PMID- 30282770 TI - Racial differences in recurrent ischemic stroke risk and recurrent stroke case fatality. AB - OBJECTIVE: To determine black-white differences in 1-year recurrent stroke and 30 day case fatality after a recurrent stroke in older US adults. METHODS: We conducted a retrospective cohort study using a 5% random sample of Medicare beneficiaries with fee-for-service health insurance coverage who were hospitalized for ischemic stroke between 1999 and 2013. Hazard ratios for recurrent ischemic stroke and risk ratios for 30-day case fatality comparing blacks to whites were calculated with adjustment for demographics, risk factors, and competing risk of death when appropriate. RESULTS: Among 128,789 Medicare beneficiaries having an ischemic stroke (mean age 80 years [SD 8 years], 60.4% male), 11.1% were black. The incidence rate of recurrent ischemic stroke per 1,000 person-years for whites and blacks was 108 (95% confidence interval [CI], 106-111) and 154 (95% CI 147-162) , respectively. The multivariable-adjusted hazard ratio for recurrent stroke among blacks compared with whites was 1.36 (95% CI 1.29-1.44). The case fatality after recurrent stroke for blacks and whites was 21% (95% CI 21%-22%) and 16% (95% CI 15%-18%), respectively. The multivariable adjusted relative risk for mortality within 30 days of a recurrent stroke among blacks compared with whites was 0.82 (95% CI 0.73-0.93). CONCLUSION: The risk of stroke recurrence among older Americans hospitalized for ischemic stroke is higher for blacks compared to whites, while 30-day case fatality after recurrent stroke remains lower for blacks. PMID- 30282772 TI - Imbalance of cortical facilitatory and inhibitory circuits underlies hyperexcitability in ALS. AB - OBJECTIVE: To determine the relative contribution of inhibitory and facilitatory circuits in the development of cortical hyperexcitability in amyotrophic lateral sclerosis (ALS). METHODS: In this cross-sectional study, cortical excitability was assessed in 27 patients with ALS, and results compared to 25 healthy controls. In addition, a novel neurophysiologic measure of cortical function, short-interval intracortical facilitation (SICF), was assessed reflecting activity of the facilitatory circuits. RESULTS: There was a significant increase in SICF (ALS -18.51 +/- 1.56%, controls -8.52 +/- 1.21%, p < 0.001) in patients with ALS that was accompanied by a reduction of short-interval intracortical inhibition (ALS 3.94 +/- 1.29%, controls 14.23 +/- 1.18%, p < 0.001) and cortical silent period duration (p = 0.034). The index of excitation, a biomarker reflecting the contribution of inhibitory and facilitatory circuit activity, was significantly increased in patients with ALS (82.79 +/- 6.01%) compared to controls (36.15 +/- 3.44, p < 0.001), suggesting a shift toward cortical excitation. Increased excitation correlated with upper motor neuron signs (R 2 = 0.235, p = 0.016) and greater functional disability as reflected by a correlation with the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised score (R 2 = 0.335, p = 0.002). CONCLUSIONS: The present study established that cortical hyperexcitability is a key contributor to ALS pathophysiology, mediated through dysfunction of inhibitory and facilitatory intracortical circuits. Therapies aimed at restoring the cortical inhibitory imbalance provide novel avenues for future therapeutic targets. PMID- 30282771 TI - Paraneoplastic neuronal intermediate filament autoimmunity. AB - OBJECTIVE: To describe paraneoplastic neuronal intermediate filament (NIF) autoimmunity. METHODS: Archived patient and control serum and CSF specimens were evaluated by tissue-based indirect immunofluorescence assay (IFA). Autoantigens were identified by Western blot and mass spectrometry. NIF specificity was confirmed by dual tissue section staining and 5 recombinant NIF-specific HEK293 cell-based assays (CBAs, for alpha-internexin, neurofilament light [NfL], neurofilament medium, or neurofilament heavy chain, and peripherin). NIF immunoglobulin Gs (IgGs) were correlated with neurologic syndromes and cancers. RESULTS: Among 65 patients, NIF-IgG-positive by IFA and CBAs, 33 were female (51%). Median symptom onset age was 62 years (range 18-88). Patients fell into 2 groups, defined by the presence of NfL-IgG (21 patients, who mostly had >=4 NIF IgGs detected) or its absence (44 patients, who mostly had <=2 NIF-IgGs detected). Among NfL-IgG-positive patients, 19/21 had >=1 subacute onset CNS disorders: cerebellar ataxia (11), encephalopathy (11), or myelopathy (2). Cancers were detected in 16 of 21 patients (77%): carcinomas of neuroendocrine lineage (10) being most common (small cell [5], Merkel cell [3], other neuroendocrine [2]). Two of 257 controls (0.8%, both with small cell carcinoma) were positive by both IFA and CBA. Five of 7 patients with immunotherapy data improved. By comparison, the 44 NfL-IgG-negative patients had findings of unclear significance: diverse nervous system disorders (p = 0.006), as well as limited (p = 0.003) and more diverse (p < 0.0001) cancer accompaniments. CONCLUSIONS: NIF IgG detection by IFA, with confirmatory CBA testing that yields a profile including NfL-IgG, defines a paraneoplastic CNS disorder (usually ataxia or encephalopathy) accompanying neuroendocrine lineage neoplasia.

PMID- 30282774 TI - Young adult susceptible non-smokers' and smokers' responses to capsule cigarettes. AB - BACKGROUND: Flavour capsule cigarette variants (FCVs), which allow users to customise their smoking experience and reduce the harshness of smoking, have captured an increasing share of many markets. We examined tobacco companies' argument that such product innovations aim simply to shift market share, by estimating smokers' and susceptible non-smokers' responses to FCVs. METHODS: We conducted an online survey of 425 smokers (daily and non-daily), susceptible non smokers (n=224) and former smokers (n=166) aged between 18 and 25. Restrpondents completed a choice experiment, a behavioural probability measure and a perception task. We analysed the choice data using a conditional logistic regression and a rank-ordered logistic regression, and the probability and perception data using t tests and descriptive statistics. RESULTS: Non-smokers preferred an FCV relative to an unflavoured cigarette, whereas the opposite was the case for smokers. Susceptible non-smokers and former smokers were more likely to try a fruit flavoured FCV than an unflavoured stick, while daily smokers were more likely than non-daily smokers to do the same. Susceptible non-smokers, former smokers and non-daily smokers also had more positive perceptions of FCVs relative to unflavoured sticks than did daily smokers. CONCLUSIONS: FCVs appeal more to non smokers than to smokers, and more to non-daily smokers than to daily smokers. They thus appear likely to recruit non-smokers and potentially increase overall smoking prevalence. Policy responses include ensuring standardised packaging legislation disallows FCVs by specifically regulating the appearance and design of tobacco products, or introducing bespoke regulation that addresses the threat posed by FCVs. PMID- 30282775 TI - Basic economic gap related to smoking: reconciling tobacco tax receipts and economic costs of smoking-attributable diseases. AB - BACKGROUND: Tobacco tax rates set by various governments are not based on the idea that tax receipts should cover the costs incurred by smoking. It can be assumed that tobacco tax receipts (TTR) differ from the costs of smoking. The aim is to determine the global basic economic gap (BEG) between TTR and the economic costs of smoking-attributable diseases (ECS). METHODS: BEG is described as the difference between the ECS and TTR. A total of 124 countries representing 94% of global tobacco consumption were included in the research by means of the creation of a database, the adjustment of input data and the identification of their intersection. RESULTS: The global BEG reaches US$1438 billion per year. The global ECS are US$1911 billion per year. The global TTR are US$473 billion per year and compensate for only one quarter of the ECS. Within countries with the highest consumption of cigarettes, especially the USA but also Russia and Germany, the proportion of the ECS covered by the TTR is even lower, although private health expenditures have been taken into account. CONCLUSIONS: Our findings suggest that tobacco taxes would have to be globally increased by more than four times on average in order to cover the ECS or between two and two-and-a half times if we take private health expenditures into account. The informational pressure concerning health risks associated with smoking aimed at reducing harmful consumption and improving global health can also be supported with these economic facts. PMID- 30282776 TI - Quantifying homologous proteins and proteoforms. AB - Many proteoforms - arising from alternative splicing, post-translational modifications (PTM), or paralogous genes - have distinct biological functions, such as histone PTM proteoforms. However, their quantification by existing bottom up mass-spectrometry (MS) methods is undermined by peptide-specific biases. To avoid these biases, we developed and implemented a first-principles model (HIquant ) for quantifying proteoform stoichiometries. We characterized when MS data allow inferring proteoform stoichiometries by HIquant and derived an algorithm for optimal inference. We applied this algorithm to infer proteoform stoichiometries in two experimental systems that supported rigorous bench marking: alkylated proteoforms spiked-in at known ratios and endogenous histone 3 PTM proteoforms quantified relative to internal heavy standards. When compared to the benchmarks, the proteoform stoichiometries interfered by HIquant without using external standards had relative error of 5 - 15% for simple proteoforms and 20 - 30% for complex proteoforms.

AB - Ca2+/calmodulin-dependent protein kinase II (CaMKII) and metabotropic glutamate receptor 5 (mGlu5) are critical signaling molecules in synaptic plasticity and learning/memory. Here, we demonstrate that mGlu5 is present in CaMKIIalpha complexes isolated from mouse forebrain. Further in vitro characterization showed that the membrane-proximal region of the C-terminal domain (CTD) of mGlu5a directly interacts with purified Thr286-autophosphorylated (activated) CaMKIIalpha However, the binding of CaMKIIalpha to this CTD fragment is reduced by the addition of excess Ca2+/calmodulin or by additional CaMKIIalpha autophosphorylation at non-Thr286 sites. Furthermore, in vitro binding of CaMKIIalpha is dependent on a tribasic residue motif Lys-Arg-Arg (KRR) at residues 866-868 of the mGlu5a-CTD, and mutation of this motif decreases the coimmunoprecipitation of CaMKIIalpha with full-length mGlu5a expressed in heterologous cells by about 50%. The KRR motif is required for two novel functional effects of coexpressing constitutively active CaMKIIalpha with mGlu5a in heterologous cells. First, cell-surface biotinylation studies showed that CaMKIIalpha increases the surface expression of mGlu5a Second, using Ca2+ fluorimetry and single-cell Ca2+ imaging, we found that CaMKIIalpha reduces the initial peak of mGlu5a-mediated Ca2+ mobilization by about 25% while doubling the relative duration of the Ca2+ signal. These findings provide new insights into the physical and functional coupling of these key regulators of postsynaptic signaling.

AB - : : media-1vid110.1542/5828370139001PEDS-VA_2018-0457Video Abstract BACKGROUND: Increased admissions of higher birth weight and less acutely ill infants to NICUs suggests that intensive care may be used inappropriately in these populations. We describe variation in use of NICU services by gestational age and NICU type. METHODS: Using the Vermont Oxford Network database of all NICU admissions, we assessed variation within predefined gestational age categories in the following proportions: admissions, initial NICU hospitalization days, high-acuity cases >=34 weeks' gestation, and short-stay cases >=34 weeks' gestation. High acuity was defined as follows: death, intubated assisted ventilation for >=4 hours, early bacterial sepsis, major surgery requiring anesthesia, acute transport to another center, hypoxic-ischemic encephalopathy or a 5-minute Apgar score <=3, or therapeutic hypothermia. Short stay was defined as an inborn infant staying 1 to 3 days with discharge from the hospital. RESULTS: From 2014 to 2016, 486 741 infants were hospitalized 9 657 508 days at 381 NICUs in the United States. The median proportions of admissions, initial hospitalized days, high-acuity cases, and short stays varied significantly by NICU types in almost all gestational age categories. Fifteen percent of the infants >=34 weeks were high acuity, and 10% had short stays. CONCLUSIONS: There is substantial variation in use among NICUs. A campaign to focus neonatal care teams on using the NICU wisely that addresses the appropriate use of intensive care for newborn infants and accounts for local context and the needs of families is needed. PMID- 30282783 TI - An Electronic Referral and Social Work Protocol to Improve Access to Mental Health Services. AB - BACKGROUND AND OBJECTIVES: The prevalence of mental health problems among adolescents in the United States is a major public health concern. However, the uptake of mental health treatment is low. Integrating behavioral health into primary care is 1 research-informed strategy to increase engagement in treatment. Facilitators of and barriers to implementation of integrated behavioral health in a pediatric primary care setting are not well delineated. METHODS: We examined the effectiveness of 2 mental health quality improvement strategies: an electronic referral and a social work follow-up protocol. We analyzed the following measures: uptake rate of first mental health appointments, overall use of mental health appointments, and first and overall mental health appointment show rate. RESULTS: Overall use rate improved after implementation of electronic referral, with 13 consecutive points above the median. First appointment show rates improved with a special cause run occurring after adding social work students to the mental health quality improvement team. First appointment show rate improved from a monthly average of 51% (November 2014 to March 2016) to 78% (April 2016 to December 2016). Use rate improved initially with increased efforts in assisting patients with scheduling; show rate improved more slowly after an emphasis on scheduling patients exhibiting treatment readiness. CONCLUSIONS: Findings suggest that a number of facilitators can increase the effective use of mental health services in an integrated adolescent clinical setting. These include an electronic referral through a shared electronic health record, multidisciplinary collaboration, and care management by social workers equipped with a variety of clinical and care coordination skills.

AB - We present data that concurs with the reported geographical expansion of scrub typhus outside the "Tsutsugamushi Triangle" and addition of Orientia chuto as a second species in the Orientia genus. Wild rodents were caught in Marigat, Baringo County, Kenya, and ectoparasites, including chiggers, were recovered. Rodent and chigger species were identified by taxonomic features. DNA was extracted from the chiggers and used to amplify and/or sequence the 47-kDa high temperature transmembrane protein (TSA47), the 56-kDa type-specific antigen (TSA56), and the 16S rRNA (rrs) Orientia genes. The main rodent hosts identified were Acomys wilsoni, Crocidura sp., and Mastomys natalensis, which accounted for 59.2% of the total collection. Of these, A. wilsoni and M. natalensis harbored most of the chiggers that belonged to the Neotrombicula and Microtrombicula genera. A pool of chiggers from one of M. natalensis was positive for Orientia by TSA47 PCR, but Orientia did not amplify with the TSA56 primers. On sequencing the 850 bp of the TSA47 gene, the closest phylogenetic relative was O. chuto, with 97.65% sequence homology compared to 84.63 to 84.76% for O. tsutsugamushi 16S rRNA deep sequencing also revealed O. chuto as the closest phylogenetic relative, with 99.75% sequence homology. These results and the existing immunological and molecular reports are strongly suggestive of the existence of Orientia species in Kenya. PMID- 30282789 TI - Blood Culture Results Reporting: How Fast Is Your Laboratory and Is Faster Better? AB - Blood cultures are one of the most common and most important tests performed in clinical microbiology laboratories. Variables and technology that improve and speed the recovery of blood stream pathogens have been published in the Journal of Clinical Microbiology since its inception in 1975. Despite the importance of blood cultures, little research has focused on the turnaround time of blood culture reports. In this issue of the Journal of Clinical Microbiology, Y. P. Tabak et al. (J Clin Microbiol 56:e00500-18, 2018, https://doi.org/10.1128/JCM.00500-18) report the results of an investigation of Gram stain, organism identification, and susceptibility report turnaround times for 165,593 blood cultures from 13 laboratories. These data provide a starting point for clinical laboratories to establish targets for blood culture result reporting. PMID- 30282788 TI - Does Size Matter? Comparison of Extraction Yields for Different-Sized DNA Fragments by Seven Different Routine and Four New Circulating Cell-Free Extraction Methods. AB - An element essential for PCR detection of microbial agents in many sample types is the extraction step, designed to purify nucleic acids. Despite the importance of this step, yields have not been extensively compared across methods to determine whether the method used contributes to quantitative differences and the lack of commutability seen with existing clinical methods. This may in part explain why plasma and blood viral load assays have proven difficult to standardize. Also, studies have identified small DNA fragments of <200 bp in plasma (cell-free DNA [cfDNA]), which may include significant quantities of viral DNA. Our study evaluated extraction yields for 11 commercially available extraction methods, including 4 new methods designed to isolate cfDNA. Solutions of DNA fragments with sizes ranging from 50 to 1,500 bp were extracted, and then the eluates were tested by droplet digital PCR to determine the DNA fragment yield for each method. The results demonstrated a wide range of extraction yields across the variety of methods/instruments used, with the 50- and 100-bp fragment sizes showing especially inconsistent quantitative results and poor yields of less than 20%. Slightly higher, more consistent yields were seen with 2 of the 4 circulating cell-free extraction kits. These results demonstrate a significant need for further evaluation of nucleic acid yields across the variety of extraction platforms and highlight the poor extraction yields of small DNA fragments by existing methods. Further work is necessary to determine the impact of this inconsistency across instruments and the relevance of the low yields for smaller DNA fragments in clinical virology testing.

AB - Background: Limited methods for colistin minimum inhibitory concentration (MIC) determination are available to clinical microbiology laboratories. The purpose of this study was to evaluate the accuracy of the colistin broth disk elution (CBDE) test as compared to broth microdilution (BMD) for identifying colistin MICs.Methods: CBDE was compared to colistin BMD using a collection of Gram negative bacilli tested at two U.S. microbiology laboratories. Isolates tested included 121 retrospective clinical isolates, 45 prospective clinical isolates, and 6 mcr-1 positive E. coli CBDE was performed with four, 10 ml cation-adjusted Mueller Hinton broth tubes per isolate, to which 0, 1, 2, and 4 colistin 10 ug disks were added, generating a final concentration of 0 (growth control), 1, 2 and 4 ug/mL in the tubes. MICs were evaluated visually and interpreted using CLSI breakpoints. Site 2 also compared CBDE to reference broth macrodilution (BMAD, n= 110 isolates).Results: Overall, CBDE yielded a categorical agreement (CA) and essential agreement (EA) of 98% and 99%, respectively, compared to colistin BMD. Very major errors occurred for mcr-1 producing strains with MICs that fluctuated on repeat testing from 2 to 4 ug/mL. All other isolates were in CA with BMD. CBDE versus BMAD had an EA of 100% and CA of 100%.Conclusions: Compared to currently used techniques, CBDE is an easy and practical method to perform colistin testing. Some mcr-1 isolates yielded MICs of 2 ug/mL by CBDE and 4 ug/mL by BMD. As such, isolates with colistin MICs of 2 ug/mL by CBDE should be confirmed by reference BMD and those with MIC >= 2 ug/mL should be evaluated for mcr genes.

AB - Quality improvement can be difficult to assess and monitor in palliative care due to the nature of the specialty. This essay investigates ways in which this is currently carried out by assessing the benefits of patient-centred outcome measures.

PMID- 30282793 TI - Role of clinical psychology in UK hospices. AB - OBJECTIVE: The National Institute of Clinical Excellence (NICE) (2004) guidance recommends a tiered approach to psychological care within cancer care. This includes the provision of Clinical Psychologists to support other professionals to deliver high-quality psychological care at levels 1 and 2 and to provide direct input to patients experiencing high levels of distress at level 4. However, little is known about the role of Clinical Psychology within UK Hospices currently. A survey of Clinical Psychologists working in this area was undertaken to address this gap in knowledge. METHODS: We conducted an anonymous online survey of Clinical Psychologists working in Hospice organisations across the UK. Recruitment was completed via professional networking groups, social media and by contacting UK Hospice organisations. The survey included quantitative and qualitative items about professionals' experience, how their input is organised, their roles and activities and their views on the valuable and challenging aspects of working in this setting. RESULTS: Eighteen Clinical Psychologists responded and there was considerable variance in how their roles were organised. The tasks undertaken by most respondents were direct work with and consultation for hospice patients, and teaching and training staff. However, the findings demonstrated that Clinical Psychologists can undertake a wide range of tasks and draw on a range of therapeutic approaches including Cognitive Behavioural Therapy, Acceptance and Commitment Therapy and Compassion Focused Therapy, in their hospice work. CONCLUSION: Our results provide an overview of the role of Clinical Psychology in UK Hospices and demonstrate the contribution that Psychologists can make to this field.

PMID- 30282796 TI - GP at Hand adverts were misleading to patients, watchdog rules. PMID- 30282794 TI - The Number of Meiotic Double-Strand Breaks Influences Crossover Distribution in Arabidopsis. AB - Meiotic recombination generates genetic diversity and ensures proper chromosome segregation. Recombination is initiated by the programmed formation of double strand breaks (DSBs) in chromosomal DNA by DNA Topoisomerase VI-A Subunit (SPO11), a topoisomerase-like enzyme. Repair of some DSBs leads to the formation of crossovers (COs). In most organisms, including plants, the number of DSBs greatly exceeds the number of COs and which DSBs become CO sites is tightly controlled. The CO landscape is affected by DNA sequence and epigenome features of chromosomes as well as by global mechanisms controlling recombination dynamics. The latter are poorly understood and their effects on CO distribution are not well elucidated. To study how recombination dynamics affects CO distribution, we engineered Arabidopsis thaliana plants to carry hypomorphic alleles of SPO11-1 Two independent transgenic lines showed ~30% and 40% reductions in DSB numbers, which were commensurate with the dosage of the SPO11-1 transcript. The reduction in DSB number resulted in proportional, although smaller, reductions of the number of COs. Most interestingly, CO distribution along the chromosomes was dramatically altered, with substantially fewer COs forming in pericentromeric chromosome regions. These results indicate that SPO11 activity, and the resulting DSB numbers are major factors shaping the CO landscape.

PMID- 30282798 TI - Pomalidomide, cyclophosphamide, and dexamethasone for relapsed multiple myeloma. AB - 200 000 individuals yearly with a 40% mortality rate. Although platelets are implicated in the progression of ALI/ARDS, their exact role remains undefined. Triggering receptor expressed in myeloid cells (TREM)-like transcript 1 (TLT-1) is found on platelets, binds fibrinogen, and mediates clot formation. We hypothesized that platelets use TLT-1 to manage the progression of ALI/ARDS. Here we retrospectively measure plasma levels of soluble TLT-1 (sTLT-1) from the ARDS Network clinical trial and show that patients whose sTLT-1 levels were >1200 pg/mL had nearly twice the mortality risk as those with <1200 pg/mL (P < .001). After correcting for confounding factors such as creatinine levels, Acute Physiology And Chronic Health Evaluation III scores, age, platelet counts, and ventilation volume, sTLT-1 remains significant, suggesting that sTLT-1 is an independent prognostic factor (P < .0001). These data point to a role for TLT-1 during the progression of ALI/ARDS. We use a murine lipopolysaccharide-induced ALI model and demonstrate increased alveolar bleeding, aberrant neutrophil transmigration and accumulation associated with decreased fibrinogen deposition, and increased pulmonary tissue damage in the absence of TLT-1. The loss of TLT-1 resulted in an increased proportion of platelet-neutrophil conjugates (43.73 +/- 24.75% vs 8.92 +/- 2.4% in wild-type mice), which correlated with increased neutrophil death. Infusion of sTLT-1 restores normal fibrinogen deposition and reduces pulmonary hemorrhage by 40% (P <= .001) and tissue damage by 25% (P <= .001) in vivo. Our findings suggest that TLT-1 uses fibrinogen to govern the transition between inflammation and hemostasis and facilitate controlled leukocyte transmigration during the progression of ARDS. PMID- 30282801 TI - Sirtuin 7-mediated deacetylation of WD repeat domain 77 (WDR77) suppresses cancer cell growth by reducing WDR77/PRMT5 transmethylase complex activity. AB - The histone transmethylase complex comprising WD repeat domain 77 (WDR77) and protein arginine methyltransferase 5 (PRMT5) catalyzes dimethylation of H4R3 (H4R3me2) and drives cancer cell proliferation and migration, but its regulation is not fully understood. Here, we report that sirtuin 7 (SIRT7) directly deacetylates WDR77 and that this deacetylation interferes with the WDR77-PRMT5 interaction and suppresses proliferation of human colon cancer HCT116 cells. Using co-expression in HEK293T cells and co-immunoprecipitation assays, we observed that SIRT7 deacetylates WDR77 at Lys-3 and Lys-243, which reduced of WDR77's interaction with PRMT5. More importantly, this reduction suppressed the transmethylase activity of the WDR77/PRMT5 complex, resulting in a reduction of the H4R3me2 modification. Rescue of the WDR77-KO HCT116 cells with a WDR77-2KR (K3R and K243R) variant yielded cell migration and proliferation rates that were significantly lower than those of WDR77-KO HCT116 cells rescued with WT WDR77. In summary, SIRT7 is a major deacetylase for WDR77, and SIRT7-mediated deacetylation of WDR77 at Lys-3 and Lys-243 weakens the WDR77-PRMT5 interaction and activity and thereby suppresses growth of cancer cells. PMID- 30282802 TI - OTUB1 non-catalytically stabilizes the E2 ubiquitin-conjugating enzyme UBE2E1 by preventing its autoubiquitination. AB - OTUB1 is a deubiquitinating enzyme that cleaves Lys-48-linked polyubiquitin chains and also regulates ubiquitin signaling through a unique, noncatalytic mechanism. OTUB1 binds to a subset of E2 ubiquitin-conjugating enzymes and inhibits their activity by trapping the E2~ubiquitin thioester and preventing ubiquitin transfer. The same set of E2s stimulate the deubiquitinating activity of OTUB1 when the E2 is not charged with ubiquitin. Previous studies have shown that, in cells, OTUB1 binds to E2-conjugating enzymes of the UBE2D (UBCH5) and UBE2E families, as well as to UBE2N (UBC13). Cellular roles have been identified for the interaction of OTUB1 with UBE2N and members of the UBE2D family, but not for interactions with UBE2E E2 enzymes. We report here a novel role for OTUB1-E2 interactions in modulating E2 protein ubiquitination. We observe that Otub1 -/- knockout mice exhibit late-stage embryonic lethality. We find that OTUB1 depletion dramatically destabilizes the E2-conjugating enzyme UBE2E1 (UBCH6) in both mouse and human OTUB1 knockout cell lines. Of note, this effect is independent of the catalytic activity of OTUB1, but depends on its ability to bind to UBE2E1. We show that OTUB1 suppresses UBE2E1 autoubiquitination in vitro and in cells, thereby preventing UBE2E1 from being targeted to the proteasome for degradation. Taken together, we provide evidence that OTUB1 rescues UBE2E1 from degradation in vivo. PMID- 30282803 TI - A helical LC3-interacting region mediates the interaction between the retroviral restriction factor Trim5alpha and mammalian autophagy-related ATG8 proteins. AB - The retroviral restriction factor tripartite motif-containing 5alpha (Trim5alpha) acts during the early postentry stages of the retroviral life cycle to block infection by a broad range of retroviruses, disrupting reverse transcription and integration. The mechanism of this restriction is poorly understood, but it has recently been suggested to involve recruitment of components of the autophagy machinery, including members of the mammalian autophagy-related 8 (ATG8) family involved in targeting proteins to the autophagosome. To better understand the molecular details of this interaction, here we utilized analytical ultracentrifugation to characterize the binding of six ATG8 isoforms and determined the crystal structure of the Trim5alpha Bbox coiled-coil region in complex with one member of the mammalian ATG8 proteins, autophagy-related protein LC3 B (LC3B). We found that Trim5alpha binds all mammalian ATG8s and that, unlike the typical LC3-interacting region (LIR) that binds to mammalian ATG8s through a beta-strand motif comprising approximately six residues, LC3B binds to Trim5alpha via the alpha-helical coiled-coil region. The orientation of the structure demonstrated that LC3B could be accommodated within a Trim5alpha assembly that can bind the retroviral capsid. However, mutation of the binding interface does not affect retroviral restriction. Comparison of the typical linear beta-strand LIR with our atypical helical LIR reveals a conservation of the presentation of residues that are required for the interaction with LC3B. This observation expands the range of LC3B-binding proteins to include helical binding motifs and demonstrates a link between Trim5alpha and components of the autophagosome. PMID- 30282804 TI - Structural basis of inactivation of Ras and Rap1 small GTPases by Ras/Rap1 specific endopeptidase from the sepsis-causing pathogen Vibrio vulnificus. AB - Multifunctional autoprocessing repeats-in-toxin (MARTX) toxins are secreted by Gram-negative bacteria and function as primary virulence-promoting macromolecules that deliver multiple cytopathic and cytotoxic effector domains into the host cytoplasm. Among these effectors, Ras/Rap1-specific endopeptidase (RRSP) catalyzes the sequence-specific cleavage of the Switch I region of the cellular substrates Ras and Rap1 that are crucial for host innate immune defenses during infection. To dissect the molecular basis underpinning RRSP-mediated substrate inactivation, we determined the crystal structure of an RRSP from the sepsis causing bacterial pathogen Vibrio vulnificus (VvRRSP). Structural and biochemical analyses revealed that VvRRSP is a metal-independent TIKI family endopeptidase composed of an N-terminal membrane-localization and substrate-recruitment domain (N lobe) connected via an inter-lobe linker to the C-terminal active site coordinating core beta-sheet-containing domain (C lobe). Structure-based mutagenesis identified the 2His/2Glu catalytic residues in the core catalytic domain that are shared with other TIKI family enzymes and that are essential for Ras processing. In vitro KRas cleavage assays disclosed that deleting the N lobe in VvRRSP causes complete loss of enzymatic activity. Endogenous Ras cleavage assays combined with confocal microscopy analysis of HEK293T cells indicated that the N lobe functions both in membrane localization via the first alpha-helix and in substrate assimilation by altering the functional conformation of the C lobe to facilitate recruitment of cellular substrates. Collectively, these results indicate that RRSP is a critical virulence factor that robustly inactivates Ras and Rap1 and augments the pathogenicity of invading bacteria via the combined effects of its N and C lobes. PMID- 30282805 TI - Transcriptional regulation of the matrix protein Shematrin-2 during shell formation in pearl oyster. AB - The molluscan shell is a fascinating biomineral consisting of a highly organized calcium carbonate composite. Biomineralization is elaborately controlled and involves several macromolecules, especially matrix proteins, but little is known about the regulatory mechanisms. The matrix protein Shematrin-2, expression of which peaks in the mantle tissues and in the shell components of the pearl oyster Pinctada fucata, has been suggested to be a key participant in biomineralization. Here, we expressed and purified Shematrin-2 from P. fucata and explored its function and transcriptional regulation. An in vitro functional assay revealed that Shematrin-2 binds the calcite, aragonite, and chitin components of the shell, decreases the rate of calcium carbonate deposition, and changes the morphology of the deposited crystal in the calcite crystallization system. Furthermore, we cloned the Shematrin-2 gene promoter, and analysis of its sequence revealed putative binding sites for the transcription factors CCAAT enhancer-binding proteins (Pf-C/EBPs) and nuclear factor-Y (NF-Y). Using transient co-transfection and reporter gene assays, we found that cloned and recombinantly expressed Pf-C/EBP-A and Pf-C/EBP-B greatly and dose-dependently up regulate the promoter activity of the Shematrin-2 gene. Importantly, Pf-C/EBP-A and Pf-C/EBP-B knockdowns decreased Shematrin-2 gene expression and induced changes in the inner-surface structures in prismatic layers that were similar to those of antibody-based Shematrin-2 inhibition. Altogether, our data reveal that the transcription factors Pf-C/EBP-A and Pf-C/EBP-B up-regulate the expression of the matrix protein Shematrin-2 during shell formation in P. fucata, improving our understanding of the transcriptional regulation of molluscan shell development at the molecular level. PMID- 30282807 TI - A complete bioconversion cascade for dehalogenation and denitration by bacterial flavin-dependent enzymes. AB - Halogenated phenol and nitrophenols are toxic compounds that are widely accumulated in the environment. Enzymes in the had operon from the bacterium Ralstonia pickettii DTP0602 have the potential for application as biocatalysts in the degradation of many of these toxic chemicals. HadA monooxygenase previously was identified as a two-component reduced FAD (FADH-)-utilizing monooxygenase with dual activities of dehalogenation and denitration. However, the partner enzymes of HadA, that is, the flavin reductase and quinone reductase that provide the FADH- for HadA and reduce quinone to hydroquinone, remain to be identified. In this report, we overexpressed and purified the flavin reductases, HadB and HadX, to investigate their functional and catalytic properties. Our results indicated that HadB is an FMN-dependent quinone reductase that converts the quinone products from HadA to hydroquinone compounds that are more stable and can be assimilated by downstream enzymes in the pathway. Transient kinetics indicated that HadB prefers NADH and menadione as the electron donor and acceptor, respectively. We found that HadX is an FAD-bound flavin reductase, which can generate FADH- for HadA to catalyze dehalogenation or denitration reactions. Thermodynamic and transient kinetic experiments revealed that HadX prefers to bind FAD over FADH- and that HadX can transfer FADH- from HadX to HadA via free diffusion. Moreover, HadX rapidly catalyzed NADH-mediated reduction of flavin and provided the FADH- for a monooxygenase of a different system. Combination of all three flavin-dependent enzymes, i.e. HadA/HadB/HadX, reconstituted an effective dehalogenation and denitration cascade, which may be useful for future bioremediation applications. PMID- 30282806 TI - Mechanistic insights into the interaction of the MOG1 protein with the cardiac sodium channel Nav1.5 clarify the molecular basis of Brugada syndrome. AB - Nav1.5 is the alpha-subunit of the cardiac sodium channel complex. Abnormal expression of Nav1.5 on the cell surface because of mutations that disrupt Nav1.5 trafficking causes Brugada syndrome (BrS), sick sinus syndrome (SSS), cardiac conduction disease, dilated cardiomyopathy, and sudden infant death syndrome. We and others previously reported that Ran-binding protein MOG1 (MOG1), a small protein that interacts with Nav1.5, promotes Nav1.5 intracellular trafficking to plasma membranes and that a substitution in MOG1, E83D, causes BrS. However, the molecular basis for the MOG1/Nav1.5 interaction and how the E83D substitution causes BrS remains unknown. Here, we assessed the effects of defined MOG1 deletions and alanine-scanning substitutions on MOG1's interaction with Nav1.5. Large deletion analysis mapped the MOG1 domain required for the interaction with Nav1.5 to the region spanning amino acids 146-174, and a refined deletion analysis further narrowed this domain to amino acids 146-155. Site-directed mutagenesis further revealed that Asp-148, Arg-150, and Ser-151 cluster in a peptide loop essential for binding to Nav1.5. GST pulldown and electrophysiological analyses disclosed that the substitutions E83D, D148Q, R150Q, and S151Q disrupt MOG1's interaction with Nav1.5 and significantly reduce its trafficking to the cell surface. Examination of MOG1's 3D structure revealed that Glu-83 and the loop containing Asp-148, Arg-150, and Ser-151 are spatially proximal, suggesting that these residues form a critical binding site for Nav1.5. In conclusion, our findings identify the structural elements in MOG1 that are crucial for its interaction with Nav1.5 and improve our understanding of how the E83D substitution causes BrS. PMID- 30282809 TI - Mathematical modeling reveals spontaneous emergence of self-replication in chemical reaction systems. AB - Explaining the origin of life requires us to elucidate how self-replication arises. To be specific, how can a self-replicating entity develop spontaneously from a chemical reaction system in which no reaction is self-replicating? Previously proposed mathematical models either supply an explicit framework for a minimal living system or consider only catalyzed reactions, and thus fail to provide a comprehensive theory. Here, we set up a general mathematical model for chemical reaction systems that properly accounts for energetics, kinetics, and the conservation law. We found that (1) some systems are collectively-catalytic, a mode whereby reactants are transformed into end products with the assistance of intermediates (as in the citric acid cycle), whereas some others are self replicating, that is, different parts replicate each other and the system self replicates as a whole (as in the formose reaction, in which sugar is replicated from formaldehyde); (2) side reactions do not always inhibit such systems; (3) randomly chosen chemical universes (namely, random artificial chemistries) often contain one or more such systems; (4) it is possible to construct a self replicating system in which the entropy of some parts spontaneously decreases, in a manner similar to that discussed by Schrodinger; and (5) complex self replicating molecules can emerge spontaneously and relatively easily from simple chemical reaction systems through a sequence of transitions. Together, these results start to explain the origins of prebiotic evolution. PMID- 30282808 TI - Endo-fucoidan hydrolases from glycoside hydrolase family 107 (GH107) display structural and mechanistic similarities to alpha-l-fucosidases from GH29. AB - Fucoidans are chemically complex and highly heterogeneous sulfated marine fucans from brown macro algae. Possessing a variety of physicochemical and biological activities, fucoidans are used as gelling and thickening agents in the food industry and have anticoagulant, antiviral, antitumor, antibacterial, and immune activities. Although fucoidan-depolymerizing enzymes have been identified, the molecular basis of their activity on these chemically complex polysaccharides remains largely uninvestigated. In this study, we focused on three glycoside hydrolase family 107 (GH107) enzymes: MfFcnA and two newly identified members, P5AFcnA and P19DFcnA, from a bacterial species of the genus Psychromonas Using carbohydrate-PAGE, we show that P5AFcnA and P19DFcnA are active on fucoidans that differ from those depolymerized by MfFcnA, revealing differential substrate specificity within the GH107 family. Using a combination of X-ray crystallography and NMR analyses, we further show that GH107 family enzymes share features of their structures and catalytic mechanisms with GH29 alpha-l-fucosidases. However, we found that GH107 enzymes have the distinction of utilizing a histidine side chain as the proposed acid/base catalyst in its retaining mechanism. Further interpretation of the structural data indicated that the active-site architectures within this family are highly variable, likely reflecting the specificity of GH107 enzymes for different fucoidan substructures. Together, these findings begin to illuminate the molecular details underpinning the biological processing of fucoidans. PMID- 30282810 TI - Aneuploidy in intestinal stem cells promotes gut dysplasia in Drosophila. AB - Aneuploidy is associated with different human diseases including cancer. However, different cell types appear to respond differently to aneuploidy, either by promoting tumorigenesis or causing cell death. We set out to study the behavior of adult Drosophila melanogaster intestinal stem cells (ISCs) after induction of chromosome missegregation either by abrogation of the spindle assembly checkpoint or through kinetochore disruption or centrosome amplification. These conditions induce moderate levels of aneuploidy in ISCs, and we find no evidence of apoptosis. Instead, we observe a significant accumulation of ISCs associated with increased stem cell proliferation and an excess of enteroendocrine cells. Moreover, aneuploidy causes up-regulation of the JNK pathway throughout the posterior midgut, and specific inhibition of JNK signaling in ISCs is sufficient to prevent dysplasia. Our findings highlight the importance of understanding the behavior of different stem cell populations to aneuploidy and how these can act as reservoirs for genomic alterations that can lead to tissue pathologies. PMID- 30282813 TI - Immune effector functions of human IgG2 antibodies against EGFR. AB - Three FDA approved epidermal growth factor receptor (EGFR) antibodies (Cetuximab, Panitumumab, Necitumumab) are clinically available to treat patients with different types of cancer. Interestingly, Panitumumab is of human IgG2 isotype, which is often considered to have limited immune effector functions. Unexpectedly, our studies unraveled that human IgG2 antibodies against EGFR mediated effective CDC when combined with another non cross-blocking EGFR antibody. This second antibody could be of human IgG1 or IgG2 isotype. Furthermore, EGFR antibodies of human IgG2 isotype were highly potent in recruiting myeloid effector cells such as M1 macrophages and PMN for tumor cell killing by ADCC. Tumor cell killing by PMN was more effective with IgG2 than with IgG1 antibodies if tumor cells expressed lower levels of EGFR. Additionally, lower expression levels of the "don't eat me" molecule CD47 on tumor cells enabeled ADCC also by M2 macrophages, and improved PMN and macrophage mediated ADCC. A TCGA enquiry revealed broadly varying CD47 expression levels across different solid tumor types. Together, these results demonstrate that human IgG2 antibodies against EGFR can promote significant Fc mediated effector functions, which may contribute to their clinical efficacy. The future challenge will be to identify clinical situations in which myeloid effector cells can optimally contribute to antibody efficacy.

We recently identified that Ewing sarcoma cells are uniquely vulnerable to inhibitors of ribonucleotide reductase (RNR), the rate-limiting enzyme in the synthesis of deoxyribonucleotides. We subsequently found that the inhibition of checkpoint kinase 1 (CHK1) increases the sensitivity of Ewing sarcoma cells to inhibitors of RNR, such as gemcitabine. However, Ewing sarcoma cells exhibit high levels of the CHK1 protein, which may represent an adaptive response to elevated levels of endogenous DNA replication stress. Consequently, we began this work with the aim of determining the impact of CHK1 levels on drug sensitivity, as well as identifying the mechanisms and pathways that regulate CHK1 levels in Ewing sarcoma cells. In this report, we show that the high levels of the CHK1 protein in Ewing sarcoma cells limit the efficacy of CHK1 inhibitors. However, inhibition of mTORC1/2 activates the translational repressor 4E-BP1, reduces protein synthesis, and decreases levels of the CHK1 protein in Ewing sarcoma cells. Similarly, we identified that the CHK1 inhibitor prexasertib also activates 4E-BP1, inhibits protein synthesis, and reduces CHK1 protein levels in Ewing sarcoma cells. Moreover, the combination of prexasertib and gemcitabine was synergistic in vitro, caused tumor regression in vivo, and significantly prolonged mouse survival in a Ewing sarcoma xenograft experiment. Overall, our results provide insight into Ewing sarcoma biology and support further investigation of the CHK1 pathway as a therapeutic target in Ewing sarcoma tumors. PMID- 30282811 TI - A Human Ribonuclease Variant and ERK-Pathway Inhibitors Exhibit Highly Synergistic Toxicity for Cancer Cells. AB - Pancreatic-type ribonucleases (ptRNases) are prevalent secretory enzymes that catalyze the cleavage of RNA. Ribonuclease inhibitor (RI) is a cytosolic protein that has femtomolar affinity for ptRNases, affording protection from the toxic catalytic activity of ptRNases, which can invade human cells. A human ptRNase variant that is resistant to inhibition by RI is a cytotoxin that is undergoing a clinical trial as a cancer chemotherapeutic agent. We find that the ptRNase and protein kinases in the ERK pathway exhibit strongly synergistic toxicity toward lung cancer cells (including a KRASG12C variant) and melanoma cells (including BRAFV600E variants). The synergism arises from inhibiting the phosphorylation of RI and thereby diminishing its affinity for the ptRNase. These findings link seemingly unrelated cellular processes, and suggest that the use of a kinase inhibitor to unleash a cytotoxic enzyme could lead to beneficial manifestations in the clinic. PMID- 30282814 TI - Association of Imatinib Plasma Concentration and Single-nucleotide Polymorphisms with Adverse Drug Reactions in Patients with Gastrointestinal Stromal Tumors. AB - Gastrointestinal stromal tumors (GIST) are the most prevalent mesenchymal tumors of the digestive tract. To investigate the association of imatinib mesylate plasma concentration with adverse drug reactions (ADRs) and influences of genetic polymorphisms on ADRs in GIST patients taking imatinib, a cohort of GIST patients consecutively treated with imatinib were included in the observational study. Clinical, pathologic and genotype information was recorded at enrollment and blood samples were collected at time as design. The plasma concentration of the imatinib was detected by LC-MS/MS. A questionnaire was used to evaluate the ADRs at each visit. SNPs in 13 genes were analyzed for a possible association with ADRs. The mean plasma trough concentration of 129 patients taking imatinib was 1.45 +/- 0.79 MUg/ml, average peak concentration was 2.63 +/- 1.07 MUg/ml. The imatinib concentration in patients treated with 600 mg/day was significantly higher than other dosage groups (P < 0.05). The ADRs were mostly mild. Edema, vomiting, and fatigue were significantly correlated with imatinib concentration (P < 0.05). Mutations of IL13 rs1800925 and CXCL14 rs7716492 were related with the incidence of leukopenia and rash in our research, separately (P < 0.05). We confirmed that with the increase of imatinib concentration, the incidence of edema, vomiting, and fatigue rises as well. Mutations of IL13 rs1800925 and CXCL14 rs7716492 may be the promising biomarkers to predict the ADRs of imatinib. The results of the study are of guiding significance for the use of imatinib in patients with GIST. PMID- 30282815 TI - Mast cells and neutrophils mediate peripheral motor pathway degeneration in ALS. AB - Neuroinflammation is a recognized pathogenic mechanism underlying motor neuron degeneration in amyotrophic lateral sclerosis (ALS), but the inflammatory mechanisms influencing peripheral motor axon degeneration remain largely unknown. A recent report showed a pathogenic role for c-Kit-expressing mast cells mediating inflammation and neuromuscular junction denervation in muscles from SOD1G93A rats. Here, we have explored whether mast cells infiltrate skeletal muscles in autopsied muscles from ALS patients. We report that degranulating mast cells were abundant in the quadriceps muscles from ALS subjects but not in controls. Mast cells were associated with myofibers and motor endplates and, remarkably, interacted with neutrophils forming large extracellular traps. Mast cells and neutrophils were also abundant around motor axons in the extensor digitorum longus muscle, sciatic nerve, and ventral roots of symptomatic SOD1G93A rats, indicating that immune cell infiltration extends along the entire peripheral motor pathway. Postparalysis treatment of SOD1G93A rats with the tyrosine kinase inhibitor drug masitinib prevented mast cell and neutrophil infiltration, axonal pathology, secondary demyelination, and the loss of type 2B myofibers, compared with vehicle-treated rats. These findings provide further evidence for a yet unrecognized contribution of immune cells in peripheral motor pathway degeneration that can be therapeutically targeted by tyrosine kinase inhibitors. PMID- 30282816 TI - Prelamin A causes aberrant myonuclear arrangement and results in muscle fiber weakness. AB - Physiological and premature aging are frequently associated with an accumulation of prelamin A, a precursor of lamin A, in the nuclear envelope of various cell types. Here, we aimed to underpin the hitherto unknown mechanisms by which prelamin A alters myonuclear organization and muscle fiber function. By experimentally studying membrane-permeabilized myofibers from various transgenic mouse lines, our results indicate that, in the presence of prelamin A, the abundance of nuclei and myosin content is markedly reduced within muscle fibers. This leads to a concept by which the remaining myonuclei are very distant from each other and are pushed to function beyond their maximum cytoplasmic capacity, ultimately inducing muscle fiber weakness. PMID- 30282818 TI - Maternal high-fat diet results in microbiota-dependent expansion of ILC3s in mice offspring. AB - Maternal obesity and a high-fat diet (HFD) during the perinatal period have documented short- and long-term adverse outcomes for offspring. However, the mechanisms of maternal HFD effects on neonatal offspring are unclear. While the effects of maternal HFD exposure during pregnancy on the offspring are increasingly being appreciated, we do not know if maternal HFD alters the microbiota or affects neonatal susceptibility to inflammatory conditions, nor the mechanisms involved. In this study, we show that the offspring of mothers exposed to HFD develop a unique microbiota, marked by expansion of Firmicutes, and an increase in IL-17-producing type 3 innate lymphoid cells (ILC3s). The expansion of ILC3s was recapitulated through neocolonization with HFD microbiota alone. Further, the HFD offspring were susceptible to a neonatal model of inflammation that was reversible with IL-17 blockade. Collectively, these data suggest a previously unknown and unique role for ILC3s in the promotion of an early inflammatory susceptibility in the offspring of mothers exposed to HFD. PMID- 30282817 TI - Gut microbiota-dependent modulation of innate immunity and lymph node remodeling affects cardiac allograft outcomes. AB - We hypothesized that the gut microbiota influences survival of murine cardiac allografts through modulation of immunity. Antibiotic pretreated mice received vascularized cardiac allografts and fecal microbiota transfer (FMT), along with tacrolimus immunosuppression. FMT source samples were from normal, pregnant (immune suppressed), or spontaneously colitic (inflammation) mice. Bifidobacterium pseudolongum (B. pseudolongum) in pregnant FMT recipients was associated with prolonged allograft survival and lower inflammation and fibrosis, while normal or colitic FMT resulted in inferior survival and worse histology. Transfer of B. pseudolongum alone resulted in reduced inflammation and fibrosis. Stimulation of DC and macrophage lines with B. pseudolongum induced the antiinflammatory cytokine IL-10 and homeostatic chemokine CCL19 but induced lesser amounts of the proinflammatory cytokines TNFalpha and IL-6. In contrast, LPS and Desulfovibrio desulfuricans (D. desulfuricans), more abundant in colitic FMT, induced a more inflammatory cytokine response. Analysis of mesenteric and peripheral lymph node structure showed that B. pseudolongum gavage resulted in a higher laminin alpha4/alpha5 ratio in the lymph node cortical ridge, indicative of a suppressive environment, while D. desulfuricans resulted in a lower laminin alpha4/alpha5 ratio, supportive of inflammation. Discrete gut bacterial species alter immunity and may predict graft outcomes through stimulation of myeloid cells and shifts in lymph node structure and permissiveness. PMID- 30282819 TI - Ex vivo lung perfusion as a human platform for preclinical small molecule testing. AB - The acute respiratory distress syndrome (ARDS) causes an estimated 70,000 US deaths annually. Multiple pharmacologic interventions for ARDS have been tested and failed. An unmet need is a suitable laboratory human model to predictively assess emerging therapeutics on organ function in ARDS. We previously demonstrated that the small molecule BC1215 blocks actions of a proinflammatory E3 ligase-associated protein, FBXO3, to suppress NF-kappaB signaling in animal models of lung injury. Ex vivo lung perfusion (EVLP) is a clinical technique that maintains lung function for possible transplant after organ donation. We used human lungs unacceptable for transplant to model endotoxemic injury with EVLP for 6 hours. LPS infusion induced inflammatory injury with impaired oxygenation of pulmonary venous circulation. BC1215 treatment after LPS rescued oxygenation and decreased inflammatory cytokines in bronchoalveolar lavage. RNA sequencing transcriptomics from biopsies taken during EVLP revealed robust inflammatory gene induction by LPS with a strong signal for NF-kappaB-associated transcripts. BC1215 treatment reduced the LPS induction of genes associated with inflammatory and host defense gene responses by Gene Ontology (GOterm) and pathways analysis. BC1215 also significantly antagonized LPS-mediated NF-kappaB activity. EVLP may provide a unique human platform for preclinical study of chemical entities such as FBXO3 inhibitors on tissue physiology. PMID- 30282820 TI - Reverse electrical remodeling in rats with heart failure and preserved ejection fraction. AB - Sudden death is the most common mode of exodus in patients with heart failure and preserved ejection fraction (HFpEF). Cardiosphere-derived cells (CDCs) reduce inflammation and fibrosis in a rat model of HFpEF, improving diastolic function and prolonging survival. We tested the hypothesis that CDCs decrease ventricular arrhythmias (VAs) and thereby possibly contribute to prolonged survival. Dahl salt-sensitive rats were fed a high-salt diet to induce HFpEF. Allogeneic rat CDCs (or phosphate-buffered saline as placebo) were injected in rats with echo verified HFpEF. CDC-injected HFpEF rats were less prone to VA induction by programmed electrical stimulation. Action potential duration (APD) was shortened, and APD homogeneity was increased by CDC injection. Transient outward potassium current density was upregulated in cardiomyocytes from CDC rats relative to placebo, as were the underlying transcript (Kcnd3) and protein (Kv4.3) levels. Fibrosis was attenuated in CDC-treated hearts, and survival was increased. Sudden death risk also trended down, albeit nonsignificantly. CDC therapy decreased VA in HFpEF rats by shortening APD, improving APD homogeneity, and decreasing fibrosis. Unlike other stem/progenitor cells, which often exacerbate arrhythmias, CDCs reverse electrical remodeling and suppress arrhythmogenesis in HFpEF. PMID- 30282821 TI - Somatostatin receptor subtype 5 modifies hypothalamic-pituitary-adrenal axis stress function. AB - Pituitary corticotroph somatostatin receptor subtype 5 (SSTR5) signals to inhibit adrenocorticotrophin (ACTH) secretion. As ACTH deficiency results in attenuated adrenal cortisol production and an impaired stress response, we sought to clarify the role of SSTR5 in modifying the hypothalamic/pituitary/adrenal (HPA) axis. We generated Tg HP5 mice overexpressing SSTR5 in pituitary corticotrophs that produce the ACTH precursor proopiomelanocortin (POMC). Basal ACTH and corticosterone were similar in HP5 and WT mice, while HP5 mice showed attenuated ACTH and corticosterone responses to corticotrophin releasing hormone (CRH). HP5 mice exhibited attenuated corticosterone responses upon a restraint stress test and inflammatory stress following LPS injection, as well as increased anxiety like and depressive-like behavior on open field and forced swim tests. Pituitary corticotroph CRH receptor subtype 1 (CRHR1) mRNA expression and ACTH responses to CRH were also attenuated in HP5 mice. In AtT20 cells stably overexpressing SSTR5, CRHR1 expression and cAMP response to CRH were reduced, whereas both were increased after SSTR5 KO. In elucidating mechanisms for these observations, we show that SSTR5-induced miR-449c suppresses both CRHR1 expression and function. We conclude that corticotroph SSTR5 attenuates HPA axis responses via CRHR1 downregulation, suggesting a role for SSTR5 in the pathogenesis of secondary adrenal insufficiency. PMID- 30282822 TI - Colonic epithelial miR-31 associates with the development of Crohn's phenotypes. AB - BACKGROUND: Crohn's disease (CD) is highly heterogeneous, due in large part to variability in cellular processes that underlie the natural history of CD, thereby confounding effective therapy. There is a critical need to advance understanding of the cellular mechanisms that drive CD heterogeneity. METHODS: We performed small RNA sequencing of adult colon tissue from CD and NIBD controls. Colonic epithelial cells and immune cells were isolated from colonic tissues, and microRNA-31 (miR-31) expression was measured. miR-31 expression was measured in colonoid cultures generated from controls and patients with CD. We performed small RNA-sequencing of formalin-fixed paraffin-embedded colon and ileum biopsies from treatment-naive pediatric patients with CD and controls and collected data on disease features and outcomes. RESULTS: Small RNA-sequencing and microRNA profiling in the colon revealed 2 distinct molecular subtypes, each with different clinical associations. Notably, we found that miR-31 expression was a driver of these 2 subtypes and, further, that miR-31 expression was particularly pronounced in epithelial cells. Colonoids revealed that miR-31 expression differences are preserved in this ex vivo system. In adult patients, low colonic miR-31 expression levels at the time of surgery were associated with worse disease outcome as measured by need for an end ileostomy and recurrence of disease in the neoterminal ileum. In pediatric patients, lower miR-31 expression at the time of diagnosis was associated with future development of fibrostenotic ileal CD requiring surgeryCONCLUSIONS. These findings represent an important step forward in designing more effective clinical trials and developing personalized CD therapies.

PMID- 30282824 TI - Clinical implications of monitoring nivolumab immunokinetics in non-small cell lung cancer patients. AB - BACKGROUND: The PD-1-blocking antibody nivolumab persists in patients several weeks after the last infusion. However, no study has systematically evaluated the maximum duration that the antibody persists on T cells or the association between this duration and residual therapeutic efficacy or potential adverse events. METHODS: To define the duration of binding and residual efficacy of nivolumab after discontinuation, we developed a simplified strategy for T cell monitoring and used it to analyze T cells from peripheral blood from 11 non-small cell lung cancer patients previously treated with nivolumab. To determine the suitability of our method for other applications, we compared transcriptome profiles between nivolumab-bound and nivolumab-unbound CD8 T cells. We also applied T cell monitoring in 2 nivolumab-treated patients who developed progressive lung tumors during long-term follow-up. RESULTS: Prolonged nivolumab binding was detected more than 20 weeks after the last infusion, regardless of the total number of nivolumab infusions (2-15 doses) or type of subsequent treatment, in 9 of the 11 cases in which long-term monitoring was possible. Ki-67 positivity, a proliferation marker, in T cells decreased in patients with progressive disease. Transcriptome profiling identified the signals regulating activation of nivolumab bound T cells, which may contribute to nivolumab resistance. In 2 patients who restarted nivolumab, T cell proliferation markers exhibited the opposite trend and correlated with clinical response. CONCLUSIONS: Although only a few samples were analyzed, our strategy of monitoring both nivolumab binding and Ki-67 in T cells might help determine residual efficacy under various types of concurrent or subsequent treatment.

PMID- 30282825 TI - SYK inhibitor entospletinib prevents ocular and skin GVHD in mice. AB - Graft-versus-host disease (GVHD) is a major complication of hematopoietic stem cell transplantation (HCT). The tyrosine kinase SYK contributes to both acute and chronic GVHD development, making it an attractive target for GVHD prevention. Entospletinib (ENTO) is a second-generation highly selective SYK inhibitor with a high safety profile. Potential utility of ENTO as GVHD prophylaxis in patients was examined using a preclinical mouse model of eye and skin GVHD and ENTO compounded chow. We found that early SYK inhibition improved blood immune cell reconstitution in GVHD mice and prolonged survival, with 60% of mice surviving to day +120 compared with 10% of mice treated with placebo. Compared with mice receiving placebo, mice receiving ENTO had dramatic improvements in clinical eye scores, alopecia scores, and skin scores. Infiltrating SYK+ cells expressing B220 or F4/80, resembling SYK+ cells found in lichenoid skin lesions of chronic GVHD patients, were abundant in the skin of placebo mice but were rare in ENTO-treated mice. Thus, ENTO given early after HCT safely prevented GVHD. PMID- 30282823 TI - Arginine vasopressin infusion is sufficient to model clinical features of preeclampsia in mice. AB - Copeptin, a marker of arginine vasopressin (AVP) secretion, is elevated throughout human pregnancies complicated by preeclampsia (PE), and AVP infusion throughout gestation is sufficient to induce the major phenotypes of PE in mice. Thus, we hypothesized a role for AVP in the pathogenesis of PE. AVP infusion into pregnant C57BL/6J mice resulted in hypertension, renal glomerular endotheliosis, intrauterine growth restriction, decreased placental growth factor (PGF), altered placental morphology, placental oxidative stress, and placental gene expression consistent with human PE. Interestingly, these changes occurred despite a lack of placental hypoxia or elevations in placental fms-like tyrosine kinase-1 (FLT1). Coinfusion of AVP receptor antagonists and time-restricted infusion of AVP uncovered a mid-gestational role for the AVPR1A receptor in the observed renal pathologies, versus mid- and late-gestational roles for the AVPR2 receptor in the blood pressure and fetal phenotypes. These findings demonstrate that AVP is sufficient to initiate phenotypes of PE in the absence of placental hypoxia, and indicate that AVP may mechanistically (independently, and possibly synergistically with hypoxia) contribute to the development of clinical signs of PE in specific subtypes of human PE. Additionally, they identify divergent and gestational time-specific signaling mechanisms that mediate the development of PE phenotypes in response to AVP. PMID- 30282826 TI - The DILfrequency study is an adaptive trial to identify optimal IL-2 dosing in patients with type 1 diabetes. AB - BACKGROUND: Type 1 diabetes (T1D) results from loss of immune regulation, leading to the development of autoimmunity to pancreatic beta cells, involving autoreactive T effector cells (Teffs). Tregs, which prevent autoimmunity, require IL-2 for maintenance of immunosuppressive functions. Using a response-adaptive design, we aimed to determine the optimal regimen of aldesleukin (recombinant human IL-2) to physiologically enhance Tregs while limiting expansion of Teffs. METHODS: DILfrequency is a nonrandomized, open-label, response-adaptive study of participants, aged 18-70 years, with T1D. The initial learning phase allocated 12 participants to 6 different predefined regimens. Then, 3 cohorts of 8 participants were sequentially allocated dose frequencies, based on repeated interim analyses of all accumulated trial data. The coprimary endpoints were percentage change in Tregs and Teffs and CD25 (alpha subunit of the IL-2 receptor) expression by Tregs, from baseline to steady state. RESULTS: Thirty eight participants were enrolled, with thirty-six completing treatment. The optimal regimen to maintain a steady-state increase in Tregs of 30% and CD25 expression of 25% without Teff expansion is 0.26 * 106 IU/m2 (95% CI -0.007 to 0.485) every 3 days. Tregs and CD25 were dose-frequency responsive, Teffs were not. The commonest adverse event was injection site reaction (464 of 694 events). CONCLUSIONS: Using a response-adaptive design, aldesleukin treatment can be optimized. Our methodology can generally be employed to immediately access proof of mechanism, thereby leading to more efficient and safe drug development.

PMID- 30282828 TI - Mucosal-associated invariant and gammadelta T cell subsets respond to initial Mycobacterium tuberculosis infection. AB - Innate immune responses that control early Mtb infection are poorly understood, but understanding these responses may inform vaccination and immunotherapy strategies. Innate T cells that respond to conserved bacterial ligands such as mucosal-associated invariant T (MAIT) and gammadelta T cells are prime candidates to mediate these early innate responses but have not been examined in subjects who have been recently exposed to Mtb. We recruited a cohort living in the same household with an active tuberculosis (TB) case and examined the abundance and functional phenotypes of 3 innate T cell populations reactive to M. tuberculosis: gammadelta T, invariant NK T (iNKT), and MAIT cells. Both MAIT and gammadelta T cells from subjects with Mtb exposure display ex vivo phenotypes consistent with recent activation. However, both MAIT and gammadelta T cell subsets have distinct response profiles, with CD4+ MAIT and gammadelta T cells accumulating after infection. Examination of exposed but uninfected contacts demonstrates that resistance to initial infection is accompanied by robust MAIT cell CD25 expression and granzyme B production coupled with a depressed CD69 and IFNgamma response. Finally, we demonstrate that MAIT cell abundance and function correlate with the abundance of specific gut microbes, suggesting that responses to initial infection may be modulated by the intestinal microbiome. PMID- 30282829 TI - Dual TLR2 and TLR7 agonists as HIV latency-reversing agents. AB - The presence of a reservoir of latently infected cells in HIV-infected patients is a major barrier towards finding a cure. One active cure strategy is to find latency-reversing agents that induce viral reactivation, thus leading to immune cell recognition and elimination of latently infected cells, known as the shock and-kill strategy. Therefore, the identification of molecules that reactivate latent HIV and increase immune activation has the potential to further these strategies into the clinic. Here, we characterized synthetic molecules composed of a TLR2 and a TLR7 agonist (dual TLR2/7 agonists) as latency-reversing agents and compared their activity with that of the TLR2 agonist Pam2CSK4 and the TLR7 agonist GS-9620. We found that these dual TLR2/7 agonists reactivate latency by 2 complementary mechanisms. The TLR2 component reactivates HIV by inducing NF kappaB activation in memory CD4+ T cells, while the TLR7 component induces the secretion of TNF-alpha by monocytes and plasmacytoid dendritic cells, promoting viral reactivation in CD4+ T cells. Furthermore, the TLR2 component induces the secretion of IL-22, which promotes an antiviral state and blocks HIV infection in CD4+ T cells. Our study provides insight into the use of these agonists as a multipronged approach targeting eradication of latent HIV. PMID- 30282830 TI - Myeloid HO-1 modulates macrophage polarization and protects against ischemia reperfusion injury. AB - Macrophages polarize into heterogeneous proinflammatory M1 and antiinflammatory M2 subtypes. Heme oxygenase 1 (HO-1) protects against inflammatory processes such as ischemia-reperfusion injury (IRI), organ transplantation, and atherosclerosis. To test our hypothesis that HO-1 regulates macrophage polarization and protects against IRI, we generated myeloid-specific HO-1-knockout (mHO-1-KO) and transgenic (mHO-1-Tg) mice, with deletion or overexpression of HO-1, in various macrophage populations. Bone marrow-derived macrophages (BMDMs) from mHO-1-KO mice, treated with M1-inducing LPS or M2-inducing IL-4, exhibited increased mRNA expression of M1 (CXCL10, IL-1beta, MCP1) and decreased expression of M2 (Arg1 and CD163) markers as compared with controls, while BMDMs from mHO-1-Tg mice displayed the opposite. A similar pattern was observed in the hepatic M1/M2 expression profile in a mouse model of liver IRI. mHO-1-KO mice displayed increased hepatocellular damage, serum AST/ALT levels, Suzuki's histological score of liver IRI, and neutrophil and macrophage infiltration, while mHO-1-Tg mice exhibited the opposite. In human liver transplant biopsies, subjects with higher HO-1 levels showed lower expression of M1 markers together with decreased hepatocellular damage and improved outcomes. In conclusion, myeloid HO-1 expression modulates macrophage polarization, and protects against liver IRI, at least in part by favoring an M2 phenotype. PMID- 30282827 TI - Fat fibrosis: friend or foe? AB - At the simplest level, obesity is the manifestation of an imbalance between caloric intake and expenditure; however, the pathophysiological mechanisms that govern the development of obesity and associated complications are enormously complex. Fibrosis within the adipose tissue compartment is one such factor that may influence the development of obesity and/or obesity-related comorbidities. Furthermore, the functional consequences of adipose tissue fibrosis are a matter of considerable debate, with evidence that fibrosis serves both adaptive and maladaptive roles. Tissue fibrosis itself is incompletely understood, and multiple cellular and molecular pathways are involved in the development, maintenance, and resolution of the fibrotic state. Within the context of obesity, fibrosis influences molecular and cellular events that relate to adipocytes, inflammatory cells, inflammatory mediators, and supporting adipose stromal tissue. In this Review, we explore what is known about the interplay between the development of adipose tissue fibrosis and obesity, with a view toward future investigative and therapeutic avenues. PMID- 30282831 TI - A sheep model of cystic fibrosis generated by CRISPR/Cas9 disruption of the CFTR gene. AB - Cystic fibrosis (CF) is a genetic disease caused by mutations in the CF transmembrane conductance regulator (CFTR) gene. The major cause of limited life span in CF patients is progressive lung disease. CF models have been generated in 4 species (mice, rats, ferrets, and pigs) to enhance our understanding of the CF pathogenesis. Sheep may be a particularly relevant animal to model CF in humans due to the similarities in lung anatomy and development in the two species. Here, we describe the generation of a sheep model for CF using CRISPR/Cas9 genome editing and somatic cell nuclear transfer (SCNT) techniques. We generated cells with CFTR gene disruption and used them for production of CFTR-/- and CFTR+/- lambs. The newborn CFTR-/- sheep developed severe disease consistent with CF pathology in humans. Of particular relevance were pancreatic fibrosis, intestinal obstruction, and absence of the vas deferens. Also, substantial liver and gallbladder disease may reflect CF liver disease that is evident in humans. The phenotype of CFTR-/- sheep suggests this large animal model will be a useful resource to advance the development of new CF therapeutics. Moreover, the generation of specific human CF disease-associated mutations in sheep may advance personalized medicine for this common genetic disorder. PMID- 30282832 TI - Chronic linaclotide treatment reduces colitis-induced neuroplasticity and reverses persistent bladder dysfunction. AB - Irritable bowel syndrome (IBS) patients suffer from chronic abdominal pain and extraintestinal comorbidities, including overactive bladder (OAB) and interstitial cystitis/painful bladder syndrome (IC-PBS). Mechanistic understanding of the cause and time course of these comorbid symptoms is lacking, as are clinical treatments. Here, we report that colitis triggers hypersensitivity of colonic afferents, neuroplasticity of spinal cord circuits, and chronic abdominal pain, which persists after inflammation. Subsequently, and in the absence of bladder pathology, colonic hypersensitivity induces persistent hypersensitivity of bladder afferent pathways, resulting in bladder-voiding dysfunction, indicative of OAB/IC-PBS. Daily administration of linaclotide, a guanylate cyclase-C (GC-C) agonist that is restricted to and acts within the gastrointestinal tract, reverses colonic afferent hypersensitivity, reverses neuroplasticity-induced alterations in spinal circuitry, and alleviates chronic abdominal pain in mice. Intriguingly, daily linaclotide administration also reverses persistent bladder afferent hypersensitivity to mechanical and chemical stimuli and restores normal bladder voiding. Linaclotide itself does not inhibit bladder afferents, rather normalization of bladder function by daily linaclotide treatment occurs via indirect inhibition of bladder afferents via reduced nociceptive signaling from the colon. These data support the concepts that cross organ sensitization underlies the development and maintenance of visceral comorbidities, while pharmaceutical treatments that inhibit colonic afferents may also improve urological symptoms through common sensory pathways. PMID- 30282834 TI - Thrombocytopenia is associated with severe retinopathy of prematurity. AB - Retinopathy of prematurity (ROP) is characterized by abnormal retinal neovascularization in response to vessel loss. Platelets regulate angiogenesis and may influence ROP progression. In preterm infants, we assessed ROP and correlated with longitudinal postnatal platelet counts (n = 202). Any episode of thrombocytopenia (<100 * 109/l) at >=30 weeks postmenstrual age (at onset of ROP) was independently associated with severe ROP, requiring treatment. Infants with severe ROP also had a lower weekly median platelet count compared with infants with less severe ROP. In a mouse oxygen-induced retinopathy model of ROP, platelet counts were lower at P17 (peak neovascularization) versus controls. Platelet transfusions at P15 and P16 suppressed neovascularization, and platelet depletion increased neovascularization. Platelet transfusion decreased retinal of vascular endothelial growth factor A (VEGFA) mRNA and protein expression; platelet depletion increased retinal VEGFA mRNA and protein expression. Resting platelets with intact granules reduced neovascularization, while thrombin activated degranulated platelets did not. These data suggest that platelet releasate has a local antiangiogenic effect on endothelial cells to exert a downstream suppression of VEGFA in neural retina. Low platelet counts during the neovascularization phase in ROP is significantly associated with the development of severe ROP in preterm infants. In a murine model of retinopathy, platelet transfusion during the period of neovascularization suppressed retinopathy. PMID- 30282835 TI - Treatment of Streptococcus pneumoniae otitis media in a chinchilla model by transtympanic delivery of antibiotics. AB - Otits media (OM) is the most frequent indication for antimicrobial prescription to US children. Streptococcus pneumoniae (S. pneumoniae) remains one of the most common pathogens causing OM. Successful eradication of S. pneumoniae in the middle ear can be achieved by adhering to a 7-10 day regimen of oral antibiotics. However, oral drug administration is challenging for parents. Lack of adherence has been associated with treatment failure or early relapse. To overcome this challenge, we used a noninvasive formulation to achieve high transtympanic antibiotic flux and cured S. pneumoniae OM in chinchillas. The formulation consists of a thermosensitive in situ gelling hydrogel, chemical permeation enhancers, and an antibiotic. The direct transport of drugs into the middle ear produced high concentrations of ciprofloxacin (in the range of hundreds of micrograms per milliliter) within the first 24 hours of administration. Drug concentrations above the minimum inhibitory concentration (MIC) for S. pneumoniae were sustained throughout the 7-day treatment. S. pneumoniae OM in a chinchilla model was successfully eradicated, without causing tissue toxicity. Transtympanic delivery minimized systemic drug exposure, as evidenced by undetectable levels in blood, measured by high-performance liquid chromatography. PMID- 30282833 TI - Splicing modulation sensitizes chronic lymphocytic leukemia cells to venetoclax by remodeling mitochondrial apoptotic dependencies. AB - The identification of targetable vulnerabilities in the context of therapeutic resistance is a key challenge in cancer treatment. We detected pervasive aberrant splicing as a characteristic feature of chronic lymphocytic leukemia (CLL), irrespective of splicing factor mutation status, which was associated with sensitivity to the spliceosome modulator, E7107. Splicing modulation affected CLL survival pathways, including members of the B cell lymphoma-2 (BCL2) family of proteins, remodeling antiapoptotic dependencies of human and murine CLL cells. E7107 treatment decreased myeloid cell leukemia-1 (MCL1) dependence and increased BCL2 dependence, sensitizing primary human CLL cells and venetoclax-resistant CLL like cells from an EMU-TCL1-based adoptive transfer murine model to treatment with the BCL2 inhibitor venetoclax. Our data provide preclinical rationale to support the combination of venetoclax with splicing modulators to reprogram apoptotic dependencies in CLL for treating venetoclax-resistant CLL cases. PMID- 30282838 TI - Loss of ACAT1 Attenuates Atherosclerosis Aggravated by Loss of NCEH1 in Bone Marrow-Derived Cells. AB - AIM: Acyl-CoA cholesterol acyltransferase 1 (ACAT1) esterifies free cholesterol to cholesteryl esters (CE), which are subsequently hydrolyzed by neutral cholesterol ester hydrolase 1 (NCEH1). The elimination of ACAT1 in vitro reduces the amounts of CE accumulated in Nceh1-deficient macrophages. The present study aimed at examining whether the loss of ACAT1 attenuates atherosclerosis which is aggravated by the loss of NCEH1 in vivo. METHODS: Low density lipoprotein receptor (Ldlr)-deficient mice were transplanted with bone marrow from wild-type mice and mice lacking ACAT1, NCEH1, or both. The four types of mice were fed a high-cholesterol diet and, then, were examined for atherosclerosis. RESULTS: The cross-sectional lesion size of the recipients of Nceh1-deficient bone marrow was 1.6-fold larger than that of the wild-type bone marrow. The lesions of the recipients of Nceh1-deficient bone marrow were enriched with MOMA2-positive macrophages compared with the lesions of the recipients of the wild-type bone marrow. The size and the macrophage content of the lesions of the recipients of bone marrow lacking both ACAT1 and NCEH1 were significantly smaller than the recipients of the Nceh1-deficient bone marrow, indicating that the loss of ACAT1 decreases the excess CE in the Nceh1-deficient lesions. The collagen-rich and/or mucin-rich areas and en face lesion size were enlarged in the recipients of the Acat1-/- bone marrow compared with those of the recipients of the WT bone marrow. CONCLUSION: The loss of ACAT1 in bone marrow-derived cells attenuates atherosclerosis, which is aggravated by the loss of NCEH1, corroborating the in vitro functions of ACAT1 (formation of CE) and NCEH1 (hydrolysis of CE). PMID- 30282836 TI - High-throughput T cell receptor sequencing identifies clonally expanded CD8+ T cell populations in alopecia areata. AB - Alopecia areata (AA) is an autoimmune disease in which cytotoxic T cells specifically target growing hair follicles. We used high-throughput TCR sequencing in the C3H/HeJ mouse model of AA and in human AA patients to gain insight into pathogenic T cell populations and their dynamics, which revealed clonal CD8+ T cell expansions in lesional skin. In the C3H/HeJ model, we observed interindividual sharing of TCRbeta chain protein sequences, which strongly supports a model of antigenic drive in AA. The overlap between the lesional TCR repertoire and a population of CD8+NKG2D+ T cells in skin-draining lymph nodes identified this subset as pathogenic effectors. In AA patients, treatment with the oral JAK inhibitor tofacitinib resulted in a decrease in clonally expanded CD8+ T cells in the scalp but also revealed that many expanded lesional T cell clones do not completely disappear from either skin or blood during treatment with tofacitinib, which may explain in part the relapse of disease after stopping treatment. PMID- 30282839 TI - Palladium-Catalyzed C-H Heteroarylation of 2,5-Disubstituted Imidazoles. AB - We developed a palladium-catalyzed C-H N-heteroarylation of N-protected-2,5 disubstituted imidazoles at the C4-position using N-heteroaryl halides as a coupling partner. Intensive reaction condition screening led us to identify fluorinated bathophenanthroline 7 as the optimum ligand for the palladium catalyst. This reaction will enhance lead optimization of drug candidates by facilitating the synthesis of heterobiaryl compounds containing an imidazole ring. PMID- 30282837 TI - Enhanced detection of neoantigen-reactive T cells targeting unique and shared oncogenes for personalized cancer immunotherapy. AB - Adoptive cell transfer (ACT) of tumor-infiltrating lymphocytes (TILs) targeting neoantigens can mediate tumor regression in selected patients with metastatic epithelial cancer. However, effectively identifying and harnessing neoantigen reactive T cells for patient treatment remains a challenge and it is unknown whether current methods to detect neoantigen-reactive T cells are missing potentially clinically relevant neoantigen reactivities. We thus investigated whether the detection of neoantigen-reactive TILs could be enhanced by enriching T cells that express PD-1 and/or T cell activation markers followed by microwell culturing to avoid overgrowth of nonreactive T cells. In 6 patients with metastatic epithelial cancer, this method led to the detection of CD4+ and CD8+ T cells targeting 18 and 1 neoantigens, respectively, compared with 6 and 2 neoantigens recognized by CD4+ and CD8+ T cells, respectively, when using our standard TIL fragment screening approach. In 2 patients, no recognition of mutated peptides was observed using our conventional screen, while our high throughput approach led to the identification of 5 neoantigen-reactive T cell receptors (TCRs) against 5 different mutations from one patient and a highly potent MHC class II-restricted KRASG12V-reactive TCR from a second patient. In addition, in a metastatic tumor sample from a patient with serous ovarian cancer, we isolated 3 MHC class II-restricted TCRs targeting the TP53G245S hot-spot mutation. In conclusion, this approach provides a highly sensitive platform to isolate clinically relevant neoantigen-reactive T cells or their TCRs for cancer treatment. PMID- 30282840 TI - Latent bovine herpesvirus 1 and 5 in milk from naturally infected dairy cattle. AB - Bovine herpesvirus 1 and 5 (BoHV-1 and -5) are antigenically and genetically related and can establish latent infection. We aimed to analyze the applicability of the milk sample to detect latently BoHV-infected cattle. BoHV-1 non-vaccinated clinically healthy cows from five dairy cattle herds (herd 1, n=24; herd 2, n=39; herd 3, n=39; herd 4, n=36; herd 5, n=70) were studied. We confirmed the presence of BoHV-1, and for the first time, BoHV-5 in the milk of naturally infected dairy cattle. PMID- 30282841 TI - Detection of neutralizing antibody against porcine epidemic diarrhea virus in subclinically infected finishing pigs. AB - The purpose of this study was to detect porcine epidemic diarrhea virus (PEDV) subclinically infected pigs shipped from non-case farms to slaughterhouses. Systematic sampling was conducted at two slaughterhouses. A total of 1,556 blood samples were collected from 80 case and non-case farms from pigs over 6 months old. Blood samples were centrifuged to obtain sera. Serial serum dilutions were subjected to serological examination for PEDV presence using Neutralization test (NT). The cut-off titer was set at titer of 1:2 dilution and farms with at least one positive sample in duplicate were classified as PED-positive farms. Several non-case farms (9.4%, 6/64) and 100% (16/16) of the case farms were indeed positive for PEDV. The proportion of seropositive animals from case farms was 63.7%, significantly different from that of non-case farms (4.3%, P<0.05). In both case and non-case farms, the proportion of seropositive animals in farrow-to finish farms was significantly higher than in wean-to-finish farms (P<0.05). Seropositive animals in non-case farms were detected by NT in a sero-survey by sampling at slaughterhouses. Therefore, subclinically infected pigs should be considered prior to shipment. PMID- 30282843 TI - Measurement of visual acuity in Beagle dog by visual evoked potential with pattern stimulation. AB - We tried measurement of visual acuity in laboratory beagle using pattern stimulus visual evoked potential (P-VEP). We recorded P-VEP in 6 beagles which were corrected refractive power. The stimulus pattern size was 1.22 mm. The testing distance were 0.5, 1.0, and 2.0 m. The visual angles and spatial frequency were calculated from stimulus pattern size and distance. In all subjects, P-VEP was clearly recorded in all testing distance, and this result means that the eye could recognized grid pattern on the stimulus monitor. When stimulus monitor was set up 2.0 m, spatial frequency was 14.29 cpd. From our results, it was founded that the visual acuity in laboratory beagle which was corrected refractive power was 14.29 cpd and more. PMID- 30282842 TI - Glycerol induces early fibrosis in regenerating rat skeletal muscle. AB - Glycerol has been recently used to induce muscle adiposity in mice. However, its effects on the rat muscles have not been investigated previously. Therefore, we investigated the regeneration outcomes of rat muscles following glycerol-induced injury at different time points. Glycerol injection induced myofiber degeneration with extensive inflammatory infiltration on day 4 followed by appearance of regenerating myotubes on day 7 after injury without adipocyte infiltration. Meanwhile, a significant collagen deposition at early stage of regeneration that increased together with persistent inflammatory infiltration up to day 14 after injury indicates impaired regeneration. In conclusion, glycerol injury in rats is more suitable as a fibrosis-inducing model than in mice due to earlier and higher accumulation of fibrous tissue with lacking adipogenesis. PMID- 30282844 TI - Sleep Disturbance and Hyperactivity Detected by Actigraphy in Rats with Allergic Rhinitis or Attention-Deficit Hyperactivity Disorder. AB - Actigraphy is an easy and noninvasive method used to monitor human ultradian cycles. However, to our knowledge, it has been not applied to experiments with rodents. Therefore, using actigraphy, we assessed the ultradian cycles and behavior of rats. Rats with or without allergic rhinitis wore an actigraphy device, and triaxial acceleration was recorded. The counts that represent physical activity were lower from 8:00 to 20:00 than those from 20:00 to 8:00 in control rats, suggesting that their sleep phase was from 8:00 to 20:00 and their awake phase from 20:00 to 8:00. The counts from 8:00 to 10:00 were significantly higher in allergic rhinitis rats than in control rats (p < 0.01), suggesting the presence of difficulty with sleep induction in rats with allergic rhinitis. The counts from 18:00 to 20:00 were also significantly higher in allergic rhinitis rats than in control rats (p < 0.05), suggesting the presence of early awakening in rats with allergic rhinitis. Moreover, the counts were significantly higher in allergic rhinitis rats than in control rats from 20:00 to 8:00. These results suggest that rats with allergic rhinitis experienced hyperactivity disorder during the daytime. Additionally, hyperreactivity and difficulty with sleep induction were observed in 6-hydroxydopamine-lesioned rats, an animal model of attention-deficit hyperactivity disorder. This study shows for the first time that actigraphy can be successfully used for behavioral analysis in rodents. These rat models could be useful for analyzing the mechanisms involved in sleep disturbances and hyperactivity disorder. PMID- 30282845 TI - Vaccination Status and Antibody Titers against Rubella and Measles among Japanese Female College Students Majoring in Childcare between 2015 and 2018. AB - In 2014, for the protection of medical workers against measles and rubella infection, the Japanese Society for Infection Prevention and Control (JSIPC) recommended either maintaining antibody titers of seroprotective range or two dose vaccination. JSIPC defined antibody titers into 3 ranges: seroprotective as expected prevention of infection, seronegative as under detection levels, and seropositive as antibody titers ranged between seronegative and seroprotective. This study aimed to explore the association between the number of vaccine doses received and the antibody titers against measles and rubella among Japanese college students majoring in childcare. A total of 841 female students with no history of measles or rubella were serologically screened at the time of college admission between 2015 and 2018. All 841 students had been vaccinated against measles; 738 (87.8%) received two doses of the measles vaccine and 103 (12.2%) received one dose. Likewise, 839 students, except for two, had been vaccinated against rubella; 719 (85.7%) received two doses of the rubella vaccine and 120 (14.3%) received one dose. We thus found that 107 students (12.7%) were seropositive for measles-specific IgG and 731 (86.9%) attained seroprotective titers. By contrast, in case of rubella-specific IgG, only 462 students (55.1%) attained seroprotective titers, and 371 students (44.1%) were seropositive. The two students without receiving rubella vaccination were classified as seronegative. In conclusion, despite that > 85% of students surveyed had received two doses of measles and rubella vaccines, a substantial number of students remain susceptible to measles and especially rubella at the time of college admission. PMID- 30282846 TI - Food aversion learning based on voluntary running in non-deprived rats: a technique for establishing aversive conditioning with minimized discomfort. AB - This article presents an experimental preparation for establishing conditioned food aversion (CFA) by voluntary wheel running in rats with laboratory chow and water freely available. In Experiment 1, unfamiliar food (raisins) was avoided by rats when they first encountered it. This neophobic food avoidance was habituated by repeated tests; the rats gradually increased their raisin consumption. However, the consumption remained suppressed in rats that accessed the raisins after wheel running. This finding implies that running yielded CFA, which suppressed consumption of the unfamiliar food rather than increasing it. Because running generated kaolin clay ingestion, which is a behavioral marker of nausea, it is suggested that the running-based CFA was mediated by weak gastrointestinal discomfort. Experiment 2 supported the claim that the suppressed consumption is due to running-based CFA by showing the specificity of food suppression. Demonstration of CFA based on voluntary activity in non-deprived rats will contribute to basic research on learning and memory as an alternative technique for studying aversive conditioning with minimized discomfort in animals. PMID- 30282847 TI - Emerging Role of Plasma Membranes in Vascular Endothelial Mechanosensing. AB - Vascular endothelial cells (ECs) maintain circulatory system homeostasis by changing their functions in response to changes in hemodynamic forces, including shear stress and stretching. However, it is unclear how ECs sense changes in shear stress and stretching and transduce these changes into intracellular biochemical signals. The plasma membranes of ECs have recently been shown to respond to shear stress and stretching differently by rapidly changing their lipid order, fluidity, and cholesterol content. Such changes in the membranes' physical properties trigger the activation of membrane receptors and cell responses specific to each type of force. Artificial lipid-bilayer membranes show similar changes in lipid order in response to shear stress and stretching, indicating that they are physical phenomena rather than biological reactions. These findings suggest that the plasma membranes of ECs act as mechanosensors; in response to mechanical forces, they first alter their physical properties, modifying the conformation and function of membrane proteins, which then activates downstream signaling pathways. This new appreciation of plasma membranes as mechanosensors could help to explain the distinctive features of mechanotransduction in ECs involving shear stress and stretching, which activate a variety of membrane proteins and multiple signal transduction pathways almost simultaneously. PMID- 30282848 TI - Validation of Conventional Thromboembolic Risk Factors in a Korean Atrial Fibrillation Population - Suggestion for a Novel Scoring System, CHA2DS2-VAK. AB - BACKGROUND: There is little evidence that focuses on the ethnic variability of clinical risk factors for thromboembolism (TE) in atrial fibrillation (AF). We aimed to investigate the effect of each traditional risk factor in the Korean AF population. Methods and Results: Medical records of 12,876 consecutive patients (aged >18 years) newly diagnosed and followed up with non-valvular AF from 2000 to 2013 were reviewed. TE events, including ischemic stroke and systemic embolism, were investigated for risk factor validation. Among the total of 12,876 patients, 1,390 (10.8%) had TE events. In univariate/multivariate analysis adjusting for clinical factors and antithrombotic medications, traditional risk factors included in the CHA2DS2-VASc scheme showed statistical significance, except for female sex, which was not a predictor of events. Additionally, chronic kidney disease (CKD; hazard ratio 1.62, P<0.001) was shown to be an independent predictor of TE events. Based on the analysis, we developed a novel stratification system, CHA2DS2-VAK, omitting the female sex category and adding CKD. The new scoring system showed greater discrimination in event rates between score 0 and 1 patients. CONCLUSIONS: Female sex was not associated with TE events in a Korean non-valvular AF population. The novel CHA2DS2-VAK scoring system, with substitution of CKD for female sex, might be more appropriate for the Korean population. PMID- 30282849 TI - Austin Flint Murmur. PMID- 30282850 TI - Metabolic Profiling of the Hippocampus of Rats Experiencing Nicotine-Withdrawal Symptoms. AB - Nicotine-withdrawal symptoms have been indicated as a possible risk factor for neuropsychiatric events, such as depression and suicide, during use of smoking cessation drugs. We aimed to investigate whether the results of the metabolomic analysis of the rat brain reflect nicotine-withdrawal symptoms. We also aimed to investigate the relative changes in each metabolite in the brains of rats with nicotine-withdrawal symptoms. We created rats experiencing nicotine-withdrawal symptoms through repeat administration of nicotine followed by a 12-h withdrawal period, and rats recovered from nicotine-withdrawal symptoms followed by an 18-h withdrawal period. We then implemented brain metabolic profiling by combining high-resolution magic-angle spinning 1H-NMR spectroscopy with partial least square discriminant analysis (PLS-DA). We found that metabolic profiling of the brain reflects the state during nicotine-withdrawal symptoms and the state after recovery from nicotine-withdrawal symptoms. Additionally, N-acetylaspartate and glutamate increased and aspartate, gamma-aminobutyric acid (GABA), and creatine decreased in the hippocampus of rats experiencing nicotine-withdrawal symptoms. Therefore, it is suggested that neurogenesis and neuronal differentiation could be changed and abnormal energy metabolism could occur in the hippocampus during nicotine-withdrawal symptoms. PMID- 30282851 TI - Evaluation of Tumor Tissue Fixation Effects of Formulation Modified Mohs Pastes in Mice and Their Water-Absorbing Properties. AB - Mohs paste (MP) is a hospital preparation containing zinc hydrochloride and zinc oxide starch. It is a topical medication used to fixate tissues for the removal of inoperable skin tumors and the management of hemorrhage and exudates, and to prevent foul odor resulting from secondary infections. However, it has problems, such as changes in hardness and viscoelasticity with time and liquefaction by exudate. It has been reported that the modified MP with D-sorbitol (S-MP) and the modified MP using the cellulose instead of starch (C-MP) have excellent physicochemical stability and better handling than original MP (O-MP). In this study, the effect of prescription improvement of MP on the pharmacological effect was examined with reference to water absorbing property, and its tumor tissue invasion fixation depth as an indicator. In the S-MP and C-MP, the amounts of water absorption did not differ significantly from those in the O-MP. The hardness of S-MP was decreased and liquefied like O-MP after absorbing water. In contrast, C-MP retained its form even after water absorption. The subcutaneous tumors in mice treated with modified MP formulations were measured for invasion fixation depth at 6 and 24 h after application. And the tissue status was observed using computed tomography. In all MPs, invasion fixation depth increased depending on application time. S-MP and O-MP depths did not differ significantly. The invasion depths of the C-MP significantly increased compared with those in the O-MP. These results suggest that C-MP had a high tissue fixation rate. PMID- 30282852 TI - Skin Sensitization to Fluorescein Isothiocyanate Is Enhanced by Butyl Paraben in a Mouse Model. AB - Contact hypersensitivity (CHS) to preservatives is receiving increased attention. Parabens are widely used in foods, pharmaceutics and cosmetics as preservatives. The skin sensitizing activity of parabens remains controversial but a few investigations have been made as to whether parabens could facilitate sensitization to other chemicals. We have shown that di-n-butyl phthalate (DBP), a phthalate ester, has an adjuvant effect in a fluorescein isothiocyanate (FITC) induced CHS mouse model. We have also demonstrated that DBP activates transient receptor potential ankyrin 1 (TRPA1) cation channels expressed on sensory neurons. Comparative studies of phthalate esters revealed that TRPA1 agonistic activity and the adjuvant effect on FITC-CHS coincide. Here we focused on two commonly used parabens, butyl paraben (BP) and ethyl paraben (EP), as to their adjuvant effects. BALB/c mice were epicutneously sensitized with FITC in acetone in the presence or absence of a paraben. Sensitization to FITC was evaluated as the ear-swelling response after FITC challenge. BP but not EP enhanced skin sensitization to FITC, but the effect of BP was much weaker than that of DBP. Mechanistically, BP enhanced the trafficking of FITC-presenting CD11c+ dendritic cells (DCs) from the skin to draining lymph nodes as well as cytokine production by draining lymph nodes. When the TRPA1 agonistic activity was measured with a cell line expressing TRPA1, BP exhibited higher activity than EP. The present study provides direct in vivo evidence that BP causes sensitization to other chemicals by means of a mouse FITC-CHS model. PMID- 30282853 TI - Recent decreasing trends of exposure to PCDDs/PCDFs/dioxin-like PCBs in general populations, and associations with diabetes, metabolic syndrome, and gout/hyperuricemia. AB - The author reviewed recent reports about the blood levels and dietary intake of polychlorinated dibenzo-p-dioxins (PCDDs)/furans (PCDFs)/dioxin-like polychlorinated biphenyls (DL-PCBs) to investigate the trends of dioxin exposure, and epidemiologic studies on the associations of blood levels of dioxins with metabolic diseases. In recent years, dietary intake of dioxins has been decreasing, and the means are equal to or less than 1.0 pg Toxic Equivalents (TEQ)/kg/day in the general populations of several countries. The blood levels of dioxins are also decreasing, probably because of reduced dietary intake. Many cross-sectional studies reported positive associations between blood levels of some isomers or TEQ-based concentrations of PCDDs/PCDFs/DL-PCBs and diabetes in general populations. Three cohort studies on populations with heavy exposure and two nested case-control studies on general populations have also been published, but the results are inconsistent. Three large-scale cross-sectional studies and two cohort studies reported an association between blood levels of some isomers or TEQ-based concentrations of PCDDs/PCDFs/DL-PCBs and metabolic syndrome. In addition, three cross-sectional studies reported significant positive associations with gout/hyperuricemia. Further prospective studies and experimental studies are needed to establish cause-effect relationships, and to clarify the biological mechanisms for the association between background exposure to dioxins and potential health effects.

PMID- 30282854 TI - Understanding metabolic conversions and molecular actions of flavonoids in vivo:toward new strategies for effective utilization of natural polyphenols in human health. AB - Many papers have suggested the health-beneficial activity of natural dietary polyphenols to prevent chronic diseases and aging processes in humans. It is generally recognized that polyphenols are absorbed from the intestines and metabolized into the phase-II conjugates, i.e., the glucuronides and sulfates. For example, a major dietary flavonoid, quercetin, abundant in onion and buckwheat, is metabolized after oral intake into its conjugates, such as quercetin-3-O-glucuronide and quercetin-3'-O-sulfate, whereas no aglycone was found in the human plasma. Therefore, to understand the mechanisms of the biological activity of quercetin in vivo, we should focus on the molecular actions of these conjugates. In the last decade, we have demonstrated the unique actions of quercetin-3-O-glucuronide at sites of inflammation, including specific accumulation in macrophages and the following deconjugation into active aglycone, catalyzed by the macrophage-derived beta-glucuronidase. This review summarizes recent findings regarding the anti-inflammatory mechanisms of quercetin conjugates in macrophages and propose a possible strategy for the effective utilization of natural polyphenols in our daily diet for prevention of age related chronic diseases.

AB - Tofacitinib is the first Janus Kinase (JAK) inhibitor to treat moderately to severely active RA. In this study, we investigated whether the effect of tofacitinib have any effects on body composition in mice and female patients with RA. Female C57BL/6 mice fed with a high-fat diet were treated with 30 mg/kg/day tofacitinib or vehicle for 70 days. Following treatment, trunk muscle, subcutaneous fat, and visceral fats were measured using X-ray computed tomography CT scan. Glucose tolerance and insulin sensitivity were assessed. In female RA patients treated with biological disease modified anti-rheumatic-drugs (biological DMARDs) or tofacitinib (n=4 per group), we also evaluated the body composition after 3 months from the start of treatment initiation using bioelectrical impedance analysis. Treatment with tofacitinib did not affect the body weight, and body composition in C57BL/6 mice. It also did not affect glucose, and insulin tolerance in mice. In patients with RA, treatment with biological DMARDs did not affect the body composition whereas the muscle mass was unchanged after receiving tofacitinib and the fat mass was significantly increased.

AB - The number of plant factories in which crops are cultivated in an artificial environment has been increasing every year. In cultivation techniques involving hydroponics, plants are supplied with a circulating nutrient solution, which can become contaminated by pathogens that can propagate and spread throughout plant factories. Therefore, strategies to disinfect hydroponic nutrient solutions are needed. In this study, we developed a new disinfection device equipped with an ultraviolet A (UVA) light emitting diode (LED) that can be used to disinfect hydroponic nutrient solutions in plant factories. We first evaluated the basic disinfection capability of the device and then estimated its bactericidal effect in a small scale model system. The log survival ratio was related to UVA irradiation fluence and the volume of nutrient solution. From the assay results, we devised a kinetics equation to describe the relationship between nutrient solution volume, log survival ratio, and UVA fluence. Together our results show that UVA irradiation could be used to disinfect hydroponic nutrient solutions, and the derived kinetics equations can be used to determine optimal conditions, such as nutrient solution volume, UVA irradiation, and killing activity, to develop devices that disinfect hydroponic nutrient solutions.

AB - The purpose of this study was to evaluate the physical features of pediatric patients with lumbar spondylolysis (LS), factors that increase the load during compensatory movements at the lumbar spine, and the outcomes of rehabilitation. Twenty patients were included. Fifteen items were used:fingertip-to-floor distance (FFD), straight leg raising (SLR), heel-to-buttock distance (HBD), tightness of the rectus femoris, the lateral and medial rotator muscles, iliopsoas, tensor fascia lata, adductor muscles, soleus muscle, and latissimus dorsi, and trunk rotation, sit-ups and endurance of the abdominal and back muscles. Initial findings were judged as positive or negative using previously reported cut-off values and were re-evaluated 2 or 3 months later. Positive tests were found for HBD and tightness of the rectus femoris in 85% of the patients, for endurance of the abdominal muscles in 75%, SLR and sit-ups in 70%, and FFD and tightness of the external rotator muscles in 60%. The physical features varied according to the type of sport played, and some patients were refractory to rehabilitation. Only 17.6%, 33.3%, and 40.0% of patients with initially positive findings for HBD, tightness of the external rotator muscles, and endurance of the abdominal muscles, respectively, achieved improvements after rehabilitation.

PMID- 30282858 TI - Impact of the use of Kampo medicine in patients with esophageal cancer during chemotherapy:a clinical trial for oral hygiene and oral condition. AB - OBJECTIVE: The aim of this study was to investigate the impact of the use of two Kampo medicines on oral mucositis, tongue coating bacteria, and gingiva condition in patients with esophageal cancer undergoing chemotherapy. METHODS: Twenty-three esophageal cancer patients who receive chemotherapy at Tokushima University Hospital, were included. The participants, who received professional oral healthcare, were randomly divided into three groups:7 subjects received Daiokanzoto sherbets, 7 subjects received Hangeshashinto sherbets, and 9 subjects received nothing (control). The numbers of total bacteria and specific periodontopathogenic bacteria in tongue coating were determined in addition to clinical parameters. RESULTS: No difference on the onset of oral mucositis was found among the three groups. However, tongue coating index, gingival index (GI), plaque index, the number of total bacteria, Fusobacterium nucleatum and Campylobacter rectus were decreased during chemotherapy. More specifically, GI as well as the number of F. nucleatum and C. rectus were decreased significantly in the Daiokanzoto group when compared to the control group (psize 8 < 0.05). No such differences were observed for the group receiving Hangeshashinto. CONCLUSION: This clinical trial showed that Daiokanzoto might be effective in attenuating gingival inflammation and reducing the levels of periodontopathogenic bacteria in patients with esophageal cancer.

PMID- 30282859 TI - Definition of Prognosis Based on Lymph Node Metastasis and Elevation of Serum C Reactive Protein for Patients with Gastric Carcinoma Treated with Curative Resection. AB - PURPOSE: The aim of this study was to develop prognostic criteria based on the combination of nodal metastasis and preoperative elevation of serum C-reactive protein (CRP) for patients with gastric carcinoma that have been treated with curative resection. METHODS: Three hundred and twenty patients with gastric carcinoma who had been treated with curative resection were enrolled. One point was provided for each incidence of nodal metastasis and preoperative elevation of serum CRP and we examined whether this cumulative score system could provide a strict stratification of survival. RESULTS: Significant differences regarding survival were observed both between patients with scores of 0 and 1 (P < 0.0001) and between patients with scores of 1 and 2 (P < 0.0001). Multivariate analysis showed that the cumulative score (P = 0.0003) and the depth of the tumor (P = 0.016) were independent prognostic indicators. CONCLUSIONS: Criteria for the prediction of prognosis in gastric carcinoma treated with curative resection based on tumor-related and host-related factors could provide a strict stratification. J.

PMID- 30282860 TI - Novel formula using triceps skinfold thickness to revise the Cockcroft-Gault equation for estimating renal function in Japanese bedridden elderly patients. AB - In recumbent elderly patients, creatinine clearance (eCCr) estimated by the Cockcroft-Gault (CG) equation may not necessarily reflect renal function. We aimed to develop a novel formula to revise the CG equation using anthropometric measurements in bedridden elderly patients and evaluate its clinical utility. The subjects included 77 bedridden Japanese patients aged ? 65, hospitalized at Naruto Yamakami Hospital. The actual CCr (mCCr) value was measured using the 24 hour urine collection method. Anthropometric data, such as skeletal muscle mass, body fat mass (BFM), and triceps skinfold thickness (TSF), were collected. We established a novel formula to estimate CCr(BFM) or CCr(TSF) by correcting the eCCr(Enz+0.2) value with BFM or TSF. The stage of classification of renal dysfunctions in patients with eGFR(BFM) or eGFR(TSF) was equivalent to the GFR(control) based on the mCCr. Notably, the novel equation for eCCr based on TSF (eCCr(TSF)), dubbed the "Naruto" formula, can be useful to evaluate renal function in bedridden elderly patients without expensive equipment or additional costs. In this study, mCCr was considered to be the true renal function of the patient, but whether and to what extent mCCr correlates with inulin clearance is unknown. J. Med.

AB - Humans have a high preference for fat, and its excessive intake leads to obesity. This study aimed to investigate the effects of dose-dependent fat intake on biological responses and postprandial appetite sensation in healthy adult subjects. Age and body mass index were 29 +/- 1 years and 21.1 +/- 0.4 kg/m2, respectively. We conducted a randomized, crossover trial and measured laboratory data and appetite sensation via the visual analog scale. Each participant was provided with four different test meals. They consisted of common, basic foods and contained 75 g liquid glucose and 4 slices of crackers to which 0 g butter (control), 10 g butter (B10), 20 g butter (B20), and 40 g butter (B40) were added, respectively. The results indicated that single ingestion of butter did not influence laboratory values of glucose, insulin, glucose-dependent insulinotropic polypeptide (GIP), total bile acids, or high-sensitivity CRP (hs CRP). Regarding postprandial appetite sensation, appetite ratings for fullness were the highest after the B40 meal (p < 0.05);however, satisfaction ratings were not significantly different after the ingestion of this meal. Ratings were significantly different after the B20 meal. In conclusion, healthy adult subjects experienced fullness and satisfaction after ingesting 20-40 g of butter. J. Med.

AB - Diabetic nephropathy (DN) is the major cause of end-stage renal failure and is associated with increased morbidity and mortality as compared to other causes of renal disease. Albuminuria is often the first clinical indicator of the presence of DN. However, albuminuria or proteinuria is a common symptom in patients with various renal disorders. Therefore, specific biomarkers for the diagnosis of DN are required. A primary hallmark of DN is the progressive damage and death of glomerular podocytes, resulting in the leaking of proteins into the urine. Urinary exosomes released by podocytes are microvesicles containing information of the originated cells. Podocyte-derived signal transduction factors (PDSTFs) are good candidates to assess podocyte injuries. The profile of PDSTFs in urinary exosomes from patients with DN is different from that from patients with minimal change nehrotic syndrome. In addition, PDSTFs molecules in exosomes were derived from primary murine podocytes under high glucose conditions. Among PDSTFs in urinary exosomes, Wilms tumor 1 (WT1) levels reflected damage of diabetic glomeruli in the patients. Urinary exosomal WT1 can predict the decline in eGFR for the following several years. In conclusion, urinary exosomal WT1 is a useful biomarker to improve risk stratification in patients with DN. J.

PMID- 30282863 TI - Effects of FM system fitted into normal hearing ear on speech-in-noise recognition in Japanese school-aged children with unilateral severe-to-profound hearing loss. AB - OBJECTIVES: We examined speech recognition ability of elementary school-aged Japanese children with unilateral hearing loss under noisy environments and then examined the effects of the FM system fitted into their normal hearing ear on their speech recognition ability. METHODS: Twelve children with severe-to profound sensorineural hearing loss and ten age-matched children with bilateral normal hearing received speech recognition test in quiet and noisy environments. Other nine children with severe-to-profound sensorineural hearing loss received speech recognition test with or without the FM receiver fitted to the normal hearing ear in quiet and noisy environments. RESULTS: Signal-to-noise ratio (SNR) in Japanese elementary school classrooms was estimated to be -6.9 dB at a preferential seat. In noisy environment of -5 dB SNR similar to working classrooms, the correct rates of speech recognition test in children with unilateral hearing loss were significantly lower, compared with those in children with bilateral normal hearing. In the noisy environment, the correct rates in children aided by the FM system with unilateral hearing loss were significantly better, compared with unaided ones. CONCLUSION: The results suggested that the FM system is recommended as an audiological management for improvement of speech recognition of children with unilateral hearing loss in noisy classrooms.

AB - The objective of this study was to identify pathological indicators that could be used to identify a subgroup of patients with apparent stage I endometrial cancer who do require retroperitoneal lymphadenectomy. 188 T1 endometrial cancer patients underwent primary surgery at Tokushima University Hospital. We retrospectively evaluated their clinical records and histopathological factors. Systematic lymphadenectomy was performed for 149 patients, and 39 patients (grade 1 with < 5 mm of myometrial invasion) were treated without lymphadenectomy. Lymph node metastases were found in 19 (12.8%) of the lymphadenectomy cases. Twenty four patients with a T1a endometrium-limited lesion did not exhibit lymph node metastasis. Three (3.1%) of the 95 patients with a T1a lesion exhibited lymph node metastasis, and these 3 cases exhibited approximately 50% myometrial invasion. The 39 low-risk patients who did not undergo systematic lymphadenectomy remain alive without recurrence. Systematic lymphadenectomy could be omitted for patients with a grade 1 tumor and minor myometrial invasion of less than 5mm. J. Med. Invest. 65:221-224, August, 2018.

AB - Ectopic fat accumulation is associated with insulin resistance and type 2 diabetes mellitus. Citrus sudachi is an evergreen tree that is found mainly in Tokushima Prefecture in Japan. Previously, it was demonstrated that Citrus sudachi could inhibit the rising trend of blood glucose and fatty acid in human subjects. In the current study, we illustrated the function of methanol extracts from sudachi peel and investigated the mechanism of this effect. We got the five kinds of methanol extracts by using diaion HP-20, and those were named by hydrophobicity from M-F1 to M-F5. Among the 5 kinds of sudachi methanol extracts, only M-F4 significantly decreased the intracellular triglyceride of C2C12 cells. It augmented the AMPK activity and increased the transcription of PPARalpha and its downstream targets CPT-1b and UCP2. In conclusion, M-F4 improved the lipid metabolism possibly through AMPK, PPARalpha and their downstream targets like CPT 1b and UCP2. Furthermore, this extract may be useful for preventing obesity and diabetes related diseases. J. Med. Invest. 65:225-230, August, 2018. PMID- 30282866 TI - Assessment of renal function in Japanese children with malignancies using serum cystatin C. AB - Several factors besides renal function influence serum cystatin C (CysC) levels. The present study evaluates the value of serum CysC and the equation for CysC based estimated glomerular filtration rate (CysC-eGFR) for Japanese children with malignancies. We collected information at 36 time points from 13 patients aged <= 17 years with malignancies. We assessed tumor activity, cell recovery phase after chemotherapy, neutropenia phase, inflammation response and medication with granulocyte-colony stimulating factor, steroid, and levothyroxine as risk factors associated with serum CysC levels. Although no 24-h creatinine clearance (CCr) data collected at 36 time points indicated renal dysfunction, serum CysC levels were above and below the reference values at four and five time points, respectively. The frequency of elevated serum CysC levels was higher in patients without therapy or with stable or progressive disease than among those with a complete or partial response (p = 0.0046). The correlation coefficient between CCr and CysC-eGFR was 0.355 (p = 0.054), but this improved to 0.663 (p = 0.0010) when restricted to patients with a complete or partial response. Levels of serum CysC might become elevated regardless of renal function, and CysC-eGFR might become unpredictable during the active phase of tumors. J. Med. Invest. 65:231 235, August, 2018. PMID- 30282868 TI - Effect of wild grape on the signaling of histamine H1 receptor gene expression responsible for the pathogenesis of allergic rhinitis. AB - As expression level of allergic disease-sensitive genes are correlated with allergic symptom severity, suppression of these gene expressions could be good therapeutics. We have demonstrated that PKCdelta signaling and NFAT signaling, involve in histamine H1 receptor (H1R) and IL-9 gene expressions, respectively, are responsible for the pathogenesis of allergic rhinitis. We explore anti allergic compounds that suppress these signaling pathways and found that wild grape (WG) contains such compounds. Here, we investigated the effect of WG hot water extract (WGE) on the signaling pathways for PKCdelta-mediated H1R and NFAT mediated IL-9 gene expressions. WGE suppressed histamine/PMA-induced H1R gene up regulation in HeLa cells. Toluene-2,4-diisocyanate (TDI)-induced H1R mRNA elevation in TDI-sensitized rats was also suppressed by WGE treatment. Treatment with WGE in combination with Awa-tea, suppresses NFAT signaling-mediated IL-9 gene, markedly alleviated nasal symptoms. Furthermore, WGE suppressed PMA-induced IL-33 gene up-regulation in Swiss 3T3 cells. Data suggest that combination of WGE, suppresses PKCdelta signaling with Awa-tea, suppresses NFAT signaling would have distinct clinical and therapeutic advantages as a substitute for anti allergic drugs. In addition, as the expression level of IL-33 mRNA was correlated with the blood eosinophils number in patients with pollinosis, WG could alleviate eosinophilic inflammation through the suppression of IL-33 gene expression.

PMID- 30282867 TI - Association of short-term ozone exposure with pulmonary function and respiratory symptoms in schoolchildren:A panel study in a western Japanese city. AB - The average annual ozone levels have been increasing in Japan, even though the high ozone levels have decreased in recent years. There is limited information on the relationship between ozone exposure, pulmonary function, and respiratory symptoms in schoolchildren in Japan. The aim of this study was to investigate the effects of short-term ozone exposure on pulmonary function and respiratory symptoms in Japanese schoolchildren. Afternoon peak expiratory flow (PEF) values and respiratory symptom scores were recorded daily in 276 schoolchildren from September to October 2016 and from January to February 2017. The association of daily ozone levels with PEF was assessed using a linear mixed model and that with respiratory symptoms was evaluated by generalized estimating equations logistic regression analysis. There was a significant association of daily ozone levels with PEF values. A 13.6-ppb increment in the interquartile range for ozone exposure was significantly associated with a decrease in PEF of -3.67 L/min (95% confidence interval -4.73, -2.61). However, increased ozone levels were not associated with an increased risk of respiratory symptoms. Our present findings suggest that more attention should be paid to the potential adverse effects of short-term ozone exposure on pulmonary function in schoolchildren. J. Med.

AB - BACKGROUND: Dermatomyositis (DM) and polymyositis (PM) often have association with interstitial lung disease (ILD) which have disease specific autoantibody. METHODOLOGY: We reviewed medical records of DM/PM associated ILD from January 2000 to December 2017 according to the autoantibody. RESULT: We identified 52 patients, of whom 30 were antibody negative, 18 had anti aminoacyl-tRNA synthetases (ARS) antibodies and 4 had anti melanoma differentiation-associated gene (MDA)-5 antibody. In high resolution computed tomography (HRCT) of the chest, area of ground glass opacity (GGO), consolidation, and lung tip consolidation were more extensive in anti MDA-5 antibody positive patients (p=0.051, p=0.026, and p=0.027, respectively). Among laboratory findings, GOT had strong correlations with CPK (r=0.889, p < 0.001), and LDH (r=0.910, p < 0.001). Among roentgenographic findings, there were moderate correlations between GGO and consolidation (r=0.668, p < 0.001), and between reticular shadow and traction bronchiectasis (p=0.633, p < 0.001). ILD patients with anti MDA-5 antibodies had decreased survival (1.00 vs 84.3, 22.9 months, p < 0.001). CONCLUSION: ILD patients with anti ARS antibody had intense inflammation, but reversible fibrosis and good prognosis. On the other hand, anti MDA-5 antibody positive ILD patients had shorter survival. Extent of parenchymal shadow and serum GOT were useful indicator of disease activity of PM/DM associated ILD patients in our cohort. J. Med. Invest. 65:251-257, August, 2018. PMID- 30282870 TI - Human airway trypsin-like protease (HAT) is released into saliva. AB - We first discovered human airway trypsin-like protease (HAT) in human mucoid sputum. Precursor HAT (47 kDa), a cell surface type II transmembrane serine protease, is proteolyzed to mature HAT (27 kDa). Hitherto, HAT has not been detected in other biological fluids except for human sputum. We aimed to clarify whether human saliva contains mature HAT. Trypsin-like protease was isolated from saliva of healthy volunteers by a method adopted for isolation of HAT from sputum using Boc-Phe-Ser-Arg-MCA as the substrate. Biochemical properties of purified protease were similar to those of recombinant HAT (rHAT). HAT concentration in saliva was measured by ELISA, and immunoreactive HAT:total protein ratio (ng/mg) in saliva samples from healthy subjects was similar to that in mucoid sputum. RT PCR showed that HAT mRNA was expressed in human gingival epithelial cells but not in gingival fibroblasts. Both indirect immunofluorescence and western blotting using monoclonal antibody for alpha-smooth muscle actin (alpha-SMA;a myofibroblast marker) showed that HAT enhanced alpha-SMA fiber expression in gingival fibroblasts. These results indicate that both mucoid sputum and saliva from healthy subjects have similar concentrations of mature HAT, and HAT is related to certain physiological functions and pathological states of myofibroblasts in the oral cavity.

AB - The aim of this study was to clarify the experiences of husbands present at their wives' emergency cesarean sections. Semi-structured interviews were conducted for nine husbands who attended their wives' emergency cesarean sections. The results were analyzed using a qualitative inductive approach. Several categories such as [wife's labor pain will be unbearable if I look], [situation was beyond one's control], and [sense of relief experienced by midwife care] were extracted from the husbands' experiences the need for an emergency cesarean section was established. Additional categories such as [sense of relief at cesarean section decision], [convincing oneself], and [anxiety for life and hope for safety] were extracted at the time of the emergency cesarean section decision. Other categories [anxiety while waiting for prolonged periods], [ease of mind with family], and [pleasure in meeting the baby] were extracted from the husbands' experiences while waiting for their wives' cesarean section. Finally, the categories of [unloading of responsibilities], [to thank my wife], and [remaining anxious and fearful] were extracted from the husbands' experiences on their wives return to their hospital rooms. Husbands were anxious about the life and safety of their wife and child, and considered their futures in case of an unexpected occurrence. J. Med. Invest. 65:268-273, August, 2018. PMID- 30282872 TI - Age-dependent texture features in skeletal muscle ultrasonography. AB - Texture analysis characterizes regions in an image by their texture content and has been utilized to infer the underlying structures of medical images such as skeletal muscles. Although potentially useful in tissue diagnosis and assessing disease progression of neuromuscular diseases, the use of texture analysis in such purposes are limited, due to lack of information such as effects of aging. Thus, we performed texture analysis of medial gastrocnemius in healthy individuals form their 20s to late 80s. Among the 283 texture features in 6 classes, the features related to histogram, co-occurrence matrix, absolute gradient, and wavelet were correlated to age in 17-40% of the parameters, while none of the features related to run-length matrix and autoregressive model had significant correlation to age. This study showed that age-dependency in many texture features are present and need to be taken into account in elucidating the clinical significance. By contrast, the features related to run-length matrix and autoregressive model could have clinical utility. J. Med. Invest. 65:274-279, August, 2018. PMID- 30282873 TI - Attachment Disorder and Early Media Exposure: Neurobehavioral symptoms mimicking autism spectrum disorder. AB - Many studies have reported many adverse effects of children's use of media. These effects include reduced cognitive development and hyperactivity and attention disorders. Although it has been recommended that child be kept away from the media during the early developmental period, many modern parents use the media as a way to calm their children. Consequently, these children lack the opportunity to form selective attachments by reduced social engagement. These children's symptoms occasionally mimic autism spectrum disorder (ASD). However, few studies have examined the symptoms children develop with early media exposure. Here, we present a boy exposed to the media during his early development who was diagnosed with attachment disorder. He was unable to make eye contact and was hyperactive and had delayed language development, like children with ASD. His symptoms improved dramatically after he was prevented from using all media and encouraged to play in other ways. After this treatment, he would make eye contact, and talked about playing with their parents. Simply avoiding the media and playing with others can change the behavior of a child with ASD-like symptoms. It is important to understand the symptoms caused by attachment disorder and early media exposure. J. Med. Invest. 65:280-282, August, 2018. PMID- 30282874 TI - A case of solitary paraaortic lymph node recurrence of lung squamous cell carcinoma after resection. AB - Solitary abdominal paraaortic lymph node recurrence after radical lung cancer surgery is very rare. Here, we report a case of a solitary abdominal paraaortic lymph node recurrence of lung squamous cell carcinoma (SCC). A 63-year-old man was diagnosed with lung SCC (cT1cN0M0 stage IA3), underwent a video-assisted right lower lobectomy (ND2a-1), and the pathological findings showed SCC (pT1cN0M0 stage IA3). The EGFR mutation and ALK translocation statuses of SCC were negative, and adjuvant therapy was not performed. Follow-up positron emission tomography - computed tomography (PET/CT) showed a solitary fluorodeoxyglucose (FDG)-concentrated region in the swollen paraaortic lymph node. A paraaortic lymph node biopsy was performed by open laparotomy, to determine the precise diagnosis and identify the genetic status. Pathological findings revealed that the paraaortic lymph node contained poorly differentiated SCC, which was thought to metastasize from the lung cancer. The genetic status of the lymph node recurrence revealed a lack of EGFR mutations, ALK translocations, and ROS1 mutations, while the tumor proportion score (TPS) of PD-L1 was 55%, and we therefore administered pembrolizumab, an immune checkpoint inhibitor. Biopsies are very important for achieving precise diagnoses and determining the genetic statuses of tumors, since molecular-targeting drugs and immune checkpoint inhibitors are available. J. Med.

AB - Hyperbaric oxygen therapy (HBOT) for carbon monoxide (CO) poisoning is widely performed to prevent delayed neuropsychiatric syndrome. Although HBOT can generally be performed with safety, the appropriate management of HBOT still remains unestablished. A 31-year-old man was transferred to our facility to undergo HBOT in a multiplace chamber with a diagnosis of CO poisoning. The first HBOT session ended uneventfully. During the second HBOT session, the patient suddenly experienced convulsive seizures. The accompanying doctor administered intravenous propofol to stop the convulsion and terminated the HBOT. Soon after the convulsion, the patient developed frothy secretions through the endotracheal tube with impaired oxygenation. Head computed tomography scan showed no abnormalities, suggesting the seizure was associated with complications of HBOT. A chest X-ray revealed bilateral pulmonary edema, and echocardiography revealed normal cardiac function, indicating that the pulmonary edema resulted from HBOT or neurogenic mechanism secondary to the seizure. The patient's respiratory status improved without recurrence of the seizure and no delayed neurological sequelae was seen afterwards. Here we report unexpected rare adverse events during HBOT. Hyperbaric oxygen therapy for acute indications should be performed in multiplace chambers, with appropriate preparation and medical equipment. J. Med. Invest. 65:286-288, August, 2018.

Computed tomography showed multiple lung tumors in addition to a huge tumor in the left breast. A needle biopsy brought about a histological diagnosis of ductal carcinoma. A simple mastectomy was performed and a histological examination using the resected specimen demonstrated a coexistence of an adenoid structure and a false ductal structure according the histologic characteristics of adenoid cystic carcinoma, which is quite rare among breast tumors.

AB - Natural rubber latex (NRL) allergy is one of the most important causes of severe anaphylaxis during medical intervention. We report a pediatric case of latex allergy with multiple surgical histories. A 12-year-old girl developed anaphylactic shock during the pyeloplasty for ureteropelvic junction restenosis. Latex gloves or medications used during the surgery were suspected to be the cause of anaphylactic shock. We diagnosed her latex allergy on the basis of the results that serum latex-specific IgE, skin prick tests of extract from NRL gloves and recombinant Hev b 6.02 solution were positive. Basophil activation test of NRL gloves was also positive, supporting the diagnosis of immediate allergic reactions caused by NRL. It was speculated that a history of multiple surgeries in infancy became a trigger of sensitization to latex in this patient. Reoperation after the diagnosis of NRL allergy was carried out in a latex-free environment and completed without any allergic symptoms. It would be necessary to perform the pre-screening of latex allergy to prevent the onset of latex allergy especially in the patients with multiple surgical histories. J. Med.

AB - In patients with esophageal cancer, esophageal conduit necrosis is a catastrophic complication of esophagectomy that requires surgical restoration. Because such patients are generally fatigued, less-invasive surgery is encouraged whenever possible. Therefore, we trim the sternum minimally above the healthy part of the gastric conduit, expose its surface, and then make anastomoses between the remnant esophagus and the exposed gastric conduit using a free jejunal graft through a retrosternal-subcutaneous route. The risk involved with this procedure is low, because we avoid manipulation of the heavily inflamed lesion due to mediastinitis. J. Med. Invest. 65:296-298, August, 2018. PMID- 30282879 TI - In Vitro and In Vivo Detection of Drug-induced Apoptosis Using Annexin V conjugated Ultrasmall Superparamagnetic Iron Oxide (USPIO): A Pilot Study. AB - PURPOSE: To investigate the binding potential of newly developed Annexin V conjugated ultrasmall superparamagnetic iron oxide (V-USPIO) for detection of drug-induced apoptosis in vitro and in vivo. METHODS: Apoptotic cells induced by camptothecin were incubated with or without Annexin V-USPIO at a concentration of 0.089 mmol Fe/L in vitro. T2 values of the two cell suspensions were measured by 0.47T nuclear magnetic resonance (NMR) spectrometer. Tumor-bearing mice were subjected to 1.5T MR scanner at 2 h after intraperitoneal injection of etoposide and cyclophosphamide. Following the pre-contrast T1- and T2-weighted imaging (0 h), the post-contrast scan was performed at 2, 4, 6 and 24 h after intravenous injection of Annexin V-USPIO (100 MUmol Fe/kg). As a control, MRI was also obtained at 4 h after injection of USPIO without Annexin V. The ratio of tumor signal intensity (SI) on post-MRI for that on pre-MRI (Post/Pre-SI ratio) was calculated. After scanning, tumors were resected for pathological analysis to evaluate the distribution of iron and apoptotic cells. RESULTS: The suspension of apoptotic cells incubated with Annexin V-USPIO showed shorter T2 value than that without it. On T1-weighted imaging post/pre-SI ratio at 4 h after injection of Annexin V-USPIO showed 1.46, while after injection of USPIO without Annexin V was 1.17. The similar distribution of iron and apoptotic cells was observed in concordance with high signal intensity area on post-T1-weighted imaging. CONCLUSION: A newly developed Annexin V-USPIO could have the potential for detection of drug-induced apoptosis. PMID- 30282880 TI - PD-L1 Expression in Non-Small-Cell Lung Cancer Including Various Adenocarcinoma Subtypes. AB - PURPOSE: Knowledge regarding programmed death-ligand 1 (PD-L1) expression in lung cancer is limited. We aim to clarify PD-L1-positive expression in non-small-cell lung cancer (NSCLC), including adenocarcinoma subtypes. METHODS: In all, 90 NSCLC specimens containing various adenocarcinoma subtypes, in addition to squamous cell carcinoma and large-cell carcinoma were selected. PD-L1 was immunohistochemically stained by murine monoclonal antibody clone 22C3. RESULTS: When PD-L1-positive expression was defined by tumor proportion score (TPS) >=1%, the positive cases were 0/11 in adenocarcinoma in situ, 0/12 in minimally invasive adenocarcinoma, 1/10 in lepidic predominant adenocarcinoma, 1/13 in papillary predominant adenocarcinoma, 8/14 in acinar predominant adenocarcinoma, 6/11 in solid predominant adenocarcinoma, 0/3 in micropapillary predominant adenocarcinoma, 0/4 in invasive mucinous adenocarcinoma, 4/9 in squamous cell carcinoma, and 2/3 in large-cell carcinoma. PD-L1 positivity was higher in males, smokers, advanced pathologic stages, positive vessel invasion, and positive lymphatic invasion. Postoperative survival analysis revealed that PD-L1-positive expression was a significantly worse prognostic factor in univariate analysis for recurrence-free survival (RFS). CONCLUSION: PD-L1-positive tumors were frequent in acinar predominant adenocarcinoma and solid predominant adenocarcinoma than other adenocarcinoma subtypes. PD-L1 expression seemed to increase according to pathologic tumor progression, suggesting a worse postoperative prognosis in NSCLC patients. PMID- 30282881 TI - Correlations Between Serum Cholesterol and Vascular Lesions in Fabry Disease Patients. AB - BACKGROUND: Fabry disease is an X-linked lysosomal storage disorder and shows globotriosylceramide (Gb3) accumulation in multiple organs, resulting from a deficiency of alpha-galactosidase. In patients with Fabry disease, cardiovascular disease occurs at an early age. Previous studies have shown that serum levels of high-density lipoprotein-cholesterol (HDL-C) increase in this disease, yet its clinical significance for cardiovascular disease remains unclear. Methods and Results: In order to determine why the serum HDL-cholesterol is high in various cardiovascular diseases of Fabry disease patients, we evaluated the serum lipid profiles, ocular vascular lesions, and levels of serum vascular endothelial growth factor (VEGF) and intercellular adhesion molecule-1 in 69 patients with Fabry disease diagnosed by genetic examination. The serum HDL-C/total cholesterol (T-Chol) ratio was significantly high, especially in male patients (41.5+/-1.7%) regardless of body mass index. Ocular vascular lesions were more likely to occur in female patients with a high HDL-C/T-Chol ratio compared with most male patients. Female patients with a high HDL-C/T-Chol ratio also presented a high serum VEGF level, suggesting that vascular endothelium dysfunction and arteriosclerotic changes progress more severely than in patients with a normal HDL-C/T-Chol ratio. In most patients, enzyme replacement therapy improved serum Gb3 and lyso-Gb3 levels, but these Gb3 and lyso-Gb3 still remained higher than in healthy controls, which appears to result in continuous vascular arteriosclerotic changes. CONCLUSIONS: We concluded that increased low-density lipoprotein cholesterol uptake to the vascular wall caused by endothelial dysfunction is likely to contribute to the high HDL-C/T-Chol ratio observed in Fabry disease patients. PMID- 30282882 TI - Positive Association of High Leptin Level and Abdominal Aortic Calcification in Men - The Prospective MINOS Study. AB - BACKGROUND: Severe abdominal aortic calcification (AAC) points to high cardiovascular risk and leptin stimulates arterial calcification; however, clinical data on their association are scarce. We studied the link between serum leptin and AAC severity and progression, and the effect of smoking and lipid levels, on this association in men. Methods and Results: At baseline, 548 community-dwelling men aged 50-85 years underwent blood collection and lateral lumbar spine radiography. In 448 men, X-ray was repeated after 3 and 7.5 years. AAC was assessed using Kauppila's semiquantitative score. In multivariable models, high leptin was associated with higher odds of severe AAC (odds ratio [OR]=1.71 per SD, 95% confidence interval [CI]: 1.22-2.40). The odds of severe AAC were the highest in men who had elevated leptin levels and either were ever smokers (OR=9.22, 95% CI: 3.43-24.78) or had hypertriglyceridemia (vs. men without these characteristics). Higher leptin was associated with greater AAC progression (OR=1.34 per SD, 95% CI: 1.04-1.74). The risk of AAC progression was the highest in men who had elevated leptin levels and either were current smokers or had high low-density lipoprotein-cholesterol levels (OR=5.91, 95% CI: 2.46 14.16 vs. men without these characteristics). These links remained significant after adjustment for baseline AAC and in subgroups defined according to smoking and low-density lipoprotein-cholesterol levels. CONCLUSIONS: In older men, high leptin levels are associated with greater severity and rapid progression of AAC independent of smoking, low-density lipoprotein-cholesterol or triglycerides. PMID- 30282884 TI - A rapid risk assessment of African swine fever introduction and spread in Japan based on expert opinions. AB - A rapid risk assessment was conducted using a questionnaire composed of 10 questions asking experts in African swine fever (ASF) to identify and rank the potential risk factors associated with the introduction and spread of ASF in Japan. The experts participating in this risk assessment considered illegal food import, followed by transport routes and foreign workers, to be the most relevant pathway of ASF introduction into Japan. Kanto and Kyushu were identified as the most likely regions for ASF introduction. All experts agreed that China is the most likely source of ASF introduction into Japan. Most Japanese experts were of the view that the risk of ASF spread if introduced into Japan would be low, while foreign experts considered the risk to be moderate or high. Most experts answered that wild boars would play an important role in the persistence of ASF if the disease were to spread in Japan. PMID- 30282883 TI - How does Toxoplama gondii invade host cells? AB - Toxoplasma gondii is a highly prevalent protozoon that can infect all warm blooded animals, including humans. It is frequently used as an Apicomplexan parasite model in research. In this review, the invasion mechanism of T. gondii is described as a representative Apicomplexan parasite. The invasion machinery of T. gondii consists of the moving junction and the glideosome, which is a specific motor system for Apicomplexan parasites. I provide details about the moving junction, parasite-secreted proteins and host adhesion receptors, the glideosome, and calcium signaling, which generates the power for the gliding mobility of T. gondii.

AB - The Bethesda System for Reporting Thyroid Cytopathology has recently been revised in 2017 (TBSRTC 2017). This study aimed to evaluate the impact of modifying the diagnostic criteria in TBSRTC 2017 at a single institute. We retrospectively reviewed cytological specimens of 10,399 thyroid nodules submitted for thyroid fine-needle aspiration cytology. Among them, 56 atypia of undetermined significance or follicular lesion of undetermined significance (AUS/FLUS) nodules, 16 suspicious for malignancy (SFM) nodules, and 8 malignant nodules were re-categorized into follicular neoplasm or suspicious for a follicular neoplasm (FN/SFN). The incidence of FN/SFN was increased by 0.8%, while that of AUS/FLUS, SFM, and malignant nodule was decreased by 0.5%, 0.2%, and 0.1%, respectively. In nine (60%) of the 15 nodules that were re-classified from AUS/FLUS to FN/SFN nodules and re-aspiration was performed, it was possible to judge whether they were benign or malignant. Of the 24 patients with FN/SFN nodules originally diagnosed with SFM or malignant, 16 were followed up without surgical resection. In conclusion, TBSRTC 2017 only caused minor changes in the incidence of each diagnostic category. TBSRTC 2017 was revised to avoid false positives owing to noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) that account for >10% of papillary thyroid carcinomas; however, it is not necessary in low frequency NIFTP institutes or countries. In Japan, we propose active surveillance as an accepted option for clinically managing AUS/FLUS, FN/SFN, SFM, or malignant nodules having favorable benign clinical findings or being part of the low-risk group.

AB - Plasma adiponectin levels and expression of its receptors, AdipoRs are decreased in obesity, which cause insulin resistance and diabetes. AdipoR-deficient mice exhibit insulin resistance and impaired glucose tolerance. Moreover, newly identified AdipoR agonists not only improve insulin resistance but prolong lifespan shortened by obesity via AdipoR. Furthermore, efforts to promote structure-based drug discovery research at our laboratory have led to the first ever successful crystallization of AdipoR as well as to clarification of their structures. Structural analysis of AdipoRs as key molecules in lifestyle-related diseases is thus expected to lead not only to the acceleration of structure-based drug discovery but to the elucidation of novel aspects of the AdipoR structures and functions in the years to come. Finally, with the development of novel AdipoR targeted antidiabetic agents also capable of prolonging lifespan, the attainment of healthy longevity may finally be brought within reach.

AB - BACKGROUND: Both twin pregnancies with complete hydatidiform mole and coexisting normal fetus (CHMCF) and partial hydatidiform mole can be found in association with a live fetus and a placenta displaying a molar degeneration. Two cases of CHMCF using magnetic resonance imaging (MRI) for a diagnosis are reported. CASE: In the first, CHMCF was suspected at 12 weeks of gestation. At 18 weeks of gestation, the existence of molar placenta and a sac separating from fetus and normal placenta was clearly depicted on MRI. At 19 weeks of gestations, she had termination of pregnancy because of a development of gestational trophoblastic neoplasia (GTN) and started chemotherapy. In the second case, CHMCF was suspected at 14 weeks of gestation. MRI demonstrated the existence of molar placenta and a sac separating from fetus and normal placenta. She chose induced abortion and there was no evidence of GTN during the 1 year-follow up period. Pathological examination in both cases was consistent with a complete hydration mole and a coexisting normal female fetus. CONCLUSION: MRI was useful for an accurate diagnosis for CHMCF. PMID- 30282892 TI - The Correlation Between Length of Work and Nasal Mucociliary Transport Time of Gas/Fuel Station Workers. AB - Gasoline contains toxic substances such as benzene, toluene, ethylbenzene, xylene (BTEX) that negatively influence gas/fuel station workers' health via continuous inhalation, causing loss of cilia and epithelial cell necrosis of the nasal mucosa. The aim of this study is to determine the correlation between length of work with nasal mucociliary transport time (NMCTT) of the gas/fuel station workers This study used a cross sectional design. The data were obtained from anamnesis, physical and NMCTT examinations of gas station workers in Yogyakarta, during November 2013. Inclusion criteria were: 1) 18-55 years old, 2) free of nasal topical medication for 10 days. Exclusion criterion: 1) acute rhinitis, 2) chronic sinusitis, 3) ever had nasal trauma, 4) ever had nasal surgery, 5) allergic rhinitis, and/or 6) septal deviation. Correlation analyses between length of work and NMCTT of gas station workers used Spearman correlation test with alpha 5% level of significance (p < 0.05). From 38 subjects, 27 (71.1%) were men and 11 (28.9%) women. Median length of work was 7.37 years, and NMCTT: 10.84 +/- 5.60 minutes. Spearman's correlation test results between length of work and NMCTT showed (R): 0.578 (p = 0.001). Based on the results of this study, it can be concluded that there is a positive correlation between length of work with NMCTT of gas station workers. PMID- 30282893 TI - Associated Factors of Psychological Distress among Japanese NICU Nurses in Supporting Bereaved Families Who Have Lost Children. AB - PURPOSE: This study aimed (1) to examine the current status of psychological distress experienced by neonatal intensive care unit (NICU) nurses in supporting bereaved families, (2) to identify the factors associated with psychological distress, and (3) to understand the professional characteristics of nurses experiencing high psychological distress by comparing the study results with those of pediatricians. METHODS: We sent questionnaires to 64 NICUs. The psychological distress of nurses was classified into two groups based on the frequency of psychological distress experienced and analyzed using the chi2 test and Fisher's exact test. A multiple logistic regression analysis was used to investigate the factors related to psychological distress. RESULTS: Of the 384 nurse respondents, 190 (49.5%) reported having supported bereaved families, 169 of who were included in the analysis. A total of 123 nurses (72.8%) reported high levels of psychological distress. Our study revealed that the use of coping methods is associated with high psychological distress. The comparison with pediatricians revealed that nurses were significantly more likely to be female and had fewer years of working experience. Nurses were also significantly more likely to use coping methods and to experience high psychological distress. CONCLUSION: Clarifying the coping methods for psychological distress in supporting bereaved families may be necessary, and nurses need to identify appropriate coping methods. In nursing education, information on psychological distress related to children's deaths and bereavement care should be conveyed from the early stage and nurses must obtain preliminary knowledge. The creation of a bereavement follow-up system is recommended. PMID- 30282894 TI - Hyperbilirubinemia in Term Newborns Needing Phototherapy within 48 Hours after Birth in a Japanese Birth Center. AB - BACKGROUND: Hyperbilirubinemia in term newborns needing phototherapy within 48 hours after birth, early-onset hyperbilirubinemia, has not been evaluated in recent Japanese healthy birth centers. In this study, we sought to determine the cause of early-onset hyperbilirubinemia in a Japanese healthy birth center and to evaluate the 1992 Kobe University phototherapy treatment criterion requiring total serum bilirubin (TSB) and unbound bilirubin (UB). METHODS: In this retrospective observational study, we collected data on newborns diagnosed with early-onset hyperbilirubinemia between 2009 and 2016 at the Chibune General Hospital. Causes of the disease were investigated, as well as which index (TSB or UB) was used for treatment decisions. RESULTS: Overall, 76 term newborns were included in the analysis. Twenty-seven newborns (36%) found the cause (ABO blood type incompatibility [n=17, 22%], polycythemia [n=8, 11%], and cephalohematoma [n=2, 3%]). However, 49 newborns (64%) did not find any causes (i.e., idiopathic hyperbilirubinemia). Of these, 27 observed more than 5% weight loss from birth weight. Seventy (92%) newborns had abnormal TSB only, and 5 (7%) had abnormal TSB and UB values. Only 1 (1%) newborn with only abnormal UB values received phototherapy. CONCLUSIONS: Altogether, data from this Japanese healthy birth center suggest that many apparently healthy newborns with or without excessive weight loss develop early-onset hyperbilirubinemia. In the 1992 Kobe University phototherapy treatment criterion, TSB, not UB, was the main index used to make treatment decisions in these patients.

AB - AIM: This study aimed to explore novel metabolite biomarker candidates for screening oral squamous cell carcinoma (OSCC). PATIENTS & METHODS: We collected plasma samples from 48 patients with OSCC and 29 with an oral disease and conducted a plasma metabolomics analysis of patients with OSCC using gas chromatography mass spectrometry. Then, we used the cross-validation procedure to ensure the accuracy of biomarker candidates. RESULTS: We selected four biomarker candidates against OSCC. Their sensitivity was more than 90%, and the AUC was over 0.9 according to the receiver operating characteristic curve analysis. CONCLUSIONS: The findings of this study suggest four potential metabolites as biomarkers for OSCC screening. PMID- 30282896 TI - Analysis of Forming Limits in Sheet Metal Forming with Pattern Recognition Methods. Part 2: Unsupervised Methodology and Application. AB - The forming limit curve (FLC) is used in finite element analysis (FEA) for the modeling of onset of sheet metal instability during forming. The FLC is usually evaluated by achieving forming measurements with optical measurement system during Nakajima tests. Current evaluation methods such as the standard method according to DIN EN ISO 12004-2 and time-dependent methods limit the evaluation range to a fraction of the available information and show weaknesses in the context of brittle materials that do not have a pronounced constriction phase. In order to meet these challenges, a supervised pattern recognition method was proposed, whose results depend on the quality of the expert annotations. In order to alleviate this dependence on experts, this study proposes an unsupervised classification approach that does not require expert annotations and allows a probabilistic evaluation of the onset of localized necking. For this purpose, the results of the Nakajima tests are examined with an optical measuring system and evaluated using an unsupervised classification method. In order to assess the quality of the results, a comparison is made with the time-dependent method proposed by Volk and Hora, as well as expert annotations, while validated with metallographic investigations. Two evaluation methods are presented, the deterministic FLC, which provides a lower and upper limit for the onset of necking, and a probabilistic FLC, which allows definition of failure quantiles. Both methods provide a necking range that shows good correlation with the expert opinion as well as the results of the time-dependent method and metallographic examinations.

AB - The 24-h day-containing physical activity, sedentary behaviour and sleep-in pre school children has not yet been extensively investigated. The aim of the current study was to investigate pre-schoolers' compliance with the 24-h movement behaviour guidelines (i.e., three hours/day total physical activity, a maximum of one hour/day of screen time and 10-13 h sleep/night). In total, 595 pre-schoolers (53.3% boys, mean age: 4.2 years) provided complete data for the three behaviours. Physical activity was objectively measured with accelerometers, while screen time and sleep were parent-reported through questionnaires. The proportion of pre-schoolers complying with the 24-h movement behaviour guidelines was calculated on weekdays and on weekend days. Low compliance rates were found: 10.1% on weekdays and only 4.3% on weekend days. The majority of pre-schoolers complied with the sleep duration guidelines (>90% on weekdays and weekend days), followed by the screen time guidelines (61% on weekdays and 28% on weekend days). The lowest compliance rates were found for physical activity (<20% on weekdays and weekend days). Overall, low percentages of pre-schoolers complying with the 24-h movement behaviour guidelines were found, and the lowest compliance was found for physical activity. PMID- 30282899 TI - A Study on Neonatal Intake of Oleanolic Acid and Metformin in Rats (Rattus norvegicus) with Metabolic Dysfunction: Implications on Lipid Metabolism and Glucose Transport. AB - : Metabolic syndrome, a cluster of different disorders which include diabetes, obesity and cardiovascular diseases, is a global epidemic that is growing at an alarming rate. The origins of disease can be traced back to early developmental stages of life. This has increased mortalities and continues to reduce life expectancies of individuals across the globe. The aim of this study was to investigate the sub-acute and long term effects of neonatal oral administration of oleanolic acid and metformin on lipids (free fatty acids, FFAs) and genes associated with lipid metabolism and glucose transport using a neonatal rat experimental model. In the first study, seven days old pups were randomly grouped into control-distilled water (DW); oleanolic acid (60 mg/kg), metformin (500 mg/kg), high fructose diet (20% w/v, HF), oleanolic acid (OA) + high fructose diet (OA + HF), and Metformin + high fructose diet (MET + HF) groups. The pups were treated for 7 days, and then terminated on postnatal day (PD) 14. In the second study, rat pups were initially treated similarly to study 1 and weaned onto normal rat chow and plain drinking water on PD 21 till they reached adulthood (PD112). Tissue and blood samples were collected for further analyses. Measurement of the levels of free fatty acids (FFAs) was done using gas chromatography-mass spectrometry. Quantitative polymerase chain reaction (qPCR) was used to analyze the gene expression of glut-4, glut-5, fas, acc-1, nrf-1 and cpt-1 in the skeletal muscle. The results showed that HF accelerated accumulation of saturated FFAs within skeletal muscles. The HF fed neonatal rats had increased stearic acid, which was associated with decreased glucose, suppressed expression of glut-4, glut-5, nrf-1 and cpt-1 genes, and increased expression of acc-1 (p < 0.01) and fas. OA + HF and MET + HF treated groups had increased mono- and polyunsaturated FFAs; oleic, and octadecadienoic acids than the HF group. These unsaturated FFAs were associated with increased glut-4, glut-5 and nrf-1 (p < 0.01) and decreased acc-1 and fas (p < 0.05) in both OA + HF and MET + HF treated groups. CONCLUSIONS: The present study shows that neonatal oral administration of oleanolic acid and metformin potentially protects against the development of fructose-induced metabolic dysfunction in the rats in both short and long time periods. PMID- 30282900 TI - Social and Emotional Fears and Worries Influencing the Quality of Life of Female Celiac Disease Patients Following a Gluten-Free Diet. AB - The gluten-free diet is effective in the majority of celiac disease (CD) patients, but it is burdensome and may influence quality of life (QoL). The aim of the study was to analyze the social and emotional fears and worries influencing the QoL of female CD patients following a gluten-free (GF) diet, as well as to indicate the sociodemographic interfering factors. The study was conducted on a group of 251 female CD patients, while emotional, social and worries subscales of the Celiac Disease Questionnaire (CDQ) were applied, as well as purchase-related emotions and behaviors were assessed. Respondents declaring worse economic status obtained significantly lower scores in the emotional, social and worries subscales of the CDQ than respondents declaring better economic status, while for other factors (CD duration, GFD adherence, BMI, place of residence and educational level) no significant association was stated in the multi-factor analysis. Moreover, respondents declaring worse economic status more often declared that a bad mood affected their purchase decisions than did respondents declaring better economic status. It was stated, that the economic status of CD patient could be one of the most important factors influencing their social and emotional fears and worries. It may be supposed that low economic status may lead some CD patients to choose to relieve stress by purchasing GF products instead of other products. PMID- 30282901 TI - Effects of a Change from an Indoor-Based Total Mixed Ration to a Rotational Pasture System Combined with a Moderate Concentrate Feed Supply on the Health and Performance of Dairy Cows. AB - In spring, the transition from a total mixed ration (TMR) to pasture requires metabolic adaptions for the cow. It had been shown that supply of low amounts of concentrate after transition to full-time grazing caused energy deficits, resulting in a lower milking performance and changes in a variety of variables indicative for energy metabolism. The present study aimed to investigate how a moderate concentrate supply (4.5 kg dry matter cow/day) after transition to pasture influences health and production indicators. Over a 12-week trial period dairy cows were observed during transition from confinement to pasture (pasture group: PG) and compared to cows fed TMR indoors (confinement group: CG). On average, the PG consumed less feed and energy than the CG and mobilized body reserves, which is mirrored in a decrease of body condition and various fat depots. These effects were paralleled by elevated serum concentrations of non esterified fatty acids and ketone bodies as well as an increase in liver fat content. The physical activity (elevated walking, eating, decreasing rumination time) of the PG was significantly higher than that of the CG, which intensified the energy deficiency and resulted in a lower milk yield. In conclusion, the moderate concentrate supply was insufficient to counterbalance the lower energy intake from pasture during transition. PMID- 30282902 TI - Luteolin Targets the Toll-Like Receptor Signaling Pathway in Prevention of Hepatic and Adipocyte Fibrosis and Insulin Resistance in Diet-Induced Obese Mice. AB - This study was to investigate the protective role of luteolin on inflammation mediated metabolic diseases, focusing on the role of luteolin in the modulation of the Toll-like receptor (TLR) signaling pathway. C57BL/6J mice were fed a normal, high-fat, or high-fat + 0.005% (w/w) luteolin diet for 16 weeks. Luteolin improved chronic low-grade inflammation by modulating the TLR signaling pathway, resulting in reduced pro-inflammatory cytokines and macrophage accumulation. A positive relationship was detected between gene expressions of Tlr5, Map2k7, Mapk12, Mapk13, and Mapk9 and lipogenesis in epididymal white adipose tissue (eWAT) of luteolin-treated mice, which was linked to attenuation of hepatic lipotoxicity by increasing free fatty acid (FFA) flux to the WAT. Luteolin prevented fibrosis by decreasing extracellular matrix accumulation and cathepsin gene expressions, while enhancing the hepatic antioxidant system. Emr1 and Ccl7, important markers inducing low-grade inflammation, were affected by advanced age and greater body weight, which were normalized by luteolin treatment. Luteolin improved insulin resistance by normalizing pancreatic islet dysfunction and differentially modulating the plasma glucagon-like peptide-1 and gastric inhibitory polypeptide levels. Our results suggest that luteolin ameliorates diet induced obesity and its comorbidities. Overall, this study provides novel insights into the effect of luteolin on the links among adiposopathy, insulin resistance, hepatic steatosis, and fibrosis. PMID- 30282903 TI - Prescribing Variation in General Practices in England Following a Direct Healthcare Professional Communication on Mirabegron. AB - INTRODUCTION: Pharmacovigilance may detect safety issues after marketing of medications, and this can result in regulatory action such as direct healthcare professional communications (DHPC). DHPC can be effective in changing prescribing behaviour, however the extent to which prescribers vary in their response to DHPC is unknown. This study aims to explore changes in prescribing and prescribing variation among general practitioner (GP) practices following a DHPC on the safety of mirabegron, a medication to treat overactive bladder (OAB). METHODS: This is an interrupted time series study of English GP practices from 2014-2017. National Health Service (NHS) Digital provided monthly statistics on aggregate practice-level prescribing and practice characteristics (practice staff and registered patient profiles, Quality and Outcomes Framework indicators, and deprivation of the practice area). The primary outcome was monthly mirabegron prescriptions as a percentage of all OAB drug prescriptions and we assessed the change following a DHPC issued by the European Medicines Agency in September 2015. The DHPC stated mirabegron use was contraindicated with severe uncontrolled hypertension and cautioned with hypertension. Variation between practices in mirabegron prescribing before and after the DHPC was assessed using the systematic component of variation (SCV). Multilevel segmented regression with random effects quantified the change in level and trend of prescribing after the DHPC. Practice characteristics were assessed for their association with a reduction in prescribing following the DHPC. RESULTS: This study included 7408 practices. During September 2015, 88.9% of practices prescribed mirabegron and mirabegron comprised a mean of 8.2% (SD 6.8) of OAB prescriptions. Variation between practices was classified as very high and the median SCV did not change significantly (p = 0.11) in the six months after the September 2015 DHPC (12.4) compared to before (11.6). Before the DHPC, the share of mirabegron over all OAB drug prescriptions increased by 0.294 (95% confidence interval (CI), 0.287, 0.301) percentage points per month. There was no significant change in the month immediately after the DHPC (-0.023, 95% CI -0.105 to 0.058), however there was a significant reduction in trend (-0.036, 95% CI -0.049 to -0.023). Higher numbers of registered patients, patients aged >=65 years, and practice area deprivation were associated with having a significant decrease in level and slope of mirabegron prescribing post-DHPC. CONCLUSION: Variation in mirabegron prescribing was high over the study period and did not change substantively following the DHPC. There was no immediate prescribing change post-DHPC, although the monthly growth did slow. Knowledge of the degree of variation in and determinants of response to safety communications may allow those that do not change prescribing habits to be provided with additional support. PMID- 30282905 TI - Effects of Short Transport and Prolonged Fasting in Beef Calves. AB - Marketing is a stressful process for beef calves, because they are removed from their environment, often weaned just before loading, loaded, transported, and unloaded. It also involves extended periods without food and water and mixing with unfamiliar animals in an unknown environment. Some studies have shown that calves sold through markets are exposed to extended fasting periods even when they undergo only short transportation times. The aim of this controlled study was to determine the consequences for beef calves of a short transportation time followed by a prolonged time without food and water on their tympanic temperature (TT), maximum eye temperature (MET), blood variables related to stress, and live weight. Ten calves were transported for 3 h and then kept in an outdoor pen for 21 h, completing a 24 h fasting period. Sampling took place before loading, after transport and unloading, and then after completing 24 h without food and water. TT, MET, blood glucose, and creatine kinase (CK) increased significantly after transportation. Live weight decreased across sample times (mean of 10 kg per calf after 24 h of fasting), which was consistent with the higher concentration of beta-HB found after fasting. Further studies to measure the actual consequences of true, commercial marketing on calf welfare and productivity are needed. PMID- 30282904 TI - 10,12 Conjugated Linoleic Acid-Driven Weight Loss Is Protective against Atherosclerosis in Mice and Is Associated with Alternative Macrophage Enrichment in Perivascular Adipose Tissue. AB - The dietary fatty acid 10,12 conjugated linoleic acid (10,12 CLA) promotes weight loss by increasing fat oxidation, but its effects on atherosclerosis are less clear. We recently showed that weight loss induced by 10,12 CLA in an atherosclerosis-susceptible mouse model with characteristics similar to human metabolic syndrome is accompanied by accumulation of alternatively activated macrophages within subcutaneous adipose tissue. The objective of this study was to evaluate whether 10,12 CLA-mediated weight loss was associated with an atheroprotective phenotype. Male low-density lipoprotein receptor deficient (Ldlr /-) mice were made obese with 12 weeks of a high-fat, high-sucrose diet feeding (HFHS: 36% fat, 36% sucrose, 0.15% added cholesterol), then either continued on the HFHS diet with or without caloric restriction (CR), or switched to a diet with 1% of the lard replaced by either 9,11 CLA or 10,12 CLA for 8 weeks. Atherosclerosis and lipid levels were quantified at sacrifice. Weight loss in mice following 10,12 CLA supplementation or CR as a weight-matched control group had improved cholesterol and triglyceride levels, yet only the 10,12 CLA-treated mice had improved en face and aortic sinus atherosclerosis. 10,12 CLA supplemented mice had increased lesion macrophage content, with enrichment of surrounding perivascular adipose tissue (PVAT) alternative macrophages, which may contribute to the anti-atherosclerotic effect of 10,12 CLA. PMID- 30282906 TI - Simultaneous Intake of Euglena Gracilis and Vegetables Synergistically Exerts an Anti-Inflammatory Effect and Attenuates Visceral Fat Accumulation by Affecting Gut Microbiota in Mice. AB - We determined whether the benefits provided by the consumption of Euglena gracilis (Euglena), which is a unicellular photosynthesizing green alga and rich in insoluble dietary fiber paramylon, can be enhanced by the co-consumption of vegetables that are rich in soluble dietary fiber. Nine-week-old male C57BL/6J mice were divided into four groups: group 1 received normal diet, whereas groups 2, 3 and 4 received normal diet containing 0.3% paramylon, 1.0% Euglena, or 1.0% Euglena plus 0.3% vegetables (barley leaf, kale and ashitaba), respectively. Mice were fed ad libitum until 18 weeks of age. Euglena intake significantly decreased serum markers of inflammation and co-consumption of vegetables enhanced this reduction. Notably, we observed an increase in the fraction of beneficial bacteria producing short-chain fatty acids, a reduction in harmful bacteria that cause inflammation and an increase in short-chain fatty acid production. Visceral fat accumulation was also reduced. Subsequent analyses showed that co-consumption of Euglena with vegetables reduced adipocyte area, suppressed the expression of genes related to fatty acid synthesis and increased the expression of genes related to adipocyte growth and lipolysis. Therefore, co-consumption of Euglena with vegetables enhanced its anti-inflammatory effect and the inhibitory effect on visceral fat accumulation likely by modulating the composition of gut microbiota. PMID- 30282909 TI - "I Feel Sorry for Them": Australian Meat Consumers' Perceptions about Sheep and Beef Cattle Transportation. AB - Concern for livestock welfare is significantly increasing in many parts of the world. One area of concern is the transportation of livestock. Using qualitative research methods, this research explores the concerns of Australian meat consumers related to livestock transportation practices, both on land by truck and on sea by ship. Participants were predominantly concerned about animals being "crammed" into trucks and ships, and the long distances over which livestock were transported. Likely contributors to these reactions are the high visibility of truck transport in urban areas, and recent media and political attention to the live-export issue in Australia. We argue that participants' concerns about transport are arising for a variety of reasons, including anthropomorphic tendencies, genuine concern for the welfare of farm animals, and emotional responses related to the discomfort experienced by meat consumers when they are reminded of the meat-animal connection. Given the importance of transport to the red-meat production industry, these results suggest that the sector may need to reconsider some of their practices and increase transparency and communication about the practices, which they utilise to ensure good animal welfare. PMID- 30282907 TI - Rubella Virus Strain-Associated Differences in the Induction of Oxidative Stress Are Independent of Their Interferon Activation. AB - Rubella virus (RV) infection impacts cellular metabolic activity in a complex manner with strain-specific nutritional requirements. Here we addressed whether this differential metabolic influence was associated with differences in oxidative stress induction and subsequently with innate immune response activation. The low passaged clinical isolates of RV examined in this study induced oxidative stress as validated through generation of the reactive oxygen species (ROS) cytoplasmic hydrogen peroxide and mitochondrial superoxide. The addition of the cytoplasmic and mitochondrial ROS scavengers N-acetyl-l-cysteine and MitoTEMPO, respectively, reduced RV-associated cytopathogenicity and caspase activation. While the degree of oxidative stress induction varied among RV clinical isolates, the level of innate immune response and interferon-stimulated gene activation was comparable. The type III IFNs were highly upregulated in all cell culture systems tested. However, only pre-stimulation with IFN beta slightly reduced RV replication indicating that RV appears to have evolved the ability to counteract innate immune response mechanisms. Through the data presented, we showed that the ability of RV to induce oxidative stress was independent of its capacity to stimulate and counteract the intrinsic innate immune response. PMID- 30282908 TI - APS8 Delays Tumor Growth in Mice by Inducing Apoptosis of Lung Adenocarcinoma Cells Expressing High Number of alpha7 Nicotinic Receptors. AB - The alkylpyridinium polymer APS8, a potent antagonist of alpha7 nicotinic acetylcholine receptors (nAChRs), selectively induces apoptosis in non-small cell lung cancer cells but not in normal lung fibroblasts. To explore the potential therapeutic value of APS8 for at least certain types of lung cancer, we determined its systemic and organ-specific toxicity in mice, evaluated its antitumor activity against adenocarcinoma xenograft models, and examined the in vitro mechanisms of APS8 in terms of apoptosis, cytotoxicity, and viability. We also measured Ca2+ influx into cells, and evaluated the effects of APS8 on Ca2+ uptake while siRNA silencing of the gene for alpha7 nAChRs, CHRNA7. APS8 was not toxic to mice up to 5 mg/kg i.v., and no significant histological changes were observed in mice that survived APS8 treatment. Repetitive intratumoral injections of APS8 (4 mg/kg) significantly delayed growth of A549 cell tumors, and generally prevented regrowth of tumors, but were less effective in reducing growth of HT29 cell tumors. APS8 impaired the viability of A549 cells in a dose-dependent manner and induced apoptosis at micro molar concentrations. Nano molar APS8 caused minor cytotoxic effects, while cell lysis occurred at APS8 >3 uM. Furthermore, Ca2+ uptake was significantly reduced in APS8-treated A549 cells. Observed differences in response to APS8 can be attributed to the number of alpha7 nAChRs expressed in these cells, with those with more AChRs (i.e., A549 cells) being more sensitive to nAChR antagonists like APS8. We conclude that alpha7 nAChR antagonists like APS8 have potential to be used as therapeutics for tumors expressing large numbers of alpha7 nAChRs. PMID- 30282911 TI - Metabolomic Analyses Reveal Extensive Progenitor Cell Deficiencies in a Mouse Model of Duchenne Muscular Dystrophy. AB - Duchenne muscular dystrophy (DMD) is a musculoskeletal disorder that causes severe morbidity and reduced lifespan. Individuals with DMD have an X-linked mutation that impairs their ability to produce functional dystrophin protein in muscle. No cure exists for this disease and the few therapies that are available do not dramatically delay disease progression. Thus, there is a need to better understand the mechanisms underlying DMD which may ultimately lead to improved treatment options. The muscular dystrophy (MDX) mouse model is frequently used to explore DMD disease traits. Though some studies of metabolism in dystrophic mice exist, few have characterized metabolic profiles of supporting cells in the diseased environment. Using nontargeted metabolomics we characterized metabolic alterations in muscle satellite cells (SCs) and serum of MDX mice. Additionally, live-cell imaging revealed MDX-derived adipose progenitor cell (APC) defects. Finally, metabolomic studies revealed a striking elevation of acylcarnitines in MDX APCs, which we show can inhibit APC proliferation. Together, these studies highlight widespread metabolic alterations in multiple progenitor cell types and serum from MDX mice and implicate dystrophy-associated metabolite imbalances in APCs as a potential contributor to adipose tissue disequilibrium in DMD. PMID- 30282910 TI - Environmental Electronic Vape Exposure from Four Different Generations of Electronic Cigarettes: Airborne Particulate Matter Levels. AB - Electronic cigarettes (e-cigs) were introduced into the market in 2006 and their technological features have evolved substantially over time. Currently, there are four different generations of e-cigs that are broadly considered less harmful than the use of combusted tobacco products although passive exposure to aerosols often occurs in public spaces and indoor environments. The study aim was to evaluate the levels of airborne particulate matter (PM) emitted during the use of all the four generations of e-cigs, testing different use modalities. PM10, PM4, PM2.5 and PM1 were measured through a Dusttrak TM II Aerosol Monitor, for a total of 20 independent experiments. All tested e-cigs devices produced PM during their use, and PM10 was almost made of PM1 size fraction. In addition, we observed a progressive increase in PM emission from the first to the fourth generation, and an upward trend of PM1 emitted by the fourth generation e-cig with an increase in the operating power. The results showed that, whatever the model adopted, passive vaping does occur. This finding supports the need for legislative interventions to regulate the e-cigs use in public places and other enclosed environments, in order to protect the health of any subject who is potentially exposed. PMID- 30282912 TI - Milieu for Endothelial Differentiation of Human Adipose-Derived Stem Cells. AB - Human adipose-derived stem cells (hASCs) have been shown to differentiate down many lineages including endothelial lineage. We hypothesized that hASCs would more efficiently differentiate toward the endothelial lineage when formed as three-dimensional (3D) spheroids and with the addition of vascular endothelial growth factor (VEGF). Three conditions were tested: uncoated tissue culture polystyrene (TCPS) surfaces that induced a 2D monolayer formation; elastin-like polypeptide (ELP)-collagen composite hydrogel scaffolds that induced encapsulated 3D spheroid culture; and ELP-polyethyleneimine-coated TCPS surfaces that induced 3D spheroid formation in scaffold-free condition. Cells were exposed to endothelial differentiation medium containing no additional VEGF or 20 and 50 ng/mL of VEGF for 7 days and assayed for viability and endothelial differentiation markers. While endothelial differentiation media supported endothelial differentiation of hASCs, our 3D spheroid cultures augmented this differentiation and produced more von Willebrand factor than 2D cultures. Likewise, 3D cultures were able to uptake LDL, whereas the 2D cultures were not. Higher concentrations of VEGF further enhanced differentiation. Establishing angiogenesis is a key factor in regenerative medicine. Future studies aim to elucidate how to produce physiological changes such as neoangiogenesis and sprouting of vessels which may enhance the survival of regenerated tissues.

AB - This study focuses on the design, synthesis, biological evaluation, and computer aided structure-activity relationship (SAR) analysis for a novel group of aromatic triazine-methylpiperazines, with an hydantoin spacer between 1,3,5 traizine and the aromatic fragment. New compounds were synthesized and their affinities for serotonin 5-HT6, 5-HT1A, 5-HT2A, 5-HT7, and dopamine D2 receptors were evaluated. The induced-fit docking (IFD) procedure was performed to explore the 5-HT6 receptor conformation space employing two lead structures. It resulted in a consistent binding mode with the activity data. For the most active compounds found in each modification line, anti-obesity and anti-depressive-like activity in vivo, as well as "druglikeness" in vitro, were examined. Two 2 naphthyl compounds (18 and 26) were identified as the most active 5-HT6R agents within each lead modification line, respectively. The 5-(2-naphthyl)hydantoin derivative 26, the most active one in the series (5-HT6R: Ki = 87 nM), displayed also significant selectivity towards competitive G-protein coupled receptors (6 197-fold). Docking studies indicated that the hydantoin ring is stabilized by hydrogen bonding, but due to its different orientation, the hydrogen bonds form with S5.44 and N6.55 or Q6.58 for 18 and 26, respectively. Compound 26 exerted anxiolytic-like and antidepressant-like activities. Importantly, it demonstrated anti-obesity properties in animals fed palatable feed, and did not show toxic effects in vitro. PMID- 30282916 TI - Anti-Diabetic Medications for the Pharmacologic Management of NAFLD. AB - As a chronic disease encompassing a wide spectrum of liver-related histologic damage, nonalcoholic fatty liver disease (NAFLD) is becoming a global epidemic with significant impacts on all-cause morbidity and mortality. Insulin resistance and type 2 diabetes mellitus predispose individuals to NAFLD and related complications. Therefore, timely intervention with anti-diabetic medications may prevent and delay the development of NAFLD or have a therapeutic implication. The focus of this review is to evaluate the evidence supporting the efficacy of anti diabetic medications in the treatment of NAFLD. While many of these anti-diabetic agents have shown to improve biochemical parameters, their effect on hepatic histology is limited. Among anti-diabetic medications, only thiazolidinediones and glucagon-like peptide-1 receptor agonists demonstrate significant improvement in hepatic histology. PMID- 30282915 TI - Prodigiosin-Emerged PI3K/Beclin-1-Independent Pathway Elicits Autophagic Cell Death in Doxorubicin-Sensitive and -Resistant Lung Cancer. AB - Prodigiosin (PG) belongs to a family of prodiginines isolated from gram-negative bacteria. It is a water insoluble red pigment and a potent proapoptotic compound. This study elucidates the anti-tumor activity and underlying mechanism of PG in doxorubicin-sensitive (Dox-S) and doxorubicin-resistant (Dox-R) lung cancer cells. The cytotoxicity and cell death characteristics of PG in two cells were measured by MTT assay, cell cycle analysis, and apoptosis/autophagic marker analysis. Then, the potential mechanism of PG-induced cell death was evaluated through the phosphatidylinositol-4,5-bisphosphate 3-kinase-p85/Protein kinase B /mammalian target of rapamycin (PI3K-p85/Akt/mTOR) and Beclin 1/phosphatidylinositol-4,5-bisphosphate 3-kinase-Class III (Beclin-1/PI3K-Class III) signaling. Finally, in vivo efficacy was examined by intratracheal inoculation and treatment. There was similar cytotoxicity with PG in both Dox-S and Dox-R cells, where the half maximal inhibitory concentrations (IC50) were all in 10 MUM. Based on a non-significant increase in the sub-G1 phase with an increase of microtubule-associated proteins 1A/1B light chain 3B phosphatidylethanolamine conjugate (LC3-II), the cell death of both cells was categorized to achieve autophagy. Interestingly, an increase in cleaved-poly ADP ribose polymerase (cleaved-PARP) also showed the existence of an apoptosis sensitive subpopulation. In both Dox-S and Dox-R cells, PI3K-p85/Akt/mTOR signaling pathways were reduced, which inhibited autophagy initiation. However, Beclin-1/PI3K-Class III downregulation implicated non-canonical autophagy pathways were involved in PG-induced autophagy. At completion of the PG regimen, tumors accumulated in the mice trachea and were attenuated by PG treatment, which indicated the efficacy of PG for both Dox-S and Dox-R lung cancer. All the above results concluded that PG is a potential chemotherapeutic agent for lung cancer regimens regardless of doxorubicin resistance. PMID- 30282914 TI - Molecular and Immunohistochemical Markers with Prognostic and Predictive Significance in Liver Metastases from Colorectal Carcinoma. AB - Despite the significant recent achievements in the diagnosis and treatment of colorectal cancer (CRC), the prognosis of these patients has currently plateaued. During the past few years, the opportunity to consider multiple treatment modalities (including surgery and other locoregional treatments, systemic therapy, and targeted therapy) led to the research of novel prognostic and predictive biomarkers in CRC liver metastases (CRCLM) patients. In this review, we seek to describe the current state of knowledge of CRCLM biomarkers and to outline impending clinical perspectives, in particular focusing on the cutting edge tools available for their characterization. PMID- 30282917 TI - Effect of Selected Commercial Plasticizers on Mechanical, Thermal, and Morphological Properties of Poly(3-hydroxybutyrate)/Poly(lactic acid)/Plasticizer Biodegradable Blends for Three-Dimensional (3D) Print. AB - This paper explores the influence of selected commercial plasticizers structure, which are based on esters of citric acid, on mechanical and thermal properties of Poly(3-hydroxybutyrate)/Poly(lactic acid)/Plasticizer biodegradable blends. These plasticizers were first tested with respect to their miscibility with Poly(3 hydroxybutyrate)/Poly(lactic acid) (PHB/PLA) blends using a kneading machine. PHB/PLA/plasticizer blends in the weight ratio (wt %) of 60/25/15 were then prepared by single screw and corotating meshing twin screw extruders in the form of filament for further three-dimensional (3D) printing. Mechanical, thermal properties, and shape stability (warping effect) of 3D printed products can be improved just by the addition of appropriate plasticizer to polymeric blend. The goal was to create new types of eco-friendly PHB/PLA/plasticizers blends and to highly improve the poor mechanical properties of neat PHB/PLA blends (with majority of PHB) by adding appropriate plasticizer. Mechanical properties of plasticized blends were then determined by the tensile test of 3D printed test samples (dogbones), as well as filaments. Measured elongation at break rapidly enhanced from 21% for neat non-plasticized PHB/PLA blends (reference) to 328% for best plasticized blends in the form of filament, and from 5% (reference) to 187% for plasticized blends in the form of printed dogbones. The plasticizing effect on blends was confirmed by Modulated Differential Scanning Calorimetry. The study of morphology was performed by the Scanning Electron Microscopy. Significant problem of plasticized blends used to be also plasticizer migration, therefore the diffusion of plasticizers from the blends after 15 days of exposition to 110 degrees C in the drying oven was investigated as their measured weight loss. Almost all of the used plasticizers showed meaningful positive softening effects, but the diffusion of plasticizers at 110 degrees C exposition was quite extensive. The determination of the degree of disintegration of selected plasticized blend when exposed to a laboratory-scale composting environment was executed to roughly check the "biodegradability". PMID- 30282918 TI - N Balance Studies Emphasize the Superior Protein Quality of Pig Diets at High Inclusion Level of Algae Meal (Spirulina platensis) or Insect Meal (Hermetia illucens) when Adequate Amino Acid Supplementation Is Ensured. AB - Two age-dependent nitrogen (N) balance studies (average body mass 25 and 60 kg) utilized 16 male castrated piglets and 16 barrows to measure N utilization parameters of diets with complete substitution of SBM by alternative protein sources (SM, HM), but different AA fortifications. Lysine supplementation up to 80% of the recommended lysine (Lys) supply in diets HM (A) and SM (A) yielded similar protein quality data (63.6 +/- 2.1 and 63.7 +/- 3.4). Surprisingly, only in piglet diet HM (AA) did the extended AA supplementation (Lys, methionine (Met), threonine (Thr)) enhance protein quality (72.8 +/- 6.7) significantly (p = 0.004). Similar trends were observed in growing pigs. However, when the level of histidine (His) in diet SM (AA) was increased, feed protein quality (71.8 +/- 1.3) was significantly (p < 0.001) improved indicating the importance of adequate His supply in diets with a complete substitution of SBM by the algae meal (SM) under study. AA efficiency data extend the possibilities to explain the observed responses on protein quality. When an adequate AA balancing in the diet is guaranteed, from nutritional point of view both of the alternative proteins may replace SBM in pig diets. PMID- 30282919 TI - Fetal Brain Infection Is Not a Unique Characteristic of Brazilian Zika Viruses. AB - The recent emergence of Zika virus (ZIKV) in Brazil was associated with an increased number of fetal brain infections that resulted in a spectrum of congenital neurological complications known as congenital Zika syndrome (CZS). Herein, we generated de novo from sequence data an early Asian lineage ZIKV isolate (ZIKV-MY; Malaysia, 1966) not associated with microcephaly and compared the in vitro replication kinetics and fetal brain infection in interferon alpha/beta receptor 1 knockout (IFNAR1-/-) dams of this isolate and of a Brazilian isolate (ZIKV-Natal; Natal, 2015) unequivocally associated with microcephaly. The replication efficiencies of ZIKV-MY and ZIKV-Natal in A549 and Vero cells were similar, while ZIKV-MY replicated more efficiently in wild-type (WT) and IFNAR-/- mouse embryonic fibroblasts. Viremias in IFNAR1-/- dams were similar after infection with ZIKV-MY or ZIKV-Natal, and importantly, infection of fetal brains was also not significantly different. Thus, fetal brain infection does not appear to be a unique feature of Brazilian ZIKV isolates. PMID- 30282921 TI - Preparation of Reduction-Responsive Camptothecin Nanocapsules by Combining Nanoprecipitation and In Situ Polymerization for Anticancer Therapy. AB - Stimuli-responsive systems for controlled drug release have been extensively explored in recent years. In this work, we developed a reduction-responsive camptothecin (CPT) nanocapsule (CPT-NC) by combining nanoprecipitation and in situ polymerization using a polymerized surface ligand and a disulfide bond containing crosslinker. Dissolution rate studies proved that the CPT-NCs have robust drug-release profiles in the presence of glutathione (GSH) owing to the division of the disulfide bond crosslinker which triggers the collapse of the polymer layer. Furthermore, the in vitro investigations demonstrated that the CPT NCs exhibited a high-cellular uptake efficiency and cytotoxicity for cancer cells of squamous cell carcinoma (SCC-15). Our approach thus presents an effective intracellular drug delivery strategy for anticancer therapy. PMID- 30282922 TI - Consuming Genistein Improves Survival Rates in the Absence of Laxative in DeltaF508-CF Female Mice. AB - Genistein is a naturally occurring isoflavone found in soy. Genistein has been shown to increase the open probability of the most common cystic fibrosis (CF) disease-associated mutation, ?F508-CFTR. Mice homozygous for the ?F508 mutation are characterized with severe intestinal disease and require constant laxative treatment for survival. This pathology mimics the intestinal obstruction (meconium ileus) seen in some cystic fibrosis patients. This study tested whether dietary supplementation with genistein would reduce the dependence of the ?F508 CF mouse model on laxatives for survival, thereby improving mortality rates. At weaning (21 days), homozygous ?F508 mice were maintained on one of three diet regimens for a period of up to 65 days: normal diet, normal diet plus colyte, or genistein diet. Survival rates for males were as follows: standard diet (38%, n = 21), standard diet plus colyte (83%, n = 42) and genistein diet (60%, n = 15). Survival rates for females were as follows: standard diet (47%, n = 19), standard diet plus colyte (71%, n = 38), and genistein diet (87%, n = 15). Average weight of male mice fed genistein diet increased by ~2.5 g more (p = 0.006) compared to those with colyte treatment. Genistein diet did not change final body weight of females. Expression of intestinal SGLT-1 increased 2-fold (p = 0.0005) with genistein diet in females (no change in males, p = 0.722). Expression of GLUT2 and GLUT5 was comparable between all diet groups. Genistein diet reduced the number of goblet cells per micrometer of crypt depth in female (p = 0.0483), yet was without effect in males (p = 0.7267). The results from this study demonstrate that supplementation of diet with genistein for ~45 days increases the survival rate of female ?F508-CF mice (precluding the requirement for laxatives), and genistein only improves weight gain in males. PMID- 30282920 TI - Oxidative Stress in the Male Germline: A Review of Novel Strategies to Reduce 4 Hydroxynonenal Production. AB - Germline oxidative stress is intimately linked to several reproductive pathologies including a failure of sperm-egg recognition. The lipid aldehyde 4 hydroxynonenal (4HNE) is particularly damaging to the process of sperm-egg recognition as it compromises the function and the stability of several germline proteins. Considering mature spermatozoa do not have the capacity for de novo protein translation, 4HNE modification of proteins in the mature gametes has uniquely severe consequences for protein homeostasis, cell function and cell survival. In somatic cells, 4HNE overproduction has been attributed to the action of lipoxygenase enzymes that facilitate the oxygenation and degradation of omega 6 polyunsaturated fatty acids (PUFAs). Accordingly, the arachidonate 15 lipoxygenase (ALOX15) enzyme has been intrinsically linked with 4HNE production, and resultant pathophysiology in various complex conditions such as coronary artery disease and multiple sclerosis. While ALOX15 has not been well characterized in germ cells, we postulate that ALOX15 inhibition may pose a new strategy to prevent 4HNE-induced protein modifications in the male germline. In this light, this review focuses on (i) 4HNE-induced protein damage in the male germline and its implications for fertility; and (ii) new methods for the prevention of lipid peroxidation in germ cells. PMID- 30282923 TI - QSAR and Classification Study on Prediction of Acute Oral Toxicity of N-Nitroso Compounds. AB - To better understand the mechanism of in vivo toxicity of N-nitroso compounds (NNCs), the toxicity data of 80 NNCs related to their rat acute oral toxicity data (50% lethal dose concentration, LD50) were used to establish quantitative structure-activity relationship (QSAR) and classification models. Quantum chemistry methods calculated descriptors and Dragon descriptors were combined to describe the molecular information of all compounds. Genetic algorithm (GA) and multiple linear regression (MLR) analyses were combined to develop QSAR models. Fingerprints and machine learning methods were used to establish classification models. The quality and predictive performance of all established models were evaluated by internal and external validation techniques. The best GA-MLR-based QSAR model containing eight molecular descriptors was obtained with Q2loo = 0.7533, R2 = 0.8071, Q2ext = 0.7041 and R2ext = 0.7195. The results derived from QSAR studies showed that the acute oral toxicity of NNCs mainly depends on three factors, namely, the polarizability, the ionization potential (IP) and the presence/absence and frequency of C-O bond. For classification studies, the best model was obtained using the MACCS keys fingerprint combined with artificial neural network (ANN) algorithm. The classification models suggested that several representative substructures, including nitrile, hetero N nonbasic, alkylchloride and amine-containing fragments are main contributors for the high toxicity of NNCs. Overall, the developed QSAR and classification models of the rat acute oral toxicity of NNCs showed satisfying predictive abilities. The results provide an insight into the understanding of the toxicity mechanism of NNCs in vivo, which might be used for a preliminary assessment of NNCs toxicity to mammals. PMID- 30282924 TI - Fish Intake, Circulating Mercury and Mortality in Renal Transplant Recipients. AB - Marine-derived omega-3 polyunsaturated fatty acids (n-3 PUFAs) are inversely associated with cardiovascular and all-cause mortality in renal transplant recipients (RTRs). Recommendations to increase marine-derived n-3 PUFAs by increasing fish intake may have a drawback in concomitant stimulation of mercury intake, which could lead to higher circulating mercury concentrations and mitigation of otherwise beneficial effects of n-3 PUFAs. We aimed to monitor circulating mercury concentrations, and to prospectively evaluate whether it counteracts the potential association between fish intake and cardiovascular and all-cause mortality in a cohort of RTRs (n = 604, 53 +/- 13 years-old, 57% men) with long-term follow-up (median of 5.4 years; 121 deaths). Circulating mercury concentration (median 0.30 (IQR 0.14-0.63) ug/L) positively associated with fish intake (std. beta = 0.21, p < 0.001). Multivariable-adjusted Cox-proportional hazards regression analyses showed that prior to, and after additional adjustment for circulating mercury concentrations, fish intake was inversely associated with both cardiovascular (HR 0.75, 95% CI 0.58-0.96; and, HR 0.75, 95% CI 0.58-0.97, respectively) and all-cause mortality (HR 0.84, 95% CI 0.72-0.97; and, HR 0.86, 95% CI 0.74-0.99, respectively). Secondary analyses accounting for marine-derived n-3 PUFAs intake revealed associations of similar magnitude. In conclusion, we found no evidence of a counteracting effect conferred by circulating mercury concentrations on the associations between fish and marine-derived n-3 PUFAs intake and the risks of cardiovascular and all-cause mortality in RTRs. PMID- 30282925 TI - Effect of Natural Food Antioxidants against LDL and DNA Oxidative Changes. AB - Radical oxygen species formed in human tissue cells by many endogenous and exogenous pathways cause extensive oxidative damage which has been linked to various human diseases. This review paper provides an overview of lipid peroxidation and focuses on the free radicals-initiated processes of low-density lipoprotein (LDL) oxidative modification and DNA oxidative damage, which are widely associated with the initiation and development of atherosclerosis and carcinogenesis, respectively. The article subsequently provides an overview of the recent human trials or even in vitro investigations on the potential of natural antioxidant compounds (such as carotenoids; vitamins C and E) to monitor LDL and DNA oxidative changes. PMID- 30282927 TI - New Nitrogen Compounds Coupled to Phenolic Units with Antioxidant and Antifungal Activities: Synthesis and Structure-Activity Relationship. AB - A selection of 1-amino-2-arylidenamine-1,2-(dicyano)ethenes 3 was synthesized and cyclized to 2-aryl-4,5-dicyano-1H-imidazoles 4 upon reflux in ethyl acetate/acetonitrile, in the presence of manganese dioxide. These compounds were tested for their antioxidant capacity by cyclic voltammetry, 2,2-diphenyl-1 picrylhydrazyl (DPPH) radical and deoxyribose degradation assays. The minimum inhibitory concentration of all compounds was evaluated against two yeast species, Saccharomyces cerevisiae and Candida albicans. Their toxicity was tested in mammal fibroblasts. Among the synthesised compounds, two presented dual antioxidant/antifungal activity without toxic effects in fibroblasts. The new compounds synthesized in this work are potential biochemical tools and/or therapeutic drugs. PMID- 30282926 TI - Nucleic Acid-Dependent Structural Transition of the Intrinsically Disordered N Terminal Appended Domain of Human Lysyl-tRNA Synthetase. AB - Eukaryotic lysyl-tRNA synthetases (LysRS) have an N-terminal appended tRNA interaction domain (RID) that is absent in their prokaryotic counterparts. This domain is intrinsically disordered and lacks stable structures. The disorder-to order transition is induced by tRNA binding and has implications on folding and subsequent assembly into multi-tRNA synthetase complexes. Here, we expressed and purified RID from human LysRS (hRID) in Escherichia coli and performed a detailed mutagenesis of the appended domain. hRID was co-purified with nucleic acids during Ni-affinity purification, and cumulative mutations on critical amino acid residues abolished RNA binding. Furthermore, we identified a structural ensemble between disordered and helical structures in non-RNA-binding mutants and an equilibrium shift for wild-type into the helical conformation upon RNA binding. Since mutations that disrupted RNA binding led to an increase in non-functional soluble aggregates, a stabilized RNA-mediated structural transition of the N terminal appended domain may have implications on the functional organization of human LysRS and multi-tRNA synthetase complexes in vivo. PMID- 30282929 TI - Bioactive Compounds and Antioxidant Capacity of Rosa rugosa Depending on Degree of Ripeness. AB - Maturity stage affects the bioactive compounds as well as the antioxidant capacity in the fruit. This study was designed to identify and quantify carotenoids, as well as to evaluate vitamin E, vitamin C, antioxidant capacity and total phenolic compounds of Rosa rugosa hips at different degrees of ripeness. HPLC (high performance liquid chromatography) analysis showed different types of carotenoids at different stages of maturity of R. rugosa hips with significant differences (p ? 0.05), where the maximum concentration was observed at late harvesting. In the hips investigated, only alpha-tocopherol was detected, the maximum concentration of both vitamin E and vitamin C was obtained in the orange hips with significant difference (p ? 0.05). On the other hand, the highest hydrophilic and lipophilic TEAC (Trolox equivalent antioxidant capacity) values, as well as total phenolic contents, were determined in the mature hips (red colour) with significant difference (p < 0.0001) and (p < 0.001) respectively, whereas ORAC (oxygen radical absorbance capacity) showed lower activity in the mature hips with significant difference (p ? 0.05). Late harvesting is recommended if a high content of carotenoids is desired, while harvesting should be carried out earlier if a higher vitamin E and vitamin C content is desired, which in turn affects the antioxidants capacity. PMID- 30282928 TI - Effect of Ivabradine on a Hypertensive Heart and the Renin-Angiotensin Aldosterone System in L-NAME-Induced Hypertension. AB - Ivabradine, the selective inhibitor of the If current in the sinoatrial node, exerts cardiovascular protection by its bradycardic effect and potentially pleiotropic actions. However, there is a shortage of data regarding ivabradine's interaction with the renin-angiotensin-aldosterone system (RAAS). This study investigated whether ivabradine is able to protect a hypertensive heart in the model of L-NAME-induced hypertension and to interfere with the RAAS. Four groups (n = 10/group) of adult male Wistar rats were treated as follows for four weeks: control, ivabradine (10 mg/kg/day), L-NAME (40 mg/kg/day), and L-NAME plus ivabradine. L-NAME administration increased systolic blood pressure (SBP) and left ventricular (LV) weight, enhanced hydroxyproline concentration in the LV, and deteriorated the systolic and diastolic LV function. Ivabradine reduced heart rate (HR) and SBP, and improved the LV function. The serum concentrations of angiotensin Ang 1-8 (Ang II), Ang 1-5, Ang 1-7, Ang 1-10, Ang 2-8, and Ang 3-8 were decreased in the L-NAME group and ivabradine did not modify them. The serum concentration of aldosterone and the aldosterone/Ang II ratio were enhanced by L NAME and ivabradine reduced these changes. We conclude that ivabradine improved the LV function of the hypertensive heart in L-NAME-induced hypertension. The protective effect of ivabradine might have been associated with the reduction of the aldosterone level. PMID- 30282930 TI - Validation of a Drug-Related Problem Classification System for the Intermediate and Long-Term Care Setting in Singapore. AB - : Background: This study aims to evaluate the inter-rater reliability and perceived usability of a newly developed drug-related problem (DRP) classification system for use by pharmacists in the intermediate and long-term care (ILTC) setting in Singapore. METHODS: This was a cross-sectional survey study involving the use of a self-administered questionnaire. All 55 pharmacists affiliated to the Pharmaceutical Society of Singapore (PSS) ILTC Pharmacists Workgroup who were above 21 years old and not authors of the classification system were invited to participate. The inter-rater reliability of participants' classification of 46 mock DRP cases using the new DRP classification system was determined using Fleiss's kappa (kappa). Participants' perceived usability of the classification system was evaluated using six items with five-point Likert scales (1-"strongly disagree", 5-"strongly agree"). Results: Thirty-three pharmacists responded to the survey. Overall inter-rater reliability was found to be substantial (kappa = 0.614; 95% CI: 0.611-0.617). All usability items received positive ratings ("strongly agree" or "agree") from at least 69% of participants. Conclusion: The new DRP classification system has substantial external validity and appears to be suitable for use by pharmacists to document and report DRPs in the ILTC setting in Singapore and facilitate evaluation of the impact of pharmaceutical care in the ILTC setting. PMID- 30282931 TI - Glycogen Storage Disease Ib and Severe Periodontal Destruction: A Case Report. AB - Background: Glycogen storage diseases (GSDs) are genetic disorders that result from defects in the processing of glycogen synthesis or breakdown within muscles, liver, and other cell types. It also manifests with impaired neutrophil chemotaxis and neutropenic episodes which results in severe destruction of the supporting dental tissues, namely the periodontium. Although GSD Type Ib cannot be cured, associated symptoms and debilitating oral manifestations of the disease can be managed through collaborative medical and dental care where early detection and intervention is of key importance. This objective of the case report was to describe a child with GSD Ib and its associated oral manifestations with microbial, immunological and histological appearances. Case Presentation: An eight-year-old Hispanic male with a history of GSD type Ib presented with extensive intraoral generalized inflammation of the gingiva, ulcerations and bleeding, and intraoral radiographic evidence of bone loss. Tannerella forsythia was readily identifiable from the biofilm samples. Peripheral blood neutrophils were isolated and a deficient host response was observed by impaired neutrophil migration. Histological evaluation of the soft and hard tissues of the periodontally affected primary teeth showed unaffected dentin and cementum. Conclusions: This case illustrates the association between GSD Ib and oral manifestations of the disease. A multi-disciplinary treatment approach was developed in order to establish healthy intraoral conditions for the patient. Review of the literature identified several cases describing GSD and its clinical and radiographic oral manifestations; however, none was identified where also microbial, immunological, and histological appearances were described. PMID- 30282932 TI - Measurement of Core Body Temperature Using Graphene-Inked Infrared Thermopile Sensor. AB - Continuous and reliable measurements of core body temperature (CBT) are vital for studies on human thermoregulation. Because tympanic membrane directly reflects the temperature of the carotid artery, it is an accurate and non-invasive method to record CBT. However, commercial tympanic thermometers lack portability and continuous measurements. In this study, graphene inks were utilized to increase the accuracy of the temperature measurements from the ear by coating graphene platelets on the lens of an infrared thermopile sensor. The proposed ear-based device was designed by investigating ear canal geometry and developed with 3D printing technology using the Computer-Aided Design (CAD) Software, SolidWorks 2016. It employs an Arduino Pro Mini and a Bluetooth module. The proposed system runs with a 3.7 V, 850 mAh rechargeable lithium-polymer battery that allows long term, continuous monitoring. Raw data are continuously and wirelessly plotted on a mobile phone app. The test was performed on 10 subjects under resting and exercising in a total period of 25 min. Achieved results were compared with the commercially available Braun Thermoscan, Original Thermopile, and Cosinuss One ear thermometers. It is also comprehended that such system will be useful in personalized medicine as wearable in-ear device with wireless connectivity. PMID- 30282934 TI - Synergism of Mild Heat and High-Pressure Pasteurization Against Listeria monocytogenes and Natural Microflora in Phosphate-Buffered Saline and Raw Milk. AB - As many as 99% of illnesses caused by Listeria monocytogenes are foodborne in nature, leading to 94% hospitalizations, and are responsible for the collective annual deaths of 266 American adults. The current study is a summary of microbiological hurdle validation studies to investigate synergism of mild heat (up to 55 degrees C) and elevated hydrostatic pressure (up to 380 MPa) for decontamination of Listeria monocytogenes and natural background microflora in raw milk and phosphate-buffered saline. At 380 MPa, for treatments of 0 to 12 min, d-values of 3.47, 3.15, and 2.94 were observed for inactivation of the pathogen at 4, 25, and 50 degrees C. Up to 3.73 and >4.26 log CFU/mL reductions (p < 0.05) of habituated Listeria monocytogenes were achieved using pressure at 380 MPa for 3 and 12 min, respectively. Similarly, background microflora counts were reduced (p < 0.05) by 1.3 and >2.4 log CFU/mL after treatments at 380 MPa for 3 and 12 min, respectively. Treatments below three min were less efficacious (p >= 0.05) against the pathogen and background microflora, in the vast majority of time and pressure combinations. Results of this study could be incorporated as part of a risk-based food safety management system and risk assessment analyses for mitigating the public health burden of listeriosis. PMID- 30282933 TI - Cell Cycle Changes after Glioblastoma Stem Cell Irradiation: The Major Role of RAD51. AB - "Glioma Stem Cells" (GSCs) are known to play a role in glioblastoma (GBM) recurrence. Homologous recombination (HR) defects and cell cycle checkpoint abnormalities can contribute concurrently to the radioresistance of GSCs. DNA repair protein RAD51 homolog 1 (RAD51) is a crucial protein for HR and its inhibition has been shown to sensitize GSCs to irradiation. The aim of this study was to examine the consequences of ionizing radiation (IR) for cell cycle progression in GSCs. In addition, we intended to assess the potential effect of RAD51 inhibition on cell cycle progression. Five radiosensitive GSC lines and five GSC lines that were previously characterized as radioresistant were exposed to 4Gy IR, and cell cycle analysis was done by fluorescence-activated cell sorting (FACS) at 24, 48, 72, and 96 h with or without RAD51 inhibitor. Following 4Gy IR, all GSC lines presented a significant increase in G2 phase at 24 h, which was maintained over 72 h. In the presence of RAD51 inhibitor, radioresistant GSCs showed delayed G2 arrest post-irradiation for up to 48 h. This study demonstrates that all GSCs can promote G2 arrest in response to radiation-induced DNA damage. However, following RAD51 inhibition, the cell cycle checkpoint response differed. This study contributes to the characterization of the radioresistance mechanisms of GSCs, thereby supporting the rationale of targeting RAD51-dependent repair pathways in view of radiosensitizing GSCs.

AB - To improve the filtration performance and properties of organic solvent nanofiltration (OSN) membranes, we firstly introduce nanoporous silica (SiO2) particles into the polyamide (PA) active layer of polysulfone (PSf) membrane via an interfacial polymerization process. Results from the study revealed that introduction of SiO2 influenced the properties of PSf/PA-SiO2 composite membranes by changing the surface roughness and hydrophilicity. Moreover, results also indicated that nanoporous SiO2 modified membranes showed an improved performance of alcohols solvent permeance. The PSf/PA-SiO2 composite membrane modified by 0.025 wt % of SiO2 reached a permeance of 3.29 L m-2 h-1 bar-1 for methanol and 0.42 L m-2 h-1 bar-1 for ethanol, which were 20.0% and 13.5% higher than the control PSf membrane (permeance of 2.74 L m-2 h-1 bar-1 for methanol and 0.37 L m 2 h-1 bar-1 for ethanol). Conclusively, we demonstrated that the increase of membrane hydrophilicity and roughness were major factors contributing to the improved alcohols solvent permeance of the membranes.

AB - Taste signaling is a complex process that is linked to obesity and its associated metabolic syndromes. The sweet taste is mediated through a heterodimeric G protein coupled receptor (GPCR) in a species-specific manner and at multi-tissue specific levels. The sweet receptor recognizes a large number of ligands with structural and functional diversities to modulate different amplitudes of downstream signaling pathway(s). The human sweet-taste receptor has been extremely difficult to study by biophysical methods due to the difficulty in producing large homogeneous quantities of the taste-receptor protein and the lack of reliable in vitro assays to precisely measure productive ligand binding modes that lead to activation of the receptor protein. We report here a multimodal high throughput assay to monitor ligand binding, receptor stability and conformational changes to model the molecular ligand-receptor interactions. We applied saturation transfer difference nuclear magnetic resonance spectroscopy (STD-NMR) complemented by differential scanning calorimetry (DSC), circular dichroism (CD) spectroscopy, and intrinsic fluorescence spectroscopy (IF) to characterize binding interactions. Our method using complementary NMR and biophysical analysis is advantageous to study the mechanism of ligand binding and signaling processes in other GPCRs.

AB - Vehicular Ad-hoc NETwork (VANET) is a special mobile ad hoc network that composed of facilities such as vehicle nodes and roadside units. Message transfer among vehicle nodes has been a great challenge due to the network's highly variable topology and the selfish nature of vehicle nodes. Thus, it is very necessary to propose a mechanism to improve the cooperation among vehicle nodes to guarantee the effective message transmission. Currently, incentive-based cooperation mechanisms are commonly used to encourage nodes to participate in message transmission. Those mechanisms are based on traditional economics and generally assume that the decision-making behavior of nodes is completely independent. Also, the cooperation of nodes depends on whether the cooperation behavior can obtain the higher utility. But researches in behavioral economics have shown that due to the existence of altruistic reciprocity, the behavior of nodes is affected by not only their utility but also the behavioral motives of other nodes, so as to obtain different results from traditional incentive-based mechanisms. Therefore, the paper introduces the reciprocal altruistic from behavioral economics and proposes the reciprocal altruistic factor to reconstruct the utility function of nodes. The reconstructed utility function reflects the interaction of behavioral motives among nodes, which promotes the node's cooperative behavior. Also, since the Network Formation Game (NFG) is a common mathematical model for studying the interaction and communication links formation among network nodes, hence the paper regards NFG in traditional economics as the research object. A Behavior Economics-based Message Transmission Cooperation Guarantee Mechanism named BMCGM is proposed, which motivates nodes to participate in the message transmission to reduce the transmission delay ratio. The simulation results show that the BMCGM reduces message transmission delay by at least 30.3% compared with the recent representative cooperation transmission mechanism. PMID- 30282938 TI - An Infrastructure-Free Indoor Localization Algorithm for Smartphones. AB - Accurate indoor positioning technology provides location-based service for a variety of applications. However, most existing indoor localization approaches (e.g., Wi-Fi and Bluetooth-based methods) rely heavily on positioning infrastructure, which prevents their large-scale deployment and limits the range at which they are applicable. Here, we proposed an infrastructure-free indoor positioning and tracking approach, termed LiMag, which used ubiquitous magnetic field and ambient lights (e.g., fluorescent, incandescent, and light-emitting diodes (LEDs)) without containing modulated information. We conducted an in-depth study on both the advantages and the challenges in leveraging magnetic field and ambient light intensity for indoor localization. Based on the insights from this study, we established a hybrid observation model that took full advantage of both the magnetic field and ambient light signals. To address the low discernibility of the hybrid observation model, LiMag first generated a single-step fingerprint model by vectorizing consecutive hybrid observations within each step. In order to accurately track users, a lightweight single-step tracking algorithm based on the single-step fingerprints and the particle filter framework was designed. LiMag leveraged the walking information of users and several single-step fingerprints to generate long trajectory fingerprints that exhibited much higher location differentiation ability than the single-step fingerprint. To accelerate particle convergence and eliminate the accumulative error of single-step tracking algorithm, a long trajectory calibration scheme based on long trajectory fingerprints was also introduced. An undirected weighted graph model was constructed to decrease the computational overhead resulting from this long trajectory matching. In addition to typical indoor scenarios including offices, shopping malls and parking lots, we also conducted experiments in more challenging scenarios, including large open-plan areas as well as environments characterized by strong sunlight. Our proposed algorithm achieved a 75th percentile localization accuracy of 1.8 m and 2.2 m, respectively, in the office and shopping mall tested. In conclusion, our LiMag algorithm provided location based service of infrastructure-free with significantly improved localization accuracy and coverage, as well as satisfactory robustness inside complex indoor environments.

AB - Dissimilar Al 3003 and Cu tubular components were successfully brazed without interface cracking using ZrO2 nanomaterials reinforced with Al-19Cu-11Si-2Sn filler. The filler was initially cast using an induction furnace and processed into ring form for brazing. Al-19Cu-11Si-2Sn filler with coarse CuAl2 and Si phases (43 and 20 MUm) were refined to 8 and 4 MUm, respectively, after the addition of 0.1 wt. % ZrO2 and shows significant improvement in the mechanical properties. ZrO2 nanomaterials' induced diffusion controlled growth mechanism is found be the responsible for the refinement of CuAl2 intermetallic and Si particles. The wettability of Al-19Cu-11Si-2Sn-0.1ZrO2 increased to 78.17% on Cu side and 93.19% on the Al side compared from 74.8% and 89.9%, respectively. Increase in the yield strength, ultimate tensile strength, and percentage elongation were noted for the brazed joints. Microstructure of induction brazed joint with 40 kW for 6 seconds using Al-19Cu-11Si-2Sn-0.1ZrO2 filler shows thin interfacial CuAl2 intermetallic compound along the copper side and inter diffusion region along the aluminum side and their respective mechanism is discussed. The tensile strength of the joints increased with increasing the nanomaterials addition and shows a base metal fracture. Analysis of fractured samples shows the effectiveness of ZrO2 reinforced filler in crack propagation through the filler.

AB - The use of self-assembly techniques may open new possibilities in scaling down electronic circuits to their ultimate limits. Deoxyribonucleic acid (DNA) nanotechnology has already demonstrated that it can provide valuable tools for the creation of nanostructures of arbitrary shape, therefore presenting an ideal platform for the development of nanoelectronic circuits. So far, however, the electronic properties of DNA nanostructures are mostly insulating, thus limiting the use of the nanostructures in electronic circuits. Therefore, methods have been investigated that use the DNA nanostructures as templates for the deposition of electrically conducting materials along the DNA strands. The most simple such structure is given by metallic nanowires formed by deposition of metals along the DNA nanostructures. Here, we review the fabrication and the characterization of the electronic properties of nanowires, which were created using these methods.

AB - This paper presents the results of measurements of magnetostrictive properties of Mn0.70Zn0.24Fe2.06O4 ferrite for power applications. Frame-shaped samples were used for measurements to guarantee a uniform magnetizing field and magnetostrictive strain distribution. Magnetostrictive hysteresis loops were measured by semiconductor strain gauges. The results indicate that the magnetostrictive characteristic of Mn0.70Zn0.24Fe2.06O4 ferrite is non-monotonic and magnetostriction changes have opposite signs for higher values of the magnetizing field. PMID- 30282943 TI - Shotgun Lipidomics Revealed Altered Profiles of Serum Lipids in Systemic Lupus Erythematosus Closely Associated with Disease Activity. AB - The pathogenesis of systemic lupus erythematosus (SLE) remains elusive. It appears that serum lipid metabolism is aberrant in SLE patients. Determination of lipid profiles in the serum of SLE patients may provide insights into the underlying mechanism(s) leading to SLE and may discover potential biomarkers for early diagnosis of SLE. This study aimed to identify and quantify the profile of serum lipids in SLE patients (N = 30) with our powerful multi-dimensional mass spectrometry-based shotgun lipidomics platform. Multivariate analysis in the form of partial least squares-discriminate analysis was performed, and the associations between the changed lipids with cytokines and SLE disease activity index (SLEDAI) were analyzed using a multiple regression method. The results of this study indicated that the composition of lipid species including diacyl phosphatidylethanolamine (dPE) (16:0/18:2, 18:0/18:2, 16:0/22:6, 18:0/20:4, and 18:0/22:6), 18:2 lysoPC (LPC), and ceramide (N22:0 and N24:1) was significantly altered in SLE patients with p < 0.05 and variable importance of the projection (VIP) > 1 in partial least squares-discriminate analysis (PLS-DA). There existed significant associations between IL-10, and both 18:0/18:2 and 16:0/22:6 dPE species with p < 0.0001 and predicting 85.7 and 95.8% of the variability of IL-10 levels, respectively. All the altered lipid species could obviously predict IL-10 levels with F (8, 21) = 3.729, p = 0.007, and R2 = 0.766. There was also a significant correlation between the SLEDAI score and 18:0/18:2 dPE (p = 0.031) with explaining 22.6% of the variability of SLEDAI score. Therefore, the panel of changed compositions of dPE and ceramide species may serve as additional biomarkers for early diagnosis and/or prognosis of SLE. PMID- 30282944 TI - A Fast Neighbor Discovery Algorithm in WSNs. AB - With the quick development of Internet of Things (IoT), one of its important supporting technologies, i.e., wireless sensor networks (WSNs), gets much more attention. Neighbor discovery is an indispensable procedure in WSNs. The existing deterministic neighbor discovery algorithms in WSNs ensure that successful discovery can be obtained within a given period of time, but the average discovery delay is long. It is difficult to meet the need for rapid discovery in mobile low duty cycle environments. In addition, with the rapid development of IoT, the node densities of many WSNs greatly increase. In such scenarios, existing neighbor discovery methods fail to satisfy the requirement in terms of discovery latency under the condition of the same energy consumption. This paper proposes a group-based fast neighbor discovery algorithm (GBFA) to address the issues. By carrying neighbor information in beacon packet, the node knows in advance some potential neighbors. It selects more energy efficient potential neighbors and proactively makes nodes wake up to verify whether these potential neighbors are true neighbors, thereby speeding up neighbor discovery, improving energy utilization efficiency and decreasing network communication load. The evaluation results indicate that, compared with other methods, GBFA decreases the average discovery latency up to 10 . 58 % at the same energy budget. PMID- 30282945 TI - The Generated Entropy Monitored by Pyroelectric Sensors. AB - Entropy generation in irreversible processes is a critical issue that affects the failure and aging of electrical, chemical or mechanical systems. The promotion of energy conversion efficiency needs to reduce energy losses, namely to decrease entropy generation. A pyroelectric type of entropy detector is proposed to monitor energy conversion processes in real time. The entropy generation rate can be derived from the induced pyroelectric current, temperature, thermal capacity, pyroelectric coefficient and electrode area. It is profitable to design entropy detectors to maintain a small thermal capacity while pyroelectric sensors minimize geometrical dimensions. Moreover, decreasing the electrode area of the PZT cells could avoid affecting the entropy variation of the measured objects, but the thickness of the cells has to be greatly reduced to promote the temperature variation rate and strengthen the electrical signals. A commercial capacitor with a capacitance of 47 MUF and a maximum endured voltage of 4 V were used to estimate the entropy to act as an indicator of the capacitors' time-to failure. The threshold time was evaluated by using the entropy generation rates at about 7.5 s, 11.25 s, 20 s and 30 s for the applied voltages of 40 V, 35 V, 30 V and 25 V respectively, while using a PZT cell with dimensions of 3 mm square and a thickness of 200 MUm. PMID- 30282946 TI - Fatigue Performance of RC Beams Strengthened with CFRP under Overloads with a Ladder Spectrum. AB - Vehicle overload is detrimental to bridges and traffic safety. This paper presents a study on the fatigue performance of typical reinforced concrete (RC) beams of highway bridges under vehicle overload. A definition method of vehicle overload and a construction method of overload ladder spectrum were first proposed based on traffic data acquisition, statistical analysis and structural calculation of the highway bridges in Guangzhou. A fatigue experimental method was also proposed with the three-ladder vehicle overload spectrum, and the fatigue tests of 15 RC beams strengthened with carbon fiber reinforced polymer (CFRP) under three loading levels were then carried out. The fatigue performance and the failure mechanism of the strengthened beams were presented and discussed, and two fatigue life prediction methods were proposed with the established modified Palmgren-Miner rule and the loading level equivalent method respectively. The results showed that the fatigue performance of the strengthened RC beams was severely degraded under overload ladder spectrum compared with that under constant amplitude cyclic load, and the life prediction methods were proved effective. PMID- 30282947 TI - Gait Symmetry Assessment with a Low Back 3D Accelerometer in Post-Stroke Patients. AB - Gait asymmetry is an important marker of mobility impairment post stroke. This study proposes a new gait symmetry index (GSI) to quantify gait symmetry with one 3D accelerometer at L3 (GSIL3). GSIL3 was evaluated with 16 post stroke patients and nine healthy controls in the Six-Minute-Walk-Test (6-MWT). Discriminative power was evaluated with Wilcoxon test and the effect size (ES) was computed with Cliff's Delta. GSIL3 estimated during the entire 6-MWT and during a short segment straight walk (GSIL3straight) have comparable effect size to one another (ES = 0.89, p < 0.001) and to the symmetry indices derived from feet sensors (|ES| = [0.22, 0.89]). Furthermore, while none of the indices derived from feet sensors showed significant differences between post stroke patients walking with a cane compared to those able to walk without, GSIL3 was able to discriminate between these two groups with a significantly lower value in the group using a cane (ES = 0.70, p = 0.02). In addition, GSIL3 was strongly associated with several symmetry indices measured by feet sensors during the straight walking cycles (Spearman correlation: |rho| = [0.82, 0.88], p < 0.05). The proposed index can be a reliable and cost-efficient post stroke gait symmetry assessment with implications for research and clinical practice. PMID- 30282949 TI - 2'-O-Methylation of Ribosomal RNA: Towards an Epitranscriptomic Control of Translation? AB - Ribosomal RNA (rRNA) undergoes post-transcriptional modification of over 200 nucleotides, predominantly 2'-O-methylation (2'-O-Me). 2'-O-Methylation protects RNA from hydrolysis and modifies RNA strand flexibility but does not contribute to Watson-Crick base pairing. The contribution of 2'-O-Me to the translational capacity of ribosomes has been established. Yet, how 2'-O-Me participates in ribosome biogenesis and ribosome functioning remains unclear. The development of 2'-O-Me quantitative mapping methods has contributed to the demonstration that these modifications are not constitutive but rather provide heterogeneity to the ribosomal population. Moreover, recent advances in ribosome structure analysis and in vitro translation assays have proven, for the first time, that 2'-O-Me contributes to regulating protein synthesis. This review highlights the recent data exploring the impact of 2'-O-Me on ribosome structure and function, and the emerging idea that the rRNA epitranscriptome is involved in translational control. PMID- 30282950 TI - Regional Absorption of Fimasartan in the Gastrointestinal Tract by an Improved in situ Absorption Method in Rats. AB - The aim of the present study was to assess the regional absorption of fimasartan by an improved in situ absorption method in comparison with the conventional in situ single-pass perfusion method in rats. After each gastrointestinal segment of interest was identified, fimasartan was injected into the starting point of each segment and the unabsorbed fimasartan was discharged from the end point of the segment. Blood samples were collected from the jugular vein to evaluate the systemic absorption of the drug. The relative fraction absorbed (Fabs,relative) values in the specific gastrointestinal region calculated based on the area under the curve (AUC) values obtained after the injection of fimasartan into the gastrointestinal segment were 8.2% +/- 3.2%, 23.0% +/- 12.1%, 49.7% +/- 11.5%, and 19.1% +/- 11.9% for the stomach, duodenum, small intestine, and large intestine, respectively, which were comparable with those determined by the conventional in situ single-pass perfusion. By applying the fraction of the dose available at each gastrointestinal segment following the oral administration, the actual fraction absorbed (F'abs) values at each gastrointestinal segment were estimated at 10.9% for the stomach, 27.1% for the duodenum, 40.7% for the small intestine, and 5.4% for the large intestine, which added up to the gastrointestinal bioavailability (FX.FG) of 84.1%. The present method holds great promise to assess the regional absorption of a drug and aid to design new drug formulations. PMID- 30282951 TI - A Novel Adaptive Signal Processing Method Based on Enhanced Empirical Wavelet Transform Technology. AB - Empirical wavelet transform (EWT) is a novel adaptive signal decomposition method, whose main shortcoming is the fact that Fourier segmentation is strongly dependent on the local maxima of the amplitudes of the Fourier spectrum. An enhanced empirical wavelet transform (MSCEWT) based on maximum-minimum length curve method is proposed to realize fault diagnosis of motor bearings. The maximum-minimum length curve method transforms the original vibration signal spectrum to scale space in order to obtain a set of minimum length curves, and find the maximum length curve value in the set of the minimum length curve values for obtaining the number of the spectrum decomposition intervals. The MSCEWT method is used to decompose the vibration signal into a series of intrinsic mode functions (IMFs), which are processed by Hilbert transform. Then the frequency of each component is extracted by power spectrum and compared with the theoretical value of motor bearing fault feature frequency in order to determine and obtain fault diagnosis result. In order to verify the effectiveness of the MSCEWT method for fault diagnosis, the actual motor bearing vibration signals are selected and the empirical mode decomposition (EMD) and ensemble empirical mode decomposition (EEMD) methods are selected for comparative analysis in here. The results show that the maximum-minimum length curve method can enhance EWT method and the MSCEWT method can solve the shortcomings of the Fourier spectrum segmentation and can effectively decompose the bearing vibration signal for obtaining less number of intrinsic mode function (IMF) components than the EMD and EEMD methods. It can effectively extract the fault feature frequency of the motor bearing and realize fault diagnosis. Therefore, the study provides a new method for fault diagnosis of rotating machinery.

AB - Topological indices are numerical parameters used to study the physical and chemical properties of compounds. In quantitative structure-activity relationship QSARs, topological indices correlate the biological activity of compounds with their physical properties like boiling point, stability, melting point, distortion, and strain energy etc. In this paper, we determined the M-polynomials of the crystallographic structure of the molecules Cu2O and TiF2 [p,q,r]. Then we derived closed formulas for some well-known topological indices using calculus. In the end, we used Maple 15 to plot surfaces associated with the topological indices of Cu2O and TiF2 [p,q,r]. PMID- 30282952 TI - Stunting, Beyond Acute Diarrhoea: Giardia Duodenalis, in Cambodia. AB - BACKGROUND: The adverse outcomes of malnutrition on the development of a child are well acknowledged as are the broad variety of contextual factors that may impact child nutritional status. Adequate nutrient intake and the adoption of appropriate water, sanitation and hygiene measures are largely documented for their positive influence on health. Improved sanitation and protection from human feces can significantly lower the incidence of diarrhea and environmental enteropathy. However, the impact of excessive exposure to animal feces on child health is less well documented. OBJECTIVES: This study tests the hypothesis that there is a positive association between exposure to animal feces, morbidity and anthropometric outcomes in children under 5 years of age, in Cambodia. It aims to improve insights that can contribute to discerning high-impact policies that promote children can develop to their full potential. METHODS: Data for this study was drawn from the third follow-up round of the MyHealth project cohort study that is conducted in six districts of three Cambodian provinces (Phnom Penh, Kratie and Ratanak Kiri). The analysis included a sample of 639 children under 5 years of age. RESULTS: The presence of livestock and more particularly, pigs near the main household dwelling was found a risk factor associated with Giardia duodenalis infection (23%). Giardia duodenalis infection was found to be a protective factor for acute diarrhea, yet, associated with stunting in the univariate model. CONCLUSIONS: Preventive measures that protect from extensive exposure to animal feces may be most effective to prevent infection with Giardia duodenalis and consequent stunting, thereby improving the potential for a healthy development in young Cambodian children. The results support the need for cross sector policy measures that reinforce comprehensive early childhood interventions towards improving nutritional status as part of a wider set of child welfare and development measures.

AB - Four copolymers (P(tCz (tris(4-carbazoyl-9-ylphenyl)amine)-co-bTP (2,2' bithiophene)), P(tCz-co-CPDT (4H-cyclopenta[2,1-b:3,4-b']dithiophene)), P(tCz-co DTC (3,6-di(2-thienyl)carbazole)), and P(tCz-co-CPDTK (cyclopentadithiophene ketone))) are deposited on indium tin oxide (ITO) surfaces using electrochemical polymerization. Spectroelectrochemical properties of copolymer electrodes reveal that the colors of P(tCz-co-bTP) film are pinkish-orange, light olive green, light grayish blue, and dark blue at 0.0, 0.8, 1.2, and 1.6 V, respectively, whereas the color variations of P(tCz-co-CPDTK) film are light yellow, yellow, and blue at 0.0 V, 0.8 V, and 1.5 V, respectively. The DeltaT of P(tCz-co-bTP), P(tCz-co-CPDT), P(tCz-co-DTC), and P(tCz-co-CPDTK) films are estimated to be 43.0% at 967 nm, 28.7% at 864 nm, 43.6% at 870 nm, and 24.5% at 984 nm, respectively. Five electrochromic devices (ECDs) are assembled using the tCz based homopolymer and copolymers as coloring electrodes, and poly(2,2-dimethyl 3,4-propylenedioxythiophene) (PProDOT-Me2) as the complementary electrode. P(tCz co-DTC)/PProDOT-Me2 ECD reveals high transmittance change (45.9% at 624 nm), P(tCz-co-CPDTK)/PProDOT-Me2 ECD shows high eta (513.0 cm2 C-1 at 582 nm), and P(tCz-co-bTP)/PProDOT-Me2 ECD presents short switching time (less than 0.4 s) at 628 nm. Moreover, these ECDs show satisfactory redox stability and open circuit stability. PMID- 30282948 TI - Protein Quality Control in the Endoplasmic Reticulum and Cancer. AB - The endoplasmic reticulum (ER) is an essential compartment of the biosynthesis, folding, assembly, and trafficking of secretory and transmembrane proteins, and consequently, eukaryotic cells possess specialized machineries to ensure that the ER enables the proteins to acquire adequate folding and maturation for maintaining protein homeostasis, a process which is termed proteostasis. However, a large variety of physiological and pathological perturbations lead to the accumulation of misfolded proteins in the ER, which is referred to as ER stress. To resolve ER stress and restore proteostasis, cells have evolutionary conserved protein quality-control machineries of the ER, consisting of the unfolded protein response (UPR) of the ER, ER-associated degradation (ERAD), and autophagy. Furthermore, protein quality-control machineries of the ER play pivotal roles in the control of differentiation, progression of cell cycle, inflammation, immunity, and aging. Therefore, severe and non-resolvable ER stress is closely associated with tumor development, aggressiveness, and response to therapies for cancer. In this review, we highlight current knowledge in the molecular understanding and physiological relevance of protein quality control of the ER and discuss new insights into how protein quality control of the ER is implicated in the pathogenesis of cancer, which could contribute to therapeutic intervention in cancer. PMID- 30282955 TI - Current and Emerging Reconstituted HDL-apoA-I and HDL-apoE Approaches to Treat Atherosclerosis. AB - Atherosclerosis affects millions of people worldwide. However, the wide variety of limitations in the current therapeutic options leaves much to be desired in future lipid-lowering therapies. For example, although statins, which are the first-line treatment for coronary heart disease (CHD), reduce the risk of cardiovascular events in a large percentage of patients, they lead to optimal levels of low density lipoprotein-cholesterol (LDL-C) in only about one-third of patients. A new promising research direction against atherosclerosis aims to improve lipoprotein metabolism. Novel therapeutic approaches are being developed to increase the levels of functional high density lipoprotein (HDL) particles. This review aims to highlight the atheroprotective potential of the in vitro synthesized reconstituted HDL particles containing apolipoprotein E (apoE) as their sole apolipoprotein component (rHDL-apoE). For this purpose, we provide: (1) a summary of the atheroprotective properties of native plasma HDL and its apolipoprotein components, apolipoprotein A-I (apoA-I) and apoE; (2) an overview of the anti-atherogenic functions of rHDL-apoA-I and apoA-I-containing HDL, i.e., natural HDL isolated from transgenic Apoa1-/- * Apoe-/- mice overexpressing human apoA-I (HDL-apoA-I); and (3) the latest developments and therapeutic potential of HDL-apoE and rHDL-apoE. Novel rHDL formulations containing apoE could possibly present enhanced biological functions, leading to improved therapeutic efficacy against atherosclerosis. PMID- 30282956 TI - Derivation and Validation of Machine Learning Approaches to Predict Acute Kidney Injury after Cardiac Surgery. AB - Machine learning approaches were introduced for better or comparable predictive ability than statistical analysis to predict postoperative outcomes. We sought to compare the performance of machine learning approaches with that of logistic regression analysis to predict acute kidney injury after cardiac surgery. We retrospectively reviewed 2010 patients who underwent open heart surgery and thoracic aortic surgery. Baseline medical condition, intraoperative anesthesia, and surgery-related data were obtained. The primary outcome was postoperative acute kidney injury (AKI) defined according to the Kidney Disease Improving Global Outcomes criteria. The following machine learning techniques were used: decision tree, random forest, extreme gradient boosting, support vector machine, neural network classifier, and deep learning. The performance of these techniques was compared with that of logistic regression analysis regarding the area under the receiver-operating characteristic curve (AUC). During the first postoperative week, AKI occurred in 770 patients (38.3%). The best performance regarding AUC was achieved by the gradient boosting machine to predict the AKI of all stages (0.78, 95% confidence interval (CI) 0.75-0.80) or stage 2 or 3 AKI. The AUC of logistic regression analysis was 0.69 (95% CI 0.66-0.72). Decision tree, random forest, and support vector machine showed similar performance to logistic regression. In our comprehensive comparison of machine learning approaches with logistic regression analysis, gradient boosting technique showed the best performance with the highest AUC and lower error rate. We developed an Internet based risk estimator which could be used for real-time processing of patient data to estimate the risk of AKI at the end of surgery. PMID- 30282958 TI - A Serological Survey on Swine Brucellosis Using Standard Procedures, Dot Blot, and Western Blot in Finisher Pigs in Central-North Italy. AB - In recent years, Brucella suis has been sporadically reported in Italy in domestic and wild swine. Since standard serological tests can determine false positive results, the development of alternative tests with improved sensitivity and specificity is rather essential. We analyzed 1212 sera collected at slaughterhouse from healthy pigs belonging to 62 farms of North-Central Italy. Sera were tested by Rose Bengal Test, Complement Fixation Test, and subsequently by a Dot Blot (DB) and Western Blot assays (WB). Only one serum resulted positive to all tests, indicating that swine brucellosis has a very limited spread. DB and WB could represent a support to the available serological tests; however, further studies to validate these tests are needed. In the presence of reemerging diseases, a prompt and continuous monitoring design is necessary to acquire epidemiological information for the subsequent application of specific health emergency plans.

Therefore, we conducted dry-to-wet lab research approaches to assess the correlation of type 1 DM (T1DM) and type 2 DM (T2DM) with KOA among all age and genders of Taiwanese population. The strength of association (odds ratio: OR) was analyzed using a phenome-wide association study portal. Populations of 37,353 T1DM and 1,218,254 T2DM were included. We observed a significant association of KOA with T1DM (OR: 1.40 (1.33 1.47), p< 0.0001) and T2DM (OR: 2.75 (2.72-2.78), p< 0.0001). The association between T1DM and KOA among the obese (OR: 0.99 (0.54-1.67), p = 0.0477) was insignificant compared to the non-obese (OR: 1.40 (1.33-1.48), p < 0.0001). Interestingly, a higher association between T2DM and KOA among non-obese persons (OR: 2.75, (2.72-2.79), p < 0.0001) compared to the obese (OR: 1.71 (1.55-1.89), p < 0.0001) was noted. Further, histopathologic and Western blot studies of diabetic mice knee joints revealed enhanced carboxymethyl lysine (advanced glycation end product), matrix metalloproteinase-1, and reduced cartilage specific proteins, including type II collagen (Col II), SOX9, and aggrecan (AGN), indicating deteriorated articular cartilage and proteoglycans. Results indicate that DM is strongly associated with KOA, and obesity may not be a confounding factor.

AB - Bioassays and molecular diagnostics are routinely used for the monitoring of malaria vector populations to support insecticide resistance management (IRM), guiding operational decisions on which insecticides ought to be used for effective vector control. Previously developed TaqMan assays were optimised to distinguish the wild-type L1014 from the knockdown resistance (kdr) point mutations 1014F and 1014S (triplex reaction), and the N1575 wild-type from the point mutation 1575Y (duplex reaction). Subsequently, artificial pools of Anopheles gambiae (An. gambiae) specimens with known genotypes of L1014F, L1014S, and N1575Y were created, nucleic acids were extracted, and kdr mutations were detected. These data were then used to define a linear regression model that predicts the allelic frequency within a pool of mosquitoes as a function of the measured DeltaCt values (Ct mutant - Ct wild type probe). Polynomial regression models showed r2 values of >0.99 (p < 0.05). The method was validated with populations of variable allelic frequencies, and found to be precise (1.66 2.99%), accurate (3.3-5.9%), and able to detect a single heterozygous mosquito mixed with 9 wild type individuals in a pool of 10. Its pilot application in field-caught samples showed minimal differences from individual genotyping (0.36 4.0%). It allowed the first detection of the super-kdr mutation N1575Y in An. gambiae from Mali. Using pools instead of individuals allows for more efficient resistance allele screening, facilitating IRM. PMID- 30282960 TI - Combining Microbubble Contrast Agent with Pulsed-Laser Irradiation for Transdermal Drug Delivery. AB - The optodynamic process of laser-induced microbubble (MB) cavitation in liquids is utilized in various medical applications. However, how incident laser radiation interacts with MBs as an ultrasound contrast agent is rarely estimated when the liquid already contains stable MBs. The present study investigated the efficacy of the laser-mediated cavitation of albumin-shelled MBs in enhancing transdermal drug delivery. Different types and conditions of laser-mediated inertial cavitation of MBs were first evaluated. A CO2 fractional pulsed laser was selected for combining with MBs in the in vitro and in vivo experiments. The in vitro skin penetration by beta-arbutin after 2 h was 2 times greater in the group combining a laser with MBs than in the control group. In small-animal experiments, the whitening effect on the skin of C57BL/6J mice in the group combining a laser with MBs on the skin plus penetrating beta-arbutin increased (significantly) by 48.0% at day 11 and 50.0% at day 14, and then tended to stabilize for the remainder of the 20-day experimental period. The present results indicate that combining a CO2 laser with albumin-shelled MBs can increase skin permeability so as to enhance the delivery of beta-arbutin to inhibit melanogenesis in mice without damaging the skin. PMID- 30282961 TI - Development of a Multiwavelength Visible-Range-Supported Opto-Ultrasound Instrument Using a Light-Emitting Diode and Ultrasound Transducer. AB - A new multiwavelength visible-range-supported opto-ultrasound instrument using a light-emitting diode and ultrasound transducer was developed in order to produce multiwavelength visible light with minimized color aberration errors, and detect ultrasound signals emitted from the target. In the instrument, the developed optical systems can provide multiwavelength optical transmission with low optical aberration within 10-cm ranges that are reasonably flat in the modulation transfer function at spatial frequencies of 20 and 40 lp/mm, except at the end of the diagonal edge of the samples. To assess the instrument capability, we performed pulse-echo responses with Thunnus obesus eye samples. Focused red, green, blue and white light rays from an integrated red, green and blue LED source were produced, and echo signal amplitudes of 33.53, 34.92, 38.74 and 82.54 mV, respectively, were detected from the Thunnus obesus eye samples by a 10-MHz focused ultrasound transducer. The center frequencies of the echo signal when producing red, green, blue and white LED light in the instrument were 9.02, 9.05, 9.21 and 8.81 MHz, respectively. From these tests, we verify that this instrument can combine red, green and blue LED light to cover different wavelengths in the visible-light range and detect reasonable echo amplitudes from the samples.

Although the combination of polychemotherapy and surgical excision increased the survival rates up to 60%, the prognosis remains poor for most patients with metastatic or recurrent osteosarcoma. However, the exact pathogenic mechanism and pivotal elements regulating tumor invasion and metastasis are largely unknown. Circular RNAs (circRNAs) are novel endogenous non coding RNA (ncRNA) molecules that generate the cyclic structure from back splicing. An increasing number of studies show that circRNAs can regulate transcriptional or posttranscriptional gene expression by acting as microRNA (miRNA) sponges and are involved in regulation of many important biological processes. The deregulation of some circRNAs was demonstrated in osteosarcoma. Furthermore, some circRNAs were identified to play essential roles in osteosarcoma occurrence, invasion, and metastasis. This review summarizes the regulatory effect of circRNAs in the occurrence and development of osteosarcoma, concentrating on deregulation, regulatory mechanisms, and functions of circRNAs and their potential value as biomarkers and therapy. PMID- 30282963 TI - Treatment of Renal Fungal Ball with Fluconazole Instillation Through a Nephrostomy Tube: Case Report and Literature Review. AB - BACKGROUND Urinary tract candida infection can be due either to hematogenous dissemination of the organism or a retrograde infection. In debilitated or immunosuppressed septic patients, who have upper urinary tract obstruction with renal filling defect, fungal infection should be considered. We report on a patient with sepsis and renal fungal ball who was treated with percutaneous nephrostomy and intravenous antifungal agent, but the patient did not respond so instillation of fluconazole through nephrostomy was given. CASE REPORT A 60-year old male patient with a known case of diabetes mellitus with refractory urine retention underwent transurethral resection of the prostate. Postoperatively, the patient developed recurrent high-grade fever with left loin pain, and elevated septic parameters; urine and blood culture were positive for Candida albicans. Computed tomography urography showed left hydronephrosis with filling defect in the left renal pelvis with suspected renal fungal ball. Left percutaneous nephrostomy was performed and intravenous fluconazole started but the fever did not subside, therefore, the treatment was changed to anidulafungin. The patient improved but urine from both the bladder and the nephrostomy remained positive for candida. Instillation of fluconazole at 300 mg in 500 mL normal saline was applied through the nephrostomy tube over 12 hours at 40 mL/hour for 7 days. CONCLUSIONS Renal fungal ball is rare but can be serious, especially in immunocompromised patients. Management options for renal fungal ball include intravenous antifungal agents and percutaneous nephrostomy with antifungal instillation of antifungal agents. The objective of this case report was to document treatment success with the use of fluconazole instillation through a nephrostomy tube. PMID- 30282964 TI - Transient receptor potential channel 6 knockdown prevents apoptosis of renal tubular epithelial cells upon oxidative stress via autophagy activation. AB - Reactive oxygen species (ROS) are generated under various pathological conditions such as renal ischemia/reperfusion (I/R) injury and provoke damage to multiple cellular organelles and processes. Overproduction of ROS causes oxidative stress and contributes to damages of renal proximal tubular cells (PTC), which are the main cause of the pathogenesis of renal I/R injury. Autophagy is a dynamic process that removes long-lived proteins and damaged organelles via lysosome mediated degradation, which has an antioxidant effect that relieves oxidative stress. The canonical transient receptor potential channel 6 (TRPC6), a nonselective cation channel that allows passage of Ca2+, plays an important role in renal disease. Yet, the relationship between TRPC6 and autophagy, as well as their functions in renal oxidative stress injury, remains unclear. In this study, we found that oxidative stress triggered TRPC6-dependent Ca2+ influx in PTC to inhibit autophagy, thereby rendering cells more susceptible to death. We also demonstrated that TRPC6 knockout (TRPC6-/-) or inhibition by SAR7334, a TRPC6 selective inhibitor, increased autophagic flux and mitigated oxidative stress induced apoptosis of PTC. The protective effects of TRPC6 ablation were prevented by autophagy inhibitors Chloroquine and Bafilomycin A1. Moreover, this study also shows that TRPC6 blockage promotes autophagic flux via inhibiting the PI3K/Akt/mTOR and ERK1/2 signaling pathways. This is the first evidence showing that TRPC6-mediated Ca2+ influx plays a novel role in suppressing cytoprotective autophagy triggered by oxidative stress in PTC, and it may become a novel therapeutic target for the treatment of renal oxidative stress injury in the future. PMID- 30282965 TI - Reduction of HIP2 expression causes motor function impairment and increased vulnerability to dopaminergic degeneration in Parkinson's disease models. AB - Huntingtin interaction protein 2 (HIP2) is an E2 ubiquitin-conjugating enzyme associated with neurodegenerative diseases, and HIP2 mRNA has been implicated as a potential blood biomarker for Parkinson's disease (PD). However, it is unclear whether the alteration of HIP2 expression may contribute to the development of PD, and whether the change of HIP2 in blood could reflect its expression in the brain or motor functions in PD patients. In this study, we established a mouse line with HIP2 haploinsufficiency. The reduction of the HIP2 expression led to spontaneous motor function impairment and dopaminergic neuronal loss. Furthermore, HIP2 haploinsufficiency increased the susceptibility of mice to 6 hydroxydopamine (6-OHDA) and caused severe loss of dopaminergic neurons. Interestingly, in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model for PD, we observed concurrent, highly correlated decrease of HIP2 expression in the brain and in the blood. Using blood samples from more than 300 patients, we validated the decreased HIP2 mRNA in PD patients, including de novo patients. Finally, in a 1-year, 20-patient study, we observed reversed blood HIP2 mRNA levels accompanying improved motor and overall daily functions in 75% of the PD patients with instructed Tai Chi training. Therefore, our in vivo studies have indicated HIP2 insufficiency as a contributing factor for PD, and functionally validated blood HIP2 as a useful and reversible biomarker for PD. PMID- 30282966 TI - Novel engineered, membrane-localized variants of vascular endothelial growth factor (VEGF) protect retinal ganglion cells: a proof-of-concept study. AB - Endogenous vascular endothelial growth factor (VEGF-A) can protect retinal ganglion cells (RGC) from stress-induced cell death in ocular hypertensive glaucoma. To exploit the neuroprotective function of VEGF-A for therapeutic application in ocular disorders such as glaucoma while minimizing unwanted vascular side effects, we engineered two novel VEGF variants, eVEGF-38 and eVEGF 53. These variants of the diffusible VEGF-A isoform VEGF121 are expressed as dimeric concatamers and remain tethered to the cell membrane, thus restricting the effects of the engineered VEGF to the cells expressing the protein. For comparison, we tested a Myc-tagged version of VEGF189, an isoform that binds tightly to the extracellular matrix and heparan sulfate proteoglycans at the cell surface, supporting only autocrine and localized juxtacrine signaling. In human retinal endothelial cells (hREC), expression of eVEGF-38, eVEGF-53, or VEGF189 increased VEGFR2 phosphorylation without increasing expression of pro inflammatory markers, relative to VEGF165 protein and vector controls. AAV2 mediated transduction of eVEGF-38, eVEGF-53, or VEGF189 into primary mouse RGC promoted synaptogenesis and increased the average total length of neurites and axons per RGC by ~ 12-fold, an increase that was mediated by VEGFR2 and PI3K/AKT signaling. Expression of eVEGF-38 in primary RGC enhanced expression of genes associated with neuritogenesis, axon outgrowth, axon guidance, and cell survival. Transduction of primary RGC with any of the membrane-associated VEGF constructs increased survival both under normal culture conditions and in the presence of the cytotoxic chemicals H2O2 (via VEGFR2/PI3K/AKT signaling) and N-methyl-D aspartate (via reduced Ca2+ influx). Moreover, RGC number was increased in mouse embryonic stem cell-derived retinal organoid cultures transduced with the eVEGF 53 construct. The novel, engineered VEGF variants eVEGF-38 and eVEGF-53 show promise as potential therapeutics for retinal RGC neuroprotection when delivered using a gene therapy approach.

PMID- 30282967 TI - Hydroxypropyl-beta and -gamma cyclodextrins rescue cholesterol accumulation in Niemann-Pick C1 mutant cell via lysosome-associated membrane protein 1. AB - Niemann-Pick type C (NPC) disease is a fatal hereditary neurodegenerative disorder characterized by a massive accumulation of cholesterol in lysosomes and late endosomes due to a defect in intracellular cholesterol trafficking. Dysfunction in intracellular cholesterol trafficking is responsible for about 50 rare inherited lysosomal storage disorders including NPC. The lysosomal proteins NPC1 and NPC2 play a crucial role in trafficking of cholesterol from late endosomes and lysosomes to other cellular compartments. However, the detailed mechanisms of cholesterol trafficking at the late endosomes/lysosomes (LE/LY) are poorly understood. Studies showed that 2-hydroxypropyl-beta-cyclodextrin (HPbetaCD) alleviates the cholesterol accumulation defect in animal model and has been approved for a phase 2b/3 clinical trial for NPC. HPbetaCD is known to bind cholesterol; however, the mechanisms how HPbetaCD mediates the exit of cholesterol from the LE/LY compartments are still unknown. Further, another cyclodextrin (CD) derivative, 2-hydroxypropyl-gamma-cyclodextrin (HPgammaCD), was shown to reduce intracellular cholesterol accumulation in NPC patient cells and NPC mice model. Herein, we identified a number of candidate proteins differentially expressed in NPC patient-derived cells compared to cells derived from a healthy donor using a proteomic approach. Interestingly, both HPbetaCD and HPgammaCD treatments modulated the expression of most of these NPC-specific proteins. Data showed that treatment with both CDs induces the expression of the lysosome-associated membrane protein 1 (LAMP-1) in NPC patient-derived cells. Remarkably, LAMP-1 overexpression in HeLa cells rescued U18666A-induced cholesterol accumulation suggesting a role of LAMP-1 in cholesterol trafficking. We propose that HPbetaCD and HPgammaCD facilitate cholesterol export from the LE/LY compartments via the LAMP-1 protein, which may play a crucial role in cholesterol trafficking at the LE/LY compartments when there is no functional NPC1 protein. Together, this study uncovers new cellular mechanisms for cholesterol trafficking, which will contribute to development of novel therapeutic approaches for lysosomal storage diseases. PMID- 30282969 TI - BMSCs pre-treatment ameliorates inflammation-related tissue destruction in LPS induced rat DIC model. AB - This study aimed to investigate the effect of bone marrow-derived mesenchymal stem cells (BMSCs) on disseminated intravascular coagulation (DIC) model rats and to further explore the underlying mechanism. A rat model of lipopolysaccharide (LPS)-induced DIC was successfully established, as indicated by impaired plasma hemostatic parameters and damaged organ functions in rats. Importantly, pre treatment with rat allogeneic BMSCs before LPS injection significantly alleviated systemic intravascular coagulation, reduced plasma levels of organ dysfunction indicators and pro-inflammatory cytokines, suppressed fibrin microthrombi formation, ameliorated liver, heart, and renal injuries, and increased 24-hour survival rates in LPS-induced DIC rats. The protection of BMSCs against DIC was in a moderately dose-dependent manner. Further investigation revealed that BMSCs co-cultured with peripheral blood mononuclear cells (PBMCs) significantly inhibited the LPS-stimulated PBMCs proliferation and the release of pro inflammatory cytokines from PBMCs. Of note, upregulation of immunosuppressive factors including indoleamine 2,3-dioxygenase and interleukin-10, which was induced by interferon-gamma, contributed to BMSCs-mediated inhibition of LPS stimulated PBMCs proliferation. These effects do not depend on the direct cell cell contact. In conclusion, BMSCs pre-treatment ameliorates inflammation-related tissue destruction in LPS-induced DIC model rats. The protection of BMSCs may be attributed to their anti-inflammatory and immunomodulatory properties, which render BMSCs a promising source for stem cell-based therapeutic approaches in inflammation-related DIC. PMID- 30282971 TI - High-content ductile coherent nanoprecipitates achieve ultrastrong high-entropy alloys. AB - Precipitation-hardening high-entropy alloys (PH-HEAs) with good strength ductility balances are a promising candidate for advanced structural applications. However, current HEAs emphasize near-equiatomic initial compositions, which limit the increase of intermetallic precipitates that are closely related to the alloy strength. Here we present a strategy to design ultrastrong HEAs with high-content nanoprecipitates by phase separation, which can generate a near-equiatomic matrix in situ while forming strengthening phases, producing a PH-HEA regardless of the initial atomic ratio. Accordingly, we develop a non-equiatomic alloy that utilizes spinodal decomposition to create a low-misfit coherent nanostructure combining a near-equiatomic disordered face centered-cubic (FCC) matrix with high-content ductile Ni3Al-type ordered nanoprecipitates. We find that this spinodal order-disorder nanostructure contributes to a strength increase of ~1.5 GPa (>560%) relative to the HEA without precipitation, achieving one of the highest tensile strength (1.9 GPa) among all bulk HEAs reported previously while retaining good ductility (>9%). PMID- 30282972 TI - LncRNA-MEG3 inhibits activation of hepatic stellate cells through SMO protein and miR-212. AB - Activation of hepatic stellate cells (HSCs), a pivotal event in liver fibrosis, is considered as an epithelial-mesenchymal transition (EMT) process. Deregulation of long noncoding RNAs (lncRNAs) has been reported to be involved in a series of human diseases. LncRNA-maternally expressed gene 3 (MEG3) functions as a tumor suppressor in cancers and has been shown to play a vital role in EMT process. However, the biological role of MEG3 in liver fibrosis is largely unknown. In this study, MEG3 was reduced in vivo and in vitro during liver fibrosis. Restoring of MEG3 expression led to the suppression of liver fibrosis, with a reduction in alpha-SMA and type I collagen. Notably, MEG3 overexpression inhibited HSC activation through EMT, associated with an increase in epithelial markers and a reduction in mesenchymal markers. Further studies showed that Hedgehog (Hh) pathway-mediated EMT process was involved in the effects of MEG3 on HSC activation. Smoothened (SMO) is a member of Hh pathway. Using bioinformatic analysis, an interaction between MEG3 and SMO protein was predicted. This interaction was confirmed by the results of RNA immunoprecipitation and deletion mapping analysis. Furthermore, MEG3 was confirmed as a target of microRNA-212 (miR-212). miR-212 was partly responsible for the effects of MEG3 on EMT process. Interestingly, MEG3 was also reduced in chronic hepatitis B (CHB) patients with liver fibrosis when compared with healthy controls. MEG3 negatively correlated with fibrosis stage in CHB patients. In conclusion, we demonstrate that MEG3 inhibits Hh-mediated EMT process in liver fibrosis via SMO protein and miR-212. PMID- 30282970 TI - Diagnosis and treatment of schizotypal personality disorder: evidence from a systematic review. AB - The main objective of this review was to evaluate studies on the diagnosis, treatment, and course of schizotypal personality disorder and to provide a clinical guidance on the basis of that evaluation. A systematic search in the PubMed/MEDLINE databases was conducted. Two independent reviewers extracted and assessed the quality of the data. A total of 54 studies were eligible for inclusion: 18 were on diagnostic instruments; 22, on pharmacological treatment; 3, on psychotherapy; and 13, on the longitudinal course of the disease. We identified several suitable and reliable questionnaires for screening (PDQ-4+ and SPQ) and diagnosing (SIDP, SIDP-R, and SCID-II) schizotypal personality disorder. Second-generation antipsychotics (mainly risperidone) were the most often studied drug class and were described as beneficial. Studies on the longitudinal course described a moderate remission rate and possible conversion rates to other schizophrenia spectrum disorders. Because of the heterogeneity of the studies and the small sample sizes, it is not yet possible to make evidence-based recommendations for treatment. This is a systematic evaluation of diagnostic instruments and treatment studies in schizotypal personality disorder. We conclude that there is currently only limited evidence on which to base treatment decisions in this disorder. Larger interventional trials are needed to provide the data for evidence-based recommendations. PMID- 30282973 TI - Exosomal 15-LO2 mediates hypoxia-induced pulmonary artery hypertension in vivo and in vitro. AB - Our previous studies have shown that 15-LO2/15-HETE induced by hypoxia played an important role in pulmonary arterial hypertension (PH). However, the transportations of 15-LO2/15-HETE among the cells remain elusive. In this study, we investigated the specific involvement of 15-LO2-containing exosomes in the overproliferation of pulmonary artery endothelial cells (PAECs) induced by hypoxia and the underlying mechanism. In vitro, 15-LO2 was abundantly expressed and enriched in exosomes secreted from hypoxic PAECs, which subsequently activated the STAT3 signaling pathway, resulting in a robust increase in PAECs proliferation. In vivo treatment with the exosomes inhibitor GW4869 protected the pulmonary vascular homeostasis from dysfunctional and abnormal remodeling. Moreover, 15-LO2 was ubiquitinated under hypoxia, and further inhibition of the ubiquitin-proteasome system significantly suppressed PAECs proliferation, suggesting that ubiquitination of 15-LO2 may contribute to its sorting into exosomes. Overall, these findings indicate a previously unrecognized effect of exosomes and the cargo 15-LO2 in pulmonary vascular homeostasis on the pathogenesis of PH. PMID- 30282974 TI - The use of natural media amendments to produce kale enhanced with functional lipids in controlled environment production system. AB - Diets high in vegetable consumption is highly correlated with reduced risk of developing common lifestyle related diseases. We investigated the effects of three natural growth media amendments [potassium humate, dry vermicast, volcanic minerals or Promix alone (Control)] in enhancing the accumulation of functional lipids in greenhouse grown kale. Functional lipids (n9, n6, n3 fatty acids, diglycerides, galactolipids and phytosterols) were assessed using either gas chromatography/mass spectrometry (GC/MS) or ultra-high performance liquid chromatography-high resolution tandem mass spectrometry (UHPLC-HRMS/MS). The results showed volcanic minerals and dry vermicast were the most successful in enhancing the accumulation of functional lipids in kale. For example, dry vermicast enhanced the accumulation of total C18:1n9 and C16:3n3 fatty acids, while total C18:2n6 fatty acid accumulation was enhanced by volcanic minerals. In conclusion, natural growing medium amendments are remarkably effective in modulating the accumulation of functional lipids in kale grown under controlled environment conditions. This could be a useful strategy for functional foods production in control environment production systems. Increase access to kale with enhanced functional lipids could aid in increase consumption of these health promotive compounds in the diet with potential implications in population health. PMID- 30282976 TI - The effect of pulsed current on the shear deformation behavior of Ti-6Al-4V alloy. AB - Pulse current-assisted forming is a new technology to improve the plastic deformability of titanium alloy. In this work, Shearing tests of Ti-6Al-4V alloy were conducted using hat-shaped specimens under pulsed current (electroplastic shearing) and constant temperature (isothermal shearing). The actual deformation in shear zone of electroplastic shearing was larger than that of isothermal shearing. The shear load is also decreased by the pulsed current. Microstructure variation in the shear zone was investigated by scanning electron microscopy. An evident straight shear band was observed in the electroplastic shearing specimens. The deformation model of shear zone was established. Intracrystalline deformation was markedly easier for the grains with the pulsed current and induced larger deformation of the grains along the shear direction. Microcracks were observed in the shear zone of isothermal shearing, but none were found in the shear zone of electroplastic shearing. Evident crack healing was found in the crack tip of the shear zone of electroplastic shearing. PMID- 30282975 TI - Patients with Chronic Obstructive Pulmonary Disease harbour a variation of Haemophilus species. AB - H. haemolyticus is often misidentified as NTHi due to their close phylogenetic relationship. Differentiating between the two is important for correct identification and appropriate treatment of infective organism and to ensure any role of H. haemolyticus in disease is not being overlooked. Speciation however is not completely reliable by culture and PCR methods due to the loss of haemolysis by H. haemolyticus and the heterogeneity of NTHi. Haemophilus isolates from COPD as part of the AERIS study (ClinicalTrials - NCT01360398) were speciated by analysing sequence data for the presence of molecular markers. Further investigation into the genomic relationship was carried out using average nucleotide identity and phylogeny of allelic and genome alignments. Only 6.3% were identified as H. haemolyticus. Multiple in silico methods were able to distinguish H. haemolyticus from NTHi. However, no single gene target was found to be 100% accurate. A group of omp2 negative NTHi were observed to be phylogenetically divergent from H. haemolyticus and remaining NTHi. The presence of an atypical group from a geographically and disease limited set of isolates supports the theory that the heterogeneity of NTHi may provide a genetic continuum between NTHi and H. haemolyticus. PMID- 30282977 TI - Nuclear expansion and pore opening are instant signs of neuronal hypoxia and can identify poorly fixed brains. AB - The initial phase of neuronal death is not well characterized. Here, we show that expansion of the nuclear membrane without losing its integrity along with peripheralization of chromatin are immediate signs of neuronal injury. Importantly, these changes can be identified with commonly used nuclear stains and used as markers of poor perfusion-fixation. Although frozen sections are widely used, no markers are available to ensure that the observed changes were not confounded by perfusion-induced hypoxia/ischemia. Moreover, HMGB1 was immediately released and p53 translocated to mitochondria in hypoxic/ischemic neurons, whereas nuclear pore complex inhibitors prevented the nuclear changes, identifying novel neuroprotection targets. PMID- 30282978 TI - Coherently driven microcavity-polaritons and the question of superfluidity. AB - Due to their driven-dissipative nature, photonic quantum fluids present new challenges in understanding superfluidity. Some associated effects have been observed, and notably the report of nearly dissipationless flow for coherently driven microcavity-polaritons was taken as a smoking gun for superflow. Here, we show that the superfluid response-the difference between responses to longitudinal and transverse forces-is zero for coherently driven polaritons. This is a consequence of the gapped excitation spectrum caused by external phase locking. Furthermore, while a normal component exists at finite pump momentum, the remainder forms a rigid state that is unresponsive to either longitudinal or transverse perturbations. Interestingly, the total response almost vanishes when the real part of the excitation spectrum has a linear dispersion, which was the regime investigated experimentally. This suggests that the observed suppression of scattering should be interpreted as a sign of this new rigid state and not a superfluid. PMID- 30282979 TI - CLIC1 and CLIC4 complement CA125 as a diagnostic biomarker panel for all subtypes of epithelial ovarian cancer. AB - New plasma and tissue biomarkers of epithelial ovarian cancer (EOC) could improve early diagnosis and post-diagnosis clinical management. Here we investigated tissue staining and tissue secretion of CLIC1 and CLIC4 across EOC subtypes. CLIC1 and CLIC4 are two promising biomarkers we previously showed were elevated in EOC patient sera. Individually, CLIC1 or CLIC4 stained larger percentages of malignant tumors across all EOC subtypes compared with CA125, particularly early stage and mucinous tumors. CLIC4 also stained benign tumors but staining was limited to nuclei; whereas malignant tumors showed diffuse cellular staining of stromal and tumor cells. Both proteins were shed by all EOC subtypes tumors in short term organ culture at more consistent levels than CA125, supporting their potential as pan-subtype serum and tissue biomarkers. Elevated CLIC4 expression, but not CLIC1 expression, was a negative indicator of patient survival, and CLIC4 knockdown in cultured cells decreased cell proliferation and migration indicating a potential role in tumor progression. These results suggest CLIC1 and CLIC4 are promising serum and tissue biomarkers as well as potential therapeutic targets for all EOC subtypes. This justifies development of high throughput serum/plasma biomarker assays to evaluate utility of a biomarker panel consisting of CLIC1, CLIC4 and CA125. PMID- 30282981 TI - Mucociliary Clearance in Mice Measured by Tracking Trans-tracheal Fluorescence of Nasally Aerosolized Beads. AB - Mucociliary clearance (MCC) is the first line of defense in clearing airways. In genetically engineered mice, each component of this system (ciliary beat, mucus, airway surface hydration) can be studied separately to determine its contribution to MCC. Because MCC is difficult to measure in mice, MCC measurements are often omitted from these studies. We report a simple method to measure MCC in mice involving nasal inhalation of aerosolized fluorescent beads and trans-tracheal bead tracking. This method has a number of advantages over existing methods: (1) a small volume of liquid is deposited thus minimally disturbing the airway surface; (2) bead behavior on airways can be visualized; (3) useful for adult or neonatal mice; (4) the equipment is relatively inexpensive and easily obtainable. The type of anesthetic had no significant effect on the rate of MCC, but overloading the airways with beads significantly decreased MCC. In addition, the rate of bead transport was not different in alive (3.11 mm/min) vs recently euthanized mice (3.10 mm/min). A 5-min aerosolization of beads in a solution containing UTP significantly increased the rate of MCC, demonstrating that our method would be of value in testing the role of various pharmacological agents on MCC. PMID- 30282980 TI - Suppression of SUN2 by DNA methylation is associated with HSCs activation and hepatic fibrosis. AB - Hepatic myofibroblasts, activated hepatic stellate cells (HSCs), are the main cell type of extracellular matrix (ECM) deposition during hepatic fibrosis. Aberrant DNA methylation-regulated HSCs activation in liver fibrogenesis has been reported, but the functional roles and mechanisms of DNA methylation in hepatic fibrosis remain to be elucidated. In the present study, reduced representation bisulfite sequencing (RRBS) analysis of primary HSCs revealed hypermethylation patterns in hepatic fibrosis. Interestingly, we found SAD1/UNC84 domain protein-2 (SUN2) gene hypermethylation at CpG sites during liver fibrogenesis in mice with CCl4-induced hepatic fibrosis, which was accompanied by low expression of SUN2. In vivo overexpression of SUN2 following adeno-associated virus-9 (AAV9) administration inhibited CCl4-induced liver injury and reduced fibrogenesis marker expression. Consistently, in vitro experiments showed that enforced expression of SUN2 suppressed HSCs activation and exerted anti-fibrogenesis effects in TGF-beta1-activated HSC-T6 cells. In addition, the signaling mechanisms related to SUN2 expression were investigated in vivo and in vitro. Methyltransferase-3b (DNMT3b) is the principal regulator of SUN2 expression. Mechanistically, inhibition of protein kinase B (AKT) phosphorylation may be a crucial pathway for SUN2-mediated HSCs activation. In conclusion, these findings provide substantial new insights into SUN2 in hepatic fibrosis.

AB - While quasicrystals possess long-range orientational order they lack translation periodicity. Considerable advancements in the elucidation of their structures and formative principles contrast with comparatively uncharted interrelations, as studies bridging the spatial scales from atoms to the macroscale are scarce. Here, we report on the homogeneous nucleation of a single quasicrystalline seed from the undercooled melt of glass-forming NiZr and its continuous growth into a tenfold twinned dendritic microstructure. Observing a series of crystallization events on electrostatically levitated NiZr confirms homogeneous nucleation. Mapping the microstructure with electron backscatter diffraction suggests a unique, distortion-free structure merging a common structure type of binary alloys with a spiral growth mechanism resembling phyllotaxis. A general geometric description, relating all atomic loci, observed by atomic resolution electron microscopy, to a pentagonal [Formula: see text] module, explains how the seed's decagonal long-range orientational order is conserved throughout the symmetry breaking steps of twinning and dendritic growth. PMID- 30282983 TI - CPP-Ts: a new intracellular calcium channel modulator and a promising tool for drug delivery in cancer cells. AB - Scorpion sting envenoming impacts millions of people worldwide, with cardiac effects being one of the main causes of death on victims. Here we describe the first Ca2+ channel toxin present in Tityus serrulatus (Ts) venom, a cell penetrating peptide (CPP) named CPP-Ts. We show that CPP-Ts increases intracellular Ca2+ release through the activation of nuclear InsP3R of cardiomyocytes, thereby causing an increase in the contraction frequency of these cells. Besides proposing a novel subfamily of Ca2+ active toxins, we investigated its potential use as a drug delivery system targeting cancer cell nucleus using CPP-Ts's nuclear-targeting property. To this end, we prepared a synthetic CPP-Ts sub peptide14-39 lacking pharmacological activity which was directed to the nucleus of specific cancer cell lines. This research identifies a novel subfamily of Ca2+ active toxins and provides new insights into biotechnological applications of animal venoms. PMID- 30282984 TI - A toolbox for multiplexed super-resolution imaging of the E. coli nucleoid and membrane using novel PAINT labels. AB - Maintenance of the bacterial homeostasis initially emanates from interactions between proteins and the bacterial nucleoid. Investigating their spatial correlation requires high spatial resolution, especially in tiny, highly confined and crowded bacterial cells. Here, we present super-resolution microscopy using a palette of fluorescent labels that bind transiently to either the membrane or the nucleoid of fixed E. coli cells. The presented labels are easily applicable, versatile and allow long-term single-molecule super-resolution imaging independent of photobleaching. The different spectral properties allow for multiplexed imaging in combination with other localisation-based super-resolution imaging techniques. As examples for applications, we demonstrate correlated super resolution imaging of the bacterial nucleoid with the position of genetic loci, of nascent DNA in correlation to the entire nucleoid, and of the nucleoid of metabolically arrested cells. We furthermore show that DNA- and membrane targeting labels can be combined with photoactivatable fluorescent proteins and visualise the nano-scale distribution of RNA polymerase relative to the nucleoid in drug-treated E. coli cells. PMID- 30282985 TI - Human serum albumin alters specific genes that can play a role in survival and persistence in Acinetobacter baumannii. AB - In the past few decades Acinetobacter baumannii has emerged as a notorious nosocomial pathogen because of its ability to acquire genetic material and persist in extreme environments. Recently, human serum albumin (HSA) was shown to significantly increase natural transformation frequency in A. baumannii. This observation led us to perform transcriptomic analysis of strain A118 under HSA induction to identify genes that are altered by HSA. Our results revealed the statistically significant differential expression of 296 protein-coding genes, including those associated with motility, biofilm formation, metabolism, efflux pumps, capsule synthesis, and transcriptional regulation. Phenotypic analysis of these traits showed an increase in surface-associated motility, a decrease in biofilm formation, reduced activity of a citric acid cycle associated enzyme, and increased survival associated with zinc availability. Furthermore, the expression of genes known to play a role in pathogenicity and antibiotic resistance were altered. These genes included those associated with RND-type efflux pumps, the type VI secretion system, iron acquisition/metabolism, and beta-lactam resistance. Together, these results illustrate how human products, in particular HSA, may play a significant role in both survival and persistence of A. baumannii. PMID- 30282986 TI - An ultra-low thiourea catalyzed strain-release glycosylation and a multicatalytic diversification strategy. AB - The utility of thiourea catalysis in selective glycosylation strategies has gained significant momentum lately due to its versatility in hydrogen bonding or anionic recognition activation modes. The use of these non-covalent interactions constitute a powerful means to construct glycosidic linkages as it mimics physiologically occurring glycosyltransferases. However, glycosyl donor activation through the currently employed catalysts is moderate such that, in general, catalyst loadings are rather high in these transformations. In addition, thiourea catalysis has not been well explored for the synthesis of furanosides. Herein, we demonstrate an ultra-low loadings stereoselective and stereospecific thiourea catalyzed strain-release furanosylation and pyranosylation strategy. Our ultra-low organocatalyzed furanosylation enables a multicatalytic strategy, which opens up a unique avenue towards rapid diversification of synthetic glycosides. In-situ NMR monitoring unravel insights into unknown reaction intermediates and initial rate kinetic studies reveal a plausible synergistic hydrogen bonding/Bronsted acid activation mode. PMID- 30282988 TI - Maternal high-fat diet consumption induces sex-dependent alterations of the endocannabinoid system and redox homeostasis in liver of adult rat offspring. AB - Maternal diet plays a critical role in health development. Perinatal overnutrition induces metabolic dysfunctions and obesity in the offspring. Obesity is associated with endocannabinoid system (ECS) over activation and oxidative stress. Liver ECS activation induces hepatic steatosis, inflammation and fibrosis while the antagonism of cannabinoid receptors ameliorates these alterations. Here, we investigated the effect of perinatal maternal high-fat diet (HF, 29% of calories as fat) on the ECS and antioxidant system in liver of male and female adult rat offspring (180 days old). Maternal HF diet increased hepatic cannabinoid receptors, ECS metabolizing enzymes and triglyceride content, with male offspring more affected. ECS changes are likely independent of estradiol serum levels but associated with increased hepatic content of estrogen receptor, which can stimulate the expression of ECS components. Differently, maternal HF diet decreased the activity of the antioxidant enzymes glutathione peroxidase, superoxide dismutase and catalase, and increased oxidative stress markers in both sexes. Alterations in the redox homeostasis were associated with mitochondria damage but not with liver fibrosis. Our data suggest that maternal HF diet induces ECS over activation in adulthood, and that male offspring are at higher risk to develop liver disease compared with female rats. PMID- 30282987 TI - Bi-directional cell-pericellular matrix interactions direct stem cell fate. AB - Modifiable hydrogels have revealed tremendous insight into how physical characteristics of cells' 3D environment drive stem cell lineage specification. However, in native tissues, cells do not passively receive signals from their niche. Instead they actively probe and modify their pericellular space to suit their needs, yet the dynamics of cells' reciprocal interactions with their pericellular environment when encapsulated within hydrogels remains relatively unexplored. Here, we show that human bone marrow stromal cells (hMSC) encapsulated within hyaluronic acid-based hydrogels modify their surroundings by synthesizing, secreting and arranging proteins pericellularly or by degrading the hydrogel. hMSC's interactions with this local environment have a role in regulating hMSC fate, with a secreted proteinaceous pericellular matrix associated with adipogenesis, and degradation with osteogenesis. Our observations suggest that hMSC participate in a bi-directional interplay between the properties of their 3D milieu and their own secreted pericellular matrix, and that this combination of interactions drives fate. PMID- 30282989 TI - Polymerization driven monomer passage through monolayer chemical vapour deposition graphene. AB - Mass transport through graphene is receiving increasing attention due to the potential for molecular sieving. Experimental studies are mostly limited to the translocation of protons, ions, and water molecules, and results for larger molecules through graphene are rare. Here, we perform controlled radical polymerization with surface-anchored self-assembled initiator monolayer in a monomer solution with single-layer graphene separating the initiator from the monomer. We demonstrate that neutral monomers are able to pass through the graphene (via native defects) and increase the graphene defects ratio (Raman ID/IG) from ca. 0.09 to 0.22. The translocations of anionic and cationic monomers through graphene are significantly slower due to chemical interactions of monomers with the graphene defects. Interestingly, if micropatterned initiator monolayers are used, the translocations of anionic monomers apparently cut the graphene sheet into congruent microscopic structures. The varied interactions between monomers and graphene defects are further investigated by quantum molecular dynamics simulations. PMID- 30282991 TI - Social and nutritional factors shape larval aggregation, foraging, and body mass in a polyphagous fly. AB - The majority of insect species have a clearly defined larval stage during development. Larval nutrition is crucial for individuals' growth and development, and larval foraging success often depends on both resource availability and competition for those resources. To date, however, little is known about how these factors interact to shape larval development and behaviour. Here we manipulated the density of larvae of the polyphagous fruit fly pest Bactrocera tryoni ('Queensland fruit fly'), and the diet concentration of patches in a foraging arena to address this gap. Using advanced statistical methods of machine learning and linear regression models, we showed that high larval density results in overall high larval aggregation across all diets except in extreme diet dilutions. Larval aggregation was positively associated with larval body mass across all diet concentrations except in extreme diet dilutions where this relationship was reversed. Over time, larvae in low-density arenas also tended to aggregate while those in high-density arenas tended to disperse, an effect that was observed for all diet concentrations. Furthermore, larvae in high-density arenas displayed significant avoidance of low concentration diets - a behaviour that was not observed amongst larvae in low-density arenas. Thus, aggregation can help, rather than hinder, larval growth in high-density environments, and larvae may be better able to explore available nutrition when at high-density than when at low-density. PMID- 30282990 TI - Surface-modified three-dimensional graphene nanosheets as a stationary phase for chromatographic separation of chiral drugs. AB - Carbon-based stationary phases for chromatographic separation have been commercially available since the 1980s. Porous graphitic carbon liquid chromatography columns are known to be highly resistant to aggressive mobile phases and extreme pH values of solvents and eluents, an important advantage compared to conventional silica-based alternatives. In our work, we demonstrate a new variant of carbon-based stationary phases for liquid chromatography, specifically developed for chiral separation. Mesoporous three-dimensional graphene nanosheets (3D GNS), functionalized with tetracyanoethylene oxide (TCNEO) and (S)-(+)-2-pyrrolidinemethanol, demonstrate pharmaceutical-grade chiral separation of model ibuprofen and thalidomide racemic mixtures when used as Chiral Stationary Phases (CSPs), with performance parameters comparable to currently commercially available CSPs. Simple covalent attachment of functionalization groups to the surface of mesoporous three-dimensional graphene nanosheets makes these carbon-based CSPs chemically stable and up to an order of magnitude less expensive than standard silica-based analogues. PMID- 30282992 TI - Rich spatio-temporal stimulus dynamics unveil sensory specialization in cortical area S2. AB - Tactile perception in rodents depends on simultaneous, multi-whisker contacts with objects. Although it is known that neurons in secondary somatosensory cortex (wS2) respond to individual deflections of many whiskers, wS2's precise function remains unknown. The convergence of information from multiple whiskers into wS2 neurons suggests that they are good candidates for integrating multi-whisker information. Here, we apply stimulation patterns with rich dynamics simultaneously to 24 macro-vibrissae of rats while recording large populations of single neurons. Varying inter-whisker correlations without changing single whisker statistics, we observe pronounced supra-linear multi-whisker integration. Using novel analysis methods, we show that continuous multi-whisker movements contribute to the firing of wS2 neurons over long temporal windows, facilitating spatio-temporal integration. In contrast, primary cortex (wS1) neurons encode fine features of whisker movements on precise temporal scales. These results provide the first description of wS2's representation during multi-whisker stimulation and outline its specialized role in parallel to wS1 tactile processing. PMID- 30282994 TI - Ecto-Calreticulin is essential for an efficient immunogenic cell death stimulation in mouse melanoma. AB - Skin melanoma remains one of the most aggressive and difficult to treat human malignancy, with an increasing incidence every year. Although surgical resection represents the best therapeutic approach, this is only feasible in cases of early diagnosis. Furthermore, the established malignancy is resistant to all therapeutic strategies employed so far, resulting in an unacceptable patient survival rate. Although the immune-mediated therapeutic approaches, based on anti PD1 or anti-CTLA4, are very promising and under clinical trial experimentation, they could conceal not yet fully emerged pitfalls such as the development of autoimmune diseases. Therefore, alternative therapeutic approaches are still under investigation, such as the immunogenic cell death (ICD) process. Here we show that the lack of calreticulin translocation onto mouse melanoma cell membrane prevents the stimulation of an effective ICD response in vivo. PMID- 30282993 TI - Cloning of the wheat Yr15 resistance gene sheds light on the plant tandem kinase pseudokinase family. AB - Yellow rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a devastating fungal disease threatening much of global wheat production. Race specific resistance (R)-genes are used to control rust diseases, but the rapid emergence of virulent Pst races has prompted the search for a more durable resistance. Here, we report the cloning of Yr15, a broad-spectrum R-gene derived from wild emmer wheat, which encodes a putative kinase-pseudokinase protein, designated as wheat tandem kinase 1, comprising a unique R-gene structure in wheat. The existence of a similar gene architecture in 92 putative proteins across the plant kingdom, including the barley RPG1 and a candidate for Ug8, suggests that they are members of a distinct family of plant proteins, termed here tandem kinase-pseudokinases (TKPs). The presence of kinase-pseudokinase structure in both plant TKPs and the animal Janus kinases sheds light on the molecular evolution of immune responses across these two kingdoms. PMID- 30282995 TI - Novel millimeter-wave-based method for in situ cell isolation and other applications. AB - As an alternative to laser-based methods, we developed a novel in situ cell isolation method and instrument based on local water absorption of millimeter wave (MMW) radiation that occurs in cellular material and nearby culture medium while the cultureware materials (plastic and glass) are transparent to MMW frequencies. Unwanted cells within cell population are targeted with MMWs in order to kill them by overheating. The instrument rapidly (within 2-3 seconds) heats a cell culture area of about 500 um in diameter to 50 degrees C using a low-power W-band (94 GHz) MMW source. Heated cells in the area detach from the substrate and can be removed by a media change leaving a bare spot. Hence we named the instrument "CellEraser". Quick, local and non-contact heating with sharp boundaries of the heated area allows elimination of the unwanted cells without affecting the neighboring cells. The instrument is implemented as a compact microscope attachment and the selective hyperthermic treatment can be done manually or in an automated mode. Mammalian cells heated even momentarily above 50 degrees C will not survive. This "temperature of no return" does not compromise cellular membranes nor does it denature proteins. Using the CellEraser instrument we found that the key event that determines the fate of a cell at elevated temperatures is whether or not the selectivity of its nucleus is compromised. If a cell nucleus becomes "leaky" allowing normally excluded (cytoplasmic) proteins in and normally nuclear-localized proteins out, that cell is destined to die. Quick heating by MMWs to higher temperatures (70 degrees C) denatures cellular proteins but the cells are not able to detach from the substrate - instead they undergo a phenomenon we called "thermofixation": such cells look similar to cells fixed with common chemical fixatives. They remain flat and are not washable from the substrate. Interestingly, their membranes become permeable to DNA dyes and even to antibodies. Thermofixation allows the use of western blot antibodies for immunofluorescence imaging. PMID- 30282996 TI - Long noncoding RNA MEG3 regulates LATS2 by promoting the ubiquitination of EZH2 and inhibits proliferation and invasion in gallbladder cancer. AB - Gallbladder cancer (GBC) is the most common type of biliary tract cancer worldwide. Long noncoding RNAs (lncRNAs) play essential roles in physiological and pathological development. LncRNA MEG3, a tumor suppressor, has been reported to play important roles in some cancers, but the role of MEG3 in GBC remains largely unknown. The purpose of the present study was to explore the role of MEG3 in proliferation and invasion and the potential molecular mechanism in GBC. We found that MEG3 was downregulated in GBC tissues and cells, and low expression of MEG3 was correlated with poor prognostic outcomes in patients. Overexpression of MEG3 inhibited GBC cell proliferation and invasion, induced cell apoptosis and decreased tumorigenicity in nude mice. Moreover, we found that MEG3 was associated with EZH2 and attenuated EZH2 by promoting its ubiquitination. Furthermore, MEG3 executed its functions via EZH2 to regulate the downstream target gene LATS2. Taken together, these findings suggest that MEG3 is an effective target for GBC therapy and may facilitate the development of lncRNA directed diagnostics and therapeutics against GBC. PMID- 30282997 TI - Inhibition of the gyrA promoter by transcription-coupled DNA supercoiling in Escherichia coli. AB - The E. coli gyrA promoter (PgyrA) is a DNA supercoiling sensitive promoter, stimulated by relaxation of DNA templates, and inhibited by (-) DNA supercoiling in bacteria. However, whether PgyrA can be inhibited by transient and localized transcription-coupled DNA supercoiling (TCDS) has not been fully examined. In this paper, using different DNA templates including the E. coli chromosome, we show that transient and localized TCDS strongly inhibits PgyrA in E. coli. This result can be explained by a twin-supercoiled domain model of transcription in which (+) and (-) supercoiled domains are generated around the transcribing RNA polymerase. We also find that fluoroquinolones, such as ciprofloxacin, can substantially increase the expression of the firefly luciferase under the control of the PgyrA coupled to a divergent IPTG-inducible promoter in the presence of IPTG. This stimulation of PgyrA by fluoroquinolones can be also explained by the twin-supercoiled domain model of transcription. This unique property of TCDS may be configured into a high throughput-screening (HTS) assay to identify antimicrobial compounds targeting bacterial DNA gyrase. PMID- 30282998 TI - Critical deposition height for sustainable restoration via laser additive manufacturing. AB - Laser material deposition based restoration of high-value components can be a revolutionary technology in remanufacturing. The deposition process induces residual stresses due to thermomechanical behavior and metallurgical transformations. The presence of tensile residual stresses in the deposited layer will compromise the fatigue life of the restored component. We have developed a novel fully coupled metallurgical, thermal and mechanical (metallo thermomechanical) model to predict residual stresses and identified a critical deposition height, which ensures compressive residual stresses in the deposited layer. Any lower deposition height will result in tensile residual stresses and higher deposition height will result in excessive dilution (substrate melting). We have validated the model using neutron and micro-focus X-ray diffraction measurements. This study highlights that the critical deposition height corresponds to the minimum cooling rate during solidification. It addresses one of the major outstanding problems of additive manufacturing and paves a way for "science-enabled-technology" solutions for sustainable restoration/remanufacturing. PMID- 30282999 TI - Cholesterol is Inefficiently Converted to Cholesteryl Esters in the Blood of Cardiovascular Disease Patients. AB - Shotgun lipidomic analysis of 203 lipids in 13 lipid classes performed on blood plasma of donors who had just suffered an acute coronary syndrome (ACS, n = 74), or an ischemic stroke (IS, n = 21), or who suffer from stable angina pectoris (SAP, n = 78), and an age-matched control cohort (n = 52), showed some of the highest inter-lipid class correlations between cholesteryl esters (CE) and phosphatidylcholines (PC) sharing a common fatty acid. The concentration of lysophospatidylcholine (LPC) and ratios of concentrations of CE to free cholesterol (Chol) were also lower in the CVD cohorts than in the control cohort, indicating a deficient conversion of Chol to CE in the blood plasma in the CVD subjects. A non-equilibrium reaction quotient, Q', describing the global homeostasis of cholesterol as manifested in the blood plasma was shown to have a value in the CVD cohorts (Q'ACS = 0.217 +/- 0.084; Q'IS = 0.201 +/- 0.084; Q'SAP = 0.220 +/- 0.071) that was about one third less than in the control cohort (Q'Control = 0.320 +/- 0.095, p < 1 * 10-4), suggesting its potential use as a rapid predictive/diagnostic measure of CVD-related irregularities in cholesterol homeostasis. PMID- 30283000 TI - Protein-protein interactions reveal key canonical pathways, upstream regulators, interactome domains, and novel targets in ALS. AB - Developing effective treatment strategies for neurodegenerative diseases require an understanding of the underlying cellular pathways that lead to neuronal vulnerability and progressive degeneration. To date, numerous mutations in 147 distinct genes are identified to be "associated" with, "modifier" or "causative" of amyotrophic lateral sclerosis (ALS). Protein products of these genes and their interactions helped determine the protein landscape of ALS, and revealed upstream modulators, key canonical pathways, interactome domains and novel therapeutic targets. Our analysis originates from known human mutations and circles back to human, revealing increased PPARG and PPARGC1A expression in the Betz cells of sALS patients and patients with TDP43 pathology, and emphasizes the importance of lipid homeostasis. Downregulation of YWHAZ, a 14-3-3 protein, and cytoplasmic accumulation of ZFYVE27 especially in diseased Betz cells of ALS patients reinforce the idea that perturbed protein communications, interactome defects, and altered converging pathways will reveal novel therapeutic targets in ALS. PMID- 30283002 TI - Can neuroimaging help combat the opioid epidemic? A systematic review of clinical and pharmacological challenge fMRI studies with recommendations for future research. AB - The current opioid epidemic is an urgent public health problem, with enormous individual, societal, and healthcare costs. Despite effective, evidence-based treatments, there is significant individual variability in treatment responses and relapse rates are high. In addition, the neurobiology of opioid-use disorder (OUD) and its treatment is not well understood. This review synthesizes published fMRI literature relevant to OUD, with an emphasis on findings related to opioid medications and treatment, and proposes areas for further research. We conducted a systematic literature review of Medline and Psychinfo to identify (i) fMRI studies comparing OUD and control participants; (ii) studies related to medication, treatment, abstinence or withdrawal effects in OUD; and (iii) studies involving manipulation of the opioid system in healthy individuals. Following application of exclusionary criteria (e.g., insufficient sample size), 45 studies were retained comprising data from ~1400 individuals. We found convergent evidence that individuals with OUD display widespread heightened neural activation to heroin cues. This pattern is potentiated by heroin, attenuated by medication-assisted treatments for opioids, predicts treatment response, and is reduced following extended abstinence. Nonetheless, there is a paucity of literature examining neural characteristics of OUD and its treatment. We discuss limitations of extant research and identify critical areas for future neuroimaging studies, including the urgent need for studies examining prescription opioid users, assessing sex differences and utilizing a wider range of clinically relevant task-based fMRI paradigms across different stages of addiction. PMID- 30283001 TI - Deletion of the type 2 metabotropic glutamate receptor increases heroin abuse vulnerability in transgenic rats. AB - Opioid abuse is a rapidly growing public health crisis in the USA. Despite extensive research in the past decades, little is known about the etiology of opioid addiction or the neurobiological risk factors that increase vulnerability to opioid use and abuse. Recent studies suggest that the type 2 metabotropic glutamate receptor (mGluR2) is critically involved in substance abuse and addiction. In the present study, we evaluated whether low-mGluR2 expression may represent a risk factor for the development of opioid abuse and addiction using transgenic mGluR2-knockout (mGluR2-KO) rats. Compared to wild-type controls, mGluR2-KO rats exhibited higher nucleus accumbens (NAc) dopamine (DA) and locomotor responses to heroin, higher heroin self-administration and heroin intake, more potent morphine-induced analgesia and more severe naloxone precipitated withdrawal symptoms. In contrast, mGluR2-KO rats displayed lower motivation for heroin self-administration under high price progressive-ratio (PR) reinforcement conditions. Taken together, these findings suggest that mGluR2 may play an inhibitory role in opioid action, such that deletion of this receptor results in an increase in brain DA responses to heroin and in acute opioid reward and analgesia. Low-mGluR2 expression in the brain may therefore be a risk factor for the initial development of opioid abuse and addiction. PMID- 30283003 TI - Ancient proteins from ceramic vessels at Catalhoyuk West reveal the hidden cuisine of early farmers. AB - The analysis of lipids (fats, oils and waxes) absorbed within archaeological pottery has revolutionized the study of past diets and culinary practices. However, this technique can lack taxonomic and tissue specificity and is often unable to disentangle signatures resulting from the mixing of different food products. Here, we extract ancient proteins from ceramic vessels from the West Mound of the key early farming site of Catalhoyuk in Anatolia, revealing that this community processed mixes of cereals, pulses, dairy and meat products, and that particular vessels may have been reserved for specialized foods (e.g., cow milk and milk whey). Moreover, we demonstrate that dietary proteins can persist on archaeological artefacts for at least 8000 years, and that this approach can reveal past culinary practices with more taxonomic and tissue-specific clarity than has been possible with previous biomolecular techniques. PMID- 30283004 TI - Absence of Parallel Fibre to Purkinje Cell LTD During Eyeblink Conditioning. AB - Long-term depression (LTD) of parallel fibre/Purkinje cell synapses has been the favoured explanation for cerebellar motor learning such as classical eyeblink conditioning. Previous evidence against this interpretation has been contested. Here we wanted to test whether a classical conditioning protocol causes LTD. We applied a conditioning protocol, using a train of electrical pulses to the parallel fibres as the conditional stimulus. In order to rule out indirect effects caused by antidromic granule cell activation or output from Purkinje cells that might produce changes in Purkinje cell responsiveness, we focused the analysis on the first pulse in the conditional stimulus, that is, before any indirect effects would have time to occur. Purkinje cells learned to respond with a firing pause to the conditional stimulus. Yet, there was no depression of parallel fibre excitation after training. PMID- 30283005 TI - Profiling inflammatory markers in patients with pneumonia on intensive care. AB - Clinical investigations lack predictive value when diagnosing pneumonia, especially when patients are ventilated and develop ventilator associated pneumonia (VAP). New tools to aid diagnosis are important to improve outcomes. This pilot study examines the potential for a panel of inflammatory mediators to aid in the diagnosis. Forty-four ventilated patients, 17 with pneumonia and 27 with brain injuries, eight of whom developed VAP, were recruited. 51 inflammatory mediators, including cytokines and oxylipins, were measured in patients' serum using flow cytometry and mass spectrometry. The mediators could separate patients admitted to ICU with pneumonia compared to brain injury with an area under the receiver operating characteristic curve (AUROC) 0.75 (0.61-0.90). Changes in inflammatory mediators were similar in both groups over the course of ICU stay with 5,6-dihydroxyeicosatrienoic and 8,9-dihydroxyeicosatrienoic acids increasing over time and interleukin-6 decreasing. However, brain injured patients who developed VAP maintained inflammatory profiles similar to those at admission. A multivariate model containing 5,6-dihydroxyeicosatrienoic acid, 8,9 dihydroxyeicosatrienoic acid, intercellular adhesion molecule-1, interleukin-6, and interleukin-8, could differentiate patients with VAP from brain injured patients without infection (AUROC 0.94 (0.80-1.00)). The use of a selected group of markers showed promise to aid the diagnosis of VAP especially when combined with clinical data. PMID- 30283006 TI - Superconductivity at 38 K at an electrochemical interface between an ionic liquid and FeSe0.8Te0.2 on various substrates. AB - Superconducting FeSe0.8Te0.2 thin films on SrTiO3, LaAlO3 and CaF2 substrates were electrochemically etched in an ionic liquid, DEME-TFSI, electrolyte with a gate bias of 5 V. Superconductivity at 38 K was observed on all substrates after the etching of films with a thickness greater than 30 nm, despite the different Tc values of 8 K, 12 K and 19 K observed before etching on SrTiO3, LaAlO3 and CaF2 substrates, respectively. Tc returned to its original value with the removal of the gate bias. The observation of Tc enhancement for these thick films indicates that the Tc enhancement is unrelated to any interfacial effects between the film and the substrate. The sheet resistance and Hall coefficient of the surface conducting layer were estimated from the gate bias dependence of the transport properties. The sheet resistances of the surface conducting layers of the films on LaAlO3 and CaF2 showed identical temperature dependence, and the Hall coefficient was found to be almost independent of temperature and to take values of -0.05 to -0.2 m2/C, corresponding to 4-17 electrons per FeSe0.8Te0.2 unit cell area in two dimensions. These common transport properties on various substrates suggest that the superconductivity at 38 K appears in the surface conducting layer as a result of an electrochemical reaction between the surface of the FeSe0.8Te0.2 thin film and the ionic liquid electrolyte. PMID- 30283007 TI - Observation of the linewidth broadening of single spins in diamond nanoparticles in aqueous fluid and its relation to the rotational Brownian motion. AB - Capturing the fast rotational motion of single nanoparticles has been hindered owing to the difficulty of acquiring directional information under the optical diffraction limit. Here, we report the linewidth broadening of the electron spin resonance of single nitrogen vacancy (NV) centers that matches the rotational diffusion constant of the host nanodiamonds. When nanodiamonds are gradually detached from the substrates that they were fixed to, their optically detected spin resonance peaks are broadened by 1.8 MHz, which corresponds to the rotational diffusion constant of nanoparticles with a diameter of 11.4 nm from the Einstein-Smoluchowski relation. PMID- 30283009 TI - moxMaple3: a Photoswitchable Fluorescent Protein for PALM and Protein Highlighting in Oxidizing Cellular Environments. AB - The ability of fluorescent proteins (FPs) to fold robustly is fundamental to the autocatalytic formation of the chromophore. While the importance of the tertiary protein structure is well appreciated, the impact of individual amino acid mutations for FPs is often not intuitive and requires direct testing. In this study, we describe the engineering of a monomeric photoswitchable FP, moxMaple3, for use in oxidizing cellular environments, especially the eukaryotic secretory pathway. Surprisingly, a point mutation to replace a cysteine substantially improved the yield of correctly folded FP capable of chromophore formation, regardless of cellular environment. The improved folding of moxMaple3 increases the fraction of visibly tagged fusion proteins, as well as FP performance in PALM super-resolution microscopy, and thus makes moxMaple3 a robust monomeric FP choice for PALM and optical highlighting applications. PMID- 30283008 TI - Cytoplasmic localization of GRHL3 upon epidermal differentiation triggers cell shape change for epithelial morphogenesis. AB - Epithelial cell shape change is a pivotal driving force for morphogenesis of complex three-dimensional architecture. However, molecular mechanisms triggering shape changes of epithelial cells in the course of growth and differentiation have not been entirely elucidated. Grhl3 plays a crucial role as a downstream transcription factor of Wnt/beta-catenin in epidermal differentiation. Here, we show Grhl3 induced large, mature epidermal cells, enriched with actomyosin networks, from embryoid bodies in vitro. Such epidermal cells were apparently formed by the simultaneous activation of canonical and non-canonical Wnt signaling pathways. A nuclear transcription factor, GRHL3 is localized in the cytoplasm and cell membrane during epidermal differentiation. Subsequently, such extranuclear GRHL3 is essential for the membrane-associated expression of VANGL2 and CELSR1. Cytoplasmic GRHL3, thereby, allows epidermal cells to acquire mechanical properties for changes in epithelial cell shape. Thus, we propose that cytoplasmic localization of GRHL3 upon epidermal differentiation directly triggers epithelial morphogenesis. PMID- 30283010 TI - Bufonid herpesvirus 1 (BfHV1) associated dermatitis and mortality in free ranging common toads (Bufo bufo) in Switzerland. AB - Here we report the discovery and partial characterization of a novel herpesvirus tentatively named Bufonid herpesvirus 1 (BfHV1) from severe dermatitis in free ranging common toads (Bufo bufo) in Switzerland. The disease has been observed in toads every year since 2014, in spring, during the mating season, at different and distant locations. The virus is found in the skin and occasionally in the brain of infected toads. The genome of the virus is at least 158 Kb long and contains at least 152 open reading frames with a minimal length of 270 nt. The genome of BfHV1 contains all the signature genes that are present in alloherpesviruses.

AB - We present experimental and theoretical investigations on the polarization properties of a single- and a double-layer gold (Au) grating, serving as a wire grid polarizer. Two layers of Au gratings form a cavity that effectively modulates the transmission and reflection of linearly polarized light. Theoretical calculations based on a transfer matrix method reveals that the double-layer Au grating structure creates an optical cavity exhibiting Fabry Perot (FP) resonance modes. As compared to a single-layer grating, the FP cavity resonance modes of the double-layer grating significantly enhance the transmission of the transverse magnetic (TM) mode, while suppressing the transmission of the transverse electric (TE) mode. As a result, the extinction ratio of TM to TE transmission for the double-layer grating structure is improved by a factor of approximately 8 in the mid-wave infrared region of 3.4-6 MUm. Furthermore, excellent infrared imagery is obtained with over a 600% increase in the ratio of the TM-output voltage (Vtheta = 0 degrees ) to TE-output voltage (Vtheta = 90 degrees ). This double-layer Au grating structure has great potential for use in polarimetric imaging applications due to its superior ability to resolve linear polarization signatures.

AB - The generation of electrical voltage through the flow of an electrolyte over a charged surface may be used for energy transduction. Here, we show that enhanced electrical potential differences (i.e., streaming potential) may be obtained through the flow of salt water on liquid-filled surfaces that are infiltrated with a lower dielectric constant liquid, such as oil, to harness electrolyte slip and associated surface charge. A record-high figure of merit, in terms of the voltage generated per unit applied pressure, of 0.043 mV Pa-1 is obtained through the use of the liquid-filled surfaces. In comparison with air-filled surfaces, the figure of merit associated with the liquid-filled surface increases by a factor of 1.4. These results lay the basis for innovative surface charge engineering methodology for the study of electrokinetic phenomena at the microscale, with possible application in new electrical power sources. PMID- 30283013 TI - Feasibility and robustness of dynamic 18F-FET PET based tracer kinetic models applied to patients with recurrent high-grade glioma prior to carbon ion irradiation. AB - The aim of this study was to analyze the robustness and diagnostic value of different compartment models for dynamic 18F-FET PET in recurrent high-grade glioma (HGG). Dynamic 18F-FET PET data of patients with recurrent WHO grade III (n:7) and WHO grade IV (n: 9) tumors undergoing re-irradiation with carbon ions were analyzed by voxelwise fitting of the time-activity curves with a simplified and an extended one-tissue compartment model (1TCM) and a two-tissue compartment model (2TCM), respectively. A simulation study was conducted to assess robustness and precision of the 2TCM. Parameter maps showed enhanced detail on tumor substructure. Neglecting the blood volume VB in the 1TCM yields insufficient results. Parameter K1 from both 1TCM and 2TCM showed correlation with overall patient survival after carbon ion irradiation (p = 0.043 and 0.036, respectively). The 2TCM yields realistic estimates for tumor blood volume, which was found to be significantly higher in WHO IV compared to WHO III (p = 0.031). Simulations on the 2TCM showed that K1 yields good accuracy and robustness while k2 showed lowest stability of all parameters. The 1TCM provides the best compromise between parameter stability and model accuracy; however application of the 2TCM is still feasible and provides a more accurate representation of tracer kinetics at the cost of reduced robustness. Detailed tracer kinetic analysis of 18F-FET PET with compartment models holds valuable information on tumor substructures and provides additional diagnostic and prognostic value. PMID- 30283014 TI - Chronic lymphocytic leukemia treatment algorithm 2018. AB - The treatment landscape for patients with chronic lymphocytic leukemia (CLL) has changed considerably with the introduction of very effective oral targeted therapies (such as ibrutinib, idelalisib, and venetoclax), and next-generation anti-CD20 monoclonal antibodies (such as obinutuzumab). These agents lead to improved outcomes in CLL, even among patients with high-risk features, such as del17p13 or TP53 mutation and unmutated immunoglobulin heavy chain (IGHV) genes. Each of these treatments is associated with a unique toxicity profile; in the absence of randomized data, the choice of one type of treatment over another depends on the co-morbidities of the patient. Chemoimmunotherapy still plays an important role in the management of previously untreated CLL patients, particularly among young fit patients who have standard risk FISH profile and mutated IGHV genes. Richter's transformation of CLL remains a difficult complication to treat, although therapy with programmed death 1 inhibitors such as pembrolizumab and nivolumab has shown impressive responses in a subset of patients. Our ability to risk stratify CLL patients continues to evolve; the CLL International Prognostic Index (CLL-IPI) is the best validated tool in predicting time to first therapy among previously untreated patients. This review summarizes the current approach to risk stratification and management of CLL patients. PMID- 30283015 TI - Graphitic Carbon Electrodes on Flexible Substrate for Neural Applications Entirely Fabricated Using Infrared Nanosecond Laser Technology. AB - Neural interfaces for neuroscientific research are nowadays mainly manufactured using standard microsystems engineering technologies which are incompatible with the integration of carbon as electrode material. In this work, we investigate a new method to fabricate graphitic carbon electrode arrays on flexible substrates. The devices were manufactured using infrared nanosecond laser technology for both patterning all components and carbonizing the electrode sites. Two laser pulse repetition frequencies were used for carbonization with the aim of finding the optimum. Prototypes of the devices were evaluated in vitro in 30 mM hydrogen peroxide to mimic the post-surgery oxidative environment. The electrodes were subjected to 10 million biphasic pulses (39.5 MUC/cm2) to measure their stability under electrical stress. Their biosensing capabilities were evaluated in different concentrations of dopamine in phosphate buffered saline solution. Raman spectroscopy and x-ray photoelectron spectroscopy analysis show that the atomic percentage of graphitic carbon in the manufactured electrodes reaches the remarkable value of 75%. Results prove that the infrared nanosecond laser yields activated graphite electrodes that are conductive, non-cytotoxic and electrochemically inert. Their comprehensive assessment indicates that our laser induced carbon electrodes are suitable for future transfer into in vivo studies, including neural recordings, stimulation and neurotransmitters detection.

AB - Botulinum toxin (BTX) injections reduce muscle mobility and are commonly used to treat the appearance of glabellar frown lines. Research shows that this cosmetic treatment leads to a reduction in depression. This reduction is consistent with the theory of embodied emotions because patients have a reduced ability to frown and so receive less negative feedback associated with this action. The current research explored this effect and three further hypotheses for the effects of cosmetic BTX injections based on embodied emotions. It was hypothesised that treatment of crow's feet (or laughter lines) would reduce mood as patients' Duchenne smiles would be impaired. It was hypothesised that facial BTX treatments would impair emotional expression recognition because the ability to mimic emotions would be reduced. Finally, it was hypothesised that, as BTX treatments prevent facial expressions associated with sexual excitement, sexual function would be impaired after treatment. Twenty four BTX-treated and twelve matched participants (all female) were tested before and after treatment. Results found that BTX treatment of laughter lines was associated with increased depression scores. Further, BTX treatment was associated with reduced emotion recognition ability and sexual function. The current results add to our knowledge of the psychological effects of injections of powerful neurotoxins and broaden the scope of the embodiment of emotions. PMID- 30283018 TI - Glycerophosphatidylcholine PC(36:1) absence and 3'-phosphoadenylate (pAp) accumulation are hallmarks of the human glioma metabolome. AB - Glioma is the most prevalent malignant brain tumor. A comprehensive analysis of the glioma metabolome is still lacking. This study aims to explore new special metabolites in glioma tissues. A non-targeted human glioma metabolomics was performed by UPLC-Q-TOF/MS. The gene expressions of 18 enzymes associated with 3' phosphoadenylate (pAp) metabolism was examined by qRT-PCR. Those enzymes cover the primary metabolic pathway of pAp. We identified 15 new metabolites (13 lipids and 2 nucleotides) that were significantly different between the glioma and control tissues. Glycerophosphatidylcholine [PC(36:1)] content was high and pAp content was significantly low in the control brain (p < 0.01). In glioma tissues, PC(36:1) was not detected and pAp content was significantly increased. The gene expressions of 3'-nucleotidases (Inositol monophosphatase (IMPAD-1) and 3'(2'),5'-bisphosphate nucleotidase 1(BPNT-1)) were dramatically down-regulated. Meanwhile, the gene expression of 8 sulfotransferases (SULT), 2 phosphoadenosine phosphosulfate synthases (PAPSS-1 and PAPSS-2) and L-aminoadipate-semialdehyde dehydrogenase-phosphopante-theinyl transferase (AASDHPPT) were up-regulated. PC(36:1) absence and pAp accumulation are the most noticeable metabolic aberration in glioma. The dramatic down-regulation of IMPAD-1 and BPNT-1 are the primary cause for pAp dramatic accumulation. Our findings suggest that differential metabolites discovered in glioma could be used as potentially novel therapeutic targets or diagnostic biomarkers and that abnormal metabolism of lipids and nucleotides play roles in the pathogenesis of glioma. PMID- 30283019 TI - Reprogramming of regulatory network using expression uncovers sex-specific gene regulation in Drosophila. AB - Gene regulatory networks (GRNs) describe regulatory relationships between transcription factors (TFs) and their target genes. Computational methods to infer GRNs typically combine evidence across different conditions to infer context-agnostic networks. We develop a method, Network Reprogramming using EXpression (NetREX), that constructs a context-specific GRN given context specific expression data and a context-agnostic prior network. NetREX remodels the prior network to obtain the topology that provides the best explanation for expression data. Because NetREX utilizes prior network topology, we also develop PriorBoost, a method that evaluates a prior network in terms of its consistency with the expression data. We validate NetREX and PriorBoost using the "gold standard" E. coli GRN from the DREAM5 network inference challenge and apply them to construct sex-specific Drosophila GRNs. NetREX constructed sex-specific Drosophila GRNs that, on all applied measures, outperform networks obtained from other methods indicating that NetREX is an important milestone toward building more accurate GRNs. PMID- 30283020 TI - Creating a switchable optical cavity with controllable quantum-state mapping between two modes. AB - We describe how an ensemble of four-level atoms in the diamond-type configuration can be applied to create a fully controllable effective coupling between two cavity modes. The diamond-type configuration allows one to use a bimodal cavity that supports modes of different frequencies or different circular polarisations, because each mode is coupled only to its own transition. This system can be used for mapping a quantum state of one cavity mode onto the other mode on demand. Additionally, it can serve as a fast opening high-Q cavity system that can be easily and coherently controlled with laser fields. PMID- 30283022 TI - The interplay of exercise, placebo and nocebo effects on experimental pain. AB - Over the last few decades, placebo, and nocebo effects in general, have been investigated at rest. This proposed study explores whether they could work even when the experience of pain occurs during a movement. Exercise itself can have a hypoalgesic effect, suggesting that placebo- and exercise-induced hypoalgesia could foster pain reduction. In the present study, we investigated the interplay of exercise, placebo and nocebo effects on pain. To this aim, we developed a machine-controlled isotonic motor task to standardize the exercise across participants and used a well-validated model of placebo and nocebo manipulations with reinforced expectations via a conditioning procedure including visual cues paired with heat painful stimulations. Participants reported expectations and pain on a trial-by-trial basis. We found that the standardized isotonic exercise elicited a reduction of pain intensity. Moreover, both exercise and placebo induced comparable hypoalgesic effects. When the exercise was added, placebo and nocebo effects were influenced by expectations but were not affected by fatigue or sex differences. Exercise-, placebo- and nocebo-induced pain modulation are likely to work through distinct mechanisms and neurophysiological research is needed to fully exploit the implications for sport, rehabilitation and pain management. PMID- 30283021 TI - The relationship between transgenerational acquired resistance and global DNA methylation in Arabidopsis. AB - Progeny of heavily diseased plants develop transgenerational acquired resistance (TAR). In Arabidopsis, TAR can be transmitted over one stress-free generation. Although DNA methylation has been implicated in the regulation of TAR, the relationship between TAR and global DNA methylation remains unknown. Here, we characterised the methylome of TAR-expressing Arabidopsis at different generations after disease exposure. Global clustering of cytosine methylation revealed TAR-related patterns in the F3 generation, but not in the F1 generation. The majority of differentially methylated positions (DMPs) occurred at CG context in gene bodies. TAR in F3 progeny after one initial generation of disease, followed by two stress-free generations, was lower than TAR in F3 progeny after three successive generations of disease. This difference in TAR effectiveness was proportional to the intensity of differential methylation at a sub-set of cytosine positions. Comparison of TAR-related DMPs with previously characterised cytosine methylation in mutation accumulation lines revealed that ancestral disease stress preferentially acts on methylation-labile cytosine positions, but also extends to methylation-stable positions. Thus, the TAR-related impact of ancestral disease extends beyond stochastic variation in DNA methylation. Our study has shown that the Arabidopsis epigenome responds globally to disease in previous generations and we discuss its contribution to TAR. PMID- 30283024 TI - Conduction Mechanisms on High Retention Annealed MgO-based Resistive Switching Memory Devices. AB - We report on the conduction mechanisms of novel Ru/MgO/Cu and Ru/MgO/Ta resistive switching memory (RSM) devices. Current-voltage (I-V) measurements revealed Schottky emission (SE) as the dominant conduction mechanism in the high resistance state (HRS), which was validated by varying temperatures and transmission electron microscopy (TEM) results. Retention of more than 10 years at 85 degrees C was obtained for both Ru/MgO/Ta and Ru/MgO/Cu RSM devices. In addition, annealing processes greatly improved the consistency of HRS and LRS switching paths from cycle to cycle, exhibiting an average ON/OFF ratio of 102. Further TEM studies also highlighted the difference in crystallinity between different materials in Ru/MgO/Cu RSM devices, confirming Cu filament identification which was found to be 10 nm in width. PMID- 30283023 TI - Reappraising the microscopic anatomy of human testis: identification of telocyte networks in the peritubular and intertubular stromal space. AB - Telocytes are a recently described stromal cell type widely distributed in various organs including the female and male reproductive systems. This study was aimed to investigate for the first time the existence, distribution and characteristics of telocytes in normal human testis by an integrated morphological approach (immunohistochemistry, immunofluorescence and transmission electron microscopy). We found that telocytes displaying typical long and moniliform prolongations and coexpressing CD34 and PDGFRalpha formed networks in the outer layer of peritubular tissue and around Leydig cells and vessels in the intertubular stroma. Testicular telocytes were immunophenotypically negative for CD31, c-kit/CD117 as well as alpha-SMA, thus making them clearly distinguishable from myoid cells/myofibroblasts located in the inner layer of peritubular tissue. Transmission electron microscopy confirmed the presence of cells ultrastructurally identifiable as telocytes (i.e. cells with telopodes alternating podomers and podoms) in the aforementioned locations. Intercellular contacts between neighboring telocytes and telopodes were observed throughout the testicular stromal compartment. Telopodes intimately surrounded and often established close contacts with peritubular myoid cells/myofibroblasts, Leydig cells and vessels. Extracellular vesicles were also frequently detected near telopodes. In summary, we demonstrated that telocytes are a previously neglected stromal component of human testis with potential implications in tissue homeostasis deserving further investigation. PMID- 30283025 TI - Activity of a novel antimicrobial peptide against Pseudomonas aeruginosa biofilms. AB - With the increasing recognition of biofilms in human disease, the development of novel antimicrobial therapies is of critical importance. For example, in patients with cystic fibrosis (CF), the acquisition of host-adapted, chronic Pseudomonas aeruginosa infection is associated with a decline in lung function and increased mortality. Our objective was to test the in vitro efficacy of a membrane-active antimicrobial peptide we designed, termed 6K-F17 (sequence: KKKKKK-AAFAAWAAFAA NH2), against multidrug resistant P. aeruginosa biofilms. This peptide displays high antimicrobial activity against a range of pathogenic bacteria, yet is non hemolytic to human erythrocytes and non-toxic to human bronchial epithelial cells. In the present work, P. aeruginosa strain PAO1, and four multidrug resistant (MDR) isolates from chronically infected CF individuals, were grown as 48-hour biofilms in a static biofilm slide chamber model. These biofilms were then exposed to varying concentrations of 6K-F17 alone, or in the presence of tobramycin, prior to confocal imaging. Biofilm biovolume and viability were assessed. 6K-F17 was able to kill biofilms - even in the presence of sputum - and greatly reduce biofilm biovolume in PAO1 and MDR isolates. Strikingly, when used in conjunction with tobramycin, low doses of 6K-F17 significantly potentiated tobramycin killing, leading to biofilm destruction. PMID- 30283026 TI - Benefits of soil biochar amendments to tomato growth under saline water irrigation. AB - Biochar amendments have been used in agriculture to improve soil fertility and enhance crop productivity. A greenhouse experiment was conducted to test the hypothesis that biochar amendment could also enhance the productivity of salt affected soils. The trial was conducted over two consecutive growing seasons to investigate the effect of biochar amendment (four application rates as: B1 = 0%, B2 = 2%, B3 = 4%, and B4 = 8% by mass of soil) on yield and quality of tomatoes grown in a silt loam soil using non-saline water (I0 = 0.7 dS m-1) and saline water (I1 = 1 dS m-1; I2 = 3 dS m-1) irrigation. Furthermore, the study investigated the mechanism by which biochar addresses the salt stress on plant. The results showed that soil productivity as indicated by the vegetative growth and tomato yield components was adversely and significantly affected by saline water irrigation (P < 0.05). Tomato yield decreased from 689 +/- 35.6 to 533 +/- 79.0 g per plant as salinity of irrigation water increased from I0 to I2. Then, biochar amendment increased vegetative growth, yield, and quality parameters under saline irrigation water regimes, and ameliorated the salt stresses on crop growth. The highest (8.73 +/- 0.15 and 4.10 +/- 0.82 g kg-1) and the lowest (8.33 +/- 0.08 and 2.42 +/- 0.76 g kg-1) values of soil pH and soil organic matter were measured at B4I0 and B1I2 treatments, respectively. Also, the highest rate of biochar amendment combining with non-saline water irrigation (B4I0) produced tomato with the highest plant photosynthetic (17.08 +/- 0.19 MUmol m-2 s-1) and transpiration rate (8.16 +/- 0.18 mmol H2O m-2 s-1). Mechanically, biochar amendment reduced transient sodium ions by adsorption and released mineral nutrients such as potassium, calcium, and magnesium into the soil solution. Therefore, biochar amendments have the potential in ameliorating salt stress and enhancing tomato production. PMID- 30283028 TI - Ethical concerns regarding Danish genetic research. PMID- 30283029 TI - Double-blind, placebo-controlled, dose-ranging trial of intravenous ketamine as adjunctive therapy in treatment-resistant depression (TRD). AB - : Numerous placebo-controlled studies have demonstrated the ability of ketamine, an NMDA receptor antagonist, to induce rapid (within hours), transient antidepressant effects when administered intravenously (IV) at subanesthetic doses (0.5 mg/kg over 40 min). However, the optimal antidepressant dose remains unknown. We aimed to compare to active placebo the rapid acting antidepressant properties of a broad range of subanesthetic doses of IV ketamine among outpatients with treatment-resistant depression (TRD). A range of IV ketamine doses were compared to active placebo in the treatment of adult TRD over a 3-day period following a single infusion over 40 min. This was an outpatient study conducted across six US academic sites. Outpatients were 18-70 years old with TRD, defined as failure to achieve a satisfactory response (e.g., less than 50% improvement of depression symptoms) to at least two adequate treatment courses during the current depressive episode. Following a washout period, 99 eligible subjects were randomly assigned to one of the five arms in a 1:1:1:1:1 fashion: a single intravenous dose of ketamine 0.1 mg/kg (n = 18), a single dose of ketamine 0.2 mg/kg (n = 20), a single dose of ketamine 0.5 mg/kg (n = 22), a single dose of ketamine 1.0 mg/kg (n = 20), and a single dose of midazolam 0.045 mg/kg (active placebo) (n = 19). The study assessments (HAM-D-6, MADRS, SDQ, PAS, CGI S, and CGI-I) were performed at days 0, 1, 3 (endpoint), 5, 7, 14, and 30 to assess the safety and efficacy. The overall group * time interaction effect was significant for the primary outcome measure, the HAM-D-6. In post hoc pairwise comparisons controlling for multiple comparisons, standard dose (0.5 mg/kg) and high dose (1 mg/kg) of intravenous ketamine were superior to active placebo; a low dose (0.1 mg/kg) was significant only prior to adjustment (p = 0.02, p-adj = 0.14, d = -0.82 at day 1). Most of the interaction effect was due to differences at day 1, with no significant adjusted pairwise differences at day 3. This pattern generally held for secondary outcomes. The infusions of ketamine were relatively well tolerated compared to active placebo, except for greater dissociative symptoms and transient blood pressure elevations with the higher doses. Our results suggest that there is evidence for the efficacy of the 0.5 mg/kg and 1.0 mg/kg subanesthetic doses of IV ketamine and no clear or consistent evidence for clinically meaningful efficacy of lower doses of IV ketamine. TRIAL REGISTRATION: NCT01920555. PMID- 30283030 TI - Baseline brain structural and functional predictors of clinical outcome in the early course of schizophrenia. AB - Although schizophrenia is considered a brain disorder, the role of brain organization for symptomatic improvement remains inadequately defined. We investigated the relationship between baseline brain morphology, resting-state network connectivity and clinical response after 24-weeks of antipsychotic treatment in patients with schizophrenia (n = 95) using integrated multivariate analyses. There was no significant association between clinical response and measures of cortical thickness (r = 0.37, p = 0.98) and subcortical volume (r = 0.56, p = 0.15). By contrast, we identified a strong mode of covariation linking functional network connectivity to clinical response (r = 0.70; p = 0.04), and particularly to improvement in positive (weight = 0.62) and anxious/depressive symptoms (weight = 0.49). Higher internal cohesiveness of the default mode network was the single most important positive predictor. Key negative predictors involved the functional cohesiveness of central executive subnetworks anchored in the frontoparietal cortices and subcortical regions (including the thalamus and striatum) and the inter-network integration between the default mode and sensorimotor networks. The present findings establish links between clinical response and the functional organization of brain networks involved both in perception and in spontaneous and goal-directed cognition, thereby advancing our understanding of the pathophysiology of schizophrenia. PMID- 30283027 TI - The intellectual disability gene PQBP1 rescues Alzheimer's disease pathology. AB - Early-phase pathologies of Alzheimer's disease (AD) are attracting much attention after clinical trials of drugs designed to remove beta-amyloid (Abeta) aggregates failed to recover memory and cognitive function in symptomatic AD patients. Here, we show that phosphorylation of serine/arginine repetitive matrix 2 (SRRM2) at Ser1068, which is observed in the brains of early phase AD mouse models and postmortem end-stage AD patients, prevents its nuclear translocation by inhibiting interaction with T-complex protein subunit alpha. SRRM2 deficiency in neurons destabilized polyglutamine binding protein 1 (PQBP1), a causative gene for intellectual disability (ID), greatly affecting the splicing patterns of synapse-related genes, as demonstrated in a newly generated PQBP1-conditional knockout model. PQBP1 and SRRM2 were downregulated in cortical neurons of human AD patients and mouse AD models, and the AAV-PQBP1 vector recovered RNA splicing, the synapse phenotype, and the cognitive decline in the two mouse models. Finally, the kinases responsible for the phosphorylation of SRRM2 at Ser1068 were identified as ERK1/2 (MAPK3/1). These results collectively reveal a new aspect of AD pathology in which a phosphorylation signal affecting RNA splicing and synapse integrity precedes the formation of extracellular Abeta aggregates and may progress in parallel with tau phosphorylation. PMID- 30283031 TI - Integrative approach to sporadic Alzheimer's disease: deficiency of TYROBP in a tauopathy mouse model reduces C1q and normalizes clinical phenotype while increasing spread and state of phosphorylation of tau. AB - TYROBP/DAP12 forms complexes with ectodomains of immune receptors (TREM2, SIRPbeta1, CR3) associated with Alzheimer's disease (AD) and is a network hub and driver in the complement subnetwork identified by multi-scale gene network studies of postmortem human AD brain. Using transgenic or viral approaches, we characterized in mice the effects of TYROBP deficiency on the phenotypic and pathological evolution of tauopathy. Biomarkers usually associated with worsening clinical phenotype (i.e., hyperphosphorylation and increased tauopathy spreading) were unexpectedly increased in MAPTP301S;Tyrobp-/- mice despite the improved learning behavior and synaptic function relative to controls with normal levels of TYROBP. Notably, levels of complement cascade initiator C1q were reduced in MAPTP301S;Tyrobp-/- mice, consistent with the prediction that C1q reduction exerts a neuroprotective effect. These observations suggest a model wherein TYROBP-KO-(knock-out)-associated reduction in C1q is associated with normalized learning behavior and electrophysiological properties in tauopathy model mice despite a paradoxical evolution of biomarker signatures usually associated with neurological decline. PMID- 30283032 TI - Integrative approach to sporadic Alzheimer's disease: deficiency of TYROBP in cerebral Abeta amyloidosis mouse normalizes clinical phenotype and complement subnetwork molecular pathology without reducing Abeta burden. AB - Integrative gene network approaches enable new avenues of exploration that implicate causal genes in sporadic late-onset Alzheimer's disease (LOAD) pathogenesis, thereby offering novel insights for drug-discovery programs. We previously constructed a probabilistic causal network model of sporadic LOAD and identified TYROBP/DAP12, encoding a microglial transmembrane signaling polypeptide and direct adapter of TREM2, as the most robust key driver gene in the network. Here, we show that absence of TYROBP/DAP12 in a mouse model of AD type cerebral Abeta amyloidosis (APPKM670/671NL/PSEN1Deltaexon9) recapitulates the expected network characteristics by normalizing the transcriptome of APP/PSEN1 mice and repressing the induction of genes involved in the switch from homeostatic microglia to disease-associated microglia (DAM), including Trem2, complement (C1qa, C1qb, C1qc, and Itgax), Clec7a and Cst7. Importantly, we show that constitutive absence of TYROBP/DAP12 in the amyloidosis mouse model prevented appearance of the electrophysiological and learning behavior alterations associated with the phenotype of APPKM670/671NL/PSEN1Deltaexon9 mice. Our results suggest that TYROBP/DAP12 could represent a novel therapeutic target to slow, arrest, or prevent the development of sporadic LOAD. These data establish that the network pathology observed in postmortem human LOAD brain can be faithfully recapitulated in the brain of a genetically manipulated mouse. These data also validate our multiscale gene networks by demonstrating how the networks intersect with the standard neuropathological features of LOAD. PMID- 30283033 TI - Cocaine-induced ischemia in prefrontal cortex is associated with escalation of cocaine intake in rodents. AB - Cocaine-induced vasoconstriction reduces blood flow, which can jeopardize neuronal function and in the prefrontal cortex (PFC) it may contribute to compulsive cocaine intake. Here, we used integrated optical imaging in a rat self administration and a mouse noncontingent model, to investigate whether changes in the cerebrovascular system in the PFC contribute to cocaine self-administration, and whether they recover with detoxification. In both animal models, cocaine induced severe vasoconstriction and marked reductions in cerebral blood flow (CBF) in the PFC, which were exacerbated with chronic exposure and with escalation of cocaine intake. Though there was a significant proliferation of blood vessels in areas of vasoconstriction (angiogenesis), CBF remained reduced even after 1 month of detoxification. Treatment with Nifedipine (Ca2+ antagonist and vasodilator) prevented cocaine-induced CBF decreases and neuronal Ca2+ changes in the PFC, and decreased cocaine intake and blocked reinstatement of drug seeking. These findings provide support for the hypothesis that cocaine induced CBF reductions lead to neuronal deficits that contribute to hypofrontality and to compulsive-like cocaine intake in addiction, and document that these deficits persist at least one month after detoxification. Our preliminary data showed that nifedipine might be beneficial in preventing cocaine induced vascular toxicity and in reducing cocaine intake and preventing relapse. PMID- 30283034 TI - Uncovering the complex genetics of human character. AB - Human personality is 30-60% heritable according to twin and adoption studies. Hundreds of genetic variants are expected to influence its complex development, but few have been identified. We used a machine learning method for genome-wide association studies (GWAS) to uncover complex genotypic-phenotypic networks and environmental interactions. The Temperament and Character Inventory (TCI) measured the self-regulatory components of personality critical for health (i.e., the character traits of self-directedness, cooperativeness, and self transcendence). In a discovery sample of 2149 healthy Finns, we identified sets of single-nucleotide polymorphisms (SNPs) that cluster within particular individuals (i.e., SNP sets) regardless of phenotype. Second, we identified five clusters of people with distinct profiles of character traits regardless of genotype. Third, we found 42 SNP sets that identified 727 gene loci and were significantly associated with one or more of the character profiles. Each character profile was related to different SNP sets with distinct molecular processes and neuronal functions. Environmental influences measured in childhood and adulthood had small but significant effects. We confirmed the replicability of 95% of the 42 SNP sets in healthy Korean and German samples, as well as their associations with character. The identified SNPs explained nearly all the heritability expected for character in each sample (50 to 58%). We conclude that self-regulatory personality traits are strongly influenced by organized interactions among more than 700 genes despite variable cultures and environments. These gene sets modulate specific molecular processes in brain for intentional goal-setting, self-reflection, empathy, and episodic learning and memory. PMID- 30283035 TI - Dose response of the 16p11.2 distal copy number variant on intracranial volume and basal ganglia. AB - Carriers of large recurrent copy number variants (CNVs) have a higher risk of developing neurodevelopmental disorders. The 16p11.2 distal CNV predisposes carriers to e.g., autism spectrum disorder and schizophrenia. We compared subcortical brain volumes of 12 16p11.2 distal deletion and 12 duplication carriers to 6882 non-carriers from the large-scale brain Magnetic Resonance Imaging collaboration, ENIGMA-CNV. After stringent CNV calling procedures, and standardized FreeSurfer image analysis, we found negative dose-response associations with copy number on intracranial volume and on regional caudate, pallidum and putamen volumes (beta = -0.71 to -1.37; P < 0.0005). In an independent sample, consistent results were obtained, with significant effects in the pallidum (beta = -0.95, P = 0.0042). The two data sets combined showed significant negative dose-response for the accumbens, caudate, pallidum, putamen and ICV (P = 0.0032, 8.9 * 10-6, 1.7 * 10-9, 3.5 * 10-12 and 1.0 * 10-4, respectively). Full scale IQ was lower in both deletion and duplication carriers compared to non-carriers. This is the first brain MRI study of the impact of the 16p11.2 distal CNV, and we demonstrate a specific effect on subcortical brain structures, suggesting a neuropathological pattern underlying the neurodevelopmental syndromes.

AB - Maternal mental illness can have a devastating effect during the perinatal period, and has a profound impact on the care that the baby receives and on the relationships that the baby forms. This review summarises clinical evidence showing the effects of perinatal depression on offspring physical and behavioural development, and on the transmission of psychopathology between generations. We then evaluate a number of factors which influence this relationship, such as genetic factors, the use of psychotropic medications during pregnancy, the timing within the perinatal period, the sex of the foetus, and exposure to maltreatment in childhood. Finally, we examine recent findings regarding the molecular mechanisms underpinning these clinical observations, and identify relevant epigenetic and biomarker changes in the glucocorticoid, oxytocin, oestrogen and immune systems, as key biological mediators of these clinical findings. By understanding these molecular mechanisms in more detail, we will be able to improve outcomes for both mothers and their offspring for generations. PMID- 30283037 TI - Adolescent exposure to Delta9-tetrahydrocannabinol alters the transcriptional trajectory and dendritic architecture of prefrontal pyramidal neurons. AB - Neuronal circuits within the prefrontal cortex (PFC) mediate higher cognitive functions and emotional regulation that are disrupted in psychiatric disorders. The PFC undergoes significant maturation during adolescence, a period when cannabis use in humans has been linked to subsequent vulnerability to psychiatric disorders such as addiction and schizophrenia. Here, we investigated in a rat model the effects of adolescent exposure to Delta9-tetrahydrocannabinol (THC), a psychoactive component of cannabis, on the morphological architecture and transcriptional profile of layer III pyramidal neurons-using cell type- and layer specific high-resolution microscopy, laser capture microdissection and next generation RNA-sequencing. The results confirmed known normal expansions in basal dendritic arborization and dendritic spine pruning during the transition from late adolescence to early adulthood that were accompanied by differential expression of gene networks associated with neurodevelopment in control animals. In contrast, THC exposure disrupted the normal developmental process by inducing premature pruning of dendritic spines and allostatic atrophy of dendritic arborization in early adulthood. Surprisingly, there was minimal overlap of the developmental transcriptomes between THC- and vehicle-exposed rats. THC altered functional gene networks related to cell morphogenesis, dendritic development, and cytoskeleton organization. Marked developmental network disturbances were evident for epigenetic regulators with enhanced co-expression of chromatin- and dendrite-related genes in THC-treated animals. Dysregulated PFC co-expression networks common to both the THC-treated animals and patients with schizophrenia were enriched for cytoskeletal and neurite development. Overall, adolescent THC exposure altered the morphological and transcriptional trajectory of PFC pyramidal neurons, which could enhance vulnerability to psychiatric disorders. PMID- 30283039 TI - Cold-season disasters on the Eurasian steppes: Climate-driven or man-made. AB - Socio-ecological damage from climate-related disasters has increased worldwide, including a type of cold-season disaster (dzud) that is unique to the Eurasian steppes, notably Mongolia. During 2000-2014, dzuds killed approximately 30 million livestock and impacted the Mongolian socio-economy. The contributions of both natural and social processes to livestock mortality were not previously considered across Mongolia. Here, we consider the contribution of both multiple climate hazards (drought, cold temperatures and snow), and socioeconomic vulnerability (herders' livestock and coping-capacity) to mortality risk. We performed multi-regression analyses for each province using meteorological, livestock and socioeconomic datasets. Our results show that 93.5% of mortality within Mongolia was caused by a combination of multi-hazards (47.3%) and vulnerability (46.2%), suggesting dzuds were both climate- and man-made. However, in high-mortality hotspots, mortality was primarily caused by multi-hazards (drought-induced pasture deficiency and deep-snow). Livestock overpopulation and a lack of coping capacities that caused inadequate preparedness (e.g., hay/forage) were the main vulnerability factors. Frequent and severe multi hazards greatly increased the mortality risk, while increased vulnerability caused by socioeconomic changes in Mongolia since the 1990s tended to amplify the effects of multi-hazards. Thus, reductions in herder vulnerability within high mortality hotspots would likely be an effective means of mitigating the risk of future dzuds. PMID- 30283038 TI - Combined impacts of deforestation and wildlife trade on tropical biodiversity are severely underestimated. AB - Tropical forest diversity is simultaneously threatened by habitat loss and exploitation for wildlife trade. Quantitative conservation assessments have previously considered these threats separately, yet their impacts frequently act together. We integrate forest extent maps in 2000 and 2015 with a method of quantifying exploitation pressure based upon a species' commercial value and forest accessibility. We do so for 308 forest-dependent bird species, of which 77 are commercially traded, in the Southeast Asian biodiversity hotspot of Sundaland. We find 89% (274) of species experienced average habitat losses of 16% and estimate exploitation led to mean population declines of 37%. Assessing the combined impacts of deforestation and exploitation indicates the average losses of exploited species are much higher (54%), nearly doubling the regionally endemic species (from 27 to 51) threatened with extinction that should be IUCN Red Listed. Combined assessment of major threats is vital to accurately quantify biodiversity loss. PMID- 30283040 TI - Effect of statins on experimental postoperative adhesion: a systematic review and meta-analysis. AB - Adhesion is a significant concern after surgery. Many researchers studied the anti-adhesive effect of statin, of which results were inconsistent. Thus, we purposed to perform a systematic review and meta-analysis to evaluate the effect of statins on postoperative adhesion in an experimental study. A comprehensive search was conducted using MEDLINE, EMBASE, and Google Scholar to identify animal studies that investigated the postoperative anti-adhesive effect of statins applied at the surgical area. Primary outcome measure was gross adhesion score. Secondary outcomes included microscopic adhesion score and tissue plasminogen activator (t-PA) activity. Totally, 298 rats from 9 animal studies (172 rats received statin therapy and 126 rats received placebo or no treatment) were included in the final analysis. The combined results showed that gross and microscopic adhesion scores were significantly lower in the statin group in comparison to the control group (standardized mean difference [SMD] = 1.65, 95% confidence interval [CI]: 1.02 to 2.28, Pchi2 < 0.001, I2 = 77.9%; SMD = 1.90, 95% CI: 1.10 to 2.79, Pchi2 < 0.001, I2 = 84.5%, respectively). However, there was no evidence of a difference in t-PA activity (SMD = -3.43, 95% CI: -7.95 to 1.09, Pchi2 < 0.001, I2 = 95.5%). In conclusion, statins were effective in preventing postoperative adhesion, as assessed based on gross and microscopic adhesion scores in rats. PMID- 30283041 TI - Copper pollution exacerbates the effects of ocean acidification and warming on kelp microscopic early life stages. AB - Ocean warming (OW), ocean acidification (OA) and their interaction with local drivers, e.g., copper pollution, may negatively affect macroalgae and their microscopic life stages. We evaluated meiospore development of the kelps Macrocystis pyrifera and Undaria pinnatifida exposed to a factorial combination of current and 2100-predicted temperature (12 and 16 degrees C, respectively), pH (8.16 and 7.65, respectively), and two copper levels (no-added-copper and species-specific germination Cu-EC50). Meiospore germination for both species declined by 5-18% under OA and ambient temperature/OA conditions, irrespective of copper exposure. Germling growth rate declined by >40%.day-1, and gametophyte development was inhibited under Cu-EC50 exposure, compared to the no-added-copper treatment, irrespective of pH and temperature. Following the removal of copper and 9-day recovery under respective pH and temperature treatments, germling growth rates increased by 8-18%.day-1. The exception was U. pinnatifida under OW/OA, where growth rate remained at 10%.day-1 before and after copper exposure. Copper-binding ligand concentrations were higher in copper-exposed cultures of both species, suggesting that ligands may act as a defence mechanism of kelp early life stages against copper toxicity. Our study demonstrated that copper pollution is more important than global climate drivers in controlling meiospore development in kelps as it disrupts the completion of their life cycle. PMID- 30283042 TI - Human neural stem cell transplantation improves cognition in a murine model of Alzheimer's disease. AB - Stem cell transplantation offers a potentially transformative approach to treating neurodegenerative disorders. The safety of cellular therapies is established in multiple clinical trials, including our own in amyotrophic lateral sclerosis. To initiate similar trials in Alzheimer's disease, efficacious cell lines must be identified. Here, we completed a preclinical proof-of-concept study in the APP/PS1 murine model of Alzheimer's disease. Human neural stem cell transplantation targeted to the fimbria fornix significantly improved cognition in two hippocampal-dependent memory tasks at 4 and 16 weeks post-transplantation. While levels of synapse-related proteins and cholinergic neurons were unaffected, amyloid plaque load was significantly reduced in stem cell transplanted mice and associated with increased recruitment of activated microglia. In vitro, these same neural stem cells induced microglial activation and amyloid phagocytosis, suggesting an immunomodulatory capacity. Although long-term transplantation resulted in significant functional and pathological improvements in APP/PS1 mice, stem cells were not identified by immunohistochemistry or PCR at the study endpoint. These data suggest integration into native tissue or the idea that transient engraftment may be adequate for therapeutic efficacy, reducing the need for continued immunosuppression. Overall, our results support further preclinical development of human neural stem cells as a safe and effective therapy for Alzheimer's disease. PMID- 30283043 TI - Closing water productivity gaps to achieve food and water security for a global maize supply. AB - To achieve food and water security, it is as important to close the water productivity (WP) gap (which was defined as the difference between the maximum attainable WP and the currently achieved WP at the field scale) as it is to close yield gaps. However, few studies have provided quantitative estimates of existing WP gaps and constraining factors for global maize production. Using a meta analysis of 473 published studies covering 31 countries and 5,553 observations (932 site-years), we found the global average WP value for irrigated maize was 18.6 kg ha-1 mm-1. These WPs varied by factors such as seasonal precipitation, irrigation regimes, soil organic matter and soil pH. In current production systems, there exists a huge scope for improvement in maize WP, but the reported field experiments achieved only 20-46% of potential WP across all countries. Considering the future, raising WP to 85% of potential WP by 2050, a 100% increase in maize production could be achieved with 20% less planted area and 21% less water consumption than in 2005. Closing the WP gap may be critical to ensuring food security and achieving sustainable global agriculture. PMID- 30283044 TI - Tobacco smoking and the risk of abdominal aortic aneurysm: a systematic review and meta-analysis of prospective studies. AB - Several studies have found that smoking increases the risk of abdominal aortic aneurysm, however, the strength of the association has differed between studies and data from cohort studies have not yet been summarized. A systematic review and meta-analysis was therefore conducted to clarify this association. We searched PubMed and Embase databases up to May 2nd 2018. A random effects model was used to estimate summary relative risks (RRs) and 95% confidence intervals (CIs). Twenty three prospective studies were included. Comparing current, former and ever smokers with never smokers the summary RRs were 4.87 (95% CI: 3.93-6.02, I2 = 92%, n = 20), 2.10 (95% CI: 1.76-2.50, I2 = 71%, n = 15) and 3.28 (95% CI: 2.60-4.15, I2 = 96%, n = 18), respectively. The summary RR was 1.87 (95% CI: 1.45 2.40, I2 = 97%) per 10 cigarettes per day, 1.78 (95% CI: 1.54-2.06, I2 = 83%) per 10 pack-years was and 0.45 (95% CI: 0.32-0.63, I2 = 92.3%) per 10 years of smoking cessation. There was evidence of nonlinearity for cigarettes per day and pack-years (pnonlinearity < 0.0001 and pnonlinearity = 0.02, respectively), but not for smoking cessation, pnonlinearity = 0.85. Among smokers who quit, the RR was similar to that of never smokers by 25 years of smoking cessation. These findings confirm a strong association between smoking and the risk of developing abdominal aortic aneurysms. PMID- 30283045 TI - Influence of ylHog1 MAPK kinase on Yarrowia lipolytica stress response and erythritol production. AB - Erythritol production is a unique response to hyperosmotic stress that is observed in a small group of yeasts, including Yarrowia lipolytica. This study investigated whether this unusual mechanism is regulated by the HOG pathway, well described in Saccharomyces cerevisiae. The gene YALI0E25135g was identified as the Y. lipolytica homologue of HOG1 and was found to be phosphorylated in response to hyperosmotic shock. Deletion of the gene caused a significant decrease in resistance to hyperosmotic stress and negatively affected erythritol production. Interestingly, the deletion strain yl-hog1Delta displayed significant morphological defects, with the cells growing in a filamentous form. Moreover, yl hog1Delta cells were also resistant to the cell wall damaging agents Congo red and calcofluor white. Collectively, these results indicate that yl-Hog1 is crucial for the cellular response to hyperosmotic stress, plays a role in the induction of erythritol production, and potentially prevents cross-talk with different MAPK signalling pathways in the cell. PMID- 30283046 TI - Impaired platelet activity and hypercoagulation in healthy term and moderately preterm newborns during the early neonatal period. AB - BACKGROUND: Preterm newborns are at thrombohemorrhagic risk during the early neonatal period. Taking into account the lack of informative tools for the laboratory diagnosis of hemostasis disorders in newborns, our goal was to determine the baseline values of thrombodynamics and platelet functional activity in healthy term and moderately preterm newborns during the early neonatal period future potential clinical use of these tests. METHODS: Coagulation was assessed using an integral assay of thrombodynamics and standard coagulation assays, and platelet functional activity was estimated by flow cytometry. RESULTS: Hypercoagulation of newborns, represented by a significantly higher clot growth velocity and the presence of spontaneous clots in the thrombodynamics, was combined with platelet hypoactivity. Granule release, phosphatidylserine exposure, and the ability to change shape upon activation were decreased in the platelets of moderately preterm newborns. The platelet function remained at the same level over the first four days of life, whereas the hypercoagulation became less pronounced. CONCLUSIONS: The hemostasis of newborns is characterized by hypercoagulation combined with reduced platelet functional activity. Moderately preterm and term newborns do not differ in the parameters of coagulation, while some of the functional responses of platelets are lower in moderately preterm newborns than in term. PMID- 30283047 TI - The contribution of the gut microbiome to neurodevelopment and neuropsychiatric disorders. AB - Bidirectional communication between the gut and brain is well recognized, with data now accruing for a specific role of the gut microbiota in that link, referred to as the microbiome-gut-brain axis. This review will discuss the emerging role of the gut microbiota in brain development and behavior. Animal studies have clearly demonstrated effects of the gut microbiota on gene expression and neurochemical metabolism impacting behavior and performance. Based on these changes, a modulating role of the gut microbiota has been demonstrated for a variety of neuropsychiatric disorders, including depression, anxiety, and movement including Parkinson's, and importantly for the pediatric population autism. Critical developmental windows that influence early behavioral outcomes have been identified that include both the prenatal environment and early postnatal colonization periods. The clearest data regarding the role of the gut microbiota on neurodevelopment and psychiatric disorders is from animal studies; however, human data have begun to emerge, including an association between early colonization patterns and cognition. The importance of understanding the contribution of the gut microbiota to the development and functioning of the nervous system lies in the potential to intervene using novel microbial-based approaches to treating neurologic conditions. While pathways of communication between the gut and brain are well established, the gut microbiome is a new component of this axis. The way in which organisms that live in the gut influence the central nervous system (CNS) and host behavior is likely to be multifactorial in origin. This includes immunologic, endocrine, and metabolic mechanisms, all of which are pathways used for other microbial-host interactions. Germ-free (GF) mice are an important model system for understanding the impact of gut microbes on development and function of the nervous system. Alternative animal model systems have further clarified the role of the gut microbiota, including antibiotic treatment, fecal transplantation, and selective gut colonization with specific microbial organisms. Recently, researchers have started to examine the human host as well. This review will examine the components of the CNS potentially influenced by the gut microbiota, and the mechanisms mediating these effects. Links between gut microbial colonization patterns and host behavior relevant to a pediatric population will be examined, highlighting important developmental windows in utero or early in development.

PMID- 30283051 TI - A Dexterous, Glove-Based Teleoperable Low-Power Soft Robotic Arm for Delicate Deep-Sea Biological Exploration. AB - Modern marine biologists seeking to study or interact with deep-sea organisms are confronted with few options beyond industrial robotic arms, claws, and suction samplers. This limits biological interactions to a subset of "rugged" and mostly immotile fauna. As the deep sea is one of the most biologically diverse and least studied ecosystems on the planet, there is much room for innovation in facilitating delicate interactions with a multitude of organisms. The biodiversity and physiology of shallow marine systems, such as coral reefs, are common study targets due to the easier nature of access; SCUBA diving allows for in situ delicate human interactions. Beyond the range of technical SCUBA (~150 m), the ability to achieve the same level of human dexterity using robotic systems becomes critically important. The deep ocean is navigated primarily by manned submersibles or remotely operated vehicles, which currently offer few options for delicate manipulation. Here we present results in developing a soft robotic manipulator for deep-sea biological sampling. This low-power glove controlled soft robot was designed with the future marine biologist in mind, where science can be conducted at a comparable or better means than via a human diver and at depths well beyond the limits of SCUBA. The technology relies on compliant materials that are matched with the soft and fragile nature of marine organisms, and uses seawater as the working fluid. Actuators are driven by a custom proportional-control hydraulic engine that requires less than 50 W of electrical power, making it suitable for battery-powered operation. A wearable glove master allows for intuitive control of the arm. The manipulator system has been successfully operated in depths exceeding 2300 m (3500 psi) and has been field-tested onboard a manned submersible and unmanned remotely operated vehicles. The design, development, testing, and field trials of the soft manipulator is placed in context with existing systems and we offer suggestions for future work based on these findings. PMID- 30283052 TI - Monitoring of microbial dynamics in a drinking water distribution system using the culture-free, user-friendly, MYcrobiota platform. AB - Drinking water utilities currently rely on a range of microbiological detection techniques to evaluate the quality of their drinking water (DW). However, microbiota profiling using culture-free 16S rRNA gene next-generation sequencing (NGS) provides an opportunity for improved monitoring of the microbial ecology and quality of DW. Here, we evaluated the utility of a previously validated microbiota profiling platform (MYcrobiota) to investigate the microbial dynamics of a full-scale, non-chlorinated DW distribution system (DWDS). In contrast to conventional methods, we observed spatial and temporal bacterial genus changes (expressed as operational taxonomic units - OTUs) within the DWDS. Further, a small subset of bacterial OTUs dominated with abundances that shifted across the length of the DWDS, and were particularly affected by a post-disinfection step. We also found seasonal variation in OTUs within the DWDS and that many OTUs could not be identified, even though MYcrobiota is specifically designed to reduce potential PCR sequencing artefacts. This suggests that our current knowledge about the microbial ecology of DW communities is limited. Our findings demonstrate that the user-friendly MYcrobiota platform facilitates culture-free, standardized microbial dynamics monitoring and has the capacity to facilitate the introduction of microbiota profiling into the management of drinking water quality. PMID- 30283053 TI - Rapid in situ synthesis of polymer-metal nanocomposite films in several seconds using a CO2 laser. AB - We demonstrate the rapid in situ synthesis of polymer-metal nanocomposite films using a CO2 laser at 10.6 MUm. The mechanism of our method is that the precursor of the metal nanoparticles, i.e., the metallic ions, is very rapidly reduced in the laser-heated polymer matrix without any reducing agent. Unlike other known laser-induced reduction methods using UV lasers, which produce radicals to promote reduction, the CO2 laser energy is mainly absorbed by the glass substrate, and the laser-heated substrate heats the polymer matrix through heat diffusion to promote reduction. The superiority of the use of CO2 lasers over nanosecond visible~UV lasers is also demonstrated in terms of the damage to the film. The developed method can be a new alternative to quickly synthesize a variety of polymer-metal nanocomposite films.

PMID- 30283056 TI - Antarctic marine ciliates under stress: superoxide dismutases from the psychrophilic Euplotes focardii are cold-active yet heat tolerant enzymes. AB - Oxidative stress is a particularly severe threat to Antarctic marine polar organisms because they are exposed to high dissolved oxygen and to intense UV radiation. This paper reports the features of three superoxide dismutases from the Antarctic psychrophilic ciliate Euplotes focardii that faces two environmental challenges, oxidative stress and low temperature. Two out of these are Cu,Zn superoxide dismutases (named Ef-SOD1a and Ef-SOD1b) and one belongs to the Mn-containing group (Ef-SOD2). Ef-SOD1s and Ef-SOD2 differ in their evolutionary history, expression and overall structural features. Ef-SOD1 genes are expressed at different levels, with Ef-SOD1b mRNA 20-fold higher at the ciliate optimal temperature of growth (4 degrees C). All Ef-SOD enzymes are active at 4 degrees C, consistent with the definition of cold-adapted enzymes. At the same time, they display temperatures of melting in the range 50-70 degrees C and retain residual activity after incubation at 65-75 degrees C. Supported by data of molecular dynamics simulation, we conclude that the E. focardii SODs combine cold activity, local molecular flexibility and thermo tolerance. PMID- 30283057 TI - Kidney-derived c-kit+ progenitor/stem cells contribute to podocyte recovery in a model of acute proteinuria. AB - Kidney-derived c-kit+ cells exhibit progenitor/stem cell properties and can regenerate epithelial tubular cells following ischemia-reperfusion injury in rats. We therefore investigated whether c-kit+ progenitor/stem cells contribute to podocyte repair in a rat model of acute proteinuria induced by puromycin aminonucleoside (PAN), the experimental prototype of human minimal change disease and early stages of focal and segmental glomerulosclerosis. We found that c-kit+ progenitor/stem cells accelerated kidney recovery by improving foot process effacement (foot process width was lower in c-kit group vs saline treated animals, P = 0.03). In particular, these cells engrafted in small quantity into tubules, vessels, and glomeruli, where they occasionally differentiated into podocyte-like cells. This effect was related to an up regulation of alpha-Actinin 4 and mTORC2-Rictor pathway. Activation of autophagy by c-kit+ progenitor/stem cells also contributed to kidney regeneration and intracellular homeostasis (autophagosomes and autophagolysosomes number and LC3A/B-I and LC3A/B-II expression were higher in the c-kit group vs saline treated animals, P = 0.0031 and P = 0.0009, respectively). Taken together, our findings suggest that kidney derived c-kit+ progenitor/stem cells exert reparative effects on glomerular disease processes through paracrine effects, to a lesser extent differentiation into podocyte-like cells and contribution to maintenance of podocyte cytoskeleton after injury. These findings have clinical implications for cell therapy of glomerular pathobiology. PMID- 30283058 TI - Voice-selective prediction alterations in nonclinical voice hearers. AB - Auditory verbal hallucinations (AVH) are a cardinal symptom of psychosis but also occur in 6-13% of the general population. Voice perception is thought to engage an internal forward model that generates predictions, preparing the auditory cortex for upcoming sensory feedback. Impaired processing of sensory feedback in vocalization seems to underlie the experience of AVH in psychosis, but whether this is the case in nonclinical voice hearers remains unclear. The current study used electroencephalography (EEG) to investigate whether and how hallucination predisposition (HP) modulates the internal forward model in response to self initiated tones and self-voices. Participants varying in HP (based on the Launay Slade Hallucination Scale) listened to self-generated and externally generated tones or self-voices. HP did not affect responses to self vs. externally generated tones. However, HP altered the processing of the self-generated voice: increased HP was associated with increased pre-stimulus alpha power and increased N1 response to the self-generated voice. HP did not affect the P2 response to voices. These findings confirm that both prediction and comparison of predicted and perceived feedback to a self-generated voice are altered in individuals with AVH predisposition. Specific alterations in the processing of self-generated vocalizations may establish a core feature of the psychosis continuum. PMID- 30283059 TI - Cationic clustering influences the phase behaviour of ionic liquids. AB - "Unlike charges attract, but like charges repel". This conventional wisdom has been recently challenged for ionic liquids. It could be shown that like-charged ions attract each other despite the powerful opposing electrostatic forces. In principle, cooperative hydrogen bonding between ions of like-charge can overcome the repulsive Coulomb interaction while pushing the limits of chemical bonding. The key challenge of this solvation phenomenon is to establish design principles for the efficient formation of clusters of like-charged ions in ionic liquids. This is realised here for a set of well-suited ionic liquids including the same hydrophobic anion but different cations all equipped with hydroxyethyl groups for possible H-bonding. The formation of H-bonded cationic clusters can be controlled by the delocalization of the positive charge on the cations. Strongly localized charge results in cation-anion interaction, delocalized charge leads to the formation of cationic clusters. For the first time we can show, that the cationic clusters influence the properties of ILs. ILs comprising these clusters can be supercooled and form glasses. Crystalline structures are obtained only, if the ILs are dominantly characterized by the attraction between opposite-charged ions resulting in conventional ion pairs. That may open a new path for controlling glass formation and crystallization. The glass temperatures and the phase transitions of the ILs are observed by differential scanning calorimetry (DSC) and infrared (IR) spectroscopy. PMID- 30283060 TI - Turning a native or corroded Mg alloy surface into an anti-corrosion coating in excited CO2. AB - Despite their energy-efficient merits as promising light-weight structural materials, magnesium (Mg) based alloys suffer from inadequate corrosion resistance. One primary reason is that the native surface film on Mg formed in air mainly consists of Mg(OH)2 and MgO, which is porous and unprotective, especially in humid environments. Here, we demonstrate an environmentally benign method to grow a protective film on the surface of Mg/Mg alloy samples at room temperature, via a direct reaction of already-existing surface film with excited CO2. Moreover, for samples that have been corroded obviously on surface, the corrosion products can be converted directly to create a new protective surface. Mechanical tests show that compared with untreated samples, the protective layer can elevate the yield stress, suppress plastic instability and prolong compressive strains without peeling off from the metal surface. This environmentally friendly surface treatment method is promising to protect Mg alloys, including those already-corroded on the surface. PMID- 30283061 TI - Longitudinal changes in physical capacity from adolescence to middle age in men and women. AB - The aim was to investigate how physical capacity changes from adolescence through early adulthood to middle age with focus on early aging. The aim was also to study if physical capacity in middle age could be predicted by factors in adolescence or early adulthood. A cohort of men and women in Sweden (SPAF-1958, n = 425) have been followed for 36 years, at 16, 34, and 52 years of age. The study includes, among other variables, objective measures of physical capacity. At age 52, 50% of the original cohort participated in exercise testing. Physical capacity increased from 16 to 34 years. From 34 to 52 years, physical capacity decreased in both genders by 15-20% in all but one test. Physical capacity at 16 and 34 years of age were better predictors of physical capacity at age 52 than body dimensions, school grades and life style factors. In conclusion, present data confirm earlier cross-sectional studies regarding the decrease in aerobic capacity and muscular strength during the early ageing period in both genders. The study has also generated novel data that show a smaller decline in muscular endurance than previously reported. Finally, physical capacity is fairly stable from adolescence to middle age.

AB - Water vapor (WV) is the most variable greenhouse gas in the troposphere, therefore investigation of its spatio-temporal distribution and motion is of great importance in meteorology and climatology studies. Here, we suggest a new strategy for augmenting integrated water vapor (IWV) estimations using both remote sensing satellites and global positioning system (GPS) tropospheric path delays. The strategy is based first on the ability to estimate METEOSAT-10 7.3 um WV pixel values by extracting the mathematical dependency between the IWV amount calculated from GPS zenith wet delays (ZWD) and the METEOSAT-10 data. We then use the surface temperature differences between ground station measurements and METEOSAT-10 10.8 um infra-red (IR) channel to identify spatio-temporal cloud distribution structures. As a last stage, the identified cloud features are mapped into the GPS-IWV distribution map when preforming the interpolation between adjusted GPS station inside the network. The suggested approach improves the accuracy of estimated regional IWV maps, in comparison with radiosonde data, thus enables to obtain the total water amount at the atmosphere, both in the form of clouds and vapor. Mean and root mean square (RMS) difference between the GPS IWV estimations, using the spatio-temporal clouds distribution, and radiosonde data are reduced from 1.77 and 2.81 kg/m2 to 0.74 and 2.04 kg/m2, respectively. Furthermore, by improving the accuracy of the estimated regional IWV maps distribution it is possible to increase the accuracy of regional Numerical Weather Prediction (NWP) platforms. PMID- 30283065 TI - Towards improvement in prediction of iodine value in edible oil system based on chemometric analysis of portable vibrational spectroscopic data. AB - Iodine value (IV) is a significant parameter to illustrate the quality of edible oil. In this study, three portable spectroscopy devices were employed to determine IV in mixed edible oil system, a new Micro-Electro-Mechanical-System (MEMS) Fourier Transform Infrared Spectrometer (MEMS-FTIR), a MicroNIRTM1700 and an i-Raman Plus-785S. Quantitative model was built by Partial least squares (PLS) regression model and four variable selection methods were applied before PLS model, which are Monte Carlo uninformative variables elimination (MCUVE), competitive reweighted sampling (CARS), bootstrapping soft shrinkage approach (BOSS) and variable combination population analysis (VCPA). The coefficient of determination (R2), and the root mean square error prediction (RMSEP) were used as indicators for the predictability of the PLS models. In MicroNIRTM1700 dataset, MCUVE gave the lowest RMSEP (2.3440), in MEMS-FTIR dataset, CARS showed the best performance with RMSEP (2.2185), in i-Raman Plus-785S dataset, BOSS gave the lowest RMSEP (2.5058). They all had great improvements than full spectrum PLS model. Four variable selection methods take a smaller number of variables and perform significant superiority in prediction accuracy. It was demonstrated that three new portable instruments would be suitable for the on-site determination of edible oil quality in infrared and Raman field.

AB - Different types of pores ubiquitously form in cell membranes, leading to various types of cell death that profoundly influence the fate of inflammation and the disease status. However, these pores have never truly been visualized to date. Atomic force microscopy (AFM), which is emerging as a powerful tool to analyze the mechanical properties of biomolecules and cells, is actually an excellent imaging platform that allows biological samples to be visualized by probing surface roughness at the level of atomic resolution. Here, membrane pore structures were clearly visualized using AFM. This visualization not only describes the aperture and depth of the pore complexes but also highlights differences among the pores formed by perforin and gasdermins in tumor cell membranes and by complement in immune cell membranes. Additionally, this type of visualization also reveals the dynamic process of pore formation, fusion, and repair.

AB - MacNaughton et al. recently published an article entitled, "Energy savings, emissions reductions, and health co-benefits of the green building movement" in which they claim to calculate the environmental co-benefits associated with the (assumed) reduced energy use of green buildings. They consider only LEED (Leadership in Energy and Environmental Design) commercial buildings and make two fundamental assumptions: (1) that each LEED building, year after year, achieves the energy savings projected by its design team, and (2) that the fuel mix of LEED buildings is the same as the average mix for other buildings in the same geographic region.Here we show that these assumptions are not supported by data. Numerous studies have shown that buildings, on average, use significantly more energy than projected by design simulations. Furthermore, a decade of research suggests that LEED-certified buildings, on average, achieve little or no primary energy savings relative to other similar buildings. In addition, evidence suggests that any reduction in site energy is typically achieved through increased electric use and corresponding off-site energy loss. The environmental benefits of LEED buildings calculated by MacNaughton et al. have dubious value because they are based on assumptions that are inconsistent with measured LEED building energy performance.

AB - The basidiomycete Melampsora larici-populina causes poplar rust disease by invading leaf tissues and secreting effector proteins through specialized infection structures known as haustoria. The mechanisms by which rust effectors promote pathogen virulence are poorly understood. The present study characterized Mlp124478, a candidate effector of M. larici-populina. We used the models Arabidopsis thaliana and Nicotiana benthamiana to investigate the function of Mlp124478 in plant cells. We established that Mlp124478 accumulates in the nucleus and nucleolus, however its nucleolar accumulation is not required to promote growth of the oomycete pathogen Hyaloperonospora arabidopsidis. Stable constitutive expression of Mlp124478 in A. thaliana repressed the expression of genes involved in immune responses, and also altered leaf morphology by increasing the waviness of rosette leaves. Chip-PCR experiments showed that Mlp124478 associats'e with the TGA1a-binding DNA sequence. Our results suggest that Mlp124478 exerts a virulence activity and binds the TGA1a promoter to suppress genes induced in response to pathogen infection.

AB - Environmental noise from sources such as traffic, airports, and oil and gas (O&G) operations is associated with nuisance and health concerns. Smartphones with external microphones have been recommended for environmental noise monitoring and may be useful tools for citizen science, but are not validated against reference methods. We evaluated laboratory performance of three smartphone/application (app) configurations recommended for environmental noise measurement. Two smartphone/app configurations were also compared to a reference sampler, a type 1 sound level meter (SLM) at ten outdoor sites with traffic, airport, and O&G noise. To evaluate performance, we compared the mean squared error, variance, bias, and Krippendorff's Alpha by smartphone/app combination and testing location for both audible (A-weighted) and low-frequency (C-weighted) noise. We observed that laboratory measurements were in strong agreement with a reference sampler. The field A-weighted noise level results had strong agreement with the SLM at several outdoor sites, but our C-weighted noise results ranged from moderate to substantial agreement. For our tested configurations, we find that smartphones with external microphones are reliable proxies for measuring A- and C-weighted noise in a laboratory setting. Outdoor performance depends on noise source type, weighting, and precision and accuracy needs of the investigation. PMID- 30283069 TI - Heat waves in South Korea: differences of heat wave characteristics by thermal indices. AB - Heat wave warning systems and related research define heat waves using various indices and there exists no standard definition for a heat wave. Despite various weather forecast services for heat stress in South Korea, it is unclear how different thermal indices affect the designation of heat waves and health effect estimates. We aimed to analyze trends of heat wave characteristics and mortality associations using various criteria for the warm season (June-September) in 2011 5 for the most populated two cities in South Korea, Seoul and Busan. Hourly weather monitoring data and daily mortality data in each city were obtained. The following indices were estimated to define heat waves: air temperature, heat index (HI), humidex, apparent temperature (AT), effective temperature (ET), and wet-bulb globe temperature (WBGT). The thresholds of each index for heat wave definitions were obtained by statistical distribution (95th percentiles) and minimum mortality temperature (MMT). Thermal indices showed clustering of accumulation of excess heat above thresholds for northeast regions in the cities while air temperature showed it for central regions. Compared to 95th percentiles, the MMTs resulted 14 times longer heat wave days for thermal indices except for air temperature. When MMTs were used, nine times larger excess mortality from heat waves occurred for all indices compared to that from heat waves defined by the 95th percentiles. The thermal indices with the highest association between heat and mortality varied between the two cities: air temperature for Seoul and WBGT for Busan. Heat wave warnings should be based on a thorough comparison of how different heat wave criteria will affect the public health impact of heat wave warnings in terms of identifying a heat wave and degree of health impacts due to it.

AB - A broad range of dynamic metasurfaces has been developed for manipulating the intensity, phase and wavefront of electromagnetic radiation from microwaves to optical frequencies. However, most of these metasurfaces operate in single-input output state. Here, we experimentally demonstrate a reconfigurable MEMS Fano resonant metasurface possessing multiple-input-output (MIO) states that performs logic operations with two independently controlled electrical inputs and an optical readout at terahertz frequencies. The far-field behaviour of Fano resonance exhibits XOR and XNOR operations, while the near-field resonant confinement enables the NAND operation. The MIO configuration resembling hysteresis-type closed-loop behaviour is realized through inducing electromechanically tuneable out-of-plane anisotropy in the near-field coupling of constituent resonator structures. The XOR metamaterial gate possesses potential applications in cryptographically secured terahertz wireless communication networks. Furthermore, the MIO features could lay the foundation for the realization of programmable and randomly accessible metamaterials with enhanced electro-optical performance across terahertz, infrared and optical frequencies. PMID- 30283071 TI - Impaired tumor growth and angiogenesis in mice heterozygous for Vegfr2 (Flk1). AB - VEGF signaling through its tyrosine kinase receptor, VEGFR2 (FLK1), is critical for tumor angiogenesis. Previous studies have identified a critical gene dosage effect of VegfA in embryonic development and vessel homeostasis, neovascularization, and tumor growth, and potent inhibitors of VEGFR2 have been used to treat a variety of cancers. Inhibition of FGFR signaling has also been considered as an antiangiogenic approach to treat a variety of cancers. Inhibition of VEGFR2 with neutralizing antibodies or with pharmacological inhibitors of the VEGFR tyrosine kinase domain has at least short-term efficacy with some cancers; however, also affects vessel homeostasis, leading to adverse complications. We investigate gene dosage effects of Vegfr2, Fgfr1, and Fgfr2 in three independent mouse models of tumorigenesis: two-stage skin chemical carcinogenesis, and sub-cutaneous transplantation of B16F0 melanoma and Lewis Lung Carcinoma (LLC). Mice heterozygous for Vegfr2 display profound defects in supporting tumor growth and angiogenesis. Unexpectedly, additional deletion of endothelial Fgfr1 and Fgfr2 in Vegfr2 heterozygous mice shows similar tumor growth and angiogenesis as the Vegfr2 heterozygous mice. Notably, hematopoietic deletion of two alleles of Vegfr2 had minimal impact on tumor growth, with little effect on angiogenesis, reinforcing the importance of endothelial Vegfr2 heterozygosity. These studies reveal previously unrecognized Vegfr2 gene dosage effects in tumor angiogenesis and a lack of synergy between VEGFR2 and endothelial FGFR1/2 signaling during tumor growth. PMID- 30283072 TI - Spatial and temporal characteristics of temperature effects on cardiovascular disease in Southern China using the Empirical Mode Decomposition method. AB - Until now, few studies have analyzed the effects of temperature on cardiovascular disease (CVD) death at different time points. In this study, we chose 9 different cities in the subtropical and tropical areas of China and analyzed the correlation between temperature at different time points and CVD mortality. We completed this study in two steps. First, we analyzed different time trend decomposition data related to CVD mortality in different populations within the 9 selected cities using empirical mode decomposition (EMD). Second, we created a regression fitting analysis of CVD mortality and temperatures at different time periods. The results showed that the CVD mortality of subtropical and tropical areas in southern Chinese cities represented spatial heterogeneity. The CVD mortality rates in Beihai, Hefei and Nanning showed rising trends, whereas the CVD mortality rates in Haikou, Guilin and Changde appeared to be decreasing. At the daily, seasonal and year time scales, low temperatures were negatively correlated with CVD mortality. Other than at the daily time scale, high temperatures did not significantly influence CVD mortality. This article will help to develop appropriate measures to reduce temperature-related mortality risk in different populations within the subtropical and tropical regions of China.

PMID- 30283073 TI - A Comparative Study of Hummingbirds and Chickens Provides Mechanistic Insight on the Histidine Containing Dipeptide Role in Skeletal Muscle Metabolism. AB - Histidine containing dipeptides (HCDs) have numerous ergogenic and therapeutic properties, but their primary role in skeletal muscle remains unclear. Potential functions include pH regulation, protection against reactive oxygen/nitrogen species, or Ca2+ regulation. In recognition of the challenge of isolating physiological processes in-vivo, we employed a comparative physiology approach to investigate the primary mechanism of HCD action in skeletal muscle. We selected two avian species (i.e., hummingbirds and chickens), who represented the extremes of the physiological processes in which HCDs are likely to function. Our findings indicate that HCDs are non-essential to the development of highly oxidative and contractile muscle, given their very low content in hummingbird skeletal tissue. In contrast, their abundance in the glycolytic chicken muscle, indicate that they are important in anaerobic bioenergetics as pH regulators. This evidence provides new insights on the HCD role in skeletal muscle, which could inform widespread interventions, from health to elite performance. PMID- 30283076 TI - Impact of overweight, obesity and severe obesity on life expectancy of Australian adults. AB - BACKGROUND/OBJECTIVES: Adult obesity has been shown to substantially heighten the risk of adverse health outcomes but its impact on life expectancy (LE) has not been quantified in Australia. Our aim is to estimate reductions in LE and years of life lost (YLL) associated with overweight and obesity, relative to those at a healthy weight for Australian adults aged 20-69 years. SUBJECTS/METHODS: We used a microsimulation model of obesity progression in Australia that integrates annual change in BMI based on age and sex, with Australian life-table data and published relative risk of all-cause mortality for different BMI categories. Remaining LE and YLL compared to healthy weight were estimated using 10-year cohorts, by sex. A nationally representative sample of 12,091 adults aged 20-69 from the 2014/15 Australian National Health Survey were used to represent the input population of 14.9 million. RESULTS: Estimated remaining years of LE for healthy weight men and women aged 20-29 years was approximately 57.0 (95% CI 56.7 57.4) and 59.7 (95% CI 59.4-60.0) years, respectively. YLL associated with being overweight at baseline was approximately 3.3 years. For those obese and severely obese the loss in LE was predicted to be 5.6-7.6 years and 8.1-10.3 years for men and women aged 20-29 years, respectively. Across men and women, excess BMI in the adult population is responsible for approximately 36.3 million YLLs. Men stand to lose 27.7% more life years compared to women. CONCLUSIONS: Overweight and obesity is associated with premature mortality at all ages, for both men and women. Adults aged 20-39 years with severe obesity will experience the largest YLL, relative to healthy weight. More needs to be done in Australia to establish a coherent, sustained, cost-effective strategy to prevent overweight and obesity, particularly for men in early adulthood. PMID- 30283077 TI - Ascorbic acid inhibits visceral obesity and nonalcoholic fatty liver disease by activating peroxisome proliferator-activated receptor alpha in high-fat-diet-fed C57BL/6J mice. AB - BACKGROUND/OBJECTIVES: Ascorbic acid is a known cofactor in the biosynthesis of carnitine, a molecule that has an obligatory role in fatty acid oxidation. Our previous studies have demonstrated that obesity is regulated effectively through peroxisome proliferator-activated receptor alpha (PPARalpha)-mediated fatty acid beta-oxidation. Thus, this study aimed to determine whether ascorbic acid can inhibit obesity and nonalcoholic fatty liver disease (NAFLD) in part through the actions of PPARalpha. DESIGN: After C57BL/6J mice received a low-fat diet (LFD, 10% kcal fat), a high-fat diet (HFD, 45% kcal fat), or the same HFD supplemented with ascorbic acid (1% w/w) (HFD-AA) for 15 weeks, variables and determinants of visceral obesity and NAFLD were examined using metabolic measurements, histology, and gene expression. RESULTS: Compared to HFD-fed obese mice, administration of HFD-AA to obese mice reduced body weight gain, visceral adipose tissue mass, and visceral adipocyte size without affecting food consumption profiles. Concomitantly, circulating ascorbic acid concentrations were significantly higher in HFD-AA mice than in HFD mice. Ascorbic acid supplementation increased the mRNA levels of PPARalpha and its target enzymes involved in fatty acid beta-oxidation in visceral adipose tissues. Consistent with the effects of ascorbic acid on visceral obesity, ascorbic acid not only inhibited hepatic steatosis but also increased the mRNA levels of PPARalpha-dependent fatty acid beta-oxidation genes in livers. Similarly, hepatic inflammation, fibrosis, and apoptosis were also decreased during ascorbic acid-induced inhibition of visceral obesity. In addition, serum levels of alanine aminotransferase, aspartate aminotransferase, total cholesterol, and LDL cholesterol were lower in HFD-AA-fed mice than in those of HFD-fed mice. CONCLUSIONS: These results suggest that ascorbic acid seems to suppress HFD-induced visceral obesity and NAFLD in part through the activation of PPARalpha. PMID- 30283078 TI - Working toward precision medicine approaches to treat severe obesity in adolescents: report of an NIH workshop. AB - Adolescent severe obesity is a prevalent, chronic, and serious disease with few effective and safe treatment options. To address this issue, a National Institutes of Health-sponsored workshop entitled "Developing Precision Medicine Approaches to the Treatment of Severe Obesity in Adolescents," was convened, bringing together a multidisciplinary group of experts to review the current state of the science and identify (1) what is known regarding the epidemiology and biopsychosocial determinants of severe obesity in adolescents, (2) what is known regarding effectiveness of treatments for severe obesity in adolescents and predictors of response, and (3) gaps and opportunities for future research to develop more effective and targeted treatments for adolescents with severe obesity. Major topical areas discussed at the workshop included: appropriate BMI metrics, valid measures of phenotypes and predictors, mechanisms associated with the development of severe obesity, novel treatments informed by biologically and psychosocially plausible mechanisms, biopsychosocial phenotypes predicting treatment response, standardization of outcome measures and results reporting in research, and improving clinical care. Substantial gaps in knowledge were identified regarding the basic behavioral, psychosocial, and biological mechanisms driving the development of severe obesity and the influence of these factors on treatment response. Additional exploratory and observational studies are needed to better understand the heterogeneous etiology of severe obesity and explain the high degree of variability observed with interventions. Tailored treatment strategies that may be developed by achieving a better understanding of individual differences in genetic endowment, clinical, metabolic, psychological, and behavioral phenotypes, and response to environmental exposures need to be tested. It is anticipated that these recommendations for future research, including strategies to enhance methodological rigor, will advance precision medicine approaches to treat severe obesity in adolescents more effectively. PMID- 30283079 TI - Sugar-sweetened beverage intake and relative weight gain among South African adults living in resource-poor communities: longitudinal data from the STOP-SA study. AB - OBJECTIVES: This study examines the prospective association between sugar sweetened beverages (SSB) consumption and change in body weight over a 4-5-year period in a socio-economically disadvantaged South African population. METHODS: This is a longitudinal study involving 800 adults (212 men, 588 women); 247 from the original METS (Modelling the Epidemiological Transition Study) cohort (N = 504) and 553 of the original 949 members of the PURE (Prospective Urban and Rural Epidemiology) Study. Both cohorts were drawn from low-income, socio-economically disadvantaged communities. Mean follow-up duration and age were 4.5 (SD 0.45) and 50.0 (SD 11.8) years, respectively. Harmonised measurements included body mass index, self-reported moderate-to-vigorous physical activity, and intake of meat, snacks and 'take-aways', fruits and vegetables and SSB (in servings/week). Multivariate logistic regression models were developed to determine the extent to which SSB consumption predicted relative weight gain, after controlling for potential confounders and known predictors. RESULTS: Nearly a third (29%) of participants had a relative weight change >=5.0%; higher in the non-obese compared to the obese group (32% vs. 25%; p = 0.026). The average SSB consumption was 9.9 servings/week and was higher in the food insecure compared to the food secure group (11.5 vs. 9.0 servings/week; p = 0.006); but there were no differences between women and men (10.3 vs. 9.1 servings/week; p = 0.054). Mean SSB consumption was higher in the group who gained >=5% weight compared to those who did not (11.0 vs. 8.7; p = 0.004). After adjustment, SSB consumption of 10 or more servings/week was associated with a 50% greater odds of gaining at least 5% body weight (AOR: 1.50, 95% CI (1.05-2.18)). CONCLUSION: These results show that higher intake of SSB predicts weight gain in a sample of South Africans drawn from low-income settings. Comprehensive, population-wide interventions are needed to reduce SSB consumption in these settings. PMID- 30283080 TI - Fluorescent blood-brain barrier tracing shows intact leptin transport in obese mice. AB - BACKGROUND/OBJECTIVES: Individuals carrying loss-of-function gene mutations for the adipocyte hormone leptin are morbidly obese, but respond favorably to replacement therapy. Recombinant leptin is however largely ineffective for the vast majority of obese individuals due to leptin resistance. One theory underlying leptin resistance is impaired leptin transport across the blood-brain barrier (BBB). Here, we aim to gain new insights into the mechanisms of leptin BBB transport, and its role in leptin resistance. METHODS: We developed a novel tool for visualizing leptin transport using infrared fluorescently labeled leptin, combined with tissue clearing and light-sheet fluorescence microscopy. We corroborated these data using western blotting. RESULTS: Using 3D whole brain imaging, we display comparable leptin accumulation in circumventricular organs of lean and obese mice, predominantly in the choroid plexus (CP). Protein quantification revealed comparable leptin levels in microdissected mediobasal hypothalami (MBH) of lean and obese mice (p = 0.99). We further found increased leptin receptor expression in the CP (p = 0.025, p = 0.0002) and a trend toward elevated leptin protein levels in the MBH (p = 0.17, p = 0.078) of obese mice undergoing weight loss interventions by calorie restriction or exendin-4 treatment. CONCLUSIONS: Overall, our findings suggest a crucial role for the CP in controlling the transport of leptin into the cerebrospinal fluid and from there to target areas such as the MBH, potentially mediated via the leptin receptor. Similar leptin levels in circumventricular organs and the MBH of lean and obese mice further suggest intact leptin BBB transport in leptin resistant mice. PMID- 30283081 TI - Mammalian nucleolar protein DCAF13 is essential for ovarian follicle maintenance and oocyte growth by mediating rRNA processing. AB - During mammalian oocyte growth, chromatin configuration transition from the nonsurrounded nucleolus (NSN) to surrounded nucleolus (SN) type plays a key role in the regulation of gene expression and acquisition of meiotic and developmental competence by the oocyte. Nonetheless, the mechanism underlying chromatin configuration maturation in oocytes is poorly understood. Here we show that nucleolar protein DCAF13 is an important component of the ribosomal RNA (rRNA) processing complex and is essential for oocyte NSN-SN transition in mice. A conditional knockout of Dcaf13 in oocytes led to the arrest of oocyte development in the NSN configuration, follicular atresia, premature ovarian failure, and female sterility. The DCAF13 deficiency resulted in pre-rRNA accumulation in oocytes, whereas the total mRNA level was not altered. Further exploration showed that DCAF13 participated in the 18S rRNA processing in growing oocytes. The lack of 18S rRNA because of DCAF13 deletion caused a ribosome assembly disorder and then reduced global protein synthesis. DCAF13 interacted with a protein of the core box C/D ribonucleoprotein, fibrillarin, i.e., a factor of early pre-rRNA processing. When fibrillarin was knocked down in the oocytes from primary follicles, follicle development was inhibited as well, indicating that an rRNA processing defect in the oocyte indeed stunts chromatin configuration transition and follicle development. Taken together, these results elucidated the in vivo function of novel nucleolar protein DCAF13 in maintaining mammalian oogenesis. PMID- 30283082 TI - Hypoxia-induced autophagy of stellate cells inhibits expression and secretion of lumican into microenvironment of pancreatic ductal adenocarcinoma. AB - Lumican is secreted by pancreatic stellate cells and inhibits cancer progression. Extracellular lumican inhibits cancer cell replication and restrains growth of early-stage pancreatic adenocarcinoma (PDAC) such that patients with tumors containing stromal lumican experience a three-fold longer survival after treatment. In the present study, patient tumor tissues, ex-vivo cultures of patient-derived xenografts (PDX), PDAC stellate and tumor cells were used to investigate whether hypoxia (1% O2) within the tumor microenvironment influences stromal lumican expression and secretion. We observed that hypoxia significantly reduced lumican expression and secretion from pancreatic stellate cells, but not cancer cells. Although hypoxia enhanced lactate dehydrogenase A (LDHA) expression and lactate secretion from all cells, neither hypoxia-induced nor exogenous lactate influenced lumican expression. Autophagy was induced by hypoxia in ex vivo cultures of PDX and pancreatic stellate cells, but not cancer cells cultured in 2D. Autophagic flux inhibitors, bafilomycin A1, chloroquine diphosphate salt, and ammonium chloride prevented hypoxia-mediated reduction in lumican expression in stellate cells. Furthermore, inhibition of AMP-regulated protein kinase (AMPK) phosphorylation or hypoxia-inducible factor (HIF)-1alpha expression within hypoxic stellate cells restored lumican expression levels. Hypoxia did not affect lumican mRNA expression, indicating that hypoxia-induced reduction of lumican occurs post-transcriptionally; in addition, AMPK inhibition prevented hypoxia reduced phosphorylation of the mTOR/p70S6K/4EBP signaling pathway, a key contributor to protein synthesis. Taken together, these findings demonstrate that hypoxia reduces stromal lumican in PDAC through autophagy-mediated degradation and reduction in protein synthesis within pancreatic cancer stellate cells. PMID- 30283083 TI - Synthesis and characterization of monodispersed water dispersible Fe3O4 nanoparticles and in vitro studies on human breast carcinoma cell line under hyperthermia condition. AB - Monodispersed Fe3O4 magnetic nanoparticles (MNPs) having size of 7 nm have been prepared from iron oleate and made water dispersible by functionalization for biomedical applications. Three different reactions employing thioglycolic acid, aspartic acid and aminophosphonate were performed on oleic acid coated Fe3O4. In order to achieve a control on particle size, the pristine nanoparticles were heated in presence of ferric oleate which led to increase in size from 7 to 11 nm. Reaction parameters such as rate of heating, reaction temperature and duration of heating have been studied. Shape of particles was found to change from spherical to cuboid. The cuboid shape in turn enhances magneto-crystalline anisotropy (Ku). Heating efficacy of these nanoparticles for hyperthermia was also evaluated for different shapes and sizes. We demonstrate heat generation from these MNPs for hyperthermia application under alternating current (AC) magnetic field and optimized heating efficiency by controlling morphology of particles. We have also studied intra-cellular uptake and localization of nanoparticles and cytotoxicity under AC magnetic field in human breast carcinoma cell line. PMID- 30283084 TI - Impact of an infectious diseases specialist-led antimicrobial stewardship programmes on antibiotic use and antimicrobial resistance in a large Korean hospital. AB - The aim of this study was to evaluate the impact of an infectious diseases specialist (IDS)-led antimicrobial stewardship programmes (ASPs) in a large Korean hospital. An interrupted time series analysis assessing the trends in antibiotic use and antimicrobial resistance rate of major pathogens between September 2015 and August 2017 was performed in an 859-bed university-affiliated hospital in Korea. The restrictive measure for designated antibiotics led by an IDS reduced carbapenems usage by -4.57 days of therapy (DOT)/1,000 patient-days per month in general wards (GWs) (95% confidence interval [CI], -6.69 to -2.46; P < 0.001), and by -41.50 DOT/1,000 patient-days per month in intensive care units (ICUs) (95% CI, -57.91 to -25.10; P < 0.001). Similarly, glycopeptides usage decreased by -2.61 DOT/1,000 patient-days per month in GWs (95% CI, -4.43 to 0.79; P = 0.007), and -27.41 DOT/1,000 patient-days per month in ICUs (95% CI, 47.03 to -7.79; P = 0.009). Use of 3rd generation cephalosporins, beta lactam/beta-lactamase inhibitors, and fluoroquinolones in GWs showed change comparable with that of carbapenems or glycopeptides use. Furthermore, trends of antimicrobial resistance rate of Staphylococcus aureus to gentamicin in GWs, Staphylococcus aureus to ciprofloxacin and oxacillin in ICUs, and Pseudomonas aeruginosa to imipenem in ICUs decreased in slope in the intervention period. The in-hospital mortality rate per 1,000 patient-days among ICU patients remained stable between the pre-intervention and intervention periods. In conclusion, an IDS-led ASPs could enact a meaningful reduction in antibiotic use, and a decrease in antibiotic resistance rate, without changing mortality rates in a large Korean hospital. PMID- 30283085 TI - Dianhydrogalactitol induces replication-dependent DNA damage in tumor cells preferentially resolved by homologous recombination. AB - 1,2:5,6-Dianhydrogalactitol (DAG) is a bifunctional DNA-targeting agent causing N7-guanine alkylation and inter-strand DNA crosslinks currently in clinical trial for treatment of glioblastoma. While preclinical studies and clinical trials have demonstrated antitumor activity of DAG in a variety of malignancies, understanding the molecular mechanisms underlying DAG-induced cytotoxicity is essential for proper clinical qualification. Using non-small cell lung cancer (NSCLC) as a model system, we show that DAG-induced cytotoxicity materializes when cells enter S phase with unrepaired N7-guanine DNA crosslinks. In S phase, DAG-mediated DNA crosslink lesions translated into replication-dependent DNA double-strand breaks (DSBs) that subsequently triggered irreversible cell cycle arrest and loss of viability. DAG-treated NSCLC cells attempt to repair the DSBs by homologous recombination (HR) and inhibition of the HR repair pathway sensitized NSCLC cells to DAG-induced DNA damage. Accordingly, our work describes a molecular mechanism behind N7-guanine crosslink-induced cytotoxicity in cancer cells and provides a rationale for using DAG analogs to treat HR-deficient tumors. PMID- 30283086 TI - CCAAT/enhancer-binding protein-beta functions as a negative regulator of Wnt/beta catenin signaling through activation of AXIN1 gene expression. AB - Axin1, a concentration-limiting component of the beta-catenin destruction complex, negatively regulates the Wnt/beta-catenin pathway. Axin1 concentration is reported to be regulated by proteasomal degradation; however, its transcriptional regulation has not yet been reported. Here, we demonstrated that CCAAT/enhancer-binding protein-beta (C/EBP-beta) activates axis inhibition protein 1 (AXIN1) gene expression, thereby attenuating Wnt/beta-catenin signaling. C/EBP-beta interacted with cis-regulatory element for C/EBP-beta in the 5'-upstream sequences of the AXIN1 gene and increased AXIN1 promoter activity. Functional analysis using Drosophila and zebrafish models established that C/EBP-beta negatively regulates the Wnt/beta-catenin pathway. Small-molecule based up-regulation of C/EBP-beta induces AXIN1 gene expression and down regulates the intracellular beta-catenin level, thereby inhibiting hepatoma cell growth. Thus, our findings provide a unique mechanistic insight into the regulation of Axin homeostasis and present a novel strategy for the development of anticancer therapeutics targeting Wnt/beta-catenin signaling. PMID- 30283087 TI - MR imaging of subaortic and retroesophageal anomalous courses of the left brachiocephalic vein in the fetus. AB - The purpose of this study was to report fetal cases of subaortic and retroesophageal anomalous courses of the left brachiocephalic vein (LBCV) evaluated by fetal cardiac magnetic resonance imaging (MRI). A retrospective review of 7282 fetal cardiac MRI from June 2006 to March 2017, nine cases of anomalous courses of the LBCV were correctly diagnosed by fetal cardiac MRI, one case of abnormal subaortic left brachiocephalic vein (ASLBV) missed by fetal MRI was identified postnatally during further imaging of the TOF. The diagnosis was confirmed postnatally by cardiac CT/MRI. An ASLBV was found in 8 cases, a retroesophageal LBCV was found in 2 additional cases with right aortic arch and aberrant left subclavian artery. 3 of 8 ASLBV cases were with a right aortic arch, 4 ASLBV cases had additional cardiovascular anomalies with one case isolated. 7 of 8 ASLBV and 2 retroesophageal LBCV were correctly diagnosed by fetal cardiac MRI; however fetal cardiac MRI missed 2 cases of associated pulmonary atresia (PA). Prenatal echocardiography (echo) correctly diagnosed five ASLBV and one retroesophageal LBCV as well as associated intracardiac anomalies. Fetal cardiac MRI can be a useful adjunct in the identification of subaortic and retroesophageal anomalous courses of the LBCV prenatally. PMID- 30283088 TI - Ten-year incidence of hypertension in a Swiss population-based sample Incidence of hypertension in Switzerland. AB - Few studies assessed incidence and determinants of hypertension. We assessed the incidence and determinants of hypertension in a cohort of healthy adults aged 35 75 years living in Lausanne, Switzerland. Baseline data were collected from 2003 to 2006. Follow-ups were conducted in 2009-2012 and 2014-2017. Incident hypertension, defined as a systolic BP >=140 mm Hg or a diastolic BP >=90 mm Hg or anti-hypertensive medication, was assessed at 1) second follow-up only; 2) first and/or second follow-up. After 10.9 years, incident hypertension was 26.8% (analysis 1, N = 3299) and 30.3% (analysis 2, N = 3728). After multivariate adjustment, the variables associated with increased hypertension incidence were male gender [incident-rate ratio (IRR) and (95% confidence interval)]: 1.20 (1.07 1.35) and 1.24 (1.13-1.37) for analyses 1 and 2, respectively; increasing age (p for trend < 0.001) and body mass index (p for trend < 0.001) and history of cardiovascular disease (CVD). Being physically active was negatively associated with incident hypertension: 0.88 (0.78-0.98) and 0.92 (0.83-1.01) for analyses 1 and 2, respectively. Except for male gender, these associations remained after adjusting for baseline BP levels, with incident rate ratios for physical activity of 0.86 (0.77-0.96) and 0.91 (0.83-0.99) for analyses 1 and 2, respectively. No association was found for education, alcohol consumption or smoking status. We conclude that over 10.9 years, between 1/4 and 1/3 of the Swiss population aged 35-75 developed hypertension. Male gender, history of CVD, increasing age and higher BMI increase the risk of hypertension, while being physically active reduces the risk. PMID- 30283090 TI - Disparities in the impact of overweight on hypertension among Asians: a Japanese and Thai population-based study. AB - The divergence in cardiovascular disease risk among Asian countries may be related to differences in economics, lifestyles, and cultural backgrounds. We examined the differential association of overweight and hypertension between the high- and middle-income Asian countries, namely Japan and Thailand and extended to compare other cardiovascular risk factors between these two countries, using the data sets from the annual health examinations conducted in 127,152 Japanese (mean age, 41.5 +/- 11.1 years; mean body mass index [BMI], 22.4 +/- 3.4 kg/m2) and 4243 Thai (mean age, 47.9 +/- 10.7 years: mean BMI, 24.0 +/- 3.7 kg/m2) aged over 18 years with no history of hypertension treatment. Hypertension was diagnosed as office SBP >= 130 mmHg and/or office DBP >= 80 mmHg. Overweight was defined as BMI >= 25 kg/m2. The analysis using the direct standardization method showed a lower prevalence of hypertension in the Japanese than in the Thai population (31.8% vs. 57.3%, P < 0.001). The Japanese population had higher estimated glomerular filtration rate and lower cholesterol level and BMI than in the Thai population (all P < 0.001). The association between overweight and hypertension was observed in both populations regardless of age and sex (all P < 0.05). In the analysis stratified by age and sex, the association between overweight and the presence of hypertension was more prominent in the Japanese population aged <50 years in both sexes compared with the Thai population (all P for interaction < 0.001). These results confirmed the differential impact of overweight on hypertension between the high- and middle-income countries even in the similar regions of Asia. PMID- 30283089 TI - A gender-specific association of the polymorphism Ile197Met in the kininogen 1 gene with plasma irbesartan concentrations in Chinese patients with essential hypertension. AB - This study was conducted to explore interactions in the association of the kininogen (KNG1) Ile197Met polymorphism and gender with plasma concentrations of irbesartan in Chinese patients with essential hypertension. A total of 1100 subjects with essential hypertension received a daily oral dose of 150 mg irbesartan for twenty-eight consecutive days. High-performance liquid chromatography-fluorescence (HPLC) was used to detect plasma irbesartan concentrations on day 28. The KNG1 Ile197Met gene polymorphism was determined using high-throughput TaqMan technology. The frequency distribution of KNG1 Ile197Met genotype conformed to the Hardy-Weinberg equilibrium. After 28 days of treatment, patients with the GG genotype had significantly lower irbesartan concentrations (P = 0.033) compared to homozygous TT genotype carriers. After stratifying by gender, male G allele carriers had significantly lower irbesartan concentrations (GG, P = 0.015; TG, P = 0.015, respectively) relative to TT genotype after adjusting for age, region, body mass index (BMI), smoking, and alcohol consumption. However, there was no significant difference in female subjects. A further test for a multiplicative interaction between the KNG1 Ile197Met polymorphism and gender in association with ln-plasma irbesartan concentrations in a multiple linear regression model was also significant (P for interaction = 0.033). This is the first study to suggest that gender may influence the association of the Ile197Met variant of KNG1 with ln-plasma irbesartan concentration. This finding may indicate that the interaction of gender and the KNG1 Ile197Met gene polymorphism can influence plasma trough irbesartan concentrations, which may contribute to a better development of personalized hypertensive treatment in Chinese patients. PMID- 30283091 TI - Afar triple junction triggered by plume-assisted bi-directional continental break up. AB - Divergent ridge-ridge-ridge (R-R-R) triple junctions are one of the most remarkable, yet largely enigmatic, features of plate tectonics. The juncture of the Arabian, Nubian, and Somalian plates is a type-example of the early development stage of a triple junction where three active rifts meet at a 'triple point' in Central Afar. This structure may result from the impingement of the Afar plume into a non-uniformly stressed continental lithosphere, but this process has never been reproduced by self-consistent plume-lithosphere interaction experiments. Here we use 3D thermo-mechanical numerical models to examine the initiation of plume-induced rift systems under variable far-field stress conditions. Whereas simple linear rift structures are preferred under uni directional extension, we find that more complex patterns form in response to bi directional extension, combining one or several R-R-R triple junctions. These triple junctions optimize the geometry of continental break-up by minimizing the amount of dissipative mechanical work required to accommodate multi-directional extension. Our models suggest that Afar-like triple junctions are an end-member mode of plume-induced bi-directional rifting that combines asymmetrical northward pull and symmetrical EW extension at similar rates. PMID- 30283092 TI - Two coupled circadian oscillations regulate Bmal1-ELuc and Per2-SLR2 expression in the mouse suprachiasmatic nucleus. AB - Circadian rhythms in clock genes, Bmal1 and Per2 expression were monitored simultaneously in the cultured slice of mouse suprachiasmatic nucleus (SCN) by dual bioluminescent reporters. In the neonatal SCN, the phase-relation between the Bmal1 and Per2 rhythms were significantly changed during culture. Medium exchange produced phase-dependent phase shifts (PRCm) in the Bmal1 rhythms, but not in the Per2 rhythms. As a result, the two circadian rhythms were temporally dissociated after medium exchange. In the adult SCN, the phase-relation between the two rhythms was kept constant during culture at least up to 20 cycles. The amplitude of PRCm in the adult SCN was significantly attenuated in the Bmal1 rhythm, whereas a PRCm was developed in the Per2 rhythm. The circadian period was not systematically affected by medium exchange in either of rhythms, regardless of whether it was in the neonatal or the adult SCN. Tetrodotoxin, a sodium channel blocker, enhanced the phase-response in both rhythms but abolished the phase-dependency. In addition, tetrodotoxin lengthened the circadian period independent of the phase of administration. Thus, the Bmal1 and Per2 rhythms in the SCN are dissociable and likely regulated by distinct circadian oscillators. Bmal1 is the component of a Bmal1/REV-ERBa/ROR loop and Per2 a Per/Cry/BMAL1/CLOCK loop. Both loops could be molecular mechanisms of the two circadian oscillators that are coupled through the protein product of Bmal1. The coupling strength between the two oscillations depends on developmental stages. PMID- 30283094 TI - Growth hormone excess in neurofibromatosis 1. PMID- 30283093 TI - Evaluation of Hypoglycaemia with Non-Invasive Sensors in People with Type 1 Diabetes and Impaired Awareness of Hypoglycaemia. AB - People with type 1 diabetes and impaired awareness of hypoglycaemia (IAH) are prone to severe hypoglycaemia. Previous attempts to develop non-invasive hypoglycaemia alarm systems have shown promising results, but it is not known if such alarms can detect severe hypoglycaemia in people with IAH. We aimed to explore whether a combination of non-invasive sensors could reliably evaluate hypoglycaemia (plasma glucose (PG) minimum 2.5 mmol/L) in people with IAH. Twenty participants with type 1 diabetes and IAH underwent randomly ordered, single blinded hyperinsulinemic euglycaemic and hyperinsulinemic hypoglycaemic clamps. Sweating, skin temperature, ECG, counterregulatory hormones and symptoms of hypoglycaemia were assessed. Overall, we were not able to detect clamp-induced hypoglycaemia with sufficient sensitivity and specificity for further clinical use. As a post-hoc analysis, we stratified participants according to their ability to identify hypoglycaemic symptoms during hypoglycaemic clamps. Five out of 20 participants could identify such symptoms. These participants had a significantly higher adrenaline response to hypoglycaemia (p < 0.001) and were reliably identified by sensors. Based on our observations, a non-invasive alarm system based on measurement of sweating responses and ECG changes during hypoglycaemia might provide an alert at a plasma glucose concentration around 2.5 mmol/L if an adequate sympatho-adrenal reaction is elicited.

PMID- 30283097 TI - Gut Colonization with Methanogenic Archaea Lowers Plasma Trimethylamine N-oxide Concentrations in Apolipoprotein e-/- Mice. AB - A mechanistic link between trimethylamine N-oxide (TMAO) and atherogenesis has been reported. TMAO is generated enzymatically in the liver by the oxidation of trimethylamine (TMA), which is produced from dietary choline, carnitine and betaine by gut bacteria. It is known that certain members of methanogenic archaea (MA) could use methylated amines such as trimethylamine as growth substrates in culture. Therefore, we investigated the efficacy of gut colonization with MA on lowering plasma TMAO concentrations. Initially, we screened for the colonization potential and TMAO lowering efficacy of five MA species in C57BL/6 mice fed with high choline/TMA supplemented diet, and found out that all five species could colonize and lover plasma TMAO levels, although with different efficacies. The top performing MA, Methanobrevibacter smithii, Methanosarcina mazei, and Methanomicrococcus blatticola, were transplanted into Apoe-/- mice fed with high choline/TMA supplemented diet. Similar to C57BL/6 mice, following initial provision of the MA, there was progressive attrition of MA within fecal microbial communities post-transplantation during the initial 3 weeks of the study. In general, plasma TMAO concentrations decreased significantly in proportion to the level of MA colonization. In a subsequent experiment, use of antibiotics and repeated transplantation of Apoe-/- mice with M. smithii, led to high engraftment levels during the 9 weeks of the study, resulting in a sustained and significantly lower average plasma TMAO concentrations (18.2 +/- 19.6 MUM) compared to that in mock-transplanted control mice (120.8 +/- 13.0 MUM, p < 0.001). Compared to control Apoe-/- mice, M. smithii-colonized mice also had a 44% decrease in aortic plaque area (8,570 MUm [95% CI 19587-151821] vs. 15,369 MUm [95% CI [70058-237321], p = 0.34), and 52% reduction in the fat content in the atherosclerotic plaques (14,283 MUm [95% CI 4,957-23,608] vs. 29,870 MUm [95% CI 18,074-41,666], p = 0.10), although these differences did not reach significance. Gut colonization with M. smithii leads to a significant reduction in plasma TMAO levels, with a tendency for attenuation of atherosclerosis burden in Apoe-/- mice. The anti-atherogenic potential of MA should be further tested in adequately powered experiments. PMID- 30283098 TI - NF-kappaB-related decrease of glioma angiogenic potential by graphite nanoparticles and graphene oxide nanoplatelets. AB - Gliomas develop an expanded vessel network and a microenvironment characterized by an altered redox environment, which produces high levels of reactive oxygen species (ROS) and reactive nitrogen species (RNS) that fuel its growth and malignancy. ROS and RNS can influence tumor cell malignancy via the redox regulated transcription factor NF-kappaB, whose activation is further regulated by the mutation status of p53. The objective of this study was to assess the influence of graphite nanoparticles (NG) and graphene oxide nanoplatelets (nGO) on the angiogenic potential of glioma cell lines with different p53 statuses. Nanoparticle treatment of glioma cells decreased the angiogenesis of human umbilical vein endothelial cells (HUVEC) cocultured with U87 (p53 wild type) and was not effective for U118 (p53 mutant) cells. Nanoparticle activity was related to the decreased level of intracellular ROS and RNS, which downregulated NF kappaB signaling depending on the p53 status of the cell line. Activation of NF kappaB signaling affected downstream protein levels of interleukin 6, interleukin 8, growth-regulated oncogene alpha, and monocyte chemotactic protein 1. These results indicate that the activity of NG and nGO can be regulated by the mutation status of glioma cells and therefore give new insights into the use of nanoparticles in personalized biomedical applications regarding glioma angiogenesis and its microenvironment. PMID- 30283099 TI - Connectivity of larval stages of sedentary marine communities between hard substrates and offshore structures in the North Sea. AB - Man-made structures including rigs, pipelines, cables, renewable energy devices, and ship wrecks, offer hard substrate in the largely soft-sediment environment of the North Sea. These structures become colonised by sedentary organisms and non migratory reef fish, and form local ecosystems that attract larger predators including seals, birds, and fish. It is possible that these structures form a system of interconnected reef environments through the planktonic dispersal of the pelagic stages of organisms by ocean currents. Changes to the overall arrangement of hard substrate areas through removal or addition of individual man made structures will affect the interconnectivity and could impact on the ecosystem. Here, we assessed the connectivity of sectors with oil and gas structures, wind farms, wrecks, and natural hard substrate, using a model that simulates the drift of planktonic stages of seven organisms with sedentary adult stages associated with hard substrate, applied to the period 2001-2010. Connectivity was assessed using a classification system designed to address the function of sectors in the network. Results showed a relatively stable overall spatial distribution of sector function but with distinct variations between species and years. The results are discussed in the context of decommissioning of oil and gas infrastructure in the North Sea. PMID- 30283100 TI - Complex rice systems to improve rice yield and yield stability in the face of variable weather conditions. AB - Extreme weather events and pest outbreaks decrease rice yields and increase their variability, presenting challenges for the agricultural agenda to increase rice productivity and yield stability in Asia. The integration of azolla, fish and ducks has been shown to create robust systems that maintain high yields under heavy rainfall, but no clear evidence exists that rice yields in these systems are stable across locations and throughout time under divergent weather conditions. We show that the introduction of additional elements into the rice cropping system enhanced the adaptive capacity to extreme weather events across four locations and three cropping cycles. The complex system showed both static and dynamic stability, and had the highest reliability index, thereby outperforming the conventional and organic monoculture systems. The complex rice system design provides a promising example for resilience towards the impacts of climate change on rice production and for safeguarding food security in Asia and beyond.

PMID- 30283102 TI - Ferroelectric polymers exhibiting behaviour reminiscent of a morphotropic phase boundary. AB - Piezoelectricity-the direct interconversion between mechanical and electrical energies-is usually remarkably enhanced at the morphotropic phase boundary of ferroelectric materials1-4, which marks a transition region in the phase diagram of piezoelectric materials and bridges two competing phases with distinct symmetries1,5. Such enhancement has enabled the recent development of various lead and lead-free piezoelectric perovskites with outstanding piezoelectric properties for use in actuators, transducers, sensors and energy-harvesting applications5-8. However, the morphotropic phase boundary has never been observed in organic materials, and the absence of effective approaches to improving the intrinsic piezoelectric responses of polymers9,10 considerably hampers their application to flexible, wearable and biocompatible devices. Here we report stereochemically induced behaviour in ferroelectric poly(vinylidene fluoride-co trifluoroethylene) (P(VDF-TrFE)) copolymers, which is similar to that observed at morphotropic phase boundaries in perovskites. We reveal that compositionally tailored tacticity (the stereochemical arrangement of chiral centres related to the TrFE monomers11,12) can lead to intramolecular order-to-disorder evolution in the crystalline phase and thus to an intermediate transition region that is reminiscent of the morphotropic phase boundary, where competing ferroelectric and relaxor properties appear simultaneously. Our first-principles calculations confirm the crucial role of chain tacticity in driving the formation of this transition region via structural competition between the trans-planar and 3/1 helical phases. We show that the P(VDF-TrFE) copolymer with the morphotropic composition exhibits a longitudinal piezoelectric coefficient of -63.5 picocoulombs per newton, outperforming state-of-the-art piezoelectric polymers10. Given the flexibility in the molecular design and synthesis of organic ferroelectric materials, this work opens up the way for the development of scalable, high-performance piezoelectric polymers. PMID- 30283103 TI - Asymmetric alpha-arylation of amino acids. AB - Quaternary amino acids, in which the alpha-carbon that bears the amino and carboxyl groups also carries two carbon substituents, have an important role as modifiers of peptide conformation and bioactivity and as precursors of medicinally important compounds1,2. In contrast to enantioselective alkylation at this alpha-carbon, for which there are several methods3-8, general enantioselective introduction of an aryl substituent at the alpha-carbon is synthetically challenging9. Nonetheless, the resultant alpha-aryl amino acids and their derivatives are valuable precursors to bioactive molecules10,11. Here we describe the synthesis of quaternary alpha-aryl amino acids from enantiopure amino acid precursors by alpha-arylation without loss of stereochemical integrity. Our approach relies on the temporary formation of a second stereogenic centre in an N'-arylurea adduct12 of an imidazolidinone derivative6 of the precursor amino acid, and uses readily available enantiopure amino acids both as a precursor and as a source of asymmetry. It avoids the use of valuable transition metals, and enables arylation with electron-rich, electron-poor and heterocyclic substituents. Either enantiomer of the product can be formed from a single amino acid precursor. The method is practical and scalable, and provides the opportunity to produce alpha-arylated quaternary amino acids in multi-gram quantities. PMID- 30283104 TI - A new era in the search for dark matter. AB - There is a growing sense of 'crisis' in the dark-matter particle community, which arises from the absence of evidence for the most popular candidates for dark matter particles-such as weakly interacting massive particles, axions and sterile neutrinos-despite the enormous effort that has gone into searching for these particles. Here we discuss what we have learned about the nature of dark matter from past experiments and the implications for planned dark-matter searches in the next decade. We argue that diversifying the experimental effort and incorporating astronomical surveys and gravitational-wave observations is our best hope of making progress on the dark-matter problem. PMID- 30283105 TI - Widespread seasonal compensation effects of spring warming on northern plant productivity. AB - Climate change is shifting the phenological cycles of plants1, thereby altering the functioning of ecosystems, which in turn induces feedbacks to the climate system2. In northern (north of 30 degrees N) ecosystems, warmer springs lead generally to an earlier onset of the growing season3,4 and increased ecosystem productivity early in the season5. In situ6 and regional7-9 studies also provide evidence for lagged effects of spring warmth on plant productivity during the subsequent summer and autumn. However, our current understanding of these lagged effects, including their direction (beneficial or adverse) and geographic distribution, is still very limited. Here we analyse satellite, field-based and modelled data for the period 1982-2011 and show that there are widespread and contrasting lagged productivity responses to spring warmth across northern ecosystems. On the basis of the observational data, we find that roughly 15 per cent of the total study area of about 41 million square kilometres exhibits adverse lagged effects and that roughly 5 per cent of the total study area exhibits beneficial lagged effects. By contrast, current-generation terrestrial carbon-cycle models predict much lower areal fractions of adverse lagged effects (ranging from 1 to 14 per cent) and much higher areal fractions of beneficial lagged effects (ranging from 9 to 54 per cent). We find that elevation and seasonal precipitation patterns largely dictate the geographic pattern and direction of the lagged effects. Inadequate consideration in current models of the effects of the seasonal build-up of water stress on seasonal vegetation growth may therefore be able to explain the differences that we found between our observation-constrained estimates and the model-constrained estimates of lagged effects associated with spring warming. Overall, our results suggest that for many northern ecosystems the benefits of warmer springs on growing-season ecosystem productivity are effectively compensated for by the accumulation of seasonal water deficits, despite the fact that northern ecosystems are thought to be largely temperature- and radiation-limited10.

AB - SS 433 is a binary system containing a supergiant star that is overflowing its Roche lobe with matter accreting onto a compact object (either a black hole or neutron star)1-3. Two jets of ionized matter with a bulk velocity of approximately 0.26c (where c is the speed of light in vacuum) extend from the binary, perpendicular to the line of sight, and terminate inside W50, a supernova remnant that is being distorted by the jets2,4-8. SS 433 differs from other microquasars (small-scale versions of quasars that are present within our own Galaxy) in that the accretion is believed to be super-Eddington9-11, and the luminosity of the system is about 1040 ergs per second2,9,12,13. The lobes of W50 in which the jets terminate, about 40 parsecs from the central source, are expected to accelerate charged particles, and indeed radio and X-ray emission consistent with electron synchrotron emission in a magnetic field have been observed14-16. At higher energies (greater than 100 gigaelectronvolts), the particle fluxes of gamma-rays from X-ray hotspots around SS 433 have been reported as flux upper limits6,17-20. In this energy regime, it has been unclear whether the emission is dominated by electrons that are interacting with photons from the cosmic microwave background through inverse-Compton scattering or by protons that are interacting with the ambient gas. Here we report teraelectronvolt gamma-ray observations of the SS 433/W50 system that spatially resolve the lobes. The teraelectronvolt emission is localized to structures in the lobes, far from the centre of the system where the jets are formed. We have measured photon energies of at least 25 teraelectronvolts, and these are certainly not Doppler-boosted, because of the viewing geometry. We conclude that the emission-from radio to teraelectronvolt energies-is consistent with a single population of electrons with energies extending to at least hundreds of teraelectronvolts in a magnetic field of about 16 microgauss.

PMID- 30283129 TI - Thermal efficiency of a thermocell made of Prussian blue analogues. AB - Recently, it was reported that a thermocell can convert temperature into electric energy by using the difference in the thermal coefficient (alpha = dV/dT) of the redox potential (V) between the cathode and anode materials. Among battery materials, Prussian blue analogues (PBAs) are promising materials for thermocell, because alpha changes from approximately -0.3 mV/K in NaxMn[Fe(CN)6]0.83 3.5 H2O (NMF83) to approximately 1.3 mV/K in NaxCo[Fe(CN)6]0.92,9H2O (NCF90). In this work, we systematically investigated the thermal efficiency (eta) of the NMF83/NCF90 thermocell relative to the difference (DeltaT) between low (TL = 282 K) and high (TH = 292-338 K) temperatures. We found that the thermal efficiency (eta) increased proportionally with DeltaT. The linear increase in eta is ascribed to the linear increase in the cell voltage (Vcell) and the charge (QNCF90) extracted from NCF90. Moreover, eta reached 3.19% at DeltaT = 56 K, which corresponds to 19% of the Carnot efficiency (etacarnot = 17.0%). We further confirmed that the magnitude of QNCF90 is quantitatively reproduced by the slopes of the discharge curves of NMF83 and NCF90. PMID- 30283130 TI - Caloric restriction promotes functional changes involving short-chain fatty acid biosynthesis in the rat gut microbiota. AB - Caloric restriction (CR) is known to promote health and longevity, likely via modification of the gut microbiota (GM). However, functional and metabolic changes induced in the GM during CR are still unidentified. Here, we investigated the short- and long-term effects of CR on the rat GM using a metaproteogenomic approach. We show that a switch from ad libitum (AL) low fat diet to CR in young rats is able to induce rapid and deep changes in their GM metaproteomic profile, related to a reduction of the Firmicutes/Bacteroidetes ratio and an expansion of lactobacilli. Specifically, we observed a significant change in the expression of the microbial enzymes responsible for short-chain fatty acid biosynthesis, with CR boosting propionogenesis and limiting butyrogenesis and acetogenesis. Furthermore, these CR-induced effects were maintained up to adulthood and started to be reversed after a short-term diet change. We also found that CR alters the abundance of an array of host proteins released in stool, mainly related to epithelial barrier integrity and inflammation. Hence, our results provide thorough information about CR-induced modifications to GM and host functional activity, and might constitute the basis for novel GM-based approaches aimed at monitoring the effectiveness of dietary interventions. PMID- 30283132 TI - Genomes of Asgard archaea encode profilins that regulate actin. AB - The origin of the eukaryotic cell is unresolved1,2. Metagenomics sequencing has recently identified several potential eukaryotic gene homologues in Asgard archaea3,4, consistent with the hypothesis that the eukaryotic cell evolved from within the Archaea domain. However, many of these eukaryotic-like sequences are highly divergent and the organisms have yet to be imaged or cultivated, which brings into question the extent to which these archaeal proteins represent functional equivalents of their eukaryotic counterparts. Here we show that Asgard archaea encode functional profilins and thereby establish that this archaeal superphylum has a regulated actin cytoskeleton, one of the hallmarks of the eukaryotic cell5. Loki profilin-1, Loki profilin-2 and Odin profilin adopt the typical profilin fold and are able to interact with rabbit actin-an interaction that involves proteins from species that diverged more than 1.2 billion years ago6. Biochemical experiments reveal that mammalian actin polymerizes in the presence of Asgard profilins; however, Loki, Odin and Heimdall profilins impede pointed-end elongation. These archaeal profilins also retard the spontaneous nucleation of actin filaments, an effect that is reduced in the presence of phospholipids. Asgard profilins do not interact with polyproline motifs and the profilin-polyproline interaction therefore probably evolved later in the Eukarya lineage. These results suggest that Asgard archaea possess a primordial, polar, profilin-regulated actin system, which may be localized to membranes owing to the sensitivity of Asgard profilins to phospholipids. Because Asgard archaea are also predicted to encode potential eukaryotic-like genes involved in membrane trafficking and endocytosis3,4, imaging is now necessary to elucidate whether these organisms are capable of generating eukaryotic-like membrane dynamics that are regulated by actin, such as are observed in eukaryotic cell movement, podosomes and endocytosis. PMID- 30283133 TI - Crystal structure of a membrane-bound O-acyltransferase. AB - Membrane-bound O-acyltransferases (MBOATs) are a superfamily of integral transmembrane enzymes that are found in all kingdoms of life1. In bacteria, MBOATs modify protective cell-surface polymers. In vertebrates, some MBOAT enzymes-such as acyl-coenzyme A:cholesterol acyltransferase and diacylglycerol acyltransferase 1-are responsible for lipid biosynthesis or phospholipid remodelling2,3. Other MBOATs, including porcupine, hedgehog acyltransferase and ghrelin acyltransferase, catalyse essential lipid modifications of secreted proteins such as Wnt, hedgehog and ghrelin, respectively4-10. Although many MBOAT proteins are important drug targets, little is known about their molecular architecture and functional mechanisms. Here we present crystal structures of DltB, an MBOAT responsible for the D-alanylation of cell-wall teichoic acid in Gram-positive bacteria11-16, both alone and in complex with the D-alanyl donor protein DltC. DltB contains a ring of 11 peripheral transmembrane helices, which shield a highly conserved extracellular structural funnel extending into the middle of the lipid bilayer. The conserved catalytic histidine residue is located at the bottom of this funnel and is connected to the intracellular DltC through a narrow tunnel. Mutation of either the catalytic histidine or the DltC-binding site of DltB abolishes the D-alanylation of lipoteichoic acid and sensitizes the Gram-positive bacterium Bacillus subtilis to cell-wall stress, which suggests cross-membrane catalysis involving the tunnel. Structure-guided sequence comparison among DltB and vertebrate MBOATs reveals a conserved structural core and suggests that MBOATs from different organisms have similar catalytic mechanisms. Our structures provide a template for understanding structure function relationships in MBOATs and for developing therapeutic MBOAT inhibitors. PMID- 30283135 TI - Transcriptional recording by CRISPR spacer acquisition from RNA. AB - The ability to record transcriptional events within a cell over time would help to elucidate how molecular events give rise to complex cellular behaviours and states. However, current molecular recording technologies capture only a small set of defined stimuli. Here we use CRISPR spacer acquisition to capture and convert intracellular RNAs into DNA, enabling DNA-based storage of transcriptional information. In Escherichia coli, we show that defined stimuli, such as an RNA virus or arbitrary sequences, as well as complex stimuli, such as oxidative stress, result in quantifiable transcriptional records that are stored within a population of cells. We demonstrate that the transcriptional records enable us to classify and describe complex cellular behaviours and to identify the precise genes that orchestrate differential cellular responses. In the future, CRISPR spacer acquisition-mediated recording of RNA followed by deep sequencing (Record-seq) could be used to reconstruct transcriptional histories that describe complex cell behaviours or pathological states. PMID- 30283134 TI - Multi-axial self-organization properties of mouse embryonic stem cells into gastruloids. AB - The emergence of multiple axes is an essential element in the establishment of the mammalian body plan. This process takes place shortly after implantation of the embryo within the uterus and relies on the activity of gene regulatory networks that coordinate transcription in space and time. Whereas genetic approaches have revealed important aspects of these processes1, a mechanistic understanding is hampered by the poor experimental accessibility of early post implantation stages. Here we show that small aggregates of mouse embryonic stem cells (ESCs), when stimulated to undergo gastrulation-like events and elongation in vitro, can organize a post-occipital pattern of neural, mesodermal and endodermal derivatives that mimic embryonic spatial and temporal gene expression. The establishment of the three major body axes in these 'gastruloids'2,3 suggests that the mechanisms involved are interdependent. Specifically, gastruloids display the hallmarks of axial gene regulatory systems as exemplified by the implementation of collinear Hox transcriptional patterns along an extending antero-posterior axis. These results reveal an unanticipated self-organizing capacity of aggregated ESCs and suggest that gastruloids could be used as a complementary system to study early developmental events in the mammalian embryo. PMID- 30283136 TI - OTX2 restricts entry to the mouse germline. AB - The successful segregation of germ cells from somatic lineages is vital for sexual reproduction and species survival. In the mouse, primordial germ cells (PGCs), precursors of all germ cells, are induced from the post-implantation epiblast1. Induction requires BMP4 signalling to prospective PGCs2 and the intrinsic action of PGC transcription factors3-6. However, the molecular mechanisms that connect BMP4 to induction of the PGC transcription factors that are responsible for segregating PGCs from somatic lineages are unknown. Here we show that the transcription factor OTX2 is a key regulator of these processes. Downregulation of Otx2 precedes the initiation of the PGC programme both in vitro and in vivo. Deletion of Otx2 in vitro markedly increases the efficiency of PGC like cell differentiation and prolongs the period of PGC competence. In the absence of Otx2 activity, differentiation of PGC-like cells becomes independent of the otherwise essential cytokine signals, with germline entry initiating even in the absence of the PGC transcription factor BLIMP1. Deletion of Otx2 in vivo increases PGC numbers. These data demonstrate that OTX2 functions repressively upstream of PGC transcription factors, acting as a roadblock to limit entry of epiblast cells to the germline to a small window in space and time, thereby ensuring correct numerical segregation of germline cells from the soma.

AB - Mitochondrial protein synthesis requires charging mt-tRNAs with their cognate amino acids by mitochondrial aminoacyl-tRNA synthetases, with the exception of glutaminyl mt-tRNA (mt-tRNAGln). mt-tRNAGln is indirectly charged by a transamidation reaction involving the GatCAB aminoacyl-tRNA amidotransferase complex. Defects involving the mitochondrial protein synthesis machinery cause a broad spectrum of disorders, with often fatal outcome. Here, we describe nine patients from five families with genetic defects in a GatCAB complex subunit, including QRSL1, GATB, and GATC, each showing a lethal metabolic cardiomyopathy syndrome. Functional studies reveal combined respiratory chain enzyme deficiencies and mitochondrial dysfunction. Aminoacylation of mt-tRNAGln and mitochondrial protein translation are deficient in patients' fibroblasts cultured in the absence of glutamine but restore in high glutamine. Lentiviral rescue experiments and modeling in S. cerevisiae homologs confirm pathogenicity. Our study completes a decade of investigations on mitochondrial aminoacylation disorders, starting with DARS2 and ending with the GatCAB complex.

AB - Climate warming will influence photosynthesis via thermal effects and by altering soil moisture1-11. Both effects may be important for the vast areas of global forests that fluctuate between periods when cool temperatures limit photosynthesis and periods when soil moisture may be limiting to carbon gain4-6,9 11. Here we show that the effects of climate warming flip from positive to negative as southern boreal forests transition from rainy to modestly dry periods during the growing season. In a three-year open-air warming experiment with juveniles of 11 temperate and boreal tree species, an increase of 3.4 degrees C in temperature increased light-saturated net photosynthesis and leaf diffusive conductance on average on the one-third of days with the wettest soils. In all 11 species, leaf diffusive conductance and, as a result, light-saturated net photosynthesis decreased during dry spells, and did so more sharply in warmed plants than in plants at ambient temperatures. Consequently, across the 11 species, warming reduced light-saturated net photosynthesis on the two-thirds of days with driest soils. Thus, low soil moisture may reduce, or even reverse, the potential benefits of climate warming on photosynthesis in mesic, seasonally cold environments, both during drought and in regularly occurring, modestly dry periods during the growing season. PMID- 30283138 TI - Antibody and TLR7 agonist delay viral rebound in SHIV-infected monkeys. AB - The latent viral reservoir is the critical barrier for the development of a cure for HIV-1 infection. Previous studies have shown direct antiviral activity of potent HIV-1 Env-specific broadly neutralizing antibodies (bNAbs) administered when antiretroviral therapy (ART) was discontinued, but it remains unclear whether bNAbs can target the viral reservoir during ART. Here we show that administration of the V3 glycan-dependent bNAb PGT121 together with the Toll-like receptor 7 (TLR7) agonist vesatolimod (GS-9620) during ART delayed viral rebound following discontinuation of ART in simian-human immunodeficiency virus (SHIV) SF162P3-infected rhesus monkeys in which ART was initiated during early acute infection. Moreover, in the subset of monkeys that were treated with both PGT121 and GS-9620 and that did not show viral rebound after discontinuation of ART, adoptive transfer studies and CD8-depletion studies also did not reveal virus. These data demonstrate the potential of bNAb administration together with innate immune stimulation as a possible strategy for targeting the viral reservoir. PMID- 30283139 TI - Solution-processable 2D semiconductors for high-performance large-area electronics. AB - Two-dimensional (2D) materials, consisting of atomically thin crystal layers bound by the van der Waals force, have attracted much interest because of their potential in diverse technologies, including electronics, optoelectronics and catalysis1-10. In particular, solution-processable 2D semiconductor (such as MoS2) nanosheets are attractive building blocks for large-area thin-film electronics. In contrast to conventional zero- and one-dimensional nanostructures (quantum dots and nanowires, respectively), which are typically plagued by surface dangling bonds and associated trapping states, 2D nanosheets have dangling-bond-free surfaces. Thin films created by stacking multiple nanosheets have atomically clean van der Waals interfaces and thus promise excellent charge transport11-15. However, preparing high-quality solution-processable 2D semiconductor nanosheets remains a challenge. For example, MoS2 nanosheets and thin films produced using lithium intercalation and exfoliation are plagued by the presence of the metallic 1T phase and poor electrical performance (mobilities of about 0.3 square centimetres per volt per second and on/off ratios of less than 10)2,12, and materials produced by liquid exfoliation exhibit an intrinsically broad thickness distribution, which leads to poor film quality and unsatisfactory thin-film electrical performance (mobilities of about 0.4 square centimetres per volt per second and on/off ratios of about 100)14,16,17. Here we report a general approach to preparing highly uniform, solution-processable, phase-pure semiconducting nanosheets, which involves the electrochemical intercalation of quaternary ammonium molecules (such as tetraheptylammonium bromide) into 2D crystals, followed by a mild sonication and exfoliation process. By precisely controlling the intercalation chemistry, we obtained phase-pure, semiconducting 2H-MoS2 nanosheets with a narrow thickness distribution. These nanosheets were then further processed into high-performance thin-film transistors, with room-temperature mobilities of about 10 square centimetres per volt per second and on/off ratios of 106 that greatly exceed those obtained for previous solution-processed MoS2 thin-film transistors. The scalable fabrication of large-area arrays of thin-film transistors enabled the construction of functional logic gates and computational circuits, including an inverter, NAND, NOR, AND and XOR gates, and a logic half-adder. We also applied our approach to other 2D materials, including WSe2, Bi2Se3, NbSe2, In2Se3, Sb2Te3 and black phosphorus, demonstrating its potential for generating versatile solution processable 2D materials. PMID- 30283140 TI - Handover mechanism of the growing pilus by the bacterial outer-membrane usher FimD. AB - Pathogenic bacteria such as Escherichia coli assemble surface structures termed pili, or fimbriae, to mediate binding to host-cell receptors1. Type 1 pili are assembled via the conserved chaperone-usher pathway2-5. The outer-membrane usher FimD recruits pilus subunits bound by the chaperone FimC via the periplasmic N terminal domain of the usher. Subunit translocation through the beta-barrel channel of the usher occurs at the two C-terminal domains (which we label CTD1 and CTD2) of this protein. How the chaperone-subunit complex bound to the N terminal domain is handed over to the C-terminal domains, as well as the timing of subunit polymerization into the growing pilus, have previously been unclear. Here we use cryo-electron microscopy to capture a pilus assembly intermediate (FimD-FimC-FimF-FimG-FimH) in a conformation in which FimD is in the process of handing over the chaperone-bound end of the growing pilus to the C-terminal domains. In this structure, FimF has already polymerized with FimG, and the N terminal domain of FimD swings over to bind CTD2; the N-terminal domain maintains contact with FimC-FimF, while at the same time permitting access to the C terminal domains. FimD has an intrinsically disordered N-terminal tail that precedes the N-terminal domain. This N-terminal tail folds into a helical motif upon recruiting the FimC-subunit complex, but reorganizes into a loop to bind CTD2 during handover. Because both the N-terminal and C-terminal domains of FimD are bound to the end of the growing pilus, the structure further suggests a mechanism for stabilizing the assembly intermediate to prevent the pilus fibre diffusing away during the incorporation of thousands of subunits.

AB - BACKGROUND: Constitutional MLH1 epimutations are characterised by monoallelic methylation of the MLH1 promoter throughout normal tissues, accompanied by allele specific silencing. The mechanism underlying primary MLH1 epimutations is currently unknown. The aim of this study was to perform an in-depth characterisation of constitutional MLH1 epimutations targeting the aberrantly methylated region around MLH1 and other genomic loci. METHODS: Twelve MLH1 epimutation carriers, 61 Lynch syndrome patients, and 41 healthy controls, were analysed by Infinium 450 K array. Targeted molecular techniques were used to characterise the MLH1 epimutation carriers and their inheritance pattern. RESULTS: No nucleotide or structural variants were identified in-cis on the epimutated allele in 10 carriers, in which inter-generational methylation erasure was demonstrated in two, suggesting primary type of epimutation. CNVs outside the MLH1 locus were found in two cases. EPM2AIP1-MLH1 CpG island was identified as the sole differentially methylated region in MLH1 epimutation carriers compared to controls. CONCLUSION: Primary constitutional MLH1 epimutations arise as a focal epigenetic event at the EPM2AIP1-MLH1 CpG island in the absence of cis acting genetic variants. Further molecular characterisation is needed to elucidate the mechanistic basis of MLH1 epimutations and their heritability/reversibility.

PMID- 30283144 TI - Colon-specific eQTL analysis to inform on functional SNPs. AB - BACKGROUND: Genome-wide association studies on colorectal cancer have identified more than 60 susceptibility loci, but for most of them there is no clear knowledge of functionality or the underlying gene responsible for the risk modification. Expression quantitative trail loci (eQTL) may provide functional information for such single nucleotide polymorphisms (SNPs). METHODS: We have performed detailed eQTL analysis specific for colon tissue on a series of 97 colon tumours, their paired adjacent normal mucosa and 47 colon mucosa samples donated by healthy individuals. R package MatrixEQTL was used to search for genome-wide cis-eQTL and trans-eQTL fitting linear models adjusted for age, gender and tissue type to rank transformed expression data. RESULTS: The cis-eQTL analyses has revealed 29,073 SNP-gene associations with permutation-adjusted P values < 0.01. These correspond to 363 unique genes. The trans-eQTL analysis identified 10,665 significant SNP-gene associations, most of them in the same chromosome, further than 1 Mb of the gene. We provide a web tool to search for specific SNPs or genes. The tool calculates Pearson or Spearman correlation, and allows to select tissue type for analysis. Data and plots can be exported. CONCLUSIONS: This resource should be useful to prioritise SNPs for further functional studies and to identify relevant genes behind identified loci. PMID- 30283146 TI - Parallel phylogeography of Prochlorococcus and Synechococcus. AB - The globally abundant marine Cyanobacteria Prochlorococcus and Synechococcus share many physiological traits but presumably have different evolutionary histories and associated phylogeography. In Prochlorococcus, there is a clear phylogenetic hierarchy of ecotypes, whereas multiple Synechococcus clades have overlapping physiologies and environmental distributions. However, microbial traits are associated with different phylogenetic depths. Using this principle, we reclassified diversity at different phylogenetic levels and compared the phylogeography. We sequenced the genetic diversity of Prochlorococcus and Synechococcus from 339 samples across the tropical Pacific Ocean and North Atlantic Ocean using a highly variable phylogenetic marker gene (rpoC1). We observed clear parallel niche distributions of ecotypes leading to high Pianka's Index values driven by distinct shifts at two transition points. The first transition point at 6 degrees N distinguished ecotypes adapted to warm waters but separated by macronutrient content. At 39 degrees N, ecotypes adapted to warm, low macronutrient vs. colder, high macronutrient waters shifted. Finally, we detected parallel vertical and regional single-nucleotide polymorphism microdiversity within clades from both Prochlorococcus and Synechococcus, suggesting uniquely adapted populations at very specific depths, as well as between the Atlantic and Pacific Oceans. Overall, this study demonstrates that Prochlorococcus and Synechococcus have shared phylogenetic organization of traits and associated phylogeography.

PMID- 30283148 TI - Current use of biosimilar G-CSF for haematopoietic stem cell mobilisation. AB - Despite biosimilars of the granulocyte-colony stimulating factor (G-CSF) filgrastim being approved by the European Medicines Agency since 2008, there is still some debate regarding their use in related and unrelated healthy haematopoietic stem cell donors. We present a review of published experiences using biosimilar filgrastim for healthy donor mobilisation as well as the results of a survey by the World Marrow Donor Association (WMDA) of its current use by register-associated transplant and collection centres for both related and unrelated donors. A total of 1287 healthy donors and volunteers are included in the reviewed studies. The pharmacokinetics and pharmacodynamics studies show a high degree of similarity to the reference product Neupogen. Mobilisation of CD34 + cells as well as reported adverse events are also found to be comparable, although there is still a lack of long-term follow up for both Neupogen and filgrastim biosimilars. No evidence is found of a higher risk of filgrastim antibody formation using filgrastim biosimilars. Based on this increased experience, the WMDA therefore recommend that Stem Cell Donor Registries can use filgrastim biosimilars for the mobilisation of peripheral blood progenitor cells in healthy donors, provided that they are approved by national and/or regional agencies. PMID- 30283141 TI - Single-cell transcriptomics of 20 mouse organs creates a Tabula Muris. AB - Here we present a compendium of single-cell transcriptomic data from the model organism Mus musculus that comprises more than 100,000 cells from 20 organs and tissues. These data represent a new resource for cell biology, reveal gene expression in poorly characterized cell populations and enable the direct and controlled comparison of gene expression in cell types that are shared between tissues, such as T lymphocytes and endothelial cells from different anatomical locations. Two distinct technical approaches were used for most organs: one approach, microfluidic droplet-based 3'-end counting, enabled the survey of thousands of cells at relatively low coverage, whereas the other, full-length transcript analysis based on fluorescence-activated cell sorting, enabled the characterization of cell types with high sensitivity and coverage. The cumulative data provide the foundation for an atlas of transcriptomic cell biology. PMID- 30283149 TI - Multivalent and multifunctional polysaccharide-based particles for controlled receptor recognition. AB - Polysaccharides represent a versatile class of building blocks that are used in macromolecular design. By choosing the appropriate saccharide block, various physico-chemical and biological properties can be introduced both at the level of the polymer chains and the resulting self-assembled nanostructures. Here, we synthetized amphiphilic diblock copolymers combining a hydrophobic and helical poly(gamma-benzyl-L-glutamate) PBLG and two polysaccharides, namely hyaluronic acid (HA) and laminarin (LAM). The copolymers could self-assemble to form particles in water by nanoprecipitation. In addition, hybrid particles containing both HA and LAM in different ratios were obtained by co-nanoprecipitation of the two copolymers. By controlling the self-assembly process, five particle samples with different morphologies and compositions were developed. The interaction between the particles and biologically relevant proteins for HA and LAM, namely CD44 and Dectin-1 respectively, was evaluated by surface plasmon resonance (SPR). We demonstrated that the particle-protein interaction could be modulated by the particle structure and composition. It is therefore suggested that this method based on nanoprecipitation is a practical and versatile way to obtain particles with controllable interactions with proteins, hence with the appropriate biological properties for biomedical applications such as drug delivery. PMID- 30283150 TI - A novel design to screen chlorogenic acid-producing microbial strains from the environment. AB - The present study aimed to develop a plate-screening method, based on the specific color development of complexes formed between chlorogenic acid, a valuable plant-derived compound, and aluminum (III), to detect chlorogenic acid producing microbial strains. Modified media with 0.75 mM aluminum chloride were developed to identify CGA-producing bacteria (based on beef extract agar medium) or fungi (based on the potato dextrose agar medium). Compared with conventional screening, the modified media let to 3.3 times more CGA producers from plants, at 90.9% selective accuracy. Novel chlorogenic acid-biosynthesizing strains included Brevibacillus borstelensis B14, Bacillus amyloliquefaciens B17, Bacillus badius B19, Sphingomonas yabuuchiae N21, Enterobacter tabaci N22, and Lodderomyces elongisporus S216 and P212. Strain S216 produced the highest chlorogenic acid yield (23.39 mg L-1). This study provides a highly efficient and low-cost tool for quick detection and subsequent identification of several newly isolated strains with chlorogenic acid-producing potential. PMID- 30283152 TI - Modeling the two- and three-dimensional displacement field in Lorca, Spain, subsidence and the global implications. AB - Land subsidence associated with overexploitation of aquifers is a hazard that commonly affects large areas worldwide. The Lorca area, located in southeast Spain, has undergone one of the highest subsidence rates in Europe as a direct consequence of long-term aquifer exploitation. Previous studies carried out on the region assumed that the ground deformation retrieved from satellite radar interferometry corresponds only to vertical displacement. Here we report, for the first time, the two- and three-dimensional displacement field over the study area using synthetic aperture radar (SAR) data from Sentinel-1A images and Global Navigation Satellite System (GNSS) observations. By modeling this displacement, we provide new insights on the spatial and temporal evolution of the subsidence processes and on the main governing mechanisms. Additionally, we also demonstrate the importance of knowing both the vertical and horizontal components of the displacement to properly characterize similar hazards. Based on these results, we propose some general guidelines for the sustainable management and monitoring of land subsidence related to anthropogenic activities. PMID- 30283153 TI - The translation of age-related body composition findings from rodents to humans. AB - The objective of this review is to highlight changes in body composition in rodent models as a result of healthy aging in order to enhance translational research. Aging is associated with alterations in body composition, particularly fat mass and fat-free mass, which may be accompanied by adverse health effects, especially nearing middle age to old age. In humans, it is generally understood that fat mass tends to increase while fat-free mass concurrently declines with aging. However, the effect of aging on body composition in rodent models is less well studied, and how these changes compare and contrast with observations in humans has not yet been fully elucidated. Though, it appears as though the constituent-level alterations occur in humans and rodents at different life phases thereby having a potential effect on the outcomes of basic biomedical research. Though highly strain-dependent, this review suggests that FM changes begin at a much earlier life phase in rodents than in humans. Conversely, FFM appears to increase throughout middle age and into old age in rodents, whereas middle age is associated with the initiation the subsequent decline of FFM in humans. Given the essentiality of rodent models in basic biomedical research, careful consideration of these differences in age-related BC findings is imperative when the research is aimed for human translation. PMID- 30283151 TI - Photosystem-II D1 protein mutants of Chlamydomonas reinhardtii in relation to metabolic rewiring and remodelling of H-bond network at QB site. AB - Photosystem II (PSII) reaction centre D1 protein of oxygenic phototrophs is pivotal for sustaining photosynthesis. Also, it is targeted by herbicides and herbicide-resistant weeds harbour single amino acid substitutions in D1. Conservation of D1 primary structure is seminal in the photosynthetic performance in many diverse species. In this study, we analysed built-in and environmentally induced (high temperature and high photon fluency - HT/HL) phenotypes of two D1 mutants of Chlamydomonas reinhardtii with Ala250Arg (A250R) and Ser264Lys (S264K) substitutions. Both mutations differentially affected efficiency of electron transport and oxygen production. In addition, targeted metabolomics revealed that the mutants undergo specific differences in primary and secondary metabolism, namely, amino acids, organic acids, pigments, NAD, xanthophylls and carotenes. Levels of lutein, beta-carotene and zeaxanthin were in sync with their corresponding gene transcripts in response to HT/HL stress treatment in the parental (IL) and A250R strains. D1 structure analysis indicated that, among other effects, remodelling of H-bond network at the QB site might underpin the observed phenotypes. Thus, the D1 protein, in addition to being pivotal for efficient photosynthesis, may have a moonlighting role in rewiring of specific metabolic pathways, possibly involving retrograde signalling. PMID- 30283154 TI - Clara cells protein, prolactin and transcription factors of protein NF-KB and c Jun/AP-1 levels in rats inhaled to stainless steel welding dust and its soluble form. AB - OBJECTIVES: Welding processes that generate fumes containing toxic metals, such as hexavalent chromium (Cr(VI)), manganese, and nickel (Ni), have been implicated in lung injury, inflammation, and lung tumor promotion in animal models. Bronchiolar epithelium Clara cells/club cells, coordinate these inflammatory responses. Clara cells secretory protein (CC16) with ant-inflammatory role. MATERIAL AND METHODS: The pulmonary toxicity of welding dust (WD) was assessed for Wistar rats exposed to 60 mg/m3 of respirable-size welding dust (mean diameter 1.17 MUm for 1 and 2 weeks (6 h/day, 5 days/week)) or the aerosols of soluble form (SWD) in the nose-only exposure chambers. Additionally the effect of antiinflammatory betaine supplementation was assessed. Clara cells secretory protein, differential cell counts, total protein concentrations and cellular enzyme (lactate dehydrogenase - LDH) activities were determined in bronchoalveolar lavage fluid, and corticosterone and thiobarbituric acid reactive substances (TBARS) and prolactin concentrations were assessed in serum. Histopathology examination of lung, brain, liver, kidney, spleen was done. Additionally slices of brain and lung were exanimated in laser ablation inductively coupled plasma mass spectrometry. RESULTS: Both WD and SWD exposure evoked large bronchiolar infiltration shoved in histopathology examination. In this study, TBARS inversely correlated with a significant decrease of CC16 concentration that occurred after instillation of both WD and SWD indicating decreased anti- inflammatory potential in the lung. In WD exposed rats prolactin correlated with nuclear factor-kappa B (NF-kappaB), LDH, TBARS and serum levels Cr, Ni and inversely with c-Jun. In SWD exposed rats prolactin correlated with CC16 indicated effect of prolactin on the population of epithelial cells. CONCLUSIONS: In the current study, deleterious effects of repeated inhalation stainless steel welding dust form on club (Clara) cell secretory protein (CC16) were demonstrated. Clara cells secretory protein relation with prolactin in exposed rats to welding dust were shown and explored whether the NF-kappaB and c Jun/activator protein 1 related pathway was involved.

AB - An approach is described to apply spatial filtering with microphone arrays to localize acoustic sources in an Intensive Care Unit (ICU). This is done to obtain more detailed information about disturbing noise sources in the ICU with the ultimate goal of facilitating the reduction of the overall background noise level, which could potentially improve the patients' experience and reduce the time needed for recovery. This paper gives a practical description of the system, including the audio hardware setup as well as the design choices for the microphone arrays. Additionally, the necessary signal processing steps required to produce meaningful data are explained, focusing on a novel clustering approach that enables an automatic evaluation of the spatial filtering results. This approach allows the data to be presented to the nursing staff in a way that enables them to act on the results produced by the system.

AB - This paper examines the possibilities of creating quantified models of past human activities in both time and space. The study area lies in the southeastern Czech Republic and western Slovakia. The spatio-temporal model of behavioural categories was calculated with the help of Monte Carlo simulations and statistical testing. One of the main advantages of our approach is that it admits the probabilistic nature of input data, quantifies them and provides probabilistic results comparable with other proxies. It also presents a less biased way of how archaeological data from regions and periods with low numbers of 14C datings can be incorporated into models of past population dynamics. PMID- 30283157 TI - Feature selection by optimizing a lower bound of conditional mutual information. AB - A unified framework is proposed to select features by optimizing computationally feasible approximations of high-dimensional conditional mutual information (CMI) between features and their associated class label under different assumptions. Under this unified framework, state-of-the-art information theory based feature selection algorithms are rederived, and a new algorithm is proposed to select features by optimizing a lower bound of the CMI with a weaker assumption than those adopted by existing methods. The new feature selection method integrates a plug-in component to distinguish redundant features from irrelevant ones for improving the feature selection robustness. Furthermore, a novel metric is proposed to evaluate feature selection methods based on simulated data. The proposed method has been compared with state-of-the-art feature selection methods based on the new evaluation metric and classification performance of classifiers built upon the selected features. The experiment results have demonstrated that the proposed method could achieve promising performance in a variety of feature selection problems. PMID- 30283158 TI - Odd-even effect on the formation of aqueous biphasic systems formed by 1-alkyl-3 methylimidazolium chloride ionic liquids and salts. AB - This work provides a comprehensive evaluation of the effect of the cation alkyl side chain length of the 1-alkyl-3-methylimidazolium chloride series ([C n C1im]Cl, n = 2-14) of ionic liquids (ILs) on their capability to form aqueous biphasic systems (ABSs) with salts and self-aggregation derived properties. The liquid-liquid phase behavior of ternary systems composed of [C n C1im]Cl, water, and K3PO4 or K2CO3 and the respective Setschenow salting-out coefficients (ks ), a quantitative measure of the two-phase formation ability, were determined. An odd-even effect in the ks values along the number of methylene groups of the longest IL cation alkyl side chain was identified for the ABS formed by K2CO3, a weaker salting-out agent where the phenomenon is clearly identified. In general, cations with even alkyl side chains, being likely to display higher molar volumes, are more easily salted-out and thus more prone to undergo phase separation. The odd-even effect in the ks values is, however, more significant in ILs up to n = 6, where the nanostructuration/nanosegregation of ILs plays a less relevant role. Still, with the [C n C1im]Cl (n = 7-14) series of ILs, an odd-even effect was also identified in the ILs' ionization degree, molar conductivity, and conductivity at infinite dilution. In summary, it is shown here that the ILs' odd even effect occurs in IL aqueous solutions and not just in neat ILs, an already well-established phenomenon occurring in a series of ILs' properties described as a result of the orientation of the terminal methyl groups to the imidazolium ring cation and consequent effect in the ILs' cohesive energy. PMID- 30283159 TI - Projecting potential spatial and temporal changes in the distribution of Plasmodium vivax and Plasmodium falciparum malaria in China with climate change. AB - Background: Global climate change is likely to increase the geographic range and seasonality of malaria transmission. Areas suitable for distribution of malaria vectors are predicted to increase with climate change but evidence is limited on future distribution of malaria with climate in China. Objective: Our aim was to assess a potential effect of climate change on Plasmodium vivax (P. vivax) and Plasmodium falciparum (P. falciparum) malaria under climate change scenarios. Methods: National malaria surveillance data during 2005-2014 were integrated with corresponding climate data to model current weather-malaria relationship. We used the Generalized Additive Model (GAM) with a spatial component, assuming a quasi Poisson distribution and including an offset for the population while accounting for potential non-linearity and long-term trend. The association was applied to future climate to project county-level malaria distribution using ensembles of Global Climate Models under two climate scenarios - Representative Concentration Pathways (RCP4.5 and RCP8.5). Results: Climate change could substantially increase P. vivax and P. falciparum malaria, under both climate scenarios, but by larger amount under RCP8.5, compared to the baseline. P. falciparum is projected to increase more than P. vivax. The distributions of P. vivax and P. falciparum malaria are expected to increase in most regions regardless of the climate scenarios. A high percentage (>50%) increases are projected in some counties of the northwest, north, northeast, including northern tip of the northeast China, with a clearer spatial change for P. vivax than P. falciparum under both scenarios, highlighting potential changes in the latitudinal extent of the malaria. Conclusion: Our findings suggest that spatial and temporal distribution of P. vivax and P. falciparum malaria in China will change due to future climate change, if there is no policy to mitigate it. These findings are important to guide the malaria elimination goal for China. PMID- 30283161 TI - Soil organic matter widens the range of water contents for tillage. AB - The effects of soil organic matter on the water contents for tillage were investigated by sampling soils with a uniform texture, but a range of soil organic carbon (SOC) from two long-term field experiments at Highfield in Rothamsted Research, UK and Askov Experimental Station, Denmark. The treatments studied in Highfield were Bare fallow (BF), Continuous arable rotation (A), Ley arable (LA) and Grass (G); and in Askov: unfertilized (UNF), 1/2 mineral fertilizer (1/2 NPK), 1 mineral fertilizer (1NPK), and 11/2 animal manure (11/2AM). Minimally disturbed soil cores (100 cm3) were sampled per plot in both locations from 6 to 10 cm depth to generate water retention data. Soil blocks were also sampled at 6-15 cm depth to determine basic soil properties and to measure soil aggregate strength parameters. The range of soil water contents appropriate for tillage were determined using the water retention and the consistency approaches. SOC content in Highfield was in the order: G > LA = A > BF, and in Askov: 11/2 AM > 1NPK = 1/2NPK > UNF. Results showed that different long-term management of the silt loam Highfield soil, and fertilization of the sandy loam Askov soil affected the mechanical properties of the soils- for Highfield soil, aggregates from the G treatment were stronger in terms of rupture energy when wet (-100 hPa matric potential) than the BF treatment. As the soil dried (-300 and -1000 hPa matric potentials), soil aggregates from the G treatment were relatively weaker and more elastic than the BF soil. Our study showed, for both Highfield and Askov soils, a strong positive linear increase in the range of water contents for tillage with increasing contents of SOC. This suggests that management practices leading to increased SOC can improve soil workability by increasing the range of water contents for tillage. We recommended using the consistency approach over the water retention approach for determining the range of water contents for tillage because it seems to give realistic estimates of the water contents for tillage.

AB - When measuring animals' valenced behavioural responses to stimuli, the Conditioned Place Preference (CPP) test goes a step further than many approach based and avoidance-based tests by establishing whether a learned preference for, or aversion to, the location in which the stimulus was encountered can be generated. We designed a novel, four-chambered CPP test to extend the capability of the usual CPP paradigm to provide information on four key features of animals' affective responses: valence, scale, persistence and generalization. Using this test, we investigated the affective responses of domestic chickens (Gallus gallus domesticus) to four potentially aversive stimuli: 1. Puffs of air; 2. Sight of (robotic) snake; 3. Sprays of water; 4. Sound of conspecific alarm calls. We found conditioned avoidance of locations associated with the air puffs and water sprays (Friedman's chi2 (3) = 13.323 p > .005; chi2 (3) = 14.235 p > .005), but not with the snake and alarm calls. The scale of the learned avoidance was similar for the air puff and water spray stimuli, but persistence and generalization differed. We conclude that the four chambered CPP test can have a valuable role to play in making multi-feature measurements of stimulus-generated affective responses, and we highlight the value of such measurements for improving our understanding of the structure of affect in chickens and other animals. PMID- 30283160 TI - Reactive oxygen species, oxidative signaling and the regulation of photosynthesis. AB - Reduction-oxidation (redox) reactions, in which electrons move from a donor to an acceptor, are the functional heart of photosynthesis. It is not surprising therefore that reactive oxygen species (ROS) are generated in abundance by photosynthesis, providing a plethora of redox signals as well as functioning as essential regulators of energy and metabolic fluxes. Chloroplasts are equipped with an elaborate and multifaceted protective network that allows photosynthesis to function with high productivity even in resource-limited natural environments. This includes numerous antioxidants with overlapping functions that provide enormous flexibility in redox control. ROS are an integral part of the repertoire of chloroplast signals that are transferred to the nucleus to convey essential information concerning redox pressure within the electron transport chain. Current evidence suggests that there is specificity in the gene-expression profiles triggered by the different ROS signals, so that singlet oxygen triggers programs related to over excitation of photosystem (PS) II while superoxide and hydrogen peroxide promote the expression of other suites of genes that may serve to alleviate electron pressure on the reducing side of PSI. Not all chloroplasts are equal in their signaling functions, with some sub-populations appearing to have better contacts/access to the nucleus than others to promote genetic and epigenetic responses. While the concept that light-induced increases in ROS result in damage to PSII and photoinhibition is embedded in the photosynthesis literature, there is little consensus concerning the extent to which such oxidative damage happens in nature. Slowly reversible decreases in photosynthetic capacity are not necessarily the result of light-induced damage to PSII reaction centers. PMID- 30283164 TI - Possible Bias in the Publication Trends of High Impact Factor Anesthesiology and Gastroenterology Journals -An Analysis of 5 Years' Data. AB - Background: We hypothesize that being an editorial board member (EBM) in a high impact factor specialty medical journal increases the chances of publishing in the same journal. Materials and Methods: The publication trends of the first five EBMs in the five highest impact factor Anesthesiology and Gastroenterology journals were analyzed. Preceding 5 years' publications appearing on PubMed were grouped into as follows: number of publications in the journal in which the EBM serves (N1), number of publications by the same author in the other four highest impact factor (IF) journals (N2) and number of publications in all the other journals (N3). We evaluated the probability of the observed distribution of publications in the five highest IF journals happening by chance alone, assuming that all the EBMs had the same opportunity of publishing in any of these journals. The probability of publishing in their own journal was assumed to be one fifth. Results: The EBMs published their manuscripts in their own journal at a very high frequency. Encompassing all ten journals, the calculated P value for such a distribution was <0.001. In two journals, Anesthesia and Analgesia and Anaesthesia, the EBMs' publications in their journal were more than twice the cumulative total in the remaining four journals. In three of the five gastroenterology journals analyzed, combined publications of the five EBMs were greater in their own journal than the remaining four journals combined. Conclusions: Despite proclaimed fair peer review process, EBMs seem to get preference in their own journals. PMID- 30283165 TI - Intraoperative Meditation Music as an Adjunct to Subarachnoid Block for the Improvement of Postoperative Outcomes Following Cesarean Section: A Randomized Placebo-controlled Comparative Study. AB - Context: Music therapy is a nonpharmacological modality which can provide promising results for postcesarean section recovery. Aims: The aim of this study was to compare the effects of two types of intraoperative meditation music with control group on postcesarean section pain, anxiety, nausea, vomiting, and psychological maternal wellbeing. Settings and Design: A prospective, randomized, controlled study was conducted on 189 patients. Patients and Methods: The inclusion criteria were the American Society of Anaesthesiologists physical status classes 1E and 2E women aged over 18 years posted for emergency cesarean section under spinal anesthesia. The exclusion criteria were patients with hearing/ear abnormalities and psychiatric disorders. Patients were randomly allocated into three groups - soothing meditation music (M) group, binaural beat meditation music (B) group, and control (C) group - where no music was played. After intervention, data were collected and statistically analyzed. Statistical Analysis Used: Student's t-test was applied for calculation of normative distribution and Mann-Whitney U-test for nonnormative distribution. Nominal categorical data between the groups were compared using Chi-squared test. P <0.05 indicated a statistically significant difference. Results: Both intraoperative meditation music groups had statistically significant less postoperative pain and anxiety and a better overall psychological wellbeing as compared to the control. There was no statistically significant difference in the occurrence and severity of postoperative nausea and vomiting across all three groups. Conclusions: Intraoperative meditation music as good adjunct to spinal anesthesia can improve a cesarean section patient's postoperative experience by reducing postoperative pain, anxiety, and psychological wellbeing. PMID- 30283166 TI - Inhalation of Ketamine in Different Doses to Decrease the Severity of Postoperative Sore Throat in Surgeries under General Anesthesia Patients. AB - Context: Postoperative sore throat (POST) occurs in 21%-65% of patients. Nebulization of ketamine reduces POST. Aims: The aim of this study is to see the effectiveness of nebulized ketamine in different doses to reduce POST and observe adverse effects, if any. Settings and Design: This was a prospective, randomized, and double-blind controlled trial. One hundred and fifty patients of the American Society of Anesthesiologists physical status Classes I and II, in the age group of 18-60 years, of either sex, undergoing surgery under general anesthesia were randomized into three groups. Subjects and Methods: Patients had nebulized with 5 ml solution (Group K1 - 1 ml of ketamine [50 mg/ml] +4 ml normal saline, Group K2 - 0.5 ml of ketamine [50 mg/ml] +4.5 normal saline, and Group S - 5 ml normal saline). Preoperative, intraoperative, and postoperative hemodynamic monitoring was done. The POST monitoring was done at 2, 4, 8, 12, and 24 h postoperatively. POST was graded on a four-point scale (0-3). Statistical Analysis Used: Chi square test using MSTAT software for POST and ANOVA test using INDOSTAT software for hemodynamics were used in this study. Results: The overall incidence of POST in the present study was 29.33% (44/150). In Group S, the incidence of POST was observed to be 46% (23/50). In Group K1, the incidence was 20% (10/50), and in Group K2, it was 22% (11/50) (P <= 0.05), and intraoperative vital signs were more stable at all time intervals. Conclusions: We concluded that both doses (25 and 50 mg) of nebulized ketamine were almost equally effective in preventing POST, with no adverse effects. PMID- 30283167 TI - Comparison of Postoperative Quality of Recovery and Pain Relief with Preoperative Single-Dose Dexamethasone and Lignocaine after Laparoscopic Cholecystectomy. AB - Aim: To compare the role of single intravenous (IV) bolus of lignocaine and dexamethasone on pain score and quality of recovery score (QoR40) after laparoscopic cholecystectomy. Setting and Design: The study was conducted at the postoperative recovery area, This was a double-blind randomized controlled study. Materials and Methods: Seventy patients 18-60 years of age, American Society of Anesthesiologists physical status Class I and II, who underwent elective laparoscopic cholecystectomy, were enrolled in this study after approval from the Institutional Ethics Committee. Patients were randomly allocated to two groups. Group 1 received: 2 mg/kg lignocaine diluted to 10 ml with normal saline, and Group 2 received 0.1 mg/kg IV dexamethasone diluted to 10 ml with normal saline. Global QoR-40 is a 40-item questionnaire that provides a global score and subscores across five dimensions: psychological support, comfort, independence, pain, and emotions. It was assessed on a preoperative day as baseline to assess patient's basic quality of life and at 24 h postoperative. Visual analog scale (VAS) static and dynamic, total analgesic consumption in a day, nausea and vomiting, and antiemetic per day were assessed. Statistical Analysis Used: Student's t-test, Chi-square test, Fisher's exact, Levene's test were used for statistical analysis. Results: Dexamethasone group had higher Global QoR-40 than lignocaine group 187.94 versus 182.85. Among dimensions of QoR-40, dexamethasone had statistically better physical comfort, physical independence, and pain relief as compared to lignocaine. Dexamethasone group had lower VAS compared to lignocaine group. Similarly, there was less fentanyl consumption in dexamethasone group (364.08 +/- 127.31) in the postoperative period when compared to the lignocaine group (412.31 +/- 147.8). Conclusions: Preoperative administration of a single dose of dexamethasone enhanced QoR after laparoscopic cholecystectomy as compared to lignocaine bolus dose. PMID- 30283168 TI - Comparison of Palonosetron with Granisetron for Prevention of Postoperative Nausea and Vomiting in Patients Undergoing Laparoscopic Abdominal Surgery. AB - Background: In patients undergoing laparoscopic surgeries, postoperative nausea and vomiting (PONV) is a serious concern. With an incidence of 46%-72%, PONV hampers the postoperative recovery in spite of the availability of many antiemetic drugs. The purpose of this study was to prospectively evaluate the efficacy of palonosetron and granisetron for the prevention of PONV in patients undergoing laparoscopic abdominal surgery. Aims: The aim of this study was to evaluate and compare the efficacy of palonosetron and granisetron in preventing PONV and to compare the duration of action and side effects in patients undergoing laparoscopic abdominal surgery under general anesthesia. Settings and Design: Eighty patients who were comparable in all aspects were considered for this study. After their consent, they participated in this prospective, randomized, double-blinded, comparative study. Materials and Methods: In this observational study, 80 patients of either gender who were undergoing laparoscopic abdominal surgery under general anesthesia were enrolled in the study. Based on computer randomization, these patients were divided equally into two groups of 40 patients each in double-blinded manner. The treatments were given intravenously 5 min before induction of anesthesia. The episodes of PONV, severity of nausea/vomiting, and side effects were observed during the first 48 h after surgery. Statistical Tests: At the end of study, results were compiled and SPSS(r) statistical package version 18.0 (SPSS Inc., Chicago, IL, USA). Two independent samples t-test was used for quantitative data, and Chi-square or Fisher's exact test was used for qualitative data. P < 0.05 was considered significant. Results: The incidence of PONV during 0-2 h in the postoperative period was 15% with palonosetron and 27.5% with granisetron; the incidence during 2-24 h postoperatively was 20% with palonosetron and 30% with granisetron. Both palonosetron and granisetron had comparable effectiveness as antiemetic during the early postoperative periods (0-24 h). During 24-48 h, the incidence was 17.5% and 37.5%, respectively (P = 0.04). Safety profile was similar in both the groups (P = 0.6). Conclusion: There were no significant differences in the overall incidence of PONV and complete responders for palonosetron and granisetron group in the early recovery period. However, due to its prolonged duration of action, palonosetron was more effective than granisetron for long-term prevention of PONV after laparoscopic abdominal surgery.

AB - Background: Caudal block is the most commonly used regional anesthetic technique in pediatric surgeries; different additives have been used for better and safer outcome. Aim: The aim of this study is to compare the combination of dexamethasone and dexmedetomidine as adjuvants to bupivacaine versus using each agent solely with bupivacaine in pediatric caudal block as regards their efficiency in pain relief (the duration of postoperative analgesia, first time to request analgesia, and modified objective pain score [MOPS]). Study Design: This was a prospective, double-blinded, randomized study. Patients and Methods: Patients and Methods: Sixty-three children scheduled for hypospadias surgery wererandomized into three groupsaccording to the adjuvant drug added to caudal bupivacaine : Group I (n = 21): dexamethasone 0.1 mg/kg + 0.5 mg/kg bupivacaine 0.25%, Group II (n = 21): dexmedetomidine0.01 MUg/kg + 0.5 mg/kg bupivacaine 0.25% and Group III (n = 21): dexamethasone 0.1 mg/kg + dexmedetomidine 0.01 MUg/kg + 0.5 mg/kgbupivacaine 0.25%. Intraoperative and postoperative hemodynamics were recorded. In postoperative anesthesia care unit and then the ward, MOPS and sedation score were recorded at 30 min and 1, 2, 3, 6 and 12 h. Further, the time of first analgesic request and side effects were recorded. Statistical Analysis: Categorical data were presented as frequencies (%) and analyzed using Chi-square test. Continuous data were presented as mean (standard deviation) and median (quartiles). Continuous data were analyzed using one-way analysis of variance for single measures and two-way mixed model for repeated measures. Kaplan-Meier analysis was performed for the duration of analgesia. Results: In Group III, MOPS was lower than Groups I and II at the study times. Further, Group III had prolonged time for first request of analgesic. Sedation scores were prolonged in Group III and Group II than in Group I. There was a reduction in heart rates in Group III more than Group I and Group II but with no significant difference. However, there was a significant reduction in mean arterial blood pressure 30 min intraoperatively and postoperatively in Group III as compared to Groups I and II. Conclusion: The addition of combined dexmedetomidine at a dose of 1 MUg/kg and dexamethasone 0.1 mg/kg to caudal bupivacaine seemed to be an attractive alternative to each drug if used alone with more prolonged analgesia and almost no adverse effects. PMID- 30283170 TI - Practice of Labor Analgesia among Anesthesiologists Across India: Cross-sectional Study. AB - Background: The practice of labor analgesia is an essential part of standard obstetric care. There are many guidelines and programs, which have been setup in labor pain management, in the developed country. In India, the practice of labor analgesia is not very popular. The role of labor analgesia providers lies in educating the parturients about the need of labor analgesia and also to develop comprehensive programs and guidelines in providing it. Aim: The aim of our study was to assess knowledge and practice of labour analgesia among anaesthesiologists across India. Methods: Survey was carried out using SurveyMonkey, an online internet website. Questionnaires were sent by mail to 11,986 anesthesiologists. The questions were based on methods of labor analgesia practice, regional analgesia techniques, commonly used drugs, complications and myths surrounding labor analgesia. Statistical Analysis: Responses were compiled and data was analysed. Results were expressed as percentages. Results: There were 1351 responses to the survey. Labor analgesia was practiced mainly by anesthesiologists across India (71.34%, n = 945). Regional analgesia techniques were the most common techniques followed in providing labor analgesia (69.61%, n = 940) and among regional analgesia techniques, epidural analgesia (43.52%, n = 588) was the most common method. Bupivacaine was considered the drug of choice (64.10% n = 866) and Fentanyl was the standard adjuvant used (83.34% n = 1126). Majority of the respondents did not believe in myths surrounding labor analgesia. Conclusion: Epidural analgesia is the most common technique practiced, bupivacaine the commonly used local anaesthetic, fentanyl common adjuvant used in practice of labour analgesia by anaesthesiologists across India. PMID- 30283171 TI - Comparison of Effects of Oral Melatonin with Oral Alprazolam used as a Premedicant in Adult Patients Undergoing Various Surgical Procedures under General Anesthesia: A Prospective Randomized Placebo-Controlled Study. AB - Background and Aims: Preoperative anxiety is a major concern in patients undergoing any surgical procedure. Various drugs have been used to alleviate it. This study aims to compare the effects of oral melatonin versus oral alprazolam on preoperative anxiety, sedation, orientation, and cognitive function. Materials and Methods: A total of 90 adult patients were randomly allocated into three groups. Group M (n = 30) received oral melatonin 3 mg (2 tablets); Group A (n = 30) received oral alprazolam 0.25 mg (2 tablets), and Group P (n = 30) received placebo, multivitamin tablet (2 tablets) as premedication. The objectives of our study were to compare anxiety, sedation, orientation, and cognitive function using visual analog scale (VAS) anxiety score, Ramsay Sedation Score (RSS), orientation score, and Digit symbol substitution test (DSST) score before and after 120 min of giving premedication. For statistical analysis, paired t-test, Chi-square test, analysis of variance, and post hoc bonferroni test were used. Results: Mean VAS scores for anxiety (after 120 min) were significantly reduced in Group M (3.9 +/- 1.53) and Group A (4.43 +/- 1.67) when compared to Group P (4.73 +/- 0.82) (P < 0.05). RSS was higher in Group A as compared to Group M and Group P (P < 0.05). No significant difference in orientation score was observed in all the three groups before and after premedication (P > 0.05). DSST score (cognitive function) was better in Group M when compared to both Group A and Group P (P < 0.05). Conclusion: Oral melatonin (6 mg) when used as a premedicant is an effective alternative to alprazolam regarding providing better anxiolysis, lesser sedation along with maintenance of cognitive, and psychomotor function. PMID- 30283172 TI - Comparative Efficacy and Safety of Intravenous Clonidine and Tramadol for Control of Postspinal Anesthesia Shivering. AB - Background: Shivering is a common problem in patients undergoing surgery under spinal anesthesia. Aims: The aim of this study was to compare efficacy and safety of clonidine versus tramadol in postspinal anesthesia shivering. Settings and Design: This prospective, randomized, double-blind controlled clinical trial was conducted in a tertiary care setting. Materials and Methods: A total of 60 American Society of Anesthesiologists physical status Class l and II adult patients (age 18-65 years) undergoing surgery under spinal anesthesia and developed shivering received either clonidine 1 MUg/kg or tramadol 1 mg/kg intravenously. The time required for cessation of shivering, control and recurrence rate of shivering, effect on hemodynamics and side effects were compared between two groups. Statistical Analysis: Unpaired t-test and Chi-square test were used for comparison of continuous variables and dichotomous data between two groups, respectively. P < 0.05 was considered as statistically significant. Results: Time for cessation of shivering was less in clonidine group than tramadol group (02.51 vs. 04.82 min; P < 0.001). Complete control of shivering was achieved in 80% of patients in clonidine group versus 70% in tramadol group. There was no significant difference for control (P = 0.5) and rate of recurrence of shivering between clonidine and tramadol group (06.7% vs. 16.7%; P = 0.42). Pulse rate and systolic blood pressure were significantly lower in clonidine group at 5 and 15 min as compared with tramadol. Significantly more number of patients experienced nausea and dizziness (36.7% vs. 0%; P < 0.001 and 20% vs. 0%; P = 0.01) with tramadol while bradycardia and hypotension were numerically more common in patients receiving clonidine (6.7% vs. 0% and 13.3% vs. 0%). Conclusion: Clonidine provides early relief from shivering than tramadol with fewer side effects in patients undergoing surgery under spinal anesthesia. PMID- 30283173 TI - A Study to Compare the Analgesic Efficacy of Dexmedetomidine and Fentanyl as Adjuvants to Levobupivacaine in Ultrasound-Guided Supraclavicular Brachial Plexus Block. AB - Background: Supraclavicular brachial plexus provides complete and reliable anesthesia for upper limb surgeries. Adjuvants are added to local anesthetists to improve various block characteristics. There are limited studies comparing the efficacy of dexmedetomidine and fentanyl as an adjuvant to levobupivacaine. Aims: The aim of the study was to evaluate and compare the effect of dexmedetomidine versus fentanyl as an adjuvant with levobupivacaine in ultrasound-guided supraclavicular brachial plexus block. Settings and Design: This study design was a prospective, randomized, double-blind controlled study. Subjects and Methods: A total of 120 patients in the age group of 30-55 years with physical status American Society of Anesthesiologists Classes I and II undergoing elective upper limb surgeries under ultrasound-guided supraclavicular brachial plexus block were randomly divided into three groups of forty each after taking informed consent and approval from Hospital Ethics Committee: Group A received 25 ml of 0.5% levobupivacaine with 5 ml normal saline (NS). Group B received 25 ml of 0.5% levobupivacaine with 1 MUg/kg dexmedetomidine diluted to the volume of 5 ml NS. Group C received 25 ml of 0.5% levobupivacaine with 1 MUg/kg fentanyl diluted to the volume of 5 ml NS. Onset and duration of sensory and motor block and duration of analgesia were noted and any side effects were observed. Statistical Analysis: The distribution of variables tested with Shapiro-Wilk test. Group comparison of values was made by Kruskal-Wallis test followed by Mann-Whitney test. Results: There was fastest onset time as well as longer duration of sensory and motor block in dexmedetomidine group, intermediate in fentanyl group as compared to levobupivacaine group. Conclusion: This study concludes that addition of dexmedetomidine to levobupivacaine for supraclavicular brachial plexus block shortens the onset time and prolongs the duration of sensory and motor blockade as compared to the addition of fentanyl. PMID- 30283174 TI - Efficacy of Combination of Esmolol and Diltiazem for Attenuating Hemodynamic Response to Laryngoscopy and Intubation: A Prospective Randomized Study. AB - Background: Laryngoscopy and tracheal intubation (LTI) are known to release catecholamines resulting in rise in heart rate (HR) and blood pressure. Various drugs have been studied till date to attenuate the sympathomimetic effects of laryngoscopy and intubation. Aims: The aim is to study the effect and safety of esmolol, diltiazem, and their combination on pressor response of laryngoscopy and intubation. Setting and Design: This prospective, randomized double-blind study was designed to assess the efficacy of the combination of esmolol and diltiazem and compare it with esmolol and diltiazem when used alone, for attenuating the pressor response to laryngoscopy and intubation. Materials and Methods: One hundred twenty-four adult patients of physical status American Society of Anesthesiologists Classes I and II posted for elective surgery under general anesthesia requiring endotracheal intubation were randomly allocated (using computer-generated random numbers) into four groups of 31 each, in a double-blind fashion, to receive the test drug, i.e., saline (control), diltiazem (0.2 mg/kg), esmolol (1.5 mg/kg), or a combination (diltiazem [0.1 mg/kg] and esmolol [0.75 mg/kg]). The test drug was administered intravenously as a bolus after 1 min of injecting the muscle relaxant. LTI was performed after 2 min of the test drug. Hemodynamic data - HR, systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) - were recorded at 1 min intervals after induction, until laryngoscopy and intubation, and at 1, 2, 3, 4, 5, and 10 min thereafter. Statistical Analysis: Statistical analysis was performed using one way analysis of variance (ANOVA) for comparison among and between the groups. The Bonferroni's correction was applied when a significant difference was found between groups after applying ANOVA. Results were considered statistically significant at P <= 0.05. Results: In the control and diltiazem groups, a significant increase in HR (P <= 0.05) was observed after laryngoscopy. Esmolol and combination groups were associated with a significant fall in HR after administration of the test drug, and no significant rise was noted after laryngoscopy. HR was significantly less in the combination and esmolol groups as compared to the control till 5 min after LTI. As compared with the control, all the other groups were associated with a fall in SBP after the test dose, and this lasted for 5 min (P < 0.001) after laryngoscopy in the esmolol and combination groups and for 1 min (P < 0.001) in the diltiazem group. All groups were associated with a significant rise in DBP and MAP for 1-2 min after LTI (P < 0.001), except the combination group in which no change was noted. DBP and MAP were significantly less in the combination group as compared to the control, from 1 min after giving the test dose till 5 min (P < 0.001) after LTI. Conclusion: Although esmolol and combination groups were both effective in controlling the increase in HR and SBP, only the combination group was effective in controlling the rise in DBP and MAP after LTI. HR, SBP, DBP, and MAP were significantly less in the combination group as compared to the control till 5 min after LTI. We recommend a combination of esmolol and diltiazem in appropriate doses for effectively attenuating the rise in HR and blood pressure responses during LTI. PMID- 30283175 TI - Assessment of Relationship between Vitamin D Deficiency and Pain Severity in Patients with Low Back Pain: A Retrospective, Observational Study. AB - Background: Vitamin D is associated with musculoskeletal function in our body, and its deficiency is a common health problem all over the world. Low back pain (LBP) is an important health problem in terms of low quality of life, loss of work power, and cost of diagnosis and treatment approaches. Aims: The purpose of this study is to investigate the relationship between pain severity and Vitamin D deficiency in patients who applied to pain polyclinic with LBP. Settings and Design: This was a retrospective, observational study. Subjects and Methods: The files of patients aged between 18 and 70 years who applied to our hospital between January and February 2018 were examined retrospectively by a specialist. Serum 25-hydroxyvitamin D (25(OH)D) level, Visual Analogue Scale (VAS), age, education level, marital status, working status, and body mass index (BMI) values recorded in patient files were included in the study. The limit value of Vitamin D was accepted as 20 ng/mL. Patients were divided into two groups according to their levels of Vitamin D. Patients with serum 25(OH)D levels below 20 ng/mL were considered as the deficiency of Vitamin D (Group 1) and patients with 20 ng/mL and over 20 ng/mL values were considered as normal in terms of Vitamin D (Group 2). Statistical Analysis Used: Descriptive statistical data were presented as mean, standard deviation, numbers, and percentage. There was no difference between the normally distributed group and the non-normally distributed group in terms of vitamin D levels. To compare the frequencies, the Chi-square test was used. To define the linear association between independent variables and Vitamin D level, Spearman's rho correlation coefficients were calculated. Results: The level of Vitamin D was measured in 98 patients aged 18-70 years who applied to our hospital's polyclinic due to LBP during the study period. The deficiency of vitamin was detected in 84 (85.7%) of the patients, while Vitamin D was found in 14 (14.3%) as normal. Groups were similar in terms of age, gender, BMI, educational level, marital status and working status (p> 0.05); however, there was a statistically significant difference between the two groups in terms of VAS score and levels of Vitamin D (P < 0.001 and P < 0.001, respectively). While there was a negative correlation between D vitamin level and VAS score (r = 0.594, P < 0.001), there was no correlation between age, gender, BMI, education level, marital status, and working status (P > 0.05). Conclusions: The deficiency of Vitamin D is often asymptomatic, and also, it can cause bone and muscle pain. In our study, we determined that the severity of pain increased in patients with LBP as the deficiency of Vitamin D increased. For this reason, we recommend to be evaluated the level of Vitamin D in patients with LBP. PMID- 30283176 TI - Study of Wound Instillation Technique for Effective Postoperative Analgesia using Ropivacaine in Lumbar Spine Surgery. AB - Background: Instillation of local anaesthetics over incision site is a simple technique done as a part of multimodal analgesia targetting incisional pain for post-operative pain relief following lumbar laminectomy. Aim: To determine postoperative analgesic effect of ropivacaine in wound instillation for lumbar laminectomy. Study Design: Prospective, randomised, double blind study. Methodology: Forty patients scheduled for elective lumbar laminectomy under general anaesthesia were enrolled and randomly allocated into two groups namely Group R (n=20 receiving 20ml of 0.25% ropivacaine) and Group N (n=20 receiving 20ml normal saline) as instillation over incision site. If the NRS exceeded '4' at any point of time, rescue analgesia with inj. Diclofenac 75 mg deep intramuscular was administered. Post- operative pain score, duration of analgesia and total rescue analgesic required in 24 h were compared between the groups. Results: The pain score was less in ropivacaine group as compared to normal saline group (p value 0.0001). Duration of analgesia in normal saline group (N) is 4.3+/- 1.03 and in ropivacaine group(R) is 12.15+/-1.49. Mean amount of rescue analgesic required in normal saline group was 191.25+/- 38.28mg and in ropivacaine group was 97.5+/- 35.26 mg. Conclusion: The patients who received ropivacaine wound instillation had better pain control, longer duration of analgesia and less analgesic requirement as compared to patients who received normal saline wound instillation. PMID- 30283177 TI - A Study Comparing Propofol Auto-coinduction and Standard Propofol Induction in Patients Undergoing General Anesthesia Without Midazolam Pretreatment: A Prospective Randomized Control Trial. AB - Background: Propofol has emerged as an induction agent of choice over the past two decades due to its quick, smooth induction and rapid recovery. The main concern for an anesthesiologist is the hemodynamic instability caused by the standard induction dose of propofol (2-3 mg/kg). Aim: We aim to study the efficacy of propofol auto-coinduction technique in comparison to the standard propofol induction technique in terms of the total induction dose requirement of propofol, the incidence of hemodynamic side effects and pain on injection, and the incidence of fentanyl-induced cough (FIC) in the absence of a synergistic agent like midazolam. Materials and Methods: This was a prospective, observer blinded, randomized controlled trial. The study was initiated after obtaining the institutional ethics committee approval and is registered in the Clinical Trials Registry India. Eighty American Society of Anesthesiology Physical Status I and II patients, of either sex, aged between 18 and 55 years, and scheduled for elective surgeries under general anesthesia were randomized into two equal groups. Patients allocated to Group I (auto-coinduction) received 20% of the calculated dose of injection propofol 2 mg/kg (i.e., 0.4 mg/kg) as the priming dose followed by injection fentanyl 1 MUg/kg after 1 min and the remaining propofol was administered in titrated doses till loss of verbal response after 2 min. In Group II (control), patients received injection fentanyl 1 MUg/kg followed by single bolus dose of injection propofol up to 2 mg/kg till loss of verbal response. Midazolam was not used for premedication or induction. Intubation was carried out only after ensuring achievement of optimum depth of anesthesia using bispectral index scale. The total dose of propofol administrated for induction, occurrence of pain on injection, severity of cough after fentanyl administration, hemodynamic parameters, and apneic episodes were recorded. Statistical Analysis: All data were expressed as mean +/- 2 standard deviation. For statistical analysis, SPSS software version 16 (SPSS Inc., 2007, Chicago, IL, USA) was used. Results: The mean dose of injection propofol required for induction was significantly lower in Group I (67.0 +/- 17.9 mg) when compared with Group II (111.3 +/- 17.6 mg) (P < 0.01). The mean heart rate was significantly higher (P < 0.01) and the mean blood pressure was significantly lower in Group II (P < 0.01) when compared to Group I at 1 min postinduction, immediately after intubation, and 5 min after induction. The incidence of complications such as hypotension, pain on injection, and FIC was higher in Group II (50%) as compared to Group I (18%). Conclusion: In our study, we found that the induction dose requirement of propofol was significantly lower in the auto coinduction group when compared to the conventional induction group. The auto coinduction technique offered a stable hemodynamic profile, reduced pain on injection, and less incidence of FIC as compared to the conventional propofol induction technique. PMID- 30283178 TI - Comparison of Blind Endotracheal Aspiration and Bronchoscopic Brush Biopsy Sampling Methods for Bacteriological Diagnosis of Ventilator-Associated Pneumonia in Intensive Care Unit. AB - Background: The diagnosis of ventilator-associated pneumonia (VAP) is a challenge because the clinical signs and symptoms lack both sensitivity and specificity. Further confirmation of the diagnosis of VAP can be done by other diagnostic procedures such as bronchoscopic and blind endotracheal aspiration, but the selection of either diagnostic procedure is debatable. Aims: The aim is to study and compare the role of bronchoscopic protected specimen brush biopsy (PSBB) and blind endotracheal aspiration for diagnosis of VAP. Settings and Design: This prospective comparative study was conducted in multidisciplinary Intensive Care Unit of a tertiary care hospital. Materials and Methods: Thirty patients clinically diagnosed to have VAP were further evaluated by bronchoscopic and blind endotracheal aspiration. The P value of PSBB and blind aspiration techniques was calculated, taking clinical pulmonary infection score of >=6 as reference standard. Statistical Analysis Used: Statistical analysis was done using Chi-square and t-test. Results and Conclusions: Our study shows that for the diagnosis of VAP, PSBB and blind aspiration had Chi-square value of 0.83 with degree of freedom 1 which showed P = 0.3623 which is not significant. t-test value is 0.402 with degree of freedom 1 and P = 0.7567 which is still not significant. There was a good microbiologic concordance among bronchoscopic and nonbronchoscopic distal airway sampling techniques. Blind endotracheal aspiration is a comparable technique for bacteriological diagnosis of VAP. PMID- 30283179 TI - Efficacy of Dexmedetomidine Added to Ropivacaine Infilteration on Postoperative Pain following Spine Surgeries: A Randomized Controlled study. AB - Context: With modern lifestyle, there has been a steep increase in the number of low back pain patients in clinical practice. Lumbar microdiscectomy is one of the most common surgeries performed for this problem. Postoperative pain management is extremely important aspect of such advanced surgical technique among which wound infiltration is an efficient method. Aims: The aim of the study was to compare the efficacy of dexmedetomidine added to ropivacaine verses plain ropivacaine following wound infiltration in terms of pain scores, requirement of rescue analgesia, and related adverse effects. Settings and Design: Randomized, prospective, controlled, double-blind study over a period of 1 year in a tertiary care hospital. Materials and Methods: Sixty patients scheduled for lumbar discectomy were randomly allocated into two groups. Group A received wound infiltration with 30 ml 0.2% ropivacaine before wound closure and Group B received wound infiltration with 1ug/kg dexmedetomidine added to 30 ml of 0.2% ropivacaine before wound closure. Data retrieved were demographic data, visual analog scores, postoperative pain scores, rescue analgesia by patient controlled analgesia pump, recovery profile, and adverse effects. Statistical Analysis Used: Data were analyzed using statistical software SPSS version 22. Mann-Whitney test, Kruskal-Wallis test, and Chi-square test were used as applicable. Results: Demographic data were comparable between the groups. Requirement of rescue analgesia was significantly less in Group B where combination of dexmedetomidine and ropivacaine was given. Conclusions: Dexmedetomidine provided effective postoperative analgesia and reduced fentanyl consumption when administered in wound infiltration with ropivacaine. PMID- 30283180 TI - The Effects of the Quincke Spinal Needle Bevel Insertion on Postdural Puncture Headache and Hemodynamics in Obstetric Patients. AB - Aim: Spinal anesthesia is a widely used procedure in modern anesthesia. Although it is a reliable and frequently used anesthetic procedure, it involves complications, including postdural puncture headache caused by arachnoid punctured, which significantly affects postoperative well-being. In this study, we aimed to observe headache frequency with 26-G Quincke spinal needle in either transverse or sagittal planes. Materials and Methods: One hundred patients with American Society of Anesthesiologists status classes I and II who were scheduled for elective cesarean delivery with no contraindications for performing spinal anesthesia were randomly divided into two groups: Group I (transverse n = 50) and Group II (sagittal n = 50). Spinal anesthesia was performed with a 26-G Quincke needle, using 1.5-2.0 ml 0.75% hyperbaric bupivacaine. The anesthesiologists' experience, number of attempts for spinal anesthesia, volume of fluid administered preoperatively and intraoperatively, intervertebral space where spinal anesthesia was administered, and patient movements during the attempts were recorded. Mean arterial pressure and peak heart rates were recorded for 60 min intraoperatively and postoperatively. Headache and back pain complications were observed for 1 week postoperatively. Chi-square tests and statistical comparisons of the rates (statistical significance, P < 0.05) were used for assessments. Results and Conclusions: No significant differences were observed with respect to age, height, weight, headache, or incidence of back pain. No significant differences were observed for the number of spinal attempts, intervertebral space where spinal anesthesia was administered, experience of the anesthesiologists, patient movements during the attempts, volumes of fluid administered preoperatively and intraoperatively, or low back pain incidence. Significant reductions in mean arterial pressure were observed between groups after 10, 15, 30, 40, and 50 min. No significant differences were observed in headache or back pain frequency with 26-G Quincke spinal needle in either transverse or sagittal planes. Hypotension was frequently observed in the transverse group. PMID- 30283181 TI - A Study to Assess the Efficacy of Different Doses of Propofol for Tracheal Intubation: A Randomized Clinical Trial. AB - Background: Tracheal intubation is usually facilitated by using a muscle relaxant to supplement drugs given for the induction of general anesthesia. Nondepolarizing muscle relaxants are also associated with the few disadvantages. Endotracheal intubation under volatile anesthetics without the use of muscle relaxants is possible, but it has disadvantages. Time available for intubation is much less when compared to the use of muscle relaxants. Considering the disadvantages of muscle relaxants and volatile agents in mind, there is a need for endotracheal intubation without muscle relaxants. Objective: The objective of the study is to assess the efficacy of different doses of propofol for tracheal intubation - a randomized clinical trial. Materials and Methods: A randomized study was conducted on 80 patients, comprising of 40 patients each. Patients of either sex were randomly allocated into Group P1 and Group P2 by computer generated random numbers where Group P1 received 2 mg/kg propofol +3 MUg/kg fentanyl and Group P2 received 4 mg/kg propofol +3 MUg/kg fentanyl. SpO2, heart rate, blood pressure (BP)- systolic BP, diastolic BP, and mean arterial pressure were recorded at 1 and 3 min after administration of study drugs were recorded. Intubating conditions were assessed modified Helbo-Hansen scoring system. Results: The success rate of endotracheal intubation was 62.5% and 95% in propofol 2 mg/kg + fentanyl 3 MUg/kg and propofol 4 mg/kg + Fentanyl 3 MUg/kg, respectively. The total incidence of hypotension was 40% and 83% in propofol 2 mg/kg + Fentanyl 3 MUg/kg and propofol 4 mg/kg + Fentanyl 3 MUg/kg, respectively. The incidence of hypersensitivity was noted only in propofol 4 mg/kg + Fentanyl 3 MUg/kg group and was 2.5%. Conclusion: We conclude that endotracheal intubation is possible in premedicated adult American Society of Anesthesiologists by Grade I patients with receiving 3 MUg/kg Fentanyl + 2 mg/kg or 4 mg/kg propofol for induction without muscle relaxants, and the intubating conditions are acceptable. We found that propofol 4 mg/kg + Fentanyl 3 MUg/kg is the optimal dose required for intubation without the use of muscle relaxants. PMID- 30283182 TI - Comparative Study between Magnesium Sulfate and Lidocaine for Controlled Hypotension during Functional Endoscopic Sinus Surgery: A Randomized Controlled Study. AB - Background: Intraoperative bleeding impairs surgical field visibility during functional endoscopic sinus surgery (FESS); several methods have been used to decrease blood loss and improve surgical field, one of them is usage of hypotensive anesthetic agents. Aim: We intended to compare magnesium sulfate with lidocaine, regarding their efficiency in inducing controlled hypotension and providing a better surgical field exposure during FESS and the influence of their usage on extubation time. Settings and Design: This study design was a prospective randomized controlled double-blinded clinical study. Patients and Methods: Eighty adult patients with patients' physical status ASA Classes I and II, aged 20-50 years scheduled for FESS were randomly divided into two study groups; each group contains 40 patients: Group L received lidocaine 2 mg/kg/h with maximum of 200 mg/h starting at induction of anesthesia and continuing until the end of surgery and Group M received an iv bolus of magnesium sulfate 50mg/kg in a total of 100ml saline over 10 min followed by infusion of 15mg/kg/h until the end of surgery; patients were observed for the quality of the surgical field, blood loss, and extubation time. Statistical Analysis Used: Student's t-test or Mann-Whitney's U, Chi-square, or Fisher's exact tests were used. Results: Group L showed a significant decrease in blood loss (P = 0.01), better surgical field clarity (P = 0.002), and shorter extubation time (P = 0.001) than Group M, but there was no statistically significant difference between the two study groups as regards hemodynamics. Conclusion: We concluded that both magnesium sulfate and lidocaine successfully induced controlled hypotension in patients undergoing FEES, but lidocaine provided better surgical field clarity and shorter extubation time. PMID- 30283183 TI - Evaluation of the Metabolic Profile of Ringer Lactate versus Ringer Acetate in Nondiabetic Patients Undergoing Major Surgeries. AB - Background: Stress-induced neuroendocrine and metabolic changes lead to intraoperative hyperglycemia which is related to surgery and the type of intravenous fluids used. Aims: The primary objective was to assess the incidence of hyperglycemia with use of lactate versus acetate-based intravenous fluids in nondiabetics undergoing major surgeries. Incidence of lactatemia and metabolic acidosis were also assessed. Settings and Design: Prospective parallel group observational study conducted in a tertiary care institute. Subjects and Methods: A total of 208 nondiabetic patients undergoing major head and neck free flap or abdominal surgeries were included in the study. Group A received Ringer lactate, and Group B received Ringer acetate as intraoperative maintenance fluid. Intraoperative blood sugar, pH, and lactate levels were monitored. Statistical Tests Used: Chi-square test and independent "t" test were used for analysis. Results: Intraoperative hyperglycemia was more frequent in Group A than B (17.3 vs. 18.4%). Group B patients undergoing gastrointestinal (GI) surgeries showed higher blood glucose at 2, 4, 6, and 8 h when compared to flap surgeries. In Group A, significantly higher blood sugar values were noted at 2 and 8 h in those undergoing GI surgeries. Group B patients undergoing GI surgeries had significantly higher lactate levels at 6 and 8 h. Group B patients had significant acidosis when surgeries lasted >6 h. Conclusion: Nondiabetic patients undergoing major abdominal surgeries who received acetate-based fluids had relatively higher intraoperative blood sugar levels as compared to those receiving lactated solutions, but the incidence of hyperglycemia was comparable. When the duration of surgery exceeded 6 h, acetate-based solutions resulted in significantly higher lactate levels with progressive metabolic acidosis. PMID- 30283184 TI - The Efficacy of Intravenous Magnesium Sulfate versus Intravenous Paracetamol on Children Posttonsillectomy Pain and Analgesic Requirement: A Randomized Controlled Study. AB - Background: One of the most common complications of tonsillectomy is pain, which leading to delayed recovery and later hospital discharge. Aims: We intended to compare the efficacy of magnesium sulfate versus paracetamol on the posttonsillectomy pain and analgesic requirement. Settings and Design: This study design was a prospective randomized controlled double-blinded clinical study. Patients and Methods: A total of 60 children with the American Society of Anesthesiologists physical status classes I and II, aged 3-12 years, scheduled for tonsillectomy were randomly divided into two groups each group contains 30 patients: (Group M): received an initial loading dose of magnesium sulfate 30 mg/kg over 15 min started with induction followed by continuous infusion of 10 mg/kg/h for 1 h regardless of the operation time and (Group P): received paracetamol infusion 10 mg/kg started with induction and continued for 1 h. Postoperatively, a blinded postanesthesia care unit (PACU) nurse observed the quality of analgesia using the face, legs, activity, cry, and consolability pain scores, bleeding, and sedation. Statistical Analysis Used: Student's t-test and Chi-square test were used for analysis. Results: Regarding postoperative pain, there was a statistically significant difference between the two groups at the time of admission in PACU (P = 0.025) as children who experienced pain already had taken rescue analgesic to alleviate pain. There was a statistically significant difference between the two groups regarding the need for analgesics (P = 0.038). There was no statistically significant difference regarding bleeding and sedation scores between the two study groups. Conclusions: Magnesium sulfate provided better postoperative analgesia and reduced need for analgesics after tonsillectomy compared to paracetamol, and regarding the incidence of bleeding and the degree of sedation the outcome in both groups was readily comparable. PMID- 30283185 TI - Use of Butorphanol, Fentanyl, and Ketamine as Co-Induction Agents with Propofol for Laryngeal Mask Airway Insertion: A Comparative Study. AB - Background: Management of airway is of great importance in the practice of anesthesia. Supraglottic airway devices, such as laryngeal mask airway (LMA), have greatly revolutionized the management of airway both in terms of ease and degree of invasiveness. Propofol, by its inherent property of decreasing airway reflexes, is used to aid in LMA insertion. In this study, we have evaluated the LMA insertion conditions and hemodynamic stability, comparing butorphanol, fentanyl, and ketamine as co-induction agents with propofol. Materials and Methods: A total of 90 female patients planned to undergo minor gynecological procedures were randomly allocated to one of the three study groups. Patients in Group B received butorphanol 20 MUg/kg, patients in Group F received fentanyl 1 MUg/kg, and patients in Group K received ketamine 0.5 mg/kg intravenously before injection of propofol 2.5 mg/kg. LMA insertion conditions were graded according to the modified scheme of Lund and Stovner, and hemodynamic parameters were recorded. The results were analyzed statistically. Results: The patients in all the three groups were comparable in their demographic characteristics. The mean total dose of propofol used in Group B was 136.50 mg (standard deviation [SD] 27.70), in Group F was 139.33 mg (SD 28.52), and in Group K was 156.33 mg (SD 38.64). Excellent insertion conditions were observed in 25 (83.3%) patients in Group B, 25 (83.3%) patients in Group F, and 15 (50%) patients in Group K. Group B and Group K showed a more stable hemodynamic profile than Group F. Conclusion: It is concluded that the use of butorphanol as a co-induction agent with propofol provides excellent insertion conditions and stable hemodynamics compared to fentanyl or ketamine. PMID- 30283186 TI - Role of Lignocaine Nebulization as an Adjunct to Airway Blocks for Awake Fiber Optic Intubation: A Comparative Study. AB - Context: Airway management is a crucial skill and area of concern for the anesthesiologist. Awake fiber-optic intubation (AFOI) remains the gold standard in managing difficult airway. Anaesthetizing the airway along with psychological assurance is the mainstay for Preparation of AFOI. Different topical and regional techniques have been developed to subdue reflexes and facilitate AFOI. Aim: This randomized controlled study was performed to evaluate the effectiveness of using lignocaine nebulization in addition to specific airway blocks for AFOI. Methodology: This was a comparative study conducted in 60 patients with difficult airway (LEMON score >2) and randomly allocated into two groups of 30 each. Group LB and Group NB received nebulization of 2% lignocaine 4 mL and 0.9% normal saline 4 mL, respectively. Both groups were then given airway blocks as bilateral superior laryngeal (2% lignocaine 1-2 mL each) and transtracheal (2% lignocaine 4 mL) block. Two puffs of 10% lignocaine to nose and postnasal space on each side were given in both groups. Fiber-optic bronchoscopy (FOB)-guided tracheal intubation was Performed. Vital parameters, side effects, bronchoscopy-guided intubation time and other parameters as intubation grading scale, patient comfort score, satisfaction score were recorded. Chi-square test and unpaired t-test were used for statistical analysis. Results: Statistically, no significant differences were found in hemodynamic parameters, demographics, intubation time, and intubation grading scale in both groups. However, overall patient comfort and satisfaction score was better in Group LB. Conclusion: Upper airway blocks provide adequate anesthesia for awake FOB, but when lignocaine nebulization is added to these blocks, it improves the quality of anesthesia and patient satisfaction. PMID- 30283187 TI - Quadratus Lumborum Block versus Transversus Abdominis Plane Block in Patients Undergoing Total Abdominal Hysterectomy: A Randomized Prospective Controlled Trial. AB - Background: Abdominal hysterectomy is associated with sever postoperative pain. Quadratus lumborum (QL) block is a regional analgesic technique which has an evolving role in postoperative analgesia. Aims: we aimed to compare ultrasound guided bilateral transverse abdominis plane (TAP) block versus bilateral QL block in patients undergoing total abdominal hysterectomy. Settings and Design: This is a prospective randomized controlled double blinded study. Patients and Methods: Sixty adult female patients (ASA I-II), scheduled for total abdominal hysterectomy were randomized into two equal groups (TAP group and QL group). Each patient received general anesthesia plus bilateral TAP block or bilateral QL block. We recorded postoperative total dose of morphine used / 24 hours, Visual Analuge Scales (VAS) for pain (at 30 min, 2, 4, 6, 12, and 24 hours postoperative), duration of postoperative analgesia, total dose of fentanyl use intraoperative, number of patients needed rescue analgesia and any side effects. Statistical Analysis: Independent sample T test and Chi-Square (X2) test were used as appropriate. Results: Patients in QL group consumed significantly less fentanyl and morphine than patients in TAP group, VAS for pain was significant higher in TAP group than in QL group at all times, the duration of postoperative analgesia was shorter in TAP group than in QL group, the number of patients requested analgesia was significantly higher in TAP group than in QL group. Conclusions: Bilateral QL block provided better intraoperative and postoperative analgesia with less opioids consumption compared with bilateral TAP block, in patients undergoing total abdominal hysterectomy. PMID- 30283188 TI - Intranasal Fentanyl, Midazolam and Dexmedetomidine as Premedication in Pediatric Patients. AB - Background: Surgery is a very stressful experience for patients. Children are the most susceptible to fear, anxiety, and stress due to their limited cognitive capabilities and dependency. In children, pharmacologic agents are frequently used as premedication to relieve the fear of surgery, to make child-parental separation easy, and to carry out a smooth induction of anesthesia. We conducted this study to compare the efficacy of intranasal fentanyl, midazolam, and dexmedetomidine as premedication in pediatric patients. Materials and Methods: The present study was conducted prospectively on 75 patients in the age group of 2-6 years of either sex of the American Society of Anesthesiologists physical Class I or II admitted in Guru Nanak Dev Hospital, attached to Government Medical College Amritsar, scheduled to undergo surgery under general anesthesia. The patients were divided into three groups of 25 each. Group F received intranasal fentanyl 1.5 MUg/kg body weight, Group M received intranasal midazolam 0.3 mg/kg body weight, and Group D received intranasal dexmedetomidine 1 MUg/kg body weight as nasal drops 50 min before surgery. Results: Children who received intranasal fentanyl and intranasal midazolam had early onset of anxiolysis and sedation as compared to dexmedetomidine. In child-parent separation, quality of induction was better with fentanyl and dexmedetomidine as compared to midazolam. Intravenous cannulation score was best achieved with fentanyl as premedicant. Postoperative sedation was better with dexmedetomidine as compared to fentanyl and midazolam. Conclusion: Onset of action of fentanyl and midazolam is early as compared to that of dexmedetomidine. However, fentanyl provided better conditions for induction and emergence than midazolam. With dexmedetomidine onset of action was delayed and duration of action was prolonged which helped child to remain calm and sedated even after the surgery. PMID- 30283189 TI - Efficiency and Efficacy of Two Techniques of Preoxygenation during Modified Rapid Sequence Intubation. AB - Background: Apneic mass movement of oxygen by applying continuous positive airway pressure (CPAP) is possible only when the airway is kept patent which helps to reduce the rate of desaturation. Aims: The aim of this study was to check the efficiency of preoxygenation and apneic oxygenation by assessing the drop in partial pressure of arterial oxygen (PaO2) during apnea with and without keeping an oropharyngeal airway to maintain the patency of airway. Settings and Design: This prospective observational study was conducted at a tertiary care center. Materials and Methods: Sixty patients undergoing robotic and laparoscopic assisted surgeries requiring modified rapid sequence intubation were recruited for the study. In Group A, CPAP was not applied during preoxygenation and oropharyngeal airway was not used, but oxygen was administered at 5 L/min during the apnea. In Group B, CPAP of 5 cmH2O was maintained during preoxygenation and after induction an oropharyngeal airway was inserted. Patients in both the groups were induced and paralyzed following standardized anesthesia protocol. Statistical Analysis Used: Chi-square test, independent t-test, and ANCOVA were used as applicable. Results: Group B showed significantly higher mean PaO2 levels after preoxygenation (525.3 +/- 42.5 vs. 500.8 +/- 51) and at 90 s of apnea (494.8 +/- 42.6 vs. 368.6 +/- 98.4) as compared to Group A. The fall in PaO2 was significantly lower in Group B. The rise in partial pressure of arterial carbon dioxide was comparable in both groups. Conclusion: Preoxygenation with CPAP of 5 cmH2O followed by apneic oxygenation with CPAP keeping the airway patent with an oropharyngeal airway results in significantly higher PaO2 after preoxygenation and slower reduction in PaO2 during apnea. PMID- 30283190 TI - Anesthetic Management in Corpus Callosum Agenesis. AB - Corpus callosum agenesis develops when the band which connects the two hemispheres of the brain does not occur in utero. It is associated with prenatal infections, genetic factors, toxic exposures, metabolic disorders, and chromosome errors. Mostly seen clinical features are macrocephaly, microcephaly, seizures, motor retardation, hypotonia, eye anomalies, and facial dysmorphisms. Here, we report a case of corpus callosum agenesis syndrome undergoing upper endoscopy under deep sedation with dexmedetomidine. The main anesthetic concerns are difficulty in airway, respiratory problems, gastric reflux, and interaction of the seizures therapy with general anesthetics. PMID- 30283191 TI - Ultrasound-Guided Taylor's Approach in Ankylosing Spondylitis. AB - Ankylosing spondylitis (AS) is a chronic inflammatory disease of the spine which leads to ossification and formation of a classical bamboo spine. This poses a challenge to the anesthetist both in terms of administering general and regional anesthesia due to the limited mobility of the spine. With the advent of ultrasound as an aid in regional anesthesia, it has been relatively easy to perform a central neuraxial blockade in such patients though the skill requires some degree of expertise. Here, we have described the use of ultrasound as a guide for administering regional anesthesia to a patient with AS after initially attempting a blind approach which had failed due to difficult anatomy. PMID- 30283192 TI - Unilateral Acute Respiratory Distress Syndrome with Contralateral Pulmonary Artery Agenesis: A Rare Scenario. AB - Unilateral pulmonary artery agenesis (UPAA) is a rare condition where the patient may remain asymptomatic for a long period till adulthood. Presentation may be in the form of dyspnea, cough, hemoptysis, decreased exercise tolerance, and recurrent respiratory tract infections. Ventilation-perfusion mismatch and excessive blood flow to the normal lung may eventually lead to unilateral acute respiratory distress syndrome (ARDS). We present a case of a 40-year-old gentleman with nonresolving pneumonia who was diagnosed to have unilateral ARDS due to UPAA. Even though ARDS involves bilateral lung, unilateral ARDS which does not show resolution with lung protective strategies should always raise the suspicion of a rare disease like UPAA among clinicians. To date, there is no specific prescribed treatment for UPAA.

AB - [This retracts the article on p. 921 in vol. 11, PMID: 29284850.]. PMID- 30283194 TI - Influence of oat components on lipid digestion using an in vitro model: Impact of viscosity and depletion flocculation mechanism. AB - Depletion flocculation is a well-known instability mechanism that can occur in oil-in-water emulsions when the concentration of non-adsorbed polysaccharide exceeds a certain level. This critical flocculation concentration depends on the molecular characteristics of the polysaccharide molecules, such as their molecular weight and hydrodynamic radius. In this study, a range of analytical methods (dynamic shear rheology, optical microscopy, and static light-scattering) were used to investigate the interaction between lipid droplets and polysaccharides (guar gum and beta-glucans) of varying weight-average molecular weight and hydrodynamic radius, and concentration. The aim of this work was to see if the health benefits of soluble fibers like beta-glucans could be explained by their influence on the structure and digestibility of lipid emulsions. The apparent viscosity of the emulsions increased with increasing polysaccharide concentration, molecular weight, and hydrodynamic radius. Droplet flocculation was observed in the emulsions only at certain polysaccharide concentrations, which was attributed to a depletion effect. In addition, the water-soluble components in oat flakes, flour, and bran were extracted using aqueous solutions, to examine their impact on emulsion stability and properties. Then, the rate and extent of lipolysis of a sunflower oil-in-water emulsion in the presence of these oat extracts were monitored using the pH-stat method. However, the inhibition of lipolysis was not linearly related to the viscosity of the oat solutions. The water-soluble extracts of beta-glucan collected from oat flakes had a significant inhibitory effect on lipolysis. The results of this study increase our understanding of the possible mechanisms influencing the impact of oat constituents on lipid digestion. This work also highlights the importance of considering the molecular properties of polysaccharides, and not just their impact on solution viscosity. PMID- 30283195 TI - SHIFT: speedy histopathological-to-immunofluorescent translation of whole slide images using conditional generative adversarial networks. AB - Multiplexed imaging such as multicolor immunofluorescence staining, multiplexed immunohistochemistry (mIHC) or cyclic immunofluorescence (cycIF) enables deep assessment of cellular complexity in situ and, in conjunction with standard histology stains like hematoxylin and eosin (H&E), can help to unravel the complex molecular relationships and spatial interdependencies that undergird disease states. However, these multiplexed imaging methods are costly and can degrade both tissue quality and antigenicity with each successive cycle of staining. In addition, computationally intensive image processing such as image registration across multiple channels is required. We have developed a novel method, speedy histopathological-to-immunofluorescent translation (SHIFT) of whole slide images (WSIs) using conditional generative adversarial networks (cGANs). This approach is rooted in the assumption that specific patterns captured in IF images by stains like DAPI, pan-cytokeratin (panCK), or alpha smooth muscle actin ( alpha-SMA) are encoded in H&E images, such that a SHIFT model can learn useful feature representations or architectural patterns in the H&E stain that help generate relevant IF stain patterns. We demonstrate that the proposed method is capable of generating realistic tumor marker IF WSIs conditioned on corresponding H&E-stained WSIs with up to 94.5% accuracy in a matter of seconds. Thus, this method has the potential to not only improve our understanding of the mapping of histological and morphological profiles into protein expression profiles, but also greatly increase the e ciency of diagnostic and prognostic decision-making.

The most of the angiomyolipomas are asymptomatic and found incidentally with ultrasound. They are more prevalent in patients with tuberous sclerosis. It is very important to make differential diagnosis from other renal neoplasm such as renal cell carcinoma. Growth rate is higher among pregnant women suggest that the hormones may play a role in the stimulation of angiomyolipoma. The most common serious presentation is rupture and hemorrhage, and sometimes it can lead to shock. Adequate diagnosis, treatment, and follow-up are very important in the face of renal angiomyolipoma. PMID- 30283197 TI - Chemical Items Used for Preparing Tissue-Mimicking Material of Wall-Less Flow Phantom for Doppler Ultrasound Imaging. AB - The wall-less flow phantoms with recognized acoustic features (attenuation and speed of sound), interior properties, and dimensions of tissue were prepared, calibrated, and characterized of Doppler ultrasound scanning demands tissue mimicking materials (TMMs). TMM phantoms are commercially available and ready made for medical ultrasound applications. Furthermore, the commercial TMM phantoms are proper for ultrasound purpose or estimation of diagnostic imaging techniques according to the chemical materials used for its preparation. However, preparing a desirable TMM for wall-less flow phantom using a specific chemical material according to the specific applications is required for different flow. In this review, TMM and wall-less flow phantoms prepared using different chemical materials and methods were described. The chemical materials used in Doppler ultrasound TMM and wall-less flow phantoms fabricated over the previous decades were of high interest in this review. PMID- 30283198 TI - The Most Appropriate Time Delay after Microbubble Contrast Agent Intravenous Injection to Maximize Liver Metastasis Conspicuity on Contrast-Enhanced Ultrasound. AB - Purpose: To identify the most appropriate time delay after microbubble contrast agent injection to maximize liver metastasis conspicuity on contrast-enhanced ultrasound (CEUS). Methods: Twenty-five consecutive patients (12 male and 13 female; age: 50 +/- 13 years) with a known primary tumor and evidence of liver metastases on unenhanced ultrasound (US) underwent CEUS. CEUS consisted of continuous liver parenchyma scanning during arterial (15-35 s after microbubble injection), portal venous (40-120 s), and late phase (from 120 s up to microbubble disappearance). Subjective conspicuity index (ranging from 1 to 5) and objective conspicuity index (Ilesion-Iliver/Iliver, I = signal intensity) were calculated on reference frames selected on arterial phase and every 20 s on portal venous and late phase. Results: A total number of 40 liver metastases were identified after microbubble injection. The highest liver metastasis conspicuity was observed on early portal venous phase (40-60 s after microbubble injection) both on visual (mean subjective conspicuity index +/- standard deviation [SD] = 4.36 +/- 0.75, reader 1; 4.25 +/- 0.65, reader 2) and quantitative analysis (mean objective conspicuity index +/- SD = -0.99 +/- 0.001). Conclusion: The early portal venous phase (40-60 s after microbubble injection) provides the best liver metastases' conspicuity after microbubble contrast agent injection. PMID- 30283199 TI - A New Scatter Particle and Mixture Fluid for Preparing Blood Mimicking Fluid for Wall-Less Flow Phantom. AB - Background: To examine the blood flow and detection of the issues related to it by medical ultrasound, it is extremely important to have suitable blood mimicking fluid (BMF) to be used in vitro and to have a movable or portable Doppler flow phantom to use it as a standardizing tool. As known, the main drawbacks of the currently commercial BMF used in the research studies are high in cost and the long time needed for preparation, which is at least 5-7 h. Moreover, there are only two common scatter particles using in BMF as suspension materials such as nylon (Orgasol) and polystyrene. Thus, we need to prepare BMF with both a new mixture fluid and new scatter particle to be as a reflecting factor of ultrasonic waves, for evaluating the speed of sound of the blood flow in the same method like in the research study of ultrasound with relatively low-cost and less consuming time of preparation. However, both the acoustical and physical features of the Doppler flow phantom components (BMF and tissue mimicking material) must correspond the features of the human tissues to make the examination significance. In addition, the BMF must also represent the hemodynamic features of real human blood. Methods: In this experiment, a new adequate ternary mixture liquid for preparation of BMF applied and suspended with a new scatter particle material, this scatter particle material called poly (4-methylstyrene), it used to be adequate with the mixture density and for saving neutrally buoyant. This BMF was prepared for use in the test objects or Doppler flow phantom. The poly (4 methylstyrene) particles were applied for suspension in a mixture liquid or fluid based on three items, which were distilled water, propylene glycol (PG), and polyethylene glycol (PEG) (200 Mw). The diameter of poly (4-methylstyrene) particles is 3-8 MUm, which determined by specific sieve in a unit of MUm, and the density is 1.040 g/ml. Results: Speed of sound, viscosity, density, Backscatter power and attenuation features of mixture fluid or liquid which used for preparing a BMF were measured, discussed, and agreed with draft International Electrotechnical Commission values. Conclusions: There are three various types of ternary items of mixture fluid (water, PG, and PEG [200 Mw]), and a new type of scatter particle material poly (4-methylstyrene) was utilized for preparing the BMF. The scatter particles and mixture fluid prepared and measured at a temperature that simulates the body temperature 37 degrees C. Moreover, one of the advantages of this new blood that is being cheaper than the commercially available BMF products because the PG and the polyethylene glycol (200 Mw) are much cheaper and more available than glycerol and the Dextran that used usually. In addition, new BMF needs less time for preparation compared to the commercial one. PMID- 30283200 TI - A Single Static Breast Model Education of Ultrasound Skill in Final Year Medical Students of Burapha University. AB - Background: Ultrasound (US) is widely used among physicians. There has been no standardized curriculum in US for undergraduate medical students. This study aimed to assess the US image acquisition skill of final year medical students after adding 2 weeks dedicated radiology rotation. Methods: At our institution, there are two hospital affiliations. Two-week radiology rotation was added for the final-year students of one affiliation. These students had a chance to do the US in real-life clinical settings proctored by radiologists. At the end of the academic year, US image acquisition skill was assessed by objective structured clinical examination (OSCE) in students from both affiliations. Results: From 48 final-year medical students, 28 students finished the 2 week radiology rotation. OSCE mean score of the students who received radiology rotation was significantly higher than other groups with a score of 65.5 compared to 53.3, respectively (P = 0.006). The student background characteristics had no relationship with the OSCE score (P = 0.565). Conclusion: Results showed that exposure through a dedicated radiology rotation in only 2 weeks is helpful to improve the US skill of the medical students regardless of their background performances. Exposure to live patients is essential for students' experiences. OSCE can be used as a standardized assessment tool. PMID- 30283201 TI - Ultrasound Evaluation of Soft-Tissue Foreign Bodies by US Army Medics. AB - Objective: The study's primary objective was to determine army medics' accuracy performing bedside ultrasound (US) to detect radiolucent foreign bodies (FBs) in a soft-tissue hand model. Secondary objectives included the assessment of US stand-off pad effects on soft-tissue FB detection rates and assess established FB detectable lower limit size of 2 mm. Methods: Prospective, single blinded, observational study of US-naive Army medics' abilities utilizing bedside US to detect wooden FBs in a chicken thigh model with or without an US stand-off pad. After a 2 h training period, medics' abilities to detect 1-3 mm FB utilizing a SonoSite(r) M-Turbo US and 13-6 MHz linear probe were assessed. Results: After a 2 h training period, 28 medics had a sensitivity and specificity of 73% and 78% detecting 1-3 mm FBs utilizing standard US equipment. The medics' sensitivity and specificity were both 78% in detecting radiolucent FBs 2 mm and larger without a stand-off pad. The sensitivity and specificity decreased to 48%, 62%, and 67% when utilizing a stand-off pad to detect 1, 2, and 3 mm soft-tissue FBs. Sub 2 mm detection rates decreased from 82% for 2 mm FB to 64% for 1 mm FBs without utilizing a stand-off pad. Conclusion: Army medics with minimal US experience successfully identified FBs embedded in hand models with accuracies similar to radiologists and emergency medicine physicians. However, radiolucent FB detection sensitivity and specificity decreased in US-naive Army medics utilizing stand-off pads. In addition, this study reconfirmed the lower limit of FB detection rates at 2 mm. These results support Army medics' utilization of US to evaluate for superficial radiolucent FBs of the hand. PMID- 30283202 TI - Large Multilocular Cystic Lesions in the Uterine Cervix: Differential Diagnosis and Significance. AB - Introduction: Cervical nabothian cysts are common in women of reproductive age. Although cysts are generally small and asymptomatic, large ones are extremely rare and may be misdiagnosed as malignancy. Case Study: We report a case of large multiple complex nabothian cyst, which was suspected as malignant one on imaging and examination. Pelvic examination and ultrasonography revealed ballooned cervix with multiple large complex nabothian follicles. There was an associated large adnexal mass with ascites. The patient was treated with total hysterectomy and omentectomy after aspiration of the fluid from the cervical cysts for debulking and limiting complications. Pathology revealed granulosa cell ovarian tumor, omental panniculitis, and cervical nabothian follicles. Conclusion: Large nabothian cysts should be kept in mind for differential diagnosis of cervical tumors. Ultrasonography is of value for the diagnosis of giant nabothian cysts and can aid in exclusion of malignancy. Differentiation between a malignant cystic lesion, such as an adenoma malignum, and a benign cystic lesion is crucial but difficult. Cervical nabothian follicles can be multiple and attain a large size up to 4 cm each. It is commonly benign but we should keep in mind the rare adenoma malignum on imaging and histopathology. PMID- 30283203 TI - Curvilinear Probe Endobronchial Ultrasound for Sampling of Parenchymal Lung Lesions. AB - Lung cancer is the leading cause of cancer related deaths in most countries. It can frequently be mimicked by other nonmalignant pulmonary lesions; and therefore, in the case of radiologically localized lesions a pathological diagnosis is preferable before proceeding to surgical resection. Curvilinear probe endobronchial ultrasound is widely used to sample lymph nodes, but in this case, we report that it can be beneficial for sampling parenchymal lung lesions not accessible at bronchoscopy in the absence of lymphadenopathy. PMID- 30283204 TI - Sonographic Diagnosis of a Colovesical Fistula Due to Sigmoid Colon Cancer. AB - Based on sonographic findings, colovesical fistula was diagnosed in a 71-year-old man with sigmoid colon cancer. Gray-scale sonography revealed an irregular thickening of the sigmoid colon wall abutting the urinary bladder which also showed thickening in the region of contact. Color Doppler sonography showed a twinkling artifact within the thickened bladder wall. Contrast-enhanced computed tomography scan showed luminal communication between the sigmoid colon and the bladder in the region of thickening. PMID- 30283205 TI - Color Doppler Ultrasonography to Evaluate Hypoechoic Areas in Pressure Ulcers: A Report of Two Cases. AB - Ultrasound (US) is frequently used for evaluating inflammation of subcutaneous tissue caused by pressure ulcers (PUs), but color Doppler mode (CDM) helps to better identify inflammatory edema in subcutaneous fat and necrotic tissue in PUs. We report two cases where inflammatory edema in subcutaneous fat and necrotic tissue in PUs are identified using small US equipment with CDM. Case 1 - An 82-year-old male presented with cerebral infarction and a Category III PU in the sacral region. B-mode gray-scale US imaging (B-mode imaging) revealed a thickened layer of subcutaneous fat with fat lobules and homogeneous cobblestone appearance with fluid accumulation within the echo-free space. CDM did not identify any color signal (CS) in hypoechoic areas. Case 2 - A 29-year-old female presented with cytopenia and decreased renal function with a Category IV PU with undermining in the coccyx region. B-mode imaging distinguished the necrotic tissue, indicating a diffuse hypoechoic area with no layers, unclear borders, and uneven gray level (cloud-like image) in the subcutaneous fat. Similar B-mode imaging findings were obtained in inflammatory edema with cobblestone appearance. CDM did not detect a CS in the hypoechoic areas but confirmed peripheral hypervascularity. CDM imaging identified inflammatory edema in the subcutaneous fat and necrotic tissue in PUs. Specifically, CDM may better evaluate early-stage PUs with necrotic tissue by distinguishing necrosis from intense inflammatory edema.

PMID- 30283213 TI - A mean score method for sensitivity analysis to departures from the missing at random assumption in randomised trials. AB - Most analyses of randomised trials with incomplete outcomes make untestable assumptions and should therefore be subjected to sensitivity analyses. However, methods for sensitivity analyses are not widely used. We propose a mean score approach for exploring global sensitivity to departures from missing at random or other assumptions about incomplete outcome data in a randomised trial. We assume a single outcome analysed under a generalised linear model. One or more sensitivity parameters, specified by the user, measure the degree of departure from missing at random in a pattern mixture model. Advantages of our method are that its sensitivity parameters are relatively easy to interpret and so can be elicited from subject matter experts; it is fast and non-stochastic; and its point estimate, standard error and confidence interval agree perfectly with standard methods when particular values of the sensitivity parameters make those standard methods appropriate. We illustrate the method using data from a mental health trial. PMID- 30283214 TI - Real-time Ultrasound Thermography and Thermometry. PMID- 30283212 TI - High Hydrostatic Pressure Induces a Lipid Phase Transition and Molecular Rearrangements in Low-Density Lipoprotein Nanoparticles. AB - Low-density lipoproteins (LDL) are natural lipid transporter in human plasma whose chemically modified forms contribute to the progression of atherosclerosis and cardiovascular diseases accounting for a vast majority of deaths in westernized civilizations. For the development of new treatment strategies, it is important to have a detailed picture of LDL nanoparticles on a molecular basis. Through the combination of X-ray and neutron small-angle scattering (SAS) techniques with high hydrostatic pressure (HHP) this study describes structural features of normolipidemic, triglyceride-rich and oxidized forms of LDL. Due to the different scattering contrasts for X-rays and neutrons, information on the effects of HHP on the internal structure determined by lipid rearrangements and changes in particle shape becomes accessible. Independent pressure and temperature variations provoke a phase transition in the lipid core domain. With increasing pressure an inter-related anisotropic deformation and flattening of the particle are induced. All LDL nanoparticles maintain their structural integrity even at 3000 bar and show a reversible response toward pressure variations. The present work depicts the complementarity of pressure and temperature as independent thermodynamic parameters and introduces HHP as a tool to study molecular assembling and interaction processes in distinct lipoprotein particles in a nondestructive manner. PMID- 30283215 TI - Crash Characteristics and Pattern of Motorcycle Related Facial Bone Fractures in a Sub-Urban Nigerian Teaching Hospital. AB - Context: Recent studies indicated that significant proportion of facial fractures attributed to road traffic mishaps in the middle- and low-income countries are caused by motorcycle (MC) crashes. However, there is limited information on crash characteristics of such injuries. This study was designed to examine the crash characteristics, pattern of fracture, and sociodemographics of patients with facial bone fractures due to MC crashes in our institution. Subjects and Methods: Data on patients' sociodemographics, pattern of presentation, type(s) of fracture, patient status, crash characteristics, level of consciousness, and treatment offered were collected and analyzed. Results: A total of 151 patients, aged 7-59 years were reviewed during the study period. A male preponderance was observed (M:F = 4:1) and the patients were predominantly motorcyclists (64.8%, n = 98). The most common mechanism of crash was collision with another MC (51.6%, n = 78). A total of 194 fractures were reviewed and the mandible (58.8%, n = 114) was more commonly affected than the midface (41.2%, n = 80). The predominant site on the mandible was the body (31.6%) while zygoma (32.5%) was the most affected part of the midface. Patient status was found to have a statistically significant relationship with loss of consciousness (P = 0.02). Eighty-two fracture sites (42.3%) were managed with open reduction and internal fixation. Conclusions: Facial bone fractures occur in a significant proportion of MC crashes and riders are predominantly affected. In addition, a larger proportion of commuters rarely wear crash helmet which could have offered protection. Continual advocacy on preventive measures and enforcement of road safety regulations is hereby advised. PMID- 30283216 TI - Histological Characteristics of Breast Lesions in Uyo, Nigeria. AB - Background: The breast is a common site for pathologies which predominantly involves the female breast. While benign diseases are more common, malignancies are of utmost concern for the patient, clinician, and the pathologist. Aim: The aim of this study is to audit the clinical and pathological features of patients with breast lumps in a tertiary center in Nigeria. Materials and Methods: This is a retrospective observational study of histologically diagnosed breast lumps over a period of 8 years. Results: Lumps were common in the 20-39 years age group (>50%), with a mean age of 34.95 years. Females accounted for 759 (98.1%) of cases. In 467 (60.4%) cases, the lumps measured >5 cm and only 175 (22.6%) cases presented to the surgeon within 12 weeks of noticing a breast lump. Ninety-one (11.8%) cases also presented with axillary lymph nodes, breast pain 79 (10.2%), peau d' orange 56 (7.2%), and ulceration 47 (6.1%). Benign breast disease (BBD) occurred in 401 (51.8%) cases and malignant breast diseases (MBD) occurred in 344 (44.3%) of cases. Conclusion: BBD and MBD are common among the young in Uyo. Lumps are the primary complaint and late presentation is the norm. PMID- 30283217 TI - Efficiency of Ultrasonography in Swellings of Orofacial Region. AB - Introduction: Ultrasonography (USG) is found to be important in identifying various soft-tissue pathologies in the orofacial region. Therefore, its features should be studied and documented in these lesions so that a more appropriate provisional diagnosis can be made. Aim: This study aims to study ultrasonographic features in various kinds of swellings in the orofacial region. Materials and Methods: The study grouped consists of 30 patients of both sexes (20 males and 10 females) with an age range of 15-70 years complaining of swellings in the orofacial region. All the patients in the study were explained the need of tests and subjected to clinical, ultrasonographic, and histopathologic examination. Sonosite Micromaxx sonography machine was used with a linear array transducer of 13-6 MHz frequencies. Ultrasonographic diagnosis is then correlated with clinical and histopathologic diagnosis. Chi-square test and contingency coefficient tests were used. Results: A significant association was observed between clinical and ultrasonographic diagnoses (contingency = 0.872, P < 0.05) and between ultrasonographic and histopathologic diagnoses (contingency = 0.904, P < 0.05). There was 100% congruency between clinical diagnosis and ultrasonographic diagnosis in all the cases except in cases of cysts, abscess, and sialadenitis. Reliability of USG was found to be 97% in diagnosing all the cases with respect to histopathological diagnosis, while it was 90% with respect to clinical diagnosis. Conclusion: USG was found to be a reliable diagnostic modality in the diagnosis of orofacial swellings. PMID- 30283218 TI - Radiographic Evaluation of Anterior Loop of Inferior Alveolar Nerve: A Cone-Beam Computer Tomography Study. AB - Background: A well awareness of the variation of inferior alveolar canal is mandatory to avoid iatrogenic complication. This study was conducted among 90 patients to determine variation in inferior alveolar nerve (IAN) loop through cone-beam computed tomography (CBCT) images. Materials and Methods: CBCT images of 90 patients were involved in this study. All images were studied by the expert radiologist to see Type I, Type II, and Type III pattern of IAN canal (IANC). Results were subjected to statistical analysis for correct inferences. Results: Forty males and 50 females were included in the study. The difference was statistically nonsignificant (P = 0.5). Type I pattern was seen in 26 patients, Type II in 19, and Type III in 45 patients. The difference was statistically significant (P < 0.05). The most prevalent pattern was Type III (males - 15 and females - 30), followed by Type I (males - 14 and females - 12) and Type II (males - 11 and females - 8). There was statistical significance difference between males and females in Type II (P < 0.05). Conclusion: The anterior loop of IAC is quite common and IANC may show variation in structure. The most common pattern recorded was Type III. CBCT is very useful in the detection of IANC. PMID- 30283219 TI - A Clinical Study on Comparative Evaluation of the Effectiveness of Carbamazepine and Combination of Carbamazepine with Baclofen or Capsaicin in the Management of Trigeminal Neuralgia. AB - Background: Trigeminal neuralgia (TN) is characterized by recurrent attacks of lancinating pain in the trigeminal nerve distribution. Various medicinal and surgical procedures have been utilized for the treatment of TN. Over the time, several drugs other than carbamazepine have been used but none of them have shown satisfying results. Objective: The objective of the study is to evaluate the effectiveness of carbamazepine and combination of carbamazepine with baclofen or capsaicin in the management of TN. Materials and Methods: A total of 45 patients diagnosed with TN were randomly divided into three groups. The patients were prescribed carbamazepine in Group 1, carbamazepine and baclofen in Group 2, and carbamazepine and capsaicin in Group 3. All the patients were followed on the 7th day, 15th day, and 1-month period to evaluate the response to the drugs. Data were subjected to statistics. Results: The results are composed of a total of 45 patients (15 in each group). The mean visual analogue scale scores were calculated for each group at day 0, 7th day, 15th day, and 30 days, and it was found that there was statistically significant reduction of pain (P < 0.001) in all the three groups at different intervals. At day 7, comparative percentage reduction of pain in both groups was not statistically significant. At 15-days and 30 days, percentage change in pain reduction in Group 1 was 42.3% and 48.0% respectively and in Group 2 it was found to be 60.3% and 83.4%, respectively. The reduction in pain percentage was found to be statistically significant. Similarly, Group 1 was compared to Group 3, significant reduction of pain was found for carbamazepine-capsaicin combination at 30-day interval but the comparative reduction of pain at 7th day and 15th day was not statistically significant. Conclusion: Carbamazepine in combination with baclofen is more efficient and effective in reducing pain in TN patients, followed by carbamazepine-capsaicin combination compared to carbamazepine alone. PMID- 30283220 TI - Evaluation of Immunohistochemical Profile of Breast Cancer for Prognostics and Therapeutic Use. AB - Introduction: Breast cancer is leading cancer in women, and the incidence of breast cancer in India is on the rise. The most common histologic type of breast cancer is infiltrating ductal carcinoma. Prognostic and predictive factors are used in the management of breast cancer. Estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2/neu) are immunohistochemical markers of prognosis as well as predictors of response to therapy. Aims and Objectives: The study was conducted to evaluate ER, PR, and HER2/neu expressions in invasive ductal carcinomas of the breast by immunohistochemistry, to explore the correlation of these markers to each other and to various clinicopathological parameters: age of the patient, histological grade, tumor size, and lymph node metastasis. Materials and Methods: This prospective study was conducted on 100 cases of infiltrating ductal carcinoma. Slides were prepared from blocks containing cancer tissue, and immunohistochemical staining was done for ER, PR, and HER2/neu expressions. Interpretation of expressions was done using Allred scoring system for ER/PR and the American Society of Clinical Oncology/College of American Pathologists guidelines for HER2/neu. Statistical analysis was performed to determine the statistical significance by applying Chi-square test. Results: Majority of tumors were ER and PR positive and HER2/neu negative. ER and PR correlated significantly with age, tumor size, and tumor grade; whereas, HER2/neu correlated significantly with tumor size only. No association was seen with axillary lymph node metastasis. ER and PR expression correlated with each other, but none correlated with HER2/neu. Conclusions: As the majority of the tumors are ER, PR positive and since ER and PR correlate with each other as well as with age, tumor size, and grade. Therefore, routine assessment of hormone receptors is recommended for prognostic and therapeutic information in breast cancer cases. PMID- 30283221 TI - Tumor Necrosis Factor-Alpha and Interleukin-1 Alpha as Predictors of Survival in Peritonitis: A Pilot Study. AB - Context: Peritonitis induces an inflammatory response characterized by the elevation of various cytokine levels. Included in this cascade of cytokines are tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 alpha (IL-1alpha). The outcome of patient care may be associated with the pattern of elaboration of these cytokines. Aim: The aim of this study was to describe the pattern of cytokine response (TNF-alpha and IL-1alpha) in the course of peritonitis and evaluate them as predictors of mortality in peritonitis. Setting and Design: This was a prospective study conducted in the Division of Gastrointestinal Surgery, University College Hospital, Ibadan. Methods: Consenting patients with clinical diagnosis of generalized peritonitis over a 6-month period (July to December 2015) were recruited. The serum samples of these patients were obtained at presentation, immediately after surgery, and 24 h and 48 h after surgery with a follow-up period of 30 days. Results: Twenty-six samples out of thirty could be analyzed. Serum TNF-alpha and IL-1alpha levels were both elevated at presentation in all patients. However, the patterns of change after intervention varied between the survivors and nonsurvivors. Conclusion: Peritonitis triggers a simultaneous increase in serum levels of TNFalpha and IL-1alpha. Lower serum level of TNF-alpha is associated with survival, while on the contrary, higher level of IL-1alpha is associated with survival. PMID- 30283223 TI - Emergency Ileo-cecal Anastomosis with Inclusion of Appendicular Stump in Terminal Ileal Pathology: A Newer Approach. AB - Background: In emergency settings, several surgical procedures are described while dealing with pathology of terminal ileal lying within 15 cm of the ileocecal valve, but there is still confusion and controversy over the optimal surgical treatment. Methods: A nonrandomized study of 210 patients with near terminal ileal pathology (within 15 cm) was carried out over a period of 10 years. The study included 112 cases in which an ileocecal anastomosis with inclusion of appendicular stump was used in terminal ileal pathologies, and in rest 98 cases, other surgical procedures were used. The outcomes were measured in relation to postoperative complications and mortality. Results: Postoperative complications encountered in emergency ileocecal anastomosis with the inclusion of appendicular stump were wound infection in 31 patients (34.72%), respiratory complications in 10 patients (11.2%), septicemia in 6 patients (6.72.%), and anastomotic leak in one patient (1.12%). Conclusion: The technique of ileocecal single-layer anastomosis with the inclusion of appendicular stump was found to be very effective in dealing this common problem and had less morbidity and mortality. PMID- 30283222 TI - Use of the World Health Organization Surgical Safety Checklist by Nigerian anesthetists. AB - Background: Surgery and anesthesia are essential parts of global healthcare. Surgical intervention has been largely beneficial but remains associated with significant morbidity and mortality. The increasing complexity of surgical interventions has made providers more prone to avoidable errors. The World Health Organization Surgical Safety Checklist (WHO SSC) was disseminated worldwide with the aim of reducing perioperative morbidity and mortality. Objective: There is a paucity of data to assess awareness and use of WHO SSC in low- and middle-income countries. The aim of this study is to evaluate the knowledge and use of WHO SSC by Nigerian anesthetists. Methodology: A structured self-reporting questionnaire was distributed to Nigerian physician anesthetists. One hundred and twenty-two questionnaires were distributed with 102 completed reflecting a response rate of 83.6%. Results: Awareness of the WHO SSC was reported by 93.1% of the respondents. Routine use of the checklist was reported by 62.7% of the respondents mostly in the teaching hospitals compared with the general hospitals and comprehensive health centers (86.2%, 23.3% and 14.3%, P = 0.0001). The respondents who had a perception that WHO SSC does not prevent errors were the least likely to use it (odds ratio: 0.08, P = 0.0117). Conclusion: This study identified a high level of awareness and use of the WHO SSC by physician anesthetists in Nigeria. However, its use is mostly use of The WHO SSC list by Nigerian anesthetists in teaching hospitals. PMID- 30283224 TI - Role of Hunger Hormone "Ghrelin" in Long-Term Weight Loss Following Laparoscopic Sleeve Gastrectomy. AB - Introduction: Laparoscopic sleeve gastrectomy (LSG) has become a popular weight loss technique in morbidly obese patients. The aim of our study was to evaluate the changes in plasma ghrelin levels in relation to weight loss following LSG and to study the efficacy of LSG in terms of long-term glycemic control and resolution of diabetes. Methodology: The study was conducted on 70 morbidly obese patients (body mass index [BMI] >40 kg/m2) or severely obese patients (BMI >35 kg/m2) with comorbidities who underwent LSG in Dayanand Medical College and Hospital, Ludhiana, India. Ghrelin levels were measured preoperatively and postoperatively at 1 week, 3 months, and 6 months along with measurements of various weight loss parameters and glycosylated hemoglobin. Results: A significant decrease in plasma ghrelin levels was observed in relation to the mean weight and percentage excess weight loss at 3 months postoperatively. However, at 6 months, fall in ghrelin reached a plateau phase while weight loss was still sustained and significant. There was a significant fall in glycosylated hemoglobin levels with patients achieving good control/resolution of diabetes Type II. Conclusion: LSG is an effective weight loss surgery and brings about excellent weight loss in morbidly obese individuals in addition to achievement of good glycemic control in diabetic individuals. Serum levels of ghrelin fall significantly after sleeve gastrectomy. However, long term implications of ghrelin induced weight loss cannot be elucidated. PMID- 30283225 TI - Maxillectomy and Quality of Life: Experience from a Nigerian Tertiary Institution. AB - Introduction: Maxillectomy is a surgical procedure for managing tumors affecting the maxilla; the goal of maxillectomy however should not be limited to tumor extirpation but should include restoration of oronasal function and facial contours, as failure to do these may give rise to psychosocial and functional challenges. This study aimed to appraise the pattern of maxillectomies, challenges of management, and quality of life (QOL) of a proportion of the study population. Materials and Methods: This was a cross-sectional study carried out at the Department of Oral and Maxillofacial Surgery, University College Hospital, Ibadan. Patients' case files from year 2000 to 2016 were retrieved and reviewed. Data extracted for analysis included age, gender, site of lesion, and histologic diagnosis; lesions were grouped as benign or malignant. Contacts were made with patients or their next of kin for a clinic review appointment where QOL was assessed with the University of Washington Quality of Life version 4 Questionnaire. Data were analyzed and result presented as means and frequencies. Results: Out of the 78 cases of maxillectomy recorded in the department within the study period, records were available and adequate in 67 cases. There were 37 (55.2%) females with a mean age of 35.88 +/- 14.9 years. Swelling was the most common reason for presentation (63, 94%). The mean period between onset of disease and presentation for treatment was 3.66 +/- 3.35 years. Distribution of lesions was benign 35 (52.2%) and malignant 32 (47.8%). Hemi-maxillectomy was the commonest surgical procedure (23, 34.8%). While majority had some prosthetic rehabilitation, 31 participants (48.5%) obtained no prosthesis. Eight participants gave scores of >=75% when comparing their present health-related QOL (HR-QOL) with a month before surgery; the overall QOL was >=60%. However, HR-QOL and overall QOL in the last 7 days before assessment were rated as good in 55.6% and 66.7%, respectively. Chewing was the most important domain to participants. Conclusion: The pattern of presentation and indications for maxillectomy in this series are similar to that from previous studies. The uptake of prosthetic rehabilitation was low and overall QOL was rated as fair. QOL should be considered as part of treatment outcome measure for maxillectomy. PMID- 30283226 TI - Mixed Adenoneuroendocrine Carcinoma of the Esophagus: A Case Report and Review of the Literature. AB - The most frequent presentation of esophageal cancer is adenocarcinoma and squamous cell carcinoma. In recent years, the latter has decreased its incidence increasing the adenocarcinoma. Currently, another type of tumor with a much lower incidence has been described, which has a neuroendocrine component along with another exocrine glandular component and has been classified since 2010 as mixed adenoneuroendocrine carcinoma (MANEC). We present the case of a 68-year-old male with a history of dyspepsia and epigastric pain who after performing a gastroscopy, was diagnosed with a malignant neoplasm of the esophagus. The patient underwent a total esophagectomy with reconstruction by tubular gastroplasty with cervical anastomosis. The final result of the piece after immunohistochemistry revealed that the tumor was composed of one component of adenocarcinoma in 60% together with another component compatible with neuroendocrine in 40%. With these findings and according to the World Health Organization classification of 2010 was diagnosed as esophageal MANEC. MANECs are rare tumors, described in other locations of the digestive tract, the esophagus being an infrequent location. Its preoperative diagnosis is difficult, and it is not until the final analysis of the complete piece by means of specific immunohistochemical techniques when its diagnosis can be established. Its treatment is fundamentally surgical, whereas the adjuvant therapeutic schemes with chemotherapy are not well defined at present because of their low incidence. PMID- 30283227 TI - Secretory Carcinoma of the Breast in a 20-year-old Male: Case Report and Review of Literature. AB - Secretory breast carcinoma (SBC) is a very rare low-grade subtype of breast carcinoma. It was initially termed "juvenile breast cancer," but it is now known to occur in adults of both sexes, and only few male cases have been reported in the literature. SBC is of importance because of its unique morphology and excellent prognosis. We report here a case in a 20-year-old male presenting with right pedunculated and ulcerated breast mass with associated contact bleeding. Histopathology was performed and it revealed a secretory carcinoma. This tumor is morphologically characterized by the presence of abundant eosinophilic secretions in intracellular vacuoles and intercellular spaces. The objective of this article is to review the epidemiological and clinical aspect of secretory carcinoma from a case report and literature review. PMID- 30283228 TI - Unsuspected Skin Metastasis of Adenocarcinoma of the Prostate in a Patient on Goserelin (Zoladex). AB - Prostate cancer remains the most common noncutaneous cancer in men, especially in this era of prostate-specific antigen assay. Prostate cancer metastases have been known to commonly affect the lymphatics, bones, and lungs. Prostate cancer metastasis to the skin is very rare (<1%) and often signifies a terminal disease. Involvement of the skin has been thought to be through lymphatic spread by embolization or permeation, hematogenous spread, and implantation during surgery (port site in radical prostatectomy). We report a 74-year-old man on management for advanced prostate cancer with subcutaneous goserelin (Zoladex) but developed skin metastasis in the course of treatment. The skin metastasis in our patient, however, was initially localized to the site of the regions of subcutaneous goserelin injection that we imagined if there is a link between the two. We reviewed the literature and currently found no connection. Is there truly a link? PMID- 30283229 TI - Postcraniectomy Cranioplasty Using Autologous Split Calvarial Graft. PMID- 30283230 TI - Using Semantic Web Technologies to Enable Cancer Genomics Discovery at Petabyte Scale. AB - Increased efforts in cancer genomics research and bioinformatics are producing tremendous amounts of data. These data are diverse in origin, format, and content. As the amount of available sequencing data increase, technologies that make them discoverable and usable are critically needed. In response, we have developed a Semantic Web-based Data Browser, a tool allowing users to visually build and execute ontology-driven queries. This approach simplifies access to available data and improves the process of using them in analyses on the Seven Bridges Cancer Genomics Cloud (CGC; www.cancergenomicscloud.org). The Data Browser makes large data sets easily explorable and simplifies the retrieval of specific data of interest. Although initially implemented on top of The Cancer Genome Atlas (TCGA) data set, the Data Browser's architecture allows for seamless integration of other data sets. By deploying it on the CGC, we have enabled remote researchers to access data and perform collaborative investigations. PMID- 30283231 TI - Habitat requirements of endangered species in a former coppice of high conservation value. AB - Transformation of coppices to high forests has caused fundamental changes in site conditions and a decline of many species across Central Europe. Nevertheless, some formerly coppiced forests still harbour a number of the declining species and have become biodiversity hotspots in the changing landscape. We focused on the best preserved remnant of formerly grazed and coppiced subcontinental oak forest in the Czech Republic - Dubrava forest near Hodonin. To improve our understanding of the ecology of the declining species, we studied local habitat requirements of vascular plants most endangered at the national level. We recorded vegetation composition and sampled important site variables in plots with the largest populations of endangered species and in additional plots placed randomly across all major forest habitats. We demonstrated that sites with endangered species have a highly uneven distribution in ecological space and their species composition is often similar to open-canopy oak forests. Within this habitat, the endangered species are concentrated in places with a high light availability and high soil pH. Light-demanding species characteristic of subcontinental oak forests are the best indicators of these sites, while broadly distributed shade-tolerant and nutrient-demanding species avoid them. These results support the view that the occurrence of many endangered species in Dubrava forest is a legacy of the long history of traditional management that kept the canopies open. The light-demanding species are now threatened by ongoing successional changes. Therefore, active conservation measures are recommended, including opening up the canopies, early thinning of young stands, control of expansive and invasive species and understorey grazing or mowing. PMID- 30283232 TI - New species of parasitic nasal mites infesting birds in Manitoba, Canada (Mesostigmata, Rhinonyssidae). AB - Mites (Acari, Acariformes, Parasitiformes) are one of the most diverse and abundant groups of arthropods associated with birds. Several families of mites have colonised the respiratory tract of birds, the Rhinonyssidae (Mesostigmata) being the most diverse. There are 66 species of rhinonyssids (59 named, seven undescribed species) reported from Canadian birds. Two new species of rhinonyssids were discovered while surveying nasal mites from birds in Manitoba, Canada, and are herein described as Sternostomagallowayi sp. n. from the horned lark (Eremophilaalpestris), and Vitznyssuserici sp. n. from the common nighthawk (Chordeilesminor). PMID- 30283233 TI - Cryptic diversity in Andrognathuscorticarius Cope, 1869 and description of a new Andrognathus species from New Mexico (Diplopoda, Platydesmida, Andrognathidae). AB - Andrognathus is a genus of small, thin-bodied millipedes found in deciduous forests of North America. Poorly understood, these organisms inhabit decaying wood and have morphologically conserved and difficult-to-identify sexual characters that have limited study historically. Recent use of scanning electron microscopy has uncovered variation in male genitalia that was previously unknown in the genus. The distribution of Andrognathus and the extent of this variability across the continent, however, were undocumented, and a wealth of natural history collections remained uncatalogued. Here a new species of Andrognathus is described from New Mexico, Andrognathusgrubbsi sp. n., natural history collections are utilized to create a comprehensive map of the genus, and a neotype established for the type species, Andrognathuscorticarius Cope, 1869. Analysis of the cytochrome oxidase I gene (COI) for A.corticarius was completed for the type series and individuals across the species distribution, but little variation was found. Andrognathusgrubbsi sp. n. joins A.corticarius and A.hoffmani Shear & Marek, 2009 as the only members of the genus. PMID- 30283234 TI - Two new species of the millipede genus Metonomastus Attems, 1937 from the Balkan Peninsula (Diplopoda, Polydesmida, Paradoxosomatidae).

PMID- 30283237 TI - A new genus and species of clingfish from the Rangitahua Kermadec Islands of New Zealand (Teleostei, Gobiesocidae). AB - Flexorincus, new genus and species, is described from 15 specimens (14.0-27.2 mm SL) collected from shallow (0-9 meters) intertidal and sub-tidal waters of the Rangitahua Kermadec Islands, New Zealand. The new taxon is distinguished from all other members of the Gobiesocidae by a combination of characters, including a heterodont dentition comprising both conical and distinct incisiviform teeth that are laterally compressed with a strongly recurved cusp, an oval-shaped opening between premaxillae, a double adhesive disc with a well-developed articulation between basipterygia and ventral postcleithra, and many reductions in the cephalic lateral line canal system. The new taxon is tentatively placed within the subfamily Diplocrepinae but shares a number of characteristics of the oral jaws and the adhesive disc skeleton with certain members of the Aspasminae and Diademichthyinae. PMID- 30283238 TI - Tosanoidesaphrodite, a new species from mesophotic coral ecosystems of St. Paul's Rocks, Mid Atlantic Ridge (Perciformes, Serranidae, Anthiadinae). AB - During a recent expedition to St. Paul's Rocks, Atlantic Ocean, a distinctive and previously unknown species of Anthiadinae was collected at a depth of 120 m. A genetic analysis indicated the undescribed species is a member of the genus Tosanoides, which was only known to occur in the Pacific Ocean. This new taxon is distinguishable from all other Tosanoides species by the following combination of characters: soft dorsal fin rays 15-16; anal fin rays 9; ventral scale rows 9-10; last dorsal spine the longest (instead first through fourth). Here Tosanoidesaphrodite sp. n. is described and illustrated, only known from St. Paul's Rocks. PMID- 30283239 TI - What is the Potential for Community Currencies to Deliver Positive Public Health Outcomes? Case Study of Time Credits in Wisbech, Cambridgeshire, UK. AB - There is evidence that increased levels of community engagement and social participation can improve population health. Community currencies such as Time Credits are one way to support and encourage people to be more involved in their local community. As a result, they have attracted investment by local governments in the UK, with the hope of finding new ways to work with deprived communities, improve individual outcomes that lead to better health, and reduce the use of public services at a time of financial austerity. The aim of this research was to evaluate the health related outcomes of volunteering through Time Credits in Wisbech, Cambridgeshire. The conceptual model developed during the research shows how Time Credits were expected to influence some of the social determinants of health and, by doing so, enhance health outcomes and reduce health inequalities. This in depth empirical study shows the potential of such activity to support pathways to better health, but equally demonstrates the challenges in quantifying such outcomes and in evidencing any reduction in the use of public services as a result. PMID- 30283240 TI - 2D:4D digit ratio and religiosity in university student and general population samples. AB - The ratio of index to ring finger length (2D:4D) is used as a proxy for prenatal sex hormone exposure. It has been hypothesised to correlate with religiosity, though no published research has explored this possibility. Here, we initially examined 2D:4D in relation to self-reported religious affiliation and questionnaire measures of general religiosity, spirituality, religious fundamentalism, and religious commitment in male (N = 106) and female (N = 105) university students (Study 1). Although no significant correlations were observed between 2D:4D and the questionnaire measures, females who affiliated with organised religions had higher digit ratios compared to agnostic or atheist females. Study 2 attempted to replicate these findings in an adult general population sample (N = 172 males, N = 257 females), but did not observe significant effects in either sex. Overall, these findings suggest that high 2D:4D may be relatively-specifically associated with religious affiliation in young, highly-educated, females.

PMID- 30283242 TI - Prevention of Diabetes: Countless Opportunities and Clear Challenges. AB - Prevention of diabetes poses significant challenges; especially when applied as public health intervention. While several trials, most importantly Diabetes Prevention Program, show that intensive lifestyle modification leading to weight loss is the most important intervention, many individuals and some populations may show resistance to these interventions. Roadblocks to lifestyle intervention alone or in combination include: age, some ethnic groups (e.g., south Asians), genetic make-up, and some characteristics of body phenotype. Recent data show that non-alcoholic fatty liver disease along with insulin resistance may constitute 'metabolically unhealthy phenotype'. These subgroups would need more intensive interventions to convert prediabetes to normal glucose regulation. Whether 'fatty pancreas' and sarcopenia, latter more often seen in Asian Indians and with advancing age, are other phenotypes requiring intensive and different interventions (e.g., more resistance exercise in latter) remains to be researched. Further, variations in dietary quality (Mediterranean diet enriched with extra virgin olive oil, high-protein diets) without changing much of calories, provide attractive options for intervention. Many of such innovations require more research. Translation of lessons from diabetes prevention studies to general population is daunting but possible. However, such community-based interventions need substantial human and material resources, which pose hurdles in underserved populations and developing countries. In such situations, low-cost modalities, for example, use of trained community educators and digital and social media, constitute attractive approaches. PMID- 30283243 TI - Lifestyle and Pharmacotherapy for Weight Loss in Preventing or Delaying Diabetes. AB - Preventing or delaying the conversion of prediabetes to overt diabetes can reduce mortality and morbidity rates, improve health-related quality of life, and reduce other comorbid complications associated with diabetes. Studies have shown that a modest weight loss is one strategy for preventing or delaying diabetes diagnosis. First-line therapy in preventing progression of prediabetes to overt diabetes is weight loss through lifestyle modifications; however, pharmacotherapy for weight loss may be initiated if lifestyle alone is ineffective. The purpose of this article is to describe the pharmacotherapeuptic options for weight loss that can be used in conjunction with lifestyle in the prevention or delay of diabetes in patients with prediabetes. PMID- 30283244 TI - Lifestyle Choices Can Augment Female Sexual Well-Being. AB - Female sexual wellbeing is complex and it's an important part of a comprehensive approach to women's health. Unfortunately, this aspect of health often is not discussed during medical appointments which can be isolating for female patients. Low libido is the most common female sexual dysfunction. There are multiple causes of low libido that may be physical, cultural, emotional, medical psychological or due to her relationship with her partner. A healthy lifestyle is one way to help women overcome low libido and a few examples include exercise, mindfulness and yoga. Ultimately, these lifestyle approaches can enhance sexual satisfaction. PMID- 30283245 TI - Uncovering the Truth. AB - Finding the truth is important. In the field of lifestyle medicine the randomized controlled trial has significant limitations. Physicians and patients need to know the truth about the healthy lifestyle changes and their ability to prevent and reverse disease. To meet this challenge, the American College of Lifestyle Medicine has established a committee of experts (HEaLM), under the leadership of David Katz to create a level of evidence construct for ranking lifestyle medicine evidence that includes evidence from basic science and epidemiologic trials. This tool will be used by the new Expert Lifestyle Medicine Panel to create guidelines and standards of practice. PMID- 30283246 TI - Nutritional Assessment and Intervention to Prevent and Treat Malnutrition for Fall Risk Reduction in Elderly Populations. AB - The aging US population is increasing, and it is estimated that adults older than 65 years will make up 20% of the population by 2029 and the proportion of individuals in the United States older than 65 years will outnumber individuals younger than 18 years. In older adults, accidental falls are the leading cause of fatal and nonfatal injuries. Prevalence of chronic conditions such as sarcopenia and frailty contribute to the increased risk for fall observed in this population. Nutritional status in elderly individuals is a key predictor of both frailty and sarcopenia, thus ensuring adequacy in these populations has the potential for preventing falls. Poor nutritional status is associated with the onset of frailty. Nutrition screening, assessment and interventions can be targeted at this age group to overcome treat and prevent malnutrition to minimize fall risk. PMID- 30283247 TI - Advocating for Behavior Change With Education. AB - Education is ubiquitous with clinical care. However, not all education supports behavioral change. Education is a broad term that encompasses the process of obtaining general knowledge, personal awareness, and skills training. Although not sufficient, education is a necessary component for behavior change. This article outlines the role of education in behavior change and offers practical suggestions for how clinicians can provide education to their patients to help them change behavior. PMID- 30283248 TI - Prevention of Pediatric Pharmaceutical Poisonings. AB - Pediatric poisoning remains a common, preventable childhood injury and incidence is on the rise. Child-resistant packaging has been shown to prevent pharmaceutical poisoning, but must be applied and used appropriately to be effective. Prescription drug use among adults is also increasing and may be contributing to the problem through a greater number of medications in the child's environment. Drug take back programs are designed to reduce the number of unused medications in the home. These programs are expanding and health care providers should be aware of and encourage safe drug disposal practices. PMID- 30283249 TI - In Search of a Good Night's Sleep: Hormones, Mind, Movement, and Breath. AB - Sleep disturbances are common in postmenopausal women and contribute to increased morbidity and mortality. Sleep apnea may be underdiagnosed in women, and other conditions such as insomnia and restless legs may coexist with sleep apnea. This case illustrates the complex interplay of anatomical, hormonal, metabolic and psychological factors that can interfere with restorative sleep, and the importance of both diagnostic testing and clinical history in identifying which combination of therapies will be most beneficial in improving sleep quality and quantity. PMID- 30283250 TI - Informed Consent: Is It Accompanied by Full Disclosure? AB - Informed consent assumes full disclosure has been discussed in its entirety. However, is full disclosure ever really achieved? This column discusses how lifestyle medicine, both philosophically and ethically, must be a standard component of informed consent. Yet despite unequivocal evidence regarding the efficacy of lifestyle medicine, few physicians even consider lifestyle medicine as a viable option in the informed consent process. Reasons for the lack of lifestyle medicine considerations are postulated and a potential solution through education of trainees is suggested. How one medical school is addressing the need for lifestyle medicine education through several initiatives is discussed. Last, we expect that trainees educated in lifestyle medicine will push the momentum forward toward the "tipping point" where lifestyle medicine will be a viable option in the informed consent process-only then will full disclosure truly be achieved. PMID- 30283251 TI - Awareness of Cancer Risk: Variation in Measurement Approaches. AB - Cancer is a major cause of morbidity and mortality. Diet, nutrition, physical inactivity, and obesity have been identified as important contributors to the increasing cancer incidence worldwide. To effectively plan interventions to reduce cancer incidence and to influence the public's decisions regarding health behaviors, it is important for professionals to have an understanding of the ways in which people understand risk with regard to development of cancer. Selecting an appropriate method to evaluate awareness of cancer risk is an important consideration. Quantitative approaches such as surveys may be used to investigate awareness of risk, and recall of risk factors as well as recognition of such factors may form part of such assessments. Such quantitative methods may be used to evaluate risk in different demographic groups, as well as to examine the link between risk factors and behavior. Qualitative approaches include in-depth interviews, focus groups, and open-ended survey items and may be used to explain findings derived using quantitative methods. Mixed methods approaches may also be employed, involving use of a survey as well as interviews or focus groups to gather in-depth information. Assessment of awareness of cancer risk using an appropriate method has important implications for educators, as professionals must evaluate understanding of risk factors and tailor messages accordingly for educational programs. Ongoing evaluation of awareness is a key part of determining the effectiveness of education initiatives and identifying new and emerging issues. PMID- 30283252 TI - Healthy Living After Cancer Treatment: Considerations for Clinical and Community Practice. AB - As the number of US cancer survivors now reaches almost 16 million, understanding how to care for survivors after cancer treatment has demanded national attention. Increasingly, compelling benefits of lifestyle behaviors for cancer prevention and control have been demonstrated. In particular, physical activity is recommended as a central component of healthy living after cancer treatment. However, survivors struggle to achieve recommended physical activity and other behaviors for reasons that are still not well understood. Further, as greater than 60% of cancer survivors are older than 65 years, there is a unique opportunity to increase engagement of older adults in health programs and clinical trials. This article considers evidence from two reviews: a review on epidemiology studies of lifestyle and cancer and a review on different behavioral intervention strategies to achieve positive behavioral changes in cancer survivors. Both reviews offer important evidence on the role of lifestyle in life after cancer treatment. However, more investigation is needed on the practice of lifestyle medicine for cancer survivors, including ways to extend the reach of health promotion beyond cancer clinics, to primary care and community settings. PMID- 30283253 TI - Integrating Physical Activity Into Clinical Cancer Care. AB - Physical activity is an important target for improving health and well-being among cancer survivors. Cancer clinicians are uniquely positioned to promote physical activity among survivors through follow-up visits for treatment planning and surveillance. Providers should prioritize assessment of guideline-concordant physical activity and facilitate achievement of physical activity guidelines through exercise prescription, goal setting, addressing barriers, and capitalizing on support systems.

AB - Contemporary hormonal contraception formulations contain lower doses of estrogen, have new synthetic progestin components, and provide novel methods of delivery that have not been studied extensively in relation to breast cancer risk. Given that hormonal contraception is the leading method of birth control in the United States, it is important to reevaluate risk using current formulations. Recent studies including contemporary hormonal contraception formulations will be described. PMID- 30283255 TI - Lifestyle Medicine Inpatient Consultation Services at Loma Linda University Health: A Novel Approach in a Tertiary Care Center. AB - As a nation facing primary care provider shortages, an expanding chronic disease burden, and rising health care costs, lifestyle medicine interventions have become critical for patient care and management. The current fee-for-service health care system in the United States is designed for delivering acute care but has made it challenging to deliver and be reimbursed sufficiently for lifestyle interventions that can help prevent and treat chronic disease. Loma Linda University Health began to address these concerns through the creation of an inpatient consultation service for the neurology rehabilitation stroke team. Initiation of the consultation service took 2 years of planning, testing, and resource development. Currently, the consultation service operates one half-day per week in the rehabilitation hospital utilizing 1 attending physician and 2 residents. Visiting residents and medical students are also permitted to rotate with the new service. In coordination with billing experts, a standard number of 21.2 to 25.4 RVUs (relative value units) has been established for the half-day service. As the service continues to expand, future considerations include adding consultation availability to other departments and increasing the consultation workforce.

PMID- 30283264 TI - Common Misconceptions in the Nutritional Management of Athletes. AB - Athletes today face a multitude of competing voices with health claims and products to enhance performance. This has led to both confusion and misconceptions about healthy dietary practices for athletes. Research has demonstrated that athletes do not understand the recommended nutritional requirements necessary for health. Further, improper study methods and research design can create and propagate misconceptions about how athletes view their own health and personal sacrifices. These misconceptions not only influence attitudes and recommendations by healthcare providers and coaches but can also affect legislation. Healthcare providers, coaches and trainers have the opportunity to positively influence healthy nutritional lifestyles in athletes. Research has demonstrated that the balance of expert power and referent power have been shown to emphasize personal empowerment and long term change. PMID- 30283265 TI - Clinical Lifestyle Medicine Strategies for Preventing and Reversing Memory Loss in Alzheimer's. AB - Alzheimer's disease (AD) is the most common form of dementia and currently affects over 5 million Americans and 30 million individuals worldwide. Unfortunately, the current approach to treating AD provides nothing more than a marginal, unsustained, symptomatic effect, with little or no effect on disease progression itself. To attain effective improvements in AD, one must determine risk factors, address the underlying causes, and focus on a combination of functional and lifestyle medicine strategies that provide a comprehensive, programmatic, and network-based approach that is sufficient to achieve epigenetic transformation and neurologic healing through its multiple and necessary synergistic components. Rather than normalizing metabolic parameters, the focus is on optimization of each metabolic parameter. Papers published by research neurologist, Dr Dale Bredesen have documented that symptoms of mild cognitive impairment and early AD may often be reversed within 6 months after initiating a comprehensive, functional and lifestyle medicine-focused program. The purpose of this article are as follows: 1. Shed light on a promising clinical protocol that focuses on a comprehensive functional and lifestyle medicine approach to treating mild cognitive decline and Alzheimer's disease; 2. Identify the Bredesen Protocol testing, diagnostic and treatment guidelines; 3. Review several case studies and discuss the promising results of the program. Although published case studies such as those reported here are relatively few, clinicians applying these comprehensive strategies have reason to expect improvement in their patients. Lifestyle medicine can be a source of greatly needed hope for those suffering with cognitive decline. PMID- 30283267 TI - The Lifestyle Medicine Outpatient Clinic at Loma Linda University Health. AB - Medical management of chronic health concerns relies heavily on behavioral change, most specifically medication adherence. Yet approximately 50% of patients with chronic illnesses are not thought to take their medications as prescribed. Moreover, it is recognized that lifestyle and behavioral changes can reduce the need for medication. It is well documented that patient outcomes and their success in achieving behavioral change is improved with engagement and support from a medical care team. As the inpatient lifestyle medicine service was being conceptualized at Loma Linda University Health (LLUH), it became apparent that an outpatient service would be necessary for follow-up care of the patients and support the lifestyle medicine treatments initiated in the hospital. Additionally, an outpatient clinic would be available to the patient population at Loma Linda and potentially prevent hospitalizations, morbidity, and mortality with proactive lifestyle medicine treatment. The initial outpatient clinic opened in February 2017 and was soon expanded to meet patient demand. Currently, the LLUH Lifestyle Medicine Outpatient Clinic is available 5 days a week, utilizing 5 physicians.

PMID- 30283270 TI - The Impact of Using Genotyped Reagent Red Blood Cells in Antibody Identification. AB - Background: The detection and identification of antibodies to red blood cell (RBC) antigens is one of the most important and challenging issues in transfusion medicine. Up to date there are 354 RBC antigens recognized by the International Society of Blood Transfusion (ISBT). The reagent RBCs used in commercial antibody screening and identification panels however are usually serologically typed for up to 40 clinically important antigens. Thus the identification of many antibody specificities remains impossible when using reagent RBCs with only limited information about their antigens. To improve the pre-transfusion diagnostics, we developed antibody identification panels with reagent RBCs serologically typed for 26 antigens and additionally genotyped for 30 blood group alleles. Methods: The reagent RBCs in the panels were characterized serologically for the clinically most significant 'standard' antigens. The reagent RBC donors were additionally genotyped by using in-house PCR-SSP methods. The antibody identification was performed in the indirect antiglobulin test using untreated and papain-treated RBCs in the gel technique. Antibodies identified due to the genotype information were confirmed by serology using appropriate reference RBCs. Results: Within a time period of 3 years and 8 months, 16,878 blood samples from 8,467 patients were tested in our reference laboratory. In total, 21 different antibodies from 10 different blood group systems could be identified in 126 patients (1.5%) due to the genotype information obtained for the reagent RBCs. Antibodies to antigens from the Knops system (53 patients; 42%, 8 patients with anti-Knb) and to Cartwright antigens (31 patients; 25%) were the most frequent. Conclusion: The use of genotyped reagent RBCs in antibody identification panels extends the range of detectable antibody specificities, accelerates the antibody identification, and improves the pre-transfusion diagnostics. PMID- 30283272 TI - Extended Donor Typing by Pooled Capillary Electrophoresis: Impact in a Routine Setting. AB - Background: PCR with sequence-specific priming using allele-specific fluorescent primers and analysis on a capillary sequencer is a standard technique for DNA typing. We aimed to adapt this method for donor typing in a medium-throughput setting. Methods: Using the Extract-N-Amp PCR system, we devised a set of eight multiplex allele-specific PCR with fluorescent primers for Fya/Fyb, Jka/Jkb, M/N, and S/s. The alleles of a gene were discriminated by the fluorescent color; donor and polymorphism investigated were encoded by product length. Time, cost, and routine performance were collated. Discrepant samples were investigated by sequencing. The association of new alleles with the phenotype was evaluated by a step-wise statistical analysis. Results: On validation using 312 samples, for 1.1% of antigens (in 5.4% of samples) no prediction was obtained. 99.96% of predictions were correct. Consumable cost per donor were below EUR 2.00. In routine use, 92.2% of samples were successfully predicted. Discrepancies were most frequently due to technical reasons. A total of 11 previously unknown alleles were detected in the Kell, Lutheran, and Colton blood group systems. In 2017, more than 20% of the RBC units prepared by our institution were from donors with predicted antigen status. A steady supply of Yt(a-), Co(a-) and Lu(b-) RBC units was ensured. Conclusions: Pooled capillary electrophoresis offers a suitable alternative to other methods for extended donor DNA typing. Establishing a large cohort of typed donors improved transfusion support for patients. PMID- 30283274 TI - Rh-Matched Transfusion through Molecular Typing for beta-Thalassemia Patients Is Required and Feasible in Chinese. AB - Background: Molecular typing for RHCE blood group alleles has been established in many countries for patients and blood donors. In the Chinese literature nearly 80% of transfused patients with alloimmunization have antibodies specific for antigens of the Rh blood group system. We investigated if it is feasible to match packed red blood cells (RBCs) for Chinese beta-thalassemia patients by RHCE genotyping. Methods: In this study, 481 patients with beta-thalassemia were enrolled. They were genotyped for RHCE alleles by a simple PCR method with sequence-specific primers (PCR-SSP). Among these patients, 203 continuously received RBCs of the identical Rh subgroups according to the genotyping results for at least 3 months. Subsequently, their phenotypes were tested through a micro column gel card method. For validation purposes, 400 donors were serologically typed with the same technology, of which 164 were genotyped too. Finally, the C, c, E, and e frequencies and the feasibility of the simple genotyping method were analyzed. Results: All patients showed mixed-field agglutination in the Rh subgroup gel cards before the same Rh subgroups in blood donors were selected for blood transfusion. The results, however, lacked mixed-field agglutination in all 203 cases after transfusion with RBC concentrates selected for the patient's C, c, E, and e antigens for at least 3 months. The genotyping results of 164 donors were all consistent with the serological results. Whole coding regions of RHCE were sequenced in 7 individuals with weak c, E, or e antigens. In only one sample we observed a 1059G>A nucleotide mutation coding for a truncated RhCE polypeptide (GenBank KT957625), in the other 6 samples no sequence variant was found. Both patients and donors were predominantly CcEe and CCee, with a prevalence of 55.3% and 24.9% for patients or 49.3% and 31.3% for donors, respectively. It revealed that about 80% of Chinese could receive Rh-matched RBCs easily. Conclusion: A simple RHCE genotyping technique is safe enough for Rh-matched transfusion of beta-thalassemia patients in Chinese Han.

AB - Background: High-frequency blood group antigens (HFA) are present in >90% of the human population, according to some reports even in >99% of individuals. Therefore, patients lacking HFA may become challenging for transfusion support because compatible blood is hardly found, and if the patient carries alloantibodies, the cross-match will be positive with virtual every red cell unit tested. Methods: In this study, we applied high-throughput blood group SNP genotyping on >37,000 Swiss blood donors, intending to identify homozygous carriers of low-frequency blood group antigens (LFA). Results: 326 such individuals were identified and made available to transfusion specialists for future support of patients in need of rare blood products. Conclusion: Thorough comparison of minor allele frequencies using population genetics revealed heterogeneity of allele distributions among Swiss blood donors which may be explained by the topographical and cultural peculiarities of Switzerland. Moreover, geographically localized donor subpopulations are described which contain above-average numbers of individuals carrying rare blood group genotypes.

AB - The development of red blood cell (RBC) alloantibodies and autoantibodies complicates transfusion therapy in sickle cell disease (SCD) patients. In an effort to reduce the risk of alloimmunization, some strategies have been used to provide antigen-matched RBC transfusions to patients with SCD in Brazil, including molecular matching in 3 levels: RH and K matching; extended matching (RH, KEL, FY, JK, MNS, DI), and extended matching including RHD and RHCE variant alleles. Molecular matching has shown clinical benefits to the patients with SCD, contributing significantly to reduce the rates of alloimmunization. Improvements in the clinical outcomes of the patients have also been observed as shown by an increase in their hemoglobin levels and reduction in their percentage of hemoglobin S as well as better in vivo RBC survival and diminished frequency of transfusions. However, prevention of RBC alloimmunization still remains a challenge in Brazil due to the difficulty to fulfill all transfusion requests of the patients with antigen-matching units, inaccuracy of RBC phenotyping, RBC transfusions outside the institution where the patient is treated, advanced age of some patients, the RBC antigen discrepancy between donors and recipients, and the presence of RH variants. PMID- 30283276 TI - Genotyping in Sickle Cell Disease Patients: The French Strategy. AB - This review presents the French strategy for blood group genotyping in high responder and newly diagnosed sickle cell disease (SCD) patients. In addition to FY, JK, and MNS genotyping, the RH blood group system is now explored in SCD patients in France. Molecular typing has been used for the deduction of partial RH2 (C) antigens since 2010, and the gradual implementation of systematic RHD and RHCE genotyping nationwide was initiated in late 2014. In our laboratory, 962 RH:2 (C-positive) SCD patients have been tested since 2010, and 1,148 SCD patients of all RH phenotypes have been genotyped for clinically relevant alleles of RHD and RHCE since late 2014. PMID- 30283277 TI - Transfusion Support of Minority Patients: Extended Antigen Donor Typing and Recruitment of Minority Blood Donors. AB - One of the most important and persistent complications of blood transfusion is red blood cell (RBC) alloimmunization. When a patient is exposed to RBC antigens that differ from their own they can form alloantibodies to these foreign antigens. Blood group antigens are highly conserved and follow ancestral patterns of inheritance that may demonstrate population restriction. Minority populations who require chronic transfusion are at particularly high risk of alloimmunization when the blood donor population does not share the same ancestral background, resulting in exposure to non-self RBC antigens. It is incumbent on blood collectors to support patients with risk factors for alloimmunization as well as patients who have already formed alloantibodies. Increasing utilization of RBC genotyping may represent an opportunity to improve access to RBC units from donors that match the extended RBC phenotype of all possible patients. PMID- 30283278 TI - Multimodality Treatment of a Colorectal Cancer Stage IV Patient with FOLFOX-4, Bevacizumab, Rigvir Oncolytic Virus, and Surgery. AB - Colorectal cancer is one of the most commonly diagnosed cancers worldwide. The treatment consists of surgical resection, systemic chemotherapy, and new biological agents. One more recently emerging treatment option is oncolytic virotherapy. Although the use of the new treatment methods shows improved overall and progression-free survival, in general, even with the new treatments, mortality remains high and combinations of treatments should be sought to treat patients with colorectal cancer. Here we report a stage IV colorectal cancer patient who received multimodality treatment including bevacizumab, FOLFOX-4, surgery, and the oncolytic virus Rigvir. The patient shows complete pathological remission and remains stable 7.7 years after initial diagnosis. The possible benefits of combining Rigvir oncolytic virus and bevacizumab should be investigated since in vitro research suggests that anti-angiogenesis agents improve viral distribution by altering the microenvironment of the tumor. PMID- 30283279 TI - Glycogen Hepatopathy: A Rare and Underrecognized Cause of Recurrent Transaminitis in Patients with Uncontrolled Type 2 Diabetes Mellitus. AB - Glycogen hepatopathy (GH), characterized by reversible transaminitis and hepatomegaly, results from excessive accumulation of glycogen in hepatocytes. GH has been well described in the literature as a rare cause of transaminitis in children and young patients with uncontrolled type 1 diabetes mellitus and has rarely been reported in type 2 diabetic patients. Hyperglycemia and hyperinsulinemia are believed to be a metabolic substrate for hepatic glycogen accumulation and in order to cause glycogen hepatotoxicity. We present the case of a 54-year-old woman with poorly controlled insulin-dependent type 2 diabetes who was hospitalized twice within 1 month with diabetic ketoacidosis/hyperosmolar hyperglycemic state and reversible transaminitis. Interestingly, she had normal liver function tests performed at the time of admission and transaminitis was noted 1 day later, after she was treated with high doses of intravenous insulin therapy. Subsequently, liver enzymes recovered to normal levels with optimization of glucose control. PMID- 30283281 TI - Lethal Bleeding from a Duodenal Cancerous Ulcer Communicating with the Superior Mesenteric Artery in a Patient with Pancreatic Head Cancer. AB - Pancreatic cancer often invades the duodenum and causes obstruction, but rarely causes massive duodenal bleeding. A 68-year-old male was admitted to our hospital because of vomiting. Enhanced abdominal CT showed a hypovascular tumor with air bubbles in the uncinate process of the pancreas. The tumor invaded the duodenum and metastasized to the liver and peritoneum. The main trunk of the superior mesenteric artery (SMA) was circumferentially involved. After admission, he had hematemesis and melena. Emergency gastroduodenoscopy revealed pulsating vessels in the third portion of the duodenum and he eventually experienced hemorrhagic shock. Severe bleeding occurred from his mouth and anus like a catastrophic flood. It was difficult to sustain blood pressure even with massive blood transfusion with pumping. After insertion of an intra-aortic balloon occlusion catheter, the massive bleeding was eventually stopped. Although we attempted interventional radiography, aortography revealed direct communication between the main SMA trunk and the duodenal lumen. The tumor was considered anatomically and oncologically unresectable. Thus, we did not perform further intervention. The patient died 2 h after angiography. Herein, we report the case of pancreatic head cancer causing lethal bleeding associated with tumor-involved SMA. Duodenal bleeding associated with pancreatic cancer invasion should be considered as an oncogenic emergency.

AB - Atrial fibrillation (AF) is the most common cardiac arrhythmia, and cryoballoon ablation was developed as a new treatment modality for symptomatic AF. Gastroparesis is rarely reported as a transient complication of ablation, and its frequency and risk are not clear. We experienced a rare case of gastroparesis after cryoballoon ablation followed by medication-induced recovery within 6 months. PMID- 30283282 TI - A Young Adult Patient with Nonalcoholic Steatohepatitis Developed Severe Gastroesophageal Varices Associated with Severe Obesity and Diabetes Mellitus. AB - Obesity is a major contributor to insulin resistance and nonalcoholic fatty liver disease, which is the most common cause of chronic liver diseases. Nonalcoholic steatohepatitis (NASH) can progress to liver cirrhosis and end-stage liver diseases. Some cases already show severe liver fibrosis at the time of diagnosis. We present the case of a 44-year-old male with overt obesity who was admitted with hematemesis due to the rupture of gastric varices. We diagnosed him with NASH with severe liver fibrosis. This case shows that we should be concerned about the progression of liver fibrosis due to NASH associated with severe obesity even in young patients. PMID- 30283283 TI - Peroral Endoscopic Myotomy in Diffuse Thickened Esophageal Wall in an Adolescent. AB - Achalasia is an extremely rare pathology in children. Peroral endoscopic myotomy (POEM) is the gold standard for the surgical treatment of achalasia in adults, but only a limited number of cases of achalasia treatment using POEM in children have been published in the literature. Sometimes, high-resolution manometry signs of achalasia can mimic diffuse esophageal leiomyoma. This case report represents the first known successful performance of POEM on a 15-year-old female with diffuse thickening of the esophagus with signs and symptoms of achalasia and suspicion for Alport syndrome associated with diffuse esophageal leiomyoma. PMID- 30283284 TI - Simultaneous Resection for Synchronous Double Primary Cancers of the Pancreas and the Liver. AB - Simultaneous resection of synchronous hepatocellular carcinoma (HCC) and pancreatic ductal adenocarcinoma (PDAC) is extremely rare. Case 1 is a 64-year old woman, who had undergone anterior resection for rectal cancer 3 years earlier was pointed out to have a cystic tumor in the pancreatic tail and a solitary tumor in the liver. CT revealed a hypovascular tumor in the pancreatic tail and a liver tumor with early enhancement. With a diagnosis of simultaneous HCC and PDAC, she underwent laparotomy, in which intraoperative frozen section examination of the liver was compatible with HCC. Therefore, she underwent hepatic resection as well as distal pancreatectomy and splenectomy. The patient received adjuvant chemotherapy with S-1 and remains well with no evidence of tumor recurrence as of 28 months after resection. Case 2 is a 73-year-old man with sustained viral response to antiviral treatment for hepatitis C virus, who was pointed out to have a tumor in the pancreatic head and a solitary tumor in the liver. Gadoxetic acid-enhanced MRI exhibited enhancement compatible with HCC. With a diagnosis of concomitant HCC and PDAC, surgery was performed. Intraoperative frozen section examination was compatible with HCC, for which a pancreaticoduodenectomy was performed. The patient received adjuvant chemotherapy with S-1 and remains well with no evidence of tumor recurrence as of 16 months after resection. In conclusion, we describe 2 cases of hepato-pancreatectomy for synchronous double primary cancers of the pancreas and the liver, where exclusion of the liver tumor as a metastatic lesion from the pancreatic cancer is important. PMID- 30283285 TI - Arterial Pseudoaneurysm within a Pancreatic Pseudocyst. AB - The formation of pancreatic pseudocysts and (pseudo-)aneurysms of intestinal vessels are rare but life-threatening complications in acute and chronic pancreatitis. Here we report the rare case of a patient suffering from chronic pancreatitis with an arterial pseudoaneurysm within a pancreatic pseudocyst and present its successful therapeutic management by angioembolization to prevent critical bleeding. A 67-year-old male with a history of chronic pancreatitis presented with severe acute abdominal pain and vomiting to the emergency department. Seven weeks prior to the present admission, a CT scan had displayed a pancreatic pseudocyst with a maximum diameter of 53 mm. A laboratory examination revealed an elevated white blood cell count (15.40 * 103/MUL), as well as elevated serum lipase (191 U/L), bilirubin (1.48 mg/dL), and blood glucose (353 mg/dL) levels. Sonographically, the previously described pancreatic pseudocyst revealed a slightly increased maximum diameter of 65 mm and an inhomogeneous echo of the cystic content. A contrast-enhanced CT scan showed a further increase in maximum diameter to 70 mm of the known pseudocyst. Inside the pseudocyst, a pseudoaneurysm originating from the splenic artery with a maximum diameter of 41 mm was visualized. After interdisciplinary consultation, prophylactic coil embolization of the splenic artery was immediately performed. The pseudoaneurysm was shut off from blood supply by back-door/front-door occlusion employing 27 coils, resulting in complete exclusion of the pseudoaneurysm from the circulation. Pseudoaneurysms are a rare complication of acute and chronic pancreatitis which has been shown to be efficiently treated by coil embolization. PMID- 30283286 TI - Erratum. AB - [This corrects the article DOI: 10.1159/000486390.]. PMID- 30283287 TI - Posterior Reversible Encephalopathy Syndrome following Ustekinumab Induction for Crohn's Disease. AB - Biological agents are frequently used in the management of inflammatory bowel disease, and it is important to understand the potential adverse effects of these therapies. Ustekinumab is a human monoclonal antibody that interferes with interleukin-12 and -23 cytokine signaling and is approved for the treatment of moderate to severe Crohn's disease. We report 2 cases of neurological adverse events, one of which is consistent with posterior reversible encephalopathy syndrome (PRES), in the setting of ustekinumab therapy for Crohn's disease. The first patient had a seizure and classic neuroimaging features of PRES following induction with ustekinumab. The second patient presented with acute encephalopathy and atypical imaging findings concerning for PRES after ustekinumab induction. Both patients recovered fully following cessation of ustekinumab therapy. PRES associated with ustekinumab is uncommon, but must be a consideration in Crohn's disease patients receiving this therapy who present with focal neurological symptoms or change in mentation.

AB - Serrated polyps are most commonly located in the colorectum and have been well recognized as an important precursor lesion for colorectal cancer. Serrated adenoma in the small intestine has been reported more rarely but may represent a distinct morphological and biological subtype with malignant potential. Here, we present the case of a 65-year-old female who underwent double-balloon enteroscopy due to obscure gastrointestinal bleeding. A polyp sized 3.5 * 2.0 cm with a long pedicle in the jejunum, located 50 cm distal to the Treitz ligament, was detected. Endoscopic mucosal resection was done. The pathological results revealed a traditional serrated adenoma sized 3.5 * 2.2 cm. PMID- 30283289 TI - Long-Term Survival in Gastroesophageal Junction Adenocarcinoma: Ramucirumab.

A 64-year-old man with gastroesophageal junction adenocarcinoma and liver metastases received first-line folinic acid, 5-fluorouracil plus oxaliplatin (FOLFOX) following jejunostomy. On liver progression, he enrolled in RAINBOW (April 2012), receiving ramucirumab. In November 2013, positron emission tomography scan was consistent with complete metabolic response, confirmed by a follow-up scan in March 2016. PMID- 30283290 TI - Successful Laparoscopy-Assisted Resection of the Descending Colon in a Patient with Multiple Large Renal Cysts and Stricture of the Colon due to Ischemic Colitis. AB - Large pathological structures in the abdominal cavity curb the application of laparoscopic surgery. This case report describes a successful laparoscopy assisted colectomy for benign colon disease in a patient with multiple large renal cysts. An 82-year-old man was referred to our department for treatment of stenosis of descending colon secondary to ischemic colitis. An abdominal computed tomography revealed multiple large renal cysts occupying a large proportion of the peritoneal cavity. To minimize the postoperative recovery period, laparoscopic surgery was planned despite the renal cysts. After inserting access ports, the walls of the several renal cysts were fenestrated with an electronic scalpel and the serous fluid was aspirated to enable continuation of the laparoscopic colectomy. The left colon was mobilized and extracted through an incision at the umbilicus, and the affected part of the colon was resected safely. The patient's postoperative course was uneventful, and the present case suggests that laparoscopy-assisted colectomy can be performed safely even in patients with multiple large renal cysts. PMID- 30283291 TI - Lorazepam as a Cause of Drug-Induced Liver Injury. AB - Lorazepam is a benzodiazepine derivative that is globally used for the therapy of anxiety and insomnia. A 51-year-old Japanese man with yellowish discoloration of the eyes and skin and pruritus was admitted due to liver dysfunction. He had taken lorazepam approximately 5 months prior to this admission. The clinical presentation and pathologic findings in the liver were consistent with drug induced liver injury. After cessation of lorazepam, treatment with Stronger neo minophagen C and ursodeoxycholic acid was started, and his liver injury resolved after 59 days. This case must serve as a warning to physicians to be aware of the possibility of unexpected liver injury caused by lorazepam. PMID- 30283292 TI - Melatonin Protects Against Neuronal Apoptosis via Suppression of the ATF6/CHOP Pathway in a Rat Model of Intracerebral Hemorrhage. AB - Neuronal apoptosis is an important factor accounting for the poor outcomes of intracerebral hemorrhage (ICH). This study first showed that inhibition of activating transcription factor 6 (ATF6) could alleviate secondary brain injury through anti-apoptosis after ICH in rats. Melatonin, ATF6 and CCAAT/enhancer binding protein homologous protein (CHOP) siRNAs were applied in this study. Brain edema, neurological functions, blood-brain barrier (BBB) integrity were evaluated at 24 h after ICH. Western blot analysis was used to evaluate the protein level of target proteins (ATF6, CHOP, Bip, Bcl-2, Bax, and cleaved caspase-3). Reverse transcription-polymerase chain reaction (RT-PCR) was used to assess the mRNA level of ATF6, CHOP and cleaved caspase-3. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) and caspase 3 immunofluorescence staining were applied to evaluate the neuronal cell death. The results suggested that the levels of ATF6 and its downstream protein, CHOP, were upregulated and reached the peak at 24 h after ICH. ATF6 was highly expressed in neurons. The administration of melatonin significantly decreased the mRNA and protein levels of ATF6, and its downstream targets, CHOP and cleaved caspase-3, but increased the Bcl-2/Bax ratio, which ameliorated the neurological functions. The CHOP siRNA significantly reversed the pro-apoptotic effect induced by the increased ATF6 level after ICH. Melatonin could protect against neuronal apoptosis via suppression of ATF6/CHOP arm of ER-stress-response pathway.

PMID- 30283294 TI - Effects of Non-invasive Neuromodulation on Executive and Other Cognitive Functions in Addictive Disorders: A Systematic Review. AB - Background: In order to improve the current treatment of addictive disorders non invasive neuromodulation over the dorsolateral prefrontal cortex (DLPFC) has gained attention. The DLPFC is crucially involved in executive functioning, functions which are related to the course of addictive disorders. Non-invasive stimulation of the DLPFC may lead to changes in executive functioning. Currently an overview of effects of neuromodulation on these functions is lacking. Therefore, this systematic review addresses the effects of non-invasive neuromodulation on executive functioning in addictive disorders. Methods: The current review is conducted and reported in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses for Protocols 2015 (PRISMA-P 2015) guidelines and has been registered in PROSPERO International Prospective Register of Systematic Reviews (https://www.crd.york.ac.uk/prospero/, registration number: CRD42018084157). Original articles were searched using the Ovid MEDLINE, Embase and PsycINFO database. Results: The systematic search resulted in 1,228 unique studies, of which sixteen were included in the current review. Some of these studies do not address the classic definition of executive functions, but another cognitive function. However, they were included in this review since the field is small and still under development and we aim to give an inclusive overview in its broadest sense. The following executive and other cognitive functioning domains were assessed: attention, cognitive flexibility, response inhibition, memory and learning, problem solving, social cognition, risk taking, cognitive bias modification and overall executive functioning. The executive function domain most positively affected was social cognition followed by memory & learning, response inhibition, cognitive flexibility and attention. Conclusions: The studies addressed in the current review used a large variability of stimulation protocols and study designs which complicates comparability of the results. Nevertheless, the results of these studies are promising in light of improvement of current treatment. Therefore, we recommend future studies that compare the effect of different types of stimulation, stimulation sides and number of stimulation sessions in larger clinical trials. This will significantly increase the comparability of the studies and thereby accelerate and clarify the conclusion on whether non-invasive neuromodulation is an effective add-on treatment for substance dependence. PMID- 30283296 TI - Development and Characterization of PEDOT:PSS/Alginate Soft Microelectrodes for Application in Neuroprosthetics. AB - Reducing the mechanical mismatch between the stiffness of a neural implant and the softness of the neural tissue is still an open challenge in neuroprosthetics. The emergence of conductive hydrogels in the last few years has considerably widened the spectrum of possibilities to tackle this issue. Nevertheless, despite the advancements in this field, further improvements in the fabrication of conductive hydrogel-based electrodes are still required. In this work, we report the fabrication of a conductive hydrogel-based microelectrode array for neural recording using a hybrid material composed of poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate), and alginate. The mechanical properties of the conductive hydrogel have been investigated using imaging techniques, while the electrode arrays have been electrochemically characterized at each fabrication step, and successfully validated both in vitro and in vivo. The presence of the conductive hydrogel, selectively electrodeposited onto the platinum microelectrodes, allowed achieving superior electrochemical characteristics, leading to a lower electrical noise during recordings. These findings represent an advancement in the design of soft conductive electrodes for neuroprosthetic applications. PMID- 30283295 TI - Fourier-Transform Infrared Imaging Spectroscopy and Laser Ablation -ICPMS New Vistas for Biochemical Analyses of Ischemic Stroke in Rat Brain. AB - Objective: Stroke is the main cause of adult disability in the world, leaving more than half of the patients dependent on daily assistance. Understanding the post-stroke biochemical and molecular changes are critical for patient survival and stroke management. The aim of this work was to investigate the photo thrombotic ischemic stroke in male rats with particular focus on biochemical and elemental changes in the primary stroke lesion in the somatosensory cortex and surrounding areas, including the corpus callosum. Materials and Methods: FT-IR imaging spectroscopy and LA-ICPMS techniques examined stroke brain samples, which were compared with standard immunohistochemistry studies. Results: The FTIR results revealed that in the lesioned gray matter the relative distribution of lipid, lipid acyl and protein contents decreased significantly. Also at this locus, there was a significant increase in aggregated protein as detected by high levels Abeta1-42. Areas close to the stroke focus experienced decrease in the lipid and lipid acyl contents associated with an increase in lipid ester, olefin, and methyl bio-contents with a novel finding of Abeta1-42 in the PL-GM and L-WM. Elemental analyses realized major changes in the different brain structures that may underscore functionality. Conclusion: In conclusion, FTIR bio-spectroscopy is a non-destructive, rapid, and a refined technique to characterize oxidative stress markers associated with lipid degradation and protein denaturation not characterized by routine approaches. This technique may expedite research into stroke and offer new approaches for neurodegenerative disorders. The results suggest that a good therapeutic strategy should include a mechanism that provides protective effect from brain swelling (edema) and neurotoxicity by scavenging the lipid peroxidation end products. PMID- 30283297 TI - The Contribution and Therapeutic Potential of Epigenetic Modifications in Alzheimer's Disease. AB - Alzheimer's disease is a progressive neurodegenerative disorder, affecting 50 million people worldwide, for which there is no cure, or effective treatment. Individuals suffering from Alzheimer's show a decline in cognition over time beginning with memory loss and ultimately leading to severe dementia, and inability to care for themselves. The cause of Alzheimer's is not known but likely involves a combination of genetic, biochemical, and environmental factors. Some genes have been identified as risk factors but monozygotic twins discordant for Alzheimer's disease suggest other factors must contribute to development of the disease. Investigation on epigenetic marks including DNA methylation and post translational modifications of histones have shown that the patterns of these modifications change with age in the human population. Though individuals show specific differences in epigenetic marks at the individual gene level, there is a consistent pattern of epigenetic changes at the genome scale across the population. Similar changes have been identified in patients with Alzheimer's disease, though these occur at an earlier age compared to healthy individuals. The early cognitive impairment in Alzheimer's disease can be mistaken for premature ageing correlating with the timing of epigenetic changes occurring at a younger age in individuals with Alzheimer's. Such observations suggest that the epigenetic changes may contribute to disease pathology. Exactly how epigenetic modifications contribute to specific aspects of Alzheimer's disease is the focus of many researcher groups across the world. A number of drugs are available that inhibit the enzymes that modify chromatin and change the epigenetic landscape of the genome. Therefore, an understanding of the role of chromatin modifications in Alzheimer's could offer an opportunity for novel therapeutic strategies. Research using animal models of Alzheimer's suggests that the epigenetic changes in Alzheimer's disease may have a profound impact on cognition and underlie cognitive impairment while there is no clear evidence that they might contribute directly to neuronal loss.

At present, the mechanisms underlying the defect of HTT and the development of HD remain largely unclear. However, increasing evidence shows the presence of enhanced oxidative stress in HD patients. In this review article, we focus on the role of oxidative stress in the pathogenesis of HD and discuss mediators and potential mechanisms involved in mutant HTT-mediated oxidative stress generation and progression. Furthermore, we emphasize the role of the unicellular organism Saccharomyces cerevisiae in investigating mutant HTT-induced oxidative stress. Overall, this review article provides an overview of the latest findings regarding oxidative stress in HD and potential therapeutic targets for HD. PMID- 30283299 TI - Molecular Details of Retinal Guanylyl Cyclase 1/GCAP-2 Interaction. AB - The rod outer segment guanylyl cyclase 1 (ROS-GC1) is an essential component of photo-transduction in the retina. In the light-induced signal cascade, membrane bound ROS-GC1 restores cGMP levels in the dark in a calcium-dependent manner. With decreasing calcium concentration in the intracellular compartment, ROS-GC1 is activated via the intracellular site by guanylyl cyclase-activating proteins (GCAP-1/-2). Presently, the exact activation mechanism is elusive. To obtain structural insights into the ROS-GC1 regulation by GCAP-2, chemical cross linking/mass spectrometry studies using GCAP-2 and three ROS-GC1 peptides were performed in the presence and absence of calcium. The majority of cross-links were identified with the C-terminal lobe of GCAP-2 and a peptide comprising parts of ROS-GC1's catalytic domain and C-terminal extension. Consistently with the cross-linking results, surface plasmon resonance and fluorescence measurements confirmed specific binding of this ROS-GC peptide to GCAP-2 with a dissociation constant in the low micromolar range. These results imply that a region of the catalytic domain of ROS-GC1 can participate in the interaction with GCAP-2. Additional binding surfaces upstream of the catalytic domain, in particular the juxtamembrane domain, can currently not be excluded. PMID- 30283300 TI - Peroxisome Proliferator Activated Receptor Agonists Modulate Transposable Element Expression in Brain and Liver. AB - Peroxisome proliferator activated receptors (PPARs) are nuclear hormone receptors that act as transcription factors in response to endogenous lipid messengers. The fibrates and thiazolidinediones are synthetic PPAR agonists used clinically to treat dyslipidemia and Type 2 Diabetes Mellitus, respectively, but also improve symptoms of several other diseases. Transposable elements (TEs), repetitive sequences in mammalian genomes, are implicated in many of the same conditions for which PPAR agonists are therapeutic, including neurodegeneration, schizophrenia, and drug addiction. We tested the hypothesis that there is a link between actions of PPAR agonists and TE expression. We developed an innovative application of microarray data by mapping Illumina mouse WG-6 microarray probes to areas of the mouse genome that contain TEs. Using this information, we assessed the effects of systemic administration of three PPAR agonists with different PPAR subtype selectivity: fenofibrate, tesaglitazar, and bezafibrate, on TE probe expression in mouse brain [prefrontal cortex (PFC) and amygdala] and liver. We found that fenofibrate, and bezafibrate to a lesser extent, up-regulated probes mapped to retrotransposons: Short-Interspersed Elements (SINEs) and Long-Interspersed Elements (LINEs), in the PFC. Conversely, all PPAR agonists down-regulated LINEs and tesaglitazar and bezafibrate also down-regulated SINEs in liver. We built gene coexpression networks that partitioned the diverse transcriptional response to PPAR agonists into groups of probes with highly correlated expression patterns (modules). Most of the differentially expressed retrotransposons were within the same module, suggesting coordinated regulation of their expression, possibly by PPAR signaling. One TE module was conserved across tissues and was enriched with genes whose products participate in epigenetic regulation, suggesting that PPAR agonists affect TE expression via epigenetic mechanisms. Other enriched functional categories included phenotypes related to embryonic development and learning and memory, suggesting functional links between these biological processes and TE expression. In summary, these findings suggest mechanistic relationships between retrotransposons and PPAR agonists and provide a basis for future exploration of their functional roles in brain and liver. PMID- 30283302 TI - The Effects of Chronic Stress on Migraine Relevant Phenotypes in Male Mice. AB - Migraine is a disabling neurological disorder affecting 12% of the world's population. Stress is a major reported trigger and exacerbator of migraine. We evaluated the effects of two chronic stress paradigms on migraine relevant phenotypes in male C57Bl/6 mice. Methods: Fifty six mice were used in a 14 day social defeat stress (SDS) and twenty three mice were used in a 40 day chronic variable stress (CVS) paradigm. Anxiety measures were evaluated using the open field and elevated plus maze (EPM) tests. Migraine relevant phenotypes were evaluated using the nitroglycerin (NTG) and cortical spreading depression (CSD) models. Results: Stress sensitive SDS mice and chronically stressed CVS mice showed decreased exploration in the open field and reduced time spent in the open arms of the EPM compared to controls. Stress sensitive and resilient SDS mice had increased serum corticosterone levels, and stressed mice in the CVS paradigm had decreased weight gain compared to controls, providing combined behavioral and physiological evidence of a stress response. In the CVS paradigm but not the SDS paradigm, the stressed group showed a significant decrease in baseline mechanical withdrawal threshold compared to controls. All groups showed a significant reduction in withdrawal threshold after treatment with NTG, but the reduction was not larger in SDS or CVS than in controls. Interestingly, stress resilient SDS mice showed a rapid recovery from NTG effects that was not seen in other groups. No difference in CSD frequency or velocity was seen between stress and control mice in either stress paradigms. Conclusion: We observed distinct effects of stress on generalized pain response, migraine relevant pain, and migraine relevant excitability. CVS but not SDS was associated with a reduced mechanical withdrawal threshold, consistent with a generalized pain response to chronic stress. Neither SDS nor CVS exacerbated phenotypes considered specifically relevant to migraine - withdrawal to NTG, and susceptibility to CSD. However, the significantly reduced response of stress resilient mice to the NTG stimulus may represent a specific migraine-resistant phenotype. PMID- 30283301 TI - Roles of Post-translational Modifications in Spinocerebellar Ataxias. AB - Post-translational modifications (PTMs), including phosphorylation, acetylation, ubiquitination, SUMOylation, etc., of proteins can modulate protein properties such as intracellular distribution, activity, stability, aggregation, and interactions. Therefore, PTMs are vital regulatory mechanisms for multiple cellular processes. Spinocerebellar ataxias (SCAs) are hereditary, heterogeneous, neurodegenerative diseases for which the primary manifestation involves ataxia. Because the pathogenesis of most SCAs is correlated with mutant proteins directly or indirectly, the PTMs of disease-related proteins might functionally affect SCA development and represent potential therapeutic interventions. Here, we review multiple PTMs related to disease-causing proteins in SCAs pathogenesis and their effects. Furthermore, we discuss these PTMs as potential targets for treating SCAs and describe translational therapies targeting PTMs that have been published. PMID- 30283303 TI - Putative Neural Network Within an Olfactory Sensory Unit for Nestmate and Non nestmate Discrimination in the Japanese Carpenter Ant: The Ultra-structures and Mathematical Simulation. AB - Ants are known to use a colony-specific blend of cuticular hydrocarbons (CHCs) as a pheromone to discriminate between nestmates and non-nestmates and the CHCs were sensed in the basiconic type of antennal sensilla (S. basiconica). To investigate the functional design of this type of antennal sensilla, we observed the ultra structures at 2D and 3D in the Japanese carpenter ant, Camponotus japonicus, using a serial block-face scanning electron microscope (SBF-SEM), and conventional and high-voltage transmission electron microscopes. Based on the serial images of 352 cross sections of SBF-SEM, we reconstructed a 3D model of the sensillum revealing that each S. basiconica houses > 100 unbranched dendritic processes, which extend from the same number of olfactory receptor neurons (ORNs). The dendritic processes had characteristic beaded-structures and formed a twisted bundle within the sensillum. At the "beads," the cell membranes of the processes were closely adjacent in the interdigitated profiles, suggesting functional interactions via gap junctions (GJs). Immunohistochemistry with anti innexin (invertebrate GJ protein) antisera revealed positive labeling in the antennae of C. japonicus. Innexin 3, one of the five antennal innexin subtypes, was detected as a dotted signal within the S. basiconica as a sensory organ for nestmate recognition. These morphological results suggest that ORNs form an electrical network via GJs between dendritic processes. We were unable to functionally certify the electric connections in an olfactory sensory unit comprising such multiple ORNs; however, with the aid of simulation of a mathematical model, we examined the putative function of this novel chemosensory information network, which possibly contributes to the distinct discrimination of colony-specific blends of CHCs or other odor detection. PMID- 30283304 TI - SK2 Channels Associate With mGlu1alpha Receptors and CaV2.1 Channels in Purkinje Cells. AB - The small-conductance, Ca2+-activated K+ (SK) channel subtype SK2 regulates the spike rate and firing frequency, as well as Ca2+ transients in Purkinje cells (PCs). To understand the molecular basis by which SK2 channels mediate these functions, we analyzed the exact location and densities of SK2 channels along the neuronal surface of the mouse cerebellar PCs using SDS-digested freeze-fracture replica labeling (SDS-FRL) of high sensitivity combined with quantitative analyses. Immunogold particles for SK2 were observed on post- and pre-synaptic compartments showing both scattered and clustered distribution patterns. We found an axo-somato-dendritic gradient of the SK2 particle density increasing 12-fold from soma to dendritic spines. Using two different immunogold approaches, we also found that SK2 immunoparticles were frequently adjacent to, but never overlap with, the postsynaptic density of excitatory synapses in PC spines. Co immunoprecipitation analysis demonstrated that SK2 channels form macromolecular complexes with two types of proteins that mobilize Ca2+: CaV2.1 channels and mGlu1alpha receptors in the cerebellum. Freeze-fracture replica double-labeling showed significant co-clustering of particles for SK2 with those for CaV2.1 channels and mGlu1alpha receptors. SK2 channels were also detected at presynaptic sites, mostly at the presynaptic active zone (AZ), where they are close to CaV2.1 channels, though they are not significantly co-clustered. These data demonstrate that SK2 channels located in different neuronal compartments can associate with distinct proteins mobilizing Ca2+, and suggest that the ultrastructural association of SK2 with CaV2.1 and mGlu1alpha provides the mechanism that ensures voltage (excitability) regulation by distinct intracellular Ca2+ transients in PCs. PMID- 30283307 TI - Brain Waves Evaluation of Sound Therapy in Chronic Subjective Tinnitus Cases Using Wavelet Decomposition. AB - Management and treatment of subjective tinnitus is an ongoing focus of research activities. One of the most viable assessments of such treatment is the evaluation of brain activity in addition to patient response and clinical assessment. This study focuses on sound therapy and evaluation of patients' electroencephalogram (EEG) in order to verify the potency of this approach. Broadband sound therapy was applied to nineteen participants aging from 25 to 64 and suffering from chronic subjective tinnitus to study the difference of brain activity, a) before fake treatment, b) after fake treatment and c) after the main treatment, using EEG and Visual Analog Scale (VAS) for evaluating Residual Inhibition (RI). Four features were extracted using 4-level wavelet decomposition with Symlet 8 as its mother wavelet. For the "After the main treatment" stage, the mean value of wavelet coefficients for the last wavelet level, which corresponded to delta band of EEG, was lower in the FC3 channel based on Two Sample T-Test with significance level of 0.01, as compared to the same channel of the "before the treatment" stage, for cases in which decreased tinnitus loudness were reported. PMID- 30283305 TI - Gap Junctions in the Nervous System: Probing Functional Connections Using New Imaging Approaches. AB - Gap junctions are channels that physically connect adjacent cells, mediating the rapid exchange of small molecules, and playing an essential role in a wide range of physiological processes in nearly every system in the body, including the nervous system. Thus, altered function of gap junctions has been linked with a plethora of diseases and pathological conditions. Being able to measure and characterize the distribution, function, and regulation of gap junctions in intact tissue is therefore essential for understanding the physiological and pathophysiological roles that gap junctions play. In recent decades, several robust in vitro and in vivo methods have been developed for detecting and characterizing gap junctions. Here, we review the currently available methods with respect to invasiveness, signal-to-noise ratio, temporal resolution and others, highlighting the recently developed chemical tracers and hybrid imaging systems that use novel chemical compounds and/or genetically encoded enzymes, transporters, channels, and fluorescent proteins in order to map gap junctions. Finally, we discuss possible avenues for further improving existing techniques in order to achieve highly sensitive, cell type-specific, non-invasive measures of in vivo gap junction function with high throughput and high spatiotemporal resolution. PMID- 30283306 TI - Functional Anatomy of the Inferior Longitudinal Fasciculus: From Historical Reports to Current Hypotheses. AB - The inferior longitudinal fasciculus (ILF) is a long-range, associative white matter pathway that connects the occipital and temporal-occipital areas of the brain to the anterior temporal areas. In view of the ILF's anatomic connections, it has been suggested that this pathway has a major role in a relatively large array of brain functions. Until recently, however, the literature data on these potential functions were scarce. Here, we review the key findings of recent anatomic, neuromodulation, and neuropsychological studies. We also summarize reports on how this tract is disrupted in a wide range of brain disorders, including psychopathologic, neurodevelopmental, and neurologic diseases. Our review reveals that the ILF is a multilayered, bidirectional tract involved in processing and modulating visual cues and thus in visually guided decisions and behaviors. Accordingly, sudden disruption of the ILF by neurologic insult is mainly associated with neuropsychological impairments of visual cognition (e.g., visual agnosia, prosopagnosia, and alexia). Furthermore, disruption of the ILF may constitute the pathophysiologic basis for visual hallucinations and socio emotional impairments in schizophrenia, as well as emotional difficulties in autism spectrum disorder. Degeneration of the ILF in neurodegenerative diseases affecting the temporal lobe may explain (at least in part) the gradual onset of semantic and lexical access difficulties. Although some of the functions mediated by the ILF appear to be relatively lateralized, observations from neurosurgery suggest that disruption of the tract's anterior portion can be dynamically compensated for by the contralateral portion. This might explain why bilateral disruption of the ILF in either acute or progressive disease is highly detrimental in neuropsychological terms. PMID- 30283309 TI - Ketamine Does Not Exert Protective Properties on Dopaminergic Neurons in the Lactacystin Mouse Model of Parkinson's Disease. AB - Parkinson's disease (PD) is an age-related neurodegenerative condition characterized by a progressive loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc). A loss of proteasome function participates to the pathogenesis of PD, leading to the development of rodent models in which a proteasome inhibitor is applied to the nigrostriatal pathway. We recently characterized the intranigral lactacystin (LAC) mouse model, leading to nigrostriatal degeneration, motor dysfunction and alpha-synuclein accumulation. In the present study, we compared the effect of two commonly used anesthetics for generating animal models of PD-i.e., ketamine (KET) and isoflurane (ISO)-on the vulnerability of mouse dopaminergic neurons to proteasome inhibition-induced degeneration. Both anesthetics have the potential to affect the susceptibility of the nigrostriatal pathway for toxin-induced degeneration, and are known to modulate dopamine (DA) homeostasis. Yet, their impact on nigrostriatal degeneration in the proteasome inhibition model has not been evaluated. Unilateral injection with LAC in the SNpc of mice induced motor impairment and significantly reduced the number of dopaminergic cells to ~55%, irrespective of the anesthetic used. However, LAC-induced striatal DA depletion was slightly affected by the choice of anesthetic, resulting in a significant increase in DA turnover in the ISO- but not in KET-treated mice. These results suggest that the extent of nigrostriatal dopaminergic neural loss caused by LAC is not influenced by the choice of anesthetic, and that compared to other PD models, KET is not neuroprotective in the LAC model. PMID- 30283308 TI - Palatable Food Dampens the Long-Term Behavioral and Endocrine Effects of Juvenile Stressor Exposure but May Also Provoke Metabolic Syndrome in Rats. AB - The juvenile period is marked by a reorganization and growth of important brain regions including structures associating with reward seeking behaviors such as the nucleus accumbens (NA) and prefrontal cortex (PFC). These changes are impacted by stressors during the juvenile period and may lead to a predisposition to stress induced psychopathology and abnormal development of brain reward systems. Like in humans, adult rodents engage certain coping mechanisms such as increases in the consumption of calorie-rich palatable foods to reduce stress, but this behavior can lead to obesity and metabolic disorders. In this study, we examined whether stressors during the juvenile period led to increased caloric intake when a palatable diet was accessible, and whether this diet attenuated adult stress responses. In addition, we examined if the stress buffering effects produced by the palatable diet were also accompanied by an offset propensity towards obesity, and by alterations in mRNA expression of dopamine (DA) receptors in the NA and PFC in adulthood. To this end, juvenile male Wistar rats underwent episodic stressor exposure (forced swim, elevated platform stress and restraint) on postnatal days (PD) 27-29 and received access to regular chow or daily limited access to a palatable diet until adulthood. At the age of 2 months, rats were tested on a social interaction test that screens for anxiety-like behaviors and their endocrine responses to an acute stressor. Animals were sacrificed, and their brains processed to detect differences in DA receptor subtype expression in the PFC and NA using qPCR. Results showed that rats that were stressed during the juvenile period displayed higher social anxiety and a sensitized corticosterone response as adults and these effects were attenuated by access to the palatable diet. Nevertheless, rats that experienced juvenile stress and consumed a palatable diet showed greater adiposity in adulthood. Interestingly, the same group displayed greater mRNA expression of DA receptors at the NA. This suggests that access to a palatable diet mitigates the behavioral and endocrine effects of juvenile stressor exposure in adulthood, but at the cost of metabolic imbalances and a sensitized dopaminergic system. PMID- 30283310 TI - A State of Alcohol Hangover Impedes Everyday Prospective Memory. AB - The aim of the current study was to investigate what impact a state of alcohol hangover (AH) has upon everyday prospective memory (PM; memory for future events/intentions). Previous research has shown that the AH has a detrimental effect upon cognitive abilities, including memory and attentional deficits. No published research articles to date have focused upon what impact AH might have upon everyday memory, of which PM is a good example. The current study compared an AH group (AHG) with a non-hangover group (NHG) on PM. Since other drug use, anxiety and depression can affect PM independent of the AH, these covariates were controlled for in the study. Fifty-eight young adults studying at university participated in this between-subjects design study-25 in the AHG and 33 in the NHG. The Prospective Remembering Video Procedure (PRVP) measured PM. The Acute Hangover Rating Scale confirmed a state of AH and a Digital Breath Analyzer Test measured their BAC. The Hospital Anxiety and Depression Scale gauged levels of anxiety and depression and a Recreational Drug Use Questionnaire (RDUQ) measured alcohol and other drug use. Anyone who reported having used an illicit substance (e.g., cannabis, ecstasy) or who smoked, were excluded from the study. After controlling for age, alcohol units per week, years spent drinking alcohol, anxiety and depression scores, a one-way analysis of covariance (ANCOVA) revealed that the AHG (mean = 5.16) recalled significantly fewer items on the PRVP than the NHG (mean = 7.51)-F (1,52) = 5.69, p < 0.05. Overall, it appeared that a state of AH significantly impaired PM, which was not attributable to age, alcohol use, or anxiety or depression indices. Given the importance of PM to everyday activities, such as remembering to keep appointments or to take an important medication on time, this finding may have farther-reaching implications. These findings should also be used to educate young adults and health professionals dealing with the consequences with regards the dangers of alcohol misuse.

PMID- 30283312 TI - Recurrent Granuloma Gluteale Infantum Secondary to Fecal Overflow Incontinence. AB - Granuloma gluteale infantum is a rare pediatric dermatological disorder of uncertain etiology. Suggested causes include fluorinated corticosteroids, Candida albicans, and irritant contact dermatitis. We present the case of a 3-year-old boy with recurrent episodes of granuloma gluteale infantum which resolved with treatment of his fecal overflow incontinence. As each recurrence correlated with a relapse of overflow incontinence, in this case the cause was irritant contact dermatitis from the liquid stool. This is the first reported case of recurrent granuloma gluteale infantum. PMID- 30283313 TI - A Case of Primary Cutaneous Basal Cell Carcinosarcoma. AB - A 94-year-old man consulted our hospital due to a rapidly growing tumor on the left cheek. The histological diagnosis of the tumor was basal cell carcinosarcoma, which was composed of intermingled epithelial and mesenchymal components. The former was basal cell carcinoma, while the latter was spindle cell sarcoma. The tumor was completely resected with a 3-mm margin and the patient remained free of local recurrence or distinct metastasis for 2 years. We report here a case of cutaneous basal cell carcinosarcoma and a review of the literature. PMID- 30283314 TI - Case Study of Onychomycosis Patients Treated with 1,064-nm Nd:YAG Laser. AB - Onychomycosis is the most frequent nail disease, with an estimated prevalence of 2-8%. Current treatment strategies include the use of oral and topical antifungals, despite low cure rates following these treatments. The objectives of this study were to assess the therapeutic response of patients with onychomycosis to 1,064-nm Nd:YAG laser treatment, the clinical evaluation method available for this therapy, and the possible side effects of this treatment. Twenty patients with onychomycosis underwent laser therapy. A total of 34 nails with onychomycosis were assessed according to the Onychomycosis Severity Index (OSI). This index generates scores that classify onychomycosis as mild, moderate, or severe. The OSI was determined before treatment and after a mean follow-up period of 8 months. The comparison between the initial and the final OSI for all 34 nails treated with laser therapy showed a significant difference; however, a low association was shown between these variables. A general reduction in the area of involvement and in the OSI numerical scores was observed. These data show a trend toward improvement in onychomycosis treated with 1,064-nm Nd:YAG laser. The OSI allowed an adequate clinical assessment of the response to laser therapy. Laser treatment did not cause marked discomfort in most patients, indicating that laser is a well-tolerated procedure. PMID- 30283315 TI - Hydrogen Sulfide and Hydrogen Sulfide-Synthesizing Enzymes Are Altered in a Case of Oral Adenoid Cystic Carcinoma. AB - Adenoid cystic carcinomas (ACC) constitute 1% of all head and neck malignancies and are very rare in the oral cavity. With < 60 oral ACCs described, their pathobiology is incompletely understood. Here, we report a case of oral cavity ACC in a 54-year-old woman. Since recent studies have demonstrated that several human tumors overexpress the hydrogen sulfide (H2S)-synthesizing enzymes cystathionine-beta-synthase (CBS), cystathionine gamma-lyase (CSE), and 3 mercaptopyruvate sulfurtransferase (3-MST), and also show dysregulated H2S levels, we examined these biomarkers in the oral ACC and compared the results to those of adjacent benign oral epithelium. Western blotting was used to compare the protein expression of CBS, CSE, 3-MST, nicotinamide phosphoribosyl transferase, and mitoNEET in ACC and adjacent benign oral mucosae. High performance liquid chromatography was used to quantify the differences in tissue H2S concentrations between the two biopsy types. We found that all the proteins examined here were increased in the ACC compared to adjacent benign oral mucosae. Interestingly, H2S concentrations were decreased approximately 30% in ACC compared to benign mucosae. Thus, in one example of this rare tumor type, the enzymes that synthesize H2S are increased, while tissue H2S levels are lower than those found in adjacent benign oral mucosae. Although limited to a single rare tumor type, to our knowledge this is the second time H2S concentrations have been directly quantified inside a human tumor. Last, our results may indicate that alterations in H2S synthesis and metabolism may be important in the pathobiology of ACC. PMID- 30283316 TI - Extracranial Metastases of a Cerebral Glioblastoma: A Case Report and Review of the Literature. AB - The glioblastoma, a malignant human brain tumor, is known for its devastating intracranial progress and its dismal prognosis. Whereas treatment and research are most prominently focused on the primary tumor lesion, in recent years evidence has accumulated that points to the rare occurrence of extracranial glioblastoma metastases. We here present a case of a female patient with a known glioblastoma who was detected to harbor multiple metastases in the bones, lung, pleura, liver, mesentery, and the subcutaneous soft tissue. Pathogenetically, these metastatic lesions developed most probably after a local progression of the left temporal glioblastoma through the skull base, thus getting access to the systemic lymphatics. Similar cases of extensive glioblastoma metastization, their putative underlying mechanisms, and implications for clinical care are discussed. PMID- 30283317 TI - Two Cases of Long-Term Survival of Advanced Colorectal Cancer with Synchronous Lung Metastases Treated with mFOLFOX6/XELOX + Bevacizumab. AB - Background: Colorectal cancer (CRC) with lung metastases has an unfavorable prognosis. However, nowadays, even advanced CRC can have a favorable outcome in certain cases. A complete response (CR) is a rare event in advanced CRC with lung metastases. Herein, we report 2 rare cases of advanced CRC attaining a CR. Case Presentation: Case 1 was a 58-year-old man who underwent laparoscopic ileocecal resection for cecum cancer with multiple metastases to the lungs in 2011. We performed treatment with mFOLFOX6 and bevacizumab chemotherapy in August 2011. After 11 courses, computed tomography (CT) revealed a CR to chemotherapy in February 2012. He has remained disease-free for 5 years and 3 months. Case 2 was a 70-year-old woman who underwent laparoscopic ileocecal resection for cecum cancer in August 2010. Recurrence of multiple metastases to both lungs was detected in November 2010. We started treatment with XELOX and bevacizumab chemotherapy in January 2011. In January 2011, CT after 14 courses revealed disappearance of the lung lesions, thereby indicating a CR. She has remained disease-free for 5 years and 4 months. Conclusion: We encountered 2 patients with CRC with lung metastases who were treated with chemotherapy leading to a CR. Cases resulting in such a desirable outcome are extremely rare. PMID- 30283318 TI - Herniated Proximal Marker of the Stent into the Meningohypophyseal Trunk after Stent-Assisted Coil Embolization for Intracranial Aneurysms. AB - The SolitaireTM AB Neurovascular Remodeling Device (ev3, Irvine, CA, USA) is used to retain coils within an aneurysm, reducing the risk of embolic complications from coil herniation into the parent artery. Stents are deployed after confirming the optimal position of the stent markers across the aneurysm to avoid entry into perforators or branching arteries. Stent marker position is very important to prevent perforating or branching artery infarction. We performed stent-assisted coil embolization using the Solitaire AB stent to treat 2 aneurysms simultaneously. After successful coil embolization, we detached the Solitaire stent in the usual manner. However, the proximal stent marker, which was located at the horizontal segment of the cavernous internal carotid artery, moved into the meningohypophyseal trunk and occluded it. Although the distal markers were positioned optimally, we did not expect the proximal marker to be in the position where it was located. Fortunately, cranial nerve dysfunctions and pituitary deficiency did not develop. It is important to prevent ischemic injury by occlusion of the perforators or branching vessels that can be caused by malpositioned stent markers. We consider where the proximal marker of the stent might be located after detachment. PMID- 30283319 TI - A Fatal Case of Herpes Simplex Encephalitis with Two False-Negative Polymerase Chain Reactions. AB - An 88-year-old man presented with a 1-month history of altered mental status and seizures. His electrographic and imaging findings were suggestive of herpes simplex encephalitis (HSE), for which he was empirically treated with acyclovir. He underwent two lumbar punctures 3 days apart; both cerebrospinal fluid analyses tested negative for herpes simplex virus (HSV) by polymerase chain reaction (PCR). These negative results and his continued deterioration after 9 days of acyclovir therapy prompted treatment with steroids for possible autoimmune encephalitis. Shortly after the change in management, the patient died from cardiac arrest. At autopsy, his brain showed both gross and microscopic evidence of encephalitis and was positive for HSV by immunohistochemistry. This fatal case of HSE emphasizes the limitations of HSV PCR and the importance of clinical suspicion in the diagnosis and management of this disease. PMID- 30283320 TI - Low-Frequency rTMS and Intensive Occupational Therapy Improve Upper Limb Motor Function and Cortical Reorganization Assessed by Functional Near-Infrared Spectroscopy in a Subacute Stroke Patient. AB - There is still no agreement on the most suitable time and modality for application of repetitive transcranial magnetic stimulation (rTMS) to improve motor recovery in subacute stroke patients. The underlying mechanism of motor recovery following low-frequency rTMS is considered to be modulation of the interhemispheric asymmetry. On the other hand, the cortical balance of brain activity during the acute to chronic phase of stroke is reported to be unstable. Therefore, we conducted this study to clarify the time course of the interhemispheric asymmetry and the effect of application of low-frequency rTMS combined with occupational therapy on motor recovery and cortical imbalance of brain activity in a subacute stroke patient. The interhemispheric asymmetry in this patient with new-onset subcortical cerebral infarction and upper limb hemiparesis was evaluated longitudinally using functional near-infrared spectroscopy with finger tasks. A nonlesional hemisphere-dominant activation pattern was observed on day 28 after onset. On day 56 after onset, a bilaterally eminent activation pattern was observed. Low-frequency rTMS was applied on day 109 after stroke onset when the cortical activity shifted to the nonlesional hemisphere. The treatment resulted in improvement in motor function of the affected upper limb and a shift in brain activation to the lesional hemisphere. Our report is the first to describe the therapeutic benefits of low-frequency rTMS as assessed by longitudinal neuroimaging for functional recovery and interhemispheric asymmetry in a subacute stroke patient. PMID- 30283321 TI - A Case of Nonalcoholic Marchiafava-Bignami Disease with Left-Right Differential Agraphia of Chinese Characters. AB - We report a 68-year-old right-handed female who was admitted to our hospital complaining chiefly of incontinence and decreased activity. Her brain images showed characteristics of Marchiafava-Bignami disease, such as symmetrical abnormal signals localized in the corpus callosum. The patient had no drinking habits. Her past medical history included total gastric resection to treat gastric cancer. On hospital admission she was markedly underweight. This appeared to be a rare case of Marchiafava-Bignami disease not attributable to heavy drinking and occurring in a state of malnutrition. Evaluation of callosal dissociation symptoms produced findings indicative of such symptoms. She showed a marked difficulty in writing dictated single words and short sentences in Japanese alphabetic characters, especially with her left hand. In contrast, writing dictated words in Chinese characters (also used in written Japanese) was affected in both hands, with different types of dysgraphia seen in the right and left hands. The agraphia in the left hand seen in this patient appears to have occurred as a result of the language faculty of the left hemisphere failing to be transmitted to the right brain, while agraphia in the right hand may have occurred as a result of spatial processing information in the right hemisphere failing to be transmitted to the left hemisphere. PMID- 30283322 TI - Effects of Long-Term Treatment with T-PEMF on Forearm Muscle Activation and Motor Function in Parkinson's Disease. AB - Bipolar pulsed electromagnetic stimulation applied to the brain (T-PEMF) is a non pharmacological treatment which has been shown to stimulate nerve growth, attenuate nerve abnormalities, and improve microcirculation. We report on a 62 year-old, medically well-treated man with idiopathic Parkinson's disease. He was treated with T-PEMF, 30 min per day for three 8-week periods separated by two 1 week breaks. The disease made his handwriting impossible to read mainly due to small letters and lack of fluency. Forearm EMG measured during standardized conditions showed an involuntary spiky EMG pattern with regular burst activity (on his left side) at baseline. The intervention normalized the handwriting and forearm EMG. The UPDRS-motor score decreased from 25 to 17, and UPDRS-II handwriting decreased from a pre-intervention value of 3 to 0 after the intervention. Finally, the patient reported improved fine motor function, less muscle stiffness, less muscle cramps and tingling, and less fatigue during the day in response to the T-PEMF treatment. The improved handwriting lasted for approximately 3 months after the treatment. Our results should be considered as preliminary, and large-scale, controlled studies are recommended to elucidate the therapeutic potential of long-term treatment with T-PEMF. PMID- 30283323 TI - An Autopsy Case of Edwardsiella tarda Meningoencephalitis. AB - A 62-year-old male with a history of alcohol abuse was admitted with a headache and rapidly progressing altered consciousness that led to coma over several hours. Blood and cerebrospinal fluid cultures were positive for Edwardsiella tarda. Despite prompt treatment initiation, the patient died on the third hospital day. Autopsy showed meningitis of the entire cerebrum with ventriculitis, and alcoholic fatty liver was observed. Clinicians should be cognizant of E. tarda meningoencephalitis, a rare presentation which can be associated with poor outcomes in patients with excessive alcohol consumption and alcoholic liver disease. PMID- 30283324 TI - A Case of Focal Choroidal Excavation Development Associated with Multiple Evanescent White Dot Syndrome. AB - Focal choroidal excavation (FCE) is described as an excavated lesion of the choroid that can be detected by optical coherence tomography (OCT). While the exact pathogenesis of FCE remains unclear, it has been proposed in some cases that there is an association with the inflammation in the outer retina. We present a case of FCE development that was detected by spectral domain OCT (SD OCT) and found to be associated with multiple evanescent white dot syndrome (MEWDS). A 40-year-old Japanese woman was diagnosed with MEWDS based on multiple white dots observed from the posterior pole to the midperiphery, along with yellow granularity in the fovea. SD-OCT revealed separation between the retinal pigment epithelium (RPE) and Bruch's membrane (BM) and discontinuations of the ellipsoid zone, RPE, and BM. At 4 weeks after onset, several of the white dots disappeared, the yellow granularity in the fovea became small, and we detected nonconforming choroidal excavation under the central fovea. The choroidal excavation gradually deepened and changed to a conforming pattern. These findings suggest that the degree of the impairment caused by inflammation and the plasticity of the BM and RPE complex may be associated with different types of acquired FCE. PMID- 30283325 TI - BrightOcular(r) Cosmetic Iris Implant: A Spectrum from Tolerability to Severe Morbidity. AB - Purpose: The BrightOcular(r) implants are the newest model of cosmetic iris devices that are currently advertised as safe. The previous generation known as NewColorIris(r) have had severe ocular side effects and were subsequently withdrawn from the market. There is little literature on the safety profile of BrightOcular(r) implants. Case Report: Herein we describe two cases with varying degrees of ocular tolerability. The first case had a normal ocular exam 1 year after implantation, whereas the second case had unilateral severe corneal edema requiring explantation of the iris device and Descemet membrane endothelial keratoplasty 9 months after bilateral implantation. Conclusions: These two cases attest to the unpredictability of the results of these cosmetic surgeries. Patients should be counseled about the vision-threatening complications of iris implants. PMID- 30283326 TI - A Case Report of Intravitreal Bevacizumab for Iris Metastasis of Small Cell Lung Carcinoma with Neovascular Glaucoma. AB - A 79-year-old man who had been diagnosed with small cell lung carcinoma (SCLC) complained of right ocular pain and blurred vision. His right intraocular pressure (IOP) was 30 mm Hg, and anterior chamber cells and multiple grayish white iris masses associated with peripheral anterior synechia (PAS) and neovascularization of the right iris were observed. We presumed that the iris masses were iris metastasis of SCLC. Despite therapy with topical eye drops and oral acetazolamide, the IOP was poorly controlled, so we injected intravitreal bevacizumab into his right eye for neovascular glaucoma. Neovascular glaucoma disappeared rapidly, but the IOP did not improve because of total PAS. To our knowledge, there is only one report of the use of intravitreal bevacizumab for SCLC metastasis in that eye and they reported that intravitreal injection resulted in successful short-term regression of presumed iris metastasis and improved control of secondary neovascular glaucoma, and the case had over one half PAS. The previous report and our results suggest that secondary neovascular glaucoma with iris metastasis may be controlled by early intravitreal bevacizumab injection. PMID- 30283327 TI - Case Series of Inappropriate Concentration of Intraocular Sulfur Hexafluoride. AB - Due to high complexity, vitreoretinal surgery presents a higher number of patient safety incidents compared with other ophthalmic procedures. Intraocular gases are one of the most useful adjuncts to vitrectomy and surprisingly, surgeons commonly admit to having occasional problems with incorrect gas concentration. The aim of this study is to present a consecutive case series of patients with improper concentration of sulfur hexafluoride (SF6) applied during vitrectomy. Three patients underwent 27-gauge vitrectomy and at the end of surgery inappropriate dilution of 100% SF6 was administered. It was attributed to a calculation error, change in the gas supplier, or increased partial pressure of SF6 before dilution. Postoperatively, due to IOP increase, two eyes required intravitreal gas-air exchange. Subsequently, cataract surgery was performed in one eye with concomitant vitrectomy and silicone oil tamponade due to retinal detachment. To prevent such complications, we suggest using intraocular gases with great care, training of ophthalmic personnel, and prompting manufacturers to provide SF6 in a prepared concentration of 20%.

PMID- 30283329 TI - Healthy Aging and Dementia: Two Roads Diverging in Midlife? AB - Dementia, particularly Alzheimer's disease (AD), is a growing pandemic that presents profound challenges to healthcare systems, families, and societies throughout the world. By 2050, the number of people living with dementia worldwide could almost triple, from 47 to 132 million, with associated costs rising to $3 trillion. To reduce the future incidence of dementia, there is an immediate need for interventions that target the disease process from its earliest stages. Research programs are increasingly starting to focus on midlife as a critical period for the beginning of AD-related pathology, yet the indicators of the incipient disease process in asymptomatic individuals remain poorly understood. We address this important knowledge gap by examining evidence for cognitive and structural brain changes that may differentiate, from midlife, healthy aging and pathological AD-related processes. This review crystallizes emerging trends for divergence between the two and highlights current limitations and opportunities for future research in this area. PMID- 30283330 TI - Clinical Heterogeneity Among LRRK2 Variants in Parkinson's Disease: A Meta Analysis. AB - Background: Parkinson's disease (PD) is one of the most common neurodegenerative diseases. Variants in the LRRK2 gene have been shown to be associated with PD. However, the clinical characteristics of LRRK2-related PD are heterogeneous. In our study, we performed a comprehensive pooled analysis of the association between specific LRRK2 variants and clinical features of PD. Methods: Articles from the Medline, Embase, and Cochrane databases were included in the meta analysis. Strict inclusion criteria were applied, and detailed information was extracted from the final original articles included. Revman 5.3 software was used for publication biases and pooled and sensitivity analyses. Results: In all, 66 studies having the clinical manifestations of PD patients with G2019S, G2385R, R1628P, and R1441G were included for the final analysis. The prominent clinical features of LRRK2-G2019S-related PD patients were female sex, higher rates of early-onset PD (EOPD), and family history (OR: 0.77 [male], 1.37, 2.62; p < 0.00001, 0.02, < 0.00001). PD patients with G2019S were more likely to have high scores of Schwab & England (MD: 1.49; p < 0.00001), low GDS scores, high UPSIT scores (MD: 0.43, 4.70; p = 0.01, < 0.00001), and good response to L-dopa (OR: 2.33; p < 0.0001). Further, G2019S carriers had higher LEDD (MD: 115.20; p < 0.00001) and were more likely to develop motor complications, such as dyskinesia and motor fluctuations (OR: 2.18, 2.02; p < 0.00001, 0.04) than non-carriers. G2385R carriers were more likely to have family history (OR: 2.10; p = 0.007) than non-G2385R carriers and lower H-Y and higher MMSE scores (MD: -0.13, 1.02; p = 0.02, 0.0007). G2385R carriers had higher LEDD and tended to develop motor complications, such as motor fluctuations (MD: 53.22, OR: 3.17; p = 0.01, < 0.00001) than non-carriers. Other clinical presentations did not feature G2019S or G2385R. We observed no distinct clinical features for R1628P or R1441G. Our subgroup analyses in different ethnic group for specific variant also presented with relevant clinical characteristics of PD patients. Conclusions: Clinical heterogeneity was observed among LRRK2-associated PD in different variants in total and in different ethnic groups, especially for G2019S and G2385R.

AB - Tardive dyskinesia (TD) is a movement disorder that may occur after extended use of antipsychotic medications. The etiopathophysiology is unclear; however, genetic factors play an important role. The Perlecan (HSPG2) gene was found to be significantly associated with TD in Japanese schizophrenia patients, and this association was subsequently replicated by an independent research group. To add to the evidence for this gene in TD, we conducted a meta-analysis specific to the relationship of HSPG2 rs2445142 with TD occurrence, while also adding our unpublished genotype data. Overall, we found a significant association of the G allele with TD occurrence (p = 0.0001); however, much of the effect appeared to originate from the discovery dataset. Nonetheless, most study samples exhibit the same trend of association with TD for the G allele. Our findings encourage further genetic and molecular studies of HSPG2 in TD. PMID- 30283333 TI - Prophylactic and Therapeutic Use of Strontium Ranelate Reduces the Progression of Experimental Osteoarthritis. AB - Introduction: Strontium ranelate (SrRan) has the potential to interfere in the progression of osteoarthritis (OA), multifactorial disease associated with mechanical problems and articular inflammatory changes. Objectives: This study aimed to test the effects of prophylactic and therapeutic use of SrRan on clinical parameters of pain, the inflammatory process, and degradation of the articular cartilage. Methods: This was an experimental study, using a model of knee OA induced by intra-articular injection of monoiodoacetate. Thirty Wistar rats were divided into five groups and treated as indicated: control, without intervention; prophylactic, received SrRan at a daily oral dose of 250 mg/kg for 28 days before OA induction; SrRan treatments, administered 250 or 500 mg/kg/day for 28 days after the induction; and model control, received saline solution after the induction. Behavioral tests (joint incapacity, mechanical hyperalgesia, tactile sensitivity, and forced ambulation), histological evaluation of articular cartilage, and determination of inflammatory cytokines in the synovial fluid (interleukin [IL]-6, IL-10, tumor necrosis factor [TNF]-alpha, and interferon [INF]-gamma) were performed. Results: Both prophylactic and therapeutic treatments improved the articular discomfort. A prophylactic dose of 500 mg/kg/day also improved mechanical hyperalgesia and the same dose was beneficial on tactile sensitivity. SrRan did not improve ambulation. Levels of IL-6, IL-10, TNF-alpha, and IFN-gamma in SrRan-treated groups with OA were not significantly different compared with those in the normal control animals. The histopathological evaluation showed less articular damage in the SrRan-treated and control groups compared to the saline-treated group. Conclusion: The prophylactic and therapeutic administration of SrRan was associated with improved behavioral patterns of pain, especially joint discomfort. SrRan administration mitigated histological changes in the articular cartilage and reduced the inflammatory process, which beneficially reduced the progression of OA in the experimental model studied. PMID- 30283334 TI - Bone Health and Natural Products- An Insight. AB - Bone metabolism involves a complex balance between matrix deposition, mineralization, and resorption. Numerous evidences have revealed that dietary components and phytoconstituents can influence these processes, through inhibition of bone resorption, thus exhibiting beneficial effects on the skeleton. Various traditional herbal formulae in ayurvedic and Chinese medicine have shown demonstrable benefits in pharmacological models of osteoporosis. The present review discusses normal bone metabolism and disorders caused by bone disruption, with particular reference to osteoporosis and current therapeutic treatment. Furthermore the effects of constituents from natural products on bone tissue are explained, with relevant evidences of efficacy in various experimental models. PMID- 30283336 TI - beta-Arrestin 2 Promotes Hepatocyte Apoptosis by Inhibiting Akt Pathway in Alcoholic Liver Disease. AB - Alcoholic liver disease (ALD) is a complex process that includes a wide range of hepatic lesions, from steatosis to cirrhosis, and even hepatocellular carcinoma (HCC). Accumulating evidence shows that the cytotoxic effects of ethanol metabolism lead to cell apoptosis and necrosis in ALD. Recently, several studies revealed that multifunctional protein beta-arrestin 2 (Arrb2) modulated cell apoptosis in liver fibrosis and HCC, but its role in ALD has not been fully understood. The aim of this study is to explore the function and underlying mechanism of Arrb2 in hepatocyte survival and apoptosis in ALD. In our study, the primary hepatocytes were isolated from the livers of C57BL/6 mice fed EtOH containing diet, it showed an increased level of Arrb2. EtOH also significantly up-regulated Arrb2 production in AML-12 cells in vitro. Furthermore, TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling) and FCM results demonstrated that knockdown of Arrb2 could inhibit hepatocyte apoptosis induced by EtOH in vivo and vitro while over-expression of Arrb2 induced apoptosis in ALD. In addition, western blot results revealed that Arrb2 remarkably suppressed the Akt signaling. Taken together, our data suggested that Arrb2 may serve as a potential therapeutic target for ALD by promoting hepatocyte apoptosis via Akt suppression. PMID- 30283337 TI - The Modulatory Role of CYP3A4 in Dictamnine-Induced Hepatotoxicity. AB - Dictamni Cortex (DC) has been reported to be associated with acute hepatitis in clinic and may lead to a selective sub-chronic hepatotoxicity in rats. Nevertheless, the potent toxic ingredient and the underlying mechanism remain unknown. Dictamnine (DTN), the main alkaloid from DC, possesses a furan ring which was suspected of being responsible for hepatotoxicity via metabolic activation primarily by CYP3A4. Herein, the present study aimed to evaluate the role of CYP3A4 in DTN-induced liver injury. The in vitro results showed that the EC50 values in primary human hepatocytes (PHH), L02, HepG2 and NIH3T3 cells were correlated with the CYP3A4 expression levels in corresponding cells. Furthermore, the toxicity was increased in CYP3A4-induced PHH by rifampicin, and CYP3A4 over expressed (OE) HepG2 and L02 cells. Contrarily, the cytotoxicity was decreased in CYP3A4-inhibited PHH and CYP3A4 OE HepG2 and L02 cells inhibited by ketoconazole (KTZ). In addition, the hepatotoxicity of DTN in enzyme induction/inhibition mice was further investigated in the aspects of biochemistry, histopathology, and pharmacokinetics. Administration of DTN in combination with KTZ resulted in attenuated liver injury, including lower alanine transaminase and aspartate transaminase activities and greater AUC and C max of serum DTN, whereas, pretreatment with dexamethasone aggravated the injury. Collectively, our findings illustrated that DTN-induced hepatotoxicity correlated well with the expression of CYP3A4, namely inhibition of CYP3A4 alleviated the toxicity both in vitro and in vivo, and induction aggravated the toxicity effects. PMID- 30283339 TI - Urolithin A Inhibits the Catabolic Effect of TNFalpha on Nucleus Pulposus Cell and Alleviates Intervertebral Disc Degeneration in vivo. AB - Low back pain (LBP) is a common worldwide disease that causes an enormous social economic burden. Intervertebral disc degeneration (IDD) is considered as a major cause of LBP. The process of IDD is complicated and involves both inflammation and senescence. The production of pro-inflammatory cytokines, including tumor necrosis factor (TNF)alpha and interleukin (IL)-1beta, is increased in the degenerating intervertebral disc, inducing extracellular matrix degradation. Urolithin A (UA) is a metabolite compound resulting from the degradation of ellagitannins by gut bacteria. UA has been reported to be useful for the treatment of diseases associated with inflammation, senescence, and oxidative damage. Therefore, we hypothesized that UA may be an effective treatment for IDD. This study examined the effects of UA on IDD in vitro and in vivo and explored their underlying mechanisms. Our findings indicated that UA could attenuate cellular senescence induced by hydrogen peroxide in nucleus pulposus cells. UA treatment decreased TNFalpha-induced matrix metalloproteinase production and the loss of collagen II. At the molecular level, UA considerably blocked the phosphorylation of the extracellular signal-regulated kinase, c-JUN N-terminal kinase, and Akt pathways. In vivo study illustrated that UA treatment could ameliorate IDD in a needle-punctured rat tail model, which was evaluated by X-ray imaging, magnetic resonance imaging, and histological analysis. Thus, the results of our study revealed that UA may be a useful therapeutic agent for the treatment of IDD. PMID- 30283338 TI - Association of N6AMT1 rs2254638 Polymorphism With Clopidogrel Response in Chinese Patients With Coronary Artery Disease. AB - Dual antiplatelet treatment with aspirin and clopidogrel is the standard therapy for patients undergoing percutaneous coronary intervention (PCI). However, a portion of patients suffer from clopidogrel resistance (CR) and consequently with recurrence of cardiovascular events. Genetic factors such as loss-of-function variants of CYP2C19 contribute a lot to CR. Recently, the N-6-adenine-specific DNA methyltransferase 1 (N6AMT1) rs2254638 polymorphism is reported to be associated with clopidogrel response. To validate the association between N6AMT1 rs2254638 polymorphism and clopidogrel response, 435 Chinese CAD patients receiving aspirin and clopidogrel were recruited. N6AMT1 rs2254638 and CYP2C19 * 2/ * 3 polymorphisms were genotyped. Platelet reaction index (PRI) was measured by VASP-phosphorylation assay after treated with a 300 mg loading dose (LD) clopidogrel or 75 mg daily maintenance dose (MD) clopidogrel for at least 5 days. There was a significant difference in PRI between LD cohort and MD cohort. Carriers of CYP2C19 * 2 allele showed significantly increased PRI in the entire cohort and in respective of the MD and LD cohorts (p < 0.001, p = 0.003, p < 0.001, respectively). However, carriers of CYP2C19 * 3 allele exhibited significantly higher PRI only in the entire cohort and LD cohort (p = 0.023, p = 0.023 respectively). PRI value was significantly higher in CYP2C19 PM genotyped patients as compared with those carrying the IM genotypes and EM genotype (p < 0.001). Besides, carriers of the rs2254638 C allele showed significantly higher PRI in entire cohort and in the LD cohort (p = 0.023, p = 0.008, respectively). When the patients were grouped into clopidogrel resistance (CR) and non clopidogrel resistance (non-CR) groups, CYP2C19 * 2 was associated with increased risk of CR in the entire cohort, the LD cohort and the MD cohort (p < 0.001, p < 0.001, and p = 0.019, respectively). Carriers of the rs2254638 C allele also showed increased risk of CR in the entire cohort and the LD cohort (p = 0.024, and p = 0.028, respectively). N6AMT1 rs2254638 remained as a strong predictor for CR (TC vs. TT: OR = 1.880, 95% CI = 1.099-3.216,p = 0.021; CC vs. TT: OR = 1.930, 95% CI = 1.056-3.527, p = 0.032; TC + CC vs. TT: OR = 1.846, 95%CI = 1.126-3.026, p = 0.015) after adjustment for confounding factors. Our study confirmed the influence of CYP2C19 *2 and rs2254638 polymorphisms on clopidogrel resistance in Chinese CAD patients. Both CYP2C19 * 2 and N6AMT1 rs2254638 polymorphism may serve as independent biomarkers to predict CR. PMID- 30283340 TI - Overexpression of MYCT1 Inhibits Proliferation and Induces Apoptosis in Human Acute Myeloid Leukemia HL-60 and KG-1a Cells in vitro and in vivo. AB - MYC target 1 (MYCT1), a direct target gene of c-Myc, is a novel candidate tumor suppressor gene first cloned from laryngeal squamous cell carcinoma. The downregulation of MYCT1 has been reported to be associated with carcinogenesis. However, the role of MYCT1 in the development and progress of acute myeloid leukemia (AML) remains unknown and requires further investigation. In this study, we first found that the expression level of MYCT1 was significantly lower in the bone marrow (BM) derived from AML patients than that from healthy individuals. The low expression of MYCT1 in AML BM may be due to the hypermethylation in its promoter. MYCT1 expression was strongly associated with French-American-British classifications of AML. The low expression level of MYCT1 was more often observed in patients of M1, M5 and M6 types. In vitro, lentiviral particles carrying the complete CDS of MYCT1 gene were used to mediate the forced overexpression of MYCT1 in two AML cell lines, HL-60 and KG-1a. MYCT1 overexpression significantly inhibited cell proliferation, arrested cell cycle at G0/G1 phase, and downregulated the expression of cyclins D and E. Moreover, MYCT1 overexpression triggered apoptosis in AML cells, which was accompanied by enhanced cleavage of caspase-3 and -9, upregulated expression of B-cell lymphoma 2 (Bcl-2)-associated X protein (Bax), and downregulated Bcl-2. Finally, in BALB/c nude mice bearing xenograft tumors generated by HL-60 and KG-1a cells, we noted that the intratumoral injection of MYCT1 lentivirus repressed tumor growth and led to massive apoptosis. In summary, our results reveal that MYCT1's promoter is hypermethylated and its expression is downregulated in the BM of AML patients. MYCT1 plays a tumor-suppressive role, and it may serve as a promising target for the genetic therapeutic strategy in treating AML. PMID- 30283335 TI - Development of an AmpliSeqTM Panel for Next-Generation Sequencing of a Set of Genetic Predictors of Persisting Pain. AB - Background: Many gene variants modulate the individual perception of pain and possibly also its persistence. The limited selection of single functional variants is increasingly being replaced by analyses of the full coding and regulatory sequences of pain-relevant genes accessible by means of next generation sequencing (NGS). Methods: An NGS panel was created for a set of 77 human genes selected following different lines of evidence supporting their role in persisting pain. To address the role of these candidate genes, we established a sequencing assay based on a custom AmpliSeqTM panel to assess the exomic sequences in 72 subjects of Caucasian ethnicity. To identify the systems biology of the genes, the biological functions associated with these genes were assessed by means of a computational over-representation analysis. Results: Sequencing generated a median of 2.85 ? 106 reads per run with a mean depth close to 200 reads, mean read length of 205 called bases and an average chip loading of 71%. A total of 3,185 genetic variants were called. A computational functional genomics analysis indicated that the proposed NGS gene panel covers biological processes identified previously as characterizing the functional genomics of persisting pain. Conclusion: Results of the NGS assay suggested that the produced nucleotide sequences are comparable to those earned with the classical Sanger sequencing technique. The assay is applicable for small to large-scale experimental setups to target the accessing of information about any nucleotide within the addressed genes in a study cohort. PMID- 30283341 TI - Electrical Spinal Stimulation, and Imagining of Lower Limb Movements to Modulate Brain-Spinal Connectomes That Control Locomotor-Like Behavior. AB - Neuronal control of stepping movement in healthy human is based on integration between brain, spinal neuronal networks, and sensory signals. It is generally recognized that there are continuously occurring adjustments in the physiological states of supraspinal centers during all routines movements. For example, visual as well as all other sources of information regarding the subject's environment. These multimodal inputs to the brain normally play an important role in providing a feedforward source of control. We propose that the brain routinely uses these continuously updated assessments of the environment to provide additional feedforward messages to the spinal networks, which provides a synergistic feedforwardness for the brain and spinal cord. We tested this hypothesis in 8 non injured individuals placed in gravity neutral position with the lower limbs extended beyond the edge of the table, but supported vertically, to facilitate rhythmic stepping. The experiment was performed while visualizing on the monitor a stick figure mimicking bilateral stepping or being motionless. Non-invasive electrical stimulation was used to neuromodulate a wide range of excitabilities of the lumbosacral spinal segments that would trigger rhythmic stepping movements. We observed that at the same intensity level of transcutaneous electrical spinal cord stimulation (tSCS), the presence or absence of visualizing a stepping-like movement of a stick figure immediately initiated or terminated the tSCS-induced rhythmic stepping motion, respectively. We also demonstrated that during both voluntary and imagined stepping, the motor potentials in leg muscles were facilitated when evoked cortically, using transcranial magnetic stimulation (TMS), and inhibited when evoked spinally, using tSCS. These data suggest that the ongoing assessment of the environment within the supraspinal centers that play a role in planning a movement can routinely modulate the physiological state of spinal networks that further facilitates a synergistic neuromodulation of the brain and spinal cord in preparing for movements. PMID- 30283342 TI - Theoretical Explorations Generate New Hypotheses About the Role of the Cartilage Endplate in Early Intervertebral Disk Degeneration. AB - Altered cell nutrition in the intervertebral disk (IVD) is considered a main cause for disk degeneration (DD). The cartilage endplate (CEP) provides a major path for the diffusion of nutrients from the peripheral vasculature to the IVD nucleus pulposus (NP). In DD, sclerosis of the adjacent bony endplate is suggested to be responsible for decreased diffusion and disk cell nutrition. Yet, experimental evidence does not support this hypothesis. Hence, we evaluated how moderate CEP composition changes related to tissue degeneration can affect disk nutrition and cell viability. A novel composition-based permeability formulation was developed for the CEP, calibrated, validated, and used in a mechano-transport finite element IVD model. Fixed solute concentrations were applied at the outer surface of the annulus and the CEP, and three cycles of daily mechanical load were simulated. The CEP model indicated that CEP permeability increases with the degeneration/aging of the tissue, in accordance with recent measurements reported in the literature. Additionally, our results showed that CEP degeneration might be responsible for mechanical load-induced NP dehydration, which locally affects oxygen and lactate levels, and reduced glucose concentration by 16% in the NP annulus transition zone. Remarkably, CEP degeneration was a condition sine-qua non to provoke cell starvation and death, while simulating the effect of extracellular matrix depletion in DD. This theoretical study cast doubts about the paradigm that CEP calcification is needed to provoke cell starvation, and suggests an alternative path for DD whereby the early degradation of the CEP plays a key role. PMID- 30283331 TI - Intracrine Regulation of Estrogen and Other Sex Steroid Levels in Endometrium and Non-gynecological Tissues; Pathology, Physiology, and Drug Discovery. AB - Our understanding of the intracrine (or local) regulation of estrogen and other steroid synthesis and degradation expanded in the last decades, also thanks to recent technological advances in chromatography mass-spectrometry. Estrogen responsive tissues and organs are not passive receivers of the pool of steroids present in the blood but they can actively modify the intra-tissue steroid concentrations. This allows fine-tuning the exposure of responsive tissues and organs to estrogens and other steroids in order to best respond to the physiological needs of each specific organ. Deviations in such intracrine control can lead to unbalanced steroid hormone exposure and disturbances. Through a systematic bibliographic search on the expression of the intracrine enzymes in various tissues, this review gives an up-to-date view of the intracrine estrogen metabolisms, and to a lesser extent that of progestogens and androgens, in the lower female genital tract, including the physiological control of endometrial functions, receptivity, menopausal status and related pathological conditions. An overview of the intracrine regulation in extra gynecological tissues such as the lungs, gastrointestinal tract, brain, colon and bone is given. Current therapeutic approaches aimed at interfering with these metabolisms and future perspectives are discussed. PMID- 30283344 TI - Impact of Intrauterine Growth Restriction on Cognitive and Motor Development at 2 Years of Age. AB - Intrauterine growth restriction (IUGR), which is already known to be a risk factor for pathological intrauterine development, perinatal mortality, and morbidity, is now also assumed to cause both physical and cognitive alterations in later child development. In the current study, effects of IUGR on infantile brain function were investigated during the fetal period and in a follow-up developmental assessment during early childhood. During the fetal period, visual and auditory event-related responses (VER and AER) were recorded using fetal magnetoencephalography (fMEG). VER latencies were analyzed in 73 fetuses (14 IUGR fetuses) while AER latencies were analyzed in 66 fetuses (11 IUGR fetuses). Bayley Scales of Infant Development, Second Edition (BSID-II) were used to assess the developmental status of the infants at the age of 24 months. The Mental Development Index (MDI) was available from 66 children (8 IUGR fetuses) and the Psychomotor Development Index (PDI) from 63 children (7 IUGR fetuses). Latencies to visual stimulation were more delayed in IUGR than in small for gestational age (SGA) or appropriate for gestational age (AGA) fetuses, albeit not to any significant extent (p = 0.282). The MDI in former IUGR infants was significantly lower (p = 0.044) than in former SGA and AGA infants. However, IUGR had no impact on PDI (p = 0.213). These findings support the hypothesis that IUGR may constitute a risk factor for neurodevelopmental delay. Further investigation of the possible underlying mechanisms, as well as continued long-term developmental research, is therefore necessary. PMID- 30283343 TI - The Role of Calcitonin Gene Related Peptide (CGRP) in Neurogenic Vasodilation and Its Cardioprotective Effects. AB - Calcitonin gene-related peptide (CGRP) is a highly potent vasoactive peptide released from sensory nerves, which is now proposed to have protective effects in several cardiovascular diseases. The major alpha-form is produced from alternate splicing and processing of the calcitonin gene. The CGRP receptor is a complex composed of calcitonin like receptor (CLR) and a single transmembrane protein, RAMP1. CGRP is a potent vasodilator and proposed to have protective effects in several cardiovascular diseases. CGRP has a proven role in migraine and selective antagonists and antibodies are now reaching the clinic for treatment of migraine. These clinical trials with antagonists and antibodies indicate that CGRP does not play an obvious role in the physiological control of human blood pressure. This review discusses the vasodilator and hypotensive effects of CGRP and the role of CGRP in mediating cardioprotective effects in various cardiovascular models and disorders. In models of hypertension, CGRP protects against the onset and progression of hypertensive states by potentially counteracting against the pro hypertensive systems such as the renin-angiotensin-aldosterone system (RAAS) and the sympathetic system. With regards to its cardioprotective effects in conditions such as heart failure and ischaemia, CGRP-containing nerves innervate throughout cardiac tissue and the vasculature, where evidence shows this peptide alleviates various aspects of their pathophysiology, including cardiac hypertrophy, reperfusion injury, cardiac inflammation, and apoptosis. Hence, CGRP has been suggested as a cardioprotective, endogenous mediator released under stress to help preserve cardiovascular function. With the recent developments of various CGRP-targeted pharmacotherapies, in the form of CGRP antibodies/antagonists as well as a CGRP analog, this review provides a summary and a discussion of the most recent basic science and clinical findings, initiating a discussion on the future of CGRP as a novel target in various cardiovascular diseases. PMID- 30283346 TI - Carotid Body Type-I Cells Under Chronic Sustained Hypoxia: Focus on Metabolism and Membrane Excitability. AB - Chronic sustained hypoxia (CSH) evokes ventilatory acclimatization characterized by a progressive hyperventilation due to a potentiation of the carotid body (CB) chemosensory response to hypoxia. The transduction of the hypoxic stimulus in the CB begins with the inhibition of K+ currents in the chemosensory (type-I) cells, which in turn leads to membrane depolarization, Ca2+ entry and the subsequent release of one- or more-excitatory neurotransmitters. Several studies have shown that CSH modifies both the level of transmitters and chemoreceptor cell metabolism within the CB. Most of these studies have been focused on the role played by such putative transmitters and modulators of CB chemoreception, but less is known about the effect of CSH on metabolism and membrane excitability of type-I cells. In this mini-review, we will examine the effects of CSH on the ion channels activity and excitability of type-I cell, with a particular focus on the effects of CSH on the TASK-like background K+ channel. We propose that changes on TASK-like channel activity induced by CSH may contribute to explain the potentiation of CB chemosensory activity. PMID- 30283345 TI - The Role of Neuropeptide Y in Cardiovascular Health and Disease. AB - Neuropeptide Y (NPY) is an abundant sympathetic co-transmitter, widely found in the central and peripheral nervous systems and with diverse roles in multiple physiological processes. In the cardiovascular system it is found in neurons supplying the vasculature, cardiomyocytes and endocardium, and is involved in physiological processes including vasoconstriction, cardiac remodeling, and angiogenesis. It is increasingly also implicated in cardiovascular disease pathogenesis, including hypertension, atherosclerosis, ischemia/infarction, arrhythmia, and heart failure. This review will focus on the physiological and pathogenic role of NPY in the cardiovascular system. After summarizing the NPY receptors which predominantly mediate cardiovascular actions, along with their signaling pathways, individual disease processes will be considered. A thorough understanding of these roles may allow therapeutic targeting of NPY and its receptors. PMID- 30283348 TI - Energy Expenditure as a Function of Activity Level After Spinal Cord Injury: The Need for Tetraplegia-Specific Energy Balance Guidelines. AB - The World Health Organization recognizes obesity as a global and increasing problem for the general population. Because of their reduced physical functioning, people with spinal cord injury (SCI) face additional challenges for maintaining an appropriate whole body energy balance, and the majority with SCI are overweight or obese. SCI also reduces exercise capacity, particularly in those with higher-level injury (tetraplegia). Tetraplegia-specific caloric energy expenditure (EE) data is scarce. Therefore, we measured resting and exercise based energy expenditure in participants with tetraplegia and explored the accuracy of general population-based energy use predictors. Body composition and resting energy expenditure (REE) were measured in 25 adults with tetraplegia (C4/5 to C8) and in a sex-age-height matched group. Oxygen uptake, carbon dioxide production, heart rate, perceived exertion, and exercise intensity were also measured in 125 steady state exercise trials. Those with motor-complete tetraplegia, but not controls, had measured REE lower than predicted (mean = 22% less, p < 0.0001). REE was also lower than controls when expressed per kilogram of lean mass. Nine had REE below 1200 kcal/day. We developed a graphic compendium of steady state EE during arm ergometry, wheeling, and hand-cycling. This compendium is in a format that can be used by persons with tetraplegia for exercise prescription (calories, at known absolute intensities). EE was low (55 450 kcal/h) at the intensities participants with tetraplegia were capable of maintaining. If people with tetraplegia followed SCI-specific activity guidelines (220 min/week) at the median intensities we measured, they would expend 563-1031 kcal/week. Participants with tetraplegia would therefore require significant time (4 to over 20 h) to meet a weekly 2000 kcal exercise target. We estimated total daily EE for a range of activity levels in tetraplegia and compared them to predicted values for the general population. Our analysis indicated that the EE values for sedentary through moderate levels of activity in tetraplegia fall well below predicted sedentary levels of activity for the general population. These findings help explain sub-optimal responses to exercise interventions after tetraplegia, and support the need to develop tetraplegia-specific energy-balance guidelines that reflects their unique EE situation. PMID- 30283349 TI - Effects of 3 Weeks of Oral Low-Dose Cobalt on Hemoglobin Mass and Aerobic Performance. AB - Introduction: Cobalt ions (Co2+) stabilize HIFalpha and increase endogenous erythropoietin (EPO) production creating the possibility that Co2+ supplements (CoSupp) may be used as performance enhancing substances. The aim of this study was to determine the effects of a small oral dosage of CoSupp on hemoglobin mass (Hbmass) and performance with the objective of providing the basis for establishing upper threshold limits of urine [Co2+] to detect CoSupp misuse in sport. Methods: Twenty-four male subjects participated in a double-blind placebo controlled study. Sixteen received an oral dose of 5 mg of ionized Co2+ per day for 3 weeks, and eight served as controls. Blood and urine samples were taken before the study, during the study and up to 3 weeks after CoSupp. Hbmass was determined by the CO-rebreathing method at regular time intervals, and VO2max was determined before and after the CoSupp administration period. Results: In the Co2+ group, Hbmass increased by 2.0 +/- 2.1% (p < 0.001) while all the other analyzed hematological parameters did not show significant interactions of time and treatment. Hemoglobin concentration ([Hb]) and hematocrit (Hct) tended to increase (p = 0.16, p = 0.1) and also [EPO] showed a similar trend (baseline: 9.5 +/- 3.0, after 2 weeks: 12.4 +/- 5.2 mU/ml). While mean VO2max did not change, there was a trend for a positive relationship between changes in Hbmass and changes in VO2max immediately after CoSupp (r = 0.40, p = 0.11). Urine [Co2+] increased from 0.4 +/- 0.3 to 471.4 +/- 384.1 ng/ml (p < 0.01) and remained significantly elevated until 2 weeks after cessation. Conclusion: An oral Co2+ dosage of 5 mg/day for 3 weeks effectively increases Hbmass with a tendency to increase hemoglobin concentration ([Hb]) and hematocrit (Hct). Because urine Co2+ concentration remains increased for 2 weeks after cessation, upper limit threshold values for monitoring CoSupp can be established. PMID- 30283347 TI - Fatigue in Chronic Respiratory Diseases: Theoretical Framework and Implications For Real-Life Performance and Rehabilitation. AB - Fatigue is a primary disabling symptom in chronic respiratory diseases (CRD) with major clinical implications. However, fatigue is not yet sufficiently explored and is still poorly understood in CRD, making this symptom underdiagnosed and undertreated in these populations. Fatigue is a dynamic phenomenon, particularly in such evolving diseases punctuated by acute events which can, alone or in combination, modulate the degree of fatigue experienced by the patients. This review supports a comprehensive inter-disciplinary approach of CRD-related fatigue and emphasizes the need to consider both its performance and perceived components. Most studies in CRD evaluated perceived fatigue as a trait characteristic using multidimensional scales, providing precious information about its prevalence and clinical impact. However, these scales are not adapted to understand the complex dynamics of fatigue in real-life settings and should be augmented with ecological assessment of fatigue. The state level of fatigue must also be considered during physical tasks as severe fatigue can emerge rapidly during exercise. CRD patients exhibit alterations in both peripheral and central nervous systems and these abnormalities can be exacerbated during exercise. Laboratory tests are necessary to provide mechanistic insights into how and why fatigue develops during exercise in CRD. A better knowledge of the neurophysiological mechanisms underlying perceived and performance fatigability and their influence on real-life performance will enable the development of new individualized countermeasures. This review aims first to shed light on the terminology of fatigue and then critically considers the contemporary models of fatigue and their relevance in the particular context of CRD. This article then briefly reports the prevalence and clinical consequences of fatigue in CRD and discusses the strengths and weaknesses of various fatigue scales. This review also provides several arguments to select the ideal test of performance fatigability in CRD and to translate the mechanistic laboratory findings into the clinical practice and real-world performance. Finally, this article discusses the dose-response relationship to training and the feasibility and validity of using the fatigue produced during exercise training sessions in CRD to optimize exercise training efficiency. Methodological concerns, examples of applications in selected diseases and avenues for future research are also provided. PMID- 30283350 TI - Aged Nicotinamide Riboside Kinase 2 Deficient Mice Present an Altered Response to Endurance Exercise Training. AB - Background: Skeletal muscle aging is marked by the development of a sarcopenic phenotype, a global decline of muscle energetic capacities, and an intolerance to exercise. Among the metabolic disorders involved in this syndrome, NAD metabolism was shown to be altered in skeletalmuscle, with an important role for the NAMPT enzyme recycling the nicotinamide precursor. An alternative pathway for NAD biosynthesis has been described for the nicotinamide riboside vitamin B3 precursor used by the NMRK kinases, including the striated muscle-specific NMRK2. Aim: With this study, our goal is to explore the ability of 16-month-old Nmrk2 -/ mice to perform endurance exercise and study the consequences on muscle adaptation to exercise. Methods: 10 control and 6 Nmrk2 -/- mice were used and randomly assigned to sedentary and treadmill endurance training groups. After 9 weeks of training, heart and skeletal muscle samples were harvested and used for gene expression analysis, NAD levels measurements and immunohistochemistry staining. Results: Endurance training triggered a reduction in the expression of Cpt1b and AcadL genes involved in fatty acid catabolism in the heart of Nmrk2 -/- mice, not in control mice. NAD levels were not altered in heart or skeletal muscle, nor at baseline neither after exercise training in any group. Myh7 gene encoding for the slow MHC-I was more strongly induced by exercise in Nmrk2 -/- mice than in controls. Moreover, IL-15 expression levels is higher in Nmrk2 -/- mice skeletal muscle at baseline compared to controls. No fiber type switch was observed in plantaris after exercise, but fast fibers diameter was reduced in aged control mice, not in Nmrk2 -/- mice. No fiber type switch or diameter modification was observed in soleus muscle. Conclusion: In this study, we demonstrated for the first time a phenotype in old Nmrk2 -/- mice in response to endurance exercise training. Although NMRK2 seems to be predominantly dispensable to maintain global NAD levels in heart and skeletal muscle, we demonstrated a maladaptive metabolic response to exercise in cardiac and skeletal muscle, showing that NMRK2 has a specific and restricted role in NAD signaling compared to the NAMPT pathway. PMID- 30283351 TI - S100A4 as a Target of the E3-Ligase Asb2beta and Its Effect on Engineered Heart Tissue. AB - Background: S100A4 has recently emerged as an important player in cardiac disease, affecting phenotype development in animal models of myocardial infarction and pathological cardiac hypertrophy, albeit it is unclear whether S100A4 exerts a detrimental or beneficial function. The goal of the current study was to analyze S100A4 expression in models of cardiac pathology, investigate its degradation by the ubiquitin-proteasome system (UPS), and furthermore examine the functional effects of S100A4 levels in a 3D model of engineered heart tissue (EHT). Methods and Results: S100A4 mRNA and protein levels were analyzed in different models of cardiac pathology via quantitative RT-PCR and Western blot, showing a higher S100A4 steady-state protein concentration in hearts of Mybpc3 knock-in (KI) hypertrophic cardiomyopathy (HCM) mice. COS-7 cells co-transfected with plasmids encoding mutant (MUT) Asb2beta lacking the E3 ligase activity in combination with V5-tagged S100A4 plasmid presented higher S100A4-V5 protein steady-state concentrations than cells co-transfected with the Asb2beta wild type (WT) plasmid. This effect was blunted by treatment with the specific proteasome inhibitor epoxomicin. Adeno-associated virus serotype 6 (AAV6)-mediated S100A4 overexpression in a 3D model of EHT did not affect contractile parameters. Immunofluorescence analysis showed a cytosolic and partly nuclear expression pattern of S100A4. Gene expression analysis in EHTs overexpressing S100A4-V5 showed markedly lower steady-state concentrations of genes involved in cardiac fibrosis and pathological cardiac hypertrophy. Conclusion: We showed that S100A4 protein level is higher in cardiac tissue of Mybpc3-KI HCM mice probably as a result of a lower degradation by the E3 ligase Asb2beta. While an overexpression of S100A4 did not alter contractile parameters in EHTs, downstream gene expression analysis points toward modulation of signaling cascades involved in fibrosis and hypertrophy. PMID- 30283352 TI - Quantification of Biventricular Strains in Heart Failure With Preserved Ejection Fraction Patient Using Hyperelastic Warping Method. AB - Heart failure (HF) imposes a major global health care burden on society and suffering on the individual. About 50% of HF patients have preserved ejection fraction (HFpEF). More intricate and comprehensive measurement-focused imaging of multiple strain components may aid in the diagnosis and elucidation of this disease. Here, we describe the development of a semi-automated hyperelastic warping method for rapid comprehensive assessment of biventricular circumferential, longitudinal, and radial strains that is physiological meaningful and reproducible. We recruited and performed cardiac magnetic resonance (CMR) imaging on 30 subjects [10 HFpEF, 10 HF with reduced ejection fraction patients (HFrEF) and 10 healthy controls]. In each subject, a three dimensional heart model including left ventricle (LV), right ventricle (RV), and septum was reconstructed from CMR images. The hyperelastic warping method was used to reference the segmented model with the target images and biventricular circumferential, longitudinal, and radial strain-time curves were obtained. The peak systolic strains are then measured and analyzed in this study. Intra- and inter-observer reproducibility of the biventricular peak systolic strains was excellent with all ICCs > 0.92. LV peak systolic circumferential, longitudinal, and radial strain, respectively, exhibited a progressive decrease in magnitude from healthy control->HFpEF->HFrEF: control (-15.5 +/- 1.90, -15.6 +/- 2.06, 41.4 +/- 12.2%); HFpEF (-9.37 +/- 3.23, -11.3 +/- 1.76, 22.8 +/- 13.1%); HFrEF (-4.75 +/- 2.74, -7.55 +/- 1.75, 10.8 +/- 4.61%). A similar progressive decrease in magnitude was observed for RV peak systolic circumferential, longitudinal and radial strain: control (-9.91 +/- 2.25, -14.5 +/- 2.63, 26.8 +/- 7.16%); HFpEF ( 7.38 +/- 3.17, -12.0 +/- 2.45, 21.5 +/- 10.0%); HFrEF (-5.92 +/- 3.13, -8.63 +/- 2.79, 15.2 +/- 6.33%). Furthermore, septum peak systolic circumferential, longitudinal, and radial strain magnitude decreased gradually from healthy control to HFrEF: control (-7.11 +/- 1.81, 16.3 +/- 3.23, 18.5 +/- 8.64%); HFpEF (-6.11 +/- 3.98, -13.4 +/- 3.02, 12.5 +/- 6.38%); HFrEF (-1.42 +/- 1.36, -8.99 +/ 2.96, 3.35 +/- 2.95%). The ROC analysis indicated LV peak systolic circumferential strain to be the most sensitive marker for differentiating HFpEF from healthy controls. Our results suggest that the hyperelastic warping method with the CMR-derived strains may reveal subtle impairment in HF biventricular mechanics, in particular despite a "normal" ventricular ejection fraction in HFpEF. PMID- 30283353 TI - TP63 Transcripts Play Opposite Roles in Chicken Skeletal Muscle Differentiation. AB - Tumor protein 63 (TP63) comprises multiple isoforms and plays an important role during embryonic development. It has been shown that TP63 knockdown inhibits myogenic differentiation, but which isoform is involved in the underlying myogenic regulation remains uncertain. Here, we found that two transcripts of TP63, namely, TAp63alpha and DeltaNp63alpha, are expressed in chicken skeletal muscle. These two transcripts have distinct expression patterns and opposite functions in skeletal muscle development. TAp63 has higher expression in skeletal muscle than in other tissues, and its expression is gradually upregulated during chicken primary myoblast differentiation. DeltaNp63 can be expressed in multiple tissues and exhibits stable expression during myoblast differentiation. TAp63alpha overexpression inhibits myoblast proliferation, induces cell cycle arrest, and enhances myoblast differentiation. However, although DeltaNp63alpha has no significant effect on cell proliferation, the overexpression of DeltaNp63alpha inhibits myoblast differentiation. Using isoform-specific overexpression assays following RNA-sequencing, we identified potential downstream genes of TAp63alpha and DeltaNp63alpha in myoblast. Bioinformatics analyses and experimental verification results showed that the differentially expressed genes (DEGs) between the TAp63alpha and control groups were enriched in the cell cycle pathway, whereas the DEGs between the DeltaNp63alpha and control groups were enriched in muscle system process, muscle contraction, and myopathy. These findings provide new insights into the function and expression of TP63 during skeletal muscle development, and indicate that one gene may play two opposite roles during a single cellular process. PMID- 30283354 TI - Partial Mechanical Unloading of the Heart Disrupts L-Type Calcium Channel and Beta-Adrenoceptor Signaling Microdomains. AB - Introduction: We investigated the effect of partial mechanical unloading (PMU) of the heart on the physiology of calcium and beta-adrenoceptor-cAMP (betaAR-cAMP) microdomains. Previous studies have investigated PMU using a model of heterotopic heart and lung transplantation (HTHAL). These studies have demonstrated that PMU disrupts the structure of cardiomyocytes and calcium handling. We sought to understand these processes by studying L-Type Calcium Channel (LTCC) activity and sub-type-specific betaAR-cAMP signaling within cardiomyocyte membrane microdomains. Method: We utilized an 8-week model of HTHAL, whereby the hearts of syngeneic Lewis rats were transplanted into the abdomens of randomly assigned cage mates. A pronounced atrophy was observed in hearts after HTHAL. Cardiomyocytes were isolated via enzymatic perfusion. We utilized Forster Resonance Energy Transfer (FRET) based cAMP-biosensors and scanning ion conductance microscopy (SICM) based methodologies to study localization of LTCC and betaAR-cAMP signaling. Results: beta2AR-cAMP responses measured by FRET in the cardiomyocyte cytosol were reduced by PMU (loaded 28.51 +/- 7.18% vs. unloaded 10.84 +/- 3.27% N,n 4/10-13 mean +/- SEM * p < 0.05). There was no effect of PMU on beta2AR-cAMP signaling in RII_Protein Kinase A domains. beta1AR cAMP was unaffected by PMU in either microdomain. Consistent with this SICM/FRET analysis demonstrated that beta2AR-cAMP was specifically reduced in t-tubules (TTs) after PMU (loaded TT 0.721 +/- 0.106% vs. loaded crest 0.104 +/- 0.062%, unloaded TT 0.112 +/- 0.072% vs. unloaded crest 0.219 +/- 0.084% N,n 5/6-9 mean +/- SEM ** p < 0.01, *** p < 0.001 vs. loaded TT). By comparison beta1AR-cAMP responses in either TT or sarcolemmal crests were unaffected by the PMU. LTCC occurrence and open probability (Po) were reduced by PMU (loaded TT Po 0.073 +/- 0.011% vs. loaded crest Po 0.027 +/- 0.006% N,n 5/18-26 mean +/- SEM * p < 0.05) (unloaded TT 0.0350 +/- 0.003% vs. unloaded crest Po 0.025 N,n 5/20-30 mean +/- SEM NS # p < 0.05 unloaded vs. loaded TT). We discovered that PMU had reduced the association between Caveolin-3, Junctophilin-2, and Cav1.2. Discussion: PMU suppresses' beta2AR-cAMP and LTCC activity. When activated, the signaling of beta2AR-cAMP and LTCC become more far-reaching after PMU. We suggest that a situation of 'suppression/decompartmentation' is elicited by the loss of refined cardiomyocyte structure following PMU. As PMU is a component of modern device therapy for heart failure this study has clinical ramifications and raises important questions for regenerative medicine. PMID- 30283355 TI - Modulation of Cardiac Alternans by Altered Sarcoplasmic Reticulum Calcium Release: A Simulation Study. AB - Background: Cardiac alternans is an important precursor to arrhythmia, facilitating formation of conduction block, and re-entry. Diseased hearts were observed to be particularly vulnerable to alternans, mainly in heart failure or after myocardial infarction. Alternans is typically linked to oscillation of calcium cycling, particularly in the sarcoplasmic reticulum (SR). While the role of SR calcium reuptake in alternans is well established, the role of altered calcium release by ryanodine receptors has not yet been studied extensively. At the same time, there is strong evidence that calcium release is abnormal in heart failure and other heart diseases, suggesting that these changes might play a pro alternans role. Aims: To demonstrate how changes to intracellular calcium release dynamics and magnitude affect alternans vulnerability. Methods: We used the state of-the-art Heijman-Rudy and O'Hara-Rudy computer models of ventricular myocyte, given their detailed representation of calcium handling and their previous utility in alternans research. We modified the models to obtain precise control over SR release dynamics and magnitude, allowing for the evaluation of these properties in alternans formation and suppression. Results: Shorter time to peak SR release and shorter release duration decrease alternans vulnerability by improved refilling of releasable calcium within junctional SR; conversely, slow release promotes alternans. Modulating the total amount of calcium released, we show that sufficiently increased calcium release may surprisingly prevent alternans via a mechanism linked to the functional depletion of junctional SR during release. We show that this mechanism underlies differences between "eye type" and "fork-type" alternans, which were observed in human in vivo and in silico. We also provide a detailed explanation of alternans formation in the given computer models, termed "sarcoplasmic reticulum calcium cycling refractoriness." The mechanism relies on the steep SR load-release relationship, combined with relatively limited rate of junctional SR refilling. Conclusion: Both altered dynamics and magnitude of SR calcium release modulate alternans vulnerability. In particular, slow dynamics of SR release, such as those observed in heart failure, promote alternans. Therefore, acceleration of intracellular calcium release, e.g., via synchronization of calcium sparks, may inhibit alternans in failing hearts and reduce arrhythmia occurrence. PMID- 30283357 TI - A Medal in the Olympics Runs in the Family: A Cohort Study of Performance Heritability in the Games History. AB - Introduction: Elite performance in sports is known to be influenced by heritable components, but the magnitude of such an influence has never been quantified. Hypothesis/Objectives: We hypothesized that having a former world-class champion in the family increases the chances of an athlete to repeat the achievement of her or his kinship. We aimed to measure the heritability of a medal in the Olympic Games (OG) among Olympians and to estimate the percentage of the genetic contribution to such a heritance. Study Design: Twin-family study of a retrospective cohort. Methods: All the 125,051 worldwide athletes that have participated in the OG between 1896 and 2012 were included. The expected probability to win a medal in the OG was defined as the frequency of medallists among Olympians without any blood kinship in the OG. This expected probability was compared with the probability to win a medal for Olympians having a kinship (grandparent, aunt/uncle, parent, or siblings) with a former Olympian that was a (1) non-medallist or (2) medallist. The heritability of the genetically determined phenotype (h2) was assessed by probandwise concordance rates among dizygotic (DZ) and monozygotic (MZ) twins (n = 90). Results: The expected probability to win a medal in the OG was 20.4%. No significant difference of medal probability was found in the subgroups of Olympians with a Non-medallist kinship, except among siblings for whom this probability was lower: 13.3% (95% CI 11.2-14.8). The medal probability was significantly greater among Olympians having a kinship with a former Olympic Medallist: 44.4% for niece/nephew (33.7 54.2); 43.4% for offspring (37.4-48.6); 64.8% for siblings (61.2-68.8); 75.5% for DZ twins (63.3-86.6); and 85.7% for MZ twins (63.6-96.9); with significantly greater concordance between MZ than DZ (p = 0.01) and h2 estimated at 20.5%. Conclusion: Having a kinship with a former Olympic medallist is associated with a greater probability for an Olympian to also become a medallist, the closer an athlete is genetically to such kinship the greater this probability. Once in the OG, the genetic contribution to win a medal is estimated to be 20.5%. PMID- 30283358 TI - FasL Modulates Expression of Mmp2 in Osteoblasts. AB - FasL is a well-known actor in the apoptotic pathways but recent reports have pointed to its important novel roles beyond cell death, as observed also for bone cells. This is supported by non-apoptotic appearance of FasL during osteogenesis and by significant bone alterations unrelated to apoptosis in FasL deficient (gld) mice. The molecular mechanism behind this novel role has not yet been revealed. In this report, intramembranous bone, where osteoblasts differentiate directly from mesenchymal precursors without intermediary chondrogenic step, was investigated. Mouse mandibular bone surrounding the first lower molar was used as a model. The stage where a complex set of bone cells (osteoblasts, osteocytes, osteoclasts) is first present during development was selected for an initial examination. Immunohistochemical staining detected FasL in non-apoptotic cells at this stage. Further, FasL deficient vs. wild type samples subjected to osteogenic PCR Array analysis displayed a significantly decreased expression of Mmp2 in gld bone. To examine the possibility of this novel FasL-Mmp2 relationship, intramembranous bone-derived osteoblastic cells (MC3T3-E1) were treated with anti FasL antibody or rmFasL. Indeed, the FasL neutralization caused a decreased expression of Mmp2 and rmFasL added to the cells resulted in the opposite effect. Since Mmp2 -/- mice display age-dependent alterations in the intramembranous bone, early stages of gld mandibular bone were examined and age-dependent phenotype was confirmed also in gld mice. Taken together, the present in vivo and in vitro findings point to a new non-apoptotic function of FasL in bone development associated with Mmp2 expression. PMID- 30283359 TI - Lysophosphatidic Acid Is Associated With Cardiac Dysfunction and Hypertrophy by Suppressing Autophagy via the LPA3/AKT/mTOR Pathway. AB - Background: Lysophosphatidic acid (LPA), as a phospholipid signal molecule, participates in the regulation of various biological functions. Our previous study demonstrated that LPA induces cardiomyocyte hypertrophy in vitro; however, the functional role of LPA in the post-infarct heart remains unknown. Growing evidence has demonstrated that autophagy is involved in regulation of cardiac hypertrophy. The aim of the current work was to investigate the effects of LPA on cardiac function and hypertrophy during myocardial infarction (MI) and determine the regulatory role of autophagy in LPA-induced cardiomyocyte hypertrophy. Methods: In vivo experiments were conducted in Sprague-Dawley rats subjected to MI surgery or a sham operation, and rats with MI were assigned to receive an intraperitoneal injection of LPA (1 mg/kg) or vehicle for 5 weeks. The in vitro experiments were conducted in H9C2 cardiomyoblasts. Results: LPA treatment aggravated cardiac dysfunction, increased cardiac hypertrophy, and reduced autophagy after MI in vivo. LPA suppressed autophagy activation, as indicated by a decreased LC3II-to-LC3I ratio, increased p62 expression, and reduced autophagosome formation in vitro. Rapamycin, an autophagy enhancer, attenuated LPA-induced autophagy inhibition and H9C2 cardiomyoblast hypertrophy, while autophagy inhibition with Beclin1 siRNA did not further enhance the hypertrophic response in LPA-treated cardiomyocytes. Moreover, we demonstrated that LPA suppressed autophagy through the AKT/mTOR signaling pathway because mTOR and PI3K inhibitors significantly prevented LPA-induced mTOR phosphorylation and autophagy inhibition. In addition, we found that knockdown of LPA3 alleviated LPA-mediated autophagy suppression in H9C2 cardiomyoblasts, suggesting that LPA suppresses autophagy through activation of the LPA3 and AKT/mTOR pathways. Conclusion: These findings suggest that LPA plays an important role in mediating cardiac dysfunction and hypertrophy after a MI, and that LPA suppresses autophagy through activation of the LPA3 and AKT/mTOR pathways to induce cardiomyocyte hypertrophy. PMID- 30283356 TI - Guidance Molecules in Vascular Smooth Muscle. AB - Several highly conserved families of guidance molecules, including ephrins, Semaphorins, Netrins, and Slits, play conserved and distinct roles in tissue remodeling during tissue patterning and disease pathogenesis. Primarily, these guidance molecules function as either secreted or surface-bound ligands that interact with their receptors to activate a variety of downstream effects, including cell contractility, migration, adhesion, proliferation, and inflammation. Vascular smooth muscle cells, contractile cells comprising the medial layer of the vessel wall and deriving from the mural population, regulate vascular tone and blood pressure. While capillaries lack a medial layer of vascular smooth muscle, mural-derived pericytes contribute similarly to capillary tone to regulate blood flow in various tissues. Furthermore, pericyte coverage is critical in vascular development, as perturbations disrupt vascular permeability and viability. During cardiovascular disease, smooth muscle cells play a more dynamic role in which suppression of contractile markers, enhanced proliferation, and migration lead to the progression of aberrant vascular remodeling. Since many types of guidance molecules are expressed in vascular smooth muscle and pericytes, these may contribute to blood vessel formation and aberrant remodeling during vascular disease. While vascular development is a large focus of the existing literature, studies emerged to address post-developmental roles for guidance molecules in pathology and are of interest as novel therapeutic targets. In this review, we will discuss the roles of guidance molecules in vascular smooth muscle and pericyte function in development and disease. PMID- 30283360 TI - Proteomics Analysis of Myocardial Tissues in a Mouse Model of Coronary Microembolization. AB - Coronary microembolization (CME) is an important clinical problem, and it is related to poor outcome. The specific molecular mechanisms of CME are not fully understood. In the present study, we established a mice model of CME. Isobaric tags for relative and absolute quantitation (iTRAQ) and liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) technologies identified 249 differentially expressed proteins in the myocardial tissues of CME mice as compared with sham-operated mice. Bioinformatics analysis demonstrated that these differentially expressed proteins were enriched in several energy metabolism or cytoskeleton organization related processes or pathways. Quantitative PCR and Western blotting validation experiments revealed that succinate dehydrogenase (SDHA and SDHB) were upregulated, Rho GDP dissociation inhibitor alpha (RhoGDIalpha) and Filamin-A (FLNA) were downregulated significantly in CME mice. These findings indicated that the alternations of the cytoskeleton and energy metabolism pathways play important roles in the pathogenesis of CME, future studies are warranted to verify if targeting these molecules might be useful to alleviate CME injury or not. PMID- 30283361 TI - Additional Intra- or Inter-session Balance Tasks Do Not Interfere With the Learning of a Novel Balance Task. AB - Background: It has been shown that balance training induces task-specific performance improvements with very limited transfer to untrained tasks. Thus, regarding fall prevention, one strategy is to practice as many tasks as possible to be prepared for a multitude of situations with increased fall risk. However, it is not clear whether the learning of several different balance tasks interfere with each other. A positive influence could be possible via the contextual interference (CI) effect, a negative influence could be induced by the disruption of motor memory during consolidation or retrieval. Methods: In two 3-week training experiments, we tested: (1) whether adding an additional balance task in the same training session would influence the learning of a balance task [first task: one-leg stance on a tilt-board (TB), six sessions, 15 * 20 s per session; additional task: one-leg stance on a slack line (SL), same amount of additional training]; (2) whether performing a different balance task (SL) in between training sessions of the first task (TB) would influence the learning of the first task. Twenty-six healthy subjects participated in the first experiment, 40 in the second experiment. In both experiments the participants were divided into three groups, TB only, TB and SL, and control. Before and after the training period, performance during the TB task (3 * 20 s) was recorded with a Vicon motion capturing system to assess the time in equilibrium. Results: Analyses of variance revealed that neither the additional intra-session balance task in experiment 1 nor the inter-session task in experiment 2 had a significant effect on balance performance improvement in the first task (no significant group * time interaction effect for the training groups, p = 0.83 and p = 0.82, respectively, only main effects of time). Conclusion: We could not find that additional intra- or intersession balance tasks interfere with the learning of a balance task, neither impairing it nor having a significant positive effect. This can also be interpreted as further evidence for the specificity of balance training effects, as different balance tasks do not seem to elicit interacting adaptations. PMID- 30283362 TI - A Review of the Inhibition of the Mitochondrial ATP Synthase by IF1 in vivo: Reprogramming Energy Metabolism and Inducing Mitohormesis. AB - The ATPase Inhibitory Factor 1 (IF1) is the physiological inhibitor of the mitochondrial ATP synthase. Herein, we summarize the regulation of the expression and activity of IF1 as a main driver of the activity of oxidative phosphorylation (OXPHOS) in mammalian tissues. We emphasize that the expression of IF1, which is a mitochondrial protein with very short half-life, is tissue-specifically expressed and primarily controlled at posttranscriptional levels. Inhibition of the activity of IF1 as inhibitor of the ATP synthase under normal physiological conditions is exerted by phosphorylation of S39 by a cAMP-dependent PKA-like activity of mitochondria in response to different physiological cues. Conditional tissue-specific transgenic mice overexpressing IF1 in colon, or a mutant active version of IF1 (IF1-H49K) in liver or in neurons, revealed the inhibition of the ATP synthase and the reprograming of energy metabolism to an enhanced glycolysis. In the IF1-H49K models, the assembly/activity of complex IV and the superassembly of complex V are also affected. Moreover, the IF1-mediated inhibition of the ATP synthase generates a reactive oxygen species (mtROS) signal that switches on the expression of nuclear genes that facilitate adaptation to a restrained OXPHOS. In contrast to normal mice, metabolically preconditioned animals are partially protected from the action of cytotoxic agents by upgrading the activation of stress kinases and transcription factors involved in resolving metabolic adaptation, the antioxidant response, cell survival, and the immune response of the tissue microenvironment. Altogether, we stress a fundamental physiological function for the ATP synthase and its inhibitor in mitohormesis. PMID- 30283365 TI - Mental Health in Anesthesiology and ICU Staff: Sense of Coherence Matters. AB - Background: Hospitals, and particularly intensive care units (ICUs), are demanding and stressful workplaces. Physicians and nurse staff are exposed to various stressors: emergency situations, patients' deaths, and team conflicts. Correspondingly, several studies describe increased rates of PTSD symptoms and other mental health problems in hospital staff. Therefore, it is important to identify factors that lower the risk of psychopathological symptoms. High levels of sense of coherence (SOC) and general resilience as well as an internal locus of control (LOC) have already been identified as important health-benefitting factors in medical staff. The current study aimed to evaluate their unique impact in an ICU and an anesthesiology unit. Method: The cross-sectional online survey investigated SOC, LOC, general resilience, general mental health problems as well as PTSD symptoms in nurses and physicians within an ICU and an anesthesiology unit (N = 52, 65.4% female). General mental health problems were assessed using the ICD-10-Symptom-Rating (ISR) and PTSD symptoms were measured using the PTSD Checklist for DSM-5 (PCL-5). The Sense of Coherence Scale (SOC-L9) assessed SOC, the Resilience Scale (RS-11) measured general resilience, and LOC was determined using a 4-item scale for the assessment of control beliefs (IE-4). Results: As expected, SOC, r = -0.72, p < 0.001, general resilience, r = -0.46, p < 0.001, and internal LOC, r = -0.51, p < 0.001, were negatively correlated with general mental health problems while an external LOC showed a positive association, r = 0.35, p = 0.010. However, in a multiple regression model, R 2 = 53.9%, F (4, 47) = 13.73, p < 0.001, only SOC significantly predicted general mental health problems by uniquely accounting for 13% of the variance. For PTSD symptoms, which were highly correlated with general mental health problems, a similar pattern of results was found. Conclusion: SOC was found to be the most important correlate of both general mental health problems and PTSD symptoms in an ICU and an anesthesiology unit. Thus, if further evidenced by longitudinal studies, implementing interventions focusing on an enhancement of SOC in training programs for ICU and anesthesiology unit staff might be a promising approach to prevent or reduce psychopathological symptoms. PMID- 30283363 TI - Efficacy and Safety of Varenicline for Smoking Cessation in Schizophrenia: A Meta Analysis. AB - Objective: Smoking represents a major public health problem among patients with schizophrenia. To this end, some studies have investigated the efficacy of varenicline for facilitating smoking cessation in schizophrenia patients. The present review seeks to synthesize the results of these studies as well as document the reported side effects of using this medication. Methods: An electronic search was performed using five major databases: PubMed, Scopus, EMBASE, Web of Science, and Cochrane Library. Included in the current analysis were randomized clinical trials (RCTs) that have investigated the effect of varenicline in promoting smoking cessation in patients with schizophrenia. Risk of bias among included RCTs was assessed using the Cochrane Collaboration's quality assessment tool. Results: Among the 828 screened articles, only four RCTs, which involved 239 participants, were eligible for meta-analysis. In patients with schizophrenia, varenicline treatment when compared to placebo significantly reduced the number of cigarettes consumed per day [SMD (95% CI) = 0.89(0.57-1.22)] and expired carbon monoxide levels [SMD (95% CI) = 0.50 (0.06 0.94)] respectively. Conclusion: Despite a limited number of studies included in the meta-analysis, our results suggest that varenicline is an effective and safe drug to assist smoking cessation in patients with schizophrenia. Future large scale well-designed RCTs are required to validate these findings.

AB - Background: MU-opioid receptor knockout (MOP-KO) mice display baseline hyperalgesia. We have recently identified changes in tissue volume in the periaqueductal gray matter (PAG) using magnetic resonance imaging voxel-based morphometry. Changes in the structure and connectivity of this region might account for some behavior phenotypes in MOP-KO mice, including hyperalgesia. Methods: Adult male MOP-KO and wild-type (WT) mice were studied. Immunohistochemistry was performed to detect microglia, astrocytes, and neurons in the PAG using specific markers: ionized calcium-binding adaptor molecule 1 (Iba-1) for microglia, glial fibrillary acidic protein (GFAP) for astrocytes, and the neuronal nuclei antigen (NeuN; product of the Rbfox3 gene) for neurons, respectively. Cell counting was performed in the four parallel longitudinal columns of the PAG (dorsomedial, dorsolateral, lateral, and ventrolateral) at three different locations from bregma (-3.5, -4.0, and -4.5 mm). Results: The quantitative analysis showed larger numbers of well-distributed Iba1-IR cells (microglia), NeuN-IR cells (neurons), and GFAP-IR areas (astrocytes) at all the anatomically distinct regions examined, namely, the dorsomedial (DM) PAG, dorsolateral (DL) PAG, lateral (L) PAG, and ventrolateral (VL) PAG, in MOP-KO mice than in control mice. Conclusions: The cellular changes in the PAG identified in this paper may underlie aspects of the behavioral alterations produced by MOP receptor deletion, and suggest that alterations in the cellular structure of the PAG may contribute to hyperalgesic states.

AB - A series of 14beta-acyl substituted 17-cyclopropylmethyl-7,8 dihydronoroxymorphinone compounds has been synthesized and evaluated for affinity and efficacy for mu (MOP), kappa (KOP), and delta (DOP) opioid receptors and nociceptin/orphanin FQ peptide (NOP) receptors. The majority of the new ligands displayed high binding affinities for the three opioid receptors, and moderate affinity for NOP receptors. The affinities for NOP receptors are of particular interest as most classical opioid ligands do not bind to NOP receptors. The predominant activity in the [35S]GTPgammaS assay was partial agonism at each receptor. The results are consistent with our prediction that an appropriate 14beta side chain would access a binding site within the NOP receptor and result in substantially higher affinity than displayed by the parent compound naltrexone. Molecular modeling studies, utilizing the recently reported structure of the NOP receptor, are also consistent with this interpretation. PMID- 30283368 TI - Psychopathology-a Precision Tool in Need of Re-sharpening. AB - Psychopathology is the scientific exploration of abnormal mental states that, for more than a century, has provided a Gestalt for psychiatric disorders and guided clinical as well as scientific progress in modern psychiatry. In the wake of the immense technical advances, however, psychopathology has been increasingly marginalized by neurobiological, genetic, and neuropsychological research. This ongoing erosion of psychiatric phenomenology is further fostered by clinical casualness as well as pressured health care and research systems. The skill to precisely and carefully assess psychopathology in a qualified manner used to be a core attribute of mental health professionals, but today's curricula pay increasingly less attention to its training, thus blurring the border between pathology and variants of the "normal" further. Despite all prophecies that psychopathology was doomed, and with neurobiological parameters having yet to show their differential-diagnostic superiority and value for differential indication, psychiatric diagnosis continues to rely exclusively on psychopathology in DSM-5 and ICD-11. Their categorical systematic, however, is equally challenged, and, supported by advances in machine learning, a personalized symptom-based approach to precision psychiatry is increasingly advocated. The current paper reviews the objectives of psychopathology and the recent debate on the role of psychopathology in future precision psychiatry-from guiding neurobiological research by relating neurobiological changes to patients' experiences to giving a framework to the psychiatric encounter. It concludes that contemporary research and clinic in psychiatry do not need less but rather more differentiated psychopathologic approaches in order to develop approaches that integrate professional knowledge and patients' experience. PMID- 30283367 TI - The Role of Amygdala in Patients With Euthymic Bipolar Disorder During Resting State. AB - The current study aims to explore the functional changes of the amygdala in patients with euthymic Bipolar Disorder (BD) using resting state fMRI (rs-fMRI). Twenty-one euthymic patients with bipolar disorder and 28 healthy controls participated in this study. Two of the euthymic patients with BD and three of the healthy controls were excluded due to excessive head motion. We found that patients with euthymia (38.79 +/- 12.03) show higher fALFF (fractional Amplitude of low-frequency fluctuation) value of the amygdala (t = 2.076, P = 0.044), and lower functional connectivity between the amygdala and supplementary motor area (p < 0.01, GRF corrected) than healthy controls (33.40 +/- 8.21). However, euthymic patients did not show a differential activity in ReHo (Regional Homogeneity) and gray matter of the amygdala region as compared to healthy controls. Thus, despite the absence of clinical symptoms in euthymic patients with BD, the amygdala functional activity and its connectivity to other brain regions remain altered. Further investigation of negative emotions and social functioning in euthymic patients with BD are needed and can help pave the way for a better understanding of BD psychopathology. PMID- 30283369 TI - Recursive Combination Has Adaptability in Diversifiability of Production and Material Culture. AB - It has been suggested that hierarchically structured symbols, a remarkable feature of human language, are produced via the operation of recursive combination. Recursive combination is frequently observed in human behavior, not only in language but also in action sequences, mind-reading, technology, etc. in contrast, it is rarely observed in animals. Why is it that only humans use this operation? What is the adaptability of recursive combination? We aim (1) to identify the environmental feature(s) in which recursive combination is effective for survival and reproduction, and that has facilitated the evolution of this ability, and (2) to demonstrate the possible evolutionary processes of recursive combination. To achieve this, we constructed an evolutionary simulation of agents that generated products using recursive combination and used the results to explore the types of fitness functions (that reflect the kinds of adaptive environments) that give rise to this ability. We identified two types of adaptability of the recursive combination: (1) diversifiability of production and (2) diversifiability of products. Through the former, recursive combination promotes robustness against failure of production caused by inaccurate manipulations or irreversible changes. In an environment in which diversified products are preferable, sharing a portion of the production process for these products entails producing multiple products in which recursive combination plays a key role. We suppose that recursive combination works as a driving force of material culture. Finally, we discuss the possible evolutionary scenarios of recursive combination that is later generalized to encompass many aspects of human cognition, including human language. PMID- 30283370 TI - Factor Structure of Urdu Version of the Flourishing Scale. AB - Background: A great deal of research has been carried out on the assessment of the eudaimonic perspective of psychological well-being and the hedonic perspective of subjective well-being. The Flourishing Scale (FS) has been extensively used in research and practice, as it assesses the fundamental aspects of social psychological functioning. Nevertheless, the psychometric properties of Urdu versions of eudaimonic measures, such as the FS, have not yet been ascertained. The translation and validation of the FS in the Urdu language was not available, and hence this study was planned with the aim to validate the Urdu version of the FS. Methods: We assessed the psychometric properties of the FS in a sample of adults aged 18 years and above in Pakistan (N = 130) using exploratory factor analysis based on principal component analysis with varimax rotation and confirmatory factor analysis. Results: The exploratory factor analysis confirmed the unidimensional nature of the 8-item FS. We assessed that the Urdu version of the FS showed a high internal consistency reliability (alpha = 0.914) with a significant intraclass correlation coefficient (ICC), p < 0.001). In our study, the Kaiser-Mayer-Olkin value was 0.915 with a chi-square test value (chi2) of 637.687, and Bartlett's test of sphericity was significant (df = 28, p < 0.001). The intraclass correlation coefficients (ICCs) at test-retest for all domains were statistically significant (p < 0.001) and showed excellent agreement for all the items. The revised confirmatory factor analysis revealed a good-fit model, but with item 8-"People respect me"-removed due to its lower factor loading. Conclusions: The findings suggest that the FS is a psychometrically sound instrument for assessing social psychological functioning among adults in Pakistan. Therefore, the validated Urdu version of the FS may be used in future studies of well-being in clinical psychology and positive psychology. PMID- 30283371 TI - Steps Toward an Integrative Clinical Systems Psychology. AB - Clinical fields of the "sciences of the mind" (psychotherapy, psychiatry, etc.) lack integrative conceptual frameworks that have explanatory power. Mainly descriptive-classificatory taxonomies like DSM dominate the field. New taxonomies such as Research Domain Criteria (RDoC) aim to collect scientific knowledge regarding "systems" for "processes" of the brain. These terms have a supradisciplinary" meaning if they are considered in context of Systems Science. This field emerges as a platform of theories like general systems theory, catastrophe theory, synergetics, chaos theory, etc. It provides a lot of abstract concepts, constructs, methods and models. We assume that these tools also enable theoretical integration in the diversified field of clinical practice in the sciences of the mind. Additionally, systems thinking in clinical psychology improves conceptual links to currently network-oriented neurobiology. However, clear definitions of systemic terms are necessary to emerge from their mainly metaphorical use. Here we revise mainly terms like "structure", "process" and "dynamics" as they are used already in psychology, psychoanalysis, psychopathology and psychiatry in an ill-defined way. For instance, affective cognitive structures like "life space" or "object representations" can be seen as products of mental processing. These structures, in turn, modulate dynamics of mental processes. Additionally, we suggest a coupled network concept of emotions and motivations as the main subsystem that modulates mental dynamics that results in a qualitative systemic model of the mind. Finally, we assume that a revisited systemic approach could improve interdisciplinary understanding of the mental. PMID- 30283372 TI - Why Do You Ride?: A Characterization of Mountain Bikers, Their Engagement Methods, and Perceived Links to Mental Health and Well-Being. AB - Mountain biking is an increasingly popular outdoor activity on the extreme sport continuum. Extreme and high-risk sports have been investigated using a variety of motivational theories with sensation seeking a dominant theme; however, behavioral and motivational homogeneity within these types of populations should not be assumed. Recent studies have highlighted the therapeutic potential of extreme sports and similar outdoor activities. The aim of this study was to describe the characteristics of mountain biking participants, their engagement methods, and perceived benefits to mental health and well-being. This was a cross sectional survey and participants were recruited via social media. An online questionnaire specific to the domain of mountain biking was developed. Analysis of the full sample (n = 1,484) and of three independent paired sub-samples was conducted using SPSS. The sub-samples compared the results of males and females; younger and older riders; and those who have recently engaged in downhill mountain biking and those who have not. The results have succeeded in identifying some disparities in mountain biker characteristics and engagement methods. The results suggest that some riders found pleasure in higher risk engagement. The study proposes various explanations for the disproportion of women in mountain biking. Irrespective of the confounding factors related to rider characteristics or engagement methods, mountain bikers reported copious benefits to mental health and well-being related to their engagement. There was a high reported usage of mountain biking as a coping strategy. As such, this study provides insights that could inform the development of outdoor activities as interventions for mental health. PMID- 30283373 TI - Exploring Narrative Structure and Hero Enactment in Brand Stories. AB - This study examines how audiovisual brand stories both invite and enable consumers to enact heroic archetypes. Integrating research on the archetypal structure of narratives with research on the event structure of narratives, we distinguish singular plot stories (i.e., stories that show a Hero's Journey) from embedded plot stories (i.e., stories that not only show but also tell one or more Hero's Journeys) and develop a conceptual and narratological framework to analyze their structural elements. Application of the framework to 20 brand stories representing 8 different brands reveals meaningful variation in elements between the singular plot stories and embedded plot stories. Differences in the expression of archetypes and event structure are argued to evoke different types of Hero enactment which in turn result in different outcomes. We specifically hypothesize that the enactment of heroic archetypes in singular plot stories primarily results in catharsis (pleasure), whereas the enactment of heroic archetypes in embedded plot stories primarily results in an outcome we describe as phronesis: a form of moral sense making of the self that advances one's practical wisdom and prudence. The final section of the paper discusses how cathartic and phronetic outcomes of hero enactment may foster the psychological bonding between brand and consumer, and invite consumers to align their moral values with the values that are reflected by heroic character traits. The central aims of the analysis presented are to provide an exploration of narrative phenomena in a reasonably broad range of brand story videos and foremost to provide a conceptual framework with an applicable instrument suited to analyze relevant categories in these brand stories. The present study is interdisciplinary in its approach to a contemporary, developing marketing phenomenon, applying psychological modeling of archetypes and heroic values with narratological insights on perspective-taking and story structure. Its contribution is to systemize, from a narratological viewpoint, how various narrative archetypes in brand video stories may contribute to the development of brand-consumer relations. PMID- 30283374 TI - Social Interaction Patterns of the Disabled People in Asymmetric Social Dilemmas. AB - The social participation of the disabled people is unsatisfactory and low, one of the reasons often overlooked but of great importance may lie in the disparate patterns of social interaction between the disabled people and the abled people. The current study respectively recruited 41 and 80 disabled people in two experiments and adopted give-some games and public good dilemma to explore social interaction patterns between the disabled abled people. The results were as follows: (1) the disabled people preferred to interact with the disabled people and the abled people preferred to interact with the abled people. (2) The disabled abled people had higher cooperation, satisfaction and sense of justice when interacting with the disabled people than interacting with the abled people. (3) Advantage in the number of the disabled people could reverse their disadvantage in the identity. These results are of important practical value, which provides related theoretical support for the disabled people's federation and communities when carrying out activities for the disabled people. PMID- 30283375 TI - Factor Score Regression With Social Relations Model Components: A Case Study Exploring Antecedents and Consequences of Perceived Support in Families. AB - The family social relations model (SRM) is applied to identify the sources of variance in interpersonal dispositions in families, but the antecedents or consequences of those sources are rarely investigated. Simultaneous modeling of the SRM with antecedents or consequences using structural equation modeling (SEM) allows to do so, but may become computationally prohibitive in small samples. We therefore consider two factor score regression (FSR) methods: regression and Bartlett FSR. Based on full information maximum likelihood (FIML), we derive closed-form expressions for the regression and Bartlett factor scores in the presence of missingness. A simulation study in both a complete- and incomplete case setting compares the performance of these FSR methods with SEM and an ANOVA based approach. In both settings, the regression FIML factor scores as explanatory variable produces unbiased estimators with precision comparable to the SEM-estimators. When SRM-effects are used as dependent variables, none of the FSR methods are a suitable alternative for SEM. The latter result deviates from previous studies on FSR in more simple settings. As an example, we explore whether gender and past victimhood of relational and physical aggression are antecedents for family dynamics of perceived support, and whether those dynamics predict physical and relational aggression. PMID- 30283376 TI - Body-as-Subject in the Four-Hand Illusion. AB - In a recent study (Chen et al., 2018), we conducted a series of experiments that induced the "four-hand illusion": using a head-mounted display (HMD), the participant adopted the experimenter's first-person perspective (1PP) as if it was his/her own 1PP. The participant saw four hands via the HMD: the experimenter's two hands from the adopted 1PP and the subject's own two hands from the adopted third-person perspective (3PP). In the active four-hand condition, the participant tapped his/her index fingers, imitated by the experimenter. Once all four hands acted synchronously and received synchronous tactile stimulations at the same time, many participants felt as if they owned two more hands. In this paper, we argue that there is a philosophical implication of this novel illusion. According to Merleau-Ponty (1945/1962) and Legrand (2010), one can experience one's own body or body-part either as-object or as subject but cannot experience it as both simultaneously, i.e., these two experiences are mutually exclusive. Call this view the Experiential Exclusion Thesis. We contend that a key component of the four-hand illusion-the subjective experience of the 1PP-hands that involved both "kinesthetic sense of movement" and "visual sense of movement" (the movement that the participant sees via the HMD)-provides an important counter-example against this thesis. We argue that it is possible for a healthy subject to experience the same body-part both as subject and as-object simultaneously. Our goal is not to annihilate the distinction between body-as-object and body-as-subject, but to show that it is not as rigid as suggested by the phenomenologists. PMID- 30283378 TI - Long-Range Correlation Underlying Childhood Language and Generative Models. AB - Long-range correlation, a property of time series exhibiting relevant statistical dependence between two distant subsequences, is mainly studied in the statistical physics domain and has been reported to exist in natural language. By using a state-of-the-art method for such analysis, long-range correlation is first shown to occur in long CHILDES data sets. To understand why, generative stochastic models of language, originally proposed in the cognitive scientific domain, are investigated. Among representative models, the Simon model is found to exhibit surprisingly good long-range correlation, but not the Pitman-Yor model. Because the Simon model is known not to correctly reflect the vocabulary growth of natural languages, a simple new model is devised as a conjunct of the Simon and Pitman-Yor models, such that long-range correlation holds with a correct vocabulary growth rate. The investigation overall suggests that uniform sampling is one cause of long-range correlation and could thus have some relation with actual linguistic processes. PMID- 30283377 TI - Games Used With Serious Purposes: A Systematic Review of Interventions in Patients With Cerebral Palsy. AB - The purpose of the present systematic review was to examine extant research regarding the role of games used seriously in interventions with individuals with cerebral palsy. Therefore, PubMed, PsyINFO, Web of Science, Scopus, and IEEE databases were used. Search terms included: "serious games" OR "online games" OR "video games" OR "videogame" OR "game based" OR "game" AND "intervention" AND "cerebral palsy." After the full reading and quality assessment of the papers, 16 studies met the inclusion criteria. The majority of the studies reported high levels of compliance, motivation, and engagement with game-based interventions both at home and at the clinical setting intervention. Regarding the effectiveness of the use of games, the results of the studies show both positive and negative results regarding their effectiveness. The efficacy was reported to motor function (i.e., improvements in the arm function, hand coordination, functional mobility, balance and gait function, postural control, upper-limbs function) and physical activity. Findings of this review suggest that games are used as a complement to conventional therapies and not as a substitute. Practitioners often struggle to get their patients to complete the assigned homework tasks, as patients display low motivation to engage in prescribed exercises. Data of this review indicates the use of games as tools suited to promote patients' engagement in the therapy and potentiate therapeutic gains. PMID- 30283379 TI - Humble Leadership, Psychological Safety, Knowledge Sharing, and Follower Creativity: A Cross-Level Investigation. AB - The leadership literature has provided growing evidence regarding the power of leadership in facilitating follower creativity. Despite these advances, a noticeable omission in this body of research is humble leadership. The study extends previous research by developing a cross-level moderated mediation model and examining the roles that psychological safety and knowledge sharing may play in the relationship between humble leadership and follower creativity. Using a time-lagged data of 328 team members nested within 106 teams, the results show that: (a) psychological safety mediates the relationship between humble leadership and follower creativity; (b) knowledge sharing moderates the relationship between psychological safety and follower creativity; and (c) the indirect influence of humble leadership on follower creativity through psychological safety is stronger when knowledge sharing is high. PMID- 30283381 TI - Career Ambition as a Way of Understanding the Relation Between Locus of Control and Self-Perceived Employability Among Psychology Students. AB - Employability is one of the core concepts for the future career. Students' self perceived employability is the concept that connects students' present context of education with their future professional engagement. Students' self-perceived employability is defined as the capacity to gain and keep employment in line with their future qualification level. Locus of control is a concept that explains where the person situates the causation of various life events. It is found that internal locus of control was related to different aspects of career success. Career ambition is regarded as a proxy for students' future career success. Both internal locus of control and ambition lead to proactive behaviors that are relevant for employability and consequently result in securing a sustainable job. The aim of this mixed-method study was to investigate the relations among locus of control, ambition and students' self-perceived employability. Firstly, we tested mediating role of career ambition in relation of internal locus of control and students' self-perceived employability, then we turned to qualitative analysis of students' career self-SWOT analyses in order to deepen and enrich quantitative findings. The sample consisted of 124 undergraduate psychology students that filled out Levenson's Internality subscale from IPC locus of control scale, Rothwell et al. (2008) Ambition subscale, and three items extracted from the Self-perceived employability subscale. Majority of the survey participants (N = 100) filled out personal career SWOT analysis. The mediation analysis showed that career ambition had a mediating role in the relation between the locus of control and employability. Students perceived personal capabilities and ambition as internal strengths and lack of ambition as a major internal weakness. As external opportunities students perceived various chances for developing professional skills, whereas as external threats they perceived limited opportunities in job market. In order to support university students to develop employability and future career success, university curricula should support developing future work skills that, in addition to functional competences and personal resources, entail career ambition, ways of utilizing external opportunities and dealing with job market threats. PMID- 30283380 TI - The Impact of Postpartum Posttraumatic Stress and Depression Symptoms on Couples' Relationship Satisfaction: A Population-Based Prospective Study. AB - The couple relationship is of particular importance in the transition to parenthood and in the early childhood years because it is related to the well being and mental health of partners, children, and the family. One factor that may substantially influence relationship quality and couple satisfaction after childbirth is the woman's experience of birth. Approximately 2-4% of women develop posttraumatic stress disorder (PTSD) after childbirth, with potentially wide-ranging negative consequences for the women themselves and their families. To date, some qualitative studies have explored the influence of postpartum PTSD on couple relationship satisfaction. However, quantitative studies are sparse, with mixed results and methodological limitations. We hypothesized that postpartum PTSD will be prospectively associated with low couple relationship satisfaction, even when taking into account a variety of potential confounding variables, and that the effect of postpartum PTSD symptoms on couple relationship satisfaction will be mediated by postpartum depression symptoms. This study is based on data from the Akershus Birth Cohort study, a prospective cohort study. Information from hospital records and questionnaires completed at 17 weeks gestational age, as well as at 8 weeks and 2 years postpartum were used (n = 1480). PTSD symptoms were measured by the Impact of Event Scale and couple relationship satisfaction was assessed using a modified version of the Mehrabians Marital Satisfaction Scale. Depressive symptoms were assessed by the Edinburgh Postnatal Depression Scale. Data were analyzed using bivariate correlations, multivariate regression analyses, and mediation analyses. Postpartum PTSD symptoms were prospectively related to low couple relationship satisfaction at 2 years postpartum, even when controlling for a considerable number of background factors. When including postpartum depression symptoms as predictor in the analyses, the effect of postpartum PTSD was no longer significant. Moreover, more detailed analyses showed that postpartum depression symptoms acted as a significant mediator, fully explaining the association of postpartum PTSD with couples' relationship satisfaction. Early detection of couples' relationship problems and the provision of professional help, particularly in high-risk couples may not only improve the quality of the couple relationship but also improve parenting and promote positive child outcomes. PMID- 30283382 TI - Remote Home-Based Virtual Training of Functional Living Skills for Adolescents and Young Adults With Intellectual Disability: Feasibility and Preliminary Results. AB - Background: Virtual Reality (VR) is acquiring increasing credibility as a tool for teaching independent living skills to people with Intellectual Disability (ID). Generalization of skills acquired during VR training into real environment seems to be feasible. Objective: To assess feasibility and verify effectiveness of a remote home-based rehabilitation, focused on functional living skills, for adolescents and young adults with ID, by using virtual apps installed on tablets. In particular, to assess if this tool can be managed independently, if it is enjoyable and simple to be used, and if the acquired skills can be generalized to the real environment of everyday life. Subjects and method: A single group, pre- and post-test research design was used. Sixteen participants with ID were included. A digital system was arranged, with a server managing communication between the database and the apps installed on tablets. In vivo tests were performed before and after the eleven sessions of VR training. Satisfaction questionnaires were also administered. Results: Statistically significant improvements were found between the pre- and post-in vivo tests, as well as between the VR training sessions, in almost all the parameters taken into account, for each app. Final questionnaires showed a good satisfaction level for both the participants and their families. Conclusion: The highly technological system was managed independently by participants with ID, who found it simple to be used, useful and even fun; generalization across settings was obtained. Results obtained require to be confirmed by future controlled studies, with larger samples. PMID- 30283383 TI - Information-Based Social Coordination Between Players of Different Skill in Doubles Pong. AB - We studied how teams of two players of different skill level intercepted approaching balls in the doubles-pong task. In this task, the two players moved their on-screen paddles along a shared interception axis, so that the approaching ball was intercepted by one of the paddles and that the paddles did not collide. Earlier work revealed the presence of a fuzzy division of interception space, with a boundary between interception domains located in the space between the two initial paddle positions. In the present study, using the performance of the players in their individual training sessions, we formed teams of players of varying skill level. We considered two accounts of how this boundary should be understood. In a first account, the players have shared knowledge of this boundary. Based on the side of the boundary at which the approaching ball will cross the interception axis, the players would decide whose paddle is to make the interception. Under this account, we expected that a better-skilled player would take responsibility for a larger interception domain, leading to a boundary closer to the lesser-skilled player. However, our analyses did not reveal any systematic effect of skill difference on the location (or degree of fuzziness) of the boundary: location of boundaries and overlap of interception domains varied over teams but were not systematically related to skill differences between team members. We did find effects of ball speed and approach angle. In a second account, the boundary emerges from (information-driven) player-player-ball interactions. An action-based model consistent with this account was able to capture all the patterns in boundary positions and overlaps that we observed. We conclude that the interception patterns that players demonstrate in the doubles pong task are best understood as emerging from the unfolding of the dynamics of the system of the two players and the ball, coupled through information. PMID- 30283384 TI - Do Narcissists Enjoy Visiting Social Networking Sites? It Depends on How Adaptive They Are. AB - Previous evidence suggests that narcissistic people tend to visit social networking sites (SNS) frequently, but the emotions accompanying their engagement on such sites has not been a significant subject of study. Therefore, we examined the relationship between narcissism and the affective experience on SNS in two different samples. To do so, we not only examined narcissism as a whole but also distinguished between adaptive and maladaptive narcissism. Results of the two studies consistently showed that: (1) narcissism as a whole was not correlated with the SNS affective experience; (2) maladaptive narcissism was predictive of a worse affective experience on SNS; and (3) partly due to a positive correlation with self-esteem, adaptive narcissism was associated with a better SNS affective experience. In addition, these findings held with SNS activities considered in simultaneity. The present research extends our understanding of the relationship between narcissism and social networking as well as that between emotion and social networking. PMID- 30283385 TI - Moderating Effects of Physical Activity and Global Self-Worth on Internalizing Problems in School-Aged Children With Developmental Coordination Disorder. AB - School-aged children with developmental coordination disorder (DCD) are at greater risk for physical inactivity, lower global self-worth, and internalizing problems, such as depression and anxiety. Based on the environmental stress hypothesis (ESH), recent research has shown that physical inactivity and lower global self-worth sequentially mediate the relationship between DCD and internalizing problems, suggesting that DCD leads to lower levels of physical activity, which in turn leads to lower levels of global self-worth, and ultimately, a greater amount of internalizing problems. However, physical activity and global self-worth may also buffer (i.e., moderate) the adverse effect of DCD on internalizing problems. To date, this has yet to be tested. Participants were 1206 children aged 12-14 years [611 boys, 79 with probable DCD (pDCD)]. All children received assessments of motor coordination, physical activity, global self-worth, and internalizing problems. Children with pDCD were less physically active, had lower self-worth, and experienced more internalizing problems compared to typically developing (TD) children (p's < 0.05). Furthermore, the moderated moderating effect (three-way interaction) of physical activity and global self-worth was also evident (p < 0.05), indicating that internalizing problems in both TD and pDCD groups decreased with concurrent increases in physical activity and global self-worth. Importantly, when compared to TD children, increases in physical activity and global self-worth were associated with a greater reduction in internalizing problems among children with pDCD. The findings support several pathways in the ESH and highlight that, in addition to improving motor skills, interventions should also target both physical activity and global self-worth to mitigate potential mental health issues for children with motor difficulties. PMID- 30283386 TI - Factorial Validity and Invariance of the 7-Item Generalized Anxiety Disorder Scale (GAD-7) Among Populations With and Without Self-Reported Psychiatric Diagnostic Status. AB - The 7-item Generalized Anxiety Disorder Scale (GAD-7) is commonly used to monitor anxiety symptoms. However, its factor structure has been inconsistent among competing models: unidimensional, two-dimensional, or higher order models. Additionally, it is unknown whether the scale has measurement invariance between populations with and without self-reported psychiatric diagnostic status. Participants were Japanese adults with self-reported anxiety disorder (AD; n = 479), self-reported AD and major depressive disorder (MDD; n = 314), or without self-reported psychiatric diagnostic status (self-reported non-MDD/AD; n = 654), who completed this questionnaire on the Internet. Confirmatory factor analyses showed the higher order model had similar fit indices to the unidimensional and two-dimensional factor models. For the higher order model of GAD-7, metric invariance was supported between the self-reported non-MDD/AD and self-reported AD status groups, and scalar invariance was supported between the self-reported AD status and self-reported AD with MDD status groups. Moreover, convergent and discriminant validity were consistent with previous findings in Western cultures. These results suggest that factor loadings are equivalent and the construct has the same meaning between the self-reported non-MDD/AD and self-reported AD status groups, and the total or sub-scale scores were comparable between self-reported AD status and self-reported AD with MDD status groups. The major limitation of this study is that the participants' diagnoses were self-reported, not confirmed by clinical structured interview. Further studies that incorporate clinical structured interviews are needed. PMID- 30283387 TI - Visualizing Psychological Networks: A Tutorial in R. AB - Networks have emerged as a popular method for studying mental disorders. Psychopathology networks consist of aspects (e.g., symptoms) of mental disorders (nodes) and the connections between those aspects (edges). Unfortunately, the visual presentation of networks can occasionally be misleading. For instance, researchers may be tempted to conclude that nodes that appear close together are highly related, and that nodes that are far apart are less related. Yet this is not always the case. In networks plotted with force-directed algorithms, the most popular approach, the spatial arrangement of nodes is not easily interpretable. However, other plotting approaches can render node positioning interpretable. We provide a brief tutorial on several methods including multidimensional scaling, principal components plotting, and eigenmodel networks. We compare the strengths and weaknesses of each method, noting how to properly interpret each type of plotting approach.

AB - Providing an inclusive and quality education for all contributes toward the Sustainable Development Goals of the United Nations. High-quality learning environments based on what works in education benefit all students and can be particularly beneficial for children with disabilities. This article contributes to advance knowledge to enhance the quality of education of students with disabilities that are educated in special schools. This research analyses in which ways, if any, interactive learning environments can be developed in special schools and create better learning opportunities for children with disabilities. A case study was conducted with students with disabilities (N = 36) and teaching staff in a special school, involving interviews and focus groups. We argue that rethinking the learning context by introducing instruction models based on interaction benefit children with disabilities and provide high-quality learning and safe and supportive relationships for these students, thereby promoting their educational and social inclusion. PMID- 30283389 TI - The Semantic Content of Abstract Concepts: A Property Listing Study of 296 Abstract Words. AB - The relation of abstract concepts to the modality-specific systems is discussed controversially. According to classical approaches, the semantic content of abstract concepts can only be coded by amodal or verbal-symbolic representations distinct from the sensory and motor systems, because abstract concepts lack a clear physical referent. Grounded cognition theories, in contrast, propose that abstract concepts do not depend only on the verbal system, but also on a variety of modal systems involving perception, action, emotion and internal states. In order to contribute to this debate, we investigated the semantic content of abstract concepts using a property generation task. Participants were asked to generate properties for 296 abstract concepts, which are relevant for constituting their meaning. These properties were categorized by a coding-scheme making a classification into modality-specific and verbal contents possible. Words were additionally rated with regard to concreteness/abstractness and familiarity. To identify possible subgroups of abstract concepts with distinct profiles of generated features, hierarchical cluster analyses were conducted. Participants generated a substantial proportion of introspective, affective, social, sensory and motor-related properties, in addition to verbal associations. Cluster analyses revealed different subcategories of abstract concepts, which can be characterized by the dominance of certain conceptual features. The present results are therefore compatible with grounded cognition theories, which emphasize the importance of linguistic, social, introspective and affective experiential information for the representation of abstract concepts. Our findings also indicate that abstract concepts are highly heterogeneous requiring the investigation of well-specified subcategories of abstract concepts, for instance as revealed by the present cluster analyses. The present study could thus guide future behavioral or imaging work further elucidating the representation of abstract concepts.

AB - In order for companies to realize their organizational visions, they need staff who are high-potential and looking toward the future. Due to the demographic, social and economic situation in Europe, the labor market is already reflecting a lack of high-quality human resources (HR), which inspires research into and planned management of high-potential, i.e., talented, employees. Companies are aware that only those organizations that recognize this area as crucial and invest resources into it will be successful in the "war for talent." The purpose of the study was to research the field of talent management from the perspective of the definition of what the talent management process means for companies, how to attract and recognize talented employees, what development activities to provide them with and how to measure their performance and progress. We employed an exploratory approach, using the method of semi-structured interviews to gather information from 21 HR professionals who work at medium-sized and large Slovenian companies. We found that these organizations use various approaches and activities to attract and develop talented employees. At two thirds of the companies, performance is measured using annual evaluation interviews, by measuring the meeting of targets and evaluations by superiors. The biggest challenges in the field are attracting talented employees and positioning the organization as a desirable employer. The study is useful primarily as an overview of the field and of best practices, which companies can use to argument their existing processes. PMID- 30283390 TI - Perceptual Restoration of Temporally Distorted Speech in L1 vs. L2: Local Time Reversal and Modulation Filtering. AB - Speech is intelligible even when the temporal envelope of speech is distorted. The current study investigates how native and non-native speakers perceptually restore temporally distorted speech. Participants were native English speakers (NS), and native Japanese speakers who spoke English as a second language (NNS). In Experiment 1, participants listened to "locally time-reversed speech" where every x-ms of speech signal was reversed on the temporal axis. Here, the local time reversal shifted the constituents of the speech signal forward or backward from the original position, and the amplitude envelope of speech was altered as a function of reversed segment length. In Experiment 2, participants listened to "modulation-filtered speech" where the modulation frequency components of speech were low-pass filtered at a particular cut-off frequency. Here, the temporal envelope of speech was altered as a function of cut-off frequency. The results suggest that speech becomes gradually unintelligible as the length of reversed segments increases (Experiment 1), and as a lower cut-off frequency is imposed (Experiment 2). Both experiments exhibit the equivalent level of speech intelligibility across six levels of degradation for native and non-native speakers respectively, which poses a question whether the regular occurrence of local time reversal can be discussed in the modulation frequency domain, by simply converting the length of reversed segments (ms) into frequency (Hz). PMID- 30283392 TI - Preschoolers Favor Their Ingroup When Resources Are Limited. AB - The present study examined how 2- to 4-year-old preschoolers in Singapore (N = 202) balance fairness and ingroup loyalty in resource distribution. Specifically, we investigated whether children would enact fair distributions as defined by an equality rule, or show partiality toward their ingroup when distributing resources, and the conditions under which one distributive strategy may take precedence over the other. In Experiment 1, children distributed four different pairs of toys between two puppets. In the Group condition, one puppet was assigned to the same group as the child while the other puppet was assigned to a different group using colored stickers in the No Group condition, no group assignments were made. Children's distributions were assessed for whether the toys were fairly (equally) distributed or unfairly (unequally) distributed in favor of either puppet. Experiment 2 was identical to the Group condition in Experiment 1, except that a third identical toy was introduced following the distribution of each toy pair. Distributions were separately assessed for whether the first two toys were fairly (equally) distributed or unfairly (unequally) distributed in favor of either puppet, and whether children distributed the third toy to the ingroup or outgroup puppet. Overall, the vast majority of children abided by an equality rule when resources were precisely enough to be shared between recipients, but distributed favorably to the ingroup member when there was limited resource availability. We found that fairness trumped ingroup loyalty except in resource distribution involving limited resources. Our results are consistent with findings from other resource distribution studies with preschoolers and similar studies measuring young infants' expectations of distributive behaviors in third-party observations. Taken together, there is evidence suggesting stability in the development of knowledge to behavior in the subdomains of fairness and ingroup loyalty. PMID- 30283393 TI - Longitudinal Task-Related Functional Connectivity Changes Predict Reading Development. AB - Longitudinal studies suggest developmentally dependent changes in lexical processing during reading development, implying a change in inter-regional functional connectivity over this period. The current study used functional magnetic resonance imaging (fMRI) to explore developmental changes in functional connectivity across multiple runs of a rhyming judgment task in young readers (8 14 years) over an average 2.5-year span. Changes in functional segregation are correlated with and predict changes in the skill with which typically developing children learn to apply the alphabetic principle, as measured by pseudoword decoding. This indicates a developmental shift in the proportion of specialized functional clusters is associated with changes in reading skill and suggests a dependency of reading development on changes of particular neural pathways, specifically decreases in transitivity is indicative of greater network integration. This work provides evidence that characteristics of these pathways, quantified using graph-theoretic metrics, can be used to predict individual differences in reading development. PMID- 30283394 TI - Shyness and Learning Adjustment in Senior High School Students: Mediating Roles of Goal Orientation and Academic Help Seeking. AB - Learning maladjustment is a common phenomenon in the context of examination oriented education system in china, especially among high school students who experience intense pressure when preparing for the national college entrance examination. Previous literature suggests that shyness may negatively affect ones' cognition, emotion, and behavioral performance and lead to academic and social maladjustment. Therefore, learning adjustment among shy high school students is a critical and practical point of inquiry. With a sample of 677 Chinese senior high school students, this study aims to assess the association between shyness and learning adjustment and related mechanisms of goal orientation (i.e., mastery-approach goals, mastery-avoid goals, performance approach goals, and performance-avoid goals) and academic help seeking (i.e., instrumental help seeking from teacher, instrumental help seeking from classmate, executive help seeking, and avoidance of help seeking). Self-report measures were adopted to collect information on: demographic characteristics, the level of shyness, goal orientation, academic help seeking, and learning adjustment. Results indicated that shyness was negatively correlated with learning adjustment, and this association was mediated by the dimensions of goal orientation and dimensions of academic help seeking. Specifically, shyness not only predicted learning adjustment through mastery-approach goals, and instrumental help seeking (teachers) but also predicted learning adjustment through the multiple mediating effects of the dimensions of goal orientation and the dimensions of academic help seeking (i.e., mastery-approach goals and instrumental help seeking from teachers, mastery-approach goals and executive help seeking, mastery-avoid goals and instrumental help seeking from classmates, mastery-avoid goals and executive help seeking, and performance-avoid goals and executive help seeking). Identifying these mediators further enables us to work out effective measures to promote shy high school students' learning adjustment. PMID- 30283396 TI - Editorial: NEUROTRAUMA: From Emergency Room to Back to Day-by-Day Life. PMID- 30283395 TI - Biomarkers of Neurodegeneration in Autoimmune-Mediated Encephalitis. AB - Progranulin (PGRN), Total-Tau (t-tau), and Neurofilament light chain (NfL) are well known biomarkers of neurodegeneration. The objective of the present study was to investigate whether these parameters represent also biomarkers in autoimmune-mediated Encephalitis (AE) and may give us insights into the pathomechanisms of AE. We retrospectively examined the concentration of PGRN in the cerebrospinal fluid (CSF) and serum of 38 patients suffering from AE in acute phase and/or under treatment. This AE cohort comprises patients with autoantibodies against: NMDAR (n = 18 patients), Caspr2 (n = 8), Lgi-1 (n = 10), GABAB(R) (n = 1), and AMPAR (n = 1). Additionally, the concentrations of NfL (n = 25) and t-tau (n = 13) in CSF were measured when possible. Follow up data including MRI were available in 13 patients. Several age-matched cohorts with neurological diseases besides neuroinflammation or neurodegeneration served as control groups. We observed that PGRN was significantly elevated in the CSF of patients with NMDAR-AE in the acute phase, but normalized at follow up under treatment (p < 0.01). In the CSF of other patients with AE PGRN was in the range of the CSF levels of control groups. T-tau was highly elevated in the CSF of patients with temporal FLAIR-signal in the MRI and in patients developing a hippocampal sclerosis. NfL was exceptionally high initially in Patients with AE with a paraneoplastic or parainfectious cause and also normalized under treatment. The normalizations of all biomarkers were mirrored in an improvement on the modified Rankin scale. The data suggest that the concentration of PGRN in CSF might be a biomarker for acute NMDAR-AE. Pathological high t-tau levels may indicate a risk for hippocampal sclerosis. The biomarker properties of NfL remain unclear since the levels decrease under treatment, but it could not predict severity of disease in this small cohort. According to our results, we recommend to measure in clinical practice PGRN and t-tau in the CSF of patients with AE. PMID- 30283397 TI - Segmentation of Peripheral Nerves From Magnetic Resonance Neurography: A Fully Automatic, Deep Learning-Based Approach. AB - Diagnosis of peripheral neuropathies relies on neurological examinations, electrodiagnostic studies, and since recently magnetic resonance neurography (MRN). The aim of this study was to develop and evaluate a fully-automatic segmentation method of peripheral nerves of the thigh. T2-weighted sequences without fat suppression acquired on a 3 T MR scanner were retrospectively analyzed in 10 healthy volunteers and 42 patients suffering from clinically and electrophysiologically diagnosed sciatic neuropathy. A fully-convolutional neural network was developed to segment the MRN images into peripheral nerve and background tissues. The performance of the method was compared to manual inter rater segmentation variability. The proposed method yielded Dice coefficients of 0.859 +/- 0.061 and 0.719 +/- 0.128, Hausdorff distances of 13.9 +/- 26.6 and 12.4 +/- 12.1 mm, and volumetric similarities of 0.930 +/- 0.054 and 0.897 +/- 0.109, for the healthy volunteer and patient cohorts, respectively. The complete segmentation process requires less than one second, which is a significant decrease to manual segmentation with an average duration of 19 +/- 8 min. Considering cross-sectional area or signal intensity of the segmented nerves, focal and extended lesions might be detected. Such analyses could be used as biomarker for lesion burden, or serve as volume of interest for further quantitative MRN techniques. We demonstrated that fully-automatic segmentation of healthy and neuropathic sciatic nerves can be performed from standard MRN images with good accuracy and in a clinically feasible time. PMID- 30283398 TI - Modulation of Cognitive and Emotional Control in Age-Related Mild-to-Moderate Hearing Loss. AB - Progressive hearing loss is a common phenomenon in healthy aging and may affect the perception of emotions expressed in speech. Elderly with mild to moderate hearing loss often rate emotional expressions as less emotional and display reduced activity in emotion-sensitive brain areas (e.g., amygdala). However, it is not clear how hearing loss affects cognitive and emotional control mechanisms engaged in multimodal speech processing. In previous work we showed that negative, task-relevant and -irrelevant emotion modulates the two types of control in younger and older adults without hearing loss. To further explore how reduced hearing capacity affects emotional and cognitive control, we tested whether moderate hearing loss (>30 dB) at frequencies relevant for speech impacts cognitive and emotional control. We tested two groups of older adults with hearing loss (HL; N = 21; mean age = 70.5) and without hearing loss (NH; N = 21; mean age = 68.4). In two EEG experiments participants observed multimodal video clips and either categorized pronounced vowels (cognitive conflict) or their emotions (emotional conflict). Importantly, the facial expressions were either matched or mismatched with the corresponding vocalizations. In both conflict tasks, we found that negative stimuli modulated behavioral conflict processing in the NH but not the HL group, while the HL group performed at chance level in the emotional conflict task. Further, we found that the amplitude difference between congruent and incongruent stimuli was larger in negative relative to neutral N100 responses across tasks and groups. Lastly, in the emotional conflict task, neutral stimuli elicited a smaller N200 response than emotional stimuli primarily in the HL group. Consequently, age-related hearing loss not only affects the processing of emotional acoustic cues but also alters the behavioral benefits of emotional stimuli on cognitive and emotional control, despite preserved early neural responses. The resulting difficulties in the multimodal integration of incongruent emotional stimuli may lead to problems in processing complex social information (irony, sarcasm) and impact emotion processing in the limbic network. This could be related to social isolation and depression observed in the elderly with age-related hearing loss. PMID- 30283399 TI - Characterization of NGFFYamide Signaling in Starfish Reveals Roles in Regulation of Feeding Behavior and Locomotory Systems. AB - Neuropeptides in deuterostomian invertebrates that have an Asn-Gly motif (NG peptides) have been identified as orthologs of vertebrate neuropeptide-S (NPS) type peptides and protostomian crustacean cardioactive peptide (CCAP)-type neuropeptides. To obtain new insights into the physiological roles of NG peptides in deuterostomian invertebrates, here we have characterized the NG peptide signaling system in an echinoderm-the starfish Asterias rubens. The neuropeptide NGFFYamide was identified as the ligand for an A. rubens NPS/CCAP-type receptor, providing further confirmation that NG peptides are orthologs of NPS/CCAP-type neuropeptides. Using mRNA in situ hybridization, cells expressing the NGFFYamide precursor transcript were revealed in the radial nerve cords, circumoral nerve ring, coelomic epithelium, apical muscle, body wall, stomach, and tube feet of A. rubens, indicating that NGFFYamide may have a variety of physiological roles in starfish. One of the most remarkable aspects of starfish biology is their feeding behavior, where the stomach is everted out of the mouth over the soft tissue of prey. Previously, we reported that NGFFYamide triggers retraction of the everted stomach in A. rubens and here we show that in vivo injection of NGFFYamide causes a significant delay in the onset of feeding on prey. To investigate roles in regulating other aspects of starfish physiology, we examined the in vitro effects of NGFFYamide and found that it causes relaxation of acetylcholine-contracted apical muscle preparations and induction of tonic and phasic contraction of tube feet. Furthermore, analysis of the effects of in vivo injection of NGFFYamide on starfish locomotor activity revealed that it causes a significant reduction in mean velocity and distance traveled. Interestingly, experimental studies on mammals have revealed that NPS is an anxiolytic that suppresses appetite and induces hyperactivity in mammals. Our characterization of the actions of NGFFYamide in starfish indicates that NPS/NG peptide/CCAP-type signaling is an evolutionarily ancient regulator of feeding and locomotion. PMID- 30283401 TI - Expression and Functional Analysis of the BCL2-Associated Agonist of Cell Death (BAD) Gene in the Sheep Ovary During the Reproductive Cycle. AB - Most ewes in China are seasonally polyestrous with normal ovulatory cycles, which is controlled by photoperiod (length of the daily light phase). These ewes are estrous in the short-day season and anestrus in the long-day season and cannot mate during anestrus. Thus seasonal breeding limits both diversification and intensification of production. If sheep can estrus all round year, it can be mated twice per year, which can greatly improve the economic benefits. To change seasonal estrus at the genetic level and cultivating new sheep breeds, it is important to understand the molecular mechanisms of seasonal breeding trait in sheep. The BCL2-associated agonist of cell death (BAD) gene being a regulator of cellular apoptosis was identified by our previous RNA-Seq, which is associated with follicular development in mammalian ovaries. However, the mechanism how BAD can regulate estrus in sheep was poorly understood. In this study, we characterized ovine BAD, including full-length mRNA cloning and protein sequence prediction, as well as BAD expression profile in Small-tailed Han (STH) sheep. The highest expression levels of BAD were observed in sheep hypothalamus, lung, and pituitary, while the lowest expression was in liver. Functional analysis of BAD was performed in primary granulosa cells of sheep. The concentration of P4 was significantly increased after RNAi interference of BAD, while P4 level was shown to be opposite after BAD overexpression in vitro. It has been found that BAD can reduce progesterone levels by promoting ovarian GC apoptosis, which might be involved in regulating the estrus cycle in sheep. PMID- 30283402 TI - Chemistry and Hypoglycemic Activity of GPR119 Agonist ZB-16. AB - This article is to highlight the chemical properties and primary pharmacology of novel GPR119 agonist ZB-16 and its analogs, which were rejected during the screening. Experiments were performed in vitro (specific activity, metabolism and cell toxicity) and in vivo (hypoglycemic activity and pharmacokinetics). ZB-16 exhibits nanomolar activity (EC50 = 7.3-9.7 nM) on target receptor GPR119 in vitro associated with hypoglycemic activity in vivo. In animals with streptozotocin-nicotinamide induced type 2 diabetes mellitus (STZ-NA T2D) daily oral dose of ZB-16 (1 mg/kg) or sitagliptin (10 mg/kg) for 28 days resulted in the reduction of blood glucose levels. The effects of ZB-16 were comparable to the hypoglycemic action of sitagliptin. ZB-16 demonstrated relatively low plasma exposition, high distribution volume, mild clearance and a prolonged half-life (more than 12 h). The present study demonstrates that the targeted search for selective GPR119 receptor agonists is a well-founded approach for developing novel drugs for the therapy of T2D. Based on the combination of high in vitro activity (compared to competitor standards), a useful ADME profile, distinct hypoglycemic activity which is comparable to the efficacy of sitagliptin in rats with experimental T2D, and the acceptable pharmacokinetic profile, we recommend the ZB-16 compound for further research. PMID- 30283403 TI - Melatonin in Assisted Reproductive Technology: A Pilot Double-Blind Randomized Placebo-Controlled Clinical Trial. AB - Purpose: To explore in a small pilot study whether oral melatonin, administered during ovarian stimulation increases clinical pregnancy rate (CPR) after IVF and what dose might be most effective. Methods: Pilot double-blind, dose-finding, placebo-controlled randomized clinical trial in private IVF clinics in Australia between September 2014 and September 2016. One hundred and sixty women having their first cycle of IVF or ICSI were randomized to receive placebo (n = 40), melatonin 2 mg (n = 41), melatonin 4 mg (n = 39), or melatonin 8 mg (n = 40) twice per day (BD) during ovarian stimulation. The primary outcome was CPR. Secondary outcomes included serum and follicular fluid (FF) melatonin concentrations, oocyte/embryo quantity/quality, and live birth rate (LBR). Analysis was performed using the intention-to-treat principle. Results: There was no difference in CPR or LBR between any of the four groups (p = 0.5). When all the doses of melatonin were compared as a group with placebo, the CPR was 21.7% for the former and 15.0% for the latter [OR 1.57 (95% CI 0.59, 4.14), p = 0.4]. There were also no differences between the groups in total oocyte number, number of MII oocytes, number of fertilized oocytes, or the number or quality of embryos between the groups. This is despite mean FF melatonin concentration in the highest dose group (8 mg BD) being nine-fold higher compared with placebo (P < 0.001). Conclusion: No significant differences were observed in CPR or oocyte and embryo parameters despite finding a nine-fold increase in FF melatonin concentration. However, this study was not sufficiently powered to assess differences in CPR and therefore, these results should be interpreted with caution. Because this was a small RCT, a beneficial effect of melatonin on IVF pregnancy rates cannot be excluded and merits confirmation in further, larger clinical trials.

AB - The arcuate nucleus of the hypothalamus is a key regulator of energy balance and glucose homeostasis. In particular, arcuate proopiomelanocortin (POMC) neurons inhibit food intake, stimulate energy expenditure and increase glucose tolerance. The interruption of insulin or glucose signaling in POMC neurons leads to glucose intolerance without changing energy homeostasis. Although it was previously shown that POMC neurons are necessary for normal glucose homeostasis, the participation of POMC neuropeptide, by mechanisms independent of energy balance, remains to be demonstrated. To study the role of POMC in the regulation of glucose homeostasis, we performed glucose and insulin tolerance tests in non-obese mice lacking hypothalamic POMC expression. We found that POMC deficiency leads to glucose intolerance and insulin resistance in female mice before the onset of obesity or hyperphagia. Conversely, POMC deficiency does not impair glucose homeostasis in non-obese male mice. Interestingly, females completely normalize both glucose and insulin tolerance after genetic POMC restoration. Next, to further study sex dimorphism of POMC neurons regarding glucose homeostasis, we measured glucose elicited changes in C-FOS by performing immunofluorescence in brain slices of POMC-EGFP mice. Remarkably, we found that glucose-induced C-FOS expression in POMC neurons is more than 3-fold higher in female than in male mice. Altogether, our results reveal a key role of arcuate POMC in the regulation of glucose homeostasis in females. Since POMC reactivation completely reverses the diabetogenic phenotype, arcuate POMC could be a potential target for diabetes therapy. PMID- 30283400 TI - Sterol Metabolism and Transport in Atherosclerosis and Cancer. AB - Cholesterol is a vital lipid molecule for mammalian cells, regulating fluidity of biological membranes, and serving as an essential constituent of lipid rafts. Mammalian cells acquire cholesterol from extracellular lipoproteins and from de novo synthesis. Cholesterol biosynthesis generates various precursor sterols. Cholesterol undergoes metabolic conversion into oxygenated sterols (oxysterols), bile acids, and steroid hormones. Cholesterol intermediates and metabolites have diverse and important cellular functions. A network of molecular machineries including transcription factors, protein modifiers, sterol transporters/carriers, and sterol sensors regulate sterol homeostasis in mammalian cells and tissues. Dysfunction in metabolism and transport of cholesterol, sterol intermediates, and oxysterols occurs in various pathophysiological settings such as atherosclerosis, cancers, and neurodegenerative diseases. Here we review the cholesterol, intermediate sterol, and oxysterol regulatory mechanisms and intracellular transport machineries, and discuss the roles of sterols and sterol metabolism in human diseases. PMID- 30283406 TI - Combination of a Latency-Reversing Agent With a Smac Mimetic Minimizes Secondary HIV-1 Infection in vitro. AB - Latency-reversing agents (LRAs) are considered a potential tool to cure human immunodeficiency virus type 1 (HIV-1) infection, but when they are taken alone, virus production by reactivated cells and subsequent infection will occur. Hence, it is crucial to simultaneously take appropriate measures to prevent such secondary HIV-1 infection. In this regard, a strategy to minimize the production of infectious viruses from LRA-reactivated cells is worth pursuing. Here, we focused on a second mitochondria-derived activator of caspases (Smac) mimetic, birinapant, to induce apoptosis in latent HIV-1-infected cells. When birinapant was administered alone, it only slightly increased the expression of caspase-3. However, in combination with an LRA (e.g., PEP005), it strongly induced the expression of caspase-3 followed by enhanced apoptosis. Importantly, the combination eliminated reactivated cells and drastically reduced HIV-1 production. Finally, we found that birinapant decreased the mRNA expression of HIV-1 that was induced by PEP005 in the primary CD4+ T-cells from HIV-1-carrying patients as well. These results suggest that the combination of an LRA and an "apoptosis-inducing" agent, such as a Smac mimetic, is a possible treatment option to decrease HIV-1 reservoirs without the occurrence of HIV-1 production by reactivated cells. PMID- 30283407 TI - Small Antimicrobial Resistance Plasmids in Livestock-Associated Methicillin Resistant Staphylococcus aureus CC398. AB - Livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) isolates of the clonal complex 398 are often resistant to a number of antimicrobial agents. Studies on the genetic basis of antimicrobial resistance in these bacteria identified SCCmec cassettes, various transposons and plasmids of different sizes that harbor antimicrobial resistance genes. While large plasmids that carry multiple antimicrobial resistance genes - occasionally together with heavy metal resistance genes and/or virulence genes - are frequently seen in LA MRSA ST398, certain resistance genes are also associated with small plasmids of up to 15 kb in size. These small resistance plasmids usually carry only one, but in rare cases also two or three antimicrobial resistance genes. In the current review, we focus on small plasmids that carry the macrolide-lincosamide streptogramin B resistance genes erm(C) or erm(T), the lincosamide resistance gene lnu(A), the pleuromutilin-lincosamide-streptogramin A resistance genes vga(A) or vga(C), the spectinomycin resistance gene spd, the apramycin resistance gene apmA, or the trimethoprim resistance gene dfrK. The detailed analysis of the structure of these plasmids allows comparisons with similar plasmids found in other staphylococci and underlines in many cases an exchange of such plasmids between LA-MRSA ST398 and other staphylococci including also coagulase-negative staphylococci. PMID- 30283408 TI - Abundant and Rare Microbial Biospheres Respond Differently to Environmental and Spatial Factors in Tibetan Hot Springs. AB - Little is known about the distribution and ecological functions of abundant, intermediate, and rare biospheres and their correlations with environmental factors in hot springs. Here, we explored the microbial community composition of total, abundant, intermediate, and rare biospheres in 66 Tibetan hot springs (pairwise geographic distance 0-610 km, temperature 32-86 degrees C, pH 3.0-9.5, and salinity 0.13-1.32 g/L) with the use of Illumina MiSeq high-throughput sequencing. The results showed that the abundant sub-communities were mainly composed of Chloroflexi, Proteobacteria, Deinococcus-Thermus, Aquificae, Bacteroidetes, and Firmicutes. In contrast, the rare sub-communities mainly consisted of most newly proposed or candidate phyla of Dictyoglomi, Hydrogenedentes, Atribacteria, Hadesarchaea, Aminicenantes, Microgenomates, Calescamantes, Omnitrophica, Altiarchaeales, and Chlamydiae. However, the abundant and rare sub-communities shared some common phyla (e.g., Crenarchaeota, Bathyarchaeota, and Chlorobi), which were composed of different OTUs. The abundant, intermediate, and rare sub-communities were mainly influenced by different environmental variables, which could be ascribed to the fact that they may have different growth and activity and thus respond differently to these variables. Spatial factors showed more contribution to shaping of the intermediate and rare communities than to abundant sub-community, suggesting that the abundant taxa were more easily dispersed than their rare counterparts among hot springs. Microbial ecological function prediction revealed that the abundant and rare sub-communities responded differently to the measured environmental factors, suggesting they may occupy different ecological niches in hot springs. The rare sub-communities may play more important roles in organic matter degradation than their abundant counterparts in hot springs. Collectively, this study provides a better understanding on the microbial community structure and potential ecological functions of the abundant and rare biospheres in hot spring ecosystems. The identified rare taxa provide new opportunities of ecological, taxonomic and genomic discoveries in Tibetan hot springs. PMID- 30283409 TI - Global Marine N2 Fixation Estimates: From Observations to Models. AB - Fixed nitrogen (N) limits productivity across much of the low-latitude ocean. The magnitude of its inventory results from the balance of N input and N loss, the latter largely occurring in regionally well-defined low-oxygen waters and sediments (denitrification and anammox). The rate and distribution of N input by biotic N2 fixation, the dominant N source, is not well known. Here we compile N2 fixation estimates from experimental measurements, tracer-based geochemical and modeling approaches, and discuss their limitations and uncertainties. The lack of adequate experimental data coverage and the insufficient understanding of the controls of marine N2 fixation result in high uncertainties, which make the assessment of the current N-balance a challenge. We suggest that a more comprehensive understanding of the environmental and ecological interaction of marine N2 fixers is required to advance the field toward robust N2 fixation rates estimates and predictions. PMID- 30283404 TI - The Gut-Kidney Axis: Putative Interconnections Between Gastrointestinal and Renal Disorders. AB - Diabetic kidney disease (DKD) is a devastating condition associated with increased morbidity and premature mortality. The etiology of DKD is still largely unknown. However, the risk of DKD development and progression is most likely modulated by a combination of genetic and environmental factors. Patients with autoimmune diseases, like type 1 diabetes, inflammatory bowel disease, and celiac disease, share some genetic background. Furthermore, gastrointestinal disorders are associated with an increased risk of kidney disease, although the true mechanisms have still to be elucidated. Therefore, the principal aim of this review is to evaluate the impact of disturbances in the gastrointestinal tract on the development of renal disorders. PMID- 30283411 TI - Molecular Epidemiology of Photobacterium damselae subsp. damselae Outbreaks in Marine Rainbow Trout Farms Reveals Extensive Horizontal Gene Transfer and High Genetic Diversity. AB - The marine bacterium Photobacterium damselae subsp. damselae is a pathogen for a variety of marine animals, as well as for humans, and is nowadays considered an emerging pathogen for fish of importance in marine aquaculture. Recent studies have suggested that outbreaks in fish farms are caused by multiclonal populations of this subspecies that exist in the environment. Here, we report the study of a collection of 31 strains isolated during the course of disease outbreaks in marine rainbow trout farms in Denmark in 1994, 1995, and 2006, respectively. A phylogenetic analysis based on the toxR gene sequence, and the screening of virulence-related genes uncovered a high genetic heterogeneity, even among strains isolated from the same fish farm at the same time. Moreover, comparative analysis of the whole genome sequences of four selected strains revealed a large number of differentially occurring genes, which included virulence genes, pPHDD1 plasmid, polysaccharide synthesis gene clusters, CRISPR-Cas systems and putative new mobile genetic elements. This study provides sound evidence that P. damselae subsp. damselae outbreaks in Danish rainbow trout farms were caused by multiclonal populations and that horizontal gene transfer constitutes a strong driving force in the generation of intraspecific diversity in this pathogen. PMID- 30283410 TI - Diet, Microbiota and Gut-Lung Connection. AB - The gut microbial community (Gut microbiota) is known to impact metabolic functions as well as immune responses in our body. Diet plays an important role in determining the composition of the gut microbiota. Gut microbes help in assimilating dietary nutrients which are indigestible by humans. The metabolites produced by them not only modulate gastro-intestinal immunity, but also impact distal organs like lung and brain. Micro-aspiration of gut bacteria or movement of sensitized immune cells through lymph or bloodstream can also influence immune response of other organs. Dysbiosis in gut microbiota has been implicated in several lung diseases, including allergy, asthma and cystic fibrosis. The bi directional cross-talk between gut and lung (termed as Gut-Lung axis) is best exemplified by intestinal disturbances observed in lung diseases. Some of the existing probiotics show beneficial effects on lung health. A deeper understanding of the gut microbiome which comprises of all the genetic material within the gut microbiota and its role in respiratory disorders is likely to help in designing appropriate probiotic cocktails for therapeutic applications.

AB - Emiliania huxleyi, a cosmopolitan coccolithophore in the modern ocean, plays an important role in the carbon cycle and local climate feedback as it can form extensive blooms, calcify, and produce dimethylsulfoniopropionate (DMSP) leading to the generation of dimethyl sulfide (DMS) which affects climate when oxidized in the atmosphere. It is known to be able to utilize dissolved organic phosphorus (DOP) by expressing a specific type of alkaline phosphatase (EHAP1) under phosphorus-limited conditions. In this study, we identified a new alkaline phosphatase (EH-PhoAaty) in this species, which we found belongs to the newly classified PhoAaty family. The expression of this atypical phosphatase was up regulated under P-depleted conditions at both the transcriptional and translational levels, suggesting that E. huxleyi is able to express this AP to cope with phosphorus limitation. Comparative analysis revealed different transcriptional expression dynamics between eh-PhoA aty and ehap1, although both genes exhibited inducible expression under phosphate deficiency. In addition, after AP activity was eliminated by using EDTA to chelate metal ions, we found that AP activity was recovered with the supplement of Ca2+ and Zn2+, indicative of the adoption of Ca2+ as the cofactor under Zn-P co-limited conditions, likely a result of adaptation to oceanic environments where Zn2+ is often limiting. PMID- 30283413 TI - A GRX1 Promoter Variant Confers Constitutive Noisy Bimodal Expression That Increases Oxidative Stress Resistance in Yeast. AB - Higher noise in the expression of stress-related genes was previously shown to confer better resistance in selective conditions. Thus, evolving the promoter of such genes toward higher transcriptional noise appears to be an attractive strategy to engineer microbial strains with enhanced stress resistance. Here we generated hundreds of promoter variants of the GRX1 gene involved in oxidative stress resistance in Saccharomyces cerevisiae and created a yeast library by replacing the native GRX1 promoter by these variants at the native locus. An outlier clone with very strong increase in noise (6-times) at the same mean expression level as the native strain was identified whereas the other noisiest clones were only 3-times increased. This variant provides constitutive bimodal expression and consists in 3 repeated but differently mutated copies of the GRX1 promoter. In spite of the multi-factorial oxidative stress-response in yeast, replacement of the native promoter by this variant is sufficient alone to confer strongly enhanced resistance to H2O2 and cumene hydroperoxide. New replacement of this variant by the native promoter in the resistant strain suppresses the resistance. This work shows that increasing noise of target genes in a relevant strategy to engineer microbial strains toward better stress resistance. Multiple promoter replacement could synergize the effect observed here with the sole GRX1 promoter replacement. Finally this work suggests that combining several mutated copies of the target promoter could allow enhancing transcriptional-mediated noise at higher levels than mutating a single copy by providing constitutive bimodal and highly heterogeneous expression distribution. PMID- 30283415 TI - Relative Level of Bacteriophage Multiplication in vitro or in Phyllosphere May Not Predict in planta Efficacy for Controlling Bacterial Leaf Spot on Tomato Caused by Xanthomonas perforans. AB - Following analysis of eight phages under in vitro, growth chamber and greenhouse conditions with the bacterial spot of tomato pathogen Xanthomonas perforans, there was no correlation between disease control efficacy and in vitro phage multiplication, in vitro bacterial suppression, or in vivo phage multiplication in the presence of the host, but there was a low correlation between phage persistence on the leaf surface and disease control. Two of the 8 virulent phages (PhiXv3-21 and PhiXp06-02) were selected for in depth analysis with two X. perforans (Xp06-2-1 and Xp17-12) strains. In in vitro experiments, phage PhiXv3 21 was equally effective in infecting the two bacterial strains based on efficiency of plating (EOP). Phage PhiXp06-02, on the other hand, had a high EOP on strain Xp06-2-1 but a lower EOP on strain Xp17-12. In several growth chamber experiments, PhiXv3-21 was less effective than phage PhiXp06-02 in reducing disease caused by strain Xp06-2-1, but provided little or no disease control against strain Xp17-12. Interestingly, PhiXp06-02 could multiply to significantly higher levels on the tomato leaf surface than phage PhiXv3-21. The leaf surface appears to be important in terms of the ability of certain bacteriophages to multiply in the presence of the bacterial host. PhiXv3-21, when applied to grapefruit leaves in combination with a bacterial host, was unable to multiply to high levels, whereas on tomato leaflets the phage multiplied exponentially. One plausible explanation is that the leaf surface may be an important factor for attachment of certain phages to their bacterial host. PMID- 30283414 TI - Scrophularia striata Extract Supports Rumen Fermentation and Improves Microbial Diversity in vitro Compared to Monensin. AB - In the search for natural alternatives to antibiotic feed additives, we compared the efficacy of two doses of Scrophularia striata extract [S. striata-Low at 40 and S. striata-High at 80 mg g-1 dry matter (DM)] with monensin (monensin) and a negative control in the modulation of rumen fermentation, methane production and microbial abundance in vitro. Microbes were investigated using qPCR and 16S rRNA targeted sequencing. Data showed that the addition of S. striata increased production of total short chain fatty acids (SCFA) in comparison to both monensin and control (P = 0.04). The addition of S. striata increased acetate production, and increased propionate at the higher dosage (P < 0.001). Supplementation of S. striata lowered methane production (P < 0.001) compared to control but with no effect compared to monensin. Ammonia concentration decreased by 52% (P < 0.001) with S. striata-High supplementation (4.14 mmol L-1) compared to control, which was greater than that of monensin (36%). The diversity of rumen bacteria was reduced (P < 0.001) for monensin and S. striata for both the number of observed OTUs and the Chao1 index. Quantitative analysis of Protozoa showed a decrease in the monensin treatment (P = 0.05) compared to control. Archaea copy numbers decreased equally in both S. striata-High and monensin treatments compared to the control group. Supplementation with S. striata increased relative abundances of Fibrobacteres (P < 0.001) and Planctomycetes (P = 0.001) in comparison to both the control and monensin treatments. Significant negative correlations were observed between the abundances of Bacteroides, Fusobacterium, and Succinivibrio genera and methane (r > -0.71; P <= 0.001). The abundance of Fibrobacter genera and total SCFA (r = 0.86), acetate (r = 0.75), and valerate (r = -0.51; P < 0.001) correlated positively. These results suggest that S. striata supplementation at 80 mg g-1 DM inclusion, similar to monensin, supports rumen fermentation, lowers methane and ammonia production. However, S. striata supported rumen fermentation toward higher total SCFA and propionate production, while unlike monensin still supported a diverse rumen microbiome and an increase in cellulolytic bacteria such as Fibrobacter. PMID- 30283416 TI - FLIM-MAP: Gene Context Based Identification of Functional Modules in Bacterial Metabolic Pathways. AB - Prediction of functional potential of bacteria can only be ascertained by the accurate annotation of its metabolic pathways. Homology based methods decipher metabolic gene content but ignore the fact that homologs of same protein can function in different pathways. Therefore, mere presence of all constituent genes in an organism is not sufficient to indicate a pathway. Contextual occurrence of genes belonging to a pathway on the bacterial genome can hence be exploited for an accurate estimation of functional potential of a bacterium. In this communication, we present a novel annotation resource to accurately identify pathway presence by using gene context. Our tool FLIM-MAP (Functionally Important Modules in bacterial Metabolic Pathways) predicts biologically relevant functional units called 'GCMs' (Gene Context based Modules) from a given metabolic reaction network. We benchmark the accuracy of our tool on amino acids and carbohydrate metabolism pathways. PMID- 30283417 TI - Using 'Omic Approaches to Compare Temporal Bacterial Colonization of Lolium perenne, Lotus corniculatus, and Trifolium pratense in the Rumen. AB - Understanding rumen plant-microbe interactions is central for development of novel methodologies allowing improvements in ruminant nutrient use efficiency. This study investigated rumen bacterial colonization of fresh plant material and changes in plant chemistry over a period of 24 h period using three different fresh forages: Lolium perenne (perennial ryegrass; PRG), Lotus corniculatus (bird's foot trefoil; BFT) and Trifolium pratense (red clover; RC). We show using 16S rRNA gene ion torrent sequencing that plant epiphytic populations present pre incubation (0 h) were substantially different to those attached post incubations in the presence of rumen fluid on all forages. Thereafter primary and secondary colonization events were evident as defined by changes in relative abundances of attached bacteria and changes in plant chemistry, as assessed using Fourier transform infrared (FTIR) spectroscopy. For PRG colonization, primary colonization occurred for up to 4 h and secondary colonization from 4 h onward. The changes from primary to secondary colonization occurred significantly later with BFT and RC, with primary colonization being up to 6 h and secondary colonization post 6 h of incubation. Across all 3 forages the main colonizing bacteria present at all time points post-incubation were Prevotella, Pseudobutyrivibrio, Ruminococcus, Olsenella, Butyrivibrio, and Anaeroplasma (14.2, 5.4, 1.9, 2.7, 1.8, and 2.0% on average respectively), with Pseudobutyrivibrio and Anaeroplasma having a higher relative abundance during secondary colonization. Using CowPI, we predict differences between bacterial metabolic function during primary and secondary colonization. Specifically, our results infer an increase in carbohydrate metabolism in the bacteria attached during secondary colonization, irrespective of forage type. The CowPI data coupled with the FTIR plant chemistry data suggest that attached bacterial function is similar irrespective of forage type, with the main changes occurring between primary and secondary colonization. These data suggest that the sward composition of pasture may have major implications for the temporal availability of nutrients for animal. PMID- 30283418 TI - Dosing Regimen of Enrofloxacin Impacts Intestinal Pharmacokinetics and the Fecal Microbiota in Steers. AB - Objective: The intestinal concentrations of antimicrobial drugs that select for resistance in fecal bacteria of cattle are poorly understood. Our objective was to associate active drug concentrations in the intestine of steers with changes in the resistance profile and composition of the fecal microbiome. Methods: Steers were administered either a single dose (12.5 mg/kg) or 3 multiple doses (5 mg/kg) of enrofloxacin subcutaneously every 24 h. Enrofloxacin and ciprofloxacin concentrations in intestinal fluid were measured over 96 h, and the abundance and MIC of E. coli in culture and the composition of the fecal microbiota by 16S rRNA gene sequencing were assessed over 192 h after initial treatment. Results: Active drug concentrations in the ileum and colon exceeded plasma and interstitial fluid concentrations, but were largely eliminated by 48 h after the last dose. The concentration of E. coli in the feces significantly decreased during peak drug concentrations, but returned to baseline by 96 h in both groups. The median MIC of E. coli isolates increased for 24 h in the single dose group, and for 48 h in the multiple dose group. The median MIC was higher in the multiple dose group when compared to the single dose group starting 12 h after the initial dose. The diversity of the fecal microbiota did not change in either treatment group, and taxa-specific changes were primarily seen in phyla commonly associated with the rumen. Conclusions: Both dosing regimens of enrofloxacin achieve high concentrations in the intestinal lumen, and the rapid elimination mitigates long term impacts on fecal E. coli resistance and the microbiota. PMID- 30283419 TI - Changes in the Intestine Microbial, Digestive, and Immune-Related Genes of Litopenaeus vannamei in Response to Dietary Probiotic Clostridium butyricum Supplementation. AB - The intestine barrier serves as the front-line defense in shrimp. Clostridium butyricum (CB) can produce butyric acid that provides energy for the intestine epithelial cells of the host. However, the effects of dietary CB on the intestine microbiome and the digestion and immunity of the host is not clear. In this study, we therefore investigated the composition and metabolic activity of the intestine microbiome, and digestive and immune-related gene expression in Litopenaeus vannamei fed with diets containing different levels of CB: basal diet (control), 2.5 * 109 CFU kg-1 diet (CB1), 5.0 * 109 CFU kg-1 diet (CB2), and 1.0 * 1010 CFU kg-1 diet (CB3) for 56 days. Dietary CB altered the composition of the intestine microbiome. Specifically, the dominant bacterial phylum Proteobacteria was enriched in the CB3 group and weakened in the CB1 and CB2 groups. The Bacteroidetes was enriched in the CB1 and CB2 groups and weakened in the CB3 group. The Firmicutes was enriched in all three CB groups. At the genus level, the potential pathogen (Desulfovibrio and Desulfobulbus) were weakened, and beneficial bacteria (Bacillus, Clostridium, Lachmoclostridium, Lachnospiraceae, and Lactobacillus) were enriched in response to dietary CB; these might contribute to the expression of the host digestive genes (alpha-amylase, lipase, trypsin, fatty acid-binding protein, and fatty acid synthase) and immune-related genes (prophenoloxidase, lipopolysaccharide and beta-1,3-glucan binding protein, lysozyme, crustin, and superoxide dismutase). Additionally, CB enhanced the bacterial metabolism, especially that of carbohydrates, polymers, amino acids, carboxylic acids, and amines. These results revealed that dietary CB had a beneficial effect on the intestine health of L. vannamei by modulating the composition of the intestine microbiome, enhancing the microbial metabolism activity, and promoting the digestion and immunity of the host. The optimal dietary supplementation dosage was found to be 5.0 * 109 CFU kg-1 in the diet. PMID- 30283420 TI - Cucumber (Cucumis sativus L.) Seedling Rhizosphere Trichoderma and Fusarium spp. Communities Altered by Vanillic Acid. AB - Root exudates mediate soil microbiome composition and diversity, which might further influence plant development and health. Vanillic acid from root exudates is usually referred as autotoxin of cucumber, however, how vanillic acid affect soil microbial community diversities and abundances remains unclear. In this study, vanillic acid (VA; 0.02, 0.05, 0.1, and 0.2 MUmol g-1 soil) was applied to soil every other day for a total of five applications. We used Illumina MiSeq sequencing, quantitative PCR (qPCR) and PCR-denaturing gradient gel electrophoresis (PCR-DGGE) to test the effects of VA on the total fungi community composition as well as the Trichoderma and Fusarium spp. community abundances and structures in the cucumber rhizosphere. Illumina MiSeq sequencing showed that VA (0.05 MUmol g-1 soil) increased the relative abundance of the fungal phylum Basidiomycota while decreasing the relative abundance of Ascomycota (P < 0.05), and not altered the diversity of the soil fungal community. VA (0.05 MUmol g-1 soil) also increased the relative abundances of the fungal genera with plant pathogens, such as Conocybe and Spizellomyces spp.(P < 0.05). A qPCR analysis showed that VA (0.05 to 0.2 MUmol g-1 soil) exerted promoting effects on Trichoderma spp. community abundance and stimulated Fusarium spp. abundance at low concentrations (0.02 to 0.05 MUmol g-1 soil) but inhibited it at high concentrations (0.1 to 0.2 MUmol g-1 soil). The PCR-DGGE analysis showed that all concentrations of VA altered the community structures of Trichoderma spp. and that the application of VA (0.02 and 0.05 MUmol g-1 soil) changed the band number and the Shannon-Wiener index of the Fusarium spp. community. This study demonstrated that VA changed the total fungal community in the cucumber seedling rhizosphere and that the Trichoderma and Fusarium spp. communities showed different responses to VA. PMID- 30283421 TI - Microbial Community Composition in Take-All Suppressive Soils. AB - Gaeumannomyces graminis var. tritici (Ggt) is the main soilborne factor that affects wheat production around the world. Recently we reported the occurrence of six suppressive soils in monoculture areas from indigenous "Mapuche" communities, and evidenced that the suppression relied on the biotic component of those soils. Here, we compare the rhizosphere and endosphere microbial community structure (total bacteria, actinomycetes, total fungi, and ascomycetes) of wheat plants grown in suppressive and conducive soils. Our results suggested that Ggt suppression could be mediated mostly by bacterial endophytes, rather than rhizosphere microorganisms, since the community structure was similar in all suppressive soils as compared with conducive. Interestingly, we found that despite the lower incidence of take-all disease in suppressive soils, the Ggt concentration in roots was not significantly reduced in all suppressive soils compared to those growing in conducive soil. Therefore, the disease suppression is not always related to a reduction of the pathogen biomass. Furthermore, we isolated endophytic bacteria from wheat roots growing in suppressive soils. Among them we identified Serratia spp. and Enterobacter spp. able to inhibit Ggt growth in vitro. Since the disease, but not always pathogen amount, was reduced in the suppressive soils, we propose that take all disease suppressiveness is not only related to direct antagonism to the pathogen. PMID- 30283422 TI - Chinese Black Truffle (Tuber indicum) Alters the Ectomycorrhizosphere and Endoectomycosphere Microbiome and Metabolic Profiles of the Host Tree Quercus aliena. AB - Truffles are one group of the most famous ectomycorrhizal fungi in the world. There is little information on the ecological mechanisms of truffle ectomycorrhizal synthesis in vitro. In this study, we investigated the ecological effects of Tuber indicum - Quercus aliena ectomycorrhizal synthesis on microbial communities in the host plant roots and the surrounding soil using high throughput sequencing and on the metabolic profiles of host plant roots using metabolomics approaches. We observed an increase in the diversity and richness of prokaryotic communities and a decrease in richness of fungal communities in the presence of T. indicum. The microbial community structures in the host roots and the surrounding soil were altered by ectomycorrhizal synthesis in the greenhouse. Bacterial genera Pedomicrobium, Variibacter, and Woodsholea and fungal genera Aspergillus, Phaeoacremonium, and Pochonia were significantly more abundant in ectomycorhizae and the ectomycorrhizosphere soil compared with the corresponding T. indicum-free controls (P < 0.05). Truffle-colonization reduced the abundance of some fungal genera surrounding the host tree, such as Acremonium, Aspergillus, and Penicillium. Putative prokaryotic metabolic functions and fungal functional groups (guilds) were also differentiated by ectomycorrhizal synthesis. The ectomycorrhizal synthesis had great impact on the measured soil physicochemical properties. Metabolic profiling analysis uncovered 55 named differentially abundant metabolites between the ectomycorhizae and the control roots, including 44 upregulated and 11 downregulated metabolites. Organic acids and carbohydrates were two major upregulated metabolites in ectomycorhizae, which were found formed dense interactions with other metabolites, suggesting their crucial roles in sustaining the metabolic functions in the truffle ectomycorrhization system. This study revealed the effects of truffle-colonization on the metabolites of ectomycorrhiza and illustrates an interactive network between truffles, the host plant, soil and associated microbial communities, shedding light on understanding the ecological effects of truffles. PMID- 30283423 TI - A New Freshwater Cyanosiphovirus Harboring Integrase. AB - Pelagic cyanobacteria are key players in the functioning of aquatic ecosystems, and their viruses (cyanophages) potentially affect the abundance and composition of cyanobacterial communities. Yet, there are few well-described freshwater cyanophages relative to their marine counterparts, and in general, few cyanosiphoviruses (family Siphoviridae) have been characterized, limiting our understanding of the biology and the ecology of this prominent group of viruses. Here, we characterize S-LBS1, a freshwater siphovirus lytic to a phycoerythrin rich Synechococcus isolate (Strain TCC793). S-LBS1 has a narrow host range, a burst size of ~400 and a relatively long infecting step before cell lysis occurs. It has a dsDNA 34,641 bp genome with putative genes for structure, DNA packing, lysis, replication, host interactions, DNA repair and metabolism. S-LBS1 is similar in genome size, genome architecture, and gene content, to previously described marine siphoviruses also infecting PE-rich Synechococcus, e.g., S-CBS1 and S-CBS3. However, unlike other Synechococcus phages, S-LBS1 encodes an integrase, suggesting its ability to establish lysogenic relationships with its host. Sequence recruitment from viral metagenomic data showed that S-LBS1-like viruses are diversely present in a wide range of aquatic environments, emphasizing their potential importance in controlling and structuring Synechococcus populations. A comparative analysis with 16 available sequenced cyanosiphoviruses reveals the absence of core genes within the genomes, suggesting high degree of genetic variability in siphoviruses infecting cyanobacteria. It is likely that cyanosiphoviruses have evolved as distinct evolutionary lineages and that adaptive co-evolution occurred between these viruses and their hosts (i.e., Synechococcus, Prochlorococcus, Nodularia, and Acaryochloris), constituting an important driving force for such phage diversification. PMID- 30283424 TI - Impact of Distribution and Network Flushing on the Drinking Water Microbiome. AB - We sampled the tap water of seven unique, full-scale drinking water distribution systems at different locations as well as the corresponding treatment plant effluents to evaluate the impact of distribution and the potential presence of a core drinking water microbiome. The water was also sampled during network flushing to examine its effect on the microbial ecology. While a core microbiome dominated by Gammaproteobacteria was found using 16S rRNA gene pyrosequencing, an increase in biomass was detected in the networks, especially during flushing. Water age did not significantly impact the microbiology. Irrespective of differences in treatment plants, tap water bacterial communities in the distinct networks converged and highly resembled the flushed water communities. Piping biofilm and sediment communities therefore largely determine the final tap water microbial quality, attenuating the impact of water source and treatment strategy and highlighting the fundamental role of local physicochemical conditions and microbial processes within infrastructure micro-niches. PMID- 30283425 TI - Characterizing the Human Mycobiota: A Comparison of Small Subunit rRNA, ITS1, ITS2, and Large Subunit rRNA Genomic Targets. AB - Interest in the human microbiome has increased dramatically in the last decade. However, much of this research has focused on bacteria, while the composition and roles of their fungal counterparts remain less understood. Furthermore, a variety of methodological approaches have been applied, and the comparability between studies is unclear. This study compared four primer pairs targeting the small subunit (SSU) rRNA (18S), ITS1, ITS2, and large subunit (LSU) rRNA (26S) genomic regions for their ability to accurately characterize fungal communities typical of the human mycobiota. All four target regions of 21 individual fungal mock community taxa were capable of being amplified adequately and sequenced. Mixed mock community analyses revealed marked variability in the ability of each primer pair to accurately characterize a complex community. ITS target regions outperformed LSU and SSU. Of the ITS regions, ITS1 failed to generate sequences for Yarrowia lipolytica and all three Malassezia species when in a mixed community. These findings were further supported in studies of human sinonasal and mouse fecal samples. Based on these analyses, previous studies using ITS1, SSU, or LSU markers may omit key taxa that are identified by the ITS2 marker. Of methods commonly used in human mycobiota studies to date, we recommend selection of the ITS2 marker. Further investigation of more recently developed fungal primer options will be essential to ultimately determine the optimal methodological approach by which future human mycobiota studies ought to be standardized. PMID- 30283427 TI - Microbial Inoculants for Improving Crop Quality and Human Health in Africa. AB - Current agricultural practices depend heavily on chemical inputs (such as fertilizers, pesticides, herbicides, etc.) which, all things being equal cause a deleterious effect on the nutritional value of farm product and health of farm workers and consumers. Excessive and indiscriminate use of these chemicals have resulted in food contamination, weed and disease resistance and negative environmental outcomes which together have a significant impact on human health. Application of these chemical inputs promotes the accumulation of toxic compounds in soils. Chemical compounds are absorbed by most crops from soil. Several synthetic fertilizers contain acid radicals, such as hydrochloride and sulfuric radicals, and hence increase the soil acidity and adversely affect soil and plant health. Highly recalcitrant compounds can also be absorbed by some plants. Continuous consumption of such crops can lead to systematic disorders in humans. Quite a number of pesticides and herbicides have carcinogenicity potential. The increasing awareness of health challenges as a result of consumption of poor quality crops has led to a quest for new and improved technologies of improving both the quantity and quality of crop without jeopardizing human health. A reliable alternative to the use of chemical inputs is microbial inoculants that can act as biofertilizers, bioherbicide, biopesticides, and biocontrol agents. Microorganisms are able to carry out the plant growth promotion, pest and disease and weed control. Microbial inoculants are beneficiary microorganisms applied to either the soil or the plant in order to improve productivity and crop health. Microbial inoculants are natural-based products being widely used to control pests and improve the quality of the soil and crop, and hence human health. Microbial inoculants involve a blend of microorganisms that work with the soil and the soil life to improve soil fertility and health and by extension improve human health. Microbial inoculants have the ability to minimize the negative impact of chemical input and consequently increase the quantity and quality of farm produce. Microbial inoculants are environmental-friendly and deliver plant nutrients to plants in a more sustainable manner. Microbial inoculants can help reduce chemical fertilizer application. Microbial inoculants could include bacteria, fungi and algae. This research summarizes the impact of agricultural chemical inputs on human health. The contribution of microbial inoculants in sustainable maintenance of human health will be expatiated. Advances in microbial inoculants and technology and strategies to explore this natural, user friendly biological resource for sustainable maintenance of plant health will be discussed. PMID- 30283426 TI - A Class 1 Histone Deacetylase as Major Regulator of Secondary Metabolite Production in Aspergillus nidulans. AB - An outstanding feature of filamentous fungi is their ability to produce a wide variety of small bioactive molecules that contribute to their survival, fitness, and pathogenicity. The vast collection of these so-called secondary metabolites (SMs) includes molecules that play a role in virulence, protect fungi from environmental damage, act as toxins or antibiotics that harm host tissues, or hinder microbial competitors for food sources. Many of these compounds are used in medical treatment; however, biosynthetic genes for the production of these natural products are arranged in compact clusters that are commonly silent under growth conditions routinely used in laboratories. Consequently, a wide arsenal of yet unknown fungal metabolites is waiting to be discovered. Here, we describe the effects of deletion of hosA, one of four classical histone deacetylase (HDAC) genes in Aspergillus nidulans; we show that HosA acts as a major regulator of SMs in Aspergillus with converse regulatory effects depending on the metabolite gene cluster examined. Co-inhibition of all classical enzymes by the pan HDAC inhibitor trichostatin A and the analysis of HDAC double mutants indicate that HosA is able to override known regulatory effects of other HDACs such as the class 2 type enzyme HdaA. Chromatin immunoprecipitation analysis revealed a direct correlation between hosA deletion, the acetylation status of H4 and the regulation of SM cluster genes, whereas H3 hyper-acetylation could not be detected in all the upregulated SM clusters examined. Our data suggest that HosA has inductive effects on SM production in addition to its classical role as a repressor via deacetylation of histones. Moreover, a genome wide transcriptome analysis revealed that in addition to SMs, expression of several other important protein categories such as enzymes of the carbohydrate metabolism or proteins involved in disease, virulence, and defense are significantly affected by the deletion of HosA. PMID- 30283428 TI - In vitro Probiotic Potential and Anti-cancer Activity of Newly Isolated Folate Producing Streptococcus thermophilus Strains. AB - Most probiotic strains commercially available today are lactic acid bacteria. Within this functional group, Streptococcus thermophilus is a thermophilic species widely used as starter culture for a huge number of dairy products. Besides being rapid acidifiers, many S. thermophilus strains are able to produce and release folate during growth but, unfortunately, they are seriously impaired during passage through the human gastrointestinal tract. In this work, we studied eight S. thermophilus strains isolated from dairy environments in Italy, which already had shown good technological properties, to evaluate their possible probiotic potential and cytotoxicity against cancer cells in vitro. All strains were also evaluated for some health-related properties such as susceptibility to most common antibiotics, hemolytic activity, resistance to simulated gastrointestinal conditions, bile salts hydrolytic activity, production of folate, adhesion to HT-29 human colorectal adenocarcinoma cells and cytotoxic activity against cancer cells and production of biogenic amines. Results revealed that two fast acidifying S. thermophilus strains were found to possess in vitro probiotic properties along with anticancer activity and production of folate. These properties resulted similar and, in some cases, superior to those of Lactobacillus rhamnosus GG, a well-known commercial probiotic strain. These findings encourage further in vivo studies to evaluate the actual health benefits of these strains on the human host. PMID- 30283429 TI - Occurrence, Antibiotic Resistance, and Population Diversity of Listeria monocytogenes Isolated From Fresh Aquatic Products in China. AB - Listeria monocytogenes is an important Gram-positive foodborne pathogen. However, limited information is available on the comprehensive investigation and potential risk of L. monocytogenes in fresh aquatic products, which are popular to consumers in China. This study aimed to determine the occurrence, virulence profiles, and population diversity of L. monocytogenes isolated from aquatic products in China. In total, 846 aquatic product samples were collected between July 2011 and April 2016 from 43 cities in China. Approximately 7.92% (67/846) aquatic product samples were positive for L. monocytogenes, 86.57% positive samples ranged from 0.3 to 10 MPN/g, whereas 5.97% showed over 110 MPN/g by the Most Probable Number method, which included two samples of products intended to be eaten raw. Serogroups I.1 (serotype 1/2a), I.2 (serotype 1/2b), and III (serotype 4c) were the predominant serogroups isolated, whereas serogroup II.1 (serotype 4b) was detected at much lower frequencies. Examination of antibacterial resistance showed that nine antibacterial resistance profiles were exhibited in 72 isolates, a high level susceptibility of 16 tested antibiotics against L. monocytogenes were observed, indicating these common antibacterial agents are still effective for treating L. monocytogenes infection. Multilocus sequence typing revealed that ST299, ST87, and ST8 are predominant in aquatic products, indicating that the rare ST299 (serotype 4c) may have a special ecological niche in aquatic products and associated environments. Except llsX and ptsA, the 72 isolates harbor nine virulence genes (prfA, actA, hly, plcA, plcB, iap, mpl, inlA, and inlB), premature stop codons (PMSCs) in inlA were found in four isolates, three of which belonged to ST9. A novel PMSC was found in 2929-1LM with a nonsense mutation at position 1605 (TGG->TGA). All ST87 isolates harbored the ptsA gene, whereas 8 isolates (11.11%) carried the llsX gene, and mainly belonged to ST1, ST3, ST308, ST323, ST330, and ST619. Taken together, these results first reported potential virulent L. monocytogenes isolates (ST8 and ST87) were predominant in aquatic products which may have implications for public health in China. It is thus necessary to perform continuous surveillance for L. monocytogenes in aquatic products in China. PMID- 30283430 TI - Detection of Viral Pathogens With Multiplex Nanopore MinION Sequencing: Be Careful With Cross-Talk. AB - Metagenomic sequencing with the Oxford Nanopore MinION sequencer offers potential for point-of-care testing of infectious diseases in clinical settings. To improve cost-effectiveness, multiplexing of several, barcoded samples upon a single flow cell will be required during sequencing. We generated a unique sequencing dataset to assess the extent and source of cross barcode contamination caused by multiplex MinION sequencing. Sequencing libraries for three different viruses, including influenza A, dengue, and chikungunya, were prepared separately and sequenced on individual flow cells. We also pooled the respective libraries and performed multiplex sequencing. We identified 0.056% of total reads in the multiplex sequencing data that were assigned to incorrect barcodes. Chimeric reads were the predominant source of this error. Our findings highlight the need for careful filtering of multiplex sequencing data before downstream analysis, and the trade-off between sensitivity and specificity that applies to the barcode demultiplexing methods. PMID- 30283431 TI - Species Pervasiveness Within the Group of Coagulase-Negative Staphylococci Associated With Meat Fermentation Is Modulated by pH. AB - During spontaneous meat fermentations, Staphylococcus equorum, Staphylococcus saprophyticus, and Staphylococcus xylosus are generally the most prevailing species within the communities of coagulase-negative staphylococci (CNS). There is an interest to introduce CNS isolates from artisan-style spontaneous meat fermentations as starter cultures in more industrialized processes, as to confer additional quality benefits. However, staphylococcal competitiveness within the meat matrix is affected by the processing conditions, which vary considerably among product types. A major factor of variability relates to the intensity of acidification, driven by the concentration of added carbohydrates. The effect of pH on CNS prevalence was studied in both a mince-based meat fermentation model and in fermented sausages produced on pilot scale. Roughly, from all experiments combined, it appeared that a pH of 5.3 corresponded with a breakpoint for CNS selection. Above this value, a general prevalence by S. xylosus was found, even overruling the addition of starter cultures consisting of S. equorum and S. saprophyticus strains. At pH values below 5.3, S. xylosus was also accompanied by S. equorum (following a mild pH drop) and S. saprophyticus (following a stronger pH drop). Still, addition of starter cultures affected the volatile profile compared to the control batch, even if those starter cultures were not able to dominate during the ripening process. This study nonetheless provides a warning for an overly confident use of specific CNS species as starter cultures, especially when in a given processing context the prevailing conditions do not allow superior growth compared to the CNS from the background microbiota. PMID- 30283432 TI - Alterations of the Gut Microbiome Associated With the Treatment of Hyperuricaemia in Male Rats. AB - Hyperuricaemia is an important risk factor for many diseases including gout, hypertension, and type II diabetes. The gut microbiota is associated with hyperuricaemia and has also been demonstrated to play significant roles in the effects of drug therapy. This study used Illumina MiSeq sequencing to explore alterations of the gut microbiome associated with allopurinol and benzbromarone treatment in the male rat with hyperuricaemia. After drug treatment, both allopurinol and benzbromarone caused an increase of the genera Bifidobacterium and Collinsella and a decrease of the genera Adlercreutzia and Anaerostipes. In addition, allopurinol and benzbromarone caused respective unique changes in genera. The genera Bilophila, Morganella, and Desulfovibrio specifically decreased due to allopurinol treatment. Decreased Butyricimonas and Ruminococcus and increased Proteus were caused by benzbromarone treatment. The PICRUST analysis indicated that allopurinol renovated the disorder of nucleotide metabolism and benzbromarone renovated the disorder of lipid metabolism in the gut microbiota of male rats with hyperuricaemia. These findings demonstrated that the gut microbiota may be altered by the treatment of hyperuricaemia with allopurinol and benzbromarone in male rats. Such alterations of the gut microbiota could be considered as indicators of the effectiveness of drug therapy. PMID- 30283433 TI - Bicarbonate Inhibits Bacterial Growth and Biofilm Formation of Prevalent Cystic Fibrosis Pathogens. AB - We investigated the effects of bicarbonate on the growth of several different bacteria as well as its effects on biofilm formation and intracellular cAMP concentration in Pseudomonas aeruginosa. Biofilm formation was examined in 96 well plates, with or without bicarbonate. The cAMP production of bacteria was measured by a commercial assay kit. We found that NaHCO3 (100 mmol l-1) significantly inhibited, whereas NaCl (100 mmol l-1) did not influence the growth of planktonic bacteria. MIC and MBC measurements indicated that the effect of HCO3- is bacteriostatic rather than bactericidal. Moreover, NaHCO3 prevented biofilm formation as a function of concentration. Bicarbonate and alkalinization of external pH induced a significant increase in intracellular cAMP levels. In conclusion, HCO3- impedes the planktonic growth of different bacteria and impedes biofilm formation by P. aeruginosa that is associated with increased intracellular cAMP production. These findings suggest that aerosol inhalation therapy with HCO3- solutions may help improve respiratory hygiene in patients with cystic fibrosis and possibly other chronically infected lung diseases. PMID- 30283434 TI - New Vaccine Technologies to Combat Outbreak Situations. AB - Ever since the development of the first vaccine more than 200 years ago, vaccinations have greatly decreased the burden of infectious diseases worldwide, famously leading to the eradication of small pox and allowing the restriction of diseases such as polio, tetanus, diphtheria, and measles. A multitude of research efforts focuses on the improvement of established and the discovery of new vaccines such as the HPV (human papilloma virus) vaccine in 2006. However, radical changes in the density, age distribution and traveling habits of the population worldwide as well as the changing climate favor the emergence of old and new pathogens that bear the risk of becoming pandemic threats. In recent years, the rapid spread of severe infections such as HIV, SARS, Ebola, and Zika have highlighted the dire need for global preparedness for pandemics, which necessitates the extremely rapid development and comprehensive distribution of vaccines against potentially previously unknown pathogens. What is more, the emergence of antibiotic resistant bacteria calls for new approaches to prevent infections. Given these changes, established methods for the identification of new vaccine candidates are no longer sufficient to ensure global protection. Hence, new vaccine technologies able to achieve rapid development as well as large scale production are of pivotal importance. This review will discuss viral vector and nucleic acid-based vaccines (DNA and mRNA vaccines) as new approaches that might be able to tackle these challenges to global health. PMID- 30283436 TI - Essential Domain-Dependent Roles Within Soluble IgG for in vivo Superantigen Properties of Staphylococcal Protein A: Resolving the B-Cell Superantigen Paradox. AB - Staphylococcus aureus is a common commensal and frequent opportunistic pathogen that causes invasive infections that often recur. Co-evolution with the host has led to the development of toxins that affect diverse immune cell types. Recent reports have highlighted the contributions of staphylococcal protein A (SpA). This small oligomeric secreted protein contains 4-5 homologous domains with two distinct immunoglobulin-binding sites; one for IgG Fc domains, while a separate site binds an evolutionarily conserved surface on Fab encoded by VHIII clan related genes. The Fab-binding site has been implicated in in vivo supraclonal VHIII-BCR targeted B-cell depletion by an activation induced death pathway. Yet the concept of a superantigen for B lymphocytes poses a seeming paradox. Unlike TCR that are expressed only in a membrane-associated form, BCR are expressed in both a membrane BCR form and in secreted Ig forms, which permeate virtually every part of the body at high levels. We therefore asked, why circulating immunoglobulin do not block the superantigen properties of SpA? Herein, we show that soluble IgG molecules are not in vivo inhibitors of these B-cell superantigen effects but are instead essential for potentiating these properties. We also show that the Fc subclass of circulating IgG is an indirect critical determinant of the B-cell superantigen effect. In contrast, host FcgammaR and complement are not required for SpA mediated in vivo B-cell depletion. Unexpectedly, after VHIII-IgG2a pretreatment SpA challenge resulted in fatal anaphylactic reactions, which we speculate may have involved FcgammaR interactions with mast cells and basophils. Cumulatively, our findings illuminate a cunning and potent molecular strategy by which a bacterial toxin effectively confounds the contributions of host B-lymphocytes to immune defenses. PMID- 30283437 TI - Aryl Hydrocarbon Receptor Promotes IL-10 Expression in Inflammatory Macrophages Through Src-STAT3 Signaling Pathway. AB - The aryl hydrocarbon receptor (AhR) is an important immune regulator with a role in inflammatory response. However, the role of AhR in IL-10 production by inflammatory macrophages is currently unknown. In this study, we investigated LPS induced IL-10 expression in macrophages from AhR-KO mice and AhR-overexpressing RAW264.7 cells. AhR was highly expressed after LPS stimulation through NF-kappaB pathway. Loss of AhR resulted in reduced IL-10 expression in LPS-induced macrophages. Moreover, the IL-10 expression was elevated in LPS-induced AhR overexpressing RAW264.7 cells. Maximal IL-10 expression was dependent on an AhR non-genomic pathway closely related to Src and STAT3. Furthermore, AhR-associated Src activity was responsible for tyrosine phosphorylation of STAT3 and IL-10 expression by inflammatory macrophages. Adoptive transfer of AhR-expressing macrophages protected mice against LPS-induced peritonitis associated with high IL-10 production. In conclusion, we identified the AhR-Src-STAT3-IL-10 signaling pathway as a critical pathway in the immune regulation of inflammatory macrophages, It suggests that AhR may be a potential therapeutic target in immune response. PMID- 30283438 TI - Inflammatory Endotypes and Microbial Associations in Chronic Rhinosinusitis. AB - A complex mix of inflammatory and microbial associations underscores the chronic inflammatory condition chronic rhinosinusitis (CRS), and the etiology remains poorly understood. Recent work has begun to delineate between variants (endotypes) of CRS on the basis of inflammatory biomarkers. This study aimed to assess inflammatory patterns in CRS phenotypes, identify putative endotypes of CRS, and to assess inflammatory associations with the sinonasal microbiota. Ten cytokines and six inflammatory cell types were assessed in mucosal biopsies from 93 CRS subjects and 17 controls via cytometric bead array and immunohistochemical techniques. Putative endotypes were identified via cluster analysis of subjects on the basis of inflammatory markers and comorbidities including polyposis, asthma, and aspirin sensitivity. Finally, previously published bacterial data for this cohort were reanalyzed to evaluate associations with inflammatory markers and CRS subtypes. Inflammatory patterns were highly variable within standard CRS phenotypes. Cluster analysis identified eight subject clusters, with strong delineation on the basis of polyposis and asthma, but also subtle distinctions in inflammatory markers. An association was also identified between depletion of several "health-associated" bacterial taxa, reduced bacterial diversity and increased overall bacterial load, with markers of inflammation and clinical severity. This study contributes to ongoing efforts to define distinct endotypes of CRS on the basis of underlying inflammatory processes, and also offers compelling evidence of a link between bacterial community dysbiosis and inflammation in CRS. Further resolving the heterogeneity of CRS is vital to inform clinical management and personalized treatment approaches. PMID- 30283435 TI - A Potential Link Between Oxidative Stress and Endothelial-to-Mesenchymal Transition in Systemic Sclerosis. AB - Systemic sclerosis (SSc), an autoimmune disease that is associated with a number of genetic and environmental risk factors, is characterized by progressive fibrosis and microvasculature damage in the skin, lungs, heart, digestive system, kidneys, muscles, joints, and nervous system. These abnormalities are associated with altered secretion of growth factor and profibrotic cytokines, such as transforming growth factor-beta (TGF-beta), interleukin-4 (IL-4), platelet derived growth factor (PDGF), and connective-tissue growth factor (CTGF). Among the cellular responses to this proinflammatory environment, the endothelial cells phenotypic conversion into activated myofibroblasts, a process known as endothelial to mesenchymal transition (EndMT), has been postulated. Reactive oxygen species (ROS) might play a key role in SSs-associated fibrosis and vascular damage by mediating and/or activating TGF-beta-induced EndMT, a phenomenon that has been observed in other disease models. In this review, we identified and critically appraised published studies investigating associations ROS and EndMT and the presence of EndMT in SSc, highlighting a potential link between oxidative stress and EndMT in this condition. PMID- 30283439 TI - Toxoplasma Effector TgIST Targets Host IDO1 to Antagonize the IFN-gamma-Induced Anti-parasitic Response in Human Cells. AB - Toxoplasma gondii is an important human and animal pathogen that causes life threatening toxoplasmosis. Interferon-gamma (IFN-gamma) is critical for anti-T. gondii cell-autonomous immunity in both humans and mice. To proliferate efficiently within the hosts, virulent strains of T. gondii can suppress IFN gamma-dependent immunity. During parasite infection, it is well-characterized that various virulence effectors are secreted to transcriptionally or post translationally target IFN-gamma-inducible GTPases, which are essential for anti parasite responses in mice. However, the role of IFN-gamma-inducible GTPases in anti-T. gondii responses in human cells is controversial since they are non functional or absent in humans. Instead, IFN-gamma-induced tryptophan degradation by indole-2,3-dioxygenase (IDO) is important for the anti-T. gondii human response. To date, the T. gondii virulent mechanism targeting IDO in human cells remains elusive. Here we show that although humans possess two IDO isozymes, IDO1 and IDO2, human cells of various origins require IDO1 but not IDO2 for IFN-gamma induced cell-autonomous immunity to T. gondii. T. gondii secretes an effector TgIST to inhibit IDO1 mRNA expression. Taken together, the data suggests that T. gondii possesses virulence programs operated by TgIST to antagonize IFN-gamma induced IDO1-mediated anti-parasite cell-autonomous immunity in human cells. PMID- 30283441 TI - Decidual-Placental Immune Landscape During Syngeneic Murine Pregnancy. AB - Adaptive immune system, principally governed by the T cells-dendritic cells (DCs) nexus, is an essential mediator of gestational fetal tolerance and protection against infection. However, the exact composition and dynamics of DCs and T cell subsets in gestational tissues are not well understood. These are controlled in human physiology by a complex interplay of alloantigen distribution and presentation, cellular/humoral active and passive tolerance, hormones/chemokines/angiogenic factors and their gradients, systemic and local microbial communities. Reductive discrimination of these factors in physiology and pathology of model systems and humans requires simplification of the model and increased resolution of interrogative technologies. As a baseline, we have studied the gestational tissue dynamics in the syngeneic C57BL/6 mice, as the simplest immunological environment, and focused on validating the approach to increased data density and computational analysis pipeline afforded by highly polychromatic flow cytometry and machine learning interpretation. We mapped DC and T cell subsets, and comprehensively examined their maternal (decidual)-fetal (placental) interface dynamics. Both frequency and composition of decidual DCs changed across gestation, with a dramatic increase in myeloid DCs in early pregnancy, and exclusion of plasmacytoid DCs. CD4+ T cells, in contrast, were lower at all gestational ages and an unusual CD4-CD8-TCRalphabeta+group was prominent at mid-pregnancy. Dimensionality reduction with machine learning-aided clustering revealed that CD4-CD8- T cells were phenotypically different from CD4+ and CD8+ T cells. Additionally, divergence between maternal decidual and fetal placental compartment was prominent, with absence of DCs from the placenta, but not decidua or embryo. These results provide a novel framework and a syngeneic baseline on which the specific role of alloantigen/tolerance, polymicrobial environment, and models of pregnancy pathology can be precisely modeled and analyzed. PMID- 30283440 TI - The CBM-opathies-A Rapidly Expanding Spectrum of Human Inborn Errors of Immunity Caused by Mutations in the CARD11-BCL10-MALT1 Complex. AB - The caspase recruitment domain family member 11 (CARD11 or CARMA1)-B cell CLL/lymphoma 10 (BCL10)-MALT1 paracaspase (MALT1) [CBM] signalosome complex serves as a molecular bridge between cell surface antigen receptor signaling and the activation of the NF-kappaB, JNK, and mTORC1 signaling axes. This positions the CBM complex as a critical regulator of lymphocyte activation, proliferation, survival, and metabolism. Inborn errors in each of the CBM components have now been linked to a diverse group of human primary immunodeficiency diseases termed "CBM-opathies." Clinical manifestations range from severe combined immunodeficiency to selective B cell lymphocytosis, atopic disease, and specific humoral defects. This surprisingly broad spectrum of phenotypes underscores the importance of "tuning" CBM signaling to preserve immune homeostasis. Here, we review the distinct clinical and immunological phenotypes associated with human CBM complex mutations and introduce new avenues for targeted therapeutic intervention. PMID- 30283442 TI - CD8+ Resident Memory T Cells and Viral Infection. AB - Tissue-resident memory T (Trm) cells are a subset of recently identified memory T cells that mainly reside and serve as sentinels in non-lymphoid peripheral tissues. Unlike the well-characterized circulating central memory T (Tcm) cells and effector memory T (Tem) cells, Trm cells persist in the tissues, do not recirculate into blood, and offer immediate protection against pathogens upon reinfection. In this review, we focus on CD8+ Trm cells and briefly introduce their characteristics, development, maintenance, and function during viral infection. We also discuss some unresolved problems, such as how CD8+ Trm cells adapt to the local tissue microenvironment, how Trm cells interact with other immune cells during their development and maintenance, and the mechanisms by which CD8+ Trm cells confer immune protection. We believe that a better understanding of these problems is of great clinical and therapeutic value and may contribute to more effective vaccination and treatments against viral infection. PMID- 30283443 TI - Vibrio vulnificus RtxA Is a Major Factor Driving Inflammatory T Helper Type 17 Cell Responses in vitro and in vivo. AB - T helper type 17 (Th17) cells are a subset of pro-inflammatory T helper cells that mediate host defense and pathological inflammation. We have previously reported that host dendritic cells (DCs) infected with Vibrio vulnificus induce Th17 responses through the production of several pro-inflammatory cytokines, including interleukin (IL)-1beta and IL-6. V. vulnificus produces RTX toxin (RtxA), an important virulence factor that determines successful pathophysiology. In this study, we investigated the involvement of RtxA from V. vulnificus in Th17 cell induction through the activation and maturation of DCs. The increased expression of the DC surface marker CD40 caused by V. vulnificus wild-type infection was reduced by rtxA gene mutation in V. vulnificus. The mRNA and protein levels of Th17 polarization-related cytokines also decreased in V. vulnificus rtxA mutant-infected DCs. In addition, the co-culture of Th cells and DCs infected with rtxA mutant V. vulnificus resulted in reduction in DC-mediated Th17 responses. Th17 cell responses in the small intestinal lamina propria decreased in mice inoculated with V. vulnificus rtxA mutant as compared to those inoculated with the wild-type strain. These decreases in DC maturation, Th17 polarizing cytokine secretion, and Th17 responses attributed to rtxA mutation were restored following infection with the rtxA revertant strain. Furthermore, the mutation in the hlyU gene encoding the activator of rtxA1 gene reproduced the results observed with rtxA mutation. Taken together, V. vulnificus, by means of RtxA, induces inflammatory Th17 responses, which may be associated with adaptive responses of the host against V. vulnificus infection. PMID- 30283444 TI - RNA Structure-A Neglected Puppet Master for the Evolution of Virus and Host Immunity. AB - The central dogma of molecular biology describes the flow of genetic information from DNA to protein via an RNA intermediate. For many years, RNA has been considered simply as a messenger relaying information between DNA and proteins. Recent advances in next generation sequencing technology, bioinformatics, and non coding RNA biology have highlighted the many important roles of RNA in virtually every biological process. Our understanding of RNA biology has been further enriched by a number of significant advances in probing RNA structures. It is now appreciated that many cellular and viral biological processes are highly dependent on specific RNA structures and/or sequences, and such reliance will undoubtedly impact on the evolution of both hosts and viruses. As a contribution to this special issue on host immunity and virus evolution, it is timely to consider how RNA sequences and structures could directly influence the co evolution between hosts and viruses. In this manuscript, we begin by stating some of the basic principles of RNA structures, followed by describing some of the critical RNA structures in both viruses and hosts. More importantly, we highlight a number of available new tools to predict and to evaluate novel RNA structures, pointing out some of the limitations readers should be aware of in their own analyses. PMID- 30283445 TI - Neutrophil Activation in Acute Hemorrhagic Fever With Renal Syndrome Is Mediated by Hantavirus-Infected Microvascular Endothelial Cells. AB - Hantaviruses cause hemorrhagic fever with renal syndrome (HFRS) and hantavirus cardiopulmonary syndrome (HCPS) in humans. Both diseases are considered to be immunologically mediated but the exact pathological mechanisms are still poorly understood. Neutrophils are considered the first line of defense against invading microbes but little is still known of their role in virus infections. We wanted to study the role of neutrophils in HFRS using blood and tissue samples obtained from Puumala hantavirus (PUUV)-infected patients. We found that neutrophil activation products myeloperoxidase and neutrophil elastase, together with interleukin-8 (the major neutrophil chemotactic factor in humans), are strongly elevated in blood of acute PUUV-HFRS and positively correlate with kidney dysfunction, the hallmark clinical finding of HFRS. These markers localized mainly in the tubulointerstitial space in the kidneys of PUUV-HFRS patients suggesting neutrophil activation to be a likely component of the general immune response toward hantaviruses. We also observed increased levels of circulating extracellular histones at the acute stage of the disease supporting previous findings of neutrophil extracellular trap formation in PUUV-HFRS. Mechanistically, we did not find evidence for direct PUUV-mediated activation of neutrophils but instead primary blood microvascular endothelial cells acquired a pro-inflammatory phenotype and promoted neutrophil degranulation in response to PUUV infection in vitro. These results suggest that neutrophils are activated by hantavirus-infected endothelial cells and may contribute to the kidney pathology which determines the severity of HFRS. PMID- 30283446 TI - Gene Expression Analysis Identifies Novel Targets for Cervical Cancer Therapy. AB - Although there has been significant progress in prevention and treatment of cervical cancer, this malignancy is still a leading cause of cancer death for women. Anti-angiogenesis and immunotherapy approaches have been providing survival benefits, however, response rates and durability of response need to be improved. There is a clear need for combination therapies that increase effectiveness of these agents and further improve patient outcome. Previous studies have largely focused on gene expression and molecular pathways in untreated cervix cancer. The goal of this study was to evaluate cancer-specific molecular pathways and their correlation with tumor immune profile in recurrent cervical cancer. Tumor and adjacent normal tissues were used to identify potential combination therapy targets. We found that DNA damage repair pathway genes were significantly overexpressed in the tumor. Based on our results and other recent investigations, we suggest that combination immune checkpoint and PARP inhibitor therapy is a high priority consideration for patients with recurrent, previously treated cervical cancer. We also show that multiple epithelial-mesenchymal transition-related genes, including MAP2K4, ID2, JAK1, FGF2, PIK3R1, AKT3, FGF13, and STAT3 may be potential targets. Interestingly, high-throughput analysis of Cancer Genome Atlas data identified distinct targets, including Fatty acid synthase FASN and Matrix Metallopeptidase 1 MMP1 as novel, promising combination therapy partners. PMID- 30283448 TI - The Pathogenesis of Tuberculosis: The Early Infiltrate of Post-primary (Adult Pulmonary) Tuberculosis: A Distinct Disease Entity. AB - It has long been recognized that tuberculosis (TB) induces both protective and tissue damaging immune responses. This paper reviews nearly two centuries of evidence that protection and tissue damage are mediated by separate disease entities in humans. Primary TB mediates protective immunity to disseminated infection while post-primary TB causes tissue damage that results in formation of cavities. Both are necessary for continued survival of Mycobacterium tuberculosis (MTB). Primary TB has been extensively studied in humans and animals. Post primary TB, in contrast, is seldom recognized or studied. It begins as an asymptomatic early infiltrate that may resolve or progress by bronchogenic spread to caseous pneumonia that either fragments to produce cavities or is retained to produce post-primary granulomas and fibrocaseous disease. Primary and post primary TB differ in typical age of onset, histopathology, organ distribution, x ray appearance, genetic predisposition, immune status of the host, clinical course and susceptibility to protection by BCG. MTB is a highly successful human parasite because it produces both primary and post-primary TB as distinct disease entities in humans. No animal reproduces this sequence of lesions. Recognition of these facts immediately suggests plausible solutions, animal models and testable hypotheses to otherwise inaccessible questions of the immunity and pathogenesis of TB.

AB - CARD11 functions as a key signaling scaffold that controls antigen-induced lymphocyte activation during the adaptive immune response. Somatic mutations in CARD11 are frequently found in Non-Hodgkin lymphoma, and at least three classes of germline CARD11 mutations have been described as the basis for primary immunodeficiency. In this review, we summarize our current understanding of how CARD11 signals, how its activity is regulated, and how mutations bypass normal regulation to cause disease.

PMID- 30283449 TI - Glibenclamide Reduces Primary Human Monocyte Functions Against Tuberculosis Infection by Enhancing M2 Polarization. AB - Tuberculosis (TB) is a global public health problem, which is caused by Mycobacterium tuberculosis (Mtb). Type 2 diabetes mellitus (T2DM) is one of the leading predisposing factors for development of TB after HIV/AIDS. Glibenclamide is a widely used anti-diabetic drug in low and middle-income countries where the incidence of TB is very high. In a human macrophage cell line, glibenclamide, a K+ATP-channel blocker, promoted alternative activation of macrophages by enhancing expression of the M2 marker CD206 during M2 polarization. M2 macrophages are considered poorly microbicidal and associated with TB susceptibility. Here, we investigated the effect of glibenclamide on M1 and M2 phenotypes of primary human monocytes and further determined whether specific drug treatment for T2DM individuals influences the antibacterial function of monocytes in response to mycobacterial infection. We found that glibenclamide significantly reduced M1 (HLA-DR+ and CD86+) surface markers and TNF-alpha production on primary human monocytes against mycobacterial infection. In contrast, M2 (CD163+ and CD206+) surface markers and IL-10 production were enhanced by pretreatment with glibenclamide. Additionally, reduction of bactericidal activity also occurred when primary human monocytes from T2DM individuals who were being treated with glibenclamide were infected with Mtb in vitro, consistent with the cytokine responses. We conclude that glibenclamide reduces M1 and promotes M2 polarization leading to impaired bactericidal ability of primary human monocytes of T2DM individuals in response to Mtb and may lead to increased susceptibility of T2DM individuals to TB and other bacterial infectious diseases. PMID- 30283451 TI - Galleria mellonella: A Novel Invertebrate Model to Distinguish Intestinal Symbionts From Pathobionts. AB - Insects and mammals share evolutionary conserved innate immune responses to maintain intestinal homeostasis. We investigated whether the larvae of the greater wax moth Galleria mellonella may be used as an experimental organism to distinguish between symbiotic Bacteroides vulgatus and pathobiotic Escherichia coli, which are mammalian intestinal commensals. Oral application of the symbiont or pathobiont to G. mellonella resulted in clearly distinguishable innate immune responses that could be verified by analyzing similar innate immune components in mice in vivo and in vitro. The differential innate immune responses were initiated by the recognition of bacterial components via pattern recognition receptors. The pathobiont detection resulted in increased expression of reactive oxygen and nitrogen species related genes as well as antimicrobial peptide gene expression. In contrast, the treatment/application with symbiotic bacteria led to weakened immune responses in both mammalian and insect models. As symbionts and pathobionts play a crucial role in development of inflammatory bowel diseases, we hence suggest G. mellonella as a future replacement organism in inflammatory bowel disease research. PMID- 30283453 TI - Comprehensively Profiling the Chromatin Architecture of Tissue Restricted Antigen Expression in Thymic Epithelial Cells Over Development. AB - Thymic epithelial cells (TEC) effect crucial roles in thymopoiesis including the control of negative thymocyte selection. This process depends on their capacity to express promiscuously genes encoding tissue-restricted antigens. This competence is accomplished in medullary TEC (mTEC) in part by the presence of the transcriptional facilitator AutoImmune REgulator, AIRE. AIRE-regulated gene transcription is marked by repressive chromatin modifications, including H3K27me3. When during TEC development these chromatin marks are established, however, remains unclear. Here we use a comprehensive ChIP-seq dataset of multiple chromatin modifications in different TEC subtypes to demonstrate that the chromatin landscape is established early in TEC differentiation. Much of the chromatin architecture found in mature mTEC was found to be present already over earlier stages of mTEC lineage differentiation as well as in non-TEC tissues. This was reflected by the fact that a machine learning approach accurately classified genes as AIRE-induced or AIRE-independent both in immature and mature mTEC. Moreover, analysis of TEC specific enhancer elements identified candidate transcription factors likely to be important in mTEC development and function. Our findings indicate that the mature mTEC chromatin landscape is laid down early in mTEC differentiation, and that AIRE is not required for large-scale re patterning of chromatin in mTEC. PMID- 30283452 TI - Redox-Mediated Mechanisms Fuel Monocyte Responses to CXCL12/HMGB1 in Active Rheumatoid Arthritis. AB - Chemokine synergy-inducing molecules are emerging as regulating factors in cell migration. The alarmin HMGB1, in its reduced form, can complex with CXCL12 enhancing its activity on monocytes via the chemokine receptor CXCR4, while the form containing a disulfide bond, by binding to TLR2 or TLR4, initiates a cascade of events leading to production of cytokines and chemokines. So far, the possibility that the CXCL12/HMGB1 heterocomplex could be maintained in chronic inflammation was debated, due to the release of reactive oxygen species. Therefore, we have assessed if the heterocomplex could remain active in Rheumatoid Arthritis (RA) and its relevance in the disease assessment. Monocytes from RA patients with active disease require a low concentration of HMGB1 to enhance CXCL12-induced migration, in comparison to monocytes from patients in clinical remission or healthy donors. The activity of the heterocomplex depends on disease activity, on the COX2 and JAK/STAT pathways, and is determined by the redox potential of the microenvironment. In RA, the presence of an active thioredoxin system correlates with the enhanced cell migration, and with the presence of the heterocomplex in the synovial fluid. The present study highlights how, in an unbalanced microenvironment, the activity of the thioredoxin system plays a crucial role in sustaining inflammation. Prostaglandin E2 stimulation of monocytes from healthy donors is sufficient to recapitulate the response observed in patients with active RA. The activation of mechanisms counteracting the oxidative stress in the extracellular compartment preserves HMGB1 in its reduced form, and contributes to fuel the influx of inflammatory cells. Targeting the heterocomplex formation and its activity could thus be an additional tool for dampening the inflammation sustained by cell recruitment, for those patients with chronic inflammatory conditions who poorly respond to current therapies. PMID- 30283454 TI - Tc17/IL-17A Up-Regulated the Expression of MMP-9 via NF-kappaB Pathway in Nasal Epithelial Cells of Patients With Chronic Rhinosinusitis. AB - Chronic rhinosinusitis (CRS) is a common chronic inflammatory disease of the upper airways involving nasal cavity and sinus. Deriving both from its clinical complexity with protean clinical manifestations as well its pathogenetic heterogeneity, the molecular mechanisms contributing to the pathogenesis of CRS remain unclear, and attract a wide interest in the field. Current evidences indicate that IL-17A is highly expressed in chronic rhinosinusitis with nasal polyps (CRSwNP). However, its pathogenetic role in regulation of tissue remodeling of CRSwNP remains unknown. The present study aimed to investigate the cellular origins and functions of IL-17A cytokine in CRSwNP, and further determined whether IL-17A could affect the expression of metalloproteinases (MMPs), the remodeling factors of CRSwNP. The results showed that the expression of IL-17A was upregulated in nasal tissues of patients with CRSwNP compared to those with chronic rhinosinusitis without nasal polyps (CRSsNP) and controls. CD8+ cytotoxic T lymphocytes (Tc) were major IL-17A producers in nasal tissues of CRSwNP. Interleukin (IL)-17-producing CD8+ T cells (Tc17) was significantly higher in nasal tissues of CRSwNP than CRSsNP and controls. Nonetheless, no difference was observed among the IL-17A in peripheral blood lymphocytes of these three groups. Moreover, in the same patients, IL-17A expression was negligible in lymphocytes of peripheral blood when compared with nasal tissues. Increased gene and protein expression of MMP-7 and MMP-9 in patients with CRSwNP compared with controls were observed. In CRSwNP samples, IL-17A receptor (IL-17AR) co-localized with MMP-9 and they were mainly expressed in the epithelial cells. MMP-9 expression was up-regulated both in Primary human nasal epithelial cells (PHNECs) and a nasal epithelial cell line (RPMI 2650) by IL-17A treatment, and diminished by anti-IL-17AR treatment. Furthermore, IL-17A promoted the expression of MMP-9 by activating the NF-kappaB signal pathway. Thus, our results have revealed a crucial role of IL-17A and Tc cells on pathogenesis and tissue remodeling of CRSwNP. PMID- 30283455 TI - Cerebrospinal Fluid Inflammatory Cytokine Aberrations in Alzheimer's Disease, Parkinson's Disease and Amyotrophic Lateral Sclerosis: A Systematic Review and Meta-Analysis. AB - It has been suggested that cytokine-mediated inflammation plays a key role for the onset and/or development of neurodegenerative diseases including Alzheimer's disease (AD), Parkinson's disease (PD) and Amyotrophic lateral sclerosis (ALS). However, clinical studies have yielded inconsistent results for the aberrant cytokine levels in circulation of patients with AD, PD, and ALS. Previous studies have used meta-analysis to address the inconsistent data for blood cytokine levels in the patients with AD, PD, and ALS. Here, we performed a systemic review of cerebrospinal fluid inflammatory cytokine data in patients with AD, PD and ALS, and sought to quantitatively summarize the CSF inflammatory cytokine data with a meta-analytical technique. The systematic search from Pubmed and Web of Science identified 71 articles with 2629 patients and 2049 controls for the meta analysis. Random-effects meta-analysis demonstrated that CSF TGF-beta, MCP-1, and YKL-40 levels were significantly elevated in AD patients when compared with controls. In addition, patients with PD had heightened levels of TGF-beta1, IL-6, and IL-1beta in CSF. Furthermore, G-CSF, IL-2, IL-15, IL-17, MCP-1, MIP-1alpha, TNF-alpha, and VEGF levels were significantly increased in patients with ALS as compared with controls. Taken together, these results not only strengthen the clinical evidence that neurodegenerative diseases are accompanied by the increased inflammatory response, but also reveal the unique inflammatory response profile in the central nervous system of patients with AD, PD and ALS. Given the robust associations between some cytokines and neurodegenerative diseases found in this meta-analysis, CSF inflammatory cytokines may be used as biomarkers for these diseases in the future.

AB - Despite advances in diagnosing latent Mycobacterium tuberculosis infection (LTBI), we still lack a diagnostic test that differentiates LTBI from active tuberculosis (TB) or predicts the risk of progression to active disease. One reason for the absence of such a test may be the failure of current assays to capture the dynamic complexities of the immune responses associated with various stages of TB, since these assays measure only a single parameter (release of IFN gamma) and rely on prolonged (overnight) T cell stimulation. We describe a novel, semi-automated RNA flow cytometry assay to determine whether immunological differences can be identified between LTBI and active TB. We analyzed antigen induced expression of Th1 cytokine mRNA after short (2- and 6-h) stimulation with antigen, in the context of memory T cell immunophenotyping. IFNG and TNFA mRNA induction was detectable in CD4+ T cells after only 2 h of ex vivo stimulation. Moreover, IFNG- and TNFA-expressing CD4+ T cells (Th1 cells) were more frequent in active TB than in LTBI, a difference that is undetectable with conventional, protein-based cytokine assays. We also found that active TB was associated with higher ratios of effector memory to central memory Th1 cells than LTBI. This effector memory phenotype of active TB was associated with increased T cell differentiation, as defined by loss of the CD27 marker, but not with T cell exhaustion, as determined by PD-1 abundance. These results indicate that single cell-based, mRNA measurements may help identify time-dependent, quantitative differences in T cell functional status between latent infection and active tuberculosis. PMID- 30283457 TI - Intrinsic Programming of Alveolar Macrophages for Protective Antifungal Innate Immunity Against Pneumocystis Infection. AB - Invasive fungal infections, including Pneumocystis Pneumonia (PcP), remain frequent life-threatening conditions of patients with adaptive immune defects. While innate immunity helps control pathogen growth early during infection, it is typically not sufficient for complete protection against Pneumocystis and other human fungal pathogens. Alveolar macrophages (AM) possess pattern recognition molecules capable of recognizing antigenic and structural determinants of Pneumocystis. However, this pathogen effectively evades innate immunity to infect both immunocompetent and immunosuppressed hosts, albeit with differing outcomes. During our studies of mouse models of PcP, the FVB/N strain was identified as unique because of its ability to mount a protective innate immune response against Pneumocystis infection. In contrast to other immunocompetent strains, which become transiently infected prior to the onset of adaptive immunity, FVB/N mice rapidly eradicated Pneumocystis before an adaptive immune response was triggered. Furthermore, FVB/N mice remained highly resistant to infection even in the absence of functional T cells. The effector mechanism of innate protection required the action of functional alveolar macrophages, and the adoptive transfer of resistant FVB/N AMs, but not susceptible CB.17 AMs, conferred protection to immunodeficient mice. Macrophage IFNgamma receptor signaling was not required for innate resistance, and FVB/N macrophages were found to display markers of alternative activation. IFNgamma reprogrammed resistant FVB/N macrophages to a permissive M1 biased phenotype through a mechanism that required direct activation of the macrophage IFNgammaR. These results demonstrate that appropriately programmed macrophages provide protective innate immunity against this opportunistic fungal pathogen, and suggest that modulating macrophage function may represent a feasible therapeutic strategy to enhance antifungal host defense. The identification of resistant and susceptible macrophages provides a novel platform to study not only the mechanisms of macrophage-mediated antifungal defense, but also the mechanisms by which Pneumocystis evades innate immunity. PMID- 30283460 TI - Autoantibodies Against Perilipin 1 as a Cause of Acquired Generalized Lipodystrophy. AB - Acquired generalized lipodystrophy (AGL) is a rare condition characterized by an altered distribution of adipose tissue and predisposition to develop hepatic steatosis and fibrosis, diabetes, and hypertriglyceridemia. Diagnosis of AGL is based on the observation of generalized fat loss, autoimmunity and lack of family history of lipodystrophy. The pathogenic mechanism of fat destruction remains unknown but evidences suggest an autoimmune origin. Anti-adipocyte antibodies have been previously reported in patients with AGL, although their involvement in the pathogenesis has been poorly studied and the autoantibody target/s remain/s to be identified. Using a combination of immunochemical and cellular studies, we investigated the presence of anti-adipocyte autoantibodies in patients with AGL, acquired partial lipodystrophy, localized lipoatrophy due to intradermic insulin injections or systemic lupus erythematosus. Moreover, the impact of anti adipocyte autoantibodies from AGL patients was assessed in cultured mouse preadipocytes. Following this approach, we identified anti-perilipin 1 IgG autoantibodies in the serum of patients with autoimmune variety-AGL, but in no other lipodystrophies tested. These autoantibodies altered the ability of perilipin 1 to regulate lipolysis in cultured preadipocytes causing abnormal, significantly elevated basal lipolysis. Our data provide strong support for the conclusion that perilipin 1 autoantibodies are a cause of generalized lipodystrophy in these patients. PMID- 30283458 TI - Nematode-Infected Mice Acquire Resistance to Subsequent Infection With Unrelated Nematode by Inducing Highly Responsive Group 2 Innate Lymphoid Cells in the Lung. AB - The immune responses against helminths have been investigated individually, and it is well-established that infected hosts develop an immunological memory to resist reinfection by the same pathogen. In contrast, it is poorly understood how the host immune system responds to subsequent infection by unrelated parasites after elimination of the first infection. We previously reported that infection of mice with Strongyloides venezuelensis induces the accumulation of group 2 innate lymphoid cells (ILC2s) in the lung. Here, we demonstrated that S. venezuelensis-experienced (Sv-exp) mice became significantly resistant against infection by Nippostrongylus brasiliensis. N. brasiliensis infection induced enhanced accumulation of ILC2s and eosinophils with increased expressions of mRNA for Th2 cytokines in the lungs of Sv-exp mice. The resistance was dependent on ILC2s, and eosinophils but not on CD4+ T cells. Furthermore, pulmonary ILC2s in Sv-exp mice acquired a highly responsive "trained" phenotype; in response to N. brasiliensis infection, they rapidly increased and produced IL-5 and IL-13, which in turn induced the early accumulation of eosinophils in the lungs. IL-33 was required for the accumulation of ILC2s and the resistance of mice against N. brasiliensis infection but insufficient for the induction of trained ILC2s. In conclusion, animals infected with one type of lung-migratory nematodes acquire a specific-antigen-independent resistance to another type of lung-migrating nematodes, providing animals with the capacity to protect against sequential infections with various lung-migratory nematodes. PMID- 30283459 TI - Genome-Wide Inhibition of Pro-atherogenic Gene Expression by Multi-STAT Targeting Compounds as a Novel Treatment Strategy of CVDs. AB - Cardiovascular diseases (CVDs), including atherosclerosis, are globally the leading cause of death. Key factors contributing to onset and progression of atherosclerosis include the pro-inflammatory cytokines Interferon (IFN)alpha and IFNgamma and the Pattern Recognition Receptor (PRR) Toll-like receptor 4 (TLR4). Together, they trigger activation of Signal Transducer and Activator of Transcription (STAT)s. Searches for compounds targeting the pTyr-SH2 interaction area of STAT3, yielded many small molecules, including STATTIC and STX-0119. However, many of these inhibitors do not seem STAT3-specific. We hypothesized that multi-STAT-inhibitors that simultaneously block STAT1, STAT2, and STAT3 activity and pro-inflammatory target gene expression may be a promising strategy to treat CVDs. Using comparative in silico docking of multiple STAT-SH2 models on multi-million compound libraries, we identified the novel multi-STAT inhibitor, C01L_F03. This compound targets the SH2 domain of STAT1, STAT2, and STAT3 with the same affinity and simultaneously blocks their activity and expression of multiple STAT-target genes in HMECs in response to IFNalpha. The same in silico and in vitro multi-STAT inhibiting capacity was shown for STATTIC and STX-0119. Moreover, C01L_F03, STATTIC and STX-0119 were also able to affect genome-wide interactions between IFNgamma and TLR4 by commonly inhibiting pro-inflammatory and pro-atherogenic gene expression directed by cooperative involvement of STATs with IRFs and/or NF-kappaB. Moreover, we observed that multi-STAT inhibitors could be used to inhibit IFNgamma+LPS-induced HMECs migration, leukocyte adhesion to ECs as well as impairment of mesenteric artery contractility. Together, this implicates that application of a multi-STAT inhibitory strategy could provide great promise for the treatment of CVDs. PMID- 30283461 TI - Durable Clinical Responses and Long-Term Follow-Up of Stage III-IV Non-Small-Cell Lung Cancer (NSCLC) Patients Treated With IDO Peptide Vaccine in a Phase I Study A Brief Research Report. AB - Background: Long-term follow-up on a clinical trial of 15 stage III-IV NSCLC patients treated with an Indoleamine 2,3-Dioxygenase (IDO) peptide vaccine (NCT01219348). Methods: Fifteen HLA-A2-positive patients with stable stage III-IV NSCLC after standard chemotherapy were treated with subcutaneous vaccinations (100 MUg IDO5 peptide, sequence ALLEIASCL, formulated in 900 MUl Montanide) biweekly for 2.5 months and thereafter monthly until progression or up to 5 years. Here we report long-term clinical follow-up, toxicity and immunity. Results: Three of 15 patients are still alive corresponding to a 6-year overall survival of 20 %. Two patients continued monthly vaccinations for 5 years (56 vaccines). One of the two patients developed a partial response (PR) of target lesions in the liver 15 months after the first vaccine and has remained in PR ever since. The other patient had a solitary distant metastasis in a lymph node in retroperitoneum at baseline which normalized during treatment. All following evaluation scans during the treatment have been tumor free. The vaccine was well tolerated for all 5 years with no long-term toxicities registered. The third long term surviving patient discontinued vaccinations after 11 months due to disease progression. Flow cytometry analyses of PBMCs from the two long-term responders demonstrated stable CD8+ and CD4+ T-cell populations during treatment. In addition, presence of IDO-specific T-cells was detected by IFN-gamma Elispot in both patients at several time points during treatment. Conclusion: IDO peptide vaccination was well tolerated for administration up to 5years. Two of 15 patients are long-term responders with ongoing clinical response 6 years after 1st vaccination. PMID- 30283463 TI - Identification of Major QTLs Associated With First Pod Height and Candidate Gene Mining in Soybean. AB - First pod height (FPH) is a quantitative trait in soybean [Glycine max (L.) Merr.] that affects mechanized harvesting. A compatible combination of the FPH and the mechanized harvester is required to ensure that the soybean is efficiently harvested. In this study, 147 recombinant inbred lines, which were derived from a cross between 'Dongnong594' and 'Charleston' over 8 years, were used to identify the major quantitative trait loci (QTLs) associated with FPH. Using a composite interval mapping method with WinQTLCart (version 2.5), 11 major QTLs were identified. They were distributed on five soybean chromosomes, and 90 pairs of QTLs showed significant epistatic associates with FPH. Of these, 3 were main QTL * main QTL interactions, and 12 were main QTL * non-main QTL interactions. A KEGG gene annotation of the 11 major QTL intervals revealed 8 candidate genes related to plant growth, appearing in the pathways K14486 (auxin response factor 9), K14498 (serine/threonine-protein kinase), and K13946 (transmembrane amino acid transporter family protein), and 7 candidate genes had high expression levels in the soybean stems. These results will aid in building a foundation for the fine mapping of the QTLs related to FPH and marker-assisted selection for breeding in soybean. PMID- 30283462 TI - GWAS Analysis and QTL Identification of Fiber Quality Traits and Yield Components in Upland Cotton Using Enriched High-Density SNP Markers. AB - It is of great importance to identify quantitative trait loci (QTL) controlling fiber quality traits and yield components for future marker-assisted selection (MAS) and candidate gene function identifications. In this study, two kinds of traits in 231 F6:8 recombinant inbred lines (RILs), derived from an intraspecific cross between Xinluzao24, a cultivar with elite fiber quality, and Lumianyan28, a cultivar with wide adaptability and high yield potential, were measured in nine environments. This RIL population was genotyped by 122 SSR and 4729 SNP markers, which were also used to construct the genetic map. The map covered 2477.99 cM of hirsutum genome, with an average marker interval of 0.51 cM between adjacent markers. As a result, a total of 134 QTLs for fiber quality traits and 122 QTLs for yield components were detected, with 2.18-24.45 and 1.68-28.27% proportions of the phenotypic variance explained by each QTL, respectively. Among these QTLs, 57 were detected in at least two environments, named stable QTLs. A total of 209 and 139 quantitative trait nucleotides (QTNs) were associated with fiber quality traits and yield components by four multilocus genome-wide association studies methods, respectively. Among these QTNs, 74 were detected by at least two algorithms or in two environments. The candidate genes harbored by 57 stable QTLs were compared with the ones associated with QTN, and 35 common candidate genes were found. Among these common candidate genes, four were possibly "pleiotropic." This study provided important information for MAS and candidate gene functional studies. PMID- 30283465 TI - Comprehensive Analysis of MYB Gene Family and Their Expressions Under Abiotic Stresses and Hormone Treatments in Tamarix hispida. AB - The MYB transcription factors (TFs) is a plant TF families, which involves in hormone signal transduction, and abiotic stress tolerance, etc. However, there are few studies on the MYB TFs family and its regulatory mechanism in Tamarix hispida. In this study, 14 MYB genes (named ThMYB1 - ThMYB14) were cloned and characterized from T. hispida. The transcription profiles of ThMYBs in T. hispida under different abiotic stress conditions were monitored using qRT-PCR. Most of studied ThMYBs were significantly downregulated and/or upregulated by salt and osmotic stress, ABA, GA3 and JA treatments in at least one organ. Especially, ThMYB13 was induced in the leaves and roots of T. hispida when exposed to NaCl treatment at all study periods, indicating that it may involve in salt stress. To further study ThMYB13 function, ThMYB13 overexpression and knock-down plants and control plants transformed with an empty pROKII were obtained using a transient transformation system. Overexpression of ThMYB13 in T. hispida displayed the lowest O2-, H2O2 and MDA accumulation, minimal cell death, the most stable K+/Na+ ratio and the lowest electrolyte leakage rate among the three kinds of transient expression in T. hispida. Conversely, the RNAi-silencing, transiently transformed plants displayed the opposite physiological changes. Therefore, ThMYB13 might play a role in salt stress tolerance in transgenic T. hispida plants. PMID- 30283464 TI - Systematic Analysis of Cotton Non-specific Lipid Transfer Protein Family Revealed a Special Group That Is Involved in Fiber Elongation. AB - Non-specific lipid transfer proteins (nsLTPs) had been previously isolated from cotton fiber but their functions were unclear so far. Bioinformatic analysis of the tetraploid cotton genome database identified 138 nsLTP genes, falling into the 11 groups as reported previously. Different from Arabidopsis, cacao, and other crops, cotton type XI genes were considerably expanded and diverged earlier on chromosome At11, Dt11, and Dt08. Corresponding to the type XI genes, the type XI proteins (GhLtpXIs) all contained an extra N-terminal cap resulting in larger molecular weight. The research revealed that the expression of type XI genes was dramatically increased in fibers of tetraploid cotton compared with the two diploid progenitors. High-level of GhLtpXIs expression was observed in long fibered cotton cultivars during fiber elongation. Ectopic expression of GhLtpXIs in Arabidopsis significantly enhanced trichome length, suggesting that GhLtpXIs promoted fiber elongation. Overall, the findings of this research provide insights into phenotypic evolution of Gossypium species and regulatory mechanism of nsLTPs during fiber development. HIGHLIGHT A specific group, type XI nsLTPs, was identified with predominant expression in elongating fibers of Gossypium hirsutum based on evolutionary, transcriptional, and functional analyses. PMID- 30283467 TI - New Plant Breeding Techniques Under Food Security Pressure and Lobbying. AB - Different countries have different regulations for the approval and cultivation of crops developed by using new plant breeding technologies (NPBTs) such as gene editing. In this paper, we investigate the relationship between global food security and the level of NPBT regulation assuming a World Nation Official (WNO) proposes advice on global NPBT food policies. We show that a stricter NPBT food regulation reduces food security as measured by food availability, access, and utilization. We also find that political rivalry among interest groups worsens the food security status, given the NPBT food technology is more productive and the regulatory policy is influenced by lobbying. When the WNO aims to improve food security and weighs the NPBT food lobby contribution more than the non-NPBT food lobby's in the lobbying game, the total lobbying contributions will be the same for the WNO, and the NPBT food lobby will be more successful in the political process. The NPBT food lobby, however, under food security loses its advantage in the political competition, and this may result in a strict NPBT food policy. Under food security problems implementing stricter NPBT food regulations results in welfare losses. JEL Code: D04, D43, D72, P16. PMID- 30283466 TI - Harnessing the Potential of Forage Legumes, Alfalfa, Soybean, and Cowpea for Sustainable Agriculture and Global Food Security. AB - Substantial improvements in access to food and increased purchasing power are driving many people toward consuming nutrition-rich foods causing an unprecedented demand for protein food worldwide, which is expected to rise further. Forage legumes form an important source of feed for livestock and have potential to provide a sustainable solution for food and protein security. Currently, alfalfa is a commercially grown source of forage and feed in many countries. However, soybean and cowpea also have the potential to provide quality forage and fodder for animal use. The cultivation of forage legumes is under threat from changing climatic conditions, indicating the need for breeding cultivars that can sustain and acclimatize to the negative effects of climate change. Recent progress in genetic and genomic tools have facilitated the identification of quantitative trait loci and genes/alleles that can aid in developing forage cultivars through genomics-assisted breeding. Furthermore, transgenic technology can be utilized to manipulate the genetic makeup of plants to improve forage digestibility for better animal performance. In this article, we assess the genetic potential of three important legume crops, alfalfa, soybean, and cowpea in supplying quality fodder and feed for livestock. In addition, we examine the impact of climate change on forage quality and discuss efforts made in enhancing the adaptation of the plant to the abiotic stress conditions. Subsequently, we suggest the application of integrative approaches to achieve adequate forage production amid the unpredictable climatic conditions. PMID- 30283468 TI - Genome-Wide Identification, Characterization, and Expression Profiling of the Legume BZR Transcription Factor Gene Family. AB - The BRASSINAZOLE-RESISTANT (BZR) family of transcription factors (TFs) are positive regulators in the biosynthesis of brassinosteroids. The latter is a class of steroid hormones that affect a variety of developmental and physiological processes in plants. BZR TFs play essential roles in the regulation of plant growth and development, including multiple stress-resistance functions. However, the evolutionary history and individual expression patterns of the legume BZR genes has not been determined. In this study, we performed a genome wide investigation of the BZR gene family in seven legume species. In total, 52 BZR genes were identified and characterized. By analyzing their phylogeny, we divided these BZR genes into five groups by comparison with orthologs/paralogs in Arabidopsis thaliana. The intron/exon structural patterns and conserved protein motifs of each gene were analyzed and showed high group-specificities. Legume BZR genes were unevenly distributed among their corresponding genomes. Genome and gene sequence comparisons revealed that gene expansion of the BZR TF family in legumes mainly resulted from segmental duplications and that this family has undergone purifying selection. Synteny analysis showed that BZR genes tended to localize within syntenic blocks conserved across legume genomes. The expression patterns of BZR genes among various legume vegetative tissues and in response to different abiotic stresses were analyzed using a combination of public transcriptome data and quantitative PCR. The patterns indicated that many BZR genes regulate legume organ development and differentiation, and significantly respond to drought and salt stresses. This study may provide valuable information for understanding the evolution of BZR gene structure and expression, and lays a foundation for future functional analysis of the legume BZR genes by species and by gene. PMID- 30283469 TI - Heat in Wheat: Exploit Reverse Genetic Techniques to Discover New Alleles Within the Triticum durum sHsp26 Family. AB - Wheat breeding nowadays must address producers and consumers' desire. According to the last FAO report, a dramatic decrease in wheat production is expected in the next decades mainly due to the upcoming climate change. The identification of the processes which are triggered by heat stress and how thermotolerance develops in wheat is an active research topic. Genomic approach may help wheat breeding since it allows direct study on the genotype and relationship with the phenotype. Here the isolation and characterization of four members of the chloroplast localized small heat shock proteins (sHSP) encoded by the Hsp26 gene family is reported. Furthermore, two high throughput TILLING (Targeting Induced Local Lesions In Genomes) approaches in vivo and in silico were used for the identification of new alleles within this family. Small heat shock proteins are known to prevent the irreversible aggregation of misfolded proteins and contribute to the acquisition of thermotolerance. Chloroplast-localized sHSPs protect the photosynthetic machinery during episodes of high temperature stress. The modulation of the newly discovered genes within the sHsp26 family has been analyzed in vivo and by the ExpVIP platform widening the abiotic stress analysis; and their involvement in the heat stress response has been demonstrated. In addition, in this study a total of 50 TILLING mutant lines have been identified. A set of KASP (Kompetitive Allele Specific PCR) markers was also developed to follow the specific mutations in the ongoing backcrosses, applicable to high throughput genotyping approaches and usable in marker assisted selection breeding programs. PMID- 30283470 TI - Bioinformatic and in vitro Analyses of Arabidopsis Starch Synthase 2 Reveal Post translational Regulatory Mechanisms. AB - Starch synthase 2 (SS2) is an important enzyme in leaf starch synthesis, elongating intermediate-length glucan chains. Loss of SS2 results in a distorted starch granule phenotype and altered physiochemical properties, highlighting its importance in starch biosynthesis, however, the post-translational regulation of SS2 is poorly understood. In this study, a combination of bioinformatic and in vitro analysis of recombinant SS2 was used to identify and characterize SS2 post translational regulatory mechanisms. The SS2 N-terminal region, comprising the first 185 amino acids of the mature protein sequence, was shown to be highly variable between species, and was predicted to be intrinsically disordered. Intrinsic disorder in proteins is often correlated with protein phosphorylation and protein-protein interactions. Recombinant Arabidopsis thaliana SS2 formed homodimers that required the N-terminal region, but N-terminal peptides could not form stable homodimers alone. Recombinant SS2 was shown to be phosphorylated by chloroplast protein kinases and recombinant casein kinase II at two N-terminal serine residues (S63, S65), but mutation of these phosphorylation sites (Ser>Ala) revealed that they are not required for homo-dimerization. Heteromeric enzyme complex (HEC) formation between SS2 and SBE2.2 was shown to be ATP-dependent. However, SS2 homo-dimerization and protein phosphorylation are not required for its interaction with SBE2.2, as truncation of the SS2 N-terminus did not disrupt ATP-dependent HEC assembly. SS2 phosphorylation had no affect on its catalytic activity. Intriguingly, the removal of the N-terminal region of SS2 resulted in a 47-fold increase in its activity. As N-terminal truncation disrupted dimerization, this suggests that SS2 is more active when monomeric, and that transitions between oligomeric state may be a mechanism for SS2 regulation. PMID- 30283471 TI - The HEM Lines: A New Library of Homozygous Arabidopsis thaliana EMS Mutants and its Potential to Detect Meiotic Phenotypes. AB - Genetic screens have been crucial for deciphering many important biological processes, including meiosis. In Arabidopsis thaliana, previous forward screens have likely identified almost all the meiotic genes that when mutated lead to a pronounced decrease in fertility. However, the increasing number of genes identified in reverse genetics studies that play crucial roles in meiosis, but do not exhibit strong phenotypes when mutated, suggests that there are still many genes with meiotic function waiting to be discovered. In this study, we produced 897 A. thaliana homozygous mutant lines using Ethyl Methyl Sulfonate (EMS) mutagenesis followed by either single seed descent or haploid doubling. Whole genome sequencing of a subset of lines showed an average of 696 homozygous mutations per line, 195 of which (28%) modify a protein sequence. To test the power of this library, we carried out a forward screen looking for meiotic defects by observing chromosomes at metaphase I of male meiosis. Among the 649 lines analyzed, we identified 43 lines with meiotic defects. Of these, 21 lines had an obvious candidate causal mutation, namely a STOP or splicing site mutation in a gene previously shown to play a role in meiosis (ATM, MLH3, MLH1, MER3, HEI10, FLIP, ASY4, FLIP, PRD2, REC8, FANCL, and PSS1). Interestingly, this was the first time that six of these genes were identified in a forward screen in Arabidopsis (MLH3, MLH1, SGO1, PSS1, FANCL, and ASY4). These results illustrate the potential of this mutant population for screening for any qualitative or quantitative phenotype. Thus, this new mutant library is a powerful tool for functional genomics in A. thaliana. The HEM (Homozygote EMS Mutants) lines are available at the Versailles Arabidopsis stock center. PMID- 30283472 TI - Light-Dependent Changes in the Spatial Localization of Metabolites in Solenostemon scutellarioides (Coleus Henna) Visualized by Matrix-Free Atmospheric Pressure Electrospray Laser Desorption Ionization Mass Spectrometry Imaging. AB - The visualization of foliage color in plants provides immediate insight into some of the compounds that exist in the leaf. However, many non-colored compounds are also present; their cellular distributions are not readily identifiable optically. In this study we evaluate the applicability of mass spectrometry imaging (MSI) via electrospray laser desorption ionization (ELDI) to reveal the spatial distribution of metabolites. ELDI-MSI is a matrix free, atmospheric pressure ionization method that utilizes a UV laser coupled with supplemental ionization by electrospray. We specifically applied ELDI-MSI to determine the spatial distribution of metabolites in Coleus Henna half leaves that were grown with half-sections either fully illuminated or shaded. We monitored dynamic changes in the spatial distribution of metabolites in response to the change of illumination every 7 days for a 28 day period. A novel source-sink relationship was observed between the 2 halves of the experimental leaf. Furthermore, Coleus Henna leaves present visually recognizable sectors associated with the differential accumulation of flavonoids. Thus, we correlated the effect of differential illumination and presence or absence of flavonoids with metabolic changes revealed by the accumulation of carbohydrates, amino acids, and organic acids. The results show the potential of ELDI-MSI to provide spatial information for a variety of plant metabolites with little sample preparation. PMID- 30283474 TI - Relative Contribution of Nitrogen Absorption, Remobilization, and Partitioning to the Ear During Grain Filling in Chinese Winter Wheat. AB - Knowledge of the function of the ear as a key organ in the uptake, remobilization and partitioning of nitrogen is essential for understanding its contribution to grain filling and thus guiding future breeding strategies. In this work, four Chinese winter wheat genotypes were grown on a 15N-enriched nutrient solution. N absorption and further remobilization to the flag leaf, the ear and the mature grains were calculated via the 15N atom % excess. The results indicated that the high yields of the Chinese wheat genotype were determined by higher grain numbers per ear, with greater plant height and a larger ear size, while the thousand grain weight did not affect grain yield. In the mature grains, 66.7% of total N was remobilized from the pre-anthesis accumulation in the biomass, while the remaining 33.3% was derived from the N taken up during post-anthesis. From anthesis to 2 weeks after the anthesis stage, the flag leaf remobilized 3.67 mg of N outwards and the ear remobilized 3.87 mg of N inwards from the pre-anthesis accumulation in each plant. The positive correlation between ear Nrem and grain Nrem indicated that the ear was an important organ for providing N to the grain, whereas the remobilized N stream from the leaves was not correlated with grain Nrem, thus indicating that flag leaf N was not translocated directly to the grain. The grain Nrem was negatively correlated with the ear N concentration throughout grain filling, which suggested that higher-yielding genotypes had better sink activity in the ear, while Rubisco played a critical role in N deposition. Therefore, to improve yield potential in wheat, the N accumulation in the ear and the subsequent remobilization of that stored N to the grains should be considered. N accumulation and remobilization in the ear may at least be valuable for Chinese breeding programs that aim at optimizing the sink/source balance to improve grain filling. PMID- 30283473 TI - The Times They Are A-Changin': Heterochrony in Plant Development and Evolution. AB - Alterations in the timing of developmental programs during evolution, that lead to changes in the shape, or size of organs, are known as heterochrony. Heterochrony has been widely studied in animals, but has often been neglected in plants. During plant evolution, heterochronic shifts have played a key role in the origin and diversification of leaves, roots, flowers, and fruits. Heterochrony that results in a juvenile or simpler outcome is known as paedomorphosis, while an adult or more complex outcome is called peramorphosis. Mechanisms that alter developmental timing at the cellular level affect cell proliferation or differentiation, while those acting at the tissue or organismal level change endogenous aging pathways, morphogen signaling, and metabolism. We believe that wider consideration of heterochrony in the context of evolution will contribute to a better understanding of plant development. PMID- 30283475 TI - Evidence for the Extensive Conservation of Mechanisms of Ovule Integument Development Since the Most Recent Common Ancestor of Living Angiosperms. AB - The ovules and seeds of most angiosperm groups are enclosed by two integuments, whose evolutionary origins are considerably separated in time, as the inner integument arose over 300 million years ago (MYA) in an ancestor of all living seed plants, while the outer integument arose, perhaps as recently as 164 MYA, in an ancestor of all living angiosperms. Studies of the model angiosperm Arabidopsis thaliana indicate that the mechanisms of development of the inner and outer integuments depend on largely different sets of molecular players. However, it was not known, in most cases, whether these differences were already present in early flowering plants, or arose later in the Arabidopsis lineage. Here, we analyze the expression patterns of integument regulators in Amborella trichopoda, the likely sister to all other living angiosperms. The data obtained indicate that regulators of the YABBY, KANADI, and homeodomain-leucine zipper class III transcription factor families have largely conserved their integument-specific expression profiles in the Amborella and Arabidopsis lineages since the most recent common ancestor (MRCA) of living angiosperms. We identified only one case, involving the paralogous genes ETTIN and AUXIN RESPONSE FACTOR4, in which integument-specific expression patterns had clearly diverged between Amborella and Arabidopsis. We use the data obtained to partially reconstruct molecular mechanisms of integument development in the MRCA of living angiosperms and discuss our findings in the context of alternative hypotheses for the origin of the angiosperm outer integument. PMID- 30283476 TI - Multi-Environmental Trials Reveal Genetic Plasticity of Oat Agronomic Traits Associated With Climate Variable Changes. AB - Although oat cultivation around the Mediterranean basin is steadily increasing, its yield in these regions lags far behind those of Northern Europe. This results mainly from the poor adaptation of current oat cultivars to Mediterranean environments. Local landraces may act as reservoirs of favorable traits that could contribute to increase oat resilience in this region. To aid selection of suitable agro-climate adapted genotypes we integrated genome-wide association approaches with analysis of field assessed phenotypes of genetic variants and of the weight of associated markers across different environmental variables. Association models accounting for oat population structure were applied on either arithmetic means or best linear unbiased prediction (BLUPs) to ensure robust identification of associations with the agronomic traits evaluated. The meta analysis of the six joint environments (mega-environment) identified several markers associated with several agronomic traits and crown rust severity. Five of these associated markers were located within expressed genes. These associations were only mildly influenced by climatic variables indicating that these markers are good candidates to improve the genetic potential of oat under Mediterranean conditions. The models also highlighted several marker-trait associations, strongly affected by particular climatic variables including high rain pre- or post-heading dates and high temperatures, revealing strong potential for oat adaptation to specific agro-climatic conditions. These results will contribute to increase oat resilience for particular climatic conditions and facilitate breeding for plant adaptation to a wider range of climatic conditions in the current scenario of climate change.

AB - Stomata play a critical role in the regulation of gas exchange between the interior of the leaf and the exterior environment and are affected by environmental and endogenous stimuli. This study aimed to evaluate the effect of the arbuscular mycorrhizal (AM) fungus, Rhizophagus irregularis, on the stomatal behavior of wheat (Triticum aestivum L.) plants under combination with elevated CO2 and NaCl stress. Wheat seedlings were exposed to ambient (400 ppm) or elevated (700 ppm) CO2 concentrations and 0, 1, and 2 g kg-1 dry soil NaCl treatments for 10 weeks. AM symbiosis increased the leaf area and stomatal density (SD) of the abaxial surface. Stomatal size and the aperture of adaxial and abaxial leaf surfaces were higher in the AM than non-AM plants under elevated CO2 and salinity stress. AM plants showed higher stomatal conductance (g s ) and maximum rate of g s to water vapor (g smax ) compared with non-AM plants. Moreover, leaf water potential (Psi) was increased and carbon isotope discrimination (Delta13C) was decreased by AM colonization, and both were significantly associated with stomatal conductance. The results suggest that AM symbiosis alters stomatal morphology by changing SD and the size of the guard cells and stomatal pores, thereby improving the stomatal conductance and water relations of wheat leaves under combined elevated CO2 and salinity stress.

In the last few decades, the classical, mutational, and molecular breeding approaches have brought about tremendous increase in rice productivity with the development of novel rice varieties. However, stagnation in rice yield has been reported in recent decade owing to several factors including the emergence of pests and phyto pathogens, climate change, and other environmental issues posing great threat to global food security. There is an urgent need to produce more rice and associated cereals to satisfy the mammoth task of feeding a still growing population expected to reach 9.7 billion by 2050. Advances in genomics and emergence of multiple genome-editing technologies through use of engineered site-specific nucleases (SSNs) have revolutionized the field of plant science and agriculture. Among them, the CRISPR/Cas9 system is the most advanced and widely accepted because of its simplicity, robustness, and high efficiency. The availability of huge genomic resources together with a small genome size makes rice more suitable and feasible for genetic manipulation. As such, rice has been increasingly used to test the efficiency of different types of genome editing technologies to study the functions of various genes and demonstrate their potential in genetic improvement. Recently developed approaches including CRISPR/Cpf1 system and base editors have evolved as more efficient and accurate genome editing tools which might accelerate the pace of crop improvement. In the present review, we focus on the genome editing strategies for rice improvement, thereby highlighting the applications and advancements of CRISPR/Cas9 system. This review also sheds light on the role of CRISPR/Cpf1 and base editors in the field of genome editing highlighting major challenges and future implications of these tools in rice improvement. PMID- 30283479 TI - Hydrogen Sulfide Mediates K+ and Na+ Homeostasis in the Roots of Salt-Resistant and Salt-Sensitive Poplar Species Subjected to NaCl Stress. AB - Non-invasive micro-test techniques (NMT) were used to analyze NaCl-altered flux profiles of K+, Na+, and H+ in roots and effects of NaHS (a H2S donor) on root ion fluxes in two contrasting poplar species, Populus euphratica (salt-resistant) and Populus popularis (salt-sensitive). Both poplar species displayed a net K+ efflux after exposure to salt shock (100 mM NaCl), as well as after short-term (24 h), and long-term (LT) (5 days) saline treatment (50 mM NaCl, referred to as salt stress). NaHS (50 MUM) restricted NaCl-induced K+ efflux in roots irrespective of the duration of salt exposure, but K+ efflux was not pronounced in data collected from the LT salt stress treatment of P. euphratica. The NaCl induced K+ efflux was inhibited by a K+ channel blocker, tetraethylammonium chloride (TEA) in P. popularis root samples, but K+ loss increased with a specific inhibitor of plasma membrane (PM) H+-ATPase, sodium orthovanadate, in both poplar species under LT salt stress and NaHS treatment. This indicates that NaCl-induced K+ loss was through depolarization-activated K+ channels. NaHS caused increased Na+ efflux and a corresponding increase in H+ influx for poplar roots subjected to both the short- and LT salt stress. The NaHS-enhanced H+ influx was not significant in P. euphratica samples subjected to short term salt stress. Both sodium orthovanadate and amiloride (a Na+/H+ antiporter inhibitor) effectively inhibited the NaHS-augmented Na+ efflux, indicating that the H2S enhanced Na+ efflux was due to active Na+ exclusion across the PM. We therefore conclude that the beneficial effects of H2S probably arise from upward regulation of the Na+/H+ antiport system (H+ pumps and Na+/H+ antiporters), which promote exchange of Na+ with H+ across the PM and simultaneously restricted the channel mediated K+ loss that activated by membrane depolarization. PMID- 30283480 TI - Hydrogen Sulfide Signaling in Plants: Emerging Roles of Protein Persulfidation. AB - Hydrogen sulfide (H2S) has been largely referred as a toxic gas and environmental hazard, but recent years, it has emerged as an important gas-signaling molecule with effects on multiple physiological processes in both animal and plant systems. The regulatory functions of H2S in plants are involved in important processes such as the modulation of defense responses, plant growth and development, and the regulation of senescence and maturation. The main signaling pathway involving sulfide has been proven to be through protein persulfidation (alternatively called S-sulfhydration), in which the thiol group of cysteine ( SH) in proteins is modified into a persulfide group (-SSH). This modification may cause functional changes in protein activities, structures, and subcellular localizations of the target proteins. New shotgun proteomic approaches and bioinformatic analyses have revealed that persulfidated cysteines regulate important biological processes, highlighting their importance in cell signaling, since about one in 20 proteins in Arabidopsis is persulfidated. During oxidative stress, an increased persulfidation has been reported and speculated that persulfidation is the protective mechanism for protein oxidative damage. Nevertheless, cysteine residues are also oxidized to different post-translational modifications such S-nitrosylation or S-sulfenylation, which seems to be interconvertible. Thus, it must imply a tight cysteine redox regulation essential for cell survival. This review is aimed to focus on the current knowledge of protein persulfidation and addresses the regulation mechanisms that are disclosed based on the knowledge from other cysteine modifications. PMID- 30283481 TI - Molecular Background of Pi Deficiency-Induced Root Hair Growth in Brassica carinata - A Fasciclin-Like Arabinogalactan Protein Is Involved. AB - Formation of longer root hairs under limiting phosphate (P) conditions can increase the inorganic P (Pi) uptake. Here, regulatory candidate genes for Pi deficiency-induced root hair growth were identified by comparison of massive analysis of cDNA ends (MACE) provided expression profiles of two Brassica carinata cultivars (cv.) differing in their root hair response to Pi deficiency: cv. Bale develops longer root hairs under Pi deficiency, but not cv. Bacho. A split-root experiment was conducted for the differentiation between locally and systemically regulated genes. Furthermore, plants were exposed to nitrogen and potassium deficiency to identify P-specific reacting genes. The latter were knocked out by CRISPR/Cas9 and the effect on the root hair length was determined. About 500 genes were differentially expressed under Pi deficiency in cv. Bale, while these genes did not respond to the low P supply in cv. Bacho. Thirty-three candidate genes with a potential regulatory role were selected and the transcriptional regulation of 30 genes was confirmed by quantitative PCR. Only five candidate genes seemed to be either exclusively regulated locally (two) or systemically (three), whereas 25 genes seemed to be involved in both local and systemic signaling pathways. Potassium deficiency affected neither the root hair length nor the expression of the 30 candidate genes. By contrast, both P and nitrogen deficiency increased the root hair length, and both affected the transcript levels in 26 cases. However, four genes reacted specifically to Pi starvation. These genes and, additionally, INORGANIC PHOSPHATE TRANSPORTER 1 (BcPHT1) were targeted by CRISPR/Cas9. However, even if the transcript levels of five of these genes were clearly decreased, FASCICLIN-LIKE ARABINOGALACTAN PROTEIN 1 (BcFLA1) was the only gene whose downregulation reduced the root hair length in transgenic hairy roots under Pi-deficient conditions. To the best of our knowledge, this is the first study describing a fasciclin-like arabinogalactan protein with a predicted role in the Pi deficiency-induced root hair elongation. PMID- 30283482 TI - Filter-Aided Sample Preparation Procedure for Mass Spectrometric Analysis of Plant Histones. AB - Characterization of histone post-translational modifications (PTMs) is still challenging, and robust histone sample preparation is essential for convincing evaluation of PTMs by mass spectrometry. An effective protocol for extracting plant histone proteins must also avoid excessive co-extraction of the numerous potential interfering compounds, including those related to secondary metabolism. Currently, the co-existence of histone marks is addressed mostly by shotgun proteomic analysis following chemical derivatization of histone lysine residues. Here, we report a straightforward approach for plant histone sample preparation for mass spectrometry, based on filter-aided sample preparation coupled with histone propionylation. The approach offers savings in sample handling and preparation time, enables removal of interfering compounds from the sample, and does not require either precipitation or dialysis of histone extract. We show the comparison of two protocol variants for derivatization of histone proteins, in solution propionylation in the vial and propionylation on the filter unit. For both protocols, we obtained identical abundances of post-translationally modified histone peptides. Although shorter time is required for histone protein labeling on the filter unit, in-solution derivatization slightly outweighed filter-based variant by lower data variability. Nevertheless, both protocol variants appear to be efficient and convenient approach for preparation of plant histones for mass spectrometric analysis. PMID- 30283483 TI - Hydrogen Sulfide: A Potent Tool in Postharvest Fruit Biology and Possible Mechanism of Action. AB - Hydrogen sulfide (H2S), an endogenous gaseous molecule, is considered as a signaling agent, in parallel with other low molecular weight reactive substances, mainly hydrogen peroxide (H2O2) and nitric oxide (NO), in various plant systems. New studies are now revealing that the postharvest application of H2S, through H2S donors such as sodium hydrosulfide (NaSH) or sodium sulfide (Na2S), can inhibit fruit ripening and senescence programs in numerous fruits. We discuss here current knowledge on the impact of H2S in postharvest physiology of several climacteric and non-climacteric fruits such as banana, apple, pear, kiwifruit, strawberry, mulberry fruit, and grape. Although there is still a considerable lack of studies establishing the mechanisms by which H2S signaling is linked to fruit metabolism, we highlight several candidate mechanisms, including a putative cross-talk between H2S and ethylene, reactive oxygen and nitrogen species, oxidative/nitrosative stress signaling, sulfate metabolism, and post translational modification of protein cysteine residues (S-sulfhydration) as being functional in this H2S postharvest action. Understanding H2S metabolism and signaling during postharvest storage and the interplay with other key player molecules would therefore provide new, improved strategies for better fruit postharvest storage. To achieve this understanding, postharvest fruit physiology research will need to focus increasingly on the spatial interaction between H2S and ethylene perception as well as on the interplay between S sulfhydration/desulfhydration and S-nitrosylation/denitrosylation under several postharvest conditions. PMID- 30283485 TI - Harnessing Phenotypic Plasticity to Improve Maize Yields. AB - Plants can produce different phenotypes when exposed to different environments. Understanding the genetic basis of these plastic responses is crucial for crop breeding efforts. We discuss two recent studies that suggest that yield plasticity in maize has been under selection but is controlled by different genes than yield. PMID- 30283484 TI - Extremophiles as a Model of a Natural Ecosystem: Transcriptional Coordination of Genes Reveals Distinct Selective Responses of Plants Under Climate Change Scenarios. AB - The goal of this research was to generate networks of co-expressed genes to explore the genomic responses of Rhizophora mangle L. populations to contrasting environments and to use gene network analysis to investigate their capacity for adaptation in the face of historical and future perturbations and climatic changes. RNA sequencing data were generated for R. mangle samples collected under field conditions from contrasting climate zones in the equatorial and subtropical regions of Brazil. A gene co-expression network was constructed using Pearson's correlation coefficient, showing correlations among 78,364 transcriptionally coordinated genes. Each region exhibited two distinct network profiles; genes correlated with the oxidative stress response showed higher relative expression levels in subtropical samples than in equatorial samples, whereas genes correlated with the hyperosmotic salinity response, heat response and UV response had higher expression levels in the equatorial samples than in the subtropical samples. In total, 992 clusters had enriched ontology terms, which suggests that R. mangle is under higher stress in the equatorial region than in the subtropical region. Increased heat may thus pose a substantial risk to species diversity at the center of its distribution range in the Americas. This study, which was performed using trees in natural field conditions, allowed us to associate the specific responses of genes previously described in controlled environments with their responses to the local habitat where the species occurs. The study reveals the effects of contrasting environments on gene expression in R. mangle, shedding light on the different abiotic variables that may contribute to the genetic divergence previously described for the species through the use of simple sequence repeats (SSRs). These effects may result from two fundamental processes in evolution, namely, phenotypic plasticity and natural selection. PMID- 30283486 TI - An Effective Way of Producing Fully Assembled Antibody in Transgenic Tobacco Plants by Linking Heavy and Light Chains via a Self-Cleaving 2A Peptide. AB - Therapeutic monoclonal antibodies (mAbs) have evolved into an important class of effective medicine in treatment of various diseases. Since the antibody molecule consists of two identical heavy chains (HC) and two light chains (LC), each chain encoded by two different genes, their expressions at similar levels are critical for efficient assembly of functional recombinant mAbs. Although the plant-based expression system has been tested to produce fully assembled recombinant mAbs, coordinately expressing HC and LC at similar levels in a transgenic plant remains a challenge. A sequence coding for a foot-and-mouth disease virus (FMDV) 2A peptide has been successfully used to link two or more genes, which enable the translated polyprotein to be "self-cleaved" into individual protein in various genetically modified organisms. In the present study, we exploited the usage of F2A in Ebola virus monoclonal antibody (EBOV mAb) production. We found that transgenic tobacco plants carrying a transcription unit containing HC and LC linked by 2A not only produced similar levels of HC and LC but also rendered a higher yield of fully assembled EBOV mAb compared to those expressing HC and LC in two independent transcription units. Purified EBOV mAb bound to an Ebola epitope peptide with apparent Kd -values of 90.13-149.2 nM, indicating its proper assembly and high affinity binding to Ebola epitope peptide. To our knowledge, this is the first report showing mAb production by overexpressing a single transcription unit consisting of HC, LC and 2A in stable transformed tobacco plants. PMID- 30283488 TI - Production of Low-Potassium Content Melon Through Hydroponic Nutrient Management Using Perlite Substrate. AB - Chronic kidney disease patients are restricted to foods with high potassium content but our daily diets including melon are rich in potassium. Therefore, we investigated the production of low-potassium melon through hydroponic nutrient management in soilless culture using perlite substrate during autumn season of 2012, 2014 and spring season of 2016. In the first study, melon plants were supplied with 50% standard 'Enshi' nutrient solution until first 2 weeks of culture. In 3rd and 4th week, amount of applied potassium was 50, 75, 100, and 125% of required potassium nitrate for each plant per week (based on our previous study). It was found that, melon plants grown with 50% of its required potassium nitrate produced fruits with about 53% low-potassium compared to control. In the following study, four cultivars viz. Panna, Miyabi shunjuukei, Miyabi akifuyu412, and Miyabi soushun banshun309 were evaluated for their relative suitability of low-potassium melon production. Results showed insignificant difference in fruit potassium content among the cultivars used. Source of potassium fertilizer as potassium nitrate and potassium sulfate and their restriction (from 1 or 2 weeks after anthesis) were also studied. There were no influences on fruit potassium content and yield due to sources of potassium fertilizer and restriction timings. In our previous studies, it was evident that potassium can be translocated from leaves to fruits at maturity when it was supplied nutrient without potassium. Thus, we also studied total number of leaves per plant (23, 24, 25, 26, and 27 leaves per plant). It was evident that fruit potassium, yield, and quality were not influenced significantly due to differences in number of leaves per plant. These studies showed that restriction of potassium nitrate in the culture solution from anthesis to harvest could produce melon fruits with low-potassium (>20%) content compared to potassium content of greenhouse grown melon (340 mg/100 g FW). Quality testing and clinical validation of low-potassium melon also showed positive responses compared to greenhouse grown melon. PMID- 30283489 TI - Characterization of Fructan Metabolism During Jerusalem Artichoke (Helianthus tuberosus L.) Germination. AB - The inulin-type fructans in Jerusalem artichoke (Helianthus tuberosus L.) tubers exhibit different degrees of polymerization and are critical for germination. We aimed to characterize the sugar metabolism dynamics in the tubers without bud eyes or shoots (T) and BE/S of indoor- and field-grown Jerusalem artichokes during germination. Ht1-FEH II and Ht1-FEH III (1-fructan exohydrolases II and III, inulin-degrading enzymes) expression increased 5 days after planting indoors, whereas Ht1-FEH II expression increased 72 days after planting in the field in T and BE/S. Ht1-SST (sucrose:sucrose 1-fructosyl transferase, inulin synthesis initiator), and Ht1-FFT (fructan:fructan 1-fructosyl transferase, inulin elongator) expression generally decreased in indoor-grown T. The enzyme activities of 1-FEH and 1-FFT were unchanged during germination in both indoor- and field-grown T and BE/S, whereas 1-SST activity decreased in indoor-grown T, while 1-FEH and 1-FFT activities increased as a function of germination time in BE/S of both indoor- and field-grown tubers. The total soluble sugar content gradually decreased in T after germination indoors or in the field, while at the end of germination, the sucrose and fructan contents decreased, and fructose content increased in the field. The enzyme activities of soluble vacuolar (VI) or neutral invertase (NI) did not change significantly, except at the late germination stage. Sucrose synthase (SS) and sucrose-phosphate synthase (SPS) activities were not significantly changed in T and BE/S in indoor-grown artichokes, while SS activity gradually increased, and SPS activity gradually decreased in field-grown artichokes, alongside sucrose degradation. Compared to T, BE/S generally had higher enzyme activities of 1-FEH and 1-FFT, promoting inulin hydrolysis. This work shows that the process of tuber germination is similar indoors and in the field, and germination studies can therefore be conducted in either environment. PMID- 30283487 TI - The Role of Persulfide Metabolism During Arabidopsis Seed Development Under Light and Dark Conditions. AB - The sulfur dioxygenase ETHE1 oxidizes persulfides in the mitochondrial matrix and is involved in the degradation of L-cysteine and hydrogen sulfide. ETHE1 has an essential but as yet undefined function in early embryo development of Arabidopsis thaliana. In leaves, ETHE1 is strongly induced by extended darkness and participates in the use of amino acids as alternative respiratory substrates during carbohydrate starvation. Thus, we tested the effect of darkness on seed development in an ETHE1 deficient mutant in comparison to the wild type. Since ETHE1 knock-out is embryo lethal, the knock-down line ethe1-1 with about 1% residual sulfur dioxygenase activity was used for this study. We performed phenotypic analysis, metabolite profiling and comparative proteomics in order to investigate the general effect of extended darkness on seed metabolism and further define the specific function of the mitochondrial sulfur dioxygenase ETHE1 in seeds. Shading of the siliques had no morphological effect on embryogenesis in wild type plants. However, the developmental delay that was already visible in ethe1-1 seeds under control conditions was further enhanced in the darkness. Dark conditions strongly affected seed quality parameters of both wild type and mutant plants. The effect of ETHE1 knock-down on amino acid profiles was clearly different from that found in leaves indicating that in seeds persulfide oxidation interacts with alanine and glycine rather than branched chain amino acid metabolism. Sulfur dioxygenase deficiency led to defects in endosperm development possibly due to alterations in the cellularization process. In addition, we provide evidence for a potential role of persulfide metabolism in abscisic acid (ABA) signal transduction in seeds. We conclude that the knock-down of ETHE1 causes metabolic re-arrangements in seeds that differ from those in leaves. Putative mechanisms that cause the aberrant endosperm and embryo development are discussed. PMID- 30283490 TI - Characterization and Expression Patterns of Auxin Response Factors in Wheat. AB - Auxin response factors (ARFs) are important transcription factors involved in both the auxin signaling pathway and the regulatory development of various plant organs. In this study, 23 TaARF members encoded by a total of 68 homeoalleles were isolated from 18 wheat chromosomes (excluding chromosome 4). The TaARFs, including their conserved domains, exon/intron structures, related microRNAs, and alternative splicing (AS) variants, were then characterized. Phylogenetic analysis revealed that members of the TaARF family share close homology with ARFs in other grass species. qRT-PCR analyses revealed that 20 TaARF members were expressed in different organs and tissues and that the expression of some members significantly differed in the roots, stems, and leaves of wheat seedlings in response to exogenous auxin treatment. Moreover, protein network analyses and co expression results showed that TaTIR1-TaARF15/18/19-TaIAA13 may interact at both the protein and genetic levels. The results of subsequent evolutionary analyses showed that three transcripts of TaARF15 in the A subgenome of wheat exhibited high evolutionary rate and underwent positive selection. Transgenic analyses indicated that TaARF15-A.1 promoted the growth of roots and leaves of Arabidopsis thaliana and was upregulated in the overexpression plants after auxin treatment. Our results will provide reference information for subsequent research and utilization of the TaARF gene family. PMID- 30283491 TI - De novo Assembly and Transcriptome Characterization of Opisthopappus (Asteraceae) for Population Differentiation and Adaption. AB - Opisthopappus Shih (Asteraceae), an endangered genus endemic to the Taihang Mountains of China, is a high-value ornamental and medicinal plant consisting of two species, Opisthopappus longilobus shih and Opisthopappus taihangensis (Ling) Shih. However, the evolutionary relationships and the taxonomic characteristics between the two species remain unknown. In this study, high-throughput transcriptome sequencing was used to analyze the differential metabolic activity and gene expression and screened special molecular markers for exploring the genetic variation and species differentiation in Opisthopappus Shih. The results showed that 33,974 unigenes with an average size of 801 bp were obtained with optimization of de novo assembly. The comprehensive functional annotation based on Gene Ontology (GO), Cluster of Orthologous Group (COG) and Kyoto Encyclopedia of Genes and Genomes pathway database (KEGG) revealed that these unigenes were mainly related to many physiological, metabolic, and molecular processes. Furthermore, the comparative transcriptome analysis indicated that 3,410 differentially expressed genes were mainly involved in lipid, carbohydrate and amino acid metabolism, xenobiotics biodegradation and metabolism as well as environment adaptation via KEGG. Such as the CYP710A, GST, HSP90A and so on, could be the potential candidate genes for further investigating the molecular mechanism of physiological variations between O. taihangensis and O. longilobus. In addition, the potential 71,804 high quality single nucleotide polymorphisms (SNPs) and 1,444 simple sequence repeats (SSRs) were estimated. Based on the predicted SNP, we have developed eight SNP markers for population genetic analysis in Opisthopappus Shih. A significantly high level of genetic differentiation between the populations of O. longilobus and O. taihangensis were found, and they were clearly grouped into two distinct genetic clusters. These results conformed to the record of Flora Reipublicae Popularis Sinicae (FRPS) and unsupported the taxonomic status in the Flora of China. The transcriptome analysis of Opisthopappus Shih can contribute to in-depth exploring of internal mechanisms in species variation and differentiation based on molecular evidence. With the rich and valuable data resources, the more novel structural, functional, and comparative genomic studies will provide comprehensive insights into the evolutionary relationships between O. taihangensis and O. longilobus. PMID- 30283493 TI - Genome-Wide and Trait-Specific Markers: A Perspective in Designing Conservation Programs. AB - Nowadays, breed conservation has entered the genomics era and it is imperative to develop novel theory to design the breeding schemes of the conservation populations by using the genomic information. The genome-wide markers have been regarded as a useful strategy to maintain genetic diversity. However, using the genome-wide SNPs to optimize diversity might not be optimal for some specific loci associated with specific-traits. Using the sequencing data of the conserved population of the Saba pig breed, we demonstrated that the conservation program designed by using the genome-wide SNPs might result in the loss of the genetic diversity of the reproduction trait. We suggested an idea of using phylogenetic tree to select valuable individuals for conservation program based on the genome wide and trait-specific makers. The selection rule was to make the selected samples to be widely distributed as much as possible in both the genome-wide and trait-specific phylogenetic trees. PMID- 30283492 TI - Genome-Wide Association Analysis With a 50K Transcribed Gene SNP-Chip Identifies QTL Affecting Muscle Yield in Rainbow Trout. AB - Detection of coding/functional SNPs that change the biological function of a gene may lead to identification of putative causative alleles within QTL regions and discovery of genetic markers with large effects on phenotypes. This study has two fold objectives, first to develop, and validate a 50K transcribed gene SNP-chip using RNA-Seq data. To achieve this objective, two bioinformatics pipelines, GATK and SAMtools, were used to identify ~21K transcribed SNPs with allelic imbalances associated with important aquaculture production traits including body weight, muscle yield, muscle fat content, shear force, and whiteness in addition to resistance/susceptibility to bacterial cold-water disease (BCWD). SNPs ere identified from pooled RNA-Seq data collected from ~620 fish, representing 98 families from growth- and 54 families from BCWD-selected lines with divergent phenotypes. In addition, ~29K transcribed SNPs without allelic-imbalances were strategically added to build a 50K Affymetrix SNP-chip. SNPs selected included two SNPs per gene from 14K genes and ~5K non-synonymous SNPs. The SNP-chip was used to genotype 1728 fish. The average SNP calling-rate for samples passing quality control (QC; 1,641 fish) was >= 98.5%. The second objective of this study was to test the feasibility of using the new SNP-chip in GWA (Genome-wide association) analysis to identify QTL explaining muscle yield variance. GWA study on 878 fish (representing 197 families from 2 consecutive generations) with muscle yield phenotypes and genotyped for 35K polymorphic markers (passing QC) identified several QTL regions explaining together up to 28.40% of the additive genetic variance for muscle yield in this rainbow trout population. The most significant QTLs were on chromosomes 14 and 16 with 12.71 and 10.49% of the genetic variance, respectively. Many of the annotated genes in the QTL regions were previously reported as important regulators of muscle development and cell signaling. No major QTLs were identified in a previous GWA study using a 57K genomic SNP chip on the same fish population. These results indicate improved detection power of the transcribed gene SNP-chip in the target trait and population, allowing identification of large-effect QTLs for important traits in rainbow trout. PMID- 30283494 TI - Genomic Selection for Growth Traits in Pacific Oyster (Crassostrea gigas): Potential of Low-Density Marker Panels for Breeding Value Prediction. AB - Pacific oysters are a key aquaculture species globally, and genetic improvement via selective breeding is a major target. Genomic selection has the potential to expedite genetic gain for key target traits of a breeding program, but has not yet been evaluated in oyster. The recent development of SNP arrays for Pacific oyster (Crassostrea gigas) raises the opportunity to test genomic selection strategies for polygenic traits. In this study, a population of 820 oysters (comprising 23 full-sibling families) were genotyped using a medium density SNP array (23 K informative SNPs), and the genetic architecture of growth-related traits [shell height (SH), shell length (SL), and wet weight (WW)] was evaluated. Heritability was estimated to be moderate for the three traits (0.26 +/- 0.06 for SH, 0.23 +/- 0.06 for SL and 0.35 +/- 0.05 for WW), and results of a GWAS indicated that the underlying genetic architecture was polygenic. Genomic prediction approaches were used to estimate breeding values for growth, and compared to pedigree based approaches. The accuracy of the genomic prediction models (GBLUP) outperformed the traditional pedigree approach (PBLUP) by ~25% for SL and WW, and ~30% for SH. Further, reduction in SNP marker density had little impact on prediction accuracy, even when density was reduced to a few hundred SNPs. These results suggest that the use of genomic selection in oyster breeding could offer benefits for the selection of breeding candidates to improve complex economic traits at relatively modest cost. PMID- 30283495 TI - Genome Sequence of Peacock Reveals the Peculiar Case of a Glittering Bird. AB - The unique ornamental features and extreme sexual traits of Peacock have always intrigued scientists and naturalists for centuries. However, the genomic basis of these phenotypes are yet unknown. Here, we report the first genome sequence and comparative analysis of peacock with the high quality genomes of chicken, turkey, duck, flycatcher and zebra finch. Genes involved in early developmental pathways including TGF-beta, BMP, and Wnt signaling, which have been shown to be involved in feather patterning, bone morphogenesis, and skeletal muscle development, revealed signs of adaptive evolution and provided useful clues on the phenotypes of peacock. Innate and adaptive immune genes involved in complement system and T cell response also showed signs of adaptive evolution in peacock suggesting their possible role in building a robust immune system which is consistent with the predictions of the Hamilton-Zuk hypothesis. This study provides novel genomic and evolutionary insights into the molecular understanding toward the phenotypic evolution of Indian peacock. PMID- 30283496 TI - Reciprocal Regulation of Metabolic Reprogramming and Epigenetic Modifications in Cancer. AB - Cancer cells reprogram their metabolism to meet their demands for survival and proliferation. The metabolic plasticity of tumor cells help them adjust to changes in the availability and utilization of nutrients in the microenvironment. Recent studies revealed that many metabolites and metabolic enzymes have non metabolic functions contributing to tumorigenesis. One major function is regulating epigenetic modifications to facilitate appropriate responses to environmental cues. Accumulating evidence showed that epigenetic modifications could in turn alter metabolism in tumors. Although a comprehensive understanding of the reciprocal connection between metabolic and epigenetic rewiring in cancer is lacking, some conceptual advances have been made. Understanding the link between metabolism and epigenetic modifications in cancer cells will shed lights on the development of more effective cancer therapies. PMID- 30283498 TI - Aspergillus flavus resident in Kenya: High genetic diversity in an ancient population primarily shaped by clonal reproduction and mutation-driven evolution. AB - Aspergillus flavus has long been considered to be an asexual species. Although a sexual stage was recently reported for this species from in vitro studies, the amount of recombination ongoing in natural populations and the genetic distance across which meiosis occurs is largely unknown. In the current study, genetic diversity, reproduction and evolution of natural A. flavus populations endemic to Kenya were examined. A total of 2744 isolates recovered from 629 maize-field soils across southern Kenya in two consecutive seasons were characterized at 17 SSR loci, revealing high genetic diversity (9-72 alleles/locus and 2140 haplotypes). Clonal reproduction and persistence of clonal lineages predominated, with many identical haplotypes occurring in multiple soil samples and both seasons. Genetic analyses predicted three distinct lineages with linkage disequilibrium and evolutionary relationships among haplotypes within each lineage suggesting mutation-driven evolution followed by clonal reproduction. Low genetic differentiation among adjacent communities reflected frequent short distance dispersal. PMID- 30283497 TI - Functional Interaction Between BRCA1 and DNA Repair in Yeast May Uncover a Role of RAD50, RAD51, MRE11A, and MSH6 Somatic Variants in Cancer Development. AB - In this study, we determined if BRCA1 partners involved in DNA double-strand break (DSB) and mismatch repair (MMR) may contribute to breast and ovarian cancer development. Taking advantage the functional conservation of DNA repair pathways between yeast and human, we expressed several BRCA1 missense variants in DNA repair yeast mutants to identify functional interaction between BRCA1 and DNA repair in BRCA1-induced genome instability. The pathogenic p.C61G, pA1708E, p.M775R, and p.I1766S, and the neutral pS1512I BRCA1 variants increased intra chromosomal recombination in the DNA-repair proficient strain RSY6. In the mre11, rad50, rad51, and msh6 deletion strains, the BRCA1 variants p.C61G, pA1708E, p.M775R, p.I1766S, and pS1215I did not increase intra-chromosomal recombination suggesting that a functional DNA repair pathway is necessary for BRCA1 variants to determine genome instability. The pathogenic p.C61G and p.I1766S and the neutral p.N132K, p.Y179C, and p.N550H variants induced a significant increase of reversion in the msh2Delta strain; the neutral p.Y179C and the pathogenic p.I1766S variant induced gene reversion also, in the msh6Delta strain. These results imply a functional interaction between MMR and BRCA1 in modulating genome instability. We also performed a somatic mutational screening of MSH6, RAD50, MRE11A, and RAD51 genes in tumor samples from 34 patients and identified eight pathogenic or predicted pathogenic rare missense variants: four in MSH6, one in RAD50, one in MRE11A, and two in RAD51. Although we found no correlation between BRCA1 status and these somatic DNA repair variants, this study suggests that somatic missense variants in DNA repair genes may contribute to breast and ovarian tumor development. PMID- 30283499 TI - Rifaximin has the potential to prevent complications of cirrhosis. AB - Background: Cirrhosis-related complications are associated with poor prognosis. With our analyses, we examined the potential benefit of rifaximin in reducing the risk of developing cirrhosis-related complications. Methods: Adults with cirrhosis and hepatic encephalopathy (HE) in remission were randomly assigned to receive rifaximin 550 mg twice daily or placebo for 6 months with concomitant lactulose permitted. Post hoc analyses examined time to cirrhosis-related complications (HE, spontaneous bacterial peritonitis (SBP), variceal bleeding, acute kidney injury/hepatorenal syndrome). Subgroup analyses evaluated efficacy for select baseline disease characteristics. Results: Of patients receiving rifaximin (n = 140) and placebo (n = 159), 53.6% and 49.1%, respectively, had baseline Model for End-Stage Liver Disease (MELD) score ? 12 and international normalized ratio (INR) ? 1.2. Baseline ascites was observed in 36.4% (rifaximin) and 34.6% (placebo) of patients. In patients with MELD score ? 12 and INR ? 1.2, rifaximin reduced the relative risk (RR) of any first complication experienced during trial by 59% [hazard ratio (HR) = 0.41, 95% confidence interval (CI): 0.25 0.67; p < 0.001] versus placebo. For patients with baseline ascites, rifaximin reduced the RR of any first complication experienced during trial by 42% versus placebo (HR = 0.58, 95% CI: 0.34-1.0; p = 0.045). For some subgroups, there was a decrease in RR of complications of SBP, variceal bleeding, and acute kidney injury/hepatorenal syndrome with rifaximin versus placebo, although there were few events reported in the study. Conclusion: Rifaximin may reduce the incidence of cirrhosis-related complications and the recurrence of overt HE.[ClinicalTrials.gov identifier: NCT00298038.]. PMID- 30283501 TI - Design and development of a biorelevant simulated human lung fluid. AB - Biorelevant fluids are required to enable meaningful in vitro experimental determinations of the biopharmaceutical properties of inhaled medicines, e.g. drug solubility, particle dissolution, cellular uptake. Our aim was to develop a biorelevant simulated lung fluid (SLF) with a well-defined composition and evidence-based directions for use. The SLF contained dipalmitoylphosphotidylcholine, dipalmitoylphosphatidylglycerol, cholesterol, albumin, IgG, transferrin and antioxidants. Freshly made SLF had pH 7.2, viscosity 1.138 * 10-3 Pa s, conductivity 14.5 mS/m, surface tension 54.9 mN/m and density 0.999 g/cm3. Colour, surface tension and conductivity were the most sensitive indicators of product deterioration. The simulant was stable for 24 h and 48 h at 37 degrees C and 21 degrees C, respectively, (in-use stability) and for 14 days when stored in a refrigerator (storage stability). To extend stability, the SLF was vacuum freeze-dried in batches to produce lyophilised powder that can be reconstituted readily when needed at the point of use. In conclusion, we have reported the composition and manufacture of a biorelevant, synthetic SLF, provided a detailed physico-chemical characterisation and recommendations for how to store and use a product that can be used to generate experimental data to provide inputs to computational models that predict drug bioavailability in the lungs. PMID- 30283500 TI - Choices for long-term hypertensive control in patients after first-ever hemorrhagic stroke: a nationwide cohort study. AB - Background: To compare the long-term clinical outcomes of different antihypertensive drugs in stable patients after acute hemorrhagic stroke (HS). Methods: From January 2001 to December 2013, patients with first-ever primary HS were identified in the National Health Insurance Research Database, Taiwan. Patients with traumatic intracerebral hemorrhage and secondary HS were excluded. Those with first-ever HS were recruited and classified into three groups: (1) angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB); (2) calcium channel blocker (CCB); and (3) other antihypertensive drugs (comparison) groups. Propensity score matching was used to balance the distribution of baseline characteristics, stroke severity, and medications between any two of the three groups. A validation study was performed using the databank of the Stroke Registry in Chang-Gung Healthcare System to reduce the bias. Primary outcomes were recurrent HS, ischemic stroke, any stroke, and all cause mortality. Results: Compared to the comparison group, the ACEI/ARB group [35.4% versus 39.3%; hazard ratio (HR), 0.84; 95% confidence interval (CI), 0.74 0.95] and CCB group (33.0% versus 41.9%; HR, 0.72; 95% CI, 0.64-0.81) had a lower risk of all-cause mortality during long-term follow up. The CCB group had a similar risk of all-cause mortality to the ACEI/ARB group. Risks of recurrent HS, ischemic stroke, or any stroke were not different between the study groups. Conclusions: Antihypertensive drug class could be important to long-term outcomes in HS patients in addition to the target control of blood pressure. Both ACEIs/ARBs and CCBs are associated with lower risks of all-cause mortality. Our results may be applied to inform future research on hypertensive control in HS patients. PMID- 30283502 TI - Adenosine-induced Flow Arrest to Facilitate Intracranial Complex Aneurysm Clip Ligation: Review of the Literature. AB - Complex intracranial aneurysms (CIAs) rank high among the most technically demanding neurosurgical pathologies. Microsurgery and clip ligation can be challenging in CIAs as circumferential visualization of the aneurysm, parent vessels, branches, perforators, and other neurovascular structures is important to prevent residual aneurysms or strokes from vessel or perforator occlusion. Decompression of the aneurysm sac is often required for CIAs. We reviewed the literature and PubMed advanced search showed 13 results of adenosine-induced flow arrest to facilitate intracranial complex aneurysm clip ligation which included three independent case reports and ten cases in a case series from 1999 to May 2016. Few case series have described the use of adenosine in intracranial aneurysm surgery. Satisfactory aneurysm decompression was achieved in all cases, and all aneurysms were clipped successfully. We recommend that adenosine cardiac arrest is a relatively novel method for decompression of intracranial aneurysms to facilitate clip application. With appropriate safety precautions, it is a reasonable alternative method when temporary clipping of proximal vessels is not desirable or not possible. PMID- 30283504 TI - Recovery of Oculomotor Nerve Palsy after Endovascular and Surgical Treatment of Posterior Communicating Artery Aneurysms: A Single Institutional Experience. AB - Introduction: Surgical oculomotor nerve palsy(ONP), defined by ptosis, ophthalmoplegia, diplopia and pupillary dilatation, is associated with intracranial aneurysms, especially posterior communicating artery (PcomA) aneurysms. Treatment of PcomA aneurysms include endovascular coiling and surgical clipping. This study retrospectively compared the recovery of ONP in patients who underwent endovascular coiling or surgical clipping. Methods: A retrospective review of patients with PcomA aneurysms who presented with ONP between 1998 and 2012 in the National Neuroscience Institute, Singapore, was performed. Inclusion criteria included adult patients of age above 21 who have radiologically confirmed PcomA aneurysms with presentation of ipsilateral ONP. The aneurysms may be unruptured or ruptured with WFNS grade 2 subarachnoid hemorrhage (SAH) or better. Only patients with completely surgically or endovascularly obliterated PcomA aneurysms with regular follow-up are included. Results: A total of 22 patients were recruited. They were treated by either endovascular coiling or surgical clipping. The two groups of patients were demographically comparable, with 11 patients in each arm. 13 (59%) patients had unruptured aneurysms and 9 (41%) had WFNS grade 2 or better SAH. 13 (59%) patients presented with complete ONP and 9 (41%) had partial ONP. 64% of patients who underwent surgical clipping had resolution of ONP completely, compared to 18% of endovascularly coiling (P = 0.03) at 1-month follow-up. Conclusion: Compared to endovascular coiling, surgically clipped PcomA aneurysms are associated with a faster rate of full recovery of ONP. PMID- 30283505 TI - Pituitary Adenoma Apoplexy: Review of Personal Series. AB - Background: Pituitary apoplexy is a life-threatening event with unspecific clinical background and no standardized treatment. Materials and Methods: The authors retrospectively analyzed seventeen patients affected by pituitary adenoma apoplexy and treated in a 10-year period. Thirteen patients underwent surgery through transsphenoidal route while four patients have been treated conservatively. Results: The endoscopic surgical procedure showed a better result in term of complete removal of the tumor while in the "conservative" group less frequent evidence of hormones' deficiency has been registered. Once a residual lesions was observed a strict radiological follow-up is mandatory. Conclusions: According to dedicated literature and pre- and post-operative evidence of personal series, the authors try to provide an algorithm that could help in the standardization of the diagnostic and therapeutic pathways in patients with pituitary adenoma apoplexy. PMID- 30283503 TI - Contemporary Updates on Clinical Trials of Antiangiogenic Agents in the Treatment of Glioblastoma Multiforme. AB - Glioblastoma multiforme (GBM) has the highest rate of vascular proliferation among solid tumors. Angiogenesis is the central feature of rapid tumor growth in GBM and therefore remains an appealing therapeutic target in the treatment of these highly malignant tumors. Antiangiogenic therapy is emerging as an important adjuvant treatment. Multiple antiangiogenic agents targeting various sites in vascular endothelial growth factor (VEGF) and integrin pathways have been tested in clinical trials of newly diagnosed and recurrent GBMs. These include bevacizumab, enzastaurin, aflibercept, cediranib, and cilengitide. In this review, we discuss the current status and challenges facing clinical application of antiangiogenic treatment including anti-VEGF therapy and integrin pathway agents' therapy in glioblastoma. Here, we highlight a strong biologic rationale for this strategy, also focusing on integrin pathways. PubMed-indexed clinical trials published in English on antiangiogenic treatment of glioblastomas in the past 5 years were reviewed. The results of the current clinical trials of these agents are presented. PMID- 30283506 TI - Acute Subdural Hematoma Evacuation: Predictive Factors of Outcome. AB - Background: Acute subdural hematoma (aSDH) is a major cause of admission at Neurosurgical Emergency Department. Nevertheless, concerns regarding surgical indication in patients with multiple comorbidities, poor neurological status, antithrombotic therapy, and older age still persist. Therefore, a correct recognition of predictive outcome factors at hospital discharge is crucial to an appropriate neurosurgical treatment. Methods: Eighty-nine medical records of consecutive patients with age >=18 years old who were submitted to aSDH evacuation between January 2008 and May 2012 were reviewed. Demographic characteristics, neurological status on admission, anticoagulant or antiplatelet therapy, and outcome on discharge were collected. Patients with insufficient data concerning these variables were excluded from the study. Results: Sixty-nine patients were included; 52% were male; 74% were older than 65 years; 41% were under oral antithrombotic therapy (OAT); at admission, 54% presented with Glasgow coma scale (GCS) <=8; 23% were submitted to a craniectomy instead of a craniotomy; 26% of the patients died, 32% were dependent, and 42% were independent on discharge. Crude analysis revealed craniectomy, A/A pupils, GCS <=8 at admission statistically significant related with the worst outcome (P < 0.05). In the adjusted evaluation only A/A pupils (P = 0.04) was associated to poor outcome (spontaneous etiology P = 0.052). Considering daily living independency at hospital discharge, either male gender (P = 0.044) and A/A pupils (P = 0.030) were related to the worst outcome. No effect of age in outcome was observed. Conclusions: Male gender and A/A pupils are associated with lower probability of achieving independency living at hospital discharge. A/A pupils, low GCS at admission, spontaneous etiology, and craniectomy were associated with the worst outcome. Age and OAT were not predictive factors in this series. Caution should be taken when considering these factors in the surgical decision. PMID- 30283507 TI - Relationship between Abducens Nerve Palsy and Local Hematoma in a Case Series of Ruptured Vertebral Artery Dissecting Aneurysm. AB - Background: Abducens nerve palsy associated with subarachnoid hemorrhage (SAH) has rarely been reported. Its frequency, mechanism of palsy, association with aneurysmal location, and clinical course are poorly described. The purpose of our study was to evaluate patients with abducens nerve palsy caused by SAH occurring from ruptured vertebral artery (VA) dissecting aneurysm and to find aneurysmal location using initial computed tomography (CT) and its association with clinically detected cranial nerve palsy. Methods: Fourteen patients of SAH due to ruptured VA dissecting aneurysm were treated at our hospital from January 2011 to May 2015. The clinical courses and CT findings were reviewed retrospectively. Results: Abducens nerve palsy was observed in 77.8% of cases after excluding patients with decreased levels of consciousness. Clots within the prepontine cistern were significantly thicker in cases of VA dissecting aneurysm than in case of supratentorial aneurysm (P = 0.002). Conclusion: The findings of our study indicated that ruptured VA dissecting aneurysms, even in cases of angio negative SAH, are likely to present with abducens nerve palsy. PMID- 30283508 TI - Utility of Computed Tomography-guided Biopsy in Evaluation of Metastatic Spinal Lesions. AB - Introduction: Computed tomography (CT)-guided biopsy of spine is currently a valuable diagnostic tool and effective technique for diagnosing and planning a proper therapeutic strategy for certain spinal lesions. The reported diagnostic accuracy of core biopsy ranges from 77% to 97%. Materials and Methods: We included all patients with spinal lesions suspicious of metastasis on magnetic resonance imaging, who presented between May 2012 and April 2014 and underwent CT guided biopsy in our study. A total of thirty patients with spinal lesions were evaluated. Results: Majority presented in the seventh decade of their life (average age = 53.93; age range = 10-72 years). Male:female ratio was 1.5:1. Pain was the most common presenting symptom (100%). Lumbar spine was the most common site of lesion followed by dorsal spine. Biopsy is the gold standard in histopathological evaluation of spinal lesions. Metastatic lesion was diagnosed in 12 (40%) cases, plasmacytoma in 12 (40%) cases, non-Hodgkin's lymphoma in 2 (6.66%) cases, small round cell tumor in 1 (3.33%) case, nonspecific chronic inflammation in two patients, and necrosis with no viable cells in one patient. The most common malignancy to metastasize to spine was adenocarcinoma. The most common primary tumor of spine was plasmacytoma - multiple myeloma. Conclusion: CCT-guided biopsy is a safe procedure, and no procedure-related complication was seen in any patient. PMID- 30283509 TI - Evaluation of Role of Electrophysiological Studies in Patients with Lumbar Disc Disease. AB - Background: The role of the electrophysiologic studies in peripheral nerves and muscles of lower limbs (including paraspinal muscles) in prolapsed lumbar intervertebral discs has been studied with equivocal results. Pre- and post operative electrodiagnostic studies have not been compared much. Aims and Objectives: To study the role of the electrophysiologic studies in prolapsed lumbar/lumbosacral intervertebral discs for finding the association between clinical findings and electrophysiological changes and to compare the electrophysiologic studies pre- and post-operatively. Materials and Methods: The study was conducted from July 2014 to June 2016 on fifty patients who were admitted in the department of neurological surgery with lumbar disc prolapse and all these patients were subjected to surgery. Both pre- and post-operative (from 1 to 6 months after surgery) electrophysiological studies were conducted and compared. Results: As per the electromyographic (EMG) abnormalities, the most common levels of intervertebral disc prolapse were L4-L5 and L5-S1 accounting for 32% of cases each followed by L5-S1 level which was seen in 28% of patients with L2-L3, L3-L4, and L4-L5 prolapsed intervertebral disc (PIVD) and L3-L4 and L4-L5 PIVD were seen in 4% of cases each. Of the 50 patients, EMG findings correlated with operative findings in 37 (74%) patients, however operative findings did not correlate with EMG findings in 13 (26%) patients. Conclusion: In compressive lesions of nerve roots (due to disc prolapsed), the EMG method has a high degree of accuracy in determining not only the presence of such lesions but also their exact location. EMG is accurate when correlated with the operative findings. PMID- 30283510 TI - Establishing a Training Model for Side-to-Side Anastomosis using Rat Femoral Vessels: Immediate and Delayed Patency. AB - Introduction: Side-to-side anastomoses are a relatively newer and more difficult technique used in neurovascular surgery for complex aneurysms/lesions. In view of the complex surgical technique and the infrequent clinical opportunities to acquire skills relevant to this surgery, laboratory training assumes great importance. The authors studied the feasibility of establishing a training model for performing side-to-side anastomosis using rat femoral vessels and compared the immediate and delayed patency rates in this animal model. Materials and Methods: After Institutional Animal Ethics Committee clearance, 16 Sprague-Dawley rats were used in this prospective study between August 2013 and March 2015. Using the standard groin incision, the femoral vessels were dissected. After applying temporary clamps, opening of approximately 3-4 mm (at least double the diameter of the wider vessel) of length was made on the facing surfaces of both vessels. 10-0 nylon was used for anastomosis. The clamps were released, and the anastomoses patency confirmed. Leg movements following the anastomoses were studied. The animals were subsequently sacrificed to assess delayed patency. Results: The immediate patency rate was 87.5% (14/16). The delayed patency rate (mean follow-up 209 days) was 53.8% (7/13). Three rats died during the follow-up period. The mean clamp duration and suturing time was 57.25 and 41.50 min in the first eight cases and 57.50 and 36.75 min in the last eight experiments, respectively. Conclusion: This animal model was found to be extremely useful for training in the difficult art of side-to-side anastomoses. The need of the hour is to establish well-planned training programs in centers with animal research facilities and use such models. This will promote younger colleagues and trainees to take up and perfect this difficult art. The present work could be used as a baseline study in this direction. PMID- 30283511 TI - Intraoperative Neurophysiological Monitoring in Surgical Treatment of Spinal Dural Arteriovenous Fistulas: Technique and Results. AB - Objective and Background: Data on intraoperative neurophysiological monitoring (IOM) during surgery of spinal dural arteriovenous fistulas (SDAVFs) are lacking. The purpose of this study was to evaluate the role of IOM during microsurgery for SDAVFs. Materials and Methods: From March 2007 to March 2013, 12 patients had microsurgery with IOM for SDAVFs. The IOM included somatosensory-evoked potentials, motor-evoked potentials (MEPs), and - in selected cases - D-Waves. All patients were evaluated at admission and at follow-up (6, 12, and 24 months) with Aminoff-Logue Disability Scale for Gait-Aminoff-Logue Disability Scale (G ALS) and Micturition-Aminoff-Logue Disability Scale (M-ALS). Statistical Analysis Used: Logistic regression was used for detecting the clinical risk factors influencing neurological functions after the treatment. Results: During surgery, we registered the absence of significant modifications of evoked potentials in nine cases (75%), while improvement of MEPs occurred in three cases (25%). No false-negative case was registered, and IOM predicted the absence of new postoperative neurological deficit in all patients. At 24-month follow-up, nine patients improved their overall neurological status, while three patients remained stable. At univariate analysis, Aminoff-Logue Disability Scales for Gait and Micturition (G + M-ALS) score at 24-month follow-up was directly associated with the duration of symptom before the surgery (P = 0.024), preoperative G-ALS (P = 0.02), M-ALS (P = 0.022), and G + M-ALS scores (P = 0.045), and improvement of IOM after occlusion of the fistula (P = 0.025). Conclusions: In our series, no significant worsening of evoked potentials occurred and subsequently the surgical strategy was not changed by IOM. However, no false-negative case was registered, and IOM predicted the absence of new postoperative neurological deficit in all patients. Patients with improvement of IOM parameters after occlusion of the fistula had greater chances of postsurgical improvement at the univariate analysis. PMID- 30283512 TI - Endoscopic Treatment of Hydrocephalus with Minimal Resources: Resource Utilization and Indigenous Innovation in Developing Countries like India. AB - Context: Neuroendoscopic surgeries need specialized equipments, unavailable in neurosurgical departments of majority of public healthcare institutions of India. Aims: Neuroendoscopic treatment of hydrocephalus in the setting of minimal resources using utilization of available resources, inter-departmental co ordination and indigenous innovations. Methods: Study was carried out at a public sector institute of India with scarce resources. Senior author (DKJ) used indigenously designed stainless steel working sheath along with equipments of 'awake endoscopic intubation system' of department of neuroanesthesia and 18 cm, 4 mm, 0 degrees rigid telescope for neuroendoscopic surgeries for various intraventricular pathologies. Results: Thirty-four neuroendoscopic surgeries in 32 patients were done over last 3 years. There were 18 males and 14 females with average age of 23 years. It included hydrocephalus due to tubercular meningitis (n = 19), neurocysticercosis (NCC) (n = 4), intra-ventricular (n = 2) and para ventricular (n = 2) space occupying lesions, aqueduct stenosis with (n = 2) or without (n = 1) shunt malfunction and one case each of pyogenic meningitis and right cerebellar infarction. Endoscopic third ventriculostomy (ETV) (n = 28), septostomy (n = 6), removals of cystic lesions (n = 3) and biopsies of intraventricular lesions (n = 2) were done in a total of 34 neuroendoscopic surgeries. Overall there were four failures of ETVs, which were managed by ventriculo-peritoneal shunts. Two mortalities in the study group were unrelated to the surgical procedures. Conclusion: Indigenous innovations and interdisciplinary co-ordination are the way ahead to tackle resource scarcity in public sector healthcare institutions of India in the scenario of plenty of neuroendoscopic trainings opportunities for young neurosurgeons and paucity of equipments required. PMID- 30283513 TI - Efficacy of Double Drug Impregnated Autologous Coagulum Patch versus Single Drug Impregnated Autologous Coagulum Patch in Postoperative Pain Management after Spinal Surgery. AB - Background: Postoperative pain and cerebrospinal fluid (CSF) leak are common known complications of spinal surgery, both having a synergistic effect on each other. Thus, both need to be dealt simultaneously. Double drug impregnated autologous coagulum patch (DDIAC) is a novel method which reduced both incidences of postoperative CSF leaks as well as pain. Methodology: Twenty-seven patients undergoing lumbar disc surgery without instrumentation were included and randomized into DDIAC and single drug impregnated autologous coagulum patch (SDIAC) group. The patients were assessed postoperatively with visual analog scale (VAS). Results: There were 21 males and 6 females in the study. Seventeen (63%) patients got randomized for DDIAC patch application and other 10 (37%) patients entered the control arm group (SDIAC) patch use. Preoperative VAS was 5 in both the groups. The average postoperative VAS was 3.01 in DDIAC arm and 4.29 in control arm. The average analgesic shot required in the DDIAC group was 0.41 in 24 h and SDIAC group was 4.1 in 24 h. In DDIAC group, none of these patients had CSF leak from the surgical wound till discharge from the hospital. In the SDIAC group, one (10%, n = 10) patient had CSF leak. Conclusions: DDIAC patch was effective in controlling pain in the postoperative period; however, few patients may require analgesic shots for pain management. SDIAC patch may control some pain in the immediate postoperative period; however, this was not sufficient for a longer postoperative period. PMID- 30283514 TI - Relationship between the Volume Rate of Ed Coil (Ed Ratio) and Packing Density in Endosaccular Embolization of Cerebral Aneurysms. AB - Purpose: A high packing density (PD) (i.e., coil volume per aneurysm volume) helps prevent recanalization after endosaccular embolization of cerebral aneurysms. We hypothesized that the use of soft coils may be useful to raise PD and retrospectively investigated the correlation between the ED coil volume rate (i.e., volume ratio of all placed coils) and PD in patients treated with endosaccular embolization using this coil. Methods: Excluding aneurysms treated with a stent, 292 aneurysms treated using ED coils were included in this study. The 292 aneurysms and aneurysms with >=30%, >=40%, and >=50% ED coil volume rates (202, 168, and 129 aneurysms, respectively) underwent linear regression analysis of the following seven factors' influence on PD:ED ratio, aneurysm volume, neck width, height, maximum diameter, dome-to-neck ratio, and aspect ratio. Results: Independent factors of a high PD were high ED ratio and small neck width on analyses of aneurysms with an ED ratio of >=40% and >=50%. Only neck width was an independent factor on analyses of all 292 aneurysms and aneurysms with ED ratio of >=30%. Conclusion: The use of ED coils in high volume rate correlated with a high PD and may contribute to prevent recanalization in small aneurysms. PMID- 30283515 TI - Gravity-guided Stereotactic Brain Biopsy. AB - Introduction: This study describes a technique using gravity for guidance in stereotactic brain biopsy. This will be especially useful in hospitals where the stereotactic equipment is unavailable. Objectives: The aim of this study is to describe the technique, develop a formula to define its limits of accuracy, and report on its clinical application. Methods: Using the positioning laser grid lines on the computed tomography scanner, a small metallic marker is placed on the scalp at the intended biopsy site. The distance between the tumor and the inner table of the bone is measured. In the operating theater, the patient is positioned such that the tip and the bridge of the nose are aligned in a horizontal position. The patient's two eyebrows or the orbital canthi are aligned in a vertical line. Simultaneously, the posterior borders of the two pinnae are aligned vertically. Gravity is used to guide the biopsy needle through the marked burr hole into the target. Seven patients had biopsies. One was for targeting the craniopharyngioma cyst to place an Ommaya catheter. The fraction of error or error fraction (EF), was developed for verification of its limits of accuracy. Results: All the biopsies were diagnostic and the Ommaya catheter was correctly sited. The EFs at alpha = 5 degrees were all predictive of the limits of accuracy of this technique. Conclusion: This is the first reported gravity-guided stereotactic brain surgery. The outcome in all the eight cases showed that it was within the limits of its accuracy. EF can be calculated to ensure accuracy. This technique is helpful if a commercial stereotactic system is not available. PMID- 30283516 TI - Magnetic Resonance Imaging and Neuropsychological Correlates of Subcortical Vascular Dementia. AB - : Common understanding of dementia is mostly based on the Alzheimer's disease model. However, in subcortical vascular dementia (SVaD), several other cognitive and behavioral dysfunctions predominate over what is commonly noticed in Alzheimer's disease. There are inconsistencies in literature regarding the profile of cognitive impairments in vascular dementia. Objective: In the current study, different cognitive functions pertaining to different lobes of the brain along with neuropsychiatric symptoms we explored in a holistic manner. Materials and Methods: A sample of 12 patients diagnosed with SVaD without any comorbidity were recruited for the study. All the patients underwent magnetic resonance imaging (MRI) scanning and different standardized neuropsychological tests were administered. Results: Patients reported various neuropsychiatric symptoms with varied severity, mostly falling in moderate range, reflecting organic personality change. Most of the cognitive functions pertaining to different lobes of the brain were impaired with parietal lobe being intact mostly. Comparison of MRI findings and neuropsychological findings revealed that there is involvement of cortical functions with the impairment in subcortical structure. Conclusion: These findings emphasis need to look beyond clinical diagnosis and MRI findings for better rehabilitation of the patients by including cognitive dysfunction as well as emotional disturbances prominent in SVaD which might me quite distressing for caretakers. PMID- 30283517 TI - Prehospital Care in Traumatic Brain Injury: Factors Affecting Patient's Outcome. AB - Background: Traumatic brain injury (TBI) is the leading cause of deaths worldwide. The morbidity and mortality due to TBI are related to both primary as well as secondary insults. The patients who survive from the primary insults, some may still have long-term disabilities. Most of these outcomes are related to the high incidence of prehospital secondary brain insults. Knowledge of these variables and timely management of the disease at the prehospital level can significantly improve the outcome and decrease the mortality. Aims: The present study is aimed to evaluate the current status of prehospital care, prehospital factors, epidemiological characteristics, and outcome of TBI patients at a Level 1 trauma center. Material and Methods: It is a prospective observational study of 830 cases of TBI, done from November 15, 2015, to March 15, 2016, in the Department of Neurosurgery, Institute of Traumatology, SMS Medical College, Jaipur, Rajasthan, India. Results: Analysis of data revealed that the incidence of TBI in males is four times higher than females. Most patients are in the age group of 21-30 years (30.24%) followed by 31-40 years (18.55%). Road traffic injury (69.52%) is the most common mode of injury in the age group of 21-30 years followed by injury due to fall (22.77%) which mostly affects the age group of 0 10 years (72.64%) and 61-70 years (38.6%). Analysis of different factors revealed that age is significantly correlated with the outcome having P = 0.016. Glasgow Coma Scale, saturation of peripheral oxygen, systolic blood pressure at admission are also significantly correlated with the outcome having P < 0.001, P < 0.001, and P < 0.001, respectively. Conclusion: It is evident from the study that the factors which affect the outcome of a TBI are influenced by prehospital care, and thus prehospital management of the TBIs can definitely improve the outcomes. PMID- 30283518 TI - Radical Resection of Craniopharyngioma: Discussions Based on Long-term Clinical Course and Histopathology of the Dissection Plane. AB - Objective: Craniopharyngioma is a benign tumor. However, sometimes, this tumor may recur repeatedly even after apparent total resection. This study investigated the requirements for ideal radical treatment, based on a discussion of the long term clinical course and pathological findings in surgical patients. Methods: We performed 81 surgical procedures for 67 patients with craniopharyngioma between February 1990 and December 2015. We classified patients into Groups I-III according to emphasis of surgery in chronological order, so we investigated the tumor recurrence rate and the necessity for postoperative hormonal replacement. Results: Multiple comparison of results from the three groups found significant differences in recurrence rate between Groups I and II (P = 0.0111) and Groups I and III (P = 0.0056). Although there were no differences in recurrence rate between Groups II and III, mortality rate of Group III was lower than that of Group II. No significant difference was seen between any group in terms of hormonal replacement. Conclusions: These results strongly suggest that the radical resection used to treat patients in Group III should be given priority as the procedure for removing craniopharyngioma. PMID- 30283519 TI - Efficacy of Amantadine in Improving Cognitive Dysfunction in Adults with Severe Traumatic Brain Injury in Indian Population: A Pilot Study. AB - Background: Severe traumatic brain injury (TBI) is associated with disabling cognitive impairment. Currently available options to improve the cognitive function have been futile. However, recently, commonly used medicine for Parkinson's disease, amantadine, has been shown to assist in the improvement of cognitive function. Methodology: We conducted a single institution-based observational study in adult Indian population. Fifty consecutive patients with documented static or declining cognitive function at 2 months of severe TBI fulfilling the inclusion/exclusion criteria received amantadine 200 mg/day (100 mg twice a day) orally or through enteral feeding tube for the duration of 4 weeks. The functional assessment done with Full Outline of Unresponsiveness (FOUR) score, Disability Rating Scale (DRS), and Glasgow Outcome Scale (GOS) during 4 weeks of treatment and 2 weeks posttreatment was assessed. Results: The cognitive function improved progressively during the 4-week treatment interval as shown by significant improvement on FOUR score, DRS, and GOS. However, after discontinuation of the drug, the speed of recovery slowed down significantly, but the achieved recovery was not lost. Out of fifty, eight patients had convulsions as an adverse effect of amantadine, of which five patients required discontinuation of the drug with treatment for convulsions. Conclusions: This study indicates the safety and efficacy of amantadine in partial reversal of cognitive dysfunction in adults with severe TBI in adult Indian population. PMID- 30283520 TI - Far-lateral Transcondylar Approach to Anterior Foramen Magnum Lesions - Our Experience. AB - Background: Initial surgical management of the anterior foramen magnum lesions through the posterior approaches was fraught with unacceptable morbidity, mortality, and incomplete removal. The far-lateral approach provides excellent exposure and access to these lesions resulting in complete excision of these lesions with reduced frequency of unwanted complications. Materials and Methods: Eight patients with lesions anterior to the brainstem and upper cervical cord were surgically treated using the far-lateral transcondylar approach. Two of these patients had a meningioma while three patients had "white epidermoid." One patient had a vertebral artery (VA) aneurysm while another was a rare case of lower brainstem compression by the VA and the last was a clival chordoma. The technical aspects of this surgical procedure are briefly illustrated in this article. Results: Total excision was achieved in five neoplastic cases while subtotal excision was done in one case. The VA aneurysm was satisfactorily clipped while in the brainstem compression patient, microvascular decompression was done. The VA aneurysm patient developed postoperative lower cranial nerve palsies. There were no fresh postoperative deficits in any of the other patients. One patient had an unexplained sudden cardiorespiratory arrest 18 h after the surgery and succumbed. One patient had cerebrospinal fluid (CSF) otorrhea which was satisfactorily managed by intrathecal CSF drainage. Conclusion: The far lateral transcondylar approach provides excellent approach to lesions located anterior to the brainstem and upper cervical cord. Total excision of these benign lesions is safely possible through this approach. PMID- 30283522 TI - What do You Expect from Patients with Severe Head Trauma? AB - Background: Head trauma is one of the most common mortality and morbidity causes in adolescent. Numerous studies have been conducted on changes in laboratory results and mortality and morbidity prognostic factors; however, the obtained results have been varied and controversial. The aim of this study is to evaluate changes in laboratory findings and arterial blood gas (ABG) analyses test at admission and investigation of the relation between these changes with outcomes in patients with traumatic brain injury. Materials and Methods: In this study, laboratory and metabolic variables were compared in patients with severe brain trauma and normal subjects. Laboratory and metabolic variables and ABG were measured on admission in patients with severe brain trauma and then compared with normal values. At last, the correlation between these variables with the prognosis in the patients was studied. Results: Of 93 studied patients, 82 were male and 11 were female with the mean age of 30.54 years. Among the studied variables, prothrombin time (PT), partial thromboplastin time, international normalized ratio (INR), creatinine (Cr), blood sugar, sodium (Na+), potassium, white blood cell, and blood urea nitrogen increased while hemoglobin and platelet decreased significantly. Regarding the ABG results, the difference in PaCO2, HCO3, and SO2 at values was significant; whereas there were no statistical significant difference between the discharged and expired patients. In contrast, PT, INR, Cr, and Na had significant difference comparing the discharged and expired patients. Conclusion: Laboratory variables do change in patients with severe brain trauma; these changes are influential on patient prognosis, especially in case of PT, INR, Cr, and Na. PMID- 30283521 TI - Riluzole Can Improve Sensory and Motor Function in Patients with Acute Spinal Cord Injury. AB - Background: Spinal cord injury (SCI) causes sensory, motor function and consists of a large proportion of patients that referred to trauma centers. Riluzole blocks the sodium channels and has possible supportive effects on the central nervous system. The aim of this study was to investigate the effect of riluzole on sensory and motor improvement and pain level in patients with acute SCI. Materials and Methods: In this clinical trial, sixty patients with acute SCI with A to C Frankel grade selected and randomly divided into two groups (each group included thirty patients). The two groups carefully matched in terms of age, sex, and Frankel class. Case group, in addition to conventional treatment, received riluzole and was evaluated after 6-week, 3-month, and 6-month periods in terms of sensory and motor status and compared with control group. Results: There were sixty patients divided into case and control groups. In the 6-week follow-up period and 3-month follow-up period, there was no significant difference between the two groups based on sensory and motor function (P = 0.053). In 6-month follow up period, the difference was significant in case group (P = 0.001). Conclusion: The compressions between two groups demonstrated a significant difference in sensory and motor improvement and reduce pain level in patients with SCI. PMID- 30283523 TI - Effect of Local N-acetyl-cysteine in the Prevention of Epidural Fibrosis in Rat Laminectomy Model. AB - Background: Epidural fibrosis is a major contributing factor to the onset of failed back syndrome. Many studies have attempted to prevent this physiological response. Interestingly, N-acetyl-cysteine (NAC) has been effective in some cases in the treatment of pulmonary fibrosis. Objective: The objective of this study was to determine whether local NAC is an effective way to prevent epidural fibrosis after laminectomy in rats. Materials and Methods: Twenty Wistar rats were used in this study. Animals were divided into two groups: NAC group and a control group. We performed two-level laminectomy (L4-L5) in these rats. Rats in the control group just had laminectomy, and in the other group, L4 and L5 laminectomy followed by local treatment with NAC. Four weeks later, the rats were killed, and the laminectomy level was subjected to histopathological examination to evaluate epidural fibrosis and fibroblast density. Results: Histopathological examination showed that after 4 weeks of surgery the NAC group had significantly less epidural fibrosis and fibroblasts compared with control group. Conclusion: Our findings indicate that NAC decreased spinal epidural fibrosis after laminectomy in rats. PMID- 30283524 TI - Aneurysmal Subarachnoid Hemorrhage: Geography has a Role. AB - Background: The incidence of aneurysmal subarachnoid hemorrhage (SAH) reported in the literature has been very variable. Many authors have proposed a geographical variation in incidence, but others have dismissed this as being due to insufficient pickup rate. In India also, these arguments abound. Our aim was to find out if geographical variations exist in the incidence of aneurysmal SAH and whether the incidence of aneurysmal SAH was truly less in India as compared to the literature. Materials and Methods: The data from 182 consecutive cases of SAH admitted to this institution between March 1999 and July 2003 were used for this study. Results: There were 84 females and 98 males in this study. More than half of the patients were hypertensive. Four-vessel angiogram was done in 113 patients, of whom sixty-nine were normal. Of the patients with hypertension, 92% had angiogram done and was normal in 65% of cases. Conclusions: This study from a large general hospital in South India shows that the incidence of aneurysmal rupture as a cause of SAH is much less in India and probably in the Indian subcontinent in comparison with the western literature thus demonstrating geographical variations in the incidence of aneurysmal SAH. It is concluded that aneurysms as a cause of SAH are still less in India and that we are not missing anything. This study is intended to help target scarce, expensive resources toward more common pathologies. PMID- 30283525 TI - Microsurgical Anatomy of Medial Temporal Lobe in North-West Indian Population: Cadaveric Brain Dissection. AB - Aim: The medial temporal lobe (MTL) is a highly complex neuroanatomical structure of tremendous neurosurgical importance. It is a common site for epilepsy, vascular lesions, and tumors. Owing to the critical location behind the sphenoid wing, it is more prone for traumatic contusion often with surgical implications. Hence, its microneurosurgical anatomy needs to be evaluated in detail. Materials and Methods: Twelve formalin-fixed human cadaveric brains from North-west Indian population were dissected under neurosurgical microscope and various dimensions of the MTL and their distance from important neurovascular structures were measured. Results: The MTL consists of important neural structures such as parahippocampal gyrus, uncus, hippocampus, temporal horn, and choroidal fissure. The average distance of tentorium from the uncus was 1.96 mm. The temporal horn and the inferior choroidal point were located from the anterior temporal pole at 22.9 mm and 30.9 mm, respectively. Important vessels that are intimately related to the MTL were anterior choroidal artery (AchA), posterior communicating artery, the P1 segment of posterior cerebral artery, and the M1 segment of middle cerebral artery. Conclusion: Complex anatomic and cytostructural organization makes the MTL unique. In this study, along with the descriptive anatomy, morphometric measurements of various structures were performed. The uncus and its relation to other neurovascular structures is well described in literature, but its exact distance from them as determined in this study is particularly helpful in guiding the surgeons while approaching in this area. Knowledge of the distance of the temporal horn from various surfaces is important while opening the temporal horn to avoid unnecessary damage to nearby structures. PMID- 30283526 TI - Pediatric Extradural Hematoma: Clinical Assessment Using King's Outcome Scale for Childhood Head Injury. AB - Introduction: Epidural hematoma (EDH) is a traumatic accumulation of blood between the inner table of the skull and the stripped off dural membrane and predominantly consists of venous blood in infants. The study aims to assess the outcome of pediatric EDH using King's Outcome Scale for Childhood Head Injury (KOSCHI). Materials and Methods: A total of 72 patients' files were reviewed retrospectively with a diagnosis of EDH from January 2012 to December 2014. Predesigned proforma was filled using data from patient records. In addition, KOSCHI was calculated using recent telephone interviews. Results: Among 72 patients, 65.3% were male and 34.7% were female. Overall, road traffic accident was the most common cause (52.8%) followed by fall, assault, and sports injury. The most common symptom was more than two episodes of vomiting which was present in 51.4% of patients followed by loss of consciousness in 37.5%, ENT bleed in 33.3%, headache in 16.7%, and fits in 11.1% of patients. The median follow-up of our patients was 19 (6-40) months. Most of our patients made good recovery with 76.4% of our patients scoring 5b on KOSCHI. Conclusion: EDH is not uncommon among children with head injury. It should be suspected in every child with posttraumatic skull fracture or scalp hematoma. Prompt surgical intervention can give good long-term outcome. PMID- 30283527 TI - Serum Magnesium as a Marker of Neurological Outcome in Severe Traumatic Brain Injury Patients. AB - : Hypomagnesemia is postulated as one of the important determinants of outcome following traumatic brain injury (TBI) through its effect on secondary injuries to neurons. Aims and Objective: The aim of this study was to determine the relationship between serum magnesium level and neurological outcome in patients admitted with severe head injury. Materials and Methods: In this prospective study, patients admitted with severe TBI were recruited and dichotomized into low serum magnesium group and normal serum magnesium group based on the initial serum magnesium level. Data were collected regarding age, sex, and Glasgow Coma Scale at admission. Neurological outcome of the patients in these groups was assessed using Glasgow Outcome Scale at 6 months. Results: Seventy-two patients (male = 50, female = 22) with a mean (+/-standard deviation) age of 42.5 (+/-12.7) years were studied. Forty-two (58%) patients had low serum magnesium level (<1.3 mEq/L) at admissions. At 6-month follow-up, 81% of patients with poor neurological outcome had low serum magnesium as compared to 19% of patients with good outcome (P = 0.01). Hypomagnesemia was associated with poor neurological outcome (odds ratio = 2.1, P = 0.04, 95% confidence interval = 1.0-8.8) on regression analysis. Conclusion: Hypomagnesemia appears to be an independent prognostic marker in patients with severe TBI. PMID- 30283528 TI - Morphometric Study of Basilar Artery in the Eastern Indian Population. AB - Introduction: The basilar artery (BA) is formed by the fusion of right and left vertebral arteries and divides to form right and left posterior cerebral arteries. This study was done to provide a baseline database regarding length, mid-length diameter, level of origin, and level of termination of BA. Materials and Methods: Thirty-eight formalin-fixed brains were obtained from cadavers dissected for undergraduate studies. The external length and the average external diameter of BA were measured by a digital Vernier caliper. Variation in origin and termination of BA was noted using magnifying glass. Results: The length and diameter of the BA were 25.58 +/- 3.57 mm and 3.05 +/- 0.41 mm, respectively. The origin and termination of BA was normal in most cases. In two cases, the origin was above the pontomedullary junction, and in one case, it was below. In two cases, the termination was above the pontomesencephalic junction, and in one case, it was below. Conclusion: There was no gender predisposition in length and diameter of the basilar artery. The baseline data established in this study regarding length, diameter, level of origin and level of termination of basilar artery will help neurosurgeons and interventional radiologists to diagnose as well as plan and execute various vascular procedures such as shunting for the treatment of aneurysms and stenosis in the blood vessels of the posterior cranial fossa. PMID- 30283529 TI - Osteoporosis Presenting as Low Backache: An Entity not Uncommon to be Missed. AB - Introduction: Low backache (LBA) is highly prevalent in osteoporotic patients and affects their quality of life. Overall, osteoporosis incidence is greater in females than in males, and osteoporotic fractures typically occur with only modest or moderate trauma. Aims and Objectives: To evaluate osteoporosis as a cause of LBA in patients attending a neurosurgical outpatient department and to study various risk factors associated with it. Materials and Methods: The study entitled "Osteoporosis presenting as LBA: An entity not uncommon to be missed" was a 2-year hospital-based study conducted from August 2014 to July 2016 in a prospective manner and included 100 patients of osteoporosis with LBA. Analysis of records included their chief complaints, signs and symptoms, diagnostic investigations performed, treatment modalities they underwent, and further recommended management carried on them. Results: Out of total 100 patients evaluated, 33 (33%) were male and 67 (67%) were female; the age of patients was in the range of 35-70 years (mean 56.54 +/- 91). The number of patients with a significant medical or surgical history was 31 (31%). The history of drug intake such as thyroxine, steroids, and antiepileptics was present in a total of 11 patients out of which 10 were female and one was male. Regarding lifestyle characteristics of studied patients, a total number of 72 (72%) were having sedentary habits with 15 (45.5%) males and 57 (85.1) females, the total number of moderate workers was 19 (27.3) males and 10 (14.9%) females, and heavy workers were 9 (9%) with 9 (27.3) males and 0 (0%) female. Conclusion: LBA is highly prevalent in osteoporotic patients especially in women. The incidence of osteoporosis and LBA increased with low body mass index, increasing age, and duration of menopause. The various risk factors for osteoporosis include smoking, history of medical diseases such as diabetes mellitus, history of hysterectomy, and history of antiepileptic, thyroxine, and steroid intake. PMID- 30283530 TI - The Benefits of Decision Tree to Predict Survival in Patients with Glioblastoma Multiforme with the Use of Clinical and Imaging Features. AB - Background: Machine learning is a type of artificial intelligence which aims to improve machine with the ability of extracting knowledge from the environment. Glioblastoma multiforme (GBM) is one of the most common and aggressive primary malignant brain tumors in adults. Due to a low rate of survival in patients with these tumors, machine learning can help physicians for better decision-making. The aim of this paper is to develop a machine learning model for predicting the survival rate of patients with GBM based on clinical features and magnetic resonance imaging (MRI). Materials and Methods: The present investigation is an observational study conducted to predict the survival rate in patients with GBM in 12 months. Fifty-five patients who were registered in five Iranian Hospitals (Tehran) during 2012-2014 were selected in this study. Results: This study used Cox and C5.0 decision tree models based on clinical features and combined them with MRI. Accuracy, sensitivity, and specification parameters used to evaluate the models. The result of Cox and C5.0 for clinical feature was <32.73%, 22.5%, 45.83%>, <72.73%, 67.74%, 79.19%>, respectively; also, the result of Cox and C5.0 for both features was <60%, 48.58%, 75%>, <90.91%, 96.77%, 88.33%>, respectively. Conclusion: Using C5.0 decision tree model in both survival models including clinical features, both the imaging features and the clinical features as the covariates, shows additional predictive values and better results. The tumor width and Karnofsky performance status scores were determined as the most important parameters in the survival prediction of these types of patients. PMID- 30283531 TI - Management of Postoperative Discitis: A Review of 31 Patients. AB - Background: The aim of the study was to retrospectively evaluate the outcome of medical management of postoperative discitis (POD). Materials and Methods: A total of 31 patients treated for POD were included in the study. Clinical, radiological, and laboratory data of all patients were collected and evaluated. All patients were treated initially with bed rest and antibiotic therapy after radiological diagnosis. Surgical management was undertaken after failure of 4 weeks of conservative management. All cases were followed clinically with laboratory and radiological investigations. Results: Five cases failed to respond to medical management and were treated surgically with debridement and transpedicular fixation. All patients showed clinical recovery till the last follow-up. Conclusion: Early diagnosis and proper management are the keys to successful outcome of postoperative spndylodiscitis. Surgical debridement and fusion are required when conservative treatment fails. PMID- 30283532 TI - Study of Incidence and Factors: Risk and Preventive, of Chronic Subdural Hematoma/hygroma in Clipped Patients of Unruptured Intracranial Aneurysms - An Institutional Experience. AB - Introduction: One of the underreported complications of clipping of unruptured aneurysm is chronic subdural hematoma/hygroma (CSDH). It can cause sudden deterioration and might need emergency evacuation. Recently, very few papers have studied its incidence and predisposing factors. We are reporting our institutional experience of it along with the study of its risk factors and possible pathogenesis. Methodology: Totally 91 postoperative patients of unruptured aneurysms were retrospectively analyzed. Totally 21 patients had CSDH who were operated. In rest seventy patients, there was no CSDH. Results: Male sex, old age, anticoagulant use, presence of pneumocephalus and dead space were significantly associated with occurrence of CSDH, whereas arachnoidoplasty significantly protected against it. There was no significant relation of CSDH with Gorei-san use. Conclusions: We recommend arachnoidoplasty should be carried out in all patients of clipping of unruptured aneurysm. Male patients or/and patients with dead space with pneumocephalus must be given extra attention like avoiding any dead space in postoperative period, doing arachnoidoplasty and regular follow up till 1st year. PMID- 30283534 TI - Favorable Outcome of Endovascular Treatment for Intracranial Aneurysms: A Single Center Study in Thailand. AB - Purpose: The purpose of this study is to collect the information on patients with intracranial aneurysm (IA) receiving endovascular management in Siriraj Hospital, Mahidol University, Thailand. Materials and Methods: We retrospectively reviewed data from patients with IA who underwent endovascular treatment from January 1997 through July 2013. We collected patients' demographic data including age, sex, clinical presentations, and aneurysmal profiles, as well as endovascular treatment technique, complications, angiographic results, and regrowth rate. Treatment results included success rate, clinical findings during follow-up, and regrowth rate. Results: We reviewed data from 497 patients with 636 aneurysms (female:male ratio, 1.9:1; age range, 15-90 years; mean age, 59.18 years) and 69% presented with rupture. One hundred and twenty patients with 127 aneurysms received endovascular treatment. The most common location for endovascular treatment was the posterior communicating artery (15.8%), and endovascular techniques were used most often for posterior circulation and paraclinoid aneurysms. The success rate was approximately 99.2% with a 16.5% regrowth rate and no rebleeding. Regrowth rate did not correlate with immediate postoperative angiographic findings. We encountered 23 complications (18.1%); most commonly, intra-procedural rupture (7/23). Good outcomes occurred in approximately 95.9% of the patients. Conclusions: The success rate for endovascular treatment was >90%. Regrowth rate and clinical outcomes were within standard limits. Posterior circulation and paraclinoid aneurysms were our main targets. We tended to use fewer devices and simpler techniques to secure ruptured IA; however, the regrowth rate was similar to that using device-assisted techniques in other studies. We found no significant factors affecting regrowth rate, including immediate posttreatment angiographic results. PMID- 30283533 TI - Morbidity Audit of 704 Traumatic Brain Injury Cases in a Dedicated South Indian Trauma Center. AB - Background: In the era of evidence-based health care, protocol of intervention in traumatic brain injury (TBI) cases help decide more easily and safely about patients and prevent unnecessary transfer of patients to other centers. Objectives: The objective of this study is to provide protocol-based intervention and evaluate the epidemiological, clinical characteristics of TBI cases. Methods: This prospective study was conducted on 704 patients who were suspected of TBI at the Department of Neurosurgery, Narayana Medical College and Hospital, followed by protocol-based intervention assessed and reassessed repeatedly. Results: Overall, TBI involved 569 (80.82%) adults in the productive age groups (21-60 years); among males 81.47%. Among males, highest (23.15%) cases were in the age group of 31-40 years while in females, majority (27.04%) was among 41-50 years. Road traffic accidents were the most common (54.12%) mechanism of injury followed by fall (21.31%) and two-wheelers (15.20%). More than half sustained mild TBI (51.42%) while 26.28% moderate TBI and 22.30% severe TBI; among males, severe TBI victims 102 (18.82%) were in the productive age group. Loss of consciousness was almost a universal and significant observation (95.45%); vomiting was next common finding (76.42%). Bleeding from the ear-nose-throat (ENT) region was more in males (33.58%) than females (20.75%). Glasgow coma scale was significantly related with loss of consciousness (91.08%), vomiting (63.06%), and ENT bleeding (44.59%) in severe, moderate, and mild injuries. Conclusion: A rational clinical acumen with judicious use of diagnostic protocol leads to better management of TBI without unnecessary imaging and thus reduce total health-care costs. PMID- 30283535 TI - Factors Affecting Functional Outcome after Decompressive Craniectomy Performed for Traumatic Brain Injury: A Retrospective, Cross-sectional Study. AB - Background: Factors affecting functional outcome after decompressive craniectomy (DC) performed for traumatic brain injury (TBI) remain poorly understood. Methods: We conducted a retrospective study of all patients who underwent primary DC for TBI at our hospital between 2010 and 2014. Multivariate regression analyses were used to determine the predictors of functional outcome and overall survival. Results: A total of 98 patients with severe (n = 81, 82.6%) or moderate (n = 17, 17.4%) TBI underwent primary DC and were included in this study. The 30 day and overall mortality rates were 15.3% and 25.5%, respectively. At a median follow-up of 90 (interquartile range (IQR): 38-180) days, median Karnofsky Performance Status (KPS) and Glasgow outcome scale-extended (GOSE) scores were 50 (IQR: 20-70) and 5 (IQR: 3-7), respectively. Young age and severe TBI were predictors of mortality. Glasgow coma scale (GCS) score on discharge was a strong predictor of KPS and GOSE scores. Conclusion: Primary DC afforded an acceptable functional outcome (GOSE score >=5) in 45.9% of patients. Young age and lower GCS at presentation were associated with worse survival. GCS score on discharge was a strong predictor of functional outcome. PMID- 30283536 TI - Prognosis of Hormonal Deficits in Empty Sella Syndrome Using Neuroimaging. AB - Aim: We have evaluated the anatomic measurements on sellar area of patients who were radiologically diagnosed with empty sella to determine the relation between the amount of pressure on the adenohypophysis and hormonal imbalances. Materials and Methods: Sixty-one cases were diagnosed with empty sella and had hormone tests and hypophysis magnetic resonance (MR). The cases were categorized into two groups - patients with hypophyseal hormone anomaly and patients without hormone anomaly. We have measured interclinoid distance, anteroposterior distance from the anterior diaphragm sella to the pituitary stalk, depth of the sella turcica, craniocaudal distance of the optic chiasm from the diaphragm sella, the heights of the right and left adenohypophysis, subcutaneous fat thickness measured orthogonal to the coronal suture and posteriorly at the level of C2-C3 for two groups on hypophysis and cranial MR imaging MRI. Results: Twenty-five hormone positive cases (40.9%) (hormone test were abnormal) and 36 hormone-negative cases (59.1%) (hormone tests were normal) were included in the study. The most common hormone abnormality was thyroid-stimulating hormone, T3 and T4 deficiency in 12 cases (48%) and increase in prolactin level in 7 cases (28%). Right adenohypophysis height was 1.54 +/- 0.840 mm for the 1st group, and 1.96 +/- 0.83 mm for the 2nd group. The left adenohypophysis height was 1.66 +/- 0.80 mm for the 1st group, and 1.94 +/- 0.94 mm for the 2nd group. It was found out that the thickness at right and left side in the hormone-positive group diminished significantly. Conclusion: Adenohypophysis height and distance between stalk and optic nerve were good determiner for hormone defect. PMID- 30283537 TI - Nonmissile Anterior Skull-Base Penetrating Brain Injury: Experience with 22 Patients. AB - Background: Nonmissile anterior skull-base penetrating brain injuries (NASBPBIs) have specific characteristic features that are different from missile injuries. Our study presents our experiences on the characteristic features as well as management of NASBPBI. Materials and Methods: We retrospectively reviewed 22 consecutive patients with NASBPBI managed at our institute during a 13-year period. The mechanism of injury, clinical investigations, and complications were analyzed, with more emphasis on diagnostic and treatment regimen. Results: The 22 cases included in our study comprise of 20 males and 2 females. Majority (72.7%) of the patients were adults with a mean age of 27.5 years. The mechanisms of injury often include accidental fall, either onto a small-diameter sharp object (10 cases) or while carrying such an object in the hand (4 cases). The other common mechanisms were stabbing, accident, or during an altercation (8 cases). Clinical manifestations included periorbital hematoma (10 cases, 45.5%) and cerebrospinal fluid rhinorrhea or orbitorrhea (4 cases, 18.2%) as well as signs of embedded foreign object (8 cases, 36.4%). We performed emergency craniotomy in 21 cases and skin debridement in one case. Postoperative complications were abscess (1 case), epilepsy (1 case), and traumatic carotid-cavernous fistula (1 case). Conclusion: Nonmissile injuries are generally on the rise and therefore deserve more attention. We observed that clinical outcomes were excellent in 14 (Glasgow Outcome Scale [GOS] score of 5) and good in the remaining 8 patients (GOS of 4) during 6-month-10-year (mean 4.6 years) follow-ups. PMID- 30283538 TI - The Effectiveness of Dural Venous Sinus Sacrifice as a Treatment of Aggressive Type Cranial Dural Arteriovenous Fistulas. AB - Objective: To evaluate the effectiveness of dural venous sinus sacrifice as a treatment of aggressive type cranial dural arteriovenous fistulas (dAVFs) in terms of both clinical outcome and angiographic outcome. Materials and Methods: One hundred and twenty-eight patients with 163 aggressive type cranial dAVFs who were treated with dural sinus sacrifice were retrospectively reviewed. Clinical and angiographic outcomes were analyzed. Procedural complications were also recorded. Only 103 patients (80.5%) who had been following up for at least 90 days were analyzed for clinical outcome. Results: There were 53 males and 75 females with age ranging from 20 years to 93 years (mean age 55.44 years). The overall angiographic cure rate of dural venous sinus sacrifice as a part of the treatment of aggressive dAVFs was 81.6%. Considering clinical outcome (average duration of follow-up was 2 years and 6 months), 75 patients (72.8%) had clinical improvement and 21 (20.4%) were clinically stable. Worsening of the presenting symptoms was observed in 7 patients (6.8%). Procedural complications were found in 5 patients (3.9%). Conclusion: Dural venous sinus sacrifice is a safe and effective treatment strategy with high angiographic cure rate, good clinical outcome, and low incidence of procedural-related complication. PMID- 30283539 TI - Stab Wounds to the Head; Case Series, Review of Literature, and Proposed Management Algorithm. AB - Background and Objectives: Stabbing the head is a rare event. It may occur following an assault or self-inflicted injury. We intend to report our experience with four such cases and review narratively the relevant literature. A treatment algorithm will be delivered. Materials and Methods: We have reviewed four of our cases; three were stabbed to the orbit and one to the head. Results: Enucleation was performed in one case. Vision could be preserved in the other two and brain abscess developed in the other cases due to a retained piece of knife. We made a comparison between our cases and those limited reports in the literature to reach an algorithm. Conclusion: The temporal region and the orbit are the targets mostly attacked in the craniofacial stabs. Since knives have a sharp and thin edge, they may break when penetrating the skull. The damage to the brain tissue and the retained piece of knife may be missed easily by overlooking the small injury to the scalp. The suggested algorithm would be a contrast-enhanced computed tomography scan of the skull and brain and a kind of brain vascular study are necessary, considering the location of the knife in the skull and brain passing the area with crowded vasculature. The best treatment protocol is surgery accompanied by antibiotic therapy. PMID- 30283540 TI - Hemilaminectomy for Spinal Cord Intradural Tumors: An Institutional Experience. AB - Introduction: Laminectomy is the workhorse of spinal cord tumor surgery. This procedure is not without the debilitating sequelae of postoperative pain and delayed kyphosis. Hemilaminectomy is an alternate option to laminectomy which offers the advantage of preserving the posterior supporting structures of the spine on the contralateral side. In this study, we analyze the outcome of hemilaminectomy clinically with improvement in pain scores and Nurick's grade as well as radiologically by assessing for the development of delayed kyphosis. We also discuss the technique and operative nuances of hemilaminectomy in intradural extramedullary tumors of the spinal cord. Materials and Methods: All patients with intradural spinal cord tumors were included in the study. All patients underwent unilateral hemilaminectomy (UHL) depending on the laterality of the tumor on the preoperative magnetic resonance imaging. Preoperative neurologic status was assessed with Nurick's grade for tumors involving the cervicothoracic region tumors, and visual analog scale scores were recorded for tumors of Thoracic, Lumbar and Lumbosacral regions. The postoperative outcomes were assessed by improvement in respective scales on follow-up. The occurrence of delayed spinal deformity was assessed by follow-up X-rays. Any complications whether intraoperative or postoperative were recorded. Results: There were a total of 34 cases of intradural extramedullary tumors in this study. Patient population consisted of 11 males and 23 females. Total excision was achieved in 31 patients. In three patients, we were unable to achieve complete removal through UHL. In these patients the procedure was converted to total laminectomy. They were excluded from analysis. The distribution of the tumors was in cervical, cervicothoracic, thoracic, lumbar, and lumbosacral region. All patients presented with pain or varying degrees or neurologic deficits. Sixteen patients underwent UHL from the right side, while 18 from the left. There were no intraoperative complications. The neurological status and pain scores of all patients improved postoperatively at 3 and 6 months of follow-up. There was no radiological evidence of kyphosis of the involved segment. Conclusion: With a small learning curve, UHL is a good corridor for the removal of intradural extramedullary spinal cord tumors. This approach offers the advantage of less postoperative pain and no postoperative deformity. PMID- 30283541 TI - Effect of Mannitol Irrigation on Brain Edema in a Live Rat Model. AB - Background: Mannitol has been used intravenously for decreasing cerebral edema since decades. The study was performed to evaluate the effect of its irrigation on edema in live rats. Edema was induced by artificial brain injury. We hereby present our results on the same using live rats and confirm its beneficial effect on reducing edema when used as irrigation. Aims: The aim of this study is to evaluate the effect of mannitol irrigation in reducing cerebral edema in rat brain after induction of artificial trauma and to compare the results with standard normal saline irrigation using randomized controlled study. Settings and Design: This study was a prospective randomized controlled trial. Materials and Methods: A total of 20 fully grown Albino Wistar rats were subjected to artificial trauma after a burr hole and divided randomly into two groups of ten rats each. One group was subjected to mannitol irrigation after durotomy and the other was subjected to normal saline. Tissue biopsy was sent at the end of 1 h to check for the status of edema and was classified into three grades. Statistical Analysis Used: Comparison of proportions test. Results: Mannitol irrigation produced a statistically significant difference (P = 0.022) in the grade of edema at the end of 1 h as compared to normal saline. Conclusions: Mannitol irrigation can be used during neurosurgical procedures instead of normal saline to reduce postoperative brain edema. PMID- 30283542 TI - Burr Holes Revascularization in Three Pediatric Cases of Moyamoya Syndrome: Easy Choice or Insidious Trap? Case Series and Review. AB - Introduction: Moyamoya disease is a steno-occlusive cerebrovascular disease of unknown etiology involving the terminal portion of the internal carotid artery and the proximal portions of the anterior and middle cerebral arteries with associated collateral vascular network. When the vascular pattern is associated with a particular condition (e.g., Type 1 neurofibromatosis, Down syndrome), it is defined as moyamoya syndrome (MMS) (or quasi-moyamoya). Among different indirect bypass techniques used to prevent ischemic injury by increasing collateral blood flow to hypoperfused areas of the cortex, multiple burr holes technique is an easy and diffuse indirect revascularization approach in the treatment of moyamoya. Discussion: While the effectiveness in patients with moyamoya disease was demonstrated, its role in MMS remains uncertain. In this study, we describe surgical and diagnostic implications in three pediatric cases of moyamoya sydrome unsuccessfully treated with multiple cranial burr hole technique. A critical review of the literature about the use of the surgical indirect revascularization techniques in pediatric patients was also reported. PMID- 30283544 TI - Technique of Posterior Clinoidectomy and Its Applications. AB - An understanding of the microsurgical anatomy of posterior clinoid process (PCP) is extremely important to where the removal of PCP is required to access the interpeduncular and prepontine cisterns and upper basilar artery region to manage the aneurysms located in this region. In the present article, we describe our experience with a technique that is safe and provides ample space to look into these regions. The key to safe drilling is that the drilling of the posterior clinoid needs to be performed in a "touch and back" manner (rather than clockwise or counterclockwise motion) to break the cortex. PMID- 30283543 TI - Congenital Absence of Unilateral Internal Carotid Artery with an Intracerebral Aneurysm. AB - The absence of the internal carotid artery (ICA) is a rare congenital anomaly. Diagnosis of this entity is important because of its association with the cerebral aneurysm and also indicated during planned carotid or transsphenoidal surgery in thromboembolic disease and in the surveillance and detection of associated cerebral aneurysms. We report a case of congenital absence of unilateral ICA with associated cerebral aneurysm of the anterior cerebral artery. PMID- 30283545 TI - Temporary Worsening of Perianeurysmal Edema Following Clipping of a Partially Thrombosed Giant Pericallosal Artery Aneurysm. AB - We present a case of a partially thrombosed giant aneurysm of the pericallosal artery that experienced a temporary worsening of perianeurysmal edema after clipping. A 66-year-old man presented with progressive weakness of the right leg. Imaging studies revealed a partially thrombosed giant aneurysm at the bifurcation of the left pericallosal artery with concomitant perianeurysmal edema. The aneurysm was thought responsible for the symptoms of the patient, and he agreed to undergo clipping surgery. The aneurysmal neck was clipped using two long aneurysm clips without dissecting the aneurysmal dome. The patient woke up from anesthesia with the right-sided hemiparesis, which progressed to hemiplegia by 12 h after surgery. Brain computed tomography revealed worsening of the perianeurysmal edema. Fortunately, his symptoms resolved completely by 2 weeks after surgery with conservative management. Perianeurysmal edema is frequently observed in patients with partially thrombosed giant aneurysms. Although worsening of perianeurysmal edema is a relatively common complication of endovascular procedures, its occurrence after clipping has rarely been reported. The worsening may have been induced by release of inflammatory cytokines from aneurysm wall, which was rendered ischemic due to obliteration of the vasa vasorum by the clips. Perianeurysmal edema may develop or worsen after clipping of a partially thrombosed giant aneurysm if the interface between the aneurysm and surrounding brain is not fully dissected. PMID- 30283546 TI - Trans-Sellar Trans-Sphenoidal Herniation of Third Ventricle with Cleft Palate and Microophthalmia: Report of a Case and Review of Literature. AB - Trans -sellar trans-sphenoidal encephalocele is an extremely rare entity. We present the case of an 18-month old boy who presented with a trans-sellar, trans sphenoidal encephalocele associated with cleft lip, cleft palate and microphthalmia. This patient was treated successfully by a trans-cranial extra dural route. In this paper, we discuss the clinico-radiological findings as well as various surgical options in managing these rare lesions and briefly review the literature. PMID- 30283547 TI - Hemifacial Spasm Caused by a Vein: A Case Report. AB - Hemifacial spasm (HFS) caused by a venous offender is rare, and its clinical course and optimal surgical strategy are unclear. A case of 57-year-old male who had an HFS caused by a venous offender is described in this report. Frontalis, orbicularis oculi, orbicularis oris, and mentalis muscles were involved while his platysma muscle showed no spasm. He was treated successfully with microvascular decompression using Teflon felt and 12 months outcome was excellent without any complications. Lateral spread response was not observed in the facial electromyography during the whole operation. Adequate visualization of the facial nerve root exit zone and meticulous exploration for offenders are necessary to avoid surgical failure and reoperation. PMID- 30283548 TI - Occipital Interhemispheric Approach for Surgical Removal of the Middle Third Falx Meningioma: Two Case Reports. AB - Obtaining adequate working space is difficult for complete and safe resection of meningioma located in the middle third of the falx, because of the risk of damage to the bridging veins that flow into the superior sagittal sinus and the location near the eloquent area. Consequently, surgical resection of the meningioma in the middle third of the falx tends to result in neurological disorders caused by retraction of the brain and injury of the bridging vein. Two patients underwent tumor removal of the falx meningiomas located in the middle third of the falx through the occipital interhemispheric approach (OIA) in the lateral semiprone position with the affected side down. Tumor resection was achieved safely and less invasively. Both patients suffered numbness and motor weakness, but these neurological dysfunctions improved and clinical courses were uneventful. Postoperative computed tomography showed neither brain swelling nor contusion in both cases. The OIA can remove tumor in the middle third of the falx, because the approach avoids the bridging veins, and provides working space without excessive mechanical cerebral retraction. PMID- 30283549 TI - Scedosporium apiospermum: An Emerging Fatal Cause of Fungal Abscess and Ventriculitis after Near-drowning. AB - Herein, we describe a fatal case of central nervous system (CNS) pseudallescheriasis following near-drowning. A 13-year-old boy, who had been successfully resuscitated after near-drowning, presented with a transient episode of mental confusion during a hospital stay after recovering from severe aspiration pneumonia and respiratory failure. A magnetic resonance imaging (MRI) scan of the brain showed a small brain abscess in the left basal ganglia and ventriculitis in the left lateral ventricle. The brain abscess and ventriculitis did not respond to 4 weeks of antibiotic treatment and appeared even worse on a follow-up MRI. A diagnosis of CNS pseudallescheriasis was only possible with invasive stereotactic biopsy and aspiration of the abscess that showed the presence of hyphae and Scedosporium apiospermum. CNS pseudallescheriasis did not respond to multiple combinations of antifungal agents, including amphotericin B, isoconazole, itraconazole, and voriconazole. Two ventricular drainages and insertion of Ommaya reservoirs with intraventricular injection of voriconazole were insufficient to halt the infection. The patient passed away from sudden septic shock 2 months after identification of the brain abscess and ventriculitis. The patient's diagnosis was delayed because multiple examinations of the cerebrospinal fluid did not show positive cultures and could only be obtained from the aspirates of stereotactic biopsy. Physicians should be aware of CNS pseudallescheriasis associated with near-drowning because of the difficulty of diagnosis and the high mortality rate (70%) owing to poor responses to currently available antifungal agents. PMID- 30283550 TI - Oyster Calcification of Infected Bone Flap: A Rare Complication. AB - An extremely rare case of chronic epidural empyema after cranioplasty is presented. It derives its extreme rareness from its association with calcification. This patient when presented to our department had a complaint of swelling with on and off discharging sinus for 2 months adjacent to old incision scar mark. The patient had a history of decompressive craniectomy and evacuation of acute subdural hematoma, in some other institution, 8 years back. Following that, the patient underwent cranioplasty with the exteriorized and preserved bone flap. In the meantime, he was asymptomatic. It is a unique interesting case of chronic epidural empyema with calcified walls after 8 years of long duration following cranioplasty. PMID- 30283551 TI - Primary Giant Cerebral Hydatid Cyst in an 8-year-old Girl. AB - Echinococcosis, also called hydatid disease, is a parasitic disease that passes from animals to humans. Literature reports suggest very rare cases of cerebral hydatid cysts. Brain involvement with hydatid disease occurs in 1%-2% of all Echinococcus infections. In this report, we aim to emphasize the presentation of such an isolated primary cerebral hydatid cyst, discuss its radiological features, Emergency department management, inpatient medical management, referral to neurosurgery, consequent operative procedures, postoperative care, and outcome. PMID- 30283552 TI - Pyothorax-associated Angiosarcoma Metastasized to the Brain with Multiple and Progressively Expanding Hematomas: Case Report and Literature Review. AB - The brain metastasis of angiosarcoma is very rare, and little is known about its clinical features or therapeutic strategy. A 74-year-old male was hospitalized for disturbance of consciousness. Radiological examination revealed multiple cerebral hematomas. Gadolinium contrast-enhanced magnetic resonance imaging showed no significant enhancement at any of the lesions. To detect a suspected metastatic brain tumor or abscess, a full-body scan was performed but revealed only a poorly enhanced mass in the removal cavity caused by thoracoplasty in the left upper chest. After admission, a cascade of expansion of those hematomas occurred in the right frontal, left parietal, and right temporal lobes, and each lesion thus had to be sequentially removed by craniotomies. The pathological diagnosis of the right frontal lesion was an abscess with hematoma. However, a malignant vascular tumor was highly suspected because of many CD31(+)/Ki-67(+) cells in the left parietal lesion. A mass in the scar caused by thoracoplasty was suspected to be the primary lesion, and brain metastasis of angiosarcoma was finally diagnosed. Whole-brain irradiation and systemic paclitaxel administration were performed, and a complete response for the brain lesions was obtained for 22 months; the patient then died of an intratracheal hemorrhage. This case represents the first report of multiple brain metastases from pyothorax associated angiosarcoma accompanied by sequentially and gradually expanding hematomas, as well as the first case with the control of metastatic brain lesions for over 1 year after the onset of neurological symptoms. Control of the lesions could be achieved by their total removal with complete hemostasis, as well as additional radio- and chemotherapy. PMID- 30283553 TI - Spontaneous Transformation of Vestibular Schwannoma into Malignant Peripheral Nerve Sheath Tumor. AB - Although radiosurgery-induced transformation of vestibular schwannoma (VS) into malignant peripheral nerve sheath tumor (MPNST) is being widely discussed, little attention is paid to the spontaneous transition of these tumors. Although the pathogenesis of this phenomenon remains uncertain, growing number of reported cases might call to notice them. We present a case of a 29-year-old woman who suffered right-sided hearing loss which remained untreated for 4.5 years. Magnetic resonance imaging revealed a right cerebellopontine tumor and the patient underwent tumor removal through retrosigmoid approach. Pathologically, the tumor was benign acoustic schwannoma with increased Ki-67 8%-10%. The tumor relapsed only 6 months later and was removed again-this time it was malignant peripheral nerve sheath tumor MPNST. The patient was treated with stereotactic radiotherapy, but despite that tumor growth was observed again and she underwent the third operation. Later on, tumor progression was noted with multiple intraaxial metastases and patient died 17 months after the diagnosis of MPNST had been confirmed. This is a seventh documented case of spontaneous transformation of VS into MPNST, which is clinically important for recording. PMID- 30283554 TI - A Rare Case Report of Multiple Intracranial Aneurysms with Factor VII Deficiency. AB - Pathogenesis of intracranial aneurysms is multi-factorial. Origin of aneurysm may be acquired or genetic, and there may be more than one aneurysm simultaneously, or there may be the formation of a new aneurysm after treatment of previous one. Collagen vascular disorders, neurofibromatosis, polycystic kidney disease, and so many other disorders are associated with multiple intracranial aneurysms. As Factor VII deficiency is also genetic in origin, there might be a correlation between deficiency of the same with multiple intracranial aneurysms. Only one such case is reported in the literature and we are reporting such a rare case having a similar association. PMID- 30283555 TI - Rupture of Persistent Primitive Trigeminal Artery-basilar Artery Aneurysm Managed with Stent-assisted Coiling. AB - Persistent primitive trigeminal artery (PPTA), a fetal carotid-basilar anastomosis, is the most common embryological vascular remnant persisting into adult age. However, reported cases associated with cerebral aneurysms are rare. A 33-year-old female presented with an extremely rare PPTA-basilar artery (PPTA-BA) aneurysm manifesting as subarachnoid hemorrhage. Computed tomography revealed subarachnoid bleeding in the prepontine cistern, and cerebral angiography disclosed a PPTA-BA aneurysm. The aneurysm was managed with stent-assisted coiling technique to achieve complete obliteration. The patient was discharged without neurological deficits 2 weeks later. At 6 months follow-up, the patient is doing well and has returned to her previous daily activities. PPTA-BA aneurysms usually present with cranial nerve palsy and sometimes with carotid cavernous fistulae if they rupture. Their deep seating favors interventional management as a first option and this case illustrates the efficacy and safety of endovascular treatment. This case adds to the evidence that endovascular techniques are a safe and effective tool in managing aneurysms of the primitive trigeminal artery. Even in cases where the anastomosis itself is not preserved, the patient can be managed satisfactorily, provided that the patency of the basilar and the carotid artery are kept, like in our patient. PMID- 30283556 TI - Congenital Skull Anomaly with Multiple Brain Stones and Symptomatic Meningioma of Medial Sphenoid Wing. AB - Intracranial calcifications are not uncommon and are mostly seen with intracerebral hematomas, tuberculomas, and brain tumors. These lesions may be intra- or extra-axial and occasionally pose challenge in the diagnosis. We report a case of multiple intracranial extra-axial calcifications with congenital skull anomaly and multiple meningiomas. Authors could not find similar case reported in the literature and present their findings and discuss relevant literature. PMID- 30283557 TI - Malignant Conversion to Glioblastoma in Neurofibromatosis Type I-associated Pleomorphic Xanthoastrocytoma: Unknown Predictors of Favorable Outcome. AB - Pleomorphic xanthoastrocytoma (PXA) is a benign glial tumor, the association of which with neurofibromatosis type I (NF-1) has been often reported in the literature. Although malignant conversion to glioblastoma may be seen in 5%-10% of PXA, the same has been reported only once in the presence of NF-1. We report, so far known to be only the second such case all over. A 25-year-old male, a known case of NF-1, underwent frontal craniotomy for a superficially located right frontal lesion, histology of which suggested PXA. Two years later, the lesion recurred and the subsequent surgery revealed malignant conversion to glioblastoma. After adjuvant radiotherapy, the patient now continues to do well and is free of disease after another 3 years of follow-up. We believe that if low levels of neurofibromin are seen in such cases with malignant conversion, subsequently increased neurofibromin levels may be responsible for better overall survival in these patients. PMID- 30283558 TI - Multiple Extraneural Metastases of Anaplastic Oligodendroglioma. AB - Oligodendrogliomas (ODGs) is a diffuse glial tumor that constitutes 4.2% of all brain tumors. Extraneural metastases, sometimes seen in glioblastoma multiforme, are extremely rare in ODG. In this report, we present a 63-year-old male patient who was diagnosed with Grade 3 ODG and had an intracranial mass resected in our clinic 4 years ago. The subject now presented with low back pain and was found to have widespread metastases. The prolongation of patient survival by current treatment regimens has revealed a growing number of ODG patients with metastases. We believe that back pain complaints in patients with ODG should be viewed as an indicator of metastasis. PMID- 30283559 TI - Foramen Magnum Chordoid Meningioma in a 22-Year-old Female. AB - Chordoid meningioma is a rare variety of meningioma (0.5%-1%) with high rate of recurrence. They are grouped in WHO Grade II tumors. They are mainly distributed in the supratentorial location. There has been a single report of foramen magnum chordoid meningioma in a 3-year, 6-month-old child. Our patient, a 22-year-old female, admitted with progressive spastic quadriparesis with bowel and bladder involvement. She was operated with tumor resection done; postoperatively, patient showed dramatic improvement in the motor power as well as bowel and bladder function. Histopathology was suggestive of chordoid meningioma. She received 54 Gy of radiotherapy. She is doing well with no neurological deficits and no recurrence at 2-year follow-up. PMID- 30283560 TI - Impar Ganglion Block with Combination of Neurolysis Drugs and Radiofrequency Thermocoagulation for Perineal Pain. AB - Since it was first introduced, a variety of modification techniques to block the impar ganglion appear such as transsacrococcygeal ligament technique, sacrococcygeal transdiscal approach, paramedian approach, and a two-needle technique using fluoroscopy or computed tomography scan. For therapeutic purposes, a combination of steroid and local anesthetic, neurolysis agents such as alcohol, phenol, cryolesioning, and heat lesioning using radiofrequency thermocoagulation could be used. Here, we reported a successful outcome in treating chronic perineal pain in a 65-year-old patient using combination of neurolysis agent which was alcohol 96% and radiofrequency thermocoagulation. PMID- 30283561 TI - Major Depression and Obsessive-compulsive Disorder Treated with Deep Brain Stimulation of Bilateral Nucleus Accumbens: The First Case of Turkey. AB - Deep brain stimulation (DBS) is a new alternative treatment for treatment resistant major depression (MD) and obsessive-compulsive disorder (OCD). Various DBS targets were defined for MD and OCD. Nucleus accumbens (NAcc) comes out among the other targets in patients with MD and comorbid OCD when physiopathology and limited side effects are taken into account. We report a 27-year-old male with MD and OCD who was treated by bilateral NAcc-DBS. The aim of this study is to discuss NAcc as a DBS target in patients with MD and OCD and to report the first case of a psychiatric disorder treated with DBS in Turkey. PMID- 30283562 TI - A Rare Case of Isolated Intracranial Rosai-Dorfman Disease Mimicking Optic Nerve Meningioma: A Case Report and Literature Review. AB - Sinus histiocytosis with massive lymphadenopathy, or Rosai-Dorfman disease (RDD), was first described in 1969 as a reactive condition of unknown etiology that is characterized by a proliferation of histiocytes exhibiting emperipolesis of both lymphocytes and plasma cells. It usually presents with painless cervical lymphadenopathy either with or without extranodal manifestations. Intracranial involvement of this disease is extremely rare. Intracranial RDD occurs in <5% of all patients with extranodal disease. Here, we report a case of RDD with isolated intracranial involvement. A 67-year-old male presented with a long-standing headache, retro-ocular pain, and progressive visual loss of the left eye. Magnetic resonance imaging showed features of optic nerve meningioma. The histopathology revealed sheets of histiocytes displaying emperipolesis. These histiocytes were S100 positive; however, a CD1a and epithelial membrane antigen were negative. PMID- 30283563 TI - Methotrexate-induced Leukoencephalopathy without Typical Restricted Diffusion on Diffusion-weighted Imaging and the Utility of Magnetic Resonance Spectroscopy to Support the Diagnosis. AB - Methotrexate (MTX) is a common antimetabolite agent that is widely used today in treating leukemia, lymphoma, and osteosarcoma. Its use has been associated with leukoencephalopathy causing seizures, paralysis, and even coma. To achieve the best possible outcome, it is important to be able to make a prompt diagnosis. Studies reported restricted diffusion on diffusion-weighted imaging (DWI) which is a reliable early sign of acute MTX-induced leukoencephalopathy. However, we report here the first case of MTX-induced leukoencephalopathy without typical restricted diffusion on DWI and the utility magnetic resonance spectroscopy to support this diagnosis in the difficult case such as the one being presented here. PMID- 30283564 TI - "The Subdural Collection" a Great Simulator: Case Report and Literature Review. AB - Prostate carcinoma rarely develops intracranial metastasis. In case it does, the dura is the most affacted area. In general, brain computed tomography (CT) findings mimic subdural hematoma making surgery challenge. We report the case of a 52-year-old male, presented as an emergency with a month history of headache, progressive temporospatial disorientation, mental confusion, and abrupt consciousness deterioration up to coma occurring few hours prior admission. An urgent brain CT scan showed a subdural collection in favor of a chronic subdural hematoma. The patient underwent surgery by standard burr hole, and surprisingly, peroperatively, there was a very bloody diffuse thickening of the dura without a real hematoma obliging to switch to a large fronto-temporoparietal craniotomy revealing a subdural mass that was completely removed. Histopathology disclosed a metastatic prostatic carcinoma confirming that such a subdural collection could behave as a great simulator. A contrast brain CT scan, is advisable, even in emergency, in selected case, with atypical images finding, especially if, a malignant disease is already known; the former could be of great help in the differential diagnosis and the best prompt management. PMID- 30283565 TI - Intracranial Hypertension Secondary to Cervical Dural Arteriovenous Fistula. AB - Idiopathic intracranial hypertension (IIH) is a disease of mainly unknown etiology. Latest theories as to the pathogenesis have postulated a final common pathway of cerebral venous hypertension secondary to venous outflow impairment leading to decreased cerebrospinal fluid absorption. We present the case of a 42 year-old female who was treated for several years for headache and for approximately 12 months for IIH until appropriate imaging showed a right-sided cervical dural arteriovenous fistula (AVF) at the level of C4. The patient's IIH symptoms resolved following surgical excision of the fistula. We suggest that the cranial venous outflow impairment secondary to the cervical AVF was responsible for intracranial hypertension and that complete investigation of IIH patients should include imaging of the neck vasculature. PMID- 30283566 TI - Iodinated Contrast Encephalopathy after Coil Embolization of Unruptured Aneurysms. AB - Iodinated contrast encephalopathy is known as one of the rare complications of cerebral angiography and neurovascular intervention. The mechanism and causes of contrast encephalopathy are not understood well. In this case, we experienced transient neurological deficit following coil embolization of unruptured aneurysms. A 67-year-old woman with two unruptured aneurysms of internal carotid artery underwent endovascular coil embolization. During the procedure, she presented transient hemiparesis and aphasia. After the treatment, she presented the symptom again, and computed tomography scan showed cortical edema and subarachnoid leakage of contrast agent. Magnetic resonance imaging excluded cerebral infarction. The neurological symptom resolved completely within 24 h after the treatment, and she was diagnosed as the contrast encephalopathy. In our case, we speculated that contrast encephalopathy has occurred subsequently to the transient cerebral ischemia. Iodinated contrast encephalopathy may have induced with neurovascular intervention following cerebral ischemia and increased use of contrast agent. We should consider iodinated contrast encephalopathy when a patient presents hemiparesis and aphasia such as that caused by acute stroke during neurovascular intervention. PMID- 30283567 TI - Persistent Primitive Trigeminal Artery Associated With Anterior Communicating Artery Aneurysm and Hypoplastic Vertebral Artery. AB - The persistent trigeminal artery is one of the presegmental arteries in the embryonic period; in some rare cases, it is associated with cerebral aneurysm but as a cause of subarachnoid hemorrhage (SAH) has not been described in the literature. We report a patient who presented a Fisher IV SAH associated with a ruptured intracranial aneurysm. The performed cerebral angiography demonstrated the presence of aneurysm in the anterior communicating artery associated to hypoplastic vertebral artery on the same side. We considered those finding coincidental. The coexistence of saccular aneurysm with anatomical variations in the intracranial vasculature is briefly discussed. It was managed by endovascular embolization. The patient returned to normal activities. PMID- 30283569 TI - Delayed Paraplegia in an Adult Patient With Spinal Cord Injury without Radiographic Abnormality of Dorsal Spine: A Lesson Learned. AB - Noncompressive myelopathy of lower dorsal spine secondary to trauma is a rare event. We report a case of delayed paraplegia in a patient with a history of road traffic accident. The X-ray of dorsolumbar spine did not show any abnormality. Magnetic resonance imaging of dorsolumbar spine was performed which showed the presence of central T2-weighted hyperintensities from D10-D11 to D12-L1 level. No associated bony injury was documented, and the integrity of the spinal canal was maintained. The patient was managed conservatively with bed rest, and steroids were given. However, the patient did not show any signs of improvement after 1 month of follow-up. PMID- 30283568 TI - Paraneoplastic Nephrotic Syndrome in a Patient with Planum Sphenoidale Meningioma. AB - A 60-year-old homemaker presenting with pedal edema and ascites was found to have a planum sphenoidale meningioma concurrently with nephrotic syndrome. On renal biopsy, the patient was found to have membranous glomerulonephritis. There was complete remission of nephropathy after excision of the meningioma. Nephrotic syndrome has been commonly found in association with malignancies and blood disorders but the association with a meningioma is extremely rare, and only one case has been previously reported as per our knowledge. PMID- 30283571 TI - Pediatric Suprasellar Atypical Teratoid Rhabdoid Tumor Arising from the Third Ventricle: A Rare Tumor at a Very Rare Location. AB - Atypical teratoid rhabdoid tumor (ATRT) is a rare, highly malignant tumor of the central nervous system, commonly affecting children below 3 years of age, with around 300 cases reported in the literature. Suprasellar area is a very rare location for such tumor in the pediatric population, with technical difficulties in complete excision. Third ventricular ATRT is very rare. Here, we report the case of a 2-year-old male child who presented with lethargy and vomiting. He had features of raised intracranial pressure with reduced vision in both eyes. Magnetic resonance imaging of the brain revealed a heterogeneously enhancing lobulated giant lesion in the suprasellar location, occupying the third ventricle and hypothalamus with encasement of both carotids. He underwent pericoronal parasagittal craniotomy, interhemispheric transcallosal interforniceal approach and gross total excision of the lesion. Postoperatively, the child had altered sensorium and diabetes insipidus, both of which recovered over a span of 10 days. Histopathological examination of the specimen was consistent with the diagnosis of World Health Organization Grade IV ATRT. In spite of all our efforts, he succumbed to his illness 5 months postoperatively. PMID- 30283570 TI - Delayed Occurrence of C3 Vertebra Anterior Subluxation Diagnosed after Surgery for Epidural Hematoma. AB - A case of delayed occurrence of C3 vertebra anterior subluxation diagnosed 10 days after surgery for epidural hematoma is herein described. A 56-year-old man underwent surgery for right epidural hematoma. No spinal fracture was identified on the cervical-spinal computed tomography (CT) on arrival. The patient developed neck pain after the craniotomy, and cervical magnetic resonance imaging 5 days postoperatively revealed a disruption of the C3-C4 posterior ligament complex. The patient was conservatively treated with immobilization. Cervical CT 10 days postoperatively revealed C3 vertebra anterior subluxation. Posterior fixation surgery was performed 21 days after admission, and the postoperative course was uneventful. This case suggests that awareness of delayed occurrence of cervical dislocation after traumatic intracranial hemorrhage should be increased among neurosurgeons. PMID- 30283572 TI - A Rare Case Report of Giant Cell Tumor of the Sphenoid Bone in a Patient Who Developed "Erythema Multiforme Associated with Phenytoin and Cranial Radiation Therapy Syndrome". AB - Giant cell tumors (GCTs) are rare, usually affecting the epiphyses in long bones of the extremities. GCTs may be locally aggressive with a high rate of local recurrence and exhibit the potential for distant metastasis. They seldom occur in the skull, where they preferentially affect the sphenoid and temporal bones. Several case reports with follow-up describe gross total resection of skull-base GCT to be curative. Radiation therapy, although controversial, is reserved for lesions that cannot be completely resected. Here, we describe the case of an 18 year-old female with GCT of sphenoid bone who underwent subtotal resection followed by adjuvant radiotherapy, although whose radiotherapy could not be completed because of her demise due to erythema multiforme associated with phenytoin and cranial radiation therapy syndrome. PMID- 30283573 TI - Melanotic Schwannoma of Spine: Illustration of Two Cases with Diverse Clinical Presentation and Outcome. AB - Melanotic schwannomas (MS) are rare variants of schwannomas the occurrence of which is described in case reports only. They usually arise from posterior spinal nerve roots and less commonly from other cells of neural crest origin. Although they are relatively benign tumors in young, aggressive behavior is reported. They occur as isolated tumors or as part of a syndrome named Carney complex. We try to describe the pathology, diagnosis, management, and prognosis of MSs in two different cases: one cervical intramedullary with no recurrence on 5-year follow up and the other one extramedullary in lumbar region with early recurrence and aggressive course. A brief review of literature is done. PMID- 30283574 TI - A Rare Case of Simultaneous Multifocal Craniospinal Hemangiopericytomas. AB - First reported case of simultaneous occurrence of hemangiopericytomas(HCP) at multiple sites of craniospinal axis in a thirty four year male is presented. Patient presented with neck pain for 1 year, and one episode of simple partial seizure involving his left lower limb. He was diagnosed as having HCP in right middle one third parasagittal region, and C4,5 vertebral bodies. Another lesion was present in L5 vertebra, which was radiologically similar to the cervical lesion, but not biopsy proven. High index of suspicion, and low threshold for screening, for coexistence of spinal HCP, in patients harboring cranial HCP's and complaints of back pain. PMID- 30283576 TI - Management of Recurrent Tumefactive Multiple Sclerosis: Case Report and Literature Review. AB - Tumefactive multiple sclerosis (MS) is characterized by the presence of a single MS-plaque in the brain. It mimics tumors due to large size, mass effect, and enhancement patterns. Refractory intracranial hypertension due to tumefactive MS requiring decompressive craniectomy (DC) was reported in five cases. However, none of these cases were documented new lesions during the follow-up. We report a case of a 28-year-old female admitted with acute right hemiparesis, headache, and nausea. A brain magnetic resonance imaging (MRI) revealed a left parietal lobe lesion. Within 4 days, she became comatose. Computed tomography (CT) scan revealed the left uncal herniation. DC and resection of the lesion were carried out. Histopathology revealed active demyelinating disease. After 11 years of the first attack, she went to the emergency department due to headache and left hemiparesis. Head CT scan revealed a hypodense area in the right frontal lobe. Three months later, the patient was asymptomatic, and new MRI did not show new lesions. PMID- 30283575 TI - The Role of Endoscopic Endonasal Approach in the Multimodal Management of Giant Pituitary Adenoma: Case Report and Literature Review. AB - Giant pituitary adenomas (GPAs) are defined as pituitary lesions larger than 40 mm of diameter. Surgical resection remains the gold standard to decompress the optic apparatus, reduce lesion load, and preserve hormonal function. The endoscopic endonasal approach (EEA) has been increasingly used for the treatment of pituitary adenomas and skull base tumors due to the wide angle of view and exposure. Through the description of an exemplificative case of EEA resection of a nonsecreting GPA in the setting of a multimodal treatment, the authors discuss the advantages and disadvantages of this management strategy and provide a detailed review of the literature. PMID- 30283577 TI - Feasibility of a Fourth Ventriculopleural Shunt for Diversion of an Isolated Fourth Ventricle: A Technical Note. AB - Isolated fourth ventricle syndrome is an uncommon entity due to obstruction of both inlet and outflow foramina. The resulting mass effect from the progressively expanding fourth ventricle may cause symptoms from both cerebellar and brainstem compression. Although a variety of treatment modalities have been advocated for this condition, an in-depth description of placement of a fourth ventriculopleural (VPL) shunt from a single-stage prone approach has not yet been published in the literature. We describe here a case of successful placement of a fourth VPL shunt in a 22-year-old female with a history of a prior posterior fossa pilocytic astrocytoma resection who presented with symptomatic isolated fourth ventricular hydrocephalus. PMID- 30283578 TI - Recurrent Embolic Stroke Caused by Large Cavernous Carotid Aneurysm: Stroke Recurrence Prevention with High-Flow Bypass Followed by Proximal Occlusion. AB - Intracranial aneurysms may cause embolic stroke. Medical or surgical management is selected on an individual basis, as the optimal treatment strategy has not been established. A 79-year-old woman with a large cavernous carotid aneurysm suffered repeated embolic stroke after enlargement and partial thrombosis of the aneurysm, in spite of antiplatelet therapy. Coil embolization of the primitive trigeminal artery and ligation of the internal carotid artery (ICA) at the cervical portion followed by high-flow bypass from the cervical external carotid artery to the middle cerebral artery were performed. The aneurysm was thrombosed, and prevention of further stroke was achieved. Acute enlargement and thrombosis of large or giant cavernous carotid aneurysm may cause repeated embolic stroke, and requires emergent exclusion of the aneurysm from circulation by proximal ICA occlusion together with distal revascularization before devastating embolic stroke occurs. PMID- 30283579 TI - Traumatic Chance Fracture of Cervical Spine: A Rare Fracture Type and Surgical Management. AB - Cervical spine chance fracture (flexion-distraction) is a rare type of fracture, and the surgical management remains a dilemma to the neurosurgeons as there is a paucity of evidence accordingly. We herein report a traumatic chance fracture of C7 fractures and its surgical management. A 33-year-old male was transferred to our center after being hit as pedestrian and was diagnosed to have a chance fracture of C7 and bilateral C7 root injury. He underwent open reduction of the deformity by posterior-only fixation of C5 and C6 with a lateral mass screw and T1 and T2 with pedicular screws. The neurological examination improved postoperatively, and the patients were neurologically intact after 6 months of treatment. Traumatic cervical spine chance fracture is extremely rare and can be managed surgically through posterior fixation and open reduction of the deformity. The best choice of treatment is limited by the paucity of the evidence and should be individualized. PMID- 30283580 TI - Dissecting Aneurysm of Vertebral Artery Involving the Origin of Posteroinferior Cerebellar Artery Treated with Retrograde Stent Placement and Coil Embolization in the Era of Flow Diverter. AB - Ruptured vertebral artery (VA) dissecting aneurysm carries high risk of rerupture and mortality if not treated immediately. Dissecting aneurysm of the VA involving the posteroinferior cerebellar artery (PICA) origin is difficult to treat by surgical and endovascular route. With the availability of flow diversion device for reconstructive procedure, endovascular treatment has now become easy to treat difficult aneurysm while maintaining the patency of the PICA. However, instead of using flow diverter (FD) in our case, we successfully treated dissecting VA aneurysm involving the PICA origin with retrograde stent placement from distal right VA to the left PICA to maintain the patency of PICA and occlusion of dissecting aneurysm of VA with detachable coils instead of performing surgical bypass and FD placement. PMID- 30283581 TI - Iatrogenic (Traumatic) Occipital Artery Pseudoaneurysm - Rare Complication of Ventriculoperitoneal Shunt in an Infant: Case Report and Review of the Literature. AB - Although ventriculoperitoneal shunt (VPS) is the most common procedure performed by pediatric neurosurgeons, it is still associated with frustrating complications, most common of which are obstruction and infection. Traumatic occipital artery pseudoaneurysm is a very rare complication of VPS procedure. To the best of our knowledge, there is no similar case reported in the English language literature. A 12-month-old patient suffered posthemorrhagic hydrocephalus of prematurity, and multiple other complications due to extreme prematurity, including immature lung disease, retinopathy of prematurity, necrotizing enterocolitis, bowel perforation, short bowel syndrome resulting in total parenteral nutrition-dependence, and hydrocephalus which was treated by insertion of VPS. Four weeks after the shunt, a slowly enlarging pulsatile swelling distal to the valve under the catheter altering the shunt function was noted. The swelling was diagnosed as a pseudoaneurysm of the occipital artery and treated by excision of the aneurysm. The child developed isolated dilated fourth ventricle, which was treated by endoscopic fourth ventriculostomy. Traumatic occipital artery pseudoaneurysm as a result of tunneling of VPS catheter is a very rare complication of VPS. Clinical and radiological imaging is diagnostic of the aneurysm. Surgical repair should be considered in such cases. This case report is aimed to raise the awareness among physicians about this rare complication. PMID- 30283582 TI - Natural History of Medulloblastoma in a Child with Neurofibromatosis Type I. AB - Medulloblastoma is one of the common posterior fossa tumors in children. The natural history of this tumor in presymptomatic period is not well known. Widespread use of brain imaging has increased the detection of incidental brain tumors in totally asymptomatic persons. Here, we report a case of a 4-year-old boy with prenatal diagnosis of congenital brain abnormalities and neurofibromatosis type I. He underwent regular brain imaging to follow interhemispheric arachnoid cyst and ventriculomegaly that a posterior fossa tumor was discovered. The tumor size increased during time and became symptomatic after 28 months which was resected. PMID- 30283583 TI - Heterotrophic Ossification of the Flexor Retinaculum in a Patient with Ankylosing Spondylitis. AB - Carpal tunnel syndrome (CTS) is the most common peripheral neuropathy. This syndrome has various etiologies of which heterotopic ossification of the flexor retinaculum is a rare cause. Ankylosing spondylitis (AS) is a systemic, progressive inflammatory disease of unknown etiology that mainly affects the axial skeleton and rarely causes peripheral neurological symptoms. A 48-year-old woman presented with numbness and pain in her right hand. Ten years earlier, she was diagnosed with AS. Electrodiagnostic evaluation revealed severe median nerve compression at the right wrist. The patient underwent surgery for severe CTS. During the operation, the flexor retinaculum could not be incised due to marked stiffness. Ossification of the flexor retinaculum was seen, and the retinaculum was partially excised with an osteotome and Kerrison rongeur. The patient's complaints resolved almost totally after the operation. AS is a common systemic inflammatory disease that can produce heterotopic ossification of the flexor retinaculum. Preoperative wrist computed tomography should be obtained in patients with CTS and AS. PMID- 30283584 TI - Primary Intracranial Manifestation of a Carcinosarcoma. AB - Carcinosarcomas are tumors comprising part adenocarcinoma and part sarcoma; the presence of carcinosarcoma in the head-and-neck region is very rare. These tumors are typically highly aggressive (G3) and arise most frequently from the salivary gland. Here, we present a case report on a brain metastasis as the primary manifestation of a carcinosarcoma. Magnetic resonance imaging showed a tumor of the pineal region with infiltration of the brainstem and the corpus. The staging following the histopathological diagnosis revealed the origin of the tumor in the left parotid gland. We present an overview of the significance of published treatment strategies in carcinosarcoma. PMID- 30283585 TI - Intradural Extramedullary Tuberculoma Masquerading En Plaque Meningioma. AB - Extensive en plaque intradural extramedullary tuberculomas can occur as a paradoxical response to chemotherapy for intracranial tuberculomas. We report a case of 31-year-old male who presented with backache and progressive weakness and urgency of micturition. Magnetic resonance imaging dorsolumbar spine which showed an ill-defined T1 hypointense and T2 heterointense lesion noted posterior to the thoracic spinal cord, extending from C7 to D5 vertebral levels suggestive of en plaque meningioma. The patient underwent D1-D5 laminectomy, with subtotal debulking of the tumor. The histopathological examination of lesion was suggestive of granulomatous inflammation with multinucleated and Langhan type giant cells confirming the diagnosis of tuberculoma. PMID- 30283586 TI - Subdural Hematoma as a Consequence of Labor Epidural Analgesia. AB - Subdural hematoma (SDH) following labor epidural analgesia is a rare neurological complication. SDH is a late complication of this procedure; it is caused by a leak of cerebrospinal fluid that may damage the vascular structures of the brain. Persistent headache in the days after labor epidural analgesia is a nonspecific clinical symptom caused by hematoma. Preexisting vascular malformations can be a concomitant cause of headache. Clinical cases have been reported even after epidural anesthesia. The differential diagnosis includes unspecified headache, sinusitis headache, drug-induced headache, cortical vein thrombosis, fistula of the dura mater, and bacterial, viral, and aseptic meningitis. PMID- 30283587 TI - Isolated Orbital Roof Fracture: Can It Be Catastrophic? AB - Orbital encephalocele is a rare catastrophic complication of orbital roof fractures. Early diagnosis of this posttraumatic orbital encephalocele is very crucial because this condition if untreated leads to rapid loss of vision. Whenever displaced orbital roof fracture is identified in a head injury patient, an orbital encephalocele should be suspected. Although magnetic resonance imaging is the investigation of choice, computed tomography of orbit with thin axial and coronal sequences often gives the diagnosis. Frontobasal approach is the most commonly used surgical approach. Supra-transorbital approach is a minimally invasive alternative. Good results with regard to the orbital symptoms can be expected. PMID- 30283588 TI - Cerebral Bypass Surgery for Internal Carotid Artery Occlusion, Complex Supraclinoid Carotid Artery Aneurysm, and Tumors: A Report of Four Cases. AB - Despite growing popularity of endovascular techniques, certain subsets of patients with cerebrovascular compromise may benefit from bypass surgery. We present four cases in which pending ischemic lesion was prevented by (1) A3 resection and reanastomosis following falx meningioma removal, (2) rescue superficial temporal artery-middle cerebral artery (STA-MCA) bypass after pituitary adenoma surgery, (3) STA-MCA bypass for chronic internal carotid artery occlusion, and (4) external carotid artery-MCA bypass using radial artery grafting. Following the procedure, there were no further clinical or radiological deteriorations and long-term patency was confirmed in all four cases. PMID- 30283590 TI - Trans-Cranial Embolisation of a Complex Transverse Sigmoid Sinus Dural Arteriovenous Fistula by Direct Puncture of the Superior Sagittal Sinus. AB - This technical note describes a direct puncture of the superior sagittal sinus (SSS) to treat a complex dural arteriovenous fistula (dAVF). A 40-year-old female was admitted having a history of increasing confusion. Computer tomography revealed enlargement of the right superior ophthalmic vein and magnetic resonance imaging demonstrated extensive bilateral hemispheric venous engorgement. Digital subtraction angiography (DSA) demonstrated a high flow dAVF involving the right transverse sinus. There was extensive cortical venous rerouting with venous sinus occlusion at the right transverse and sigmoid junction. Under general anesthesia, the sinus was exposed and catheterized. The angiography catheter was fed over the guide wire into the sinus. The remaining right sigmoid and transverse sinus were obliterated using a combination of microcoils and Onyx(r). She made a good postoperative recovery, and a repeat DSA at 30 days postoperatively showed evidence of the meningohypophyseal trunk but complete occlusion of the fistula. A check DSA 2 years later confirmed no evidence of a residual fistula. Our case demonstrates the potential use of the SSS as a novel conduit to treat distant targets. PMID- 30283589 TI - The Orbitomeningeal Band as a Way to Bloodless Transcavernous Dissection and Anterior Clinoidectomy. AB - The meningo-orbital band (MOB) is a dural fold which runs along the lateral border of the superior orbital fissure and contains few small dural veins and the orbitomeningeal artery. MOB detachment is relatively easy to understand step-wise procedure, provides a wider exposure, and better orientation thus facilitating relatively easy approach to paraclinoid and cavernous sinus region. The present microsurgical technique helps to preserve the true cavernous membrane and thereby providing almost bloodless dissection of the cavernous sinus. The same technique can be used to uncover the anterior clinoid process laterally, posteriorly, superiorly, and also in the inferolateral region thereby decreasing the risk and time of clinoidectomy.

AB - Introduction: There is wide variation in the success rates of practitioners employed to help smokers to stop, even once a range of potential confounding factors has been taken into account. Aim: This paper examined whether personality characteristics of practitioners might play a role success rates. Methods: Data from 1,958 stop-smoking treatment episodes in two stop-smoking services (SSS) involving 19 stop-smoking practitioners were used in the analysis. The outcome measure was clients' biochemically verified quit status 4 weeks after the target quit date. The five dimensions of personality, as assessed by the Ten-Item Personality Inventory, were included as predictor variables: openness, conscientiousness, agreeableness, extraversion, and neuroticism. A range of client and other practitioner characteristics were used as covariates. A sensitivity analysis was conducted to determine if managers' ratings of practitioner personality were also associated with clients' quit status. Results: Multi-level random intercept models indicated that clients of practitioners with a higher extraversion score had greater odds of being abstinent at four weeks (self-assessed: OR = 1.10, 95% CI = 1.01-1.19; manager-assessed: OR = 1.32, 95% CI = 1.21-1.44). Conclusions: More extraverted stop smoking practitioners appear to have greater success in advising their clients to quit smoking. Findings need to be confirmed in larger practitioner populations, other SSS, and in different smoking cessation contexts. If confirmed, specific training may be needed to assist more introverted stop smoking practitioners. PMID- 30283597 TI - Clinical update on the management of pseudopapillary tumor of pancreas. AB - Solid pseudopapillary neoplasm (SPN) is a rare tumor with malignant potential which is generally located in the tail of pancreas. The prevalence of SPN has increased with widespread use of cross sectional imaging. SPN is often misdiagnosed due to nonspecific clinical presentation and accurate diagnosis is essential for optimal management. Endoscopic ultrasound-FNA with immunohistochemistry can help in preoperative diagnosis. Surgery is the treatment of choice and a successful R0 resection is curative. Overall, SPN has a good prognosis. This review article focuses on pathogenesis, diagnosis and management of SPN. PMID- 30283598 TI - Endoscopic diagnosis and treatment of superficial non-ampullary duodenal tumors. AB - The diagnostic and treatment guidelines of superficial non-ampullary duodenal tumors have not been standardized due to their low prevalence. Previous reports suggested that a superficial adenocarcinoma (SAC) should be treated via local resection because of its low risk of lymph node metastasis, whereas a high-grade adenoma (HGA) should be resected because of its high risk of progression to adenocarcinoma. Therefore, pretreatment diagnosis of SAC or HGA is important to determine the appropriate treatment strategy. There are certain endoscopic features known to be associated with SAC or HGA, and current practice prioritizes the endoscopic and biopsy diagnosis of these conditions. Surgical treatment of these duodenal lesions is often related to high risk of morbidity, and therefore endoscopic resection has become increasingly common in recent years. Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are the commonly performed endoscopic resection methods. EMR is preferred due to its lower risk of adverse events; however, it has a higher risk of recurrence than ESD. Recently, a new and safer endoscopic procedure that reduces adverse events from EMR or ESD has been reported. PMID- 30283600 TI - Proposed approach to the challenging management of progressive gastroesophageal reflux disease. AB - The progression of gastroesophageal reflux disease (GERD) in patients who are taking proton pump inhibitors (PPIs) has been reported by several investigators, leading to concerns that PPI therapy does not address all aspects of the disease. Patients who are at risk of progression need to be identified early in the course of their disease in order to receive preventive treatment. A review of the literature on GERD progression to Barrett's esophagus and the associated physiological and pathological changes was performed and risk factors for progression were identified. In addition, a potential approach to the prevention of progression is discussed. Current evidence shows that GERD can progress; however, patients at risk of progression may not be identified early enough for it to be prevented. Biopsies of the squamocolumnar junction that show microscopic intestinalization of metaplastic cardiac mucosa in endoscopically normal patients are predictive of future visible Barrett's esophagus, and an indicator of GERD progression. Such changes can be identified only through biopsy, which is not currently recommended for endoscopically normal patients. GERD treatment should aim to prevent progression. We propose that endoscopically normal patients who partially respond or do not respond to PPI therapy undergo routine biopsies at the squamocolumnar junction to identify histological changes that may predict future progression. This will allow earlier intervention, aimed at preventing Barrett's esophagus. PMID- 30283599 TI - Endoscopic therapy for Barrett's esophagus and early esophageal cancer: Where do we go from here? AB - Since Barrett's esophagus is a precancerous condition, efforts have been made for its eradication by various ablative techniques. Initially, laser ablation was attempted in non-dysplastic Barrett's esophagus and subsequently, endoscopic ablation using photodynamic therapy was used in Barrett's patients with high grade dysplasia who were poor surgical candidates. Since then, various ablative therapies have been developed with radiofrequency ablation having the best quality of evidence. Resection of dysplastic areas only without complete removal of entire Barrett's segment is associated with high risk of developing metachronous neoplasia. Hence, the current standard of management for Barrett's esophagus includes endoscopic mucosal resection of visible abnormalities followed by ablation to eradicate remaining Barrett's epithelium. Although endoscopic therapy cannot address regional lymph node metastases, such nodal involvement is present in only 1% to 2% of patients with intramucosal adenocarcinoma in Barrett esophagus and therefore is useful in intramucosal cancers. Post ablation surveillance is recommended as recurrence of intestinal metaplasia and dysplasia have been reported. This review includes a discussion of the technique, efficacy and complication rate of currently available ablation techniques such as radiofrequency ablation, cryotherapy, argon plasma coagulation and photodynamic therapy as well as endoscopic mucosal resection. A brief discussion of the emerging technique, endoscopic submucosal dissection is also included. PMID- 30283602 TI - Anesthetic management and associated complications of peroral endoscopic myotomy: A case series. AB - AIM: To investigate the anesthetic management of peroral endoscopic myotomy (POEM) and its associated complications. METHODS: This study was a single-center, retrospective, observational study comprising a case series of all patients who underwent POEM in our hospital from April 2015 to November 2016. We collected data regarding patient characteristics, anesthetic methods, surgical factors, and complications using an electronic chart. RESULTS: There were 86 patients who underwent POEM in our hospital during the study period. Preoperatively, patients were maintained on a low residue diet for 48 h prior to the procedure. They were fasted of solids for 24 h before surgery. There was one case of aspiration (1.2%). During POEM, patients were positioned supine with the upper abdomen covered by a clear drape so that pneumoperitoneum could be timeously identified. In three cases, the peak airway pressure exceeded 35 cmH2O during volume controlled ventilation with tidal volumes of 6-8 mL/kg and subsequent impairment of ventilation. These cases had been diagnosed with spastic esophageal disorders (SEDs) and the length of the muscular incision on the esophageal side was longer than normal. CONCLUSION: In the anesthetic management of POEM, it is important to prevent aspiration during induction of anesthesia and to identify and treat complications associated with CO2 insufflation. PMID- 30283601 TI - Capsule endoscopy: Current status and role in Crohn's disease. AB - Capsule endoscopy (CE) has proved to be an important non-invasive tool for diagnosis and monitoring Crohn's disease patients. It has the advantage of excellent visualization of digestive tract mucosa, a good tolerability and safety in well-selected patients. The risk of retention can be diminished by good selection of patients using imaging techniques and by the use of patency capsule. The aim of a capsule examination is not only an early diagnosis but also a very good stratification of prognosis, thus directing the treatment strategy for either a step up or top-down approach and also permitting the optimization of the treatment depending on the findings. When symptoms and biomarkers point to a change in the disease's activity we can either adjust the treatment directly as recommended in CALM study or choose in selected patients to visualize the digestive mucosa through a CE and take a decision afterwards. The appearance of the new capsule from Medtronic-the Pillcam Crohn's might be an important step forward in diagnosis, evaluating disease extent, the severity of the disease, prognosis, management in a treat to target approach, with treatment modifications according to the data from CE examination. Serial examinations in the same patient can be compared and a more objective evaluation of the lesions modification from one exam to another can be performed. We present the latest developments and current status and evidence that in selected patients capsule can be a tool in a treat to target approach. PMID- 30283603 TI - Frequency of hospital readmission and care fragmentation in gastroparesis: A nationwide analysis. AB - AIM: To evaluate rates and predictors of hospital readmission and care fragmentation in patients hospitalized with gastroparesis. METHODS: We identified all adult hospitalizations with a primary diagnosis of gastroparesis in the 2010 2014 National Readmissions Database, which captures statewide readmissions. We excluded patients who died during the hospitalization, and calculated 30 and 90-d unplanned readmission and care fragmentation rates. Readmission to a non-index hospital (i.e., different from the hospital of the index admission) was considered as care fragmentation. A multivariate Cox regression model was used to analyze predictors of 30-d readmissions. Logistic regression was used to determine hospital and patient factors independently associated with 30-d care fragmentation. Patients readmitted within 30 d were followed for 60 d post discharge from the first readmission. Mortality during the first readmission, hospitalization cost, length of stay, and rates of 60-d readmission were compared between those with and without care fragmentation. RESULTS: There were 30064 admissions with a primary diagnosis of gastroparesis. The rates of 30 and 90-d readmissions were 26.8% and 45.6%, respectively. Younger age, male patient, diabetes, parenteral nutrition, >= 4 Elixhauser comorbidities, longer hospital stay (> 5 d), large and metropolitan hospital, and Medicaid insurance were associated with increased hazards of 30-d readmissions. Gastric surgery, routine discharge and private insurance were associated with lower 30-d readmissions. The rates of 30 and 90-d care fragmentation were 28.1% and 33.8%, respectively. Younger age, longer hospital stay (> 5 d), self-pay or Medicaid insurance were associated with increased risk of 30-d care fragmentation. Diabetes, enteral tube placement, parenteral nutrition, large metropolitan hospital, and routine discharge were associated with decreased risk of 30-d fragmentation. Patients who were readmitted to a non-index hospital had longer length of stay (6.5 vs 5.8 d, P = 0.03), and higher mean hospitalization cost ($15645 vs $12311, P < 0.0001), compared to those readmitted to the index hospital. There were no differences in mortality (1.0% vs 1.3%, P = 0.84), and 60-d readmission rate (55.3% vs 54.6%, P = 0.99) between the two groups. CONCLUSION: Several factors are associated with the high 30-d readmission and care fragmentation in gastroparesis. Knowledge of these predictors can play a role in implementing effective preventive interventions to high-risk patients. PMID- 30283604 TI - Randomised controlled trial comparing modified Sano's and narrow band imaging international colorectal endoscopic classifications for colorectal lesions. AB - AIM: To assess the utility of modified Sano's (MS) vs the narrow band imaging international colorectal endoscopic (NICE) classification in differentiating colorectal polyps. METHODS: Patients undergoing colonoscopy between 2013 and 2015 were enrolled in this trial. Based on the MS or the NICE classifications, patients were randomised for real-time endoscopic diagnosis. This was followed by biopsies, endoscopic or surgical resection. The endoscopic diagnosis was then compared to the final (blinded) histopathology. The primary endpoint was the sensitivity (Sn), specificity (Sp), positive predictive value (PPV) and negative predictive value (NPV) of differentiating neoplastic and non-neoplastic polyps (MS II/IIo / IIIa / IIIb vs I or NICE 1 vs 2/3). The secondary endpoints were "endoscopic resectability" (MS II/IIo/IIIa vs I/IIIb or NICE 2 vs 1/3), NPV for diminutive distal adenomas and prediction of post-polypectomy surveillance intervals. RESULTS: A total of 348 patients were evaluated. The Sn, Sp, PPV and NPV in differentiating neoplastic polyps from non-neoplastic polyps were, 98.9%, 85.7%, 98.2% and 90.9% for MS; and 99.1%, 57.7%, 95.4% and 88.2% for NICE, respectively. The area under the receiver operating characteristic curve (AUC) for MS was 0.92 (95%CI: 0.86-0.98); and AUC for NICE was 0.78 (95%CI: 0.69, 0.88). The Sn, Sp, PPV and NPV in predicting "endoscopic resectability" were 98.9%, 86.1%, 97.8% and 92.5% for MS; and 98.6%, 66.7%, 94.7% and 88.9% for NICE, respectively. The AUC for MS was 0.92 (95%CI: 0.87-0.98); and the AUC for NICE was 0.83 (95%CI: 0.75-0.90). The AUC values were statistically different for both comparisons (P = 0.0165 and P = 0.0420, respectively). The accuracy for diagnosis of sessile serrated adenoma/polyp (SSA/P) with high confidence utilizing MS classification was 93.2%. The differentiation of SSA/P from other lesions achieved Sp, Sn, PPV and NPV of 87.2%, 91.5%, 89.6% and 98.6%, respectively. The NPV for predicting adenomas in diminutive rectosigmoid polyps (n = 150) was 96.6% and 95% with MS and NICE respectively. The calculated accuracy of post polypectomy surveillance for MS group was 98.2% (167 out of 170) and for NICE group was 92.1% (139 out of 151). CONCLUSION: The MS classification outperformed the NICE classification in differentiating neoplastic polyps and predicting endoscopic resectability. Both classifications met ASGE PIVI thresholds. PMID- 30283605 TI - Successful stent-in-stent dilatation of the common bile duct through a duodenal prosthesis, a novel technique for malignant obstruction: A case report and review of literature. AB - For patients suffering from both biliary and duodenal obstruction, endoscopic retrograde cholangiopancreatography (ERCP) with stent placement is the treatment of choice. ERCP through an already existing duodenal prosthesis is an uncommon procedure and furthermore no studies have reported installing a covered metal stent onto an already existing bare metal stent in the common bile duct (CBD). We describe a rare case of a stent-in-stent dilatation of the CBD through an already existing self-expanding metal stent in the second part of duodenum for the patient presenting with jaundice in setting of biliary and duodenal obstruction from pancreatic adenocarcinoma. The biliary obstruction was relieved with a decrease in bilirubin levels post-stenting. PMID- 30283607 TI - Inverted Meckel's diverticulum: Two case reports and a review of the literature. AB - Gastrointestinal surgeons seldom encounter inverted Meckel's diverticulum in their clinical practice. We describe two cases of inverted Meckel's diverticulum. If the patient has a disease-related complication such as intussusception, as with our first case, it can be easily detected. However, if the patient has subacute or chronic symptoms, as with our second case, the diagnosis might be delayed. Regardless of the disease-related complication, intussusception of inverted Meckel's diverticulum can be easily managed with laparoscopic single port surgery.

METHODS: A systematic search of MEDLINE, Cochrane and EMBASE was performed. Rate of cystic duct leakage (CDL) was the primary outcome. Risk of bias was evaluated. Odds ratios were analyzed for comparison of techniques and pooled event rates for non comparative analyses. Pooled event rates were compared for each of included techniques. RESULTS: Out of 1491 articles, 38 studies were included. A total of 47491 patients were included, of which 38683 (81.5%) underwent cystic duct closure with non-locking (metal) clips. All studies were of low-moderate methodological quality. Only two studies reported separate data on uncomplicated and complicated gallbladder disease. For overall CDL, an odds ratio of 0.4 (95%CI: 0.06-2.48) was found for harmonic energy vs clip closure and an odds ratio of 0.17 (95%CI: 0.03-0.93) for locking vs non-locking clips. Pooled CDL rate was around 1% for harmonic energy and metal clips, and 0% for locking clips and ligatures. CONCLUSION: Based on available evidence it is not possible to either recommend or discourage any of the techniques for cystic duct closure during LC with respects to CDL, although data point out a slight preference for locking clips and ligatures vs other techniques. No separate recommendation can be made for complicated gallbladder disease. PMID- 30283609 TI - Readability of Colorectal Cancer Online Information: A Brief Report. AB - Purpose: Colorectal cancer (CRC) is the third leading cause of cancer-related death in the United States. A decline in deaths caused by CRC has been largely attributable to screening and prompt treatment. Motivation, shown to influence cancer-related screening and treatment decisions, can be shaped by information from the Internet. The extent to which this information is easily readable on cancer-related websites is not known. The purpose of this study was to assess the readability levels of CRC information on 100 websites. Methods: Using methods from a prior study, the keyword, "colorectal cancer," was searched on a cleared Internet browser. Scores for each website (n = 100) were generated using five commonly recommended readability tests. Results: All five tests demonstrated difficult readability for the majority of the websites. Conclusions: Online information related to CRC is difficult to read and highlights the need for developing cancer-related online material that is understandable to a wider audience. PMID- 30283608 TI - Treat patient, not just the disease: holistic needs assessment for haematological cancer patients. AB - Haematological malignancies can have devastating effects on the patients' physical, emotional, psycho-sexual, educational and economic health. With the improvement of therapies patients with these malignancies are living longer, however significant proportion these patient show poor quality of life (QoL) due to various physical and psychological consequences of the disease and the treatments. Health-related QoL (HRQoL) is multi-dimensional and temporal, relating to a state of functional, physical, psychological and social/family well being. Compared with the general population, HRQoL of these patients is worse in most dimensions. However without routine holistic need assessment (HNA), clinicians are unlikely to identify patients with clinically significant distress. Surviving cancer is a chronic life-altering condition with several factors negatively affecting their QoL, such as psychological problems, including depression and excessive fear of recurrence, as well as social aspects, such as unemployment and social isolation. These need to be adequately understood and addressed in the healthcare of long-term survivors of haematological cancer. Applying a holistic approach to patient care has many benefits and yet, only around 25% of cancer survivors in the UK receive a holistic needs assessment. The efforts of the last decade have established the importance of ensuring access to psychosocial services for haematological cancer survivors. We need to determine the most effective practices and how best to deliver them across diverse settings. Distress, like haematological cancer, is not a single entity, and one treatment does not fit all. Psychosocialoncology needs to increase its research in comparative effectiveness. PMID- 30283610 TI - Pharmacological and Non-pharmacological Means for Prevention of Fractures among Elderly. AB - Fractures are major cause of morbidity, mortality, and healthcare and social services expenditure in elderly. Fractures often have multifactorial etiologies and the condition emerges due to the interaction between the different predisposing and precipitating factors. One of the most common causes leading to fractures after minimal trauma in older people is osteoporosis. The objective of this article is to describe the clinical concept and summarize the evidence and to explain the future directions for research, focusing on specific issues related to prevent fracture in the elderly. This study reviewed the scientific literature addressing strategies for primary and secondaryprevention of fractures among elderly in the context of pharmacological and non-pharmacological means. A growing body of scientific evidence supports the use of both non-pharmacological and pharmacological interventions for the prevention of fracture. Research on these interventions has yielded positive outcomes in fracture rates. The bisphosphonates and vitamin D and calcium suppliments are the preferred therapy for prevention of osteoporotic fractures. Weight-bearing exercise and reducing home hazards have beneficial effects in reducing the incidence of falls and consequently reduce fractures. Prevention of fractures in elderly consists of therapy and prevention of osteoporosis, fall prevention, and using injury-site protection by high-risk elderly patients. Special consideration needs to be taken to reduce home hazard, and falls prevention education can be recommended to the elderly with history of fall or mobility limitations. Future research to prevent fractures in elderly population should not only concentrate on improving bone density and strength but also need to be focused on falls reduction strategies. PMID- 30283612 TI - Dietary Supplements and Cardiovascular Diseases. AB - The market of nutritional supplements is expected to expand over 6%/year through 2018 due to growing interest in personal health, aging population, and promising personalized care products. The most used dietary supplements are fish oil, multivitamins, Vitamin D, and coenzyme Q10 (CoQ10) in this order, while probiotics is the fastest growing supplement. In the U.S., over 68% of the population use dietary supplements regularly. On the other hand, in the developed countries, cardiovascular diseases (CVDs) are the main cause of death and morbidity from the 1900s. The effects of most dietary supplements on cardiovascular risk and CVD have been studied for a long time. However, despite several studies explored the association of the various supplements to the cardiovascular risk, there is still a lack of consensus. Multivitamin supplementation has been advocated to reduce cardiovascular events; Vitamin D levels have been associated with the occurrence of coronary artery disease, heart failure, and atrial fibrillation; CoQ10 deficiency has been associated with myocardial dysfunction and with statin myopathy; probiotoics has been suggested to lower both blood pressure and circulating lipids. However, the study of the effects of dietary supplementations is not straightforward, since people assuming dietary supplements generally have a healthier diet and lifestyle, and randomized studies are rarely performed. In this review, we will summarize the findings linking dietary supplements to CVD with a special focus on novel insights. PMID- 30283613 TI - Interventions for Physician Burnout: A Systematic Review of Systematic Reviews. AB - Occupational burnout is a common syndrome among physicians, and several individual-directed and organization-directed interventions have been implemented to reduce it. Until now, several review studies have tried to identify and introduce the most appropriate interventions. The aim of this article was to systematically review systematic review studies of interventions for physician burnout to evaluate and summarize their results, and ultimately guide researchers to select appropriate interventions. A search was conducted to find review studies and systematic reviews in Cochrane Database of Systematic Reviews, Medline, Google Scholar, PubMed, and PsycINFO. Two reviewers independently selected and evaluated the studies based on inclusion criteria. Four of seven obtained review studies and systematic reviews met the inclusion criteria. These studies have reviewed individual-directed and organization-directed interventions intended to reduce burnout among medical students, interns, physicians, residents, and fellows. Various studies of the effectiveness of individual- and organization-directed interventions have obtained different results. This research has shown that reaching conclusions about effective interventions (individual- or organization-directed) for physician burnout is not easy and that a number of mediating or moderating variables probably influence the effectiveness of these interventions. Therefore, it is necessary to understand approaches and interventions for the prevention or reduction of physician burnout to fill the gaps in research. In addition, review studies are required to be more precise in choosing their criteria to find more accurate results. PMID- 30283611 TI - Ocular Parasitosis Caused by Protozoan Infection during Travel: Focus on Prevention and Treatment. AB - International travel is rising quickly worldwide. Many people travel to tropical and subtropical areas, where there has been increasing exposure of travelers to infectious pathogens. Ocular parasitic infections are more prevalent in these geographical areas and they can lead to morbidity and mortality, often due to late or misdiagnosis due to the unfamiliarity of health staff with these diseases. This is an up-to-date comprehensive review article that familiarizes physicians with ocular signs and symptoms, treatment, prevention, and geographic distribution of some parasites associated with travel. PMID- 30283614 TI - Effect of Coenzyme Q10 Supplementation on Serum of High Sensitivity c-reactive Protein Level in Patients with Cardiovascular Diseases: A Systematic Review and Meta-analysis of Randomized Controlled Trials. AB - : Possible effects of coenzyme Q10 (CoQ10) supplement on the serum level of high sensitivity C-reactive protein (hs-CRP) in cardiovascular diseases (CVDs) remains unclear. Objective: Therefore, this meta-analysis was conducted to investigate its effects on the serum hs-CRP level in patients with CVDs. A comprehensive search was conducted on the EMBASE, MEDLINE, and PubMed Central databases for pertinent papers in English up to November 2016. All randomized controlled trials (RCTs) that studied the effects of supplementation with CoQ10 on the serum of hs CRP level in cardiovascular patients were included. We used random-effects models (the DerSimonian-Laird method) to estimate the pooled effect of selected studies and the I2 test to assess the between-study heterogeneity. The subgroup analyses were carried out according to the baseline serum hs-CRP, quality assessment score, supplementation dosage, and duration of intervention. Of 205 studies, five trials were eligible for inclusion in this study with 159 participants in the ntervention and 143 participants in the placebo group. Results of the pooled analysis revealed that the CoQ10 supplementation had no significant effect on the serum level of hs-CRP compared with the placebo group (MD: 0.120; 95% = -0.944, 1.185; P = 0.825). Moreover, the subgroup analyses showed the baseline serum hs CRP, quality assessment score, and duration of intervention can be sources of heterogeneity. The results of this study demonstrated that the beneficial effect of CoQ10 supplementation for patients with CVDs is observed in those who received this supplement for more than 12 weeks and with the baseline serum hs-CRP >3 mg/L. PMID- 30283616 TI - Bacteremic meningitis due to Pasteurella multocida resistant to first line antibiotic therapy. AB - Pasteurella species reside in the gastrointestinal tract of many animals, especially in pets such as cats or dogs. Zoonotic transmission of Pasteurella to human is documented. We describe a case of meningitis in a 66-year-old woman with positive blood culture for Pasteurella multocida. Meningitis caused by zoonosis agents is a rare event, but it should be suspected in patients that have recreational or professional exposure to animals. In this case, not only the etiologic agent was rare, but the microorganism was also resistant to firstline antibiotic drugs. PMID- 30283615 TI - Comparative Effectiveness of Prophylactic Therapies for Necrotizing Enterocolitis in Preterm Infants: Protocol for a Network Meta-analysis of Randomized Trials. AB - : Necrotizing enterocolitis (NEC) is a common and devastating disease with high morbidity and mortality in premature infants. Current literature on the prevention of NEC has limitations including lack of direct and indirect comparisons of available therapies. We will search MEDLINE, EMBASE, Science Citation Index Expanded, Social Sciences Citation Index, CINAHL, Scopus, ProQuest Dissertations and Theses database, and grey literature sources to identify eligible trials evaluating NEC preventive therapies. Eligible studies will (1) enroll preterm (gestational age <37 weeks) and/or low birth weight (birth weight <2500 g) infants, (2) randomize infants to any preventive intervention or a placebo, or alternative active or nonactive intervention. Our outcomes of interest are severe NEC (stage II or more, based on Bell's criteria), all-cause mortality, NEC-related mortality, late-onset sepsis, duration of hospitalization, weight gain, time to establish full enteral feeds, and treatment-related adverse events. Two reviewers will independently screen trials for eligibility, assess risk of bias, and extract data. All discrepancies will be resolved by discussion. We will specify a priori explanations for heterogeneity between studies. For available comparisons between treatment and no treatment, and direct comparisons of treatments, we will conduct conventional meta-analysis using a random effects model. We will conduct a network meta-analysis using a random effects model within the Bayesian framework using Markov chain Monte Carlo methods to assess relative effects of eligible interventions. We will assess the certainty in direct, indirect, and network estimates using the Grading of Recommendations Assessment, Development and Evaluation approach. Ethics and Dissemination: We will disseminate our findings through a peer-reviewed publication and conference presentations. PMID- 30283617 TI - Acquired hemophilia A developing cerebral infarction 36 days after the frequent administration of bypass hemostatic agents. AB - A 74-years-old male who was a smoker and received treatment for hypertension, dyslipidemia, peripheral arterial disease and idiopathic interstitial pneumonia complained of subcutaneous hemorrhage of the right lower thigh. Marked anemia (hemoglobin 5.5 g/dL) and prolonged activated partial thromboplastin time (>=130 seconds) were noted. The factor VIII activity level was reduced to 1.2%, and the factor VIII inhibitor titer was 285.3 BU/mL, a diagnosis of acquired hemophilia A (AHA) was made. Then, hematomas of 5 intra-muscles were recurred. Hemostasis became difficult despite frequent and high-dose administration of recombinant human coagulation factor VIIa (total: 18 days, 305 mg). Hemostasis was achieved by switching to activated prothrombin complex concentrate (for 3 days, 18,000 units), however, cerebral infarction occurred after 36 days. After the frequent administration of bypass hemostatic agents on elderly AHA patients with several risk factors for ischemic stroke, the risk of subsequent thrombotic events may persist for 1 month. PMID- 30283618 TI - Clinical significance of dasatinib-induced pleural effusion in patients with de novo chronic myeloid leukemia. AB - Dasatinib is currently approved for clinical use as a first-line treatment agent for newly diagnosed chronic myeloid leukemia (CML). However, only a few clinical trials have been performed to evaluate dasatinibinduced PE following first-line therapy. We investigated the incidence and clinical features of dasatinib-induced PE following first-line therapy in Japanese CML patients of real world clinical practice settings. Among 22 patients, the median age of PE-positive patients was higher than that of PE-negative patients. Major molecular response was achieved in 75% of PE-positive patients and 50% of PE-negative patients. Most patients developed PE more than 1 year after treatment. Appearance of PE is associated with better clinical response during dasatinib treatment, however it is developed at any time. Elderly and high-risk patients tend to develop PE. The clinical features of dasatinib-induced PE following first-line therapy might be late onset and might not immediately follow the increasing of large granular lymphocyte. PMID- 30283619 TI - Long-term complete remission of early hematological relapse after discontinuation of immunosuppressants following allogeneic transplantation for Sezary syndrome. AB - Sezary syndrome (SS) is a leukemic form of cutaneous T-cell lymphoma and is chemo resistant. Allogeneic hematopoietic stem cell transplantation is a promising therapy for SS; however, relapse is common. Therapeutic options after relapse have not been established. We managed an SS patient with hematological relapse within one month after transplantation. After discontinuation of immunosuppressants, she achieved complete remission and remained relapse-free. The chimeric analyses of Tcells showed that the full recipient type became complete donor chimera after immunological symptoms. This clinical course suggested that discontinuation of immunosuppressants may result in a graftversus- tumor effect, leading to the eradication of lymphoma cells. PMID- 30283620 TI - The role of red cell distribution width in the differential diagnosis of iron deficiency anemia and non-transfusiondependent thalassemia patients. AB - This study aims to find the cut-off value and diagnostic accuracy of the use of RDW as initial investigation in enabling the differentiation between IDA and NTDT patients. Patients with microcytic anemia were enrolled in the training set and used to plot a receiving operating characteristics (ROC) curve to obtain the cut off value of RDW. A second set of patients were included in the validation set and used to analyze the diagnostic accuracy. We recruited 94 IDA and 64 NTDT patients into the training set. The area under the curve of the ROC in the training set was 0.803. The best cut-off value of RDW in the diagnosis of NTDT was >21.0% with a sensitivity and specificity of 81.3% and 55.3% respectively. In the validation set, there were 34 IDA and 58 NTDT patients using the cut-off value of 21.0% to validate. The sensitivity, specificity, positive predictive value and negative predictive value were 84.5%, 70.6%, 83.1% and 72.7% respectively. We can therefore conclude that RDW >21.0% is useful in differentiating between IDA and NTDT patients with high diagnostic accuracy. PMID- 30283621 TI - Myelodysplasia-related acute myeloid leukemia and acute promyelocytic leukemia: concomitant occurrence of two molecularly distinct diseases. AB - Concurrent presentation of acute promyelocytic leukemia (APL) with other hematologic diseases in the absence of previous chemotherapy or ionizing radiotherapy treatment is very rare. We present a case of simultaneous occurrence of APL with myelodysplastic syndrome (MDS)-related acute myeloid leukemia (AML). A 43-yearold female presented with 3 month of history fatigue, night sweats, chills and pancytopenia. Bone marrow aspirate and biopsy demonstrated 20% myeloid blasts with dysplastic changes admixed with abnormal promyelocytes. Cytogenetic analysis showed tetraploidy and deletion in chromosomes 5q and 7q and polymerase chain reaction showed presence of PML/RARA mRNA transcripts, confirming the presence of concurrent APL and MDS-related AML. Induction chemotherapy with cytarabine and daunorubicin was initiated along with all-trans retinoic acid. This is the first case to be reported in the literature of concurrent occurrence of APL with MDS-related AML. Treatment with 7 + 3 regimen and ATRA was successful in inducing complete remission. PMID- 30283622 TI - The progression of severe aplastic anemia to hypoplastic leukemia in a long-term observation after the administration of pegylated rHuMGDF. AB - Thrombopoietin (TPO) is a critical regulator of hematopoiesis. We previously reported that a severe aplastic anemia (SAA) who received a short-term administration of pegylated recombinant human megakaryocyte growth and development factor (rHuMGDF). A trilineage hematologic response was induced, however the patient was diagnosed with leukemia after nine years and eight months from administration of rHuMGDF. In recent reports, somatic mutations in myeloid cancer candidate genes were present in one-third of the AA. A mutant clone may be expanded by rHuMGDF in our patient. The long-term safety of patients treated with TPO and eltrombopag remains unknown. Careful observations are warranted hereafter. PMID- 30283623 TI - The Illusion of Uniformity Does Not Depend on the Primary Visual Cortex: Evidence From Sensory Adaptation. AB - Visual experience appears richly detailed despite the poor resolution of the majority of the visual field, thanks to foveal-peripheral integration. The recently described uniformity illusion (UI), wherein peripheral elements of a pattern take on the appearance of foveal elements, may shed light on this integration. We examined the basis of UI by generating adaptation to a pattern of Gabors suitable for producing UI on orientation. After removing the pattern, participants reported the tilt of a single peripheral Gabor. The tilt aftereffect followed the physical adapting orientation rather than the global orientation perceived under UI, even when the illusion had been reported for a long time. Conversely, a control experiment replacing illusory uniformity with a physically uniform Gabor pattern for the same durations did produce an aftereffect to the global orientation. Results indicate that UI is not associated with changes in sensory encoding at V1 but likely depends on higher level processes. PMID- 30283624 TI - Scientific evidence, rather than uncontrolled case studies should be the basis for patient management. PMID- 30283625 TI - Real-world incidence of patient-reported dyspnoea with ticagrelor. AB - Dyspnoea, a common and multifactorial symptom in patients with acute coronary syndrome, has been associated with lower quality of life and hospital readmission. Prescriber preference for antiplatelet therapy, the standard of care in this patient group, is shifting to ticagrelor due to mortality benefits demonstrated in trials compared with clopidogrel. In these trials, dyspnoea was more commonly reported in patients prescribed ticagrelor but the aetiology is still debated. An observational cohort study was conducted to quantify the rates and severity of dyspnoea reported in patients with acute coronary syndrome and newly prescribed ticagrelor compared with those prescribed clopidogrel. Dyspnoea was more commonly reported in patients prescribed ticagrelor at each follow up post-discharge (p = 0.016). Rates were higher than previously reported in clinical trials. In some patients, dyspnoea necessitated drug therapy change and was associated with readmission to hospital (p = 0.046). As ticagrelor is widely prescribed as a first-line antiplatelet agent for a range of patients with acute coronary syndrome, the incidence of dyspnoea in a generalized patient cohort may result in higher rates of drug discontinuation. This in turn could lead to higher rates of rehospitalisation and potential treatment failure than that reported from the controlled setting of a clinical trial. PMID- 30283626 TI - Adverse drug reaction reporting in a large tertiary hospital in Saudi Arabia: results of an incentive strategy. AB - Background: Underreporting is a common problem with spontaneous adverse drug reaction (ADR) reporting. In this study, we aim to describe the reporting of ADRs in a tertiary hospital and determine the effect of incentives to healthcare professionals on ADR reporting. Methods: In this interventional study, a time series analysis was used to determine the effect of incentives on ADR reporting in a tertiary hospital between 2015 and 2016. The incentive strategy included public commendation of health care providers and nomination for a monthly award. Results: A total of 967 ADRs were reported over a 2-year period. After the introduction of incentives in January 2016, the number of ADR reports per month increased by 40.6 (95% confidence interval: 26.1-55.1). The proportion of serious ADRs reported was significantly higher in 2016 (39/800) than 2015 (0/167) (p < 0.001). In 2016, there was a significant association between profession and serious ADR reporting (p < 0.001). A total of 14/21 ADRs (66.7%) reported by physicians in 2016 were serious compared with 20/700 (2.9%) reported by clinical pharmacists and 5/72 (6.9%) by nurses. Conclusions: ADR reporting was improved by providing incentives, including commendation and reward, to healthcare professionals. PMID- 30283627 TI - Using social media in safety signal management: is it reliable? AB - Social media use is growing globally, with a reported 3 billion active users in 2017. This medium is used increasingly in a health setting by patients (and to a limited extent, healthcare professionals) to share experiences and ask advice on medical conditions as well as pharmaceutical products. In recent years, attention has turned to this huge, generally untapped, source of potential health information as a possible tool for pharmacovigilance, and in particular signal detection. In this article we explore some of the challenges of utilizing social media for safety signal detection and look at some of the pilot studies conducted to date in order to weigh the evidence for and against the utility of social media data in safety signal detection. After doing so we can conclude that the analysis of social media datasets has demonstrated a limited contribution to the signal detection and signal management process. The data available in social media can complement blind spots in traditional pharmacovigilance datasets and provide significant value for targeted investigations and studies such as those relating to abuse, misuse, use in pregnancy, and patient sentiments. PMID- 30283628 TI - The surge in biosimilars: considerations for effective pharmacovigilance and EU regulation. AB - The development of biosimilars is growing rapidly, especially in Europe. They are a cost-effective alternative to original biological medicines and can help improve patient access to these therapies. The European Medicines Agency (EMA) has been the first to issue scientific guidelines related to regulatory requirements for the approval of biosimilars. These guidelines have been being updated in line with advances in analytical techniques and growing experience in the clinical use of these drugs. Given the complex nature of biological medicines, they pose a greater potential risk of immunogenicity than nonbiological medicines, and hence warrant special consideration. The risk management plan for biopharmaceuticals (innovator and biosimilar drugs) should be based on strengthening ongoing pharmacovigilance activities, especially in the post-approval period. This paper addresses regulatory issues related to the approval of biosimilars in Europe associated with safety considerations linked to the development and use of these medicines. We also discuss the issues of immunogenicity, interchangeability and traceability of biological medicines.

AB - Neuroendocrine tumors (NETs) are an uncommon diagnosis which often present asymptomatically or with vague symptoms. They can originate from many different organs such as the GI tract, lungs, pancreas and others. 68Gallium DOTATATE positron emission topography/computed topography has been shown to be an effective imaging modality for diagnosing NET and evaluating management options for patients. Here, we present two cases of positive findings in the distal pancreas on the DOTATATE PET/CT scans without any morphological lesion found to be NET in a healthy 48-year-old male and 68-year-old male. PMID- 30283630 TI - Adult ileocecal intussusception induced by adenomatous ileal polyp: case report and literature review. AB - Intussusception is a rare cause of bowel obstruction in adults, and has generally an organic etiology. However, adenomatous polyp of the small bowel is an uncommon etiology. Moreover, there's a great difference with childhood intussusception in its presentation, etiology and management. We describe herein a case of adult ileocecal intussusception due to an adenomatous ileal polyp with a preoperative diagnosis made on computed tomography. We performed a right hemicolectomy, without attempting to reduce the intussusception, and an end-to-end ileotransverse anastomosis. The pathological examination of the surgical specimen revealed an adenomatous polyp with a high grade dysplasia on the terminal ileum, being the cause of the ileocecal intussusception.

PMID- 30283632 TI - Elastic serum-albumin based hydrogels: mechanism of formation and application in cardiac tissue engineering. AB - Hydrogels are promising materials for mimicking the extra-cellular environment. Here, we present a simple methodology for the formation of a free-standing viscoelastic hydrogel from the abundant and low cost protein serum albumin. We show that the mechanical properties of the hydrogel exhibit a complicated behaviour as a function of the weight fraction of the protein component. We further use X-ray scattering to shed light on the mechanism of gelation from the formation of a fibrillary network at low weight fractions to interconnected aggregates at higher weight fractions. Given the match between our hydrogel elasticity and that of the myocardium, we investigated its potential for supporting cardiac cells in vitro. Interestingly, these hydrogels support the formation of several layers of myocytes and significantly promote the maintenance of a native-like gene expression profile compared to those cultured on glass. When confronted with a multicellular ventricular cell preparation, the hydrogels can support macroscopically contracting cardiac-like tissues with a distinct cell arrangement, and form mm-long vascular-like structures. We envisage that our simple approach for the formation of an elastic substrate from an abundant protein makes the hydrogel a compelling biomedical material candidate for a wide range of cell types.

AB - Recent studies suggest that environmentally induced effects on sperm phenotype can influence offspring phenotype beyond the classic Mendelian inheritance mechanism. However, establishing whether such effects are conveyed purely through ejaculates, independently of maternal environmental effects, remains a significant challenge. Here, we assess whether environmentally induced effects on sperm phenotype affects male reproductive success and offspring fitness. We experimentally manipulated the duration of sperm storage by males, and thus sperm age, in the internally fertilizing fish Poecilia reticulata. We first confirm that sperm ageing influences sperm quality and consequently males reproductive success. Specifically, we show that aged sperm exhibit impaired velocity and are competitively inferior to fresh sperm when ejaculates compete to fertilize eggs. We then used homospermic (noncompetitive) artificial insemination to inseminate females with old or fresh sperm and found that male offspring arising from fertilizations by experimentally aged sperm suffered consistently impaired sperm quality when just sexually mature (four months old) and subsequently as adults (13 months old). Although we have yet to determine whether these effects have a genetic or epigenetic basis, our analyses provide evidence that environmentally induced variation in sperm phenotype constitutes an important source of variation in male reproductive fitness that has far reaching implications for offspring fitness. PMID- 30283633 TI - The importance of clinical pharmacokinetic-pharmacodynamic studies in unraveling the determinants of early and late tuberculosis outcomes. AB - Tuberculosis remains a major infectious cause of morbidity and mortality worldwide. Current antibiotic regimens, constructed prior to the development of modern pharmacokinetic-pharmacodynamic (PK-PD) tools, are based on incomplete understanding of exposure-response relationships in drug susceptible and multidrug resistant tuberculosis. Preclinical and population PK data suggest that clinical PK-PD studies may enable therapeutic drug monitoring for some agents and revised dosing for others. Future clinical PK-PD challenges include: incorporation of PK methods to assay free concentrations for all active metabolites; selection of appropriate early outcome measures which reflect therapeutic response; elucidation of genetic contributors to interindividual PK variability; conduct of targeted studies on special populations (including children); and measurement of PK-PD parameters at the site of disease. PMID- 30283636 TI - Integrating viability and fecundity selection to illuminate the adaptive nature of genetic clines. AB - Genetically based trait variation across environmental gradients can reflect adaptation to local environments. However, natural populations that appear well adapted often exhibit directional, not stabilizing, selection on ecologically relevant traits. Temporal variation in the direction of selection could lead to stabilizing selection across multiple episodes of selection, which might be overlooked in short-term studies that evaluate relationships of traits and fitness under only one set of conditions. Furthermore, nonrandom mortality prior to trait expression can bias inferences about trait evolution if viability selection opposes fecundity selection. Here, we leveraged fitness and trait data to test whether phenotypic clines are genetically based and adaptive, whether temporal variation in climate imposes stabilizing selection, and whether viability selection acts on adult phenotypes. We monitored transplants of the subalpine perennial forb, Boechera stricta (Brassicaceae), in common gardens at two elevations over 2-3 years that differed in drought intensity. We quantified viability, and fecundity fitness components for four heritable traits: specific leaf area, integrated water-use efficiency, height at first flower, and flowering phenology. Our results indicate that genetic clines are maintained by selection, but their expression is context dependent, as they do not emerge in all environments. Moreover, selection varied spatially and temporally. Stabilizing selection was most pronounced when we integrated data across years. Finally, viability selection prior to trait expression targeted adult phenotypes (age and size at flowering). Indeed, viability selection for delayed flowering opposed fecundity selection for accelerated flowering; this result demonstrates that neglecting to account for viability selection could lead to inaccurate conclusions that populations are maladapted. Our results suggest that reconciling clinal trait variation with selection requires data collected across multiple spatial scales, time frames, and life-history stages. PMID- 30283637 TI - Linking speciation to extinction: Diversification raises contemporary extinction risk in amphibians. AB - Many of the traits associated with elevated rates of speciation, including niche specialization and having small and isolated populations, are similarly linked with an elevated risk of extinction. This suggests that rapidly speciating lineages may also be more extinction prone. Empirical tests of a speciation extinction correlation are rare because assessing paleontological extinction rates is difficult. However, the modern biodiversity crisis allows us to observe patterns of extinction in real time, and if this hypothesis is true then we would expect young clades that have recently diversified to have high contemporary extinction risk. Here, we examine evolutionary patterns of modern extinction risk across over 300 genera within one of the most threatened vertebrate classes, the Amphibia. Consistent with predictions, rapidly diversifying amphibian clades also had a greater share of threatened species. Curiously, this pattern is not reflected in other tetrapod classes and may reflect a greater propensity to speciate through peripheral isolation in amphibians, which is partly supported by a negative correlation between diversification rate and mean geographic range size. This clustered threat in rapidly diversifying amphibian genera means that protecting a small number of species can achieve large gains in preserving amphibian phylogenetic diversity. Nonindependence between speciation and extinction rates has many consequences for patterns of biodiversity and how we may choose to conserve it.

AB - Imprinted genes are peculiar in that expression of the two copies differs depending on whether the copy was maternally or paternally inherited. The discovery of this striking pattern of gene expression inspired myriad evolutionary theories, the most successful of which identify scenarios that create an asymmetry between the maternally and paternally inherited gene copies that favors silencing of one of the copies. Most notably, imprinting can evolve when gene dosage affects kin interactions (typically involving conflict) or when silencing enhances coadaptation by coordinating traits expressed by interacting kin. Although we have a well-established theory for the former process (the "Kinship Theory"), the coadaptation process has only been explored for the specific case of interactions between mothers and offspring. Here, we fill this critical gap in our understanding by developing a general "Coadaptation Theory" that explains how imprinting can evolve to coordinate interactions between all types of relatives. Using a simple model in which fitness of an individual is determined by an interaction between its own phenotype (and hence genotype) and that of its social partner(s), we find that when the relatedness of interactants differs through their maternally versus paternally inherited gene copies, then selection favors expression of the allele through which relatedness is higher. The predictions of this Coadaptation Theory potentially apply whenever a gene underlies traits that mediate the outcome of conspecific interactions, regardless of their mechanism or the type of organism, and therefore provide a potential explanation for enigmatic patterns of imprinting, including those underlying adult traits. By providing simple testable predictions that often directly contrast with those derived from alternative theories, our model should play an important role in consolidating our understanding of the evolution of imprinting across genes and species, which will ultimately provide crucial insights into imprinted gene function and dysfunction.

AB - Domesticated grain crops evolved from wild plants under human cultivation, losing natural dispersal mechanisms to become dependent upon humans, and showing changes in a suite of other traits, including increasing seed size. There is tendency for seed enlargement during domestication to be viewed as the result of deliberate selection for large seeds by early farmers. However, like some other domestication traits, large seeds may have evolved through natural selection from the activities of people as they gathered plants from the wild, or brought them into cultivation in anthropogenic settings. Alternatively, larger seeds could have arisen via pleiotropic effects or genetic linkage, without foresight from early farmers, and driven by selection that acted on other organs or favored larger plants. We have separated these unconscious selection effects on seed enlargement from those of deliberate selection, by comparing the wild and domesticated forms of vegetable crops. Vegetables are propagated by planting seeds, cuttings, or tubers, but harvested for their edible leaves, stems, or roots, so that seed size is not a direct determinant of yield. We find that landrace varieties of seven vegetable crops have seeds that are 20% to 2.5-times larger than those of their closest wild relatives. These domestication effect sizes fall completely within the equivalent range of 14% to 15.2-times for grain crops, although domestication had a significantly larger overall effect in grain than vegetable crops. Seed enlargement in vegetable crops that are propagated vegetatively must arise from natural selection for larger seeds on the occasions when plants recruit from seed and are integrated into the crop gene pool, or via a genetic link to selection for larger plants or organs. If similar mechanisms operate across all species, then unconscious selection during domestication could have exerted stronger effects on the seed size of our staple crops than previously realized. PMID- 30283641 TI - Direct estimation of the spontaneous mutation rate by short-term mutation accumulation lines in Chironomus riparius. AB - Mutations are the ultimate basis of evolution, yet their occurrence rate is known only for few species. We directly estimated the spontaneous mutation rate and the mutational spectrum in the nonbiting midge C. riparius with a new approach. Individuals from ten mutation accumulation lines over five generations were deep genome sequenced to count de novo mutations that were not present in a pool of F1 individuals, representing parental genotypes. We identified 51 new single site mutations of which 25 were insertions or deletions and 26 single nucleotide mutations. This shift in the mutational spectrum compared to other organisms was explained by the high A/T content of the species. We estimated a haploid mutation rate of 2.1 * 10-9 (95% confidence interval: 1.4 * 10-9 - 3.1 * 10-9) that is in the range of recent estimates for other insects and supports the drift barrier hypothesis. We show that accurate mutation rate estimation from a high number of observed mutations is feasible with moderate effort even for nonmodel species. PMID- 30283640 TI - A nonrandom subset of olfactory genes is associated with host preference in the fruit fly Drosophila orena. AB - Specialization onto different host plants has been hypothesized to be a major driver of diversification in insects, and traits controlling olfaction have been shown to play a fundamental role in host preferences. A diverse set of olfactory genes control olfactory traits in insects, and it remains unclear whether specialization onto different hosts is likely to involve a nonrandom subset of these genes. Here, we test the role of olfactory genes in a novel case of specialization in Drosophila orena. We report the first population-level sample of D. orena on the West African island of Bioko, since its initial collection in Cameroon in 1975, and use field experiments and behavioral assays to show that D. orena has evolved a strong preference for waterberry (Syzygium staudtii). We then show that a nonrandom subset of genes controlling olfaction--those controlling odorant-binding and chemosensory proteins--have an enriched signature of positive selection relative to the rest of the D. orena genome. By comparing signatures of positive selection on olfactory genes between D. orena and its sister species, D. erecta we show that odorant-binding and chemosensory have evidence of positive selection in both species; however, overlap in the specific genes with evidence of selection in these two classes is not greater than expected by chance. Finally, we use quantitative complementation tests to confirm a role for seven olfactory loci in D. orena's preference for waterberry fruit. Together, our results suggest that D. orena and D. erecta have specialized onto different host plants through convergent evolution at the level of olfactory gene family, but not at specific olfactory genes. PMID- 30283642 TI - A genomic footprint of hybrid zone movement in crested newts. AB - Speciation typically involves a stage in which species can still exchange genetic material. Interspecific gene flow is facilitated by the hybrid zones that such species establish upon secondary contact. If one member of a hybridizing species pair displaces the other, their hybrid zone would move across the landscape. Although theory predicts that moving hybrid zones quickly stagnate, hybrid zones tracked over one or a few decades do not always follow such a limitation. This suggests that hybrid zones have the potential to traverse considerable distances over extended periods of time. When hybrid zones move, introgression is predicted to result in biased gene flow of selectively neutral alleles, from the receding species into the advancing species. We test for such a genomic footprint of hybrid zone movement in a pair of crested newt species (genus Triturus) for which we have a priori support for westward hybrid zone movement. We perform a multilocus phylogeographical survey and conduct Bayesian clustering analysis, estimation of ancestry and heterozygosity, and geographical cline analysis. In a 600 km wide area east of the present day hybrid zone a genomic footprint constitutes empirical evidence consistent with westward hybrid zone movement. The crested newt case suggests that hybrid zone movement can occur over an extensive span of time and space. Inferring hybrid zone movement provides fundamental insight into historical biogeography and the speciation process, and we anticipate that hybrid zones will prove to be far more mobile than currently appreciated. PMID- 30283643 TI - Experimental evolution reveals that sperm competition intensity selects for longer, more costly sperm. AB - It is the differences between sperm and eggs that fundamentally underpin the differences between the sexes within reproduction. For males, it is theorized that widespread sperm competition leads to selection for investment in sperm numbers, achieved by minimizing sperm size within limited resources for spermatogenesis in the testis. Here, we empirically examine how sperm competition shapes sperm size, after more than 77 generations of experimental selection of replicate lines under either high or low sperm competition intensities in the promiscuous flour beetle Tribolium castaneum. After this experimental evolution, populations had diverged significantly in their sperm competitiveness, with sperm in ejaculates from males evolving under high sperm competition intensities gaining 20% greater paternity than sperm in ejaculates from males that had evolved under low sperm competition intensity. Males did not change their relative investment into sperm production following this experimental evolution, showing no difference in testis sizes between high and low intensity regimes. However, the more competitive males from high sperm competition intensity regimes had evolved significantly longer sperm and, across six independently selected lines, there was a significant association between the degree of divergence in sperm length and average sperm competitiveness. To determine whether such sperm elongation is costly, we used dietary restriction experiments, and revealed that protein-restricted males produced significantly shorter sperm. Our findings therefore demonstrate that sperm competition intensity can exert positive directional selection on sperm size, despite this being a costly reproductive trait. PMID- 30283644 TI - No evidence that kin selection increases the honesty of begging signals in birds. AB - Providing plausible mechanisms to explain variation in the honesty of information communicated through offspring begging signals is fundamental to our understanding of parent-offspring conflict and the evolution of family life. A recently published research article used comparative analyses to investigate two long-standing hypotheses that may explain the evolution of begging behavior. The results suggested that direct competition between offspring for parental resources decreases begging honesty, whereas indirect, kin-selected benefits gained through saving parental resources for the production of future siblings increase begging honesty. However, we feel that evidence for a role of kin selection in this context is still missing. We present a combination of arguments and empirical tests to outline alternative sources of interspecific variation in offspring begging levels and discuss avenues for further research that can bring us closer to a complete understanding of the evolution of offspring signaling. PMID- 30283646 TI - Genetic differences between willow warbler migratory phenotypes are few and cluster in large haplotype blocks. AB - It is well established that differences in migratory behavior between populations of songbirds have a genetic basis but the actual genes underlying these traits remains largely unknown. In an attempt to identify such candidate genes we de novo assembled the genome of the willow warbler Phylloscopus trochilus, and used whole-genome resequencing and a SNP array to associate genomic variation with migratory phenotypes across two migratory divides around the Baltic Sea that separate SW migrating P. t. trochilus wintering in western Africa and SSE migrating P. t. acredula wintering in eastern and southern Africa. We found that the genomes of the two migratory phenotypes lack clear differences except for three highly differentiated regions located on chromosomes 1, 3, and 5 (containing 146, 135, and 53 genes, respectively). Within each migratory phenotype we found virtually no differences in allele frequencies for thousands of SNPs, even when comparing geographically distant populations breeding in Scandinavia and Far East Russia (>6000 km). In each of the three differentiated regions, multidimensional scaling-based clustering of SNP genotypes from more than 1100 individuals demonstrates the presence of distinct haplotype clusters that are associated with each migratory phenotype. In turn, this suggests that recombination is absent or rare between haplotypes, which could be explained by inversion polymorphisms. Whereas SNP alleles on chromosome 3 correlate with breeding altitude and latitude, the allele distribution within the regions on chromosomes 1 and 5 perfectly matches the geographical distribution of the migratory phenotypes. The most differentiated 10 kb windows and missense mutations within these differentiated regions are associated with genes involved in fatty acid synthesis, possibly representing physiological adaptations to the different migratory strategies. The ~200 genes in these regions, of which several lack described function, will direct future experimental and comparative studies in the search for genes that underlie important migratory traits. PMID- 30283645 TI - No evidence for maintenance of a sympatric Heliconius species barrier by chromosomal inversions. AB - Mechanisms that suppress recombination are known to help maintain species barriers by preventing the breakup of coadapted gene combinations. The sympatric butterfly species Heliconius melpomene and Heliconius cydno are separated by many strong barriers, but the species still hybridize infrequently in the wild, and around 40% of the genome is influenced by introgression. We tested the hypothesis that genetic barriers between the species are maintained by inversions or other mechanisms that reduce between-species recombination rate. We constructed fine scale recombination maps for Panamanian populations of both species and their hybrids to directly measure recombination rate within and between species, and generated long sequence reads to detect inversions. We find no evidence for a systematic reduction in recombination rates in F1 hybrids, and also no evidence for inversions longer than 50 kb that might be involved in generating or maintaining species barriers. This suggests that mechanisms leading to global or local reduction in recombination do not play a significant role in the maintenance of species barriers between H. melpomene and H. cydno. PMID- 30283647 TI - Heterogeneous gene duplications can be adaptive because they permanently associate overdominant alleles. AB - Gene duplications are widespread in genomes, but their role in contemporary adaptation is not fully understood. Although mostly deleterious, homogeneous duplications that associate identical repeats of a locus often increase the quantity of protein produced, which can be selected in certain environments. However, another type exists: heterogeneous gene duplications, which permanently associate two (or more) alleles of a single locus on the same chromosome. They are far less studied, as only few examples of contemporary heterogeneous duplications are known. Haldane proposed in 1954 that they could be adaptive in situations of heterozygote advantage, or overdominance, but this hypothesis was never tested. To assess its validity, we took advantage of the well-known model of insecticide resistance in mosquitoes. We used experimental evolution to estimate the fitnesses associated with homozygous and heterozygous genotypes in different selection regimes. It first showed that balanced antagonist selective pressures frequently induce overdominance, generating stable polymorphic equilibriums. The frequency of equilibrium moreover depends on the magnitude of two antagonistic selective pressures, the survival advantage conferred by the resistant allele versus the selective costs it induces. We then showed that heterogeneous duplications are selected over single-copy alleles in such contexts. They allow the fixation of the heterozygote phenotype, providing an alternative and stable intermediate fitness trade-off. By allowing the rapid fixation of divergent alleles, this immediate advantage could contribute to the rarity of overdominance. More importantly, it also creates new material for long term genetic innovation, making a crucial but underestimated contribution to the evolution of new genes and gene families. PMID- 30283648 TI - The genomic basis of cichlid fish adaptation within the deepwater "twilight zone" of Lake Malawi. AB - Deepwater environments are characterized by low levels of available light at narrow spectra, great hydrostatic pressure, and low levels of dissolved oxygen conditions predicted to exert highly specific selection pressures. In Lake Malawi over 800 cichlid species have evolved, and this adaptive radiation extends into the "twilight zone" below 50 m. We use population-level RAD-seq data to investigate whether four endemic deepwater species (Diplotaxodon spp.) have experienced divergent selection within this environment. We identify candidate genes including regulators of photoreceptor function, photopigments, lens morphology, and haemoglobin, many not previously implicated in cichlid adaptive radiations. Colocalization of functionally linked genes suggests coadapted "supergene" complexes. Comparisons of Diplotaxodon to the broader Lake Malawi radiation using genome resequencing data revealed functional substitutions and signatures of positive selection in candidate genes. Our data provide unique insights into genomic adaptation within deepwater habitats, and suggest genome level specialization for life at depth as an important process in cichlid radiation. PMID- 30283649 TI - Fire ant social chromosomes: Differences in number, sequence and expression of odorant binding proteins. AB - Variation in social behavior is common yet our knowledge of the mechanisms underpinning its evolution is limited. The fire ant Solenopsis invicta provides a textbook example of a Mendelian element controlling social organization: alternate alleles of a genetic element first identified as encoding an odorant binding protein (OBP) named Gp-9 determine whether a colony accepts one or multiple queens. The potential roles of such a protein in perceiving olfactory cues and evidence of positive selection on its amino acid sequence made it an appealing candidate gene. However, we recently showed that recombination is suppressed between Gp-9 and hundreds of other genes as part of a >19 Mb supergene like region carried by a pair of social chromosomes. This finding raises the need to reassess the potential role of Gp-9. We identify 23 OBPs in the fire ant genome assembly, including nine located in the region of suppressed recombination with Gp-9. For six of these, the alleles carried by the two variants of the supergene-like region differ in protein-coding sequence and thus likely in function, with Gp-9 showing the strongest evidence of positive selection. We identify an additional OBP specific to the Sb variant of the region. Finally, we find that 14 OBPs are differentially expressed between single- and multiple-queen colonies. These results are consistent with multiple OBPs playing a role in determining social structure. PMID- 30283651 TI - Divergent artificial selection for female reproductive investment has a sexually concordant effect on male reproductive success. AB - Depending on the genetic architecture of male and female fitness, sex-specific selection can have negative, positive, or neutral consequences for the opposite sex. Theory predicts that conflict between male and female function may drive the breakdown of intrasexual genetic correlations, allowing sexual dimorphism in sexually antagonistic traits. Reproductive traits are the epitome of this, showing highly differentiated proximate functions between the sexes. Here we use divergent artificial selection lines for female reproductive investment to test how female-specific selection on a sex-limited trait affects male reproductive success in a precocial bird, the Japanese quail (Coturnix japonica). We demonstrate that selection for increased egg investment in females positively affects male reproductive success both in competitive and non-competitive mating situations. This increased reproductive success was linked to a relatively larger left testis in males originating from lines selected for high female reproductive investment. Given that female quail have functional gonads only on their left side, this correlated response indicates that selection has acted on the shared developmental basis of male and female gonads. Our study thereby provides evidence for a positive genetic correlation between key reproductive traits in males and females despite a high degree of sexual dimorphism, and suggests that, in this system, selection on reproductive function is sexually concordant. PMID- 30283650 TI - Friendly foes: The evolution of host protection by a parasite. AB - Hosts are often infected by multiple parasite species, yet the ecological and evolutionary implications of the interactions between hosts and coinfecting parasites are largely unknown. Most theoretical models of evolution among coinfecting parasites focus on the evolution of virulence, but parasites may also evolve to protect their hosts by reducing susceptibility (i.e., conferring resistance) to other parasites or reducing the virulence of coinfecting parasites (i.e., conferring tolerance). Here, we analyze the eco-evolutionary dynamics of parasite-conferred resistance and tolerance using coinfection models. We show that both parasite-conferred resistance and tolerance can evolve for a wide range of underlying trade-offs. The shape and strength of the trade-off qualitatively affects the outcome causing shifts between the minimisation or maximization of protection, intermediate stable strategies, evolutionary branching, and bistability. Furthermore, we find that a protected dimorphism can readily evolve for parasite-conferred resistance, but find no evidence of evolutionary branching for parasite-conferred tolerance, in general agreement with previous work on host evolution. These results provide novel insights into the evolution of parasite conferred resistance and tolerance, and suggest clues to the underlying trade offs in recent experimental work on microbe-mediated protection. More generally, our results highlight the context dependence of host-parasite relationships in complex communities. PMID- 30283652 TI - Feminizing Wolbachia endosymbiont disrupts maternal sex chromosome inheritance in a butterfly species. AB - Wolbachia is a maternally inherited ubiquitous endosymbiotic bacterium of arthropods that displays a diverse repertoire of host reproductive manipulations. For the first time, we demonstrate that Wolbachia manipulates sex chromosome inheritance in a sexually reproducing insect. Eurema mandarina butterfly females on Tanegashima Island, Japan, are infected with the wFem Wolbachia strain and produce all-female offspring, while antibiotic treatment results in male offspring. Fluorescence in situ hybridization (FISH) revealed that wFem-positive and wFem-negative females have Z0 and WZ sex chromosome sets, respectively, demonstrating the predicted absence of the W chromosome in wFem-infected lineages. Genomic quantitative polymerase chain reaction (qPCR) analysis showed that wFem-positive females lay only Z0 eggs that carry a paternal Z, whereas females from lineages that are naturally wFem-negative lay both WZ and ZZ eggs. In contrast, antibiotic treatment of adult wFem females resulted in the production of Z0 and ZZ eggs, suggesting that this Wolbachia strain can disrupt the maternal inheritance of Z chromosomes. Moreover, most male offspring produced by antibiotic-treated wFem females had a ZZ karyotype, implying reduced survival of Z0 individuals in the absence of feminizing effects of Wolbachia. Antibiotic treatment of wFem-infected larvae induced male-specific splicing of the doublesex (dsx) gene transcript, causing an intersex phenotype. Thus, the absence of the female-determining W chromosome in Z0 individuals is functionally compensated by Wolbachia-mediated conversion of sex determination. We discuss how Wolbachia may manipulate the host chromosome inheritance and that Wolbachia may have acquired this coordinated dual mode of reproductive manipulation first by the evolution of female-determining function and then cytoplasmically induced disruption of sex chromosome inheritance. PMID- 30283653 TI - Environmental variation causes different (co) evolutionary routes to the same adaptive destination across parasite populations. AB - Epidemics are engines for host-parasite coevolution, where parasite adaptation to hosts drives reciprocal adaptation in host populations. A key challenge is to understand whether parasite adaptation and any underlying evolution and coevolution is repeatable across ecologically realistic populations that experience different environmental conditions, or if each population follows a completely unique evolutionary path. We established twenty replicate pond populations comprising an identical suite of genotypes of crustacean host, Daphnia magna, and inoculum of their parasite, Pasteuria ramosa. Using a time shift experiment, we compared parasite infection traits before and after epidemics and linked patterns of parasite evolution with shifts in host genotype frequencies. Parasite adaptation to the sympatric suite of host genotypes came at a cost of poorer performance on foreign genotypes across populations and environments. However, this consistent pattern of parasite adaptation was driven by different types of frequency-dependent selection that was contingent on an ecologically relevant environmental treatment (whether or not there was physical mixing of water within ponds). In unmixed ponds, large epidemics drove rapid and strong host-parasite coevolution. In mixed ponds, epidemics were smaller and host evolution was driven mainly by the mixing treatment itself; here, host evolution and parasite evolution were clear, but coevolution was absent. Population mixing breaks an otherwise robust coevolutionary cycle. These findings advance our understanding of the repeatability of (co)evolution across noisy, ecologically realistic populations. PMID- 30283655 TI - Real-time social selection maintains honesty of a dynamic visual signal in cooperative fish. AB - Our understanding of animal communication has been largely driven by advances in theory since empirical evidence has been difficult to obtain. Costly signaling theory became the dominant paradigm explaining the evolution of honest signals, according to which communication reliability relies on differential costs imposed on signalers to distinguish animals of different quality. On the other hand, mathematical models disagree on the source of costs at the communication equilibrium. Here, we present an empirical framework to study the evolution of honest signals that generates predictions on the form, function, and sources of reliability of visual signals. We test these predictions on the facial color patterns of the cooperatively breeding Princess of Burundi cichlid, Neolamprologus brichardi. Using theoretical visual models and behavioral experiments we show that these patterns possess stable chromatic properties for efficient transmission in the aquatic environment, while dynamic changes in signal luminance are used by the fish to communicate switches in aggressive intent. By manipulating signal into out-of-equilibrium expression and simulating a cheater invasion, we demonstrate that social costs (receiver retaliation) promote the honesty of this dynamic conventional signal. By directly probing the sender of a signal in real time, social selection is likely to be the mechanism of choice shaping the evolution of inexpensive, yet reliable context-dependent social signals in general. PMID- 30283654 TI - Inconsistent reproductive isolation revealed by interactions between Catostomus fish species. AB - Interactions between species are central to evolution and ecology, but we do not know enough about how outcomes of interactions between species vary across geographic locations, in heterogeneous environments, or over time. Ecological dimensions of interactions between species are known to vary, but evolutionary interactions such as the establishment and maintenance of reproductive isolation are often assumed to be consistent across instances of an interaction between species. Hybridization among Catostomus fish species occurs over a large and heterogeneous geographic area and across taxa with distinct evolutionary histories, which allows us to assess consistency in species interactions. We analyzed hybridization among six Catostomus species across the Upper Colorado River basin (US mountain west) and found extreme variation in hybridization across locations. Different hybrid crosses were present in different locations, despite similar species assemblages. Within hybrid crosses, hybridization varied from only first generation hybrids to extensive hybridization with backcrossing. Variation in hybridization outcomes might result from uneven fitness of hybrids across locations, polymorphism in genetic incompatibilities, chance, unidentified historical contingencies, or some combination thereof. Our results suggest caution in assuming that one or a few instances of hybridization represent all interactions between the focal species, as species interactions vary substantially across locations. PMID- 30283656 TI - Single-gene speciation: Mating and gene flow between mirror-image snails. AB - Variation in the shell coiling, or chirality, of land snails provides an opportunity to investigate the potential for "single-gene" speciation, because mating between individuals of opposite chirality is believed not possible if the snails mate in a face-to-face position. However, the evidence in support of single-gene speciation is sparse, mostly based upon single-gene mitochondrial studies and patterns of chiral variation between species. Previously, we used a theoretical model to show that as the chiral phenotype of offspring is determined by the maternal genotype, occasional chiral reversals may take place and enable gene flow between mirror image morphs, preventing speciation. Here, we show empirically that there is recent or ongoing gene flow between the different chiral types of Japanese Euhadra species. We also report evidence of mating between mirror-image morphs, directly showing the potential for gene flow. Thus, theoretical models are suggestive of gene flow between oppositely coiled snails, and our empirical study shows that they can mate and that there is gene flow in Euhadra. More than a single gene is required before chiral variation in shell coiling can be considered to have created a new species. PMID- 30283657 TI - Mitogenome evolution in the last surviving woolly mammoth population reveals neutral and functional consequences of small population size. AB - The onset of the Holocene was associated with a global temperature increase, which led to a rise in sea levels and isolation of the last surviving population of woolly mammoths on Wrangel Island. Understanding what happened with the population's genetic diversity at the time of the isolation and during the ensuing 6000 years can help clarify the effects of bottlenecks and subsequent limited population sizes in species approaching extinction. Previous genetic studies have highlighted questions about how the Holocene Wrangel population was established and how the isolation event affected genetic diversity. Here, we generated high-quality mitogenomes from 21 radiocarbon-dated woolly mammoths to compare the ancestral large and genetically diverse Late Pleistocene Siberian population and the small Holocene Wrangel population. Our results indicate that mitogenome diversity was reduced to one single haplotype at the time of the isolation, and thus that the Holocene Wrangel Island population was established by a single maternal lineage. Moreover, we show that the ensuing small effective population size coincided with fixation of a nonsynonymous mutation, and a comparative analysis of mutation rates suggests that the evolutionary rate was accelerated in the Holocene population. These results suggest that isolation on Wrangel Island led to an increase in the frequency of deleterious genetic variation, and thus are consistent with the hypothesis that strong genetic drift in small populations leads to purifying selection being less effective in removing deleterious mutations. PMID- 30283658 TI - Evolution and comparative ecology of parthenogenesis in haplodiploid arthropods. AB - Changes from sexual reproduction to female-producing parthenogenesis (thelytoky) have great evolutionary and ecological consequences, but how many times parthenogenesis evolved in different animal taxa is unknown. We present the first exhaustive database covering 765 cases of parthenogenesis in haplodiploid (arrhenotokous) arthropods, and estimate frequencies of parthenogenesis in different taxonomic groups. We show that the frequency of parthenogenetic lineages extensively varies among groups (0-38% among genera), that many species have both sexual and parthenogenetic lineages and that polyploidy is very rare. Parthenogens are characterized by broad ecological niches: parasitoid and phytophagous parthenogenetic species consistently use more host species, and have larger, polewards extended geographic distributions than their sexual relatives. These differences did not solely evolve after the transition to parthenogenesis. Extant parthenogens often derive from sexual ancestors with relatively broad ecological niches and distributions. As these ecological attributes are associated with large population sizes, our results strongly suggests that transitions to parthenogenesis are more frequent in large sexual populations and/or that the risk of extinction of parthenogens with large population sizes is reduced. The species database presented here provides insights into the maintenance of sex and parthenogenesis in natural populations that are not taxon specific and opens perspectives for future comparative studies. PMID- 30283660 TI - How should we interpret estimates of individual repeatability? AB - Individual repeatability (R), defined as the proportion of observed variance attributable to among-individual differences, is a widely used summary statistic in evolutionarily motivated studies of morphology, life history, physiology and, especially, behaviour. Although statistical methods to estimate R are well known and widely available, there is a growing tendency for researchers to interpret R in ways that are subtly, but importantly, different. Some view R as a property of a dataset and a statistic to be interpreted agnostically with respect to mechanism. Others wish to isolate the contributions of 'intrinsic' and/or 'permanent' individual differences, and draw a distinction between true (intrinsic) and pseudo-repeatability arising from uncontrolled extrinsic effects. This latter view proposes a narrower, more mechanistic interpretation, than the traditional concept of repeatability, but perhaps one that allows stronger evolutionary inference as a consequence (provided analytical pitfalls are successfully avoided). Neither perspective is incorrect, but if we are to avoid confusion and fruitless debate, there is a need for researchers to recognise this dichotomy, and to ensure clarity in relation to how, and why, a particular estimate of R is appropriate in any case. PMID- 30283659 TI - Egg chemoattractants moderate intraspecific sperm competition. AB - Interactions among eggs and sperm are often assumed to generate intraspecific variation in reproductive fitness, but the specific gamete-level mechanisms underlying competitive fertilization success remain elusive in most species. Sperm chemotaxis-the attraction of sperm by egg-derived chemicals-is a ubiquitous form of gamete signaling, occurring throughout the animal and plant kingdoms. The chemical cues released by eggs are known to act at the interspecific level (e.g., facilitating species recognition), but recent studies have suggested that they could have roles at the intraspecific level by moderating sperm competition. Here, we exploit the experimental tractability of a broadcast spawning marine invertebrate to test this putative mechanism of gamete-level sexual selection. We use a fluorescently labeled mitochondrial dye in mussels to track the real-time success of sperm as they compete to fertilize eggs, and provide the first direct evidence in any species that competitive fertilization success is moderated by differential sperm chemotaxis. Furthermore, our data are consistent with the idea that egg chemoattractants selectively attract ejaculates from genetically compatible males, based on relationships inferred from both nuclear and mitochondrial genetic markers. These findings for a species that exhibits the ancestral reproductive strategy of broadcast spawning have important implications for the numerous species that also rely on egg chemoattractants to attract sperm, including humans, and have potentially important implications for our understanding of the evolutionary cascade of sexual selection. PMID- 30283661 TI - Ancient genomic variation underlies repeated ecological adaptation in young stickleback populations. AB - Adaptation in the wild often involves standing genetic variation (SGV), which allows rapid responses to selection on ecological timescales. However, we still know little about how the evolutionary histories and genomic distributions of SGV influence local adaptation in natural populations. Here, we address this knowledge gap using the threespine stickleback fish (Gasterosteus aculeatus) as a model. We extend restriction site-associated DNA sequencing (RAD-seq) to produce phased haplotypes approaching 700 base pairs (bp) in length at each of over 50,000 loci across the stickleback genome. Parallel adaptation in two geographically isolated freshwater pond populations consistently involved fixation of haplotypes that are identical-by-descent. In these same genomic regions, sequence divergence between marine and freshwater stickleback, as measured by dXY , reaches tenfold higher than background levels and genomic variation is structured into distinct marine and freshwater haplogroups. By combining this dataset with a de novo genome assembly of a related species, the ninespine stickleback (Pungitius pungitius), we find that this habitat-associated divergent variation averages six million years old, nearly twice the genome-wide average. The genomic variation that is involved in recent and rapid local adaptation in stickleback has therefore been evolving throughout the 15-million year history since the two species lineages split. This long history of genomic divergence has maintained large genomic regions of ancient ancestry that include multiple chromosomal inversions and extensive linked variation. These discoveries of ancient genetic variation spread broadly across the genome in stickleback demonstrate how selection on ecological timescales is a result of genome evolution over geological timescales, and vice versa. PMID- 30283663 TI - Sexual competition and the evolution of condition-dependent ageing. AB - Increased individual resources (condition) can be correlated with either increased or decreased longevity. While variation in resource acquisition and allocation can account for some of this variation, the general conditions that select for either pattern remain unclear. Previous models suggest that nonlinearity of payoffs from investment in reproduction (e.g., male secondary sexual traits) can select for high-condition individuals that sacrifice longevity to increase reproductive opportunity. However, it remains unclear what mating systems or patterns of sexual competition might select for such life-history strategies. We used a model of condition-dependent investment to explore how expected payoffs from increased expression of secondary sexual traits affect optimal investment in lifespan. We find that nonlinearity of these payoffs results in a negative relationship between condition and lifespan under two general conditions: first, when there are accelerating marginal benefits from increasing investment; second, when individuals that invest minimally in secondary sexual trait expression can still achieve matings. In the second scenario, the negative relationship occurs due to selection on low-condition individuals to extend lifespan at the cost of secondary sexual trait expression. Our findings clarify the potential role of sexual selection in shaping patterns of condition-dependent ageing, and highlight the importance of considering the strategies of both low- and high-condition individuals when investigating patterns of condition-dependent ageing. PMID- 30283662 TI - Genomic associations with bill length and disease reveal drift and selection across island bird populations. AB - Island species provide excellent models for investigating how selection and drift operate in wild populations, and for determining how these processes act to influence local adaptation and speciation. Here, we examine the role of selection and drift in shaping genomic and phenotypic variation across recently separated populations of Berthelot's pipit (Anthus berthelotii), a passerine bird endemic to three archipelagos in the Atlantic. We first characterized genetic diversity and population structuring that supported previous inferences of a history of recent colonizations and bottlenecks. We then tested for regions of the genome associated with the ecologically important traits of bill length and malaria infection, both of which vary substantially across populations in this species. We identified a SNP associated with variation in bill length among individuals, islands, and archipelagos; patterns of variation at this SNP suggest that both phenotypic and genotypic variation in bill length is largely shaped by founder effects. Malaria was associated with SNPs near/within genes involved in the immune response, but this relationship was not consistent among archipelagos, supporting the view that disease resistance is complex and rapidly evolving. Although we found little evidence for divergent selection at candidate loci for bill length and malaria resistance, genome scan analyses pointed to several genes related to immunity and metabolism as having important roles in divergence and adaptation. Our findings highlight the utility and challenges involved with combining association mapping and population genetic analysis in nonequilibrium populations, to disentangle the effects of drift and selection on shaping genotypes and phenotypes. PMID- 30283664 TI - Male-biased gene expression resolves sexual conflict through the evolution of sex specific genetic architecture. AB - Many genes are subject to contradictory selection pressures in males and females, and balancing selection resulting from sexual conflict has the potential to substantially increase standing genetic diversity in populations and thereby act as an important force in adaptation. However, the underlying causes of sexual conflict, and the potential for resolution, remains hotly debated. Using transcriptome-resequencing data from male and female guppies, we use a novel approach, combining patterns of genetic diversity and intersexual divergence in allele frequency, to distinguish the different scenarios that give rise to sexual conflict, and how this conflict may be resolved through regulatory evolution. We show that reproductive fitness is the main source of sexual conflict, and this is resolved via the evolution of male-biased expression. Furthermore, resolution of sexual conflict produces significant differences in genetic architecture between males and females, which in turn lead to specific alleles influencing sex specific viability. Together, our findings suggest an important role for sexual conflict in shaping broad patterns of genome diversity, and show that regulatory evolution is a rapid and efficient route to the resolution of conflict. PMID- 30283665 TI - Parallel evolution of gene expression between trophic specialists despite divergent genotypes and morphologies. AB - Parallel evolution of gene expression commonly underlies convergent niche specialization, but parallel changes in expression could also underlie divergent specialization. We investigated divergence in gene expression and whole-genome genetic variation across three sympatric Cyprinodon pupfishes endemic to San Salvador Island, Bahamas. This recent radiation consists of a generalist and two derived specialists adapted to novel niches: a scale-eating and a snail-eating pupfish. We sampled total mRNA from all three species at two early developmental stages and compared gene expression with whole-genome genetic differentiation among all three species in 42 resequenced genomes. Eighty percent of genes that were differentially expressed between snail-eaters and generalists were up or down regulated in the same direction between scale-eaters and generalists; however, there were no fixed variants shared between species underlying these parallel changes in expression. Genes showing parallel evolution of expression were enriched for effects on metabolic processes, whereas genes showing divergent expression were enriched for effects on cranial skeleton development and pigment biosynthesis, reflecting the most divergent phenotypes observed between specialist species. Our findings reveal that even divergent niche specialists may exhibit convergent adaptation to higher trophic levels through shared genetic pathways. This counterintuitive result suggests that parallel evolution in gene expression can accompany divergent ecological speciation during adaptive radiation. PMID- 30283666 TI - Comparative analysis examining patterns of genomic differentiation across multiple episodes of population divergence in birds. AB - Heterogeneous patterns of genomic differentiation are commonly documented between closely related populations and there is considerable interest in identifying factors that contribute to their formation. These factors could include genomic features (e.g., areas of low recombination) that promote processes like linked selection (positive or purifying selection that affects linked neutral sites) at specific genomic regions. Examinations of repeatable patterns of differentiation across population pairs can provide insight into the role of these factors. Birds are well suited for this work, as genome structure is conserved across this group. Accordingly, we reestimated relative (FST ) and absolute (dXY ) differentiation between eight sister pairs of birds that span a broad taxonomic range using a common pipeline. Across pairs, there were modest but significant correlations in window-based estimates of differentiation (up to 3% of variation explained for FST and 26% for dXY ), supporting a role for processes at conserved genomic features in generating heterogeneous patterns of differentiation; processes specific to each episode of population divergence likely explain the remaining variation. The role genomic features play was reinforced by linear models identifying several genomic variables (e.g., gene densities) as significant predictors of FST and dXY repeatability. FST repeatability was higher among pairs that were further along the speciation continuum (i.e., more reproductively isolated) providing further insight into how genomic differentiation changes with population divergence; early stages of speciation may be dominated by positive selection that is different between pairs but becomes integrated with processes acting according to shared genomic features as speciation proceeds. PMID- 30283667 TI - Horizontal gene cluster transfer increased hallucinogenic mushroom diversity. AB - Secondary metabolites are a heterogeneous class of chemicals that often mediate interactions between species. The tryptophan-derived secondary metabolite, psilocin, is a serotonin receptor agonist that induces altered states of consciousness. A phylogenetically disjunct group of mushroom-forming fungi in the Agaricales produce the psilocin prodrug, psilocybin. Spotty phylogenetic distributions of fungal compounds are sometimes explained by horizontal transfer of metabolic gene clusters among unrelated fungi with overlapping niches. We report the discovery of a psilocybin gene cluster in three hallucinogenic mushroom genomes, and evidence for its horizontal transfer between fungal lineages. Patterns of gene distribution and transmission suggest that synthesis of psilocybin may have provided a fitness advantage in the dung and late wood decay fungal niches, which may serve as reservoirs of fungal indole-based metabolites that alter behavior of mycophagous and wood-eating invertebrates. These hallucinogenic mushroom genomes will serve as models in neurochemical ecology, advancing the (bio)prospecting and synthetic biology of novel neuropharmaceuticals. PMID- 30283669 TI - Superior stimulation of female fecundity by subordinate males provides a mechanism for telegony. AB - When females mate promiscuously, rival males compete to fertilise the ova. In theory, a male can increase his success at siring offspring by inducing the female to lay more eggs, as well as by producing more competitive sperm. Here we report that the evolutionary consequences of fecundity stimulation extend beyond rival males, by experimentally uncovering effects on offspring. With experiments on the burying beetle Nicrophorus vespilloides, we show that smaller subordinate males are better able to stimulate female fecundity than larger, dominant males. Furthermore dominant males also benefit from the greater fecundity induced by smaller males, and so gain from the female's earlier promiscuity - just as predicted by theory. By inducing females to produce more offspring on a limited resource, smaller males cause each larva to be smaller, even those they do not sire themselves. Fecundity stimulation thus promotes the non-genetic inheritance of offspring body size, and provides a mechanism for telegony. PMID- 30283668 TI - Energy demand and the context-dependent effects of genetic interactions underlying metabolism. AB - Genetic effects are often context dependent, with the same genotype differentially affecting phenotypes across environments, life stages, and sexes. We used an environmental manipulation designed to increase energy demand during development to investigate energy demand as a general physiological explanation for context-dependent effects of mutations, particularly for those mutations that affect metabolism. We found that increasing the photoperiod during which Drosophila larvae are active during development phenocopies a temperature dependent developmental delay in a mitochondrial-nuclear genotype with disrupted metabolism. This result indicates that the context-dependent fitness effects of this genotype are not specific to the effects of temperature and may generally result from variation in energy demand. The effects of this genotype also differ across life stages and between the sexes. The mitochondrial-nuclear genetic interaction disrupts metabolic rate in growing larvae, but not in adults, and compromises female, but not male, reproductive fitness. These patterns are consistent with a model where context-dependent genotype-phenotype relationships may generally arise from differences in energy demand experienced by individuals across environments, life stages, and sexes. PMID- 30283670 TI - Life-history correlations change under coinfection leading to higher pathogen load. AB - The ability of a parasite strain to establish and grow on its host may be drastically altered by simultaneous infection by other parasite strains. However, we still lack an understanding of how life-history allocations may change under coinfection, although life-history correlations are a critical mechanism restricting the evolutionary potential and epidemiological dynamics of pathogens. Here, we study how life-history stages and their correlations change in the obligate fungal pathogen Podosphaera plantaginis under single infection and coinfection scenarios. We find increased pathogen loads under coinfection, but this is not explained by an enhanced performance at any of the life-history stages that constitute infections. Instead, we show that under coinfection the correlation between timing of sporulation and final pathogen load becomes positive. The changes in pathogen life-history allocations leading to more severe infections under coinfection can have far-reaching epidemiological consequences, as well as implication for our understanding of the evolution of virulence. PMID- 30283671 TI - The emergence, maintenance, and demise of diversity in a spatially variable antibiotic regime. AB - Antimicrobial resistance (AMR) is a growing global threat that, in the absence of new antibiotics, requires effective management of existing drugs. Here, we use experimental evolution of the opportunistic human pathogen Pseudomonas aeruginosa to explore how changing patterns of drug delivery modulates the spread of resistance in a population. Resistance evolves readily under both temporal and spatial variation in drug delivery and fixes rapidly under temporal, but not spatial, variation. Resistant and sensitive genotypes coexist in spatially varying conditions due to a resistance-growth rate trade-off which, when coupled to dispersal, generates negative frequency-dependent selection and a quasi protected polymorphism. Coexistence is ultimately lost, however, because resistant types with improved growth rates in the absence of drug spread through the population. These results suggest that spatially variable drug prescriptions can delay but not prevent the spread of resistance and provide a striking example of how the emergence and eventual demise of biodiversity is underpinned by evolving fitness trade-offs. PMID- 30283672 TI - Gender equity at scientific events. AB - Although the proportion of women in science, and in evolutionary biology in particular, has substantially increased over the last century, women remain underrepresented in academia, especially at senior levels. In addition, their scientific achievements do not always receive the same level of recognition as do men's, which can be reflected in a lower relative representation of women among invited speakers at conferences or specialized courses. Using announcements sent to the EvolDir mailing list between April 2016 and September 2017, and the symposium programs of three large evolutionary biology congresses held in summer 2017, we quantified the representation of women announced as invited speakers in conferences, congress symposia, and specialized courses. We compared the proportion of invited women to a baseline estimated using membership data of the associated scientific societies, and surveyed organizers to investigate their influence and that of potential gender-ratio guidelines on the proportion of invited women. We find that the average proportion of invited women is comparable (conferences), significantly lower (specialized courses), or significantly higher (congress symposia) than the current baseline (32% women). It is positively correlated to the proportion of women among the organizers, and it is on average higher for events whose organizers considered gender when choosing speakers than for those whose organizers did not. To investigate the impact of Equal Opportunity guidelines, we then collected longitudinal data on the proportion of invited women at two series of congresses, covering the 2001-2017 period. The proportion of invited women is higher when Equal Opportunity guidelines are announced. Encouraging women to sit on organizing committees of scientific events, and the establishment of visible Equal Opportunity guidelines, thus could be ways to ensure higher number of invited female speakers in the future. Our results suggest that change, if desired, requires deliberate actions. PMID- 30283673 TI - Is there indirect selection on female extra-pair reproduction through cross-sex genetic correlations with male reproductive fitness? AB - One key hypothesis explaining the evolution and persistence of polyandry, and resulting female extra-pair reproduction in socially monogamous systems, is that female propensity for extra-pair reproduction is positively genetically correlated with male reproductive fitness and consequently experiences positive cross-sex indirect selection. However, key genetic correlations have rarely been estimated, especially in free-living populations experiencing natural (co)variation in reproductive strategies and fitness. We used long-term life history and pedigree data from song sparrows (Melospiza melodia) to estimate the cross-sex genetic correlation between female propensity for extra-pair reproduction and adult male lifetime reproductive success, and thereby test a key hypothesis regarding mating system evolution. There was substantial additive genetic variance in both traits, providing substantial potential for indirect selection on female reproductive strategy. However, the cross-sex genetic correlation was estimated to be close to zero. Such small correlations might arise because male reproductive success achieved through extra-pair paternity was strongly positively genetically correlated with success achieved through within pair paternity, implying that the same successful males commonly sire offspring produced by polyandrous and monogamous females. Cross-sex indirect selection may consequently have limited capacity to drive evolution of female extra-pair reproduction, or hence underlying polyandry, in systems where multiple routes to paternity success exist. PMID- 30283675 TI - Last male sperm precedence is modulated by female remating rate in Drosophila melanogaster. AB - Following multiple matings, sperm from different males compete for fertilization within the female reproductive tract. In many species, this competition results in an unequal sharing of paternity that favors the most recent mate, termed last male sperm precedence (LMSP). Much of our understanding of LMSP comes from studies in Drosophila melanogaster that focus on twice-mated females with standardized latencies between successive matings. Despite accumulating evidence indicating that females often mate with more than two males and exhibit variation in the latency between matings, the consequences of mating rate on LMSP are poorly understood. Here, we developed a paradigm utilizing D. melanogaster in which females remated at various time intervals with either two or three transgenic males that produce fluorescent sperm (green, red, or blue). This genetic manipulation enables paternity assessment of offspring and male-specific sperm fate examination in female reproductive tracts. We found that remating latency had no relationship with LMSP in females that mated with two males. However, LMSP was significantly reduced in thrice-mated females with short remating intervals; coinciding with reduced last-male sperm storage. Thus, female remating rate influences the relative share of paternity, the overall clutch paternity diversity, and ultimately the acquisition of indirect genetic benefits to potentially maximize female reproductive success. PMID- 30283676 TI - A general model of biological signals, from cues to handicaps. AB - Organisms sometimes appear to use extravagant traits, or "handicaps", to signal their quality to an interested receiver. Before they were used as signals, many of these traits might have been selected to increase with individual quality for reasons apart from conveying information, allowing receivers to use the traits as "cues" of quality. However, current theory does not explain when and why cues of individual quality become exaggerated into costly handicaps. We address this here, using a game-theoretic model of adaptive signalling. Our model predicts that: (1) signals will honestly reflect signaler quality whenever there is a positive relationship between individual quality and the signalling trait's naturally selected, non-informational optimum; and (2) the slope of this relationship will determine the amount of costly signal exaggeration, with more exaggeration favored when the slope is more shallow. A shallow slope means that a lower quality male would pay only a small fitness cost to have the same trait value as a higher quality male, and this drives the exaggeration of signals as high-quality signalers are selected to distinguish themselves. Our model reveals a simple and potentially widespread mechanism for ensuring signal honesty and predicts a natural continuum of signalling strategies, from cost-free cues to costly handicaps. PMID- 30283674 TI - Strong hybrid male incompatibilities impede the spread of a selfish chromosome between populations of a fly. AB - Meiotically driving sex chromosomes manipulate gametogenesis to increase their transmission at a cost to the rest of the genome. The intragenomic conflicts they produce have major impacts on the ecology and evolution of their host species. However, their ecological dynamics remain poorly understood. Simple population genetic models predict meiotic drivers will rapidly reach fixation in populations and spread across landscapes. In contrast, natural populations commonly show spatial variation in the frequency of drivers, with drive present in clines or mosaics across species ranges. For example, Drosophila subobscura harbors a sex ratio distorting drive chromosome (SRs) at 15-25% frequency in North Africa, present at less than 2% frequency in adjacent southern Spain, and absent in other European populations. Here, we investigate the forces preventing the spread of the driver northward. We show that SRs has remained at a constant frequency in North Africa, and failed to spread in Spain. We find strong evidence that spread is impeded by genetic incompatibility between SRs and Spanish autosomal backgrounds. When we cross SRs from North Africa onto Spanish genetic backgrounds we observe strong incompatibilities specific to hybrids bearing SRs. The incompatibilities increase in severity in F2 male hybrids, leading to almost complete infertility. We find no evidence supporting an alternative hypothesis, that there is resistance to drive in Spanish populations. We conclude that the source of the stepped frequency variation is genetic incompatibility between the SRs chromosome and the genetic backgrounds of the adjacent population, preventing SRs spreading northward. The low frequency of SRs in South Spain is consistent with recurrent gene flow across the Strait of Gibraltar combined with selection against the SRs element through genetic incompatibility. This demonstrates that incompatibilities between drive chromosomes and naive populations can prevent the spread of drive between populations, at a continental scale. PMID- 30283677 TI - Recent admixture between species of the fungal pathogen Histoplasma. AB - Hybridization between species of pathogens has the potential to speed evolution of virulence by providing the raw material for adaptation through introgression or by assembling new combinations of virulence traits. Fungal diseases are a source high morbidity, and remain difficult to treat. Yet the frequency of hybridization between fungal species has rarely been explored, and the functional role of introgressed alleles remains largely unknown. Histoplasma mississippiense and H. ohiense are sympatric throughout their range in North America and have distinct virulence strategies, making them an ideal system to examine the role introgression may play in fungal pathogens. We identified introgressed tracts in the genomes of a sample of H. mississippiense and H. ohiense isolates. We found strong evidence in each species for recent admixture, but introgressed alleles were present at low frequencies, suggesting that they were deleterious. Consistent with this, coding and regulatory sequences were strongly depleted within introgressed regions, whereas intergenic regions were enriched, indicating that functional introgressed alleles were frequently deleterious in their new genomic context. Surprisingly, we found only two isolates with substantial admixture: the H. mississippiense and H. ohiense genomic reference strains, WU24 and G217B, respectively. Our results show that recent admixture has occurred, that it is frequently deleterious and that conclusions based on studies of the H. mississippiense and H. ohiense type strains should be revisited with more representative samples from the genus. PMID- 30283678 TI - Evolution of bacteria specialization along an antibiotic dose gradient. AB - Antibiotic and pesticide resistance of pathogens are major and pressing worldwide issues. Resistance evolution is often considered in simplified ecological contexts: treated versus nontreated environments. In contrast, antibiotic usually present important dose gradients: from ecosystems to hospitals to polluted soils, in treated patients across tissues. However, we do not know whether adaptation to low or high doses involves different phenotypic traits, and whether these traits trade-off with each other. In this study, we investigated the occurrence of such fitness trade-offs along a dose gradient by evolving experimentally resistant lines of Escherichia coli at different antibiotic concentrations for ~400 generations. Our results reveal fast evolution toward specialization following the first mutational step toward resistance, along with pervasive trade-offs among different evolution doses. We found clear and regular fitness patterns of specialization, which converged rapidly from different initial starting points. These findings are consistent with a simple fitness peak shift model as described by the classical evolutionary ecology theory of adaptation across environmental gradients. We also found that the fitness costs of resistance tend to be compensated through time at low doses whereas they increase through time at higher doses. This cost evolution follows a linear trend with the log-dose of antibiotic along the gradient. These results suggest a general explanation for the variability of the fitness costs of resistance and their evolution. Overall, these findings call for more realistic models of resistance management incorporating dose-specialization. PMID- 30283679 TI - Genetic conflict with a parasitic nematode disrupts the legume-rhizobia mutualism. AB - Genetic variation for partner quality in mutualisms is an evolutionary paradox. One possible resolution to this puzzle is that there is a tradeoff between partner quality and other fitness-related traits. Here, we tested whether susceptibility to parasitism is one such tradeoff in the mutualism between legumes and nitrogen-fixing bacteria (rhizobia). We performed two greenhouse experiments with the legume Medicago truncatula. In the first, we inoculated each plant with the rhizobia Ensifer meliloti and with one of 40 genotypes of the parasitic root-knot nematode Meloidogyne hapla. In the second experiment, we inoculated all plants with rhizobia and half of the plants with a genetically variable population of nematodes. Using the number of nematode galls as a proxy for infection severity, we found that plant genotypes differed in susceptibility to nematode infection, and nematode genotypes differed in infectivity. Second, we showed that there was a genetic correlation between the number of mutualistic structures formed by rhizobia (nodules) and the number of parasitic structures formed by nematodes (galls). Finally, we found that nematodes disrupt the rhizobia mutualism: nematode-infected plants formed fewer nodules and had less nodule biomass than uninfected plants. Our results demonstrate that there is genetic conflict between attracting rhizobia and repelling nematodes in Medicago. If genetic conflict with parasitism is a general feature of mutualism, it could account for the maintenance of genetic variation in partner quality and influence the evolutionary dynamics of positive species interactions. PMID- 30283680 TI - Mutual fitness benefits arise during coevolution in a nematode-defensive microbe model. AB - Species interactions can shift along the parasitism-mutualism continuum. However, the consequences of these transitions for coevolutionary interactions remain unclear. We experimentally coevolved a novel species interaction between Caenorhabditis elegans hosts and a mildly parasitic bacterium, Enterococcus faecalis, with host-protective properties against virulent Staphylococcus aureus. Coinfections drove the evolutionary transition of the C. elegans-E. faecalis relationship toward a reciprocally beneficial interaction. As E. faecalis evolved to protect nematodes against S. aureus infection, hosts adapted by accommodating greater numbers of protective bacteria. The mutualism was strongest in pairings of contemporary coevolved populations. To generally assess the conditions under which these defensive mutualisms can arise and coevolve, we analyzed a model that showed that they are favored when mild parasites confer an intermediate level of protection. Our results reveal that coevolution can shape the transition of animal-parasite interactions toward defensive symbioses in response to coinfections. PMID- 30283681 TI - A note on measuring natural selection on principal component scores. AB - Measuring natural selection through the use of multiple regression has transformed our understanding of selection, although the methods used remain sensitive to the effects of multicollinearity due to highly correlated traits. While measuring selection on principal component (PC) scores is an apparent solution to this challenge, this approach has been heavily criticized due to difficulties in interpretation and relating PC axes back to the original traits. We describe and illustrate how to transform selection gradients for PC scores back into selection gradients for the original traits, addressing issues of multicollinearity and biological interpretation. In addition to reducing multicollinearity, we suggest that this method may have promise for measuring selection on high-dimensional data such as volatiles or gene expression traits. We demonstrate this approach with empirical data and examples from the literature, highlighting how selection estimates for PC scores can be interpreted while reducing the consequences of multicollinearity. PMID- 30283682 TI - Speciation genes are more likely to have discordant gene trees. AB - Speciation genes are responsible for reproductive isolation between species. By directly participating in the process of speciation, the genealogies of isolating loci have been thought to more faithfully represent species trees. The unique properties of speciation genes may provide valuable evolutionary insights and help determine the true history of species divergence. Here, we formally analyze whether genealogies from loci participating in Dobzhansky-Muller (DM) incompatibilities are more likely to be concordant with the species tree under incomplete lineage sorting (ILS). Individual loci differ stochastically from the true history of divergence with a predictable frequency due to ILS, and these expectations-combined with the DM model of intrinsic reproductive isolation from epistatic interactions-can be used to examine the probability of concordance at isolating loci. Contrary to existing verbal models, we find that reproductively isolating loci that follow the DM model are often more likely to have discordant gene trees. These results are dependent on the pattern of isolation observed between three species, the time between speciation events, and the time since the last speciation event. Results supporting a higher probability of discordance are found for both derived-derived and derived-ancestral DM pairs, and regardless of whether incompatibilities are allowed or prohibited from segregating in the same population. Our overall results suggest that DM loci are unlikely to be especially useful for reconstructing species relationships, even in the presence of gene flow between incipient species, and may in fact be positively misleading. PMID- 30283683 TI - Clines on the seashore: The genomic architecture underlying rapid divergence in the face of gene flow. AB - Adaptive divergence and speciation may happen despite opposition by gene flow. Identifying the genomic basis underlying divergence with gene flow is a major task in evolutionary genomics. Most approaches (e.g., outlier scans) focus on genomic regions of high differentiation. However, not all genomic architectures potentially underlying divergence are expected to show extreme differentiation. Here, we develop an approach that combines hybrid zone analysis (i.e., focuses on spatial patterns of allele frequency change) with system-specific simulations to identify loci inconsistent with neutral evolution. We apply this to a genome-wide SNP set from an ideally suited study organism, the intertidal snail Littorina saxatilis, which shows primary divergence between ecotypes associated with different shore habitats. We detect many SNPs with clinal patterns, most of which are consistent with neutrality. Among non-neutral SNPs, most are located within three large putative inversions differentiating ecotypes. Many non-neutral SNPs show relatively low levels of differentiation. We discuss potential reasons for this pattern, including loose linkage to selected variants, polygenic adaptation and a component of balancing selection within populations (which may be expected for inversions). Our work is in line with theory predicting a role for inversions in divergence, and emphasizes that genomic regions contributing to divergence may not always be accessible with methods purely based on allele frequency differences. These conclusions call for approaches that take spatial patterns of allele frequency change into account in other systems. PMID- 30283684 TI - Adaptive radiation along a deeply conserved genetic line of least resistance in Anolis lizards. AB - On microevolutionary timescales, adaptive evolution depends upon both natural selection and the underlying genetic architecture of traits under selection, which may constrain evolutionary outcomes. Whether such genetic constraints shape phenotypic diversity over macroevolutionary timescales is more controversial, however. One key prediction is that genetic constraints should bias the early stages of species divergence along "genetic lines of least resistance" defined by the genetic (co)variance matrix, G. This bias is expected to erode over time as species means and G matrices diverge, allowing phenotypes to evolve away from the major axis of variation. We tested for evidence of this signal in West Indian Anolis lizards, an iconic example of adaptive radiation. We found that the major axis of morphological evolution was well aligned with a major axis of genetic variance shared by all species despite separation times of 20-40 million years, suggesting that divergence occurred along a conserved genetic line of least resistance. Further, this signal persisted even as G itself evolved, apparently because the largest evolutionary changes in G were themselves aligned with the line of genetic least resistance. Our results demonstrate that the signature of genetic constraint may persist over much longer timescales than previously appreciated, even in the presence of evolving genetic architecture. This pattern may have arisen either because pervasive constraints have biased the course of adaptive evolution or because the G matrix itself has been shaped by selection to conform to the adaptive landscape. PMID- 30283685 TI - Lessons from a natural experiment: Allopatric morphological divergence and sympatric diversification in the Midas cichlid species complex are largely influenced by ecology in a deterministic way. AB - Explaining why some lineages diversify while others do not and how are key objectives in evolutionary biology. Young radiations of closely related species derived from the same source population provide an excellent opportunity to disentangle the relative contributions of possible drivers of diversification. In these settings, lineage-specific effects are shared and can be ruled out. Moreover, the relevant demographic and ecological parameters can be estimated accurately. Midas cichlid fish in Nicaragua have repeatedly colonized several crater lakes, diverged from the same source populations, and, interestingly, diversified in some of them but not others. Here, using the most comprehensive molecular and geometric morphometric data set on Midas cichlids to date (~20,000 SNPs, 12 landmarks, ~700 individuals), we aim to understand why and how crater lake populations diverge and why some of them are more prone to diversify in sympatry than others. Taking ancestor-descendant relationships into account, we find that Midas cichlids diverged in parallel from their source population mostly but not exclusively-by evolving more slender body shapes in all six investigated crater lakes. Admixture among crater lakes has possibly facilitated this process in one case, but overall, admixture and secondary waves of colonization cannot predict morphological divergence and intralacustrine diversification. Instead, morphological divergence is larger the more dissimilar a crater lake is compared to the source lake and happens rapidly after colonization followed by a slow-down with time. Our data also provide some evidence that founder effects may positively contribute to divergence. The depth of a crater lake is positively associated with variation in body shapes (and number of species), presumably by providing more ecological opportunities. In conclusion, we find that parallel morphological divergence in allopatry and the propensity for diversification in sympatry across the entire Midas cichlid fish radiation is partly predictable and mostly driven by ecology. PMID- 30283686 TI - Convergent phenotypic evolution of the visual system via different molecular routes: How Neotropical cichlid fishes adapt to novel light environments. AB - How predictable is evolution? This remains a fundamental but contested issue in evolutionary biology. When independent lineages colonize the same environment, we are presented with a natural experiment that allows us to ask if genetic and ecological differences promote species-specific evolutionary outcomes or whether species phenotypically evolve in a convergent manner in response to shared selection pressures. If so, are the molecular mechanisms underlying phenotypic convergence the same? In Nicaragua, seven species of cichlid fishes concurrently colonized two novel photic environments. Hence, their visual system represents a compelling model to address these questions, particularly since the adaptive value of phenotypic changes is well-understood. By analyzing retinal transcriptomes, we found that differential expression of genes responsible for color vision (cone opsins and cyp27c1) produced rapid and mostly convergent changes of predicted visual sensitivities. Notably, these changes occurred in the same direction in all species although there were differences in underlying gene expression patterns illustrating nonconvergence at the molecular level. Adaptive phenotypes evolved deterministically, even when species differ substantially in ecology and genetic variation. This provides strong evidence that phenotypic evolution of the visual system occurred in response to similar selective forces of the photic environment. PMID- 30283687 TI - Parallel genetic adaptation across environments differing in mode of growth or resource availability. AB - Evolution experiments have demonstrated high levels of genetic parallelism between populations evolving in identical environments. However, natural populations evolve in complex environments that can vary in many ways, likely sharing some characteristics but not others. Here, we ask whether shared selection pressures drive parallel evolution across distinct environments. We addressed this question in experimentally evolved populations founded from a clone of the bacterium Burkholderia cenocepacia. These populations evolved for 90 days (approximately 600 generations) under all combinations of high or low carbon availability and selection for either planktonic or biofilm modes of growth. Populations that evolved in environments with shared selection pressures (either level of carbon availability or mode of growth) were more genetically similar to each other than populations from environments that shared neither characteristic. However, not all shared selection pressures led to parallel evolution. Genetic parallelism between low-carbon biofilm and low-carbon planktonic populations was very low despite shared selection for growth under low-carbon conditions, suggesting that evolution in low-carbon environments may generate stronger trade offs between biofilm and planktonic modes of growth. For all environments, a population's fitness in a particular environment was positively correlated with the genetic similarity between that population and the populations that evolved in that particular environment. Although genetic similarity was low between low carbon environments, overall, evolution in similar environments led to higher levels of genetic parallelism and that genetic parallelism, in turn, was correlated with fitness in a particular environment. PMID- 30283688 TI - The effects of haploid selection on Y chromosome evolution in two closely related dioecious plants. AB - The evolution of sex chromosomes is usually considered to be driven by sexually antagonistic selection in the diploid phase. However, selection during the haploid gametic phase of the lifecycle has recently received theoretical attention as possibly playing a central role in sex chromosome evolution, especially in plants where gene expression in the haploid phase is extensive. In particular, male-specific haploid selection might favor the linkage of pollen beneficial alleles to male sex determining regions on incipient Y chromosomes. This linkage might then allow such alleles to further specialize for the haploid phase. Purifying haploid selection is also expected to slow the degeneration of Y linked genes expressed in the haploid phase. Here, we examine the evolution of gene expression in flower buds and pollen of two species of Rumex to test for signatures of haploid selection acting during plant sex chromosome evolution. We find that genes with high ancestral pollen expression bias occur more often on sex chromosomes than autosomes and that genes on the Y chromosome are more likely to become enriched for pollen expression bias. We also find that genes with low expression in pollen are more likely to be lost from the Y chromosome. Our results suggest that sex-specific haploid selection during the gametophytic stage of the lifecycle may be a major contributor to several features of plant sex chromosome evolution. PMID- 30283689 TI - Timing malaria transmission with mosquito fluctuations. AB - Temporal variations in the activity of arthropod vectors can dramatically affect the epidemiology and evolution of vector-borne pathogens. Here, we explore the "Hawking hypothesis", which states that these pathogens may evolve the ability to time investment in transmission to match the activity of their vectors. First, we use a theoretical model to identify the conditions promoting the evolution of time-varying transmission strategies in pathogens. Second, we experimentally test the "Hawking hypothesis" by monitoring the within-host dynamics of Plasmodium relictum throughout the acute and the chronic phases of the bird infection. We detect a periodic increase of parasitemia and mosquito infection in the late afternoon that coincides with an increase in the biting activity of its natural vector. We also detect a positive effect of mosquito bites on Plasmodium replication in the birds both in the acute and in the chronic phases of the infection. This study highlights that Plasmodium parasites use two different strategies to increase the match between transmission potential and vector availability. We discuss the adaptive nature of these unconditional and plastic transmission strategies with respect to the time scale and the predictability of the fluctuations in the activity of the vector. PMID- 30283690 TI - Decomposing parasite fitness reveals the basis of specialization in a two-host, two-parasite system. AB - The ecological specialization of parasites-whether they can obtain high fitness on very few or very many different host species-is a determining feature of their ecology. In order to properly assess specialization, it is imperative to measure parasite fitness across host species; to understand its origins, fitness must be decomposed into the underlying traits. Despite the omnipresence of parasites with multiple hosts, very few studies assess and decompose their specialization in this way. To bridge this gap, we quantified the infectivity, virulence, and transmission rate of two parasites, the horizontally transmitted microsporidians Anostracospora rigaudi and Enterocytospora artemiae, in their natural hosts, the brine shrimp Artemia parthenogenetica and Artemia franciscana. Our results demonstrate that each parasite performs well on one of the two host species (A. rigaudi on A. parthenogenetica, and E. artemiae on A. franciscana), and poorly on the other. This partial specialization is driven by high infectivity and transmission rates in the preferred host, and is associated with maladaptive virulence and large costs of resistance in the other. Our study represents a rare empirical contribution to the study of parasite evolution in multihost systems, highlighting the negative effects of under- and overexploitation when adapting to multiple hosts. PMID- 30283691 TI - Large-effect mutations generate trade-off between predatory and locomotor ability during arms race coevolution with deadly prey. AB - Adaptive evolution in response to one selective challenge may disrupt other important aspects of performance. Such evolutionary trade-offs are predicted to arise in the process of local adaptation, but it is unclear if these phenotypic compromises result from the antagonistic effects of simple amino acid substitutions. We tested for trade-offs associated with beneficial mutations that confer tetrodotoxin (TTX) resistance in the voltage-gated sodium channel (NaV1.4) in skeletal muscle of the common garter snake (Thamnophis sirtalis). Separate lineages in California and the Pacific Northwest independently evolved TTX resistant changes to the pore of NaV1.4 as a result of arms race coevolution with toxic prey, newts of the genus Taricha. Snakes from the California lineage that were homozygous for an allele known to confer large increases in toxin resistance (NaV1.4LVNV) had significantly reduced crawl speed compared to individuals with the ancestral TTX-sensitive channel. Heterologous expression of native snake NaV1.4 proteins demonstrated that the same NaV1.4LVNV allele confers a dramatic increase in TTX resistance and a correlated decrease in overall channel excitability. Our results suggest the same mutations that accumulate during arms race coevolution and beneficially interfere with toxin-binding also cause changes in electrophysiological function of the channel that may affect organismal performance. This trade-off was only evident in the predator lineage where coevolution has led to the most extreme resistance phenotype, determined by four critical amino acid substitutions. If these biophysical changes also translate to a fitness cost-for example, through the inability of T. sirtalis to quickly escape predators-then pleiotropy at this single locus could contribute to observed variation in levels of TTX resistance across the mosaic landscape of coevolution. PMID- 30283692 TI - Evolutionary origins of vocal mimicry in songbirds. AB - Vocal learning is an important behavior in oscines (songbirds). Some songbird species learn heterospecific sounds as well as conspecific vocalizations. The emergence of vocal mimicry is necessarily tied to the evolution of vocal learning, as mimicry requires the ability to acquire sounds through learning. As such, tracking the evolutionary origins of vocal mimicry may provide insights into the causes of variation in song learning programs among songbirds. We compiled a database of known vocal mimics that comprised 339 species from 43 families. We then traced the evolutionary history of vocal mimicry across the avian phylogeny using ancestral trait reconstruction on a dataset of oscine passerines for which vocalizations have been described. We found that the common ancestor to oscines was unlikely to mimic sounds, suggesting that song learning evolved with mechanisms to constrain learning to conspecific models. Mimicry then evolved repeatedly within the songbird clade, either through relaxation of constraints on conspecific learning or through selection for active vocal mimicry. Vocal mimicry is likely ancestral in only a handful of clades, and we detect many instances of independent origins of mimicry. Our analysis underscores the liability of vocal mimicry in songbirds, and highlights the evolutionary flexibility of song learning mechanisms. PMID- 30283693 TI - Dramatic evolution of body length due to postembryonic changes in cell size in a newly discovered close relative of Caenorhabditis elegans. AB - Understanding morphological diversity-and morphological constraint-has been a central question in evolutionary biology since its inception. Nematodes of the genus Caenorhabditis, which contains the well-studied model organism C. elegans, display remarkable morphological consistency in the face of extensive genetic divergence. Here, we provide a description of the broad developmental patterns of a newly discovered species, C. sp. 34, which was isolated from fresh figs in Okinawa and which is among the closest known relatives of C. elegans. C. sp. 34 displays an extremely large body size; it can grow to be nearly twice as long as C. elegans and all other known members of the genus. Observations of the timing of developmental milestones reveal that C. sp. 34 develops about twice as slowly as C. elegans. Measurements of embryonic and larval size show that the size difference between C. sp. 34 and C. elegans is largely due to postembryonic events, particularly during the transition from larval to adult stages. This difference in size is not attributable to differences in germ line chromosome number or the number of somatic cells. The overall difference in body size is therefore largely attributable to changes in cell size via increased cytoplasmic volume. Because of its close relationship to C. elegans, the distinctness of C. sp. 34 provides an ideal system for the detailed analysis of evolutionary diversification. The context of over 40 years of C. elegans developmental genetics also reveals clues into how natural selection and developmental constraint act jointly to promote patterns of morphological stasis and divergence in this group. PMID- 30283694 TI - Nonclonal coloniality: Genetically chimeric colonies through fusion of sexually produced polyps in the hydrozoan Ectopleura larynx. AB - Hydrozoans typically develop colonies through asexual budding of polyps. Although colonies of Ectopleura are similar to other hydrozoans in that they consist of multiple polyps physically connected through continuous epithelia and shared gastrovascular cavity, Ectopleura larynx does not asexually bud polyps indeterminately. Instead, after an initial phase of limited budding in a young colony, E. larynx achieves its large colony size through the aggregation and fusion of sexually (nonclonally) produced polyps. The apparent chimerism within a physiologically integrated colony presents a potential source of conflict between distinct genetic lineages, which may vary in their ability to access the germline. To determine the extent to which the potential for genetic conflict exists, we characterized the types of genetic relationships between polyps within colonies, using a RAD-Seq approach. Our results indicate that E. larynx colonies are indeed comprised of polyps that are clones and sexually reproduced siblings and offspring, consistent with their life history. In addition, we found that colonies also contain polyps that are genetically unrelated, and that estimates of genome-wide relatedness suggests a potential for conflict within a colony. Taken together, our data suggest that there are distinct categories of relationships in colonies of E. larynx, likely achieved through a range of processes including budding, regeneration, and fusion of progeny and unrelated polyps, with the possibility for a genetic conflict resolution mechanism. Together these processes contribute to the reevolution of the ecologically important trait of coloniality in E. larynx. PMID- 30283695 TI - Ageing with a silver-spoon: A meta-analysis of the effect of developmental environment on senescence. AB - What determines variation between individuals in how they senesce, and are environmental conditions experienced during development relevant to late-life performance? We report a meta-analysis of studies of wild populations to determine how the quality of the environment experienced during development affects rates of survival and reproductive senescence. From studies of 14 bird or mammal species, we calculated effect sizes for the interaction between the effects of environmental quality during development and age in predicting survival (N = 18) or reproduction (N = 30) over time in late life. We found no evidence that developmental environment affected rates of survival senescence (betamean = -1.2 * 10-4 +/- 0.022SE). However, a better developmental environment was associated with slower rates of reproductive senescence in late life (betamean = 0.062 +/- 0.023SE), indicating a small, but significant, "silver spoon" effect of early-life conditions that persisted through to late life. Our results illustrate how the effects of environmental conditions during development can persist throughout life, and indicate one possible cause of phenotypic plasticity in senescence. PMID- 30283696 TI - Coadapted genomes and selection on hybrids: Fisher's geometric model explains a variety of empirical patterns. AB - Natural selection plays a variety of roles in hybridization, speciation, and admixture. Most research has focused on two extreme cases: crosses between closely related inbred lines, where hybrids are fitter than their parents, or crosses between effectively isolated species, where hybrids suffer severe breakdown. But many natural populations must fall into intermediate regimes, with multiple types of gene interaction, and these are more difficult to study. Here, we develop a simple fitness landscape model, and show that it naturally interpolates between previous modeling approaches, which were designed for the extreme cases, and invoke either mildly deleterious recessives, or discrete hybrid incompatibilities. Our model yields several new predictions, which we test with genomic data from Mytilus mussels, and published data from plants (Zea, Populus, and Senecio) and animals (Mus, Teleogryllus, and Drosophila). The predictions are generally supported, and the model explains a number of surprising empirical patterns. Our approach enables novel and complementary uses of genome-wide datasets, which do not depend on identifying outlier loci, or "speciation genes" with anomalous effects. Given its simplicity and flexibility, and its predictive successes with a wide range of data, the approach should be readily extendable to other outstanding questions in the study of hybridization. PMID- 30283697 TI - Positive and balancing selection on SLC18A1 gene associated with psychiatric disorders and human-unique personality traits. AB - Maintenance of genetic variants susceptible to psychiatric disorders is one of the intriguing evolutionary enigmas. The present study detects three psychiatric disorder-relevant genes (CLSTN2, FAT1, and SLC18A1) that have been under positive selection during the human evolution. In particular, SLC18A1 (vesicular monoamine transporter 1; VMAT1) gene has a human-unique variant (rs1390938, Thr136Ile), which is associated with bipolar disorders and/or the anxiety-related personality traits. 136Ile shows relatively high (20-61%) frequency in non-African populations, and Tajima's D reports a significant peak around the Thr136Ile site, suggesting that this polymorphism has been positively maintained by balancing selection in non-African populations. Moreover, Coalescent simulations predict that 136Ile originated around 100,000 years ago, the time being generally associated with the Out-of-Africa migration of modern humans. Our study sheds new light on a gene in monoamine pathway as a strong candidate contributing to human unique psychological traits. PMID- 30283698 TI - Lineages evolved under stronger sexual selection show superior ability to invade conspecific competitor populations. AB - Despite limitations on offspring production, almost all multicellular species use sex to reproduce. Sex gives rise to sexual selection, a widespread force operating through competition and choice within reproduction, however, it remains unclear whether sexual selection is beneficial for total lineage fitness, or if it acts as a constraint. Sexual selection could be a positive force because of selection on improved individual condition and purging of mutation load, summing into lineages with superior fitness. On the other hand, sexual selection could negate potential net fitness through the actions of sexual conflict, or because of tensions between investment in sexually selected and naturally selected traits. Here, we explore these ideas using a multigenerational invasion challenge to measure consequences of sexual selection for the overall net fitness of a lineage. After applying experimental evolution under strong versus weak regimes of sexual selection for 77 generations with the flour beetle Tribolium castaneum, we measured the overall ability of introductions from either regime to invade into conspecific competitor populations across eight generations. Results showed that populations from stronger sexual selection backgrounds had superior net fitness, invading more rapidly and completely than counterparts from weak sexual selection backgrounds. Despite comprising only 10% of each population at the start of the invasion experiment, colonizations from strong sexual selection histories eventually achieved near-total introgression, almost completely eliminating the original competitor genotype. Population genetic simulations using the design and parameters of our experiment indicate that this invasion superiority could be explained if strong sexual selection had improved both juvenile and adult fitness, in both sexes. Using a combination of empirical and modeling approaches, our findings therefore reveal positive and wide-reaching impacts of sexual selection for net population fitness when facing the broad challenge of invading competitor populations across multiple generations. PMID- 30283699 TI - Don't throw out the sympatric speciation with the crater lake water: fine-scale investigation of introgression provides equivocal support for causal role of secondary gene flow in one of the clearest examples of sympatric speciation. AB - Genomic data has revealed complex histories of colonization and repeated gene flow previously unrecognized in some of the most celebrated examples of sympatric speciation and radiation. However, much of the evidence for secondary gene flow into these radiations comes from summary statistics calculated from sparse genomic sampling without knowledge of which specific genomic regions introgressed. This tells us little about how gene flow potentially influenced sympatric diversification. Here, we investigated whole genomes of Barombi Mbo crater lake cichlids for fine-scale patterns of introgression with neighboring riverine cichlid populations. We found evidence of secondary gene flow into the radiation scattered across <0.24% of the genome; however, from our analyses, it is not clear if the functional diversity in these regions contributed to the ecological, sexual, and morphological diversity found in the lake. Unlike similar studies, we found no obvious candidate genes for adaptive introgression and we cannot rule out that secondary gene flow was predominantly neutral with respect to the diversification process. We also found evidence for differential assortment of ancestral polymorphisms found in riverine populations between sympatric sister species, suggesting the presence of an ancestral hybrid swarm. Although the history of gene flow and colonization is more complicated than previously assumed, the lack of compelling evidence for secondary gene flow's role in species diversification suggests that we should not yet rule out one of the most celebrated examples of sympatric speciation in nature without a more thorough investigation of the timing and functional role of each introgressed region. PMID- 30283700 TI - Development of metastatic brain disease involves progression through lung metastases in EGFR mutated non-small cell lung cancer. AB - Lung cancer is often classified by the presence of oncogenic drivers, such as epidermal growth factor receptor (EGFR), rather than patterns of anatomical distribution. While metastatic spread may seem a random and unpredictable process, we explored the possibility of using its quantifiable nature as a measure of describing and comparing different subsets of disease. We constructed a database of 664 non-small cell lung cancer (NSCLC) patients treated at the University of Southern California Norris Comprehensive Cancer Center and the Los Angeles County Medical Center. Markov mathematical modeling was employed to assess metastatic sites in a spatiotemporal manner through every time point in progression of disease. Our findings identified a preferential pattern of primary lung disease progressing through lung metastases to the brain amongst EGFR mutated (EGFR m) NSCLC patients, with exon 19 deletions or exon 21 L858R mutations, as compared to EGFR wild type (EGFR wt). The brain was classified as an anatomic "sponge", with a higher ratio of incoming to outgoing spread, for EGFR m NSCLC. Bone metastases were more commonly identified in EGFR wt patients. Our study supports a link between the anatomical and molecular characterization of lung metastatic cancer. Improved understanding of the differential biology that drives discordant patterns of anatomic spread, based on genotype specific profiling, has the potential to improve personalized oncologic care. PMID- 30283701 TI - A Systematic Review on Prevention and Treatment of Nipple Pain and Fissure: Are They Curable? AB - Averagely 80% to 90% of breastfeeding women experience the nipple pain and fissures. The important factor for successful breastfeeding is to treat this problem. This study has done as a review with the aim of analysis of the clinical trials in the field of the prevention and treatment of the nipple fissures and pain due to the importance of breastfeeding. For this purpose, the key words of sore, nipples, fissure, trauma, wound, prevention, treatment, therapeutics, therapy, clinical trial, breastfeeding and their Persian synonyms and all of their possible combinations were searched in the national databases: SID and Iran Medex and Magiran, and in the international databases: PubMed, Scopus, Medline, Science direct by May 2017. The Jadad criterion was used to assess the quality of the articles and the articles with a score of 3 or more were included in this study. Finally, 48 clinical trials were reviewed that 17 of them (sample size 1801) scored 3 or more based on the Jadad criterion. Seven articles were also in the non- drug treatment group (sample size 491) and 2 articles in the drug treatment group (sample size 337) and 8 articles in the herbal treatment group (sample size 973).The results show that menthol and warm water compress as well as teaching the correct breastfeeding methods are effective treatments to prevent and treat the nipple pain and fissures. Moreover, applying the herbal medicine for prevention and treatment of the issues raised from breastfeeding may have beneficial such as Aloe vera, Portulaca olearacea. However, more studies with a great methodology are necessary to obtain more accurate evidence. PMID- 30283702 TI - Efficacy and Safety of Miniscalpel Acupuncture on Knee Osteoarthritis: - A randomized controlled pilot trial. AB - Objectives: We investigated the efficacy and safety of miniscalpel acupuncture (MA) for knee osteoarthritis (KOA) in an assessor-blinded randomized controlled pilot trial; this would provide information for a large-scale randomized controlled trial. Methods: Participants (n = 24) were recruited and randomly allocated to the MA group (experimental) or acupuncture group (control). The MA group received treatment once a week for 3 weeks (total of 3 treatments), while the acupuncture group received treatment two times per week for 3 weeks (total of 6 treatments). The primary outcome was pain as assessed by a visual analogue scale (VAS). The secondary outcomes (intensity of current pain, stiffness, and physical function) were assessed using the short-form McGill Pain Questionnaire (SF-MPQ) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Assessments were performed at baseline, 1, 2, and 3 during treatment and at week 5 (2 weeks after the end of treatment). Results: Of the 24 participants, 23 completed the study. Both groups showed significant improvements in VAS, SF MPQ, and WOMAC. However, there were no significant differences between the MA and acupuncture groups. No serious adverse event occurred and blood test results were within normal limits. Conclusion: Our results suggest that although both MA and acupuncture provide similar effects with regard to pain control in patients with KOA, MA may be more effective in providing pain relief because the same relief was obtained with fewer treatments. A large-scale clinical study is warranted to further clarify these findings. PMID- 30283703 TI - Teucrium polium L. Improved Heart Function and Inhibited Myocardial Apoptosis in Isolated Rat Heart Following Ischemia-Reperfusion Injury. AB - Objectives: Myocardial reperfusion is the only logical cure for ischemic heart disease. However, ischemic-reperfusion (I/R) injury is one of the underlying factors facilitating and accelerating the apoptosis in the myocardium. This study set to investigate the impact of Teucrium polium (TP) hydro-alcoholic extract on I/R induced apoptosis in the isolated rat heart. Methods: Isolated rat hearts were classified into six groups. The control samples were subjected to 80 min of perfusion with Krebs-Henseleit bicarbonate (KHB) buffer; in control-ischemia group, after primary perfusion (20 min) the hearts were exposed to global ischemia (20 min) and reperfusion (40 min). Pretreated groups were perfused with 500 MUM of vitamin C and various TP concentrations (0.5, 1, 2 mg/ml) for 20 min, and then the hearts were exposed to ischemia and reperfusion for 20 min and 40 min, respectively. Cardiodynamic parameters including rate pressure product (RPP), heart rate (HR), the maximum up/down rate of left ventricular pressure (+/ dp/dt), left ventricular developed pressure (LVDP), and coronary artery flow (CF) were achieved from Lab Chart software data. The Bax and BCl-2 gene expressions were measured in heart samples. Results: Hearts treated with TP extract and vit C represented a meaningful improvement in cardiac contractile function and CF. The overexpression of Bcl-2, downregulation of Bax, and improvement of apoptotic index (Bax/Bcl-2) were observed in pretreated TP extract and vit C hearts. Conclusion: The TP extract was found to ameliorate the cardiac function in the reperfused myocardium. Also, it can hinder apoptotic pathways causing cardioprotection. PMID- 30283704 TI - Ethanol and Methanol Concentration in Commonly Used Brands of Ma-al-shaeer in Iran: Estimation of Dietary Intakes and Risk Assessment. AB - Objectives: Ma-al-shaeer is a popular beverage in Islamic countries. The aim of this study was to determine the concentrations of methanol and ethanol in most consumed brands of Ma-al-shaeer in Iran. Methods: Eighty-one Ma-al-shaeer samples which commonly used in Iran were provided. Methanol and ethanol contents were determined by gas chromatography with flame ionization detector. Results: The mean methanol concentrations in Iranian and foreign brands was 129.84+/-205.38 mg/L and 110.157+/-135.98 mg/L, respectively. Although mean ethanol contents of Iranian brands was 1.2+/-2.41 mg/L, ethanol level in foreign ones was lower than LOQ. Conclusion: Since the most Ma-al-shaeer brands had methanol pollution at different levels establishment of a definitive relationship between the methanol content and toxicological effects seem to be vital. EDI of methanol for Iranian people through consumption of Ma-al-shaeer was determined 0.023mg/kg bw/day. PMID- 30283705 TI - Auraptene Inhibits Migration and Invasion of Cervical and Ovarian Cancer Cells by Repression of Matrix Metalloproteinasas 2 and 9 Activity. AB - Objectives: Auraptene, a natural citrus coumarin, found in plants of Rutaceae and Apiaceae families. In this study, we investigated the effects of auraptene on tumor migration, invasion and matrix metalloproteinase (MMP)-2 and -9 enzymes activity. Methods: The effects of auraptene on the viability of A2780 and Hela cell lines was evaluated by MTT assay. Wound healing migration assay and Boyden chamber assay were determined the effect of auraptene on migration and cell invasion, respectively. MMP-2 and MMP-9 activities were analyzed by gelatin zymography assay. Results: Auraptene reduced A2780 cell viability. The results showed that auraptene inhibited in vitro migration and invasion of both cells. Furthermore, cell invasion ability suppressed at 100MUM auraptene in Hela cells and at 25, 50MUM in A2780 cell line. Gelatin zymography showed that for Hela cell line, auraptene suppressed MMP-2 enzymatic activity in all concentrations and for MMP-9 at a concentration between 12.5 to 100MUM in A2780 cell line. Conclusion: Auraptene inhibited migration and invasion of human cervical and ovarian cancer cells in vitro by possibly inhibitory effects on MMP-2 and MMP-9 activity. PMID- 30283706 TI - Quercus Brantii Lindl. Vaginal Douche Versus Clotrimazole on Vaginal Candidiasis: A Randomized Clinical Trial. AB - Objectives: Vaginal Candidiasis with an approximate prevalence of 30% is the second cause of vaginal infections. Antifungal azole is the first treatment for Vaginal Candidiasis; however, some side effects have been reported for this chemical medicine. Based on the antifungal activity of Inner Stratum of Quercus Brantii (Q. Brantii), the aim of our study was to compare the effects of vaginal douche of Q. Brantii extract and clotrimazole on vaginal candidiasis symptoms before and after the treatments, in women. Methods: 89 non-pregnant women with positive KOH test which is capable of identifying the presence of hyphae and mycelium by adding KOH (10%), and a positive vaginal candidiasis culture were randomly divided into two experimental groups, using permuted block randomization method. One group received clotrimazole vaginal cream (1%) and the other group received vaginal douche of Q. Brantii extract. Groups were treated for 7 days and KOH tests and cultures were evaluated again. Data were analyzed via chi-square and independent t-test, using SPSS software. Results: According to the results, there were no significant differences between experimental groups for demographic characteristics like age (p=0.403), BMI (p=0.911), educational levels (p=0.862) and contraceptive methods (p=0.702). Moreover, significant differences were seen in vaginal discharge between the groups after the treatments (P=0.043). Conclusion: The results suggested that the therapeutic effect of vaginal douche of Q. Brantii extract was approximately similar to that of clotrimazole vaginal cream. PMID- 30283707 TI - Statues and Improvement of Electronic Medical Record System in Traditional Korean Medicine. AB - Objectives: The study was to survey use of electronic medical records in subjects of Korean medicine doctors working for Korean medicine organizations and to contemplate ways to develop utilization of electronic medical records. Methods: On August 2017, it conducted online self-reported survey on subjects of Korean medicine doctors at Korean hospitals and clinics who agreed to participate in the study. A total 40 doctors in hospital and 279 doctors in clinic were included. The surveyed contents include kinds of electronic chart, reason for not using electronic medical records and problems with creation of medical records. Results: It finds that 100% of those working at Korean medicine hospitals and 86.4% of those at Korean medicine clinics have used electronic medical records. Subjects answered the biggest reason for not using electronic medical records was inconvenience. The most serious problems with creation of electronic medical records at Korean medicine organizations found in the study include there was no method of creation of medical records and no standardized terminology for use in electronic medical records. Conclusion: For utilization of electronic medical records at Korean medicine organizations, standardization of terminology, development of EMR in favour of its users and development of strategy that motivates use of EMR are required. PMID- 30283708 TI - Orthogonal Stimulus-Response as a Tool to Formulate Traditional Chinese Medicinal Herbal Combination: - New Scientific-Based TCM Herbal Formulating Method. AB - Objectives: There is an increasing number of complex diseases that are progressively more difficult to be controlled using the conventional "single compound, single target" approach as demonstrated in our current modern drug development. TCM might be the new cornerstone of treatment alternative when the current treatment option is no longer as effective or that we have exhausted it as an option. Orthogonal stimulus-response compatibility group study is one of the most frequently employed formulas to produce optimal herbal combination for treatment of multi-syndromic diseases. This approach could solve the relatively low efficacy single drug therapy usage and chronic adverse effects caused by long terms administration of drugs that has been reported in the field of pharmacology and medicine. Methods: The present review was based on the Science Direct database search for those related to the TCM and the development of antihypertensive TCM herbal combination using orthogonal stimulus-response compatibility group studies approach. Results: Recent studies have demonstrated that the orthogonal stimulus-response compatibility group study approach was most frequently used to formulate TCM herbal combination based on the TCM principles upon the selection of herbs, and the resulting formulated TCM formula exhibited desired outcomes in treating one of global concerned complex multi-syndromic diseases, the hypertension. These promising therapeutic effects were claimed to have been attributed by the holistic signaling mechanism pathways employed by the crude combination of herbs. Conclusion: The present review could serve as a guide and prove the feasibility of TCM principles to be used for future pharmacological drug research development. PMID- 30283709 TI - Acinar cell injury induced by inadequate unfolded protein response in acute pancreatitis. AB - Acute pancreatitis (AP) is an inflammatory disorder of pancreatic tissue initiated in injured acinar cells. Severe AP remains a significant challenge due to the lack of effective treatment. The widely-accepted autodigestion theory of AP is now facing challenges, since inhibiting protease activation has negligible effectiveness for AP treatment despite numerous efforts. Furthermore, accumulating evidence supports a new concept that malfunction of a self protective mechanism, the unfolded protein response (UPR), is the driving force behind the pathogenesis of AP. The UPR is induced by endoplasmic reticulum (ER) stress, a disturbance frequently found in acinar cells, to prevent the aggravation of ER stress that can otherwise lead to cell injury. In addition, the UPR's signaling pathways control NFkappaB activation and autophagy flux, and these dysregulations cause acinar cell inflammatory injury in AP, but with poorly understood mechanisms. We therefore summarize the protective role of the UPR in AP, propose mechanistic models of how inadequate UPR could promote NFkappaB's pro inflammatory activity and impair autophagy's protective function in acinar cells, and discuss its relevance to current AP treatment. We hope that insight provided in this review will help facilitate the research and management of AP. PMID- 30283710 TI - Gut microbiome profiling and colorectal cancer in African Americans and Caucasian Americans. AB - AIM: To determine whether and to what extent the gut microbiome is involved in regulating racial disparity in colorectal cancer (CRC). METHODS: All patients were recruited and experiments were performed in accordance with the relevant guidelines and regulations by the Institutional Review Boards (IRB), committees of the John D. Dingell VAMC and Wayne State University guidelines. African American (AA) and Caucasian American (CA) patients were scheduled for an outpatient screening for colonoscopy, and no active malignancy volunteer patients were doubly consented, initially by the gastroenterologist and later by the study coordinator, for participation in the study. The gut microbial communities in colonic effluents from AAs and CAs were examined using 16sRNA profiling, and bacterial identifications were validated by performing SYBR-based Real Time PCR. For metagenomic analysis to characterize the microbial communities, multiple software/tools were used, including Metastats and R statistical software. RESULTS: It is generally accepted that the incidence and mortality of CRC is higher in AAs than in CAs. However, the reason for this disparity is not well understood. We hypothesize that the gut microbiome plays a role in regulating this disparity. Indeed, we found significant differences in species richness and diversity between AAs and CAs. Bacteroidetes was more abundant in AAs than in CAs. In particular, the pro-inflammatory bacteria Fusobacterium nucleatum and Enterobacter species were significantly higher in AAs, whereas probiotic Akkermansia muciniphila and Bifidobacterium were higher in CAs. The polyphyletic Clostridia class showed a divergent pattern, with Clostridium XI elevated in AAs, and Clostridium IV, known for its beneficial function, higher in CAs. Lastly, the AA group had decreased microbial diversity overall in comparison to the CA group. In summary, there were significant differences in pro-inflammatory bacteria and microbial diversity between AA and CA, which may help explain the CRC disparity between groups. CONCLUSION: Our current investigation, for the first time, demonstrates microbial dysbiosis between AAs and CAs, which could contribute to the racial disparity of CRC. PMID- 30283711 TI - Current State and Future of Biologic Therapies in the Treatment of Asthma in Children. AB - There is increasing recognition of phenotypic variability in pediatric asthma, providing the opportunity for a more personalized approach to therapy. Increasingly biologic therapies, in particular those targeting the "allergic" (or T helper 2) pathway, are being considered for children with severe asthma. However, there is a great deal of variability in the extent these biologic therapies have been studied in children, as well as efficacy of results thus far. The goal of this article is to review the mechanism of action, efficacy, and potential predictive and monitoring biomarkers of the biologic medications focusing on the pediatric population, in an effort to establish a more personalized approach to asthma in the pediatric population for the 21st century. PMID- 30283713 TI - Allergic Diseases and Immune-Mediated Food Disorders in Pediatric Acute-Onset Neuropsychiatric Syndrome. AB - Background: The prevalence and impact of allergic and immune-mediated food disorders in pediatric acute-onset neuropsychiatric syndrome (PANS) are mostly unknown. Objective: We sought to explore the prevalence of atopic dermatitis (AD), asthma, allergic rhinitis (AR), IgE-mediated food allergies (FAs), and other immune-mediated food disorders requiring food avoidance in patients with PANS. In addition, to further understand the extent of food restriction in this population, we investigated the empiric use of dietary measures to improve PANS symptoms. Methods: Pediatric patients in a PANS Clinic and Research Program were given surveys regarding their caregiver burdens, allergic and food-related medical history, and whether food elimination resulted in perception of improvement of PANS symptoms. A review of health records was conducted to confirm that all responses in the survey were concordant with documentation of each patient's medical chart. Results: Sixty-nine (ages 4-20 years) of 80 subjects who fulfilled PANS criteria completed the surveys. Thirteen (18.8%) had AD, 11 (15.9%) asthma, 33 (47.8%) AR, 11 (15.9%) FA, 1 (1.4%) eosinophilic gastrointestinal disorders, 1 (1.4%) food protein-induced enterocolitis syndrome, 3 (4.3%) milk protein-induced proctocolitis syndrome, and 3 (4.3%) celiac disease. Thirty subjects (43.5%) avoided foods due to PANS; elimination of gluten and dairy was most common and was associated with perceived improvement of PANS symptoms (by parents). This perceived improvement was not confirmed with objective data. Conclusions: The prevalence of allergic and immune-mediated food disorders in PANS is similar to the general population as reported in the literature, with the exception of AR that appears to be more prevalent in our PANS cohort. More research will be required to establish whether diet or allergies influence PANS symptoms. PMID- 30283712 TI - Perception of Pulmonary Function in Children with Asthma and Cystic Fibrosis. AB - Background: Under-perception of pulmonary dysfunction may delay appropriate treatment, while over-perception may result in unnecessary treatments. Objectives: To evaluate the ability of patients with asthma or cystic fibrosis and their subspecialty caregivers to assess changes in lung function based on their subjective clinical impressions. Methods: Patients were asked to qualitatively describe how they felt compared to their prior visit (same/better/worse) and to quantitatively estimate their forced expiratory volume in 1 s (FEV1) after being reminded of their FEV1 at the prior visit. Providers made similar estimates based on history and physical examination and knowledge of prior FEV1. After adjusting for relevant clinical covariates, lung function estimates were categorized as accurate (+/-5% of measured FEV1), overestimated (>5% above measured), and underestimated (>5% below measured). Results: One hundred nine patients estimated FEV1 on 179 occasions. Concordance between patient qualitative assessment and FEV1-based categories was low (kappa = 0.08); 44% of patients reported feeling better than the FEV1-based category showed. Quantitatively, 56% of patient estimates were accurate, 18% were underestimated, and 26% overestimated; accuracy improved with age (odds ratio = 1.16, P = 0.01). Concordance between provider qualitative assessments and FEV1-based category was moderate (kappa = 0.35); about 19% said their patient looked better than the FEV1 based category showed. Quantitatively, 65% of provider estimates were accurate, 16% were underestimated, and 19% were overestimated; accuracy improved with years of experience. Conclusions: Patients' and providers' perceptions of lung function were low to moderately accurate. Relying on subjective impression may place patients at risk for unnecessary treatments or increased morbidity. These findings highlight the importance of objective lung function assessment. PMID- 30283715 TI - One burr-hole craniotomy: Modified presigmoid approach in Helsinki Neurosurgery. AB - Background: In this video abstract, we present a one burr-hole craniotomy for a modified presigmoid approach developed in Helsinki Neurosurgery to access the space extended to both middle and posterior fossa. Thus, indications for this approach are lesions that extend to both middle and posterior fossa, petroclival tumors, basilar tip aneurysms located extremely low below the posterior clinoid process, trunk basilar aneurysms, and bypass procedures from the P2 segment of the posterior cerebral artery. The procedure is composed by three stages: a temporal and presigmoid craniotomy, a partial petromastoidectomy, and the dura opening with section of the superior petrosal sinus (SPS) and the tentorium. Even though some risks related to the opening of the mastoid cells or cut of the SPS may exist, benefits of this optimized craniotomy are higher compared with the complications. Case Description: The patient with a giant petroclival meningioma is placed in park bench position and spinal drainage is inserted. Skin incision starts in front of the ear curve going to 1 inch behind the mastoid line. Strong retraction with hooks keeps a clean space for the craniotomy. Hemostatic Raney clips are placed at the superior border of the skin flap. A burr-hole is made at the most cranial part of the temporal bone. After the detachment of the dura with long flexible blunt dissectors, the craniotomy is performed to expose the sigmoid sinus, the SPS and the dura of the inferior temporal lobe, and the floor of the middle fossa. Aiming to access the posterior fossa by a presigmoid route, a partial petromastoidectomy is performed preserving the semicircular canals. Few drill holes are made for tack-up sutures. Once we properly reach the dura of the middle and posterior fossa, dura of the temporal lobe and later, the presigmoid dura are opened joining at the level of the SPS. The SPS, which is running over the petrous bone between the posterior and the middle fossa, is coagulated, ligated, and cut. After SPS is sectioned, the tentorium is cut anterior to the drainage of vein of Labbe and posterior to the deep tentorial insertion of the fourth nerve. Finally, special care should be taken to seal the opened mastoid cells with muscle and glue, and for the hermetic dura closure using pericranium or temporal muscle aponeurosis. Conclusion: The described one burr-hole craniotomy may represent the more efficient approach for the management of the deep and hardly accessible lesions extended to both middle and posterior fossa.

PMID- 30283714 TI - Seizure freedom from temporal lobe epilepsy with mesial temporal lobe tumor by tumor removal alone without hippocampectomy despite remaining abnormal discharges on intraoperative electrocorticography: Report of two pediatric cases and reconsideration of the surgical strategy. AB - Background: In the surgical treatment of temporal lobe epilepsy with mesial temporal lobe tumor, whether to remove the hippocampus aiming for a better seizure outcome in addition to removing the tumor is a dilemma. Two pediatric cases treated successfully with tumor removal alone are presented. Case Description: The first case was an 11-year-old girl with a ganglioglioma in the left uncus, and the second case was a 9-year-old girl with a pleomorphic xanthoastrocytoma in the left parahippocampal gyrus. In both cases, the hippocampus was not invaded, merely compressed by the tumor. Tumor removal was performed under intraoperative electrocorticography (ECoG) monitoring. After tumor removal, abnormal discharges remained at the hippocampus and adjacent temporal cortices, but further surgical interventions were not performed. The seizures disappeared completely in both cases. Conclusions: When we must decide whether to remove the hippocampus, the side of the lesion, the severity and chronicity of the seizures, and the presence of invasion to the hippocampus are the factors that should be considered. Abnormal discharges on ECoG at the hippocampus or adjacent cortices are one of the factors related to epileptogenicity, but it is simply a result of interictal irritation, and it is not an absolute indication for additional surgical intervention. PMID- 30283716 TI - One burr-hole craniotomy: Posterior interhemispheric approach in Helsinki Neurosurgery. AB - Background: In this video abstract, we present a one burr-hole craniotomy for the posterior interhemispheric approach developed in Helsinki Neurosurgery to access posteriorly the medial surface of cerebral hemispheres, falx cerebri, and deep midline cerebrovascular structures. Therefore, preoperative imaging is essential to achieve an optimal operative corridor for a safest and more effcient approach. Case Description: The patient with a papillary tumor of the pineal region is placed in sitting position. A midline single-layer skin incision is made in front of the superior sagittal sinus. Strong retraction maintains a clean space for craniotomy. Aiming to reduce the risk of sinus transgression or cortical veins damaging in the eloquent frontal-parietal area, a burr-hole is made over the superior sagittal sinus at the anterior border of the bone flap and the bone is detached from the dura posteriorly with blunt dissectors. Thus, proximal detachment of the dura under some visual control remains safe. A long blunt flexible dissector is used during this stage in case of elderly patients with an adherent dura. Craniotomy around the superior sagittal sinus is performed to expose 2-3 cm of the dura lateral to the sagittal sinus according to the exact location of the lesion. Moreover, craniotomy extends slightly over the contralateral side to allow some retraction of the sagittal sinus. Two cuts, from both sites of the burr-hole, are joined along the posterior midline. A few drill holes are made for tack-up sutures. Finally, a hemostatic agent covers the sagittal sinus and a sinus-based dura opening is performed under the microscope. Conclusion: The described one burr-hole craniotomy may represent a more efficient manner for performing a posterior interhemispheric approach.

PMID- 30283717 TI - Focused opening of the Sylvian fissure for the management of middle cerebral artery aneurysms. AB - Background: A wide opening of the Sylvian fissure (SF) regarding the treatment of middle cerebral artery (MCA) aneurysm allows us to ensure early proximal control by the proximal start of Sylvian dissection and enough comfort for the microsurgical manipulation and aneurysm clipping. However, major mechanical manipulation of arteries associated with blood oozing into the surgical field may increase the incidence of postoperative vasospasm. The risk of Sylvian venous injury is bigger, and the damage of the superior temporal gyrus increases the risk of postoperative epilepsy as well. A focused opening of the SF based on 18 years experience of a senior author is an alternative technique we present in this video abstract. Technique: A proper preoperative planning and an image-based anatomic orientation of the Sylvian opening together with a complete understanding of the microanatomy of the clipping field are essential requirements for a proper focused SF opening. A patient with an MCA bifurcation aneurysm is placed in supine position. The head elevated 20 cm above the cardiac level is slightly extended, rotated to the contralateral side, and tilted laterally. A lateral supraorbital approach is performed. After cerebrospinal fluid release and under high magnification, the opening place of the SF is identified. Thus, 10-15 mm opening is made with a sharp needle followed by microscissors. Under a keyhole concept, the M1 segment of the MCA is recognized, and the aneurysm is carefully dissected. A temporary clipping with a proximal control of the M1 segment is followed by a definitive clipping of the aneurysm. Postoperative imaging does not show any complication. Conclusion: The focused opening of the SF is a less invasive technique for the management of MCA bifurcation aneurysms. However, some extra considerations should be taken for large or giant aneurysms in which a wide opening of the SF might be required for a proper aneurysm manipulation, and for those deep MCA bifurcation aneurysms close to the internal carotid artery bifurcation, in which an anterograde dissection of the MCA might be more suitable.

AB - Background: In this video abstract, we present an intradural anterior clinoidectomy for management of some paraclinoid aneurysms. Quick adenosine cardiac arrest performed instead of an anterior clinoidectomy and proximal temporary clipping usually allows us a proximal control of aneurysms in Helsinki Neurosurgery. However, when the neck of the aneurysm remains hidden under the anterior clinoid process, or when some complex aneurysms have reduced space for placing temporary clips obstructing the definitive clipping, anterior clinoidectomy is the most available option. Technique: The patient with multiple intracranial aneurysms had a ruptured anterior cerebral artery aneurysm associated with a right middle cerebral artery aneurysm and a right small paraclinoid aneurysm. The patient underwent surgical clipping of all aneurysms by a right lateral supraorbital approach at one-stage surgery. After the associated aneurysms were clipped, the hidden paraclinoid aneurysm required an anterior clinoidectomy for definitive clipping. A small durotomy over the anterior clinoid process was made with microscissors after bipolar coagulation. Subsequently, the anterior clinoidectomy was performed under visual control with the use of an electric high-speed diamond drill (3 mm diameter). The direction and size of the drilling were performed according to the anatomical configuration and exact location of the aneurysm determined by the preoperative radiological analysis of the case. A definitive clip was applied after complete visualization of aneurysm. Postoperative computed tomography angiography demonstrated absence of complications. Conclusion: Anterior clinoidectomy is a useful procedure aiming at a proper definitive clipping of paraclinoid aneurysms with challenging locations and configurations.

AB - Background: In this video abstract, we present an unedited microsurgical resection of a fourth ventricular ependymoma performed by a senior author (JH). Currently, the goal of a standard treatment of a fourth ventricular ependymoma is based on microsurgical resection followed by radiochemotherapy. Our aim is to demonstrate the efficiency and safety of our microsurgical technique in deep brain territories under the principle "simple, clean, and preserving the normal anatomy." For this, a midline suboccipital approach and a proper praying sitting position are essential. Case Description: The patient is placed in a sitting praying position. After a midline suboccipital craniotomy, the ependymoma is accessed through telovelar approach. Partial debulking of the tumor follows careful separation of cerebellar tonsils; later, cautious dissection along the borderline of the tumor is performed. The cranial border of the lesion is accessed and the superior limit of the fourth ventricle and aqueduct is reached. Vascular feeders of the tumor coming from both posterior inferior cerebellar arteries are coagulated and cut. After careful dissection and devascularization of the lesion, the ependymoma is pulled out using soft and continuous traction with long ring microforceps. The final steps include inspection of remnants into the fourth ventricle with an appropriate orientation of the microscope toward the aqueduct and both foramina of Luschka. Conclusion: We believe this unedited video will provide us all small and big details that a neurosurgeon like a senior author JH takes into consideration when performing an efficient and safe surgery into the fourth ventricle, under the principle "simple, clean, and preserving the normal anatomy surgery."

PMID- 30283720 TI - Prosthetic material degeneration over time as a possible factor in delayed recurrence of hemifacial spasm after successful microvascular decompression. AB - Background: The effectiveness of microvascular decompression in treating hemifacial spasm is widely accepted. However, some experience recurrence of hemifacial spasm after successful decompression surgery. Especially, delayed recurrence more than 5 years after surgery is rare and the cause of this phenomenon is unknown. Case Description: A female underwent microvascular decompression to treat her hemifacial spasm 6 years ago. Six years later, her hemifacial spasm recurred and she underwent a second surgery. The second surgery revealed that the sponge had become fragile, losing the ability to absorb the impact of pulsatile compression of the offending artery on the root exit zone of her facial nerve. Conclusion: We report a case in which degeneration of material, a sponge (polyurethane), used in decompression surgery caused delayed recurrence of hemifacial spasm. The selection of appropriate prosthetic materials is essential in such functional surgeries. PMID- 30283721 TI - Timely Identification of Pregnancy in Noncommunicating Horn of Unicornuate Uterus by Three-Dimensional Transvaginal Ultrasonography. AB - Pregnancy in the rudimentary horn of a unicornuate uterus is uncommon and needs to be diagnosed at early stages to avoid uterine rupture to avert the high morbidity and mortality. In this case report, we discussed the advantage of three dimensional transvaginal ultrasonography (3D TV-USG) in assessing the early pregnancy in the noncommunicating rudimentary horn of uterus. A 23-year-old woman approached us for routine pregnancy scan. The location of 5-week pregnancy was confirmed in the right noncommunicating horn of a unicornuate uterus by 3D TV USG. She has undergone laparohysteroscopy, and excision of a gravid rudimentary horn was done. After an interval of 6 months, the patient received fertility treatment and conceived consequently. Although magnetic resonance imaging (MRI) is an excellent way of diagnosing uterine anomalies, the procedure is expensive, time-consuming, and not widely available. 3D USG is less expensive and more readily accessible for early diagnosis of uterine anomalies, particularly in health-care centers where MRI is not readily available or affordable. PMID- 30283722 TI - Monitoring Iron Overload: Relationship between R2* Relaxometry of the Liver and Serum Ferritin under Different Therapies. AB - Objective: The objective of this study was to evaluate the relationship between hepatic magnetic resonance imaging (MRI) with R2* relaxometry and serum ferritin in therapy monitoring of patients with iron overload. Further, a possible influence of the chosen therapy (phlebotomy or chelation) was assessed. Materials and Methods: We retrospectively evaluated 42 patients with baseline and follow-up R2* relaxometry and determination of serum ferritin before and during therapeutic phlebotomy or iron chelation therapy or watchful waiting, respectively. Linear regression analysis was used to analyze the correlation between changes of R2* and serum ferritin. Regression lines for different groups were compared with analysis of covariance. Results: We found a moderate positive statistical correlation (r = 0.509) between serum ferritin and R2*, a moderate positive correlation between absolute R2* changes and serum ferritin changes (r = 0.497), and a strong correlation for percentage changes (r = 0.712). The correlation analysis between relative changes of R2* and serum ferritin for the different therapies resulted in a strong correlation between phlebotomy and chelation (r = 0.855/0.727) and a moderate for no applied therapy (r = 0.536). In 22/92 paired examinations, a discordance of R2* and ferritin was found, particularly involving patients under chelation. Conclusions: Despite the good correlation between serum ferritin and R2* relaxometry in monitoring iron overload, treatment response may be misinterpreted when only serum ferritin is considered. Although ferritin is an acceptable and far cheaper tool for monitoring, MRI should be performed for confirmation, especially in case of unexpected ferritin changes, particularly under chelation therapy. PMID- 30283723 TI - Caliber-Persistent Labial Artery: A Report of a Rarely Recognized Lip Swelling. AB - Calibre-persistent labial artery (CPLA) is a commonly underdiagnosed vascular lesion of the lip. CPLA is an arterial branch that penetrates the submucosal tissue without loss of calibre. Clinical diagnosis is significant as misdiagnosis can lead to profuse haemorrhage following an excisional biopsy or surgical excision. Colour Doppler ultrasonography is a safe and non-invasive diagnostic tool to confirm the diagnosis. Here, we report a case of a 24-year-old man who complained of an asymptomatic pulsating non-progressive nodule on the left side of upper lip initially diagnosed as peripheral angiomatous lesion. Diagnosis was confirmed by high-resolution Colour Doppler Ultrasonography. The purpose of this case report is to highlight the clinical importance and diagnosis of a rarely reported soft tissue swelling of the lip to the attention of clinicians. PMID- 30283725 TI - REFINING A SUMMER BIOMEDICAL RESEARCH TRAINING PROGRAM FOR AMERICAN INDIAN AND ALASKA NATIVE (AIAN) STUDENTS. AB - Literature shows that students who enter the science, technology, engineering, mathematics, and medical-related (STEMM) pipeline at earlier stages of their career are more likely to be successful. This is especially true for underrepresented and economically disadvantaged students. Despite the increasing number of students entering the pipeline, American Indian and Alaska Native (AIAN) students still have a higher attrition rate compared to other ethnic groups. Educators and government agencies have worked to improve the success rate for AIAN students across all levels and fields by developing various programs aimed at training and mentorship. In 2007, the National Institute of Neurological Disorders and Stroke (NINDS) of the National Institutes of Health (NIH) in Bethesda, MD, increased their outreach efforts for recruiting AIAN students for the summer internship program. Our goal was to develop a culturally tailored research-training program that could recruit and retain AIAN students into STEMM degrees and careers. We adapted an existing program that provides training in biomedical science and mentorship at an NINDS research laboratory. From 2007 to 2016, of the 41 AIAN interns who participated, 35 (85%) remained in STEMM fields. Five interns obtained post baccalaureate positions at NIH and four entered graduate or medical school. These successful outcomes were brought about only after navigating myriad obstacles. We identified obstacles for AIAN student participation, and made adaptations to the summer internship. We made design decisions regarding recruitment, feasibility, lab placement and mentorship, supporting research and social networking, and sustaining AIAN culture. This design case highlights the obstacles and strategies for success that we developed. PMID- 30283724 TI - Diagnosis of sepsis from a drop of blood by measurement of spontaneous neutrophil motility in a microfluidic assay. AB - Current methods for the diagnosis of sepsis have insufficient precision, causing regular misdiagnoses. Microbiological tests can help diagnose sepsis but are usually too slow to have an impact on timely clinical-decision making. Neutrophils have high sensitivity to infections, yet measurements of neutrophil surface markers, genomic changes, and phenotype alterations have had only a marginal effect on sepsis diagnosis. Here, we report a microfluidic assay that measures the spontaneous motility of neutrophils in the context of plasma, in one droplet of blood. We measured the performance of the assay in two independent cohorts of critically ill patients suspected of sepsis. In the first cohort, we developed a machine-learning-based scoring system (sepsis score) that segregated patients with sepsis from those without sepsis. In the second cohort, we validated the sepsis score in a double-blinded, prospective case-control study. For the 42 patients across the two cohorts, the assay identified sepsis patients with 97% sensitivity and 98% specificity. The neutrophil assay could potentially be used to accurately diagnose and monitor sepsis in larger populations of at risk patients. PMID- 30283726 TI - Large Cohort Data Based Group or Community Disease Prevention Design Strategy: Strong Heart Study. AB - Background and Objective: A multitude of large cohort studies have data on incidence rates and predictors of various chronic diseases. However, approaches for utilization of these costly collected data and translation of these valuable results to inform and guide clinical disease prevention practice are not well developed. In this paper we proposed a novel conceptual group/community disease prevention design strategy based on large cohort study data. Methods and Results: The data from participants (n = 3516; 2056 women) aged 45 to 74 years and the diabetes risk prediction model from Strong Heart Study were used. The Strong Heart Study is a population-based cohort study of cardiovascular disease and its risk factors in American Indians. A conceptual group/community disease prevention design strategy based on large cohort data was initiated. The application of the proposed strategy for group diabetes prevention was illustrated. Discussion: The strategy may provide reasonable solutions to the prevention design issues. These issues include complex associations of a disease with its combined and correlated risk factors, individual differences, choosing intervention risk factors and setting their appropriate, attainable, gradual and adaptive goal levels for different subgroups, and assessing effectiveness of the prevention program. Conclusions: The strategy and methods shown in the illustration example can be analogously adopted and applied for other diseases preventions. The proposed strategy for a target group/community in a population provides a way to translate and apply epidemiological study results to clinical disease prevention practice. PMID- 30283727 TI - Aspects of Data Ethics in a Changing World: Where Are We Now? AB - Ready data availability, cheap storage capacity, and powerful tools for extracting information from data have the potential to significantly enhance the human condition. However, as with all advanced technologies, this comes with the potential for misuse. Ethical oversight and constraints are needed to ensure that an appropriate balance is reached. Ethical issues involving data may be more challenging than the ethical challenges of some other advanced technologies partly because data and data science are ubiquitous, having the potential to impact all aspects of life, and partly because of their intrinsic complexity. We explore the nature of data, personal data, data ownership, consent and purpose of use, trustworthiness of data as well as of algorithms and of those using the data, and matters of privacy and confidentiality. A checklist is given of topics that need to be considered. PMID- 30283728 TI - Data-Driven Investment Strategies for Peer-to-Peer Lending: A Case Study for Teaching Data Science. AB - We develop a number of data-driven investment strategies that demonstrate how machine learning and data analytics can be used to guide investments in peer-to peer loans. We detail the process starting with the acquisition of (real) data from a peer-to-peer lending platform all the way to the development and evaluation of investment strategies based on a variety of approaches. We focus heavily on how to apply and evaluate the data science methods, and resulting strategies, in a real-world business setting. The material presented in this article can be used by instructors who teach data science courses, at the undergraduate or graduate levels. Importantly, we go beyond just evaluating predictive performance of models, to assess how well the strategies would actually perform, using real, publicly available data. Our treatment is comprehensive and ranges from qualitative to technical, but is also modular-which gives instructors the flexibility to focus on specific parts of the case, depending on the topics they want to cover. The learning concepts include the following: data cleaning and ingestion, classification/probability estimation modeling, regression modeling, analytical engineering, calibration curves, data leakage, evaluation of model performance, basic portfolio optimization, evaluation of investment strategies, and using Python for data science. PMID- 30283729 TI - Electronic Health Record-Based Screening for Substance Abuse. AB - Existing methods of screening for substance abuse (standardized questionnaires or clinician's simply asking) have proven difficult to initiate and maintain in primary care settings. This article reports on how predictive modeling can be used to screen for substance abuse using extant data in electronic health records (EHRs). We relied on data available through Veterans Affairs Informatics and Computing Infrastructure (VINCI) for the years 2006 through 2016. We focused on 4,681,809 veterans who had at least two primary care visits; 829,827 of whom had a hospitalization. Data included 699 million outpatient and 17 million inpatient records. The dependent variable was substance abuse as identified from 89 diagnostic codes using the Agency for Healthcare Quality and Research classification of diseases. In addition, we included the diagnostic codes used for identification of prescription abuse. The independent variables were 10,292 inpatient and 13,512 outpatient diagnoses, plus 71 dummy variables measuring age at different years between 20 and 90 years. A modified naive Bayes model was used to aggregate the risk across predictors. The accuracy of the predictions was examined using area under the receiver operating characteristic (AROC) curve in 20% of data, randomly set aside for the evaluation. Many physical/mental illnesses were associated with substance abuse. These associations supported findings reported in the literature regarding the impact of substance abuse on various diseases and vice versa. In randomly set-aside validation data, the model accurately predicted substance abuse for inpatient (AROC = 0.884), outpatient (AROC = 0.825), and combined inpatient and outpatient (AROC = 0.840) data. If one excludes information available after substance abuse is known, the cross validated AROC remained high, 0.822 for inpatient and 0.817 for outpatient data. Data within EHRs can be used to detect existing or predict potential future substance abuse.

AB - Background: Opiate-based pain medications may incur adverse effects following bariatric surgery. The aim of this study was to evaluate the efficacy of intravenous Acetaminophen (IVAPAP) on length of stay (LOS) after laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery. Methods: This was a prospective, double blind, randomized controlled trial conducted from October 2011 to March 2014 at a 416-bed teaching hospital. Eighty-nine total patients were included (control group, n = 45; treatment group, n = 44). Patients were administered either 1000 mg of IVAPAP or placebo every 6 h beginning preoperatively and continuing for four doses. LOS, total narcotic consumption, pain and nausea scores, time to return of flatus (ROF), and postoperative rescue pain medication used were measured during the first 24 h after surgery. Results: LOS was significantly decreased in the treatment group compared with control (2.72 days vs. 3.18 days; p = 0.03). There was significant reduction in time to ROF (1.87 days vs. 2.24 days; p = 0.04). Pain was significantly decreased in the first 2 postoperative hours in the treatment group (p = 0.02). Total opioid consumption, postoperative nausea scores, and use of rescue pain medications were not affected. Conclusions: The use of IVAPAP significantly decreases LOS following LRYGB, improves acute postoperative pain control, and mediates quicker return of bowel function.

PMID- 30283732 TI - KRAS RENAISSANCE(S) in Tumor Infiltrating B Cells in Pancreatic Cancer. AB - KRAS is a driver mutation for malignant transformation. It is found in 30% of all cancers and in 90% of pancreatic cancers. The identification of small molecules selectively inhibiting KRAS mutants has been challenging, yet mutant KRAS has recently been shown to be targeted by tumor-infiltrating lymphocyte (TIL)-derived T cells that confer tumor regression upon adoptive transfer. Furthermore, a human IgG1 monoclonal antibody interfering with mutant KRAS function inside the cell has been described to inhibit growth of KRAS-mutant xenografts in tumor-bearing mice. B cells have been described to infiltrate pancreatic cancer and may be associated with tertiary lymphoid structures associated with good prognosis, or, in contrast, promote tumor growth. However, their function, nor their antigen specificity has been clearly defined. We discuss here the presence of tumor infiltrating B cells (TIB) in patients with pancreatic cancer that produce KRAS mutant specific IgG, underlining that intratumoral T and B cells may exclusively target mutant KRAS. KRAS-specific IgG may, therefore, serve as a readout of the activation of both arms of the anti-tumor adaptive immune armament although some B-cell populations may promote tumor progression. PMID- 30283734 TI - Reflections on the Management of Graves' Hyperthyroidism. PMID- 30283733 TI - Tumor-Intrinsic PD-L1 Signaling in Cancer Initiation, Development and Treatment: Beyond Immune Evasion. AB - Although the role of PD-L1 in suppressing the anti-tumor immune response is extensively documented, recent discoveries indicate a distinct tumor-intrinsic role for PD-L1 in modulating epithelial-to-mesenchymal transition (EMT), cancer stem cell (CSC)-like phenotype, metastasis and resistance to therapy. In this review, we will focus on the newly discovered functions of PD-L1 in the regulation of cancer development, describe underlying molecular mechanisms responsible for PD-L1 upregulation and discuss current insights into novel components of PD-L1 signaling. Furthermore, we summarize our current understanding of the link between PD-L1 signaling and the EMT program as well as the CSC state. Tumor cell-intrinsic PD-L1 clearly contributes to cancer stemness, EMT, tumor invasion and chemoresistance in multiple tumor types. Conversely, activation of OCT4 signaling and upregulation of EMT inducer ZEB1 induce PD-L1 expression in cancer cells, thereby suggesting a possible immune evasion mechanism employed by cancer stem cells during metastasis. Our meta-analysis demonstrated that PD-L1 is co-amplified along with MYC, SOX2, N-cadherin and SNAI1 in the TCGA endometrial and ovarian cancer datasets. Further identification of immune-independent PD-L1 functions and characterization of crucial signaling events upstream or downstream of PD-L1 in diverse cancer types and specific cancer subtypes, would provide additional targets and new therapeutic approaches. PMID- 30283736 TI - Thyroid Hemiagenesis in a Thyroiditis Prone Mouse Strain. AB - Background: Thyroid hemiagenesis, a rare congenital condition detected by ultrasound screening of the neck, is usually not manifested clinically in humans. This condition has been reported in mice with hypothyroidism associated with induced deficiency in paired box 8 and NK2 homeobox 1, sonic hedgehog, or T-box 1. Unexpectedly, we observed thyroid hemiagenesis in NOD.H2h4 mice, an unusual strain that spontaneously develops iodide enhanced thyroid autoimmunity but remains euthyroid. Objectives and Methods: First, to compare mice with thyroid hemiagenesis versus bilobed littermates for serum T4, autoantibodies to thyroglobulin (ELISA) and thyroid peroxidase (TPO; flow cytometry with eukaryotic cells expressing mouse TPO), gross anatomy, and thyroid histology; second, to estimate the percentage of mice with thyroid hemiagenesis in the NOD.H2h4 mice we have studied over 6 years. Results: Thyroid hemiagenesis was observed in 3 of 1,025 NOD.H2h4 mice (2 females, 1 male; 0.3$). Two instances of hemiagenesis were in wild-type females and one in a transgenic male expressing the human TSHR A subunit in the thyroid. Two mice had very large unilobed glands, as in some human cases with this condition. Thyroid lymphocytic infiltration, serum T4, and the levels of thyroid autoantibodies were similar in mice with thyroid hemiagenesis and bilobed littermates. Conclusions: Unlike hypothyroidism associated with hemiagenesis in transcription factor knockout mice, hemiagenesis in euthyroid NOD.H2h4 mice occurs spontaneously and is phenotypically similar to that occasionally observed in humans. PMID- 30283738 TI - The Krakow Declaration on Iodine: Tasks and Responsibilities for Prevention Programs Targeting Iodine Deficiency Disorders. AB - On April 18, 2018 the EUthyroid consortium released the Krakow Declaration on Iodine in response to the increasing concern about the deteriorating commitment of policymakers to address public health strategies against iodine deficiency disorders (IDD) in the European populations. Regulators and policymakers should harmonize obligatory Universal Salt Iodization to ensure free trade of fortified foodstuffs in Europe. Similarly, iodized animal feed requires regulatory approval to ensure free trade within the EU. National governments and public health authorities have to perform harmonized monitoring and evaluation of fortification programs at regular intervals to ensure optimal iodine supply to the population. Scientists, together with public health care workers, patient organizations, industry, and the public should support measures necessary to ensure that IDD prevention programs are sustainable, as appropriate within a rapidly changing environment and further social awareness of the issue.

AB - Background: Iodine deficiency disorders (IDD) represent a global health threat to individuals and societies. IDD prevention programmes have been introduced in many parts of the world. However, challenges remain, particularly in Europe due to fragmentation and diversity of approaches that are not harmonized. Objectives: This review is dedicated to the public-health impact of IDD prevention programmes. It sums up experiences collected by the EUthyroid consortium so far and provides information on stakeholders that should be involved in actions directed to improve the impact of IDD prevention. Methods: A joint European database for combining registry-based outcome and monitoring data as well as tools for harmonizing study methods were established. Methods for analyzing thyroglobulin from a dried blood spot are available for assessing the iodine status in the general population and at-risk groups. Mother-child cohorts are used for in-depth analysis of the potential impact of mild-to-moderate iodine deficiency on the neurocognitive development of the offspring. A decision analytic model has been developed to evaluate the long-term effectiveness and cost effectiveness of IDD prevention programmes. Results: EUthyroid has produced tools and infrastructure to improve the quality of IDD monitoring and follows a dissemination strategy targeting policymakers and the general public. There are tight connections to major stakeholders in the field of IDD monitoring and prevention. Conclusions: EUthyroid has taken steps towards achieving a euthyroid Europe. Our challenge is to inspire a greater sense of urgency in both policymakers and the wider public to address this remediable deficit caused by IDD. PMID- 30283735 TI - 2018 European Thyroid Association Guideline for the Management of Graves' Hyperthyroidism. AB - Graves' disease (GD) is a systemic autoimmune disorder characterized by the infiltration of thyroid antigen-specific T cells into thyroid-stimulating hormone receptor (TSH-R)-expressing tissues. Stimulatory autoantibodies (Ab) in GD activate the TSH-R leading to thyroid hyperplasia and unregulated thyroid hormone production and secretion. Diagnosis of GD is straightforward in a patient with biochemically confirmed thyrotoxicosis, positive TSH-R-Ab, a hypervascular and hypoechoic thyroid gland (ultrasound), and associated orbitopathy. In GD, measurement of TSH-R-Ab is recommended for an accurate diagnosis/differential diagnosis, prior to stopping antithyroid drug (ATD) treatment and during pregnancy. Graves' hyperthyroidism is treated by decreasing thyroid hormone synthesis with the use of ATD, or by reducing the amount of thyroid tissue with radioactive iodine (RAI) treatment or total thyroidectomy. Patients with newly diagnosed Graves' hyperthyroidism are usually medically treated for 12-18 months with methimazole (MMI) as the preferred drug. In children with GD, a 24- to 36 month course of MMI is recommended. Patients with persistently high TSH-R-Ab at 12-18 months can continue MMI treatment, repeating the TSH-R-Ab measurement after an additional 12 months, or opt for therapy with RAI or thyroidectomy. Women treated with MMI should be switched to propylthiouracil when planning pregnancy and during the first trimester of pregnancy. If a patient relapses after completing a course of ATD, definitive treatment is recommended; however, continued long-term low-dose MMI can be considered. Thyroidectomy should be performed by an experienced high-volume thyroid surgeon. RAI is contraindicated in Graves' patients with active/severe orbitopathy, and steroid prophylaxis is warranted in Graves' patients with mild/active orbitopathy receiving RAI. PMID- 30283739 TI - Can Suspicious Ultrasound Features Predict BRAFV600E Status in Papillary Thyroid Cancer? AB - Background: Papillary thyroid carcinoma (PTC) can be predicted from certain suspicious ultrasound (US) features of thyroid nodules. The aim of this study was to examine if these suspicious features can predict the more aggressive PTC associated with B-type Raf kinase (BRAFV600E) mutation. Methods: This was a retrospective review of prospectively collected data on patients with PTC and known BRAFV600E status. All patients underwent preoperative US by the same surgeon who performed all the operations. We divided patients into BRAFV600E positive and negative groups. All ultrasonographic data were collected including nodule size, echogenicity, solid or cystic nature, presence of calcifications, irregular margins, and internal vascularity. Results: Of 141 patients with PTC, BRAFV600E mutation was detected in 48 (34.0$) patients. There was no significant difference in nodule size (2.06 cm +/- 1.37 vs. 2.15 cm +/-1.55, p = 0.75) between BRAFV600E positive and negative groups. BRAFV600E positivity was associated with higher rates of -hypoechogenicity (57.5$ vs. 36.6, p = 0.02), calcifications (48.9 vs. 19.4$, p < 0.01), and irregular margins (21.3 vs. 6.5$, p < 0.01). There was no significant difference in the noncystic nature or internal vascularity between BRAFV600E positive and negative groups. The presence of all suspicious US features is associated with a positive predictive value of 100.0$. In the absence of all suspicious features, the negative predictive value was 84.2$. When suspicious lymph nodes (LNs) detected by preoperative US were compared, there was no significant difference between BRAFV600E positive and negative groups (30.6 vs. 21.7$, p = 0.35). Conclusion: The presence of multiple suspicious US findings of thyroid nodules can predict the BRAFV600E mutation status of papillary thyroid cancer nodules. The highest accuracy overall (93.2$) was achieved by combining calcification, irregular margins, and hypoechogenicity with extrathyroidal extension and LN metastasis. Future multi-institutional studies are warranted to help surgeons with risk stratification and operative planning for patients with papillary thyroid cancer. PMID- 30283740 TI - Prognostic Value of Stimulated Thyroglobulin Levels at the Time of Radioiodine Administration in Differentiated Thyroid Cancer. AB - Objective: The prognostic value of stimulated thyroglobulin (sTg) and Tg-related parameters prior to and immediately after radioactive iodine (RAI) administration was assessed in a cohort of patients presenting with differentiated thyroid cancer (DTC) as a predictor of recurrent or progressive structural disease. Methods: Clinical records of 180 DTC patients were retrospectively reviewed, and serum TSH, Tg, and Tg antibodies were recorded just before RAI administration (pre-) and at the time of whole body scanning (post-). Based on the results of initial staging and RAI scintigraphy, patients were divided into two groups: those who were considered to be structurally disease-free after thyroidectomy and RAI (group 1) and those who were not (group 2). Univariate analyses were performed for pre-Tg, ratioTg (post-Tg/pre-Tg), and other clinical and pathological markers for long-term outcome, as well as separate bivariate analyses focusing on pre-Tg to correct for possible confounders. Different pre-Tg cut-off values for predicting structural disease recurrence were assessed in a subgroup of patients in group 1 prepared with thyroid hormone withdrawal. Results: In group 1, (n = 166) male gender, higher T-stage and both Tg-related parameters proved to be significant risk factors for structural disease relapse. Of all candidate variables, only higher T-stage served to predict progressive structural disease in group 2 (n = 14). Subgroup analysis showed a negative predictive value of 91.67$ for pre-Tg < 10 ug/L. Conclusion: The sTg value at the time of RAI administration may be helpful in predicting structural disease recurrence in patients with DTC. PMID- 30283741 TI - Low-Dose Radioiodine Ablation in Patients with Low-Risk Differentiated Thyroid Cancer. AB - Aim: Based on the response criteria of the 2015 American Thyroid Associations guidelines, our objectives were to -determine the response rate when using a low dose of -131-I GBq in patients with low-risk differentiated thyroid cancer (LRDTC) and the influence of clinical and analytical variables on the prediction of complete response. Methods: We performed a multicentre and longitudinal study, including patients who were operated for LRDTC and who underwent radioiodine remnant ablation with a low-dose of 131-I. All patients were assessed at 6-12 months, and their status was classified as complete (excellent response) or incomplete response (structural incomplete, biochemical incomplete or indeterminate response). Various factors including age, gender, histology, tumour focality and size, stage, time from surgery to treatment, type of thyroid stimulating hormone (TSH) stimulation, preablation serum thyroglobulin (pTg), antiTg antibodies (pAntiTgAb) and TSH (pTSH) levels were also analysed in order to predict the complete response rate. Results: Of 108 patients, 79.6$ achieved complete response and the remaining showed incomplete response (2.9, 5.5 and 12$ due to biochemical incomplete, structural incomplete and indeterminate response respectively). Six patients received a new dose of 131-I. Tumour size and pAntiTgAb were the only factors related to therapeutic response (p = 0.03 and p < 0.01, respectively). However, pAntiTgAb was the only independent factor related to complete -response. Patients with complete response showed lower pTg than those with incomplete response (5.1 +/- 12.9 vs. 11.2 +/- 25 ng/mL) although without statistical significance (p = 0.14). There was no significant difference in the response rate depending on the thyrotropin stimulation methods. Conclusions: A low dose of 131-I was sufficient for reaching a complete response at 6-12 months of follow-up in the majority of patients with LRDTC. Tumour size and pAntiTgAb variables were related to therapeutic response. PMID- 30283743 TI - Reverse Epidemiology: An Experimental Framework to Drive Leishmania Biomarker Discovery in situ by Functional Genetic Screening Using Relevant Animal Models. AB - Leishmania biomarker discovery remains an important challenge that needs to be revisited in light of our increasing knowledge on parasite-specific biology, notably its genome instability. In the absence of classical transcriptional regulation in these early-branching eukaryotes, fluctuations in transcript abundance can be generated by gene and chromosome amplifications, which have been linked to parasite phenotypic variability with respect to virulence, tissue tropism, and drug resistance. Conducting in vitro evolutionary experiments to study mechanisms of Leishmania environmental adaptation, we recently validated the link between parasite genetic amplification and fitness gain, thus defining gene and chromosome copy number variations (CNVs) as important Leishmania biomarkers. These experiments also demonstrated that long-term Leishmania culture adaptation can strongly interfere with epidemiologically relevant, genetic signals, which challenges current protocols for biomarker discovery, all of which rely on in vitro expansion of clinical isolates. Here we propose an experimental framework independent of long-term culture termed "reverse" epidemiology, which applies established protocols for functional genetic screening of cosmid transfected parasites in animal models for the identification of clinically relevant genetic loci that then inform targeted field studies for their validation as Leishmania biomarkers. PMID- 30283742 TI - Non-vesicular Lipid Transport Machinery in Entamoeba histolytica. AB - Eukaryotic cells are organized into separate membrane-bound compartments that have specialized biochemical signature and function. Maintenance and regulation of distinct identity of each compartment is governed by the uneven distribution and intra-cellular movement of two essential biomolecules, lipids, and proteins. Non-vesicular lipid transport mediated by lipid transfer proteins plays a pivotal role in intra-cellular lipid trafficking and homeostasis whereas vesicular transport plays a central role in protein trafficking. Comparative study of lipid transport machinery in protist helps to better understand the pathogenesis and parasitism, and provides insight into eukaryotic evolution. Amebiasis, which is caused by Entamoeba histolytica, is one of the major enteric infections in humans, resulting in 40-100 thousand deaths annually. This protist has undergone remarkable alterations in the content and function of its sub-cellular compartments as well represented by its unique diversification of mitochondrion related organelle, mitosome. We conducted domain-based search on AmoebaDB coupled with bioinformatics analyses and identified 22 potential lipid transfer protein homologs in E. histolytica, which are grouped into several sub-classes. Such in silico analyses have demonstrated the existence of well-organized lipid transport machinery in this parasite. We summarized and discussed the conservation and unique features of the whole repertoire of lipid transport proteins in E. histolytica.

PMID- 30283745 TI - Mycobacterium tuberculosis Virulent Factor ESAT-6 Drives Macrophage Differentiation Toward the Pro-inflammatory M1 Phenotype and Subsequently Switches It to the Anti-inflammatory M2 Phenotype. AB - Tuberculosis, a human infectious disease caused by Mycobacterium tuberculosis (M.tb), is still a major cause of morbidity and mortality worldwide. The success of M.tb as a pathogen relies mainly on its ability to divert the host innate immune responses. One way by which M.tb maintains a persistent infection in a "silent" granuloma is to inhibit inflammation and induce an immunoregulatory phenotype in host macrophages (MPhis). However, M.tb effectors governing the switch of MPhis from the pro-inflammatory M1 to the anti-inflammatory M2 phenotype remain to be determined. The Early Secreted Antigenic Target 6 kDa or ESAT-6, has been implicated in the virulence and pathogenesis of tuberculosis. Here, we investigated roles of ESAT-6 in MPhi differentiation and polarization. We found that treatment of human monocytes with ESAT-6 did not interfere with differentiation of M1 MPhis. However, ESAT-6 promoted differentiation of M0 and M2 MPhis toward the M1 phenotype, as indicated by secretion of pro-inflammatory cytokines IL-6, IL-12, and TNF-alpha, and induction of a typical M1 transcriptional signature. Interestingly, we found that ESAT-6 switched terminal full activation of M1 polarized MPhis to the M2 phenotype. Indeed, in the pro inflammatory M1 MPhis, ESAT-6 was able to inhibit IL-12 and TNF-alpha secretion and stimulate that of IL-10. Moreover, gene expression profiling of these cells showed that ESAT-6 induced downregulation of M1 MPhi cell surface molecules CD80 and CD86, transcription factors IRF5 and c-MAF, cytokines IL-12, IL-10, and IL-6, as well as chemokines CXCL10 and CXCL1. Overall, our findings suggest ESAT-6 as being one of the effectors used by M.tb to induce the pro-inflammatory M1 phenotype at the primo-infection; a prerequisite step to promote granuloma formation and subsequently drive the phenotype switch of MPhi polarization from M1 to M2 at a later stage of the infection. Our study improves current knowledge regarding mechanisms of virulence of M.tb and may be helpful to develop novel tools targeting ESAT-6 for a better and more efficient treatment of tuberculosis. PMID- 30283744 TI - In Search of Biomarkers for Pathogenesis and Control of Leishmaniasis by Global Analyses of Leishmania-Infected Macrophages. AB - Leishmaniasis is a vector-borne, neglected tropical disease with a worldwide distribution that can present in a variety of clinical forms, depending on the parasite species and host genetic background. The pathogenesis of this disease remains far from being elucidated because the involvement of a complex immune response orchestrated by host cells significantly affects the clinical outcome. Among these cells, macrophages are the main host cells, produce cytokines and chemokines, thereby triggering events that contribute to the mediation of the host immune response and, subsequently, to the establishment of infection or, alternatively, disease control. There has been relatively limited commercial interest in developing new pharmaceutical compounds to treat leishmaniasis. Moreover, advances in the understanding of the underlying biology of Leishmania spp. have not translated into the development of effective new chemotherapeutic compounds. As a result, biomarkers as surrogate disease endpoints present several potential advantages to be used in the identification of targets capable of facilitating therapeutic interventions considered to ameliorate disease outcome. More recently, large-scale genomic and proteomic analyses have allowed the identification and characterization of the pathways involved in the infection process in both parasites and the host, and these analyses have been shown to be more effective than studying individual molecules to elucidate disease pathogenesis. RNA-seq and proteomics are large-scale approaches that characterize genes or proteins in a given cell line, tissue, or organism to provide a global and more integrated view of the myriad biological processes that occur within a cell than focusing on an individual gene or protein. Bioinformatics provides us with the means to computationally analyze and integrate the large volumes of data generated by high-throughput sequencing approaches. The integration of genomic expression and proteomic data offers a rich multi-dimensional analysis, despite the inherent technical and statistical challenges. We propose that these types of global analyses facilitate the identification, among a large number of genes and proteins, those that hold potential as biomarkers. The present review focuses on large-scale studies that have identified and evaluated relevant biomarkers in macrophages in response to Leishmania infection. PMID- 30283747 TI - Comparative Viral Sampling in the Sinonasal Passages; Different Viruses at Different Sites. AB - Background: With the emergence of the microbiome as an important factor in health and disease in the respiratory tract standardised, validated techniques are required for its accurate characterisation. No standardised technique has been reported specifically for viral sampling in the sinonasal passages. Aim: To optimise viral sampling techniques from the sinonasal cavity. Methods: Sterile cytology brushes were used under endoscopic guidance to sample the sinonasal mucosa at time of endoscopic sinus surgery at both the middle and inferior meatuses (MM and IM). DNA and RNA were extracted from the samples and underwent PCR or RT-PCR testing, respectively, for a panel of 15 common upper respiratory tract viruses. Results: Twenty-four adult patients were recruited for this study. 18/24 (75%) patients were positive for virus in at least one site, while 8/24 (33%) were positive for virus at both sites. The mean number of viruses identified at the two sites were similar (0.875 +/- 0.899 at the MM vs. 0.750 +/- 1.032 at the IM). 6/24 (25%) of patients showed no virus at either site, while 3/24 (12.5%) demonstrated the same viral species at both sites. Conclusion: Although the number of viruses present at different sites with the nasal cavity are similar, discord exists in the viral species between sites. It is therefore recommended that both sites are sampled in the clinical and research setting better to characterise the viral species within the nasal cavity. PMID- 30283748 TI - Correlation between B-Type Natriuretic Peptide and N-Terminal pro-B-Type Natriuretic Peptide in a Large Japanese Population at Risk of Stage A Heart Failure. AB - Background: The measurements of B-type natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) are useful for ruling out heart failure and as prognostic markers in not only heart failure populations but also general populations. It is not clear whether these two biomarkers are elevated in parallel or associated with demographic characteristics in large populations at risk of stage A heart failure. Here we investigated the relationship between BNP and NT-proBNP and extended the evaluation of this association to known demographic disparities in stage A heart failure. Methods: Of 4,310 ambulatory patients, we analyzed the cases of the 3,643 (mean age 65 +/- 11 years, 46$ male, and 79$ on antihypertensive medication) patients whose serum BNP and NT-proBNP levels were both measured and who had a history of and/or risk factors for cardiovascular disease from the Japan Morning Surge-Home Blood Pressure (J-HOP) Study dataset. Results: The median (25th-75th percentiles) BNP and NT-proBNP values were 18.7 (9.3-38.5) pg/mL and 50.3 (25.5-97.4) pg/mL. There was a significant association between log-transformed BNP and log-transformed NT-proBNP (r = 818, p < 0.001). A multiple linear regression analysis showed that log transformed NT-proBNP was significantly associated with log-transformed BNP (beta coefficient = 0.774, p < 0.001). When stratified by demographic characteristics, these associations remained (all p < 0.001). Conclusion: In a large Japanese population at risk of stage A heart failure, there was a significant association between BNP and NT-proBNP after adjustment and stratification by demographics. PMID- 30283749 TI - Evaluation of the Accuracy of a New Cuffless Magnetoplethysmography Blood Pressure Monitor in Hypertensive Patients. AB - Objective: There is a growing demand for cuffless blood pressure (BP) measurement as an easy alternative to cuff-occlusion-based BP measurement. We assessed the accuracy of a new cuffless, watch-style BP monitor with a magnetoplethysmography (MPG) sensor compared to two standard auscultatory and oscillatory BP monitors. Subjects and Methods: A total of 34 patients with uncontrolled hypertension (systolic BP >=150 mm Hg or diastolic BP >=95 mm Hg) were enrolled in the study. BP was measured by two conventional monitors and the new device during the pre exercise phase, during isometric handgrip exercise, and during the recovery phase (5 min after exercise). The correlation between monitors was assessed using intraclass correlation coefficient (ICC) and Bland-Altman plots. Results: Although two reference monitors produced highly correlated BP measurements, each was differentially correlated with BP measurements obtained by the new MPG monitor. During exercise, the mean difference between systolic BP obtained by the MPG and oscillatory monitors was >7 mm Hg with an ICC of 0.549 (95$ CI 0.264 0.746) in systole and 0.737 (95$ CI 0.534-0.859) in diastole. The ICC between the auscultatory monitor and the MPG monitor was 0.753 (95$ CI 0.559-0.868) in systole and 0.841 (95$ CI 0.706-0.918) in diastole after exercise. Bland-Altman plots also indicated that the performance of the new MPG device was very similar to that of the auscultatory monitor. Conclusion: Although the performance of the new MPG monitor was comparable to that of the reference monitors used in this study, improved stability and accuracy are necessary for accurate BP evaluation during dynamic activity. PMID- 30283750 TI - High-Intensity Statin Therapy Is "Too Much," Thus Not Indicated for Very Elderly Patients. AB - Purpose: Although moderate- to high-intensity statin therapy is increasingly recommended in cardiovascular disease patients, the efficacy and safety in elderly patients have not been proven clearly. Here, we compare the effect of various-intensity statins between elderly and very elderly patients. Methods: 43,870 patients over 65 years old who were treated with statins were screened using electronic medical record data. Results: We evaluated 451 patients in the elderly group aged 65-74 years and 159 patients in the very elderly group over 75 years old. Baseline cholesterol profiles were similar between the 2 groups, but the 10-year atherosclerotic cardiovascular disease (ASCVD) risk was significantly higher in the very elderly (20.9 +/- 11.5$ vs. 37.2 +/- 13.6$, p < 0.001). The reduction rate of low-density lipoprotein (LDL) (-40.2 +/- 21.3$ vs. -39.3 +/- 21.0$, p = 0.634) and the ratio of target LDL attainment (74.2 vs. 79.2$, p = 0.252) were similar between the 2 groups. Low-intensity statins showed comparable LDL cholesterol reduction with moderate-intensity statins both in the elderly and the very elderly groups. The 10-year ASCVD risk reduction was similar between the 2 groups (-3.5 +/- 4.9$ vs. -3.0 +/- 8.4$, p = 0.480), but in the very elderly group, no different ASCVD reduction rate was shown in low- to high-intensity statins (p = 0.784). Only the elderly group showed a significant correlation (r = 0.112, p = 0.017) with LDL reduction and 10-year ASCVD risk. Interestingly, the incidence of adverse drug reaction (ADR) was higher in the very elderly group (4.4$) than in the elderly group (2.7$) and was more frequent in high-intensity statin therapy. Conclusion: The efficacy of statins in LDL reduction was similar between the elderly and very elderly population. However, the benefit of moderate to high-intensity statins is limited considering potential ADR. Therefore, the stepwise intensification of statin therapy might be necessary for the very elderly in spite of the higher cardiovascular risk. PMID- 30283751 TI - Evaluation of Central Blood Pressure in an Asian Population: Comparison between Brachial Oscillometry and Radial Tonometry Methods. AB - Background: New devices have recently been developed using various features of the waveform derived from a brachial cuff for noninvasive estimation of central systolic blood pressure (SBP). Central SBP estimated from brachial oscillometry has never been compared with that estimated from radial tonometry in a Japanese population. Subjects and Methods: We recruited 155 Japanese volunteers (mean age 58 +/- 16 years, range 18-99 years; 66.5$ women) and estimated their central SBP using brachial oscillometry (Mobil-O-Graph) or radial tonometry (SphygmoCor). Results: The mean (standard deviation) peripheral SBP and central SBP measured with brachial oscillometry was 128 +/- 18 mm Hg and 118 +/- 16 mm Hg, respectively, while the central SBP estimated using radial tonometry was 119 +/- 18 mm Hg. The mean (standard deviation) difference in estimated central SBP between brachial oscillometry and radial tonometry was 0.36 +/- 5.9 mm Hg, and the central SBPs estimated using these devices were strongly correlated (r = 0.946, intraclass correlation coefficient = 0.940, p < 0.001). Conclusion: Central SBP estimated using brachial oscillometry was similar to that estimated from radial tonometry in a Japanese population. PMID- 30283752 TI - Obstructive Sleep Apnea Is Closely Related to Cardiovascular Risk Factors, but Not to Clinical Recurrence of Atrial Fibrillation after Catheter Ablation: An Analysis of Atrial Fibrillation Patients. AB - Background: Obstructive sleep apnea (OSA) is a well-known predictor of atrial fibrillation (AF). However, OSA usually accompanies other risk factors of AF. We tried to investigate whether OSA is related to AF recurrence after catheter ablation. Methods: A total of 378 patients (mean age 59.9 +/- 10.7 years, 72.5$ male) who underwent catheter ablation of AF were enrolled and underwent overnight ambulatory polysomnography before the ablation procedure. These patients were examined once every 3 months at the outpatient clinic to determine AF recurrence. Results: Based on the apnea-hypopnea index (AHI), we divided the study subjects into 3 groups defined as mild (AHI < 10), moderate (10 30) OSA. Patients with severe OSA had a higher prevalence of hypertension, diabetes mellitus, and coronary artery disease (CAD). However, AF recurrence was not different between the three groups. The Kaplan-Meier analysis also showed no significant difference in AF recurrence according to the degree of severity of OSA. Multivariate logistic regression analysis revealed that OSA might be a predictor of CAD; however, Cox regression analysis showed that only early recurrence is closely related to AF recurrence after catheter ablation, rather than the severity of OSA. Conclusion: This study shows that the severity of OSA is not associated with the recurrence of AF after catheter ablation in Korean patients. Treatment of OSA for the sole indication of lowering AF recurrence may need to be reconsidered. PMID- 30283754 TI - Dietary Sodium Intake and Serum Uric Acid: A Mini-Review. AB - The aim of the present review is to summarize recent studies on the relationship between dietary sodium intake and serum uric acid concentration. In short-term dietary sodium intervention studies, including a recent further analysis of a previously published trial, high dietary sodium intake (200 mmol/day), compared with a low sodium diet (20-60 mmol/day), resulted in a significant reduction in serum uric acid, being approximately 20-60 MUmol/L. This finding, though consistent across short-term studies, is in contradiction to the long-term observational evidence on the relationship between dietary sodium intake and serum uric acid. Indeed, in a population-based prospective study, high dietary sodium intake was associated with a higher serum uric acid concentration. If serum uric acid would be followed up, several currently ongoing long-term randomized dietary sodium intervention studies may shed some light on how dietary sodium intake interacts with serum uric acid in the development of hypertension. PMID- 30283753 TI - Methods of Blood Pressure Assessment Used in Milestone Hypertension Trials. AB - In the present review, we summarized the blood pressure (BP) measurement protocols of contemporary outcome trials in hypertension. In all these trials, clinic BP was used for the diagnosis and therapeutic monitoring of hypertension. In most trials, BP was measured in the sitting position with mercury sphygmomanometers or automated electronic BP monitors by trained observers. BP readings were taken on each occasion at least twice with a 30-to-60-s interval after 5 min of rest. Details regarding the arm side, cuff size, and the timing of BP measurement were infrequently reported. If clinic BP continues being used in future hypertension trials, the measurement should strictly follow current guidelines. The observers must be trained and experienced, and the device should be validated by automated electronic BP monitors. On each occasion, BP readings should be taken 2-3 times. The time interval between successive measurements has to be 30-60 s, and the resting period before the measurement should be at least 5 min in the supine or seated position and 1-3 min standing. BP should usually be measured in the seated position. The higher arm side and an appropriate size cuff should be chosen and noted. BP should be measured at defined trough hours. Automated office BP measurement has recently been used and seems to have less white-coat effect. The out-of-office BP measurement, either ambulatory or home BP monitoring, was only used in a subset of study participants of few hypertension trials. Future trials should consider these novel office or out-of-office BP measurements in guiding the therapy and preventing cardiovascular events. PMID- 30283755 TI - Effective Clinical Teaching Behaviors Views of Nursing Students and Nurse Educators at University of Gondar, Northwest Ethiopia: Cross-Sectional Institution Based Study. AB - Introduction: Clinical teaching behavior is a critical determinant for quality of clinical learning. Nursing students' and instructor's perception of effective clinical teaching behavior (ECTB) is important to modify and facilitate clinical education. Thus, the main purpose of this study was to assess the effective clinical teaching behavior (ECTB) as perceived by students and nursing instructors. Methods: Facility based cross-sectional descriptive study design was conducted among 178 participants. Data were collected using pre-tested and self administered questionnaire. Effective clinical teaching behaviors were measured by Nursing Clinical Teacher Effectiveness Inventory. Data were analyzed using descriptive and independent sample t-test. An adjusted odds ratio with 95% confidence interval computed to determine the level of significance. Results: The most important rated ECTB as perceived by students was teaching ability. For instructors, nursing competences was the most rated ECTB. The overall mean of ECTBs of the students and instructors were 4.26 (0.52) and 3.52 (0.74) respectively. There was statistically significant mean difference between them (t = 5.888). Conclusion: There was a statistically significant mean difference between the students' and instructors' perception of ECTBs. Thus, authors suggest nursing instructors to consider the presence of students who prefers different teaching methods. PMID- 30283756 TI - Experiences and Problems Encountered by Families of Children with Sickle Cell Anemia. AB - Introduction: Sickle Cell Anemia is a disease that has a high level of morbidity and early mortality for patients that are not followed and controlled properly. Study was conducted the aim of determining experiences and problems of families whose children with sickle cell anemia. Methods: Descriptive study was conducted the aim of determining experiences and problems of families (n= 206) whose children with sickle cell anemia. Before conducting this study, a written permission from the related institution and research ethics committee approval from Gaziantep University were obtained. Questionnaire is made up of two sections (10 questions), socio-demographic of families and data about their problems (15 questions and 11 statements). Data were evaluated SPSS (21.0), number and percentage calculations. Results: It was determined that 96.1% of participants knew nothing about disease before their children were diagnosed, 92.7% of them are aware the disease was genetically inherited, all participants were a disease carrier themselves, and 93.7% of them had no blood tests before marriage. 97.1% of participants have no support from their spouses, It was determined that 98.5% of children suffer from pain, 60.7% suffer from weakness 51.5% of the participants apply to hospitals to decrease the problems and 48.5% use medications at home. Conclusion: A great number of families have problems regarding fear of losing their children, lack of social aid and support. Majority of children suffer from pain, weakness, exhaustion, they stay at hospital between at least 1 and 5 times a year, they need blood transfusion. PMID- 30283757 TI - Evaluation of Children Quality of Life after Serous Otitis Media Surgery. AB - Introduction: Otitis media with effusion is a common childhood disease diagnosed with the accumulation of serous fluid or mucous in the middle ear. If not treated, the sustainable effusion leads to change and destruction of middle ear structures. One of the most successful treatment methods is myringotomy and ventilation tube insertion, which leads to improvement of patients' quality of life. The aim of this study was to evaluate children's quality of life after inserting ventilation tubes. Methods: This prospective cross-sectional study examined the quality of life of the children suffering from otitis media with sustainable effusion, who were candidates for ventilation tube insertion. Otitis Media outcome-22 (OMO -22) questionnaire, was used to record the patients' problems in a 12-week period before and after surgery. Results: In this study, 70 patients, including 43 (61.4%) boys and 27 (38.6%) girls (1y-13y), who completed the questionnaire, were studied. Treatment with ventilation tubes improved many physical symptoms of the hearing loss along with speech and behavioral symptoms. A significant reduction was observed in the number of physician visits and the use of antibiotics for ear problems. Conclusion: Ventilation tube insertion not only reduced the symptoms of otitis media with effusion, but also improved the children's quality of life. PMID- 30283759 TI - Social Support and Depression in Iranian Cancer Patients: the Role of Demographic Variables. AB - Introduction: Depression is the most frequent mental disorder in cancer patients, which is, unfortunately, less noticeable. Despite extensive researches, we only have scant knowledge about the influence of social support on depression in cancer patients. The aim of this study is to examine the relationship between perceived social support and depression and demographic variables on cancer patients. Methods: This is a descriptive correlational study on two hundred cancer patients in Isfahan, Iran. The study subjects were selected through convenient sampling method and data were collected using questionnaires (demographic questionnaire, Multidimensional Scale of Perceived Social Support (MSPSS) and Beck Depression Scale (BDS). Data were analyzed by SPSS software (Frequency distribution, Chi-Square and Spearman correlation). Results: The findings showed that social support and depression in cancer patients are significantly correlated with each other (r = - 0.785, P <0.001). Furthermore, the findings indicated that there are statistically significant correlations between degrees of education with depression and also between the numbers of children with social support and depression in cancer patients. For all analyses, was considered significant. Conclusion: In conclusion, we suggest that interventions to alleviate depression in cancer patients may be designed with consideration of demographic characteristics especially the level of education and the number of supporters of the patient to increase the quality of life in cancer patients and minimize the negative consequences of cancer diagnosis. PMID- 30283758 TI - The Effect of Fun Physical Activities on Sarcopenia Progression among Elderly Residents in Nursing Homes: a Randomized Controlled Trial. AB - Introduction: Immobilization in the elderly can reduce the size and strength of muscle mass and ultimately lead to sarcopenia, the severity and progression of which can be prevented by exercise. However, due to physical and mental conditions, the elderly may be unable to take full advantage of regular exercise. Therefore, fun exercise through motivation and effective participation of older adults is likely to have positive effects on decreasing the volume and power of muscle mass. The aim of this study was to determine the effect of fun physical activities on the progression of sarcopenia among elderly residents in nursing homes. Methods: This study was a two-group randomized controlled trial conducted in 2014. Sixty three older adults were recruited by the random sampling. The elderly in the fun physical exercise group did the exercise for 8 weeks, three times a week for 20 minutes at a time, and in the control group, the adults did the routine exercises. The Berg Balance Scale, a dynamometer, and the Six-Minute Walk Test were used to measure sarcopenia criteria (balance, muscle strength, distance traveled).The statistical analysis was done by SPSS version 13. Results: The results showed that the mean score of the sarcopenia criterion (balance, distance walked, muscles strength) was significantly increased in the fun physical exercise group than in the control group. Conclusion: The fun physical activity reduces sarcopenia progression through improving balance, increasing distances walked, and strengthening muscles. PMID- 30283760 TI - Improving Quality of Care in Hemodialysis: a Content Analysis. AB - Introduction: Hemodialysis is currently the most common alternative treatment in patients with renal failure in the world. Today, despite the support provided by healthcare providers for these patients, they still express dissatisfaction with the quality of care and find it inadequate. However, there have been few studies investigating the needs of in-patients receiving hemodialysis care in Iran. Thus this research was undertaken to study the needs and demands of such patients. Methods: This qualitative research was conducted from June to November 2016 to investigate the view points of the patients, their families and health care providers about improving quality of care in dialysis unit. At first, the sampling was based on a purposeful sampling method. A total of 35 participants (patients, their families and health care providers) were interviewed. The interviews were analyzed via Graneheim & Lundman qualitative content analysis. Results: Data analyses led to the production of 700 primary codes, 54 subcategories and 27 secondary categories out which 4 main categories of modification of physical stressors, requirement of support and the requirement of improved quality of Health Care service and improved facilities and equipment requirement. Conclusion: Planning for modification of physical stressors, improved support of patients, enhancing the quality of care services provided by the treatment team, upgrading the facilities and equipment and the adoption of an interdisciplinary approach are all believed to improve the care services among in patients receiving hemodialysis treatment. PMID- 30283761 TI - Service Quality Gaps in the Provision of Care to Surgical Patients: a Cross Sectional Study in the Northwest of Iran. AB - Introduction: The evaluation of service quality is a key measurement which provides the necessary information for effective decision making and providing high quality care. This study aimed to investigate the factors affecting the service quality gap for the provision of care from the perspective of surgical patients hospitalized in a teaching hospital in the Northwest of Iran in 2015. Methods: In this descriptive cross-sectional study a total of 300 patients and 101 nurses were selected by random sampling method. The data regarding patients' expectations and perceptions of the quality of healthcare services were collected using the SERVQUAL questionnaire. Also, the nurses' demographic data were assessed using the demographic data tool. Results: The mean and standard deviation of the patients' expectations and perceptions of the quality of healthcare services were 66.59)8.52) and 51.81(11.97), respectively. In all dimensions of the quality of healthcare services, the patients' perceptions were lower than their expectations. The greatest gap was observed in the dimensions of assurance and responsibility and the lowest gap was reported in the domains of reliability and empathy. There were statistically significant relationships between the nurses' age, work experiences in surgical wards, professional experiences of nurses, patients' income level and the gap in the quality of healthcare services. Conclusion: Despite great efforts directed at the field, the healthcare system still faces numerous challenges in the provision of high quality healthcare services to the patients. The health system should support low income people and employ professional and experienced nurses for improving the quality of healthcare services. PMID- 30283762 TI - The Resilient Care of Patients with Vegetative State at Home: a Grounded Theory. AB - Introduction: The care of patients in vegetative state at home is difficult because they need continuous medical interventions and extensive care. The present study aims to explain the process of home care of patients in vegetative state at home. Methods: This study was a qualitative research with a grounded theory approach. The participants were 22 people (included 17 family caregivers and 5 professional caregivers) who were enrolled in a purposive sampling. Data was gathered through unstructured interviews, observations and field notes. Data collection was continued to saturation. Data analysis was performed through the Strauss and Corbin 1998 approach. The MAXQDA10 software was used to facilitate data analysis. Results: The data analysis led to emerge four main concepts included "erosive care", "erosive expenditures", "seeking solver education" and "lasting hope" as the axes of the study. Participants' experiences showed that the main concern of family caregivers of vegetative patients was "playing an inevitable role in care", in which they did not hesitate to make any effort, and they tolerated all the problems and issues. Therefore, "resilient care" was extracted as the underlying idea of this study. Conclusion: The process of resilient care of vegetative patients at home showed planning by policy makers in health system is very important and underscored the necessity for supporting families and family caregivers of these patients. So some changes in the health system for this goal might include considering home care and supporting them in various aspects, especially information, financial and emotional dimensions. PMID- 30283763 TI - Delayed Cord Clamping Increased the Need for Phototherapy Treatment in Infants With AB0 Alloimmunization Born by Cesarean Section: A Retrospective Study. AB - Objective: To compare the effect of Delayed Cord Clamping (DCC) to Immediate Cord Clamping (ICC) on phototherapy treatment in a cohort of cesarean-delivered newborns with AB0-alloimmunization. Study Design: In a retrospective cohort study neonates with Gestational Age (GA) >= 35 weeks and diagnosed with AB0 alloimmunization before implementation of DCC (ICC group) were compared with neonates born after implementation (DCC group). The primary outcome was the need for phototherapy. Secondary outcomes included hospital stay, readmission rate, need for extra intravenous fluids, maximum bilirubin concentration, and hours of life at bilirubin peak. We used regression models to adjust for weight loss, type of feeding, birth weight, and gestational age. Results: In total 336 neonates were included, of which 192 neonates in the ICC group and 144 in the DCC group. There were no differences in basic characteristics between the two groups except for birth weight (ICC 3193 +/- 468 g vs. DCC 3053 +/- 446 g, p = 0.01) and GA (ICC 38.2 +/- 1 weeks of GA, vs. DCC 37.9 +/- 1 weeks of GA; p = 0.01). When adjusted for confounding factors, after implementation of DCC, significantly more infants with AB0 alloimmunization needed phototherapy (22.4% vs. 36.8%, RR 1.61 CI: 1.15-2.28; p = 0.006; Number Needed to Harm 7), needed to stay longer in hospital (20.3% vs. 30.5%, RR 1.53 CI: 1.05-2.23; p = 0.03). The maximum bilirubin was higher (11.4 +/- 4.0 mg/dl vs. 12.9 +/- 3.5 mg/dl, p < 0.001) and occurred later [74 (67-92) hours vs. 84 (70-103) hours; p = 0.04]. There was no difference in the need for intravenous fluids (1.6% vs. 4.9%; not significant) and readmissions (1.6% vs. 3.5%; not significant). Conclusion: Infants with AB0 alloimmunization needed more often phototherapy and were admitted longer after implementation of DCC policy. Further studies are needed to see whether the benefit of DCC outweighs the increased morbidity, admission days, and related hospital costs. PMID- 30283764 TI - Weight Loss Surgery Utilization in Patients Aged 14-25 With Severe Obesity Among Several Healthcare Institutions in the United States. AB - Introduction: Obesity is associated with early co-morbidities and higher mortality. Even though weight loss surgery (WLS) in adolescents with severe obesity reliably achieves safe and lasting improvement in BMI and superior resolution of comorbid diseases, its utilization among young patients in the clinical practice stands unclear. Objective: To show the prevalence of weight loss surgery utilization rates in adolescents and young adults among several healthcare institutions in the United States. Method: WLS in 14-25 years old between 2000 and 2017 was obtained from Washington University, Morehouse Medical, University of Texas, Wake Forest Baptist Medical Center, Beth Israel Deaconess Medical Center, Boston Children's Hospital, Boston Medical Center, and Partners Healthcare using the Shared Health Research Information Network (SHRINE) and Research Patient Data Registry (RPDR) web-based query tools. ICD-9 codes were used for bariatric surgery. Results: Among 2500635 individuals, 18008 (0.7%) had severe obesity. At Partners, 1879 patients had severe obesity, of which 404 (21.5%) underwent WLS, whereas at Washington University, 44 (2.5%) of 1788 the underwent WLS. 13 (2.3%) of the 575 at BIDMC, 43 (1.5%) of the 2969 at BMC, and 37 (0.4%) of 8908 at BCH underwent WLS (p < 0.0001 for all). Discussion: Even though WLS has shown to be the most effective treatment to create sustainable changes in metabolic derangements for moderate to severe obesity and its comorbidities, it has been underutilized. Further studies need to be conducted to ensure WLS is utilized for those patients who would achieve the most benefit. PMID- 30283765 TI - Indirect Calorimetry: History, Technology, and Application. AB - Measurement of energy expenditure is important in order to determine basal metabolic rate and inform energy prescription provided. Indirect calorimetry is the reference standard and clinically recommended means to measure energy expenditure. This article reviews the historical development, technical, and logistic challenges of indirect calorimetry measurement, and provides case examples for practicing clinicians. Formulae to estimate energy expenditure are highly inaccurate and reinforce the role of the indirect calorimetry and the importance of understanding the strength and limitation of the method and its application. PMID- 30283766 TI - The Relative Roles of Peer and Parent Predictors in Minor Adolescent Delinquency: Exploring Gender and Adolescent Phase Differences. AB - Social learning theories assume that delinquent peer norms and/or peer pressure are the components of delinquent peer socialization that lead to subsequent adolescent delinquency. However, these specific peer influences are rarely investigated. Moreover, social learning theories such as coercion theory posit that parenting behaviors also play an important role in the development or prevention of delinquency. However, surprisingly, little research has investigated whether parent behaviors could moderate the link between the above described peer influences and adolescent delinquency. Hence, using structural equation modeling, the current 1-year longitudinal study investigated these questions among ethnically-diverse Dutch adolescents (N = 602; M age = 13.50; 46.42% female at baseline), who were mostly between12 and 15 years old. Additionally, using multi-group models, and a stringent p-value of p < 0.01, we explored whether gender and adolescent phase (i.e., early versus middle adolescence) further moderated these links. The majority of the analyses, resulted in non-significant findings. Specifically, in our non-multi group model, we found no significant peer, and family effects for the entire sample. However, for our multi-group models, we found that higher levels of negative mother adolescent relationship quality exacerbated the link between peer pressure and subsequent early adolescent boys' delinquency 1 year later, while low levels of mother-adolescent negative relationship quality reversed the association. That is, low levels of mother-adolescent negative relationship quality attenuated the link from higher levels of peer pressure to higher levels of delinquency, but only in early adolescent boys. These findings existed above and beyond significant links from prior adolescent delinquency (T1) to future adolescent delinquency (T2). To conclude, although this was not the case for most adolescents, for early adolescent boys fewer negative interactions between mother and adolescents at an earlier time point (in advance) could potentially curtail the negative effects that delinquent peer pressure has on delinquency in the future. Implications for theory and practice are discussed. PMID- 30283767 TI - Effect of a Health Coach Intervention for the Management of Individuals With Type 2 Diabetes Mellitus in China: A Pragmatic Cluster Randomized Controlled Trial. AB - : Aim: To determine the effect of a health coach intervention for the management of glycemic control, as well as physiological, psychological and self-care outcomes of patients with type 2 diabetes mellitus (T2DM), compared with usual care. Methods: This pragmatic cluster RCT was conducted in the Fengtai district of Beijing from August 2011 to December 2013. Forty-one community health stations (CHSs) were cluster randomized (stratified geographically, 1:1 ratio) and eligible, randomly selected T2DM patients were sequentially contacted by CHSs. Control participants received usual care according to the Chinese Guideline for Diabetes Prevention and Management. Intervention participants received 18-months of health coaching based on principles of Motivational Interviewing (MI) plus usual care. Medical and pathology fees were waived for both groups. Outcome assessment was performed at baseline, 6, 12, and 18-months. The primary outcome was glycated hemoglobin (HbA1c); secondary outcomes encompassed a suite of physiological, psychological and self-care measures. Results: No differential treatment effect was found at 18-months for HbA1c (adj. difference -0.07, 95% CI 0.53 to 0.39, p = 0.769) or any specified secondary outcomes. Interestingly, both groups displayed a statistically and clinically significant within-group improvement of the same magnitude at 18-months for HbA1c (intervention: mean change -3.65, 95% CI -3.92 to -3.37; control: mean change -3.38, 95% CI -3.67 to 3.08). Conclusions: The lack of differential treatment effects observed indicate that it may be premature to recommend the routine delivery of health coach interventions based on MI principles for the management of T2DM in China. However, the large, comparable within-group improvement in mean HbA1c promotes the establishment of free, regular clinical health assessments for individuals with T2DM in China. TRIAL REGISTRATION: ISRCTN registry - ISRCTN01010526 (https://doi.org/10.1186/ISRCTN01010526). PMID- 30283768 TI - Field Epidemiology and Laboratory Training Program, Where Is the L-Track? AB - Background: Modifications of the Field Epidemiology Training Program (FETP) curricula to include a laboratory track (L-Track), to become Field Epidemiology and Laboratory Training Program (FELTP), began in 2004 in Kenya. The L-Track offered candidates training on laboratory competencies in management, policy, quality systems, and diagnostic methods as well as epidemiology, disease surveillance and outbreak response. Since then several FELTPs have discontinued the L-Track and instead offer all candidates, epidemiologists and laboratorians, a single FETP curriculum. Reasons for these changes are reported here. Methods: A questionnaire was sent to directors of 13 FELTP programs collecting information on the status of the programs, reasons for any changes, basic entry qualifications, source institutions and where residents were post enrollment or after graduation. Data from previous CDC internal assessments on FELTP L-Track was also reviewed. Results: Out of the 13 FELTPs included, directors from 10 FELTPs sent back information on their specific programs. The FELTPs in Kenya, Mozambique, Cameroon and Kazakhstan and Mali have discontinued a separate L-Track while those in Ghana, Georgia, Nigeria, Rwanda, and Tanzania continue to offer the separate L-Track. Reasons for discontinuation included lack of standardized curriculum, unclear strategies of the separate L-Track, and funding constraints. Two countries Kenya and Tanzania reported on the career progression of their graduates. Results show 84% (Kenya) and 51% (Tanzania) of candidates in the FELTP, L-Track were recruited from national/regional medical health laboratories. However post-graduation, 56% (Kenya) and 43% (Tanzania) were working as epidemiologists, program managers, program coordinators, or regulatory/inspection boards. Professional upward mobility was high; 87% (Kenya) and 73% (Tanzania) residents, reported promotions either in the same or in new institutions. Conclusions: The FELTP L-Track residents continue to offer critical contributions to public health workforce development with high upward mobility. While this may be a reflection of professional versatility and demand of the FELTP graduates, the move from core laboratory services underscores the challenges in filling and retaining qualified staff within the laboratory systems. Results suggest different strategies are needed to strengthen laboratory management and leadership programs with a clear focus on laboratory systems and laboratory networks to meet current and future clinical and public health laboratory workforce demands.

PMID- 30283770 TI - Porous NaTi2(PO4)3 Nanocubes Anchored on Porous Carbon Nanosheets for High Performance Sodium-Ion Batteries. AB - NaTi2(PO4)3 has attracted great interest as anode material for sodium ion batteries owing to its open three-dimensional framework structure and limited volume changes during the charge and discharge process. However, the poor intrinsic electronic conductivity of NaTi2(PO4)3 needs to be improved for high rate capability. In this work, porous NaTi2(PO4)3 nanocubes anchored on porous carbon nanosheets (NaTi2(PO4)3/C) are designed and developed. This material exhibits a large discharge capacity and good rate capacity including a first discharge capacity of 485 mAh g-1 at a current density of 0.1 A g-1, and 98 mAh g 1 retained at a high rate of 4 A g-1 even after 2,000 cycles. These results suggest that NaTi2(PO4)3/C is a promising anode material for sodium-ion batteries. PMID- 30283771 TI - Pickering Emulsions Electrostatically Stabilized by Cellulose Nanocrystals. AB - Cellulose Nanocrystals (CNC) are explored to stabilize oil/water emulsions for their ability to adsorb at the oil/water interface. In this work, the role of electrostatic forces in the CNC ability to stabilize oil/water emulsions is explored using canola oil/water and hexadecane/water as model systems. Canola oil/water and Hexadecane/ water (20/80, v/v) emulsions were stabilized with the addition of CNCs using ultrasonication. Emulsion droplet sizes range from 1 to 4 MUm as measured by optical microscopy. It is found that CNC can stabilize oil/water emulsions regardless of their charge density. However, reducing the surface charge density, by adding salts and varying pH, can reduce the amount of CNC's required to form a stable emulsion. Just by adding 3 mM Na+ or 1 mM or less Ca+2 to a CNC suspension, the amount of CNC reduced by 30% to stabilized 2 mL of Canola oil. On the other hand, adding salt increases the emulsion volume. The addition of 100 mM Na+ or the reduction of pH below 2 leads to the aggregation of CNC; emulsions formed under these conditions showed gel-like behavior. This work shows the potential of nanocellulose crystal in stabilizing food and industrial emulsions. This is of interest for applications where biodegradability, biocompatibility, and food grade requirements are needed.

AB - The silicon dioxide (SiO2)-coated bismuth vanadate (BiVO4) composites as visible driven-photocatalysts were successfully synthesized by the co-precipitation method. The effects of SiO2 coating on the structure, optical property, morphology and surface properties of the composites were investigated by X-ray diffraction (XRD), UV-visible diffuse reflectance spectroscopy (DRS), transmission electron microscopy (TEM) and Brunauer-Emmette-Teller (BET) measurements. The photocatalytic activity of monoclinic BiVO4 and BiVO4/SiO2 composites were evaluated according to the degradation of methylene blue (MB) dye aqueous solution under visible light irradiation. The SiO2-coated BiVO4 composites showed the enhancing photocatalytic activity approximately threefold in comparison with the single phase BiVO4. PMID- 30283772 TI - Small-Molecule Electron Acceptors for Efficient Non-fullerene Organic Solar Cells. AB - The development of organic electron acceptor materials is one of the key factors for realizing high performance organic solar cells. Compared to traditional fullerene acceptor materials, non-fullerene electron acceptors have attracted much attention due to their better optoelectronic tunabilities and lower cost as well as higher stability. Non-fullerene organic solar cells have recently experienced a rapid increase with power conversion efficiency of single-junction devices over 14% and a bit higher than 15% for tandem solar cells. In this review, two types of promising small-molecule electron acceptors are discussed: perylene diimide based acceptors and acceptor(A)-donor(D)-acceptor(A) fused-ring electron acceptors, focusing on the effects of structural modification on absorption, energy levels, aggregation and performances. We strongly believe that further development of non-fullerene electron acceptors will hold bright future for organic solar cells. PMID- 30283774 TI - The Impact of Cr3+ Doping on Temperature Sensitivity Modulation in Cr3+ Doped and Cr3+, Nd3+ Co-doped Y3Al5O12, Y3Al2Ga3O12, and Y3Ga5O12 Nanothermometers. AB - A new approach to enhance the sensitivity of transition metal ion based nanocrystalline luminescent thermometer is presented. It was shown that the increase of Cr3+ concentration in three types of garnet host namely Y3Al5O12, Y3Ga5O12, and Y3Al2Ga3O12 allows for significant enhancement of their performance in non-contact thermometry. This phenomenon is related to the weakening of the crystal field strength due to enlargement of average Cr3+-O2- distance at higher Cr3+ concentrations. By increasing Cr3+ concentration from 0.6 to 30%, the sensitivity increased by over one order of magnitude from S = 0.2%/ degrees C to S = 2.2%/ degrees C at 9 degrees C in Y3Al2Ga3O12 nanocrystals. Moreover, it was found that due to the Cr3+ -> Nd3+ energy transfer in the Cr3+, Nd3+ co-doped system, the usable Cr3+ concentration, for which its emission can be detected, is limited to 10% while the sensitivity at -50 degrees C was doubled (from 1.3%/ degrees C for Y3Al2Ga3O12:10%Cr3+ to 2.2%/ degrees C Y3Al2Ga3O12:10%Cr3+, 1%Nd3+ nanocrystals).

AB - The common chemical method to synthesize Phenolic Acids (PAs) involves a relatively considerable energy intake. In order to solve this issue, microwave assisted Knoevenagel-Doebner condensations were developed. Nevertheless, these synthetic procedures prove difficult to reproduce. Herein, we developed and optimized-by using a combination of a Design of Experiment and a standard optimization approach-a reliable procedure that converts naturally occuring p hydroxybenzaldehydes into the corresponding PAs with conversions of 86-99% and in 85-97% yields. PMID- 30283776 TI - Photocrosslinkable Gelatin Hydrogels Modulate the Production of the Major Pro inflammatory Cytokine, TNF-alpha, by Human Mononuclear Cells. AB - Hydrogels are an attractive class of biomaterials in tissue engineering due to their inherently compatible properties for cell culture. Gelatin methacryloyl (GelMA) has shown significant promise in the fields of tissue engineering and drug delivery, as its physical properties can be precisely tuned depending on the specific application. There is a growing appreciation for the interaction between biomaterials and cells of the immune system with the increasing usage of biomaterials for in vivo applications. Here, we addressed the current lack of information regarding the immune-modulatory properties of photocrosslinked GelMA. We investigated the ability of human mononuclear cells to mount inflammatory responses in the context of a GelMA hydrogel platform. Using lipopolysaccharide to stimulate a pro-inflammatory immune response, we found tumor necrosis factor alpha (TNF-alpha) expression was suppressed in GelMA culture conditions. Our findings have important implications on the future use of GelMA, and potentially similar hydrogels, and highlight the significance of investigating the potential immune-modulatory properties of biomaterials. PMID- 30283777 TI - An Efficient Modelling-Simulation-Analysis Workflow to Investigate Stump-Socket Interaction Using Patient-Specific, Three-Dimensional, Continuum-Mechanical, Finite Element Residual Limb Models. AB - The lack of an efficient modelling-simulation-analysis workflow for creating and utilising detailed subject-specific computational models is one of the key reasons why simulation-based approaches for analysing socket-stump interaction have not yet been successfully established. Herein, we propose a novel and efficient modelling-simulation-analysis workflow that uses commercial software for generating a detailed subject-specific, three-dimensional finite element model of an entire residual limb from Diffusion Tensor MRI images in <20 min. Moreover, to complete the modelling-simulation-analysis workflow, the generated subject-specific residual limb model is used within an implicit dynamic FE simulation of bipedal stance to predict the potential sites of deep tissue injury. For this purpose, a nonlinear hyperelastic, transversely isotropic skeletal muscle constitutive law containing a deep tissue injury model was implemented in LS-DYNA. To demonstrate the feasibility of the entire modelling simulation-analysis workflow and the fact that detailed, anatomically realistic, multi-muscle models are superior to state-of-the-art, fused-muscle models, an implicit dynamic FE analysis of 2-h bipedal stance is carried out. By analysing the potential volume of damaged muscle tissue after donning an optimally-fitted and a misfitted socket, i.e., a socket whose volume was isotropically shrunk by 10%, we were able to highlight the differences between the detailed individual- and fused-muscle models. The results of the bipedal stance simulation showed that peak stresses in the fused-muscle model were four times lower when compared to the multi-muscle model. The peak interface stress in the individual-muscle model, at the end of bipedal stance analysis, was 2.63 times lower than that in the deep tissues of the stump. At the end of the bipedal stance analysis using the misfitted socket, the fused-muscle model predicted that 7.65% of the residual limb volume was injured, while the detailed-model predicted 16.03%. The proposed approach is not only limited to modelling residual limbs but also has applications in predicting the impact of plastic surgery, for detailed forward dynamics simulations of normal musculoskeletal systems. PMID- 30283778 TI - Validating the RedMIT/GFP-LC3 Mouse Model by Studying Mitophagy in Autosomal Dominant Optic Atrophy Due to the OPA1Q285STOP Mutation. AB - Background: Autosomal dominant optic atrophy (ADOA) is usually caused by mutations in the essential gene, OPA1. This encodes a ubiquitous protein involved in mitochondrial dynamics, hence tissue specificity is not understood. Dysregulated mitophagy (mitochondria recycling) is implicated in ADOA, being increased in OPA1 patient fibroblasts. Furthermore, autophagy may be increased in retinal ganglion cells (RGCs) of the OPA1Q285STOP mouse model. Aims: We developed a mouse model for studying mitochondrial dynamics in order to investigate mitophagy in ADOA. Methods: We crossed the OPA1Q285STOP mouse with our RedMIT/GFP LC3 mouse, harboring red fluorescent mitochondria and green fluorescent autophagosomes. Colocalization between mitochondria and autophagosomes, the hallmark of mitophagy, was quantified in fluorescently labeled organelles in primary cell cultures, using two high throughput imaging methods Imagestream (Amnis) and IN Cell Analyzer 1000 (GE Healthcare Life Sciences). We studied colocalization between mitochondria and autophagosomes in fixed sections using confocal microscopy. Results: We validated our imaging methods for RedMIT/GFP-LC3 mouse cells, showing that colocalization of red fluorescent mitochondria and green fluorescent autophagosomes is a useful indicator of mitophagy. We showed that colocalization increases when lysosomal processing is impaired. Further, colocalization of mitochondrial fragments and autophagosomes is increased in cultures from the OPA1Q285STOP/RedMIT/GFP-LC3 mice compared to RedMIT/GFP-LC3 control mouse cells that were wild type for OPA1. This was apparent in both mouse embryonic fibroblasts (MEFs) using IN Cell 1000 and in splenocytes using ImageStream imaging flow cytometer (Amnis). We confirmed that this represents increased mitophagic flux using lysosomal inhibitors. We also used microscopy to investigate the level of mitophagy in the retina from the OPA1Q285STOP/RedMIT/GFP LC3 mice and the RedMIT/GFP-LC3 control mice. However, the expression levels of fluorescent proteins and the image signal-to-background ratios precluded the detection of colocalization so we were unable to show any difference in colocalization between these mice. Conclusions: We show that colocalization of fluorescent mitochondria and autophagosomes in cell cultures, but not fixed tissues from the RedMIT/GFP-LC3, can be used to detect mitophagy. We used this model to confirm that mitophagy is increased in a mouse model of ADOA. It will be useful for cell based studies of diseases caused by impaired mitochondrial dynamics. PMID- 30283780 TI - The Actin Cytoskeleton: A Mechanical Intermediate for Signal Integration at the Immunological Synapse. AB - The immunological synapse (IS) is a specialized structure that serves as a platform for cell-cell communication between a T cell and an antigen-presenting cell (APC). Engagement of the T cell receptor (TCR) with cognate peptide-MHC complexes on the APC activates the T cell and instructs its differentiation. Proper T cell activation also requires engagement of additional receptor-ligand pairs, which promote sustained adhesion and deliver costimulatory signals. These events are orchestrated by T cell actin dynamics, which organize IS components and facilitate their signaling. The actin network flows from the edge of the cell inward, driving the centralization of TCR microclusters and providing the force to activate the integrin LFA-1. We recently showed that engagement of LFA-1 slows actin flow, and that this affects TCR signaling. This study highlights the physical nature of the IS, and contributes to a growing appreciation in the field that mechanosensing and mechanotransduction are essential for IS function. Additionally, it is becoming clear that there are multiple types of actin structures at the IS that promote signaling in distinct ways. How the different actin structures contribute to force production and mechanotransduction is just beginning to be explored. In this Perspective, we will feature recent work from our lab and others, that collectively points toward a model in which actin dynamics drive mechanical signaling and receptor crosstalk during T cell activation.

AB - Over 100,000 patients in the United States are currently waiting for a kidney transplant. With just over 10,000 cadaveric kidneys transplanted annually, it is of the utmost importance to optimize kidney viability upon transplantation. One exciting avenue may be xenotransplantation, which has rejuvenated interest after advanced gene editing techniques have been successfully used in swine. Simultaneously, acute kidney injury (AKI) is associated with high morbidity and mortality and currently lacks effective treatment. Animal models have been used extensively to address both of these issues, with recent emphasis on renal progenitor cells (RPCs). Due to anatomical similarities to humans we aimed to examine progenitor cells from the renal papillae of swine kidneys. To do this, RPCs were dissected from the renal papillae of healthy swine. Cell surface marker expression, proliferation, and differentiation of the RPCs were tested in vitro. Additionally, a mixed lymphocyte reaction was performed to examine immunomodulatory properties. RPCs displayed spindle shaped morphology with limited self-renewing capacity. Isolated RPCs were positive for CD24 and CD133 at early passages, but lost expression with subsequent passaging. Similarly, RPCs displayed myogenic, osteogenic, and adipogenic differentiation capacities at passage 2, but largely lost this by passage 6. Lastly, direct contact of RPCs with human lymphocytes increased release of IL6 and IL8. Taken together, RPCs from the papilla of porcine kidneys display transient stem cell properties that are lost with passaging, and either represent multiple types of progenitor cells, or a multipotent progenitor population. In instances of ischemic insult, augmentation of/with RPCs may potentiate regenerative properties of the kidney. While the use of swine for transplantation and ischemia studies confers obvious advantages, the populations of different progenitor cell populations within pig kidneys warrants further investigation. Ultimately, while gene editing techniques enhance the potential for xenotransplantation of organs or cells, the ultimate success of this strategy may be determined by the (dis)similarities of RPCs from different species.

AB - Retinal degenerations are a heterogeneous group of diseases characterized by death of photoreceptors and progressive loss of vision. Retinal degenerations are a major cause of blindness in developed countries (Bourne et al., 2017; De Bode, 2017) and currently have no cure. In this review, we will briefly review the latest advances in therapies for retinal degenerations, highlighting the current barriers to study and develop therapies that promote photoreceptor regeneration in mammals. In light of these barriers, we present zebrafish as a powerful model to study photoreceptor regeneration and their integration into retinal circuits after regeneration. We outline why zebrafish is well suited for these analyses and summarize the powerful tools available in zebrafish that could be used to further uncover the mechanisms underlying photoreceptor regeneration and rewiring. In particular, we highlight that it is critical to understand how rewiring occurs after regeneration and how it differs from development. Insights derived from photoreceptor regeneration and rewiring in zebrafish may provide leverage to develop therapeutic targets to treat retinal degenerations. PMID- 30283782 TI - Neprilysin Inhibitors and Bradykinin. AB - Bradykinin has important physiological actions related to the regulation of blood vessel tone and renal function, and protection from ischemia reperfusion injury. However, bradykinin also contributes to pathological states such as angioedema and inflammation. Bradykinin is metabolized by many different peptidases that play a major role in the control of bradykinin levels. Peptidase inhibitor therapies such as angiotensin converting enzyme (ACE) and neprilysin inhibitors increase bradykinin levels, and the challenge for such therapies is to achieve the beneficial cardiovascular and renal effects without the adverse consequences such as angioedema that may result from increased bradykinin levels. Neprilysin also metabolizes natriuretic peptides. However, despite the potential therapeutic benefit of increased natriuretic peptide and bradykinin levels, neprilysin inhibitor therapy has only modest efficacy in essential hypertension and heart failure. Initial attempts to combine neprilysin inhibition with inhibition of the renin angiotensin system led to the development of omapatrilat, a drug that combines ACE and neprilysin inhibition. However, omapatrilat produced an unacceptably high incidence of angioedema in patients with hypertension (2.17%) in comparison with the ACE inhibitor enalapril (0.68%), although angioedema incidence was less in patients with heart failure with reduced ejection fraction (HFrEF) treated with omapatrilat (0.8%), and not different from that for enalapril therapy (0.5%). More recently, LCZ696, a drug that combines angiotensin receptor blockade and neprilysin inhibition, was approved for the treatment of HFrEF. The approval of LCZ696 therapy for HFrEF represents the first approval of long-term neprilysin inhibitor administration. While angioedema incidence was acceptably low in HFrEF patients receiving LCZ696 therapy (0.45%), it remains to be seen whether LCZ696 therapy for other conditions such as hypertension is also accompanied by an acceptable incidence of angioedema.

AB - A comprehensive longitudinal understanding of the changing epidemiology of the agents causing bacteraemia and their AMR profiles in key locations is crucial for assessing the progression and magnitude of the global AMR crisis. We performed a retrospective analysis of routine microbiological data from April 1992 to December 2014, studying the time trends of non-Salmonella associated bacteraemia at a single Kathmandu healthcare facility. The distribution of aetiological agents, their antimicrobial susceptibility profiles, and the hospital ward of isolation were assessed. Two hundred twenty-four thousand seven hundred forty-one blood cultures were performed over the study period, of which, 30,353 (13.5%) exhibited growth for non-contaminant bacteria. We observed a significant increasing trend in the proportion of MDR non-Salmonella Enterobacteriaceae (p < 0.001), other Gram-negative organisms (p = 0.006), and Gram-positive organisms (p = 0.006) over time. Additionally, there was an annual increasing trend in the proportion of MDR organisms in bacteria-positive blood cultures originating from patients attending the emergency ward (p = 0.006) and the outpatient department (p = 0.006). This unique dataset demonstrates that community acquired non Salmonella bacteraemia has become an increasingly important cause of hospital admission in Kathmandu. An increasing burden of bacteraemia associated with MDR organisms in the community underscores the need for preventing the circulation of MDR bacteria within the local population. PMID- 30283785 TI - Airway Management During Anesthetic Induction of Secondary Laryngectomy for Recurrent Laryngeal Cancer: Three Cases of Report and Analysis. AB - Surgery for laryngeal cancer and the following recurrent tumor growth may further change the anatomy of the airway. Airway management during anesthesia induction is challenging for the patients undergoing secondary surgery due to recurrence of laryngeal cancer or its postoperative complication, but it has never been reported. In this report, we described three cases of anesthetic induction which had different process of airway events. The first case was given intravenous general anesthetic for induction and experienced failed intubation, difficult mask ventilation and emergent tracheostomy, eventually were rescued successfully. The second case presented a fixed metastatic mass about 6 cm diameter upon the primary surgical scar of incision and preoperative apnea, underwent fibroscopy guided conscious intubation and the process was uneventful. The third case had erythema and swelling under the mandible with erupted ulcer as well as neck immobility due to recurrent tumor. The anesthesiologist attempted fibroscopy guided intubation via nasal passage with a tracheal tube in 2.8 mm diameter but it was failed. Subsequently, tracheostomy was performed under bilateral superficial cervical plexus block and the dissected larynx by operation verified distorted structure of glottis with S-shaped stenosis. This report concludes that, during the anesthetic induction for this special type of surgery, a detailed and comprehensive evaluation of the airway, and a routine fibroscopic examination are especially important. PMID- 30283786 TI - The Hop Polyphenols Xanthohumol and 8-Prenyl-Naringenin Antagonize the Estrogenic Effects of Fusarium Mycotoxins in Human Endometrial Cancer Cells. AB - The Fusarium toxin zearalenone (ZEN) and its reductive metabolite alpha zearalenol (alpha-ZEL) are well-documented endocrine disruptors that are frequently found to contaminate cereal products, including beer. But also hop is known to represent a source for endocrine active compounds, containing amongst others xanthohumol (XAN), which might be converted to the potent phytoestrogen 8 prenylnaringenin (8-PN). In the present study, we investigated the interaction of these xenoestrogens in mixtures which might occur in beer. Estrogenicity was measured as induction of alkaline phosphatase (AlP) expression in estrogen sensitive Ishikawa cells. In binary combinations, XAN was found to act as a potent antagonist of mycotoxin-induced estrogenicity, significantly suppressing the AlP-inducing impact of both ZEN and alpha-ZEL at nanomolar concentrations. Also 8-PN antagonized the estrogenic stimulus of the two fungal metabolites, although less pronounced. These effects also manifested in combinations of three or four test compounds, and at the level of cell proliferation, that was assessed via an E-screen-like approach in Ishikawa cells. Of note, co-exposure to the investigated myco- and phyto-estrogens did not result in additive or overadditive/synergistic estrogenic effects in the applied test system. Being aware that the actual study is still limited to the in vitro situation, our results even suggest that prenylated chalkones from hops might protect against Fusarium toxin-induced endocrine disruptive activities at concentrations that can be reached by moderate beer consumption. PMID- 30283787 TI - Neoadjuvant Chemotherapy in Patients With Muscle-Invasive Bladder Cancer and Its Impact on Surgical Morbidity and Oncological Outcomes: A Real-World Experience. AB - Objectives: The purpose of this study was to investigate the impact of neoadjuvant chemotherapy (NAC) on perioperative morbidity and on oncological outcomes according to the type of chemotherapy regimen administered to patients with muscle-invasive bladder cancer (MIBC) who subsequently underwent radical cystectomy (RC). Methods: Data were collected retrospectively on 40 patients with bladder urothelial carcinoma who had at least two cycles of NAC, followed by RC, from 2011 to 2015 at our institution. The outcomes evaluated were NAC toxicity, perioperative complications, cancer-specific, and overall survival. Results: Among these cases, 23 patients (57.5%) received methotrexate, vinblastine, doxorubicin and cisplatin (MVAC), 4 patients (10%) received gemcitabine and cisplatin (GC), and 13 patients (32.5%) received other regimes. The early and late postoperative complication rates were 35% and 12.5%. Regarding toxicity, 85% of patients had at least one side effect of NAC, but only 21.7% discontinued therapy in the MVAC group. The pathological complete response (pCR) rates for cisplatin-based regimens (MVAC and GC) and other regimens were 44.4 and 15.4%, respectively, (p = 0.09). The pathological partial response (pPR) rates for cisplatin-based regimens and other regimens were 66.7 and 15.4%, respectively, (p = 0.002). Patients treated with a cisplatin-based chemotherapy regimen had longer overall survival than those treated with other regimen (median 38.1 vs. 18.4 months, p = 0.01). Conclusions: NAC administration was not associated with high toxicity or surgical morbidity. The pathological response rates and survival outcomes in the cisplatin-based regimens were higher than with those with non cisplatin-based regimens. These data support the use, in patients elective to a neoadjuvant setting prior to RC for MBIC, of a cisplatin-based regimen.

AB - Tricuspid regurgitation (TR) may affect as much as 65-85% of the population with the prevalence of moderate-to-severe TR in the United States reported at greater than 1.6 million. However, only 8,000 tricuspid valve operations are performed annually in the United States. As severe TR is associated with poor outcomes, there is an unmet clinical need for surgical or percutaneous transcatheter based treatment of TR. Over the last two decades there have been significant developments in percutaneous transcatheter based therapies for valvular disease. However, this progress has not been mirrored for the tricuspid valve until recently; we are now at a cross-roads of new transcatheter devices becoming available for treatment of TR. In this review, we discuss the principles of performing transcatheter tricuspid valve replacement, analyze the devices that can be utilized and outline the challenges related to this procedure. PMID- 30283792 TI - Development of the Tonsil Microbiome in Pigs and Effects of Stress on the Microbiome. AB - Tonsils, lympho-epithelial tissues located at the junction of the oropharynx and nasopharynx, play a key role in surveillance, colonization, and persistence of inhaled and ingested pathogens. In pigs, the tonsils are a reservoir for numerous bacteria and viruses, including host-specific pathogens and potential zoonotic pathogens as well as commensal organisms. However, there are no in depth studies of the development of the tonsillar microbiome in pigs, or any mammal, over time. The goal of this study was to follow the development of the tonsil microbiome in healthy pigs from birth to market weight. Samples were collected using tonsil brushes from 16 piglets (4 each from 4 sows) at newborn, 1, 2, 3, and 4 weeks of age, and from 8 of those piglets at 6, 8, 10, 12, 16, and 19 weeks of age. Bacterial DNA was isolated from each sample and 16S rDNA genes were amplified and sequenced. Sequence analysis showed that members of the Streptococcaceae, Pasteurellaceae, and Moraxellaceae were present at all time points and represent the three most abundant families identified. Other community members appeared transiently or increased or decreased significantly with disruption events or stress. We observed four significant shifts in the tonsil community that coincided with well-defined disruption events: weaning plus addition of Carbadox plus movement to the nursery at week 3, removal of Carbadox and addition of Tylan at week 5, removal of Tylan and habitat change at week 9, and habitat change at week 16. Weaning triggered a bloom of Streptococcaeae and decrease of Moraxellaceae. The shift from Carbadox to Tylan led to reduction in Proteobacteria and Streptococcaceae but an increase in other Firmicutes, accompanied by a dramatic increase in community richness. Cessation of Tylan coincided with a return to a less rich community, and a bloom in Clostridiales. The final shift in habitat was accompanied by a decrease in Clostridiales and increase in Proteobacteria. The tonsillar microbiome of older pigs resembled the previously described mature core tonsillar microbiome. This study demonstrates a temporal succession in the development of the pig tonsillar microbiome, and significant community shifts that correlate with disruption events. PMID- 30283794 TI - Algorithm for the multidisciplinary management of hemorrhage in EUS-guided drainage for pancreatic fluid collections. AB - Pancreatic fluid collections (PFCs), common sequelae of acute or chronic pancreatitis, are broadly classified as pancreatic pseudocysts or walled-off necrosis according to the revised Atlanta classification. Endoscopic ultrasound (EUS)-guided drainage is often considered a standard first-line therapy preferable to surgical or interventional radiology approaches for patients with symptomatic PFC. EUS-guided drainage is effective and successful; it has a technical success rate of 90%-100% and a clinical success rate of 85%-98%. Recent studies have shown a 5%-30% adverse events (AEs) rate for the procedure. The most common AEs include infection, hemorrhage, perforation and stent migration. Hemorrhage, a severe and sometimes deadly outcome, requires a well-organized and appropriate treatment strategy. However, few studies have reported the integrated management of hemorrhage during EUS-guided drainage of PFC. Establishing a practical therapeutic strategy is an essential and significant step in standardized management. The aim of this review is to describe the current situation of EUS-guided drainage of PFCs, including the etiology and treatment of procedure-related bleeding as well as current problems and future perspectives. We propose a novel and meaningful algorithm for systematically managing hemorrhage events. To our limited knowledge, a multidisciplinary algorithm for managing EUS-guided drainage for PFC-related bleeding has not been previously reported. PMID- 30283793 TI - A Predominant Clonal Thromboembolic Meningoencephalitis Group of Histophilus somni Assigned by Major Outer Membrane Protein Gene Sequencing and Pulsed-Field Gel Electrophoresis. AB - Histophilus somni, a member of the family Pasteurellaceae, causes a variety of diseases, including thromboembolic meningoencephalitis (TEME) and respiratory diseases, which result in considerable economic losses to the cattle and sheep industries. In this study, 132 chronologically diverse isolates from cattle in Japan and 68 isolates from other countries comprising 49 from cattle and 19 from sheep were characterized using major outer membrane protein (MOMP) gene sequence and pulsed-field gel electrophoresis (PFGE) analyses. The H. somni isolates formed nine MOMP genetic clades (clade Ia, Ib, and II-VIII) and 10 PFGE clusters (HS1-HS10). Except for two (1.0%), all isolates fell into one of the nine MOMP genetic clades, while 62 (31.0%) isolates belonged to no PFGE cluster. MOMP genetic clade Ia and PFGE cluster HS1 were the major groups, and all HS1 isolates possessed the clade Ia MOMP gene. Isolates from TEME cases were significantly associated with these major groups (chi-square test, p < 0.0001), as 88.2% of the TEME isolates belonged to MOMP genetic clade Ia and PFGE cluster HS1, which formed the most predominant clonal group. After an inactivated vaccine using an HS1 strain with the clade Ia MOMP gene was introduced in Japan in late 1989, the number of TEME cases and isolates assigned into the clonal group decreased simultaneously. However, the proportions of clade Ia and cluster HS1 isolates from TEME cases remained high after 1990. These results suggest a close association of TEME with PFGE cluster HS1 and MOMP genetic clade Ia, and imply the presence of factors or characteristics commonly possessed by those strains that contribute to the development of TEME. PMID- 30283789 TI - Genetic and Tissue Engineering Approaches to Modeling the Mechanics of Human Heart Failure for Drug Discovery. AB - Heart failure is the leading cause of death in the western world and as such, there is a great need for new therapies. Heart failure has a variable presentation in patients and a complex etiology; however, it is fundamentally a condition that affects the mechanics of cardiac contraction, preventing the heart from generating sufficient cardiac output under normal operating pressures. One of the major issues hindering the development of new therapies has been difficulties in developing appropriate in vitro model systems of human heart failure that recapitulate the essential changes in cardiac mechanics seen in the disease. Recent advances in stem cell technologies, genetic engineering, and tissue engineering have the potential to revolutionize our ability to model and study heart failure in vitro. Here, we review how these technologies are being applied to develop personalized models of heart failure and discover novel therapeutics. PMID- 30283788 TI - Changing Metabolism in Differentiating Cardiac Progenitor Cells-Can Stem Cells Become Metabolically Flexible Cardiomyocytes? AB - The heart is a metabolic omnivore and the adult heart selects the substrate best suited for each circumstance, with fatty acid oxidation preferred in order to fulfill the high energy demand of the contracting myocardium. The fetal heart exists in an hypoxic environment and obtains the bulk of its energy via glycolysis. After birth, the "fetal switch" to oxidative metabolism of glucose and fatty acids has been linked to the loss of the regenerative phenotype. Various stem cell types have been used in differentiation studies, but most are cultured in high glucose media. This does not change in the majority of cardiac differentiation protocols. Despite the fact that metabolic state affects marker expression and cellular function and activity, the substrate composition is currently being overlooked. In this review we discuss changes in cardiac metabolism during development, the various protocols used to differentiate progenitor cells to cardiomyocytes, what is known about stem cell metabolism and how consideration of metabolism can contribute toward maturation of stem cell derived cardiomyocytes. PMID- 30283796 TI - Research progress on signaling pathways in cirrhotic portal hypertension. AB - Portal hypertension (PHT) is an important consequence of liver cirrhosis, which can lead to complications that adversely affect a patient's quality of life and survival, such as upper gastrointestinal bleeding, ascites, and portosystemic encephalopathy. In recent years, advances in molecular biology have led to major discoveries in the pathological processes of PHT, including the signaling pathways that may be involved: PI3K-AKT-mTOR, RhoA/Rho-kinase, JAK2/STAT3, and farnesoid X receptor. However, the pathogenesis of PHT is complex and there are numerous pathways involved. Therefore, the targeting of signaling pathways for medical management is lagging. This article summarizes the progress that has been made in understanding the signaling pathways in PHT, and provides ideas for treatment of the disorder. PMID- 30283795 TI - Mystery behind labial and oral melanotic macules: Clinical, dermoscopic and pathological aspects of Laugier-Hunziker syndrome. AB - Labial and oral melanotic macules are commonly encountered in a broad range of conditions ranging from physiologic pigmentation to a sign of an underlying life threatening disease. Although Laugier-Hunziker syndrome (LHS) shares some features of labial and oral pigmentation with a variety of conditions, it is a benign and acquired condition, frequently associated with longitudinal melanonychia. Herein, the demographic, clinical, dermoscopic, and pathological aspects of LHS were reviewed comprehensively. The important differential diagnoses of mucocutaneous and nail pigmentation are provided. An accurate diagnosis is crucial to design a reasonable medical strategy, including management options, malignant transformation surveillance, and psychological support. It is important that clinicians conduct long-term follow-up and surveillance due to the potential risks of malignant transformation and local severe complications in some conditions. PMID- 30283798 TI - PNPLA3 rs139051 is associated with phospholipid metabolite profile and hepatic inflammation in nonalcoholic fatty liver disease. AB - AIM: To investigate the effect of PNPLA3 polymorphisms on serum lipidomics and pathological characteristics in nonalcoholic fatty liver disease (NAFLD). METHODS: Thirty-four biopsy-proven NAFLD patients from Northern, Central, and Southern China were subjected to stratification by genotyping their single nucleotide polymorphisms (SNPs) in PNPLA3. Ultra performance liquid chromatographytandem mass spectrometry was then employed to characterize the effects of PNPLA3 SNPs on serum lipidomics. In succession, correlation analysis revealed the association of PNPLA3-related lipid profile and hepatic pathological characteristics on a basis of steatosis, activity, and fibrosis assessment. The variant-based scoring of hepatocyte steatosis, ballooning, lobular inflammation, and liver fibrosis was finally performed so as to uncover the actions of lipidomics-affecting PNPLA3 SNPs in NAFLD-specific pathological alterations. RESULTS: PNPLA3 SNPs (rs139051, rs738408, rs738409, rs 2072906, rs2294918, rs2294919, and rs4823173) demonstrated extensive association with the serum lipidomics, especially phospholipid metabolites [lysophosphatidylcholine (LPC), lysophosphatidylcholine plasmalogen (LPCO), lysophosphatdylethanolamine (LPE), phosphatidylcholine (PC), choline plasmalogen (PCO), phosphatidylethanolamine (PE), ethanolamine plasmalogen (PEO)], of NAFLD patients. PNPLA3 rs139051 (A/A genotype) and rs2294918 (G/G genotype) dominated the up-regulatory effect on phospholipids of LPCs (LPC 17:0, LPC 18:0, LPC 20:0, LPC 20:1, LPC 20:2) and LPCOs (LPC O-16:1, LPC O-18:1). Moreover, subjects with high-level LPCs/LPCOs were predisposed to low-grade lobular inflammation of NAFLD (rho: -0.407 to 0.585, P < 0.05-0.001). The significant correlation of PNPLA3 rs139051 and inflammation grading [A/A vs A/G + G/G: 0.50 (0.00, 1.75) vs 1.50 (1.00, 2.00), P < 0.05] further demonstrated its pathological role based on the modulation of phospholipid metabolite profile. CONCLUSION: The A/A genotype at PNPLA3 rs139051 exerts an up-regulatory effect on serum phospholipids of LPCs and LPCOs, which are associated with low-grade lobular inflammation of NAFLD. PMID- 30283797 TI - Gastrointestinal toxicity induced by microcystins. AB - Microcystins (MCs) are produced by certain bloom-forming cyanobacteria that can induce toxicity in various organs, including renal toxicity, reproductive toxicity, cardiotoxicity, and immunosuppressive effects. It has been a significant global environmental issue due to its harm to the aquatic environment and human health. Numerous investigators have demonstrated that MC exposure can induce a widespread epidemic of enterogastritis with symptoms similar to food poisoning in areas close to lakes. Both in vivo and in vitro studies have provided evidence of positive associations between MC exposure and gastrointestinal toxicity. The toxicity of MCs on the gastrointestinal tract is multidimensional. MCs can affect gastrointestinal barrier function and shift the structure of gut microbiota in different gut regions. Furthermore, MCs can inhibit the secretion of gastrointestinal digestive enzymes and the release of inflammatory cytokines, which affects the expression of immune-related genes in the intestine. The damage of the intestine is closely correlated to MC exposure because the intestine is the main site for the digestion and absorption of nutrients. The damage to the gastrointestinal tract due to MCs was summarized from different aspects, which can be used as a foundation for further exploration of molecular damage mechanisms. PMID- 30283799 TI - Recurrent carpal tunnel syndrome: Evaluation and treatment of the possible causes. AB - AIM: To investigate the causes of the recurrent carpal tunnel syndrome (CTS) and implemented surgical interventions. METHODS: Four hundred and eighty-seven patients, who were diagnosed with CTS and underwent surgical intervention between October 2016 and September 2007, were evaluated in this retrospective study. The age, gender, physical evaluation findings, electrophysiological examination reports and implemented surgical treatment methods were analyzed. RESULTS: Thirty nine of the cases were operated due to recurrent CTS. Further examination of the patients with recurrent CTS revealed that ten cases had diabetic polyneuropathy, three cases had hypothyroidism, two cases had rheumatoid arthritis and one case had systemic amyloidosis. Postoperative electromyography confirmed the neuropathy was due to systemic diseases. The remaining 23 patients with recurrent CTS did not have any systemic disease and all of them had applied previously to another health center. CONCLUSION: We concluded that the recurrence rates in CTS might be decreased with exploration and incision of the entire transverse ligament. Damage to the motor and sensory branches of the median nerve could be avoided with an incision on the ulnar side. PMID- 30283800 TI - Adjuvant chemotherapy with S-1 plus oxaliplatin improves survival of patients with gastric cancer after D2 gastrectomy: A multicenter propensity score-matched study. AB - AIM: To investigate the safety and efficacy of S-1 plus oxaliplatin (SOX) as an adjuvant chemotherapy regimen in gastric cancer (GC) after D2 dissection. METHODS: GC Patients who underwent D2 gastrectomy from September 2009 to December 2011 in four Chinese institutions were enrolled. Patients with stage IB-IIIC GC, who received adjuvant SOX treatment were matched by propensity scores with those who underwent surgery alone and those who conducted capecitabine plus oxaliplatin (XELOX) regimen. Disease-free survival (DFS) and overall survival (OS) were compared among the groups. In addition, adverse events in SOX patients were analyzed. RESULTS: Of 1944 GC patients who underwent D2 dissection, 867 were included for analysis. One hundred and seventeen patients treated with SOX were matched to 234 patients who conducted surgery alone. Fifty-seven patients treated with SOX were matched to 57 patients who received XELOX. The estimated five-year DFS was 57.5% in the adjuvant SOX group which was higher than that (44.6%) in the surgery alone group (P = 0.001); and the estimated five-year OS was 68.3% which was higher than that (45.8%) of surgery alone group (P < 0.001). Survival benefit was also revealed in stage III and > 60 years old subgroups (P < 0.001 and P = 0.015, respectively). Compared with XELOX regimen, SOX showed no significant difference in DFS (P = 0.340) and OS (P = 0.361). The most common >= 3 grade adverse events of SOX regimen were neutropenia (22.6%), leukopenia (8.9%) and thrombocytopenia (5.6%). CONCLUSION: Compared with surgery alone, SOX regimen significantly improves the long-term survival and has acceptable toxicity in patients with stage IB-IIIC GC after D2 dissection. It may be a novel adjuvant chemotherapy regimen in GC patients. PMID- 30283802 TI - Unusual complication in patient with Gardner's syndrome: Coexistence of triple gastrointestinal perforation and lower gastrointestinal bleeding: A case report and review of literature. AB - Gardner's syndrome (GS) is a rare syndrome with autosomal dominant inheritance, which is characterized by multiple intestinal polyps, dental anomalies, desmoid tumors, and soft tissue tumors. All gastrointestinal symptoms seen in GS are associated with the underlying familial adenomatosis polyposis and abdominal desmoid tumors, with the most common symptoms being anemia, lower gastrointestinal bleeding, abdominal pain, diarrhea, obstruction, and mucous defecation. To our best knowledge, no case of GS that has presented with gastrointestinal perforation and bleeding has ever been reported in the English language medical literature. A 37-year-old male who had been diagnosed with GS five years earlier was referred to our clinic for lower gastrointestinal bleeding. Despite the absence of a bleeding focus on conventional angiography, the patient was operated on with laparotomy, due to the persistence of both signs and symptoms of mild peritonitis. On the laparotomy, the patient was noted to have areas of perforation in the duodenum, splenic flexura, and mid-rectum. The third and fourth part of the duodenum, the proximal 15 cm segment of the jejunum, a 10 cm segment of the terminal ileum, the whole colon, and the upper and middle rectum were resected, and duodeno-jejunal side-to-side anastomosis and terminal ileostomy were performed. The histopathological analysis of the large mass measuring 30 cm * 20 cm was reported as a desmoid tumor. The pathological examination of the tumor foci detected in the colonic specimen revealed poorly differentiated adenosquamous carcinoma. PMID- 30283801 TI - Rectal perforation by inadvertent ingestion of a blister pack: A case report and review of literature. AB - The accidental ingestion of a foreign body (FB) is a relatively common condition. In the present study, we report a peculiar case of rectal perforation, the first to our knowledge, caused by the inadvertent ingestion of a blister pill pack. The aim of this report is to illustrate the difficulties of the case from a diagnostic and therapeutic viewpoint as well as its unusual presentation. A 75 year-old woman, mentally impaired, arrived at our emergency department in critical condition. The computed tomography scan revealed a substantial abdominopelvic peritoneal effusion and free perigastric air. The patient was therefore submitted to an urgent exploratory laparotomy; a 2-cm long, full thickness lesion was identified in the anterior distal part of the intraperitoneal rectum. Hence, we performed a Hartmann's procedure. Because of her critical condition, the patient was eventually transferred to the Intensive Care Unit, where she died after 10 d, showing no surgical complication. The ingestion of FBs is usually treated with observation or endoscopic removal. Less than 1% of FBs are likely to cause an intestinal perforation. The intestinal perforation resulting from the unintentional ingestion of an FB is often a difficult challenge when it comes to treatment, due to its late diagnosis and the patients' deteriorated clinical condition. PMID- 30283803 TI - Laparoscopic repair via the transabdominal preperitoneal procedure for bilateral lumbar hernia: Three cases report and review of literature. AB - A lumbar hernia is a rare entity, and a bilateral lumbar hernia is much rarer. From May 2015 to October 2017, we treated only three patients with bilateral lumbar hernias. One patient came to the hospital presenting with right-sided abdominal pain, and the other two patients presented with bilateral lumbar masses. The previous bilateral lumbar hernia reported in the literature was repaired by open surgery. The laparoscopic approach via the transabdominal preperitoneal (TAPP) procedure with the self-gripping Parietex ProGripTM mesh was performed at our center. The laparoscopic repair was conducted by a skilled hernia surgeon, and was successfully performed in the three patients. The patients resumed a semi-liquid diet and had no activity restriction after six hours following the operation. No antibiotics were used after the surgery. The operative times of the three patients were 120 min, 85 min, and 130 min. The blood loss volumes of the three patients were 20 mL, 5 mL, and 5 mL. The visual analogue scale pain scores of the three patients were 1, 2, and 2 on postoperative day 1, and were 1, 2, and 1 on postoperative day 3. No perioperative complications, such as bulge, wound infection and hematoma, occurred after the surgery. All of the patients were discharged on the third day after the operation. There was no chronic pain and no hernia recurrence during the follow-up. This study showed that the laparoscopic TAPP approach with the self-gripping mesh is safe and feasible, and can be considered an alternative method for the treatment of bilateral lumbar hernias. PMID- 30283804 TI - Multiple Symmetric Lipomatosis (Madelung Disease) in a Large Canadian Family With the Mitochondrial MTTK c.8344A>G Variant. AB - Background. Multiple symmetric lipomatosis (MSL), also known as Madelung disease, is a rare adult-onset disorder characterized by benign lipomatosis usually localized to the nuchal and upper thoracic region. A subset of these patients has germline variants in mitochondrial DNA. Methods. Three siblings of Northern European descent with MSL were assessed initially and provided whole blood for DNA analysis. Family history revealed several additional affected siblings who were dispersed across Canada. Targeted histories were obtained from 6 additional affected family members by telephone interviews using a standardized questionnaire, and genomic DNA was obtained from saliva. Sequencing of mitochondrial DNA was performed. Genetic analysis. Eight affected individuals who were studied each had the MTTK gene c.8344A>G variant. None of the affected individuals had epilepsy, ataxia, or myopathy. Conclusion. In this extended Canadian family, the rare MTTK c.8344A>G variant was linked with Madelung disease in multiple family members. Knowing the likely basis of MSL in this family may help with diagnosis, genetic counseling, monitoring for associated phenotypes, and potential future targeted interventions. PMID- 30283805 TI - A Good Case of Recurrent Pneumonia. AB - Bordetella bronchiseptica infection is a common cause of pneumonia in animals but rarely causes disease in humans. Additionally, coinfection with Pneumocystis jirovecii is very uncommon and is occasionally seen in patients with acquired immunodeficiency syndrome (AIDS). We report a case of a 61-year-old HIV-negative man, who presented with hypoxic respiratory failure 2 days after completion of systemic intravenous antibiotic treatment for B bronchiseptica. His past medical history was significant for a benign thymoma. The patient was found to be coinfected with B bronchiseptica and P jirovecii. Laboratory results showed panhypogammaglobulinemia and low absolute B- and CD4 T-cells. Therefore, the patient was diagnosed with Good's syndrome. However, despite treatment with intravenous antibiotics and intravenous immunoglobulin, the patient continued to deteriorate and expired. This patient demonstrates the importance of recognizing this rare immunodeficiency early in order to improve morbidity and mortality. Furthermore, this case highlights the importance of early immunoglobulin screening in the presence of asymptomatic thymoma. PMID- 30283806 TI - Atrial Fibrillation in a Patient With an Accessory Pathway. AB - A 24-year-old man with history of unspecified arrhythmia presented with palpitations and chest pain. Initial electrocardiogram (ECG) revealed irregular tachycardia with varying QRS width: 150 to 200 beats per minute for narrow complexes and 300 beats per minute for wide complexes. Following cardioversion, ECG revealed sinus tachycardia with a preexcitation pattern of positive delta waves in the anterolateral leads and negative delta waves in inferior leads. The patient remained in sinus rhythm and underwent successful ablation of a right posteroseptal accessory pathway. Subsequent ECG showed upright T waves in the leads I, aVL, and V2-6, large inverted T waves in leads III and aVF, and no delta waves. This case serves as an important reminder that atrial fibrillation (AF) in the presence of an accessory pathway may present with confounding ECG features, potentially leading to incorrect diagnoses and treatments that may be life threatening. Despite 10% to 30% prevalence of AF in the presence of an accessory pathway and the relative awareness of Wolff-Parkinson-White syndrome among general internal medicine providers, the clinical recognition of Wolff-Parkinson White syndrome may be hindered in the presence of preexcited AF. PMID- 30283808 TI - Chilaiditi Syndrome Complicated by Cecal Perforation in the Setting of Scleroderma. AB - Chilaiditi syndrome is a very rare disorder characterized by abdominal pain due to the entrapment of the colon between the liver and the diaphragm. However, it is rare to have bowel perforation as a complication of this syndrome with only 2 cases reported to date. In this article, we present the case of a 56-year-old woman with medical history of scleroderma who presents with abdominal pain and was found to have colonic perforation from Chilaiditi syndrome. She was also incidentally found to have cecal adenocarcinoma. Sometimes abdominal pain in patients with Chilaiditi syndrome may be more than benign and calls for increased attention from clinicians regarding this. PMID- 30283807 TI - Embolizing Massive Right Atrial Thrombus in a HIV-Infected Patient. AB - The risk of thromboembolism is increased when associated with the human immunodeficiency viral (HIV) infection. Various factors are involved in promoting thrombosis, and the presence of a patent foramen ovale augments the potential for a paradoxical embolism. We describe the case of a 56-year-old man receiving antiretroviral therapy with features of right heart failure and pulmonary embolism. Due to the high incidence of life-threatening thromboembolism in the HIV-infected group, the need for long-term anticoagulation has to be evaluated. PMID- 30283810 TI - In vitro Enzymatic Assays of Histone Decrotonylation on Recombinant Histones. AB - Class I histone deacetylases (HDACs) are efficient histone decrotonylases, broadening the enzymatic spectrum of these important (epi-)genome regulators and drug targets. Here, we describe an in vitro approach to assaying class I HDACs with different acyl-histone substrates, including crotonylated histones and expand this to examine the effect of inhibitors and estimate kinetic constants. PMID- 30283809 TI - The Relative Biological Effect of Spread-Out Bragg Peak Protons in Sensitive and Resistant Tumor Cells. AB - Purpose: Variations in the radiosensitivity of tumor cells within and between tumors impact tumor response to radiation, including the dose required to achieve permanent local tumor control. The increased expression of DNA-PKcs, a key component of a major DNA damage repair pathway in tumors treated by radiation, suggests that DNA-PKcs-dependent repair is likely a cause of tumor cell radioresistance. This study evaluates the relative biological effect of spread out Bragg-peak protons in DNA-PKcs-deficient cells and the same cells transfected with a functional DNA-PKcs gene. Materials and Methods: A cloned radiation sensitive DNA-PKcs-deficient tumor line and its DNA-PKcs-transfected resistant counterpart were used in this study. The presence of functional DNA-PKcs was evaluated by DNA-PKcs autophosphorylation. Cells to be proton irradiated or x irradiated were obtained from the same single cell suspension and dilution series to maximize precision. Cells were concurrently exposed to 6-MV x-rays or mid 137 MeV spread-out Bragg peak protons and cultured for colony formation. Results: The surviving fraction data were well fit by the linear-quadratic model for each of 8 survival curves. The results suggest that the relative biological effectiveness of mid spread-out Bragg peak protons is approximately 6% higher in DNA-PKcs mediated resistant tumor cells than in their DNA-PKcs-deficient and radiation sensitive counterpart. Conclusion: DNA-PKcs-dependent repair of radiation damage is less capable of repairing mid spread-out Bragg peak proton lesions than photon induced lesions, suggesting protons may be more efficient at sterilizing DNA-PKcs expressing cells that are enriched in tumors treated by conventional fractionated dose x-irradiation. PMID- 30283811 TI - Pentylenetetrazole (PTZ)-induced Convulsion Assay to Determine GABAergic Defects in Caenorhabditis elegans. AB - Pentylenetetrazole (PTZ) is a GABAA receptor antagonist and is used to monitor presynaptic defects in the release of the inhibitory neurotransmitter GABA. PTZ is a competitive inhibitor of GABA, and prevents binding of GABA on the GABAA receptors present on the surface of muscle. In the absence of GABA binding, the excitatory to inhibitory signal ratio increases resulting in a convulsive phenotype. This assay provides a fast and reliable method to detect presynaptic defects in GABAergic synaptic transmission. The assay is based on correlating the extent of convulsions with the degree of presynaptic GABA release defects. PMID- 30283812 TI - Mononuclear cell transcriptome changes associated with dimethyl fumarate in MS. AB - Objective: To identify short-term changes in gene expression in peripheral blood mononuclear cells (PBMCs) associated with treatment response to dimethyl fumarate (DMF, Tecfidera) in patients with relapsing-remitting MS (RRMS). Methods: Blood samples were collected from 24 patients with RRMS (median Expanded Disability Status Scale score, 2.0; range 1-7) at baseline, 6 weeks, and 15 months after the initiation of treatment with DMF (BG-12; Tecfidera). Seven healthy controls were also recruited, and blood samples were collected over the same time intervals. PBMCs were extracted from blood samples and sequenced using next-generation RNA sequencing. Treatment responders were defined using the composite outcome measure "no evidence of disease activity" (NEDA-4). Time-course and cross-sectional differential expression analyses were performed to identify transcriptomic markers of treatment response. Results: Treatment responders (NEDA-4 positive, 8/24) over the 15-month period had 478 differentially expressed genes (DEGs) 6 weeks after the start of treatment. These were enriched for nuclear factor (erythroid-derived 2)-like 2 (Nrf2) and inhibition of nuclear factor kappaB (NFkappaB) pathway transcripts. For patients who showed signs of disease activity, there were no DEGs at 6 weeks relative to their (untreated) baseline. Contrasting transcriptomes expressed at 6 weeks with those at 15 months of treatment, 0 and 1,264 DEGs were found in the responder and nonresponder groups, respectively. Transcripts in the nonresponder group (NEDA-4 negative, 18/24) were enriched for T-cell signaling genes. Conclusion: Short-term PBMC transcriptome changes reflecting activation of the Nrf2 and inhibition of NFkappaB pathways distinguish patients who subsequently show a medium-term treatment response with DMF. Relative stabilization of gene expression patterns may accompany treatment associated suppression of disease activity.

AB - Objective: To identify underlying genetic causes in patients with pediatric movement disorders by genetic investigations. Methods: All patients with a movement disorder seen in a single Pediatric Genetic Movement Disorder Clinic were included in this retrospective cohort study. We reviewed electronic patient charts for clinical, neuroimaging, biochemical, and molecular genetic features. DNA samples were used for targeted direct sequencing, targeted next-generation sequencing, or whole exome sequencing. Results: There were 51 patients in the Pediatric Genetic Movement Disorder Clinic. Twenty-five patients had dystonia, 27 patients had ataxia, 7 patients had chorea-athetosis, 8 patients had tremor, and 7 patients had hyperkinetic movements. A genetic diagnosis was confirmed in 26 patients, including in 20 patients with ataxia and 6 patients with dystonia. Targeted next-generation sequencing panels confirmed a genetic diagnosis in 9 patients, and whole exome sequencing identified a genetic diagnosis in 14 patients. Conclusions: We report a genetic diagnosis in 26 (51%) patients with pediatric movement disorders seen in a single Pediatric Genetic Movement Disorder Clinic. A genetic diagnosis provided either disease-specific treatment or effected management in 10 patients with a genetic diagnosis, highlighting the importance of early and specific diagnosis. PMID- 30283813 TI - Connectome of the Suprachiasmatic Nucleus: New Evidence of the Core-Shell Relationship. AB - A brain clock, constituted of ~20,000 peptidergically heterogeneous neurons, is located in the hypothalamic suprachiasmatic nucleus (SCN). While many peptidergic cell types have been identified, little is known about the connections among these neurons in mice. We first sought to identify contacts among major peptidergic cell types in the SCN using triple-label fluorescent immunocytochemistry (ICC). To this end, contacts among vasoactive intestinal polypeptide (VIP), gastrin-releasing peptide (GRP), and calretinin (CALR) cells of the core, and arginine vasopressin (AVP) and met-enkephalin (ENK) cells of the shell were analyzed. Some core-to-shell and shell-to-core communications are specialized. We found that in wild-type (WT) mice, AVP fibers make extremely sparse contacts onto VIP neurons but contacts in the reverse direction are numerous. In contrast, AVP fibers make more contacts onto GRP neurons than conversely. For the other cell types tested, largely reciprocal connections are made. These results point to peptidergic cell type-specific communications between core and shell SCN neurons. To further understand the impact of VIP-to AVP communication, we next explored the SCN in VIP-deficient mice (VIP-KO). In these animals, AVP expression is markedly reduced in the SCN, but it is not altered in the paraventricular nucleus (PVN) and supraoptic nucleus (SON). Surprisingly, in VIP-KO mice, the number of AVP appositions onto other peptidergic cell types is not different from controls. Colchicine administration, which blocks AVP transport, restored the numbers of AVP neurons in VIP-KO to that of WT littermates. The results indicate that VIP has an important role in modulating AVP expression levels in the SCN in this mouse.

PMID- 30283816 TI - Protein network analysis reveals selectively vulnerable regions and biological processes in FTD. AB - Objective: The neuroanatomical profile of behavioral variant frontotemporal dementia (bvFTD) suggests a common biological etiology of disease despite disparate pathologic causes; we investigated the genetic underpinnings of this selective regional vulnerability to identify new risk factors for bvFTD. Methods: We used recently developed analytical techniques designed to address the limitations of genome-wide association studies to generate a protein interaction network of 63 bvFTD risk genes. We characterized this network using gene expression data from healthy and diseased human brain tissue, evaluating regional network expression patterns across the lifespan as well as the cell types and biological processes most affected in bvFTD. Results: We found that bvFTD network genes show enriched expression across the human lifespan in vulnerable neuronal populations, are implicated in cell signaling, cell cycle, immune function, and development, and are differentially expressed in pathologically confirmed frontotemporal lobar degeneration cases. Five of the genes highlighted by our differential expression analyses, BAIAP2, ERBB3, POU2F2, SMARCA2, and CDC37, appear to be novel bvFTD risk loci. Conclusions: Our findings suggest that the cumulative burden of common genetic variation in an interacting protein network expressed in specific brain regions across the lifespan may influence susceptibility to bvFTD.

AB - Cannabidiol (CBD) is 1 of > 100 cannabinoids found in Cannabis sativa L. (Cannabis spp. or Cannabis). Despite its complex and rapidly evolving regulatory status in the United States, projected retail sales of CBD products-hemp, Cannabis and pharmaceutical-are as high as $1.9 billion by 2020. CBD products can currently be purchased online, over the counter, and at Cannabis-specific dispensaries throughout most parts of the country, despite the fact that CBD is presently deemed a Schedule I controlled substance by the U.S. Drug Enforcement Administration and renounced as a dietary supplement ingredient by the U.S. Food and Drug Administration (FDA). These products are largely unregulated, and are being used predominantly to treat specific medical conditions. Recent FDA approval of Epidiolex (CBD) as a treatment for certain pediatric seizure disorders will prompt scheduling of CBD and likely alter FDA enforcement of the Federal Food, Drug, and Cosmetic Act (FD&C), which to date has mostly been in the form of warning letters. Persuasive legal arguments contend that CBD's legal status is based on its source. According to these arguments, there are three legal sources. CBD-derived from: (1) parts of the Cannabis plant that do not meet the definition of cannabis in the Controlled Substances Act (CSA); (2) imported "non-psychoactive hemp"; and (3) "Industrial hemp" cultivated as part of a state pilot program per the 2014 Farm Act. Although CBD's lawful status with respect to the CSA appears to be expanding, its future regulatory status with respect to the FD&C Act is difficult to predict. PMID- 30283823 TI - Fecal Host Transcriptomics for Non-Invasive Human Mucosal Immune Profiling: Proof of Concept in Clostridium Difficile Infection. AB - Background: Host factors play an important role in pathogenesis and disease outcome in Clostridium difficile infection (CDI), and characterization of these responses could uncover potential host biomarkers to complement existing microbe based diagnostics. Methods: We extracted RNA from fecal samples of patients with CDI and profiled human mRNA using amplicon-based next-generation sequencing (NGS). We compared the fecal host mRNA transcript expression profiles of patients with CDI to controls with non-CDI diarrhea. Results: We found that the ratio of human actin gamma 1 (ACTG1) to 16S ribosomal RNA (rRNA) was highly correlated with NGS quality as measured by percentage of reads on target. Patients with CDI could be differentiated from those with non-CDI diarrhea based on their fecal mRNA expression profiles using principal component analysis. Among the most differentially expressed genes were ones related to immune response (IL23A, IL34) and actin-cytoskeleton function (TNNT1, MYL4, SMTN, MYBPC3, all adjusted P-values < 1 * 10-3). Conclusions: In this proof-of-concept study, we used host fecal transcriptomics for non-invasive profiling of the mucosal immune response in CDI. We identified differentially expressed genes with biological plausibility based on animal and cell culture models. This demonstrates the potential of fecal transcriptomics to uncover host-based biomarkers for enteric infections. PMID- 30283824 TI - Cystic Fibrosis Mice Develop Spontaneous Chronic Bordetella Airway Infections. AB - Chronic pulmonary disease and infection is the primary cause of morbidity and mortality in people with cystic fibrosis (CF). Though Pseudomonas aeruginosa, is most commonly found in the airways of individuals with CF, there is increasing appreciation for the diversity of the CF microbiome, including other taxa such as Bordetella. Here we describe the identification and impact of Bordetella pseudohinzii infection in CF mice, which previously have not been thought to develop spontaneous airway infections. We determined that CF mice are more susceptible to the B. pseudohinzii infections, and less able to resolve the infection than non-CF mice. Moreover, in both CF and non-CF mice, B. pseudohinzii infections lead to markedly reduced respiratory rates and a CF-specific immune response. These results establish the CF mouse model as an important tool for the study of CF-relevant infection and highlight the potential contribution of Bordetella to CF clinical pathology. PMID- 30283825 TI - A Case of Familial Male-Limited Precocious Puberty in a Child With Klinefelter Syndrome. AB - Familial male-limited precocious puberty (FMPP) is an autosomal dominant, male limited disorder that causes peripheral precocious puberty in boys. Klinefelter syndrome (47, XXY) is the most common chromosomal aberration in males with associated infertility, hypogonadism, and learning disability. We report here a case of Klinefelter syndrome in a patient with FMPP. A 6-year-old boy was referred to our pediatric endocrinology department for accelerated linear growth and premature pubic hair development. He was diagnosed with FMPP based on clinical, laboratory, and genetic sequencing. Increased levels of gonadotropins prompted further investigation, leading to a subsequent diagnosis of Klinefelter syndrome through karyotype analysis. This case illustrates that patients with FMPP and elevated gonadotropins should encourage further investigation by physicians. We recommend the use of karyotype analysis in such patients who are not receiving aromatase inhibitor therapy. We hypothesize that his mutation or pretreatment with aromatase inhibitors may have a protective effect on testosterone production and sperm viability. PMID- 30283826 TI - Prevalence of Somatic KCNJ5 Mutations in Thai Patients With Aldosterone-Producing Adrenal Adenomas. AB - Somatic KCNJ5 mutations result in excess aldosterone production and are reported to be more common in Asia than elsewhere. To assess the prevalence of somatic KCNJ5 mutations in Thai patients with aldosterone-producing adrenal adenomas (APAs) in a single tertiary center, we analyzed the paraffin-embedded tissue of KCNJ5 mutations from 96 patients with sporadic APAs who underwent unilateral laparoscopic adrenalectomy at our center during 2007 to 2016. We also assessed the clinical characteristics, treatment outcomes, and biochemistry and histologic differences among patients with and without somatic KCNJ5 mutations. Of the 96 patients with APA, 67 (70%) had somatic mutations of the KCNJ5 gene: 39 patients with p.G151R, 26 patients with p.L168R, one patient with p.T158A, and one patient with p.W126R. All patients presented with hypertension. Hypokalemia was documented in 98% of patients. The hypertension cure rate at 1 year after surgery was 35%. Patients with somatic KCNJ5 mutations required more potassium supplementation and had adrenal histology compatible with zona fasciculata-like cells compared with patients without the mutations (all P < 0.05). There were no significant differences in preoperative plasma aldosterone concentration (PAC), plasma renin activity, aldosterone/renin ratio, potassium level, treatment of hypertension, tumor size, and hypertension cure rate among patients in the KCNJ5 mutant and nonmutant groups. In a multivariate analysis, a higher PAC was associated with the presence of somatic KCNJ5 mutations. In summary, the prevalence of somatic KCNJ5 mutations in patients with sporadic APAs in Thailand, an Asian country with residents of different ethnic backgrounds, is comparable to previous reports in Asia. PMID- 30283828 TI - A Space to Promote Intentional Thoughtful Action. PMID- 30283827 TI - Significant Association of Aldosterone and Liver Fat Among HIV-Infected Individuals With Metabolic Dysregulation. AB - Objective: Fatty liver disease is increased among individuals with HIV. We sought to explore how aldosterone, a key hormone linked to insulin resistance and inflammation, relates to liver fat in the large population of individuals with HIV and metabolic abnormalities. Methods: Forty-six individuals with HIV and increased waist circumference and dysglycemia were assessed for liver fat using proton magnetic resonance spectroscopy. Serum aldosterone level was obtained following strictly controlled posture conditions and a standardized sodium diet and was related to liver fat. Results: Among the entire group [median (interquartile range) liver fat: 5% (3%, 12%) and homeostatic model assessment of insulin resistance: 1.74 (1.21, 2.83)], serum aldosterone significantly correlated with liver fat (r = 0.31; P = 0.049). Liver fat level was significantly higher in those with aldosterone above vs below the median [8% (3%, 20%) vs 4% (2%, 10%); P = 0.02]. In the presence of metabolic syndrome, individuals with aldosterone levels above vs below the median had markedly elevated liver fat values [14% (9%, 23%) vs 5% (3%, 12%); P = 0.005] and increased presence of fatty liver disease (FLD; 92% vs 50%; P = 0.02). Controlling for metabolic syndrome, hepatitis C virus, and alcohol use, aldosterone was a significant and independent predictor of liver fat (beta estimate: 0.6038, P = 0.01; overall model r 2 = 0.41, P = 0.0005) and FLD (OR: 1.38, P = 0.02; overall model r 2 = 0.28, P = 0.002). Conclusion: These data highlight a robust association between aldosterone and liver fat among individuals with HIV and metabolic dysregulation. Increased aldosterone may be a risk factor for liver fat accumulation among the population with HIV. PMID- 30283829 TI - Text Messaging in the Patient-Centered Medical Home to Improve Glucose Control and Retinopathy Screening. AB - Purpose: To evaluate the effectiveness of a text messaging program (TMP) to improve glucose control, retinopathy screening (RS) rates, and self-care behaviors in patients with uncontrolled type 2 diabetes. Methods: A single-group design with a quasi-systematic random sample (n=20) received educational/exhortational text messages on their cellular phones for 3 months. Subjects, 12 of whom identified as a minority ethnicity, were mostly male, aged 27-73 years. Results: Glucose control and RS rates improved significantly. Subjects (>70%) reported changes in self-care behaviors. Conclusion: Leveraging ubiquitous technology, a TMP for patients with limited access to healthcare education, holds promise. PMID- 30283830 TI - Partnering on the PRAISE Program: Putting Health Equity into Practice. AB - Purpose: The purpose of Preventive Health Education Resulting in Action Inspiring Success for Everyone (PRAISE) was to develop a community-driven program to encourage and support churches in sustainable health promotion and assessment efforts to improve African Americans' health knowledge and behaviors in Asheville, North Carolina. Methods: The PRAISE program provided technical support toward gaining recognition and an award for health promotion activities to 10 churches in year 1 and 5 additional churches in year 2. The Results-Based Accountability(c) (RBA) framework involved documentation of church health promotion activities and surveys of a convenience sample of congregants at nine churches before (presurvey, n=270) and after (postsurvey, n=241) the intervention. Differences in frequency of conduct of and participation in church health promotion activities and in congregant health knowledge and behaviors were assessed in 2015 and 2016. Results: Fourteen of the churches engaged in at least one health promotion activity and more than half offered healthier foods at gatherings, offered exercise opportunities, and held at least three health education activities. Seventy-two percent of congregants reported participating in at least one church health activity at postsurvey compared with 58% at presurvey. The proportion of congregants who had personal health knowledge and the proportion that rated their health as good or better were higher at postsurvey. Conclusion: Building on years of trust and collaboration among churches, local community organizations, and an academic partner, PRAISE in its first 2 years suggests that a community-driven approach can support health promotion and healthy behaviors, advancing health equity efforts. PMID- 30283832 TI - From Principles to Practice: One Local Health Department's Journey Toward Health Equity. AB - Few dispute that social determinants such as economics, education, and the environment are the true drivers of health. In fact, the recent "Public Health 3.0" publication is a national call to action for public health to focus upstream. Where there is less clarity is how to redesign public health practice to address social determinants. As an example of how local health departments can heed this national call, Harris County Public Health describes its movement from health equity principles to practice, which included reframing an understanding of health inequities and applying a multitiered infrastructure of policy and procedures for "retrofitting" practice. PMID- 30283831 TI - Measuring Medical Students' Preparedness and Skills to Provide Cross-Cultural Care. AB - Purpose: Cross-cultural education is an integral and required part of undergraduate medical curricula. However, the teaching of cross-cultural care varies widely and methods of evaluation are lacking. We sought to better understand medical students' perspectives on their own cultural competency across the 4-year curriculum using a validated survey instrument. Methods:We conducted an annual Internet-based survey at Harvard Medical School with students in all 4 years of training, for four consecutive years. We used a tool previously validated with residents and slightly modified it for medical students, assessing their (1) preparedness, (2) skillfulness, and (3) perspectives on the educational curriculum and learning climate. Results: Of 2592 possible survey responses, we received 1561 (60% response rate). Fourth-year students had significantly higher scores than first-year students (p<0.001) for all but one preparedness item (caring for transgender patients) and all but one skillfulness item (identifying ability to read/write English). Less than 50% of students felt adequately prepared/skilled by their fourth year on 8 of 11 preparedness items and 5 of 10 skillfulness items. Lack of practical experience caring for diverse patients was the most frequently cited challenge. Conclusions: While students reported that preparedness and skillfulness to care for culturally diverse patients seem to increase with training, fourth-year students still felt inadequately prepared and skilled in many important aspects of cross-cultural care. Medical schools can use this tool with students to self-assess cultural competency and to help guide enhancements to their curricula focusing on cross-cultural care. PMID- 30283833 TI - Perspectives on Barriers to Eating Healthy Among Food Pantry Clients. AB - Objective: To explore perspectives on barriers of eating healthy among food pantry clients. Methods: Food pantry clients participated in focus groups/interviews. Qualitative data were coded and analyzed using content analyses and grounded theory approach. Themes were then identified. Quantitative data were analyzed for frequencies and descriptives. Results: Fifty-four clients from 10 pantries participated in interviews/focus groups and completed questionnaires. Two major themes emerged: concern over obesity and other chronic diseases, and barriers to healthy eating. Several subthemes for barriers to healthy eating were identified: financial uncertainty, cost of healthy foods, lack of time, rationing food within family, lack of transportation, lack of adequate kitchen equipment, lack of nutrition knowledge and skills, and social support network. Conclusions: Issues identified above and those identified by others working with low-income populations need to be systematically addressed and incorporated into programs and nutrition education interventions for this group. PMID- 30283834 TI - Patterns of Communication Technology Utilization for Health Information Among Hispanics in South Carolina: Implications for Health Equity. AB - Background: Language, culture, geographic, social, and economic factors are associated with health disparities. Among more recent Hispanic immigrants, limited English proficiency and immigration status are barriers to health information and healthcare access. Improved access to culturally and linguistically tailored health information through technology could potentially enhance healthcare access and health outcomes. However, little is known about health information-seeking through technology among Hispanics in recent settlement areas. Purpose: The aim of this exploratory study was to describe patterns of self-reported utilization of technology for health information seeking among the growing Hispanic population in South Carolina (SC) over a period of 5 years. Methods: Descriptive, community-based, cross-sectional survey of 361 Hispanic adults residing in SC, conducted in 2011 and 2015/2016. Results: Reflective of reported national trends, self-reported accessibility and utilization of cellphones increased (89-96.6%) among this sample. Although computer ownership decreased (58-53.9%), internet utilization for health information-seeking increased (45-57.8%); more than 80% of participants indicated that they considered the internet a "good source of health information." The majority of participants in both time periods conducted health information searches in Spanish, although the reported access to English-language information increased over time. Conclusions: These findings illustrate the increasing access and utilization of technology for health information among Hispanics in SC, underscoring the need for broader dissemination of culturally and linguistically appropriate health information through accessible technology, including Spanish language websites. Recommendations for future research include examining relationships between technology access, health service access and utilization, and health behaviors among Hispanics in diverse geographic and social contexts. PMID- 30283835 TI - Racial and Ethnic Differences in Satisfaction with Care Coordination Among VA and non-VA Medicare Beneficiaries. AB - Purpose: Patients who have multiple sources of care are at risk for fragmented and uncoordinated care, which can lead to poorer outcomes. Veteran Medicare beneficiaries who use the Veterans Health Administration (VHA) system (VA users), particularly racial/ethnic minorities, often have complex medical conditions that may require care from multiple sources, leaving them especially vulnerable to the effects of fragmented care. We examined racial/ethnic differences in the level of satisfaction with care coordination among Medicare beneficiaries, comparing those who do and do not use the VHA healthcare system. Methods: We conducted a retrospective, pooled, cross-sectional study of Medicare beneficiaries using the 2009-2011 Medicare Current Beneficiary Survey. The outcomes are self-reported satisfaction with care items related to three dimensions of care coordination: (1) integrated care, (2) care continuity, and (3) follow-up care. We present descriptive statistics and use generalized linear models to examine racial/ethnic differences across VA and non-VA users, after accounting for other demographic characteristics, health status, functional limitations, insurance coverage, and geographic variation. Results: VA users are more likely to be very satisfied with receiving both integrated and follow-up care compared with non-VA users. Despite the existence of significant racial/ethnic disparities in the likelihood of being very satisfied with receiving well-coordinated care in the larger Medicare population, racial/ethnic minority VA users are just as likely as White non Hispanics to be very satisfied with receiving well-coordinated care. Conclusions: Future research should continue to study care coordination among VA users and reasons for preferring the VA over other healthcare systems, especially among racial/ethnic minority groups.

However, residents and medical students may not receive adequate training to effectively identify and intervene with patients who may be victims of IPV. The purpose of this study is to examine the background and clinical knowledge of IPV among primary care residents and medical students in the United States of America. Methods: Third and fourth year medial students (n=65) and primary care residents (n=60) participated in an online survey in 2013. Results: While the majority of the participants reported IPV was an important and relevant issue for their practice, approximately half of them had never talked about IPV with patients. Residents reported higher levels of background and knowledge of IPV than medical students. Knowing a victim of IPV, confidence about talking to patients about IPV, and talking to patients about IPV would be helpful to increase levels of background and knowledge of IPV. Conclusions: This study found that background and clinical knowledge of IPV can potentially affect physicians' approach with IPV victims. This study also demonstrated the need for future research in the development of effective programs and trainings to help bridge the gap between knowledge and implementation in medical practice. PMID- 30283837 TI - What an Emerging Trump Administration Means for Lesbian, Gay, Bisexual, and Transgender Health. AB - The policies of the Trump administration are likely to have direct and indirect implications for lesbian, gay, bisexual, and transgender (LGBT) health. With the assistance of a Republican-controlled Congress, President Trump may repeal President Obama's health reform law, undermine same-sex marriage laws and other nondiscrimination protections, reduce funding for research on sexual and gender minority health, and institutionalize discrimination through new legislation, such as the First Amendment Defense Act. Public health researchers, healthcare providers, and professional organizations must continue to combat discrimination and advocate for LGBT health equity under an emerging Trump presidency. PMID- 30283838 TI - Poverty and Breastfeeding: Comparing Determinants of Early Breastfeeding Cessation Incidence in Socioeconomically Marginalized and Privileged Populations in the FiNaL Study. AB - Purpose: Infant feeding differences are strongly tied to socioeconomic status. The goal of this study is to compare determinants of early breastfeeding cessation incidence in socioeconomically marginalized (SEM) and socioeconomically privileged (SEP) populations, focusing on birthing parents who intended to breastfeed. Methods: This cohort study includes data from 451 birthing parents in the Canadian province of Newfoundland and Labrador who reported intention to breastfeed in the baseline prenatal survey. Multivariate logistic regression techniques were used to assess the determinants of breastfeeding cessation at 1 month in both SEM and SEP populations. Results: The analysis data included 73 SEM and 378 SEP birthing parents who reported intention to breastfeed at baseline. At 1 month, 24.7% (18/73) in the SEM group had ceased breastfeeding compared to 6.9% (26/378) in the SEP group. In the SEP population, score on the Iowa Infant Feeding Attitude Scale (IIFAS) (odds ratio [OR] 3.33, p=0.01) was the sole significant determinant. In the SEM population, three significant determinants were identified: unpartnered marital status (OR 5.10, p=0.05), <1 h of skin-to skin contact after birth (OR 11.92, p=0.02), and negative first impression of breastfeeding (OR 11.07, p=0.01). Conclusion: These results indicate that determinants of breastfeeding cessation differ between SEM and SEP populations intending to breastfeed. Interventions intended on improving the SEM population's postpartum breastfeeding experience using best practices, increasing support, and ensuring at least 1 h of skin-skin contact may increase breastfeeding rates. PMID- 30283839 TI - A Pilot Study on the Psychosocial Health and Living Quality of Left-Behind Children in a Remote City of China. AB - Purpose: With the rapid economic development, China has undergone a large-scale migration, with many children left behind due to parental migration for better income. Little is known about the psychosocial health and living quality of the Chinese left-behind children (LBC) in remote cities, so this study aims at investigating the emotional and behavioral problems as well as the living qualities of LBC in remote cities of China. Methods: In this pilot cross sectional study, 45 schoolchildren (10-12 years old) from Guiyang, a remote city in China, were enrolled in the sampling. The Strength and Difficulties Questionnaire (SDQ) and Quality of Life Scale for Children and Adolescents (QLSCA) were used to evaluate the psychosocial health and living quality. The differences between LBC and control children and correlation factors were analyzed in this study. Results: LBC had a statistically significantly higher score in SDQ than in the control group with p-values that were all <0.01. The prosocial score in LBC was significantly lower than that of the control children (p<0.01). The scores on QLSCA were significantly lower for the LBC than for their counterparts (p<0.01). The emotional and behavioral problems (SDQ scores) and the living quality (QLSCA scores) are highly correlated. Conclusion: This preliminary study identified the severity of the psychosocial problem and the lower living quality with LBC in the remote city of China. This problem may relate to the lower education level of their caregivers. The LBC in remote cities of China need more psychosocial and educational support from schools and communities. PMID- 30283841 TI - Hispanic Youth Visits to Food and Beverage Company Websites. AB - Purpose: To measure disparities in exposure to food/beverage websites by Hispanic youth. Methods: Observational study using market research panel data compared frequency and time spent visiting food/beverage websites and the Internet overall for Hispanic and non-Hispanic children (6-11 years) and youth (6-17 years). Results: Hispanic children and youth, particularly Spanish-speaking youth, were less likely to visit the Internet overall, but more likely to visit food/beverages websites, compared with their non-Hispanic peers. Conclusions: Food and beverage company websites disproportionately appeal to Hispanic youth. Public health advocates and companies should take action to reduce Hispanic youth exposure to unhealthy food marketing online. PMID- 30283840 TI - Process Evaluation of a Peer-Driven, HIV Stigma Reduction and HIV Testing Intervention in Latino and African American Churches. AB - Purpose: Faith-based organizations may be effective in addressing HIV-related disparities, but few interventions have been implemented across diverse churches. The Facilitating Awareness to Increase Testing for HIV (FAITH) intervention harnessed peer leadership to decrease HIV stigma and promote HIV testing in African American and Latino congregations. A pilot study found more consistent effects among Latino congregations. This process evaluation evaluates implementation of FAITH to better understand the pilot study's findings. Methods: Data sources included HIV education and peer leader workshop evaluation forms, participant views of the community's perspective of HIV, and peer leader follow up interviews. Data were triangulated with systematic observation notes and analyzed using process-related themes of recruitment, reach, context, implementation, dose-delivered, and fidelity. Results: At the Latino churches (compared to the African American church), facilitators spent more time addressing community-based misconceptions about HIV. The peer leader model was well received, especially among Latino participants, and most said that after the workshop they felt comfortable speaking with others about HIV-related topics. Latino peer leaders reported speaking with up to 20 people within their social networks (particularly with family members); African Americans reported up to 4. Implementation challenges at the African American church may have contributed to the limited intervention effects. Nevertheless, we found the peer motivator model feasible and acceptable across diverse faith settings. Conclusion: Peer-based models within faith settings are promising for addressing HIV. However, differences among groups in HIV knowledge, social network characteristics and norms, and church preferences may influence overall effectiveness. PMID- 30283842 TI - Gone, But Not Forgotten? Survey of Resident Attitudes Toward a Cultural Standardized Patient Examination for a General Surgery Residency Program. AB - Purpose: Various tools have been utilized for cultural competency training in residency programs, including cultural standardized patient examinations. However, it is unknown whether residents feel the training they received has a long-term impact on how they care for patients. The purpose of this study was to assess whether surgical residents who participated in a cultural standardized patient examination view the experience as beneficial. Methods: Surgical residents who completed a standardized patient examination from Fall 2009 to Spring 2015 were asked to complete a 13-question survey assessing the following: (1) did participants feel prepared when dealing with patients from different cultural backgrounds, (2) did they feel the standardized patient experience was beneficial or improved their ability to care for patients, and (3) did they perceive that cultural competence was important when dealing with patients. Results: Sixty current/former residents were asked to participate and 24 (40%) completed the survey. All agreed cross-cultural skills were important and almost all reported daily interaction with patients from different cultural backgrounds. Sixteen participants (67%) reported the cultural standardized patient examination aided their ability to care for culturally dissimilar patients, and 13 (54%) said the training helped improve their communication skills with patients. Thirteen (54%) reported they would participate in another cultural standardized patient examination. Conclusion: Development of effective cultural competency training remains challenging. This study provides some preliminary results that demonstrate the potential lasting impact of cultural competency training. Participants found the skills gained from cultural standardized patient examinations helpful. PMID- 30283843 TI - Patterns in Liver-Related Health Outcomes with Hepatitis C Virus Treatments and Health Equity Implications for Decision Makers: A Cohort Analysis of Medicaid Patients. AB - Introduction: Hepatitis C virus (HCV) infection is a blood-borne communicable disease that, in perhaps 20% of cases, results in a chronic disease. However, traditional peginterferon/ribavirin therapies pose many adverse side effects that are difficult to tolerate, and many patients do not complete the therapy. However, healthcare access to these newer, efficacious treatments are reduced, due to inadequate or lack of coverage of direct acting antiviral (DAA) medication. The objective of this study was to evaluate the impact of HCV treatment regimens on outcomes of care for HCV-infected Medicaid beneficiaries without cirrhosis/liver disease scarring. Methods: A cohort analysis was performed to evaluate the changes in cirrhosis, hepatocellular carcinoma (liver cancer), and liver transplantation with use of HCV treatments in Medicaid beneficiaries with HCV, and was followed over a period of 10 years. The cohort of Medicaid beneficiaries and relevant variables were generated from published literature. Results: Finally, considering the impact on health expenditures due to improved access to new treatments in Medicaid beneficiaries, DAAs resulted in the lowest decompensated cirrhosis and hepatocellular carcinoma-related healthcare cost per person over the 10-year time frame the cohort was followed. Conclusions: The risk of liver-related disease is higher in patients with cirrhosis, as reaching treatment success results in continued disease progression, not normal health status; thus, liver cancer healthcare costs are higher in patients with cirrhosis, compared to those without cirrhosis.

PMID- 30283844 TI - Using Geospatial Analysis to Determine Access Gaps Among Children with Special Healthcare Needs. AB - Purpose: To examine geospatial gaps in identification and evaluation of children with special healthcare needs (CSHCN) within public child development centers (CDCs). Methods: A descriptive geospatial design was used to visually depict service gaps, proximity, and clustering of area-level sociodemographic attributes of Virginia counties, and patient-level data within each CDC. Results: Geospatial analysis shows population density of uninsured children against CDC resources. Data visualization facilitates policy advocacy based on the identification of care and screening gaps for CSHCN. Conclusion: This project illustrates the collaborative potential between researchers and Health Department members to identify gaps in access to care. PMID- 30283846 TI - The Harold Amos Medical Faculty Development Program: Evaluation of a National Program to Promote Faculty Diversity and Health Equity. AB - Purpose: The Harold Amos Medical Faculty Development Program (AMFDP), a national program of the Robert Wood Johnson Foundation, seeks to support academic physicians from historically disadvantaged backgrounds and serves as a model program for promoting faculty diversity and health equity. Our objective was to determine differences in scientific productivity, promotions and retentions, and leadership attainment among faculty applicants to this national minority faculty development program. Methods: Final-round interview applicants from 2003 to 2008 were selected. Differences in publications, grants, promotions/retentions, and leadership positions through 2013 were compared between funded scholars and unfunded nonscholars. Semistructured interviews were conducted to identify factors that facilitated and hindered academic success. Results: A total of 124 applicants (76 scholars and 48 nonscholars) who participated in final-round interviews from 2003 to 2008 were eligible. Scholars and nonscholars had similar number of publications. Scholars had greater number of grants and grant dollars, but differences were not significant after accounting for AMFDP program awards. Scholars were more likely to hold leadership positions (28% vs. 10%, p=0.02), but equally likely to be promoted (67% vs. 58%, p=0.32) and retained (84% vs. 75%, p=0.21). In interviews, all participants endorsed mentoring, funding, and nonscientific education to academic success, but scholars reported greater availability of leadership opportunities consequent to AMFDP. Conclusion: There were few differences in academic productivity attributable to a national faculty diversity program. However, program participants were more likely to endorse and attain leadership positions. Academic institutions should consider facilitating leadership development of minority faculty as a means of advancing health equity research and training. PMID- 30283847 TI - Exploring the Impact Factor: Medical Students Mentoring High School Students and Cultivating Cultural Humility. AB - Purpose: Diversity at all levels of medical training remains relatively stagnant, despite efforts to address equity in medical schools. Early career-specific mentoring may address barriers to the pursuit of medical education for students underrepresented in medicine (URiM). By surveying a program that engages medical students as drivers of career-specific mentorship for URiM high school students, this study evaluates medical student mentors' experiences mentoring and seeks to develop a mentorship curriculum. Methods: The authors describe a medical student led pipeline program, which connects medical students with URiM high school students. Medical student mentors participated in focus groups and gave written responses evaluating reasons for involvement, sociocultural attitudes, and skills needed for mentoring. Thematic analysis was applied. Results: Themes that emerged in this analysis include motivation to mentor, skills used to approach the mentoring relationship, and benefits to the mentor. Mentors felt their experiences had a high impact factor, and they employed dynamic discovery. It provided personal reward and a deeper understanding of disparities. Conclusion: Bringing medical school mentors together for peer to peer idea sharing, creating communities of practice, will help these students develop effective mentorship skills. A curriculum based on appreciative inquiry of mentors' strengths will enrich idea sharing, fostering cultural humility and avoiding burnout. Medical students involved in this program believe they gained benefits, including improving their mentorship skills, expanding their cultural humility, increasing their comfort with caring for underserved populations, and improving their ability to recognize health disparities. PMID- 30283848 TI - Psychosocial Factors Associated with Healthy and Unhealthy Interpregnancy Intervals. AB - Purpose: To examine the influence of psychosocial factors, including anxiety, depression, social support, maternal substance abuse, and intimate partner violence (IPV) on interpregnancy intervals (IPIs). Methods: B'more for Healthy Babies-Upton/Druid Heights is part of a citywide initiative to improve the health of at-risk pregnant women and their children. Participants with at least one prior birth completed baseline, postpartum, and 3-month follow-up surveys with questions about pregnancy, medical, and psychosocial history. Associations between IPI and the independent variables were assessed using chi-square analysis and analysis of variance. Multivariable multinomial logistic regression models examined significant associations while controlling for other independent variables and potential confounders. Results: Participants with current IPV were more likely to have a short IPI (odds ratio [OR]=13.1; 95% confidence interval [CI]=1.07-158.9; p=0.04) than healthy IPI. Women with family social support were more likely to have a healthy IPI (OR=5.88, 95% CI=1.02-31.25, p=0.05) than those without family social support. Maternal anxiety and depression did not significantly influence IPI. Conclusion: IPV increased the likelihood of having an unhealthy IPI among this population and family social support increased the likelihood of having a healthy IPI. Additional efforts to address IPV and enhance family social support may lead to improved pregnancy outcomes. PMID- 30283849 TI - Local Income Inequality, Individual Socioeconomic Status, and Unmet Healthcare Needs in Ohio, USA. AB - Purpose: Income inequality has been implicated as a potential risk to population health due to lower provision of healthcare services in deeply unequal countries or communities. We tested whether county economic inequality was associated with individual self-report of unmet healthcare needs using a state health survey data set. Methods: Adults residents of Ohio responding to the 2015 Ohio Medicaid Assessment Survey were included in the analysis. Ohio's 88 counties were classified into quartiles according to the Gini coefficient of income inequality. The primary outcome was a composite of self-reported unmet dental care, vision care, mental healthcare, prescription medication, or other healthcare needs within the past year. Unmet healthcare needs were compared according to county inequality quartile using weighted logistic regression. Results: The analytic sample included 37,140 adults. The weighted proportion of adults with unmet healthcare needs was 28%. In multivariable logistic regression, residents of counties in the highest (odds ratio [OR]=1.13, 95% confidence interval [CI]: 1.01 1.26; p=0.030) and second-highest (OR=1.16, 95% CI: 1.04-1.30; p=0.010) quartiles of income inequality experienced more unmet healthcare needs than residents of the most equal counties. Conclusion: Higher county-level income inequality was associated with individual unmet healthcare needs in a large state survey. This finding represents novel evidence for an individual-level association that may explain aggregate-level associations between community economic inequality and population health outcomes. PMID- 30283850 TI - Is a Patient's Current Address of Record a Reasonable Measure of Neighborhood Deprivation Exposure? A Case for the Use of Point in Time Measures of Residence in Clinical Care. AB - Purpose: Interest is increasing in the use of geocoded patient address data to understand the effects that social determinants of health have on healthcare outcomes. Use of a patient's current address of record is often problematic given population mobility. Intragenerational economic mobility research suggests that patients will reside within neighborhoods with similar relative deprivation over time despite geographic mobility. The purpose of this study was to measure evidence of patient neighborhood deprivation persistence given a change in address of record. Methods: A retrospective cohort study of patients receiving active care in an integrated delivery system in a high-mobility United States region. Neighborhood deprivation was measured using a block-group level area deprivation index. Neighborhood deprivation persistence was measured as the probability that an individual with an address of record change remained within a neighborhood with a similar deprivation score. Logistic regression was used to conduct multivariate analysis. Results: Geographic mobility was highest among patients living in the most deprived neighborhoods versus least-deprived (odds ratio 1.75; 95% confidence interval: 1.71-1.79). Seventy-eight percent of all patients with a change of address did so to a neighborhood with a similar deprivation quintile. The probability that a random patient selected from the study had a change of address outside the same or neighboring quintile within a 1 year period ranged from 2% to 13%. Conclusions: Neighborhood deprivation persistence was high among this population of patients from a high mobility region. A current address of record is a reasonable indicator of patient exposure to neighborhood deprivation within a 1-3-year timeframe that is useful in evaluating healthcare disparities. PMID- 30283851 TI - The Complexities of Assessing Language and Interpreter Preferences in Pediatrics. AB - Providing patients, parents, and families high-quality healthcare in the language of their choice is a fundamental component of patient-centered care in pediatric settings. However, language needs may be complex and dynamic, creating clinical and ethical challenges in cases of provider-parent discordance regarding the need for an interpreter. In this perspectives article, we use a clinical encounter as a foundation to discuss the intricacies of addressing language needs in pediatrics. We also describe the urgent need for further innovation and improvement in linguistic supports available to diverse patients and families. PMID- 30283852 TI - Making the Case for Addressing Health Disparities: What Drives Providers and Payers? AB - Purpose: The creation of the Centers for Medicare & Medicaid Services Office of Minority Health placed increased emphasis on federal efforts to address health disparities. Although the literature establishes a social justice case for addressing health disparities, there is limited evidence of this case being sufficient for businesses to invest in such initiatives. The purpose of this study was to better understand the "business case" behind an organization's investment in health disparity reduction work. Methods: We conducted six case studies (44 on-site interviews) with diverse private-sector provider and payer organizations. Results: While providers and payers cited business rationales for initiating disparity-focused efforts, their motivations differed. Conclusion: As federal entities address health disparities, and payment models shift from volume to value, engaging private stakeholders with the leverage to move the health disparities needle is of principal importance. PMID- 30283853 TI - The Limited English Proficient Population: Describing Medicare, Medicaid, and Dual Beneficiaries. AB - Purpose: The Limited English Proficient (LEP) population experiences well documented suboptimal health outcomes and substandard provider experiences. The lack of national estimates on the size of the LEP population relative to the healthcare setting makes examining health outcomes for this population very difficult. This analysis addresses this limitation by publishing population estimates for LEP persons enrolled in Medicare, Medicaid, and Duals (enrolled in Medicare and Medicaid). Focusing on the Medicare and Medicaid programs provides an important foundation as these programs are not only the largest insurers in the United States but are also governed by legislation that requires LEP persons to receive equitable access to care. Methods: Data from the 2014 American Community Survey Public Use Microdata Sample (ACS PUMS) were used to produce national estimates and measures of statistical accuracy for the LEP population enrolled in Medicare and/or Medicaid (LEPMM). Results: In 2014, there were approximately 8.7 million LEP persons enrolled in Medicare, Medicaid, or both programs (Duals). The LEPMM was concentrated along the western and eastern coastlines and the southwestern region, with California and New York each containing more than 1 million LEPMMs. The LEPMM was also highly diverse with varying disability status, and most were racial or ethnic minorities and elderly. Conclusion: These findings provide a foundation for measuring an understudied and at-risk population that will enable population health professionals to develop effective culturally and linguistically, and appropriate services and policies that address health disparities in the LEPMM. PMID- 30283854 TI - The Beyond the Books Program: Improving Medical Student Attitudes Toward the Underserved. AB - Purpose: To determine the impact of the Beyond the Books (BTB) program, a short term pre-clinical intervention, on medical student attitudes toward the underserved (MSATU). Methods: BTB was evaluated through a prospective cohort study using the validated MSATU questionnaire. Results: There were no significant MSATU total score differences between BTB students (n=13) and student controls (n=29) at the beginning of the program. At the program's conclusion, BTB participant MSATU total scores were significantly higher than those of controls (p<0.001). Conclusion: Although limited by selection methods, our MSATU data support the capability of short-term pre-clinical interventions to significantly improve medical student attitudes toward underserved communities. PMID- 30283855 TI - Differences in Referral Access to Care Between Gastrointestinal Subspecialty Patients: Barriers and Opportunities. AB - Purpose: Referral access to subspecialty care for patients with gastrointestinal (GI) diseases is not well defined, but has significant importance to patients. We hypothesized that patients experience barriers to care in two common gastroenterology subspecialties, Hepatology and Motility, in a university medical center. Methods: Two hundred thirteen clinic patients (mean age 46.5 years; 66.5% female; 85.6% Caucasians) completed a formatted questionnaire on access to care. Hepatology patients were older (49.7 years, p=0.008); motility patients predominantly female (76.8%, p<0.001). Gender distribution was even for hepatology (51.2% female). Both groups were overweight (mean body mass index 28.4). Results: Patients waited a mean 89.5 days to be seen by a subspecialist. There were differences by subspecialty (107.6 days for motility vs. 64.3 days for hepatology, p=0.022). A larger percentage of motility patients were told nothing was wrong with them (16.8%, p<0.01) and could not be helped (42.1%, p=0.000). Conclusions: Access to care for subspecialty gastroenterology patients in a university center appears to be impacted by a number of variables. While there are similarities, differences exist between these two subspecialties. Motility patients were more likely to have been told they have nothing wrong with them, suffer setbacks financially, and suffer mood problems. Their wait time for appointments was also greater than hepatology patients. Further investigations of referral access for gastroenterology patients may yield additional insights into disease-specific barriers to accessing subspecialty care. PMID- 30283856 TI - Hispanic Breast Cancer Patients Travel Further for Equitable Surgical Care at a Comprehensive Cancer Center. AB - Purpose: Disparities in surgical breast cancer care have been documented for racial and ethnic minorities. On average, these minorities are less likely to utilize National Cancer Institute (NCI)-designated cancer centers and travel shorter distances to receive care. With the growing population of Hispanic patients in California, we analyzed the travel distance and surgical care of Hispanic and non-Hispanic patients at our large referral cancer center. Methods: Patients included were those who initiated treatment for a new diagnosis of ductal carcinoma in situ or invasive breast cancer at our NCI-designated cancer center during the period 2010-2014. Ethnicity was dichotomized as Hispanic and non-Hispanic. Google Maps were used to determine the distance from patient zip code to our institution, classified as 0-10, 10-30, 30-60, and >60 miles. Results: A total of 1765 non-Hispanic and 173 Hispanic patients were identified. Clinical stage by tumor size and nodal status were comparable between the two groups. Hispanic patients were younger (p<0.001) and more had Medicaid insurance (p<0.001). Hispanic patients traveled further when compared with non-Hispanics (p<0.001). In non-Hispanics and Hispanics, rates of breast conservation were 57.4% and 52.3% (p=0.30), unilateral mastectomy 34.2% and 36.2% (p=0.44), bilateral mastectomy 8.4% and 11.5% (p=0.24), and immediate postmastectomy reconstruction 42.6% and 50.6% (p=0.34), respectively. Hispanic ethnicity was not associated with different odds of receiving breast conservation (odds ratio [OR] 1.01, confidence interval [CI] 0.73-1.40), unilateral mastectomy (OR 1.05, CI 0.75-1.44), bilateral mastectomy (OR 1.37, CI 0.81-2.31), or immediate postmastectomy breast reconstruction (OR 1.27, CI 0.86-1.88), when compared with non-Hispanic ethnicity, after controlling for patient age, insurance status, and distance traveled. Conclusions: Surgical care was similar for Hispanic and non Hispanic patients treated at our NCI-designated cancer center. However, this Hispanic population traveled further than non-Hispanic patients. Our findings suggest that accessibility to transportation and institutional practices are instrumental in delivering equitable breast cancer surgical care for Hispanic patients. PMID- 30283857 TI - Equity Arguments in News Reporting on School Nutrition Policy. AB - Purpose: In two related studies, we examined how equity-based arguments featured in news debate over federal school nutrition policy. Methods: We conducted content analyses of national and local print and broadcast news (September 1, 2014-December 31, 2015), examining arguments rooted in appeals about equity and/or disparities. Results: Equity and/or disparities appeals appeared in 24% television, 14% national print, and 5% local print stories. Socioeconomic inequities were mentioned most; racial/ethnic inequities appeared minimally. Conclusions: Neither equity nor disparity featured prominently in this news debate over policy created to address children's nutritional inequities. When included, arguments focused on overcoming inequities' effects rather than addressing root causes. PMID- 30283858 TI - Sociodemographic Characteristics of Women Able to Obtain Medication Abortion Before and After Ohio's Law Requiring Use of the Food and Drug Administration Protocol. AB - Purpose: In 2011, a law went into effect in Ohio that regulates how abortion care providers can offer medication abortion to their patients. We sought to evaluate changes in sociodemographic characteristics of Ohio medication abortion patients before and after the implementation of this law. Methods: We used a retrospective cohort design, comparing characteristics of women obtaining a medication abortion at four abortion facilities before and after the law. We used chart data from January 2010 to January 2011 and February 2011 to October 2014. For any significant changes in sociodemographics found before and after the law, we used stratified cross-tabulations to disentangle whether they were likely related to the restricted gestational limit imposed by the law (lowered from 9 to 7 weeks gestation), or whether they were likely related to other burdens brought on by the law, such as increased costs and visits. Results: Women obtaining a medication abortion after the law were more likely to be older (p=0.01), have higher levels of education (p<0.001), be of white race (p<0.001), have private insurance (p=0.001), have no children (p=0.002), and reside in a higher income zip code (p=0.03). Both the reduced gestational limit and the increased costs and visits likely contributed to declines among black women and women with lower levels of education. The reduced gestational limit for medication abortion likely contributed to a decline among younger women and Medicaid recipient groups. The increased costs and visits imposed by the law likely contributed to the decline in medication abortion among women with no insurance and women with children. Conclusion: The lower gestational limit, higher cost, and time and travel burdens exacted by Ohio's medication abortion law were associated with disproportionate reductions in medication abortion among the most disadvantaged groups. The law was associated with reduced access among women who were younger, of black race, less educated, and in lower socioeconomic groups. PMID- 30283859 TI - Healthcare Experiences of Underrepresented Lesbian and Bisexual Women: A Focus Group Qualitative Study. AB - Purpose: To understand the complex healthcare experiences of women identifying as lesbian or bisexual. who are also women of color, veterans, and/or 65 years of age and older. Methods: Inclusion criteria were age 25 or older, Los Angeles County resident, self-identification as a lesbian or bisexual woman, and as an African American, Latina, Asian-Pacific Islander, and/or a veteran. For the age 65 years and older group, participants were eligible regardless of their veteran status or race/ethnicity. Five focus groups were conducted (n=35) and the same questions were asked addressing their comfort interacting with healthcare providers, the provider knowing their sexual orientation, characteristics of a perfect provider, and barriers to care. Structured qualitative analyses were performed. Results: Participants identified concerns that providers often hold to heterosexual cultural norms. Participants varied on preferences for providers of the same race/ethnicity as themselves. Lesbians who are 65 years and older identified legal barriers as major concerns. All groups identified incorrect provider assumptions about sexual orientation and sexual practices as frequently compromising their care. Participants supported the idea of certification for providers skilled in lesbian, gay, bisexual, transgender, and queer (LGBTQ) health, but expressed skepticism that such programs would necessarily result in better care. Conclusion: Healthcare provider trainings need to address the specific concerns and experiences of underrepresented lesbian and bisexual women. Healthcare environments must be transformed to effectively address their needs. More research is needed on the separate healthcare experiences of specific marginalized populations related to their sexual orientation and/or gender identity. PMID- 30283860 TI - Maternal Diet and Morbidity Factors Associated with Low Birth Weight in Haiti: A Case-Control Study. AB - Objective: A matched, case-control study was conducted to examine the association between development of low birth weight (LBW) and maternal factors, including dietary intake, comorbidities, and socioeconomic factors, among women in Cap Haitien, Haiti. Design: Mothers who delivered LBW babies; defined as <=2.5 kg, were identified by review of the medical record and matched to mothers of similar age, parity, with normal birth weight (NBW) babies. A survey was administered consisting of Women's Dietary Diversity Score (WDDS), maternal reporting of comorbidities, income, and educational level. Subjects: Women were eligible if they delivered and had newborns weighed within the last 2 years. Total study participants consisted of 32 cases and 34 controls matched for age, parity, and month of delivery. Results: Mothers who consume eggs were 78% less likely to have given birth to a LBW infant (OR 0.22 (95% CI: 0.05-0.87). Mothers with NBW babies had a nonsignificant trend towards higher WDDS. The prevalence of hypertension in mothers who were seen in the clinic at least once over the past 2 years was found to be 27%, and 78% of mothers were not aware of their diagnosis. Conclusion: Enhancing maternal nutrition during pregnancy has broad implications for reducing LBW, improving fetal health and reducing fetal predilection for chronic diseases in adulthood. Longitudinal prospective studies are needed to evaluate the selective benefit of eggs and other high-quality foods in protecting fetal growth. Efforts to improve knowledge and awareness of hypertension in Haiti should be undertaken.

The program aim was to increase lupus awareness by training high school students, community health workers, and parents. Methods: A curriculum was developed training POLs to disseminate concepts about lupus signs and symptoms. Pre- and post-program questions assessed lupus knowledge and message dissemination. Results: POL groups represented distinct demographic characteristics with Spanish or English language dominance. POLs reported increased lupus knowledge and program satisfaction. Conclusions: Future program goals should aim to increase understanding and improving access to care for Latino communities affected by lupus. PMID- 30283862 TI - Disparities in Cardiovascular Risk Factors in Northern Plains American Indians Undergoing Coronary Artery Bypass Grafting. AB - Objectives: Heart disease is the leading cause of death in American Indians (AIs). For AI patients with severe coronary artery disease requiring coronary artery bypass graft (CABG) surgery, little data exist. The purpose of this study was to evaluate short-term outcomes of Northern Plains AI undergoing CABG and identify variations in patient presentation. Methods: All patients undergoing isolated CABG between June 2012 and June 2017 were studied. Seventy-four AI and 1236 non-American Indian (non-AI) patients were identified. Risk factors, preoperative characteristics, cardiac status, procedural information, and outcomes were collected. Univariate analysis comparing short-term clinical outcomes between AI and non-AI populations was performed. Multivariable logistic regression models were constructed and outcome differences assessed. Unadjusted Kaplan-Meier survival estimates were produced using 5-year survival data. Results: AI patients presented with increased risk factors, including higher rates of diabetes mellitus (AI 63.5% vs. non-AI 38.7% p=< 0.001) and smoking/tobacco use (AI 60.8% vs. non-AI 20.0% p=> 0.001). Seventy-nine percent of AI patients resided on or near federal reservations and presented from rural locations. Internal mammary artery (IMA) graft use in both groups was high (AI 95.9% vs. non-AI 94.9% p=0.904), and multiarterial grafting with left internal mammary artery and radial artery use was common in both groups (AI 67.6% vs. non AI 69.6% p=0.814). No significant differences in unadjusted 30-day mortality or short-term outcomes were detected. Adjusted Kaplan-Meier survival curves were similar between race groups up through 5 years after CABG (p-value=0.38). Conclusion: AIs presented with significantly more risk factors for cardiovascular disease compared with the general population, with especially high rates of insulin-dependent diabetes and active tobacco use. Despite this, outcomes were similar between groups. In propensity-matched groups, AIs were at decreased risk for prolonged length of stay and combined morbidity/mortality. In contrast to previous reports, AI racial identity did not adversely affect survival up to 5 years after CABG. PMID- 30283863 TI - Internet Access Influences Community Clinic Portal Use. AB - Purpose: To assess whether individuals attending a community clinic had the necessary Internet access and experience to use the patient portal, while examining covariates of education, income, and self-perception of health with past and anticipated portal use. Methods: Adults attending an urban, community primary care clinic were invited to participate in a brief survey assessing current Internet access and use, past portal use, and anticipated future portal use. Survey responses were analyzed using descriptive and multivariate statistics. Results: One hundred fifteen participants ranging in age from 18 to 84 years (mean 42.1, standard deviation 17.1) completed the survey; 6 (5%) in Spanish. Thirty-five (30%) self-identified as Latino; 12 (10%) as Asian; and 20 (17%) as other. Almost 80% reported their health as good or better. Although 38% reported some college and 47% reported being college graduates, 60% reported household incomes were <$50,000. Most (87%) used the Internet for >1 year. Fewer than half (42%) had past portal use, with significant differences associated with weekly Internet use (Fisher's exact=9.59; p=0.02) and smart phone access (Fisher's exact=6.15; p=0.02). Computer Internet access was significantly associated with income (Fisher's exact=16.91; p<0.001). Logistic regression identified that computer Internet access was a significant predictor (odds ratio 9.9 (95% confidence interval: 1.7-58.8) of future portal use, controlling for smart phone use, health status, gender, and age. Conclusions: Among this highly educated but lower economic sample, computer Internet access and smart phone access were associated with past portal use and anticipated future use. PMID- 30283864 TI - Developing Smokeless Tobacco Prevention Messaging for At-Risk Youth: Early Lessons from "The Real Cost" Smokeless Campaign. AB - Introduction: Smokeless tobacco (SLT) use continues to be a significant public health challenge in the United States, particularly among young males in rural areas, where use remains disproportionately high. In support of the U.S. Food and Drug Administration's first nationwide SLT public education campaign, formative research was conducted to inform campaign strategy development and test creative concepts. Methods: Qualitative research methods were used to inform the strategic direction of the campaign, identify salient message themes, and refine creative concepts. Focus groups were conducted with 252 rural male youth ages 12-17 in seven states. Groups were organized by SLT status (i.e., at-risk for initiating vs. experimenting with SLT) and age group. Results: SLT use is culturally ingrained in rural communities, and rural youth are commonly exposed to SLT through close relationships. Among this group, "dipping" (SLT use) has strong cultural significance and is perceived as safe. Members of the target audience are receptive to straightforward facts delivered by authentic messengers about the potentially harmful consequences of SLT use, specifically those that leverage the progression of short-term consequences (e.g., white patches) to long-term health effects. Conclusions: This study addresses SLT literature gaps related to youth knowledge, attitudes, and beliefs by summarizing audience learnings from formative research that was used to develop the first national SLT public education campaign. PMID- 30283865 TI - The Application of Medical Artificial Intelligence Technology in Rural Areas of Developing Countries. AB - Background: Artificial intelligence (AI) is a rapidly developing computer technology that has begun to be widely used in the medical field to improve the professional level and efficiency of clinical work, in addition to avoiding medical errors. In developing countries, the inequality between urban and rural health services is a serious problem, of which the shortage of qualified healthcare providers is the major cause of the unavailability and low quality of healthcare in rural areas. Some studies have shown that the application of computer-assisted or AI medical techniques could improve healthcare outcomes in rural areas of developing countries. Therefore, the development of suitable medical AI technology for rural areas is worth discussing and probing. Methods: This article reviews and discusses the literature concerning the prospects of medical AI technology, the inequity of healthcare, and the application of computer-assisted or AI medical techniques in rural areas of developing countries. Results: Medical AI technology not only could improve physicians' efficiency and quality of medical services, but other health workers could also be trained to use this technique to compensate for the lack of physicians, thereby improving the availability of healthcare access and medical service quality. This article proposes a multilevel medical AI service network, including a frontline medical AI system (basic level), regional medical AI support centers (middle levels), and a national medical AI development center (top level). Conclusion: The promotion of medical AI technology in rural areas of developing countries might be one means of alleviating the inequality between urban and rural health services. The establishment of a multilevel medical AI service network system may be a solution. PMID- 30283866 TI - Chinese Immigrant Women's Attitudes and Beliefs About Family Involvement in Women's Health and Healthcare: A Qualitative Study in Chicago's Chinatown. AB - Purpose: Healthcare utilization and health-seeking behaviors of Chinese American immigrant women may be influenced by longstanding cultural perspectives of family roles and relationships. An understanding of Chinese immigrant women's perceptions of family social support in health and how these beliefs manifest in healthcare utilization and help-seeking behaviors is critical to the development of culturally appropriate health interventions. Focusing on a sample of Chinese women in Chicago's Chinatown, this qualitative study seeks to describe women's attitudes and beliefs about spouse and adult children's involvement in women's health and healthcare. Methods: We conducted six focus groups among 56 Chinese speaking adult women in Chicago's Chinatown between July and August 2014. Focus groups were transcribed, coded, and analyzed for emergent themes. Results: Women reported that their adult children supported their health and healthcare utilization by helping them overcome language and transportation barriers, making and supporting decisions, and providing informational and instrumental support related to diet and nutrition. Women viewed these supports with mixed expectations of filial piety, alongside preferences to limit dependency and help seeking because of concern and emotional distress regarding burdening adult children. Women's expectations of the spouse involvement in their healthcare were low and were shaped by avoidance of family conflict. Conclusion: Findings inform opportunities for the development of culturally appropriate interventions to enhance Chinese immigrant women's health and healthcare. These include patient navigation/community health worker programs to promote self-management of healthcare and family-centered strategies for enhancing family social support structures and reducing family conflict. PMID- 30283867 TI - Racial Disparities and the Effect of County Level Income on the Incidence and Survival of Young Men with Anal Cancer. AB - Purpose: Prior studies have identified a racial disparity in incidence and survival of squamous cell carcinoma of the anus (SCCA) in the young African American male population. We aim to determine whether racial disparities are independent of income and urban location. Methods: The National Cancer Institute's Surveillance of Epidemiology and End Results database was queried for data on patients with SCCA for the years of 2000-2013. Cox regression was used to determine the effect of race, county median family income, rural-urban continuum, and stage of disease on overall survival. Results: The incidence rate of SCCA was significantly higher in black men <50 years old than in white men. Black race had a hazard ratio of 1.55 (confidence interval [CI] 1.33-1.81) when controlling for age, stage, income, and urban-rural status. Each $10,000 increase in county median family income was protective with a hazard ratio of 0.90 (CI 0.86-0.94). Residence in a metropolitan area did not significantly affect survival. Conclusions: The lower survival of black men <50 years old with SCCA is independent of income, urban location, and stage of disease. Further efforts are needed to target this at-risk population and the authors suggest wide application of previously validated screening programs for anal dysplasia. PMID- 30283869 TI - Provision of Reproductive Healthcare to Women with Disabilities: A Survey of Obstetrician-Gynecologists' Training, Practices, and Perceived Barriers. AB - Purpose: The purpose of this study was to document current awareness, attitudes, and training regarding the care of women with disabilities by obstetrician gynecologists (ob-gyns) and explore barriers that may explain observed discrepancies in care. Methods: One thousand ob-gyns, including 500 members of the Collaborative Ambulatory Research Network (CARN), were surveyed on practice accessibility, training, awareness, barriers, beliefs, comfort, challenges, practices, contraceptive counseling, and preconception/pregnancy counseling. Results: CARN, 49.0%, and non-CARN, 19.4%, members completed the survey for an overall response rate of 33.9%. Most respondents indicated feeling "somewhat" (57.5%) or "very" (21.9%) aware of the special healthcare needs of women with disabilities. Only 17.2%, however, received any information or training on the provision of healthcare to women with disabilities. Eighty-one percent agreed somewhat or strongly that women with disabilities are less likely to receive comprehensive reproductive healthcare. Respondents who provided contraceptive counseling (94.3%) initiated it with women of reproductive age who did not have a disability more frequently than those who had a disability. Finally, only 19.3% felt "definitely" adequately equipped to manage the pregnancies of women with disabilities. Conclusion: Women with disabilities require reproductive healthcare no less than women without disabilities; however, the evidence consistently identifies disparities. This study suggests that while ob-gyn providers are aware of these issues, they lack adequate training and resources to provide equal care. PMID- 30283868 TI - Alternatives in Assessing Mental Healthcare Disparities Using the Behavioral Risk Factor Surveillance System. AB - Purpose: Identification of mental healthcare disparities through scales or questionnaires is an initial step to improve mental healthcare equity. This study was designed to investigate the performance of a single-item question relative to two psychiatric scales with multiple items in assessing mental healthcare disparities among U.S. adults using the Behavioral Risk Factor Surveillance System (BRFSS) data. Methods: The current depression (CD) and serious psychological distress (SPD) were analyzed in 2010 and 2012 with the BRFSS using two multiple-item scales in selected states. Receipt of mental health diagnosis and mental health treatment was ascertained respectively. In both years, a single item of the number of mentally unhealthy days from Centers for Disease Control Health-Related Quality of Life-4 (CDC-HRQOL-4) core questions was used to ascertain frequent mental distress (FMD) in all states. Logistic regression was used to identify mental healthcare disparities among subpopulations. The t-test was used to analyze missing data patterns. Results: Among adults who experienced FMD or CD in 2010, men, persons 65 years of age or older, non-Hispanic Blacks, persons who were currently or never married, and persons who were employed had a lower likelihood of receiving diagnosis of depression. Among adults who experienced FMD or SPD in 2012, men, persons 65 years of age or older, Hispanics and Blacks, persons who were currently employed or homemakers/students, and persons without healthcare coverage had a lower likelihood to receive mental health treatment. The missing rates of FMD were 1.8% (2010) and 1.4% (2012), while the missing rates of Patient Health Questionnaire 8 (PHQ-8) and Kessler 6 (K6) were 12.8% (2010) and 17.4% (2012). The samples with missing data were different from those without. Conclusions: The single-item question is a valuable alternative in a large population surveillance to identify vulnerable subpopulations for lower mental health diagnosis and treatment. PMID- 30283870 TI - Barriers to Mental Health Treatment Utilization in Wards 7 and 8 in Washington, DC: A Qualitative Pilot Study. AB - Purpose: There is a paucity of data on barriers to mental health treatment utilization among residents of Wards 7 and 8 in Washington, DC, despite exposure to many environmental factors that are associated with poor mental health outcomes and the high prevalence of mental health problems among residents. The objective of this study was to examine barriers to mental healthcare utilization among residents of Wards 7 and 8. Methods: This study included semi-structured, in-depth interviews with five key informants who lived or spent significant time in Wards 7 or 8 in Washington, DC, which are the wards served by Paving the Way MSI, a behavioral health clinic that served as a partner organization in the study. Results: Barriers to mental health treatment utilization existed at a variety of social-ecological levels, including the individual/interpersonal level, the provider/mental health system level, the community level, and the societal level. Major barriers included fear and trust/distrust in the medical system, lack of social support, the model of mental healthcare, lack of patient centered care, limited access to mental health services, stigma of mental illness and mental health treatment, and poverty. Conclusion: This study highlights the need to address barriers to mental health treatment utilization at multiple social-ecological levels. Future studies should examine perspectives from residents with mental health problems in these wards to gain a more thorough understanding of the barriers to treatment. Funding is needed to support efforts to increase mental health treatment utilization among residents of Wards 7 and 8. PMID- 30283871 TI - Factors Associated with Human Papillomavirus Vaccination Among Diverse Adolescents in a Region with Low Human Papillomavirus Vaccination Rates. AB - Introduction: This study assesses the sociodemographic facilitators and barriers to human papillomavirus (HPV) vaccination for diverse teens in a region with low HPV vaccination rates. Materials and Methods: In this community-based participatory research study, we surveyed adult family members of teens aged 11 17 years from African American, African refugee, American Indian/Alaskan Native, Hispanic/Latino, and Native Hawaiian/Pacific Islander community groups in Salt Lake City, Utah. Bivariate analyses assessed associations between sociodemographic characteristics and, respectively, HPV vaccine receipt and intentions for vaccination. Barriers to vaccination were also investigated. Results: Only 20% of participants had vaccinated at least one of their children with at least one dose of the HPV vaccine. HPV vaccination was significantly related to caregiver age (p=0.035), race/ethnicity (p=0.001), educational attainment (p=0.006), annual household income (p=0.0454), years in the United States (p=0.023), and caregiver parent birthplace (p=0.008). Among caregivers with unvaccinated children, intention to vaccinate was significantly related to race/ethnicity (p=0.048 for daughters; p=0.003 for sons), caregiver parent birthplace (p=0.023 for sons), health insurance coverage (p=0.028 for daughters; p=0.047 for sons), and type of health insurance coverage (p=0.008 for sons). The most frequently cited barriers to HPV vaccination were lack of knowledge about the HPV vaccine, costs, side effects, and child not being sexually active. Conclusions: Our results show substantially lower HPV vaccine coverage than both national and state rates, signaling the urgent need for multipronged HPV vaccination interventions within these communities; strategies are discussed. PMID- 30283872 TI - Importance of Shared Decision-Making for Vulnerable Populations: Examples from Postmastectomy Breast Reconstruction. AB - Shared decision-making (SDM) is a process through which patients and providers collaborate to select a treatment option that aligns with patients' preferences and clinical context. SDM can improve patients' decision quality and satisfaction. However, vulnerable populations face barriers to participation in SDM, which exacerbates disparities in decision quality. This perspective article discusses SDM with vulnerable patients, using examples from patients who made decisions about postmastectomy breast reconstruction. We offer several strategies for clinical practice, medical education, and research to ensure that movements to engage patients in SDM do not exclude already marginalized groups. PMID- 30283873 TI - It Works, But For Whom? Examining Racial Bias in Carding Experiences and Acceptance of a County Identification Card. AB - Purpose: Policies that restrict access to U.S. government-issued photo identification (ID) cards adversely affect multiple marginalized communities. This context impedes access to health-promoting resources that increasingly require government-issued IDs and exacerbates health inequities. In 2015, Washtenaw County, Michigan, implemented the Washtenaw ID to improve access to resources contingent upon having an ID. We employed an audit study to examine whether Washtenaw ID users experienced racially biased treatment in carding experiences and acceptance of the Washtenaw ID. Methods: Seven 25- to 32-year-old mystery shoppers (two Latina, three black, and two white women) attempted to purchase a standardized basket of goods, including an age-restricted item in Washtenaw County stores (n=130 shopping experiences). We examined whether experiences of being asked for ID and acceptance of the Washtenaw ID varied by race/ethnicity. Results: Each shopper visited 9-22 stores. Shoppers were asked for ID in 63.1% of shopping experiences. Of these, the Washtenaw ID was accepted 91.5% of the time. Among those who were asked for ID, a higher percentage of Latina (16.0%) shoppers had their Washtenaw IDs rejected than black (6.3%) and white (4.0%) shoppers, although differences were not statistically significant (p=0.27). Latina shoppers had 2.9 times the odds of receiving a comment about their Washtenaw ID relative to white shoppers (OR=2.92, p=0.08), comments that were nonpositive. Conclusion: Local IDs may improve access to resources contingent upon having an ID. However, racialization processes, including anti immigrant sentiments, may inhibit the mitigating goal of local IDs. Continued attention to the health equity impacts of equity-driven interventions is warranted. PMID- 30283875 TI - Rural-Urban Differences in Risk Factors for Motor Vehicle Fatalities. AB - Purpose: To examine rural-urban differences in motor vehicle fatality (MVF) risk factors. Methods: We used 2017 County Health Rankings data to run stratified regression models to estimate county-level correlates of motor vehicle fatalities (MVFs) by rural and urban location. Results: Rural counties have higher rates of MVFs than urban counties (22 vs. 14 per 100,000, p<0.001). Physical inactivity and uninsurance were associated with higher rates of MVFs, as was having a more racially or ethnically concentrated population and larger percentages of younger or older adults. Conclusion: Interventions to reduce MVFs should take geographic location and population composition into account. PMID- 30283876 TI - The Birth of JBMR Plus. PMID- 30283874 TI - Racism, African American Women, and Their Sexual and Reproductive Health: A Review of Historical and Contemporary Evidence and Implications for Health Equity. AB - Background: The sexual and reproductive health of African American women has been compromised due to multiple experiences of racism, including discriminatory healthcare practices from slavery through the post-Civil Rights era. However, studies rarely consider how the historical underpinnings of racism negatively influence the present-day health outcomes of African American women. Although some improvements to ensure equitable healthcare have been made, these historical influences provide an unexplored context for illuminating present-day epidemiology of sexual and reproductive health disparities among African American women. Methods: To account for the unique healthcare experiences influenced by racism, including healthcare provision, we searched online databases for peer reviewed sources and books published in English only. We explored the link between historical and current experiences of racism and sexual and reproductive health outcomes. Results: The legacy of medical experimentation and inadequate healthcare coupled with social determinants has exacerbated African American women's complex relationship with healthcare systems. The social determinants of health associated with institutionalized and interpersonal racism, including poverty, unemployment, and residential segregation, may make African American women more vulnerable to disparate sexual and reproductive health outcomes. Conclusions: The development of innovative models and strategies to improve the health of African American women may be informed by an understanding of the historical and enduring legacy of racism in the United States. Addressing sexual and reproductive health through a historical lens and ensuring the implementation of culturally appropriate programs, research, and treatment efforts will likely move public health toward achieving health equity. Furthermore, it is necessary to develop interventions that address the intersection of the social determinants of health that contribute to sexual and reproductive health inequities. PMID- 30283878 TI - Bilateral Avascular Necrosis of the Femoral Head in Fibrous Dysplasia. AB - Fibrous dysplasia (FD) is an uncommon benign skeletal disorder, characterized by bone pain, deformities, and the development of pathological fractures. It is caused by osteoblastic lineage differentiation defects, leading to the replacement of normal bone with benign disorganized fibrous connective tissue. Avascular necrosis (AVN) of the femoral head is an insidious condition that can often be challenging to diagnose in its early stages. The pathogenesis of AVN is not well understood; however, it causes femoral head ischemia and collapse, often requiring hip arthroplasty. We report the first case of FD and bilateral AVN of the femoral head in the absence of an antecedent fracture. We postulate several mechanisms to explain how FD may result in AVN; however, further research is required to understand its pathophysiology and thus to guide clinical practice. (c) 2017 The Authors.

PMID- 30283877 TI - Identification of Chloride Intracellular Channel Protein 3 as a Novel Gene Affecting Human Bone Formation. AB - Osteoporosis is a common skeletal disorder characterized by low bone mass leading to increased bone fragility and fracture susceptibility. The bone building cells, osteoblasts, are derived from mesenchymal stromal cells (MSCs); however, with increasing age osteogenic differentiation is diminished and more adipocytes are seen in the bone marrow, suggesting a shift in MSC lineage commitment. Identification of specific factors that stimulate osteoblast differentiation from human MSCs may deliver therapeutic targets to treat osteoporosis. The aim of this study was to identify novel genes involved in osteoblast differentiation of human bone marrow-derived MSCs (hMSCs). We identified the gene chloride intracellular channel protein 3 (CLIC3) to be strongly upregulated during MSC-derived osteoblast differentiation. Lentiviral overexpression of CLIC3 in hMSCs caused a 60% increase of matrix mineralization. Conversely, knockdown of CLIC3 in hMSCs using two short-hairpin RNAs (shRNAs) against CLIC3 resulted in a 69% to 76% reduction in CLIC3 mRNA expression, 53% to 37% less alkaline phosphatase (ALP) activity, and 78% to 88% less matrix mineralization compared to scrambled control. Next, we used an in vivo human bone formation model in which hMSCs lentivirally transduced with the CLIC3 overexpression construct were loaded onto a scaffold (hydroxyapatite-tricalcium-phosphate), implanted under the skin of NOD SCID mice, and analyzed for bone formation 8 weeks later. CLIC3 overexpression led to a 15-fold increase in bone formation (0.33% versus 5.05% bone area relative to scaffold). Using a Clic3-His-tagged pull-down assay and liquid chromatography-mass spectrometry (LS/MS)-based proteomics analysis in lysates of osteogenically differentiated hMSCs, we showed that CLIC3 interacts with NIMA related kinase 9 (NEK9) and phosphatidylserine synthase 1 (PTDSS1) in vitro, and this finding was supported by immunofluorescent analysis. In addition, inhibition of NEK9 or PTDSS1 gene expression by shRNAs inhibited osteoblast differentiation and mineralization. In conclusion, we successfully identified CLIC3 to be a lineage-specific gene regulating osteoblast differentiation and bone formation through its interaction with NEK9 and PTDSS1. (c) The Authors.

PMID- 30283879 TI - Influence of Dosing Interval and Administration on the Bone Metabolism, Skeletal Effects, and Clinical Efficacy of Parathyroid Hormone in Treating Osteoporosis: A Narrative Review. AB - Recombinant human parathyroid hormone (PTH) is the key anabolic agent used for preventing fracture in postmenopausal women with osteoporosis. In bone metabolism, PTH signaling is mediated through a G protein-coupled receptor that affects various post-receptor signaling pathways. Results of preclinical and clinical studies have shown that PTH improves both the structure and strength of bone tissue. Once daily subcutaneous injection of the PTH fragment, teriparatide (PTH [1-34]), is the most commonly recommended formulation and dosing strategy in clinical practice. However, other dosing intervals, formulations, and routes have been investigated in preclinical and clinical studies. In particular, once-weekly and cyclical administration have been investigated mainly as a means of reducing the high direct costs of treatment. In preclinical studies, bone formation/resorption markers, bone mineral density measurements, and histomorphometric parameters improved with both once-daily and once-weekly administration. However, the magnitude and duration of such improvements were generally greater with once-daily PTH administration. In clinical studies, reductions in fracture incidence were also noted with both once-daily and once weekly PTH administration, although improvements in nonvertebral fractures are less evident with once-weekly administration. This narrative review details the differences between PTH formulation and dosing strategies in relation to preclinical and clinical efficacy/safety parameters, although it should be stressed that no head-to-head studies allow direct comparisons. This review also seeks to outline practical considerations involved with PTH prescribing and new directions in research regarding routes of administration. (c) 2017 The Authors.

PMID- 30283880 TI - The CRH-Transgenic Cushingoid Mouse Is a Model of Glucocorticoid-Induced Osteoporosis. AB - Glucocorticoids (GCs) have unparalleled anti-inflammatory and immunosuppressive properties, which accounts for their widespread prescription and use. Unfortunately, a limitation to GC therapy is a wide range of negative side effects including Cushing's syndrome, a disease characterized by metabolic abnormalities including muscle wasting and osteoporosis. GC-induced osteoporosis occurs in 30% to 50% of patients on GC therapy and thus, represents an important area of study. Herein, we characterize the molecular and physiologic effects of GC-induced osteoporosis using the Cushing's mouse model, the corticotropin releasing hormone (CRH) transgenic mouse (CRH-Tg). The humeri, femurs, and tibias from wild-type (WT) and CRH-Tg male mice, aged 13 to 14 weeks old were subjected to multiple bone tests including, micro-computed tomography (MUCT), static and dynamic histomorphometry, strength testing, and gene expression analyses. The CRH Tg mice had a 38% decrease in cortical bone area, a 35% decrease in cortical thickness, a 16% decrease in trabecular thickness, a sixfold increase in bone adiposity, a 27% reduction in osteoid width, a 75% increase in bone-resorbing osteoclast number/bone surface, a 34% decrease in bone formation rate, and a 40% decrease in bone strength compared to WT mice. At the gene expression level, CRH Tg bone showed significantly increased osteoclast markers and decreased osteoblast markers, whereas CRH-Tg muscle had increased muscle atrophy gene markers compared to WT mice. Overall, the CRH-Tg mouse model aged to 14 weeks recapitulated many features of osteoporosis in Cushing's syndrome and thus, represents a useful model to study GC-induced osteoporosis and interventions that target the effects of GCs on the skeleton.

PMID- 30283881 TI - Interactions of Phosphate Metabolism With Serious Injury, Including Burns. AB - Approximately 85% of the body's phosphate pool resides within the skeleton. The remaining 15% is stored as high-energy phosphates or in its free form, where it acts as a substrate for adenosine triphosphate (ATP) production. Accordingly, phosphate plays a crucial role in energy metabolism. Trauma and critical illness result in a hypermetabolic state in which energy expenditure increases. The impact of trauma and critical illness on the body's phosphate stores and phosphate-dependent metabolic reactions is poorly understood. We had previously observed that after severe burn trauma, increased energy expenditure is temporally related to a marked reduction in serum concentrations of both parathyroid hormone and fibroblast growth factor 23, both of which have phosphaturic effects. The aim of this article is to describe as far as is known the similarities and differences in phosphate metabolism in different types of injury and to infer what these differences tell us about possible signaling pathways that may link increased phosphate utilization and phosphate retention.

PMID- 30283882 TI - Treatment With a Soluble Bone Morphogenetic Protein Type 1A Receptor (BMPR1A) Fusion Protein Increases Bone Mass and Bone Formation in Mice Subjected to Hindlimb Unloading. AB - Previous work has shown that the soluble murine BMPR1A-fusion protein (mBMPR1A mFc) binds to BMP2 and BMP4 with high affinity, preventing downstream signaling. Further, treatment of intact and ovariectomized mice with mBMPR1A-mFc leads to increased bone mass, and improved bone microarchitecture and strength, via increased bone formation and reduced resorption. In this study, we tested the effects of mBMPR1A-mFc on disuse-induced bone loss caused by 21 days of hindlimb unloading (HLU) via tail suspension versus cage controls (CONs). Adult female C57BL/6J mice (12 weeks old) were assigned to one of four groups (n = 10 each): CON-VEH; CON-mBMPR1A-mFc; HLU-VEH; and HLU-mBMPR1A-mFc. Mice were injected subcutaneously with VEH or mBMPR1A-mFc (4.5 mg/kg, 2*/week). Leg BMD declined in the HLU-VEH group (-5.3% +/- 1.3%), whereas it was unchanged in HLU-mBMPR1A-mFc ( 0.3% +/- 0.9%, p < 0.05 versus HLU-VEH). Leg BMD increased significantly more in CON-mBMPR1A-mFc than CON-VEH (10.2% +/- 0.6% versus 4.4% +/- 0.8%). In the femur, trabecular, and cortical bone microarchitecture was worse in the HLU-VEH compared to CON-VEH mice, whereas mBMPR1A-mFc treatment for 3 weeks led to greater Tb.BV/TV, Tb.Th, and midshaft Ct.Th in both the HLU and CON groups compared to comparable VEH-treated counterparts (p < 0.05). HLU-mBMPR1A-mFc mice also had 21% greater failure load (p < 0.05) compared to their VEH-treated counterparts. Dynamic histomorphometry indicated that treatment with mBMPR1A-mFc led to significantly greater mineralizing surface and mineral apposition rate, resulting in a 3.5-fold and fivefold higher bone formation rate in the mBMPR1A-mFc-treated CON and HLU animals versus VEH groups, respectively. mBMPR1A-mFc-treated mice had a similar osteoblast surface but significantly lower osteoclast surface than VEH treated animals in both the CON and HLU groups. Altogether, these findings suggest that treatment with the soluble BMPR1A fusion protein may be useful for maintenance of skeletal integrity in the setting of disuse-induced bone loss. PMID- 30283883 TI - Improvement of Giant Cell Lesions of the Jaw Treated With High and Low Doses of Denosumab: A Case Series. AB - Giant cell tumors (GCTs) and central giant cell granulomas (CGCGs) are aggressive lesions that appear in the jaw. These lesions occur in the second and third decades of life and often arise in the mandible. Clinical manifestations of these lesions vary from asymptomatic to symptomatic tooth displacement with cortical perforation. GCTs, which are characterized by multinucleated osteoclast-type giant cells that express receptor activator of nuclear factor-kappaB (RANK) ligand, rarely present in the jaw and have overlapping histopathologic features with CGCGs, which are composed of fibroblastic stromal cell lesions. GCTs and CGCGs have overlying histopathologic features that make distinction between the two challenging. There is a real controversy as to whether giant cell tumors and central giant cell granulomas are in fact, one and the same lesion. The majority of GCTs occur in the long bone, with surgery being the typical therapeutic option. Denosumab as a treatment modality is a fairly new concept that has been used effectively in GCTs affecting long bones. There is less experience, however, with its use for jaw lesions. This seven-case series describes the effective use of both low-dose and high-dose denosumab in the treatment of GCTs and CGCGs affecting the jaw and special dosing considerations for younger patients who present with disease.

PMID- 30283884 TI - Is Retinal Microvascular Abnormalities an Independent Risk Factor of Vertebral Fractures? A Prospective Study From a Chinese Population. AB - Low bone mineral density (BMD) and microvascular diseases (MVD) share various common risk factors; however, whether MVD is an independent risk factor of vertebral fractures is incompletely understood. The aim of this study is to clarify whether MVD is an independent risk factor of vertebral fractures. In this prospective study, calcaneal BMD and retinal microvascular abnormalities were assessed at baseline from June 2011 to January 2012. A total of 2176 premenopausal women, 2633 postmenopausal women, 2998 men aged <65 years, and 737 men aged >=65 were included. Then with/without retinal microvascular abnormalities cohorts were followed for an average of 2.93 years to find out the relationship between MVD and vertebral fractures. At the baseline, after full adjustment, retinal microvascular abnormalities were related to risk of low BMD only in men aged >=65 years (odds ratio [OR] = 2.506; 95% confidence interval [CI] 1.454-4.321; p = 0.001). After follow-up of 2.93 years, retinal microvascular abnormalities were related to risk of vertebral fractures in men aged >=65 years (OR = 2.475; 95% CI 1.085-5.646; p = 0.031) when adjustment for confounding factors. However, no associations were found between MVD and vertebral fractures in men aged <65 years, premenopausal women, and postmenopausal women. When stratified by diabetes, in the without-diabetes group, the men with retinal microvascular abnormalities had higher risk for vertebral fractures than without retinopathy (OR = 2.194; 95% CI 1.097-4.389; p = 0.026); however, the difference was not found in women. In the diabetes group, there were no significant differences of risk for vertebral fractures between those with retinal microvascular abnormalities and those without both in men and women. Stratified by hypertension, the men with retinopathy had higher risk for vertebral fractures than those without among the hypertension group (OR = 2.034; 95% CI 1.163-3.559; p = 0.013), but a difference was not found among women. In the without-hypertension group, no relation was found between MVD and fracture both in men and women. In conclusion, MVD is an independent risk factor of vertebral fractures in old men.

PMID- 30283885 TI - Insulin-Stimulated Bone Blood Flow and Bone Biomechanical Properties Are Compromised in Obese, Type 2 Diabetic OLETF Rats. AB - Type 2 diabetes (T2D) increases skeletal fragility and fracture risk; however, the underlying mechanisms remain to be identified. Impaired bone vascular function, in particular insulin-stimulated vasodilation and blood flow is a potential, yet unexplored mechanism. The purpose of this study was to determine the effects of T2D on femoral biomechanical properties, trabecular microarchitecture, and insulin-stimulated bone vasodilation by comparison of hyperphagic Otsuka Long-Evans Tokushima Fatty (OLETF) rats with normoglycemic control OLETF rats. Four-week old, male OLETF rats were randomized to two groups: type 2 diabetes (O-T2D) or normoglycemic control (O-CON). O-T2D were allowed ad libitum access to a rodent chow diet and O-CON underwent moderate caloric restriction (30% restriction relative to intake of O-T2D) to maintain normal body weight (BW) and glycemia until 40 weeks of age. Hyperphagic O-T2D rats had significantly greater BW, body fat, and blood glucose than O-CON. Total cross sectional area (Tt.Ar), cortical area (Ct.Ar), Ct.Ar/Tt.Ar, and polar moment of inertia of the mid-diaphyseal femur adjusted for BW were greater in O-T2D rats versus O-CON. Whole-bone biomechanical properties of the femur assessed by torsional loading to failure did not differ between O-T2D and O-CON, but tissue level strength and stiffness adjusted for BW were reduced in O-T2D relative to O CON. Micro-computed tomography (MUCT) of the distal epiphysis showed that O-T2D rats had reduced percent bone volume, trabecular number, and connectivity density, and greater trabecular spacing compared with O-CON. Basal tibial blood flow assessed by microsphere infusion was similar in O-T2D and O-CON, but the blood flow response to insulin stimulation in both the proximal epiphysis and diaphyseal marrow was lesser in O-T2D compared to O-CON. In summary, impaired insulin-stimulated bone blood flow is associated with deleterious changes in bone trabecular microarchitecture and cortical biomechanical properties in T2D, suggesting that vascular dysfunction might play a causal role in diabetic bone fragility.

PMID- 30283886 TI - Genetic Risk Factors for Atypical Femoral Fractures (AFFs): A Systematic Review. AB - Atypical femoral fractures (AFFs) are uncommon and have been associated particularly with long-term antiresorptive therapy, including bisphosphonates. Although the pathogenesis of AFFs is unknown, their identification in bisphosphonate-naive individuals and in monogenetic bone disorders has led to the hypothesis that genetic factors predispose to AFF. Our aim was to review and summarize the evidence for genetic factors in individuals with AFF. We conducted structured literature searches and hand-searching of conference abstracts/reference lists for key words relating to AFF and identified 2566 citations. Two individuals independently reviewed citations for (i) cases of AFF in monogenetic bone diseases and (ii) genetic studies in individuals with AFF. AFFs were reported in 23 individuals with the following 7 monogenetic bone disorders (gene): osteogenesis imperfecta (COL1A1/COL1A2), pycnodysostosis (CTSK), hypophosphatasia (ALPL), X-linked osteoporosis (PLS3), osteopetrosis, X linked hypophosphatemia (PHEX), and osteoporosis pseudoglioma syndrome (LRP5). In 8 cases (35%), the monogenetic bone disorder was uncovered after the AFF occurred. Cases of bisphosphonate-naive AFF were reported in pycnodysostosis, hypophosphatasia, osteopetrosis, X-linked hypophosphatemia, and osteoporosis pseudoglioma syndrome. A pilot study in 13 AFF patients and 268 controls identified a greater number of rare variants in AFF cases using exon array analysis. A whole-exome sequencing study in 3 sisters with AFFs showed, among 37 shared genetic variants, a p.Asp188Tyr mutation in the GGPS1 gene in the mevalonate pathway, critical to osteoclast function, which is also inhibited by bisphosphonates. Two studies completed targeted ALPL gene sequencing, an ALPL heterozygous mutation was found in 1 case of a cohort of 11 AFFs, whereas the second study comprising 10 AFF cases did not find mutations in ALPL. Targeted sequencing of ALPL, COL1A1, COL1A2, and SOX9 genes in 5 cases of AFF identified a variant in COL1A2 in 1 case. These findings suggest a genetic susceptibility for AFFs. A large multicenter collaborative study of well-phenotyped AFF cases and controls is needed to understand the role of genetics in this uncommon condition. PMID- 30283887 TI - Primary Osteoporosis in Young Adults: Genetic Basis and Identification of Novel Variants in Causal Genes. AB - Genetic determinants contribute to osteoporosis and enhance the risk of fracture. Genomewide association studies of unselected population-based individuals or families have identified polymorphisms in several genes related to low bone density, but not in osteoporotic patients with Z-score < -2.0 SD with fragility fracture(s). The aim of this study was to determine the causal genes of idiopathic osteoporosis in the adulthood. Also, we used next-generation sequencing of candidate genes in a cohort of 123 young or middle-aged adults with idiopathic osteoporosis. All patients were included if they had a low bone mineral density (Z-score < -2 SD), a diagnosis before age 55 years (mean +/- SD, 48.4 +/- 10.6 years; mean +/- SD age at first fracture, 30.4 +/- 17.4 years) and fracture or not. We found that 11 patients carried rare or novel variants in COL1A2 (n = 4), PLS3 (n = 2), WNT1 (n = 4), or DKK1 (n = 1). We showed a high prevalence of pathogenic variants in LRP5: 22 patients (17.8%) had the p.Val667Met variant, including three at the homozygous level and 16 (13%) carrying a novel or very rare variant. Functional analysis revealed that the LRP5 missense variants resulted in reduced luciferase activity, which indicates reduced activation of canonical WNT signaling. The clinical phenotype of patients carrying causal gene variants was indistinguishable. In conclusion, molecular screening of young osteoporotic adults revealed several variants and could be useful to characterize susceptibility genes for personalizing treatment, in particular for the new anabolic drugs.(c) 2017 The Authors.

AB - Osteocytes are the most abundant cell type in bone and play a central role in orchestrating skeletal remodeling, in part by producing paracrine-acting factors that in turn influence osteoblast and osteoclast activity. Recent evidence has indicated that osteocytes are crucial cellular targets of parathyroid hormone (PTH). Here, we will review the cellular and molecular mechanisms through which PTH influences osteocyte function. Two well-studied PTH target genes in osteocytes are SOST and receptor activator of NF-kappaB ligand (RANKL). The molecular mechanisms through which PTH regulates expression of these two crucial target genes will be discussed. Beyond SOST and RANKL, PTH/PTH-related peptide (PTHrP) signaling in osteocytes may directly influence the way osteocytes remodel their perilacunar environment to influence bone homeostasis in a cell-autonomous manner. Here, I will highlight novel, additional mechanisms used by PTH and PTHrP to modulate bone homeostasis through effects in osteocytes. (c) 2017 The Authors.

PMID- 30283889 TI - Sclerostin Antibody Treatment Stimulates Bone Formation to Normalize Bone Mass in Male Down Syndrome Mice. AB - Down syndrome (DS), characterized by trisomy of human chromosome 21, is associated with a variety of endocrine disorders as well as profound skeletal abnormalities. The low bone mass phenotype in DS is defined by low bone turnover due to decreased osteoclast and osteoblast activity, decreasing the utility of antiresorptive agents in people with DS. Sclerostin antibody (SclAb) is a therapeutic candidate currently being evaluated as a bone anabolic agent. Scl, the product of the sclerostin gene (SOST), inhibits bone formation through its inhibition of Wnt signaling. SclAb increases bone mass by suppressing the action of the endogenous inhibitor of bone formation, Scl. To examine the effects of SclAb on the DS bone phenotype, 8-week-old male wild-type (WT) andTs65Dn DS mice were treated with 4 weekly iv injections of 100 mg/kg SclAb. Dual-energy X-ray absorptiometry (DXA), microCT, and dynamic histomorphometry analyses revealed that SclAb had a significant anabolic effect on both age-matched WT littermate controls and Ts65Dn DS mice that was osteoblast mediated, without significant changes in osteoclast parameters. SclAb treatment significantly increased both cortical and trabecular bone mass at multiple sites; SclAb treatment resulted in the normalization of Ts65Dn bone mineral density (BMD) to WT levels in the proximal tibia, distal femur, and whole body. Ex vivo bone marrow cultures demonstrated that SclAb increased the recruitment of the mesenchymal progenitors into the osteoblast lineage, as indicated by increased alkaline phosphatase positive colonies, with no effect on osteoclast differentiation. Together, in the setting of a murine model of DS and decreased bone turnover, SclAb had a potent anabolic effect. SclAb stimulated bone formation and increased osteoblastogenesis without affecting osteoclastogenesis or bone resorption. These data suggest that SclAb is a promising new therapy to improve bone mass and reduce fracture risk in the face of the low bone mass and turnover prevalent in the DS population. PMID- 30283890 TI - Flare-Up After Maxillofacial Surgery in a Patient With Fibrodysplasia Ossificans Progressiva: An [18F]-NaF PET/CT Study and a Systematic Review. AB - Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder leading to progressive heterotopic ossifications (HO) of muscles, tendons, and ligaments, which can be induced by trauma or by surgery. Despite strong medical advice to the contrary, an FOP patient insisted on surgery to alleviate her complete trismus, which caused an unbearable impact on her quality of life (QOL). The entire trismus history of this FOP patient is presented. [18F]-NaF position emission tomography/computed tomography (PET/CT) scans were introduced as an imaging method for heterotopic bone formation activity. To place our findings into context, a systematic review on jaw surgery in FOP was performed. After falling down the stairs, a 9-year-old patient developed mobility impairment of her left-sided jaw. During the following 13 years bone scintigraphy showed persistent activity of the disease leading to progressive left-sided zygomatico mandibular fusion by HO, resulting in complete trismus. Within 1 month after HO removal on the left side and a matching right coronoidectomy, [18F]-NaF PET/CT demonstrated a substantial flare-up activity followed by new HO in both masseter and temporalis muscles. Despite recurrent HO and trismus her QOL increased due to a stable increased interincisal opening of 5.5 mm. Although systematic review reveals a 100% risk of HO recurrence after jaw surgery, information on improved QOL is scarce. In conclusion, surgery in FOP may be beneficial for QOL despite new HO formation. Assessment of disease activity using [18F]-NaF PET/CT is possible before HO is evident on CT and may serve as a new and quantitative marker of the disease. (c) 2017 The Authors.

PMID- 30283892 TI - Optimizing Sequential and Combined Anabolic and Antiresorptive Osteoporosis Therapy. AB - As osteoporosis therapy options have expanded, and clinical guidelines have begun to embrace the concept of limited treatment courses and "drug holidays," the choices that physicians must make when initiating, electing to continue, or switching therapies have become more complex. As a result, one of the fundamental issues that must be carefully considered is whether, when, and in what sequence anabolic therapies should be utilized. This review evaluates the current evidence supporting the optimal sequence for the use of anabolic and antiresorptive drugs and assesses the expanding number of clinical trials favoring the initial use of anabolic therapy followed by an antiresorptive agent. This review also explores the evidence suggesting that the effectiveness of anabolic medications are diminished when used in patients that have been previously treated with specific antiresorptive drugs for prolonged periods. Finally, the recent advances in designing combination antiresorptive/anabolic treatment approaches are detailed, with a focus on combined denosumab/teriparatide regimens, which appear to provide the most substantial and clinically relevant skeletal benefits to patients with established osteoporosis.

PMID- 30283893 TI - Cytokine Mixtures Mimicking Secretomes From Mesenchymal Stem Cells Improve Medication-Related Osteonecrosis of the Jaw in a Rat Model. AB - Recently, several studies have demonstrated that intravenous administration of mesenchymal stem cells (MSCs) improve medication-related osteonecrosis of the jaw (MRONJ), and paracrine effects of secretomes from MSCs have been hypothesized as the primary contributors. These secretomes in conditioned media from human MSCs (MSC-CM) were previously demonstrated to promote bone and tissue regeneration. Because MSC-CM contain cytokines monocyte chemoattractant protein (MCP)-1, insulin growth factor (IGF)-1, and vascular endothelial growth factor (VEGF) at relatively higher concentrations than other factors, these cytokines were considered as relevant active factors for tissue regeneration. By mixing the recombinant proteins of MCP-1, IGF-1, and VEGF, included at the same concentrations in MSC-CM, we prepared cytokine mixtures mimicking MSC-CM and then evaluated its therapeutic effects in a rat MRONJ model. In vitro, cytokine mixtures promoted osteogenic differentiation, migration, and proliferation of rat MSCs. In addition, these maintained osteoclastic function. In vivo, we used a rat MRONJ model to examine therapeutic effects of the cytokine mixtures through intravenous administration. In MSC-CM or cytokine mixture group, open alveolar sockets in 66% or 67% of the rats with MRONJ, respectively, healed with complete soft tissue coverage and socket bones, whereas in the other groups, the exposed necrotic bone with inflamed soft tissue remained. Histological analysis revealed new bone formation and the appearance of osteoclasts in MSC-CM or cytokine mixture group; however, osteoclasts were significantly reduced in the other groups. Thus, we concluded that intravenous administration of cytokine mixtures might be an effective therapeutic modality for treating patients with MRONJ. PMID- 30283894 TI - An Ectopic Imaging Window for Intravital Imaging of Engineered Bone Tissue. AB - Tissue engineering is a promising branch of regenerative medicine, but its clinical application remains limited because thorough knowledge of the in vivo repair processes in these engineered implants is limited. Common techniques to study the different phases of bone repair in mice are destructive and thus not optimal to gain insight into the dynamics of this process. Instead, multiphoton intravital microscopy (MP-IVM) allows visualization of (sub)cellular processes at high resolution and frequency over extended periods of time when combined with an imaging window that permits optical access to implants in vivo. In this study, we have developed and validated an ectopic imaging window that can be placed over a tissue-engineered construct implanted in mice. This approach did not interfere with the biological processes of bone regeneration taking place in these implants, as evidenced by histological and micro-computed tomography (MUCT)-based comparison to control ectopic implants. The ectopic imaging window permitted tracking of individual cells over several days in vivo. Furthermore, the use of fluorescent reporters allowed visualization of the onset of angiogenesis and osteogenesis in these constructs. Taken together, this novel imaging window will facilitate further analysis of the spatiotemporal regulation of cellular processes in bone tissue-engineered implants and provides a powerful tool to enhance the therapeutic potential of bone tissue engineering.

PMID- 30283895 TI - Serum Calcium to Phosphorous (Ca/P) Ratio Is a Simple, Inexpensive, and Accurate Tool in the Diagnosis of Primary Hyperparathyroidism. AB - Primary hyperparathyroidism (PHPT) diagnosis is challenging and is based on serum calcium (Ca) and parathyroid hormone (PTH). Because serum Ca and phosphorous (P) are inversely related in PHPT, we investigated the diagnostic value of the serum Ca/P ratio in the diagnosis of PHPT. We report a single-center, case-controlled, retrospective study including 97 patients with documented PHPT and compared them with those of 96 controls (C). The main outcome measures were: serum PTH, 25-OH vitamin D, Ca, P, albumin, and creatinine. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the serum Ca/P ratio were calculated. The results were verified using an independent, anonymous set of data extracted from a laboratory database containing over 900 million entries. A total of 35 (36.1%) PHPT patients had normocalcemic PHPT (NCHPT). Ca and PTH were significantly higher in PHPT than in C (p < 0.0001). P was significantly lower in PHPT than in C (p < 0.0001). The Ca/P ratio was significantly higher in PHPT than in C (p < 0.0001). Receiver-operating characteristic (ROC) curves analyses identified a cutoff of 2.71 (3.5 if Ca and P are expressed in mg/dL) for Ca/P ratio with a sensitivity and specificity of 86% and 87%, respectively (p < 0.0001), confirmed by the independent, big data approach. In conclusion, Ca/P is a valuable tool for the diagnosis of PHPT and is of superior value compared to serum Ca alone, especially in NCPHT. Because Ca/P is simple, inexpensive, and easily accessible worldwide, this ratio is useful for PHPT diagnosis, especially in laboratory/medical settings relying on limited resources, such as low-income countries.

PMID- 30283898 TI - Early Signs of Bone and Cartilage Changes Induced by Treadmill Exercise in Rats. AB - This study aims to investigate the earliest alterations of bone and cartilage tissues as a result of different exercise protocols in the knee joint of Wistar rats. We hypothesize that pretraining to a continuous intense running protocol would protect the animals from cartilage degeneration. Three groups of animals were used: (i) an adaptive (pretraining) running group that ran for 8 weeks with gradually increasing velocity and time of running followed by a constant running program (6 weeks of 1.12 km/hour running per day); (ii) a non-adaptive running (constant running) group that initially rested for 8 weeks followed by 6 weeks of constant running; and (iii) a non-running (control) group. At weeks 8, 14, and 20 bone and cartilage were analyzed. Both running groups developed mild symptoms of cartilage irregularities, such as chondrocyte hypertrophy and cell clustering in different cartilage zones, in particular after the adaptive running protocol. As a result of physical training in the adaptive running exercise a dynamic response of bone was detected at week 8, where bone growth was enhanced. Conversely, the thickness of epiphyseal trabecular and subchondral bone (at week 14) was reduced due to the constant running in the period between 8 and 14 weeks. Finally, the intermediate differences between the two running groups disappeared after both groups had a resting period (from 14 to 20 weeks). The adaptive running group showed an increase in aggrecan gene expression and reduction of MMP2 expression after the initial 8 weeks running. Thus, the running exercise models in this study showed mild bone and cartilage/chondrocyte alterations that can be considered as early-stage osteoarthritis. The pretraining adaptive protocol before constant intense running did not protect from mild cartilage degeneration. (c) 2017 The Authors.

AB - Bariatric surgery results in long-term weight loss and improvement or resolution in obesity-related comorbidities. However, mounting evidence indicates that it adversely affects bone health. This review summarizes clinical research findings about the impact of bariatric surgery on skeletal outcomes. The literature is the largest and strongest for the Roux-en-Y gastric bypass (RYGB) procedure, as RYGB was the most commonly performed bariatric procedure worldwide until it was very recently overtaken by the sleeve gastrectomy (SG). Because SG is a newer procedure, its skeletal effects have not yet been well defined. Epidemiologic studies have now demonstrated an increased risk of fracture after RYGB and biliopancreatic diversion with duodenal switch, both of which include a malabsorptive component. As these epidemiologic data have emerged, patient oriented studies have elucidated the bone tissue-level changes that may account for the heightened skeletal fragility. Bariatric surgery induces early and dramatic increases in biochemical markers of bone turnover. A notable feature of recent patient-oriented clinical studies is the application of advanced skeletal imaging modalities; studies address the limitations of dual-energy X-ray absorptiometry (DXA) by using quantitative computed tomography (QCT)-based modalities to examine volumetric bone mineral density and compartment-specific density and microstructure. RYGB results in pronounced declines in bone mass at the axial skeleton demonstrated by DXA and QCT, as well as at the appendicular skeleton demonstrated by high-resolution peripheral quantitative computed tomography (HR-pQCT). RYGB has detrimental effects on trabecular and cortical microarchitecture and estimated bone strength. Skeletal changes after RYGB appear early and continue even after weight loss plateaus and weight stabilizes. The skeletal effects of bariatric surgery are presumably multifactorial, and mechanisms may involve nutritional factors, mechanical unloading, hormonal factors, and changes in body composition and bone marrow fat. Clinical guidelines address bone health and may mitigate the negative skeletal effects of surgery, although more research is needed to direct and support such guidelines. (c) 2018 The Authors.

PMID- 30283899 TI - Differential Adaptive Response of Growing Bones From Two Female Inbred Mouse Strains to Voluntary Cage-Wheel Running. AB - The phenotypic response of bones differing in morphological, compositional, and mechanical traits to an increase in loading during growth is not well understood. We tested whether bones of two inbred mouse strains that assemble differing sets of traits to achieve mechanical homeostasis at adulthood would show divergent responses to voluntary cage-wheel running. Female A/J and C57BL6/J (B6) 4-week old mice were provided unrestricted access to a standard cage-wheel for 4 weeks. A/J mice have narrow and highly mineralized femora and B6 mice have wide and less mineralized femora. Both strains averaged 2 to 9.5 km of running per day, with the average-distance run between strains not significantly different (p = 0.133). Exercised A/J femora showed an anabolic response to exercise with the diaphyses showing a 2.8% greater total area (Tt.Ar, p = 0.06) and 4.7% greater cortical area (Ct.Ar, p = 0.012) compared to controls. In contrast, exercised B6 femora showed a 6.2% (p < 0.001) decrease in Tt.Ar (p < 0.001) and a 6.7% decrease in Ct.Ar (p = 0.133) compared to controls, with the femora showing significant marrow infilling (p = 0.002). These divergent morphological responses to exercise, which did not depend on the daily distance run, translated to a 7.9% (p = 0.001) higher maximum load (ML) for exercised A/J femora but no change in ML for exercised B6 femora compared to controls. A consistent response was observed for the humeri but not the vertebral bodies. This differential outcome to exercise has not been previously observed in isolated loading or forced treadmill running regimes. Our findings suggest there are critical factors involved in the metabolic response to exercise during growth that require further consideration to understand how genotype, exercise, bone morphology, and whole-bone strength interact during growth.

PMID- 30283900 TI - An N-Ethyl-N-Nitrosourea (ENU) Mutagenized Mouse Model for Autosomal Dominant Nonsyndromic Kyphoscoliosis Due to Vertebral Fusion. AB - Kyphosis and scoliosis are common spinal disorders that occur as part of complex syndromes or as nonsyndromic, idiopathic diseases. Familial and twin studies implicate genetic involvement, although the causative genes for idiopathic kyphoscoliosis remain to be identified. To facilitate these studies, we investigated progeny of mice treated with the chemical mutagen N-ethyl-N nitrosourea (ENU) and assessed them for morphological and radiographic abnormalities. This identified a mouse with kyphoscoliosis due to fused lumbar vertebrae, which was inherited as an autosomal dominant trait; the phenotype was designated as hereditary vertebral fusion (HVF) and the locus as Hvf. Micro computed tomography (MUCT) analysis confirmed the occurrence of nonsyndromic kyphoscoliosis due to fusion of lumbar vertebrae in HVF mice, consistent with a pattern of blocked vertebrae due to failure of segmentation. MUCT scans also showed the lumbar vertebral column of HVF mice to have generalized disc narrowing, displacement with compression of the neural spine, and distorted transverse processes. Histology of lumbar vertebrae revealed HVF mice to have irregularly shaped vertebral bodies and displacement of intervertebral discs and ossification centers. Genetic mapping using a panel of single nucleotide polymorphic (SNP) loci arranged in chromosome sets and DNA samples from 23 HVF (eight males and 15 females) mice, localized Hvf to chromosome 4A3 and within a 5 megabase (Mb) region containing nine protein coding genes, two processed transcripts, three microRNAs, five small nuclear RNAs, three large intergenic noncoding RNAs, and 24 pseudogenes. However, genome sequence analysis in this interval did not identify any abnormalities in the coding exons, or exon-intron boundaries of any of these genes. Thus, our studies have established a mouse model for a monogenic form of nonsyndromic kyphoscoliosis due to fusion of lumbar vertebrae, and further identification of the underlying genetic defect will help elucidate the molecular mechanisms involved in kyphoscoliosis.

PMID- 30283901 TI - The Interaction of BMP2-Induced Defect Healing in Rat and Fixator Stiffness Modulates Matrix Alignment and Contraction. AB - Successful fracture healing requires a tight interplay between mechanical and biological cues. In vitro studies illustrated that mechanical loading modulates bone morphogenetic protein (BMP) signaling. However, in the early phases of large bone defect regeneration in vivo, the underlying mechanisms leading to this mechanosensation remained unknown. We investigated the interaction of BMP2 stimulation and mechanical boundary conditions in a rat critical-sized femoral defect model (5 mm) stabilized with three distinctly different external fixator stiffness. Defects were treated with 5 MUg rhBMP2 loaded on an absorbable collagen sponge. Early matrix alignment was monitored by second-harmonic generation imaging. Bony bridging of defects and successive healing was monitored by histology at day 7 and day 14 as well as in vivo microCT at days 10, 21, and 42 post-operation. Femora harvested at day 42 were characterized mechanically assessing torsional load to failure ex vivo. At tissue level, differences between groups were visible at day 14 with manifest bone formation in the microCT. Histologically, we observed prolonged chondrogenesis upon flexible fixation, whereas osteogenesis started earlier after rigid and semirigid fixation. At later time points, there was a boost of bone tissue formation upon flexible fixation, whereas other groups already displayed signs of tissue maturation. Based on gene expression profiling, we analyzed the mechanobiological interplay. Already at day 3, these analyses revealed differences in expression pattern, specifically of genes involved in extracellular matrix formation. Gene regulation correlating with fixator stiffness was pronounced at day 7 comprising genes related to immunological processes and cellular contraction. The influence of loading on matrix contraction was further investigated and confirmed in a 3D bioreactor. Taken together, we demonstrate an early onset of mechanical conditions influencing BMP2-induced defect healing and shed light on gene regulatory networks associated with extracellular matrix organization and contraction that seemed to directly impact healing outcomes.

AB - Pharmacoepidemiology is used extensively in osteoporosis research and involves the study of the use and effects of drugs in large numbers of people. Randomized controlled trials are considered the gold standard in assessing treatment efficacy and safety. However, their results can have limited external validity when applied to day-to-day patients. Pharmacoepidemiological studies aim to assess the effect/s of treatments in actual practice conditions, but they are limited by the quality, completeness, and inherent bias due to confounding. Sources of information include prospectively collected (primary) as well as readily available routinely collected (secondary) (eg, electronic medical records, administrative/claims databases) data. Although the former enable the collection of ad hoc measurements, the latter provide a unique opportunity for the study of large representative populations and for the assessment of rare events at relatively low cost. Observational cohort and case-control studies, the most commonly implemented study designs in pharmacoepidemiology, each have their strengths and limitations. However, the choice of the study design depends on the research question that needs to be answered. Despite the many advantages of observational studies, they also have limitations. First, missing data is a common issue in routine data, frequently dealt with using multiple imputation. Second, confounding by indication arises because of the lack of randomization; multivariable regression and more specific techniques such as propensity scores (adjustment, matching, stratification, trimming, or weighting) are used to minimize such biases. In addition, immortal time bias (time period during which a subject is artefactually event-free by study design) and time-varying confounding (patient characteristics changing over time) are other types of biases usually accounted for using time-dependent modeling. Finally, residual "uncontrolled" confounding is difficult to assess, and hence to account for it, sensitivity analyses and specific methods (eg, instrumental variables) should be considered.

However, there are only a few treatment options with marginal clinical benefits for this condition. Muscle repair after injury involves multiple and complex processes, such as the inflammation phase, regeneration phase, and remodeling phase. To develop a treatment modality and to examine the efficacy of novel interventions and agents for patients with muscle injuries, it is essential to establish a reliable and sensitive method to monitor the changes in muscle structure and status during muscle repair. Diffusion-weighted magnetic resonance imaging has been widely used to assess the diffusivity of water molecules in tissue. When it is used in combination with diffusion tensor imaging (DTI), the microstructure of muscle tissue can be indirectly depicted. In the present study, we evaluated the time-course changes in the diffusivity and anisotropy in muscles by DTI and histology after injury in mice. We found that the diffusivity and anisotropy exhibit distinct kinetics during muscle repair and that these kinetics were significantly altered in mutant mice with a defect in muscle regeneration. Our data show that muscle repair processes can be readily evaluated and monitored by DTI technique and suggest that DTI can be clinically applied for assessing muscle injury and repair in humans.

PMID- 30283904 TI - Whole-Exome Sequencing Identifies an Intronic Cryptic Splice Site in SERPINF1 Causing Osteogenesis Imperfecta Type VI. AB - The heritable disorder osteogenesis imperfecta (OI) is characterized by bone fragility and low bone mass. OI type VI is an autosomal recessive form of the disorder with moderate to severe bone fragility. OI type VI is caused by mutations in the serpin peptidase inhibitor, clade F, member 1 (SERPINF1), the gene coding for pigment epithelium-derived factor (PEDF). Here, we report a patient with OI type VI caused by a novel homozygous intronic variant in SERPINF1 identified by whole-exome sequencing (WES). The mutation was not identified using a low bone mass gene panel based on next-generation sequencing. This variant creates a novel consensus splice donor site (AGGC to AGGT) in intron 4. Analysis of cDNA generated from fibroblasts revealed retention of a 32-bp intronic fragment between exons 4 and 5 in the cDNA, a result of alternative splicing from the novel splice-donor site. As a result, the aberrant insertion of this intronic fragment generated a frameshift pathogenic variant and induced nonsense-mediated decay. Furthermore, gene expression by quantitative PCR showed SERPINF1 expression was dramatically reduced in patient fibroblasts, and PEDF level was also significantly reduced in the patient's plasma. In conclusion, we report a novel homozygous variant that generates an alternative splice-donor in intron 4 of SERPINF1 which gives rise to severe bone fragility. The work also demonstrates clinical utility of WES analysis, and consideration of noncoding variants, in the diagnostic setting of rare bone diseases. (c) 2018 The Authors.

PMID- 30283905 TI - Sixty-Two-Year-Old Male Suffering From Uremic Leontiasis Ossea Caused by Severe Secondary Hyperparathyroidism. AB - Secondary hyperparathyroidism (SHPT) is a long-term complication of chronic kidney disease-mineral and bone disorder (CKD-MBD). SHPT is characterized by hyperplasia of the parathyroid glands and abnormal secretion of parathyroid hormones (PTH), calcium and phosphorous metabolic disorders, renal osteodystrophy, vascular and soft tissue calcification, malnutrition, and other multiple system complications, which can seriously affect the quality of life of the patient and increase the risk of cardiovascular disease and mortality rate. Uremic leontiasis ossea (ULO) is a medical condition only rarely encountered clinically. SHPT causes craniofacial bone deformity accompanied by lesions of the nerve, cardiovascular, respiratory, bone, or other systems within the body. The case discussed here is related to severe SHPT. A 62-year-old male patient was suffering from leontiasis ossea, pectus excavatum, vascular calcification, spontaneous bone fractures, and lower limb deformities. He was undergoing hemodialysis and given total parathyroidectomy (TPTX) with autotransplantation (AT). We further analyzed the multivariate therapeutic effects of TPTX on this patient in order to provide clinical data for standardized treatment of individuals with CKD-MBD. PMID- 30283907 TI - Molecular Phenotyping of Telomerized Human Bone Marrow Skeletal Stem Cells Reveals a Genetic Program of Enhanced Proliferation and Maintenance of Differentiation Responses. AB - Long-term in vitro expansion of bone marrow stromal (skeletal) stem cells (also known as human mesenchymal stem cells [hMSC]) is associated with replicative senescence and impaired functions. We have previously reported that telomerization of hMSC through hTERT overexpression led to bypassing a replicative senescence phenotype and improved in vitro and in vivo functions. However, the molecular consequence of telomerization is poorly characterized. Thus, we compared the molecular phenotype of a well-studied telomerized hMSC (hMSC-TERT) cell line with primary hMSC. At a cellular level, both cell populations exhibited strong concordance for the known hMSC CD markers, similar responses to osteoblast (OB) differentiation induction, and formed heterotopic bone in vivo. Overall gene expression was highly correlated between both cell types with an average Pearson's correlation coefficient (R2) between the gene expression of all primary hMSC and all hMSC-TERT samples of 0.95 (range 0.93 0.96). Quantitative analysis of gene expression of CD markers, OB cell markers, and transcription factors (TF) showed a high degree of similarity between the two cell populations (72%, 77%, and 81%, respectively). The hMSC-TERT population was enriched mainly for genes associated with cell cycle and cell cycle signaling when compared with primary hMSC. Other enrichment was observed for genes involved in cell adhesion and skeletal system development and immune response pathways. Interestingly, hMSC-TERT shared a telomerization signature with upregulation of cancer/testis antigens, MAGE, and PAGE genes. Our data demonstrate that the enhanced biological characteristics of hMSC after telomerization are mainly due to enhanced expression of cell proliferation genes, whereas gene expression responses to differentiation are maintained.

PMID- 30283906 TI - The Hidden Burden of Fractures in People Living With HIV. AB - The survival of people living with human immunodeficiency virus (HIV) has increased markedly since the advent of antiretroviral therapy (ART). However, other morbidities have emerged, including osteoporosis. The estimated incidence of fractures at any site in people living with HIV ranges from 0.1 per 1000 person-years to 8.4 per 1000 person-years: at least twice that of people without HIV. This increased risk seems to be related to HIV itself and its treatment. Risk factors for bone disease in HIV-positive (HIV+) subjects include both classical risk factors for osteoporosis and fracture and factors linked to HIV itself, such as inflammation, reconstitution syndrome, low CD4, ART, and co infection with hepatitis B and C viruses. The risk of fractures in these individuals can be at least partially assessed by measurement of BMD and the Fracture Risk Assessment Tool (FRAXTM). Only alendronate and zoledronic acid have been studied in HIV+ individuals; both show beneficial effects on BMD, although data on fracture reduction are not available. (c) 2018 The Authors.

PMID- 30283908 TI - How Is Adolescent Bone Mass and Density Influenced by Early Life Body Size and Growth? The Tromso Study: Fit Futures-A Longitudinal Cohort Study From Norway. AB - The effect of birth weight and childhood body mass index (BMI) on adolescents' bone parameters is not established. The aim of this longitudinal, population based study was to investigate the association of birth weight, childhood BMI, and growth, with adolescent bone mass and bone density in a sample of 633 adolescents (48% girls) from The Tromso Study: Fit Futures. This population-based cohort study was conducted in 2010-2011 and 2012-2013 in Tromso, Norway. Bone mineral content (BMC) and areal BMD (aBMD) were measured at total hip (TH) and total body (TB) by dual-energy X-ray absorptiometry (DXA) and converted to internal Z-scores. Birth weight and childhood anthropometric measurements were retrospectively obtained from the Medical Birth Registry of Norway and childhood health records. Associations between birth weight, BMI, and growth were evaluated by fitting linear mixed models with repeated measures of BMC and aBMD at ages 15 to 17 and 18 to 20 years as the outcome. In crude analysis, a significant positive association (p < 0.05) with TB BMC was observed per 1 SD score increase in birth weight, observed in both sexes. Higher rate of length growth, conditioned on earlier size, from birth to age 2.5 years, and higher rate of weight gain from ages 6.0 to 16.5 years, conditioned on earlier size and concurrent height growth, revealed stronger associations with bone accrual at ages 15 to 20 years compared with other ages. Compared with being normal weight, overweight/obesity at age 16.5 years was associated with higher aBMD Z-scores: beta coefficient (95% confidence interval [CI]) of 0.78 (0.53, 1.03) and 1.08 (0.85, 1.31) in girls, 0.63 (0.42, 0.85) and 0.74 (0.54, 0.95) in boys at TH and TB, respectively. Similar associations were found for BMC. Being underweight was consistently negatively associated with bone parameters in adolescence. In conclusion, birth weight influences adolescent bone mass but less than later growth and BMI in childhood and adolescence. (c) 2018 The Authors.

PMID- 30283909 TI - Compromised Activation of Vitamin D After Elective Surgery: A Prospective Pilot Study. AB - Surgical stress reduces concentrations of most proteins in serum and necessitates a rapid adjustment of hormones dependent on protein binding. Activation of vitamin D by renal 1alpha-hydroxylation is dependent on protein binding because 1,25-dihydroxyvitamin D (1,25(OH)2D3) is formed after megalin-mediated reabsorption of 25-hydroxyvitamin D (25OHD) bound to vitamin D binding protein (DBP). Postoperative alterations in serum concentrations of DBP and albumin may therefore impair 1,25(OH)2D3 production. Our objective was to determine sex specific changes in serum concentrations of vitamin D metabolites and sex steroids 2, 6, 24, and 48 hours and 3 weeks postoperatively. Fourteen women and eleven men aged 45 to 77 years without severe comorbidities undergoing unilateral total knee arthroplasty participated in this prospective study in a tertiary center for arthroplasty (trial ID: NCT02336932). The main outcome measures were total and free serum concentrations of 25OHD, 1,25(OH)2D3, 24,25-dihydroxyvitamin D, DBP, albumin, sex hormone binding globulin (SHBG), calcium, and parathyroid hormone (PTH). Serum albumin and SHBG decreased postoperatively (Deltaalbumin48h 18% [-22%; -14%]). Unexpectedly, concentrations of DBP and 25OHD remained unaltered, but 1,25(OH)2D3 declined postoperatively. 1,25(OH)2D3 was 3 weeks after surgery -24% (-40%; -8%) lower than preoperative levels, whereas 24,25 dihydroxyvitamin-D remained unchanged in postmenopausal women. The calculated conversion rate of 25OHD to 1,25(OH)2D3 was strongly associated with serum 25-OHD and PTH preoperatively, whereas serum calcium was most predictive postoperatively. In conclusion, surgery had no effect on serum concentrations of DBP, 25OHD, and PTH, whereas production of 1,25(OH)2D3 was markedly reduced. Further studies are needed to determine duration and putative outcome effects of this postoperative 1,25(OH)2D3 deficit in women, which in part may be due to discordance in CYP27B1 and CYP24A1 activity. PMID- 30283910 TI - Efficacy of Switching From Teriparatide to Bisphosphonate or Denosumab: A Prospective, Randomized, Open-Label Trial. AB - There is no consensus on an optimal treatment after daily teriparatide (TPTD). We performed a prospective, randomized, open-label, 12-month trial to investigate the efficacy of follow-up treatment after daily TPTD treatment for Japanese patients. Three-hundred patients were enrolled in this study. Patients received oral bisphosphonate (BP) including alendronate (ALN; 35 mg/week) and minodoronate (MINO; 50 mg/month), or subcutaneous denosumab (60 mg/6 month). The primary efficacy measure was bone mineral density (BMD) responses in the lumbar spine (LS) and femoral neck (FN). Lumbar spine BMD increased by 1.3 +/- 5.1% in the ALN subgroups, 0.5 +/- 4.6% in the MINO subgroups, and 4.3 +/- 3.5% in the denosumab subgroups. Femoral neck BMD increased by 0.7 +/- 4.6% in the ALN subgroups, 0.2 +/- 4.6% in the MINO subgroups, and 1.4 +/- 3.4% in the denosumab subgroups. Lumbar spine BMD increases were significantly greater in the denosumab subgroup than the BP subgroups. There were no significant differences in FN BMD increases among the three subgroups. Lumbar spine BMD increases were significantly greater in the denosumab subgroup than the BP subgroups, whereas FN BMD increases were not significant. Denosumab treatment was more effective in increasing BMD and therefore has the potential benefit of fracture prevention. Further research is warranted to determine the optimal treatment after daily TPTD. (c) 2018 The Authors.

PMID- 30283911 TI - Homocysteine-Lowering Treatment and the Risk of Fracture: Secondary Analysis of a Randomized Controlled Trial and an Updated Meta-Analysis. AB - High plasma homocysteine is a risk factor for osteoporotic fractures. Several studies have assessed the possible preventive effect of homocysteine-lowering B vitamin treatment on the risk of fracture with inconclusive results. In the current study, we include new results from the Aspirin Folate Polyp Prevention Study (AFPPS) together with an updated meta-analysis of randomized controlled trials (RCTs). Our objective was to determine whether there is an association between homocysteine-lowering B-vitamin treatment and the risk of fracture. The AFPPS trial was performed between 1994 and 2004 in nine clinical centers in the United States, and 1021 participants were randomized to a daily folic acid dose of 1 mg (n = 516) or placebo (n = 505). The main outcome was fracture of any type. In addition, we analyzed the risk of hip fracture. In the meta-analysis, studies were identified following a search strategy in electronic database and by hand searching. Risk ratio with 95% confidence interval (CI) was chosen for pooled analyses. In the AFPPS, no statistically significant association was found between folic acid treatment and fractures of any type (risk ratio [RR] = 0.95; 95% CI 0.61-1.48) or hip fracture (RR = 0.98; 95% CI 0.25-3.89). In the meta analysis, six RCTs were included with a total of 36,527 participants. For interventions including folic acid and/or vitamin B12, the pooled RR for treatment was 0.97 (95% CI 0.87-1.09) for fractures of any type (n = 1199) and 1.00 (95% CI 0.81-1.23) for hip fractures (n = 335). In conclusion, no association was found between homocysteine-lowering treatment with B vitamins (folic acid and vitamin B12) and the risk of fracture. (c) 2018 The Authors.

PMID- 30283912 TI - Fracture Healing in Two Adult Patients With Hypophosphatasia After Asfotase Alfa Therapy. AB - Infants and children with hypophosphatasia (HPP) treated with asfotase alfa show improvement in bone mineralization and motor function, but it is unclear whether the medication can affect fracture healing in adult HPP patients. We present the course of fracture healing in two adults with HPP on enzyme replacement. Case 1 is a 41-year-old female with infantile-onset HPP who was wheelchair-bound due to a nonhealing tibial fragility fracture sustained 3 years before and also had nonhealing femoral pseudofracture sustained 17 years before starting asfotase alfa therapy in December 2015. One month after medication initiation, she underwent elective osteotomy of tibia and fibula with intramedullary nail fixation. After 3 months of enzyme replacement, she was full weight-bearing and radiographs demonstrated callus formation at osteotomy sites, and at 11 months of therapy, radiographs showed union of the osteotomies. By 11 months of asfotase alfa therapy, there was near resolution of the femoral pseudofracture without interval surgery at this site. Case 2 is a 61-year-old male who showed nonunion of a fragility fracture of the right femur 8 years prior, intramedullary nail fixation 6 years prior, and stress fracture of the left femoral diaphysis sustained 1 year before starting asfotase alfa in October 2015. A trial of teriparatide was unsuccessful in healing of these fractures. On asfotase alfa, radiographs revealed interval healing of the left femur fracture after 12 months and complete healing of the right femur fracture and near resolution of the left femur fracture after 16 months of medical therapy. These two adult patients with HPP showed significant clinical and radiographic improvements in a total of four recalcitrant fractures on enzyme replacement therapy with asfotase alfa.

PMID- 30283913 TI - Reported Consumption of Low-Calorie Sweetener in Foods, Beverages, and Food and Beverage Additions by US Adults: NHANES 2007-2012. AB - Background: Low-calorie sweeteners (LCSs), artificial sweeteners, or high intensity sweeteners are incorporated into foods, beverages, and food and beverage additions (FBAs). Many prior studies have focused on LCS beverage consumption, but not included LCS consumption from foods or FBAs. Objectives: We aimed to describe the prevalence of LCS consumption by US adults, and to examine the relation between intake of products containing LCSs and macronutrients. Methods: Two nonconsecutive 24-h dietary recalls from NHANES 2007-2012 and the National Cancer Institute usual intake method were used to estimate prevalence of LCS intake from foods, beverages, and FBAs, and macronutrients among US adults aged >=19 y (n = 14,098, weighted n = 218,391,752) in a cross-sectional study. The prevalence of LCS consumption from reported foods, beverages, and FBAs among US adults was examined by sociodemographic characteristics and body mass index (BMI). Logistic regression estimated ORs and 95% CIs for associations between sociodemographic characteristics and LCS use (overall and in foods, beverages, and FBAs). Results: Among adults, 47.8% reported intake of >=1 food, beverage, or FBA containing LCSs over 2 d. Intake was higher among: women non-Hispanic whites, college graduates or higher, and those with higher income and obese BMIs (P < 0.001). Intake of beverages containing LCSs was higher for ages 51-70 y than 19 30 y and those with overweight and obese BMIs (P < 0.001) than for normal-weight individuals. Calories, carbohydrate, and sugar intake were lower and fiber was higher in LCS-consumers than in nonconsumers. Specifically, calories from beverages were lower in those who reported LCS intake. Conclusions: Individuals reporting LCS consumption demonstrated lower total energy intake than did individuals without LCS intake. Although the main source of LCSs in the US adult diet was beverages (31.9%), we found that FBAs also present a significant contribution (25.2%), surpassing food (9.3%). This enables targeted understanding of national consumption of these products as well as dietary education and intervention opportunities. PMID- 30283914 TI - An Academia-Industry Partnership for Planning and Executing a Community-Based Feeding Study. AB - A research team from Boston Children's Hospital and Harvard Medical School conducted a community-based feeding study in collaboration with Framingham State University (FSU) and Sodexo, the food service contractor at FSU. The study was a randomized controlled trial, implemented on the FSU campus. For the final year of the study, a satellite feeding site was established at Assabet Valley Regional Technical High School. The purpose of the study was to assess the biological effects of different macronutrient diets. An academia-industry partnership was developed to overcome common challenges associated with hospital-based feeding studies. Benefits included the following: a study site outside of Boston (reducing inconvenience for participants), access to a large commercial kitchen and study-specific kiosk (promoting efficiency), collaboration with Sodexo chefs (ensuring palatability of meals), and opportunity to procure food from contracted vendors. The research (academia) and food service (industry) teams worked together to design, plan, and execute intervention protocols using an integrated approach. During execution, the research team was primarily responsible for overseeing treatment fidelity, whereas the food service team provided culinary expertise, with a strong focus on hospitality and food quality. The study was conducted in 3 cohorts between August 2014 and May 2017. Participants received all of their food for ~30 wk, totaling >160,000 meals. For all 3 cohorts combined, 234 participants provided informed consent, 229 started a standard run in weight-loss diet, 164 lost a mean +/- SD 12% +/- 2% of baseline body weight and were randomly assigned to different macronutrient diets for weight-loss maintenance, and 148 completed the study. During the final and largest cohort, as many as 114 participants received daily meals concurrently. The daily cost per participant for preparation and service of weighed meals and snacks was ~$65. This academia-industry partnership provides a model for controlled feeding protocols in nutrition research, potentially with enhanced cost-effectiveness, practicality, and generalizability. This trial was registered at http://www.clinicaltrials.gov as NCT02068885. PMID- 30283916 TI - Dietary Consumption of Lutein and Zeaxanthin in Panama: A Cross-Sectional Study. AB - Background: The macular pigments of the eye increase with a diet rich in lutein and zeaxanthin, both of which are phytochemicals and important for visual health. Objective: We aimed to determine the dietary consumption of lutein and zeaxanthin in adults working at the Universidad de Panama (University of Panama), Panama City. Method: This was a cross-sectional study with 164 subjects including both men and women >18 y of age and employed at the University of Panama, Panama City, Panama. The data collection was carried out between May and September 2017. A semiquantitative food frequency questionnaire was applied with 43 foods high in lutein and zeaxanthin, which included eggs as the only source of animal protein, 23 vegetables, 15 fruits, and 4 foods prepared with corn as an ingredient. Results: The mean +/- SD age was 45.7 +/- 12.7 y (72% women). The mean +/- SD and median (IQR) lutein consumption were 2.063 +/- 2.334 mg/d and 1.512 (1.385) mg/d, respectively; and for zeaxanthin these were 0.858 +/- 0.866 mg/d and 0.550 (0.819) mg/d, respectively. The food products that contributed the most dietary lutein and zeaxanthin were tomatoes, corn tortilla, and egg yolk. Conclusion: The consumption of lutein and zeaxanthin is low among people working at the University of Panama, and this is not associated with sociodemographic variables. PMID- 30283915 TI - A Structural Equation Modelling Approach to Understanding Influences of Maternal and Family Characteristics on Feeding Practices in Young Children. AB - Background: The family environment is influential for a child's healthy development through parent and sibling influences on feeding practices. Multiple child households may protect against unhealthy feeding practices, but additional children contribute to higher maternal stress. Households of married parents may decrease maternal stress by sharing parental demands. Objective: We aimed to evaluate the collective influence of maternal stress, marital status, and number of children on feeding practices. Methods: Mothers of 2- to 5-y-old children (n = 278) were recruited mainly on a university campus and completed an online survey to examine associations between maternal stress (Depression, Anxiety, Stress Scale), number of children, marital status, and feeding practices (restriction and pressure to eat; Child Feeding Questionnaire). Relationships were examined through the use of multivariate regression and structural equation modelling. Results: A mainly married (85%) and Caucasian (73%) sample participated, with most mothers reporting multiple children [2 children (45%) or >=3 children (24%)]. Marital status was not associated with either feeding practice, i.e., restriction and pressure to eat (P < 0.05). In adjusted models, maternal stress (beta = 0.04, SE = 0.01, P = 0.003) and number of children (beta = 0.24, SE = 0.08, P = 0.003) in the household individually contributed to higher feeding restriction; their interaction resulted in lower feeding restriction (beta = 0.01, SE = 0.05, P = 0.005). In stratified models, maternal stress was associated with restriction in single-child households (beta = -0.03, SE = 0.009, P = 0.002), but not multiple-child households (beta = -0.004, SE = 0.005, P = 0.40). Conclusions: Number of children had no effect on feeding practices individually, but may contribute to a less restrictive feeding environment. Additional investigation into creating less stressful and more positive feeding environments for all mothers can lead to healthier mothers and families. PMID- 30283917 TI - Effective mental health interventions to reduce hospital readmission rates: a systematic review. AB - Background: Hospitals in the United States are financially penalized for having a higher than expected thirty-day readmission ratio among patients initially hospitalized for heart failure, acute myocardial infarction (AMI), pneumonia, chronic obstructive pulmonary disease (COPD), coronary artery bypass graft (CABG) surgery, or hip and knee replacement. Patients hospitalized for these conditions that have comorbid mental health diagnoses or symptoms are at high risk for readmission. Methods: We conducted a systematic review to determine if interventions, that are specifically designed to assess or treat mental health symptoms, can effectively reduce risk of readmission following hospitalization for physical health conditions. We searched on PubMed and Google Scholar for peer reviewed articles published between January 2010 and June 2018 that examined the impact of mental-health interventions on readmissions for physical conditions. Results: After screening 81 full text articles, we found eleven intervention studies, one meta-analysis, and one cross-sectional study that met our inclusion criteria. Only three of the intervention studies found significant differences in readmission rates between intervention and comparison groups. Each of these interventions targeted patients after discharge from the hospital. One of the interventions was a physical health telemonitoring and individual psychotherapy intervention for patients that were initially admitted for heart failure. The second intervention was individual and group psychotherapy sessions for patients who were initially admitted for AMI. The third intervention was a nurse-driven depression care management protocol for home care patients with depressive symptoms who were initially admitted for any physical health condition. The cross sectional study showed that communities with a stronger, social-based public mental health infrastructure had significantly lower physical health readmission rates. Conclusions: The literature identified in this review, appears to provide support for the use of mental health interventions after discharge as a mechanism for reducing physical health condition readmissions. Future research is needed to determine if these interventions can specifically reduce thirty-day readmissions for the six conditions linked to financial penalties. PMID- 30283919 TI - Probing charge transfer characteristics in a donor-acceptor metal-organic framework by Raman spectroelectrochemistry and pressure-dependence studies. AB - The stimuli responsive behaviour of charge transfer donor-acceptor metal-organic frameworks (MOFs) remains an understudied phenomenon which may have applications in tuneable electronic materials. We now report the modification of donor acceptor charge transfer characteristics in a semiconducting tetrathiafulvalene naphthalene diimide-based MOF under applied electrochemical bias and pressure. We employ a facile solid state in situ Raman spectroelectrochemical technique, applied for the first time in the characterisation of electroactive MOFs, to monitor the formation of a new complex TTFTC+-DPNI from a largely neutral system, upon electrochemical oxidation of the framework. In situ pressure-dependent Raman spectroscopy and powder X-ray diffraction experiments performed in a diamond anvil cell revealed blue shifts in the donor and acceptor vibrational modes in addition to contractions in the unit cell which are indicative of bond shortening. This study demonstrates the utility of in situ Raman spectroscopic techniques in the characterisation of redox-active MOFs and the elucidation of their electronic behaviours. PMID- 30283920 TI - Aggregation of P3HT as a preferred pathway for its chemical doping with F4-TCNQ. AB - The chemical doping reaction of P3HT with F4-TCNQ was studied by optical absorption spectroscopy, atomic force microscopy, and Kelvin probe force microscopy. We demonstrate that P3HT aggregation preferentially occurs before the actual charge transfer step takes place, emphasizing the impact of morphology on the chemical doping reaction of conjugated polymers at the molecular level. PMID- 30283918 TI - Utilising dog-computer interactions to provide mental stimulation in dogs especially during ageing. AB - Aged dogs suffer from reduced mobility and activity levels, which can affect their daily lives. It is quite typical for owners of older dogs to reduce all activities such as walking, playing and training, since their dog may appear to no longer need them. Previous studies have shown that ageing can be slowed by mental and physical stimulation, and thus stopping these activities might actually lead to faster ageing in dogs, which can result in a reduction in the quality of life of the animal, and may even decrease the strength of the dog owner bond. In this paper, we describe in detail a touchscreen apparatus, software and training method that we have used to facilitate dog computer interaction (DCI). We propose that DCI has the potential to improve the welfare of older dogs in particular through cognitive enrichment. We provide hypotheses for future studies to examine the possible effects of touchscreen use on physiological, behavioural and cognitive measures of dogs' positive affect and well-being, and any impact on the dog-owner bond. In the future, collaborations between researchers in animal-computer interaction, dog trainers, and cognitive scientists are essential to develop the hardware and software necessary to realise the full potential of this training and enrichment tool. PMID- 30283921 TI - Nonmonotonic thickness-dependence of in-plane thermal conductivity of few-layered MoS2: 2.4 to 37.8 nm. AB - Recent first-principles modeling reported a decrease of in-plane thermal conductivity (k) with increased thickness for few layered MoS2, which results from the change in phonon dispersion and missing symmetry in the anharmonic atomic force constant. For other 2D materials, it has been well documented that a higher thickness could cause a higher in-plane k due to a lower density of surface disorder. However, the effect of thickness on the k of MoS2 has not been systematically uncovered by experiments. In addition, from either experimental or theoretical approaches, the in-plane k value of tens-of-nm-thick MoS2 is still missing, which makes the physics on the thickness-dependent k remain ambiguous. In this work, we measure the k of few-layered (FL) MoS2 with thickness spanning a large range: 2.4 nm to 37.8 nm. A novel five energy transport state-resolved Raman (ET-Raman) method is developed for the measurement. For the first time, the critical effects of hot carrier diffusion, electron-hole recombination, and energy coupling with phonons are taken into consideration when determining the k of FL MoS2. By eliminating the use of laser energy absorption data and Raman temperature calibration, unprecedented data confidence is achieved. A nonmonotonic thickness-dependent k trend is discovered. k decreases from 60.3 W m 1 K-1 (2.4 nm thick) to 31.0 W m-1 K-1 (9.2 nm thick), and then increases to 76.2 W m-1 K-1 (37.8 nm thick), which is close to the reported k of bulk MoS2. This nonmonotonic behavior is analyzed in detail and attributed to the change of phonon dispersion for very thin MoS2 and a reduced surface scattering effect for thicker samples.

AB - In this work, a simple and novel ratiometric fluorescence method based on ROX-DNA functionalized CdZnTeS quantum dots (QDs) was developed for the detection of dopamine (DA) and tyrosinase (TYR). A ratiometric fluorescent probe was constructed by binding phosphorothioate DNA to the metal ions of QDs, which is a modification-free and low-cost method. DA was easily oxidized to DA quinone under the catalysis of TYR by dissolved O2, which effectively quenched the fluorescence of the QDs. Strong linear correlations were achieved for TYR in the range of 10.0 100.0 ng mL-1 and for DA in the range of 10.0-1000.0 nM. The limit of detection was estimated to be as low as 1.05 ng mL-1 for TYR and 1.93 nM for DA. Moreover, various colors were displayed in the course of detection, which could be observed by the naked eye. Therefore, an on-site and sensitive fluorescence method for the visual detection of DA and TYR can be developed. In addition, the findings revealed the potential applicability of the ratiometric fluorescent probe for the detection of DA and TYR in human serum. This ratiometric fluorescence method is not only sensitive and selective but also rapid and convenient for the detection of the analytes without sophisticated instrumentation.

We here report the first example of radical arylations using aromatic nitriles without the assistance of photoirradiation. Importantly, with this method, the direct arylation of C(sp3)-H in benzyl amines provided a practical method for the synthesis of diarylmethylamines without the use of precious transition metal catalysts. PMID- 30283924 TI - Fabrication and simulation of V-shaped Ag nanorods as high-performance SERS substrates. AB - Bending straight Ag nanorods (AgNRs) into V-shaped structures can generate a higher surface-enhanced Raman scattering (SERS) performance. Numerical simulations showed that V-shaped AgNRs with a total length between 300 nm and 800 nm were more sensitive than equal-length straight AgNRs under a 785 nm laser in most cases. It was found that at a laser wavelength between 500 nm and 1000 nm, the Raman enhancement factor (EF) of a V-shaped AgNR's 3rd plasmon mode was not only optimal among the other major plasmon modes, but also outperformed the plasmon modes of straight AgNRs. Besides, a linear relationship between the resonance wavelength of the V-shaped AgNR's 3rd mode and its length was observed both numerically and experimentally, which was beneficial for the optimization of SERS substrates. Under 785 nm laser excitation, V-shaped AgNR substrates with a single arm length between 330 nm and 340 nm possessed the highest SERS efficiency. This work took AgNR array substrates one step closer to practical applications. PMID- 30283925 TI - The promising indicators of the thermal and mechanical properties of collagen from bass and tilapia: synergistic effects of hydroxyproline and cysteine. AB - Collagen has been widely documented as one of the most promising and competitive biomaterials for tissue engineering and medical applications. However, the properties of collagen differ from one source to another. In the present study, type I collagen (COL-I) was extracted and purified from the skins of Japanese sea bass (Lateolabrax japonicus) and Nile tilapia (Oreochromis niloticus). Ultraviolet (UV) spectroscopy, Fourier transform infrared spectroscopy (FTIR) and SDS-PAGE were performed to characterize both COL-Is. The denaturing temperature of bass collagen (BC) was observed to be 27.2 degrees C, and 35.3 degrees C for tilapia collagen (TC). The content of hydroxyproline was 13.4% in TC, which was similar to that in porcine collagen (PC, 13.6%) and higher than that in BC (10.3%), while the content of cysteine in TC (0.87%) was significantly higher than that in PC (0.04%) and BC (0.35%). After incubation at different temperatures for 9 h, more degraded collagen bands appeared in the BC hydrogel (BCH) group than in the TC hydrogel (TCH) group, indicating that TCH exhibited better thermal stability than BCH. The thermal stabilities of TCH and PC hydrogel (PCH) were similar. The compressive stress of TCH was up to 0.099 MPa, while it was 0.047 MPa for BCH and 0.003 MPa for PCH. These results demonstrated that the content of amino acids (especially hydroxyproline and cysteine) has a synergistic effect on the thermal and mechanical properties of BCH, TCH and PCH, which would be an indicator of the thermal and mechanical properties of collagen hydrogels in future studies.

AB - miRNAs are novel diagnostic and prognostic biomarkers for a diversity of diseases like cancers. In this study, an ultrasensitive electrochemical biosensor for miRNA evaluation is fabricated. A methylene blue (MB) labeled DNA probe is firstly modified on a gold electrode. By employing target induced strand displacement amplification and subsequent DNAzyme cleavage cycles, a large number of MB molecules are released. The decreased oxidation peak current could be used to reveal the miRNA concentration. Based on the two efficient signal amplifications, this method shows ultrahigh sensitivity. Its feasibility for the analysis of miRNA in cell lysates is also demonstrated. Therefore, the method shows attractive potential for promising applications in early diagnosis of certain diseases.

AB - Spectroscopic evidence for the structural evolution of Gen- (3 <= n <= 20) clusters is provided by means of simulated anion photoelectron spectra (PES). Both adiabatic detachment energies and HOMO-LUMO gaps of the selected low-lying candidates match well with those measured in experiment. This work demonstrates that PES is a highly sensitive technique for probing both electronic and geometric structures of atomic clusters, whose structural evolution is an elemental signature with characteristic features. PMID- 30283928 TI - Halogen bond shortens and strengthens the bridge bond of [1.1.1]propellane and the open form of [2.2.2]propellane. AB - Detailed electronic structural analysis of [1.1.1]propellane and the open form of [2.2.2]propellane, especially their highest occupied molecular orbital (HOMO), shows the existence of significant electronic congestion at their bridge bond. The HOMO of [1.1.1]propellane is a spread-out orbital of its inverted tetrahedral bridgehead atoms. The HOMO of the open form of [2.2.2]propellane is an anti bonding combination of its bridgehead atoms due to the stabilizing through-bond interaction. This unique spatial disposition of the HOMO enables a high electron density at the bridgehead atoms. Herein, we utilize the electron scavenging power of halogen bond donors to extract a fraction of destabilizing electrons from the bridge bond with the aim to alleviate its electronic congestion, which results in shortening and strengthening of the bridge bond with a reduction in the bond order. This result answers the seminal question raised by K. B. Wiberg in 1983, "how can one have a relatively 'strong bond' without much bonding character?" PMID- 30283930 TI - Local elasticity in nonlinear rheology of interacting colloidal glasses revealed by neutron scattering and rheometry. AB - The flow of colloidal suspensions is ubiquitous in nature and industry. Colloidal suspensions exhibit a wide range of rheological behavior, which should be closely related to the microscopic structure of the systems. With in situ small-angle neutron scattering complemented by rheological measurements, we investigated the deformation behavior of a charge-stabilized colloidal glass at particle level undergoing steady shear. A short-lived, localized elastic response at particle level, termed as the transient elasticity zone (TEZ), was identified from the neutron spectra. The existence of the TEZ, which could be promoted by the electrostatic interparticle potential, is a signature of deformation heterogeneity: the body of fluids under shear behaves like an elastic solid within the spatial range of the TEZ but like fluid outside the TEZ. The size of the TEZ shrinks as the shear rate increases in the shear thinning region, which shows that the shear thinning is accompanied by a diminishing deformation heterogeneity. More interestingly, the TEZ is found to be the structural unit that provides the resistance to the imposed shear, as evidenced by the quantitative agreement between the local elastic stress sustained by the TEZ and the macroscopic stress from rheological measurements at low and moderate shear rates. Our findings provide an understanding on the nonlinear rheology of interacting colloidal glasses from a micro-mechanical view. PMID- 30283931 TI - Tunable band gap of graphyne-based homo- and hetero-structures by stacking sequences, strain and electric field. AB - A comprehensive investigation was carried out on graphyne/graphyne (Gyne/Gyne), graphyne-like BN/graphyne-like BN (BNyne/BNyne) and graphyne/graphyne-like BN (Gyne/BNyne) bilayer structures using van der Waals (vdW)-corrected density functional theory. These bilayers exhibited distinct stacking-dependent characteristics in their ground state electronic structure and also had different responses to external strain and a vertical electric field. For the Gyne/Gyne and Gyne/BNyne bilayers, the application of biaxial tensile strain led to an increase in the band gap, while the application of biaxial compressive strain in addition to uniaxial strain, either under tension or compression, induced a reduction in the band gap. However, in the case of the BNyne/BNyne bilayer, the application of biaxial tensile strain led to a decrease in the band gap, but an increase in the band gap occurred under biaxial compressive strain, which could be explained by a change in the ionic nature of the B-N bonds. Under a vertical electric field, the band gaps of the homo-bilayers (Gyne/Gyne and BNyne/BNyne) decreased and were symmetrical. However, the hetero-bilayer (Gyne/BNyne) exhibited a decreased band gap under a positive electric field, but an almost constant band gap under a negative electric field. The physical origin of the band gap variation under an electric field was unraveled using energy-band theory. Our findings pave the way for experimental research and provide valuable insight into two-dimensional vdW layered structures for use in next generation flexible nanoelectronics and optoelectronic devices. PMID- 30283932 TI - Computational strategies to probe CH activation in dioxo-dicopper complexes. AB - We employ density functional theory and energy decomposition analysis to probe the mechanism of CH activation in dioxo-dicopper complexes. The electrophilicity of monodentate N-donor ligands coordinated to Cu is systematically varied to examine the response of barriers to the two proposed pathways - one-step oxo insertion and two-step radical recombination. Electron-withdrawing ligand stabilize the oxo-insertion transition state via charge transfer interactions, and therefore lead to lower barriers. On the other hand, barriers to the CH activation step in the radical recombination mechanism exhibit almost no dependence on N-donor electrophilicity. Based on the similarities between calculated and experimental Hammett relationships, the oxo-insertion pathway appears to be the preferred mechanism of CH activation in dioxo-dicopper catalysts. PMID- 30283933 TI - High-resolution vibration-rotational spectra and rotational perturbation of the OO-stretching (nu6) band of CH2OO between 879.5 and 932.0 cm-1. AB - We report the observation of a rotationally resolved nu6 band associated with the OO-stretching mode of the simplest Criegee intermediate, CH2OO, in the range of 879.5-932.0 cm-1 (11.37-10.73 MUm) at an optical resolution of 0.0015 cm-1. The spectra were recorded with a tunable cw external-cavity quantum-cascade laser (EC QCL) system coupled with a Herriott multipass absorption cell. Over one thousand lines were assigned to determine the rovibrational parameters of the nu6 band. Rotational parameters A', B', and C' and higher-order parameters DeltaJ, DeltaJK, DeltaK, deltaJ, and deltaK were determined precisely. Rotational perturbations for Ka' = 3, Ka' = 6, and Ka' >= 11 on high-J levels were observed. In particular, for Ka' = 6, frequency shifts as a function of J' showed an avoided crossing; the shifts were analyzed in terms of a Coriolis interaction between modes nu6 and nu8 of CH2OO. According to the distinct temporal profiles, lines of a hot band near 899.5 cm-1 were also identified.

AB - This perspective showcases our development of benzylic and allylic amine and alcohol derivatives as electrophiles for stereospecific, nickel-catalyzed cross coupling reactions, as well as the prior art that inspired our efforts. The success of our effort has relied on the use of benzyl ammonium triflates as electrophiles for cross-couplings via C-N bond activation and benzylic and allylic carboxylates for cross-couplings via C-O bond activation. Our work, along with others' exciting discoveries, has demonstrated the potential of stereospecific, nickel-catalyzed cross-couplings of alkyl electrophiles in asymmetric synthesis, and enables efficient generation of both tertiary and quaternary stereocenters.

PMID- 30283935 TI - Neutral and anionic phosphate-diesters as molecular templates for the encapsulation of a water dimer. AB - The study of water clusters in a confined state has received considerable attention. The simplest among such assemblies of water molecules is the water dimer. Stabilizing this unit at ambient conditions in an appropriate host template, however, has remained a challenge. Herein, we report 2,6 (diphenylmethyl)-4-iso-propyl-phenyl substituted phosphate diesters (both in their neutral and anionic forms) as molecular templates for hosting the water dimer. The robustness of the water dimer within the neutral phosphate-diester ensemble is remarkable. Even when treated with triethylamine the water dimer is not disrupted, while exclusively the P(O)(OH) unit is deprotonated. PMID- 30283936 TI - Factors affecting cyclic durability of all-solid-state lithium batteries using poly(ethylene oxide)-based polymer electrolytes and recommendations to achieve improved performance. AB - A detailed experimental analysis of the factors affecting cyclic durability of all-solid-state lithium batteries using poly(ethylene oxide)-based polymer electrolytes was published in EES by Nakayama et al. We use quantum mechanics to interpret these results, identifying processes involved in the degradation of rechargeable lithium batteries based on polyethylene oxide (PEO) polymer electrolyte with LiTFSI. We consider that ionization of the electrolyte near the cathode at the end of the recharge step is probably responsible for this degradation. We find that an electron is likely removed from PEO next to a TFSI anion, triggering a sequence of steps leading to neutralization of a TFSI anion and anchoring of another TFSI to the PEO. This decreases the polymer conductivity near the cathode, making it easier to ionize additional PEO and leading to complete degradation of the battery. We refer to this as the Cathode Overpotential Driven Ionization of the Solvent (CODIS) model. We suggest possible ways to confirm experimentally our interpretation and propose modifications to suppress or reduce electrolyte degradation. PMID- 30283937 TI - Organic crystalline materials in flexible electronics. AB - Flexible electronics have attracted considerable attention recently given their potential to revolutionize human lives. High-performance organic crystalline materials (OCMs) are considered strong candidates for next-generation flexible electronics such as displays, image sensors, and artificial skin. They not only have great advantages in terms of flexibility, molecular diversity, low-cost, solution processability, and inherent compatibility with flexible substrates, but also show less grain boundaries with minimal defects, ensuring excellent and uniform electronic characteristics. Meanwhile, OCMs also serve as a powerful tool to probe the intrinsic electronic and mechanical properties of organics and reveal the flexible device physics for further guidance for flexible materials and device design. While the past decades have witnessed huge advances in OCM based flexible electronics, this review is intended to provide a timely overview of this fascinating field. First, the crystal packing, charge transport, and assembly protocols of OCMs are introduced. State-of-the-art construction strategies for aligned/patterned OCM on/into flexible substrates are then discussed in detail. Following this, advanced OCM-based flexible devices and their potential applications are highlighted. Finally, future directions and opportunities for this field are proposed, in the hope of providing guidance for future research. PMID- 30283938 TI - A carbon dots/rutin system for colorimetric and fluorimetric dual mode detection of Al3+ in aqueous solution. AB - In this work, colorimetric and fluorimetric dual mode detection of Al3+ in aqueous solution was achieved using a carbon dots/rutin (CDs/rutin) coexisting system. Upon addition of Al3+, a yellow Al(iii)-rutin complex was formed without any interaction between Al3+ and the carbon dots (CDs). As a result, a new absorption peak of the complex at 430 nm increased while the peak of rutin at 360 nm decreased. Therefore, a ratiometric colorimetric method for the detection of Al3+ was built on a good linear relationship between the absorbance ratio (A430 nm/A360 nm) and the concentration of Al3+ in a wide linear range from 2.0 to 40.0 MUM, with a limit of detection (LOD) as low as 0.38 MUM. More interestingly, the excitation spectrum of the CDs overlapped with the absorption band of the Al(iii) rutin complex, resulting in an inner filter effect on the fluorescence of the CDs. Accordingly, a fluorimetric approach was developed on an excellent linear relationship between (F0 - F)/F0 and the concentration of Al3+ in the range from 0.8 to 20.0 MUM, with an LOD of 0.32 MUM. Finally, the spiked Al3+ in real samples (tap water and lake water) was recovered by the as-proposed dual mode detection with high accuracy.

AB - Ionization-induced structural and conformational reorganization in various pi stacked dimers and covalently linked bichromophores is relevant to many processes in biological systems and functional materials. In this work, we examine the role of structural, conformational, and solvent reorganization in a set of conformationally mobile bichromophoric donors, using a combination of gas-phase photoelectron spectroscopy, solution-phase electrochemistry, and density functional theory (DFT) calculations. Photoelectron spectral analysis yields both adiabatic and vertical ionization energies (AIE/VIE), which are compared with measured (adiabatic) solution-phase oxidation potentials (Eox). Importantly, we find a strong correlation of Eox with AIE, but not VIE, reflecting variations in the attendant structural/conformational reorganization upon ionization. A careful comparison of the experimental data with the DFT calculations allowed us to probe the extent of charge stabilization in the gas phase and solution and to parse the reorganizational energy into its various components. This study highlights the importance of a synergistic approach of experiment and theory to study ionization induced structural and conformational reorganization.

AB - We report on direct measurement of all major ion-fragments and cluster-ions formed during high-energy electron impact of 2 keV on gaseous and condensed-phase pyridine. The ion-fragments of the parent pyridine cation are discussed in groups according to the number of atoms from the aromatic ring. The ion yield distributions within these groups show significant shifts towards higher masses for condensed pyridine compared to gaseous pyridine due to hydrogen migration. A wide spectrum of desorbed hydrogenated fragment-ions and ionic clusters with masses up to 320 u are observed for pyridine. The ion yields for the protonated parent molecule (C5H5NH+), the dehydrogenated dimer (C10H9N2+) and the dehydrogenated trimer (C15H12N3+) depend on the mass of the desorbing ionic clusters. The strongest cluster signals are assigned to binding between the parent cation and subunits of the pyridine molecule. Quantum-chemical calculations reveal that the formation of a bond between the pyridine molecules and a carbenium ion is crucial for the stability of selected cluster ions.

AB - The trap states at the interface between perovskite and charge-transport layer have a great influence on the performance of perovskite solar cells. Here, a high efficiency MAPbI3-xClx perovskite solar cell has been demonstrated, by introducing a thin layer of LiF or PbF2 between the SnO2/perovskite. Improved charge collection and reduced interfacial charge recombination are realized, leading to remarkable rises of both open-circuit voltage (Voc) and short-circuit current (Jsc). This successful interfacial passivation paved a new way to fabricate high performance perovskite solar cells with large Voc.

AB - We have immobilized poly(ethylene glycol) (PEG) on the surfaces of poly(lactic-co glycolic acid) (PLGA) nanoparticles by two different chemical methods, i.e., SOCl2 halogenate-alcoholysis and DCC dehydration. The immobilized PLGA nanoparticles were characterized by DLS, 1H NMR, FT-IR and laser trapping/confocal Raman spectroscopic techniques. As a result, especially the Raman spectra which were measured after optically trapping ca. 10 individual nanoparticles in solution indicated that the PLGA nanoparticles were successfully immobilized with the PEG by the chemical methods.

AB - Dark tea has a significant effect on the prevention and treatment of age-related degenerative diseases. At present, further exploration of its functional mechanisms is delayed because of the complexity of post-fermentation microbial metabolites during the production phase. In this study, new isolated microbial metabolites extracted from dark tea were used to explore the neuroprotective effects, and they also helped allow further exploration of the mechanism of dark tea. Taking senescence-accelerated mouse prone 8 (SAMP8) mice as a biological model, we examined the protective effect on brain neurons of post-fermentation microbial metabolites which were extracted from dark tea. The 4-month-old mice were given treatments of the same concentration (10 mg kg-1 d-1) which were l theanine, 3,3'-azanediylbis(4-hydroxybenzoic acid) (CDT-1) and one of the 8-C N ethyl-2-pyrrolidinone substituted flavan-3-ols (CDT-2) by gavage for 14 weeks. Relative measurements such as RT-PCR, ELISA, western blotting, and section staining (HE, Nissl and myelin) were carried out. The results showed that l theanine, CDT-1 and CDT-2 could inhibit the decrease in body weight, and down regulate the formation of 4-HNE and ubiquitinated protein aggregates and the Abeta metabolic pathway. They could also increase endogenous antioxidant capacity, relieve cell hypoxia, and reduce the rate of neuronal apoptosis. This means that their protective activity regarding SAMP8 neurons was excellent and the activity of CDT-2 was the most significant. PMID- 30283946 TI - Gd3+-Ion-induced carbon-dots self-assembly aggregates loaded with a photosensitizer for enhanced fluorescence/MRI dual imaging and antitumor therapy. AB - The development of multifunctional nanoparticles for tumor theranostics has become a research hotspot. Despite the advantages of non-invasive precision diagnostics and efficient drug-delivery, these nanoparticles bring two significant issues: (i) a potential toxic effect and (ii) difficult clearance. To solve these issues, carbon dots (C-dots) are key potential candidates owing to their unique properties, such as excellent biocompatibility and rapid renal clearance. However, their small size leads to a short circulation time in the blood, which causes non-sufficient tumor accumulation for antitumor therapy. To reach the balance between an efficient accumulation in a tumor and rapid clearance from the body, herein we report a new multifunctional nanoprobe: photosensitizer (chlorine e6, Ce6)-loaded assembled C-dots (A-C-dots@Ce6). The A C-dots@Ce6 were assembled from negatively-charged discrete C-dots using Gd3+ ions as a "glue". which also provided another function of in vivo nanoprobe monitoring via magnetic resonance (MR) imaging. Moreover, the nanoprobe exhibited an acidic pH-dependent disassembly and drug-release property. Benefiting from these advantages, the nanoprobe showed a targeted antitumor effect in A549 tumor bearing mice under laser irradiation and gradual disassembly in the tumor for later body clearance. Therefore, the nanoprobe potentially provides a new strategy to solve the above balance issue, and brightens the future for antitumor monitoring and treatment.

AB - Ozonolysis of TMS-substituted olefins produces alpha-carbonyl TMS peroxides without cleavage of the C[double bond, length as m-dash]C bond. Herein, stereochemistry in the ozonolysis was studied using silyl derivatives of (E)- and (Z)-(1-TMS)alk-1-en-3-ols. The (E)-isomers afforded the anti-3-siloxy-2-(TMS oxy)aldehydes as the major stereoisomer (anti/syn = 3-9 : 1) after reductive work up with Ph3P. In contrast, Z-olefins selectively gave the syn isomers with syn/anti ratios of 4-19 : 1. Facial selection was speculated based on the Cieplak effect. This ozonolysis was successfully applied for the synthesis of 14R,15S- and 14S,15S-diHETEs (anti and syn isomers, respectively) in enantioenriched forms.

AB - Two molecules of tetra(4-pyridyl)cavitand 1 and four molecules of isophthalic acid linker 2a with a triethylene glycol monomethyl ether (TEG) group self assembled into a six-component capsule 12.2a4 through eight pyNHO2C hydrogen bonds, which encapsulates one molecule of guest G such as bis(4 acetoxyphenyl)acetylene and hexakis(4-iodophenyl)benzene to form G@(12.2a4). Guest-encapsulation ability and selectivity of 12.2a4 were revealed. trans-5-(p Substituted-phenylazo)isophthalic acid with two dichotomous branching TEG groups trans-2b serves as a photoresponsive linker to form 12.(trans-2b)4, which moderately reduced guest-encapsulation ability upon photoisomerization (at the photostationary state, 10% guest release upon subunit-trans-2b/subunit-cis-2b = 18 : 82). PMID- 30283950 TI - Tuning the order of colloidal monolayers: assembly of heterogeneously charged colloids close to a patterned substrate. AB - We study the behavior of negatively charged colloids with two positively charged polar caps close to a planar patterned surface. The competition between the different anisotropic components of the particle-particle interaction is able by itself to give rise to a rich assembly scenario: colloids with charged surface patterns already form different crystalline domains when adsorbed to a homogeneously charged substrate. Here we consider substrates composed of alternating (negative/neutral, positive/neutral and positive/negative) parallel stripes and, by means of Monte Carlo simulations, we investigate the ordering of the colloids on changing the number of the stripes. We show that the additional competition between the two different lengths scales characterizing the system (i.e., the particle interaction range and the size of the stripes) gives rise to a plethora of distinct particle arrangements, where some well-defined trends can be observed. By accurately tuning the substrate charged motif it is possible to, e.g., promote specific particle arrangements, disfavor crystalline domains or induce the formation of extended, open clusters.

The wise use of scaling laws shows the advantages of working with sub-microliter sized samples. Rapid progress in MEMS technologies has driven the design of integrated platforms performing many biochemical operations. Here we report a new concentrator device based on electro-hydrodynamic forces which can be easily integrated into electrowetting-on-dielectric (EWOD) platforms. This approach is label-free and applicable to a wide range of micro-objects. The detection and analysis of two common waterborne parasites, Cryptosporidium and Giardia, is a perfect test case due to their global health relevance. By fully controlling the interplay of the various forces acting on the micron-sized Cryptosporidium parvum and Cryptosporidium muris oocysts, we show that it is possible to concentrate them on the side of a 10 MUL initial drop and then extract them efficiently from a droplet of a few hundred nanoliters. We performed a finite element modeling of the forces acting on the parasites' oocysts to optimize the electrodes' shapes. We obtained state-of-the-art concentration factors of 12 +/- 0.4 times and 2 to 4 times in the sub-region of the drop and the extracted droplet, respectively, with an efficiency of 70 +/- 6%. Furthermore, this device had the ability to selectively concentrate parasites of different species out of a mix. We demonstrated this by segregating C. parvum oocysts from either Giardia lamblia cysts or its related species, C. muris oocysts.

AB - Iodothiocyanation of alkynes with ammonium thiocyanate (NH4SCN) and molecular iodine (I2) has been demonstrated in aqueous ethanol, which enables efficient synthesis of a series of functional beta-iodo vinylthiocyanates in good to excellent yields under mild reaction conditions without the need for any protection.

AB - Phosphorus-containing indole derivatives represent a special class of phosphorus containing nitrogen heterocycles, which not only widely exist in pharmaceutical agents, but also have widespread applications in materials science and organic synthesis as ligands and intermediates. The synthesis of such compounds is of current interest, with two major synthetic strategies being established. This review summarizes the recent progress in this field, including the advantages and limitations of each subdivisional tactic, briefly discusses the reaction mechanisms and challenges, and outlines the synthetic opportunities still open. PMID- 30283955 TI - Modeling coupled kinetics of antimony adsorption/desorption and oxidation on manganese oxides. AB - Understanding the kinetic reactions of antimony (Sb) at the MnO2-water interface is essential for predicting the dynamic behavior of Sb in soil environments. In this study, we developed a quantitative model for assessing the coupling between Sb(iii) oxidation and Sb(iii)/Sb(v) adsorption/desorption kinetics and the role of each individual reaction process in controlling the overall reaction rates. Based on our modeling results, Sb(iii) oxidation rates were very fast at the early stages of the reactions and may significantly slow down with time, and Sb(iii) and Sb(v) showed different adsorption behavior on delta-MnO2. Our kinetics model is able to account for different adsorption/desorption kinetics of Sb(iii) and Sb(v) and the changes of Sb(iii) oxidation rates during the coupled kinetic processes, which provides a general modeling framework for predicting Sb kinetic behavior at the MnO2-water interface.

AB - N,C,N-Chelated pnictinidenes ArE [where E = As, Sb or Bi; Ar = 2,6-(tBuN[double bond, length as m-dash]CH)2C6H3] were used as ligands for the coordination of various gold(i) complexes. Thus, the reaction of ArE with [AuCl(Me2S)] gave complexes [AuCl(ArE)] [where E = As (1) or Sb (2)] that exhibited only limited stability in solution. By contrast, the reaction of ArBi with [AuCl(Me2S)] led to the immediate deposition of gold metal and the oxidation of the bismuth atom giving ArBiCl2. The treatment of a tetrameric gold alkynyl complex [Au(C[triple bond, length as m-dash]CPh)]4 with ArAs and ArSb gave ionic compounds [Au(ArAs)2]+[Au2(C[triple bond, length as m-dash]CPh)3]- [denoted as 3+[Au2(C[triple bond, length as m-dash]CPh)3]-] and [Au(ArSb)2]+[Au(C[triple bond, length as m-dash]CPh)2]- [denoted as 4+[Au(C[triple bond, length as m dash]CPh)2]-], respectively. Finally, the reaction of ArE with the carbene gold(i) complex [Au(IPr)(MeCN)]+[BF4]- [where IPr = 1,3-bis(2,6 diisopropylphenyl)imidazolin-2-ylidene, MeCN = acetonitrile] produced ionic complexes [Au(IPr)(ArE)]+[BF4]- [for cations: E = As (5+), Sb (6+) or Bi (7+)]. All complexes were characterized using 1H and 13C NMR, high mass accuracy electrospray ionization mass spectrometry (ESI-MS), IR and Raman spectroscopy and (except for 1) by single-crystal X-ray diffraction analysis. Furthermore, the structure and bonding of both neutral and ionic complexes with different coordination patterns have also been investigated in detail using a Density Functional Theory (DFT) computational approach.

AB - A one-pot, regiospecific synthesis of dihydrofurans bearing a quaternary centre and tetrasubstituted furans is developed from the formal [3 + 2] annulation of tert-propargyl alcohols and 1,3-diketones under Ca(ii)/DBU conditions. The reaction proceeds through the SN2I mechanism to form homoallenyl ketone and a subsequent cycloisomerization to yield novel and new chemical entities of privileged scaffolds. PMID- 30283957 TI - Flexible and enhanced multicolor-emitting films co-assembled by lanthanide complexes and a polymerizable surfactant in aqueous solution. AB - Lanthanide complex doped lyotropic liquid crystals (LLCs) are soft materials which are impressive due to their excellent luminescence efficiencies and stabilities. The introduction of lanthanide complexes into polymerizable LLCs, however, may produce organized films with better optical and mechanical properties through in situ photopolymerization. An environmentally friendly strategy to fabricate flexible multicolor-emitting films has been developed through co-assembling red-/green-emitting trisdipicolinate lanthanide complexes [choline]3[Ln(DPA)3] (Ln-DPA, Ln = Eu, Tb) into LLC matrices mainly via electrostatic interaction and further photopolymerization. The LLCs were constructed from a polymerizable surfactant, 3-dodecyl-1-vinylimidazolium bromide (C12VIMBr), in aqueous solution. The maintenance of the well-defined LLC nanostructures in the luminescent films was validated by small-angle X-ray scattering (SAXS) as well as scanning electron microscopy (SEM) measurements. Remarkably, the lifetime and absolute luminescence quantum efficiency of such films have been improved significantly compared with those of the corresponding solid Eu-DPA complex or in aqueous solution and LLC matrices. Through tuning the molar ratio of Eu-DPA to Tb-DPA complexes, the emission color of the films could be finely-tailored between red and green in the CIE chromaticity diagram. Furthermore, the films also possessed certain mechanical strength and stability against pH, metal ions, and temperature, indicating their potential application as robust luminescent materials.

Some of these mechanisms will be discussed, including the most common, that of drug phototoxicity. Different types of photosensitivity are addressed with respect to clinical presentation, mechanisms and additionally the contribution to our understanding through clinically directed investigations and regulatory requirements. Repeated controlled therapeutic use of drug phototoxicity, with psoralen-UVA (PUVA) photochemotherapy and photodynamic therapy (PDT) will also be discussed. Finally, the potential for drug-induced photocarcinogenesis will also be covered. PMID- 30283960 TI - Electrochemical impedance spectroscopy reveals a new mechanism based on competitive binding between Tris and protein on a conductive biomimetic polydopamine surface. AB - A novel mechanism was developed to study the interaction of mussel inspired polydopamine surfaces with bovine serum albumin using cyclic voltammetry and electrochemical impedance spectroscopy supplemented with XPS, IR spectroscopy, UV spectroscopy and atomic force microscopy. The polydopamine surfaces reveal different mechanisms that give a new insight into understanding the interaction with BSA under the variable conditions used for PDA preparation and BSA adsorption. The study provides an in-depth analysis of the orientations and interactions of BSA with polydopamine surfaces. The protein interaction behavior changed significantly in different environments including different pH values and concentrations of buffer and it revealed a competitive binding mechanism of protein binding. The study provides an outlook for studying the interaction of protein foulants with PDA, which should be carried out in nucleophilic buffers, while the covalent binding or immobilization of biomolecules to PDA surfaces should be carried out in non-nucleophilic buffer for higher efficiency. PMID- 30283961 TI - Hole transporting materials for perovskite solar cells: a chemical approach. AB - Photovoltaic solar cells based on perovskites have come to the forefront in science by achieving exceptional power conversion efficiencies (PCEs) in less than a decade of research. This "still young" generation of solar cells is currently rivalling, in PCEs, well-established technologies, such as cadmium telluride (CdTe) and silicon. Further improvements in device stability by means of innovative materials are yet to come, with technology becoming closer to meeting the market requirements. Emerging from this groundbreaking discovery, a great number of charge transporting materials have flourished, which is particularly true for hole transporting materials (HTMs). The huge number of molecules prepared stem from design and engineering of a wide variety of new and also chemically modified old molecules where organic synthesis has played a fundamental role. In this review, the contribution of chemistry through those synthetic protocols used for producing new and innovative HTMs from relatively simple organic molecules is presented in a rational and systematic manner. The variety and impact of synthetic strategies followed, the structure-property relationship and stability, conductivity and device performance are highlighted from a chemical viewpoint. PMID- 30283962 TI - Manipulating cell fate: dynamic control of cell behaviors on functional platforms. AB - The cell microenvironment choreographs the behaviors of cells through multiple well-controlled signals. For basic biological study and cell-based therapies, it is essential to decipher the complicated cell-matrix interactions, and to develop ways to mimic the dynamic microenvironment so that desired biological functions of cells can be guided. For this, biomaterials with the ability to spatiotemporally impart biochemical and biophysical cues to manipulate cell fate have been developed recently. The dynamic property and programmable features of stimuli-responsive biointerfaces endow them with the outstanding ability to develop advanced biological systems. In this review, we illustrate the recent progress of stimuli-responsive biosystems with a particular emphasis on their explorations for cell-based fundamental studies, disease diagnosis and regenerative therapy. Some basic principles and strategies for the design of dynamic platforms are also discussed in this review. Finally, we conclude with an outlook on current challenges and future of dynamic platforms for cell study and biomedical applications. Overall, we anticipate that this review will boost the development of dynamic and multifunctional biosystems by inspiring interest from various disciplines, including chemistry, materials science, cell biology, nanotechnology, biomedical engineering, as well as clinical research.

AB - In this work, we decorated the surface of MSNs by a one-pot Passerini reaction using near-infrared fluorescence BODIPY and poly(ethylene glycol) with an aldehyde group (PEG-CHO) for the first time. Doxorubicin (Dox) was loaded to demonstrate the reduction response. The formed MSNs neatly integrate chemotherapy, photothermal therapy and near-infrared fluorescence (NIRF) imaging. PMID- 30283964 TI - Formation of polyhedral vesicle gels from catanionic mixtures of hydrogenated and perfluorinated surfactants: effect of fluoro-carbon alkyl chain lengths. AB - The effects of alkyl chain length of anionic fluorinated fatty acid surfactants, CnF2n+1COOH (n = 7-11), mixed with one cationic hydrocarbon surfactant, tetradecyltrimethylammonium hydroxide (TTAOH), on the formation of polyhedral vesicle gels were investigated in aqueous solutions. On the basis of phase behavior mapping, C8F17COOH, C9F19COOH, C10F21COOH and C11F23COOH except C7F15COOH all formed polyhedral vesicle gels when they were mixed with TTAOH under certain mixed ratios, which was demonstrated by freeze-fracture transmission electron microscopy (FF-TEM) measurements. Meanwhile, the following observation was not observed: the longer the fluorinated alkyl chain, the more effective the formation of gels by fluorinated fatty acids. The formation of the faceted vesicle gels was determined both by the rigidity of the fluorinated alkyl chain and the co-crystallization of fluorocarbon chains and hydrocarbon chains, as revealed by the results of differential scanning calorimetry (DSC), wide angle X-ray scattering (WAXS) and 19F NMR measurements. Furthermore, the polyhedral vesicle gels showed high viscoelasticity, which increased clearly with increasing fluorinated alkyl chain length, indicating that the viscoelastic property of the polyhedral vesicle gel was a result of the crystalline state of the polyhedral vesicle bilayers at room temperature. As far as we know, such polyhedral vesicle gels formed from perfluorinated and hydrocarbon surfactant mixtures have been rarely reported. Our study can be a great advancement in fundamental research of surfactant vesicle gels. PMID- 30283965 TI - The cyclo-Sb6 ring in the [Sb6(RuCp*)2]2- ion. AB - The [Sb6(RuCp*)2]2- (1) anion represents the first example of a Zintl cluster with a boat-like cyclo-Sb6 subunit and the first ruthenium polyantimonide complex. The anion is dynamic in solution and fragments in the gas phase. Structural parameters and DFT calculations suggest the possibility of Sb[double bond, length as m-dash]Sb double bond character. PMID- 30283966 TI - A hexadecanuclear silver alkynyl cluster based NbO framework with triple emissions from the visible to near-infrared II region. AB - Compared to emissive silver-thiolate clusters, their alkynyl cousins are, however, usually luminescence silent. Herein we report a novel silver-alkynyl cluster based NbO-type framework (SD/Ag18) showing unprecedented triple emission spanning from the visible to near-infrared (NIR) region. It is a 3D framework constructed from a [Cl@Ag16] cluster based unit, which is further quadruply bridged by the surrounding four Ag atoms through AgAg interactions, giving a 4 connected NbO topology. Although SD/Ag18 exhibits weak orange-red emission at room temperature, its emission becomes strong upon cooling, with three emission maxima at 524, 647 and 1036 nm, respectively, covering both the visible and NIR regions. The visible emissions involve triplet alkynyl-to-metal charge transfer mixed with a cluster-centered state, whereas the participation of cPrC[triple bond, length as m-dash]C- in the frontier orbitals of the cluster may be responsible for the NIR emission. The unusual emissions, especially in the NIR-II region, are observed, for the first time, in silver complexes. PMID- 30283967 TI - First enantioselective total synthesis of altersolanol A. AB - The first enantioselective total synthesis of altersolanol A, a secondary metabolite from the endophytic fungi Stemphylium globuliferum and Alternaria solani, is described. The key step towards the tetrahydroanthraquinone core was an asymmetric Diels-Alder (D-A) cycloaddition promoted by (R)-3,3'-diphenyl BINOL/boron Lewis acid with good to excellent yields and excellent diastereo- and enantioselectivity (>95 : 5 dr and 98 : 2 er). PMID- 30283968 TI - Metal-free synthesis of fulleropyrrolidin-2-ols: a novel reaction of [60]fullerene with amines and 2,2-disubstituted acetaldehydes. AB - A series of scarce fulleropyrrolidin-2-ols were synthesized by the facile one step reaction of [60] fullerene with inexpensive and readily accessible amines and 2,2-disubstituted acetaldehydes without the addition of valuable metal salts in moderate yields, comparable to those for most monoadducts reported previously. This strategy exhibits a broad substrate scope and excellent functional group tolerance. A plausible reaction pathway for the formation of fulleropyrrolidin-2 ols is proposed to elucidate the above reaction process. PMID- 30283969 TI - Investigation on the growth mechanism of SiC whiskers during microwave synthesis. AB - Silicon carbide (SiC) whiskers with different morphologies are fabricated by microwave heating of SiO2-coated coal mineral particles at different temperatures and different holding times in an oxygen-containing environment. The atomic diffusion processes and growth mechanism of the SiC whiskers are simulated. It is found that a closed capsule of SiO2 appears during microwave heating, within which the SiC whiskers are formed. SiC crystals can be prepared at 1100 degrees C for 10 min. The optimized synthesis condition is approximately 1100 degrees C for 20 min. Higher temperatures or/and holding times lead to the re-oxidation of the SiC crystals. A layer of amorphous SiO2 wraps around the SiC whisker surface and generates coated composites at all temperatures. Crystallite knots are observed embedding on the SiC whiskers at 1300 degrees C due to the surface cleaning and activating effects of microwave plasma. The knots are smoothed at 1500 degrees C due to local atomic diffusion and grain growth motivated by the microwave coupling effect. The variations in the microwave plasma and the coupling effect at different heating stages also give rise to unique growth phenomena. For the sample synthesized at 1100 degrees C for 20 min, the high permittivity values present in the SiC whiskers lead to the excellent EM absorption properties at high frequency.

AB - An efficient one-pot approach for the synthesis of polyfunctionalized quinolines was developed via a sequence of copper-catalyzed coupling reaction/propargyl allenyl isomerization/aza-electrocyclization. Easily available starting materials, mild conditions, and a wide substrate scope make this approach potentially useful. PMID- 30283971 TI - First principles studies of the interactions between alkali metal elements and oxygen-passivated nanopores in graphene. AB - We characterize the structure-property relationship of alkali metal elements in oxygen-passivated graphene pores using the density functional theory that accounts for quantum mechanical effects and charge transfer. Our description is based on the structural and electronic properties of the system and shows common trends among the different alkali metals and pores. We find that these nanopores which serve as docking sites for alkali metal elements give the strongest binding when the size of the pore is similar to the element's van der Waals radius. A linear correlation between the binding energy and the energy location of the alkali element valence state is found for all elements and pores. Analysis of the charge transfer reveals that alkali adsorption increases the local charge in the perimeters of the pore by amounts that depend on the geometry. Moreover, charge distributions in pristine graphene resemble those of an ideal conductor despite its semimetallic character and atomic thickness while oscillations in the vicinity of O-passivated nanopores are observed. Our results suggest that charge transfer is localized within a few nanometers of the pore and, therefore, allude to high density energy storage. The outcomes of this work are significant towards the application of porous graphene as effective membranes for ion filtration of water and electrode applications. PMID- 30283972 TI - Hydration of 3-hydroxy-4,4-dimethylglutaric acid with dimethylamine complex and its atmospheric implications. AB - Atmospheric aerosols have a tremendous influence on visibility, climate, and human health. New particle formation (NPF) is a crucial source of atmospheric aerosols. At present, certain field observations and experiments have discovered the presence of 3-hydroxy-4,4-dimethylglutaric acid (HDMGA), which may participate in NPF events. However, the nucleation mechanism of HDMGA has not been clearly understood. In addition, dimethylamine (DMA) is an important precursor of nucleation. The nucleation mechanism involving HDMGA and DMA has not been studied. In this study, the most stable structures of (HDMGA)(H2O)n (n = 0 3) and (HDMGA)(DMA)(H2O)n (n = 0-3) were obtained by using M06-2X coupled with the 6-311++G(3df,3pd) basis set. The alpha-carboxyl group is directly attached to the amino group in all the most stable configurations. Proton transfer enhances the strength of a hydrogen bond, as well as promotes the generation of a global minimum structure. Temperature has a considerable influence on the distribution of isomers for (HDMGA)(DMA)(H2O)3 as compared to the other investigated clusters. The Gibbs free energy values reveal that most of the clusters can exist in NPF, except for (HDMGA)(H2O)1. The process of adding a cluster of (H2O)n more likely occurs in the atmosphere than gradually adding a single water molecule. PMID- 30283973 TI - Hard convex lens-shaped particles: metastable, glassy and jammed states. AB - We generate and study dense positionally and/or orientationally disordered, including jammed, monodisperse packings of hard convex lens-shaped particles (lenses). Relatively dense isotropic fluid configurations of lenses of various aspect ratios are slowly compressed via a Monte Carlo method based procedure. Under this compression protocol, while 'flat' lenses form a nematic fluid phase (where particles are positionally disordered but orientationally ordered) and 'globular' lenses form a plastic solid phase (where particles are positionally ordered but orientationally disordered), 'intermediate', neither 'flat' nor 'globular', lenses do not form either mesophase. In general, a crystal solid phase (where particles are both positionally and orientationally ordered) does not spontaneously form during lengthy numerical simulation runs. In correspondence to those volume fractions at which a transition to the crystal solid phase would occur in equilibrium, a 'downturn' is observed in the inverse compressibility factor versus volume fraction curve beyond which this curve behaves essentially linearly. This allows us to estimate the volume fraction at jamming of the dense non-crystalline packings so generated. These packings are nematic for 'flat' lenses and plastic for 'globular' lenses, while they are robustly isotropic for 'intermediate' lenses, as confirmed by the calculation of the tau order metric, among other quantities. The structure factors S(k) of the corresponding jammed states tend to zero as the wavenumber k goes to zero, indicating they are effectively hyperuniform (i.e., their infinite-wavelength density fluctuations are anomalously suppressed). Among all possible lens shapes, 'intermediate' lenses with aspect ratio around 2/3 are special because they are those that reach the highest volume fractions at jamming while being positionally and orientationally disordered and these volume fractions are as high as those reached by nematic jammed states of 'flat' lenses and plastic jammed states of 'globular' lenses. All of their attributes, taken together, make such 'intermediate' lens packings particularly good glass-forming materials. PMID- 30283974 TI - Preparation and characterization of pyrene modified uridine derivatives as potential electron donors in RNA. AB - Charge transfer across double stranded DNA was observed for the first time about 20 years ago, and ever since it has been the subject of a large number of studies. RNA has been hardly investigated in this regard, which not least is due to the lack of suitably functionalized ribonucleotide building blocks to serve as electron sources upon incorporation into oligoribonucleotides. We have synthesized two uridine derivatives carrying pyrene or dimethylaminopyrene linked to C5 of the nucleobase. The key to successful synthesis was the adaptation of Suzuki-Miyaura conditions to the coupling of the pyrene moiety with the ribonucleoside. Final decoration of the pyrenylated nucleosides with standard 5' O- and 2'-O-protecting groups and subsequent 3'-O-phosphitylation delivered the building blocks for incorporation into RNA. Spectroscopic analysis of the two pyrenylated uridines and of the accordingly modified oligonucleotides showed that in particular the dimethyaminopyrene functionalized nucleoside is a promising candidate as an electron source for RNA charge transport studies. PMID- 30283975 TI - Surgical trends and patient factors associated with the treatment of apical pelvic organ prolapse from a national sample. AB - INTRODUCTION AND HYPOTHESIS: Prolapse of the vaginal apex can be treated using multiple surgical modalities. We describe national trends and patient characteristics associated with the surgical approach and compare perioperative outcomes of abdominal versus vaginal repair of apical pelvic organ prolapse (POP). METHODS: The 2006-2012 National Surgical Quality Improvement Program Database was queried for abdominal sacrocolpopexy (ASC) and vaginal apical suspensions. Patients were stratified by whether or not concomitant hysterectomy (CH) was performed or whether or not they were post-hysterectomy (PH). Multivariate logistic regressions were adjusted for confounding variables. RESULTS: A total of 6,147 patients underwent apical POP repair: 33.9% (2,085) ASCs, 66.1% (4,062) vaginal suspensions. 60.0% (3,689) underwent CH. In all cohorts, older patients were less likely to have ASC (CH: OR 0.48, CI 0.28-0.83, p = 0.008 for age >= 60; PH: OR 0.28, CI 0.18-0.43, p < 0.001). Over time, the proportion of all vaginal and abdominal repairs remained relatively stable. Use of minimally invasive ASC, however, increased over the study period (trend p < 0.001), and use of mesh for vaginal suspensions decreased (p < 0.001). ASC had a longer median operative time (PH 174 vs 95 min, p < 0.001; CH 192 vs 127 min, p < 0.001). Complication rates were the same for vaginal repairs and ASC, overall and when sub-stratified by hysterectomy status. CONCLUSIONS: Nationally, most apical POP repairs are performed via a vaginal route. Older age was predictive of the vaginal route for both CH and PH groups. ASCs had longer operative times. There has been increased utilization of minimally invasive ASC and decreased use of mesh-augmented vaginal suspensions over time. PMID- 30283976 TI - Potential application of cell reprogramming techniques for cancer research. AB - The ability to control the transition from an undifferentiated stem cell to a specific cell fate is one of the key techniques that are required for the application of interventional technologies to regenerative medicine and the treatment of tumors and metastases and of neurodegenerative diseases. Reprogramming technologies, which include somatic cell nuclear transfer, induced pluripotent stem cells, and the direct reprogramming of specific cell lineages, have the potential to alter cell plasticity in translational medicine for cancer treatment. The characterization of cancer stem cells (CSCs), the identification of oncogene and tumor suppressor genes for CSCs, and the epigenetic study of CSCs and their microenvironments are important topics. This review summarizes the application of cell reprogramming technologies to cancer modeling and treatment and discusses possible obstacles, such as genetic and epigenetic alterations in cancer cells, as well as the strategies that can be used to overcome these obstacles to cancer research. PMID- 30283977 TI - Dynamics and mechanisms of posterior axis elongation in the vertebrate embryo. AB - During development, the vertebrate embryo undergoes significant morphological changes which lead to its future body form and functioning organs. One of these noticeable changes is the extension of the body shape along the antero-posterior (A-P) axis. This A-P extension, while taking place in multiple embryonic tissues of the vertebrate body, involves the same basic cellular behaviors: cell proliferation, cell migration (of new progenitors from a posterior stem zone), and cell rearrangements. However, the nature and the relative contribution of these different cellular behaviors to A-P extension appear to vary depending upon the tissue in which they take place and on the stage of embryonic development. By focusing on what is known in the neural and mesodermal tissues of the bird embryo, I review the influences of cellular behaviors in posterior tissue extension. In this context, I discuss how changes in distinct cell behaviors can be coordinated at the tissue level (and between tissues) to synergize, build, and elongate the posterior part of the embryonic body. This multi-tissue framework does not only concern axis elongation, as it could also be generalized to morphogenesis of any developing organs.

AB - Oxazolidine derivatives (OxD) are five ring-membered compounds that contain at least one oxygen and nitrogen in their molecular structure. OxD are known due to several therapeutic activities such as anticancer and antibiotic properties. In this paper, we performed a thermodynamic analysis of the mixed films composed by dipalmitoylphosphatidylglycerol (DPPG), dipalmitoylphosphoethanolamine (DPPE), dipalmitoyl phosphatidylcholine (DPPC) or L-alpha phosphatidylcholine (PC) with a novel oxazolidine derivate (OxD). Relevant thermodynamic parameters such as excess areas (DeltaAE), excess free energies (DeltaG), and Gibbs free energy of mixing (AGmix) were derived from the surface pressure data. The topographical analysis was performed using atomic force microscopy. Based on the calculated values of the thermodynamic parameters, we observed that the miscibility of the mixed films was directly dependent on their composition. DPPG/OxD and DPPE/OxD systems present the best-mixed character at low pressures at OxD molar fraction equivalent to 0.25. PMID- 30283980 TI - No significant impact of patient age and prior treatment profile with docetaxel on the efficacy of cabazitaxel in patient with castration-resistant prostate cancer. AB - BACKGROUND: The correlation of the oncological outcomes of docetaxel and cabazitaxel in Japanese metastatic castration-resistant prostate cancer (mCRPC) patients has not been unclear. MATERIALS AND METHODS: This study included a total of 47 consecutive Japanese mCRPC patients treated with cabazitaxel and assessed the prognostic significance of cabazitaxel, focusing on patient age and the correlation of efficacy between docetaxel and cabazitaxel. RESULTS: Prostate specific antigen (PSA) decline was observed in 27 patients (57.4%), including 19 (40.0%) achieving the response defined by PSA decline >= 30%. The median overall survival (OS) periods after the introduction of cabazitaxel was 16.1 months. Twenty (42.6%) were judged to have responded to cabazitaxel with a PSA decrease >= 30% from the baseline. A 30% PSA response to cabazitaxel was achieved in 4 (50.0%) patients with ? 75 years (n = 8) and 16 (41.0%) patients with less than 75 years (n = 39). There was no significant correlation between the PSA response and patients' age (p = 0.707). A 30% PSA response to cabazitaxel was achieved in 13 (46.4%) and 7 (36.8%) patients with and without that to docetaxel, respectively. A 30% PSA response to cabazitaxel was achieved in 5 (16.6%) and 7 (41.2%) patients who had treated with less than 10 cycles docetaxel or 10 ? cycles, respectively. Univariate and multivariate analyses revealed that there were no significant correlation of patient age (p = 0.537), the response to prior docetaxel therapy (p = 0.339) or cycles of docetaxel therapy (p = 0.379) with shorter OS. CONCLUSION: These results indicate that the introduction of cabazitaxel for Japanese mCRPC patients could result in oncological outcomes without any association with patient's age and the profiles of previous docetaxel therapy.

AB - Transposable elements represent the DNA fragments capable of increasing their copy number and moving within the genome. Class II mobile elements represents the DNA transposons, which transpose via excision and the subsequent reinsertion at random genomic loci. The increase of their copy number occurs only when the transposition event is coupled with the replication. IS630/Tc1/mariner DNA transposon superfamily is one of the largest and widely distributed among the Class II elements. In this work, we provide a detailed analysis of IS630/Tc1/mariner DNA transposons from the Pacific oyster, Crassostrea gigas. IS630/Tc1/mariner transposons represented in the genome of the Pacific oyster belong to four families, Tc1 (DD34E), mariner (DD34D), pogo (DDxD), and rosa (DD41D). More than a half of IS630/Tc1/mariner elements from C. gigas belong to Tc1 family. Furthermore, Mariner-31_CGi element was shown to represent a new and previously unknown family with DD37E signature. We also discovered the full-size transcripts of eight elements from Tc1, mariner, and pogo families, three of which can, presumably, retain their transposition activity.

AB - Breast cancer remains one of the leading causes of cancer-associated death worldwide. Conventional treatment is associated with substantial toxicity and suboptimal efficacy. We, therefore, developed and evaluated the in vitro efficacy of an autologous dendritic cell (DC) vaccine to treat breast cancer. We recruited 12 female patients with stage 1, 2, or 3 breast cancer and matured their DCs with autologous tumour-specific lysate, a toll-like receptor (TLR)-3 and 7/8 agonist, and an interferon-containing cocktail. The efficacy of the vaccine was evaluated by its ability to elicit a cytotoxic T-lymphocyte response to autologous breast cancer cells in vitro. Matured DCs (>= 60% upregulation of CD80, CD86, CD83, and CCR7) produced high levels of the Th1 effector cytokine, IL12-p70 (1.2 ng/ml; p < 0.0001), compared to DCs pulsed with tumour lysate, or matured with an interferon containing cocktail alone. We further showed that matured DCs enhance antigen specific CD8 + T-cell responses to HER-2 (4.5%; p < 0.005) and MUC-1 (19%; p < 0.05) tetramers. The mature DCs could elicit a robust and dose-dependent antigen specific cytotoxic T-lymphocyte response (65%) which was tumoricidal to autologous breast cancer cells in vitro compared to T-lymphocytes that were primed with autologous lysate loaded-DCs (p < 0.005). Lastly, we showed that the mature DCs post-cryopreservation maintained high viability, maintained their mature phenotype, and remained free of endotoxins or mycoplasma. We have developed a DC vaccine that is cytotoxic to autologous breast cancer cells in vitro. The tools and technology generated here will now be applied to a phase I/IIa clinical trial. PMID- 30283981 TI - The effects of six-day SSRI administration on diurnal cortisol secretion in healthy volunteers. AB - RATIONALE: Hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis has been widely reported in depression, and evidence suggests that selective serotonin reuptake inhibitors (SSRIs) might exert their therapeutic effects through altering cortisol secretion. OBJECTIVE: This study assessed the effects of SSRI administration on diurnal cortisol secretion in healthy volunteers. METHODS: Sixty-four healthy men and women were randomised to receive either 10 mg escitalopram or placebo for six days in a double-blind fashion. On day six of medication, saliva samples were obtained at home for measurement of diurnal cortisol parameters (cortisol slope, cortisol awakening response, total daily cortisol output). RESULTS: Women receiving escitalopram had significantly steeper cortisol slopes across the day compared with those receiving placebo (F(1, 36) = 7.54, p = 0.009). This alteration in cortisol slope was driven by increases in waking cortisol levels (F(1, 35) = 9.21, p = 0.005). Escitalopram did not have any significant effect on the cortisol awakening response or the total daily cortisol output. CONCLUSIONS: Flattened cortisol slopes have been seen in depression. The results of this study suggest that escitalopram might exert its therapeutic effect in women in part through correction of a flattened diurnal cortisol rhythm.

AB - Phylogenetic networks generalise phylogenetic trees and allow for the accurate representation of the evolutionary history of a set of present-day species whose past includes reticulate events such as hybridisation and lateral gene transfer. One way to obtain such a network is by starting with a (rooted) phylogenetic tree T, called a base tree, and adding arcs between arcs of T. The class of phylogenetic networks that can be obtained in this way is called tree-based networks and includes the prominent classes of tree-child and reticulation visible networks. Initially defined for binary phylogenetic networks, tree-based networks naturally extend to arbitrary phylogenetic networks. In this paper, we generalise recent tree-based characterisations and associated proximity measures for binary phylogenetic networks to arbitrary phylogenetic networks. These characterisations are in terms of matchings in bipartite graphs, path partitions, and antichains. Some of the generalisations are straightforward to establish using the original approach, while others require a very different approach. Furthermore, for an arbitrary tree-based network N, we characterise the support trees of N, that is, the tree-based embeddings of N. We use this characterisation to give an explicit formula for the number of support trees of N when N is binary. This formula is written in terms of the components of a bipartite graph.

AB - PURPOSE: Moyamoya disease is a chronic cerebrovascular disorder characterized by progressive stenosis of the circle of Willis with a compensatory collateral vessel network. Recent studies have identified the ring finger protein 213 gene (RNF213) as the unique susceptibility gene for moyamoya disease. The purpose of this study was to compare clinical features of moyamoya disease, especially angiographic findings, between patients with and without the RNF213 mutation. METHODS: Blood samples from 35 patients with moyamoya disease were obtained between May 2016 and May 2017. Information on age at the time of diagnosis, sex, and initial symptom were obtained via retrospective chart review. Angiographic records were evaluated. RESULTS: RNF213 variants were detected in the 28 of 35 patients (80%), including all pediatric patients (100%) and 18 of 25 adult patients (72%) in our cohort. Leptomeningeal collateral flow from posterior to anterior circulation was more frequent in the RNF213-negative group than in the RNF213-positive group (100% versus 38.9%; p = 0.020). Posterior cerebral arterial territorial involvement was more frequently observed in RNF213-positive patients than in RNF213-negative patients (50% versus 0%; p = 0.027). CONCLUSIONS: RNF213 may play a significant role in the development of collateral anastomoses. PMID- 30283987 TI - Patterns of Superficial Midfacial Fat Volume Distribution Differ by Age and Body Mass Index. AB - BACKGROUND: The changes that occur to midfacial fat with increasing age and BMI are poorly understood. The aim of this study was to determine how superficial cheek fat volume and distribution are differentially predicted by changes in BMI versus age. METHODS: We conducted a retrospective observational study of patients with facial computed tomography scans. Superficial cheek fat volumes were measured, and multiple linear regression analysis was performed to model the relationships between cheek fat and corresponding sex, age, and BMI data. RESULTS: A total of 109 patients were included in our analysis (51 male, 58 female). The subjects' ages ranged from 21.7 to 91.1 years with a mean (SD) age of 59.7 (15.0) years. The mean (SD) superficial cheek volume of the subjects was 10.46 (2.57) cc. Female subjects had a significantly greater mean total superficial cheek fat volume compared to male subjects (11.18 cc vs. 9.64 cc; P < 0.001). The results of multiple linear regression analysis indicated that together, age, sex, and BMI explained 50.8% of the variance in cheek fat volumes (R2 = 0.51, P < 0.001). BMI significantly predicted total cheek fat volume (beta = 0.239, P < 0.001), in addition to age (beta = 0.029, P < 0.017) and sex (beta = - 1.183, P = 0.001; female = 0, male = 1). Age predicted the greatest gain of fat in the caudal subdivision of cheek (beta = 0.015, P < 0.001), whereas BMI predicted the greatest gain in the cephalad subdivision (beta = 0.106, P < 0.001). CONCLUSIONS: Age, sex, and BMI are important predictors of midfacial fat volume. This study shows that increases in age and BMI differentially predict the distribution of superficial cheek fat.

PMID- 30283988 TI - Lack of Association Between Vitamin D and Hand Grip Strength in Asians: A Nationwide Population-Based Study. AB - Despite the beneficial role and plausible mechanism of vitamin D on skeletal muscle in animal studies, its association in humans remains a controversial issue due to inconsistent clinical results, especially in older Asians. This was a population-based, cross-sectional study from the Korea National Health and Nutrition Examination Surveys, which enrolled 354 men aged >= 50 years and 328 postmenopausal women. Hand grip strength (HGS) was measured using a digital grip strength dynamometer. Low muscle strength was defined based on Korean-specific cut-off point of HGS. Serum 25-hydroxyvitamin D [25(OH)D] levels were 19.4 +/- 6.7 and 17.1 +/- 7.2 ng/mL in men and women, respectively. Among covariates including age, body mass index, lifestyle factors, and protein intake, age was inversely associated with HGS in both men and women, and protein intake (g/day) was positively associated with HGS only in men. However, the independent correlation between serum 25(OH)D and HGS was not observed, regardless of gender. When subjects were divided into three groups [deficient (25(OH)D < 20 ng/mL; 63.8%), insufficient (20 <= 25(OH)D < 30 ng/mL; 30.0%), or sufficient (25(OH)D >= 30 ng/mL; 6.2%)], there was no significant difference in HGS among these groups in both men and women. Consistently, serum 25(OH)D was not significantly different between subjects with and without low muscle strength, and there was no independent association of serum 25(OH)D with the risk of low muscle strength in both genders. These findings provide clinical evidence that protective role of vitamin D on human muscle metabolism may not be evident at least in older Asians. PMID- 30283989 TI - Regulation of the inositol transporter Itr1p by hydrogen peroxide in Saccharomyces cerevisiae. AB - Myo-inositol is a precursor of several membrane phospholipids and sphingolipids and plays a key role in gene regulation in Saccharomyces cerevisiae (S. cerevisiae). Here, we tested whether H2O2 was affecting the levels of the inositol transporters and thus inositol uptake. In S. cerevisiae cells adapted to H2O2 Itr1-GFPp accumulated in the plasma membrane until 20 min, concomitantly with an inhibition of its internalization. Exposure to H2O2 did not alter Itr2 GFPp cellular levels and induced only an 8% decrease at 10 min in the plasma membrane. Therefore, decreased inositol intracellular levels are not caused by decreased levels of inositol transporters in the plasma membrane. However, results show that H2O2 adaptation affects Itr1p turnover and, consequently, H2O2 adapted yeast cells display an inositol transporter phenotype comparable to cells grown in the absence of inositol in growth medium, i.e. accumulation in the plasma membrane and decreased degradation.

PMID- 30283991 TI - The Role of AcrAB-TolC Efflux Pumps on Quinolone Resistance of E. coli ST131. AB - Escherichia coli ST131 is a cause for global concern because of its high multidrug resistance and several virulence factors. In this study, the contribution of acrAB-TolC efflux system of E. coli ST131 to fluoroquinolone resistance was evaluated. A total of nonrepetitive 111 ciprofloxacin-resistant E. coli isolates were included in the study. Multilocus sequence typing was used for genotyping. Expressions of acrA, acrB, and TolC efflux pump genes were measured by RT-PCR. Mutations in marA, gyrA, parC, and aac(6')-lb-cr positivity were studied by Sanger sequencing. Sixty-four (57.7%) of the isolates were classified as ST131, and 52 (81.3%) of the ST131 isolates belonged to H30-Rx subclone. In ST131, CTX-M 15 positivity (73%) and aac(6')-lb-cr carriage (75%) were significantly higher than those in non-ST131 (12.8% and 51%, respectively) (P < 0.05). The ampicillin-sulbactam (83%) resistance was higher, and gentamicin resistance (20%) was lower in ST131 than that in non-ST131 (64% and 55%, respectively) (P = 0.001 and P = 0.0002). Numbers of the isolates with MDR or XDR profiles did not differ in both groups. Multiple in-dels (up to 16) were recorded in all quinolone-resistant isolates. However, marA gene was more overexpressed in ST131 compared to that in non-ST131 (median 5.98 vs. 3.99; P = 0.0007). Belonging to H30-Rx subclone, isolation site, ciprofloxacin MIC values did not correlate with efflux pump expressions. In conclusion, the marA regulatory gene of AcrAB TolC efflux pump system has a significant impact on quinolone resistance and progression to MDR profile in ST131 clone. Efflux pump inhibitors might be alternative drugs for the treatment of infections caused by E. coli ST131 if used synergistically in combination with antibiotics. PMID- 30283993 TI - Impact of Long-Term Application of Sewage on Soil and Crop Quality in Vertisols of Central India. AB - Shortfall of rain and the decreased groundwater level force farmers to use poor quality water for crop production in developing countries. In this study, the quality of agricultural produce and soil health affected by sewage water (Patranala) irrigation was evaluated. Sewage sediment, soil and crop samples were analyzed for physico-chemical properties. Sewage water found to contain trace concentration of heavy metals. However, long-term application of this water for crop production could build up a significant amount of trace metals in both soil and sediments. The DTPA extractable heavy metals ranged Cu 2.7-7.59, Cd 0.04 0.06, Pb 1.29-2.05, Cr 0.01-0.04, Ni 0.24-1.03 and Zn 0.63-2.59 mg kg-1 soil. The heavy metal risk assessment (hazard quotient, HQ) was calculated and found that HQ for these metals in the crops under study was in safe limits. From the study, it is concluded that growing vegetables using sewage water of Patranala is safe, but periodic monitoring to be carried out to avoid food chain contamination. PMID- 30283994 TI - Minimally invasive prostatic urethral lift (PUL) efficacious in TURP candidates: a multicenter German evaluation after 2 years. AB - INTRODUCTION: Successful outcomes have been reported for the treatment of lower urinary tract symptoms (LUTS) with the prostatic urethral lift (PUL) in a number of clinical investigations. Our aim was to investigate PUL outcomes in patients treated in a day-to-day clinical setting without the rigid exclusion criteria of clinical studies. MATERIALS AND METHODS: We investigated the outcome of the PUL procedure at five German departments during the initial period when PUL was approved for the clinic (10/2012-06/2014). All candidates for transurethral resection of the prostate (TURP) received PUL information and were given the choice of procedures. The only exclusion criterion was an obstructive median lobe. No patients were excluded because of high post-void residual volume (PVR), prostate size, retention history or LUTS oral therapy. Maximum urinary flow (Qmax), PVR, International Prostate Symptom Score (IPSS) and Quality of Life (QOL) were assessed at baseline, 1, 6, 12, and 24 months after surgery. RESULTS: Of 212 TURP candidates, 86 choose PUL. A mean of 3.8 (2-7) UroLift implants were implanted in patients of 38-85 years with a prostate size of 17-111 ml over 57 (42-90) min under general or local anesthesia. Thirty-eight (38.4%) patients had severe BPH obstruction and would have been denied PUL utilizing previously reported study criteria. Within 1 month 74 (86%) reported substantial symptom relief with significant improvements in Qmax, PVR, IPSS, and QOL (p < 0.001) that was maintained within the follow-up. Sexual function including ejaculation was unchanged or improved. No Clavien-Dindo Grad >= 2 was reported postoperatively. Eleven (12.8%) patients were retreated over 2 years. Twelve (86%) of 14 patients presenting with chronic urinary retention were catheter free at last follow-up. CONCLUSION: PUL is a promising surgical technique that may alleviate LUTS, even in patients with severe obstruction. PMID- 30283995 TI - Can urinary biomarkers replace cystoscopy? AB - PURPOSE: Diagnosis and follow-up in patients with non-muscle invasive bladder cancer (NMIBC) rely on cystoscopy and urine cytology. The aim of this review paper is to give an update on urinary biomarkers and their diagnosis and surveillance potential. Besides FDA-approved markers, recent approaches like DNA methylation assays, mRNA gene expression assays and cell-free DNA (cfDNA) are evaluated to assess whether replacing cystoscopy with urine markers is a potential scenario for the future. METHODS: We performed a non-systematic review of current literature without time period restriction using the National Library of Medicine database ( http://ww.pubmed.gov ). The search included the following key words in different combinations: "urothelial carcinoma", "urinary marker", "hematuria", "cytology" and "bladder cancer". Further, references were extracted from identified articles. The results were evaluated regarding their clinical relevance and study quality. RESULTS: Currently, replacing cystoscopy with available urine markers is not recommended by international guidelines. For FDA approved markers, prospective randomized trials are lacking. Newer approaches focusing on molecular, genomic and transcriptomic aberrations are promising with good accuracies. Furthermore, these assays may provide additional molecular information to guide individualized surveillance strategies and therapy. Currently ongoing prospective trials will determine if cystoscopy reduction is feasible. CONCLUSION: Urinary markers represent a non-invasive approach for molecular characterization of the disease. Although fully replacing cystoscopy seems unrealistic in the near future, enhancing the current gold standard by additional molecular information is feasible. A reliable classification and differentiation between aggressive and nonaggressive tumors by applying DNA, mRNA, and cfDNA assays may change surveillance to help reduce cystoscopies. PMID- 30283996 TI - Analysis of factors affecting re-admission after retrograde intrarenal surgery for renal stone. AB - PURPOSE: To investigate the factors associated with hospital readmission (HR) after retrograde intrarenal surgery (RIRS) among renal stone patients. METHODS: The study included patients who underwent RIRS from June 2011 to December 2017. Patients who were readmitted due to surgery-related complications were evaluated retrospectively. Patient demographics including age, medical comorbidity, body mass indices, ASA score, perioperative parameters and stone factors were compared with total cohorts. HR was defined as visits to the Emergency Room or unplanned admission within 30 days after discharge. The factors affecting HR rates were analyzed using uni- and multi-variate analyses. RESULTS: A total of 572 patients were enrolled into the study. The mean age was 57.6 +/- 14.1 years and the mean stone diameter was 13.4 +/- 6.2 mm. The mean complication rate was 6.1% and the median hospitalization time was 2.1 +/- 3.4 days. HR occurred in 20 patients (3.5%). Compared to non-admission patients, readmitted patients had a higher rate of bilateral RIRS (20.0% vs 12.2%, p = 0.035), number of stones (4.65 vs 2.2, p = 0.041) and higher stone complexity score (4.15 vs 2.11, p = 0.003). Multivariate analysis showed bilateral RIRS (OR 1.091, p = 0.031) and stone complexity (OR 1.405, p = 0.003) were significant factors to predict re-admission after RIRS. CONCLUSION: Patients with complex renal stones or those who underwent bilateral RIRS were more likely to have a higher rate of re-admission. Proper perioperative management to prevent complications should be planned based on these predictive factors. PMID- 30283997 TI - A signal-on electrochemiluminescence sensor for clenbuterol detection based on zinc-based metal-organic framework-reduced graphene oxide-CdTe quantum dot hybrids. AB - Clenbuterol (CLB) is harmful to human health when used long term, and it has been listed by the World Anti-Doping Agency (WADA). In this work, a novel zinc-based metal-organic frameworks-reduced graphene oxide-CdTe quantum dots (ZnMOF-RGO-CdTe QDs) hybrid was used to construct an electrochemiluminescence (ECL) sensor for detecting CLB. CdTe QDs, loaded by RGO, exhibited an enhanced ECL signal. In addition, the ZnMOFs catalyzed OH* generation by coreactant H2O2, which further strengthened the ECL signal of the CdTe QDs. The integration of ZnMOFs and RGO CdTe QDs endowed the sensor with high sensitivity for CLB detection. The intensity of the ECL signal increased as the concentration of CLB increased. The linear range of CLB detection was 3.0 * 10-13 M to 6.0 * 10-10 M, and the detection limit was estimated to be 1.0 * 10-13 M. Furthermore, the sensor displayed a good repeatability and stability. The ZnMOF-RGO-CdTe QD hybrids described in this study provide a foundation for the development of new methods of detecting CLB. Graphical abstract ?. PMID- 30283998 TI - Non-invasive monitoring of blood glucose using optical methods for skin spectroscopy-opportunities and recent advances. AB - Diabetes mellitus is a widespread disease with greatly rising patient numbers expected in the future, not only for industrialized countries but also for regions in the developing world. There is a need for efficient therapy, which can be via self-monitoring of blood glucose levels to provide tight glycemic control for reducing the risks of severe health complications. Advancements in diabetes technology can nowadays offer different sensor approaches, even for continuous blood glucose monitoring. Non-invasive blood glucose assays have been promised for many years and various vibrational spectroscopy-based methods of the skin are candidates for achieving this goal. Due to the small spectral signatures of the glucose hidden among a largely variable background, the largest signal-to-noise ratios and multivariate calibration are essential to provide the method applicability for self-monitoring of blood glucose. Besides multiparameter approaches, recently presented devices based on photoplethysmography with wavelengths in the visible and near-infrared range are evaluated for their potential of providing reliable blood glucose concentration predictions. Graphical abstract ?. PMID- 30283999 TI - Photoelectrochemical immunoassay of lipoprotein-associated phospholipase A2 via plasmon-enhanced energy transfer between gold nanoparticles and CdS QDs/g-C3N4. AB - A facile and feasible photoelectrochemical (PEC) immunoassay based on plasmon enhanced energy transfer between gold nanoparticles (AuNPs) and CdS quantum dots (QDs)/g-C3N4 nanosheets was developed for the ultrasensitive detection of lipoprotein-associated phospholipase A2 (Lp-PLA2). To construct such a sensing platform, the immunosensor was prepared by immobilizing Lp-PLA2 on a CdS QDs/g C3N4-modified electrode. A competitive-type immunoreaction was utilized for Lp PLA2 detection, with AuNP-labeled anti-Lp-PLA2 antibody used as the competitor. Introducing AuNPs with the specific antibody for the antigen target Lp-PLA2 led to heavy quenching of the photocurrent of CdS QDs/g-C3N4 due to the plasmon enhanced energy transfer between AuNPs and CdS QDs. The quenching efficiency decreased with increasing target Lp-PLA2 concentration. Under optimal conditions, the PEC immunosensor presented a good photocurrent response to the target Lp-PLA2 in the dynamic linear range of 0.01-300 ng mL-1, with a low detection limit of 5.3 pg mL-1. Other biomarkers and natural enzymes did not interfere with response of this system. The reproducibility and accuracy of this method for the analysis of human serum specimens were evaluated, and the results given by the method developed here were found to closely correspond to the results obtained with commercial Lp-PLA2 ELISA kits. Importantly, this protocol offers promise for the development of exciton-plasmon interaction-based PEC detection systems. Graphical abstract ?. PMID- 30284000 TI - Selective extraction of 3,4-dihydroxybenzoic acid in Ilex chinensis Sims by meticulous mini-solid-phase microextraction using ternary deep eutectic solvent based molecularly imprinted polymers. AB - A ternary deep eutectic solvent (TDES) was used as both template and functional monomer in the synthesis of TDES-based molecularly imprinted polymers (TDES MIPs). A meticulous miniaturized solid-phase microextraction (mini-SPME) method followed by high-performance liquid chromatography (HPLC) were used for the optimal speciation of 3,4-dihydroxybenzoic acid (3,4-DHBA) in the needle of a syringe system with response surface methodology (RSM). Under the optimal conditions for the determination of 3,4-DHBA (amount of adsorbent (2 mg), sample volume (1 mL), cycles for adsorption and desorption (6)), the actual extraction amount was 8.46 MUg g-1. The limits of detection (LODs, S/N = 3) for 3,4-DHBA in Ilex chinensis Sims were 0.26-0.31 MUg mL-1, and the intra-day and inter-day precision (relative standard deviations, n = 4) after spiking with 5 MUg mL-1, 100 MUg mL-1, and 200 MUg mL-1 were both less than 4.21%. The meticulous method (TDES-MIP-mini-SPME) combined with RSM offers a significant advance over existing methods, because of the meticulous operation and excellent selectivity of 3,4 DHBA from complex samples. Graphical abstract ?. PMID- 30284001 TI - Os acetabuli and femoro-acetabular impingement: aetiology, incidence, treatment, and results. AB - PURPOSE: The purpose of this study was to investigate the pathogenesis, the incidence, and the results of arthroscopic treatment of os acetabuli (OSA) in a group of patients with diagnosis of femoro-acetabular impingement (FAI). METHODS: We retrospectively analyzed the full documentation of 294 hips in 273 patients (21 bilateral) operated for FAI through hip arthroscopy. We reviewed all radiographs and arthro-MRI in order to identify the incidence of OSA. All patients with OSA were then assessed with a modified Harris hip score (MHHS) pre operatively and at the final follow-up. RESULTS: Twenty-one patients (7.7%), 20 (95%) of them were male, were diagnosed with concomitant FAI and os acetabuli. In 21 cases, OSA was excised and FAI was treated with rim trimming, femoral osteoplasty, or both. In one case, a large OSA fragment was fixed with a 4 mm screw avoiding an acetabular uncoverage if excised. The average follow-up was 31 months (range from 6 to 69 months). The MHHS showed an improvement from a pre operative MHHS of 57.5 (range from 39 to 82) to 95 (range from 73 to 100). CONCLUSIONS: Os acetabuli is not uncommon and certainly associated with FAI and male gender. The etiology is probably microtraumatic. The arthroscopic OSA removal or fixation and concomitant FAI treatment showed very good results. Interestingly, these outcomes seem better than FAI treatment alone. Further studies with a wider number of patients and a longer follow-up are needed to confirm these results and understand the real role of OSA in this setting. PMID- 30284002 TI - Bone mineral density as a marker of hip implant longevity: a prospective assessment of a cementless stem with dual-energy X-ray absorptiometry at twenty years. AB - PURPOSE: Bone remodeling around the femoral component after total hip arthroplasty (THA) is considered to be an important factor in long-term stability and seems to be strictly related to the stem design, coating, and fixation. Stress shielding, micro-movement, and high intra-articular fluid pressure might activate macrophages and osteoclasts, causing progressive bone density decreases. Here we analyze the bone mineral density (BMD) around a cementless femoral stem during a 20-year period to better understand the adaptive bone changes around such implants during long-term follow-up. METHODS: In this retrospective study, 14 patients treated by THA were reviewed from a cohort of 84. Clinical evaluation with Harris Hip Score and radiographic assessment were performed throughout a 20 year follow-up. To evaluate the bone remodeling around the stem, we monitored the femoral BMD in four regions of interest with a dual-energy X-ray absorptiometry (DEXA) post-operatively and at one, two, three, five and 20 years of follow-up. RESULTS: The main BMD changes between the post-operative examination and the 20 year follow-up varied between + 11.19% and + 24.30%. Patients with signs of loosening, low Harris Hip Scores, and pain showed decreasing BMD values. CONCLUSIONS: The correlation between the clinical result and BMD values could suggest DEXA results as a predictor of implant loosening or longevity. PMID- 30284003 TI - Primary cementless total knee arthroplasty with or without stem extension: a matched comparative study of ninety eight standard stems versus ninety eight long stems after more than ten years of follow-up. AB - INTRODUCTION: Using a cementless fixation for total knee arthroplasty (TKA) is controversial. We hypothesized that cementless tibial base plate with a monoblock long stem (MLS) would provide secure tibial alignment and stable fixation when bone conditions were considered as poor for a cementless fixation. The purpose of this study was to compare the mean eight year survivorship of cementless standard keels (SK) vs cementless MLS. MATERIAL METHODS: We report a matched series of 98 cases of SK and 98 cases of MLS in patients with poor bone conditions. The two cohorts were statistically compared. Revision for tibial loosening was used as the endpoint in the survivorship analysis. RESULTS: We recorded two cases of tibial loosening and three cases of bipolar loosening in the SK group (0% MLS vs 5% SK). No tibial loosening occurred in the MLS group (statistically significant). No tibial periprosthetic or intra-operative fractures occurred in either group. The survivorship at eight years of follow-up was 95.6% in the SS cohort vs 100% in the MLS cohort using revision for tibial loosening as the endpoint. DISCUSSION: This study was not randomized. Its strength was that it took into account the comparative midterm outcomes of a matched cohort of patients implanted with two types of cementless components in the same bone conditions. We did not record any tibial loosening in the MLS group. Using long stems has been criticized but we did not observe any adverse reactions and no intra-operative tibial fracture occurred. CONCLUSION: MLS improves the alignment and fixation of cementless TKA. This is a safe solution when bone conditions are poor or modified by previous surgery. PMID- 30284004 TI - Arthroscopic synovectomy of the knee joint for rheumatoid arthritis. AB - OBJECTIVE: To investigate the effect of knee arthroscopic synovectomy (AS) on the disease activity, quality-of-life (QoL), and the functional status of patients with rheumatoid arthritis (RA). MATERIALS AND METHODS: A retrospective analysis was conducted on the outcomes of AS performed on 138 RA patients; pre-surgery assessments were done using Disease Activity score (DAS 28) and Routine Assessment of Patient Index Data ZE (RAPID-3) on a multidimensional health assessment questionnaire for disease activity, EuroQol-5D (EQ-5D) and the Short Form Medical Outcomes Study (SF-36) for quality of life, and the Health Assessment Questionnaire (HAQ) for functional status. The pain response to SA was measured by a visual analogue score (VAS) and the Knee Society Score (KSS). RESULTS: All parameters assessed in the study showed significant positive changes: the activity of the disease decreased, and patients' functional status and QoL improved. CONCLUSION: AS is effective treatment for recurrent synovitis of the knee in RA patients. This technique improves the functional status of patients and their quality of life and reduces the activity of the disease.

AB - Perinatal hypophosphatasia (HPP) is a rare, potentially life-threatening, inherited, systemic metabolic bone disease that can be difficult to recognize in utero and postnatally. Diagnosis is challenging because of the large number of skeletal dysplasias with overlapping clinical features. This review focuses on the role of fetal and neonatal imaging modalities in the differential diagnosis of perinatal HPP from other skeletal dysplasias (e.g., osteogenesis imperfecta, campomelic dysplasia, achondrogenesis subtypes, hypochondrogenesis, cleidocranial dysplasia). Perinatal HPP is associated with a broad spectrum of imaging findings that are characteristic of but do not occur in all cases of HPP and are not unique to HPP, such as shortening, bowing and angulation of the long bones, and slender, poorly ossified ribs and metaphyseal lucencies. Conversely, absent ossification of whole bones is characteristic of severe lethal HPP and is associated with very few other conditions. Certain features may help distinguish HPP from other skeletal dysplasias, such as sites of angulation of long bones, patterns of hypomineralization, and metaphyseal characteristics. In utero recognition of HPP allows for the assembly and preparation of a multidisciplinary care team before delivery and provides additional time to devise treatment strategies.

AB - BACKGROUND: Knowing that ureteropelvic junction obstruction is due to a crossing renal vessel is essential in choosing the appropriate surgical treatment. OBJECTIVE: To evaluate the diagnostic accuracy of non-contrast magnetic resonance (MR) angiography in identifying crossing renal vessels in children younger than 4 years old with unilateral hydronephrosis. MATERIALS AND METHODS: A retrospective review of preoperative MR urography of children with unilateral hydronephrosis was conducted by two independent readers. The presence or absence of crossing renal vessels was identified and compared with surgical findings. RESULTS: Twenty nine patients were included. The disagreement between MR angiography with and without contrast enhancement in detecting a crossing renal vessel was 8%. The disagreement between non-contrast-enhanced MR and surgical findings was 17%. The disagreement between contrast-enhanced MR angiography and surgical findings was 25%. The balanced triggered angiography without contrast enhancement had a sensitivity of 70% (95% confidence interval [CI]: 35-93%) and a specificity of 93% (95% CI: 66-100%). Contrast-enhanced MR angiography had a sensitivity of 56% (95% CI: 21-86%) and a specificity of 91%. (95% CI: 59-100%). CONCLUSION: MR without contrast enhancement may be a reliable, valid and safe alternative to contrast-enhanced MR angiography for identifying crossing renal vessels.

It is known that rotator cuff tendinopathy contributes to osteoarthritis (OA) of the shoulder. The aim of the study was to analyse the presence of tendinopathy in patients with shoulder OA and an intact rotator cuff, using a multimodal approach. METHODS: Thirteen consecutive patients median age 67 (52-84) years, with OA of the shoulder, and 13 consecutive control patients, with a fracture of the proximal humerus, median age 70 (51-84) years, underwent an open biopsy procedure from the biceps and subscapularis tendon in conjunction with shoulder arthroplasty. In addition to a macroscopic evaluation, the samples underwent histologic, morphologic and ultrastructural analyses in light and transmission electron microscopy. RESULTS: Macroscopic degeneration was found in 15 of 26 specimen in the OA group but in seven of 25 in the control group (p = 0.048). The histologic analysis revealed a non-significant difference for the total degeneration score (TDS) between the study groups. The morphologic evaluation of the samples revealed that the OA group had significantly more samples with non homogeneous extracellular matrix (ECM), (p = 0.048). Ultrastructurally, the OA group revealed a significantly larger fibril diameter in the biceps tendon (p < 0.0001) but not in the subscapularis tendon compared with the control group. CONCLUSION: A significantly worse macroscopic appearance and significantly more morphologically inhomogeneous ECM, indicating more tendon degeneration, were found in the OA group compared with the control group. This indicates that it could be beneficial to treat the tendinosis in an early stage to decrease symptoms from the OA. STUDY DESIGN: Level of evidence, III. PMID- 30284008 TI - Degenerative isolated cartilage defects of the patellofemoral joint are associated with more severe symptoms compared to trauma-related defects: results of the German Cartilage Registry (KnorpelRegister DGOU). AB - PURPOSE: The purpose of this study was to utilize data from the German Cartilage Registry (KnorpelRegister DGOU) to examine the hypothesis that degenerative cartilage defects of the patellofemoral joint are associated with more severe clinical symptoms compared to trauma-related defects. METHODS: All patients with isolated focal cartilage defects of the patellofemoral joint registered in the German Cartilage Registry until May 2017 were included in the study. Patients with previous surgery of the ipsilateral knee were excluded. Baseline data including etiology (traumatic, degenerative), size, location and ICRS grade of the cartilage defects as well as the duration of symptoms were analyzed. Clinical symptoms were evaluated by means of the numeric analog scale (NAS) for pain and the Knee injury and Osteoarthritis Outcome Score (KOOS). Group comparisons were performed using the Mann-Whitney-U test along with the Chi-squared test and Fisher's exact test. A bivariate correlation analysis and a multivariable linear regression analysis were performed to investigate the association between the defect characteristics and the clinical scores. RESULTS: A total of 423 patients (203 traumatic and 220 degenerative defects) were included. Isolated degenerative cartilage defects were found to have significantly more trochlear locations (28% vs. 18%; p = 0.006), significantly less ICRS grade 4 lesions (50% vs. 73%; p = 0.002) and a significantly smaller defect size [median 300 (IQR 105-400) vs. 300 (200-400) mm2] when compared to those from traumatic etiology. Traumatic defects showed significantly better KOOS-ADL [77 (60-90) vs. 69 (56-82); p = 0.005], KOOS pain [69 (56-81) vs. 61 (47-75); p = 0.001] and NAS [2 (1-5) vs. 4 (1-6); p = 0.005] scores compared to degenerative defects. The correlation analysis revealed only weak correlations between the quantitative defect characteristics and clinical scores. CONCLUSIONS: Degenerative isolated cartilage defects in the patellofemoral joint are associated with more severe clinical symptoms in comparison to trauma-related defects. Additionally, they show a larger variance regarding their location with more trochlear defects. LEVEL OF EVIDENCE: III. PMID- 30284009 TI - Two-dimensional measurement misidentifies alignment outliers in total knee arthroplasty: a comparison of two- and three-dimensional measurements. AB - PURPOSE: Two-dimensional (2D) and three-dimensional (3D) measurements of prosthetic alignment and "outliers" after total knee arthroplasty (TKA) might not necessarily be comparable. The aim of this study was to compare the use of 2D and 3D measurements in the identification of prosthetic alignment and outliers after TKA. METHODS: This cross-sectional study included 159 consecutive TKAs. All patients underwent plain radiography, fluoroscopy-guided radiography, and computed tomography after TKA. The same baseline was used for 2D and 3D measurements. The reliability of prosthetic alignment and outlier identification (> 3 degrees from neutral alignment) was compared between the 2D and 3D measurements. RESULTS: The mean prosthetic alignment and rate of outliers were not significantly different the between 2D and 3D measurements. The inter- and intra-observer reliabilities were higher for the 3D measurements than for the 2D measurements. The agreement between 2D and 3D measurements in outlier identification was poor, except for femoral coronal alignment. Cohen's kappa coefficients were 0.19 in femoral sagittal (poor), 0.02 in tibial coronal (poor), and 0.10 in tibial sagittal (poor) on plain radiography. The values were 0.23 in tibial coronal (poor) and 0.002 in tibial sagittal (poor) on fluoroscopy-guided radiography. CONCLUSIONS: The agreement between 2D and 3D measurements in the identification of outliers was poor, even on fluoroscopy-guided radiography. Since 2D measurements have an inherent risk of misidentifying alignment outliers, this finding is clinically relevant. To properly analyze the correlation between outliers and clinical results, such as longevity, patient satisfaction, and patient-reported outcome, 3D measurements for prosthetic alignment are desirable.

AB - PURPOSE: Only few studies have investigated medial epicondyle (MEC) lesions, particularly in the 12-18 age group. To the best of our knowledge, no study has compared ultrasonography (US), radiography and magnetic resonance imaging (MRI) in detecting MEC lesions. The aims of this study were to examine the value of US for detecting MEC lesions and to investigate correlations among diagnostic tools. METHODS: A prospective, comparative study was performed. Young baseball players from southern Taiwan were recruited, and basic characteristics, as well as passive range of motion (pROM) of the upper extremities, were recorded. Screening US was performed to identify MEC lesions, and players with MEC lesions received follow-up plain radiography and MRI. RESULTS: A total of 299 young baseball players were screened using US, and 28 of 299 players with possible MEC lesions were identified with a positive predictive value (PPV) of 88% according to MRI findings. The MEC lesions were primarily comprised of unfused ossicles and bony fragmentation. Other diagnoses, including UCL strain and medial epicondylitis, were also found by MRI in players with abnormal US screening results. The pROM of shoulder external rotation (ER) of the throwing hand was significantly reduced in players with MEC lesions (p = 0.006). CONCLUSIONS: Bony cortical discontinuity or fragmentation over the MEC warrants further research, and US provides good PPV for types of MEC lesions. Decreased shoulder ER may relate to MEC lesions and should be taken into consideration. The use of US may facilitate early detection and intervention. LEVEL OF EVIDENCE: IV, Cross-sectional study. PMID- 30284011 TI - Bioconversion of green volatiles in okara (soybean residue) into esters by coupling enzyme catalysis and yeast (Lindnera saturnus) fermentation. AB - Okara (soybean residue), a by-product from soymilk and tofu production, has a green, grassy off odour as it contains a large amount of aldehydes. This work investigated the rate-limiting enzyme(s) in the formation of aldehydes in okara and the pathways leading to their bioconversion into fruity, pleasant-smelling esters by the yeast Lindnera saturnus. Lipase and hydroperoxide lyase were shown to be rate-limiting enzymes while endogenous soy lipoxygenase was also crucial for the production of aldehydes in okara. Subsequent fermentation of okara by L. saturnus increased the amount of esters by about 70 times to 165-277 MUg/g dried okara. The generation of C7 esters followed our hypothesised pathway, while that for C6 esters was mainly affected by L. saturnus. This study presents a simple and inexpensive one-pot setup for the natural bio-production of esters from okara. PMID- 30284012 TI - Analysis of differentially upregulated proteins in ptsHIcrr- and rppH- mutants in Escherichia coli during an adaptive laboratory evolution experiment. AB - The previous deletion of the cytoplasmic components of the phosphotransferase system (PTS) in Escherichia coli JM101 resulted in the PTS- derivative strain PB11 with severely impaired growth capability in glucose as the sole carbon source. Previous adaptive laboratory evolution (ALE) experiment led to select a fast-growing strain named PB12 from PB11. Comparative genome analysis of PB12 showed a chromosomal deletion, which result in the loss of several genes including rppH which codes for the RNA pyrophosphohydrolase RppH, involved in the preparation of hundreds of mRNAs for further degradation by RNase E. Previous inactivation of rppH in PB11 (PB11rppH-) improved significantly its growing capabilities and increased several mRNAs respect its parental strain PB11. These previous results led to propose to the PB11rppH- mutant as an intermediate between PB11 and PB12 strains merged during the early ALE experiment. In this contribution, we report the metabolic response to the PTS- and rppH- mutations in the deep of a proteomic approach to understanding the relevance of rppH- phenotype during an ALE experiment. Differentially upregulated proteins between the wild-type JM101/PB11, PB11/PB11rppH-, and PB11/PB12 comparisons led to identifying 45 proteins between strain comparisons. Downregulated or upregulated proteins in PB11rppH- were found expressed at an intermediate level with respect to PB11 and PB12. Many of these proteins were found involved in non-previously metabolic traits reported in the study of the PTS- strains, including glucose, amino acids, ribose transport; amino acid biosynthesis; NAD biosynthesis/salvage pathway, biosynthesis of Ac-CoA precursors; detoxification and degradation pathways; stress response; protein synthesis; and possible mutator activities between comparisons. No changes were found in the expression of galactose permease GalP, previously proposed as the primary glucose transporter in the absence of PTS selected by the PTS- derivatives during the ALE experiment. This result suggests that the evolving PTS- population selected other transporters such as LamB, MglB, and ManX instead of GalP for glucose uptake during the early ALE experiment. Analysis of the biological relevance of the metabolic traits developed by the studied strains provided valuable information to understand the relevance of the rppH- mutation in the PTS- background during an ALE experiment as a strategy for the selection of valuable phenotypes for metabolic engineering purposes. PMID- 30284013 TI - 2-Deoxy-D-ribose-5-phosphate aldolase (DERA): applications and modifications. AB - 2-Deoxy-D-ribose-5-phosphate aldolase (DERA) is a class I aldolase that offers access to several building blocks for organic synthesis. It catalyzes the stereoselective C-C bond formation between acetaldehyde and numerous other aldehydes. However, the practical application of DERA as a biocatalyst is limited by its poor tolerance towards industrially relevant concentrations of aldehydes, in particular acetaldehyde. Therefore, the development of proper experimental conditions, including protein engineering and/or immobilization on appropriate supports, is required. The present review is aimed to provide a brief overview of DERA, its history, and progress made in understanding the functioning of the enzyme. Furthermore, the current understanding regarding aldehyde resistance of DERA and the various optimizations carried out to modify this property are discussed. PMID- 30284014 TI - Genome-wide profiling of histone H3K27 acetylation featured fatty acid signalling in pancreatic beta cells in diet-induced obesity in mice. AB - AIMS/HYPOTHESIS: Epigenetic regulation of gene expression has been implicated in the pathogenesis of obesity and type 2 diabetes. However, detailed information, such as key transcription factors in pancreatic beta cells that mediate environmental effects, is not yet available. METHODS: To analyse genome-wide cis regulatory profiles and transcriptome of pancreatic islets derived from a diet induced obesity (DIO) mouse model, we conducted chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-Seq) of histone H3 lysine 27 acetylation (histone H3K27ac) and high-throughput RNA sequencing. Transcription factor-binding motifs enriched in differential H3K27ac regions were examined by de novo motif analysis. For the predicted transcription factors, loss of function experiments were performed by transfecting specific siRNA in INS-1, a rat beta cell line, with and without palmitate treatment. Epigenomic and transcriptional changes of possible target genes were evaluated by ChIP and quantitative RT-PCR. RESULTS: After long-term feeding with a high-fat diet, C57BL/6J mice were obese and mildly glucose intolerant. Among 39,350 islet cis-regulatory regions, 13,369 and 4610 elements showed increase and decrease in ChIP-Seq signals, respectively, significantly associated with global change in gene expression. Remarkably, increased H3K27ac showed a distinctive genomic localisation, mainly in the proximal-promoter regions, revealing enriched elements for nuclear respiratory factor 1 (NRF1), GA repeat binding protein alpha (GABPA) and myocyte enhancer factor 2A (MEF2A) by de novo motif analysis, whereas decreased H3K27ac was enriched for v-maf musculoaponeurotic fibrosarcoma oncogene family protein K (MAFK), a known negative regulator of beta cells. By siRNA-mediated knockdown of NRF1, GABPA or MEF2A we found that INS-1 cells exhibited downregulation of fatty acid beta-oxidation genes in parallel with decrease in the associated H3K27ac. Furthermore, in line with the epigenome in DIO mice, palmitate treatment caused increase in H3K27ac and induction of beta-oxidation genes; these responses were blunted when NRF1, GABPA or MEF2A were suppressed. CONCLUSIONS/INTERPRETATION: These results suggest novel roles for DNA-binding proteins and fatty acid signalling in obesity-induced epigenomic regulation of beta cell function.

PMID- 30284015 TI - Clinical outcomes of an integrated primary-secondary model of care for individuals with complex type 2 diabetes: a non-inferiority randomised controlled trial. AB - AIMS/HYPOTHESIS: The aim of the study was to determine if a Beacon model of integrated care utilising general practitioners (GPs) with special interests could achieve similar clinical outcomes to a hospital-based specialist diabetes outpatient clinic. METHODS: This pragmatic non-inferiority multisite randomised controlled trial assigned individuals with complex type 2 diabetes to care delivered by a Beacon clinic or to usual care delivered by a hospital outpatient department, in a 3:1 ratio. Owing to the nature of the study, researchers were only blinded during the allocation process. Eligible participants were aged 18 or over, had been referred by their usual GP to the hospital central referral hub with type 2 diabetes and had been triaged to be seen within 30 or 90 days. The intervention consisted of diabetes management in primary care by GPs with a special interest who had been upskilled in complex diabetes under the supervision of an endocrinologist. The primary outcome was HbA1c at 12 months post recruitment. The non-inferiority margin was 4.4 mmol/mol (0.4%). Both per protocol and intention-to-treat analyses are reported. RESULTS: Between 27 November 2012 and 14 July 2015, 352 individuals were recruited and 305 comprised the intention-to-treat sample (71 in usual care group and 234 in the Beacon model group). The Beacon model was non-inferior to usual care for both the per-protocol (difference -0.38 mmol/mol [95% CI -4.72, 3.96]; -0.03% [95% CI -0.43, 0.36]) and the intention-to-treat (difference -1.28 mmol/mol [95% CI -5.96, 3.40]; -0.12% [95% CI -0.55, 0.31]) analyses. Non-inferiority was sustained in a sensitivity analysis at 12 months. There were no statistically or clinically significant differences in the secondary outcomes of BP, lipids or quality of life as measured by the 12 item short-form health survey (SF-12v2) and the diabetes related quality of life (DQoL-Brief) survey. Safety indicators did not differ between groups. Participant satisfaction on the eight-item client satisfaction questionnaire (CSQ-8) was good in both groups, but scores were significantly higher in the Beacon model group than the usual care group (mean [SD] 28.4 [4.9] vs 25.6 [4.9], respectively, p < 0.001). CONCLUSIONS/INTERPRETATION: In individuals with type 2 diabetes, a model of integrated care delivered in the community by GPs with a special interest can safely achieve clinical outcomes that are not inferior to those achieved with gold-standard hospital-based specialist outpatient clinics. Individuals receiving care in the community had greater satisfaction. Further studies will determine the cost of delivering this model of care.

PMID- 30284016 TI - Detection and quantification of beta cells by PET imaging: why clinical implementation has never been closer. AB - In this issue of Diabetologia, Alavi and Werner ( https://doi.org/10.1007/s00125 018-4676-1 ) criticise the attempts to use positron emission tomography (PET) for in vivo imaging of pancreatic beta cells, which they consider as 'futile'. In support of this strong statement, they point out the limitations of PET imaging, which they believe render beta cell mass impossible to estimate using this method. In our view, the Alavi and Werner presentation of the technical limitations of PET imaging does not reflect the current state of the art, which leads them to questionable conclusions towards the feasibility of beta cell imaging using this approach. Here, we put forward arguments in favour of continuing the development of innovative technologies enabling in vivo imaging of pancreatic beta cells and concisely present the current state of the art regarding putative technical limitations of PET imaging. Indeed, far from being a 'futile' effort, we demonstrate that beta cell imaging is now closer than ever to becoming a long-awaited clinical reality. PMID- 30284017 TI - The perfusion index is a useful screening tool for peripheral artery disease. AB - The number of people with peripheral artery disease (PAD) has been increasing globally; therefore, it is important to explore more options to screen patients who are at a risk of developing PAD. The perfusion index (PI) represents the degree of circulation through the peripheral tissues and is measured noninvasively. We investigated the correlation between the PI and ankle-brachial index (ABI) to explore whether the PI could be used a screening tool for PAD. This cross-sectional study included 390 patients. We measured the ABI and PI for all patients. The median ABI value was 1.06 (0.92-1.13); the PI was 1.7% (0.9 3.5). The PI was higher in men than in women (P < 0.0001). The PI was positively correlated with the estimated glomerular filtration rate and ABI in both men and women. The sensitivity and specificity of the PI to predict PAD (ABI <=0.9) were 90.0% and 80.3%, respectively, and the cutoff PI value was 1.5% in men. The sensitivity and specificity of the PI to predict PAD were 82.1% and 79.2%, respectively, and the cutoff PI value was 1.1% in women. PI could be a reliable screening tool for diagnosing PAD because it does not restrict the patient's mobility, can be completed in a short time period, and is associated with reduced costs. PMID- 30284018 TI - Differential effect of concomitant antidiabetic agents on carotid atherosclerosis: a subgroup analysis of the PROLOGUE study. AB - Accumulated evidence shows that some antidiabetic agents attenuate the progression of carotid atherosclerosis assessed as intima-media thickness (IMT). Although some studies have demonstrated an inhibitory effect of dipeptidyl peptidase-4 inhibitors on carotid IMT progression, in the PROLOGUE study sitagliptin failed to slow progression relative to conventional therapy for 24 months. We hypothesized that differences in the concomitant antidiabetic agents between the groups have influenced the progression of carotid IMT. We performed a post hoc analysis of the PROLOGUE study using subgroups stratified by concomitant antidiabetic agents. Although no subgroup with any combination of agents in the overall patients showed a significant difference between sitagliptin group and conventional therapy group in the changes from baseline in mean common carotid artery (CCA)-IMT at 24 months, a significant attenuation of mean CCA-IMT progression was observed in the sitagliptin group relative to conventional therapy group only in three combination subgroups aged < 70 years, namely no thiazolidinedione; no thiazolidinedione or biguanide; and no thiazolidinedione, biguanide or alpha-glucosidase inhibitor, even after adjustment for multiple confounding factors. In the three subgroups, no significant difference between sitagliptin group and conventional therapy group in the changes from baseline in HbA1c at 24 months was detected. Our data suggest that some concomitant agents, whose prescription frequencies were increased in the conventional therapy group, may have masked the inhibitory effect of sitagliptin on carotid IMT progression in the PROLOGUE study.

AB - Coil migration following cerebral aneurysm treatment has been described and may result in stroke, recurrent aneurysm, or local mass effect. Cerebral coil embolization is also applied in arteriovenous malformations and arteriovenous fistulas, but these pathologies are relatively rare and coil migration is not as well described. Furthermore, these cases are more commonly treated with combinations of multiple modalities to achieve cure. Embolization, surgery, and radiation each have risks and benefits and combinations may have synergistic risks and benefits not seen in monotherapy. We report a case of extravascular and extra-corporeal coil migration after embolization and craniectomy to treat a patient with hemorrhage from an arteriovenous fistula.

PMID- 30284022 TI - A novel liver retraction method in laparoscopic gastrectomy for gastric cancer. AB - BACKGROUND: Retracting the lateral liver segment during laparoscopic distal gastrectomy is important for achieving an optimal surgical field. However, excessive force may injure the liver, causing temporary abnormalities of liver function tests after laparoscopic surgery. We developed a new liver retraction method and assessed its safety and utility. PATIENTS AND METHODS: We retrospectively analyzed records in our surgical database of consecutive surgical patients who underwent laparoscopic distal gastrectomy for early gastric cancer. We divided the 229 patients into two groups based on the liver retraction method used, either flexible liver retraction with clipping and suturing (FLICS) or the Nathanson retractor (NR). One-to-one propensity score matching was performed to match patients, resulting in the records of 53 pairs of cases extracted from the database. Operative and postoperative outcomes were assessed, including following the values of serum liver enzymes, total bilirubin, and C-reactive protein until postoperative day 30. RESULTS: There were no significant differences in patient characteristics or preoperative data in the two groups. The retraction method was not changed intraoperatively for any patients. The operative time was significantly shorter in the FLICS group, but the amount of bleeding did not differ. Liver injury was not observed as a result of liver retraction during surgery. In both groups, serum liver enzymes temporarily increased after surgery but improved rapidly thereafter. The postoperative increases in aspartate transaminase, alanine transaminase, and C-reactive protein levels were significantly lower in the FLICS than in the NR group. No serious complications associated with liver retraction were observed in either group. CONCLUSIONS: Our new liver retraction technique provided an optimal surgical field without inducing liver dysfunction. It is a simple, safe, and effective liver retraction technique. PMID- 30284024 TI - Inherited cardiomyopathies in veterinary medicine. AB - Comparative and translation medicine is of particular value within the field of inherited cardiomyopathies. Despite massive advances in understanding the functional role of mutations in human cardiomyopathies, these advances have frequently failed to translate into medical discoveries that alter patient care. One potential explanation for this failure lies in the lack of suitable translational models that adequately recapitulate human cardiovascular physiology and disease expression. The vast genetic heterogeneity that complicates human cardiomyopathy research is potentially alleviated through the study of naturally occurring large animal models of disease, where incredibly homogenous populations, like those seen in a single breed of dog or cat, may exist (Kol et al., Sci Transl Med 7:308-321, 2015; Ueda and Stern, Yale J Biol Med 90:433-448, 2017). Veterinary medicine is in a unique position to provide research resources and information that may be readily applied to human disease (Kol et al., Sci Transl Med 7:308-321, 2015). Many inherited cardiomyopathies of humans are phenotypically and genotypically similar in veterinary species and ongoing research holds promise for aiding veterinary and human patients alike (Basso et al., Circulation 109:1180-1185, 2004; Fox et al., Cardiovasc Pathol 23:28-34, 2014; Fox et al., Circulation 102:1863-1870, 2000; Kittleson et al., J Vet Cardiol 17 Suppl 1:S53-73, 2015; Ueda and Stern, Yale J Biol Med 90:433-448, 2017). This article presents the current knowledge of inherited cardiomyopathies in dogs, cats, and non-human primates, with a goal of identifying areas of translational research and future directions. PMID- 30284023 TI - Lisinopril versus lisinopril and losartan for mild childhood IgA nephropathy: a randomized controlled trial (JSKDC01 study). AB - BACKGROUND: Persistent proteinuria seems to be a risk factor for progression of renal disease. Its reduction by angiotensin-converting inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs) is renoprotective. Our previous pilot study showed that 2-year lisinopril therapy is effective and safe for children with mild IgA nephropathy. When combined with ACEI and ARB, reported results are of greater decrease in proteinuria than monotherapy in chronic glomerulonephritis, including IgA nephropathy. To date, however, there have been no randomized controlled trials in children. METHODS: This is an open-label, multicenter, prospective, and randomized phase II controlled trial of 63 children with biopsy-proven proteinuric mild IgA nephropathy. We compared efficacy and safety between patients undergoing lisinopril monotherapy and patients undergoing combination therapy of lisinopril and losartan to determine better treatment for childhood proteinuric mild IgA nephropathy. RESULTS: There was no difference in proteinuria disappearance rate (primary endpoint) between the two groups (cumulative disappearance rate of proteinuria at 24 months: 89.3% vs 89% [combination vs monotherapy]). Moreover, there were no significant differences in side effects between the two groups. CONCLUSIONS: We propose lisinopril monotherapy as treatment for childhood proteinuric mild IgA nephropathy as there are no advantages of combination therapy.

PMID- 30284025 TI - Objective and Subjective Sleep Efficiency in Adult Patients with Cystic Fibrosis and Impact on Quality of Life. AB - INTRODUCTION: Poor sleep quality and excessive daytime sleepiness are common in patients with cystic fibrosis (CF), and both are negatively correlated with health-related quality of life (HRQoL). The objective of our study was to evaluate subjective and objective sleep quality in adult CF patients and its effect on HRQoL. MATERIALS AND METHODS: This was a descriptive, prospective, cross-sectional study of CF patients > 18 years of age. Patients underwent nocturnal polysomnography (PSG) and were administered the Pittsburgh Sleep Quality Index questionnaire (PSQI) and the Cystic Fibrosis Quality of Life Questionnaire (CFQR 14 + Spain). RESULTS: The study included 23 patients, 14 women (61%). The mean age of the participants was 32 + 18 years. The mean PSQI score was 5.57 + 3.55; 13 (56.5%) of the patients were poor sleepers, and 13% reported poor sleep quality; seven (30%) had sleep latency > 30 min, 10 (43.5%) had sleep efficiency < 85%. Nineteen underwent polysomnography. According to PSG measurements, sleep efficiency was less than 90% in 61% of the patients. Pathological values were found for the following parameters: intra-sleep wakefulness in 12 patients (63%); microarousal index in 12 patients (63%); and apnea-hypopnea index (AHI) in 2 patients. The desaturation time with SpO2 < 90% (T90) was > 30% in 3 patients. We observed a significant correlation between PSQI and all dimensions of CFQR 14. CONCLUSIONS: Subjective and objective sleep efficiency decreases in adult CF patients. Sleep quality has an impact on HRQoL. The PSQI questionnaire was able to discriminate sleep quality. PMID- 30284026 TI - Endothelial Function in COPD Is in an Intermediate Position Between Healthy Subjects and Coronary Artery Disease Patients and Is Related to Physical Activity. AB - Patients with chronic obstructive pulmonary disease (COPD) have an increased risk of ischemic heart disease. Endothelial dysfunction may play a role in the onset of cardiovascular event. Previous studies showed an impaired endothelial function (measured by flow-mediated dilation, FMD) in COPD patients compared to healthy subjects. To the best of our knowledge no study has compared FMD in COPD and in cardiac (coronary artery disease, CAD) patients. We aimed to assess FMD in healthy subjects, COPD, CAD, and COPD + CAD. The main result is that FMD in COPD is reduced and is in an intermediate position between healthy subjects and CAD or COPD + CAD; this impairment can contribute to explain the higher prevalence of cardiovascular disease in COPD. The only determinant independently associated with FMD in all subjects is the physical activity level, irrespective of the traditional risk factors (i.e., smoke, dyslipidemia, hypertension). PMID- 30284027 TI - Fluorometric determination of quercetin by using graphitic carbon nitride nanoparticles modified with a molecularly imprinted polymer. AB - The authors describe a fluorescent probe for sensitive and selective determination of quercetin, an indicator for the freshness of drinks. The probe consists of silica ball encapsulated graphitic carbon nitride (g-C3N4) modified with a molecularly imprinted polymer (MIP). It was synthesized via reverse microemulsion. The resulting MIP@g-C3N4 nanocomposite was characterized by fluorescence spectroscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and X-ray powder diffraction. Quercetin quenches the fluorescence of the MIP@g-C3N4 probe. The effect was used to quantify quercetin in grape juice, tea juice, black tea, and red wine by fluorometry (lambdaexc = 350 nm, lambdaem = 460 nm). Response is linear in the 10-1000 ng mL-1 quercetin concentration range. The detection limit is 2.5 ng mL-1, recoveries range between 90.7 and 94.1%, and relative standard deviations are between 2.1 and 5.5%. Graphical abstract Schematic of the synthesis of the MIP@g-C3N4 by a reverse microemulsion method. The probe was applied for the selective recognition and fluorometric determination of quercetin. PMID- 30284028 TI - Antagonist muscle architecture and aponeurosis/tendon strain of biceps femoris long head during maximal isometric efforts. AB - INTRODUCTION: Examination of the mechanical behavior of the hamstrings when acting as antagonists provides information about loading of this muscle group and its role for joint stability during forceful quadriceps contractions. The aim of this study was to quantify biceps femoris long head fascicle length (FL), angle of pennation (PA) and distal tendon/aponeurosis strain during maximum voluntary contraction efforts of the knee extensors using real-time ultrasound. METHODS: Fourteen participants performed passive joint movements and maximum voluntary knee extension and flexion efforts of the knee flexors at 0 degrees , 45 degrees and 90 degrees of knee flexion. An ultrasound probe was used to visualize FL, PA and tendon/aponeurosis strain from the distal part of the muscle. RESULTS: Two way analysis of variance designs indicated that: (a) antagonist BFlh tendon/aponeurosis strain increased significantly up to 2.77 +/- 1.25% relative to rest (p < 0.05). The FL increased non-significantly (2.86 +/- 6.81%) while the PA was unaltered during isometric MVC efforts of the knee extensors (p > 0.05) (b) FL, PA and tendon/aponeurosis strain of the BFlh when acting as antagonist were not significantly affected by knee joint angular position (p > 0.05). CONCLUSIONS: Antagonist hamstring function takes the form of a lengthened tendon/aponeurosis, no fascicle shortening and submaximal neural activation. Future research could examine whether exercise interventions that aim to alter tendon/aponeurosis mechanical properties of the hamstrings when acting as antagonists are beneficial for injury prevention and rehabilitation. PMID- 30284029 TI - Pain management in abdominal surgery. AB - BACKGROUND: Abdominal surgery has undergone major changes during the last two decades with a general shift from open, invasive surgery to closed minimally invasive surgery. Accordingly, pain management strategies have also changed, especially with the introduction of ultrasound-guided abdominal wall blocks. Despite laparoscopic abdominal surgery classified as minimal, pain can be quite significant and needs to be addressed appropriately. PURPOSE: This narrative review focuses on adequate pain strategies for various types of surgery. The respective techniques are described and examples of specific pain management strategies given. Advantages and disadvantages of techniques are discussed. This review can serve as a sort of empirical guideline and orientation for the reader to develop their own strategy as well as bringing surgeons up-to-date with the latest anesthetic techniques. CONCLUSION: Pain is not less or less relevant in minimally invasive surgery. New hallmarks of a multimodal pain strategy are abdominal wall blocks, either as single shot or continuously. Minor open surgery is best performed under a combination of loco-regional blocks and continuous sedation. Abdominal wall blocks, NSAIDs, and short-acting opioids given by nurses or as PCA present the best multimodal pain strategy in abdominal surgery. Epidural analgesia and spinal anesthesia have become second-line options or are reserved for specific patient morbidities or surgical requirements.

PMID- 30284031 TI - An optoelectronic tongue based on an array of gold and silver nanoparticles for analysis of natural, synthetic and biological antioxidants. AB - A colorimetric array, which can discriminate 20 food antioxidants of natural, synthetic and biological groups, is described. It consists of gold and silver nanoparticles that were synthesized using six different reducing and/or capping agents. The function of the array relies on the interaction of the antioxidants with the nanoparticles which causes aggregation or morphological changes. This, in turn, causes a change in the sensors' colors. The array produces a unique combination of colors for each antioxidant. The resulting colorations are determined by recording the absorbances of the arrays at wavelengths of 405, 450, 490 and 630 nm, or by capturing the images with a digital camera. The discriminatory ability of the array is investigated by principle component analysis and hierarchical cluster analysis. The method was applied to quantitative assay of gallic acid, caffeic acid, catechin, dopamine, citric acid, butylated hydroxytoluene and ascorbic acid. The respective limits of detection are 4.2, 13, 53, 6.9, 47, 3.5 and 43 nM, respectively. The simultaneous determination of 5 different antioxidants is achieved utilizing partial least square regression. The root mean square errors for prediction of the test set are 0.0650, 0.0782, 0.811, 0.0206 and 0.135 nM for gallic acid, catechin, butylated hydroxytoluene, dopamine, and ascorbic acid, respectively. This method demonstrates excellent potential for analysis of antioxidants in beverages such as tea and lemon juice. Graphical abstract Schematic of a method for the simultaneous determination of several antioxidants based on changes in the color of gold and silver nanoparticles. The antioxidants cause aggregation and/or morphological changes which can be detected by using both image analysis or by colorimetry. PMID- 30284033 TI - Melanin-concentrating hormone neurons promote rapid eye movement sleep independent of glutamate release. AB - Neurons containing melanin-concentrating hormone (MCH) in the posterior lateral hypothalamus play an integral role in rapid eye movement sleep (REMs) regulation. As MCH neurons also contain a variety of other neuropeptides [e.g., cocaine- and amphetamine-regulated transcript (CART) and nesfatin-1] and neurotransmitters (e.g., glutamate), the specific neurotransmitter responsible for REMs regulation is not known. We hypothesized that glutamate, the primary fast-acting neurotransmitter in MCH neurons, is necessary for REMs regulation. To test this hypothesis, we deleted vesicular glutamate transporter (Vglut2; necessary for synaptic release of glutamate) specifically from MCH neurons by crossing MCH-Cre mice (expressing Cre recombinase in MCH neurons) with Vglut2flox/flox mice (expressing LoxP-modified alleles of Vglut2), and studied the amounts, architecture and diurnal variation of sleep-wake states during baseline conditions. We then activated the MCH neurons lacking glutamate neurotransmission using chemogenetic methods and tested whether these MCH neurons still promoted REMs. Our results indicate that glutamate in MCH neurons contributes to normal diurnal variability of REMs by regulating the levels of REMs during the dark period, but MCH neurons can promote REMs even in the absence of glutamate. PMID- 30284034 TI - Mutant superoxide dismutase aggregates from human spinal cord transmit amyotrophic lateral sclerosis. AB - Motor neurons containing aggregates of superoxide dismutase 1 (SOD1) are hallmarks of amyotrophic lateral sclerosis (ALS) caused by mutations in the gene encoding SOD1. We have previously reported that two strains of mutant human (h) SOD1 aggregates (denoted A and B) can arise in hSOD1-transgenic models for ALS and that inoculation of such aggregates into the lumbar spinal cord of mice results in rostrally spreading, templated hSOD1 aggregation and premature fatal ALS-like disease. Here, we explored whether mutant hSOD1 aggregates with prion like properties also exist in human ALS. Aggregate seeds were prepared from spinal cords from an ALS patient carrying the hSOD1G127Gfs*7 truncation mutation and from mice transgenic for the same mutation. To separate from mono-, di- or any oligomeric hSOD1 species, the seed preparation protocol included ultracentrifugation through a density cushion. The core structure of hSOD1G127Gfs*7 aggregates present in mice was strain A-like. Inoculation of the patient- or mouse-derived seeds into lumbar spinal cord of adult hSOD1-expressing mice induced strain A aggregation propagating along the neuraxis and premature fatal ALS-like disease (p < 0.0001). Inoculation of human or murine control seeds had no effect. The potencies of the ALS patient-derived seed preparations were high and disease was initiated in the transgenic mice by levels of hSOD1G127Gfs*7 aggregates much lower than those found in the motor system of patients carrying the mutation. The results suggest that prion-like growth and spread of hSOD1 aggregation could be the primary pathogenic mechanism, not only in hSOD1 transgenic rodent models, but also in human ALS.

PMID- 30284036 TI - Alginate immobilization of Morus alba L. cell suspension cultures improved the accumulation and secretion of stilbenoids. AB - Morus alba L. (Moraceae) has been used in traditional medicine for the treatment of several illnesses. Recent research also revealed several pharmacological activities from many groups of secondary metabolites, including the stilbenoids mulberroside A, oxyresveratrol, and resveratrol, which are promising compounds for cosmetic and herbal supplement products. In our previous study, cell cultures of M. alba showed high productivity of these compounds. In this study, we attempted to develop immobilized cell cultures of M. alba and to test the effect of elicitors and precursors on the production of stilbenoids. The immobilization of the M. alba cells significantly promoted the secretion of mulberroside A into the extracellular matrix and culture media to 60%, while enhancing the level of oxyresveratrol and resveratrol by 12- and 27-fold, respectively. The elicitation of immobilized cells with a combination of 50 uM methyl jasmonate and 0.5 mg/mL yeast extract for 24 h promoted a twofold increase in the production of all three stilbenoids. Furthermore, the addition of 0.05 mM L-phenylalanine, 0.03 mM L tyrosine, or a combination resulted in the enhancement of mulberroside A production for up to twofold. The addition of L-tyrosine significantly enhanced the production of oxyresveratrol and resveratrol. This is the first report of stilbenoid production using immobilized cell cultures of M. alba. The cultures have benefits over normal cell suspension cultures by promoting the secretion of mulberroside A and enhancing the levels of oxyresveratrol and resveratrol. Thus, it could be a candidate method for the production of these stilbenoids. PMID- 30284037 TI - Spinocerebellar ataxia: an update. AB - Spinocerebellar ataxia (SCA) is a heterogeneous group of neurodegenerative ataxic disorders with autosomal dominant inheritance. We aim to provide an update on the recent clinical and scientific progresses in SCA where numerous novel genes have been identified with next-generation sequencing techniques. The main disease mechanisms of these SCAs include toxic RNA gain-of-function, mitochondrial dysfunction, channelopathies, autophagy and transcription dysregulation. Recent studies have also demonstrated the importance of DNA repair pathways in modifying SCA with CAG expansions. In addition, we summarise the latest technological advances in detecting known and novel repeat expansion in SCA. Finally, we discuss the roles of antisense oligonucleotides and RNA-based therapy as potential treatments. PMID- 30284038 TI - Vitamin D for the treatment of multiple sclerosis: a meta-analysis. AB - OBJECTIVE: There is an association between latitude, relative vitamin D deficiency and risk of multiple sclerosis (MS), and an association between vitamin D and disease progression. We have performed a meta-analysis with the aim of investigating the role of therapeutic vitamin D in MS. METHODS: A systematic search of databases was performed to identify clinical trials assessing vitamin D in patients with relapsing-remitting MS. Studies were selected based on inclusion and exclusion criteria. Analysis was performed using RevMan 5.3 software. RESULTS: Twelve studies involving 950 patients were included in the final analysis. Studies were divided into four groups because of heterogeneity in study design. Studies were judged to be at low or unclear risk of bias, except in three studies, and this was confirmed by funnel plots. No statistically significant difference was seen for any of the outcome measures. There were non-significant trends in favour of vitamin D for all outcome measures, particularly when only placebo-controlled studies were included. Dose comparison studies showed a significant increase in annualised relapse rate (mean difference 0.15 [95%CI 0.01 0.30]) and non-significant trends of increased Expanded Disability Status Scale and gadolinium-enhancing lesions for the higher-dose arms. CONCLUSION: These findings suggest that vitamin D supplementation may have a therapeutic role in the treatment of MS. However, there is uncertainty with regard to the most appropriate dose, with high doses potentially being associated with worse outcomes. There remains the need for further well-performed randomised, dose ranging, placebo-controlled trials of vitamin D in MS. PMID- 30284039 TI - ASCO, NCCN, MASCC/ESMO: a comparison of antiemetic guidelines for the treatment of chemotherapy-induced nausea and vomiting in adult patients. AB - Chemotherapy-induced nausea and vomiting (CINV) is a common toxicity that may impair the quality of life of patients with a variety of early- and end-stage malignancies. In light of recent changes in the optimal management of CINV, we undertook this narrative review to compare the latest guidelines published by ASCO (2017), NCCN (2018), and MASCC/ESMO (2016). The processes undertaken by each organization to evaluate existing literature were also described. Although ASCO, NCCN, and MASCC/ESMO guidelines for the treatment and prevention of CINV share many fundamental similarities, literature surrounding low and minimal emetic risk regimens is lacking. Data regarding the use of complementary alternative medicine for CINV is particularly scarce and in need of further investigation. PMID- 30284040 TI - Design, implementation, and evaluation of an intervention to improve referral to smoking cessation services in breast cancer patients. AB - PURPOSE: Smoking is a risk factor for poor outcomes following breast reconstructive surgery. This project aimed to design and implement an intervention to consistently refer all breast cancer patients to tobacco treatment services. METHODS: In formative work, a set of processes for providers to consistently refer patients to a tobacco treatment specialist at the Nicotine Dependence Center (NDC) was designed. Elements included consistent documentation of smoking status, provider advice specific to the benefits of quitting to cancer care, referral to NDC using an "opt-out" strategy that emphasized smoking cessation as a standard part of breast cancer treatment, and reinforcement of the importance of the referral by multiple personnel. The number of referrals to the NDC and number of patients who attended their scheduled NDC appointment were measured before and 1 year after implementation. Qualitative evaluation was performed using semi-structured interviews with participating providers and patients regarding acceptability. RESULTS: The proportion of smoking patients referred to the NDC increased from 29% (22/75) before the intervention to 74% (20/27) afterward. Among those referred, attendance at the consultation increased from 41% (9/22) to 75% (15/20). This occurred despite provider interviews revealing knowledge gaps about the referral process and evidence of provider adaptation to accommodate personal practice. Feasibility and acceptability of the intervention were high. CONCLUSION: These findings suggest that similar referral interventions for all cancer patients should be pursued with the aim of embedding tobacco dependence treatment seamlessly and consistently into the cancer treatment plan of every patient who smokes cigarettes. PMID- 30284041 TI - Validation of dynamic random dot stereotests in pediatric vision screening. AB - PURPOSE: Stereo vision tests are widely used in the clinical practice for screening amblyopia and amblyogenic conditions. According to literature, none of these tests seems to be suitable to be used alone as a simple and reliable tool. There has been a growing interest in developing new types of stereo vision tests, with sufficient sensitivity to detect amblyopia. This new generation of assessment tools should be computer based, and their reliability must be statistically warranted. The present study reports the clinical evaluation of a screening system based on random dot stereograms using a tablet as display. Specifically, a dynamic random dot stereotest with binocularly detectable Snellen E optotype (DRDSE) was used and compared with the Lang II stereotest. METHODS: A total of 141 children (aged 4-14, mean age 8.9) were examined in a field study at the Department of Ophthalmology, Pecs, Hungary. Inclusion criteria consisted of diagnoses of amblyopia, anisometropia, convergent strabismus, and hyperopia. Children with no ophthalmic pathologies were also enrolled as controls. All subjects went through a regular pediatric ophthalmological examination before proceeding to the DRDSE and Lang II tests. RESULTS: DRDSE and Lang II tests were compared in terms of sensitivity and specificity for different conditions. DRDSE had a 100% sensitivity both for amblyopia (n = 11) and convergent strabismus (n = 21), as well as a 75% sensitivity for hyperopia (n = 36). However, the performance of DRDSE was not statistically significant when screening for anisometropia. On the other hand, Lang II proved to have 81.8% sensitivity for amblyopia, 80.9% for strabismus, and only 52.8% for hyperopia. The specificity of DRDSE was 61.2% for amblyopia, 67.3% for strabismus, and 68.6% for hyperopia, respectively. Conversely, Lang II showed about 10% better specificity, 73.8% for amblyopia, 79.2% for strabismus, and 77.9% for hyperopia. CONCLUSIONS: The DRDSE test has a better sensitivity for the detection of conditions such as amblyopia or convergent strabismus compared with Lang II, although with slightly lower specificity. If the specificity could be further improved by optimization of the stimulus parameters, while keeping the sensitivity high, DRDSE would be a promising stereo vision test for screening of amblyopia. PMID- 30284042 TI - Tracking Nosocomial Diseases at Individual Level with a Real-Time Indoor Positioning System. AB - Our research is motivated by the rapidly-evolving outbreaks of rare and fatal infectious diseases, for example, the severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome. In many of these outbreaks, main transmission routes were healthcare facility-associated and through person-to person contact. While a majority of existing work on modelling of the spread of infectious diseases focuses on transmission processes at a community level, we propose a new methodology to model the outbreaks of healthcare-associated infections (HAIs), which must be considered at an individual level. Our work also contributes to a novel aspect of integrating real-time positioning technologies into the tracking and modelling framework for effective HAI outbreak control and prompt responses. Our proposed solution methodology is developed based on three key components - time-varying contact network construction, individual-level transmission tracking and HAI parameter estimation - and aims to identify the hidden health state of each patient and worker within the healthcare facility. We conduct experiments with a four-month human tracking data set collected in a hospital, which bore a big nosocomial outbreak of the 2003 SARS in Hong Kong. The evaluation results demonstrate that our framework outperforms existing epidemic models for characterizing macro-level phenomena such as the number of infected people and epidemic threshold. PMID- 30284043 TI - SERS based aptasensor for ochratoxin A by combining Fe3O4@Au magnetic nanoparticles and Au-DTNB@Ag nanoprobes with multiple signal enhancement. AB - A SERS-based aptasensor for ochratoxin A (OTA) is described. It is making use of Fe3O4@Au magnetic nanoparticles (MGNPs) and of Au@Ag nanoprobes modified with the Raman reporter 5,5-dithiobis-(2-nitrobenzoic acid; DTNB). Au-DTNB@Ag NPs were modified with the OTA aptamer (aptamer-GSNPs) and used as Raman signal probes. The SERS peak of DTNB at 1331 cm-1 was used for quantitative analysis. MGNPs modified with cDNA (cDNA-MGNPs) were used as capture probes and reinforced substrates. When the Au-DTNB@Ag-Fe3O4@Au complexes are formed through oligonucleotide hybridization, the Raman signal intensity of the Raman probe is significantly enhanced. If the OTA concentration in samples increases, more Raman signal probes (aptamer-GSNPs) will dissociate from the cDNA-MGNPs because more OTA aptamer is bound by OTA. This leads to a lower Raman signal after magnetic separation. Under the optimal conditions, the detection limit for OTA is 0.48 pg.mL-1 based on 3sigma criterion. This is attributed to the multiple Raman signal enhancement and the good performance of the OTA aptamer. The good recovery and accuracy of the assay was confirmed by evaluating spiked samples of wine and coffee. Graphical abstract Schematic of an aptamer based SERS assay for OTA by integrating Fe3O4@AuNPs (MGNPs) with Au-DTNB@Ag NPs with multiple signal enhancement. Aptamer modified Au-DTNB@Ag NPs are used as Raman probes, and MGNPs modified with cDNA are used as capture probes and reinforced substrates. PMID- 30284045 TI - CRISPR RNA-guided DNA cleavage by reconstituted Type I-A immune effector complexes. AB - Diverse CRISPR-Cas immune systems protect archaea and bacteria from viruses and other mobile genetic elements. All CRISPR-Cas systems ultimately function by sequence-specific destruction of invading complementary nucleic acids. However, each CRISPR system uses compositionally distinct crRNP [CRISPR (cr) RNA/Cas protein] immune effector complexes to recognize and destroy invasive nucleic acids by unique molecular mechanisms. Previously, we found that Type I-A (Csa) effector crRNPs from Pyrococcus furiosus function in vivo to eliminate invader DNA. Here, we reconstituted functional Type I-A effector crRNPs in vitro with recombinant Csa proteins and synthetic crRNA and characterized properties of crRNP assembly, target DNA recognition and cleavage. Six proteins (Csa 4-1, Cas3", Cas3', Cas5a, Csa2, Csa5) are essential for selective target DNA binding and cleavage. Native gel shift analysis and UV-induced RNA-protein crosslinking demonstrate that Cas5a and Csa2 directly interact with crRNA 5' tag and guide sequences, respectively. Mutational analysis revealed that Cas3" is the effector nuclease of the complex. Together, our results indicate that DNA cleavage by Type I-A crRNPs requires crRNA-guided and protospacer adjacent motif-dependent target DNA binding to unwind double-stranded DNA and expose single strands for progressive ATP-dependent 3'-5' cleavage catalyzed by integral Cas3' helicase and Cas3" nuclease crRNP components.

AB - BACKGROUND: Deep learning has become a new trend of image recognition tasks in the field of medicine. We developed an automated gastritis detection system using double-contrast upper gastrointestinal barium X-ray radiography. METHODS: A total of 6520 gastric X-ray images obtained from 815 subjects were analyzed. We designed a deep convolutional neural network (DCNN)-based gastritis detection scheme and evaluated the effectiveness of our method. The detection performance of our method was compared with that of ABC (D) stratification. RESULTS: Sensitivity, specificity, and harmonic mean of sensitivity and specificity of our method were 0.962, 0.983, and 0.972, respectively, and those of ABC (D) stratification were 0.925, 0.998, and 0.960, respectively. Although there were 18 false negative cases in ABC (D) stratification, 14 of those 18 cases were correctly classified into the positive group by our method. CONCLUSIONS: Deep learning techniques may be effective for evaluation of gastritis/non-gastritis. Collaborative use of DCNN-based gastritis detection systems and ABC (D) stratification will provide more reliable gastric cancer risk information. PMID- 30284047 TI - Malnutrition in type 2 diabetic patients does not affect healing of foot ulcers. AB - AIM: Protein-energy malnutrition is known to be involved in wound healing. While wound healing in patients with diabetic foot ulcers (DFU) is a complex and multifactorial process, the role of malnutrition in this case has rarely been explored. The objective of this study was to determine whether the nutritional status of diabetic patients influences the healing of DFU. METHODS: 48 patients were included in this prospective, single-center study. All patients with comorbidities or factors involving malnutrition or influencing biological measurements were excluded. Patients were followed up for 24 weeks. RESULTS: The malnutrition rate was 29.2% at baseline and 25.6% at the end of the study. The difference was not significant. Of the 35 patients with wound healing, 29% were undernourished at inclusion and 17% at the end of the study. Of the 12 patients without wound healing, 50% were undernourished at inclusion, and 42% at the end of the study. These differences were not significant. Rate and speed of wound healing were not associated with malnutrition at inclusion. 15% of patients without malnutrition at baseline had final malnutrition. CONCLUSION: We demonstrated that wound healing was not affected by the initial presence of malnutrition. In our study, there is no evidence to support nutritional intervention to improve wound healing in diabetic patients. Nevertheless, malnutrition is responsible for an increase in morbidity and mortality and it is essential to identify malnutrition systematically for all patients with DFU, initially and during follow-up to treat it quickly and efficiently. PMID- 30284048 TI - In Situ Electrospinning Iodine-Based Fibrous Meshes for Antibacterial Wound Dressing. AB - For effective application of electrospinning and electrospun fibrous meshes in wound dressing, we have in situ electrospun poly(vinyl pyrrolidone)/iodine (PVP/I), PVP/poly(vinyl pyrrolidone)-iodine (PVPI) complex, and poly(vinyl butyral) (PVB)/PVPI solutions into fibrous membranes by a handheld electrospinning apparatus. The morphologies of the electrospun fibers were examined by SEM, and the hydrophobicity, gas permeability, and antibacterial properties of the as-spun meshes were also investigated. The flexibility and feasibility of in situ electrospinning PVP/I, PVP/PVPI, and PVB/PVPI membranes, as well as the excellent gas permeabilities and antibacterial properties of the as-spun meshes, promised their potential applications in wound healing. PMID- 30284050 TI - Photovoltaic Performance of Pin Junction Nanocone Array Solar Cells with Enhanced Effective Optical Absorption. AB - The photovoltaic performance of axial and radial pin junction GaAs nanocone array solar cells is investigated. Compared with the cylinder nanowire arrays, the nanocone arrays not only improve the whole optical absorption but more importantly enhance the effective absorption (absorption in the depletion region). The enhanced effective absorption is attributed to the downward shift and extension of the absorption region induced by the shrinking top, which dramatically suppresses the absorption loss in the high-doped top region and enhances the absorption in the depletion region. The highest conversion efficiencies for axial and radial GaAs nanocone solar cells are 20.1% and 17.4%, obtained at a slope angle of 5 degrees and 6 degrees , respectively, both of which are much higher than their cylinder nanowire counterparts. The nanocone structures are promising candidates for high-efficiency solar cells. PMID- 30284049 TI - Biomarkers in Food Allergy. AB - PURPOSE OF REVIEW: To familiarize the reader with the concept of precision medicine in food allergy by dealing with the current biomarkers for the diagnosis, prognosis, and management of the disease. RECENT FINDINGS: Many efforts have been devoted in order to characterize reliable biomarkers able to identify specific phenotypes and endotypes in food allergy. Specific IgE (sIgE), sIgE/total IgE ratios, and T cell assays are just a few candidates that have been investigated over time. With the advent of omics sciences, a new era is commencing. A better understanding of pathogenesis of food allergy and mechanisms of action of the different therapeutic options will allow the accurate selection of the appropriate patient. In the near future, advances in technologies and data interpretation will allow a better understanding of the pathogenesis of food allergy and the identification of proper biomarkers for a personalized treatment tailored on the specific patient's profile. PMID- 30284051 TI - Effect of L-Citrulline Supplementation on Blood Pressure: a Systematic Review and Meta-Analysis of Clinical Trials. AB - PURPOSE OF REVIEW: Several interventional studies assessed the impact of dietary supplements on blood pressure. The aim of the present systematic review and meta analysis was to determine the efficacy of L-citrulline supplementation on blood pressure. RECENT FINDING: Pubmed, Scopus, Google Scholar, and ISI Web of Science were comprehensively searched until May 2018 to assess whether L-citrulline reduces blood pressure. Human clinical trials which reported the effect of L citrulline supplementation on aortic and brachial blood pressure were included. Characteristics of studies and potential sources of heterogeneity were tabulated. A subgroup analysis was performed to attenuate observed inter-study heterogeneity. A total of five interventions were found for meta-analysis. The impact of L-citrulline on brachial systolic (change 0.28 mmHg; 95% CI - 2.87, 2.31 mmHg) and diastolic (change - 1.56 mmHg; 95% CI - 4.32, 1.20 mmHg) blood pressure was not significant. Also, there was no changes in aortic systolic (change 0.22 mmHg; 95% CI - 4.81, 4.38 mmHg) and diastolic (change 0.26 mmHg; 95% CI - 2.27, 2.80 mmHg) blood pressure after L-citrulline supplementation. Participants' body weight status was a source of observed heterogeneity. The present systematic review and meta-analysis suggests that L-citrulline supplementation had no beneficial effect on blood pressure. PMID- 30284052 TI - Multilayered Deep Structure Tensor Delaunay Triangulation and Morphing Based Automated Diagnosis and 3D Presentation of Human Macula. AB - Maculopathy is the group of diseases that affects central vision of a person and they are often associated with diabetes. Many researchers reported automated diagnosis of maculopathy from optical coherence tomography (OCT) images. However, to the best of our knowledge there is no literature that presents a complete 3D suite for the extraction as well as diagnosis of macula. Therefore, this paper presents a multilayered convolutional neural networks (CNN) structure tensor Delaunay triangulation and morphing based fully autonomous system that extracts up to nine retinal and choroidal layers along with the macular fluids. Furthermore, the proposed system utilizes the extracted retinal information for the automated diagnosis of maculopathy as well as for the robust reconstruction of 3D macula of retina. The proposed system has been validated on 41,921 retinal OCT scans acquired from different OCT machines and it significantly outperformed existing state of the art solutions by achieving the mean accuracy of 95.27% for extracting retinal and choroidal layers, mean dice coefficient of 0.90 for extracting fluid pathology and the overall accuracy of 96.07% for maculopathy diagnosis. To the best of our knowledge, the proposed framework is first of its kind that provides a fully automated and complete 3D integrated solution for the extraction of candidate macula along with its fully automated diagnosis against different macular syndromes.

AB - Ruminal thiamine deficiencies occur when dairy cows are overfed with high concentrate diet, and thiamine supplementation has been proved to attenuate high concentrate diet induced SARA. However, there is limited knowledge of the relationship between thiamine supplementation in high-concentrate diets and ruminal fungi. In order to investigate the impacts of thiamine supplementation on ruminal fungi, twelve Chinese Holstein dairy cows were randomly assigned into three treatments: control diet (CON; 20% starch, dry matter basis), high concentrate diet (HC; 33.2% starch, dry matter basis) and high-concentrate diet supplemented with 180 mg thiamine/kg dry matter intake. Dry matter intake and milk production were recorded during the experimental periods. On day 21, rumen fluid samples were collected at 3 h postfeeding and ruminal pH, thiamine concentration and volatile fatty acids were measured. Metagenome sequencing method was conducted to detect ruminal fungi composition. Feeding HC significantly decreased dry matter intake, milk production, ruminal pH, ruminal acetate and thiamine concentration, however, significantly increased propionate and isovalerate (P < 0.05). These changes were inversed by thiamine supplementation (P < 0.05). Totally, seven phyla and almost 1050 species of rumen fungi were identified across all samples in which especially, 3 genera and 10 species of strictly anaerobic fungi phylum Neocallimastigomycota was found. Principal coordinate analysis indicated that feeding HC and thiamine supplementation caused a significant inverse in ruminal fungi composition. Feeding HC significantly decreased the abundance of fungi compared with CON (P < 0.05) while thiamine supplementation significantly increased the abundance of ruminal fungi (P < 0.05). These results indicated that thiamine supplementation may effectively attenuate rumen metabolic disorder caused by HC diet through buffering the ruminal pH, shifting the rumen fermentation pattern and increasing the abundance of ruminal fungi. The findings in this study could therefore contribute to the further understanding of the mechanism of thiamine's function in dairy cows.

HD is seldom disease characterized by juvenile muscular atrophy of upper extremities and benign course. All cases were diagnosed in the Research Center of Neurology (Moscow, Russia) during the year 2015-2017. Such methods as MRI (magnetic resonance imaging), EMG (electromyography), and NCS (nerve conduction studies) have been used to confirm diagnosis of HD. Transcranial magnetic stimulation was used to exclude upper motor neuron involvement in two cases. The original scale of neurological disturbances in HD has been proposed by authors to reveal correlations of HD severity with age of patients and duration of disease.Most of patients with HD are young males with common clinical signs. Detected MRI and EMG data were also comparable with previous publications. Independence of HD severity from age and duration of the disease may be the result of individual physical characteristics of dura mater and other structures of the cervical vertebra. In some our cases, amyotrophic lateral sclerosis and other neurological disorders were misdiagnosed before. In view of different prognosis in these pathologies and possible correction of HD, early diagnosis is very important. PMID- 30284054 TI - Plant specific emission pattern of biogenic volatile organic compounds (BVOCs) from common plant species of Central India. AB - In this study, we examined 49 representative plant species of the Achanakmar Amarkantak Biosphere Reserve (AABR) forest of Central India for emission of a number of biogenic volatile organic compounds (BVOCs). The BVOCs emissions from seven plant species are reported here for the first time. The emission rates of different plant species were ranged from negligible to 80.6 +/- 0.82 (MUgg-1 h 1). Forty-seven plant species were found to emit isoprene and monoterpenes (23 high emitters, 12 moderate emitters, and 12 low emitters). Dalbergia sissoo showed the maximum total average volatile organic compound (TAVOC) emission rates (80.6 MUgg-1 h-1). The percentage composition of monoterpenes was also varied across different plant species. Alpha-pinene (alpha-pinene) was found as the most dominant monoterpene with about 41.40% of the total monoterpene emission. The highest emission range of alpha-pinene (7.8 MUg g-1 h-1) was observed in Murraya koenigii. Carene was emitted only from two species (i.e., Mangifera indica and Terminalia tomentosa). When the emission rates of present study were compared to previous studies, there were considerable differences even for the same species. The study also reports the emission of BVOCs from Shorea robusta for the first time which is the most dominant plant species of the AABR (covering 60% of the total forest area). PMID- 30284057 TI - On the electron flow sequence driving the hydrometallation of acetylene by lithium hydride. AB - The sequence of the electronic flow driving the hydrometallation of acetylene by lithium hydride (and that of the opposite beta-hydride elimination reaction from the alkenyl metal intermediate), was examined within the perspective provided by the bonding evolution theory (BET). The analysis was based on the application of catastrophe theory to the changes of the electron localization function topology along the intrinsic reaction coordinate. The description of the electronic processes occurring on the process was represented in terms of topological structural stability domains (SSDs) and the associated elementary bifurcation catastrophes. Within such a framework of representation, the "evolution" of the system through the different SSDs reveals the key chemical events driving the transformation, including the large polarization effect as a consequence of Pauli repulsion between ions of the positive cationic metal on the hydride domain, the activation of the CC triple bond to attack the cationic center, and the agostic stabilizing interactions involving the hardest cationic metal, followed by the attack of the hydride center. These results contribute to emphasizing the intrinsic value and usefulness of using topological-based approaches and associated tools to increase our knowledge and understanding of the subtleties underlying the electronic flow as nuclei evolve along the reaction coordinate, providing detailed and complementary insights in comparison to other interpretative tool such those based on orbital-based representations, concerning the intimate nature of the electronic rearrangement of key mechanistic processes in chemistry. Graphical abstract The sequence of the electron flow (indicated by letters a and b) along the intrinsic reaction path for the hydrometallation of acetylene by lithium hydride to yield ethenyl lithium via a four-membered transition structure (TS), as determined within the bonding evolution theory to provide the key chemical events driven the changes in the key bonding patterns.

AB - Weathering of wooden temples is attributable to temperature and humidity. Here, we explore the microclimatic characteristics of a traditional Korean temple; we measured temperature, relative humidity, wind velocity, and wind direction at one internal and five external points in/near Silsang Temple. Both the temperature and humidity varied by season. The internal and external daily temperature ranges were most similar in autumn, followed by spring, winter, and summer. The relative humidity inside was 40% greater (compared to outside) in spring and winter, but not in summer and autumn. Wind velocity variations within the temple were significant in certain seasons. Neither the outside temperature nor internal relative humidity was greatly affected by location. Correlations were evident between the outside temperature and relative humidity. PMID- 30284059 TI - Hemodynamic assessment of pulmonary hypertension in mice: a model-based analysis of the disease mechanism. AB - This study uses a one-dimensional fluid dynamics arterial network model to infer changes in hemodynamic quantities associated with pulmonary hypertension in mice. Data for this study include blood flow and pressure measurements from the main pulmonary artery for 7 control mice with normal pulmonary function and 5 mice with hypoxia-induced pulmonary hypertension. Arterial dimensions for a 21-vessel network are extracted from micro-CT images of lungs from a representative control and hypertensive mouse. Each vessel is represented by its length and radius. Fluid dynamic computations are done assuming that the flow is Newtonian, viscous, laminar, and has no swirl. The system of equations is closed by a constitutive equation relating pressure and area, using a linear model derived from stress strain deformation in the circumferential direction assuming that the arterial walls are thin, and also an empirical nonlinear model. For each dataset, an inflow waveform is extracted from the data, and nominal parameters specifying the outflow boundary conditions are computed from mean values and characteristic timescales extracted from the data. The model is calibrated for each mouse by estimating parameters that minimize the least squares error between measured and computed waveforms. Optimized parameters are compared across the control and the hypertensive groups to characterize vascular remodeling with disease. Results show that pulmonary hypertension is associated with stiffer and less compliant proximal and distal vasculature with augmented wave reflections, and that elastic nonlinearities are insignificant in the hypertensive animal.

AB - The effects of inlet VOCs (Volatile Organic Compounds) shifts on microbial community structure in a biofiltration system were investigated. A lab-scale biofilter was set up to treat eight VOCs sequentially. Short declines in removal efficiency appeared after VOCs shifts and then later recovered. The number of OTUs in the biofilter declined from 690 to 312 over time. At the phylum level, Actinobacteria and Proteobacteria remained dominant throughout the operation for all VOCs, with their combined abundance ranging from 60 to 90%. The abundances of Planctomycetes and Thermi increased significantly to 20% and 5%, respectively, with the intake of non-aromatic hydrocarbons. At the genus level, Rhodococcus was present in the highest abundance (>= 10%) throughout the experiment, indicating its wide degradability. Some potential degraders were also found; namely, Thauera and Pseudomonas, which increased in abundance to 19% and 12% during treatment with ethyl acetate and toluene, respectively. Moreover, the microbial metabolic activity declined gradually with time, and the metabolic profile of the toluene treating community differed significantly from those of other communities. PMID- 30284062 TI - A semi-dominant mutation in a CC-NB-LRR-type protein leads to a short-root phenotype in rice. AB - The mechanisms of plant defense against pathogen attack in plant leaves have been extensively studied. However, our understanding of plant defense mechanisms in plant roots is still limited. In this study, a semi-dominant mutant nrtp1-D (necrotic root tip 1), with a short-root phenotype, was characterized in rice. Map-based cloning revealed that NRTP1 encoded a typical coiled-coil nucleotide binding leucine rich repeat (CC-NB-LRR) type protein and the mutation caused an amino acid substitution in the Nucleotide-Binding adaptor shared by Apaf1, certain R genes and CED4 (NB-ARC) domain, which may cause constitutive auto activation of the NRTP1 protein. Gene expression analysis revealed that NRTP1 was preferentially expressed in rice roots. Expression of mutant nrtp1-D in tobacco leaves induced necrotic lesions, which indicated a common mechanism of plant defense response between leaves and roots. Transcriptome analysis revealed that many typical defense-response genes were differentially expressed in homozygous nrtp1-D. In addition, we also found differential expression of genes in pathways which had not previously been described as being associated with pathogen response. Histochemical analysis showed that the level of nitric oxide (NO), but not reactive oxygen species (ROS), was increased in homozygous nrtp1-D mutant roots. These results indicate that, in addition to the mechanism of defense response common to both roots and shoots, a novel pathway may also exist in rice roots, which does not operate in shoots. PMID- 30284063 TI - Droplet digital PCR using HER2/EIF2C1 ratio for detection of HER2 amplification in breast cancer tissues. AB - Breast cancers with amplification and overexpression of human epithelial growth factor receptor 2 (HER2) are associated with poor prognosis, and targeted for anti-HER2 therapy. Immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) are currently the recommended methods to asses HER2 overexpression/amplification. Droplet digital PCR (ddPCR), a highly accurate method to quantify DNA copy number, is potentially a robust alternative for HER2 diagnostics. In the FISH assay and most of previous ddPCR reports, chromosome 17 centromere (CEP17) has been used as the reference control to determine HER2/CEP17 ratio. Nevertheless, miss-classification could occur when HER2 is co-amplified with CEP17. To avoid this inherent defect, in the present study, we employed ddPCR assay using the human eukaryotic translation initiation factor 2C1 (EIF2C1) gene located at chromosome 1p34.3 as the reference control to quantify HER2 copy number in 31 frozen breast cancer tissues. HER2 status of these samples had been determined by FISH and classified as HER2-amplified and HER2-non-amplified breast cancers. The results showed that HER2 determined by ddPCR using HER2/EIF2C1 ratio was in good concordance with HER2 determined by FISH using HER2/CEP17 ratio, the concordance rate 87.1% (27/31), Kappa = 0.719. The sensitivity and specificity of ddPCR assay was 90% (9/10) and 85.7% (18/21), respectively. The median HER2/EIF2C1 copy number ratio in HER2-amplified cancers (6.55, range 1.3-17.3) was significantly higher than in HER2-non-amplified cancers (1.05, range 0.6-3.6, p < 0.001). This study demonstrated that ddPCR using HER2/EIF2C1 ratio could accurately assess HER2 status in frozen breast cancer tissues. Thus, our findings warrant further studies into breast cancer with HER2-equivocal by IHC/FISH. PMID- 30284064 TI - Sugar-sweetened beverage consumption and incidence of breast cancer: the Seguimiento Universidad de Navarra (SUN) Project. AB - PURPOSE: Breast cancer (BC) incidence is increasing worldwide. Higher insulin resistance may potentially lead to an increased risk of BC. Sugar-sweetened beverages (SSB) are an acknowledged dietary factor that increases insulin resistance. However, the association between SSB and BC has not been widely explored. We evaluated the association between baseline consumption of SSB and the incidence of BC among relatively young women in a cohort of Spanish university graduates. METHODS: We evaluated 10,713 middle-aged, Spanish female university graduates (median age 33) from the Seguimiento Universidad de Navarra (SUN) cohort, initially free of BC. SSB consumption was collected at baseline using a validated 136-item semi-quantitative food-frequency questionnaire. Incidence of BC was confirmed by a trained oncologist using medical records. We fitted Cox regression models to assess the relationship between baseline categories of SSB consumption and the incidence of BC during follow-up. We stratified the analyses by menopausal status. RESULTS: During 106,189 person years follow-up, 100 incident cases of BC were confirmed. Among postmenopausal women, regular consumption of SSB was associated with a significantly higher incidence of BC (HR 2.12; 95% CI 1.02, 4.41) in the fully adjusted model, compared to women who never or seldom consumed SSB. No association was found among premenopausal women (HR 1.16; 95% CI 0.66, 2.07). CONCLUSIONS: Even though the number of cases was small, in this Mediterranean cohort, we observed a direct association between SSB consumption and BC risk among postmenopausal women. Nonetheless further larger longitudinal studies are needed to support this association. PMID- 30284065 TI - Effect of an egg ovalbumin-derived protein hydrolysate on blood pressure and cardiovascular risk in adults with a mildly elevated blood pressure: a randomized placebo-controlled crossover trial. AB - PURPOSE: While animal and in vitro data demonstrate vasodilatory effects of egg white-derived peptides, human studies are lacking. We investigated for the first time the effects of an egg ovalbumin-derived protein hydrolysate on blood pressure (BP) and cardiovascular risk. METHODS: A double-blind, placebo controlled randomized crossover trial was implemented in 75 adults aged 50-70 years with systolic BP (130-<= 150 mmHg). Participants were randomized to an egg ovalbumin-derived protein hydrolysate (3 g/day) or placebo (3 g/day). Participants completed two 6-week periods separated by a 3-week washout. RESULTS: Data from 65 participants with a mean systolic BP (135.1 +/- 11 mmHg) were included. Mean office and central BP and arterial stiffness (assessed by carotid femoral pulse wave velocity (cfPWV) or pulse wave analysis (PWA)) did not change over time and no significant differences were observed between the egg protein hydrolysate and placebo groups (P > 0.05). Similarly, no significant effects of this egg ovalbumin-derived protein hydrolysate on blood lipid and glucose concentrations (P > 0.05) were observed. CONCLUSION: This is the first dietary intervention to investigate the effects of egg ovalbumin-derived protein hydrolysates on cardiovascular risk in humans. Despite promising findings from animal and in vitro studies, this RCT does not support the hypothesis that consumption of an egg ovalbumin-derived protein hydrolysate for 6 weeks in adults with a high-normal BP results in a reduction in BP or the modification of cardiovascular risk. PMID- 30284066 TI - Cereal fructan extracts alter intestinal fermentation to reduce adiposity and increase mineral retention compared to oligofructose. AB - PURPOSE: Intestinal fermentation of inulin-type fructans, including oligofructose, can modulate adiposity, improve energy regulation, and increase mineral absorption. We aimed to determine whether cereal fructans had greater effects on reducing adiposity and improving mineral absorption compared with oligofructose. METHODS: Thirty-two male Sprague-Dawley rats were randomly assigned to one of four dietary treatments that contained 0% fructan (control), or 5% fructan provided by oligofructose (OF), a barley grain fraction (BGF), or a wheat stem fraction (WSF). After 1 week on the diets, mineral absorption and retention was assessed. At 4 weeks, blood samples were collected for gut hormone analysis, adipose depots were removed and weighed, and caecal digesta was analyzed for pH and short-chain fatty acids (SCFA). RESULTS: The BGF and WSF, but not OF, had lower total visceral fat weights than the Control (p < 0.05). The fructan diets all lowered caecal pH and raised caecal digesta weight and total SCFA content, in comparison to the Control. Caecal propionate levels for OF were similar to the Control and higher for WSF (p < 0.05). Plasma peptide YY and glucagon-like peptide-1 levels were elevated for all fructan groups when compared to Control (p < 0.001) and gastric inhibitory peptide was lower for the WSF compared to the other groups (p < 0.05). The fructan diets improved calcium and magnesium retention, which was highest for WSF (p < 0.05). BGF and WSF in comparison to OF showed differential effects on fermentation, gut hormone levels, and adiposity. CONCLUSIONS: Cereal fructan sources have favorable metabolic effects that suggest greater improvements in energy regulation and mineral status to those reported for oligofructose. PMID- 30284067 TI - What attributes guide best practice for effective feedback? A scoping review. AB - There has been an observed increase in literature concerning feedback within the last decade, with the importance of feedback well documented. Current discourse promotes feedback as an interactive, dialogic process between the learner and the learning partner. While much has been written about effective feedback, less is known about key elements that support dialogic feedback. It is therefore important to investigate what is known about the elements that guide best practice for effective feedback. A scoping review of the extant literature following Arksey and O'Malley's methodology was conducted. A search of literature published in English identified sixty-one publications eligible for this review. Publications were representative of the international literature from both empirical and non-empirical sources. Feedback elements were extracted from the included publications and categorised into 11 core attributes. The attributes identified feedback as: being a process; criteria-based; requiring multiple forms and sources of data/evidence; needs to be desired by the recipient (i.e. invited and welcomed); timely; responsive to the learner (i.e. tailored to developmental needs/learning preferences of the learner); frequent; future-focussed; reciprocal (i.e. two-way); involves skilful interaction; and is multidimensional (i.e. engages the learner in more than one way). Despite the rhetoric on feedback as a 'dialogic process', a gap remains in our understanding around what is required to engage the learner as an equal partner in the feedback process. Further research exploring the impact of specific aspects of the feedback process on practice is required. PMID- 30284068 TI - Contradictions in clinical teachers' engagement in educational development: an activity theory analysis. AB - Many medical universities offer educational development activities to support clinical teachers in their teaching role. Research has focused on the scope and effectiveness of such activities and on why individual teachers attend. However, systemic perspectives that go beyond a focus on individual participants are scarce in the existing literature. Employing activity theory, we explored how clinical teachers' engagement in educational development was affected by the systems they act within. Three focus groups were held with clinical teachers from different professions. A thematic analysis was used to map the contradictions between the systems that the participants were part of and the manifestations of these contradictions in the system of education. In our model, clinical teachers were part of three activity systems directed by the objects of patient care, research and education respectively. Contradictions arose between these systems as their objects were not aligned. This manifested through the enacted values of the academic hospital, difficulties establishing educational discussions in the clinical workplace, the transient nature of educational employments, and impediments to developing a teacher identity. These findings offer insights into the complexities of engaging in educational development as clinical teachers' priorities interact with the practices and values of the academic hospital, suggesting that attention needs to shift from individual teachers to developing the systems in which they work. PMID- 30284069 TI - A rare solitary fibrous tumor in the ischiorectal fossa: a case report. AB - BACKGROUND: A solitary fibrous tumor (SFT) is a rare mesenchymal tumor that occurs mostly in pleural sites, and an SFT occurring in the ischiorectal fossa is extremely rare. Because of the rarity, there are few reports detailing an SFT in the ischiorectal fossa. CASE PRESENTATION: A pararectal tumor was incidentally found in a 42-year-old man during a routine medical examination. The patient had no symptoms and no previous medical history. In the physical examination, a smooth-margined and hard elastic mass was felt, and in a digital rectal examination, the rectal mucosa appeared normal. A computed tomography (CT) scan showed a 5-cm, well-defined, solid mass in the left ischiorectal fossa. Contrast enhanced CT in the early phase showed intense heterogeneous enhancement that persisted during the delayed phase. T2-weighted images of magnetic resonance imaging yielded heterogeneous intermediate and low signal intensity. Intense arterial enhancement suggested a hypervascular nature, and persistent delayed enhancement and low signal bands on T2-weighted images suggested a fibrous component of the mass. An SFT was suspected. Most SFTs are benign but have malignant potential. Our patient did not hope for surgery if the tumor was benign; therefore, an ultrasound-guided transperineal core needle biopsy was performed to decide on a treatment strategy. Microscopic examination showed tumor cells appearing as spindle and fibroblast-like cells within a collagenous stroma. Immunohistochemistry identified CD34 and vimentin, supporting the diagnosis of an SFT. The patient consented to excision of the mass. He was placed in a prone jackknife position, and the tumor was removed transperineally using a posterior approach (modified Kraske procedure). The levator ani muscle, external sphincter muscles, and rectum were not involved and separated from the tumor. The tumor was successfully resected en bloc with no complications. Five uneventful days post surgery, the patient was discharged. There was no local recurrence during the year following surgery. CONCLUSION: Imaging findings reflect the tissue characterization such as hypervascularity and fibrous nature of SFTs. We have presented a rare case of an SFT in the ischiorectal fossa with useful imaging findings for diagnosis, treatment strategy, and successful surgical removal using a posterior approach. PMID- 30284070 TI - Structural and functional abnormalities in iron-depleted heart. AB - Iron deficiency (ID) is a common and ominous comorbidity in heart failure (HF) and predicts worse outcomes, independently of the presence of anaemia. Accumulated data from animal models of systemic ID suggest that ID is associated with several functional and structural abnormalities of the heart. However, the exact role of myocardial iron deficiency irrespective of systemic ID and/or anaemia has been elusive. Recently, several transgenic models of cardiac-specific ID have been developed to investigate the influence of ID on cardiac tissue. In this review, we discuss structural and functional cardiac consequences of ID in these models and summarize data from clinical studies. Moreover, the beneficial effects of intravenous iron supplementation are specified. PMID- 30284071 TI - A qualitative study of Realtor knowledge, attitudes, and practices related to radon health effects: implications for comprehensive cancer control. AB - BACKGROUND: Lung cancer is the leading cause of cancer-related deaths in the United States, and radon exposure is the second leading risk factor. Fewer than 25% of existing U.S. homes have been tested for radon, and only 5-10% of new homes use some form of radon prevention. OBJECTIVE: This qualitative study sought to determine radon-related knowledge, attitudes, and practices among Realtors to inform cancer control activities at local and state levels. METHODS: We conducted focus groups with Realtors in four states to collect information about knowledge, attitudes, and practices regarding radon. RESULTS: Realtors reported obtaining information on radon in similar ways, being aware of radon and its characteristics, and dealing with radon issues as a normal part of home sales. Differences in attitudes toward testing varied across states. Realtors in states with radon policies generally expressed more positive attitudes toward testing than those in states without policies. Radon mitigation was identified as an added expense to buyers and sellers. Realtors cited concerns about the reliability and credibility of mitigation systems and installers. CONCLUSIONS: These findings suggest that attitudes and practices vary among Realtors and that additional educational resources about radon as a cancer risk factor may be beneficial. When comprehensive cancer control programs update their plans, they may want to add objectives, strategies, or activities to reduce radon exposure and prevent lung cancer. These activities could include partnering with Realtors to improve their knowledge, attitudes, and practices about radon, as well as developing and distributing radon educational resources. PMID- 30284072 TI - A new case of the pilomatrixoma rare in the preauricular region and review of series of cases. AB - Pilomatrixoma is considered a rare benign tumor arising from the hair follicle, most common in the head and neck region, but it is rarely diagnosed on a clinical basis. This report describes a new case of giant pilomatrixoma in a 36-year-old female patient. The nodule was localized in the preauricular area on the right side, appearing as a slow-growing, fixed, painless, with a hardened consistency, unusual giant (4.5 cm). A cone-beam computed tomography (CBCT) examination showed a slightly hyperdense lesion, and fine-needle aspiration cytology (FNAC) revealed peripheral blood and mononucleated inflammatory cells. After enucleation of lesion, a diagnosis of pilomatrixoma was confirmed. The differential diagnosis of pilomatrixoma is broad, because its characteristics also can be found in other lesions common to the head and neck. Thus, a lesion in the head and neck, adherent to the skin, and well demarcated, mainly in the young and in females, should be suspected as pilomatrixoma. PMID- 30284073 TI - Investigating the Relationship Between Climate and Valley Fever (Coccidioidomycosis). AB - Valley fever (coccidioidomycosis) is a disease caused by inhalation of spores from the soil-dwelling Coccidioides fungal species. The disease is endemic to semiarid areas in the western USA and parts of Central and South America. The region of interest for this study, Kern County, California, accounts for approximately 14% of the reported valley fever cases in the USA each year. It is hypothesized that the weather conditions that foster the growth and dispersal of the fungus influence the number of cases in the endemic area. This study uses regression-based analysis to model and assess the seasonal relationships between valley fever incidence and climatic variables including concurrent and lagged precipitation, temperature, Palmer Drought Severity Index, wind speed, and PM10 using data from 2000 to 2015. We find statistically significant links between disease incidence and climate conditions in Kern County, California. The best performing seasonal model explains up to 76% of the variability in fall valley fever incidence based on concurrent and antecedent climate conditions. Findings are consistent with previous studies, suggesting that antecedent precipitation is an important predictor of disease. The significant relationships found support the "grow and blow" hypothesis for climate-related coccidioidomycosis incidence risk that was originally developed for Arizona. PMID- 30284074 TI - Facile development of medium optimization for antibody production: implementation in spinner flask and hollow fiber reactor. AB - Most bio-industrial mammalian cells are cultured in serum-free media to achieve advantages, such as batch consistency, suspended growth, and simplified purification. The successful development of a serum-free medium could contribute to a reduction in the experimental variation, enhance cell productivity, and facilitate biopharmaceuticals production using the cell culture process. Commercial serum-free media are also becoming more and more popular. However, the cell line secrets its own recombinant product and has special nutritional requirements. How can the composition of the proprietary medium be adjusted to support the specific cell's metabolism and recombinant protein? This article uses statistical strategies to modify the commercial medium. A design of experiments is adopted to optimize the medium composition for the hybridoma cell in a serum free condition. The supplements of peptone, ferric citrate, and trace elements were chosen to study their impact on hybridoma growth and antibody production using the response surface methodology. The stimulatory effect of the developed formulation on hybridoma growth was confirmed by the steepest ascent path. The optimal medium stimulated the hybridoma growth and antibody production in three diverse systems: a static plate, an agitated spinner flask, and a hollow fiber reactor. The cells in the developed serum-free medium had a better antibody production as compared to that in the commercial medium in the hollow fiber reactor. Our results demonstrated that the facile optimization for medium and antibody production was successfully accomplished in the hybridoma cells. PMID- 30284075 TI - Effect of serum uric acid on cognition in patients with idiopathic REM sleep behavior disorder. AB - Idiopathic rapid eye movement sleep behavior disorder (iRBD) likely represents the prodromal stage of synucleinopathy. The present study investigated how levels of serum uric acid (UA) affect cognition and motor function in patients with iRBD. A total of 42 patients with iRBD and 45 healthy controls were included. All participants were given cognitive tests and motor assessments. Serum UA concentrations were measured. The patients were further divided into two groups (high or low UA) according to serum UA level. The level of serum UA was similar between the patients with iRBD and the healthy controls, whereas the patients showed impaired executive, memory, and visuospatial functions. The patients with low UA levels had longer durations of RBD. Lower scores involving attention, executive function, and language domain were also found in the patients with low UA, whereas the scores of the patients with high UA were similar to those of the healthy controls. Regarding memory domain, the low UA group had worse scores than the healthy controls, whereas the scores of high UA group fell between those of the low UA group and the healthy controls. Motor function was not affected in any of the groups. UA affects cognitive function but not motor function in patients with iRBD, which could contribute to its antioxidant and neuroprotective roles. PMID- 30284076 TI - Correlation between MCP-1-2518A/G polymorphism and the risk of Alzheimer's disease. AB - The -2518A/G polymorphism in monocyte chemotactic protein-1 (MCP-1) has been extensively investigated for association with Alzheimer's disease (AD); however, the results from different studies are inconsistent. The aim of this study was to draw an accurate conclusion of the association. All eligible case-control studies were searched in PubMed, Embase, Chinese National Knowledge Infrastructure, China Biological Medicine Databases, and Wanfang Databases. Eight case-control studies with a total of 2370 cases and 2413 controls were eligible to be included in this meta-analysis. The association was evaluated by calculating the odds ratios (ORs) with the corresponding 95% confidence intervals (CIs). Overall, there was no significant association between MCP-1-2518A/G polymorphism and AD risk in all genetic models (the allele model G vs. A: OR = 1.15, 95% CI 0.92-1.45, p = 0.22; the co-dominant model GG vs. AA: OR = 1.38, 95% CI 0.80-2.36, p = 0.25; the dominant model AG + GG vs. AA: OR = 1.14, 95% CI 0.89-1.46, p = 0.31; the recessive model GG vs. AG + AA: OR = 1.35, 95% CI 0.87-2.09, p = 0.18). In subgroup analysis by ethnicity, a significant difference was not detected in both Caucasians and Asians. In allele model (G vs. A), the required sample size of 31858 was calculated by applying trial sequential analysis. Cumulative z curve is always below the trial sequential monitoring boundary and is nominally statistically significant (Z = 1.96). A consistent result was obtained in other genetic models. In summary, the present meta-analysis suggests that MCP-1-2518A/G polymorphism may not be associated with genetic susceptibility of AD in general population, but the association remains indeterminate due to the insufficient evidence. PMID- 30284077 TI - Dogs and wolves do not differ in their inhibitory control abilities in a non social test battery. AB - Being able to inhibit certain behaviours is of clear advantage in various situations. In particular, it has been suggested that inhibitory control plays a role in problem-solving and cooperation. Interspecific differences in the capacity for inhibitory control have been attributed to social and ecological factors, while one additional factor, namely domestication, has received only little attention so far. Dogs are an interesting species to test the effects of socio-ecological factors and also the influence of domestication on inhibitory control abilities. While dogs might have been selected for enhanced inhibition skills during domestication, the predictions derived from their socio-ecological background are reversed. Wolves are cooperative hunters and breeders, while dogs predominately scavenge and raise their young alone, accordingly, it would be predicted that dogs show impaired inhibitory control abilities since they no longer rely on these coordinated actions. To test these hypotheses, we assessed inhibitory control abilities in dogs and wolves raised and kept under similar conditions. Moreover, considering the problem of context-specificity in inhibitory control measures, we employed a multiple-test-approach. In line with previous studies, we found that the single inhibition tests did not correlate with each other. Using an exploratory approach, we found three components that explained the variation of behaviours across tests: motivation, flexibility, and perseveration. Interestingly, these inhibition components did not differ between dogs and wolves, which contradicts the predictions based on their socio ecological backgrounds but also suggests that at least in tasks with minimal human influence, domestication did not affect dogs' inhibitory control abilities, thus raising questions in regard to the selection processes that might have affected inhibitory control abilities during the course of domestication. PMID- 30284078 TI - Prevalence of fibromyalgia in physicians in training: a cross-sectional study. AB - The prevalence of fibromyalgia (FM) in physicians in training (PIT) in Saudi Arabia is unknown. The aim of this study is to evaluate the prevalence of FM in PIT using different screening tools and factors associated with its development. We also aimed at evaluating the level of agreement and correlation between screening tools. This was a cross-sectional study conducted in a single academic institution. PIT were invited to fill three questionnaires: Fibromyalgia Rapid Screening tool (FirST), Fibromyalgia Survey Questionnaire (FSQ), and London Fibromyalgia Epidemiology Study Screening Questionnaire (LFESSQ). A total of 182 PIT completed the questionnaire. They were predominantly males (57.1%), single (56.0%), and at resident level (86.7%). The median age was 28 (interquartile range = 4). The average number of house-calls/month was 3.2 (SD = 2.3). The prevalence of FM using the FirST, FSQ, and LFESSQ was 6.0%, 8.2%, and 11.6%, respectively. Six (3.3%) fulfilled the three criteria concurrently. After adjusting for different variables using the FSQ, PIT with family history of FM had 23.6 times the odds for testing positive (95% CI = 3.12, 178.37), and every extra house-call/month was associated with a 50% increase in the odds for testing positive for FM (95% CI = 1.00, 2.25). Percent agreement between tools was high (all > 86%). Results for kappa coefficient showed moderate agreement between FSQ scores and each of FirST and LFESSQ. There was poor agreement between FirST and LFESSQ. FM is prevalent among PIT. There is a high percent agreement and poor to moderate correlation between the screening tools used. PMID- 30284079 TI - Physical activity levels after hip and knee joint replacement surgery: an observational study. AB - Usual care after hip or knee joint replacement does not adequately address the problem of low physical activity levels. We aimed to determine whether exercise delivered in a group setting in the early stage of outpatient rehabilitation influenced self-reported physical activity levels after hip or knee joint replacement. A case series of 79 participants referred to a 6-week outpatient orthopaedic exercise group after total hip or knee replacement were evaluated using the International Physical Activity Questionnaire (IPAQ) short form. Physical function was evaluated using Osteoarthritis Research Society International (OARSI) recommended performance-based tests (30 s Chair Stand Test, 40 m Fast Pace Walk Test, Stair Climb Test, Timed Up and Go Test, 6 Minute Walk Test). Measures were assessed at admission, discharge and 6 weeks after group discharge. Non-parametric analysis was conducted for IPAQ scores. Analysis of functional measures was conducted with linear mixed models with time modelled as a repeated measure. Standard multiple regression and correlation analysis were conducted. Fifty-four participants completed the study. Self-reported activity levels improved significantly at program discharge but not at 6-week follow-up. All performance-based measures improved significantly at program discharge. Fast paced walking and 6 Minute Walk Test measures continued to improve at 6-week follow-up. Group dynamics present in an outpatient rehabilitation exercise program may increase physical activity levels during group participation but not after group cessation. Performance in all functional measures improved at group discharge. PMID- 30284081 TI - Prevalence and Correlates of Reporting Difficulty Taking Antiretroviral Treatment Among HIV-Positive Illicit Drug Users in Vancouver, Canada: A Longitudinal Analysis. AB - People living with HIV who use illicit drugs continue to experience high rates of suboptimal treatment outcomes from antiretroviral therapy (ART). Although previous studies have identified important behavioural, social and structural barriers to ART adherence, the effects of patient-level factors have not been fully evaluated. Thus, we sought to investigate the prevalence and correlates of reporting ART was difficult to take among a cohort of illicit drug users in Vancouver, Canada. We accessed data from the AIDS Care Cohort to evaluate Exposure to Survival Services (ACCESS), an ongoing prospective cohort of HIV positive illicit drug users linked to comprehensive HIV clinical monitoring records. We used generalized linear mixed-effects modeling to identify factors longitudinally associated with periods in which individuals reported they found ART difficult to take. Between December 2005 and May 2014, 746 ART-exposed illicit drug users were recruited and contributed at least one study interview. Finding ART hard to take was reported by 209 (28.0%) participants at baseline, and 460 (61.7%) participants throughout the study period. Patients ingesting a greater daily pill count (adjusted odds ratio [AOR] = 1.12 per pill, 95% confidence interval [CI] 1.08-1.17) and experiencing barriers to healthcare (AOR = 1.64, 95% CI 1.34-2.01) were more likely to report difficulty taking ART. Patients less likely to report satisfaction with their HIV physician (AOR = 0.76, 95% CI 0.58-1.00) and achieve a non-detectable HIV viral load (AOR = 0.62, 95% CI 0.51-0.74) were more likely to report finding ART hard to take. In this community recruited cohort of ART-exposed illicit drug users, a substantial proportion reported they found HIV treatment hard to take, which was clearly linked to higher dissatisfaction with healthcare experiences and, most importantly, a lower likelihood of experiencing optimal virologic outcomes. Our findings reveal a number of opportunities to improve HIV treatment experiences and outcomes for people who use illicit drugs, including the use of treatment regimens with lower pill burdens, as well as reducing barriers to healthcare access. PMID- 30284080 TI - A phase II study of neoadjuvant chemotherapy with docetaxel, cisplatin, and S-1, followed by gastrectomy with D2 lymph node dissection for high-risk advanced gastric cancer: results of the KDOG1001 trial. AB - BACKGROUND: The prognosis of patients with gastric cancer with bulky node metastasis, linitis plastica (type 4), or large ulcero-invasive-type tumors (type 3) remains poor. We conducted a phase II study to evaluate the safety and efficacy of neoadjuvant chemotherapy with docetaxel, cisplatin, and S-1 (DCS) for establishing a new treatment modality that improves prognosis. METHODS: Patients received up to four 28-day cycles of DCS therapy (docetaxel at 40 mg/m2, cisplatin at 60 mg/m2 on day 1, and S-1 at 40 mg/m2 twice daily for 2 weeks) followed by gastrectomy with D2 nodal dissection. S-1 chemotherapy was administered for 1 year after surgical resection. The primary endpoint was the percentage of complete resections of the primary tumor with clear margins (R0 resection). The planned sample size was 40; this was calculated based on an expected R0 rate of 85% and a threshold R0 rate of 65%, with a one-sided alpha of 5% and a power of 90%. RESULTS: Between 2010 and 2017, 40 patients were enrolled. The R0 resection rate was 90%. The most common grade 3 or 4 adverse events during DCS therapy were leukocytopenia (27.5%), neutropenia (55.0%), and hyponatremia (22.5%). The most common grade 3 or 4 surgical morbidity was pancreatic fistula (12.5%); mortality was 0%. The pathological response rate was 57.5% with a grade 3 histological response rate of 8%. CONCLUSIONS: Neoadjuvant chemotherapy with DCS was feasible and showed a sufficient R0 resection rate. A future study with a sufficient follow-up period should confirm survival outcomes. PMID- 30284083 TI - Substance P and pain chronicity. AB - Substance P (SP) is a highly conserved member of the tachykinin peptide family that is widely expressed throughout the animal kingdom. The numerous members of the tachykinin peptide family are involved in a multitude of neuronal signaling pathways, mediating sensations and emotional responses (Steinhoff et al. in Physiol Rev 94:265-301, 2014). In contrast to receptors for classical transmitters, such as glutamate (Parsons et al. in Handb Exp Pharmacol 249-303, 2005), only a minority of neurons in certain brain areas express neurokinin receptors (NKRs) (Mantyh in J Clin Psychiatry 63:6-10, 2002). SP is also expressed by a variety of non-neuronal cell types such as microglia, as well as immune cells (Mashaghi et al. in Cell Mol Life Sci 73:4249-4264, 2016). SP is an 11-amino acid neuropeptide that preferentially activates the neurokinin-1 receptor (NK1R). It transmits nociceptive signals via primary afferent fibers to spinal and brainstem second-order neurons (Cao et al. in Nature 392:390-394, 1998). Compounds that inhibit SP's action are being investigated as potential drugs to relieve pain. More recently, SP and NKR have gained attention for their role in complex psychiatric processes. It is a key goal in the field of pain research to understand mechanisms involved in the transition between acute pain and chronic pain. The influence of emotional and cognitive inputs and feedbacks from different brain areas makes pain not only a perception but an experience (Zieglgansberger et al. in CNS Spectr 10:298-308, 2005; Trenkwaldner et al. Sleep Med 31:78-85, 2017). This review focuses on functional neuronal plasticity in spinal dorsal horn neurons as a major relay for nociceptive information. PMID- 30284085 TI - Cell biological profiling of reprogrammed cancer stem cell-like colon cancer cells maintained in culture. AB - Cancer stem cells (CSCs) are specific targets for therapeutic applications, but the rarity of CSCs within tumors makes the isolation of CSCs difficult. To overcome these problems, we generated CSCs in vitro using established reprogramming techniques. We transduced four previously established reprogramming factors, Oct3/4, Sox2, Klf4, and L-myc, into the colon cancer cell lines LoVo and OUMS-23, and investigated the biological characteristics of these lines. Tra-1 60+ cells were obtained from reprogrammed induced pluripotent stem (iPS) cell like colonies and showed CSC properties, including colony formation, maintenance of colonies by repeated passages, and feeder cell dependency, as well as increased expressions of CSC markers such as CD133 and ALDH1. The CSC-like cells showed increased chemoresistance to 5-fluorouracil and elevated tumorigenicity upon transplantation into kidneys of immune-deficient mice. These tumors shifted to a poorly differentiated stage with many atypical cells, cytoplasmic mucin, and focal papillary components, with demonstrated dedifferentiation. The principal component analysis from DNA microarrays showed that though both cell lines moved to iPS cells after reprogramming, they were not completely identical to iPS cells. Significantly elevated gene expression of Decorin and CD90 was observed in CSC-like cells. Together, these results show that reprogramming of cancer cells produced not pluripotent stem cells but CSC-like cells, and these findings will provide biological information about genuine CSCs and help establish new CSC targeted therapies. PMID- 30284086 TI - Forced expression of mouse progerin attenuates the osteoblast differentiation interrupting beta-catenin signal pathway in vitro. AB - Nuclear protein, lamin A, which is a component of inner membrane on nucleoplasm, plays a role in nuclear formation and cell differentiation. The expression of mutated lamin A, termed progerin, causes a rare genetic aging disorder, Hutchinson-Gilford progeria syndrome, which shows abnormal bone formation with the decrease in a number of osteoblasts and osteocytes. However, exact molecular mechanism how progerin exerts depressive effects on osteogenesis has not been fully understood. Here, we created mouse lamin A dC50 cDNA encoding progerin that lacks 50 amino acid residues at C-terminus, transfected it in mouse preosteoblast like MC3T3-E1 cells, and examined the changes in osteoblast phenotype. When lamin A dC50-expressed cells were cultured with differentiation-inductive medium, alkaline phosphatase (ALP) activity and mRNA levels of major osteoblast markers, type I collagen (Col1), bone sialoprotein (BSP), dentine matrix protein 1 (DMP1), and Runx2 were significantly decreased, and no mineralized nodules were detected as seen in control cells expressing empty vector. In the culture with mineralization-inductive medium, mRNA levels of BSP, osteocalcin, DMP1, Runx2, and osterix were strongly decreased parallel with loss of mineralization in lamin A dC50-expressed cells, while mineralized nodules appear at 21 days in control cells. Furthermore, lamin A dC50 expression was depressed nuclear localization of beta-catenin with the decrease of GSK-3beta phosphorylation level. These results suggest that lamin A dC50 depresses osteoblast differentiation in both early and late stages, and it negatively regulates beta-catenin activity interacting with GSK-3beta in cytoplasm. PMID- 30284087 TI - Generation of clinical-grade red blood cells from human umbilical cord blood mononuclear cells. AB - A xeno-free method for ex vivo generation of red blood cells (RBCs) is attempted in order to replicate for large-scale production and clinical applications. An efficient milieu was formulated using injectable drugs substituting the animal derived components in the culture medium. Unfractionated mononuclear cells isolated from human umbilical cord blood were used hypothesizing that the heterogeneous cell population could effectively contribute to erythroid cell generation. The strategy adopted includes a combination of erythropoietin and other injectable drugs under low oxygen levels, which resulted in an increase in the number of mature RBCs produced in vitro. The novelty in this study is the addition of supplements to the medium in a stage-specific manner for the differentiation of unfractionated umbilical cord blood mononuclear cells (MNCs) into erythropoietic lineage. The erythropoietic lineage was well established by day 21, wherein the mean cell count of RBCs was found to be 21.36 +/- 0.9 * 108 and further confirmed by an upregulated expression of CD235a+ specific to RBCs. The rationale was to have a simple method to produce erythroid cells from umbilical cord blood isolates in vitro by mitigating the effects of multiple erythroid-activating agents and batch to batch variability. PMID- 30284088 TI - Photobiomodulation effect on the proliferation of adipose tissue mesenchymal stem cells. AB - The use of mesenchymal stem cells (MSCs) in tissue engineering has been extensively investigated. The greater the proliferation of this cellular group, the greater the regenerative and healing capacity of the tissue to which they belong. In this context, photobiomodulation (PBM) is an efficient technique in proliferation of distinct cell types. However, its parameters and mode of action are still unclear and require further investigation. This study aimed to evaluate the PBM action with different energies in MSCs of adipose tissue (hASCs). We used hASCs, seeded in 24-well plates, with 3 * 104 cells per well, in culture media. We used a total of four experimental groups, one with hASCs and simulated PBM and three other groups, which received PBM irradiation at 24, 48, and 72 h, with a 660-nm laser and power of 40 mW and energy of 0.56, 1.96, and 5.04 J. We performed analyses of MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromidefor) and trypan blue to evaluate cell proliferation and viability, 1 h after PBM irradiation. Software Graph PadPrism 7.0 was used. Intergroup comparisons were performed with ANOVA two-way and we used the Tukey post hoc test. Mitochondrial activity evaluated by MTT revealed the statistical difference in the first 24 h for group with more high energy when compared to control group; and in the 72 h for two irradiated groups when compared to the control group. The trypan blue test showed significant differences at the end of the experiment for two irradiated groups LG1 (4.52 * 104 +/- 0.2) and LG2 (4.85 * 104 +/- 0.8), when compared to the control group (1.87 * 104 +/- 0.7). Both tests failed to be statistically different at the end of the experiment for groups LG1 and LG2 and observed a reduction in cellular mitochondrial growth and activity for group LG3. We conclude that PBM with energy close to 0.56 and 1.96 J promote proliferation of hASCs, and higher energy, such as 5.04 J, can be harmful. PMID- 30284084 TI - Basement membranes in the cornea and other organs that commonly develop fibrosis. AB - Basement membranes are thin connective tissue structures composed of organ specific assemblages of collagens, laminins, proteoglycan-like perlecan, nidogens, and other components. Traditionally, basement membranes are thought of as structures which primarily function to anchor epithelial, endothelial, or parenchymal cells to underlying connective tissues. While this role is important, other functions such as the modulation of growth factors and cytokines that regulate cell proliferation, migration, differentiation, and fibrosis are equally important. An example of this is the critical role of both the epithelial basement membrane and Descemet's basement membrane in the cornea in modulating myofibroblast development and fibrosis, as well as myofibroblast apoptosis and the resolution of fibrosis. This article compares the ultrastructure and functions of key basement membranes in several organs to illustrate the variability and importance of these structures in organs that commonly develop fibrosis. PMID- 30284090 TI - Clinical Predictors of Delayed Discharges in Inpatient Mental Health Settings Across Ontario. AB - Delayed discharges constitute an ongoing issue in psychiatric facilities. This study examined clinical predictors of 30-day delayed discharges in all designated inpatient mental health units within Ontario, Canada. Data for 76,184 inpatient episodes were obtained from 68 psychiatric facilities between 2011 and 2013. Risk factors for delayed discharges were analyzed using multivariate logistic regression. Indicators of functional, social, and cognitive impairment positively predicted delayed discharges, while symptoms of mental illness were inversely related. Policy makers and mental health care practitioners may utilize early predictors of delayed discharges to introduce treatment interventions and policies that reduce the risk of delays in mental health settings. PMID- 30284089 TI - Shared decision making in pharmacotherapy decisions, perceived by patients with bipolar disorder. AB - BACKGROUND: Shared decision making has been promoted as standard care, but there has been debate on the possible types. On the one hand, there is a more 'instrumental'/objective approach focused on the exchange of information, but an 'interpersonal'/subjective patient involvement has been suggested as well. In this study we aim to investigate this further by assessing both actual and perceived patient involvement in medical decisions. METHODS: Eighty-one consultations between patients with bipolar disorder and their clinicians were observed and scored using the OPTION scale. Afterwards, the patients' experienced involvement was explored with the SDM-Q-9. Furthermore, several patient characteristics were gathered. Correlations between the scores were examined. RESULTS: The clinicians scored on average 34.6 points on the OPTION scale. In contrast, patients scored on average 77.5 points on the SDM-Q-9, suggesting that patients felt more involved in the consultation than was observable. CONCLUSION: Our patients with bipolar disorder feel involved in pharmacotherapy decisions, but this is not scored in objective observations. Our data suggest that there are implicit, interpersonal aspects of patient involvement in shared decision making, a concept that deserves further attention and conceptualisation. PMID- 30284091 TI - MP-3 measurement of retinal sensitivity in macular hole area and its predictive value on visual prognosis. AB - PURPOSE: To explore a measuring method for retinal sensitivity in macular hole area by Microperimeter-3 (MP-3) and evaluate its predictive value on visual prognosis. METHODS: This was a case series study including 44 eyes of 44 patients with idiopathic macular hole. Retinal sensitivity inside and 0.5 degree outside the macular hole margin was measured, and its mean value was defined as macular hole sensitivity (MHS). Best-corrected visual acuity (BCVA), minimum diameter of macular hole (MD), IS/OS defect diameter, retinal sensitivity in 8 degrees and 2 degrees were also recorded preoperatively and 4 months after operation. RESULTS: All macular holes were closed after surgery. BCVA was significantly improved from 1.06 +/- 0.39 at baseline to 0.31 +/- 0.24 at 4 months postoperatively (P < 0.001). Meanwhile, MHS was also significantly improved from 12.02 +/- 3.74 dB at baseline to 20.72 +/- 4.00 dB at 4 months postoperatively (P < 0.001). MD, preoperative IS/OS defect diameter, preoperative BCVA, preoperative retinal sensitivity in 8 degrees and 2 degrees, and preoperative MHS were all correlated with postoperative BCVA at 4 months, but only preoperative MHS showed liner relationships to postoperative BCVA at 4 months by multivariate stepwise linear analysis. CONCLUSIONS: Macular hole sensitivity by MP-3 could reflect the change of central retinal function after successful macular hole surgery. Compared to preoperative retinal sensitivity in 8 degrees and 2 degrees, preoperative macular hole sensitivity is a better predictor for visual prognosis. PMID- 30284092 TI - Surgical outcomes of 27-gauge and 25-gauge vitrectomy day surgery for proliferative diabetic retinopathy. AB - PURPOSE: To compare postoperative outcomes of 27-gauge (G) and 25-G vitrectomy conducted as day surgery for proliferative diabetic retinopathy (PDR). METHODS: One hundred eighty-five consecutive PDR patients (185 eyes) who underwent primary vitrectomy (27-G in 64 eyes, 25-G in 121 eyes) were analyzed. RESULTS: The 27-G and 25-G groups did not differ significantly in preoperative Early Treatment Diabetic Retinopathy Study (ETDRS) score, age, or preoperative intraocular pressure. The proportions of simultaneous cataract surgery (27-G vs. 25-G: 59.4% vs. 62.4%) and air-filled eyes (76.6% vs. 85.1%) were not significantly different between two groups. Both groups showed significant improvement in ETDRS score at postoperative 1, 3, and 6 months (all, P < 0.0001). Mean gain in ETDRS score from baseline was apparently better in 27-G group than in 25-G group at 1, 3, and 6 months, but there were no significant differences (1 month: 20.3 vs. 13.1 letters, P = 0.0703; 3 months: 22.9 vs. 17.5 letters, P = 0.1561; 6 months: 24.3 vs. 19.3 letters, P = 0.3313). Operation time was apparently longer for 27-G vitrectomy, but there was no significant difference (54.0 vs. 51.1 min, P = 0.3676). The same was observed for postoperative intraocular pressure at postoperative day 1 (19.7 vs. 18.1 mmHg, P = 0.1353). Incidence of postoperative retinal detachment (1.6% vs. 0.8%) and reoperation due to vitreous hemorrhage (6.3% vs. 6.6%) was not different between two groups. CONCLUSIONS: The 27G system is as safe and as useful as the 25G system when used for PDR and can be expected to achieve earlier recovery of postoperative visual acuity. PMID- 30284094 TI - Do Home-Based Psychiatric Services for Patients in Medico-Social Institutions Reduce Hospitalizations? Pre-Post Evaluation of a French Psychiatric Mobile Team. AB - World Health Organization recommends the implementation of alternatives to full time hospitalizations. Psychiatric home-care has known a worldwide development in the last 20 years. The psychiatric mobile team for social and medico-social institutions in Saint-Etienne, France, (Equipe mobile d'intervention en etablissements Sociaux et Medico-sociaux, ESMS) aims to support professionals from medico-social housing institutions (MSHI) in order to maintain people in housing. The objective of the study was to evaluate the efficiency of home-based interventions to reduce hospitalizations and improve collaboration between psychiatric hospital facilities and MSHI. We used a pre-post study design. A same cohort of patients living in a MSHI one year before intervention and one year after implementation of the ESMS was studied. Hospitalizations were compared between the two periods. A survey was conducted for qualitative evaluation among professionals in MHSI. Sixty-three patients were included. Most patients suffered from psychotic disorders (71%). We found a significant decrease in the mean number of admissions per year from 2,06 to 1,48 (Wilcoxon signed rank test; df64; p = 0,01). Mobile-team interventions included answering phone calls, home visits, coordination meetings, or clinical interviews with patients in inpatient and outpatient services, with an average of 9,3 interventions per patient (SD = 11,4). ESMS was evaluated as "essential" for 73% of 11 professionals from MSHI who answered the questionnaire in May 2017. Assertive Community Treatment and Crisis Resolution Teams are the most studied home-care models in psychiatry. Our results tend to show the efficiency of mobile-team interventions in MSHI, to enhance partnerships. PMID- 30284093 TI - Improving the fluorometric determination of the cancer biomarker 8-hydroxy-2' deoxyguanosine by using a 3D DNA nanomachine. AB - The authors describe a fluorometric method for improving the determination of the cancer biomarker 8-hydroxy-2'-deoxyguanosine (8-OHdG). A nicking endonuclease (NEase)-powered 3-D DNA nanomachine was constructed by assembling hundreds of carboxyfluorescein-labeled single strand oligonucleotides (acting as signal reporter) and tens of swing arms (acting as single-foot DNA walkers) on a gold nanoparticle (AuNP). The activity of this DNA nanomachine was controlled by introducing the protecting oligonucleotides. In the presence of aptamer against 8 OHdG, the protecting oligonucleotides are removed from the swing arms by toehold mediated strand displacement reaction. In the next step, detached DNA walker hybridizes to the labelled DNA so that the DNA nanomachine becomes activated. Special sequences of signal reporter in the formed duplex can be recognized and cleaved by NEase. As a result, the DNA walker autonomously and progressively moves along the surface of the AuNP, thereby releasing hundreds of signal reporters and causing a rapid increase in green fluorescence. This 3-D nanomachine is highly efficient because one aptamer can release hundreds of signal reporters. These unique properties allowed for the construction of a DNA nanomachine-based method for sensitively detecting 8-OHdG in concentrations as low as 4 pM. This is three orders of magnitude lower compared to previously reported methods. Graphical abstract Schematic of a fluorometric method for determination of the cancer biomarker 8-hydroxy-2'-deoxyguanosine. A nicking endonuclease powered 3D-DNA nanomachine was used to improve the sensitivity. Limit of detection is three orders of magnitude lower than reported methods. PMID- 30284095 TI - Introducing Mother Baby Connections: a model of intensive perinatal mental health outpatient programming. AB - Perinatal mental health problems, experienced by 15-20% of women, are a significant public health issue associated with adverse effects among childbearing women; yet only 20-25% receive adequate treatment. There has been a recent proliferation of intensive perinatal day treatment programs in the United States. To meet this need in the greater Philadelphia area, we introduce Mother Baby Connections (MBC), an innovative interdisciplinary, attachment-focused, intensive, outpatient perinatal mental health program recently launched at Drexel University. The purpose of this paper is to (1) present an overview of MBC, its theoretical framework for services, and its evidence-based components, highlighting the unique factors that differentiate this program from traditional outpatient treatment, and (2) present clinical outcome data utilizing scores from reliable and valid scales, including enrollment to discharge outcomes from 20 months of MBC operation. In sum, outcomes for 20 predominantly minority women with complete measures showed significant improvements in maternal depression symptom severity, maternal functioning, birth trauma symptoms, perceived stress, parenting stress, and emotional regulation. Effect sizes were medium to large (i.e., 0.42-2.00). We conclude that MBC is a viable model for tailored intensive outpatient treatment to foster maternal mental health and functioning during the perinatal period. PMID- 30284096 TI - In vitro culture supplementation of EGF for improving the survival of equine preantral follicles. AB - Folliculogenesis is a process of development and maturation of the ovarian follicles, being essential for the maintenance of fertility. In in vivo conditions, 99.9% of the follicles of an ovary do not ovulate and undergo atresia. In order to minimize this loss and to clarify the existing mechanisms, a technique was developed that allows for the in vitro follicular development. The objective of this study was to evaluate the effects of different epidermal growth factor (EGF) concentrations on the in vitro culturing of equine preantral follicles. Ovaries (n = 10) were collected from a local slaughterhouse of mares in seasonal anestrus, washed with 70% alcohol and PBS, and transported. The inner portion of the ovary was divided into 11 fragments of approximately 3 * 3 * 1 mm. A fragment of each ovary was immediately fixed in Bouin (control group). The remaining 10 fragments were individually cultured for 2 and 6 d. The medium was supplemented with different concentrations of EGF (0, 10, 50, 100, and 200 ng/mL). After cultivation, the fragments were processed and classified according to the developmental stage and morphology. In total, 1065 slides containing 6105 tissue sections were evaluated. Within 2 d of culture, there was a higher proportion of intact follicles at the EGF concentrations of 0 and 100 ng/mL (p > 0.05). After 6 d of culture, only the EGF concentration of 100 ng/mL demonstrated a difference when compared to the other treatments (0, 10, 50 and 200 ng/mL of EGF, p > 0.05). There was follicular development after 2 d at all EGF concentrations. Thus, we suggest that EGF promotes follicular survival in equines at a concentration of 100 ng/mL in in vitro cultures of ovarian fragments for 2 d. In addition, we suggest that EGF promotes follicular survival in equines at a concentration of 100 ng/mL in situ cultivation. PMID- 30284097 TI - Effects of continuous positive airway pressure in patients at high risk of obstructive sleep apnea during propofol sedation after spinal anesthesia. AB - In patients with obstructive sleep apnea, short-term use of a continuous positive airway pressure mask improves oxygenation, decreases the apnea-hypopnea index, and reduces hemodynamic instability. In this study, we investigated the effects of use of a continuous positive airway pressure mask in patients at high risk of obstructive sleep apnea during propofol sedation after spinal anesthesia. Forty patients who underwent propofol sedation after spinal anesthesia for transurethral bladder or prostate resection with a STOP-Bang score of 3 or more were enrolled in this study. Patients were randomly divided into two groups: a simple oxygen mask group (n = 20) and a continuous positive airway pressure mask group (n = 20). After spinal anesthesia, propofol was injected at a target concentration of 1.3 mcg/ml via a target concentration control injector. ApneaLinkTM was applied to all patients. Patients in the simple oxygen mask group were administered oxygen at a rate of 6 L/min through a simple facial mask. Patients in the CPAP mask group were connected to a pressurizer, and oxygen (6 L/min, 5-15 cm H2O) was administered. Blood pressure, heart rate, respiratory rate, and oxygen saturation were recorded preoperatively, after spinal anesthesia, and every 5 min after the injection of propofol to observe hemodynamic changes. Apnea-hypopnea index was estimated using ApneaLinkTM. There were no significant differences in hemodynamic changes between the two groups. Apnea-hypopnea index was significantly reduced in the continuous positive airway pressure mask group compared to the simple facial mask group. Application of a continuous positive airway pressure mask in a patient at high risk of obstructive sleep apnea can lower the incidence of obstructive sleep apnea during sedation without a significant effect on hemodynamic stability. PMID- 30284098 TI - Non-invasive real-time autonomic function characterization during surgery via continuous Poincare quantification of heart rate variability. AB - Heart rate variability (HRV) provides an excellent proxy for monitoring of autonomic function, but the clinical utility of such characterization has not been investigated. In a clinical setting, the baseline autonomic function can reflect ability to adapt to stressors such as anesthesia. No monitoring tool has yet been developed that is able to track changes in HRV in real time. This study is a proof-of-concept for a non-invasive, real-time monitoring model for autonomic function via continuous Poincare quantification of HRV dynamics. Anonymized heart rate data of 18 healthy individuals (18-45 years) undergoing minor procedures and 18 healthy controls (21-35 years) were analyzed. Patients underwent propofol and fentanyl anesthesia, and controls were at rest. Continuous heart rate monitoring was carried out from before aesthetic induction to the end of the surgical procedure. HRV components (sympathetic and parasympathetic) were extracted and analyzed using Poincare quantification, and a real-time assessment tool was developed. In the patient group, a significant decrease in the sympathetic and parasympathetic components of HRV was observed following anesthesia (SD1: p = 0.019; SD2: p = 0.00027). No corresponding change in HRV was observed in controls. HRV parameters were modelled into a real-time graph. Using the monitoring technique developed, autonomic changes could be successfully visualized in real-time. This could provide the basis for a novel, fast and non invasive method of autonomic assessment that can be delivered at the point of care. PMID- 30284099 TI - Identification of C-Terminal Binding Protein 1 as a Novel NMDA Receptor Interactor. AB - A new N-methyl D aspartate neurotransmitter receptor interacting protein has been identified by yeast two-hybrid screening of a mouse brain cDNA library. C terminal binding protein 1 (CtBP1) was shown to associate with the intracellular C-terminal regions of the N-methyl D aspartate receptor subunits GluN2A and GluN2D but not with GluN1-1a cytoplasmic C-terminal region. In yeast mating assays using a series of GluN2A C-terminal truncations, it was demonstrated that the CtBP1 binding domain was localized to GluN2A 1157-1382. The GluN2A binding domain was identified to lie within the CtBP1 161-224 region. CtBP1 co immunoprecipitated with assembled GluN1/GluN2A receptors expressed in mammalian cells and also, in detergent extracts of adult mouse brain. Co-expression of CtBP1 with GluN1/GluN2A resulted in a significant decrease in receptor cell surface expression. The family of C-terminal binding proteins function primarily as transcriptional co-repressors. However, they are also known to modulate intracellular membrane trafficking mechanisms. Thus the results reported herein describe a putative role for CtBP1 in the regulation of cell surface N-methyl D aspartate receptor expression. PMID- 30284100 TI - Screening and diagnosis of oral cancer: a critical quality appraisal of clinical guidelines. AB - OBJECTIVES: To assess the quality of clinical practice guidelines (CPGs) on screening and diagnosis of oral cancer and to describe the characteristics of their recommendations. MATERIALS AND METHODS: We systematically searched EMBASE, MEDLINE, CPG' websites, and dentistry and oncology scientific societies to identify CPGs that were related to screening and diagnosis of oral cancer. The quality of selected CPGs was independently assessed by four appraisers using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument. The inter-appraiser agreement was assessed. We performed a descriptive analysis of the recommendations included in the selected CPGs. RESULTS: Eight CPGs were selected. The overall agreement among reviewers was considered very good (ICC: 0.823; 95% CI: 0.777-0.861). The median scores of the six AGREE II domains were as follows: "scope and purpose" 97.9% (IQR: 96.2-100.0%); "stakeholder involvement" 86.1% (IQR: 69.8-93.1%); "rigor of development" 75.3% (IQR: 64.2 94.3%); "clarity of presentation" 91.7% (IQR: 82.6-94.4%); "applicability" 53.1% (IQR: 19.3-74.2%); and "editorial independence" 83.3% (IQR: 67.2-93.8%). Four CPGs were assessed as "recommended", four "recommended with modifications", and none "not recommended". Twenty-three recommendations were provided, mostly with a low or very low level of evidence. CONCLUSION: The methodological quality of CPGs on screening and diagnosis of oral cancer is moderate. The "applicability" domain scored the lowest. Most recommendations were based on a low o very low level of evidence. CLINICAL RELEVANCE: Greater efforts are needed to provide healthcare based on high-quality evidence-based CPGs in this field. PMID- 30284101 TI - Effect of anaerobic cure of self-etch adhesive on degree of conversion and shear bond strength. AB - OBJECTIVE: The main aim was to evaluate the effect of postponing the curing of the adhesive layer until the first layer of composite resin is applied-hereby oxygen-inhibited layer (OIL) formation and its detrimental effect on the degree of conversion (DC) of self-etch adhesives should be prevented. For this purpose, the degree of conversion and shear bond strength of four current market self-etch adhesives were evaluated, assessing the effect of curing the adhesives anaerobically and then under two different thicknesses of composite resin, and compare this to the samples cured alone and in air. MATERIALS AND METHODS: The degrees of conversion were obtained by attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy, after the samples were prepared on a glass slide. The samples were either light-cured in air or anaerobically under a clear matrix strip alone, under 2 mm of cured composite resin or under 4 mm of cured composite resin. To determine the shear bond strength (SBS), extracted molars were halved and set in acrylic. Prefabricated cured cylinders of composite resin (TPH 3, 2.4 mm in diameter) of two different lengths are placed over the adhesives under the following conditions: light-cured conventionally (2-mm-long cylinder) and light-cured anaerobically under the uncured end of the piece of composite resin (using both 2- and 4-mm-long cylinders as separate treatments). After another incubation for 24 h at 37 degrees C, the samples were subjected to shearing using the Bisco Shear Bond Strength Tester. RESULTS: The degree of conversion of the one-step self-etch adhesives was not statistically different when cured anaerobically under a clear matrix strip or cured anaerobically under 2 mm of composite resin. These results were greater than those cured under 4 mm. Shear bond strength between samples cured in air and anaerobically were similar under 2 mm of composite resin tubes, while those cured anaerobically under 4 mm of resin showed lower shear bond strength. CONCLUSION: When cured anaerobically, one-step self-etch adhesives show a greater degree of conversion and no significant difference in degree of conversion and shear bond strength when compared to those cured in air under the same thickness of composite resin. CLINICAL RELEVANCE: The results obtained from DC and SBS analysis show promise in placing the uncured adhesive under the composite resin and curing both the adhesive and restoration material simultaneously. PMID- 30284102 TI - Comparison of linear and volumetric measurements obtained from periodontal defects by using cone beam-CT and micro-CT: an in vitro study. AB - OBJECTIVES: To assess linear and volumetric measurement accuracy of periodontal defects (class 2 furcation, fenestration, dehiscence, and three-wall intrabony defect) by using CBCT and micro-CT images obtained at different voxel sizes. MATERIAL AND METHODS: We created 66 periodontal defects in human dry mandibles. Images of teeth with defects were taken by Planmeca Promox 3D Max (CBCT) at voxel sizes of 0.2 and 0.075 mm and super-argus PET/CT (micro-CT) at voxel sizes of 0.12 and 0.06 mm. All defects were then linearly (depth, width, and height) and volumetrically measured by 3D-DOCTOR software. Differences between voxels were assessed by Wilcoxon signed rank test. Bland-Altman limits of agreement and ICCs were calculated to assess agreement between the methods. Significance was set at p < 0.05. RESULTS: Volumes measured by micro-CT (0.12-0.06 mm) were higher than those of CBCT (0.2-0.075 mm) measurements regardless of the voxel size. ICC between micro CT and CBCT methods was found to be statistically significant for all types of defects in terms of volume (p < 0.001), height (p < 0.05), width (p < 0.001), and depth measurements (p < 0.001). CONCLUSION: CBCT provides useful information regarding linear and volumetric measurement of periodontal defects in vitro. CLINICAL RELEVANCE: Size and volume of periodontal defects may play an important role in the determination of the most appropriate treatment plan and disease prognosis along with outcome assessment. PMID- 30284103 TI - Supplementation of biotin to sperm preparation medium enhances fertilizing ability of spermatozoa and improves preimplantation embryo development. AB - PURPOSE: Motility of spermatozoa helps not only in planning the type of infertility treatment but also directly reflects the success rate in assisted reproductive technology (ART). Previously, biotin, a water-soluble vitamin, has been shown to increase the motility and longevity of cryopreserved human spermatozoa. The present study was designed to understand the molecular basis of the beneficial effects of presence of biotin in sperm wash medium on early embryo development. METHODS: The effect biotin supplementation to sperm wash medium on the sperm parameters were assessed in swim-up fraction of normozoospermic and asthenozoospermic ejaculates collected from infertile men. Fertilization and early embryo development was studied using Swiss albino mice. RESULTS: Even though both biotin and pentoxifylline (PTX) enhanced the motility of spermatozoa from normozoospermic and asthenozoospermic samples, biotin group exhibited higher in vitro survival. Using mouse model, we observed that presence of biotin or PTX in sperm wash medium improved the fertilization rate and blastocyst rate compared to control. Blastocysts from these groups had significantly higher total cell number (P < 0.01) and lower apoptotic index. In silico target prediction revealed that GTPase HRas (HRas), tyrosine-protein phosphatase nonreceptor type 1 (PTP1B), and glucokinase are the probable targets for biotin. Solution-state Nuclear Magnetic Resonance (NMR) studies confirmed that biotin interacts both with human HRas and PTP1B. CONCLUSION: Our results indicate that presence of biotin in sperm wash medium can improve the fertilization potential and preimplantation embryo development and can be considered as a safe alternate to PTX. PMID- 30284104 TI - Increased frequency of impaired fasting glucose and isolated systolic hypertension in Paget's disease of bone. AB - PURPOSE: Scanty data about glucose metabolism and hypertension have been reported in Paget's disease of bone (PDB) to be related with increased cardiovascular mortality. The aim of the present study was to evaluate glucose and blood pressure levels in PDB, looking for their association with disease severity. METHODS: We performed an observational cross-sectional study in 54 patients with PDB and 54 age, sex and BMI-matched controls. Glucose and blood pressure levels and parameters of bone and mineral metabolism were assessed. RESULTS: Patients with PDB showed increased glucose levels (6.3 +/- 1.7 vs 5.3 +/- 1.4 mmol/l, p < 0.001) and prevalence of impaired fasting glucose (14.8%, 5.3-24.3 vs 1.9%, 0 5.4, p < 0.02) as well as enhanced systolic blood pressure (145.9 +/- 21.3 vs 132.9 +/- 18.9 mmHg, p < 0.005), pulse pressure (69.6 +/- 20.0 vs 56.0 +/- 16.9 mmHg, p < 0.01) and prevalence of isolated systolic hypertension (46.3%, 33.0 59.6 vs 16.7%, 6.7-26.6, p < 0.003) in comparison to controls. Moreover, we found a positive association of (1) glucose levels with ionized calcium and bone alkaline phosphatase; (2) both systolic and pulse pressure with total and bone alkaline phosphatase (p < 0.05). By multiple linear regression analysis (R2 = 0.26; p < 0.05) serum ionized calcium correlated with glucose levels (beta = 0.44; p < 0.04), after adjusting for age and BMI. CONCLUSIONS: Our study shows increased fasting glucose, systolic and pulse pressure levels as well as enhanced prevalence of impaired fasting glucose and isolated systolic hypertension in PDB, potentially accounting for increased cardiovascular mortality. Furthermore, our findings suggest high serum calcium and/or increased bone alkaline phosphatase as a link between PDB and cardio-metabolic disorders. PMID- 30284105 TI - Grape seed proanthocyanidin extract and insulin prevents cognitive decline in type 1 diabetic rat by impacting Bcl-2 and Bax in the prefrontal cortex. AB - It is frequently accepted that grape seed proanthocyanidins (GSPs) are efficient antioxidants and beneficial in improving cognitive functions. However, diabetes (T1DM)-associated declines in learning and memory and the possibilities of GSPs in overcoming this loss needs to be examined. The present study was designed to examine the correlation, if one exists, between cognitive behavior and neuronal survival in the prefrontal cortex (PFC) in streptozotocin (STZ)-induced diabetic Wistar rats as well as to further clarify whether the correlation exists. Also this study aimed to determine whether neurological structural changes in the PFC and pancreatic beta-cells can be restored by grape seed proanthocyanidin extract (GSPE). At the end of 8 weeks, cognitive tests that rats given supplementation of GSPE and insulin had greater improvement in their spatial learning and memory skills and improved neuronal survival in the PFC and pancreatic beta-cells compared to rats supplemented with either insulin or GSPE alone. Expression of Bax in the PFC was increased in the diabetic rats while Bcl-2 expression was decreased, and GSPE and insulin treatment reversed the expression of apoptotic proteins. Our findings on GSPE, a natural product, as a form of adjuvant therapy together with insulin treatment is suggestive of the existence of synergism between the two in attenuating diabetic complications in the pancreas and PFC.

PMID- 30284107 TI - Design, synthesis and in vitro evaluation of a Dopa-organoboron compound that acts as a bladder relaxant through non-catecholamine receptors. AB - Bladder relaxation through drug administration is an interesting topic in medicinal and combinatorial chemistry. In fact, compounds targeting catecholamine receptors [dopamine receptors and beta-adrenergic receptors (betaAR) expressed in the bladder] are among the compounds commonly employed for this purpose. In particular, recent investigations have tended to focus on the beta3-adrenoceptor (beta3AR) as a target in the treatment of urinary incontinence and other disorders. However, organoboron compounds have been suggested as potent and efficient agents on these drug targets. In this work, through a docking study, we identified the parameters that induce a theoretical improvement in the affinity and activity of the organoboron compounds on the catecholamine receptors expressed in the bladder. Then, the identified potential drug, a boron-containing dopa-derivative named DPBX-L-Dopa, was synthesized and characterized. This compound induces a relaxation on the smooth muscle of the rat bladder, behaving as a weak relaxant compared to isoproterenol but with similar efficacy to BRL377, a selective beta3AR agonist. However, unexpectedly, this effect was not blocked by propranolol or haloperidol at the concentrations at which they are able to block the catecholamine receptors in bladder tissue. In view of these results, the effect of DPBX-L-Dopa compound on the alpha 1 adrenergic receptors (alpha1AR) of aorta of the rats was also explored; however, no response of the tissue to this compound was obtained. The possible mechanisms of the action of this compound were explored and are discussed further. PMID- 30284108 TI - Inhibitory Potential against Digestive Enzymes Linked to Obesity and Type 2 Diabetes and Content of Bioactive Compounds in 20 Cultivars of the Peach Fruit Grown in Poland. AB - The presented study provides important insights on the health properties of Prunus persica fruit related to their polyphenol and carotenoid profiles, antioxidant capacity and in vitro potential to inhibit enzymes relevant to type 2 diabetes (alpha-amylase, alpha-glucosidase) and obesity (pancreatic lipase) management. Such results have not been published so far. The study showed substantial differences in the chemical composition of peach fruit depending on the cultivar. At the same time, it demonstrated some common features of selected cultivars - the varieties with light flesh ('Spring Time'; 'Madison') were characterized by a high content of phenolic acids and flavonols, thus exhibiting high activity against alpha-amylase, while the yellow varieties with high content of carotenoids ('Harrow Diamond'; 'Harrow Beauty') showed high inhibitory activity toward porcine pancreatic lipase. Finally, it has been shown that peach fruit is an interesting raw material with a varied chemical composition and nutritional value, especially with high inhibitory potential against digestive enzymes linked to obesity and type 2 diabetes, strongly determined by the cultivar. PMID- 30284110 TI - Enhanced Confinement of Terahertz Surface Plasmon Polaritons in Bulk Dirac Semimetal-Insulator-Metal Waveguides. AB - A subwavelength terahertz plasmonic waveguide based on bulk Dirac semimetal (BDS) insulator-metal (BIM) structure is investigated, which indicates that there is an optimized frequency range with the better confinement as well as lower loss. A broadband mode confinement up to lambda0/15 with a relatively low loss of 1.0 dB/lambda0 can be achieved. We also show that two silicon ribbons introduced into the BIM waveguide can form a dynamically tunable filter tailoring terahertz surface plasmon polaritons in deep-subwavelength scale, which can be further exploited for the design of ultra-compact THz plasmonic devices with dynamical tunability. Our results may also provide potential applications in optical filtering. PMID- 30284111 TI - A PPy/ZnO functional interlayer to enhance electrochemical performance of lithium/sulfur batteries. AB - To enhance the electrochemical performance of the lithium/sulfur batteries, a novel interlayer was prepared by coating the slurry of PPy/ZnO composite onto the surface of a separator. Owing to a three-dimensional hierarchical network structure, PPy/ZnO composite serves as a polysulfide diffusion absorbent that can intercept the migrating soluble polysulfides to enhance the electrochemical performance of the Li/S batteries. The specific capacity of the cell with PPy/ZnO interlayer remained at 579 mAh g-1 after 100 cycles at 0.2 C. This interlayer can provide novel avenues for the commercial applications of Li/S batteries. PMID- 30284109 TI - Nutraceutical, Physicochemical, and Sensory Properties of Blue Corn polvorones, a Traditional Flour-Based Confectionery. AB - Blue corn is an anthocyanin-rich material that can be used in the preparation of baking products. The aim of this work was to evaluate the physicochemical, nutraceutical, and sensory properties of polvorones (a traditional flour-based confectionery) made with whole blue-corn flour. All samples showed similar bromatological composition, but polvorones from whole blue-corn flour had a higher phenolics (837.1 mg gallic acid/kg) and anthocyanins (373.0 mg cyanidin-3 glucoside/kg) content, which exerted an influence on their higher antioxidant activity compared with wheat flour-based laboratory and commercial samples. The transformation of raw blue-corn flour into polvorones produced the degradation of some acylated anthocyanins into non-acylated forms. The substitution of wheat flour with whole blue-corn flour enhanced overall acceptability, as well as the color and flavor of polvorones. Our findings demonstrated that it is possible to use whole blue corn in the formulation of polvorones with more health beneficial properties and better consumer acceptability than refined wheat products. PMID- 30284112 TI - Analysis of the regulatory mechanism of deoxynivalenol production using omics. AB - Fusarium species are plant pathogens that produce various mycotoxins. Here, the regulatory mechanism of deoxynivalenol production in Fusarium asiaticum was analyzed using proteomic, metabolomic and transcriptomic methods. F. asiaticum was induced to produce deoxynivalenol by adding agmatine to the culture medium. Subsequently, metabolites of the glycolysis system were increased but mRNAs of the corresponding proteins were not up regulated. We speculated that this phenomenon was due to the up regulation of the 6-fructokinase and pyruvate kinase proteins, which are key enzymes of glycolysis. We discuss the relationship of metabolism with the regulation of deoxynivalenol production in F. asiaticum. PMID- 30284113 TI - Robotic-assisted laparoscopic apical suspension: description of the spiral technique. AB - This video's objective was to describe our spiral technique and surgical steps of robotic-assisted laparoscopic apical suspension (RALAS) in the treatment of patients with symptomatic apical vaginal prolapse. A 70-year-old Caucasian woman, gravida 3, para 2 had symptomatic pelvic organ prolapse (POP) apical/anterior stage III. At pelvic ultrasound evaluation, the uterus was small and normal appearing of adnexa bilaterally. She failed pessaries and is sexually active. The most relevant complaints were vaginal bulging and pressure. She denied urinary incontinence. During the surgery, we used (1) 3-0, V-LocTM (Covidien) and we reinforced these absorbable sutures with (2) 2-0, GORE-TEX(r) Suture (Gore Medical). The Si da Vinci Surgical System was used with 4 arms and 5 trocars configuration, docked on the patient's left side. On the right/left apical support, we used V-Loc and Gore-Tex and these provided the initial 2 points suspension on the uterosacral ligaments (USL). We like to attach the left to the right USL. We then developed the space between the bladder and vagina and proceed with a plication of the pubocervical fascia with V-loc sutures. Two anterior apical support sutures were taken from the vagina to the transversalis fascia on the anterior abdominal wall and then hid behind the bladder peritoneum. The tension of these sutures was maintained with Hem-o-lock (TeleFlex) and LAPRA-TY (Ethicon). With the spiral technique, we secured these sutures through aponeurosis of abdominal muscle inside-outside-inside using a Carter-Thomason (Cooper Surgical) laparoscopic port closure system. This technique may provide a better long-term support for the anterior apical compartment. PMID- 30284115 TI - A cost of musical training? Sensorimotor flexibility in musical sequence learning. AB - We report an experiment that tested the flexibility of sensorimotor learning in sequence production. Nonpianists and pianists learned simple melodies by ear under one of two auditory feedback conditions: one with normal pitch mapping (higher pitches to the right) and one with an inverted (reversed) mapping. After learning, both groups played melodies from memory while experiencing each feedback condition. Both groups exhibited sensorimotor learning and produced fewer errors at test while hearing the feedback used during training as opposed to the alternate feedback condition. However, learning was unstable for pianists who learned melodies with an inverted feedback condition, who produced more errors at test than pianists who learned melodies with normal-pitch mapping. Acquiring musical skill may therefore constrain subsequent sensorimotor flexibility. PMID- 30284116 TI - A Simon-like effect in Go/No-Go tasks performed in isolation. AB - The present study was conducted to decipher whether a spatial correspondence effect can emerge in Go/No-Go tasks (cSE, in reference to Donders' type c task) performed in isolation (participant alone in the cubicle). To this aim, a single participant was centrally positioned in front of a device and was required to respond by a hand key-press to the color of the stimulus. Half the participants were seated in front of a table equipped with only one response key and the other half in front of a table equipped with two response keys (one active and the other one useless). Using a substantial number of subjects (48) and trials (960), the present study revealed a numerically small but statistically reliable cSE. This result contrasts with referential coding predictions and suggests that the representation of a concurrently active response is not a prerequisite for the cSE to emerge. Moreover, the presence of a second response button in the participant's peripersonal space exerted no measurable influence on the cSE. The lack of statistical power of numerous previous studies may explain why the cSE has often been considered to be nil. PMID- 30284117 TI - Prevalence of Early Childhood Caries in India - A Systematic Review. AB - Early Childhood Caries (ECC) is a serious public health problem in developed as well as developing nations, with high prevalence among children around the world. This systematic review of the national literature was undertaken to document the prevalence of Early Childhood Caries. Studies evaluating the prevalence of Early Childhood Caries (ECC) in the Indian population were investigated. The method under evaluation was the use of a caries experience index to calculate the prevalence of ECC. An extensive literature search was done in the following databases: PubMed, IndMED and Cochrane upto June 2016. A modified version of the Newcastle-Ottawa Scale for cross-sectional studies was used for assessment of the quality of the studies. A systematic literature search yielded 503 publications from the various databases searched. Based on the inclusion and exclusion criteria, the final number of included studies were 54. Among the included studies, 19 studies were carried out in the state of Karnataka. Analysis of all the included studies revealed the overall prevalence of ECC in India to be 49.6%. Andhra Pradesh was found to have the highest prevalence of ECC at 63%, and the lowest prevalence was reported in Sikkim (41.92%). This review has reported a high prevalence of ECC in India. None of the states reported prevalence below 40%. The government should identify ECC as a national priority which requires significant attention. PMID- 30284114 TI - Patient and provider communication about employment following a cancer diagnosis. AB - PURPOSE: Cancer treatment can precipitate functional limitations that restrict survivors' ability to work. Yet, it is unclear whether healthcare providers discuss the potential for employment limitations with their patients. We assessed the frequency of patient-provider communication about employment, from the perspectives of survivors, and examined whether receiving a treatment summary was associated with employment communication. METHODS: Cancer survivors who were working at diagnosis were identified from the Health Information National Trends Survey-4, conducted in 2014 (n = 290). Separate multivariable regression analyses examined the associations between survivor characteristics and employment communication and receipt of a treatment summary and employment communication. RESULTS: Among cancer survivors who were working at diagnosis, 62.69% (95% CI 54.42-70.95) reported discussing employment with any healthcare provider at any time since diagnosis. Younger cancer survivors and those more recently treated were more likely to ever have employment discussions. Survivors who received a treatment summary were also more likely to ever discuss employment with any healthcare provider than survivors who did not receive a treatment summary (OR = 3.47, 95% CI 1.02-11.84). CONCLUSIONS: Approximately two thirds of cancer survivors who were working at diagnosis ever discussed employment with a healthcare provider. Thus, for a sizable portion of cancer survivors, the potential impact of cancer on employment is never discussed with any healthcare provider. IMPLICATIONS FOR CANCER SURVIVORS: Efforts are needed to proactively screen patients for cancer-related work limitations, empower patients to discuss employment concerns with their healthcare providers, and develop interventions that support survivors' goals for working throughout treatment and recovery.

AB - Lutein has various biological activities, its application in food and pharma industries are limited due to poor aqueous solubility, stability, and bioavailability. To achieve various benefits, lutein-poly (lactic-co-glycolic acid) (PLGA)-phospholipid (PL) nanocapsules were prepared. Lutein-PLGA NCs (+PL) were synthesized, characterized and its bioavailability was studied in vitro and in vivo. The cellular uptake and anti-proliferative activity were analyzed in Hep G2 cells. The mean size and zeta value of lutein-PLGA NCs (+PL) were 140 +/- 6 nm and - 44 mV. The amorphous nature of lutein in PLGA NCs (+PL) was confirmed by XRD and DSC. In vitro lutein release kinetics showed an initial burst followed by sustainable release up to 86%. In vitro bioavailability showed 62.7% higher lutein bioaccessibility than lutein in free form. The AUC of lutein after single oral dose of lutein-PLGA NCs (+PL) revealed 3.91-fold (plasma), 2.89-fold (liver), and 3.12-fold (eyes) higher absorption than the control (mixed micelles). The IC50 of lutein-PLGA NCs (+PL) in Hep G2 cells at 72 h was 4.5 MUM as opposed to 23.4 MUM for lutein in free form. Thus, results reveal that PL added to PLGA NCs helps in enhancing the solubility which in turn resulted in its better bioavailability and bioefficacy. PMID- 30284122 TI - Carbohydrate-restricted diet promotes skin senescence in senescence-accelerated prone mice. AB - This study used senescence-accelerated prone mice (SAMP8) to examine the effects of a carbohydrate-restricted diet on aging and skin senescence, to determine how long-term carbohydrate restriction affects the aging process. Three-week-old male SAMP8 mice were divided into three groups after 1 week of preliminary feeding: one was given a controlled diet, the other was given a high-fat diet, and the third was given a carbohydrate-restricted diet. Ad libitum feeding was administered until the mice reached 50 weeks of age. Before the end of the test period, a grading test was used to evaluate visible aging in the mice. After the test period, serum and skin samples in mice were obtained and submitted for analysis. As a result, the grading test demonstrated that there was significant progression of visible aging in the carbohydrate-restricted group, as well as a decreased survival rate. Histological examination of the skin revealed that the epidermis and dermis in the carbohydrate-restricted group had become thinner. Analysis of the mechanisms involved demonstrated an increase in serum interleukin 6, aggravated skin senescence, inhibition of skin autophagy and activation of skin mTOR. Therefore, this study proved that a carbohydrate-restricted diet promoted skin senescence in senescence-accelerated mice. PMID- 30284120 TI - The Role of Deprescribing in Older Adults with Chronic Kidney Disease. AB - Older adults with chronic kidney disease (CKD) often experience polypharmacy, a recognized predictor of prescribing problems including inappropriately dosed medications, drug-drug and drug-disease interactions, morbidity and mortality. Polypharmacy is also associated with nonadherence, which leads to recurrent hospitalizations and poorer hemodialysis outcomes in CKD patients. Further complicating medication management in this vulnerable population are the physiologic changes that occur with both age and CKD. This guide for pharmacists and prescribers offers considerations in medication evaluation and management among older adults with CKD. Careful prescribing with the aid of tools such as the American Geriatrics Society Beers Criteria can support safe medication use and appropriate prescribing. Polypharmacy may be systematically addressed through 'deprescribing,' an evidence-based process that enables identification and elimination of unnecessary or inappropriate medications. Detailed guidance for deprescribing in older adults with CKD has not been published previously. We highlight three specific targets for medication optimization and deprescribing in older adults with CKD: (1) proton pump inhibitors, (2) oral hypoglycemic agents, including newer classes of agents, and (3) statins. These medication classes have been chosen as they represent three of the most commonly prescribed classes of medications in the United States. For each area, we review considerations for medication use in older adults with CKD and provide strategies to avoid, modify, or discontinue these medications when clinically indicated. By utilizing deprescribing techniques, pharmacists are well positioned to help decrease the medication burden in older adults with CKD, thereby potentially reducing the risk of morbidity and mortality associated with polypharmacy. PMID- 30284123 TI - Opioid Activity in the Locus Coeruleus Is Modulated by Chronic Neuropathic Pain. AB - Pain affects both sensory and emotional aversive responses, often provoking depression and anxiety-related conditions when it becomes chronic. As the opioid receptors in the locus coeruleus (LC) have been implicated in pain, stress responses, and opioid drug effects, we explored the modifications to LC opioid neurotransmission in a chronic constriction injury (CCI) model of short- and long term neuropathic pain (7 and 30 days after nerve injury). No significant changes were found after short-term CCI, yet after 30 days, CCI provoked an up-regulation of cAMP (cyclic 5'-adenosine monophosphate), pCREB (phosphorylated cAMP response element binding protein), protein kinase A, tyrosine hydroxylase, and electrical activity in the LC, as well as enhanced c-Fos expression. Acute mu opioid receptor desensitization was more intense in these animals, measured as the decline of the peak current caused by [Met5]-enkephalin and the reduction of forskolin-stimulated cAMP produced in response to DAMGO. Sustained morphine treatment did not markedly modify certain LC parameters in CCI-30d animals, such as [Met5]-enkephalin-induced potassium outward currents or burst activity and c Fos rebound after naloxone precipitation, which may limit the development of some typical opioid drug-related adaptations. However, other phenomena were impaired by long-term CCI, including the reduction in forskolin-stimulated cAMP accumulation by DAMGO after naloxone precipitation in morphine dependent animals. Overall, this study suggests that long-term CCI leads to changes at the LC level that may contribute to the anxiodepressive phenotype that develops in these animals. Furthermore, opioid drugs produce complex adaptations in the LC in this model of chronic neuropathic pain. PMID- 30284124 TI - From Inner Speech to Mind-Wandering: Developing a Comprehensive Model of Inner Mental Activity Trajectories. AB - The objective of this work was to develop a comprehensive model of inner mental activity's trajectories. For this purpose, a review of updated research was conducted on the wandering mind topic - a phenomenon that has been recently conceptualized and that has become a focus of interest in cognitive sciences - alongside early psychological postulates on the inner speech phenomenon that were brought back to the surface of scientific literature. In summary, this article presents a reformulation of the spontaneous thought model by Andrews-Hanna et al. (2017), broadening its scope to approach inner mental activity in all its forms and transitions. It is concluded that modern cognitive research has overlooked the full complexity of different types and forms of consciousness' expressions, understanding them as isolated phenomena and sub-dimensioning their trajectories during the flow of experience. This, mainly, due to a scarce incorporation of temporality and morphology to current theoretical models. It is proposed that cognitive acts described in modern research (spontaneous, controlled, involuntary, etc.) are, in synthesis, different symbolic and expressive natures of inner mental activity or thought phenomenon, which current literature has failed to understand as a whole. This article constitutes a contribution to future theoretical and experimental research that seeks out to explore the nature of thought and its development during a cognitive act.

AB - OBJECTIVE: To assess vaccine coverage for a cohort of children who have been in the care of the child welfare system compared to children in the general population. METHODS: This retrospective cohort study used population-based administrative health data for a 2008 birth cohort of children from Alberta, Canada. We assessed coverage at ages 2 (n = 44,206) and 7 (n = 42,241) for three vaccines with different administration schedules for children in care (at any period before the age of assessment) and those who had never been in care, comparing them using risk differences and relative risks (RRs). We similarly assessed coverage for children not in care who shared characteristics of children in care. RESULTS: At age two, vaccination coverage for children in care ranged from 54.3% to 81.4%, depending on vaccine. In comparison, coverage for those not in care ranged from 74.2% to 87.4%. At age seven, coverage for children in care ranged from 53.1% to 65.3%, compared to 76.6% to 83.4% for those not in care. For all vaccines at both ages, the risk for being under-vaccinated was higher for children in care (e.g., diphtheria, pertussis, tetanus, polio, Haemophilus influenzae type b at age 7: RR 2.01, 95% confidence interval [CI] (1.74-2.32). Even for children not in care who had characteristics similar to children in care, we found children in care had lower coverage. CONCLUSION: Children in care have consistently lower vaccine coverage than children not in care. Policies and practices should promote optimal access to vaccination for these children.

AB - The present study examined the relationship between clinical findings and mutation analyses in children with Familial Mediterranean Fever (FMF) in the inner Black Sea region of Turkey. This retrospective, cross-sectional study included patients with FMF who were evaluated between 2007 and 2015. FMF was diagnosed according to the Tel Hashomer criteria. FMF mutations were analyzed using a Real-time PCR System (Roche Diagnostics, Mannheim, Germany), and patients were classified into three groups according to allele status. The most common symptom was abdominal pain (99%, n = 197). The most frequent mutations were M694V and R202Q. Chest pain was reported more often in patients homozygous for M694V (61.4%). Although fever, abdominal pain, and arthritis were more commonly observed with the M694V mutation, chest pain was the most common symptom in R202Q carriers (n = 10, 32.3%). Proteinuria was observed in 42 (21.2%) patients, frequently accompanied by the M694V mutation (28.6%). The most common mutations in children with FMF in Turkey were M694V and R202Q. Recurrent abdominal pain and arthritis/arthralgia were commonly observed in patients with M694V and R202Q mutations. Moreover, chest pain was commonly seen with the R202Q mutation. Thus, R202Q might be a disease-causing mutation in FMF patients. PMID- 30284127 TI - Association Between SSR Molecular Markers and Chemical and Sensory Traits of Cacao Samples Using Multiple Regression Analysis. AB - The sensory properties of cacao beans are linked to the chemical composition of the seeds, and both characteristics are the partial results of its allelic composition. Therefore, it is useful to search for molecular markers associated with these traits. We perform multiple regression analysis to associate previously generated data of alleles generated with 12 SSR (of cultivated cacao trees) with data obtained from chemical and sensory characterization (of beans) of plants grown in the southern region from Mexico. When the association was significant, the mathematical models for predictive purposes were proposed. All phenotypic traits evaluated showed equations with setting values R2 > 0.5. All chemical characters tested have a significant association with at least two alleles (P < 0.05). In addition, the fat content was associated with six molecular markers (mTcCIR03209, mTcCIR12188, mTcCIR19286, mTcCIR07150, mTcCIR19310). The most common allele was mTcCIR12188, which was associated with the contents of eicosanoic acid, moisture, fat and total polyphenols content. The mTcCIR28362 allele is associated with sensory characters bitterness, musty odor, and roasted odor. These alleles could be useful as molecular markers of chemical and sensory characteristics of cacao samples.

PMID- 30284131 TI - Survival Impact of Total Resected Lymph Nodes in Esophageal Cancer Patients With and Without Neoadjuvant Chemoradiation. AB - BACKGROUND: Current esophageal treatment guidelines suggest that, when more than 15 lymph nodes are detected, dissection should be done as the minimum requirement for staging in esophageal squamous cell carcinoma (ESCC) patients undergoing esophagectomy without induction chemoradiotherapy (CRT). However, for neoadjuvant CRT, there is limited information. We sought to clarify the role of lymphadenectomy in ESCC patients with and without neoadjuvant CRT. PATIENTS AND METHODS: Data on 3156 ESCC patients receiving esophagectomy with (group 1, n = 1399) and without (group 2, n = 1757) neoadjuvant CRT between 2008 and 2014 were collected from a national cancer registry in Taiwan. The impact of the resected lymph nodes on overall survival was assessed according to pathologic stages. A Cox regression model was used to identify prognostic factors for overall survival. RESULTS: Five-year overall survival rates were 35.6% for the entire group, 30.32% for group 1, and 39.55% for group 2 (p < 0.0001 for group 1 vs group 2). The best cutoff value was 21 lymph nodes in both group 1 and group 2. In group 1, the independent prognostic factors included age >= 54 years, clinical N status, y-pathologic T, y-pathologic N, y-pathologic stage, grade, location, margin status, esophagectomy (thoracoscopic vs open), and number of total resected lymph nodes (<= 21 vs > 21). For group 2, the independent prognostic factors were gender, clinical stage, pathologic T, pathologic N, tumor length, grade, and margin status. CONCLUSIONS: Extent of lymphadenectomy was associated with survival in patients with neoadjuvant CRT followed by esophagectomy. The optimum lymphadenectomy should be modulated by pathologic stage. PMID- 30284132 TI - The Role of Completion Lymph Node Dissection for Sentinel Lymph Node-Positive Melanoma. AB - PURPOSE AND METHODS: Completion lymph node dissection (CLND) for sentinel lymph node (SLN)-positive melanoma patients has been guideline-concordant standard of care since adoption of lymphatic mapping and SLN biopsy for the management of clinically node-negative melanoma patients more than 20 years ago. However, a trend for omission of CLND has been observed over the past decade, and we now have randomized, controlled clinical trial data to help guide treatment recommendations. Publication of these data prompted an American Society of Clinical Oncology-Society of Surgical Oncology 2018 clinical practice guideline update for these patients. RESULTS AND CONCLUSIONS: Systematic review of current evidence supports a selective, individualized approach to CLND for SLN-positive melanoma. For low-risk, low-volume micrometastatic disease, SLN biopsy may be both diagnostic and therapeutic, and close clinical follow-up with imaging or CLND are reasonable options for appropriately selected patients. For higher-risk patients, omission of CLND requires careful consideration of risks versus benefits, relevant histopathology, and individualized patient discussion. This should address patient comorbidities and life expectancy, the predicted likelihood of additional positive nodes, availability of imaging surveillance, likelihood of adherence to imaging and clinical follow-up, consequences of regional recurrence, and the prognostic value of complete nodal staging and its impact on adjuvant therapy recommendations or clinical trial participation. Data on long-term outcomes, cost, and patient-reported quality of life measures are not yet available. PMID- 30284133 TI - Delayed Bleeding After Colorectal Endoscopic Submucosal Dissection: When Is Emergency Colonoscopy Needed? AB - BACKGROUND: Endoscopic submucosal dissection (ESD) is an effective treatment for early-colorectal cancer. Although delayed bleeding is a serious potential complication, there is no consensus on the optimal protocol to determine which cases require emergency colonoscopy. AIMS: This study aimed to assess the risk factors for delayed bleeding after ESD and evaluate the "watch and wait" strategy for delayed bleeding. The "watch and wait" strategy was used for delayed bleeding, unless the shock index was >= 1 and/or a moderate amount of hematochezia occurred more than five occurrences. METHODS: This study included 404 patients who had undergone endoscopic resection for 439 lesions between April 2012 and February 2018. Patients were classified into the bleeding group or the no-bleeding group to investigate the risk factors for delayed bleeding, and to assess the necessity of emergency colonoscopy. RESULTS: Twenty-seven patients into the bleeding group and 412 into the no-bleeding group were classified. However, no case required emergency colonoscopy for hemostasis under "watch and wait strategy." Multivariate analysis revealed the risk factors for bleeding were rectal lesion (OR 5.547, 95% CI 1.456-21.130; P = 0.012) and lesion size >= 40 mm (OR 3.967, 95% CI 1.003-15.696; P = 0.05). CONCLUSIONS: Risk factors for delayed bleeding are rectal lesions and lesion size >= 40 mm. This watch and wait strategy resulted in no requirements for emergency colonoscopy or blood transfusion, and no serious conditions caused by delayed bleeding. PMID- 30284134 TI - Pharmacological Treatment of Opioid-Induced Constipation Is Effective but Choice of Endpoints Affects the Therapeutic Gain. AB - BACKGROUND: Widespread opioid use has led to increase in opioid-related adverse effects like constipation. We examined the impact of study endpoints on reported treatment benefits. METHODS: Using MEDLINE, EMBASE, and ClinicalTrials.gov, we searched for randomized control trials targeting chronic opioid-induced constipation (OIC) and subjected them to meta-analysis. Data are given with 95% confidence intervals. RESULTS: Thirty trials met our inclusion criteria. Combining all dichotomous definitions of responders, active drugs were consistently more effective than placebo, with an odds ratio (OR): 2.30 [2.01 2.63; 15 studies], independent of the underlying drug mechanism. The choice of endpoints significantly affected the therapeutic gain. When time from drug administration to defecation was used, the OR decreased from 4.74 [2.71-4.74] at 6 h or less to 2.46 [1.80-3.30] at 24 h (P < 0.05). Using other response definitions, the relative benefit over placebo was 2.10 [1.77-2.50; 12 studies] for weekly bowel frequency, 2.03 [1.39-2.95; 9 studies] for symptom scores, 2.21 [1.25-3.90; 4 studies] for global assessment scales, and 1.27 [0.79-2.03; 7 studies] for rescue laxative use. CONCLUSION: While treatment of OIC with active drugs is more effective than placebo, the relative gain depends on the choice of endpoints. The commonly used time-dependent response definition is associated with the highest response rate but is of questionable relevance in a chronic disorder. The limited data do not clearly demonstrate a unique advantage of the peripherally restricted opioid antagonists, suggesting that treatment with often cheaper agents should be optimized before shifting to these novel expensive agents. PMID- 30284135 TI - Resveratrol Improves Recovery and Survival of Diet-Induced Obese Mice Undergoing Extended Major (80%) Hepatectomy. AB - INTRODUCTION: Loss of hepatic epidermal growth factor receptor (EGFR) expression is a cause for the increased perioperative risk for complications and death in patients with obesity and fatty liver undergoing liver resection. Herein, we set out to identify agents that might increase EGFR expression and improve recovery for patients with fatty liver undergoing resection. Using the diet-induced obese (DIO) mouse model of fatty liver, we examined resveratrol as a therapy to induce EGFR expression and improve outcomes following 80% partial hepatectomy (PH) in a murine model. METHODS: DIO mice were fed resveratrol or carrier control by gavage. EGFR expression and the response to major (80%) PH were examined. RESULTS: Based on an Illumina analysis, resveratrol was identified as increasing EGFR gene expression in A549 cells. Resveratrol was observed to also increase EGFR protein expression in A549 cells. DIO mice fed resveratrol by gavage (75 mg/kg) demonstrated an increased EGFR expression without the identified hepatic toxicity. Resveratrol and control mice subjected to 80% PH, a model of high mortality hepatectomy in DIO mice, demonstrated macroscopically decreased fatty liver and fewer liver hemorrhagic petechiae. Resveratrol pretreatment ameliorated liver injury and accelerated regeneration of the hepatic remnant after 80% PH including decreasing serum ALT and bilirubin, while increasing hepatic PCNA expression. Resveratrol increased induction of p-STAT3 and p-AKT after 80% hepatectomy. Resveratrol pretreatment significantly improved survival rates in DIO mice undergoing extended 80% PH. CONCLUSIONS: Oral resveratrol restores EGFR expression in fatty liver. Resveratrol may be a promising protective agent in instances where extensive hepatic resection of fatty liver is required.

AB - Acute pancreatitis is a human disease with multiple causes that leads to autodigestion of the pancreas. There is sufficient evidence to support the key role of sustained increase in cytosolic calcium concentrations in the early pathogenesis of the disease. To clarify the mechanism of maintaining calcium homeostasis in the cell and pathological processes caused by calcium overload would help to research directly targeted therapeutic agents. We will specifically review the following: intracellular calcium homeostasis and regulation, the occurrence of calcium overload in acinar cells, the role of calcium overload in the pathogenesis of AP, the treatment strategy proposed for calcium overload.

AB - Although the experience of time is of central relevance for psychopathology, qualitative approaches to study the inner experience of time have been largely neglected in autism research. We present results from qualitative data acquired from 26 adults with high functioning autism spectrum disorder (ASD). Employing inductive content analysis we identified a distinct pattern of interrupted time experience in ASD. Individuals with ASD seemed to implement structured and routine behavior by future planning to guarantee that the present passed uninterrupted. We reason that the success of corresponding compensatory mechanisms determines the development of distress and noticeable symptoms. Considering recent theories on Bayesian perceptual inference we relate the syndrome of interrupted time experience to the putative neuronal mechanisms underlying time experience. PMID- 30284138 TI - Correlation of FFR-derived from CT and stress perfusion CMR with invasive FFR in intermediate-grade coronary artery stenosis. AB - Only one-third of intermediate-grade coronary artery stenosis (i.e. 40-70% diameter narrowing) causes myocardial ischemia, requiring most often additional invasive work-up with invasive fractional flow reserve (FFR). To evaluate the correlations between FFR estimates derived from computed tomography (FFRCT) and adenosine perfusion cardiac magnetic resonance (CMR) with invasive FFR in intermediate-grade stenosis. Thirty-seven patients (mean age 61 +/- 9 years; 25 men) who underwent adenosine perfusion CMR, quantitative coronary angiography and FFR in the work-up for intermediate-grade stenoses (n = 39) diagnosed at coronary CT angiography were retrospectively evaluated. Blinded FFRCT analysis was computed on each intermediate-grade lesion and correlated to the FFR values. On adenosine CMR, subendocardial time-enhancement maximal upslopes, normalized by respective left ventricle cavity upslopes, were obtained distal to a coronary stenosis (RISK area) and in remote myocardium (REMOTE area). The perfusion was subsequently assessed without (uncorrected RISK) and after correction for remote perfusion (relative myocardial perfusion index = REMOTE/RISK ratio), and then correlated to the FFR values. Differences in correlations were tested with z statistics and considered statistically significant different at a p < 0.05 level. The average FFR value was 0.85 +/- 0.10 (0.60-0.98 range), 28% (n = 11) was <= 0.80. FFR value correlated poorly with uncorrected RISK upslopes (r = 0.151; p = 0.36), but equally strongly with FFRCT (r = 0.675; p < 0.001) and the relative myocardial perfusion index (r = - 0.63) (p < 0.001; z = 6.72) for assessment of lesion-specific ischemia. Both FFRCT and adenosine perfusion CMR strongly correlate with invasive FFR measurements for intermediate-grade stenosis. These preliminary findings pave the way for further studies evaluating non-invasively intermediate coronary stenosis in clinical practice. PMID- 30284139 TI - Predictors of Quality of Life in Montreal, Canada: A Longitudinal Study. AB - This study sought to assess factors associated with quality of life (QoL), and predictive of improvements in QoL over time, in a population-based cohort study. A 4-year longitudinal survey was administered to 2433 individuals at the study baseline; of these, 1828 individuals participated in Wave 2, and 1303 participated in Wave 3. QoL was measured by the Satisfaction with Life Domains Scale. Thirty-two variables were correlated with baseline QoL and together explained 58.2% of the variance. Eleven variables were independent predictors of improvement in QoL over time. Among these variables, social support and stress/coping showed the strongest association with QoL, and neighbourhood characteristics had an additional influence. Multidimensional modelling of a broad spectrum of the factors related to QoL enabled situating mental health and well-being in an ecological system with attendant implications for public health and social policy intervention to facilitate improvement of QoL in the population. PMID- 30284140 TI - Natural products from anaerobes. AB - Natural product discovery in the microbial world has historically been biased toward aerobes. Recent in silico analysis demonstrates that genomes of anaerobes encode unexpected biosynthetic potential for natural products, however, chemical data on natural products from the anaerobic world are extremely limited. Here, we review the current body of work on natural products isolated from strictly anaerobic microbes, including recent genome mining efforts to discover polyketides and non-ribosomal peptides from anaerobes. These known natural products of anaerobes have demonstrated interesting molecular scaffolds, biosynthetic logic, and/or biological activities, making anaerobes a promising reservoir for future natural product discovery. PMID- 30284141 TI - Post-exposure distribution of selenium and aluminum ions and their effects on superoxide dismutase activity in mouse brain. AB - The study was conducted to determine how aluminum (Al) and selenium (Se) ions alone and in combination affect superoxide dismutase (SOD) activity and to evaluate the distribution of these elements in the blood and the brain of laboratory mice. SOD activity in mouse brain was evaluated after single-time (within 24 h) and repeated (over 14 days) intraperitoneal (IP) injections of SeO32-, Al3+, and (SeO32-+Al3+) solutions. The control mice received IP injections of the same volume of saline. Aluminum concentration in mouse blood increased both after single-time and repeated injections of AlCl3 and the combined (AlCl3 + Na2SeO3) solutions. The concentration of Se increased in blood after single-time and repeated injections of Na2SeO3 and the combined (AlCl3 + Na2SeO3) solutions. After the single-time injection of the experimental solutions, the concentrations of both Al and Se in mouse brain remained at baseline, but after repeated injections of (AlCl3 + Na2SeO3) solutions increased aluminum concentration. A single IP injection of Al did not change SOD activity in mouse brain, while a single injection of Se or the Se + Al mixture decreased it. After 14 days, IP injections of Al or Se alone did not affect SOD activity, while their combination decreased it. Our results showed that Se ions decreased SOD activity in mouse brain after both single-time and repeated IP injections of selenium-containing solutions. The study failed to show a direct or linear effect of increased Al or Se concentrations on SOD activity in mouse brain. PMID- 30284142 TI - In silico 'fishing' using known small regulatory RNA (sRNA) candidates as the decoy from Escherichia coli, Salmonella typhi and Salmonella typhimurium manifested 14 novel sRNA candidates in the orthologous region of Proteus mirabilis. AB - Proteus mirabilis, a gram-negative bacterium of the family Enterobacteriaceae, is a leading cause of urinary tract infection (UTI) with rapid development of multi drug resistance. Identification of small regulatory RNAs (sRNAs), which belongs to a class of RNAs that do not translate into a protein, could permit the comprehension of the regulatory roles this molecules play in mediating pathogenesis and multi-drug resistance of the organism. In this study, comparative sRNA analysis across three different members of Enterobacteriaceae (Escherichia coli, Salmonella typhi and Salmonella typhimurium) was carried out to identify the sRNA homologs in P. mirabilis. A total of 232 sRNA genes that were reported in E. coli, S. typhi and S. typhimurium were subjected to comparative analysis against P. mirabilis HI4320 genome. We report the detection of 14 sRNA candidates, conserved in the orthologous regions of P. mirabilis, that are not included in Rfam database. Northern-blot analysis was carried out for selected three sRNA candidates from the current investigation and three known sRNA from Rfam of P. mirabilis. The expression pattern of the six sRNA candidates shows that they are growth stage-dependant. To the best of our knowledge, this is the first report on the identification of sRNA candidates in P. mirabilis. PMID- 30284144 TI - Mosaicism diminishes the value of pre-implantation embryo biopsies for detecting CRISPR/Cas9 induced mutations in sheep. AB - The production of knock-out (KO) livestock models is both expensive and time consuming due to their long gestational interval and low number of offspring. One alternative to increase efficiency is performing a genetic screening to select pre-implantation embryos that have incorporated the desired mutation. Here we report the use of sheep embryo biopsies for detecting CRISPR/Cas9-induced mutations targeting the gene PDX1 prior to embryo transfer. PDX1 is a critical gene for pancreas development and the target gene required for the creation of pancreatogenesis-disabled sheep. We evaluated the viability of biopsied embryos in vitro and in vivo, and we determined the mutation efficiency using PCR combined with gel electrophoresis and digital droplet PCR (ddPCR). Next, we determined the presence of mosaicism in ~ 50% of the recovered fetuses employing a clonal sequencing methodology. While the use of biopsies did not compromise embryo viability, the presence of mosaicism diminished the diagnostic value of the technique. If mosaicism could be overcome, pre-implantation embryo biopsies for mutation screening represents a powerful approach that will streamline the creation of KO animals. PMID- 30284143 TI - AGXT2 and DDAH-1 genetic variants are highly correlated with serum ADMA and SDMA levels and with incidence of coronary artery disease in Egyptians. AB - Dimethylarginine aminodehydrolase (DDAH1) and alanine glyoxylate aminotransferase2 (AGXT2) are two enzymes that contribute in asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) metabolism. Hence they affect production and bioavailability of eNOS-derived nitric oxide (NO) and consequently healthy blood vessels. The major aims of the current study were to investigate the association of genetic variants of AGXT2 rs37369, AGXT2 rs16899974 and DDAH1 rs997251 SNPs with incidence of coronary artery disease (CAD) in Egyptians and to correlate these variants with the serum levels of ADMA and SDMA. The study included 150 subjects; 100 CAD patients and 50 healthy controls. Genotyping was performed by qPCR while the ADMA and SDMA concentrations were assayed by ELISA. Both serum ADMA and SDMA concentrations were significantly higher in CAD patients compared to controls (both p < 0.0001). Genotype distributions for all studied SNPs were significantly different between CAD patients and controls. Carriers of AGXT2 rs37369-T allele (CT + TT genotypes) and AGXT2 rs16899974-A allele (CA + AA genotypes) had 2.4- and 2.08-fold higher risk of having CAD than CC genotype in both SNPs (p = 0.0050 and 0.0192, respectively). DDAH1 rs997251 TC + CC genotypes were associated with 2.3-fold higher risk of CAD than TT genotype (p = 0.0063). Moreover, the AGXT2 rs37369 TT and AGXT2 rs16899974 AA genotypes were associated with the highest serum ADMA and SDMA while DDAH1 rs997251 CC genotype was associated with the highest ADMA. AGXT2 rs37369-T, AGXT2 rs16899974-A, and DDAH1 rs997251-C alleles represent independent risk factors for CAD in the Egyptians.

AB - The rapid advancement of CRISPR technology has enabled targeted epigenome editing and transcriptional modulation in the native chromatin context. However, only a few studies have reported the successful editing of the epigenome in adult animals in contrast to the rapidly growing number of in vivo genome editing over the past few years. In this review, we discuss the challenges facing in vivo epigenome editing and new strategies to overcome the huddles. The biggest challenge has been the difficulty in packaging dCas9 fusion proteins required for manipulation of epigenome into the adeno-associated virus (AAV) delivery vehicle. We review the strategies to address the AAV packaging issue, including small dCas9 orthologues, truncated dCas9 mutants, a split-dCas9 system, and potent truncated effector domains. We discuss the dCas9 conjugation strategies to recruit endogenous chromatin modifiers and remodelers to specific genomic loci, and recently developed methods to recruit multiple copies of the dCas9 fusion protein, or to simultaneous express multiple gRNAs for robust epigenome editing or synergistic transcriptional modulation. The use of Cre-inducible dCas9 expressing mice or a genetic cross between dCas9- and sgRNA-expressing flies has also helped overcome the transgene delivery issue. We provide perspective on how a combination use of these strategies can facilitate in vivo epigenome editing and transcriptional modulation. PMID- 30284150 TI - Did we see it Coming? An Evaluation of the Swedish Early Awareness and Alert System. AB - BACKGROUND: Early awareness and alert systems have been established in many countries but evidence on their ability to accurately prioritize new medicines (for early assessment) is limited. OBJECTIVE: The purpose of this study was to assess whether the Swedish Early Awareness and Alert System identified and prioritized (i.e., produced early assessment reports for) new medicines that would go on to have substantial economic impact. METHODS: We adapted a study design commonly used in the assessment of diagnostic test accuracy. The prioritization made by the Swedish Early Awareness and Alert System prior to marketing authorization comprised the index test and the national drug sales data in the second year post-authorization served as the reference standard. All initial marketing authorization applications for medicinal products processed by the European Medicines Agency between 2010 and 2015 (study population) were classified using the index test and the reference standard. RESULTS: Two hundred and fifty-three new medicinal products processed by the European Medicines Agency comprised the study population. Of these, 71 were prioritized by the Swedish Early Awareness and Alert System and 21 were classified as having substantial economic impact. The sensitivity and positive predictive value were 76.2% and 22.5%, respectively. Subgroup analyses showed that the accuracy of prioritization, in terms of sensitivity, was 100% for antineoplastic/immunomodulating agents. CONCLUSIONS: The Swedish Early Awareness and Alert System identified all new medicines that would go on to have substantial economic impact and prioritized most of these medicines. Our findings provide reassurance to decision makers who rely on the outputs of the Swedish Early Awareness and Alert System to keep informed about new medicines. Moreover, this study also provides valuable insights to stakeholders willing to establish or evaluate their own early awareness and alert activities and systems. PMID- 30284149 TI - Inhibition of the ubiquitination of HSF1 by FBXW7 protects the intestine against ischemia-reperfusion injury. AB - Epithelial apoptosis is an important factor in intestinal ischemia-reperfusion (I/R) injury. Heat shock factor 1 (HSF1) is a classical stress response factor that directly regulates the transcription of heat shock proteins (HSPs) under stress conditions. Although HSPs are involved in protecting the intestine against I/R, the mechanism whereby HSF1 is regulated in I/R is poorly understood. Here, we show that the ubiquitin ligase FBXW7 targets HSF1 for ubiquitination and degradation in intestinal I/R. In this study, we found that FBXW7 expression was upregulated at the transcriptional level in intestinal mucosae subjected to I/R. In Caco-2 and IEC-6 cells subjected to hypoxia/reoxygenation (H/R), a high FBXW7 level led to excessive HSF1 ubiquitination and degradation. FBXW7 knockdown attenuated HSF1 ubiquitination and downregulation and accelerated HSPB1 and HSP70 expression. In addition, FBXW7 deletion alleviated the apoptosis of intestinal epithelial cells, as evidenced by decreased activation of caspase-3 and caspase 9. The results suggest that FBXW7 suppression protects against intestinal I/R, at least partly through the HSF1/HSP pathway. These findings indicate that FBXW7 may be a potential therapeutic target for inhibiting intestinal mucosa apoptosis during intestinal I/R.

AB - The invasion of new regions by exotic pests has been more than ever a critical issue that warrants coordinated international actions to manage established populations and prevent further spreading. Invasive insects can undermine the ecological equilibrium of both natural and agricultural ecosystems. Moreover, increasing temperatures due to climatic change exacerbate this problem by allowing pests to further reach regions previously considered unsuitable. The tomato pinworm Tuta absoluta (Meyrick) (Lepidoptera) is an exotic pest native to Peru that has spread beyond Neotropical America. In Europe, its occurrence was reported in Spain in 2006, and thereafter, it has spread throughout the Mediterranean Basin and further into Africa and part of Asia. While T. absoluta can cause losses to tomato production all over the globe, the differences in each invaded region (e.g., climate, vegetation) may affect its population dynamics and, consequently, management protocols. Therefore, the main intent of this forum paper is to explore how European growers and researchers are dealing with T. absoluta in the Mediterranean area. As for many other invasive pests, the best approach has been the adoption of integrated pest management (IPM). Specifically, the integration of biological control agents (e.g., mirid predators and egg parasitoids), microbial insecticides (i.e., Bacillus thuringiensis), selective chemical insecticides, and sex pheromone-based control has proven adequate, especially in tomato greenhouses. Nonetheless, some of the challenges ahead include the development of resistant tomato cultivars, the management of wild vegetation and companion plants to optimize the conservation of natural enemies and their effectiveness at the crop level, the management of insecticide resistance, and the improvement of sex pheromone-based tactics.

AB - The search for new antibacterial products, the mechanisms of action of which differ from conventional antibiotics is a current a topical issue. The objective of our research is to identify the presence of silver in meat and organs of broiler chicks that had been given colloidal silver. The results show that the broiler chick meat contains silver in quantities safe for humans regardless of the use of colloidal silver. Comparison of meat analysis results in experimental and control groups indicate that the ratio of parameters distribution variance for all birds to the mean variance by group for each measured no statistical differences in the chemical composition of bird's meat of experimental and control groups. The analysis also confirmed the existing difference in chemical composition of leg muscle meat and chest muscle meat (P < 0.05), whereas leg muscle contains more fat (6.81% vs. 2.85%) and less protein (20.25% vs. 22.81%). PMID- 30284153 TI - Detecting drug-resistant tuberculosis in chest radiographs. AB - PURPOSE: Tuberculosis is a major global health threat claiming millions of lives each year. While the total number of tuberculosis cases has been decreasing over the last years, the rise of drug-resistant tuberculosis has reduced the chance of controlling the disease. The purpose is to implement a timely diagnosis of drug resistant tuberculosis, which is essential to administering adequate treatment regimens and stopping the further transmission of drug-resistant tuberculosis. METHODS: A main tool for diagnosing tuberculosis is the conventional chest X-ray. We are investigating the possibility of discriminating automatically between drug resistant and drug-sensitive tuberculosis in chest X-rays by means of image analysis and machine learning methods. RESULTS: For discriminating between drug sensitive and drug-resistant tuberculosis, we achieve an area under the receiver operating characteristic curve (AUC) of up to 66%, using an artificial neural network in combination with a set of shape and texture features. We did not observe any significant difference in the results when including follow-up X-rays for each patient. CONCLUSION: Our results suggest that a chest X-ray contains information about the likelihood of a drug-resistant tuberculosis infection, which can be exploited computationally. We therefore suggest to repeat the experiments of our pilot study on a larger set of chest X-rays. PMID- 30284154 TI - Treatment of Disfiguring Cutaneous Lesions in Neurofibromatosis-1 with Everolimus: A Phase II, Open-Label, Single-Arm Trial. AB - BACKGROUND: Cutaneous neurofibromas cause disfigurement and discomfort in individuals with neurofibromatosis type 1 (NF-1). METHODS: The primary objective of this phase II, open-label, single-arm trial was to assess whether orally administered everolimus reduced the surface volume of cutaneous neurofibromas in patients with NF-1. RESULTS: Of 22 patients who took the study drug, 17 completed the trial; 5 patients withdrew due to adverse events. Sixteen patients had photographs of sufficient quality for assessment of the primary outcome. A significant reduction in lesion surface volume, defined as an end of trial volume > 2 standard errors (SE) less than baseline volume, was observed for 4/31 lesions (13%) from 3/16 patients (19%). Additionally, a statistically significant absolute change in average height for paired lesions was observed (p = 0.048). Although not a prespecified outcome measure, a dramatic reduction in the size of 3 large plexiform neurofibromas with a cutaneous component was also noted and documented by measurement of maximum circumference or magnetic resonance imaging based volumetric analysis. Adverse events were common in this trial, but no serious adverse events occurred. CONCLUSIONS: Although this was a small, exploratory trial that was not powered for significance, the reduction in surface volume observed in this study is noteworthy assuming that the natural course for untreated lesions is to maintain or increase in volume. Future studies are needed with larger study populations that incorporate longer durations of treatment and better standardization of volumetric measurements.

PMID- 30284155 TI - Histogram Analysis Parameters Derived from Conventional T1- and T2-Weighted Images Can Predict Different Histopathological Features Including Expression of Ki67, EGFR, VEGF, HIF-1alpha, and p53 and Cell Count in Head and Neck Squamous Cell Carcinoma. AB - PURPOSE: To analyze associations between histogram analysis parameters derived from conventional magnetic resonance imaging (MRI) and different histopathological features in head and neck squamous cell carcinoma (HNSCC). PROCEDURES: Thirty-four patients with histologically proven primary HNSCC were prospectively acquired. Histogram analysis was derived from pre-contrast T1 weighted (T1w) and T2-weighted (T2w) images. In all cases, expression of HIF 1alpha, VEGF, EGFR, p53, Ki67, and p16 as well as tumor cell count was analyzed. RESULTS: In the overall sample, inverse correlation between entropy derived from T1w images and p53 expression (p = - 0.458, P = 0.01) was found. Furthermore, p10 derived from T1w images correlated with VEGF expression (p = 0.371, P = 0.04). In the p16-positive tumors, VEGF expression correlated with several parameters derived from T1w images: mean (p = 0.481, P = 0.032), p10 (p = 0.489, P = 0.029), p25 (p = 0.475, P = 0.034), median (p = 0.468, P = 0.037), and mode (p = 0.492, P = 0.028). Several T2w parameters were associated with p53 expression: mean (p = 0.569, P = 0.007), p25 (p = 0.508, P = 0.019), p75 (p = 0.479, P = 0.028), median (p = 0.555, P = 0.009), and mode (p = 0.468, P = 0.033). Kurtosis derived from T2w images correlated with cell count (p = 0.534, P = 0.013). In p16-negative carcinomas, T2w parameters correlated with p53 expression: max (p = 0.736, P = 0.015), p90 (p = 0.687, P = 0.028), and standard deviation (p = 0.760, P = 0.011). T2w p10 (p = - 0.709, P = 0.022) and T2w p25 (p = - 0.733, P = 0.016) correlated also with HIF-1alpha expression. CONCLUSIONS: Multiple associations between histogram parameters derived from T1w and T2w images and clinically relevant histopathological features were found in HNSCC. Therefore, imaging parameters can be also used as surrogate markers for tumor cellularity, proliferation, and vascularization in HNSCC. The identified correlations differed significantly between p16-positive and p16-negative cancers. PMID- 30284156 TI - Reduction in Cannabis Use and Functional Status in Physical Health, Mental Health, and Cognition. AB - Treatment for substance use disorders has traditionally been abstinence-oriented, but evaluating the merits of low-level cannabis use as potential treatment endpoint may identify benefits that are clinically relevant for treatment-seeking individuals who do not attain abstinence. This study explores if reduction in cannabis use to a lower level of use is related to improved physical health, mental health, and perceived cognitive functions. Study participants with a history of problematic cannabis use (n = 111) completed assessments. Regression models were used to explore the relationship between past 30-day cannabis use levels (abstinent [57%], low use [22%] defined as less than or equal to 3 days per week, and heavy use [22%] defined as 4 or more days of use per week) and functional status in physical health, mental health, and cognition. Compared to heavy users, both abstinent and low-use individuals were similarly associated with better global health, appetite, and depression outcomes. Abstinent users also reported improved sleep, anxiety, and self-reported cognitive functioning relative to heavy users. Thus, reduction in cannabis use to lower levels is associated with beneficial outcomes important to health and other areas of functioning in individuals with problematic cannabis use. PMID- 30284158 TI - Prevention Research with Indigenous Communities to Expedite Dissemination and Implementation Efforts. AB - Effectively translating evidence-based interventions into clinic and community settings is an increasing priority for health researchers. The successful dissemination and implementation (D&I) of interventions found efficacious ensures that major health funders such as the National Institutes of Health can demonstrate a return on investment in biomedical and behavioral research and that all populations receive maximum benefit from scientific discoveries. However, the products of research efficacy trials, the evidence-based interventions, are rarely designed with D&I in mind, rendering these interventions fundamentally misaligned with real-world settings. Further, while some evidence-based interventions have been successfully adapted for implementation in indigenous communities, few such examples have been published. Literature regarding the adoption and implementation of evidence-based interventions in indigenous communities is scarce, and the feasibility of scaling up successful interventions is poorly understood, potentially widening health disparities. The Intervention Research to Improve Native American Health (IRINAH) partners are generating efficacy data on community-responsive and engaged interventions that are also designed to facilitate D&I efforts, reducing the time between research to practice to benefit indigenous communities, should these interventions prove effective. In this manuscript, we provide an overview and key challenges of D&I science with indigenous communities. We then use IRINAH case studies to highlight strategies that IRINAH partners are using to plan for the scale-up and implementation of the studies. We conclude with recommendations to inform the next phase of IRINAH research efforts. PMID- 30284159 TI - Using Zoning as a Public Health Tool to Reduce Oversaturation of Alcohol Outlets: an Examination of the Effects of the New "300 Foot Rule" on Packaged Goods Stores in a Mid-Atlantic City. AB - The oversaturation of alcohol outlets can have disastrous public health consequences. The goal of this study was to evaluate the potential impact of new zoning legislation, TransForm Baltimore on locations of alcohol outlets. More specifically, the study sought to determine the effect of the new zoning code on the potential redistribution of alcohol outlets and also provide empirical support for the need to actively monitor redistribution of outlets to avoid further inequitable oversaturation in disadvantaged neighborhoods. Data on off premise alcohol outlets (e.g., packaged goods stores) were obtained from the Board of Liquor License Commissioners for Baltimore City. The alcohol outlets were geocoded and assigned to zoning parcels. Churches and schools were also geocoded. The alcohol outlets were also assigned to census tracts to calculate socioeconomic statuses. One hundred seventy-two of the 263 off-premise packaged goods stores (PGS) were in violation of the new zoning law. TransForm will reduce the land parcels available to alcohol outlets by 27.2%. Areas containing non conforming PGS were more likely to have a higher percentage of Black residents, single parent-families, unemployment, household poverty, and vacancy compared to Baltimore City averages and areas without non-conforming PGS. Planning enforcement efforts need to accompany related laws to prevent/reduce overconcentration of PGS in disadvantaged neighborhoods. PMID- 30284161 TI - Co-contamination of antibiotics and metals in peri-urban agricultural soils and source identification. AB - To identify the dominant sources of contamination in peri-urban land, this study investigated the concentrations and distributions of antibiotics and metals in agricultural soil of this area. An index of landscape development intensity (LDI) was used to characterize the distribution of human disturbance-related land use. The results showed that total antibiotic concentration in the soil reached 395.55 MUg/kg and that chlortetracycline was the predominant antibiotic compound, with a relatively high mean concentration of 30.62 MUg/kg. In soils, the mean concentrations of Cu, Zn, and Pb were 38.41, 127.88, and 56.61 mg/kg and those of Al, Fe, and K were 83.73, 24.17, and 23.42 g/kg, respectively. A redundancy analysis showed that the landscape pattern in a 300-m buffer zone can well explain the variation in the concentrations of antibiotics and metals (24%, p < 0.05). The LDI in the 300-m buffer zone significantly correlated with the concentrations of total antibiotics and total amounts of Cu and Zn in the soil, suggesting that the risk of soil contamination increases with the intensity of anthropogenic activities. A structural equation modeling analysis indicated that Al, Cu, and Zn could significantly aggravate accumulation of tetracycline antibiotics in the soil, whereas there were only significantly direct paths from Cu to ciprofloxacin and norfloxacin. Overall, the results showed that aggravated co-contamination of antibiotics and metals occurs in agricultural soil under intensive human disturbance. PMID- 30284162 TI - Occurrence and risk assessment of heavy metals in water, sediment, and fish from Dongting Lake, China. AB - In this study, 15 representative surface waters and sediments and seven typical fish were collected during the wet season in 2016 to explore the occurrence, chemical fractionation, and ecological risk of heavy metals (Cu, Zn, Pb, Cd, Cr, Hg, As, and Ni) in aquatic ecosystems of Dongting Lake in China. In surface water, the concentrations of all elements were lower than the third grade of the surface water quality standards (GB3838-2002). The highest concentrations of Zn, Pb, Cd, Ni, and Cu were found in the outlet of Dongting Lake, whereas As and Cr were highest in the Xiangjiang River Delta area. In surface sediments, the concentration decreased in the order of Zn > Cr > Pb > Cu > Ni > As>Cd > Hg; the highest concentration of all elements, except for Hg, was located in the Xiangjiang River Delta area; for chemical fractionation, Cr, Hg, Zn, As, Ni, and Cu were mainly residual fractionation; and Pb and Cd were mainly in a reducible state and fraction soluble in acid, respectively. In fish muscle, the concentrations of all elements were lower than relevant standards; the highest concentration appeared in fish living in the middle-lower and demersal layers. As for the feeding habits of fish, the average concentration decreased in the order of carnivorous > omnivorous > herbivorous fish. The potential ecological risk and the ratio of secondary phase to primary phase assessment showed that Cd and Hg had the highest ecological risk and that Cd and Pb had a high risk of secondary release. A health risk assessment showed that drinking water and fish for consumption in urban and rural areas around Dongting Lake were in the acceptable level. PMID- 30284160 TI - Phytohormones enhanced drought tolerance in plants: a coping strategy. AB - Drought stress is a severe environmental constraint among the emerging problems. Plants are highly vulnerable to drought stress and a severe decrease in yield was recorded in the last few decades. So, it is highly desirable to understand the mechanism of drought tolerance in plants and consequently enhance the tolerance against drought stress. Phytohormones are known to play vital roles in regulating various phenomenons in plants to acclimatize to varying drought environment. Abscisic acid (ABA) is considered the main hormone which intensifies drought tolerance in plants through various morpho-physiological and molecular processes including stomata regulation, root development, and initiation of ABA-dependent pathway. In addition, jasmonic acid (JA), salicylic acid (SA) ethylene (ET), auxins (IAA), gibberellins (GAs), cytokinins (CKs), and brassinosteroids (BRs) are also very important phytohormones to congregate the challenges of drought stress. However, these hormones are usually cross talk with each other to increase the survival of plants in drought conditions. On the other hand, the transgenic approach is currently the most accepted technique to engineer the genes responsible for the synthesis of phytohormones in drought stress response. Our present review highlights the regulatory circuits of phytohormones in drought tolerance mechanism. PMID- 30284163 TI - Biochar amendment immobilizes arsenic in farmland and reduces its bioavailability. AB - This study aimed to determine effects of biochar derived from wheat straw at 500 degrees C on arsenic immobilization in a soil-Brassica campestris L system. When the soils amended with 4% modified biochar (MBC), 0.5% Fe grit as zero-valent iron (ZVI), 0.5% Fe grit + 4% MBC (ZMBC), 0.5% ZVI + 4% biochar (ZBC), 4% biochar (BC), and control (without amendments), it confirmed that available arsenic concentration in soils occurred in the following order: ZMBC < MBC < ZVI < ZBC < Control < BC. Water-soluble As (WSAs) was reduced by 89.74% and 92.30% in MBC- and ZMBC-amended soils, respectively, compared to the control. When MBC applied into soil, As uptake of shoot and root decreased by 44.55% and 45.40%, respectively, and ZMBC resulted in 74.92% and 71.80% reduction in shoot and root As of Brassica campestris L. Immobilization effect of As in ZBC was also observed though BC elevated plant As uptake significantly. The immobilization effect of MBC was mainly attributed to Fe2O3 impregnation illustrated by x-ray diffraction (XRD) and scanning electron microscopy (SEM) images through sorption, precipitation, and coprecipitation. Such Fe containing complexes might impede As translocation from root to shoot and subsequently reduce As accumulation in the plant with modified biochar amendment. PMID- 30284164 TI - Antimicrobial and antifouling properties of versatile PPSU/carboxylated GO nanocomposite membrane against Gram-positive and Gram-negative bacteria and protein. AB - Biofouling is a serious issue in membrane-based water and wastewater treatment as it critically compromises the efficacy of the water treatment processes. This investigation demonstrates the antimicrobial and antifouling properties of a nanocomposite membrane system composed of carboxyl-functionalized graphene oxide (COOH-GO) and polyphenylsulfone (PPSU). The PPSU/COOH-GO nanocomposite membrane exhibited excellent antimicrobial properties, achieving maximum bacteriostasis rates of 74.2% and 81.1% against the representative Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa, respectively) and 41.9% against the representative Gram-positive bacterium (Staphylococcus aureus). The PPSU/COOH-GO nanocomposite membrane inhibited the attachment, colonization, and the biofilm formation of three species. Antifouling was assessed through filtration experiments using a model foulant bovine serum albumin (BSA). The fouling mechanisms were investigated by Hermia's models (complete blocking, intermediate blocking, standard blocking, and cake formation), and the analysis involved fitting the volumetric flux decline experimental data to models. The fouling study revealed a less irreversible fouling and increased flux recovery ratio for the PPSU/COOH-GO nanocomposite membrane. Complete blocking of pores and cake formation were the major fouling mechanisms for the membrane. PMID- 30284165 TI - Effective industrial regeneration of arsenic poisoning waste selective catalytic reduction catalyst: contaminants removal and activity recovery. AB - In this work, an environmental friendly industrial regeneration approach has been proposed to remove the surface poisoning and recover the catalytic activity of waste V2O5-WO3/TiO2 catalyst. Alkaline treatment and acid wash are combined for the waste catalyst regeneration process, which is applied for the arsenic and alkali metal removal, respectively. The crystal structure was well maintained as anatase phase and the surface area was increased during the regeneration, which is favorable for the following active component addition step and regenerated process. The XPS results illustrated that the surface contaminants (arsenic and sodium) were removed and V(IV) was loaded on the regenerated catalyst. Based on the deNOx evaluations, the catalytic activity of the regenerated sample is increased to the level of commercial fresh catalyst. The present industrial regeneration process provides a promising method for the comprehensive recovery of waste catalyst and further understanding in the field of secondary resource recycle. PMID- 30284166 TI - Enhanced photocatalytic activity of BiVO4 powders synthesized in presence of EDTA for the decolorization of rhodamine B from aqueous solution. AB - Bismuth vanadate (BiVO4) powders were successfully synthesized in presence of EDTA via microwave irradiation and used as photocatalysts in the oxidation reaction of rhodamine B (rhB) under visible light. Different concentrations of EDTA (0.5 to 10%) to chelate Bi3+ ions were employed on the BiVO4 synthesis. Under the presence of EDTA, a monoclinic crystalline structure was obtained, whereas a mixture of monoclinic and tetragonal phases was observed in the absence of EDTA. In addition, the use of different EDTA concentrations promoted the formation the different shapes of particles. The BiVO4 sample synthesized with low concentration of EDTA (0.5%) exhibited about 85% of rhB decolorization in 300 min at pH 7.5. Therefore, this high efficiency can be attributed to a combination of intrinsic properties such as the morphology type and monoclinic structure of BiVO4 particles. PMID- 30284167 TI - Minimal-flow ECCO2R in patients needing CRRT does not facilitate lung-protective ventilation. AB - Extracorporeal CO2 removal (ECCO2R) is intended to facilitate lung protective ventilation in patients with hypercarbia. The combination of continuous renal replacement therapy (CRRT) and minimal-flow ECCO2R offers a promising concept for patients in need of both. We hypothecated that this system is able to remove enough CO2 to facilitate lung protective ventilation in mechanically ventilated patients. In 11 ventilated patients with acute renal failure who received either pre- or postdilution CRRT, minimal-flow ECCO2R was added to the circuit. During 6 h of combined therapy, CO2 removal and its effect on facilitation of lung protective mechanical ventilation were assessed. Ventilatory settings were kept in assisted or pressure-controlled mode allowing spontaneous breathing. With minimal-flow ECCO2R significant decreases in minute ventilation, tidal volume and paCO2 were found after one and three but not after 6 h of therapy. Nevertheless, no significant reduction in applied force was found at any time during combined therapy. CO2 removal was 20.73 ml CO2/min and comparable between pre- and postdilution CRRT. Minimal-flow ECCO2R in combination with CRRT is sufficient to reduce surrogates for lung-protective mechanical ventilation but was not sufficient to significantly reduce force applied to the lung. Causative might be the absolute amount of CO2 removal of only about 10% of resting CO2 production in an adult as we found. The benefit of applying minimal flow ECCO2R in an uncontrolled setting of mechanical ventilation might be limited. PMID- 30284168 TI - Rolipram plus Sivelestat inhibits bone marrow-derived leukocytic lung recruitment after cardiopulmonary bypass in a primate model. AB - Cardiopulmonary bypass (CPB) recovery is complicated by lung inflammation from bone marrow (BM)-derived polymorphonuclear leukocytes (PMNs) and monocytes (MO). Although Sivelestat reduces inflammatory mediators and Rolipram inhibits PMN and MO activation, any kinetic effects to improve CPB recovery in vivo are unknown. We hypothesized that intraoperative co-administration of these compounds would reduce CPB-induced lung inflammation through downregulation of PMN and MO recruitment. A 2-h CPB was surgically established in cynomolgus monkeys (n = 13), and BM leukocyte release and lung recruitment were monitored postoperatively by flow cytometry with 5'-bromo-2'-deoxyuridine (BrdU) and cytokine ELISA. Either Sivelestat, Sivelestat plus Rolipram, or saline (control) was administered intraoperatively and both peripheral and perfusion sampling courses revealed BrdU labeled cells representative of activated leukocyte infiltration. Levels of cytokines CD11b and CD18 were leukocytic activation markers. Sivelestat plus Rolipram attenuated increases in CPB-associated circulating band cells, prolonged BM-transit time (PMN: 121.0 +/- 3.7 to 96.2 +/- 4.3 h [control], p = 0.012; MO: 84.4 +/- 4.1 to 61.4 +/- 3.0 h [control], p = 0.003), and reduced their alveolar appearance. CD11b-mediated PMN and MO changes during CPB and the post-surgical increases of Interleukin (IL)-6 and IL-8 in the bronchoalveolar lavage fluid were suppressed. Sivelestat alone increased PMN transit time to 115.8 +/- 6.6 h, but monocytes were unaffected. Therefore, Rolipram has additive inhibitory effects with Sivelestat on the CPB-induced activation and release of BM-derived PMNs and MO and their recruitment to the lungs. Co-administration of these compounds could, therefore, hold value for preventing CPB-induced lung injury. PMID- 30284169 TI - Chronically Happy.

AB - BACKGROUND: Late-stage colorectal cancer (CRC) is associated with significantly less effective treatment and poorer survival than early-stage colorectal cancer. OBJECTIVE: Identify and assess patient characteristics, demographic factors, and lifestyle factors that are associated with late-stage colorectal cancer at diagnosis. APPROACH: We linked two longstanding statewide, population-based registry databases: the New Hampshire Colonoscopy Registry and the New Hampshire State Cancer Registry, to assess the associations between patient characteristics and late-stage CRC diagnoses. The State Cancer Registry provided information on cancer stage and the Colonoscopy Registry provided detailed information on patient characteristics and lifestyle factors, allowing these factors to be analyzed in relation to colorectal cancer stage. KEY RESULTS: The risk of late stage CRC diagnosis was highest among those diagnosed at a young age (< 50 years old) (OR 1.81, 95% CI 1.27-2.58). Those with Medicaid were also at increased risk, particularly < 65 years of age (OR 2.32, 95% CI 1.05-5.26). A family or personal history of polyps and/or CRC was associated with early stage at diagnosis (p = 0.014). CONCLUSIONS: Public health outreach and screening efforts should focused on patients at risk of late-stage CRC to encourage earlier diagnosis and prevention. Underserved patients have a lower rate of CRC screening and an increased risk of late-stage CRC, emphasizing the critical need to reach these populations. Further investigation of susceptibility characteristics and the effectiveness of non-invasive early screening techniques is warranted to address the late-stage CRC diagnoses in young individuals. PMID- 30284172 TI - Quality Improvement and Personalization for Statins: the QUIPS Quality Improvement Randomized Trial of Veterans' Primary Care Statin Use. AB - BACKGROUND: Implementation of new practice guidelines for statin use was very poor. OBJECTIVE: To test a multi-component quality improvement intervention to encourage use of new guidelines for statin use. DESIGN: Cluster-randomized, usual care controlled trial. PARTICIPANTS: The study population was primary care visits for patients who were recommended statins by the 2013 guidelines, but were not receiving them. We excluded patients who were over 75 years old, or had an ICD9 or ICD10 code for end-stage renal disease, muscle pain, pregnancy, or in vitro fertilization in the 2 years prior to the study visit. INTERVENTIONS: A novel quality improvement intervention consisting of a personalized decision support tool, an educational program, a performance measure, and an audit and feedback system. Randomization was at the level of the primary care team. MAIN MEASURES: Our primary outcome was prescription of a medium- or high-strength statin. We studied how receiving the intervention changed care during the quality improvement intervention compared to before it and if that change continued after the intervention. KEY RESULTS: Among 3787 visits to 43 primary care providers, being in the intervention arm tripled the odds of patients being prescribed an appropriate statin (OR 3.0, 95% CI 1.8-4.9), though the effect resolved after the personalized decision support ended (OR 1.7, 95% CI 0.99-2.77). CONCLUSIONS: A simple, personalized quality improvement intervention is promising for enabling the adoption of new guidelines. CLINICALTRIALS. GOV IDENTIFIER: NCT02820870. PMID- 30284174 TI - Preferences for Physician Roles in Follow-up Care During Survivorship: Do Patients, Primary Care Providers, and Oncologists Agree? PMID- 30284173 TI - Telehealth Interventions Designed for Women: an Evidence Map. AB - BACKGROUND: Telehealth employs technology to connect patients to the right healthcare resources at the right time. Women are high utilizers of healthcare with gender-specific health issues that may benefit from the convenience and personalization of telehealth. Thus, we produced an evidence map describing the quantity, distribution, and characteristics of evidence assessing the effectiveness of telehealth services designed for women. METHODS: We searched MEDLINE(r) (via PubMed(r)) and Embase(r) from inception through March 20, 2018. We screened systematic reviews (SRs), randomized trials, and quasi-experimental studies using predetermined eligibility criteria. Articles meeting inclusion criteria were identified for data abstraction. To assess emerging trends, we also conducted a targeted search of ClinicalTrials.gov . RESULTS: Two hundred thirty four primary studies and three SRs were eligible for abstraction. We grouped studies into focused areas of research: maternal health (n = 96), prevention (n = 46), disease management (n = 63), family planning (n = 9), high-risk breast cancer assessment (n = 10), intimate partner violence (n = 7), and mental health (n = 3). Most interventions focused on phone as the primary telehealth modality and featured healthcare team-to-patient communication and were limited in duration (e.g., < 12 weeks). Few interventions were conducted with older women (>= 60 years) or in racially/ethnically diverse populations. There are few SRs in this area and limited evidence regarding newer telehealth modalities such as mobile-based applications or short message service/texting. Targeted search of clinical.trials.gov yielded 73 ongoing studies that show a shift in the use of non-telephone modalities. DISCUSSION: Our systematic evidence map highlights gaps in the existing literature, such as a lack of studies in key women's health areas (intimate partner violence, mental health), and a dearth of relevant SRs. With few existing SRs in this literature, there is an opportunity for examining effects, efficiency, and acceptability across studies to inform efforts at implementing telehealth for women. PMID- 30284175 TI - Oxidative stress does not contribute to the release of proinflammatory cytokines through activating the Nod-like receptor protein 3 inflammasome in patients with obstructive sleep apnoea. AB - PURPOSE: The study was conducted to test the hypothesis that oxidative stress leads to the release of proinflammatory cytokines by activating the Nod-like receptor protein (NLRP)3 inflammasome in patients with obstructive sleep apnoea (OSA). METHODS: The study recruited 247 participants who were divided into cases and healthy control groups. OSA patients were subdivided into four subgroups according to sex, blood pressure, body mass index (BMI), and severity of disease. No significant differences were found between cases and controls with respect to age or sex. Peripheral blood samples were collected for analysis after examination, and the serum concentrations of oxidative stress (8-isoprostane), inflammation (interleukin (IL)-18, IL-1beta, IL-6, tumour necrosis factor (TNF) alpha), and NLRP3 inflammasome components (NLRP3, caspase-1, and ASC) were detected by enzyme-linked immunosorbent assay. RESULTS: The serum concentrations of both oxidative stress and proinflammatory factors were higher in OSA patients than healthy controls. Subgroup analysis also revealed significant differences according to the apnoea-hypopnea index and BMI. Additionally, correlations were identified between 8-isoprostane and proinflammatory factors (IL-1beta, IL-18, and TNF-alpha). Multiple regression analysis suggested that sleep parameters and BMI affected inflammation. However, no differences were observed in the serum level of NLRP3 inflammasome components between patients and controls. Furthermore, stratified analysis revealed no additional differences. CONCLUSIONS: The current study suggests that oxidative stress leads to inflammation by mechanisms other than activation of the NLRP3 inflammasome in OSA patients. Furthermore, both sleep apnoea and BMI influenced the serum concentration of inflammatory mediators. PMID- 30284176 TI - Multiplex testing for Factor II and Factor V mutations in thrombophilia: technical verification and clinical validation of the cobas(r) Factor II and Factor V test. AB - Laboratory testing for thrombophilia is complicated but essential for diagnosis. In 2017, the cobas(r) Factor II and Factor V Test (cobas F2F5 test) was launched for use with the cobas z 480 analyzer. This qualitative polymerase chain reaction test enables multiplex Factor II and Factor V testing with flexible reporting and workflow efficiency. Here, we report the results from studies investigating the performance of the cobas F2F5 test. Technical performance verification, clinical validation, external laboratory performance, and workflow comparison studies were performed. Fresh and frozen whole-blood and genomic DNA (gDNA) samples were tested, and several manual and automated DNA isolation methods were used. Bidirectional Sanger sequencing was used to verify genotypes identified by the cobas F2F5 test. One hundred percent agreement between the cobas F2F5 test and Sanger sequencing was observed for all genotypes. An external laboratory using remnant clinical samples also yielded 100% agreement between cobas F2F5 test results and their routine testing method. The cobas F2F5 test reduced the total sample processing time compared with the LightCycler(r) 1.2 platform (98.6 vs 420.2 min; 96 samples). Hemoglobin, extraction buffer, and ethanol contamination of the gDNA sample can lead to invalid results. The cobas F2F5 test has a high degree of accuracy for identification of Factor II and Factor V genotypes. This multiplex testing with short sample processing time can reduce handling errors and increase efficiency. Both manual and automated DNA isolation methods can be used with the cobas F2F5 test. PMID- 30284178 TI - Clinical Pharmacokinetics of Second-Generation Triazoles for the Treatment of Invasive Aspergillosis and Candidiasis. AB - Second-generation triazoles were developed in response to the quest for more efficacious and safer therapeutic options for the treatment of severe systemic aspergillosis and candidiasis. These agents include voriconazole, posaconazole, isavuconazole, and ravuconazole. The aim of this review was to present and compare the pharmacokinetic characteristics of second-generation triazoles for the treatment of invasive aspergillosis and candidiasis, emphasizing their clinical implications. The MEDLINE, Scopus, EBSCO, Google Scholar, and SCIndeks databases were searched using advanced search options, including the names of second-generation triazoles and pharmacokinetic terms as keywords. The intravenous administration of voriconazole, posaconazole, and isavuconazole results in stable pharmacokinetics of these drugs, with mostly predictable variations influenced by common and usually known factors in routine clinical settings. The high oral bioavailability of isavuconazole and, to some extent, voriconazole makes them suitable for intravenous-to-oral switch strategies. Except for intravenous voriconazole (due to the accumulation of the toxic vehicle hydroxypropyl betadex), dose reduction of second-generation triazoles is not needed in patients with renal failure; patients with hepatic insufficiency require dose reduction only in advanced disease stages. The introduction of therapeutic drug monitoring could aid attempts to optimize the blood concentrations of triazoles and other drugs that are known to or that possibly interact, thus increasing treatment efficacy and safety. There is a need for new studies that are designed to provide useful data on second-generation triazole pharmacokinetics, particularly in special circumstances such as central nervous system and ocular infections, infections in newborns and infants, and in subjects with genetic polymorphisms of metabolizing enzymes. PMID- 30284177 TI - Sugar-Sweetened Beverages and Child Health: Implications for Policy. AB - PURPOSE OF REVIEW: Various policies to reduce sugar-sweetened beverages (SSBs) consumption in children have been implemented. Here, we review the evidence on whether these policies are effective in reducing SSB intake and whether a reduction in SSB intake results in a concomitant reduction in child obesity. We also highlight ethical concerns with such efforts. RECENT FINDINGS: The evidence supporting relationship between SSB consumption and child body mass index (BMI) is consistently small and lacks causality. The effects of policies are unclear; taxation has no clear relationship to SSB purchasing, innovative marketing outlets make it difficult to examine the effects of restricting marketing on SSB consumption, and there is no evidence that reducing SSB availability in schools decreases consumption. Research studies with rigorous and reproducible study designs are needed to examine whether reducing SSB consumption reduces child obesity, and to identify implementable policies that not only reduce SSB consumption but also child weight. PMID- 30284179 TI - The association between treatment appropriateness according to EUCAST and CLSI breakpoints and mortality among patients with candidemia: a retrospective observational study. AB - To evaluate the association between appropriate antifungal treatment and mortality among patients with candidemia using different breakpoint definitions. In a retrospective study, we included all adults with candidemia in a tertiary center between 2009 and 2015. We defined three versions of appropriate (covering) antifungal treatment, according to Clinical and Laboratory Standards Institute (CLSI) 2008, CLSI 2012, and European Committee on Antimicrobial Susceptibility Testing (EUCAST) (2017 update) breakpoints. For empiric treatment, we evaluated the association with 30-day mortality. For definitive treatment, we evaluated the association with 90-day mortality among patients surviving the first week after candidemia onset. Adjusted odds ratios (OR) from a bivariate logistic regression with 95% confidence intervals are reported. We identified 302 patients with 308 separate candidemia episodes. The crude 30-day mortality was 55% (168/308). Resistance to anidulafungin increased from 3.5 to 51.6% and to fluconazole from 15.2 to 44.1%, when applying CLSI 2008 and EUCAST definitions, respectively. Appropriate empirical treatment was significantly associated with lower 30-day mortality using the CLSI 2008 definitions, adjusted OR 0.56 (0.33-0.96). The associations were similar, though not statistically significant for EUCAST, 0.58 (0.33-1.00), and CLSI 2012, OR 0.62 (0.37-1.04). Appropriate definitive treatment according to CLSI 2012 and EUCAST was independently associated with lower 90-day mortality, ORs 0.31 (0.13-0.75) and 0.44 (0.23-0.8), respectively. With CLSI 2008, the association was similar but not statistically significant, OR 0.4 (0.11 1.41), with few isolates classified as resistant. Considering the major shift in resistance prevalence when applying CLSI 2008, CLSI 2012, and EUCAST breakpoint definitions, no major differences were observed in their association with mortality. PMID- 30284181 TI - Normative values for the distress thermometer (DT) and the emotion thermometers (ET), derived from a German general population sample. AB - PURPOSE: The distress thermometer (DT) and the emotion thermometers (ET) are short screening instruments for use in oncological practice. The aim of this study was to provide normative values and to analyze the correlational structure of the ET. METHODS: A representative sample of the adult German general population (N = 2437) completed the ET, the PHQ-4, the FACIT-fatigue scale, and the demoralization scale. RESULTS: The percentages of people above the cutoff (>= 4) and the mean scores of the five ET scales were as follows: distress: 39.0%, M = 3.15 +/- 2.62, anxiety: 12.3%, M = 1.36 +/- 1.93, depression: 16.1%, M = 1.65 +/- 2.11, anger: 24.5%, M = 2.33 +/- 2.16, and need for help: 10.7%, M = 1.18 +/- 1.90. Women reported significantly higher levels of burden than men, with effect sizes between 0.07 (anger) and 0.36 (anxiety). All ET dimensions were interrelated (r between 0.44 and 0.69) and significantly correlated with the other scales (r between 0.36 and 0.68). CONCLUSIONS: The normative scores can help qualify assessments of groups of patients. The new four dimensions of the ET provide relevant additional information that is not already covered by the DT. PMID- 30284180 TI - The Importance of CYP19A1 in Estrogen Receptor-Positive Cholangiocarcinoma. AB - CYP19A1, also called aromatase, is a key enzyme for converting androgens to estrogens of estrogen synthesis. Elevated serum estrogen and high expression levels of estrogen-related proteins are found in cholangiocarcinoma (CCA; bile duct cancer). However, the expression of CYP19A1 in relation to estrogen-related proteins, including estrogen receptors (ERalpha, ERbeta, and GPR30) and an estrogen response protein (TFF1), has never been explored in CCA. In this study, we investigated the expressions of CYP19A1 and estrogen-related proteins in CCA tissues (n = 74; 51 males and 23 females) using immunohistochemistry. The results showed that CYP19A1 was overexpressed in CCA cells compared with that in normal bile duct cells in the adjacent tissues. High expression of CYP19A1 was correlated with the metastatic status of the patients. High CYP19A1 expression was also positively correlated with GPR30 expression. Correlation between high CYP19A1 expression in the tumor tissues and shorter survival time was more prominent in male than in female CCA patients. To elucidate further, the effect of CYP19A1 knockdown on a CCA cell line was examined using a specific siRNA. When CYP19A1 gene expression was suppressed, migration and proliferation activities of CCA cells were significantly reduced. Moreover, the cell proliferation of high CYP19A1-expressing KKU-213 cells was more profoundly suppressed by CYP19A1 inhibitors (exemestane and letrozole) than low CYP19A1-expressing KKU-100 cells. Thus, CYP19A1 promotes CCA progression with aggressive clinical outcomes via increased migration and proliferation activities of cancer cells. CYP19A1 can be a potential chemotherapeutic target for CCA, especially in male patients. PMID- 30284182 TI - Test-retest reliability and validity of a single-item Self-reported Family Happiness Scale in Hong Kong Chinese: findings from Hong Kong Jockey Club FAMILY Project. AB - PURPOSE: Family happiness is one major theme of family well-being in Chinese culture. We investigated the reliability and validity of the single-item Self reported Family Happiness Scale (SFHS-1) with the score of 0-10, based on two studies in Hong Kong Chinese. METHODS: Study 1 was a territory-wide population based telephone survey (n = 4038) conducted in 2016. Study 2 was a community based family intervention program conducted during 2012-2013 (n = 1261) to enhance family communication and well-being. Test-retest reliability of the SFHS 1 was assessed over 1 month in Study 2. Family APGAR (Adaption, Partnership, Growth, Affection, Resolve) Scale, Family Communication Scale, Subjective Happiness Scale, 12-item Short Form Health Survey Version 2, and 2-item Patient Health Questionnaire were used to assess the convergent and discriminant validities of the SFHS-1 in both studies. Multiple regression analysis was used to assess the incremental validity by identifying the additional contribution of the SFHS-1 score in predicting subjective happiness. RESULTS: The 1-month test retest reliability assessed by intraclass correlation was 0.76. Family happiness was moderately to strongly correlated with family function, family communication, subjective happiness, mental health-related quality of life and depression, but weakly correlated with physical health-related quality of life. Furthermore, the score of the SFHS-1 added predictive power to mental health-related quality of life and depression in assessing subjective happiness. CONCLUSIONS: Our results have shown the SFHS-1 as a reliable and valid measurement of family happiness in Hong Kong Chinese, suggesting SFHS-1 is highly practicable for future large epidemiological and community-based intervention studies. PMID- 30284183 TI - A systematic review of randomised controlled trials evaluating the use of patient reported outcome measures (PROMs). AB - BACKGROUND: Patient-reported outcome measures (PROMs) could play an important role in identifying patients' needs and goals in clinical encounters, improving communication and decision-making with clinicians, while making care more patient centred. Comprehensive evidence that PROMS are an effective intervention is lacking in single randomised controlled trials (RCTs). METHODS: A systematic search was performed using controlled vocabulary related to the terms: clinical care setting and patient-reported outcome. English language studies were included if they were a RCT with a PROM as an intervention in a patient population. Included studies were analysed and their methodologic quality was appraised using the Cochrane Risk of Bias tool. The protocol was registered with PROSPERO (CRD42016034182). RESULTS: Of 4302 articles initially identified, 115 underwent full-text review resulting in 22 studies reporting on 25 comparisons. The majority of included studies were conducted in USA (11), among cancer patients (11), with adult participants only (20). Statistically significant and robust improvements were reported in the pre-specified outcomes of the process of care (2) and health care (3). Additionally, five, eight and three statistically significant but possibly non-robust findings were reported in the process of care, health and patient satisfaction outcomes, respectively. CONCLUSIONS: Overall, studies that compared PROM to standard care either reported a positive effect or were not powered to find pre-specified differences. There is justification for the use of a PROM as part of standard care, but further adequately powered studies on their use in different contexts are necessary for a more comprehensive evidence base.

PMID- 30284185 TI - 1H, 13C and 15N NMR assignments of self-incompatibility protein homologue 15 from Arabidopsis thaliana. AB - The SPH proteins are a large family of small, disulphide-bonded, secreted proteins, originally found to be involved in the self-incompatibility response in the field poppy (Papaver rhoeas). They are now known to be widely distributed in plants, many containing multiple members of this protein family. Apart from the PrsS proteins in Papaver the function of these proteins is unknown but they are thought to be involved in plant development and cell signalling. There has been no structural study of SPH proteins to date. Using the Origami strain of E. coli, we cloned and expressed one member of this family, SPH15 from Arabidopsis thaliana, as a folded thioredoxin-fusion protein, purified it from the cytosol, and cleaved it to obtain the secreted protein. We here report the assignment of the NMR spectra of SPH15, which contains 112 residues plus three N-terminal amino acids from the vector. The secondary structure propensity from TALOS+ shows that it contains eight beta strands and connecting loops. This is largely in agreement with predictions from the amino acid sequence, which show an additional C terminal strand. PMID- 30284186 TI - Uncertainty Quantification for Non-invasive Assessment of Pressure Drop Across a Coarctation of the Aorta Using CFD. AB - PURPOSE: Numerical assessment of the pressure drop across an aortic coarctation using CFD is a promising approach to replace invasive catheter-based measurements. The aim of this study was to investigate and quantify the uncertainty of numerical calculation of the pressure drop introduced during two essential steps of medical image processing: segmentation of the patient-specific geometry and measurement of patient-specific flow rates from 4D-flow-MRI. METHODS: Based on the baseline segmentation, geometries with different stenosis diameters were generated for a sample of ten patients. The pressure drop generated by these geometries was calculated for different volume flow rates using computational fluid dynamics. Based on these simulations, a second order polynomial fit was calculated. Based on these polynomial fits an uncertainty of pressure drop calculation was quantified. RESULTS: The calculated pressure drop values varied strongly between the patients. In four patients, pressure drops above and below the clinical threshold of 20 mmHg were found. The median standard deviation of the pressure drop was 2.3 mmHg. The sensitivity of the pressure drop toward changes in the volume flow rate or the stenosis geometry varied between patients. CONCLUSION: The uncertainty of numerical pressure drop calculation introduced by uncertainties during image segmentation and measurement of volume flow rates was comparable to the uncertainty of pressure drop measurements using invasive catheterization. However, in some patients this uncertainty would have led to different treatment decision. Therefore, patient-specific uncertainty assessment might help to better understand the reliability of a numerically calculated biomarker as the pressure drop across an aortic coarctation. PMID- 30284187 TI - An integrative review of factors that influence reproductive decisions in women with sickle cell disease. AB - Sickle cell disease is one of the most prevalent genetic diseases in the world. Improvements in care have enabled those affected to experience an improved quality of life, with many affected persons now reaching reproductive age. However, pregnancy poses significant risks for women with the disease and this may affect their reproductive decisions. We conducted an integrative review of the published relevant scientific evidence to ascertain the factors that may influence these women with their reproductive decisions. The electronic databases MEDLINE, CINAHL, and PsychInfo and relevant journals were searched for peer reviewed papers published between 2005 and 2015. Of the 440 papers identified, six papers satisfied the inclusion criteria and were assessed for quality. Results were analysed and synthesised using a thematic approach to produce a narrative report of the findings. Two main themes were identified: (1) factors influencing reproductive decision-making and (2) experiences during pregnancy. Education regarding disease knowledge and genetic implications may improve participation into screening programmes, facilitate the effective treatment needed to create trust in healthcare services, and promote better self management. Educating professionals involved in family planning will facilitate women with this condition to make informed decisions regarding pregnancy. However, further research is required to explore the understanding of the risks involved with sickle cell disease, the best methods to educate people with sickle cell disease, and the influence that partners and families may have on women's reproductive decisions. PMID- 30284188 TI - Methyl Jasmonate Changes the Composition and Distribution Rather than the Concentration of Defence Compounds: a Study on Pyrrolizidine Alkaloids. AB - In this study we investigated the effect of methyl jasmonate (MeJA) application on pyrrolizidine alkaloid (PA) concentration and composition of two closely related Jacobaea species. In addition, we examined whether MeJA application affected herbivory of the polyphagous leaf feeding herbivore Spodoptera exigua. A range of concentrations of MeJA was added to the medium of Jacobaea vulgaris and J. aquatica tissue culture plants grown under axenic conditions. PA concentrations were measured in roots and shoots using LC-MS/MS. In neither species MeJA application did affect the total PA concentration at the whole plant level. In J. vulgaris the total PA concentration decreased in roots but increased in shoots. In J. aquatica a similar non-significant trend was observed. In both Jacobaea species MeJA application induced a strong shift from senecionine- to erucifoline-like PAs, while the jacobine- and otosenine-like PAs remained largely unaffected. The results show that MeJA application does not necessarily elicits de novo synthesis, but rather leads to PA conversion combined with reallocation of certain PAs from roots to shoots. S. exigua preferred feeding on control leaves of J. aquatica over MeJA treated leaves, while for J. vulgaris both the control and MeJA treated leaves were hardly eaten. This suggests that the MeJA induced increase of erucifoline-like PAs can play a role in resistance of J. aquatica to S. exigua. In J. vulgaris resistance to S. exigua may already be high due to the presence of jacobine-like PAs or other resistance factors. PMID- 30284189 TI - Forward and backward recall of serial actions: Exploring the temporal dynamics of working memory for instruction. AB - The ability to flexibly retrieve and implement sequences of actions is essential to motor learning and planning. Recent research has indicated that serial memory for instructions is influenced by presentation modality (spoken vs. visual demonstration) and recall modality (verbal vs. enacted recall). The present study extended this work by investigating the impact of recall direction (forward vs. backward), in addition to that of presentation and recall modality, on working memory for instruction sequences in healthy young adults. Experiment 1 (N = 24) showed that adults were more accurate in backward than forward verbal recall following spoken instructions. In contrast, enacted recall was not influenced by recall direction. Experiment 2 (N = 24) used visual demonstration of instruction sequences and found similar performance levels in forward and backward recall. Experiment 3 (N = 24) replicated the findings from Experiment 1 and 2, along with the previous observation of an advantage for demonstrated over spoken presentation. In addition, the beneficial effects of enacted recall and visual demonstration also emerged in an analysis of response times, specifically in reduced preparation and recall duration. Demonstrated instructions improved maintenance of all items while backward recall enhanced memory of later items in the sequence. These findings provide new insights into the cognitive processes and temporal dynamics of working memory for serial actions and instructions. PMID- 30284191 TI - Molecular modeling investigation of the potential mechanism for phytochemical induced skin collagen biosynthesis by inhibition of the protein phosphatase 1 holoenzyme. AB - The most prominent feature of UV-induced photoaged skin is decreased type 1 procollagen. Increase of the TGF-beta/Smad signaling through inhibition of the TbetaRI dephosphorylation by the GADD34-PP1c phosphatase complex represents a promising strategy for the increase in type 1 collagen production and prevention of UV-induced skin photoaging. In this study, the molecular docking and dynamics simulations, and pharmacophore modeling method were run to investigate a possible binding site as well as binding modes between apigenin, daidzein, asiaticoside, obovatol, and astragaloside IV and PP1c. Through docking study, the possible binding site for these phytochemicals was predicted as the hydrophobic (PP1 substrate binding) groove. The result indicates that PP1 is the significant target of these compounds. Moreover, the 20,000-ps MD simulations present that the binding locations and modes predicted by the docking have been slightly changed considering that the MD simulations proffer more reliable details upon the protein-ligand recognition. The MM-GBSA binding free energy calculations and pharmacophore modeling rationally identify that the highly hydrophobic surfaces/pockets at close proximity of the catalytic core are the most favorable binding locations of the herbal compounds, and that some experimental facts upon a possible mechanism of increase in collagen biosynthesis can be explained. The present study theoretically offers the reliable binding target of the herbal compounds, and therefore helps to understanding the action mechanism for natural small molecules that enhance collagen production. PMID- 30284190 TI - Heterobucephalopsine and prosorhynchine trematodes (Digenea: Bucephalidae) from teleost fishes of Moreton Bay, Queensland, Australia, with the description of two new species. AB - Eight species of the trematode family Bucephalidae Poche, 1907 are reported from teleost fishes in Moreton Bay, Queensland, Australia. Heterobucephalopsis yongi n. sp. is described from Gymnothorax eurostus (Muraenidae); the new form is distinguished from its congeners in the possession of a tiny cirrus-sac relative to body length, the length of the caecum, the position of the mouth and pharynx, and the position of the testes and ovary. Two known species of Dollfustrema Eckmann, 1934, D. durum Nolan, Curran, Miller, Cutmore, Cantacessi & Cribb, 2015 and D. gibsoni Nolan & Cribb, 2010, are reported from Gymnothorax pseudothyrsoideus (Bleeker) (Muraenidae); although both species were described from Australian waters, this represents the first reports from Moreton Bay and G. pseudothyrsoideus. Four species of Prosorhynchus Odhner, 1905 are reported, including one new, P. brayi n. sp., which is described from Epinephelus coioides (Hamilton) (Serranidae); P. brayi n. sp. is distinguished from its congeners in the possession of vitelline follicles in a confluent arc distinctly posterior to a conical rhynchus, uterine coils that do not extend anterior to the vitelline arc, contiguous testes, a cirrus-sac that reaches anteriorly to at least the level of the posterior testis and a short excretory vesicle. Three known species of Prosorhynchus are reported from Australia, for the first time: P. luzonicus Velasquez, 1959 and P. maternus Bray & Justine, 2006 from E. coioides and Prosorhynchus platycephali (Yamaguti, 1934) Srivastava, 1938 from Ambiserrula jugosa (McCulloch) and Inegocia japonica (Cuvier) (Platycephalidae). Skrjabiniella Issaitschikow, 1928 is re-recognised for new specimens of Skrjabiniella uniporus (Ozaki, 1924) n. comb. collected from Conger cinereus Ruppell (Congridae); three additional species of Prosorhynchus are considered members of this genus, two of which are synonymised with S. uniporus. PMID- 30284192 TI - Exhaustive exercise decreases renal organic anion transporter 3 function. AB - This study aimed to investigate the effects of various types of exercise on organic anion transporter 3 (Oat3) function, a major transporter that plays a role in the secretion of a variety of drugs and endogenous compounds. Male Wistar rats were randomly allocated to non-exercise, exhaustive, acute and training exercise groups. The function of Oat3 was assessed by the uptake of [3H]-estrone sulfate ([3H]-ES) into rat renal cortical slices. Acute and training exercises had no effect on [3H]-ES uptake whereas a marked reduction in [3H]-ES uptake occurred immediately after exhaustive exercise. However, the reduction in Oat3 function was gradually recovered at 6 and 24 h after the exercise session. Importantly, the impairment of Oat3 function was associated with a decrease in renal Oat3 protein expression. Our results indicate that exhaustive exercise produces a significant impact on renal organic anion transport function, which in turn could alter the plasma level of drugs and compounds in the body. PMID- 30284194 TI - Additive effect of metastamiR-193b and breast cancer metastasis suppressor 1 as an anti-metastatic strategy. AB - BACKGROUND: It has been reported that enhancing the cellular levels of miR-193b as well as breast cancer-metastasis-suppressor-1 (BRMS1) protein is associated with diminished metastatic characteristics in breast cancer. In view of these facts, as a new therapeutic intervention, we employed a restoration-based strategy using both miR-193b-3p mimic and optimized BRMS1 in the context of a chimeric construct. METHODS: miR-193b-3p and BRMS1 genes were cloned and the resulting plasmids were transfected into the MDA-MB231, MCF-7 and MCF-10A cell lines. microRNA expression levels were assessed by rea time PCR using LNA-primer and protein expression was confirmed by western blot method. Then, apoptosis, MTT, colony formation and invasion assays were carried out. RESULTS: The expression levels of miR-146a, miR-146b and miR-373 were up-regulated, while the miR-520c, miR-335 and miR-10b were down-regulated following the exogenous BRMS1 expression. The exogenous over-expression of BRMS1 was associated with higher amounts of endogenous miR-193b-3p expression and enabled more efficient targeting of the 3'UTR of uPA. Although, miR-193b-3p and BRMS1 are individually capable of suppressing breast cancer cell growth, migration and invasion abilities, their cistronic expression was capable of enhancing the ability to repress the breast cancer cells invasion. CONCLUSIONS: Our results collectively indicated the existence of an additive anti-metastatic effect between miR-193b-3p and BRMS1. Moreover, it has been hypothesized that the exogenous expression of a protein can effect endogenous expression of non-relevant microRNA. Our findings provide new grounds for miR-restoration therapy applications as an amenable anti-metastatic strategy. PMID- 30284193 TI - Psychosocial Mediators of Change and Patient Selection Factors in Oral Immunotherapy Trials. AB - Health-related quality of life (HRQL) is influenced by physiological, psychological, and environmental variables and can be best understood by considering the interactions of factors that cut across multiple levels. One of the most important issues relating to treatment in food allergy is to identify, describe, and define predictors that may contribute to modify HRQL outcomes. The research presented demonstrates that measures of HRQL are able to distinguish key features of known groups (e.g. relating to reaction severity, treatment, allergen type/number, expectation of outcome) and delineate impact on hitherto unknown groups (e.g. relating to personality types and coping styles). This heterogeneity may explain why HRQL or other patient-related outcomes may differ in individuals during, or following any treatment or intervention. Patient-reported outcomes are relatively poorly defined to date. Since HRQL has only been studied in relatively few oral immunotherapy trials to date, primarily looking at caregiver HRQL, it is unclear which factors, measures, or subscales are most predictive of short- and/or long-term treatment outcomes for which type of patient, and which time points for measurement are most informative. A standardised protocol that incorporates HRQL and other relevant patient-related outcome measures and agreed definitions of outcomes would allow for the comparison of efficacy of food allergy treatments between centres, trials, or countries. Further evidence-based research aimed at exploring the effects of interventions on outcomes in food allergy is needed, including the influence of patient and parent factors on protocol design. To this end, it is vital that patient-related outcomes such as improved HRQL are seen as a primary outcome and are measured at multiple intervals during the trial duration and beyond. The creative use of methods and designs (both qualitative and quantitative) to better understand the role of HRQL in immunotherapy treatment trials will enable improved modelling of the costs, risks, and benefits of any treatment. Systematic analysis and modelling of antecedent factors, mediators, and outcomes will be important to boost intervention effects and to maximise the overall benefits of treatment. PMID- 30284196 TI - Size does matter: when a large plastic biliary stent ends up in the root of the mesentery. AB - Duodenal perforations due to biliary stenting migration, although rare, can occur. We report a unique case of duodenal perforation due to a large in length plastic stent with no (or marginal) migration, which ended up in the root of the mesentery, explaining the normal laboratory values and minimal imaging findings observed. Any clinical symptom during the postprocedural period should raise the suspicion of a major complication and prompt quick management decisions. PMID- 30284197 TI - U-turn of uterine arteries: a novel sign pathognomonic of uterine inversion. AB - A uterine inversion occurs when the uterine fundus collapses into the endometrial cavity. It is a rare complication in obstetrics following delivery, and it is even more infrequently encountered in gynecology with the non-puerperal uterus. A submucous fibroid is the most common reported cause of the non-puerperal uterine inversion. If not promptly recognized and treated, uterine inversion may lead to a severe hemorrhagic shock and death. We describe a novel three-dimensional power Doppler feature for the diagnosis of uterine inversion. PMID- 30284198 TI - Severe Biliary Stricture Dilation Using the Soehendra Stent Retriever with a Short-Type Balloon Enteroscope in Patients with Surgically Altered Anatomies. AB - BACKGROUND: Balloon enteroscopy (BE) can be used for endoscopic retrograde cholangiography (ERC) to treat biliary strictures in patients with surgically altered anatomies. However, biliary strictures, including bilioenteric anastomotic strictures, are often very severe and dilation catheters cannot pass through them. The Soehendra stent retriever (SSR) is like a screw drill and can be useful for dilating severe strictures, but the utility of SSR during BE assisted ERC (BE-ERC) is unclear. This study aimed to examine the efficacy and safety of a dilation technique using the SSR during BE-ERC. METHODS: Between 2014 and 2018, 28 patients with surgically altered gastrointestinal anatomies and severe biliary strictures underwent BE-ERC, and the SSR was used for the dilation procedures. We evaluated the technical success, therapeutic success, and adverse event rates associated with SSR dilation. RESULTS: The technical success rate was 93% (26/28). The procedures undertaken on two patients with non-anastomotic strictures failed technically because the SSR was not long enough to reach the strictures. The therapeutic success rate was 96% (25/26) for the patients whose procedures were technically successful. The adverse event rate was 7% (2/28), and the adverse events were mild and improved with conservative management. No bleeding or duct perforations occurred. CONCLUSIONS: Although the indications for using the SSR in patients with non-anastomotic strictures should be considered based on the distance between the tip of the scope and the stricture's location, SSR dilation may be a useful option during BE-ERC if a biliary stricture is very severe.

AB - PURPOSE OF REVIEW: To discuss recent progress in sarcopenia research and to highlight controversies in the field particularly around reaching consensus on a definition of sarcopenia. RECENT FINDINGS: Accordingly, this review begins with a discussion of the increasing awareness of this condition; briefly describes evolving definitions of sarcopenia; suggests a framework for consistent terminology for sarcopenia; discusses outstanding issues in the definition of sarcopenia; and reviews the association between sarcopenia and adverse outcome in older adults. In addition, the role of sarcopenia in other diseases is discussed. The field of sarcopenia continues to hold considerable promise and work continues to resolve outstanding concerns in this field with a unifying consensus definition on the horizon. PMID- 30284199 TI - The Impact of a Multivisceral Resection and Adjuvant Therapy in Locally Advanced Colon Cancer. AB - BACKGROUND: Multivisceral resection for locally advanced colon cancer is mandatory to achieve complete tumor resection. We aimed to determine if local multivisceral resections (LMR) for pT4 and pT3 tumors impact perioperative and long-term oncological outcomes. METHODS: All stage II or III colon cancer patients who had surgery between 2004 and 2014 were identified. We analyzed patients with non-multivisceral resections (NMR) for pT4 tumors vs. pT4-LMR. In addition, outcomes were compared to both NMR and LMR pT3 patients. RESULTS: LMR was performed in 55 (29.7%) of all patients with pT4 tumors and in 48 (8.9%) of all patients with pT3 tumors. The most commonly involved areas of extension were the abdominal wall and the small intestine. Transverse colon cancer was correlated with LMR. Morbidity rates were comparable between NMR and LMR, with the exception of higher rates of blood transfusion and postoperative ileus. Over one third of all pT4-NMR patients developed recurrent disease, which was higher compared to all other groups. Subsequently, overall and disease-specific survival, as well as disease-free survival (DFS), was worse for pT4-NMR, even after adjustment for pTN-staging, adjuvant therapy, and R0 resection. Furthermore, when analyzing only curative resections, radial margin < 1 cm along with nodal disease was independent predictor for worse DFS. Long-term outcomes were comparable between pT4-LMR and pT3 patients. CONCLUSIONS: Multivisceral resection for locally advanced colon cancer preserves long-term oncological outcomes without increased postoperative morbidity. Moreover, LMR in pT3 tumors does not contribute to postoperative morbidity. Our study underlines the feasibility and importance of performing LMR when locally advanced cancer is suspected. PMID- 30284200 TI - Laparoscopic Resection for Adenocarcinoma of the Stomach or Gastroesophageal Junction Improves Postoperative Outcomes: a Propensity Score Matching Analysis. AB - BACKGROUND: Minimally invasive resection for upper gastrointestinal tumors has been associated with favorable results. However, the role of laparoscopic surgery (LS) in the multimodal treatment of patients with advanced adenocarcinoma of the stomach or gastroesophageal junction needs further investigation. METHODS: Clinicopathological data of patients who underwent gastrectomy between 2005 and 2017 were assessed. Outcomes of patients undergoing LS were compared with those of patients treated with a conventional open resection (OR) using a 1:1 propensity score matching analysis. RESULTS: Curative resection for adenocarcinoma of the stomach or gastroesophageal junction was performed in 417 patients during the study period. Beginning in June 2014, the majority of patients underwent LS (n = 72) and they were matched with 72 patients who were treated with an OR. The majority of patients treated with LS (89%) had advanced cancer (UICC stages II and III) and 82% of them received neoadjuvant chemotherapy. LS was significantly associated with a higher number of harvested lymph nodes (26 (9-62) vs. 21 (4-46), P = .007), a lower 90-day major complication rate (13 vs. 26%, P = .035), and a lower length of hospital stay (14 vs. 16 days, P = .001). After a median follow-up time of 32 months, 1-year overall survival rate was higher after LS than after OR (93 vs. 74%, P = .126); however, results did not reach statistical significance. CONCLUSION: LS for adenocarcinoma of the stomach or gastroesophageal junction is feasible and significantly reduces major postoperative morbidity resulting in a reduced length of hospital stay. Therefore, LS should be preferably considered for the curative treatment of patients with these malignancies. PMID- 30284202 TI - Gastric Intussusception Secondary to Fundic Gland Polyposis. PMID- 30284201 TI - Urgent Management of Obstructing Colorectal Cancer: Divert, Stent, or Resect? AB - Despite the availability of effective colorectal cancer (CRC) screening strategies, up to 10% of CRC patients present with obstructive symptoms as the first sign of disease. For patients with acute or subacute malignant obstruction that requires urgent intervention, treatment options include endoscopic stenting as a bridge to surgery, one-stage surgical resection and anastomosis, or diverting ostomy which may or may not be followed by later tumor resection and stoma closure. However, to date, there is no consensus guideline for the optimal approach to manage malignant colorectal obstruction. This article aims to illustrate clinical scenarios in palliative, curative, and potentially curative settings, and delineate the key factors to be considered when making an individualized decision in order to determine the optimal treatment. PMID- 30284204 TI - Development of a Human APOE Knock-in Mouse Model for Study of Cognitive Function After Cancer Chemotherapy. AB - Cancer-related cognitive impairment in breast cancer patients exposed to multi agent chemotherapy regimens is associated with the apolipoprotein E4 (APOE4) allele. However, it is difficult to determine the effects of specific agents on cognitive impairment in human studies. We describe the development of a human APOE knock-in congenic C57BL/6J mouse model to study cancer-related cognitive impairment. Female APOE3 and APOE4 homozygous mice were either left untreated or treated with the most commonly used breast cancer therapeutic agent, doxorubicin. APOE3 and APOE4 mice had similar behaviors in exploratory and anxiety assays, which were affected transiently by doxorubicin treatment. Spatial learning and memory were measured in a Barnes maze: after 4 days of training, control APOE3 and APOE4 mice were able to escape with similar latencies. In contrast, doxorubicin-treated APOE4 mice had markedly impaired learning compared to doxorubicin-treated APOE3 mice at all time points. Voxel-based morphometry of magnetic resonance images revealed that doxorubicin treatment caused significant changes in the cortex and hippocampus of in both APOE3 and APOE4 mouse brains, but the differences were significantly greater in the APOE4 brains. The results indicate that doxorubicin-exposed APOE4 mice recapitulate key aspects of human cancer-related cognitive impairment. These data support the usefulness of this novel preclinical model for future elucidation of the genetic and molecular interactions of APOE genotype with chemotherapy; this model can also allow extension to prospective studies of older mice to study these interactions in the context of aging. PMID- 30284203 TI - Long non-coding RNA MEG3 regulates proliferation, apoptosis, and autophagy and is associated with prognosis in glioma. AB - PURPOSE: Accumulating evidence indicates that dysregulated long noncoding RNAs (lncRNAs) play critical roles in tumorigenesis and cancer progression. LncRNA maternally expressed gene 3 (MEG3) has been shown to be involved in the initiation and development of several cancers, including glioma. However, the clinical prognostic value of MEG3 in glioma has not yet been fully elucidated. METHODS: The expression levels of MEG3 were detected in 79 glioma tissues and adjacent normal brain tissues, as well as, glioma cells and normal human astrocytes by qRT-PCR. Kaplan-Meier and Cox regression methods were utilized for the survival analysis. MTT assay, flow cytometry, and immunofluorescence assay were carried out to detect the impact of MEG3 on glioma cell proliferation, apoptosis, and autophagy. RESULT: The current results showed that MEG3 expression was significantly downregulated in glioma tissues and cell line and negatively correlated with WHO grade in glioma patients. Low MEG3 expression was significantly associated with the advanced WHO grade, low Karnofsky performance score (KPS), IDH wild-type, and tumor recurrence. Patients displaying a low expression of MEG3 contributed to poor overall survival. The downregulated level of MEG3, advanced WHO grade, low KPS, IDH wild-type, and tumor recurrence were independent poor prognostic indicators in glioma patients. The in vitro experiments demonstrated that the MEG3 overexpression remarkably suppressed the proliferation while facilitating apoptosis and autophagy in glioma cells. CONCLUSIONS: These findings indicated a critical role of MEG3 in glioma cell proliferation, apoptosis, and autophagy. Also, the gene was found to be significantly associated with the prognosis in glioma patients. Thus, it might provide a new target for predicting prognosis and therapeutic intervention in glioma. PMID- 30284206 TI - Non-adenomatous sellar lesions: single-centre 10-year experience. AB - OBJECTIVE: A minority of lesions found in the sellar region are non-adenomatous neoplastic, inflammatory, or cystic masses. Our study aims to describe the prevalence and characteristics of these lesions in a multidisciplinary pituitary outpatient clinic. DESIGN: We conducted an observational study which included 36 patients (15.9% of those followed up in this outpatient clinic between 2006 and 2016 who had pituitary surgery) submitted to pituitary surgery with histological results showing a non-adenomatous sellar lesion. We evaluated clinical, radiological, and biochemical (pituitary function) characteristics during the pre operative and post-operative period. RESULTS: Thirty-six patients (50% female) with a mean age of 41.3 +/- 21.9 years and a mean follow-up duration of 8.0 +/- 9.0 years were included. Histologic diagnoses were divided into benign neoplasms (80.6%), malignant neoplasms (11.1%), inflammatory lesions (5.6%), and cystic masses (2.8%). The most common clinical presentation was headache (66.7%) and visual defects (61.1%). Forty-seven percent of patients had at least one pituitary axis insufficiency at the time of diagnosis. In the majority of cases (58.3%), a transsphenoidal approach was used for the initial pituitary surgery. Thirteen patients had more than one pituitary surgery and eight also had radiotherapy. At the time of data retrieval, five patients had no pituitary hormonal insufficiency and 13 patients had some visual defect improvement. CONCLUSIONS: Although rare, non-adenomatous sellar lesions may be associated with significant causes of morbidity, such as hypopituitarism and visual defects, per se or due to the various treatment modalities employed. Moreover, since the lesions are difficult to distinguish from adenomas, these patients require a careful multidisciplinary approach. PMID- 30284205 TI - Sequence Ion Structures and Dissociation Chemistry of Deprotonated Sucrose Anions. AB - We investigate the tandem mass spectrometry of regiospecifically labeled, deprotonated sucrose analytes. We utilize density functional theory calculations to model the pertinent gas-phase fragmentation chemistry of the prevalent glycosidic bond cleavages (B1-Y1 and C1-Z1 reactions) and compare these predictions to infrared spectroscopy experiments on the resulting B1 and C1 product anions. For the C1 anions, barriers to interconversion of the pyranose [alpha-glucose-H]-, C1 anions to entropically favorable ring-open aldehyde terminated forms were modest (41 kJ mol-1) consistent with the observation of a band assigned to a carbonyl stretch at ~ 1680-1720 cm-1. For the B1 anions, our transition structure calculations predict the presence of both deprotonated 1,6 anhydroglucose and carbon 2-ketone ((4S,5S,6R)-4,5-dihydroxy-6 (hydroxymethyl)dihydro-2H-pyran-3(4H)-one) anion structures, with the latter predominating. This hypothesis is supported by our spectroscopic data which show diagnostic bands at 1600, 1674, and 1699 cm-1 (deprotonated carbon 2-ketone structures), and at ~ 1541 cm-1 (both types of structure) and RRKM rate calculations. The deprotonated carbon 2-ketone structures are also the lowest energy product B1 anions. Graphical Abstract ?. PMID- 30284207 TI - A Study of the Activity of Recombinant Mn-Superoxide Dismutase in the Presence of Gold and Silver Nanoparticles. AB - Superoxide dismutase (SOD) is one of the best characterized enzyme maintaining the redox state in the cell. A bacterial expression system was used to produce human recombinant manganese SOD with a His-tag on the C-end of the protein for better purification. In addition, gold and silver nanoparticles were chemically synthesized in a variety of sizes, and then mixed with the enzyme for immobilization. Analysis by dynamic light scattering and scanning transmission electron microscopy revealed no aggregates or agglomerates of the obtained colloids. After immobilization of the protein on AuNPs and AgNPs, the conjugates were analyzed by SDS-PAGE. It was determined that SOD was adsorbed only on the gold nanoparticles. Enzyme activity was analyzed in colloids of the gold and silver nanoparticles bearing SOD. The presence of a nanoparticle did not affect enzyme activity; however, the amount of protein and size of the gold nanoparticle did influence the enzymatic activity of the conjugate. Our findings confirm that active recombinant human superoxide dismutase can be produced using a bacterial expression system, and that the enzyme can be immobilized on metal nanoparticles. The interaction between enzymes and metal nanoparticles requires further investigation. PMID- 30284208 TI - A Fiber Optic Biosensor Based on Hydrogel-Immobilized Enzyme Complex for Continuous Determination of Cholesterol and Glucose. AB - A multiparameter fiber optic biosensor for continuous determination of cholesterol and glucose was developed. This sensor was based on poly(N isopropylacrylamide) (PNIPAAm)-immobilized glucose oxidase (GOx) complex (PIGC) and immobilized cholesterol oxidase (COD). The immobilized COD catalysis to the oxidation of cholesterol and PIGC catalysis to the oxidation of glucose could be performed at different temperatures. Therefore, the sensor could detect cholesterol and glucose continuously by changing temperature. The optimal detection conditions for glucose were achieved with pH 6.5, 30 degrees C, and 10 mg GOx (in 100-mg carrier), and those for cholesterol were achieved with pH 7.5, 33 degrees C, and 25 mg COD (in 250-mg carrier). The sensor has the cholesterol detection range of 20-250 mg/dL and the glucose detection range of 50-700 mg/dL. This biosensor has outstanding repeatability and selectivity, and the detection results of the practical samples are satisfactory. PMID- 30284210 TI - One-Step Enzymatic Synthesis of 1-Tuliposide A Using Tuliposide-Converting Enzyme. AB - 6-Tuliposides A (6-PosA) and B (6-PosB) are major secondary metabolites in tulip (Tulipa gesneriana), having an acyl group at the C-6 position of D-glucose. They serve as precursors of the antimicrobial alpha-methylene-gamma-butyrolactones tulipalins A (PaA) and B (PaB). The conversions of 6-PosA/6-PosB to PaA/PaB are catalyzed by tuliposide-converting enzymes A and B (TCEA and TCEB), respectively. A minor Pos, 1-PosA, which has the acyl group at the C-1 position of D-glucose, has been identified in some wild tulip species, but availability of this compound is limited. Here, by using the TCEs, we established a facile enzymatic process for 1-PosA synthesis from the naturally occurring 1,6-diacyl-glucose type of Pos (PosD and PosF). We first discovered that TCEA and TCEB react preferentially with PosD and PosF, respectively, to form 1-PosA and the corresponding Pa derived from the 6-acyl group, demonstrating that the TCEs specifically acted on the 6-acyl group, but not the 1-acyl group, of the substrates. Using TCEB, 300 mg of PosF was completely converted to 1-PosA and PaB in 10 min at room temperature. Then, 160 mg of 1-PosA (75% molar yield) was purified by column chromatography. This one-step enzymatic process dramatically improves accessibility to 1-PosA. PMID- 30284209 TI - Citric Acid Production from Acorn Starch by Tannin Tolerance Mutant Aspergillus niger AA120. AB - In this study, acorn starch was investigated as a new material for fermenting production of citric acid by using a tannin tolerance mutant strain Aspergillus niger AA120. The mutant A. niger AA120 was obtained by initially atmospheric pressure plasma at room temperature (ARTP) mutagenesis and then tannin gradient domestication. ARTP experiments showed that a "double-saddle" shape of survival rate curve was achieved, and a positive mutation rate of 63.6% was reached by setting the implantation time of mutagenesis to 100 s. In contrast to the original stain at the presence of 20.0 g/L tannin in the medium, the selected mutant A. niger AA120 exhibits an increase of biomass by 43.76% to 32.9 g/L, and citric acid production capacity by 20.34% to 130.8 g/L, with 8% (w/w) of inoculation quantity, an initial pH of 6.2 and shaking speed of 250 r/min. In this work, we present a referable method for the mutagenesis screening of the A. niger, and the application of acorn starch as a new raw material for the development of the citric acid industry. PMID- 30284211 TI - LAB: Linguistic Annotated Bibliography - a searchable portal for normed database information. AB - This article presents the Linguistic Annotated Bibliography (LAB) as a searchable Web portal to quickly and easily access reliable database norms, related programs, and variable calculations. These publications were coded by language, number of stimuli, stimuli type (i.e., words, pictures, symbols), keywords (i.e., frequency, semantics, valence), and other useful information. This tool not only allows researchers to search for the specific type of stimuli needed for experiments but also permits the exploration of publication trends across 100 years of research. Details about the portal creation and use are outlined, as well as various analyses of change in publication rates and keywords. In general, advances in computational power have allowed for the increase in dataset size in the recent decades, in addition to an increase in the number of linguistic variables provided in each publication. PMID- 30284212 TI - Beyond frequency counts: Novel conceptual recurrence analysis metrics to index semantic coordination in team communications. AB - Semantic alignment is a key process underlying interpersonal and team communication. However, semantic similarity is difficult to quantify, and statistical approaches designed to measure it often rely on methods that make the identification of the relative importance of key words difficult. This study outlines how conceptual recurrence analysis (CRA) can address these issues and can be used to detect conceptual structure in interpersonal communication. We developed several novel CRA metrics to analyze communication data reported previously by Mancuso, Finomore, Rahill, Blair, and Funke (Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 58, 405-409, 2014), gathered from teams who worked cooperatively on a logic puzzle under different cognitive biasing contexts. CRA, like other measures of semantic coordination, relies on parameters whose values affect estimates of semantic alignment. We evaluated how the dimensionality of semantic spaces affects metrics quantifying the conceptual similarity of communicative exchanges, and whether metrics calculated from top down, a priori semantic spaces or bottom-up semantic spaces empirically derived from each data set were more sensitive to biasing context. We found that the novel CRA measures were sensitive to manipulations of cognitive bias, and that higher-dimensional, bottom-up semantic spaces generally yielded more sensitivity to the experimental manipulations, though when the communication was evaluated with respect to specific key concepts, lower-dimensional, top-down spaces performed nearly as well. We conclude that CRA is sensitive to experimental manipulations in ways consistent with prior findings and that it presents a customizable framework for testing predictions about interpersonal communication patterns and other linguistic exchanges. PMID- 30284213 TI - Remote associates test: An empirical proof of concept. AB - Associative processes play a major role in research on human thinking, especially creativity. One of the most influential models emphasizing associative processes in creative thinking was introduced by Mednick (Psychological Review, 69, 220 232, 1962), who developed the remote associates test (RAT) as a domain-general measure of individual differences in associative hierarchies. Although S. Mednick's theoretical framework has recently regained much attention, the fundamental psychometric assumptions and underlying cognitive processes involved in the RAT remain controversial. We carried out two studies to evaluate these issues. In the first, a confirmatory factor analysis showed that a single latent factor accounted for the ability to solve RAT problems, despite their psycholinguistic heterogeneity. Subsequent regression analyses indicated that cue solution associative remoteness substantially determined the difficulty of RAT problems, accounting for about 80% of variance. In the second study we used a newly developed associative chain test (ACT), which assesses lexical-semantic and executive measures during associative processing. We found that performance on the RAT was related to lexical-semantic (higher response remoteness and lower response commonness) but not to executive (response inhibition and switching) ACT measures. Overall, our findings indicate that the RAT reflects a coherent ability to access and combine remote elements in lexical-semantic and associative networks without considerably engaging executive attention. Although the validity and utility of the RAT was supported, we propose that the ACT provides a more complex and fine-grained tool for the assessment of associative processing. PMID- 30284214 TI - Pharmacoepidemiologic Evaluation of Birth Defects from Health-Related Postings in Social Media During Pregnancy. AB - INTRODUCTION: Adverse effects of medications taken during pregnancy are traditionally studied through post-marketing pregnancy registries, which have limitations. Social media data may be an alternative data source for pregnancy surveillance studies. OBJECTIVE: The objective of this study was to assess the feasibility of using social media data as an alternative source for pregnancy surveillance for regulatory decision making. METHODS: We created an automated method to identify Twitter accounts of pregnant women. We identified 196 pregnant women with a mention of a birth defect in relation to their baby and 196 without a mention of a birth defect in relation to their baby. We extracted information on pregnancy and maternal demographics, medication intake and timing, and birth defects. RESULTS: Although often incomplete, we extracted data for the majority of the pregnancies. Among women that reported birth defects, 35% reported taking one or more medications during pregnancy compared with 17% of controls. After accounting for age, race, and place of residence, a higher medication intake was observed in women who reported birth defects. The rate of birth defects in the pregnancy cohort was lower (0.44%) compared with the rate in the general population (3%). CONCLUSIONS: Twitter data capture information on medication intake and birth defects; however, the information obtained cannot replace pregnancy registries at this time. Development of improved methods to automatically extract and annotate social media data may increase their value to support regulatory decision making regarding pregnancy outcomes in women using medications during their pregnancies. PMID- 30284215 TI - Surveillance of Drug Safety During Pregnancy: Insight in Current International Activities, Future Intentions and Need for Support of National Pharmacovigilance Centres. AB - INTRODUCTION: Surveillance of drug safety during pregnancy is a special interest of pharmacovigilance (PV). The role that national PV centres take in this field is, however, unclear. AIM: The aim of this study was to provide insight into current activities, future intentions and need for support of national PV centres in the field of drug safety during pregnancy. METHOD: A web-based questionnaire was used to ask PV centres about their current activities concerning the surveillance of drug safety during pregnancy, their intentions to implement or improve activities and need for support. For these three main topics, questions were posed about spontaneous adverse drug reaction (ADR) reporting, additional activities to obtain information, signal detection and informing healthcare professionals and the public. RESULTS: The questionnaire was sent to PV centres of 172 countries. Response was 40%. In general, the PV centres received limited numbers of reports of ADRs in the (unborn) child, related to drug exposure during pregnancy. Signal detection in pregnancy cases is carried out by 8 out of 58 PV centres (13.5%). Most PV centres mention they have intentions to implement or improve activities, mainly for spontaneous reporting (69.4%) and methods for signal detection (67.2%). Support was needed for all topics of the questionnaire. CONCLUSION: Current activities of national PV centres concerning drug safety during pregnancy are limited. The majority of PV centres are, however, willing to improve or implement activities. Programmes should be set up in order to support and stimulate PV centres with these activities. The aim of all these activities is to increase knowledge about the safety of drugs during pregnancy. PMID- 30284216 TI - Psychometric properties of the Spanish version of the Experience of Caregiving Inventory (ECI) among caregivers of individuals with an eating disorder. AB - PURPOSE: The aim of this study was to examine the psychometric properties of the Spanish version of the Experience of Caregiving Inventory (ECI-S), which is designed to assess the caregiver's appraisal of the impact of caring for a relative with a serious mental illness. METHODS: A cross-sectional study was conducted among 320 caregivers of a relative with an eating disorder to examine: (a) descriptive statistics; (b) internal consistency reliability; (c) the fit of the original ten-factor structure of the ECI through exploratory factor analysis, using a semi-confirmatory approach, for each subscale individually, and (d) concurrent validity. A total of 307 caregivers completed the scale. RESULTS: Reliability of the ECI subscales scores was acceptable (alpha = 0.63-0.89). Results replicated the original ten-factor structure of the instrument. The concurrent validity was supported by correlations of the ECI-negative subscale with psychological distress (GHQ-12, 0.43), and with depression and anxiety (HADS, 0.48 and 0.49, respectively). CONCLUSIONS: The Spanish version of the ECI (ECI-S) demonstrated good psychometric properties in terms of validity and reliability that were similar to the original version. It is an acceptable and valid instrument for assessing the impact on family members of caring for a relative with an eating disorder and can be recommended for use in clinical settings in Spain.

AB - PURPOSE: To investigate the effects of metabolic abnormalities, hyperandrogenemia and ovulation induction by clomiphene/acupuncture on liver function parameters among women with polycystic ovary syndrome (PCOS). METHODS: This is a secondary analysis of a randomized controlled trial. All 1000 subjects were diagnosed as PCOS by modified Rotterdam criteria. Liver function parameters, metabolic panel and hormone profile were measured at baseline and after treatment. The relationship between liver parameters with metabolic, hormonal parameters and ovulation induction was examined. RESULTS: PCOS women with metabolic syndrome had higher liver enzyme levels but lower bilirubin and bile acid levels than without. PCOS women with hyperandrogenemia had higher liver enzyme, bilirubin levels than without. Correlation analyses showed that worsening of metabolic parameters was associated with higher liver enzyme levels but lower bilirubin and bile acid levels, while increased androgen levels were associated with higher liver enzyme, bilirubin and bile acid levels. Ovulation induction with clomiphene citrate could decrease bilirubin and bile acid levels, while acupuncture had no obvious effect on liver function. CONCLUSIONS: Among PCOS women, metabolic abnormalities and hyperandrogenemia impaired different liver function parameters. Clomiphene could decrease the bilirubin and bile acid levels while acupuncture had no obvious effect on liver function. PMID- 30284223 TI - Quantitative proteomics analysis of sporadic parathyroid adenoma tissue samples. AB - OBJECTIVE: Molecular pathogenesis of parathyroid tumors is incompletely understood. Identification of novel molecules and understanding their role in parathyroid tumorigenesis by proteomics approach would be informative with potential clinical implications. METHOD: Adenomatous (n = 5) and normal (n = 2) parathyroid tissue lysates were analyzed for protein profile by LC-MS/MS method and the proteins were classified using bioinformatics tools such as PANTHER and toppfun functional enrichment tool. Identified proteins were further validated by western blotting and qRT-PCR (n = 20). RESULT: Comparative proteomics analysis revealed that a total of 206 proteins (74 upregulated and 132 downregulated) were differentially expressed (>= twofold change) in adenomas. Bioinformatics analysis revealed that 48 proteins were associated with plasma membrane, 49 with macromolecular complex, 39 were cytoplasm, 38 were organelle related, 21 were cell junction and 10 were extracellular proteins. These proteins belonged to a diverse protein family such as enzymes, transcription factors, cell signalling, cell adhesion, cytoskeleton proteins, receptors, and calcium-binding proteins. The major biological processes predicted for the proteins were a cellular, metabolic and developmental process, cellular localization, and biological regulation. The differentially expressed proteins were found to be associated with MAPK, phospholipase C (PLC) and phosphatidylinositol (PI) signalling pathways, and with chromatin organization. Western blot and qRT-PCR analysis of three proteins (DNAJC2, ACO2, and PRDX2) validated the LC-MS/MS findings. CONCLUSION: This exploratory study demonstrates the feasibility of proteomics approach in finding the dysregulated proteins in benign parathyroid adenomas, and our preliminary results suggest that MAPK, PLC and PI signalling pathways and chromatin organization are involved in parathyroid tumorigenesis. PMID- 30284224 TI - Fasting glucagon-like peptide 1 concentration is associated with lower carbohydrate intake and increases with overeating. AB - PURPOSE: Glucagon-like peptide 1 (GLP-1) is an incretin hormone that appears to play a major role in the control of food intake. The aim of this investigation was to evaluate and quantify the association of circulating GLP-1 concentration with ad libitum total calorie and macronutrient intake. METHODS: One-hundred and fifteen individuals (72 men) aged 35 +/- 10 years were admitted for an inpatient study investigating the determinants of energy intake. Ad libitum food intake was assessed during 3 days using a reproducible vending machine paradigm. Fasting plasma GLP-1 concentrations were measured on the morning of the first day and on the morning of the fourth day after ad libitum feeding. RESULTS: Plasma GLP-1 concentrations increased by 14% after 3 days of ad libitum food intake. Individuals overate on average 139 +/- 45% of weight-maintaining energy needs. Fasting plasma GLP-1 on day 1 was negatively associated with carbohydrate intake (r = - 0.2, p = 0.03) and with daily energy intake from low fat-high simple sugar (r = - 0.22, p = 0.016). CONCLUSION: Higher plasma GLP-1 concentrations prior to ad libitum food intake were associated with lower carbohydrate intake and lower simple sugar ingestion, indicating a possible role of the GLP-1 in the reward pathway regulating simple sugar intake. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00342732. PMID- 30284222 TI - Genome-wide association analysis suggests novel loci for Hashimoto's thyroiditis. AB - PURPOSE: Hashimoto's thyroiditis (HT) is the most common form of autoimmune thyroid diseases. Current knowledge of HT genetics is limited, and not a single genome-wide association study (GWAS) focusing exclusively on HT has been performed to date. In order to decipher genetic determinants of HT, we performed the first GWAS followed by replication in a total of 1443 individuals from Croatia. METHODS: We performed association analysis in a discovery cohort comprising 405 cases and 433 controls. We followed up 13 independent signals (P < 10-5) in 303 cases and 302 controls from two replication cohorts and then meta analyzed results across discovery and replication datasets. RESULTS: We identified three variants suggestively associated with HT: rs12944194 located 206 kb from SDK2 (P = 1.8 * 10-6), rs75201096 inside GNA14 (P = 2.41 * 10-5) and rs791903 inside IP6K3 (P = 3.16 * 10-5). Genetic risk score (GRS), calculated using risk alleles of these loci, accounted for 4.82% of the total HT variance, and individuals from the top GRS quartile had 2.76 times higher odds for HT than individuals from the lowest GRS quartile. CONCLUSIONS: Although discovered loci are implicated with susceptibility to HT for the first time, genomic regions harboring these loci exhibit good biological candidacy due to involvement in the regulation of the thyroid function and autoimmunity. Additionally, we observe genetic overlap between HT and several related traits, such as hypothyroidism, Graves' disease and TPOAb. Our study adds a new knowledge of underlying HT genetics and sets a firm basis for further research. PMID- 30284221 TI - Treating varicocele in 2018: current knowledge and treatment options. AB - PURPOSE: Varicocele is defined as a state of varicosity and tortuosity of the pampiniform plexus around the testis caused by retrograde blood flow through the internal spermatic vein. The prevalence of clinically relevant varicocele ranges from 5 to 20% in the male population and is often associated with infertility and reduction of sperm quality. In this review, the pathophysiology and clinical aspects of varicocele are reviewed along with therapeutic options and treatment effects on sperm parameters and fertility both in adult and in pediatric/adolescent subjects. METHODS: We conducted a Medline and a PubMed search from 1965 to 2018 to identify publications related to varicocele clinical aspects, treatment procedures and treatment outcomes. Keywords used for the search were: "varicocele", "varicocelectomy", "sclerotherapy", "male infertility", "subfertility", and "semen abnormalities". RESULTS: Data from a large number of studies in adolescent and adult males indicate that varicocele correction improves semen parameters in the majority of patients, reducing oxidative stress and improving sperm nuclear DNA integrity either with surgical or percutaneous approach. CONCLUSIONS: Varicocele repair seems to represent a cost-effective therapeutic option for all males (both adolescent and adults) with a clinical varicocele in the presence of testicular hypotrophy, worsening sperm alterations or infertility. On the other hand, some investigators questioned the role of varicocelectomy in the era of assisted reproduction. Thus, a better understanding of the pathophysiology of varicocele-associated male subfertility is of paramount importance to elucidating the deleterious effects of varicocele on spermatogenesis and possibly formulating new treatment strategies.

AB - Obesity has become a major health concern in modern times, as it significantly increases the risk for the development of cardiovascular diseases, type 2 diabetes mellitus, and some types of cancer. The obesity epidemic has brought considerable attention to the molecular mechanisms through which adipocyte secreted adipokines regulate physiological processes involved in metabolic and inflammatory diseases. Among them, leptin is considered as one of the principal regulators of a variety of physiological processes, including appetite and energy metabolism, through its binding to a variety of receptors and in particular by signaling through the long isoform receptor ObRb. Leptin signaling in the brain via ObRb plays an important role in the regulation of appetite and food intake, and involves several signaling pathways that either upregulate or attenuate leptin's anorexigenic response. This review describes ObRb-dependent, leptin induced signaling pathways implicated in the control of appetite and energy metabolism in the organism, based on current information from animal models. PMID- 30284226 TI - Role of Cerium Oxide Nanoparticles in a Paraquat-Induced Model of Oxidative Stress: Emergence of Neuroprotective Results in the Brain. AB - Paraquat (PQ), as a widely used herbicide, enhances the formation of free radicals and oxidative stress. Cerium oxide nanoparticles (CeNPs) are one of the most utilized and effective nanoparticles having strong antioxidative properties and inhibiting free radicals. Here, we aimed to investigate the effects of CeNPs on brain oxidative toxic stress injury induced with PQ. The male rats were treated intraperitoneally daily with PQ (50 mg/kg/day) and CeNPs (15, 30, and 60 mg/kg/day) alone or in combination for 2 weeks. After treatments, the brain tissue samples were collected. Oxidative toxic stress biomarkers including lipid peroxidation (LPO), total antioxidant capacity (TAC), and total thiol molecules (TTM) as well as DNA damage and caspase-3 levels were measured. Moreover, the mRNA expression levels of Nestin and Neurod1 were assayed. Our results showed that PQ has significantly increased brain LPO, DNA damage, and caspase-3 levels and further reduced TAC and TTM contents, as well as expression levels of Nestin and Neurod1, compared with the control group (injection of saline). CeNPs (15- and 30-mg/kg doses) in groups co-administered with PQ significantly ameliorated the LPO, DNA damage, and caspase-3 levels while increasing TAC and TTM contents as well as enhancing Nestin and Neurod1 mRNA expression levels in the brain samples (P < 0.05). These findings suggest a neuroprotective and antioxidant role for CeNPs in PQ-induced brain injury. However, further studies are required to clarify its clinical/pharmacological significance. PMID- 30284228 TI - OIP5 Expression Sensitize Glioblastoma Cells to Lomustine Treatment. AB - Glioblastoma (GBM) is an incurable disease ranked among the deadliest solid cancers worldwide. A better understanding on the molecular aspects of this malignancy could contribute to the development of new treatment strategies and help to improve survival rates. Previously, our group had shown that GBM patients expressing the cancer/testis antigen Opa Interacting Protein 5 (OIP5) present a longer survival period than the OIP5-negative group. The main goal of this study was to evaluate the OIP5 contribution to GBM tumorigenesis and assess the role of OIP5 in GBM cell response to lomustine, an alkylating agent used in the treatment of this malignancy. So, the effect of OIP5 knockdown was evaluated in A172 and T98G GBM cell lines. Our results demonstrated that downregulation of the OIP5 stimulates glioma cell viability and inhibits cell death-induced necrosis prompted by lomustine. In conclusion, our data shows that OIP5 expression in GBM cells seems to be able to enhance lomustine cytotoxic effects, reinforcing that this gene is a potential therapeutic target and putative molecular biomarker for treatment response in GBM. PMID- 30284227 TI - Quinolinic Acid-Induced Huntington Disease-Like Symptoms Mitigated by Potent Free Radical Scavenger Edaravone-a Pilot Study on Neurobehavioral, Biochemical, and Histological Approach in Male Wistar Rats. AB - In this study, we demonstrated for the first time the neuroprotective role of edaravone (Eda) (5 and 10 mg/kg b.w.), a potent free radical scavenger against the unilateral stereotaxic induction of quinolinic acid (QA) (300 nm/4 MUl saline)-induced Huntington disease (HD)-like symptoms in behavioral, biochemical, and histological features in male Wistar rats striatum. QA induction, which mimics the early stage of HD, commonly causes oxidative stress to the cell and decreases the antioxidant defense mechanism by altering the level of lipid peroxidation (LPO), protein carbonyls, and nitrate concentration (NO) and the activities of glutathione family enzymes (GPx, GST, GR) and acetyl choline esterase concentration (AChE) which was found to be ameliorated by Eda treatment in both the tested doses 5 and 10 mg/kg b.w. in the significance of P < 0.05 and P < 0.01, respectively. Finally histopathological analysis by hematoxylin and eosin stain concluded the promising neurodefensive role of Eda in rat striatum at the dosage of 10 mg/kg b.w., with the decreased tissue damage and the number of damaged granular cells when compared to QA-induced groups. PMID- 30284229 TI - The Independent and Combined Effects of Omega-3 and Vitamin B12 in Ameliorating Propionic Acid Induced Biochemical Features in Juvenile Rats as Rodent Model of Autism. AB - Metabolites of proper fatty acids modulate the inflammatory response and are essential for normal brain development; equally, abnormal fatty acid metabolism plays a critical role in the pathology of autism. Currently, dietary supplements are often used to improve the core symptoms of Autism spectrum disorder (ASD). The present study analyzed the effects of orally supplemented omega-3 (omega-3) and vitamin B12 on ameliorating oxidative stress and impaired lipid metabolism in a propionic acid (PPA)-induced rodent model of autism, together with their effect on the gut microbial composition, where great fluctuations in the bacterial number and strains were observed; interestingly, polyunsaturated fatty acids such as omega-3 induced higher growth of the gram-positive bacterium Staphylococcus aureus and decreased the survival rates of Clostridia sp. as well as other enteric bacterial strains. Thirty-five young male western albino rats were divided into five equal groups. The first group served as the control; the second group was given an oral neurotoxic dose of PPA (250 mg/kg body weight/day) for 3 days. The third group received an oral dose of omega-3 (200 mg/kg body weight/day) for 30 days after the 3-day PPA treatment. Group four was given an oral dose of vitamin B12 (16.7 mg/kg/day) for 30 days after PPA treatment. Finally, group five was given a combination of both omega-3 and vitamin B12 at the same dose for the same duration after PPA treatment. Biochemical parameters related to oxidative stress and impaired fatty acid metabolism were investigated in the brain homogenates of each group. The effects of the dietary supplements on the gut microbiota were also observed. The PPA-treated autistic model expressed significantly higher levels of lipid peroxides and 5-lipoxygenase (5-LOX) and significantly less glutathione (GSH), glutathione S-transferase (GST), and cyclooxygenase 2 (COX2) than the control group. However, a remarkable amelioration of most of the impaired markers was observed with oral supplementation with omega-3 and vitamin B12, either alone or in combination. Our results concluded that impairment at various steps of the lipid metabolic pathways may contribute to the development of autism; however, supplementation with omega-3 and vitamin B12 can result in a positive therapeutic effect. PMID- 30284230 TI - Hydrogen peroxide-induced mitophagy contributes to laryngeal cancer cells survival via the upregulation of FUNDC1. AB - PURPOSE: The purpose of our study was to investigate an underlying mechanism that hydrogen peroxide-induced mitophagy contributed to laryngeal cancer cells survivals under oxidative stress condition. METHODS: Tumor tissue and serum samples were collected from patients with laryngeal cancer. The Hep2 cell, a human laryngeal carcinoma cell, was used in in vitro experiments. The levels of lipid peroxidation were analyzed by ELISA. Knockdown of FUNDC1 was performed by RNAi. The changes of target proteins were determined by qRT-PCR and western blot. The cells were analyzed for changes in proliferation using cell counting kit-8 and mitophagy by the mitochondrial membrane potential assay and transmission electron microscopy. RESULTS: FUNDC1 in laryngeal cancer tissues were relative to the levels of lipid peroxidation in laryngeal cancer patients, which suggested that FUNDC1 was associated with the status of oxidative stress in the laryngeal cancer patients. Hydrogen peroxide significantly induced the elevation of FUNDC1, a mitophagic factor, in a time- and dose-dependent manner in laryngeal cancer cells, which was dependent on ERK signal activation. Knockdown of FUNDC1 by the siRNA attenuated the survival of laryngeal cancer cells under hydrogen peroxide stimulation. Moreover, the elevated FUNDC1 was required for the occurrence of mitophagy under hydrogen peroxide stimulation, which was identified by transmission electron microscopy, the alterations of mitochondrial permeability transition and the specific mitochondrial protein, hsp60. Inhibition of mitophagy with cyclosporine A could also effectively attenuate the laryngeal cancer cells survival under hydrogen peroxide stimulation. CONCLUSIONS: Hydrogen peroxide upregulated the expression of FUNDC1 through the activation of ERK1/2 signal to trigger a mitophagic response, giving laryngeal cancer cells a befit for survival. These findings suggested that FUNDC1 might be a potential target for the treatment of laryngeal cancer accompanied with high lipid peroxidation status.

PMID- 30284232 TI - Clinical management of cutaneous adverse events in patients on targeted anticancer therapies and immunotherapies: a national consensus statement by the Spanish Academy of Dermatology and Venereology and the Spanish Society of Medical Oncology. AB - Progress in the understanding of many tumors has enabled the development of new therapies, such as those targeted at specific molecules involved in cell growth (targeted therapies) or intended to modulate the immune system (immunotherapy). However, along with the clinical benefit provided by these new treatments, new adverse effects have also appeared. Dermatological toxicities such as papulopustular eruptions, xerosis, and pruritus are common with EGFR inhibitors. Other adverse effects have also been described with PDGFR, BCR-ABL, and MAPK tyrosine kinase inhibitors, antiangiogenic drugs, and inhibitors at immune checkpoints such as CTLA-4 and PD-1/PD-L1. Onset of these adverse effects often causes dose reductions and/or delays in administering the prescribed therapy, which can affect patient survival and quality of life. It is, therefore, important to prevent the occurrence of these adverse effects, or to treat unavoidable ones as soon as possible. This requires cooperation between medical oncologists and dermatologists. This article reviews the various dermatological toxicities associated with targeted therapies and immunotherapies, along with their diagnosis and therapeutic management. PMID- 30284233 TI - Re-irradiation of recurrent glioblastoma as part of a sequential multimodality treatment concept. AB - PURPOSE: The aim of this retrospective study was to evaluate survival outcomes in well-performing, mainly, young patients receiving a sequence of all available therapeutic options for relapsed glioblastoma, including re-irradiation. METHODS: We performed a retrospective analysis of 27 patients irradiated twice for glioblastoma between 2008 and 2016. In the first line, all had surgical treatment of the tumor followed by radiotherapy with a total dose of 60 Gy and temozolomide. All re-irradiated patients were treated with a total dose of 36 Gy in 12 fractions. The endpoints were death from glioblastoma or any cause, and toxicity after re-irradiation. RESULTS: The median follow-up of survivors was 35.6 months. At the time of analysis, 25 patients had died. The median time between first and second radiotherapy was 18.9 months (6.1-58.4). Re-irradiation was performed at different time points of first, second and third progression. The median overall survival after first diagnosis was 39.2 months. Five years after first surgery, nearly 20% of the patients were alive. CONCLUSION: Carefully planned re-irradiation of the brain is a safe therapy for recurrent glioblastoma. Younger and well-performing patients benefit from all available therapy options. Every patient should be discussed in a multidisciplinary setting at each time point of tumor progression. Further prospective studies are needed to define the optimal time, dose and volume of re-irradiation. PMID- 30284235 TI - Subjective sleep impairment and affective symptoms in frail elderly.

PMID- 30284234 TI - Risk of malnutrition and emotional distress as factors affecting health-related quality of life in patients with resected cancer. AB - INTRODUCTION: This study analyzes the prevalence of malnutrition, depression, anxiety, and somatization and which factor has the biggest effect on quality of life (QoL) in individuals with resected cancer. METHODS: A prospective study was conducted among 747 participants. Participants completed the EORTC-QLQ30, MST, and BSI-18 questionnaires. RESULTS: Prevalence for risk of malnutrition, depression, anxiety, and somatization were 36.4%, 35.5%, 35.2%, and 48.8%, respectively. Hierarchical multiple regression analyses revealed that malnutrition risk, somatization, depression, and anxiety accounted for 50.8% of the variance in functional scale, 45.3% in symptom scale, and 52.2% in global health. Malnutrition, somatization, depression, and anxiety displayed high explanatory power on all health-related QoL (HRQoL) scales. CONCLUSION: The risk of malnutrition and psychological symptoms is strongly associated with HRQoL in cancer patients; thus, medical oncologists should develop effective interventions that contribute to lowering the risk of malnutrition and psychological distress, thereby improving subjects' HRQoL before initiating adjuvant chemotherapy.

PMID- 30284237 TI - Medication adherence, costs, and ER visits of nurse practitioner and primary care physician patients: Evidence from three cohorts of Medicare beneficiaries. AB - OBJECTIVE: To compare medication adherence, cost, and utilization in Medicare beneficiaries attributed to nurse practitioners (NP) and primary care physicians (PCP). DATA: Medicare Part A, B, and D claims and beneficiary summary file data, years 2009-2013. STUDY DESIGN: We used propensity score-weighted analyses combined with logistic regression and generalized estimating equations to test differences in good medication adherence (proportion of days covered (PDC >0.8); office-based and specialty care costs; and ER visits. DATA EXTRACTION: Beneficiaries with prescription claims for anti-diabetics, renin-angiotensin system antagonists (RASA), or statins. PRINCIPAL FINDINGS: There were no differences in good medication adherence (PDC >0.8) between NP and PCP attributed beneficiaries taking anti-diabetics or RASA. Beneficiaries taking statins had a slightly higher probability of good adherence when attributed to PCPs (74.6% vs 75.5%; P < 0.05). NP attributed beneficiaries had lower office-based and specialty care costs and were less likely to experience an ER visit across all three medication cohorts (P < 0.01). CONCLUSIONS: Examining the impact of NP and PCP provided care on outcomes beyond the primary care setting is important to the Medicare program in general but will also help practices seeking to meet benchmarks under alternative payment models that incentivize higher quality and lower costs. PMID- 30284239 TI - Preoperative radiotherapy and curative surgery for the management of localised rectal carcinoma. AB - BACKGROUND: This is an update of the original review published in 2007.Carcinoma of the rectum is a common malignancy, especially in high income countries. Local recurrence may occur after surgery alone. Preoperative radiotherapy (PRT) has the potential to reduce the risk of local recurrence and improve outcomes in rectal cancer. OBJECTIVES: To determine the effect of preoperative radiotherapy for people with localised resectable rectal cancer compared to surgery alone. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library; Issue 5, 2018) (4 June 2018), MEDLINE (Ovid) (1950 to 4 June 2018), and Embase (Ovid) (1974 to 4 June 2018). We also searched ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP) for relevant ongoing trials (4 June 2018). SELECTION CRITERIA: We included randomised controlled trials comparing PRT and surgery with surgery alone for people with localised advanced rectal cancer planned for radical surgery. We excluded trials that did not use contemporary radiotherapy techniques (with more than two fields to the pelvis). DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the 'Risk of bias' domains for each included trial, and extracted data. For time-to-event data, we calculated the Peto odds ratio (Peto OR) and variances, and for dichotomous data we calculated risk ratios (RR) using the random-effects method. Potential sources of heterogeneity hypothesised a priori included study quality, staging, and the use of total mesorectal excision (TME) surgery. MAIN RESULTS: We included four trials with a total of 4663 participants. All four trials reported short PRT courses, with three trials using 25 Gy in five fractions, and one trial using 20 Gy in four fractions. Only one study specifically required TME surgery for inclusion, whereas in another study 90% of participants received TME surgery.Preoperative radiotherapy probably reduces overall mortality at 4 to 12 years' follow-up (4 trials, 4663 participants; Peto OR 0.90, 95% CI 0.83 to 0.98; moderate-quality evidence). For every 1000 people who undergo surgery alone, 454 would die compared with 45 fewer (the true effect may lie between 77 fewer to 9 fewer) in the PRT group. There was some evidence from subgroup analyses that in trials using TME no or little effect of PRT on survival (P = 0.03 for the difference between subgroups).Preoperative radiotherapy may have little or no effect in reducing cause-specific mortality for rectal cancer (2 trials, 2145 participants; Peto OR 0.89, 95% CI 0.77 to 1.03; low-quality evidence).We found moderate quality evidence that PRT reduces local recurrence (4 trials, 4663 participants; Peto OR 0.48, 95% CI 0.40 to 0.57). In absolute terms, 161 out of 1000 patients receiving surgery alone would experience local recurrence compared with 83 fewer with PRT. The results were consistent in TME and non-TME studies.There may be little or no difference in curative resection (4 trials, 4673 participants; RR 1.00, 95% CI 0.97 to 1.02; low-quality evidence) or in the need for sphincter sparing surgery (3 trials, 4379 participants; RR 0.99, 95% CI 0.94 to 1.04; I2 = 0%; low-quality evidence) between PRT and surgery alone.Low-quality evidence suggests that PRT may increase the risk of sepsis from 13% to 16% (2 trials, 2698 participants; RR 1.25, 95% CI 1.04 to 1.52) and surgical complications from 25% to 30% (2 trials, 2698 participants; RR 1.20, 95% CI 1.01 to 1.42) compared to surgery alone.Two trials evaluated quality of life using different scales. Both studies concluded that sexual dysfunction occurred more in the PRT group. Mixed results were found for faecal incontinence, and irradiated participants tended to resume work later than non-irradiated participants between 6 and 12 months, but this effect had attenuated after 18 months (low-quality evidence). AUTHORS' CONCLUSIONS: We found moderate-quality evidence that PRT reduces overall mortality. Subgroup analysis did not confirm this effect in people undergoing TME surgery. We found consistent evidence that PRT reduces local recurrence. Risk of sepsis and postsurgical complications may be higher with PRT.The main limitation of the findings of the present review concerns their applicability. The included trials only assessed short-course radiotherapy and did not use chemotherapy, which is widely used in the contemporary management of rectal cancer disease. The differences between the trials regarding the criteria used to define rectal cancer, staging, radiotherapy delivered, the time between radiotherapy and surgery, and the use of adjuvant or postoperative therapy did not appear to influence the size of effect across the studies.Future trials should focus on identifying participants that are most likely to benefit from PRT especially in terms of improving local control, sphincter preservation, and overall survival while reducing acute and late toxicities (especially rectal and sexual function), as well as determining the effect of radiotherapy when chemotherapy is used and the optimal timing of surgery following radiotherapy. PMID- 30284240 TI - Psychological interventions for needle-related procedural pain and distress in children and adolescents. AB - BACKGROUND: This is the second update of a Cochrane Review (Issue 4, 2006). Pain and distress from needle-related procedures are common during childhood and can be reduced through use of psychological interventions (cognitive or behavioral strategies, or both). Our first review update (Issue 10, 2013) showed efficacy of distraction and hypnosis for needle-related pain and distress in children and adolescents. OBJECTIVES: To assess the efficacy of psychological interventions for needle-related procedural pain and distress in children and adolescents. SEARCH METHODS: We searched six electronic databases for relevant trials: Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; PsycINFO; Embase; Web of Science (ISI Web of Knowledge); and Cumulative Index to Nursing and Allied Health Literature (CINAHL). We sent requests for additional studies to pediatric pain and child health electronic listservs. We also searched registries for relevant completed trials: clinicaltrials.gov; and World Health Organization International Clinical Trials Registry Platform (www.who.int.trialsearch). We conducted searches up to September 2017 to identify records published since the last review update in 2013. SELECTION CRITERIA: We included peer-reviewed published randomized controlled trials (RCTs) with at least five participants per study arm, comparing a psychological intervention with a control or comparison group. Trials involved children aged two to 19 years undergoing any needle related medical procedure. DATA COLLECTION AND ANALYSIS: Two review authors extracted data and assessed risks of bias using the Cochrane 'Risk of bias' tool. We examined pain and distress assessed by child self-report, observer global report, and behavioral measurement (primary outcomes). We also examined any reported physiological outcomes and adverse events (secondary outcomes). We used meta-analysis to assess the efficacy of identified psychological interventions relative to a comparator (i.e. no treatment, other active treatment, treatment as usual, or waitlist) for each outcome separately. We used Review Manager 5 software to compute standardized mean differences (SMDs) with 95% confidence intervals (CIs), and GRADE to assess the quality of the evidence. MAIN RESULTS: We included 59 trials (20 new for this update) with 5550 participants. Needle procedures primarily included venipuncture, intravenous insertion, and vaccine injections. Studies included children aged two to 19 years, with few trials focused on adolescents. The most common psychological interventions were distraction (n = 32), combined cognitive behavioral therapy (CBT; n = 18), and hypnosis (n = 8). Preparation/information (n = 4), breathing (n = 4), suggestion (n = 3), and memory alteration (n = 1) were also included. Control groups were often 'standard care', which varied across studies. Across all studies, 'Risk of bias' scores indicated several domains at high or unclear risk, most notably allocation concealment, blinding of participants and outcome assessment, and selective reporting. We downgraded the quality of evidence largely due to serious study limitations, inconsistency, and imprecision.Very low- to low-quality evidence supported the efficacy of distraction for self-reported pain (n = 30, 2802 participants; SMD -0.56, 95% CI -0.78 to -0.33) and distress (n = 4, 426 participants; SMD -0.82, 95% CI -1.45 to -0.18), observer-reported pain (n = 11, 1512 participants; SMD -0.62, 95% CI -1.00 to -0.23) and distress (n = 5, 1067 participants; SMD -0.72, 95% CI -1.41 to -0.03), and behavioral distress (n = 7, 500 participants; SMD -0.44, 95% CI -0.84 to -0.04). Distraction was not efficacious for behavioral pain (n = 4, 309 participants; SMD -0.33, 95% CI -0.69 to 0.03). Very low-quality evidence indicated hypnosis was efficacious for reducing self-reported pain (n = 5, 176 participants; SMD -1.40, 95% CI -2.32 to 0.48) and distress (n = 5, 176 participants; SMD -2.53, 95% CI -3.93 to -1.12), and behavioral distress (n = 6, 193 participants; SMD -1.15, 95% CI -1.76 to 0.53), but not behavioral pain (n = 2, 69 participants; SMD -0.38, 95% CI -1.57 to 0.81). No studies assessed hypnosis for observer-reported pain and only one study assessed observer-reported distress. Very low- to low-quality evidence supported the efficacy of combined CBT for observer-reported pain (n = 4, 385 participants; SMD -0.52, 95% CI -0.73 to -0.30) and behavioral distress (n = 11, 1105 participants; SMD -0.40, 95% CI -0.67 to -0.14), but not self-reported pain (n = 14, 1359 participants; SMD -0.27, 95% CI -0.58 to 0.03), self-reported distress (n = 6, 234 participants; SMD -0.26, 95% CI -0.56 to 0.04), observer reported distress (n = 6, 765 participants; SMD 0.08, 95% CI -0.34 to 0.50), or behavioral pain (n = 2, 95 participants; SMD -0.65, 95% CI -2.36 to 1.06). Very low-quality evidence showed efficacy of breathing interventions for self-reported pain (n = 4, 298 participants; SMD -1.04, 95% CI -1.86 to -0.22), but there were too few studies for meta-analysis of other outcomes. Very low-quality evidence revealed no effect for preparation/information (n = 4, 313 participants) or suggestion (n = 3, 218 participants) for any pain or distress outcome. Given only a single trial, we could draw no conclusions about memory alteration. Adverse events of respiratory difficulties were only reported in one breathing intervention. AUTHORS' CONCLUSIONS: We identified evidence supporting the efficacy of distraction, hypnosis, combined CBT, and breathing interventions for reducing children's needle-related pain or distress, or both. Support for the efficacy of combined CBT and breathing interventions is new from our last review update due to the availability of new evidence. The quality of trials and overall evidence remains low to very low, underscoring the need for improved methodological rigor and trial reporting. Despite low-quality evidence, the potential benefits of reduced pain or distress or both support the evidence in favor of using these interventions in clinical practice. PMID- 30284241 TI - A pilot study of cardiopulmonary exercise testing and cardiac stress positron emission tomography before major non-cardiac surgery. AB - Cardiac events are a common cause of peri-operative morbidity. Cardiopulmonary exercise testing can objectively assess risk, but it does not quantify myocardial ischaemia. With appropriate dietary preparation to suppress basal myocardial glucose uptake, positron emission tomography with 18 F-fluorodeoxyglucose can identify post-ischaemic myocardium, providing an attractive complement to exercise testing. We aimed to investigate the feasibility of this diagnostic algorithm. Patients referred for cardiopulmonary exercise testing before major cancer surgery were prospectively recruited. Exercise testing and positron emission tomography imaging were performed after a high fat-low carbohydrate meal. Protocol feasibility (primary end-point) included compliance with pre-test diet instructions and the completion of tests. Stress myocardial perfusion imaging was performed if either exercise testing or positron emission tomography was equivocal or positive for ischaemia. We recorded cardiac complications for 30 postoperative days. We enrolled 26 participants, 20 of whom completed protocol. Twenty-one participants proceeded to surgery: myocardial injury or infarction was diagnosed in three participants, two of whom had positive or equivocal positron emission tomography but negative myocardial perfusion imaging. We have shown that pre-operative cardiac positron emission tomography after cardiopulmonary exercise testing is feasible; protocol deviations were minor and did not affect image quality. Our findings warrant further investigation to compare the diagnostic utility of cardiac positron emission tomography imaging with standard pre operative stress tests.

Zuellig and Sweigart (2018a) find that alleles from a two-locus hybrid incompatibility system segregate at considerable frequencies in two species of monkeyflowers, suggesting that despite providing a fitness cost, these alleles remain polymorphic as a consequence of gene flow between the two species. The system provides the potential to understand the evolutionary trajectory of hybrid incompatibilities and their role in speciation. PMID- 30284243 TI - Regulatory aspects of status epilepticus.

PMID- 30284245 TI - Preserving the thyroidal isthmus during low tracheostomy with creation of a Bjork flap. AB - OBJECTIVES/HYPOTHESIS: Surgical tracheostomy (ST) with creation of an inferiorly based U-shaped tracheal flap, known as the Bjork flap, is the most commonly performed. The purpose of this study was to evaluate whether outcome was different in patients who underwent low ST with retraction and preservation of the thyroid isthmus compared to those who underwent high ST with ligation of the thyroid isthmus. STUDY DESIGN: Retrospective cohort study. METHODS: We included 1,143 patients who underwent ST with creation of a Bjork flap between 2008 and 2015. Different outcome parameters, including complications, decannulation, inpatient mortality, and surgical characteristics, such as length of surgery and height of tracheal incision, were assessed comparing low and high ST. RESULTS: Complications occurred in 7.7% of patients, of which persistent stoma (4.1%) and hemorrhages (2.7%) were the most common. Low tracheostomy with retraction and preservation of thyroid isthmus was done in 31.4% of cases. Complications did not significantly differ between low and high tracheostomies (8.0% vs. 7.0%, P = .468). Moreover, decannulation rate and inpatient mortality were also not significantly different in low compared to high tracheostomies (P = .816 and P = .152, respectively). However, low tracheostomies were associated with significantly shorter operation times (33.0 +/- 0.8 min vs. 38.7 +/- 0.5 min, P < .001) and lower tracheal incisions for creation of a Bjork flap (P < .001) compared to high tracheostomies. CONCLUSIONS: Low tracheostomies are as safe as high tracheostomies regarding complications. Due to the fact that low tracheostomies are associated with shorter operation times and lower tracheal incisions, we recommend performong low tracheostomies whenever feasible.

AB - OBJECTIVES/HYPOTHESIS: To reverse sarcopenia and increase the volumes of atrophied laryngeal muscles by functional electrical stimulation (FES) using a minimal invasive surgical procedure in an aged ovine model. STUDY DESIGN: Prospective animal study. METHODS: A stimulation electrode was placed unilaterally near the terminal adduction branch of the recurrent laryngeal nerve (RLN) adjacent to the right cricothyroid joint. The electrode was connected to an implant located subcutaneously at the neck region. Predesigned training patterns were automatically delivered by a bidirectional radio frequency link using a programming device and were repeated automatically by the implant every other day over 11 weeks in the awake animal. Outcome parameters comprised volumetric measurements based on three-dimensional reconstructions of the entire thyroarytenoid muscle (TAM), as well as gene expression analyses. RESULTS: We found significant increases of the volumes of the stimulated TAM of 11% and the TAM diameter at the midmembranous parts of the vocal folds of nearly 40%. Based on gene expression, we did not detect a shift of muscle fiber composition. CONCLUSIONS: FES of the terminal branches of the RLN is a secure and effective way to reverse the effects of age-related TAM atrophy and to increase volumes of atrophied muscles.

AB - OBJECTIVES/HYPOTHESIS: Evaluate bone resorption in free fibular grafts and document resorption behavior as compared to dentulous and edentulous autochthonous mandibular bone. STUDY DESIGN: Retrospective Chart review. METHODS: Postoperative computed tomography images were used to evaluate fibular graft resorption rates and corresponding sites of the dentulous or edentulous mandible. Bone height, width, and cortical thickness were measured. RESULTS: Eighteen patients underwent fibula free flap reconstruction following resection of a primary head and neck cancer. Mandibular defects were classified using Jewer's classification. The average interval loss of osseous height was 0.23 +/- 0.09 mm/yr for fibula flap, 0.55 +/- 0.13 mm/yr for dentulous native mandible, and 0.98 +/- 0.41 mm/yr in edentulous native mandible. Change in osseous width was 0.19 +/- 0.08 mm/yr, 0.55 +/- 0.33 mm/yr, and 0.73 +/- 0.15 mm/yr, respectively. Rate of superior cortical resorption was 0.33 +/- 0.34 mm/yr, 0.35 +/- 0.13 mm/yr, and 0.53 +/- 0.11 mm/yr in fibula flap, dentulous, and edentulous mandible, respectively. Inferior cortical resorption rates were quantified as 0.30 +/- 0.11 mm/yr, 0.35 +/- 0.08 mm/yr, and 0.51 +/- 0.08 mm/yr. CONCLUSIONS: Fibula free flap reconstruction of the mandible provides excellent functional results and allows for stable outcomes. Bone resorption is significantly lower in fibular graft compared with both edentulous and dentulous mandible. Edentulous bone displays significantly increased rates of atrophy in comparison to the dentulous mandible. This may have implications with regard to long-term viability of both the fibular flap and native mandible. The role of dental restoration on overall osseous stability warrants further research.

AB - OBJECTIVES: Sentinel lymph node biopsy (SLNB) has been shown to be an accurate technique for staging the neck in early-stage oral cavity squamous cell carcinoma (OCSCC) and has been incorporated in treatment guidelines as an option instead of elective neck dissection (END). However, utilization of SLNB in the United States remains unclear, and existing prospective studies did not directly compare survival between SLNB and END. METHODS: We conducted a retrospective cohort study of patients with stage I to II OCSCC (cT1-2cN0cM0) who underwent staging of the neck in the National Cancer Data Base from 2012 to 2015. We compared the practice patterns and outcomes of patients who underwent SLNB versus END. RESULTS: We identified 8,328 eligible patients with a median follow-up of 35.4 months. SLNB was used for 240 patients, or 2.9% of stage I to II OCSCC. Completion neck dissection was avoided in 63.8% of patients undergoing SLNB. SLNB was associated with reduced perioperative morbidity, with median length of hospital stay of 1.0 days versus 3.0 days after END (P < 0.001). Perioperative 30-day mortality was 0% after SLNB versus 0.7% after END (P = 0.42). Overall 3-year survival was 82.0% after SLNB and 77.5% after END (P = 0.40). After adjustment, overall survival was equivalent between patients who underwent SLNB versus END (adjusted hazard ratio 1.03, confidence interval 0.67-1.59). CONCLUSIONS: SLNB for stage I to II OCSCC is associated with reduced length of hospital stay and equivalent overall survival compared with END. Despite these attributes, SLNB remains rarely used in the United States. LEVEL OF EVIDENCE: NA. Laryngoscope, 2018. PMID- 30284249 TI - Elevation of extracellular osmolarity improves signs of myotonia congenita in vitro: a preclinical animal study. AB - KEY POINTS: During myotonia congenita, reduced chloride (Cl- ) conductance results in impaired muscle relaxation and increased muscle stiffness after forceful voluntary contraction. Repetitive contraction of myotonic muscle decreases or even abolishes myotonic muscle stiffness, a phenomenon called 'warm up'. Pharmacological inhibition of low Cl- channels by anthracene-9-carboxylic acid in muscle from mice and ADR ('arrested development of righting response') muscle from mice showed a relaxation deficit under physiological conditions compared to wild-type muscle. At increased osmolarity up to 400 mosmol L-1 , the relaxation deficit of myotonic muscle almost reached that of control muscle. These effects were mediated by the cation and anion cotransporter, NKCC1, and anti-myotonic effects of hypertonicity were at least partly antagonized by the application of bumetanide. ABSTRACT: Low chloride-conductance myotonia is caused by mutations in the skeletal muscle chloride (Cl- ) channel gene type 1 (CLCN1). Reduced Cl- conductance of the mutated channels results in impaired muscle relaxation and increased muscle stiffness after forceful voluntary contraction. Exercise decreases muscle stiffness, a phenomena called 'warm up'. To gain further insight into the patho-mechanism of impaired muscle stiffness and the warm-up phenomenon, we characterized the effects of increased osmolarity on myotonic function. Functional force and membrane potential measurements were performed on muscle specimens of ADR ('arrested development of righting response') mice (an animal model for low gCl- conductance myotonia) and pharmacologically-induced myotonia. Specimens were exposed to solutions of increasing osmolarity at the same time as force and membrane potentials were monitored. In the second set of experiments, ADR muscle and pharmacologically induced myotonic muscle were exposed to an antagonist of NKCC1. Upon osmotic stress, ADR muscle was depolarized to a lesser extent than control wild-type muscle. High osmolarity diminished myotonia and facilitated the warm-up phenomenon as depicted by a faster muscle relaxation time (T90/10 ). Osmotic stress primarily resulted in the activation of the NKCC1. The inhibition of NKCC1 with bumetanide prevented the depolarization and reversed the anti-myotonic effect of high osmolarity. Increased osmolarity decreased signs of myotonia and facilitated the warm-up phenomenon in different in vitro models of myotonia. Activation of NKCC1 activity promotes warm-up and reduces the number of contractions required to achieve normal relaxation kinetics. PMID- 30284250 TI - Tinnitus and taste disturbances reported after myringoplasty: Data from a national quality registry. AB - OBJECTIVES/HYPOTHESIS: Postoperative tinnitus and taste disturbances after myringoplasty are more common than previously reported. STUDY DESIGN: This study was a retrospective analysis of prospectively collected data from the Swedish National Quality Registry for Myringoplasty. METHODS: The analysis was performed on extracted data from all counties in Sweden collected from database A from 2002 to 2012 and database B from 2013 to 2016. Tinnitus and taste disturbance complications 1 year after myringoplasty were analyzed in relation to gender, age, procedure, and success rate. In database A, physicians reported tinnitus and taste disturbances. In database B, patients reported the complications. RESULTS: A major difference was found when the complications were reported by physicians compared to when the complications were reported by patients. In database A, tinnitus was reported in 1.2% of the patients and taste disturbances in 0.5%. In database B, the frequencies were 12.3% and 11.2%, respectively. Tinnitus and taste disturbances were more frequent after conventional myringoplasty compared to those after fat grafting and were more frequent after primary compared to those after revision surgery when reported by physicians. Patients, however, reported the same frequency of tinnitus after fat graft myringoplasty compared to that after conventional myringoplasty (12.0% vs. 12.6%) and fewer taste disturbances after revision surgery. In follow-up assessments, complications persisted after surgery over a long time period. CONCLUSION: Tinnitus and taste disturbances are more common after myringoplasty when patients report their symptoms than when physicians report the symptoms. LEVEL OF EVIDENCE: 2b.

AB - BACKGROUND: Vocal fold movement impairment (VFMI) secondary to neuronal injury is a known risk after aortic surgery. Total arch replacement is technically challenging, and the incidence of vocal fold movement impairment secondary to neuronal injury after this surgery is unknown. This study examined the incidence of VFMI after total arch replacement and medialization treatment outcomes. STUDY DESIGN: Retrospective cohort study. METHODS: All patients who underwent total arch replacement at a tertiary care center over 11 years (2006-2017) were identified through an institutional database. End points included evidence of VFMI on flexible laryngoscopy, time to diagnosis, time to treatment, need for reintubation, and intensive care unit (ICU) and hospital length of stay. RESULTS: Of the 358 patients who underwent total arch replacement, 63 (20%) were diagnosed with VFMI during their initial inpatient stay. Fifty patients (79%) VFMIs were left-sided, nine (14%) were right-sided, and four (6%) were bilateral. Thirty nine patients (62%) underwent inpatient vocal fold medialization: 28 (72%) by injection laryngoplasty and 11 (28%) by type 1 thyroplasty. Those with unilateral VFMI had longer ICU (8.9 days) and hospital (19.4 days) than those with no VFMI (5.7 and 16.1 days). Among patients with unilateral VFMI, those who underwent inpatient vocal fold medialization trended toward shorter ICU (6.2 vs. 14.4 days, P = .03) and hospital stays (20.1 vs. 23.3 days, P = .4) than patients who did not have a medialization procedure. CONCLUSION: The overall incidence of VFMI after total arch replacement in our series was 20%. Both the right and left vocal folds are potentially at risk from a total arch replacement; consequently, the distribution of injury in our cohort was more heterogeneous than in other series.

AB - OBJECTIVES/HYPOTHESIS: The aim of this study was to investigate changes in the cochlea and the potential dose-dependent effects of resveratrol (RSV) against diabetes mellitus (DM) ototoxicity. STUDY DESIGN: Animal model. METHODS: Twenty four male Wistar albino rats were divided into four groups. Baseline distortion product otoacoustic emission (DPOAE) measurements were evaluated. Group I was the control group, group II was made diabetic with single-dose streptozotocin, and groups III and IV were rendered diabetic as group II and administered 10 and 20 mg RSV, respectively, intraperitoneally for 4 weeks. All animals were sacrificed after repeated DPOAE measurement. Apoptosis was investigated using caspase-3, Bax (Bcl-associated X protein), and TUNEL (terminal deoxynucleotidyl transferase dUTP nick end labeling) staining. RESULTS: The DPOAE values in the diabetic group were found to be significantly lower compared with the other groups at 5,714 Hz and 8,000 Hz (P < .05). No significant difference in otoacoustic emission was detected in the comparison of the RSV doses (P > .05). The histopathologic investigation using caspase-3, Bax, and TUNEL staining showed that the mean rank of the diabetic group was significantly higher compared with the RSV10, RSV20, and control groups (DM > RSV10 > RSV20 > control) (P < .05). CONCLUSIONS: These results imply that RSV administration offered statistically significant protection for the cochleas of rats against diabetes. This protective effect improved histologically with higher doses. LEVEL OF EVIDENCE: NA Laryngoscope, 2018. PMID- 30284253 TI - Safety and feasibility of a novel recurrent laryngeal nerve monitoring technique. AB - OBJECTIVES/HYPOTHESIS: Continuous intraoperative nerve monitoring (CIONM) during thyroidectomy is promising technology that may reduce the incidence of recurrent laryngeal nerve (RLN) injuries. However, the current technique for CIONM, in which a stimulating probe is placed on the vagus nerve, has not been widely adopted because of concerns regarding its invasiveness and safety. A new method with the lead positioned on the RLN may overcome these objections and promote greater adoption of CIONM. This study was conducted to serve as the first step in determining the safety and feasibility of an RLN-based CIONM approach. STUDY DESIGN: Case series with planned data collection. METHODS: Fifty patients scheduled to undergo thyroidectomy were enrolled. In all cases, after identification of the RLN, a lead designed for CIONM was placed on the nerve. The lead was then left in place for a minimum of 2 minutes, and CIONM data were recorded. Laryngeal electromyographic (EMG) characteristics were assessed just before the lead was placed on the RLN and after it was removed. Pre- and postoperative fiberoptic laryngoscopy was performed to assess vocal cord function in all patients. RESULTS: In 49 patients (98%), the probe was successfully positioned on the RLN, and CIONM data were generated. On average, 1.4 attempts per patient were required to properly place the lead. No accidental dislodgements of the lead occurred during the experiments. No patients demonstrated significant EMG changes from baseline after manipulation and stimulation of the RLN. The average CIONM time was 175.7 s (range, 138-212 s), and the average CIONM amplitude and latency were 675.2 uV (range, 211.0-1405.2 uV) and 1.8 ms (1.25 1.9), respectively. All patients had normal bilateral vocal cord function preoperatively and at the first postoperative visit. CONCLUSIONS: This study demonstrates the apparent safety and viability of a CIONM technique using a lead placed directly on the RLN. Future investigations are warranted of this promising method, which may promote more widespread adoption of CIONM during thyroidectomy to reduce RLN injuries. LEVEL OF EVIDENCE: 4 Laryngoscope, 2018. PMID- 30284254 TI - Impact of Age on Sinus Surgery Outcomes. AB - OBJECTIVES/HYPOTHESIS: To evaluate the impact of age on patient-reported quality of life (QOL) following endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS). STUDY DESIGN: Prospective cohort study. METHODS: Six hundred thirty-six patients with CRS were recruited from 11 otolaryngologic practices and completed the sinonasal-specific, 22-item Sino-Nasal Outcome Test-22 (SNOT-22) and general health-related EuroQol 5-Dimension (EQ-5D) questionnaires at baseline and 12 and 24 months after ESS. Patients were grouped chronologically to determine whether age at time of ESS was associated with clinical outcomes. RESULTS: Ages ranged from 18 to 80 years (mean +/- standard deviation = 48.5 +/- 14.4). Improvement was observed in postoperative SNOT-22 scores at 12 and 24 months for all decades of life. Similar improvements were observed for EQ-5D-based health utility value (HUV) scores in all decades of life, except for the eldest cohort (ages 70-80, N = 33), who did not exceed the minimal clinically important difference at either 12 or 24 months following ESS. In regression analysis, age was not associated with sinonasal-specific outcomes (change in SNOT-22 scores) at 12 (P = .507) or 24 months (P = .955). In general health-related outcomes, however, age was significantly associated with change in EQ-5D-based HUV scores from baseline to 12 months following ESS after adjusting for patient demographics, comorbidities, and surgical history (P = .049). CONCLUSIONS: This study demonstrates that ESS for adult CRS sufferers offers improved QOL outcomes through the eighth decade of life. The impact of comorbidities on QOL needs to be carefully considered when assessing older patients for sinus surgery. LEVEL OF EVIDENCE: 2b Laryngoscope, 2018. PMID- 30284255 TI - Risk factors for thyroid surgery-related unilateral vocal fold paralysis. AB - OBJECTIVES/HYPOTHESIS: We aimed to identify the risk factors for iatrogenic unilateral vocal fold paralysis (UVFP) caused by thyroid surgery, to allow the identification of patients requiring nerve-protection procedures and monitoring technologies. STUDY DESIGN: Retrospective case study in a medical center. METHODS: Patients who underwent thyroid surgery from April 2011 to February 2016 and who were diagnosed with UVFP by laryngoscopy and laryngeal electromyography were included. Patient demographics, types of surgery, and characteristics of the thyroid lesions were analyzed. RESULTS: Sixty (2.1%) of 2,815 patients who received thyroid surgery developed UVFP. The risk of UVFP was higher in patients over 60 years old (odds ratio, 1.89; 95% confidence interval, 1.01-3.26; P = .01). Involvement of the external branch of superior laryngeal nerve (EBSLN) occurred in 19 (31.7%) of the 60 UVFP patients, and was more likely to occurr in patients with diabetes mellitus (odds ratio, 14.19; 95% confidence interval, 3.80 52.94; P < .001). The incidence of UVFP and involvement of the EBSLN differed among surgery types, and was the highest among patients undergoing total thyroidectomy with neck dissection (TTND) (10/158, 6.3% and 5/158, 3.2%, respectively). CONCLUSIONS: The risk of thyroid surgery-related UVFP is higher in older patients. EBSLN involvement is more likely in patients with diabetes mellitus. TTND is associated with higher risks of UVFP and EBSLN injury than other types of surgery, implying the need of intraoperative nerve monitoring in these high-risk characteristics. LEVEL OF EVIDENCE: 4 Laryngoscope, 2018. PMID- 30284256 TI - Percutaneous versus surgical tracheostomy: timing, outcomes, and charges. AB - OBJECTIVES/HYPOTHESIS: The purpose of this study was to compare timing of procedure, patient characteristics, outcomes, and charges for patients who underwent percutaneous versus surgical tracheostomy. STUDY DESIGN: Retrospective cohort study. METHODS: A retrospective analysis was performed for all patients who underwent tracheostomy in 2015 to 2016 in New York State. Patients were identified using International Classification of Diseases, 10th Revision, Clinical Modification codes and stratified to the type of tracheostomy performed. The primary outcome of interest was mortality at index stay. Secondary outcomes of interest included length of stay and total hospitalization charges. RESULTS: Of the 8,682 patients, 2,488 (28.7%) underwent percutaneous and 6,194 (71.3%) underwent surgical tracheostomy. At hospitals where both procedures were performed, percutaneous tracheostomy patients were older, had more comorbidities, and had lower income (P < .05). Timing of the tracheostomy relative to admission did not affect the type of tracheostomy performed. While controlling for patient characteristics and complications during the visit, percutaneous tracheostomy was associated with increased mortality (odds ratio [OR]: 1.17, 95% confidence interval [CI]: 1.03-1.33, P = .0153) and increased hospital charges (OR: + 7.76%, 95% CI: 5.4-10.11, P < .0001). Length of stay was not affected by procedure type. CONCLUSIONS: Surgical tracheostomies are more commonly performed than percutaneous tracheostomies across New York State. Older, lower-income, and sicker patients have a higher chance of receiving percutaneous tracheostomies. Percutaneous approaches were associated with statistically significant increased mortality and higher charges despite no difference in length of stay. Further studies are needed to determine if these differences in outcomes are clinically significant. LEVEL OF EVIDENCE: NA Laryngoscope, 2018. PMID- 30284257 TI - The Impact of Duty-Hour Restrictions on Complication Rates Following Major Head and Neck Procedures. AB - OBJECTIVES/HYPOTHESIS: To assess the impact of resident duty-hour restrictions (DHR) in otolaryngology via comparison of postoperative outcomes between otolaryngology teaching hospitals (Oto-TH) and nonteaching hospitals (NTH) before and after complete implementation. STUDY DESIGN: Retrospective database review. METHODS: The Nationwide Inpatient Sample was queried for all major head and neck cases between 2000 and 2002 (n = 34,064) and 2008 and 2010 (n = 33,094). Cases were stratified into Oto-TH (n = 28,771) and NTH (n = 38,387) and assessed for procedure type, patient comorbidities, and complications. A subpopulation matched by procedure type was generated for direct comparison of complication rates using chi2 and binary logistic regression analyses. RESULTS: In the years following DHR, total case volume and average case complexity increased at Oto-TH only. Using a case-matched subpopulation, regression analysis found Oto-TH status to be protective for medical complications both before (odds ratio [OR]: 0.60, P < .001) and after (OR: 0.76, P = .001) DHR. In contrast, Oto-TH cases had lower risk for surgical complications in 2000 to 2002 (OR: 0.77, P < .001) but not 2008 to 2010 (OR: 1.07, P = .275). When comparing time periods, the years following DHR were associated with a significant decrease in medical complications and mortality across hospital cohorts. For surgical complications, rates significantly improved at NTH only (OR: 0.82, P = .002), with no difference at Oto-TH (OR: 0.95, P = .450). CONCLUSIONS: In the years following DHR, rates of medical complications, surgical complications, and mortality have significantly improved at NTH. At Oto-TH, there has been a lack of similar improvement in surgical complications, even after accounting for increasing case volume and complexity in more recent years. While the cause is likely multifactorial, DHR in otolaryngology residency may play a role. LEVEL OF EVIDENCE: 4 Laryngoscope, 2018. PMID- 30284258 TI - Meta-Analysis of Obstruction Site Observed With Drug-Induced Sleep Endoscopy in Patients With Obstructive Sleep Apnea. AB - OBJECTIVE: To perform a meta-analysis on the distribution and characteristics of the obstructive site in patients with obstructive sleep apnea (OSA) using data from a variety of published studies that evaluated the obstruction with drug induced sleep endoscopy (DISE). METHODS: A literature search was performed to identify studies in which DISE was used to identify the obstruction site in adult patients with OSA, and the obstruction site was described in sufficient detail. Four items were evaluated in the meta-analysis: the obstruction site, closing direction of the soft palate, degree of closure, and percentage of single-level obstructions. RESULTS: A total of 2,950 patients from 19 studies were included. In the two-level classification system, the rate of obstruction was 91.6% for the soft palate and 58.0% for the tongue base. In the four-level classification system, the rate of obstruction was 84.1% for soft palate, 32.8% for the tonsil, 51.6% for the tongue base, and 34.3% for the epiglottis. The soft palate closed in the anteroposterior direction at a rate of 44.4% and in the concentric direction at a rate of 46.5%. The rate of a closure of 75% or more was 69.3% for the soft palate and 56.8% for the hypopharynx. The percentage of single-level obstructions was 42.5%. CONCLUSION: The soft palate is obstructed in most patients with OSA, and the tongue base is obstructed in half of the patients. In addition, multilevel obstructions including the tonsil, lateral pharyngeal wall, or epiglottis are common; thus, these areas must be checked carefully. LEVEL OF EVIDENCE: NA. Laryngoscope, 2018.

PMID- 30284261 TI - Intraoperative Margin Control in Transoral Approach for Oral and Oropharyngeal Cancer. AB - OBJECTIVES: Piecemeal resection provides an innovative conceptual tool for margins surveillance because it entails the intraoperative evaluation of the whole resection margins and not just sample points, which should result in a better control of deep margins compared to en bloc resection. Although it is recognized that the intraoperative use of narrow band imaging (NBI) results in a better control of superficial margins, in this exploratory study we investigated whether NBI and piecemeal resection could be used in combination to improve margin control at both superficial and deep levels. Because piecemeal resection is based on frozen section analysis, we wanted to verify its reliability compared to definitive histological examination. METHODS: The status of resection margins in a group of patients with oral and oropharyngeal cancers treated with NBI and laser CO2 piecemeal resection (group 1) was compared with that of an historical group of patients (group 2) treated with NBI and conventional en bloc resection. In group 1, sensitivity, specificity, and positive and negative predictive values were used to verify the rate of concordance between frozen section and definitive histology. RESULTS: The difference between deep positive margins in the two groups was statistically significant (P = 0.042). The high sensitivity and specificity (94.6% and 94.7%, respectively) of frozen section analysis also demonstrated its reliability in the examination of larger samples corresponding to the whole margin. CONCLUSION: Even if our findings are limited by the small number of patients, we are confident that the combined use of NBI and piecemeal resection could represent an attractive surgical strategy to improve margin control.

PMID- 30284263 TI - Hemolytic adverse effects of intravenous immunoglobulin: modeling predicts risk reduction with anti-A/B immunoaffinity chromatography and to a lesser extent with anti-A donor screening. AB - BACKGROUND: The risk of hemolytic events (HEs) with intravenous immunoglobulin (IVIG) therapy appears to be linked to isoagglutinins (anti-A and anti-B) in the product. Patient risk factors include high IVIG dose, blood group, and underlying inflammatory state. STUDY DESIGN AND METHODS: Using published anti-A and anti-B titers for IVIG products and HE rates calculated from HEs spontaneously reported to EudraVigilance, regression models were developed to infer the relationship between HE risk and IVIG isoagglutinin levels for each blood group. Applying estimated model coefficients to isoagglutinin levels associated with an IVIG (Privigen; CSL Behring, King of Prussia, PA), manufactured with and without isoagglutinin reduction steps, predicted HE risk values were generated for each product: 1) without any isoagglutinin reduction, 2) anti-A donor screening, and 3) anti-A/anti-B specific immunoaffinity chromatography (IAC; Ig IsoLo). RESULTS: Predicted HE risk was highest for blood group AB, followed by A and B; it was low for O. Projected population shares of HEs by blood group were similar to reported real-world data. Compared with the original process (no isoagglutinin reduction), the model predicts lower hemolytic risk with anti-A donor screening and even lower hemolytic risk with IAC isoagglutinin reduction. CONCLUSION: IAC isoagglutinin reduction is predicted to reduce the HE risk with IVIG substantially. Physicians should be especially vigilant to HE risk in patients with blood group AB and, to a lesser extent, A when using IVIG products with high anti-A titers. PMID- 30284264 TI - Transoral Thyroidectomy Using A Flexible Robotic System: A Preclinical Cadaver Feasibility Study. AB - OBJECTIVES/HYPOTHESIS: Traditionally, most thyroid surgery utilizes a curvilinear cervical incision with a resulting permanent scar. Minimally invasive and remote access thyroid surgery techniques continue to evolve. Transoral approaches through a vestibular incision have been developed at several centers throughout the world, obviating the need for a cutaneous incision and optimizing aesthetics. To date this technique has been performed using rigid endoscopes or a linear robotic platform. The goal of this study was to test the feasibility of a novel flexible robotic system to perform a transvestibular thyroidectomy in a preclinical cadaver model. STUDY DESIGN: Preclinical feasibility study. METHODS: Right and left thyroid lobectomies were successfully performed via a transvestibular approach in four cadavers. RESULTS: A single vestibular incision between bilateral mental nerves allowed entrance of the flexible robot in a subplatysmal plane in both male and female cadavers. The recurrent laryngeal nerves and parathyroids were identified and preserved. The flexible three dimensional camera allowed excellent visualization and could be easily repositioned for optimal visualization of right and left structures. The flexible and wristed instruments enabled an atraumatic approach and allowed for precise surgical technique. CONCLUSIONS: The transoral vestibular approach to the central neck is a promising technique for thyroidectomy with optimal cosmesis and can be successfully accomplished using this novel flexible robotic system. Improvements in visualization and access offered by this system may improve application of this technique. LEVEL OF EVIDENCE: NA Laryngoscope, 2018. PMID- 30284265 TI - Medical Versus Surgical Treatment of Pediatric Acute Mastoiditis: A Systematic Review. AB - OBJECTIVE: There is no standard of care for treatment of pediatric acute mastoiditis (PAM). We systematically reviewed the English literature to evaluate the efficacy of PAM treatment options. METHODS: PubMed, Embase, MEDLINE, Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Library were searched from inception to January 2016, along with manual bibliography searches, for studies describing surgical or medical therapy. Two independent evaluators reviewed each abstract and article. RESULTS: We identified 310 articles, and 55 met inclusion criteria. Thirty-three evaluated surgical options and included 2,930 patients (mean age = 2.8 years) including those with myringotomy +/- tube placement (n = 920); 140 needed additional surgery, drainage of subperisoteal abscess (SPA) (n = 142) +/- myringotomy or tube placement, 29 patients needed additional surgery and mastoidectomy +/- myringotomy or tube placement (n = 612), with 611 reporting resolution. Using a random effects model, the estimated success probability with 95% confidence intervals (CI) are myringotomy +/- tube placement 94% (95% CI: 84.5%-97.8%), and drainage of subperiosteal abscess with concurrent myringotomy +/- tube placement was 86.5% (95% CI: 66.4%-95.4%). Using a random effects model, mastoidectomy success was 99.7% (95% CI: 77.5%-100%). Nineteen studies evaluated medical therapy (n = 990 patients). The average cure rate was 71.7% (median = 70%; range, 26.3%-100%), and estimated success was 72.9% (95% CI: 60.5%-82.5%) by meta-analysis. CONCLUSIONS: Myringotomy with or without tube placement and mastoidectomy have the highest cure rates for PAM. With SPA, incision and drainage with myringotomy with or without tube can be considered.

PMID- 30284267 TI - Dexpramipexole depletes blood and tissue eosinophils in nasal polyps with no change in polyp size. AB - OBJECTIVE: Chronic rhinosinusitis with nasal polyps (CRSwNP) and eosinophilia is a disease of the upper respiratory tract for which few therapies are available. Because the oral investigational drug dexpramipexole serendipitously decreased blood eosinophils in amyotrophic lateral sclerosis studies, we assessed its safety, eosinophil-lowering activity, and preliminary clinical efficacy in patients with CRSwNP and eosinophilia. METHODS: Sixteen subjects with CRSwNP, absolute eosinophil count (AEC) >= 0.300 * 109 /L, and polyp tissue eosinophils were evaluable for efficacy in a 6-month open-label, multi-center study of dexpramipexole 150 mg twice daily. The coprimary endpoints were change in AEC and change in total polyp score (TPS) from baseline to month 6, with additional clinical and histologic endpoints assessed. RESULTS: Thirteen of 16 subjects completed 6 months of dexpramipexole treatment. Geometric mean baseline AEC was 0.525 +/- 0.465 eosinophils * 109 /L and decreased to 0.031 +/- 0.019 after 6 months of dexpramipexole treatment, a 94% reduction (P < 0.001). Ten of 16 subjects had eosinophil counts reduced to <= 0.020 * 109 /L at month 6. In 12 subjects with nasal polyp biopsies at baseline and month 6, tissue eosinophils were reduced from a mean of 168 +/- 134 to 5 +/- 2 per high-power field (HPF) (P = 0.001), a 97% reduction from baseline. There was no significant reduction in TPS or improvement in other clinical endpoints. Dexpramipexole was well tolerated, with no drug-related serious adverse events. CONCLUSION: Dexpramipexole treatment produced profound eosinophil-lowering in peripheral blood and nasal polyp tissue. Despite the near-elimination of polyp eosinophils, decreased TPS and nasal symptom improvement were not observed. LEVEL OF EVIDENCE: 2. Laryngoscope, 2018.

PMID- 30284269 TI - Clinical Implications of Intralesional Steroid Injections in the Management of Otohematoma. AB - OBJECTIVES/HYPOTHESIS: To evaluate the long-term effects of intralesional steroid injections (ILSIs) in patients with otohematoma and to suggest the clinical implications, especially with regard to the duration of otohematoma. STUDY DESIGN: Retrospective analysis. METHODS: Fifty-six patients were enrolled and classified into short-term otohematoma (n = 30) and long-term otohematoma (n = 26) groups according to the period of time after auricular trauma. After the first ILSI, all patients underwent weekly examinations during the 21-day observational period to determine the treatment outcomes and were then followed up for reevaluation for a maximum of 36 months. We considered ILSIs to be ineffective if the otohematoma persisted after the third ILSI, and we opted to perform surgical treatment in such cases. In addition, we evaluated early recurrence, late recurrence, and ILSI-related complications. RESULTS: After up to three ILSIs, 29 out of 30 cases (96.7%) with short-term otohematoma and 20 out of 26 cases (76.9%) with long-standing otohematoma were treated without complications. Three patients with long-term otohematoma, however, experienced late recurrences at 4, 15, and 18 months, respectively. Seven patients who showed no response after ILSIs underwent surgical treatment. The duration of otohematoma (P = .043) and a higher initial aspirated fluid volume (P = .014) were shown to significantly increase the risk of treatment failure after ILSIs. CONCLUSIONS: Multiple and immediate ILSIs in patients with otohematoma appear to be an effective treatment approach with no complications. Patients with short-term otohematoma showed better outcomes following ILSIs. The treatment approach may be optimized based on the duration and degree of otohematoma.

AB - OBJECTIVES/HYPOTHESIS: Given the costs of healthcare, capitation, and desires for quality improvement (QI), there is a need to better assess healthcare value. Time driven activity-based costing and the Quadruple Aim have evaluated value by assessing health outcomes and provider experiences relative to costs. The proposed OPPS/Cost method expands on this to examine value for aerodigestive clinic treatment of pediatric persistent pharyngeal dysphagia: O + P1 + P2 + S/Cost (O = objective health [video-fluoroscopic swallow study results], P1 = patient/family experience [Consumer Assessment of Healthcare Providers and Systems], P2 = provider experience [Copenhagen Burnout Inventory {CBI}], S = subjective health [Feeding/Swallowing-Impact Survey], C = cost [time-driven activity-based costing]). STUDY DESIGN: Use of QI time data, surveys, and retrospective chart review for 56 patient encounters. METHODS: Staff interviews were used to develop process maps, and monetary values were assigned to activities. OPPS/Cost outcomes were normalized amongst variables, and composite values were calculated. Comparisons were made using a Student t test for pre- and postclinic relocation over a 14-month period. RESULTS: Time reductions were check in (13 minutes/patient), rooming (21 minutes/patient), and providers (4 minutes/patient). Patient in-room wait time increased (4 minutes/patient). The CBI identified burnout as an area for improvement. OPPS/Cost composite values increased by 14%, with a 1.7% cost reduction, improvement in objective and subjective health outcomes of 47.4% (P < .05) and 7.3%, respectively, and stable patient/family experience. CONCLUSIONS: OPPS/Cost is feasible in an interdisciplinary clinic and helped evaluate value during a clinic relocation. The QI opportunities identified are indicative of the potential of OPPS/Cost.

AB - OBJECTIVES/HYPOTHESIS: Examine US and international clinical trials in obstructive sleep apnea (OSA) to characterize researchers involved, interventions being studied, and opportunities for future investigation. STUDY DESIGN: Retrospective database review. METHODS: The information from ClinicalTrials.gov was used to assess OSA clinical trials between 1999 and 2017. Information was gathered on principle investigator (PI) demographics, interventions studied, study funding source, and regional distribution of research institutions. RESULTS: There were 813 clinical trials studied. The majority of trials examined continuous positive airway pressure interventions (43.7%), with pharmacotherapies being the second most commonly investigated treatment (19.2%). Surgical interventions made up 10.7% (n = 87) of clinical trials for OSA. Most studies were based internationally (59.9%). PIs were predominantly male (72.0%); 72.7% had an MD and 28.6% had a PhD. There were no significant differences in funding source (National Institutes of Health vs. industry, P = .14) or institutional geography (international vs. US, P = .73) between surgical and nonsurgical studies. Surgical trials were significantly more likely to have a male PI and involve pediatric patients compared to nonsurgical trials (P < .001). Otolaryngologists represented 9.2% of all PIs and had similar rates of NIH funding compared to other medical specialists (P = .22). CONCLUSIONS: This study provides a broad overview of past, current, and future treatment paradigms for OSA. Sleep surgery, specifically otolaryngology, is a small voice in the overall landscape of clinical trials for OSA. This information can help guide future research efforts and direct our specialty when setting priorities regarding research funding while encouraging a broad and interdisciplinary pursuit.

AB - OBJECTIVES/HYPOTHESIS: Endoscopic sinus surgery (ESS) is frequently performed for recurrent acute rhinosinusitis (RARS). Appropriate indications for surgery among patients with RARS have not yet been rigorously determined. The objective of this study was to define appropriateness criteria for ESS in the management of adult RARS. STUDY DESIGN: Application of RAND-UCLA appropriateness methodology. METHODS: A panel of nine multidisciplinary experts in RARS was formed to evaluate RARS scenarios generated from current evidence. The panel completed two rounds of a modified Delphi-ranking process and a teleconference. RESULTS: A total of 32 clinical scenarios were ranked in each round. For adult patients with RARS, ESS can appropriately be offered as a treatment option when patients experience >= four annual episodes, and there is confirmation of at least one episode via computed tomography or nasal endoscopy, and the patient and clinician jointly participate in shared decision making, and the patient has either failed a trial of topical nasal steroids or experienced RARS-related productivity loss. CONCLUSIONS: This study has defined appropriateness criteria for ESS as a management option for adult patients with RARS. These criteria are intended to represent a minimum threshold for which ESS should be considered in the treatment of RARS and do not suggest that all patients who meet these criteria should undergo surgery. These criteria may serve as a baseline set of indications for ESS in patients with RARS. LEVEL OF EVIDENCE: NA. Laryngoscope, 2018. PMID- 30284273 TI - Long-Term Outcome of Hearing Rehabilitation With An Active Middle Ear Implant. AB - OBJECTIVE: To assess the audiological and long-term medical and technical follow up outcomes of an active middle ear implant. METHODS: This was a retrospective medical chart analysis of all patients provided with an active middle ear implant in a tertiary academic medical referral center between September 1, 1998, and July 31, 2015. Main outcome measures were medical and technical complications, revisions, reimplantations, explantations, coupling approaches, mean time of use, pre- and postoperative hearing thresholds, functional hearing gain across frequencies (250-4,000 Hz), and Freiburg monosyllablic word test at 65 dB. RESULTS: One hundred and three patients were identified. Fifteen were implanted bilaterally (n = 118 Vibrant Soundbridge devices [MED-EL, Innsbruck, Austria]). Seventy-seven devices were implanted for sensorineural and 41 for mixed and conductive hearing loss. Patients used the implant for 6.7 years (range 0.7 months-17.9 years) on average. Ninety-one patients (77.12%) were using the device at the end of the observation period. An overall complication rate of 16.1% was observed. The revision and explantation rates were higher for devices implanted between 2004 and 2006. The device failure rate was 3.4%. Audiological evaluation showed significant hearing gains for both hearing loss patient groups. CONCLUSION: This long-term follow-up reveals the reliability of the active middle ear implant in a single center. Overall complication rate and device failure rate are acceptable. The complication rate was higher during implementation of alternative coupling approaches. The audiological benefit was satisfactory in patients with all hearing loss types. The majority of implanted patients used the implant at the end of the observation period. LEVEL OF EVIDENCE: 4. Laryngoscope, 2018. PMID- 30284275 TI - How I reduce the risk of missed irradiation transfusion events in children. PMID- 30284274 TI - Computerized Tomography Analysis of Young Children for Prevention of Aspiration Injuries. AB - OBJECTIVE: The Small Parts Test Fixture (SPTF) (16 CFR 1501) was developed from cadavers of young children and foreign body (FB) data. Recent FB studies reveal that the SPTF misses outliers. Computerized tomography (CT) provides detailed dimensional data for young children. Our null hypothesis is that the SPTF (31.75 mm) is smaller than relevant portions of the aerodigestive tract. METHODS: A 3 year retrospective review (2011-2014) of head/neck CT data for infants and children (N = 106) aged 6 months to 6 years was completed. Six measurements (mm) were recorded: 1) maxillary incisors to posterior edge of hard palate (MI/HP); 2) posterior edge of hard palate to first cervical (C1) vertebra (HP/C1); 3) soft palate to posterior pharyngeal wall; and 4) interpalatine tonsillar distance; 5, 6) larynx diameter, and width. Two ratios were calculated: 1) ratio of lengths (hard palate to soft palate), and 2) laryngeal dimensional ratio. RESULTS: A linear trend of increasing dimensions with increased age was noted. The length measured MI/HP best correlates with known data of potential FBs causing injury or death. This MI/HP length can range from 33.8 to 45.8 mm for all children younger than 3 years of age and exceeds the SPTF diameter (31.75 mm). There were no statistical anatomical differences by gender in any of the age groups. CONCLUSION: Computed tomography measurements appear larger than SPTF values developed from cadavers. These CT data support enlargement of the SPTF to enhance safety for choking hazards in children. LEVEL OF EVIDENCE: 4. Laryngoscope, 2018. PMID- 30284277 TI - Clinical Characteristics of Bilateral Meniere's Disease in a Single Asian Ethnic Group. AB - OBJECTIVES/HYPOTHESIS: To identify the clinical characteristics of patients with bilateral Meniere's disease (MD) in an Asian population. STUDY DESIGN: Cross sectional retrospective study. METHODS: We compared the clinical features of bilateral MD (BMD) and unilateral MD (UMD) in 320 Asian patients with single ethnicity. Demographic variables; age of onset; inner ear function; the coexistence of related disorders such as vestibular migraine, delayed MD, systemic autoimmune diseases, and familial MD; and prognoses were analyzed and compared. RESULTS: The overall prevalence of BMD was 5.6%. The mean age of disease onset was 40.3 +/- 14.8 and 47.0 +/- 14.1 years for patients with BMD and UMD, respectively (P = .07). Demographic variables were not significantly different between patients with BMD and UMD (P > .05). Inner ear function, evaluated by hearing thresholds, caloric tests, and cervical vestibular evoked myogenic potentials, was significantly more deteriorated in the first involved ear of patients with BMD than in the second involved ear or the affected side of patients with UMD (P < .05). Among the comorbid conditions, only the prevalence of delayed MD was significantly higher in patients with BMD than in patients with UMD. Systemic autoimmune disease was found in only three patients with UMD. There was no significant prognostic difference between patients with UMD and BMD (P > .05). CONCLUSIONS: A low prevalence of BMD, a higher frequency of delayed MD in BMD patients, and a low frequency of systemic autoimmune diseases in both UMD and BMD patients are significant findings in an Asian population. LEVEL OF EVIDENCE: 4 Laryngoscope, 2018. PMID- 30284276 TI - Intratympanic Therapies in Meniere Disease: Evaluation of Outcomes and Early Vertigo Control. AB - OBJECTIVE: To evaluate outcomes of intratympanic (IT) dexamethasone and gentamicin in Meniere Disease (MD). METHODS: Charts of adult patients with unilateral definite MD receiving IT gentamicin or dexamethasone from 2005 to 2017 were retrospectively reviewed. All patients had at least 6 months follow-up. Failure in each group was defined as the need for more aggressive therapy. Prior to 2011, all patient received IT gentamicin, administered as primary therapy after failure of conservative treatment measures. Gentamicin was administered every 2 weeks, up to three injections, until vertigo control was achieved. Beginning in 2011, the treatment protocol shifted to IT dexamethasone as initial treatment, with gentamicin used for dexamethasone failures. Dexamethasone was administered weekly for up to three injections. Treatments could be repeated if symptoms recurred. RESULTS: Thirty-three patients received IT dexamethasone, and 70 patients received IT gentamicin. Dexamethasone patients received a mean of 3.3 injections compared to 2.7 in the gentamicin group (P = 0.011). There were 12 (38%) failures in the dexamethasone group and only seven (10%) gentamicin failures (P = 0.025). No patients failed both treatments. The mean time to failure in the dexamethasone group was 5 months, whereas in the gentamicin group it was 27 months. Change in pure tone audiometry from baseline was not different between treatment groups (P = 0.30). CONCLUSION: Subjects receiving IT gentamicin required fewer injections and had a significantly longer time to failure than IT dexamethasone. Audiometric outcomes were similar between the groups. The use of IT gentamicin as initial therapy for early and long-term control of MD is safe and effective. LEVEL OF EVIDENCE: 3. Laryngoscope, 2018. PMID- 30284278 TI - Comparison of Modern Rigid Fixation Plating Outcomes for Segmental Mandibular Microvascular Reconstruction. AB - OBJECTIVES/HYPOTHESIS: New advances in osseous microvascular mandibular rigid fixation are being employed at many institutions. These include standardized prebent/preformed reconstruction plates as well as computer-aided design/computer aided manufacturing (CAD/CAM) custom plates that are patient specific. Our goal was to assess and compare the outcomes of both of these new technologies when utilized for mandibular microvascular reconstruction. STUDY DESIGN: Retrospective chart review. METHODS: Subjects were categorized into two groups according to their mandibular rigid fixation technique: group 1 = prebent/preformed plates and group 2 = CAD/CAM custom plates. Primary outcome measures were 1) perioperative complications (defined as deep tissue infection, wound dehiscence resulting in bone exposure, and/or plate exposure) and 2) reoperation rates for mandibular hardware failure/explantation. Statistical analysis consisted of chi2 , Fisher exact test, and multivariable regression models. RESULTS: A total of 142 subjects underwent microvascular mandibular reconstruction in a 6-year period. Eighty-nine subjects utilized prebent/preformed plates, and 53 employed CAD/CAM custom plates. Perioperative complications occurred in 32 of 89 (35.9%) subjects with prebent/preformed plates and 11 of 53 (20.7%) subjects using CAD/CAM custom plates. Reoperation requiring hardware explantation occurred in 18 of 89 (20.2%) subjects and three of 53 (5.6%) using CAD/CAM custom plates. Statistical comparison of perioperative complications between the two groups approached significance (P = .0556), and the rate of reoperation was significant favoring CAD/CAM implants (P = .0180). CONCLUSIONS: In our experience, CAD/CAM custom plates utilized for rigid fixation during microvascular mandibular reconstruction demonstrated fewer complications and statistically lower reoperation rates when compared with prebent/preformed plates.

AB - OBJECTIVES/HYPOTHESIS: To determine the relationship between mucosal-associated sinus and bronchial microbiota in cystic fibrosis (CF) patients compared to non CF patients with chronic rhinosinusitis (CRS). STUDY DESIGN: Case series. METHODS: We examined the microbial composition of 52 paired sinus and bronchial brushings from 26 patients with CRS. Paired airway samples from nine subjects with CF were compared with samples from 17 non-CF-CRS disease control patients. The Illumina MiSeq platform was used to sequence the V4 region of the 16S rRNA gene. Sequences were analyzed using QIIME 1.9.0. RESULTS: CF patients demonstrate increased severity of sinus inflammation (Lund-Mackay score 16.3 vs. 12.4, P = .023) and diminished diversity of microbial communities in both the sinuses (Shannon diversity 0.98 vs. 3.3, P = .009) and lungs (Shannon diversity 2.2 vs. 4.0, P = .042) relative to non-CF-CRS. Non-CF-CRS sinus and lung microbiota were distinct and clustered by niche (sinus vs. lung, P = .004). However, CF airway microbiota demonstrated a loss of niche specificity (sinus vs. lung, P = .492). Two CF patients underwent lung transplantation at 4.5 and 9 months prior to sampling. Sinus and lung samples from these two patients demonstrated distinct microbial communities. CONCLUSIONS: Patients with CF undergoing surgery for CRS exhibit substantial bacterial community collapse in the sinuses and a loss of niche specificity between the upper and lower airways compared to non-CF patients with CRS. These results extend previous studies elucidating the lower airway microbiome in cystic fibrosis and provide support for the concept of microbial translocation in the cystic fibrosis airways.

AB - BACKGROUND: Almost 20% of parvovirus B19 foetal infections require intrauterine transfusions. In addition, myocardial dysfunction has been observed in severe parvovirus B19 infections. One objective of an intrauterine exchange transfusion (IUET) is to avoid an overload during the transfusion. Our aim was to study the obstetrical and neonatal outcomes in cases of IUETs performed for foetal parvovirus infections and to compare our survival rate to those studies in which simple in utero transfusions were chosen. STUDY DESIGN AND METHODS: This was a retrospective monocentre study of all patients followed up for parvovirus B19 infections in which IUETs were performed. An IUET was indicated when foetal hydrops was observed and/or when severe foetal anaemia was diagnosed though an elevation in the middle cerebral artery peak systolic velocity. The characteristics of each pregnancy and the neonatal outcomes were studied until hospital discharge. RESULTS: Thirty-five IUETs were performed in 26 foetuses. The median gestational age of the first IUET was 22.6 weeks. Only one foetal bradycardia incidence was recorded during the procedure. Three medical pregnancy terminations were observed in our series, secondary to severe cerebral anomalies confirmed in the magnetic resonance imaging. Five in utero deaths occurred, in which 2 of the foetuses underwent multiple IUETs. All the neonates had normal haemoglobin levels at birth, and none were transferred to the neonatal intensive care unit. The overall survival rate was 70%. CONCLUSION: IUETs exhibit a survival rate similar to that of simple intrauterine transfusions in foetal parvovirus infection cases.

PMID- 30284282 TI - Floral uniformity through evolutionary time in a species-rich tree lineage. AB - Changes in floral morphology are expected across evolutionary time and are often promoted as important drivers in angiosperm diversification. Such a statement, however, is in contrast to empirical observations of species-rich lineages that show apparent conservative floral morphologies even under strong selective pressure to change from their environments. Here, we provide quantitative evidence for prolific speciation despite uniform floral morphology in a tropical species-rich tree lineage. We analyse floral disparity in the environmental and phylogenetic context of Myrcia (Myrtaceae), one of the most diverse and abundant tree genera in Neotropical biomes. Variation in floral morphology among Myrcia clades is exceptionally low, even among distantly related species. Discrete floral specialisations do occur, but these are few, present low phylogenetic signal, have no strong correlation with abiotic factors, and do not affect overall macroevolutionary dynamics in the lineage. Results show that floral form and function may be conserved over large evolutionary time scales even in environments full of opportunities for ecological interactions and niche specialisation. Species accumulation in diverse lineages with uniform flowers apparently does not result from shifts in pollination strategies, but from speciation mechanisms that involve other, nonfloral plant traits. PMID- 30284283 TI - Impact of Head and Neck Cancer Treatment on Survivors' Mealtime Experience. AB - OBJECTIVES/HYPOTHESIS: The objectives of the study were to develop a mealtime experience self-assessment questionnaire that was head and neck cancer (HNC) survivors-driven and based on the International Classification of Functioning, Disability and Health (ICF) framework, and to identify common mealtime issues reported by HNC survivors. STUDY DESIGN: Outcomes research. METHODS: Mealtime issues reported by HNC survivors in prior research was synthesized and classified using the ICF framework to develop the content and structure of the Head and Neck Cancer Survivors' Assessment of Mealtimes (HNSAM). A total of 122 HNC survivors completed both HNSAM and M.D. Anderson Dysphagia Inventory (MDADI) to assess for concurrent validity, whereas 51% of participants completed a second HNSAM for test-retest reliability. RESULTS: The HNSAM scores were significantly correlated with the MDADI scores. Dysphagic participants (n = 45) had significantly higher HNSAM scores than the nondysphagic participants (n = 77). Principal component analysis revealed three factors that matched with the HNSAM subscales. Good internal consistency (Cronbach's alpha = 0.72-0.96) and test-retest reliability (intraclass correlation = 0.76-0.91) were found. Both dysphagic and nondysphagic participants reported difficulties with saliva-related issues and were not able to enjoy food/drinks that they previously enjoyed. CONCLUSIONS: HNC survivors experience mealtime changes after cancer treatment. These initial validity data support the potential for the HNSAM to help HNC survivors' identify changes to the mealtime experience. Validation of the English version of the tool is now required.

AB - OBJECTIVE: To compare voice outcomes of autogenous fat injection versus medialization laryngoplasty in patients with glottic insufficiency due to vocal fold paresis or atrophy. METHODS: A retrospective review was performed from 2009 to 2017 of all patients who underwent lipoinjection or medialization laryngoplasty (ML) for glottic insufficiency. Charts were reviewed for demographic information, preoperative diagnosis, surgical intervention, Voice Handicap Index-10 (VHI-10) and Glottal Function Index (GFI) scores, follow-up time (minimum 3 months), and concomitant voice therapy. RESULTS: Eighty-three patients were initially identified and limited to 28 based on the inclusion/exclusion criteria. Thirty-five procedures were performed with a total of 15 fat injections and 20 MLs. The mean age was 60.7 years in the lipoinjection group and 55.6 years in the ML group. There was no significant difference in pretreatment VHI-10 scores between the two groups. Using the lowest recorded voice scores during the follow-up period, both groups had a significant decrease (P < 0.05) compared to preoperative scores (VHI-10: fat decreased from 27.8 to 14.2, ML decreased from 30.5 to 9.1; GFI: fat decreased from 13.7 to 5.27, ML decreased from 13.6 to 4.6). When evaluating the entire follow-up period (median 19 months in fat group, 16.3 months in ML), only the ML group maintained a significant improvement in VHI-10 (median delta 14.5) and GFI (median delta 7) compared to preoperative scores. CONCLUSION: Although both autogenous fat injection and ML result in improved voice scores in the short term, the effect of fat injection appears to be limited, as evidenced by worsening VHI-10 and GFI scores over time.

AB - BACKGROUND: Recently, there has been an increase in the number of hepatitis A outbreaks in the United States. Although the presence of hepatitis A virus (HAV) RNA in blood donors is known to be low, HAV antibody prevalence in this population is unknown. STUDY DESIGN AND METHODS: Samples from 5001 US blood donors collected primarily in the midwestern United States in 2015 were tested for the presence of HAV IgG antibodies using chemiluminescent microparticle immunoassays on the ARCHITECT platform (Abbott Laboratories). RESULTS: The overall prevalence of IgG anti-HAV was 60%. Only one specimen was IgM anti-HAV positive, for an incidence of 0.02%. IgG anti-HAV prevalence among donors aged 16 to 19 years was 67%, decreased to 54% among donors aged 40 to 49 years and increased to 70% among donors aged 80 to 93 years. No differences were seen by sex with overall IgG anti-HAV prevalence of 61% and 60% for males and females, respectively. Among the five states (Illinois, Indiana, Kansas, Kentucky, and Missouri) with the highest number of donors tested, IgG anti-HAV prevalence in Missouri (65%) was significantly higher (p <0.01) than that in Illinois (52%) or Kentucky (59%). No other significant differences between states were noted. CONCLUSION: This study demonstrates the overall high rates of IgG anti-HAV in US blood donors, with the low associated risk of HAV transfusion transmission likely the result of low incidence and effective vaccination. PMID- 30284287 TI - Four novel silenced RHCE. PMID- 30284288 TI - Long-term monitoring of virus antibody titers in human intravenous immunoglobulin lots derived from donors in Japan. AB - BACKGROUND: Intravenous immunoglobulin (IVIG) contains immunoglobulin G against various viruses, except those that have been screened, such as human immunodeficiency and hepatitis C viruses. Antivirus titers reflect the serostatus of the blood donor population in the collection region and are of clinical interest. STUDY DESIGN AND METHODS: During the past 10 years, measles, mumps, rubella, varicella-zoster, hepatitis A and B, Epstein-Barr, and human respiratory syncytial viruses; human parainfluenza viruses 1, 2, and 3; human herpes simplex viruses 1 and 2; human herpesvirus 6; cytomegalovirus (CMV); human adenoviruses (HAdVs) 1, 2, 3, 7, and 11; human parvovirus B19; and human echovirus 9 and 11 titers in IVIG lots have been measured by a commercial testing facility. A viral neutralizing assay for CMV has been used at our facility. Herein, we summarize the measurements and results of a regression analysis of the trends in virus antibody titers. RESULTS: IVIG lots contained significant titers against all of the above viruses, except for HAdV 7. Three patterns-stable, increasing, and decreasing-were observed, without any drastic changes. Although these trends reflect the seroprevalence in Japan, the titers were not obviously affected by the cycle of epidemics. On the other hand, the prevalence data suggest that titers against hepatitis A virus and other viruses will decrease in the near future, although they are currently stable. CONCLUSION: Monitoring the titer of IVIG lots and seroprevalence of donor populations is important for anticipating future changes in virus antibody titers of IVIG lots and can provide useful information of clinical interest. PMID- 30284289 TI - Alloimmunization risk associated with amino acid 223 substitution in the RhD protein: analysis in the light of molecular modeling. AB - BACKGROUND: Partial D status is a major concern for transfusion and pregnancy, due to the possibility of carriers becoming immunized. When known carriers of a D variant have never been exposed to complete D, they are assumed to have D partial status based on the position of the amino acid substituted. New approaches for predicting immunization risk are required. We built a three-dimensional (3D) structural model to investigate the consequences of substitutions of Amino Acid 223 involved in a large number of D variants. STUDY DESIGN AND METHODS: Homology modeling was performed with multiple templates. The model was evaluated by comparing the interactions of the known p.Phe223Val variant (RHD*08.01) and a new p.Phe223Ser variant (RHD*52) to RhD reference allele (p.Phe223). The consequences predicted by modeling the variants were compared with serologic data. RESULTS: The 3D structural model was generated from two related protein structures and assessed with state-of-the-art approaches. An analysis of the interactions of the variant Residue 223 in the proposed 3D model highlighted the importance of this position. Modeling predictions were consistent with the serologic and clinical data obtained for the D antigen with a substitution of Amino Acid 223. CONCLUSION: We used a 3D structural model to evaluate the effect of the p.Phe223 substitution on the conformation of the RhD protein. This model shed light on the influence of substitutions on the structure of the RhD protein and the associated alloimmunization risk. These initial findings indicate that the p.Phe223Ser variant can be considered partial.

We describe two patients who received secukinumab for clinically presumed psoriasis, but were subsequently diagnosed with mycosis fungoides (MF) following skin biopsies triggered by skin deterioration while on secukinumab. Previous studies suggested decreased numbers of regulatory T cells (Tregs) with increasing stage of MF, which may lead to the shift in the Treg/Th17 balance towards the Th17 pathway. Theoretically, the use of IL-17 monoclonal antibodies to inhibit Th17 pathway may lead to further immunosuppression and disease progression in cutaneous T-cell lymphoma (CTCL) by shifting the balance towards Tregs, although this hypothesis has not been proven. With uncertainty over the role of IL-17 and Treg/Th17 as well as diagnostic challenges in CTCL, we recommend that patients should have a confirmatory skin biopsy prior to the commencement of biologic therapy.

AB - Diffusion Monte Carlo (DMC) simulations have been used to obtain quantum zero point energies of methanol and all its isotopologs and isotopomers, using a new, accurate semi-global potential energy surface. This potential energy surface is a precise, permutationally invariant fit to 6676 ab initio energies, obtained at the CCSD(T)-F12b/aug-cc-pVDZ level of theory. Quantum zero-point energies of deuterated methanol isotopomers are very close to each other and so a simple statistical argument can be used to estimate the populations of each isotopomer at very low-temperatures. The DMC simulations also indicate that there is virtually zero probability for H/D exchange in the zero-point state.

AB - A well-established oxidative addition of organic halides (R-X) to N-heterocyclic carbene (NHC) complexes of palladium(0) leads to formation of (NHC)(R)PdII (X)L species, the key intermediates in a large variety of synthetically useful cross coupling reactions. Typical consideration of the cross-coupling catalytic cycle is based on the assumption of intrinsic stability of these species, where the subsequent steps involve coordination of the second reacting partner. Thus, high stability of the intermediate (NHC)(R)PdII (X)L species is usually taken for granted. In the present study it is discussed that such intermediates are prone to non-classical R-NHC intramolecular coupling process (R = Me, Ph, Vinyl, Ethynyl) that results in removal of NHC ligand and generation of another type of Pd catalytic system. DFT calculations (BP86, TPSS, PBE1PBE, B3LYP, M06, wB97X-D) clearly show that outcome of R-NHC coupling process is not only determined by chemical nature of the organic substituent R, but also strongly depends on the type of solvent. The reaction is most favorable in polar solvents, whereas the non-polar solvents render the products less stable. (c) 2019 Wiley Periodicals, Inc. PMID- 30284293 TI - Simulations of NaCl Aggregation from Solution: Solvent Determines Topography of Free Energy Landscape. AB - The partition-enabled analysis of cluster histograms (PEACH) method is used to calculate the free energy surface of NaCl aggregation using cluster statistics from MD simulations of small systems (40-90 ions plus solvent) in four solvents. In all cases (pure methanol, pure water, and two methanol/water mixtures) NaCl clusters show a transition from amorphous to rocksalt structure with increasing cluster size. The crossover sizes, and the apparent kinetic barrier to ordering, increase with increasing water content. Implications for the proposed two-step mechanism of NaCl crystal nucleation (in which the ordered structure emerges from a large disordered cluster), and how this mechanism might depend on solvent and on degree of supersaturation, are discussed. In pure water, nonideal crowding effects that promote clustering are identified from systematic concentration dependent deviations between simulation results and the PEACH model fit. In contrast, the ability of PEACH to fit aggregation statistics in mixed solvents is consistent with negligible interactions between ions in different clusters. (c) 2018 Wiley Periodicals, Inc. PMID- 30284294 TI - Reduction of OH vibrational frequencies in amino acids by positron attachment. AB - Positron affinities have been calculated for five amino acid molecules (asparagine, cysteine, glycine, proline, and serine) with the intramolecular ?COOH...NH2 ? hydrogen-bonded motif as a function of the OH distance using two computational methods, namely multicomponent molecular orbital theory and pseudopotential model. Since the elongation of the carboxylic OH bond leads to the formation of highly polarized zwitterionic amino acid with ?COO- ...NH3 + ? structure, the calculated positron affinity significantly increases with the elongation of the OH distance. This indicates that the OH bond strength is significantly weakened by positron attachment. We discuss the reduction of OH vibrational frequencies using effective one-dimensional potential energy curves for neutral and positron-attached amino acid molecules. (c) 2018 Wiley Periodicals, Inc. PMID- 30284295 TI - Attraction between electrophilic caps: A counterintuitive case of noncovalent interactions. AB - Intermolecular attractive interaction between electrophilic sites is a counterintuitive phenomenon, as the electrostatic interaction therein is repulsive and destabilizing. Here, we confirm this phenomenon in four representative complexes, using state-of-the-art quantum mechanical methods. By employing the block-localized wavefunction (BLW) method, which can turn off intermolecular charge transfer interactions, we profoundly demonstrated the significance of charge transfer interactions in these seemingly counterintuitive complexes. Indeed, after being "turned off" the intermolecular charge transfer interaction in, for example, the FNSi...BrF complex, the originally attractive intermolecular interaction turns to be repulsive. The energy decomposition approach based on the BLW method (BLW-ED) can partition the overall stability gained on the formation of intermolecular noncovalent interaction into several physically meaningful components. According to the BLW-ED analysis, the electrostatic repulsion in these counterintuitive cases is overwhelmed by the stabilizing polarization, dispersion interaction, and most importantly, the charge transfer interaction, resulting in the eventual counterintuitive overall attraction. The present study suggests that, predicting bonding sites of noncovalent interactions using only the "hole" concept may be not universally sufficient, because other significant stabilizing factors will contribute to the stability and sometimes, play even bigger roles than the electrostatic interaction and consequently govern the complex structures.

PMID- 30284296 TI - Mechanistic insight on water and substrate catalyzed the synthesis of 3-(1H-indol 3-yl)-2-(4-methoxybenzyl)isoindolin-1-one: Driving by noncovalent interactions. AB - The mechanisms of the synthesis of 2-substituted-3-(1H-indol-3-yl)-isoindolin-1 one derivatives have been investigated theoretically under unassisted, self assisted, and water-assisted conditions. Being different from previously proposed catalyst-free by Hu et al., our results show that the title mechanism can be altered and accelerated by solvent and substrate 2. Two types of mechanisms have been developed by DFT calculations differ in the reaction sequence of substrates 1 with 3 (M1) or 2 (M2) followed by 2 (M1) or 3 (M2), and water-assisted M1 is the most favored one. It was found that the nucleophilicity of substrate 3 is stronger than that of 2. Our calculations suggest that the water-assisted pathway in M1 is the most favorable case, which undergoes nucleophilic addition and H shift, C-N bond formation and water elimination, and intramolecular cyclization and water elimination. The rate-determining step is the nucleophilic attack process. Moreover, we also explored the effect of nucleophilic attack of the nitrogen of (4-methoxyphenyl)methanamine on hydroxyl or carbonyl group carbon of phthalaldehydic acid on the activation energy. More importantly, we found that water molecules play a critical role in the whole reaction, not only act as solvent but also as an efficient catalyst, proton shuttle, and stabilizer to stabilize the structures of transition states and intermediates via pi...H-O, O...H-N, O...H-C, and O...H-O interactions. The origin of the different reactivity of M1 and M2 is ascribed to the pivotal noncovalent interactions exist between catalyst (water and substrate 2) and reactants. (c) 2018 Wiley Periodicals, Inc. PMID- 30284297 TI - Guideline-directed statin intensification in patients with new or worsening symptoms of peripheral artery disease. AB - BACKGROUND: The ACC/AHA cholesterol guidelines recommend patients with peripheral artery disease (PAD) be treated with a moderate to high-intensity statin. The extent to which patients with new or worsening PAD symptoms are offered guideline therapy is unknown. HYPOTHESIS: There is significant variability in rate of guideline-directed statin intensification across clinical practices. METHODS: In the PORTRAIT registry, patterns of statin therapy were assessed in 1144 patients at 16 PAD specialty clinics between June 2011 and December 2015 before and after an evaluation for new or worsening claudication symptoms. We documented whether patients were treated with a guideline statin as well as the incidence of statin intensification. Statin intensification was defined as transitioning from no statin or low-intensity statin to moderate or high-intensity statin treatment. Patient factors associated with intensification were examined. Site and provider level variation in intensification was summarized using an adjusted median odds ratio (aMOR). RESULTS: Among 1144 patients, 810 (70.8%) were initially on guideline therapy compared to 334 (29.2%) that were not. In the latter, 103 (30.8%) received intensification following evaluation. Patients with typical symptoms displayed greater odds of intensification (OR 3.74; 95% CI: 1.23-11.41) while older patients had lower odds of intensification (OR 0.60/decade; 95% CI: 0.41-0.88). Site variability for statin intensification was observed across sites (aMOR = 3.15; 95% CI 1.22-9.60, [P = 0.02]) but not providers (aMOR = 1.89; 95% CI 1.00-3.90, [P = 0.14]). CONCLUSIONS: Most patients evaluated at a PAD specialty clinic for new or worsening claudication symptoms arrived on guideline statin therapy. Only 31% not receiving appropriate therapy underwent statin intensification. These findings highlight an important opportunity to optimize medical therapy for patients with PAD. PMID- 30284298 TI - Neprilysin levels at the acute phase of ST-elevation myocardial infarction. AB - BACKGROUND: Several preliminary analyses suggested an association between neprilysin levels and myocardial infarction. HYPOTHESIS: The objective was to assess whether Neprilysin (NEP) plasma levels following reperfusion might be a surrogate for infarct size (IS) or predict adverse outcomes in acute ST-segment elevation myocardial infarction (STEMI) patients. METHODS: We measured NEP levels in a prospective cohort of 203 patients with STEMI referred for primary percutaneous coronary intervention. Circulating soluble NEP was measured by ELISA at admission (t0) and four hours later (t4) following reperfusion and on 7 times points (t0, t4, t12, t24, t48, day 7 and day 30) in a subset of 21 patients. Infarct size (IS) and left ejection fraction (LVEF) were measured at one month by cardiac magnetic resonance (CMR). Adverse cardiovascular outcomes were collected at 12-month follow-up. RESULTS: Median t0 and t4 NEP levels in 203 patients were respectively 88.3 pg/mL (IQR [14; 375.4]) and 101.5 pg/mL (IQR [18.5; 423.8]). These levels remained unchanged over one month (p=0.70). NEP levels did not correlate significantly with IS (p=0.51) or LVEF (p=0.34). There was no correlation between NEP and troponin, creatine kinase and interleukin-6 levels at h0 and h4. NEP levels above the median were not associated with adverse outcomes at follow-up (HR= 1.28, 95%CI [0.69; 2.37]; p=0.42). CONCLUSIONS: NEP serum levels were widely distributed and did not change significantly in the first hours and one-month period following reperfusion in STEMI patients. There was no significant relationship with markers of infarct size and inflammation, and one year adverse outcomes. PMID- 30284299 TI - Evaluation of cystatin C and neutrophil gelatinase-associated lipocalin as predictors of mortality in patients undergoing percutaneous mitral valve repair (MitraClip). AB - BACKGROUND: Compromised renal function is a major risk factor that is strongly associated with poor outcome in patients with mitral regurgitation (MR) and heart failure. Cystatin C, a cysteine protease inhibitor, has been used as a specific and sensitive biomarker of renal function. Neutrophil gelatinase-associated lipocalin (NGAL) is another sensitive biomarker that specifically indicates functional and structural kidney damage. The aim of the present study was to determine the predictive value of serum cystatin C and urinary NGAL as indicators of mortality in patients undergoing percutaneous mitral valve repair (PMVR). METHODS: A total of 120 consecutive patients (age: 77.3 years [+/-11.2]) undergoing PMVR using the MitraClip system were included in this study. Venous blood and urinary samples were collected for biomarker analysis prior to PMVR. Physiological parameters, medication use, safety events, and all-cause mortality were assessed 12 months after the procedure. RESULTS: Twelve months after PMVR, there was a significant reduction in the severity of MR (P < 0.001), and an improvement in the New York Heart Association class (P < 0.01) was documented. Baseline levels of serum cystatin C (nonsurvivors: 2.4 mg/L [interquartile, IQR: 1.7;3.1] vs survivors: 1.7 mg/L [IQR: 1,3;2.1], P < 0.001) and urinary NGAL (nonsurvivors: 242.0 ng/mL [IQR: 154.5;281.5] vs survivors: 132.0 ng/mL [IQR:107.0;177.3], P < 0.001) were significantly higher in patients who died during the 12-month follow-up period. CONCLUSION: Cystatin C and urinary NGAL were found to be predictors of long-term mortality in high-risk patients undergoing PMVR. Thus, cystatin C and NGAL assessment may be helpful in risk stratification in patients undergoing PMVR. PMID- 30284301 TI - Impact of Atrial Fibrillation on patients hospitalized for Acute Myocarditis: Insights from a nationally-representative United States cohort. AB - BACKGROUND: Atrial fibrillation (AF) is associated with increased all-cause mortality in the general population. However, the impact of atrial fibrillation on the in-hospital outcomes of acute myocarditis patients is not well characterized. METHODS: Patients (age >=18 years) with a primary diagnosis of acute myocarditis in the National Inpatient Sample (NIS) from 2007 to 2014 were included, using the ICD-9-CM diagnostic codes. We compared the in-hospital outcomes between the AF group and propensity score-matched control group without AF. RESULTS: AF was reported in 602 (9%) of the acute myocarditis patients. Compared to those without AF, acute myocarditis patients with AF experienced higher in-hospital mortality (odds ratio [OR] 1.7, 95% CI 1.1 to 2.7, p = 0.02). AF was associated with higher risk of cardiogenic shock (OR 1.9, 95% CI 1.3 to 2.8, p < 0.001), cardiac tamponade (OR 5.6, 95% CI 1.2 to 25.3, p = 0.002) and acute kidney injury (1.6, 95% CI 1.1 to 2.1, p = 0.02). Furthermore, patients with AF were more likely to have non-routine hospital discharge (31.6% Vs. 38.4% p = 0.02), longer length of stay and higher cost of hospitalization. CONCLUSIONS: AF was associated with increased risk of in-hospital mortality and complications in patients admitted to the hospital with acute myocarditis.

AB - (12/12)CASPT2, (16/14)CASPT2, B3LYP, and CCSD(T) calculations have been carried out on 1,8-Naphthoquinone (1,8-NQ), to predict the low-lying electronic states and their relative energies in this non-Kekule quinone diradical. CASPT2 predicts a 1 A1 ground state, with three other electronic states-3 B2 , 3 B1 , and 1 B1 within about 10 kcal/mol of the ground state in energy. On the basis of the results of these calculations, it is predicted that NIPES experiments on 1,8-NQ * will find that 1,8-NQ is a diradical with a singlet ground state.

PMID- 30284302 TI - A paired trial comparing mononuclear cell collection in two machines for further inactivation through an inline or offline extracorporeal photopheresis procedure. AB - BACKGROUND: Extracorporeal photopheresis (ECP) is an effective treatment. However, protocols differ widely, and some questions, such as the number of cells to be collected or the number of ECP treatment days per treatment cycle, are still unsolved. The aim of this study was to compare a multistep (offline) (Spectra Optia and Macogenic G2) against an integrated (inline) ECP system (Therakos Cellex system) with respect to mononuclear cell (MNC) collection. STUDY DESIGN AND METHODS: The number and quality parameters of the MNC products collected were evaluated together with some machine parameters, such as collection time. Comparisons were made through paired sample analysis with the t test. RESULTS: Fourteen patients underwent 15 double-paired procedures using both ECP protocols. The average MNC collected in the multistep procedure was 77.4 * 108 , four times more than in the integrated procedure (18.5 * 108 ). MNC purity (84.4% vs. 63.8%) and enrichment (27.9 vs. 5.9) in the product collected were also higher in the multistep procedure. The whole ECP time was higher in the multistep than in the integrated procedure (272 vs. 106 min), but the calculated time to collect 25 * 108 MNCs in the multistep was shorter compared with the one step procedure (77.8 vs. 172 min). All these differences between the two protocols were statistically significant. CONCLUSIONS: These two ECP protocols are different with respect to MNC collection and length of procedure. Some unresolved questions, such as the better MNC dose to inactivate or the number of consecutive days that ECP should be performed for optimal clinical efficacy, require further review. PMID- 30284303 TI - A variant RhAG protein encoded by the RHAG*572A allele causes serological weak D expression while maintaining normal RhCE phenotypes. AB - BACKGROUND: The molecular events resulting in a weak D phenotype include missense mutations, in-frame insertion, or deletion mutations of the RHD gene and hybrid RHD-CE-D hybrid alleles. Mutations in genes encoding the proteins that are required for proper membrane expression of Rh proteins, such as RhAG and ankyrin 1, can lead to absent or weakened expression of Rh antigens. STUDY DESIGN AND METHODS: Blood sample from a Chinese blood donor with a serological weak D phenotype was collected. RhAG antigen expression, RhD, and RhCE phenotypes were determined. Analysis of the RHD and RHCE genotypes by RH multiplex ligation dependent probe amplification (MLPA), Sanger sequencing of the RHD exons, and next-generation sequencing (NGS) of the RHAG and ANK1 exons were performed. Expression studies in vitro were conducted by lentivirally transducing the mutant RHAG*572A or wild-type RHAG, in combination with either RHD or RHCE constructs, into HEK 293 T cells. The expression of RhAG, RhD, and RhCE antigens was analyzed by flow cytometry. RESULTS: Serological weak D and normal C + c- E- e + phenotypes, normal CCDDee genotype determined by RH-MLPA, and normal sequence of the RHD gene by Sanger sequencing were demonstrated. A homozygous variant (c.572G > A, p.Arg191Gln) of the RHAG gene was revealed by NGS analysis. Normal RhAG, weak RhD, and normal RhCE antigens were detected in cells transduced with the mutant RHAG*572A, the mutant RHAG*572A and RHD, and the mutant RHAG*572A and RHCE constructs, respectively. CONCLUSION: The homozygous presence of RHAG*572A allele results in weak D expression. It does not affect RhCE expression. PMID- 30284304 TI - Turning the simulation session upside down: the supervisor plays the resident. PMID- 30284306 TI - A bulk adjusted linear combination of atomic orbitals (BA-LCAO) approach for nanoparticles. AB - We describe a bulk adjusted linear combination of atomic orbitals (BA-LCAO) approach for nanoparticles. In this method, we apply a many-body scaling function (in similar manner as in the environment-modified total energy based tight binding method) to the DFT-derived diatomic AO interaction potentials (like in the conventional orbital-based density-functional tight binding approach) strictly according to atomic valences acquired naturally in a bulk structure. This modification, (a) facilitates all atom orbital-based electronic structure calculations of charge carrier dynamics in nanoscale structures with a molecular acceptor, and (b) allows to closely match high-level density functional calculation data (previously adjusted to the available experimental findings) for bulk structures. To advance practical application of the BA-LCAO approach we parameterize the Hamiltonian of wurtzite CdSe by fitting its band structure to a high-level DFT reference, corrected for experimentally measured band edges. Here, unlike in conventional DFTB approach, we: (1) use hydrogen-like AOs for the basis as exact atomic eigenfunctions, while orbital energies of which are taken from experimentally measured ionization potentials, and (2) parameterize the many-body scaling functions rather than the atomic wavefunctions. Development of this approach and parameters is guided by our goals to devise a method capable of simultaneously treating the problems of (i) interfacial electron/hole transfer between finite, variable size nanoparticles and electron scavenging molecules, and (ii) high-energy electronic transitions (Auger transitions) that mediate multi-exciton decay in quantum dots. Electronic structure results are described for CdSe quantum dots of various sizes. (c) 2018 Wiley Periodicals, Inc. PMID- 30284305 TI - Comparison of adiposity indices in relation to prehypertension by age and gender: A community-based survey in Henan, China. AB - BACKGROUND: To compare the efficiency of bioelectrical indices (visceral fat index [VFI], percentage body fat [PBF]) and anthropometric indices (body mass index, waist circumference, waist-to-height ratio, a body shape index ) in the relation to prehypertension (120-139/80-89 mm Hg) among the Chinese population. METHODS: Using stratified multistage random sampling method, a general population based sample of 11 175 adults in Henan province were selected from 2013 to 2015. The individuals were divided into three categories by blood pressure levels: normotension (<120 and 80 mm Hg), stage 1 prehypertension (120-129/80-84 mm Hg) and stage 2 prehypertension (130-139/85-89 mm Hg). RESULTS: VFI and PBF tended to increase with age in men and women. However, for each age-specific group, men tended to have higher VFI than women (all P < 0.01) and women tended to have greater PBF (all P < 0.0001). The odds ratios (OR) and area under the receiver operating characteristic curves for prehypertension associated with adiposity indices declined with age. VFI and PBF showed higher standardized adjusted ORs for prehypertension in young (~40 years) men (VFI: 2.02-3.05; PBF: 1.82-2.80) and young women (VFI: 1.90-2.58; PBF:1.70-2.29). Moreover, based on Youden's index, VFI and PBF exhibited the superiority for identifying prehypertension in men (0.20-0.32) and women (0.31-0.39), respectively. CONCLUSION: In summary, there was stronger association of VFI and PBF with prehypertension in men than in women, respectively, especially for young adults. PMID- 30284307 TI - Contrast-Enhanced Ultrasound With Perflubutane for Sentinel Lymph Node Mapping in Cutaneous Melanoma: A Pilot Study. AB - OBJECTIVE: To study the feasibility of contrast-enhanced ultrasound (CEUS) for identification of SLN associated with cutaneous melanoma. STUDY DESIGN: Single arm pilot study in a swine animal model. METHODS: One milliliter of perflubutane (Sonazoid, GE Healthcare, Milwaukee, WI) was injected into the peritumoral dermis in five swine with cutaneous melanoma. Ultrasonography was used to follow enhancing lymphatic channels to lymph nodes (LN). Intradermal injection of vital blue (VB) dye was used as a positive control. LN identified by either method were excised and examined histologically. RESULTS: There were five primary cutaneous melanomas with mean area of 4.36 +/- 4.75 cm2 and Breslow depth of 3.6 +/- 1.5 mm. Six possible sentinel lymph node (SLN)s were identified with CEUS, and nine were identified with VB. SLN averaged 12.44 +/- 6.15 cm from the primary tumor. Four of six (67%) SLNs identified by CEUS and four of nine (44%) candidate SLNs identified by VB contained histologically confirmed metastatic melanoma. All six CEUS-identified SLNs were also identified with VB. Two LNs not containing melanoma were identified by CEUS; three were identified with VB. In all SLN with metastases, metastatic cells were scattered throughout the LN and not clustered in a discrete mass. CONCLUSION: CEUS with perflubutane feasibly identifies SLN associated with cutaneous melanoma and may be a useful adjunct technology in facilitating precise SLN dissection. Our work supports a clinical trial investigating the use of CEUS for this application. LEVEL OF EVIDENCE: NA. Laryngoscope, 2018. PMID- 30284308 TI - Exploration of Carbon Allotropes with Four-membered Ring Structures on Quantum Chemical Potential Energy Surfaces. AB - The existence of a new carbon allotrope family with four-membered rings as a key unit has been recently predicted with quantum chemical calculations. This family includes carbon allotropes in prism-, polymerized prism-, sheet-, tube-, and wavy forms. An atypical bond property has been observed in this series of carbon structures, which differs from the typical sp3 , sp2 , and sp hybridizations. The lowest energy barrier from some of the equilibrium states of the carbon structures has been determined with the SHS-ADDF (scaled-hypersphere-search combined with the anharmonic downward distortion following) method within the GRRM software program package. The height of the barriers indicates that the well is deep enough for the carbon structures to exist. This class of carbon allotropes is expected to be energy-reservoirs with extra energy of 100-350 kJ mol-1 per one carbon atom. This article presents the structures, energies and reactivity of the carbon allotropes with four-membered ring structures as well as the background of the findings in the context of the global exploration of potential energy surfaces.

AB - Lignifications in secondary cell walls play a significant role in defense mechanisms of plants against the invading pathogens. In the present study, we investigated Trichoderma strain specific lignifications in chickpea plants pre treated with 10 potential Trichoderma strains and subsequently challenged with the wilt pathogen Fusarium oxysporum f. sp. ciceris (Foc). Trichoderma-induced lignifications in chickpea were observed through histochemical staining and expression of some genes of the lignin biosynthetic pathway. Lignifications were observed in transverse sections of shoots near the soil line through histochemical staining and expression pattern of the target genes was observed in root tissues through semi quantitative RT-PCR at different time intervals after inoculation of F. oxysporum f. sp. ciceris. Lignin deposition and expression pattern of the target genes were variable in each treatment. Lignifications were enhanced in all 10 Trichoderma strain treated and F. oxysporum f. sp. ciceris challenged chickpea plants. However, four Trichoderma strains viz., T-42, MV-41, DFL, and RO, triggered significantly high lignifications compared to the other six strains. Time course studies showed that effective Trichoderma isolates induced lignifications very early compared to the other strains and the process of lignifications nearly completes within 6 days of pathogen challenge. Thus, from the results it can be concluded that effective Trichoderma strains trigger lignifications very early in chickpea under Foc challenge and provide better protection to chickpea plants. PMID- 30284309 TI - Characterization of a novel bacteriophage specific to Exiguobacterium indicum isolated from a plateau eutrophic lake. AB - Exiguobacterium is a versatile genus with potential in industry and agriculture. No bacteriophage that infects Exiguobacterium has been reported, despite its potential impacts on the utilization of Exiguobacterium. E. indicum EI9 was isolated from Dianchi Lake, a plateau eutrophic lake in China, which can significantly inhibit the growth of Microcystis aeruginosa. To isolate and characterize Exiguobacterium-infecting bacteriophage, a virulent bacteriophage, DCEIV-9 that specifically infects E. indicum EI9 was isolated from Dianchi lake water sample. DCEIV-9 produced tiny, round, and clear plaques with 0.5-1 mm in diameter. Electron microscopy showed that DCEIV-9 is a typical representative of the Siphoviridae, with an icosahedral head (56 nm in diameter) and a non contractile tail (163 nm in length). Based on a one-step growth curve, latent period of 20 min and burst size of 51 PFU/infected cell were determined. DCEIV-9 was sensitive to temperature over 50 degrees C and prefers acid environment. DCEIV-9 was extremely sensitive to proteinase K, chloroform, ethanol, Triton X 100 but not sensitive to SDS. Restriction endonucleases analysis indicated that DCEIV-9 is a dsDNA virus. DCEIV-9 can only infect E. indicum, indicates that it has a narrow host range. DCEIV-9 is a potential new species.

AB - OBJECTIVE: To determine whether investment in preventive measures by a Colombian insurer reduces rates of work-related injuries and results in positive returns from these investments. METHODS: The study is based on monthly panel data of 2011 2015 of 303 medium and large companies affiliated with a private insurer in Colombia. We undertook regression modeling analysis to assess the effectiveness of incremental investments in occupational health and safety (OHS) prevention measures. The cost-benefit analysis is from the insurer's perspective. RESULTS: Investment in OHS per full-time equivalent was statistically significant at the 1% level. We estimated that 4919 injuries were averted through these investments, resulting in the avoidance of $3 949 957 in costs. Our results suggest that the investments were worth undertaking from the insurer's perspective. CONCLUSIONS: This paper provides new empirical evidence on the effectiveness and cost-benefit of OHS investments in a middle-income country. Incremental investment in OHS can be effective and cost-beneficial. PMID- 30284312 TI - Two weeks of high-fat feeding disturb lipid and cholesterol molecular markers. AB - Metabolic disorders are often associated with liver steatosis and increased plasma cholesterol levels. However, the link between excessive lipid accumulation and impairments in cholesterol metabolism remains uninvestigated in the liver. Short term of high-fat diet (HFD) was previously shown to promote excessive lipid accumulation prior to the development of metabolic disorders. The present study intended to characterize how increases in liver fat alter the expression of several key regulators of hepatic cholesterol metabolism in response to a short term HFD. Wistar rats were randomly submitted either to HFD (n = 8) or a regular chow diet (n = 8) for 14 days. Increases in triglycerides were highly significant (P < 0.01) in the liver but marginal in the plasma of HFD rats. In contrast, the HFD resulted in higher (P < 0.01) cholesterol levels in plasma but not in liver samples. Gene expression of key markers involved in cholesterol uptake (LDL particles) including low-density lipoprotein receptor-related protein-1 (LRP-1) and protein convertase subtilisin/kexin type 9 (PCSK9) along with ATP-binding cassette, superfamily G, member 5 (ABCG5) involved in cholesterol exportation via bile ducts was found to be higher (P < 0.05) in response to the HFD. In contrast, expression of 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR), involved in cholesterol synthesis, was downregulated in the liver. The data support the concept that excessive accumulation of lipids promptly alters the expression of key genes regulating cholesterol metabolism in the liver. On a clinical point of view, this indicates that increases in plasma cholesterol occur after a short term HFD. PMID- 30284314 TI - Meta-analysis of non-linear exposure-outcome relationships using individual participant data: A comparison of two methods. AB - Non-linear exposure-outcome relationships such as between body mass index (BMI) and mortality are common. They are best explored as continuous functions using individual participant data from multiple studies. We explore two two-stage methods for meta-analysis of such relationships, where the confounder-adjusted relationship is first estimated in a non-linear regression model in each study, then combined across studies. The "metacurve" approach combines the estimated curves using multiple meta-analyses of the relative effect between a given exposure level and a reference level. The "mvmeta" approach combines the estimated model parameters in a single multivariate meta-analysis. Both methods allow the exposure-outcome relationship to differ across studies. Using theoretical arguments, we show that the methods differ most when covariate distributions differ across studies; using simulated data, we show that mvmeta gains precision but metacurve is more robust to model mis-specification. We then compare the two methods using data from the Emerging Risk Factors Collaboration on BMI, coronary heart disease events, and all-cause mortality (>80 cohorts, >18 000 events). For each outcome, we model BMI using fractional polynomials of degree 2 in each study, with adjustment for confounders. For metacurve, the powers defining the fractional polynomials may be study-specific or common across studies. For coronary heart disease, metacurve with common powers and mvmeta correctly identify a small increase in risk in the lowest levels of BMI, but metacurve with study-specific powers does not. For all-cause mortality, all methods identify a steep U-shape. The metacurve and mvmeta methods perform well in combining complex exposure-disease relationships across studies.

This case report and literature review provides keys to establishing the above diagnosis and discusses the current controversies concerning the use of antifungal drugs in this age group. PMID- 30284316 TI - Effects of dietary amino acid supplementation on measures of whole-body and muscle protein metabolism in aged horses. AB - The objective of this study was to examine markers of whole-body and muscle protein metabolism in aged horses fed a diet typical for North American aged horses, supplemented with amino acids. In a replicated Latin square design, six aged horses (20 +/- 1.1 years) were studied while receiving each of three isocaloric, isonitrogenous diets, a control treatment concentrate (CON; 100 mg/kg 1 BW day-1 lysine, 84 mg kg-1 day-1 threonine, 51 mg kg-1 day-1 methionine), LYS/THR (134 mg kg-1 BW day-1 lysine, 110 mg kg-1 BW day-1 threonine, 52 mg kg-1 BW day-1 methionine) and LYS/THR/MET (132 mg kg-1 BW day-1 lysine, 112 mg kg-1 BW day-1 threonine, 62 mg kg-1 BW day-1 methionine). In each 15-days period, urine and faeces were collected for assessment of nitrogen balance. Blood samples were collected before and after feeding for analysis of plasma urea nitrogen (PUN), glucose, insulin and plasma amino acid concentrations. Skeletal muscle samples were collected for measurement of proteins associated with muscle protein synthesis and degradation, and horses underwent stable isotope infusion procedures for comparison of differences in whole-body rates of protein synthesis and degradation. There was no effect of treatment on relative abundance of proteins involved in protein synthesis, nitrogen retention or phenylalanine kinetics. PUN concentrations tended to be higher for LYS/THR (p = 0.054) and were higher for LYS/THR/MET (p = 0.0056) than for CON. Atrogin-1 abundance tended to be higher in the post-absorptive state for the CON treatment (p = 0.07), indicating that amino acid supplementation resulted in less muscle protein degradation when horses were in the post-absorptive state. However, lack of differences in nitrogen retention and phenylalanine kinetics indicated that whole body protein metabolism was not improved, and higher PUN concentrations in the supplemented diets suggest that the supplemented amino acids may have been catabolized. Amino acid availability was not limiting protein synthesis in the sedentary aged horses in this study when fed the CON diet. PMID- 30284317 TI - Uranium transfer and accumulation in organs of Danio rerio after waterborne exposure alone or combined with diet-borne exposure. AB - Uranium (U) toxicity patterns for fish have been mainly determined under laboratory-controlled waterborne exposure conditions. Because fish can take up metals from water and diet under in situ exposure conditions, a waterborne U exposure experiment (20 MUg L-1 , 20 d) was conducted in the laboratory to investigate transfer efficiency and target organ distribution in zebrafish Danio rerio compared with combined waterborne exposure (20 MUg L-1 ) and diet-borne exposure (10.7 MUg g-1 ). 233 Uranium was used as a specific U isotope tracer for diet-borne exposure. Bioaccumulation was examined in the gills, liver, kidneys, intestine, and gonads of D. rerio. Concentrations in the organs after waterborne exposure were approximately 500 ng g-1 fresh weight, except in the intestine (> 10 MUg g-1 fresh wt) and the kidneys (200 ng g-1 fresh wt). No significant difference was observed between waterborne and diet-borne conditions. Trophic U transfer in organs was found but at a low level (< 10 ng g-1 fresh wt). Surprisingly, the intestine appeared to be the main target organ after both tested exposure modalities. The gonads (57% at 20 d) and the liver (41% at 20 d) showed the highest accumulated relative U burdens. Environ Toxicol Chem 2018;9999:1-9. (c) 2018 SETAC. PMID- 30284318 TI - Evaluation of the DGT technique for predicting uptake of metal mixtures by fathead minnow (Pimephales promelas) and yellow lampmussel (Lampsilis cariosa). AB - Diffusive gradients in thin films (DGT) were assessed for their predictive capability of fathead minnow and yellow lampmussel bioaccumulation in copper (Cu) and lead (Pb) mixed metal exposures. Nine treatments with a matrix of 3 Cu and 3 Pb concentrations were utilized. Exposures were coupled, with organisms and DGT exposed in tanks for 6 days. The Cu measured in fish, mussel, and DGT was found not to be influenced by Pb treatment, whereas Pb accumulation was impacted by the interaction of Cu and Pb treatment. The Pb accumulation increased with increasing Cu concentration, which was attributed to the different speciation of Cu and Pb in the water where Cu binds preferentially to ligands, decreasing its bioavailability and concomitantly displacing Pb from complexing sites. The DGT values were significantly correlated with accumulated Cu and Pb in the fish, but not with Pb in the mussel. In addition, DGT was determined to better predict aquatic organism bioaccumulation of Cu than the inorganic Cu fraction calculated by the speciation model, because DGT accumulated not only inorganic metal fractions but also complexes of metal and organic matter. The present study provides insights into metal speciation in polluted environments, extends the understanding of using DGT as a tool for estimating metal bioavailability, and provides implications for the selection of geochemical modeling, biological sampling, and passive sampling techniques for monitoring trace metal contamination.

PMID- 30284319 TI - Clinical efficacy of the graft free slit-window sinus floor elevation procedure: A 2-year randomized controlled clinical trial. AB - OBJECTIVE: Slit-window technique is a lateral approach sinus floor elevation (SFE) procedure that utilizes a rigid resorbable membrane in conjunction with stabilizing bony slits to tent the Schneiderian membrane without addition of grafting materials. The aim of this randomized clinical trial was to compare clinical and radiographic outcomes of the Slit-window SFE with those of SFE with bone grafting. MATERIAL AND METHODS: Thirty-three patients with 38 edentulous sites were included. Edentulous sites were randomly allocated to the Slit-window SFE or SFE with bone grafting. Simultaneous with SFE, each site received two dental implants. Implant stability quotient (ISQ) values were recorded at baseline and monthly visits for 8 months. The bone coverage and bone height gain at implant sites were recorded on cone beam computed tomography (CBCT) scans 6 and 24 months postoperatively. RESULTS: There were no significant differences in the mean ISQ values between the groups at any time point (p > 0.05). All implants in both groups were found to have complete bone coverage. Significant increases in the bone height were found 6 and 24 months postoperatively in both groups (p < 0.001). CONCLUSIONS: Within limitations of the present study, it can be concluded that the Slit-window SFE technique without the need for bone grafting resulted in sufficient bone height gain around implants placed simultaneous with the SFE procedures. The bone height around these implants was stable during the 2-year follow-up period. The treatment outcomes for these implants were comparable to those placed simultaneous with lateral approach SFE in conjunction with bone grafting. PMID- 30284320 TI - Sediment and Biota Trace Element Distribution in Streams Disturbed by Upland Industrial Activity. AB - Extensive industrial areas in headwater stream watersheds can severely impact the physical condition of streams and introduce contaminants. We compared 3 streams that received stormwater runoff and industrial effluents from industrial complexes to two reference streams. Reference streams provide a benchmark of comparison of geomorphic form and stability in coastal plain, sandy-bottomed streams as well as concentrations of trace elements in sediment and biota in the absence of industrial disturbance. We used crayfish (Cambarus latimanus, Procambarus raneyi, P. acutus) and crane fly larvae (Tipula) as biomonitors of 15 trace elements entering aquatic food webs. Streams with industrial areas were more scoured, deeply incised, and less stable. Sediment organic matter content broadly correlated to trace element accumulation, but fine sediments and organic matter were scoured from stream bottoms of disturbed streams. Trace element concentrations were higher in depositional zones than runs within all streams. Despite contaminant sources in the headwaters, trace element concentrations were generally not elevated in sediments of the eroded streams. However, element concentrations were frequently elevated in biota from these streams with taxonomic differences in accumulation amplified. In eroded, sand-bottomed coastal plain streams with unstable sediments, single snapshots of sediment trace element concentrations did not characterize well bioavailable trace elements. Biota that integrated exposures over time and space within their home ranges better detected bioavailable contaminants than sediment. This article is protected by copyright. All rights reserved. PMID- 30284321 TI - Achieving Thermo-Mechano-Opto-Responsive Bitemporal Colorful Luminescence via Multiplexing of Dual Lanthanides in Piezoelectric Particles and its Multidimensional Anticounterfeiting. AB - Optical characteristics of luminescent materials, including emission color (wavelength), lifetime, and excitation mode, play crucial roles in data communication and information security. Conventional luminescent materials generally display unicolor, unitemporal, and unimodal (occasionally bimodal) emission, resulting in low-level readout and decoding. The development of multicolor, multitemporal, and multimodal luminescence in a single material has long been considered to be a significant challenge. In this study, for the first time, the superior integration of colorful (red-orange-yellow-green), bitemporal (fluorescent and delayed), and four-modal (thermo-/mechano-motivated and upconverted/downshifted) emissions in a particular piezoelectric particle via optical multiplexing of dual-lanthanide dopants is demonstrated. The as-prepared versatile NaNbO3 :Pr3+ ,Er3+ luminescent microparticles shown are particularly suitable for embedding into polymer films to achieve waterproof, flexible/wearable and highly stretchable features, and synchronously to provide multidimensional codes that can be visually read-out using simple and commonly available tools (including the LED of a smartphone, pen writing, cooling-heating stimuli, and ultraviolet/near-infrared lamps). These findings offer unique insight for designing highly integrated stimuli-responsive luminophors and smart devices toward a wide variety of applications, particularly advanced anticounterfeiting technology. PMID- 30284322 TI - Biotransport of metallic trace elements from marine to terrestrial ecosystems by seabirds. AB - Physical systems, such as currents and winds, have traditionally been considered responsible for transporting contaminants. Although evidence is mounting that animals play a role in this process through their movements, we still know little about how such contaminant biotransport occurs and the extent of effects at deposition sites. In the present study, we address this question by studying how rhinoceros auklets (Cerorhinca monocerata), a seabird that occurs in immense colonies (~300 000 pairs at our study site, Teuri Island), affect contaminant levels at their colony and at nearby sites. More specifically, we hypothesize that contaminants are transported and deposited by seabirds at their colony and that these contaminants are passed on locally to the terrestrial ecosystem. To test this hypothesis, we analyzed the concentration of 9 heavy metal and metalloids, as well as delta13 C and delta15 N stable isotopes, in bird tissues, plants, and soil, both within and outside of the colony. The results show that rhinoceros auklets transport marine-derived mercury (Hg), possibly from their wintering location, and deposit Hg via their feces at their breeding site, thereby contaminating plants and soils within the breeding colony. The present study confirms not only that animals can transport contaminants from marine to terrestrial ecosystems, potentially over unexpectedly long distances, but also that bird tissues contribute locally to plant contamination.

AB - The self-controlled case series method assumes that adverse outcomes arise according to a non-homogeneous Poisson process. This implies that it is applicable to independent recurrent outcomes. However, the self-controlled case series method may also be applied to unique, non-recurrent outcomes or first outcomes only, in the limit where these become rare. We investigate this rare outcome assumption when the self-controlled case series method is applied to non recurrent outcomes. We study this requirement analytically and by simulation, and quantify what is meant by 'rare' in this context. In simulations we also apply the self-controlled risk interval design, a special case of the self-controlled case series design. To illustrate, we extract data on the incidence rate of some recurrent and non-recurrent outcomes within a defined study population to check whether outcomes are sufficiently rare for the rare outcome assumption to hold when applying the self-controlled case series method to first or unique outcomes. The main findings are that the relative bias should be no more than 5% when the cumulative incidence over total time observed is less than 0.1 per individual. Inclusion of age (or calendar time) effects will further reduce bias. Designs that begin observation with exposure maximise bias, whereas little or no bias will be apparent when there is no time trend in the distribution of exposures, or when exposure is central within time observed. PMID- 30284325 TI - Congenital malformations are associated with secondhand smoke among nonsmoking women: A meta-analysis. AB - BACKGROUND: The association between active maternal smoking and congenital malformations is well established, but little is known about the association between secondhand smoke and congenital malformations. Moreover, studies regarding the association between congenital malformations and secondhand smoke have not yielded consistent results. METHODS: In July 2018, we searched PubMed, EMBASE, and China Biology Medicine databases for observational studies characterizing the relationship between secondhand smoke and congenital malformations of offspring in nonsmoking women. Two reviewers independently decided on whether a study should be included, did data extraction, and assessed study quality. Pooled risks with 95% confidence intervals were calculated using either the fixed-effects models or random-effects models. Further subgroup analyses and sensitivity analyses were performed to explore the potential source of heterogeneity and to examine the robustness of risk estimates. RESULTS: Thirty three studies with a total of 31 944 cases and 32 335 controls were included. Secondhand smoke exposure was associated with an increased risk of congenital malformations (odds ratio = 1.92; 95% confidence interval 1.61-2.30). Secondhand smoke was correlated with significantly increased risk for digestive system (1.17 [1.05-1.32]), nervous system (1.74 [1.33-2.29]), and cardiovascular system (2.10 [1.32-3.35]) malformations and for oral clefts (1.87 [1.47-2.39]). CONCLUSIONS: Secondhand smoke exposure increases the risk for overall and several organ-system malformations. These findings highlight the necessity of improving community awareness to prevent secondhand smoke exposure during the preconception and conception periods. PMID- 30284324 TI - The myodural bridge in the common rock pigeon (Columbia livia): Morphology and possible physiological implications. AB - The dense connective tissue that connects muscles to the cervical spinal dura mater is known as the myodural bridge in human anatomy and has been a subject of interest to anatomists and clinicians. The myodural bridge was originally discovered in humans, and also has been observed in other mammals and in reptilian sauropsids. We investigated the existence of the myodural bridge in a bird, that is, the Common Rock Pigeon Columba livia, to expand the understanding of the structure and function of the myodural bridge. Gross anatomical dissection of seven specimens and histological analyses of the suboccipital region of eight specimens were performed. The rectus capitis dorsalis minor muscle joins occipital periosteal extensions and inserts with several dense connective tissue cords on the dorsal side of the dura mater of the cervical spinal cord. The myodural bridge consists primarily of collagen Type I fibres, suggesting that the myodural bridge can transmit strong tensional forces generated by the contraction of M. rectus capitis dorsalis minor to the dura mater. The pull on the dura mater may affect the circulation of the cerebrospinal fluid in the subarachnoid space of the spine. PMID- 30284326 TI - Sonographic appearances of adrenal schwannomas. AB - OBJECTIVE: To evaluate the sonographic ultrasound (US) appearances of adrenal gland schwannomas. MATERIALS AND METHODS: This was a retrospective analysis of 15 cases of schwannomas involving the adrenal gland. The following US features were assessed: size, border, echogenicity, homogeneity, intralesional cystic necrosis, presence of septa, intralesional calcification, posterior acoustic enhancement and blood supply. RESULTS: Of the 15 tumors, seven (46.7%) were located on the left side, and the remaining eight (53.3%) on the right side. The most frequent US appearance of adrenal schwannoma was a single, well-defined and isoechoic mass. The internal echotexture was homogeneous in 2 cases, and heterogeneous in 13 cases, with intralesional cystic areas (n = 11), septa (n = 10) or calcifications (n = 6). Posterior acoustic enhancement was seen in 12 of the 15 cases (80%). On color Doppler US, 86.7% (13/15) of the lesions did not show any vascularity. CONCLUSIONS: Adrenal schwannomas usually present on US as well defined isoechoic masses often with posterior acoustic enhancement, cystic necrosis with septa and poor blood supply. These appearances should suggest the diagnosis of adrenal schwannomas. Nevertheless, additional information from laboratory tests and CT or MR imaging may be required to avoid unnecessary surgery. PMID- 30284328 TI - Effects of Vitamin D levels and supplementation on atopic dermatitis: A systematic review. AB - BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin condition affecting 5%-20% of children worldwide. Studies suggested both a correlation between serum vitamin D (VD) levels and AD severity and a therapeutic potential role for VD supplementation. OBJECTIVES: To determine whether serum VD levels correlate with AD severity and the effects of supplementation for disease improvement in children. DATA SOURCES: Ovid MEDLINE, EMBASE, and Cochrane Library databases were searched. STUDY SELECTION: Publications with children 0-18 years old with AD and data evaluating effects of VD levels or supplementation on AD severity were included. DATA EXTRACTION: Author, year, inclusion criteria, study design, location, age, VD levels, VD supplementation regimens, and baseline and final disease severities were extracted. RESULTS: Of the 21 included publications, 15, 5, and 1 evaluated VD level, VD supplementation, and both factors with disease severity, respectively. There were 4 randomized control trials (RCTs), 5 cohort, 6 case-control, and 6 cross-sectional studies. A significant inverse correlation between VD level and severity was described in 62.5% (10/16) of studies. There were 67% (4/6) that reported a significant improvement in AD severity with supplementation. LIMITATIONS: Studies meeting inclusion criteria were limited. Furthermore, papers were heterogeneous in terms of location, season, and VD supplementation regimen. Language and publication bias was another potential limitation. CONCLUSION: In children, the majority of existing literature confirmed a link between serum VD levels and AD severity. Weak evidence was found supporting improvement of AD with VD supplementation. Future large-scale studies are needed to support our findings. PMID- 30284329 TI - A Scalable, High-Throughput, and Environmentally Benign Approach to Polymer Dielectrics Exhibiting Significantly Improved Capacitive Performance at High Temperatures. AB - High-temperature capability is critical for polymer dielectrics in the next generation capacitors demanded in harsh-environment electronics and electrical power applications. It is well recognized that the energy-storage capabilities of dielectrics are degraded drastically with increasing temperature due to the exponential increase of conduction loss. Here, a general and scalable method to enable significant improvement of the high-temperature capacitive performance of the current polymer dielectrics is reported. The high-temperature capacitive properties in terms of discharged energy density and the charge-discharge efficiency of the polymer films coated with SiO2 via plasma-enhanced chemical vapor deposition significantly outperform the neat polymers and rival or surpass the state-of-the-art high-temperature polymer nanocomposites that are prepared by tedious and low-throughput methods. Moreover, the surface modification of the dielectric films is carried out in conjunction with fast-throughput roll-to-roll processing under ambient conditions. The entire fabrication process neither involves any toxic chemicals nor generates any hazardous by-products. The integration of excellent performance, versatility, high productivity, low cost, and environmental friendliness in the present method offers an unprecedented opportunity for the development of scalable high-temperature polymer dielectrics. PMID- 30284330 TI - An Effective Dark-Vis-UV Ternary Biomimetic Switching Based on N3/Spiropyran Modified Nanochannels. AB - Many natural photomodulated nanochannels are investigated and are crucial for biological activity. Biomimetic nanochannels with a bistable conductance state under light stimulus are demonstrated. In this system, two molecules, cis-bis (4,4'-dicarboxy-2,2'-bipyridine) dithiocyanato ruthenium(II) (N3) and spiropyran 1'-(3-carboxypropyl)-3',3'-dimethyl-6-nitro-spiro[2H-1]benzopyran-2,2'-indoline (SP-COOH), each with unique photoresponsive properties, are modified in alumina nanochannels. The two segments of the hourglass-shaped alumina nanochannels are designated to graft a certain molecule. Under ultraviolet (UV) or visible light (vis) irradiation, electrons belonging to N3 are excited, resulting in negatively charged surfaces on the sides of nanochannels modified with N3 molecules. Only under UV stimulus, the conformation change of the SP-COOH molecules leads to positively charged surfaces of nanochannels in the SP-COOH occupied sides. Benefiting from the joint effect of N3 and SP-COOH, low, medium, and high (i.e., "0," "1," and "2") ternary levels of ion conductance are established under the dark-vis-UV alternate stimuli. The multistage current switching containing "0-1-2 0" and "0-1-2-1-0" procedures is stable and robust. Additionally, the diode-like ion transport behavior of the nanochannels could be exploited to support a multivalued logical gating with the management of light signals. PMID- 30284331 TI - Three-dimensional spin-echo-based black-blood MRA in the detection of vasospasm following subarachnoid hemorrhage. AB - BACKGROUND: Black-blood MR angiography (BBMRA), which utilizes a non-T1 contrast spin-echo type technique, has been expected to overcome several issues associated with time-of-flight (TOF) MRA. PURPOSE: To investigate the efficacy of BBMRA to detect vasospasms following subarachnoid hemorrhage (SAH). STUDY TYPE: Retrospective. SUBJECTS: Seventeen patients with SAH in their early posttreatment period. FIELD STRENGTH/SEQUENCE: BBMRA, which uses a volumetric isotropic turbo spin-echo acquisition (VISTA), and TOF-MRA on 1.5T scanners. ASSESSMENT: Visualization of supratentorial arteries and veins in BBMRA was rated on a 4 point scale by two neuroradiologists. Another neuroradiologist independently assessed TOF-MRA. The degree of the vasospasm was then evaluated using a 3-point scale by the same readers. The diagnostic performance of the MRAs was evaluated using computed tomography angiography (CTA) or digital subtraction angiography (DSA) as the standard of reference. STATISTICAL TESTS: Wilcoxon signed rank test, McNemar test, and Cohen's kappa coefficient. RESULTS: BBMRA provided superior visualization of the anterior and middle cerebral arteries than TOF-MRA (P < 0.05). The depiction of the veins was more pronounced on BBMRA (P < 0.01). Of the 166 arterial segments evaluated by CTA or DSA, 23 (13.9%) could not be assessed using TOF-MRA because of high signal hemorrhage, whereas BBMRA enabled visualization of all the segments. Vasospasm was confirmed in 30 segments by CTA or DSA. The sensitivity, specificity, and positive and negative predictive values were 73, 96, 76, and 95 for TOF-MRA and 91, 100, 100, and 98 for BBMRA, respectively (P = 0.13 for sensitivity, P = 0.06 for specificity). The agreement of the degree of vasospasm between MRA and the standard of reference, as indicated by kappa value, was 0.71 (95% confidence interval [CI], 0.55-0.87) for TOF-MRA and 0.91 (95% CI, 0.82-0.99) for BBMRA. DATA CONCLUSION: BBMRA, owing to its contrast properties, may be superior to TOF-MRA for the evaluation of intracranial arteries after SAH. LEVEL OF EVIDENCE: 3 Technical Efficacy: Stage 2. PMID- 30284332 TI - Modulating long-range energetics via helix stabilization: A case study using T4 lysozyme. AB - Cooperative protein folding requires distant regions of a protein to interact and provide mutual stabilization. The mechanism of this long-distance coupling remains poorly understood. Here, we use T4 lysozyme (T4L*) as a model to investigate long-range communications across two subdomains of a globular protein. T4L* is composed of two structurally distinct subdomains, although it behaves in a two-state manner at equilibrium. The subdomains of T4L* are connected via two topological connections: the N-terminal helix that is structurally part of the C-terminal subdomain (the A-helix) and a long helix that spans both subdomains (the C-helix). To understand the role that the C-helix plays in cooperative folding, we analyzed a circularly permuted version of T4L* (CP13*), whose subdomains are connected only by the C-helix. We demonstrate that when isolated as individual fragments, both subdomains of CP13* can fold autonomously into marginally stable conformations. The energetics of the N terminal subdomain depend on the formation of a salt bridge known to be important for stability in the full-length protein. We show that the energetic contribution of the salt bridge to the stability of the N-terminal fragment increases when the C-helix is stabilized, such as occurs upon folding of the C-terminal subdomain. These results suggest a model where long-range energetic coupling is mediated by helix stabilization and not specific tertiary interactions. PMID- 30284333 TI - The nature and timing of distress among post-treatment haematological cancer survivors. AB - Many people with haematological cancers will not meet the diagnostic criteria for a psychological disorder, but will still suffer distress during treatment and beyond. The current study aimed to explore the nature and timing of psychosocial distress experienced by haematological cancer survivors. Twenty-three post treatment haematological cancer survivors participated in a semi-structured interview. Data were analysed using thematic analysis which involved identifying, analysing and reporting themes. Four themes were identified: Apprehension about leaving the safety of the health care system comprises the struggles encountered when transitioning from patient to survivor, Uncertainty and life transitions in the post-treatment period encompasses the changes survivors face when attempting to re-enter their "normal" lives, Distress associated with ongoing physical problems or impairment describes issues associated with the ongoing physical sequelae, and Fear of recurrence encapsulates how the continuing threat of cancer recurrence impacted survivors. This study has found that distress is ongoing for many haematological cancer survivors in the post-treatment period. It is imperative that distress is identified and support offered to those in need to prevent further psychosocial issues. It is especially important to consider the psychosocial needs of survivors in the post-treatment stage who are discharged from the health system may be unsure where to seek help. PMID- 30284335 TI - Differential parameters between cytosolic 2-Cys peroxiredoxins, PRDX1 and PRDX2. AB - Peroxiredoxins are thiol-dependent peroxidases that function in peroxide detoxification and H2 O2 induced signaling. Among the six isoforms expressed in humans, PRDX1 and PRDX2 share 97% sequence similarity, 77% sequence identity including the active site, subcellular localization (cytosolic) but they hold different biological functions albeit associated with their peroxidase activity. Using recombinant human PRDX1 and PRDX2, the kinetics of oxidation and hyperoxidation with H2 O2 and peroxynitrite were followed by intrinsic fluorescence. At pH 7.4, the peroxidatic cysteine of both isoforms reacts nearly tenfold faster with H2 O2 than with peroxynitrite, and both reactions are orders of magnitude faster than with most protein thiols. For both isoforms, the sulfenic acids formed are in turn oxidized by H2 O2 with rate constants of ca 2 * 103 M-1 s-1 and by peroxynitrous acid significantly faster. As previously observed, a crucial difference between PRDX1 and PRDX2 is on the resolution step of the catalytic cycle, the rate of disulfide formation (11 s-1 for PRDX1, 0.2 s 1 for PRDX2, independent of the oxidant) which correlates with their different sensitivity to hyperoxidation. This kinetic pause opens different pathways on redox signaling for these isoforms. The longer lifetime of PRDX2 sulfenic acid allows it to react with other protein thiols to translate the signal via an intermediate mixed disulfide (involving its peroxidatic cysteine), whereas PRDX1 continues the cycle forming disulfide involving its resolving cysteine to function as a redox relay. In addition, the presence of C83 on PRDX1 imparts a difference on peroxidase activity upon peroxynitrite exposure that needs further study. PMID- 30284334 TI - Poly(ionic liquid)-Derived N-Doped Carbons with Hierarchical Porosity for Lithium and Sodium-Ion Batteries. AB - The performance of lithium- and sodium-ion batteries relies notably on the accessibility to carbon electrodes of controllable porous structure and chemical composition. This work reports a facile synthesis of well-defined N-doped porous carbons (NPCs) using a poly(ionic liquid) (PIL) as precursor, and graphene oxide (GO)-stabilized poly(methyl methacrylate) (PMMA) nanoparticles as sacrificial template. The GO-stabilized PMMA nanoparticles are first prepared and then decorated by a thin PIL coating before carbonization. The resulting NPCs reach a satisfactory specific surface area of up to 561 m2 g-1 and a hierarchically meso- and macroporous structure while keeping a nitrogen content of 2.6 wt%. Such NPCs deliver a high reversible charge/discharge capacity of 1013 mA h g-1 over 200 cycles at 0.4 A g-1 for lithium-ion batteries, and show a good capacity of 204 mA h g-1 over 100 cycles at 0.1 A g-1 for sodium-ion batteries.

BACKGROUND: Instruments to facilitate comprehensive and objective assessments of the cancer symptom experience in underrepresented populations are essential. METHODS: The Cancer Symptom Scale was translated into Spanish, and a back translation was conducted. During June 2016, a sample of 121 Hispanic Puerto Rican patients with any cancer diagnosis, all undergoing cancer treatments, completed four paper surveys. A subgroup of 15 patients agreed to complete the Spanish Cancer Symptom Scale a second time after a short delay of 1 to 2 hours. Construct validity and reliability (internal consistency via Cronbach alpha and test-retest reliability) was evaluated. RESULTS: All the Intensity Items of the Spanish Cancer Symptom Scale correlated significantly with the matched items on the MD Anderson Symptom Inventory. In a subgroup of 77 participants, each Cancer Symptom Scale subscale total of scores correlated significantly with the total scores from the Functional Assessment of Cancer Therapy-General. Discriminant validity was demonstrated between those receiving chemotherapy and those from post treatment. The Spanish Cancer Symptom Scale internal consistency reliability was 0.98. CONCLUSION: The Spanish Cancer Symptom Scale has excellent evidence of validity and reliability for assessing cancer-therapy-related symptoms. PMID- 30284337 TI - Throughput efficiency and service quality after process redesign at a cancer day care unit: Two sides of the coin? AB - This study was designed to focus on the patient perspective in a reorganisation of care processes at a cancer day care unit (CDU). The effects of dose banding and of taking blood samples one day (or more) before the day care treatment (on Day -1) are investigated in terms of throughput efficiency and perceived service quality. Data were collected by mapping patient processes in detail and surveying patients in two CDUs at a university hospital (n = 308). A univariate model was used to investigate the effect of these factors on patient throughput time, and perceived service quality was examined with multiple linear regression. Taking blood samples on Day -1 decreases patient throughput time and increases the perceived service quality by improving the patient's perception of technical expertise and the outcome. This has a globally positive effect on patients' perceived service quality. Dose banding affected neither patient throughput time nor perceived service quality. Taking the pretreatment blood sample on Day -1 can be considered an important process design characteristic, as it increases both efficiency and service quality. PMID- 30284338 TI - Percutaneous Peripheral Nerve Stimulation (PNS) for the Treatment of Chronic Low Back Pain Provides Sustained Relief. AB - OBJECTIVES: The objective of this study was to evaluate the use of percutaneous peripheral nerve stimulation (PNS) for the treatment of chronic low back pain (LBP). Percutaneous PNS offers the potential to provide an effective neuromodulation therapy using a system and fine-wire leads designed specifically for percutaneous use with history of an excellent safety profile. MATERIALS AND METHODS: Subjects with chronic axial LBP received percutaneous PNS leads targeting the medial branch of the dorsal ramus in the region of LBP. Lead placement was guided using ultrasound and confirmed by selective activation of the lumbar multifidus and patient-reported sensations. The percutaneous fine-wire leads remained in place for the 30-day therapy. RESULTS: A majority of subjects reported statistically and clinically significant reductions in both average pain intensity (BPI-5) and worst pain intensity (BPI-3) scores with PNS treatment, which continued long term at the four-month follow-up visit. Subject-reported reductions in pain intensity were substantiated by concomitant and sustained reductions in analgesic medication usage. Subjects also reported clinically significant reductions in patient-centric outcomes of disability (Oswestry Disability Index), pain interference (BPI-9), and patient global impression of change (PGIC). CONCLUSIONS: This work demonstrates the potential value of percutaneous PNS for the treatment of chronic LBP. Improvements in pain, medication, and patient-centric outcomes, which were sustained long term after the removal of PNS leads, demonstrate the significance of this innovative approach to treat chronic LBP. PMID- 30284340 TI - Chronic stress and intestinal permeability: Lubiprostone regulates glucocorticoid receptor-mediated changes in colon epithelial tight junction proteins, barrier function, and visceral pain in the rodent and human. AB - BACKGROUND: Chronic psychological stress is associated with increased intestinal epithelial permeability and visceral hyperalgesia. Lubiprostone, an agonist for chloride channel-2, promotes secretion and accelerates restoration of injury induced epithelial barrier dysfunction. The mechanisms underlying how lubiprostone regulates colon epithelial barrier function and visceral hyperalgesia in chronic stress remain unknown. METHODS: Male rats were subjected to water avoidance stress for 10 consecutive days. Lubiprostone was administered daily during the stress phase. Visceromotor response to colorectal distension was measured. Human colon crypts and cell lines were treated with cortisol and lubiprostone. The transepithelial electrical resistance and FITC-dextran permeability were assayed. Chromatin immunoprecipitation was conducted to assess glucocorticoid receptor binding at tight junction gene promoters. KEY RESULTS: Lubiprostone significantly decreased chronic stress-induced visceral hyperalgesia in the rat (P < 0.05; n = 6). WA stress decreased occludin and claudin-1 and increased claudin-2 in rat colon crypts, which was prevented by lubiprostone. Cortisol treatment induced similar alterations of tight junction protein expression in Caco-2/BBE cells (P < 0.05) and significantly changed paracellular permeability in monolayers (P < 0.01). These changes were blocked by lubiprostone. Glucocorticoid receptor and its binding at occludin promoter region were decreased in cortisol-treated cells and human colon crypts, which was largely reversed by lubiprostone. In rat colonic cells, glucocorticoid receptor and its co-chaperone proteins were down-regulated after corticosterone treatment and lubiprostone reversed these changes. CONCLUSIONS & INFERENCES: Lubiprostone preferentially prevents chronic stress-induced alterations of intestinal epithelial tight junctions, barrier function, and visceral hyperalgesia that was associated with modulation of glucocorticoid receptor expression and function. PMID- 30284339 TI - Novel cinnamic acid-tryptamine hybrids as potent butyrylcholinesterase inhibitors: Synthesis, biological evaluation, and docking study. AB - A novel series of cinnamic acid-tryptamine hybrids was designed, synthesized, and evaluated as cholinesterase inhibitors. Anticholinesterase assays showed that all of the synthesized compounds displayed a clearly selective inhibition of butyrylcholinesterase (BChE), but only a moderate inhibitory effect toward acetylcholinesterase (AChE) was detected. Among these cinnamic acid-tryptamine hybrids, compound 7d was found to be the most potent inhibitor of BChE with an IC50 value of 0.55 +/- 0.04 MUM. This compound showed a 14-fold higher inhibitory potency than the standard drug donepezil (IC50 = 7.79 +/- 0.81 MUM) and inhibited BChE through a mixed-type inhibition mode. Moreover, a docking study revealed that compound 7d binds to both the catalytic anionic site (CAS) and the peripheral anionic site (PAS) of BChE. Also, compound 7d was evaluated against beta-secretase, which exhibited low activity (inhibition percentage: 38%).

AB - The successful incorporation of a thermally fragile imidazolium moiety into a covalent triazine framework resulted in a heterogeneous organocatalyst active in carbene-catalyzed umpolung reaction. The structural integrity of the imidazolium moiety was confirmed by combining solid-state NMR and XPS experiments. PMID- 30284342 TI - Copulatory mechanism and functional morphology of genitalia and anal horn of the scorpionfly Cerapanorpa dubia (Mecoptera: Panorpidae). AB - The scorpionfly genus Cerapanorpa is characterized by the male possessing a single finger-like anal horn on the posterior portion of tergite VI. However, the functional morphology of this anal horn and the genitalia have not been studied to date. Herein, we investigated the functional morphology of the genitalia and the nongenital structures of the scorpionfly Cerapanorpa dubia by observing the mating process and dissecting the freeze-fixated pairs in copula to reveal the copulatory mechanism. The male C. dubia provides a solid salivary mass to the female as a nuptial gift prior to copulation. When the female starts to feed on the gift, the male uses his notal organ and complex genital structures to control the closest wing and genitalia of the female to establish a V-shaped mating position. In the maintenance phase of copulation, the male uses his anal horn in cooperation with the basally-constricted abdominal segment VII to clamp female abdominal segment VIII. The male hypovalves grasp female cerci, and move up and down rhythmically. The paired parameres clasp both sides of female tergite IX. The basal processes on male gonostyli grip the pleural membranes of the female genital chamber. In the sperm transfer phase, the male aedeagus directly couples with the female medigynium to transmit sperm by connecting his phallotreme to the female's copulatory pore. The evolution of the male complex grasping structures in Panorpidae is also briefly discussed. PMID- 30284344 TI - Tuning the Phase Transition from UCST-Type to LCST-Type by Composition Variation of Polymethacrylamide Polymers. AB - Polymethacrylamide copolymers with hydrophobic N-substituted acrylamides, such as N-cyclohexylacrylamide and N-tert-butylacrylamide, are rare examples of polymers showing composition-dependent thermoresponsive behavior in water. They show unexpected behavior different from the conventional copolymers of a thermoresponsive polymer with hydrophobic comonomers. On increasing the amount of the hydrophobic comonomer in the polymer, there is a change from UCST-type phase behavior to complete solubility, followed by compositions showing LCST-type transition and insolubility in water (U-S-L-I-type change). At 50 mol% of less hydrophobic N-tert-butyl acrylamide (logP 0.87) in contrast to ~25 mol% of N cyclohexylacrylamide (logP 1.51), the broad UCST-type transition of polymethacrylamide is turned to LCST-type transitions with very narrow hysteresis in water and PBS buffer. The use of H-bond and water-structure breaker showed the role of H-bonding and hydrophobic interactions in phase transitions of UCST-type and LCST-type, respectively. This work is an important add-on to the infant field of nonionic polymers of UCST-type. PMID- 30284343 TI - Improving the delivery of physical activity services in lung cancer: A qualitative representation of the patient's perspective. AB - OBJECTIVE: To explore patient experiences of, and preferences for, physical activity after a lung cancer diagnosis. METHODS: This was a qualitative study involving seven patients who had been treated for lung cancer within the previous 2 years. Participants attended a focus group interview. Conventional content analysis methodology was used to analyse the text by two independent researchers. RESULTS: Eight major themes emerged from the data. These were as follows: the influence of past lifestyle and chronic disease; the perceived benefits of physical activity; using physical activity to facilitate return to activities of daily living; the impact of symptoms, capacity and motivation; family and peer support; access to services; health professionals; and enjoyment of different types of physical activity. Patients suggested several factors that could improve their healthcare experience. These include access to exercise professionals particularly after cancer treatment; access to information about physical activity in different formats; supervision from health professionals and peer support; and use of behaviour change strategies to achieve sustainable increases in physical activity. CONCLUSION: Our results should be considered in the improvement of lung cancer care pathways as we strive to implement physical activity services into routine clinical care. PMID- 30284345 TI - Array-based profiling of the lymphoma cell DNA methylome does not unequivocally distinguish primary lymphomas of the central nervous system from non-CNS diffuse large B-cell lymphomas. AB - Primary lymphomas of the central nervous system (PCNSL) are diffuse large B-cell lymphomas (DLBCLs) confined to the central nervous system (CNS). We here performed array-based DNA methylation analyses of 26 PCNSL and 78 DLBCL and validated our findings in an independent dataset. We identified 2847 CpGs differentially methylated between PCNSL and non-CNS-DLBCL. Neither a supervised analysis using these CpGs nor application of 3 CpG classifiers selected for class separation unambiguously separated PCNSL from non-CNS-DLBCL. Remarkably, 6/78 non CNS-DLBCL consistently segregated with PCNSL, which displayed molecular features typical for PCNSL. Our findings suggest that a subset of non-CNS-DLBCL exists which molecularly resembles PCNSL.

PMID- 30284347 TI - Effect of Microscopic Susceptibility Gradients on Chemical-Shift-Based Fat Fraction Quantification in Supraclavicular Fat. AB - BACKGROUND: Susceptibility differences between fat and water can cause changes in the water-fat frequency separation that can negatively affect the accuracy of fat fraction techniques. This may be especially relevant for brown adipose tissue, as MRI fat fraction techniques have been proposed for its detection. PURPOSE: To assess the effect of microscopic magnetic susceptibility gradients on the water fat frequency separation and its impact on chemical-shift-based fat fraction quantification techniques in the supraclavicular fat, where brown adipose tissue is commonly found in humans. STUDY TYPE: Prospective. POPULATION/SUBJECTS/PHANTOM/SPECIMEN/ANIMAL MODEL: Subjects: 11 healthy volunteers, mean age of 26 and mean BMI of 23, three overweight volunteers, mean age of 38 and mean BMI of 33. Phantoms: bovine phantom and intralipid fat emulsion. Simulations: various water-fat distributions. FIELD STRENGTH/SEQUENCE: Six-echo gradient echo chemical-shift-encoded sequence at 3T. ASSESSMENT: Fat fraction values as obtained from a water-fat spectral model accounting for susceptibility-induced water-fat frequency variations were directly compared to traditional spectral models that assume constant water-fat frequency separation. STATISTICAL TESTS: Two-tail t-tests were used for significance testing (p < 0.05.) A Bayesian Information Criterion difference of 6 between fits was taken as strong evidence of an improved model. RESULTS: Phantom experiments and simulation results showed variations of the water-fat frequency separation up to 0.4 ppm and 0.6 ppm, respectively. In the supraclavicular area, the water-fat frequency separation produced by magnetic susceptibility gradients varied by as much as +/ 0.4 ppm, with a mean of 0.08 +/- 0.14 ppm, producing a mean difference in fat fraction of -1.26 +/- 5.26%. DATA CONCLUSION: In the supraclavicular fat depot, microscopic susceptibility gradients that exist within a voxel between water and fat compartments can produce variations in the water-fat frequency separation. These variations may produce fat fraction quantification errors of 5% when a spectral model with a fixed water-fat frequency separation is applied, which could impact MR brown fat techniques. LEVEL OF EVIDENCE: 1 Technical Efficacy: Stage 1 J. Magn. Reson. Imaging 2018. PMID- 30284348 TI - Ethnic variations in the childhood prevalence of Hirschsprung disease in New Zealand. AB - BACKGROUND: Epidemiological studies have suggested that there may be ethnic variations in the prevalence of Hirschsprung disease (HD) but no study has systematically investigated this issue or potential ethnic variations in the extent of aganglionosis in HD. This study aimed to investigate this in a childhood population in New Zealand. METHODS: A multicentre national retrospective review was undertaken of all newly diagnosed cases of HD at each of the four paediatric surgical centres in New Zealand over a 16-year period (January 2000 to December 2015). Original histological, radiological and operative reports were obtained and analysed. Self-identified ethnicity was recorded from admission documents. Birth statistics were obtained from Statistics New Zealand. RESULTS: A total of 246 cases of HD were identified. The prevalence of HD was 1:3790 live births for European, 1:6610 among Maori, 1:1834 among Pacific Peoples, 1:3847 among Asian and 1:5694 among Middle Eastern. The prevalence of HD was statistically significantly greater in Pacific Peoples (P < 0.0005). The proportion of children with long-segment HD was also significantly greater in Pacific and Asian populations than others (P = 0.04). These findings were not due to differences in the proportion of familial cases of HD among the different populations. CONCLUSIONS: The prevalence and phenotype of HD varies significantly between different ethnic groups within New Zealand. This may well be related to variations in the frequencies of HD-associated gene mutations within these populations. PMID- 30284350 TI - Safety, Feasibility, and Efficacy of Transcutaneous Tibial Nerve Stimulation in Acute Spinal Cord Injury Neurogenic Bladder: A Randomized Control Pilot Trial. AB - OBJECTIVES: We investigated whether transcutaneous tibial nerve stimulation (TTNS) in acute spinal cord injury was safe and feasible, and could achieve neuromodulation and improve cystometrogram parameters during acute inpatient rehabilitation. MATERIALS AND METHODS: Participants were consecutive acute traumatic spinal cord injury patients admitted for acute inpatient rehabilitation, randomized to a 2-week trial of TTNS v sham stimulation. Primary outcomes were safety and feasibility of TTNS and secondary outcomes were bladder measures based on pre- and post-TTNS cystometrogram by group and within groups, including bladder capacity, detrusor hyperreflexia, pressures, and detrusor sphincter dyssynergia, as well as filling sensations and desire to void. The principle investigator and subjects were blinded to treatment allocation. RESULTS: A total of 19 subjects consented to the study and completed the stimulation protocol. Morbidity was similar between groups and compliance was 100% to the TTNS protocol. Based on a lack of rehabilitation interruptions and comments from staff, TTNS was feasible. Post-cystometrogram parameters were significant for lower volumes until sensation in the control group and prolonged volumes until sensation in the TTNS group. The control group had significant changes of increased detrusor-sphincter dyssynergia and decreased bladder capacity. This was not significantly changed in the TTNS group. CONCLUSIONS: TTNS is a safe and feasible modality that can be performed during inpatient rehabilitation of acute traumatic spinal cord injury. Bladder capacity and episodes of detrusor-sphincter dyssynergia significantly worsened in the control group and did not significantly change in the TTNS group, suggesting that TTNS can alter the course of neurogenic bladder via neuromodulation. PMID- 30284349 TI - Cardiovascular safety of oral semaglutide in patients with type 2 diabetes: Rationale, design and patient baseline characteristics for the PIONEER 6 trial. AB - AIMS: To assess the cardiovascular (CV) safety of oral semaglutide, the first tablet formulation of a glucagon-like peptide-1 receptor agonist. MATERIALS AND METHODS: PIONEER 6 is a multinational, randomized, placebo-controlled, double blind trial in patients with type 2 diabetes at high risk of CV events (defined as being aged >=50 years and having established CV disease [CVD] or moderate [stage 3] chronic kidney disease [CKD], or being aged >=60 years with >=1 other CV risk factor). Patients were randomized to once-daily oral semaglutide (up to 14 mg) or placebo added to standard of care. The primary composite endpoint is time to first occurrence of CV death or non-fatal myocardial infarction or non fatal stroke. The primary hypothesis was to exclude an excess in CV risk with oral semaglutide by assessing non-inferiority versus placebo for the primary endpoint (non-inferiority margin of 1.8 for the upper boundary of the 95% confidence interval of the hazard ratio). PIONEER 6 is event-driven, with follow up continuing until accrual of at least 122 primary outcome events. There is no pre-defined minimal duration. RESULTS: Overall, 3183 patients have been enrolled (mean age 66.1 years, 31.6% females) in 214 sites across 21 countries. At baseline, the mean duration of diabetes was 14.9 years, mean glycated haemoglobin concentration was 66 mmol/mol (8.2%), and 84.6% of patients had established CVD/moderate CKD. CONCLUSIONS: PIONEER 6 will provide evidence regarding the CV safety of oral semaglutide in patients with type 2 diabetes and high CV risk.

PMID- 30284352 TI - Effectiveness of high-intensity interval training combined with resistance training versus continuous moderate-intensity training combined with resistance training in patients with type 2 diabetes: A one-year randomized controlled trial. AB - AIMS: To evaluate the impact of one-year high intensity interval training (HIIT) combined with resistance training (RT) vs continuous moderate intensity training (MCT) combined with RT on glycaemic control, body composition and cardiorespiratory fitness (CRF) in patients with type 2 diabetes. MATERIALS AND METHODS: A randomized controlled trial included 96 participants with type 2 diabetes for a one-year supervised exercise intervention with three groups: Control, HIIT with RT and MCT with RT). The control group received standard counseling regarding general PA guidelines, with no structured exercise sessions. The main outcome variable was HbA1c (%). Secondary outcomes were other glycaemic variables, body composition, anthropometry measurements, CRF and enjoyment of exercise. Generalized estimating equations (GEE) were used to model outcomes. RESULTS: Among the 96 participants enrolled in the intervention, 80 were randomized, with a mean (SD) age of 58.5 years (7.7) and a mean HbA1c of 7.2% (1.6). After adjusting the model for sex and total moderate-to-vigorous physical activity (MVPA), we found that both the MCT with RT (beta, 0.003; P, 0.921) and the HIIT with RT (beta, 0.025; P, 0.385) groups had no effect on HbA1c. A favourable effect was observed in the MCT with RT group, with a reduction in whole body fat index (beta, -0.062; P, 0.022), android fat index (beta, -0.010; P, 0.010) and gynoid fat index (beta, -0.013; P, 0.014). Additionally, CRF increased during the intervention, but only in the MCT with RT group (beta, 0.185; P, 0.019). CONCLUSIONS: The results from this study suggest that there was no effect of either MCT with RT or HIIT with RT on glycaemic control in individuals with type 2 diabetes. However, the combination of MCT and RT improved body composition and CRF following a one-year intervention. PMID- 30284353 TI - Thai version of the Functional Rating Index for patients with back and neck pain: Part II responsiveness and head-to-head comparisons. AB - OBJECTIVES: To examine responsiveness and estimate minimal clinically important difference (MCID) of the Thai version of Functional Rating Index (Thai FRI) and examine head-to-head comparisons of the Thai FRI and other questionnaires. METHODS: This study related to validation of a questionnaire and head-to-head comparisons. Patients with low back pain (LBP) completed the Thai FRI, Roland Morris (RM), modified Oswestry, and multilevel RM disability questionnaires. Patients with neck pain (NP) completed the Thai FRI and Neck Disability Index at the first visit and 2-week follow-up. Patients and therapists rated Global Perceived Effect Scales (GPES). Effect size (ES), standardized response mean (SRM), correlations between the GPES with changes in questionnaire scores, and area under receiver operating characteristic curve (AUC) were calculated. The MCID was also estimated. RESULTS: Eighty-four patients with LBP and 52 patients with NP completed the Thai FRI. ES = 1.34 for LBP; 1.28 for NP, SRM = 1.32 for LBP; 1.20 for NP, correlation = 0.49 for LBP; 0.38 for NP, AUC = 0.83 for both groups. MCID = 11.5 for LBP; 12.5 FRI points for NP. CONCLUSION: The Thai FRI demonstrated responsiveness with large ES. Its MCID ranged from 11.5 to 12.5 FRI points. The Thai FRI had comparable responsiveness to other questionnaires and was appropriate for use in the patients with back and/or neck pain. PMID- 30284354 TI - The use of rituximab in treatment of epidermolysis bullosa acquisita: Three new cases and a review of the literature. AB - Epidermolysis bullosa acquisita (EBA) is a rare, subepidermal blistering disease affecting the skin and mucous membranes that often remains refractory to standard immunosuppressive therapy. We present three original cases and a review of the literature of 20 cases of refractory EBA treated with rituximab as monotherapy or in combination with other agents. Complete control (with or without therapy) and remission were seen in 56% of patients treated with rituximab monotherapy and 75% of patients treated with rituximab and immunoadsorption (IA). We conclude EBA refractory to standard immunosuppressive therapy may show a more favorable long term response to the addition of rituximab; and rituximab in combination with intravenous immunoglobulin or IA may provide utility in terminating acute disease. Additional data are needed to evaluate the safety and long-term outcomes of rituximab-based treatment. PMID- 30284355 TI - Prevalence of toxoplasmosis and its association with dementia in older adults in Central Africa: a result from the EPIDEMCA programme. AB - OBJECTIVE: We aimed at estimating the seroprevalence of Toxoplasma gondii (T. gondii) infection in older adults living in Central Africa and investigating its association with dementia using data from the Epidemiology of Dementia in Central Africa (EPIDEMCA) programme. METHODS: A cross-sectional multicentre population based study was carried out among participants aged 73 (+/-7) years on average, living in rural and urban areas of the Central African Republic and the Republic of Congo between November 2011 and December 2012. Blood samples were collected from each consenting participant. The detection of anti-T. gondii immunoglobulin G antibodies was performed in 2014 in France using a commercially available ELISA kit. Participants were interviewed using a standardised questionnaire including sociodemographic characteristics. DSM-IV criteria were required for a diagnosis of dementia. Multivariate binary logistic regression models were used to assess the association between toxoplasmosis infection and dementia. RESULTS: Among 1662 participants, the seroprevalence of toxoplasmosis was 63.0% (95% confidence interval (CI): 60.7-65.3) overall, 66.6% (95%CI: 63.4-69.8) in Central African Republic and 59.4% (95%CI: 56.1-62.7) in the Republic of Congo. In multivariate analyses, toxoplasmosis status was significantly associated with increasing age (P = 0.006), Republic of Congo (P = 0.002), urban area (P = 0.001) and previous occupation (P = 0.002). No associations between dementia and toxoplasmosis status or anti-T. gondii IgG titres were found. CONCLUSION: Toxoplasma gondii infection was not associated with dementia among older adults in Central Africa. Our findings are consistent with previous studies and add to the knowledge on the relationship between T. gondii infection and neurological disorders. PMID- 30284356 TI - Anterior, frontal congenital triangular alopecia, redundancy in therapy without improvement. AB - Congenital triangular alopecia (CTA) is a benign noncicatricial localized pattern of hair loss with unknown etiology. Although referred to as "congenital," CTA may develop in adulthood. It is believed that many cases of CTA are never diagnosed or are misdiagnosed; causing the incidence to be underestimated. The present study evaluates a case of 20-year-old woman presenting with a single circular to oval area of hair-loss in the mid-frontal region of her scalp. To date, about 170 cases of CTA have been reported and we present the first case in which the alopecic patch is located in the mid-frontal region of the scalp. We present this case not only to challenge the preconceived notion that all CTAs are frontotemporal, but also to inform other practitioners about this rare condition and prevent redundant medical treatment. PMID- 30284357 TI - Isomerism of the Aniline Trimer. AB - Weaker intermolecular forces expand the isomerization alternatives for molecular aggregation, as observed for the prototype models of the aniline trimer (An3 ) and the monohydrated aniline dimer (An2 -W) when compared to the phenol trimer. In this experiment the aniline clusters were generated in a jet-cooled expansion and probed using broadband (chirped-pulsed) microwave spectroscopy. Three isomers of the aniline trimer and two isomers of the hydrated dimer were detected and characterized in the rotational spectrum. In the homotrimer the weak N-H???N hydrogen bonds are assisted by subtle combinations of N-H???pi and C-H???pi interactions, producing several competing low-lying ring species in the gas phase. One of the aniline trimers is a symmetric top, topologically equivalent to the only observed phenol trimer. Conversely, addition of a water molecule to the aniline dimer introduces a leading O-H???N interaction, making water to behave as dominant hydrogen-bond pivot between the two aniline molecules. This combination of weak intermolecular interactions critically tests the performance of dispersion-corrected or parametrized density-functional methods. Evaluation of the B3LYP-D3(BJ) and M06-2X methods revealed deficiencies of the Truhlar functional to reproduce the experimental rotational data. PMID- 30284359 TI - Composition Tailoring via N and S Co-doping and Structure Tuning by Constructing Hierarchical Pores: Metal-Free Catalysts for High-Performance Electrochemical Reduction of CO2. AB - A facile route to scalable production of N and S co-doped, hierarchically porous carbon nanofiber (NSHCF) membranes (ca. 400 cm2 membrane in a single process) is reported. As-synthesized NSHCF membranes are flexible and free-standing, allowing their direct use as cathodes for efficient electrochemical CO2 reduction reaction (CO2 RR). Notably, CO with 94 % Faradaic efficiency and -103 mA cm-2 current density are readily achieved with only about 1.2 mg catalyst loading, which are among the best results ever obtained by metal-free CO2 RR catalysts. On the basis of control experiments and DFT calculations, such outstanding CO Faradaic efficiency can be attributed to the co-doped pyridinic N and carbon-bonded S atoms, which effectively decrease the Gibbs free energy of key *COOH intermediate. Furthermore, hierarchically porous structures of NSHCF membranes impart a much higher density of accessible active sites for CO2 RR, leading to the ultra-high current density.

PMID- 30284358 TI - Magnetic Resonance Elastography in the Assessment of Acute Effects of Kinesio Taping on Lumbar Paraspinal Muscles. AB - BACKGROUND: Kinesio tape (KT) is an elastic therapeutic tape used for treating sports-related injuries and a number of other disorders. To date, the objective evidence to link pathophysiological effects and actual reactions triggered by KT is limited. PURPOSE: To explore the effect of KT on the lumbar paraspinal muscles by magnetic resonance (MR) elastography. STUDY TYPE: Prospective observational study. POPULATION: Sixty-six asymptomatic volunteers with 31 women and 35 men. FIELD STRENGTH/SEQUENCE: 3.0T MRI and elastography with vibration frequency of 120 Hz. ASSESSMENT: The 5-cm-width KT with full tension was placed on a single side of the lumbar paraspinal muscle. The taping side and adhering direction were randomly decided. Two rectangular regions of interest (ROIs) of 5- and 2.5-cm width were positioned at the bilateral paraspinal regions from the L2 to L4 level on the confidence map of MR elastography before and after KT taping. The mean shear stiffness values of the ROIs at the superficial, middle, and deep depths were recorded; then the differences between the taping and reference sides were calculated. STATISTICAL TESTS: Paired t-test and Pearson correlations were used to evaluate the stiffness changes after KT application and intraoperator errors of the stiffness measures on the reference side, respectively. RESULTS: A significant decrease in the muscle stiffness value between taping and reference sides (-0.71 kPa +/- 0.60 with KT and -0.25 kPa +/- 0.78 without KT, P < 0.0001 for 5-cm ROI; -0.67 kPa +/- 1.12 with KT and -0.16 kPa +/- 1.17 without KT, P = 0.0004 for 2.5-cm ROI) was found in the superficial depth, but no significant differences in the middle and deep depths (P = 0.25 and P = 0.79 for 5-cm ROI; P = 0.09 and P = 0.67 for 2.5-cm ROI, respectively). There were no significant differences of muscle stiffness differences between gender (P = 0.11 for superficial, P = 0.37 for middle, P = 0.78 for deep) and taping direction (P = 0.18 for superficial, P = 0.13 for middle, P = 0.15 for deep). DATA CONCLUSION: Our results demonstrate that KT can reduce the MR elastography-derived shear stiffness in the superficial depth of paraspinal muscles.

AB - PURPOSE: To report the quality of life and visual functioning in uveal melanoma patients treated with enucleation or fractionated stereotactic radiation therapy (fSRT). METHODS: Uveal melanoma (UM) patients treated with fSRT (n = 65) or enucleation (n = 48) participated in this prospective study. Questionnaires to measure anxiety (State-Trait Anxiety Inventory), subjective distress (Impact of Event Scale) and quality of life (EORTC-QLQ-C30 and National Eye Institute Visual Function Questionnaire (VFQ-25)) were obtained before treatment and 2, 6, 12, 24, 36 and 48 months after treatment. RESULTS: Less peripheral vision was observed until 3 years (p = 0.026) posttreatment in enucleated patients compared to irradiated patients. From 2 months until 3 years posttreatment irradiated patients increase in role functioning-score (p = 0.005), while enucleated patients decrease in score (p = 0.012). Regardless of their treatment, for all patients we measured a reduction in physical functioning (p = 0.035), insomnia (p < 0.001) and in state anxiety from pretreatment until 2 years posttreatment (p < 0.001). An increase in pain overall (p = 0.023) and in emotional functioning is observed 1 year posttreatment (p < 0.001). At baseline, patients with metastases (independent of their treatment) have more subjective distress (p = 0.037) than patients without metastases. The mean 'global health score' overall, without effect of time, was 76.4 (SD: 13.6). CONCLUSION: Enucleated patients had more difficulty working or performing household tasks 2 months posttreatment compared to irradiated patients. Enucleated patients had diminished peripheral vision until 3 years compared to irradiated patients. Overall quality of life is not significantly different between both treatment groups. PMID- 30284370 TI - Evaluation of offline adaptive planning techniques in image-guided brachytherapy of cervical cancer. AB - Modern three-dimensional image-guided intracavitary high dose rate (HDR) brachytherapy is often used in combination with external beam radiotherapy (EBRT) to manage cervical cancer. Intrafraction motion of critical organs relative to the HDR applicator in the time between the planning CT and treatment delivery can cause marked deviations between the planned and delivered doses. This study examines offline adaptive planning techniques that may reduce intrafraction uncertainties by shortening the time between the planning CT and treatment delivery. Eight patients who received EBRT followed by HDR boosts were retrospectively reviewed. A CT scan was obtained for each insertion. Four strategies were simulated: (A) plans based on the current treatment day CT; (B) plans based on the first fraction CT; (C) plans based on the CT from the immediately preceding fraction; (D) plans based on the closest anatomically matched previous CT, using all prior plans as a library. Strategies B, C, and D allow plans to be created prior to the treatment day insertion, and then rapidly compared with the new CT. Equivalent doses in 2 Gy for combined EBRT and HDR were compared with online adaptive plans (strategy A) at D90 and D98 for the high-risk CTV (HR-CTV), and D2 cc for the bladder, rectum, sigmoid, and bowel. Compared to strategy A, D90 deviations for the HR-CTV were -0.5 +/- 2.8 Gy, -0.9 +/- 1.0 Gy, and -0.7 +/- 1.0 Gy for Strategies B, C, and D, respectively. D2 cc changes for rectum were 2.7 +/- 5.6 Gy, 0.6 +/- 1.7 Gy, and 1.1 +/- 2.4 Gy for Strategies B, C, and D. With the exception of one patient using strategy B, no notable variations for bladder, sigmoid, and bowel were found. Offline adaptive planning techniques can shorten time between CT and treatment delivery from hours to minutes, with minimal loss of dosimetric accuracy, greatly reducing the chance of intrafraction motion. PMID- 30284371 TI - The Longitudinal Danish High Myopia Study, Cohort 1948: at age 66 years visual ability is only occasionally affected by visual field defects. AB - PURPOSE: A descriptive study on visual fields, as part of a 50-year follow-up of high myopia in an unselected cohort-based Danish sample, now aged 66 years. METHODS: In a Copenhagen 1948 birth cohort (n = 9243), 39 individuals aged 14 years were identified with myopia of at least -6 D, and with regular clinical follow-ups since then. In 2002 (n = 34, age 54 years) and 2008 (n = 32, age 60), the individual ambulatory visual field was outlined by kinetic Goldmann large object perimetry (IV or V,4e). At age 66 years, 28 attended for the 2014-2015 follow-up, at which smaller Goldmann objects (II and I,4e) were added, further to identify relative defects. RESULTS: Repeated large object perimetry disclosed statistically significant general peripheral narrowing over the 12-13-year test period, though slight and without practical implications. Two new cases showing absolute defects were however added to the three already known. The addition of small Goldmann objects disclosed relative defects in another eight participants, in some to suggest a refraction-related pattern (fundus ectasia; uncorrected high myopia). However, comparing eyes with and without defects, statistical importance could not be attached to the degree of myopia, fundus ectasia or optic disc morphology (chi2 , n.s.). CONCLUSION: (i) Serial large object Goldmann isopters over the 'senior' decade up to age 66 demonstrated a slight general peripheral narrowing by age of visual fields in high myopia. (ii) Overall 42% of the participants had absolute or relative defects (in 5 and 8, respectively), however, without socio-visual consequences when binocular. (iii) Visual field loss by age still appears a minor issue in clinically unselected high myopia. PMID- 30284372 TI - Laser Direct Writing of Heteroatom (N and S)-Doped Graphene from a Polybenzimidazole Ink Donor on Polyethylene Terephthalate Polymer and Glass Substrates. AB - In this paper, for the first time, a laser direct writing technique is reported to form S- and N-doped graphene patterns on thin (0.3 mm thickness) polyethylene terephthalate (PET) and glass substrates from a specially formulated organic polybenzimidazole (PBI) ink, without thermally affecting the substrates and without the need for a metallic precursor. Unlike standard graphene ink printing, postcuring at high temperatures is not needed here, thus avoiding potential substrate distortion and damages. A UV laser beam of 355 nm wavelength is used to generate photochemical reactions to break the C?S bond (2.8 eV) from dimethyl sulfoxide (DMSO, a component of the PBI ink) and the C?N bond (3.14 eV) of PBI and form N- and S-doped graphene on the substrates. The sheet resistance of the laser-induced graphene is as low as 12 Omega sq-1 on PET, matching that of indium tin oxide (ITO). The laser-written doped graphene shows hydrophilic characteristics, unlike pristine graphene. The S- and N-doped graphene allows the tailoring of bandgaps and thus controlling electrical and chemical properties. The optical transparency of the written graphene is below 10% which could be improved in the future. Potential applications include printing of flexible circuits and sensors, and smart wearables.

AB - Recent climate warming has affected some life-history traits of insects, including voltinism and body size. The magnitude of changes in these traits may differ latitudinally within a species because of the differing lengths of season available for growth. The present study aims to estimate the change in voltinism of the lawn ground cricket, Polionemobius mikado (Shiraki) (Orthoptera: Trigonidiidae), over the last four decades by comparing the body size between adults collected from a wide range of latitudes in Japan in recent years (2015 2017) and those collected four decades ago (1969-1976). The body size of adults collected in recent years showed a latitudinal saw-tooth cline, in the same way as body size did four decades ago, and the cline shifted northward over the last four decades: In 2015-2017, the body size decreased slightly with increasing latitude from 31 degrees N to 36 degrees N, and then increased to 40 degrees N, and again decreased from 40 degrees N to 44 degrees N. Comparison of the body size between recent years and four decades ago revealed that the body size has decreased significantly at the middle latitudes (36-40 degrees N), suggesting that the proportion of smaller bivoltine individuals there has increased over the last four decades. The sum of effective temperatures for postdiapause embryonic development at around 36 degrees N in recent years was comparable to that at 31 35 degrees N four decades ago, at which P. mikado populations were bivoltine. Taken together, these findings suggested that the latitudinal range suitable for the bivoltine life cycle of P. mikado has expanded northward over the last four decades because of climate warming. This is the first report that shows that a decrease in body size can be caused by climate warming via an increase in voltinism. PMID- 30284376 TI - Automated quantification of reference levels in liver and mediastinal blood pool for the Deauville therapy response classification using FDG-PET/CT in Hodgkin and non-Hodgkin lymphomas. AB - BACKGROUND: 18F-FDG-PET/CT has become a standard for assessing treatment response in patients with lymphoma. A subjective interpretation of the scan based on the Deauville 5-point scale has been widely adopted. However, inter-observer variability due to the subjectivity of the interpretation is a limitation. Our main goal is to develop an objective and automated method for evaluating response. The first step is to develop and validate an artificial intelligence (AI)-based method, for the automated quantification of reference levels in the liver and mediastinal blood pool in patients with lymphoma. METHODS: The AI-based method was trained to segment the liver and the mediastinal blood pool in CT images from 80 lymphoma patients, who had undergone 18F-FDG-PET/CT, and apply this to a validation group of six lymphoma patients. CT segmentations were transferred to the PET images to obtain automatic standardized uptake values (SUV). The AI-based analysis was compared to corresponding manual segmentations performed by two radiologists. RESULTS: The mean difference for the comparison between the AI-based liver SUV quantifications and those of the two radiologists in the validation group was 0.02 and 0.02, respectively, and 0.02 and 0.02 for mediastinal blood pool respectively. CONCLUSIONS: An AI-based method for the automated quantification of reference levels in the liver and mediastinal blood pool shows good agreement with results obtained by experienced radiologists who had manually segmented the CT images. This is a first, promising step towards objective treatment response evaluation in patients with lymphoma based on 18F FDG-PET/CT.

PMID- 30284378 TI - Use of a commercial ion chamber detector array for the measurement of high spatial-resolution photon beam profiles. AB - Linear accelerator (linac) commissioning and quality assurance measurements are time-consuming tasks that often require a water tank scanning system to acquire profile scans for full characterization of dosimetric beam properties. To increase efficiency, a method is demonstrated to acquire variable resolution, photon beam profile data using a commercially available ion chamber array (0.5 cm detector spacing). Field sizes of 2 * 2, 5 * 5, 10 * 10, and 15 * 15 cm2 were acquired at depths in solid water of dmax , 5 cm, and 10 cm; additionally, beam profiles for field sizes of 25 * 25 and 40 * 40 cm2 were acquired at 5 cm depth in solid water at x-ray energies of 6 and 23 MV. 1D composite profiles were generated by combining discrete point measurements made at multiple couch positions. The 1D composite profile dataset was evaluated against a commissioning dataset acquired with a 3D water tank scan system utilizing (a) 0.125 cc ion chamber for 5 * 5, 10 * 10, 15 * 15, 25 * 25, and 40 * 40 field sizes and (b) a solid state detector for 2 * 2 cm2 field size. The two datasets were compared to the gamma criteria at 1%/1 mm and 2%/2 mm tolerance. Almost all pass rates exceeded 95% at 2%/2 mm except for the 6 MV 2 * 2 cm2 field size at dmax . Pass rates at 1%/1 mm ranged from 51% to 99%, with an average pass rate of 82%. A fourfold reduction in MU was achieved for scans larger than 15 * 15 cm2 using this method compared to the water tank scans. Further, dynamic wedge measurements acquired with the ion chamber array showed reasonable agreement with the treatment planning system. This method opens up new possibilities for rapid acquisition of variable resolution 2D-3D dosimetric data mitigating the need for acquiring all scan data with in-water measurements. PMID- 30284379 TI - Correlation of peripapillary retinal nerve fibre layer thickness with visual acuity in paediatric patients affected by optic pathway glioma. AB - PURPOSE: To evaluate peripapillary retinal nerve fibre layer (RNFL) thickness, measured by spectral-domain optical coherence tomography (SD-OCT), as a surrogate of visual function in a population of paediatric patients affected by optic pathway glioma (OPG) associated with neurofibromatosis type 1 (NF1). METHODS: A total of 38 paediatric patients (66 eyes) affected by MRI-proven OPG were included. Each patient underwent complete ophthalmological examination, including age-appropriate visual acuity (VA) assessment and RNFL analysis by SD-OCT. Visual acuity was classified as normal or pathologic using age-based normative data. Visual acuity was correlated to mean RNFL thickness of the whole peripapillary area and of each single analyzed sector (nasal, superior, temporal, inferior). RESULTS: Visual acuity was normal in 43 (65%) and pathologic in 23 (35%) eyes. Mean parapapillary RNFL thickness of each analyzed sector was significantly lower in eyes with abnormal VA (p < 0.05). The best balanced cut-off value of global RNFL thickness allowing to discriminate between eyes with normal and pathologic VA was 76.25 MUm (91%, 76%, 67% and 94% of sensitivity, specificity, positive and negative predicting value, respectively). Considering best balanced cut-off values of other analyzed RNFL sectors, the superior (p = 0.0029) and the inferior (p = 0.0024) sectors reached the higher sensitivity (87% and 87%, respectively) and specificity (81% and 79%, respectively). CONCLUSION: Retinal nerve fibre layer thickness is directly related to VA in children affected by NF1-related OPG, and should be considered as a potential surrogate marker of VA. Retinal nerve fibre layer thickness cut-off values can be used in paediatric patients to discriminate false-positive results obtained by VA measurement. PMID- 30284381 TI - Personalized risk-based screening for diabetic retinopathy: A multivariate approach versus the use of stratification rules. AB - AIMS: To evaluate our proposed multivariate approach to identify patients who will develop sight-threatening diabetic retinopathy (STDR) within a 1-year screen interval, and explore the impact of simple stratification rules on prediction. MATERIALS AND METHODS: A 7-year dataset (2009-2016) from people with diabetes (PWD) was analysed using a novel multivariate longitudinal discriminant approach. Level of diabetic retinopathy, assessed from routine digital screening photographs of both eyes, was jointly modelled using clinical data collected over time. Simple stratification rules based on retinopathy level were also applied and compared with the multivariate discriminant approach. RESULTS: Data from 13 103 PWD (49 520 screening episodes) were analysed. The multivariate approach accurately predicted whether patients developed STDR or not within 1 year from the time of prediction in 84.0% of patients (95% confidence interval [CI] 80.4 89.7), compared with 56.7% (95% CI 55.5-58.0) and 79.7% (95% CI 78.8-80.6) achieved by the two stratification rules. While the stratification rules detected up to 95.2% (95% CI 92.2-97.6) of the STDR cases (sensitivity) only 55.6% (95% CI 54.5-56.7) of patients who did not develop STDR were correctly identified (specificity), compared with 85.4% (95% CI 80.4-89.7%) and 84.0% (95% CI 80.7 87.6%), respectively, achieved by the multivariate risk model. CONCLUSIONS: Accurate prediction of progression to STDR in PWD can be achieved using a multivariate risk model whilst also maintaining desirable specificity. While simple stratification rules can achieve good levels of sensitivity, the present study indicates that their lower specificity (high false-positive rate) would therefore necessitate a greater frequency of eye examinations. PMID- 30284380 TI - Peritumoural adipose tissue pro-inflammatory cytokines are associated with tumoural growth factors in cancer cachexia patients. AB - BACKGROUND: Cancer cachexia (CC) is a multifactorial syndrome, often irreversible, that affects patients with cancer influenced, in part, by the inflammatory condition. Peritumoural adipose tissue produces adipokines and angiogenic, apoptotic, and growth factors; given the possible crosstalk between the peritumoural adipose tissue and tumour, these may play an important role in cancer biology and carcinogenesis. METHODS: The aim of this study was to evaluate the factors produced by peritumoural adipose tissue in a cohort of 16 colorectal cancer patients with either weight-stable cancer (WSC; n = 7) or CC (n = 9). The study was approved by the Ethics Research Committee (972.914). Samples of peritumoural adipose tissue were analysed for concentrations of TNF-alpha, IL 1beta, STAT-1, STAT-3, RANTES, IL-1Ra, IP-10, IL-15, MCP-1, IFN-alpha, GCSF, FADD, and TGF-beta. The cytokines and proteins were measured using Multiplex. Correlations between the proteins and cytokines were evaluated. RESULTS: TNF alpha, STAT-1, and FADD, a factor involved in apoptosis, were significantly higher in CC group than in the WSC group. In the peritumoural adipose tissue of the CC group, RANTES showed a significant positive correlation with IL-1Ra and IP 10 and a negative correlation with IFN-alpha; and GCSF showed significant negative correlations with IL-1Ra, IP-10, IL-15, and MCP-1 and a positive correlation with IFN-alpha. In the peritumoural adipose tissue of the WSC group, no significant correlations were detected between RANTES, GCSF, IL-3, FADD, and STAT-1 and the cytokines/chemokines analysed. CONCLUSIONS: These results indicated that inflammatory and tumorigenic pathways were altered in peritumoural adipose tissue in CC. Furthermore, inflammatory cytokines were correlated with growth factors in the peritumoural adipose tissue of cachectic patients, suggesting that inflammatory cytokines modulated the proliferative environment closely linked to the tumour.

PMID- 30284383 TI - Superior outcome of corneal collagen cross-linking using riboflavin with methylcellulose than riboflavin with dextran as the main supplement. AB - PURPOSE: To compare the effect of corneal collagen cross-linking (CXL) on progressive keratoconus using 0.1% riboflavin with either dextran or methylcellulose as the main supplement. METHODS: In a comparative case series, CXL was performed in 40 patients (40 eyes) using a riboflavin solution containing either dextran (dextran-riboflavin; n = 20) or methylcellulose (methylcellulose riboflavin; n = 20). Changes in central corneal thickness (CCT), Scheimpflug tomography, maximal keratometry reading (Kmax ), visual acuity (VA) and endothelial cell density (ECD) were recorded. Stromal changes one month after surgery were analysed using optical coherence tomography (OCT) and in vivo confocal microscopy (IVCM). RESULTS: The CCT was significantly higher in the methylcellulose-riboflavin group during the CXL procedure. The IVCM demarcation line depth was 274 +/- 80 (SD) MUm in the dextran-riboflavin group and 442 +/- 80 MUm in the methylcellulose-riboflavin group (p < 0.001). Complete absence of keratocytes in the pre-endothelial stroma was found in none of the corneas treated with dextran-riboflavin and in 42% of the corneas treated with methylcellulose-riboflavin. Visibility of the OCT demarcation line was significantly lower in the methylcellulose-riboflavin group. Kmax and corrected distance visual acuity were improved in the methylcellulose-riboflavin group and stable in the dextran-riboflavin group after 2 years. Endothelial cell density (ECD) was stable in both groups. CONCLUSION: We found deeper structural changes in the methylcellulose-riboflavin group than in the dextran-riboflavin group. This may be explained by different riboflavin solution properties and raises safety concerns. The study also indicates improved effect using methylcellulose riboflavin than dextran-riboflavin, possibly explained by deeper stromal CXL effect. PMID- 30284384 TI - Creation and Location-Specific Revision of a Core Nursing Outcomes Evaluation System Based on Nursing Outcomes Classification for Stroke Inpatients in China. AB - PURPOSE: To screen and create a core nursing outcomes evaluation index system based on NOC for stroke inpatients in China. METHODS: This study adopted the method of Delphi expert consultation, with the degree of consent >4.0 points and the coefficient of variation <0.25 as the standard for inclusion of indexes. RESULTS: The evaluation index system established in this study includes five first-grade indexes, 15 second-grade indexes, and 58 third-grade indexes. CONCLUSION: The evaluation index system of core nursing outcomes for stroke inpatients in China has good specificity and reliability. PRACTICE IMPLICATIONS: The evaluation index system of core nursing outcomes provides a standardized location-specific tool for clinical nurses to evaluate the nursing quality and intervention effect for stroke inpatients in China. PMID- 30284385 TI - Topical cyclosporine-A versus prednisolone for herpetic stromal keratitis: a randomized controlled trial. AB - PURPOSE: To compare topical cyclosporine-A 2% eye drop (Cs-A) with prednisolone acetate 1% eye drop for treatment of herpetic stromal keratitis (HSK). METHODS: In this randomized clinical trial, 38 eyes of 33 patients with HSK were randomly assigned to receive either 2% Cs-A or 1% prednisolone acetate eye drops. All subjects received oral acyclovir 400 mg twice a day. Slit-lamp examination, Scheimpflug tomography corneal optical densitometry (Pentacam(r), Oculus Inc., Wetzlar, Germany), best-corrected visual acuity (BCVA), and intra-ocular pressure (IOP) were evaluated at the first visit, and 14 and 30 days after the treatment. RESULTS: Within-group analysis revealed significant improvement of total cornea optical density after 30 days of treatment in both groups (30.3 +/- 10.5 to 28.3 +/- 9.8, p < 0.001 for prednisolone group, and 30.5 +/- 8.8 to 28.8 +/- 8.3 p < 0.001 for Cs-A group, mean +/- SD). We were not able to disclose any significant difference between the two groups regarding the improvement of cornea optical density (p = 0.66). Best-corrected visual acuity (BCVA) logMAR significantly improved in both groups after 30 days of treatment (0.20 +/- 0.52, p = 0.002 in prednisolone group, and 0.24 +/- 0.31, p < 0.001 in Cs-A group, mean +/- SD). Analysis between groups did not show a significant difference of BCVA improvement (p = 0.45). We did not observe any severe side effect attributable to drugs. CONCLUSIONS: Cs-A 2% and prednisolone acetate 1% topical eye drops are effective for treatment of HSK. PMID- 30284386 TI - Otitis media, antibiotics, and risk of autism spectrum disorder. AB - Otitis media infections and antibiotic treatment have been linked to the risk of developing autism spectrum disorder. Broad-spectrum antibiotics may alter the composition of the gut flora microbiota, which is hypothesized to be involved in the regulation of the immune system. This study examines the interplay among otitis media, antibiotics, and the subsequent risk of developing autism. Based on the entire Danish population, 780,547 children were followed from birth (January 1, 1997 to December 31, 2008) until December 31, 2012. We calculated adjusted hazard ratios and absolute risks of autism with 95% confidence intervals (CIs) related to previous otitis media diagnoses and antibiotic prescriptions redeemed at Danish pharmacies. The absolute risk of autism before age 10 was increased among children with otitis media (1.2% for females and 3.3% for males) and in children who had redeemed an antibiotic prescription (0.6% and 2.7% for females and males) compared to children without a history of otitis media and antibiotics usage (0.4% for females and 1.9% for males). Similarly, we found an increased hazard ratio of autism associated with otitis media (1.83 95% CI 1.71-1.95) and antibiotics usage (1.29 95% CI 1.17-1.43). A history of both otitis media and antibiotic treatment did not further increase the risk of autism. Although the risk of autism was associated with otitis media and treatment with antibiotics, we found little evidence of a synergistic effect between otitis media infections and treatment with antibiotics. Autism Res 2018, 11: 1432-1440. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We investigated whether otitis media ear infections and antibiotic treatment were associated with autism spectrum disorder. Autism was more common in children who had had an otitis media infection or who had been treated with antibiotics. Given the observational nature of our data, our study cannot be used to conclude that otitis media or use of antibiotics cause autism, as our findings may be subject to unobserved confounding. PMID- 30284387 TI - Mutations in the NOD2 gene are associated with a specific phenotype and lower anti-tumor necrosis factor trough levels in Crohn's disease. AB - OBJECTIVE: Nucleotide-binding oligomerization domain-containing protein 2 (NOD2) gene mutations are known to be an important risk factor in the pathogenesis of Crohn's disease (CD). Specific disease phenotypes are associated with the presence of NOD2 gene mutation. One treatment option is to use an anti-tumor necrosis factor (TNF)-alpha agent. Therapeutic drug monitoring (TDM) is usually performed in cases of a loss of response. Our aim was to explore whether NOD2 gene mutations have an effect on the disease phenotype, vitamin D levels, and on TDM in CD patients. METHODS: This was a retrospective genotype-phenotype association study on NOD2 gene mutations in 161 patients with CD. RESULTS: Altogether 55 (34.2%) patients carried at least one mutant allele of NOD2. NOD2 gene mutations were associated with ileocecal disease, ileocecal resection, stricturing and perianal disease, and patients with NOD2 gene mutation had significantly less frequent colonic disease and received an ostomy less frequently. TDM in patients with NOD2 gene mutation showed more frequent anti-TNF trough levels in the subtherapeutic range and lower anti-TNF trough levels than in NOD2 wild-type (WT) patients. CONCLUSIONS: CD patients with NOD2 gene mutation have a specific clinical phenotype and they may require higher doses of anti-TNF agents to achieve sufficient anti-TNF trough levels. They may therefore benefit from a proactive TDM than a reactive approach. This could be another step in the direction of personalized medicine. PMID- 30284388 TI - Vitrectomy with silicone oil tamponade for retinal detachment associated with giant retinal tears: Favourable outcomes without adjuvant scleral buckling. AB - PURPOSE: To evaluate the outcomes of pars plana vitrectomy with silicone oil tamponade in the management of retinal detachment associated with giant retinal tears. METHODS: We reviewed 45 eyes of 42 patients with primary retinal detachment associated with giant retinal tears over 10 years at a tertiary referral centre. Patients underwent 23-gauge vitrectomy without adjuvant scleral buckling by a single surgeon and had follow-up at least 6 months after silicone oil removal. RESULTS: Mean follow-up was 37 +/- 35 months. Seven eyes (16%) had grade C proliferative vitreoretinopathy, and 16 (36%) had a giant retinal tear >=180 degrees at baseline. The primary reattachment rate was 84%, and the overall final anatomical success rate was 98%. The mean Snellen visual acuity equivalent at the final visit was 20/58. Final visual acuity >=20/40 was achieved in 64%. The mean duration of silicone oil tamponade was 10.5 +/- 4 weeks. By the final visit, silicone oil had been removed from 44 eyes (98%). CONCLUSION: The high rates of anatomical and functional success support management of giant retinal tears-associated retinal detachment with vitrectomy without adjuvant scleral buckling. Removal of silicone oil at the earliest possible time helps to avoid complications such as keratopathy, glaucoma and visual loss without apparent reason. PMID- 30284389 TI - Adenoid cystic carcinoma: A study of 19 cases of salivary and extra-salivary tumours diagnosed by fine needle aspiration cytology. AB - BACKGROUND: Adenoid cystic carcinoma (ACC) arises at sites where seromucinous or sweat gland epithelium is present and commonly affects the salivary glands. Rarely it can occur at extra-salivary locations. METHODS: A retrospective analysis of 19 cases of ACC diagnosed on fine needle aspiration cytology (FNAC) over a period of 15 y (2002-2016) was made. RESULTS: Of 19 total cases, there were 10 salivary and 9 extra-salivary ACCs. Extra-salivary tumours were seen in 2 cases each in trachea, tongue and in one case each in bronchus, lung, subcutaneous tissue, maxillary antrum, and external auditory canal. The age ranged from 14-80 y (mean: 49.5 y), 10 patients were male and 9 were female. The smears were highly cellular in 11 cases, moderately cellular in 5 cases while 3 cases were paucicellular. Multilayered dense clusters, tissue fragments, dispersed cells and cup-shaped fragments were seen. Relatively uniform cells with high nuclear: cytoplasmic ratio, hyperchromatic nuclei, irregular margins, and nuclear moulding were observed. Variable sized hyaline globules, finger-like hyaline material, hyaline cylinders, and hyaline cords were noted. The cytologic diagnosis of ACC was rendered in 13 cases while in 6 cases it was one of the differential diagnosis including monomorphic adenoma, membranous variant of basal cell adenoma, adnexal tumour, polymorphous adenocarcinoma, and pleomorphic adenoma (PA). CONCLUSIONS: Cytologists must be aware of varied locations where ACC can occur. A diagnosis of ACC must not rely exclusively on the occurrence of hyaline globules but necessitates a close scrutiny of cellular and nuclear features to avoid diagnostic pitfalls. PMID- 30284391 TI - Fine needle aspiration biopsy cytology of phyllodes tumour and fibroadenoma: A cytomorphological study of 104 cases. AB - BACKGROUND: The cytomorphological features in the distinction between phyllodes tumour (PT) and fibroadenoma (FA) on fine needle aspiration biopsy (FNAB) remains challenging because of the biphasic nature of these lesions and the rarity of PT. METHODS: FNAB smears of histologically confirmed PT (N = 26) and FA (N = 78) cases were retrieved from a retrospective database interrogation from the Department of Cytology/Tissue Pathology, ICPMR Pathology West (Cerner Millennium) in Westmead Hospital. For each case, two smears were selected, de-identified and independently reviewed by four observers comprising two cytologists and two cytopathologists. Cytological parameters examined included detailed evaluation of smear cellularity, epithelial and stromal components as well as the smear background. RESULTS: The cytological features of moderate to marked stromal cellularity and stromal nuclear atypia were more evident in PT than in FA, identified by three out of four observers. The epithelial characteristics, presence of macrophages, multinucleated giant cells and blood vessels showed no statistically significant differences in the distinction between the two lesions. CONCLUSION: The results of this study indicate that in all of the cytological features assessed for PT and FA, no single cytological feature was found to be statistically significant in identifying PT across all observers. This reflects the overlap of cytological features seen in these lesions. FNAB cytology cannot reliably distinguish FA and PT.

AB - Noninvasive imaging of the murine pulmonary vasculature is challenging due to the small size of the animal, limits of resolution of the imaging technology, terminal nature of the procedure, or the need for intravenous contrast. We report the application of laboratory-based high-speed, high-resolution x-ray imaging, and image analysis to detect quantitative changes in the pulmonary vascular tree over time in the same animal without the need for intravenous contrast. Using this approach, we detected an increased number of vessels in the pulmonary vascular tree of animals after 30 min of recovery from a brief exposure to inspired gas with 10% oxygen plus 5% carbon dioxide (mean +/- standard deviation: 2193 +/- 382 at baseline vs. 6177 +/- 1171 at 30 min of recovery; P < 0.0001). In a separate set of animals, we showed that the total pulmonary blood volume increased (P = 0.0412) while median vascular diameter decreased from 0.20 mm (IQR: 0.15-0.28 mm) to 0.18 mm (IQR: 0.14-0.26 mm; P = 0.0436) over the respiratory cycle from end-expiration to end-inspiration. These findings suggest that the noninvasive, nonintravenous contrast imaging approach reported here can detect dynamic responses of the murine pulmonary vasculature and may be a useful tool in studying these responses in models of disease. PMID- 30284392 TI - High-throughput doping control analysis of 28 amphetamine-type stimulants in equine plasma using hydrophilic interaction liquid chromatography-tandem mass spectrometry. AB - A hydrophilic interaction liquid chromatography-tandem mass spectrometry method (HILIC-MS/MS) was developed for the simultaneous determination of 28 amphetamine type stimulants (ATSs) in equine plasma for doping control analysis. In this method, stimulants were recovered from equine plasma by liquid-liquid extraction (LLE) at pH 9.5 using methyl tert-butyl ether and detected on a Thermo Finnigan triple quadrupole mass spectrometer operating in positive-ion mode electrospray ionization. All stimulants were eluted within 7 minutes and baseline separation was achieved for isomeric and isobaric compounds using HILIC chromatography. Extraction efficiency was greater than 80% and matrix effect was acceptable for most stimulants. The limit of detection (LOD) was in the range of 10-50 pg/mL and the lower limit of quantification (LLOQ) was in the range of 50-100 pg/mL. Quadratic regression was employed for quantification and the dynamic range of quantification was 50-10000 pg/mL. Confirmatory analysis criteria were established using product ion ratios and retention time. The limit of confirmation (LOC) was in the range of 20-100 pg/mL. Stability study results indicated that some stimulants were unstable in equine plasma at room temperature and 4 degrees C. However, all the stimulants studied were stable at -20 degrees C and - 80 degrees C for the 6 month study period. PMID- 30284395 TI - High rate of failed visual-acuity measurements with the Amsterdam Picture Chart in screening at the age of 36 months. AB - PURPOSE: In the Netherlands, youth health care physicians and nurses screen all children for general health disorders at Child Health Care Centers. As part of this, the eyes are screened seven times, with the first visual acuity (VA) measurement at 36 months with the Amsterdam Picture Chart (APK). The suitability of the APK has been questioned. METHODS: Children born between July 2011 and June 2012 born in the provinces Drenthe, Gelderland and Flevoland and invited for screening at 36 months were eligible. Parents were sent the APK picture optotypes to practise with their children in advance. Data were collected from electronic screening records. The Dutch vision screening guideline prescribes that children with VA <5/6, or one line interocular difference (not logMAR, however) should be retested or referred. RESULTS: Of 10 809 eligible children, 1546 did not attend and 602 attended but had no VA measurement at age 36 months, 247 of these were under orthoptic treatment. Of the 8448 children examined, VA was sufficient in 5663 (67.0%) and insufficient in 1312 (15.5%). In 1400 (16.6%), the measurement of VA itself failed. In 73 (0.9%), data were missing. Of the 216 children with 2 failed VA measurements, 150 (69%) were not referred, and measurement of VA was deferred to the next general screening examination at 45 months. CONCLUSION: Although most parents had practised the APK picture optotypes at home with their children, the rate of failed APK measurements plus the measurements with insufficient VA was 32.1% at 36 months. Similar rates have previously been reported for Lea Symbols and HOTV, permitting the conclusion that measurement of VA at the age of 36 months cannot be recommended as a screening test in the general population. PMID- 30284393 TI - Postoperative management in cataract surgery: nepafenac and preservative-free diclofenac compared. AB - PURPOSE: Current cataract surgery guidelines recommend routine use of topical nonsteroidal anti-inflammatory drugs (NSAIDs) in preventing pseudophakic cystoid macular oedema (PCME). Here, we compare the clinical efficacy and tolerability of two potent NSAIDs, nepafenac and preservative-free diclofenac following cataract surgery. METHODS: Randomized, double-blind, prospective single-centre study. Ninety-six eyes of 95 patients undergoing routine cataract surgery were randomized 1:1 either to nepafenac (Nevanac, 1 mg/ml) or diclofenac (Dicloabak, 1 mg/ml) for 3 weeks. Seventy-three patients accounting for 73 eyes completed the entire follow-up. Aqueous flare and central retinal thickness (CRT) analysis were conducted preoperatively and at control visits 28 days and 3 months after surgery. A structured home questionnaire and interview were used to record any adverse effects of the topical medications, subjective visual recovery and the dispenser's ease of use. RESULTS: No differences were observed between the groups for aqueous flare, CRT, speed of recovery or visual acuity gain. Seven patients (16%) on nepafenac and 20 patients (48%) on preservative-free diclofenac reported symptoms related to topical use of NSAID medications (p = 0.001). CONCLUSION: No differences in clinical efficacy were found between potent NSAIDs, while tolerability might be an issue. PMID- 30284394 TI - Association between schizophrenia and autism spectrum disorder: A systematic review and meta-analysis. AB - Schizophrenia and autism spectrum disorder (ASD) are significant public health problems. Scientists have recently explored the association between schizophrenia and ASD, but the findings are inconsistent. Thus, we conducted a systematic review and meta-analysis of epidemiological studies to examine the association between schizophrenia and ASD. PubMed, Embase, and the Cochrane Library were used for literature searches to identify eligible studies published in English before October 2, 2017. Relevant studies estimating the association between schizophrenia and ASD were included. The meta-analysis of the prevalence of schizophrenia in individuals with ASD encompassed 1,950,113 participants and 14,945 individuals with ASD. A random-effects model was chosen to synthesize the effect sizes of individual studies. The prevalence of schizophrenia was significantly higher in individuals with ASD than in controls (odds ratio = 3.55, 95% confidence interval: 2.08-6.05, P < .001). Both sensitivity analysis and publication bias testing revealed that the findings were robust. The systematic review of the prevalence of ASD in individuals with schizophrenia encompassed 930 participants. The prevalence of ASD in individuals with schizophrenia ranged from 3.4 to 52%. The systematic review and meta-analysis showed a significant association between schizophrenia and ASD. Autism Research 2018, 11: 1110-1119. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This systematic review and meta-analysis explored the association between schizophrenia and ASD. We found that the prevalence of schizophrenia was significantly higher in individuals with ASD than in controls and the prevalence of ASD in individuals with schizophrenia ranged from 3.4 to 52%. A comprehensive estimation of schizophrenia and ASD has important implications for the diagnosis, treatment, prognosis, and development of a fundamental understanding of these disorders.

PMID- 30284398 TI - Controlled Formation of a Main Chain Supramolecular Polymer Based on Metal-Ligand Interactions and a Thiol-Ene Click Reaction. AB - Supramolecular polymers with multiple functionalities and hierarchical structures have received considerable attention and become a hot research topic over the past years. Herein, a main-chain supramolecular polymer has been successfully fabricated by using metal-ligand interactions and a thiol-ene click reaction. 1 H NMR, UV/Vis, DOSY, and viscosity measurements were carried out to investigate the molecular recognition and the process of supramolecular polymerization. From the study, the orthogonality between thiol-ene click reactions and the terpyridine metal ions complexation behavior was testified, and supramolecular polymeric assemblies could be constructed by a one pot method. In the meantime, due to the incorporation of metal-ligand interactions, the supramolecular polymer shows stimuli-responsive properties toward chemical stimuli. Hence, this work could provide a methodology for developing supramolecular polymers as smart materials. PMID- 30284397 TI - A1899, PK-THPP, ML365, and Doxapram inhibit endogenous TASK channels and excite calcium signaling in carotid body type-1 cells. AB - Sensing of hypoxia and acidosis in arterial chemoreceptors is thought to be mediated through the inhibition of TASK and possibly other (e.g., BKC a ) potassium channels which leads to membrane depolarization, voltage-gated Ca entry, and neurosecretion. Here, we investigate the effects of pharmacological inhibitors on TASK channel activity and [Ca2+ ]i -signaling in isolated neonatal rat type-1 cells. PK-THPP inhibited TASK channel activity in cell attached patches by up to 90% (at 400 nmol/L). A1899 inhibited TASK channel activity by 35% at 400 nmol/L. PK-THPP, A1899 and Ml 365 all evoked a rapid increase in type 1 cell [Ca2+ ]i . These [Ca2+ ]i responses were abolished in Ca2+ -free solution and greatly attenuated by Ni2+ (2 mM) suggesting that depolarization and voltage gated Ca2+ -entry mediated the rise in [Ca2+ ]i. Doxapram (50 MUmol/L), a respiratory stimulant, also inhibited type-1 cell TASK channel activity and increased [Ca2+ ]i. . We also tested the effects of combined inhibition of BKC a and TASK channels. TEA (5 mmol/L) slightly increased [Ca2+ ]i in the presence of PK-THPP and A1899. Paxilline (300 nM) and iberiotoxin (50 nmol/L) also slightly increased [Ca2+ ]i in the presence of A1899 but not in the presence of PK-THPP. In general [Ca2+ ]i responses to TASK inhibitors, alone or in combination with BKC a inhibitors, were smaller than the [Ca2+ ]i responses evoked by hypoxia. These data confirm that TASK channel inhibition is capable of evoking membrane depolarization and robust voltage-gated Ca2+ -entry but suggest that this, even with concomitant inhibition of BKC a channels, may be insufficient to account fully for the [Ca2+ ]i -response to hypoxia. PMID- 30284399 TI - Effects of using lubricant during the speculum examination for Pap smear collection. AB - OBJECTIVE: To evaluate the effect of using lubricant during speculum examination for Pap smear collection. METHODS: A cross-sectional study was conducted involving 83 patients attending a medical school clinic. Participants were allocated into two groups: Group 1-Lubricant using; Group 2-No lubricant using. All patients were submitted to two successive collections and after were asked about their level of discomfort. Differences between groups regarding quality, artifacts, cytology, and level of discomfort were observed through chi-squared test. Odds ratios and 95% confidence intervals were also estimated. Statistical significance was set at P < .05. RESULTS: No significant differences between groups regarding quality, presence of artifacts, and cytological results were observed. Significant lower discomfort level in Group 1 (lubricant using). CONCLUSION: The use of vaginal lubricant did not affect the results of cytology and could be a useful tool to reduce the discomfort during Pap smear collection.

PMID- 30284401 TI - Detection of aquaporin-4 antibodies for patients with CNS inflammatory demyelinating diseases other than typical MS in Lithuania. AB - OBJECTIVES: Neuromyelitis optica (NMO) is frequently associated with aquaporin-4 autoantibodies (AQP4-Ab); however, studies of NMO in Lithuania are lacking. Therefore, the main objective of our study is to assess positivity for AQP4-Ab in patients presenting with inflammatory demyelinating central nervous system (CNS) diseases other than typical multiple sclerosis (MS) in Lithuania. MATERIALS AND METHODS: Data were collected from the two largest University hospitals in Lithuania. During the study period, there were 121 newly diagnosed typical MS cases, which were included in the MS registry database. After excluding these typical MS cases, we analyzed the remaining 29 cases of other CNS inflammatory demyelinating diseases, including atypical MS (n = 14), acute transverse myelitis, TM (n = 8), acute disseminated encephalomyelitis, ADEM (n = 3), clinically isolated syndrome, CIS (n = 2), atypical optic neuritis, ON (n = 1), and NMO (n = 1). We assessed positivity for AQP4-Ab for the 29 patients and evaluated clinical, laboratory, and instrumental differences between AQP4-Ab seropositive and AQP4-Ab seronegative patient groups. RESULTS: AQP4-Ab test was positive for three (10.3%) patients in our study, with initial diagnoses of atypical MS (n = 2) and ADEM (n = 1). One study patient was AQP4-Ab negative despite being previously clinically diagnosed with NMO. There were no significant clinical, laboratory, or instrumental differences between the groups of AQP4-Ab positive (3 [10.3%]) and negative (26 [89.7%]) patients. CONCLUSIONS: AQP4-Ab test was positive for one-tenth of patients with CNS inflammatory demyelinating diseases other than typical MS in our study. AQP4-Ab testing is highly recommended for patients presenting with not only TM and ON but also an atypical course of MS and ADEM. PMID- 30284400 TI - Effect of a 9-week exercise training regimen on expression of developmental genes related to growth-dependent fat expansion in juvenile rats. AB - This study examined the association between changes in mRNA expression of development-related genes including those of the homeobox (Hox) family and growth dependent increases in inguinal, mesenteric, and epididymal white adipose tissue (WAT) at 4, 6, 10, and 14 weeks of age in rats. We also examined the effects of a 9-week exercise training regimen starting at 5 weeks of age on the mRNA levels of the genes of interest. HoxC8, HoxC9, Gpc4, Bmpr1a, Ppargamma, Pgc1alpha, Adrb3, Hsl, leptin, and adiponectin in each type of WAT - except HoxA5, Gpc4, and Pgc1alpha in epididymal - showed a positive association between WAT weights and WAT mRNA levels; however, the slope of the regression lines exhibited fat depot specific differences. HoxA5 showed no significant association, and Gpc4 and Pgc1alpha showed a negative association in epididymal WAT. After exercise training, the mean HoxA5, HoxC8, HoxC9, HoxC10, Gpc4, Ppargamma, and Pgc1alpha mRNA levels in inguinal WAT were outliers on the regression line between mean mRNA level and WAT weight in control rats - that is, mean HoxA5 and Pgc1alpha mRNA level was higher, whereas HoxC8, HoxC9, HoxC10, Gpc4, and Ppar levels were lower in exercise-trained rats than in same-age controls. Ppargammagamma and adiponectin levels were upregulated in epididymal WAT, while HoxA5 was downregulated, but HoxC9, Gpc4, Ppargamma, and adiponectin levels were upregulated in mesenteric WAT. These results suggest that some of the developmental genes tested may have fat depot-specific roles in the growth dependent expansion of WAT, and that Hox genes that are activated in response to exercise training also vary among different WAT types. PMID- 30284403 TI - Predicting the outcome of laser peripheral iridotomy for primary angle closure suspect eyes using anterior segment optical coherence tomography. AB - PURPOSE: Develop an algorithm to predict the success of laser peripheral iridotomy (LPI) in primary angle closure suspect (PACS), using pretreatment anterior segment optical coherence tomography (ASOCT) scans. METHODS: A total of 69 eyes with PACS underwent LPI and time-domain ASOCT scans (temporal and nasal cuts) were performed before and after LPI. After LPI, success is defined as one or more angles changed from closed to open. All the pretreatment ASOCT scans were analysed using the Anterior Segment Analysis Program to derive anterior chamber angle (ACA) measurements. The measurements for each angle were ordered along with angle-independent measurements totalling to 42 measurements which serve as features for the prediction algorithm. Two masked glaucoma fellowship-trained ophthalmologists graded the pre-LPI ASOCT scans to determine whether LPI was likely to successful. RESULTS: There were 42 (60.9%) eyes that fulfilled the criteria for success after LPI. Iris concavity, angle recess area (750 MUm) and iris concavity ratio showed the highest predictive score and were selected using correlation-based subset selection method. These features were classified into two ('successful' and 'unsuccessful') categories using a Bayes classifier. The algorithm predicted the success of LPI with 79.28% cross validation accuracy, which was superior to the predictive accuracy of the ophthalmologists (kappa 0.497 and 0.636 respectively). CONCLUSION: Using pretreatment ASOCT scans, our algorithm was superior to ophthalmologists in predicting the success of LPI for PACS eyes. This novel algorithm could aid decision making in offering LPI as a prophylaxis for PACS. PMID- 30284404 TI - Synthesis and antifungal activities of novel thiophene-based stilbene derivatives bearing an 1,3,4-oxadiazole unit. AB - BACKGROUND: Natural stilbenes (especially resveratrol and its derivatives) are well-known phytoalexins that are active against many plant diseases. However, oxidative degradation and low bioavailability limit their exogenous application as fungicides on crops. In this study, a new class of resveratrol-inspired thiophene-based stilbene derivatives bearing an 1,3,4-oxadiazole unit was synthesized and the derivatives' antifungal activities against phytopathogenic fungi were investigated. RESULTS: The results revealed that compounds 5h and 5j exhibited improved antifungal activity against Botrytis cinerea with median effective concentrations (EC50 ) of 168.5 and 155.4 ug mL-1 , respectively, which were superior to the EC50 of resveratrol (263.1 ug mL-1 ). Compound 5j was shown to effectively control disease development in B. cinerea-infected tomatoes in vivo. Notably, considerably abnormal mycelial morphology and increased cell membrane conductivity were observed in the presence of compound 5j. CONCLUSION: A new class of thiophene-containing stilbene derivatives was designed and synthesized. Bioassay results showed that compound 5j exhibited promising antifungal activity, suggesting practical potential for fungal disease control. (c) 2018 Society of Chemical Industry. PMID- 30284406 TI - Pancreatic mixed acinar-neuroendocrine carcinoma, a unique diagnostic challenge on FNA cytology: A small series of two cases with literature review. AB - Mixed acinar-neuroendocrine carcinoma (MANEC) of the pancreas is a rare tumor. We present two cases of MANEC diagnosed on endoscopic ultrasound (EUS) guided fine needle aspiration (FNA). The first patient is a 33-year-old male who had a 3.6 cm mass in the uncinate process and liver metastasis. The second patient is a 66 year-old male with a 10 cm mass in the pancreatic tail. The FNA smears from both cases were hypercellular with neoplastic cells in loosely cohesive clusters and many naked nuclei. In both cases, the tumor cells were positive for CKAE1/3, synaptophysin, chromogranin, and trypsin by immunohistochemistry. Final diagnoses of MANEC were rendered based on cytological features and immunohistochemical profiles. To date, 44 cases of MANEC have been reported in the English literature, only three of which were diagnosed on cytopathology specimens before surgical resection. Our report adds two more cases diagnosed on cytopathology alone. Herein, we discuss the various cytomorphologic and clinical features of MANEC and present a brief review of the literature. Diagn.

AB - BACKGROUND: The aim of this study was to evaluate the clinical performance of the Cobas 4800 HPV test and the Aptima HPV assay for the detection of CIN2+ disease in women referred to colposcopy with minor cytological abnormalities. METHODS: ThinPrep liquid-based cytology samples were collected from 562 women referred to colposcopy with minor cytological abnormalities. HPV testing by both assays was performed on these samples. Clinical performances for detection of histologically diagnosed CIN2+ and CIN3+ were calculated. RESULTS: HPV prevalence by the Cobas 4800 HPV test was 58.2% and 53.0% women tested positive with the Aptima HPV assay in the entire study population. The Aptima HPV assay and the Cobas 4800 HPV test displayed equivalent sensitivity of 90.2% (95%CI, 83.4-94.9) for the detection of CIN2+ disease. However, the Aptima HPV assay displayed greater specificity of 61.0% (95% CI, 54.0-68.0) when compared to the Cobas 4800 HPV test 53.0% (95% CI, 46.0-60.0), and this was significantly higher (P = .0004). The Aptima HPV assay also displayed higher specificity 76.5% (95% CI, 66.0-85.0) in the ASCUS category in comparison to the Cobas 4800 HPV test 65.0% (95% 54.0-75.0) which was statistically significant (P = .004). CONCLUSIONS: Both the tests displayed similar sensitivity. However, the Aptima HPV assay was significantly more specific in the identification of women with CIN2+ disease in a colposcopy referral population. PMID- 30284408 TI - Disc haemorrhages in Polish Caucasian patients with normal tension glaucoma. AB - AIM: The aim of this observational study was to evaluate the epidemiology of disc haemorrhages (DH) in Polish patients with normal tension glaucoma (NTG) and their association with some risk factors. MATERIAL AND METHODS: The group studied consisted of 274 Caucasian patients with NTG (410 eyes) divided into those with disk haemorrhages (DH+, = 94 eyes in 81 patients) and those without disc haemorrhages (DH-, = 316 eyes in 193 patients). Ophthalmic examinations with visual field (VF) testing were carried out in these patients every 3 months for at least 18 months. The medical history was recorded taking glaucoma, other ophthalmic diseases, chronic general disorders and vascular risk factors into account. RESULTS: Unilateral and bilateral DH were observed more frequently in women (p = 0.0010). Maximum IOP was significantly higher in the DH+ group (p = 0.000026). Notches and peripapillary atrophy were found with similar frequency in DH+ and DH- patients (p = 0.4631). The mean defect (MD) in the VF at the time of diagnosis was lower in the DH+ group (-6.27 dB) than in the DH group (-10.14 dB), (p = 0.000055). The initial MD in the DH+ group had a positive correlation with maximum initial IOP. A progressive loss of VF was observed in 206 eyes with NTG (50.2%), with a mean of 0.72 dB/year. The progression was more frequent in DH+ patients (78.4% versus 41.1%), but there were no statistically significant differences in the rate of progression between DH+ and DH- patients (p = 0.46). The morphology of early scotoma depended on the presence of DH (p < 0.00001), and early scotoma in the DH+ group was more frequently localized paracentrally. There was a significant difference in a number of antiglaucoma drops between DH+ and DH patients (p < 0.00001). There were no differences in the frequency of migraines between both groups (p = 0.31). General hypotension was observed with similar frequency in the DH+ DH- groups (p = 0.3). General hypertension was less frequent in DH+ patients (p = 0.041), especially in women (p = 0.000027). Diabetes mellitus (DM) was significantly less frequent (21.3%) in patients with DH+ (3.7%) than in the DH- group (p = 0.000852), especially among the women (p = 0.000216). CONCLUSION: In our study, DH were more frequent both unilaterally and bilaterally in women. Initial intraocular pressure (IOP) was higher in NTG patients with DH, and early scotoma was localized in the paracentral area of the VF. Disc haemorrhages (DH) were less frequent in women with general hypertension and with diabetes mellitus. PMID- 30284409 TI - Supercritical Fluid-Assisted Porous Microspheres for Efficient Delivery of Insulin and Inhalation Therapy of Diabetes. AB - Pulmonary delivery of drugs has attracted increasing attention in healthcare, as the lungs are an easily accessible site for noninvasive systemic delivery of drugs. Although pulmonary inhalation of porous microparticles has been shown to sustain drug delivery, there are limited reports on efficient delivery of insulin and inhalation therapy of diabetes based on supercritical carbon dioxide (SC-CO2 ) technology. Herein, this study reports the fabrication of insulin-loaded poly-l lactide porous microspheres (INS-PLLA PMs) by using the SC-CO2 technology, and their use as an inhalation delivery system potentially for diabetes therapy. Biocompatibility and delivery efficiency of the PLLA PMs in the lungs are investigated. The PLLA PMs show negligible toxicity to lung-derived cells, resulting in no significant reduction in cell viability, as well as levels of various inflammatory mediators such as interleukin (IL)-6, IL-8, and tumor necrosis factor-alpha, compared with the negative control group. INS-PLLA PMs are further efficiently deposited in the trachea and the bronchi of superior lobes of the lungs, which exhibit pronounced hypoglycemic activity in induced diabetic rats. Together, the results demonstrate that the INS-PLLA PMs have a strong potential as an effective strategy for inhalation treatment of diabetes. PMID- 30284410 TI - Immunohistochemical analysis of OTP and NKX6.1 in neuroendocrine tumors of the lung and pancreas. AB - BACKGROUND: Homeobox transcription factors have demonstrated utility in diagnosing neuroendocrine tumors. Orthopedia homeobox protein (OTP) has a well defined role in embryonic neurodevelopment and has also been described as a prognostic marker in lung neuroendocrine tumors (NET). Additionally, NK6 homeobox 1 (NKX6.1) has been described to be necessary for the development of neuroendocrine cells in the pancreas. We evaluated immunohistochemical (IHC) expression of OTP and NKX6.1 to determine their utility in the diagnosis of NETs from lung and pancreas fine-needle aspirations (FNA). METHODS: Our study examined 50 FNA specimens, including 30 primary pulmonary NETs (8 carcinoid tumors (CT), 6 atypical carcinoids (AC), 11 small-cell neuroendocrine carcinomas (SCNEC), 5 large-cell neuroendocrine carcinomas (LCNEC)) and 20 primary pancreatic NETs (17 well-differentiated pancreatic neuroendocrine tumors (PanNET) and 3 poorly differentiated pancreatic neuroendocrine carcinomas (PanNEC)). IHC expression of OTP, NKX6.1, and Ki-67 was evaluated on FNA cell blocks. RESULTS: Half of the pulmonary TC tumors expressed OTP, while only 17% of AC and 20% of LCNEC expressed OTP. Neither SCNECs nor any pancreatic NET expressed OTP. In contrast, intermediate and high-grade tumors expressed NKX6.1 (LCNEC-80%, SCNEC-82%, and AC 83%) more often than low-grade tumors (TC-63%, PanNET-71%). All three PanNECs expressed NKX6.1. CONCLUSIONS: OTP may be useful in diagnosing well differentiated NETs of pulmonary origin. NKX6.1 may have utility in segregating high from low-grade NETs of both pulmonary and pancreatic origin, although other methods will be required to determine site of origin.

AB - PURPOSE: To examine the outcome of the use of donor sclera as spacer material in complicated cases of strabismus surgery. METHODS: A retrospective cohort study on patients with complicated thyroid-associated ophthalmopathy (TAO) (n = 42) or congenital strabismus (n = 75). Patients underwent strabismus surgery during 1994 2014. The surgical results were evaluated in terms of the reduction in the angle of deviation, the need for re-operation, complications and patient satisfaction. RESULTS: The majority of the TAO patients underwent surgery for vertical strabismus (n = 25). The vertical angle of deviation in the primary position was significantly reduced from a median of 23 prism dioptres (PD) to 2 PD (n = 35, p < 0.001). The horizontal angle of deviation in primary position for TAO patients with esotropia was significantly reduced, from a median of 35 PD to 2 PD (n = 17, p < 0.001). The majority of the congenital cases had horizontal strabismus (esotropia = 29, exotropia = 27). The angle of deviation in esotropia was reduced from a median of 29 PD to 8 PD (n = 36, p < 0.001) and in exotropia from 30 PD to 10 PD (n = 34, p < 0.001). Most of the patients were satisfied with the outcome of surgery, and only 12% required re-operation within 2 years. CONCLUSION: This is the first clinical study on the use of donor sclera as spacer material in complicated cases of strabismus surgery. The surgical results were good in terms of the reduction in the angle of deviation, the need for re-operation, complications and patient satisfaction, supporting the use of donor sclera for strabismus surgery.

AB - PURPOSE: To describe the change in the retinal morphology after full macular translocation (FMT) for exudative age-related macular degeneration (AMD) and identify predictive factors for the visual outcome. METHODS: All patients who underwent FMT from December 2008 through July 2013 were selected. Exclusion criteria were FMT for other disease than AMD, age <60 years, <12 months of follow up or no available images. Spectral domain optical coherence tomography, fundus autofluorescence, fluorangiography and indocyanine green angiography were evaluated. RESULTS: In total, 51 patients were included with a mean follow-up of 30 months. The presence of the external limiting membrane (ELM) was a significant predictor for a favourable visual outcome 1 year after FMT (OR = -0.30). Other significant predictive factors were the absence of intraretinal fluid (OR = 0.28) and the mixed choroidal neovascularization type (OR = -0.47), whereas nonresponders (OR = 0.41) and fibrotic lesions (OR = 0.35) were less likely to have a good visual function after surgery. CONCLUSION: Full macular translocation (FMT), that permits to relocate the diseased macula onto an area of unaffected retinal pigment epithelial and choroid, can restore the anatomy and visual function in some patients with AMD when the outer retina layers are not irreversibly damaged. The presence of the ELM seems to be the most reliable factor in predicting the functional outcome. PMID- 30284415 TI - [HEPATOCELLULAR CARCINOMA. GENDER ASPECTS OF CARCINOGENESIS].

PMID- 30284416 TI - MELD SCORE CORRELATION WITH LABORATORY FINDINGS AND COMPLICATIONS OF HEPATITIS C CAUSED LIVER CIRRHOSIS. AB - Introduction: Model for End-Stage Liver Disease (MELD) is a scoring system used to estimate the severity of chronic liver disease. Score is based on objective variables and predicts survival among different populations of patients. Study Aim. The aim of the study was to retrospectively analyze potential connection between MELD score and laboratory findings and complications of hepatitis C caused liver cirrhosis. Materials and Methods: A retrospective cross-sectional study based on data from Riga East Clinical University Hospital from the time period of 2010 to 2014 was performed. Original protocol and database were developed with consequential data statistical analysis using IBM SPSS Statistics ver.20.0. Results: In total 221 cirrhosis cases were enrolled in the study. 128 (58%) cases were male and 93 (42%) female. Mean age was 52.7 +/- 13.4 years. Statistically significant correlation was found between leukocytes (r = 0.4, p < 0.001), blood urea (r = 0.4, p < 0.001), serum albumin (r = -0.4, p < 0.001), C reactive protein (r = 0.4, p < 0.001) and MELD score. Higher leukocytes, higher urea, C-reactive protein and lower serum albumin rates give higher MELD score. At the time of hospitalization 208 (94%) of the patients had different complications of liver cirrhosis. Correlation between MELD score varied significantly with esophageal varices (r = 0.2, p < 0.05) and esophageal vein bleeding (r = 0.2, p < 0.05). Results show, if patient is present with esophageal varices and esophageal vein bleeding, MELD score is higher. Conclusion: Patients with higher leukocytes, blood urea nitrogen and lower serum albumin level are presenting higher MELD score. In patients who presented with esophageal varices and esophageal vein bleeding, higher MELD score was observed.

AB - Objective: To compare the clinical, endoscopic picture and morphological changes of the intestinal mucosa in patients with primary sclerosing cholangitis (PSC). Materials and methods: 31 patients with PSC (women - 15 men - 16) were included in study group. The diagnosis of ulcerative colitis (UC) was established in 8 patients, Crohn's disease (CD) - in 5, unclassified colitis (UCC) - in 7, and 11 patients had no clinical and endoscopic signs of IBD. The control group consisted of 30 patients with IBD: UC - 20 patients, CD - 10 persons. All the patients performed ileocolonoscopy (ICS) with multiple biopsy and histological examination of material. Results: The prevalence of IBD in patients with PSC was 64.5%. IBD with PSC was characterized by extensive colitis with mild clinical activity. Morphological activity of IBD associated with PSC was usually moderate and severe. Morphological activity of disease in IBD/PSC group was lower than in UC alone (p < 0.05). IBD onset came before PSC symptoms (p < 0.05). Distal gradient of inflammation in colon predominated in IBD/PSC group when disease starts with IBD symptoms, in case of PSC symptoms - proximal gradient was more frequent. In IBD/PSC group affected ileum were detected in a third of cases, including CD ileitis - 60%, backwash ileitis in UC (NCC) in 26.7%, that was significantly frequently than in UC alone (p = 0.02). Within the IBD/PSC group 30% of patients with colitis were without damaging of rectum. In all the patients with PSC without clinical, endoscopic signs of colitis polymorphocellular infiltration of mucosa were founded. Eosinophilic infiltration of mucosa in group of PSC met significantly more frequently than in other study groups. Fibrosis of intestinal mucosa was founded significantly more frequently in group of PSC without IBD compared with UC/PSC and UC patients, but not with CD group. Conclusions: For IBD in PSC extensive colitis without lesions of the rectum, backwash ileitis are common. There are some morphological differences in the intestinal lesions within the IBD/PSC patients depending on the type of disease onset. There is a dissociation between low clinical activity and intensive morphological inflammation. When PSC had no clinical features of IBD, a microscopic ileocolitis (characterized by eosinophilic infiltration and fibrosis of the intestinal mucosa) without nosological classification was founded in all patients.

AB - Objective: To evaluate the diagnostic value of MMP-9, TIMP-1 and 2 as non invasive markers of liver fibrosis in the NAFLD to improve the management of patients with this pathology. Materials and methods: We examined 99 patients with NAFLD and different stages of fibrosis, 83 men, 16 women, median age 45 (range 40 55) years. We assessed of risk factors for liver fibrosis in the NAFLD, anthropometric indicators, biochemical analysis of blood, abdominal ultrasonic studies, the levels of MMP-9, TIMP-1 and 2. Depending on the stage of fibrosis (0 4), established as a result of liver elastometry (Fibroscan), patients were divided into 5 groups: n = 27, n = 22, n = 23, n = 14, n = 13, respectively. Results: Between the groups in medical history, physical examination, calculation of BMI and the ratio of waist to hip volume (W/H) no significant differences were found. 64,6% of patients had abdominal obesity (BMI - 31,5 (29,1-33,9), W/H - 1,02 (1,01-1,05). Obesity and abdominal obesity (BMI, W/H) had a significant positive relationship of moderate streight (rs = (0,257), p < 0,04, rs = (0,301), p < 0,02, respectively), with the stage of liver fibrosis. The groups were significant differences in the level of glucose, total bilirubin (p < 0,04, p < 0,03, respectively). At the time of the examination, 57,5% of patients had steatosis, other patients had steatohepatitis. No significant differences in the level of liver function tests (ALT, AST) in the study groups were found. Significant differences were found in level of TIMP-2 (p < 0,04). TIMP-2 had a significant positive correlation with the severity of fibrosis in the hepatic tissue (rs = (0,349), p < 0,004). Conclusion: TIMP-2 may be considered as a potential non-invasive marker for the diagnosis of liver fibrosis in patients with NAFLD.

AB - Chronic obstructive pulmonary disease is a set of clinical processes that have in common a chronic and progressive obstruction to airflow, with episodes of exacerbation. These exacerbations are more frequent and severe over time, deteriorating the lung function. The main cause of exacerbations is bacterial infection. There are multiple guidelines and documents that statement the management of this pathology. However, they focus primarily on the treatment during the stable phase. This document addresses the problem of acute exacerbation due to an infection from a multidisciplinary perspective, focusing on the integral approach to the process, and including etiology, microbiological studies, resistance to antimicrobials, risk stratification and initial empirical therapeutic management (antibiotic and concomitant). In addition, it includes an approach to more complex aspects such as the management of special populations (elderly and immunosuppressed) or therapeutic failure. Finally, more controversial topics such as prophylaxis of infection or palliative treatment are specifically discussed.

AB - Aim of the research: To study the dynamics of endothelial dysfunction (ED) laboratory markers depending on the functional state of the liver in patients with severe forms of liver cirrhosis (LC). Materials and methods: 387 patients with LC were examined. In order to study the laboratory indexes of ED, levels of antitrombin (AT) III, D-dimer, von Willebrand Factor (wWF), endothelin-1 (Et-1) were determined. The extent of liver damage was determined using C13-methacetin breath test (C13-MBT) and taking into account the results of specially designed tests (Forns, FibroIndex, FIB-4, APRI, HALT-C, MDA, GUCI, FPI). Results: Our investigations confirm the presence of ED in patients with LC. The analysis of the results shows a dependincy between the severity of ED laboratory indexes and the level of LC severity: a progressive aggravation of ED indexes in proportion to liver damage severity growth. Conclusions: 1. Vessel ED is observed in patients with LC, which is manifested in the derangement of its biological markers concentration, namely Et-1, vWF, AT III and D-dimer. 2. In patients with LC a dependincy between the ED indexes and level of liver damage severity according to Child-Pugh was determined, namely the progression of biochemical ED markers of blood serum depending on the severity of liver damage according to C13 MBT results combined with the results of specialy designed tests (Forns, FibroIndex, Fib-4, APRI, HALT-C, MDA, GUCI, FPI).

AB - Purpose: The purpose of this study was to investigate the annual dynamics of the functional state of the liver of rats with experimental hepatitis on early period of intoxication. Materials and methods: This research was conducted for three years on 172 adult male rats Wistar. The toxic hepatitis was caused by subcutaneous injection three times a 50% oil solution of carbon tetrachloride. The studies were conducted in the winter (January), summer (June-July), spring (April) and autumn (October) on the 4th day after the last administration of the toxin. Activity of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), the level of total lipids (TL), total bilirubin (TB), malondialdehyde (MDA) and thymol (T) using standard sets of Biotest "Lachema" were determined in the blood serum. Statistic processing of primary chronograms of investigated parameters was performed with the program "sosinor analysis." Results: It was found that in the control animals was dominated by annual and circannual rhythms of the liver functions and in the spectra of the studied parameters were observed several subdominant harmonic. The maxima of liver function detected to the different time intervals on an annual scale, that is, they were not coordinated with each other. On day 4 experimental hepatitis was increased the average annual of study functions (with the exception of TL) and in their rhythmic organization was observed the inner synchronization by period and acrophase. In the spectra of the rhythms of the studied parameters mainly was determined by only the annual harmonic with acrophase in the autumn months. It can together indicate the development of a powerful pathological process in the liver. PMID- 30284425 TI - [NERVOUS REGULATION OF BILIARY TRACT MOTILITY]. AB - Aim: The study of mechanisms of regulation of biliary tract motility by divisions of autonomic nervous system (ANS). Material and methods: Experiments were carried out on rabbits, chinchillas weighing 3.5-4 kg using gentle methods of treatment of experimental animals. Electromotor activity of electromotor (EMA) of the gallbladder and sphincter of Oddi was recorded. Irritation of the nerve produces an electrical pulse duration of 2 ms, the amplitude of 1.5-15 V, frequency of 10 Hz. Results: The mechanism of vagal inhibition of sphincter of Oddi motility and unidirectional stimulatory influence of ANS divisions on the motility of the gallbladder and sphincter of Oddi was studied. It was established that in the mechanism of vagal inhibition of sphincter of Oddi motility involved intramural adrenergic neurons synaptically connected with preganglionic parasympathetic fibers. At the stimulatory effect of vagus on biliary tract motility serotonergic intramural neurons are involved transmitting excitation to serotonin receptors of effector tissue.

AB - Aim: Develop a differential management at the patients with suspected sphincter of Oddi dysfunction after cholecystectomy. Materials and methods: 169 patients after cholecystectomy, divided into 2 groups. 1st group - 60 patients after repeated surgery formed as a comparison group. They multivariate analysis of clinical, laboratory and ultrasonic data revealed the most significant signs of organic causes of cholestasis, expressed in scores. 2nd group - 109 patients with a suspected sphincter of Oddi dysfunction, who did not have symptoms of organic pathology. Types of bile outflow were assessed by hepatobiliary scintigraphy (GBSG). In cases of doubtful diagnoses computer tomography, magnetic resonance cholangiopancreatography, and/or retrograde cholangiopancreatography are performed. Results: According to the scoring system, patients 1st group scored 4 or more (8,7 +/- 3,87) points. GBSG performed only in 7 (11.6%) patients, and in all cases the cholestatic type of bile outflow was detected. The amount of estimated points in the 2nd group was 2-3 points (2,43 +/- 0,34; p < 0.05). GBSG performed in all patients and three types of bile outflow were revealed: normal - in 21 (19.2%) patients, cholestatic in 8 (7.3%), and accelerated - in 80 (73.3%) patients. When refining the diagnosis in 10 (9%) patients had hidden organic disorders of bile outflow, served as an indication for surgery. Conclusion: Scoring system for the assessment of the suspected sphincter of Oddi dysfunction allows to differentiate of patients for invasive research and surgery. In our study group of 109 patients received less than 4 points, they have dominated the functional disorders, but the results of a detailed examination, 9% of patients had latent organic changes that have become indications for surgical treatment.

AB - In a review article considers issues of efficiency and tactics of the purpose of fat-soluble vitamins, as in cholestatic and noncholestatic liver disease, as well as water-soluble vitamins, particularly vitamin C cholelithiasis. Oxidative stress due to chronic inflammation is one of the major conversion mechanisms of liver fibrosis in cirrhosis. The imbalance between production of reactive oxygen species and antioxidant defense causes a number of pathophysiological changes in the liver, including activation of hepatic stellate cells. The carriers of the I148M PNPLA3 mutation was not observed concentration reduction in liver vitamin A with increasing severity of the disease, but the observed decrease in the level of circulating retinyl palmitate and retinol-binding protein. To the appointment of vitamin A in liver disease should be approached with caution. Hypervitaminosis A leads to accelerated liver fibrosis and stimulates carcinogenesis. Currently actively studied the possibility of using vitamin E as an antioxidant, in patients with non-alcoholic fatty liver disease. His presence in the membranes phospholipid bilayer allows cells to prevent non-enzymatic oxidation of cell components by free radicals. Vitamin E can suppress the profibrotic processes. In patients with chronic cholestatic liver disease is common, vitamin K deficiency, even when administered, and is associated with the degree of cholestasis and severity of disease. The vitamin D deficiency, liver disease is also associated with the severity of disease correlated with the severity of liver failure and infectious complications. Vitamin D is an independent prognostic parameter for mortality risk in patients with liver cirrhosis.

PMID- 30284434 TI - [STAGING SYSTEMS OF HEPATOCELLULAR CARCINOMA]. AB - It is the data of literature on existing classifications and systems of assessment and prognosis of hepatocellular carcinoma (HCC). In some classifications takes into account only the characteristics of the tumor tissue, in others are used biochemical and clinical characteristics in addition. Some systems allow to predict the survival of patients regardless of the stage of the disease, while others are most effective for the individual stages. The international TNM classification is generally accepted for the development of treatment methods and determining the forecast mainly for resectable HCC forms. The Japanese staging system (JIS) is mainly recommended for operable patients. Italian scale (CLIP), on the contrary, is intended to analyze HCC, which is not subject to surgical treatment. The Barcelona classification of liver cancer (BCLC) is considered the most universal, because it takes into account the stage of disease, the condition of the liver parenchyma and does not depend on the method of treatment and the patient's place of residence. Therefore, the choice of staging system and assessment of disease prognosis should be based on the clinical and morphological features of the disease, taking into account features of application of various scales.

PMID- 30284437 TI - Evaluation of Estrogenic Activity of Novel Bisphenol A Alternatives, Four Bioinspired Bisguaiacol F Specimens, by in Vitro Assays. AB - Alternatives to bisphenol A (BPA), such as lignin-inspired bisguaiacol F (BGF), are of interest for food contact materials due to increasing evidence of estrogenic activity (EA) and exposure-correlated harmful effects of BPA and its analogues. BGF has similar thermal and mechanical properties to BPA, but contains additional methoxy substituents that may significantly reduce its endocrine disruption potential. In this study, the EA of four BGF samples with different regioisomer ratios was quantified relative to 17beta-estradiol at ten concentrations by using two in vitro assays: MCF-7 cell proliferation and VM7Luc4E2 transactivation (TA). The results suggest BGF mixtures with higher molar ratios of p, p'-BGF and o, p'-BGF regioisomers exhibited lower EA than BPA, while BGF samples containing higher molar ratios of m, p'-BGF had no detectable EA over a wide range of test concentrations. These findings suggest the potential of BGF as a viable alternative to BPA for use in more environmentally friendly materials. PMID- 30284438 TI - Formation of Icephobic Surface with Micron-Scaled Hydrophobic Heterogeneity on Polyurethane Aerospace Coating. AB - Development of an anti-icing surface on a desired industrial coating patch/object has been the persistent challenge to several industries, such as aviation and wind power. For this aim, performing surface modification to implement the icephobic property on existing commercial coatings is important for practical applications. This work accomplishes an icephobic coating overlying a PPG aerospace polyurethane coating. It manifests a clear capability to delay the formation of frost as well as to reduce the adhesion strength of ice. This icephobic coating is sustained by a unique hydrophobic heterogeneity in the micron-scale of segregation, which is realized through solution casting of a specific copolymer consisting of random rigid and soft segments, namely poly(methyl methacrylate) and poly(lauryl methacrylate-2-hydroxy-3-(1-amino dodecyl)propyl methacrylate), respectively. A wrinkled pattern developed over the coating is observed because of the diverse traits between these two segments. Besides, the OH/NH groups of the soft segment are crosslinked by a diisocyanate monomer upon drying and curing to strengthen the coating. More importantly, integration of a small dose of paraffin wax into the copolymer induces a spread of soft microdomains on the winkled pattern surface. It is hypothesized that these dual heterogeneous assemblies are responsible for the icephobicity since they instigate distinct interactions with condensed water droplets. Lastly, the thermoelectric cooling (Peltier effect) and the adhesion strength of ice on the typical coatings were assessed. This investigation also includes examination on the icephobic durability of coating, which is enhanced when a small amount of polyethylene oligomer is incorporated into the coating. PMID- 30284439 TI - Application of C-Terminal 7-Azabicyclo[2.2.1]heptane to Stabilize beta-Strand like Extended Conformation of a Neighboring alpha-Amino Acid. AB - beta-Strands are formed by extended linear peptide chains that are usually paired to form beta-sheet structure through interstrand hydrogen bonding. Linking a structured organic molecule with alpha-amino acid(s) can enforce or stabilize beta-strand-like extended structures of the jointed amino acids. Spectroscopic and simulation studies indicated that the presence of a C-terminal 7 azabicyclo[2.2.1]heptane amine (Abh) favors a beta-strand-like extended conformation of the adjacent alpha-amino acid on the N side. The bridgehead substitution of the Abh unit biases the amide cis-trans equilibrium of the adjacent alpha-amino acid residue to cis conformation. The proximity, specified by the presence of bond paths (such as H-H bond path) between the bridgehead proton of Abh and the alpha-proton of the alpha-amino acid provides a driving force favoring the extended conformation, which is independent of solvents. These results provide a basis for de novo design of beta-strand-mimicking extended peptides by using beta-strand enforcer/stabilizer even in the absence of the interstrand hydrogen bonding. PMID- 30284440 TI - Acid-Interface Engineering of Carbon Nanotube/Elastomers with Enhanced Sensitivity for Stretchable Strain Sensors. AB - Stretchable strain sensors with high sensitivity or gauge factor (GF), large stretchability, and long-term durability are highly demanded in human motion detection, artificial intelligence, and electronic skins. Nevertheless, to develop high-sensitive sensors without sacrificing the stretchability cannot be realized using simple device configurations. In this work, an acid-interface engineering (AIE) method was proposed to develop a stretchable strain sensor with high GF and large stretchability. The AIE generates a layer of SiO x at the interface between the carbon nanotube (CNT) film and Ecoflex, playing a key role in enhancing the sensor's GF. Compared to devices without AIE (GF = 2.4), the ones with AIE are significantly improved. At an AIE time of 10 min, the GF up to 1665.9 is achieved without sacrificing the stretchability (>100%). The AIE generated cracks are found to modulate the electrical behaviors and enhance the GFs of sensors with AIE through the crack-induced rapid reduction in the electrical conduction pathway, which is manipulated by the CNTs bridging over the cracks. The device with AIE proves its high mechanical durability through a cycling test (>10 000 cycles) at a high strain up to ~80%, further paving its practical applications in various human motion detections.

The influence of pH on the stoichiometry and conditional association constants (log K) of the germanium complexes was investigated. UV-visible spectroscopy showed the successive formation of GePGG and Ge2PGG at pH 6.0 and of GePGG at pH 4.0. The results of the precipitation experiments indicated that germanium precipitation was influenced by organic solvents, pH values, the germanium/PGG ratio, and the presence of zinc. Acetone had the biggest effect on the solubility of these complexes, and lower pH values favored the precipitation of the complex. The results showed that a germanium/PGG ratio of more than 3:1 was essential for precipitation. Furthermore, the presence of zinc ions in the solution decreased the precipitation.

AB - Low-dimensional layered materials have attracted tremendous attentions because of their wide range of physical and chemical properties and potential applications in electronic devices. Using first-principles method taking into account the quasi-particle self-energy correction and Boltzmann transport theory, the electronic transport properties of the ZrSe3 monolayer are investigated, where the carrier relaxation time is accurately calculated within the framework of electron-phonon coupling. It is demonstrated that the high power factor of the monolayer can be attributed to the grooved bands near the conduction band minimum. Combined with the low lattice thermal conductivity obtained by solving the phonon Boltzmann transport equation, a considerable n-type ZT value of ~2.4 can be achieved at 800 K in the ZrSe3 monolayer.

AB - An artificial synaptic device with a continuous weight modulation behavior is fundamental to the hardware implementation of the bioinspired neuromorphic systems. Recent reported synaptic devices have a less number of conductance states, which is not beneficial for the continuous modulation of weights in neuromorphic computing. Preparing a device with as many conductance states as possible is of great significance to the development of brain-inspired neuromorphic computing. Here, we present a two-terminal flexible organic synaptic device with ultra-multimodulated conductance states, realizing a face recognition functionality with a strong error-tolerant nature for the first time. The device shows an excellent long-term potentiation or long-term depression behavior and reliability after 1000 folded destructive tests. There are 600 continuous ultra multimodulated conductance states, which can be used to realize the great face recognition capability. The recognition rates were 95.2% and above 90% for the initial and 15% noise pixel images, respectively. The strong error-tolerant nature indicates a potential application of a flexible organic artificial synaptic device with ultra-multimodulated conductance states in the large-scale neuromorphic systems.

AB - We describe the synthesis of alpha-alkynyl-beta-substituted cyclic ketones and analogue chromanones via one-pot Michael addition/hypervalent iodine-based alpha alkynylation. Cu(I)-catalyzed Michael addition using either alkyl-aluminum or Grignard reagents, followed by diastereoselective electrophilic alkynylation of the resulting enolate by 1-ethynyl-1lambda3,2-benziodoxol-3(1H)-one (EBX) resulted in the alpha-alkynyl-beta-substituted cyclic ketones or chromanones within 34-89% yield (16 examples). The reaction was successfully upscaled to the 5 mmol scale, and further functionalization of a model alkynylated ketone was demonstrated. PMID- 30284444 TI - Lesion Sensing during Initial Binding by Yeast XPC/Rad4: Toward Predicting Resistance to Nucleotide Excision Repair. AB - Nucleotide excision repair (NER) excises a variety of environmentally derived DNA lesions. However, NER efficiencies for structurally different DNA lesions can vary by orders of magnitude; yet the origin of this variance is poorly understood. Our goal is to develop computational strategies that predict and identify the most hazardous, repair-resistant lesions from the plethora of such adducts. In the present work, we are focusing on lesion recognition by the xeroderma pigmentosum C protein complex (XPC), the first and required step for the subsequent assembly of factors needed to produce successful NER. We have performed molecular dynamics simulations to characterize the initial binding of Rad4, the yeast orthologue of human XPC, to a library of 10 different lesion containing DNA duplexes derived from environmental carcinogens. These vary in lesion chemical structures and conformations in duplex DNA and exhibit a wide range of relative NER efficiencies from repair resistant to highly susceptible. We have determined a promising set of structural descriptors that characterize initial binding of Rad4 to lesions that are resistant to NER. Key initial binding requirements for successful recognition are absent in the repair-resistant cases: There is little or no duplex unwinding, very limited interaction between the beta hairpin domain 2 of Rad4 and the minor groove of the lesion-containing duplex, and no conformational capture of a base on the lesion partner strand. By contrast, these key binding features are present to different degrees in NER susceptible lesions and correlate to their relative NER efficiencies. Furthermore, we have gained molecular understanding of Rad4 initial binding as determined by the lesion structures in duplex DNA and how the initial binding relates to the repair efficiencies. The development of a computational strategy for identifying NER-resistant lesions is grounded in this molecular understanding of the lesion recognition mechanism. PMID- 30284446 TI - Characterization of Interactions and Phospholipid Transfer between Substrate Binding Proteins of the OmpC-Mla System. AB - The outer membrane (OM) of Gram-negative bacteria is a permeability barrier that impedes the entry of external insults, such as antibiotics and bile salts. This barrier function depends critically on the asymmetric lipid distribution across the bilayer, with lipopolysaccharides (LPS) facing outside and phospholipids (PLs) facing inside. In Escherichia coli, the OmpC-Mla system is believed to maintain OM lipid asymmetry by removing surface exposed PLs and shuttling them back to the inner membrane (IM). How proteins in the pathway interact to mediate PL transport across the periplasm is not known. Evidence for direct transfer of PLs between these proteins is also lacking. In this study, we mapped the interaction surfaces between the two PL-binding proteins, MlaC and MlaD, using site-specific in vivo photo-cross-linking, and obtained a physical picture for how these proteins may transfer PLs. Furthermore, we demonstrated using purified proteins that MlaD spontaneously transfers PLs to MlaC, suggesting that the latter has a higher affinity for PLs. Our work provides insights into the mechanism of bacterial intermembrane lipid transport important for the maintenance of OM lipid asymmetry.

AB - Maesil ( Prunus mume, green plum)-based products have been widely used in Asian cooking, which may contain amygdalin enzymatically converted to hydrogen cyanide after oral ingestion. In this study, the toxicity of Maesil syrups matured with and without Maesils was evaluated by focusing on relationship between amygdalin toxicity and its metabolic change. The cytotoxicity of amygdalin was highly related to its metabolites converted by beta-glucosidase, and the metabolic change was retarded in Maesil syrup. Toxicokinetics revealed extremely low oral absorption and short half-life of amygdalin standard and Maesil syrups, and delayed metabolic change of amygdalin in Maesil syrup was found. It seems that complex Maesil syrup components play roles against amygdalin degradation. Maesil syrup matured with Maesils had higher total polyphenols, lower amygdalin, and shorter half-life in bloodstream than Maesil syrup without Maesils, suggesting more safety benefit. No significant oral toxicity of Maesil syrups was found after 14-day repeated administration, implying their safety. PMID- 30284448 TI - Sequential Fractionation Strategy Identifies Three Missing Proteins in the Mitochondrial Proteome of Commonly Used Cell Lines. AB - Mitochondria are undeniably the cell powerhouse, directly affecting cell survival and fate. Growing evidence suggest that mitochondrial protein repertoire affects metabolic activity and plays an important role in determining cell proliferation/differentiation or quiescence shift. Consequently, the bioenergetic status of a cell is associated with the quality and abundance of the mitochondrial populations and proteomes. Mitochondrial morphology changes in the development of different cellular functions associated with metabolic switches. It is therefore reasonable to speculate that different cell lines do contain different mitochondrial-associated proteins, and the investigation of these pools may well represent a source for mining missing proteins (MPs). A very effective approach to increase the number of IDs through mass spectrometry consists of reducing the complexity of the biological samples by fractionation. The present study aims at investigating the mitochondrial proteome of five phenotypically different cell lines, possibly expressing some of the MPs, through an enrichment fractionation approach at the organelle and protein level. We demonstrate a substantial increase in the proteome coverage, which, in turn, increases the likelihood of detecting low abundant proteins, often falling in the category of MPs, and resulting, for the present study, in the identification of METTL12, FAM163A, and RGS13. All MS data have been deposited to the MassIVE data repository ( https://massive.ucsd.edu ) with the data set identifier MSV000082409 and PXD010446. PMID- 30284449 TI - Total Synthesis and Biological Evaluation of 19-Hydroxysarmentogenin-3 -O-alpha-l rhamnoside, Trewianin, and Their Aglycons. AB - Cardenolides comprise an important family of natural steroids with a wide spectrum of biological activities. Although 19-hydroxysarmentogenin-3- O-alpha-l rhamnoside (1a) and trewianin (1b) were structurally determined to have cardenolide structures, their biological activities have not been evaluated. The 6/6/6/5-membered ABCD-ring systems of both 1a and 1b are decorated by a beta oriented C17-butenolide, three C11,14,19-hydroxy groups, and a C3-O-l-rhamnoside moiety. On the other hand, 1a and 1b are epimeric at the C5-position. The structures of 1a and 1b were assembled from four simple fragments by applying a convergent and unified strategy. The AB-ring 10a/b and the D-ring 8/9 were tentatively tethered at the acetal moiety, and a subsequent stereoselective 6- exo radical reaction linked the two fragments. Next, an aldol reaction enabled simultaneous introduction of three new stereocenters of the C-rings of 5aa and 54. Attachment of the C17-butenolide led to aglycons 2a and 2b. l-Rhamnose was then installed into 2a and 2b to yield the targets 1a and 1b, respectively. Finally, the growth inhibitory activity of 1a, 1b, 2a, and 2b was assessed against MCF-7 human breast carcinoma cells. The significantly higher activities of 1a and 1b in comparison to 2a and 2b demonstrated the biological importance of the monosaccharide substructure. PMID- 30284450 TI - Flexible Laser-Induced Graphene for Nitrogen Sensing in Soil. AB - Flexible graphene electronics are rapidly gaining interest, but their widespread implementation has been impeded by challenges with ink preparation, ink printing, and postprint annealing processes. Laser-induced graphene (LIG) promises a facile alternative by creating flexible graphene electronics on polyimide substrates through the one-step laser writing fabrication method. Herein, we demonstrate the use of LIG, created with a low-cost UV laser, for electrochemical ion-selective sensing of plant-available nitrogen (i.e., both ammonium and nitrate ions: NH4+ and NO3-) in soil samples. The laser used to create the LIG was operated at distinct pulse widths (10, 20, 30, 40, and 50 ms) to maximize the LIG electrochemical reactivity. Results illustrated that a laser pulse width of 20 ms led to a high percentage of sp2 carbon (77%) and optimal peak oxidation current of 120 MUA during cyclic voltammetry of ferro/ferricyanide. Therefore, LIG electrodes created with a 20 ms pulse width were consequently functionalized with distinct ionophores specific to NH4+ (nonactin) or NO3- (tridodecylmethylammonium nitrate) within poly(vinyl chloride)-based membranes to create distinct solid contact ion-selective electrodes (SC-ISEs) for NH4+ and NO3- ion sensing, respectively. The LIG SC-ISEs displayed near Nernstian sensitivities of 51.7 +/- 7.8 mV/dec (NH4+) and -54.8 +/- 2.5 mV/dec (NO3-), detection limits of 28.2 +/- 25.0 MUM (NH4+) and 20.6 +/- 14.8 MUM (NO3-), low long-term drift of 0.93 mV/h (NH4+ sensors) and -5.3 MUV/h (NO3- sensors), and linear sensing ranges of 10-5 10-1 M for both sensors. Moreover, soil slurry sensing was performed, and recovery percentages of 96% and 95% were obtained for added NH4+ and NO3-, respectively. These results, combined with a facile fabrication that does not require metallic nanoparticle decoration, make these LIG electrochemical sensors appealing for a wide range of in-field or point-of-service applications for soil health management. PMID- 30284451 TI - The girl with the eyeball tattoo-what the ophthalmologist may expect? Case report and a review of literature. AB - INTRODUCTION: We report a case of patient who underwent bilateral eyeball tattoo procedure for cosmetic purpose complicated with intraocular dye injection which led to ocular inflammation, secondary glaucoma, and cataract. CASE DESCRIPTION: A 21-year-old female presented to emergency department with severe right eye pain and photophobia 21 days after conjunctival tattooing procedure. Slit-lamp examination revealed right-sided eyelid edema and black deposits of tattoo ink under the bulbar conjunctiva. Dye deposits were also present in anterior chamber, covering corneal endothelium, iris and anterior lens' capsule. Ocular inflammation and secondary glaucoma were diagnosed. The patient underwent surgical treatment to control ocular inflammation. Intraocular pressure remained stable after Nd:YAG iridotomy and on topical drugs. Moreover, during the follow up, in contralateral eye, we observed "conjunctival lumps"-local hypersensitivity reaction to the dye, which were asymptomatic to the patient. CONCLUSION: Eyeball tattooing complications are new challenges that ophthalmologist may have to face nowadays. We also reviewed for the first time possible complications of eyeball tattooing described in available literature. PMID- 30284452 TI - Vitrectorhexis in penetrating eye injuries in adults. AB - INTRODUCTION: Vitrectorhexis is an alternative for manual continuous curvilinear capsulorhexis originally developed for paediatric cataract surgery. The aim of our study was the evaluation of the technique in adult patients with penetrating ocular injury and traumatic cataracts. METHODS: Eight eyes of 8 patients (23-41 years, all males) had penetrating mechanical corneal trauma. Anterior lens capsule was penetrated in all cases and additional posterior capsule defect in five cases. Intraocular foreign body was detected in one case in the crystalline lens and in two cases in the posterior segment. Standard 23G infusion cannula and vitreous cutter were applied to perform anterior capsule opening, removal of lens material, anterior vitrectomy and pars plana vitrectomy if needed. No phacoemulsification or irrigation/aspiration probe was used. RESULTS: Vitrectorhexis could be performed in 7 out of 8 cases with the preservation of peripheral anterior capsule; primary implantation of posterior chamber intraocular lens was possible in all cases (in the bag in three eyes and into the sulcus in five eyes). Anterior chamber was stable in all cases intraoperatively, and no dropped nucleus or lens fragment loss was observed. Surgery was combined with pars plana vitrectomy in three cases, with foreign body removal (when necessary). No postoperative complication occurred. CONCLUSION: Vitrectorhexis was found to be an effective and safe alternative method in the management of complex anterior segment trauma cases. With its use, traditional cataract surgical devices can be substituted and additional benefits of vitreous cutter can be utilized in selected cases, especially in young adults. PMID- 30284453 TI - Evaluation of static and dynamic pupil characteristics in hyperopic anisometropic amblyopia. AB - PURPOSE: The aim of this study is to perform a comparison of static and dynamic pupillometry measurements in patients with hyperopic anisometropic amblyopia and age-matched controls. METHODS: This prospective cross-sectional study consisted of 38 patients with hyperopic anisometropic amblyopia and 80 control subjects. A quantitative pupillometry system was used to evaluate the pupil characteristics of higher hyperopic eyes (Group 1), the fellow eyes (Group 2), and healthy eyes (Group 3). Static pupillometry measurements were taken including scotopic pupil diameter, mesopic pupil diameter, low-photopic pupil diameter, and high-photopic pupil diameter. Subsequently, dynamic pupillometry measurements were taken including resting diameter, amplitude of pupil contraction, latency of pupil contraction, duration of pupil contraction, velocity of pupil contraction, latency of pupil dilation, duration of pupil dilation, and velocity of pupil dilation. RESULTS: Groups 1 and 2 had statistically significantly lower scotopic and high-photopic pupil diameter values compared with Group 3 (p < 0.05). The amplitude of pupil contraction values were also statistically significantly lower in Groups 1 and 2 compared with Group 3 (p = 0.001 and p = 0.003). However, there were no significant differences between the study and the control eyes with respect to mesopic and high-photopic pupil diameter, resting diameter, latency of pupil contraction, duration of pupil contraction, velocity of pupil contraction, latency of pupil dilation, duration of pupil dilation, and velocity of pupil dilation values (p > 0.05, for all). CONCLUSION: Static and dynamic pupil characteristics of higher hyperopic eyes and their fellow eyes are similar. This may support that amblyopia is not a monocular disorder, but can affect both eyes. PMID- 30284454 TI - Associations of objective versus subjective social isolation with sleep disturbance, depression, and fatigue in community-dwelling older adults. AB - OBJECTIVE: Older adults are at higher risk of experiencing social isolation, which has been linked to impaired physical and mental health. The link between social isolation and health might be due to objective deprivation of social network and/or subjective experience of loneliness. This community-based cross sectional study examined whether the associations between social isolation and behavioral symptoms including sleep disturbance, depression, and fatigue are mostly explained by its subjective component. METHODS: Randomly selected 2541 community-dwelling individuals in Los Angeles aged >=60 years were telephone interviewed regarding their objective and subjective social isolation (respectively social network size and loneliness), sleep disturbance, depression, and fatigue. RESULTS: When objective and subjective social isolation were separately included in multivariate regression models, both were significantly associated with behavioral symptoms. However, once they were simultaneously included in the same multivariate models, while subjective social isolation remained strongly associated (adjusted beta 0.24 for sleep disturbance [P < 0.001], 0.44 for depression [P < 0.001], 0.17 for fatigue [P < 0.001]), objective social isolation was weakly or non-significantly associated (-0.04 for sleep disturbance [P = 0.03], -0.01 for depression [P = 0.48], -0.003 for fatigue [P = 0.89]). Additionally, those with objective social isolation were found to have worse symptoms mostly when they also experienced subjective social isolation. CONCLUSIONS: Older adults with objective social isolation may experience sleep disturbance, depression, and fatigue because they feel socially isolated, not just because they are deprived of social networks. Interventions that target social isolation might serve as potential treatments for improving behavioral health of older adults, especially by targeting its subjective component. PMID- 30284455 TI - A Prospective Study on the Safety and Effectiveness of a Composite Sinus Stent for Use After Endoscopic Sinus Surgery. AB - Background The composite sinus stent was developed to support the nasal walls, stabilize the middle turbinate, and prevent adhesions following endoscopic sinus surgery (ESS). Objective This study sought to assess its safety and effectiveness. Methods A prospective clinical trial was conducted in a single medical center in 2016-2018. The study included 30 patients (64% males) with a mean age of 41.9 years, who were scheduled for bilateral ESS, were randomized to undergo composite sinus stent implantation for 14 to 28 days or middle meatus placement of a Telfa tampon for 2 to 3 days. Telfa is a nonadherent absorbent dressing that has been compared favorably with other packs for use following ESS. Both groups received the same postoperative treatment. Outcomes were evaluated endoscopically by the principal investigator and also by an independent investigator blinded to the intervention the patient had and by self-report questionnaires at 3 and 12 weeks postoperatively. Results The stent was successfully implanted and removed in all 29 treated sinuses, without complications. None of the stents showed granulation tissue or crusting. Compared to the tampon group, the stent group had significantly less inflammation (mean visual analog scale scores 0.2 vs 4.2 at 12 weeks, P = .01). The probability of having adhesion was 9.3 times greater in the control group compared to the study group ( P = .026), and middle turbinate lateralization rate at 12 weeks was 3.8% versus 44% in the study group and the control group, respectively, at 12 weeks ( P = .006). Patients who underwent stent implantation experienced higher symptomatic improvement (Sino-Nasal Outcome Test 22 of -37.13 vs -28.07, P = .01, in study and control groups, respectively). During stent implantation (2-4 weeks), patients did not suffer from any discomfort. Conclusions The composite sinus stent is safer and more effective than the Telfa tampon in maintaining sinus cavity patency and promoting healing following ESS. PMID- 30284456 TI - Evaluation of ocular motility deviation changes in exotropic patients after cycloplegic eye drops versus prism adaptation test. AB - PURPOSE: To evaluate changes in ocular motility deviation with cycloplegic eye drop examination compared to the prism adaptation test in patients with strabismus. METHODS: The medical charts were reviewed of all patients who underwent primary strabismus surgery in our center from December 2013 to July 2015. Data collected included demographics, medical history, and findings on pre operative ophthalmic/orthoptic examination. Ocular motility deviation was measured before instillation of cycloplegic eye drops, immediately after maximal dilation (end point), and 10 and 20 min later. Prism adaptation test readings were taken at baseline, immediately after prism removal (end point), and 10 and 20 min later. RESULTS: A total of 43 patients had complete pre- and post operative evaluations. Our analysis focused only on the exotropic patients (n = 33). On cycloplegics, there was no significant difference in ocular motility deviation between baseline and end point for distance and near (p = 0.584, p = 0.468, respectively). On prism adaptation test, comparison of ocular motility deviation between baseline and end point was statistically significant for distance and near (p = 0.002, p = 0.001, respectively). Changes remained significant 10 min after the end point for near (p = 0.011). Comparison at the end points between the tests revealed statistical significance for distance and near, favoring the prism adaptation test (p = 0.001 and p < 0.001, respectively). This significance was maintained even after 10 min for near (p = 0.036). CONCLUSION: The prism adaptation test is preferred over cycloplegic eye drops for the evaluation of maximal reserve of distance/near motility before surgical correction of exotropia. PMID- 30284457 TI - Qualitative Evaluation of High School Implementation Strategies for Youth Sports Concussion Laws. AB - CONTEXT: : All 50 states and the District of Columbia have enacted laws governing concussion management and education. These concussion laws, featuring common tenets regarding removal from play, return to play, and concussion education, have shaped school and district policies. OBJECTIVE: : To evaluate the strategies commonly used to implement concussion laws at the school and district levels, as reported by certified athletic trainers (ATs). DESIGN: : Qualitative study. SETTING: : High schools. PATIENTS OR OTHER PARTICIPANTS: : We interviewed 64 ATs from high schools (1 per school) participating in High School Reporting Information Online. DATA COLLECTION AND ANALYSIS: : Interviews were conducted with participants between April and October 2015 regarding implementation of the 3 core tenets of concussion laws. Research team members independently evaluated the interview transcripts and field notes to identify common themes in implementation strategies. RESULTS: : Of the 64 schools represented, 90.6% were public schools, 89.1% sponsored more than 15 sports, and all schools employed at least 1 AT and had a written concussion policy. Four commonly used strategies to implement removal from play were reliance on coaches, immediate response, referral and guidance after injury, and notification of key individuals. Use of assessment or baseline tests, communication among parties involved, reliance on AT assessments, and return-to-learn policies were 4 frequent strategies to implement return to play. Finally, 3 major implementation strategies to effectuate concussion education were use of existing educational tools, timing of education, and concussion training for school professionals. CONCLUSIONS: : Although concussion laws were passed at different times and varied in content across states, common themes in implementation strategies emerged across jurisdictions. The identification of strategic approaches to implementation will help ensure proper concussion management and education, reducing negative health outcomes among youths with concussions. PMID- 30284458 TI - Epidemiology of Injuries Requiring Emergency Transport Among Collegiate and High School Student-Athletes. AB - CONTEXT: : Data regarding the epidemiology of emergency-transport incidents (ETIs) of patients with sport-related injuries are lacking. Understanding the use of emergency services by athletic trainers can help improve emergency preparedness and prehospital care for injured student-athletes. OBJECTIVE: : To determine the frequencies and types of ETIs resulting from athletic participation. DESIGN: : Descriptive epidemiology study. SETTING: : Participating colleges and high schools during 2009-2010 to 2014-2015 and 2011-2012 to 2013 2014, respectively. PATIENTS OR OTHER PARTICIPANTS: : Student-athletes in 23 high school and 25 intercollegiate sports. MAIN OUTCOME MEASURE(S): : Data on injuries requiring emergency transport were collected by each team's athletic trainer via their respective online injury-tracking software. Athletic trainers also collected data on athlete-exposures (AEs). Emergency-transport incident frequencies and injury rates per 10 000 AEs with 95% confidence intervals (CIs) were reported. For each ETI, the sport, body part, injury mechanism, and final diagnosis were recorded. RESULTS: : A total of 339 and 146 ETIs were reported in collegiate and high school players, respectively. Collegiate women's ice hockey had the highest ETI rate (1.28/10 000 AEs; 95% CI = 0.71, 1.86). In high school, football had the highest rate at 0.80 per 10 000 AEs (95% CI = 0.64, 0.97). Athletes with head or face injuries required the most transports in college (n = 71, 20.9%) and high school (n = 33, 22.6%) across all sports. Strains (n = 50, 14.7%) and fractures (n = 35, 24.0%) were the leading diagnoses for patients undergoing transport in college and high school, respectively. CONCLUSIONS: : Athletic trainers should maintain a high level of emergency preparedness when working with sports that have high rates and numbers of ETIs. Athletes with injuries to the head/face required the most frequent transport across competition levels. Athletic trainers should have the appropriate equipment and protocols in place to handle these patients. Future researchers should examine the differences between field and hospital diagnoses to help improve prehospital care and decrease the likelihood of unnecessary emergency transports. PMID- 30284459 TI - Effects of Xiaoshuan Enteric-Coated Capsule on White and Gray Matter Injury Evaluated by Diffusion Tensor Imaging in Ischemic Stroke. AB - Xiaoshuan enteric-coated capsule (XSECC) is a drug approved by the Chinese State Food and Drug Administration for the treatment of stroke. This study was to investigate the effects of XSECC on white and gray matter injury in a rat model of ischemic stroke by diffusion tensor imaging (DTI) and histopathological analyses. The ischemia was induced by middle cerebral artery occlusion (MCAO). The cerebral blood flow measured by arterial spin labeling was improved by treatment with XSECC on the 3rd, 7th, 14th and 30th days after MCAO. Spatiotemporal white and gray matter changes in MCAO rats were examined with DTI derived parameters (fractional anisotropy, FA; apparent diffusion coefficient, ADC; axial diffusivity, lambda//; radial diffusivity, lambda?). The increased FA was found in the XSECC treatment group in the corpus callosum, external capsule and internal capsule, linked with the decreased lambda//, lambda? and ADC on the 3rd day and reduced ADC on the 30th day in the external capsule, suggesting XSECC reduced the axon and myelin damage in white matter after stroke. The relative FA in the striatum, cortex and thalamus in XSECC treatment group was significantly increased on the 3rd, 7th, 14th and 30th days accompanied by the increased lambda// on the 3rd day and reduced relative ADC and lambda? on the 30th day, indicating that XSECC attenuated cell swelling and membrane damage in the early stage and tissue liquefaction necrosis in the late stage in gray matter after stroke. Additionally, XSECC-treated rats exhibited increased mean fiber length assessed by diffusion tensor tractography. Moreover, histopathological analyses provided evidence that XSECC relieved nerve cell and myelin damage in white and gray matter after stroke. Our research reveals that XSECC could alleviate white and gray matter injury, especially reducing nerve cell damage and promoting the repair of axon and myelin after ischemic stroke. PMID- 30284460 TI - Neuroprotective Action of Human Wharton's Jelly-Derived Mesenchymal Stromal Cell Transplants in a Rodent Model of Stroke. AB - Wharton's jelly-derived mesenchymal stromal cells (WJ-MSCs) have distinct immunomodulatory and protective effects against kidney, liver, or heart injury. Limited studies have shown that WJ-MSCs attenuates oxygen-glucose deprivation mediated inflammation in hippocampal slices. The neuroprotective effect of intracerebral WJ-MSC transplantation against stroke has not been well characterized. The purpose of this study was to examine the neuroprotective effect of human WJ-MSC (hWJ-MSC) transplants in an animal model of stroke. Adult male Sprague-Dawley rats were anesthetized and placed in a stereotaxic frame. hWJ MSCs, pre-labeled with chloromethyl benzamide 1,1'-dioctadecyl-3,3,3'3'- tetramethylindocarbocyanine perchlorate (CM-Dil), were transplanted to the right cerebral cortex at 10 min before a transient (60 min) right middle cerebral artery occlusion (MCAo). Transplantation of hWJ-MSCs significantly reduced neurological deficits at 3 and 5 days after MCAo. hWJ-MSC transplants also significantly reduced brain infarction and microglia activation in the penumbra. Grafted cells carrying CM-Dil fluorescence were identified at the grafted site in the ischemic core; these cells were mostly incorporated into ionized calcium binding adaptor molecule (+) cells, suggesting these xenograft cells were immuno rejected by the host. In another set of animals, hWJ-MSCs were transplanted in cyclosporine (CsA)-treated rats. hWJ-MSC transplants significantly reduced brain infarction, improved neurological function, and reduced neuroinflammation. Less phagocytosis of CM-dil-labeled grafted cells was found in the host brain after CsA treatment. Transplantation of hWJ-MSC significantly increased glia cell line derived neurotrophic factor expression in the host brain. Taken together, our data support that intracerebral transplantation of hWJ-MSCs reduced neurodegeneration and inflammation in the stroke brain. The protective effect did not depend on the survival of grafted cells but may be indirectly mediated through the production of protective trophic factors from the transplants. PMID- 30284461 TI - Sophora flavescens Containing-QYJD Formula Activates Nrf2 Anti-Oxidant Response, Blocks Cellular Transformation and Protects Against DSS-Induced Colitis in Mouse Model. AB - Qu-Yu-Jie-Du decoction (QYJD) is a commercially available traditional Chinese medicine (TCM). It is an aqueous extract of a Chinese herbal formula primarily consisting of eight TCM herbs: Taraxacum campylodes G.E. Haglund, Coix lacryma jobi L., Smilax glabra Roxb., Sanguisorba officinalis L, Styphnolobium japonicum (L.) Schott, Prunus persica (L.) Batsch, Sophora flavescens Aiton, and Eupolyphaga sinensis Walker. Matrine and oxymatrine are two of the major phytochemical constituents of QYJD. Inflammation and oxidative stress are strongly associated with colon carcinogenesis. Colorectal cancer (CRC) is the third most common type of cancer. Therefore, cancer chemopreventive agents targeting CRC are urgently needed. This study was conducted to investigate the potential anticancer effects and the underlying mechanisms of QYJD and its active constituents, matrine and oxymatrine, in human colon cancer HT29 cells and in a dextran sulfate sodium (DSS)-induced colitis mouse model. QYJD and matrine effectively inhibited the proliferation and anchorage-independent growth of HT29 cells in a dose-dependent manner. QYJD and matrine also induced an Nrf2-mediated anti-oxidant response element-luciferase activity and upregulated the Nrf2 mediated anti-oxidative stress genes HO-1 and NQO1 at both the mRNA and protein levels. In the DSS-induced colitis mouse model, QYJD reduced the disease activity index (DAI) and alleviated colonic shortening. Elevated Nrf2 and HO-1 mRNA levels were also observed in QYJD-treated mice. These findings showed that QYJD could elicit anti-inflammatory and anti-oxidative stress response in vitro in a cell line and in vivo in a DSS-induced colitis mouse model. These responses may contribute to the overall anticolon cancer effect of QYJD. PMID- 30284462 TI - Therapeutic Potential of Naringin for Intervertebral Disc Degeneration: Involvement of Autophagy Against Oxidative Stress-Induced Apoptosis in Nucleus Pulposus Cells. AB - Intervertebral disc degeneration (IDD) is a major cause of lower back pain, but few efficacious medicines have been developed for IDD. Increased nucleus pulposus cells apoptosis is a dominant pathogenesis of IDD and is considered a therapeutic target. Previously, our group proved that autophagy may protect nucleus pulposus cells against apoptosis. As one of the major bioflavonoids of citrus, naringin activates autophagy. Therefore, we hypothesize that naringin may have therapeutic potential for IDD by activating autophagy in nucleus pulposus cells. In this study, we evaluated the effects of naringin on TBHP-induced oxidative stress in nucleus pulposus cells in vitro as well as in puncture-induced rat IDD model in vivo. Our results showed that naringin could reduce the incidence of oxidative stress-induced apoptosis in nucleus pulposus cells and promoted the expression of autophagy markers LC3-II/I and beclin-1. Meanwhile, inhibition of autophagy by 3 MA may partially reverse the anti-apoptotic effect of naringin, indicating that autophagy was involved in the protective effect of naringin in nucleus pulposus cells. Further study showed that autophagy regulation of naringin may be related to AMPK signaling. Also, we found that naringin treatment can regulate the expression of collagen II, aggrecan and Mmp13 to sustain the extracellular matrix. Furthermore, our in vivo study showed that naringin can ameliorate IDD in puncture-induced rat model. In conclusion, our study suggests that naringin can protect nucleus pulposus cells against apoptosis and ameliorate IDD in vivo, the mechanism may relate to its autophagy regulation. PMID- 30284463 TI - Progress in Experimental and Clinical Research of the Diabetic Retinopathy Treatment Using Traditional Chinese Medicine. AB - Diabetic retinopathy (DR), one of the most common microvascular complications of diabetic mellitus, is currently the main cause of adult-acquired blindness. The pathogenesis of DR is complex and the current clinical application of various treatment methods cannot completely prevent the development of this disease. Many reports have been published regarding the treatment of DR with Traditional Chinese Medicine (TCM), which has received increasing attention from medical practitioners worldwide. Studies published between 1994 and April 2017 were collected from the CNKI, VIP, Medline and Web of Science databases, as well as from Chinese traditional books and Chinese Pharmacopoeia, subsequently obtaining more than 550 studies. Thereafter, the status quo of DR treatment using TCM had been summarized according to four aspects - compound formula therapy, Chinese herbal medicine extracts and monomer therapy, integrated traditional Chinese and Western medicine therapy, and Chinese medicine external treatment. According to the literature reviewed herein, TCM has had definite effects on the prevention and treatment of DR, especially when used in combination with modern medical methods. However, the lack of a unified standard on the syndrome differentiation of DR and the lack of support of evidence-based medicine theory in clinical practice have been consistent concerns in previous research studies and needs to be addressed in subsequent studies. PMID- 30284464 TI - Chinese Herbal Medicine Glycyrrhiza inflataReduces Abeta Aggregation and Exerts Neuroprotection through Anti-Oxidation and Anti-Inflammation. AB - Amyloid [Formula: see text] (A[Formula: see text]) plays a major role in the pathogenesis of Alzheimer's disease (AD). The accumulation of misfolded A[Formula: see text] causes oxidative and inflammatory damage leading to apoptotic cell death. Chinese herbal medicine (CHM) has been widely used in clinical practice to treat neurodegenerative diseases associated with oxidative stress and neuroinflammation. This study examined the neuroprotection effects of CHM extract Glycyrrhiza inflata (G. inflata) and its active constituents, licochalcone A and liquiritigenin in AD. We examined A[Formula: see text] aggregation inhibition, anti-oxidation and neuroprotection in Tet-On A[Formula: see text]-GFP 293/SH-SY5Y cells and anti-inflammatory potential in lipopolysaccharide (LPS)-stimulated RAW 264.7 and LPS and interferon (IFN) [Formula: see text] (LPS/IFN-[Formula: see text])-activated BV-2 cells. In addition, we applied conditioned media (CM) of BV-2 cells primed with LPS/IFN [Formula: see text] to A[Formula: see text]-GFP SH-SY5Y cells to uncover the neuroprotective mechanisms. Our results showed that G. inflata extract and its two constituents displayed potentials of A[Formula: see text] aggregation inhibition and radical-scavenging in biochemical assays, A[Formula: see text] misfolding inhibition and reactive oxygen species (ROS) reduction in A[Formula: see text]-GFP 293 cells, as well as neurite outgrowth promotion, acetylcholinesterase inhibition and SOD2 up-regulation in A[Formula: see text] GFP SH-SY5Y cells. Meanwhile, both G. inflata extract and its constituents suppressed NO, TNF-[Formula: see text], IL-1[Formula: see text], PGE2 and/or Iba1 productions in inflammation-stimulated RAW 264.7 or BV-2 cells. G. inflata extract and its constituents further protected A[Formula: see text]-GFP SH-SY5Y cells from BV-2 CM-induced cell death by ameliorating reduced BCL2 and attenuating increased IGFBP2, cleaved CASP3, BAD and BAX. Collectively, G. inflata extract, licochalcone A and liquiritigenin display neuroprotection through exerting anti-oxidative and anti-inflammatory activities to suppress neuronal apoptosis. PMID- 30284465 TI - Modified Ginseng Extract Induces Apoptosis in HepG2 Cancer Cells by Blocking the CXCL8-Mediated Akt/Nuclear Factor-[Formula: see text]B Signaling Pathway. AB - The cytokine C-X-C motif chemokine ligand 8 (CXCL8) is produced in the tumor microenvironment and has an important role in cancer pathogenesis. CXCL8 activates the nuclear factor (NF)-[Formula: see text]B signaling. However, the role of NF-[Formula: see text]B inactivation in apoptosis induced by negative regulation of CXCL8 remains unclear. Here, we assessed the effects of MRGX on the transcriptional activity of NF-[Formula: see text]B and the expression of tumor necrosis factor (TNF)-[Formula: see text]-stimulated target genes in liver cancer cells. Furthermore, we found that modified regular ginseng extract (MRGX) mediated inhibition of NF-[Formula: see text]B signaling induced apoptosis. Importantly, MRGX exerted strong activity, inhibiting TNF-[Formula: see text] induced expression of Akt and NF-[Formula: see text]B in a concentration dependent manner. Furthermore, MRGX inhibited the TNF-[Formula: see text]-induced expression of genes encoding CXCL8, CXCL1, inducible nitric oxide synthase and intercellular adhesion molecule 1. MRGX also dowregulated Akt activation, and there was a significant decrease in Akt activation in HepG2 cells treated with CXCL8 siRNA. Conversely, CXCL8 overexpression increased Akt activation in MRGX treated HepG2 cells. When Akt was silenced, MRGX treatment of HepG2 cells overexpressing CXCL8 decreased nuclear translocation of NF-[Formula: see text]B, whereas Akt overexpression increased nuclear translocation of NF-[Formula: see text]B in MRGX-treated HepG2 cells. Moreover, MRGX negatively regulated the TNF [Formula: see text]-mediated I[Formula: see text]B/NF-[Formula: see text]B pathway to promote Bax activation, resulting in caspase-3 activation and apoptosis. Taken together, these results indicated that MRGX inhibited CXCL8 mediated Akt/NF-[Formula: see text]B signaling, which upregulated Bax activation and consequently induced apoptosis in HepG2 cells. PMID- 30284466 TI - Activity Dependent Mammalian Target of Rapamycin Pathway and Brain Derived Neurotrophic Factor Release Is Required for the Rapid Antidepressant Effects of Puerarin. AB - Puerarin is a traditional Chinese medicine with beneficial effects of reduced depression-like behaviors in mice with stress. Previous studies also show that puerarin can produce neuroprotective effect via activating the Akt or increased brain-derived neurotrophic factor (BDNF) expression. Interestingly, BDNF and Akt downstream target, mammalian target of rapamycin (mTOR) mediate the fast-acting antidepressant properties of ketamine. Until now, the involvement of the mTOR signaling pathway or BDNF on puerarin-induced antidepressant effect remains unknown. We aimed to investigate whether the antidepressant-like effect induced by puerarin would associate mTOR signaling pathway and BDNF release. The antidepressant-like effects of puerarin were evaluated using the forced swim test. The activation of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionaic acid receptor (AMPAR)-mTOR signaling pathway and release of BDNF in the prefrontal cortex were determined. We also investigated the effect of puerarin on AMPAR trafficking through measuring the PKA phosphorylation of AMPAR subunit GluR1. Our present results show that puerarin exerted antidepressant-like responses that was mediated by AMPAR-induced mTOR signaling pathway and associated with increased BDNF release. Moreover, a significant increase in the GluR1 phosphorylation at its PKA site was noted following puerarin treatment. Our findings are the first to demonstrate that the antidepressant-like actions of puerarin require AMPAR mTOR signaling pathway activation, are associated with an increased BDNF level and facilitate AMPAR membrane insertion. These findings provide preclinical evidence that puerarin may possess antidepressant property which is mediated by the glutamatergic system. PMID- 30284467 TI - Antidepressant Effects of Vaccinium bracteatum via Protection Against Hydrogen Peroxide-Induced Oxidative Stress and Apoptosis. AB - The present study evaluates the anti-oxidative stress activity of Vaccinium bracteatum Thunb. fruit extract (VBFW) to identify the mechanisms responsible for its antidepressant-like effects. To evaluate the antidepressant and anti-oxidant effects of VBFW, malondialdehyde (MDA), serotonin transporter (SERT), and monoamine oxidase A (MAO-A) levels were measured in a mouse model of chronic restraint stress (CRS). The underlying mechanisms preventing oxidative stress and neuronal apoptosis were investigated using in vitro models of hydrogen peroxide (H2O[Formula: see text]-induced neuronal damage. The results showed that VBFW treatment (200[Formula: see text]mg/kg) significantly reduced MDA, SERT, and MAO A levels in the prefrontal cortex of CRS mice. Furthermore, VBFW (30[Formula: see text][Formula: see text]g/mL) exhibited protective effects against H2O2-induced cell death via inhibition of the H2O2-induced increase in Bax and decrease in Bcl 2 levels within the mitochondria of SH-SY5Y cells. Furthermore, VBFW (10 and 30[Formula: see text][Formula: see text]g/mL) exerted protective effects against H2O2-induced cell death through inhibition of key mitochondria-associated apoptotic proteins such as cytochrome c, caspase-3 and PARP. Additionally, VBFW (10 and 30[Formula: see text][Formula: see text]g/mL) could improve the activity of anti-oxidant enzymes (such as SOD and catalase) in H2O2-treated SH-SY5Y cells. These results suggest that the antidepressant and anti-oxidant effects of VBFW might be mediated by the regulation of SERT and MAO-A, and possibly associated with regulation of oxidative stress-induced apoptosis. PMID- 30284468 TI - Allyl Isothiocyanate Induces Autophagy through the Up-Regulation of Beclin-1 in Human Prostate Cancer Cells. AB - Allyl isothiocyanate (AITC), one of the most widely studied phytochemicals, inhibits the survival of human prostate cancer cells while minimally affecting normal prostate epithelial cells. Our study demonstrates the mechanism of AITC induced cell death in prostate cancer cells. AITC induces autophagy in RV1 and PC3 cells, judging from the increased level of LC3-II protein in a dose- and time dependent manner, but not in the normal prostate epithelial cell (PrEC). Inhibition of autophagy in AITC-treated cells decreased cell viability and enhanced apoptosis, suggesting that the autophagy played a protective role. There are several pathways activated in ATIC-treated cells. We detected the phosphorylation forms of mTOR, ERK, AMPK, JNK and p38, and ERK AMPK and JNK activation were also detected. However, inhibition of AITC-activated ERK, AMPK and JNK by pre-treatment of specific inhibitors did not alter autophagy induction. Finally, increased beclin-1 expression was detected in AITC-treated cells, and inhibition of AITC-induced beclin-1 attanuated autophagy induction, indicating that AITC-induced autophagy occurs through upregulating beclin-1. Overall, our data show for the first time that AITC induces protective autophagy in Rv1 and PC3 cells through upregulation of beclin-1. Our results could potentially contribute to a therapeutic application of AITC in prostate cancer patients. PMID- 30284469 TI - Regulating Gut Flora Dysbiosis in Obese Mice by Electroacupuncture. AB - Recently, gut flora has been linked to the onset of obesity and has been shown to influence the host's metabolism. Acupuncture is a well-known agent used for the treatment of numerous diseases such as obesity. This study aimed to explore the impacts of electroacupuncture treatment on gut microbiota composition and function in obese mice. Pyrosequencing of 16S rRNA genes and Metagenomic analysis of the fecal microbiota were used for this purpose. The basic parameters of body weight, Lee's index, serum lipid and epididymal adipose weight were ameliorated significantly after introducing an electroacupuncture intervention. Acidobacteria, Cyanobacteria and Basidiomycota (Normal group) and Fusobacteria, Firmicutes and Spirochmycetes (Model group) were remarkably affluent at the phylum level. Bacteroides sp. CAG: 927 and Prevotella sp. CAG: 1031 (Normal group), Lachnospiraceae bacterium and Helicobacter rodentium (Model group) at the species level were distinctly enriched. The structures and functions of the intestinal flora were significantly different between healthy and obese mice, and animals in the acupuncture group gradually tended towards healthy controls. Moreover, electroacupuncture altered the bacterial diversity and metabolic genes to establish new balance, observed the obvious change from 7[Formula: see text]d and stabilized gradually through 21[Formula: see text]d. These findings suggested gut flora could be a novel target of electroacupuncture treatment against obesity. PMID- 30284470 TI - Marsdenia tenacissima: A Review of Traditional Uses, Phytochemistry and Pharmacology. AB - The stems and roots of Marsdenia tenacissima (Roxb.) Wight et Arn., a traditional Chinese medicine and Dai herbal medicine, have been widely used for the treatment of asthma, trachitis, tonsillitis, pharyngitis, cystitis, pneumonia and drug or food poisoning. Nowadays, the extract of Marsdenia tenacissima, under the trademark of "Xiao-ai-ping", is widely used in clinic for the treatment of different cancers in China. To date, approximately 196 chemical ingredients covering steroids, triterpenes and organic acids have been identified from different parts of this plant. Steroids are the major characteristic and bioactive constituents of this plant. Modern pharmacology has demonstrated that the crude extracts and steroids have various in vitro and in vivo pharmacological activities, such as multidrug resistance reversal, antitumor, anti-angiogenic, immunomodulation and anti-HIV activities. The multidrug resistance reversal of steroids provided evidence for the use of this herb in clinic. However, despite wide clinical application, clinical trials, quality control method, pharmacokinetic and toxicity research on Marsdenia tenacissima were seldom reported and deserved further efforts. The present review aimed to achieve a comprehensive and up-to-date investigation in ethnopharmacology, phytochemistry, pharmacology, clinical study, pharmacokinetics, toxicology and quality control of Marsdenia tenacissima. In addition, the possible perspectives and trends for future studies of Marsdenia tenacissima have also been put forward. It is believed that this review would provide a theoretical basis and valuable data for future in-depth studies and applications. PMID- 30284472 TI - Surgical closure of giant traumatic macular hole with retinal graft. AB - AIM: To present a case with a large traumatic macular hole that we repaired with a retinal graft. CASE DESCRIPTION: A 24-year-old male patient presented with corneal penetration and an intraocular foreign body caused by a work accident. Vitrectomy and intraocular foreign body removal were performed. One month after the surgery, the patient had macula on retinal detachment in the nasal and superior quadrant. In addition, a giant macular hole was formed. However, the macula was atrophic because of the trauma, and we could not repair the hole with classic macular hole surgery techniques. For this reason, we used a retinal graft to cover the macular hole, and we observed that the hole was closed in follow-up visits. CONCLUSION: Retinal grafts can be used in patients with giant macular holes. They may be useful especially in patients with atrophic macula in trauma cases.

AB - The SLX4/FANCP tumor suppressor has emerged as a key player in the maintenance of genome stability, making pivotal contributions to the repair of interstrand cross links, homologous recombination, and in response to replication stress genome wide as well as at specific loci such as common fragile sites and telomeres. SLX4 does so in part by acting as a scaffold that controls and coordinates the XPF ERCC1, MUS81-EME1, and SLX1 structure-specific endonucleases in different DNA repair and recombination mechanisms. It also interacts with other important DNA repair and cell cycle control factors including MSH2, PLK1, TRF2, and TOPBP1 as well as with ubiquitin and SUMO. This review aims at providing an up-to-date and comprehensive view on the key functions that SLX4 fulfills to maintain genome stability as well as to highlight and discuss areas of uncertainty and emerging concepts. PMID- 30284475 TI - Three-dimensional nanofiberous PLLA/PCL scaffold improved biochemical and molecular markers hiPS cell-derived insulin-producing islet-like cells. AB - Nanofibrous scaffolds are considered as a new strategy for Type 1 diabetes mellitus therapy. We used a hybrid of poly-l-lactic acid (PLLA) and polycaprolactone (PCL) as three-dimensional (3D) culture models for differentiation of human induced pluripotent stem cells (hiPSCs) to beta islet like cluster cell compared with routine culture (2D). Morphological changes of cells were checked by microscope. mRNA endodermal SOX-17 on day 7 and pancreatic gene markers Pdx1, glucagon and Glut2 were evaluated on day 23 by qPCR. As well as, insulin and C-peptide protein expression was evaluated by immunocytochemistry staining. In addition, insulin and C-peptide secretion in various glucose concentrations was evaluated by ELISA. Light and scanning electron microscopy (SEM) microscope showed changes in induced cells. In tandem, these modifications were more evident in 3 D culture. Pdx1, Glucagon and Glut2 markers in PLLA/PCL were significantly higher in 3 D culture. In addition, qualitative immunochemistry showed that insulin and C-peptide were expressed in 2 D and 3 D culture medium. Furthermore, evaluation of insulin and C-peptide clarified that secretion of these proteins in PLLA/PCL scaffold were statistically different in 2 D and 3 D strategies. These findings suggest that functional matured induction cells on PLLA/PCL scaffold can be used for islet beta cell therapy and regenerative medicine. PMID- 30284474 TI - Inhibition of p38 mitogen-activated protein kinase exerts a hypoglycemic effect by improving beta cell function via inhibition of beta cell apoptosis in db/db mice. AB - The p38 mitogen-activated protein kinase (MAPK) pathway is involved in endoplasmic reticulum stress (ERS) and inflammation, which may play an important role in the pathogenesis of type 2 diabetes (T2DM). This study aimed to investigate whether p38 MAPK contributes to the pathogenesis of T2DM. 6-week-old female db/db mice were randomly assigned to Dmo and Dmi groups, and C57 mice were assigned as controls. The Dmi group was gavaged with the p38 MAPK inhibitor SB203580 for 9 weeks, and the effects on beta cell dysfunction and apoptosis were investigated. db/db mice showed higher food intake, body mass, fasting glucose, and plasma insulin levels than C57 mice. After SB203580 administration, blood glucose was significantly lower. HOMA beta and HOMA IR were improved. Islet mRNA expression levels of the ERS markers were lower. P38 MAPK inhibition reduced blood glucose and improved beta cell function, at least in part by reducing beta cell apoptosis. PMID- 30284476 TI - Refractive predictability and visual outcomes of an extended range of vision intraocular lens in eyes with previous myopic laser in situ keratomileusis. AB - PURPOSE: To evaluate the refractive predictability obtained with an extended range of vision intraocular lens in eyes with previous myopic laser in situ keratomileusis, confirming which intraocular lens power formula provides the most accurate calculation. METHODS: The study enrolled 71 eyes with previous successful myopic laser in situ keratomileusis surgery of 43 patients undergoing cataract surgery with implantation of the extended range of vision intraocular lens TECNIS Symfony (Johnson and Johnson Vision). Intraocular lens power was calculated using all American Society of Cataract and Refractive Surgeons formulas, and their average value was selected for implantation. Refractive outcomes were evaluated at 3 months postoperatively. RESULTS: Postoperative spherical equivalent within +/-0.50 and +/-1.00 D was found in 61.6% and 86.3% of eyes, respectively. In eyes with pre-laser in situ keratomileusis data available, no significant correlation was found between pre-laser in situ keratomileusis spherical equivalent and post-cataract surgery spherical equivalent (r = 0.237, p = 0.114). A postoperative spherical equivalent within +/-0.50 D was found in 65.2% and 55.6% of eyes in the subgroups with and without pre-laser in situ keratomileusis data available, respectively (p = 0.480). Statistically significantly higher differences between the intraocular lens power implanted and the calculation provided by the Potvin-Hill (p = 0.028) and Barrett True K No History formulas (p = 0.022) were found in those eyes with postoperative spherical equivalent > 0.50 D. CONCLUSION: The extended range of vision intraocular lens evaluated can provide a predictable refractive correction in eyes with previous laser in situ keratomileusis surgery. The Potvin-Hill and Barrett True K No History are the most adequate formulas to perform intraocular lens power calculations in these cases. PMID- 30284477 TI - Assay of miRNA in cell samples using enhanced resonance light scattering technique based on self aggregation of magnetic nanoparticles. AB - AIMS: miRNAs are regarded as potential biomarkers correlated with the development and progression of many diseases. However, it is a challenge to construct a sensitive method to detect them without using time-consuming radioactive labeling or complex amplification strategies. METHODS: A facile resonance light scattering (RLS) system was developed for the detection of miRNA employing magnetic nanoparticles (MNPs) as RLS probes. MNPs were coated with streptavidin. DNA probes were modified on the surface of MNPs based on the specific interaction of streptavidin and biotin forming MNPs@DNA probes. MNPs@DNA probes dispersed in homogeneous media causing low RLS signal. RESULTS & CONCLUSION: miRNA hybridized with DNA probes resulting in the aggregation of MNPs and inducing the enhancement of RLS intensity. miRNAs were determined successfully with limit of detection at 0.9 picomole per liter (pM). The potential clinical application of the present biosensor was also demonstrated by measuring miRNAs in human normal and cancer cells, and human serum samples. PMID- 30284478 TI - Responsiveness of the PROMIS and FAAM Instruments in Foot and Ankle Orthopedic Population. AB - BACKGROUND: Investigating the responsiveness of an instrument is important in order to provide meaningful interpretation of clinical outcomes. This study examined the responsiveness of the Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF), the PROMIS Pain Interference (PI), and the Foot and Ankle Ability Measure (FAAM) Sports subscale in an orthopedic sample with foot and ankle ailments. METHODS: Patients presenting to an orthopedic foot and ankle clinic during the years 2014-2017 responded to the PROMIS and FAAM instruments prior to their clinical appointments. The responsiveness of the PROMIS PF v1.2, PROMIS PI v1.1, and FAAM Sports were assessed using paired samples t test, effect size (ES), and standardized response mean (SRM) at 4 different follow-up points. A total of 785 patients with an average age of 52 years (SD = 17) were included. RESULTS: The PROMIS PF had ESs of 0.95 to 1.22 across the 4 time points (3, >3, 6, and <6 months) and SRMs of 1.04 to 1.43. The PROMIS PI had ESs of 1.04 to 1.63 and SRMs of 1.17 to 1.23. For the FAAM Sports, the ESs were 1.25 to 1.31 and SRMs were 1.07 to 1.20. The ability to detect changes via paired samples t test provided mixed results. But in general, the patients with improvement had statistically significant improved scores, and the worsening patients had statistically significant worse scores. CONCLUSION: The PROMIS PF, PROMIS PI, and FAAM Sports were sensitive and responsive to changes in patient-reported health. LEVEL OF EVIDENCE: Level II, prospective comparative study.

PMID- 30284480 TI - Photojournalism-Based Intervention Reduces Caregiver Burden and Depression in Alzheimer's Disease Family Caregivers. AB - PURPOSE: Art interventions have demonstrated holistic benefits for persons living with dementia and their caregivers. In this article, we describe the results of a pilot photojournalism program for 10 unpaid caregivers of persons living with dementia, with respect to caregivers' experience in the program and their psychological well-being. DESIGN: Caregivers participated in four sessions led by a professional photojournalist who taught principles of photography. Between the sessions, caregivers took photographs that represented what caregiving meant to them using digital cameras provided in the program. During the sessions, instruction was interspersed with discussion of caregivers' photographs. METHOD: Caregiver burden and depressive symptoms were measured pre- and postprogram. Qualitative exploration included sessions' observations, viewing caregivers' photographs, and recording caregivers' accompanying comments. FINDINGS: For participants with pre- and postprogram data, caregiver burden decreased significantly ( p = .037). For caregivers with pre- and postprogram data, depressive symptoms decreased nonsignificantly ( p = .066). Clinically meaningful reductions in caregiver burden and depressive symptoms were attained. Qualitative findings highlighted caregivers' strong engagement with the project, the facilitator, and other participants, and reflection on multiple aspects of their experience. CONCLUSIONS: This intervention helped caregivers creatively communicate their experience and demonstrated efficacy in the improvement of caregivers' psychological well-being. PMID- 30284481 TI - Combining SERS analysis of serum with PSA levels for improving the detection of prostate cancer. AB - AIM: Previous studies regarding surface-enhanced Raman scattering (SERS) of serum have shown promising initial results in discriminating prostate cancer, a strategy which could complement standard tests such as the prostate-specific antigen (PSA). MATERIALS & METHODS: SERS spectra of serum samples were combined with serum PSA levels to improve the discrimination accuracy between prostate cancer and nonmalignant pathologies in a cohort of 54 patients using principal component analysis-linear discriminant analysis (PCA-LDA). RESULTS & DISCUSSION: Combining SERS spectra with serum PSA levels in a single PCA-LDA model could discriminate between the two groups with an overall accuracy of 94%, yielding better results than either method alone. CONCLUSION: These results highlight that combining SERS-based cancer screening with serum PSA levels represents a promising strategy for improving the accuracy of prostate cancer diagnosis. PMID- 30284482 TI - A Safety and Cost Analysis of Outpatient Versus Inpatient Hindfoot Fusion Surgery. AB - BACKGROUND: Hindfoot fusion procedures are increasingly being performed in the outpatient setting. However, the cost savings of these procedures compared with the risks and benefits has not been clearly investigated. The objective of this study was to compare patient characteristics, costs, and short-term complications between inpatient and outpatient procedures. METHODS: This was a retrospective review of all patients who underwent inpatient and outpatient hindfoot fusion procedures by a single surgeon, at 1 academic institution, from 2013 to 2017. Data collected included demographics, operative variables, comorbidities, complications, costs, and subsequent reencounters. RESULTS: Of 124 procedures, 34 were inpatient and 90 were outpatient. Between procedural settings, with the numbers available, there was no significant increase in complication rate or frequency of reencounters within 90 days. There were no significant differences in the number of patients with reencounters related to the index procedure within 90 days (P = .43). There were 30 reencounters within 90 days after outpatient surgery versus 4 after inpatient surgery (P = .05). The total number of emergency room visits in the outpatient group within 90 days was significantly higher compared with the inpatient group (P = .04). The average cost for outpatient procedures was US$4159 less than inpatient procedures (P < .0001). CONCLUSION: Outpatient hindfoot fusion may be a safe alternative to inpatient surgery, with significant overall cost savings and similar rate of short-term complications. On the basis of these findings, we believe that outpatient management is preferable for the majority of patients, but further investigation is warranted. LEVELS OF EVIDENCE: Level III. PMID- 30284483 TI - Collagen coated electrospun polyethersulfon nanofibers improved insulin producing cells differentiation potential of human induced pluripotent stem cells. AB - Given the current conditions of life, one of the problems that the world is facing and is rapidly expanding is diabetes. The existing treatment methods are not responsive to these patients. Today, due to the advent of tissue engineering, cell and stem cell therapies, there are many hopes for treating these patients. In the present study, Polyethersulfone (PES) nanofibers were fabricated by electrospinning and then coated by collagen (PES-collagen), since this protein is abundant at the pancreatic extracellular matrix. After scaffold characterization, pancreatic differentiation potential of human induced pluripotent stem cells (hiPSCs) was investigated when cultured on PES-collagen by RT-qPCR, Immunofluorescence staining and insulin and C-peptide release assays. Pancreatic genes and proteins in cultured iPSCs on PES-collagen were expressed significantly higher than those cultured on culture plate as 2 D control group. Although differentiated cells in both groups are functional and secrete C-peptide and insulin in response to glucose challenges according to the immunoassay result. Considered together, PES-collagen demonstrated that it can be effective during pancreatic differentiation of the stem cells and can also be considered as a promising candidate for use in pancreatic tissue engineering application. PMID- 30284484 TI - Nanoparticle-mediated delivery of Tanshinone IIA reduces adverse cardiac remodeling following myocardial infarctions in a mice model: role of NF-kappaB pathway. AB - Our previous works have shown that tanshinone IIA inhibited maladaptive extracellular matrix remodeling in cardiac fibroblasts implicating its potential role in treating of pathologic cardiac remodeling. However, the intrinsically poor solubility and bioavailability of tanshinone IIA hindered its clinical application. Here we develop monomethoxy-poly (ethylene glycol)-poly (lactic acid)-D-alpha-Tocopheryl polyethylene glycol 1000 succinate (mPEG-PLA-TPGS) nanoparticle incorporating tanshinone IIA (tanshinone IIA-NPs) and study its efficacy in post-infarction left ventricular (LV) remodeling. Male C57BL/6 mice underwent left coronary artery ligation followed by subsequent intravenously injected tanshinone IIA-NPs therapy for 5 consecutive days. Treatment with tanshinone IIA-NP improved cardiac function, limited infarct expansion, and prevented left ventricle dilation at 4 weeks post-MI. Furthermore, cardiomyocytes inflammation, apoptosis and myocardial fibrosis were significantly attenuated in tanshinone IIA-NP treated mice. These effects also correlated with inhibition of IkappaB protein phosphorylation and NF-kappaB activation, leading to suppression of proinflammatory cytokine expression. Together, these results demonstrate tanshinone IIA-NP attenuated adverse cardiac remodeling and dysfunction mediated through prevention of IkappaB phosphorylation and NF-kappaB activation. Tanshinone IIA-NP is a novel approach to treat myocardial IR injury in patients with MI. PMID- 30284485 TI - Pharmacophore-based discovery of 2-(phenylamino)aceto-hydrazides as potent eosinophil peroxidase (EPO) inhibitors. AB - There is an increasing interest in developing novel eosinophil peroxidase (EPO) inhibitors, in order to provide new treatment strategies against chronic inflammatory and neurodegenerative diseases caused by eosinophilic disorder. Within this study, a ligand-based pharmacophore model for EPO inhibitors was generated and used for in silico screening of large 3 D molecular structure databases, containing more than 4 million compounds. Hits obtained were clustered and a total of 277 compounds were selected for biological assessment. A class of 2-(phenyl)amino-aceto-hydrazides with different substitution pattern on the aromatic ring was found to contain the most potent EPO inhibitors, exhibiting IC50 values down to 10 nM. The generated pharmacophore model therefore, represents a valuable tool for the selection of compounds for biological testing.

AB - Based on the structural analysis of tricyclic scaffolds as butyrylcholinesterase (BuChE) inhibitors, a series of pyrazolo[1,5-c][1,3]benzoxazin-5(5H)-one derivatives were designed, synthesized and evaluated for their acetylcholinesterase (AChE) and BuChE inhibitory activity. Compounds with 5 carbonyl and 7- or/and 9-halogen substitutions showed potential BuChE inhibitory activity, among which compounds 6a, 6c and 6g showed the best BuChE inhibition (IC50 = 1.06, 1.63 and 1.63 uM, respectively). The structure-activity relationship showed that the 5-carbonyl and halogen substituents significantly influenced BuChE activity. Compounds 6a and 6g were found nontoxic, lipophilic and exhibited remarkable neuroprotective activity and mixed-type inhibition against BuChE (Ki = 7.46 and 3.09 uM, respectively). Docking studies revealed that compound 6a can be accommodated into BuChE via five hydrogen bonds, one Pi Sigma interaction and three Pi-Alkyl interactions.

AB - TP53-induced glycolysis and apoptosis regulator (TIGAR) is a p53 target protein that plays critical roles in glycolysis and redox balance. Accumulating evidence shows that TIGAR is highly expressed in cancer. TIGAR redirects glycolysis and promotes carcinoma growth by providing metabolic intermediates and reductive power derived from pentose phosphate pathway (PPP). The expression of TIGAR in cancer is positively associated with chemotherapy resistance, suggesting that TIGAR could be a novel therapeutic target. In this review, we briefly presented the function of TIGAR in metabolic homeostasis in normal and cancer cells. Finally, we discussed the future directions of TIGAR research in cancer.

AB - Infections caused by pathogens resistant to the available antimicrobial treatments represent nowadays a threat to global public health. Recently, it has been demonstrated that carbonic anhydrases (CAs) are essential for the growth of many pathogens and their inhibition leads to growth defects. Principal drawbacks in using CA inhibitors (CAIs) as antimicrobial agents are the side effects due to the lack of selectivity toward human CA isoforms. Herein we report a new class of CAIs, which preferentially interacts with microbial CA active sites over the human ones. The mechanism of action of these inhibitors was investigated against an important fungal pathogen, Cryptococcus neoformans, revealing that they are also able to inhibit CA in microbial cells growing in vitro. At our best knowledge, this is the first report on newly designed synthetic compounds selectively targeting beta-CAs and provides a proof of concept of microbial CAs suitability as an antimicrobial drug target. PMID- 30284490 TI - Membrane sweeping at term to promote spontaneous labour and reduce the likelihood of a formal induction of labour for postmaturity: a systematic review and meta analysis. AB - The aim of this study was to evaluate the efficacy and the safety of membrane sweeping in promoting spontaneous labour and reducing a formal induction of labour for postmaturity. Based on articles published between 2005 and 2016, 12 electronic databases were searched. Relative risk (RR) and its 95% confidence interval (CI) were used as pooled statistics. A total of seven studies consisting of 2252 participants were selected for the review and meta-analysis. The results revealed that membrane sweeping is advantageous in promoting spontaneous labour (RR = 1.205, 95% CI: 1.133-1.282, p = <.001), and reducing the formal induction of labour for postmaturity (RR = 0.523, 95% CI: 0.409-0.669, p = <.001). The studies reported several varying outcomes for both maternal and foetal morbidities; meta-analyses were performed where possible on each of these and found there to be no statistically significant differences in outcome between the intervention and control groups. Impact Statement What is already known on this subject? Research suggests that a pregnancy which exceeds 42 weeks of gestation is associated with an increased risk of perinatal morbidity and mortality (Gulmezoglu et al. 2012 ). Consequently, a formal induction of labour is usually offered to low-risk pregnant women between 41 and 42 weeks of pregnancy. However, all of the induction methods carry some degree of risk in terms of the associated morbidities and effectiveness (Cunningham 2005 ; Simpson and James 2008 ; Thomas et al. 2014 ), as well as having an impact on NHS resources (Department of Health 2015 ), and the birth experience of women (Gatward et al. 2010 ). For these reasons, it is currently recommended by The National Institute for Health and Care Excellence (NICE 2008 ) that women are offered a membrane sweep to promote spontaneous labour prior to arranging a formal induction of labour. What the results of this study add? The results from this meta-analysis add to the body of existing evidence around membrane sweeping. This study clearly demonstrates that membrane sweeping is effective in promoting a spontaneous labour and thereby reducing the need for a formal induction of labour. However, the results of this review suggest that this effect is significant from 38 weeks of gestation, and is not dependent upon the number or timing of membrane sweeps performed. What the implications are of these findings for clinical practice and/or further research? There is no evidence supporting any increase in maternal or foetal morbidity suggesting that membrane sweeping is a safe procedure to offer to all low risk pregnant women. We recommend therefore that there could be a reduction in the gestation at which membrane sweeping is offered from 40 weeks for primiparous women and 41 weeks for multiparous women to 38 weeks onwards for all low risk women without any increased risk of maternal or foetal morbidity. This may result in a decreased risk of requiring a formal induction of labour for postmaturity. PMID- 30284492 TI - Clinical Outcomes and Complications of Midfoot Charcot Reconstruction With Intramedullary Beaming. AB - BACKGROUND: The purpose of this study was to examine the clinical outcomes and complications of patients with midfoot Charcot managed with midfoot osteotomy, realignment arthrodesis, and stabilization using intramedullary beams. METHODS: Consecutive patients with midfoot Charcot treated at a tertiary-care foot and ankle center from January 2013 to July 2016 who underwent corrective osteotomy with internal beam fixation were identified; 25 patients were included in the final analysis. Patients with a minimum 1-year follow-up were evaluated with physical examination, weightbearing radiographs, and patient-reported outcome measures. The primary outcome measure was defined as restoration of a stable, plantigrade, ulcer-free foot. Median age was 58 years, median BMI was 32, and 80% were diabetic (75% insulin-dependent). RESULTS: An ulcer-free, stable, plantigrade foot was obtained in 84% of patients. The radiographic lateral and anteroposterior Meary angle medians improved 9 degrees and 15 degrees , respectively, from preoperative to final postoperative weightbearing measurements ( P < .001 and P = .02). Overall, 46% of midfoot osteotomies were united on final radiographs at a median 18-month radiographic follow-up. Deep infection developed in 6 (24%) patients. The presence of a preoperative ulcer was found to be predictive of postoperative infection (P = .04); all 6 deep infections occurred in patients with preoperative ulceration. Four (16%) patients progressed to amputation at a mean 15 postoperative months, all for deep infection. CONCLUSION: Midfoot Charcot reconstruction with intramedullary beaming allowed for restoration of an ulcer-free, plantigrade foot in most patients, but the complication rates were high, especially in patients with preoperative ulceration.

PMID- 30284491 TI - Comparison of Two Different Techniques for Isolated Left Subclavian Artery Revascularization During Thoracic Endovascular Aortic Repair in Zone 2. AB - PURPOSE: To analyze the results of isolated left subclavian artery (LSA) revascularization during thoracic endovascular aortic repair (TEVAR) using carotid-subclavian bypass (CSbp) or chimney grafts (CGs). METHODS: A retrospective multicenter, observational study identified 73 patients (mean age 68+/-13 years, range 22-87; 56 men) with acute or chronic thoracic aortic lesions who underwent TEVAR with isolated LSA revascularization using either CSbp (n=42) or CGs (n=31) from January 2010 and February 2017. Primary endpoints were TEVAR related mortality, postoperative stroke, freedom from type Ia endoleak, and LSA patency. RESULTS: Primary technical success was achieved in all cases. Early TEVAR-related mortality was 4.2% (CSbp 2% vs CG 6%, p=0.571). Two (3%) patients had major ischemic strokes (one in each group). Mean follow-up was 24+/-21 months (range 1-72; median 15). Estimated freedom from TEVAR-related mortality was 93%+/ 3% (95% CI 84.3% to 97.0%) at 12 and 36 months, with no significant difference between CSbp and CG (p=0.258). Aortic reintervention did not differ between the groups (CSbp 5% vs CG 6%, p=0.356); nor did freedom from type Ia endoleak (CSbp 98% vs CG 87%, p=0.134). Gutter-related endoleaks occurred in 4 (13%) CG patients, but none of the patients experienced sac enlargement or the need for reintervention and none died. Primary patency of the LSA was 100% for the entire group during the observation period. CONCLUSION: In our experience, LSA revascularization proved most satisfactory and equally effective with both the CSbp and CG techniques, without discernible differences at midterm follow-up. PMID- 30284494 TI - Would antioxidant-loaded nanoparticles present an effective treatment for ischemic stroke? AB - Ischemic stroke is a leading cause of death and disability worldwide and is in urgent need of new treatment options. The only approved treatment for stroke restores blood flow to the brain, but much of the tissue damage occurs during the subsequent reperfusion. Antioxidant therapies that directly address ischemia reperfusion injury have shown promise in preclinical results. In this review, we discuss that reformulating antioxidant therapies as nanomedicine can potentially overcome the barriers that have kept these therapies from succeeding in the clinic. We begin by reviewing the pathophysiology of ischemic stroke with a focus on the effects of reperfusion injury. Next, we review nanotherapeutic systems designed to treat the disease with a focus on those addressing reperfusion injury. Mechanisms of passive and active transport required to traverse a blood brain barrier are discussed. Finally, we conclude by outlining design parameters for potentially successful nanomedicines as front-line therapeutics for ischemic stroke. PMID- 30284495 TI - Graphene oxide-chloroquine nanoconjugate induce necroptotic death in A549 cancer cells through autophagy modulation. AB - AIM: Chloroquine (Chl) has shown its potential in cancer therapy and graphene oxide (GO) exhibited excellent tumor-targeting ability, biocompatibility and low toxicity. We have endeavored to conjugate Chl to GO sheets and investigated the nonproliferation action on A549 cell lines along with cell signaling pathways. MATERIALS & METHODS: Cellular toxicity, autophagic flux modulation and cell death mechanism induced by GO-Chl have been investigated on A549 cell lines. RESULTS & CONCLUSION: GO-Chl induces accumulation of autophagosomes (monodansylcadaverine staining, green fluorescence protein-tagged LC3 plasmid and transmission electron microscopy observations) in A549 cells through the blockade of autophagic flux that serves as scaffold for necrosome assembling and activates necroptotic cell death. GO-Chl nanoconjugate could be used as an effective cancer therapeutic agent, by targeting the autophagy necroptosis axis. PMID- 30284497 TI - CCL25 chemokine-guided stem cell attraction: an assessment of possible benefits and risks. AB - Due to its chemoattraction potential on mesenchymal stromal cells of the CCL25/CCR9 axis, local application of CCL25 to severely damaged tissues may be a promising approach for regenerative therapies. Analysis of the given data revealed that CCL25/CCR9 signaling has a crucial role in regulation of an adult immune homeostasis. CCR9 expression variations resulted in dysfunctional immune response in colitis, rheumatoid arthritis and endometriosis. Regarding oncology, different neoplastic tissues exploit CCL25-dependent CCR9 signaling for either local proliferation or migration processes. The CCR9 pathway likely can trigger crosstalk between the Akt and NOTCH pathway and thus participate in the regulation of the neoplastic behavior. In conclusion, the designated application tissue requires precise molecular analysis of possible CCR9 expression due to its proto-oncogenic characteristics. PMID- 30284496 TI - Kinetic analysis of push-up exercises: a systematic review with practical recommendations. AB - Push-ups represent one of the simplest and most popular strengthening exercise. The aim of this study was to systematically review and critically appraise the literature on the kinetics-related characteristics of different types of push ups, with the objective of optimising training prescription and exercise-related load. A systematic search was conducted in the electronic databases PubMed, Google Scholar and Science Direct up to April 2018. Studies that reported kinetic data (e.g. initial and peak-force supported by the upper-limbs, impact-force, peak-flexion-moment of the elbow-joint, rate of propulsive- and impact-, and vertebral-joint compressive-forces) related to push-ups and included trained, recreational and untrained participants, were considered. The risk of bias in the included studies was assessed using the Critical Appraisal Skills Programme scale. From 5290 articles retrieved in the initial search, only 26 studies were included in this review. Kinetic data for 46 push-up variants were assessed. A limitation of the current review is that the relationship between our findings and actual clinical or practical consequences is not statistically proven but can only be inferred from our critical descriptive approach. Overall, this review provides detailed data on specific characteristics and intensities of push-up variations, in order to optimise exercise prescription for training and rehabilitation purposes.

AB - INTRODUCTION: The purpose of this study was to describe cultural health beliefs, practices, and experiences with professional health care in the United States by migrants from the Dominican Republic because their practices are largely unknown to professional providers. METHOD: A qualitative descriptive design was used, guided by Leininger's culture care theory and four-phase analysis method with a convenience sample of 15 self-identified migrant Dominican adults in three interpreter-assisted focus groups, in a familiar apartment. RESULTS: The following four themes emerged: Stress affects health and well-being, family support and faith in God are essential, use of folk care and professional care to treat illness and maintain health, and access to care, cost, communication and expressions of caring practices affect perceptions about the quality of professional care. DISCUSSION: Results informed development of specific strategies to provide culturally responsive care and risk-reduction interventions that promote health and improve quality of care in the Dominican community. PMID- 30284500 TI - Life in the Balance: Are Women's Possible Selves Constrained by Men's Domestic Involvement? AB - Do young women's expectations about potential romantic partners' likelihood of adopting caregiving roles in the future contribute to whether they imagine themselves in nontraditional future roles? Meta-analyzed effect sizes of five experiments (total N = 645) supported this complementarity hypothesis. Women who were primed with family-focused (vs. career-focused) male exemplars (Preliminary Study) or information that men are rapidly (vs. slowly) assuming greater caregiving responsibilities (Studies 1-4) were more likely to envision becoming the primary economic provider and less likely to envision becoming the primary caregiver of their future families. A meta-analysis across studies revealed that gender role complementarity has a small-to-medium effect on both women's abstract expectations of becoming the primary economic provider ( d = .27) and the primary caregiver ( d = -.26). These patterns suggest that women's stereotypes about men's stagnant or changing gender roles might subtly constrain women's own expected work and family roles. PMID- 30284501 TI - Dyadic interventions to promote physical activity and reduce sedentary behaviour: systematic review and meta-analysis. AB - Several interventions have targeted dyads to promote physical activity (PA) or reduce sedentary behaviour (SB), but the evidence has not been synthesised. Sixty nine studies were identified from MEDLINE, PsycINFO, and Web of Science, and 59 were included in the main meta-analyses (providing 72 independent tests). Intervention details, type of dyadic goal, participant characteristics, and methodological quality were extracted and their impact on the overall effect size was examined. Sensitivity analyses tested effect robustness to (a) the effects of other statistically significant moderators; (b) outliers; (c) data included for participants who were not the main target of the intervention. Dyadic interventions had a small positive, highly heterogeneous, effect on PA g = .203, 95% CI [0.123-0.282], compared to comparison conditions including equivalent interventions targeting individuals. Shared target-oriented goals (where both dyad members hold the same PA goal for the main target of the intervention) and peer/friend dyads were associated with larger effect sizes across most analyses. Dyadic interventions produced a small homogeneous reduction in SB. Given dyadic interventions promote PA over-and-above equivalent interventions targeting individuals, these interventions should be more widespread. However, moderating factors such as the types of PA goal and dyad need to be considered to maximise effects. PMID- 30284502 TI - Mesoporous silica-coated bismuth nanohybrids as a new platform for photoacoustic/computed tomography imaging and synergistic chemophotothermal therapy. AB - AIM: Polyethylene glycol modified mesoporous silica-coated bismuth nanohybrids (Bi@mSiO2-PEG) are fabricated for chemothermotherapy and multimodal imaging. MATERIALS & METHODS: The Bi@mSiO2-PEG are synthesized by coating mesoporous SiO2 onto metallic Bi cores, followed by PEG modification. Their cytotoxicity, photothermal effect, drug loading, antitumor effect and imaging abilities are evaluated. RESULTS: The nanohybrids show good biocompatibility, strong near infrared absorbance, high photothermal conversion efficiency (~36.6%), prominent infrared thermal imaging and photothermal killing efficacy on cancer cells. Utilizing the nanohybrids as potent drug carriers, a synergistic antitumor effect through chemothermotherapy is realized. Thanks to the superhigh x-ray attenuation coefficient and strong photothermal ability, high-contrast photoacoustic and x ray computed tomography imaging are achieved. CONCLUSION: These results reveal great potentials of the Bi@mSiO2-PEG for precise and efficient anticancer treatments. PMID- 30284503 TI - The intergroup empathy bias among incoming medical students. AB - BACKGROUND: Previous studies revealed a significant empathy decline over time among medical students. Scientific literature also supports the influence of group belonging on the empathy expression. OBJECTIVE: Through this study, we aimed to demonstrate whether group belonging (peers or patients) significantly influences empathy levels before students undertake their education in medicine. DESIGN: A total of 194 incoming medical students participated in our study. All participants filled-in the Interpersonal Reactivity Index under three primed situations (a general; a peers' one; a patients' one) at three different points in time during a session of information. RESULTS: Analyses revealed significant main effects of: gender; situations; and empathy dimensions. We also obtained a significant interaction effect between dimensions and situations. CONCLUSIONS: We showed that empathy levels were modulated by group belonging (25% of the variance was explained by group belonging). Post hoc analyses showed that the differences between the peers' and patients' situations tend to reveal an appropriate professional attitude with regard to patients because they displayed: (1) lower scores on personal distress and fantasy; (2) higher scores on perspective taking (as for peers); (3) stable scores on empathic concern in peers' and patients' situations. However, integrating empathy lessons in the educational program of medical students remains a priority. In a long-term perspective, these findings suggest an investigation of the impacts of group belonging on the evolution of students' empathy scores through their medicine studies. PMID- 30284504 TI - Structural insight into antisense gapmer-RNA oligomer duplexes through molecular dynamics simulations. AB - There is an extensive research carrying out on antisense technology and the molecules entering into clinical trials are increasing rapidly. Phosphorothioate (PS) is a chemical modification in which nonbridged oxygen is replaced with a sulfur, consequently providing resistance against nuclease activity. The 2'-4' conformationally restricted nucleoside has the structural features of both 2'-O methoxy ethyl RNA (MOE), which shows good toxicity profile, and locked nucleic acid (LNA), which shows good binding affinity towards the target RNA. These modifications have been studied and suggested that they can be a potential therapeutic agents in antisense therapy. Mipomersen (ISIS 301012), which contains the novel nucleoside modification has been used to target to apolipoprotein (Apo B), which reduces LDL cholesterol by 6-41%. In this study, classical molecular dynamics (MD) simulations were performed on six different antisense gapmer/target RNA oligomer duplexes (LNA-PS-LNA/RNA, RcMOE-PS-RcMOE/RNA, ScMOE-PS-ScMOE/RNA, MOE-PS-MOE/RNA, PS-DNA/RNA and DNA/RNA) to investigate the structural dynamics, stability and solvation properties. The LNA, MOE nucleotides present in respective duplexes are showing the structure of A-form and the PS-DNA nucleotides resemble the structure of B-form helix with respect to some of the helical parameters. Free energy calculations suggest that the oligomer, which contains LNA binds to the RNA strongly than other modifications as shown in experimental results. The MOE modified nucleotide, which although had a lower binding affinity but higher solvent accessible surface area (SASA) compared to the other modifications, may be influencing the toxicity and hence may be used it in Mipomersen, the second antisense molecule which is approved by FDA.

PMID- 30284505 TI - Effects of sample handling on the detection of porcine reproductive and respiratory syndrome virus in oral fluids by reverse-transcription real-time PCR. AB - We evaluated effects of handling procedures on detection of porcine reproductive and respiratory syndrome virus (PRRSV) in oral fluids (OFs) by reverse transcription real-time PCR (RT-rtPCR). The experiments were conducted using a composite sample of PRRSV-positive OF collected from 5-wk-old pigs vaccinated 15 d earlier with a modified-live PRRSV vaccine. Five pre-extraction sample-handling steps and all combinations thereof were evaluated: 1) thaw temperature (4 degrees C or 25 degrees C); 2) sample diluent (1:1 dilution with nuclease-free water or guanidinium thiocyanate-phenol); 3a) sonication of the sample (yes or no); 3b) temperature (4 degrees C or 25 degrees C) at which step 3a was conducted; and 4) temperature at which the sample was maintained after step 3b and until RNA extraction was initiated (4 degrees C or 25 degrees C). All combinations of the 5 sample-handling steps (i.e., 32 unique treatments) were tested in a completely randomized factorial design with 4 replicates and 1 negative control for each treatment. The entire experiment was repeated on 5 separate days to produce a total of 800 PRRSV RT-rtPCR results. Binary (positive or negative) data were analyzed by logistic regression and results (Ct) were analyzed using a generalized linear model. Overall, 1 false-positive result was observed among 160 negative controls (99.4% specificity), and 85 false-negative results were observed among the 640 known-positive samples (86.7% sensitivity). The most significant factor affecting test outcome was thaw temperature (4 degrees C or 25 degrees C); samples thawed at 4 degrees C had higher positivity rate (94% vs. 80%, p < 0.0001) and lower Ct (36.2 vs. 37.5, p < 0.0001). PMID- 30284506 TI - Intervention-Induced Motor Cortex Plasticity in Hemiparetic Children With Perinatal Stroke. AB - BACKGROUND: Clinical trials are suggesting efficacy of intensive therapy combined with brain stimulation to improve hand function in hemiparetic children with perinatal stroke. However, individual variability exists and the underlying neuroplasticity mechanisms are unknown. Exploring primary motor cortex (M1) neurophysiology, and how it changes with such interventions, may provide valuable biomarkers for advancing personalized neurorehabilitation. METHODS: Forty-five children (age 6-19 years) with hemiparesis participated in PLASTIC CHAMPS, a blinded, sham-controlled, factorial clinical trial. All received 80 hours of goal directed intensive upper extremity therapy. They were randomized into 4 groups: repetitive transcranial magnetic stimulation (rTMS) of contralesional M1, constraint therapy, both, or neither. Stimulus recruitment curves (SRC), short interval intracortical inhibition (SICI), and intracortical facilitation (ICF) for lesioned and contralesional M1 were investigated using TMS. Clinical assessments including the Assisting Hand Assessment (AHA) and Canadian Occupational Performance Measure (COPM) were conducted pre- and postintervention. RESULTS: All children completed the intervention and both function (AHA) and goal performance (COPM) improved with additive effects of rTMS and constraint ( P < .01). After intervention, motor-evoked potential (MEP) amplitudes from the contralesional M1 to the less-affected hand increased (n = 16, P < .02). SRC from the contralesional M1 to the less-affected hand increased (n = 25, P < .01). SICI of the contralesional M1 to the less-affected hand decreased (n = 30, P < .04). No changes were observed for ICF in either hemisphere ( P > .12). CONCLUSION: TMS applied before/after intensive neuromodulation therapies can explore M1 neurophysiology and plasticity in children with cerebral palsy. Increased MEP sizes and decreased SICI may reflect mechanisms of interventional plasticity and be potential biomarkers of individualized medicine. PMID- 30284507 TI - EXPRESS: Gremlin1 blocks vascular endothelial growth factor signalling in the pulmonary microvascular endothelium. PMID- 30284508 TI - Are anticoagulants still indicated in pulmonary arterial hypertension? AB - Pulmonary arterial hypertension (PAH) is a type of pulmonary hypertension that is a progressive, fatal disease. Multiple underlying mechanisms for PAH have been identified, including vasoconstriction, intimal proliferation, medial hypertrophy, inflammation, mitochondrial dysfunction, and in situ thrombosis. Because it is an uncommon disease, it has been challenging to identify a specific treatment that targets the dominant disease mechanism in a given patient. Early success demonstrating that some patients (approximately 10%) possess pulmonary vasoreactivity at diagnosis has driven the development of pulmonary vasodilators as the mainstay of treatment. However, while they improve exercise tolerance in clinical trials, their effect on survival is limited. Therapies that target underlying disease mechanisms that affect a majority of patients are clearly needed if we are to significantly improve overall survival. In the actual guidelines, chronic anticoagulation is no longer recommended in patients with idiopathic, hereditary, and drug-induced PAH although there is much indirect evidence for this. There are data from over 40 years which include: (1) pathology studies showing the presence of thrombotic lesions in a majority of patients with PAH, both idiopathic and associated with many other conditions; (2) a similar frequency of thrombotic lesions in patients treated with pulmonary vasodilators as was seen in the years before their use; (3) mechanistic studies showing that procoagulant conditions predispose to the development of intraluminal thrombosis that contributes to vascular remodeling and the progressive nature of the pathologic changes; and (4) observational studies that, with one exception, have demonstrated a substantial survival advantage in patients with PAH treated with oral anticoagulation. Acknowledging that no prospective randomized trial with anticoagulants has ever been done, we recommend a pragmatic approach to the use of anticoagulants in PAH. We suggest that the risks and benefits of chronic anticoagulation be considered in individual patients, and that warfarin be prescribed in patients with PAH, unless they have an increased risk of bleeding. The question of whether direct oral anticoagulants (DOACs) would provide the same benefit as vitamin K antagonists is valid, but presently there are no data at all regarding their use in PAH. However, in patients with PAH in whom warfarin anticoagulation management proves problematic, it is reasonable to switch the patient to a DOAC as is current practice for other conditions. PMID- 30284510 TI - Nonionic but water soluble, [Glycine-Pd-Alanine] and [Glycine-Pd-Valine] complexes. Their synthesis, characterization, antitumor activities and rich DNA/HSA interaction studies. AB - Two novel, neutral and water soluble Pd(II) complexes of formula [Pd(Gly)(Ala)] (1) and [Pd(Gly)(Val)] (2) (Gly, Ala, and Val are anionic forms of glycine, alanine, and valine amino acids, respectively) have been synthesized and characterized by FT-IR, UV-Vis, 1H-NMR, elemental analysis, and molar conductivity measurement. The data revealed that each amino acid binds to Pd(II) through the nitrogen of -NH2 and the oxygen of -COO- groups and acts as a bidentate chelate. These complexes have been assayed against leukemia cells (K562) using MTT method. The results indicated that both of the complexes display more cytotoxicity than the well-known anticancer drug, cisplatin. The interaction of the compounds with calf thymus DNA (CT-DNA) and human serum albumin (HSA) were assayed by a series of experimental techniques including electronic absorption, fluorescence, viscometry, gel electrophoresis, and FT-IR. The results indicated that the two complexes have interesting binding propensities toward CT-DNA as well as HSA and the binding affinity of (1) is more than (2). The fluorescence data indicated that both complexes strongly quench the fluorescence of ethidium bromide-DNA system as well as the intrinsic fluorescence of HSA via static quenching procedures. The thermodynamic parameters (DeltaH degrees , DeltaS degrees , and DeltaG degrees ) calculated from the fluorescence studies showed that hydrogen bonds and van der Waals interactions play a major role in the binding of the complexes to DNA and HSA. We suggest that both of the Pd(II) complexes exhibit the groove binding mode with CT-DNA and interact with the main binding pocket of HSA. Communicated by Ramaswamy H. Sarma.

AB - This study aimed to investigate the current situation and challenges on the development of medical massive open online courses (MOOCs) in China. A survey was constructed and the statistical analysis was adopted to evaluate the medical MOOCs. The results showed that the medical MOOC-related journal papers, conference papers, books and dissertations have risen dramatically over the past five years. In addition, the top 6 most representative MOOC platforms provide the majority (87%) of medical courses. The statistical analysis showed that PMPH-MOOC was the most influential medical MOOC platform in China. Compared to the foreign medical MOOCs, medical MOOCs in China were urgently in need of systemic planning, interaction activities and international certification. Overall, the findings suggest that the development of medical MOOCs for higher education has been achieved a great success along with a huge challenge.

AB - Paradoxical reactions (PRs) are exaggerated inflammatory responses owing to recovery of cellular immunity following initiation of anti-tuberculous therapy (ATT). The presentation is worsening of pre-existing symptoms or development of new lesions. A 14-year-old girl with multi-drug-resistant tuberculosis developed a recurrent asymptomatic retropharyngeal abscess while on ATT. She required multiple aspirations of the abscess. Xpert MTB/RIF detected Mycobacterium tuberculosis from the aspirate which was resistant to rifampicin; culture was negative. Following aspirations of the abscess, continued ATT and a 2-month course of corticosteroids, she remains well and has gained weight. A retropharyngeal abscess presenting in the form of a PR has not been reported previously in adults or children.

AB - Existing evidence suggest that cybersickness may be clinically different from "classic", motion-induced motion sickness; this evidence was however obtained in separate studies that focussed on just one of the two conditions. Our aim was to bring clarity to this issue, by directly comparing subjective symptoms and physiological effects of motion sickness induced by physical motion (Coriolis cross-coupling) and by immersion in virtual reality (ride on a roller coaster) in the same subjects. A cohort of 30 young healthy volunteers was exposed to both stimulations in a counter-balance order on two separate days at least one week apart. Nausea scores were recorded during the exposure, and Motion Sickness Assessment Questionnaire (MSAQ) was used to profile subjective symptoms post experiment. Tonic and phasic forehead skin conductance level (SCL) was measured before and during exposure in both stimulation methods. We found that nausea onset times and maximum nausea ratings were significantly correlated during both provocations (r=0.40, p=0.03 and r=0.56, p=0.0012, respectively). Symptom profiling with the MSAQ revealed substantial and significant correlations between total symptom scores (r=0.69, p<0.0001), between each of four symptom clusters and between 15/18 individual symptoms assessed in both conditions. Both provocations caused increase in tonic SCL associated with nausea, with a close correlation between the conditions (r=0.48, p=0.04). This was accompanied by a significant increase in the amplitude of phasic skin conductance transients in both experiments. We conclude that symptoms and physiological changes occurring during cybersickness and "classical" motion sickness are quite similar, at least during advanced stages of these malaises. PMID- 30284517 TI - Modelling mucosal surface roughness in the human velopharynx: a computational fluid dynamics study of healthy and obstructive sleep apnea airways. AB - : We previously published a unique methodology for quantifying human velopharyngeal mucosal surface topography and found increased mucosal surface roughness in obstructive sleep apnea (OSA) patients. In fluid mechanics, surface roughness is associated with increased frictional pressure losses and resistance. This study used computational fluid dynamics (CFD) to analyse the mechanistic effect of different levels of mucosal surface roughness on velopharyngeal airflow. METHODS: Reconstructed velopharyngeal models from OSA and Control subjects were modified, giving each model three levels of roughness, quantified by the curvature based surface roughness index (CBSRI0.6; range 24.8-68.6mm-1). CFD using the k-omega shear stress transport (SST) turbulence model was performed (unidirectional, inspiratory, steady state, 15l/min volumetric flow rate), and the effects of roughness on flow velocity, intraluminal pressure, wall shear stress and velopharyngeal resistance (Rv) were examined. RESULTS: Across all models, increasing roughness increased maximum flow velocity, wall shear stress and flow disruption, while decreasing intraluminal pressures. Linear mixed effects modelling demonstrated a log-linear relationship between CBSRI0.6 and Rv, with a common slope (log(Rv)/CBSRI0.6) of 0.0079 (95%CI 0.0015-0.0143; p=0.019) for all subjects, equating to a 1.9-fold increase in Rv when roughness increased from Control to OSA levels. At any fixed CBSRI0.6, the estimated difference in log(Rv) between OSA and Control models was 0.9382 (95%CI 0.0032-1.8732; p=0.049), equating to an 8.7-fold increase in Rv. CONCLUSION: This study supports the hypothesis that increasing mucosal surface roughness increases velopharyngeal airway resistance, particularly for anatomically narrower OSA airways, and may thus contribute to increased vulnerability to upper airway collapse in OSA patients.

AB - Isoflurane (ISO) is a commonly used anesthetic that offers rapid recovery for laboratory animal research. Initial studies indicated no difference in PaCO2 or pH between conscious (NO ISO) and 1% ISO exposed CD-1 mice. Our laboratory investigated if arterial blood sampling with 1% ISO is a suitable alternative to NO ISO sampling for monitoring ventilation in a commonly studied mouse strain. We hypothesized similar blood chemistry, breathing patterns and cardiovascular responses with NO ISO and 1% ISO. C57BL/6J mice underwent unrestrained barometric plethysmography to quantify the pattern of breathing. Mice exposed to hypoxic and hypercapnic gas under 1% ISO displayed blunted responses; with air there were no breathing differences. Blood pressure and heart rate were not different between NO ISO and 1% ISO exposed mice breathing air. Oxygen saturation was not different between groups receiving 2% ISO, 1% ISO, or air. Breathing frequency stabilized at ~11 minutes of 1% ISO following 2% ISO exposure, suggesting that 11 minutes is the optimal time for a sample in C57BL/6J mice. Blood samples at 1% ISO and NO ISO revealed no differences in blood pH and PaCO2 in C57BL/6J mice. Overall, this method reveals similar arterial blood sampling values in awake and 1% ISO CD-1 and C57BL/6J mice exposed to air. While this protocol may be appropriate in other mouse strains when a conscious sample is not feasible, caution is warranted to first identify breathing frequency responses at 1% ISO to tailor the protocol. PMID- 30284519 TI - A nutrient cocktail prevents lipid metabolism alterations induced by 20 days of daily steps reduction and fructose overfeeding: Result from a randomized study. AB - CONTEXT: Physical inactivity and sedentary behaviours are independent risks factors for numerous diseases. OBJECTIVE: We examined the capacity of a nutrient cocktail composed of polyphenols, omega-3 fatty acids, vitamin E and selenium to prevent the expected metabolic alterations induced physical activity and sedentary behaviors. DESIGN/SETTING/PARTICIPANTS: Twenty healthy trained men (averaging~14,000 steps/d and engaged in sports) were randomly divided into a control group (no supplementation) and a cocktail group for a 20-day free-living intervention during which they stopped exercise and decreased their daily steps to averaging~3000. During the last 10 days metabolic changes were further triggered by fructose overfeeding. On days 0, 10 and 20 body composition (DXA), blood chemistry, glucose tolerance (OGTT) and substrate oxidation (indirect calorimetry) were measured. Glucose tolerance included 1% fructose labelled with (U-13C) fructose to assess liver de novo lipogenesis. Histological changes and related cellular markers were assessed from muscle biopsies collected on days 0 and 20. RESULTS: While the cocktail did not prevent the decrease in insulin sensitivity and its muscular correlates induced by the intervention, it fully prevented the hypertriglyceridemia, the drop in fasting HDL and total fat oxidation, and the increase in de novo lipogenesis. The cocktail further prevented the decrease in type-IIa muscle fiber cross-sectional area and was associated with lower protein ubiquitination content. The circulating anti oxidant capacity was improved by the cocktail following the OGTT. CONCLUSION: A cocktail of nutrient compounds from dietary origin protects against the alterations in lipid metabolism induced by physical inactivity and fructose overfeeding. PMID- 30284520 TI - Transgenic overexpression of active HDAC4 in the heart attenuates cardiac function and exacerbates remodeling in infarcted myocardium. AB - Histone deacetylases (HDACs) play a critical role in modulating cardiac function and ischemic injury. HDAC4 was found to be elevated and activated in response to injury. However, whether HDAC4 mediates cardiac function is currently unknown. In this study, we created myocyte-specific activated HDAC4 transgenic mice to examine the role of HDAC4 in mediating cardiac function during development and response to infarction. There are no differences in cardiac function and gross phenotype between wild type and cardiomyocyte-specific HDAC4 transgenic mice at one month of age. However, cardiac dysfunction and vascular growth deficiency were displayed in six-month old HDAC4 transgenic mice as compared to wild type mice. Activation of HDAC4 increased heart and myocyte size, hypertrophic proteins, and interstitial fibrosis in six-month old mice, but not in one-month old mice. To further define whether activated HDAC4 in the heart could impact myocardial function and remodeling, myocardial infarction was created in both wild type and cardiomyocyte-specific HDAC4 transgenic mice. In myocardial infarction, the overexpression of activated HDAC4 exacerbated cardiac dysfunction and augmented cardiac remodeling and interstitial fibrosis, which was associated with the reduction of cardiokines in the heart. These results indicate the activation of HDAC4 as a crucial regulator for cardiac function in development and myocardial infarction. PMID- 30284521 TI - Disparities in rural-vs-urban achievement of millennium development goals in Cambodia: implications for current and future child health. AB - BACKGROUND: Cambodia has made significant economic, political, and health advancements with the implementation of the millennium development goals (MDG). Important gaps in child health still exist, however, and accurate assessments of lingering disparities within the country will be essential for meeting the Sustainable Development Goals by 2030. AIM: This investigation hypothesised that child-health improvements in rural areas of Cambodia continue to lag behind urban areas. The study objective was to identify specific disparities in rural achievement of MDG within Cambodia to direct future work in child health. METHODS: Surveys were conducted in 230 rural households in four villages in Kampot and Kampong Speu provinces to assess risk factors contributing to lack of village-level achievement of MDG. National urban and rural data were used for comparison. RESULTS: An under-5 death in the preceding year was reported by 11.5% (n = 26) of the households surveyed. Under-use of common public health interventions (vaccinations, clean drinking water, oral rehydration therapy, iodised salt, bed nets, antenatal care, and improved sanitation facilities) was observed in all villages. Under-use of the interventions was more common in rural than urban areas. CONCLUSION: Achievement of child-health-related MDG lags in rural areas of Cambodia. Child health risk factors varied widely among villages. Village-specific risk factors for which immediate action can be taken are a priority, particularly vaccination in Angkcheay and Takoa and clean drinking water in Pos Pong. Elimination of disparities in rural child health will ultimately require significant resource allocation in rural areas, e.g. improved sanitation facilities, piped water supply and sustained public health initiatives.

PMID- 30284524 TI - Sink traps as the source of transmission of OXA-48-producing Serratia marcescens in an intensive care unit. AB - BACKGROUND: Carbapenemase-producing Enterobacteriaceae (CPE) outbreaks are mostly attributed to patient-to-patient transmission via healthcare workers. OBJECTIVE: We describe successful containment of a prolonged OXA-48-producing S. marcescens outbreak after recognizing the sink traps as the source of transmission. METHODS: The Sheba Medical Center intensive care unit (ICU), contains 16 single-bed, semi closed rooms. Active CPE surveillance includes twice-weekly rectal screening of all patients. A case was defined as a patient detected with OXA-48 CPE >72 hours after admission. A root-cause analysis was used to investigate the outbreak. All samples were inoculated on chrom-agar CRE, and carbapenemase genes were detected using commercial molecular Xpert-Carba-R. Environmental and patient S. marcescens isolates were characterized using PFGE. RESULTS: From January 2016 to May 2017, 32 OXA-48 CPE cases were detected, and 81% of these were S. marcescens. A single clone was the cause of all but the first 2 cases. The common factor in all cases was the use of relatively large amounts of tap water. The outbreak clone was detected in 2 sink outlets and 16 sink traps. In addition to routine strict infection control measures, measures taken to contain the outbreak included (1) various sink decontamination efforts, which eliminated the bacteria from the sink drains only temporarily and (2) educational intervention that engaged the ICU team and lead to high adherence to 'sink-contamination prevention guidelines.' No additional cases were detected for 12 months. CONCLUSIONS: Despite persistence of the outbreak clones in the environmental reservoir for 1 year, the outbreak was rapidly and successfully contained. Addressing sink traps as hidden reservoirs played a major role in the intervention. PMID- 30284525 TI - Repeated Chlamydia trachomatis infections are associated with lower bacterial loads. AB - Chlamydia trachomatis (CT) infections remain highly prevalent. CT reinfection occurs frequently within months after treatment, likely contributing to sustaining the high CT infection prevalence. Sparse studies have suggested CT reinfection is associated with a lower organism load, but it is unclear whether CT load at the time of treatment influences CT reinfection risk. In this study, women presenting for treatment of a positive CT screening test were enrolled, treated and returned for 3- and 6-month follow-up visits. CT organism loads were quantified at each visit. We evaluated for an association of CT bacterial load at initial infection with reinfection risk and investigated factors influencing the CT load at baseline and follow-up in those with CT reinfection. We found no association of initial CT load with reinfection risk. We found a significant decrease in the median log10 CT load from baseline to follow-up in those with reinfection (5.6 CT/ml vs. 4.5 CT/ml; P = 0.015). Upon stratification of reinfected subjects based upon presence or absence of a history of CT infections prior to their infection at the baseline visit, we found a significant decline in the CT load from baseline to follow-up (5.7 CT/ml vs. 4.3 CT/ml; P = 0.021) exclusively in patients with a history of CT infections prior to our study. Our findings suggest repeated CT infections may lead to possible development of partial immunity against CT. PMID- 30284526 TI - Optimising amino acid absorption: essential to improve nitrogen balance and metabolic control in phenylketonuria. AB - It has been nearly 70 years since the discovery that strict adherence to a diet low in phenylalanine prevents severe neurological sequelae in patients with phenylalanine hydroxylase deficiency (phenylketonuria; PKU). Today, dietary treatment with restricted phenylalanine intake supplemented with non phenylalanine amino acids to support growth and maintain a healthy body composition remains the mainstay of therapy. However, a better understanding is needed of the factors that influence N balance in the context of amino acid supplementation. The aim of the present paper is to summarise considerations for improving N balance in patients with PKU, with a focus on gaining greater understanding of amino acid absorption, disposition and utilisation. In addition, the impact of phenylalanine-free amino acids on 24 h blood phenylalanine/tyrosine circadian rhythm is evaluated. We compare the effects of administering intact protein v. free amino acid on protein metabolism and discuss the possibility of improving outcomes by administering amino acid mixtures so that their absorption profile mimics that of intact protein. Protein substitutes with the ability to delay absorption of phenylalanine and tyrosine, mimicking physiological absorption kinetics, are expected to improve the rate of assimilation into protein and minimise fluctuations in quantitative plasma amino acid levels. They may also help maintain normal glycaemia and satiety sensation. This is likely to play an important role in improving the management of patients with PKU. PMID- 30284527 TI - Advancing the assessment of cultural orientation: A developmental and contextual framework of multiple psychological dimensions and social identities. AB - This paper aims to advance the scientific understanding of the role of culture, particularly cultural orientation, in development and psychopathology. We advance a theoretical framework that conceptualizes cultural orientation as a developmental construct represented by multiple psychological dimensions and social identities, and influenced by the contexts in which individuals are embedded. This perspective suggests that cultural orientation changes within individuals over time as a function of their experiences with and memberships in multiple groups, including the mainstream and ethnic culture groups, as well as a function of their normative developmental changes (i.e., the development of cognitive, social, and emotional capabilities). In addition, this framework places the development of an ethnic culture social identity (e.g., an ethnic identity) and a mainstream culture social identity in broader developmental perspectives that recognize these as two of the many social identities that are simultaneously embedded within the individual's self-concept and that simultaneously influence one's cultural orientation. To support the successful integration of culture into the study of development and psychopathology, we describe how highly reliable and valid measures of cultural orientation, indexed by individuals' social identities, are essential for generating a scientifically credible understanding of the role of cultural orientation in development and psychopathology. Further, we detail some best research practices associated with our developmental and contextual framework, and note some important considerations for researchers interested in studying cultural orientation, development, and psychopathology. PMID- 30284528 TI - Identifying the Underlying Mechanisms of Change During Acceptance and Commitment Therapy (ACT): A Systematic Review of Contemporary Mediation Studies. AB - BACKGROUND: Mediation studies test the mechanisms by which interventions produce clinical outcomes. Consistent positive mediation results have previously been evidenced (Hayes et al., 2006) for the putative processes that compromise the psychological flexibility model of acceptance and commitment therapy (ACT). AIMS: The present review aimed to update and extend the ACT mediation evidence base by reviewing mediation studies published since the review of Hayes et al. (2006). METHOD: ACT mediation studies published between 2006 and 2015 were systematically collated, synthesized and quality assessed. RESULTS: Twelve studies met inclusion criteria and findings were synthesized by (a) the putative processes under investigation, and (b) the outcomes on which processes were tested for mediation. Mediation results were found to be generally consistent with the psychological flexibility model of ACT. However, studies were limited in methodological quality and were overly focused on a small number of putative processes. CONCLUSIONS: Further research is required that addresses the identified methodological limitations and also examines currently under-researched putative processes. PMID- 30284529 TI - Interaction between environmental and familial affective risk impacts psychosis admixture in states of affective dysregulation. AB - BACKGROUND: Evidence suggests that cannabis use, childhood adversity, and urbanicity, in interaction with proxy measures of genetic risk, may facilitate onset of psychosis in the sense of early affective dysregulation becoming 'complicated' by, first, attenuated psychosis and, eventually, full-blown psychotic symptoms. METHODS: Data were derived from three waves of the second Netherlands Mental Health Survey and Incidence Study (NEMESIS-2). The impact of environmental risk factors (cannabis use, childhood adversity, and urbanicity) was analyzed across severity levels of psychopathology defined by the degree to which affective dysregulation was 'complicated' by low-grade psychotic experiences ('attenuated psychosis' - moderately severe) and, overt psychotic symptoms leading to help-seeking ('clinical psychosis' - most severe). Familial and non-familial strata were defined based on family history of (mostly) affective disorder and used as a proxy for genetic risk in models of family history * environmental risk interaction. RESULTS: In proxy gene-environment interaction analysis, childhood adversity and cannabis use, and to a lesser extent urbanicity, displayed greater-than-additive risk if there was also evidence of familial affective liability. In addition, the interaction contrast ratio grew progressively greater across severity levels of psychosis admixture (none, attenuated psychosis, clinical psychosis) complicating affective dysregulation. CONCLUSION: Known environmental risks interact with familial evidence of affective liability in driving the level of psychosis admixture in states of early affective dysregulation in the general population, constituting an affective pathway to psychosis. There is interest in decomposing family history of affective liability into the environmental and genetic components that underlie the interactions as shown here. PMID- 30284530 TI - Biology and life history of Lema praeusta (Fab.) (Coleoptera: Chrysomelidae), a biocontrol agent of two Commelinaceae weeds, Commelina benghalensis and Murdannia nudiflora. AB - We examined previous reports of Lema praeusta (Fab.) (Coleoptera: Chrysomelidae) as a minor pest of turmeric, eggplant, bottle gourd and pumpkin leaves, but no feeding damage by larvae and adults of L. praeusta were recorded by us on these leaves. We observed feeding by the larvae and adults of L. praeusta on ten species of Commelinaceae plants in no-choice tests. The biology, fecundity and life table parameters of L. praeusta on two Commelinaceae weeds, Commelina benghalensis L. and Murdannia nudiflora (L.) Brenan were determined under laboratory conditions (27 +/- 1 degrees C, 65 +/- 5% RH and 12L:12D). Total larval development times of L. praeusta were 6.36 +/- 0.07 and 7.28 +/- 0.11 days (mean +/- SE) on C. benghalensis and M. nudiflora, respectively. Adult females lived 106.25 +/- 1.17 and 77.65 +/- 0.91 days (mean +/- SE) on C. benghalensis and M. nudiflora, respectively. Each female laid 272.95 +/- 2.39 and 224 +/- 1.74 eggs (mean +/- SE) during a lifetime on C. benghalensis and M. nudiflora, respectively. The net reproductive rate (Ro), intrinsic rate of increase (rm), generation time (Tc), doubling time (DT) and finite rate of increase (lambda) were 136.48, 0.14, 36.17, 5.10 and 1.41 on C. benghalensis, respectively, whereas Ro, rm, Tc, DT and lambda were 112, 0.20, 23.64, 3.47 and 1.51 on M. nudiflora, respectively, suggesting that L. praeusta could be a potential biocontrol agent against C. benghalensis and M. nudiflora in the fields of rice, maize, sorghum, soybean, mung bean, peanut and cotton.

AB - Particulate matter (PM) air pollution has been established as a significant threat to public health and a destructive factor to the climate and eco-systems. In order to eliminate the effects of PM air pollution, various air filtering strategies based on electrospun nanofibers have recently been developed. However, to date, almost none of the existing nanofibers based air filters can meet the requirements of high-performance air PM filtering, including high PM removal efficiency, low resistance to airflow, and long service life, etc. For the first time, we report a fabrication process using the electrospinning method for air filters based on thermoplastic polyurethane (TPU) nanofibers. The average diameters of TPU nanofibers are tunable from 0.14 +/- 0.06 MUm to 0.82 +/- 0.22 MUm by changing the TPU concentrations in polymeric solutions. The optimized TPU nanofibers based air filters demonstrate the attractive attributes of high PM2.5 removal efficiency up to 98.92%, good optical transparency of ~60%, low pressure drop of ~10 Pa, high quality factor of 0.45 Pa-1, and long service life under the flow rate of 200 ml min-1, which is ground-breaking compared with the existing nanofibers based air filters. These TPU nanofibers based air filters, with the excellent filtration performance and light transmittance, will shed light on the future research of nanofibers for various filtration applications and greatly benefit the public health by reducing the effects of PM air pollution. PMID- 30284535 TI - A plant chitinase controls cortical infection thread progression and nitrogen fixing symbiosis. AB - Morphogens provide positional information and their concentration is key to the organized development of multicellular organisms. Nitrogen-fixing root nodules are unique organs induced by Nod factor-producing bacteria. Localized production of Nod factors establishes a developmental field within the root where plant cells are reprogrammed to form infection threads and primordia. We found that regulation of Nod factor levels by Lotus japonicus is required for the formation of nitrogen-fixing organs, determining the fate of this induced developmental program. Our analysis of plant and bacterial mutants shows that a host chitinase modulates Nod factor levels possibly in a structure-dependent manner. In Lotus, this is required for maintaining Nod factor signalling in parallel with the elongation of infection threads within the nodule cortex, while root hair infection and primordia formation are not influenced. Our study shows that infected nodules require balanced levels of Nod factors for completing their transition to functional, nitrogen-fixing organs. PMID- 30284537 TI - Engineering of microscale vascularized fat that responds to perfusion with lipoactive hormones. AB - Current methods to treat large soft-tissue defects mainly rely on autologous transfer of adipocutaneous flaps, a method that is often limited by donor site availability. Engineered vascularized adipose tissues can potentially be a viable and readily accessible substitute to autologous flaps. In this study, we engineered a small-scale adipose tissue with pre-patterned vasculature that enables immediate perfusion. Vessels formed after one day of perfusion and displayed barrier function after three days of perfusion. Under constant perfusion, adipose tissues remained viable and responded to lipoactive hormones insulin and epinephrine with lipid accumulation and loss, respectively. Adipocyte growth correlated inversely with distance away from the feeding vessel, as predicted by a Krogh-type model. PMID- 30284540 TI - Co-axial wet-spinning in 3D bioprinting: state of the art and future perspective of microfluidic integration. AB - Nowadays, 3D bioprinting technologies are rapidly emerging in the field of tissue engineering and regenerative medicine as effective tools enabling the fabrication of advanced tissue constructs that can recapitulate in vitro organ/tissue functions. Selecting the best strategy for bioink deposition is often challenging and time consuming process, as bioink properties-in the first instance, rheological and gelation-strongly influence the suitable paradigms for its deposition. In this short review, we critically discuss one of the available approaches used for bioprinting-namely co-axial wet-spinning extrusion. Such a deposition system, in fact, demonstrated to be promising in terms of printing resolution, shape fidelity and versatility when compared to other methods. An overview of the performances of co-axial technology in the deposition of cellularized hydrogel fibres is discussed, highlighting its main features. Furthermore, we show how this approach allows (i) to decouple the printing accuracy from bioink rheological behaviour-thus notably simplifying the development of new bioinks-and (ii) to build heterogeneous multi-materials and/or multicellular constructs that can better mimic the native tissues when combined with microfluidic systems. Finally, the ongoing challenges and the future perspectives for the ultimate fabrication of functional constructs for advanced research studies are highlighted.

AB - Electrocaloric effect (ECE) of ferroelectric materials is highly dependent on the domain transition with temperature. The effect of domain transition on the ECE of PbTiO3 (PTO) ferroelectric thin films subjected to different mismatch strains is investigated by a phase field model based on the time-dependent Ginzburg-Landau equation. The simulation results demonstrate that there exists a multiple-to single domain transition induced by temperature in the PTO thin film. The domain transition occurs at a temperature that is much lower than Curie temperature, resulting in a giant negative ECE in the strained ferroelectric thin film. Furthermore, the domain transition temperature and the corresponding negative ECE can be tuned by the magnitude of mismatch strain. The present study suggests an effective way to obtain a giant negative ECE by domain transitions in the strained ferroelectric thin film.

PMID- 30284543 TI - Proof of nicotine transfer to rat pups through maternal breast feeding to evaluate the neurobehavioral consequences of nicotine exposure. AB - This study investigates the transfer of nicotine from lactating dams to their offspring through breast milk, in the frame of a research focused to ascertain toxicological and neuro-behavioural effects on pups as consequence of either unavoidable ("yoked & forced") or voluntary ("freely-chosen") maternal nicotine exposure. To this aim, plasmatic concentrations of nicotine and cotinine were determined by LC-MS/MS in Wistar rat pups whose mothers were orally administered with nicotine during lactation. Mothers were divided into a voluntary drinking group, an unavoidable consumption group, and controls. The limits of detection and quantification of the LC-MS/MS method were 0.20 and 0.65 ng/mL, respectively. Within-laboratory reproducibility (CV%) was <12%, with recovery of 86.2-118.8%. Results showed the presence of nicotine in 67% of samples from freely-chosen consumption group (1.30 +/- 0.31 ng/mL) and in 60% of samples from yoked consumption group (1.19 +/- 0.62 ng/mL); cotinine was found in all the samples from freely-chosen (1.92 +/- 0.77 ng/mL) and yoked-consumption groups (1.43 +/- 0.30 ng/mL). Data provide an evidence-based support to maternal/offspring nicotine transfer as function of different ways of oral exposure. PMID- 30284544 TI - The effect of the burden of caregiving for people with spinal cord injury (SCI): a cross-sectional study. AB - AIM: To assess the caregiver burden (CB) of caregivers for people with Spinal Cord Injury (SCI) and to examine the psychological impact of the burden of caregiving. MATERIALS AND METHODS: Cross-sectional study. A set of structured questionnaires was administered to 55 family caregivers of individuals with SCI. The Modified Barthel Index was used to evaluate the independence of care recipients. The Caregiver Burden Inventory was modified and used to assess the CB. The Family Strain Questionnaire - Short Form was administered to measure the psychological impact of CB. The Short Form 36 was used to assess the health status of the participants. RESULTS: CB affects mainly the domains related to time management, the physical condition of caregivers and their sense of personal failure. An increased level of CB and the dependency level of SCI survivors is significantly correlated (p < 0.01) with an increase in the need of psychological support and a decrease in perceived health and quality of life. CONCLUSIONS: Caregiving for people with SCI implies the occurrence of CB. The contribution of caregivers should be recognised and supported with tailored relief interventions. PMID- 30284545 TI - Pain prevalence, severity, assessment and management in hospitalized adult patients: a result of a multicenter cross sectional study. AB - INTRODUCTION: The measurement of pain prevalence among the patients admitted to hospital, estimated that pain remains a common problem for patients. METHODS: This is a multi-center cross sectional study carried out in Italian Hospitals, where data was collected in only one day. All patients aged at least 18 years, hospitalized able or unable to communicate, were eligible to be included in the study. Patients with curarization or quadriplegia (any cause) were excluded. RESULTS: Some hospitals and residential structures took part in our research, 26 centers in total. Pain prevalence has been observed in 268 patients (38%) (95% CI = 34%-41%) (range within wards 31-47%). Women are at higher risk than men (RR = 1.59, 95% CI = 1.29-1.95). Pain prevalence was more observed at 10.9 (+ 1.46) days after surgery. Severe pain has been observed in 148 (21.2%) cases. Pain was managed in 223 (83.2%) cases, and it was predominantly treated with the administration of paracetamol (n = 55; 24.7%) within 30 minutes after having ascertained the presence of pain. CONCLUSIONS: Pain is reported by about 4 out of 10 adults, with a higher prevalence of cases in women, and its appearance does not depend on the care setting. In order to assess the prevalence of pain carefully, an Italian study that involves all regions and a large number of the centers may be necessary. PMID- 30284546 TI - Relationship between anatomical sites and severity of the lesions and use of alcohol and psychotropic substances in traumatized drivers admitted to the Emergency Department of Padua, Italy. AB - INTRODUCTION: Driving under the influence of alcohol and/or psychoactive substances increases the risk of road accidents, but it is controversial whether this affects site and severity of injuries. MATERIAL AND METHODS: We search for alcohol, cannabinoids, cocaine, benzodiazepines, opioids, methadone, amphetamines and barbiturates in biological fluids of 1764 traumatized drivers admitted to the Emergency Department (ED) of Padua between 2010 and 2014. RESULTS: We note correlation between alcohol and benzodiazepines and admission in ICU and between all the intoxications and the reserved prognosis. The sites of injuries were: head (37.13%), maxillofacial (8.33%), spinal column (44.67%), thoracic (15.31%), abdominal (5%), pelvic (2.55%) and limb traumas (23.58%). We observed a correlation between head trauma (p < 0.0001), maxillofacial trauma (p = 0.0418), thoracic trauma (p = 0.0215), pelvic trauma (p = 0.0008), spinal column trauma (p < 0.0001) and the totality of the intoxication and an association between benzodiazepines and thoracic and pelvic trauma. CONCLUSIONS: Alcohol and benzodiazepines intoxication increases the risk of reserved prognosis and admission in ICU; benzodiazepines intoxication correlates with thoracic and pelvic trauma.

AB - BACKGROUND: The use of medicines to treat common complaints, such as headache, stomachache, difficulty in getting to sleep and nervousness, is widespread among adolescents, and is increasing. The aim of this survey was to estimate the prevalence of recurrent specific complaints among 15-year-old adolescents in Tuscany over three years (2006, 2010 and 2014) and that of medicine use to treat these complaints among boys and girls. METHODS: The present study is based on data from the Tuscan HBSC studies at three time points (2006, 2010 and 2014), which involved 2830 adolescents, aged 15 years old (1395 boys and 1435 girls). RESULTS: Overall, the data confirm that adolescents who suffer from recurrent complaints are more likely to use medicines. The prevalence rates of all complaints were higher in girls than in boys in the three years considered. Over the whole period, headache, stomachache and difficulty in getting to sleep increased in girls, while boys displayed significant decrease in nervousness and stomachache. CONCLUSION: Our findings underline the fact that the use of medicines in adolescence is a public health concern and constitutes an emerging issue that needs greater attention and investigation on the part of scientific research. PMID- 30284548 TI - Assessment of health literacy skills in family doctors' patients by two brief, self-administered Italian measures. AB - Health Literacy (HL) is an important health determinant: low HL skills result in less healthy choices, riskier behavior, poorer health, less self-management and more hospitalization. An observational study was conducted in a selected population, attending the waiting rooms of family general practitioners, with the aim of assessing HL capabilities through the administration of two HL screeners (IMETER and SILS-IT), and comparing the two measures. An anonymous questionnaire was administered, consisting of the Italian versions of the two tests on a single sheet. Demographic data, as well as concomitant chronic diseases and vaccines received, were also collected. HL skills were measured by the scores observed at both tests, and by the frequency of subjects with low HL levels according to the respective cut-off values. Overall, 305 questionnaires were collected and analyzed. Regarding IMETER, the observed frequency of subjects with low HL skills was 25.2% and the mean score and mean adjusted-score (26.3 +/- 8.8 and 23.2 +/- 9.4, respectively) were lower than those observed in previous studies. Similarly, at SILS-IT the percentage of subjects with low skills (49.9%) was higher than observed previously. IMETER showed high internal consistency (Cronbach's alpha > 0.9). The two measures were significantly correlated, although with a low Spearman's coefficient, and IMETER did not provide significant information about the probability to predict low HL according to SILS-IT. These results are explainable by the differences in assessment and domains between the two tests, both reliable and suitable to screen patients with low functional HL.

PMID- 30284550 TI - Prevalence of frailty at population level in European ADVANTAGE Joint Action Member States: a systematic review and meta-analysis. AB - INTRODUCTION: Although frailty is common among community-dwelling older adults, its prevalence in Europe and how this varies between countries is unclear. METHODS: A systematic review and meta-analysis of literature on frailty prevalence in 22 European countries involved in the Joint Action ADVANTAGE was conducted. RESULTS: Sixty-two papers, representing 68 unique datasets were included. Meta-analysis showed an overall estimated frailty prevalence of 18% (95% confidence interval, CI, 15-21%). The prevalence in community (n = 53) vs non-community based studies (n = 15) was 12% (95% CI 10-15%) and 45% (95% CI 27 63%), respectively. Pooled prevalence in community studies adopting a physical phenotype was 12% (95% CI 10-14%, n = 45) vs 16% (95% CI 7-29%, n = 8) for all other definitions. Sub-analysis of a subgroup of studies assessed as high-quality (n = 47) gave a pooled estimate of 17% (95% CI 13-21%). CONCLUSIONS: The considerable and significant heterogeneity found warrants the development of common methodological approaches to provide accurate and comparable frailty prevalence estimates at population-level. PMID- 30284551 TI - Incidence of frailty: a systematic review of scientific literature from a public health perspective. AB - INTRODUCTION: Because of the dynamic nature of frailty, prospective epidemiological data are essential to calibrate an adequate public health response. METHODS: A systematic review of literature on frailty incidence was conducted within the European Joint Action ADVANTAGE. RESULTS: Of the 6 studies included, only 3 were specifically aimed at estimating frailty incidence, and only 2 provided disaggregated results by at least gender. The mean follow-up length (1-22.2 years; median 5.1), sample size (74-6306 individuals), and age of participants (>= 30-65) varied greatly across studies. The adoption of incidence proportions rather than rates further limited comparability of results. After removing one outlier, incidence ranged from 5% (follow-up 22.2 years; age >= 30) to 13% (follow-up 1 year, age >= 55). CONCLUSIONS: Well-designed prospective studies of frailty are necessary. To facilitate comparison across studies and over time, incidence should be estimated in person-time rate. Analyses of factors associated with the development of frailty are needed to identify high-risk groups. PMID- 30284552 TI - Transitions and trajectories in frailty states over time: a systematic review of the European Joint Action ADVANTAGE. AB - INTRODUCTION: Frailty is a dynamic syndrome and may be reversible. Despite this, little is known about trajectories or transitions between different stages of frailty. METHODS: A systematic review was conducted, selecting studies reporting frailty trajectories or transition states for adults in any settings in European ADVANTAGE Joint Action Member States. RESULTS: Only three papers were included. Data were from longitudinal community-based cohorts in the United Kingdom, Netherlands and Italy. The English study investigated the effect of physical activity on the progression of frailty over a 10-year period. Two presented data on the proportion of participants experiencing at least one frailty transition over time (32.6% in the Italian sample aged >= 65 years followed for 4.4 years; 34.3% in the Dutch sample aged 65-75 years, followed for 2 years). CONCLUSIONS: Data on frailty trajectories and transition states were limited and heterogeneous. Well-designed prospective studies and harmonized approaches to data collection are now needed. PMID- 30284553 TI - Population screening, monitoring and surveillance for frailty: three systematic reviews and a grey literature review. AB - INTRODUCTION: Little is known about programmes or interventions for the screening, monitoring and surveillance of frailty at population level. METHODS: Three systematic searches and an opportunistic grey literature review from the countries participating in the ADVANTAGE Joint Action were performed. RESULTS: Three studies reported local interventions to screen for frailty, two of them using a two-step screening and assessment method and one including monitoring activities. Another paper reviewed both providers' and participants' experiences of screening activities. Three on-going European projects and population screening programmes in primary care await evaluation. An electronic Frailty Index for use with patients' primary care records has been recently validated. No study described systematic processes for the surveillance of frailty. CONCLUSIONS: There is insufficient evidence for the effectiveness of population level screening, monitoring and surveillance of frailty. Development and evaluation of community-based two-step programmes including those that incorporate electronic health records, particularly in primary care, are now needed. PMID- 30284554 TI - Expression of Androgen Receptor Variant 7 (AR-V7) in Circulated Tumor Cells and Correlation with Drug Resistance of Prostate Cancer Cells. AB - BACKGROUND Prostate cancer is a common type of malignant tumor invading the male reproductive-urinary system, which has increasing incidence worldwide. Androgen receptor variant 7 (AR-V7) participates in regulating prostate cancer cell proliferation and gene expression. This study aimed to investigate the expression of AR-V7 in circulated tumor cells (CTCs) in patients with prostate cancer and to assess its correlation with drug sensitivity against enzalutamide or abiraterone. MATERIAL AND METHODS Blood samples of prostate cancer patients were collected for separating CTCs, in which mRNA expression level of full-length AR and AR-V7 was measured to analyze their correlation with enzalutamide or abiraterone resistance. Progression-free survival (PFS) of patients with different AR-V7 expression levels was compared. AR-V7 was overexpressed in transfected prostate cancer cells, and its effects on proliferation were analyzed by clonal formation assay. RESULTS qRT-PCR showed AR-V7 overexpression in a total of 13 patients; 76.92% of these patients developed drug resistance, the distal metastasis of which was significantly higher than that in the group with AR-V7 downregulation, with lower PFS (p<0.01). In cultured prostate cancer cells, AR-V7 upregulation resulted in a significantly higher clonal formation rate than in the control group with enzalutamide-containing medium (p<0.05). CONCLUSIONS In prostate cancer cells, AR-V7 expression is correlated with drug resistance, as AR-V7 upregulation leads to enhanced proliferation potency of cancer cells, indicating unfavorable prognosis of patients. PMID- 30284555 TI - Social support in groups of mothers with different family status and its significance for satisfaction with work. AB - BACKGROUND: The purpose of the study was to determine to what degree social support is differentiated by family situation, with consideration of single motherhood as a difficult circumstance, and to establish if social support is significant for satisfaction with work in the studied group of mothers. MATERIAL AND METHODS: The sample consisted of 421 mothers: 206 (49%) of them were in a formal or casual relationship, and the remaining 215 (51%) were single mothers. The sample was studied by means of the Berlin Social Support Scales (BSSS), and the Scale of Satisfaction with Work. RESULTS: The results showed that single mothers perceived and obtained significantly less social support than mothers in relationships, and they offered to their relatives much more protective support (p = 0.006). Satisfaction with work among mothers - regardless of the family status - grows if the mother receives more social support. The information support received by mothers in relationships is not significantly related to satisfaction with work; seeking that type of support by single mothers does not have a meaningful relationship with satisfaction with work, either. Moreover, regardless of the mothers' family status, satisfaction with work is significantly differentiated by each type of social support, except for protective support. CONCLUSIONS: Social support is differentiated by the mothers' situation in the family and at work, and it has a different impact on single mothers from the impact on mothers in relationships. Med Pr 2018;69(5):497 507. PMID- 30284556 TI - [Venous thromboembolism and atrial fibrillation in patients with cancer]. PMID- 30284557 TI - [Treatment of cancer-associated venous thromboembolism]. AB - Most clinical practice guidelines recommend low molecular weight heparin for the treatment of venous thromboembolism (VTE) in cancer patients. In the Hokusai VTE Cancer study, 1050 patients with cancer and acute VTE were randomized to oral edoxaban or subcutaneous dalteparin for at least 6 months and up to 12 months. Edoxaban was non-inferior to dalteparin with respect to the composite outcome of recurrent VTE and major bleeding. The rate of recurrent VTE was numerically lower, but the rate of major bleeding was significantly higher with edoxaban. The frequency of severe major bleeding was similar with edoxaban and dalteparin. The difference in major bleeding was mainly driven by a higher rate of upper gastrointestinal bleeding with edoxaban, especially in patients with gastrointestinal cancer. The pilot Select-D study randomized 406 patients with cancer and VTE to rivaroxaban or dalteparin for 6 months. Recurrent VTE was reduced, while both major and clinically relevant non major bleeding were significantly increased with rivaroxaban. Bleeding mostly involved the gastrointestinal tract and occurred in patients with gastroesophageal cancer. While waiting for ongoing studies on direct oral anticoagulants, the results of the Hokusai VTE Cancer suggest that edoxaban may represent a valuable alternative to low molecular weight heparin for the treatment of cancer-associated VTE. In patients with gastrointestinal cancer, the use of edoxaban requires careful benefit-risk weighting, taking into consideration patient's preferences. PMID- 30284558 TI - [Edoxaban in patients with atrial fibrillation and cancer]. AB - Advances in cancer therapy have led to a significant improvement of survival in most types of malignancies over the past few decades. As a result, there is a growing population of cancer survivors, expected to reach 18 million people in 2030 in the US and a similar number in Europe. Interestingly, cancer survivor studies have shown that although about half of these patients eventually die of cancer, one third of them actually die of cardiovascular disease. Arrhythmias represent a significant part of cardiovascular complications and atrial fibrillation is the main arrhythmia occurring in cancer patients.Antithrombotic therapy is a challenge: the optimal international normalized ratio (INR) level in patients on therapy with vitamin K antagonists is achieved in only 12% of them; in these patients, direct oral anticoagulants seem to be effective and safe for the prevention of stroke and systemic embolic events compared to warfarin and have similar risk of major bleeding. Among the trials, ENGAGE AF-TIMI 48 provides more data on the efficacy and safety of edoxaban in cancer patients.

PMID- 30284560 TI - Infrared spectroscopy based on broadly tunable quantum cascade lasers and polycrystalline diamond waveguides. AB - Recently emerging broadly tunable quantum cascade lasers (tQCL) emitting in the mid-infrared (MIR) are a versatile alternative to well established thermal emitters in combination with interferometers as applied in Fourier transform infrared (FTIR) spectroscopy. The wide and highly spectrally resolved wavelength tuning characteristics along with superior spectral energy density renders laser based vibrational spectroscopy methods an efficient alternative vs. conventional molecular spectroscopies. Using diamond in attenuated total reflection (ATR) sensing formats benefits from the physical robustness and chemical resistivity of the internal reflective element (IRE) material. While inherent material absorption frequently limits the optical path length within diamond ATR elements, the herein presented design combining bright tQCLs with a multi-reflection polycrystalline diamond (PCD) ATR element enables an optical beam path length of approximately 5 cm. Thereby, sensitive spectroscopic measurements in the MIR are enabled. As an example, non-invasive glucose monitoring in human saliva is examined, highlighting the potential benefits of the proposed analytical concept with regards to exquisite sensitivity and selectivity in combination with a robust sensing interface, i.e., diamond. This approach paves the way towards directly analyzing molecular constituents in complex and potentially corrosive biomedical and biochemical matrices. PMID- 30284571 TI - Metal binding functions of metallothioneins in the slug Arion vulgaris differ from metal-specific isoforms of terrestrial snails. AB - Arion vulgaris is a land-living European slug belonging to the gastropod clade of Stylommatophora. The species is known as an efficient pest organism in vegetable gardening and horticulture, which may in part be the consequence of its genetically based innate immunity, along with its high ability to withstand toxic metal stress by intracellular detoxification. Like many species of terrestrial snails, slugs possess a distinct capacity for Cd accumulation in their midgut gland, where the metal is stored and inactivated, conferring to these animals an increased metal tolerance. Although midgut gland Cd fractions in slugs have been shown to be variably allocated between different metal-binding protein pools, depending on the level of environmental metal contamination, a true metallothionein (MT) was so far never characterized from slugs. Instead, the Cd binding proteins identified so far were described as Metallothionein-like proteins (MTLPs). In the present study, the slug A. vulgaris was used as a model organism, in order to verify the presence of true MTs in experimentally metal exposed slugs. We wanted to find out if these suggested slug MTs have similar metal binding properties and metal-selective features like those previously reported from helicid snails. To this aim, two MT isoform genes (AvMT1 and AvMT2) were characterized from midgut gland extracts and localized in the cells of this tissue. The AvMT1 and AvMT2 proteins were purified and partially sequenced, and their metal-binding features analysed after recombinant expression. Eventually, we wanted to understand if and by how much the metal binding features of the two MT isoforms of A. vulgaris may be related, owing to their reciprocal amino acid sequence similarities, to the binding properties of metal-specific MTs from terrestrial snails.

AB - The purpose of this work is to study the influence of the substitution of Fe(ii) by Mn(ii) on the spin crossover behaviour of [FexMn1-x(L222N3O2)(CN)2].H2O solid solutions where L222N3O2 is a macrocyclic ligand = 2,13-dimethyl-6,9-dioxa 3,12,18-triazabicyclo[12.3.1]-octadeca-1(18),2,12,14,16-pentaene. The pure Fe(ii) complex is known to present a change of the coordination number from 7 at high temperature to 6 at low temperature. The target of the solid solution study was to investigate the effect of metal dilution on this coordination change. We have then measured the thermal spin crossover features as well as the metastable HS state lifetime generated by rapid thermal quenching, which was probed through the determination of the T(TIESST) value. A discussion of the spin-state as a function of temperature is given based on the phase diagram of this series and based on the investigation of the crystal structure of the [Mn(L222N3O2)(CN)2].H2O complex and its comparison with the published [Fe(L222N3O2)(CN)2].H2O master compound.

AB - Understanding how oral processing is altered in response to changes in the composition and mechanical properties of food provides useful information to design food with improved satiating capacity which is largely influenced by oral exposure. In turn, this information deepens the knowledge about the physiology of texture perception. Six yogurts were formulated with different amounts of protein and protein sources and addition of apple cubes: control (C), extra skimmed milk powder-added (MP), whey protein isolate-added (WPI), and whey protein microgels added (WPM). In addition, MP was also added with maltodextrin (MPMD) and with fresh apple cubes (MPF). Activities of masseter, anterior temporalis and anterior digastric muscles during oral processing of each sample were recorded (electromyography), and jaw movement amplitudes in three dimensions were determined (jaw tracking system). The jaw muscle activities were highly dependent on the type of yogurt. Addition of apple cubes (MPF) almost doubled the oral processing time, number of chews, and muscle activity of all samples. MP and MPMD required similar but lower values of oral processing than MPF attributed to their reinforced network of milk protein. The lowest values were found for WPI, C and WPM, indicating a weaker, more fluid material. These behavioral results, which clearly differentiate the samples, are discussed in connection to the rheological and sensory properties of the yogurts. This study suggests that adding apple cubes significantly alters the oral processing pattern, such that they may be a more effective way of increasing the oral processing time (time exposure) compared to more subtle changes in the protein amount or source. Nevertheless, changes in the protein amount and source also affected, although to a lesser extent, the behavioral, rheological, and sensory properties of yogurt. PMID- 30284576 TI - Metallothioneins of the urochordate Oikopleura dioica have Cys-rich tandem repeats, large size and cadmium-binding preference. AB - The increasing levels of heavy metals derived from human activity are poisoning marine environments, threating zooplankton and ocean food webs. To protect themselves from the harmful effects of heavy metals, living beings have different physiological mechanisms, one of which is based on metallothioneins (MTs), a group of small cysteine-rich proteins that can bind heavy metals counteracting their toxicity. The MT system of urochordate appendicularians, an ecologically relevant component of the zooplankton, remained, however, unknown. In this work, we have characterized the MTs of the appendicularian species Oikopleura dioica, revealing that O. dioica has two MT genes, named OdMT1 and OdMT2, which encode for Cys-rich proteins, the former with 72 amino acids comparable with the small size MTs of other organisms, but the second with 399 amino acids representing the longest MT reported to date for any living being. Sequence analysis revealed that OdMT2 gene arose from a duplication of an ancestral OdMT1 gene followed by up to six tandem duplications of an ancestral repeat unit (RU) in the current OdMT2 gene. Interestingly, each RU contained, in turn, an internal repeat of a 7-Cys subunit (X3CX3CX2CX2CX3-6CX2CXCX), which is repeated up to 12 times in OdMT2. Finally, ICP-AES analyses of heterologously expressed OdMT proteins showed that both MTs were capable to form metal-complexes, with preference for cadmium ions. Collectively, our results provide the first characterization of the MT system in an appendicularian species as an initial step to understand the zooplankton response to metal toxicity and other environmental stress situations. PMID- 30284577 TI - Emission of formic and acetic acids from two Colorado soils. AB - A 'missing source' of atmospheric formic acid is consistently observed during model-measurement comparisons, and evidence from multiple environments suggests a near-surface source. Soil emissions are considered to be a small formic acid source, but estimates are based on a single study from a tropical site. Here, we investigate soil emissions of organic acids from two soils - a ponderosa pine forest (Manitou Experimental Forest Observatory), and a managed lawn (Colorado State University) using a laboratory chamber. Both soils are a source of formic and acetic acids. Under ambient conditions, formic acid emissions are 0.11 (pine forest) and 0.15 (lawn) nmol m-2 s-1, and acetic acid emissions are 0.05 (pine forest) and 0.71 (lawn) nmol m-2 s-1. Only acetic acid emissions from the forest site correlate with CO2 fluxes, but all formic and acetic acid emissions increase exponentially with temperature. Increasing soil moisture only enhances acetic acid emissions from the forest. Considering this temperature and moisture dependence, we hypothesize that while equilibrium partitioning may contribute to the forest emissions, organic acid emissions from the lawn are likely driven by microbial activity. Lactic acid was emitted from both soils, but not quantified. The observed formic acid emissions are higher than previous measurements, but still low enough that soils are unlikely the 'missing source' of atmospheric organic acids, although the variability in the soil source is substantial. We contrast observations to previous parameterizations used in models, and present recommendations for modified parameterizations for formic and acetic acid emission. PMID- 30284579 TI - Knowledge and awareness of diabetes mellitus and its risk factors in Saudi Arabia. AB - OBJECTIVES: To summarize available peer-reviewed publications about public knowledge and awareness of diabetes mellitus (DM) among the population of Saudi Arabia. METHODS: We followed the standard reporting guidelines outlined in the PRISMA statement for the preparation of this systematic review. In February 2018 we conducted literature searches of PubMed, Scopus, BIOSIS Citation Index, and Web of Science using the following keywords: "Knowledge" OR "Awareness" AND "Diabetes Mellitus" AND "Saudi Arabia." Records were screened, and relevant studies were selected and synthesized narratively. RESULTS: Nineteen articles are included in our systematic review. These studies included the following populations: DM patients (n=13), healthcare workers (n=3), medical students (n=1), secondary school students (n=1), and general population (n=1). Most studies found a lack of public awareness of the risk factors and complications of DM. Among medical students and healthcare workers, knowledge about the epidemiology of the disease and angle of insulin injection was deficient. CONCLUSION: This review highlights the need for increased knowledge and awareness of DM among the Saudi population. The means of improving knowledge and awareness of DM needs to be integrated into existing healthcare systems and processes to better inform patients, families and communities about this chronic disease. PMID- 30284580 TI - The long-term outcomes and histological transformation in class II lupus nephritis. AB - OBJECTIVES: To examined the short and long-term outcome of class II lupus nephritis (LN). Methods: This retrospective study included patients with class II LN at their first renal biopsy between January 1996 and December 2016 in King Khaled University Hospital, Riyadh, Saudi Arabia. The rate of complete remission, worsening renal function, and histological transformation in the second biopsy were examined. Results: The study included 32 female patients with class II LN. The most frequent presentation (62.5% of patients) was hematuria with subnephrotic range proteinuria. The clinical presentation included acute kidney injury in 22% of patients, and 9.4% had nephrotic range proteinuria. Management with steroid monotherapy in 25 patients resulted in complete remission for 92% of these patients at 6 months. After a median follow up of 8 years, 2 patients had a doubling of their serum creatinine. During the follow up 17 patients (53%) needed a second biopsy, which revealed transformation to other classes (65%). Conclusions: Daily steroid monotherapy may be an appropriate first-line treatment for class II LN that presents with subnephrotic range proteinuria and normal kidney function. Patients with acute kidney injury and/or nephrotic range proteinuria may warrant more aggressive immunosuppressive regimens.

AB - OBJECTIVES: To determine the histopathological pattern of skin cancer in Madinah region of Kingdom of Saudi Arabia (KSA). Methods: This is a retrospective study including all cases with a histological diagnosis of skin cancer diagnosed at the Department of Pathology, King Fahad Hospital, Madinah, Saudi Arabia, between January 2006 and December 2017. Data included age, gender, site and histology of the tumor were collected from histopathological reports and analyzed using Statistical Package for the Social Sciences (SPSS) Version 21. Results: Among the 202 cancer cases studied in our series, there were 124 (61.4%) cases of basal cell carcinoma (BCC), 33 (16.3%) cases of squamous cell carcinoma (SCC), 14 (6.8%) cases of mycosis fungoides (MF), 12 (5.8%) cases of dermatofibrosarcoma protuberans (DFSP) and 7 (3.7%) cases of malignant melanomas (MM). The male to female ratio for all cases was 2.2:1. The ages ranged from 5 to 100 years with a mean age of 60.1+/-15 years. The peak age distribution was in the 60-69 year group. The most common site involved in BCC and SCC was the head and neck (92.7% and 66.7%) respectively). Acral distribution of MM was seen in 57.1% of the cases. Conclusion: Our data based on the histopathology history in the Madinah region match that in the world literature and Saudi national studies. PMID- 30284582 TI - Assessment of histopathological alterations in patients with chronic hepatitis B infection following long-term oral antiviral therapy. AB - OBJECTIVES: To evaluate the histopathological changes in the liver after oral antiviral therapy in patients with chronic hepatitis B. METHODS: A total of 79 HBeAg-negative and positive patients who had been on lamivudine, entecavir, or tenofovir disoproxil for at least 3 years prior to inclusion were enrolled between March 2015 and 2016, retrospectively. There were 23 patients on lamivudine, 21 patients on entecavir, and 35 on tenofovir. All patients underwent a follow-up liver biopsy. Biochemical, serological, virological and histopathological data were recorded in all patients and were compared after at least 3 years of treatment with oral antiviral agents. Results: Histological activity index scores were reduced in patients who received lamivudine (p=0.011), entecavir (p=0.002), and tenofovir (p=0.001). Also, in contrast with a significant improvement in fibrosis scores in lamivudine (p=0.033) and tenofovir (p=0.001) groups no improvements were found in patients who received entecavir (p=0.090). Conclusion: Long term treatment with oral antiviral agents was associated with biochemical, virological, serological, and histopathological improvements. Long-term use of anti-viral agents as well as continuous suppression of HBV DNA are prerequisites for histopathological improvement. PMID- 30284583 TI - Evaluation of the perfusion index according to the visual analog scale in postoperative patients. AB - OBJECTIVES: To evaluate the possible value of the perfusion index (PI) as a tool for pain assessment. Methods: This prospective, observational study was performed with 89 patients underwent surgery with general anesthesia. The patients with visual analog scale (VAS) greater than 3 were grouped as M1, and patients with VAS<=3 and performed morphine were grouped as M2. After surgery patients with VAS greater than 3 were given 2mg morphine. Patients with VAS greater than 3 were given increments of intravenous morphine (2 mg) at 20 minute intervals until VAS less than 3. The correlation and difference between PI and VAS score values were evaluated before and after analgesic administration. Results: Significant changes were found in both PI values and VAS scores between M1 and M2 groups (2.80+/ 0.77, 3.97+/-0.94, p less than 0.001; 6.60+/-1.20, 2.74+/-0.46, p less than 0.001) Despite no correlation was found between PI values and VAS scores of M1 and M2 groups, weak negative correlation was detected between differences in PI values and VAS scores among groups (r=-0.255, p=0.016). Conclusion: Perfusion index is a parameter that can be used in the assessment of postoperative pain and responses to analgesics. PMID- 30284584 TI - Can we use serum Anti-Mullerian hormone to differentiate the diagnosis between polycystic ovary syndrome patients and healthy women with polycystic ovarian morphology and regular menstrual cycles. AB - OBJECTIVES: To compare Anti-Mullerian hormone (AMH) concentrations between polycystic ovary syndrome (PCOS) patients and healthy women who have polycystic ovarian morphology (PCOM) with regular menstrual cycles, and to determine a diagnostic cutoff value for PCOS women during reproductive period. Methods: This study was carried out between February 2013 and October 2017 at the Department of Obstetrics and Gynecology, Izmir Katip Celebi University Ataturk Training and Research Hospital, Izmir, Turkey. Seventy PCOS patients and 70 PCOM women with normal menstrual cycles were included in the study. Blood samples of the subjects were obtained following an 8-hour fast for AMH and biochemical assessments, serum gonadotropin, and androgen measurements. Results: The mean serum AMH levels of PCOS patients were found to be higher than PCOM women with normal menstrual cycles (p less than 0.01). The optimal serum AMH cutoff value for PCOS diagnosis was determined as 3.51 ng/ml (sensitivity 72.8%, specificity 75.7%). Conclusion: Serum AMH concentrations are significantly higher in PCOS patients independent from the ovarian morphology and number of follicles per ovary. Positive and negative predictive values of AMH in PCOS diagnosis were found to be 75% and 73.6%, respectively, with a cutoff value of 3.51 ng/mL.

AB - Objectives To compare analgesia nociception index (ANI) values, visual analog scale (VAS) values, and hemodynamic parameters in hysteroscopy patients who received remifentanil and dexmedetomidine during general anesthesia. Methods: In total, 30 patients who underwent hysteroscopy between March and September 2016 at the University of Health Sciences Fatih Sultan Mehmet Health Research and Application Center, Ankara, Turkey were included in this prospective study. Standard hemodynamic monitoring, ANI, and bispectral index (BIS) monitoring were applied to the patients. At 10 min prior to induction, 1 MUg/kg of remifentanil was applied in Group R (n=15) and 1 MUg/kg of dexmedetomidine was applied in Group D (n=15). After induction, sevoflurane was used for maintenance with dexmedetomidine at 0.2-0.7 MUg/kg/hour in Group D and remifentanil at 0.05-0.5 MUg/kg/minute in Group R. Perioperative and postoperative analgesia levels (ANI and VAS, respectively), hemodynamics, and complications were recorded. Results: Even though the ANI levels in Group D were lower at the perioperative 5th and 10th minutes, the ANI values were between the targeted limits, except for the measurement after I-gel insertion, in both groups. Hemodynamic parameters were within normal limits, but the mean arterial pressures in Group R after induction, following I-gel placement, and at the perioperative 5th, 10th, and 20th minutes were lower and at postoperative 30th minute were significantly higher. Conclusion: Dexmedetomidine and remifentanil are both efficacious agents for perioperative analgesia in hysteroscopy cases. PMID- 30284586 TI - Effect of preoperative hydromorphone in patients undergoing laparoscopic radical gastrectomy. A double-blind, randomized and controlled trial. AB - OBJECTIVES: To determine the efficacy of preemptive hydromorphone for laparoscopic radical gastrectomy. Methods: The present prospective and double blinded study was performed in the The First Hospital, Jilin University, Changchun, China, between July 2017 and April 2018. Fifty patients scheduled for laparoscopic radical gastrectomy were equally randomized into 2 groups, which were administrated different drugs 10 minutes before surgery. Group P (the preemptive hydromorphone group) was administrated 2 mg hydromorphone (2 mL), and Group C (the control group) was administrated 2 mL normal saline intravenously. A standardized general anesthesia were conducted. Blood pressure and heart rate, postoperative morphine consumption, pain intensity, sedation status, and side effects were recorded. Results: Group C had larger intraoperative hemodynamic changes, higher postoperative visual analogue scale score, more morphine consumption and lower overall satisfaction degree than Group P. No difference was found between the 2 groups in sedation status and adverse effects. Conclusion: Preoperative 2 mg hydromorphone could reduce intraoperative changes of blood pressure and heart rate, postoperative pain intensity, and morphine consumption without an increase of adverse effects. PMID- 30284587 TI - Evaluation of the effects of different treatment modalities on angiogenesis in heart failure patients with reduced/mid-range ejection fraction via VEGF and sVEGFR-1. AB - OBJECTIVES: To investigate the clinical significance of VEGF, sVEGFR-1 in heart failure reduced ejection fraction (HFrEF) and heart failure mid-range ejection fraction (HFmrEF) patients. Methods: A total of 104 people consisting of HFrEF and HFmrEF patients (n=54) and healthy (n=50) subjects were included in this comparative cross-sectional study. The study took place in Gulhane Training and Research Hospital, Ankara, Turkey, between 2011 and 2013. Serum VEGF, sVEGFR-1, plasma pro-BNP analysis and transthoracic echocardiography were performed. Results: The average sVEGFR-1 level of the HFrEF and HFmrEF patients was significantly higher than the control group (0.185+/-0.122; 0.141+/-0.120; p=0.013). The average sVEGFR-1 level of the HFrEF and HFmrEF patients using beta blocker was significantly higher than the HFrEF and HFmrEF patients not using it (p=0.015). There was a significant and positive correlation between sVEGFR-1 and N-terminal pro-brain natriuretic peptide (pro-BNP) levels in the group with HF (r=0.211, p=0.044). Conclusion: It increases awareness about the role of sVEGFR-1 in HFrEF anf HFmrEF patients and the need for further studies. Beta-blocker may have a negative effect on angiogenesis in HFrEF and HFmrEF via increasing sVEGFR 1 levels. Additionally, Pro-BNP may contribute to inhibiting angiogenesis by increasing sVEGFR-1 levels and sVEGFR-1 may be an important biomarker in HFrEF and HFmrEF. PMID- 30284588 TI - High antimicrobial resistant rates among Gram-negative pathogens in intensive care units. A retrospective study at a tertiary care hospital in Southwest Saudi Arabia. AB - OBJECTIVES: To determine the distribution and resistance profiles of Gram negative bacteria (GNB) in intensive care units (ICUs) at King Abdullah Hospital in Bisha, Saudi Arabia. Methods: A record based retrospective study was conducted from December 2016 to January 2018. In total, 3736 non-duplicate clinical specimens from the general intensive care unit (ICU), neonatal ICU (NICU), and coronary CU (CCU) were analyzed for pathogens. Results: Of 3736 specimens, 9.6% (358) were positive for pathogens, and GNB constituted the majority (290/358; 81%). Acinetobacter is predominant in the general ICU, whereas Klebsiella pneumoniae is common in the NICU and CCU. Overall, GNB revealed a high resistance rate for cefuroxime (75.8%) trimethoprim/sulfamethoxazole (73.4%), cefotaxime (72.9%), aztreonam (64.6%), piperacillin (62.1%), and ciprofloxacin (61.5%). Acinetobacter revealed a high resistance (93.4% to 97.5%) to all antimicrobials except colistin (4%). Klebsiella pneumoniae showed a high resistance to trimethoprim/sulfamethoxazole (71.8%), cefotaxime (71.4%) and aztreonam (65.2%). Pseudomonas aeruginosa showed good activity for aminoglycosides but increasing resistance for cephalosporins and meropenem. GNB exhibited a high rate of multi drug-resistant (MDR) phenotypes (67.9%) with a higher level among Acinetobacter spp. (97.5%). There were no significant differences in the resistance rates of GNB from different ICUs except for imipenem (p=0.002) and ciprofloxacin (p=0.003). Conclusions: Increased antimicrobial resistance with high proportions of MDR patterns were found among GNB from ICUs. Comprehensive surveillance programs are needed to track the origins and emergence pathways of resistant pathogens. PMID- 30284589 TI - The importance of hand hygiene education on primary schoolgirls' absence due to upper respiratory infections in Saudi Arabia. A cluster randomized controlled trial. AB - OBJECTIVES: To quantify the reduction in absence due to upper respiratory infections (URIs) among primary schoolgirls attending Riyadh's schools after delivering a hand hygiene workshop intervention over a period of 5 weeks. Methods: A cluster randomized trial was conducted among girls attending 4 primary schools between January and March 2018. The participants attended a hand hygiene workshop. The schoolgirls' absences were followed up for 5 weeks. Incidence rate, percentage of absence days, and absence rate were calculated for total and URIs absences. Result: Total number of participating schoolgirls was 496. Upper respiratory infections accounted for 15.3% of absence episodes. Schoolgirls lost 521 days of school and 19.4% of them were URIs-related. Absence rate due to URIs were 12.4 and 23.4 as well as 5.62 and 11.72 per 100 schoolgirls in the control (CG) and experimental (EG) groups, respectively. Percentage of absence days were lower in the experimental group (CG: 0.86% and 1.39% versus EG: 0.39% and 0.72%). Incidence rates of absence due to URIs were 0.54 and 1.02 in CG versus 0.24 and 0.51 in EG per 100 schoolgirls per day. Conclusion: There could be further reduction in school absences if education was accompanied by hand soap dissemination. The study could serve as a pilot for major studies in the future. Sustainability of the intervention can be tested in studies with longer durations. PMID- 30284590 TI - Staphylococcus lugdunensis from gluteal abscess to destructive native triple valve endocarditis. AB - We herein present the case of a 43-year-old male diabetic patient who presented with an aggressive form of infective endocarditis involving the tricuspid, mitral and aortic valves following a gluteal abscess due to infection with Staphylococcus lugdunensis. This coagulase-negative organism which is generally considered a component of the normal flora of the skin has however recently emerged as an unusually virulent pathogen responsible for both nosocomial and community-acquired infections. The case demonstrates the importance of paying utmost attention and ensuring a logical conclusion to the identification of persistent coagulase-negative blood cultures. In addition, it also shows the importance of early identification of this organism and aggressive antibiotic administration to avert endocarditis because of the unusual virulence of the organism. Staphylococcus lugdunensis is rarely a clinical specimen contaminant, and its isolation warrants further investigation and concerted treatment.

PMID- 30284595 TI - Oral administration of oat beta-glucan preparations of different molecular weight results in regulation of genes connected with immune response in peripheral blood of rats with LPS-induced enteritis. AB - PURPOSE: Beta-glucans are biologically active polysaccharides having antioxidant, immunomodulatory, and antiinflammatory properties. This study investigated the transcriptomic profile in peripheral blood of rats with LPS-induced enteritis, which were fed a diet supplemented with high- (G1) and low- (G2) molecular-weight oat beta-glucans. METHODS: Two-color rat gene expression microarrays were applied and the analysis was performed using a common reference design to provide easy means of comparing samples from various experimental conditions against one another. Common reference sample was labeled with cyanine 3 (Cy3) and investigated samples from each experimental group: C-G0 (control group fed semi synthetic diet), LPS-G0 (LPS-challenged group fed semi-synthetic diet), LPS-G1 (LPS-challenged group fed G1 beta-glucan enriched diet), and LPS-G2 (LPS challenged group fed G2 beta-glucan enriched diet) were labeled with cyanine 5 (Cy5). Each microarray was performed in quadruplicate. Statistical analysis was performed using one-way ANOVA and Tukey's HSD post-hoc test (p < 0.05). A multiple testing correction was performed using Benjamini and Hochberg False Discovery Rate < 5%. A quantitative real-time RT-PCR was performed to verify the expression of chosen transcripts. RESULTS: The microarray analyses revealed differentially expressed transcripts between: the LPS-G0 and the control groups: C-G0 (138 genes), the LPS-G1 and LPS-G0 groups (533 genes), and the LPS-G2 and LPS-G0 groups (97 genes). Several differentially expressed genes in the beta glucan-supplemented groups encoded proteins belonging to TLR and NLR signaling pathways, as well as prostaglandin synthesis and regulation pathways. Both beta glucans up-regulated the expression of Atg10, which belongs to the family of autophagy-related genes, suggesting a possible link between autophagy induction and beta-glucan supplementation. CONCLUSION: The changes in gene expression observed in the peripheral blood indicate that oat beta-glucans exerted a protective effect in rats with an induced inflammatory state caused by LPS challenge. The greater number of differentially expressed genes was observed in group supplemented with G1 beta-glucan, pointing at the differences in the mode of action of high- and low-molecular-weight beta-glucans in the organism. PMID- 30284596 TI - Effects of MDPV on dopamine transporter regulation in male rats. Comparison with cocaine. AB - RATIONALE: MDPV (3,4-methylenedioxypyrovalerone) is a synthetic cathinone present in bath salts. It is a powerful psychostimulant and blocker of the dopamine transporter (DAT), like cocaine. It is known that acute exposure to psychostimulants induces rapid changes in DAT function. OBJECTIVES: To investigate the effects of MDPV on DAT function comparing with cocaine. METHODS: Binding of [3H]WIN 35428 was performed on PC 12 cells treated with MDPV and washed. Rat striatal synaptosomes were incubated with MDPV or cocaine (1 MUM) for 1 h and [3H]dopamine (DA) uptake was performed. Also, different treatments with MDPV or cocaine were performed in Sprague-Dawley rats to assess locomotor activity and ex vivo [3H]DA uptake. RESULTS: MDPV increased surface [3H]WIN 35428 binding on PC 12 cells. In vitro incubation of synaptosomes with MDPV produced significant increases in Vmax and KM for [3H]DA uptake. In synaptosomes from MDPV (1.5 mg/kg, s.c.) and cocaine- (30 mg/kg, i.p.) treated rats, there was a significantly higher and more persistent increase in [3H]DA uptake in the case of MDPV than cocaine. Repeated doses of MDPV developed tolerance to this DAT upregulation and 24 h after the 5-day treatment with MDPV, [3H]DA uptake was reduced. However, a challenge with the same drugs after withdrawal recovered the DAT upregulation by both drugs and showed an increased response to MDPV vs the first dose. At the same time, animals were sensitized to the stereotypies induced by both psychostimulants. CONCLUSIONS: MDPV induces a rapid and reversible functional upregulation of DAT more powerfully and lasting than cocaine. PMID- 30284597 TI - Interaction potential of the dual orexin receptor antagonist ACT-541468 with CYP3A4 and food: results from two interaction studies. AB - PURPOSE: ACT-541468 is a novel dual orexin receptor antagonist (DORA) under development for the treatment of insomnia. In vitro studies suggested a significant role of CYP3A4 in ACT-541468 metabolism and an impact on CYP3A4 activity. METHODS: Subsequently, two clinical cross-over studies investigated the victim (n = 14 healthy subjects) and perpetrator (n = 20) potential of 25 mg ACT 541468 with respect to CYP3A4. The effect of food intake on the pharmacokinetics of ACT-541468 was also investigated. RESULTS: Moderate CYP3A4 inhibition by diltiazem (240 mg/day) increased the Cmax and AUC0-infinity of ACT-541468 by 1.4 fold (90% confidence interval (CI): 1.2-1.6) and 2.4-fold (90% CI: 2.0-2.8), respectively, and prolonged t1/2 by 80% (90% CI: 60-90) without affecting tmax. Single- and multiple-dose administration of 25 mg ACT-541468 had no impact on the pharmacokinetics of the sensitive substrate midazolam and its main metabolite 1 hydroxy midazolam indicated by 90% CI of the geometric mean ratios of Cmax and AUC within bioequivalence criteria and by an unchanged tmax. After a high-fat high-calorie breakfast, the pharmacokinetic profile of 25 mg ACT-541468 showed a decrease of Cmax by 24% (90% CI: 17-31) and a delay of tmax by approximately 2 h (90% CI: 1.4-2.4), whereas t1/2 and AUC0-24 remained essentially unchanged. ACT 541468 given alone or in combination with diltiazem, midazolam, or food was safe and well tolerated. CONCLUSIONS: Overall, ACT-541468 has been determined as CYP3A4 substrate but without any perpetrator drug-drug interaction potential regarding CYP3A4 in humans. Food affected ACT-541468 absorption without modifying overall exposure. PMID- 30284598 TI - [What is verified for travel vaccinations?] AB - Vaccinations are among the most effective preventive measures modern medicine has to offer. They lead both to individual protection in those vaccinated and in many cases to the protection of others against transmission of the infection; however, the acceptance of vaccinations in Germany has declined rather than increased in recent years. Paradoxically, this is very much due to the success of the vaccinations: due to successful immunization campaigns, numerous diseases have become so rare that they have disappeared from the consciousness of the population. Travel medicine counselling offers an excellent opportunity to fill in gaps in immunization. PMID- 30284599 TI - Psychometric validation of the self-identification of having a mental illness (SELF-I) scale and the relationship with stigma and help-seeking among young people. AB - PURPOSE: Self-identification of having a mental illness has been shown to be an important factor underpinning help-seeking behaviour and may mediate the relationship between personal stigma and mental health service use. This study validates a new scale for the self-identification of having a mental illness among a non-clinical, community cohort of young people in the UK. METHODS: Following consultation with a group of young person experts with experience of mental health problems, we evaluated the psychometric properties of the self identification of mental illness scale (SELF-I) among 423 young people aged 13-24 years who are part of an ongoing prospective community cohort. We performed test retest reliability among a subset of 53 participants. Psychometric validation for the scale used measures of Cronbach's alpha and Pearson's correlation coefficient. Item performance was assessed along and in relation with each covariate. RESULTS: The SELF-I demonstrated robust psychometric properties including high test-retest reliability (0.95) and good internal consistency (0.87 as determined by the Cronbach's alpha). The inter-total correlations for each item, which ranged from 0.62 to 0.74, supported keeping all items in the scale. Reporting greater psychiatric symptomatology via the SDQ (beta: 0.82 95% confidence interval 0.40, 1.23), psychotic-like experiences (beta: 0.37 95% confidence interval 0.14, 0.59), and use of mental health services (beta: 0.92 95% confidence interval 0.71, 1.13) were associated with a greater self perception as having a mental illness (p < 0.05), providing evidence of convergent validity. As expected, we found that less intended stigmatising behaviour was associated with greater self-perceptions of having a mental illness (B: 0.18, 95% CI 0.07, 0.28). CONCLUSIONS: The SELF-I scale provides a method to gather insight into how young people, who may not identify as service users, perceive their own mental state and potential risk for developing a mental illness. This can be important for understanding perceived need for help and likelihood of using services among those with mental health problems.

AB - Microorganisms play important roles in mangrove ecosystems. However, we know little about the ecological implications of mangrove microbiomes for high productivity and the efficient circulation of elements in mangrove ecosystems. Here, we focused on mangrove sediments located at the Yunxiao National Mangrove Reserve in southeast China, uncovering the mangrove microbiome using the 16S rRNA gene and shotgun metagenome sequencing approaches. Physicochemical assays characterized the Yunxiao mangrove sediments as carbon (C)-rich, sulfur (S)-rich, and nitrogen (N)-limited environment. Then phylogenetic analysis profiling a distinctive microbiome with an unexpected high frequency of Chloroflexi and Nitrospirae appeared to be an adaptive characteristic of microbial structure in S rich habitat. Metagenome sequencing analysis revealed that the metabolic pathways of N and S cycling at the community-level were routed through ammonification and dissimilatory nitrate reduction to ammonium for N conservation in this N-limited habitat, and dissimilatory sulfate reduction along with polysulfide formation for generating bioavailable S resource avoiding the biotoxicity of sulfide in mangrove sediments. In addition, methane metabolism acted as a bridge to connect C cycling to N and S cycling. Further identification of possible biogeochemical linkers suggested Syntrophobacter, Sulfurovum, Nitrospira, and Anaerolinea potentially drive the coupling of C, N, and S cycling. These results highlighting the adaptive routed metabolism flow, a previously undescribed property of mangrove sediment microbiome, appears to be a defining characteristic of this habitat and may significantly contribute to the high productivity of mangrove ecosystems, which could be used as indicators for the health and biodiversity of mangrove ecosystems. PMID- 30284603 TI - A phase II study of NK012, a polymeric micelle formulation of SN-38, in unresectable, metastatic or recurrent colorectal cancer patients. AB - PURPOSE: NK012 is a polymeric micelle formulation of SN-38, the active metabolite of irinotecan. We evaluated the efficacy and safety of NK012 in Japanese patients with unresectable metastatic colorectal cancer. METHODS: We conducted a multicenter open-label phase II trial of NK012 monotherapy in 58 patients who had been treated with an oxaliplatin-based chemotherapy regimen (group A: 53 patients with UGT1A1 genotype -/-, *6/-, or *28/-; group B: 5 patients with UGT1A1 genotype *6/*28 or *6/*6). The primary endpoint was the response rate (RR). Initial doses of 28 and 18 mg/m2 for group A and group B, respectively, were administered intravenously over 30 min, and these doses were subsequently administered every 3 weeks. Group A was evaluated as the primary efficacy population, while group B was evaluated for reference. RESULTS: In group A, the RR was 3.8%, and the median progression-free survival and overall survival were 3.30 months and 15.03 months, respectively. In both groups, the most common grade >= 3 adverse drug reaction (ADR) was neutropenia and the incidence of grade >= 3 diarrhea was low or zero. In group A, 17 serious ADRs were observed in 10 patients (17%); all improved or recovered. In group B, no serious ADRs were observed. No treatment-related deaths were reported in either group. CONCLUSIONS: NK012 monotherapy yielded an RR similar to the RR of irinotecan monotherapy that was reported in the phase III EPIC trial (4.2%), and the incidence of grade >= 3 diarrhea was low. Based on the incidence and severity of febrile neutropenia and grade >= 3 neutropenia, the initial dose of NK012 28 mg/m2 may be too high for colorectal cancer patients who have previously been treated with an oxaliplatin based chemotherapy regimen.

PMID- 30284605 TI - Combined host-guest complex with coffee-ring effect for constructing ultrasensitive SERS substrate for phenformin hydrochloride detection in healthcare products. AB - Phenformin hydrochloride (PHE), once used as a traditional anti-diabetic drug, has now been banned due to significant side effects. However, the phenomenon of the illegal addition of PHE to hypoglycemic healthcare products is still rampant. Thus, the detection of illegally added PHE is urgently needed. Surface-enhanced Raman scattering (SERS) is a promising candidate for this purpose, but the weak affinity between PHE and bare metal (Au or Ag) limits direct SERS detection of PHE. In this paper, we prepared Ag nanoparticles coated with beta-cyclodextrin (AgNP@beta-CD), which display the coffee-ring effect, that can be used for PHE sensing. beta-CD-functionalized nanoparticles could capture the analyte and fix the molecular orientation in the hydrophobic cavity. The coffee-ring effect could improve the SERS effect through a higher concentration of the analyte, higher density of nanoparticles, and more hot spots. The SERS performance of the AgNP@beta-CD substrate was characterized by using o-phenylenediamine dihydrochloride as a probe molecule. The excitation wavelength and pH value were optimized. A linear response for PHE detection is in the 7.0 * 10-8-1.0 * 10-6 mol L-1 concentration range, and the limit of detection is as low as 8.0 * 10-9 mol L-1. This AgNP@beta-CD coffee-ring effect substrate was applied to the detection of PHE in healthcare products, with recoveries between 95.3 and 105.0% and relative standard deviations of less than 5.16%. It is anticipated that the AgNP@beta-CD substrate will also have great potential for the monitoring of other aromatic drugs in healthcare products. PMID- 30284606 TI - Fractures in patients with osteopetrosis, insights from a single institution. AB - PURPOSE: Osteopetrosis is a hereditary skeletal disorder in which defective osteoclast function leads to abnormally hard and brittle bones. This study aims to describe the pattern of fractures occurring in this group of patients, possible complications, and strategies to avoid them. METHODS: This is a case series of six osteopetrotic patients with a total of 12 fractures managed in our institution over a period of nine years. Patient records were also reviewed for complications both intra- and post-operatively. RESULTS: The majority of the fractures involved the femur, with three of these being peri-implant in nature. Other bones involved include the tibia, humerus, patella, fifth metatarsal, and proximal phalanx of the toe. There was a high rate of complications while managing these patients: three patients had peri-implant stress fractures, three with retained broken screws, and one case each of delayed union, non-union, and surgical site infection. CONCLUSION: Osteopetrosis fractures present a unique challenge to the orthopedic surgeon. Careful pre-operative planning should be undertaken before proceeding with surgery in these cases. PMID- 30284607 TI - The anterior-based muscle-sparing approach to the hip: the "other" anterior approach to the hip. AB - PURPOSE: The purpose of this study was to evaluate safety, efficacy, and learning curves of anterior-based muscle-sparing total hip arthroplasty (ABMS-THA) in the supine position. Furthermore, early functional outcome was evaluated and compared to direct anterior approach (DAA) by measuring surface electromyography (sEMG). METHODS: We present a prospective cohort study of 343 hips. The safety and learning curve were assessed by recording operative time and peri-operative adverse events. For assessment of efficacy, functional and radiological outcomes were evaluated. A selected group of 32 patients have been studied by sEMG and compared to a matched group of 32 patients who received a THA using DAA approach. RESULTS: There was one dislocation (0.3%); two (0.6%) patients had an intra operative fractures of the greater trochanter; two patients (0.6%) experienced a self-limited femoral nerve palsy. Physical therapy milestones for hospital discharge were reached on an average of 1.7 days. sEMG showed that ABMS and DAA have a similar muscle recruitment pattern and functional recovery after THA. One patient was revised for infection, 16 were lost, and 326 hips were available with a median follow-up of 42 months (range 24-60). The mean Harris Hip Score (HSS) increased from 44.3 to 91.9. Ninety-six percent of the hips had a leg length discrepancy (LLD) < 5 mm. There were no radiological signs of mechanical loosening or osteolysis. CONCLUSIONS: The ABMS approach in the supine position is clinically effective and safe; special advantages include a very low dislocation rate and a great control of LLD. PMID- 30284608 TI - Dynamics of WNT signaling components in the human ovary from development to adulthood. AB - WNT signaling has been shown to play a pivotal role in mammalian gonad development and sex differentiation; however, its role in the developing human ovary has not been investigated. We analyzed a quantitative mass spectrometry dataset to determine the expression of WNT signaling components between 47 and 137 days of development and in adult ovarian cortex tissue. WNT signaling was identified within the top ten canonical pathways of proteins detected at every developmental stage examined. We further examined the specific localization of WNT signaling components glycogen synthase kinase 3 (GSK3B), frizzled 2 (FZD2), and beta-catenin (CTNNB1) within ovarian tissue. GSK3B was nearly ubiquitously expressed during fetal development, while FZD2 was specific to germ cell nests during early development. beta-catenin exhibited translocation from primarily membrane bound during early ovarian development to cytoplasmic and nuclear staining specifically in early primordial follicles in the fetal ovary. This cytoplasmic and nuclear beta-catenin persisted in primordial follicles in adult ovarian tissue, but returned to membrane-bound localization in secondary follicles. We conclude that WNT signaling components are expressed in the human ovary from early to mid-gestation and remain in the adult ovary, and observed evidence for canonical WNT signaling only in the oocytes of primordial follicles. Together, these data are indicative of a role for canonical WNT signaling via beta-catenin nuclear translocation during human follicle formation and follicle maintenance. PMID- 30284609 TI - Anisomycin, a JNK and p38 activator, suppresses cell-cell junction formation in 2D cultures of K38 mouse keratinocyte cells and reduces claudin-7 expression, with an increase of paracellular permeability in 3D cultures. AB - Keratinocytes in the oral mucosal epithelium, which is a non-keratinized stratified epithelium, are exposed to various stimuli from the oral cavity. JNK and p38 are stress-activated mitogen-activated protein kinases (MAPKs) that are phosphorylated by various stimuli and are involved in the assembly and disassembly of tight junctions (TJs) in keratinocytes. Therefore, we investigated the effects of stress-activated MAPKs on TJs in a mouse keratinocyte cell line during cell-cell junction formation in two-dimensional (2D) cultures or stratification to form non-keratinized epithelium in 3D cultures. In 2D cultures, calcium induced zipper-like staining for ZO-1 at 2 h and string-like staining for ZO-1 at 12 h, which indicated immature and mature cell-cell junctions, respectively. Anisomycin (AM), a JNK and p38 activator, inhibited formation of string-like staining for ZO-1, whereas inhibition of JNK, but not p38, after AM treatment restored string-like staining for ZO-1, although claudins (CLDNs) 4, 6, and 7 did not completely colocalize to ZO-1-positive sites. In 3D cultures, AM treatment for 2 weeks activated only p38, suppressed flattening of the superficial cells, removed CLDN7 from ZO-1-positive spots on the surface of 3D cultures, which represent TJs, and decreased transepithelial electrical resistance. Thus, short-term AM treatment inhibited maturation of cell-cell junctions by JNK, but not p38, activation. p38 activation by long-term AM treatment affected morphology of stratified structures and paracellular permeability, which was increased by CLDN7 removal from TJs. Various chronic stimuli that activate stress-activated MAPKs may weaken the keratinocyte barrier and be involved in TJ-related diseases. PMID- 30284610 TI - Morphological characteristics of optical coherence tomography defined plaque fissure in patients with acute coronary syndrome. AB - We assessed the plaque disruption in 245 consecutive patients with acute coronary syndrome undergoing percutaneous coronary intervention. The plaque fissure was diagnosed with optical coherence tomography, and intravascular ultrasound was used to determine arterial remodeling. Of them, 26 fissures were found in this study. The definite fissure was seen in 17 (65.4%) and probable fissure was seen in 9 (34.6%) patients. In 18 (69.2%), plaque fissure component was lipidic or thin-capped fibroatheroma. Eighteen (69.2%) of fissured plaque were seen within 30 mm of coronary ostium. Combined plaque fissure with plaque rupture/erosion was seen in 21 (80.8%) cases. The isolated fissure was seen in 5 (19.2%). Compared to the maximal necrotic core site of the ruptured plaque, the fissure site showed a smaller %necrotic core (p = 0.012), however, greater in fissure site than minimal lumen area site (24.93 +/- 11.50% vs 15.34 +/- 10.40%, p < 0.0001). The remodeling index was higher at fissure site as compared to minimal lumen area site (1.02 +/- 0.22 vs 0.94 +/- 0.27; p = 0.047), but similar to the rupture plaque (p = 0.31). The frequency of positive remodeling was 34.6% (9/26) at the plaque fissure. Although the plaque fissure can be interchangeable with the rupture in acute coronary syndrome, the limited extension to the small lipid core might and less positive remodeling provoke a fissuring of the plaque. Further study is necessary to assess the plaque fissure. PMID- 30284612 TI - Advancing EJNMMI: continuing success and next developments. PMID- 30284611 TI - Progression of ductal carcinoma in situ to invasive breast cancer: comparative genomic sequencing. AB - Several models have been described as potential mechanisms for the progression of ductal carcinoma in situ (DCIS) to invasive breast cancer (IBC). The aim of our study was to increase our understanding of DCIS progression by using massive parallel sequencing of synchronous DCIS and IBC. We included patients with synchronous DCIS and IBC (n = 4). Initially, IBC and normal tissue were subjected to whole exome sequencing. Subsequently, targeted sequencing was performed to validate those tumor-specific variants identified by whole exome sequencing. Finally, we analyzed whether those specific variants of the invasive component were also present in the DCIS component. There was a high genomic concordance between synchronous DCIS and IBC (52 out of 92 mutations were present in both components). However, the remaining mutations (40 out of 92) were restricted to the invasive component. The proportion of tumor cells with these mutations was higher in the invasive component compared to the DCIS component in a subset of patients. Our findings support the theory that the progression from DCIS to IBC could be driven by the selection of subclones with specific genetic aberrations. This knowledge improves our understanding of DCIS progression, which may lead to the identification of potential markers of progression and novel therapeutic targets in order to develop a more personalized treatment of patients with DCIS.

AB - BACKGROUND: Pre-peritoneal pelvic packing (PPP) is a technique used for treating pelvic hemorrhage in patients with pelvic fractures and hemodynamic instability after a high-energy trauma representing a life-threatening situation. The aim of this study was to perform a comprehensive review of the literature. METHODS: A review of the medical literature was performed, based on the following inclusion criteria: patients sustaining pelvic fractures with hemodynamic instability and the inclusion of PPP as a tool for hemorrhage control. Articles not involving human patients, review articles, surveys, pediatric patients, hemodynamic stability, case reports, and not directly related publications; such as angiography with or without embolization, and REBOA use for hemorrhage control as a primary outcome evaluation were excluded from this search. RESULTS: Eleven articles out of seventy-seven identified publications between 2008 and 2018 met the inclusion criteria and were included in this review. CONCLUSIONS: PPP is a surgical approach used in life-threatening situations due to pelvic fracture with high risk of death for exsanguination. Performed expediently, good results can be obtained with a decrease in the need for blood products, improved systolic blood pressure, and a decrease in mortality rates overall. This makes PPP an important life-saving tool.

AB - Geriatric syndromes are the pathognomonic columns of geriatric medicine. In contrast to many syndromes in younger people, in geriatric patients, the chief complaint does not typically represent the specific pathological condition underlying the change in health status. Geriatric syndromes are usually highly prevalent, multicausal and share a number of common risk factors. In recent years, scientific controversy over anemia in the aged has revealed a high prevalence in geriatric patients, which prompted the "working group on anemia" to publish its first position paper at a European level. The development of anemia is multicausal and the causes of the various forms of anemia range from iron deficiency, malnutrition, chronic inflammation, hormonal dysregulation, functional organ disorders, impaired synthesis to malignancies. The corresponding pathomechanisms are closely associated with the development of other geriatric syndromes such as gait disorders, sarcopenia, frailty, and falls. Against this backdrop, the "working group on anemia" of the German Geriatric Society has devised a second position paper:"Multicausality and the significant association between anemia and assessment-based quantifiable impairments suggest the consideration of anemia in the aged to be a geriatric syndrome." PMID- 30284615 TI - Establishment of Fascioloides magna in a new region of Hungary: case report. AB - During the monitoring of red deer (N = 124) and fallow deer (N = 13) populations in four neighbouring areas, the presence of Fascioloides magna was confirmed in southwestern Hungary. The prevalence and the mean intensity of the infection within the host populations ranged between 0 and 100% and 0-36.3, respectively. The determined prevalences are similar to that observed earlier in other European natural foci. The authors hypothesise that the appearance of F. magna in this region should have been a partly natural- and partly human-influenced process. PMID- 30284616 TI - Negative covariance between water mite and gregarine parasitism for adult dragonflies, Leucorrhinia intacta (Hagen): an age-related pattern? AB - Studies on parasite-mediated selection often focus on single parasite taxa infecting single species of hosts. However, host populations experience infections by multiple parasite taxa simultaneously; coinfection is expected to influence how host- and/or parasite-related factors affect host exposure and susceptibility to various parasites, and the resulting patterns of infection. We sampled adult dragonflies from a population of Leucorrhinia intacta (Hagen) in eastern Ontario, Canada. Dragonflies were exposed to parasitism by both water mites (Arrenuridae) and gregarines (Eugregarinidae). We tested for covariation between these ecto- and endoparasites, while considering potential sex and age biases in host sampling and patterns of infection. Mite parasitism differed dramatically between host sexes: nearly all collected males were parasitized, whereas only half of females were infested. This was likely due to differences in age distributions between sexes in sampled dragonflies. Water mite and gregarine parasitism showed strong, negative covariation, and coinfection occurred far less often than expected by chance, although these patterns were restricted to samples of females which, unlike male samples, likely included many old and young dragonflies. We report the first observation of negative covariation between internal and external parasite taxa in an anisopteran host and suggest this relationship between water mites and gregarines may be more widespread among Odonata and perhaps other insects than previously surmised. We advance hypotheses based on host age-parasitism relationships as well as variable parasite-mediated selection to help explain the sex specificity of observed coinfection patterns in our samples. PMID- 30284617 TI - Clinical significance of hepatic steatosis according to coronary plaque morphology: assessment using controlled attenuation parameter. AB - BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) plays a significant role in coronary atherosclerosis, independent of shared metabolic risk factors. The measurement of the controlled attenuation parameter (CAP) has shown to allow early and noninvasive detection of NAFLD at subclinical stage. We evaluated the significance of CAP-defined NAFLD in association with the presence of any type of coronary plaques and different plaque compositions. METHODS: We conducted a retrospective cohort of apparently healthy subjects who had liver Fibroscan and coronary computed tomography during health screening exams. RESULTS: A greater number of subjects with CAP-defined NAFLD was found in group with coronary plaques (61.3% vs. 73.5%, p = 0.005 without vs. with any type of plaque). From multivariate regression model, CAP >= 222 dB/m was an independent and significant parameter associated with the presence of coronary plaques, after adjusting possible confounders (OR 1.624, 95% 1.047-2.518, p = 0.030). Interestingly, CAP >= 222 dB/m was significantly associated with non-calcified plaque (adjusted OR 3.528, 95% CI 1.463-8.511, p = 0.005), whereas it was not significant in calcified plaques (p = 0.171). CONCLUSION: CAP-defined NAFLD is independently associated with coronary plaques, especially non-calcified plaques. The association between NAFLD and non-calcified plaques suggests that particular attention should be given to the subjects with NAFLD for primary prevention. PMID- 30284618 TI - Diabetes mellitus induced by PD-1 and PD-L1 inhibitors: description of pancreatic endocrine and exocrine phenotype. AB - AIMS: Programmed cell death-1 and programmed death ligand 1 (PD-1/PD-L1) inhibitors restore antitumor immunity, but many autoimmune side-effects have been described. Diabetes mellitus is a rare complication, and little data concerning its pathophysiology and phenotype have been published. This study aimed to describe both pancreatic endocrine and exocrine functions, immunological features and change in pancreas volume in subjects with diabetes mellitus induced by PD-1 and PD-L1 inhibitors. METHODS: We analyzed the data of six subjects treated with immunotherapy who presented acute diabetes. RESULTS: There were five men and one woman. Median age was 67 years (range 55-83). Three subjects were treated with nivolumab, two with pembrolizumab and one with durvalumab. Median time to diabetes onset after immunotherapy initiation was 4 months (range 2-13). Four patients presented fulminant diabetes (FD); none of these had type 1 diabetes (T1D)-related autoantibodies, none of them had T1D or FD-very high-risk HLA class II profiles. The bi-hormonal endocrine and exocrine pancreatic failure previously reported for one FD patient was not found in other FD subjects, but glucagon response was blunted in another FD patient. Pancreas volume was decreased at diabetes onset in 2 FD patients, and all patients presented a subsequent decrease of pancreas volume during follow-up. CONCLUSIONS: In the patients presented herein, immunotherapy-induced diabetes was not associated with T1D-related autoantibodies. The hormonal and morphological analysis of the pancreatic glands of these six cases contributes to the understanding of the underlying and probably heterogeneous mechanisms. There is a need to find biomarkers to identify patients at risk to develop these new forms of diabetes at early stages of the process to prevent ketoacidosis and to evaluate preventive strategies. PMID- 30284619 TI - Glyphosate induces the synthesis of ppGpp. AB - Glyphosate, the most widely used herbicide in both agricultural and urban areas is toxic for plants and for many bacterial species. The mechanism of action of glyphosate is through the inhibition of the EPSP synthase, a key enzyme in the biosynthetic pathway of aromatic amino acids. Here we show that glyphosate induces the stringent response in Escherichia coli. Bacteria treated with glyphosate stop growing and accumulate ppGpp. Both growth arrest and ppGpp accumulation are restored to normal levels upon addition of aromatic amino acids. Glyphosate-induced ppGpp accumulation is dependent on the presence of the (p)ppGpp synthetase RelA. However, unlike other cases of amino acid starvation, pppGpp could not be discerned. In a gppA background both ppGpp and pppGpp accumulated when exposed to glyphosate. Conversely, the wild-type strain and gppA mutant treated with serine hydroxamate accumulated high levels of both ppGpp and pppGpp. Altogether, the data indicate that glyphosate induces amino acid starvation resulting in a moderate accumulation of ppGpp and a reversible stringent response. PMID- 30284620 TI - Disadvantages of a weight estimation formula for macrosomic fetuses: the Hart formula from a clinical perspective. AB - PURPOSE: Sonographic fetal weight (FW) estimation to detect macrosomic fetuses is an essential part of everyday routine work in obstetrics departments. Most of the commonly used weight estimation formulas underestimate FW when the actual birth weight (BW) exceeds 4000 g. One of the best-established weight estimation formulas is the Hadlock formula. In an effort to improve the detection rates of macrosomic infants, Hart et al. published a specially designed formula including maternal weight at booking. The usefulness of the Hart formula was tested. METHODS: Retrospective study of 3304 singleton pregnancies, birth weight >= 3500 g. The accuracy of the Hadlock and Hart formula were tested. A subgroup analysis examined the influence of the maternal weight. The Chi-squared test and one-way analysis of variation were carried out. For all analyses, p < 0.05 was considered statistically significant. RESULTS: The overall percentages of births falling within +/- 5% and +/- 10% of the BW using the Hadlock formula were 27% and 53%, respectively. Using the Hart formula, 24% and 54% were identified within these levels. With the Hart formula, 94% of all weight estimations fall within 4200 g +/- 5% and nearly 100% fall within 4200 g +/- 10%. CONCLUSIONS: Applying the Hart formula results in an overestimation of fetal weight in neonates with a birth weight < 4000 g and fails to identify high-risk fetuses. We, therefore, do not consider Hart's formula to be of clinical relevance. PMID- 30284621 TI - The differences in placental pathology and neonatal outcome in singleton vs. twin gestation complicated by small for gestational age. AB - OBJECTIVE: We aimed to compare placental histopathology and neonatal outcome between dichorionic diamniotic (DCDA) twins and singleton pregnancies complicated by small for gestational age (SGA). METHODS: Medical files and placental pathology reports from all deliveries between 2008 and 2017 of SGA neonates, (birthweight < 10th percentile), were reviewed. Comparison was made between singleton pregnancies complicated with SGA (singletons SGA group) and DCDA twin pregnancies (Twins SGA group), in which only one of the neonates was SGA. Placental diameters were compared between the groups. Placental lesions were classified into maternal and fetal vascular malperfusion lesions (MVM and FVM), maternal (MIR) and fetal (FIR) inflammatory responses, and chronic villitis. Neonatal outcome parameters included composite of early neonatal complications. RESULTS: The twins SGA group (n = 66) was characterized by a higher maternal age (p = 0.011), lower gestational age at delivery (34.9 +/- 3.1 vs. 37.7 +/- 2.6 weeks, p < 0.001), and a higher rate of preeclampsia (p = 0.010), compared to the singletons SGA group (n = 500). Adverse composite neonatal outcome was more common in the twins SGA group (p < 0.001). Placental villous lesions related to MVM (p < 0.001) and composite MVM lesions (p = 0.04) were more common in the singletons SGA group. On multivariate logistic regression analysis, the singletons SGA group was independently associated with placental villous lesions (aOR 3.6, 95% CI 1.9-7.0, p < 0.001) and placental MVM lesions (aOR 2.44, 95% CI 1.29-4.61, p = 0.006). CONCLUSION: Placentas from SGA singleton pregnancies have more MVM lesions as compared to placentas from SGA twin pregnancies, suggesting different mechanisms involved in abnormal fetal growth in singleton and twin gestations. PMID- 30284622 TI - [Tobacco prevention using the example of the "smoke-free" campaign : Nationwide measures by the Federal Center for Health Education (BZgA)]. AB - Currently, 28.7% of 18- to 64-year-olds in Germany smoke (26.1% of women/31.2% of men). Among the 12- to 17-year-olds, the smoking rate at 7.4%, is at a historic low. The smoking rate among the 18- to 25-year-olds has also fallen in recent years.The most important goal of the nationwide measures of the Federal Center for Health Education (BZgA) on tobacco prevention is to reduce the smoking rate. For this purpose, the BZgA carries out the "smoke-free" campaign, which is targeted at both adolescents and adults. With a closely interlinked and continuously reviewed and further developed mix of measures, the target groups are reached on the internet, in settings and via media and mass communication. In addition to the information on the risks of smoking and passive smoking, the motivation to quit smoking and the quality-assured support in smoking cessation play an important role here.The measures of the BZgA are reviewed and further developed on the basis of representative surveys on the smoking behavior of the 12- to 25-year-olds, which the BZgA regularly carries out. On this basis, new products, such as e-cigarettes, e-shishas or tobacco heaters, and new consumer trends, such as the trend for waterpipe smoking, are integrated. Access routes to the target groups are continuously reviewed against the background of the digitization of society and the health-promoting design of settings is supported. All in all, the smoke-free campaign offers a quality-assured range of measures that is continuously being developed. PMID- 30284624 TI - ["Heat not burn" tobacco devices as new tobacco industry products: health risks]. AB - Increased tobacco control measures in recent years have directed the tobacco industry to develop alternative tobacco products, such as "heat not burn" (HnB) tobacco devices that are implied to be less hazardous than conventional cigarettes. There are extensive studies from manufacturers available, which show that the emissions of HnB tobacco devices have significantly lower levels of harmful substances compared to conventional cigarettes. In addition, manufacturers have published studies to investigate whether switching from a conventional tobacco cigarette to the HnB product reduces possible health risks.The purpose of this report is to review current studies by manufacturers and independent institutions as well as to discuss possible reduced health hazards.The German Federal Institute for Risk Assessment (BfR) has carried out its own studies of selected analytes in the emissions of one HnB product confirming the lower levels of harmful substances in the emissions. The results are consistent with data from other independent studies. The nicotine content in the emissions is in the same range as the nicotine emissions of conventional cigarettes, which suggests a comparable addictiveness and dependence potential. Manufacturers have reported mutagenic effects of emissions by HnB tobacco devices that, however, are considerably weaker compared to conventional cigarettes. Nevertheless, the use of the HnB tobacco product remains associated with health risks.Switching from conventional cigarettes to tobacco heaters can significantly reduce the consumer's exposure to harmful substances. However, this article also illustrates that it is still unclear to what extent the reduced levels lead to lowered health risks. Therefore more independent studies, but also long-term studies, are needed. PMID- 30284623 TI - [The global medical network Education Against Tobacco-voluntary tobacco prevention made in Germany]. AB - Smoking is the leading preventable cause of premature death in Germany. The network "Education Against Tobacco" (EAT) is an initiative that was founded in Germany in 2012, in which more than 3500 medical students and physicians engage in volunteer work in about 80 medical faculties in 14 countries. In this article, the concept, activities, objectives and associated research studies oft he EAT initiative are introduced.On the school level, the initiative addresses 10- to 15 year-old secondary school students. In addition to a multimodal approach, school visits use modern media such as facemorphing apps, which are not only used by students (45,000 per year in 14 countries), but by a total of over 500,000 other people as well. The effectiveness of the school-based intervention is currently being investigated in randomised long-term studies with 20,000 adolescents in Germany. A first long-term study demonstrated evidence of a protective effect regarding the onset of smoking, especially among female students, students having a low level of education and students with a migratory background.The programme educates several hundred prospective physicians at 13 (of 28 participating) German medical faculties each year in science-based elective courses for the well established smoking cessation counselling of patients and sensitises them to the tobacco epidemic. The approved members engage in dialogue with local members of the German house of representatives as "Arzteverband Tabakpravention".EAT motivates the prospective generation of physicians, initially through prevention in school settings, to face the challenge of national tobacco control at the university and federal level. PMID- 30284625 TI - [E-cigarettes: Perceived harmfulness and use for smoking cessation]. AB - BACKGROUND: The perception that e-cigarettes are less harmful than traditional tobacco products can influence the consumption of e-cigarettes. OBJECTIVES: Three questions were examined: (1) How do different population groups perceive health risks of e-cigarettes? (2) Do sociodemographic variables explain differences in the risk assessment of e-cigarettes? (3) Does the perception of health risks predict the use of e-cigarettes for smoking cessation? METHODS: Data came from the 2015 Epidemiological Survey of Substance Abuse (ESA) with a sample size of n = 9204 participants, aged 18 to 64 years (response rate 52.2%). Data were collected by telephone, online, or by written questionnaires. Assessments of risk perception of e-cigarettes and conventional cigarettes (more harmful, just as harmful, less harmful, do not know) were compared. Descriptive statistics and logistic regressions were performed. RESULTS: Individuals with lower education rated e-cigarettes as more harmful. Older people and women perceived e-cigarettes as just as harmful. Smokers considered e-cigarettes to be more harmful than or just as harmful as conventional tobacco products. The likelihood of using e cigarettes for smoking cessation was higher if people thought they were less harmful than conventional cigarettes. CONCLUSIONS: Only one-third of the population knows that e-cigarettes are less harmful to health than conventional cigarettes. The perception of health risks is related to the usage of e cigarettes for smoking cessation. PMID- 30284626 TI - [E-cigarettes and heat-not-burn products: representative data on consumer behaviour and associated factors in the German population (the DEBRA study)]. AB - BACKGROUND: Electronic cigarettes (ECs) and heat-not-burn (HNB) devices are relatively new products that are increasingly used alternatively or complementary to ordinary tobacco products. OBJECTIVES: To analyse current data from the German Study on Tobacco Use (DEBRA) regarding the prevalence of EC and HNB device use and associated socioeconomic factors and smoking behaviour; compare reasons for EC use between adolescents and adults; describe the self-perceived risk of HNB devices. MATERIAL AND METHODS: DEBRA is an ongoing, representative, face-to-face household survey of the population aged 14 years and older. We analysed data from the first nine waves (June/July 2016 to October/November 2017; n = 18,415) for the current study. RESULTS: During the observation period, 1.9% (95% confidence interval (CI) = 1.7-2.2%) of the German population used ECs (2.8% of the 14- to17 year-olds) and 74.5% (95% CI = 69.4-79.2%) of current EC users also smoked tobacco ("dual use"). Three-quarters of adolescents used ECs mainly "for fun", whereas reasons for use among adults related more to smoking tobacco (e. g., less harmful, to quit smoking). Among current smokers and recent ex-smokers (<12 months smoke-free), 0.3% (95% CI = 0.09-0.64%) currently used HNB devices, and 6.0% (95% CI = 5.0-7.2%) had ever used them. Consumption of HNB products increased with increasing education and income. The majority perceived HNB products as somewhat (41.0%, n = 25) or much (14.8%, n = 9) less harmful, and 37.7% (n = 23) as equally harmful compared with tobacco cigarettes. CONCLUSIONS: In Germany, ECs are mainly consumed as "dual use" together with tobacco. Consumption of HNB products currently occurs at a very low rate and is relatively more common among smokers with higher education and income. It remains important to monitor the use of new electronic inhalation products in the total population and in relevant subgroups. PMID- 30284627 TI - Thailand orthohantavirus infection in patients with chronic kidney disease of unknown aetiology in Sri Lanka. AB - Chronic kidney disease of unknown aetiology (CKDu) reported in Sri Lanka and other countries is a mysterious and serious disease. Recently, we reported a high seroprevalence of antibodies to a hantavirus antigen among CKDu patients in Girandurukotte, Badulla district, Sri Lanka. However, the type of hantavirus with which the residents were infected was not determined. In this study, a total of 89 seropositive sera were examined to identify their serotypes using an indirect immunofluorescent antibody assay, a truncated-N-protein-based enzyme-linked immunosorbent assay, and a cross-neutralization test. These results indicated that the residents in this area were frequently infected with Thailand orthohantavirus or an antigenically related virus. PMID- 30284628 TI - The influence of porcine epidemic diarrhea virus on pig small intestine mucosal epithelial cell function. AB - Porcine epidemic diarrhea (PED) is a highly contagious, acute enteric tract infectious disease of pigs (Sus domesticus) caused by porcine epidemic diarrhea virus (PEDV). PED is characterized by watery diarrhea, dehydration, weight loss, vomiting and death. PEDV damages pig intestinal epithelial tissue, causing intestinal hyperemia and atrophy of intestinal villi, with formation of intestinal epithelial cell cytoplasmic vacuoles. Since pig small intestinal epithelial cells (IECs) are target cells of PEDV infection, IEC cells were utilized as a model for studying changes in cellular activities post-PEDV infection. Monitoring of Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities demonstrated that PEDV infection decreased these activities. In addition, IECs proliferation was shown to decrease after PEDV infection using an MTT assay. Moreover, IECs apoptosis detected by flow cytometry with propidium iodide (PI) staining was clearly shown to increase relative to the control group. Meanwhile, animal experiments indicated that PEDV virulence for IEC cells was greater than viral virulence for Vero cells, although this may be due to viral attenuation after numerous passages in the latter cell line. Collectively, these studies revealed viral pathogenic mechanisms in PEDV-infected IECs and offer a theoretical basis for PEDV prevention and control. PMID- 30284629 TI - Kaposi sarcoma-associated herpes virus (KSHV) latent protein LANA modulates cellular genes associated with epithelial-to-mesenchymal transition. AB - Kaposi's sarcoma-associated herpes virus (KSHV) is a gammaherpesvirus associated with Kaposi's sarcoma and various lymphoproliferative diseases. Epithelial-to mesenchymal transition (EMT) is an important step in the metastasis of cancer cells. Previous studies have shown an important role for EMT markers in B-cell malignancies. In the present study, we investigated the role of the KSHV latent protein LANA in the progression of EMT. Our data suggest that expression of LANA results in an increase in the migration and invasion potential of cancer cells, which is concurrent with modulation of transcriptional regulation and protein expression of several cellular genes associated with EMT. LANA expression results in upregulation of the cellular intermediate filament protein vimentin and transcription factor TCF8/ZEB1 and downregulation of tight junction protein ZO1 and adhesion protein E-cadherin. LANA co-localizes with TCF8/ZEB1, a major contributor in EMT, further suggesting an important role for LANA in epithelial to-mesenchymal transition of KSHV-infected cancer cells.

AB - The present study reports the first complete genome sequence analysis of West Nile virus (WNV) strains isolated from brain samples from raptors. The results prove the circulation of closely related WNV lineage II strains in central Europe and genetic analysis revealed seven amino acid substitutions in structural (PrM3, E159 and E231) and in non-structural (NS1109, NS5259, NS5310 and NS5600) proteins. Observed amino acid substitutions Phe3 and Ser231 were common only within the lineage VII Koutango strain isolated from Rhipicephalus guilhoni tick in Senegal. Further research could reveal whether these substitutions influence the biological properties of WNV, including virulence and neuroinvasiveness. PMID- 30284631 TI - GI.1b/GI.1b/GI.2 recombinant rabbit hemorrhagic disease virus 2 (Lagovirus europaeus/GI.2) in Morocco, Africa. AB - Rabbit hemorrhagic disease virus (RHDV) is highly lethal to the European rabbit (Oryctolagus cuniculus). It was first reported in 1984 in China, but in 2010, a new variant of the virus was detected (GI.2) in France. Several recombination events with pathogenic and non-pathogenic strains have been described. Here, we report the first sequences of RHDV in Africa, isolated from Moroccan rabbits, and these resemble GI.1b/GI.1b/GI.2 recombinants found in the Iberian Peninsula. Monitoring and characterization of strains from future outbreaks are advised to guarantee the success of current programs on small-rabbit production for poverty alleviation in African countries. PMID- 30284632 TI - Isolation, identification, and classification of a novel rhabdovirus from diseased Chinese rice-field eels (Monopterus albus). AB - In 2017, a clinical disease outbreak resulted in substantial mortality of adults and larvae of cultured Chinese rice-field eels (Monopterus albus) on a farm in Hubei, Central China. A rhabdovirus was isolated from moribund specimens, and typical clinical symptoms associated with an outbreak included an enlarged and swollen head. This differed from previous observations. Histological changes included necrosis and cavities of various sizes within the brain and kidney. Homogenized tissues of diseased Chinese rice-field eels were screened for viral isolation using six different fish cell lines. A rhabdovirus was isolated following observation of cytopathic effect (CPE) in a gibel carp brain (GiCB) cell line and confirmed by RT-PCR. Electron microscopy showed large numbers of rhabdovirus-shaped particles in the cytoplasm of the brain cells of the diseased Chinese rice-field eels and in the infected GiCB cell line. This virus has been named "Chinese rice-field eel rhabdovirus" (CrERV), and the complete nucleotide sequence of CrERV was cloned. This rhabdovirus is composed of 11,545 nucleotides with the following genomic organization: 3'-N-P-M-G-L-5'. The genes are separated by conserved gene junctions, and phylogenetic analysis of the L sequence revealed that CrERV forms a separate branch with Siniperca chuatsi rhabdovirus (SCRV) and hybrid snakehead rhabdovirus C1207 (HSHRV-C1207). This is the first report of the complete sequence of CrERV from the Chinese rice-field eel in China. PMID- 30284633 TI - The man from room number seven.

PMID- 30284637 TI - Challenges in assessing the burden of sepsis and understanding the inequalities of sepsis outcomes between National Health Systems: secular trends in sepsis and infection incidence and mortality in Germany. AB - PURPOSE: Sepsis contributes considerably to global morbidity and mortality, while reasons for its increasing incidence remain unclear. We assessed risk adjusted secular trends in sepsis and infection epidemiology in Germany. METHODS: Retrospective cohort study using nationwide German hospital discharge data. We assessed incidence, outcomes and trends of hospital-treated sepsis and infections between 2010 and 2015. Sepsis was identified by explicit ICD-10 sepsis codes. As sensitivity analysis, results were compared with sepsis cases identified by implicit sepsis coding (combined infection and organ dysfunction codes). RESULTS: Among 18 664 877 hospital admissions in 2015, 4 213 116 (22.6%) patients had at least one infection code. There were 320 198 patients that had explicit sepsis codes including 136 542 patients with severe sepsis and septic shock; 183 656 patients were coded as sepsis without organ dysfunction. For patients with explicitly coded sepsis (including severe sepsis), or with severe sepsis alone, mortality rates over the period 2010-2015 decreased from 26.6 to 23.5%, and from 47.8 to 41.7%, respectively. CONCLUSIONS: Sepsis and infection remain significant causes of hospital admission and death in Germany. Sepsis-related mortality is higher and has declined to a lesser degree than in other high-income countries. Although infection rates steadily increased, the observed annual increase of sepsis cases seems to result, to a considerable degree, from improved coding of sepsis.

Analysis of samples from eight representative sites shown that Illumina, optical microscopy, and Roche 454 identified 72, 45 and 19% respective occurrences of all cumulatively present taxa. Optical microscopy failed to detect species of minor occurrence; whereas, amplicon sequencing technologies suffered from failed primer annealing and the presence of species with extensive extracellular polysaccharides production. Amplicon sequencing of the 16S rRNA gene V5-V6 region performed by Illumina identified the cyanobacteria most reliably to the generic level. Nevertheless, only the combined use of optical microscopy, cultivation and sequencing methods allowed for reliable estimate of the cyanobacterial diversity. Here, we show that Rupite hot-spring system hosts one of the richest cyanobacterial flora reported from a single site above 50 degrees C. Chlorogloeopsis sp. was the most abundant at the highest temperature (68 degrees C), followed by Leptolyngbya boryana, Thermoleptolyngbya albertanoae, Synechococcus bigranulatus, Oculatella sp., and Desertifilum sp. thriving above 60 degrees C, while Leptolyngbya geysericola, Geitlerinema splendidum, and Cyanobacterium aponinum were found above 50 degrees C. PMID- 30284642 TI - Low CT temporal sampling rates result in a substantial underestimation of myocardial blood flow measurements. AB - The purpose of this study was to evaluate the effect of temporal sampling rate in dynamic CT myocardial perfusion imaging (CTMPI) on myocardial blood flow (MBF). Dynamic perfusion CT underestimates myocardial blood flow compared to PET and SPECT values. For accurate quantitative analysis of myocardial perfusion with dynamic perfusion CT a stable calibrated HU measurement of MBF is essential. Three porcine hearts were perfused using an ex-vivo Langendorff model. Hemodynamic parameters were monitored. Dynamic CTMPI was performed using third generation dual source CT at 70 kVp and 230-350 mAs/rot in electrocardiography(ECG)-triggered shuttle-mode (sampling rate, 1 acquisition every 2-3 s; z-range, 10.2 cm), ECG-triggered non-shuttle mode (fixed table position) with stationary tube rotation (1 acquisition every 0.5-1 s, 5.8 cm), and non-ECG-triggered continuous mode (1 acquisition every 0.06 s, 5.8 cm). Stenosis was created in the circumflex artery, inducing different fractional flow reserve values. Volume perfusion CT Myocardium software was used to analyze ECG triggered scans. For the non-ECG triggered scans MASS research version was used combined with an in-house Matlab script. MBF (mL/g/min) was calculated for non ischemic segments. True MBF was calculated using input flow and heart weight. Significant differences in MBF between shuttle, non-shuttle and continuous mode were found, with median MBF of 0.87 [interquartile range 0.72-1.00], 1.20 (1.07 1.30) and 1.65 (1.40-1.88), respectively. The median MBF in shuttle mode was 56% lower than the true MBF. In non-shuttle and continuous mode, the underestimation was 41% and 18%. Limited temporal sampling rate in standard dynamic CTMPI techniques contributes to substantial underestimation of true MBF.

AB - Leishmaniasis, a neglected tropical disease caused by protozoans of the genus Leishmania, kills around 20-30 thousand people in Africa, Asia, and Latin America annually and, despite its potential lethality, it can be treated and eventually cured. However, the current treatments are limited owing to severe side effects and resistance development by some Leishmania. These factors make it urgent to develop new leishmanicidal drugs. In the present study, three ruthenium(II) organometallic complexes containing as ligands the commercially available anti inflammatories diclofenac (dic), ibuprofen (ibu), and naproxen (nap) were synthesized, characterized, and subjected to in vitro leishmanicidal activity. The in vitro cytotoxicity assays against Leishmania (L.) amazonensis and Leishmania (L.) infantum promastigotes have shown that complexes [RuCl(dic)(eta6 p-cymene)] (1) and [RuCl(nap)(eta6-p-cymene)] (3) were active against both Leishmania species. Complex [RuCl(ibu)(eta6-p-cymene)] (2) has exhibited no activity. The IC50 values for the two active complexes were respectively 7.42 and 23.55 MUM, for L. (L.) amazonensis, and 8.57 and 42.25 MUM, for L. (L.) infantum. Based on the toxicological results and computational analysis, we proposed a correlation between the complexes and their activity. Our results suggest both complexation to ruthenium(II) and ligands structure are key elements to leishmanicidal activity. PMID- 30284644 TI - Chromosomal Sil system contributes to silver resistance in E. coli ATCC 8739. AB - The rise of antibiotic resistance in pathogenic bacteria is endangering the efficacy of antibiotics, which consequently results in greater use of silver as a biocide. Chromosomal mapping of the Cus system or plasmid encoded Sil system and their relationship with silver resistance was studied for several gram-negative bacteria. However, only few reports investigated silver detoxification mediated by the Sil system integrated in Escherichia coli chromosome. Accordingly, this work aimed to study the Sil system in E. coli ATCC 8739 and to produce evidence for its role in silver resistance development. Silver resistance was induced in E. coli ATCC 8739 by stepwise passage in culture media containing increasing concentrations of AgNO3. The published genome of E. coli ATCC 8739 contains a region showing strong homology to the Sil system genes. The role of this region in E. coli ATCC 8739 was assessed by monitoring the expression of silC upon silver stress, which resulted in a 350-fold increased expression. De novo sequencing of the whole genome of a silver resistant strain derived from E. coli ATCC 8739 revealed mutations in ORFs putative for SilR and CusR. The silver resistant strain (E. coli AgNO3R) showed constitutive expression of silC which posed a cost of fitness resulting in retarded growth. Furthermore, E. coli AgNO3R exhibited cross-resistance to ciprofloxacin and a slightly increased tolerance to ampicillin. This study demonstrates that E. coli is able to develop resistance to silver, which may pose a threat towards an effective use of silver compounds as antiseptics. PMID- 30284646 TI - Imbalance of circulating Tfr/Tfh ratio in patients with rheumatoid arthritis. AB - Follicular helper T(Tfh) cells and follicular regulatory T(Tfr) cells are critical for the development and maintenance of germinal center and humoral immune responses. Accumulating evidence has demonstrated that the dysregulation of either Tfh or Tfr cells contributes to the pathogenesis of autoimmune diseases. The aim of this study was to examine the numbers of Tfh and Tfr cells in patients with rheumatoid arthritis (RA). Twenty-four patients with RA patients and 20 health controls (HCs) were enrolled in this study. We analyzed the numbers of Tfh (CD4+ CXCR5+ PD-1hi) cells and Tfr (CD4+ CXCR5+CD127lo) cells in 24 RA patients via flow cytometry. The level of the soluble PD-1 and its ligands (sPD L1 and sPDL-2) were examined by ELISA. Flow cytometry revealed that both circulating Tfh and Tfr cells were increased in RA patients compared with HCs. More importantly, the ratio of Tfr/Tfh was decreased, indicating a disruption of the balance between Tfh and Tfr. The Tfr/Tfh ratio was inversely correlated with level of serum CRP, ESR, RF, anti-CCP, IgG and DAS28 index. We also found that the serum level of sPD-1 was significantly elevated in the RA patients, which was positively correlated with CRP, ESR and the number of Tfh cells. These results indicate that an imbalance of circulating Tfr and Tfh cells may be involved in the immunopathogenesis of RA and may provide novel insight for the development of RA therapies. PMID- 30284645 TI - App-Based Insulin Calculators: Current and Future State. AB - PURPOSE OF REVIEW: To perform a comprehensive literature review and critical assessment of peer-reviewed manuscripts addressing the efficacy, safety, or usability of insulin calculator apps. RECENT FINDINGS: Managing diabetes with insulin can be complex, and literacy and numeracy skills pose barriers to manual insulin dose calculations. App-based insulin calculators are promising tools to help people with diabetes administer insulin safely and have potential to improve glycemic control. While a large number of apps which assist with insulin dosing are available, there is limited data evaluating their efficacy, safety, and usability. Recently, a need for regulatory oversight has been recognized, but few apps meet federal standards. Thus, choosing an appropriate app is challenging for both patients and providers. An electronic literature review was performed to identify insulin calculator apps with either evidence for efficacy, safety or usability published in peer-reviewed literature or with FDA/CE approval. Twenty apps were identified intended for use by patients with diabetes on insulin. Of these, nine included insulin calculators. Summaries of each app, including pros and cons, are provided. Insulin-calculator apps have the potential to improve self-management of diabetes. While current literature demonstrates improvements in quality of life and glycemic control after use of these programs, larger trials are needed to collect outcome and safety data. Also, further human factor analysis is needed to assure these apps will be adopted appropriately by people with diabetes. App features including efficacy and safety data need to be easily available for consumer review and decision making. Higher standards need to be set for app developers to ensure safety and efficacy. PMID- 30284647 TI - Volumetric modulated arc therapy (VMAT) in the treatment of esophageal cancer patients. AB - The aim of the study is to evaluate feasibility, safety, toxicity profile, and dosimetric results of volumetric modulated arc therapy (VMAT) to deliver definitive or pre-operative radiation in locally advanced esophageal cancer patients. A total of 68 patients were treated with VMAT between March 2014 and March 2018 (44% vs 56% for definitive and neoadjuvant settings, respectively). Dose prescription differed depending on the clinical scenario (54-60 Gy in 30 fractions for definitive treatments; 41.4/45 Gy in 23-25 fractions in the pre operative setting). Most of the patients were given concurrent chemotherapy. Two coplanar and one non-coplanar arcs were employed for VMAT delivery. Treatment was generally well tolerated. Acute toxicity was generally mild. In patients treated with definitive intent, >= G3 toxicities were observed for esophagitis (30%), anorexia (26.7%), fatigue (26.7%), nausea (6.7%), and vomiting (3.3%). In patients treated within a neoadjuvant approach, >= G3 anorexia (21%), esophagitis (15.8%), fatigue (13.3%), nausea (5.3%), and vomiting (2.6%) were observed. Dosimetric results were consistent in term of both target coverage and normal tissue sparing. In conclusion, VMAT proved to be a feasible, safe, and effective strategy to deliver definitive or pre-operative radiation in locally advanced esophageal cancer patients. PMID- 30284649 TI - The use of radiofrequency ablation in pancreatic cancer in the midst of the dawn of immuno-oncology. AB - Despite significant improvement in treatment, the prognosis of pancreatic ductal adenocarcinoma remains poor as the biology of the tumour affects survival even when a radical resection has been performed. Pancreatic cancer remains resistant to currently available chemotherapeutic options. Recently, immunotherapy has achieved significant results in certain types of cancer. However, for pancreatic cancer, results were not initially encouraging as pancreatic cancer microenvironment is highly immunosuppressive. Radiofrequency ablation is currently used as treatment option especially for liver cancer with significant results. However, in pancreatic cancer, the use of radiofrequency ablation is relatively new. Radiofrequency ablation has been identified as a promising mechanism to induce antigen-presenting cell infiltration and enhance systemic antitumour T-cell immune response and tumour regression. In this short communication, we briefly review the role of radiofrequency ablation in pancreatic cancer and explore the idea that the combination of radiofrequency ablation with immunotherapy could represent a novel and promising treatment. PMID- 30284650 TI - Perspectives on the role of brain cellular players in cancer-associated brain metastasis: translational approach to understand molecular mechanism of tumor progression. AB - Brain metastasis is one of the leading causes of death among cancer patients. Cancer cells migrate to various sites and harbor different niche in the body which help cancer cells in their survival. The brain is one of the safest place where cancer cells are protected from immune cells. Breast, lung, and melanoma cancer cells have high propensity to migrate towards the brain. To enter the brain, cancer cells have to cross the blood brain barrier. Survival and finding new niche in the brain are directed by several mechanisms in which different cellular players take part such as astrocytes, microglia, Schwann cells, satellite cells, oligodendrocytes, and ependymal cells. Usually, cancer cells highjack the machinery of brain cellular players to survive in the brain environment. It has been shown that co-culture of M2 macrophage with cancer cells leads to increased proliferation and survival of cancer cells. One of the challenges of understanding brain metastasis is appropriate model system to understand dynamic interaction of cancer cells and brain cellular players. To meet this challenge, microfluidic-based devices are employed which can mimic the dynamic conditions as well as can be used for culturing human cells for personalized therapy. In this review, we have systematically reviewed the current status of the role of cellular players in brain metastasis along with explaining how translational approach of microfluidics can be employed for finding new drug target as well as biomarker for brain metastasis. Finally, we have also commented on the mechanism of action of drugs against brain metastasis. PMID- 30284648 TI - Biotechnological potential of plant growth-promoting bacteria from the roots and rhizospheres of endemic plants in ironstone vegetation in southeastern Brazil. AB - Microorganisms associated with plants have a great biotechnological potential, but investigations of these microorganisms associated with native plants in peculiar environments has been incipient. The objective of this study was to analyze the plant growth-promoting bacteria potential of cultivable bacteria associated with rare plants from the ferruginous rocky fields of the Brazilian Iron Quadrangle. The roots and rhizospheres of nine endemic plants species and samples of a root found in a lateritiric duricrust (canga) cave were collected, the culturable bacteria isolated and prospected for distinct biotechnological and ecological potentials. Out of the 148 isolates obtained, 8 (5.4%) showed potential to promote plant growth, whereas 4 (2.7%) isolates acted as biocontrol agents against Xanthomonas citri pathotype A (Xac306), reducing the cancrotic lesions by more than 60% when co-inoculated with this phytopathogen in Citrus sinensis plants. Moreover, other 4 (2.7%) isolates were classified as potential bioremediation agents, being able to withstand high concentrations of arsenite (5 mM As3+) and arsenate (800 mM As5+), by removing up to 35% and 15% of this metalloid in solution, respectively. These same four isolates had a positive influence on the growth of both the roots and the aerial parts when inoculated with tomato seeds in the soil contaminated with arsenic. This is the first time that an investigation highlights the potentialities of bacteria associated with rare plants of ferruginous rocky fields as a reservoir of microbiota of biotechnological and ecological interest, highlighting the importance of conservation of this area that is undergoing intense anthropic activity. PMID- 30284651 TI - Dual Red Imaging Maintains Clear Visibility During Colorectal Endoscopic Submucosal Dissection. AB - BACKGROUND: The endoscopic lens becomes clouded and its visibility reduces during colorectal endoscopic submucosal dissection (ESD), especially in cases with submucosal fatty tissue. Dual red imaging (DRI) is a novel image-enhanced endoscopic technique that improves endoscopic visibility. AIMS: This study aimed to evaluate the predictive factors of submucosal fatty tissue and the clinical usefulness of DRI in maintaining clear visibility during colorectal ESD. METHODS: The study participants included 586 consecutive patients with 645 colorectal tumors who underwent ESD between January 2014 and July 2017. First, the degree of submucosal fatty tissue was evaluated by reviewing recorded images, and the clinical characteristics of the patients and tumors related to severe submucosal fatty tissue were evaluated. Second, 34 tumors resected using DRI were propensity score-matched in a 1:1 ratio to other resected tumors using white light imaging (WLI), and the degree of endoscope lens cloudiness and clinical outcomes were evaluated. RESULTS: The proportion of tumors located in the right side of the colon, body mass index (>= 25, BMI), and hemoglobin A1c (>= 6.5%, HbA1c) were significantly higher in patients with severe submucosal fatty tissue. The visibility in the DRI group was significantly better than in the WLI group. Treatment outcomes in the DRI group were as good as those in the WLI group. CONCLUSIONS: Tumor location in the right side of the colon, BMI (>= 25), and HbA1c (>= 6.5%) are the predictive factors of severe submucosal fatty tissue. DRI is useful in maintaining clear visibility during colorectal ESD, especially with submucosal fatty tissue. PMID- 30284652 TI - High Trophinin-Associated Protein Expression Is an Independent Predictor of Poor Survival in Liver Cancer. AB - BACKGROUND: Trophinin-associated protein (TROAP) is a cytoplasmic protein that functions as an adhesion molecule in processes such as embryo implantation, spindle formation, and cancer. OBJECTIVE: To evaluate the relationship of TROAP expression in hepatocellular carcinoma (HCC) tissue with clinicopathologic parameters and survival time in liver cancer patients based on an analysis of The Cancer Genome Atlas Liver Hepatocellular Carcinoma (TCGA-LIHC) data. METHODS: RNA sequencing (RNA-Seq) expression data and clinical information were downloaded for the TCGA-LIHC cohort. Associations between TROAP expression in HCC tissues and clinical parameters were evaluated by Chi-square tests. Differences in survival between high and low expression groups (median expression cutoff) from Cox regression analysis were compared, and P values were calculated by a log-rank test. Kaplan-Meier curves were compared with the log-rank test. RESULTS: Analysis of RNA-Seq gene expression data for 373 patients with primary tumors revealed overexpression of TROAP in liver cancer. High TROAP expression was associated with survival status (P = 0.015), T stage (P = 0.049), clinical stage (P = 0.048), and gender (P = 0.033). Patients with high TROAP-expressing liver cancers had a shorter median overall survival of 3.83 years compared with 5.80 years for patients with low TROAP-expressing liver cancers (P = 0.00422). Multivariate analysis identified TROAP expression as an independent prognostic variable for overall survival in liver cancer patients. CONCLUSION: TROAP expression is an independent predictor of poor survival in liver cancer. PMID- 30284654 TI - Antifungal efficacy of photodynamic therapy with TONS 504 for pathogenic filamentous fungi. AB - The pathogenic filamentous fungi Fusarium solani (F. solani) and Aspergillus fumigatus (A. fumigatus) are common causes of fungal keratitis. We have here evaluated the antifungal efficacy of photodynamic antimicrobial chemotherapy (PACT) with the novel chlorin derivative TONS 504 and a light-emitting diode (LED) with a wavelength of 660 nm for these fungal species. Isolated fungal spores were irradiated at LED energies of 10, 20, or 30 J/cm2 in the presence of TONS 504 at concentrations of 1 or 10 mg/L. As a control, spores were exposed to TONS 504 or LED radiation alone. The treated spores were then cultured on potato dextrose agar plates at 25 degrees C for 3 to 4 days before determination of colony formation as a measure of viability. Fungal growth was inhibited in a manner dependent on both LED energy and TONS 504 concentration. The inhibitory effect on F. solani was complete with TONS 504 at a concentration of 1 mg/L and LED irradiation at 30 J/cm2 as well as at a TONS 504 concentration of 10 mg/L and LED irradiation at 10, 20, or 30 J/cm2. In contrast, that on A. fumigatus was only partial at a TONS 504 concentration of 10 mg/L and LED irradiation at 20 or 30 J/cm2. The antifungal effect of PACT on A. fumigatus was thus inferior to that on F. solani. PACT with TONS 504 and an LED thus warrants further evaluation with regard to its potential effectiveness for the treatment of infectious fungal keratitis. PMID- 30284653 TI - High Adherence to HIV Pre-exposure Prophylaxis and No HIV Seroconversions Despite High Levels of Risk Behaviour and STIs: The Australian Demonstration Study PrELUDE. AB - PrELUDE study evaluated daily pre-exposure prophylaxis (PrEP) in high-risk individuals in Australia. This open-label, single-arm study tested participants for HIV/STI and collected behavioural information three-monthly. We report trends over 18 months in medication adherence, side-effects, HIV/STI incidence and behaviour. 320 gay/bisexual men (GBM), 4 women and 3 transgender participants, followed on average 461 days, reported taking seven pills/week on 1,591 (88.5%) occasions and 4-6 pills/week on 153 (8.5%) occasions. No HIV infections were observed. STI incidence was high and stable, while gonorrhoea infections declined from 100.0 to 25.8/100 person-years between 6 and 15 months (p < 0.001). The number of HIV-positive and unknown-status sex partners, and condomless anal intercourse, significantly increased. In this high-risk cohort of mainly GBM, increases in risk behaviours and high STI incidence were not accompanied by HIV infections due to high adherence to daily PrEP. The study informed policy and further PrEP implementation among Australian GBM. PMID- 30284655 TI - Auditory brainstem response to speech in children with high functional autism spectrum disorder. AB - Auditory brainstem response (ABR) provides useful information about the auditory brainstem pathway. However, there is little known about the subcortical speech processing in individuals with autism spectrum disorder (ASD). The aim of the present study was to investigate the subcortical speech processing in children with high functioning ASD. Twenty-eight children with ASD, with a mean age of 14.36 +/- 1.86, and 28 typically developing (TD) children, with a mean age of 14.99 +/- 1.92, were selected from Rofeydeh Rehabilitation Hospital (Tehran, Iran), and speech ABR (sABR) with a 40 ms synthetic /da/ syllable stimulus was recorded. There was no significant difference between the two groups in terms of age and IQ. Latencies of all waves in sABR and duration of V-A complex were significantly longer in children with ASD than in TD children. It was concluded that patients with ASD have deficits in the temporal neural encoding of speech at the brainstem level. Further studies are needed to generalize this result.

PMID- 30284658 TI - On the Force-Feeding of Prisoners on Hunger Strike. AB - Roughly 80,000 U.S. prisoners are held in solitary confinement at any given time. A significant body of research shows that solitary confinement has severe, long term effects, and the United Nations has condemned the practice of solitary confinement as torture. For years, prisoners have been organizing hunger strikes in order to protest solitary confinement. But such action is not without consequences, and some inmates have suffered serious injury or death. The question I raise in this paper is whether we ought to force-feed hunger striking prisoners when serious harm is imminent. Both the World Medical Association and the American Medical Association have denounced the practice of force-feeding prisoners on hunger strike, and yet, the practice is common. Such prevalence is likely a result of the tension between the person-as-patient and person-as prisoner and cannot easily be resolved. Instead, we must take seriously the complaint that solitary confinement is inhumane and avoid placing health professionals in the position where they must choose to force-feed the prisoner against his will or not. I argue that a conventional bioethics debate centering on polarizing principles of prisoner autonomy and a duty-to-protect the prisoner from harm is an inadequate framework for this complex issue. Instead, we must examine the prisoner's intent and his right to freedom of speech. I argue that when the prisoner's intent is to raise awareness and communicate with others, his hunger strike is a form of speech. Protest-as-speech is constitutionally protected-even for prisoners-and remains a minimum ethical obligation for society to uphold. PMID- 30284659 TI - HKUST-1 metal-organic framework for dispersive solid phase extraction of 2-methyl 4-chlorophenoxyacetic acid (MCPA) prior to its determination by ion mobility spectrometry. AB - The authors describe a method for the extraction of the herbicide 2-methyl-4 chlorophenoxyacetic acid (MCPA) from agricultural products. The metal organic framework (MOF) HKUST-1 (a copper(II) benzene-1,3,5-tricarboxylate) was used as a sorbent for efficient clean-up and preconcentration of MCPA. The effects of pH value, stirring time, amount of sorbent on extraction were optimized by central composite design. Ultrasonic waves were used for desorption procedure and its advantage was demonstrated for an increase in extraction recovery. Corona discharge ion mobility spectrometry (IMS) was then applied for fast and sensitive determination of MCPA. The method was validated in terms of sensitivity, recovery and reproducibility. Under the optimum conditions the calibration plot is linear between 0.035-0.200 MUg. L-1. The detection limit is 10 ng L-1, with relative standard deviations of <5%. Real samples (water, soil and agricultural product) were spiked and then analyzed by this method, and the results revealed efficient solid phase extraction and recovery. Graphical abstract Schematic presentation of a procedure for extraction of an organochlorine pesticide (2-methyl-4 chlorophenoxyacetic acid) from agriculture products using the HKUST-1 metal organic framework prior to determination by ion mobility spectrometry based on its ionization in drift cell. PMID- 30284660 TI - Ovarian small cell carcinoma in one of a pair of monozygous twins. AB - One of a pair of monozygous twins was diagnosed and died of small cell carcinoma of the ovary of hypercalcemic type (SCCOHT) at the age of 30 years. Her sister remained unaffected and was very concerned about her risk for developing SCCOHT. By performing comprehensive molecular analysis using whole exome sequencing (WES) approach, we showed that the deceased twin's tumour has bi-allelic somatic genetic defects (a pathogenic frameshift deletion in SMARCA4 and LOH on chr19p). Results of WES of constitutional DNA from her unaffected sister were confirmatory. Based on our findings, we concluded that the living twin is not at risk for SCCOHT and does not need to consider preventive oophorectomy. PMID- 30284661 TI - Implantable devices to monitor patients with heart failure. AB - Reducing heart failure hospitalizations represents a major challenge for modern clinicians. Early detection of congestion plays a key role in disease management strategy. Apart from traditional methods (patient reporting symptoms, body weight monitoring), novel home-care strategies allow guided adjustments in medical therapy through telemonitoring embedded in cardiac electronic implantable devices or through stand-alone diagnostic devices for hemodynamic monitoring. Wireless pulmonary artery pressure monitoring seems to reduce re-admission risk and is currently approved for this purpose in patients with heart failure. Multiparameter monitoring is also appealing and could be a valuable tool in managing these patients. However, invasive techniques face several safety concerns and cost-effectiveness issues. Therefore, quest for future research and emerging technologies is necessary. PMID- 30284662 TI - Separation of glycosphingolipids with titanium dioxide. AB - We introduce the principle of a new technique to isolate glycosphingolipids (GSLs) from phospholipids. Neutral and acidic GSLs in organic solvent bind to titanium dioxide under neutral pH and can be eluted with 5 mg/ml of 2,5 dihydroxybenzoic acid in methanol. This special property is applicable for eliminating phospholipids, including sphingomyelin, which cannot be eliminated by a typical mild alkaline treatment. By using this technique, we demonstrated the rapid separation of minor components of GSLs, namely sulfatide and gangliosides from rabbit serum and liver, respectively. The minor GSL components were effectively purified despite both sources containing tremendous amount of phospholipids and simple lipids such as cholesterol, cholesteryl esters and triglycerides. PMID- 30284663 TI - Neurofeedback Improves Memory and Peak Alpha Frequency in Individuals with Mild Cognitive Impairment. AB - Mild cognitive impairment (MCI) is a syndrome characterized by a decrease in cognitive abilities, while daily function is maintained. This condition, which is associated with an increased risk for the development of Alzheimer's disease, has no known definitive treatment at present. In this open-label pilot study we explored the possible benefits of neurofeedback for subjects with MCI. Eleven participants diagnosed with MCI were trained to increase the power of their individual upper alpha band of the electroencephalogram (EEG) signal over the central parietal region. This was achieved using an EEG-based neurofeedback training protocol. Training comprised ten 30-min sessions delivered over 5 weeks. Cognitive and electroencephalographic assessments were conducted before and after training and at 30 days following the last training session. A dose-dependent increase in peak alpha frequency was observed throughout the period of training. Memory performance also improved significantly following training, and this improvement was maintained at 30-day follow-up, while peak alpha frequency returned to baseline at this evaluation. Our findings suggest that neurofeedback may improve memory performance in subjects with mild cognitive impairment, and this benefit may be maintained beyond the training period. PMID- 30284664 TI - Dust distribution in open-pit mines based on monitoring data and fluent simulation. AB - To understand the concentration and distribution of PM2.5 and PM10 in open-pit mines, a beta-ray particle monitor and some laser monitors were arranged in Haerwusu Surface Coal Mine (HSCM), Inner Mongolia, China. A fluent simulation was made to study the dust move in the pit and escape rate and time out of the pit. The main conclusions include (1) in HSCM, the concentration of PM10 changes with that of PM2.5, meeting the power function PM10 = 2.548 * PM2.50.993. The dust concentration around the working mining equipment is very high. For example, around a working drill, the PM2.5 can be up to 426 MUg/m3, and around a working power shovel, the PM2.5 can be up to 352 MUg/m3. (2) At the same time, the PM2.5 concentration is nearly equal throughout the pit, away from the operating equipment, with a confidence level of 95%. The mean dust concentration away from the equipment is 76.7 MUg/m3 when this mining equipment is working. So, the number of monitors in the pit can be decreased without affecting the quality of dust monitoring, which means that the cost of monitoring can be cut down. (3) Base on Fluent simulation results, the average escape time of dust particles with different diameters is similar, but the maximum escape time decreases as the particle diameter increases, which means that most dust moves with the air swirl, but some smaller dust particles can hang in the pit for a longer time. Also, the escape rate decreases rapidly as the diameter of the dust increases. (4) Dust is rotated and diffused evenly in the pit under the action of the eddy current in the pit. Finally, when the dust is swirled to a higher level than that of the pit head, the dust can escape out of the pit. PMID- 30284666 TI - College Students' Evaluations and Reasoning About Exclusion of Students with Autism and Learning Disability: Context and Goals may Matter More than Contact. AB - This study used mixed-effects logistic regression to examine undergraduates' (N = 142) evaluations and reasoning about scenarios involving disability-based exclusion. Scenarios varied by disability [autism spectrum disorder (ASD) versus learning disability (LD)], the context of exclusion (classroom versus social), and whether or not a grade was at stake. Participants were more likely to determine exclusion was acceptable if the excluded student had an ASD diagnosis, there was a grade at stake, and it occurred in a classroom. Exclusion was less likely to be considered acceptable in the "no grade" compared to the "grade" conditions for LD students, but remained high in both conditions for autistic students. This study also describes contextual variations in participants' justifications for their evaluations. PMID- 30284667 TI - Diagnostic and Therapeutic Misconception: Parental Expectations and Perspectives Regarding Genetic Testing for Developmental Disorders. AB - Parents' understanding/expectations regarding genetic testing for children with developmental disorders were explored. Within a month of testing, interviews were conducted with 57 parents. Many (74%) could not recall the nature of testing. Parents expected genetic testing to have positive impacts for the child (93%) and the family (98%), mainly to find the etiology and/or an intervention. Many parents (40%) reported not knowing their child's clinical diagnosis. They expected genetic testing would establish the diagnosis. Parents anticipated potential negative impacts of testing for children (78%) and families (87%), mainly finding another illness or not finding potential interventions. Abnormal results explaining the disorder were found in 9% of children. In summary, genetic results for developmental disorders are unlikely to meet parental expectations. PMID- 30284668 TI - 1H, 15N, and 13C resonance assignments of the intrinsically disordered SH4 and Unique domains of Hck. AB - Hematopoietic cell kinase (Hck) is an important signaling enzyme and a potential drug target for HIV infections and Bcr/Abl-chronic myeloid leukemia. The protein shares the same SH4-Unique-SH3-SH2-kinase multi-domain architecture as the other eight members of the Src family of non-receptor tyrosine kinases. These enzymes are often found anchored to the intracellular side of the membrane via lipidation of the SH4 domain and are integral components of signaling cascades localized at the cell surface. Despite the detailed structural information available for the SH3, SH2, and kinase domains of Hck, the intrinsically disordered nature of the SH4 and Unique domains has resulted in a lack of information for this important region of the protein that is responsible for membrane association. Here, we report the 1H, 15N and 13C chemical shifts of the Hck SH4-Unique domains at pH 4.5.

AB - Antibiotic resistance is increasing among Staphylococcus saprophyticus strains isolated from urinary tract infection. This necessitates alternative therapies. For this, a lytic phage (vB_SsapS-104) against S. saprophyticus, which formed round and clear plaques on bacterial culture plates, was isolated from hospital wastewater and characterized. Microscopy analysis showed that it had a small head (about 50 nm), tail (about 80 nm), and a collar (about 22 nm in length and 19 nm in width) indicating to be a phage within Siphoviridae family. Phage vB_SsapS-104 showed a large latency period of about 40 min, rapid adsorption rate that was significantly enhanced by MgCl2 and CaCl2, and high stability to a wide range of temperatures and pH values. Restriction analyses demonstrated that phage consists of a double-stranded DNA with an approximate genome size of 40 Kb. BLAST results did not show high similarity (megablast) with other previously identified phages. But, in Blastn, similarity with Staphylococcus phages was observed. Phage vB_SsapS-104 represented high anti-bacterial activity against S. saprophyticus isolates in vitro as it was able to lyse 8 of the 9 clinical isolates (%88.8) obtained from a hospital in Gorgan, Iran. It was a S. saprophyticus-specific phage because no lytic activity was observed on some other pathogenic bacteria tested. Therefore, phage vB_SsapS-104 can be considered as a specific virulent phage against of S. saprophyitcus isolated from urinary tract infection. This study provided the partial genomic characterization of S. saprophyticus phage and its application against urinary tract infection associated with S. saprophyticus. This phage also can be considered as a good candidate for a therapeutic alternative in the future.

AB - PURPOSE OF REVIEW: Parkinson's disease (PD) is the second most common neurodegenerative disorder affecting older individuals. The specific cause underlying dopaminergic (DA) neuron loss in the substantia nigra, a pathological hallmark of PD, remains elusive. Here, we highlight peer-reviewed reports using induced pluripotent stem cells (iPSCs) to model PD in vitro and discuss the potential disease-relevant phenotypes that may lead to a better understanding of PD etiology. Benefits of iPSCs are that they retain the genetic background of the donor individual and can be differentiated into specialized neurons to facilitate disease modeling. RECENT FINDINGS: Mitochondrial dysfunction, oxidative stress, ER stress, and alpha-synuclein accumulation are common phenotypes observed in PD iPSC-derived neurons. New culturing technologies, such as directed reprogramming and midbrain organoids, offer innovative ways of investigating intraneuronal mechanisms of PD pathology. PD patient-derived iPSCs are an evolving resource to understand PD pathology and identify therapeutic targets. PMID- 30284671 TI - Standardization of Autoantibody Testing in Autoimmune Hepatitis.

PMID- 30284672 TI - Fused Group Lasso Regularized Multi-Task Feature Learning and Its Application to the Cognitive Performance Prediction of Alzheimer's Disease. AB - Alzheimer's disease (AD) is characterized by gradual neurodegeneration and loss of brain function, especially for memory during early stages. Regression analysis has been widely applied to AD research to relate clinical and biomarker data such as predicting cognitive outcomes from MRI measures. Recently, multi-task based feature learning (MTFL) methods with sparsity-inducing [Formula: see text]-norm have been widely studied to select a discriminative feature subset from MRI features by incorporating inherent correlations among multiple clinical cognitive measures. However, existing MTFL assumes the correlation among all tasks is uniform, and the task relatedness is modeled by encouraging a common subset of features via sparsity-inducing regularizations that neglect the inherent structure of tasks and MRI features. To address this issue, we proposed a fused group lasso regularization to model the underlying structures, involving 1) a graph structure within tasks and 2) a group structure among the image features. To this end, we present a multi-task feature learning framework with a mixed norm of fused group lasso and [Formula: see text]-norm to model these more flexible structures. For optimization, we employed the alternating direction method of multipliers (ADMM) to efficiently solve the proposed non-smooth formulation. We evaluated the performance of the proposed method using the Alzheimer's Disease Neuroimaging Initiative (ADNI) datasets. The experimental results demonstrate that incorporating the two prior structures with fused group lasso norm into the multi-task feature learning can improve prediction performance over several competing methods, with estimated correlations of cognitive functions and identification of cognition-relevant imaging markers that are clinically and biologically meaningful. PMID- 30284670 TI - Acceptability of two- versus three-dose human papillomavirus vaccination schedule among providers and mothers of adolescent girls: a mixed-methods study in five countries. AB - PURPOSE: The World Health Organization revised its human papillomavirus (HPV) vaccination recommendations to include a two (2-) dose schedule for girls aged <= 15 years. We investigated acceptability of 2- versus 3-dose schedule among adolescent vaccination providers and mothers of adolescent girls in five countries. METHODS: Adolescent vaccination providers (N = 151) and mothers of adolescent girls aged 9-14 years (N = 118) were recruited from Argentina, Malaysia, South Africa, South Korea, and Spain. We assessed providers' preference for a 2- versus 3-dose HPV vaccination schedule via quantitative surveys. Mothers' attitudes towards a 2-dose schedule were assessed through focus group discussions. RESULTS: Most adolescent providers preferred a 2- over a 3-dose HPV vaccination schedule (overall: 74%), with preference ranging from 45.2% (South Africa) to 90.0% (South Korea). Lower cost, fewer clinic visits, and higher series completion were commonly cited reasons for 2-dose preference among providers and mothers. Safety and efficacy concerns were commonly cited barriers to accepting a 2-dose HPV vaccination schedule among providers and mothers. Mothers generally accepted the reduced schedule, however requested further information from a trusted source. CONCLUSIONS: Adolescent vaccination providers and mothers preferred the 2-dose over 3-dose HPV vaccination schedule. Acceptability of a 2-dose HPV vaccination could be improved with additional information to providers and mothers on HPV vaccination safety and efficacy. PMID- 30284673 TI - The 1980s: D-AP5, LTP and a Decade of NMDA Receptor Discoveries. AB - In the 1960s and 70s, biochemical and pharmacological evidence was pointing toward glutamate as a synaptic transmitter at a number of distinct receptor classes, known as NMDA and non-NMDA receptors. The field, however, lacked a potent and highly selective antagonist to block these putative postsynaptic receptors. So, the discoveries in the early 1980s of D-AP5 as a selective NMDA receptor antagonist and of its ability to block synaptic events and plasticity were a major breakthrough leading to an explosion of knowledge about this receptor subtype. During the next 10 years, the role of NMDA receptors was established in synaptic transmission, long-term potentiation, learning and memory, epilepsy, pain, among others. Hints at pharmacological heterogeneity among NMDA receptors were followed by the cloning of separate subunits. The purpose of this review is to recognize the important contributions made in the 1980s by Graham L. Collingridge and other key scientists to the advances in our understanding of the functions of NMDA receptors throughout the central nervous system. PMID- 30284674 TI - A Novel Ileocolonic Release Peppermint Oil Capsule for Treatment of Irritable Bowel Syndrome: A Phase I Study in Healthy Volunteers. AB - INTRODUCTION: Peppermint oil (PO) has been shown to reduce abdominal pain in patients with irritable bowel syndrome (IBS). PO is assumed to induce intestinal smooth muscle relaxation and desensitization of nociceptive nerve afferents. To increase colonic PO concentration, an ileocolonic release peppermint oil (IC-PO) capsule has been developed. The aim of this study was to compare pharmacokinetic parameters of the currently available small intestinal release PO (SI-PO) and the novel IC-PO. METHODS: In this randomized, double-blind, crossover study, subjects received 182 mg of either SI-PO or IC-PO in a crossover design with a washout period of more than 14 days. Blood samples were collected to determine menthol glucuronide concentrations. RESULTS: Eight healthy volunteers (50% female, median age 22) were included. The time to reach the maximum concentration (Tmax) of IC PO was significantly longer compared to SI-PO with a median (IQR) of 360 (360 405) versus 180 (120-180) min. The lag time (Tlag) was significantly longer with a median (IQR) of 225 (204-284) for IC-PO compared to 37 (6-65) min for SI-PO. The areas under the menthol glucuronide plasma concentration-time curves were significantly smaller with a median (IQR) of 2331 MUg h/L (2006-2510) for IC-PO compared to 2623 MUg h/L (2471-2920) for SI-PO. No significant differences were found in peak concentrations and elimination half-lives. CONCLUSION: IC-PO has a significantly delayed peak menthol glucuronide concentration and Tlag, both pointing to the release of PO in the more distal part of the intestine. This may enhance therapeutic efficacy as it results in increased exposure of colonic mucosal afferents to the PO. A randomized controlled trial investigating the efficacy of SI and IC-PO in IBS is currently ongoing. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT02291445, EudraCT database 2014-004195-32. PMID- 30284675 TI - Ethanol via Regulation of NF-kappaB/p53 Signaling Pathway Increases Manganese Induced Inflammation and Apoptosis in Hypothalamus of Rats. AB - The diet is a major route of manganese (Mn) exposure for humans. Interestingly, several epidemiological data demonstrated an increase in the incidence of alcohol consumption globally. Chemical-chemical interaction subsequent to chemical mixtures exposure may result in a synergism or antagonism effects. The present study investigated the influence of co-exposure to ethanol (EtOH) and Mn on inflammation and apoptosis in the hypothalamus of rats. The study consisted of five groups of rats that were exposed to drinking water alone, EtOH alone at 5 g/kg, Mn alone at 30 mg/kg or co-expose with EtOH at 1.25 and 5 g/kg body weight by oral gavage for 35 consecutive days. The results indicated that the significant (p < 0.05) increases in pro-inflammatory cytokines, namely tumor necrosis factor alpha (TNF-alpha) and interleukin 1 beta (IL-1beta) as well as cyclooxygenase-2 (COX-2) and nuclear factor kappa B (NF-kappaB) activation in the hypothalamus following individual exposure to Mn and EtOH to rats were intensified in the co-exposure group. Moreover, immunohistochemistry analysis showed marked decrease in B cell lymphoma-2 (Bcl-2) protein expression as well as the increases in the apoptotic proteins, namely Bax and caspase-3 along with p53 in the hypothalamus of rats treated with Mn or EtOH alone were intensified in the co-exposure group. Taken together, these findings highlight that EtOH exacerbated the induction of inflammatory and apoptotic biomarkers via regulation of NF kappaB/p53 signaling pathways in the hypothalamus of rats. These alterations may have profound disrupting effects on the hypothalamus functions such as impairment of it metabolic and autonomic nervous system functions. PMID- 30284676 TI - Excessive corticosterone induces excitotoxicity of hippocampal neurons and sensitivity of potassium channels via insulin-signaling pathway. AB - Corticosterone (CORT) is a kind of corticosteroid produced by cortex of adrenal glands. Hypothalamic-pituitary-adrenal (HPA) axis hyperfunction leads to excessive CORT, which is associated with depression. Few studies have investigated the role of CORT in voltage-gated ion channels and its upstream signaling pathway in central nervous system. In this study, we investigated the mechanism of excessive CORT resulting in brain impairment on voltage-gated ion channels, and its upstream signaling effectors in hippocampal CA1 neurons. The action potential (AP) and voltage-gated potassium currents were determined by using whole-cell patch-clamp. Insulin and CORT improved the neuronal excitability. Independent effects existed in transient potassium channel (IA) and delay rectifier potassium channel (IK). The inhibition of potassium currents, IA in our experiment, could increase neuronal excitability. CORT led to the excitotoxicity of hippocampal neurons via phosphatidylinositol 3 kinase (PI3K) mediated insulin-signaling pathway. Therefore, the stimulation of excessive CORT induces excitotoxicity of hippocampal neurons and sensitivity of potassium channels via PI3K-mediated insulin-signaling pathway, which indicates one possible way of depression treatment. PMID- 30284677 TI - Alkaline phosphatase: a potential biomarker for stroke and implications for treatment. AB - Stroke is the fifth leading cause of death in the U.S., with more than 100,000 deaths annually. There are a multitude of risks associated with stroke, including aging, cardiovascular disease, hypertension, Alzheimer's disease (AD), and immune suppression. One of the many challenges, which has so far proven to be unsuccessful, is the identification of a cost-effective diagnostic or prognostic biomarker for stroke. Alkaline phosphatase (AP), an enzyme first discovered in the 1920s, has been evaluated as a potential biomarker in many disorders, including many of the co-morbidities associated with stroke. This review will examine the basic biology of AP, and its most common isoenzyme, tissue nonspecific alkaline phosphatase (TNAP), with a specific focus on the central nervous system. It examines the preclinical and clinical evidence which supports a potential role for AP in stroke and suggests potential mechanism(s) of action for AP isoenzymes in stroke. Lastly, the review speculates on the clinical utility of AP isoenzymes as potential blood biomarkers for stroke or as AP targeted treatments for stroke patients. PMID- 30284678 TI - Purkinje Neurons: Development, Morphology, and Function. AB - Cerebellar Purkinje neurons are arguably some of the most conspicuous neurons in the vertebrate central nervous system. They have characteristic planar fan-shaped dendrites which branch extensively and fill spaces almost completely with little overlap. This dendritic morphology is well suited to receiving a single or a few excitatory synaptic inputs from each of more than 100,000 parallel fibers which run orthogonally to Purkinje cell dendritic trees. In contrast, another type of excitatory input to a Purkinje neuron is provided by a single climbing fiber, which forms some hundreds to thousands of synapses with a Purkinje neuron. This striking contrast between the two types of synaptic inputs to a Purkinje neuron has attracted many neuroscientists. It is also to be noted that Purkinje neurons are the sole neurons sending outputs from the cerebellar cortex. In other words, all computational results within the cortex are transmitted by Purkinje cell axons, which inhibit neurons in the cerebellar or vestibular nucleus. Notably, Purkinje neurons show several forms of synaptic plasticity. Among them, long-term depression (LTD) at parallel fiber synapses has been regarded as a putatively essential mechanism for cerebellum-dependent learning. In this special issue on Purkinje neurons, you will find informative reviews and original papers on the development, characteristics and functions of Purkinje neurons, or related themes contributed by outstanding researchers.

AB - Autism spectrum disorder (ASD) is a set of neurodevelopmental conditions characterized by early-onset difficulties in social communication and unusually restricted, repetitive behavior and interests. Parental consanguinity may lead to higher risk of ASD and to more severe clinical presentations in the offspring. Studies of ASD families with high inbreeding enable the identification of inherited variants of this disorder particularly those with an autosomal recessive pattern of inheritance. In our study, using copy number variants (CNV) analysis, we identified a rare homozygous deletion in 2p11.2 region that affects ELMOD3, CAPG, and SH2D6 genes in a boy with ASD, intellectual disability (ID), and hearing impairment (HI). This deletion may reveal a new contiguous deletion syndrome in which ELMOD3, known to be implicated in autosomal recessive deafness underlies the HI of the proband and CAPG, member of actin regulatory proteins involved in cytoskeletal dynamic, an important function for brain development and activity, underlies the ASD/ID phenotype. A possible contribution of SH2D6 gene, as a part of a chimeric gene, to the clinical presentation of the patient is discussed. Our result supports the implication of ELMOD3 in hearing loss and highlights the potential clinical relevance of 2p11.2 deletion in autism and/or intellectual disability. PMID- 30284681 TI - Structural and copy number chromosome abnormalities in canine cutaneous mast cell tumours. AB - Mast cell tumours (MCTs) are the most common skin tumours in dogs. Their clinical behaviour is variable and their aetiology remains largely unknown. We performed a metaphase fluorescence in situ hybridisation (FISH) with whole chromosome painting probes, and interphase FISH with BAC probes for 14 cancer-related genes to reveal clonal structural chromosome rearrangements and copy number variants (CNVs) in canine cutaneous MCTs. The metaphase FISH performed in three MCTs revealed several clonal monosomies and trisomies and two different chromosome rearrangements. No centric fusions were detected. The interphase FISH showed a variety of low frequency CNVs for the individual cancer-related genes. The heterogeneous character of the detected abnormalities indicates increased chromosome instability in canine MCTs. The clonal gain of chromosome 11 was detected in 81% (13/16) of the MCTs. Further research is needed to evaluate the significance of this abnormality as prognostic factor for the survival time or recurrence risk assessments in canine cutaneous MCTs. PMID- 30284682 TI - Ruthenium pyridyl thiocyanate complex increased the production of pro inflammatory TNFalpha and IL1beta cytokines by the LPS stimulated mammalian macrophages in vitro. AB - Every cell in our body depends on the electron transport processes in order to generate energy and function properly. Being able to regulate the metabolic activity of a cell would enable us altering its function and eventually lead us to a desired biological outcome at the cellular level and more desirably at a systemic level. Immunomodulatory or immunostimulatory molecules have been focus of the recent studies in order to regulate or boost the activities of the immune system cells and suppress or eliminate the disease conditions such as cancer, autoimmune reactions, inflammatory disorders as well as infections. In our study we used a ruthenium pyridyl thiocyanate complex, K330, to examine its effect on the activity of the innate immune system cells, macrophages in vitro. K330 was our candidate due to its application in the solar cells. Especially, due to its ability to get involved in electron transfer systems we hypothesized that it could change the activity of the immune system cells at cellular level, possibly by interfering the electron transfer reactions of the cells. Our results support our hypothesis since K330 lead to a significant increase in TNFalpha and IL1beta cytokine production levels by LPS stimulated macrophages compared to only LPS treated control groups. Based on our in vitro results, K330 can also be utilized as an adjuvant candidate in vaccinations where the antigen itself is not sufficient to generate a proper immune response.

AB - This paper describes capacity development as a key aspect of community-based research with indigenous communities. University research engagement with indigenous communities includes extensive, and often negative, historical antecedents. We discuss strategies for developing effective, egalitarian, and balanced indigenous community-university relationships to build research capacity of these communities, and to create sustainable partnerships to improve health and wellness, and to reduce health disparities. We draw on the experience of eight investigators conducting research with indigenous communities to assess effective strategies for building and enhancing partnerships, including (1) supporting indigenous investigator development; (2) developing university policies and practices sensitive and responsive to Indigenous community settings and resources, and training for research; (3) developing community and scientifically acceptable research designs and practices; (4) aligning indigenous community and university review boards to enhance community as well as individual protection (e.g., new human subjects training for Indigenous research, joint research oversight, adaptation of shorter consent forms, appropriate incentives, etc.); (5) determining appropriate forms of dissemination (i.e., Indian Health Services provider presentation, community reports, digital stories, etc.); (6) best practices for sharing credit; and (7) reducing systematic discrimination in promotion and tenure of indigenous investigators and allies working in indigenous communities. PMID- 30284684 TI - Small intestinal bacterial overgrowth in cirrhosis: systematic review and meta analysis. AB - BACKGROUND: Small intestinal bacterial overgrowth (SIBO) was detected in cirrhosis in many studies. The aim is to perform a systematic review and meta analysis on the prevalence of SIBO in cirrhosis and on the relationship of SIBO with features of cirrhosis. METHODS: PUBMED search (until 14 January 2018) was performed. Specific search terms were: '(cirrhosis) AND (SIBO OR bacterial overgrowth)'. Studies not relating to cirrhosis or SIBO, animal studies, and non original articles were excluded. A meta-analysis of all studies was performed using a random-effects model. RESULTS: 117 references were identified by the PUBMED search. 3 references were added after handsearching the reference lists of all the articles. 99 references were excluded. 21 studies (included in total 1264 cirrhotics and 306 controls) remained for qualitative analysis and quantitative synthesis. Prevalence of SIBO for cirrhosis was 40.8% (95% CI 34.8-47.1), while the prevalence of SIBO for controls was 10.7% (95% CI 5.7-19.0). OR 6.83 (95% CI 4.16-11.21; p < 0.001). Prevalence of SIBO for decompensated cirrhosis was higher than prevalence of SIBO for compensated cirrhosis (50.5% vs. 31.2%; p < 0.001). SIBO in cirrhosis was associated with ascites (p < 0.001), minimal hepatic encephalopathy (p = 0.001), bacterial translocation (p = 0.026), spontaneous bacterial peritonitis (p = 0.008), prolonged orocecal transit time (p < 0.001), and was not associated with hypocoagulation. Further studies are required to clarify the relationship of SIBO with hyperbilirubinemia, hypoalbuminemia, overt hepatic encephalopathy in past, esophageal varices and systemic inflammation. CONCLUSION: Small intestinal bacterial overgrowth is more often detected in cirrhosis than in healthy persons and is associated with some features of cirrhosis. PMID- 30284685 TI - A phase II study of lenalidomide consolidation and maintenance therapy after autologous PBSCT in patients with multiple myeloma. AB - The efficacy and safety of lenalidomide (LEN) consolidation therapy and subsequent LEN maintenance therapy after high-dose therapy with autologous peripheral blood stem cell transplantation (auto-PBSCT) were evaluated in patients with newly diagnosed symptomatic multiple myeloma (MM). Forty-one patients were enrolled and received high-dose dexamethasone (DEX) therapy as an initial induction. The patients who did not respond to the DEX therapy were further treated with four cycles of bortezomib plus DEX (BD) induction therapy. For patients who responded to BD, PBSC harvesting was scheduled following high dose cyclophosphamide and filgrastim administration. After PBSC harvesting, high dose chemotherapy of melphalan with auto-PBSCT was performed. One hundred days after auto-PBSCT, patients received consolidation therapy consisting two cycles of LEN plus low-dose DEX (Ld) and LEN maintenance therapy. Only one death occurred during mobilization therapy, but the protocol developed in this study was considered generally safe to provide. Overall response rates after consolidation and maintenance therapies were 73.7% and 81.6%, respectively. Two year progression-free survival and overall survival were 76.3% and 92.1%, respectively. These observations suggest that LEN consolidation and maintenance therapy are effective and safe, and provide favorable response rates in patients with MM.

AB - We evaluated the accuracy and precision of a novel non-invasive monitoring device in comparison with conventional monitoring methods used in intensive care units (ICU). The study device was developed to measure blood pressure, pulse rate, respiratory rate, and oxygen saturation, continuously with a single sensor using the photoplethysmographic technique. Patients who were monitored with arterial pressure lines in the ICU were enrolled. Systolic and diastolic blood pressure, pulse rate, respiratory rate, and arterial oxygen saturation were measured continuously for 30 min at 5-min intervals using the conventional methods and the study device. The primary outcome variable was blood pressure. Blood pressure measured by the study device highly correlated with the arterial pressure line values (correlation coefficients > 0.95). Percent errors for systolic, diastolic and mean blood pressures were 2.4% and 6.7% and 6.5%, respectively. Percent errors for pulse rate, respiratory rate and oxygen saturation were 3.4%, 5.6% and 1.4%, respectively. The non-invasive, continuous, multi-parameter monitoring device presented high level of agreement with the invasive arterial blood pressure monitoring, along with sufficient accuracy and precision in the measurements of pulse rate, respiratory rate, and oxygen saturation. PMID- 30284688 TI - Retrospective Cohort Analysis of the Reduced Burden of Hypoglycemia Associated with Dipeptidyl Peptidase-4 Inhibitor Use in Patients with Type 2 Diabetes Mellitus. AB - INTRODUCTION: The use of antihyperglycemic agents (AHA), especially insulin and sulfonylureas (SU), is a risk factor for hypoglycemia. Despite the significant clinical and economic burdens associated with hypoglycemia and the decreasing use of SU in favor of other oral AHA, relatively little is known about hypoglycemia trends specific to the use of non-insulin AHA. We sought to estimate annual hypoglycemia event rates and costs among patients with type 2 diabetes mellitus (T2DM) who started either SU or dipeptidyl peptidase-4 inhibitors (DPP-4i) and to predict rates and costs in the absence of DPP-4i. METHODS: Truven's MarketScan Commercial Claims database was used to estimate hypoglycemia event rates and costs from 2007 to 2013. Hypoglycemia, defined using diagnosis codes, was assessed during the 12 months following SU (n = 245,201) or DPP-4i (n = 176,786) initiation by adults with T2DM. Coefficients from a Poisson regression model used to estimate the impact of patient characteristics on hypoglycemia rates for patients who started SU were used to predict rates for patients who started DPP 4i had they started SU instead. RESULTS: Hypoglycemia events per 100 patient years (costs per event) ranged from 5.4 ($565) in 2007 to 10.4 ($1154) in 2013 for patients starting SU; rates (costs) for patients starting DPP-4i ranged from 3.2 ($308) in 2007 to 6.4 ($482) in 2013. Predicted hypoglycemia rates would have been 5.3-9.9 per 100 person-years for patients who started DPP-4i had they started SU instead. Starting DPP-4i, rather than SU, would have resulted in national savings of $750.3 million in healthcare costs due to avoided hypoglycemia events during this period. CONCLUSIONS: Hypoglycemia rates and costs were consistently higher for patients who started SU rather than DPP-4i. The overall burden of hypoglycemia could be lowered substantially in the USA if, when feasible, patients with T2DM initiate DPP-4i instead of SU. FUNDING: Merck & Co., Inc., Kenilworth, NJ USA. PMID- 30284689 TI - Investigating the Reliability of HbA1c Monitoring for Blood Glucose Control During Late Pregnancy in Patients with Gestational Diabetes Mellitus (GDM) with and without beta-Thalassemia Minor. AB - INTRODUCTION: Patients with gestational diabetes mellitus (GDM) need strict blood glucose control to reduce the incidence of perinatal complications in the mother or infant. The purpose of this study was to investigate whether the glycated hemoglobin (HbA1c) values of GDM patients were affected by beta-thalassemia minor and to subsequently discuss the limitations of HbA1c monitoring for blood glucose control. METHODS: 41 GDM patients with beta-thalassemia minor were enrolled to serve as the study group. 93 GDM patients without thalassemia were randomly selected as a control group. Clinical data on the 134 mothers as well as their newborns were retrospectively analyzed. The blood glucose values of the participants at various times during the gestation period were compared between the groups, as were their HbA1c and ferritin levels and iron deficiency rates in late pregnancy (36-38 weeks of gestation). Pearson's coefficient was calculated to determine the correlations between HbA1c and ferritin in both the study and control groups. RESULTS: The study and control groups did not show any significant differences in newborn birth weight, maternal age, maternal pre pregnancy body mass index (BMI), gestational age, newborn sex, gravidity, and parity. The blood glucose values of the participants at different times during the gestation period also did not differ significantly between the study group and the control group. However, the late-pregnancy HbA1c level (5.23 +/- 0.49%) and iron deficiency rate (12.19%) in the study group were significantly lower than those in the control group (5.42 +/- 0.43% and 58.06%, respectively); P < 0.05. Also, the late-pregnancy ferritin level in the study group (46.59 +/- 18.03 ng/mL) was significantly higher than that in the control group (25.58 +/- 11.42 ng/mL); P < 0.05. In addition, a significant negative correlation was observed between HbA1c and ferritin in both the study group (R = - 0.459, P = 0.003) and the control group (R = - 0.358, P = 0.010). CONCLUSIONS: The HbA1c level is affected by many factors. Using serum HbA1c values to monitor blood glucose in GDM patients with beta-thalassemia minor may lead to a mistaken assumption of low blood glucose levels, so HbA1c may not be a suitable indicator for monitoring blood glucose in pregnant women, particularly GDM patients with beta-thalassemia minor. PMID- 30284690 TI - A clinical compilation of lymph node pathologies comparing the diagnostic performance of biopsy methods. AB - PURPOSE: It is critical to obtain sufficient tissue, both in quality and quantity, in biopsy applications for histopathological review. Our aim was to compare fine-needle aspiration cytology (FNAC) and core needle biopsy (CNB) techniques in terms of their diagnostic performance in lymph node biopsies. This was a clinical compilation, and histopathological results from biopsies were also evaluated. METHODS: A total of 242 patients and 246 lymph nodes were prospectively evaluated. All histopathologic specimens were obtained through ultrasonography-guided biopsies performed at our institute between April 2015 and October 2017. Histopathological results were grouped according to diagnostic performance, and the mean performance scores of the two methods were compared. RESULTS: For FNAC, the mean diagnostic score was calculated to be 1.63, whereas for CNB, the mean diagnostic score was calculated to be 1.89. The difference between diagnostic scores of the two techniques was statistically significant (p < 0.01). CONCLUSION: We recommend that interventional radiologists perform vacuum assisted biopsies if there are no financial hindrances or evidence of psychological issues in patients. We recommend this not only for lymph nodes of malignant appearance but also for those that appear benign. PMID- 30284691 TI - Adaptation to Occupational Exposure to Moderate Endotoxin Concentrations: A Study in Sewage Treatment Plants in Germany. AB - Acute or chronic inhalation of endotoxin may lead to changes of lung function and inflammatory markers in the airways. Adaptation to workplace exposure may be possible. In this study, we investigated the possible difference in inflammatory markers assessed in nasal lavage fluid (NALF) in chronical exposure compared to voluntary subjects exposed acutely to endotoxin. We sought to define the variability of inflammatory markers in NALF and the dose-related changes after moderate exposure in naive subjects. Endotoxin exposure (4-1039 EU/m3) resulted from routine work during one shift in sewage treatment plants. Subjects were matched to pairs (8 workers escorted by 10 students). Inflammatory markers were investigated before, directly after, and 16 h after the shift end. Additional NALF samples were collected in students without any specific exposure after 3 days. In NALF, total cell count, and interleukin (IL)-8 and IL-1beta concentrations were significantly higher in workers than in students at all times pointing to workplace-related long-lasting exposure resulting in adaptation. However, concentration of inflammatory markers without specific exposure in students showed a great variability, covering the whole range of values recorded in the workers. The findings of this study make us to recommend a repeated assessment of inflammatory markers in healthy volunteers before the investigation of exposure-related changes and a sample size adequate for statistical analysis. PMID- 30284692 TI - Osteoprotegerin, Receptor Activator of Nuclear Factor Kappa B Ligand, and Growth Hormone/Insulin-Like Growth Factor-1 Axis in Children with Growth Hormone Deficiency. AB - The growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis is involved in the regulation of the receptor activator of nuclear factor kappa B ligand (RANKL)/RANK/osteoprotegerin (OPG) system, but the exact mechanism of the associations is not fully explained. In this study we investigated the serum OPG and total sRANKL concentrations in short children who had differences in GH secretory status. We also investigated the associations between the GH/IGF-1 and OPG/RANKL systems in GH-deficient children during GH treatment. There were no significant differences in any anthropometric or biochemical parameters evaluated between the GH-deficient and GH-sufficient children. The OPG content and total alkaline phosphatase (ALP) activity increased significantly after the initiation of GH treatment, while total sRANKL remained unchanged. The variables baseline BMI SDS for height-age (beta = 0.42; p < 0.05), baseline ALP activity (beta = 0.36; p < 0.05), weight SDS for height-age at 6 months of GH treatment (beta = 1.86; p < 0.01), and total ALP activity at 6 months of GH treatment (beta = 0.48, p < 0.01) were identified as independent predictors of DeltaOPG6-month-baseline. We conclude that OPG and total sRANKL concentrations are independent from GH secretory status in short children. OPG elevation during GH treatment is independently associated with total ALP activity and nutritional status in GH deficient children. PMID- 30284693 TI - Time for a Different Approach to Anterior Cruciate Ligament Injuries: Educate and Create Realistic Expectations. AB - Following an anterior cruciate ligament (ACL) injury, patients are often reassured that timely surgery followed by intensive physiotherapy will "fix their knee". Not only does this message create a false perception of uncomplicated return to sport (RTS), it also ignores the large body of evidence demonstrating a high RTS re-injury rate following ACL reconstruction. In this article, we propose an individualised approach to the management of ACL injuries that targets a shift away from early surgery and towards conservative management, with surgery 'as needed' and rehabilitation tailored to the patient's RTS goals. Education on the natural history of ACL injuries will ensure patients are not misguided into thinking surgery and intensive rehabilitation guarantees great outcomes. Further, understanding that conservative management is not inferior to surgery-and not more likely to cause knee osteoarthritis-will help the patient make an informed decision. For patients who opt for surgical management, rehabilitation must target strength and functional performance, avoid rapid increases in training load, and be guided by an RTS timeframe that is no shorter than 9 months. The content of rehabilitation should be similar for patients who opt for non operative management, although the RTS timeframe will likely be shorter. All patients should receive education on the relationship between injury risk and training load, and understand that a home-exercise program is not inferior to intensive physiotherapist-led exercise.

AB - The aim of the present study is to show how molecular topology can be a powerful in silico tool for the prediction of the fungicidal activity of several diphenylamine derivatives against three fungal species (cucumber downy mildew, rice blast and cucumber gray mold). A multi-target QSAR model was developed, and two strategies were followed. First is the construction of a virtual library of molecules using DesMol2 program and a subsequent selection of potential active ones. Second is the selection of molecules from the literature on the basis of molecular scaffolds. More than 700 diphenylamine derivatives designed and other 60 fluazinam's derivatives with structural similarity higher than 80% were studied. Almost twenty percent of the molecules analyzed show potential activity against the three fungal species.

AB - PURPOSE: We aimed to investigate that change of IPI values after sedation of patients undergoing cataract surgery under sedation. METHODS: We included 50 patients (ASA I-III) undergoing cataract surgery under sedation by phacoemulsification method in this prospective observational study. IPI, SpO2, ETCO2, respiratory rate (RR), peripheral pulse rate (PR), hemodynamic data and BIS values and perioperative complications were recorded. RESULTS: Compared to baseline values, RR value at 5th min, RR, PR, IPI values at 10th min and RR, PR values at 15th min were significantly low and heart rate value at 15th min and arterial pressure, bispectral index (BIS) values at 5th min, 10th min, 15th min, 20th min, 25th min and 30th min were lower than baseline values. CONCLUSIONS: IPI monitoring will provide guidance during sedation of patients with comorbid diseases undergoing cataract surgery by phacoemulsification method.

AB - In this study, we examined factors that affected milk production by cows raised in a temperate climate area. We conducted this study on a large dairy farm containing approximately 2000 Holstein cows, located in a temperate climate area. We collected 7803 calving records for 4069 cows from 2012 to 2016. We then assessed the effect of hot weather on milk yield by examining three climate factors: season, maximum temperature (MAX), and the temperature and humidity index (THI). We found that increases in heat stress caused linear decreases in milk yield (P < 0.05). Additionally, the effects of the three climate factors on milk yield varied depending on cow parity and days open (P < 0.05). Thus, management procedures should consider cow parity and lactating stage to minimize the negative effects of heat stress on milk production. We also found that the lowest Akaike information criterion value was obtained in our model when using THI for 305-day milk yield. This suggests that THI is a more accurate variable for evaluating heat stress than MAX or season. PMID- 30284697 TI - Major ion and dissolved heavy metal geochemistry, distribution, and relationship in the overlying water of Dongting Lake, China. AB - Deteriorating lake water quality has become a serious environmental issue around the globe. Heavy metals dissolved in the overlying water of lakes are notably more toxic than those found in lake sediment. Given this, we sought to better understand the characteristics of particular major ion and dissolved heavy metal in Dongting Lake-the second largest freshwater lake in China. Overlying water samples were collected from Dongting Lake to investigate the major ion geochemistry and to examine the relationship between the major ions and dissolved heavy metals. Chemical analysis of the overlying water showed that the average cation concentration was the highest for Ca2+, followed by Mg2+, Na+, and K+. Similarly, the highest anion concentration was SO42-, followed by Cl-, NO3-, and HCO3-. Total dissolved solids in the overlying water of Dongting Lake ranged from 66.19 to 159.20 mg/L, with an average value of 93.13 mg/L. The predominant hydrochemical type was Ca-SO4. The mean concentrations of dissolved heavy metal in both surface and deep waters decreased in the following order: Zn > Cr > Ni > Cu > Pb > Cd. Importantly, all of the selected heavy metals tested in the overlying water were lower than the corresponding toxicity reference values. Co occurrence network analyses were performed and compared the correlations between all measured major ions and heavy metals. Results of the subsequent principal component analyses revealed that heavy metal levels in the aquatic environment primarily originated from natural processes and were enhanced by anthropogenic activities.

PMID- 30284699 TI - Impaired Renal Function May Not Negate the Efficacy of Tolvaptan in the Treatment of Cirrhotic Patients with Refractory Ascites. AB - BACKGROUND AND OBJECTIVE: Tolvaptan, an oral vasopressin V2 receptor antagonist, has been widely used for the treatment of patients with cirrhosis and ascites. However, its efficacy in patients with renal dysfunction remains unknown. The objective of this study was to investigate the efficacy and safety of tolvaptan in patients with decompensated cirrhosis and severe chronic kidney disease (s CKD). METHODS: We studied 43 patients with liver cirrhosis who received tolvaptan (7.5 mg/day) for refractory ascites. s-CKD was defined as an estimated glomerular filtration rate (eGFR) < 45 mL/min/1.73 m2. Response to tolvaptan was defined as weight loss >= 1.5 kg in 7 days of treatment. RESULTS: Eighteen patients (42%) had s-CKD (s-CKD group), while the other 25 patients (58%) did not have s-CKD (n CKD group). Rates of response to tolvaptan were similar: 68% in the n-CKD group and 56% in the s-CKD group. Urine volumes increased significantly from baseline to day 7 in both groups. Incidences of adverse events were also similar (P = 0.93). Mean eGFR did not decline even in the s-CKD group (27.3 +/- 2.2 mL/min/1.73 m2 at baseline vs. 26.6 +/- 2.3 mL/min/1.73 m2 on day 7; P = 0.9). The cumulative survival rate did not differ significantly between the n-CKD and s CKD groups. In the s-CKD group, responders obtained a better prognosis than non responders. CONCLUSIONS: Tolvaptan significantly increased urine volumes similarly in patients with s-CKD and n-CKD without affecting renal function. As responders achieved a better prognosis, tolvaptan could be a good option to treat ascites in patients with cirrhosis and s-CKD. PMID- 30284700 TI - Safety and Plasma Concentrations of a Cyclin-dependent Kinase 9 (CDK9) Inhibitor, FIT039, Administered by a Single Adhesive Skin Patch Applied on Normal Skin and Cutaneous Warts. AB - BACKGROUND: Cutaneous warts are caused by human papilloma virus (HPV) infection. FIT039, a specific inhibitor of CDK9, suppresses the proliferation of DNA viruses in vitro. PURPOSE: We evaluated the safety, plasma concentrations, and efficacy of FIT039 delivered by single application of an adhesive skin patch on normal back skin and cutaneous warts. PATIENTS AND METHODS: In this placebo-controlled, dose-escalation, open-label, two-cohort phase I/II clinical trial, after a single administration of a 1% FIT039 patch, 3% FIT039 patch, or placebo on back skin, patients with cutaneous warts were treated with cryotherapy followed by a 1% FIT039 patch for 24 h in the first cohort. In the second cohort, cutaneous warts were treated with cryotherapy followed by a 3% FIT039 patch for 24 h. Adverse events and adverse drug reactions, the concentrations of FIT039, and surface area of cutaneous warts were evaluated. RESULTS: Neither irritant reactions nor symptoms related to FIT039 occurred when the FIT039 patches were applied to patients' backs or on warts in ten patients. The concentrations of FIT039 were under 0.1 ng/ml at every time point. The median wart surface area at 1 week after application of the 1% FIT039 patch was similar to baseline, while that of the 3% FIT039 patch was smaller than baseline. CONCLUSION: The FIT039 patch showed no topical or systemic adverse reactions when applied on normal skin or cutaneous warts. The safety and good adherence of the FIT039 patch are encouraging and support further studies to evaluate the efficacy of FIT039 in patients with cutaneous warts.

AB - We describe a rare case of recurrent pancreatic metastasis of intraductal tubulopapillary neoplasm (ITPN). A 53-year-old woman diagnosed with an intraductal papillary mucinous neoplasm (IPMN) and a pancreatic ductal adenocarcinoma (PDAC) of the pancreatic body underwent a distal pancreatectomy. The tumor was composed of cuboidal, high-grade dysplastic cells proliferating in a tubulopapillary growth pattern without mucin production; hence, the final diagnosis was ITPN. A follow-up computed tomography scan revealed an enhanced 2 cm mass of the pancreatic head 3 years after the surgery. From workup investigations, the patient was diagnosed with PDAC or a recurrent ITPN of the remnant pancreas. A total remnant pancreatectomy was then performed. Histopathological findings revealed that the new ITPN had the same features as the prior ITPN. In IPMNs, the presence of an invasive component and high-grade dysplasia can lead to progression to a recurring IPMN and the development of PDAC. Because there have been few reports of recurrent ITPN developing into PDAC, the risk factors for ITPN have not been investigated. Because of the uncertain clinicopathological characteristics of ITPN, more data should be gathered to assess the long-term outcome and malignant potential of ITPN. PMID- 30284704 TI - PF-06438179/GP1111: An Infliximab Biosimilar. AB - PF-06438179/GP1111 (Zessly(r); Ixifi(r)) [hereafter referred to as GP1111] is a biosimilar of the reference monoclonal anti-TNF-alpha antibody infliximab, and is approved in the EU and USA for the same indications as the reference drug, including rheumatoid arthritis (RA), Crohn's disease, ulcerative colitis (including paediatric ulcerative colitis in the EU), ankylosing spondylitis, psoriatic arthritis and plaque psoriasis; GP1111 is also approved in Japan. GP1111 has similar physicochemical characteristics and pharmacodynamic properties to those of reference infliximab, and the pharmacokinetic similarity of the agents has been shown in healthy volunteers and patients with moderate-to-severe RA despite methotrexate therapy. GP1111 demonstrated clinical efficacy equivalent to that of reference infliximab in patients with moderate-to-severe RA, despite methotrexate therapy, and was generally well tolerated in this population. The tolerability, immunogenicity and safety profiles of GP1111 were similar to those of reference infliximab, and switching from reference infliximab to GP1111 had no impact on safety, efficacy or immunogenicity. The role of reference infliximab in the management of autoimmune inflammatory conditions is well established and GP1111 provides an effective biosimilar alternative for patients requiring infliximab therapy. PMID- 30284705 TI - PET-MRI for the Study of Metabolic Bone Disease. AB - PURPOSE OF REVIEW: This review article attempts to summarize the current state and applications of the hybrid imaging modality of PET-MRI to metabolic bone diseases. The advances of PET and MRI are also discussed for metabolic bone diseases as potentially applied via PET-MRI. RECENT FINDINGS: Etiologies and mechanisms of metabolic bone disease can be complex where molecular changes precede structural changes. Although PET-MRI has yet to be applied directly to metabolic bone disease, possible applications exist since PET, specifically 18F NaF PET, can quantitatively track changes in bone metabolism and is useful for assessing treatment, while MRI can give detailed information on bone water concentration, porosity, and architecture through novel techniques such as UTE and ZTE MRI. Earlier detection and further understanding of metabolic bone disease via PET and MRI could lead to better treatment and prevention. More research using this modality is needed to further understand how it can be implemented in this realm.

PMID- 30284706 TI - EGFR Amplification and Sensitizing Mutations Correlate with Survival in Lung Adenocarcinoma Patients Treated with Erlotinib (MutP-CLICaP). AB - BACKGROUND: Non-small cell lung cancer (NSCLC) has a 5-year survival of 5-16%. Epidermal growth factor receptor (EGFR) mutations, in most cases, confer sensitivity to EGFR tyrosine kinase inhibitor (TKI) therapy. Nonetheless, it is still unclear why clinical outcomes vary among patients with identical EGFR mutations. The amplification of the EGFR gene (EGFRamp) may play a significant role. OBJECTIVE: Compare the complete (CR) and partial response (PR) rates, overall survival (OS), and progression-free survival (PFS) in Hispanic patients with lung adenocarcinoma treated with erlotinib with EGFR mutations (L858R or exon 19 deletion [Del19]) with and without concomitant EGFRamp. PATIENTS AND METHODS: Seventy-two EGFR-positive lung adenocarcinoma patients of Hispanic origin, who underwent first-line treatment with erlotinib, were evaluated for EGFRamp by fluorescence in situ hybridization (FISH). The clinical outcomes were analyzed according to EGFR mutations and EGFRamp status. RESULTS: 30.6% of samples showed EGFRamp, more frequently present in patients with Del19 (p = 0.05). Patients with EGFRamp had a longer PFS (in months) [(28.5, 95% CI 22.3 34.6) vs. (11.0, 95% CI 8.2-16.7); p = 0.002] and OS [(37.8, 95% CI 30.9-44.7) vs. (27.1, 95% CI 12.8-41.3); p = 0.009] than those without. EGFRamp significantly influenced the response to erlotinib (p = 0.0001). EGFRamp+/Del19 had a longer OS, 37.8 (95% CI 31.0-44.6), compared to EGFRamp+/L8585R, 27.5 (95% CI 12.4-42.5) (p < 0.001) and longer PFS (p = 0.043). CONCLUSION: Among Hispanic patients, EGFRamp was present in 30% of patients with EGFR mutations. EGFR mutations and EGFRamp are associated with better OS, PFS, CR, and PR to erlotinib and, hence, could aid in the correct selection of patients that benefit from EGFR TKI treatment. PMID- 30284708 TI - Effect of biodiesel on PAH, OPAH, and NPAH emissions from a direct injection diesel engine. AB - Polycyclic aromatic hydrocarbon (PAH), oxy- and nitro-derivate PAH (OPAH and NPAH) emissions from a direct injection diesel engine fueled with conventional fossil diesel (D), waste cooking oil biodiesel (B100), and their two blends (B20 and B50) were compared. The results show that B100 can reduce low molecular weight PAHs such as naphthalene, acenaphthylene, and fluorene as much as 90% compared with diesel. However, the emissions of high molecular weight PAHs including benzo[b]fluoranthene, benzo[k]fluoranthene, and benzo[a]pyrene decrease slightly when using B100. The emission levels for PAHs and OPAHs present comparable, while NPAH emission levels are five to ten times lower than those of PAHs and OPAHs. Compared with diesel, PAH and NPAH emissions significantly decrease. On the contrary, an increase trend of OPAH emission has been observed with adding biodiesel. For the specific parent PAHs and its oxygenated and nitrated derivatives, the fractions of parent PAHs gradually decrease with increasing biodiesel content in the blends, while the corresponding oxygenated and nitrated derivative fractions observably increase, especially for the high molecular weight compounds. Considering the increase of OPAH and NPAH fractions in total particle-phase PAHs when using biodiesel, in-depth biodiesel cytotoxicity assessment should be conducted. PMID- 30284709 TI - The content of the potentially toxic elements, iron and manganese, in the grapevine cv Tamjanika growing near the biggest copper mining/metallurgical complex on the Balkan peninsula: phytoremediation, biomonitoring, and some toxicological aspects. AB - Plants growing in areas polluted by heavy metals represent excellent models for the investigations related to their potentials for hazardous metals accumulation which further may help in the estimation of plant practical biomonitoring and phytoremediation potentials. In this study, the potentials of the grapevine cultivar Tamjanika from a highly polluted region in Eastern Serbia, with intensive copper mining and metallurgical activities, were estimated in regard to the potentially toxic elements such as iron and manganese; the potential danger from these metals through fruit consummation is also considered. Used methods were the following: ICP-OES analysis, calculation of biological coefficients, the Pearson correlation study, one-way ANOVA, and hierarchical cluster analysis. The results revealed that a great majority of the recorded concentrations in different plant organs were in the range of normal concentrations, as well as that the calculated accumulation rates for both metals were very low. The data also pointed to generally minimal to moderate enrichment by these metals which represents totally dissimilar situation in comparison with other heavy metals detected in the very same plant samples. The results of this study suggested that the investigated plants of the grapevine cv Tamjanika assimilated iron and manganese predominately according to their individual needs, and confirmed that the utilization of this plant species can be very effective in different biomonitoring procedures and also in the phytoremediation procedure known as phytostabilization. At the same time, it was obvious that even in aggressive circumstances its fruit was protected from some serious contamination and kept pretty safe for consummation. PMID- 30284711 TI - Early plant growth and bacterial community in rhizoplane of wheat and flax exposed to silver and titanium dioxide nanoparticles. AB - Silver and titanium dioxide nanoparticles (AgNPs and TiO2NPs) are highly useful, but they are also a significant reason for concern as they exert toxicity. The goal of research was to assess the role of three kinds of NPs in concentrations of 100 mg L-1 on early growth plants (wheat, flax) and bacterial community in rhizoplane. Titanium (IV) oxide anatase (TiO2NPs1) and titanium (IV) oxide nanopowder (TiO2NPs2) are commercial products. A suspension of AgNPs was prepared via a procedure of reduction with tannic acid. The response of Monocot and Dicot growth form plants to the tested NPs was different. Germination and seedling growth of wheat treated with TiO2NPs1 was better. The response of flax to NPs was noted as an increase of chlorophyll content. The bacterial community in wheat rhizoplane was not significantly modified, but there was a declining trend. In turn, a difference in the surface charge of NPs had an influence on the total bacterial community in Dicot rhizoplane. Positively charged TiO2NPs2 significantly decreased the quantity of total bacteria in contrast to negatively charged AgNPs and TiO2NPs1 which increased it. A qualitative analysis did not confirm the influence of the surface charge of NPs on an increase/decrease in the quantity of Pseudomonas and Bacillus bacteria, but did show that there was no toxicity of the tested NPs to the plant growth-promoting bacteria community. The rhizoplane microbiome was dependent on the species of plant, and the bacteria found in the communities are sensitive to NPs to a varying degree. PMID- 30284712 TI - Summer fallow increases loss of residual nitrogen fertilizer in dryland of the Loess Plateau: a 15N-labeled method. AB - Summer fallow is very common in dryland agriculture to conserve rainwater and replenish soil fertility. However, bare land and intensive rainfall during summer fallow might result in a potential risk of N loss. We used a 15N-labelling method to study the loss of residual N fertilizer during summer fallow and its use by next wheat in the Loess Plateau. Our study included three treatments: without the addition of N (N0W0), with the addition of 50 kg ha-1 N (NW0) and with the addition of 50 kg ha-1 N plus 35% more water (NW). The N fertilizer (K15NO3) in solution was injected into the soil at a depth of 35 cm of the polyvinyl chloride (PVC) columns in field. The fates of 15N were followed after summer fallow and in the next season's wheat (Triticum aestivum L.). The summer fallow of this study was a dry summer; however, fertilizer 15N was still leached down to 40-cm depth for the NW0 treatment; and for the NW treatment, the peak of 15N fertilizer was approximately 20 cm deeper. After summer fallow, the loss of the initially applied 15N was 26% in the soil profile for the NW0 treatment; and for the NW treatment, it increased to 37%. Soil 15N abundance in 0-20 cm of the NW0 and NW treatments was higher than the N0W0 treatment, indicating the upward movement of 15N in summer fallow. After the next wheat harvest, 15N uptake by wheat in the NW treatment decreased from 21.0 to 18.6% compared to the NW0 treatment. High rainfall during summer fallow increased residual N loss during summer fallow but decreased its use by the next crop. PMID- 30284713 TI - Effective reduction of metronidazole over the cryptomelane-type manganese oxide octahedral molecular sieve (K-OMS-2) catalyst: facile synthesis, experimental design and modeling, statistical analysis, and identification of by-products. AB - High concentrations of antibiotic compounds within pharmaceutical wastewater have hazardous impacts toward environment and human health. Therefore, there is an immediate requirement of efficient treatment method for removal of antibiotics from aquatic environment. In the present study, the cryptomelane catalyst-type manganese oxide octahedral molecular sieve (K-OMS-2) was synthesized in the presence of benzyl alcohol as a reducing agent and cetyltrimethylammonium bromide as a structure-directing agent and then utilized to reduce the metronidazole. The central composite design method was the experimental design adopted. The FESEM analysis revealed that the K-OMS-2 surface contained many uniformly cylindrical aggregates less than about 40 nm in diameter and about 80-100 nm in length. Besides, a high specific surface area of 129 m2/g and average pore size of 45.47 nm were recorded. According to the TGA/DTA analysis, the prepared catalyst revealed high thermal stability. The maximum metronidazole degradation (95.36%) was evident at conditions of pH = 3, catalyst mass = 0.97 g/L, contact time = 200 min, and metronidazole concentration = 20 mg/L. Metronidazole did not form a complex with nitrate, fluoride, sulfate, or hardness. These ions exerted a negligible effect on metronidazole reduction using the K-OMS-2 catalyst, except for hardness, which reduced the removal efficiency of metronidazole by 17%. The FTIR and LC-MS revealed a complex mechanism involved in the metronidazole degradation by the K-OMS-2 involving the formation of an amino group, a hydroxyelated compound via N-denitration, and hydrogenation process on the K-OMS 2 catalyst surface.

Thus, the present review paper aims to summarize the current evidences and findings on the effect of air pollution on lung function in both humans and animals. PMID- 30284715 TI - Postoperative pain after spinal surgery in the paediatric population. AB - INTRODUCTION: Postoperative pain is a major aftereffect of surgery. Especially severe occurs after extensive operations within the spine. The goal of the study was to investigate the laboratory predictive factors of intensive postoperative pain in children undergoing extensive surgery Patients and methods: We recruited 41 children, age median 13 years (IQR:10-15 years) undergoing extensive spine surgery. The subjects were divided into two groups based on the intensity of postoperative pain measured using the 10-point numerical rating scale (NRS), visual analog scale (VAS) or faces pain scale-revised (FPS-R). Patients with a score of 5 or higher were included in the study group and those with NRS of less than 5 were included in the control group. We collected detailed clinical and laboratory data before, during and after surgery. RESULTS: The highest intensity of pain was observed in the first 6 hours after surgery. The postoperative pain was associated with a higher drop in hemoglobin concentration and hematocrit level in peri-operative period (p=0.006 and p=0.019 respectively) as well as higher changes in mean arterial pressure during surgery. Additionally, we found that children with intensive pain had higher total protein concentration after surgery. CONCLUSIONS: We reported that the drop in hemoglobin and hematocrit level, fluctuation in mean arterial pressure as well as total protein concentration could be useful prognostic factors of early postoperative pain. < p > < /p >.

PMID- 30284717 TI - R-spondin 2 promotes osteoblastic differentiation of immature human periodontal ligament cells through the Wnt/beta-catenin signaling pathway. AB - OBJECTIVE: In this study, we measured the expression of R-spondin 2 (RSPO2) in periodontal ligament (PDL) tissue and cells. Further, we examined the effects of RSPO2 on osteoblastic differentiation of immature human PDL cells (HPDLCs). BACKGROUND: R-spondin (RSPO) family proteins are secreted glycoproteins that play important roles in embryonic development and tissue homeostasis through activation of the Wnt/beta-catenin signaling pathway. RSPO2, a member of the RSPO family, has been reported to enhance osteogenesis in mice. However, little is known regarding the roles of RSPO2 in PDL tissues. METHODS: Expression of RSPO2 in rat PDL tissue and primary HPDLCs was examined by immunohistochemical and immunofluorescence staining, as well as by semiquantitative RT-PCR. The effects of stretch loading on the expression of RSPO2 and Dickkopf-related protein 1 (DKK1) were assessed by quantitative RT-PCR. Expression of receptors for RSPOs, such as Leucine-rich repeat-containing G-protein-coupled receptors (LGRs) 4, 5, and 6 in immature human PDL cells (cell line 2-14, or 2-14 cells), was investigated by semiquantitative RT-PCR. Mineralized nodule formation in 2-14 cells treated with RSPO2 under osteoblastic inductive condition was examined by Alizarin Red S and von Kossa stainings. Nuclear translocation of beta-catenin and expression of active beta-catenin in 2-14 cells treated with RSPO2 were assessed by immunofluorescence staining and Western blotting analysis, respectively. In addition, the effect of Dickkopf-related protein 1 (DKK1), an inhibitor of Wnt/beta-catenin signaling, was also examined. RESULTS: Rat PDL tissue and HPDLCs expressed RSPO2, and HPDLCs also expressed RSPO2, while little was found in 2-14 cells. Expression of RSPO2 as well as DKK1 in HPDLCs was significantly upregulated by exposure to stretch loading. LGR4 was predominantly expressed in 2 14 cells, which expressed low levels of LGR5 and LGR6. RSPO2 enhanced the Alizarin Red S and von Kossa-positive reactions in 2-14 cells. In addition, DKK1 suppressed nuclear translocation of beta-catenin, activation of beta-catenin, and increases of Alizarin Red S and von Kossa-positive reactions in 2-14 cells, all of which were induced by RSPO2 treatment. CONCLUSION: RSPO2, which is expressed in PDL tissue and cells, might play an important role in regulating the osteoblastic differentiation of immature human PDL cells through the Wnt/beta catenin signaling pathway.

AB - OBJECTIVES: To describe the presentation, influence of previous treatment and diagnosis in juvenile dogs presenting with pyrexia to a UK referral centre. MATERIALS AND METHODS: Clinical records of dogs aged 1 to 18 months presenting with a problem list including pyrexia (>=?39?2 degrees C) that was reproducible during referral hospitalisation were retrospectively reviewed. Signalment, history - including previous treatment, clinical examination findings and diagnosis were recorded. Diagnoses were categorised as non-infectious inflammatory, infectious, congenital, neoplastic and miscellaneous. The influence of previous treatment on the ability to reach a final diagnosis was analysed. RESULTS: A total of 140 cases were identified. Diagnosis was reached in 115 cases. Non-infectious inflammatory disease was identified in 91 cases (79%), infectious disease in 19 cases (17%), a congenital disorder in four dogs (3%) and neoplasia in one dog (1%). Breeds most commonly identified were Border collies (17/140; 12%), beagles (16/140; 11%), Labrador retrievers (11/140; 8%), springer spaniels (9/140; 6%) and cocker spaniels (8/140; 6%). Before presentation, most dogs had received antibiotics (83/140; 59%), non-steroidal anti-inflammatory drugs (84/140; 60%) or steroids (9/140; 6%), either alone or in combination. Neither antibiotics nor non-steroidal anti-inflammatory drugs influenced the ability to reach a diagnosis. Steroid-responsive meningitis-arteritis comprised 55 of 91 (60%) individuals of the non-infectious inflammatory cohort. All four dogs diagnosed with congenital disorders were Border collies. CLINICAL SIGNIFICANCE: Non-infectious inflammatory disease, particularly steroid responsive meningitis-arteritis, immune-mediated polyarthritis and metaphyseal osteopathy, was commonly diagnosed in this population of pyrexic juvenile dogs. PMID- 30284719 TI - Association between missed canals and apical periodontitis. AB - AIM: To evaluate the frequency of post-treatment apical periodontitis associated with root filled teeth with at least one untreated root canal. METHODOLOGY: Eight hundred and seven cone beam computed tomography images containing at least one root filled tooth were selected from a collection of 1543 images from Brazilian individuals. Scans were taken using ICAT Classic devices (Imaging Sciences, Hatfield, PA, USA) in a private oral radiology clinic from January to April 2015. All root filled teeth were analysed for the presence of missed canals and apical periodontitis. The chi-square and odds ratio tests were used to verify if there were an association and risk relationship between the occurrence of untreated canals and apical periodontitis. RESULTS: A total of 2294 teeth with evidence of root fillings were identified. Two hundred and eighty-one teeth had at least one untreated missed canal (12%). The frequency of apical periodontitis in teeth with at least one untreated canal was significantly greater in comparison to teeth with all canals treated (274/281, 98% versus 1736/2013, 86%) (P < 0.01). The odds for apical periodontitis to be present was 6.25 times greater for teeth with an untreated canal. The mesiobuccal roots of maxillary first molars had the greatest frequency of untreated canals (114/154, 74%), with the second mesiobuccal canal being the most frequently missed (n = 106/114, 93%). CONCLUSION: Root filled teeth with at least one missed canal had a high prevalence of post-treatment apical periodontitis. PMID- 30284720 TI - Income inequality, perceived competitiveness, and approach-avoidance motivation. AB - OBJECTIVE: Scholars disagree on whether income inequality has incentive or disincentive effects. In the present research, we move beyond such debate and focus on the motivational processes that income inequality predicts. First, income inequality makes economic stratification salient; therefore, it should promote perceived competitiveness. Second, competitiveness can be appraised as both a challenge and a threat; therefore, it should promote both approach and avoidance motivation. METHOD: In three studies (N = 2,543), U.S. residents from various ZIP codes reported the extent to which they perceived competitiveness in their town/city (Studies 1-3), as well as their economic achievement goals, achievement motives, and self-regulatory foci (Studies 2-3). RESULTS: Level of local income inequality was found to be a positive predictor-via increased perceived competitiveness-of other-approach economic goals, need for achievement, and promotion focus, as well as other-avoidance economic goals, fear of failure (specifically, the shame/embarrassment component), and prevention focus. Furthermore, actual and perceived income inequality were positively correlated. CONCLUSIONS: The conceptual and empirical work herein is the first to show how the economic environment predicts individuals' perceptions of competitiveness, influencing personal goals, motives, and orientations. It provides a more nuanced perspective on the implications of income inequality than perspectives currently available. PMID- 30284721 TI - Proteomic profile of root canal contents in teeth with post-treatment endodontic disease. AB - AIM: To characterize the proteome of 20 root canals in teeth with post-treatment endodontic disease using mass spectrometry and to correlate the identified proteins with clinical features. METHODOLOGY: Twenty patients with radiographic evidence of apical periodontitis and need for root canal re-treatment were selected. Samples from the root canal contents were collected and processed using two-dimensional capillary nano-flow liquid chromatography and electrospray ionization tandem mass spectrometry. The acquired spectra were separately searched against specific protein database. The results obtained were analysed using descriptive statistics. Additionally, Pearson's chi-square test or one sided Fisher's exact test, as appropriate, was chosen to examine the null hypothesis that there is no relationship between each clinical feature and the presence of specific microbial or human proteins. Significance levels were set at 5% (P < 0.05). RESULTS: A total of 1153 human and 720 microbial UniProt accession numbers corresponding to proteins were recovered. The greater prevalence of proteins was related to biological functions, such as cellular and metabolic processes. A considerable number of microbial proteins with clinical relevance functions, such as pathogenesis/virulence, proteolysis, cell adhesion and drug resistance, were detected. Common endodontic pathogens related to post-treatment endodontic disease such as Enterococcus spp., Propionibacterium spp. and Streptococcus spp. were associated with 23, 40 and 94 distinct proteins, respectively. As for human proteins, many factors related to the immune system process were detected. No significant correlations were found between microbial and human proteins and the clinical features investigated (P > 0.05). CONCLUSIONS: A considerable number of microbial and human proteins were identified using proteomic analyses, being mainly related to processes indicating cell viability. No significant correlation was found between proteins and clinical features. These findings suggest a network of important microbial pathogenic functions that may be responsible for the host immune system response. PMID- 30284722 TI - Association of LTA gene haploblock with periodontal disease in Italian adults. AB - BACKGROUND: Periodontitis is a common oral disease caused by host inflammatory response towards bacteria biofilm. The chronic activation of immune response leads to destruction of teeth supporting tissue, bone loss and tooth detachment. Different factors could be involved in the development and severity of the disease; among them the host genetic background should be considered. OBJECTIVES: In our study, we analysed haploblocks in a genomic region within major histocompatibility complex (MHC) locus aimed at disclosing a possible correlation with the risk of periodontal disease in 602 adult subjects from North-East Italy. RESULTS: The CTTAC haploblock (formed by LTA-rs2857709, LTA-rs2844484, LTA- rs2229094, LTA-rs2229092 and LTA-rs1041981 polymorphisms) correlated with protection towards periodontitis condition, after regression analysis including age and smoking status as covariates (P-value = 0.015). CONCLUSION: Our results suggest that a haplotype within LTA gene (encoding for lymphotoxin alpha) is involved in the susceptibility towards chronic periodontitis. PMID- 30284723 TI - Effect of client complaints on small animal veterinary internists. AB - OBJECTIVES: To investigate the effect of client complaints on small animal veterinary internists' welfare, job satisfaction and medical practices. MATERIALS AND METHODS: Cross-sectional anonymous survey study. Between February 1 and March 31, 2017, a web-based questionnaire was made available through the American College Veterinary Internal Medicine sub-specialty Small Animal Internal Medicine E-mail List Serve. RESULTS: A total of 92 completed surveys were available for review. Fifty-nine (64?1%) respondents received a client complaint during the previous 6 months with cost of care the most common reason (53?3%). Eighty-nine (96?7%) respondents worry about client complaints being made against them with 33 (35?8%) stating they worry "most of the time" or "all of the time." Thirty-two (34?8%) reported being verbally assaulted by a client in the previous 6 months and 27 (29?4%) reported being threatened with litigation during the previous 6 months. Sixty-six (71?7%) have reported changing the way they practice medicine to avoid a client complaint and 40 (43?5%) have considered changing their career because of complaints made against them. CLINICAL RELEVANCE: Client complaints are a frequent problem among small animal veterinary internists that have detrimental effects on job satisfaction, psychological distress and medical practices. PMID- 30284724 TI - Low protein diets for non-diabetic adults with chronic kidney disease. AB - BACKGROUND: Chronic kidney disease (CKD) is defined as reduced function of the kidneys present for 3 months or longer with adverse implications for health and survival. For several decades low protein diets have been proposed for participants with CKD with the aim of slowing the progression to end-stage kidney disease (ESKD) and delaying the onset of renal replacement therapy. However the relative benefits and harms of dietary protein restriction for preventing progression of CKD have not been resolved. This is an update of a systematic review first published in 2000 and updated in 2006 and 2009. OBJECTIVES: To determine the efficacy of low protein diets in preventing the natural progression of CKD towards ESKD and in delaying the need for commencing dialysis treatment in non-diabetic adults. SEARCH METHODS: We searched the Cochrane Kidney and Transplant Register of Studies up to 2 March 2018 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. SELECTION CRITERIA: We included randomised controlled trials (RCTs) or quasi RCTs in which adults with non-diabetic chronic kidney disease (stages 3 to 5) not on dialysis were randomised to receive a very low protein intake (0.3 to 0.4 g/kg/d) compared with a low protein intake (0.5 to 0.6 g/kg/d) or a low protein intake compared with a normal protein intake (>= 0.8 g/kg/d) for 12 months or more. DATA COLLECTION AND ANALYSIS: Two authors independently selected studies and extracted data. For dichotomous outcomes (death, all causes), requirement for dialysis, adverse effects) the risk ratios (RR) with 95% confidence intervals (CI) were calculated and summary statistics estimated using the random effects model. Where continuous scales of measurement were used (glomerular filtration rate (GFR), weight), these data were analysed as the mean difference (MD) or standardised mean difference (SMD) if different scales had been used. The certainty of the evidence was assessed using GRADE. MAIN RESULTS: We identified an additional six studies to include 17 studies with 2996 analysed participants (range 19 to 840). Four larger multicentre studies were subdivided according to interventions so that the review included 21 separate data sets. Mean duration of participant follow-up ranged from 12 to 50 months.Random sequence generation and allocation concealment were considered at low risk of bias in eleven and nine studies respectively. All studies were considered at high risk for performance bias as they were open-label studies. We assessed detection bias for outcome assessment for GFR and ESKD separately. As GFR measurement was a laboratory outcome all studies were assessed at low risk of detection bias. For ESKD, nine studies were at low risk of detection bias as the need to commence dialysis was determined by personnel independent of the study investigators. Five studies were assessed at high risk of attrition bias with eleven studies at low risk. Ten studies were at high risk for reporting bias as they did not include data which could be included in a meta-analysis. Eight studies reported funding from government bodies while the remainder did not report on funding.Ten studies compared a low protein diet with a normal protein diet in participants with CKD categories 3a and b (9 studies) or 4 (one study). There was probably little or no difference in the numbers of participants who died (5 studies 1680 participants: RR 0.77, 95% CI 0.51 to 1.18; 13 fewer deaths per 1000; moderate certainty evidence). A low protein diet may make little or no difference in the number of participants who reached ESKD compared with a normal protein diet (6 studies, 1814 participants: RR 1.05, 95% CI 0.73 to 1.53; 7 more per 1000 reached ESKD; low certainty evidence). It remains uncertain whether a low protein diet compared with a normal protein intake impacts on the outcome of final or change in GFR (8 studies, 1680 participants: SMD -0.18, 95% CI -0.75 to 0.38; very low certainty evidence).Eight studies compared a very low protein diet with a low protein diet and two studies compared a very low protein diet with a normal protein diet. A very low protein intake compared with a low protein intake probably made little or no difference to death (6 studies, 681 participants: RR 1.26, 95% CI 0.62 to 2.54; 10 more deaths per 1000; moderate certainty evidence). However it probably reduces the number who reach ESKD (10 studies, 1010 participants: RR 0.65, 95% CI 0.49 to 0.85; 165 per 1000 fewer reached ESKD; moderate certainty evidence). It remains uncertain whether a very low protein diet compared with a low or normal protein intake influences the final or change in GFR (6 studies, 456 participants: SMD 0.12, 95% CI -0.27 to 0.52; very low certainty evidence).Final body weight was reported in only three studies. It is uncertain whether the intervention alters final body weight (3 studies, 89 participants: MD -0.40 kg, 95% CI -6.33 to 5.52; very low certainty evidence).Twelve studies reported no evidence of protein energy wasting (malnutrition) in their study participants while three studies reported small numbers of participants in each group with protein energy wasting. Most studies reported that adherence to diet was satisfactory. Quality of life was not formally assessed in any studies. AUTHORS' CONCLUSIONS: This review found that very low protein diets probably reduce the number of people with CKD 4 or 5, who progress to ESKD. In contrast low protein diets may make little difference to the number of people who progress to ESKD. Low or very low protein diets probably do not influence death. However there are limited data on adverse effects such as weight differences and protein energy wasting. There are no data on whether quality of life is impacted by difficulties in adhering to protein restriction. Studies evaluating the adverse effects and the impact on quality of life of dietary protein restriction are required before these dietary approaches can be recommended for widespread use. PMID- 30284725 TI - His bundle pacing: Still much to learn. PMID- 30284726 TI - Autoimmune heparin-induced thrombocytopenia of delayed onset: a clinical challenge. AB - BACKGROUND: Heparin-induced thrombocytopenia (HIT) usually appears at 5 to 10 days after initiation of heparin. Autoimmune HIT can arise after discontinuation of heparin treatment (delayed-onset HIT) or without any preceding heparin exposure (spontaneous HIT syndrome). CASE REPORT: This case presents a course of autoimmune HIT with delayed onset. The patient was hospitalized due to influenza pneumonia and received low-molecular-weight heparin thromboprophylaxis for 9 days. Seven days after discharge, she was readmitted because of a cerebral sinus vein thrombosis and severe thrombocytopenia. Intracranial bleeding and brain infarction caused her death. DISCUSSION: Autoimmune HIT was confirmed by functional heparin-induced platelet (PLT) activation test. Intracranial bleeding prevented continuous and effective anticoagulation. PLT transfusions were given, although they are generally advised against in HIT patients due to potential risk of thromboembolic events. CONCLUSION: This case presents that testing PLT activating antibodies both in the presence and in the absence of current heparin treatment helps to diagnose patients with autoimmune HIT. There is conflicting evidence to refuse PLT transfusion when HIT is complicated with life-threatening bleeding. PMID- 30284727 TI - Multicenter reproducibility of quantitative susceptibility mapping in a gadolinium phantom using MEDI+0 automatic zero referencing. AB - PURPOSE: To determine the reproducibility of quantitative susceptibility mapping at multiple sites on clinical and preclinical scanners (1.5 T, 3 T, 7 T, and 9.4 T) from different vendors (Siemens, GE, Philips, and Bruker) for standardization of multicenter studies. METHODS: Seven phantoms distributed from the core site, each containing 5 compartments with gadolinium solutions with fixed concentrations between 0.625 mM and 10 mM. Multi-echo gradient echo scans were performed at 1.5 T, 3 T, 7 T, and 9.4 T on 12 clinical and 3 preclinical scanners. DICOM images from the scans were processed into quantitative susceptibility maps using the Laplacian boundary value (LBV) and MEDI+0 automatic uniform reference algorithm. Region of interest (ROI) analyses were performed by a physicist to determine agreement between results from all sites. Measurement reproducibility was assessed using regression, Bland-Altman plots, and the intra class correlation coefficient (ICC). RESULTS: Quantitative susceptibility mapping (QSM) from all scanners had similar, artifact-free visual appearance. Regression analysis showed a linear relationship between gadolinium concentrations and average QSM measurements for all phantoms (y = 350x - 0.0346, r2 >0.99). The SD of measurements increased almost linearly from 32 ppb to 230 ppb as the measured susceptibility increased from 0.26 ppm to 3.56 ppm. A Bland-Altman plot showed the bias, upper, and lower limits of agreement for all comparisons were -10, 210, and 200 ppb, respectively. The ICC was 0.991 with a 95% CI (0.973, 0.99). CONCLUSIONS: QSM shows excellent multicenter reproducibility for a large range of susceptibility values encountered in cranial and extra-cranial applications on a diverse set of scanner platforms.

PMID- 30284728 TI - Characteristics of non-melanoma skin cancers of the cutaneous perioral and vermilion lip treated by Mohs micrographic surgery. AB - BACKGROUND: The lip and surrounding perioral region are susceptible to non melanoma skin cancer, but the distribution of basal cell and squamous cell carcinoma on the cutaneous and vermilion lips has not been fully elucidated. OBJECTIVE: To investigate the distribution of cutaneous and vermilion lip non melanoma skin cancer and to better describe risk factors, anatomic location, treatment characteristics and oncologic outcomes. METHODS: A retrospective comparative case series of patients undergoing Mohs micrographic surgery (MMS) at a single academic centre for lip and perioral basal cell and squamous cell carcinoma was performed over a 5-year period. Demographics, medical comorbidities, surgical characteristics and recurrence status were extracted. RESULTS: Forty-five vermilion and 116 cutaneous lip cancers were identified. Basal cell carcinoma (BCC) was more common in the cutaneous perioral region, while squamous cell carcinoma (SCC) was more common on the vermilion lip (P < 0.001). BCCs were more common on the upper vermilion lip and SCCs were more common on the lower vermilion lip (P < 0.001). Within the cutaneous perioral region, both BCCs and SCCs were more common on the upper perioral surface (P = 0.002). Male gender was associated with lower lip SCC (P = 0.015). Smoking, immunosuppression, anticoagulant use and hydrochlorothiazide use were not associated with cancer type or location. Recurrences were rare, but more common in vermilion lip cancers (6.6%) compared to perioral cutaneous cancers (0.8%). Outcomes for all groups were similar; BCCs of the vermilion lip had significantly greater mean MMS stages (P < 0.001) as did SCCs (P = 0.05). CONCLUSION: Basal cell carcinoma is more commonly encountered on the cutaneous lip, whereas SCC is more common on the vermilion lip. Within the vermilion lip, BCC favours the upper lip, while SCC favours the lower lip. Within the cutaneous perioral region, both BCC and SCC favour the upper cutaneous tissue. Early stage lip cancers are curable by Mohs micrographic surgery with rare recurrences. PMID- 30284730 TI - Dynamic per slice Shimming for Simultaneous Brain and Spinal Cord fMRI. AB - PURPOSE: Simultaneous brain and spinal cord functional MRI is emerging as a new tool to study the central nervous system but is challenging. Poor B0 homogeneity and small size of the spinal cord are principal obstacles to this nascent technology. Here we extend a dynamic shimming approach, first posed by Finsterbusch, by shimming per slice for both the brain and spinal cord. METHODS: We shim dynamically by a simple and fast optimization of linear field gradients and frequency offset separately for each slice in order to minimize off-resonance for both the brain and spinal cord. Simultaneous acquisition of brain and spinal cord fMRI is achieved with high spatial resolution in the spinal cord by means of an echo-planar RF pulse for reduced FOV. Brain slice acquisition is full FOV. RESULTS: T2*-weighted images of brain and spinal cord are acquired with high clarity and minimal observable image artifacts. Fist-clenching fMRI experiments reveal task-consistent activation in motor cortices, cerebellum, and C6-T1 spinal segments. CONCLUSIONS: High quality functional results are obtained for a sensory motor task. Consistent activation in both the brain and spinal cord is observed at individual levels, not only at group level. Because reduced FOV excitation is applicable to any spinal cord section, future continuation of these methods holds great potential. PMID- 30284731 TI - Micronuclei frequency in urothelial cells of bladder cancer patients, as a biomarker of prognosis. AB - It has been suggested that the frequency of micronuclei (MN) in defoliated urothelial cells could be used as a biomarker for both the potential risk of bladder cancer (BC) and its progression. To prove this we have carried out a large study evaluating the MN frequency in a group of 383 hospital patients submitted to cystoscopy. From them, 77 were negative in their first cystoscopy, and were considered as a reference group; 79 were positive and were classified as patients with tumor; and 227 with previous bladder cancer submitted to follow-up monitoring were negative and classified as BC patients without tumor. Vesical washes were processed and the obtained cells were placed onto microscope slides for further scoring. To minimize scoring misinterpretations, cells were stained with DAPI, and observed in a fluorescence microscope. Results indicated that patients with BC presented higher incidence of MN than controls (18.29 +/- 10.04 vs. 14.40 +/- 8.49, P = 0.010, respectively). When individuals with BC were classified depending on whether the BC was a primary or a recidivated tumor, those patients with recurrent BC presented a higher frequency of MN than those where BC was detected for the first time (19.22 +/- 9.59 vs. 16.60 +/- 10.78, respectively); nevertheless, this increase did not reach statistical significance. Finally, a positive and significant correlation was observed between MN frequency and the degree of the tumor (P = 0.038). All this together would confirm the potentiality of the MN frequency in urothelial defoliated cells assay to be used, at least, in the follow-up and surveillance of BC patients. Environ. Mol.

PMID- 30284732 TI - Thrombotic thrombocytopenic purpura relapse induced by acute hepatitis E transmitted by cryosupernatant plasma and successfully controlled with ribavirin. AB - BACKGROUND: Hepatitis E virus (HEV) can be transmitted by transfusion of any type of blood component, but there are few data on the potential risk of transmitting this virus and the associated complications. We provide evidence that HEV can be transmitted by cryosupernatant plasma, and that HEV infection can act as a trigger for thrombotic thrombocytopenic purpura (TTP). STUDY DESIGN AND METHODS: A patient with a history of TTP treated with plasmapheresis 2 months previously developed jaundice and a TTP exacerbation with purpura, thrombocytopenia, schistocytes, and undetectable ADAMTS-13 activity. He was diagnosed with acute hepatitis E and treated with ribavirin. TTP remitted with remission of HEV infection. RESULTS: Traceback to determine the source of the infection showed that 1 cryosupernatant plasma among the 99 different blood components used for the patient's last plasmapheresis was positive for HEV RNA, with an estimated viral load of 5000 to 10,000 IU/mL. Phylogenetic analysis proved the transfusion transmitted route of acute hepatitis E. CONCLUSION: In a patient with TTP, acute HEV infection transmitted by cryosupernatant plasma may trigger exacerbation of TTP, which can be controlled on remission of HEV infection with ribavirin. PMID- 30284733 TI - Legs of male fiddler crabs evolved to compensate for claw exaggeration and enhance claw functionality during waving displays. AB - Many exaggerated morphological traits evolve under sexual selection. However, the optimal level of exaggeration is dictated by a trade-off between natural and sexual selection, representing a balance between its benefits and associated costs. Male fiddler crabs wave an enlarged major claw during behavioural displays that eliminates the need for direct combat, and determines courtship outcomes. The outcomes of these displays often depend on claw size, exposing males to selection for larger claws to improve mating and combat success. Applying phylogenetic comparative methods to 27 fiddler crab species, we examined the evolution of major claw morphologies, leg morphologies, and waving displays to determine whether these traits coevolved to optimise functioning of the exaggerated claw, or to mitigate potential metabolic or locomotor costs. We found legs to be sexually dimorphic, with males having longer legs than females. Legs were also longer in species that waved laterally rather than vertically, in species with larger major claws, and in species whose major claws were relatively elongate. These results suggest that leg morphology has coevolved with claw enlargement to enhance functionality of the major claw during waving displays, in addition to compensating for any negative effects of claw size.

PMID- 30284735 TI - Nonhormonal selective estrogen receptor modulator 1-(2-[4-{(3R,4S)-7-Methoxy-2, 2 dimethyl-3-phenyl-chroman-4yl}phenoxy]ethyl)pyrrolidine hydrochloride (ormeloxifene hydrochloride) for the treatment of breast cancer. AB - Breast cancer is the most common type of diagnosed cancers in women, difficult to treat, and has received international attention because of its aggressive nature and inherent drug resistance mechanisms. Development of a better selective estrogen receptor modulator with good therapeutic profile and less toxicity is very crucial in this scenario. This study was undertaken to evaluate and compare the in vitro and in vivo antitumor activities of ormeloxifene with other clinically used breast cancer drugs. Cytotoxic activity of ormeloxifene was compared with standard drugs, 4-hydroxytamoxifene and Adriamycin. Ormeloxifene (50 MUM) concentration showed cytotoxicity of 75% and 82% in MDAMB-231 and 24% and 80% in MCF-7 cells, respectively, after 72 and 144 hr of incubation as displayed by cell viability assay. The same concentration of ormeloxifene was shown to exert 74% caspase-7 activation in MCF-7 cells after 24 hr of incubation by fluorescence resonance energy transfer assay. Cell cycle analysis proved that there was an increase in sub-G1 peak to 64.4% and 33.9% in MDAMB-231 and MCF-7 cells, respectively, after treatment using ormeloxifene (50 MUM) for 48 hr. The nonobese diabetic-severe combined immunodeficiency mice bearing tumor xenografts of triple negative MDAMB-231 cells treated with ormeloxifene (3 mg/kg bw) showed significant regression in relative tumor volume compared to control. From the results obtained and as evidenced from prior literature, ormeloxifene in addition to contraceptive use, can be repositioned for the development of an efficacious anticancer drug. These data present the preclinical part of a well concerted effort to place ormeloxifene into further clinical trials.

AB - Preclinical Research & Development Withanolide A (WA), a steroidal lactone is a major bioactive constituent of Withania somnifera (L.) with remarkable neuropharmacological activity. In this study, we investigated the permeability, plasma protein binding (PPB), blood partitioning, intravenous (i.v.), and oral pharmacokinetics as well as i.v. tissue distribution (TD) of pure WA in a rat model. The PPB, RBCs partitioning, and permeability of WA were determined by Ultra Performance Liquid Chromatography (UPLC) method. However, the pharmacokinetics and TD of WA were evaluated by validated and sensitive liquid chromatography coupled mass spectrometry (LC-ESI-MS/MS) method. The PPB and permeability of WA were determined by equilibrium dialysis and parallel artificial membrane permeability assay method, respectively. The results demonstrated that WA has high PPB and passive permeability. Furthermore, WA was found to have fast equilibration between RBCs and plasma. Following i.v. (2 mg/kg) and per-oral (25 mg/kg) administration of WA, the max concentration (Cmax ) in plasma was found as 85.53 +/- 6.54 and 48.04 +/-5.78 ng/mL, respectively. The TD study results indicated that WA has a rapid and wide TD. The maximum concentration in various tissues was found in following order: Clung > Cliver > Ckidney ~ Cspleen > Cheart > Cbrain . The preclinical in vitro, as well as pharmacokinetics and TD results, are anticipated to support the future preclinical and clinical application of WA. PMID- 30284739 TI - Investigation of the antimicrobial and anticancer activity of aminonaphthoquinones. AB - In this study, we report on the inhibitory activity of synthesized aminonaphthoquinones against two bacterial and one fungal species to determine their antimicrobial properties. A minimum inhibitory concentration (MIC) of 7.8 MUg/mL was obtained against the fungus, Candida albicans, which was better than that of Amphotericin B (MIC = 31.25 MUg/mL). Escherichia coli (Gram -), was inhibited at a MIC of 23.4 MUg/mL and Staphylococcus aureus (Gram +) at a MIC of 31.3 MUg/mL. The aminonaphthoquinones were also screened against HCT116 colon, PC3 prostate and HepG2 liver cancer cell lines to evaluate their cytostatic effects. They had potent activity (GI50 = 5.87-9.90 MUM) which was about three-6 fold better than that of parthenolide (GI50 = 25.97 MUM) against the prostate cancer cell line. These compounds were generally more selective for cancer cells than for normal human lung fetal fibroblasts (WI-38). Hit, Lead & Candidate Discovery.

AB - BACKGROUND AND OBJECTIVE: Although previous studies revealed the potential use of probiotics in the control of periodontitis, little is known about their interactions with gingival epithelial cells (GECs). Since GECs comprise the first defense in the subgingival microenvironment, the aim of this study was to evaluate the effect of probiotic lactobacilli and bifidobacteria strains on OBA-9 cells challenged with Porphyromonas gingivalis. METHODS: Immortalized human GECs (OBA-9) were challenged with live P. gingivalis (strains W83 and ATCC33277) and co-infected with one of 12 tested probiotic strains at a multiplicity of infection (MOI) of 1:1000 for 2 hours. Bacterial adhesion and invasion were determined by antibiotic exclusion analysis and CFU counting. OBA-9 viability was assessed by MTT assay, and levels of inflammatory mediators (TNF-alpha, IL-1beta, and CXCL8) in the supernatants were determined by ELISA. The expression of genes encoding Toll-like receptors (TLR2, TLR4) was evaluated by RT-qPCR. RESULTS: Both strains of P. gingivalis were able to adhere and invade OBA-9 cells, with significant loss in cell viability, increase in the levels of TNF-alpha and IL 1beta, and upregulation of TLR4. However, co-infection with probiotics attenuated these effects in P. gingivalis challenged GECs. Most probiotics maintained OBA-9 viability and reduced pathogens adhesion and invasion. Furthermore, probiotics were able to adhere to GECs, which was enhanced for most strains in the presence of P. gingivalis. The synthesis of IL-1beta and TNF-alpha by P. gingivalis in challenged GECs was reduced in co-culture with most of the tested probiotics, whereas the secretion of CXCL8 increased, and TLR4 was downregulated. CONCLUSION: Probiotics can alter the interaction of GECs with P. gingivalis by modulating the pathogen's ability to adhere and invade these cells, as well as by regulating the innate immune response. Such properties are strain-specific and may indicate the most efficient probiotics to control periodontitis. PMID- 30284742 TI - A genome-wide association study identifies an association between variants in EFCAB4B gene and periodontal disease in an Italian isolated population. AB - BACKGROUND AND OBJECTIVE: Periodontitis in one of the most prevalent dental diseases. Despite numerous studies have investigated its aetiopathogenetic factors, few works have focused on its genetic predisposition and most of them took into account only candidate genes. Therefore, we conducted a Genome Wide Association Study in an Italian isolated population aimed at uncovering genetic variants that predispose to this disorder. METHODS: Diagnosis of chronic periodontitis was made following the criteria of the American Academy of Periodontology. Patients with chronic periodontitis were grouped into different categories: slight, severe, localized and generalized. A control group composed by people without signs of periodontitis or gingivitis was defined. DNA was genotyped using 370k Illumina chips. Linear mixed model regression was used to test the association between each single nucleotide polymorphism (SNP) (independent variable) and the periodontitis status (dependent variable), controlling for confounders sex, age and smoking. The genomic kinship matrix was also used as random effect. RESULTS: Four SNPs on the gene EFCAB4B resulted significantly associated to localized periodontitis (P < 5 * 10-8 ), with the best hit on the rs242016 SNP (P = 1.5 * 10-8 ). CONCLUSION: We have identified a novel significant association between the EFCAB4B gene and localized periodontitis. These results open a new perspective in the understanding of genetic factors contributing to this common disorder. PMID- 30284743 TI - [CONGENITAL MALFORMATION: BILIARY ATRESIA]. AB - Congenital anomalies of biliary tract development are frequent causes of lingering course of physiologic jaundice which need timely verification of diagnosis followed by surgical treatment. Clinical observation of biliary atresia in a 10-month-old girl permits to accent pediatricians' attention to peculiarities of clinical picture, diagnosis and techniques for treatment of this pathology. PMID- 30284744 TI - RANZCOG Fellows' adherence to guidelines following cytological prediction of cervical adenocarcinoma-in-situ: Cause for concern? AB - BACKGROUND: For Australian women with screen-detected adenocarcinoma-in-situ (AIS), an excisional biopsy is mandatory for further assessment, treatment, and to exclude the presence of cervical adenocarcinoma. The only exclusion to this rule is if the woman has a clinically evident invasive cervical malignancy. Excisional treatments should be tailored according to a patient's age and future obstetric needs. To date, practitioner compliance with this recommendation has not been investigated. AIMS: To investigate clinical management for patients with a cytological test result predicting AIS. Secondary aims were to report the most severe histological findings of excisional biopsy specimens following cytological prediction of AIS and investigate treatment outcomes for conservatively managed patients with biopsy-confirmed AIS. MATERIALS AND METHODS: A retrospective, population-based cohort study was conducted. Cases were ascertained from the Tasmanian and Western Australia Cervical Screening Registries. Cytology and histology results for women with an index cervical smear reporting AIS from 2001 to 2012 were reviewed. RESULTS: Three hundred and twenty-one women (age range 18 69 years) had an index smear reporting AIS. Cervical cancer was diagnosed in 62 (19.3%) patients within the study cohort. Twenty-one of 321 patients (6.7%) were not initially managed according to the 2005 NHMRC Guidelines for the management of asymptomatic women with screen-detected abnormalities, including two women diagnosed with an occult cancer following a total hysterectomy. CONCLUSIONS: A minority of women were not managed in accordance with guidelines. This is of concern given that nearly one in five women with a smear predicting AIS had a final diagnosis of cervical cancer. PMID- 30284745 TI - A consensus opinion amongst stakeholders as to benefits of obstructive sleep apnoea treatment for cardiovascular health. AB - BACKGROUND AND OBJECTIVE: Obstructive sleep apnoea (OSA) is a prevalent sleep disorder associated with increased cardiovascular morbidity and mortality. Whether treatment of OSA improves cardiovascular risk remains controversial. Our aim was to determine a consensus opinion of key sleep medicine stakeholder groups as to the cardiovascular benefits of treating moderate-severe OSA. METHODS: A multidisciplinary panel was assembled from representatives from the Australasian Sleep Association, Sleep Health Foundation, Australasian Sleep Technologists Association, the Sleep Health Foundation Business Council and the Sleep Disorders Australia patient support group. Three statements reflecting areas of controversy related to cardiovascular benefits of OSA treatment were created. A modified RAND/UCLA appropriateness methodology was applied determining the panel's level of consensus and agreement with each statement. RESULTS: Voting results indicated the panel: (1) remained unsure whether moderate-severe OSA treatment improves rates of cardiovascular events/death, (2) agreed that moderate-severe OSA treatment improves blood pressure in patients with hypertension and (3) mostly agreed that moderate-severe OSA treatment improves left ventricular function in patients with heart failure. Consensus of opinion was achieved for statements (1) and (2), but was narrowly missed for statement (3). CONCLUSION: The panel believed that findings from large-scale randomized trials indicate that treatment of moderate-severe OSA has not been established to improve cardiovascular event or morbidity/mortality rates. Strong evidence supports the ability of treatment to reduce blood pressure. Whilst many panel members believed that treatment improves left ventricular function, some were uncertain of the clinical significance of this secondary endpoint measure derived from lesser quality evidence.

PMID- 30284747 TI - A generalized multistage approach to oral and nasal intubation in infants with Pierre Robin sequence: A retrospective review. AB - BACKGROUND: Airway management in children with Pierre Robin sequence in the infantile period can be challenging and frequently requires specialized approaches. AIMS: The aim of this study was to review our experience with a multistage approach to oral and nasal intubation in young infants with Pierre Robin sequence. METHODS: After IRB approval, we reviewed 13 infants with Pierre Robin sequence who underwent a multistage approach to intubation in the operating room for mandibular distractor or gastrostomy tube placement. All patients underwent awake placement of either an LMA-ClassicTM #1 or ProSealTM laryngeal mask airway size #1. General anesthesia was induced with sevoflurane, and patients were relaxed with rocuronium. The laryngeal mask airway was replaced with an air-Q(r) 1.0. Children were then intubated through the air-Q(r) 1.0 using a flexible fiberoptic bronchoscope. In cases that required a nasotracheal tube, the oral tube was left in place while a flexible fiberoptic bronchoscope loaded with a similar internal diameter nasal Ring-Adair-Elwyn (RAE) tube was introduced into the nares. Once the scope was in proximity to the glottis, the oral tube was removed and the patient was intubated with the nasal RAE over the fiberscope. RESULTS: All 13 patients with Pierre Robin sequence were successfully intubated. We observed no periods of desaturation during placement and induction with the LMA-ClassicTM or ProSealTM laryngeal mask airway except in one patient who was in extremis in the neonatal intensive care unit and required emergent transport to the operating room with the laryngeal mask airway in place. We observed several brief periods of desaturation during the apneas associated with fiberoptic intubation. CONCLUSION: In conclusion, we were able to use a ventilation-driven, multistaged approach using the unique properties of different supraglottic airways to facilitate oral and nasal intubation in 13 infants with Pierre Robin sequence. PMID- 30284748 TI - Virtual reality for lumbar puncture in a morbidly obese patient with leukemia. AB - Virtual reality is an immersive technology that can provide distraction and anxiolysis during painful procedures. While it has been shown to be effective in less invasive procedures, it is underutilized in more invasive procedures. We describe using virtual reality for a morbidly obese patient with leukemia undergoing lumbar puncture. The use of virtual reality reduced the amount of analgesics and anxiolytics and the procedure and recovery times compared with no virtual reality. PMID- 30284749 TI - Dental hypomineralization treatment: A systematic review. AB - INTRODUCTION: Defects in the maturation stage of amelogenesis result in a normal volume of enamel but insufficient mineralization, called hypomineralization. Molar-incisor hypomineralization (MIH), amelogenesis imperfecta and dental fluorosis (DF) are examples of such defects. OBJECTIVE: To evaluate the effectiveness of the treatments applied to the different forms of dental hypomineralization. MATERIALS AND METHODS: PubMed, Scopus, Cochrane Library, Web of Science, and Embase were screened. The research was limited to studies published in English, Spanish, and Portuguese, until May 30, 2018. The research question was formulated following the Population, Intervention, Comparison, Outcome strategy. The quality of the methodology of each article was evaluated employing the Cochrane Handbook for Systematic Reviews. RESULTS: From the initial research, 7895 references were obtained, of which 33 were included in the systematic review. The following treatments were reported: desensitizing and remineralizing products, resin infiltration, restorations, fissure sealants, tooth bleaching, enamel microabrasion and calcium, and vitamins supplements. CONCLUSIONS: Although the results are suggestive, there is a clear need for a greater uniformity of the methodologies, thus allowing for the development of clinical guidelines. Nevertheless, it was possible to identify several effective treatments for teeth with MIH (arginine pastes or fluoride varnishes) and DF (tooth bleaching and/or enamel microabrasion). CLINICAL SIGNIFICANCE: Because MIH, amelogenesis imperfecta, and DF are commonly seen in dental daily practice, it is extremely important to analyze the literature regarding its treatment. PMID- 30284750 TI - Symmetrical acral keratoderma revisited: proposal for a new term, 'pigmented carpotarsal hyperkeratosis'. AB - First reported from Taiwan mistakenly as acral acanthosis nigricans in 1991, pigmented carpotarsal hyperkeratosis or hyperkeratosis nigricans carpi et tarsi displays a peculiar distribution of velvety brown-grey hyperpigmented plaques symmetrically on the flexural side of the wrists and ankles and on the dorsal sides of the hands and feet. A marked epidermal hyperkeratosis with typically mild acanthosis and papillomatosis is observed in histology. Whitish maceration upon perspiration or water exposure, with exacerbation in summer but remission in winter, is common. The association with obesity, endocrine disorders, atopic dermatitis, ichthyosis or malignancy is unknown. Familial occurrence and hereditary patterns are ill-defined. There is preliminary evidence indicating a pathogenic role of missense mutation in the transcription factor 4 gene. Treatment is empirical, with good outcome with topical retinoids and keratolytic agents. Recurrence is common, and long-term prognosis is unclear. To be distinguished are acral acanthosis nigricans, palmoplantar keratoderma of the Nagashima type, palmoplantar keratoderma of the Bothnian type and aquagenic palmoplantar keratoderma. Most reported cases are from Southern China and are predominantly observed in men between the ages of 20 and 40 years. The currently used term 'symmetrical acral keratoderma' is non-specific and misleading and may lead to global unawareness, underreporting or misdiagnosis of this phenomenon. Further genetic and molecular studies are required to clarify its pathogenesis and relation to palmoplantar keratoderma. PMID- 30284751 TI - Using DNA methylation to validate an electronic medical record phenotype for smoking. AB - A validated, scalable approach to characterizing (phenotyping) smoking status is needed to facilitate genetic discovery. Using established DNA methylation sites from blood samples as a criterion standard for smoking behavior, we compare three candidate electronic medical record (EMR) smoking metrics based on longitudinal EMR text notes. With data from the Veterans Aging Cohort Study (VACS), we employed a validated algorithm to translate each smoking-related text note into current, past or never categories. We compared three alternative summary characterizations of smoking: most recent, modal and trajectories using descriptive statistics and Spearman's correlation coefficients. Logistic regression and area under the curve analyses were used to compare the associations of these phenotypes with the DNA methylation sites, cg05575921 and cg03636183, which are known to have strong associations with current smoking. DNA methylation data were available from the VACS Biomarker Cohort (VACS-BC), a sub study of VACS. We also considered whether the associations differed by the certainty of trajectory group assignment (<0.80/>=0.80). Among 140 152 VACS participants, EMR summary smoking phenotypes varied in frequency by the metric chosen: current from 33 to 53 percent; past from 16 to 24 percent and never from 24 to 33 percent. The association between the EMR smoking pairs was highest for modal and trajectories (rho = 0.89). Among 728 individuals in the VACS-BC, both DNA methylation sites were associated with all three EMR summary metrics (p < 0.001), but the strongest association with both methylation sites was observed for trajectories (p < 0.001). Longitudinal EMR smoking data support using a summary phenotype, the validity of which is enhanced when data are integrated into statistical trajectories. PMID- 30284752 TI - Biomimetic Syntheses of (+/-)-Isopalhinine A, (+/-)-Palhinine A, and (+/-) Palhinine D. AB - The first total synthesis of isopalhinine A, as well as unified syntheses of palhinine A and palhinine D, were successfully accomplished by means of a biomimetic strategy that proceeds through a bioinspired 5/6/6/9 tetracyclic intermediate, which mimics the amino ketone form of palhinine D. An early-stage direct SN 2 cyclization to construct the nine-membered azonane ring minimized the transannular strain that would otherwise be increased by the twisted nature of the isotwistane skeleton. Then, a diastereoselective Diels-Alder reaction of a masked ortho-benzoquinone using the nine-membered ring as a steric shielding group furnished a functionalized 6/6/9 tricyclic skeleton and established the desired stereochemistry at the C3, C7, C12, and C15 positions in one step. A thiol-mediated acyl radical cyclization gave the bioinspired intermediate bearing three differentiated oxygen-containing functional groups, from which all three total syntheses could be completed in either two or three additional steps.

AB - OBJECTIVE: To compare color change magnitude of an infiltrative resin and a flowable composite resin after immersion in commonly consumed beverages. MATERIALS AND METHODS: Disks (1 * 9 mm) of a flowable composite (Filtek Supreme Ultra Flowable) and a resin-infiltrative product (Icon) were made. Specimens were dark-stored in tap water (24 hours). Baseline color parameters (CIE L*a*b*) were obtained using a colorimeter (Easyshade V4, VITA). Specimens were immersed (dark stored, 37 degrees C, 1 week) in commercial beverages: Kool-Aid, coffee, Coca Cola, and tap water (control). DeltaE00 between final and baseline conditions for each material/beverage combination was determined (N = 10/group). Initial analysis of variance indicated significant impact of major factors/interactions on DeltaE00 . Subsequently, t-tests between DeltaE00 values of restorative materials within each beverage was performed: alpha 0.05. RESULTS: Kool-Aid produced the greatest color change for flowable composite, with a DeltaE00 significantly greater than the infiltrative product. No significant DeltaE00 differences were noted between products immersed in coffee, however color parameters causing these differences were not similar. Water or Coca-Cola immersion showed lowest DeltaE00 values for both materials, considered visually imperceptible: DeltaE00 values <0.8. CONCLUSIONS: Color change potential of infiltrative resin or resin composite was highly dependent on beverage type, with no general trends observed in which material was affected more. CLINICAL SIGNIFICANCE: Staining potential of an infiltrative restorative resin differs from that of a filled, flowable composite material on a beverage-by-beverage basis. The potential for color change seems not related to the presence or absence of fillers in the restorative material. PMID- 30284755 TI - Non-Val30Met mutation, septal hypertrophy, and cardiac denervation in patients with mutant transthyretin amyloidosis. AB - AIMS: Mutant transthyretin (ATTRm) amyloidosis is a systemic disease caused by the deposition of amyloid fibrils derived from mutated transthyretin. Although cardiac involvement impacts the prognosis of patients with ATTRm amyloidosis, the incidence of cardiac events, such as bradyarrhythmia, ventricular tachycardia, and heart failure, has not been fully elucidated. The aim of this study was to evaluate the prognosis and predictors of clinical outcomes, including cardiac events, in patients with ATTRm amyloidosis in Japan. METHODS AND RESULTS: We evaluated 90 consecutive patients with ATTRm amyloidosis at Kumamoto University. ATTRm amyloidosis was diagnosed by the observation of both amyloid fibril deposition on tissue biopsy and a transthyretin mutation on sequential analysis. Sympathetic nerve activity was evaluated in 59 patients using 123-iodine metaiodobenzylguanidine (123 I-MIBG) imaging. The endpoint was a composite of all cause death, hospitalization for heart failure, and implantation of a pacemaker, implantable cardioverter defibrillator, or cardiac resynchronization therapy defibrillator. Sixty-seven patients had the Val30Met mutation (74%). The composite endpoint occurred in 23 patients (26%): all-cause death (n = 6), hospitalization for worsening heart failure (n = 1), and implantation of an implantable cardioverter defibrillator (n = 6), cardiac resynchronization therapy defibrillator (n = 3), or pacemaker (n = 7). The 5-year incident rate for clinical outcomes was 19%. In a multivariate Cox hazard analysis, age [hazard ratio (HR): 1.07, 95% confidence interval (95% CI): 1.01-1.12, P = 0.015], PQ interval (HR: 1.01, 95% CI: 1.00-1.02, P = 0.042), interventricular septum thickness in diastole (HR: 1.25, 95% CI: 1.09-1.42, P = 0.001), and non-Val30Met mutation (HR: 4.31, 95% CI: 1.53-12.16, P = 0.006) were independent predictive factors of clinical outcomes. Kaplan-Meier analysis demonstrated a significantly higher probability of the composite endpoint in the non-Val30Met group than in the Val30Met group (log-rank test: P = 0.002) and in patients with left ventricular hypertrophy than in patients without left ventricular hypertrophy (log-rank test: P < 0.001). In patients who underwent 123 I-MIBG imaging, a delayed heart-to-mediastinum (HM) ratio <1.6 was a significant predictive factor of the composite endpoint (HR: 4.98, 95% CI: 1.73-14.37, P = 0.003) in the univariate Cox hazard analyses. Kaplan-Meier curve analysis showed that a delayed HM ratio <1.6 was associated with a poor prognosis (log-rank test: P = 0.001). CONCLUSIONS: Non-Val30Met mutation, septal hypertrophy, and a delayed HM ratio are useful predictors of clinical outcomes in patients with ATTRm amyloidosis in Japan. These results suggest that it is important to evaluate cardiac involvement in terms of morphological (left ventricular hypertrophy) and functional (cardiac denervation) perspectives using echocardiography and 123 I-MIBG imaging, respectively. PMID- 30284756 TI - Ni-Catalyzed alpha-Alkylation of Unactivated Amides and Esters with Alcohols by Hydrogen Auto-Transfer Strategy. AB - A transition-metal-catalyzed borrowing hydrogen/hydrogen auto-transfer strategy allows the utilization of feedstock alcohols as an alkylating partner, which avoids the formation of stoichiometric salt waste and enables a direct and benign approach for the construction of C-N and C-C bonds. In this study, a nickel catalyzed alpha-alkylation of unactivated amides and ester (tert-butyl acetate) is carried out by using primary alcohols under mild conditions. This C-C bond forming reaction is catalyzed by a new, molecularly defined nickel(II) NNN-pincer complex (0.1-1 mol %) and proceeds through hydrogen auto-transfer, thereby releasing water as the sole byproduct. In addition, N-alkylation of cyclic amides under Ni-catalytic conditions is demonstrated. PMID- 30284757 TI - Analysis of Entamoeba histolytica Membrane Proteome Using Three Extraction Methods. AB - Entamoeba histolytica membrane proteins are important players toward the pathogenesis of amoebiasis, but the roles of most of the proteins are not fully understood. Since efficient protein extraction method is crucial for a successful MS analysis, three extractions methods are evaluated for the use in studying the membrane proteome of E. histolytica: Two commercial kits (ProteoExtract from Calbiochem and ProteoPrep from Sigma), and a conventional laboratory method. The results show that ProteoExtract and the conventional method gave higher protein yields compared to ProteoPrep. LC-ESI-MS/MS identifies 456, 482, and 551 membrane fraction proteins extracted using ProteoExtract, ProteoPrep, and a conventional method, respectively. In silico analysis predicts 108 (21%), 235 (45%), and 177 (34%) membrane proteins from the extracts of ProteoExtract, ProteoPrep, and the conventional method, respectively. Furthermore, analysis of the cytosolic and membrane fractions shows the highest selectivity of the membrane proteins using the ProteoPrep extraction kit. Overall, this study reports 828 E. histolytica membrane fraction proteins that include 249 predicted membrane proteins. The data are available via ProteomeXchange with identifier PXD010171. PMID- 30284758 TI - A Supramolecular Palladium Catalyst Displaying Substrate Selectivity by Remote Control. AB - Inspired by enzymes, such as cytochrome P-450, the study of the reactivity of metalloporphyrins continues to attract major interest in homogeneous catalysis. However, little is known to take benefit from the substrate recognition properties of porphyrins containing additional, catalytically-relevant active sites. Herein, we introduce such approach using supramolecular ligands derived from metalloporphyrins customized with rigid, palladium-coordinating nitrile groups. According to different spectroscopic studies (NMR, UV-vis, X-ray diffraction, control experiments), the supramolecular ligands are able to accommodate pyridine derivatives as substrates inside the porphyrin pocket while the reactivity occurs in the peripheral side. By simply tuning a remote metal center, different binding events result in different catalyst reactivity: an enzyme-like feature leading to high levels of substrate selectivity when applied to representative palladium-catalyzed Suzuki-Miyaura reactions.

PMID- 30284761 TI - A retrospective cohort study of children with spinal muscular atrophy type 2 receiving anesthesia for intrathecal administration of nusinersen. AB - INTRODUCTION: Spinal muscular atrophy is characterized by loss of motor neurons in the anterior horn of the spinal cord with resultant proximal muscle weakness. Intrathecal nusinersen has revolutionized the treatment of spinal muscular atrophy. We reviewed the perioperative care of 61 anesthetics performed on eight patients with spinal muscular atrophy type 2 who received nusinersen over 30 months in conjunction with nusinersen's phase 3 clinical trials. METHODS: Anesthesia was induced in all patients with sevoflurane, nitrous oxide, and oxygen (30%) via facemask. A peripheral intravenous line was placed after the loss of consciousness in all but three procedures. General anesthesia was maintained in 58 anesthetics with a propofol infusion at 250-300 MUg/kg/min, while the remainder was maintained with inhalational anesthetics. The airway was managed via facemask or nasal cannula in all but two procedures, in whom a laryngeal mask airway was placed. We analyzed patient demographics, duration of anesthesia and of postanesthesia care unit stay, discharge destination, preprocedure oxygen saturation (SaO2 ), postanesthesia care unit discharge oxygen saturation, and occurrence of unanticipated admission or postdischarge hospitalization. RESULTS: Eight American Society of Anesthesiologists physical status three patients (3 male: 5 female) with a median age of 4.1 (2.1-7.8) years and median weight of 13.2 (10-24.7) kg, underwent 61 anesthetics for nusinersen administration or sham procedure. There were no intraoperative anesthetic complications of unanticipated cardiovascular instability, major neurologic events, respiratory failure, or death. Anesthesiologists performed 83% of the procedures. CONCLUSION: Nusinersen has revolutionized the care of patients with spinal muscular atrophy type 2 and anesthesiologists will be involved in its administration. We found that routine anesthetic care was safe and effective. PMID- 30284762 TI - Design, Synthesis and Molecular Docking Studies of some Tetrahydropyrimidine Derivatives as Possible Fascin Inhibitors. AB - Eight derivatives of tetrahydropyrimidine scaffold were designed and prepared as hybrid compounds possessing the structural features of both Monastrol as an anticancer drug and Nifedipine as a Fascin blocking agents. All of the compounds were evaluated for their cytotoxic potency and the ability to inhibit 4T1 breast cancer cells migration. Then they were investigated in silico for their ability to inhibit the Fascin protein using molecular docking simulation. The most potent and the weakest compounds according to the in vitro cytotoxicity assay were 4d and 4a with IC50 values of 193.70 and 248.75 umol, respectively. The least cytotoxic compound (4a) was one of the strongest ones in binding to the Fascin binding site according to molecular docking results. 4a and 4e inhibited the 4T1 cells migration better than other compounds. They were more potent than Nifedipine in inhibiting the migration process. In silico studies proved 4h as the most potent Fascin inhibitor in terms of DeltaGbind although it was not inhibiting migration. The controversy between the in vitro and in silico results may cancel the postulation of the involvement of the Fascin inhibition in the migration inhibition. However, the considerable anti-migratory effects of some of the synthesized compounds proved it reasonable to perform further in vivo experiments to introduce novel tumor metastasis inhibitors. PMID- 30284763 TI - Listening to the voice of patients with head and neck cancer: A systematic review and meta-synthesis. AB - The aim was to conduct a systematic review and a meta-synthesis of primary qualitative studies exploring experiences of head and neck cancer patients (HNC) undergoing radio and/or chemotherapy, in order to provide a better understanding of this phenomenon and supply new directions for care and clinical practice. Six databases were systematically searched, and 13 studies were included. The meta synthesis methodology was adopted to conceptualise the way in which patients lived their cancer journey and the impact of treatments on their daily life. Four themes embracing various aspects of HNC patients' experiences were identified: (a) self-body image and perceived quality of life; (b) experiences and treatment of symptoms; (c) cancer journey; and (d) the relationship with health professionals. The finding demonstrates the importance of acknowledging that treatment sequelae and patients' daily issues do not appear, develop and affect people's lives in isolation and should be considered and analysed as a whole within the social and cultural context of patients' lives. Further research is needed to explore the treatment experience of HNC patients throughout their cancer journey with a more holistic approach that involves health professionals, caregivers and other family members and peers in the community. PMID- 30284764 TI - One step up the ladder of prebiotic complexity: Formation of non-random linear polypeptides from binary systems of amino acids on silica. AB - We have evidenced the formation of linear oligopeptides with non-random sequences from mixtures of amino acids coadsorbed on silica and submitted to a simple thermal activation. The amino acid couples (Glutamic acid + Leucine) and (Aspartic acid + Valine) were deposited on a fumed silica and submitted to a single heating step at moderate temperature. The evolution of the systems was characterized by X-Ray Diffraction, InfraRed spectroscopy, Thermogravimetric Analysis, HPLC and Electrospray Ionization Mass Spectrometry (ESI-MS). The formation of amide bonds was evidenced in all systems studied. While the products of single amino acids activation on silica could be considered as evolutionary dead ends, (Glutamic acid + Leucine) and, at least to some extent, (Aspartic acid + Valine) gave rise to the high yield formation of linear peptides up to the hexamers. Oligopeptides of such length had not been observed before in surface polymerization scenarios (unless the amino acids had been deposited by chemical vapor deposition, which is not realistic prebiotically). Furthermore, not all possible amino acid sequences were present in the activation products, indicative of polymerization selectivity. These results are promising for origins of life studies since they suggest the emergence of non-random biopolymers in a simple prebiotic scenario. PMID- 30284765 TI - Isothiazolinone derivatives and allergic contact dermatitis: a review and update. AB - Allergic contact dermatitis (ACD) from isothiazolinones has frequently been described in the literature. Following an epidemic of sensitization to methylchloroisothiazolinone/ methylisothiazolinone (MCI/MI) in the 1980's, and more recently to MI, the Scientific Committee on Consumer Safety of the European Commission banned their use in leave-on products, whilst restricting that in rinse-off cosmetics. Despite a decreasing prevalence of allergic contact dermatitis from MCI/MI and MI, cases caused by occupational exposure and non cosmetic isothiazolinone sources are on the rise. Moreover, sensitization to newer and lesser known isothiazolinones has been reported. This paper reviews the epidemiology of contact allergy to different isothiazolinones, clinical presentation of isothiazolinone-induced allergic contact dermatitis, most relevant sensitization sources, and potential cross-reactions between isothiazolinone derivatives. It also provides an update on recent legislative measures. This article is protected by copyright. All rights reserved. PMID- 30284766 TI - Stereoselective Sensing of l- and d-Amino Acids: Development of a Fluorescence Array Based on Readily Available Chiral Phosphoric Acids. AB - The identification of structurally related analytes has become possible using sensor arrays, based on sets of cross-reactive chemosensors. This work reports the use of readily available chiral phosphoric acids for the array-based, chemo- and stereoselective sensing of l- and d-amino acids. Six bis- and trisphosphoric acids were used in combination with Ni2+ and Eu3+ , resulting in a set of twelve chiral fluorescent chemosensors. This sensor-array enables a correct classification of l-amino acids with 100 % accuracy, while the differentiation between l- and d-amino acids can be achieved with 94 % accuracy. In addition, the systematic analysis of sensor contributions has allowed the use of a reduced set of seven sensors for the classification of l-amino acids, thus drastically reducing the amount of necessary measurements. PMID- 30284767 TI - Interarm Blood Pressure Difference is Associated with Early Neurological Deterioration, Poor Short-Term Functional Outcome, and Mortality in Noncardioembolic Stroke Patients. AB - BACKGROUND AND PURPOSE: Interarm differences in the systolic and diastolic blood pressures (IASBD and IADBD, respectively) are found in various populations, including stroke patients, but their significance for stroke outcomes has rarely been reported. We aimed to determine the associations of IASBD and IADBD with early neurological deterioration (END), functional outcome, and mortality. METHODS: This study included 1,008 consecutive noncardioembolic cerebral infarction patients who were admitted within 24 hours of onset and had automatic measurements of blood pressures in the bilateral arms. END was assessed within 72 hours of stroke onset according to predefined criteria. A poor functional outcome was defined as a score on the modified Rankin Scale >=3 at 3 months after the index stroke. All-cause mortality was also investigated during a median follow-up of 24 months. The absolute difference of blood pressure measurements in both arms were used to define IASBD and IADBD. RESULTS: END occurred in 15.3% (155/1,008) of the patients. A multivariate analysis including sex, age, and variables for which the p value was <0.1 in a univariate analysis revealed that IASBD >=10 mm Hg was significantly associated with END [odds ratio (OR)=1.75, 95% CI=1.02 3.01]. IADBD >=10 mm Hg was also related to END (OR=3.11, 95% CI=1.61-5.99). Moreover, having both IASBD >=10 mm Hg and IADBD >=10 mm Hg was related to a poor functional outcome (OR=2.67, 95% CI=1.36-5.35) and mortality (hazard ratio=7.67, 95% CI=3.76-12.83) even after adjusting for END. CONCLUSIONS: This study suggests that an interarm blood pressure difference of >=10 mm Hg could be a useful indicator for the risks of END, poor functional outcome, and mortality.

Tension-type headache (TTH) is the most common type of primary headache and has negative impacts on the quality of life and work performance. We aimed to determinethe relationship between TTH and insufficient sleep in the general population. METHODS: This study used data from the Korean Headache Sleep Study, which was a population-based survey about headache and sleep among Korean adults. Insufficient sleep was defined when the discrepancy between sleep need and average sleep duration was at least 1 hour. RESULTS: Among the 2,695 included subjects, 570 (21.2%) and 727 (27.0%) were classified as having TTH and insufficient sleep, respectively. The prevalence of insufficient sleep was significantly higher among subjects with TTH than among those without headaches (28.8% vs. 20.4%). For subjects with TTH, the scores on a visual analogue scale (4.7+/-1.8 vs. 4.3+/-1.9, mean+/-SD) and the Headache Impact Test-6 (44.9+/-7.0 vs. 43.6+/-6.1) were much higher in subjects with insufficient sleep than in those without insufficientsleep. Multivariable analyses revealed that insomnia [odds ratio (OR)=2.1], poor sleep quality (OR=1.7), and short sleep duration (OR=6.9) were significantly associated with insufficient sleep in subjects with TTH. CONCLUSIONS: Our findings suggest that insufficient sleep is prevalent among subjects with TTH and is linked to an exacerbation of TTH. Therefore, the proper evaluation and management of sleep may lead to the better management of TTH.

AB - OBJECTIVE: Our study aimed to elucidate the interactive relationship between factors associated with dental caries in school children using decision tree analysis. RESEARCH DESIGN: Cross-sectional study Methods: Participants were recruited from public primary schools (9-12 years, 4th to 6th grade) and junior high schools (12-13 years, 1st grade) in Japan. A total of 1775 students (928 boys and 847 girls) were analyzed. Questionnaire survey, oral examination, and saliva test were performed. Multiple logistic regression and decision tree analysis were performed. RESULTS: Multiple logistic regression showed an association between dental caries and toothpaste use, dental attendance and the presence of Streptococcus mutans. Decision tree analysis showed that students with non-regular dental attendance were at a significantly higher risk of dental caries at the late stage of primary school. At the early stage of primary school, high levels of Streptococcus mutans and male sex were factors associated with dental caries. In students with low levels of Streptococcus mutans, using toothpaste occasionally was associated with a high risk of dental caries. CONCLUSIONS: In early primary school years, S. mutans may be a useful screening and diagnostic tool for dental caries. In students with high levels of S. mutans, sex may be associated with dental caries. Furthermore, in students with low levels of S. mutans, regular use of toothpaste should be encouraged, and in late primary school years, regular dental attendance should be encouraged to prevent dental caries.

AB - BACKGROUND: In order to address the burden of oral disease, the dental profession needs to engage in collaborative practice with medical professionals. The aim of this study was to explore dentists' views on incorporating oral health collaborative practice into primary medical care in Ireland. SETTING: Dublin Dental University Hospital, Ireland. PARTICIPANTS: Dentists with backgrounds in oral surgery, oral medicine, paediatric dentistry, special care dentistry, prosthodontics, primary care dentistry, hospital dentistry and public dental health. All participants were working in, or had worked in, Dublin Dental University Hospital for a minimum of six months full-time equivalent within the previous 5 years. METHODS: Semi-structured qualitative interviews were undertaken in five phases, transcribed verbatim and thematically analyzed. RESULTS: A total of 17 participants were recruited. After 14 interviews, no new themes were emerging and data saturation was achieved. Eleven codes were identified and organized into four themes; (i) the relative importance of oral health to systemic health, (ii) the role of dentistry in the overall health care team, (iii) oral health interprofessional education and training, (iv) opportunities for oral health collaborative practice. CONCLUSION: Dentists felt that the best way to achieve effective oral health collaborative practice with primary medical care would be to educate medical professionals on how to identify the significant risk factors for oral disease, how to promote oral health and how to facilitate access to primary dental care for their patients. PMID- 30284778 TI - Assessing and managing malnutrition in adults in hospital. AB - The term malnutrition refers to both undernutrition and overnutrition. In healthcare, it most often refers to undernutrition, in particular disease-related malnutrition, which can be a result or a cause of an illness. The reasons for malnutrition are multifactorial, and its consequences may include an increased risk of pressure ulcers, reduced mobility and psychological effects such as depression. It is essential that nurses prioritise the nutritional care of all patients and identify those at risk of malnutrition using accurate and reliable nutrition screening tools. If there is a risk of malnutrition, further assessment and nutrition action planning can reduce the risk to the patient and improve their nutritional status. This article discusses the effects of disease-related malnutrition and outlines the role of screening tools and assessment in identifying patients who are malnourished or at risk of becoming malnourished. It also describes the nursing care that should be provided to patients with disease related malnutrition, and emphasises the importance of using a multidisciplinary team approach involving speech and language therapists, dieticians, occupational therapists and physiotherapists.

PMID- 30284805 TI - Repeated Intrinsic Self-Healing of Wider Cracks in Polymer via Dynamic Reversible Covalent Bonding Molecularly Combined with a Two-Way Shape Memory Effect. AB - To enable repeated intrinsic self-healing of wider cracks in polymers, a proof-of concept approach is verified in the present work. It operates through two-way shape memory effect (SME)-aided intrinsic self-healing. Accordingly, a reversible C-ON bond is introduced into the main chain of crosslinked polyurethane (PU) containing an elastomeric dispersed phase (styrene-butadiene-styrene block copolymer, SBS). The PU/SBS blend was developed by the authors recently, and proved to possess an external stress-free two-way SME after programming. As a result, the thermal retractility offered by the SME coupled with the reversible C ON bonds can be used for successive crack closure and remending based on synchronous fission/radical recombination of C-ON bonds. Moreover, multiwalled carbon nanotubes are incorporated to impart electrical conductivity to the insulating polymer. Repeated autonomic healing of wider cracks is thus achieved through narrowing of cracks followed by chemical rebonding under self-regulating Joule heating. No additional programming is needed after each healing event, which is superior to one-way SME-assisted self-healing. The outcomes set an example of integrating different stimuli-responsivities into single materials. PMID- 30284806 TI - Chronic Social Isolation Stress during Peri-Adolescence Alters Presynaptic Dopamine Terminal Dynamics via Augmentation in Accumbal Dopamine Availability. AB - Chronic peri-adolescent stress in humans increases risk to develop a substance use disorder during adulthood. Rats reared in social isolation during peri adolescence (aSI; 1 rat/cage) period show greater ethanol and cocaine intake compared to group housed (aGH; 4 rats/cage) rats. In addition, aSI rats have a heightened dopamine response in the nucleus accumbens (NAc) to rewarding and aversive stimuli. Furthermore, single pulse electrical stimulation in slices containing NAc core elicits greater dopamine release in aSI rats. Here, we further investigated dopamine release kinetics and machinery following aSI. Dopamine release, across a wide range of stimulation intensities and frequencies, was significantly greater in aSI rats. Interestingly, subthreshold intensity stimulations also resulted in measurable dopamine release in accumbal slices from aSI but not aGH rats. Extracellular [Ca2+] manipulations revealed augmented calcium sensitivity of dopamine release in aSI rats. The readily releasable pools of dopamine, examined by bath application of Ro-04-1284/000, a vesicular monoamine transporter 2 (VMAT2) inhibitor, were depleted faster in aGH rats. Western blot analysis of release machinery proteins (VMAT2, Synaptogyrin-3, Syntaxin-1, and Munc13-3) showed no difference between the two groups. Tyrosine hydroxylase (TH) protein expression levels, however, were elevated in aSI rats. The greater dopamine release could potentially be explained by higher levels of TH, the rate-limiting step for dopamine synthesis. This augmented responsivity of the dopamine system and heightened dopamine availability post-aSI may lead to an increased risk of addiction vulnerability. PMID- 30284807 TI - Design of Gold Hollow Nanorods with Controllable Aspect Ratio for Multimodal Imaging and Combined Chemo-Photothermal Therapy in the Second Near-Infrared Window. AB - Gold nanoparticles (AuNPs) exhibit great potential for biological applications due to their good biocompatibility and tunable localized surface plasmon resonance (LSPR) properties. Currently, although tuning the aspect ratio of a solid structure or designing a hollow structure has been performed to regulate the LSPR properties of AuNPs, the method of preparing hollow anisotropic AuNPs has rarely been reported. In this study, we designed gold hollow nanorods (AuHNRs) with controllable aspect ratios by a Se-doping Te nanorod-templated method with the assistance of l-cysteine. UV-vis-NIR spectra showed that AuHNRs with an aspect ratio of about 3 could have a LSPR peak in the second near infrared (NIR-II) window, which is only half of the value required by traditional Au nanorods. Moreover, AuHNRs are nontoxic and capable of loading drugs. In vivo experiment revealed that AuHNRs can be used as contrast agents in multimodal imaging, including photothermal imaging, photoacoustic imaging, and computed tomography imaging, as well as in chemo-photothermal combined therapy of tumor in the NIR-II window. Because light in the NIR-II window has remarkable advantages over that in the first near-infrared (NIR-I) window in biomedical applications, AuHNRs can be used as promising NIR-II-window-responsive multifunctional nanoagents. PMID- 30284808 TI - Long Cycle Life All-Solid-State Sodium Ion Battery. AB - All-solid-state sodium ion batteries (ASIBs) based on sulfide electrolytes are considered a promising candidate for large-scale energy storage. However, the limited cycle life of ASIBs largely restricts their practical application. Cycling-stable ASIBs can be achieved only if the designed cathode can simultaneously address challenges including insufficient interfacial contact, electrochemical and chemical instability between the electrode and electrolyte, and strain/stress during operation , rather than just addressing one or part of these challenges. Chevrel phase Mo6S8 has inherent high electronic conductivity and small volume change during sodiation/desodiation, and is chemically and electrochemically stable with the sulfide electrolyte, and therefore the only challenge of using Mo6S8 as the cathode for ASIBs is the insufficient contact between Mo6S8 and the solid electrolyte (SE). Herein, a thin layer of SE is coated on Mo6S8 using a solution method to achieve an intimate contact between Mo6S8 and the SE. Such a SE-coated Mo6S8 cathode enabled an ASIB with a high cycling performance (500 cycles), even much better than that of the liquid electrolyte batteries with the Mo6S8 cathode. This work provides valuable insights for developing long-cycle life ASIBs. PMID- 30284809 TI - Nanotechnology in Neuroscience Reveals Membrane Mobility Matters.

PMID- 30284810 TI - Direct Evaluation of Live Uropathogenic Escherichia coli Adhesion and Efficiency of Antiadhesive Compounds Using a Simple Microarray Approach. AB - Many pathogens use host glycans as docking points for adhesion. Therefore, the use of compounds blocking carbohydrate-binding adhesins is a promising strategy for fighting infections. In this work, we describe a simple and rapid microarray approach for assessing the bacterial adhesion and efficiency of antiadhesive compounds targeting uropathogenic Escherichia coli UTI89, which displays mannose specific adhesin FimH at the tip of fimbriae. The approach consisted in direct detection of live fluorescently labeled bacteria bound to mannan printed onto microarray slides. The utility of the arrays for binding/inhibition assays was first validated by comparing array-derived results for the model mannose-binding lectin concanavalin A with data obtained by isothermal titration calorimetry. Growth phase-dependent binding of UTI89 to the arrays was observed, proving the usefulness of the setup for detecting differences in FimH expression. Importantly, bacteria labeling and binding assays entailed minimal manipulation, helping to preserve the integrity of fimbriae. The efficiency of three different dodecamannosylated fullerenes as FimH-targeted antiadhesives was next evaluated in competition assays. The results revealed a superior activity of the mannofullerenes (5- to 18-fold per mannose residue) over methyl alpha-d mannopyranoside. Moreover, differences in activity were detected for mannofullerenes differing in the structure/length of the spacer used for grafting mannose onto the fullerene core, further demonstrating the sensitivity of the assay. Overall, the approach combines straightforward and time-saving protocols for microarray preparation, bacteria labeling, and binding assays, and it can be easily tailored to other bacteria bearing carbohydrate-binding adhesins.

PMID- 30284812 TI - Salvaging the thermodynamic destabilization of interface histidine in transmembrane beta-barrels. AB - The ability of histidine to participate in a wide range of stabilizing polar interactions preferentially populates this residue in functionally important sites of proteins. Histidine possesses an amphiphilic and electrostatic nature essential for amino acids residing at membrane interfaces. However, the frequency of occurrence of histidine at membrane interfaces, particularly transmembrane beta-barrels, is lower than other aromatic residues. Here, we carry out comprehensive energetic measurements using equilibrium folding of the outer membrane enzyme PagP, to address the contribution of a C-terminal interface histidine on barrel stability. We show that placing histidine at the C-terminus universally destabilizes PagP by 4.0-8.0 kcal mol-1 irrespective of the neighboring residue. Spectroscopic and electrophoretic measurements indicate that the altered stability may arise from a loss in barrel compaction. Isoleucine, methionine, and valine salvage this destabilization marginally (in addition to tyrosine which shows an exceptionally high folding free energy value), when placed at the penultimate position, at the expense of an altered folding pathway. Double mutant cycle analysis indicates that the coupling energy between the terminal and penultimate residues in PagP-X160H161 increases when the intrinsic destabilization by the terminal H161 is high. Our observations that neighboring residues cannot salvage the energetic destabilization of histidine may explain why histidine is less abundant at membrane interfaces. PMID- 30284813 TI - Biodegradable Anisotropic Microparticles for Stepwise Cell Adhesion and Preparation of Janus Cell Microparticles. AB - The biomimetic anisotropic particles have different physicochemical properties on the opposite two sides, enabling diverse applications in emulsion, photonic display, and diagnosis. However, the traditional anisotropic particles have a very small size, ranging from submicrons to a few microns. The design and fabrication of anisotropic macron-sized particles with new structures and properties is still challenging. In this study, anisotropic polycaprolactone (PCL) microparticles well separated with each other were prepared by crystallization from the dilute PCL solution in a porous 3D gelatin template. They had fuzzy and smooth surfaces on each side, and a size as large as 70 MUm. The fuzzy surface of the particle adsorbed significantly larger amount of proteins, and was more cell-attractive regardless of the cell types. The particles showed stronger affinity toward fibroblasts over hepatocytes, which paved a new way for cell isolation merely based on the surface morphology. After a successive seeding process, Janus cell microparticles with fibroblasts and endothelial cells (ECs) on each side were designed and obtained by making use of the anisotropic surface morphology, which showed significant difference in EC functions in terms of prostacyclin (PGl2) secretion, demonstrating the unique and appealing functions of this type of anisotropic microspheres.

AB - Solid-state nanopores have a huge potential in upcoming societal challenging applications in biotechnologies, environment, health, and energy. Nowadays, these sensors are often used within bulky fluidic devices that can cause cross contaminations and risky nanopore chips manipulations, leading to a short experimental lifetime. We describe the easy, fast, and cheap innovative 3D printer-helped protocol to manufacture a microfluidic device permitting the reversible integration of a silicon based chip containing a single nanopore. We show the relevance of the shape of the obtained channels thanks to finite elements simulations. We use this device to thoroughly investigate the ionic transport through the solid-state nanopore as a function of applied voltage, salt nature, and concentration. Furthermore, its reliability is proved through the characterization of a polymer-based model of protein-urea interactions on the nanometric scale thanks to a hairy nanopore. PMID- 30284815 TI - Integration of Zn-Ag and Zn-Air Batteries: A Hybrid Battery with the Advantages of Both. AB - We report a hybrid battery that integrates a Zn-Ag battery and a Zn-air battery to utilize the unique advantages of both battery systems. In the positive electrode, Ag nanoparticles couple the discharge behaviors through the two distinct electrochemical systems by working as the active reactant and the effective catalyst in the Zn-Ag and Zn-air reactions, respectively. In the negative electrode, in situ grown Zn particles provide large surface areas and suppress the dendrite, enabling the long-term operating safety. The battery first exhibits two-step voltage plateaus of 1.85 and 1.53 V in the Zn-Ag reaction, after which a voltage plateau of 1.25 V is delivered in the Zn-air reaction, and the specific capacity reaches 800 mAh gZn-1. In addition, excellent reversibility and stability with maintaining high energy efficiency of 68% and a capacity retention of nearly 100% at 10 mA cm-2 are demonstrated through 100 cycles, outperforming both conventional Zn-air and Zn-Ag batteries. This work brings forth a conceptually novel high-performance battery, and more generally opens up new vistas for developing hybrid electrochemical systems by integrating the advantages from two distinct ones. PMID- 30284816 TI - Quadrupole Orbitrap Mass Spectrometer-Based Metabonomic Elucidation of Influences of Short-Term Di(2-ethylhexyl) phthalate Exposure on Cardiac Metabolism in Male Mice. AB - Di(2-ethylhexyl) phthalate (DEHP) can cause severe environmental pollution. Effects of DEHP on cardiac metabolism have been reported, but its mechanism(s) of action is not fully clear. Here, we used high-resolution mass spectrometry for metabonomics and molecular biological methods to identify the different endogenous metabolites affected by DEHP that might cause changes in cardiac metabolism in mice, map the network of metabolic pathways, and reveal (at the molecular level) how DEHP affects cardiac metabolism. The results showed that DEHP could inhibit the beta-oxidation of fatty acids and gluconeogenesis, promote glycolysis, and inhibit the tricarboxylic acid cycle in cardiomyocytes. DEHP caused mitochondrial dysfunction by inhibiting the synthesis and transport of fatty acids and, thus, inhibiting the synthesis and breakdown of adenosine triphosphate in mitochondria. Pathology revealed that DEHP could change the normal structures and functions of the heart and bodies of mice. DEHP can interfere with the physiological and metabolic function of the heart in mice by disrupting the endogenous metabolite and gene levels. PMID- 30284817 TI - Evaluation of Deuterium-Labeled JNJ38877605: Pharmacokinetic, Metabolic, and in Vivo Antitumor Profiles. AB - c-Met inhibitor JNJ38877605 has proven curative as an antitumor agent, while its clinical study was terminated due to renal toxicity. It was reported that the renal toxicity was caused by the poor solubility of its aldehyde oxidase (AO) metabolites. Therefore, blocking AO oxidation of JNJ38877605 might diminish the toxic metabolites and overcome the renal toxicity. Compound 3, the AO metabolic site deuterated JNJ38877605, was then synthesized as the target molecule. In vitro monkey liver S9 fraction incubation of 3 manifested that the renal toxic metabolite M2-2 was significantly reduced, which connoted that this deuteration has partly blocked AO oxidation. After po. nasal gavage to cynomolgus monkeys, compound 3 revealed decreased AO metabolites M2-2 and M3-2 in the plasma as well as 1.88-fold AUC and 1.56-fold Cmax compared with JNJ38877605, indicating that deuterium replacement significantly blocked AO metabolism in vivo. Besides, metabolic profiles of 3 were investigated by analysis of the plasma and the urine of the po. administrated cynomolgus monkeys. Moreover, after oral administration to the EBC-1 tumor-bearing nude mice, compound 3 exhibited a better antitumor efficacy than JNJ38877605. In conclusion, deuteration on the AO metabolic site of JNJ38877605 improved its AO metabolism, oral exposure, as well as in vivo antitumor efficacy. PMID- 30284818 TI - In Situ Measurement of the Size Distribution and Concentration of Insulating Particles by Electrochemical Collision on Hemispherical Ultramicroelectrodes. AB - One of the greatest limitations in electrochemical collision/nanoimpact methods is the inability to quantify the size of colliding species due to the uneven current distribution on a disk ultramicroelectrode UME (so-called edge effect). This phenomenon arises since radial diffusion is greater at the edge than the center of the active electrode surface. One method of solving this problem is fabrication of a hemispherical UME. We describe the fabrication of a hemispherical Hg UME on a disk UME by a solution-based electrochemical method, chronocoulometry. The use of hemispherical Hg UME to detect collisions of individual amine-functionalized polystyrene beads removes the "edge effect" and enables simultaneous measurements of the concentration and the size distribution of colloids in suspension. Using finite element simulations, we deduce a quantitative relation between the distribution of current step size and the size distribution of the bead. The frequency of collision measured for a given size of bead is then converted into a concentration (in mol/L) by a quantification of the relative contributions of migration and diffusion for each size of bead. Under our experimental conditions (low concentration of supporting electrolyte), migration dominates the flux of bead. The average size of polystyrene beads of 0.5 and 1 MUm radius obtained by electrochemistry and scanning electron microscopy (SEM) differs by only -8% and -9%, respectively. The total concentration of polystyrene beads of 0.5 and 1 MUm radius obtained by electrochemistry is found in close agreement (<10% of error) with their nominal concentrations (25 and 100 fM). PMID- 30284819 TI - Screening and characterization of novel polyesterases from environmental metagenomes with high hydrolytic activity against synthetic polyesters. AB - The continuous growth of global plastics production, including polyesters, has resulted in increasing plastic pollution and subsequent negative environmental impacts. Therefore, enzyme-catalyzed depolymerization of synthetic polyesters as a plastics recycling approach has become a focus of research. In this study, we screened over 200 purified uncharacterized hydrolases from environmental metagenomes and sequenced microbial genomes and identified at least 10 proteins with high hydrolytic activity against synthetic polyesters. These include the metagenomic esterases MGS0156 and GEN0105, which hydrolyzed polylactic acid (PLA), polycaprolactone, as well as bis(benzoyloxyethyl)-terephthalate. With solid PLA as a substrate, both enzymes produced a mixture of lactic acid monomers, dimers, and higher oligomers as products. The crystal structure of MGS0156 was determined at 1.95 A resolution and revealed a modified alpha/beta hydrolase fold, with a lid domain and highly hydrophobic active site. Mutational studies of MGS0156 identified the residues critical for hydrolytic activity against both polyester and monoester substrates, with two-times higher polyesterase activity in the MGS0156 L169A mutant protein. Thus, our work identified novel, highly active polyesterases in environmental metagenomes and provided molecular insights into their activity, thereby augmenting our understanding of enzymatic polyester hydrolysis.

AB - This study investigated the significant influence of HCO3- on the degradation of contaminants of emerging concern (CECs) during nitrate photolysis at 254 nm for water reuse applications. The second-order rate constants for the reactions between selected contaminants with carbonate radical (CO3*-) were determined at pH 8.8 and T = 20 degrees C: estrone ((5.3 +/- 1.1) * 108 M-1 s-1), bisphenol A ((2.8 +/- 0.2) * 108 M-1 s-1), 17alpha-ethynylestradiol ((1.6 +/- 0.3) * 108 M-1 s-1), triclosan ((4.2 +/- 1.4) * 107 M-1 s-1), diclofenac ((2.7 +/- 0.7) * 107 M 1 s-1), atrazine ((5.7 +/- 0.1) * 106 M-1 s-1), carbamazepine ((4.2 +/- 0.01) * 106 M-1 s-1), and ibuprofen ((1.2 +/- 1.1) * 106 M-1 s-1). Contributions from UV, reactive nitrogen species (RNS), hydroxyl radical (*OH), and CO3*- to the CEC decomposition in UV/NO3- in the presence and absence of HCO3- were investigated. In addition, possible transformation products and degradation pathways of triclosan, diclofenac, bisphenol A, and estrone in UV/NO3-/HCO3- were proposed based on the mass (MS) and MS2 spectra. Significant reduction in the cytotoxicity of bisphenol A was observed after the treatment with UV/NO3-/HCO3-.

AB - The 2S albumin Ara h 6 is one of the most important peanut allergens. A post translationally cleaved Ara h 6 (pAra h 6) was purified from Virginia type peanuts, and the cleavage site was mapped using high-resolution mass spectrometry. Compared to intact Ara h 6, pAra h 6 lacks a 5-amino acid stretch, resembling amino acids 43-47 (UniProt accession number Q647G9) in the nonstructured loop. Consequently, pAra h 6 consists of two chains: an N-terminal chain of approximately 5 kDa and a C-terminal chain of approximately 9 kDa, held together by disulfide bonds. Intermediate post-translationally cleaved products, in which this stretch is cleaved yet still attached to one of the subunits, are also present. The secondary structure and immunoglobulin E (IgE) binding of pAra h 6 resembles that of intact Ara h 6, indicating that the loss of the nonstructured loop is not critical for maintaining the protein structure. Commercially available monoclonal and polyclonal immunoglobulin G (IgG) antibodies directed to Ara h 6 react with both intact Ara h 6 and pAra h 6, suggesting that the involved epitopes are not located in the area that is post translationally cleaved. No differences between intact Ara h 6 and pAra h 6 in terms of IgE binding were found, suggesting that the area that is post translationally cleaved is not involved in IgE epitopes either. For all main cultivars Runner, Virginia, Valencia, and Spanish, intact Ara h 6 and pAra h 6 occur in peanut at similar levels, indicating that pAra h 6 is a consistent and important contributor to the allergenic potency of peanut.

AB - Recent work on superionic conductors has demonstrated the influence of lattice dynamics and the softness of the lattice on ionic transport. When examining either the changes in the acoustic phonon spectrum or the whole phonon density of states, both a decreasing activation barrier of migration and a decreasing entropy of migration have been observed, highlighting that the paradigm of "the softer the lattice, the better" does not always hold true. However, both approaches to monitor the changing lattice dynamics probe different frequency ranges of the phonon spectrum, and thus, it is unclear if they are complementary. In this work, we investigate the lattice dynamics of the superionic conductor Na3PS4- xSe x by probing the optical phonon modes and the acoustic phonon modes, as well as the phonon density of states via inelastic neutron scattering. Notably, Raman spectroscopy shows the evolution of multiple local symmetry reduced polyhedral species, which likely affect the local diffusion pathways. Meanwhile, density functional theory and the ionic transport data are used to compare the different approaches for assessing the lattice dynamics. This work shows that, while acoustic and inelastic methods may be used to experimentally assess the overall changing lattice stiffness, calculations of the average vibrational energies between the mobile ions and the anion framework are important to assess and computationally screen for ionic conductors.

AB - Herein, a copper-catalyzed intramolecular cascade reaction of conjugated enynones to deliver substituted 1 H-indenes is reported. The inexpensive and less toxic copper salt served as the only catalyst in the transformation, affording the 3-(2 furyl)-substituted 1 H-indenes in good to excellent yields under mild reaction conditions with broad functional group tolerance and making it highly appealing for synthetic organic chemistry. Notably, detailed DFT calculations have been carried out to elucidate that the reaction undergoes a copper-mediated 5- exo-dig cyclization of enynones to afford copper-(2-furyl)-carbene intermediate, followed by diene-carbene cyclization (one step but involving 6pi cyclization of Cu carbene and reductive elimination) and 1,5-hydrogen shift to provide the 1 H indenes. PMID- 30284823 TI - Photoactivation of MDM2 Inhibitors: Controlling Protein-Protein Interaction with Light. AB - Selectivity remains a major challenge in anticancer therapy, which potentially can be overcome by local activation of a cytotoxic drug. Such triggered activation can be obtained through modification of a drug with a photoremovable protecting group (PPG), and subsequent irradiation in the chosen place and time. Herein, the design, synthesis and biological evaluation is described of a photoactivatable MDM2 inhibitor, PPG-idasanutlin, which exerts no functional effect on cellular outgrowth, but allows for the selective, noninvasive activation of antitumor properties upon irradiation visible light, demonstrating activation with micrometer, single cell precision. The generality of this method has been demonstrated by growth inhibition of multiple cancer cell lines showing p53 stabilization and subsequent growth inhibition effects upon irradiation. Light activation to regulate protein-protein interactions between MDM2 and p53 offers exciting opportunities to control a multitude of biological processes and has the potential to circumvent common selectivity issues in antitumor drug development. PMID- 30284825 TI - Tuning the Optoelectronic Properties of Stannoles by the Judicious Choice of the Organic Substituents. AB - Stannoles are organometallic rings in which the heteroatom is involved in a form of conjugation that is called sigma*-pi* conjugation. Only very little is known about how the substituents on the Sn atom or substituents on the stannole ring determine the optoelectronic properties of these heterocycles. In this work, this question has been studied experimentally and theoretically. Calculations of optimized equilibrium geometries, energy gaps between the highest occupied molecular orbitals (HOMOs) and lowest unoccupied molecular orbitals (LUMOs), and of the absorption spectra of a wide range of compounds were performed. The computational data showed that the substituents on the Sn atom influence the optoelectronic properties to a lower extent than the substituents in the 2 and 5 positions of the ring. These substituents in the 2 and 5 positions of the stannole ring can also have a strong influence on the overall planarity of the structure, in which mesomeric effects can play a substantial role only if the structure is planar. Thus, only structures with a planar backbone are of interest in the context of tuning the optoelectronic properties. These were selected for the experimental studies. On the basis of this information, a series of six novel stannoles was synthesized by the formation of a zirconium intermediate and subsequent transmetalation to obtain the tin compound. The calculated electronic HOMO-LUMO energy gaps varied between 2.94 and 2.68 eV. The measured absorption maxima were located between 415 and 448 nm compared to theoretically calculated values ranging from 447 nm (2.77 eV) to 482 nm (2.57 eV). In addition to these optical measurements, cyclic voltammetry data could be obtained, which show two reversible oxidation processes for three of the six stannoles. With this study, it could be demonstrated how the judicious choice of the substituents can lead to large and predictable bathochromic shifts in the absorption spectra.

AB - We report here the chromium-catalyzed regioselective Kumada arylative cross coupling of C(aryl)-O bonds at ambient temperature. By using a simple and low cost chromium(II) chloride salt as a precatalyst, accompanied by a 2-pyridyl ligation, the catalytic cleavage and arylative coupling of C(aryl)-O bonds were achieved with a traceless activation strategy, overcoming the regioselectivity obstacle when several C-O bonds coexist in the Kumada coupling system. PMID- 30284827 TI - Total Synthesis of Complex Biosynthetic Late-Stage Intermediates and Bioconversion by a Tailoring Enzyme from Jerangolid Biosynthesis. AB - A highly convergent access to the late-stage biosynthetic intermediates projerangolid and jerangolid E is presented, and its utility is demonstrated by the synthesis of novel non-natural jerangolid derivatives. The key steps are fragment couplings by Julia-Kocienski olefination and olefin cross metathesis, as well as a stereoselective tetrahydropyran formation by intramolecular oxa-Michael addition. Bioconversion experiments with the tailoring O-methyltransferase JerF confirmed its proposed biosynthetic role and revealed relaxed substrate specificity of this enzyme as well as tolerance to organic cosolvents. PMID- 30284828 TI - A Synthesis of 3,4-Dihydroisoquinolin-1(2H)-one via the Rhodium-Catalyzed Alkylation of Aromatic Amides with N-Vinylphthalimide. AB - The alkylation of C-H bonds with N-vinylphthalimide by a rhodium-catalyzed reaction of aromatic amides containing an 8-aminoquinoline moiety as the directing group is reported. N-Vinylphthalimide functions as a 2-aminoethylating reagent. The resulting alkylated products can be converted into 3,4 dihydroisoquinolin-1(2H)-one derivatives in a one-pot transformation. Deuterium labeling experiments suggest that the reaction proceeds through a carbene mechanism. PMID- 30284829 TI - Single-Ion Thermodynamics from First Principles: Calculation of the Absolute Hydration Free Energy and Single-Electrode Potential of Aqueous Li+ Using ab Initio Quantum Mechanical/Molecular Mechanical Molecular Dynamics Simulations. AB - A recently proposed thermodynamic integration (TI) approach formulated in the framework of quantum mechanical/molecular mechanical molecular dynamics (QM/MM MD) simulations is applied to study the structure, dynamics, and absolute intrinsic hydration free energy Deltas GM+,wat? of the Li+ ion at a correlated ab initio level of theory. Based on the results, standard values (298.15 K, ideal gas at 1 bar, ideal solute at 1 molal) for the absolute intrinsic hydration free energy [Formula: see text] of the proton, the surface electric potential jump chiwat? upon entering bulk water, and the absolute single-electrode potential [Formula: see text] of the reference hydrogen electrode are calculated to be 1099.9 +/- 4.2 kJ.mol-1, 0.13 +/- 0.08 V, and 4.28 +/- 0.04 V, respectively, in excellent agreement with the standard values recommended by Hunenberger and Reif on the basis of an extensive evaluation of the available experimental data (-1100 +/- 5 kJ.mol-1, 0.13 +/- 0.10 V, and 4.28 +/- 0.13 V). The simulation results for Li+ are also compared to those for Na+ and K+ from a previous study in terms of relative hydration free energies DeltaDeltas GM+,wat? and relative electrode potentials [Formula: see text]. The calculated values are found to agree extremely well with the experimental differences in standard conventional hydration free energies DeltaDeltas GM+,wat* and redox potentials [Formula: see text]. The level of agreement between simulation and experiment, which is quantitative within error bars, underlines the substantial accuracy improvement achieved by applying a highly demanding QM/MM approach at the resolution-of identity second-order Moller-Plesset perturbation (RIMP2) level over calculations relying on purely molecular mechanical or density functional theory (DFT) descriptions. A detailed analysis of the structural and dynamical properties of the Li+ hydrate indicates that a correct description of the solvation structure and dynamics is achieved as well at this level of theory. Consideration of the QM/MM potential-energy components also shows that the partitioning into QM and MM zones does not induce any significant energetic artifact for the system considered. PMID- 30284830 TI - Atmospheric Fate of Criegee Intermediate Formed During Ozonolysis of Styrene in the Presence of H2O and NH3: The Crucial Role of Stereochemistry. AB - A gas-phase mechanistic investigation of the unimolecular, water/ammonia-assisted decomposition reactions of the alpha-hydroxy hydroperoxides (HPs) and hydroperoxide arylamines (a-HPs) produced during the styrene ozonolysis has been carried out theoretically in the present article. The instrumental role of stereochemistry in controlling the outcome of individual reactions has been discussed. Thermodynamic parameters (Delta G298K, Delta H298K, Delta E0K) associated with individual reactions have also been computed. The rate constants estimated for individual reactions using conventional transition state theory (TST) combined with statistical mechanics provide a comprehensive understanding of the reaction mechanism and also elucidate the atmospheric fate of Criegee intermediates. Considering the feasibility of reactions from thermodynamic and kinetic points of view, while aldehyde (PhCHO) formation pathway originating from bimolecular decomposition of HP is found to be kinetically favored, benzoic acid formation pathway remains favored thermodynamically. A similar consideration for the bimolecular reactions of a-HP reveals the phenylmethanimine formation pathway to be kinetically favored, while the benzamide formation pathway is favored thermodynamically. Our findings appear to be in excellent agreement with the experimental observations. PMID- 30284831 TI - Tracking DNA Synthesis with Single-Molecule Strand Displacement. AB - We have previously shown that double-stranded DNA labeled with a periodic series of fluorescent dyes can be used to track a single helicase. Here we demonstrate how this technique can be adapted to follow processive DNA synthesis. By monitoring strand displacement, we track the motion of a single phi29 DNA polymerase without labeling or altering the enzyme or the template strand, and without applying any force. We observe a wide range of speeds, with the highest exceeding by several times those observed in earlier in vitro single-molecule experiments. Because this method enables repeated observations of the same polymerase traversing identical segments of DNA, it should prove useful for determining the effects of sequence on DNA replication and transcription. In addition, future measurements of this type may allow us to examine in detail the interactions of individual DNA polymerases with other components of the replisome.

AB - A novel and efficient protocol for desulfonylation-initiated distal alkenyl migration and its application to the elusive alkenylation of unactivated alkenes have been presented. This radical cascade process has successfully achieved the vicinal difluoroalkylalkenylation of unactivated alkenes with excellent chemo-, regio-, and stereoselectivity in high efficiency under mild conditions. The reactions afford previously unknown 3,3-difluoro-5-styrylpiperidin-2-one derivatives or beta-styryl-gamma-difluoroalkyl amines bearing a quaternary stereocenter. This is the first report of difunctionalization of unactivated alkenes through desulfonylation-initiated distal alkenyl migration. PMID- 30284834 TI - Conformationally Unambiguous Spin Label for Exploring the Binding Site Topology of Multivalent Systems. AB - Multivalent carbohydrate-lectin interactions are a key concept in biological processes mediating, for example, signaling and adhesion. Binding affinities of multivalent ligands often increase by orders of magnitude compared to a monovalent binding situation. Thus, the design of multivalent ligands as potent inhibitors is a highly active field of research, where knowledge about the binding site topology is crucial. Here, we report a general strategy for precise distance measurements between the binding sites of multivalent target proteins using monovalent ligands. We designed and synthesized Monovalent, conformationally Unambiguously Spin-labeled LIgands (MUeSLI). Distances between the binding sites of the multivalent model lectin wheat germ agglutinin in complex with a GlcNAc-derived MUeSLI were determined using pulsed electron paramagnetic resonance spectroscopy. This approach is an efficient method for exploring multivalent systems with monovalent ligands, and it is readily transferable to other target proteins, allowing the targeted design of multivalent ligands without structural information available.

AB - A direct C(sp2)-H thiolation of aromatic amides with disulfides was developed. The coupling reaction proceeds between the thioether radical and cobaltacycle intermediate. This method exhibits a relatively broad substrate scope and high functional group compatibility. A mechanistic study indicates that the cobalt(IV) intermediate is probably formed during the course of the reaction. The thiolation product can be transformed to Quetiapine, which is an atypical antipsychotic agent approved for the treatment of schizophrenia and bipolar disorder. PMID- 30284835 TI - Quasi-Resonance Signal Amplification by Reversible Exchange. AB - Here we present the feasibility of NMR signal amplification by reversible exchange (SABRE) using radio frequency irradiation at low magnetic field (0.05 T) in the regime where the chemical shifts of free and catalyst-bound species are similar. In SABRE, the 15N-containing substrate and parahydrogen perform simultaneous chemical exchange on an iridium hexacoordinate complex. A shaped spin-lock induced crossing (SLIC) radio frequency pulse sequence followed by a delay is applied at quasi-resonance (QUASR) conditions of 15N spins of a 15N enriched substrate. As a result of this pulse sequence application, 15N z magnetization is created from the spin order of parahydrogen-derived hyperpolarized hydrides. The repetition of the pulse sequence block consisting of a shaped radio frequency pulse and the delay leads to the buildup of 15N magnetization. The modulation of this effect by the irradiation frequency, pulse duration and amplitude, delay duration, and number of pumping cycles was demonstrated. Pyridine-15N, acetonitrile-15N, and metronidazole-15N2-13C2 substrates were studied representing three classes of compounds (five- and six membered heterocycles and nitrile), showing the wide applicability of the technique. Metronidazole-15N2-13C2 is an FDA-approved antibiotic that can be injected in large quantities, promising noninvasive and accurate hypoxia sensing. The 15N hyperpolarization levels attained with QUASR-SABRE on metronidazole-15N2 13C2 were more than 2-fold greater than those with SABRE-SHEATH (SABRE in shield enables alignment transfer to heteronuclei), demonstrating that QUASR-SABRE can deliver significantly more efficient means of SABRE hyperpolarization.

AB - By employing reusable nanocobalt oxides as the catalysts, a site-specific oxidative C-H chalcogenation of (hetero)aryl-fused cyclic amines with various thiols and diselenides is presented for the first time. The reaction proceeds selectively at the sites of the (hetero)aryl rings para to the N atom, and enables access to a wide array of chalcogenyl N-heteroarenes. The merits of the transformation involve high step- and atom-efficiency, excellent substrate and functional compatibility, operational simplicity, and the use of a naturally abundant Co/O2 system. The present work has offered a fundamental basis for the selective synthesis of functional N-heteroarenes from readily available feedstocks.

PMID- 30284843 TI - Examining cognitive functioning of adult acute psychiatric inpatients through a brief screening assessment. AB - OBJECTIVE: Psychiatric inpatients present with multiple difficulties, including comorbid diagnoses, social problems, trauma, and high levels of psychiatric medication use. All of these factors have been associated with poorer cognitive functioning, which is rarely assessed. The aim of this study was to examine the acceptability of a brief cognitive screening assessment, and identify the cognitive and psychological profile of current psychiatric inpatients. METHOD: A cross-sectional design was adopted. Participants (N = 75) were administered brief measures of cognitive functioning, the Montreal Cognitive Assessment (MoCA; Nasreddine et al., 2005), and psychological global distress, Clinical Outcomes of Routine Evaluation-Outcome Measure, (CORE-OM; Evans et al., 2002) within the first 4 weeks of their hospital admissions. RESULTS: The MoCA was identified as acceptable for the inpatient environment. Most of the participants (79%) met the cut-off for mild cognitive impairment. No significant differences were found across diagnoses in regard to cognitive functioning, but participants with diagnoses of personality disorder experienced the most psychological global distress. CONCLUSION AND IMPLICATIONS FOR PRACTICE: Acute psychiatric inpatient wards should consider mild cognitive impairments when assessing and treating people with serious mental illness and make appropriate adaptations to their care.

AB - Emotional intelligence (EI) contributes to good performance and well-being in jobs that involve frequent interpersonal contact. However, as EI is composed of self- and other-focused dimensions, it remains unclear which dimensions are responsible for better performance and well-being. We hypothesized that other focused EI dimensions in particular relate to task performance, whereas self focused EI dimensions relate to employees' subjective stress and physiological responses to emotional job demands. We asked Dutch secretaries (N = 110) to professionally respond to five emotionally demanding work-related phone calls. The secretaries' skin conductance levels were recorded during the calls, and the secretaries had to indicate their stress levels after each call. Two independent raters coded the secretaries' effectiveness and the number of emotion regulation attempts during the phone calls. The results showed that other-focused emotion regulation was positively related to only one of the task performance indicators during three phone calls. In line with the hypotheses, self-focused emotion appraisal was negatively related to the secretaries' subjective stress levels after all the phone calls. Self-focused emotion regulation was positively related to the secretaries' skin conductance levels during all but one of the phone calls. This outcome suggests that self-focused EI dimensions decrease the subjective experience of stress but are accompanied by physiological costs, whereas other-focused emotion regulation may be positively but weakly related to task performance in emotionally demanding contexts.

AB - Work environment hypothesis, a predominant theoretical framework in workplace bullying literature, postulates that job characteristics may trigger workplace bullying. Yet, these characteristics are often assessed by employees based on their experience of the job. This study aims to assess how job characteristics, independently assessed via Occupational Information Network (O*NET), are related to perceived job characteristics reported by employees, which, in turn, are associated with self-reported workplace bullying. Multilevel mediation analyses from 3,829 employees in 209 occupations confirmed that employees, whose work schedules are more irregular and whose work involves a higher level of conflictual contact (as assessed by O*NET), report experiencing higher job demands, which are associated with higher exposure to bullying. Moreover, employees working in jobs structured to allow for more discretion in decision making (as assessed by O*NET) report experiencing more job autonomy and are less likely to experience bullying. The results offer some clues as to how the way in which a job is structured is related to how that job is perceived, which in turn is associated with exposure to bullying. Our findings also suggest that a job design perspective to redesign certain job characteristics may offer an additional viable approach to prevent workplace bullying.

AB - Using social-cognitive career theory, we identified the experiential sources of learning that contribute to research self-efficacy beliefs, outcome expectations, and science identity for culturally diverse undergraduate students in science, technology, engineering, and math (i.e., STEM) majors. We examined group differences by race/ethnicity and gender to investigate potential cultural variations in a model to explain students' research career intentions. Using a sample of 688 undergraduate students, we ran a series of path models testing the relationships between the experiential sources, research self-efficacy beliefs, outcome expectations, and science identity to research career intentions. Findings were largely consistent with our hypotheses in that research self efficacy and outcome expectancies were directly and positively associated with research career intentions and the associations of the experiential sources to intentions were mediated via self-efficacy. Science identity contributed significant though modest variance to research career intentions indirectly via its positive association with outcome expectations. Science identity also partially mediated the efficacy-outcome expectancies path. The experiential sources of learning were associated in expected directions to research self efficacy with 3 of the sources emerging as significantly correlated with science identity. An unexpected direct relationship from vicarious learning to intentions was observed. In testing for group differences by race/ethnicity and gender in subsamples of Black/African American and Latino/a students, we found that the hypothesized model incorporating science identity was supported, and most paths did not vary significantly across four Race/Ethnicity * Gender groups, except for 3 paths. Research and practice implications of the findings for supporting research career intentions of culturally diverse undergraduate students are discussed.

AB - The current study extended prior work on the Normative Male Alexithymia Scale (NMAS), a unidimensional measure of some men's limitations in expressing emotion that results from gender-based socialization informed by the masculine norm of restrictive emotionality (RE). Data (N = 505 men) were from Amazon Mechanical Turk participants. First, dimensionality was reassessed using exploratory factor analysis, which supported the unidimensional structure. Second, based on these results, three 6-item models of the NMAS-Brief Form (NMAS-BF) were developed, based on classical test theory (CTT), CTT optimized to avoid item redundancy, and item response theory (IRT). Third, the relative fits of these versions were assessed using confirmatory factor analysis on a separate part of the sample, finding that the IRT version was the best fitting model. Fourth, evidence for reliability for the NMAS-BF items (alpha = .80) and validity was found. Convergent evidence for validity was supported by a significant, moderate, positive correlation between the latent constructs of the NMAS-BF and Toronto Alexithymia Scale-20 (TAS-20), which measures clinical alexithymia. Concurrent evidence for validity of the latent factor of the NMAS-BF was assessed in a structural regression model which found that the NMAS-BF uniquely predicted RE scores when TAS-20 scores were included in the model. Finally, incremental evidence for validity was examined using hierarchical multiple regression, finding that NMAS-BF scores significantly predicted variance in RE scores above and beyond that predicted by TAS-20 scores. The results are discussed in relation to prior literature, future research directions, applications to counseling practice, and limitations.

PMID- 30284848 TI - Current status of forensic lie detection with the comparison question technique: An update of the 2003 National Academy of Sciences report on polygraph testing. AB - Fifteen years have elapsed since a report was released by the National Academy of Sciences (NAS) on the scientific status of polygraph testing. The NAS report concluded that the scientific basis of the comparison question technique (CQT) was weak, the extant research was of low quality, the polygraph profession's claims for the high accuracy of the CQT were unfounded, and, although the CQT has greater than chance accuracy, its error rate is unknown. Polygraph proponents argue that current research indicates that the CQT has 90% or better accuracy, the National Research Council of the National Academy of Sciences' (2003) analysis supports this accuracy claim, and the CQT qualifies as legally admissible scientific evidence. We review the scientific literature that has appeared since the appearance of the NAS publication, including a new method for estimating polygraph accuracy. We show that the NAS report has been misrepresented and misinterpreted by those who support use of the CQT in forensic settings. We conclude that the quality of research has changed little in the years elapsing since the release of the NAS report, and that the report's landmark conclusions still stand.

AB - Research has identified numerous factors that influence suspects during police interrogations. However, the dynamics between individuals' physiologic reactivity and their confession decision making is in its infancy. This research sought to advance the interrogation literature by examining the relationships among different interrogation tactics, suspects' resistance to confess, and their physiologic reactivity during a mock interrogation. After manipulating innocence and guilt, participants (N = 154) were accused and interrogated using either a minimization or false evidence tactic. Participants' physiologic reactivity was operationalized using their systolic blood pressure, and confession resistance was quantified as the number of times participants refused to confess. Results demonstrated that participants exhibited more physiologic reactivity after being confronted with false evidence ploys than minimization. Furthermore, innocent participants resisted confessing more than guilty participants, but innocents confronted with false evidence resisted confessing to a greater extent than innocents confronted with minimization. Moreover, a moderated-mediation analysis indicated that although innocents resisted confessing more when confronted with false evidence than those confronted with minimization, these innocents sustained a significantly higher level of physiologic reactivity. The results of the conditional indirect relationship suggest that innocents who are confronted with false evidence may resist the most but at a cost-their greater resistance may exhaust them and undermine subsequent decision making. These results offer support for reforms aimed at reducing the length of interrogations and the use of interrogation tactics that unnecessarily increase false confession rates.

PMID- 30284850 TI - Perceived discrimination and well-being among unauthorized Hispanic immigrants: The moderating role of ethnic/racial group identity centrality. AB - OBJECTIVES: We investigated the association between perceived ethnic discrimination with psychological well-being and life satisfaction among a community sample of unauthorized Hispanic immigrants in the United States. We also assessed whether ethnic/racial group identity centrality moderated this relationship. METHOD: A community sample of self-reported unauthorized Hispanics (N = 140) completed questionnaires assessing perceived ethnic discrimination, ethnic/racial group identity centrality, psychological well-being, and life satisfaction. RESULTS: Discrimination negatively predicted psychological well being and life satisfaction, and ethnic/racial group identity centrality moderated these relationships. High ethnic/racial group identity centrality reduced the association of discrimination with psychological well-being and life satisfaction. Ethnic/racial identity centrality lent psychological protection for those who reported higher levels of discrimination. CONCLUSION: Ethnic discrimination is a salient stressor for unauthorized Hispanic immigrants. Yet high ethnic/racial group identity centrality may protect these individuals from the negative effects of discrimination by providing a sense of belonging, acceptance, and social support in the face of rejection.

PMID- 30284851 TI - Ethnic-racial socialization in Latino families: The influence of mothers' socialization practices on adolescent private regard, familism, and perceived ethnic-racial discrimination. AB - OBJECTIVES: Cultural value endorsement and ethnic-racial identity promote Latino/a adolescent positive adaptation and mitigate the negative impacts of perceived ethnic-racial discrimination. This study explored the intergenerational process of how adolescents develop these cultural characteristics in concert with their experiences of discrimination, focusing on the role of youth-reported maternal ethnic-racial socialization processes. METHOD: Participants included 175 Latino/a adolescent-mother dyads recruited from the 7th and 8th grades in an understudied emerging immigrant destination. We tested the effects of maternal cultural characteristics (i.e., familism, private regard, and perceived discrimination) on the same adolescent outcomes through youth-reported maternal ethnic-racial socialization practices (i.e., cultural socialization, preparation for bias, promotion of mistrust, and familism socialization, a novel construct introduced in this study). RESULTS: Three significant indirect pathways were identified. Higher maternal private regard was associated with both higher youth familism and higher youth private regard through greater youth-reported familism socialization, and higher maternal private regard was associated with more perceived youth discrimination through greater youth-reported preparation for bias. CONCLUSION: Our results highlight maternal private regard as particularly important for understanding how youth perceptions of socialization processes encourage the development of adolescent cultural characteristics and the benefit of using specific assessment tools, such as a familism socialization measure, to identify how ethnic-racial socialization processes serve as intergenerational links. Directions for future research and implications for intervention are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30284852 TI - The effects of social power and apology on victims' posttransgression responses. AB - The purpose of this research was to test how, why, and when social power influences victims' revenge seeking, grudge holding, and forgiveness. Based on Keltner, Gruenfeld, and Anderson's (2003) power approach theory and McCullough, Kurzban, and Tabak's (2013) theorizing about revenge and forgiveness systems, we tested (a) the associations between victims' social power and revenge, grudge, and forgiveness; (b) the mediational role of approach/inhibition motivation in explaining why the associations exist; and (c) the moderating role of whether the transgressor apologizes or not in explaining the associations. Five studies (Ns = 279, 181, 154, 131, and 81) that varied in sample (undergraduate, community), research method (nonexperimental, experimental), context (laboratory, online), measures (self-reported, behavioral), and statistical method (regression, ANOVA), supported our predictions and the systematic generalizability of the effects. Applied implications are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30284853 TI - Conjoint differences in inhibitory control and processing speed in childhood to older adult cohorts: Discriminant functions from a Go/No-Go task. AB - To investigate differences in inhibitory control and processing speed over the life span, participants in 7- to 8-, 10- to 11-, 12- to 15-, 18- to 25-, and 54- to 80-year-old age cohorts completed a Go/No-Go task requiring varying levels of semantic categorization. Discriminant function analysis of correct rejection rates (CRRs), hit rates (HRs), and reaction times (RTs) revealed a function on which CRR loaded positively and RT loaded negatively, across categorization levels. Scores increased from youngest to the younger adult cohort and decreased for the older adult cohort. On a second function, CRR and RT loaded positively and HR loaded negatively across categorization levels. Scores were highest for the older adult cohort and higher for the youngest cohort than for the younger adult cohort. The results suggest change along 2 dimensions might underlie cognitive development: (a) combined increased inhibitory control and processing speed and (b) combined increased speed and decreased biased responding for better inhibitory control. In addition, 2 dimensions might underlie senescence: (a) combined decreased inhibitory control and processing speed and (b) combined decreased speed and increased biased responding for better inhibitory control.

AB - Verbal working memory-intensive sentence processing declines with age. This might reflect older adults' difficulties with reducing the memory load by grouping single words into multiword chunks. Here we used a serial order task emphasizing syntactic and semantic relations. We evaluated the extent to which older compared with younger adults may differentially use linguistic constraints during sentence processing to cope with verbal working memory limitations. Probing syntactic semantic interactions, age differences were hypothesized to be confined to the use of syntactic constraints and to be accompanied by an increased reliance on semantic information. Two experiments varying in verbal working memory demands were conducted: the sequence length was increased from eight items in Experiment 1 to 11 items in Experiment 2. We found the use of syntactic constraints to be compromised with aging, while the benefit of semantic information for sentence processing was comparable across age groups. Hence, we suggest that semantic information processing may become relatively more important for successful sentence processing with advancing adult age, possibly inducing a syntactic-to semantic-processing strategy shift.

PMID- 30284855 TI - Risk of progression to Alzheimer's disease for different neuropsychological Mild Cognitive Impairment subtypes: A hierarchical meta-analysis of longitudinal studies. AB - Mild Cognitive Impairment (MCI) is a heterogeneous condition between normal aging and dementia. Upon neuropsychological testing, MCI can be divided into 4 groups: single-domain amnestic MCI (sd-aMCI), multiple-domain amnestic MCI (md-aMCI), single- and multiple-domain nonamnestic MCI (sd-naMCI, md-naMCI). Some controversy exists about whether the risk of progression to Alzheimer's disease (risk-AD) is increased in all MCI subtypes. We meta-analyzed the risk-AD for 4 MCI groups using random-effects metaregression with the Hierarchical Robust Variance Estimator and sample size, criterion for objective cognitive impairment, length of follow-up and source of recruitment as covariates. From a pool of 134 available studies, 81 groups from 33 studies (N = 4,907) were meta-analyzed. All the studies were rated as having a high risk of bias. aMCI is overrepresented in studies from memory clinics. Multivariate analyses showed that md-aMCI had a similar risk-AD relative to sd-aMCI, whereas both sd-naMCI and md-naMCI showed a lower risk-AD compared with sd-aMCI. The risk-AD was significantly associated with differences in sample sizes across studies and between groups within studies. md-aMCI had a similar risk-AD relative to sd-aMCI in studies from memory clinics and in studies in the community. Several potential sources of bias such as blindness of AD diagnosis, the MCI diagnosis approach and the reporting of demographics were associated with the risk-AD. This work provides important data for use in both clinical and research scenarios. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30284856 TI - Higher self-stigma is related to lower likelihood of disclosing military sexual trauma during screening in female veterans. AB - OBJECTIVE: Recent prevalence estimates indicate 38% of female service members/veterans (SM/Vs) report military sexual trauma (MST). This estimate is higher than Veterans Affairs estimates, which suggest 28% report MST during screening. The discrepant estimate suggests possible barriers to disclosing MST, which are not well-identified in the literature. The current study examined whether being assaulted by a fellow unit member and stigma for seeking help to treat the sequelae of MST from self, unit leader/command, and romantic partners were correlates of MST nondisclosure among 209 female SM/Vs. METHOD: Participants completed a self-report questionnaire assessing MST nondisclosure, MST assailant characteristics, and stigma from the aforementioned sources as well as demographic, military, and mental health characteristics. Logistic regression analyses adjusting for military rank, MST severity, age, marital status and satisfaction, and probable mental health diagnoses determined whether being assaulted by a fellow unit member (yes/no) or stigma from various sources were associated with MST nondisclosure. RESULTS: Thirty-seven (17.70%) participants did not disclose MST during a previous screening. At the bivariate level, participants who did not disclose MST reported higher self-stigma and anticipated enacted stigma from unit leader/command and romantic partner. After adjusting for covariates, only higher self-stigma was associated with MST nondisclosure. CONCLUSIONS: Female veterans who report higher self-stigma were less likely to disclose their MST during screening. Such findings are consistent with previous literature demonstrating that self-stigma, relative to other forms of stigma, relates to lower help-seeking behaviors. Efforts to increase the disclosure of MST during screening should focus on reducing self-stigma. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30284857 TI - The role of common method variance in MMPI-2-RF response option augmentation. AB - Several studies have shown that response option augmentation (ROA), or increasing the number of response options of the Minnesota Multiphasic Personality Inventory (MMPI)-2-RF, improves the reliability of scale scores but does not improve convergent validity. However, these studies have not taken into account the response format of criterion measures, which may represent a form of common method variance (CMV). This study examined ROA with the MMPI-2-RF to determine whether number of response options is a source of CMV that may have affected previous estimates of convergent validity. The study used a repeated measures design with self-report and informant-report measures to examine differences between reliability and validity on scores from ROA and standard dichotomous MMPI 2-RF RC scales. Results replicate those of previous studies, suggesting that ROA with the MMPI-2-RF leads to small increases in internal consistency, but near zero gains in convergent validity. Results are unable to support the proposition that CMV, due either to respondent or number of response options, meaningfully inflates correlations between measures with identical number of response options. These results consistently showing no meaningful increase in convergent validity across several studies may have implications for test authors deciding on the number of response options. Limitations and future directions are also discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30284859 TI - Pain chronification and chronic pain impair a defensive behavior, but not the ability of acute pain to facilitate it, through the activation of an endogenous analgesia circuit. AB - The endogenous ability to decrease pain perception during life-threatening situations is crucial to the prevention of recuperative behaviors and to leave the subject free to engage in appropriated defensive responses. We have previously shown that acute pain activates the ascending nociceptive control-an endogenous analgesia circuit dependent on opioid mechanisms within nucleus accumbens-to facilitate the tonic immobility response, an innate defensive behavior. Now we asked whether chronic pain and pain chronification impairs either the tonic immobility response or the ability of acute pain to facilitate it by activating the ascending nociceptive control. We found a significant decrease in the duration of the tonic immobility response in rats during the induction and maintenance phases of the persistent mechanical hyperalgesia. This finding suggests that chronic pain and its development impair defensive responses. However, during the induction and maintenance phases of persistent hyperalgesia, the ascending nociceptive control activation, by a forepaw capsaicin injection, increased the tonic immobility response, an effect prevented by the blockade of MU-opioid receptors within nucleus accumbens. This finding suggests that pain chronification and chronic pain do not prevent the ability of acute pain to facilitate the defensive behavior of tonic immobility by activating the ascending nociceptive control. Therefore, although chronic pain states decrease the ability to engage in a defensive behavior, they may not prevent the expression of defensive behaviors during life-threatening situations accompanied by acute pain. The biological purpose of such a mechanism may be to increase the chances of survival of a wounded subject exposed to acute pain in a novel life threatening situation.

AB - Down-regulation of negative emotions has been shown to reliably inhibit the emotion-modulated startle reflex, but it remains unclear whether the timing of the startle probe influences the quantification of emotion regulation with this measure. Moreover, it is not known whether the degree of startle inhibition corresponds to the subjective attenuation of negative emotions. Therefore, the two main goals of the study were, first, to systematically analyze the effect of probe time on startle inhibition and, second, to explore the association between subjectively perceived down-regulation of arousal and valence and the degree of startle inhibition. We presented negative and neutral pictures to N = 47 participants. Pictures were paired with the instruction to reappraise or to maintain the emotions elicited by these pictures. Probes were delivered at three different times during a 12.5-s regulation phase, and the startle response was measured with electromyography. Valence and arousal ratings were assessed after each trial. Results revealed no significant impact of probe time on startle inhibition during reappraisal. Startle inhibition and perceived down-regulation of arousal were significantly and positively correlated, whereas perceived down regulation of valence was not. The results provide important implications for future studies in terms of startle probe timing and shed light onto the interpretation of startle inhibition as an indicator of subjective attenuation of negative emotions.

AB - Posttraumatic stress disorder (PTSD) is associated with elevated risk of both alcohol use disorder (AUD) and related conduct problems, which are associated with behavioral and emotional dysregulation. We conducted an intensive longitudinal burst design study with 10 weeks of experience sampling over the course of 1.5 years with 250 veterans of recent conflicts. We tested time-series models of daily associations between posttraumatic stress symptoms (PTSS), alcohol dependence syndrome, and conduct problems. Exacerbations of PTSS predicted higher dependence syndrome and conduct problems the next day. This effect was significant after controlling for both concurrent (i.e., same-day) associations between drinking and the outcomes as well as the strength of associations between the outcomes from one day to the next (i.e., autoregression). Affect lability and disinhibition were hypothesized vulnerability factors increasing the strength of within-person predictors of dependence syndrome and conduct problems. Lability and disinhibition were associated with greater dependence syndrome symptoms and conduct problems over the follow-up period. Consistent with expectation, lability rather than disinhibition increased the association between drinking and dependence syndrome as well as the strength of association between dependence syndrome symptoms from one day to the next. Moderating effects of disinhibition in the conduct problems model were not significant. Importantly, results indicated reciprocal associations over time. Lability potentiated the association between dependence syndrome symptoms and next day PTSS, whereas disinhibition potentiated the association between conduct problems and next day PTSS. Results demonstrate complex dynamic associations between PTSS, AUD symptoms, and conduct problems over time indicative of broad regulatory impairments.

AB - Although steroids are widely known to affect behavior through activation of nuclear/cytosolic receptors ("genomic" effects), steroids can also rapidly affect behavior via modulation of signal transduction pathways ("nongenomic," fast actions, or rapid effects). In zebra finches, there is evidence that sex steroids have context-specific effects on pair-maintenance behavior, on both acute and chronic timescales. Here, we quantified the effects of orally administered testosterone and 17beta-estradiol (E2) on pair-maintenance behavior. We show that E2 rapidly affects female, but not male, affiliative behavior profiles during a partner separation and reunion paradigm. More specifically, E2 rapidly (within 5 15 min of administration) increased females' spatial proximity to a partner. This effect was present regardless of breeding condition (water restriction or water ad libitum). Combined, these results contribute to a growing body of evidence implicating sex steroids in the regulation of prosocial behavior. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30284862 TI - Disassociating the relation between parents' math anxiety and children's math achievement: Long-term effects of a math app intervention. AB - Although parents' fears and worries about math-termed math anxiety-are negatively associated with their children's math achievement in early elementary school, access to an educational math app that 1st-grade children and parents use together can ameliorate this relation. Here we show that children of higher-math anxious parents learn less math during 1st-3rd grades, but this is not the case when families are given a math app (even after app use markedly decreases). Reducing the link between parents' math anxiety and their positive attitudes about math for their children helped to explain the sustained benefit of the math app. These findings indicate that interventions involving parents and children together can have powerful lasting effects on children's academic achievement and suggest that changes in parents' expectations for their children's potential for success in math, and the value they place on this success, play a role in these sustained effects.

AB - Despite the persistent gender gap in many organizational leadership positions, researchers have not yet examined objective predictors of this gap. A fully crossed 3 (Role Prime: leader, follower, control) * 2 (Gender Prime: present, absent) * 2 (Sex: male, female) experimental design examined the effect of group role (i.e., leader or follower) and gender on loss-aversion. Participants (192 total; 96 female) were asked to name either their former or current leader ("superior") or follower ("subordinate"), compared with a no prime condition. Results suggest that women primed with a follower role were more loss-averse than men primed with a follower role, and were more loss-averse than women primed with the leader role or in the control condition. However, the role prime did not affect men's loss-aversion. The current research suggests that researchers and practitioners should consider the effects of group role on loss-aversion, as this may contribute to gender gaps in the workplace.

AB - Routines in the family are a potential source of resilience for at-risk children and support children's emerging emotion regulation. Meanwhile, inadequate sleep has been linked with deficits in cognitive processes to attend to environmental stimuli and with poor emotion regulation for children. The detrimental effects of poor sleep are potentially worse in low-income children. The aim of the current study was to examine the moderating role of sleep in the association between family routines and emotion regulation in toddlers in poverty. We analyzed data of 130 toddlers (24-31 months; 58% boys) from low-income, primarily African American families. Mothers completed questionnaires about child routines (Child Routines Questionnaire; CRQ; Wittig, 2005).To measure emotion regulation, toddlers completed an observed behavioral task meant to elicit frustration (Lab TAB-Locomotor Version; Goldsmith & Rothbart, 1991). As hypothesized, adequate sleep (> 11 hr) fully moderated the association between routines and observed emotion regulation. There was no effect of routines on emotion regulation for toddlers with inadequate amounts of sleep. Analyses controlled for toddler respiratory sinus arrhythmia (RSA) as well as maternal emotion dysregulation (the Emotional Dysregulation Scale; EDS; Westen, Muderrisoglu, Fowler, Shedler, & Koren, 1997). These results emphasize the importance of sufficient sleep in at risk toddlers. Furthermore, the results suggest that the effectiveness of family interventions focusing on family health to increase toddler emotion regulation could be improved by incorporating sleep interventions/routines.

PMID- 30284866 TI - Exploring the relative importance of normative and distinctive organizational preferences as predictors of work attitudes. AB - Profile approaches to operationalizing person-organization (P-O) fit as the within-person correlation between an individual's ideal organization characteristics and their actual organization characteristics regularly find strong associations between P-O fit and an individual's work attitudes. However, profile correlation indices and other overall indices of P-O fit regularly confound normative and distinctive components of fit-that is: the extent to which the person's organization culture fits the culture that would be preferred by the average person, and the extent to which their organization fits an individual's idiosyncratic preferences. Here, we show how these two normative and distinctive P-O fits can be differentiated and related to an individual's attitudes about their organization experience. Utilizing data from 723 participants from four samples, we show that the degree to which an individual's description of their organizational culture corresponds to the normative ideal organizational culture may account for nearly all of the large associations regularly found between overall P-O fit indices and positive workplace attitudes. In contrast, the degree of fit between an individual's work environment and their distinctive or idiosyncratic preferences may play a relatively small role in predicting the positive workplace attitudes. We discuss broader implications for the design of organizational cultures and the more general understanding of the nature of P-O fit. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30284865 TI - Virtual reality analgesia for burn joint flexibility: A randomized controlled trial. AB - OBJECTIVE: We conducted a randomized controlled study to determine the effects of virtual reality (VR) distraction on pain and range of motion (ROM) in patients hospitalized for burn care during active physical therapy exercises. METHOD: Thirty-nine participants aged 15 to 66 (M = 36) years with significant burn injuries (mean burn size = 14% TBSA) participated. Under therapist supervision, using a within-subjects design, participants performed unassisted active ROM exercises both with and without VR distraction in a randomized order. Therapists provided participants with instructions but did not physically assist with stretches. Maximum active ROM was measured using a goniometer. A 0-100 Graphic Rating Scale (GRS) was used to assess the cognitive, affective, and sensory components of pain. A GRS rating of the amount of "fun" during stretching served as a measure of positive experience. RESULTS: Participants reported lower mean GRS ratings during VR, relative to No VR, for worst pain, pain unpleasantness, and time spent thinking about pain. They also reported having a more positive experience during VR than during No VR. However, patients did not show greater ROM during VR. CONCLUSION: Immersive VR reduced pain during ROM exercises that were under the control of the patient. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30284867 TI - Latent classes of PTSD symptoms in veterans undergoing residential PTSD treatment. AB - Although most veterans in the Department of Veterans Affairs (VA) health system are treated for posttraumatic stress disorder (PTSD) in the outpatient setting, the VA has approximately 40 residential PTSD treatment facilities across the country for those requiring more intensive care. The symptom profiles of these veterans are poorly understood. Thus, the current study was designed to characterize classes of PTSD symptoms in a national sample of veterans undergoing residential treatment. We analyzed latent classes of PTSD symptoms among 2,452 veterans entering VA PTSD residential treatment in fiscal year 2013. The model with the best fit was a 4-class model comprising a low symptom class, moderate symptom class with high reexperiencing symptoms, a moderate symptom class with high emotional numbing, and a high symptom class. Compared to classes identified in outpatient samples, these classes were similar in type but greater in severity. Classes differed by age, race/ethnicity, trauma type, co-occurring medical conditions, co-occurring psychiatric conditions, and social functioning. Compared to the moderate class with high emotional numbing, those in the moderate class with high reexperiencing symptoms were more likely to be non-White, have greater pain severity, greater sleep problems, and were less likely to be depressed. Our findings suggest that veterans in residential treatment who have more severe PTSD symptoms also experience other medical and psychosocial stressors. A better understanding of symptom profiles may help to create more individualized treatment planning and thus potentially improve care for these veterans.

AB - The generation effect is moderated by experimental design, as are a number of other encoding variables, such that the generation effect recall is typically larger in mixed-list than pure-list designs. In typical experiments on design effects, each study list is followed by its own recall test. Rowland, Littrell Baez, Sensenig, and DeLosh (2014) found that the testing effect was not moderated by experimental design using a procedures in which multiple study lists were followed by a single, end-of-session recall test over all lists. This may indicate an important difference between the testing effect and the set of effects (including generation) moderated by experimental design, or it may signal a more general limitation of design effects. Three experiments used the procedures of Rowland et al. and found that the generation effect was likewise unmoderated by experimental design: The generation effect was robust for pure lists and of equivalent size as with mixed lists. This was found for both a perceptual (letter transposition) and semantic (antonym) generation task. Along with prior research, these results constitute similarities between the generation and testing manipulations with respect to design effects and their limitations. This, in turn, implies a parallel between the mnemonic effects of retrieving information from semantic (generation effect) and episodic (testing effect) memory.

AB - An ongoing debate in the literature on language acquisition is whether preschool children process reference in an egocentric way or whether they spontaneously and by-default take their partner's perspective into account. The reported study implements a computerized referential task with a controlled trial presentation and simple verbal instructions. Contrary to the predictions of the partner specific view, entrained referential precedents give rise to faster processing for 3- and 5-year-old children, independently of whether the conversational partner is the same as in the lexical entrainment phase or not. Additionally, both age groups display a processing preference for the interaction with the same partner, be it for new or previously used referential descriptions. These results suggest that preschool children may adapt to their conversational partner; however, partner-specificity is encoded as low-level auditory-phonological priming rather than through inferences about a partner's perspective.

AB - One prominent feature of adaptive cognition in humans is the ability to flexibly adjust to changing task demands. In this respect, context-specific proportion congruency (CSPC) effects describe the phenomenon that participants learn to adapt to contexts of frequently occurring conflicts even when the upcoming context cannot be anticipated. Here, we aim to provide evidence that such CSPC effects strongly depend on the affective valence of the context. Participants had to categorize pictures as animals versus humans (Experiment 1), words as male versus female (Experiment 2), and food pictures as depicting cold or hot dishes/beverages (Experiment 3). Stimuli were laterally presented to the left or right, creating Simon-like response interference. Half of the stimuli were of positive valence, half of negative valence with valence always being task irrelevant. Positive or negative stimuli were associated with a high proportion of incongruent trials and a low proportion of congruent trials, respectively. In all three experiments, a CSPC effect was only significant when the high proportion of incongruent trials was associated with positive stimuli but reduced or even absent when the high proportion of incongruent trials was associated with negative stimuli. The findings further speak to the idea that it is the aversive nature of conflict stimuli that functions as a trigger for control adaptation. And such an unexpected aversive conflict signal looms larger when presented in a positive context than in a negative context. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30284871 TI - Development of loneliness in midlife and old age: Its nature and correlates. AB - Research has long demonstrated that loneliness is a key risk factor for poor health. However, less is known about the development and predictors of loneliness across later adulthood. We examined these questions using two-wave data obtained 5 years apart in the population-based Norwegian NorLAG study (N = 5,555; age 40 80 years; 51% women). We considered direct measures of loneliness (asking directly about feeling lonely) and indirect measures (avoiding the term loneliness) and linked them to self-report data on personality and contact with friends, and to register data on socioeconomic (education, income, unemployment), physical health (sick leave, lifetime history of disability), and social factors (children, marriage/cohabitation, lifetime history of divorce and widowhood). Results indicated that levels of loneliness increased steadily for women, whereas men's levels followed a U-shaped curve, with highest loneliness at ages 40 and 80. At age 40, loneliness declined between the two data waves, but with increasing age the decrease abated and turned into increases when loneliness was measured indirectly. Disability, no spouse/cohabiting partner, widowhood, and little contact with friends were each associated with more loneliness. Similarly, people high in emotional stability and extraversion reported less loneliness and experienced steeper loneliness declines on one or both loneliness measures. We take our results to illustrate the utility of combining self-report and register data and conclude that the development of loneliness across the second half of life is associated with both individual difference characteristics and aspects of social embedding. We discuss possible mechanisms underlying our findings and consider practical implications. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30284872 TI - The relationship between response consistency in picture naming and storage impairment in people with semantic variant primary progressive aphasia. AB - OBJECTIVE: The progressive loss of stored knowledge about word meanings in semantic variant primary progressive aphasia (svPPA) has been attributed to an amodal "storage" deficit of the semantic system. Performance consistency has been proposed to be a key characteristic of storage deficits but has not been examined in close detail and larger participant cohorts. METHOD: We assessed whether 10 people with svPPA showed consistency in picture naming across 3 closely consecutive sessions. We examined item-by-item consistency of naming accuracy and specific error types, while controlling for the effects of word-related variables such as word frequency, familiarity, and age of acquisition. RESULTS: Participants were very consistent in their accurate and inaccurate responses over and above any effects of the word-related variables. Analyses of error types that compared consistency of semantic errors, correct responses, and other error types (e.g., phonologically related errors, unrelated errors) revealed lower consistency. CONCLUSIONS: Our findings support the assumption that semantic features constituting semantic representations of objects are progressively lost in people with svPPA and are therefore consistently unavailable during naming. Variability in the production of error types occurs when distinctive features of an object are lost, resulting in the selection of semantically or visually similar items or in the failure to select an item and a response omission. The assessment of performance consistency sheds light on the underlying impairment of people with semantic deficits (semantic storage vs. access deficit). This can support the choice of an appropriate treatment technique to maintain or reteach semantic information. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30284873 TI - State anxiety predicts cognitive performance in patients with Parkinson's disease. AB - OBJECTIVE: Anxiety is common in Parkinson's disease (PD) and frequently a comorbidity that appears alongside nonmotor symptoms such as cognitive deficits; however, the relationship between anxiety and cognition in PD remains poorly understood. The aim of this study was to investigate the relationship between anxiety and specific cognitive domains (e.g., attention/working memory, executive functions, memory, language, and visuospatial function). METHOD: A total of 48 individuals with PD and 18 healthy controls were assessed using the State Trait Anxiety Inventory along with a comprehensive neuropsychological battery. Hierarchical multiple regression analysis was used to examine whether trait and/or state anxiety predicted deficits in overall cognitive function (Montreal Cognitive Assessment) and/or specific individual cognitive domains in the PD and healthy control samples while controlling for covariates such as age, depression (Geriatric Depression Scale), and Unified Parkinson's disease Rating Scale motor subsection-III (PD only). RESULTS: Results showed that state anxiety in PD significantly predicted performance across an array of cognitive domains, such as attention/working memory, executive functioning, memory, and language, whereas trait anxiety was a predictor only for executive functioning. In contrast, there was no significant relationship between state anxiety and visuospatial ability Conclusions: Overall, these findings highlight that performance in particular cognitive domains are associated with anxiety in PD. Thus, it may be critically important to consider and quantify the contribution of anxiety to cognitive performance when diagnosing and treating dementia and/or mild cognitive impairments in PD.

AB - OBJECTIVE: Two aspects of aphasic picture naming were examined: response consistency, that is, the extent to which the accuracy of the response to the same stimulus is replicated in a successive examination, and response predictability, that is, the extent to which accuracy depends on the characteristics of each stimulus. METHODS: Thirty-eight aphasic participants were examined twice. The response pattern was the same across the 2 presentations (response stability) for 36 participants, who were classified into 3 groups according to the prevailing error-type (lexical-semantic, phonological, or a balance between the two error-types): Their item-consistency was quantified with Cohen's kappa. In each case the roles played by lexical frequency, precocity of acquisition and length of the target word, and visual complexity and image agreement of the stimulus picture were examined; the ability to predict response accuracy of a model simultaneously including these 5 variables was quantified by means of the McFadden index. Finally, the relationship between predictability (McFadden index) and consistency (Cohen's kappa) was analyzed. RESULTS: For 34 of 36 participants, consistency was higher than chance. Consistency was directly correlated to the prevalence of lexical-semantic errors. On regression analysis, the relationship between consistency and predictability was significant. CONCLUSIONS: Response consistency reflects the existence of a clear difficulty gradient within the items of a battery. The significant relationship between consistency and error type suggests that, in principle, lexical-semantic errors might be more predictable than phonological errors based on the characteristics of each stimulus.

PMID- 30284875 TI - Cross-lagged relation of leisure activity participation to trail making test performance 6 years later: Differential patterns in old age and very old age. AB - OBJECTIVE: We investigated cross-lagged relations between leisure activity participation and Trail Making Test (TMT) performance over 6 years and whether those reciprocal associations differed between individuals. METHOD: We analyzed data from 232 participants tested on performance in TMT Parts A and B as well as interviewed on leisure activity participation in 2 waves 6 years apart. Mean age in the Wave 1 was 73.42 years. Participants were also tested on vocabulary (Mill Hill scale) as a proxy indicator of crystallized intelligence and reported information on early and midlife cognitive reserve markers (education and occupation). Latent cross-lagged models were applied to investigate potential reciprocal activity-TMT relationships. RESULTS: The relation of leisure activity participation predicting TMT performance 6 years later was significantly larger than was the relation of TMT performance predicting later leisure activity participation. Statistically comparing different moderator groups revealed that this pattern was evident both in individuals with low education and in those with high education but, notably, emerged in only young-old adults (but not in old-old adults), in individuals with a low cognitive level of job in midlife (but not in those with a high cognitive level of job in midlife), and in individuals with high scores in vocabulary (but not in those with low scores in vocabulary). CONCLUSIONS: Late-life leisure activity participation may predict later cognitive status in terms of TMT performance, but individuals may markedly differ with respect to such effects. Implications for current cognitive reserve and neuropsychological aging research are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30284876 TI - Spanish translation and validation of the Interpersonal Needs Questionnaire. AB - The present study reports the multistage development and evaluation of a Spanish translation of the Interpersonal Needs Questionnaire (INQ). The INQ measures the constructs of thwarted belongingness and perceived burdensomeness, which the interpersonal theory of suicide proposes are proximal causes of suicidal desire. Participants were bilingual Hispanic college students in the United States (n = 56), heritage Spanish-speaking college students in the United States (n = 281), college students in Spain (n = 1,016), psychiatric inpatients in Mexico (n = 181), college students in Mexico (n = 239), and Spanish-speaking U.S. adults (n = 104). Results indicated that a 9-item 2-factor solution (INQ-S-9) provided good fit. Multiple group analyses were also consistent with measurement invariance across nationalities and clinical severity. Finally, both subscale scores demonstrated good internal consistency, test-retest reliability, convergent validity, and concurrent associations with scores on measures of suicide ideation. Cultural considerations and implications for use in clinical and research settings are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30284878 TI - Long-term outcomes from a self-help smoking cessation randomized controlled trial. AB - There is a need for effective smoking cessation interventions that can be disseminated easily in health care and other settings. We previously reported that an extended self-help intervention comprising intensive repeated mailings over 18 months improved abstinence rates through 6 months beyond the end of the intervention when compared to both a reduced version of the self-help materials and a traditional self-help booklet. This report extends the follow-up for an additional 6 months (30-months postbaseline) to examine long-term maintenance of the intervention effect. We hypothesized that the previously observed "dose response" effect of treatment intensity would be maintained. Participants were randomized to Traditional Self-Help (TSH, n = 638), Standard Repeated Mailings (SRM, n = 614), or Intensive Repeated Mailings (IRM, n = 622). TSH received an existing self-help smoking cessation booklet. SRM received 8 cessation booklets mailed over 12 months. IRM received monthly mailings of 10 booklets and additional material to enhance social support over 18 months. Follow-up assessments occurred every 6 months through 30 months. Data were collected 2010 2013 and analyzed 2014-2017. At 1 year posttreatment, there was a linear dose effect with the highest abstinence rates observed in IRM (33%), followed by SRM (29%), and then TSH (23%; p = .002). Paired comparisons indicated that IRM was superior to TSH (p = .002). Results revealed a robust intervention effect for the intensive self-help intervention that was maintained 12 months after treatment completion. This further supports extended self-help as a low-cost intervention for smoking cessation. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30284877 TI - Changes in implicit alcohol attitudes across adolescence, and associations with emerging alcohol use: Testing the reciprocal determinism hypothesis. AB - Implicit alcohol-related cognitions develop during adolescence and are thought to play an important role in the etiology of adolescent alcohol use. Rooted in reciprocal determinism, a developmental theory of alcohol-related cognitions, the current study sought to enhance our understanding of the development of automatic alcohol associations and their relationship with alcohol use. To provide a theoretically aligned test of reciprocal determinism, we used latent change score models to examine whether growth in automatic alcohol associations and alcohol use was related to each other (between-person effects) and whether each construct led to changes in the other over time (within-person effects). Adolescents (N = 378) completed 4 annual assessments, spanning early to middle adolescence. Automatic alcohol associations were assessed with a Single Category Implicit Association Test, and we used a quadruple processing tree model to extract a more "process pure" index of these associations. Alcohol use increased from early to middle adolescence, as negative automatic alcohol associations weakened over that same time period. Although there was no support for between-person associations, on the within-person level, weak negative automatic alcohol associations at Waves 2 and 3 were associated with increases in drinking at subsequent waves. Alcohol use did not significantly predict changes in automatic alcohol associations. Findings suggest the utility of distinguishing within- and between-person associations to understand the development of automatic alcohol associations and that automatic alcohol associations are prospectively associated with alcohol use and a potential target for intervention, one that becomes an increasingly salient influence on drinking as adolescence progresses.

AB - Heavy drinking among college students in the United States is common and results in a wide range of problems. Symptoms of depression are also common among college students and may exacerbate problems associated with heavy drinking, but to date most studies have been cross sectional and relied on an aggregate measure of alcohol problems. Further, depressive symptoms may also predict other elements of risk among heavy drinkers, including greater experience of substance-related reinforcement, and diminished experience of substance-free reinforcement. The current study examines depressive symptoms as a prospective predictor of changes in alcohol problem domains and reward variables in a sample of heavy drinking college students. Heavy drinking college students (N = 138) completed a survey assessing depressive symptoms, alcohol problems, and reinforcement at baseline and after a 12-month follow-up period. Multiple regressions examined the utility of depressive symptoms (DASS-21) in predicting alcohol problems, substance related reinforcement, and substance-free reinforcement at the 12-month follow-up after controlling for baseline drinking level and the baseline level of the relevant outcome variable. Baseline depressive symptoms predicted 12-month alcohol problems related to impaired control (i.e., drinking more than planned), self-perception, and self-care. Depressive symptoms also predicted lower 12-month substance-free, but not substance-related, reinforcement. Finally, change in depressive symptoms was associated with total alcohol problems, impaired control, self-perception, self-care, academic/occupational, and physiological dependence problems at 12-month follow-up. Heavy drinkers with depressive symptoms may benefit from interventions targeting alcohol problems that also increase access to and engagement in rewarding alternative activities.

PMID- 30284880 TI - Trajectories of positive and negative affect across the transition to college: The role of daily interactions with parents and friends. AB - The college transition is uniquely challenging for many first-year students. Few studies have investigated developmental change in students' adjustment across this brief, but significant transition, nor the daily interpersonal dynamics that are associated with adjustment across this same time. Guided by ecological and stage-environment fit frameworks, this study examined trajectories of first-year students' positive and negative affect across the transition to college. Further, we examined daily interactions with parents and friends as predictors of these trajectories. Participants were 146 first-year college students from a large southwestern university entering their first semester of college (Mage = 17.82, SD = 0.50). Electronic ecological momentary assessments (EMAs) were administered to students twice weekly (maximum 49 observations) from July to December to assess daily experiences during the transition to college and across the first semester. Multilevel growth analyses showed that students reported a meaningful decrease in positive affect across the first semester, but stable levels of negative affect. Involvement and conflict with parents and friends predicted variability in these average changes, as well as daily affective states. As expected, greater involvement with parents and friends was associated with greater positive and less negative affect, and reports of conflict with parents and friends predicted negative affect experiences. Together, these findings suggest the importance of support from parents and friends during the initial adaptation to college, as well as the potential undermining role of conflict with significant others.

PMID- 30284881 TI - Patterns of parental emotion-related discourse and links with children's problem behaviors: A person-centered approach. AB - Research demonstrates that parents' emotion-related discourse during reminiscing shapes children's psychosocial outcomes, yet little is known about how different forms of parental emotion-related discourse work in combination. The present study takes a person-centered approach to better understand the relation of multiple forms of parental emotion discourse during reminiscing with problem behaviors in early childhood, as well as child influences on parents' emotion discourse during reminiscing. Specifically, we simultaneously examine three forms of parents' emotion-related discourse (emotion coaching and dismissing, emotion explanations, and elaboration) using cluster analysis to determine parents' patterns of these three discourse forms during discussion about past events. Parents and their preschool-aged children (n = 154) completed a parent-child reminiscing task. Transcripts were coded for emotion coaching and dismissing, emotion explanations, and elaboration. Parents reported on children's internalizing and externalizing behaviors, temperament, and gender, and children completed a language assessment. Cluster analyses revealed three parental discourse patterns: elaboration/negative emotion emphasis, positive and negative emotion emphasis, and low emotion discourse. Children's receptive language was associated with parents' membership in the low emotion discourse cluster. Children's temperament and gender were unrelated to parental emotion-related discourse patterns. Parents in the positive and negative emotion emphasis cluster had children with fewer internalizing behaviors compared to both other clusters, and parents in the elaboration/negative emotion emphasis cluster had children with more internalizing behaviors compared to both other clusters. Findings support the utility of a person-centered approach in providing a holistic view of parents' use of multiple emotion socialization strategies during reminiscing.

AB - Learning always happens from input that contains multiple structures and multiple sources of variability. Though infants possess learning mechanisms to locate structure in the world, lab-based experiments have rarely probed how infants contend with input that contains many different structures and cues. Two experiments explored infants' use of two naturally occurring sources of variability-different sounds and different people-to detect regularities in language. Monolingual infants (9-10 months) heard a male and female talker produce two different speech streams, one of which followed a deterministic pattern (e.g., AAB, le-le-di) and one of which did not. For half of the infants, each speaker produced only one of the streams; for the other half of the infants, each speaker produced 50% of each stream. In Experiment 1, each stream consisted of distinct sounds, and infants successfully demonstrated learning regardless of the correspondence between speaker and stream. In Experiment 2, each stream consisted of the same sounds, and infants failed to show learning, even when speakers provided a perfect cue for separating each stream. Thus, monolingual infants can learn in the presence of multiple speech streams, but these experiments suggest that infants may rely more on sound-based rather than speaker based distinctions when breaking into the structure of incoming information. This selective use of some cues over others highlights infants' ability to adaptively focus on distinctions that are most likely to be useful as they sort through their inherently multidimensional surroundings.

AB - Secrets carry valuable social information. Because the content of secrets can be damaging to the secret-keeper's reputation, people should only disclose their secrets to people whom they trust. Therefore, tracking which people know each other's secrets can be used as cue of social relationships: If one person tells another person a secret, those people are likely friends. Here, in 5 studies with 3- to 12-year-old children (total N = 452), we examined the developmental trajectory of reasoning about secret sharing as an indication of third-party friendship. By age 6, but not before, children expected that a person would be friends with someone that she told a secret. We replicated this main finding across four studies by comparing secret sharing to other cues of affiliation. Children treated sharing a secret as a stronger cue to friendship than sharing a physical object (Study 1), sharing a fact (Studies 2-4), or sharing membership on the same sports team (Study 3). Although younger children did not understand that secret sharing indicated friendship, they did expect people to be more likely to disclose their secrets to friends than to nonfriends (Study 5). Taken together, our results indicate that children understand the social significance of sharing secrets and use secret sharing to make important predictions about the social world. Specifically, children infer social relationships based on which people know each other's secrets and expect others to share secrets selectivity with friends.

AB - Emotional reactions to peer victimization may increase risk for subsequent peer victimization. In the present study, we investigated whether shame mediated the development of chronic peer victimization, i.e., young people's experiences of being bullied persistently across time. We used a multiple mediation model to test the indirect effects of Time-1 victimization on Time-3 victimization (1 year later) through 4 Time-2 shame-related variables (characterological, bodily, and behavioral shame; shame proneness) for 396 youth (10-13 years of age). The total indirect effect of Time-1 victimization on Time-3 victimization through the 4 shame-related mediators was statistically significant. Analyses revealed specific indirect positive effects for bodily shame and shame proneness. Findings suggest that shame may be an emotional mechanism underlying chronic peer victimization.

PMID- 30284883 TI - Family nurture intervention for preterm infants facilitates positive mother infant face-to-face engagement at 4 months. AB - Although preterm infants are at risk for social deficits, interventions to improve mother-infant interaction in the neonatal intensive care unit (NICU) are not part of standard care (SC). Study participants were a subset from a randomized controlled trial of a new intervention for premature infants, the Family Nurture Intervention (FNI), designed to help mothers and infants establish an emotional connection. At infants' 4 months corrected age, mother-infant face to-face interaction was filmed and coded on a 1-s time base for mother touch, infant vocal affect, mother gaze, and infant gaze. Time-series models assessed self- and interactive contingency. Comparing FNI to SC dyads, FNI mothers showed more touch and calmer touch patterns, and FNI infants showed more angry-protest but less cry. In maternal touch self-contingency, FNI mothers were more likely to sustain positive touch and to repair moments of negative touch by transitioning to positive touch. In maternal touch interactive contingency, when infants looked at mothers, FNI mothers were likely to respond with more positive touch. In infant vocal affect self-contingency, FNI infants were more likely to sustain positive vocal affect and to transition from negative to positive vocal affect. In maternal gaze interactive contingency, following infants' looking at mother, FNI mothers of male infants were more likely to look at their sons. In maternal gaze self-contingency, following mothers' looking away, FNI mothers of male infants were more likely to look at their sons. Documentation of positive effects of the FNI for 4-month mother-infant face-to-face communication is useful clinically and has important implications for an improved developmental trajectory of these infants.

AB - School-based professionals often use curriculum-based measurement of reading (CBM R) to monitor the progress of students with reading difficulties. Much of the extant CBM-R progress monitoring research has focused on its use for making group level decisions, and less is known about using CBM-R to make decisions at the individual level. To inform the administration and use of CBM-R progress monitoring data, the current study evaluated the utility of 4 progress monitoring schedules that differed in frequency (once or twice weekly) and density (1 or 3 probes). Participants included 79 students (43% female; 51% White, 25% Hispanic or Latino, 11% Black or African American, 1% other, 12% unknown) in Grades 2 (n = 45) and 4 (n = 34) who were monitored across 10 weeks (February to May). Consistent with a focus on individual-level decision making, we used regression and mixed-factorial analysis of variances (ANOVAs) to evaluate the effect of progress monitoring schedule frequency, schedule density, grade level, and their interaction effects on CBM-R intercept, slope, SE of the slope (SEb), and SE of the estimate (SEE). Results revealed that (a) progress monitoring schedule frequency and density influenced the magnitude of SEb, (b) density had a significant but negligible impact on SEE, and (c) grade level had a significant effect on slope and intercept. None of the interaction effects were statistically significant. Findings from this study have implications for practitioners and researchers aiming to monitor students' progress with CBM-R.

AB - Implementation science provides guidance on adapting existing evidence based practices (EBPs) by incorporating implementation concerns from the start. Focus group methodology was used to understand barriers and facilitators of transition planning and implementation for students with autism spectrum disorder (ASD) who often experience disparate postsecondary outcomes compared to peers. Results were used to modify an evidence-based consultation intervention originally applied to young students with ASD, called the Collaborative Model for Promoting Competence and Success (COMPASS; Ruble, Dalrymple, & McGrew, 2012). Because consultation is a multilevel EBP, two existing implementation science frameworks were used to guide adaptation: the Framework for Evidence Based Implementation and Intervention Practices (Dunst & Trivette, 2012) and the Consolidated Framework for Implementation Research (Damschroder et al., 2009). The purpose of this article is to describe a process of adaptation of COMPASS that may be useful for other implementation science studies of consultation interventions, teacher acceptability, feasibility, and burden, and parent/student satisfaction with the adapted intervention.

AB - School satisfaction is a critical aspect of well-being for every child and adolescent. Yet studies have rarely investigated whether school satisfaction varies depending upon participant characteristics and school-related social factors. Here we investigated whether disability and gender moderate adolescents' self-report of school satisfaction. We also explored the role of mediating variables such as teacher support, parent support, and relationships with peers (including friendships and also bullying). Our analysis of data from 3,830 adolescents revealed a significant interaction between disability and gender. Girls with disabilities reported the lowest school satisfaction, an effect that appeared to be more strongly mediated by perceived lack of teacher support than other variables. Our findings are novel in disaggregating school satisfaction data by both disability and gender to reveal an interaction between these variables and in investigating the role of mediating variables relating to school related social factors.

AB - Single-case experimental methods are used across a range of educational and psychological research. Single-case data are analyzed with a variety of methods, but no statistic has demonstrated clear superiority over other methods. The time series nature of single-case designs requires special consideration for baseline trend and autocorrelation when estimating intervention effect size. However, standard correction methods are limited because they assume precise statistical estimation of trend and autocorrelation. Unlike standard correction methods, Monte Carlo simulation methods can address the poor precision of single-case effect size indices. This paper presents the rationale for a new simulation method, Interrupted Time-Series Simulation (ITSSIM). A small field test was also conducted, and ITSSIM performed similarly to sophisticated multilevel methods for single-case research. ITSSIM is accessible as a free software application that requires no prior knowledge of statistical computing or syntax. ITSSIM may be used to estimate the effect size of a single interrupted time-series (AB design), and multiple ITSSIM effect size estimates may be combined via meta-analysis.

AB - In the present study, we sought to examine response trajectories to brief (11 week) school-based homework interventions and factors that may help schools predict responses. Participants included 222 middle-school students (72% boys; Mage = 12.00 years, SD = 1.02) who had been diagnosed with attention deficit/hyperactivity disorder (ADHD) and had received either a contingency management or skills-based intervention for homework problems. Both interventions included 16 20-min student meetings with a school counselor and two parent meetings. Trajectories of response for ratings of homework problems and assignment completion were examined from baseline to a 6-month follow-up using growth-mixture models. Baseline variables routinely measured in school settings, including grade-point average (GPA), math and reading achievement, and externalizing and internalizing symptoms, were examined as predictors of treatment-response trajectories. The majority of students (68-81%) showed positive treatment response across outcomes. However, trajectories of students who did not respond to intervention were identified for each outcome. Baseline GPA significantly predicted trajectories for all outcomes and achievement scores significantly predicted trajectories of teacher-reported homework performance and parent-reported homework problems, such that youth with relatively higher baseline GPAs and achievement were most likely to respond. In contrast, neither externalizing nor internalizing symptoms were significant predictors of response trajectories. Schools can use GPA and academic-achievement data to determine whether brief school-based interventions for homework problems are likely to succeed. Students with ADHD who display severe academic impairment (i.e., GPA lower than 2.0 at baseline) may benefit from a more long-term, intensive intervention.

PMID- 30284893 TI - A framework for disentangling the hyperbolic truth of neurofeedback: Comment on Thibault and Raz (2017). AB - In this comment, we propose a theoretical framework for disentangling the potentially multiple elements driving the effects of electroencephalogram (EEG) neurofeedback (EEG-nf) to clarify the roadmap for research in the field. Three questions are identified: (a) Do EEG-nf effects originate from a placebo effect related to the technological environment of a neurofeedback session? (b) Do EEG nf effects originate from a nonspecific effect of cognitive brain training during neurofeedback? If so, a cognitive training would be underpinned by the brain activity regulation loop but this training would not be specifically related to the neurophysiological biomarker chosen. (c) Do EEG-nf effects originate from a specific effect of cognitive brain training? If so, the effects of EEG-nf would be explained by the training of the specific neurophysiological biomarker chosen, depending on the pathophysiological mechanism(s) of the disorder. The proposed framework might thus allow to understand to what degree each of these level contribute to the effects of EEG-nf on the brain and behavior in view of the psychosocial variables involved.

Following a review of extant reporting standards for scientific publication, and reviewing 10 years of experience since publication of the first set of reporting standards by the American Psychological Association (APA; APA Publications and Communications Board Working Group on Journal Article Reporting Standards, 2008), the APA Working Group on Quantitative Research Reporting Standards recommended some modifications to the original standards. Examples of modifications include division of hypotheses, analyses, and conclusions into 3 groupings (primary, secondary, and exploratory) and some changes to the section on meta-analysis. Several new modules are included that report standards for observational studies, clinical trials, longitudinal studies, replication studies, and N-of-1 studies. In addition, standards for analytic methods with unique characteristics and output (structural equation modeling and Bayesian analysis) are included. These proposals were accepted by the Publications and Communications Board of APA and supersede the standards included in the 6th edition of the Publication Manual of the American Psychological Association (APA, 2010).

AB - The congenital dilation of the bile duct is an infrequent pathology in western countries and is associated with the female sex. It is usually diagnosed clinically with complementary tests and evaluated at an early age and also appears frequently in adults. These dilatations are grouped into five types according to Todani's classification, including type Ic (Figure 1). The treatment of choice for dilatations of the biliary duct Todani type I is the complete excision of the biliary tract due to the susceptibility of malignant degeneration. A reconstruction is performed via a hepaticojejunostomy with a Roux en-Y loop. Although in non-malignant cases, a papillotomy with prophylactic stent placement using ERCP can be performed as an alternative. We present the case of a 54-year-old female with a history of high blood pressure, she was examined due to generalized abdominal pain which was unrelated to food intake. The blood test did not identify any alterations of interest. Ultrasound identified a fusiform dilation of the common bile duct occupied by lithiasis. ERCP was attempted due to choledocholithiasis, but the procedure was abandoned as it was not feasible to channel the duodenal papilla. The study was completed with NMR cholangiography (transverse plane [Figure 2] and coronal plane [Figure 3]), identifying a diffuse fusiform dilatation of the common bile duct and common hepatic duct, compatible with congenital cystic lesion Todani type Ic. Finally, the patient underwent a hepaticojejunostomy after sectioning of the main bile duct and extraction of choledocholithiasis.

AB - INTRODUCTION AND AIM: Crohn's disease (CD) is a form of inflammatory bowel disease and is mainly characterized by diarrhea and abdominal pain. The aim of our study was to analyze the usefulness of performing a 75SeHCAT scan in CD patients with chronic diarrhea and suspected bile acid malabsorption (BAM). In addition, we aimed to determine whether there was a relationship with the clinical features of the disease and a previous bowel resection. PATIENTS AND METHODS: this was an observational cross-sectional study of 39 patients with a diagnosis of CD and chronic diarrhea. All cases underwent a 75SeHCAT scan for BAM diagnosis, after discarding disease activity. RESULTS: the study cohort included 19 females and 20 males. The median age was 44 years and the majority of patients were A2 L1 B1 according to the Montreal classification; 84.6% of patients had undergone a previous bowel resection. BAM was present in 97.4% of patients (100% and 83.3% of patients with and without previous surgery, respectively), which was severe in 92.1% of cases. Treatment with bile acid sequestrants was initiated and a favorable response was obtained in 72.2% of patients. The relationship between BAM degree (moderate or severe), bowel surgery and the response to bile acid sequestrant treatment was also analyzed but not statistically significant. CONCLUSION: BAM is a frequent cause of diarrhea in CD patients in endoscopic or radiological remission. This condition was present in all patients with a history of a bowel resection. A response to bile acid sequestrants treatment was observed in 73% of patients. PMID- 30284904 TI - Treatment of graft-versus-host disease with mesenchymal cells as a complication of a liver transplantation. AB - We present the case of a liver transplant (LT) recipient donor who developed graft versus host disease (GVHD). The main features were cutaneous rash, diarrhea and pancytopenia. Mesenchymal cells were administered as part of the treatment. This is the first case of a patient with GVHD after LT reported to date. Despite the treatment, there was no improvement in aplasia or gastrointestinal symptoms and the patient died due to a disseminated infection. PMID- 30284905 TI - Colorectal cancer screening and survival. AB - It is difficult to resist the undeniable allure of screening as a means to diagnose common, potentially serious diseases before their natural history reaches an incurable stage. Colorectal cancer (CRC) is a classical example where the benefits seem to be within reach: we have technologies available that allow its diagnosis before symptoms or signs develop, at a reasonable cost, and using methods acceptable by a significant percentage of the population. PMID- 30284906 TI - Comparison of long course and short course preoperative radiotherapy in the treatment of locally advanced rectal cancer: a systematic review and meta analysis. AB - BACKGROUND: rectal cancer (RC) is one of the most prevalent malignancies worldwide and different preoperative radiotherapies may lead to different outcomes. This meta-analysis aimed to compare the effectiveness of long-course (LC) and short-course radiotherapy (SC), with or without chemotherapy, for locally advanced rectal cancer. METHODS: studies published up to March 31st 2018 were retrieved from PubMed, Medline, Cochrane and EMABSE. Randomized control or consort control trials that reported the outcomes of short or long course radiotherapy were eligible. Either a fixed or random effects model was used to access the overall combined risk estimates. RESULTS: sixteen studies with a total of 2,773 RC patients were included in the analysis. There were no significant differences between LC and SC therapies with regard to the following: pathological complete response (PCR) (I2 = 78%, p < 0.05, RR = 0.54, 95% CI: 0.26 1.10); tumor downstaging (I2 = 79%, p < 0.05, RR = 0.83, 95% CI: 0.58-1.17); local recurrences (I2 = 22%, p = 0.27, RR = 0.55, 95% CI: 0.26-1.16); distant metastases (I2 = 29%, p = 0.22, RR = 1.03, 95% CI: 0.77-1.37); mortality (I2 = 0%, p = 0.78, RR = 0.95, 95% CI: 0.78-1.15) and serious late toxicity (I2 = 74%, p = 0.01, RR = 1.10, 95% CI: 0.37-3.26). In the subgroup analysis, LC had a better PCR and tumor downstaging rate compared with SC in the RCT subgroup. Besides, LC also presented a better PCR rate compared with SC without chemotherapy. CONCLUSIONS: LC and SC are both effective in the preoperative treatment of RC with regard to PCR, tumor downstaging, local recurrences, distant metastases, mortality and serious late toxicity. Furthermore, chemotherapy may enhance the efficacy of preoperative treatment. PMID- 30284907 TI - A rare case of acute obstructive suppurative pancreatic ductitis associated with ERCP. AB - A 76-year-old male with severe abdominal pain and a high fever was admitted to our hospital. The patient underwent a therapeutic endoscopic retrograde Cholangiopancreatography (ERCP) procedure one month previously due to acute biliary pancreatitis and a plastic biliary stent (8.5F) was placed. A follow-up computed tomography (CT) scan identified a huge cyst lesion in the body of pancreas, which was initially misdiagnosed as a pseudocyst. The patient progressed to severe sepsis and septic shock soon after admission. PMID- 30284908 TI - Vitamin D deficiency in outpatients with inflammatory bowel disease: prevalence and association with clinical-biological activity. AB - INTRODUCTION: there are few data on the prevalence of vitamin D deficiency in patients with inflammatory bowel disease (IBD) in Spain. A deficiency could be associated with a worse course of the disease. AIM: to determine the prevalence of 25-hydroxyvitamin D (25OHD) deficiency in a cohort of outpatients with IBD and assess its association with clinical and biological activity, quality of life and psychological symptoms. METHODS: a cross-sectional, single-center observational study was performed. The study variables were obtained via clinical interviews, medical chart review and validated questionnaires (Hospital Anxiety and Depression Scale and Short Quality of Life in Inflammatory Bowel Disease Questionnaire). 25OHD was measured in the same laboratory by an electro chemiluminescence immunoassay. RESULTS: the study included 224 patients. The prevalence of vitamin D deficiency in Crohn's disease and ulcerative colitis was 33.3% and 20.3%, respectively. In Crohn's disease, vitamin D deficiency was associated with a higher clinical activity (p < 0.001) and a higher concentration of fecal calprotectin (p = 0.01). In ulcerative colitis, it was associated with clinical activity (p < 0.001), the use of steroids during the last six months (p = 0.001) and hospital admission during the previous year (p = 0.003). A sub analysis of 149 patients failed to detect an association between vitamin D and quality of life or the scores of the Hospital Anxiety and Depression Scale. CONCLUSIONS: vitamin D deficiency is common in patients with inflammatory bowel disease. An association was found between vitamin D concentration and clinical activity indexes, as well as fecal calprotectin levels in Crohn's disease. PMID- 30284909 TI - Apparent diffusion coefficient and enhancement patterns in MR imaging as markers of severe or moderate ileum inflammation in Crohn's disease. AB - BACKGROUND AND PURPOSE: magnetic resonance enterography has been increasingly used for the diagnosis and follow-up of Crohn's disease (CD). The purpose of the study was to compare the apparent diffusion coefficient (ADC) with wall enhancement for the differentiation of severe, moderate or no inflammation activity in the ileum. METHODS: a prospective, blinded study was conducted of 46 CD patients with a clinical Crohn's disease activity index (CDAI) >= 220 and a simple endoscopic score for Crohn's disease (ES-CD) >= 7, which yielded 58 inflamed segments with CD. Twenty controls were also included. All segments were characterized by four ADC readings. The two different enhancement patterns observed in inflamed segments, transmural or mucosal, were associated with severely (23) or moderately (35) active CD. RESULTS: the ADC value decreased from 2.79 +/- 0.35 x 10-3 mm2/s for normal segments to 1.81 +/- 0.39 x 10-3 mm2/s for the moderately inflamed segments and 1.15 +/- 0.20 x 10-3 mm2/s for severely inflamed segments (p <= 0.0001). ROC curve analysis on the basis of the three ADC distributions showed a very good discrimination capability with an area under the curve of 0.95. Three groups were defined as follows: normal ileum ADC > 2.4 x 10 3 mm2/s, moderate stages of inflammation 1.5 x 10-3 mm2/s < ADC <= 2.4 x 10-3 mm2/s and severe stages of ADC <= 1.5 x 10-3 mm2/s. CONCLUSIONS: the ADC value reliably discriminates between normal and inflamed ileum and also distinguishes between severe and moderate inflammation. PMID- 30284910 TI - Delayed gastric emptying following pancreatoduodenectomy: a Roux-en-Y gastrojejunostomy vs Billroth II gastrojejunostomy randomized study. AB - INTRODUCTION: delayed gastric emptying (DGE) is the most common complication after pancreaticoduodenectomy (PD) and it occurs in 50% of cases. OBJECTIVES: the endpoint was to determine if there were any differences in the incidence of DGE between Roux-en-Y gastrojejunostomy (ReY) and Billroth II gastrojejunostomy (BII) in PD with pancreaticogastrostomy (PG). METHODS: this was a case-control prospective randomized study of all PD cases between 2013 and 2016. Sixty-four patients were included, 32 in each group. An intention-to-treat statistical analysis was performed. RESULTS: no significant differences were found with regard to morbidity and mortality or hospital stay. DGE was present in 25% of the patients in the BII group in comparison to 15.6% in the ReY group, which was not statistically significant (p = 0.35). There was a higher percentage of patients with primary DGE in the BII group, 12.5% versus 6.2%, but this was not statistically significant (p = 0.53). No difference in DGE severity was observed. Male gender (OR 8.38 [1.1; 129]), abdominal complications (OR 15 [1.7; 396.9]), pre-operative malnutrition (OR 99.7 [3.3, 11,126]) and hemorrhage (OR 9.4 [1.37, 107.94]) were the main risk factors for DGE according to the multivariate analysis. CONCLUSIONS: there were no significant differences in the incidence or severity of DGE between BII or ReY after PD with PG. PMID- 30284911 TI - Algorithms to facilitate shared decision making for the management of mild-to moderate ulcerative colitis. AB - INTRODUCTION: Non-adherence has been a key barrier to the efficacy of medical treatments in ulcerative colitis (UC). Engaging patients in their IBD care via shared decision making (SDM) to facilitate self-management may improve adherence to therapy. Areas covered: This review aims to summarize the most recent trial evidence from 2012-2017 for mild-to-moderate UC in order to develop clinical algorithms that guide SDM to facilitate self-management. A structured literature search via multiple electronic databases was performed using the search terms 'ulcerative colitis,' 'treatment,' 'management,' 'medication,' 'maintenance,' 'remission,' '5-ASA,' and 'inflammatory bowel disease. Expert commentary: Novel formulations of existing oral and topical medications have expanded the treatment options available for the induction and maintenance therapy for mild-to-moderate UC. Daily dosing of 5-ASA therapy is equivalent to twice daily dosing. The combination therapies of oral plus topical 5-ASA therapy and 5-ASA plus corticosteroid therapy are more effective than monotherapy. Budesonide MMX now plays a role in the management of mild-to-moderate UC. This review collates the evidence on drug efficacy and safety, adherence and tolerability, and non invasive monitoring of mild-to-moderate UC into SDM-orientated algorithms to facilitate self-management. PMID- 30284912 TI - Characteristics, diagnoses, illness course and risk profiles of inpatients admitted for at least 21 days to an Australian private psychiatric hospital. AB - OBJECTIVES: To perform a clinical and risk audit of private hospital inpatients staying in hospital at least 21 days. METHODS: Of 492 admissions for >=21 days in 2016, 40 were randomly selected for audit. Characteristics, illness severity and course using the Clinical Global Impression severity (CGI-S) subscale and improvement (CGI-I) subscale, and clinical risk profiles were ascertained at admission, day 15 and discharge by two psychiatrists. RESULTS: The cases were 65% female, age 50.0+/-16.2 years (range 24-86), 43% in relationships, and 28% on disability support. The length of stay was 29+/-7 days. On admission 88% were severely or markedly ill on the CGI-S subscale. Thirty-nine of 40 cases had >=3 psychiatric diagnoses: 93% depression, 48% bipolar, 15% schizophrenia. High risk was present in suicide risk (48%), illness-induced dysfunction risk (78%) and physical risk (28%). By day 15, 63% were not improved or marginally worse. Suicide ratings were unimproved. By the time of discharge, illness severity and risk ratings were significantly reduced. CONCLUSION: Private hospital inpatients staying >=21 days were predominantly female and had severe, diagnostically complex illnesses and high risk ratings. Most were still seriously unwell after 15 days. Patients improved significantly by the time of discharge (though were by no means recovered), indicating that the duration of hospitalisation was appropriate. PMID- 30284914 TI - Australia's 'Better Access' scheme: Has it had an impact on population mental health? AB - BACKGROUND:: Australia introduced the Better Access scheme in late 2006, which resulted in a large increase in the provision of mental health services by general practitioners (GPs), clinical psychologists, other psychologists and allied health professionals. It is unknown whether this increase in services has had an effect on the mental health of the population. METHODS:: The following data were examined: per capita use of mental health services provided by GPs, clinical psychologists, other psychologists, allied health professionals and psychiatrists from 2006 to 2015 according to the Australian Government Department of Human Services; prevalence of psychological distress in adults (as measured by the K10) from National Health Surveys in 2001, 2004-2005, 2007-2008, 2011-2012 and 2014-2015; and the annual suicide rate from 2001 to 2015 according to the Australian Bureau of Statistics. RESULTS:: The large increase in the use of mental health services after the introduction of the Better Access scheme had no detectable effect on the prevalence of very high psychological distress or the suicide rate. CONCLUSION:: Better Access has not had a detectable effect on the mental health of the Australian population. PMID- 30284913 TI - Retrospective analysis of effects of sodium-glucose co-transporter 2 inhibitor in Japanese type 2 diabetes mellitus patients with chronic kidney disease. AB - AIM: The aim of this study was to assess the renal effects of the glucose lowering SGLT2 inhibitors in Japanese type 2 diabetes mellitus patients with chronic kidney disease. METHODS: The Kanagawa Physicians Association maintains a registry of patients who visit their 31 clinics. Clinical data of type 2 diabetes mellitus patients with chronic kidney disease, who were prescribed SGLT2 inhibitors in addition to other treatments, were collected and analysed. RESULTS: SGLT2i was associated with a fall in HbA1c from 64.1 +/- 16.7 mmol/mol (8.0 +/- 1.5%) to 56.5 +/- 12.9 mmol/mol (7.3 +/- 1.2%) ( p < 0.01) in 869 analysed cases, a decrease in urine albumin-creatinine ratio from a median of 47.1 to 41.1 mg/gCr, and decrease in estimated glomerular filtration rate from 77.7 +/- 23.9 to 75.0 +/- 23.9 mL/min/1.73 m2 ( p < 0.01). The effect on albumin-creatinine ratio was independent of age or stage of estimated glomerular filtration; however, there was a significant negative correlation between albumin-creatinine ratio at the initiation of SGLT2 inhibitor and change in ACR. Multiple linear regression analysis identified use of empagliflozin, beta-blockers, and sulphonylureas, Deltasystolic blood pressure at office, serum Cr and albumin creatinine ratio value at initiation of SGLT2 inhibitor as independent and significant determinants of change in ACR. CONCLUSIONS: This study confirmed that the beneficial renal effects of SGLT2 inhibitor in Japanese type 2 diabetes mellitus patients with chronic kidney disease, similar to those reported in large scale clinical trials conducted in Western countries. PMID- 30284915 TI - A cost-benefit analysis of the Improving Access to Psychological Therapies programme using its key defining outcomes. AB - The economic argument underpinning the Improving Access to Psychological Therapy programme has been a central component in its initial and continued investment. Using open-access data, this article undertook a cost-benefit analysis using the programme's key defining outcomes to determine its return-on-investment. It was found that in terms of investment and efficiency gains, the programme was in the higher ends of the cost spectrum for delivering psychological therapies. Although cost-estimates appear promising at first, when set in the context of a lower number of treatment contacts and a high proportion of early disengagement, estimates increased sharply. PMID- 30284916 TI - Antibiotic activity of the antioxidant drink effective Microorganism-X (EM-X) extracts against common nosocomial pathogens: an in vitro study. AB - EM-X is a mixed consortium of beneficial microorganisms of natural occurrence (lactic bacteria, yeast and photosynthetic bacteria). The aim of this study is to evaluate the antimicrobial activity in-vitro of EM-X to the principal pathogens isolated in clinical settings and to understand if it could be a suitable adjuvant to synthetic antibiotics. According the World Health Organization we performed antimicrobial assays to the main pathogens usually found in hospital wards. After antimicrobial testing, EM-X has been shown to be most effective at a concentration of 40 mg/ml four time concentrated than the commercial original solution (10 mg/ml). The EM-X antimicrobial action, although effective against bacteria, has proved to be ineffective against the candida genus. This active range of concentration (mg/ml) may prove a very weak action of EM, but further investigations will be done to separate the active substances form the inactive ones in this complex mixture. PMID- 30284917 TI - Predictors and patterns of portal use in patients with multiple chronic conditions. AB - Objective To explore predictors of portal use by patients (registered portal users) with multiple chronic conditions according to demographic characteristics and use of specific features hypothesized to support self-management. Methods Two data sources were used in this analysis: electronic health records and 12 months of data from web server log files. Patients ( n = 500) included in the analysis were 45 years or older, registered portal users, and diagnosed with at least two chronic conditions. We fit a negative binomial regression model to predict portal use (number of logins) based on practice size and location, demographic characteristics, and use of specific portal features (secure messaging and patient-entered data). Results Among patients with one or more logins, age, distance separating the patient from his or her primary care provider, and having a diagnosis of heart failure were significant predictors of portal use ( p < .05). No significant differences in portal use were found according to gender, ethnicity, or practice size and location. Conclusion Considering the extraordinary investment on implementation and meaningful use of portal technology, low overall use and the large number of registered non-users is especially troubling. Regardless, our results demonstrate potential opportunities to leverage portal technology especially for patients living in rural and underserved areas to improve self-management of chronic illness.

PMID- 30284919 TI - Managing difficult and violent adolescents ( adolescents difficiles) in France: a genealogical approach. AB - 'Difficult adolescent' is a clinical category defined by psychiatrists' expertise. Since the end of the 1990s, it has been extensively used to describe a population of disruptive, violent yet vulnerable adolescents, at the margins of public institutions that manage youth deviancy in France. For the present study, an interconnected network of 49 documents was analysed using a genealogical method in order to provide comprehensive elements in the results. This category found its ecological niche in the 1960s, revealing a moral tension in the use of constraint. It addressed new problems of intractable individuals, whose dangerousness and vulnerability require coordination between penal, social and psychiatric institutions. It defines an ambiguous condition, suspended between the trouble experienced by the caregivers and an adolescent's individual disorder. PMID- 30284920 TI - The longitudinal associations among grandparent-grandchild cohesion, cultural beliefs about adversity, and depression in Chinese rural left-behind children. AB - This study examined the effects of grandparent-grandchild cohesion on the cross lagged associations between depression and cultural beliefs about adversity in a sample of 625 rural left-behind children in China. Grandparent-grandchild cohesion was concurrently and longitudinally associated with children's depression and cultural beliefs about adversity. Cultural beliefs about adversity mediated the associations between grandparent-grandchild cohesion and children's depression, while depression mediated the associations between grandparent grandchild cohesion and children's beliefs about adversity. Left-behind status differences were also found in mediation models. These findings suggest the important role of grandparent-grandchild cohesion in left-behind children's adjustment. PMID- 30284921 TI - Identification of Enterococci, Staphylococci, and Enterobacteriaceae from Slurries and Air in and around Two Pork Farms. AB - In this study, we investigated the airborne dissemination of bacteria from the inside of two very different pork farms (an intensively confined farm and an open range farm) to the immediate environment. Samples were taken from the slurry, from the air inside the farms (area 0), and from their immediate surroundings at a distance of 50, 100, and 150 m in four directions (north, south, east, and west). A control sample in the air of a zone far away from human or animal activity was also taken. Identification of isolates was made by means of the matrix-assisted laser desorption-ionization time of flight system. A total of 1,063 isolates were obtained, of which a mere 7 came from the air of the control area. Staphylococci, enterococci, and Enterobacteriaceae were selectively targeted for isolation and represented 48.6, 27.2, and 21.6% of the isolates, respectively. The species identified from the air of surrounding areas ( Enterococcus faecalis, Enterococcus hirae, and Staphylococcus arlettae, mainly) were also present inside the farms studied. The results suggest that air is involved in bacterial dissemination, and pork farms should be considered a potential source of foodborne bacteria that might contaminate surrounding areas, including vegetable orchards. Wind direction appears as a factor involved in bacterial dispersion through the air, but its effect may be conditioned by existing vegetation and orographic conditions. PMID- 30284922 TI - Presence and Distribution of Histo-Blood Group Antigens in Pacific Oysters and the Effects of Exposure to Noroviruses GI.3 and GII.4 on Their Expression. AB - Noroviruses (NoVs) are one of the most important foodborne viral pathogens worldwide. Oysters are common carriers of NoVs and are responsible for their transmission. NoVs recognize human histo-blood group antigens (HBGAs) as receptors. Recent studies indicate that HBGA-like molecules also exist in oyster tissues and that they may play a key role in the binding of NoVs. However, the mechanism by which different genotypes of NoV accumulate in different oyster tissues is unknown. In this study, the presence and distribution of different types of HBGA-like molecules were evaluated in 240 oysters collected from the Shandong Peninsula of People's Republic of China for 1 year. The HBGA-like molecules were detected at various rates and expressed at different levels in different tissues. Immunohistochemistry confirmed the diversity of HBGA-like molecules in four oyster tissues. Eight types of HBGA-like molecules (types A, B, H1, Lewis x, Lewis y, Lewis a, Lewis b, and precursor) were assessed in different tissues. Of these, the type A HBGA-like molecule was consistently expressed in the gills, digestive tissue, and mantle, while types H1 and Lewis b HBGA-like molecules were expressed in the digestive tissues. The expression of HBGA-like molecules in response to the NoV challenge was investigated. The levels of types A, H1, and Lewis x increased significantly in specific oyster tissues after exposure to genogroup II, genotype 4 (GII.4) or genogroup I, genotype 3 (GI.3) NoV. The real-time reverse transcription PCR assays indicated that GI.3 NoV mainly accumulated in the digestive tissues of oysters, whereas GII.4 NoV accumulated in the gills, mantle, and digestive tissues. These results provide new insights into the mechanism of NoV bioaccumulation in oysters and suggest that NoV accumulation in oysters may be related to the expression of HBGA-like molecules. PMID- 30284923 TI - Infrared multiple photon dissociation of cesium iodide clusters doped with mono-, di- and triglycine. AB - Charged cesium iodide clusters doped with mono-, di- and triglycine serve as a model system for sea salt aerosols containing biological molecules. Here, we investigate reactions of these complexes under infrared irradiation, with spectra obtained by infrared multiple photon dissociation. The cluster ions are generated via electrospray ionization and analyzed in the cell of a Fourier Transform Ion Cyclotron Resonance Mass Spectrometer. Depending on the cluster size and peptide length, loss of HI or loss of a glycine unit is observed. The experimental measurements are supported by quantum chemical calculations. We show that N-H and O-H stretching modes dominate the spectrum, with large shifts depending on local interactions, namely due to interaction with iodide anions or intramolecular hydrogen bonding. Both experiment and theory indicate that several isomers are present in the experimental mixture, with different infrared fingerprints as well as dissociation pathways. PMID- 30284924 TI - INTRATRACHEAL ADMINISTRATION OF MESENCHYMAL STEM-CELL-DERIVED EXTRACELLULAR VESICLES REDUCES LUNG INJURY IN A RAT MODEL OF BRONCHOPULMONARY DYSPLASIA. AB - Mesenchymal stem cells (MSCs) prevent the onset of bronchopulmonary dysplasia (BPD) in animal models, an effect that seems to be mediated by their secreted extracellular vesicles (EVs). The aim of this study was to compare the protective effects of intratracheally (IT)-administered MSCs vs. MSC-EVs in a hyperoxia induced rat model of BPD. At birth, rats were distributed as follows: animals raised in ambient air for 2 weeks (n=10); and animals exposed to 60% oxygen for 2 weeks and treated with IT-administered physiological solution (n=10), MSCs (n=10), or MSC-EVs (n=10) on postnatal days 3, 7, and 10. The sham-treated hyperoxia-exposed animals showed reductions in total surface area of alveolar air spaces, and total number of alveoli (Nalv), and an increased mean alveolar volume (Valv). EVs prompted a significant increase in Nalv (P<0.01), and a significant decrease in Valv (P<0.05) compared with sham-treated animals, while MSCs only significantly improved Nalv (P<0.05). Small pulmonary vessels of the sham-treated hyperoxia-exposed rats also showed an increase in medial thickness, which only EVs succeeded in preventing significantly (P<0.05). In conclusion, both EVs and MSCs reduce hyperoxia-induced damage, with EVs obtaining better results in terms of alveolarization and lung vascularization parameters. This suggests that IT administered EVs could be an effective approach to BPD treatment. PMID- 30284926 TI - IL-10 Producing B Cells Regulate Th1/Th17 Cell Immune Responses in Pneumocystis Pneumonia. AB - Pneumocystis pneumonia (PCP) is a common opportunistic infectious disease that is prevalent in immunosuppressed hosts. Accumulating evidence shows that B cells play an important role in infectious diseases. In the present study, the immune regulatory role of mature B cells in host defense to Pneumocystis was evaluated. Pneumocystis infection resulted in a decrease in B cells in patients and mice, and the Pneumocystis burden in B cell-deficient (MUMT) mice also progressively increased from weeks 1 to 7 after infection. The clearance of Pneumocystis was delayed in BAFF-R-deficient mice (BAFF-R-/- mice), which had few B cells and Pneumocystis-specific IgG and IgM antibodies, compared with clearance in wild type (WT) mice. There were fewer effector CD4+ T cells and higher percentages of Th1/Th17 cells in BAFF-R-/- mice than in WT mice. Adoptive transfer of naive B cells, mRNA sequencing, and IL-1beta neutralization experiments indicated that IL 1beta is a likely determinant of the B10 cell-mediated suppression of Th1/Th17 cell immune responses in BAFF-R-/- PCP mice. Our data indicated that B cells play a vital role in the regulation of T helper cells in response to Pneumocystis infection. PMID- 30284925 TI - TAILS proteomics reveals dynamic changes in airway proteolysis controlling protease activity and innate immunity during COPD exacerbations. AB - Dysregulated protease activity is thought to cause parenchymal and airway damage in COPD. Multiple proteases have been implicated in COPD and identifying their substrates may reveal new disease mechanisms and treatments. However as proteases interact with many substrates which may be protease inhibitors or proteases themselves, these webs of protease interactions make the wider consequences of therapeutically targeting proteases difficult to predict. We therefore used a systems approach to determine protease substrates and protease activity in COPD airways. Protease substrates were determined by proteomics using Terminal Amine Isotopic Labelling of Substrates (TAILS) methodology in paired sputum samples during stable COPD and exacerbations. Protease activity and specific protein degradation in airway samples were assessed using western blotting, substrate assays and ex vivo cleavage assays. 299 proteins were identified in human COPD sputum, 125 of which were proteolytically processed including proteases, protease inhibitors, mucins, defensins, complement and other innate immune proteins. During exacerbations, airway neutrophils and neutrophil proteases increased. More proteins were cleaved, particularly at multiple sites, consistent with degradation and inactivation. During exacerbations, different substrates were processed including protease inhibitors, mucins and complement proteins. Exacerbations were associated with increasing airway elastase activity and increased processing of specific elastase substrates including secretory leukocyte protease inhibitor. Proteolysis regulates multiple processes including elastase activity and innate immune proteins in COPD airways and differs during stable disease and exacerbations. The complexity of protease, inhibitor and substrate networks makes the effect of protease inhibitors hard to predict which should be used cautiously.

AB - Non-visual opsin receptors have recently been implicated in blue light mediated photorelaxation of smooth muscle in various organs. Since photorelaxation has not yet been demonstrated in airway smooth muscle (ASM) or in human tissues, we questioned whether functional opsin receptors are expressed in mouse and human ASM. Messenger RNA encoding the opsin 3 receptor was detected in both human and mouse airway smooth muscle. To demonstrate the functionality of the opsin receptors, we performed wire myography of ex vivo airway smooth muscle from mouse and human upper airways. Blue light mediated relaxation of acetylcholine pre constricted airways was intensity and wavelength dependent (maximum relaxation at 430 nm blue light) and was inhibited by blockade of the large conductance calcium activated potassium (BK) channels with iberiotoxin. We further implicated opsin receptors as key mediators in functional photorelaxation by demonstrating increased relaxation in the presence of a G protein receptor kinase 2 (GRK2) inhibitor or an opsin chromophore (9-cis-retinal). We corroborated these responses in peripheral airways of murine precision cut lung slices. This is the first demonstration of photorelaxation in airway smooth muscle via an opsin receptor mediated pathway.

AB - OBJECTIVE: To involve people living with amyotrophic lateral sclerosis (plwALS) in the scoping and identification of research priorities related to the changes in ALS communication including the use of augmentative and alternative communication (AAC). METHODS: Two focus groups of plwALS at early and late stages of change to speech intelligibility were carried out as a patient and participant involvement exercise. The transcriptions of these groups were analyzed thematically and compared between groups. RESULTS: Aspects of anticipation, preparation, adaptation and partnership were identified as key to dealing with communication change as a result of ALS. In particular the involvement of partners was clearly significant, as was the impact on them as well as the plwALS. PlwALS successfully contributed to focus groups and the process of group discussion about communication itself appeared constructive. CONCLUSIONS: Research and new interventions should focus further on how to support the partners of plwALS. Future research with plwALS should place AAC strategies and technology in the context of wider communication and investigate how best to support the anticipation, preparation and adaptation to communication change. Specific areas of research need relating to this support are suggested. IMPLICATIONS FOR REHABILITATION People living with ALS (plwALS) are rarely involved in setting the research agenda in the areas of speech and augmentative and alternative communication (AAC). Enabling plwALS to contribute to research, even those with no speech, is feasible with appropriate support. Feedback indicates that communication change and AAC are experienced in different ways by plwALS. Research and intervention should focus on how to support the anticipation, preparation and adaptation to communication change for plwALS. PMID- 30284930 TI - Joining up the dots. PMID- 30284929 TI - Varinostat Alters Gene Expression Profiles in Aortic Tissues from ApoE-/- Mice. AB - Atherosclerosis (AS) is a complex, chronic inflammatory disease that is characterized by plaque buildup within arterial vessel walls. Preclinical trials have suggested that vorinostat, a pan-histone deacetylase inhibitor (HDACi), reduces vascular inflammation and AS, but the underlying protective mechanism has not been fully elucidated. The present study aimed to identify altered gene expression profiles in aortic tissues from ApoE-/- mice after vorinostat treatment. Male ApoE-/- mice fed a high-fat diet were treated with either vorinostat or vehicle, and the aortic plaque area was quantified 8 weeks after treatment. Aortic tissues were collected from both the vorinostat group (n = 3) and vehicle group (n = 3) for deep sequencing of the cDNA to construct sRNA libraries. Oral administration of vorinostat significantly reduced plaque size in the ApoE-/- mice (p < 0.05). In total, 1,550 differentially expressed mRNAs, 56 differentially expressed miRNAs, and 381 differentially expressed lncRNAs were identified in the vorinostat group compared to the vehicle group. Subsequently, a global lncRNA-miRNA-mRNA triple network was constructed based on the competitive endogenous RNA (ceRNA) theory. The hepatitis C signaling pathway was significantly enriched among the differentially expressed mRNAs from the ceRNA network, which suggests that vorinostat has anti-inflammatory properties. Importantly, the identified target pair of mmu-miR-3075-5p/lncRNA A330023F24Rik/Ldlr may regulate drug response. Upregulation of low-density lipid receptor (Ldlr) and lncRNA-A330023F24Rik and downregulation of mmu-miR-3075-5p were further verified by quantitative real-time polymerase chain reaction. To conclude, vorinostat reduced AS in ApoE-/- mice. Differentially expressed mRNA, lncRNAs, and miRNAs, as well as their interactions and pathways, were identified, which partially explain vorinostat's anti-atherosclerotic effects.

High-throughput sequencing technology has enabled research centers across the globe to begin mapping neural connections and deciphering neural wiring circuits. From huge initiatives in the USA to smaller, but no less important research groups in Europe, the quest to map the brain is becoming a worldwide research goal. PMID- 30284932 TI - The use of commercially available adhesive tapes to preserve cartilage and bone tissue integrity during cryosectioning. AB - The use of fluorescent tags to monitor protein expression and to lineage-trace cells has become a standard complement to standard histological techniques in the fields of embryology, pathology and regenerative medicine. Unfortunately, traditional paraffin embedding protocols can substantially diminish or abolish the native emission signal of the fluorophore of interest. To preserve the fluorescent signal, an alternative is to use cryosectioning; however, this can often result in undesirable artefacts such as tearing or shattering - particularly for mineralized tissues such as bone and cartilage. Here we present a method of using a commercially available tape to stabilize murine femur tissue, thus allowing for cryosectioning of cartilage and bone tissues carrying fluorescent tags without the need for demineralization. PMID- 30284933 TI - Introducing graphical and video abstracts. PMID- 30284934 TI - T-blocker: a simple and robust probe-free quantitative PCR assay to detect somatic mutations down to 0.1% frequency. AB - We have developed a simple and robust probe-free quantitative PCR (qPCR) assay method that can detect minor mutant alleles with a frequency as low as 0.1% in a heterogeneous sample by introducing a novel T-blocker concept to the allele specific PCR method. Four new KRAS and BRAF mutation detection assays were developed and their performance was demonstrated by testing a large number of replicates, utilizing a customized PCR protocol. Highly efficient and specific mutant amplification in conjunction with selective wild-type suppression by the T blocker concept enabled 0.1% detection sensitivity using the intercalating dye based qPCR chemistry instead of more complex target-specific dye-labeled probes. Excellent consistency in sensitivity and specificity of the T-blocker assay concept was demonstrated. PMID- 30284935 TI - Directional high-throughput sequencing of RNAs without gene-specific primers. AB - Ribosomal RNA analysis is a useful tool for characterization of microbial communities. However, the lack of broad-range primers has hampered the simultaneous analysis of eukaryotic and prokaryotic members by amplicon sequencing. We present a complete workflow for directional, primer-independent sequencing of size-selected small subunit ribosomal RNA fragments. The library preparation protocol includes gel extraction of the target RNA, ligation of an RNA oligo to the 5'-end of the target, and cDNA synthesis with a tailed random hexamer primer and further barcoding. The sequencing results of a phytoplankton mock community showed a highly similar profile to the biomass indicators. This method has universal potential for microbiome studies, and is compatible for the 5'-end sequencing of other RNA types with minimum library preparation costs.

AB - Fluorescence (or Forster) resonance energy transfer (FRET) is a straightforward and sensitive technique to evaluate molecular interactions. However, most of the popular FRET pairs suffer cross-excitation of the acceptor, which could lead to false positives. To overcome this problem, we selected a large Stokes shift (LSS) fluorophore as a FRET donor. As a successful example, we employed a new FRET pair mAmetrine (an LSS yellow fluorescence protein)/DY-547 (a cyanine derivative) to substitute CFP/fluorescein that we previously employed to study molecular interactions between cyclic nucleotide-binding domains and cyclic nucleotides. The new FRET pair is practically free of cross-excitation of the acceptor. Namely, a change in the fluorescence spectral shape implies evidence of FRET without other control experiments. PMID- 30284938 TI - Isolation of spheroid-forming single cells from gastric cancer cell lines: enrichment of cancer stem-like cells. AB - Isolation of spheroid-forming cells is important to investigate cancer stem cell (CSC) characteristics. However, conventional tumor spheroid culture methods have not proven suitable because the aggregated spheroids generally maintain their original heterogeneity and harbor multiple cells with various characteristics. Here we cultured spheroids using a polydimethylsiloxane microwell-based method and a limiting dilution protocol. We then isolated and enriched for CSCs that formed single cell-derived spheroids from gastric cancer cell lines. Cells from the microwell demonstrated higher self-renewal, increased expression of stem cell markers and resistance to apoptosis compared with spheroid cells made by the traditional method. This novel approach allows efficient cancer stem cell isolation and represents a step forward in cancer stem cell studies. PMID- 30284939 TI - Mammalian cell culture density determination using a laser through-beam sensor. AB - High-throughput protein expression platforms are increasingly used to produce proteins for many applications: to support studies in structure/function, regulation and proteomics, as well as for direct use as potential biotherapeutic agents for medical applications. Here we describe a device that we refer to as the flask density reader (FDR) consisting of a through-beam laser and sensor, and a customized culture flask-receiving nest. The FDR has been integrated onto GNF SystemTM's automated protein expression platform to enable rapid, noninvasive, fully automated spectrophotometric determination of cell densities in suspension mammalian cell cultures. The FDR reduces the risk of culture contamination from frequent flask sampling and greatly reduces the time and effort needed to count cells using off-line methods. PMID- 30284940 TI - Prepregnancy Factors Are Associated with Development of Hypertension Later in Life in Women with Pre-Eclampsia. AB - BACKGROUND: The aim of our study was to investigate the prepregnancy characteristics that are risk factors for the development of hypertension (HTN) and identify prepregnancy factors for the development of HTN in women affected by pre-eclampsia in their first pregnancy. METHODS: We enrolled 1910 women who had undergone a National Health Screening Examination through the National Health Insurance Corporation between 2002 and 2003, and who had their first delivery affected by pre-eclampsia in 2004. Women were classified as having HTN if they were newly diagnosed with HTN from 2005 through 2012. RESULTS: After 8 years of follow-up, 7.7% (148/1910) of pre-eclamptic women developed HTN. Using the Cox proportional hazards model, old age (hazard ratio [HR] 3.92, 95% confidence interval [CI] 2.47-6.23), a family history of HTN (HR 2.28, 95% CI 1.46-3.58), prepregnancy obesity (HR 3.74, 95% CI 2.50-5.59), and high blood pressure (BP) (HR 2.78, 95% CI 1.85-4.19) were independently associated with the development of HTN. CONCLUSIONS: The results show that the development of HTN in pre-eclamptic women is related to prepregnancy factors. Recognizing who subsequently develops HTN postpartum in pre-eclamptic women with these prepregnancy factors could lead to early identification and lifestyle interventions, which could reduce the burden of cardiovascular disease. PMID- 30284941 TI - In vitro investigation into the forces involved during lipofilling. AB - Breast augmentation using implants is the most common aesthetic and reconstructive breast surgical procedure. Complications such as implant rupture maybe related to surgical technique and damage to the implant. Autologous fat transfer (lipofilling) using metallic cannulae has become a standard adjunctive, yet there is little evidence on lipofilling safety in the presence of implants. The aims of this study are to verify the effects of different cannulae and to quantify the forces applied by surgeons during lipofilling. Silicone gel-filled textured implants (200 mL), mounted on a specially constructed mould were ruptured with two different cannulae: type A (hole at tip: sharp) and type B (hole away from tip: blunt), driven at three speeds (10, 100 and 1000 mm/min), and the force at rupture was recorded. In addition, the maximum 10 forces over a 30-s period applied by 11 plastic surgeons against a breast implant in an in vitro environment were recorded using a load cell attached to a type-A cannula. Statistical analysis of comparative results was performed using t-tests, with p < 0.05 considered significant. Results showed that the implant ruptured at forces up to 25% lower when cannula A was used compared to cannula B. This supports current technique in lipofilling in the use of a blunt tipped cannula. There was a significant difference between some displacement rates only, due to the viscoelastic nature of the material. The tactile force that surgeons use during lipofilling was modelled in vitro and showed a range of maximum forces between 0.23 and 16.8 N, with a mean maximum value of 6.9 N. Limitation of this study is that it may not reflect in vivo behaviour of breast implants. More studies are needed to confirm the safety of breast lipofilling in the presence of implants using these data as a starting point.

AB - Traditional doctors have been largely ignored in HIV prevention, particularly primary prevention. As part of a structural intervention programme to reduce HIV risk among young women in Botswana, we trained 147 traditional doctors in four districts as well as government health education assistants (HEAs) and teachers to run discussion groups in the community and schools, using an evidence-based eight-episode audio-drama, covering gender roles, gender violence, and how these are related to HIV risk. One year later, we contacted 43 of the 87 trained traditional doctors in two districts. Most (32) were running discussion groups with men and women, with links to the local HEAs and teachers. They were adept at recruiting men to their groups, often a challenge with community interventions, and reported positive changes in attitudes and behaviour of group participants. Traditional doctors can play an important role in primary prevention of gender violence and HIV. PMID- 30284944 TI - OUTCOMES OF SNARE-RELATED INJURIES TO ENDANGERED MOUNTAIN GORILLAS ( GORILLA BERINGEI BERINGEI) IN RWANDA. AB - Mountain gorillas ( Gorilla beringei beringei) are one of the most critically endangered great apes in the world. The most common cause of mountain gorilla morbidity and mortality is trauma (e.g., injury from conspecifics or snare entrapment). We conducted a retrospective case-control study of free-ranging, human-habituated mountain gorillas to evaluate factors associated with snare entrapment and the results of clinical intervention. Data were collected from clinical records on all clinical intervention cases ( n=132) in Volcanoes National Park, Rwanda, conducted between 1995-2015. Gorilla doctors treated 37 gorillas entrapped in snares and 95 gorillas for other clinical conditions (including trauma and respiratory illness). Multivariate statistical analyses revealed that young gorillas (<8 yr old) were more likely than older gorillas to become snared; that comorbidities delayed times to intervention (>=3 d); and that severity of wounds at the time of intervention were associated with increased risk of lasting impairment (including loss of limb or limb function, or death) within 1 mo after intervention. Our results may influence decisions for gorilla health monitoring and treatment to most effectively conserve this critically endangered species. PMID- 30284945 TI - Dichotomous Locomotor Recoveries Are Predicted by Acute Changes in Segmental Blood Flow after Thoracic Spinal Contusion Injuries in Pigs. AB - Neuroimaging facilitates the translation of animal pre-clinical research to human application. The large porcine spinal cord is useful for testing invasive interventions. Ideally, the safety and efficacy of a delayed intervention is tested in pigs that have recovered sufficiently after spinal cord injury (SCI) to allow either deterioration or improvement of function to be detected. We set out to create moderate severity T9 injuries in Yucatan minipigs by conducting a bridging study adapting methods previously developed in infant piglets. The injury severity was varied according to two pneumatic impactor parameters: the piston compression depth into tissue or the velocity. To stratify locomotor recovery, a 10-point scale used in prior piglet studies was redefined through longitudinal observations of spontaneous recovery. Using hindlimb body weight support to discriminate injury severity, we found that end-point recovery was strongly bimodal to either non-weight-bearing plegia with reciprocating leg movements (<5/10) or recovery of weight bearing that improved toward a ceiling effect (>= 8/10). No intermediate recovery animals were observed at 2 months post injury. The ability of intra-operative ultrasound and acute magnetic resonance imaging (MRI) to provide immediate predictive feedback regarding tissue and vascular changes following SCI was assessed. There was an inverse association between locomotor outcome and early gray matter hemorrhage on MRI and ultrasound. Epicenter blood flow following contusion predicted recovery or non-recovery of weight-bearing. The depth of the dorsal cerebrospinal fluid space, which varied between animals, influenced injury severity and confounded the results in this fixed-stroke paradigm. PMID- 30284947 TI - Biological and Genomic Characterization of a Novel Tobamovirus Infecting Hoya spp. AB - Foliar symptoms suggestive of virus infection were observed on the ornamental plant hoya (Hoya spp.; commonly known as waxflower) in Florida. An agent that reacted with commercially available tobamovirus detection reagents was mechanically transmitted to Chenopodium quinoa and Nicotiana benthamiana. Rod shaped particles ~300 nm in length and typical of tobamoviruses were observed in partially purified virion preparations by electron microscopy. An experimental host range was determined by mechanical inoculation with virions, and systemic infections were observed in plants in the Asclepiadaceae, Apocynaceae, and Solanaceae families. Some species in the Solanaceae and Chenopodiaceae families allowed virus replication only in inoculated leaves, and were thus only local hosts for the virus. Tested plants in the Amaranthaceae, Apiaceae, Brassicaceae, Cucurbitaceae, Fabaceae, and Malvaceae did not support either local or systemic virus infection. The complete genome for the virus was sequenced and shown to have a typical tobamovirus organization. Comparisons of genome nucleotide sequence and individual gene deduced amino acid sequences indicate that it is a novel tobamovirus sharing the highest level of sequence identity with Streptocarpus flower break virus and members of the Brassicaceae-infecting subgroup of tobamoviruses. The virus, for which the name Hoya chlorotic spot virus (HoCSV) is proposed, was detected in multiple hoya plants from different locations in Florida. PMID- 30284946 TI - Autistic Traits in the Neurotypical Population do not Predict Increased Response Conservativeness in Perceptual Decision Making. AB - Recent research has shown that adults and children with autism spectrum disorders have a more conservative decision criterion in perceptual decision making compared to neurotypical individuals, meaning that autistic participants prioritise accuracy over speed of a decision. Here, we test whether autistic traits in the neurotypical population correlate with increased response conservativeness. We employed three different tasks; for two tasks we recruited participants from China ( N = 39) and for one task from the United Kingdom ( N = 37). Our results show that autistic traits in the neurotypical population do not predict variation in response criterion. We also failed to replicate previous work showing a relationship between autistic traits and sensitivity to coherent motion and static orientation. Following the argument proposed by Gregory and Plaisted-Grant, we discuss why perceptual differences between autistic and neurotypical participants do not necessarily predict perceptual differences between neurotypical participants with high and low autistic traits. PMID- 30284948 TI - Mycoplasmosis of House Finches ( Haemorhous mexicanus) and California Scrub-Jays ( Aphelocoma californica) in a Wildlife Rehabilitation Facility with Probable Nosocomial Transmission. AB - We describe an investigation of an outbreak of conjunctivitis in juvenile House Finches ( Haemorhous mexicanus) and California Scrub-jays ( Aphelocoma californica) at a central California wildlife rehabilitation facility. In late May 2015, the facility began admitting juvenile finches, the majority with normal eyes at intake. In June, with juvenile finches already present, the facility admitted additional juvenile scrub-jays, again all with normal eyes at intake. In July, after conjunctivitis was observed in increasing numbers of juvenile finches and scrub-jays, carcasses were submitted for postmortem examination. Histopathology of five finches and three scrub-jays identified lymphocytic infiltrates in the ocular tissues. Conjunctival swabs from 87% (13/15) finches and 33% (4/12) scrub-jays were PCR-positive for Mycoplasma gallisepticum. One finch and two scrub-jays were PCR-positive for Mycoplasma synoviae. Additionally, gene sequencing (16S rRNA and 16S-23S intergenic spacer region) identified Mycoplasma sturni from 33% (3/9) scrub-jays. This outbreak of conjunctivitis suggested that M. gallisepticum-infected juvenile finches admitted to and maintained in a multispecies nursery likely resulted in transmission within the facility to healthy juvenile finches and scrub-jays. Evidence of other Mycoplasma spp. in finches and scrub-jays indicates that these species are susceptible to infection and may act as carriers. This outbreak highlighted the need for effective triage and biosecurity measures within wildlife rehabilitation facilities. PMID- 30284949 TI - In vivo conversion of astrocytes to oligodendrocyte lineage cells using chemicals: targeting gliosis for myelin repair. AB - AIM: It would be clinically ideal to target astrocytes in vivo for conversion into oligodendrocyte lineage cells to reduce astrogliosis and generate new myelinating cells. MATERIALS & METHODS: Here, we prepared a GFP-labeled human astrocyte cell line, treated with epigenetic modifiers trichostatin A or 5 azacytidine and transplanted them into cuprizone-induced demyelinated mice brains. The fate of the transplanted astrocytes was studied at days 7, 14 and 28 post-transplantation. RESULTS: GFP+ astrocytes were reduced over time, whereas the GFP+ oligodendrocyte lineage cells were found on days 14 and 28. Nontreated astrocytes did not convert to myelinating cells following transplantation. Cell conversion was proved in vitro by maintaining the treated cells in oligodendrocyte progenitor cell medium. CONCLUSION: These findings seem promising for the application of epigenetic modifiers, especially their targeted delivery to glial scars to treat demyelinating diseases. PMID- 30284950 TI - Advance care planning in community dwellers: A constructivist grounded theory study of values, preferences and conflicts. AB - BACKGROUND: Most laypeople have not engaged in any advance care planning. Yet they are expected to articulate choices for life-sustaining interventions when they need admission to an acute care hospital in Canada. AIM: To describe how laypeople understand and make decisions for life-sustaining interventions when engaging in advance care planning. DESIGN: Semi-structured interviews using constructivist grounded theory methodology and purposive sampling. SETTING: Mid size Canadian urban community Participants: In total, 20 healthy laypeople, 55 years and older, participated in in-depth semi-structured face-to-face interviews. Theoretical sampling was used to explore findings from the first round of interviews. Ten participants were invited for repeat interviews. RESULTS: Four major themes were identified. Most participants claimed at the outset that they had engaged in advance care planning, but they were unfamiliar with contemporary life-sustaining interventions and had not factored these into their decisions. Participants' confidence in their substitute decision makers precluded them from having explicit discussions with these individuals. Participants expressed their values and preferences in terms of unacceptable functional outcomes from serious illness, rather than desired interventions. The process of articulating their preferences within the interviews was subject to decision conflicts, which in turn helped them re-evaluate and refine their decisions. CONCLUSION: Advance care planning for the healthy older adult is challenging. Meaningful engagement may lead to conflicts in decision-making. Efforts to improve engagement must reflect what patients know and understand, their focus on unacceptable negative outcomes rather than interventions, and the need for iterative discussions with health-care providers. PMID- 30284951 TI - GENETIC RELATEDNESS OF EPIZOOTIC HEMORRHAGIC DISEASE VIRUS SEROTYPE 2 FROM 2012 OUTBREAK IN THE USA. AB - During summer and early fall of 2012, the US experienced the largest outbreak of hemorrhagic disease (HD) on record; deer (both Odocoileus virginianus and Odocoileus hemionus) in 35 states were affected, including many northern states where HD typically does not occur. Epizootic hemorrhagic disease virus (EHDV) was the predominant virus isolated, with serotype 2 (EHDV-2) representing 66% (135/205) of all isolated viruses. Viruses within the EHDV serogroup are genetically similar, but we hypothesized that subtle genetic distinctions between viruses would exist across the geographic range of the outbreak if multiple EHDV 2 strains were responsible. We examined viral relatedness and molecular epidemiology of the outbreak by sequencing the mammalian binding protein (VP2) gene and the insect vector binding protein (VP7) gene of 34 EHDV-2 isolates from 2012 across 21 states. Nucleotide sequences of VP2 had 99.0% pairwise identity; VP7 nucleotide sequences had 99.1% pairwise identity. Very few changes were observed in either protein at the amino acid level. Despite the high genetic similarity between isolates, subtle nucleotide differences existed. Both VP2 and VP7 gene sequences separated into two distinct clades based on patterns of single nucleotide polymorphisms after phylogenetic analysis. The clades were divided geographically into eastern and western clades, although those divisions were not identical between VP2 and VP7. There was also an association between percent sequence identity and geographic distance between isolates. We concluded that multiple EHDV-2 strains contributed to this outbreak. PMID- 30284952 TI - Can the use of proprioceptive knee braces have implications in the management of osteoarthritic knees: An exploratory study. AB - BACKGROUND: Use of proprioceptive knee braces to control symptomology by altering neuromuscular control mechanisms has been shown in patellofemoral pain. Although their potential in patients with knee osteoarthritis is vast, little research has examined their efficacy. OBJECTIVES: This study examines the effect of a proprioceptive knee brace on lower limb kinematics and kinetics in healthy participants and in participants with OA. METHODS: Thirteen healthy participants were asked to perform a 10-cm step-down task with and without a proprioceptive brace. Data were collected using a 10-camera Qualisys system. Individuals with osteoarthritis completed the Knee injury and Osteoarthritis Outcome Score before and after 4 weeks of intervention. RESULTS: During step-down reductions in knee maximum internal rotation, transverse range of movement, transverse plane angular velocity and maximum internal rotation angular velocity was seen. Ankle plantar flexion and inversion angular velocity decreased while inversion and maximum supination angular velocity increased. Improvements in Knee injury and Osteoarthritis Outcome Score were noted across all parameters with brace use. CONCLUSION: Positive changes in kinematic variables in multiple planes can be achieved with proprioceptive bracing alongside improved patient outcome. These changes occur at the knee but analysis of other weight bearing joints should not be overlooked in future studies. This study supports the concept of neuromuscular reinforcement and re-education through proprioceptive bracing and its application in the management in knee osteoarthritis. Clinical relevance Proprioception can alter symptoms and biomechanics embraced and adjacent lower limb joints. The results of this study highlights the potential uses of non-mechanical bracing in the treatment of osteoarthritis and other potential to bridge the osteoarthritis treatment gap. Furthermore, large-scale research is needed to match disease subset to brace type. PMID- 30284953 TI - Candidatus Liberibacter asiaticus and its vector, Diaphorina citri, augments the TCA cycle of their host via the GABA shunt and polyamines pathway. AB - Huanglongbing, a destructive citrus disease, is associated with Candidatus Liberibacter asiaticus (CLas), which is transmitted by the Asian citrus psyllid, Diaphorina citri. Both CLas and its vector manipulate the host metabolism for their benefit to meet their nutritional needs and neutralize the host defense responses. We used a targeted GC-MS-based method to explore the connection between TCA cycle, gamma-aminobutyric acid (GABA)-shunt and polyamines (PAs) pathways in citrus. CLas and D. citri accelerated the conversion of alpha ketoglutarate to glutamate, then to GABA, causing an accumulation of GABA in the cytosol. In silico analysis showed that citrus genome possesses a putative GABA permease that connects the GABA-shunt with TCA cycle and supports the accumulation of succinate, fumarate, and citrate. Additionally, the PAs biosynthetic pathway might be connected directly to the TCA cycle through the production of fumarate, or indirectly via enhancement of GABA-shunt. Taken together, we suggest that GABA-shunt and PAs pathway are alternative pathways that contribute to the flux towards succinate rather than an intact TCA cycle in citrus. Both CLas and its vector enhance these pathways. This study provides more insights into citrus responses to the HLB pathosystem, and could be a further step to providing clues for understanding the nutritional needs of CLas, which could help in culturing CLas. PMID- 30284954 TI - Platelet-rich plasma lyophilization enables growth factor preservation and functionality when compared with fresh platelet-rich plasma. AB - AIMS: To compare levels and activity of the growth factors between fresh and lyophilized platelet-rich plasma (PRP). METHODS: Analysis of platelet concentration using fibroblast and human umbilical vein endothelial cell cultures were compared between fresh and lyophilized PRP obtained from peripheral blood. RESULTS: After lyophilization, 54% of platelets were intact whereas the fresh showed no aggregation with agonists (levels under 20%). The concentration of growth factors (VEGF, EGF, TGF-beta and PDGF) in both products were similar. Fresh and lyophilized PRPs induced proliferation in the fibroblasts at 24 h (0.303 vs 0.300, respectively). CONCLUSION: Lyophilized PRP appears to be an alternative to fresh PRP and the results evidenced the role of growth factors as a key element in the activity of this product.

AB - Organ transplant recipients are at a higher risk of pre-malignant human papillomavirus-associated lesions due to immunosuppression.

PMID- 30284956 TI - The first mite: insect genealogy in Hooke's Micrographia. AB - What happens when you take the idea of the biblical Adam-the first human - and apply it to insects? You create an origin story for Nature's tiniest creatures, one that gives them 'a Pedigree as ancient as the first creation'. This the naturalist Robert Hooke argued in his treatise, the Micrographia (1665). In what follows, I will retrace how Hooke endeavoured to show that insects-then widely believed to have arisen out of the dirt - were the products of an ancient lineage. These genealogies, while constructed from empirical observation, were conjectures of the imagination. Section 2 shows how Hooke introduced the concept of a 'prime parent' (an Adam-insect) to explain the anatomical similarities between 'mites'. Section 3 demonstrates how Hooke defined the family of "gnats" as tiny machines built from the same components and relates Hookean genealogies to contemporary ideas about Noah's Ark. Section 4 shows how Hooke outlined the morphology of 'insects' (delineating what we now call arthropods). Section 5 explores how Hooke used fossils to study these animals in the distant past. In sum, Hooke was turning natural history - collecting and describing insects - into natural history: reconstructing their origins. PMID- 30284957 TI - Proteomics investigation of the changes in serum proteins after high- and low flux hemodialysis. AB - PURPOSE: This study aimed to use proteomics methods to investigate the changes in serum protein levels after high- and low-flux hemodialysis (HD). METHODS: Before and after HD, serum samples were obtained from two selected patients who were treated with a Polyflux 140 H high-flux dialyzer and a Polyflux 14 L low-flux dialyzer during two continuous therapy sessions. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was performed to identify the proteins. RESULTS: A total of 212 and 203 serum proteins were identified after high-flux and low-flux HD, respectively. After high-flux HD, 21 proteins increased, and 132 proteins decreased. After low-flux HD, 87 proteins increased, and 45 proteins decreased. High-flux HD led to a significantly greater reduction in protein levels than low flux HD (0.73 +/- 0.13 vs. 0.84 +/- 0.18, p = .00). Among the increased and decreased proteins, the isoelectric point (pI) values mainly ranged from 5 to 7, and the molecular weights (Mws) were mostly smaller than 30 kDa. The serum proteins showed no difference in pI or Mw for high- and low-flux HD. Gene ontology (GO) analysis showed that the detected proteins were related to immune system processes and complement activation. CONCLUSIONS: Serum protein levels differentially changed after high- and low-flux HD. Long-term effects should be observed in future studies.

AB - Myelomeningocele (MMC) is a devastating congenital neural tube defect, which results in the exposure of spinal cord to the intrauterine environment leading to secondary spinal cord injury and severe impairment. Though, the mechanisms underlying the secondary pathogenesis are clinically relevant, the exact cause of in utero acquired spinal cord damage remains unclear. The objective of this study was to determine whether the Hyaluronic acid (HA) concentration in amniotic fluid (AF) in the retinoic acid-induced model of MMC is different from that in normal controls and whether these differences could have an impact on the viscosity of AF. Our data shows that the concentration of HA in AF samples from fetuses with MMC (MMC-AF) and normal control samples (Norm-AF) were not significantly different at embryonic day 18 (E18) and E20. Thereafter, the HA concentration significantly increased in Norm-AF but not in MMC-AF. Compared with Norm-AF, the concentration of HA in MMC-AF and the viscosity of MMC-AF were significantly lower at E21. Agarose gel electrophoresis confirmed a significant reduction in the HA level of MMC-AF compared to Norm-AF at E21. No HA degrading activity was detected in MMC-AF. In summary, we identified a deficiency in the AF level of HA and the viscosity of AF in fetal rats with MMC. This data is discussed in relation to a potential role the reduction in the AF viscosity due to the low level of HA may play in the exacerbating effects of mechanical trauma on spinal cord damage at the MMC lesion site.

AB - IMPACT STATEMENT: This study compared side-by-side the impact of donor age on the production of tissue-engineered small intestine (TESI). Each age represents a specific period of life: E18 for fetuses, 5-day-old pups for neonates, 21-day-old rats for weanlings, and 6-week-old rats for adults. The TESI produced was compared macroscopically and microscopically. The mechanism(s) contributing to the differences observed was explored by detecting proliferating cells in the TESI and by analyzing intestinal stem cell gene expression in donor cells. These data may provide valuable information for future application of TESI clinically.

AB - Following the discovery of diamonds in Botswana, there was widespread use of plastic bags, possibly as a positive reaction to the change in economic and financial landscape of the country. The excessive use of plastic bags by consumers throughout Botswana, however, imposed several negative externalities to the environment and consequently to livelihoods through their effects on wildlife and livestock. The government of Botswana, in an effort to mitigate the negative impacts of plastic bags on the environment, introduced both a ban of plastics with less than minimum thickness and a plastic bag levy. This study assesses if the plastic bag levy regulation by the government is achieving its goal of reducing the use of plastic bags in Botswana, where Maun is used as a case study. It analyses consumers' perceptions about the plastic levy and its effects on their consumption. A total of 154 semi-structured questionnaires were administered through random selections of respondents at two shopping malls in Maun. In conclusion, the study established that although the levy is well targeted on consumers as sources of plastic bag litter, the levy is yet to attain its intended purpose of effecting a reduction of plastic bags demanded and/or consumed in Maun.

AB - Stroke is among the top 10 causes of death in children and survivors carry resulting disabilities for decades, at substantial cost to themselves and their families. Children are not currently able to access reperfusion therapies, due to limited evidence supporting safety and efficacy and long diagnostic delays. The Australian Clinical Consensus Guideline for the Diagnosis and Acute Management of Childhood Stroke was developed to minimize unwarranted variations in care and document best evidence on the risk factors, etiologies, and conditions mimicking stroke that differ from adults. Clinical questions were formulated to inform systematic database searches from 2007 to 2017, limited to English and pediatric studies. SIGN methodology and the National Health and Medical Research Council system were used to screen and classify the evidence. The Grades of Recommendation, Assessment, Development, and Evaluation system (GRADE) was used to grade evidence as strong or weak. The Guideline provides more than 60 evidence based recommendations to assist prehospital and acute care clinicians in the rapid identification of childhood stroke, choice of initial investigation, to confirm diagnosis, determine etiology, selection of the most appropriate interventions to salvage brain at risk, and prevent recurrence. Recommendations include advice regarding the management of intracranial pressure and congenital heart disease. Implementation of the Guideline will require reorganization of prehospital and emergency care systems, including the development of regional stroke networks, pediatric Code Stroke, rapid magnetic resonance imaging and accreditation of primary pediatric stroke centers with the capacity to offer reperfusion therapies. The Guideline will allow auditing to benchmark timelines of care, access to acute interventions, and outcomes. It will also facilitate the development of an Australian childhood stroke registry, with data linkage to international registries, to allow for accurate data collection on stroke incidence, treatment, and outcomes.

AB - Sorption and degradation are considered two primary modes of pollutant removal by microorganisms, and extracellular polymeric substances (EPS) have been shown to play an important role in these biological processes. However, their role in removing refractory organic pollutants the effects of intracellular substances in microorganisms remain unclear. In this study, we investigated both the removal mechanism and intracellular substances involved in removing the pollutant acenaphthene (ACE) from Pseudomonas sp. bacteria in anaerobic conditions. The results indicated that the ACE was mainly adsorbed rather than degraded by bacteria. Moreover, ACE had little impact on EPS secretion at concentrations ranging 0-3 mg/L. Cell walls and membranes accounted for more than 70% of ACE adsorption, whereas intra-cellular substances accounted for about 10-25% and the effect of other components on ACE adsorption was not obvious. A possible mechanism of ACE removal by bacteria is proposed. PMID- 30284963 TI - RECENT CHANGES IN INFECTIOUS DISEASES IN EUROPEAN WILDLIFE. AB - Many infectious diseases originating from, or carried by, wildlife affect wildlife conservation and biodiversity, livestock health, or human health. We provide an update on changes in the epidemiology of 25 selected infectious, wildlife-related diseases in Europe (from 2010-16) that had an impact, or may have a future impact, on the health of wildlife, livestock, and humans. These pathogens were selected based on their: 1) identification in recent Europe-wide projects as important surveillance targets, 2) inclusion in European Union legislation as pathogens requiring obligatory surveillance, 3) presence in recent literature on wildlife-related diseases in Europe since 2010, 4) inclusion in key pathogen lists released by the Office International des Epizooties, 5) identification in conference presentations and informal discussions on a group email list by a European network of wildlife disease scientists from the European Wildlife Disease Association, or 6) identification as pathogens with changes in their epidemiology during 2010-16. The wildlife pathogens or diseases included in this review are: avian influenza virus, seal influenza virus, lagoviruses, rabies virus, bat lyssaviruses, filoviruses, canine distemper virus, morbilliviruses in aquatic mammals, bluetongue virus, West Nile virus, hantaviruses, Schmallenberg virus, Crimean-Congo hemorrhagic fever (CCHF) virus, African swine fever virus, amphibian ranavirus, hepatitis E virus, bovine tuberculosis ( Mycobacterium bovis), tularemia ( Francisella tularensis), brucellosis ( Brucella spp.), salmonellosis ( Salmonella spp.), Coxiella burnetii, chytridiomycosis, Echinococcus multilocularis, Leishmania infantum, and chronic wasting disease. Further work is needed to identify all of the key drivers of disease change and emergence, as they appear to be influencing the incidence and spread of these pathogens in Europe. We present a summary of these recent changes during 2010-16 to discuss possible commonalities and drivers of disease change and to identify directions for future work on wildlife-related diseases in Europe. Many of the pathogens are entering Europe from other continents while others are expanding their ranges inside and beyond Europe. Surveillance for these wildlife-related diseases at a continental scale is therefore important for planet-wide assessment, awareness of, and preparedness for the risks they may pose to wildlife, domestic animal, and human health.

AB - The use of traditional medicine for the treatment of various disorders is not a new practice. Indeed, various categories of traditional healers form a large part of the healthcare workforce in many low- and middle-income countries, and given the paucity of mental health professionals in these countries, traditional and complementary medicine practitioners are utilised even more so for mental disorders. In Ghana, efforts have been made to formalise and standardise the work of traditional medicine practitioners. This goal is still mostly unmet, partly due to the lack of scientific knowledge of their beliefs, methods, and practices in mental healthcare. Very few studies have documented this knowledge. In this article, we report on some of the methods that are used by traditional Ghanaian herbalists in treating mental disorders. Eight herbalists working within the Greater Accra Region, who specialised in mental health, were interviewed through individual semi-structured interviews. Thematic analysis showed that traditional herbalists' work in treating mental disorders revolved around four key themes: the method of diagnosis; the treatment methods used; the mode of administering the treatment; and the purpose of the specific treatment. These themes are discussed with reference to their potential implications for patients' care and outcomes. PMID- 30284966 TI - Amnion-Based Scaffold with Enhanced Strength and Biocompatibility for In Vivo Vascular Repair. AB - Current vascular replacement grafts used in congenital heart defect corrective surgery have poor longevity and growth potential. Recipient patients often require multiple reoperations. Tissue engineering has the promise to produce a graft with the potential to grow, remodel, and repair. In this study, we aimed at developing an amnion-based scaffold suitable for cardiovascular tissue engineering applications and in vivo usage. The developed human amnion-based scaffold was made by an enzymatic decellularization process followed by freeze drying as a single or multilayered structure. These structures were compared to native amnion for seeded cell viability and biomechanical properties then tested for in vivo biocompatibility. Our results demonstrated that while native amnion tissue supported little cell growth, the decellularized-amnion allowed cell engraftment and survival. In addition, preservation of the scaffold by freeze drying as a single layer allowed cell engraftment and growth. Multilayering the freeze-dried amnion scaffolds resulted in a similar cell growth potential of the single layered construct but superior mechanical strength. The multilayered construct showed in vitro biocompatibility with endothelial cells, smooth muscle cells, cardiac myocytes, and thymus and cord blood-derived mesenchymal stem cells (MSCs). When implanted in a piglet model of left pulmonary artery grafting, the multilayered construct showed its in vivo suitability and biocompatibility for vascular repair as demonstrated by the development of newly formed endothelium in the intima, a smooth muscle cell-rich medial layer and an adventitia containing new vasa vasorum. In conclusion, our developed amnion-derived scaffold represents an off-the-shelf biocompatible structure that can be seeded with the patient's own MSCs to produce an autologous vascular graft. PMID- 30284967 TI - Animal models for stem cell-based pulp regeneration: Foundation for human clinical applications. AB - Rapid progress has been made in the last decade related to stem cell-mediated pulp-dentin regeneration, from characterization of dental pulp stem cells (DPSCs) to the first-ever reported clinical case in humans. However, many challenges still need to be addressed before such technology can become a common clinical practice; therefore, further rigorous research is needed. Animal study models are very important to test new ideas, concepts, and technologies. This review summarizes and discusses several key animal models that have been utilized to investigate pulp-dentin regeneration. From a tissue regeneration perspective, we categorize the animal model by the location where the regenerated pulp tissue is formed: ectopic, semi-orthotopic, and orthotopic. Several animal species are discussed, including mouse, ferret, dog, and mini-swine. Mouse is used for ectopic pulp-dentin regeneration in the dorsum subcutaneous space. A commonly tested approach is hydroxyapatite/tricalcium phosphate granules (HA-TCP) model used to observe ectopic pulp-dentin complex formation. The semi-orthotopic model includes tooth slices or fragments with which de novo pulp regeneration in a root canal space can be tested in the mouse subcutaneous space. For orthotopic pulp regeneration, the canine teeth of ferrets are large enough for such purposes. As non-primate large animal models, dog and mini-swine teeth have many aspects quite similar to those of humans, allowing researchers to perform experiments that mimic clinical conditions in humans. The protocols established and the data obtained from large animal studies may directly relate to and apply to future human studies. Complete orthotopic pulp regeneration has been demonstrated in dogs and mini-swine. The use of allogeneic and subpopulations of DPSCs for pulp regeneration, and testing of the periapical disease model and aging model have been performed in mini-swine or dogs. In sum, all these animal models will help to address challenges that still face pulp regeneration in humans. We need to thoroughly utilize these models to test new ideas, technologies, and strategies before reliable and predictable clinical protocols can be established for human clinical trials or treatment. PMID- 30284968 TI - Adjunctive colposcopy technologies for assessing suspected cervical abnormalities: systematic reviews and economic evaluation. AB - BACKGROUND: Dynamic Spectral Imaging System (DySIS)map (DySIS Medical Ltd, Edinburgh, UK) and ZedScan (Zilico Limited, Manchester, UK) can be used adjunctively with conventional colposcopy, which may improve the detection of cervical intraepithelial neoplasia (CIN) and cancer. OBJECTIVES: To systematically review the evidence on the diagnostic accuracy, clinical effectiveness and implementation of DySISmap and ZedScan as adjuncts to standard colposcopy, and to develop a cost-effectiveness model. METHODS: Four parallel systematic reviews were performed on diagnostic accuracy, clinical effectiveness issues, implementation and economic analyses. In January 2017 we searched databases (including MEDLINE and EMBASE) for studies in which DySISmap or ZedScan was used adjunctively with standard colposcopy to detect CIN or cancer in women referred to colposcopy. Risk of bias was assessed with the Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 tool. Summary estimates of diagnostic accuracy were calculated using bivariate and other regression models when appropriate. Other outcomes were synthesised narratively. A patient-level state transition model was developed to evaluate the cost-effectiveness of DySISmap and ZedScan under either human papillomavirus (HPV) triage or the HPV primary screening algorithm. The model included two types of clinics ['see and treat' and 'watchful waiting' (i.e. treat later after confirmatory biopsy)], as well as the reason for referral (low-grade or high-grade cytological smear). Sensitivity and scenario analyses were undertaken. RESULTS: Eleven studies were included in the diagnostic review (nine of DySISmap and two of ZedScan), three were included in the clinical effectiveness review (two of DySISmap and one of ZedScan) and five were included in the implementation review (four of DySISmap and one of ZedScan). Adjunctive DySISmap use was found to have a higher sensitivity for detecting CIN grade 2+ (CIN 2+) lesions [81.25%, 95% confidence interval (CI) 72.2% to 87.9%] than standard colposcopy alone (57.91%, 95% CI 47.2% to 67.9%), but with a lower specificity (70.40%, 95% CI 59.4% to 79.5%) than colposcopy (87.41%, 95% CI 81.7% to 91.5%). (Confidential information has been removed.) The base-case cost effectiveness results showed that adjunctive DySISmap routinely dominated standard colposcopy (it was less costly and more effective). The only exception was for high-grade referrals in a watchful-waiting clinic setting. The incremental cost-effectiveness ratio for ZedScan varied between L272 and L4922 per quality-adjusted life-year. ZedScan also dominated colposcopy alone for high grade referrals in see-and-treat clinics. These findings appeared to be robust to a wide range of sensitivity and scenario analyses. LIMITATIONS: All but one study was rated as being at a high risk of bias. There was no evidence directly comparing ZedScan with standard colposcopy. No studies directly compared DySIS and ZedScan. CONCLUSIONS: The use of adjunctive DySIS increases the sensitivity for detecting CIN 2+, so it increases the number of high-grade CIN cases that are detected. However, it also reduces specificity, so that more women with no or low grade CIN will be incorrectly judged as possibly having high-grade CIN. The evidence for ZedScan was limited, but it appears to increase sensitivity and decrease specificity compared with colposcopy alone. The cost-effectiveness of both adjunctive technologies compared with standard colposcopy, under both the HPV triage and primary screening algorithms, appears to be favourable when compared with the conventional thresholds used to determine value in the NHS. FUTURE WORK: More diagnostic accuracy studies of ZedScan are needed, as are studies assessing the diagnostic accuracy for women referred to colposcopy as part of the HPV primary screening programme.

AB - Core-shell nanowires made of Si and Ge can be grown experimentally with excellent control for different sizes of both core and shell. We have studied the structural properties of Si/Ge and Ge/Si core-shell nanowires aligned along the [Formula: see text] direction, with diameters up to 10.2 nm and varying core to shell ratios, using linear scaling density functional theory. We show that Vegard's law, which is often used to predict the axial lattice constant, can lead to an error of up to 1%, underlining the need for a detailed ab initio atomistic treatment of the nanowire structure. We analyse the character of the intrinsic strain distribution and show that, regardless of the composition or bond direction, the Si core or shell always expands. In contrast, the strain patterns in the Ge shell or core are highly sensitive to the location, composition and bond direction. The highest strains are found at heterojunction interfaces and the surfaces of the nanowires. This detailed understanding of the atomistic structure and strain paves the way for studies of the electronic properties of core-shell nanowires and investigations of doping and structure defects.

AB - An unpredicted fourfold screw N-H...O hydrogen bond C(4) motif in a primary dicarboxamide (trans-cyclohexane-1,4-dicarboxamide, C8H14N2O2) was investigated by single-crystal X-ray diffraction and IR and Raman spectroscopies. Electron density topology and intermolecular energy analyses determined from ab initio calculations were employed to examine the influence of weak C-H...O hydrogen-bond interactions on the peculiar arrangement of molecules in the tetragonal P43212 space group. In addition, the way in which the co-operative effects of those weak bonds might modify their relative influence on molecular packing was estimated from cluster calculations. Based on the results, a structural model is proposed which helps to rationalize the unusual fourfold screw molecular arrangement. PMID- 30284969 TI - Cellular localization of the cell cycle inhibitor Cdkn1c controls growth arrest of adult skeletal muscle stem cells. AB - Adult skeletal muscle maintenance and regeneration depend on efficient muscle stem cell (MuSC) functions. The mechanisms coordinating cell cycle with activation, renewal, and differentiation of MuSCs remain poorly understood. Here, we investigated how adult MuSCs are regulated by CDKN1c (p57kip2), a cyclin dependent kinase inhibitor, using mouse molecular genetics. In the absence of CDKN1c, skeletal muscle repair is severely impaired after injury. We show that CDKN1c is not expressed in quiescent MuSCs, while being induced in activated and proliferating myoblasts and maintained in differentiating myogenic cells. In agreement, isolated Cdkn1c-deficient primary myoblasts display differentiation defects and increased proliferation. We further show that the subcellular localization of CDKN1c is dynamic; while CDKN1c is initially localized to the cytoplasm of activated/proliferating myoblasts, progressive nuclear translocation leads to growth arrest during differentiation. We propose that CDKN1c activity is restricted to differentiating myoblasts by regulated cyto-nuclear relocalization, coordinating the balance between proliferation and growth arrest.

AB - The determination of the crystal structure of the M phase, (MnxZn1-x)2V2O7 (0.75 < x < 0.913), in the pseudobinary Mn2V2O7-Zn2V2O7 system for x ? 0.8 shows that the previously published triclinic unit-cell parameters for this thortveitite related phase do not describe a true lattice for this phase. Instead, single crystal X-ray data and Rietveld refinement of synchrotron X-ray powder data show that the M phase has a different triclinic structure in the space group P-1 with Z = 2. As prior work has suggested, the crystal structure can be described as a distorted version of the thortveitite crystal structure of beta-Mn2V2O7. A twofold superstructure in diffraction patterns of crystals of the M phase used for single-crystal X-ray diffraction work arises from twinning by reticular pseudomerohedry. This superstructure can be described as a commensurate modulation of a pseudo-monoclinic basis structure closely related to the crystal structure of beta-Mn2V2O7. In comparison with the distortions introduced when beta-Mn2V2O7 transforms at low temperature to alpha-Mn2V2O7, the distortions which give rise to the M phase from the beta-Mn2V2O7 prototype are noticeably less pronounced.

The title compound was synthesized using solution methods and its structure was characterized by single-crystal X-ray diffraction. The investigated compound contains a new [HAs2Mo6O26(H2O)]5- polyanion and crystallizes in the monoclinic space group P21/c.

AB - Structures are reported for eight Schiff bases derived from various salicylaldehydes: five are newly synthesized and re-investigations are reported for three previously reported structures, leading, in each case, to some revision of previous conclusions. In (E)-N-(3,4-dimethylisoxazol-5-yl)-4-[(2 hydroxybenzylidene)amino]benzenesulfonamide, C18H17N3O4S, (I), and (E)-4-[(5 bromo-2-hydroxy-3-methoxybenzylidene)amino]-N-(3,4-dimethylisoxazol-5 yl)benzenesulfonamide. C19H18BrN3O5S, (II), the isoxazole rings adopt different orientations relative to the rest of the molecules, despite the additional substituents in (II) being in the aryl ring remote from the isoxazole unit. The molecules of both (E)-4-bromo-2-[(2-hydroxyphenylimino)methyl]-6-methoxyphenol, C14H12BrNO3, (III), and (E)-4-bromo-2-methoxy-6-[(2 methoxyphenylimino)methyl]phenol, C15H14BrNO3, (IV), are both effectively planar; while (III) adopts the phenol-imine constitution, (IV) adopts the keto-amine constitution. (E)-2-Methoxy-6-[(2-methoxyphenylimino)methyl]phenol, C15H15NO3, (V), which was determined previously using powder X-ray data assuming the phenol imine constitution, has now been refined from single-crystal X-ray data, confirming the phenol-imine constitution. In (E)-3-benzoyl-2-[(5-fluoro-2 hydroxybenzylidene)amino]-4,5,6,7-tetrahydrobenzo[b]thiophene, C22H18FNO2S, (VI), the fused carbocyclic ring exhibits conformational disorder; both disorder components, having populations of 0.705 (4) and 0.295 (4), adopt half-chair conformations. The isostructural (E)-3-benzoyl-2-[(2-hydroxybenzylidene)amino)] 4,5,6,7-tetrahydrobenzo[b]thiophene, C22H19NO2S, (VII), which was originally reported as having a fully ordered structure [Kaur et al. (2014). Acta Cryst. E70, o476-o477], has been rerefined using the original data set and found to exhibit the same type of disorder as found in (VI), with disordered populations having occupancies of 0.851 (3) and 0.149 (3). The triclinic polymorph of (E)-[(2 hydroxyphenylimino)methyl]phenol, C13H11NO2, (VIII), which crystallizes with Z' = 2 in the space group P-1, has been described variously as occurring as the keto amine tautomer [Maciejewska et al. (1999). J. Phys. Org. Chem. 12, 875-880] and as the phenol-imine tautomer [Tunc et al. (2009). J. Chem. Crystallogr. 39, 672 676]. Rerefinement of this structure using one of the original data sets shows that both of the independent molecules exist in the keto-amine form. In the structures of compounds (I), (VI), (VII) and (VIII), hydrogen bonds generate simple chains, while a chain of rings is formed in (V). Sheets are formed by hydrogen bonds in both (II) and (III), while in (IV), the sheet structure is built from aromatic pi-pi stacking interactions.

Structural peculiarities of homoleptic tris(iminophenoxide)s (1)-(3), binuclear tris(iminophenoxide) (4) and homoleptic ate tetrakis(iminophenoxide) (5) are discussed. The nonflat Schiff base ligand displays MU2 kappa3O1,N,O2:kappaO1 bridging, and kappa3O1,N,O2 and kappa2N,O1 terminal coordination modes, depending on steric congestion, which in turn depends on the ionic radii of the rare-earth metals and the number of coordinated ligands. It has been demonstrated that interligand dihedral angles of the phenoxide ligand are convenient for comparing steric hindrance in complexes. (4).MeOH has a flat Y2O2 rhomboid core and exhibits both inter- and intramolecular MeO-H...Cl hydrogen bonding. Catalytic systems based on complexes (1)-(3) and (5) have demonstrated medium catalytic performance in acrylonitrile polymerization, providing polyacrylonitrile samples with narrow polydispersity.

AB - A novel two-dimensional CoII coordination framework, namely poly[(MU2-biphenyl 4,4'-diyldicarboxylato-kappa2O4:O4'){MU2-bis[4-(2-methyl-1H-imidazol-1-yl)phenyl] ether-kappa2N3:N3'}cobalt(II)], [Co(C14H8O4)(C20H18N4O)]n, has been prepared and characterized by IR, elemental analysis, thermal analysis and single-crystal X ray diffraction. The crystal structure reveals that the compound has an achiral two-dimensional layered structure based on opposite-handed helical chains. In addition, it exhibits significant photocatalytic degradation activity for the degradation of methylene blue. PMID- 30284978 TI - A new one-dimensional CdII coordination polymer incorporating 2,2'-(1,2 phenylene)bis(1H-imidazole-4,5-dicarboxylate). AB - Imidazole-4,5-dicarboxylic acid (H3IDC) and its derivatives are widely used in the preparation of new coordination polymers owing to their versatile bridging coordination modes and potential hydrogen-bonding donors and acceptors. A new one dimensional coordination polymer, namely catena-poly[[diaquacadmium(II)]-MU3-2,2' (1,2-phenylene)bis(1H-imidazole-4,5-dicarboxylato)], [Cd(C16H6N4O8)0.5(H2O)2]n or [Cd(H2Phbidc)1/2(H2O)2]n, has been synthesized by the reaction of Cd(OAc)2.2H2O (OAc is acetate) with 2,2'-(1,2-phenylene)bis(1H-imidazole-4,5-dicarboxylic acid) (H6Phbidc) under solvothermal conditions. In the polymer, one type of Cd ion (Cd1) is six-coordinated by two N atoms and two O atoms from one H2Phbidc4- ligand and by two O atoms from two water molecules, forming a significantly distorted octahedral CdN2O4 coordination geometry. In contrast, the other type of Cd ion (Cd2) is six-coordinated by two N atoms and two O atoms from two symmetry related H2Phbidc4- ligands and by two O atoms from two symmetry-related water molecules, leading to a more regular octahedral coordination geometry. The Cd1 and Cd2 ions are linked by H2Phbidc4- ligands into a one-dimensional chain which runs parallel to the b axis. In the crystal, the one-dimensional chains are connected through hydrogen bonds, generating a two-dimensional layered structure parallel to the ab plane. Adjacent layers are further linked by hydrogen bonds, forming a three-dimensional structure in the solid state.

AB - The title compound, poly[(MU2-formato-kappa3O,O':O)[MU2-4-(pyridin-4-yl)benzoato kappa3N:O,O']zinc(II)], [Zn(C12H8NO2)(HCOO)]n, has been synthesized in situ and characterized by thermogravimetric analysis (TGA) and single-crystal and powder X ray diffraction analyses. The polymer contains two independent structural units in the asymmetric unit. These are constructed from Zn2+ ions, 4-(pyridin-4 yl)benzoate (4-pbc) bridges and in-situ-generated formate ligands, forming two similar two-dimensional (2D) layer structures. These similar 2D layers are arranged alternately and are linked with each other by dense C-H...O hydrogen bonds to generate a three-dimensional (3D) supramolecular framework. The crystal is pseudomerohedrally twinned about [201]. Compared with free 4-Hpbc, the polymer exhibits a red shift and significantly enhanced solid-state luminescence properties.

AB - This article presents the synthesis of three new 4-thiopyrimidine derivatives obtained from ethyl 4-methyl-2-phenyl-6-sulfanylpyrimidine-5-carboxylate as the starting material, namely, ethyl 4-[(4-chlorobenzyl)sulfanyl]-6-methyl-2 phenylpyrimidine-5-carboxylate, C21H19ClN2O2S, (2), {4-[(4-chlorobenzyl)sulfanyl] 6-methyl-2-phenylpyrimidin-5-yl}methanol, C19H17ClN2OS, (3), and 4-[(4 chlorobenzyl)sulfanyl]-5,6-dimethyl-2-phenylpyrimidine, C19H17ClN2S, (4), which vary in the substituent at the 5-position of the pyrimidine ring. The compounds were characterized by 1H NMR, 13C NMR, IR and mass spectroscopies, and also elemental analysis. The molecular structures were further studied by single crystal X-ray diffraction. Compound (2) crystallizes in the space group P-1 with one molecule in the asymmetric unit, whereas compounds (3) and (4) crystallize in the space group P21/c with two and one molecule, respectively, in their asymmetric units. The conformation of each molecule is best defined by the dihedral angles formed between the pyrimidine ring and the planes of the two aryl substituents attached at the 2- and 4-positions. The only structural difference between the three compounds is the substituent at the 5-position of the pyrimidine ring, but they present significantly different features in the hydrogen-bond interactions. Compound (2) displays a one-dimensional chain formed by hydrogen bonds and the chains are further extended into a two-dimensional network. Molecules of (3) and (4) generate one-dimensional chains formed through intermolecular interactions. The study examines the cytotoxicity of compounds (3) and (4) against Human umbilical vein endothelial cells (HUVEC) and HeLa, K562 and CFPAC cancer cell lines. The presence of the hydroxymethyl and methyl groups in (3) and (4), respectively, offers an interesting new insight into the structures and behaviour of these derivatives. Compound (4) was found to be nontoxic against CFPAC and HUVEC; however, it shows weak activity against the HeLa and K563 cell lines. The presence of a hydroxy group in (3) significantly increases its cytotoxicity towards both, i.e. the cancer (HeLa, K562 and CFPAC) and normal (HUVEC) cell lines.

AB - Germanophosphates, as a young class of metal phosphates, have been less reported but might possess more diverse structural types and potential applications. Here, two one-dimensional (1D) alkali-metal germanophosphates (GePOs), namely, hydrogen hexakis(MU-hydrogen phosphato)digermaniumtrirubidium, HRb3Ge2(HPO4)6 (1), and caesium bis(MU-hydrogen phosphato)(MU-hydroxido)germanium, CsGe(HPO4)2(OH) (2), have been prepared by the solvothermal method. Compound 1 shows 1D [Ge(HPO4)6]infinity chains along the c axis formed by GeO6 octahedra and PO4 tetrahedra, with Rb+ cations dissociated between the chains. Compound 2 also exhibits 1D [Ge(HPO4)4(OH)2]infinity chains constructed from adjacent Ge(HPO4)4(OH)2 octahedra, with Cs+ cations dissociated between the chains. XRD, TGA, IR and UV-Vis-NIR absorption spectra are presented and discussed for both compounds. PMID- 30284982 TI - Crystal structure and sequential dehydration transitions of disodium guanosine 5' monophosphate tetrahydrate. AB - Disodium guanosine 5'-monophosphate was reported previously to crystallize as both the tetrahydrate and the heptahydrate. We herein report a determination of the molecular and crystal structures of the title tetrahydrated salt, 2Na+.C10H12N5O8P2-.4H2O. It was found that the structure differs markedly from that of the heptahydrate, but greatly resembles that of disodium deoxyguanosine 5'-monophosphate tetrahydrate. The C2'-O2'H moiety of ribose is surrounded by hydrophilic moieties and is disordered over two sites. The sugar puckering mode is O4'-endo-C1'-exo at both sites and the conformation around the C4'-C5' bond is gauche-trans. Powder X-ray diffraction and thermal analyses revealed that the temperature-controlled transition from the tetrahydrate to the anhydride proceeded through three intermediate phases between 40 and 60 degrees C at 0% relative humidity. Large induction periods were observed. PMID- 30284983 TI - Dilithium (citrate) crystals and their relatives. AB - New compounds of the type LiMHC6H5O7 (M = Li, Na, K, Rb) have been prepared from the metal carbonates and citric acid in solution. The crystal structures have been solved and refined using laboratory powder X-ray diffraction data, and optimized using density functional techniques. The compounds crystallize in the triclinic space group P-1 and are nearly isostructural. The structures are lamellar, with the layers in the ab plane. The boundaries of the layers consist of hydrophobic methylene groups and very strong intermolecular O-H...O hydrogen bonds. The O...O distances range from 2.666 A for M = Li to 2.465 A for M = Rb. The Li-O bonds exhibit significant covalent character, while the heavier M-O bonds are ionic. The Li atoms are four-, five-, or six-coordinate, while the coordination numbers of the larger cations are higher, i.e. eight for Na and nine for K and Rb. The citrate anion occurs in the trans,trans conformation, one of the two low-energy conformations of an isolated citrate anion. The crystal structure of LiRbHC6H5O7.H2O was also solved and refined. It consists of the same layers as in the anhydrous M = Rb compound, with interlayer water molecules and a different hydrogen-bonding pattern. PMID- 30284985 TI - Notch signaling suppresses glucose metabolism in mesenchymal progenitors to restrict osteoblast differentiation. AB - Notch signaling critically controls cell fate decisions in mammals, both during embryogenesis and in adults. In the skeleton, Notch suppresses osteoblast differentiation and sustains bone marrow mesenchymal progenitors during postnatal life. Stabilizing mutations of Notch2 cause Hajdu-Cheney syndrome, which is characterized by early-onset osteoporosis in humans, but the mechanism whereby Notch inhibits bone accretion is not fully understood. Here, we report that activation of Notch signaling by either Jagged1 or the Notch2 intracellular domain suppresses glucose metabolism and osteoblast differentiation in primary cultures of bone marrow mesenchymal progenitors. Importantly, deletion of Notch2 in the limb mesenchyme increases both glycolysis and bone formation in the long bones of postnatal mice, whereas pharmacological reduction of glycolysis abrogates excessive bone formation. Mechanistically, Notch reduces the expression of glycolytic and mitochondrial complex I genes, resulting in a decrease in mitochondrial respiration, superoxide production, and AMPK activity. Forced activation of AMPK restores glycolysis in the face of Notch signaling. Thus, suppression of glucose metabolism contributes to the mechanism, whereby Notch restricts osteoblastogenesis from bone marrow mesenchymal progenitors. PMID- 30284984 TI - Synthesis, crystal structures and anti-inflammatory activity of four 3,5 bis(arylidene)-N-benzenesulfonyl-4-piperidone derivatives. AB - 3,5-Bis(arylidene)-4-piperidone (BAP) derivatives display good antitumour and anti-inflammatory activities because of their double alpha,beta-unsaturated ketone structural characteristics. If N-benzenesulfonyl substituents are introduced into BAPs, the configuration of the BAPs would change significantly and their anti-inflammatory activities should improve. Four N-benzenesulfonyl BAPs, namely (3E,5E)-1-(4-methylbenzenesulfonyl)-3,5-bis[4 (trifluoromethyl)benzylidene]piperidin-4-one dichloromethane monosolvate, C28H21F6NO3S.CH2Cl2, (4), (3E,5E)-1-(4-fluorobenzenesulfonyl)-3,5-bis[4 (trifluoromethyl)benzylidene]piperidin-4-one, C27H18F7NO3S, (5), (3E,5E)-1-(4 nitrobenzenesulfonyl)-3,5-bis[4-(trifluoromethyl)benzylidene]piperidin-4-one, C27H18F6N2O5S, (6), and (3E,5E)-1-(4-cyanobenzenesulfonyl)-3,5-bis[4 (trifluoromethyl)benzylidene]piperidin-4-one dichloromethane monosolvate, C28H18F6N2O3S.CH2Cl2, (7), were prepared by Claisen-Schmidt condensation and N sulfonylation. They were characterized by NMR, FT-IR and HRMS (high resolution mass spectrometry). Single-crystal structure analysis reveals that the two 4 (trifluoromethyl)phenyl rings on both sides of the piperidone ring in (4)-(7) adopt an E stereochemistry of the olefinic double bonds. Molecules of both (4) and (6) are connected by hydrogen bonds into one-dimensional chains. In (5) and (7), pairs of adjacent molecules embrace through intermolecular hydrogen bonds to form a bimolecular combination, which are further extended into a two-dimensional sheet. The anti-inflammatory activity data reveal that (4)-(7) significantly inhibit LPS-induced interleukin (IL-6) and tumour necrosis factor (TNF-alpha) secretion. Most importantly, (6) and (7), with strong electron-withdrawing substituents, display more potential inhibitory effects than (4) and (5). PMID- 30284986 TI - Patterns and sociodemographic characteristics of substance abuse in Al Qassim, Saudi Arabia: a retrospective study at a psychiatric rehabilitation center. AB - BACKGROUND: The problem of substance abuse is one of the top 20 risk factors for poor health worldwide. Though widely prevalent in the Middle East, there are few studies in Saudi Arabia. OBJECTIVE: Record the pattern of substances abuse and the sociodemographic characteristics of abusers attending the local rehabilitation center. DESIGN: Descriptive, retrospective medical record review. SETTING: Patients admitted to psychiatric rehabilitation center. METHODS: The sample included all patients admitted to a rehabilitation center during the period of January 2016-December 2016. Data was collected retrospectively from patient records. MAIN OUTCOME MEASURES: Descriptive epidemiological data and statistical comparisons. SAMPLE SIZE: 612 patients. RESULTS: The majority of patients (73%) were 21-40 years of age. Polysubstance abuse (60%) and amphetamine (24%) abuse were most predominant in the 20-40 year olds (45%) and high school dropouts (41%). The average number of drugs being used by polysubstance abusers was 2.5 (and the maximum was 6). There was no relationship of family history of drug abuse and mental illness. CONCLUSION: There was an increased use of polysubstances and amphetamine with a decreased abuse of prescription drugs when compared to previous studies reported in Saudi Arabia. There was a decreasing prevalence for heroin and alcohol. Substance abusers have certain epidemiological, social and drug patterns and we recommend that authorities and planners integrate their efforts to look for the reasons for substance abuse. LIMITATIONS: Females not included and prevalence of tobacco smoking not studied. CONFLICT OF INTEREST: None. PMID- 30284987 TI - Expression of androgen receptor in invasive ductal breast carcinomas: a clinicopathological study from Jordan. AB - BACKGROUND: The clinical relevance of androgen receptors (ARs) expressed in breast cancer cells and the suggested prognostic impact has been an area of active research. The prevalence rate of AR expression in breast cancer has never been reported among Jordanian patients. OBJECTIVE: Determine the expression rate of ARs among invasive ductal breast cancer cases of different stages and molecular subtypes. Also, analyze the relationship between AR expression and clinicopathologic and immunohistochemical criteria, and assess the impact of AR expression on survival. DESIGN: Retrospective medical record review. SETTING: Tertiary care hospital in Amman, Jordan. PATIENTS AND METHODS: Our study comprised only of cases of invasive ductal breast carcinoma of no special type among females from records during a 10-year period between 2006 and 2015. Immunohistochemical staining was considered positive if more than 10% of tumor nuclei showed positive staining. MAIN OUTCOME MEASURES: The expression rate of ARs and the association of the expression rate with the clinicopathologic features of invasive breast cancer. SAMPLE SIZE: 293. RESULTS: Immunohistochemical staining for AR revealed positive stain.ing in 180 (61.4%) cases, including approximately 50% of triple-negative breast cancer cases. AR positivity correlated with estrogen receptor (ER) status (P=.007) and smaller T size (P=.014). However, no significant association was found with any of the other variables. AR expression was positively associated with overall survival (P=.022) in general and in ER-positive cases (P=.012). However, in the multivariate Cox regression model, AR was not independently associated with survival. CONCLUSIONS: These results were consistent with international reports showing a significant relationship of AR expression with ER status. In addition, AR expression was significantly associated with smaller tumor size. Although AR status was not independently associated with survival, our data suggest AR is a good prognostic factor. LIMITATIONS: Some clinical data were missing. CONFLICT OF INTEREST: None. PMID- 30284988 TI - An 18-year study of thyroid carcinoma in the western region of Saudi Arabia: a retrospective single-center study in a community hospital. AB - BACKGROUND: Thyroid carcinoma (TC) is the ninth most common site of all cancers in women in the world and the second most common malignancy in Saudi Arabia. This reports updates data on the epidemiology of the disease in Saudi Arabia. OBJECTIVE: Describe and interpret changes in the frequency of TC to compare with other populations and determine proportions of certain histological types of TC. DESIGN: Medical record review. SETTING: Military hospital in Jeddah, Saudi Arabia. PATIENTS AND METHODS: We reviewed the pathological and clinical records from January 2000 to December 2017 of patients with TC. MAIN OUTCOME MEASURES: Frequency and types of TC. SAMPLE SIZE: 347 patients. RESULTS: Over the 18-year period, out of 456 patients with TC, 347 patients had sufficiently complete records: 275 (79.3%) were female and 72 (20.7%) were male for a female to male ratio of 3.8:1. The mean (SD) age at surgery of all patients was 45.2 (16.0) years. There were 287 (82.7%) cases of papillary TC. The next common malignancy was follicular TC with 32 (9.2%) cases followed by Hurthle cell cancer with 11 (3.2%) cases. Lymphoma was found in only 7 (2%) cases. All TC types occurred at a younger age in females than males except for lymphoma. All TC types occurred with the greatest frequency in the fourth and fifth decades. There was a 2.3-fold increase in the number of TCs from 8 (2.3%) in 2000 to 26 (7.5%) in 2017. The rate per 100000 residents of Jeddah increased for the period from 2000 to 2002 from 1.6 to 3.4 for 2015-2017. Papillary TC cases in females accounted for most of the increase. CONCLUSION: Our findings are consistent with similar studies worldwide. Etiological factors promoting the rise in TC must be investigated and may provide insight in developing suitable management strategies for the Saudi population.

PMID- 30284989 TI - Outcomes and hospital admission patterns in patients with diabetes during Ramadan versus a non-fasting period. AB - BACKGROUND: Fasting during Ramadan is a challenge for Muslim patients with diabetes and for their healthcare providers. However, data on the effects of Ramadan fasting on hospital admissions and outcomes in patients with diabetes are scarce. OBJECTIVES: Evaluate the characteristics of patients with diabetes admitted during the fasting month of Ramadan compared with the non-fasting month of Dhu al-Qidah. DESIGN: A retrospective cohort study medical record review. SETTING: A university teaching hospital. PATIENTS AND METHODS: We reviewed the records of all patients with diabetes admitted to the medical department at Benghazi Medical Center, including medical ward, intensive care unit and coronary care unit, during the months of Ramadan and Dhu al-Qidah, 2016. We compared differences in reasons for admission, length of stay and in-hospital mortality between patients admitted during Ramadan and Dhu al-Qidah and between patients who were fasting at time of admission during Ramadan and those who were not. MAIN OUTCOME MEASURES: Main reason for admission, length of stay and in-hospital mortality rate. SAMPLE SIZE: 402 patients with diabetes. RESULTS: During Ramadan, 186 patients were admitted compared with 216 during Dhul al-Qidah. There was no statistically significant difference in reasons for admission, length of hospital stay, or in-hospital mortality (borderline for mortality, P=.078), between patients with diabetes admitted during Ramadan and Dhu al-Qidah. Of those admitted in Ramadan, 59.1% were fasting on admission. Fasting patients admitted during Ramadan had a significantly higher proportion of the diseases of the circulatory system when compared with non-fasting patients (39.4% vs. 23.6%, P=.028) while in-hospital mortality was higher in non-fasting patients (29.2% vs. 8.7%, P less than .001). There was no significant difference in length of stay between fasting and non-fasting patients. CONCLUSIONS: The frequency of admissions for most medical con.ditions were not changed during Ramadan but the frequency of acute coronary syndrome was higher in those who were fasting on admission. Patients with diabetes who were not fasting on admission had more high risk features that prevented them from fasting and therefore are at increased risk of in-hospital mortality.

PMID- 30284990 TI - Implementation of total laboratory automation at a tertiary care hospital in Saudi Arabia: effect on turnaround time and cost efficiency. AB - BACKGROUND: Total laboratory automation (TLA) is a relatively new way of improving the management of high volume clinical laboratories. TLA may reduce staff, reduce operating costs, decrease testing time and provide enhanced process control. OBJECTIVES: Establish a cost efficient TLA that is less labor intensive, improves productivity and reduces turnaround time (TAT). DESIGN: Implementation of TLA for random glucose and troponin-T as sentinel tests to compare change in TAT. SETTING: Tertiary hospital with high volume of laboratory tests. METHODS: Routine patient samples for random glucose and troponin-T were used to capture TAT. Information on staff grades and schedules before and after implementing the TLA, and cost of contracts to deliver the service were collected. MAIN OUTCOME MEASURES: TAT, cost efficiency, and reduction in labor. RESULTS: The consolidation of contracts resulted in a reduction of 28.8 million SAR in direct costs. Staffing cost was reduced by 1.14 million SAR with less senior staff required; there were reductions in staff at both senior and junior level. The overall TAT for all tests was reduced by 32% in 2016 (after TLA implementation) compared to 2012 (before TLA implementation). The median TAT for random glucose tests was reduced by 21% (to 55.7 minutes in 2016 from 70.1 minutes in 2012). Evidence of test optimization by exploring the impact of stat tests, auto dilutions and reruns on the overall TAT of the TLA is shown by comparing troponin T TATs after reclassifying stat tests (in 2016) to routine (in 2017). At the 75th percentile, there was a 27% reduction in TAT when comparing August 2016 to March 2017 with a 19% reduction in median TAT. CONCLUSION: By moving from stat to routine assays, the TAT was reduced, which is counter-intuitive. The use of stat assays slowed down the performance of the TLA. A careful review of the mix of assays should be conducted to maximize performance and to ensure that the system delivers what is required. LIMITATIONS: Room for improvement by systematically analyzing and reviewing the impact of making minor changes that could have significant impact on TAT. CONFLICT OF INTEREST: None. PMID- 30284991 TI - Clinicopathologic characteristics andoutcomes of hepatocellular carcinoma associated with chronic hepatitis B versus hepatitis C infection. AB - BACKGROUND: Hepatocellular carcinoma (HCC) is a primary liver malignancy and one of the most common cancers worldwide. Few studies in Saudi Arabia have compared the clinicopathologic characteristics of HCC caused by hepatitis B virus (HBV) versus hepatitis C virus (HCV) and their effect on patient survival and prognosis. OBJECTIVES: Identify differences in clinicopathological characteristics and outcomes of hepatocellular carcinoma (HCC) caused by HBV versus HCV. DESIGN: A retrospective medical records review. SETTING: Tertiary medical center in Riyadh. PATIENTS AND METHODS: We included all new cases of HCC with underlying HBV and HCV infection diagnosed between January 2013 and September 2017 that met inclusion criteria. MAIN OUTCOME MEASURES: Clinical, biochemical, pathological and radiological characteristics, and survival differences were compared between HCC that developed in HBV- and HCV-infected patients. SAMPLE SIZE: Of 253 patients evaluated, 172 patients were included in the study. RESULTS: Of the 172 patients, 110 (64%) had HCV-associated HCC and 62 (36%) had HBV-associated HCC. More patients with HBV infection were males (P=.003) and were younger (P=.015) than HCV patients. HCV-infected patients who developed HCC had more advanced cirrhosis (P=.048). The prevalence of comorbidities and pre-existing cir.rhosis was similar in both groups. Seven patients (6.8%) with underlying HCV developed HCC in the absence of cirrhosis. Patients with HBV-associated HCC were less likely to meet Milan criteria at initial diagnosis than those with HCV-associated HCC (33.9% vs. 52.7%, respectively, P=.017). HBV-associated HCC occurred at a more advanced Barcelona Clinic Liver Cancer stage. The overall median survival and treatment outcome for each modality was comparable. CONCLUSIONS: HBV- and HCV-associated HCC have distinct clinical and pathological characteristics, necessitating different screening policies to optimize HCC surveillance and management. However, viral etiology did not affect the treatment outcome and long-term survival. LIMITATIONS: Conducted in a single-center, retrospective and lacks information about the use of antiviral treatment. CONFLICT OF INTEREST: None. PMID- 30284993 TI - Outcome with topical sirolimus for port wine stain malformations after unsatisfactory results with pulse dye laser treatment alone. AB - : We used a topical formulation of sirolimus for treating port wine stain (PWS). Although pulsed dye laser (PDL) is the current treatment of choice for PWS, fast neovascularization after treatment is a major drawback. With PDL therapy there has been insufficient improvement and frustrating side effects. The objective was to study the efficacy and safety of combining topical sirolimus with PDL as dual therapy in managing PWS. We report five PWS cases that were treated with PDL initially, followed by 0.5-1% topical sirolimus. With dual therapy there was significant improvement over a shorter duration. More published studies of topical sirolimus are needed to clarify the role of dual therapy in managing PWS associated with capillary malformations. We encourage further prospective and comparative studies with a larger sample size. SIMILAR CASES PUBLISHED: 1.

AB - BACKGROUND: The safety and efficacy of dapoxetine for the treatment of premature ejaculation (PE) is still controversial. Thus, we decided to conduct a meta analysis using trial sequential analysis (TSA) to determine the sufficiency of conclusions. OBJECTIVE: Evaluate the efficacy and safety of dapoxetine in the treatment of patients with PE and assess the reliability of the findings. DESIGN: Meta-analysis of randomized controlled trials (RCTs). METHODS: Electronic databases including PUBMED, EMBASE, Cochrane Library, CNKI and Wanfang data were reviewed up to July 2017. RCTs evaluating the efficacy of dapoxetine in patients with PE and reporting intravaginal ejaculatory latency time (IELT), patient global impression of change (PGIC) and/or adverse events (AEs) were included. MAIN OUTCOME MEASURES: Mean differences between trials in efficacy for IELT, and risk ratios for PGIC and treatment-emergent AEs. SAMPLE: 8 RCTs. RESULTS: For IELT and PGIC, significant effects were found for all doses of dapoxetine versus placebo, and similar results were obtained in subgroups of the 30-mg dose versus 60-mg dose. There were also statistically different dose-related effects on AEs. Trial sequential analysis showed that the result of our meta-analysis was confirmed and further trials are unnecessary. CONCLUSIONS: The evidence suggests that dapoxetine may be a safe and effective drug for patients with PE. REGISTRATION: Not registered, no published protocol.

AB - AIM: To investigate the influence of exogenous lactoferrin (LF) on tumor growth, energy and lipid metabolism of Walker-256 carcinosarcoma and to assess genotoxic effects of LF. MATERIALS AND METHODS: The study was performed on Walker-256 tumor bearing rats. Total lipids and phospholipids were determined by thin-layer chromatography. Comet assay was used to investigate the genotoxic effects of LF. RESULTS: Daily i.p. administrations of exogenous LF at concentrations of 1 mg/kg and 10 mg/kg starting from the 4th day after tumor transplantation suppressed growth of Walker-256 carcinosarcoma by almost 44%. After treatment with recombinant LF in both doses, the phospholipid composition of Walker-256 carcinosarcoma cells was changed (3-fold increase of phosphatidylethanolamine, 3.4-fold increase of phosphatidylcholine, and 1.8-fold increase of sphingomyelin, while the cardiolipin content decreased by 67%. Exogenous LF was not genotoxic for bone marrow cells (as assessed by the ratio of PCE/NCE, number of micronuclei) and peripheral blood lymphocytes (percentage of DNA in the tail of a comet) in Walker-256 carcinosarcoma-bearing rats. CONCLUSION: Exogenous LF caused the inhibition of Walker-256 carcinosarcoma growth and a decrease in the microviscosity of plasma cell membranes, and exerted no genotoxicity toward bone marrow cells and peripheral blood of experimental animals. PMID- 30284997 TI - Influence of metformin, sodium dichloroacetate and their combination on the hematological and biochemical blood parameters of rats with gliomas C6. AB - BACKGROUND: The efficacy of antimetabolic therapy of malignant neoplasms could not be explained solely by the direct mechanisms of action of such energy metabolism inhibitors as sodium dichloroacetate (DCA) and metformin (MTF). The indirect effects of DCA and MTF on the organs and tissues, which could play significant role in the antitumor activity of these agents, have not been thoroughly explored. AIM: To investigate the effect of MTF, DCA and their combination on the survival of rats with C6 glioma and major haematological and biochemical blood parameters. MATERIALS AND METHODS: DCA and MTF were administered orally to inbred female rats for 11 days starting from the second day after tumor cell transplantation at a total dose of 1.1 and 2.6 g/kg, respectively. When combined treatment was used, MTF was administered 3 hours after the administration of DCA. The content of lactate and pyruvate in blood plasma was determined on the ChemWell(r) 2910 (Combi) automatic analyzer. Blood parameters were determined using the Particle Counter PCE-210 automatic hematology analyzer. RESULTS: The administration of DCA did not significantly affect the life span of rats with C6 glioma. Duration of life of rats, which were administered with MTF only, was significantly higher (by 19.1%, p < 0.01). Combined administration of DCA + MTF prolonged life span of animals with glioma by 50% (p < 0.001). The positive result of antitumor activity of MTF alone and in combination with DCA correlated with a decrease in the mean platelet volume/platelet count (MPV/PLT) ratio by 75.0% (p < 0.05) compared with tumor control. In addition, the expressed antitumor effect of combination therapy with DCA and MTF was associated with a decrease (p < 0.05) in glucose and lactate levels in blood plasma of rats with C6 glioma by 10% and 41.4%, respectively, compared to tumor control. Analysis of blood parameters showed that the growth of C6 glioma was accompanied by the development of leukopenia, anemia and thrombocytopenia. The introduction of DCA caused the correction of manifestations of anemia and leukopenia, but did not affect the level of platelets in the blood of animals with glioma. MTF alone and in combination with DCA positively influenced the number of white blood cells and caused complete thrombocytopenia correction, increasing platelet count by more than 200% (p < 0.001). CONCLUSION: The ability of MTF either used alone or in combination with DCA to influence the development of C6 glioma which is manifested in an increase in the lifespan of rats has been revealed. The most pronounced antitumor effect was recorded against the background of the combined use of these agents, which may be due to their ability to lower the levels of lactate and glucose in the blood of tumor-bearing rats. It is proved that MTF both in monotherapy and in combination with DCA provides correction of anemia and thrombocytopenia, which arise at the background of glioma C6 growth. PMID- 30284995 TI - Anticholinergic Medication Burden in Pediatric Prolonged Critical Illness: A Potentially Modifiable Risk Factor for Delirium. AB - OBJECTIVES: It is important to describe and understand the prevalence and risk factors for the syndrome of delirium in critical illness. Since anticholinergic medication may contribute to the development of delirium in the PICU, we have sought to quantify anticholinergic medication exposure in patients with prolonged admission. We have used Anticholinergic Drug Scale scores to quantify the magnitude or extent of this burden. DESIGN: Retrospective cohort study, January 2011 to December 2015. SETTING: Single academic medical center PICU. PATIENTS: Children under 18 years old with a PICU admission of 15 days or longer, requiring mechanical ventilation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Daily Anticholinergic Drug Scale scores for the first 15 days of admission, in each of 88 subjects (total of 1,320 PICU days), were collected and assessed in relation to demographic data, severity of illness, and medication use. Median (interquartile range) of daily Anticholinergic Drug Scale score was 5 (interquartile range, 3-7). Anticholinergic Drug Scale score was not associated with age, sex, medical history, presenting Severity of Illness score, PICU length of stay, ventilator hours, or hospital mortality. Medications most frequently associated with high Anticholinergic Drug Scale score were low potency anticholinergic drugs such as morphine, midazolam, vancomycin, steroids, and furosemide, with the exception of ranitidine (Anticholinergic Drug Scale score 2). Patients receiving high doses of midazolam infusion had significantly higher Anticholinergic Drug Scale scores compared with those receiving lower or no midazolam dosing. CONCLUSIONS: A high number of medications with anticholinergic effects are administered to PICU patients receiving prolonged mechanical ventilation. These exposures are much higher than those reported in adult intensive care patients. Since anticholinergic drug exposure is associated with delirium, further study of this exposure in PICU patients is needed.

AB - AIM: To study the expression of adhesion markers (E-cadherin, beta-catenin and vimentin) associated with epithelial-mesenchymal transition (EMT) and their role in progression of endometrial carcinoma (EC). MATERIALS AND METHODS: Expression of E-cadherin, beta-catenin and vimentin was studied immunohistochemically in the samples of surgical material of 55 EC patients stage I-III. The proliferation index was determined by flow cytometry. RESULTS: In the group of vimentin negative EC, tumors of low differentiation grade and deep invasion in myometrium as well as high expression of E-cadherin and beta-catenin prevailed compared with the cases with high expression of vimentin. In addition, in EC with high expression of vimentin, an increase in the number of cells with expression of E cadherin in the cytoplasm (78.9 +/- 3.6%) and beta-catenin with cytoplasmic nuclear localization (73.7 +/- 3.2%) was observed compared with these indices in vimentin-negative tumors (45.4 +/- 4.2%, p < 0.001 and 54.5 +/- 2.6%, respectively, p < 0.005), which may indicate EMT-associated changes in EC with high expression of vimentin. CONCLUSIONS: The progression of the endometrioid carcinoma may occur in the setting of various molecular changes, in particular, with decreased expression of E-cadherin and beta-catenin and high expression of vimentin, or in the absence of vimentin, utilizing other mechanisms of regulation of proliferative and metastatic potential. PMID- 30284999 TI - Analysis of the 3'UTR region of the NOTCH1 gene in chronic lymphocytic leukemia patients. AB - : Deregulation of NOTCH1-signalling pathway is common in chronic lymphocytic leukemia (CLL). The most of studies are focused on detection of the hotspot c.7541_7542delCT NOTCH1 mutations in exon 34, while studies of mutations in the 3'UTR region are rare. The aims of work were to evaluate the frequencies of mutations in the 3'UTR region of the NOTCH1 gene (9:136,495553-136,495994) in Ukrainian CLL patients, the distribution of rs3124591 genotypes located in that area, and association of NOTCH1 mutations with structure of B-cell receptor. MATERIALS AND METHODS: Detection of mutations in the 3'UTR region of the NOTCH1 was performed by direct sequencing in 87 previously untreated CLL patients (from the total group of 237 CLL patients) with unmutated immunoglobulin heavy-chain variable (UM IGHV) genes and without mutations in hotspot regions of TP53, SF3B1, and exon 34 of NOTCH1 genes. RESULTS: Mutations in the 3'UTR region of the NOTCH1 were revealed in three of 87 CLL patients (3.4%). Two cases with non-coding mutations were related to subset #1 of stereotyped B-cell receptors, and one case belonged to stereotyped subset #28a. Analysis with inclusion of 30 UM IGHV cases with previously detected c.7544_7545delCT mutations revealed that the frequency of UM IGHV genes of I phylogenetic clan (except IGHV1-69) was significantly increased, and the frequency of UM IGHV3 and IGHV4 genes, on the contrary, was reduced in NOTCH1-mutated cases comparing with NOTCH1-unmutated cases (p = 0.002) and the general group (p = 0.013). SNP rs3124591 did not affect the risk of CLL and survival parameters of the patients. At the same time, differences were found in the frequency of IGHV gene usage and in the structure of HCDR3 in carriers of individual genotypes. CONCLUSION: The frequency of NOTCH1 mutations in 3'UTR region was low. Our findings confirmed current data on the association between the structure of the B-cell receptor and the appearance of NOTCH1 mutations. Some features of HCDR3 structure were identified in carriers of TT and CC genotypes of rs3124591. PMID- 30285000 TI - Yurii Yosypovych Kudryavets (1946-2018).

AB - Adrenocortical cancer is an extremely rare tumor presenting with extensive locoregional spread at the time of diagnosis. Due to the diagnostic difficulties preoperatively and a lack of effective treatment options, patients have poor prognosis. Patients succumb to metastases within a couple of months.

We present a case of a locoregional recurrence of adrenocortical cancer 18 years after left adrenalectomy. PMID- 30285003 TI - Cytotoxic and genotoxic effects of cadmium sulfide nanoparticles. AB - : Cadmium compounds are highly toxic substances characterized by mutagenic, genotoxic and carcinogenic effects, and having high cumulative properties. Application of cadmium nanoparticles (NPs) in medicine stimulates the study of their mechanism of action at the cellular level and at the level of organs and systems, determination of biomarkers of their action, particularly in comparison with the ionic form. The aim of the study was to compare the features of cytotoxic and genotoxic effects of cadmium sulfide (CdS) NPs of different sizes on cell cultures of different histogenesis with those of cadmium chloride (CdCl2). MATERIALS AND METHODS: In this work, we used cadmium compounds in the nanoform: NPs CdS of 4-6 nm and of 9-11 nm in size; and in the ionic form: CdCl2. The studies were conducted in vitro in cell lines - IMR-32, NEK-293 and MAEC. To count viable cells we compared the results of three basic tests: MTT (methyl tetrasolium test), SRB (sulforhodamine B test) and NRU (neutral red uptake test). We evaluated the genotoxic effect of the substances studied in vitro using DNA comet assay in alkaline conditions. RESULTS: CdS NPs and CdCl2 demonstrated pronounced dose-dependent cytotoxic effect in MAEC, NEK-293 and IMR-32 cell lines, by impairing membrane permeability, functioning of mitochondria and lysosomes, and inhibiting the function of protein synthesis. Cytotoxic effect of CdCl2 was the most pronounced, this effect of CdS NPs of 9-11 nm in size being the least pronounced. The comet DNA assay in alkaline conditions revealed a statistically significant increase in DNA comet index when exposed to CdCl2 and CdS NPs in comparison with the negative control, which indicates their genotoxic effect. CdS NPs of 4-6 nm in size showed a more pronounced effect in comparison with those of 9-11 nm in size. CONCLUSION: Elucidation of mechanisms underlying the implementation of toxic effects of cadmium NPs will help in assessing the potential risks associated with their use in industry and developing effective preventive measures. For instance, when planning in vivo studies for toxicological evaluation of nanomaterials and nano-substances containing NPs of cadmium, it is necessary to investigate the mutagenic and carcinogenic risks and to take into account the high likelihood of neurotoxic and cardiovasotoxic effects, along with nephrotoxic effects, since high cytotoxic activity of the investigated compounds of cadmium was detected on the cells of the MAEC line (endothelial origin) and IMR-32 (neuronal origin). PMID- 30285004 TI - ABO blood group and the risk of lung cancer in Greek adults: a case - control study. AB - AIM: The present study aimed to investigate any possible association between ABO blood groups and lung cancer. MATERIALS AND METHODS: The study was conducted on 122 lung cancer patients and 1,255 matched-healthy individuals that were reviewed retrospectively. Chi-square and logistic regression models were used for statistical analysis. RESULTS: No significant difference between lung cancer patients and the control group was recorded regarding ABO blood types and the risk of lung cancer (p = 0.055, OR = 0.79, 95% CI 0.61-1.03). Male gender (p = 0.006, OR = 2.08, 95% CI 1.24-3.49) and smoking (p = 0.000, OR = 3.13, 95% CI 1.72-5.69) were significantly associated with the risk of lung cancer. CONCLUSION: No association between ABO blood types and the risk of lung cancer was observed. PMID- 30285005 TI - The impact of morphine treatment on bladder cancer cell proliferation and apoptosis: in vitro studies. AB - AIM: The aim of this study was to determine the effect of morphine on bladder cancer cell proliferation and apoptosis in vitro. MATERIALS AND METHODS: MTT assay was used to measure percentage growth of RT-112 human bladder cancer cells after 72 hours of morphine/morphine + naloxone treatment. Expression of u-opioid receptors was assessed by Western blot and finally, apoptotic assay with CellEvent Caspase-3/7 Green Detection Reagent was carried out using confocal microscopy. RESULTS: The MTT assays showed that morphine increased RT-112 cell growth. Naloxone inhibited this growth enhancing effect. Western blot analysis regarding u-opioid receptor expression in RT-112 cells remains inconclusive. Morphine was also found to decrease the rate of apoptosis of RT-112 cells, an effect which naloxone inhibited. CONCLUSIONS: This study provides evidence that morphine, at clinically relevant doses, causes RT-112 bladder cancer cell proliferation, possibly opioid receptor mediated and at least some of this effect might be due to decreased apoptosis. Clinically, this suggests that in patients with bladder cancer, managing pain with morphine might have detrimental consequences on patient outcomes and alternative pain relief should be considered if possible. PMID- 30285006 TI - Analysis of the survival of patients with breast cancer depending on age, molecular subtype of tumor and metabolic syndrome. AB - AIM: To analyze the survival of patients with breast cancer (BC) depending on age, molecular subtype of the tumor and the presence of metabolic syndrome. PATIENTS AND METHODS: We have analyzed the results of examination and treatment of 202 patients with BC of stages I-III. The patients were distributed by age into 2 groups. The group 1 included 86 elderly patients (from 65 to 84 years old), the group 2 - 116 younger patients (from 32 to 64 years). An overall 1-, 3- and 5-year survival rates of the treated patients were assessed. The significance of factors influencing the overall survival (OS) of patients with BC was determined using the methods of statistical analysis. RESULTS: Molecular subtype of BC significantly affects survival rates: in a case of a luminal B subtype the 5-year OS was 71.6 vs 80% (p < 0.05) in groups 1 and 2, respectively while in a case of a basal-like subtype it was 60.2% and 71.6% (p < 0.05). The presence of metabolic syndrome significantly reduced the 5-year OS (up to 70.7% and 80.6%, p < 0.05 in groups 1 and 2, respectively). CONCLUSION: The OS is lower in elderly patients with BC compared with younger patients, especially in those who suffer from metabolic syndrome. PMID- 30285007 TI - Paraneoplastic syndrome in lung cancer. AB - AIM: To study the nature of different variants of paraneoplastic syndrome (PNPS) in lung cancer, taking into account the features of the tumorous process and the complications of radiochemotherapy. PATIENTS AND METHODS: We performed an analysis of the data of 1,669 patients with lung cancer aged between 24 and 87 years, among whom there were 89% of men and 11% of women. The ratio of small cell and non-small-cell histological variants of the lung cancer was 1: 4, IB, IIA, IIB, IIIA, IIIB and IV stages of cancer - 1:2:6:58:43:57. RESULTS: PNPS developed in 16% of the lung cancer patients, in these patients we have detected a marked increase in the disease incidence in women, the peripheral form of the tumor, the apical variant of Pancoast - Tobias and adenocarcinoma, but no cases of the median lower localization of the tumor. The number of the upper lobar pathology was decreased, while the severity of the cancer was significantly greater, which more often occurred with exudative pleurisy, germination of the tumor into the chest wall and compression of the upper vena cava. The 21 components of PNPS pathology were established. We distributed them conditionally into the musculoskeletal system lesions, variants of skin vasculitis and autoimmune processes, the nature of which depended on the localization and course of the tumorous process, its histological variation and severity of the course. Moreover, PNPS negatively affected the development of radiochemotherapy complications and worsened survival rate. CONCLUSIONS: The course of PNPS in lung cancer is highly diverse, being a risk factor for a severe tumorous process that worsens the survival of patients. PMID- 30285008 TI - Determination of oxygen perfusion in the area of radiation-induced fibrosis of the skin in patients with breast cancer and its role in pathogenesis of late radiation injury. AB - AIM: Late radiation injury in the form of radiation-induced fibrosis (RIF) is one of the many complications of radiation therapy. The aim was to evaluate oxygen perfusion in the skin in the area of late radiation injury manifested as RIF in patients with breast cancer. MATERIALS AND METHODS: Based on our first-hand experience in treating late radiation injures of soft tissues in patients with breast cancer, we measured oxygen perfusion of the skin (tsrO2) in the area of late radiation injury using a transcutaneous monitor (oximeter) TCM 400 (Radiometer, Denmark). RESULTS: Partial oxygen pressure tcpO2 in the RIF area in patients with breast cancer didn't show any significant decrease compared to healthy tissue. Mean value of partial oxygen pressure tcpO2 in the RIF area was 42.650 +/- 9.178 mmHg, in the healthy tissue it was 45.180 +/- 8.025 mmHg. Maximal difference in tcpO2 between the damaged and healthy tissue was 30 mmHg. CONCLUSIONS: Results of the study suggest that there's no significant difference between oxygen perfusion (tcpO2) in the area of RIF and healthy tissue. PMID- 30285009 TI - Effects of exogenous lactoferrin on phenotypic profile and invasiveness of human prostate cancer cells (DU145 and LNCaP) in vitro. AB - AIM: To investigate the biological effects of exogenous lactoferrin (LF) on phenotypic profile and invasiveness of human prostate cancer (PC) cells in vitro. MATERIALS AND METHODS: Human PC cell lines (LNCaP, DU-145) were cultured with an exogenous LF at a dose corresponding to IC30. The expression levels of steroid hormone receptors (androgen receptor, estrogen receptor, progesterone receptor), Her2/neu, Ki-67, E- and N-cadherin, were monitored by immunohistochemical analysis. The levels of miRNAs were assessed using q-PCR. The invasive activity of the cells was examined in a standard invasion test. RESULTS: Exogenous LF reduced expression of steroid hormone receptors (ERalpha and PR) and Ki-67 in both PC cell lines. The expression of E-cadherin increased significantly in LF treated DU-145 cells. Also, we established the decrease in invasive activity upon LF treatment by 40% and 30% in DU-145 and LNCaP cells, respectively. In DU-145 cells, incubation with exogenous LF resulted in an increase in the expression of oncosuppressive (miR-133a and miR-200b) miRNAs. CONCLUSIONS: Exogenous LF causes the changes in phenotypic characteristics of PC cells and levels of oncogenic and oncosuppressive miRNAs involved in the regulation of key cellular processes. PMID- 30285010 TI - Different morphological structures of breast tumors demonstrate individual drug resistance gene expression profiles. AB - AIM: To identify gene expression profiles involved in drug resistance of different morphological structures (tubular, alveolar, solid, trabecular, and discrete) presented in breast cancer. MATERIAL AND METHODS: Ten patients with luminal breast cancer have been included. A laser microdissection-assisted microarrays and qRT-PCR were used to perform whole-transcriptome profiling of different morphological structures, to select differentially expressed drug response genes, and to validate their expression. RESULTS: We found 27 differentially expressed genes (p < 0.05) encoding drug uptake (SLC1A3, SLC23A2, etc.) and efflux (ABCC1, ABCG1, etc.) transporters, drug targets (TOP2A, TYMS, and Tubb3), and proteins that are involved in drug detoxification (NAT1 and ALDH1B1), cell cycle progression (CCND1, AKT1, etc.), apoptosis (CASP3, TXN2, etc.), and DNA repair (BRCA1 and USP11). Each type of structures showed an individual gene expression profile related to resistance and sensitivity to anticancer drugs. However, most of the genes (19/27; p < 0.05) were expressed in alveolar structures. Functional enrichment analysis showed that drug resistance is significantly associated with alveolar structures. Other structures demonstrated the similar number (10-13 out of 27) of expressed genes; however, the spectrum of resistance and sensitivity to different anticancer drugs varied. CONCLUSION: Different morphological structures of breast cancer show individual expression of drug resistance genes. PMID- 30285012 TI - Comparative histochemical evaluation of mucins expression in fetal esophagus and adenocarcinomas of the gastroesophageal junction. AB - AIM: To study and compare the expression patterns of mucins in the fetal gastroesophageal junction (GEJ) region and adenocarcinomas of the GEJ in adults using histochemical method. MATERIAL AND METHODS: To reveal the expression of different mucins, tissue sections from formalin-fixed paraffin-embedded tissue blocks of fetal GEJ and carcinomas of GEJ were stained by the following histological stains: hematoxylin and eosin, periodic acid-Schiff (PAS), alcian blue (AB), pH 2.5, combined AB-PAS, and combined AB-Aldehyde Fuchsin (AB/AF). RESULTS: Expression of mucins within the developing fetal GEJ has been demonstrated (gestational age 5-38 weeks). We studied histochemical features of neoplastic cells in carcinomas of GEJ from 90 adult patients. The results showed that in gastric type expression of neutral mucins dominated especially in well differentiated (G1) adenocarcinomas and corresponded to the last three months of GEJ development, while in the intestinal and mixed type significant acid mucins expression was detected in moderate (G2) and poorly (G3) differentiated adenocarcinomas and corresponded to 17-25 weeks of GA. No significant coincidence in mucins expression was observed in signet ring cell carcinomas in relation to GA. CONCLUSION: Our data suggest that decrease of neutral mucins level can be considered reliable phenotypic marker of poor prognosis of GEJ adenocarcinomas. Study of the developmental expression of mucin genes may improve understanding of the malignant transformation of esophageal tissue.

AB - AIM: Dendrimers dendritic structural design holds vast promises, predominantly for drug delivery, owing to their unique properties. Dendritic architecture is widespread topology found in nature and offers development of specific properties of chemical substances. Dendrimers are an ideal delivery vehicle candidate for open study of the effects of polymer size, charge, and composition on biologically relevant properties such as lipid bilayer interactions, cytotoxicity, bio-distribution, internalization, blood plasma retention time, and filtration. This article reviews role of dendrimers in advanced drug delivery and biomedical applications. PMID- 30285013 TI - Sterically demanding methoxy and methyl groups in ruthenium complexes lead to enhanced quantum yields for blue light triggered photodissociation. AB - Ruthenium complexes containing a sterically congested metal center can serve as light activated prodrugs through photo-activated chemotherapy (PACT). In this work, we modified PACT agents containing 6,6'-dihydroxybipyridine (6,6'-dhbp) (Papish et al., Inorg. Chem., 2017, 56, 7519) by replacing it with a sterically bulky isoelectronic ligand, 6,6'-dimethoxybipyridine (6,6'-dmbp). The resulting complexes, [(phen)2Ru(6,6'-dmbp)]Cl2 (2OMe, phen = 1,10-phenanthroline) and [(dop)2Ru(6,6'-dmbp)]Cl2 (3OMe, dop = 2,3-dihydro-[1,4]dioxino[2,3 f][1,10]phenanthroline), have been fully characterized and display enhanced quantum yields for blue light triggered photodissociation of 0.024(6) and 0.0030(2), respectively. We have also synthesized 4OH = [(dmphen)2Ru(4,4' dhbp)]Cl2 wherein dmphen = 2,9-dimethyl-1,10-phenanthroline and 4,4'-dhbp = 4,4' dihydroxybipyridine. These ligands enhance steric bulk near the metal center and move the hydroxy groups further from the metal center, respectively. Complex 4OH displays a relatively low quantum yield of 0.0014(2). All of the new complexes (2OMe, 3OMe, 4OH) were tested in breast cancer cells (MDA-MB-231) and were non toxic (IC50 > 100 MUM). This has been interpreted in terms of unfavorable log(Do/w) values and furthermore photodissociation alone is insufficient for cytotoxicity. We also report the crystal structures of 4OH and 2OMe, the thermodynamic acidity of complex 4OH, and the redox potentials for all new complexes. PMID- 30285015 TI - Ru(ii)-Peptide bioconjugates with the cppH linker (cppH = 2-(2' pyridyl)pyrimidine-4-carboxylic acid): synthesis, structural characterization, and different stereochemical features between organic and aqueous solvents. AB - Three new Ru(ii) bioconjugates with the C-terminal hexapeptide sequence of neurotensin, RRPYIL, namely trans,cis-RuCl2(CO)2(cppH-RRPYIL-kappaNp) (7), [Ru([9]aneS3)(cppH-RRPYIL-kappaNp)(PTA)](Cl)2 (8), and [Ru([9]aneS3)Cl(cppH RRPYIL-kappaNp)]Cl (11), where cppH is the asymmetric linker 2-(2' pyridyl)pyrimidine-4-carboxylic acid, were prepared in pure form and structurally characterized in solution. The cppH linker is capable of forming stereoisomers (i.e. linkage isomers), depending on whether the nitrogen atom ortho (No) or para (Np) to the carboxylate on C4 in the pyrimidine ring binds the metal ion. Thus, one of the aims of this work was to obtain pairs of stereoisomeric conjugates and investigate their biological (anticancer, antibacterial) activity. A thorough NMR characterization clearly indicated that in all cases exclusively Np conjugates were obtained in pure form. In addition, the NMR studies showed that, whereas in DMSO-d6 each conjugate exists as a single species, in D2O two (7) or even three if not four (8 and 11) very similar stable species form (each one corresponding to an individual compound). Similar results were observed for the cppH-RRPYIL ligand alone. Overall, the NMR findings are consistent with the occurrence of a strong intramolecular stacking interaction between the phenol ring of tyrosine and the pyridyl ring of cppH. Such stacking interactions between aromatic rings are expected to be stronger in water. This interaction leads to two stereoisomeric species in the free cppH-RRPYIL ligand and in the bioconjugate 7, and is somehow modulated by the less symmetrical Ru coordination environments in 8 and 11, affording three to four very similar species. PMID- 30285014 TI - Chemical micromotors self-assemble and self-propel by spontaneous symmetry breaking. AB - Self-propelling chemical motors have thus far required the fabrication of Janus particles with an asymmetric catalyst distribution. Here, we demonstrate that simple, isotropic colloids can spontaneously assemble to yield dimer motors that self-propel. In a mixture of isotropic titanium dioxide colloids with photo chemical catalytic activity and passive silica colloids, light illumination causes diffusiophoretic attractions between the active and passive particles and leads to the formation of dimers. The dimers constitute a symmetry-broken motor, whose dynamics can be fully controlled by the illumination conditions. Computer simulations reproduce the dynamics of the colloids and are in good agreement with experiments. The current work presents a simple route to obtain large numbers of self-propelling chemical motors from a dispersion of spherically symmetric colloids through spontaneous symmetry breaking. PMID- 30285016 TI - Symmetry-adapted perturbation theory potential for the adenine dimer. AB - A new intermolecular interaction potential for the adenine dimer has been developed with the help of a combination of symmetry-adapted perturbation theory and density functional theory (DFT-SAPT). Supermolecular intermolecular interaction energy computations on hydrogen-bonded and stacked adenine dimers at B3LYP-D, MP2, SCS-MP2, SCS-MI-MP2 and CCSD(T) levels showed that DFT-SAPT is in a very good agreement with CCSD(T). The developed ab initio intermolecular potential has been used to predict the cluster structure of adenine dimers, trimers and tetramers. These global cluster optimizations reproduced adenine dimers reported in the literature and moreover new low-energy structures were also located. For trimers and tetramers, new hydrogen-bonded and stacked low energy structures have also been found. The current findings suggest that the new ab initio potential can further be exploited to reveal the structure and energy of much larger supramolecular adenine clusters. PMID- 30285017 TI - Reviving old protecting group chemistry for site-selective peptide-protein conjugation. AB - Methodologies to conjugate proteins to property-enhancing entities are highly sought after. We report a remarkably simple strategy for conjugating proteins bearing accessible cysteines to unprotected peptides containing a Cys(Scm) protecting group, which is introduced on-resin via a Cys(Acm) building block. The peptides employed for this proof of principle study are highly varied and structurally diverse, and undergo multiple on-resin decoration steps prior to conjugation. The methodology was applied to three different proteins, and proved to be efficient and site-selective. This twist on protecting group chemistry has led to a novel and generally applicable strategy for crossed-disulfide formation between proteins and peptides.

AB - Correction for 'Engineered hydrogen-bonded polymer multilayers: from assembly to biomedical applications' by Georgina K. Such et al., Chem. Soc. Rev., 2011, 40, 19-29. PMID- 30285019 TI - Forcing the 'lazy' protons to work. AB - The combination of cross-polarization (CP) with flip-back (FB) pulse has enabled in NMR the enhancement of 13C sensitivity and the decrease of the recycling delay at both moderate and fast magic-angle spinning (MAS) frequencies. However, only continuous-wave (CW) decoupling is presently compatible with FB-pulse (FB-CW), and depending on the CW radio-frequency (rf) field, either an insignificant sensitivity gain or an acquisition time-dependent gain and a low 13C resolution are obtained. In this study, we propose a new FB-pulse method in which radio frequency-driven recoupling (RFDR) is used as the 1H-13C decoupling scheme to overcome these drawbacks. The performances of FB-RFDR in terms of decoupling efficiency and sensitivity gain are tested on both natural abundance (NA) and uniformly 13C-15N labeled l-histidine.HCl.H2O (Hist) samples at a MAS frequency of nuR = 70 kHz. The results show the superiority of RFDR over the CW decoupling with respect to these criteria. Importantly, they reveal that the sensitivity gain offered by FB-RFDR is nearly independent of the decoupling/acquisition duration. The application of FB-RFDR on NA-Hist and sucrose yields a sensitivity gain between 60 and 100% compared to conventional FB-CW and CPMAS-SPINAL experiments. Moreover, we compare the 13C sensitivities of NA-Hist obtained by our 1D FB-RFDR method and 2D 1H-{13C} double-CP acquisition. Both methods provide similar 13C sensitivity and are complementary. Indeed, the 2D method has the advantage of also providing the 1H-13C spatial proximities, but its sensitivity for quaternary carbons is limited; whereas our 1D FB-RFDR method is more independent of the type of carbon, and can provide a 13C 1D spectrum in a shorter experimental time. We also test the feasibility of FB-RFDR at a moderate frequency of nuR = 20 kHz, but the experimental results demonstrate a poor resolution as well as a negligible sensitivity gain.

AB - The tert-butylethynide ligand has been employed to construct an atomically precise all-tert-butylethynide-protected silver superatom nanocluster, Ag51(tBuC[triple bond, length as m-dash]C)32 (hereafter denoted as Ag51). The identity of Ag51 is confirmed by high resolution ESI-MS and elemental analysis. Single crystal X-ray analysis revealed that the structure of Ag51 features a three-shell arrangement, Ag@Ag8/Ag6@Ag36@C24/C8. Ag51 exhibits a strong solvatochromic effect, and the emissions are strongly dependent on the solvent polarity and are tunable from blue to red by changing the solvent from less polar dichloromethane to highly polar methanol.

The development of aggregation modulators has enormous implications in the discovery of effective therapeutic agents for Alzheimer's disease. Herein, we report the design and synthesis of a series of natural amino acid, l-dopa and dopamine appended derivatives of naphthalenediimide (NDI) to identify efficient aggregation modulators. Furthermore, the molecular docking studies revealed the possible binding sites and binding mode of NDI-conjugates to Abeta aggregates. Among the designed NDI conjugates, l-dopa and dopamine derivatives (NLD and NDP, respectively) showed excellent aggregation modulation efficiency (inhibition and dissolution), as shown by the thioflavin T (ThT) binding assays, dot blot analysis and in cellulo studies. The docking results from in silico studies are in good agreement with the experimental data. In addition to their significant modulation efficiency towards Abeta aggregation, NLD and NDP possess antioxidant activity conducive to the development of disease-modifying therapeutic agents for the treatment of Alzheimer's disease.

AB - Importance: The early obesogenic home environment is consistently identified as a key influence on child weight trajectories, but little research has examined the mechanisms of that influence. Such research is essential for the effective prevention and treatment of overweight and obesity. Objective: To test behavioral susceptibility theory's hypothesis that the heritability of body mass index (BMI) is higher among children who live in more obesogenic home environments. Design, Setting, and Participants: This study was a gene-environment interaction twin study that used cross-sectional data from 925 families (1850 twins) in the Gemini cohort (a population-based prospective cohort of twins born in England and Wales between March and December 2007). Data were analyzed from July to October 2013 and in June 2018. Exposures: Parents completed the Home Environment Interview, a comprehensive measure of the obesogenic home environment in early childhood. Three standardized composite scores were created to capture food, physical activity, and media-related influences in the home; these were summed to create an overall obesogenic risk score. The 4 composite scores were split on the mean, reflecting higher-risk and lower-risk home environments. Main Outcomes and Measures: Quantitative genetic model fitting was used to estimate heritability of age-adjusted and sex-adjusted BMI (BMI SD score, estimated using British 1990 growth reference data) for children living in lower-risk and higher-risk home environments. Results: Among 1850 twins (915 [49.5%] male and 935 [50.5%] female; mean [SD] age, 4.1 [0.4] years), the heritability of BMI SD score was significantly higher among children living in overall higher-risk home environments (86%; 95% CI, 68%-89%) compared with those living in overall lower risk home environments (39%; 95% CI, 21%-57%). The findings were similar when examining the heritability of BMI in the separate food and physical activity environment domains. Conclusions and Relevance: These findings support the hypothesis that obesity-related genes are more strongly associated with BMI in more obesogenic home environments. Modifying the early home environment to prevent weight gain may be particularly important for children genetically at risk for obesity.

AB - Importance: The United States has higher infant and youth mortality rates than other high-income countries, with striking disparities by racial/ethnic group. Understanding changing trends by age and race/ethnicity for leading causes of death is imperative for focused intervention. Objective: To estimate trends in US infant and youth mortality rates from 1999 to 2015 by age group and race/ethnicity, identify leading causes of death, and compare mortality rates with Canada and England/Wales. Design, Setting, and Participants: This descriptive study analyzed death certificate data from the US National Center for Health Statistics, Statistics Canada, and the UK Office of National Statistics for all deaths among individuals younger than 25 years. The study took place from January 1, 1999, to December 31, 2015, and analyses started in September 2017. Exposures: Race/ethnicity. Main Outcomes and Measures: Average annual percent changes in mortality rates from 1999 to 2015 and absolute rate change between 1999 to 2002 and 2012 to 2015 for each age group, race/ethnicity, and cause of death. Results: Among individuals from birth to age 24 years, 1 169 537 deaths occurred in the United States, 80 540 in Canada, and 121 183 in England/Wales from 1999 to 2015. In the United States, 64% of deaths occurred in male individuals and 52.6% occurred in white individuals (25.1% deaths occurred in black individuals and 17.9% in Latino individuals). All-cause mortality declined for all age groups (infants younger than 1 year [38.5% of deaths], children aged 1-9 years [10.6%], early adolescents aged 10-14 years [5%], late adolescents aged 15-19 years [17.7%], and young adults aged 20-24 years [28.1%]) in the United States, Canada, and England/Wales from 1999 to 2015. However, rates were highest in the United States. Within the United States, annual declines in all-cause mortality rates occurred among all age groups of black, Latino, and white individuals, except for white individuals aged 20 to 24 years, whose rates remained stable. Mortality rates declined across most major causes of death from 1999 to 2002 and 2012 to 2015, with notable declines observed for sudden infant death syndrome, unintentional injury death, and homicides. Among infants, unintentional suffocation and strangulation in bed increased (difference between 2012-2015 and 1999-2002 range, 6.11-29.03 per 100 000). Further, suicide rates among Latino and white individuals aged 10 to 24 years (range, 0.21-2.63 per 100 000) and black individuals aged 10 to 19 years (range, 0.10-0.45 per 100 000) increased, as did unintentional injury deaths in white young adults (0.79 per 100 000). The rise in unintentional injury deaths is attributed to increases in drug poisonings and was also observed in black and Latino young adults. Conclusions and Relevance: Mortality rates in the United States have generally declined for infants and youths from 1999 to 2015 owing to reductions in sudden infant death syndrome, unintentional injury death, and homicides. However, US mortality rates remain higher than Canada and England/Wales, with particularly elevated rates among black and American Indian/Alaskan Native youth. Further, there is a concerning increase in suicide and drug poisoning death rates among US adolescents and young adults. PMID- 30285035 TI - Disclosures Can Always Be Improved.

PMID- 30285041 TI - Association of Risk for Venous Thromboembolism With Use of Low-Dose Extended- and Continuous-Cycle Combined Oral Contraceptives: A Safety Study Using the Sentinel Distributed Database. AB - Importance: Continuous/extended cyclic estrogen use (84/7 or 365/0 days cycles) in combined oral contraceptives (COCs) could potentially expose women to an increased cumulative dose of estrogen, compared with traditional cyclic regimens (21/7 days cycle), and may increase the risk for venous thromboembolism (VTE). Objective: To determine, while holding the progestogen type constant, whether the risk for VTE is higher with use of continuous/extended COCs than with cyclic COCs among women who initiated a COC containing ethinyl estradiol and levonorgestrel. Design, Setting, and Participants: Incident user retrospective cohort study of primarily commercially insured US population identified from the Sentinel Distributed Database. Participants were women aged 18 to 50 years at the time of initiating a study COC between May 2007 and September 2015. Using a propensity score approach and Cox proportional hazards regression models, we estimated the hazard ratios of VTE overall and separately by ethinyl estradiol dose and age groups. Exposures: Initiation of continuous/extended or traditional cyclic COCs containing ethinyl estradiol or levonorgestrel of any dose. Main Outcomes and Measures: First VTE hospitalization that occurred during the study follow-up, identified by an inpatient International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code of 415.1, 415.1x, 453, 453.x, or 453.xx. Results: We identified 210 691 initiators of continuous/extended COCs (mean [SD] age, 30.4 [8.6] years) and 522 316 initiators of cyclic COCs (mean [SD] age, 28.8 [8.3] years), with a mean of 0.7 person-years at risk among continuous/extended and cyclic users. Baseline cardiovascular and metabolic conditions (7.2% vs 4.7%), gynecological conditions (39.7% vs 32.3%), and health services utilization were slightly higher among continuous/extended cyclic than cyclic COC users. Propensity score matching decreased the hazard ratio estimates from 1.84 (95% CI, 1.53-2.21) to 1.32 (95% CI, 1.07-1.64) for continuous/extended use compared with cyclic COC use. The absolute risk difference (0.27 per 1000 persons) and the incidence rate difference (0.35 cases per 1000 person-years [1.44 vs 1.09 cases per 1000 person-years]) between the 2 propensity score matched cohorts remained low, which may not translate into a clinically significant risk differences between cyclic and noncyclic estrogen use. Conclusions and Relevance: Holding the progestogen type constant (levonorgestrel), we observed a slightly elevated VTE risk in association with continuous/extended COC use when compared with cyclic COC use. However, due to the small absolute risk difference and potential residual confounding, our findings did not show strong evidence supporting a VTE risk difference between continuous/extended and cyclic COC use. PMID- 30285042 TI - Effect of Increased Daily Water Intake in Premenopausal Women With Recurrent Urinary Tract Infections: A Randomized Clinical Trial. AB - Importance: Increased hydration is often recommended as a preventive measure for women with recurrent cystitis, but supportive data are sparse. Objective: To assess the efficacy of increased daily water intake on the frequency of recurrent cystitis in premenopausal women. Design, Setting, and Participants: Randomized, open-label, controlled, 12-month trial at a clinical research center (years 2013 2016). Among 163 healthy women with recurrent cystitis (>=3 episodes in past year) drinking less than 1.5 L of fluid daily assessed for eligibility, 23 were excluded and 140 assigned to water or control group. Assessments of daily fluid intake, urinary hydration, and cystitis symptoms were performed at baseline, 6- and 12-month visits, and monthly telephone calls. Interventions: Participants were randomly assigned to drink, in addition to their usual fluid intake, 1.5 L of water daily (water group) or no additional fluids (control group) for 12 months. Main Outcomes and Measures: Primary outcome measure was frequency of recurrent cystitis over 12 months. Secondary outcomes were number of antimicrobial regimens used, mean time interval between cystitis episodes, and 24 hour urinary hydration measurements. Results: The mean (SD) age of the 140 participants was 35.7 (8.4) years, and the mean (SD) number of cystitis episodes in the previous year was 3.3 (0.6). During the 12-month study period, the mean (SD) number of cystitis episodes was 1.7 (95% CI, 1.5-1.8) in the water group compared with 3.2 (95% CI, 3.0-3.4) in the control group, with a difference in means of 1.5 (95% CI, 1.2-1.8; P < .001). Overall, there were 327 cystitis episodes, 111 in the water group and 216 in the control group. The mean number of antimicrobial regimens used to treat cystitis episodes was 1.9 (95% CI, 1.7-2.2) and 3.6 (95% CI, 3.3-4.0), respectively, with a difference in means of 1.7 (95% CI, 1.3-2.1; P < .001). The mean time interval between cystitis episodes was 142.8 (95% CI, 127.4-160.1) and 84.4 (95% CI, 75.4-94.5) days, respectively, with a difference in means of 58.4 (95% CI, 39.4-77.4; P < .001). Between baseline and 12 months, participants in the water group, compared with those in the control group, had increased mean (SD) urine volume (1.4 [0.04] vs 0.1 [0.04] L; P < .001) and voids (2.4 [0.2] vs -0.1 [0.2]; P < .001) and decreased urine osmolality (-402.8 [19.6] vs -24.0 [19.5] mOsm/kg; P < .001). Conclusions and Relevance: Increased water intake is an effective antimicrobial-sparing strategy to prevent recurrent cystitis in premenopausal women at high risk for recurrence who drink low volumes of fluid daily.

AB - Importance: Dementia is common in Parkinson disease, but few data exist on dementia treatment patterns or the concurrent use of acetylcholinesterase inhibitors (ACHEIs) and anticholinergic medications, a frank prescribing error. Objectives: To describe dementia treatment patterns, and to determine the extent to which the concurrent use of ACHEIs and drugs with strong anticholinergic activity occurs among individuals with Parkinson disease in the United States. Design, Setting, and Participants: This cross-sectional analysis included adult Medicare beneficiaries (aged 65 years or older) with Parkinson disease diagnosis with 12 consecutive months of inpatient, outpatient, and prescription drug coverage from January 1, 2014, through December 31, 2014. Beneficiaries with other parkinsonian syndromes were excluded. Demographic, geographic, prescription claims, and other data were extracted from the 2014 Carrier, Beneficiary Summary, and Prescription Drug Event research identifiable files of the Centers for Medicare & Medicaid Services. Data analysis was conducted from August 1, 2017, to November 30, 2017. Main Outcomes and Measures: Primary outcomes were use of dementia drug, specific dementia medication, and concurrent exposure to a high potency anticholinergic drug and an ACHEI. Descriptive analyses and multivariable logistic regression models determined the extent to which patient characteristics and comorbid conditions were associated with dementia treatment or with a high potency anticholinergic and ACHEI never event. Results: Of 268 407 Medicare beneficiaries with Parkinson disease (mean [SD] age, 78.9 [7.5]; 134 575 male [50.1%]), most were identified in the files as white (232 831 [86.7%]), followed by black (14 629 [5.5%]), Hispanic (7176 [2.7%]), Asian (7115 [2.7%]), and Native American (874 [0.3%]). Among these beneficiaries, 73 093 (27.2%) were given a prescription for at least 1 antidementia medication. The most commonly prescribed medication was donepezil hydrochloride (46 027 [63.0%] users), followed by memantine hydrochloride (30 578 [41.8%] users) and rivastigmine tartrate (19 278 [26.4%] users). Dementia drugs were more likely to be prescribed to black (adjusted odds ratio [AOR], 1.33; 95% CI, 1.28-1.38) and Hispanic (AOR, 1.28; 95% CI, 1.22-1.35) beneficiaries and less likely for Native American beneficiaries (AOR, 0.62; 95% CI, 0.51-0.74). Women were less likely than men to be given a prescription for dementia medication (AOR, 0.85; 95% CI, 0.84-0.87). Of the 64 017 beneficiaries receiving an ACHEI, 28 495 (44.5%) experienced at least 1 high potency anticholinergic-ACHEI event. Hispanic (AOR, 1.11; 95% CI, 1.00-1.23) and women (AOR, 1.30; 95% CI, 1.25-1.35) beneficiaries had greater odds of experiencing this never event. Statistically significant clusters of the prevalence of this prescribing error were observed across the United States (Moran I = 0.24; P < .001), with clusters of high prevalence in the southern and midwestern states. Conclusions and Relevance: Dementia medication use by persons with Parkinson disease varies by race/ethnicity and sex; potentially inappropriate prescribing is common among those being treated for cognitive impairment and varies by race/ethnicity, sex, and geography. These findings may serve as national and local targets for improving care quality and outcomes for persons with Parkinson disease.

PMID- 30285049 TI - Persistence and Drivers of High-Cost Status Among Dual-Eligible Medicare and Medicaid Beneficiaries: An Observational Study. AB - Background: Little is known about the persistence of high-cost status among dual eligible Medicare and Medicaid beneficiaries, who account for a substantial proportion of expenditures in both programs. Objective: To determine what proportion of this population has persistently high costs. Design: Observational study. Setting: Medicare-Medicaid Linked Enrollee Analytic Data Source data for 2008 to 2010. Participants: 1 928 340 dual-eligible Medicare and Medicaid beneficiaries who were alive all 3 years. Measurements: Medicare and Medicaid payments for these beneficiaries were calculated for each year. Beneficiaries were categorized as high-cost for a given year if their spending was in the top 10% for that year. Differences in spending were then examined for those who were persistently high-cost (all 3 years) versus those who were transiently high-cost (2008 but not 2009 or 2010) and those who were non-high-cost in all 3 years. Results: In the first year, 192 835 patients were high-cost. More than half (54.8%) remained high-cost across all 3 years. These patients were younger than transiently high-cost patients, with fewer medical comorbidities and greater intellectual impairment. Persistently high-cost patients spent $161 224 per year compared with $86 333 per year for transiently high-cost patients and $22 352 per year for non-high-cost patients. Most of the spending among persistently high cost patients (68.8%) was related to long-term care, and very little (<1%) was related to potentially preventable hospitalizations for ambulatory care-sensitive conditions. Limitation: Potential misclassification of preventable spending and lack of detailed clinical data in administrative claims. Conclusion: A substantial majority of high-cost dual-eligible beneficiaries had persistently high costs over 3 years, with most of the cost related to long-term care and very little related to potentially preventable hospitalizations.

PMID- 30285053 TI - Fibromuscular Dysplasia and Its Neurologic Manifestations: A Systematic Review. AB - Importance: Data on neurologic manifestations of fibromuscular dysplasia (FMD) are rare, and current knowledge remains limited. Objectives: To present a comprehensive review of the epidemiologic characteristics, management, and prognosis of the neurologic manifestations associated with cerebrovascular FMD (ie, involving cervical or intracranial arteries) and to guide future research priorities. Evidence Review: References were identified through searches of PubMed from inception to December 2017 using both the medical subject headings and text words. Additional sources were also identified by reviewing reference lists of relevant articles and through searches of the authors' personal files. Selected articles described at least 1 clinical or radiologic feature and/or outcome of cerebrovascular FMD. Isolated case reports could be included if they described interesting or noteworthy manifestations of FMD. Findings: A total of 84 relevant references were identified. Diagnosis of cerebrovascular FMD is based on the appearance of alternating arterial dilatation and constriction ("string of beads") or of focal narrowing, with no sign of atherosclerotic or inflammatory lesions. Although the diagnosis is easily apparent on results of radiographic imaging, making a diagnosis can be challenging in children or individuals with atypical phenotypes, such as purely intracranial FMD and arterial diaphragm. Involvement of multiple arteries is common, and there is increased incidence of cervical artery dissection and intracranial aneurysms. A variant in the PHACTR1 gene has been associated with FMD as well as cervical artery dissection and migraine, although less than 5% of cases of FMD are familial. Headaches, mainly of the migraine type, are observed in up to 70% of patients with FMD. Cerebrovascular FMD is mostly asymptomatic, but the most frequent neurologic manifestations include transient ischemic attack and ischemic stroke, notably in the presence of associated cervical artery dissection. Other conditions associated with FMD include subarachnoid hemorrhage and, rarely, intracranial hemorrhage. Management relies on observational data and expert opinion. Antiplatelet therapy is considered reasonable to prevent thromboembolic complications. Endovascular therapy is typically restricted to cases with symptomatic stenosis despite optimal medical therapy or in those with rupture of an intracranial aneurysm. Conclusions and Relevance: Longitudinal cohort studies of individuals of multiple ethnicities with biosampling are needed to better understand the risk factors, pathophysiological features, and outcomes of FMD. Patient advocacy groups could assist researchers in answering patient-centered questions regarding FMD. PMID- 30285054 TI - Efficacy of Low-Dose Amitriptyline for Chronic Low Back Pain: A Randomized Clinical Trial. AB - Importance: Antidepressants at low dose are commonly prescribed for the management of chronic low back pain and their use is recommended in international clinical guidelines. However, there is no evidence for their efficacy. Objective: To examine the efficacy of a low-dose antidepressant compared with an active comparator in reducing pain, disability, and work absence and hindrance in individuals with chronic low back pain. Design, Setting, and Participants: A double-blind, randomized clinical trial with a 6-month follow-up of adults with chronic, nonspecific, low back pain who were recruited through hospital/medical clinics and advertising was carried out. Intervention: Low-dose amitriptyline (25 mg/d) or an active comparator (benztropine mesylate, 1 mg/d) for 6 months. Main Outcomes and Measures: The primary outcome was pain intensity measured at 3 and 6 months using the visual analog scale and Descriptor Differential Scale. Secondary outcomes included disability assessed using the Roland Morris Disability Questionnaire and work absence and hindrance assessed using the Short Form Health and Labour Questionnaire. Results: Of the 146 randomized participants (90 [61.6%] male; mean [SD] age, 54.8 [13.7] years), 118 (81%) completed 6-month follow-up. Treatment with low-dose amitriptyline did not result in greater pain reduction than the comparator at 6 (adjusted difference, -7.81; 95% CI, -15.7 to 0.10) or 3 months (adjusted difference, -1.05; 95% CI, -7.87 to 5.78), independent of baseline pain. There was no statistically significant difference in disability between the groups at 6 months (adjusted difference, -0.98; 95% CI, -2.42 to 0.46); however, there was a statistically significant improvement in disability for the low-dose amitriptyline group at 3 months (adjusted difference, -1.62; 95% CI, -2.88 to -0.36). There were no differences between the groups in work outcomes at 6 months (adjusted difference, absence: 1.51; 95% CI, 0.43-5.38; hindrance: 0.53; 95% CI, 0.19-1.51), or 3 months (adjusted difference, absence: 0.86; 95% CI, 0.32-2.31; hindrance: 0.78; 95% CI, 0.29-2.08), or in the number of participants who withdrew owing to adverse events (9 [12%] in each group; chi2 = 0.004; P = .95). Conclusions and Relevance: This trial suggests that amitriptyline may be an effective treatment for chronic low back pain. There were no significant improvements in outcomes at 6 months, but there was a reduction in disability at 3 months, an improvement in pain intensity that was nonsignificant at 6 months, and minimal adverse events reported with a low-dose, modest sample size and active comparator. Although large-scale clinical trials that include dose escalation are needed, it may be worth considering low-dose amitriptyline if the only alternative is an opioid.

PMID- 30285055 TI - Divergent Long-Term Detection Rates of Proximal and Distal Advanced Neoplasia in Fecal Immunochemical Test Screening Programs: A Retrospective Cohort Study. AB - Background: Short-term studies have reported that the fecal immunochemical test (FIT) is less accurate in detecting proximal than distal colorectal neoplasia. Objective: To assess the long-term detection rates for advanced adenoma and colorectal cancer (CRC), according to anatomical location. Design: Retrospective study. Setting: Population-based, organized screening program in the Veneto region of Italy. Participants: Persons aged 50 to 69 years who completed 6 rounds of FIT screening. Measurements: At each screening round, the detection rates for advanced adenoma and cancer, as well as the proportional interval cancer rate (PICR), were calculated by anatomical location (proximal colon, distal colon, or rectum). Results: Between 2002 and 2014, a total of 123 347 participants had 441 647 FITs. The numbers of advanced adenomas and cancer cases detected, respectively, were 1704 and 200 in the proximal colon, 3703 and 324 in the distal colon, and 1220 and 209 in the rectum. Although the detection rate for proximal colon cancer declined only from the first to the second screening round (0.63 to 0.36 per 1000 screenees), the rate for both distal colon and rectal cancer steadily decreased across 6 rounds (distal colon, 1.65 in the first round to 0.17 in the sixth; rectum, 0.82 in the first round to 0.17 in the sixth). Similar trends were found for advanced adenoma (proximal colon, 5.32 in the first round to 4.22 in the sixth; distal colon, 15.2 in the first round to 5.02 in the sixth). Overall, 150 cases of interval cancer were diagnosed. The PICR was higher in the proximal colon (25.2% [95% CI, 19.9% to 31.5%]) than the distal colon (6.0% [CI, 3.9% to 8.9%]) or rectum (9.9% [CI, 6.9% to 13.7%]). Limitations: Participants with irregular attendance were censored. Those who had a false positive result on a previous FIT but negative colonoscopy results were included in subsequent rounds. Conclusion: This FIT-based, multiple-round, long-term screening program had a negligible reduction in detection rates for neoplastic lesions in the proximal versus the distal colon after the first round. This was related to a higher PICR in the proximal colon and suboptimal efficacy in preventing the age-related proximal shifting of CRC. Primary Funding Source: None. PMID- 30285056 TI - Association of Age at Onset and Longitudinal Course of Prefrontal Function in Youth With Schizophrenia. AB - Importance: The extent of cognitive deterioration after schizophrenia (SZ) onset is poorly understood because prior longitudinal studies used small samples of older individuals with established illness. Objective: To examine the association of age at onset and subsequent longitudinal course of prefrontal activity during the first 2 years of illness in youths with SZ and healthy control participants (HCs). Design, Setting, and Participants: This naturalistic, longitudinal, functional magnetic resonance imaging (fMRI) study included patients with recent onset SZ and HCs aged 12 to 25 years enrolled in an ongoing study of cognition in recent-onset psychosis in the Sacramento, California, area from October 13, 2004, through June 25, 2013. Participants completed clinical assessments and an established measure of cognitive control, the AX Continuous Performance Task (AX CPT), during fMRI at baseline and at 6-, 12-, and 24-month follow-up. Whole brain, voxelwise, and an a priori dorsolateral prefrontal cortex (DLPFC) region of interest analyses were performed. Group differences in developmental trajectories were examined by focusing on behavioral performance (d'-context) and cognitive control-associated brain activity. The association of antipsychotic medication and clinical factors were also examined. Data were analyzed from April 15, 2015, through August 29, 2017. Main Outcomes and Measures: Primary outcomes included group differences (HC vs SZ) in behavioral performance (d'-context from AX-CPT) and brain activity for cue B-A trials of the AX-CPT in an a priori DLPFC region of interest at baseline and across the age span. Secondary analysis examined the influence of antipsychotics on behavioral performance and DLPFC activity. Results: Among the sample of 180 participants (66.1% male; mean [SD] age at baseline, 19.2 [3.2] years), 87 patients with SZ (mean [SD] age, 19.6 [3.0] years) showed impaired performance compared with 93 HCs (mean [SD] age, 18.8 [3.4] years) across the age span (estimated difference [SE], -0.571 [0.12], d'-context; P < .001). Patients with SZ showed reduced activation in the DLPFC and parietal cortex (false discovery rate cluster corrected to P < .05) compared with HCs under conditions of high cognitive control at baseline. Region-of interest analysis showed reduced activation in the DLPFC bilaterally for patients with SZ, with a trajectory that paralleled that of HCs across the age span (left DLPFC beta [SE] estimates, 0.409 [0.165] for the HC group and -0.285 [0.130] for the SZ group [main effect of group, P = .03]; right DLPFC beta [SE] estimates, 0.350 [0.103] for the HC group and -0.469 [0.157] for the SZ group [P = .003]). Antipsychotic medication, clinical symptoms, and global functioning were associated with SZ performance. Conclusions and Relevance: During the initial 1 to 2 years after illness onset, young individuals with SZ showed deficits in DLPFC activation and cognitive control, with developmental trajectories comparable to those of HCs. Younger age at onset was not associated with reduced cognition or activation. For individuals contributing to longitudinal analysis, results suggest that young patients do not show deterioration or disruption of ongoing brain development in the initial years after illness onset. PMID- 30285057 TI - Association of Initially Normal Coronary Arteries With Normal Findings on Follow up Echocardiography in Patients With Kawasaki Disease. AB - Importance: American Heart Association guidelines recommend echocardiography in Kawasaki disease at baseline, 1 to 2 weeks, and 4 to 6 weeks after treatment to detect coronary artery abnormalities. However, these examinations are expensive and may require sedation in young children, which is burdensome and carries some risk. Objective: To assess the benefit of additional echocardiographic imaging at 6 weeks in patients with uncomplicated Kawasaki disease who had previously normal coronary arteries. Design, Setting, and Participants: This is a retrospective review of patients with Kawasaki disease who were cared for between 1995 and 2014 in 2 academic pediatric referral practices Eligibility criteria included receiving intravenous immunoglobulin treatment for acute Kawasaki disease at a center; the absence of significant congenital heart disease; available echocardiographic measurements of both the right and left anterior descending coronary arteries at 10 days or less after diagnosis (baseline), 2 (+/-1) weeks, and 6 (+/-3) weeks of illness; and normal coronary arteries at baseline and 2 weeks, defined as maximum coronary artery z scores less than 2.0 and no distal aneurysms. Data analysis was completed from March 2015 to November 2015. Main Outcomes and Measures: The number of patients with right coronary artery or left anterior descending coronary artery z scores of 2.0 or more at 6 weeks. Results: The median age of the 464 included patients was 3.3 years (interquartile range, 1.8-5.4 years); 264 (56.9%) were male, 351 of 414 for whom data were available (84.8%) had complete Kawasaki disease, and 66 (14.2%) received additional intravenous immunoglobulin treatment. At 6 weeks of illness, 456 patients (98.3%) who had had normal coronary artery z scores at baseline and 2 weeks continued to have normal z scores. Of the remaining 8 patients (1.7%), the maximum z score within 6 weeks was 2.0 to 2.4 in 5 patients (1.2%), 2.5 to 2.9 in 1 patient (0.2%), and 3.0 or more in 2 patients (0.4% [95% CI, 0.1%-1.5%]). Coronary artery dimensions ultimately normalized in all but 1 patient, who had minimal dilation at 6 weeks (right coronary artery z score, 2.1). Sensitivity analyses using less restrictive cut points (eg, a maximum z score <2.5) or less restrictive timing windows (eg, considering patients with incomplete echocardiographic data within 21 days) gave similar results; in these analyses, 454 to 463 of 464 patients (98% to 99.7%) had coronary artery z scores of less than 2.5 at 6 weeks. Conclusions and Relevance: New abnormalities in coronary arteries are rarely detected at 6 weeks in patients with Kawasaki disease who have normal measurements at baseline and 2 weeks of illness, suggesting that the 6-week echocardiographic imaging may be unnecessary in patients with uncomplicated Kawasaki disease and z scores less than 2.0 in the first 2 weeks of illness.

AB - Importance: The natural history and the management of patients with asymptomatic aortic stenosis (AS) have not been fully examined in the current era. Objective: To determine the clinical outcomes of patients with asymptomatic AS using data from the Heart Valve Clinic International Database. Design, Setting, and Participants: This registry was assembled by merging data from prospectively gathered institutional databases from 10 heart valve clinics in Europe, Canada, and the United States. Asymptomatic patients with an aortic valve area of 1.5 cm2 or less and preserved left ventricular ejection fraction (LVEF) greater than 50% at entry were considered for the present analysis. Data were collected from January 2001 to December 2014, and data were analyzed from January 2017 to July 2018. Main Outcomes and Measures: Natural history, need for aortic valve replacement (AVR), and survival of asymptomatic patients with moderate or severe AS at entry followed up in a heart valve clinic. Indications for AVR were based on current guideline recommendations. Results: Of the 1375 patients included in this analysis, 834 (60.7%) were male, and the mean (SD) age was 71 (13) years. A total of 861 patients (62.6%) had severe AS (aortic valve area less than 1.0 cm2). The mean (SD) overall survival during medical management (mean [SD] follow up, 27 [24] months) was 93% (1%), 86% (2%), and 75% (4%) at 2, 4, and 8 years, respectively. A total of 104 patients (7.6%) died under observation, including 57 patients (54.8%) from cardiovascular causes. The crude rate of sudden death was 0.65% over the duration of the study. A total of 542 patients (39.4%) underwent AVR, including 388 patients (71.6%) with severe AS at study entry and 154 (28.4%) with moderate AS at entry who progressed to severe AS. Those with severe AS at entry who underwent AVR did so at a mean (SD) of 14.4 (16.6) months and a median of 8.7 months. The mean (SD) 2-year and 4-year AVR-free survival rates for asymptomatic patients with severe AS at baseline were 54% (2%) and 32% (3%), respectively. In those undergoing AVR, the 30-day postprocedural mortality was 0.9%. In patients with severe AS at entry, peak aortic jet velocity (greater than 5 m/s) and LVEF (less than 60%) were associated with all-cause and cardiovascular mortality without AVR; these factors were also associated with postprocedural mortality in those patients with severe AS at baseline who underwent AVR (surgical AVR in 310 patients; transcatheter AVR in 78 patients). Conclusions and Relevance: In patients with asymptomatic AS followed up in heart valve centers, the risk of sudden death is low, and rates of overall survival are similar to those reported from previous series. Patients with severe AS at baseline and peak aortic jet velocity of 5.0 m/s or greater or LVEF less than 60% have increased risks of all-cause and cardiovascular mortality even after AVR. The potential benefit of early intervention should be considered in these high-risk patients.

AB - Importance: The nationwide fecal immunochemical test-based screening program has influenced surgical care for patients with colorectal cancer (CRC) in the Netherlands, although these implications have not been studied in much detail so far. Objective: To compare surgical outcomes of patients diagnosed as having CRC through the fecal immunochemical test-based screening program (screen detected) and patients with non-screen-detected CRC. Design, Setting, and Participants: This was a population-based comparative cohort study using the Dutch ColoRectal Audit and analyzed all Dutch hospitals performing CRC resections. Patients who underwent elective resection for CRC between January 2011 to December 2016 were included. Interventions: Colorectal cancer surgery. Main Outcomes and Measures: Postoperative nonsurgical complications, postoperative surgical complications, postoperative 30-day or in-hospital mortality, and complicated course (postoperative complication resulting in a hospital stay >14 days and/or a reintervention and/or mortality). A risk-stratified comparison was made for different postoperative outcomes based on screening status (screen detected vs not screen detected), cancer stage (I-IV), and for cancer stage I to III also on age (aged <=70 years and >70 years) and American Society of Anesthesiologists score (I-II and III-IV). To determine any residual case-mix-corrected differences in outcomes between patients with screen-detected and non-screen-detected cancer, univariable and multivariable logistic regression analyses were performed. Results: In total, 36 242 patients with colon cancer and 17 416 patients with rectal cancer were included for analysis. Compared with patients with non-screen detected CRC, screen-detected patients were younger (mean [SD] age, 68 [5] vs 70 [11] years), more often men (3777 [60%] vs 13 506 [57%]), and had lower American Society of Anesthesiologists score (American Society of Anesthesiologists score III+: 838 [13%] vs 5529 [23%]). Patients with stage I to III colon cancer who were screen detected had a significantly lower mortality and complicated course rate compared with non-screen-detected patients. For patients with rectal cancer, only a significant difference was found in mortality rate in patients with a cancer stage IV disease, which was higher in the screen-detected group. Compared with non-screen-detected colon cancer, an independent association was found for screen-detected colon cancer on nonsurgical complications (adjusted odds ratio, 0.81; 95% CI, 0.73-0.91), surgical complications (adjusted odds ratio, 0.80; 95% CI, 0.72-0.89), and complicated course (adjusted odds ratio, 0.80; 95% CI, 0.71 0.90). Screen-detected rectal cancer had significantly higher odds on mortality. Conclusions and Relevance: Postoperative outcomes were significantly better for patients with colon cancer referred through the fecal immunochemical test-based screening program compared with non-screen-detected patients. These differences were not found in patients with rectal cancer. The outcomes of patients with screen-detected colon cancer were still better after an extensive case-mix correction, implying additional underlying factors favoring patients referred for surgery through the screening program.

PMID- 30285066 TI - Establishing Pediatric and Adult RBC Reference Intervals With NHANES Data Using Piecewise Regression. AB - Objectives: To develop age- and sex-specific RBC reference intervals using the National Health and Nutrition Examination Survey (NHANES) 1999 to 2012, a large nationally representative, population-based, cross-sectional database (n = 44,328). Methods: Comprehensive medical data were used to define a "healthy" population. Reference intervals for RBC count, hemoglobin, hematocrit, mean cell hemoglobin, mean cell hemoglobin concentration, mean cell volume, and red cell distribution width were computed using piecewise regression, an evidence-based statistical procedure that identifies breakpoints. Results: The derived reference intervals were sex specific, unlike many current standards, and more precise for individuals of different ages, especially for children, adolescents, and elderly individuals, as additional breakpoints were detected for these groups. Suggested reference values for hematocrit and hemoglobin of older adult males were substantially lower than current values. Conclusions: The reference intervals provided here, based on a large, nationally representative healthy population, contribute to the ongoing transition to precision medicine. PMID- 30285067 TI - HLA-Mediated Platelet Refractoriness: An ACLPS Critical Review. AB - Objectives: To provide an overview of the complexities associated with the human leukocyte antigen (HLA)-mediated platelet refractoriness. HLA antibody detection technologies and limitations associated with methodologies are discussed. Methods: A case scenario and review of relevant literature describing platelet refractoriness are presented, followed by a discussion of HLA antibody testing. Results: Following diagnosis of HLA-mediated refractoriness, a decision is made regarding the approach to obtain the appropriate platelets. The panel reactive antibodies (PRA) % of the patient, HLA typing, and limitations of the HLA testing should be taken into account when deciding which type of product would be the best option for a given patient. Conclusions: Following confirmation and review of HLA antibody testing, platelets are ordered based upon the PRA% and approach employed, HLA-matched platelets, antigen restricted platelets, or cross-matched platelets. The platelets are transfused and a posttransfusion increment count is monitored to determine transfusion success. PMID- 30285068 TI - Unexpectedly High Prevalence of Cystoisospora belli Infection in Acalculous Gallbladders of Immunocompetent Patients. AB - Objectives: Indications for cholecystectomy have changed dramatically over the past three decades. Cystoisospora belli has been reported in cholecystectomy specimens of immunocompetent patients. The present study was designed to determine the prevalence and clinical association of C belli in the gallbladder. Methods: The study included retrospective review of cholecystectomy specimens (n = 401) removed for various indications, and a prospective cohort of cholecystectomy specimens (n = 22) entirely submitted for histologic evaluation. Correlations of presence of C belli with age, sex, clinical indication, and abnormalities of preoperative laboratory values were assessed by Fisher exact test. Results: C belli was identified in 39/401 (9.7%) of the retrospective cohort, and 6/22 (27.3%) of the entirely submitted specimens. The presence of C belli showed no correlation with age, sex, clinical indication, or laboratory abnormalities. Conclusions: C belli resides in a latent state in the gallbladder and may be best considered a commensal organism. PMID- 30285069 TI - Efficacy and Safety of Antibiotic Therapy in Early Cutaneous Lyme Borreliosis: A Network Meta-analysis. AB - Importance: Controversies about the choice of antibiotic agent and treatment modality exist in the management of erythema migrans in early cutaneous Lyme borreliosis (LB). Objective: To conduct a network meta-analysis (NMA) of all randomized clinical trials on various antibiotic agents and treatment modalities in early cutaneous LB. Data Sources: Electronic searches in MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were conducted from inception until July 2017. The reference lists of the included studies were hand searched, authors were contacted, and ongoing trials were searched at ClinicalTrials.gov. Study Selection: One reviewer screened the titles and abstracts of the 9975 reports identified by the electronic searches. Full-text copies of 161 potentially relevant articles were obtained, and 2 reviewers independently assessed those articles for inclusion. Adults with a physician-confirmed early localized skin infection who were treated with antibiotics of any dose or duration were included. Data Extraction and Synthesis: Two reviewers independently extracted data on study, patient, and intervention characteristics. Network meta-analyses on treatment effects and adverse outcomes were calculated with a frequentist approach using the R package netmeta. The Grading of Recommendations Assessment, Development and Evaluation guidance for NMA was used to assess the certainty of evidence. Main Outcomes and Measures: Treatment effects for response to treatment (resolution of symptoms) and treatment-related adverse events. Results: Overall, 19 studies (2532 patients) were included. The mean patient age ranged between 37 and 56 years, and the percentage of female patients ranged from 36% to 60%. The antibiotics investigated were doxycycline, cefuroxime axetil, ceftriaxone, amoxicillin, azithromycin, penicillin V, and minocycline. Pooled effect sizes from NMAs did not suggest any significant differences in treatment response by antibiotic agent (eg, amoxicillin vs doxycycline odds ratio, 1.26; 95% CI, 0.41-3.87), dose, or duration (eg, doxycycline, 200 mg/d for 3 weeks, vs doxycycline, 200 mg/d for 2 weeks, odds ratio, 1.28; 95% CI, 0.49-3.34). Treatment failures were rare at both 2 months (4%; 95% CI, 2%-5%) and 12 months (2%, 95% CI, 1%-3%) after treatment initiation. There were also no differences in the effect sizes among antibiotic agents and treatment modalities for treatment-related adverse outcomes, which were generally mild to moderate. Certainty of evidence was categorized as low and very low mostly because of imprecision, indirectness, and study limitations (high risk of bias) of the included studies. Conclusions and Relevance: This NMA suggests that neither the antibiotic agent nor treatment modality contributed to comparative effectiveness or drug-related adverse outcomes. This finding is relevant for physicians treating patients with LB and for patient decision making. PMID- 30285070 TI - Prevalence of Sexual Harassment in Academic Medicine. PMID- 30285071 TI - Association of Sexual Harassment and Sexual Assault With Midlife Women's Mental and Physical Health. AB - Importance: Sexual harassment and sexual assault are prevalent experiences among women. However, their association with health indices is less well understood. Objective: To investigate the association of history of sexual harassment and sexual assault with blood pressure, mood, anxiety, and sleep among midlife women. Design, Setting, and Participants: Nonsmoking women without cardiovascular disease were recruited from the community to undergo physical measurements (blood pressure, height, weight), medical history, and questionnaire psychosocial assessments (workplace sexual harassment, sexual assault, depression, anxiety, sleep). Exposures: Sexual harassment and sexual assault. Main Outcomes and Measures: Blood pressure, depressive symptoms, anxiety, and sleep characteristics. Results: Among the 304 nonsmoking women aged 40 to 60 years who participated in the study, all were free of clinical cardiovascular disease, and the mean (SD) age was 54.05 (3.99) years. A total of 19% reported a history of workplace sexual harassment (n = 58), and 22% reported a history of sexual assault (n = 67). Sexual harassment was related to significantly greater odds of stage 1 or 2 hypertension among women not taking antihypertensives (odds ratio [OR], 2.36; 95% CI, 1.10-5.06; P = .03) as well as clinically poor sleep (OR, 1.89; 95% CI, 1.05-3.42; P = .03), after adjusting for covariates. Sexual assault was associated with significantly greater odds of clinically elevated depressive symptoms (OR, 2.86; 95% CI, 1.42-5.77; multivariable P = .003), clinically relevant anxiety (OR, 2.26; 95% CI, 1.26-4.06; P = .006), and clinically poor sleep (OR, 2.15; 95% CI, 1.23-3.77; multivariable P = .007), after adjusting for covariates. Conclusions and Relevance: Sexual harassment and sexual assault are prevalent experiences among midlife women. Sexual harassment was associated with higher blood pressure and poorer sleep. Sexual assault was associated with poorer mental health and sleep. Efforts to improve women's health should target sexual harassment and assault prevention.

AB - Background: Breast density notification laws mandate reporting of dense breast to applicable women. The same psychological and systemic barriers that yield between race differences in mammography use will probably yield between-race differences in women's psychological and behavioral responses to breast density notifications. Purpose: We used the theory of planned behavior as a framework to examine between-race differences in the likelihood of following-up with physicians after receiving breast density notifications and to examine differences in African American and Caucasian American women's behavioral decision-making processes. Methods: A subset of 212 African American and Caucasian American women who participated in an initial and follow-up survey examining responses to breast density notifications were examined for this study. Participants reported background and demographic measures, psychological responses to receiving notifications, and planned behavior measures related to following up with physicians approximately 2 weeks after receiving their mammogram reports. Participants self-reported their behaviors 3 months later. Results: There were no between-race differences in self-reported physician communication; however, there were differences in processes that predicted behavior. For Caucasian American women, behavioral intentions, education, and income predicted behaviors. Instead of intentions, group-based medical suspicion, confusion, breast cancer worry, and breast density anxiety predicted behaviors for African American women. Conclusions: Behavioral decision-making processes for Caucasian American women were in line with well-validated theoretical predictions. For African American women, race-related medical suspicion, prior breast density awareness, and emotional responses to breast density notifications predicted behavior. The results highlight the need to focus on racially distinct psychological targets when designing interventions to support guideline concordant behavioral decisions among women who receive breast density notifications.

PMID- 30285076 TI - International Validation of the Eighth Edition of the American Joint Committee on Cancer (AJCC) TNM Staging System in Patients With Resected Pancreatic Cancer. AB - Importance: The recently released eighth edition of the American Joint Committee on Cancer TNM staging system for pancreatic cancer seeks to improve prognostic accuracy but lacks international validation. Objective: To validate the eighth edition of the American Joint Committee on Cancer TNM staging system in an international cohort of patients with resected pancreatic ductal adenocarcinoma. Design, Setting, and Participants: This international multicenter cohort study took place in 5 tertiary centers in Europe and the United States from 2000 to 2015. Patients who underwent pancreatoduodenectomy for nonmetastatic pancreatic ductal adenocarcinoma were eligible. Data analysis took place from December 2017 to April 2018. Exposures: Patients were retrospectively staged according to the seventh and eighth editions of the TNM staging system. Main Outcomes and Measures: Prognostic accuracy on survival rates, assessed by Kaplan-Meier and multivariate Cox proportional hazards analyses and concordance statistics. Results: A total of 1525 consecutive patients were included (median [IQR] age, 66 (58-72) years; 802 (52.6%) male). Distribution among stages via the seventh edition was stage IA in 41 patients (2.7%), stage IB in 42 (2.8%), stage IIA in 200 (13.1%), stage IIB in 1229 (80.6%), and stage III in 12 (0.8%); this changed with use of the eighth edition to stage IA in 118 patients (7.7%), stage IB in 144 (9.4%), stage IIA in 22 (1.4%), stage IIB in 643 (42.2%), and stage III in 598 (39.2%). With the eighth edition, 774 patients (50.8%) migrated to a different stage; 183 (12.0%) were reclassified to a lower stage and 591 (38.8%) to a higher stage. Median overall survival for the entire cohort was 24.4 months (95% CI, 23.4-26.2 months). On Kaplan-Meier analysis, 5-year survival rates changed from 38.2% for patients in stage IA, 34.7% in IB, 35.3% in IIA, 16.5% in IIB, and 0% in stage III (log-rank P < .001) via classification with the seventh edition to 39.2% for patients in stage IA, 33.9% in IB, 27.6% in IIA, 21.0% in IIB, and 10.8% in stage III (log-rank P < .001) with the eighth edition. For patients who were node negative, the T stage was not associated with prognostication of survival in either edition. In the eighth edition, the N stage was associated with 5-year survival rates of 35.6% in N0, 20.8% in N1, and 10.9% in N2 (log-rank P < .001). The C statistic improved from 0.55 (95% CI, 0.53-0.57) for the seventh edition to 0.57 (95% CI, 0.55-0.60) for the eighth edition. Conclusions and Relevance: The eighth edition of the TNM staging system demonstrated a more equal distribution among stages and a modestly increased prognostic accuracy in patients with resected pancreatic ductal adenocarcinoma compared with the seventh edition. The revised T stage remains poorly associated with survival, whereas the revised N stage is highly prognostic.

PMID- 30285079 TI - Agreement Between the Spatiotemporal Gait Parameters of Healthy Adults From the OptoGait System and a Traditional Three-Dimensional Motion Capture System. AB - While previous research has assessed the validity of the OptoGait system to the GAITRite walkway and an instrumented treadmill, no research to date has assessed this system against a traditional three-dimensional motion analysis system. Additionally, previous research has shown that the OptoGait system shows systematic bias when compared to other systems due to the configuration of the system's hardware. This study examined the agreement between the spatiotemporal gait parameters calculated from the OptoGait system and a three-dimensional motion capture (14 camera Vicon motion capture system and 2 AMTI force plates) in healthy adults. Additionally, a range of filter settings for the OptoGait were examined to determine if it was possible to eliminate any systematic bias between the OptoGait and the three-dimensional motion analysis system. Agreement between the systems was examined using 95% limits of agreement by Bland and Altman and the intraclass correlation coefficient. A repeated measure ANOVA was used to detect any systematic differences between the systems. Findings confirm the validity of the OptoGait system for the evaluation of spatiotemporal gait parameters in healthy adults. Furthermore, recommendations on filter settings which eliminate the systematic bias between the OptoGait and the three dimensional motion analysis system are provided. PMID- 30285080 TI - Prescribed Exercise With Compression vs Compression Alone in Treating Patients With Venous Leg Ulcers: A Systematic Review and Meta-analysis. AB - Importance: Exercise is recommended as an adjuvant treatment for venous leg ulceration (VLU) to improve calf muscle pump function. However, the association of exercise with VLU healing has not been properly aggregated, and the effectiveness of different exercise interventions has not been characterized. Objective: To summarize the association of different exercise interventions with VLU healing when used as an adjuvant to any form of compression. Data Sources: The Cochrane Controlled Trials Register, MEDLINE, Embase, CINAHL, PsycInfo, and SCOPUS databases were searched through October 9, 2017. Study Selection: Randomized clinical trials (RCTs) of any exercise compared with no exercise in participants with VLU were included, where compression was used as standard therapy and a healing outcome was reported. Independent title screening and full text review by 2 authors (A.J., J.S.) with appeal to a third author (J.P.) if disagreement was unresolved. Of the 519 articles screened, a total of 6 (1.2%) studies met the inclusion criteria for systematic review, including 5 for meta analysis. Data Extraction and Synthesis: Independent quality assessment for Cochrane risk of bias and data extraction by 2 authors with appeal to third author if disagreement unresolved (PRISMA). Data pooled using fixed effects model. Main Outcomes and Measures: The a priori primary outcome was any healing outcome (proportion healed, time to healing, or change in ulcer area). Secondary outcomes (adverse events, costs, and health-related quality of life) were only collected if a primary outcome was reported. Results: Six RCTs were identified and 5 (190 participants) met inclusion criteria for meta-analysis. The exercise interventions were progressive resistance exercise alone (2 RCTs, 53 participants) or combined with prescribed physical activity (2 RCTs, 102 participants), walking only (1 RCT, 35 participants), or ankle exercises (1 RCT, 40 participants). Overall, exercise was associated with increased VLU healing at 12 weeks although the effect was imprecise (additional 14 cases healed per 100 patients; 95% CI, 1-27 cases per 100; P = .04). The combination of progressive resistance exercise plus prescribed physical activity appeared to be most effective, again with imprecision (additional 27 cases healed per 100 patients; 95% CI, 9-45 cases per 100; P = .004). Conclusions and Relevance: The evidence base may now be sufficiently suggestive for clinicians to consider recommending simple progressive resistance and aerobic activity to suitable patients with VLU while further research is produced.

PMID- 30285081 TI - Evaluating Progression-Free Survival as a Surrogate Outcome for Health-Related Quality of Life in Oncology: A Systematic Review and Quantitative Analysis. AB - Importance: Progression-free survival (PFS) has become a commonly used outcome to assess the efficacy of new cancer drugs. However, it is not clear if delay in progression leads to improved quality of life with or without overall survival benefit. Objective: To evaluate the association between PFS and health-related quality of life (HRQoL) in oncology through a systematic review and quantitative analysis of published randomized clinical trials. Eligible trials addressed oral, intravenous, intraperitoneal, or intrapleural chemotherapy or biological treatments, and reported PFS or health-related quality of life. Data Sources: For this systematic review and quantitative analysis of randomized clinical trials of patients with cancer, we searched Medline, Embase, and the Cochrane Central Register of Controlled Trials from January 1, 2000, through May 4, 2016. Study Selection: Paired reviewers independently screened citations, extracted data, and assessed risk of bias of included studies. Data Extraction and Synthesis: We examined the association of difference in median PFS duration (in months) between treatment groups with difference in global, physical, and emotional HRQoL scores between groups (standardized to a range of 0-100, with higher scores representing better HRQoL) using weighted simple regressions. Main Outcome and Measure: The association between PFS duration and HRQoL. Results: Of 35 960 records screened, 52 articles reporting on 38 randomized clinical trials involving 13 979 patients across 12 cancer types using 6 different HRQoL instruments were included. The mean (SD) difference in median PFS between the intervention and the control arms was 1.91 (3.35) months. The mean (SD) differences in change of HRQoL adjusted to per-month values were -0.39 (3.59) for the global domain, 0.26 (5.56) for the physical domain, and 1.08 (3.49) for the emotional domain. The slope of the association between the difference in median PFS and the difference in change for global HRQoL (n = 30 trials) was 0.12 (95% CI, -0.27 to 0.52); for physical HRQoL (n = 20 trials) it was -0.20 (95% CI, -0.62 to 0.23); and for emotional HRQoL (n = 13 trials) it was 0.78 (95% CI, -0.05 to 1.60). Conclusions and Relevance: We failed to find a significant association between PFS and HRQoL in cancer clinical trials. These findings raise questions regarding the assumption that interventions prolonging PFS also improve HRQoL in patients with cancer. Therefore, to ensure that patients are truly obtaining important benefit from cancer therapies, clinical trial investigators should measure HRQoL directly and accurately, ensuring adequate duration and follow-up. PMID- 30285083 TI - Physical Activity Predicts Population-Level Age-Related Differences in Frontal White Matter. AB - Physical activity has positive effects on brain health and cognitive function throughout the life span. Thus far, few studies have examined the effects of physical activity on white matter microstructure and psychomotor speed within the same, population-based sample (critical if conclusions are to extend to the wider population). Here, using diffusion tensor imaging and a simple reaction time task within a relatively large population-derived sample (N = 399; 18-87 years) from the Cambridge Centre for Ageing and Neuroscience (Cam-CAN), we demonstrate that physical activity mediates the effect of age on white matter integrity, measured with fractional anisotropy. Higher self-reported daily physical activity was associated with greater preservation of white matter in several frontal tracts, including the genu of corpus callosum, uncinate fasciculus, external capsule, and anterior limb of the internal capsule. We also show that the age-related slowing is mediated by white matter integrity in the genu. Our findings contribute to a growing body of work, suggesting that a physically active lifestyle may protect against age-related structural disconnection and slowing.

AB - Lysine post-translational modifications (PTMs) play a crucial role in regulating diverse functions and biological processes of proteins. However, because of the large volumes of sequencing data generated from genome-sequencing projects, systematic identification of different types of lysine PTM substrates and PTM sites in the entire proteome remains a major challenge. In recent years, a number of computational methods for lysine PTM identification have been developed. These methods show high diversity in their core algorithms, features extracted and feature selection techniques and evaluation strategies. There is therefore an urgent need to revisit these methods and summarize their methodologies, to improve and further develop computational techniques to identify and characterize lysine PTMs from the large amounts of sequence data. With this goal in mind, we first provide a comprehensive survey on a large collection of 49 state-of-the-art approaches for lysine PTM prediction. We cover a variety of important aspects that are crucial for the development of successful predictors, including operating algorithms, sequence and structural features, feature selection, model performance evaluation and software utility. We further provide our thoughts on potential strategies to improve the model performance. Second, in order to examine the feasibility of using deep learning for lysine PTM prediction, we propose a novel computational framework, termed MUscADEL (Multiple Scalable Accurate Deep Learner for lysine PTMs), using deep, bidirectional, long short term memory recurrent neural networks for accurate and systematic mapping of eight major types of lysine PTMs in the human and mouse proteomes. Extensive benchmarking tests show that MUscADEL outperforms current methods for lysine PTM characterization, demonstrating the potential and power of deep learning techniques in protein PTM prediction. The web server of MUscADEL, together with all the data sets assembled in this study, is freely available at http://muscadel.erc.monash.edu/. We anticipate this comprehensive review and the application of deep learning will provide practical guide and useful insights into PTM prediction and inspire future bioinformatics studies in the related fields.

PMID- 30285085 TI - Instability of the mitochondrial alanyl-tRNA synthetase underlies fatal infantile onset cardiomyopathy. AB - Recessively-inherited variants in AARS2 (NM_020745.2) encoding mitochondrial alanyl-tRNA synthetase (mt-AlaRS) were first described in patients presenting with fatal infantile cardiomyopathy and multiple oxidative phosphorylation defects. To date, all described patients with AARS2-related fatal infantile cardiomyopathy are united by either a homozygous or compound heterozygous c.1774C>T (p.Arg592Trp) missense founder mutation that is absent in patients with other AARS2-related phenotypes. We describe the clinical, biochemical and molecular investigations of two unrelated boys presenting with fatal infantile cardiomyopathy, lactic acidosis and respiratory failure. Oxidative histochemistry showed cytochrome c oxidase (COX)-deficient fibres in skeletal and cardiac muscle. Biochemical studies showed markedly decreased activities of mitochondrial respiratory chain complexes I and IV with a mild decrease of complex III activity in skeletal and cardiac muscle. Using next-generation sequencing, we identified a c.1738C>T (p.Arg580Trp) AARS2 variant shared by both patients that was in trans with a loss-of-function heterozygous AARS2 variant; a c.1008dupT (p.Asp337*) nonsense variant or an intragenic deletion encompassing AARS2 exons 5-7. Interestingly, our patients did not harbour the p.Arg592Trp AARS2 founder mutation. In silico modelling of the p.Arg580Trp substitution suggested a deleterious impact on protein stability and folding. We confirmed markedly decreased mt-AlaRS protein levels in patient fibroblasts, skeletal and cardiac muscle, although mitochondrial protein synthesis defects were confined to skeletal and cardiac muscle. In vitro data showed that the p.Arg580Trp variant had a minimal effect on activation, aminoacylation or misaminoacylation activities relative to wild-type mt-AlaRS, demonstrating that instability of mt AlaRS is the biological mechanism underlying the fatal cardiomyopathy phenotype in our patients. PMID- 30285087 TI - Shedding light into the relevance of telomeres in human reproduction and male factor infertility. AB - Sperm telomere length (STL) is a promising new parameter for sperm quality analysis that may elucidate the molecular mechanisms underlying the idiopathic cases of male factor infertility, which represent almost half of all the male factor infertility cases worldwide. Telomeres consist of nucleoprotein structures present at the ends of eukaryotic chromosomes, whose protective functions maintain the genomic stability. Their role in reproduction includes an active intervention during gametogenesis, fertilization and preimplantation embryo development. In consonance, studies have shown that compromised telomere homeostasis is associated with male infertility. Since critically short telomeres have their function affected, assessing STL may be a fast and economic method for sperm quality analysis and expectantly contribute to improve the success of fertility treatments. This hypothesis is supported by several reports associating STL with seminal parameters, genome integrity and clinical outcomes. However, there are other studies in the literature that do not demonstrate these associations. Additionally, it is still not clear whether the lengthening mechanisms of telomeres occurring during early embryo development resume the inherited telomere length. Further research it is essential to clarify the suitability of STL as a biomarker for male infertility, before it could be routinely implemented in medically assisted reproduction centers. Understanding the molecular mechanisms underlying STL function and dynamics will provide us new insights into the origins of male infertility and a new useful tool as an outcome predictor for assisted reproduction. PMID- 30285088 TI - Association between dietary patterns and metabolic syndrome in the selected population of Polish adults-results of the PURE Poland Study. AB - Background: Dietary pattern (DP) analysis is a statistical method used to evaluate the comprehensive effect of the diet on health. The aim of the study was to assess the relationship between DPs derived in selected population of Lower Silesia and the prevalence of metabolic syndrome (MS) and its components. Methods: Study group consisted of 1634 individuals enrolled in the Prospective Urban and Rural Epidemiological Study Poland. Dietary intake was estimated using the data from the Food Frequency Questionnaire. DPs were identified using principal component analysis. MS prevalence was evaluated based on the criteria accepted by International Diabetes Federation, American Heart Association and National Heart, Lung and Blood Institute in 2009. Results: Three DPs were identified. The percentage of individuals with MS was lower in the upper quartile (Q) of the 'fruit & vegetables' DP in comparison with Q1 (40.4 vs. 48.9%). Inverse relationship was observed for 'Western' (Q4 vs. Q1: 50.7 vs. 40.8%) and 'traditional' DPs (51.0 vs. 38.3%). After adjusting for potential confounders, in Q4 of 'traditional' DP higher risk for central obesity was observed compared to Q1 (OR 1.52; 95% CI: 1.10-2.12). Individuals in Q3 of 'fruit & vegetables' DP had lower risk for raised blood pressure in comparison with the bottom Q (OR 0.54; 95% CI: 0.36-0.82). Conclusions: DP analysis allows to evaluate the synergistic effect of the diet on the MS prevalence. 'Fruit & vegetables' DP, in contrast to 'Western' and 'traditional' DPs, was negatively associated with the prevalence of MS and its components in the study group.

PMID- 30285090 TI - Meaningful Change Estimates for the Late-Life Function and Disability Instrument in Older Adults. AB - Background: The Late-Life Function and Disability Instrument (LLFDI) is a well validated and frequently used patient-reported outcome for older adults. The aim of this study was to estimate the minimal clinically important difference of the LLFDI-Function Component (LLFDI-FC) and its subscales among community-dwelling older adults with mobility limitations. Methods: We performed a secondary analysis of the Boston Rehabilitative Impairment Study of the Elderly, a longitudinal cohort study of older adults with mobility limitations residing in the community. The minimal clinically important difference for each LLFDI-FC scale over 1 year of follow-up was estimated using both anchor- and distribution based methods, including mean change scores on a patient-reported global rating of change in function scale, the standard error of measurement, and the minimal detectable change with 90% confidence. Results: Data from 320 older adults were used in the analysis (mean age 76 years, 69% female, mean of four chronic conditions). Meaningful change estimates for "small change" based on the global rating of change and standard error of measurement were 2, 3, 4, and 4 points for the LLFDI-FC overall function scale and basic lower-extremity, advanced lower extremity, and upper-extremity subscales, respectively. Estimates for "substantial change" based on the global rating of change and minimal detectable change with 90% confidence were 5, 6, 9, and 10 points for the overall function scale and basic lower-extremity, advanced lower-extremity, and upper-extremity subscales, respectively. Conclusion: This study provides the first minimal clinically important difference estimates for the LLFDI-FC, a widely used patient reported measure of function. These values can be used to interpret the outcomes of longitudinal investigations of functional status in similar populations of community-dwelling older adults. PMID- 30285091 TI - Specific growth conditions induce a Streptococcus pneumoniae non-mucoidal, small colony variant and determine the outcome of its co-culture with Haemophilus influenzae. AB - Haemophilus influenzae and Streptococcus pneumoniae are known aetiologic agents of chronic otitis media, frequently as a multispecies infection. In this study, we show that the outcome of H. influenzae/S. pneumoniae interactions is dependent on the nutrient source. In continuous culture containing chemically defined media with lactose, S. pneumoniae was non-viable in mono-culture, and in co-culture remained non-viable until 288 h. With glucose, S. pneumoniae became non-viable in mono-culture, but uniquely existed in 3 distinct states in co-culture: parental cells (until 24 h), a dormant state until 336 h and its re-emergence as a non mucoidal, small colony variant (SCV). The S. pneumoniae SCV was stable and whole genome sequencing showed three major single nucleotide polymorphisms in the SCV cells-cap3A (capsule biosynthesis pathway), fpg (DNA glycosylase of the DNA repair mechanism) and glutamate-5-kinase. Previously, fpg mutants have shown increased mutator rates, permitting bacterial survival against host-generated stresses. Transcriptomics showed these SCV cells up-regulated sugar transporters and toxin/antitoxin systems. An animal model revealed a reduced survival in the lungs and ear by SCV cells. This is the first study documenting the effect of carbon source and the development of a distinct S. pneumoniae cell type during H. influenzae/S. pneumoniae interactions. PMID- 30285092 TI - Strength endurance training but not intensive strength training reduces senescence-prone T-cells in peripheral blood in community-dwelling elderly women. AB - Ageing is characterized by a progressive decline in immune function known as immunosenescence (IS). While the causes of IS are likely to be multi-factorial, an age-associated accumulation of senescent T-cells and decreased naive T-cell repertoire are key contributors to the phenomenon. On the other hand, there is a growing consensus that physical exercise may improve immune response in ageing. However, the optimum training modality required to obtain beneficial adaptations in older subjects is lacking. Therefore, we aimed to investigate the effects of exercise modality on T-cell phenotypes in older women. 100 women (aged >=65 years) were randomized to either intensive strength training (80% of one repetition maximum (1RM)), strength endurance training (SET, 40% 1RM), or control (stretching exercise) for 2-3 times/week during 6 weeks. The T-cell percentages and absolute counts were determined using flow cytometry and hematology analyzer. C-reactive protein was measured using immunonephelometry. We report for the first time that 6 weeks of SET significantly decreased the basal percentage and absolute counts of senescence-prone T-cells, which was positively related to the number of training sessions performed. Conceivably, training protocols with many repetitions - at a sufficiently high external resistance - might assist the reduction of senescence-prone T-cells in older women. PMID- 30285093 TI - Alterations of sex determination pathway in the genital ridges of males with limited Y chromosome genes. AB - We previously demonstrated that in the mouse only two Y chromosome genes are required for a male to produce an offspring with the help of assisted reproduction technologies (ART): testis determinant Sry and spermatogonial proliferation factor Eif2s3y. Subsequently, we have shown that the function of these genes can be replaced by transgenic overexpression of their homologues, autosomally encoded Sox9 and X-chromosome encoded Eif2s3x. Males with Y chromosome contribution limited to two (XEif2s3yOSry), one (XEif2s3yOSox9 and XOSry, Eif2s3x) and no genes (XOSox9, Eif2s3x) produced haploid germ cells and sired offspring after ART. However, despite successful assisted reproductive outcome, they had smaller testes and displayed abnormal development of the seminiferous epithelium and testicular interstitium. Here we explored whether these testicular defects originated from altered pro-testis and pro-ovary factor signaling in genital ridges at the time of sex determination. Timed-pregnancies were generated to obtain transgenic XEif2s3yOSry, XEif2s3yOSox9, XOSry, Eif2s3x, XOSox9, Eif2s3x and wild-type XX and XY fetuses at 12.5 days post coitum. Dissected genital ridges were assessed for their morphology and anatomy, and expression of pro-testis and pro-ovary transcripts. All transgenic males displayed incomplete masculinization of gonadal shape, impaired development of testicular cords and gonadal vasculature, and decreased expression of factors promoting male pathway. Fetal gonad masculinization was more effective when sex determination was driven by the Sry transgene, in the presence of Y chromosome genes, and to a lesser extent a double dosage of X genes. The study adds to the understanding of the role of Y chromosome genes and their homologues during sex determination. PMID- 30285094 TI - Appendectomy for Therapy-Refractory Ulcerative Colitis Results in Pathological Improvement of Colonic Inflammation: Short-Term Results of the PASSION Study. AB - Background and Aims: The objective of this study was to examine the modulating effect of an appendectomy on the disease course of therapy-refractory ulcerative colitis [UC] patients, and to analyse appendiceal pathological characteristics predictive of pathological response. Methods: Patients with therapy-refractory UC, and referred for proctocolectomy, were invited to undergo laparoscopic appendectomy first. The primary end points were clinical response after 3 and 12 months. Secondary end points were endoscopic remission, failure, and pathologic response. Appendiceal specimens, and pre- and post-operative biopsies were histologically graded according to the validated Geboes score. Results: Thirty patients [53% male] with a median age of 40 (interquartile range [IQR], 33-47) underwent appendectomy, with a median preoperative total Mayo score of 9 [IQR, 8 11]. After 12 months, 9 patients [30%] had lasting clinical response, of whom 5 [17%] were in endoscopic remission. Pathological evaluation was possible in 28 patients. After a median of 13.0 weeks [range 7-51], pathological response was seen in 13 patients [46%], with a median decrease of 2 points [range 1-3]. Appendiceal inflammation was highly predictive of pathological response when compared with no inflammation or extensive ulcerations [85% vs 20%, p = 0.001]. Conclusions: Appendectomy was effective in one-third of therapy-refractory UC patients, with a substantial proportion of patients demonstrating complete endoscopic remission after 1 year. Pathological response was seen in almost 50% of patients and was related to active inflammation in the appendix, limited disease, and shorter disease duration. These early results suggest that there is a UC patient group that may benefit from appendectomy. PMID- 30285095 TI - Bacillus wiedmannii biovar thuringiensis: A Specialized Mosquitocidal Pathogen with Plasmids from Diverse Origins. AB - Bacillus cereus sensu lato also known as B. cereus group is composed of an ecologically diverse bacterial group with an increasing number of related species, some of which are medically or agriculturally important. Numerous efforts have been undertaken to allow presumptive differentiation of B. cereus group species from one another. FCC41 is a Bacillus sp. strain toxic against mosquito species like Aedes aegypti, Aedes (Ochlerotatus) albifasciatus, Culex pipiens, Culex quinquefasciatus, and Culex apicinus, some of them responsible for the transmission of vector-borne diseases. Here, we report the complete genome sequence of FCC41 strain, which consists of one circular chromosome and eight circular plasmids ranging in size from 8 to 490 kb. This strain harbors six crystal protein genes, including cry24Ca, two cry4-like and two cry52-like, a cry41-like parasporin gene and multiple virulence factors. The phylogenetic analysis of the whole-genome sequence of this strain with molecular approaches places this strain into the Bacillus wiedmannii cluster. However, according with phenotypical characteristics such as the mosquitocidal activity due to the presence of Cry proteins found in the parasporal body and cry genes encoded in plasmids of different sizes, indicate that this strain could be renamed as B. wiedmannii biovar thuringiensis strain FCC41. PMID- 30285097 TI - A Validated GC-MS Method for the Determination of Genotoxic Impurities in Divalproex Sodium Drug Substance. AB - A specific GC-MS method has been developed, optimized and validated for the determination of five genotoxic impurities namely Methyl bromide (Me.-Br), Ethyl bromide (Et.-Br), Isopropyl bromide (Ipr.-Br), n-Propyl bromide (n-Pr.-Br) and n Butyl bromide (n-But.-Br) in Divalproex sodium (DPS) drug substance. Chromatographic separation of five genotoxic impurities was achieved on DB-1 column (30 m * 0.32 mm, 3.0 MUm), consists of 100% dimethyl polysiloxane as stationary phase and passing helium carrier gas. The mass fragments (m/z) were selected for the quantification of Me.-Br (m/z 94), Et.-Br (m/z 108), Ipr.-Br (m/z 122), n-Pr.-Br (m/z 122) and n-But.-Br (m/z 136). Bromide ion (m/z 79) was the qualifier ion for the analytes [(Me.-Br), (Et.-Br), (Ipr.-Br), (n-Pr.-Br) and (n-But.-Br)]. The performance of the method was assessed by evaluating the specificity, linearity, sensitivity, precision and accuracy experiments. The established limit of detection and limit of quantification values for the genotoxic impurities were in the range of 0.005-0.019 MUg mL-1. The correlation coefficient values of the linearity experiment were in the range of 0.9947 0.9983. The average recoveries for the accuracy were in the range of 97.6-111.3%. The results proved that the method is suitable for the determination of Me.-Br, Et.-Br, Ipr.-Br, n-Pr.-Br and n-But.-Br contents in divalproex sodium. PMID- 30285096 TI - A toolkit for rapid CRISPR-SpCas9 assisted construction of hexose-transport deficient Saccharomyces cerevisiae strains. AB - Hexose transporter-deficient yeast strains are valuable testbeds for the study of sugar transport by native and heterologous transporters. In the popular Saccharomyces cerevisiae strain EBY.VW4000, deletion of 21 transporters completely abolished hexose transport. However, repeated use of the LoxP/Cre system in successive deletion rounds also resulted in major chromosomal rearrangements, gene loss and phenotypic changes. In the present study, CRISPR/SpCas9 was used to delete the 21 hexose transporters in an S. cerevisiae strain from the CEN.PK family in only three deletion rounds, using 11 unique guide RNAs. Even upon prolonged cultivation, the resulting strain IMX1812 (CRISPR Hxt0) was unable to consume glucose, while its growth rate on maltose was the same as that of a strain equipped with a full set of hexose transporters. Karyotyping and whole-genome sequencing of the CRISPR-Hxt0 strain with Illumina and Oxford Nanopore technologies did not reveal chromosomal rearrangements or other unintended mutations besides a few SNPs. This study provides a new, 'genetically unaltered' hexose transporter-deficient strain and supplies a CRISPR toolkit for removing all hexose transporter genes from most S. cerevisiae laboratory strains in only three transformation rounds. PMID- 30285098 TI - Senescent Cells Differentially Translate Senescence-Related mRNAs Via Ribosome Heterogeneity. AB - The ribosome has a lateral stalk which consists of rpLP0, rpLP1, and rpLP2. One of these proteins, rpLP2, is decreased in translating ribosome when cellular senescence is induced. Y-box binding protein-1 (YB-1) is also reduced in polysomal fraction of senescent cells. We discovered that rpLP2 depletion in the ribosome can cause the detachment of YB-1 in polysomes and that it is linked to cellular senescence. Our results also revealed that a decrement of CK2alpha or GRK2 in senescent cells induced an increment of unphosphorylated rpLP2, resulting in release of YB-1 from polysomes. This heterogeneous senescent ribosome has different translational efficiencies for some senescence-related genes. We also showed that the decrease of rpLP1/rpLP2 and YB-1 in senescent ribosomes was not specific to cell type or stress type and the same phenomenon was also observed in aged mouse livers regardless of gender. Taken together, our results suggest that the senescent ribosome complex appears to have low levels of rpLP1/rpLP2 and YB 1, resulting in altered translational efficiency for senescence-related genes. PMID- 30285099 TI - Neoatherosclerosis after drug-eluting stent implantation: a novel clinical and therapeutic challenge. AB - The recognition that obstructive disease of the epicardial coronary arteries, causing ischemic heart disease, can be treated with a percutaneous coronary intervention (PCI) has been a major discovery in cardiology in the last 40 years contributing, in particular, to the reduction of mortality associated to acute myocardial infarction (AMI). However, even in the era of drug-eluting stent (DES) implantation, a sizable proportion of patients who undergo PCI may develop late or very late post-implantation complications, that occur in the form of restenosis, neoatherosclerosis and/or in-stent thrombosis. Such complications are clinically relevant since they can cause AMI and negatively impact on the outcome. The underlying pathophysiological mechanisms are complex but related to inhibition of neointimal proliferation by DES that, on the hand, reduces the rate of in-stent restenosis, but, on the other hand, causes dysfunctional vessel healing, persistent inflammation, platelet activation and adverse immunologic responses. Multiple approaches have been developed or are under evaluation to target DES-related complications including pharmacotherapy, procedure-related imaging methods, novel stent designs and drug-delivery methods.The aim of this review is to provide an update on the latest preclinical, translational and clinical pharmacotherapeutic developments in this setting that target novel cellular mechanisms and pathways that might contribute to neoatherosclerosis. Due to the importance of secondary prevention in the reduction of DES-associated complications, this review also provides a short overview of pharmacologic agents that are established or currently being investigated in this regard.

PMID- 30285101 TI - RAB8A GTPase regulates spindle migration and Golgi apparatus distribution via ROCK-mediated actin assembly in mouse oocyte meiosis. AB - Actin filaments are widely involved in multiple cellular processes in oocyte meiosis, such as spindle migration and polar body extrusion. The actin nucleators like Arp2/3 complex and formins are the most recognized molecules for actin assembly in oocytes. In the present study, we report that the vesicle trafficking factor, RAB8A GTPase, is a new regulator critical for actin assembly in meiosis. Our results showed that RAB8A was localized at both the spindle periphery and cortex in mouse oocytes, which was similar to the localization patterns of actin filaments. RAB8A depletion caused spindle migration defects and the failure of polar body extrusion, which could have been due to decreases in both cytoplasmic and cortical actin filaments in oocytes. Based on mass spectrometry analysis, we showed that RAB8A promoted actin assembly through its modulation on the ROCK-LIMK signaling pathway. Moreover, we demonstrated that RAB8A colocalized and interacted with GM130 at the spindle periphery and that RAB8A depletion caused the disruption of GM130-docked Golgi distribution. Taken together, our data indicated that RAB8A was required for Golgi distribution, spindle migration, and polar body extrusion via ROCK-mediated actin assembly in mouse oocyte meiosis. PMID- 30285102 TI - Robust EEG-based cross-site and cross-protocol classification of states of consciousness. AB - Determining the state of consciousness in patients with disorders of consciousness is a challenging practical and theoretical problem. Recent findings suggest that multiple markers of brain activity extracted from the EEG may index the state of consciousness in the human brain. Furthermore, machine learning has been found to optimize their capacity to discriminate different states of consciousness in clinical practice. However, it is unknown how dependable these EEG markers are in the face of signal variability because of different EEG configurations, EEG protocols and subpopulations from different centres encountered in practice. In this study we analysed 327 recordings of patients with disorders of consciousness (148 unresponsive wakefulness syndrome and 179 minimally conscious state) and 66 healthy controls obtained in two independent research centres (Paris Pitie-Salpetriere and Liege). We first show that a non parametric classifier based on ensembles of decision trees provides robust out-of sample performance on unseen data with a predictive area under the curve (AUC) of ~0.77 that was only marginally affected when using alternative EEG configurations (different numbers and positions of sensors, numbers of epochs, average AUC = 0.750 +/- 0.014). In a second step, we observed that classifiers based on multiple as well as single EEG features generalize to recordings obtained from different patient cohorts, EEG protocols and different centres. However, the multivariate model always performed best with a predictive AUC of 0.73 for generalization from Paris 1 to Paris 2 datasets, and an AUC of 0.78 from Paris to Liege datasets. Using simulations, we subsequently demonstrate that multivariate pattern classification has a decisive performance advantage over univariate classification as the stability of EEG features decreases, as different EEG configurations are used for feature-extraction or as noise is added. Moreover, we show that the generalization performance from Paris to Liege remains stable even if up to 20% of the diagnostic labels are randomly flipped. Finally, consistent with recent literature, analysis of the learned decision rules of our classifier suggested that markers related to dynamic fluctuations in theta and alpha frequency bands carried independent information and were most influential. Our findings demonstrate that EEG markers of consciousness can be reliably, economically and automatically identified with machine learning in various clinical and acquisition contexts. PMID- 30285104 TI - Deep remission with vedolizumab in patients with moderately to severely active ulcerative colitis: a GEMINI 1 post hoc analysis. AB - Background and Aims: This GEMINI 1 post hoc analysis evaluated vedolizumab efficacy for inducing deep remission in patients with ulcerative colitis and correlation between vedolizumab trough concentrations and deep remission rates. Methods: Week 6 vedolizumab responders were re-randomised to placebo or vedolizumab every 8 or 4 weeks. Deep remission at Week 52 was measured using 4 different definitions (from most to least stringent): (1) Mayo Clinic endoscopic score=0, rectal bleeding score=0 and decrease or no change from baseline in stool frequency score; (2) endoscopic score <=1, rectal bleeding score=0 and stool frequency score=0; (3) endoscopic score <=1, rectal bleeding score=0, decrease or no change from baseline stool frequency score, and total score [endoscopic score + rectal bleeding score + stool frequency score] <=1; (4) endoscopic score <=1, rectal bleeding score=0 and stool frequency score <=1. Steady-state trough vedolizumab serum concentrations were evaluated. Results: At Week 6, 373 vedolizumab responders were re-randomised to maintenance placebo (n=126) or vedolizumab every 8 (n=122) or 4 (n=125) weeks. Significantly more vedolizumab patients achieved deep remission at Week 52 for the most (placebo 8.7%, every 8 weeks 27.0% [P=0.0001], every 4 weeks 28.0% [P<0.0001] and least (placebo 15.9%, every 8 weeks 43.4% [P<0.0001], every 4 weeks 43.2% [P<0.0001]) stringent definitions. Patients with higher vedolizumab trough concentration quartiles had higher deep remission rates (all definitions), versus those with the lowest quartile or who received placebo. Conclusion: Vedolizumab was associated with significantly higher deep remission rates than placebo at Week 52, regardless of deep remission definition. (NCT00783718). PMID- 30285103 TI - Color statistics of objects, and color tuning of object cortex in macaque monkey. AB - We hypothesized that the parts of scenes identified by human observers as "objects" show distinct color properties from backgrounds, and that the brain uses this information towards object recognition. To test this hypothesis, we examined the color statistics of naturally and artificially colored objects and backgrounds in a database of over 20,000 images annotated with object labels. Objects tended to be warmer colored (L-cone response > M-cone response) and more saturated compared to backgrounds. That the distinguishing chromatic property of objects was defined mostly by the L-M post-receptoral mechanism, rather than the S mechanism, is consistent with the idea that trichromatic color vision evolved in response to a selective pressure to identify objects. We also show that classifiers trained using only color information could distinguish animate versus inanimate objects, and at a performance level that was comparable to classification using shape features. Animate/inanimate is considered a fundamental superordinate category distinction, previously thought to be computed by the brain using only shape information. Our results show that color could contribute to animate/inanimate, and likely other, object-category assignments. Finally, color-tuning measured in two macaque monkeys with functional magnetic resonance imaging (fMRI), and confirmed by fMRI-guided microelectrode recording, supports the idea that responsiveness to color reflects the global functional organization of inferior temporal cortex, the brain region implicated in object vision. More strongly in IT than in V1, colors associated with objects elicited higher responses than colors less often associated with objects. PMID- 30285105 TI - A novel solution for freezing small numbers of spermatozoa using a sperm vitrification device. AB - STUDY QUESTION: Does a novel sperm vitrification device (SpermVD) provide an efficient method for freezing a small number of human spermatozoa from men suffering from non-obstructive azoospermia? SUMMARY ANSWER: The novel SpermVD is an efficient and simple carrier method for freezing a small number of spermatozoa in low-volume droplets, reducing post-thaw search time from hours to minutes, allowing a 96% recovery rate and leading to successful use of sperm for fertilization. WHAT IS KNOWN ALREADY: Previous methods for cryopreservation of small numbers of human spermatozoa (e.g. mini-straws, ICSI pipette, alginate beads, cryoloop) have been proposed as a solution for cases of severe male infertility. Many drawbacks have prevented their widespread use, including cumbersome preparation and sperm retrieval procedures, and the fact that the thawed spermatozoa are not immediately available for micromanipulation and required additional treatment which posed excess risk of harm. STUDY DESIGN, SIZE, DURATION: We conducted a feasibility experiment of the novel SpermVD and a prospective cohort study of ICSI cycles in men suffering from non-obstructive azoospermia in two outpatient fertility IVF clinics, from 2015 through 2017. PARTICIPANTS/MATERIALS, SETTING, METHODS: All patients underwent extended ejaculate search prior to the day of oocyte retrieval, and any single motile spermatozoa found was transferred to 0.8 MUl droplets of 1:1 washing medium/cryoprotectant on the SpermVD, then plunged into liquid nitrogen for cryopreservation. In patients with non-obstructive azoospermia who underwent surgical TESE, both the motile and immotile spermatozoa found underwent cryopreservation using the SpermVD. On the day of oocyte retrieval, the SpermVD was thawed, directly transfered to the ICSI plate and retrieved spermatozoa were used for the ICSI procedure. MAIN RESULTS AND THE ROLE OF CHANCE: The prospective cohort included 44 cases. We used the SpermVD to vitrify 631 spermatozoa, of which 540 (86%) were motile. The average number of frozen spermatozoa per patient was 14.3 +/- 9.3. After thawing, we retrieved 607 spermatozoa, producing a recovery rate of 96%. The average number of thawed spermatozoa was 13.8 +/- 9.2. The recovery of 180 thawed motile sperm accounted for 33% of all frozen motile spermatozoa. The fertilization rate was 59%. Of 44 oocyte retrieval procedures, 24 (55%) clinical pregnancies were achieved. The delivery rate (not including three ongoing pregnancies) was 32% and the miscarriage rate was 29%. LIMITATIONS, REASONS FOR CAUTION: Although we presented the SpermVD on 44 cases, a larger cohort would provide more information. Moreover, we cryopreserved only motile sperm from the ejaculates and not immotile sperm, thus limiting the knowledge regarding the efficacy of the VD for immotile sperm from this source. WIDER IMPLICATIONS OF THE FINDINGS: The novel SpermVD is a simple efficient carrier, optimizing the protocol for freezing a small number of spermatozoa. It may allow for the routine use of frozen spermatozoa after TESE for men suffering from non obstructive azoospermia and thus avoid repeated TESE surgeries. Furthermore, in cases of non-obstructive azoospermia, routine cryopreservation of the retrieved spermatozoa prior to the IVF cycle may avoid the risk of cycle cancelation and thus decrease the number of unnecessary oocyte retrieval procedures.

PMID- 30285106 TI - Impact of HIV-1 primary drug resistance on the efficacy of a first-line antiretroviral regimen in the blood of newly diagnosed individuals in Bamako, Mali. AB - Background: To achieve the 90-90-90 targets assigned by UNAIDS, it is crucial to monitor ART in HIV-1-infected patients, especially in resource-limited countries. Objectives: To evaluate the immunovirological response after 12 months of ART in newly HIV-1-diagnosed people in Bamako, Mali; to determine primary and acquired resistance rates to antiretroviral drugs; and to evaluate the impact of primary resistance on the efficacy of ART. Patients and methods: One hundred and nineteen HIV-1-infected people (88.2% women; median age 34 years) were enrolled between January and June 2014. HIV-1 RNA loads (Abbott RealTime HIV-1 assay) were tested in the blood before and at months 3, 6 and 12 after initiation of ART. Primary and acquired resistances to ART were evaluated by the ViroseqTM HIV-1 genotyping assay. Results: During the study, 8.4% of people died and 37% were lost to follow up. After 1 year of ART, an undetectable HIV-1 RNA viral load was found in 87.7% of cases. The overall rate of primary drug resistance mutations was 17.5% (3.2%, 15.9% and 0% for NRTIs, NNRTIs and PIs, respectively). These mutations were not associated with either higher mortality rates or larger numbers of virological failures. The acquired resistance rate was estimated at 3.1%. Conclusions: Our study showed a high primary resistance level and a huge proportion of people non adherent to the treatment programme. Reassuringly, almost 90% virological success and a low level of acquired mutations were observed in adherent people at month 12. Reinforced education, regular virological monitoring and early HIV-1 diagnosis may help to improve retention in the care system.

PMID- 30285107 TI - Genetic Diversity in the Progeny of Commercial Australian Queen Honey Bees (Hymenoptera: Apidae) Produced in Autumn and Early Spring. AB - Honey bee [Apis mellifera L. (Hymenoptera: Apidae)] queens are polyandrous, mating with an average 12 males (drones). Polyandry has been shown to confer benefits to queens and the colonies they head, including avoidance of inviable brood that can arise via sex locus homozygosity, increased resilience to pests and pathogens, and increased survival and productivity, leading to improved colony-level fitness. Queens with an effective mating frequency (ke) greater than 7 are considered adequately mated, whereas queens that fall below this threshold head colonies that have increased likelihood of failure and may be less productive for beekeepers. We determined ke in queens produced in early Spring and Autumn by five Australian commercial queen producers to determine whether the queens they produced were suitably mated. Drone populations are low at these times of year, and therefore, there is an increased risk that queens would fall below the ke > 7 threshold. We found that 33.8% of Autumn-produced queens did not meet the threshold, whereas 93.8% of Spring queens were adequately mated. The number of colonies contributing drones to the mating pool was similarly high in both seasons, suggesting that although many colonies have drones, their numbers may be decreased in Autumn and management strategies may be required to boost drone numbers at this time. Finally, queens had similar levels of homozygosity to workers, and inbreeding coefficients were very low, suggesting that inbreeding is not a problem.

AB - Mounting evidence suggested that dysfunction of long non-coding RNAs (lncRNAs) is involved in a wide variety of diseases. A knowledgebase with systematic collection and curation of lncRNA-disease associations is critically important for further examining their underlying molecular mechanisms. In 2013, we presented the first release of LncRNADisease, representing a database for collection of experimental supported lncRNA-disease associations. Here, we describe an update of the database. The new developments in LncRNADisease 2.0 include (i) an over 40-fold lncRNA-disease association enhancement compared with the previous version; (ii) providing the transcriptional regulatory relationships among lncRNA, mRNA and miRNA; (iii) providing a confidence score for each lncRNA disease association; (iv) integrating experimentally supported circular RNA disease associations. LncRNADisease 2.0 documents more than 200 000 lncRNA disease associations. We expect that this database will continue to serve as a valuable source for potential clinical application related to lncRNAs. LncRNADisease 2.0 is freely available at http://www.rnanut.net/lncrnadisease/.

PMID- 30285111 TI - Prevalence of and factors associated with under-5 mortality in South Asia. AB - Background: This study investigated the prevalence of and the factors associated with under-5 mortality across five South Asian countries. Methods: Cross sectional pooled data from 1999 through 2014 collected from the Demographic and Health Survey (DHS) in five South Asian countries (Bangladesh, India, Maldives, Nepal and Pakistan) were used. Associations of under-5 mortality with sociodemographic characteristics and maternal and child factors were studied using the Cox proportional-hazard method. The estimates were presented as hazard ratios (HR) and their 95% CIs. Kaplan-Meier survival curves were used to describe time-to-event of under-5 survival patterns. Results: Overall, 15-year prevalence of under-5 mortality in South Asian countries was 10%, with Nepal having the highest prevalence (11.1%) and the Maldives the lowest (5%). In a multivariable model in pooled data, older age of mother (HR 0.70, 95% CI 0.68-0.72), being employed (HR 1.09, 95% CI 1.07-1.12), having a higher level of education (HR 0.36, 95%, CI 0.32-0.40) and having a husband with higher level of education (HR 0.74, 95% CI 0.70-0.78) were significantly associated with under-5 mortality. Factors associated with under-5 mortality were mostly common across countries. Conclusion: The prevalence of under-5 mortality is still high in South Asia. Most of the studied sociodemographic factors were associated with under-5 mortality and were common across South Asian countries. PMID- 30285112 TI - How lymphatic filariasis was eliminated from an urban poor setting in Santo Domingo, Dominican Republic. AB - Background: While progress has been made in the elimination of lymphatic filariasis, challenges that call for innovative approaches remain. Program challenges are increasingly observed in 'hard-to-reach' populations: urban dwellers, migrant populations, those living in insecurity, children who are out of school and areas where infrastructure is weak and education levels are low. 'Business-as-usual' approaches are unlikely to work. Tailored solutions are needed if elimination goals are to be reached. This article focuses on mass drug administrations (MDAs) in urban settings. Methods: We selected the urban poor area of Santo Domingo, Dominican Republic. With three rounds of MDA and with good coverage, elimination was achieved. We wanted to understand contributing factors to achieving good coverage. A qualitative study analyzed context, barriers and facilitators using a predefined framework based on review of the literature. Results: Results show that barriers commonly reported in urban settings were present (population density, lack of organization in household layout, population mobility, violence, shortage of human resources and challenges in monitoring treatment coverage). Tactics used included strong visibility in the community leading to high levels of awareness, the use of laminated photo sheets during house-to-house visits and a 1:4 supervision strategy. The importance of working through community leadership structures and building relationships with the community was evident. Discussion: The approach developed here has applications for large-scale treatment programs for lymphatic filariasis and other diseases in urban settings. PMID- 30285113 TI - Diagnostic ability and inappropriate antibiotic prescriptions: a quasi experimental study of primary care providers in rural China. AB - Background: China has one of the highest rates of antibiotic resistance. Existing studies document high rates of antibiotic prescription by primary care providers but there is little direct evidence on clinically inappropriate use of antibiotics or the drivers of antibiotic prescription. Methods: To assess clinically inappropriate antibiotic prescriptions among rural primary care providers, we employed unannounced standardized patients (SPs) who presented three fixed disease cases, none of which indicated antibiotics. We compared antibiotic prescriptions of the same providers in interactions with SPs and matching vignettes assessing knowledge of diagnosis and treatment to assess overprescription attributable to deficits in diagnostic knowledge, therapeutic knowledge and factors that lead providers to deviate from their knowledge of best practice. Results: Overall, antibiotics were inappropriately prescribed in 221/526 (42%) SP cases. Compared with SP interactions, prescription rates were 29% lower in matching clinical vignettes (42% versus 30%, P < 0.0001). Compared with vignettes assessing diagnostic and therapeutic knowledge jointly, rates were 67% lower in vignettes with the diagnosis revealed (30% versus 10%, P < 0.0001). Antibiotic prescription in vignettes was inversely related to measures of diagnostic process quality (completion of checklists). Conclusions: Clinically inappropriate antibiotic prescription is common among primary care providers in rural China. While a large proportion of overprescription may be due to factors such as financial incentives tied to drug sales and perceived patient demand, our findings suggest that deficits in diagnostic knowledge are a major driver of unnecessary antibiotic prescriptions. Interventions to improve diagnostic capacity among providers in rural China are needed. PMID- 30285114 TI - Surviving in the absence of flowers: do nectar yeasts rely on overwintering bumblebee queens to complete their annual life cycle? AB - Floral nectar represents an ephemeral habitat that is restricted in time and space to zoophilous flowering vegetation. To survive in these habitats, nectar inhabiting microorganisms rely on animal vectors to disperse from one flower to the next. However, it remains unclear how nectar yeasts persist when flowers and nectar cease to be present. Here, we tested the hypothesis that hibernating bumblebee queens function as a reservoir for nectar yeasts in the absence of plants or pollinators during winter. Our results show that the nectar yeast, Metschnikowia reukaufii, was present in the gastrointestinal tract of wild bumblebee queens that emerged from hibernation and that it could persist inside the gut of hibernating queens under experimental conditions. However, no evidence for such persistence was found in the case of the second most frequent nectar yeast, M. gruessii. Furthermore, a phylloplane yeast that occasionally inhabits nectar, Rhodotorula mucilaginosa, was able to colonize the gut under experimental conditions. Two bumblebee-associated yeasts, Candida bombi and C. bombiphila, were successfully passed down generations after administration in commercial lab reared bumblebees. Overall, these results demonstrate that bumblebees could act as a reservoir for nectar yeasts during winter when floral nectar is absent.

PMID- 30285115 TI - Paradoxical GH increase during OGTT is associated to first-generation somatostatin analogs responsiveness in acromegaly. AB - CONTEXT: The oral glucose tolerance test (OGTT) is considered the most useful method for diagnosing active acromegaly and for patient follow-up after neurosurgery. Despite its widespread use, only a few small studies have so far focused on patients' clinical features associated with different GH responsiveness to OGTT. OBJECTIVE: We aimed to investigate the association between glucose-induced GH response and endocrine profiles, clinical manifestations, and response to therapy in a large cohort of patients with acromegaly. PATIENTS: Based on GH response to the OGTT, patients were grouped as paradoxical (GH-Par) or non-paradoxical (GH-NPar), and their clinical and pathological features were compared in terms of pituitary tumor size, invasiveness, biochemical profiles, and response to therapy. RESULTS: The study concerned 496 acromegalic patients. At diagnosis, GH-Par patients (n=184) were older than GH-NPar patients (n=312) (mean 44.1+/-13.7 years vs 40.5+/-12.7, p<0.01), and had smaller tumors (0.82 vs 1.57 cm3, p<0.01), that less frequently invaded the cavernous sinus (15% vs 27%, p<0.01). The GH-Par group also had a higher basal GH per volume ratio (14.3 vs 10.5 MUg/L?cm3, p<0.05) and a lower incidence of hyperprolactinemia (17% vs 30%, p<0.01) than the GH-NPar patients. Importantly, the GH-Par group had a higher rate of remission in response to somatostatin analogs (52% vs 26%, p<0.01), and a more marked drop in IGF-1 and GH after six months of therapy. CONCLUSIONS: Our data strongly suggest that serum GH responsiveness to oral glucose challenge reflects some significant biological features of pituitary tumors and the OGTT may have some prognostic value.

AB - Background: The prevalence and risk factors for diabetes in Ghana vary from location to location, yet no study has been conducted to quantitatively synthesize the available studies. Methods: The authors conducted a comprehensive literature search in Medline (PubMed), Embase, Cinahl, Web of Science, Scopus, African journals and grey literature. Two reviewers screened the articles for relevance, identified and selected studies based on inclusion and exclusion criteria. Methodological quality was independently assessed, using two validated assessment-of-bias tools. We explored study heterogeneity and performed a publication bias check. Results: This search yielded a total of 624 articles, of which 17 studies were finally selected for the qualitative review and 12 studies included in the meta-analysis. The overall prevalence of diabetes mellitus among adult Ghanaians was high at 6.46% (95% CI: 4.66-8.26%) based on the inverse variance random-effects model. Significant risk factors associated with diabetes were a family history of diabetes (OR: 3.46, 95% CI: 2.50-4.78), physical inactivity (OR: 3.06, 95% CI: 1.66-5.64) and age >=40 years (OR: 2.36, 95% CI: 1.77-3.16). Conclusion: Studies with high methodological quality provided sufficient evidence about diabetes prevalence among adults and the associated significant risk factors in Ghana. PMID- 30285119 TI - Persistent Effects of Antenatal Synthetic Glucocorticoids on Endocrine Stress Reactivity from Childhood to Adolescence. AB - Context: Antenatal synthetic glucocorticoid (sGC) therapy has been identified as potent programming factor of the hypothalamic-pituitary-adrenal (HPA) axis. We previously observed significantly increased cortisol stress responses in 6-11-yr old, term-born children exposed to antenatal sGC treatment compared to controls. These findings clearly call for longitudinal follow-up studies to evaluate long term effects of antenatal sGCs, given that adolescence is marked by a significant shift of HPA-axis functioning. Objective: This study aimed to longitudinally investigate the stability of antenatal sGCs-related effects on cortisol stress reactivity from childhood to adolescence. Design, Setting, and Participants: To evaluate long-term trajectories of antenatal sGC therapy, we have longitudinally followed a subsample (n=44) of our children's cohort into late adolescence (14-18 yr-old) for a second assessment of cortisol stress reactivity. To this end, 22 adolescents with antenatal sGC exposure (dexamethasone or betamethasone) and 22 untreated controls underwent a standardized laboratory stressor (Trier Social Stress Test). Results: While we observed a general increase in HPA-axis reactivity from childhood to adolescence (P<0.05), participants treated with antenatal sGCs showed significantly higher cortisol levels in response to the TSST compared to controls during both developmental stages (P<0.05). Furthermore, we observed a moderating effect of sGC treatment on rank-order stability of cortisol stress reactivity from childhood to adolescence (P<0.05) with a trend (p=0.07) for higher rank-order stability in sGC exposed individuals (r=0.37) compared to controls (r=-0.20). Conclusion: These findings suggest that antenatal sGC therapy yields long-term changes of HPA-axis reactivity that persist into late adolescence and may confer increased vulnerability for developing stress related disorders.

PMID- 30285122 TI - The prevalence of midline prostatic cysts and the relationship between cyst size and semen parameters among infertile and fertile men. AB - STUDY QUESTION: When is the investigation and treatment of midline prostatic cysts (MPC) of clinical value in the work-up of males of infertile couples? SUMMARY ANSWER: With a prevalence of 10.2% in infertile men, MPC should be investigated according to a seminal algorithm detecting a MPC volume >0.117 ml, which may impair semen parameters, and could be treated to improve sperm count and achieve natural pregnancy. WHAT IS KNOWN ALREADY: MPC are frequent and are considered a correctable cause of male infertility. However, they have been poorly investigated in an infertility setting. In addition, no study has investigated clinical and ultrasound (US) characteristics of men with MPC. STUDY DESIGN, SIZE, DURATION: A cross-sectional analysis was carried out of 693 consecutive subjects consulting for couple infertility from September 2012 to March 2017. As a control group, 103 age-matched healthy, fertile men were studied. Furthermore, a longitudinal evaluation of 11 infertile men undergoing trans-rectal ultrasonically-guided cyst aspiration (TRUCA), semen analyses 1 and 3 months after TRUCA and a follow-up 1 year after TRUCA to assess natural pregnancy were performed. PARTICIPANTS/MATERIALS, SETTING, METHODS: All subjects underwent, in our outpatient clinic, clinical, hormonal, scrotal and transrectal US evaluation and semen analysis within the same day. Of 693 males of infertile couples, 648 (37.1 +/- 7.9 years, mean+SD) without genetic abnormalities were studied, along with 103 fertile men (36.6 +/- 5.0 years). Eleven infertile men underwent TRUCA and were followed-up as reported above. MAIN RESULTS AND THE ROLE OF CHANCE: A MPC was present in 66/648 (10.2%) males of infertile couples and in 6/103 (5.8%) fertile men. MPC occurrence and volume were higher in patients with severe oligo- or azoospermia than in fertile men (all P < 0.05). Infertile men with a MPC showed a lower seminal volume and sperm count and a higher prevalence of azoospermia than the rest of the infertile sample or fertile men, and a higher frequency of US signs suggestive of ejaculatory duct obstruction. MPC volume was negatively associated with total sperm count (r = -0.452, P < 0.0001). In fertile men, the highest MPC volume was 0.117 ml, suggesting it as a biological threshold not compromising semen quality. In infertile men, using receiver operating characteristic curve analyses, a MPC volume >0.117 ml identified subjects with severe oligo- or azoospermia with an overall accuracy of ~75% (both P < 0.005). Eleven men with infertility, semen abnormalities and large MPC (>0.250 ml) underwent TRUCA, which led to sperm count improvement in all patients 1 month after surgery. Three months after TRUCA a lower sperm count and a higher MPC volume than 2 months before were observed (P < 0.005 and P < 0.05, respectively), although improved when compared to baseline. After TRUCA a natural pregnancy occurred in four couples. Finally, we propose an algorithm, based on semen parameters, useful in identifying a MPC in males of infertile couples. LIMITATIONS, REASONS FOR CAUTION: Although in line with the sample size of previous studies (n = 7-20), the number of infertile men with MPC evaluated longitudinally after treatment is limited (n = 11). In addition, although a MPC volume >0.117 ml can negatively affect the sperm count, only MPC > 0.250 ml have been treated in this study. WIDER IMPLICATIONS OF THE FINDINGS: First, the algorithm proposed is easy to use and useful for selecting patients who can benefit from a prostate US in the infertility work-up. Second, a MPC volume <=0.117 ml may not impair semen quality, while a larger volume can lead to severe oligo- or azoospermia and could be treated. Third, TRUCA is effective, and simpler and less invasive than other surgical techniques for MPC treatment. Finally, since the MPC can increase in size and sperm count decrease over time after TRUCA, semen cryopreservation should be considered 1 month after TRUCA.

PMID- 30285121 TI - Aquaporin-3 mediates ovarian steroid hormone-induced motility of endometrial epithelial cells. AB - STUDY QUESTION: How does aquaporin-3 (AQP3) affect endometrial receptivity? SUMMARY ANSWER: AQP3, which is regulated by the combination and estrogen (E2) and progesterone (P4), induces epithelial-mesenchymal transition (EMT) of endometrial epithelial cells. WHAT IS KNOWN ALREADY: Embryo implantation is an extremely complex process, and endometrial receptivity is essential for successful embryo implantation. Estrogen and progesterone regulate endometrial receptivity. AQP3, which is regulated by estrogen (E2), increases cell migration and invasion ability by regulating the expression of EMT-related factors and influencing the reorganization of the actin cytoskeleton. STUDY DESIGN, SIZE, DURATION: This study investigated the pathophysiological significance of AQP3 in human endometrial function during different phases of the menstrual cycle. PARTICIPANTS/MATERIALS, SETTING, METHODS: AQP3 expression levels during different phases of the menstrual cycle were measured using immunohistochemical assays. In cells of different receptivity (high-receptive RL95-2 cells and low-receptive HEC 1A cells), the expression of AQP3 was measured using western blotting, qRT-PCR and immunofluorescence assays. Activities of AQP3, and its regulation by E2 and P4, were studied through in-vitro experiments using RL95-2 cells. MAIN RESULTS AND THE ROLE OF CHANCE: AQP3 expression in the mid- and late-secretory phases of the human endometrium is significantly higher than in other phases. Since AQP3 expression levels were higher in RL95-2 cells than in HEC-1A cells, mechanisms of AQP3 regulation by E2 and P4 were studied using RL95-2 cells. We provided the first report that P4 up-regulates AQP3 by directly targeting the promoter of the AQP3 gene. The up-regulation of AQP3 expression by a combination of E2 and P4 is significantly higher than that caused by either E2 or P4 alone. Together E2 and P4 promote RL95-2 cell migration and invasion by inducing EMT through AQP3. We also found that AQP3 co-localizes with ezrin and affects the formation of filopodia and lamellipodia during the E2 and P4-induced EMT process but has no effect on the expression of ezrin and F-actin. LARGE SCALE DATA: N/A. LIMITATIONS, REASONS FOR CAUTION: It is still unclear whether AQP3 is a main regulator of endometrial receptivity or one of several factors influencing the process. WIDER IMPLICATIONS OF THE FINDINGS: Further investigation on AQP3 may contribute to a greater understanding of endometrial receptivity.

AB - Objective: The role of selective beta2-adrenergic stimulation in regulation of leg glucose uptake and free fatty acid (FFA) balance is inadequately explored in humans. The objective of this study was to investigate beta2-adrenergic effects on net leg glucose uptake and clearance, and FFA balance at rest and during exercise. Design: The study was a randomized, placebo-controlled crossover trial, where 10 healthy men received either infusion of beta2-agonist terbutaline (0.2 0.4 mg) or placebo. Net leg glucose uptake and clearance, and FFA balance were determined at rest and during 8 min of knee-extensor exercise using Fick's principle. Vastus lateralis muscle biopsies were collected at rest and at cessation of exercise. The primary outcome measure was net leg glucose uptake. Results: At rest, net leg glucose uptake and clearance were 0.35 (+/-0.16) mmol*min-1 and 41 (+/-17) mL*min-1 (mean+/-95%CI) higher (p<0.001) for terbutaline than placebo, corresponding to increases of 84 and 70%. During exercise, no treatment differences were observed in net leg glucose uptake, whereas clearance was 101 (+/-86) mL*min-1 lower (p<0.05) for terbutaline than placebo. At rest, terbutaline induced a net leg FFA release of 21 (+/-14) umol*min-1, being different from placebo (p=0.04). During exercise, net leg FFA uptake was not different between the treatments. Conclusions: These observations indicate that beta2-agonist alters net leg glucose uptake and clearance, as well as FFA balance in humans, which is associated with myocellular beta2-adrenergic and insulin-dependent signaling. Furthermore, the study shows that exercise confounds the beta2-adrenergic effect on net leg glucose uptake and FFA balance. PMID- 30285126 TI - Explaining mechanisms that influence smoke-free implementation at the local level: A realist review of smoking bans. AB - Introduction: While studies have been undertaken to understand the adoption of outdoor and indoor smoking bans, not much is known about why implementation of smoke-free (SF) environments differs at local levels. As most European countries remain at the level of indoor bans, we aim to translate existing evidence into practical recommendations on how to improve SF (outdoor) implementation within European municipalities. Methods: We applied six methodological steps of a realist review consistent with the RAMESES publication standards for realist syntheses. Literature search was conducted in PubMed/MEDLINE and Web of Science. In total, 3,829 references were screened, of which 43 were synthesized. Studies dating from 2004-2015 with rigor evidence of SF implementation at the local level were selected. Implementation outcomes were SF enforcement, monitoring, non smoking compliance, and public support in cities. Results: The explanatory realist framework links 4 innovation stages with 3 context-mechanism-outcome configurations (CMOs). We identified "triggering trust", "increasing priorities", and "limiting opposing interests" as underlying mechanisms, when (1) establishing, (2) developing, (3) contesting, and (4) implementing local smoking bans. The CMOs support practical recommendations, such as (a) providing authorities with local data when establishing and developing bans, (b) developing long-term strategies and implementing state-funded SF programs to prioritize sustained enforcement, and (c) limiting opposing interests through the use of the child protection frame. Conclusions: This is the first realist review on the implementation of SF enviroments at the local level. The process-oriented theory explains how and why CMOs determine SF development in cities and municipalities from planning until implementation. Implications: In 2015, only 16% of the world's population lived under the jurisdiction of comprehensive smoke-free (SF) laws. The findings of this realist review are useful to implement WHO goals of the Framework Convention on Tobacco Control (FCTC) and specifically SF environments at more local levels and to adjust them to specific contextual circumstances. This paper unpacks three mechanisms that could be triggered by SF strategies developed at local levels and that can result in improved policy implementation. Such evidence is needed to enhance SF strategies at the level of cities and municipalities and to achieve WHO Healthy Cities Network objectives. PMID- 30285127 TI - Ultrasound evaluation in follow-up of urate-lowering therapy in gout: the USEFUL study. AB - Objectives: We aimed to determine the ability of ultrasonography (US) to show disappearance of urate deposits in gouty patients requiring urate-lowering therapy (ULT). Methods: We performed a 6-month multicentre prospective study including patients with: proven gout; presence of US features of gout (tophus and/or double contour sign) at the knee and/or first metatarsophalangeal joints; and no current ULT. US evaluations were performed at baseline and at months 3 and 6 (M3, M6) after starting ULT. Outcomes were: the change in US features of gout at M6 according to final (M6) serum urate (SU) level (high, > 360 MUmol/l, i.e. > 6 mg/dl; low, 300-360 MUmol/l, i.e. 5-6 mg/dl; very low, < 300 MUmol/l, i.e. < 5 mg/dl); and correlation between changed US features and final SU level. Results: We included 79 gouty patients (mean +/- s.d., age 61.8 (14) years, 91% males, disease duration 6.3 (6.1) years). Baseline SU level was 530 +/- 97 umol/l (i.e. 8.9 mg/dl +/- 1.6mg/dl). At least one US tophus and double contour sign was observed in 74 (94%) and 68 (86%) patients, respectively. Among the 67 completers at M6, 18 and 39 achieved a very low and low SU level, respectively. We found a significant decrease in US features of gout among patients with the lowest SU level (P < 0.001). Final M6 SU level was positively correlated with decreased size of tophus (r = 0.54 [95% CI: 0.34, 0.70], P < 0.0001), and inversely correlated with proportion of double contour sign disappearance (r=-0.59 [-0.74, 0.40]). Conclusion: US can show decreased urate deposition after ULT, which is correlated with decreased SU level. The responsiveness of US in gout is demonstrated and can be useful for gout follow-up and adherence to ULT. PMID- 30285128 TI - Enhancing nutrient utilization of broiler chickens through supplemental enzymes. AB - The objective was to determine effects of adding phytase, amylase, and a cocktail of non-starch polysaccharide-degrading enzymes (NSPase) individually or in combinations to corn-soybean meal-based diet for broilers on apparent ileal digestibility (AID) of nutrients and dietary AMEn value. Four hundred and eighty male broiler chicks were divided into 80 groups and fed 8 diets in a completely randomized design (10 groups/diet) from day 15 to 21 of age. The diets were basal diet unsupplemented or supplemented with phytase (1,500 FTU/kg; Ronozyme HiPhos), amylase (80 KNU/kg, Ronozyme HiStarch), and NSPase (75 g/metric ton, Ronozyme Multigrain) individually or in all possible combinations. The basal diet contained the phytase at 1,000 FTU/kg, and was formulated to meet the NRC (1994) recommended nutrient requirements for broiler chickens except for ME, Ca, and non phytate P, which were reduced by 150 kcal/kg, 0.18%, and 0.15%, respectively. Addition of phytase to the basal diet increased (P < 0.05) AID of P from 40.4 to 59.3%. Addition of amylase, NSPase or a combination of amylase and NSPase to the phytase-supplemented basal diet further increased (P < 0.05) AID of P to 63.4, 69.9, and 67.3%, respectively. Addition of phytase, amylase or a combination of amylase and NSPase to the basal diet did not affect dietary AMEn value. However, addition of NSPase alone or a combination of phytase and amylase or of phytase and NSPase to the basal diet improved (P < 0.05) dietary AMEn value from 3,203 to 3,339, 3,309 or 3,289 kcal/kg, respectively. In conclusion, it is more beneficial (with regard to AID of P and dietary AMEn) to add amylase and NSPase to phytase supplemented diets for broilers. Because the basal diet contained phytase at 1,000 FTU/kg, the increase in AID of P due to supplemental phytase (1,500 FTU/kg) indicates that supplemental phytase at 2,500 FTU/kg is more beneficial with regard to improving AID of P than supplemental phytase at 1,000 FTU/kg.

PMID- 30285145 TI - The Influence of Health Numeracy and Health Warning Label Type on Smoking Myths and Quit-Related Reactions. AB - Introduction: Health numeracy helps individuals understand risk information, but limited data exist concerning numeracy's role in reactions to varying types of health warning labels (HWLs) for cigarettes. Methods: A nationally representative online panel of adult current smokers received two exposures (1 week apart) to nine HWLs with either text-only or pictorial images with identical mandated text. Following the second exposure, participants (n = 594) rated their beliefs in smoking myths (eg, health-promoting behaviors can undo the risks of smoking) and how much the warnings made them want to quit smoking. Generalized estimating equation regression examined the relation of objective health numeracy and its interaction with HWL type to smoking-myth beliefs and quit-related reactions. Results: Health numeracy was not significantly associated with smoking-myth beliefs; the interaction with HWL type was also nonsignificant. Adult smokers with lower health numeracy had higher quit-related reactions than those with higher numeracy following exposure to HWLs. The type of HWL significantly modified numeracy's associations with quit-related reactions; no significant association existed between text-only HWLs and quit-related reactions, whereas among those who viewed the pictorial warnings, lower numeracy was associated with greater quit-related reactions (beta = -.23; p < .001). Conclusions: Lower as compared to higher health numeracy was significantly associated with higher quit related reactions to HWLs and especially with pictorial HWLs. Health numeracy and HWL type were not associated with the endorsement of smoking myths. The role of health numeracy in effectively communicating risks to smokers warrants thoughtful consideration in the development of tobacco HWLs. Implications: Health numeracy plays an important role in an individual's ability to understand and respond to health risks. Smokers with lower health numeracy had greater quit-related reactions to pictorial health warnings than those who viewed text-only warning labels. Development and testing of health warning labels should consider health numeracy to most effectively communicate risk to US smokers. PMID- 30285146 TI - Leptin as a breast milk component for the prevention of obesity. AB - Leptin ingested as a component of breast milk is increasingly recognized to play a role in the postnatal programming of a healthy phenotype in adulthood. Besides its primary function in controlling body weight, leptin may be an essential nutrient required during lactation to ensure that the system controlling fat accumulation and body composition is well organized from the early stages of development. This review delves into the following topics: (1) the imprinted protective function of adequate leptin intake during lactation in future metabolic health; (2) the consequences of a lack of leptin intake or of alterations in leptin levels; and (3) the mechanisms described for the effects of leptin on postnatal programming. Furthermore, it highlights the importance of breastfeeding and the need to establish optimal or reference intake values for leptin during lactation to design patterns of personalized nutrition from early childhood. PMID- 30285147 TI - Infant nocturnal wakefulness: a longitudinal study comparing three sleep assessment methods. AB - Study Objectives: To examine the convergence between actigraphy, sleep diaries, and the Brief Infant Sleep Questionnaire (BISQ) in the assessment of infant nocturnal wakefulness (i.e. minutes awake after sleep onset [WASO] and number of night-wakings [NW]) in the context of a longitudinal study. Methods: The sample included 226 families, who were recruited during pregnancy. Data were collected at 3, 6, 12, and 18 months postpartum. Infants' sleep was monitored at home for five nights using actigraphy, sleep diaries, and the BISQ. Outcome measures included WASO and NW, as well as sleep latency, sleep duration, and sleep onset. Results: Trajectory analyses demonstrated that all three methods showed declines in NW and WASO from 3 to 18 months. Statistically significant correlations were found between the three methods at all assessment points for all sleep variables. However, agreement rates (using Krippendorff's alpha and Bland-Altman analyses) between actigraphy and parental reports were poor. For NW, agreement between actigraphy and parental reports at 18 months was lower than that at 3 and 6 months. Diaries and BISQ showed satisfactory agreement for sleep latency. Conclusions: Although the three methods' measures of infant nocturnal wakefulness are significantly correlated during infancy, absolute agreement between these methods is poor overall. The growing disagreement between actigraphy and parental reports (in NW) across development probably suggests that parents become less aware of infants' awakenings, due to the increasing ability of infants to self soothe. Using both objective and subjective assessment methods seems especially important after the age of 6 months. PMID- 30285148 TI - Effect of embryonic thermal manipulation on heat shock protein 70 (HSP70) expression and subsequent immune response to post-hatch lipopolysaccharide challenge in Pekin ducklings. AB - During the course of multi-stage incubation, small locational differences in incubation temperature within a machine are not uncommon and so the goal of this study was to study the immune response of ducklings exposed to thermal manipulation during incubation. Commercial Pekin duck eggs (n = 200) were distributed among four treatment: SS-Control (37.5 degrees C from embryonic day [ED] 1 to 25); SS-LPS (37.5 degrees C from ED1 to 25 + LPS at D0 [hatch]); HH-LPS (38 degrees C from ED1 to 25+ LPS at D0); SH-LPS (37.5 degrees C from ED1 to 10 and 38 degrees C from ED 11 to 25 + LPS at D0). At D0, ducklings received a lipopolysaccharide (LPS) injection. At D1 and D5, the HH-LPS treatment significantly reduced body weight (P <= 0.05). At D1 and D3 post-LPS injection, the SH-LPS and HH-LPS treatments significantly reduced splenic and bursal heat shock protein 70 (HSP70), mRNA abundance, and macrophage nitric oxide production compared with the SS-LPS treatment (P <= 0.05). At D1, the HH-LPS and SH-LPS treatments had increased splenic IL-10 mRNA and lower MHC I mRNA compared with the SS-LPS treatment (P <= 0.05). At D1, the HH-LPS treatment increased splenic IL-6 mRNA and bursal IFNgamma mRNA transcription while the SH-LPS treatment reduced splenic IL-6 mRNA compared with the SS-LPS treatment (P <= 0.05). The HH LPS treatment reduced thymocyte proliferation efficiency, while at D1, D3, and D5, the SH-LPS treatment increased thymocyte proliferation efficiency compared with the SS-LPS treatment (P <= 0.05). Ducklings in the HH-LPS treatment had a higher splenic CD8+/CD4+ ratio compared to the SS-LPS treatment at D3 post-LPS injection (P <= 0.05). In summary, the HH-LPS treatment compromised immunocompetence via decreased NO production and thymocyte proliferation efficiency, while the SH-LPS treatment increased body weight and thymocyte proliferation and reduced IL-6 mRNA abundance. This suggests that an embryonic temperature stress during the latter half of incubation may prime the immune system which may be beneficial during secondary post-hatch inflammatory challenges. PMID- 30285149 TI - Evolution of intestinal microbiota and body compartments during spontaneous hyperphagia in the Greylag goose. AB - The aim of this work was to study the effects of spontaneous hyperphagia on the evolution of intestinal microbiota and body compartments in old goose. From October 25th to November 26th, 5-yr-old breeding Greylag Landaise geese (106 males and 106 females) were fed with grass during 1 mo (G period). From November 26th (0 d) the birds had ad libitum access to pellets (AMEn: 10.5 MJ/kg, CP: 18.9 g/kg; spontaneous fattening (SF) period). Some birds were killed at -31 d (n = 24; 50/50 sex ratio), 0 d (n = 48), 14 (n = 46), 22 d (n = 46), and 70 d (n = 48) after the start of G period to measure body traits. For microbial analysis, 10 of the samples per sex at 0 d, 14 d, and 70 d were selected to be representative of body traits. Between 0 and 22 d, liver weight increased from 98 g to 194 g in males and from 89 g to 199 g in females (P < 0.001). Liver weight decreased between 22 and 70 d from 194 to 174 g in males and from 199 to 163 g in females (P < 0.001). Irrespective of the diet (G or SF period) and the sex of the bird, the two major phyla were Proteobacteria (49%) and Firmicutes (48%). Bacteroidetes represented around 3.0% of the sequences. At order level, Firmicutes were dominated by Clostridiales (33% of total sequences) and Lactobacillales (13% of total sequences) and Proteobacteria were dominated by Campylobacteriales (34% of total sequences). Finally, Bacteroidetes were dominated by Bacteroidales. SF and sex did not change the microbial diversity but sparse partial least squares discriminant analysis allowed us to highlight discriminant operational taxonomic unit between experimental groups. In conclusion, our result showed that changes in the body compartments of old geese during spontaneous hyperphagia depend on the sex of the birds, but not so much in gut microbial composition. Further investigations are necessary to understand the functional microbiota and highlight the role of gut microbiota in hepatic steatosis induced with hyperphagia in geese. PMID- 30285151 TI - Feasibility of a smartphone-based tobacco treatment for HIV-infected smokers. AB - Background: Cigarette smoking is common among persons living with HIV (PLWH) in the US, it is the leading cause of mortality in this group, and efforts to promote cessation have been largely unsuccessful. Methods: From 2015-2017, we performed a randomized controlled trial of Positively Smoke Free- Mobile (PSF-M) vs. standard care. PSF-M is a mobile website that offers a 42-day text message based quit-smoking program with smartphone features including quit-day selection/calendar, educational/motivational videos, and HELP button for cravings. Results: One hundred individuals enrolled, 48 were randomized to PSF-M (mean age=45, 54% male, 81% Black, 31% Latino) and 52 to the standard care condition. All participants were offered a three month supply of nicotine patches. Participants randomized to the mobile intervention visited the PSF-M homepage a mean of 83 times, viewed 5.6/8 videos, logged in on 13 of 42 possible days, and received 131 texts. 77% tapped HELP for cravings, and craving response options were utilized by the following proportions: phone-a-friend-58%, play-a game-29%, play-a-song-4%. Older age and non-Black race were both associated with higher levels of engagement with the site. 61% rated PSF-M very/extremely helpful, and 98% would recommend PSF-M to PLWH family/friends. Abstinence at 3 months, quit attempts, and daily cigarette intake all favored PSF-M over standard care, but did not achieve statistical significance in our pilot sample. Conclusions: Smartphone-based tobacco treatment for PLWH was feasible and achieved moderate-high rates of engagement and satisfaction in a middle-aged, ethnic/racial minority group in the poorest urban community in the US. Implications: Cigarette smoking has emerged as the leading killer of persons living with HIV (PLWH). Behavioral interventions have achieved only limited success in promoting cessation in this population. In the current study we explore the feasibility and preliminary efficacy of a multimodal, web-based, quit smoking intervention delivered to PLWH smokers via their smartphones. PMID- 30285150 TI - Effect of Hidden Relatedness on Single-Step Genetic Evaluation in an Advanced Open-Pollinated Breeding Program. AB - Open-pollinated (OP) mating is frequently used in forest tree breeding due to the relative temporal and financial efficiency of the approach. The trade-off is the lower precision of the estimated genetic parameters. Pedigree/sib-ship reconstruction has been proven as a tool to correct and complete pedigree information and to improve the precision of genetic parameter estimates. Our study analyzed an advanced generation Eucalyptus population from an OP breeding program using single-step genetic evaluation. The relationship matrix inferred from sib-ship reconstruction was used to rescale the marker-based relationship matrix (G matrix). This was compared with a second scenario that used rescaling based on the documented pedigree. The proposed single-step model performed better with respect to both model fit and the theoretical accuracy of breeding values. We found that the prediction accuracy was superior when using the pedigree information only when compared with using a combination of the pedigree and genomic information. This pattern appeared to be mainly a result of accumulated unrecognized relatedness over several breeding cycles, resulting in breeding values being shrunk toward the population mean. Using biased, pedigree-based breeding values as the base with which to correlate predicted GEBVs, resulted in the underestimation of prediction accuracies. Using breeding values estimated on the basis of sib-ship reconstruction resulted in increased prediction accuracies of the genotyped individuals. Therefore, selection of the correct base for estimation of prediction accuracy is critical. The beneficial impact of sib-ship reconstruction using G matrix rescaling was profound, especially in traits with inbreeding depression, such as stem diameter. PMID- 30285152 TI - Bacillus amyloliquefaciens spray improves the growth performance, immune status, and respiratory mucosal barrier in broiler chickens. AB - Studies have shown that supplementing probiotics in a nasal spray can provide prophylaxis against upper respiratory tract infections. Previously, we found that spraying with Bacillus reduced the concentration of atmospheric ammonia and airborne microbiological aerosols in broiler houses. In the present study, we evaluated the effects of spraying with Bacillus amyloliquefaciens on the respiratory mucosal barrier in broilers. Two trails were conducted simultaneously in four environmentally controlled chambers. In each trail, 320 1-d-old male broilers were randomly assigned to control (CON) and B. amyloliquefaciens (BAQ) group. Eight cages containing 20 birds per cage were placed in two chambers. The BAQ group chambers were sprayed with B. amyloliquefaciens at 4 * 109 CFU/m2 each day for 42 d. Spraying with B. amyloliquefaciens increased average daily gain and average daily feed intake in broilers (P < 0.01), but had no effects on FCR (P > 0.05). The relative weights of the bursa (21 d) and spleen (42 d) were higher in the BAQ group (P < 0.05). The serum IgG, IgM (21 d), and IgA, Ig M (42 d) levels were improved in BAQ group (P < 0.05). The sIgA levels in tracheal lavage fluid were significantly higher in the BAQ group than the CON group (P < 0.05). Furthermore, treatment with BAQ downregulated IL-6 and IFN-gamma (P < 0.05), but upregulated IL-2, occludin, and mucin-2 (P < 0.05). In addition, the number of acidic goblet cells was significantly higher in the tracheas of treated broilers than untreated broilers (P < 0.05). In conclusion, spraying with B. amyloliquefaciens may help to enhance the growth performance and improve the respiratory mucosal barrier in broiler chickens. PMID- 30285155 TI - Endoplasmic reticulum stress affected chondrocyte apoptosis in femoral head necrosis induced by glucocorticoid in broilers. AB - In our previous study, chondrocyte apoptosis in femoral head necrosis (FHN) affected broilers was found to be associated with the endoplasmic reticulum stress (ERS) signaling pathway. In the present study, we further explored the role of ERS-induced chondrocyte apoptosis in FHN-affected broilers and the parallel test was carried out with articular chondrocytes cultivated in vitro. The broilers and chondrocytes were treated with methylprednisolone (MP). The main pathological changes in FHN-affected broilers included the proximal femoral head separated from its articular cartilage and growth plate lesions. MP-treated chondrocytes demonstrated morphology changes, cell viability reduction, secretory capacity dysfunction, and apoptosis. The mRNA expressions of pro-apoptotic genes controlled by ERS signaling pathway were up-regulated both in vivo and in vitro experiments. It showed that MP induced FHN in broilers, activated apoptosis related genes on ERS signaling pathway, and affected the survival and apoptosis of chondrocytes, and bone growth. PMID- 30285153 TI - Nonfilament-forming RecA dimer catalyzes homologous joint formation. AB - Homologous recombination is essential to genome maintenance, and also to genome diversification. In virtually all organisms, homologous recombination depends on the RecA/Rad51-family recombinases, which catalyze ATP-dependent formation of homologous joints-critical intermediates in homologous recombination. RecA/Rad51 binds first to single-stranded (ss) DNA at a damaged site to form a spiral nucleoprotein filament, after which double-stranded (ds) DNA interacts with the filament to search for sequence homology and to form consecutive base pairs with ssDNA ('pairing'). How sequence homology is recognized and what exact role filament formation plays remain unknown. We addressed the question of whether filament formation is a prerequisite for homologous joint formation. To this end we constructed a nonpolymerizing (np) head-to-tail-fused RecA dimer (npRecA dimer) and an npRecA monomer. The npRecA dimer bound to ssDNA, but did not form continuous filaments upon binding to DNA; it formed beads-on-string structures exclusively. Although its efficiency was lower, the npRecA dimer catalyzed the formation of D-loops (a type of homologous joint), whereas the npRecA monomer was completely defective. Thus, filament formation contributes to efficiency, but is not essential to sequence-homology recognition and pairing, for which a head-to tail dimer form of RecA protomer is required and sufficient. PMID- 30285156 TI - Effects of caponization and age on the histology, lipid localization, and fiber diameter in muscles from Leghorn cockerels. AB - Poultry researchers seek general and native lines of birds for capon production. The primary aim is to find high-quality meat with valuable sensory attributes. Castration decreases androgen levels and changes lipid metabolism, resulting in the accumulation of abdominal, subcutaneous, and intramuscular fat, which changes the flavor, texture, and tenderness of the meat. Histological analysis of selected skeletal muscles from Leghorn capons and cockerels was the main aim of the present study, along with examination of lipid localization in muscle tissue. We also assessed fiber type and diameter in the pectoral muscles (pectoralis major). The experiment was performed on 200 Leghorn cockerels; testes were removed at 8 wk of age. At 12, 16, 20, 24, and 28 wk of age, 6 cockerels and 6 capons were slaughtered, and samples from the pectoral and thigh muscles were evaluated. Differences in the focal necrosis of the fibers with infiltration of lymphoid cells (P < 0.05) were observed in thigh muscles, with higher numbers in cockerels than in capons. All examined locations in the pectoral and thigh muscles of capons (around the blood vessels, in the perimysium, in the endomysium, and in the sarcoplasm) showed higher concentrations of lipids compared to levels in cockerels. The analysis of fiber type in pectoralis major muscles revealed that all fibers were type IIB. The diameters of the fibers of the pectoral muscles were different (P < 0.05) at 28 wk of age, and the diameters of the giant fibers were different (P < 0.05) at 16 wk of age. The high concentration of lipids in the skeletal muscles of Leghorn capons is remarkable. Thus, ethical reasons as well as economic reasons should be considered when one day-old cockerels are eliminated. PMID- 30285154 TI - Why are Hoogsteen base pairs energetically disfavored in A-RNA compared to B-DNA? AB - A(syn)-U/T and G(syn)-C+ Hoogsteen (HG) base pairs (bps) are energetically more disfavored relative to Watson-Crick (WC) bps in A-RNA as compared to B-DNA by >1 kcal/mol for reasons that are not fully understood. Here, we used NMR spectroscopy, optical melting experiments, molecular dynamics simulations and modified nucleotides to identify factors that contribute to this destabilization of HG bps in A-RNA. Removing the 2'-hydroxyl at single purine nucleotides in A RNA duplexes did not stabilize HG bps relative to WC. In contrast, loosening the A-form geometry using a bulge in A-RNA reduced the energy cost of forming HG bps at the flanking sites to B-DNA levels. A structural and thermodynamic analysis of purine-purine HG mismatches reveals that compared to B-DNA, the A-form geometry disfavors syn purines by 1.5-4 kcal/mol due to sugar-backbone rearrangements needed to sterically accommodate the syn base. Based on MD simulations, an additional penalty of 3-4 kcal/mol applies for purine-pyrimidine HG bps due to the higher energetic cost associated with moving the bases to form hydrogen bonds in A-RNA versus B-DNA. These results provide insights into a fundamental difference between A-RNA and B-DNA duplexes with important implications for how they respond to damage and post-transcriptional modifications.

AB - Importance: Despite recent studies suggesting arthroscopic partial meniscectomy (APM) is not more effective than physical therapy (PT), the procedure is still frequently performed in patients with meniscal tears. Objective: To assess whether PT is noninferior to APM for improving patient-reported knee function in patients with meniscal tears. Design, Setting, and Participants: Noninferiority, multicenter, randomized clinical trial conducted in 9 hospitals in the Netherlands. Participants were aged 45 to 70 years with nonobstructive meniscal tears (ie, no locking of the knee joint). Patients with knee instability, severe osteoarthritis, and body mass index greater than 35 were excluded. Recruitment took place between July 17, 2013, and November 4, 2015. Participants were followed up for 24 months (final participant follow-up, October 11, 2017). Interventions: Three hundred twenty-one participants were randomly assigned to APM (n = 159) or a predefined PT protocol (n = 162). The PT protocol consisted of 16 sessions of exercise therapy over 8 weeks focused on coordination and closed kinetic chain strength exercises. Main Outcomes and Measures: The primary outcome was change in patient-reported knee function on the International Knee Documentation Committee Subjective Knee Form (range, 0 to 100; from worse to best) from baseline over a 24-month follow-up period. The noninferiority margin was defined as a difference between treatment groups of 8 points and was assessed with a 1-sided alpha of .025. The primary analysis followed the intention-to treat principle. Results: Among 321 patients who were randomized (mean [SD] age, 58 [6.6] years; 161 women [50%]), 289 (90%) completed the trial (161 women and 158 men). In the PT group, 47 participants (29%) had APM during the 24-month follow-up period, and 8 participants randomized to APM (5%) did not have APM. Over a 24-month follow-up period, knee function improved in the APM group by 26.2 points (from 44.8 to 71.5) and in the PT group by 20.4 points (from 46.5 to 67.7). The overall between-group difference was 3.6 points (97.5% CI, -infinity to 6.5; P value for noninferiority = .001). Adverse events occurred in 18 participants in the APM group and 12 in the PT group. Repeat surgery (3 in the APM group and 1 in the PT group) and additional outpatient visits for knee pain (6 in the APM group and 2 in the PT group) were the most frequent adverse events. Conclusions and Relevance: Among patients with nonobstructive meniscal tears, PT was noninferior to APM for improving patient-reported knee function over a 24 month follow-up period. Based on these results, PT may be considered an alternative to surgery for patients with nonobstructive meniscal tears. Trial Registration: ClinicalTrials.gov Identifier: NCT01850719. PMID- 30285178 TI - Association of Clinical and Social Factors With Excess Hypertension Risk in Black Compared With White US Adults. AB - Importance: The high prevalence of hypertension among the US black population is a major contributor to disparities in life expectancy; however, the causes for higher incidence of hypertension among black adults are unknown. Objective: To evaluate potential factors associated with higher risk of incident hypertension among black adults. Design, Setting, and Participants: Prospective cohort study of black and white adults selected from a longitudinal cohort study of 30 239 participants as not having hypertension at baseline (2003-2007) and participating in a follow-up visit 9.4 years (median) later. Exposures: There were 12 clinical and social factors, including score for the Southern diet (range, -4.5 to 8.2; higher values reflect higher level of adherence to the dietary pattern), including higher fried and related food intake. Main Outcomes and Measures: Incident hypertension (systolic blood pressure >=140 mm Hg, diastolic blood pressure >=90 mm Hg, or use of antihypertensive medications) at the follow-up visit. Results: Of 6897 participants (mean [SD] age, 62 [8] years; 26% were black adults; and 55% were women), 46% of black participants and 33% of white participants developed hypertension. Black men had an adjusted mean Southern diet score of 0.81 (95% CI, 0.72 to 0.90); white men, -0.26 (95% CI, -0.31 to -0.21); black women, 0.27 (95% CI, 0.20 to 0.33); and white women, -0.57 (95% CI, -0.61 to -0.54). The Southern diet score was significantly associated with incident hypertension for men (odds ratio [OR], 1.16 per 1 SD [95% CI, 1.06 to 1.27]; incidence of 32.4% at the 25th percentile and 36.1% at the 75th percentile; difference, 3.7% [95% CI, 1.4% to 6.2%]) and women (OR, 1.17 per 1 SD [95% CI, 1.08 to 1.28]; incidence of 31.0% at the 25th percentile and 34.8% at the 75th percentile; difference, 3.8% [95% CI, 1.5% to 5.8%]). The Southern dietary pattern was the largest mediating factor for differences in the incidence of hypertension, accounting for 51.6% (95% CI, 18.8% to 84.4%) of the excess risk among black men and 29.2% (95% CI, 13.4% to 44.9%) of the excess risk among black women. Among black men, a higher dietary ratio of sodium to potassium and an education level of high school graduate or less each mediated 12.3% of the excess risk of incident hypertension. Among black women, higher body mass index mediated 18.3% of the excess risk; a larger waist, 15.2%; less adherence to the Dietary Approaches to Stop Hypertension diet, 11.2%; income level of $35 000 or less, 9.3%; higher dietary ratio of sodium to potassium, 6.8%; and an education level of high school graduate or less, 4.1%. Conclusions and Relevance: In a mediation analysis comparing incident hypertension among black adults vs white adults in the United States, key factors statistically mediating the racial difference for both men and women included Southern diet score, dietary ratio of sodium to potassium, and education level. Among women, waist circumference and body mass index also were key factors. PMID- 30285182 TI - Nurturing Medicine. PMID- 30285180 TI - Tinea Versicolor. PMID- 30285183 TI - Diagnosis and Management of Rheumatoid Arthritis: A Review. AB - Importance: Rheumatoid arthritis (RA) occurs in about 5 per 1000 people and can lead to severe joint damage and disability. Significant progress has been made over the past 2 decades regarding understanding of disease pathophysiology, optimal outcome measures, and effective treatment strategies, including the recognition of the importance of diagnosing and treating RA early. Observations: Early diagnosis and treatment of RA can avert or substantially slow progression of joint damage in up to 90% of patients, thereby preventing irreversible disability. The development of novel instruments to measure disease activity and identify the presence or absence of remission have facilitated new treatment strategies to arrest RA before joints are damaged irreversibly. Outcomes have been improved by recognizing the benefits of early diagnosis and early therapy with disease-modifying antirheumatic drugs (DMARDs). The treatment target is remission or a state of at least low disease activity, which should be attained within 6 months. Methotrexate is first-line therapy and should be prescribed at an optimal dose of 25 mg weekly and in combination with glucocorticoids; 40% to 50% of patients reach remission or at least low disease activity with this regimen. If this treatment fails, sequential application of targeted therapies, such as biologic agents (eg, tumor necrosis factor [TNF] inhibitors) or Janus kinase inhibitors in combination with methotrexate, have allowed up to 75% of these patients to reach the treatment target over time. New therapies have been developed in response to new pathogenetic findings. The costs of some therapies are considerable, but these costs are decreasing with the advent of biosimilar drugs (drugs essentially identical to the original biologic drugs but usually available at lower cost). Conclusions and Relevance: Scientific advances have improved therapies that prevent progression of irreversible joint damage in up to 90% of patients with RA. Early treatment with methotrexate plus glucocorticoids and subsequently with other DMARDs, such as inhibitors of TNF, IL-6, or Janus kinases, improves outcomes and prevents RA-related disability. A treat-to-target strategy aimed at reducing disease activity by at least 50% within 3 months and achieving remission or low disease activity within 6 months, with sequential drug treatment if needed, can prevent RA-related disability. PMID- 30285179 TI - Association of Thyroid Hormone Therapy With Quality of Life and Thyroid-Related Symptoms in Patients With Subclinical Hypothyroidism: A Systematic Review and Meta-analysis. AB - Importance: The benefit of thyroid hormone therapy for subclinical hypothyroidism is uncertain. New evidence from recent large randomized clinical trials warrants an update of previous meta-analyses. Objective: To conduct a meta-analysis of the association of thyroid hormone therapy with quality of life and thyroid-related symptoms in adults with subclinical hypothyroidism. Data Sources: PubMed, EMBASE, ClinicalTrials.gov, Web of Science, Cochrane Library, CENTRAL, Emcare, and Academic Search Premier from inception until July 4, 2018. Study Selection: Randomized clinical trials that compared thyroid hormone therapy with placebo or no therapy in nonpregnant adults with subclinical hypothyroidism were eligible. Two reviewers independently evaluated eligibility based on titles and abstracts of all retrieved studies. Studies not excluded in this first step were independently assessed for inclusion after full-text evaluation by 2 reviewers. Data Extraction and Synthesis: Two independent reviewers extracted data, assessed risk of bias (Cochrane risk-of-bias tool), and evaluated the quality of evidence (GRADE tool). For synthesis, differences in clinical scores were transformed (eg, quality of life) into standardized mean differences (SMDs; positive values indicate benefit of thyroid hormone therapy; 0.2, 0.5, and 0.8 correspond to small, moderate, and large effects, respectively). Random-effects models for meta analyses were applied. Main Outcomes and Measures: General quality of life and thyroid-related symptoms after a minimum follow-up of 3 months. Results: Overall, 21 of 3088 initially identified publications met the inclusion criteria, with 2192 adults randomized. After treatment (range, 3-18 months), thyroid hormone therapy was associated with lowering the mean thyrotropin value into the normal reference range compared with placebo (range, 0.5-3.7 mIU/L vs 4.6 to 14.7 mIU/L) but was not associated with benefit regarding general quality of life (n = 796; SMD, -0.11; 95% CI, -0.25 to 0.03; I2=66.7%) or thyroid-related symptoms (n = 858; SMD, 0.01; 95% CI, -0.12 to 0.14; I2=0.0%). Overall, risk of bias was low and the quality of evidence assessed with the GRADE tool was judged moderate to high. Conclusions and Relevance: Among nonpregnant adults with subclinical hypothyroidism, the use of thyroid hormone therapy was not associated with improvements in general quality of life or thyroid-related symptoms. These findings do not support the routine use of thyroid hormone therapy in adults with subclinical hypothyroidism. PMID- 30285186 TI - Brief report of a tablet-delivered psychosocial intervention for men with advanced prostate cancer: Acceptability and efficacy by race. AB - Relative to non-Hispanic whites (NHW), black men are disproportionately affected by prostate cancer (PC) incidence, have poorer PC outcomes, and report greater compromises in health-related quality of life. Despite these challenges, black men are underrepresented in psychosocial cancer research, possibly due to limited access to supportive oncology programs. The purpose of this article is to examine the acceptability and efficacy for reducing disease-specific distress of a tablet delivered psychosocial intervention for older men with advanced PC (APC) and explore differences by race. Men with APC (N = 192, 37.5% black, age M = 68.84 years) were randomized to 10-week Cognitive Behavioral Stress Management (CBSM) or attention-control Health Promotion (HP), both delivered via tablets. Assessments occurred at baseline in person, weekly during the 10-week program via tablets, and at 6 and 12 months in person. Weekly session evaluations and postprogram exit surveys assessed acceptability. Efficacy was assessed with a measure of PC-anxiety validated with racially diverse PC patients using linear mixed effects modeling. Study retention and group attendance did not differ by race. CBSM and HP were both acceptable among older APC patients. Black men rated both conditions more favorably than NHW men. Men in CBSM (vs. HP) reported greater reductions in PC-anxiety at 6 months (not sustained at 12 months). Black men in CBSM reported greater decreases in PC-anxiety over time compared with all other groups. Tablet-delivered CBSM and HP were acceptable for black and NHW APC patients, although black men rated both conditions more favorably. Black men reported a unique intervention benefit related to reduced disease-specific distress. PMID- 30285187 TI - Effects of dietary supplementation with Clostridium butyricum on laying performance, egg quality, serum parameters, and cecal microflora of laying hens in the late phase of production. AB - This experiment was conducted to evaluate the effects of dietary supplementation with Clostridium butyricum on laying performance, egg quality, serum parameters, and cecal microflora of laying hens in the late phase of production. Jinghong-1 strain laying hens (n = 960; 48 wk of age) were randomly allocated to 5 treatment groups with 6 replicates of 32 hens. Hens were fed with basal diet (control) and basal diet supplemented with 2.5 * 104 (CB1), 5 * 104 (CB2), 1 * 105 (CB3), and 2 * 105 (CB4) cfu/g C. butyricum for 10 wk. The results showed that egg production, egg mass, and eggshell strength increased quadratically as supplemental C. butyricum increased, and these responses were maximized in the CB2 group (P < 0.05). Compared with the control group, the addition of C. butyricum resulted in quadratic effects on serum total protein, uric acid, calcium, complement component C3 and catalase concentrations, and these responses were maximized or minimized in the CB2 group (P < 0.05). Linear and quadratic increases were observed in serum IgM, total superoxide dismutase, and glutathione peroxidase concentrations, and these responses were maximized in CB2 or CB3 group (P < 0.05). The addition of C. butyricum in the CB2 group resulted in linearly increasing levels of serum IgG concentration as compared with the control group (P < 0.05). Spleen index increased (P < 0.05) in the CB2 group. Hens fed with C. butyricum reduced (P > 0.05) the population of E. coli, while Bifidobacterium counts increased quadratically and maximized in the CB2 group (P < 0.05). In conclusion, the results indicated that dietary supplementation with C. butyricum (5 * 104 or 1 * 105 cfu/g) could improve laying performance and egg quality by promoting immune function, enhancing antioxidative capacity, and benefiting the cecal microflora of laying hens in the late phase of production. PMID- 30285188 TI - The effect of some natural alternative to antibiotics on growth and changes in intestinal histology in broiler exposed to Salmonella challenge. AB - This study was conducted to find the effect of different feed additives on the production performance and intestinal histology in Salmonella challenged birds. A total of 600 day-old-broiler chicks (Ross 308) were assignment to 10 treatments. Each treatment was further divided into 10 replicates. The chicks were randomly divided into one of the following 10 treatments as follow: Negative control; positive control infected with Salmonella enterica subsp. typhimurium; T1, infected + avilamycin at the rate of 0.2 g/kg; T2, infected + probiotic having viable spores (2 * 107 CFU/g) of Bacillus subtilis (ATCC PTA-6737); T3, infected + Sanguinarine consisting of benzo phenanthridine alkaloids from Macleaya cordata; T4, B. subtilis (ATCC PTA-6737) + Sanguinarine; T5, infected + B. subtilis 500 g/T of feed (1.2 * 106 cfu/g); T6, prebiotic, Saccharomyces boulardii (1 * 108cfu/g); T7, infected + oregano at the rate of 1 g/kg; T8, infected + thermally processed clay calcium montmorillonite. The results showed that feed intake was significantly (P < 0.01) high in negative control and T2 compared to the positive control. Body weight gain was significantly (P < 0.01) higher in negative control and significantly (P < 0.05) low in T8. Feed conversion ratio was significantly (P < 0.05) high in negative control and significanlty (P < 0.05) high in T6. Similarly, PEF was also significantly (P < 0.05) high in negative control and significantly (P < 0.05) low in positive control and T8. Villus width was significantly (P < 0.05) high in negative control followed by T8. Dietary supplementation of different feed additives may be useful in broiler chicks challenged with Salmonella infection. PMID- 30285185 TI - Progressing super-enhancer landscape during mammary differentiation controls tissue-specific gene regulation. AB - The mammary luminal lineage relies on the common cytokine-sensing transcription factor STAT5 to establish super-enhancers during pregnancy and initiate a genetic program that activates milk production. As pups grow, the greatly increasing demand for milk requires progressive differentiation of mammary cells with advancing lactation. Here we investigate how persistent hormonal exposure during lactation shapes an evolving enhancer landscape and impacts the biology of mammary cells. Employing ChIP-seq, we uncover a changing transcription factor occupancy at mammary enhancers, suggesting that their activities evolve with advancing differentiation. Using mouse genetics, we demonstrate that the functions of individual enhancers within the Wap super-enhancer evolve as lactation progresses. Most profoundly, a seed enhancer, which is mandatory for the activation of the Wap super-enhancer during pregnancy, is not required during lactation, suggesting compensatory flexibility. Combinatorial deletions of structurally equivalent constituent enhancers demonstrated differentiation specific compensatory activities during lactation. We also demonstrate that the Wap super-enhancer, which is built on STAT5 and other common transcription factors, retains its exquisite mammary specificity when placed into globally permissive chromatin, suggesting a limited role of chromatin in controlling cell specificity. Our studies unveil a previously unrecognized progressive enhancer landscape where structurally equivalent components serve unique and differentiation-specific functions. PMID- 30285189 TI - Opioid, antipsychotic and hypnotic use in end of life in long-term care facilities in six European countries: results of PACE. AB - Background: Opioids, antipsychotics and hypnotics are recommended for comfort care in dying. We studied their prescription during the last 3 days in residents deceased in the long-term care facility (LTCF). Methods: In a retrospective, cross-sectional survey in Belgium, England, Finland, Italy, the Netherlands and Poland, LTCFs, selected by proportional stratified random sampling, reported all deaths over the previous 3 months. The nurse most involved in the residents' care reviewed the chart for opioid, antipsychotic and hypnotic prescription, cause of death and comorbidities. Multivariable logistic regression was performed to adjust for resident characteristics. Results: Response rate was 81.6%. We included 1079 deceased residents in 322 LCTFs. Opioid prescription ranged from 18.5% (95% CI: 13.0-25.8) of residents in Poland to 77.9% (95% CI: 69.5-84.5) in the Netherlands, antipsychotic prescription from 4.8% (95% CI: 2.4-9.1) in Finland to 22.4% (95% CI: 14.7-32.4) in Italy, hypnotic prescription from 7.8% (95% CI: 4.6-12.8) in Finland to 47.9% (95% CI: 38.5-57.3) in the Netherlands. Differences in opioid, antipsychotic and hypnotic prescription between countries remained significant (P < 0.001) when controlling for age, gender, length of stay, cognitive status, cause of death in multilevel, multivariable analyses. Dying from cancer showed higher odds for receiving opioids (OR 3.51; P < 0.001) and hypnotics (OR 2.10; P = 0.010). Conclusions: Opioid, antipsychotic and hypnotic prescription in the dying phase differed significantly between six European countries. Further research should determine the appropriateness of their prescription and refine guidelines especially for LTCF residents dying of non-cancer diseases.

PMID- 30285208 TI - Should This Woman With Dense Breasts Receive Supplemental Breast Cancer Screening?: Grand Rounds Discussion From Beth Israel Deaconess Medical Center. AB - Breast cancer will develop in 12% of women during their lifetime and is the second leading cause of cancer death among U.S. women. Mammography is the most commonly used tool to screen for breast cancer. Considerable uncertainty exists regarding the age at which to begin screening and the optimal screening interval. Breast density is a risk factor for breast cancer. In addition, for women with dense breasts, small tumors may be missed on mammography and the sensitivity of screening is diminished. At the time of publication, 35 states had passed laws mandating that breast density be reported in the letters that radiologists send to women with their mammogram results. The mandated language may be challenging for patients to understand, and such reporting may increase worry for women who are told that their risk for breast cancer is higher than average on the basis of breast density alone. The U.S. Preventive Services Task Force and the American College of Radiology (ACR) have each issued guidelines that address breast cancer screening for women with dense breasts. Both organizations found insufficient evidence to recommend for or against magnetic resonance screening, whereas the ACR advises consideration of ultrasonography for supplemental screening. In this Beyond the Guidelines, 2 experts-a radiologist and a general internist-discuss these controversies. In particular, the discussants review the role of supplemental breast cancer screening, including breast ultrasonography or magnetic resonance imaging for women with dense breasts. Finally, the experts offer specific advice for a patient who finds her mammography reports confusing. PMID- 30285209 TI - Clostridioides difficile Infection. AB - Clostridioides difficile (formerly Clostridium difficile) infection is the most frequently identified health care-associated infection in the United States. C difficile has also emerged as a cause of community-associated diarrhea, resulting in increased incidence of community-associated infection. Clinical illness ranges in severity from mild diarrhea to fulminant colitis and death. Appropriate management of infection requires understanding of the various diagnostic assays and therapeutic options as well as relevant measures to infection prevention. This article provides updated recommendations regarding the prevention, diagnosis, and treatment of incident and recurrent C difficile infection.

PMID- 30285230 TI - Female adiposity and time-to-pregnancy: a multiethnic prospective cohort. AB - STUDY QUESTION: Are higher overall and central adiposity associated with reduced fecundability, measured by time-to-pregnancy (TTP), in Asian women? SUMMARY ANSWER: Higher overall adiposity, but not central adiposity, was associated with longer TTP in Asian women. WHAT IS KNOWN ALREADY: High body mass index (BMI) has been associated with a longer TTP, although the associations of body composition and distribution with TTP are less clear. There are no previous studies of TTP in Asian women, who have a relatively higher percentage of body fat and abdominal fat at relatively lower BMI. STUDY DESIGN, SIZE, DURATION: Prospective preconception cohort using data from 477 Asian (Chinese, Malay and Indian) women who were planning to conceive and enrolled in the Singapore PREconception Study of long-Term maternal and child Outcomes (S-PRESTO) study, 2015-2017. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women's mean age was 30.7 years. Overall adiposity was assessed by BMI, sum of 4-site skinfold thicknesses (SFT) and total body fat percentage (TBF%, measured using air displacement plethysmography); central adiposity was assessed by waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR) and A body Shape Index (ABSI). Pregnancy occurring within one year from recruitment was ascertained by ultrasonography. Those who did not conceive within one year of recruitment, were lost to follow-up, or initiated fertility treatment were censored. TTP was measured in cycles. Discrete-time proportional hazards models were used to estimate the fecundability ratio (FR) and 95% confidence interval (CI) for each anthropometric measure in association with fecundability, adjusting for confounders. MAIN RESULTS AND THE ROLE OF CHANCE: Compared to women with a normal BMI of 18.5-22.9 kg/m2, women with higher BMI of 23-27.4 and >=27.5 kg/m2 showed lower FR of 0.66 (95% CI 0.45, 0.97) and 0.53 (0.31, 0.89), respectively. Compared to women in the lowest quartile of SFT (25-52.9 mm), those in the highest quartile of >=90.1 mm showed lower FR of 0.58 (95% CI 0.36, 0.95). Compared to women in the lowest quartile of TBF% (13.6-27.2%), those in the upper two quartiles of 33.0-39.7% and >=39.8% showed lower FR of 0.56 (95% CI 0.32, 0.98) and 0.43 (0.24, 0.80), respectively. Association of high BMI with reduced fecundability was particularly evident among nulliparous women. Measures of central adiposity (WC, WHR, WHtR, ABSI) were not associated with fecundability. LIMITATIONS REASONS FOR CAUTION: Small sample size could restrict power of analysis.The analysis was confined to planned pregnancies, which could limit generalizability of findings to non-planned pregnancies, estimated at around 44% in Singapore. Information on the date of last menstrual period for each month was not available, hence the accuracy of self-reported menstrual cycle length could not be validated, potentially introducing error into TTP estimation. Measures of exposures and covariates such as cycle length were not performed repeatedly over time; cycle length might have changed during the period before getting pregnant. WIDER IMPLICATIONS OF THE FINDINGS: Other than using BMI as the surrogate measure of body fat, we provide additional evidence showing that higher amounts of subcutaneous fat that based on the measure of SFT at the sites of biceps, triceps, suprailiac and subscapular, and TBF% are associated with longer TTP. Achieving optimal weight and reducing total percentage body fat may be a potential intervention target to improve female fertility. The null results observed between central adiposity and TTP requires confirmation in further studies.

TRIAL REGISTRATION NUMBER: N/A. PMID- 30285232 TI - The clinical utility of point-of-care tests for influenza in ambulatory care: A systematic review and meta-analysis. AB - Background: Point-of-care tests (POCTs) for influenza are diagnostically superior to clinical diagnosis, but their impact on patient outcomes is unclear. Methods: A systematic review of influenza POCTs versus usual care in ambulatory care settings. Studies were identified by searching six databases and assessed using the Cochrane risk of bias tool. Estimates of risk ratios (RR), standardised mean differences, 95% confidence intervals and I2 were obtained by random effects meta analyses. We explored heterogeneity with sensitivity analyses and meta regression. Results: 12,928 citations were screened. Seven randomised studies (n=4,324) and six non-randomised studies (n=4,774) were included. Most evidence came from paediatric emergency departments. Risk of bias was moderate in randomised studies and higher in non-randomised studies. In randomised trials, POCTs had no effect on admissions (RR 0.93, 95% CI 0.61-1.42, I2=34%), returning for care (RR 1.00 95% CI=0.77-1.29, I2=7%), or antibiotic prescribing (RR 0.97, 95% CI 0.82-1.15, I2=70%), but increased prescribing of antivirals (RR 2.65, 95% CI 1.95-3.60; I2=0%). Further testing was reduced for full blood counts (FBC) (RR 0.80, 95% CI 0.69-0.92 I2=0%), blood cultures (RR 0.82, 95% CI 0.68-0.99; I2=0%) and chest radiography (RR 0.81, 95% CI 0.68-0.96; I2=32%), but not urinalysis (RR 0.91, 95% CI 0.78-1.07; I2=20%). Time in the emergency department was not changed. Fewer non-randomised studies reported these outcomes, with some findings reversed or attenuated (fewer antibiotic prescriptions and less urinalysis in tested patients). Conclusions: Point-of-care testing for influenza influences prescribing and testing decisions, particularly for children in emergency departments. Observational evidence shows challenges for real-world implementation. PMID- 30285231 TI - Cognitive control and network disruption in remitted depression: a correlate of childhood adversity. AB - Individuals in a major depressive episode often display impairment in cognitive control, and this impairment exists outside of the acute phase of illness. Impairment in cognitive control also has been associated with exposure to childhood adversity (CA). The current study examined whether exposure to CA can explain variance in a component of cognitive control-inhibitory control independent of diagnostic status in young adults with and without a history of depression. Healthy control individuals (n = 40) and individuals with remitted major depressive disorder (n = 53) completed a task measuring inhibitory control, reported level of CA and completed a scanning session to assess gray matter volume and resting state connectivity in regions associated with cognitive control. The results demonstrate that higher levels of CA were associated with poorer inhibitory control, reduced right middle frontal gyrus gray matter, decreased connectivity of salience and emotion networks and increased connectivity in cognitive control networks, even after controlling for diagnostic status, residual depression symptoms and current stressors. Together, the results suggest that inhibitory control impairment and intrinsic connectivity changes may be characterized as developmental sequelae of early stress exposure. PMID- 30285233 TI - Neuromuscular Attributes Associated With Lower Extremity Mobility Among Community Dwelling Older Adults. AB - Background: The Short Physical Performance Battery (SPPB) is advocated as a screening tool in geriatric care for predicting future disability. We aimed to identify the leg neuromuscular attributes to be targeted in rehabilitative care among older adults with poor SPPB scores. Methods: Boston Rehabilitative Impairment Study of the Elderly (Boston RISE) participants (n = 430) underwent assessment of neuromuscular attributes (leg strength, leg velocity, trunk extensor endurance, knee flexion range of motion [ROM], ankle ROM, and foot sensation). Linear regression models examined association between each neuromuscular attribute and SPPB, adjusting for age, race, gender, comorbidity, body mass index, depression, cognition, and other neuromuscular attributes. Results: Participants with 1 SD unit higher leg strength, leg velocity, and trunk extensor endurance had 0.52, 0.30, and 0.52 points higher SPPB total score. Participants with ankle ROM impairment and foot sensory loss had 0.43 and 0.57 lower SPPB total score compared with those without these. Leg strength and trunk extensor endurance were associated with balance; leg velocity, trunk extensor endurance, and ankle ROM were associated with gait speed; and strength, trunk extensor endurance, knee ROM, and feet sensation were associated with chair stand score. Neuromuscular attributes, along with covariates, explained 40.4% of the variance in the total SPPB score, a substantial increase over the 22.7% variance explained by covariates alone. Conclusions: Neuromuscular attributes affect mobility performance in older patients as measured by the SPPB. Specific impairments are associated with poor performance in specific component scores.

AB - Epidemiological, molecular and genetic studies have indicated high serum vitamin D levels are associated with lower risk of several autoimmune diseases. The Vitamin D Receptor (VDR) binding sites in monocytes and dendritic cells (DCs) are more common in risk genes for diseases with latitude-dependence than in risk genes for other diseases. The transcription factor genes ZMIZ1 and IRF8 - risk genes for many of these diseases - have VDR binding peaks co-incident with the risk SNPs. We show these genes are responsive to vitamin D: ZMIZ1 expression increased and IRF8 expression decreased, and this response was affected by genotype in different cell subsets. The IL10/IL12 ratio in tolerogenic DCs increased with vitamin D. These data indicate that vitamin D regulation of ZMIZ1 and IRF8 in DCs and monocytes contribute to latitude-dependent autoimmune disease risk. PMID- 30285235 TI - Nurses are critical in aiding patients transitioning to biosimilars in inflammatory bowel disease: education and communication strategies. AB - The increasing prevalence of inflammatory bowel disease and the high costs associated with biological therapies suggest that biologicals with lower costs, but no compromise on efficacy and safety, should be considered when developing a treatment plan for inflammatory bowel disease. Biosimilars offer a more cost effective alternative, and although the European Medicines Agency has approved the use of biosimilars for many indications, including inflammatory bowel disease, patients may be concerned about the safety and efficacy of these agents. The updated Nurses-European Crohn's and Colitis Organisation statements, published in March 2018, recommend that inflammatory bowel disease nurses facilitate patient choice of biological or biosimilar therapy. Nurses are pivotal in managing the challenges associated with patients transitioning to biosimilars. However, there is limited information available on how inflammatory bowel disease nurses can communicate the concept of biosimilars to patients and also on how best to support them before and during the switch from originators. This review article will focus on patients' concerns regarding biosimilars and describe considerations for nurses when supporting patients transitioning from originators to biosimilars. Through nurse-led patient education and the use of structured communication strategies as well as investment into managed switching programmes, patients will become more confident and adherent to their biosimilar therapy, and this may lead to overall reductions in healthcare expenditure for inflammatory bowel disease. PMID- 30285236 TI - Catfish mucus alters the Flavobacterium columnare transcriptome. AB - Columnaris disease, caused by Flavobacterium columnare, severely impacts the production of freshwater finfish species. Therefore, efforts to better understand the biological processes of F. columnare, including the formation of biofilms and their contribution to disease, are ongoing. In this study, we incubated F. columnare cultures with channel catfish mucus and used high-throughput RNA sequencing to evaluate global changes in gene expression. Our data show that mucus activates in vitro biofilm formation. The analysis of F. columnare transcriptomes after the addition of mucus revealed significant differentially expressed genes (DEGs) between the planktonic and biofilm states. DEGs common among all biofilms were enriched for gene ontology groups including signal transduction, ligand binding and cellular homeostasis and are likely necessary for biofilm formation. Iron acquisition systems included TonB-dependent receptor and ferroxidase genes were expressed among all biofilms, while siderophore synthesis genes were only expressed in mucus-stimulated biofilms. The current analysis of F. columnare transcriptomes adds valuable information about the basic biological processes that occur during the planktonic and biofilm states. This work serves as a basis for future studies on understanding how biofilms are established and how they contribute to disease progression. PMID- 30285237 TI - Genetic Diversity of Deformed Wing Virus From Apis mellifera carnica (Hymenoptera: Apidae) and Varroa Mite (Mesostigmata: Varroidae). AB - Deformed wing virus (DWV) is one of the most widespread viruses that infect honey bee colonies. The route of infection is directly through contaminated food, feces, and air, or indirectly through the varroa mite, which acts as a vector. Positive DWV samples were obtained from Carniolan honey bee (Apis mellifera carnica) colonies and of varroa mites from the whole territory of Slovenia during a survey between 2007 and 2014. Nucleotide sequences of 471 nucleotides for the L protein gene and 573 nucleotides for the helicase gene were compared. High genetic diversity was observed among these Slovenian Carniolan honey bee DWV field samples, as well as with almost all the strains previously found in other countries in Europe. Phylogenetic analyses in two regions of the viral genome show that several of the DWV strains obtained from honey bees and varroa are genetically very closely related, confirming the important role of varroa in the transmission of DWV. Identification of closely related sequences also confirmed that the same strains of DWV have been successfully transmitted between various honey bee colonies and apiaries. It has also been established that simultaneous infection, in one apiary, of honey bees with two or more different strains of DWV is quite frequent. This is phylogenetic study that compares honey bee and varroa DWV strains from Carniolan honeybees. PMID- 30285238 TI - N-acetylmannosamine (ManNAc) supports the growth of Borrelia burgdorferi in the absence of N-acetylglucosamine (GlcNAc). AB - Borrelia burgdorferi, the causative agent of Lyme disease, lacks the ability to biosynthesize many essential nutrients de novo, including N-acetylglucosamine (GlcNAc). This amino sugar is required for cell wall synthesis, and is a component of the complex growth medium used for in vitro propagation. When cultured without free GlcNAc, B. burgdorferi cells exhibit a unique biphasic growth pattern. We hypothesized that genes involved in the GlcNAc starvation response would be differentially expressed when compared to cells cultured in complete medium, and investigated this using transcriptomics. Twenty-one genes were differentially regulated in wild-type and starvation-adapted cells cultured without GlcNAc compared to wild-type cells cultured with GlcNAc. Of those, three genes involved in carbohydrate utilization were upregulated: bbb04 (chbC) encoding a subunit of the chitobiose transporter, bb0629 (fruA-2) encoding a putative carbohydrate transporter and bb0644 (nanE) encoding a putative GlcNAc-6 phosphate-2-epimerase predicted to catalyze the conversion of N-acetylmannosamine 6-phosphate (ManNAc-6-P) to GlcNAc-6-P. Quantitative RT-PCR was used to confirm differential expression of select genes, and substitution of free GlcNAc with free ManNAc resulted in growth to high cell density, suggesting B. burgdorferi cells can utilize free ManNAc for cell wall synthesis and energy production. PMID- 30285240 TI - Evaluation of Yellow Sticky Traps Baited With Citrus Scents, Coconut Oil, and Commercial Lures as a Simple Tool to Monitor Diaphorina citri (Hemiptera: Liviidae) Under Tropical Dry Forest Conditions. AB - Efficient, economic, and simple monitoring methods are important to develop successful integrated management for Asian citrus psyllid (ACP) especially in developing countries. Two 5-wk tests were carried out to study the capture of ACP adults using yellow sticky traps by adding commercial citrus fruit scents (lemon, tangerine, or orange) or commercial coconut oil (first test) and to compare these baits with commercial lures (Alpha Scents and Pest Wizard) (second test) under natural infestation conditions. In the first test, the following treatments were carried out: yellow sticky traps baited with 1) coconut oil; 2) lemon, tangerine, or orange commercial scents; or 3) unbaited yellow sticky tramps (control). In the second test, treatments were as follows: traps baited with 1) coconut oil; 2) lemon, tangerine, or orange commercial scents; 3) two different commercial lures (Pest Wizard and Alpha Scents); and 4) unbaited traps. In the first experiment, the results obtained showed that traps with a coconut oil lure captured 4.4 ACP adults per trap per week, whereas control traps caught 1 ACP adult. In the second test, coconut oil (4.5 adults per trap per week) and Alpha Scents (4.2 individuals) lures also exhibited a higher capture in comparison to all citrus scents (3.1 individuals) and Pest Wizard (3.5 individuals), and control (2 individuals). In conclusion, these results suggest that the use of commercial attractants, mainly coconut oil, can be more attractive than unbaited traps and this may be helpful for integrating into integrated pest management programs intended for ACP. PMID- 30285241 TI - Post-learning paradoxical sleep deprivation impairs reorganization of limbic and cortical networks associated with consolidation of remote contextual fear memory in mice. AB - Study Objectives: Paradoxical sleep (PS) has been shown to play an important role in memory, in particular in emotional memory processes. However, the involvement of this particular sleep stage in the systemic consolidation of remote (30 days old) memory has never been tested. We examined whether post-learning PS could play a role in the consolidation of remote fearful memory and in the brain network reorganization that depends on it. Methods: Mice were PS-deprived during 6 hours after contextual fear conditioning using an automated method, and their memory was tested either 1 day or 30 days after learning. Brain activity during retrieval was assessed using the immediate early gene Egr1 (Zif 268) as a neuronal marker of activity. Results: We found that PS deprivation impaired the recall of remote (30 days)-but not recent (1 day)-memory. We also showed that the superficial layers of the anterior cingulate cortex were significantly less activated during the retrieval of remote memory after PS deprivation. In contrast, after such deprivation, retrieval of remote memory significantly activated several areas involved in emotional processing such as the CA1 area of the ventral hippocampus, the basolateral amygdala and the superficial layers of the ventral orbitofrontal cortex. By performing graph-theoretical analyses, our result also suggests that post-learning PS deprivation could impact the reorganization of the functional connections between limbic areas in order to reduce the level of global activity in this network. Conclusions: These findings suggest an important role for PS in the systemic consolidation of remote memory. PMID- 30285239 TI - High-resolution DNA quadruplex structure containing all the A-, G-, C-, T tetrads. AB - DNA can form diverse structures, which predefine their physiological functions. Besides duplexes that carry the genetic information, quadruplexes are the most well-studied DNA structures. In addition to their important roles in recombination, replication, transcription and translation, DNA quadruplexes have also been applied as diagnostic aptamers and antidisease therapeutics. Herein we further expand the sequence and structure complexity of DNA quadruplex by presenting a high-resolution crystal structure of DNA1 (5'-AGAGAGATGGGTGCGTT-3'). This is the first quadruplex structure that contains all the internal A-, G-, C-, T-tetrads, A:T:A:T tetrads and bulged nucleotides in one single structure; as revealed by site-specific mutagenesis and biophysical studies, the central ATGGG motif plays important role in the quadruplex formation. Interestingly, our structure also provides great new insights into cation recognition, including the first-time reported Pb2+, by tetrad structures. PMID- 30285242 TI - Letter to the Editor: "Incidence of Hypoglycemia After Gastric Bypass vs Sleeve Gastrectomy: A Randomized Trial". PMID- 30285243 TI - Antibiotic treatment of gastroenteritis in primary care. AB - Background: Gastroenteritis (GE) is a frequent reason for consultating a general practitioner. Yet little is known about antibiotic prescribing in primary care patients with GE. In this study, we quantified empirical and targeted antibiotic treatment of GE, compliance with recommendations from primary care clinical practice guidelines (CPGs) and the degree of antimicrobial resistance in patients receiving diagnostic faeces testing (DFT). Methods: We performed a cohort study using routine care data of 160 general practitioners, including electronic patient records from 2013 to 2014. GE episodes were extracted and linked to microbiological laboratory records to retrieve results of DFT. For each episode, data on patient characteristics, DFT results including antimicrobial resistance testing, and antibiotic prescriptions were collected. Results: We identified 13 217 GE episodes. Antibiotic treatment was prescribed in 1163 (8.8%) episodes, most frequently with metronidazole (n = 646, 4.9%), azithromycin (n = 254, 1.9%) or ciprofloxacin (n = 184, 1.4%). Treatment was empirical for 641 (5%) GE episodes, of which 30% (n = 191) followed the CPG-recommended antibiotic choice. Targeted treatment following DFT results was prescribed for 537 GE episodes (4%), of which 99% (n = 529) followed CPG recommendations. Non-susceptibility to first- or second-choice antibiotics was demonstrated in three Salmonella isolates (9% 13% of all isolates) and one Campylobacter isolate (1%). Conclusions: Antibiotic treatment of GE in primary care is relatively infrequent, with 1 in 11 episodes treated. Empirical treatment was more frequent compared with targeted treatment and mostly with non-CPG-recommended antibiotics. However, treatment based upon DFT results followed CPG recommendations. PMID- 30285244 TI - Salivary cortisone to estimate cortisol exposure and sampling frequency required based on serum cortisol measurements. AB - Context: Population studies frequently measure cortisol as a marker of stress and excess cortisol is associated with increased mortality. Cortisol has a circadian rhythm and frequent blood sampling is impractical to assess exposure. We investigated measuring salivary cortisone and examined sampling frequency required to determine cortisol exposure. Methods: Serum and saliva with cortisol and cortisone measured by LC-MS/MS in independent cohorts. The relationship between serum cortisol and salivary cortisone was analysed in cohort 1 using a linear mixed effects model and resulting fixed effects component was applied to cohort 2. Saliva cannot easily be collected when sleeping so we determined minimum sampling required to estimate cortisol exposure (eAUC) using 24-hour cortisol profiles (AUC24) and calculated the relative error (RE - a measure similar to the coefficient of variation) for the eAUC. Results: >90% of variability in salivary cortisone could be accounted for by change in serum cortisol. A single serum cortisol measurement was a poor estimate of AUC24 especially in the morning or last thing at night (RE > 68%), however 3 equally spaced samples gave a median RE of 0% (Interquartile range (IQR) between -15.6% and 15.1%). In patients with adrenal incidentalomas the eAUC based on 3 serum cortisol samples showed a difference between those with autonomous cortisol secretion and those without (p=0.03). Interpretation: Accepting that most people sleep 7-8 hours, using approximately 8-hourly salivary cortisone measurements provides a non-invasive method of estimating 24-hour cortisol exposure for population studies. PMID- 30285245 TI - Discovery of SERPINA3 as a candidate urinary biomarker of lupus nephritis activity. AB - Objectives: We used an unbiased proteomics approach to identify candidate urine biomarkers (CUBMs) predictive of LN chronicity and pursued their validation in a larger cohort. Methods: In this cross-sectional pilot study, we selected urine collected at kidney biopsy from 20 children with varying levels of LN damage (discovery cohort) and performed proteomic analysis using isobaric tags for relative and absolute quantification (iTRAQ). We identified differentially excreted proteins based on degree of LN chronicity and sought to distinguish markers exhibiting different relative expression patterns using hierarchically clustered log10-normalized relative abundance data with linked and distinct functions by biological network analyses. For each CUBM, we performed specific ELISAs on urine from a validation cohort (n = 41) and analysis of variance to detect differences between LN chronicity, with LN activity adjustment. We evaluated for CUBM expression in LN biopsies with immunohistochemistry. Results: iTRAQ detected 112 proteins in urine from the discovery cohort, 51 quantifiable in all replicates. Simple analysis of variance revealed four differentially expressed, chronicity-correlated proteins (P-values < 0.05). Further correlation and network analyses led to selection of seven CUBMs for LN chronicity. In the validation cohort, none of the CUBMs distinguished LN chronicity degree; however, urine SERPINA3 demonstrated a moderate positive correlation with LN histological activity. Immunohistochemistry further demonstrated SERPINA3 staining in proximal tubular epithelial and endothelial cells. Conclusion: We identified SERPINA3, a known inhibitor of neutrophil cathepsin G and angiotensin II production, as a potential urine biomarker to help quantify LN activity. PMID- 30285246 TI - CRISPRlnc: a manually curated database of validated sgRNAs for lncRNAs. AB - The CRISPR/Cas9 system, as a revolutionary genome editing tool for all areas of molecular biology, provides new opportunities for research on lncRNA's function. However, designing a CRISPR/Cas9 single guide RNA (sgRNA) for lncRNA is not easy with an unwarrantable effectiveness. Thus, it is worthy of collecting validated sgRNAs, to assist in efficiently choosing sgRNA with an expected activity. CRISPRlnc (http://www.crisprlnc.org or http://crisprlnc.xtbg.ac.cn) is a manually curated database of validated CRISPR/Cas9 sgRNAs for lncRNAs from all species. After manually reviewing more than 200 published literature, the current version of CRISPRlnc contains 305 lncRNAs and 2102 validated sgRNAs across eight species, including mammalian, insect and plant. We handled the ID, position in the genome, sequence and functional description of these lncRNAs, as well as the sequence, protoacceptor-motif (PAM), CRISPR type and validity of their paired sgRNAs. In CRISPRlnc, we provided the tools for browsing, searching and downloading data, as well as online BLAST service and genome browse server. As the first database against the validated sgRNAs of lncRNAs, CRISPRlnc will provide a new and powerful platform to promote CRISPR/Cas9 applications for future functional studies of lncRNAs. PMID- 30285247 TI - Mosquito (Diptera: Culicidae) Species Composition in Ovitraps From a Mesoamerican Tropical Montane Cloud Forest. AB - Knowledge about mosquito species diversity at tropical montane cloud forests (TMCFs) in Mesoamerica is scarce. Here, we present data on mosquito species richness from samples biweekly collected, from January to December 2017, in ovitraps installed in a TMCF patch at Vazquez de Coronado County, Costa Rica. Ovitraps were placed at 2.25, 1.50 and 0.75 m at 16 sampling points. During the study period we measured relative humidity and air temperature at each sampling point, and water temperature, volume and pH in each ovitrap. We collected a total of 431 mosquito larvae belonging to five taxonomic units, one identified to the genus level and four to the species level. The most common mosquito species was Culex bihaicolus Dyar & Nunez Tovar (Diptera: Culicidae), which accounted for nearly 80% (n = 344) of the collected mosquitoes. Culex nigripalpus Theobald (Diptera: Culicidae) was the only medically important species we found and it was collected both in the dry (January to March) and rainy season (April to December). Over 95% (n = 411) of the mosquitoes were collected during the rainy season and 60% (n = 257) at 0.75 m. Among the environmental variables that we measured, only water volume and pH were significantly (P < 0.05) different between the dry and rainy season, the former increasing and the later decreasing during the rainy season. These results suggest that rainfall plays a major role regulating the phenology of the sampled mosquito species and highlight the need to screen for pathogens in Cx. nigripalpus at the study area. PMID- 30285248 TI - Daily Links Between Sleep and Anger Among Spouses of Chronic Pain Patients. AB - Objectives: This study identified daily associations between sleep, emotion, and marital functioning in the context of chronic pain. Because spouses' sleep is compromised on nights when patients experience more pain, we set out to identify implications of spouses' sleep for their own emotion (anger) upon waking and marital interaction (marital tension) throughout the rest of the day. We further considered whether spouses' critical attitudes about patients' pain-related coping exacerbated associations between their sleep, morning anger, and marital tension. Method: Data came from a study of knee osteoarthritis patients (50+ years old) and spouses (N = 138 couples) who completed daily diaries across 22 days. Multilevel models were estimated to test hypotheses. Results: Spouses woke up angrier on mornings when they reported that their sleep was more unrefreshing than usual. This association was stronger among more critical spouses. Morning anger resulting from unrefreshing sleep, however, did not predict marital tension throughout the rest of the day. Discussion: Findings highlight the potential value of intervention efforts aimed at promoting spouses' sleep quality in an effort to offset negative emotional consequences that may undermine spouses' and patients' adjustment in the context of chronic pain. PMID- 30285249 TI - Important candidate genes for abdominal fat content identified by linkage disequilibrium and fixation index information. AB - Selection for rapid growth in chickens has always been accompanied by increased fat deposition and excessive fat deposition, especially abdominal fat, cannot only decrease feed efficiency but also cause many diseases. Finding the candidate genes associated with abdominal fat deposition is essential for breeding. To identify these candidate genes, we applied linkage disequilibrium and selection signature analysis using chicken 60 k single nucleotide polymorphism (SNP) chips in two broiler lines divergently selected for abdominal fat content for 11 generations. After quality control, 46,033 SNPs were left for analysis. Using these SNPs, we found that r2 was 0.06 to 0.14 in the lean line and 0.07 to 0.13 in the fat line for all 28 chromosomes (except GGA16). Pairwise SNP distances <25 kb showed a mean r2 = 0.33 in the lean line and r2 = 0.32 in the fat line. The fixation index (FST) analysis was carried out and 46 SNPs with the top 0.1% of the FST value was detected as the loci with selection signatures. Besides FST, hapFLK was also used to detect selection signatures for abdominal fat content. A total of 11 genes, including transient receptor potential cation channel subfamily C member 4, estrogen related receptor gamma, fibroblast growth factor 13, G-protein-signaling modulator 2, RAR related orphan receptor A, phospholipase A2 group X, mitochondrial ribosomal protein L28, metadherin, calcitonin receptor like receptor, serine/threonine kinase 39, and nuclear factor I A, were detected as the important candidate genes for abdominal fat deposition based on their basic functions. The results of the present study may benefit the understanding of genetic mechanism of abdominal fat deposition in chicken. PMID- 30285251 TI - Effect of vitamin E in ovo feeding to broiler embryos on hatchability, chick quality, oxidative state, and performance. AB - The objective of the present study was to ascertain the effect of in ovo feeding of vitamin E (VE) on the incubation results, quality, and oxidative state of newborn chicks and on the initial performance results. The design consisted of randomized blocks with treatments at different levels of VE (0.0, 27.5, 38.5, 49.5, and 60.4 IU). On 17.5 d of embryonic development, 780 eggs underwent in ovo injection using a manual needle. VE supplementation of 60.4 IU provided the highest hatching rate (P < 0.05) and shortest hatch window (P < 0.05). Better results regarding chick physical quality were observed in groups supplemented with VE (body weight, length, newborn chick quality score) and higher chick weight/egg weight ratios (P < 0.05). VE inoculation did not have any effect on the chicks' immunological system (P > 0.05). Greater development of the small intestine (intestine weight/yolk free chick weight and higher villi in duodenum) and better feed conversion over all periods studied (1 to 7, 1 to 14, and 1 to 21 d) were observed among chicks that received in ovo VE supplementation (P < 0.05). The total protein concentrations in the liver and striated breast skeletal muscle tissue were highest in chicks that received 60.4 IU of VE (P < 0.05). The highest catalase activity was observed in the livers of newborn chicks supplemented with 60.4 IU of VE (P < 0.05). It was concluded that in ovo VE supplementation improved the chicks' oxidative state, which led to improvements in incubation results, chick quality and performance results. PMID- 30285250 TI - Cross-sectional associations of objectively-measured sleep characteristics with obesity and type 2 diabetes in the PREDIMED-Plus trial. AB - Study Objectives: To examine independent and combined associations of sleep duration and sleep variability with body composition, obesity and type 2 diabetes (T2D) in elders at high cardiovascular risk. Methods: Cross-sectional analysis of 1986 community-dwelling elders with overweight/obesity and metabolic syndrome from PREDIMED-Plus trial. Associations of accelerometry-derived sleep duration and sleep variability with body mass index (BMI), waist circumference (WC) and body composition were assessed fitting multivariable-adjusted linear regression models. Prevalence ratios (PR) and 95% confidence intervals (CI) for obesity and T2D were obtained using multivariable-adjusted Cox regression with constant time. "Bad sleepers" (age-specific non-recommended sleep duration plus sleep variability above the median) and "good sleepers" (age-specific recommended sleep duration plus sleep variability below the median) were characterized by combining sleep duration and sleep variability, and their associations with these outcomes were examined. Results: One hour/night increment in sleep duration was inversely associated with BMI (beta -0.38 kg/m 2 [95% CI -0.54, -0.23]), WC (beta -0.86 cm [95% CI -1.25, -0.47]), obesity (PR 0.96 [95% CI 0.93, 0.98]), T2D (PR 0.93 [95% CI 0.88, 0.98]) and other DXA-derived adiposity-related measurements (android fat and trunk fat, all p < .05). Each 1-hour increment in sleep variability was positively associated with T2D (PR 1.14 [95% CI 1.01, 1.28]). Compared with "good sleepers," "bad sleepers" were positively associated with obesity (PR 1.12 [95% CI 1.01, 1.24]) and T2D (PR 1.62 [95% CI 1.28, 2.06]). Conclusions: This study revealed cross-sectional associations of sleep duration with adiposity parameters and obesity. Sleep duration and sleep variability were associated with T2D. Considering simultaneously sleep duration and sleep variability could have additional value, particularly for T2D, as they may act synergistically. PMID- 30285252 TI - Developing a Pain Intensity Measure for Persons with Dementia: Initial Construction and Testing. AB - Objective: The goal of this study was to identify a limited set of pain indicators that were most predicive of physical pain. We began with 140 items culled from existing pain observation tools and used a modified Delphi approach followed by statistical analyses to reduce the item pool. Methods: Through the Delphi Method, we created a candidate item set of behavioral indicators. Next, trained staff observed nursing home residents and rated the items on scales of behavior intensity and frequency. We evaluated associations among the items and expert clinicians' assessment of pain intensity. Setting: Four government-owned nursing homes and 12 community nursing homes in Alabama and Southeastern Pennsylvania. Participants: Ninety-five residents (mean age = 84.9 years) with moderate to severe cognitive impairment. Results: Using the least absolute shrinkage and selection operator model, we identified seven items that best predicted clinicians' evaluations of pain intensity. These items were rigid/stiff body or body parts, bracing, complaining, expressive eyes, grimacing, frowning, and sighing. We also found that a model based on ratings of frequency of behaviors did not have better predictive ability than a model based on ratings of intensity of behaviors. Conclusions: We used two complementary approaches-expert opinion and statistical analysis-to reduce a large pool of behavioral indicators to a parsimonious set of items to predict pain intensity in persons with dementia. Future studies are needed to examine the psychometric properties of this scale, which is called the Pain Intensity Measure for Persons with Dementia. PMID- 30285253 TI - Comparison of performance and feed digestibility of the non-antibiotic feed supplement (Novacid) and an antibiotic growth promoter in broiler chickens. AB - Antibiotic growth promoters have been widely used in poultry to improve overall performance. The emergence of antibiotic resistance has resulted in sanctions imposed on the use of antibiotics in poultry diets, and alternatives such as herbal extracts are being considered to improve growth performance. The aim of this study was to compare the performance and feed digestibility of the feed supplement Novacid, which contains organic acids, glucomannan, and phytochemicals, with that of the antibiotic growth promoter bacitracin methylene disalicylate (BMD) in commercial broiler chickens. Six hundred 1-d-old Ross * Ross 308 male broiler chicks were randomly and equally assigned to six treatment groups with five replicates each (20 chicks per replicate). The chicks were fed a corn-soybean meal basal diet, and divided into two groups: unchallenged and challenged with E. coli (400 mg/kg Escherichia coli inoculation). Each of these groups was divided into three study groups: untreated, treated with 0.05% Novacid, and treated with 400 mg/kg BMD. At day 42, inclusion of Novacid or BMD significantly (P < 0.05) improved the performance in the unchallenged groups relative to the control group. However, in E. coli-challenged groups, Novacid and BMD did not improve performance. Ileal digestibility of crude fat, crude protein, and gross energy were reduced in the Novacid group (P < 0.05). BMD and Novacid were equally effective in controlling ileal nutrient digestibility and feed coliform count (P < 0.05). Novacid reduced cecal E. coli and Salmonella count compared to BMD and control. Thus, a phytochemical feed supplement with organic acids and glucomannan could be an effective substitute for antibiotic growth promoters in broiler diets, but cannot replace antibiotics to counter potent infectious agents such as E. coli.

PMID- 30285255 TI - Altered Global Signal Topography and Its Different Regional Localization in Motor Cortex and Hippocampus in Mania and Depression. AB - Bipolar disorder (BD) is a complex psychiatric disorder characterized by dominant symptom swings across different phases (manic, depressive, and euthymic). Different symptoms in BD such as abnormal episodic memory recall and psychomotor activity have been related to alterations in different regions, ie, hippocampus and motor cortex. How the abnormal regional distribution of neuronal activity relates to specific symptoms remains unclear, however. One possible neuronal mechanism of the relationship is the alteration of the global distribution of neuronal activity manifested in specific local regions; this can be measured as the correlation between the global signal (GS) and local regions. To understand the GS and its relationship to psychopathological symptoms, we here investigated the alteration of both GS variance and its regional topography in healthy controls and 3 phases of BD. We found that the variance of GS showed no significant difference between the 4 groups. In contrast, the GS topography was significantly altered in the different phases of BD, ie, the regions showing abnormally strong topographical GS contribution changed from hippocampus (and parahippocampus/fusiform gyrus) in depression to motor cortex in mania. Importantly, topographical GS changes in these regions correlated with psychopathological measures in both depression and mania. Taken together, our findings demonstrate the central importance of GS topography for psychopathological symptoms. This sheds lights on the neuronal mechanisms of specific psychopathological symptoms in BD, and its relevance in the relationship between global and local neuronal activities for behavior in general.

PMID- 30285257 TI - Food Consumption, Developmental Time, and Protein Profile of the Digestive System of the Red Palm Weevil, Rhynchophorus ferrugineus (Coleptera: Dryophthoridae) Larvae Reared on Three Different Diets. AB - The red palm weevil (RPW), Rhynchophorus ferrugineus Olivier (Coleoptera: Dryophthoridae) is one of the most dangerous pests of major cultivated palms including coconut, oil palm, and sago. The larval stage of the weevil causes the most destruction of the palms as it completely destroys the palm cabbage. In this study, the larvae were given three different diets-coconut cabbage, oil palm cabbage, and sago stem, under laboratory conditions for food consumption and developmental time experiment. The protein profiles of the digestive systems of the larvae fed on these three diets were also determined. Although the coconut diet was the most consumed by RPW larvae compared to oil palm and sago diets, the growth rate of RPW larvae on oil palm diet was however significantly shorter than those on the coconut and sago diets: the RPW only need 1 mo and 9 d to complete the larval duration. Proteins profiling of eight 2-DE gel protein spots that range 50-20 kDa were identified by mass spectrometry sequence analysis. Based on the Matrix Science Software, the most dominant protein was cationic trypsin. However, based on the NCBI BLAST tool, aminopeptidase N was the most dominant enzyme. This finding can lead to the development of pest control strategies based on the antinutritional protease inhibitors as potential biocontrol agents. Urgent action to find effective control methods should be taken seriously as this weevil is presumed to be one of the serious pests of oil palm industry in Malaysia.

AB - The objective of this experiment was to study the effects of dietary zinc (Zn) source on gene expression of Zn transporters (metallothionein [MT], ZIP 3, 5, 8, 9, 10, 11, 13, and 14, and ZnT 1, 4, 5, 6, 7, 9, and 10) in the jejunum and cecal tonsils of broilers challenged with coccidia or coccidia plus Clostridium perfringens. A 2 * 2 factorial design was used with 2 Zn sources (90 mg Zn/kg from either ZnSO4 or an organic Zn, Bioplex(r) Zn) and challenged with approximately 5,000 oocysts of Eimeria maxima at 14 d of age with or without C. perfringens (108 CFU/bird) at 18, 19, and 20 d of age (8 pens per treatment and 8 birds per pen) after which 1 bird/pen was sampled at 21 d of age. In the jejunum, co-infection resulted in higher ZnT 5 and 6 gene expression, while organic Zn fed birds had lower ZIP 5 and 11, and higher ZnT1. Additionally, an interaction of challenge by Zn source was noted wherein ZnT10 was unaffected by the C. perfringens in the organic Zn treatment but was 2.7-fold lower in the co-infected ZnSO4 fed birds. S100A9 gene expression, a biomarker of inflammatory response in necrotic enteritis, increased 2 and 2.8-fold in the cecal tonsils and jejunum with the co-infection, respectively. Supplementation with organic Zn lowered S100A9 by 1.9 and 4.4-fold in the cecal tonsils and jejunum, respectively, when birds were supplemented with ZnSO4. Notably, MT, ZIP 3, 8, 9, 10, 13, or 14, and ZnT 4, 7, and 9 were unaffected by Zn source and/or method of challenge. An interaction of challenge by Zn source was also noted for serum Zn concentration, which was reduced when birds were challenged with C. perfringens and fed ZnSO4 but no difference between challenge method when birds were fed organic Zn. Based on the expression of ZnT and ZIP genes, more Zn trafficking due to treatment occured in the jejunum than cecal tonsils, but further studies are needed to ascertain how Zn source regulates intracellular free Zn concentrations and whole body Zn status during an enteric challenge. PMID- 30285258 TI - Transcriptomics-Based Identification of Aquaporin Diversity in the House Dust Mite Dermatophagoides farinae (Acariformes: Pyroglyphidae). AB - Aquaporin water channel proteins are highly conserved across many diverse species. Some evidence indicates that aquaporins in insects may contribute to insect-related mammalian diseases and inflammation, and thus these proteins may represent viable therapeutic targets. Here, we used RNA sequencing and bioinformatics to identify putative aquaporins from the house dust mite, Dermatophagoides farinae. Six putative aquaporins were identified based on sequence similarity with aquaporins from other species. These putative aquaporins, deposited in GenBank and named DerfAQP1-4 (KY231248, KY231249, KY231250, and KY231251, respectively), DerfAQP5.01, and DerfAQP5.02 (KY231252 and KY231253), were successfully cloned into a bacterial plasmid. The identification of full-length aquaporin sequences from D. farinae provides a foundation for future molecular and biochemical studies of these proteins in D. farinae and related species. PMID- 30285261 TI - Provision of Buprenorphine to Pregnant Women by For-Profit Clinics in an Appalachian City. AB - OBJECTIVES: This study was undertaken to confirm that patient reports on buprenorphine medication-assisted therapy in for-profit buprenorphine clinics in our community were personally costly. We contacted all 17 for-profit clinics in our community and confirmed the patient reports that a significant financial payment of <=$100 was required for each visit. We also found that tapering of buprenorphine dosage in pregnancy was offered by several of the clinics. METHODS: A telephone survey was conducted with the 17 for-profit buprenorphine clinics located in the Johnson City, Tennessee area. The clinic representative who answered the telephone was asked questions regarding patient costs for therapy and availability of tapering programs for pregnant women. RESULTS: Patient reports that the for-profit clinics are costly were confirmed. None of the clinics accepted insurance reimbursement of any type. The most common weekly costs were $100 per visit. A majority of clinics offered biweekly or monthly visits at significantly increased rates. Clinic representatives stated that a majority of clinics would consider buprenorphine tapering programs for pregnant women. CONCLUSIONS: The high cost of for-profit clinics is a barrier for patient access to medication-assisted therapy with buprenorphine. Tapering of buprenorphine dosage in pregnant women has penetrated buprenorphine management practice in our community. Further research is needed to determine whether elimination of cost barrier would have a positive effect on the rates of neonatal abstinence syndrome. PMID- 30285260 TI - Genome-Wide Association Study Detected Novel Susceptibility Genes for Schizophrenia and Shared Trans-Populations/Diseases Genetic Effect. AB - Genome-wide association studies (GWASs) have identified >100 susceptibility loci for schizophrenia (SCZ) and demonstrated that SCZ is a polygenic disorder determined by numerous genetic variants but with small effect size. We conducted a GWAS in the Japanese (JPN) population (a) to detect novel SCZ-susceptibility genes and (b) to examine the shared genetic risk of SCZ across (East Asian [EAS] and European [EUR]) populations and/or that of trans-diseases (SCZ, bipolar disorder [BD], and major depressive disorder [MDD]) within EAS and between EAS and EUR (trans-diseases/populations). Among the discovery GWAS subjects (JPN-SCZ GWAS: 1940 SCZ cases and 7408 controls) and replication dataset (4071 SCZ cases and 54479 controls), both comprising JPN populations, 3 novel susceptibility loci for SCZ were identified: SPHKAP (Pbest = 4.1 * 10-10), SLC38A3 (Pbest = 5.7 * 10 10), and CABP1-ACADS (Pbest = 9.8 * 10-9). Subsequent meta-analysis between our samples and those of the Psychiatric GWAS Consortium (PGC; EUR samples) and another study detected 12 additional susceptibility loci. Polygenic risk score (PRS) prediction revealed a shared genetic risk of SCZ across populations (Pbest = 4.0 * 10-11) and between SCZ and BD in the JPN population (P ~ 10-40); however, a lower variance-explained was noted between JPN-SCZ GWAS and PGC-BD or MDD within/across populations. Genetic correlation analysis supported the PRS results; the genetic correlation between JPN-SCZ and PGC-SCZ was rho = 0.58, whereas a similar/lower correlation was observed between the trans-diseases (JPN SCZ vs JPN-BD/EAS-MDD, rg = 0.56/0.29) or trans-diseases/populations (JPN-SCZ vs PGC-BD/MDD, rho = 0.38/0.12). In conclusion, (a) Fifteen novel loci are possible susceptibility genes for SCZ and (b) SCZ "risk" effect is shared with other psychiatric disorders even across populations. PMID- 30285262 TI - Birth Weight and Risk of Childhood Acute Lymphoblastic Leukemia in Arizona, Illinois, and Kentucky. AB - OBJECTIVE: To confirm the previously reported increased risk of leukemia among macrosomic children (those with birth weight >4 kg). METHODS: Birth certificates of Arizona, Illinois, and Kentucky children diagnosed as having acute lymphoblastic leukemia (ALL) before age 5 years were matched with birth certificates from leukemia-free children of the same sex, race, and ethnicity who were born in the same county on or about the same day. Odds ratios (ORs) for ALL among children of low (<2.5 kg) or high (>4 kg) birth weight were calculated by conditional logistic regression. RESULTS: Children with high birth weight had an elevated risk of ALL in the first 5 years of life (OR 1.28, 95% confidence interval [CI] 1.01-1.61). The excess risk was confined to non-Hispanic whites (OR 1.77, 95% CI 1.27-2.48), both boys (OR 1.57, 95% CI 1.01-2.45) and girls (OR 2.10, 95% CI 1.26-3.52). CONCLUSIONS: This study confirms the association between high birth weight and ALL previously reported by other studies in children of European ancestry. The literature on maternal risk factors for both macrosomia and ALL is reviewed, with maternal overnutrition emerging as a plausible risk factor for both outcomes. PMID- 30285263 TI - Contemporary Geographic Variation and Sociodemographic Correlates of Hysterectomy Rates Among Reproductive-Age Women. AB - OBJECTIVE: For decades hysterectomy rates have famously demonstrated unexplained geographic variation. The aim of this study was to identify county-level correlates of hysterectomy rates among reproductive-age women. METHODS: Using county-level data from multiple sources, linked with claims-based surveillance data of every hysterectomy performed among women ages 20 to 44 in North Carolina from 2011 to 2013 (N = 7180), we explored social, economic, and healthcare factors associated with county-level rates. RESULTS: After accounting for spatial autocorrelation, county-level hysterectomy rates were negatively associated with county-level median household income, positively associated with the proportion married, and not associated with measures of healthcare capacity or access. CONCLUSIONS: This analysis provides preliminary evidence that contemporary hysterectomy use in North Carolina occurs along socioeconomic lines. PMID- 30285264 TI - Effects of Maternal Carbohydrate and Fat Intake on Fetal Telomere Length. AB - OBJECTIVES: Telomere length can be affected by dietary factors in adults. We investigated the association between maternal carbohydrate and fat intake during pregnancy and telomere length in neonatal cord blood leukocytes. We hypothesized that high fat consumption and high carbohydrate consumption would be associated with shortened fetal telomere length. METHODS: We collected umbilical cord blood at delivery from women admitted for labor and delivery in a university hospital (N = 62) and extracted genomic DNA using quantitative polymerase chain reaction. We quantified telomere length using the telomere-to-single copy gene ratio method (T:S ratio). High carbohydrate intake was defined as consumption of >175 g/day and high fat intake as >35 g/day. We performed generalized linear regression modeling and bootstrap statistical analyses to derive precise estimates of association. RESULTS: Of the 62 maternal-fetal dyads included in this study, 79% were classified as high carbohydrate consumers and 37% were classified as high fat consumers. High fat consumption had a significant negative effect on T:S ratio (P < 0.05). Although high carbohydrate consumption was associated with a decreased T:S ratio, this relation did not attain statistical significance. CONCLUSIONS: To our knowledge, this study is the first evidence of an association between maternal high fat consumption and shortened fetal telomere length. These findings could enhance our understanding of the role of maternal diet in fetal programming. PMID- 30285265 TI - Expenditures and Quality: Hospital- and Health System-Affiliated Versus Independent Physicians in Virginia. AB - OBJECTIVES: The American Medical Association has reported that 2016 was the first year in which fewer than half (47.1%) of all practicing physicians owned their own practice. Across the United States, there has been consolidation of physicians and hospital and health systems, resulting in questions about the effect of this on healthcare expenditures. The aim of this study was to compare the expenditures per patient between hospital- and health system-affiliated physicians and independent physicians. METHODS: The author used Virginia's new statewide all-payer claims database to analyze expenditures and quality for 3 years for hospital- and health system-affiliated physicians versus independent physicians. The database had all claims statewide for Virginians with individual or group commercial insurance coverage: 1.95 million patients in 2013, 2 million in 2014, and 2.1 million in 2015. The average annual expenditure for each physician was adjusted for average patient condition burden (risk) and differences in geographic input costs using regression analysis. Measures of primary care quality were obtained from the claims data using evidence-based measures from national health quality organizations. RESULTS: Hospital- and health system-affiliated physicians had annual expenditures per patient ranging from 10.3% to 14.6% higher than independent physicians. Most of the measures of primary care quality were not significantly different. CONCLUSIONS: Virginia patients, employers, and managed care companies incurred higher per-patient expenditures with hospital and health system physicians than with independent physicians. PMID- 30285266 TI - Protocol to Improve Genotyping of Non-Small-Cell Lung Cancer Diagnosed Using EBUS TBNA. AB - OBJECTIVES: Targeted therapies for non-small-cell lung cancers (NSCLCs) are based on the presence of driver mutations such as epidermal growth factor receptor (EGFR) and the echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) translocation. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a first-line modality for diagnosing and staging NSCLC. A quality improvement protocol maximizing tissue acquisition for molecular analysis has not been previously described. METHODS: We instituted a standardized protocol designed from a multidisciplinary meeting of the pulmonology, oncology, and pathology departments for the acquisition and on site processing of samples obtained through EBUS-TBNA to improve the yield for genetic analysis of EGFR and ALK testing. RESULTS: Preprotocol there were 50 NSCLCs (29 adenocarcinomas) and postprotocol there were 109 NSCLCs (52 adenocarcinomas). A statistically significant increase in yield for molecular analysis was seen in both EGFR (36% preprotocol and 80% postprotocol, P < 0.01) and ALK (41% preprotocol and 80% postprotocol, P < 0.01). There was no difference in complications preprotocol and postprotocol. CONCLUSIONS: Implementation of a standardized protocol with EBUS-TBNA was associated with an increase in adequacy for molecular genetic analysis in NSCLC. PMID- 30285267 TI - Homicide in the South: Higher Rates Among Whites and Fewer Racial Disparities. AB - OBJECTIVE: Describe southern US homicide rates in whites and blacks between 1999 and 2015. METHODS: The Centers for Disease Control and Prevention Multiple Cause of Death Files provided mortality rates and 95% confidence intervals (CIs) for non-Hispanic whites (NHW) as well as non-Hispanic blacks and African Americans (NHB). RESULTS: Overall, age-adjusted (1 to >=85 years) homicide was significantly higher in the South (7.6/100,000, 95% CI 7.6-7.7) than the rest of the United States (4.9/100,000, 95% CI 4.8-4.9) even though the southern rate among NHB (18.7/100,000, 95% CI 18.5-18.8) was lower than the rest of the United States (23.3/100,000, 95% CI 23.1-23.5). The overall southern NHB:NHW mortality rate ratio was 5.1 and 10.6 in the rest of the nation. Homicide rates among NHW men were higher in the South than in each of the other US Census areas, whereas corresponding rates among NHB men were lower. For both men and women the NHB:NHW mortality rate ratio was lower in the South than in any other region. In addition, homicide rates among NHB women in the South were equal to or lower than corresponding rates in the West and Midwest. Finally, higher rates for NHW in metropolitan areas led to overall higher NHW mortality rates and relatively low NHB:NHW rates. Southern NHW had a higher percentage of firearms-related homicides (58.4%) than the corresponding percentage in the rest of the United States (49.8%; P < 0.001). Southern NHB used firearms for 78.8% of homicides compared with 83.9% in the rest of the United States (P < 0.001). CONCLUSIONS: The overall high homicide rates in the southern United States were attributable to relatively higher NHW rates than those found in the rest of the country. Further research targeting the role of firearms as well as cultural and other issues could further the understanding of the interrelations of homicide with complex regional and cultural factors. PMID- 30285268 TI - Effects of Religious Involvement on HIV Management Outcomes Among HIV-Positive Adults in Central North Carolina. AB - OBJECTIVES: The goals of this pilot cross-sectional study were to determine the feasibility of and begin measuring the effect of religious institution affiliation on human immunodeficiency virus (HIV) clinical outcomes in the southern United States, a region marked by later initiation of antiretroviral therapy, higher HIV-related morbidity, and higher mortality rates than people living with HIV (PLWH) elsewhere in the country. It also is a region with a high density of religious institutions, which may facilitate improved health outcomes through leveraged social capital. Because spirituality is a personal construct and PLWH constitute a vulnerable population, we wanted to determine whether it would be feasible to survey patients about the topic. We hypothesized that PLWH would be willing to participate and that PLWH who report involvement in religious institutions would be more likely to have suppressed HIV viral loads (VLs) and better engagement in care than PLWH not involved in a religious institution. METHODS: Eligible participants were enrolled from the Wake Forest Infectious Diseases Specialty Clinic to complete structured interviews using validated measures of religious institution affiliation, spiritual well-being, social support, and HIV-related stigma. HIV VL and engagement in care (clinic no-show rate) data were abstracted from the electronic medical record. Descriptive statistics calculated the prevalence of religious institution involvement, outcomes of interest, and potential confounders. t Tests compared continuous outcomes assuming normality, chi2 tests compared binary outcomes, and the Wilcoxon Mann-Whitney test compared outcomes for non-normal data. RESULTS: Fifty participants completed the study (55% participation rate); 72% identified as male and 28% identified as female. A total of 48% of participants identified as black/African American and 44% identified as white. Participants who identified as men who have sex with men made up 34%. More black/African American participants than white participants reported religious institution affiliation (23%; P = 0.15). There was no statistically significant relation between religious institution affiliation and CD4 or VL; however, higher levels of social support and spiritual well-being predicted a lower clinic no-show rate (P = 0.0077 and 0.0195, respectively). There was a trend toward greater perceived HIV related stigma and CD4 (P = 0.0845) as well as more emergency department visits (P = 0.0976). CONCLUSION: PLWH in a southern US clinic were willing to answer questions about their spirituality. Religious institution affiliation was not significantly related to virologic suppression or CD4 in this sample. Higher levels of self-reported social support (P = 0.0077) and spiritual well-being (P = 0.0195) predict better clinic attendance. These results suggest that religious affiliation alone does not imply positive benefits for all. Social support and spiritual well-being, however obtained, predict engagement in care. The next steps should include a fully powered study to define the relations among social support, spiritual well-being, and relevant clinical outcomes. Our results also support further investigation of perceived HIV-related stigma and healthcare utilization, based on the trend toward significance between emergency department visits and stigma. PMID- 30285269 TI - Group Battlefield Acupuncture in Primary Care for Veterans with Pain. AB - OBJECTIVE: To obtain preliminary data on the short- and intermediate-term effects of battlefield acupuncture (BFA) on self-reported pain intensity in a relatively large cohort of veterans to assess whether a more comprehensive clinical trial evaluation is warranted. METHODS: The treatment, in an outpatient group setting, consisted of up to five auricular semipermanent needles inserted into each ear at prespecified points. Efficacy of treatment was measured by self-reported pain, using the Defense and Veterans Pain Rating Scale, just before treatment and at posttreatment days 0, 1, 7, and 30. RESULTS: A total of 112 patients attended the group clinics. The mean pretreatment pain score was 6.8, with an immediate postprocedure decrease of 2.4 points. The proportion of patients reporting decreased pain was 88.4%, 80.7%, 52.4%, and 51% at posttreatment days 0, 1, 7, and 30, respectively. CONCLUSIONS: The short- and intermediate-term beneficial effect of BFA on chronic pain is clinically meaningful. The large proportion of patients reporting decreased pain even 30 days after treatment suggests that the long-term effect of BFA merits further investigation. PMID- 30285270 TI - Mobile Health (mHealth) Use or Non-Use by Residents of West Virginia. AB - OBJECTIVE: To compare mobile health (mHealth) usage by residents of West Virginia with national estimates. METHODS: Pew Research Center data from its Internet and American Life Project were accessed for secondary data analysis. These data, available to the public, are a probability sample of Internet use in the United States, differences in use based on selected variables (eg, education, household income), and how usage affects the lives of Americans. Using SAS software, diagnostics were performed on the data, revealing that the variables of interest were prepared and represented without any need for information. Data were used as is, with categorical and continuous characteristics and stipulations being provided in accompanying documents from the Pew Research Center. RESULTS: The national sample consisted of 509 men and 557 women with an average age of 51.02 years (standard deviation 17.04). The 30 West Virginia residents included 19 women and 11 men (mean for age 48.10, standard deviation 15.30). When controlling for socioeconomic and demographics factors, the odds of a West Virginia resident using an mHealth device were 82% less than the rest of the country, a statistically significant association. Women in West Virginia were 52% more likely to access mHealth information than men, and an increase in age corresponded with increased mHealth usage. CONCLUSIONS: The lack of mHealth use by residents in West Virginia represents an opportunity for clinicians and scientists. The high rates of preventable diseases in the region could be more effectively managed with greater use of these technologies. PMID- 30285271 TI - Risk, Outcomes, and Predictors of Clostridium difficile Infection in Lymphoma: A Nationwide Study. AB - OBJECTIVE: The risk of Clostridium difficile infection (CDI) has not been well studied in patients with lymphoma. We thus sought to determine the risk of CDI in hospitalizations with lymphoma along with its trend, outcomes, and predictors using a large database. METHODS: Hospital discharge data from the Nationwide Inpatient Sample (NIS) from 2007 to 2011 were used for the study. Using the International Classification of Diseases, Ninth Revision, Clinical Modification codes, all adult patients aged 18 years or older having a primary diagnosis of lymphoma were queried for the presence of CDI as any of the secondary diagnoses. The risk of CDI in lymphoma and its yearly trend were assessed. We performed multivariate logistic regression to determine the independent risk factors of CDI in lymphoma. Furthermore, we studied mortality and other adverse outcomes of CDI in patients with lymphoma. RESULTS: There were 236,312 discharges (weighted) with the primary diagnosis of lymphoma. CDI was present in 2.13% of patients with lymphoma versus 0.8% in the nonlymphoma group (P < 0.001). On multivariate analysis, the significant predictors of CDI in lymphoma were presence of infection (odds ratio [OR] 3.1, 95% confidence interval [CI] 2.7-3.6), stem cell transplant (OR 2.7, 95% CI 2.3-3.4), graft-versus-host disease (OR 1.9, 95% CI 1.4-2.8), race (Asian vs white, OR 1.6, 95% CI 1.1-2.4), chemotherapy (OR 1.6, 95% CI 1.4-1.8), gastrointestinal surgery (OR 1.4, 95% CI 1.2-1.7), and Charlson Comorbidity Index (CCI) (CCI of 2 vs 0-1: OR 1.2, 95% CI 1.1-1.4; CCI of 3 vs 0 1: OR 1.3, 95% CI 1.03-1.6). CDI in lymphoma was associated with worse hospital outcomes such as increased mortality (17% vs 8%), increased length of stay (23.6 vs 9.9 days), mean total hospital charges ($197,015 vs $79,392), rate of intubation (13% vs 4% vs 13%), and rate of total parenteral nutrition (11% vs 3%). CONCLUSIONS: Hospitalization with lymphoma was associated with an increased risk of CDI. The significant predictors for CDI in lymphoma were infection, stem cell transplant, graft-versus-host disease, race, chemotherapy, gastrointestinal surgery, and Charlson Comorbidity Index. CDI in lymphoma was associated with increased mortality and other adverse outcomes warranting a need of more vigilance for CDI in patients with lymphoma.

PMID- 30285275 TI - A Comprehensive Overview of the Clinical Pharmacokinetics of Clobazam. AB - Clobazam (CLB) is a 1,5-benzodiazepine that has been widely used as an anxiolytic and antiseizure drug (ASD) since it was first synthesized over 50 years ago. CLB was approved in the United States in 2011 as adjunctive therapy for seizures in patients >=2 years old with Lennox-Gastaut syndrome. CLB pharmacokinetics (PK) have been studied in single- and multiple-dose administrations in healthy subjects. Salient features include high bioavailability, linear PK, and negligible effects from coadministration of other ASDs. CLB is highly and extensively absorbed, with little effect from food; time to maximum plasma concentration is 0.5 to 4 hours following the dose. After CLB doses of 20 to 40 mg/day, the volume of distribution is 99 to 120 L, with oral clearance ranging from 1.9 to 2.3 L/h. CLB is lipophilic and distributes throughout the body after oral administration. It is metabolized in the liver by cytochrome P450 (CYP) isoenzymes CYP3A, CYP2C19, and CYP2B6, and its main active metabolite is N desmethylclobazam. The half-life of CLB after a single oral dose ranges from 36 to 42 hours; the half-life of N-desmethylclobazam ranges from 59 to 74 hours. The metabolites of CLB are primarily excreted renally. Population PK modeling using data from healthy subjects and patients with Lennox-Gastaut syndrome indicates that race, sex, age, weight, and renal function do not influence CLB PK. As CLB has been extensively studied since the 1970s, this review is meant to provide a consolidated and comprehensive resource on CLB PK for both prescribers and scientists alike. PMID- 30285276 TI - Dabigatran as a Treatment Option for Heparin-Induced Thrombocytopenia. AB - Heparin-induced thrombocytopenia (HIT) is a potentially serious adverse drug reaction that can result in lethal vascular thrombosis. Dabigatran is a direct thrombin inhibitor that might be useful in the management of HIT. This study evaluated the efficacy and safety of dabigatran in patients with HIT. We included 43 patients in the study who received dabigatran for the management of suspected HIT, based on 4Ts (thrombocytopenia, timing of platelet count drop, thrombosis or other sequelae, and other causes of thrombocytopenia) scores. Three patients were excluded because they had received dabigatran with a creatinine clearance <15 mL/min. Patients' records were analyzed longitudinally, with 12 months follow-up from the time of initiation of dabigatran, for occurrence of thrombosis, dabigatran-related complications, and outcome. Patients with chronic kidney disease, hepatic impairment, mechanical heart valves, active bleeding, and extremes of weights (<50 and >120 kg) were excluded from the study. Arterial thrombosis was not observed in any of our patients. The platelet counts normalized in all patients except for 2, which was attributed to the underlying comorbidities. We did not observe any hemorrhagic events or significant thrombosis during the follow-up period. Eight patients died from nonthrombotic causes, which were unrelated to adverse effects of dabigatran. Based on our findings, dabigatran could be considered a safe and effective agent in the management of HIT, particularly in the developing countries, where there could be issues with the cost and availability of other agents recommended for this condition. Further studies are needed to validate our findings. PMID- 30285277 TI - Predicting the time needed for environmental systematic reviews and systematic maps. AB - Systematic reviews (SRs) and systematic mapping aim to maximize transparency and comprehensiveness while minimizing subjectivity and bias. These are time consuming and complex tasks, so SRs are considered resource intensive, but published estimates of systematic-review resource requirements are largely anecdotal. We analyzed all Collaboration for Environmental Evidence (CEE) SRs (n = 66) and maps (n = 20) published from 2012 to 2017 to estimate the average number of articles retained at each review stage. We also surveyed 33 experienced systematic reviewers to collate information on the rate at which those stages could be completed. In combination, these data showed that the average CEE SR takes an estimated 164 d (full-time equivalent) (SD 23), and the average CEE systematic map (SM) (excluding critical appraisal) takes 211 d (SD 53). While screening titles and abstracts is widely considered time-consuming, metadata extraction and critical appraisal took as long or longer to complete, especially for SMs. Given information about the planned methods and evidence base, we created a software tool that predicts time requirements of a SR or map with evidence-based defaults as a starting point. Our results shed light on the most time-consuming stages of the SR and mapping processes, will inform review planning, and can direct innovation to streamline processes. Future predictions of effort required to complete SRs and maps could be improved if authors provide more details on methods and results. PMID- 30285278 TI - Leptin acts in the carotid bodies to increase minute ventilation during wakefulness and sleep and augment the hypoxic ventilatory response. AB - KEY POINTS: Leptin is a potent respiratory stimulant. A long functional isoform of leptin receptor, LepRb , was detected in the carotid body (CB), a key peripheral hypoxia sensor. However, the effect of leptin on minute ventilation (VE ) and the hypoxic ventilatory response (HVR) has not been sufficiently studied. We report that LepRb is present in approximately 74% of the CB glomus cells. Leptin increased carotid sinus nerve activity at baseline and in response to hypoxia in vivo. Subcutaneous infusion of leptin increased VE and HVR in C57BL/6J mice and this effect was abolished by CB denervation. Expression of LepRb in the carotid bodies of LepRb deficient obese db/db mice increased VE during wakefulness and sleep and augmented the HVR. We conclude that leptin acts on LepRb in the CBs to stimulate breathing and HVR, which may protect against sleep disordered breathing in obesity. ABSTRACT: Leptin is a potent respiratory stimulant. The carotid bodies (CB) express the long functional isoform of leptin receptor, LepRb , but the role of leptin in CB has not been fully elucidated. The objectives of the current study were (1) to examine the effect of subcutaneous leptin infusion on minute ventilation (VE ) and the hypoxic ventilatory response to 10% O2 (HVR) in C57BL/6J mice before and after CB denervation; (2) to express LepRb in CB of LepRb -deficient obese db/db mice and examine its effects on breathing during sleep and wakefulness and on HVR. We found that leptin enhanced carotid sinus nerve activity at baseline and in response to 10% O2 in vivo. In C57BL/6J mice, leptin increased VE from 1.1 to 1.5 mL/min/g during normoxia (P < 0.01) and from 3.6 to 4.7 mL/min/g during hypoxia (P < 0.001), augmenting HVR from 0.23 to 0.31 mL/min/g/Delta PMID- 30285279 TI - DNA prime-protein boost vaccine encoding HLA-A2, HLA-A24 and HLA-DR1 restricted epitopes of CaNA2 against visceral leishmaniasis. AB - Visceral leishmaniasis is a tropical and neglected disease with an estimated 200 000-400 000 cases and 60 000 deaths worldwide each year. Currently, no clinically valid vaccine is available for this disease. In this study, we formulated DNA and protein vaccines encoding HLA-A2, HLA-A24 and HLA-DR1 restricted epitopes of CaNA2 against visceral leishmaniasis. We predicted the secondary and tertiary structures, surface properties, subcellular localization, potential binding sites and HLA-A2, HLA-A24 and HLA-DR1 restricted epitopes of CaNA2. The best candidate CpG ODN (2395, M362, D-SL03 or 685) was screened out as a DNA vaccine adjuvant. We also prepared Kmp-11 and Kmp-11/CaNA2 DNA and protein vaccines, respectively, for comparison. BALB/c mice were immunized with a DNA prime-protein boost immunization strategy and challenged with a newly isolated Leishmania strain from an individual with visceral leishmaniasis. The IgG antibody titers showed that our vaccine had strong immunogenicity with a long duration, especially cellular immunity. The spleen parasite burden of each group demonstrated that the CaNA2 vaccine had a certain immune protective effect on visceral leishmaniasis in BALB/c mice, and the amastigote reduction rate reached 76%. Preliminary safety tests confirmed the safety of the vaccine. Our work demonstrates that the HLA-A2, HLA-A24 and HLA-DR1 restricted epitope CaNA2 DNA prime-protein boost vaccine may be a safe and effective epitope vaccine candidate against visceral leishmaniasis.

AB - Heterointerface engineering can be used to develop excellent catalysts through electronic coupling effects between different components or phases. As one kind of promising Pt-free electrocatalysts for hydrogen evolution reaction (HER), pure phased metal phosphide exhibits the unfavorable factor of strong or weak H* adsorption performance. Here, 6 nm wall-thick Ni2 P-NiP2 hollow nanoparticle polymorphs combining metallic Ni2 P and metalloid NiP2 with observable heterointerfaces are synthesized. It shows excellent catalytic performance toward the HER, requiring an overpotential of 59.7 mV to achieve 10 mA cm-2 with a Tafel slope of 58.8 mV dec-1 . Density functional theory calculations verify electrons' transfer from P to Ni at the heterointerfaces, which decreases the absolute value of H* adsorption energy and simultaneously enhance electronic conductivity. That is, the heterojunctions balance the metallic Ni2 P and the metalloid NiP2 to form an optimized phosphide polymorph catalyst for the HER. Furthermore, this polymorph combination is used with NiFe-LDH nanosheets to form an alkaline electrolyzer. It shows highly desirable electrochemical properties, which can reach 10 mA cm-2 in 1 m KOH at 1.48 V and be driven by an AAA battery with a nominal voltage of 1.5 V. The work about interfacial charge transfer might provide an insight into designing excellent polymorph catalysts. PMID- 30285281 TI - Cancer Statistics for Hispanics/Latinos, 2018. AB - Cancer is the leading cause of death among Hispanics/Latinos, who represent the largest racial/ethnic minority group in the United States, accounting for 17.8% (57.5 million) of the total population in the continental United States and Hawaii in 2016. In addition, more than 3 million Hispanic Americans live in the US territory of Puerto Rico. Every 3 years, the American Cancer Society reports on cancer occurrence, risk factors, and screening for Hispanics in the United States based on data from the National Cancer Institute, the North American Association of Central Cancer Registries, and the Centers for Disease Control and Prevention. For the first time, contemporary incidence and mortality rates for Puerto Rico, which has a 99% Hispanic population, are also presented. An estimated 149,100 new cancer cases and 42,700 cancer deaths will occur among Hispanics in the continental United States and Hawaii in 2018. For all cancers combined, Hispanics have 25% lower incidence and 30% lower mortality compared with non-Hispanic whites, although rates of infection-related cancers, such as liver, are up to twice as high in Hispanics. However, these aggregated data mask substantial heterogeneity within the Hispanic population because of variable cancer risk, as exemplified by the substantial differences in the cancer burden between island Puerto Ricans and other US Hispanics. For example, during 2011 to 2015, prostate cancer incidence rates in Puerto Rico (146.6 per 100,000) were 60% higher than those in other US Hispanics combined (91.6 per 100,000) and 44% higher than those in non-Hispanic whites (101.7 per 100,000). Prostate cancer is also the leading cause of cancer death among men in Puerto Rico, accounting for nearly 1 in 6 cancer deaths during 2011-2015, whereas lung cancer is the leading cause of cancer death among other US Hispanic men combined. Variations in cancer risk are driven by differences in exposure to cancer-causing infectious agents and behavioral risk factors as well as the prevalence of screening. Strategies for reducing cancer risk in Hispanic populations include targeted, culturally appropriate interventions for increasing the uptake of preventive services and reducing cancer risk factor prevalence, as well as additional funding for Puerto Rico-specific and subgroup-specific cancer research and surveillance. PMID- 30285282 TI - Inducible nitric oxide synthase: An asset to neutrophils. AB - Neutrophils play a key role in innate immune responses against foreign intrusion and influence the subsequent instigation of adaptive immune response. Nitric oxide (NO) synthesized by neutrophil nitric oxide synthase (NOS) profoundly modulates their diverse physiological responsibilities furthermore encompassing pathological implications. Neutrophils are the active participants in diverse inflammatory and cardiovascular disorders but neutrophil nitric oxide synthase (NOS) remains enigmatic on various aspects. This review focuses on inducible NOS (iNOS) and makes an attempt to address its potential impact in neutrophil pathophysiology, their differentiation, functionality, and survival. We described the scenario from its expressional modulation, by pro- and anti-inflammatory cytokines governing the extent and duration of neutrophil immune response, to iNOS catalysis, the intracellular compartmentalization, and protein-protein interactions determining its microenvironment, activity and its contribution as a potential signaling protein apart from its role as signal transducer. Further, the relevance of investigating the unexplored facets of iNOS biology in neutrophils and possible prototypes of iNOS regulation is also exemplified in related cellular systems. PMID- 30285283 TI - Remaking the world in our own image: vulnerability, resilience and adaptation as historical discourses. AB - A warming climate and less predictable weather patterns, as well as an expanding urban infrastructure susceptible to geophysical hazards, make the world an increasingly dangerous place, even for those living in high-income countries. It is an opportune moment, therefore, from the vantage point of the second decade of the twenty-first century, to review the terms and concepts that have been employed regularly over the past 50 years to assess risk and to measure people's exposure to such events in the light of the wider geopolitical context. In particular, it is useful to examine 'vulnerability', 'resilience', and 'adaptation', the principal theoretical concepts that, from an historical perspective, have dominated disaster studies since the end of the Second World War. In addition, it is valuable to enquire as to the extent to which such discourses were ideological products of their time, which sought to explain societies and their environments from the stance of competing conceptual frameworks. PMID- 30285284 TI - Single-Source Bismuth (Transition Metal) Polyoxovanadate Precursors for the Scalable Synthesis of Doped BiVO4 Photoanodes. AB - Single-source precursors are used to produce nanostructured BiVO4 photoanodes for water oxidation in a straightforward and scalable drop-casting synthetic process. Polyoxometallate precursors, which contain both Bi and V, are produced in a one step reaction from commercially available starting materials. Simple annealing of the molecular precursor produces nanocrystalline BiVO4 films. The precursor can be designed to incorporate a third metal (Co, Ni, Cu, or Zn), enabling the direct formation of doped BiVO4 films. In particular, the Co- and Zn-doped photoanodes show promise for photoelectrochemical water oxidation, with photocurrent densities >1 mA cm-2 at 1.23 V vs reversible hydrogen electrode (RHE). Using this simple synthetic process, a 300 cm2 Co-BiVO4 photoanode is produced, which generates a photocurrent of up to 67 mA at 1.23 V vs RHE and demonstrates the scalability of this approach. PMID- 30285285 TI - Putting Complex Older Persons First: How the Centers for Medicare and Medicaid Services 2019 Payment Proposal Fails Older Americans. AB - In July 2018, the Centers for Medicare and Medicaid Services (CMS) released its proposed Medicare Physician Fee Schedule rule for calendar year 2019 (MPFS2019). The proposal sets forth CMS-recommended updates to Medicare payment policies, payment rates, and quality provisions for services provided in the next calendar year. From year to year, the rule also can serve as a vehicle for soliciting input on new payment proposals and changes to existing policies. Among the payment and quality proposals in the MPFS2019 proposal, CMS proposed extensive changes to Current Procedural Terminology codes that are the framework for documentation and payment for office-based evaluation and management (E/M) services. The American Geriatrics Society (AGS) believes the proposed payment methodology changes for E/M services would have had a significant negative impact on care for older Americans. On September 10, 2018, the AGS submitted its comments on this proposal and other aspects of the rule, and the AGS also submitted a comment letter signed by 41 organizations from an AGS-led multispecialty coalition. The coalition also worked collaboratively on outreach to Congress, which included visits to Capitol Hill and a coalition letter stressing our collective support for reducing the burden of documentation for clinicians and our opposition to the proposed changes in payment methodology. In all letters, we noted that the AGS and members of our coalition hoped to work collaboratively with CMS and other stakeholders to develop a refined approach that would achieve the best possible outcomes for patients, particularly frail older Americans with multiple chronic conditions. In releasing their final MPFS2019, CMS postponed the E/M coding collapse for at least two years, a decision that speaks to the hard work of the AGS, its members, and the multi specialty coalition, and which opens the door for further discussions about the future of payment for E/M services so critical to older people. PMID- 30285286 TI - A Programmed Anti-Inflammatory Nanoscaffold (PAIN) as a 3D Tool to Understand the Brain Injury Response. AB - Immunology is the next frontier of nano/biomaterial science research, with the immune system determining the degree of tissue repair. However, the complexity of the inflammatory response represents a significant challenge that is essential to understand for the development of future therapies. Cell-instructive 3D culture environments are critical to improve our understanding of the link between the behavior and morphology of inflammatory cells and to remodel their response to injury. This study has taken two recent high-profile innovations-functional peptide-based hydrogels, and the inclusion of anti-inflammatory agents via coassembly-to make a programmed anti-inflammatory nanoscaffold (PAIN) with unusual and valuable properties that allows tissue-independent switching of the inflammatory cascade. Here, extraordinary durability of the anti-inflammatory agent allows, for the first time, the development of a 3D culture system that maintains the growth and cytoskeletal reorganization of brain tissue, while also facilitating the trophic behavior of brain cells for 22 d in vitro. Notably, this behavior was confirmed within an active scar site due to the unprecedented resilience to the presence of inflammatory cells and enzymes in the brain. Efficacy of the culture system is demonstrated via novel insights about inflammatory cell behavior, which would be impossible to obtain via in vivo experimentation. PMID- 30285287 TI - Impressum.

PMID- 30285289 TI - Pretreated Macrophage-Membrane-Coated Gold Nanocages for Precise Drug Delivery for Treatment of Bacterial Infections. AB - Pathogenic bacterial infections and drug resistance make it urgent to develop new antibacterial agents with targeted delivery. Here, a new targeting delivery nanosystem is designed based on the potential interaction between bacterial recognizing receptors on macrophage membranes and distinct pathogen-associated molecular patterns in bacteria. Interestingly, the expression of recognizing receptors on macrophage membranes increases significantly when cultured with specific bacteria. Therefore, by coating pretreated macrophage membrane onto the surface of a gold-silver nanocage (GSNC), the nanosystem targets bacteria more efficiently. Previously, it has been shown that GSNC alone can serve as an effective antibacterial agent owing to its photothermal effect under near infrared (NIR) laser irradiation. Furthermore, the nanocage can be utilized as a delivery vehicle for antibacterial drugs since the gold-silver nanocage presents a hollow interior and porous wall structure. With significantly improved bacterial adherence, the Sa-M-GSNC nanosystem, developed within this study, is effectively delivered and retained at the infection site both via local or systemic injections; the system also shows greatly prolonged blood circulation time and excellent biocompatibility. The present work described here is the first to utilize bacterial pretreated macrophage membrane receptors in a nanosystem to achieve specific bacterial-targeted delivery, and provides inspiration for future therapy based on this concept. PMID- 30285290 TI - Mesoporous Organosilica Hollow Nanoparticles: Synthesis and Applications. AB - Hollow periodic mesoporous organosilicas (PMOs) with molecularly homogeneous organic functional groups in the inorganic pore walls are attracting more and more attention due to the high surface areas, tunable pore sizes, low densities, large cavities in the center, permeable thin shells, and versatile organic inorganic hybrid frameworks, which make them promising in a variety of applications including adsorption, catalysis, drug delivery, and nanotheranostics. Herein, recent advances in the synthesis of hollow PMO nanoparticles with various organic moieties are summarized, and the mechanism and new insights of synthesis approaches, including hard-core templating methods, liquid-interface assembly methods, and the interfacial reassembly and transformation strategy are discussed in-depth. Meanwhile, the design principles, properties, and synthetic strategies for some smart hollow architectures such as multishelled hollow PMOs, yolk-shell structured PMOs, and nonspherical hollow PMOs are discussed. Moreover, the typical applications of hollow PMO nanomaterials as nanoreactors for chemical transformations and nanoplatforms for biomedicine are summarized. Finally, the challenges and prospects for the future development of hollow PMOs are described. PMID- 30285291 TI - Impact of eosinophil-peroxidase (EPX) deficiency on eosinophil structure and function in mouse airways. AB - Eosinophil peroxidase (EPX) is a major constituent of the large cytoplasmic granules of both human and mouse eosinophilic leukocytes. Human EPX deficiency is a rare, autosomal-recessive disorder limited to the eosinophil lineage. Our intent was to explore the impact of EPX gene deletion on eosinophil content, structure, and function. In response to repetitive intranasal challenge with a filtrate of the allergen, Alternaria alternata, we found significantly fewer eosinophils peripherally and in the respiratory tracts of EPX-/- mice compared to wild-type controls; furthermore, both the major population (Gr1-/lo ) and the smaller population of Gr1hi eosinophils from EPX-/- mice displayed lower median fluorescence intensities (MFIs) for Siglec F. Quantitative evaluation of transmission electron micrographs of lung eosinophils confirmed the relative reduction in granule outer matrix volume in cells from the EPX-/- mice, a finding analogous to that observed in human EPX deficiency. Despite the reduced size of the granule matrix, the cytokine content of eosinophils isolated from allergen challenged EPX-/ - and wild-type mice were largely comparable to one another, although the EPX-/- eosinophils contained reduced concentrations of IL-3. Other distinguishing features of lung eosinophils from allergen-challenged EPX-/- mice included a reduced fraction of surface TLR4+ cells and reduced MFI for NOD1. Interestingly, the EPX gene deletion had no impact on eosinophil-mediated clearance of gram-negative Haemophilus influenzae from the airways. As such, although no clinical findings have been associated with human EPX deficiency, our findings suggest that further evaluation for alterations in eosinophil structure and function may be warranted. PMID- 30285292 TI - Risk communication and risk perception: lessons from the 2011 floods in Brisbane, Australia. AB - Risk communication and risk perception are critical factors in disaster management. Governments at all levels play a part in communicating risk, whereas the perception of risk entails active roles by community participants, including potential and actual victims of disasters. This paper discusses these matters in relation to the floods in Brisbane, Australia, in 2011. The findings are based on interviews with representatives of households whose dwellings or business premises were fully or partially inundated by the waters. The research shows how important it is to recognise the problems of institutional fragmentation in terms of communication and the active engagement of recipients in understanding and interpreting flood risk information (especially for slow-onset riverine flooding, such as that suffered by Brisbane). Locally targeted information on risk is of vital importance in avoiding the misinterpretation of warning information in relation to environmental cues and in promoting adequate responses. The paper concludes with some recommendations. PMID- 30285293 TI - Presynaptic loss of dynamin-related protein 1 impairs synaptic vesicle release and recycling at the mouse calyx of Held. AB - KEY POINTS: This study characterizes the mechanisms underlying defects in synaptic transmission when dynamin-related protein 1 (DRP1) is genetically eliminated. Viral-mediated knockout of DRP1 from the presynaptic terminal at the mouse calyx of Held increased initial release probability, reduced the size of the synaptic vesicle recycling pool and impaired synaptic vesicle recycling. Transmission defects could be partially restored by increasing the intracellular calcium buffering capacity with EGTA-AM, implying close coupling of Ca2+ channels to synaptic vesicles was compromised. Acute restoration of ATP to physiological levels in the presynaptic terminal did not reverse the synaptic defects. Loss of DRP1 impairs mitochondrial morphology in the presynaptic terminal, which in turn seems to arrest synaptic maturation. ABSTRACT: Impaired mitochondrial biogenesis and function is implicated in many neurodegenerative diseases, and likely affects synaptic neurotransmission prior to cellular loss. Dynamin-related protein 1 (DRP1) is essential for mitochondrial fission and is disrupted in neurodegenerative disease. In this study, we used the mouse calyx of Held synapse as a model to investigate the impact of presynaptic DRP1 loss on synaptic vesicle (SV) recycling and sustained neurotransmission. In vivo viral expression of Cre recombinase in ventral cochlear neurons of floxed-DRP1 mice generated a presynaptic-specific DRP1 knockout (DRP1-preKO), where the innervated postsynaptic cell was unperturbed. Confocal reconstruction of the calyx terminal suggested SV clusters and mitochondrial content were disrupted, and presynaptic terminal volume was decreased. Using postsynaptic voltage-clamp recordings, we found that DRP1-preKO synapses had larger evoked responses at low frequency stimulation. DRP1-preKO synapses also had profoundly altered short-term plasticity, due to defects in SV recycling. Readily releasable pool size, estimated with high-frequency trains, was dramatically reduced in DRP1-preKO synapses, suggesting an important role for DRP1 in maintenance of release competent SVs at the presynaptic terminal. Presynaptic Ca2+ accumulation in the terminal was also enhanced in DRP1-preKO synapses. Synaptic transmission defects could be partially rescued with EGTA-AM, indicating close coupling of Ca2+ channels to SV distance normally found in mature terminals may be compromised by DRP1-preKO. Using paired recordings of the presynaptic and postsynaptic compartments, recycling defects could not be reversed by acute dialysis of ATP into the calyx terminals. Taken together, our results implicate a requirement for mitochondrial fission to coordinate postnatal synapse maturation. PMID- 30285295 TI - 5,12-Diaminotetracenes: The Impact of Orbital Interactions between the Acene pi System and Amino Groups on Their Electronic States. AB - 5,12-Diamino-substituted tetracenes with various N-substituents have been prepared, and their molecular structural changes upon oxidation have been evaluated in association with their electronic structures. The N-substituents influence both the electronic and molecular structures of the oxidized species of 5,12-diaminotetracenes. The tetracene moiety of 5,12-bis(N,N dianisylamino)tetracene retained its planarity during the course of two successive one-electron oxidations, whereas 5,12-bis(N,N-dimethylamino)tetracene and 5,12-bis(N-anisyl-N-methylamino)tetracene underwent substantial structural changes into butterfly like structures through a simultaneous two-electron oxidation process. The molecular structures in the oxidized states were closely related to the nature of the highest occupied orbitals, which were characterized by the extent of mixing between the fragment orbitals for the teracene moiety and the substituted amino groups in 5,12-diaminotetracenes. As a consequence, the present work revealed that the extent of folding deformation of the acene moiety in the oxidized diaminoacenes could be fine-tuned by varying the N-substituents. PMID- 30285294 TI - Spore Carbon from Aspergillus Oryzae for Advanced Electrochemical Energy Storage. AB - Development of novel advanced carbon materials is playing a critical role in the innovation of electrochemical energy storage technology. Hierarchical porous spore carbon produced by Aspergillus oryzae is reported, which acts as a biofactory. Interestingly, the spore carbon not only shows a porous maze structure consisting of crosslinked nanofolds, but also is intrinsically N and P dual doped. Impressively, the spore carbon can be further embedded with Ni2 P nanoparticles, which serve as porogen to form a highly porous spore carbon/Ni2 P composite with increased surface area and enhanced electrical conductivity. To explore the potential application in lithium-sulfur batteries (LSBs), the spore carbon/Ni2 P composite is combined with sulfur, forming a composite cathode, which exhibits a high initial capacity of 1347.5 mAh g-1 at 0.1 C, enhanced cycling stability (73.5% after 500 cycles), and better rate performance than the spore carbon/S and artificial hollow carbon sphere/S counterparts. The synergistic effect on suppressing the shuttle effect of intermediate polysulfides is responsible for the excellent LSBs performance with the aid of a physical blocking effect arising from the electrical maze porous structure and the chemical adsorption effect originating from N, P dual doping and polarized compound Ni2 P. PMID- 30285297 TI - Cryptic protein interactions regulate DNA replication initiation. AB - DNA replication is a fundamental biological process that is tightly regulated in all cells. In bacteria, DnaA controls when and where replication begins by building a step-wise complex that loads the replicative helicase onto chromosomal DNA. In many low-GC Gram-positive species, DnaA recruits the DnaD and DnaB proteins to function as adaptors to assist in helicase loading. How DnaA, its adaptors and the helicase form a complex at the origin is unclear. We addressed this question using the bacterial two-hybrid assay to determine how the initiation proteins from Bacillus subtilis interact with each other. We show that cryptic interaction sites play a key role in this process and we map these regions for the entire pathway. In addition, we found that the SirA regulator that blocks initiation in sporulating cells binds to a surface on DnaA that overlaps with DnaD. The interaction between DnaA and DnaD was also mapped to the same DnaA surface in the human pathogen Staphylococcus aureus, demonstrating the broad conservation of this surface. Therefore, our study has unveiled key protein interactions essential for initiation and our approach is widely applicable for mapping interactions in other signaling pathways that are governed by cryptic binding surfaces. PMID- 30285296 TI - Rationally Designed DNA-Origami Nanomaterials for Drug Delivery In Vivo. AB - The recent decades have seen a surge of new nanomaterials designed for efficient drug delivery. DNA nanotechnology has been developed to construct sophisticated 3D nanostructures and artificial molecular devices that can be operated at the nanoscale, giving rise to a variety of programmable functions and fascinating applications. In particular, DNA-origami nanostructures feature rationally designed geometries and precise spatial addressability, as well as marked biocompatibility, thus providing a promising candidate for drug delivery. Here, the recent successful efforts to employ self-assembled DNA-origami nanostructures as drug-delivery vehicles are summarized. The remaining challenges and open opportunities are also discussed. PMID- 30285298 TI - A gene-stacking approach to overcome the trade-off between drought stress tolerance and growth in Arabidopsis. AB - The molecular breeding of drought stress-tolerant crops is imperative for stable food and biomass production. However, a trade-off exists between plant growth and drought stress tolerance. Many drought stress-tolerant plants overexpressing stress-inducible genes, such as DEHYDRATION-RESPONSIVE ELEMENT-BINDING PROTEIN 1A (DREB1A), show severe growth retardation. Here, we demonstrate that the growth of DREB1A-overexpressing Arabidopsis plants could be improved by co-expressing growth-enhancing genes whose expression is repressed under drought stress conditions. We used Arabidopsis GA REQUIRING 5 (GA5), which encodes a rate limiting gibberellin biosynthetic enzyme, and PHYTOCHROME-INTERACTING FACTOR 4 (PIF4), which encodes a transcription factor regulating cell growth in response to light and temperature, for growth improvement. We observed an enhanced biomass and floral induction in the GA5 DREB1A and PIF4 DREB1A double overexpressors compared with those in the DREB1A overexpressors. Although the GA5 DREB1A double overexpressors continued to show high levels of drought stress tolerance, the PIF4 DREB1A double overexpressors showed lower levels of stress tolerance than the DREB1A overexpressors due to repressed expression of DREB1A. A multiomics analysis of the GA5 DREB1A double overexpressors showed that the co-expression of GA5 and DREB1A additively affected primary metabolism, gene expression and plant hormone profiles in the plants. These multidirectional analyses indicate that the inherent trade-off between growth and drought stress tolerance in plants can be overcome by appropriate gene-stacking approaches. Our study provides a basis for using genetic modification to improve the growth of drought stress-tolerant plants for the stable production of food and biomass.

PMID- 30285300 TI - Brief Computer-Based Information Processing Measures are Linked to White Matter Integrity in Pediatric-Onset Multiple Sclerosis. AB - BACKGROUND AND PURPOSE: Pediatric-onset multiple sclerosis (POMS) is a demyelinating disorder with unique clinical challenges. A brief computer administered cognitive screening battery measuring processing speed (Cogstate) and the Brief International Cognitive Assessment in MS (BICAMS) detect cognitive impairment in POMS. The neuroanatomic correlates of these deficits are incompletely understood. The purpose of this study is to define the neuroanatomic underpinnings of deficits identified with cognitive screening batteries in POMS. METHODS: Participants with POMS and age-matched healthy controls (HCs) were screened with Cogstate and BICAMS. Diffusion tensor imaging assessed region-wise and tractography-based fractional anisotropy (FA). RESULTS: The POMS (n = 15) and HC (n = 21) groups were matched on age (mean ages 17.9 +/- 3.2 vs. 17.8 +/- 3.3 years, respectively) and on an estimate of general intellectual functioning. The Cogstate composite revealed significant slowing in POMS relative to HCs (P = .004), but the BICAMS composite did not significantly distinguish the groups (P = .10). The Cogstate composite showed moderate-to-strong correlations with regional FA (r = -.67 to -.82) and significantly associated with uncinate fasciculus FA following multiple comparisons correction (P = .002) in POMS. However, the BICAMS composite measure showed only weak-to-moderate correlations with FA in POMS (r = .19 to -.57), with none surviving multiple comparisons correction. CONCLUSIONS: Computer-administered measures of cognitive processing are particularly sensitive in POMS and are closely linked to white matter FA. PMID- 30285301 TI - Adjusting Aggregation Modes, Photophysical and Photovoltaic Properties of Diketopyrrolopyrrole-Based Small Molecules by Introducing B<-N Bonds. AB - The packing mode of small molecular semiconductors in thin films is an important factor that controls the performance of their optoelectronic devices. Designing and changing the packing mode via molecular engineering is challenging. Three structurally-related diketopyrrolopyrrole (DPP) based molecules are synthesized to study the effect of replacing C-C bonds by isoelectronic dipolar B<-N bonds. By replacing one of the bridging C-C bonds on the peripheral fluorene units of the DPP molecules by a coordinative B<-N bond and changing the B<-N bond orientation, the optical absorption, fluorescence, and excited state lifetime of the molecules can be tuned. The substitution alters the preferential aggregation of the molecules in solid state from H-type (for C-C) to J-type (for B<-N). Introducing B<-N bonds therefore provides a subtle way of controlling the packing mode. The photovoltaic properties of the DPP molecules are evaluated in bulk heterojunctions with a fullerene acceptor and reveal moderate performance as a consequence of suboptimal morphologies, bimolecular recombination, and triplet state formation. PMID- 30285302 TI - Catalyst-Free Oxytrifluoromethylation of Alkenes through Paired Electrolysis in Organic-Aqueous Media. AB - A mild, catalyst-free electrochemical oxytrifluoromethylation of alkenes has been developed. The procedure is based on the paired electrolysis of sodium triflinate and water in an undivided cell. Anodic oxidation of the triflinate anion generates trifluoromethyl radicals that react with the alkene. Water plays a dual role as oxidant for the cathode and nucleophile. The method has been utilized to prepare a diverse set of 1-hydroxy-2-trifluoromethyl compounds in moderate to excellent yields (27-94 %). Alcohols have also been tested as nucleophiles for this versatile method with moderate yields. Facile recycling of the electrolyte has been demonstrated, and application of electricity avoids the use of stoichiometric amounts of oxidizers in a safe and environmentally benign reaction. PMID- 30285303 TI - Ecological change alters the evolutionary response to harvest in a freshwater fish. AB - Harvesting can induce rapid evolution in animal populations, yet the role of ecological change in buffering or enhancing that response is poorly understood. Here, we developed an eco-genetic model to examine how ecological changes brought about by two notorious invasive species, zebra and quagga mussels, influence harvest-induced evolution and resilience in a freshwater fish. Our study focused on lake whitefish (Coregonus clupeaformis) in the Laurentian Great Lakes, where the species supports valuable commercial and subsistence fisheries, and where the invasion of dreissenid (zebra and quagga) mussels caused drastic shifts in ecosystem productivity. Using our model system, we predicted faster rates of evolution of maturation reaction norms in lake whitefish under pre-invasion ecosystem conditions when growth and recruitment of young to the population were high. Slower growth rates that occurred under post-invasion conditions delayed when fish became vulnerable to the fishery, thus decreasing selection pressure and lessening the evolutionary response to harvest. Fishing with gill nets and traps nets generally selected for early maturation at small sizes, except when fishing at low levels with small mesh gill nets under pre-invasion conditions; in this latter case, evolution of delayed maturation was predicted. Overall, the invasion of dreissenid mussels lessened the evolutionary response to harvest, while also reducing the productivity and commercial yield potential of the stock. These results demonstrate how ecological conditions shape evolutionary outcomes and how invasive species can have a direct effect on evolutionary responses to harvest and sustainability.

AB - OBJECTIVE: Although accumulating evidence indicates that macrophages are central players in the destructive and reparative phases of periodontal disease, their polarization states at different stages of periodontal inflammation remain unclear. METHODS: We collected gingival biopsies from patients with chronic periodontitis (P group), gingivitis (G group), or periodontally healthy individuals (H group). Polarized macrophages were identified through immunofluorescence. M1- and M2-related cytokines were detected by immunohistochemistry. RESULTS: Compared with the H group, the P group had more M1 cells (higher M1/M2 ratio) and significantly higher TNF-alpha, IFN-gamma, IL-6, and IL-12 levels. Although the G group also exhibited higher TNF-alpha and IL-12 levels than the H group, they had similar M1/M2 ratios. The M1/M2 ratio and IFN gamma and IL-6 levels were significantly higher in the P than the G group. Among M2-related cytokines, IL-4 levels were significantly higher in the G than the H group. The M1/M2 ratio was positively correlated with clinical probing depth (PD), and both were positively correlated with IFN-gamma and IL-6. PD was negatively correlated with IL-4. CONCLUSION: Macrophage polarization in gingival tissue may be responsible for the development and progression of inflammation induced tissue destruction, and modulating macrophage function may be a potential strategy for periodontal disease management. PMID- 30285306 TI - Critical Role for Saccharomyces cerevisiae Asc1p in Translational Initiation at Elevated Temperatures. AB - The eukaryotic ribosomal protein RACK1/Asc1p is localized to the mRNA exit channel of the 40S subunit but lacks a defined role in mRNA translation. Saccharomyces cerevisiae deficient in ASC1 exhibit temperature-sensitive growth. Using this null mutant, potential roles for Asc1p in translation and ribosome biogenesis are evaluated. At the restrictive temperature the asc1Delta null mutant has reduced polyribosomes. To test the role of Asc1p in ribosome stability, cryo-EM is used to examine the structure of 80S ribosomes in an asc1Delta yeast deletion mutant at both the permissive and nonpermissive temperatures. CryoEM indicates that loss of Asc1p does not severely disrupt formation of this complex structure. No defect is found in rRNA processing in the asc1Delta null mutant. A proteomic approach is applied to survey the effect of Asc1p loss on the global translation of yeast proteins. At the nonpermissive temperature, the asc1Delta mutant has reduced levels of ribosomal proteins and other factors critical for translation. Collectively, these results are consistent with recent observations suggesting that Asc1p is important for ribosome occupancy of short mRNAs. The results show the Asc1 ribosomal protein is critical in translation during heat stress.

This transformation was achieved by regioselective C-C bond cleavage of a sterically more hindered biphenylene site by using alkene as both a directing group and a reaction moiety. Furthermore, we measured and analyzed the photophysical properties of the new multicyclic fused compounds.

AB - Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but life threatening cutaneous reactions that are most commonly caused by exposure to medications. This review assesses the efficacy and safety of cyclosporine therapy for SJS, TEN, and SJS/TEN overlap. A literature review was conducted in PubMed using the MeSH terms TEN, SJS, and cyclosporine. Five case series and one meta analysis were analyzed. From review of the existing literature, cyclosporine appears to not only have a mortality benefit in the treatment of SJS/TEN, but also a relatively safe side effect profile.

While of uncertain etiology, 95% male predominance and familial occurrence suggest a genetic basis. As copy number variations (CNVs) can cause unexplained genetic disorders, we tested for novel CNVs in a large PBS population. We genotyped 21 unrelated PBS patients by high-resolution array comparative genomic hybridization (aCGH) and phenotyped using a novel PBS severity scoring system. Available parents were screened for detected CNV via quantitative PCR (qPCR). We additionally screened for recurrence of identified novel candidate CNVs on 106 PBS probands by qPCR. We identified 10 CNVs in 8 of 21 PBS patients tested (38%). Testing confirmed inheritance from an unaffected biological parent in six patients; parental samples were unavailable in two probands. One candidate CNV includes duplication of the X-chromosome AGTR2 gene, known to function in urinary tract development. Subsequent screening of the larger PBS cohort did not identify any recurrent CNVs. Presence of CNV did not correlate with PBS severity scoring. CNVs were uncommon in this large PBS population, but analysis of identified variants may inform disease pathogenesis and reveal targets for therapeutic intervention for this rare, severe disorder. PMID- 30285311 TI - Construction of integrated microRNA and mRNA immune cell signatures to predict survival of patients with breast and ovarian cancer. AB - In the tumor microenvironment, immune cells have emerged as key regulators of cancer progression. While much work has focused on characterizing tumor-related immune cells through gene expression profiling, microRNAs (miRNAs) have also been reported to regulate immune cells in the tumor microenvironment. Using regression based computational methods, we have constructed for the first time, immune cell signatures based on miRNA expression from The Cancer Genome Atlas breast and ovarian cancer datasets. Combined with existing mRNA immune cell signatures, the integrated mRNA-miRNA leukocyte signatures are better able to delineate prognostic immune cell subsets within both cancers compared to the mRNA or miRNA signatures alone. Moreover, using the miRNA signatures, the anti-inflammatory M2 macrophages emerged as the most significantly prognostic cell type in the breast cancer data (HR [hazard ratio]: 12.9; CI [confidence interval]: 3.09-52.9; P = 4.22E-4), whereas the pro-inflammatory M1 macrophages emerged as the most prognostic immune cell type in the ovarian cancer data (HR: 0.2; CI: 0.04-0.56, P = 5.02E-3). These results suggest that our integrated miRNA and mRNA leukocyte signatures could be used to better delineate prognostic leukocyte subsets within cancers, whereas continued investigation may further support the regulatory relationships predicted between the miRNAs and immune cells found within our signature matrices.

AB - Four stable boron dipyrromethene (BODIPY)- and porphyrin-based bis-arylamine diradical dications were synthesized by two-electron oxidation of their neutral molecules. The two BODIPY-based dications have open-shell singlet ground states. UV/Vis absorption spectra of all four dications showed large redshifts in the NIR region compared to their neutral precursors with absorption maxima at 1274 and 1068 nm for the two BODIPY-based dications and 1746 and 2037 nm for the two porphyrin-based dications. Thus, two new types of NIR dyes with longer wavelengths are provided by the diradical-dication strategy, which can be applied for the generation of other NIR dyes with a range of different chromophores and auxochromes. PMID- 30285313 TI - Clinical presentation at initiation of maintenance dialysis and subsequent survival: A retrospective cohort study. AB - INTRODUCTION: Clinical practice guidelines increasingly favor a more symptom driven approach to maintenance dialysis initiation. But, little is known about the clinical presentation at dialysis initiation, such as the different kinds of signs and symptoms present at dialysis initiation, illness acuity at dialysis initiation, and how these aspects of the clinical presentation relate to subsequent survival. METHODS: This is a retrospective cohort study of a random sample of veterans who initiated dialysis between 2000 and 2009 at Veterans Affairs (VA) medical centers across the country (N = 1,691). We looked at associations between the clinical presentation (types of signs and/or symptoms and illness acuity) at the time of dialysis initiation and 1-year mortality. FINDINGS: The most common types of signs and/or symptoms at initiation were gastrointestinal (50.9%) and cardiopulmonary (48.7%). The crude mortality rate was 174.2 deaths per 1000 patients per year (95% CI 154.7, 196.1). Among different categories of signs and/or symptoms, only cardiopulmonary signs and/or symptoms were associated with a higher 1-year risk of mortality after initiation (risk ratio (RR) 1.32, 95% CI 1.05, 1.69) in adjusted analyses. Patients who were acutely ill at initiation were more likely to die during the following year as compared with those who initiated dialysis in the outpatient setting (RR 1.57, 95% CI 1.15, 2.21). DISCUSSION: With the exception of cardiopulmonary signs and/or symptoms, most signs and/or symptoms documented around the time of dialysis initiation were not associated with an increased risk of death during the year after initiation. In contrast, whether patients were acutely ill at the time of initiation was strongly associated with an increased risk of death after initiation regardless of the specific signs and/or symptoms present. Limitations of this study include retrospective study design, residual confounding, and lack of generalizability to non-VA settings. PMID- 30285314 TI - Laser Irradiation of Gd-Si and Gd-Si-Ge Colloid Mixtures for the Fabrication of Compound Nanoparticles. AB - Binary (Gd5 Si4 , GdSi) and ternary (Gd5 Si2 Ge2 ) compound nanoparticles (NPs) were prepared by laser irradiation of a mixture of colloidal solutions containing NPs of the relevant elements. It is assumed that the compound NPs are formed by heating, co-melting, and chemical interactions in the alloyed droplets. The blackbody-like radiation of the heated NPs was used for temperature control of the NP-preparation process. The obtained results demonstrate that laser irradiation of colloidal NPs provides unique possibilities not only for the synthesis of compound NPs but also for control of their phase composition and size. The synthesized Gd-based compound NPs exhibited magnetic transition at an ordering temperature, TC , in the range of 310-320 K. Thus, the magnetic properties of the synthesized particles confirm their potential for biomedical applications, in particular, for magnetic hyperthermia treatment.

PMID- 30285316 TI - Endotoxin-Free Preparation of Graphene Oxide and Graphene-Based Materials for Biological Applications. AB - Due to their two-dimensional structure and unique properties, graphene and its derivatives have been extensively studied for their potential applications in various fields ranging from electronics to composites. Particularly, their high surface area, electrical conductivity, mechanical strength, dispersability in aqueous phase, and possibility of surface modification make them promising candidates for biomedical applications including biosensing, drug delivery, tissue engineering, cell imaging, and therapeutics. The functioning of graphene nanosheets in these applications is dependent on their structure and properties, which are mainly determined by their preparation and processing methods. Exfoliation techniques are the most common methods for preparation of graphene nanosheets for biomedical applications due to their high yield and scalability. Further modification of these methods is necessary to produce biocompatible and toxin-free graphene that can be safely incorporated into biological media. Here, we describe protocols for chemical and mechanical exfoliation of graphite to produce endotoxin-free and highly stable graphene oxide and graphene dispersions. Additional protocols are provided for proper pre- and post-processing of nanosheets and endotoxin measurement techniques. (c) 2018 by John Wiley & Sons, Inc.

AB - Therapeutic proteins are a continuously growing class of pharmaceuticals and comprise several drug candidates with potential performance-enhancing properties. In particular, activin receptor competitors, such as the ActRII-Fc fusion proteins Sotatercept (ActRIIA-Fc) and Luspatercept (modified ActRIIB-Fc), have the potential for being misused as doping agents in sports as they were found to inhibit negative regulators of late-stage erythropoiesis. Within this study, ammonium sulfate precipitation, immunoaffinity purification, tryptic digestion, and liquid chromatography-tandem mass spectrometry (LC-MS/MS) were employed to develop an assay for the combined detection of Sotatercept and Luspatercept in doping control serum samples. The assay was optimized, comprehensively characterized, and found to be fit-for-purpose for application to sports drug testing. It complements existing tests for ActRII-Fc fusion proteins and expands the range of available detection methods for novel protein therapeutics. PMID- 30285319 TI - Dinuclear Lanthanide Complexes Based on a Schiff-base Ligand: Free Lattice Solvent Inducing the Single Molecule Magnet Behavior of Dy2 Compound. AB - Syntheses, crystal structures and magnetic properties are described for a series of seven-coordinate dinuclear lanthanide complexes of compositions Dy2 L2 (1) (H3 L=2-{[bis(2-hydroxy-3-ethoxybenzyl)(aminoethyl)amino]methyl}phenol) and Ln2 L2 ?MeCN (Ln=Dy (2), Sm (3), Eu (4), Gd (5), Tb (6), Ho (7)). The reaction of Dy(NO3 )3 ?6 H2 O with one equivalent of H3 L at 70 degrees C in DMF/EtOH under autogenous pressure gave compound 1. Complexes 2-7 were prepared by means of the same method as that used for 1, except DMF was replaced by MeCN as the reaction solvent and Dy(NO3 )3 ?6 H2 O was changed to the corresponding lanthanide salts. Complexes 1-7 possess the similar Ln2 cores bridged by MU2 -phenoxyl oxygen atoms. The slight difference between 1 and 2-7 arises from the existence of free MeCN molecule in 2-7. The purposeful introduction of solvent MeCN molecule changes the crystal system from triclinic for 1 to monoclinic for 2 and alters the Dy-O-Dy angles and Dy???Dy distances, consequentially resulting into dramatic influences on the magnetic properties of 1 and 2. Complex 1 shows no SMM character, while compound 2 with free MeCN molecule exhibits a field-induced slow magnetization relaxation behavior. Complete active space self-consistent field (CASSCF) calculations were performed on two Dy2 compounds to rationalize the observed difference in the magnetic behavior. Theoretical calculations reveal that the energy gap between the lowest two Kramers doublets of individual DyIII fragment for 2 is higher than those of 1 (1_a and 1_b). This conlusion is consistant with the experimental result that complex 2 exhibits better magnetic properties. This work proposes an ingenious strategy for inducing the SMM behavior in the Dy2 compounds.

PMID- 30285321 TI - Outcomes of 219 chronic myeloid leukaemia patients with additional chromosomal abnormalities and/or tyrosine kinase domain mutations. AB - INTRODUCTION: To confirm the role of additional chromosomal abnormalities (ACAs) and kinase domain (KD) mutations in the progression and outcomes of Chronic myeloid leukaemia (CML) patients and the connection between them, we analysed the ACAs and KD mutations of 219 CML patients admitted to our hospital. METHODS: Cytogenetic analysis of metaphases was performed to detect ACAs, and the BCR-ABL1 KD was sequenced to detect KD mutations. RESULTS: Twenty-four patients (11.0%) had ACAs in addition to the BCR-ABL1 or t(9;22)(q34;q11) translocation. The most common abnormality was trisomy 8. Twelve different KD mutations were observed in 13 out of 53 imatinib-resistant patients (24.5%). p.(Y235H) (n = 3; 23.07%), p.(F359V) and p.(T315I) (n = 2; 15.38%) presented most frequently. KD mutations subtypes (p.(E255K), p.(T315I), p.(F359V), p.(M244V) and p.(L298V)) coexisted with ACAs. The incidence of CML progression was 12/22 (54.5%) in the group of patients with ACAs and/or KD mutations and 2/143 (1.4%) in the group of patients without ACAs or KD mutations (CI 95%, P < 0.001) and was higher in the KD mutations group than in the ACAs group (P = 0.046). The group of patients with ACAs and/or KD mutations had more men than the group of patients without ACAs or KD mutations (P = 0.013). CONCLUSION: We conclude that ACAs and/or KD mutations are related to CML progression and are adverse outcome factors. Their presence exhibits gender differences and is more common in males. p.(E255K), p.(T315I), p.(F359V), p.(M244V) and p.(L298V) emerge more frequently when ACAs and KD mutations coexist. PMID- 30285322 TI - Neocortical Microdissection at Columnar and Laminar Resolution for Molecular Interrogation. AB - The heterogeneous organization of the mammalian neocortex poses a challenge for elucidating the molecular mechanisms underlying its physiological processes. Although high-throughput molecular methods are increasingly deployed in neuroscience, their anatomical specificity is often lacking. In this unit, we introduce a targeted microdissection technique that enables extraction of high quality RNA and proteins at high anatomical resolution from acutely prepared brain slices. We exemplify its utility by isolating single cortical columns and laminae from the mouse primary somatosensory (barrel) cortex. Tissues can be isolated from living slices in minutes, and the extracted RNA and protein are of sufficient quantity and quality to be used for RNA sequencing and mass spectrometry. This technique will help to increase the anatomical specificity of molecular studies of the neocortex, and the brain in general, as it is applicable to any brain structure that can be identified using optical landmarks in living slices.

AB - BACKGROUND: Childhood obesity has a worldwide association with serious health problems and complications that increase the risk of illness and death. AIM: To identify and assess the factors contributing to overweight and obesity among school students in north Jordan. METHOD: A descriptive cross-sectional study involving 1,554 students was conducted between October 2014 and February 2015. RESULTS: More than two thirds (70%) of participants were normal weight (5th percentile-<85th percentile), while 12% were overweight and 13% were obese. The prevalence of obesity was high (20%) among those eating snacks three times per day. The prevalence of overweight was high (12%) among those who followed no regular physical activity programme. CONCLUSION: Collaboration is required between policymakers, healthcare professionals, business and community leaders, schools and local organisations to create suitable environments that support healthy lifestyles for children and young people.

PMID- 30285407 TI - Construction of Stimuli-Responsive Functional Materials via Hierarchical Self Assembly Involving Coordination Interactions. AB - Supramolecular self-assembly, which creates the ordered structures as a result of spontaneous organization of building blocks driven by noncovalent interactions (NCIs), is ubiquitous in nature. Recently, it has become increasingly clear that nature often builds up complex structures by employing a hierarchical self assembly (HSA) strategy, in which the components are brought together in a stepwise process via multiple NCIs. Inspired by the dedicated biological structures in nature, HSA has been widely explored to construct well-defined assemblies with increasing complexity. The employment of direct metal-ligand bonds to drive the formation of discrete metallosupramolecular architectures has proven to be a highly efficient strategy to prepare structurally diverse architectures like two-dimensional (2-D) polygons and three-dimensional (3-D) polyhedra with well-defined shapes, sizes, and geometries. Such well-defined organometallic assemblies provide an ideal platform for designing novel artificial supramolecular systems with the increasing complexity though HSA. The presence of a well-defined organometallic scaffold brings an additional dimension to the final nanoscale structures. Moreover, the multilevel dynamic nature of hierarchical self-assemblies brings more structural and functional possibilities of resultant supramolecular systems. This Account will focus on our recent advance on construction of stimuli-responsive functional materials through HSA involving coordination interactions. In our study, a series of functionalized metallacycles were first constructed through coordination-driven self-assembly (CDSA). Then, the secondary noncovalent interaction sites were integrated within the functionalized metallacycle system via either preassembly or postassembly approach. Different segments, such as alkyl chains, dendrimers, cholesteryl moiety, covalent macrocycles, and even polymeric fragments, which could provide hydrophobic and hydrophilic interactions, van der Waals forces, hydrogen bonding, CH-pi and pi-pi interactions, and host-guest interactions, have been utilized to provide the secondary NCIs. Further self-assembly of functionalized metallacycles gives rise to the formation of complex higher-order structures driven by other NCIs by taking advantages of orthogonal property of coordination bonds with other NCIs. By changing the type of additional NCIs embodied in building blocks, different supramolecular architectures, such as the ordered nanostructures, supramolecular polymers and gels, fluorescent materials and sensors, have been successfully prepared with the tailored chemical and physical properties. In particular, the dynamic nature of coordination bonds as well as other NCIs endows final assemblies with stimuli-responsive functions. Collectively, our studies suggest that combining coordination and other NCIs in a well-defined and precise manner is a highly efficient strategy to achieve the complex architectures and functional materials. Therefore, it is very promising to develop the desired functional materials with high precision and fidelity by employing HSA involving coordination interactions. PMID- 30285408 TI - Amphiphile-Induced Phase Transition of Liquid Crystals at Aqueous Interfaces. AB - Monolayer assemblies of amphiphiles at planar interfaces between thermotropic liquid crystals (LCs) and an aqueous phase can give rise to configurational transitions of the underlying LCs. A common assumption has been that a reconfiguration of the LC phase is caused by an interdigitation of the hydrophobic tails of amphiphiles with the molecules of the LC at the interface. A different mechanism is discovered here, whereby reorientation of the LC systems is shown to occur through lowering of the orientation-dependent surface energy of the LC due to formation of a thin isotropic layer at the aqueous interface. Using a combination of atomistic molecular dynamics simulations and experiments, we demonstrate that a monolayer of specific amphiphiles at an aqueous interface can cause a local nematic-to-isotropic phase transition of the LC by disturbing the antiparallel configuration of the LC molecules. These results provide new insights into the interfacial, molecular-level organization of LCs that can be exploited for rational design of biological sensors and responsive systems. PMID- 30285409 TI - Template-Free Synthesis of Two-Dimensional Fe/N Codoped Carbon Networks as Efficient Oxygen Reduction Reaction Electrocatalysts. AB - A direct pyrolysis and template-free synthesis strategy is demonstrated to synthesize the two-dimensional (2-D) Fe/N codoped carbon networks by virtue of 2 D graphitic-carbon nitride (g-C3N4) intermediates derived from melamine. Because of the stabilization and steric hindrance of additional N ligands with bisnitrogen-containing groups (phenanthroline, phthalonitrile, and phenylenediamine), the thin graphitic-layered Fe/N codoped carbon materials have successfully inherited the 2-D morphology from the g-C3N4 intermediate after direct carbonization treatment. After the easy removal of inactive Fe particles, the resultant sample exhibits numerous well-dispersed Fe atoms embedded in the carbon layers with a hierarchical (meso- and micro-) porous structure. Owing to the high active site density and open porous structure, the thin graphitic layered Fe/N codoped carbon electrocatalysts exhibit superior oxygen reduction reaction performance (a half-wave potential of 0.88 V and a kinetics current density of 3.8 mA cm-2), even better than the commercial Pt/C catalysts (0.85 V and 1.6 mA cm-2, respectively). The facile and effective synthesis strategy without template to build the graphene-like nanoarchitectures inherited from the 2-D intermediates will lead to a great development of 2-D carbon materials in various electrochemical applications. PMID- 30285410 TI - Doping beta-CoMoO4 Nanoplates with Phosphorus for Efficient Hydrogen Evolution Reaction in Alkaline Media. AB - Mass production of hydrogen by electrolysis of water largely hinges on the development of highly efficient and economical electrocatalysts for hydrogen evolution reaction (HER). Though having the merits of high earth abundance, easy availability, and tunable composition, transition-metal oxides are usually deemed as poor electrocatalysts for HER. Herein, we demonstrate that doping beta-CoMoO4 nanoplates with phosphorus can turn them into active electrocatalysts for HER. Theoretical calculation and experimental studies unravel that enhanced electrical conductivity and optimized hydrogen adsorption free energy are major causes for the improvement of intrinsic activity. As a result, only an overpotential of 138 mV is required to drive hydrogen evolving at a current density of 10 mA cm-2 in 1 M KOH for P-doped beta-CoMoO4, which outstrips many recently reported transition metal oxides and is just slightly inferior to commercial Pt/C. This work opens a new route to tune the HER performance of transition-metal oxides. PMID- 30285411 TI - Soft Conducting Polymer Hydrogels Cross-Linked and Doped by Tannic Acid for Spinal Cord Injury Repair. AB - Mimicking soft tissue mechanical properties and the high conductivity required for electrical transmission in the native spinal cord is critical in nerve tissue regeneration scaffold designs. However, fabricating scaffolds of high conductivity, tissue-like mechanical properties, and excellent biocompatibility simultaneously remains a great challenge. Here, a soft, highly conductive, biocompatible conducting polymer hydrogel (CPH) based on a plant-derived polyphenol, tannic acid (TA), cross-linking and doping conducting polypyrrole (PPy) chains is developed to explore its therapeutic efficacy after a spinal cord injury (SCI). The developed hydrogels exhibit an excellent electronic conductivity (0.05-0.18 S/cm) and appropriate mechanical properties (0.3-2.2 kPa), which can be achieved by controlling TA concentration. In vitro, a CPH with a higher conductivity accelerated the differentiation of neural stem cells (NSCs) into neurons while suppressing the development of astrocytes. In vivo, with relatively high conductivity, the CPH can activate endogenous NSC neurogenesis in the lesion area, resulting in significant recovery of locomotor function. Overall, our findings evidence that the CPHs without being combined with any other therapeutic agents have stimulated tissue repair following an SCI and thus have important implications for future biomaterial designs for SCI therapy. PMID- 30285413 TI - Fabrication of Supramolecular Bioactive Surfaces via beta-Cyclodextrin-Based Host Guest Interactions. AB - Supramolecular host-guest interactions provide a facile and versatile basis for the construction of sophisticated structures and functional assemblies through specific molecular recognition of host and guest molecules to form inclusion complexes. In recent years, these interactions have been exploited as a means of attaching bioactive molecules and polymers to solid substrates for the fabrication of bioactive surfaces. Using a common host molecule, beta cyclodextrin (beta-CD), and various guest molecules as molecular building blocks, we fabricated several types of bioactive surfaces with multifunctionality and/or function switchability via host-guest interactions. Other groups have also taken this approach, and several intelligent designs have been developed. The results of these investigations indicate that, compared to the more common covalent bonding-based methods for attachment of bioactive ligands, host-guest based methods are simple, more broadly ("universally") applicable, and allow convenient renewal of bioactivity. In this Spotlight on Applications, we review and summarize recent developments in the fabrication of supramolecular bioactive surfaces via beta-CD-based host-guest interactions. The main focus is on the work from our laboratory, but highlights on work from other groups are included. Applications of the materials are also emphasized. These surfaces can be categorized into three types based on: (i) self-assembled monolayers, (ii) polymer brushes, and (iii) multilayered films. The host-guest strategy can be extended from material surfaces to living cell surfaces, and work along these lines is also reviewed. Finally, a brief perspective on the developments of supramolecular bioactive surfaces in the future is presented.

AB - Self-adjusting omniphilic nanocarriers (OPNs) with a multisolvent aptitude were prepared via a Schiff base reaction between chitosan, a natural polysaccharide, and bioactive aldehydes. Experimental studies supported by atomistic molecular dynamics simulations revealed these OPNs can encapsulate insoluble molecular cargo, transport them in aqueous or lipid environments, and deliver them through cross-phase barriers. N-imine dynamic covalent bonds have been incorporated to endow the OPNs with pH responsiveness, also allowing the amplification of their bioactivity, as demonstrated in vitro with the ability to delay fungal proliferation in wheat grains. The reported OPNs hold remarkable potential as biocompatible nanocarriers for the effective delivery of active agents in agriculture, medicine, and cosmetics. PMID- 30285414 TI - Tandem Enzymatic Self-Assembly and Slow Release of Dexamethasone Enhances Its Antihepatic Fibrosis Effect. AB - Many chronic liver diseases will advance to hepatic fibrosis and, if without timely intervention, liver cirrhosis or even hepatocellular carcinoma. Anti inflammation could be a standard therapeutic strategy for hepatic fibrosis treatment, but a "smart" strategy of hepatic fibrosis-targeted, either self assembly or slow release of an anti-inflammation drug ( e.g., dexamethasone, Dex), has not been reported. Herein, we rationally designed a hydrogelator precursor Nap-Phe-Phe-Lys(Dex)-Tyr(H2PO3)-OH (1-Dex-P) and proposed a tandem enzymatic strategy of self-assembly and slow release of Dex, with which the precursor exhibited much stronger antihepatic fibrosis effect than Dex both in vitro and in vivo. Enzymatic and cell experiments validated that 1-Dex-P was first dephosphorylated by alkaline phosphatase to yield Nap-Phe-Phe-Lys(Dex)-Tyr OH (1-Dex), which self-assembled into nanofiber 1-Dex. The nanofiber was then hydrolyzed by esterase to transform into nanofiber 1, accompanied by slow release of Dex. We anticipate that our "smart" tandem enzymatic strategy could be widely employed to design more sophisticated drug delivery systems to achieve enhanced therapeutic efficacy than free drugs in the future.

AB - Although digital systems fabricated from carbon-nanotube-based field-effect transistors (CNFETs) promise significant energy efficiency benefits, realizing these benefits requires a complementary CNFET technology, i.e., CNFET CMOS, comprising both PMOS and NMOS CNFETs. Furthermore, this CNFET CMOS process must be robust ( e.g., air-stable), tunable ( e.g., ability to control CNFET threshold voltages), and silicon CMOS compatible (to integrate within existing manufacturing facilities and process flows). Despite many efforts, such a silicon CMOS compatible CNT doping strategy for forming NMOS CNFETs does not exist. Techniques today are either not air-stable (using reactive low work function metals), not solid-state or silicon CMOS compatible (employing soluble molecular dopants in ionic solutions), or have not demonstrated precise control over the amount of doping (for setting threshold voltage, VT). Here, we demonstrate an electrostatic doping technique that meets all of these requirements. The key to our technique is leveraging atomic layer deposition (ALD) to encapsulate CNTs with nonstoichiometric oxides. We show that ALD allows for precise control of oxide stoichiometry, which translates to direct control of the amount of CNT doping. We experimentally demonstrate the ability to modulate the strength of the p-type conduction branch by >2500* (measured as the change in current at fixed bias), realize NMOS CNFETs with n-type conduction ~500* stronger than p-type conduction (also measured by the relative current at fixed biases), and tune VT over a ~1.5 V range. Moreover, our technique is compatible with other doping schemes; as an illustration, we combine electrostatic doping and low work function contact engineering to achieve CNFET CMOS with symmetric NMOS and PMOS ( i.e., CNFET ON-current for NMOS and PMOS is within 6% of each other). Thus, this work realizes a solid-state, air-table, very large scale integration and silicon CMOS compatible doping strategy, enabling integration of CNFET CMOS within standard fabrication processes today.

AB - Light olefins such as ethylene and propylene form the foundation of the modern chemical industry, with yearly production volumes well into the hundreds of millions of metric tons. Currently, these light olefins are mainly produced via energy-intensive steam cracking. Alternatively, oxidative dehydrogenation (ODH) of light alkanes to produce olefins allows for lower operation temperatures and extended catalyst lifetimes, potentially leading to valuable process efficiencies. The potential benefits of this route have led to significant research interest due to the wide availability of natural gas from shale deposits. Advances in this area have still not yielded catalysts that are sufficiently selective to olefins for industrial implementation, and ODH still remains a holy grail of selective alkane oxidation research. The main challenge in selective oxidation lies in preventing the overoxidation of the desired product, such as propylene during propane oxidation, to CO and CO2. Research into selective heterogeneous catalysts for the oxidative dehydrogenation of propane has led to the extensive use of vanadium oxide-based catalysts, and studies on the surface mechanism involved have been used to improve the catalytic activity of the material. Despite decades of research, however, selectivity toward propylene has not proven satisfactory at industrially relevant conversions. It is imperative for new catalytic systems that minimize product overoxidation to be developed for future applications of oxidative dehydrogenation processes. While rational catalyst design has been successful in developing homogeneous catalyst systems, its practical use in heterogeneous catalyst development remains modest. The complexity of surfaces with a variety of terminations and bulk structures, let alone their modification by the chemical potential of a reaction mixture, makes heterogeneous catalyst discovery serendipitous in many cases. The catalyst family presented in this Account is no exception. The importance of catalysis research lies in exploring the science behind serendipity. In this Account, we will first present our initial discovery of boron nitride (BN) as an unexpected catalyst for the oxidative dehydrogenation of light alkanes. Beyond its surprising activity, BN also drew interest due to its low selectivity to carbon oxides. This observation made BN distinct from previously studied metal oxide catalysts for selective alkane oxidation. We narrowed down its unique reactivity to the oxygen functionalization of the catalyst surface, particularly the formation of B-O species as probed by various spectroscopic techniques. In investigating the critical role of each of the structural elements during ODH, we discovered that not only BN but an entire class of boron-containing compounds are active and selective for the formation of propylene from propane. All these materials form a complex oxidized surface with a distribution of BO x surface sites. This discovery opens the doors to a new field of boron-based oxidation chemistry that currently has more questions than answers. We aim to make this Account a starting point for the research community to explore these new materials to understand their surface mechanisms and the surface species that offer a unique selectivity toward olefinic products. Effective use of these materials may lead to novel processes for efficient use of abundant light alkane resources by oxidation chemistry.

AB - As an important semiconductor nanomaterial, InP nanowires (NWs) grown with a typical vapor-liquid-solid mechanism are still restricted from their low electron mobility for practical applications. Here, nonpolar-oriented defect-free wurtzite InP NWs with electron mobility of as high as 2000 cm2 V-1 s-1 can be successfully synthesized via Pd-catalyzed vapor-solid-solid growth. Specifically, PdIn catalyst particles are involved and found to expose their PdIn{210} planes at the InP nucleation frontier due to their minimal lattice mismatch with nonpolar InP{2110} and {1100} planes. This appropriate lattice registration would then minimize the overall free energy and enable the highly crystalline InP NW growth epitaxially along the nonpolar directions. Because of the minimized crystal defects, the record-high electron mobility of InP NWs ( i.e., 2000 cm2 V-1 s-1 at an electron concentration of 1017 cm-3) results, being close to the theoretical limit of their bulk counterparts. Furthermore, once the top-gated device geometry is employed, the device subthreshold slopes can be impressively reduced down to 91 mV dec-1 at room temperature. In addition, these NWs exhibit a high photoresponsivity of 104 A W-1 with fast rise and decay times of 0.89 and 0.82 s, respectively, in photodetection. All these results evidently demonstrate the promise of nonpolar-oriented InP NWs for next-generation electronics and optoelectronics. PMID- 30285418 TI - Surface Fouling of Ultrananocrystalline Diamond Microelectrodes during Dopamine Detection: Improving Lifetime via Electrochemical Cycling. AB - In this work, we report the electrochemical response of a boron-doped ultrananocrystalline diamond (BDUNCD) microelectrode during long-term dopamine (DA) detection. Specifically, changes to its electrochemical activity and electroactive area due to DA byproducts and surface oxidation are studied via scanning electron microscopy, energy dispersive spectroscopy, electrochemical impedance spectroscopy, and silver deposition imaging (SDI). The fouling studies with amperometry (AM) and fast scan cyclic voltammetry (FSCV) methods suggest that the microelectrodes are heavily fouled due to poor DA-dopamine- o-quinone cyclization rates followed by a combination of polymer formation and major changes in their surface chemistry. SDI data confirms the presence of the insulating polymer with sparsely distributed tiny electroactive regions. This resulted in severely distorted DA signals and a 90% loss in signal starting as early as 3 h for AM and a 56% loss at 6.5 h for FSCV. This underscores the need for cleaning of the fouled microelectrodes if they have to be used long-term. Out of the three in vivo suitable electrochemical cycling cleaning waveforms investigated, the standard waveform (-0.4 V to +1.0 V) provides the best cleaned surface with a fully retained voltammogram shape, no hysteresis, no DA signal loss (a 90 +/- 0.72 nA increase), and the smallest charge transfer resistance value of 0.4 +/- 0.02 MOmega even after 6.5 h of monitoring. Most importantly, this is the same waveform that is widely used for in vivo detection with carbon fiber microelectrodes. Future work to test these microelectrodes for more than 24 h of DA detection is anticipated. PMID- 30285419 TI - Manipulation of Glutathione-Mediated Degradation of Thiol-Maleimide Conjugates. AB - The retro Michael-type addition and thiol exchange of thioether succinimide click linkages in response to thiol-containing environments offers a novel strategy for the design of glutathione-sensitive degradable hydrogels for controlled drug delivery. Here we characterize the kinetics and extent of the retro Michael-type addition and thiol exchange with changes in both the p Ka of the thiols and the identity of N-substituents of maleimides. A series of N-substituted thioether succinimides were prepared through typical Michael-type addition. Model studies (1H NMR, HPLC) of 4-mercaptophenylacetic acid (MPA, p Ka 6.6) conjugated to N ethyl maleimide (NEM), N-phenyl maleimide (NPM), or N-aminoethyl maleimide (NAEM) and then incubated with glutathione showed half-lives of conversion from 3.1 to 18 h, with extents of conversion from approximately 12% to 90%. The variations in the rates of exchange and hydrolytic ring opening appear to be mediated by resonance effects, electron-withdrawing capacity of the N-substituted moiety, as well as the potential for intramolecular catalytic hydrogen bonding of amine substituents with water (particularly in the case of ring opening). Further model studies of 4-mercaptohydrocinnamic acid (MPP, p Ka 7.0) and N-acetyl-l-cysteine (NAC, p Ka 9.5) conjugated to selected N-substituted maleimides and then incubated with glutathione showed half-lives of conversion from 3.6 to 258 h, with extents of conversion from approximately 1% to 90%. A higher p Ka of the thiol decreased the rate of the exchange reaction and limited the impact of other electronic effects of N-substituents on the extents of conversion. Additional factors affecting the conversion kinetics were studied on NEM conjugates. The kinetics of the retro Michael-type addition and exchange reaction were not hindered by thiol traps of lower p Ka, but were retarded in conditions of lower pH. These studies shed light into details of thiol and maleimide design that could be used to tune the rates of degradation of drug and polymer conjugates for a variety of applications. PMID- 30285420 TI - Effect of the Processing Route on the Thermoelectric Performance of Nanostructured CuPb18SbTe20. AB - The quaternary AgPb18SbTe20 compound (abbreviated as LAST) is a prominent thermoelectric material with good performance. Endotaxially embedded nanoscale Ag rich precipitates contribute significantly to decreased lattice thermal conductivity (kappalatt) in LAST alloys. In this work, Ag in LAST alloys was completely replaced by the more economically available Cu. Herein, we conscientiously investigated the different routes of synthesizing CuPb18SbTe20 after vacuum-sealed-tube melt processing, including (i) slow cooling of the melt, (ii) quenching and annealing, and consolidation by (iii) spark plasma sintering (SPS) and also (iv) by the state-of-the-art flash SPS. Irrespective of the method of synthesis, the electrical (sigma) and thermal (kappatot) conductivities of the CuPb18SbTe20 samples were akin to those of LAST alloys. Both the flash-SPSed and slow-cooled CuPb18SbTe20 samples with nanoscale dislocations and Cu-rich nanoprecipitates exhibited an ultralow kappalatt ~ 0.58 W/m.K at 723 K, comparable with that of its Ag counterpart, regardless of the differences in the size of the precipitates, type of precipitate-matrix interfaces, and other nanoscopic architectures. The sample processed by flash SPS manifested higher figure of merit ( zT ~ 0.9 at 723 K) because of better optimization and a trade off between the transport properties by decreasing the carrier concentration and kappalatt without degrading the carrier mobility. In spite of their comparable sigma and kappatot, zT of the Cu samples is low compared to that of the Ag samples because of their contrasting thermopower values. First-principles calculations attribute this variation in the Seebeck coefficient to dwindling of the energy gap (from 0.1 to 0.02 eV) between the valence and conduction bands in MPb18SbTe20 (M = Cu or Ag) when Cu replaces Ag. PMID- 30285421 TI - Global Pattern of Microplastics (MPs) in Commercial Food-Grade Salts: Sea Salt as an Indicator of Seawater MP Pollution. AB - Previous studies have identified microplastics (MPs) in commercial table salts but could not exactly address the origin of the MPs because of several limitations. The present study is based on the hypothesis that commercial sea salts can act as an indicator of MP pollution in the surrounding environment unless the MPs are filtered out during the manufacturing process. A total of 39 different salt brands produced at geospatially different sites, including 28 sea salt brands from 16 countries/regions on six continents, were investigated. A wide range of MP content (in number of MPs per kg of salt; n/kg) was found: 0 1674 n/kg (excluding one outlier of 13 629 n/kg) in sea salts, 0-148 n/kg in rock salt, and 28-462 n/kg in lake salt. Relatively high MP content was identified in sea salts produced in Asian countries/regions. The abundance of MPs in unrefined sea salts ( n = 25) exhibited significant linear correlations with plastic emissions from worldwide rivers ( r2= 0.33; p = 0.003) and with the MP pollution levels in surrounding seawater ( r2= 0.46; p = 0.021) in the published literature. The results indicate that not only is Asia a hot spot of global plastic pollution, as previous studies have suggested, but also that sea salt can be a good indicator of the magnitude of MP pollution in the surrounding marine environment.

AB - We report the synthesis of a key mononuclear intermediate complex based on a quinoid ligand and its further metalation to afford the corresponding hetero bimetallic compound that revealed unique properties. An unprecedented hetero bimetallic effect in coordination chemistry could be indeed observed and exploited to prepare, through selective ligand exchange, a tetranuclear complex (Pd-Ni-Ni-Pd) absorbing light up to the far-red region. Most importantly, we describe here to the best of our knowledge the first use of bischelating ligand for ligand exchange, and this approach can be considered as a new route for incorporating planar units to access multi-heteronuclear complexes. The origin of this specific ligand exchange as well as of the nature of the electronic excited states of the relevant structures were investigated by first-principle calculations.

AB - We present a Lagrangian correction for the energy change upon releasing constraints imposed on coupled cluster amplitudes. We demonstrate that our correction (i) eliminates the systematic basis set error of the posthoc F12 treatment in orbital optimized methods and (ii) can be used to relax the F12 amplitudes and significantly reduce the sensitivity of the core-valence correlation energies to the exponent of the correlation factor, while retaining the low cost of the fixed amplitude approach. PMID- 30285424 TI - Optimal Binding of Acetylene to a Nitro-Decorated Metal-Organic Framework. AB - We report the first example of crystallographic observation of acetylene binding to -NO2 groups in a metal-organic framework (MOF). Functionalization of MFM-102 with -NO2 groups on phenyl groups leads to a 15% reduction in BET surface area in MFM-102-NO2. However, this is coupled to a 28% increase in acetylene adsorption to 192 cm3 g-1 at 298 K and 1 bar, comparable to other leading porous materials. Neutron diffraction and inelastic scattering experiments reveal the role of -NO2 groups, in cooperation with open metal sites, in the binding of acetylene in MFM 102-NO2. PMID- 30285426 TI - Machine Learning Configuration Interaction. AB - We propose the concept of machine learning configuration interaction (MLCI) whereby an artificial neural network is trained on-the-fly to predict important new configurations in an iterative selected configuration interaction procedure. We demonstrate that the neural network can discriminate between important and unimportant configurations, that it has not been trained on, much better than by chance. MLCI is then used to find compact wave functions for carbon monoxide at both stretched and equilibrium geometries. We also consider the multireference problem of the water molecule with elongated bonds. Results are contrasted with those from other ways of selecting configurations: first-order perturbation, random selection, and Monte Carlo configuration interaction. Compared with these other serial calculations, this prototype MLCI is competitive in its accuracy, converges in significantly fewer iterations than the stochastic approaches, and requires less time for the higher-accuracy computations. PMID- 30285425 TI - Endocannabinoid Virodhamine Is an Endogenous Inhibitor of Human Cardiovascular CYP2J2 Epoxygenase. AB - The human body contains endogenous cannabinoids (endocannabinoids) that elicit effects similar to those of Delta9-tetrahydrocanabinol, the principal bioactive component of cannabis. The endocannabinoid virodhamine (O-AEA) is the constitutional isomer of the well-characterized cardioprotective and anti inflammatory endocannabinoid anandamide (AEA). The chemical structures of O-AEA and AEA contain arachidonic acid (AA) and ethanolamine; however, AA in O-AEA is connected to ethanolamine via an ester linkage, whereas AA in AEA is connected through an amide linkage. O-AEA is involved in regulating blood pressure and cardiovascular function. We show that O-AEA is found at levels 9.6-fold higher than that of AEA in porcine left ventricle. On a separate note, the cytochrome P450 (CYP) epoxygenase CYP2J2 is the most abundant CYP in the heart where it catalyzes the metabolism of AA and AA-derived eCBs to bioactive epoxides that are involved in diverse cardiovascular functions. Herein, using competitive binding studies, kinetic metabolism measurements, molecular dynamics, and wound healing assays, we have shown that O-AEA is an endogenous inhibitor of CYP2J2 epoxygenase. As a result, the role of O-AEA as an endogenous eCB inhibitor of CYP2J2 may provide a new mode of regulation to control the activity of cardiovascular CYP2J2 in vivo and suggests a potential cross-talk between the cardiovascular endocannabinoids and the cytochrome P450 system.

AB - Exposure to environmental pollutants, particularly during pregnancy, can have adverse consequences on child development but little is known about the effects of pollutant mixtures on endogenous metabolism in pregnant women. We aimed to identify urinary metabolic signatures associated with low level exposure to multiple environmental pollutants in pregnant women from the INMA (INfancia y Medio Ambiente) birth cohort (Spain, N = 750). 35 chemical exposures were quantified in first trimester blood samples (organochlorine pesticides, PCBs, PFAS), in cord blood (mercury), and twice in urine at 12 and 32 weeks of pregnancy (metals, phthalates, bisphenol A). 1H nuclear magnetic resonance (NMR) metabolic profiles of urine were acquired in the same samples as pollutants. We explored associations between exposures and metabolism through an exposome metabolome wide association scan and multivariate O2PLS modeling. Novel and reproducible associations were found across two periods of pregnancy for three nonpersistent pollutants and across two subcohorts for four of the persistent pollutants. We found novel metabolic signatures associated with arsenic exposure: TMAO and dimethylamine possibly related to gut microbial methylamine metabolism and homarine related to fish intake. Tobacco smoke exposure was related to coffee metabolism and PCBs with 3-hydroxyvaleric acid, usually released under ketoacidosis. These findings will have implications for further understanding of maternal-fetal health, and health across the life-course.

AB - The reaction of [ZnGe18(Hyp)6] (Hyp = Si(SiMe3)3) with Pt(PPh3)4 gives the neutral polynuclear complex of Ge9(Hyp)3 units [HypZn-Ge9(Hyp)3-Pt-Ge9(Hyp)3 ZnHyp], 1. Within 1, the central Pt atom is bound eta3 to both Ge9(Hyp)3 units to which further ZnHyp units are bound again, symmetric eta3, to the other side of the Ge9(Hyp)3 units, leading to the longest chain compound exhibiting Ge9(Hyp)3 units that is known to date. Dissolved crystals of 1 give a violet solution, showing an absorption maximum around 543 nm. Further UV-vis investigations on different M xGe9(Hyp)3 compounds show that the absorption maximum depends on the number of transition metal atoms bound to the Ge9(Hyp)3 unit, which is supported by TD-DFT calculations.

AB - The establishment of novel design strategies to target chiral rodlike MOFs, elusively faced until now, is one of the most straightforward manners to widen the scope of MOFs. Here we describe our last advances on the application of the metalloligand design strategy toward the development of efficient routes to obtain chiral rodlike MOFs. To this end, we have used as precursor an enantiopure homochiral hexanuclear wheel (1), derived from the amino acid d-valine, which, after a supramolecular reorganization into a one-dimensional homochiral chain with the same configuration as 1-led to the formation of a homochiral rodlike MOF (2) exhibiting rare etd topology.

AB - Headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry was adopted for the simultaneous determination of seven chlorophenols (CPs) from honey and canned-yellow-peach samples. A covalent organic framework made of 1,3,5-triformylphloroglucinol (Tp) and benzidine (BD) was used as the SPME fiber coating to preconcentrate the acetylation derivatives of the CPs. The main experimental parameters including derivatization conditions, extraction temperature and time, headspace volume, salt concentration, and desorption temperature were investigated. The fiber showed a high extraction capability for the CPs. The limits of detection (LODs) for the analytes were 0.3 0.7 MUg kg-1 for honey and 0.8-1.8 MUg kg-1 for canned-yellow-peach samples, suggesting good sensitivity for the method. The response linearity was 2.4-250 MUg kg-1 for 2-CP and 3,4-CP and 1.0-150 MUg kg-1 for the other remaining analytes in the honey samples. For the canned-yellow-peach samples, the response linearity was 6.0-300 MUg kg-1 for 2-CP and 3,4-CP and 3.0-200 MUg kg-1 for the others. The correlation coefficients were higher than 0.9919. Good repeatability (RSD < 11.9%) for the method and high recoveries (70.2-113%) of the analytes were observed under the optimal conditions. The established method was satisfactorily applied for the analysis of honey and canned-yellow-peach samples. PMID- 30285432 TI - A Microbore Tubing Based Spiral for Multistep Cell Fractionation. AB - Cells were separated with the aid of a multistep spiral fractionation device, utilizing hydrodynamic forces in a spiral tubing. The spiral was fabricated using "off-the-shelf" microbore tubing, allowing for cheap and fast prototyping to achieve optimal cell separation. As a first step, a model system with 20 and 40 MUm beads was used to demonstrate the effectiveness of the multistep separation device. With an initial purity of 5%, a separation purity of 83% was achieved after a two-step separation with the addition of 0.1% polyethylene glycol (PEG) 8000. Next, doxorubicin-resistant polyploid giant breast cancer cells (MDA-MB 231) were separated from doxorubicin-sensitive monoploid small breast cancer cells in the same fashion as the beads, resulting in a purity of around 40%, while maintaining a cell viability of more than 90%. Combined with basic cell analytical methods, the hydrodynamic separation principle of the device could be envisaged to be useful for a variety of cell fractionation needs in cell biology and in clinical applications. PMID- 30285433 TI - Mitigation options of atmospheric Hg emissions in China. AB - As the Minamata Convention on Mercury comes into effect, controlling atmospheric mercury (Hg) emissions has become a compulsory goal. This study determined the mitigation options for the five Convention specified sources by considering their reduction potential of Hg emissions and the impact of future technology changes on emitted Hg forms and cross-media releases. Hg emissions will be reduced from 371 t in 2015 to 242 t in 2020 mainly by applying multipollutant control measures. Hg emissions will be reduced to 71 t in 2030 mainly with alternative measures and specific Hg removal measures (SMR). Alternative measures are effective for the studied sources except waste incineration (WI). SMR is preferentially recommended in cement clinker production (CEM) due to the benefit of sectoral emissions and local deposition. Stringent requirements of Hg emission control will promote the use of SMR in WI. In case of nonferrous metal smelting (NFMS), only 8.7 t of Hg emissions will be reduced by SMR. However, the co benefit of Hg reduction in sulfuric acid and local deposition will increase the relevance. On the contrary, applying SMR in coal-fired power plants (CFPPs) and coal-fired industrial boilers (CFIBs) requires comprehensive evaluation in terms of cost benefit and cross-media effect.

AB - Through the powerful hydrothermal method, five rare-earth (Re = Dy, Gd, Ho, Pr, and Sm) three-dimensional (3D) cluster-based metal-organic frameworks (MOFs) have been synthesized, namely, [Dy(L)(H2O)(DMF)] n (1), {[Gd(L)(H2O)(DMF)].DMF} n (2), {[Ho(L)(H2O)(DMF)].0.5DMF} n (3), {[Pr(L)(H2O)(DMF)].0.5DMF} n (4), and {[Sm(L)(H2O)1.55(DMF)0.45].DMF} n (5; H3L = terphenyl-3,4",5-tricarboxylic acid), which have been determined by single crystal X-ray analyses and PXRD characterization. Structural analyses reveal that, in 1-5, these L3- ligands are linked by five different rare-earth centers, forming the iso-structural nanoporous frameworks. PXRD patterns of bulky samples 1-5 also are consistent with theoretical PXRD patterns confirming their purity. Solid state photoluminesce of free H3L and 1-5 at room temperature also has been investigated indicating strong ligand-based emissions. Besides these, fluorescent dye Rhodamine B (RhB) can be introduced into MOF1 forming the composite material RhB@MOF1 with a high quantum yield of 35%. It is noted that, through deliberately tuning the morphologies of nanoparticle MOF1 under different ultrasonic conditions, RhB@MOF1 can be utilized as the first ratiometric fluorescent sensor to effectively discriminate l- and d-lysine from other amino acid molecules with high Ksv values and low LOD values. On the other hand, 2 was for the first time to be utilized as an excellent bifunctional MOFs-based sensing platform to detect insulin and Al3+ with a low detection limit in the human serum solution. PMID- 30285436 TI - Size Stability Study of Catalytically Active Sub-2 nm Diameter Gold Nanoparticles Synthesized with Weak Stabilizers. AB - Here we report on the very low size stability of electrocatalytically active 1.5 to 2.0 nm diameter tetrakis(hydroxymethyl)phosphonium chloride-stabilized Au nanoparticles (THPC Au2nm NPs) chemically attached to glass/indium tin oxide electrodes. The potential for oxidative dissolution of THPC Au2nm NPs in the presence of bromide is about 250 mV negative of 4 nm diameter citrate-stabilized Au NPs (Cit Au4nm NPs) and 450 mV negative of bulk Au, which provides us with an easy method to assess the size stability using anodic stripping voltammetry. The THPC Au2nm NPs show a strong CO2 reduction wave at about -0.40 V (vs RHE), which is nonexistent for the Cit Au4nm NPs or bulk Au. The THPC Au2nm NPs are also comparatively more electroactive for the hydrogen evolution reaction. In acid electrolyte, however, the potential for surface Au2O3 formation on THPC Au2nm NPs is significantly negative relative to bulk Au, and a single cycle through the surface oxide and reduction waves leads to an increase in the NP size to about 4 nm. Similarly, the THPC Au2nm NPs undergo Ostwald ripening in the presence of bromide within 5 min at potentials well before oxidation, which increases their size to 4-10 nm in diameter by 35 min. Exposure to ozone for only 1-2 min also causes the THPC Au2nm NPs to increase in size to about 4 nm. In comparison, Cit Au4nm NPs are stable under all of these conditions, requiring much longer times to change in size. These differences in reactivity and size stability are due to the different Au NP size. Sub-2 nm diameter NPs with weak stabilizers are potentially very useful for electrocatalysis, but their low oxidation potential and poor size stability are major issues of concern.

AB - Reversible glycosylation of nuclear and cytoplasmic proteins is an important regulatory mechanism across metazoans. One enzyme, O-linked N-acetylglucosamine transferase (OGT), is responsible for all nucleocytoplasmic glycosylation and there is a well-known need for potent, cell-permeable inhibitors to interrogate OGT function. Here we report the structure-based evolution of OGT inhibitors culminating in compounds with low nanomolar inhibitory potency and on-target cellular activity. In addition to disclosing useful OGT inhibitors, the structures we report provide insight into how to inhibit glycosyltransferases, a family of enzymes that has been notoriously refractory to inhibitor development.

AB - Design and development of a single atomic catalyst with high activity is desirable but proved to be very challenging in the renewable energy conversion and storage technologies. As a classic carbon material, graphene has many excellent properties and thus may be a good support to stabilize the isolated metal atoms. However, the oxygen evolution activity of a single cobalt atom supported on graphene is still very low. To improve its performance, support modification has been carried out based on a density functional theory framework for the design predication. In our theoretical study, two nitrogen formats are incorporated to the graphene substrates, including graphitic nitrogen and pyridine-like nitrogen, which are usually observed in experiment. The oxygen evolution process has been envisaged on these single cobalt atom catalysts via gas phase adsorption calculation. The electronic structure on the single Co active site can be effectively regulated by the support modification, which will contribute to its enhanced performance. Henceforth, free energy change diagrams, partial density of states, Raman spectra, and charge density difference are discussed. It is suggested that incorporating pyridine-like nitrogen on graphene is an ideal approach for the supported Co atom to achieve high OER activity, opening up new opportunity for the preparation and application of highly active and stable single atomic catalysts.

The thermodynamics of all three cleavage modes for the N H bond (i.e., proton, hydride, and hydrogen atom) were examined both experimentally and computationally. The N-H bond of 3 exhibits a p Ka of 12.1, a hydricity of Delta G degrees H- = 89 kcal/mol, and a bond dissociation free energy (BDFE) of Delta G degrees H* = 68 kcal/mol in CD3CN. Hydride transfer from 3 to the trityl cation (Delta G degrees H- = 99 kcal/mol) is exergonic but takes several hours to reach completion, indicating that 3 is a relatively poor hydride donor, both kinetically and thermodynamically. Hydrogen atom transfer from 3 to 2,6-di- tert-butyl-4-(4'-nitrophenyl)phenoxyl radical (tBu2NPArO., Delta G degrees H* = 77.8 kca/mol) occurs rapidly, illustrating the competence of 3 as a hydrogen atom donor.

AB - An aerobic photoepoxidation of alpha,beta-unsaturated ketones driven by visible light in the presence of tetramethylguanidine (3b), tetraphenylporphine (H2TPP), and molecular oxygen under mild conditions was revealed. The corresponding alpha,beta-epoxy ketones were obtained in yields of up to 94% in 96 h. The reaction time was shortened to 4.6 h by flow synthesis. The mechanism related to singlet oxygen was supported by experiments and density functional theory (DFT) calculations.

AB - It is well-known that tetrameric hemoglobin binds ligands cooperatively by undergoing a ligand-induced T -> R quaternary structure transition, a structure function relationship that has long served as a model system for understanding allostery in proteins. However, kinetic studies of the reverse, R -> T quaternary structure transition following photolysis of carbonmonoxyhemoglobin (HbCO) reveal complex behavior that may be better explained by the presence of two different R quaternary structures coexisting in thermal equilibrium. Indeed, we report here time-resolved small- and wide-angle X-ray scattering (SAXS/WAXS) patterns of HbCO following a temperature jump that not only provide unambiguous evidence for more than one R state, but also unveil the time scale for interconversion between them. Since the time scale for the photolysis-induced R -> T transition is likely different for different R-states, this structural heterogeneity must be accounted for to properly explain the kinetic heterogeneity observed in time-resolved spectroscopic studies following photolysis of HbCO.

AB - Aminoadamantane drugs are lipophilic amines that block the membrane-embedded influenza A M2 WT (wild type) ion channel protein. The comparative effects of amantadine ( Amt) and its synthetic spiro[pyrrolidine-2,2'-adamantane] (AK13) analogue in dimyristoylphosphatidylcholine (DMPC) bilayers were studied using a combination of experimental biophysical methods, differential scanning calorimetry (DSC), X-ray diffraction, solid-state NMR (ssNMR) spectroscopy, and molecular dynamics (MD) simulations. All three experimental methods pointed out that the two analogues perturbed drastically the DMPC bilayers with AK13 to be more effective at high concentrations. AK13 was tolerated in lipid bilayers at very high concentrations, while Amt was crystallized. This is an important consideration in the formulations of drugs as it designates a limitation of Amt incorporation. MD simulations verify provided details about the strong interactions of the drugs in the interface region between phosphoglycerol backbone and lipophilic segments. The two drugs form hydrogen bonding with both water and sn-2 carbonyls in their amine form or water and phosphate oxygens in their ammonium form. Such localization of the drugs explains the DMPC bilayers reorientation and their strong perturbing effect evidenced by all biophysical methodologies applied.

AB - The reaction mechanism for the synthesis of 1,3,4-oxadiazole-2(3 H)-ones from hydrazonyl chloride and CO2 in the presence of CsF/18-crown-6 and toluene, is revisited via density functional theory computations. Although this reaction was earlier classified as a 1,3-dipolar cycloaddition, we found some competing pathways involved therein. The mechanisms including the (F-CO2)- anion and the nitrile imine intermediate are some options. The dimerization of nitrile imine is another competing mechanism in this reaction. Our results show that the most favorable mechanism proceeds via a stepwise pathway without involving any nitrile imine intermediate or the (F-CO2)- anion. The F- anion, resulting from the formation of a complex between 18-crown-6 and Cs+ cation, deprotonates the nitrile imine precursor easily, which acts then as a nucleophilic anion, enhancing the reactivity of CO2 toward it. The mechanism for the reaction with COS, an isoelectronic analogue of CO2, is also explored.

AB - We combine single-molecule Forster resonance energy transfer (single-molecule FRET) experiments with extensive all-atom molecular dynamics (MD) simulations (>100 MUs) to characterize the conformational ensembles of single-stranded (ss) DNA and RNA in solution. From MD simulations with explicit dyes attached to single-stranded nucleic acids via flexible linkers, we calculate FRET efficiencies and fluorescence anisotropy decays. We find that dispersion corrected water models alleviate the problem of overly abundant interactions between fluorescent dyes and the aromatic ring systems of nucleobases. To model dye motions in a computationally efficient and conformationally exhaustive manner, we introduce a dye-conformer library, built from simulations of dinucleotides with covalently attached dye molecules. We use this library to calculate FRET efficiencies for dT19, dA19, and rA19 simulated without explicit labels over a wide range of salt concentrations. For end-labeled homopolymeric pyrimidine ssDNA, MD simulations with the parmBSC1 force field capture the overall trend in salt-dependence of single-molecule FRET based distance measurements. For homopolymeric purine ssRNA and ssDNA, the DESRES and parmBSC1 force fields, respectively, provide useful starting points, even though our comparison also identifies clear deviations from experiment. PMID- 30285444 TI - Comparison Study on the Prediction of Multiple Molecular Properties by Various Neural Networks. AB - Various neural networks, including a single layer neural network (SLNN), a deep neural network (DNN) with multilayers, and a convolution neural network (CNN) have been developed and investigated to predict multiple molecular properties simultaneously. The data set of this work contains~134 kilo molecules and their 15 properties (including rotational constant A, B, and C, dipole moment, isotropic polarizability, energy of HOMO, energy of LUMO, HOMO-LUMO gap energy, electronic spatial extent, zero point vibrational energy, internal energy at 0 K, internal energy at 298.15 K, enthalpy at 298.15 K, free energy at 298.15 K, and heat capacity at 298.15 K) at the hybrid density functional theory (DFT) level from the QM9 database. Coulomb matrix (CM) converted from the database representing every molecule uniquely and its eigenvalue are respectively used as the input of machine learning. The accuracies of predictions have been compared among SLNN, DNN and CNN by analyzing their mean absolute errors (MAEs). Using eigenvalues as input, both SLNN and DNN can give higher accuracy for the prediction of specific energy properties ( U0, U, H, and G). For the prediction of all 15 molecular properties at a time, DNN with a 3-layers network exhibits the best results using the full CM as input. The number of layers in DNN play a key role in the prediction of multiple molecular properties simultaneously. This work may provide possibility and guidance for the selection of different neural networks and input data forms for prediction and validation of multiple parameters according to different needs. PMID- 30285445 TI - How the Conformations of an Internal Junction Contribute to Fold an RNA Domain. AB - Like proteins, some RNAs fold to compact structures. We can model functional RNAs as a series of short, rigid, base-paired elements, connected by non-base-paired nucleotides that serve as junctions. These connecting regions bend and twist, facilitating the formation of tertiary contacts that stabilize compact states. Here, we explore the roles of salt and junction sequence in determining the structures of a ubiquitous connector: an asymmetric internal loop. We focus on the J5/5a junction from the widely studied P4-P6 domain of the Tetrahymena ribozyme. Following the addition of magnesium ions to fold P4-P6, this junction bends dramatically, bringing the two halves of the RNA domain together for tertiary contact engagement. Using single-molecule fluorescence resonance energy transfer (smFRET), we examine the role of sequence and salt on model RNA constructs that contain these junction regions. We explore the wild-type J5/5a junction as well as two sequence variants. These junctions display distinct, salt dependent conformations. Small-angle X-ray scattering (SAXS) measurements verify that these effects persist in the full-length P4-P6 domain. These measurements underscore the importance of junction sequence and interactions with ions in facilitating RNA folding. PMID- 30285446 TI - Diameter-Dependent Superconductivity in Individual WS2 Nanotubes. AB - Transition metal dichalcogenide nanotubes are fascinating platforms for the research of superconductivity due to their unique dimensionalities and geometries. Here we report the diameter dependence of superconductivity in individual WS2 nanotubes. The superconductivity is realized by electrochemical doping via the ionic gating technique in which the diameter of the nanotube is estimated from the periodic oscillating magnetoresistance, known as the Little Parks effect. The critical temperature of superconductivity displays an unexpected linear behavior as a function of the inverse diameter, that is, the curvature of the nanotube. The present results are an important step in understanding the microscopic mechanism of superconductivity in a nanotube, opening up a new way of superconductivity in crystalline nanostructures. PMID- 30285447 TI - WS2-Graphite Dual-Ion Batteries. AB - A novel WS2-graphite dual-ion battery (DIB) is developed by combining a conventional graphite cathode and a high-capacity few-layer WS2-flake anode. The WS2 flakes are produced by exploiting wet-jet milling (WJM) exfoliation, which allows large-scale and free-material loss production (i.e., volume up to 8 L h-1 at concentration of 10 g L-1 and exfoliation yield of 100%) of few-layer WS2 flakes in dispersion. The WS2 anodes enable DIBs, based on hexafluorophosphate (PF6-) and lithium (Li+) ions, to achieve charge-specific capacities of 457, 438, 421, 403, 295, and 169 mAh g-1 at current rates of 0.1, 0.2, 0.3, 0.4, 0.8, and 1.0 A g-1, respectively, outperforming conventional DIBs. The WS2-based DIBs operate in the 0 to 4 V cell voltage range, thus extending the operating voltage window of conventional WS2-based Li-ion batteries (LIBs). These results demonstrate a new route toward the exploitation of WS2, and possibly other transition-metal dichalcogenides, for the development of next-generation energy storage devices. PMID- 30285448 TI - Origin of Broad Emission Spectra in InP Quantum Dots: Contributions from Structural and Electronic Disorder. AB - The ensemble emission spectra of colloidal InP quantum dots are broader than achievable spectra of cadmium- and lead-based quantum dots, despite similar single-particle line widths and significant efforts invested in the improvement of synthetic protocols. We seek to explain the origin of persistently broad ensemble emission spectra of colloidal InP quantum dots by investigating the nature of the electronic states responsible for luminescence. We identify a correlation between red-shifted emission spectra and anomalous broadening of the excitation spectra of luminescent InP colloids, suggesting a trap-associated emission pathway in highly emissive core-shell quantum dots. Time-resolved pump probe experiments find that electrons are largely untrapped on photoluminescence relevant time scales pointing to emission from recombination of localized holes with free electrons. Two-dimensional electronic spectroscopy on InP quantum dots reveals multiple emissive states and increased electron-phonon coupling associated with hole localization. These localized hole states near the valence band edge are hypothesized to arise from incomplete surface passivation and structural disorder associated with lattice defects. We confirm the presence and effect of lattice disorder by X-ray absorption spectroscopy and Raman scattering measurements. Participation of localized electronic states that are associated with various classes of lattice defects gives rise to phonon-coupled defect related emission. These findings explain the origins of the persistently broad emission spectra of colloidal InP quantum dots and suggest future strategies to narrow ensemble emission lines comparable to what is observed for cadmium-based materials. PMID- 30285449 TI - Proteomic Investigation of Murine Neuronal alpha7-Nicotinic Acetylcholine Receptor Interacting Proteins. AB - The alpha7-nicotinic acetylcholine receptor (alpha7-nAChR) is a ligand-gated ion channel that is expressed widely in vertebrates and is the principal high affinity alpha-bungarotoxin (alpha-bgtx) binding protein in the mammalian CNS. alpha7-nAChRs associate with proteins that can modulate its properties. The alpha7-nAChR interactome is the summation of proteins interacting or associating with alpha7-nAChRs in a protein complex. To identify an alpha7-nAChR interactome in neural tissue, we isolated alpha-bgtx-affinity protein complexes from wild type and alpha7-nAChR knockout (alpha7 KO) mouse whole brain tissue homogenates using alpha-bgtx-affinity beads. Affinity precipitated proteins were trypsinized and analyzed with an Orbitrap Fusion mass spectrometer. Proteins isolated with the alpha7-nAChR specific ligand, alpha-bgtx, were determined to be alpha7-nAChR associated proteins. The alpha7-nAChR subunit and 120 additional proteins were identified. Additionally, 369 proteins were identified as binding to alpha-bgtx in the absence of alpha7-nAChR expression, thereby identifying nonspecific proteins for alpha7-nAChR investigations using alpha-bgtx enrichment. These results expand on our previous investigations of alpha7-nAChR interacting proteins using alpha-bgtx-affinity bead isolation by controlling for differences between alpha7-nAChR and alpha-bgtx-specific proteins, developing an improved protein isolation methodology, and incorporating the latest technology in mass spectrometry. The alpha7-nAChR interactome identified in this study includes proteins associated with the expression, localization, function, or modulation of alpha7-nAChRs, and it provides a foundation for future studies to elucidate how these interactions contribute to human disease. PMID- 30285450 TI - Skyrmions in the Moire of van der Waals 2D Magnets. AB - We explore the skyrmion formation and control possibilities in two-dimensional (2D) magnets from the ubiquitous moire pattern in vdW heterostructures. Using the example of a ferromagnetic monolayer on an antiferromagnetic substrate, we demonstrate a new origin of skyrmions in the 2D magnets from the lateral modulation of interlayer magnetic coupling by the locally different atomic registries in moire. The moire skyrmions are doubly degenerate with opposite topological charge and trapped at an ordered array of sites with the moire periodicity that can be dramatically tuned by strain and interlayer translation. At relatively strong interlayer coupling, the ground states are skyrmion lattices, where magnetic field can switch the skyrmion vorticity and location in the moire. At weak interlayer coupling limit, we find metastable skyrmion excitations on the ferromagnetic ground state that can be deterministically moved between the ordered moire trapping sites by current pulses. Our results point to potential uses of moire skyrmions both as information carriers and as drastically tunable topological background of electron transport.

PMID- 30285451 TI - Crystallization of Poly(ethylene oxide) on the Surface of Aqueous Salt Solutions Studied by Grazing Incidence Wide-Angle X-ray Scattering. AB - We report the thin layer crystallization of high-molar mass poly(ethylene oxide) (PEO) on a liquid support using a 4 M K2CO3 aqueous solution as a subphase. Because of the Hofmeister effect, PEO does not dissolve and remains at the surface during compression on a Langmuir trough. The transition from the flat pancake conformation upon compression of the spread polymer film to an entangled monolayer results in a plateau region of the Langmuir isotherm. Using grazing incidence wide-angle X-ray scattering, the final crystallization of PEO was observed, and the crystal orientation was determined. The fold surface was (209), that is, the helix axis has a tilt angle of 2.9 degrees to the normal vector of the water surface. PMID- 30285453 TI - Tunable Electron-Injection Channels of Heterostructured ZnSe@CdTe Nanocrystals for Surface-Chemistry-Involved Electrochemiluminescence. AB - Tunable charge transfer in and out of nanocrystals (NCs) is crucial to their profound light-emitting applications. Herein a convenient strategy toward tunable electron-injection channels of NCs was achieved by partially coating highly passivated CdTe NCs with unperfected ZnSe shell. Potential- and spectrum-resolved electrochemiluminescence (ECL) characterizations proved that radiative charge recombination for ECL of the heterostructured ZnSe@CdTe NCs only occurred within CdTe core, whereas configurational ions in ECL solution could electrostatically or chemically change the surface states of both the ZnSe shell and the uncoated CdTe core, resulting in tunable electron-injection channels for ECL of ZnSe@CdTe NCs. S2- anion postponed the electron-injection channel for ECL of ZnSe@CdTe NCs from -1.44 to -1.58 V, Zn2+ cation presented two electron-injection channels for ECL at -1.53 and -1.22 V, respectively, whereas Cd2+ cation enabled three electron-injection channels for ECL at -1.53, -1.18, and -0.95 V, respectively. The "valve"-like role of configurational ions on the electron-injection channels of ZnSe@CdTe NCs is promising to design novel electrochemiluminophores.

AB - Limited biocompatibility and fouling propensity can restrict real-world applications of a large variety of biosensors. Biological systems are adept at protecting and separating vital components of biological machinery with semipermeable membranes that often contain defined pores and gates to restrict transmembrane transport only to specific species.

We integrate silicon nanoribbon transistor sensors with an antifouling lipid bilayer coating that contains proton permeable carbon nanotube porin (CNTP) channels and demonstrate robust pH detection in a variety of complex biological fluids. PMID- 30285455 TI - In Vivo Laser-Mediated Retinal Ganglion Cell Optoporation Using KV1.1 Conjugated Gold Nanoparticles. AB - Vision loss caused by retinal diseases affects hundreds of millions of individuals worldwide. The retina is a delicate central nervous system tissue stratified into layers of cells with distinct roles. Currently, there is a void in treatments that selectively target diseased retinal cells, and current therapeutic paradigms present complications associated with off-target effects. Herein, as a proof of concept, we introduce an in vivo method using a femtosecond laser to locally optoporate retinal ganglion cells (RGCs) targeted with functionalized gold nanoparticles (AuNPs). We provide evidence that AuNPs functionalized with an antibody toward the cell-surface voltage-gated K+ channel subunit KV1.1 can selectively deliver fluorescently tagged siRNAs or fluorescein isothiocyanate-dextran dye into retinal cells when irradiated with an 800 nm 100 fs laser. Importantly, neither AuNP administration nor irradiation resulted in RGC death. This system provides a novel, non-viral-based approach that has the potential to selectively target retinal cells in diseased regions while sparing healthy areas and may be harnessed in future cell-specific therapies for retinal degenerative diseases. PMID- 30285456 TI - In Silico Screen and Structural Analysis Identifies Bacterial Kinase Inhibitors which Act with beta-Lactams To Inhibit Mycobacterial Growth. AB - New tools and concepts are needed to combat antimicrobial resistance. Actinomycetes and firmicutes share several eukaryotic-like Ser/Thr kinases (eSTK) that offer antibiotic development opportunities, including PknB, an essential mycobacterial eSTK. Despite successful development of potent biochemical PknB inhibitors by many groups, clinically useful microbiologic activity has been elusive. Additionally, PknB kinetics are not fully described, nor are structures with specific inhibitors available to inform inhibitor design. We used computational modeling with available structural information to identify human kinase inhibitors predicted to bind PknB, and we selected hits based on drug-like characteristics intended to increase the likelihood of cell entry. The computational model suggested a family of inhibitors, the imidazopyridine aminofurazans (IPAs), bind PknB with high affinity. We performed an in-depth characterization of PknB and found that these inhibitors biochemically inhibit PknB, with potency roughly following the predicted models. A novel X-ray structure confirmed that the inhibitors bound as predicted and made favorable protein contacts with the target. These inhibitors also have antimicrobial activity toward mycobacteria and nocardia. We demonstrated that the inhibitors are uniquely potentiated by beta-lactams but not antibiotics traditionally used to treat mycobacteria, consistent with PknB's role in sensing cell wall stress. This is the first demonstration in the phylum actinobacteria that some beta lactam antibiotics could be more effective if paired with a PknB inhibitor. Collectively, our data show that in silico modeling can be used as a tool to discover promising drug leads, and the inhibitors we discovered can act with clinically relevant antibiotics to restore their efficacy against bacteria with limited treatment options.

The key success of this unprecedented transformation of 3-aminoindazoles is the use of water as cosolvent, which could facilitate the halogen-induced ring expansion of 3-aminoindazoles under oxidative conditions. PMID- 30285458 TI - Controlling the Trajectories of Nano/Micro Particles Using Light-Actuated Marangoni Flow. AB - The ability to manipulate small objects and to produce patterns on the nano- and microscale is of great importance, both with respect to fundamentals and technological applications. The manipulation of particles with diameters of the order of 100 nm or below is a challenge because of their Brownian motion but also because of the scaling behavior of methods such as optical trapping. The unification of optical and hydrodynamic forces is a potential route toward the manipulation of tiny objects. Herein we demonstrate the trapping and manipulation of nano- and microparticles based on interfacial flows controlled by visible light, a method we denote as "Light-Actuated Marangoni Tweezer (LAMT)". We experimentally study the manipulation of particles having diameters ranging from 20 nm to 10 MUm, including quantum dots and polystyrene nano/microparticles. The particles can be manipulated by scanning a light beam along a liquid surface. In this way, we are able to define almost arbitrary particle trajectories, for example, in the form of letters. In addition, we are able to handle a number of particles in parallel by creating an optical "landscape" consisting of a multitude of laser spots. The inherent advantages of LAMTs are the linear scaling of the trapping force with the particle diameter and the fact that the force is less dependent on particle properties than in the case of conventional methods. PMID- 30285459 TI - Advantages of an Attached Semitendinosus Tendon Graft in Anterior Cruciate Ligament Reconstruction in a Rabbit Model. AB - BACKGROUND:: The semitendinosus tendon graft with an intact tibial insertion has a sustainable blood supply and might be beneficial for graft maturation after anterior cruciate ligament reconstruction (ACLR); however, its potential advantages for graft tendon-bone healing is still unclear. HYPOTHESIS:: Intact tibial insertion of the hamstring tendon can preserve enough blood supply to keep the harvested tendon alive, which can improve tendon-bone healing and the biomechanical strength of the graft. STUDY DESIGN:: Controlled laboratory study. METHODS:: Sixty-four healthy New Zealand White rabbits underwent unilateral ACLR with a semitendinosus tendon autograft after random enrollment into 2 groups (study group, n = 32 rabbits with semitendinosus tendon-preserved tibial insertions; control group, n = 32 rabbits with free semitendinosus tendons). At weeks 3, 6, 12, and 24, 8 rabbits in each group were sacrificed to evaluate tendon-bone healing by histologic staining, micro-computed tomography (micro-CT) examination, and biomechanical test. RESULTS:: The grafts in the study group maintained a similar cell count with no signs of necrosis or hypocellularity across all time points, but the grafts in the control group underwent a characteristic stage of necrosis at weeks 3 and 6. Sharpey-like fibers were observed from postoperative 3 weeks at the tendon-bone interface in the study group, and a normal insertion-like structure was formed at week 12, which became more mature at week 24. In the control group, however, Sharpey-like fibers could not be observed until week 12, and a normal transition through cartilage from bone to tendon was not observed at any time point. Histologic scores of the tendon-bone interface in the study group were significantly higher than those in the control group at week 6 ( P = .04), week 12 ( P < .001), and week 24 ( P = .04). As compared with the control group via micro-CT, the study group had a significantly smaller bone tunnel area at week 6 ( P = .01) and larger bone volume/total volume at week 3 ( P = .0026) and week 6 ( P = .01). Also, the study group had a significantly higher failure load at weeks 12 and 24 (both P = .03) and a significantly higher stiffness at week 24 ( P < .001) versus the control group. CONCLUSION:: The semitendinosus tendon graft with an intact tibial insertion in ACLR would bypass the graft avascular necrosis stage, which improves tendon-bone healing and biomechanical strength. CLINICAL RELEVANCE:: An alive graft in ACLR could improve tendon-bone healing and the biomechanical strength of the graft, which might be beneficial to early and intensive rehabilitation after ACLR. PMID- 30285460 TI - Double-Layer Rotator Cuff Repair: Anatomic Reconstruction of the Superior Capsule and Rotator Cuff Improves Biomechanical Properties in Repairs of Delaminated Rotator Cuff Tears. AB - BACKGROUND:: Delamination in rotator cuff tears has been identified as a prognostic factor for negative outcome after repair, with a reported prevalence between 38% and 88%. PURPOSE:: To compare biomechanical properties of 3 repair techniques for delaminated rotator cuff tears. STUDY DESIGN:: Controlled laboratory study. METHODS:: Eighteen fresh-frozen cadaveric shoulders were used to evaluate rotator cuff footprint reconstruction, contact area and pressure, displacement under cyclical loading, and load to failure of 3 double-row repair configurations: double-row suture repair with medial row knots (medially knotted bridge, mkB); knotless double-row repair using suture tapes (knotless bridge, klB); and knotless double-row, double-layer-specific repair (double-layer, DL). Dynamic pressure sensors were used to assess contact patterns at the footprint region in 0 degrees , 30 degrees , and 60 degrees of glenohumeral abduction and 5 rotational positions (0 degrees , 30 degrees of internal rotation, 30 degrees of external rotation, 60 degrees of internal rotation, 60 degrees of external rotation). Optical markers were used to document whole tendon and individual layer displacement after rotator cuff repair under cyclical loading for 200 cycles (10 N to 100 N at 1 Hz). Specimens were then loaded monotonically to failure at a rate of 33 mm/min. RESULTS:: Mean contact area and footprint restoration were highest in the DL group at 60 degrees of glenohumeral abduction for all rotational positions (mkB mean +/- SD, 195.4 +/- 54.3 mm2, 66.7% +/- 19.7%; klB, 250.6 +/- 34.9 mm2, 76.2% +/- 10.3%; DL, 318.4 +/- 36.6 mm2, 109.1% +/- 24.0%; P < .001). The double-layer-specific repair showed the least displacement under cyclical loading (mkB mean +/- SD, 0.53 +/- 0.18 mm; klB, 0.79 +/- 0.37 mm; DL, 0.31 +/- 0.24 mm; P = .029), most closely resembling the native tendon. Peak loads at failure were comparable between repair groups (mkB mean +/- SD, 366.92 +/- 70.59 N; klB, 280.05 +/- 77.66 N; DL, 398.35 +/- 109.04 N; P = .083). CONCLUSION:: Anatomic restoration of the superior capsular and tendon insertion in delaminated rotator cuff tears with a double-layer-specific repair configuration demonstrated superior footprint restoration with increasing abduction, while providing construct displacement comparable to the native tendon under cyclical loading. Peak load at failure was comparable between repair constructs. CLINICAL RELEVANCE:: The prevalence and clinical importance of delaminated rotator cuff tears have long been underestimated. Anatomically correct individual reconstruction of the superior capsule and rotator cuff could restore near-native biomechanics and potentially reduce the risk of rotator cuff repair failure. PMID- 30285461 TI - Milk-Derived Exosomes and Metabolic Regulation. AB - Exosomes are natural nanoparticles that play an important role in cell-to-cell communication. Communication is achieved through the transfer of cargos, such as microRNAs, from donor to recipient cells and binding of exosomes to cell surface receptors. Exosomes and their cargos are also obtained from dietary sources, such as milk. Exosome and cell glycoproteins are crucial for intestinal uptake. A large fraction of milk exosomes accumulates in the brain, whereas the tissue distribution of microRNA cargos varies among distinct species of microRNA. The fraction of milk exosomes that escapes absorption elicits changes in microbial communities in the gut. Dietary depletion of exosomes and their cargos causes a loss of circulating microRNAs and elicits phenotypes such as loss of cognitive performance, increase in purine metabolites, loss of fecundity, and changes in the immune response. Milk exosomes meet the definition of bioactive food compounds. Expected final online publication date for the Annual Review of Animal Biosciences Volume 7 is February 15, 2019.

AB - Hepatitis E virus (HEV) is an important human pathogen that historically has been difficult to study. Limited levels of replication in vitro hindered our understanding of the viral life cycle. Sporadic and low-level virus shedding, lack of standardized detection methods, and subclinical infections made the development of animal models difficult. Better diagnostic techniques and understanding of the virus increased our ability to identify and characterize animal strains and animals that are amenable to model human-relevant infection. These advances are translating into the development of useful HEV animal models so that some of the greatest concerns associated with HEV infection, including host immunology, chronic infection, severe pregnancy mortality, and extrahepatic manifestations, can now be studied. Continued development of these animal models will be instrumental in understanding the many complex questions associated with HEV infection and for assessing therapeutics and prevention strategies to minimize HEV becoming a greater risk to the human population.

PMID- 30285463 TI - Acetabular Labral Reconstruction: Development of a Tool to Predict Outcomes. AB - BACKGROUND:: Acetabular labral reconstruction has demonstrated good results for labral lesions not amenable to labral repair. PURPOSE:: To determine the predictors of outcomes at a minimum 2 years after labral reconstruction. STUDY DESIGN:: Case series; Level of evidence, 4. METHODS:: Patients included in the study underwent labral reconstruction with a minimum 2-year follow-up. The primary outcome variable was the Hip Outcome Score-Activities of Daily Living (HOS-ADL). Secondary outcome measures included the 12-item Short Form Health Survey physical component summary (SF-12 PCS) and patient satisfaction with surgical outcomes. Preoperative and intraoperative variables assessed included demographics, prior surgery, chronicity of symptoms, radiographic measurements, preoperative outcome scores, and findings at arthroscopic surgery. Predictors were assessed using logistic regression with restricted cubic splines. Bivariate statistics assessed risk factors for reoperation including revision arthroscopic surgery and total hip arthroplasty (THA). RESULTS:: Three hundred seventeen of 368 labral reconstructions were available for follow-up (86.1%). Of these, 42 were converted to THA (13.2%) and 35 required revision arthroscopic surgery after labral reconstruction (11.0%). Factors associated with THA included older age, >=2 previous surgeries, <=2 mm of joint space, and lateral center edge angle (LCEA) <25 degrees . Factors associated with revision included female sex, >=2 previous surgeries, and LCEA <25 degrees . Six patients refused to participate (1.9%), leaving 234 with a minimum follow-up of 2 years (mean, 3.7 years [range, 2.0-11.3 years]). These patients had significant improvement in HOS-ADL (71 to 90; P < .001), HOS-Sport (47 to 75; P < .001), Western Ontario and McMaster Universities Osteoarthritis Index (27 to 9; P < .001), modified Harris Hip Score (65 to 85; P < .001), and SF-12 PCS scores (41.6 to 53.1; P < .001). Median postoperative satisfaction was 9. Predictors of improvement for the HOS-ADL included higher preoperative HOS-ADL scores ( P < .001), joint space >2 mm ( P = .004), and no prior surgery ( P = .039). Predictors of improvement for the SF-12 PCS included higher preoperative SF-12 PCS scores ( P < .001), subacute chronicity (3 months to 1 year) of symptoms ( P = .013), and joint space >2 mm ( P = .046). Joint space >2 mm ( P < .001) and higher preoperative SF-12 scores (PCS: P = .034; mental component summary: P = .039) predicted higher satisfaction. CONCLUSION:: At a minimum 2 years' follow-up, patients who did not undergo conversion to THA (13.2%) or require revision (11.0%), reported significant improvement in outcome scores and high satisfaction with outcomes. Predictors of revision or THA included >=2 previous surgeries, low LCEA, female sex for revision, and narrowed joint space for THA. Higher preoperative outcome scores were the most significant predictors of improvement after labral reconstruction. Lower preoperative scores, joint space narrowing, and history of surgery were predictive of an inferior result and decreased postoperative satisfaction.

AB - Fenestrations are pores within liver sinusoidal endothelial cells (LSECs) that enable the transfer of substrates (particularly insulin and lipoproteins) between blood and hepatocytes. With increasing age there are marked reductions in the frequency and diameter of fenestrations, referred to as pseudocapillarization. Currently, fenestrations are thought to be regulated by VEGF and NO pathways promoting remodelling of the actin cytoskeleton and cell membrane lipid rafts. We investigated the effects of drugs that act on these pathways on fenestrations in old (18-24m) and young mice (3-4m). Isolated LSECs were incubated with either: cytochalasin D, 7-ketocholesterol, sildenafil, amlodipine, simvastatin, 2, 5 dimethoxy-4-iodoamphetamine (DOI), bosentan, TNF-related apoptosis-inducing ligand (TRAIL) or nicotinamide mononucleotide (NMN). LSECs were visualized under scanning electron microscopy to quantify fenestration porosity, diameter and frequency; and direct stochastic optical reconstruction microscopy to examine actin and NO synthase. In young and old LSECs, fenestration porosity, diameter and frequency were increased by 7-ketocholesterol; while porosity and/or frequency were increased with NMN, sildenafil, amlodipine, TRAIL and cytochalasin D. In old mice only, bosentan and DOI increased fenestration porosity and/or frequency. Modification of the actin cytoskeleton was observed with all agents that increased fenestrations, while NO synthase was only increased by sildenafil, amlodipine and TRAIL. In conclusion agents that target NO, actin or lipid rafts promote changes in fenestrations in mice LSECs. Regulation of fenestrations occurs via both NO-dependent and independent pathways. This work indicates that age-related defenestration can be reversed pharmacologically which has potential translational relevance for dyslipidaemia and insulin resistance. PMID- 30285465 TI - SEPIAPTERIN, ALLEVIATES IMPAIRED GASTRIC nNOS FUNCTION IN SPONTANEOUS DIABETIC FEMALE RODENTS THROUGH NRF2 mRNA TURNOVER and miRNA BIOGENESIS PATHWAY. AB - An impaired nitrergic system and altered redox signaling contribute to gastric dysmotility in diabetics. Our earlier studies show that NF-E2-related factor 2 (NRF2) and Phase II antioxidant enzymes play a vital role in gastric neuronal nitric oxide synthase (nNOS) function. This study aims to investigate whether supplementation of sepiapterin (SEP), a precursor for BH4 (a cofactor of NOS) via salvage pathway, restores altered nitrergic systems and redox balance in spontaneous diabetic (DB) female rats. Twelve-week spontaneous DB and age matched, non-DB rats, with and without dietary SEP (daily 20 mg/kg body weight for 10 days) treatment, were used in this study. Gastric antrum muscular tissues were excised to investigate the effects of SEP in nitrergic relaxation and the nNOS-NO-NRF2 pathway(s). Dietary SEP supplementation significantly (p<0.05) reverted diabetes-induced changes in nNOS dimerization and function; nitric oxide (NO) downstream signaling molecules; HSP-90, a key regulator of nNOSalpha activity and dimerization; miRNA-28 that targets NRF2 messenger RNA (mRNA) and levels of microRNA (miRNA) biogenesis pathway components, such as DGCR8 (DiGeorge Syndrome Critical Region Gene 8) and TRBP (HIV1-1 transactivating response [TAR] RNA-binding protein). These findings emphasize the importance of the BH4 pathway in regulating gastric motility functions in DB animals by modulating nNOSalpha dimerization in association with changes in enteric NRF2 and NO downstream signaling. Our results also identify a new pathway, wherein SEP regulates NRF2 mRNA turnover by suppressing elevated miRNA-28, which could be related to alterations in miRNA biogenesis pathway components. PMID- 30285466 TI - Knockout of ClC-2 reveals critical functions of adherens junctions in colonic homeostasis and tumorigenicity. AB - BACKGROUND & AIMS: Adherens junctions (AJs), together with tight junctions (TJs), form an apical junctional complex that regulates intestinal epithelial cell-to cell adherence and barrier homeostasis. Within the AJ, membrane-bound E-cadherin binds beta-catenin, which functions as an essential intracellular signaling molecule. We have previously identified a novel protein in the region of the apical junction complex, chloride channel protein 2 (ClC-2), which we have used to study TJ regulation. In this study, we investigated the possible effects of ClC-2 on the regulation of AJs in intestinal mucosal epithelial homeostasis and tumorigenicity. METHODS: Mucosal homeostasis and junctional proteins were examined in wild type (WT) and ClC-2 knockout (KO) mice as well as associated colonoids. Tumorigenicity and AJ-associated signaling were evaluated in a murine colitis-associated tumor model and in a colorectal cancer cell line (HT-29). RESULTS: Colonic tissues from ClC-2 KO mice had altered ultrastructural morphology of intercellular junctions with reduced colonocyte differentiation, whereas jejunal tissues had minimal changes. Colonic crypts from ClC-2 KO mice had significantly higher numbers of less-differentiated forms of colonoids as compared to WT. Furthermore, the absence of ClC-2 resulted in redistribution of AJ proteins and increased beta-catenin activity. Downregulation of ClC-2 in colorectal cells resulted in significant increases in proliferation associated with disruption of AJs. Colitis-associated tumors in ClC-2 KO mice were significantly increased, associated with beta-catenin transcription factor activation. CONCLUSION: The absence of ClC-2 results in less differentiated colonic crypts and increased tumorigenicity associated with colitis via dysregulation of AJ proteins and activation of beta-catenin-associated signaling. PMID- 30285467 TI - Chromatographic Methods for the Determination of Emerging Contaminants in Natural Water and Wastewater Samples: A Review. AB - This review is devoted to analytical methods published in the scientific literature in the last 10 years for the determination of emerging contaminants in aquatic media. The article is mainly focused on sample preparation and on instrumental techniques most used for the detection and quantification of the analytes of interest. The sample preparation techniques include classical liquid liquid extraction and solid-phase extraction, but also recent microextraction techniques such as solid-phase microextraction, stir-bar sorptive extraction, dispersive liquid-liquid microextraction, ultrasound-assisted emulsification microextraction, or microextraction by packed sorbent. Most studies focus on minimizing the number of analysis steps and on the use of the lowest amount of solvents in the sample treatment step. Liquid chromatography and gas chromatography mainly coupled to tandem mass spectrometry are usually the employed analytical techniques. A large number of multiresidue methods are being developed for the determination of several families of these compounds with only one extraction step to minimize sample handling and treatment. PMID- 30285468 TI - Novel technologies in utilization of byproducts of animal food processing: a review. AB - China is one of the countries with most abundant livestock and poultry resources in the world. The average annual growth rate of output value of livestock and poultry industry reaches 13%, and the output value of livestock and poultry industry accounts for more than 35% of total agricultural output. A large number of byproducts are produced in animal slaughtering and processing operations. If livestock and poultry byproducts are effectively utilized, this will make a huge contribution to GDP. At the same time, aquaculture is China's pillar industry. During fish processing, a large number of byproducts (including fish heads, fish skins, fish bones, fish scales, and viscera) are produced, which weighs approximately 40-55% of the raw fish. The byproducts of freshwater fish are more than 2.5 million tons per annum, most of which are not used. The effective use of byproducts has a direct influence on China's economic and environmental pollution. The nonuse or underutilization of byproducts not only leads to loss of potential revenue, but also results in to an increase in these products and their disposal costs. This paper makes a comprehensive review of the research progress of animal byproduct utilization to date, and aims to provide reference for the utilization and research of animal byproducts. PMID- 30285469 TI - Diagnostic ultrasound assessment of temporomandibular joints: a systematic review and meta-analysis. AB - OBJECTIVES:: The purpose of this systematic review was to determine the diagnostic capability of ultrasound to assess TMJ alterations as disc displacement (DD), joint effusion (JE) and condylar changes (CC) using 3D imaging modalities as reference standard. METHODS:: Studies were gathered by searching several electronic databases and partial grey literature up to January eighth, 2018 without restrictions of language and time. The risk of bias was evaluated using the second version of Quality Assessment Tool for Diagnostic of Accuracy Studies-2 (QUADAS-2). The grading of Recommendation, Assessment, Development and Evaluation (GRADEpro system) instrument was applied to assess the level of evidence across the studies. RESULTS:: After applying the eligibility criteria, 28 studies were identified and synthesized. All studies were methodologically acceptable presenting low applicability concerns, although none of them fulfilled all QUADAS-2 criteria. The quantitative analysis included 22 studies, 2829 joints in total. The quality of the evidence evaluated by GRADE system suggested moderate confidence in estimating the outcomes. CONCLUSION:: This systematic review demonstrated the ultrasound has acceptable capability to screen for DD and JE in TMD patients. For screening of condylar changes, ultrasound needs further studies using CT or CBCT as reference standard to support its use. More advanced imaging such as MRI can thereafter be used to confirm the diagnosis if deemed necessary.

PMID- 30285471 TI - Factors That Modify the Association of Maternal Postpartum Smoking and Exclusive Breastfeeding Rates. AB - BACKGROUND AND OBJECTIVE: Maternal postpartum smoking increases the risk for poor infant health outcomes, while exclusive breastfeeding has been shown to support infant health. Limited population-based research has been published on the interaction between maternal smoking and exclusive breastfeeding. The objective of this study was to examine factors modifying the association between maternal postpartum smoking and exclusive breastfeeding among women in the United States. METHODS: Secondary data analysis was conducted using the 2009-2011 Pregnancy Risk Assessment Monitoring System. Stratified analyses were used to examine the associations between maternal postpartum smoking and exclusive breastfeeding by sociodemographic factors. RESULTS: The postpartum smoking rate was 17.1%. The relationship between postpartum smoking and exclusive breastfeeding at 12 weeks varied by maternal education level, race/ethnicity, Medicaid use, and pregestational or gestational diabetes. The magnitude of reduction in the odds of exclusive breastfeeding at 12 weeks postpartum among the women who smoked in the postpartum period ranges from odds ratio (95% confidence interval) 0.52 (0.37 0.74) for non-Hispanic blacks to 0.31 (0.22-0.43) for women who had <12 years of education. CONCLUSIONS: Women who smoked in the postpartum period, who also suffered from socioeconomic disadvantages, had a higher likelihood of not continuing exclusive breastfeeding. Identification of women at high risk for not exclusively breastfeeding is important for targeting populations in need of appropriate and timely support for prenatal and postpartum smoking cessation and breastfeeding promotion.

AB - 3D printing, also referred to as additive manufacturing, offers a wide range of new processing possibilities to the food industry. This technology allows a layer by layer (bottom to top) printing of predefined slices of designed and desired objects. 3D printing potentially allows rapid manufacturing of complex objects, which are unhindered by design complexity, thus providing substantial liberty to create new and untested geometric shapes. In terms of food manufacturing, the potential that 3D food printing technologies can bring may revolutionize certain aspects of food manufacturing, providing the convenience of low-cost customized fabrication and even tailored nutrition control. The most common materials suitable for 3D food printing are carbohydrate, fat, protein, fiber and functional components. In the present study, the characteristics of raw materials or additives used during 3D printing, and requirements for estimating and improving their printing performance and self-supporting ability in extrusion based printing regarding rheological characteristics of 3D food printing materials are reviewed. As an innovative process, 3D food printing may induce a revolution in certain areas of food manufacturing.

PMID- 30285473 TI - Methods of extraction, separation, purification, structural characterization for polysaccharides from aquatic animals and their major pharmacological activities. AB - The further development of fishery resources is a hotspot in the development of the fishery industry. However, how to develop aquatic animal resources deeply is a key point to be solved in the fishery industry. Over the past decades, numerous aquatic animals have gained great attention in the development and utilization of their bioactive molecules which are of therapeutic applications as nutraceuticals and pharmaceuticals. Recent research revealed that aquatic animals are composed of many vital moieties, such as polysaccharides and proteins, which provide health benefits beyond basic nutrition. In particular, aquatic animal polysaccharides are gaining worldwide popularity owing to their high content, ease of extraction, specific structure, few side effects, prominent therapeutic potential and incorporation in functional foods and dietary supplements. Thus, tremendous research on the isolation, identification and bioactivities of polysaccharides has been carried out. This review presents comprehensive viewpoints on extraction, separation, purification, structural characterization and bioactivity of various polysaccharides from aquatic animals, such as sea cucumber, abalone, oyster and mussels. In addition, this review profiled a brief knowledge on both current challenges and future scope in aquatic animal polysaccharides field. The review will be a direction of deep processing in fishery resources, which is a hotspot, but technical bottleneck. Furthermore, the review could be served as a useful reference material for further investigation, production and application of polysaccharides from aquatic animals in functional foods and therapeutic agents. PMID- 30285475 TI - Cheesomics: the future pathway to understanding cheese flavour and quality. AB - Cheese is a fermented dairy product, harboring diverse microbial communities (microbiota) that change over time and vary depending on the type of cheese and their respective starter and adjunct cultures. These microorganisms play a crucial role in determining the flavor, quality and safety of the final product. Exploring the composition of cheese microbiota and the underlying molecular mechanisms involved in cheese ripening has been the subject of many studies. Recent advances in next generation sequencing (NGS) methods and the development of sophisticated bioinformatics tools have provided deeper insights into the composition and potential functionality of cheese microbiota far beyond the information provided by culture-dependent methods. These advances, which include rRNA gene amplicon sequencing and metagenomics, have been complemented and expanded in recent years by the application of metatranscriptomics, metaproteomics and metabolomics. This paper reviews studies in which application of these meta-omics technologies has led to a better understanding of the microbial composition and functionality of cheese and highlights opportunities by which the integration of outputs from diverse multi-omics analytical platforms (cheesomics) could be used in the future to advance our knowledge of the cheese ripening process and identify biomarkers for predicting cheese flavor, quality, texture and safety, and bioactive metabolites with potential to influence human health. PMID- 30285476 TI - Excellent Glycemic Control Maintained by Open-Source Hybrid Closed-Loop AndroidAPS During and After Sustained Physical Activity. AB - OBJECTIVE: Officially licensed hybrid closed-loop systems are not currently available worldwide; therefore, open-source systems have become increasingly popular. Our aim was to assess the safety, feasibility, and efficacy of an open source hybrid closed-loop system (AndroidAPS) versus SmartGuard(r) technology for day-and-night glucose control in children under extreme sports conditions. RESEARCH DESIGN AND METHODS: Twenty-two children (16 girls, 6-15 years of age, median HbA1c 56 +/- 9 mmol/mol) were enrolled in this pivotal winter sports camp study. The participants were divided into two groups using either the AndroidAPS or SmartGuard technology. Physical exertion was represented by all-day alpine skiing. The primary endpoints were mean glucose level, time below the threshold of 3.9 mmol/L, and time within the target range of 3.9 to 10 mmol/L. RESULTS: The children using the AndroidAPS had significantly lower mean glycemia levels (7.2 +/- 2.7 vs. 7.7 +/- 2.8 mmol/L; 129.6 +/- 49 vs. 138.6 +/- 50 mg/dL, P < 0.042) than the children using the SmartGuard. The proportion of time below the target (median 5.0% +/- 2.5% vs. 3.0% +/- 2.3%, P = 0.6) and in the target zone (63% +/- 9.5% vs. 63% +/- 18%, P = 0.5) did not significantly differ. The AndroidAPS group experienced more frequent malfunctions of the cannula set (median 0.8 +/- 0.4 vs. 0.2 +/- 0.4, P = 0.02), which could have affected the results. No significant difference was found in the amount of carbohydrates consumed for the prevention and treatment of hypoglycemia [median 40 +/- 23 vs. 25 +/- 29 g/(patient .3 days)]. No episodes of severe hypoglycemia or other serious adverse events were noted. CONCLUSIONS: This pilot study showed that the AndroidAPS system was a safe and feasible alternative to the SmartGuard Technology.

PMID- 30285479 TI - Potentiometry as a Tool for Monitoring of Antioxidant Activity and Oxidative Stress Estimation in Medicine. AB - The complexity of biological objects and the rapid change in their composition after sampling, the variety of compounds of different chemical nature, possessing oxidative and antioxidant properties, make the task of its estimating extremely nontrivial and important for food, nutrients and human health characterization. The paper discusses the use of potentiometry in determining integral antioxidant/oxidant activity mainly of biological fluids and human skin. The source of information is the electrode potential shift that occurs when the analyzed object is inserted in the solution of the mediator system or when the mediator system is exposed to human skin. The experimental approaches, protocols, calculations are described. A number of examples of antioxidant activity and oxidative stress estimation in medicine are presented. The works show lower levels of antioxidant activity (AOA) of plasma and blood serum in patients with cardiovascular diseases, obesity, and malignant neoplasms as compared with the healthy volunteers. It was found out that antioxidant activity of fertile men semen is higher than AOA of infertile patients. Using the method discussed have shown that in some infertile male patients antioxidant activity of semen has been accompanied by oxidant activity. It has been found, that antioxidant activity of skin increases after intake of ascorbic acid and vitamin-enriched juices. The described approach holds considerable promise for monitoring oxidative stress of the whole organism and its systems, and for selecting effective and safe therapy. Thus, it opens up new opportunities in expanding the use of analytical chemistry in such an important field as medicine. PMID- 30285480 TI - Liquid Crystals in Analytical Chemistry: A Review. AB - Nearing 130 years since their introduction, liquid crystals (LCs) have found diverse applications in different fields of science, including chemical analysis. This review encompasses the history of LCs, reviews various types of them, and presents their current applications in analytical chemistry. Since most applications of LCs in analytical chemistry are for the fabrication of biosensors, these applications are discussed first. The high sensitivity of LCs to changes in their environment makes them ideal for such sensors. Using them, analyte concentrations as low as 1 pM have been detected. Another major application of LCs is in gas chromatography (GC) as stationary phases, which is described in the second part of this review. Using LCs in GC leads to better separations, higher sensitivity, and improved selectivity. Such phases provide higher stability in elevated temperatures and increased column life times. Finally, applications of LCs in electro-analytical chemistry will be described briefly.

PMID- 30285481 TI - Enterotoxigenic Escherichia coli (ETEC) heat labile enterotoxin inhibits intestinal ascorbic acid uptake via a cAMP-dependent NF-kappaB mediated pathway. AB - Vitamin C is an antioxidant and acts as a cofactor for many enzymatic reactions. Humans obtain vitamin C from dietary sources via intestinal absorption, a process that involves the sodium dependent vitamin C transporters-1 and -2 (SVCT1 and SVCT2). Enterotoxigenic Escherichia coli (ETEC) infection impacts intestinal absorption/secretory functions but nothing is known about its effect on ascorbic acid (AA) uptake. Here we demonstrate that infection of Caco-2 cells with ETEC led to a significant inhibition in intestinal AA uptake. This inhibition was associated with a marked reduction in hSVCT1 and hSVCT2 protein, mRNA and hnRNA expression levels as well as significant inhibition in the activity of both the SLC23A1 and SLC23A2 promoters. Similarly, exposure of mice to ETEC led to a significant inhibition in intestinal AA uptake and reduction in mSVCT1 and mSVCT2 protein, mRNA and heterogeneous nuclear RNA (hnRNA) expression levels. Inhibition was caused by the action of heat labile enterotoxin (LT), as infecting Caco-2 cells with LT-deficient ETEC (DeltaLT) failed to impact on AA uptake. Since LT activates adenylate cyclase we also examined the effect of dibutyryl-cAMP in AA uptake by Caco-2 cells and observed a significant inhibition. Furthermore, treating the cells with celastrol, a specific NF-kappaB inhibitor, significantly blocked the inhibition of AA uptake caused by ETEC infection. Together, these data demonstrate that ETEC infection impairs intestinal AA uptake through a cAMP dependent NF-kappaB mediated pathway that regulates both SLC23A1 and SLC23A2 transcription.

AB - PURPOSE: This quality improvement, educational intervention project aimed to develop nurse leaders at a large urban federally funded Health Care for the Homeless Program (HCH), using the Nursing Leadership Institute Competency Model. METHODS: A leadership seminar series which addressed six leadership topics for homeless health care nurses was developed, implemented, and evaluated using a one group pre/posttest design. The Leadership Practices Inventory (LPI) was also administered before and after the seminar series. RESULTS: There were statistically significant increases in new skills in the areas of interpersonal skills, personal mastery, systems thinking, and finance management. LPI scores improved after completion of the leadership seminar series. CONCLUSION: Participation in the leadership seminar series improved leadership skills and competencies of nurse leaders at the HCH. The acquired new knowledge may prepare homeless health nurses for sustained leadership roles which in turn will result in better meeting the needs of organizations providing care to homeless individuals.

Discrimination by health care professionals is a major deterrent for LGBTQ individuals to seek health care. The purpose of the article is to offer practice recommendations using targeted community actions to enhance LGBTQ cultural sensitivity in community health care settings. Strategic planning, assessment for readiness to change, environmental strengths, weaknesses, opportunities, and threats analysis, and use of community resources are recommended as part of a basic model for change in a community setting. Outcomes are measured using a cultural competency tool. PMID- 30285488 TI - Engaging Nursing Students in a Rural Native American Community to Facilitate Cultural Consciousness. AB - Integrating cultural consciousness into nursing curricula is important for preparing a global nursing workforce. This article evaluated the impact of a teaching strategy designed to facilitate nursing students' cultural consciousness beyond the classroom during a 1-week field experience within a rurally isolated Native American community. Cultural consciousness health care is a central element of health care delivery that integrates clinical knowledge, sensitivity, and cultural understanding. This study used an intrinsic single case study design bounded by 30 nursing students' perceptions of their week-long immersion experience within a rurally isolated American Indian community. The reality of the situations they encountered did not match their expressed expectations nor their tacit assumptions. Evidence taken in situ from clinical reflections demonstrated most of the students wrestled with this mismatch, although they improved their clinical assessment, technical nursing, and intercultural communication skills. Evidence from end of course reflections demonstrated that two-thirds of the students integrated their preconceptions and their immersion experiences with cultural consciousness emerging in their reflections. PMID- 30285489 TI - The impact of morphophonological patterns on verb production: evidence from acquired morphological impairment. AB - Although much of the research on morphology and aphasia has focused specifically on the distinction between regular and irregular verb production, individuals with aphasia often present with differences in performance within these categories. While these within-category differences are relatively understudied, they have the potential to inform our understanding of the morphological processing system and treatment protocols for morphological impairment. The present study examines how morphophonological patterns in English impact past tense production within the categories of regular and irregular verbs based on errors of an individual with acquired morphological impairment. Acquired morphological impairment was demonstrated by performance on two reading tasks. First, the individual produced more final consonant deletion errors in morphologically complex words (prays->[pre]) compared to homophones (praise >[pre]). Second, morphological deletion errors were found to occur at comparable rates for inflected regular verbs (sinned->sin) and inflected irregular verbs (won->win), whereas the analogous error (e.g. ton->tin) never occurred on the monomorphemic pairs. In order to examine differences within each category, we used a past-tense elicitation task designed to analyse the effect of differences in morphophonological pattern frequency on accuracy and error patterns in production. We found production of both regular and irregular verbs was affected by the extent to which different morphophonological patterns are supported in the language (i.e. the number of phonologically similar words within the lexicon which take the same inflectional change). These results provide evidence that morphophonological patterns are encoded in a way that impact morphological production, a finding which has both clinical and theoretical implications. PMID- 30285490 TI - Epigenetics in Insects: Genome Regulation and the Generation of Phenotypic Diversity. AB - Epigenetic inheritance is fundamentally important to cellular differentiation and developmental plasticity. In this review, we provide an introduction to the field of molecular epigenetics in insects. Epigenetic information is passed across cell divisions through the methylation of DNA, the modification of histone proteins, and the activity of noncoding RNAs. Much of our knowledge of insect epigenetics has been gleaned from a few model species. However, more studies of epigenetic information in traditionally nonmodel taxa will help advance our understanding of the developmental and evolutionary significance of epigenetic inheritance in insects. To this end, we also provide a brief overview of techniques for profiling and perturbing individual facets of the epigenome. Doing so in diverse cellular, developmental, and taxonomic contexts will collectively help shed new light on how genome regulation results in the generation of diversity in insect form and function.

PMID- 30285491 TI - Biology and Control of the Khapra Beetle, Trogoderma granarium, a Major Quarantine Threat to Global Food Security. AB - The khapra beetle, Trogoderma granarium, is a voracious feeder of stored products and is considered one of the most important quarantine pests globally. Its ability to survive for long periods under extreme conditions facilitates its spread through international commerce, which has led to invasions of new geographic regions. The khapra beetle is an important quarantine pest for many countries, including the major wheat-producing countries the United States, Canada, Russia, and Australia, and has been classified as one of the 100 worst invasive species worldwide. This species cannot always be controlled by insecticides and other nonchemical methods that are usually effective against other pests of stored products, particularly owing to its diapausing late larval stage. It can rapidly develop at elevated temperatures and under dry conditions, which are not favorable for many major stored-product insects. We synthesize key published work to draw attention to advances in biology, detection and control of the khapra beetle, and directions to consider for future research. Expected final online publication date for the Annual Review of Entomology Volume 64 is January 7, 2019. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates. PMID- 30285492 TI - Management of multiple myeloma bone disease: impact of treatment on renal function. AB - INTRODUCTION: Bone disease (BD) is one of the most common features of multiple myeloma. Seventy to eighty percent of patients at diagnosis present with lytic lesions which may lead to skeletal-related events. Areas covered: The aim of this review is to present the possible adverse profile of bisphosphonates (BPs) on renal function, the underlying mechanisms by which BPs may affect renal function and the novel therapeutic approaches on myeloma bone disease management. Expert commentary: BPs remain the cornerstone in the management of myeloma-related BD. Zoledronic acid and Pamidronate are currently the gold standard, however cannot be used in patients with severe renal dysfunction. Renal impairment is another hallmark of myeloma with approximately 60% of the patients presenting with or developing renal dysfunction during the disease course. Although BPs rarely cause renal impairment, they should be administered with caution in patients with impaired renal function. The exact mechanism by which BPs cause renal impairment is yet to be elucidated. Another promising agent is denosumab, a RANKL inhibitor, which can be administrated regardless of renal function and does not need the relevant dose-adjustments.

AB - OBJECTIVE: We studied which games and underlying game mechanics are considered motivating by older adults, so that designers and therapists make informed choices when designing or selecting virtual reality (VR)-training interventions. MATERIALS AND METHODS: We conducted a repeated measures design with 30 older participants, who played eight different VR-training games and afterward filled out the intrinsic motivation inventory (IMI). Differences in intrinsic motivation between games were analyzed using Friedman's tests. In addition, in-depth interviews were conducted according to the laddering technique, to unveil the underlying game mechanics that lead to the players preferences. RESULTS: IMI scores were relatively high for all games, indicating that these VR games seem effective for inducing a high intrinsic motivation. Wii yoga and Kinect Adventures were the highest scoring games on all but the negative subscale tension. Both games provided regular positive feedback. An important game mechanic was Variation, which showed a strong link to important values such as: to Stay Focused, Improve Fitness, and Health and Independency. Furthermore, the game mechanics Visual Feedback and Positive Feedback, which lead to an increased Drive to Perform, were perceived valuable. Seemingly contradicting, but both important attributes such as Speed versus Slow Movements emphasize the importance of designing VR training that adapts to the skill level of the player. CONCLUSION: We have shown that games with different game mechanics can induce high intrinsic motivation. When designing or selecting VR balance training games for older adults, these game mechanics should be incorporated to optimize a positive user experience and increase intrinsic motivation. PMID- 30285494 TI - Associations between distress tolerance and asthma symptoms and quality of life. AB - OBJECTIVE: Given the robust associations between anxiety and asthma, the purpose of the current study was to explore associations between asthma outcomes and tolerance for negative affective states (i.e. distress tolerance) as well as tolerance for the specific negative emotional states of anxiety and fear. METHODS: Participants were 61 nonsmoking adults with asthma (61.9% female, 54.8% African-American, Mage = 34.72, SD = 13.58) who underwent spirometry and completed self-report measures. RESULTS: After controlling for the effects of age, race and the physical concerns domain of anxiety sensitivity, poorer global distress tolerance and tolerance for fear and anxiety each significantly predicted poorer lung function (8.7-13.8% variance), asthma control (4.9-8.8% variance) and asthma-related quality of life (6.7-8.9%). CONCLUSIONS: These findings suggest that targeting distress tolerance, specifically tolerance of fear and anxiety, may be helpful in improving asthma outcomes.

PMID- 30285496 TI - On the Road to Breeding 4.0: Unraveling the Good, the Bad, and the Boring of Crop Quantitative Genomics. AB - Understanding the quantitative genetics of crops has been and will continue to be central to maintaining and improving global food security. We outline four stages that plant breeding either has already achieved or will probably soon achieve. Top-of-the-line breeding programs are currently in Breeding 3.0, where inexpensive, genome-wide data coupled with powerful algorithms allow us to start breeding on predicted instead of measured phenotypes. We focus on three major questions that must be answered to move from current Breeding 3.0 practices to Breeding 4.0: ( a) How do we adapt crops to better fit agricultural environments? ( b) What is the nature of the diversity upon which breeding can act? ( c) How do we deal with deleterious variants? Answering these questions and then translating them to actual gains for farmers will be a significant part of achieving global food security in the twenty-first century. PMID- 30285497 TI - A qualitative study of parent perspectives on barriers, facilitators and expectations for school asthma care among urban, African-American children. AB - OBJECTIVES: Minority children experience the disproportionate burden of asthma and its consequences. Studies suggest ethnic groups may experience asthma differently with varied perceptions and expectations among parents of African American and Latino children. Because parents coordinate asthma care with the school, where children spend a significant amount of their day, this study's goal was to determine parents' perspectives on school asthma management. METHODS: Focus groups were conducted with parents of children with asthma at four urban schools whose student population is predominantly African-American. A semi structured guide was utilized focusing on barriers, facilitators and expectations for asthma care at school. Grounded theory principles were applied in this study. RESULTS: Twenty-two parents (91% females) representing 13 elementary and 10 middle school children with asthma (61% boys) participated in four focus groups. Most children (87%) had persistent asthma. The identified barriers to effective school-based asthma care included limited awareness of children with asthma by teachers/staff, communication issues (e.g. school/parent, within school), inadequate education and lack of management plans or systems in place. In contrast, the identified facilitators included steps that fostered education, communication and awareness, as supported by management plans and parent initiative. Parents described their expectations for increased communication and education about asthma, better systems for identifying children with asthma, and a trained asthma point person for school-based asthma care. CONCLUSIONS: Parents of children with asthma identified important barriers, facilitators and expectations that must be considered to advance school asthma management. Improved school-based asthma care could lead to better health and academic outcomes. PMID- 30285498 TI - Health beliefs associated with poor disease self-management in smokers with asthma and/or COPD: a pilot study. AB - BACKGROUND: Compared to nonsmokers, smokers with chronic disease are less likely to adhere to self-management recommendations for the management of their chronic conditions. Although the literature notes poor adherence trends in smokers, actual influences of adherence in these patients require further study. This study examines the health beliefs that influence self-management behaviors in smokers with chronic lung disease. METHODS: This prospective, cross-sectional study surveyed patients (n = 83) seen in the pulmonary outpatient clinics of the University Medical Center of New Orleans between November 2015 and February 2016. Eligible patients included those between 40-64 years old diagnosed with asthma and/or chronic obstructive pulmonary disease (COPD). Primary measures included perceived beliefs related to the susceptibility to asthma and/or COPD becoming worse, perceived barriers to adherence, and perceived benefits to adherence. Patient characteristics under-study included smoking status, race, gender, and diagnosis. Descriptive and chi-square analyses were performed to characterize the sample. Student's t and and regression analyses were conducted to examine the relationships between perceptions, smoking status, race, gender, and diagnosis. RESULTS: Compared to nonsmokers, smokers perceived their asthma and/or COPD becoming worse (p = 0.0023). Smokers also perceived more barriers (p < 0.0001), and fewer benefits to adherence than nonsmokers (p = 0.0021). CONCLUSION: The health beliefs of smokers may influence their self-management behaviors. Results of this study can inform the development of services that target smokers in order to improve adherence to self-management behaviors and health outcomes. PMID- 30285499 TI - Filling the patient-provider knowledge gap: a patient advocate to address asthma care and self-management barriers. AB - INTRODUCTION: In an ongoing study, a new clinical role adapted from a patient navigator called the patient advocate (PA) met with patients before medical visits, attended appointments and afterwards reviewed provider instructions. This qualitative analysis examines the perspectives of PAs and providers regarding their experiences with patients to understand how a PA can help patients and providers achieve better asthma control. METHODS: PAs recorded journal entries about their experiences with patients. Provider focus groups and interviews were conducted by researchers and transcribed. Analysis was based on the Grounded Theory approach for qualitative research, using open and then focused coding. Two researchers independently coded these sources until intercoder agreement was achieved. RESULTS: Upon review of 31 journal entries on PA experiences with 24 patients and transcripts from 2 provider focus groups and 12 provider interviews, 5 themes emerged surrounding asthma care and self-management: medication adherence, follow-up, communication, social determinants of health and time. While patients shared with PAs specific socioeconomic barriers to medication adherence and follow-up, providers often did not know about these problems and cited barriers to communication. Time restrictions on medical visits further limited communication. CONCLUSIONS: Perspectives reported here illustrate a gap in knowledge and understanding between patients and providers. The PA's unique relationship with patients and presence inside and outside of medical visits allowed them to learn contextual patient information unknown to providers. PAs and providers cited numerous ways PAs can help to improve patient-provider mutual understanding. PMID- 30285500 TI - Tofacitinib for the treatment of ulcerative colitis. AB - INTRODUCTION: New generations of small molecules are being developed for the treatment of ulcerative colitis. Among them, tofatinib (a Janus kinase (JAK) inhibitor) has demonstrated efficacy for inducing and maintaining remission and achieving mucosal healing with a reasonable safety profile. Oral administration is attractive for patients and lack of immunogenicity represents an advantage over biologic drugs. Areas covered: This review discusses the molecular aspects of the JAK-STAT pathway; the mechanism of action of tofacitinib pertinent to ulcerative colitis and the evidence on the efficacy of tofacitinib for achieving clinically relevant outcomes, including clinical remission, mucosal healing, and normalization of quality of life, as well as safety aspects with special attention to adverse events related to the mode of action of the drug. Expert commentary: Tofacitinib will be the first drug on the class of JAK inhibitors to be available for treatment of ulcerative colitis. The efficacy of the drug, with a rapid onset of action even in cases of severe colitis, oral administration, and possibility to use the drug intermittently without generating immunogenicity, will bring about a redesign of current treatment paradigms for ulcerative colitis. PMID- 30285501 TI - The usefulness of listening social media for pharmacovigilance purposes: a systematic review. AB - INTRODUCTION: Social media mining could be a possible strategy to retrieve drug safety information. The mining of social media is a complex process under progressive evolution, falling into three broad categories: listening (safety data reporting), engaging (follow-up), and broadcasting (risk communication). This systematic review is aimed at evaluating the usefulness and quality of proto signals by social media listening. Areas covered: In this systematic search, performed according to MOOSE and PRISMA statements, we selected studies, published in MEDLINE, EMBASE, and Google Scholar until 31 December 2017, that listened at least one social media to identify proto-adverse drug events and proto-signals. Expert opinion: The selected 38 studies identified serious and unexpected proto-adverse drug events characterized by poorer information quality as compared with spontaneous reporting databases. This feature allows rarely the evaluation of causal relationships. Proto-signals identified by social media listening had the potential of anticipating pre-specified known signals in only six studies. Moreover, the personal perception of patients reported in social media could be used to implement effective risk communication strategies. However, signal detection in social media cannot be currently recommended for routine pharmacovigilance, due to logistic and technical issues. PMID- 30285503 TI - Acute Oral Ingestion of a Multi-ingredient Preworkout Supplement Increases Exercise Performance and Alters Postexercise Hormone Responses: A Randomized Crossover, Double-Blinded, Placebo-Controlled Trial. AB - Multi-ingredient preworkout supplements (MIPS) are marketed as a means to increase exercise performance. The purpose of this study was to determine the effect of a single serving of Bang Pre-Workout Master Blaster (BMB) on upper- and lower-body power output and local muscular endurance. Ten resistance-trained males participated in two exercise testing sessions consisting of the vertical jump (VJ), seated medicine ball throw (SMBT), and local muscular endurance tests for the bench press (BP) and leg extension (LE) exercises at 70% of one repetition maximum. Participants consumed placebo (PLA) or BMB 30 minutes prior to each exercise session. No difference between trials was observed for SMBT distance or BP repetitions. Vertical jump (p = .006) and LE repetitions (p = .014) were greater for the BMB trial compared with placebo. A significant interaction between trial and time was observed for insulin-like growth factor-1 (IGF-1; p = .044). Serum IGF-1 was significantly increased at both 30 PS (p = .004) and 30PX (p = .038) compared with BL for the BMB trial only. In conclusion, acute ingestion of BMB increased lower-body power and endurance as measured by the VJ and LE repetition tests, respectively, without altering hemodynamics. Furthermore, serum IGF-1 increased in response to acute exercise with BMB supplementation, but not with PLA. No differences in human growth hormone (HGH) or serum cortisol responses were observed between trials. PMID- 30285502 TI - Relationship between intra-operative vein graft treatment with DuraGraft(r) or saline and clinical outcomes after coronary artery bypass grafting. AB - BACKGROUND: Saphenous vein grafts (SVGs) remain the most often used conduits for coronary bypass grafting (CABG). Progressive intimal hyperplasia contributes to vein-graft disease and vein-graft failure (VGF). We compared the impact of intraoperative preservation of SVGs in a storage solution (DuraGraft(r)) versus heparinized saline on VGF-related outcomes after CABG. METHODS: From 1996 to 2004, 2436 patients underwent isolated CABG with >= 1 SVG. SVGs were consecutively treated with DuraGraft in 1036 patients (2001-2004) and heparinized saline in 1400 patients (1996-1999). Short- (< 30 days) and long-term (>= 1000 days) outcomes were assessed using repeat revascularization (primary end point), and major adverse cardiac events (MACE) consisting of the composite of death, nonfatal myocardial infarction, or repeat revascularization. RESULTS: Mean follow up in the DuraGraft group was 8.5 +/- 4.2 years and 9.9 +/- 5.6 years in controls. Short-term event rates were low and generally did not differ between groups. DuraGraft was associated with a 45% lower occurrence of nonfatal myocardial infarction after 1000 days (hazard ratio 0.55, 95% CI 0.41-0.74; P < 0.0001). There was 35% and 19% lower long-term risk for revascularization (HR 0.65, 95% CI 0.44-0.97; P = 0.037) and MACE (HR 0.81, 95% CI 0.70-0.94; P = 0.0051), respectively, after DuraGraft. Mortality was comparable between both groups at 1, 5, and 10 years. There was no statistically significant association between DuraGraft exposure and time to death starting at 30 or 1000 days (HR 0.91, 95% CI 0.76-1.09; P = 0.29). CONCLUSION: In this study, intraoperative treatment of SVGs with DuraGraft was associated with a lower risk of long-term adverse events suggesting that efficient intraoperative SVG treatment may reduce VGF-related complications post-CABG. These data warrant randomized clinical trials to validate these findings. PMID- 30285504 TI - Renal resistive index significantly increased in hypertensive children and it is independently related to the pulse pressure and left ventricular mass index. AB - BACKGROUND: To the best our knowledge there is no data in the literature related to changes in renal resistive index (RRI) values in children who have hypertension (HT). In this study, we aimed to investigate the changes of RRI values and it is usability in children with HT. METHODS: A total of 75 children; 48 with newly diagnosed HT and 27 healthy controls were included in the study. Routine history, physical examination, and laboratory examinations were performed. Left ventricular (LV) dimensions and systolic-diastolic functions, septum and posterior wall thickness (IVSd and PWd) and LV mass index (LVMI) were calculated by echocardiography. In addition to routine renal ultrasonography (US), renal pulsatility indexes (RPI), accelerated time and RRI were measured. Increased RRI was accepted as >0.70. RESULTS: Increased RRI was detected in 25 (52%) of HT patients. Systolic and diastolic blood pressure (SBP and DBP), and pulse pressure (PP), low-density lipoprotein cholesterol and triglyceride levels, RRI, RPI, kidney length, IVSd, PWd, and LVMI were significantly higher in patients with HT (both p < 0.05). SBP and PP, PWd, LV ejection fraction, LV fractional shortening, and LVMI were positively correlated with the RRI. High density lipoprotein cholesterol was negatively correlated with the RRI. Of these measurements, RRI values were found to be independently associated with PP and LVMI (p < 0.05). CONCLUSIONS: In hypertensive children, RRI was significantly higher than healthy controls and it is also related with LVMI and PP. PMID- 30285505 TI - Double stacking cryolipolysis treatment of the abdominal fat with use of a novel contoured applicator. AB - BACKGROUND: Cryolipolysis is a noninvasive method for the selective reduction of subcutaneous fat. The abdomen and flank area are most commonly treated sites and now the treatment efficacy became the important issue. OBJECTIVES: To evaluate the effectiveness and safety of double stacking cryolipolysis treatment with the novel contoured applicator for abdominal fat reduction. MATERIALS AND METHODS: 12 healthy Korean were treated using cryolipolysis contact device. The device was applied on participant's left lower abdomen. Performance was held for 35 minutes and immediately repeated the second performance. The right abdomen was left untreated. Participants were examined with high resolution ultrasound and the depth of subcutaneous fat layer was measured initially and 8 weeks after the sessions. Any adverse events were assessed during the entire study period. RESULTS: The subjective reduction of abdominal fat was noted in most participants. No serious adverse events was reported. Reduction of subcutaneous fat layer depth was confirmed in high resolution ultrasound after 8 weeks of treatment. CONCLUSION: The results of this study indicate that abdominal fat can be reduced effectively by the novel cryolipolysis applicator. With subjective satisfaction of participants our study shows that double stacking treatment appears safe and well tolerated with enhanced treatment outcomes. PMID- 30285506 TI - Comparative efficacy of short-pulsed intense pulsed light and pulsed dye laser to treat rosacea. AB - BACKGROUND: Laser and light-based therapies have often been used successfully to treat rosacea. Recently, short-pulsed intense pulsed light (IPL) that emitted pulse durations down to 0.5 ms was found to be effective for rosacea treatment. OBJECTIVE: This study evaluated the efficacy of short-pulsed IPL in the treatment of rosacea compared with pulsed dye laser (PDL) using same pulse duration and fluence. MATERIALS AND METHODS: Nine patients with rosacea were enrolled in a randomized, split-face trial. Each treatment consisted of four sessions at three week intervals and followed up until three weeks after the last treatment. Efficacy was assessed by erythema, melanin index, physician's subjective evaluation, and patient's satisfaction. RESULTS: The mean change in erythema index was -4.93 +/- 1.59 for the short-pulsed IPL group and -4.27 +/- 1.23 for the PDL group. The mean change in melanin index was -2.52 +/- 2.45 for the short pulsed IPL group and -1.95 +/- 1.41 for the PDL group. There was no significant difference in either melanin or erythema index between short-pulsed IPL and PDL treatments, and there were no noticeable adverse events. CONCLUSIONS: There was no significant difference between PDL and short-pulsed IPL treatment using the same energies and pulse. Both PDL and short-pulsed IPL were satisfactory and safe for rosacea treatment. PMID- 30285507 TI - Greater occipital and supraorbital nerve blockade for the preventive treatment of migraine: a single-blind, randomized, placebo-controlled study. AB - OBJECTIVE: Nerve injections have been used for the acute and preventive treatment of migraine in recent decades. Most of these injections focused on greater occipital nerve (GON) blockade. However, few studies were placebo controlled, and only a few of them investigated GON and supraorbital nerve (SON) blockade together. This study aimed to evaluate the efficacy of GON and SON blockade with local anesthetics for the preventive treatment of migraine without aura. METHODS: Eighty-seven patients diagnosed with migraine without aura were included in the study. Patients were divided randomly. One group was injected with 1% lidocaine, the other group was injected with 0.9% saline. GON and SON injections were done bilaterally. The injections were repeated weekly for 3 weeks. Patients were followed up for 2 months to assess clinical response. RESULTS: Seventy-one patients completed the study. After 2 months, the number of headache days decreased significantly from 12.8 +/- 10.9 to 5.3 +/- 7.4, and VAS decreased from 8.3 +/- 1.0 to 5.5 +/- 1.9 in the blockade group. The number of headache days decreased from 12.4 +/- 10.3 to 7.5 +/- 7.2 and VAS decreased from 8.2 +/- 1.1 to 7.4 +/- 1.3 in the placebo group. Response was seen in 65.1% of the patients in the blockade group (65.4% for episodic migraine, 64.7% for chronic migraine) and 28.6% of the patients in the placebo group. The difference was significant. CONCLUSIONS: The results suggest that GON and SON blockade with lidocaine was more effective than the placebo in the prophylactic treatment of both episodic and chronic migraine. PMID- 30285508 TI - Hypertensive emergencies in diabetic patients from predominantly African American urban communities. AB - AIM: The aim of this study was to identify risk factors for hypertensive emergencies in diabetic patients presenting with severely elevated blood pressure. METHODS: Using electronic medical records, this study identified diabetic patients with hypertensive crisis who presented to the emergency department of Newark Beth Israel Medical Center, Newark, NJ from June 2013 to May 2016. Diabetic patients with hypertensive emergencies were compared with non diabetic patients based on important demographic and clinical characteristics. RESULTS: Patients with diabetes accounted for 52.27% of all hypertensive emergencies during the study period. There were 264 diabetic patients with hypertensive emergencies and 519 diabetic patients with hypertensive urgencies. The majority of patients were African Americans (88.6%). The odds of hypertensive emergencies were strikingly higher in diabetic patients with hyperlipidemia (OR 1.66, 95% CI 1.23-2.24), coronary artery disease (OR 2.95, 95% CI 2.15-4.05), congestive heart failure (OR 6.28, 95% CI 4.49-8.80), renal insufficiency (OR 2.84, 95% CI 2.10-3.86) and low hemoglobin (OR 0.9, 95% CI 0.84-0.97). Acute or worsening heart failure was the most frequent acute target organ injury (49.6%) followed by non-ST elevation myocardial infarction (41.7%). Diabetic and non diabetic patients had similar rates of target organ injuries. CONCLUSION: The development of hypertensive emergencies in patients with diabetes was not because of diabetes per se but because of coexisting highly elevated blood pressure. Tight blood pressure control may decrease the risk of hypertensive emergencies in this patient population. PMID- 30285509 TI - Efficacy and safety of noninvasive focused ultrasound for treatment of subcutaneous adiposity in healthy women. AB - INTRODUCTION: In recent years, a new method focused ultrasound (FUS) has been used in the treatment of localized fat. The objectives of this work were to evaluate the efficacy and safety of the FUS in the treatment of abdominal subcutaneous fat. MATERIALS AND METHODS: Thirty-one healthy women were divided into two groups: G1 (N = 7), 6 sessions, 3 passes, once a week and G2 (N = 23), 10 sessions, 2 passes, twice a week. Outcome measures were reduction of circumference and fat thickness. Safety monitoring included laboratory testing (serum lipids profile and liver function tests) and adverse events were also assessed. Patient satisfaction and tolerance questionnaires were also applied. One patient underwent abdominoplasty and received a single session of FUS 24 h before surgery and a skin sample was collected for histological analysis. RESULTS: The results showed improvement in body contouring and reduction of the thickness of the fat layer observed by ultrasonography in both groups: G1 (P < 0.001) and G2 (P < 0.0001). The histology showed disrupted adipocytes and collapsed membranes 24 h after the FUS treatment. CONCLUSION: FUS represents an effective and safe treatment for reducing localized adipose tissue by adipocytolysis. PMID- 30285510 TI - Relationship between the NF-kappaB1-94ins/del ATTG locus polymorphism and risk of hypertension in the Chinese Han population. AB - OBJECTIVE: The onset of essential hypertension is the result of a combination of genetic factors and the environment. The nuclear factor (NF)-kappaB1-94ins/del ATTG locus polymorphism is associated with the occurrence of various diseases. The purpose of this study was to find out the relationship between the NF-kappaB1 94ins/del ATTG locus polymorphism and the risk of hypertension in the Chinese Han population. METHODS: A total of 585 Chinese Han patients with essential hypertension and 585 Chinese Han healthy volunteers were recruited. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was performed to analyze the genotype of the NF-kappaB1-94ins/del ATTG locus in all the subjects. RESULTS: For the NF-kappaB1-94ins/del ATTG locus, the dominant (adjusted odds ratio [OR] = 1.31, 95% confidence interval [CI] = 1.13-1.54, P < 0.001), recessive (adjusted OR = 1.17, 95% CI = 1.02-1.32, P = 0.03) and additive (adjusted OR = 1.19, 95% CI = 1.03-1.36, P = 0.01) models showed significant increase in the risk of hypertension. The NF-kappaB1-94ins/del ATTG locus II genotype was an independent risk factor for hypertension (OR = 1.15, 95% CI = 0.78-1.69, P = 0.02). The interaction between the NF-kappaB1-94ins/del ATTG locus polymorphism and BMI, alcohol consumption, and diabetes significantly increased the risk of hypertension (OR = 1.71, 95% CI = 1.26-1.86, P < 0.01). CONCLUSION: The NF-kappaB1-94ins/del ATTG polymorphism is an independent risk factor for essential hypertension. The NF-kappaB1-94ins/del ATTG locus, obesity, drinking, and diabetes also interact to yield a higher risk of hypertension. PMID- 30285511 TI - A successful bronchial thermoplasty procedure in a "very severe" asthma patient with rare complications: a case report. AB - INTRODUCTION: Bronchial thermoplasty (BT) is a unique bronchoscopic treatment for severe asthma that utilizes radiofrequency ablation to reduce smooth muscle in the bronchial walls. Current studies mainly focused on uncontrolled severe asthma with a forced expiratory volume in 1 second (FEV1) above 60% and associated complications, no human studies have performed on "very severe" asthma as well as its complications. CASE STUDY: We present a 60-year-old male with more than 15 years history of very severe asthma, who underwent BT. His FEV1 was only 20.4% predicted, which would have excluded him from all prior clinical trials of BT. The first BT procedure occurred without an issue. After the second BT procedure, he experienced severe dyspnea due to an infection with a non-flu respiratory virus. This illness was complicated by the formation of a pulmonary cyst. During recovering from the third procedure, he developed stomach stones. This is mainly related with taking large amounts of hawthorn previously, also cannot exclude the role of thermal energy injury on gastrointestinal nerve function. RESULTS: Despite these unexpected complications, his quality of life greatly improved after BT, yet his lung function did not improve. CONCLUSION: This case is the first to describe BT procedures in patient with this level of lung function compromise, although accompanied with rare complications; our report indicates BT may be an opportunity and choice for the "very severe" asthma patients. PMID- 30285512 TI - The Effect of a Polysaccharide-Based Multinutrient Dietary Supplementation Regimen on Infections and Immune Functioning in Multiple Sclerosis. AB - Multiple sclerosis (MS) is a progressive neurodegenerative disease associated with increased infection rates, chronic inflammation, and premature death. Optimization of nutritional status via dietary supplementation may improve immune function in people suffering from MS and lead to decreased rates of infection. Fifteen individuals with a diagnosis of relapsing-remitting MS for an average of 12.4 years (SD =7.4; R = 2, 25) were enrolled in a one-year open-label clinical trial. Participants consumed a broad-spectrum dietary supplement regimen containing polysaccharides, phytochemicals, antioxidants, vitamins, and minerals three times per day. The occurrence of infections and a panel of cytokines, growth factors, and T- and B-cell subsets were assessed at baseline and 12 months. Seven female and 8 male participants with an average age of 51.3 years (SD =7.2; R = 38, 65) completed the study. At the end of the intervention, participants had fewer total infections (M = 7.9, SD =8.1 at baseline and M = 2.5, SD =4.3 at 12-month follow-up). At 12 months, IL-2, TNF-alpha, EGF, and CD95 + CD34+ significantly increased, while IL-1beta significantly decreased. No major adverse effects were reported; only mild gastrointestinal intolerance was reported in four cases. A decreased occurrence of infection was observed in MS patients treated with 12 months of a polysaccharide-based multinutrient dietary supplement. Significant changes were also noted in several key biomarkers that would be physiologically favorable to the MS population. Thus, the results of this study suggest an immunomodulatory effect of the dietary supplement regimen studied. PMID- 30285513 TI - Successful hyaluronic acid filler injection in a chronic myeloid leukemia patient taking imatinib mesylate. AB - Dermal fillers are highly favored around the globe as minimally invasive or nonsurgical procedures. Imatinib mesylate is the first-line treatment for patients diagnosed with chronic myeloid leukemia. However, some studies describe that imatinib mesylate may increase the tendency of skin fragility which can lead to easy bruising and hyperpigmentation after invasive skin procedures. Yet, to our knowledge, no studies have described any successful dermal filler injection performed on patients who are under imatinib mesylate treatment. Hence, we present a case successfully treated with hyaluronic acid filler injection on a patient under imatinib mesylate treatment. We carefully propose that hyaluronic acid filler can be an effective means of rejuvenation and cosmetic enhancement for those under imatinib mesylate treatment. PMID- 30285514 TI - Choroidal Vascularity Index and Choroidal Thickness in Human Leukocyte Antigen B27-Associated Uveitis. AB - PURPOSE: To assess choroidal thicknesses and choroidal vascularity index (CVI) in HLA-B27-associated uveitis. METHODS: Medical records of 45 treatment-naive unilateral HLA-B27-associated uveitis patients presenting with first episode and with onset time of < 1-week were reviewed. RESULTS: Mean choroidal thickness was 275.98 +/- 71.62 in acute phase and 254.93 +/- 73.48 after resolution (p = .003). Mean CVI was 34.75 +/- 3.08 in acute phase and 33.56 +/- 2.48 after resolution (p < .001). Interestingly, even in fellow eyes, there were relative retinal and choroidal thickening and relative choroidal vascular engorgement in acute phase, but these differences were not significant. Degree of anterior chamber inflammation was correlated with relative choroidal vascular engorgement (p = .001) and choroidal thickening (p = .044). CONCLUSION: Eyes with acute HLA-B27 associated uveitis exhibited choroidal thickening with increased choroidal vascularity that subsequently decreased after uveitis resolution. These were evident even in patients without posterior segment involvement. PMID- 30285515 TI - Peptidyl arginine deiminase inhibition suppresses arthritis via decreased protein citrullination in joints and serum with the downregulation of interlukin-6. AB - OBJECTIVE: To explore the relevance of citrullinated proteins and anti citrullinated protein antibodies (ACPA) via protein arginine deiminase (PAD) inhibition in peptide glucose-6-phosphate isomerase-induced arthritis (pGIA). METHODS: Cl-amidine, a PAD inhibitor, was injected into pGIA. Clinical scores and histopathological findings of ankle joints were assessed. Serum ACPA titers were analyzed using ELISA. Citrullinated protein expression in joints and sera were examined with immunohistochemistry and Western blot analysis, respectively. Serum levels of IL-6, TNFalpha, and IL-1beta were measured with cytometric bead array (CBA). Gene expression levels of IL-6 and TNFalpha in joints, lymph nodes, and spleens were analyzed with quantitative PCR. GPI-specific productions of IFNgamma and IL-17 from T cells in lymph nodes were evaluated. RESULTS: Cl-amidine treatment significantly reduced arthritis severity while ACPA titers tended to be lower, but not significantly different compared to the control. Citrullinated proteins in joints and sera from treated mice were clearly decreased. With Cl amidine treatment, serum IL-6 levels were significantly decreased, and IL-6 and TNFalpha gene expression were significantly reduced in joints. IL-17 production from GPI-specific T cells tended to be lower in Cl-amidine-treated mice, but not significantly different. CONCLUSION: Our results suggested that PAD-mediated citrullinated protein was involved in the pathogenesis of arthritis via IL-6. PMID- 30285516 TI - A benefit and the prospects of IL-6 inhibitors in idiopathic multicentric Castleman's disease. AB - Castleman's disease (CD), a heterogeneous group of lymphoproliferative disorders, is divided into unicentric CD (UCD) and multicentric CD (MCD) based on the number of regions of enlarged lymph nodes with characteristic histopathologic features. The clinical pictures and treatment differ greatly between these UCD and MCD. In MCD, cases of human herpesvirus 8-negative patients with unknown etiology are defined as idiopathic MCD (iMCD). Most cases of UCD are treatable by surgical excision. The prognosis of iMCD varies, and it may be challenging to achieve remission. Glucocorticoids are initiated as the first choice for therapy, but for glucocorticoid-resistant cases, interleukin (IL)-6 inhibition is initiated. However, an IL-6 inhibitor is not effective for all iMCD cases, and refractory cases occur despite these treatments. In this review, we briefly summarize the role of IL-6 in iMCD, and we discuss the efficacy that has been reported for tocilizumab (TCZ), the anti-IL-6 receptor antibody, for patients with iMCD in Japan. Factors predicting the therapeutic response to IL-6 remain to be identified, and the verification of the long-term safety of IL-6 inhibition is needed. PMID- 30285517 TI - Flow cytometry for pediatric platelets. AB - The ability of platelets to carry out their hemostatic function can be impaired in a wide range of inherited and acquired conditions: trauma, surgery, inflammation, pre-term birth, sepsis, hematological malignancies, solid tumors, chemotherapy, autoimmune disorders, and many others. Evaluation of this impairment is vitally important for research and clinical purposes. This problem is particularly pronounced in pediatric patients, where these conditions occur frequently, while blood volume and the choice of blood collection methods could be limited. Here we describe a simple flow cytometry-based screening method of comprehensive whole blood platelet function testing that was validated for a range of pediatric and adult samples (n = 31) in the hematology hospital setting including but not limited to: classic inherited platelet function disorders (Glanzmann's thrombasthenia; Bernard-Soulier, Wiscott-Aldrich, and Hermasky Pudlak syndromes, MYH9-dependent thrombocytopenia), healthy and pre-term newborns, acute and chronic immune thrombocytopenia, chronic lympholeukemia, effects of therapy on platelet function, etc. The method output includes levels of forward and side scatter, levels of major adhesion and aggregation glycoproteins Ib and IIb-IIIa, active integrins' level based on PAC-1 binding, major alpha-granule component P-selectin, dense granule function based on mepacrine uptake and release, and procoagulant activity quantified as a percentage of annexin V-positive platelets. This analysis is performed for both resting and dual-agonist-stimulated platelets. Preanalytical and analytical variables are provided and discussed. Parameter distribution within the healthy donor population for adults (n = 72) and children (n = 17) is analyzed. PMID- 30285518 TI - First-in-Human Phase I, Dose-Escalation and -Expansion Study of Telisotuzumab Vedotin, an Antibody-Drug Conjugate Targeting c-Met, in Patients With Advanced Solid Tumors. AB - PURPOSE: This first-in-human study evaluated telisotuzumab vedotin (Teliso-V), formerly called ABBV-399, an antibody-drug conjugate of the anti-c-Met monoclonal antibody ABT-700 and monomethyl auristatin E. MATERIALS AND METHODS: For dose escalation, three to six patients with advanced solid tumors were enrolled in eight cohorts (0.15 to 3.3 mg/kg). The dose-expansion phase enrolled patients with non-small-cell lung cancer (NSCLC) with c-Met-overexpressing tumors (c-Met positive; immunohistochemistry membrane H-score >= 150). Patients received Teliso V monotherapy intravenously on day 1 once every 3 weeks. Safety, tolerability, pharmacokinetics, and maximum tolerated dose were determined. RESULTS: Forty eight patients were enrolled (median age, 65 years; 35.4% NSCLC; median four prior therapies). One patient each in the 3.0-mg/kg (n = 9) and 3.3-mg/kg (n = 3) cohorts experienced dose-limiting toxicities. Although the maximum tolerated dose was not formally identified, the recommended phase II dose was defined as 2.7 mg/kg on the basis of overall safety and tolerability. The most frequent treatment-emergent adverse events (any grade) were fatigue (42%), nausea (27%), constipation (27%), decreased appetite (23%), vomiting (21%), dyspnea (21%), diarrhea (19%), peripheral edema (19%), and neuropathy (17%). The most frequent Teliso-V-related grade >= 3 adverse events were fatigue, anemia, neutropenia, and hypoalbuminemia (4% each). Teliso-V and total antibody pharmacokinetics were approximately dose proportional, with a mean harmonic half-life of 2 to 4 days each. Prospective screening identified 35 (60%) of 58 patients with c-Met positive NSCLC. Of 16 patients with c-Met-positive NSCLC who were treated with Teliso-V 2.4 to 3.0 mg/kg, three (18.8%; 95% CI, 4.1% to 45.7%) achieved a partial response (median response duration, 4.8 months; median progression-free survival, 5.7 months; 95% CI, 1.2 months to 15.4 months). No other patients experienced a response. CONCLUSION: Teliso-V monotherapy demonstrated favorable safety and tolerability profiles, with encouraging evidence of antitumor activity in patients with c-Met-positive NSCLC. PMID- 30285520 TI - An Urban 9-1-1 System's Experience with Left Ventricular Assist Device Patients. AB - BACKGROUND: Left ventricular assist devices (LVADs) are used with increasing frequency and left in place for longer periods of time. Prior publications have focused on the mechanics of troubleshooting the device itself. We aim to describe the epidemiology of LVAD patient presentations to emergency medical services (EMS), prehospital assessments and interventions, and hospital outcomes. METHODS: This is a retrospective chart review of known LVAD patients that belong to a single academic center's heart failure program who activated the 9-1-1 system and were transported by an urban EMS system to one of the center's 2 emergency departments between January 2012 and December 2015. Identifying demographics were used to query the electronic medical record of the responding city fire agency and contracted transporting ambulance service. Two reviewers abstracted prehospital chief complaint, vital signs, assessments, and interventions. Emergency department and hospital outcomes were retrieved separately. RESULTS: From January 2012 to December 2015, 15 LVAD patients were transported 16 times. The most common prehospital chief complaint was weakness (7/16), followed by chest pain (3/16). Of the 7 patients presenting with weakness, one was diagnosed with a stroke in the emergency department. Another patient was diagnosed with subarachnoid hemorrhage and expired during hospital admission. This was the only death in the cohort. The most common hospital diagnosis was GI bleed (3/16). The overall admission rate was 87.5% (14/16). CONCLUSIONS: EMS interactions with LVAD patients are infrequent but have high rates of admission and incidence of life threatening diagnoses. The most common prehospital presenting symptoms were weakness and chest pain, and most prehospital interactions did not require LVAD specific interventions. In addition to acquiring technical knowledge regarding LVADs, EMS providers should be aware of non-device-related complications including intracranial and GI bleeding and take this into account during their assessment. PMID- 30285519 TI - Real-Time Fatigue Mitigation with Air-Medical Personnel: The SleepTrackTXT2 Randomized Trial. AB - OBJECTIVE: The aims of this study were: 1) to determine the short-term impact of the SleepTrackTXT2 intervention on air-medical clinician fatigue during work shifts and 2) determine the longer-term impact on sleep quality over 120 days. METHODS: We used a multi-site randomized controlled trial study design with a targeted enrollment of 100 (ClinicalTrials.gov NCT02783027). The intervention was behavioral (non-pharmacological) and participation was scheduled for 120 days. Participation was voluntary. All consented participants answered baseline as well as follow-up surveys. All participants answered text message queries, which assessed self-rated fatigue, sleepiness, concentration, recovery, and hours of sleep. Intervention participants received additional text messages with recommendations for behaviors that can mitigate fatigue. Intervention participants received weekly text messages that promoted sleep. Our analysis was guided by the intent-to-treat principle. For the long-term outcome of interest (sleep quality at 120 days), we used a two-sample t-test on the change in sleep quality to determine the intervention effect. RESULTS: Eighty-three individuals were randomized and 2,828 shifts documented (median shifts per participant =37, IQR 23-49). Seventy-one percent of individuals randomized (n = 59) participated up to the 120-day study period and 52% (n = 43) completed the follow-up survey. Of the 69,530 text messages distributed, participants responded to 61,571 (88.6%). Mean sleep quality at 120 days did not differ from baseline for intervention (p > 0.05) or control group participants (p > 0.05), and did not differ between groups (p > 0.05). There was no change from baseline to 120 days in the proportion with poor sleep quality in either group. Intra-shift fatigue increased (worsened) over the course of 12-hour shifts for participants in both study arms. Fatigue at the end of 12-hour shifts was higher among control group participants than participants in the intervention group (p < 0.05). Pre-shift hours of sleep were often less than 7 hours and did not differ between the groups over time. CONCLUSIONS: The SleepTrackTXT2 behavioral intervention showed a positive short-term impact on self-rated fatigue during 12-hour shifts, but did not impact longer duration shifts or have a longer-term impact on sleep quality among air-medical EMS clinicians. PMID- 30285521 TI - An exploratory study on the role of vitamin D supplementation in improving pain and disease activity in rheumatoid arthritis. PMID- 30285522 TI - CFH Y402H polymorphism in Italian patients with age-related macular degeneration, retinitis pigmentosa, and Stargardt disease. AB - BACKGROUND: The complement system has been implicated in the pathogenesis of age related macular degeneration (AMD) and the CFH Y402H polymorphism has been suggested as a major risk factor for AMD. Recent evidences supported the role of inflammation in the pathogenesis of some retinal dystrophies. Aim of this study was to evaluate the prevalence of CFHY402H polymorphism in a group of Italian patients affected by atrophic AMD, Stargardt disease (STGD), or retinitis pigmentosa(RP). MATERIALS AND METHODS: Our case-control association study included 116 patients with atrophic AMD, 77 with RP, 86 with STGD, and 100 healthy controls. All the patients were evaluated by a standard ophthalmologic examination and OCT. ERG was performed on STGD and RP patients. All the subjects underwent a blood drawing for genetic testing and the CFHY402H polymorphism was genotyped with the TaqMan real-time polymerase chain reaction single nucleotide polymorphism assay. RESULTS: The prevalence of the risk genotype C/C was higher in the AMD group than in controls (p < 0.001). The risk allele C was more frequent in the AMD group than in controls (p < 0.001). The prevalence of the risk genotype was higher in the RP patients than in controls (p < 0.001) and similarly the risk allele C was more frequent in the RP group (p = 0.008). The CFHY402H genotype distribution was not different between patients with STGD and the controls, for the biallelic (p = 0.531) and for the monoallelic (p = 0.318) evaluation. CONCLUSIONS: In our series of Italian patients, the CFHY402H genotype is associated with atrophic AMD and RP, but not with STGD. This result may support the hypothesis of a complement system dysregulation in the pathogenesis of AMD and RP. PMID- 30285523 TI - Proximal External Aortic Compression for Life-Threatening Abdominal-Pelvic and Junctional Hemorrhage: An Ultrasonographic Study in Adult Volunteers. AB - INTRODUCTION: Following life-threatening junctional trauma, the goal is to limit blood loss while expediting transfer to operative rescue. Unfortunately, life threatening abdominal-pelvic or junctional hemorrhage is often not amenable to direct compression and few temporizing strategies are available beyond hemostatic dressings, hypotensive resuscitation, and balanced transfusion. OBJECTIVES: In this study, we evaluated proximal external aortic compression to arrest blood flow in healthy adult men. METHODS: This was a simulation trial of proximal external aortic compression, for life-threatening abdominal-pelvic and junctional hemorrhage, in a convenience sample of healthy adult male volunteers. The primary end points were cessation of femoral blood flow as assessed by pulse wave Doppler ultrasound at the right femoral artery, caudal to the inguinal ligament. Secondary end points were discomfort and negative sequelae. RESULTS: Aortic blood flow was arrested in 12 volunteers. Median time to blood flow cessation was 12.5 seconds. Median reported discomfort was 5 out of 10. No complications or negative sequelae were reported. CONCLUSION: This trial suggests that it may be reasonable to attempt temporization of major abdominal-pelvic and junctional hemorrhage using bimanual proximal external aortic compression. In the absence of immediate alternatives for this dangerous and vexing injury pattern, there appear to be few downsides to prehospital proximal external aortic compression while concomitantly expediting definite care. PMID- 30285524 TI - Characteristics and management of congenital anophthalmos and microphthalmos at a tertiary eye hospital. AB - PURPOSE: The purpose of the study is to evaluate demographic data and outcomes of the management of congenital anophthalmia/microphthalmia. METHODS: This retrospective, descriptive, cross-sectional study evaluated patients with congenital anophthalmia/microphthalmia managed from 2004 to 2014 at a tertiary hospital in Saudi Arabia. Data were collected on patient age, gender, cause, orbital status, laterality, systemic comorbidities, ocular evaluation, and management (type of surgery, type of orbital implant, and complications). The main outcome measure was the ability to hold the prosthesis. RESULTS: The study sample was composed of 513 eyes/sockets of 365 patients. Two-hundred and seventeen (59.4%) patients were unilateral cases. Forty-one (8%) sockets were due to congenital anophthalmia and 471 (92%) were due to microphthalmia. There were 73.2% isolated cases and 28.5% with systemic involvement. Systemic involvement was more common in bilateral cases. The most commonly associated conditions were central nervous disorders. One-hundred and nineteen (46.7%) cases had parental consanguinity. Two hundred and eighteen eyes/sockets (163 patients) underwent surgery including conjunctival flap (38; 17.4%), evisceration (38; 17.4%), enucleation (16; 7.3%), or procedures to improve the anophthalmic socket volume (45; 20.6%). Volume enhancing procedures included polymethylmethacrylate orbital implants (26; 57.8%), expanders (11; 24.4%), integrated hydroxyapatite or polyethylene implants (2; 4.4%), and dermis-fat graft (6; 13.3%). In most cases, clinical or surgical management resulted in a successful outcome. CONCLUSION: Anophthalmia/Microphthalmia was detected in 36.5 patients/year. The majority had isolated microphthalmia. Good outcomes were achieved with clinical or surgical management in the majority of cases.

PMID- 30285525 TI - Focal and segmental glomerulosclerosis in murine models: a histological and ultrastructural characterization with immunohistochemistry correlation of glomerular CD44 and WT1 expression. AB - AIM: Focal segmental glomerulosclerosis (FSGS) is a common progressive chronic renal disease. Podocyte injury and loss are the postulated pivotal events that trigger FSGS. In this study, the authors aim to examine the evolution of FSGS in murine models histologically, ultrastructurally and immunohistochemically with special emphasis on podocytes and parietal epithelial cells (PECs). MATERIAL AND METHODS: FSGS resembling primary FSGS in humans was initiated in Wistar rats using intravenous Adriamycin injections. Blood and urine analysis were performed at 0, 8, and 12 weeks. Both the control kidneys and the test kidneys were harvested at 8 and 12 weeks, examined histologically and ultrastructurally and the findings correlated with the glomerular expression of immunostains specific for podocytes (WT-1) and for activated PECs (CD44). RESULTS: FSGS developed in both 8 and 12 weeks test groups showing progressive proteinuria, podocytopathy and segmental glomerular scarring. There was a decrease in the glomerular expression of WT-1 with a concurrent increase in the glomerular expression of CD44, indicating podocyte loss with synchronous increase in activated PECs. The evolving FSGS correlated negatively with podocytes and positively with activated PECs. CONCLUSION: Our study shows that with podocyte injury there is podocyte effacement and loss, proteinuria, glomerular segmental adhesion and scarring, all culminating in FSGS. In addition, there is activation, hyperplasia and hypertrophy of PECs. This demonstrates that both podocyte loss and PEC activation promote FSGS. Our findings are consistent with recent investigations. More studies are required to further understand the role of these cells in the evolution of FSGS and subsequently introduce new targeted treatment modalities. PMID- 30285527 TI - Early Menarche and Risk of Metabolic Syndrome: A Systematic Review and Meta Analysis. AB - BACKGROUND: The association between age at menarche and metabolic syndrome was inconsistent across studies and remains unclear. We conducted a systematic review and meta-analysis of observational studies to assess the association between age at menarche and risk of metabolic syndrome, comprehensively. MATERIALS AND METHODS: The PubMed and ISI Web of Science databases were searched for all articles published through May 2017, and the reference lists of the retrieved articles were reviewed. Pooled relative risks (RRs) with 95% confidence intervals (CIs) were calculated using a random-effects model through combining the study specific estimates adjusting for potential confounders. RESULTS: Sixteen observational studies were eligible for the meta-analysis of age at menarche and metabolic syndrome, which included 13,657 cases among 51,453 subjects. The pooled RR of metabolic syndrome for the youngest versus the oldest categories of age at menarche was 1.62 (95% CI: 1.40-1.88) (p for heterogeneity = 0.01, I2 = 57.3%). The analysis of 1-year decrease in age at menarche conferred a pooled RR of 1.08 (95% CI: 1.01-1.15), suggesting an 8% increase in risk of metabolic syndrome. The association between age at menarche and the risk of metabolic syndrome did not vary by study design, geographical region, number of subjects, and adjustment for confounders. CONCLUSIONS: Our findings from the current meta-analysis suggest that earlier menarcheal age is associated with higher risk of metabolic syndrome. Age at menarche may help identify women with higher risk of metabolic syndrome. Further well-designed cohort studies are warranted to provide definitive evidence. PMID- 30285528 TI - Registered blindness in Kuwait - 15 years of dynamic changes. AB - PURPOSE: Incidence rate of registered blindness and low vision (IR) among the Kuwaitis from 2005 to 2014 and longitudinal changes since 2000. METHODS: Data of newly certified Kuwaitis with best-corrected visual acuity 0.1 or less or visual field constriction to 20 degrees or less in their better eye, aggregated in intervals from 2005 to 2009 and 2010 to 2014 and presented as IR per 100 000 person years of observation by age, gender, severity and leading cause. RESULTS: Delayed certification resulted in rise of IR from 2005. IR of males declined since 2010, whereas among the females it continued rising at a slower rate. After 2010 IR of patients from 40 to 59 years expanded significantly and declined in the group over 60 years. Retinitis pigmentosa was the leading cause driven by high prevalence of consanguineous marriages; the large difference between the males and females is due mainly to cultural factors. Diabetic complications escalated from 2005 affecting patients over 40 years. Glaucoma became the leading cause in the age over 60 years after 2005 and while the male patients decreased after 2010 by 18%, disabled females grew by further 35%. CONCLUSIONS: Demographic, social and behavioral factors had impact on the structure and time trends of registered blindness among the Kuwaitis. High prevalence of diabetes and aging of the population resulted in rise of certification from diabetic complications and glaucoma in the last 10 years. PMID- 30285530 TI - Management of Early Head and Neck Cancer in Elderly Patients. AB - Head and neck squamous cell carcinoma (HNSCC) frequently affects elderly patients. Given the frailty and comorbid conditions of this population as well as the potential toxicities associated with treatment, there is a risk of undertreatment in older patients. However, there is growing evidence that benefit with standard treatment is similar in the elderly and in younger patients. Few prospective trials specifically target the elderly, which forces clinicians to rely on subgroup analyses and retrospective data. Therefore, adequate pretreatment assessments are vital to anticipate factors that may contribute to morbidity during therapy. In addition, supportive care during treatment is essential. For patients of all ages who present with early or localized disease, curative treatment should be offered whenever possible. With more precise surgical and radiologic techniques, the ability to provide curative treatment while minimizing long-term toxicity has greatly improved. Not only our techniques but also our understanding of the disease have improved. Human papillomavirus (HPV)-related HNSCC has changed the treatment paradigm of advanced-stage disease because of the inherently better prognosis compared with tobacco- and alcohol related HNSCC. How this will affect early-stage disease remains to be seen, but de-escalated therapy may prove a suitable strategy in eligible elderly patients. With improved therapies and understanding of the disease, additional prospective trials must be carried out in the elderly population. PMID- 30285529 TI - What Can Be Done to Improve Research Biopsy Quality in Oncology Clinical Trials? AB - PURPOSE:: Research biopsy specimens collected in clinical trials often present requirements beyond those of tumor biopsy specimens collected for diagnostic purposes. Research biopsies underpin hypothesis-driven drug development, pharmacodynamic assessment of molecularly targeted anticancer agents, and, increasingly, genomic assessment for precision medicine; insufficient biopsy specimen quality or quantity therefore compromises the scientific value of a study and the resources devoted to it, as well as each patient's contribution to and potential benefit from a clinical trial. METHODS:: To improve research biopsy specimen quality, we consulted with other translational oncology teams and reviewed current best practices. RESULTS:: Among the recommendations were improving communication between oncologists and interventional radiologists, providing feedback on specimen sufficiency, increasing academic recognition and financial support for the time investment required by radiologists to collect and preserve research biopsy specimens, and improving real-time assessment of tissue quality. CONCLUSION:: Implementing these recommendations at the National Cancer Institute's Developmental Therapeutics Clinic has demonstrably improved the quality of biopsy specimens collected; more widespread dissemination of these recommendations beyond large clinical cancer centers is possible and will be of value to the community in improving clinical research and, ultimately, patient care. PMID- 30285531 TI - Rheumatic diseases associated with immune checkpoint inhibitors in cancer immunotherapy. AB - Immune checkpoint inhibitors (ICIs) have drastically altered cancer treatment paradigms, with increasing numbers of novel ICIs being currently evaluated in numerous clinical trials for various cancers. ICIs release "brakes" against tumor immunity to control cancer growth via T cell-dependent anti-tumor activity. Meanwhile, side effects associated with ICIs are directly related to their mechanism of action, as nonspecific immune activation targeting non-tumor organs results in undesirable off-target inflammation and autoimmunity. Accumulating data reveal that immune-related adverse events (irAEs) of ICIs in cancer patients can resemble various rheumatic diseases. Moreover, while patients with preexisting rheumatic diseases can theoretically experience irAEs and disease flares, observational studies have shown that ICIs can be used successfully in these patients. As ICIs continue to provide long-lasting disease control in cancer patients and their usage correspondingly increases, the rheumatologist will be managing new ICI-associated clinical entities mimicking common autoimmune diseases and will need to be prepared to rapidly diagnose and treat these irAEs. Early recognition and treatment of these rheumatic adverse events will allow for improved outcomes and quality of life for cancer patients faced with previously rapidly fatal disease. PMID- 30285532 TI - A high incidence of extensor pollicis brevis insertion into the distal phalanx in rheumatoid arthritis patients who required the surgical reconstruction for thumb boutonniere deformity. AB - OBJECTIVES: The aim of the current study was to investigate the pattern of extensor pollicis brevis (EPB) insertion macroscopically and histologically using cadaveric thumbs, and to compare the incidence of different insertions with that of thumb boutonniere deformity in rheumatoid arthritis (RA) patients who required surgical reconstruction. METHODS: We examined 103 thumbs of 58 adult cadavers with no evidence of RA, and reviewed the surgical records of 28 thumbs of 23 RA patients who underwent surgical reconstruction for thumb boutonniere deformity. The incidence of different insertion patterns of the cadaveric thumbs and the RA thumbs were compared using the Fisher's exact test. RESULTS: Macroscopic and histologic examination revealed that the insertion patterns of EPB could be divided into three groups: insertion into the base of the proximal phalanx (Type P1), integration of EPB into the dorsal fibrocartilage of the MCP joint (Type P2), and insertion into the distal phalanx (Type D). The incidence of Type D was significantly higher in RA patients with thumb boutonniere deformity (64%) than that in the non-RA cadavers (29%; P < 0.05). CONCLUSIONS: EPB is inserted into the distal phalanx more frequently in RA patients who require surgery for thumb boutonniere deformity than non-RA cadavers, suggesting an additional possible mechanism of this deformity. PMID- 30285533 TI - Safety and effectiveness of high-dose methotrexate (over 8 mg/week) in 2838 Japanese patients with rheumatoid arthritis: A postmarketing surveillance report. AB - OBJECTIVES: To confirm the safety and effectiveness of high-dose (>8 mg/week) methotrexate (MTX) for the treatment of rheumatoid arthritis in Japan. METHODS: A postmarketing surveillance program enrolled Japanese patients with rheumatoid arthritis starting on high-dose MTX followed up for 24 or 52 weeks. Analyses for safety, risk factors affecting safety, and effectiveness were conducted. RESULTS: The safety/effectiveness analysis sets included 2838/2779 and 335/326 patients in the 24-week and 52-week follow-up groups, respectively. Incidence of adverse drug reactions (ADRs) and serious ADRs was 21.42% and 1.66% in the 24-week and 35.52% and 2.69% in the 52-week groups, respectively. The Disease Activity Score in 28 Joints (DAS28) was significantly decreased as early as four weeks from the start of high-dose MTX; after 24-week (4.09-3.21) and 52-week treatment (3.91-2.80; both p<.001). In a majority of patients at baseline who had high-to-moderate disease activity, the remission rate (defined as DAS < 2.6) increased three-fold from 10.6% (baseline) to 33.0% (24-week) compared to patients with low disease activity whose remission rate increased two-fold from 24.0% (baseline) to 53.6% (24-week). CONCLUSION: High-dose MTX was well tolerated in Japanese patients, resulted in improved disease control, and can be considered a step forward in achieving treat-to-target goals. PMID- 30285534 TI - Should End-of-Life Preferences Be Discussed Routinely before High-Risk Surgery? AB - Encapsulating peritoneal sclerosis (EPS) is a rare but devastating complication of peritoneal dialysis. It is characterized by peritoneal neovascularization, fibrosis, and calcification ultimately leading to intestinal obstruction and eventual failure. Surgery for EPS has a mortality approaching 50% and most patients require some form of postoperative life-sustaining therapy (LST) during their admission. A 43-year-old gentleman with progressive EPS and significant comorbidities was assessed for enterolysis after a failed first attempt at another center. Because of his comorbidities, postoperative mortality was quoted above 50%. The patient favored surgery to improve his survival and quality of life, but was reluctant to receive prolonged LST in the event of failure of surgical therapy. The surgical team, in conjunction with a palliative care physician, therefore held extensive discussions with the patient and his partner regarding LST and its limitations. Clinical parameters to trigger a transition to palliative care were identified and agreed. Limitations on LST that are directly expressed by patients can represent a contraindication to surgery for many surgeons. Surgical Buy-In is a concept described as a perceived contract, or covenant, between the patient and clinician regarding implied consent for postoperative LST. Currently, preoperative discussions regarding limitations of LST are infrequent, and there can be reticence among patients and surgeons to have these conversations, leading to dissatisfaction on behalf of the patient and their family. After the Montgomery legal ruling, the provision and perception of informed consent are particularly pertinent. The palliative care physician is uniquely placed to contribute to such discussions as part of the surgical multidisciplinary team. PMID- 30285535 TI - Evaluation of pressurised carbon dioxide pre-treatment aimed at improving the sanitisation and anaerobic digestibility of co-settled sewage sludge. AB - This work reports on the use of pressurized CO2 pretreatment to improve methane yield and pathogen indicator organism die-off in co-settled sewage sludge (SS). Four semi-continuous mesophilic anaerobic digesters were fed on co-settled SS to establish a baseline for performance and stability. One pair of digesters was then fed with co-settled SS pretreated by P CO2 at 2800 kPa for 23 h. The trial continued for 70 days during which specific biogas and methane production, volatile solids destruction and loss of viability of Escherichia coli was monitored in test and control digesters. The pretreatment had no positive influence on any of these parameters, which was further confirmed using batch biochemical methane potential tests and direct measurement of die-off of E. coli and Salmonella enterica in samples of different sizes treated in pressure vessels of different sizes and in matrices of nutrient medium and co-settled SS. Pressurised CO2 pretreatment was effective at killing fecal indicator bacteria in nutrient medium but ineffectual in SS, strongly suggesting that the nature of suspending matrix was a principle determining factor. Paper concludes that pressurized CO2 pretreatment is not a satisfactory approach to improve either biogas production or pathogen destruction in anaerobic digestion. PMID- 30285536 TI - The Binary Bias: A Systematic Distortion in the Integration of Information. AB - One of the mind's most fundamental tasks is interpreting incoming data and weighing the value of new evidence. Across a wide variety of contexts, we show that when summarizing evidence, people exhibit a binary bias: a tendency to impose categorical distinctions on continuous data. Evidence is compressed into discrete bins, and the difference between categories forms the summary judgment. The binary bias distorts belief formation-such that when people aggregate conflicting scientific reports, they attend to valence and inaccurately weight the extremity of the evidence. The same effect occurs when people interpret popular forms of data visualization, and it cannot be explained by other statistical features of the stimuli. This effect is not confined to explicit statistical estimates; it also influences how people use data to make health, financial, and public-policy decisions. These studies ( N = 1,851) support a new framework for understanding information integration across a wide variety of contexts. PMID- 30285537 TI - The impact of Measles-Rubella vaccination on the morbidity and mortality from Congenital Rubella Syndrome in 92 countries. AB - Since 2011, GAVI, The Vaccine Alliance, has funded eligible countries to introduce rubella-containing vaccination (RCV) into their national schedule. Two key indicators used to monitor the impact - the future deaths and DALYs (Disability Adjusted Life Years) averted through vaccination conducted in specific periods - are poorly understood for rubella and Congenital Rubella Syndrome (CRS). We calculate these indicators using an age-structured dynamic transmission model for rubella, with historical vaccination coverage projections during 2001-30 in 92 low and middle-income countries considered most likely to require global support to achieve the Global Vaccine Action Plan's objectives. 131,000 CRS deaths and 12.5 million DALYs may be prevented with immunization campaigns at best-estimate coverage during 2001-30, relative to those without additional support. The impact depended on the time period considered and the method for attributing deaths averted to vaccination in specific periods. The analyses support ongoing activities to reduce CRS-related morbidity and mortality. PMID- 30285538 TI - Effects of Quercetin on Lipid and Protein Damage in the Liver of Streptozotocin Induced Experimental Diabetic Rats. AB - Quercetin (QR) is part of a subclass of flavonoids called flavonols. We aimed to investigate the effect of QR on malondialdehyde (MDA), advanced oxidation protein products (AOPPs), and glutathione peroxidase (GSH-Px) activity in the liver of diabetic rats. We compared four groups of male adult Wistar albino rats: a control group, an untreated diabetic group, diabetic groups treated with QR, and QR group. Diabetes was induced by a single injection of streptozotocin (STZ) (50 mg/kg). Animals were kept in standard condition. On the 31st day of the study, the liver tissue was removed for biochemical parameters and histopathological evaluations. In an untreated diabetic group, liver MDA and AOPP levels were significantly higher than all groups. QR treatment significantly decreased the increased MDA, AOPP levels, and increased the decreased GSH-Px enzyme activity in liver tissues. The QR-treated rats in the diabetic group showed an improved histological appearance. Lesser vesicular vacuolization and fibrotic areas were observed in the QR-treated diabetic group than in the diabetic group. The STZ induced liver injury is associated with oxidative stress, and coadministration of QR may reduce this damage effectively in a rat model. Our results are also supported by morphological improvement in liver tissue. Therefore, we think QR may be effective in treating hyperglycemia and oxidative damage in diabetes.

Antisense gapmer, steric block, spliceswitching ONs, and short interfering RNA drugs have been successfully developed. Moreover, antagomirs (antimicroRNAs), microRNA mimics, aptamers, DNAdecoys, DNAzymes, synthetic guide strands for CRISPR/Cas, and innate immunity-stimulating ONs are all in clinical trials. DNAtargeting, triplex-forming ONs and strand-invading ONs have made their mark on drug development research, but not yet as medicines. Both design and synthetic nucleic acid chemistry are crucial for achieving biologically active ONs. The dominating modifications are phosphorothioate linkages, base methylation, and numerous 2'-substitutions in the furanose ring, such as 2'-fluoro, O-methyl, or methoxyethyl. Locked nucleic acid and constrained ethyl, a related variant, are bridged forms where the 2'-oxygen connects to the 4'-carbon in the sugar. Phosphorodiamidate morpholino oligomers, carrying a modified heterocyclic backbone ring, have also been commercialized. Delivery remains a major obstacle, but systemic administration and intrathecal infusion are used for treatment of the liver and brain, respectively. Expected final online publication date for the Annual Review of Pharmacology and Toxicology Volume 59 is January 6, 2019. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates. PMID- 30285539 TI - Ploidy Has Minimal Effect on Hypoxia Tolerance at High Temperature in Rainbow Trout (Oncorhynchus mykiss). AB - Polyploidy is an important driver of evolutionary change (generally via tetraploidy) and also serves a practical role in aquaculture and fisheries management (via triploidy). Fundamental changes in cell size and number that accompany polyploidy are predicted to affect cellular and whole-animal physiology due to constraints placed on surface-mediated processes at the cellular level, potentially altering environmental tolerances and optima. The aim of this study was to determine whether the documented reduction in thermal tolerance of aquatic polyploids is a result of their being less hypoxia tolerant. This was assessed by holding diploid and triploid rainbow trout for 1 h above their thermal optima in separate trials at eight temperatures between 20 degrees and 27 degrees C and then rapidly reducing the oxygen tension (Po2) of the water and determining the nonlethal Po2 at which fish lost equilibrium. As expected, there was a highly significant ([Formula: see text]) effect of temperature on Po2 at loss of equilibrium. Although there was also a significant ([Formula: see text]) effect of ploidy on Po2 at loss of equilibrium, with triploid values higher than diploid, post hoc analyses showed no significant effect of ploidy at any specific temperature. Oxygen availability alone therefore does not appear to play a major role in determining the thermal tolerance of polyploids. PMID- 30285541 TI - Mind the Depth: Visual Perception of Shapes Is Better in Peripersonal Space. AB - Closer objects are invariably perceived as bigger than farther ones and are therefore easier to detect and discriminate. This is so deeply grounded in our daily experience that no question has been raised as to whether the advantage for near objects depends on other features (e.g., depth itself). In a series of five experiments ( N = 114), we exploited immersive virtual environments and visual illusions (i.e., Ponzo) to probe humans' perceptual abilities in depth and, specifically, in the space closely surrounding our body, termed peripersonal space. We reversed the natural distance scaling of size in favor of the farther object, which thus appeared bigger, to demonstrate a persistent shape discrimination advantage for close objects. Psychophysical modeling further suggested a sigmoidal trend for this benefit, mirroring that found for multisensory estimates of peripersonal space. We argue that depth is a fundamental, yet overlooked, dimension of human perception and that future studies in vision and perception should be depth aware. PMID- 30285542 TI - Amphiphilic block copolymer NPs obtained by coupling ricinoleic acid/sebacic acids and mPEG: Synthesis, characterization, and controlled release of paclitaxel. AB - Currently, nanoparticles (NPs) made of amphiphilic block copolymer are still an essential part of drug delivery system. Here, we report a novel amphiphilic block copolymer and paclitaxel (PTX)-loaded copolymer NPs for the controlled delivery of PTX. The block copolymer was synthesized via melt polycondensation method of methoxy poly(ethylene glycol) (mPEG), sebacic acid (SA) and ricinoleic acid (RA). A series of characterization approaches such as Fourier Transform Infrared Spectroscopy (FTIR), 1Hydrogen-Nuclear Magnetic Resonance (1H-NMR), Differential Scanning Calorimetry (DSC), X-Ray Diffraction (XRD) and Gel Permeation Chromatography (GPC) applied have shown that the amphiphilic block copolymer was prepared as designed. NPs prepared by nanoprecipitation method consist of mPEG segments as the hydrophilic shell and RA-SA segments as the hydrophobic core, hydrophobic PTX was encapsulated as model drug. Subsequently, Transmission Electron Microscopy (TEM) analysis indicated that the spherical NPs have effective mean diameters ranging from 100 to 400 nm. Dynamic Light Scattering (DLS) analysis also revealed the controllable NPs diameter by modulating the mass ratio of RA to SA and drug loading amount (DLA). Besides, biphasic profile with zero order drug release was observed in general in vitro release behaviors of PTX from NPs. Further investigation confirmed that the release behaviors depend on the crystallinity of hydrophobic RA-SA segments. Results above suggest that NPs with amphiphlic block copolymer mPEG-b-P(RA-SA)-b-mPEG have a remarkable potential as a carrier for hydrophobic drug delivery in cancer therapy. PMID- 30285545 TI - Antidiabetic Activity of Triticum aestivum Seed-Based Diet on Alloxan-Induced Diabetic Rats. AB - The antidiabetic activity of Triticum aestivum seed-based diet on alloxan-induced diabetic rats was investigated. Forty-eight male and female albino rats of four groups were used for this study. Rats were sacrificed on day 28 and organs of interest were excised. Triticum aestivum seed-based diet significantly (p < .05) reversed the levels of fasting blood glucose, albumin, globulin, bilirubin, urea, creatinine, Na+, and K+. In addition, diabetic rats fed Triticum aestivum seed based diet had significantly (p < .05) increased insulin and glycogen concentrations, activities of hexokinase, catalase, superoxide dismutase, and glutathione peroxidase and the levels of hematological parameters studied. Diabetic rats fed on Triticum aestivum seed had significantly (p < .05) reduced activities of glucose-6-phosphatase and fructose 1,6-diphosphatase and concentration of MDA and reversed activities of AST and GGT; ALP and regeneration of liver, kidney, and pancreas tissues compared favorably with the control group from histological examination results. Consumption of this diet may be useful for diabetes mellitus patients in ameliorating diabetes mellitus and its complications. PMID- 30285546 TI - Molecular self-assembly of copolymer from renewable phenols: new class of antimicrobial ointment base. AB - Ointments are highly viscous forms intended for external applications either medicated or non-medicated means. Formulation of ointment depends upon the base ingredients to measure the viscosity difference. Several limitations of ointment bases has been encountered timely as agglomeration, oil phase ingredients can form lumps, poor dispersion, poor drug delivery efficiency, make stained, immiscible, and difficult to wash off. Therefore, it is necessary to make a new type of ointment bases that can overcome those limitations. This review summarizes a new type of ointment base preparation from the copolymer of renewable phenolic derivatives. The nanohydrogel preparation from these copolymers are especially effortless and highly efficient in drug delivery, exhibited versatile biological activities such as antioxidant, anti-inflammatory and wound healing in addition to antimicrobial property. Molecular self-assembly mechanisms have been addressed for nanogel formulation. The strategy makes a significant value in health-care application and be supposed to come marketed soon. PMID- 30285547 TI - How age-of-death and mode-of-death impact perceptions of the deceased. AB - The goal of the current study was to explore how age-of-death (AOD) and mode-of death MOD simultaneously influence ratings of sympathy, empathy, and tragedy toward the deceased in order to assess social value. Three hundred and fifty eight participants, mainly undergraduates, responded to a series of vignettes that described a MOD (suicide, accident, or stroke) counterbalanced with three AODs (younger, middle-aged, and older). Overall, ratings of sympathy, empathy, and tragedy declined as AOD increased; however, the effect of AOD was not consistent across all MODs. The pattern of results suggests that death norms and perceived control of death impact the perception of the deceased. PMID- 30285548 TI - Link Between Facial Identity and Expression Abilities Suggestive of Origins of Face Impairments in Autism: Support for the Social-Motivation Hypothesis. AB - Individuals with autism spectrum disorder (ASD) often have difficulties with processing identity and expression in faces. This is at odds with influential models of face processing that propose separate neural pathways for the identity and expression domains. The social-motivation hypothesis of ASD posits a lack of visual experience with faces as the root cause of face impairments in autism. A direct prediction is that identity and expression abilities should be related in ASD, reflecting the common origin of face impairment in this population. We tested adults with and without ASD ( ns = 34) in identity and expression tasks. Our results showed that performance in the two domains was significantly correlated in the ASD group but not in the comparison group. These results suggest that the most likely origin for face impairments in ASD stems from the input stage impacting development of identity and expression domains alike, consistent with the social-motivation hypothesis. PMID- 30285549 TI - Kinetics and isotherm modeling of azoxystrobin and imidacloprid retention in biomixtures. AB - The paper reports the kinetics and adsorption isotherm modeling for imidacloprid (IMIDA) and azoxystrobin (AZOXY) in rice straw (RS)/corn cob (CC) and peat (P)/compost (C) based biomixtures. The pseudo-first-order (PFO), pseudo-second order (PSO), Elovich and intraparticle diffusion models were used to describe the kinetics. The adsorption data were subjected to the Langmuir and the Freundlich isotherms. Results (r2Adj values) suggested that the modified Elovich model was the best suited to explain the kinetics of IMIDA sorption while different models explained AZOXY sorption kinetics in different biomixtures (PFO in RS + C and RS + P; PSO in CC + P and Elovich in CC + C). Biomixtures varied in their capacity to adsorb both pesticides and the adsorption coefficient (Kd) values were 116.8 369.24 (AZOXY) and 24.2-293.4 (IMIDA). The Freundlich isotherm better explained the sorption of both pesticides. Comparison analysis of linear and nonlinear method for estimating the Freundlich adsorption constants was made. In general, r2Adj values were higher for the nonlinear fit (AZOXY = 0.938-0.982; IMIDA = 0.91 0.970) than the linear fit (AZOXY = 0.886-0.993; IMIDA = 0.870-0.974) suggesting that the nonlinear Freundlich equation better explained the sorption. The rice straw-based biomixtures performed better in adsorbing both the pesticides and can be used in bio-purification systems. PMID- 30285550 TI - Comparison of the Photodegradation of Imazethapyr in Aqueous Solution, on Epicuticular Waxes, and on Intact Corn (Zea Mays) and Soybean (Glycine Max) Leaves. AB - A direct, controlled comparison of the photodegradation of imazethapyr has been made between imazethapyr in aqueous solutions, imazethapyr on the surface of epicuticular waxes of corn and soybean plants, and imazethapyr on the surface of intact corn and soybean plant leaves. In some experiments, the imazethapyr solutions were allowed to evaporate partially or fully after application to better model environmental conditions. The photodegradation of imazethapyr was fastest in aqueous solutions (k = 0.16 +/- 0.02 h-1) and slowest on the surface of corn and soybean plants (kcorn = 0.00048 +/- 0.001 h-1 and ksoy = 0.00054 +/- 0.003 h-1). Experiments allowing evaporation during irradiation have intermediate rate constants (e.g., kcorn = 0.082 +/- 0.005 h-1). Finally, identification of photoproducts was also examined on epicuticular waxes of corn and soybean plants for the first time. PMID- 30285551 TI - Comparison between personal sampling methodologies for evaluating diesel particulate matter exposures in mines: submicron total carbon corrected for the adsorption of vapor-phase organic carbon versus respirable total carbon. AB - In the mining industry, personal measurements of elemental and total carbon are frequently used as surrogates of diesel particulate matter (DPM) exposure, and the respirable or submicron fractions are usually measured. However, vapor-phase organic carbon (OC) can be adsorbed in the filters, interfering with total carbon results. This study presents a comparative evaluation between the submicron fraction of DPM concentrations corrected for the adsorption of the vapor-phase OC (dynamic blank), and the respirable fraction of DPM corrected for a field blank. Respirable and submicron fractions of total carbon (TCR and TC1) and elemental carbon (ECR and EC1) concentrations were sampled in parallel, in the workers' breathing zone, in an underground gold mine. A total of 20 full-shift personal samples were taken for each size fraction. Field blanks were collected each day for both the submicron and respirable fractions, while dynamic blank correction was also applied for the submicron fraction. TCR presented a larger and statistically different geometric mean concentration compared to TC1 (98 ug/m3 versus 72 ug/m3; p = 0.01), while the concentrations of ECR and EC1 were not statistically different (58 ug/m3 versus 54 ug/m3; p = 0.74). Average TCR/ECR ratio was 1.7, while the TC1/EC1 ratio was 1.3. In addition, 93% of EC had an aerodynamic size lower than 1 um, while the proportion of TC particles in the submicron fraction was lower (73%). Finally, a similar quantity of OC was found when analysing the dynamic and field blanks of the filters with the submicron fraction selective size (24 ug and 22 ug, respectively). In conclusion, the correction for the vapor phase OC by the dynamic blank was not a significant correction in our study design compared to the field blank samples. This study suggests that the differences in TC may be explained by the different aerodynamic fractions of DPM collected. In addition, elemental carbon measurements did not seem to be extensively affected by the aerodynamic size of the particles collected. PMID- 30285552 TI - Development and validation of a quantitative method for thymidine phosphorylase activity in peripheral blood mononuclear cells. AB - The enzyme thymidine phosphorylase (TP) is important for activation of capecitabine and 5-fluorouracil. Assessment of TP phenotype might be suitable for identification of patients at risk of fluoropyrimidine-induced toxicity. In this paper, we describe the development and validation an assay for TP activity in peripheral blood mononuclear cells (PBMCs). The assay was based on ex vivo conversion of the TP substrate thymidine to thymine. The amount of thymine formed was determined by high-performance liquid chromatography - ultraviolet detection (HPLC-UV) with 5-bromouracil as internal standard. Lymphocytes and monocytes were purified from isolated PBMCs to examine cell-specific TP activity. TP activity in PBMCs demonstrated Michaelis-Menten kinetics. The lower limit of quantification was 2.3 ug PBMC protein and assay linearity was demonstrated up to 22.7 ug PBMC protein. Within-day and between-day precisions were <=9.2% and <=6.0%, respectively. Adequate stability TP activity was demonstrated after long-term storage of PBMC dry pellets and lysates at -80 degrees C. In monocytes, TP activity was approximately 3 times higher than in lymphocytes. Clinical applicability was demonstrated in samples that were collected from five cancer patients. A simple, precise and sensitive HPLC-UV assay for quantification of TP activity in PBMCs was developed that can be applied for clinical research. PMID- 30285553 TI - Parenting school-aged children after the death of a child: A qualitative study on victims' families of the Sewol ferry disaster in South Korea. AB - This study aims to identify parenting experiences after the death of a child. Using interpretive phenomenological analysis, we mapped the experiences of 16 parents with school-aged surviving children after the death of their sibling to the 2014 Sewol ferry disaster in South Korea. Interviews illuminate five master themes of parenting surviving children following a child's death: (a) parental anxiety, (b) conflicts and obstacles in the parent-child relationship, (c) changes in parenting style, (d) striving to support children's grief, and (e) seeking outside help for parenting. Implications for supporting grieving parents and their children are discussed in light of the findings. PMID- 30285554 TI - The prevalence of elder abuse and neglect in Iran: a systematic review and meta analysis. AB - OBJECTIVE: The aim of this study was to estimate the prevalence of elder abuse and neglect in Iran. METHODS: We searched PubMed, Embase, Scopus, and PsycINFO by the end of 2017. The prevalence was calculated based on the percentage or the amount reported in the studies. Heterogeneity was assessed by the I2 statistic, and the data were combined using random effects model. The results were reported as the pooled estimates and the 95% confidence intervals (CIs). The review protocol was registered in PROSPERO (CRD42017070744). RESULTS: A total of 16 studies involving 6,461 participants aged 60 years and over were included. The pooled prevalence for overall elder abuse was 45.7% (95% CI: 27.3-64.1, p < .001). DISCUSSION: The prevalence of elder abuse and neglect is substantial in the Iranian population aged 60 years and over. More research is needed to investigate the actual prevalence of elder abuse at the national level. PMID- 30285555 TI - Health-enhancing physical activity during practice among student football managers at a Division I university. AB - OBJECTIVE: Student football managers have demands on their time that may pose barriers to meeting recommended current physical activity (PA) guidelines. The study sought to assess the amount of PA obtained by student football managers at a NCAA Division I Football university. PARTICIPANTS: Subjects were student football managers (n = 14) with data collected in the fall 2015. METHODS: Participants wore an Omron HJ-720ITFFP pedometer for seven consecutive days during football activities only, while self-reporting their overall PA on day 7. Measures were analyzed using repeated measures and mixed-design ANOVAs. RESULTS: Managers averaged 8474 steps/day for each practice/game. All PA measures significantly varied by day and manager experience. Overall PA equated to 78 hours of walking. CONCLUSIONS: Student football managers easily met and surpassed the recommended aerobic health-enhancing PA guideline. While their manager related PA was 140 minutes per week, other PA allowed them to easily reach significantly healthy levels of PA. PMID- 30285556 TI - Drunkorexia: A new term and diagnostic criteria. AB - Individuals who restrict their caloric intake and/or exercise excessively to mitigate the calories from alcohol consumption may suffer from an eating disorder, substance abuse disorder, or both. While the term "drunkorexia" has been used in both academic articles and popular culture, issues persist with respect to diagnosing and treating this condition. Classifying the behavior as a subcategory of Other Specified Feeding and Eating Disorders (OSFED) would provide patients with an increased likelihood of receiving insurance coverage for this condition. A consistent definition of this behavior and a more medically accurate/appropriate term-such as "alcoholimia"-are both needed to advance treatment and prevention efforts. PMID- 30285557 TI - Lived experience of a child's chronic illness and death: A qualitative systematic review of the parental bereavement trajectory. AB - To understand the lived experience of parents who have lost their child to a chronic life-limiting condition, six major databases were searched by adhering to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Articles were screened for appropriateness using the Sample, Phenomenon of Interest, Design, Evaluation, Research type tool, and relevant qualitative studies were selected for full-text data analysis using Thematic Synthesis. Findings were categorized into 13 themes that were further organized into a four phase trajectory of parental bereavement experience of child loss, namely: Liminal Margin, Holding Space, Navigating Losses, and Reconstructing Lives. The findings are discussed in the light of existing literature with practical recommendations for enhancing parental bereavement support services. PMID- 30285559 TI - Questioning the Value of Fluorodeoxyglucose Positron Emission Tomography for Residual Lesions After Chemotherapy for Metastatic Seminoma: Results of an International Global Germ Cell Cancer Group Registry. AB - PURPOSE: Residual lesions after chemotherapy are frequent in metastatic seminoma. Watchful waiting is recommended for lesions < 3 cm as well as for fluorodeoxyglucose (FDG) positron emission tomography (PET)-negative lesions >= 3 cm. Information on the optimal management of PET-positive residual lesions >= 3 cm is lacking. PATIENTS AND METHODS: We retrospectively identified 90 patients with metastatic seminoma with PET-positive residual lesions after chemotherapy. Patients with elevated alpha-fetoprotein or nonseminomatous histology were excluded. We analyzed the post-PET management and its impact on relapse and survival and calculated the positive predictive value (PPV) for PET. RESULTS: Median follow-up time was 29 months (interquartile range [IQR], 10 to 62 months). Median diameter of the largest residual mass was 4.9 cm (range, 1.1 to 14 cm), with masses located in the retroperitoneum (77%), pelvis (16%), mediastinum (17%), and/or lung (3%). Median time from the last day of chemotherapy to PET was 6.9 weeks (IQR, 4.4 to 9.9 weeks). Post-PET management included repeated imaging in 51 patients (57%), resection in 26 patients (29%), biopsy in nine patients (10%) and radiotherapy in four patients (4%). Histology of the resected specimen was necrosis in 21 patients (81%) and vital seminoma in five patients (19%). No biopsy revealed vital seminoma. Relapse or progression occurred in 15 patients (17%) after a median of 3.7 months (IQR, 2.5 to 4.9 months) and was found in 11 (22%) of 51 patients on repeated imaging, in two (8%) of 26 patients after resection, and in two (22%) of nine patients after biopsy. All but one patient who experienced relapse were successfully treated with salvage therapy. The PPV for FDG-PET was 23%. CONCLUSION: FDG-PET has a low PPV for vital tumor in residual lesions after chemotherapy in patients with metastatic seminoma. This cautions against clinical decisions based on PET positivity alone. PMID- 30285558 TI - Cost-Effectiveness Analysis of Brentuximab Vedotin With Chemotherapy in Newly Diagnosed Stage III and IV Hodgkin Lymphoma. AB - PURPOSE: In a recent randomized, open-label trial (ECHELON-1), brentuximab vedotin (BV) combined with doxorubicin, vinblastine, and dacarbazine (AVD+BV) decreased the risk of progression in adults diagnosed with stage III or IV Hodgkin lymphoma (HL) compared with standard bleomycin-containing chemotherapy (doxorubicin, bleomycin, vinblastine, and dacarbazine [ABVD]). However, the cost effectiveness of incorporating BV (US$6,970 per 50-mg vial) into the first-line setting is unknown. PATIENTS AND METHODS: We constructed a Markov decision analytic model to measure the costs and clinical outcomes for AVD+BV compared with ABVD as first-line therapy in a cohort of patients with stage III or IV HL. Transition probabilities were estimated from ECHELON-1 by fitting parametric survival distributions. Lifetime direct health care costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs) were calculated for AVD+BV compared with ABVD from a US payer perspective. Our model was also used to estimate BV price reductions that would achieve more favorable cost effectiveness under indication-specific pricing. RESULTS: AVD+BV was associated with an improvement of 0.56 QALYs compared with treatment with standard ABVD. However, incorporating BV into first-line therapy led to significantly higher lifetime health care costs ($361,137 v $184,291), causing the ICER for AVD+BV to be $317,254 per QALY. If indication-specific pricing were implemented, acquisition costs for BV used in the first-line setting would need to be reduced by 56% to 73% for ICERs of $150,000 to $100,000 per QALY, respectively. CONCLUSION: Substituting BV for bleomycin during first-line therapy for stage III or IV HL is unlikely to be cost effective under current drug pricing. Should indication-specific pricing be implemented, significant price reductions for BV used in the first-line setting would be needed to reduce ICERs to more widely acceptable values. PMID- 30285560 TI - Chemotherapy-Free Initial Treatment of Advanced Indolent Lymphoma Has Durable Effect With Low Toxicity: Results From Two Nordic Lymphoma Group Trials With More Than 10 Years of Follow-Up. AB - PURPOSE: For indolent lymphoma, the optimal timing, sequence, and choice of therapeutic regimens remain a matter of debate. In two Nordic Lymphoma Group randomized trials, symptomatic or clearly progressing patients were treated first line with a rituximab-containing regimen without chemotherapy. The purpose of this study was to assess long-term survival, risk of transformation, and need of new therapies. METHODS: Data were collected at cross-sectional follow-up for 321 patients with indolent lymphoma (84% with follicular lymphomas [FL]) included in one of two Nordic Lymphoma Group trials (accrual 1998 to 1999 and 2002 to 2008). All patients received first-line therapy with one or two cycles of four weekly infusions of rituximab 375 mg/m2, and 148 were randomly allocated to the addition of interferon alfa-2a. Follow-up data were retrieved from initial trial databases and medical records on repeated clinical evaluations. RESULTS: At the end of follow-up, 73% of patients were alive, with a median follow-up after random assignment of 10.6 years. Among all, 36% (38% with FL) had never needed chemotherapy. For patients with FL who required new therapy within 24 months because of early disease progression, the 10-year survival rate was 59% versus 81% for those with longer remission. Interferon was not shown to improve long term outcome. Transformation was diagnosed in 20% of all patients (2.4% per person-year) and in 18% with FL. An additional malignancy was found in 12%. CONCLUSION: Approximately one third of patients with symptomatic indolent lymphoma (30% with FL, 23% without FL) did not need new therapy in the long term after first-line rituximab without chemotherapy. In the entire cohort, 10-year survival was excellent with no major safety issues, which suggests that chemotherapy can be delayed safely in the majority of patients. PMID- 30285561 TI - Reliance agreements and single IRB review of multisite research: Concerns of IRB members and staff. AB - The new National Institutes of Health (NIH) Policy on the Use of a Single Institutional Review Board (sIRB) for Multi-Site Research was adopted primarily to simplify and speed the review of complex multisite clinical trials. However, speeding review requires overcoming a number of obstacles. Perhaps the most substantial obstacle is the time and effort needed to develop reliance agreements among the participating sites. We conducted 102 semistructured interviews with sIRB personnel, including directors, chairs, reviewers, and staff, from 20 IRBs that acted as sIRBs for multisite research, including 6 commercial/independent sIRBs, and 10 university-based academic and 4 federal sIRBs. Almost without exception, the interviewees agreed that reliance agreements were complex, difficult to develop, and time-consuming. A major problem for relying sites was that different agreements specified different responsibilities for the relying sites. Attitudes differed about whether these problems will be resolved as IRB staff and managers become more experienced with sIRBs. However it is clear that the process of developing reliance agreements must be simplified. Federal assistance in standardizing at least some sections of reliance agreements might reduce the difficulties involved. PMID- 30285562 TI - Understanding factors related to nonsmoking intention among college students. AB - OBJECTIVE: While cigarette smoking in the United States has declined, the age range of smoking initiation has risen to include young adults. This study investigated the relationship of Theory of Planned Behavior constructs (TPB; attitudes, subjective norms, and perceived behavioral control [PBC]) to nonsmoking intention among college students. PARTICIPANTS: Participants were 619 students at a Southeastern US university (69.8% female, 70.8% <= age 21, and 73.5% white). METHODS: Students were recruited by email in March 2013 to participate in an online TPB-based questionnaire. RESULTS: Future-oriented attitudes and PBC predicted higher nonsmoking intention; subjective norms did not. Moderator analyses indicated injunctive norms were more influential for occasional smokers and PBC was less influential. CONCLUSIONS: Findings suggest TPB is useful in predicting nonsmoking intention, but differentially for nonsmokers and occasional smokers. Future work should consider the health-related utility of future-oriented attitudes toward nonhealth domains and the differing beliefs of occasional smokers. PMID- 30285563 TI - Understanding stress as an impediment to academic performance. AB - OBJECTIVES: Stress is the most commonly reported impediment to academic performance among college students. The objectives of this study were to examine the accuracy of these perceptions, identify demographic and psychosocial factors that distinguished among students who differed in perceptions of how stress affected their performance, and assess the relations between these factors and grade point average (GPA). PARTICIPANTS: Undergraduate students (N = 8,997) from 20 Midwestern schools. METHODS: Participants completed online surveys during February-March 2015 that assessed perceived impediments to academic performance, cumulative GPA, demographic information, and psychosocial factors. RESULTS: Students who reported that stress affected their performance had lower GPAs, and reported more stress and lower coping self-efficacy, resilience, and social support. Male, heterosexual, and ethnic-minority students were less likely to report having stress (but did not have higher GPAs). CONCLUSION: Stress reduction interventions should target psychosocial factors related to perceiving stress as an impediment and to poorer performance. PMID- 30285564 TI - Actual and simulated weather data to evaluate wet bulb globe temperature and heat index as alerts for occupational heat-related illness. AB - Heat stress occupational exposure limits (OELs) were developed in the 1970s to prevent heat-related illnesses (HRIs). The OELs define the maximum safe wet bulb globe temperature (WBGT) for a given physical activity level. This study's objectives were to compute the sensitivity of heat stress OELs and determine if Heat Index could be a surrogate for WBGT. We performed a retrospective analysis of 234 outdoor work-related HRIs reported to the Occupational Safety and Health Administration in 2016. Archived NOAA weather data were used to compute each day's maximum WBGT and Heat Index. We defined the OELs' sensitivity as the percentage of incidents with WBGT > OEL. Sensitivity of the OELs was between 88% and 97%, depending upon our assumption about acclimatization status. In fatal cases, the OELs' sensitivity was somewhat higher (92% to 100%). We also computed the sensitivity of each possible Heat Index discrimination threshold. A Heat Index threshold of 80 degrees F (26.7 degrees C) was exceeded in 100% of fatalities and 99% of non-fatal HRIs. In a separate analysis, we created simulated weather data to assess associations of WBGT with Heat Index over a range of realistic outdoor heat conditions. These simulations demonstrated that for a given Heat Index, when radiant heat was included, WBGT was often higher than previously reported. The imperfect correlation between WBGT and Heat Index precluded a direct translation of OELs from WBGT into Heat Index. We conclude that WBGT-based heat stress exposure limits are highly sensitive and should be used for workplace heat hazard assessment. When WBGT is unavailable, a Heat Index alert threshold of approximately 80 degrees F (26.7 degrees C) could identify potentially hazardous workplace environmental heat. PMID- 30285565 TI - Women's knowledge about risk factors of breast cancer in a Brazilian community. AB - Knowledge about risk factors for breast cancer was identified as an important variable that affects women's avoidance behavior and their screening performance. The present study assessed women's knowledge about risk factors and associated socio-economic variables. Data from 417 women aged 20-86 years were obtained in Caico, Rio Grande do Norte, Brazil. In agreement with the recognition of 26 potential risk factors and prevention behaviors, two groups with good (N = 203) and poor (N = 214) knowledge were formed, respectively. Having a close relative with cancer remained the unique significant variable in the adjusted model. Women without any close relative with cancer, were 1.54 (95% confidence interval [CI] 1.036-2.288) times as likely to have poor knowledge, compared to women who had a close relative with cancer (p = 0.033). Other socio-economic variables, including income, employment status and educational level had no significant association with knowledge (p = 0.450, p = 0.914, p = 0.639, respectively). Of 417 women, 302 (72.42%), 339 (81.29%), and 309 (74.10%), respectively, did not identify "physical inactivity," "overweight after menopause," and "no breastfeeding of children" as risk factors. Knowledge could help to avoid risk factors and motivate prevention behavior. Information about risk factors should be disseminated in health campaigns.

AB - Improvements in the diagnosis and disclosure of dying mean that nowadays dying people typically live with an awareness of their status for longer than they have previously. However, little is known regarding how transitions between living and dying roles occur during this time. In this grounded theory study, we investigated role transitions at end-of-life. We found that dying people periodically foreground and background living and dying selfhoods, focus on living day-by-day and goal-by-goal and reframe dying roles with an orientation to living. We argue that with better understanding of role transitions at end-of life more compassionate and responsive care becomes possible. PMID- 30285567 TI - Mind and mourning: The primacy of "we" in complicated grief. AB - Standard models of complicated grief rely on a self-other divided mind that reflects the physical separateness of individuals. In these models, grief persists for those mourners who cannot reorganize self-and-other mental representations or adapt to identity changes after loss. However, advances in cognitive science indicate that relationships are often processed via distributed social-cognitive coding whereby individuals together form a psychologically extended common mind. I propose a novel "we" hypothesis in which shared representations, rather than self-other distinctions, shape the mind for a subgroup of mourners with complicated grief. Recognition of "we-experiences" in mourning can enhance grief theory, research, and practice.

AB - OBJECTIVE: This investigation longitudinally examined the participation of Black college students in the American College Health Association?s National College Health Assessment (ACHA-NCHA). PARTICIPANTS: All respondents to ACHA-NCHA from the years 2008, 2011, & 2014 were included in the analysis. METHODS: This study compared the descriptive demographic student characteristics from the 2008, 2011, & 2014 ACHA-NCHA data to the National Center for Education Statistics (NCES) college enrollment for the corresponding years. RESULTS: Despite constituting 14.5% of the total enrollment in 4-year universities and colleges from 2005 to 2013, Black students represented about 7% of the ACHA-NCHA respondents. CONCLUSION: Having a sample lacking valid representation of minorities can further lead to biased and flawed assumptions. Therefore, organizations such as ACHA should make concerted efforts to gather data that is reflective of national enrollment rates. PMID- 30285569 TI - Physical Activity, Health-Related Fitness, and Classroom Behavior in Children: A Discriminant Function Analysis. AB - PURPOSE: The purpose of this study was to examine the predictive relationship among physical activity, health-related fitness, and on-task classroom behavior in children using a discriminant function analysis. METHOD: Participants were a convenience sample of children (N = 533; Mage = 8.8 +/- 1.9 years) recruited from 77 1st- through 5th-grade classrooms at 3 low-income schools in a capital city in the Southwest United States. Percent of the school day spent in sedentary behavior (%SED), moderate-to-vigorous physical activity (%MVPA), and health related fitness scores (body mass index [BMI] and Progressive Aerobic Cardiovascular Endurance Run [PACER] laps) were assessed during school hours. Classrooms were observed for on-task behavior during the academic year with the use of 5-s momentary time sampling methodology. A discriminant function analysis was performed using a binary on-task behavior outcome, stratified by an 80% on task behavior cut point. RESULTS: The results yielded 1 function (r2 = .26, F = 13.1) explaining approximately one quarter of the total variance. The standardized function coefficients were -.29, .29, -.48, and .48 for %SED, %MVPA, BMI, and PACER laps, respectively. The sensitivity and specificity of the derived function for classifying a child into an on-task or off-task classroom were .79 and .73, respectively. Children who belonged to classrooms that achieved 80% on task behavior displayed shorter times in sedentary behaviors (d = 1.01), lower BMI (d = 0.13), and higher PACER scores (d = 0.22) compared with children who belonged to off-task classrooms. CONCLUSION: School-day physical activity behaviors and health-related fitness scores can moderately discriminate children who belong to classrooms from low-income schools that are categorized as being sufficiently on task. PMID- 30285570 TI - Authenticity at Work: A Matter of Fit? AB - Authenticity at work refers to the extent to which a worker feels in touch with their true self while at work. At first sight this concept seems to overlap with the concept of person-environment (P-E) fit, that is, the degree to which an individual experiences good fit with their work environment. Drawing on a sample of 867 Dutch gifted workers, structural equation modeling was used to investigate (i) whether authenticity at work and P-E fit can be distinguished, and (ii) how authenticity at work and P-E fit were associated with employee well-being. As expected, confirmatory factor analysis revealed that authenticity at work and P-E fit were distinct from each other. Moreover, the mediated effect of authenticity at work was stronger for two negative forms of well-being (burnout and boredom) than for two positive forms of well-being (work engagement and job satisfaction). The theoretical and practical implications of these findings are discussed, especially focusing on the distinction between authenticity and P-E fit. PMID- 30285571 TI - Predictors of Therapeutic Outcome to Nucleotide Reverse Transcriptase Inhibitor in Hepatitis B Patients. AB - Hepatitis B is a clinically important public health issue. Infection leads to hepatocellular carcinoma. Therefore, patients need antiviral therapy for prolonged period to prevent the complication of the disease. Data concerning chronic hepatitis B (CHB) patients with high hepatitis B virus (HBV) DNA are limited. The aim of the study was to check the efficacy of the nucleoside reverse transcriptase inhibitors (tenofovir) in terms of suppression of HBV DNA. The secondary end point in the study is to evaluate trends of predictive variables that predict outcome of treatment. In this specific study, we evaluated 140 CHB male and female patients, of these 110 completed 48 weeks of treatment. On the basis of hepatitis B e antigen (HBeAg), patients were stratified; HBV DNA and hepatitis B surface antigen (HBsAg) levels were measured along with liver function tests. All enrolled patients were given tenofovir disoproxil fumarate 300 mg daily before breakfast. Overall, 69.1% of patients showed virologic response. HBeAg-negative patient group showed 68% viral suppression and HBeAg positive patient group showed 45.9% over 24 months of treatment, while at 48 months it was shown to be 76.7% and 54.1%, respectively. None of the patients suffered HBsAg loss during the 48 months. Baseline high HBV DNA level was found as a significant predictor of response (OR, 1.9; 95% CI = 1.23-3.9, p = 0.005). None of the patients observed had serious adverse events. Mutations in the RT region of polymerase gene are shown to be associated with resistance to antiviral drugs. Among patients suffering with chronic HBV infection, HBeAg-negative patient group have better virologic response as compared with HBeAg-positive group. Higher concentration of HBV DNA at baseline has negative prediction for sustained viral suppression. The A-B motif interdomain rtL122F mutation was found in nonresponder patients in our study. Another mutation rtN248H observed in E motif considered to have effect on DNA primer grip, which forms part of binding pocket. PMID- 30285572 TI - Own-Age Bias and Positivity Effects in Facial Recognition. AB - Background/Study Context - In the current study, we evaluated two age-related differences in recognition memory: the own-age bias, wherein older and younger adults best recognize those of their own age group, and an age-related positivity effect, wherein older adults recall positive emotional information better than negative information relative to younger adults. We sought to extend previous research that jointly investigated these variables in recognition memory. Methods - Younger (age 18 - 27) and older (age 62 - 80) adults completed an incidental encoding task on a sequence of 50 positive, negative, or neutrally valenced images of older and younger adult faces. After a distractor task, participants made forced-choice recognition judgments and rated their decision confidence for images that were repeated with the same or a different emotional expression, and for novel, previously unseen faces. Results - Older and younger adults' recognition discriminability did not differ significantly between age groups. Notably, the data indicated an own-age bias in young adults, but not in older adults, and both age groups' recognition accuracy was greatest for faces that had originally been shown with a positive emotional expression. Conclusion - To our knowledge, this research is the first to demonstrate an own-age recognition bias in younger adults for emotional faces. Although our predictions of a differential impact by emotional faces on recognition of same and other-age faces were not supported, we identify a number of factors that contextualize these findings in the recent literature. PMID- 30285573 TI - An application of the theory of normative social behavior to bystander intervention for sexual assault. AB - OBJECTIVE: Given the high prevalence of sexual assault on U.S. college campuses, the current study examines predictors of college students' intentions to intervene to prevent sexual assault through the lens of the theory of normative social behavior (TNSB). PARTICIPANTS: One hundred eighty-six undergraduate students age 18-25 were recruited from an introductory course at a large Midwestern university. METHODS: Data were collected through an online survey during the 2015-2016 academic year. RESULTS: Results indicated that descriptive norms, injunctive norms, and outcome expectations had direct positive effects on behavioral intention. However, no direct effect of group identity on intention was found. In addition to these main effects, an interaction between descriptive and injunctive norms was also observed. CONCLUSIONS: The results of the current study speak to theoretical questions surrounding the nature of TNSB variables, as well as several practical implications for coordinated efforts to promote bystander intervention on college campuses. PMID- 30285574 TI - Nutritional Risk among Congregate Meal Site Participants: Benefits of a SNAP-Ed Program. AB - This study examined the impact of the Supplemental Nutrition Assistance Program Education (SNAP-Ed) program Fresh Conversations (FC) on the nutritional risk (NR) of older adults (OAs). A convenience sample of OAs (207 Treatment, 148 Control) completed questionnaires comprised of validated measures to assess NR, barriers to healthy eating self-efficacy (SE), food safety behaviors (FSB), and food security (FS) at three-time points over 9 months. Participants were mostly white (92.4%), older (age 81+ years, 40.1%), widowed (52.4%), and females (75.2%). Independent t-tests identified baseline differences among groups. Analysis of covariance assessed group changes at each time point for each measure. Block regression determined which variables influence baseline NR. Baseline NR risk was significantly predicted by SE (beta = 0.21), education (beta = 0.19) and age (beta = 0.14) (p < 0.05). NR improvement was significantly higher for treatment group participants who attended four or more FC sessions than for the control group (p = .04) when controlling for the effects of gender (p = .061) and SE (p = .098). PMID- 30285575 TI - Exploring suicide-related disclosure motivation and the impact on mechanisms linked to suicide. AB - Suicide-related disclosure enables improved risk management but disclosure motivations are understudied. This study identified reasons for and against disclosing suicidal thoughts and examined their link to future disclosure and interpersonal needs among 44 people receiving psychiatric care. The most endorsed reasons for disclosure (approach-motivations) included help-seeking, shared background, and catharsis. The most endorsed reasons against disclosure (avoidance-motivations) included fear of rejection, shame, and hospitalization. Higher mean approach motivation was associated with more disclosure intent and less burdensomeness. No associations with avoidance motivation were observed. Programming that seeks to orient people toward approach motivation holds promise for attenuating suicide risk. PMID- 30285576 TI - Effectiveness of tacrolimus on IgG4-related disease. PMID- 30285577 TI - Contingent Attentional Engagement: Stimulus- and Goal-Driven Capture Have Qualitatively Different Consequences. AB - We examined whether shifting attention to a location necessarily entails extracting the features at that location, a process referred to as attentional engagement. In three spatial-cuing experiments ( N = 60), we found that an onset cue captured attention both when it shared the target's color and when it did not. Yet the effects of the match between the response associated with the cued object's identity and the response associated with the target (compatibility effects), which are diagnostic of attentional engagement, were observed only with relevant-color onset cues. These findings demonstrate that stimulus- and goal driven capture have qualitatively different consequences: Before attention is reoriented to the target, it is engaged to the location of the critical distractor following goal-driven capture but not stimulus-driven capture. The reported dissociation between attentional shifts and attentional engagement suggests that attention is best described as a camera: One can align its zoom lens without pressing the shutter button. PMID- 30285578 TI - T-lymphocyte-specific knockout of IKK-2 or NEMO induces Th17 cells in an experimental nephrotoxic nephritis mouse model. AB - Experimental nephrotoxic serum nephritis (NTN) is a model for T-cell-mediated human rapid progressive glomerulonephritis. T-cell receptor stimulation involves intracellular signaling events that ultimately lead to the activation of transcription factors, such as NF-kappaB. We explored the involvement of the NF kappaB components IKK-2 and NEMO in NTN, by using cell-specific knockouts of IKK 2 and NEMO in CD4+ T lymphocytes. Our results demonstrate that although the course of disease was not grossly altered in CD4xIKK2Delta and CD4xNEMODelta animals, renal regulatory T cells were significantly reduced and T helper (Th)1 and Th17 cells significantly increased in both knockout mouse groups. The expression of the renal cytokines and chemokines IL-1beta, CCL-2, and CCL-20 was also significantly altered in both knockout mice. Lymphocyte transcriptome analysis confirmed the increased expression of Th17-related cytokines in spleen CD4+ T cells. Moreover, our array data demonstrate an interrupted canonical NF kappaB pathway and an increased expression of noncanonical NF-kappaB pathway related genes in nephritic CD4xNEMODelta mice, highlighting different downstream effects of deletion of IKK-2 or NEMO in T lymphocytes. We propose that better understanding of the role of IKK-2 and NEMO in nephritis is essential for the clinical application of kinase inhibitors in patients with glomerulonephritis.

PMID- 30285579 TI - Tomatidine suppresses osteoclastogenesis and mitigates estrogen deficiency induced bone mass loss by modulating TRAF6-mediated signaling. AB - Postmenopausal osteoporosis is initiated by estrogen withdrawal and is characterized mainly by overactivated osteoclastic bone resorption. Targeting TNF receptor-associated factor 6 (TRAF6) or its downstream signaling pathways to modulate osteoclast formation and function is an appealing strategy for osteoclast-related disorders. In the present study, we determined the effect of tomatidine, a steroidal alkaloid derived from Solanaceae, on the formation and function of receptor activator of NF-kappaB (RANK) ligand-induced osteoclasts and the underlying mechanism. Tomatidine inhibited osteoclast formation in a dose dependent manner and decreased the expression of osteoclast marker genes. Actin ring formation and osteoclastic bone resorption were attenuated in the presence of tomatidine in vitro. Eight weeks after ovariectomy, tomatidine prevented estrogen deficiency-induced bone loss and restored the mechanical properties of the femur. At the molecular level, tomatidine abrogated phosphorylation of c-Jun N-terminal kinase (JNK)/p38, NF-kappaB, and protein kinase B (Akt) pathway proteins by suppressing RANK expression, inhibiting the binding of TRAF6 to RANK, and downregulating the osteoclastogenesis marker-related protein expression. In summary, these data demonstrated that tomatidine attenuated osteoclast formation and function by modulating multiple TRAF6-mediated pathways. Therefore, tomatidine could be a novel candidate for the treatment of osteoclast-related disorders, including osteoporosis.-Hu, B., Sun, X., Yang, Y., Ying, Z., Meng, J., Zhou, C., Jiang, G., Li, S., Wu, F., Zhao, X., Zhu, H., Wu, H., Cai, X., Shi, Z., Yan, S.

PMID- 30285580 TI - Mapping the minimum domain of the fibronectin binding site on transglutaminase 2 (TG2) and its importance in mediating signaling, adhesion, and migration in TG2 expressing cells. AB - The interaction between the enzyme transglutaminase 2 (TG2) and fibronectin (FN) is involved in the cell-matrix interactions that regulate cell signaling, adhesion, and migration and play central roles in pathologic conditions, particularly fibrosis and cancer. A precise definition of the exact interaction domains on both proteins could provide a tool to design novel molecules with potential therapeutic applications. Although specific residues involved in the interaction within TG2 have been analyzed, little is known regarding the TG2 binding site on FN. This site has been mapped to a large internal 45-kDa protein fragment coincident with the gelatin binding domain (GBD). With the goal of defining the minimal FN interacting domain for TG2, we produced several expression constructs encoding different portions or modules of the GBD and tested their binding and functional properties. The results demonstrate that the I8 module is necessary and sufficient for TG2-binding in vitro, but does not have functional effects on TG2-expressing cells. Modules I7 and I9 increase the strength of the binding and are required for cell adhesion. A 15-kDa fragment encompassing modules I7-9 behaves as the whole 45-kDa GBD and mediates signaling, adhesion, spreading, and migration of TG2+ cells. This study provides new insights into the mechanism for TG2 binding to FN.-Soluri, M.

PMID- 30285581 TI - Decrease in alphabeta/gammadelta T-cell ratio is accompanied by a reduction in high-fat diet-induced weight gain, insulin resistance, and inflammation. AB - The implication of alphabeta and gammadelta T cells in obesity-associated inflammation and insulin resistance (IR) remains uncertain. Mice lacking gammadelta T cells show either no difference or a decrease in high-fat diet (HFD) induced IR, whereas partial depletion in gammadelta T cells does not protect from HFD-induced IR. alphabeta T-cell deficiency leads to a decrease in white adipose tissue (WAT) inflammation and IR without weight change, but partial depletion of these cells has not been studied. We previously described a mouse model overexpressing peroxisome proliferator-activated receptor beta (PPAR-beta) specifically in T cells [transgenic (Tg) T-PPAR-beta] that exhibits a partial depletion in alphabeta T cells and no change in gammadelta T-cell number. This results in a decreased alphabeta/gammadelta T-cell ratio in lymphoid organs. We now show that Tg T-PPAR-beta mice are partially protected against HFD-induced weight gain and exhibit decreased IR and liver steatosis independently of animal weight. These mice display an alteration of WAT-depots distribution with an increased epididymal-WAT mass and a decreased subcutaneous WAT mass. Immune cell number is decreased in both WAT-depots, except for gammadelta T cells, which are increased in epididymal-WAT. Overall, we show that decreasing alphabeta/gammadelta T-cell ratio in WAT-depots alters their inflammatory state and mass repartition, which might be involved in improvement of insulin sensitivity.-Le Menn, G., Sibille, B., Murdaca, J., Rousseau, A.-S., Squillace, R., Vergoni, B., Cormont, M., Niot, I., Grimaldi, P. A., Mothe-Satney, I., Neels, J. G. Decrease in alphabeta/gammadelta T-cell ratio is accompanied by a reduction in high-fat diet-induced weight gain, insulin resistance, and inflammation. PMID- 30285582 TI - KOH modified Thevetia peruviana shell activated carbon for sorption of dimethoate from aqueous solution. AB - Modified Thevetia peruviana shell activated carbon for sorption of dimethoate from aqueous solution derived with potassium hydroxide (KOH) was studied at different concentrations for its potential application in water treatment. The batch sorption was investigated using dimethoate solution of 10-100 mg/L concentrations. Proximate analysis was determined and changes on the surfaces and structure of the TPS were characterized after chemical activation with KOH using XRD, FTIR, SEM-EDAX, pHpzc, BET. The quantum chemical calculation for dimethoate yielded molecule associated energies of -9.8421 (HOMO) and -2.3879 (LUMO) and a total energy of -53,376.2. The kinetic of the sorption was modeled which indicated the sorption equilibrium time as 90 min and pseudo-first order kinetics model showing R2 = 0.994 provided a better description of the process. Analysis of sorption equilibrium revealed that the data fitted well to Freundlich sorption isotherm model (R2 = 0.966), indicating multi-layer sorption of dimethoate on the surface of sorbent. The sorption of dimethoate onto KOHTPS shows 92.60% removal efficiency. PMID- 30285583 TI - Adverse Childhood Experiences and Healthcare Costs in Adult Life. AB - The current study aims to present the prevalence of adverse childhood experiences and examine the healthcare costs associated with primary, allied, and specialist healthcare services. The Australian Longitudinal Study on Women's Health is a general health survey of four nationally representative age cohorts. The current study uses 20 years of survey and administrative data (1996-2015) from the cohort born 1973-1978. Overall, 41% of women indicated at least one category of childhood adversity. The most commonly reported type of childhood adversity was having a household member with a mental illness (16%), with the most commonly reported ACES category being psychological abuse (17%). Women who had experienced adversity in childhood had higher healthcare costs than women who had not experienced adversity. The healthcare costs associated with experiences of adversity in childhood fully justify a comprehensive policy and practice review. PMID- 30285584 TI - Interpersonal theory dimensions facilitate posttraumatic growth among suicide loss survivors: An attachment perspective. AB - Many studies have highlighted the deleterious psychological impact of suicide on bereaved individuals. We examined the psychological processes facilitating posttraumatic growth (PTG) among 124 suicide-loss survivors, focusing on attachment styles, perceived burdensomeness, and thwarted belongingness. Securely attached individuals achieved higher PTG than insecurely attached individuals. Perceived burdensomeness and thwarted belongingness both mediated and moderated the associations between attachment and PTG. Anxiously or avoidantly attached individuals who also had a high level of perceived burdensomeness were the least likely to achieve PTG. Thus, these individuals may derive particular benefit from attachment-based therapeutic interventions focusing on interpersonal relationships. PMID- 30285585 TI - Predictive factors for radiographic progression of large joint damage in patients with rheumatoid arthritis treated with biological disease-modifying antirheumatic drugs (bDMARDs): results of 3 to 4 years of follow-up. AB - OBJECTIVES: Little information is available regarding long-term follow-up of radiographic progression of damage (RPD) to large joints during treatment of rheumatoid arthritis (RA) with biological disease-modifying antirheumatic drugs (bDMARDs). We evaluated 3- to 4-year follow-up results and the associations between RPD and patient background and Larsen grade (LG) of joints. METHODS: Seventy-one RA patients receiving bDMARDs for 3 to 4 years or who achieved bDMARD free status were included. The mean age and disease duration at the start of bDMARDs were 62.4 years and 10.8 years, respectively. A total of 314 joints, including shoulders, elbows, hips, knees, and ankles, were evaluated to determine whether RPD was present by comparing radiographs before and after treatment. RESULTS: RPD was observed in 24 patients (33.8%) and 34 joints (10.8%). Joints with a LG of III or higher had significantly higher rates of RPD than those with LGs I and II. Multivariate logistic regression analysis revealed that stage and health assessment questionnaire (HAQ) score at 18-month were independent risk factors for RPD (cut-off value: 2.5, odds ratio: 7.222 for stage; cut-off value: 0.9375, odds ratio: 6.278 for HAQ at 18-month). CONCLUSIONS: Stage, HAQ at 18 month, and LG at the start of bDMARDs were predictive of RPD after 3 to 4 years. bDMARDs should be started before both stage and LG exceed III and the therapeutic strategy should be determined so that HAQ does not exceed 1.0 during treatment.

AB - The primary purpose of this study was to identify themes that are consistent across veterinary internship applicants' personal statements and that are correlated with the statements' perceived overall quality. A secondary purpose was to investigate the reliability in personal statement quality scoring among six experienced internship candidate evaluators. One hundred applications to the University of Georgia Small Animal Rotating Internship program were evaluated. Each evaluator wrote a description of what he or she values in personal statements and his or her beliefs about content and presentation in high- and low quality statements. After statement de-identification, each evaluator reviewed 15 randomly selected personal statements from internship applicants and assigned each a score ranging from 1 to 4 according to the following criteria: 1 = would not rank for an internship; 2 = would rank in bottom third; 3 = would rank in middle third; and 4 = would rank in the top third. A subset of these scored personal statements was chosen for qualitative analysis. A qualitative document analysis using grounded theory was performed for both the evaluators' descriptions of preferences in personal statements and the subset of personal statements. Agreement among evaluators' assigned scores was slight (Fleiss's kappa = 0.11). Analysis of the evaluator statements and the scored candidate statements indicated that important factors in a personal statement include the applicant's ability to articulate experiences, to convey maturity, to demonstrate understanding of what an internship entails, and to describe reasons for pursuing an internship. PMID- 30285590 TI - Effect of Different Instructional Methods on Contamination and Personal Protective Equipment Protocol Adherence among Veterinary Students. AB - Proper use of personal protective equipment (PPE) is crucial to prevent disease spread. Recent studies in human medicine have shown disconcerting inconsistencies in the use of PPE in hospital wards. In this study, we compared the effect of three instructional methods for PPE use on contamination and protocol adherence among veterinary students. Students were divided into three groups according to the instructional method to which they had access (instructional video, wall chart, or both). They underwent an isolation exercise consisting of donning, patient examination (mock patient prepared with contamination marker), and doffing. Student contamination after the exercise was evaluated using UV light. Videos of student performance were reviewed for errors committed. Results showed that the number of students with contamination was higher in the group who only had access to video instruction than in the two other groups. The number of students with contamination on forearms, hands, and wrists was higher in the group who only had access to charts. Disinfecting gloves between doffing steps was the most frequently omitted step. The number of students who touched the environment with unprotected areas of their bodies was higher in the group who only had access to video instruction than in the other two groups. In conclusion, video instruction was less effective in achieving PPE protocol adherence among veterinary students than was instruction with a chart or chart-video combination. Incorporating video instruction as part of the instructions may be valuable to reinforce individual steps of donning and doffing. PMID- 30285591 TI - What are Employers Looking for in New Veterinary Graduates? A Content Analysis of UK Veterinary Job Advertisements. AB - As veterinary educators, we have a responsibility to ensure that our graduates are prepared for working life. Veterinary practices, like any other businesses, rely on good employees, and the implications of a poor match between newly employed veterinarian and employing practice could be extremely costly in terms of personal well-being and enjoyment of work as well as the time, financial, and goodwill costs of high staff turnover for the practice. Contemporary veterinary curricula encompass a range of teaching to complement the clinical content; including communication, teamwork, problem solving, and business skills, to support good practice and increase the employability of new graduates. Previous studies have examined the qualities required of early career veterinarians as viewed by educators, recent graduates, pet owners, and practitioners; however, nobody has previously constructed a picture of the employment market for new veterinary graduates by exploring the nature of its recruitment advertising. Three months of UK veterinary job advertisements were examined. Content analysis yielded 10 distinct characteristics desired by employers of early career veterinarians. The most common by far was "enthusiasm," followed by an interest in a particular area of practice, being an "all-rounder" (i.e., having a broad range of skills), demonstrating good communication skills, teamwork, client care, and independence, as well as being caring, ambitious, and having high clinical standards. While several of these qualities are expected and are specifically taught in veterinary school, the dominance of "enthusiasm" as a specifically desired trait raises interesting questions about the characteristics of veterinary students who we are supporting, encouraging, or maybe even suppressing, during veterinary training. PMID- 30285592 TI - Evaluating Dog and Cat Owner Preferences for Calgary-Cambridge Communication Skills: Results of a Questionnaire. AB - Veterinary client retention by companion animal practices is influenced by whether the client feels connected to the healthcare provider. Effective communication between the veterinarian and the client facilitates that connection. To prepare new graduates for success in clinical practice, many colleges of veterinary medicine are now incorporating communication into the curriculum to emphasize its importance in establishing and maintaining the veterinarian-client relationship. A 2016 focus group study by Englar et al. evaluated dog and cat owner communication preferences for Calgary-Cambridge Guide (CCG) communication skills and concluded that dog and cat owners may have different communication needs. This study was conducted to confirm whether species-based communication preferences exist among veterinary clients. A questionnaire was distributed online and on-site, within veterinary teaching hospitals and private practices. Based upon 215 submissions from dog owners and 166 from cat owners, the communication preferences of dog and cat owners overlap. Both dog and cat owners prioritize reflective listening as the most important foundational CCG communication skill, and both prioritize asking permission as the most important core CCG skill. However, dog owners valued open-ended questions more than cat owners, and cat owners valued empathy more than dog owners. Survey limitations were largely demographic: participants were predominantly female and between the ages of 18-40 years. Survey data may therefore not be representative of the perspective of males and/or those >40 years of age. PMID- 30285593 TI - Educators' Perspectives on Animal Welfare and Ethics in the Australia and New Zealand Veterinary Curricula. AB - The current study was designed to explore the importance that veterinary science educators in Australia and New Zealand universities assign to animal welfare and ethics (AWE) topics as Day One/Initial Competences for new graduates. An online questionnaire was deployed in parallel with an equivalent study of veterinary science students at these educators' schools. Responses were received from 142 educators (51% females n=72 and 49% males n=70), representing an overall participation rate of 25%. Questions were clustered according to seven areas of veterinary employment: general practice, production animals, companion animals, wild animals, aquatic animals, animals kept for scientific purposes, and animals used in sport and recreation. The most highly rated topics for each of these clusters were: professional ethics in general practice, euthanasia in companion animals, strategies to address painful husbandry procedures in production animals, veterinarians' duties to wild animals in animals in the wild, aquatic animal health and welfare issues in aquatic animals; competence in the 3Rs (replacement, refinement and reduction) in animals kept for scientific purposes, and responsibilities of ownership in sport and recreation. Female educators rated many of the topics as significantly more important than did their male counterparts. Educators teaching one or more ethics-related subjects were less likely to rate neutering and euthanasia as important as those not teaching these subjects. The educators' focus on practical issues clashes with a perceived need for veterinarians to actively embrace animal ethics. Overall, the perspectives of these educators should be carefully considered as they are likely to influence student attitudes. PMID- 30285594 TI - Evaluation of Two Training Methods for Teaching the Abdominal Focused Assessment with Sonography for Trauma Technique (A-FAST) to First- and Second-Year Veterinary Students. AB - Ultrasound techniques, including focused assessment with sonography for trauma (FAST) examinations, are commonly used in veterinary practice, making inclusion of ultrasound in veterinary curricula increasingly important. The best approach for teaching ultrasound techniques in veterinary medicine has not been evaluated. This study compared the results of two training techniques, live-animal training and online video instruction, on students' performance during abdominal FAST (A FAST) examinations. Thirty-eight first- and second-year veterinary students were randomly assigned to learn A-FAST via a live-animal laboratory or an instructional video. The live-animal group received one-on-one instruction in A FAST techniques during a single laboratory. The video group received a link to an instructional video demonstrating A-FAST techniques, allowing unlimited viewing opportunities over a 2-week period. Both groups were also provided written instructional information. All participants were assessed on their ability to find and correctly name the four A-FAST quadrants on a live animal. We found a significant difference between the two groups in the students' ability to identify the diaphragmatic-hepatic (DH) view, but for the other three views (hepatorenal, splenorenal, and cystocolic), training method did not affect performance. Results suggest the potential for using a multi-modal instructional approach to teach ultrasound techniques to veterinary students. PMID- 30285595 TI - Assessing Differences in Understanding of Companion-Animal Preventive Care between a Veterinary Healthcare Team and Pet Owners in a Veterinary Teaching Hospital. AB - Preventive healthcare visits to primary care veterinary practices in the United States have been on the decline over the past decade. One of the main factors that has been identified is a lack of understanding by pet owners regarding the importance of preventive care. The Partners for Healthy Pets Opportunity Survey was adapted for use in this study to determine whether there were differences in perceptions of a veterinary healthcare team between team members and clients, specifically regarding preventive care within the Community Practice service of the Virginia-Maryland College of Veterinary Medicine. Results of this cross sectional study revealed that the clients and veterinary healthcare team tended to be aligned in most areas regarding companion-animal preventive care. There were some specific areas that differed, including a disconnect regarding components of feline wellness visits, reliable sources of medical information, and strength of recommendations from the veterinary healthcare team. The Partners for Healthy Pets Opportunity Survey could be adapted for use in other university based companion-animal general-practice teaching environments to better understand differences between clients and the veterinary healthcare team regarding preventive care and thereby improve educational and service goals of primary care veterinary education. Efforts to better understand and mitigate potential communication gaps between pet owners and veterinary healthcare teams have the potential to improve preventive care not only in university-based practice but also in private clinical practice. PMID- 30285596 TI - Am I Being Understood? Veterinary Students' Perceptions of the Relationship between Their Language Background, Communication Ability, and Clinical Learning. AB - During clinical workplace learning, effective communication between veterinary students and clinical staff is of paramount importance to facilitating learning, assessment, and patient care. Although studies in health sciences education have indicated that students may experience communication difficulties as a result of linguistic, cultural, and other factors and that these difficulties can affect clinical learning and academic outcomes, this has not yet been explored in veterinary clinical educational contexts. In this study, the authors sought to identify whether final-year veterinary students perceived that their communication ability influenced their clinical learning and, if so, whether language background was of significance. Seventy-one students from a final-year cohort at an Australian veterinary school completed a student perception survey at the end of their clinical training. Exploratory factor analysis was used to investigate the extent to which learners perceived that their communication ability influenced their clinical learning. Two factors explained 72.3% of total variance. Factor 1 related to communication ability as a source of concern; Factor 2 related to comprehending and contributing to clinical conversations. Communication ability as a source of concern differed significantly ( p < .001) between students who did and did not have an English-speaking background, but there was no significant difference between these two student groups for Factor 2. Although language background was associated with self-perceived communication ability, evidence also emerged that students may experience communication challenges during clinical learning, irrespective of their language background. PMID- 30285597 TI - Using a Standardized Client Encounter in the Veterinary Curriculum to Practice Veterinarian-Employer Discussions about Animal Cruelty Reporting. AB - Animal cruelty is the antithesis of animal welfare. Because veterinarians take an oath to protect animal welfare, they are professionally obligated to report animal cruelty. Several US states have mandatory reporting laws for veterinarians, and both the American Veterinary Medical Association (AVMA) and the American Animal Hospital Association support reporting. Some state veterinary practice acts, such as Arizona's, also require reporting. Despite this, animal cruelty is not always emphasized in veterinary curricula. As a result, not all veterinary students and graduates feel comfortable recognizing signs of animal cruelty and may not be aware of the resources that are available to them when considering reporting. AVMA suggests that practices develop their own protocols for identifying signs that patients may have been victims of cruelty and consulting on cases with senior colleagues with regard to when to report. To enhance student comfort with these conversations, Midwestern University College of Veterinary Medicine developed a standardized client encounter titled "Grizabella's Final Fight." I hope that other colleges of veterinary medicine will adapt this teaching tool to allow students the opportunity to practice discussions surrounding animal cruelty reporting in the context of state-specific legislation that guides their code of professional conduct. PMID- 30285598 TI - Tracking Veterinary Students' Acquisition of Communication Skills and Clinical Communication Confidence by Comparing Student Performance in the First and Twenty Seventh Standardized Client Encounters. AB - The American Veterinary Medical Association's Council on Education mandates that veterinary students graduate with competence in clinical communication. Communication competence facilitates the successful transition of students into clinical practice by improving veterinary client satisfaction and reducing the risk of litigation. Curricular experimentation with communications training has led to innovative approaches to this content area, including the adoption of standardized patients from human health care education. Although the use of standardized clients (SCs) is time and resource intensive, their use by veterinary educators has allowed students to work through authentic cases in a safe learning environment in which learner goals drive training. Despite the increasing popularity of SC-based communications curricula, outcomes assessment studies that track the resultant student growth are lacking. Ninety students in the inaugural class of 2018 at Midwestern University College of Veterinary Medicine participated in 27 SC encounters over eight consecutive quarters. Students' use of Calgary-Cambridge Guide communication skills was compared in the first and twenty-seventh encounters. On the basis of SC evaluations of student performance, students increased their use of all communication skills in the final encounter compared with baseline. Students were also more likely to take a comprehensive patient history, build rapport, and retain the client. Mean scores for pre- and post-encounter communication confidence, as self-reported by students, also increased. These findings support that an SC-rich curriculum facilitates student acquisition of communication skills and promotes confidence when students approach entry-level clinical tasks such as history taking. PMID- 30285599 TI - Exploring the Social Determinants of Animal Health. AB - An understanding of the One Health and EcoHealth concepts by students is dependent on medical pedagogy and veterinary medical pedagogy having similarities that allow a common discourse. Medical pedagogy includes a focus on the social, political, and economic forces that affect human health, while this discourse is largely absent from veterinary medical pedagogy. There is, however, a gradient in health that human and animal populations experience. This health gradient in human populations, which runs from low to high according to the World Health Organization, is largely explained by "the conditions in which people are born, grow, live, work, and age."1,2 Regarding the human health gradient, other authors have broadened the list of conditions to include access to health care systems used to prevent disease and treat illness, and the distribution of power, money, and resources, which are shaped by social, economic, and political forces.1,2 In human medicine, these conditions are collectively termed the social determinants of health (SDH). Veterinarians who work with the public encounter people and their animals at both the low and the high end of the health gradient. This article explores the concept of the parallel social determinants of animal health (SDAH) using examples within urban, rural, and remote communities in North America as well as abroad. We believe that in order to understand the One Health paradigm it is imperative that veterinary pedagogy include information on, and competence in, SDH and SDAH to ultimately achieve improvements in human, animal, and environmental health and wellbeing. PMID- 30285600 TI - Qualitative pilot study of veterinarians' perceptions of and experiences with counseling about dog walking in companion-animal practice in southern Ontario. AB - Dog wal king is beneficial to dogs and their owners, and it supports One Health, an initiative devoted to improving the health of animals and humans. Despite the benefits of dog walking, many dogs and their owners are not engaging in adequate dog-walking exercise. One way to encourage dog walking is for veterinarians to counsel owners on dog walking during veterinary appointments. This pilot study used individual in-person or telephone interviews to understand veterinarians' perceptions of and experiences with counseling about dog walking in companion animal practice. Seventeen veterinarians licensed to provide canine care in Ontario participated in an interview in 2015. Thematic analysis was used to analyze the interview transcripts. Participants thought dog walking was important for both dogs and owners and discussed physical, social, and mental benefits of dog walking. Participants described barriers to dog-walking counseling including dog owners' lack of compliance or physical condition, dogs' behavior, and lack of time or low priority during appointments. Also, participants discussed how dog walking was not addressed in their professional veterinary education. These findings can be used to educate veterinary students and practicing veterinarians on the value of dog walking for people and dogs and the barriers they may face when counseling clients about dog walking. PMID- 30285601 TI - Do criminal associates impact psychiatric inpatients' social support and interpersonal needs? AB - Suicide risk is elevated among psychiatric inpatients; however, research has not examined moderators of the associations between perceived social support and thwarted belongingness (TB) and perceived burdensomeness (PB), such as involvement with criminal associates. Adult psychiatric inpatients (N = 142) completed assessments. Perceived social support was negatively associated with TB and PB; however, associates' criminal involvement did not moderate these associations. A significant interaction indicated a stronger negative association between perceived social support and TB when participants spent more time with associates. Therefore, time spent with associates, regardless of criminal involvement, may be a relevant interpersonal suicide risk factor. PMID- 30285602 TI - Supporting bereaved students at university: Balancing institutional standards and reputation alongside individual compassion and care. AB - Bereaved university students in the UK are an overlooked population in research, policy, and practice. In this article, we examine the implications of this neglect via (1) international literature on bereavement in young people; (2) international literature on bereavement in higher education students; (3) UK and US literature on workplace bereavement and its implications for universities in preparing the future workforce; and (4) findings from a scoping study of 90 UK universities' bereavement support, which identified no shared comprehensive strategy for student bereavement. Our findings show an urgent need for UK universities to address this neglect. PMID- 30285603 TI - Genome-wide analysis of the rice PPR gene family and their expression profiles under different stress treatments. AB - BACKGROUND: Pentatricopeptide-repeat proteins (PPRs) are characterized by tandem arrays of a degenerate 35-amino-acid (PPR motifs), which can bind RNA strands and participate in post-transcription. PPR proteins family is one of the largest families in land plants and play important roles in organelle RNA metabolism and plant development. However, the functions of PPR genes involved in biotic and abiotic stresses of rice (Oryza sativa L.) remain largely unknown. RESULTS: In the present study, a comprehensive genome-wide analysis of PPR genes was performed. A total of 491 PPR genes were found in the rice genome, of which 246 PPR genes belong to the P subfamily, and 245 genes belong to the PLS subfamily. Gene structure analysis showed that most PPR genes lack intron. Chromosomal location analysis indicated that PPR genes were widely distributed in all 12 rice chromosomes. Phylogenetic relationship analysis revealed the distinct difference between the P and PLS subfamilies. Many PPR proteins are predicted to target chloroplasts or mitochondria, and a PPR protein (LOC_Os10g34310) was verified to localize in mitochondria. Furthermore, three PPR genes (LOC_Os03g17634,LOC_Os07g40820,LOC_Os04g51350) were verified as corresponding miRNA targets. The expression pattern analysis showed that many PPR genes could be induced under biotic and abiotic stresses. Finally, seven PPR genes were confirmed with their expression patterns under salinity or drought stress. CONCLUSIONS: We found 491 PPR genes in the rice genome, and our genes structure analysis and syntenic analysis indicated that PPR genes might be derived from amplification by retro-transposition. The expression pattern present here suggested that PPR proteins have crucial roles in response to different abiotic stresses in rice. Taken together, our study provides a comprehensive analysis of the PPR gene family and will facilitate further studies on their roles in rice growth and development. PMID- 30285604 TI - MITE Tracker: an accurate approach to identify miniature inverted-repeat transposable elements in large genomes. AB - BACKGROUND: Miniature inverted-repeat transposable elements (MITEs) are short, non-autonomous class II transposable elements present in a high number of conserved copies in eukaryote genomes. An accurate identification of these elements can help to shed light on the mechanisms controlling genome evolution and gene regulation. The structure and distribution of these elements are well defined and therefore computational approaches can be used to identify MITEs sequences. RESULTS: Here we describe MITE Tracker, a novel, open source software program that finds and classifies MITEs using an efficient alignment strategy to retrieve nearby inverted-repeat sequences from large genomes. This program groups them into high sequence homology families using a fast clustering algorithm and finally filters only those elements that were likely transposed from different genomic locations because of their low scoring flanking sequence alignment. CONCLUSIONS: Many programs have been proposed to find MITEs hidden in genomes. However, none of them are able to process large-scale genomes such as that of bread wheat. Furthermore, in many cases the existing methods perform high false positive rates (or miss rates). The rice genome was used as reference to compare MITE Tracker against known tools. Our method turned out to be the most reliable in our tests. Indeed, it revealed more known elements, presented the lowest false positive number and was the only program able to run with the bread wheat genome as input. In wheat, MITE Tracker discovered 6013 MITE families and allowed the first structural exploration of MITEs in the complete bread wheat genome. PMID- 30285605 TI - The effects of lncRNA MALAT1 on proliferation, invasion and migration in colorectal cancer through regulating SOX9. AB - BACKGROUND: For the study, we determine the potential biomarkers and uncover the regulatory mechanisms of lncRNA MALAT1 / miR-145 / SOX9 axis on the abilities of cell growth and cell metastasis of colorectal cancer. METHODS: Previously published dataset GSE18105 from GEO database was used for microarray analysis to identify differential-expressed lncRNAs and mRNAs. The miRNA which had targeted relationships with both lncRNA and mRNA was predicted using miRCode and Targetscan. The association between lncRNA and miRNA, miRNA and mRNA was verified using dual-luciferase reporter assay. Expression levels of lncRNA MALAT1, miR-145 and SOX9 were examined by quantitative RT-PCR analysis. The cell viability of two cancer cell lines was compared by CCK-8 assay. Colony formation was hired to detected cell proliferation. The cell cycle distribution and apoptotic cell rate were conducted by flow cytometry assay. Wound healing as well as transwell assay were compare the cell migration and cell invasion respectively among groups. The effect of MALAT1 on colorectal cancer in vivo was constructed by xenograft model. RESULTS: Significantly dysregulated lncRNAs and mRNAs were identified by microarray analysis. By experimental verification, MALAT1 and SOX9 were expressed in a high percentage of colorectal cancer tumors and cells, while miR-145 was in a low expression. We also identified miR-145 as a target of MALAT1 and SOX9. MALAT1 played a role in regulating cancer process by functioning as a competing endogenous RNA. Silencing MALAT1 could effectively decrease the expression level of SOX9, thus suppress cell viability and metastasis. Down-regulated MALAT1 could induce resistance of G1 phase in cell cycle, and facilitation of colorectal cancer cell apoptosis. Nude mice injected with cells transfected with si-MALAT1 had smaller tumor on size and weight. CONCLUSIONS: The regulatory function of lncRNA MALAT1 / miR-145 / SOX9 axis was revealed in colorectal cancer based on bioinformatics analysis. LncRNA MALAT1 could facilitate colorectal cancer cell proliferation, invasion and migration by down-regulating miR-145 and up regulating SOX9. LncRNA MALAT1 could suppress cell cycle and apoptosis through MALAT1 / miR-145 / SOX9 axis. PMID- 30285606 TI - Uncovering new disease indications for G-protein coupled receptors and their endogenous ligands. AB - BACKGROUND: The Open Targets Platform integrates different data sources in order to facilitate identification of potential therapeutic drug targets to treat human diseases. It currently provides evidence for nearly 2.6 million potential target disease pairs. G-protein coupled receptors are a drug target class of high interest because of the number of successful drugs being developed against them over many years. Here we describe a systematic approach utilizing the Open Targets Platform data to uncover and prioritize potential new disease indications for the G-protein coupled receptors and their ligands. RESULTS: Utilizing the data available in the Open Targets platform, potential G-protein coupled receptor and endogenous ligand disease association pairs were systematically identified. Intriguing examples such as GPR35 for inflammatory bowel disease and CXCR4 for viral infection are used as illustrations of how a systematic approach can aid in the prioritization of interesting drug discovery hypotheses. Combining evidences for G-protein coupled receptors and their corresponding endogenous peptidergic ligands increases confidence and provides supportive evidence for potential new target-disease hypotheses. Comparing such hypotheses to the global pharma drug discovery pipeline to validate the approach showed that more than 93% of G protein coupled receptor-disease pairs with a high overall Open Targets score involved receptors with an existing drug discovery program. CONCLUSIONS: The Open Targets gene-disease score can be used to prioritize potential G-protein coupled receptors-indication hypotheses. In addition, availability of multiple different evidence types markedly increases confidence as does combining evidence from known receptor-ligand pairs. Comparing the top-ranked hypotheses to the current global pharma pipeline serves validation of our approach and identifies and prioritizes new therapeutic opportunities. PMID- 30285608 TI - A deep learning-based algorithm for 2-D cell segmentation in microscopy images. AB - BACKGROUND: Automatic and reliable characterization of cells in cell cultures is key to several applications such as cancer research and drug discovery. Given the recent advances in light microscopy and the need for accurate and high-throughput analysis of cells, automated algorithms have been developed for segmenting and analyzing the cells in microscopy images. Nevertheless, accurate, generic and robust whole-cell segmentation is still a persisting need to precisely quantify its morphological properties, phenotypes and sub-cellular dynamics. RESULTS: We present a single-channel whole cell segmentation algorithm. We use markers that stain the whole cell, but with less staining in the nucleus, and without using a separate nuclear stain. We show the utility of our approach in microscopy images of cell cultures in a wide variety of conditions. Our algorithm uses a deep learning approach to learn and predict locations of the cells and their nuclei, and combines that with thresholding and watershed-based segmentation. We trained and validated our approach using different sets of images, containing cells stained with various markers and imaged at different magnifications. Our approach achieved a 86% similarity to ground truth segmentation when identifying and separating cells. CONCLUSIONS: The proposed algorithm is able to automatically segment cells from single channel images using a variety of markers and magnifications. PMID- 30285607 TI - Comparative analysis of cytokinin response factors in Brassica diploids and amphidiploids and insights into the evolution of Brassica species. AB - BACKGROUND: Cytokinin is a classical phytohormone that plays important roles in numerous plant growth and development processes. In plants, cytokinin signals are transduced by a two-component system, which involves many genes, including cytokinin response factors (CRFs). Although CRFs take vital part in the growth of Arabidopsis thaliana and Solanum lycopersicum, little information of the CRFs in the Brassica U-triangle species has been known yet. RESULTS: We identified and compared 141 CRFs in the diploids and amphidiploids of Brassica species, including B. rapa, B. oleracea, B. nigra, B. napus, and B. juncea. For all the 141 CRFs, the sequence and structure analysis, physiological and biochemical characteristics analysis were performed. Meanwhile, the Ka/Ks ratios of orthologous and paralogous gene pairs were calculated, which indicated the natural selective pressure upon the overall length or a certain part of the CRFs. The expression profiles of CRFs in different tissues and under various stresses were analyzed in B. oleracea, B. nigra, and B. napus. The similarities and differences in gene sequences and expression profiles among the homologous genes of these species were discussed. In addition, AtCRF11 and its ortholog BrCRF11a were identified to be related to primary root growth in Arabidopsis. CONCLUSION: This study performed a genome-wide comparative analysis of the CRFs in the diploids and amphidiploids of the Brassica U-triangle species. Many similarities and differences in gene sequences and expression profiles existed among the CRF homologous genes of these species. In the bioinformatics analysis, we found the close relativity of the CRF homologous genes in the Brassica A and C genomes and the distinctiveness of those in the B genome, and the CRF homologous genes in B subgenome were considerably influenced by the A subgenome of B. juncea. In addition, we identified a new function of the Clade V CRFs related to root growth, which also clarified the functional conservation between Arabidopsis and B. rapa. These results not only offer useful information on the functional analysis of CRFs but also provide new insights into the evolution of Brassica species. PMID- 30285609 TI - Effect of pulsed transcranial ultrasound stimulation at different number of tone burst on cortico-muscular coupling. AB - BACKGROUND: Pulsed transcranial ultrasound stimulation (pTUS) can modulate the neuronal activity of motor cortex and elicit muscle contractions. Cortico muscular coupling (CMC) can serve as a tool to identify interaction between the oscillatory activity of the motor cortex and effector muscle. This research aims to explore the neuromodulatory effect of low-intensity, pTUS with different number of tone burst to neural circuit of motor-control system by analyzing the coupling relationship between motor cortex and tail muscle in mouse. The motor cortex of mice was stimulated by pulsed transcranial ultrasound with different number of tone bursts (NTB = 100 150 200 250 300). The local field potentials (LFPs) in tail motor cortex and electromyography (EMG) in tail muscles were recorded simultaneously during pTUS. The change of integral coupling strength between cortex and muscle was evaluated by mutual information (MI). The directional information interaction between them were analyzed by transfer entropy (TE). RESULTS: Almost all of the MI and TE values were significantly increased by pTUS. The results of MI showed that the CMC was significantly enhanced with the increase of NTB. The TE results showed the coupling strength of CMC in descending direction (from LFPs to EMG) was significantly higher than that in ascending direction (from EMG to LFPs) after stimulation. Furthermore, compared to NTB = 100, the CMC in ascending direction were significantly enhanced when NTB = 250, 300, and CMC in descending direction were significantly enhanced when NTB = 200, 250, 300. CONCLUSION: These results confirm that the CMC between motor cortex and the tail muscles in mouse could be altered by pTUS. And by increasing the NTB (i.e. sonication duration), the coupling strength within the cortico-muscular circuit could be increased, which might further influence the motor function of mice. It demonstrates that, using MI and TE method, the CMC could be used for quantitatively evaluating the effect of pTUS with different NTBs, which might provide a new insight into the effect of pTUS neuromodulation in motor cortex. PMID- 30285610 TI - High-throughput proteomic profiling of the fish liver following bacterial infection. AB - BACKGROUND: High-throughput proteomics was used to determine the role of the fish liver in defense responses to bacterial infection. This was done using a rainbow trout (Oncorhynchus mykiss) model following infection with Aeromonas salmonicida, the causative agent of furunculosis. The vertebrate liver has multifaceted functions in innate immunity, metabolism, and growth; we hypothesize this tissue serves a dual role in supporting host defense in parallel to metabolic adjustments that promote effective immune function. While past studies have reported mRNA responses to A. salmonicida in salmonids, the impact of bacterial infection on the liver proteome remains uncharacterized in fish. RESULTS: Rainbow trout were injected with A. salmonicida or PBS (control) and liver extracted 48 h later for analysis on a hybrid quadrupole-Orbitrap mass spectrometer. A label free method was used for protein abundance profiling, which revealed a strong innate immune response along with evidence to support parallel rewiring of metabolic and growth systems. 3076 proteins were initially identified against all proteins (n = 71,293 RefSeq proteins) annotated in a single high-quality rainbow trout reference genome, of which 2433 were maintained for analysis post-quality filtering. Among the 2433 proteins, 109 showed significant differential abundance following A. salmonicida challenge, including many upregulated complement system and acute phase response proteins, in addition to molecules with putative functions that may support metabolic re-adjustments. We also identified novel expansions in the complement system due to gene and whole genome duplication events in salmonid evolutionary history, including eight C3 proteins showing differential changes in abundance. CONCLUSIONS: This study provides the first high-throughput proteomic examination of the fish liver in response to bacterial challenge, revealing novel markers for the host defense response, and evidence of metabolic remodeling in conjunction with activation of innate immunity. PMID- 30285611 TI - Genome-wide survey of potato MADS-box genes reveals that StMADS1 and StMADS13 are putative downstream targets of tuberigen StSP6A. AB - BACKGROUND: MADS-box genes encode transcription factors that are known to be involved in several aspects of plant growth and development, especially in floral organ specification. To date, the comprehensive analysis of potato MADS-box gene family is still lacking after the completion of potato genome sequencing. A genome-wide characterization, classification, and expression analysis of MADS-box transcription factor gene family was performed in this study. RESULTS: A total of 153 MADS-box genes were identified and categorized into MIKC subfamily (MIKCC and MIKC*) and M-type subfamily (Malpha, Mbeta, and Mgamma) based on their phylogenetic relationships to the Arabidopsis and rice MADS-box genes. The potato M-type subfamily had 114 members, which is almost three times of the MIKC members (39), indicating that M-type MADS-box genes have a higher duplication rate and/or a lower loss rate during potato genome evolution. Potato MADS-box genes were present on all 12 potato chromosomes with substantial clustering that mainly contributed by the M-type members. Chromosomal localization of potato MADS-box genes revealed that MADS-box genes, mostly MIKC, were located on the duplicated segments of the potato genome whereas tandem duplications mainly contributed to the M-type gene expansion. The potato MIKC subfamily could be further classified into 11 subgroups and the TT16-like, AGL17-like, and FLC-like subgroups found in Arabidopsis were absent in potato. Moreover, the expressions of potato MADS-box genes in various tissues were analyzed by using RNA-seq data and verified by quantitative real-time PCR, revealing that the MIKCC genes were mainly expressed in flower organs and several of them were highly expressed in stolon and tubers. StMADS1 and StMADS13 were up-regulated in the StSP6A-overexpression plants and down-regulated in the StSP6A-RNAi plant, and their expression in leaves and/or young tubers were associated with high level expression of StSP6A. CONCLUSION: Our study identifies the family members of potato MADS-box genes and investigate the evolution history and functional divergence of MADS-box gene family. Moreover, we analyze the MIKCC expression patterns and screen for genes involved in tuberization. Finally, the StMADS1 and StMADS13 are most likely to be downstream target of StSP6A and involved in tuber development. PMID- 30285613 TI - Investigating the frequency of triploid Atlantic salmon in wild Norwegian and Russian populations. AB - BACKGROUND: Fish may display variations in ploidy, including three sets of chromosomes, known as triploidy. A recent study revealed a frequency of ~ 2% spontaneous (i.e., non-intentional) triploidy in domesticated Atlantic salmon produced in Norwegian aquaculture in the period 2007-2014. In contrast, the frequency of triploidy in wild salmon populations has not been studied thus far, and in wild populations of other organisms, it has been very rarely studied. In population genetic data sets, individuals that potentially display chromosome abnormalities, such as triploids with three alleles, are typically excluded on the premise that they may reflect polluted or otherwise compromised samples. Here, we critically re-investigated the microsatellite genetic profile of ~ 6000 wild Atlantic salmon sampled from 80 rivers in Norway and Russia, to investigate the frequency of triploid individuals in wild salmon populations for the first time. RESULTS: We detected a single triploid salmon, and five individuals displaying three alleles at one of the loci, thus regarded as putatively trisomic. This gave an overall frequency of triploid and putatively trisomic individuals in the data set of 0.017 and 0.083% respectively. The triploid salmon was an adult female, and had spent 2 years in freshwater and 2 years in the sea. CONCLUSIONS: We conclude that the frequency of naturally-occurring triploid Atlantic salmon in wild Norwegian and Russian populations is very low, and many fold lower than the frequency of spontaneous triploids observed in aquaculture. Our results suggest that aquaculture rearing conditions substantially increase the probability of triploidy to develop, and/or permits greater survival of triploid individuals, in comparison to the wild. PMID- 30285612 TI - Environmental pH modulates transcriptomic responses in the fungus Fusarium sp. associated with KSHB Euwallacea sp. near fornicatus. AB - BACKGROUND: The Ambrosia Fusarium Clade phytopathogenic Fusarium fungi species have a symbiotic relationship with ambrosia beetles in the genus Euwallacea (Coleoptera: Curculionidae). Related beetle species referred to as Euwallacea sp. near fornicatus have been spread in California, USA and are recognized as the causal agents of Fusarium dieback, a disease that causes mortality of many plant species. Despite the importance of this fungi, no transcriptomic resources have been generated. The datasets described here represent the first ever transcripts available for these species. We focused our study on the isolated species of Fusarium that is associated with one of the cryptic species referred to as Kuroshio Shot Hole Borer (KSHB) Euwallacea sp. near fornicatus. RESULTS: Hydrogen concentration is a critical signal in fungi for growth and host colonization, the aim of this study was to evaluate the effect of different pH conditions on growth and gene expression of the fungus Fusarium sp. associated with KSHB. An RNA-seq approach was used to compare the gene expression of the fungus grown for 2 weeks in liquid medium at three different pH levels (5.0, 6.0, and 7.0). An unbuffered treatment was included to evaluate the capability of the fungus to change the pH of its environment and the impact in gene expression. The results showed that the fungus can grow and modulate its genetic expression at different pH conditions; however, growth was stunted in acidic pH in comparison with neutral pH. The results showed a differential expression pattern in each pH condition even when acidic conditions prevailed at the end of the experiment. After comparing transcriptomics data from the three treatments, we found a total of 4,943 unique transcripts that were differentially expressed. CONCLUSIONS: We identified transcripts related to pH signaling such as the conserved PAL/RIM pathway, some transcripts related to secondary metabolism and other transcripts that were differentially expressed. Our analysis suggests possible mechanisms involved in pathogenicity in this novel Fusarium species. This is the first report that shows transcriptomic data of this pathogen as well as the first report of genes and proteins involved in their metabolism identifying potential virulence factors.

PMID- 30285615 TI - Transcriptome sequencing of Pinus kesiya var. langbianensis and comparative analysis in the Pinus phylogeny. AB - BACKGROUND: Pines are widely distributed in the Northern Hemisphere and have a long evolutionary history. The availability of transcriptome data has facilitated comparative transcriptomics for studying the evolutionary patterns associated with the different geographical distributions of species in the Pinus phylogeny. RESULTS: The transcriptome of Pinus kesiya var. langbianensis was sequenced using the Illumina HiSeq 2000 platform, and a total of 68,881 unigenes were assembled by Trinity. Transcriptome sequences of another 12 conifer species were downloaded from public databases. All of the pairwise orthologues were identified by comparative transcriptome analysis in 13 conifer species, from which the rate of diversification was calculated and a phylogenetic tree inferred. All of the fast evolving positive selection sequences were identified, and some salt-, drought-, and abscisic acid-resistance genes were discovered. CONCLUSIONS: mRNA sequences of P. kesiya var. langbianensis were obtained by transcriptome sequencing, and a large number of simple sequence repeat and short nucleotide polymorphism loci were detected. These data can be used in molecular marker-assisted selected in pine breeding. Divergence times were estimated in the 13 conifer species using comparative transcriptomic analysis. A number of positive selection genes were found to be related to environmental factors. Salt- and abscisic acid-related genes exhibited different selection patterns between coastal and inland Pinus. Our findings help elucidate speciation patterns in the Pinus lineage. PMID- 30285614 TI - Genome wide identification and predicted functional analyses of NAC transcription factors in Asian pears. AB - BACKGROUND: NAC proteins contribute to diverse plant developmental processes as well as tolerances to biotic and abiotic stresses. The pear genome had been decoded and provided the basis for the genome-wide analysis to find the evolution, duplication, gene structures and predicted functions of PpNAC transcription factors. RESULTS: A total of 185 PpNAC genes were found in pear, of which 148 were mapped on chromosomes while 37 were on unanchored scaffolds. Phylogeny split the NAC genes into 6 clades (Group1- Group6) with their sub clades (~ subgroup A to subgroup H) and each group displayed common motifs with no/minor change. The numbers of exons in each group varied from 1 to 12 with an average of 3 while 44 pairs from all groups showed their duplication events. qPCR and RNA-Seq data analyses in different pear cultivars/species revealed some predicted functions of PpNAC genes i.e. PpNACs 37, 61, 70 (2A), 53, 151(2D), 10, 92, 130 and 154 (3D) were potentially involved in bud endodormancy, PpNACs 61, 70 (2A), 172, 176 and 23 (4E) were associated with fruit pigmentations in blue light, PpNACs 127 (1E), 46 (1G) and 56 (5A) might be related to early, middle and late fruit developments respectively. Besides, all genes from subgroups 2D and 3D were found to be related with abiotic stress (cold, salt and drought) tolerances by targeting the stress responsive genes in pear. CONCLUSIONS: The present genome wide analysis provided valuable information for understanding the classification, motif and gene structure, evolution and predicted functions of NAC gene family in pear as well as in higher plants. NAC TFs play diverse and multifunctional roles in biotic and abiotic stresses, growth and development and fruit ripening and pigmentation through multiple pathways in pear. PMID- 30285617 TI - Combining controls can improve power in two-stage association studies. AB - BACKGROUND: High dimensional case control studies are ubiquitous in the biological sciences, particularly genomics. To maximise power while constraining cost and to minimise type-1 error rates, researchers typically seek to replicate findings in a second experiment on independent cohorts before proceeding with further analyses. This can be an expensive procedure, particularly when control samples are difficult to recruit or ascertain; for example in inter-disease comparisons, or studies on degenerative diseases. RESULTS: This paper presents a method in which control (or case) samples from the discovery cohort are re-used in a replication study. The theoretical implications of this method are discussed and simulated genome-wide association study (GWAS) tests are used to compare performance against the standard approach in a range of circumstances. Using similar methods, a procedure is proposed for 'partial replication' using a new independent cohort consisting of only controls. This methods can be used to provide some validation of findings when a full replication procedure is not possible. The new method has differing sensitivity to confounding in study cohorts compared to the standard procedure, which must be considered in its application. Type-1 error rates in these scenarios are analytically and empirically derived, and an online tool for comparing power and error rates is provided. CONCLUSIONS: In several common study designs, a shared-control method allows a substantial improvement in power while retaining type-1 error rate control. Although careful consideration must be made of all necessary assumptions, this method can enable more efficient use of data in GWAS and other applications. PMID- 30285618 TI - A Lotus japonicus E3 ligase interacts with the Nod Factor Receptor 5 and positively regulates nodulation. AB - BACKGROUND: Post-translational modification of receptor proteins is involved in activation and de-activation of signalling systems in plants. Both ubiquitination and deubiquitination have been implicated in plant interactions with pathogens and symbionts. RESULTS: Here we present LjPUB13, a PUB-ARMADILLO repeat E3 ligase that specifically ubiquitinates the kinase domain of the Nod Factor receptor NFR5 and has a direct role in nodule organogenesis events in Lotus japonicus. Phenotypic analyses of three LORE1 retroelement insertion plant lines revealed that pub13 plants display delayed and reduced nodulation capacity and retarded growth. LjPUB13 expression is spatially regulated during symbiosis with Mesorhizobium loti, with increased levels in young developing nodules. CONCLUSION: LjPUB13 is an E3 ligase with a positive regulatory role during the initial stages of nodulation in L. japonicus. PMID- 30285619 TI - Integration of small RNAs and transcriptome sequencing uncovers a complex regulatory network during vernalization and heading stages of orchardgrass (Dactylis glomerata L.). AB - BACKGROUND: Flowering is a critical reproductive process in higher plants. Timing of optimal flowering depends upon the coordination among seasonal environmental cues. For cool season grasses, such as Dactylis glomerata, vernalization induced by low temperature provides competence to initiate flowering after prolonged cold. We combined analyses of the transcriptome and microRNAs (miRNAs) to generate a comprehensive resource for regulatory miRNAs and their target circuits during vernalization and heading stages. RESULTS: A total of 3,846 differentially expressed genes (DEGs) and 69 differentially expressed miRNAs were identified across five flowering stages. The expression of miR395, miR530, miR167, miR396, miR528, novel_42, novel_72, novel_107, and novel_123 demonstrated significant variations during vernalization. These miRNA targeted genes were involved in phytohormones, transmembrane transport, and plant morphogenesis in response to vernalization. The expression patterns of DEGs related to plant hormones, stress responses, energy metabolism, and signal transduction changed significantly in the transition from vegetative to reproductive phases. CONCLUSIONS: Five hub genes, c136110_g1 (BRI1), c131375_g1 (BZR1), c133350_g1 (VRN1), c139830_g1 (VIN3), and c125792_g2 (FT), might play central roles in vernalization response. Our comprehensive analyses have provided a useful platform for investigating consecutive transcriptional and post-transcriptional regulation of critical phases in D. glomerata and provided insights into the genetic engineering of flowering-control in cereal crops. PMID- 30285620 TI - Exclusivity offers a sound yet practical species criterion for bacteria despite abundant gene flow. AB - BACKGROUND: The question of whether bacterial species objectively exist has long divided microbiologists. A major source of contention stems from the fact that bacteria regularly engage in horizontal gene transfer (HGT), making it difficult to ascertain relatedness and draw boundaries between taxa. A natural way to define taxa is based on exclusivity of relatedness, which applies when members of a taxon are more closely related to each other than they are to any outsider. It is largely unknown whether exclusive bacterial taxa exist when averaging over the genome or are rare due to rampant hybridization. RESULTS: Here, we analyze a collection of 701 genomes representing a wide variety of environmental isolates from the family Streptomycetaceae, whose members are competent at HGT. We find that the presence/absence of auxiliary genes in the pan-genome displays a hierarchical (tree-like) structure that correlates significantly with the genealogy of the core-genome. Moreover, we identified the existence of many exclusive taxa, although individual genes often contradict these taxa. These conclusions were supported by repeating the analysis on 1,586 genomes belonging to the genus Bacillus. However, despite confirming the existence of exclusive groups (taxa), we were unable to identify an objective threshold at which to assign the rank of species. CONCLUSIONS: The existence of bacterial taxa is justified by considering average relatedness across the entire genome, as captured by exclusivity, but is rejected if one requires unanimous agreement of all parts of the genome. We propose using exclusivity to delimit taxa and conventional genome similarity thresholds to assign bacterial taxa to the species rank. This approach recognizes species that are phylogenetically meaningful, while also establishing some degree of comparability across species-ranked taxa in different bacterial clades. PMID- 30285621 TI - Bead-linked transposomes enable a normalization-free workflow for NGS library preparation. AB - BACKGROUND: Transposome-based technologies have enabled the streamlined production of sequencer-ready DNA libraries; however, current methods are highly sensitive to the amount and quality of input nucleic acid. RESULTS: We describe a new library preparation technology (Nextera DNA Flex) that utilizes a known concentration of transposomes conjugated directly to beads to bind a fixed amount of DNA, and enables direct input of blood and saliva using an integrated extraction protocol. We further report results from libraries generated outside the standard parameters of the workflow, highlighting novel applications for Nextera DNA Flex, including human genome builds and variant calling from below 1 ng DNA input, customization of insert size, and preparation of libraries from short fragments and severely degraded FFPE samples. Using this bead-linked library preparation method, library yield saturation was observed at an input amount of 100 ng. Preparation of libraries from a range of species with varying GC levels demonstrated uniform coverage of small genomes. For large and complex genomes, coverage across the genome, including difficult regions, was improved compared with other library preparation methods. Libraries were successfully generated from amplicons of varying sizes (from 50 bp to 11 kb), however, a decrease in efficiency was observed for amplicons smaller than 250 bp. This library preparation method was also compatible with poor-quality DNA samples, with sequenceable libraries prepared from formalin-fixed paraffin-embedded samples with varying levels of degradation. CONCLUSIONS: In contrast to solution based library preparation, this bead-based technology produces a normalized, sequencing-ready library for a wide range of DNA input types and amounts, largely obviating the need for DNA quantitation. The robustness of this bead-based library preparation kit and flexibility of input DNA facilitates application across a wide range of fields. PMID- 30285622 TI - The rare orange-red colored Euphorbia pulcherrima cultivar 'Harvest Orange' shows a nonsense mutation in a flavonoid 3'-hydroxylase allele expressed in the bracts. AB - BACKGROUND: Commercially available poinsettia (Euphorbia pulcherrima) varieties prevalently accumulate cyanidin derivatives and show intense red coloration. Orange-red bract color is less common. We investigated four cultivars displaying four different red hues with respect to selected enzymes and genes of the anthocyanin pathway, putatively determining the color hue. RESULTS: Red hues correlated with anthocyanin composition and concentration and showed common dark red coloration in cultivars 'Christmas Beauty' and 'Christmas Feeling' where cyanidin derivatives were prevalent. In contrast, orange-red bract color is based on the prevalent presence of pelargonidin derivatives that comprised 85% of the total anthocyanin content in cv. 'Premium Red' and 96% in cv. 'Harvest Orange' (synonym: 'Orange Spice'). cDNA clones of flavonoid 3'-hydroxylase (F3'H) and dihydroflavonol 4-reductase (DFR) were isolated from the four varieties, and functional activity and substrate specificity of the corresponding recombinant enzymes were studied. Kinetic studies demonstrated that poinsettia DFRs prefer dihydromyricetin and dihydroquercetin over dihydrokaempferol, and thus, favor the formation of cyanidin over pelargonidin. Whereas the F3'H cDNA clones of cultivars 'Christmas Beauty', 'Christmas Feeling', and 'Premium Red' encoded functionally active enzymes, the F3'H cDNA clone of cv. 'Harvest Orange' contained an insertion of 28 bases, which is partly a duplication of 20 bases found close to the insertion site. This causes a frameshift mutation with a premature stop codon after nucleotide 132 and, therefore, a non-functional enzyme. Heterozygosity of the F3'H was demonstrated in this cultivar, but only the mutated allele was expressed in the bracts. No correlation between F3'H expression and the color hue could be observed in the four species. CONCLUSIONS: Rare orange-red poinsettia hues caused by pelargonidin based anthocyanins can be achieved by different mechanisms. F3'H is a critical step in the establishment of orange red poinsettia color. Although poinsettia DFR shows a low substrate specificity for dihydrokaempferol, sufficient precursor for pelargonidin formation is available in planta, in the absence of F3'H activity. PMID- 30285623 TI - Skin cancer risk perception and sun protection behavior at work, at leisure, and on sun holidays: a survey for Danish outdoor and indoor workers. AB - BACKGROUND: To prevent occupational skin cancer, it is essential that the sun protective behavior of outdoor workers is adequate. The aim is to study the sun protective behavior of Danish outdoor workers at work, at leisure, and on sun holiday and compare it to that of indoor workers. METHODS: This is a cross sectional study, based on a 53-item survey completed by Danish outdoor (n = 380) and indoor workers (n = 119) in 2016-2017. Status as outdoor or indoor worker was decided based on self-report and behavioral differences were tested using (paired) t tests and multiple regression adjusted for age, sex, educational level, history of smoking, and skin type. RESULTS: Danish outdoor workers at work use sun protection less than they do at leisure and on sun holiday (alpha < .05) where their sun protection behavior is similar to that of indoor workers. The proportion of Danish outdoor workers that always/often use sun protection at work is for shade seeking around noon 4.2%, sunscreen 34.5%, wide-brimmed hat 25.3%, and long trousers and shirt with sleeves 42.4%. Of Danish outdoor workers, 49.5% do not think about the risk of occupational skin cancer and 11.8% think the risk is insignificant, 32.4% think that the use of sun protection is of low or no importance, 84.2% consider sunburn important as skin cancer risk factor still 88.9% have a history of sunburn at work, > 80.0% agree that risk of skin cancer is reduced by the use of sun protection, and only 4.0% dismiss the possibility of sun protection use at work. CONCLUSIONS: Skin cancer risk and use of sun protection at work are largely neglected in Danish outdoor workers, more so than at leisure and on sun holiday where their risk behavior resembles that of indoor workers. This indicates an untapped workplace preventive potential. PMID- 30285624 TI - Efficient generation of stable, heritable gene edits in wheat using CRISPR/Cas9. AB - BACKGROUND: The use of CRISPR/Cas9 systems could prove to be a valuable tool in crop research, providing the ability to fully knockout gene function in complex genomes or to precisely adjust gene function by knockout of individual alleles. RESULTS: We compare gene editing in hexaploid wheat (Triticum aestivum) with diploid barley (Hordeum vulgare), using a combination of single genome and tri genome targeting. High efficiency gene editing, 11-17% for single genome targeted guides and 5% for tri-genome targeted guides, was achieved in wheat using stable Agrobacterium-mediated transformation. Gene editing in wheat was shown to be predominantly heterozygous, edits were inherited in a Mendelian fashion over multiple generations and no off-target effects were observed. Comparison of editing between the two species demonstrated that more stable, heritable edits were produced in wheat, whilst barley exhibited continued and somatic editing. CONCLUSION: Our work shows the potential to obtain stable edited transgene-free wheat lines in 36 weeks through only two generations and that targeted mutagenesis of individual homeologues within the wheat genome is achievable with a modest amount of effort, and without off-target mutations or the need for lengthy crossing strategies. PMID- 30285625 TI - Air and waterborne microbiome of a pharmaceutical plant provide insights on spatiotemporal variations and community resilience after disturbance. AB - BACKGROUND: The presence of microrganisms in pharmaceutical production plant environments is typically monitored by cultural methods, however these cannot detect the unculturable fraction of the microbial community. To get more accurate information on the composition of these indoor microbial communities, both water and air microbiome from a pharmaceutical production plant were profiled by 16S amplicon sequencing. RESULTS: In the water system, we found taxa which typically characterize surface freshwater, groundwater and oligotrophic environments. The airborne microbiome resulted dominated by taxa usually found in outdoor air in combination with human-associated taxa. The alpha- and beta- diversity values showed that the heat-based sanitization process of the water plant affects the composition of the water microbiome by transiently increasing both diversity and evenness. Taxonomic compositional shifts were also detected in response to sanitization, consisting in an increase of Firmicutes and alpha-Proteobacteria. On the other hand, seasonality seems to be the main driver of bacterial community composition in air of this work environment. CONCLUSIONS: This approach resulted useful to describe the taxonomy of these indoor microbiomes and could be further applied to other built environments, in which the knowledge of the microbiome composition is of relevance. In addition, this study could assist in the design of new guidelines to improve microbiological quality control in indoor work environments. PMID- 30285626 TI - Environmentally-driven gene content convergence and the Bacillus phylogeny. AB - BACKGROUND: Members of the Bacillus genus have been isolated from a variety of environments. However, the relationship between potential metabolism and the niche from which bacteria of this genus have been isolated has not been extensively studied. The existence of a monophyletic aquatic Bacillus group, composed of members isolated from both marine and fresh water has been proposed. Here, we present a phylogenetic/phylogenomic analysis to investigate the potential relationship between the environment from which group members have been isolated and their evolutionary origin. We also carried out hierarchical clustering based on functional content to test for potential environmental effects on the genetic content of these bacteria. RESULTS: The phylogenetic reconstruction showed that Bacillus strains classified as aquatic have evolutionary origins in different lineages. Although we observed the presence of a clade consisting exclusively of aquatic Bacillus, it is not comprised of the same strains previously reported. In contrast to phylogeny, clustering based on the functional categories of the encoded proteomes resulted in groups more compatible with the environments from which the organisms were isolated. This evidence suggests a detectable environmental influence on bacterial genetic content, despite their different evolutionary origins. CONCLUSION: Our results suggest that aquatic Bacillus species have polyphyletic origins, but exhibit convergence at the gene content level. PMID- 30285627 TI - Non-invasive cardiac output measurement with electrical velocimetry in patients undergoing liver transplantation: comparison of an invasive method with pulmonary thermodilution. AB - BACKGROUND: The goal of this study was to evaluate the accuracy and interchangeability between continuous cardiac output (CO) measured by electrical velocimetry (COEv) and continuous cardiac output obtained using the pulmonary thermodilution method (COPAC) during living donor liver transplantation (LDLT). METHOD: Twenty-three patients were enrolled in this prospective observational study. CO was recorded by both two methods and compared at nine specific time points. The data were analyzed using correlation coefficients, Bland-Altman analysis for the percentage errors, and the concordance rate for trend analysis using a four-quadrant plot. RESULTS: In total, 207 paired datasets were recorded during LDLT. CO data were in the range of 2.8-12.7 L/min measured by PAC and 3.4 14.9 L/min derived from the EV machine. The correction coefficient between COPAC and COEv was 0.415 with p < 0.01. The 95% limitation agreement was - 5.9 to 3.4 L/min and the percentage error was 60%. The concordance rate was 56.5%. CONCLUSIONS: The AesculonTM monitor is not yet interchangeable with continuous thermodilution CO monitoring during LDLT. TRIAL REGISTRATION: The study was approved by the Institutional Review Board of Chang Gung Medical Foundation in Taiwan (registration number: 201600264B0 ). PMID- 30285628 TI - Transcriptomic response to parasite infection in Nile tilapia (Oreochromis niloticus) depends on rearing density. AB - BACKGROUND: Captive animal populations, be it for food production or conservation programmes, are often maintained at densities far beyond those in natural environments, which can have profound effects on behaviour, immune and stress levels, and ultimately welfare. How such alterations impact transcriptional responses to pathogen infection is a 'different kettle of fish' and remains poorly understood. Here, we assessed survival and gene expression profiles of infected fish reared at two different densities to elucidate potential functional genomic mechanisms for density-related differences in disease susceptibility. RESULTS: Utilising a whole-transcriptome sequencing (RNAseq) approach, we demonstrate that rearing density in tilapia (Oreochromis niloticus) significantly impacts susceptibility to the oomycete Saprolegnia parasitica, via altered transcriptional infection responses. Tilapia held at low densities have increased expression of genes related to stress, likely due to increased aggressive interactions. When challenged with Saprolegnia, low-density fish exhibit altered expression of inflammatory gene responses and enhanced levels of adaptive immune gene suppression compared to fish reared at higher density, resulting in significantly increased mortality rates. In addition, Saprolegnia infection substantially perturbs expression of circadian clock genes, with fish reared at low-density having higher levels of molecular clock dysregulation. CONCLUSIONS: Our results reveal the wide-scale impact of stocking density on transcriptional responses to infection and highlight the need to incorporate circadian biology into our understanding of disease dynamics in managed animals. PMID- 30285629 TI - Derivation of the economic value of R0 for macroparasitic diseases and application to sea lice in salmon. AB - BACKGROUND: Macroparasites, such as ticks, lice, and helminths, are a concern in livestock and aquaculture production, and can be controlled by genetic improvement of the host population. Genetic improvement should aim at reducing the rate at which parasites spread across the farmed population. This rate is determined by the basic reproduction ratio, i.e. [Formula: see text], which is the appropriate breeding goal trait. This study aims at providing a method to derive the economic value of [Formula: see text]. METHODS: Costs of a disease are the sum of production losses and expenditures on disease control. Genetic improvement of [Formula: see text] lowers the loss-expenditure frontier. Its economic effect depends on whether the management strategy is optimized or not. The economic value may be derived either from the reduction in losses with constant expenditures or from the reduction in expenditures with constant losses. RESULTS: When [Formula: see text] <= 1, the economic value of a further reduction is zero because there is no risk of a major epidemic. When [Formula: see text] > 1 and management is optimized, the economic value increases with decreasing values of [Formula: see text], because both the mean number of parasites per host and frequency of treatments decrease at an increasing rate when [Formula: see text] decreases. When [Formula: see text] > 1 and management is not optimized, the economic value depends on whether genetic improvement is used for reducing expenditures or losses. For sea lice in salmon, the economic value depends on a reduction in expenditures with constant losses, and is estimated to be 0.065?/unit [Formula: see text]/kg production. DISCUSSION: Response to selection for measures of disease prevalence cannot be predicted from quantitative genetic theory alone. Moreover, many studies fail to address the issue of whether genetic improvement results in reduced losses or expenditures. Using [Formula: see text] as the breeding goal trait, weighed by its appropriate economic value, avoids these issues. CONCLUSION: When management is optimized, the economic value increases with decreasing values of [Formula: see text] (until the threshold of [Formula: see text], where it drops to zero). When management is not optimized, the economic value depends on whether genetic improvement is used for reduced expenditures or production losses. For sea lice in salmon, the economic value is estimated to be 0.065 ?/unit [Formula: see text]/kg production. PMID- 30285630 TI - Biotite: a unifying open source computational biology framework in Python. AB - BACKGROUND: As molecular biology is creating an increasing amount of sequence and structure data, the multitude of software to analyze this data is also rising. Most of the programs are made for a specific task, hence the user often needs to combine multiple programs in order to reach a goal. This can make the data processing unhandy, inflexible and even inefficient due to an overhead of read/write operations. Therefore, it is crucial to have a comprehensive, accessible and efficient computational biology framework in a scripting language to overcome these limitations. RESULTS: We have developed the Python package Biotite: a general computational biology framework, that represents sequence and structure data based on NumPyndarrays. Furthermore the package contains seamless interfaces to biological databases and external software. The source code is freely accessible at https://github.com/biotite-dev/biotite . CONCLUSIONS: Biotite is unifying in two ways: At first it bundles popular tasks in sequence analysis and structural bioinformatics in a consistently structured package. Secondly it adresses two groups of users: novice programmers get an easy access to Biotite due to its simplicity and the comprehensive documentation. On the other hand, advanced users can profit from its high performance and extensibility. They can implement their algorithms upon Biotite, so they can skip writing code for general functionality (like file parsers) and can focus on what their software makes unique. PMID- 30285631 TI - Assessment of shared alleles in drought-associated candidate genes among southern California white oak species (Quercus sect. Quercus). AB - BACKGROUND: Hybridization and introgression are common phenomena among oak species. These processes can be beneficial by introducing favorable genetic variants across species (adaptive introgression). Given that drought is an important stress, impacting physiological and morphological variation and limiting distributions, our goal was to identify drought-related genes that might exhibit patterns of introgression influenced by natural selection. Using RNAseq, we sequenced whole transcriptomes of 24 individuals from three oaks in southern California: (Quercus engelmannii, Quercus berberidifolia, Quercus cornelius mulleri) and identified genetic variants to estimate admixture rates of all variants and those in drought genes. RESULTS: We found 398,042 variants across all loci and 4352 variants in 139 drought candidate genes. STRUCTURE analysis of all variants revealed the majority of our samples were assignable to a single species, but with several highly admixed individuals. When using drought associated variants, the same individuals exhibited less admixture and their allele frequencies were more polarized between Engelmann and scrub oaks than when using the total gene set. These findings are consistent with the hypothesis that selection may act differently on functional genes, such as drought-associated genes, and point to candidate genes that are suggestive of divergent selection among species maintaining adaptive differences. For example, the drought genes that showed the strongest bias against engelmannii-fixed oak variants in scrub oaks were related to sugar transporter, coumarate-coA ligases, glutathione S conjugation, and stress response. CONCLUSION: This pilot study illustrates that whole transcriptomes of individuals will provide useful data for identifying functional genes that contribute to adaptive divergence among hybridizing species. PMID- 30285632 TI - A high risk of sleep apnea is associated with less postoperative cognitive dysfunction after intravenous anesthesia: results of an observational pilot study. AB - BACKGROUND: The obstructive sleep apnea syndrome (OSAS) is characterized by temporary cerebral hypoxia which can cause cognitive dysfunction. On the other hand, hypoxia induced neurocognitive deficits are detectable after general anesthesia. The objective of this study was to evaluate the impact of a high risk of OSAS on the postoperative cognitive dysfunction after intravenous anesthesia. METHODS: In this single center trial between June 2012 and June 2013 43 patients aged 55 to 80 years with an estimated hospital stay of at least 3 days undergoing surgery were enrolled. Patients were screened for a high risk of OSAS using the STOP-BANG test. The cognitive function was assessed using a neuropsychological test battery, including the DemTect test for cognitive impairment and the RMBT test for memory, the day before surgery and within 36 h after extubation. RESULTS: Twenty-two of the 43 analyzed patients were identified as patients with a high risk of OSAS. Preoperatively, OSAS patients showed a significant worse performance only for the DemTect (p = 0.0043). However, when comparing pre- and postoperative test results, the OSAS patients did not show a significant loss in any test but significantly improved in RMBT test, whereas the control group showed a significant worse performance in three of eight tests. In five tests, we found a significant difference between the two groups with respect to the change from pre- to postoperative cognitive function. CONCLUSION: Patients with a high risk of OSAS showed a less impairment of memory function and work memory performance after intravenous anesthesia. This might be explained by a beneficial effect of intrinsic hypoxic preconditioning in these patients. PMID- 30285633 TI - Modeling tuberculosis dynamics with the presence of hyper-susceptible individuals for Ho Chi Minh City from 1996 to 2015. AB - BACKGROUND: The depletion of CD4 cell is the underlying reason for TB hyper susceptibility among people with HIV. Consequently, the trend of TB dynamics is usually hidden by the HIV outbreak. METHODS: Here, we aim to evaluate the trend of TB dynamics quantitatively by a simple mathematical model using the known prevalence of hyper-susceptible individuals in the population. In order to estimate the parameters governing transmission we fit this model in a maximum likelihood framework to both reported TB cases and data from samples tested with Interferon Gamma Assay from Ho Chi Minh City - a city with high TB transmission and strong synchronization between HIV/AIDS and TB dynamics. RESULTS: Our results show that TB transmission in HCMC has been declining among people without HIV; we estimate a 18% (95% CI: 9-25%) decline in the transmission parameter between 1996 and 2015. Furthermore, we show that co-infected patients have limited contribution to the transmission process. For hyper-susceptible individuals, our model suggests that the risk of a new active TB infection occurring is significantly higher than the risk of relapsed active TB, while this is not the case for people without hyper-susceptibility. CONCLUSIONS: The increase of TB notifications in Ho Chi Minh City from 1996 to 2008 is evitable when, as occurred, the number of hyper-susceptible individuals increased faster than the decrease of TB transmission rate. The sharp decrease in TB notifications observed in this city from 2008 to 2015 is the combined result of the decrease of TB transmission rate and the decrease of hyper-susceptible individuals in the population. For hyper-susceptible individuals, we propose that the reason for the reduced relapsed active TB risk is HIV treatment delay. According to HIV treatment guidelines issued by Vietnam's Ministry of Health, hyper-susceptible individuals usually have to wait until their CD4 cell count falls under 350 cells/MUl to start ART. Once patients begin ART, they will remain on ART for the rest of their life and thus have greater protection against relapses of TB. We therefore hypothesize that the delay in using ART imposes considerable TB burden on HCMC despite the declining transmission process. PMID- 30285634 TI - Double trouble: visceral leishmaniasis in twins after traveling to Tuscany - a case report. AB - BACKGROUND: Leishmaniasis is endemic in many countries worldwide, with a prevalence of 12 million people infected, and an estimated annual incidence of 500 000 visceral leishmaniasis cases. In Europe visceral leishmaniasis is considered endemic mainly in the Mediterranean countries and cases in non-endemic European countries north of the Alps have primarily been reported in returning travellers. The incubation period is typically described between 6 weeks to 6 months. The cases presented highlight the occurrence of longer incubation periods and illustrate the individual variability for progression from infection to disease. CASE PRESENTATION: We report the cases of 18-months-old twin girls living at the German-Swiss border, who developed visceral leishmaniasis 7 and 15 months after travelling to Tuscany. They presented with fever of unknown origin and pancytopenia. Both had splenomegaly and in the first case haemophagocytic lymphohistiocytosis or leukaemia was initially included in the differential diagnosis. Diagnosis of visceral leishmaniasis was confirmed by presence of intracytoplasmic localised leishmania parasites on bone marrow aspirate and/or positive leishmania serology. Both girls responded well to treatment with liposomal amphotericin B. The mother and two older siblings remained uninfected, while the father was diagnosed to be an asymptomatic carrier. CONCLUSION: Visceral leishmaniasis is an important differential diagnosis for fever of unknown origin and pancytopenia in young children living in countries with endemic disease and highlights the importance of obtaining a detailed travel history. Hemophagocytic lymphohistiocytosis and acute leukaemia present with similar symptoms and consequently are important differential diagnoses. Factors determining progression from infection to disease are not fully understood but younger age seems to be an important risk factor. Screening of siblings from affected individuals therefore may be warranted. PMID- 30285636 TI - Comparing survival functions with interval-censored data in the presence of an intermediate clinical event. AB - BACKGROUND: In the presence of an intermediate clinical event, the analysis of time-to-event survival data by conventional approaches, such as the log-rank test, can result in biased results due to the length-biased characteristics. METHODS: In the present study, we extend the studies of Finkelstein and Nam & Zelen to propose new methods for handling interval-censored data with an intermediate clinical event using multiple imputation. The proposed methods consider two types of weights in multiple imputation: 1) uniform weight and 2) the weighted weight methods. RESULTS: Extensive simulation studies were performed to compare the proposed tests with existing methods regarding type I error and power. Our simulation results demonstrate that for all scenarios, our proposed methods exhibit a superior performance compared with the stratified log-rank and the log-rank tests. Data from a randomized clinical study to test the efficacy of sorafenib/sunitinib vs. sunitinib/sorafenib to treat metastatic renal cell carcinoma were analyzed under the proposed methods to illustrate their performance on real data. CONCLUSIONS: In the absence of intensive iterations, our proposed methods show a superior performance compared with the stratified log rank and the log-rank test regarding type I error and power. PMID- 30285635 TI - Prevalence and genotypes of group A rotavirus among outpatient children under five years old with diarrhea in Beijing, China, 2011-2016. AB - BACKGROUND: Rotavirus is a leading cause of severe diarrheal disease, and one of the common causes of death in children aged under five years old. The dominant epidemic strains may change in different years in the same area. In order to provide evidence for rotavirus epidemic control and inform vaccine development, we analyzed epidemiological patterns and genetic characteristics of rotavirus in Beijing during 2011-2016. METHODS: Stool specimens of outpatient children under five years old were collected from three children's hospitals on a weekly basis. Group A rotavirus antigens were detected using enzyme-linked immunosorbent assay (ELISA) kit. The partial VP4 genes and VP7 genes of rotavirus were both amplified and sequenced. Genotyping and phylogenetic analyses were performed. Logistic regression and Chi-square tests were performed to determine differences across age groups, districts and years in rotavirus prevalence and genotype distribution. RESULTS: A total of 3668 stool specimens from children with acute diarrhea identified through hospital-based surveillance were collected from 2011 to 2016 in Beijing. A total of 762 (20.8%) specimens tested positive for rotavirus. The rotavirus-positive rate was highest among the 1-2 years old age group (29.0%, 310/1070). November, December and January were the highest rotavirus-positive rate months each year. G9 was the most common G genotype (64.4%, 461/716), and P [8] was the most common P genotype (87.0%, 623/716) among the 716 rotavirus-positive specimens. G9P [8], G3P [8] and G2P [4] were the most common strains. The rotavirus-positive rates of samples in 2012 and 2013 were higher than that in 2011, and the dominant genotype changed from G3P [8] to G9P [8] in 2012 and 2013. VP7 gene sequences of G9 strains in this study clustered into two main lineages. Most of the G9 strains exhibited the highest nucleotide similarity (99.1%~ 100.0%) to the strain found in Japan (MI1128). VP4 gene sequences of P [8] strains were almost P[8]b. CONCLUSIONS: Rotavirus accounted for more than one fifth of childhood diarrhea in Beijing during the study period. Targeted measures such as immunization with effective rotavirus vaccines should be carried out to reduce the morbidity and mortality due to rotavirus. PMID- 30285637 TI - Long-term evaluation of the implementation of a large fall and fracture prevention program in long-term care facilities. AB - BACKGROUND: Falls and fractures are extremely frequent in long-term care facilities (LTCFs). Therefore, a fall and fracture prevention program was started in nearly 1000 LTCFs in Bavaria/Germany between 2007 and 2010. The components of the program were exercise classes, the documentation of falls, environmental adaptations, medication reviews, the recommendation to use hip protectors and education of staff. The present study aimed to provide a comprehensive evaluation of the implementation process of the program regarding results of the implementation phase and the follow-up of 3-9 years after start of implementation. METHODS: Data from numerous sources were used, including data from published studies, statistical data, health insurance claims data and unpublished data from an online questionnaire. To incorporate different aspects, time periods and results, the RE-AIM framework was applied. RESULTS: The program was adopted by 942 of the 1150 eligible LTCFs and reached about 62,000 residents. During the implementation phase exercise classes and recommendation about environmental adaptations were offered in nearly all LTCFs. 13.5% of the residents participated in exercise classes. Hip protectors were available for 9.2% of all residents. In the first implementation wave, femoral fracture rate was significantly reduced by 18% in the first year. At follow-up nearly 90% of all LTCFs still offered exercise classes, which were attended by about 11% of residents. However, only 10% of the exercise classes completely fulfilled the requirements of an effective strength and balance training. Individual advice about environmental adaptations was provided in 74.3% of the LTCFs and nearly all LTCFs claimed to offer hip protectors to their residents. A long-term effect of the program on femoral fractures could not be detected. CONCLUSIONS: The program did not affect the femoral fracture rate in the long run. Possible reasons could be a high turn-over of the staff, a reduced fidelity of training components or a shift in daily priorities among the staff. PMID- 30285638 TI - A comparison of pyogenic liver abscess in patients with or without diabetes: a retrospective study of 246 cases. AB - BACKGROUND: Pyogenic liver abscess(PLA) has become common in patients with diabetes mellitus (DM), but it is unclear whether differences exist between patients with and without DM. A retrospective study was performed to identify these differences, summarize the clinical experience, and improve the diagnosis and treatment of PLA. METHODS: The patients were enrolled in a teaching hospital from January 2012 to December 2016. The patients were separated into two groups based on comorbidity with diabetes mellitus (DM). The DM group was further separated into two subgroups according to the HbA1C concentration to investigate whether glycaemic control affected the clinical characteristics of PLA patients with DM. Chi-square, Fisher's exact test, and t-tests were used to analyse and evaluate differences between the two groups. RESULTS: Two hundred and forty-six PLA patients were identified and 90 (36.6%) had comorbid DM. Patients with DM were older, had higher levels of alkaline phosphatase and gamma-glutamyl transferase, hypertension, a loss of body weight, a single abscess, and combined antibiotic therapy with the use of carbapenems and Klebsiella pneumoniae in their blood cultures but a less frequent history of abdominal surgery and Escherichia coli in their pus cultures. When DM patients were compared to non-DM patients, each of these differences was significant (P < 0.05). Diabetic PLA patients with poor glycaemic control had a significantly higher proportion of fever and both lobes abscess(P < 0.05). CONCLUSION: PLA patients with diabetes are older, have more serious complications, a higher prevalence of cardiovascular disease, an increased use of combined antibiotic therapy with carbapenem, and K. pneumoniae as the predominant pathogen, but these patients had fewer abdominal surgeries and fewer E. coli infections. In addition, poorly controlled glycaemia in diabetic PLA patients is associated with high incidence of fever and both lobes abscess. PMID- 30285639 TI - Identification of risk factors for pancreatic pseudocysts formation, intervention and recurrence: a 15-year retrospective analysis in a tertiary hospital in China. AB - BACKGROUND: Pancreatic pseudocyst (PPC) is a common complication of acute and chronic pancreatitis. To our knowledge no study has systematically reported the risk factors for the formation, intervention and recurrence of PPC. Therefore, the present study aimed to investigate the potential risk factors for PPC, with regards to its formation, intervention and recurrence. METHODS: A database containing 5106 pancreatitis patients was retrospectively analyzed. As a result, a total of 4379 eligible patients were identified and divided into 2 groups: PPC group (group A, n = 759) and non-PPC group (group B, n = 3620). The PPC group was subdivided into 2 groups: intervention PPC (group C, n = 347) and resolution PPC (group D, n = 412). The differences in surgical complication and recurrence rates were compared among 347 PPC patients receiving different interventions, including surgical, endoscopic and percutaneous drainages. Furthermore, group C was subdivided into 2 groups: recurrent PPC (group E, n = 34) and non-recurrent PPC (group F, n = 313). All possible risk factors for PPC formation, intervention and recurrence were determined by multivariate regression analysis. RESULTS: In this study, PPC was developed in 17.3% (759/4379) of pancreatitis patients. The significant risk factors for PPC formation included alcoholic pancreatitis (OR, 6.332; 95% CI, 2.164-11.628; p = 0.031), chronic pancreatitis (CP) (OR, 5.822; 95% CI, 1.921-10.723; p = 0.006) and infected pancreatic necrosis (OR, 4.253; 95% CI, 3.574-7.339; p = 0.021). Meanwhile, the significant risk factors of PPC patients who received intervention were alcoholic pancreatitis (OR, 7.634; 95% CI, 2.125-13.558; p = 0.016), size over 6 cm (OR, 8.834; 95% CI, 2.017-16.649; p = 0.002) and CP (OR, 4.782; 95% CI, 1.897-10.173; p = 0.038). In addition, the recurrence rate in PPC patients treated with percutaneous drainage was found to be the highest (16.3%) among the three intervention groups. Furthermore, percutaneous drainage was the only risk factor of PPC recurrence (OR, 7.812; 95% CI, 3.109-23.072; p = 0.013) identified from this retrospective cohort study. CONCLUSIONS: Alcoholic pancreatitis and CP are the main risk factors for PPC formation and intervention, but not PPC recurrence. A higher recurrence rate is found in PPC patients treated with percutaneous drainage, as compared to endoscopic and surgical interventions. PMID- 30285640 TI - Relationship of ideal cardiovascular health metrics with retinal vessel calibers and retinal nerve fiber layer thickness: a cross-sectional study. AB - BACKGROUND: Ideal cardiovascular health (CVH) metrics have been found to be associated with subclinical vascular abnormalities. However, the relationship between ideal CVH metrics and retinal vessel calibers and retinal nerve fiber layer (RNFL) thickness in a Chinese population is unknown. METHODS: We collected information on the seven ideal CVH metrics among 3376 participants aged 40 years or older from the Asymptomatic Polyvascular Abnormalities Community Study in 2012. Retinal vessel calibers and RNFL thickness were assessed by retinal photography and spectral-domain optical coherence tomography. Multivariable linear models were used to analyze the relationship between ideal CVH metrics and retinal parameters. RESULTS: With the decreased number of ideal CVH metrics, central retinal arteriolar equivalents (CRAE) was significantly narrowed and arterio- venous ratio (AVR) significantly decreased (p < 0.0001). While the RNFL thickness and central retinal venous equivalents (CRVE) showed no significant changes with the decreased ideal CVH metrics. Linear regression showed that both CRAE and AVR was positively related with the number of ideal CVH metrics (regression coefficient beta: 0.806, 95% confidence interval (CI): 0.266-1.346 for CRAE (micron); and regression coefficient beta: 0.005, 95% CI: 0.002-0.009 for AVR) after adjusting for age (year), sex = male (n), education (n), average monthly income (Y) and other related risk factors. CONCLUSIONS: These findings suggested a clear positive relationship between the number of ideal CVH metrics and CRAE and AVR in Chinese population, supporting the importance of ideal health behaviors and factors in subclinical vascular abnormalities prevention. PMID- 30285641 TI - Identifying and understanding the health and social care needs of older adults with multiple chronic conditions and their caregivers: a scoping review. AB - BACKGROUND: As the population is aging, the number of persons living with multiple chronic conditions (MCC) is expected to increase. This review seeks to answer two research questions from the perspectives of older adults with MCC, their caregivers and their health care providers (HCPs): 1) What are the health and social care needs of community-dwelling older adults with MCC and their caregivers? and 2) How do social and structural determinants of health impact these health and social care needs? METHODS: We conducted a scoping review guided by a refinement of the Arksey & O'Malley framework. Articles were included if participants were 55 years or older and have at least two chronic conditions. We searched 7 electronic databases. The data were summarized using thematic analysis. RESULTS: Thirty-six studies were included in this review: 28 studies included participants with MCC; 12 studies included HCPs; 5 studies included caregivers. The quality of the studies ranged from moderate to good. Five main areas of needs were identified: need for information; coordination of services and supports; preventive, maintenance and restorative strategies; training for older adults, caregivers and HCPs to help manage the older adults' complex conditions; and the need for person-centred approaches. Structural and social determinants of health such as socioeconomic status, education and access influenced the needs of older adults with MCC. CONCLUSION: The review highlights that most of the needs of older adults with MCC focus on lack of access to information and coordination of care. The main structural and social determinants that influenced older adults' needs were their level of education/health literacy and their socioeconomic status. PMID- 30285642 TI - Using an introduced index to assess the association between food diversity and metabolic syndrome and its components in Chinese adults. AB - BACKGROUND: It is reported that an increase in food diversity would lower the risk of cardiac-cerebral vascular diseases. METHODS: A new index was introduced to develop a Chinese healthy food diversity (HFD) index, exploring the association with metabolic syndrome (MetS) and its components among Chinese adults. Two sets of data were used. The primary data were from a cross-sectional survey conducted in 2016 called the Chinese Urban Adults Diet and Health Study (CUADHS); the verification data were from the China Health and Nutrition Survey (CHNS) of 2009. The Chinese HFD index was developed according to the Chinese Dietary Guideline, with food consumption information from 24-h dietary recalls. The association between the index and MetS and its components was explored in logistic regression models. RESULTS: Among 1520 participants in the CUADHS, the crude prevalence of MetS was 36.4%, which was 29.0% after the standardisation of age and gender by the 2010 Chinese national census. In the CUADHS, the HFD index ranged from 0.04 to 0.63. The value of the index among participants who are male, young, poorly educated, drinking or smoking, and with high energy intakes was significantly lower than that of their counterparts. In the verification dataset of the CHNS, there were 2398 participants, and the distribution of different genders and age groups was more balanced. The crude prevalence of MetS in the CHNS was 27.3% and the standardised prevalence was 19.5%. The Chinese HFD index ranged from 0.02 to 0.62. In the CUADHS, the Chinese HFD index was not significantly associated with MetS in covariate-adjusted models or with its components. In the CHNS, the Chinese HFD index had a significantly negative correlation with MetS and its components (i.e., elevated fasting glucose and elevated waist circumference) in covariate-adjusted models. CONCLUSIONS: Increased food diversity may decrease the risk of MetS, which is important in dietary interventions of cardiac-cerebral vascular disease. This underscores the necessity of continued investigation into the role of HFD in the prevention of MetS and provides an integral framework for ongoing research. PMID- 30285643 TI - A descriptive analysis of non-Cochrane child-relevant systematic reviews published in 2014. AB - BACKGROUND: Consumers, clinicians, policymakers and researchers require high quality evidence to guide decision-making in child health. Though Cochrane systematic reviews (SRs) are a well-established source of evidence, little is known about the characteristics of non-Cochrane child-relevant SRs. To complement published descriptions of Cochrane SRs, we aimed to characterize the epidemiologic, methodological, and reporting qualities of non-Cochrane child relevant SRs published in 2014. METHODS: English-language child-relevant SRs of quantitative primary research published outside the Cochrane Library in 2014 were eligible for this descriptive analysis. A research librarian searched MEDLINE, CINAHL, Web of Science, and PubMed in August 2015. A single reviewer screened articles for inclusion; a second verified the excluded studies. Reviewers extracted: general characteristics of the review; included study characteristics; methodological approaches. We performed univariate analyses and presented the findings narratively. RESULTS: We identified 1598 child-relevant SRs containing a median (IQR) 19 (11, 33) studies. These originated primarily from high-income countries (n = 1247, 78.0%) and spanned 47 of the 53 Cochrane Review Groups. Most synthesized therapeutic (n = 753, 47.1%) or epidemiologic (n = 701, 43.8%) evidence. Though 39.3% (n = 628) of SRs included evidence related to children only, few were published in pediatric-specific journals (n = 283, 17.7%). Reporting quality seemed poor based on the items we assessed; few reviews mentioned an a-priori protocol (n = 246, 15.4%) or registration (n = 111, 6.9%), and only 23.4% (n = 374) specified a primary outcome. Many SRs relied solely on evidence from non-RCTs (n = 796, 49.8%). Less than two-thirds (n = 953, 59.6%) appraised the quality of included studies and assessments of the certainty of the body of evidence were rare (n = 102, 6.4%). CONCLUSIONS: Child-relevant Cochrane SRs are a known source of high quality evidence in pediatrics. There exists, however, an abundance of evidence from non-Cochrane SRs that may be complementary. Our findings show that high-quality non-Cochrane SRs may not be practical nor easy for knowledge users to find. Improvements are needed to ensure that evidence syntheses published outside of the Cochrane Library adhere to the high standard of conduct and reporting characteristic of Cochrane SRs. PMID- 30285644 TI - The value of shock index in prediction of cardiogenic shock developed during primary percutaneous coronary intervention. AB - BACKGROUND: Shock index(SI) is a conventional predictive marker for haemodynamic state. Its breakpoint varies by different conditions according to previous studies. The current study was performed to evaluate the capability of SI in prediction of cardiogenic shock(CS) developed during primary percutaneous coronary intervention (pPCI). METHODS: Total 870 patients of ST segment elevation myocardial infarction(STEMI) who were haemodynamic stable before pPCI were involved in the study. In this cohort, 625 consecutive patients composed analysis series and 245 consecutive patients composed validation series. Multivariate regression analysis was used to evaluate whether SI was a significant predictor of developed CS and Hosmer-Lemeshow test was used to assess the goodness of model fitness. Receiver-operating characteristics (ROC) analysis was used to compare the predictive capability of SI with other predictors. The sensitivity, specificity, accuracy, positive and negative predictive values of SI at different cutoff values was compared to identify a best breakpoint. RESULTS: In the analysis series, SI and Killips classification were identified as independent predictors. ROC analysis demonstrated the diagnostic capability of SI was superior to pre-procedural systolic blood pressure(SBP) or heart rate(HR) alone (0.8113 vs 0.7582, P = 0.04 and 0.8113 vs 0.7111, P < 0.001). The diagnostic capability of SI was equivalent to that of combination of SBP, HR and Killips claasification(0.8133 vs 0.8137, P = 0.97). SI had a high specificity and low sensitivity. When the cutoff value was set at 0.93, the positive predictive value, negative predictive value and diagnostic accuracy was 42.6%, 95.1% and 87.4% respectively. In validation series, the area under ROC curve was 0.8245, which was similar to that in the analysis series. The positive predictive value, negative predictive value and diagnostic accuracy at the cutoff value of 0.93 was 53.8%, 93.2% and 88.9% respectively. CONCLUSIONS: SI has a high predictive accuracy for developing CS during pPCI in STEMI patients. It is an excellent exclusion diagnosis index rather than confirmative diagnosis index. PMID- 30285645 TI - Effects of 12-month home-based physiotherapy on duration of living at home and functional capacity among older persons with signs of frailty or with a recent hip fracture - protocol of a randomized controlled trial (HIPFRA study). AB - BACKGROUND: Health concerns, such as frailty and osteoporotic fractures decrease functional capacity and increase use of health and social care services in the aging population. The ability to continue living at home is dependent on functional capacity, which can be enhanced by rehabilitation. We study the effects of a 12-month home-based physiotherapy program with 12-month follow-up on duration of living at home, functional capacity, and the use of social and health care services among older persons with signs of frailty, or with a recently operated hip fracture. METHODS: This is a non-blinded, parallel group, randomized controlled trial performed in South Karelia Social and Health Care District, Finland (population 131,000). Three hundred community-dwelling older persons with signs of frailty (age >= 65) and 300 persons with a recent hip fracture (age >= 60) will be recruited. Frailty is screened by FRAIL questionnaire and verified by modified Fried's frailty criteria. Both patient groups will be randomized separately to a physiotherapy and a usual care arm. Individualized, structured and progressive physiotherapy will be carried out for 60 min, twice a week for 12 months at the participant's home. The primary outcome at 24 months is duration of living at home. Our hypothesis is that persons assigned to the physiotherapy arm will live at home for six months longer than those in the usual care arm. Secondary outcomes are functional capacity, frailty status, health-related quality-of-life, falls, use and costs of social and health care services, and mortality. Assessments, among others Short Physical Performance Battery, Functional Independence Measure, Mini Nutritional Assessment, and Mini-Mental State Examination will be performed at the participant's home at baseline, 3, 6, and 12 months. Register data on the use and costs of social and health care services, and mortality will be monitored for 24 months. DISCUSSION: Our trial will provide new knowledge on the potential of intensive, long-term home-based physiotherapy among older persons at risk for disabilities, to enhance functional capacity and thereby to postpone the need for institutional care, and diminish the use of social and health care services.

PMID- 30285646 TI - Deep learning based low-cost high-accuracy diagnostic framework for dementia using comprehensive neuropsychological assessment profiles. AB - BACKGROUND: The conventional scores of the neuropsychological batteries are not fully optimized for diagnosing dementia despite their variety and abundance of information. To achieve low-cost high-accuracy diagnose performance for dementia using a neuropsychological battery, a novel framework is proposed using the response profiles of 2666 cognitively normal elderly individuals and 435 dementia patients who have participated in the Korean Longitudinal Study on Cognitive Aging and Dementia (KLOSCAD). METHODS: The key idea of the proposed framework is to propose a cost-effective and precise two-stage classification procedure that employed Mini Mental Status Examination (MMSE) as a screening test and the KLOSCAD Neuropsychological Assessment Battery as a diagnostic test using deep learning. In addition, an evaluation procedure of redundant variables is introduced to prevent performance degradation. A missing data imputation method is also presented to increase the robustness by recovering information loss. The proposed deep neural networks (DNNs) architecture for the classification is validated through rigorous evaluation in comparison with various classifiers. RESULTS: The k-nearest-neighbor imputation has been induced according to the proposed framework, and the proposed DNNs for two stage classification show the best accuracy compared to the other classifiers. Also, 49 redundant variables were removed, which improved diagnostic performance and suggested the potential of simplifying the assessment. Using this two-stage framework, we could get 8.06% higher diagnostic accuracy of dementia than MMSE alone and 64.13% less cost than KLOSCAD-N alone. CONCLUSION: The proposed framework could be applied to general dementia early detection programs to improve robustness, preciseness, and cost effectiveness. PMID- 30285647 TI - Epidemiology of Paediatric constipation in Indonesia and its association with exposure to stressful life events. AB - BACKGROUND: We aimed to study the epidemiology and risk factors, including exposure to emotional stress, for constipation in Indonesian children and adolescents of 10-17 year age group. METHODS: A cross-sectional survey using a validated, self-administered questionnaire was conducted in randomly selected children and adolescents in nine state junior high schools from five districts of Jakarta. All of them were from urban areas. Constipation was defined as a diagnosis by using the Rome III criteria. RESULTS: Of 1796 children included in the analysis, 328 (18.3%; 95% CI 016-0.2) had constipation. Females and those residing in North Jakarta showed risks associated with constipation in school-age children and adolescents. Symptoms independently associated with constipation were abdominal pain (64% vs 43.3% of control) and straining (22.9% vs 6.3%). The prevalence of constipation was significantly higher in those with stressful life events such as father's alcoholism (adjusted OR 1.91, 95% CI 1.27-2.89, P = 0.002), severe illness of a close family member (adjusted OR 1.77, 95% CI 1.12 2.80, P = 0.014), hospitalization of the child for another illness (adjusted OR 1.68, 95% CI 1.22-2.31, P < 0.001), being bullied at school (adjusted OR 1.67, 95% CI 1.01-2.76, P = 0.047) and loss of a parent's job (adjusted OR 1.39, 95% CI 1.03-1.88, P = 0.034). CONCLUSIONS: Constipation in children and adolescent is a significant health problem, affecting almost 20% of Indonesian school-age children and adolescents. Common school and home related stressful life events appear to have predisposed these children to develop constipation. PMID- 30285648 TI - Identity and validity of conserved B cell epitopes of filovirus glycoprotein: towards rapid diagnostic testing for Ebola and possibly Marburg virus disease. AB - BACKGROUND: Ebolavirus and Marburgvirus are genera of the virus family Filoviridae. Filoviruses cause rare but fatal viral hemorrhagic fevers (VHFs) in remote villages of equatorial Africa with potential for regional and international spread. Point-of-care (POC) rapid diagnostic tests (RDTs) are critical for early epidemic detection, reponse and control. There are 2 RDTs for Zaire ebolavirus (EBOV), but not other Ebolavirus spp. or Marburg marburgvirus (MARV). We validate 3 conserved B cell epitopes of filovirus glycoprotein (GP) using ebola virus diseases (EVD) survivor samples, towards devising pan-filovirus RDTs. METHODS: In-silico Immuno-informatics:- (a) multiple and basic local alignments of amino-acid sequences of filovirus (4 Ebolavirus spp. & MARV) Gp1, 2 and epitope prediction and conservation analyses within context of ClusterW, BLAST-P and the immune epitope database analysis resource (IEDB-AR); alongside (b) in-vitro enzyme immuno-assays (EIAs) for SUDV Gp1, 2 antigen and host specific antibodies (IgM and IgG) among 94 gamma irradiated EVD survivor serum and 9 negative controls. RESULTS: Linear B cell epitopes were present across the entire length of all Gp1, 2, most lying in the region between amino acids positioned 350 and 500. Three seperate epitopes 97/80_GAFFLYDRLAST, 39_YEAGEWAENCY and 500_CGLRQLANETTQALQLFLRATTELR (designated UG-Filo-Peptide- 1, 2 and 3 respectively) were conserved within all studied filovirus species Gp1, 2. Gp1, 2 host specific IgM levels were comparably low (av. ODs < 0.04 [95% CI: 0.02837 to 0.04033]) among the 9 negative controls and 57 survivor samples analyzed. Host specific IgG levels, on the other hand, were elevated (av. ODs > 1.7525 [95% CI: 0.3010 to 3.1352]) among the 92 survivor samples relative to the 9 negative controls (av. ODs < 0.2.321 [95% CI: -0.7596 to 0.5372]). Filovirus Gp1, 2 antigen was not detected [av. ODs < 0.20] within EVD survivor serum relative to recombinant protein positive controls [av. ODs = 0.50]. CONCLUSIONS: These conserved B cell epitopes of filovirus Gp1, 2 and their derivative antibodies are promising for research and development of RDTs for EVD, with potential for extension to detect MVD. PMID- 30285649 TI - Biochemical and molecular characterization of adult patients with type I Gaucher disease and carrier frequency analysis of Leu444Pro - a common Gaucher disease mutation in India. AB - BACKGROUND: Gaucher disease is a rare pan-ethnic disorder which occurs due to an increased accumulation of undegraded glycolipid glucocerebroside inside the cells' lysosomes. A beta-Glucosidase (GBA) gene defect results in glucocerebrosidase enzyme deficiency. Though the disease is mainly diagnosed in childhood, the adult manifestation is often missed or identified late due to the failure to recognize the heterogeneous clinical presentation. The present study includes seven unrelated Indian adult patients (age range: 20-40 years) having splenomegaly, with or without hepatomegaly, cytopenia and bone abnormality. METHODS: The biochemical investigation implicated measuring plasma chitotriosidase enzyme activity followed by confirmatory test of beta-Glucosidase enzyme activity from the leukocytes. The molecular characterization involved patients' initial screening for the common Gaucher mutation (Leu444Pro). Later, all patients were subjected to whole GBA gene coding region study using bidirectional Sanger sequencing. The population screening for common Gaucher disease mutation (Leu444Pro) was executed in 1200 unrelated and healthy Indian subjects by Restriction Fragment Length Polymorphism-Polymerase Chain Reaction technique. The allele frequency was calculated using Hardy-Weinberg formula. RESULTS: The biochemical analysis revealed a significant reduction in the beta Glucosidase activity in all the patients. Also, an elevated level of plasma Chitotriosidase activity in five patients supported their diagnosis of Gaucher disease. Sanger sequencing established four patients with homozygous variation and three patients with compound heterozygous variation in GBA gene. This study uncovers two missense variants (Ala448Thr and Val17Gly) not previously reported in Gaucher disease patients. Also the known mutations like Leu444Pro, Arg329Cys, Asp315Asn, Ser125Arg, and Arg395Cys were identified in these patients. The homology modeling suggested the destabilization of the protein structure due to novel variants. The Leu444Pro mutation screening in the Indian population spotted two people as a carrier. This emerged the carrier frequency of 1:600 along with wild-type allele frequency 0.97113 and mutant allele frequency 0.02887. CONCLUSIONS: The study reports novel and known variants identified in the GBA gene in seven adult patients. The given study is the first report on the carrier frequency of the Leu444Pro mutant allele in an Indian population which will help understanding the burden and susceptibility of Gaucher disease to affect next generation in India. PMID- 30285650 TI - Emergency response time and pre-hospital trauma survival rate of the national ambulance service, Greater Accra (January - December 2014). AB - BACKGROUND: Every year, about 1.2 million people die through road traffic crashes worldwide. Majority of these deaths occur in Africa where most of their emergency medical services are underdeveloped. In 2004, Ghana established the National Ambulance Council to provide timely and efficient pre-hospital emergency medical care to the sick and injured. Pre-hospital emergency medical service is essential for accident victims since it has the potential of saving lives. The study sought to determine the relationship between pre-hospital trauma survival rate and response time to emergencies and factors associated to pre-hospital trauma survival in Accra, Ghana. METHODS: The study was a cross sectional study which reviewed pre-hospital care forms of trauma patients from the fourteen ambulance stations in the Greater Accra region from January to December 2014. Data were extracted from these forms and the response time estimated. Conscious patients who were alert were categorized as responsive under the AVPU scale. The proportion of patients who survived pre-hospital trauma and the time pre hospital trauma cases were responded to was estimated. Multiple logistic regression analysis was conducted to determine which variables were associated with survival. RESULTS: A total of 652 pre-hospital care forms were reviewed. About 87% survived pre-hospital trauma. The average response time to patients was (16.9 +/- 0.7) minutes and the median transportation time of the patient was 82 min. Level of consciousness of a patient and response time of patients transported was found to be significantly associated with pre-hospital trauma survival. CONCLUSION: There was a high trauma patient survival rate among victims attended to by an NAS. The average response time in Greater Accra region in the 14 ambulance stations is 16.9 min which is not different from the 17 min recorded in 2013 by NAS. Factors that were associated with pre-hospital survival were alertness in the level of consciousness and response time less than 17 min. PMID- 30285651 TI - Hepatic expression of Yin Yang 1 (YY1) is associated with the non-alcoholic fatty liver disease (NAFLD) progression in patients undergoing bariatric surgery. AB - BACKGROUND: This study is to investigate the association between the hepatic expression of Yin Yang 1 (YY1) and the progression of non-alcoholic fatty liver disease (NAFLD) in patients undergoing bariatric surgery. METHODS: Obese patients undergoing bariatric surgery were included. Liver tissues were subjected to the quantitative real-time PCR, Western blot analysis, and immunohistochemical assay, to determine the expression levels of YY1. RESULTS: Totally 88 patients were included. According to the NAFLD activity score (NAS), these patients were divided into the control (n = 12), steatosis (n = 20), non-defining NASH (n = 38), and NASH (n = 18) groups. Significant differences in the serum glucose, insulin, ALT, AST, and HOMA-IR levels were observed among these different NAFLD groups. Hepatic YY1 expression had correlation with serum glucose, insulin, HOMA IR, ALT, AST, triglycerides, HDL, and GGT. Immunohistochemical analysis showed that, compared with the control group, the expression levels of YY1 were significantly higher in the non-defining NASH and NASH groups. In addition, multivariate regression model showed that the serum ALT and YY1 levels were strongly associated with the NAFLD activity. CONCLUSIONS: Several factors are associated with NAFLD progression, including the expression of YY1. Our findings contribute to understanding of the pathogenesis of NAFLD. TRIAL REGISTRATION: NCT03296605 , registered on September 28, 2017. PMID- 30285652 TI - Quantifying the effects of aging and urbanization on major gastrointestinal diseases to guide preventative strategies. AB - BACKGROUND: This study aimed to quantify the effects of aging and urbanization on major gastrointestinal disease (liver cirrhosis, hepatitis B, diarrhea, liver cancer, stomach cancer, pancreas cancer, hepatitis C, esophagus cancer, colon/rectum cancer, gastrointestinal ulcers, diabetes, and appendicitis). METHODS: We accessed 2004 and 2011 mortality statistics from the most developed cities and least developed rural areas in China using a retrospective design. The relative risk of death associated with urbanization and age was quantified using Generalized linear model (the exp.(B) from model is interpreted as the risk ratio; the greater the B, the greater the impact of urbanized factors or aging factor or effect of aging factor with urbanization). The interaction between region (cities and rural areas) and age was considered as indicator to assess role of age in mortality with urbanization. RESULTS: Greater risk of disease with urbanization were, in ascending order, for diabetes, colon/rectum cancer, hepatitis C and pancreas cancer. Stronger the effect of aging with urbanization were, in ascending order, for stomach cancer, ulcer, liver cancer, colon/rectum cancer, pancreas cancer, diabetes, hepatitis C, appendicitis and diarrhea. When the effects of aging and urbanization on diseases were taken together as the dividing value, we were able to further divide the 12 gastrointestinal diseases into three groups to guide the development of medical strategies. CONCLUSIONS: It was suggested that mortality rate for most gastrointestinal diseases was sensitive to urbanization and control of external risk factors could lead to the conversion of most gastrointestinal disease. PMID- 30285654 TI - A first CLN6 variant case of late infantile neuronal ceroid lipofuscinosis caused by a homozygous mutation in a boy from China: a case report. AB - BACKGROUND: Neuronal ceroid lipofuscinosis (NCLs) are lysosomal storage disorders characterized by seizures, motor impairment, and loss of vision. Ceroid lipofuscinosis (CLN) gene mutations are the cause, but NCL cases arising from CLN6 mutations have not been described in China to date. The CLN6 protein, which plays a role in lysosomal function, is an endoplasmic reticulum (ER) membrane protein with seven transmembrane (TM) domains. It has a cytosolic-facing amino terminal domain and a luminal-facing carboxyl terminal domain, with six loops between the TM domains. CASE PRESENTATION: Here we report a case involving a Chinese boy whose suspected diagnosis was a hereditary leukoencephalopathy, based on brain MRI imaging and epilepsy symptoms, language articulation disorders, ataxia, and unstable gait. The electroencephalogram showed epileptic discharges, and the brain MRI scan showed high signal intensity adjacent to the bilateral posterior horns of the lateral ventricles on T2-weighted images, along with cerebellar atrophy. Using next-generation sequencing for the genes in a panel for hereditary leukoencephalopathies, we detected a homozygous missense point mutation c.892G > A(p.Glu298Lys) in CLN6, and the variant was interpreted as pathogenic on in silico analysis. Absence of this mutation was confirmed in 259 controls. Late infantile NCL and secondary epilepsy were diagnosed, and oral sodium valproate was prescribed. The epilepsy was not well controlled, however, and the other signs had not improved at the 6-month follow-up. We also analyzed the loci of 31 CLN6 missense mutations, including those previously reported and the current one. We found that 22.6% (7/31) of the mutations are in the cytoplasmic domains, about 32.2% (10/31) are in the TM domains, and about 45.2% (14/31) are in the luminal domains. These mutations were mostly located in the TM3-TM4 loop (6/31), TM1-TM2 loop (4/31), and C-terminus (4/31), with none found in the TM4-TM5 loop, TM5-TM6 loop, or TM7. CONCLUSIONS: We report the first case in China of NCL caused by a CLN6 mutation, expanding the genotype options for NCLs. In practice, NCLs generally are not the initial suspected diagnosis for such cases. Use of a gene sequencing panel for investigating unexplained seizures or leukoencephalopathies can help confirm the diagnosis. PMID- 30285653 TI - Development of a sandwich ELISA to detect Leishmania 40S ribosomal protein S12 antigen from blood samples of visceral leishmaniasis patients. AB - BACKGROUND: Visceral leishmaniasis (VL), caused by Leishmania donovani complex parasites, is a neglected parasitic disease that is generally fatal if untreated. Despite decades of research to develop a sensitive VL diagnostic test, definitive diagnosis of VL still mainly relies on the visualization of the parasite in aspirates from the spleen, liver or bone marrow, an invasive and dangerous process with variable sensitivity. A sensitive assay that can detect Leishmania antigen from blood samples will help confirm cause, cure or recurrence of VL. METHODS: In this study, rabbit polyclonal antibodies were raised against eight recombinant Leishmania proteins that are highly abundant in Leishmania. The antibodies were purified and labeled with biotin for developing a prototype sandwich enzyme-linked immunosorbent assay (ELISA). RESULTS: The ELISA for the Leishmania 40S ribosomal protein S12 detected target antigen with the highest sensitivity and specificity and could detect 1 pg of purified protein or as few as 60 L. donovani parasites. The 40S ribosomal protein S12 sandwich ELISA could detect the target antigen from Peripheral Blood Mononuclear Cell (PBMC) samples in 68% of VL patients and post-kala-azar dermal leishmaniasis (PKDL) patients, providing an estimation of parasitemia ranging from 15 to 80 amastigotes per ml of blood. CONCLUSION: These results indicate that the 40S ribosomal protein S12 sandwich ELISA warrants further tests with more clinical samples of VL patients and other parasitic diseases. It is hopeful that this ELISA could become a useful tool for confirming VL diagnosis, monitoring treatment progress, disease recurrence and possibly detecting asymptomatic Leishmania infections with a high parasite load. PMID- 30285655 TI - Long-term survival in Japanese renal transplant recipients with Alport syndrome: a retrospective study. AB - BACKGROUND: Patients with Alport syndrome (AS) develop progressive kidney dysfunction due to a hereditary type IV collagen deficiency. Survival of the kidney allograft in patients with AS is reportedly excellent because AS does not recur. However, several studies have implied that the type IV collagen in the GBM originates from podocytes recruited from the recipient's bone marrow-derived cells, suggesting the possibility of AS recurrence. Limited data are available regarding AS recurrence and graft survival in the Japanese population; the vast majority were obtained from living related kidney transplantation (LRKTx). METHODS: In this retrospective study, twenty-one patients with AS were compared with 41 matched patients without AS from 1984 to 2015 at two centers using propensity scores. Nineteen of the 21 patients with AS underwent LRKTx. The mean post-transplant follow-up period was 83 months in the AS group and 110 months in the control group. Histopathological AS recurrence was assessed by immunoreactivity of alpha5 (type IV collagen) antibody and electron microscopy. RESULTS: The graft survival rate was equivalent between patients with and without AS (86.7% vs. 77.1% and 69.3% vs. 64.2% at 5 and 10 years; p = 0.16, log-rank test). Immunoreactivity to alpha5 antibody showed strong linear positivity with no focal defect in six patients. Electron microscopy showed no GBM abnormalities in two patients who were exhibiting long-term kidney allograft survival. CONCLUSIONS: We confirmed that alpha5 and the GBM structure were histopathologically maintained in the long term after kidney transplantation. The patient and graft survival rates were equivalent between Japanese patients with and without AS. PMID- 30285656 TI - Prognostic value of the fibrinogen/albumin ratio (FAR) in patients with operable soft tissue sarcoma. AB - BACKGROUND: Coagulation and nutrition play important roles in cancer progression. The aim of the present study is to evaluate the prognostic value of the preoperative fibrinogen/albumin ratio (FAR) in surgical patients with soft tissue sarcoma (STS) and to compare this value with other inflammatory biomarkers. In addition, we investigated the relationship between FAR and the clinicopathological characteristics of STS patients. METHODS: We included 310 STS patients in this retrospective study. Kaplan-Meier curves, univariate and multivariate Cox proportional models were used in the prognostic analyses. RESULTS: According to the receiver operating characteristic (ROC) analysis, the optimal FAR cut-off value was 0.0726. The FAR exhibited a greater area under the curve (AUC) value (0.680) than did the NLR and PLR. An elevated FAR (>=0.0726) was significantly associated with an old age, large tumor size, deep tumor location, high tumor grade, and advanced American Joint Committee on Cancer (AJCC) stage. Patients with an increased FAR had a shorter median survival time and a lower 5-year overall survival (OS) rate than did those with a low FAR (61.0 vs115.8 months, P < 0.001; 56.7% vs 82.4%, P < 0.001, respectively). Multivariate analysis indicated FAR (Hazard ratio (HR) 1.907, 95% confidence interval (CI) 1.161-3.132, P < 0.001) to be an independent prognostic factor for OS, as were tumor depth, grade and PLR. CONCLUSIONS: Preoperative FAR is associated with tumor progression and can be considered an independent factor for OS of resected STS patients. PMID- 30285657 TI - Chronic active Epstein-Barr virus infection of T-cell type, systemic form in an African migrant: case report and review of the literature on diagnostics standards and therapeutic options. AB - BACKGROUND: Chronic active Epstein-Barr virus (EBV) infection (CAEBV) of the T /NK-cell type, systemic form is a rare and potentially life-threatening illness caused by persistent EBV infection. The highest incidence is found in children and adolescents with increased frequency among Asians and Native Americans, while the disease is uncommon in Western countries. Typically patients present with unspecific symptoms, like fever, lymphadenopathy, hepatosplenomegaly and liver dysfunction. Due to fatal complications including hemophagocytic syndrome, coagulopathy, multiple organ failure and development of EBV-positive lymphoproliferative disease (LPD) or lymphoma early diagnosis is critical for successful treatment. However, in consequence of the lack of experience due to the low incidence in Europe, a broad spectrum of clinical manifestations and a particularly unexpected group of patients, diagnosis can be challenging. Inhere we describe the clinicopathological findings of an African adult with CAEBV associated LPD with a brief review of the literature. CASE PRESENTATION: A 42 year-old African man with fever, enlargement of the spleen and a suspected epileptic seizure was referred to our hospital. Diagnostic testing repeatedly revealed a massive EBV-DNA load in peripheral blood. Whole-body PET-CT-scan presented a strong uptake at multiple bone marrow sites, the thyroid and the adrenal glands. Histopathological analysis of bone marrow and thyroid gland revealed a highly proliferating, atypical and predominantly intravascular cytotoxic T-cell population with intracellular EBV-encoded RNA. Clonality analysis revealed the presence of polyclonal T-cell-receptor. Based on these findings a CAEBV of the T-/NK-cell type, systemic form was diagnosed. Subsequent therapy including three cycles of chemotherapy with cyclophosphamide, doxorubicin, vincristine and prednisolone resulted in decreased EBV load, clinical improvement and ongoing complete remission. CONCLUSION: Adult-onset CAEBV of T/NK-cell type usually comprises a poor prognosis and is extremely rare in Western countries. Therefore, our case highlights the need for a clinical awareness of this disease in patients with systemic illness and for a comprehensive multidisciplinary diagnostic approach to facilitate diagnosis. Treatment options include antiviral drugs, immunosuppressive agents and systemic chemotherapy with or without allogeneic stem cell transplantation. Given the limited data these options need to be decided upon in each patient individually considering severity of the disease, comorbidities and response. PMID- 30285658 TI - Sociocultural determinants of nomadic women's utilization of assisted childbirth in Gossi, Mali: a qualitative study. AB - BACKGROUND: In sub-Saharan Africa (SSA), nomads account for 30 to 60 million people. Their mobility, due to a constant search for pastures and water points, makes health services less accessible to them. Few nomadic women use assisted delivery, which increases the risk of maternal mortality. The reasons behind this limited use have been poorly documented. The objective of this study was to understand the sociocultural determinants of assisted childbirth by nomadic women. METHODS: We conducted a qualitative research in the health area of Gossi (Mali), mainly populated by nomads. Data were collected through a literature review, 26 semi-structured interviews, a non-participant observation, and a logbook. Nomadic women who gave birth in the past three months were included in the study, whether they used assisted delivery or not. A thematic content analysis was performed with QDA Miner software. RESULTS: The study identified a complex combination of determinants resulting in the use or non-use of assisted childbirth by the nomads of Gossi. Several participants recognized the value of assisted delivery but gave birth at home. They identified sociocultural determinants related to their representations and bodily experiences; the risks and emotions (fear, stress, anxiety) associated with pregnancy; the onset of labor and delivery; and their weak autonomy in terms of movement, decision making, and economic agency. Nomadic women are not free in their movements, and in order to seek care, they require the permission and support of a man (husband, brother, or father). Furthermore, the participants are housewives, and men control family resources and make decisions regarding all financial matters. Assisted delivery is often only considered when there are complications. CONCLUSION: This research has made it possible to understand the sociocultural determinants of the use of assisted childbirth among nomadic women, which should be taken into account when organizing health services for these populations. PMID- 30285659 TI - Trends in stroke outcomes in the last ten years in a European tertiary hospital. AB - BACKGROUND: Studying the impact of demographic changes and progress in the management of stroke patients is necessary in order to organize care structures for the coming years. Consequently, we analyzed the prognostic trends of patients admitted to the Stroke Unit of a tertiary hospital in the last ten years. METHODS: The University Clinical Hospital of Santiago de Compostela is the referral hospital for stroke in a catchment area that accounts for 16.5% of the population of Galicia. Data from patients admitted to the Stroke Unit were registered prospectively. A multinomial logistic regression was performed to determine the influence of new trends in demographic factors and in the management of patients with acute stroke. For the expected trend of progression, a 2008-2011 and 2012-2017 time series model was made by selecting the most appropriate model. RESULTS: In the last 10 years, the age of stroke onset has only increased in women (from 74.4 +/- 2.2 years in 2008 to 78.8 +/- 2.1 years in 2017; p = 0.037), and the same happens with the severity of neurological symptoms (ischemic stroke (IS), p < 0.0001; from 14 [10, 19] in 2008 to 19 [15, 26] in 2017), with a higher percentage of cardioembolic strokes (40.7% vs. 32.2% of cardioembolic strokes in women vs. men, p < 0.0001). In a multiple linear regression model, hospital improvement was mainly associated with the use of reperfusion treatment (B 53.11, CI 95% 49.87, 56.36, p < 0.0001). A differentiated multinomial logistic regression analysis conducted for the whole sample with ischemic strokes in the two time periods (2008-2011 and 2012-2017) showed no differences in the influence of factors associated with higher morbidity and mortality. The modeling of time series showed a distinct falling trend in mortality, with a slight increase in good outcome as well as morbidity in both ischemic and hemorrhagic stroke. CONCLUSIONS: Our results showed that mortality decreased in the entire sample; however, although outcome at discharge improved in ischemic stroke, severe disability also increased in these patients. Importantly, this tendency towards increased morbidity seems to be confirmed for the coming years. PMID- 30285660 TI - A multicenter survey on toxoplasmosis knowledge among pregnant women in Poland (the TOWER study). AB - BACKGROUND: The seroprevalence of Toxoplasma gondii ranges widely in different areas of the world and different populations. Although toxoplasmosis is typically benign and asymptomatic, it induces major complications in immunocompromised individuals and during pregnancy. Prevention of maternal primary infection constitutes the major tool for avoiding congenital T. gondii infections and toxoplasmosis complications. The preventive measures depend on the women's knowledge about toxoplasmosis. The aim of the study was to assess the knowledge on toxoplasmosis among pregnant women in Poland. METHODS: The study was conducted between October 2016 and January 2017 in 3 Polish cities. During a visit in a hospital outpatient clinic, pregnant women aged > 16 years fulfilled a previously validated questionnaire. The questions concerned personal data (age, parity, educational level, place of residence), toxoplasmosis knowledge (etiology, routes of transmission, symptoms, sequelae), and sources consulted to collect information. RESULTS: Overall, 465 pregnant women participated in the survey; 439 (94.4%) were aware of toxoplasmosis. Toxoplasmosis was perceived as a zoonotic disease by 77.4%, as a parasitic disease by 41.7%, as a disease transmitted through poor hand hygiene by 8.6%, as a childhood illness by 4%, and as a congenital disease by 0.4%. Regarding the transmission route, 84.5% of women pointed at a domestic cat, 46.7% at eating raw or undercooked meat. The total of 84.3% did not know toxoplasmosis symptoms, and 12.0% stated that they did not present the symptoms. In multivariate analysis, younger age (OR, 2.74; 95% CI, 1.67-4.49; p < 0.001), city residence (OR, 13.45; 95% CI, 3.12-57.89; p < 0.003), and higher education level (OR, 6.81; 95% CI, 3.69-12.59; p < 0.001) were significantly associated with better knowledge of toxoplasmosis, and the number of children (OR, 0.32; 95% CI, 0.22-0.48; p < 0.001) - with higher knowledge of the symptoms. CONCLUSIONS: Among pregnant women in Poland, the basic knowledge on toxoplasmosis is very high (94.4%). Younger age, city residence, higher education level, and the number of children turned out significantly associated with better knowledge of T. gondii and toxoplasmosis symptoms. PMID- 30285661 TI - Short term risk of non-fatal and fatal suicidal behaviours: the predictive validity of the Columbia-Suicide Severity Rating Scale in a Swedish adult psychiatric population with a recent episode of self-harm. AB - BACKGROUND: The Columbia-Suicide Severity Rating Scale (C-SSRS) is a relatively new instrument for the assessment of suicidal ideation and behaviour that is widely used in clinical and research settings. The predictive properties of the C SSRS have mainly been evaluated in young US populations. We wanted to examine the instrument's predictive validity in a Swedish cohort of adults seeking psychiatric emergency services after an episode of self-harm. METHODS: Prospective cohort study of patients (n = 804) presenting for psychiatric emergency assessment after an episode of self-harm with or without suicidal intent. Suicidal ideation and behaviours at baseline were rated with the C-SSRS and subsequent non-fatal and fatal suicide attempts within 6 months were identified by record review. Logistic regression was used to evaluate separate ideation items and total scores as predictors of non-fatal and fatal suicide attempts. Receiver operating characteristics (ROC) curves were constructed for the suicidal ideation (SI) intensity score and the C-SSRS total score. RESULTS: In this cohort, the median age at baseline was 33 years, 67% were women and 68% had made at least one suicide attempt prior to the index attempt. At least one non-fatal or fatal suicide attempt was recorded during follow-up for 165 persons (20.5%). The single C-SSRS items frequency, duration and deterrents were associated with this composite outcome; controllability and reasons were not. In a logistic regression model adjusted for previous history of suicide attempt, SI intensity score was a significant predictor of a non-fatal or fatal suicide attempt (OR 1.08; 95% CI 1.03-1.12). ROC analysis showed that the SI intensity score was somewhat better than chance in correctly classifying the outcome (AUC 0.62, 95% CI 0.57-0.66). The corresponding figures for the C-SSRS total score were 0.65, 95% CI 0.60-0.69. CONCLUSIONS: The C-SSRS items frequency, duration and deterrents were associated with elevated short term risk in this adult psychiatric cohort, as were both the SI intensity score and the C-SSRS total score. However, the ability to correctly predict future suicidal behaviour was limited for both scores. PMID- 30285662 TI - PD-L1/PD-1 crosstalk in colorectal cancer: are we targeting the right cells? AB - BACKGROUND: The analysis of tumour-infiltrating immune cells within patients' tumour samples in colorectal cancer (CRC) has become an independent predictor of patient survival. The tumour microenvironment and the immune checkpoints, such as PD-L1/PD-1, are relevant to the prognoses and also appear to be relevant for further CRC therapies. METHODS: We analysed the presence and features of the infiltrated monocyte/macrophage and lymphocyte populations in both tumour and peritumour samples from patients with CRC (n = 15). RESULTS: We detected a large number of CD14+ monocytes/macrophages with an alternative phenotype (CD64+CD163+) and CD4+ lymphocytes that infiltrated the tumour, but not the peritumour area. The monocytes/macrophages expressed PD-L1, whereas the lymphocytes were PD-1+; however, we did not find high PD-L1 levels in the tumour cells. Coculture of circulating naive human monocytes/macrophages and lymphocytes with tumour cells from patients with proficient mismatch repair CRC induced both an alternative phenotype with higher expression of PD-L1 in CD14+ cells and the T-cell exhaustion phenomenon. The addition of an alpha-PD-1 antibody restored lymphocyte proliferation. CONCLUSION: These results emphasise the interesting nature of immune checkpoint shifting therapies, which have potential clinical applications in the context of colorectal cancer. PMID- 30285663 TI - Neurological signs as early determinants of dementia and predictors of mortality among older adults in Latin America: a 10/66 study using the NEUROEX assessment. AB - BACKGROUND: Neurodegenerative processes in the elderly damage the brain, leading to progressive, incapacitating cognitive, behavioral, and motor dysfunctions which culminate in dementia. Fully manifest dementia is likely to be preceded by the presence of neurological signs, which could serve as early determinants of dementia and predictors of mortality. The aims of this study were to assess the construct validity of a neurological battery assessed among older adults living in Latin America, and to test the association of groups of neurological signs with dementia cross-sectionally, and mortality longitudinally. METHODS: The 10/66 Dementia Research Group collected information on neurological symptoms via the NEUROEX assessment in population based surveys of older adults living in low and middle-income countries. Data from 10,856 adults participating in the baseline assessment of the 10/66 study and living in Cuba, Dominican Republic, Peru, Venezuela and Mexico were analysed. Exploratory and confirmatory analysis were used to explore dimensionality of neurological symptoms. Poisson regression analyses were used to link groups of neurological signs with dementia at baseline. Cox hazard regression models were used to explore the predictive validity of neurological signs with mortality at follow up. RESULTS: Exploratory and confirmatory factor analyses revealed four dimensions of neurological signs, which are associated with lesions of specific brain regions. The identified factors showed consistency with groups of neurological signs such as frontal, cerebellar, extrapyramidal, and more generalized gait disturbance signs. Regression analyses revealed that all groups of neurological signs were positively associated with dementia at baseline and predicted mortality at follow up. CONCLUSIONS: Our findings support the construct and predictive validity of the NEUROEX assessment, linking neurological and gait impairments with dementia at baseline, and with mortality at follow up among older adults living in five Latin American countries. PMID- 30285664 TI - The rs2147578 C > G polymorphism in the Inc-LAMC2-1:1 gene is associated with increased neuroblastoma risk in the Henan children. AB - BACKGROUND: The rs2147578 C > G polymorphism in the long non-coding RNA gene Lnc LAMC2-1:1 is associated with increased susceptibility to a few types of cancers. However, its role in neuroblastoma has not been evaluated yet. METHODS: We investigated the association between the lnc-LAMC2-1:1 rs2147578 C > G polymorphism and neuroblastoma susceptibility in Chinese Han populations. A total of 393 neuroblastoma cases and 812 healthy individuals from the Henan and Guangdong provinces were enrolled and subjected to genotyping. Odds ratio (OR) and 95% confidence interval (CI) were used to determine the strength of the association of interest. RESULTS: Combined analysis revealed that the lnc-LAMC2 1:1 rs2147578 C > G polymorphism was associated with increased neuroblastoma susceptibility (CG vs. CC: adjusted OR = 1.33, 95% CI = 1.01-1.75, P = 0.045; CG/GG vs. CC: adjusted OR = 1.34, 95% CI = 1.03-1.74, P = 0.028). In stratification analysis, children under 18 months with rs2147578 CG/GG genotypes had an increased neuroblastoma risk (adjusted OR = 1.70, 95% CI = 1.08-2.67, P = 0.022). Females with rs2147578 CG/GG genotypes also had increased neuroblastoma susceptibility (adjusted OR = 2.08, 95% CI = 1.37-3.18, P = 0.0007). In addition, children with lnc-LAMC2-1:1 rs2147578 CG/GG genotypes were prone to develop earlier stages of neuroblastoma (adjusted OR = 1.46, 95% CI = 1.01-2.12, P = 0.046). CONCLUSIONS: The Lnc-LAMC2-1:1 rs2147578 C > G polymorphism may contribute to increased neuroblastoma susceptibility in children of Henan province.

PMID- 30285666 TI - Health utility scores of family caregivers for leukemia patients measured by EQ 5D-3L: a cross-sectional survey in China. AB - BACKGROUND: This study assessed the health related quality of life of family caregivers (FCs) of leukemia patients by using the health utility scores derived from the EuroQol five-dimensional (EQ-5D) questionnaire. METHODS: A cross sectional survey was undertaken on 306 family caregivers of leukemia patients to assess their health utility using the EQ-5D-3L. Participants were recruited from three hospitals in China's Heilongjiang province. The health utility scores of the participants were estimated based on the Chinese EQ-5D-3L value set and compared with those of the local general population. Factors predicting the health utility scores were identified through the Kruskal-Wallis analysis of variance and median regression analyses. RESULTS: FCs had lower health utility scores than the general population (p < 0.001). The participants with a lower socioeconomic status had lower utility scores and reported more problems than those with a higher socio-economic status. Better family function and higher social support were associated with higher health utility scores. The type of leukemia, household income, and social support are significant predictors of health utility scores of the FCs. Chronic lymphocytic leukemia, low socio economic status, and low social support are associated with lower health utility scores of the FCs. CONCLUSIONS: FCs for leukemia patients have lower health utility scores than the local general population, as measured by the EQ-5D-3L. There is an immediate need to address the health concerns of FCs, who play an important role in the Chinese health care system. PMID- 30285667 TI - Prevalence and associated factors of pediatric emergency mortality at Tikur Anbessa specialized tertiary hospital: a 5 year retrospective case review study. AB - BACKGROUND: Childhood mortality remains high in resource-limited third world countries. Most childhood deaths in hospital often occur within the first 24 h of admission. Many of these deaths are from preventable causes. This study aims to describe the patterns of mortality in children presenting to the pediatric emergency department. METHODS: This was a five-year chart review of deaths in pediatric patients aged 7 days to 13 years presenting to the Tikur Anbessa Specialized Tertiary Hospital (TASTH) from January 2012 to December 2016. Data were collected using a pretested, structured checklist, and analyzed using the SPSS Version 20. Multivariate analysis by logistic regression was carried out to estimate any measures of association between variables of interest and the primary outcome of death. RESULTS: The proportion of pediatric emergency department (PED) deaths was 4.1% (499 patients) out of 12,240 PED presentations. This translates to a mortality rate of 8.2 deaths per 1000 patients per year. The three top causes of deaths were pneumonia, congestive heart failure (CHF) and sepsis. Thirty two percent of the deaths occurred within 24 h of presentation with 6.5% of the deaths being neonates and the most common co-morbid illness was malnutrition (41.1%). Multivariate analysis revealed that shortness of breath [AOR=2.45, 95% CI (1.22-4.91)], late onset of signs and symptoms [AOR=3.22, 95% CI (1.34-7.73)], fever [AOR=3.17, 95% CI (1.28-7.86)], and diarrhea [AOR=3.36, 95% CI (1.69-6.67)] had significant association with early mortality. CONCLUSION: The incidence of pediatric emergency mortality was high in our study. A delay in presentation of more than 48 hours, diarrheal diseases and shortness of breath were significantly associated with early pediatric mortality. Early identification and intervention are required to reduce pediatric emergency mortality. PMID- 30285668 TI - The prognostic and predictive value of tumor-infiltrating lymphocytes and hematologic parameters in patients with breast cancer. AB - BACKGROUND: Carcinogenesis and tumor growth are associated with chronic inflammation and the host immune system. Here, we investigated the clinical significance and relationship between tumor-infiltrating lymphocytes (TILs) and hematologic parameters in patients with breast cancer. METHODS: Invasive ductal breast cancer patients (N = 145) who underwent surgery were retrospectively evaluated. Samples were obtained using a core needle biopsy for CD8+, FOXP3+ TIL assessment. Blood lymphocytes, neutrophils, monocytes, and platelets were obtained by peripheral venous punctures. RESULTS: CD8 + TILs were significantly associated with absolute lymphocyte count (ALC) and the absolute monocyte count (AMC). Low LMR (ALC/AMC) (cut-off - 5.3, range = 0.73-12.31) was associated with poor overall survival (OS) (p = 0.010), disease-free survival (DFS) (p = 0.005). However, in subgroup analysis, LMR did not have any value as a prognostic factor in HER2-positive breast cancers. TILs had different prognostic impacts across breast cancer subtypes, although they were not statistically significant. The treatment response after NAC tended to improve in breast cancer patients with high FOXP3+ TILs, low NLR (neutrophil count/ALC) (FOXP3 p for trend = 0.006, NLR p for trend = 0.063). CONCLUSIONS: A relevance between TILs and hematologic parameters in breast cancer was demonstrated. The influence of the immune system on breast cancer progression may differ by subtype. PMID- 30285669 TI - Cost analysis of implementing mHealth intervention for maternal, newborn & child health care through community health workers: assessment of ReMIND program in Uttar Pradesh, India. AB - BACKGROUND: The main intervention under ReMiND program consisted of a mobile health application which was used by community health volunteers, called ASHAs, for counselling pregnant women and nursing mothers. This program was implemented in two rural blocks in Uttar Pradesh state of India with an overall aim to increase quality of health care, thereby increasing utilization of maternal & child health services. The aim of the study was to assess annual & unit cost of ReMiND program and its scale up in UP state. METHOD AND MATERIALS: Economic costing was done from the health system and patient's perspectives. All resources used during designing & planning phase i.e., development of application; and implementation of the intervention, were quantified and valued. Capital costs were annualised, after assessing their average number of years for which a product could be used and accounting for its depreciation. Shared or joint costs were apportioned for the time value a resource was utilized under intervention. Annual cost of implementing ReMiND in two blocks of UP along and unit cost per pregnant woman were estimated. Scale-up cost for implementing the intervention in entire state was calculated under two scenarios - first, if no extra human resource were employed; and second, if the state government adopted the same pattern of human resource as employed under this program. RESULTS: The annual cost for rolling out ReMiND in two blocks of district Kaushambi was INR 12.1 million (US $ 191,894). The annualised start-up cost constituted 9% of overall cost while rest of cost was attributed to implementation of the intervention. The health system program costs in ReMiND were estimated to be INR 31.4 (US $ 0.49) per capita per year and INR 1294 (US $ 20.5) per registered women. The per capita incremental cost of scale up of intervention in UP state was estimated to be INR 4.39 (US $ 0.07) when no additional supervisory staffs were added. CONCLUSION: The cost of scale up of ReMiND in Uttar Pradesh is 6% of annual budget for 'reproductive and child health' line item under state budget, and hence appears to be financially sustainable. PMID- 30285670 TI - A case report of isolated distal upper extremity weakness due to cerebral metastasis involving the hand knob area. AB - BACKGROUND: Unilateral weakness of an upper extremity is most frequently caused by traumatic nerve injury or compression neuropathy. In rare cases, lesion of the central nervous system may result in syndromes suggesting peripheral nerve damage by the initial examination. Pseudoperipheral hand palsy is the best known of these, most frequently caused by a small lesion in the contralateral motor cortex of the brain. The 'hand knob' area refers to a circumscribed region in the precentral gyrus of the posterior frontal lobe, the lesion of which leads to isolated weakness of the upper extremity mimicking peripheral nerve damage. The etiology of this rare syndrome is almost exclusively related to an embolic infarction. CASE PRESENTATION: We present the case of a 70-year-old male patient with isolated left sided upper extremity weakness and clumsiness without sensory disturbance suggesting a lesion of the radial nerve. Nerve conduction studies had normal results excluding peripheral nerve damage. Neuroimaging (cranial CT and MRI) detected 3 space occupying lesions, one of them in the right precentral gyrus. An irregularly shaped tumor was found by CT in the left lung with multiple associated lymph node conglomerates. The metastasis from this mucinous tubular adenocarcinoma with solid anaplastic parts to the 'hand knob' area was responsible for the first clinical sign related to the pulmonary malignancy. CONCLUSIONS: Pseudoperipheral palsy of the upper extremity is not necessarily the consequence of an embolic stroke. If nerve conduction studies have normal results, neuroimaging - preferably MRI - should be performed, as lesion in the hand-knob area of the precentral gyrus can also be caused by a malignancy. PMID- 30285671 TI - The improved cure fraction for esophageal cancer in Linzhou city. AB - BACKGROUND: Survival of esophageal cancer in Linzhou was seen to increase over the past few decades and is higher than the average level of China due to the implementation of comprehensive prevention and control measures. In population based studies, relative survival is a common index to approximate disease specific survival. However, the cure fraction maybe great interest to patients and physicians. This study aimed to investigate the cure fraction of esophageal cancer in Linzou city during 2003-2012 with a cure model. METHODS: We carried out a population-based study of 8067 esophageal cancer patients in the Linzhou city during 2003-2012. Flexible parametric cure models were used to estimate cure proportions and median survival times of uncured by year of diagnosed and age. In each model, an interaction between calendar year and age were included. All variables in the model were included both as constant and time-varying effects. RESULTS: The 5-year relative survival rate was increased in every age group from 2003 to 2012. The huge increase in the cure proportion was observed in each age group. At the year of 2011-2012, 79.8%, 58.0%, 123.4% and 162.7% improvements of cure proportion were seen in age group 19-49, 50-59, 60-69 and 70-99 years compared with year of 2003-2004. Meanwhile, survival of 'uncured' patients changed little in all age group. CONCLUSIONS: The improvement of survival in Linzhou city during 2003-2012 was mainly due to an increasing cure proportion. Huge improvement of cure fraction within short period is likely due to the organized screening of esophageal cancer in Linzhou city. PMID- 30285674 TI - The effectiveness of high-intensity CBT and counselling alone and following low intensity CBT: a reanalysis of the 2nd UK National Audit of Psychological Therapies data. AB - BACKGROUND: A previously published article in this journal reported the service effects from 103 services within the UK Improving Access to Psychological Therapies (IAPT) initiative and the comparative effectiveness of CBT and Counselling provision. All patients received High-intensity CBT or High-intensity Counselling, but some also received Low-intensity CBT before being stepped-up to High intensity treatments. The report did not distinguish between patients who received low-intensity CBT before being stepped-up. This article clarifies the basis for collapsing low- and high-intensity interventions by analysing the four treatment conditions separately. METHOD: Data from 33,243 patients included in the second round of the National Audit of Psychological Therapies (NAPT) were re analysed as four separate conditions: High-intensity CBT only (n = 5975); High intensity Counselling only (n = 3003); Low-intensity CBT plus High-intensity CBT (n = 17,620); and Low-intensity CBT plus High-intensity Counselling (n = 6645). Analyses considered levels of pre-post therapy effect sizes (ESs), reliable improvement (RI) and reliable and clinically significant improvement (RCSI). Multilevel modelling was used to model predictors of outcome, namely patient pre post change on PHQ-9 scores at last therapy session. RESULTS: Significant differences obtained on various outcome indices but were so small they carried no clinical significance. Including the four treatment groups in a multilevel model comprising patient intake severity, patient ethnicity and number of sessions attended showed no significant differences between the four treatment groups. Comparisons between the two high-intensity interventions only (N = 8978) indicated Counselling showed more improvement than CBT by 0.3 of a point on PHQ-9 for the mean number of sessions attended. However, this result was moderated by the number of sessions and for 12 or more sessions, the advantage went to CBT. CONCLUSIONS: This re-analysis showed no evidence of clinically meaningful differences between the four treatment conditions using standard indices of patient outcomes. However, a differential advantage to high-intensity Counselling for fewer than average sessions attended and high-intensity CBT for more than average sessions attended has important service implications. The finding of equivalent outcomes between high-intensity CBT and Counselling for more severe patients also has important policy implications. Empirically-informed procedures (e.g., predictive modelling) for assigning patients to interventions need to be considered to improve patient outcomes. PMID- 30285673 TI - Study on safety of laparoscopic total gastrectomy for clinical stage I gastric cancer: the protocol of the CLASS02-01 multicenter randomized controlled clinical trial. AB - BACKGROUND: The safety of laparoscopic total gastrectomy (LTG) for the treatment of gastric cancer remains lack of clinical evidence. The Chinese Laparoscopic Gastrointestinal Surgery Study (CLASS) Group recently launched a multicenter randomized clinical trial (CLASS02-01) to compare the safety of LTG for clinical stage I gastric cancer with the conventional open total gastrectomy (OTG). METHODS: This CLASS02-01 trial is a prospective, multicenter, randomized, controlled, open, and non-inferiority trial. Two hundred patients who met the inclusion criteria and did not accord with the exclusion criteria will be randomly divided into LTG group (n = 100) and OTG group (n = 100). The primary purpose of this study is to evaluate the early operative morbidity and mortality of LTG compared with OTG for clinical stage I gastric adenocarcinoma. The second purpose is to evaluate the recovery course and compare the postoperative hospital stay of the patients enrolled in this study. DISCUSSION: This CLASS02-01 trial is the first prospective randomized two-arm controlled study to determine the safety of LTG compared with OTG. Through this trial, we hope to show that experienced surgeons can safely perform LTG with lymphadenectomy for gastric cancer. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT03007550 . December 30, 2016. PMID- 30285672 TI - A pragmatic randomized controlled trial of group transdiagnostic cognitive behaviour therapy for anxiety disorders in primary care: study protocol. AB - BACKGROUND: Anxiety disorders are the most common mental disorders in community settings, and they are associated with significant psychological distress, functional and social impairment. While cognitive behaviour therapy (CBT) is the most consistently efficacious psychological treatment for anxiety disorders, barriers preclude widespread implementation of CBT in primary care. Transdiagnostic group CBT (tCBT) focuses on cognitive and behavioural processes and intervention strategies common to different anxiety disorders, and could be a promising alternative to conventional CBT. This study aims to examine the effectiveness of a transdiagnostic group CBT for anxiety disorders program as a complement to treatment-as-usual (TAU) in primary mental health care. METHODS/DESIGN: The trial is a multicentre pragmatic randomized controlled trial with a pre-treatment, post-treatment, and follow-up at 4, 8 and 12-months design. Treatment and control groups. a) tCBT (12 weekly 2-h group sessions following a manualized treatment protocol); b) TAU for anxiety disorders. Inclusion criteria comprise meeting DSM-5 criteria for primary Panic Disorder, Agoraphobia, Social Anxiety Disorder and/or Generalized Anxiety Disorder. Patients are recruited in three regions in the province of Quebec, Canada. The primary outcome measures are the self-reported Beck Anxiety Inventory and the clinician-administered Anxiety and Related Disorders Interview Schedule for DSM-5 (ADIS-5); secondary outcome measures include treatment responder status based on the ADIS-5, and self reported instruments for specific anxiety and depression symptoms, quality of life, functioning, and service utilisation. STATISTICAL ANALYSIS: Intention-to treat analysis. A mixed effects regression model will be used to account for between- and within-subject variations in the analysis of the longitudinal effects of the intervention. DISCUSSION: This rigorous evaluation of tCBT in the real world will provide invaluable information to decision makers, health care managers, clinicians and patients regarding the effectiveness of the intervention. Widespread implementation of tCBT protocols in primary care could lead to better effectiveness, efficiency, access and equity for the large number of patients suffering from anxiety disorders that are currently not obtaining evidence-based psychotherapy. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02811458 . PMID- 30285675 TI - Comparative effectiveness of beta-interferons and glatiramer acetate for relapsing-remitting multiple sclerosis: systematic review and network meta analysis of trials including recommended dosages. AB - BACKGROUND: We systematically reviewed the comparative effectiveness of injectable beta-interferons (IFN-beta) and glatiramer acetate (GA) on annualised relapse rate (ARR), progression and discontinuation due to adverse events (AEs) in RRMS, using evidence from within the drugs' recommended dosages. METHODS: We updated prior comprehensive reviews, checked references of included studies, contacted experts in the field, and screened websites for relevant publications to locate randomised trials of IFN-beta and GA with recommended dosages in RRMS populations, compared against placebo or other recommended dosages. Abstracts were screened and assessed for inclusion in duplicate and independently. Studies were appraised using the Cochrane risk of bias tool. Rate ratios for ARR, hazard ratios for time to progression, and risk ratios for discontinuation due to AEs were synthesised in separate models using random effects network meta-analysis. RESULTS: We identified 24 studies reported in 42 publications. Most studies were at high risk of bias in at least one domain. All drugs had a beneficial effect on ARR as compared to placebo, but not compared to each other, and findings were robust to sensitivity analysis. We considered time to progression confirmed at 3 months and confirmed at 6 months in separate models; while both models suggested that the included drugs were effective, findings were not consistent between models. Discontinuation due to AEs did not appear to be different between drugs. CONCLUSIONS: Meta-analyses confirmed that IFN-beta and GA reduce ARR and generally delay progression as defined in these trials, though there was no clear 'winner' across outcomes. Findings are additionally tempered by the high risk of bias across studies, and the use of an impairment/mobility scale to measure disease progression. Future research should consider more relevant measures of disability and, given that most trials have been short-term, consider a longitudinal approach to comparative effectiveness. REVIEW REGISTRATION: PROSPERO CRD42016043278 . PMID- 30285676 TI - Cerebral granulomatosis as a manifestation of Crohn's disease. AB - BACKGROUND: Crohn's disease (CD) is associated with a variety of extra-intestinal manifestations. Most commonly these involve the eye, skin, joints, coagulation system and liver. Cerebral manifestations of CD have been reported to a far lesser extent. The extensive detrimental impact of neurological symptoms on a patient's quality of life makes an early diagnosis and treatment particularly important. In previous case-reports, diagnosis of cerebral manifestations in CD often relied upon magnetic resonance imaging (MRI) and computed tomography (CT) alone. To our knowledge, only one case-report has documented a histologically confirmed case of cerebral lesions associated with CD so far. CASE PRESENTATION: A 39-year-old right-handed woman with a history of CD was referred to our hospital with etiologically unexplained Gadolinium (Gd)-enhancing cortical lesions, triggering epileptic seizures. A CT-scan of the thorax and bronchoalveolar lavage found no signs of sarcoidosis. Lumbar punctures and laboratory testing found no underlying infection or coincidental autoimmune disorders and MRI-scans showed progression of lesion load. Consequently, the patient underwent stereotactic biopsy of a cortical lesion. Histological examination revealed a mixed lympho-histiocytic and tuberculoid granulomatous inflammation surrounding small vessels and no signs for infection. After exclusion of other granulomatous diseases and the typical histological findings we diagnosed a cerebral granulomatosis as a manifestation of CD. The patient was initially started on azathioprine, which had to be switched to corticosteroids and methotrexate because of an azathioprine related pancreatitis. The patient has not suffered any further epileptic seizures to date. CONCLUSION: Cerebral manifestation of CD is a possibly underreported entity that may respond well to immunosuppressive treatment. In contrast to earlier reports of cerebral manifestations in CD, our patient showed no coincident gastrointestinal symptoms indicating an activity of CD during the progression of cortical lesion load, suggesting that similar to other extra-intestinal manifestations in CD, the activity of gastrointestinal symptoms does not necessarily reflect the activity of CD associated cerebral vasculitis. Therefore, diagnosis and therapy of cerebral manifestation may be delayed when focusing on gastrointestinal symptoms alone. PMID- 30285677 TI - Profiling the B/T cell receptor repertoire of lymphocyte derived cell lines. AB - BACKGROUND: Clonal VDJ rearrangement of B/T cell receptors (B/TCRs) occurring during B/T lymphocyte development has been used as a marker to track the clonality of B/T cell populations. METHODS: We systematically profiled the B/T cell receptor repertoire of 936 cancer cell lines across a variety of cancer types as well as 462 Epstein-Barr Virus (EBV) transformed normal B lymphocyte lines using RNA sequencing data. RESULTS: Rearranged B/TCRs were readily detected in cell lines derived from lymphocytes, and subclonality or potential biclonality were found in a number of blood cancer cell lines. Clonal BCR/TCR rearrangements were detected in several blast phase CML lines and unexpectedly, one gastric cancer cell line (KE-97), reflecting a lymphoid origin of these cells. Notably, clonality was highly prevalent in EBV transformed B lymphocytes, suggesting either transformation only occurred in a few B cells or those with a growth advantage dominated the transformed population through clonal evolution. CONCLUSIONS: Our analysis reveals the complexity and heterogeneity of the BCR/TCR rearrangement repertoire and provides a unique insight into the clonality of lymphocyte derived cell lines. PMID- 30285679 TI - Physical Literacy Knowledge Questionnaire: feasibility, validity, and reliability for Canadian children aged 8 to 12 years. AB - BACKGROUND: Physical literacy is defined as the motivation, confidence, physical competence, and knowledge and understanding to engage in physical activity for life. Physical literacy knowledge and understanding encompasses movement (how to move), performance (evaluation of movement), and health and fitness (value of exercise, need for relaxation and sleep, etc.). This paper describes the development and evaluation of a standardized assessment of physical literacy knowledge and understanding for Canadian children in grades 4, 5, and 6. METHODS: Proposed Physical Literacy Knowledge Questionnaire (PLKQ) content was identified through expert consultation and a review of provincial/territorial physical education curricula for grades 4 to 6. Open-ended questions verified language and generated response options. Feasibility was assessed via completion time and error frequency. Item validity assessed scores by age, gender, and teacher ratings of student knowledge. Test-retest reliability was assessed over short (2 day) and long (7-day) intervals. RESULTS: Subsets of 678 children (54% girls, 10.1 +/- 1.0 years of age) completed the feasibility and validity assessments. Response errors (missing or duplicate responses, etc.) were minimal (2% or less) except for one question (7% error) about the use of safety gear during physical activity. A Delphi process among experts in children's physical activity and fitness achieved consensus on the core content and supported an item analysis to finalize item selection. As expected, knowledge scores increased with age (partial eta2 = 0.07) but were not related to gender (p = 0.63). Teacher ratings of children's knowledge of physical activity behaviour (r = 0.13, p = 0.01) and fitness (r = 0.12, p = 0.03), but not movement skill (r = 0.07, p = 0.19) were associated with PLKQ scores. Test-retest reliability for PLKQ score and individual questions was substantial to excellent for 71% of comparisons over a 2 day interval, but lower over a 7-day interval (53% substantial or excellent). Items with low reliability had high or low proportions of correct responses. CONCLUSIONS: This study provides feasibility and validity evidence for the Physical Literacy Knowledge Questionnaire as an assessment of physical literacy knowledge for Canadian children in grades 4, 5, and 6. Completion rates were high and knowledge scores increased with age. Streamlining of the content in accordance with Delphi panel recommendations would further enhance feasibility, but would also focus the content on items with limited reliability. Future studies of alternative item wording and responses are recommended to enhance test retest reliability. PMID- 30285680 TI - Choice architecture modifies fruit and vegetable purchasing in a university campus grocery store: time series modelling of a natural experiment. AB - BACKGROUND: In developed countries, adolescent and young adult diets have been found to be nutritionally poor. The aim of this study was to examine whether a choice architecture intervention, re-arrangement of produce within a grocery store to increase the accessibility of fruit and vegetables, affected purchasing behaviour on a university campus. METHODS: A database of daily sales data from January 2012 to July 2017 was obtained from a campus grocery store. Two changes to the layout were made during this time period. In January 2015, fruit and vegetables were moved from the back of the store, furthest from the entrance, to the aisle closest to the entrance and an entrance-facing display increasing their accessibility. In April 2016, the entrance-facing display of fruit and vegetables was replaced with a chiller cabinet so that fruit and vegetables remained more accessible than during the baseline period, but less accessible than in the period immediately previously. A retrospective interrupted time series analysis using dynamic regression was used to model the data and to examine the effect of the store re-arrangements on purchasing. All analyses were carried out both for sales-by-quantity and for sales-by-money. RESULTS: The first shop re-arrangement which made fruit and vegetables more prominent, increased the percentage of total sales that were fruit and vegetables, when analysed by either items purchased or money spent. The second rearrangement also had a positive effect on the percentage of total sales that were fruit and vegetables compared to baseline, however this was not significant at the 5% level. Over the five year period, the percentage of sales that were fruit and vegetables declined both in terms of items purchased, and money spent. CONCLUSIONS: Increasing accessibility of fruit and vegetables in a grocery store is a feasible way to improve the diet of students in tertiary education. There is evidence of declining fruit and vegetable consumption among the studied population, which should be further investigated. PMID- 30285681 TI - A cross-sectional study exploring the relationship between age, gender, and physical measures with adequacy in and predilection for physical activity. AB - BACKGROUND: Physical literacy is a complex construct influenced by a range of physical, behavioural, affective, and cognitive factors. Researchers are interested in relationships among these constituent factors. The purpose of this study was to investigate how age, gender, and physical competence components of physical literacy relate to a child's adequacy in and predilection for physical activity. METHODS: A sample of 8530 Canadian youth (50% girl) aged 8.0 to 12.9 years participated in the study. Participants completed the Canadian Assessment of Physical Literacy (CAPL) protocol, which assesses physical literacy in four domains: Physical Competence, Daily Behaviour, Motivation and Confidence, and Knowledge and Understanding. Stepwise multiple regression analyses were conducted to investigate the relationship between physical competence components of physical literacy (Progressive Aerobic Cardiovascular Endurance Run [PACER], Canadian Agility and Movement Skill Assessment [CAMSA], sit and reach, handgrip, plank, and body mass index) and children's perceived adequacy and predilection toward physical activity as measured by subscales from the Children's Self Perceptions of Adequacy in and Predilection for Physical Activity scale (CSAPPA). RESULTS: The variable most strongly associated with adequacy and predilection was the PACER shuttle run score. The PACER accounted for 10.9% of the variance in adequacy and 9.9% of the variance in predilection. Participants' age was inversely related to adequacy (beta = - 0.374) and predilection (beta = - 0.621). The combination of other variables related to adequacy brought the total variance explained to 14.7%, while the model for predilection explained a total of 13.7%. CONCLUSIONS: Results indicate an association between cardiorespiratory fitness and measures of physical activity adequacy and predilection. These findings suggest that practitioners should consider the physiological and psychological makeup of the child, and ways to enhance adequacy and predilection among children with limited cardiorespiratory fitness, in order to create the best possible environment for all children to participate in physical activity. PMID- 30285678 TI - N-cadherin in cancer metastasis, its emerging role in haematological malignancies and potential as a therapeutic target in cancer. AB - In many types of solid tumours, the aberrant expression of the cell adhesion molecule N-cadherin is a hallmark of epithelial-to-mesenchymal transition, resulting in the acquisition of an aggressive tumour phenotype. This transition endows tumour cells with the capacity to escape from the confines of the primary tumour and metastasise to secondary sites. In this review, we will discuss how N cadherin actively promotes the metastatic behaviour of tumour cells, including its involvement in critical signalling pathways which mediate these events. In addition, we will explore the emerging role of N-cadherin in haematological malignancies, including bone marrow homing and microenvironmental protection to anti-cancer agents. Finally, we will discuss the evidence that N-cadherin may be a viable therapeutic target to inhibit cancer metastasis and increase tumour cell sensitivity to existing anti-cancer therapies. PMID- 30285682 TI - Refining the Canadian Assessment of Physical Literacy based on theory and factor analyses. AB - BACKGROUND: The Canadian Assessment of Physical Literacy (CAPL) is a 25-indicator assessment tool comprising four domains of physical literacy: (1) Physical Competence, (2) Daily Behaviour, (3) Motivation and Confidence, and (4) Knowledge and Understanding. The purpose of this study was to re-examine the factor structure of CAPL scores and the relative weight of each domain for an overall physical literacy factor. Our goal was to maximize content representation, and reduce construct irrelevant variance and participant burden, to inform the development of CAPL-2 (a revised, shorter, and theoretically stronger version of CAPL). METHODS: Canadian children (n = 10,034; Mage = 10.6, SD = 1.2; 50.1% girls) completed CAPL testing at one time point. Confirmatory factor analysis was used. RESULTS: Based on weak factor loadings (lambdas < 0.32) and conceptual alignment, we removed body mass index, waist circumference, sit-and-reach flexibility, and grip strength as indicators of Physical Competence. Based on the factor loading (lambda < 0.35) and conceptual alignment, we removed screen time as an indicator of Daily Behaviour. To reduce redundancy, we removed children's activity compared to other children as an indicator of Motivation and Confidence. Based on low factor loadings (lambdas < 0.35) and conceptual alignment, we removed knowledge of screen time guidelines, what it means to be healthy, how to improve fitness, activity preferences, and physical activity safety gear indicators from the Knowledge and Understanding domain. The final refined CAPL model was comprised of 14 indicators, and the four-factor correlated model fit the data well (r ranged from 0.08 to 0.76), albeit with an unexpected cross loading from Daily Behaviour to knowledge of physical activity guidelines (mean- and variance-adjusted weighted least square [WLSMV] chi2(70) = 1221.29, p < 0.001, Comparative Fit Index [CFI] = 0.947, root mean square error of approximation [RMSEA] = 0.041[0.039, 0.043]). Finally, our higher-order model with Physical Literacy as a factor with indicators of Physical Competence (lambda = 0.68), Daily Behaviour (lambda = 0.91), Motivation and Confidence (lambda = 0.80), and Knowledge and Understanding (lambda = 0.21) fit the data well. CONCLUSIONS: The scores from the revised and much shorter 14-indicator model of CAPL can be used to assess the four correlated domains of physical literacy and/or a higher-order aggregate physical literacy factor. The results of this investigation will inform the development of CAPL-2. PMID- 30285683 TI - Postoperative function recovery in patients with endoprosthetic knee replacement for bone tumour: an observational study. AB - BACKGROUND: The objective of this study is to describe the rehabilitative pathway of patients undergoing endoprosthetic knee replacement surgery, build reference values of the functional results achieved, and identify possible prognostic factors. METHODS: Prospective observational study. All patients undergoing resection and knee replacement surgery using a modular prosthesis following bone tumor resection were consecutively recruited over the last 2 years. The patients were followed for a period of 1 year, the result values were collected at 3, 6 and 12 months. RESULTS: In total, 30 patients were enrolled. The median age was 19 years with 33% of patients being female. Median values recorded for knee flexion, quadriceps strength, Toronto Extremity Salvage Score, Time Up and Go and Six Minutes Walking Test showed an improvement of 16, 25, 18, 48 and 38% from 3 to 12 months, respectively. The level and width of the resection were correlated with the mobility of the knee and the strength of the quadriceps. CONCLUSION: Patients undergoing knee replacement for bone tumors were able to achieve satisfactory functional outcomes from the first postoperative year. A specific assessment of outcomes can be conducted to facilitate the management of patient expectations. A very wide resection and interventions of the proximal tibia are risk factors for a poorer functional outcome. PMID- 30285684 TI - Challenges of achieving sustainable community health services for community case management of malaria. AB - BACKGROUND: Community Case Management of malaria (CCMm) using Community Health Workers (CHWs) is an approach to improve access to timely and effective malaria case management in malaria endemic countries. So far the programme has been shown to be effective in many communities in sub-Saharan Africa. However, questions remain on the sustainability of this programme due to the high dropout cases of CHWs given their modest remuneration. The aim of the study was to identify challenges of achieving sustainable community health services for CCMm. METHODS: A community based qualitative study was conducted in five districts in western Kenya where CCMm was being undertaken. In-depth interviews and focus group discussions were conducted with the CHWs, mothers of children under-five years and key informants such as public health officers and clinicians involved in the CCMm. The interviews were audio recorded and conducted in English, Swahili and the local language. Recorded interviews were transcribed. Analysis was conducted using NVivo version 7 software, where transcripts were coded after which themes related to the objectives of the study were identified. RESULTS: The community members, the CHWs and stakeholders perceived CCMm as an important approach for reducing the burden of malaria. Key informants perceived lack of basic supplies (RDTs, gloves), drugs, inadequate remuneration of CHWs and lack of basic working equipment as challenges for CCM. CHWs highlighted that lack of drugs and basic supplies such as gloves at the health facilities, inadequate community sensitization by health workers, inadequate stipend to meet basic needs, as challenges of achieving sustainable CCMm. Some clinicians perceived that CHWs should not be given Artemisinin-based combination therapy (ACT) as part of the CCMm since they might misuse them. CONCLUSION: This study shows that for CCMm to be sustainable, concerted efforts from stakeholders are needed to boost the programme. Commodities needed for implementation of the programme need to be readily available and the morale of the CHWs who undertake CCMm needs boosting. PMID- 30285686 TI - Alcohol audio-visual content in formula 1 television broadcasting. AB - BACKGROUND: Exposure to audio-visual alcohol content in media is associated with subsequent alcohol use among young people. In 2016 Heineken launched its global Formula One (F1) partnership and had a significant brand presence at a number of 2017 F1 race events. We have measured the extent to which Heineken and other alcohol content appears in a sample of the first 6 races broadcast in the UK during the 2017 F1 Championship. METHODS: We used 1-min interval coding to quantify alcohol content in all broadcast footage, including advertisement breaks. RESULTS: Alcohol content occurred in all of the races shown and in 41% of all advertisement breaks in the programming. The most prominent content was alcohol branding, occurring in 39% of race footage intervals. Alcohol branding consisted mostly of billboard advertisements or branding on the side of cars or racing suits with Heineken and Johnnie Walker being most prominent. Alcohol branding was shown in race footage from countries where alcohol promotion is prohibited. All of the race footage was broadcast on Channel 4 on a Sunday, with start times ranging from 12:35 to 18:45. CONCLUSION: Audio-visual alcohol content, including branding, was highly prevalent footage of 2017 F1 races broadcast during peak viewing times in the UK. This content is likely to be a significant driver of alcohol consumption among children and adolescents. PMID- 30285685 TI - Cafeteria assessment for elementary schools (CAFES): development, reliability testing, and predictive validity analysis. AB - BACKGROUND: Strategies to reduce childhood obesity and improve nutrition include creating school food environments that promote healthy eating. Despite well documented health benefits of fruit and vegetable (FV) consumption, many U.S. school-aged children, especially low-income youth, fail to meet national dietary guidelines for FV intake. The Cafeteria Assessment for Elementary Schools (CAFES) was developed to quantify physical attributes of elementary school cafeteria environments associated with students' selection and consumption of FV. CAFES procedures require observation of the cafeteria environment where preparation, serving, and eating occur; staff interviews; photography; and scoring. METHODS: CAFES development included three phases. First, assessment items were identified via a literature review, expert panel review, and pilot testing. Second, reliability testing included calculating inter-item correlations, internal consistency (Kuder-Richardson-21 coefficients), and inter-rater reliability (percent agreement) based on data collected from 50 elementary schools in low income communities and 3187 National School Lunch Program participants in four U.S. states. At least 43% of each participating school's students qualified for free- or reduced-price meals. Third, FV servings and consumption data, obtained from lunch tray photography, and multi-level modeling were used to assess the predictive validity of CAFES. RESULTS: CAFES' 198 items (grouped into 108 questions) capture four environmental scales: room (50 points), table/display (133 points), plate (4 points), and food (11 points). Internal consistency (KR 21) was 0.88 (overall), 0.80 (room), 0.72 (table), 0.83 (plate), and 0.58 (food). Room subscales include ambient environment, appearance, windows, layout/visibility, healthy signage, and kitchen/serving area. Table subscales include furniture, availability, display layout/presentation, serving method, and variety. Inter-rater reliability (percent agreement) of the final CAFES tool was 90%. Predictive validity analyses indicated that the total CAFES and four measurement scale scores were significantly associated with percentage consumed of FV served (p < .05). CONCLUSIONS: CAFES offers a practical and low-cost measurement tool for school staff, design and public health practitioners, and researchers to identify critical areas for intervention; suggest low- and no-cost intervention strategies; and contribute to guidelines for cafeteria design, food presentation and layout, and operations aimed at promoting healthy eating among elementary school students. PMID- 30285687 TI - Canadian Assessment of Physical Literacy Second Edition: a streamlined assessment of the capacity for physical activity among children 8 to 12 years of age. AB - BACKGROUND: The Canadian Assessment of Physical Literacy (CAPL) assesses the capacity of children to lead a physically active lifestyle. It is comprised of a battery of standardized assessment protocols that reflect the Canadian consensus definition of physical literacy. The Royal Bank of Canada Learn to Play - Canadian Assessment of Physical Literacy study implemented the CAPL with 10,034 Canadian children (50.1% female), 8 to 12 years of age. Feedback during data collection, necessary changes identified by the coordinating centre, and recent data analyses suggested that a streamlined, second edition of the CAPL was required. The purpose of this paper is to describe the methods used to develop the CAPL second edition (CAPL-2). METHODS: The larger dataset created through the RBC-Learn to Play CAPL study enabled the re-examination of the CAPL model through factor analyses specific to Canadian children 8 to 12 years of age from across Canada. This comprehensive database was also used to examine the CAPL protocols for redundancy or variables that did not contribute significantly to the overall assessment. Removing redundancy had been identified as a priority in order to reduce the high examiner and participant burden. The "lessons learned" from such a large national surveillance project were reviewed for additional information regarding the changes that would be required to optimize the assessment of children's physical literacy. In addition, administrative changes, improvements, and corrections were identified as necessary to improve the quality and accuracy of the CAPL manual and training materials. RESULTS: For each domain of the CAPL, recommended changes based on the factor analyses, qualitative feedback and theoretical considerations significantly reduced the number of protocols. Specific protocol combinations were then evaluated for model fit within the overarching concept of physical literacy. The CAPL-2 continues to reflect the four components of the Canadian consensus definition of physical literacy: Motivation and Confidence, Physical Competence, Knowledge and Understanding, and engagement in Physical Activity Behaviour. The CAPL-2 is comprised of three Physical Competence protocols (plank, Progressive Aerobic Cardiovascular Endurance Run [PACER], Canadian Agility and Movement Skill Assessment [CAMSA]), two Daily Behaviour protocol (pedometer steps, self-reported physical activity), and a 22-item questionnaire assessing the physical literacy domains of Motivation and Confidence, and Knowledge and Understanding. Detailed information about the CAPL-2 is available online ( www.capl-eclp.ca ). CONCLUSIONS: The CAPL-2 dramatically reduces examiner and participant burden (three Physical Competence protocols, two Daily Behaviour protocols, and a 22-response questionnaire; versus eight Physical Competence protocols, three Daily Behaviour protocols and a 72 response questionnaire for the original CAPL), while continuing to be a comprehensive assessment of all aspects of children's physical literacy using the Canadian consensus definition of this term. Like the original, the CAPL-2 continues to offer maximum flexibility to practitioners, who can choose to complete the entire CAPL-2 assessment, only one or more domains, or select individual protocols. Regardless of the assessment selected, scores are available to interpret the performance of each child relative to Canadian children of the same age and sex. All of the protocols included in the CAPL-2 have published reports of validity and reliability for this age group (8 to 12 years). The detailed manual for CAPL-2 administration, along with training materials and other resources, are available free of charge on the CAPL-2 website ( www.capl eclp.ca ). All CAPL-2 materials and resources, including the website, are available in both English and French. PMID- 30285688 TI - Associations between domains of physical literacy by weight status in 8- to 12 year-old Canadian children. AB - BACKGROUND: The Canadian Assessment of Physical Literacy (CAPL) is divided into four domains (Physical Competence, Daily Behaviour, Motivation and Confidence, and Knowledge and Understanding) and provides a robust and comprehensive assessment of physical literacy. As weight status is known to influence health related behaviours such as physical fitness and activity, it is important to investigate whether the associations between the domains of physical literacy vary among children of different weight status. The aim of this study was to determine the associations among the four domains of physical literacy stratified by weight status. METHODS: Canadian children aged 8 to 12 years (n = 8343, 63.6% healthy-weight) completed the CAPL. Differences in domain scores and overall physical literacy score by weight status (children of healthy weight versus children with overweight/obese) were assessed using MANOVA (multivariate analysis of variance). Partial correlations between the four domains were calculated, adjusting for gender and age, and correlation coefficients of both weight status groups were compared using the Steiger test. RESULTS: For all four domains as well as overall physical literacy, healthy-weight children had higher scores than their overweight/obese peers (Cohen's d ranged from 0.05 to 0.44). Weak to moderate correlations were found between all of the domains for both groups. Correlation coefficients for Physical Competence and Daily Behaviour as well as for Physical Competence and Knowledge and Understanding were generally stronger in the healthy-weight children (r = 0.29 and 0.22, respectively) compared with the overweight/obese children (r = 0.23 and 0.17, respectively). CONCLUSIONS: All of the domains of the CAPL correlate positively with each other regardless of weight status, with a trend for these correlation coefficients to be slightly stronger in the healthy-weight children. The overall weak to moderate correlations between the domains in both groups suggest that the CAPL domains are not measuring the same constructs, thus providing support for CAPL's psychometric architecture in both healthy-weight and overweight/obese children. PMID- 30285689 TI - Public awareness and individual responsibility needed for judicious use of antibiotics: a qualitative study of public beliefs and perceptions. AB - BACKGROUND: High consumption of antibiotics has been identified as an important driver for the increasing antibiotic resistance, considered to be one of the greatest threats to public health globally. Simply informing the public about this consequence is insufficient to induce behavioral change. This study explored beliefs and perceptions among Swedes, with the aim of identifying factors promoting and hindering a judicious approach to antibiotics use. The study focused primarily on the medical use of antibiotics, also considering other aspects connected with antibiotic resistance, such as travelling and food consumption. METHODS: Data were collected through focus group discussions at the end of 2016. Twenty-three Swedes were recruited using an area-based approach and purposive sampling, aiming for as heterogeneous groups as possible regarding gender (13 women, 10 men), age (range 20-81, mean 38), and education level. Interview transcripts were analyzed using qualitative content analysis. The Health Belief Model was used as a theoretical framework. RESULTS: Antibiotic resistance was identified by participants as a health threat with the potential for terrible consequences. The severity of the problem was perceived more strongly than the actual likelihood of being affected by it. Metaphors such as climate change were abundantly employed to describe antibiotic resistance as a slowly emerging problem. There was a tension between individual (egoistic) and collective (altruistic) reasons for engaging in judicious behavior. The individual effort needed and antibiotics overprescribing were considered major barriers to such behavior. In their discussions, participants stressed the need for empowerment, achieved through good health communication from authorities and family physicians. CONCLUSIONS: Knowledge about antibiotic consumption and resistance, as well as values such as altruism and trust in the health care system, has significant influence on both perceptions of individual responsibility and on behavior. This suggests that these factors should be emphasized in health education and health promotion. To instead frame antibiotic resistance as a slowly emerging disaster, risks diminish the public perception of being susceptible to it. PMID- 30285690 TI - Associations between teacher training and measures of physical literacy among Canadian 8- to 12-year-old students. AB - BACKGROUND: Quality physical education (PE) contributes to the development of physical literacy among children, yet little is known about how teacher training relates to this development. We assessed the association between teacher training, and the likelihood that children met recommended achievement levels for components of physical literacy as defined by the Canadian Assessment of Physical Literacy (CAPL). METHODS: Canadian children (n = 4189; M = 10.72 years, SD = 1.19) from six provinces completed the CAPL. Logistic regression was used to examine the relationship between teacher training (generalist/PE specialist), adjusting for children's age and gender, and physical competence protocols (sit and reach, handgrip, plank, Progressive Aerobic Cardiovascular Endurance Run [PACER], body mass index [BMI], waist circumference, Canadian Agility and Movement Skill Assessment [CAMSA]), the four CAPL domain scores, and the total CAPL score. RESULTS: Teacher training, in addition to children's age and gender, explained only a very small proportion of variance in each model (all R2 < 0.03). Children taught by a generalist were less likely to reach recommended levels of motivation and confidence (OR = 0.83, 95% CI, 0.72-0.95) or CAMSA scores (OR = 0.77, 95% CI, 0.67-0.90), even when accounting for a significant increase in CAMSA score with age (OR = 1.18, 95% CI, 1.12-1.26). All other associations between measures of components of physical literacy and teacher training were not significant. CONCLUSIONS: While teacher training is hypothesized to contribute to the development of physical literacy among elementary school students, the observed effects in this study were either small or null. Children taught by PE specialists were more likely than those taught by generalists to demonstrate recommended levels of motivation and confidence, and to have better movement skills, which are hypothesized to be critical prerequisites for the development of a healthy lifestyle. Further research with more robust designs is merited to understand the impact of teachers' training on the various components of physical literacy development. PMID- 30285691 TI - Lymph node ratio is inferior to pN-stage in predicting outcome in colon cancer patients with high numbers of analyzed lymph nodes. AB - BACKGROUND: The lymph node ratio (LNR), i.e. the number of positive lymph nodes (LN) divided by the total number of analyzed LN, has been described as a strong outcome predictor in node-positive colon cancer patients. However, most published analyses are constrained by relatively low numbers of analyzed LN. Therefore, the objective of the present study was to evaluate the prognostic impact of LNR in colon cancer patients with high numbers of analyzed LN. METHODS: One hundred sixty-six colon cancer patients underwent open colon resection. All node-positive patients were analyzed for this study. The number of analyzed LN, of positive LN, the disease-free (DFS) and overall survival (OS) time were prospectively recorded. Patients were dichotomously allocated to a high or a low LNR-group, respectively, with the median LNR (0.125) as a cut-off value. Median follow-up was 34.3 months. RESULTS: Fifty-eight patients (34.9%) were node-positive. The median number of analyzed LN was 23 (range 8-54). DFS and OS were significantly shorter in pN2 vs pN1 patients (p < 0.001, and p = 0.001, respectively), and in LNR high vs low patients (p = 0.032, and p = 0.034, respectively). pN2 (vs pN1) disease showed hazard ratios (HR) of 6.2 (p < 0.001), and 6.8 (p < 0.005; for DFS and OS, respectively), while LNR high (vs low) showed HR of 3.0 (p =0.041), and 4.5 (p = 0.054). CONCLUSIONS: LNR is a reasonable outcome predictor in node positive colon cancer patients. However, LNR is inferior to pN-stage in predicting survival in patients with high number of harvested lymph nodes. PMID- 30285692 TI - Infection after knee replacement: a qualitative study of impact of periprosthetic knee infection. AB - BACKGROUND: Approximately 340,000 knee replacements are performed each year in the USA and UK. Around 1% of patients who have had knee replacement develop deep infection around the prosthesis: periprosthetic knee infection. Treatment often requires a combination of one or more major operations and antibiotic therapy. This study aimed to understand and characterise patients' experiences of periprosthetic knee infection. METHODS: Qualitative semi-structured interviews were conducted with 16 patients (9 men, 7 women; 59-80 years, mean age 72) who experienced periprosthetic knee infection and subsequent revision treatment in six National Health Service orthopaedic departments. Interviews were audio recorded, transcribed, anonymised and analysed thematically. The concept of biographical disruption was used to frame our analysis, and four transcripts double-coded for rigour. Patients were interviewed between two and 10 months after surgical revision. RESULTS: Participant experiences can be characterised according to three aspects of biographical disruption which we have used to frame our analysis: onset and the problem of recognition; emerging disability and the problem of uncertainty, and chronic illness and the mobilisation of resources. Participants' experiences of infection and treatment varied, but everyone who took part reported that infection and revision treatment had devastating effects on them. Participants described use of social and healthcare support and a need for more support. Some participants thought that the symptoms that they had first presented with had not been taken seriously enough. CONCLUSIONS: Periprosthetic knee infection and its treatment can be life-changing for patients, and there is a need for greater support throughout treatment and lengthy recovery. Future work could look at preparedness for adverse outcomes, help-seeking in impactful situations, and information for healthcare professionals about early signs and care for periprosthetic infection. PMID- 30285693 TI - Physical literacy levels of Canadian children aged 8-12 years: descriptive and normative results from the RBC Learn to Play-CAPL project. AB - BACKGROUND: The current physical literacy level of Canadian children is unknown. The Royal Bank of Canada (RBC) Learn to Play - Canadian Assessment of Physical Literacy (CAPL) project, which is anchored in the Canadian consensus statement definition of physical literacy, aimed to help establish the current physical literacy level of Canadian children. METHODS: The CAPL was used to assess the physical literacy (and component domains: Daily Behaviour, Physical Competence, Knowledge and Understanding, and Motivation and Confidence) of Canadian children aged 8-12 years. Data were collected from 11 sites across Canada, yielding a sample of 10,034 participants (5030 girls). Descriptive statistics by age and gender were calculated and percentile distributions of physical literacy scores, including each domain and individual measure, were derived. RESULTS: The mean age of participants was 10.1 +/- 1.2 years. Total physical literacy scores (out of 100) were on average 63.1 +/- 13.0 for boys and 62.2 +/- 11.3 for girls. For boys and girls respectively, domain scores were 19.9 +/- 4.7 and 19.3 +/- 4.1 (out of 32) for Physical Competence; 18.6 +/- 7.9 and 18.5 +/- 7.4 (out of 32) for Daily Behaviour; 12.7 +/- 2.8 and 12.2 +/- 2.6 (out of 18) for Motivation and Confidence; and 11.8 +/- 2.8 and 12.2 +/- 2.6 (out of 18) for Knowledge and Understanding. Physical Competence measures were on average 28.1 +/- 8.4 cm (sit and-reach flexibility), 33.5 +/- 9.4 kg (grip strength, right + left), 23.4 +/- 14.1 laps (Progressive Aerobic Cardiovascular Endurance Run [PACER] shuttle run), 61.8 +/- 43.8 s (isometric plank), 19.0 +/- 3.8 kg/m2 (body mass index), 67.3 +/- 10.8 cm (waist circumference), and 20.6 +/- 3.9 out of 28 points for the Canadian Agility and Movement Skill Assessment (CAMSA), with scores for boys higher than girls and older children higher than younger children for grip strength, PACER, plank, and CAMSA score. Girls and younger children had better scores on the sit and-reach flexibility than boys and older children. Daily pedometer step counts were higher in boys than girls (12,355 +/- 4252 vs. 10,779 +/- 3624), and decreased with age. CONCLUSIONS: These results provide the largest and most comprehensive assessment of physical literacy of Canadian children to date, providing a "state of the nation" baseline, and can be used to monitor changes and inform intervention strategies going forward. PMID- 30285695 TI - Oxygen versus air-driven nebulisers for exacerbations of chronic obstructive pulmonary disease: a randomised controlled trial. AB - BACKGROUND: In exacerbations of chronic obstructive pulmonary disease, administration of high concentrations of oxygen may cause hypercapnia and increase mortality compared with oxygen titrated, if required, to achieve an oxygen saturation of 88-92%. Optimally titrated oxygen regimens require two components: titrated supplemental oxygen to achieve the target oxygen saturation and, if required, bronchodilators delivered by air-driven nebulisation. The effect of repeated air vs oxygen-driven bronchodilator nebulisation in acute exacerbations of chronic obstructive pulmonary disease is unknown. We aimed to compare the effects of air versus oxygen-driven bronchodilator nebulisation on arterial carbon dioxide tension in exacerbations of chronic obstructive pulmonary disease. METHODS: A parallel group double-blind randomised controlled trial in 90 hospital in-patients with an acute exacerbation of COPD. Participants were randomised to receive two 2.5 mg salbutamol nebulisers, both driven by air or oxygen at 8 L/min, each delivered over 15 min with a 5 min interval in-between. The primary outcome measure was the transcutaneous partial pressure of carbon dioxide at the end of the second nebulisation (35 min). The primary analysis used a mixed linear model with fixed effects of the baseline PtCO2, time, the randomised intervention, and a time by intervention interaction term; to estimate the difference between randomised treatments at 35 min. Analysis was by intention to-treat. RESULTS: Oxygen-driven nebulisation was terminated in one participant after 27 min when the PtCO2 rose by > 10 mmHg, a predefined safety criterion. The mean (standard deviation) change in PtCO2 at 35 min was 3.4 (1.9) mmHg and 0.1 (1.4) mmHg in the oxygen and air groups respectively, difference (95% confidence interval) 3.3 mmHg (2.7 to 3.9), p < 0.001. The proportion of patients with a PtCO2 change >=4 mmHg during the intervention was 18/45 (40%) and 0/44 (0%) for oxygen and air groups respectively. CONCLUSIONS: Oxygen-driven nebulisation leads to an increase in PtCO2 in exacerbations of COPD. We propose that air-driven bronchodilator nebulisation is preferable to oxygen-driven nebulisation in exacerbations of COPD.

PMID- 30285694 TI - Cardiorespiratory fitness is associated with physical literacy in a large sample of Canadian children aged 8 to 12 years. AB - BACKGROUND: The associations between cardiorespiratory fitness (CRF) and physical literacy in children are largely unknown. The aim of this study was to assess the relationships between CRF, measured using the 20-m shuttle run test (20mSRT), and components of physical literacy among Canadian children aged 8-12 years. METHODS: A total of 9393 (49.9% girls) children, with a mean (SD) age of 10.1 (+/-1.2) years, from a cross-sectional surveillance study were included for this analysis. The SRT was evaluated using a standardized 15 m or 20 m protocol. All 15 m SRTs were converted to 20mSRT values using a standardized formula. The four domains of physical literacy (Physical Competence, Daily Behaviour, Motivation and Confidence, and Knowledge and Understanding) were measured using the Canadian Assessment of Physical Literacy. Tertiles were identified for 20mSRT laps, representing low, medium, and high CRF for each age and gender group. Cohen's d was used to calculate the effect size between the low and high CRF groups. RESULTS: CRF was strongly and favourably associated with all components of physical literacy among school-aged Canadian children. The effect size between low and high CRF tertile groups was large for the Physical Competence domain (Cohen's d range: 1.11-1.94) across age and gender groups, followed by moderate to large effect sizes for Motivation and Confidence (Cohen's d range: 0.54-1.18), small to moderate effect sizes for Daily Behaviour (Cohen's d range: 0.25-0.81), and marginal to moderate effect sizes for Knowledge and Understanding (Cohen's d range: 0.08-0.70). CONCLUSIONS: This study identified strong favourable associations between CRF and physical literacy and its constituent components in children aged 8-12 years. Future research should investigate the sensitivity and specificity of the 20mSRT in screening those with low physical literacy levels. PMID- 30285697 TI - Nationwide surveillance algorithms for tuberculosis among immigrant workers from highly endemic countries following pre-entry screening in Taiwan. AB - BACKGROUND: This cross-sectional study was retrospectively performed to assess the trend of tuberculosis (TB) among Taiwan's immigrant workers from highly TB endemic countries under an intervention of conducting a 4-round follow-up (at 0-3 days and 6, 18, and 30 months post-migration) screening program with initial chest X-ray (CXR) following an overseas, pre-entry normal CXR. METHODS: The immigrant workers with TB disease enrolled in the Taiwan TB registry database in 2011-2014 were analyzed and linked to an immigrant worker physical exam database to stratify TB case categories of actively screened or not for comparison. RESULTS: Following pre-entry screening for the admission of CXR-normal immigrant workers from highly endemic countries, the overall TB incidence of 70.6 128.6/100,000 person-years resulted either from a subsequent series of 4-round post-entry active screenings or misalliance algorithms, including passive diagnostics for the illness. Overall, the TB relative risk based on incidence in the immigrant working population was 2.2- to 5.5-fold greater than that among corresponding age Taiwanese, with 14.3% (15.5/100,000 person-years) sputum-smear positive pulmonary TB (SS+ PTB), 74.2% (80.8/100,000 person-years) sputum-smear negative (SS-) PTB, and 7.8% (8.5/100,000 person-years) only extra-pulmonary TB (EPTB). Regarding the clinical characteristics, 55.5% TB cases - identified through passive illness diagnostics vs. 44.5% TB cases actively identified through mandatory screenings, were higher in SS+ PTB (adjusted odds Ratio (aOR): 1.5, 95% CI: 1.1-2.0, P = 0.008), higher in SC+ PTB (aOR: 1.4, 95% CI: 1.1-1.7, P = 0.004), higher in concurrent extra-pulmonary TB (aOR: 8.9, CI: 4.5-7.4, P < 0.001), and higher in normal CXR TB (aOR: > 100, CI: 0- > 100, P = 0.908). The TB yields of 3rd- to 4th-round screenings were higher than those of 1st- and 2nd round screenings and ranged from 52.6-65.3 cases per 100,000 screenings in 2013 2014. CONCLUSIONS: The multiple post-entry TB screenings with initial CXR for high-risk immigrants could actively reduce TB transmission by finding SS- TB cases at early stages. The TB yields at post-entry 3rd- to 4th-round screenings might imply a persistent reactivation of latent TB. Adding more sensitive, economical screenings and preventive treatments for latent TB infection is a comprehensive approach for accelerating TB elimination. PMID- 30285699 TI - Factors associated with late presentation of cervical cancer cases at a district hospital: a retrospective study. AB - BACKGROUND: Cervical cancer is the leading and most common female cancer among women in Ghana. Although there are screening methods to detect premalignant lesions for treatment, screening coverage in Ghana is 2.8% and late presentation of cases complicates treatment efforts. This study examined the sociodemographic, clinical and histological characteristics associated with late presentation of cervical cancer cases attending Gynecological Oncology care at Catholic Hospital, Battor. METHODS: One hundred and fifty-seven medical records of confirmed cases of cervical cancer reporting to the Outpatient Obstetrics and Gynecology Department between 2012 and 2016 were reviewed. Relevant data were retrieved using abstraction forms. Socio demographic variables investigated were level of education attained, marital status, National Health Insurance Scheme membership, employment status, place of residence and distance from hospital. Clinical variables included intermenstrual/postmenopausal bleeding, previous screening history, previous smoking history, age at menarche and number of children. Histological variables included subtypes of tumour and characteristics of tumour. Pearson's chi-square test and logistic regression analysis were used to determine correlates of late stage at presentation with cervical cancer. Sensitivity analysis was performed to assess the effect of missing data. RESULTS: Approximately two-thirds (65.97%) of the cases presented in advanced stages of cervical cancer. Level of education, age at menarche and previous screening history were included in a regression model and adjusted for age. Age at menarche (n = 66) was eliminated from the model after sensitivity analysis. Among the remaining variables, only previous screening history was predictive of late stage at presentation of cervical cancer cases. Previously unscreened cases of cervical cancer were nearly four times more likely to present late, compared to those who had been screened previously (OR 3.91; 95% CI 1.43-10.69). No association was observed with sociodemographic and histological characteristics. CONCLUSION: Lack of previous screening was associated with late presentation of cervical cancer at Catholic Hospital, Battor. Efforts to promote early cervical cancer screening should be intensified and future studies may explore an association with age at menarche. PMID- 30285700 TI - CRISPR/Cas9-mediated genome editing induces gene knockdown by altering the pre mRNA splicing in mice. AB - BACKGROUND: Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR associated protein 9 (CRISPR/Cas9) has been wildly used to generate gene knockout models through inducing indels causing frame-shift. However, there are few studies concerning the post-transcript effects caused by CRISPR-mediated genome editing. RESULTS: In the present study, we showed that gene knockdown model also could be generated using CRISPR-mediated gene editing by disrupting the boundary of exon and intron in mice (C57BL/6 J). CRISPR induced indel at the boundary of exon and intron (5' splice site) caused alternative splicing and produced multiple different mRNAs, most of these mRNAs introduced premature termination codon causing down expression of the gene. CONCLUSIONS: These results showed that alternative splicing mutants were able to generate through CRISPR-mediated genome editing by deleting the boundary of exon and intron causing disruption of 5' splice site. Although alternative splicing was an unexpected outcome, this finding could be developed as a technology to generate gene knockdown models or to investigate pre-mRNA splicing. PMID- 30285698 TI - Identification of key genes involved in the phenotypic alterations of res (restored cell structure by salinity) tomato mutant and its recovery induced by salt stress through transcriptomic analysis. AB - BACKGROUND: The res (restored cell structure by salinity) mutant, recently identified as the first tomato mutant accumulating jasmonate in roots under non stressful conditions, exhibits a remarkable growth inhibition and morphological alterations in roots and leaves, which are suppressed when the mutant plants are exposed to salinity. In order to understand the molecular basis of the phenotype recovery induced by salt stress in the res mutant, we carried out a comparative transcriptomic analysis in roots and leaves of wild-type and res plants in absence of stress (control) and when the phenotypic recovery of res mutant began to be observed upon salt stress (5 days of 200 mM NaCl). RESULTS: The number of differentially expressed genes was three times greater in roots than in leaves of res vs WT plants grown in control, and included the down-regulation of growth promoting genes and the up-regulation of genes involved in Ca2+ signalling, transcription factors and others related to stress responses. However, these expression differences were attenuated under salt stress, coinciding with the phenotypic normalisation of the mutant. Contrarily to the attenuated response observed in roots, an enhanced response was found in leaves under salt stress. This included drastic expression changes in several circadian clock genes, such as GIGANTEA1, which was down-regulated in res vs WT plants. Moreover, the higher photosynthetic efficiency of res leaves under salt stress was accompanied by specific salt-upregulation of the genes RUBISCO ACTIVASE1 and ALTERNATIVE OXIDASE1A. Very few genes were found to be differentially expressed in both tissues (root and leaf) and conditions (control and salt), but this group included SlWRKY39 and SlMYB14 transcription factors, as well as genes related to protein homeostasis, especially protease inhibitors such as METALLOCARBOXYPEPTIDASE INHIBITOR, which also seem to play a role in the phenotype recovery and salt tolerance of res mutant. CONCLUSIONS: In summary, in this study we have identified genes which seem to have a prominent role in salt tolerance. Moreover, we think this work could contribute to future breeding of tomato crops with increased stress tolerance. PMID- 30285701 TI - Canada's Physical Literacy Consensus Statement: process and outcome. AB - BACKGROUND: Healthy movement behaviours of Canadian children and youth have been found to be suboptimal; this is associated with declines in physical fitness, increases in obesity, and elevated chronic disease risk. Physical literacy is an evolving construct representing foundational domains upon which physically active lifestyles are based. Many sectors and organizations in Canada are embracing physical literacy in their programs, practices, policies, and research; however, the use of inconsistent definitions and conceptualizations of physical literacy had been identified by stakeholders as hindering promotion and advancement efforts. METHODS: With leadership from ParticipACTION, organizations from the physical activity, public health, sport, physical education, and recreation sectors collaborated to create a physical literacy consensus definition and position statement for use by all Canadian organizations and individuals. The process involved an environmental scan, survey of related evidence, stakeholder consultations, and creation of a Steering Committee. From this background work a consensus statement was drafted, shared with stakeholders, revised, and ratified. RESULTS: Canada's Physical Literacy Consensus Statement was launched in June 2015 at the International Physical Literacy Conference in Vancouver, British Columbia. To further promote the Consensus Statement, the Sport for Life Society developed and simultaneously released the "Vancouver Declaration", which contained additional guidance on physical literacy. Both the Consensus Statement and the Declaration endorsed the International Physical Literacy Association's definition of physical literacy, namely "the motivation, confidence, physical competence, knowledge and understanding to value and take responsibility for engagement in physical activities for life". CONCLUSIONS: Sector partners hope that the Consensus Statement, with its standardized definition, brings greater harmony, synergy, and consistency to physical literacy efforts in Canada and internationally. Going forward, the impact of this initiative on the sector, and the more distal goal of increasing habitual physical activity levels, should be assessed. PMID- 30285702 TI - A systematic review of compliance with indoor tanning legislation. AB - BACKGROUND: Many jurisdictions have enacted indoor tanning legislation in response to the health risks of artificial ultraviolet (UV) radiation exposure. Key components of these legislations include banning minors' access, requiring parental consent or accompaniment, providing protective eyewear, posting health warning signs, and communicating important health risk information. However, legislation must be complied with to be impactful. Evidence around compliance with indoor tanning legislations has not been synthesized and is an important step toward determining changes in practice due to legislation. METHODS: A systematic review was conducted to obtain peer-reviewed literature about compliance with indoor tanning legislation worldwide. Six databases were searched, resulting in 12,398 citations. Sixteen studies met the inclusion criteria (peer-reviewed scientific studies, published in English, focused primarily on compliance with indoor tanning legislations, and focused on commercial indoor tanning in indoor tanning facilities). RESULTS: Compliance with most aspects of indoor tanning legislation varied widely. There was good compliance for provision of protective eyewear (84 to 100%; mean = 92%; SD = 8). Compliance with age restrictions ranged from 0 to 100% (mean = 65%; SD = 25), while compliance with posting warning labels in the required locations within a tanning facility ranged from 8 to 72% (mean = 44%; SD = 27). Variation in compliance may be due to true differences, study methodology, or temporal trends. CONCLUSIONS: Variability in compliance with indoor tanning legislation, as found in this systematic review, indicates the legislations may not be having their intended protective effects on the public's health. The reasons for such low and varied compliance with certain aspects of legislation, and high compliance with other aspects of legislation, deserve further attention in future research to inform best practices around ensuring high and consistent compliance with indoor tanning legislations worldwide. PMID- 30285703 TI - The relationship between sedentary behaviour and physical literacy in Canadian children: a cross-sectional analysis from the RBC-CAPL Learn to Play study. AB - BACKGROUND: Physical literacy is the foundation of a physically active lifestyle. Sedentary behaviour displays deleterious associations with important health indicators in children. However, the association between sedentary behaviour and physical literacy is unknown. The purpose of this study was to identify the aspects of physical literacy that are associated with key modes of sedentary behaviour among Canadian children participating in the RBC-CAPL Learn to Play study. METHODS: A total of 8,307 children aged 8.0-12.9 years were included in the present analysis. Physical literacy was assessed using the Canadian Assessment of Physical Literacy, which measures four domains (Physical Competence, Daily Behaviour, Motivation and Confidence, Knowledge and Understanding). Screen-based sedentary behaviours (TV viewing, computer and video game use), non-screen sedentary behaviours (reading, doing homework, sitting and talking to friends, drawing, etc.) and total sedentary behaviour were assessed via self-report questionnaire. Linear regression models were used to determine significant (p<0.05) correlates of each mode of sedentary behaviour. RESULTS: In comparison to girls, boys reported more screen time (2.7+/-2.0 vs 2.2+/-1.8 hours/day, Cohen's d=0.29), and total sedentary behaviour (4.3+/-2.6 vs 3.9+/-2.4 hours/day, Cohen's d=0.19), but lower non-screen-based sedentary behaviour (1.6+/ 1.3 vs 1.7+/-1.3 hours/day, Cohen's d=0.08) (all p< 0.05). Physical Competence (standardized beta's: -0.100 to -0.036, all p<0.05) and Motivation and Confidence (standardized beta's: -0.274 to -0.083, all p<0.05) were negatively associated with all modes of sedentary behaviour in fully adjusted models. Knowledge and Understanding was negatively associated with screen-based modes of sedentary behaviour (standardized beta's: -0.039 to -0.032, all p<0.05), and positively associated with non-screen sedentary behaviour (standardized beta: 0.098, p<0.05). Progressive Aerobic Cardiovascular Endurance Run score and log transformed plank score were negatively associated with all screen-based modes of sedentary behaviour, while the Canadian Agility and Movement Skill Assessment score was negatively associated with all modes of sedentary behaviour other than TV viewing (all p<0.05). CONCLUSIONS: These results highlight differences in the ways that screen and non-screen sedentary behaviours relate to physical literacy. Public health interventions should continue to target screen-based sedentary behaviours, given their potentially harmful associations with important aspects of physical literacy. PMID- 30285704 TI - A Lanosteryl triterpene from Protorhus longifolia augments insulin signaling in type 1 diabetic rats. AB - BACKGROUND: A substantial literature supports antidiabetic properties of the lanosteryl triterpene (methyl-3beta-hydroxylanosta-9,24-dien-21-oate, RA-3) isolated from Protorhus longifolia stem bark. However, the molecular mechanism(s) associated with the antihyperglycemic properties of the triterpene remained to be explored. The current study aimed at investigating the molecular mechanism(s) through which RA-3 improves insulin signaling in streptozotocin-induced type 1 diabetic rats. METHODS: The type 1 diabetic rats were treated daily with a single oral dose of RA-3 (100 mg/kg) for 28 days. The rats were then sacrificed, and blood, skeletal muscle and pancreases were collected for biochemical, protein expression and histological analysis, respectively. RESULTS: Persistently high blood glucose levels in the diabetic control rats significantly increased expression of IRS-1Ser307 while the expression of p-Akt Ser473, p-GSK-3beta Ser9, GLUT 4 and GLUT 2 were decreased. However, enhanced muscle insulin sensitivity, which was indicated by a decrease in the expression of IRS-1ser307 with a concomitant increase in the p-AktSer473, p-GSK-3beta Ser9, GLUT 4 and GLUT 2 expression were observed in the diabetic rats treated with RA-3. The triterpene treated animals also showed an improved pancreatic beta-cells morphology, along with increased C-peptide levels. An increase in the levels of serum antioxidants such as catalase, superoxide dismutase, and reduced glutathione was noted in the rats treated with the triterpene, while their serum levels of interleukin-6 and malondialdehyde were reduced. CONCLUSIONS: It is apparent that RA-3 is able to improve the insulin signaling in type 1 diabetic rats. Its beta (beta)-cells protecting mechanism could be attributed to its ability to alleviate inflammation and oxidative stress in the cells. PMID- 30285705 TI - A high burden of asymptomatic genital tract infections undermines the syndromic management approach among adolescents and young adults in South Africa: implications for HIV prevention efforts. AB - BACKGROUND: Youth in southern Africa, particularly adolescent girls and young women, are a key population for HIV prevention interventions. Untreated genital tract infections (GTIs) increase both HIV transmission and acquisition risks. South African GTI treatment guidelines employ syndromic management, which relies on individuals to report GTI signs and symptoms. Syndromic management may, however, underestimate cases, particularly among youth. We compared genital tract infection (GTI) prevalence by symptom-based and laboratory assessment among sexually-experienced youth in South Africa, overall and stratified by sex. METHODS: Interviewer-administered surveys assessed socio-demographics, behaviors, and GTI symptoms among 352 youth (16-24 yrs., HIV-negative or unknown HIV status at enrollment) enrolled in community-based cohorts in Durban and Soweto (2014 2016). Laboratory tests assessed HIV, Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG), Trichomonas vaginalis (TV) infections and, among females, bacterial vaginosis (BV) and Candida species. Youth with genital ulcers were tested for HSV-2 and syphilis. We assessed sensitivity (and specificity) of symptom-based reporting in identifying laboratory-confirmed GTIs. RESULTS: At baseline, 16.2% of females (32/198) and < 1% (1/154) of males reported >=1 GTI symptom. However, laboratory tests identified >=1 GTI in 70.2% and 10.4%, respectively. Female CT prevalence was 18.2%, NG 7.1%, MG 9.6%, TV 8.1%, and 5.1% were newly diagnosed with HIV. BV prevalence was 53.0% and candidiasis 9.6%. One female case of herpes was identified (0 syphilis). Male CT prevalence was 7.8%, NG 1.3%, MG 3.3%, TV < 1%, and 2.0% were newly diagnosed with HIV. Overall, 77.8% of females and 100% of males with laboratory-diagnosed GTIs reported no symptoms or were asymptomatic. Sensitivity (and specificity) of symptom-based reporting was 14% (97%) among females and 0% (99%) among males. CONCLUSION: A high prevalence of asymptomatic GTIs and very poor sensitivity of symptom-based reporting undermines the applicability of syndromic GTI management, thus compromising GTI control and HIV prevention efforts among youth. Syndromic GTI management does not meet the sexual health needs of young people. Policy changes incorporating innovations in GTI diagnostic testing are needed to reduce GTIs and HIV-associated risks among youth. PMID- 30285707 TI - The relationship between the abundance of the Nigeria-Cameroon chimpanzee (Pan troglodytes ellioti) and its habitat: a conservation concern in Mbam-Djerem National Park, Cameroon. AB - BACKGROUND: Understanding the relationship between great apes and their habitat is essential for the development of successful conservation strategies. The chimpanzee Pan troglodytes ellioti is endemic to Nigeria and Cameroon, and occupies an ecologically diverse range of habitats from forests to forest savannah mosaic in Mbam-Djerem National Park (MDNP) in Cameroon. The habitat variation in chimpanzees is poorly understood in MDNP which provides an excellent opportunity to assess ecological factors that shape the abundance and distribution patterns of P. t. ellioti over a small geographic scale. RESULTS: We counted 249 nests along 132 km of transects in total. Of these, 119 nests along 68 km occurred in dense forest and 130 nests along 64 km in forest-savannah mosaic. Chimpanzee density was 0.88 [95% CI (0.55-1.41)] individuals/km2 in the dense forest and 0.59 [95% CI (0.19-1.76)] in the forest-savannah mosaic. Nest abundance varied with vegetation type and was higher in areas with dense canopy cover, steeper slopes and relatively higher altitudes. CONCLUSIONS: Our estimates of chimpanzee densities were lower than reported in other studied populations in the range of the Nigeria-Cameroon chimpanzee. However, we found that habitat features, slope and altitude likely play a role in shaping patterns of chimpanzee nesting ecology. Further studies need to be focused on nest decay rates and phenology of useful plants in order to model chimpanzee abundance and distribution in Mbam-Djerem National Park. PMID- 30285708 TI - Bridging the gap to effective feedback in residency training: perceptions of trainees and teachers. AB - BACKGROUND: Clinical feedback is an important part of residency training, yet literature suggests this complex interaction is not completely understood. In particular, little is known about what resident versus attending physicians expect as feedback. This study investigates this gap in knowledge by examining differences in interactions that residents and attendings view as feedback. METHODS: Surveys containing sample clinical feedback scenarios were distributed to residents and attending physicians in emergency medicine and general surgery at a large academic medical center. Respondents were asked to decide whether useful feedback was provided in each scenario, and responses were compared between the two groups. Continuous features were summarized with medians, interquartile ranges (IQRs), and ranges; categorical features were summarized with frequency counts and percentages. Comparisons of features between residents and attendings were evaluated using Wilcoxon rank sum, chi-square, and Fisher exact tests. Statistical analyses were performed using version 9.4 of the SAS software package (SAS Institute, Inc.; Cary, NC). All tests were two-sided and p values < 0.05 were considered statistically significant. RESULTS: Seventy-two individuals responded to the survey out of approximately 110 invitations sent (65%), including 35 (49%) residents and 37 (51%) attendings. Of 35 residents, 31 indicated their level of training, which included 13 (42%) PGY-1, 9 (29%) PGY-2, 6 (19%) PGY-3, and 3 (10%) PGY-4, respectively. Of 37 attendings, 34 indicated the number of years since completion of residency or last fellowship, at a median of 9 years (IQR 4-14; range 1-31). No significant difference was found in residents' and attendings' perceptions of what constituted feedback in the sample scenarios. CONCLUSIONS: While this study did not find a statistical difference in perception of feedback between residents and attendings, additional factors should be considered when investigating perceived feedback deficiencies. Further research is needed to better understand and improve the clinical feedback process. PMID- 30285706 TI - Factors mediating the impacts of child abuse and intimate partner violence on chronic pain: a cross-sectional study. AB - BACKGROUND: Most research on the health impacts of intimate partner violence (IPV) and child abuse has been conducted in Western countries and may not be generalizable to women living in different contexts, such as Saudi Arabia. Chronic pain, a disabling health issue associated with experiences of both child abuse and IPV among women, negatively impacts women's well-being, quality of life, and level of functioning. Yet, the psychosocial mechanisms that explain how abuse relates to chronic pain are poorly understood. We developed and tested a theoretical model that explains how both IPV and child abuse are related to chronic pain. METHODS: We recruited a convenience sample of 299 Saudi women, who had experienced IPV in the past 12 months, from nine primary health care centers in Saudi Arabia between June and August 2015. Women completed a structured interview comprised of self-report measures of IPV, child abuse, PTSD, depressive symptoms, chronic pain, and social support. Using Structural equation modeling (SEM), we analyzed the proposed model twice with different mental health indicators as mediators: PTSD symptoms (Model 1) and depressive symptoms (Model 2). RESULTS: Both models were found to fit the data, accounting for 31.6% (Model 1) and 32.4% (Model 2) of the variance in chronic pain severity. In both models, mental health problems (PTSD and depressive symptoms) fully mediated the relationship between severity of IPV and child abuse and chronic pain severity. Perceived family support partially mediated the relationship between abuse severity and depressive symptoms. CONCLUSIONS: These results underscore the significance of considering lifetime abuse, women's mental health (depressive and PTSD symptoms) and their social resources in chronic pain management and treatment. PMID- 30285709 TI - Study protocol: evaluation of specialized outpatient palliative care in the German state of Hesse (ELSAH study) - work package I: assessing the quality of care. AB - BACKGROUND: In Germany, patients suffering from life-limiting conditions are eligible for specialized outpatient palliative care (SOPC). Evaluation of the quality of this service lacks currently integration of patient-relevant outcomes. There is also no scientific consensus how to prove quality of care in the special context of SOPC adequately. Existing quality reports are primarily based on descriptive structural data which do not allow for estimation of process quality or result quality. The ELSAH study ('Evaluation of Specialized Outpatient Palliative Care in the German state of Hesse') aims to choose - or, if necessary, to adopt - to evaluate and to implement a suit of measures to assess, evaluate and monitor the quality of specialized, home-based palliative care. METHODS: All 22 SOPC teams providing their services in the state of Hesse, Germany, participate in the ELSAH study. The study is divided in two phases: a preparation phase and a main study phase. Based on the findings of the preparation phase we have chosen a preliminary set of instruments including the Integrated Palliative Outcome Scale, Views on Care, Zarit Burden Interview, Phase of Illness, Goal Attainment Scaling, Eastern Cooperative Oncology Group Performance Status, Consumer Quality Indices Palliative Care and Sense of Security in Care. During the main study phase, we will use a mixed-methods approach to evaluate the instruments' psychometric properties (reliability, validity, feasibility and practicability), to identify barriers, facilitators and limitations of their routine use and to explore how their use affects the care within the SOPC setting. DISCUSSION: At the end of this study, an outcome- and patient-centered, validated measurement approach should be provided, adapted for standardized evaluations in SOPC across patient groups, palliative care services and regions nationwide. The standardized application of instruments should allow for making valid statements and comparisons of health care quality in SOPC based on process- and outcome-evaluation rather than relying on structural data only. Moreover, the instruments might directly influence the care of patients in palliative situations. TRIAL REGISTRATION: German Clinical Trials Register (DRKS-ID: DRKS00012421 ). PMID- 30285711 TI - Switching from glargine+insulin aspart to glargine+insulin aspart 30 before breakfast combined with exercise after dinner and dividing meals for the treatment of type 2 diabetes patients with poor glucose control - a prospective cohort study. AB - BACKGROUND: This study aimed to examine the switch from glargine+once daily insulin aspart (1 + 1 regimen) to glargine+insulin aspart 30 before breakfast combined with exercise and in patients with type 2 diabetes mellitus (T2DM) with poorly controlled blood glucose levels. METHODS: Consecutive patients with poorly controlled T2DM (n = 182) were switched from the 1 + 1 regimen to glargine+insulin aspart 30 before breakfast in combination with exercise after dinner and dividing meals in two (same final calories intake). The insulin doses were adjusted according to blood glucose levels within 4 weeks after the switch and maintained for 12 weeks. Fasting blood glucose (FBG), 2-hpostprandial glucose (2hPG), glycosylated hemoglobin (HbA1c), body mass index (BMI), daily insulin dose, and hypoglycemia events were assessed. RESULTS: Sixteen weeks after the switch, 2 h PG levels and HbA1c levels (from 8.5 to 7.4%, P = 0.001) were improved. The proportions of patients reaching the HbA1c targets of 7.5% were improved (from 22.5 to 58.7%, P = 0.001). Among the 182 patients, 24 (13.2%) divided one meal into two meals, and 23 (12.6%) divided two meals into four meals. Among all patients, 8.5% had to reuse insulin aspart before dinner after the study. One patient with diarrhea and poor appetite experienced severe hypoglycemia. The rate of hypoglycemia was 3.76 events/patient-year. The daily insulin Aspart 30 dose was higher than the original insulin aspart dose (P = 0.001). CONCLUSIONS: For patients with poorly controlled T2DM under the 1 + 1 regimen, switching to glargine+insulin aspart 30 before breakfast combined with exercise after dinner and dividing meals showed promising benefits. PMID- 30285710 TI - In vitro pro-inflammatory enzyme inhibition and anti-oxidant potential of selected Sri Lankan medicinal plants. AB - BACKGROUND: The extracts of the ten selected Sri Lankan medicinal plants have been traditionally used in the treatment of inflammatory mediated diseases. The extracts were investigated for anti-inflammatory and anti-oxidant potential in vitro to identify bio-active extracts for further chemical characterization. METHODS: In vitro anti-inflammatory activities of total ethanol extracts were investigated measuring the inhibitory activities of four pro-inflammatory enzymes, arachidonate-5- lipoxygenase (A5-LOX), hyaluronidase (HYL), xanthine oxidase (XO) and inducible nitric oxide (iNO) synthase. Cytotoxicity of extracts were determined by MTT assay. Oxidative burst inhibition (OBI) on human whole blood (WB) and isolated polymorphoneutrophils (PMNs) was carried out for a selected bio-active extract. Anti- oxidant activities of the extracts were determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, ferric reducing antioxidant power (FRAP), ferrous ion chelation (FIC) and oxygen radical absorbance capacity (ORAC) assays. Total polyphenol and total Flavonoid contents of the extracts were also determined. The most active plant extract was analysed using Gas chromatography-Mass spectrometry (GC-MS) and High Performance Liquid Chromatography (HPLC). RESULTS: The ethanol bark extract of Flacourtia indica showed the highest A5-LOX (IC50: 22.75 +/- 1.94 g/mL), XO (70.46 +/- 0.18%; 250 MUg/mL) and iNOs inhibitory activities on LPS- activated raw 264.7 macrophage cells (38.07 +/- 0.93%; 500 MUg/mL) with promising OBI both on WB (IC50: 47.64 2.32 MUg/mL) and PMNs (IC50: 5.02 0.38 MUg/mL). The highest HYL inhibitory activity was showed by the leaf extracts of Barathranthus nodiflorus (42.31 +/- 2.00%; 500 MUg/mL) and Diospyros ebenum (41.60 +/- 1.18%; 500 MUg/mL). The bark and leaf extracts of Callophyllum innophyllum (IC50: 6.99 +/- 0.02 MUg/mL) and Symplocus cochinchinesis (IC50: 9.85 +/- 0.28 MUg/mL) showed promising DPPH free radical scavenging activities. The GC-MS analysis of ethanol bark extract of F. indica showed the presence of two major bio-active compounds linoleic acid ethyl ester and hexadecanoic acid, ethyl ester (> 2% peak area). The HPLC analysis showed the presence polyphenolic compounds. CONCLUSION: The ethanol bark extract of F. indica can be identified as a potential candidate for the development of anti-inflammatory agents, which deserves further investigations. The bio-active plant extracts may be effectively used in the applications of cosmetic and health care industry. PMID- 30285712 TI - Listen to the outpatient: qualitative explanatory study on medical students' recognition of outpatients' narratives in combined ambulatory clerkship and peer role-play. AB - BACKGROUND: Understanding patients' narratives has been associated with methods of improving care that go beyond what may be regarded as a "narrow" view of scientific medicine. Medical interview training in which medical students develop understanding of the importance of patients' narratives is receiving increased attention. However, students generally receive education on patients' narratives that does not distinguish inpatients and outpatients. No studies exploring the characteristics of outpatients' narratives have been reported. We developed an educational program combining ambulatory clerkship and peer role-play using actual narratives from outpatients that students had encountered during their clerkship. These narratives were used as peer role-play scenarios in which the students acted as outpatients. This study explored what and how medical students learned about the characteristics of outpatients' narratives through this original educational program. METHODS: Participants were 70 fifth-year medical students from Nagoya University, Japan. We conducted 13 focus groups, based on a convenience sample of 11 groups in 2012, one group in 2013, and one group in 2017 (from 17 clinical groups in each year). Focus group transcripts were analyzed using the "Steps for Coding and Theorization" qualitative data analysis method. We assessed medical anthropological findings regarding narratives in a conceptual framework. RESULTS: Patients' narratives as perceived by medical students were divided into four quadrants by two axes: medical versus lived content, and objective versus subjective structure. Students recognized that outpatients' narratives mainly used a subjective structure, but were mixed and crossed each quadrant. This was described as "irreproducibility." Students also recognized that narratives of simulated patients and inpatients were mainly limited to a medical-lived content with an objective structure. These differences in narrative characteristics were recognized through students' previous interactions with simulated patients and inpatients. CONCLUSIONS: Despite some limitations, medical students learn about patients' narratives in our original educational program in a way that would be difficult to achieve through training using simulated patients or inpatients. PMID- 30285713 TI - A comprehensive study of the potential phytomedicinal use and toxicity of invasive Tithonia species in South Africa. AB - BACKGROUND: Tithonia diversifolia and T. rotundifolia belong to the Asteraceae family and are native to Mexico and Central America. These plants have become invasive in parts of tropical Africa and Asia where they have become an ecological, agricultural and economic burden. Tithonia diversifolia is exploited by locals in its native and most parts of its invasive range as a source of medicines; however, T. rotundifolia is only used for medicinal purposes in one country in the native range (Venezuela) and none in the invasive range. Although T. diversifolia has been studied for different biological activities, little or no attention has been given to T. rotundifolia. This study compared the antimicrobial activity, phytochemistry, identification of bioactive compound(s) and toxicity levels of different leaf extracts and fractions of T. diversifolia and T. rotundifolia. METHODS: Antimicrobial activity was evaluated against seven pathogenic bacteria, four non-pathogenic Mycobacterium species and three fungal species using serial microdilution assays. Phytochemical contents were determined through standard methods of analysis. UPLC/MS was used to analyse the fractions to identify possible bioactive compounds that may be responsible for bioactivity, while toxicity tests were carried out using the colorimetric MTT assay and the Ames test. RESULTS: Both species had a range of antimicrobial activity against bacterial, mycobacterial and fungal species. However, T. rotundifolia displayed better activity against most of the strains tested with minimum inhibitory concentration values ranging between 0.01 and 0.07 mg/ml. Both species were rich in phenolics, flavonoids and tannins. Tagitinin A was identified as the main compound present in both species, and this compound may be responsible for the antimicrobial activity displayed. Toxicity tests showed that T. diversifolia was cytotoxic at concentrations used in this study, while T. rotundifolia was not. Both species did not show any mutagenic/genotoxic effects. CONCLUSION: The above results suggest that both species may be further developed as a source of antimicrobials for the treatment of infections caused by opportunistic pathogens. They may also serve as alternatives to highly exploited plant species with the same medicinal properties. However, T. diversifolia should be used with caution as it may be toxic. PMID- 30285715 TI - Effect of an audience on trainee stress and performance during simulated neonatal intubation: a randomized crossover trial. AB - BACKGROUND: Neonatal intubation is a stressful procedure taught to trainees. This procedure can attract additional observers. The impact of observers on neonatal intubation performance by trainees has not been studied. Our objective was to evaluate if additional observers present during neonatal mannequin endotracheal intubation (NMEI) by junior trainees, affects their performance and their stress levels. METHODS: A randomized cross over trial was conducted. First year residents with no experience in neonatal intubation were assigned to NMEI condition A or B randomly on day 1. Subjects were crossed over to the other condition on day 2. Condition A: Only one audience member was present Condition B: Presence of an audience of 5 health care providers. Differences in the time to successful NMEI was recorded and compared between conditions. A portable heart rate monitor was used to measure peak heart rate above baseline during NMEI under both conditions. RESULTS: Forty nine residents were recruited. 72% were female with a median age of 25 years (IQR: 24-27). Time to successful intubation was comparable under both conditions with a mean difference of - 3.94 s (95% CI: 8.2,0.4). Peak heart rate was significantly lower under condition A (mean difference - 11.9 beats/min, 95% CI -15.98 to - 7.78). CONCLUSION: Although the time required to NMEI did not increase, our results suggest that presence of observers significantly increases trainee stress. The addition of extraneous observers during simulation training may better equip residents to deal with such stressors. TRIAL REGISTRATION: Date of registration: March 2016, NCT 02726724 . PMID- 30285714 TI - Protective effects and mechanisms of Terminalia catappa L. methenolic extract on hydrogen-peroxide-induced oxidative stress in human skin fibroblasts. AB - BACKGROUND: Oxidative stress plays a crucial role in aging-related phenomenon, including skin aging and photoaging. This study investigated the protective role and possible mechanism of Terminalia catappa L. methanolic extract (TCE) in human fibroblasts (Hs68) against hydrogen peroxide (H2O2)-induced oxidative damage. METHODS: Various in vitro antioxidant assays were performed in this study. The effect and mechanisms of TCE on oxidative stress-induced oxidative damage were studied by using western blotting. RESULTS: The IC50 of TCE was 8.2 MUg/mL for 1,1-diphenyl-2-picrylhydrazyl radical scavenging, 20.7 MUg/mL for superoxide anion radical scavenging, 173.0 MUg/mL for H2O2 scavenging, 44.8 MUg/mL for hydroxyl radical scavenging, and 427.6 MUg/mL for ferrous chelation activities. Moreover, TCE inhibited the H2O2-induced mitogen-activated protein kinase signaling pathway, resulting in the inhibition of c-Jun, c-Fos, matrix metalloproteinase (MMP)-1, MMP-3, MMP-9, and cyclooxygenase-2 expression. TCE also increased hemeoxygenase-1 expression inhibited by H2O2. Finally, TCE was demonstrated reverse type I procollagen expression in fibroblasts after H2O2 treatment. CONCLUSIONS: According to our findings, TCE is a potent antioxidant and protective agent that can be used in antioxidative stress-induced skin aging. PMID- 30285716 TI - The associations between staffing hours and quality of care indicators in long term care. AB - BACKGROUND: Long-term care (LTC) staffing practices are poorly understood as is their influence on quality of care. We examined the relationship between staffing characteristics and residents' quality of care indicators at the unit level in LTC homes. METHODS: This cross-sectional study collected data from administrative records and resident assessments from July 2014 to June 2015 at 11 LTC homes in Ontario, Canada comprising of 55 units and 32 residents in each unit. The sample included 69 registered nurses, 183 licensed/registered practical nurses, 858 nursing assistants, and 2173 residents. Practice sensitive, risk-adjusted quality indicators were described individually, then combined to create a quality of care composite ranking per unit. A multilevel regression model was used to estimate the association between staffing characteristics and quality of care composite ranking scores. RESULTS: Nursing assistants provided the majority of direct care hours in LTC homes (76.5%). The delivery of nursing assistant care hours per resident per day was significantly associated with higher quality of resident care (p = < 0.01). There were small but significant associations with quality of care for nursing assistants with seven or more years of experience (p = 0.02), nursing assistants late to shift (p = < 0.01) and licensed/registered practical nurses late to shift (p = 0.02). CONCLUSIONS: The number of care hours per resident per day delivered by NAs is an important contributor to residents' quality of care in LTC homes. These findings can inform hiring and retention strategies for NAs in LTC, as well as examine opportunities to optimize the NA role in these settings. PMID- 30285717 TI - Quantifying suitable late summer brood habitats for willow ptarmigan in Norway. AB - BACKGROUND: Habitat models provide information about which habitat management should target to avoid species extinctions or range contractions. The willow ptarmigan inhabits alpine- and arctic tundra habitats in the northern hemisphere and is listed as near threatened (NT) in the Norwegian red list due to declining population size. Habitat alteration is one of several factors affecting willow ptarmigan populations, but there is a lack of studies quantifying and describing habitat selection in willow ptarmigan. We used data from an extensive line transect survey program from 2014 to 2017 to develop resource selection functions (RSF) for willow ptarmigan in Norway. The selection coefficients for the RSF were estimated using a mixed-effects logistic regression model fitted with random intercepts for each area. We predicted relative probability of selection across Norway and quantile-binned the predictions in 10 RSF bins ranging from low-(1) to high-(10) relative probability of selection. RESULTS: Random cross-validation suggest that our models were highly predictive, but validation based spatial blocking revealed that the predictability was better in southern parts of Norway compared to the northernmost region. Willow ptarmigan selected for herb-rich meadows and avoided lichen rich heathlands. There was generally stronger selection for vegetation types with dense field layer and for rich bogs and avoidance of vegetation types with sparse field layer cover and for lowland forest. Further, willow ptarmigan selected for areas around the timberline and for intermediate slopes. Mapping of the RSF showed that 60% of Norway is in the lowest ranked RSF bin and only 2% in the highest ranked RSF bin. CONCLUSIONS: Willow ptarmigan selected for vegetation types with dense field layer and bogs at intermediate slopes around the timberline. Selection coincides with previous habitat selection studies on willow ptarmigan. This is the first attempt to assess and quantify habitat selection for willow ptarmigan at a large scale using data from line transect distance sampling surveys. Spatial variation in predictability suggests that habitat selection in late summer might vary from north to south. The resource selection map can be a useful tool when planning harvest quotas and habitat interventions in alpine areas. PMID- 30285718 TI - Enhancing implementation of measurement-based mental health care in primary care: a mixed-methods randomized effectiveness evaluation of implementation facilitation. AB - BACKGROUND: Mental health care lags behind other forms of medical care in its reliance on subjective clinician assessment. Although routine use of standardized patient-reported outcome measures, measurement-based care (MBC), can improve patient outcomes and engagement, clinician efficiency, and, collaboration across care team members, full implementation of this complex practice change can be challenging. This study seeks to understand whether and how an intensive facilitation strategy can be effective in supporting the implementation of MBC. Implementation researchers partnering with US Department of Veterans Affairs (VA) leaders are conducting the study within the context of a national initiative to support MBC implementation throughout VA mental health services. This study will focus specifically on VA Primary Care-Mental Health Integration (PCMHI) programs. METHODS: A mixed-methods, multiple case study design will include 12 PCMHI sites recruited from the 23 PCMHI programs that volunteered to participate in the VA national initiative. Guided by a study partnership panel, sites are clustered into similar groups using administrative metrics. Site pairs are recruited from within these groups. Within pairs, sites are randomized to the implementation facilitation strategy (external facilitation plus QI team) or standard VA national support. The implementation strategy provides an external facilitator and MBC experts who work with intervention sites to form a QI team, develop an implementation plan, and, identify and overcome barriers to implementation. The RE-AIM framework guides the evaluation of the implementation facilitation strategy which will utilize data from administrative, medical record, and primary qualitative and quantitative sources. Guided by the iPARIHS framework and using a mixed methods approach, we will also examine factors associated with implementation success. Finally, we will explore whether implementation of MBC increases primary care team communication and function related to the care of mental health conditions. DISCUSSION: MBC has significant potential to improve mental health care but it represents a major change in practice. Understanding factors that can support MBC implementation is essential to attaining its potential benefits and spreading these benefits across the health care system. PMID- 30285719 TI - Purchasers' deliberations on psychosocial needs within the process of allocating healthcare services for older home-dwelling persons with dementia: a qualitative study. AB - BACKGROUND: Meeting psychosocial needs is a significant component of quality dementia care. To enable persons with dementia to live at home for as long as possible, a community healthcare service offering care where physical, social, psychological, cultural and spiritual needs are met, is recommended. A comprehensive allocation process is required to allocate individually tailored healthcare services. However, the allocation process for older home-dwelling persons with dementia, specifically for services to safeguard psychosocial needs, remains largely unexplored. Accordingly, this study aims to explore purchasers' deliberations on psychosocial needs during the process of allocating healthcare services to older home-dwelling persons with dementia. METHODS: The study had a descriptive design with a qualitative approach. The primary data source was focus group interviews with purchasers who assess and allocate healthcare services. The interview data were supplemented by a review of administrative decisions made by the purchasers. Data from the focus group interviews were analysed using a descriptive and interpretive approach. Content analysis of the administrative decisions was conducted. RESULTS: The purchasers described the allocation process as challenging. The following four themes reflect the complexity of the allocation process: (i) an unfamiliar and unclear concept; (ii) a hierarchy of needs; (iii) an adjusting allocation process; (iv) a challenging documentation of administrative decisions. CONCLUSIONS: The purchasers viewed a comprehensive allocation process as important. However, a web of different interplaying aspects prevented the purchasers from conducting a comprehensive need-led allocation process. Insufficient assessment or allocation threatens the adequate safeguarding of the psychosocial needs of persons with dementia. Having varied and sufficient services to allocate is of great importance, but is not sufficient. Psychosocial needs must be better incorporated as a significant element throughout the entire allocation process.

AB - BACKGROUND: Distal arthrogryposis (DA) is a group of clinically and genetically heterogeneous disorders that involve multiple congenital limb contractures and comprise at least 10 clinical subtypes. Here, we describe our findings in two Chinese families: Family 1 with DA2B (MIM 601680) and Family 2 with mild DA. METHODS: To map the disease locus, two-point linkage analysis was performed with microsatellite markers closed to TPM2, TNNI2/TNNT3 and TNNC2. In Family 1, a positive LOD (logarithm of odds) score was only obtained at the microsatellite marker close to TPM2 and mutation screening was performed using direct sequencing of TPM2 in the proband. In Family 2, for the LOD score that did not favor linkage to any markers, whole-exome sequencing (WES) was performed on the proband. PCR restriction fragment length polymorphism (RFLP) and bioinformatics analysis were then applied to identify the pathogenic mutations in two families. In order to correlate genotype with phenotype in DA, retrospective analyses of phenotypic features according to the TPM2 and PIEZO2 mutation spectrums were carried out. RESULTS: A heterozygous missense mutation c.308A > G (p.Q103R) in TPM2 in Family 1, and a novel variation c.8153G > A (p.R2718Q) in PIEZO2 in Family 2 were identified. Each of the two novel variants was co-segregated with the DA manifestations in the corresponding family. Bioinformatics analysis from several tools supported the pathogenicity of the mutations. Furthermore, our study suggests that there is no relation between the types or locations of TPM2 mutations and the clinical characteristics, and that different inheritance modes and mutation types concerning PIEZO2 cause distinct clinical manifestations. CONCLUSIONS: We report two novel mutations within TPM2 and PIEZO2 responsible for DA2B and mild DA in two Chinese families, respectively. Our study expands the spectrum of causal mutations in the TPM2 and PIEZO2 genes. PMID- 30285721 TI - Evaluation of the relationship between maxillary posterior teeth and the maxillary sinus floor using cone-beam computed tomography. AB - BACKGROUND: Maxillary posterior teeth have close anatomical proximity to the maxillary sinus floor (MSF), and the race, gender, age, side and presence/absence of adjacent teeth may influence the mean distances between the root apices and the MSF. This study aimed to evaluate both the relationship between the maxillary posterior teeth and MSF, and the influence of adjacent teeth loss on the distance between the maxillary posterior roots and MSF. METHODS: Cone-beam computed tomography images were collected from 1011 Chinese patients. The relationship between the maxillary posterior teeth and the MSF was divided into three types: Type OS (the root apex extending below/outside the MSF), Type CO (the root apex contacting with the MSF), Type IS (the root apex extending above/inside the MSF). The minimum vertical distances between the maxillary posterior roots apices and the MSF were recorded. The correlations of the distances with gender and age were analyzed. The distances between the maxillary posterior root apices and the MSF with different types of adjacent teeth loss was evaluated. RESULTS: Type OS was the most common relationship of all posterior root apices (P<0.05). Type IS was highest in the palatal roots (PRs) of the maxillary first molars (MFMs) and the mesiobuccal roots (MBRs) of the maxillary second molars (MSMs) (24.8% and 21.6%) (P<0.05). The frequency of Type IS decreased with age except the premolar roots and PRs of the MSMs (P<0.05). The MBRs of the MSMs had the lowest distances to the MSF (0.8 +/- 2.5 mm), followed by the distobuccal roots of the MSMs (1.3 +/- 2.7 mm) and the PRs of the MFMs (1.4 +/- 3.4 mm) (P<0.05). Age was an important influencing factor to the mean distances while gender had little effects. The distance between the maxillary second premolar root apices and the MSF decreased with the absence of adjacent teeth (P<0.05). CONCLUSIONS: The maxillary molars showed greater proximity to the MSF than premolars. Age had significant impacts on the relationship between maxillary posterior roots and MSF. The absence of maxillary first molars will influence the proximity of maxillary second premolar root apices to MSF. PMID- 30285722 TI - Inhibition of RANKL-stimulated osteoclast differentiation by Schisandra chinensis through down-regulation of NFATc1 and c-fos expression. AB - BACKGROUND: Schisandra chinenesis (SC) has been reported to have ameliorative effect on osteoporosis. However, the mechanisms underlying the anti-osteoporosis activity of SC have not been clearly elucidated. In the present study, we determined the effects of SC on The receptor activator of NF-kB ligand (RANKL) induced osteoclastogenesis and its potential mechanism. METHODS: Raw 264.7 cells were treated with 0.6, 6 and 60 MUg/mL SC in the presence of 100 ng/mL RANKL for 7 days. RANKL-induced osteoclast formation was analyzed by tartrate resistant acid phosphatase (TRAP) staining. The osteoclast differentiation-related factors were confirmed along with TNF-alpha. RESULTS: SC inhibits the RANKL-induced osteoclast differentiation in dose-dependent manner within non-toxic concentrations. The supernatant concentrations of TNF-alpha were significantly decreased by SC treatment. In addition, osteoclastogenesis-related factors, TRAP6 and NF-kappaB, were markedly decreased by SC in RANKL-induced osteoclasts. Mechanistically, SC reduced the RANKL-triggered NFATc1 and c-fos expressions. CONCLUSIONS: Taken together, our data suggest that SC can modulate bone metabolism by suppressing RANKL-induced osteoclast differentiation. PMID- 30285723 TI - Antidiabetic activity, glucose uptake stimulation and alpha-glucosidase inhibitory effect of Chrysophyllum cainito L. stem bark extract. AB - BACKGROUND: Chrysophyllum cainito L., a tropical fruit tree, has been used as an alternative medicine for the treatment of diabetic patients in many countries. However, there is very limited scientific rationale for this medical use. The present study aimed to evaluate the antidiabetic activity of the extract from C. cainito stem bark and the possible mechanisms underlying this activity. METHODS: Phytochemistry and in vitro antioxidant capacity of the extract were studied. Hypoglycemic activity of the extract was examined in normal and alloxan-induced diabetic mice. The effect of C. cainito extract on glucose absorption and glucose uptake were conducted using mouse isolated jejunum and abdominal muscle, respectively. Finally, an in vitro effect of C. cainito extract on alpha glucosidase activity was evaluated. RESULTS: C. cainito extract possessed a strong antioxidant activity comparable to the ascorbic acid and butylated hydroxytoluene. The extract at 500 mg/kg significantly reduced the area under curve of blood glucose level in oral glucose tolerance test in normal mice. In alloxan-induced diabetic model, similar to glibenclamide, a single dose of the extract significantly decreased fasting blood glucose level from 387.17 +/- 29.84 mg/dl to 125.67 +/- 62.09 mg/dl after 6 h of administration. From the isolated jejunum experiment, the extract at any doses used did not inhibit glucose absorption. However, the extract at 50 MUg/ml significantly increased the amount of glucose uptake by abdominal muscles in the presence of insulin (P < 0.05). Lastly, it was found that the extract produced stronger inhibition of alpha glucosidase activity (IC50 = 1.20 +/- 0.09 MUg/ml) than acarbose (IC50 = 198.17 +/- 4.74 MUg/ml). CONCLUSION: Direct evidence of antidiabetic activity of C. cainito stem bark with possible modes of action, glucose uptake stimulation and alpha-glucosidase inhibitory effect, was reported for the first time herein. These data support the potential use of this plant for the treatment of diabetic patients. PMID- 30285724 TI - A training programme facilitating guideline use of occupational health professionals: a feasibility study. AB - BACKGROUND: To evaluate whether a training programme is a feasible approach to facilitate occupational health professionals' (OHPs) use of knowledge and skills provided by a guideline. METHODS: Feasibility was evaluated by researching three aspects: 'acceptability', 'implementation' and 'limited efficacy'. Statements on acceptability and implementation were rated by OHPs on 10-point visual analogue scales after following the training programme (T2). Answers were analysed using descriptive statistics. Barriers to and facilitators of implementation were explored through open-ended questions at T2, which were qualitatively analysed. Limited efficacy was evaluated by measuring the level of knowledge and skills at baseline (T0), after reading the guideline (T1) and directly after completing the training programme (T2). Increase in knowledge and skills was analysed using a non-paramatric Friedman test and post-hoc Wilcoxon signed rank tests (two tailed). RESULTS: The 38 OHPs found the training programme acceptable, judging that it was relevant (M: 8, SD: 1), increased their capability (M: 7, SD: 1), adhered to their daily practice (M: 8, SD: 1) and enhanced their guidance and assessment of people with a chronic disease (M: 8, SD: 1). OHPs found that it was feasible to implement the programme on a larger scale (M: 7, SD: 1) but foresaw barriers such as 'time', 'money' and organizational constraints. The reported facilitators were primarily related to the added value of the knowledge and skills to the OHPs' guidance and assessment, and that the programme taught them to apply the evidence in practice. Regarding limited efficacy, a significant increase was seen in OHPs' knowledge and skills over time (X2 (2) = 53.656, p < 0.001), with the median score improving from 6.3 (T0), 8.3 (T1) and 12.3 (T2). Post-hoc tests indicated a significant improvement between T0 and T1 (p < 0.001) and between T1 and T2 (p < 0.001). CONCLUSIONS: The training programme was found to be a feasible approach to facilitate OHPs' use of knowledge and skills provided by the guideline, from the perspective of OHPs generally (acceptability and implementation) and with respect to their increase in knowledge and skills in particular (limited efficacy). PMID- 30285725 TI - Feasibility, acceptability and potential sustainability of a 'diagonal' approach to health services for female sex workers in Mozambique. AB - BACKGROUND: Female sex workers (FSWs) in many settings have restricted access to sexual and reproductive health (SRH) services. We therefore conducted an implementation study to test a 'diagonal' intervention which combined strengthening of FSW-targeted services (vertical) with making public health facilities more FSW-friendly (horizontal). We piloted it over 18 months and then assessed its performance. METHODS: Applying a convergent parallel mixed-methods design, we triangulated the results of the analysis of process indicators, semi structured interviews with policy makers and health managers, structured interviews with health care providers and group discussions with peer outreach workers. We then formulated integrated conclusions on the interventions' feasibility, acceptability by providers, managers and policy makers, and potential sustainability. RESULTS: The intervention, as designed, was considered theoretically feasible by all informants, but in practice the expansion of some of the targeted services was hampered by insufficient financial resources, institutional capacity and buy-in from local government and private partners, and could not be fully actualised. In terms of acceptability, there was broad consensus on the need to ensure FSWs have access to SRH services, but not on how this might be achieved. Targeted clinical services were no longer endorsed by national government, which now prefers a strategy of making public services more friendly for key populations. Stakeholders judged that the piloted model was not fully sustainable, nor replicable elsewhere in the country, given its dependency on short-term project-based funding, lack of government endorsement for targeted clinical services, and viewing the provision of community activities as a responsibility of civil society. CONCLUSIONS: In the current Mozambican context, a 'diagonal' approach to ensure adequate access to sexual and reproductive health care for female sex workers is not fully feasible, acceptable or sustainable, because of insufficient resources and lack of endorsement by national policy makers for the targeted, vertical component. PMID- 30285726 TI - Cellular network modeling and single cell gene expression analysis reveals novel hepatic stellate cell phenotypes controlling liver regeneration dynamics. AB - BACKGROUND: Recent results from single cell gene and protein regulation studies are starting to uncover the previously underappreciated fact that individual cells within a population exhibit high variability in the expression of mRNA and proteins (i.e., molecular variability). By combining cellular network modeling, and high-throughput gene expression measurements in single cells, we seek to reconcile the high molecular variability in single cells with the relatively low variability in tissue-scale gene and protein expression and the highly coordinated functional responses of tissues to physiological challenges. In this study, we focus on relating the dynamic changes in distributions of hepatic stellate cell (HSC) functional phenotypes to the tightly regulated physiological response of liver regeneration. RESULTS: We develop a mathematical model describing contributions of HSC functional phenotype populations to liver regeneration and test model predictions through isolation and transcriptional characterization of single HSCs. We identify and characterize four HSC transcriptional states contributing to liver regeneration, two of which are described for the first time in this work. We show that HSC state populations change in vivo in response to acute challenges (in this case, 70% partial hepatectomy) and chronic challenges (chronic ethanol consumption). Our results indicate that HSCs influence the dynamics of liver regeneration through steady state tissue preconditioning prior to an acute insult and through dynamic control of cell state balances. Furthermore, our modeling approach provides a framework to understand how balances among cell states influence tissue dynamics. CONCLUSIONS: Taken together, our combined modeling and experimental studies reveal novel HSC transcriptional states and indicate that baseline differences in HSC phenotypes as well as a dynamic balance of transitions between these phenotypes control liver regeneration responses. PMID- 30285727 TI - Tinospora cordifolia as a potential neuroregenerative candidate against glutamate induced excitotoxicity: an in vitro perspective. AB - BACKGROUND: Glutamate, the major excitatory neurotransmitter of CNS acts as a neurotoxin at higher concentrations. Prolonged activation of glutamate receptors results in progressive neuronal damage by aggravating calcium influx, inducing mitochondrial damage and oxidative stress. Excitotoxic cell death is associated with the pathogenesis of various neurodegenerative disorders such as trauma, brain injury and neurodegenerative diseases. The current study was designed to investigate the neuroprotective and neuroregenerative potential of Tinospora cordifolia against glutamate-induced excitotoxicity using primary cerebellar neuronal cultures as a model system. METHODS: Monosodium salt of glutamate was used to induce neurotoxic injury in primary cerebellar neurons. Four extracts including Hexane extract, Chloroform extract, Ethyl acetate, and Butanol extract were obtained from fractionation of previously reported aqueous ethanolic extract of T. cordifolia and tested for neuroprotective activity. Out of the four fractions, Butanol extract of T. cordifolia (B-TCE) exhibited neuroprotective potential by preventing degeneration of neurons induced by glutamate. Expression of different neuronal, apoptotic, inflammatory, cell cycle regulatory and plasticity markers was studied by immunostaining and Western blotting. Neurite outgrowth and migration were also studied using primary explant cultures, wound scratch and gelatin zymogram assay. RESULTS: At molecular level, B-TCE pretreatment of glutamate-treated cultures normalized the stress-induced downregulation in the expression of neuronal markers (MAP-2, GAP-43, NF200) and anti-apoptotic marker (Bcl-xL). Further, cells exposed to glutamate showed enhanced expression of inflammatory (NF-kappaB, AP-1) and senescence markers (HSP70, Mortalin) as well as the extent of mitochondrial damage. However, B-TCE pretreatment prevented this increase and inhibited glutamate-induced onset of inflammation, stress and mitochondrial membrane damage. Furthermore, B-TCE was observed to promote regeneration, migration and plasticity of cerebellar neurons, which was otherwise significantly inhibited by glutamate treatment. CONCLUSION: These results suggest that B-TCE may have neuroprotective and neuroregenerative potential against catastrophic consequences of glutamate-mediated excitotoxicity and could be a potential therapeutic candidate for neurodegenerative diseases. PMID- 30285729 TI - Assessment of research waste part 2: wrong study populations- an exemplar of baseline vitamin D status of participants in trials of vitamin D supplementation. AB - BACKGROUND: Research waste can occur when trials are conducted in the wrong populations. Vitamin D deficient populations are most likely to benefit from vitamin D supplementation. We investigated waste attributable to randomised controlled trials (RCTs) of supplementation in populations that were not vitamin D deficient. METHODS: In December 2015, we searched Pubmed, recent systematic reviews, and three trial registries for RCTs of vitamin D with clinical endpoints in adults, and 25-hydroxvitamin D (25OHD) survey data relevant to large (N >= 1000) RCTs. We investigated the proportion of RCTs that studied vitamin D deficient populations, temporal trends in baseline 25OHD, and whether investigators in large RCTs considered relevant 25OHD survey data or systematic reviews in their trial justifications. RESULTS: Of 137 RCTs of vitamin D with clinical endpoints, 118 (86%) reported baseline mean/median 25OHD, which was < 25, 25-49, 50-74, and >= 75 nmol/L in 12 (10%), 62 (53%), 36 (31%), and 8 (7%) RCTs, respectively. In 70% of RCTs, baseline 25OHD was > 40 nmol/L. Baseline 25OHD increased over time. Before 2006, 38%, 62%, 0% and 0% of RCTs had baseline 25OHD < 25, 25-49, 50-74, and >= 75 nmol/L respectively; in 2011-15, the respective proportions were 9%, 49%, 37%, and 6%. Of 12 RCTs with baseline 25OHD < 25 nmol/L, 8 had neutral findings. Of 25 large RCTs (18 completed, 7 ongoing), 1 was undertaken in a vitamin D deficient population, 3 in vitamin D insufficient populations, and 17 had, or probably will have, baseline 25OHD > 40 nmol/L. 44% (8/18) of large completed RCTs cited relevant prior population 25OHD data, and only 3/10 (30%) relevant prior systematic reviews. CONCLUSIONS: Up to 70% of RCTs of vitamin D with clinical endpoints, 71% of large completed RCTs, and 100% of ongoing large RCTs could be considered research waste because they studied cohorts that were not vitamin D deficient. PMID- 30285730 TI - Fagus sylvatica seedlings show provenance differentiation rather than adaptation to soil in a transplant experiment. AB - BACKGROUND: Understanding and predicting the response of tree populations to climate change requires understanding the pattern and scale of their adaptation. Climate is often considered the major driver of local adaptation but, although biotic factors such as soil pathogens or mutualists could be as important, their role has typically been neglected. Biotic drivers might also interact with climate to affect performance and mycorrhizae, in particular, are likely to play a key role in determining drought resistance, which is important in the context of adaptation to future environmental change. To address these questions, we performed a fully reciprocal soil-plant transplant experiment using Fagus sylvatica seedlings and soils from three regions in Germany. To separate the biotic and abiotic effects of inoculation, half of the plants were inoculated with natural soil from the different origins, while the rest were grown on sterilized substrate. We also imposed a drought stress treatment to test for interactions between soil biota and climate. After 1 year of growth, we measured aboveground biomass of all seedlings, and quantified mycorrhizal colonization for a subset of the seedlings, which included all soil-plant combinations, to disentangle the effect of mycorrhiza from other agents. RESULTS: We found that plant origin had the strongest effect on plant performance, but this interacted with soil origin. In general, trees showed a slight tendency to produce less aboveground biomass on local soils, suggesting soil antagonists could be causing trees to be maladapted to their local soils. Consistently, we found lower mycorrhizal colonization rate under local soil conditions. Across all soils, seedlings from low elevations produced more annual biomass than middle (+ 290%) and high (+ 97%) elevations. Interestingly, mycorrhizal colonization increased with drought in the two provenances that showed higher drought tolerance, which supports previous results showing that mycorrhizae can increase drought resistance. CONCLUSIONS: Our findings suggest that soil communities play a role in affecting early performance of temperate trees, although this role may be smaller than that of seed origin. Also, other effects, such as the positive response to generalists or negative interactions with soil biota may be as important as the highly specialized mycorrhizal associations. PMID- 30285731 TI - Impact of herpes zoster and postherpetic neuralgia on the quality of life of Germans aged 50 or above. AB - BACKGROUND: Herpes zoster (HZ) is a painful dermatomal rash caused by reactivation of latent varicella zoster virus surviving in the patient's sensory ganglia after a previous episode of varicella. The incidence of HZ increases markedly with age as does the proportion of HZ patients who develop postherpetic neuralgia (PHN) with often severe and debilitating pain persisting for months and even years. This prospective study aimed to assess the impact of HZ and PHN on the quality of life (QoL) of individuals aged >= 50 years in Germany. METHODS: Patients were recruited when consulting primary care physicians for a first HZ episode. PHN was defined as a 'worst' pain score >= 3 on the Zoster Brief Pain Inventory (ZBPI) scale persisting or appearing 90 days or more after rash onset. PHN-cases were followed for up to nine months after rash onset. The interference of pain with patients' ability to carry out normal activities was assessed by the ZBPI activities of daily living (ADL) scale and QoL by the EuroQoL five-dimension scale (EQ-5D) utility score. RESULTS: Of 513 patients enrolled, 61 (11.9%) developed PHN. At HZ onset, the mean ZBPI worst pain score of all patients was 5.1, the least square (LS)means estimates of the ZBPI ADL and EQ-5D utility scores were 2.970 and 0.740, respectively. Over three months follow-up, the pain scores decreased and the QoL increased monotonically across all age groups. At Day 90, the mean ZBPI worst pain score of the PHN patients was 4.4, while the LSmeans estimates of the ZBPI ADL and EQ-5D utility scores were 2.899 and 0.826, respectively. For patients with PHN persisting at nine months, the pain scores and QoL remained unchanged over the six months following the development of PHN. CONCLUSION: HZ and PHN had a substantial impact on the patients' QoL and ability to function in their normal activities. There was a clear association in time between the evolution of pain and estimated QoL. The impact on ADL and QoL did not vary with age. PMID- 30285728 TI - The TRAX, DISC1, and GSK3 complex in mental disorders and therapeutic interventions. AB - Psychiatric disorders (such as bipolar disorder, depression, and schizophrenia) affect the lives of millions of individuals worldwide. Despite the tremendous efforts devoted to various types of psychiatric studies and rapidly accumulating genetic information, the molecular mechanisms underlying psychiatric disorder development remain elusive. Among the genes that have been implicated in schizophrenia and other mental disorders, disrupted in schizophrenia 1 (DISC1) and glycogen synthase kinase 3 (GSK3) have been intensively investigated. DISC1 binds directly to GSK3 and modulates many cellular functions by negatively inhibiting GSK3 activity. The human DISC1 gene is located on chromosome 1 and is highly associated with schizophrenia and other mental disorders. A recent study demonstrated that a neighboring gene of DISC1, translin-associated factor X (TRAX), binds to the DISC1/GSK3beta complex and at least partly mediates the actions of the DISC1/GSK3beta complex. Previous studies also demonstrate that TRAX and most of its interacting proteins that have been identified so far are risk genes and/or markers of mental disorders. In the present review, we will focus on the emerging roles of TRAX and its interacting proteins (including DISC1 and GSK3beta) in psychiatric disorders and the potential implications for developing therapeutic interventions. PMID- 30285733 TI - Secondary spontaneous pneumothorax in patients with sarcoma treated with Pazopanib, a case control study. AB - BACKGROUND: The tyrosine kinase inhibitor pazopanib is used for treatment of sarcoma. Recent studies have suggested that the use of pazopanib may lead to the development of pneumothorax, an unexpected adverse effect in patients with sarcoma metastatic to the chest. METHODS: We conducted a retrospective case control study of patients with sarcoma with metastases to the chest with pneumothorax (cases) and without pneumothorax (controls). The control population was selected from tumor registry in a 1:4 (cases to controls) ratio. The primary outcome of interest was the association between pazopanib and pneumothorax risk in patients with sarcoma metastatic to the chest. Secondary objective was to evaluate risk factors for pneumothorax. RESULTS: We identified 41 cases and 164 controls. Using purposeful selection method the odds of developing pneumothorax while being on pazopanib was not significant in univariate (p = .06) and multivariable analysis (p = .342). On univariate analysis risk factors of pneumothorax in patients with sarcoma were age, male sex, African American race, the presence of cavitary lung nodules/masses, and the presence of pleural-based nodules/masses. On multivariate analysis, only the presence of cavitary lung nodules/masses (P < .001) and the presence of pleural-based nodules/masses (P < .001) remained as risk factors for developing pneumothorax. CONCLUSION: Pazopanib does not increase the risk of pneumothorax in patients with sarcoma and evidence of metastatic disease to the chest. Presence of cavitary lung nodules/masses and the presence of pleural-based nodules/masses were found to be risk factors for pneumothorax. PMID- 30285732 TI - Utility of circulating tumor DNA in cancer diagnostics with emphasis on early detection. AB - Various recent studies have focused on analyzing tumor genetic material released into the blood stream, known as circulating tumor DNA (ctDNA). Herein, we describe current research on the application of ctDNA to cancer management, including prognosis determination, monitoring for treatment efficacy/relapse, treatment selection, and quantification of tumor size and disease burden. Specifically, we examine the utility of ctDNA for early cancer diagnostics focusing on the development of a blood test to detect cancer in asymptomatic individuals by sequencing and analyzing mutations in ctDNA. Next, we discuss the prospect of using ctDNA to test for cancer, and present our calculations based on previously published empirical findings in cancer and prenatal diagnostics. We show that very early stage (asymptomatic) tumors are not likely to release enough ctDNA to be detectable in a typical blood draw of 10 mL. Data are also presented showing that mutations in circulating free DNA can be found in healthy individuals and will likely be very difficult to distinguish from those associated with cancer.We conclude that the ctDNA test, in addition to its high cost and complexity, will likely suffer from the same issues of low sensitivity and specificity as traditional biomarkers when applied to population screening and early (asymptomatic) cancer diagnosis. PMID- 30285734 TI - Long-term feeding with high plant protein based diets in gilthead seabream (Sparus aurata, L.) leads to changes in the inflammatory and immune related gene expression at intestinal level. AB - BACKGROUND: In order to ensure sustainability of aquaculture production of carnivourous fish species such as the gilthead seabream (Sparus aurata, L.), the impact of the inclusion of alternative protein sources to fishmeal, including plants, has been assessed. With the aim of evaluating long-term effects of vegetable diets on growth and intestinal status of the on-growing gilthead seabream (initial weight = 129 g), three experimental diets were tested: a strict plant protein-based diet (VM), a fishmeal based diet (FM) and a plant protein based diet with 15% of marine ingredients (squid and krill meal) alternative to fishmeal (VM+). Intestines were sampled after 154 days. Besides studying growth parameters and survival, the gene expression related to inflammatory response, immune system, epithelia integrity and digestive process was analysed in the foregut and hindgut sections, as well as different histological parameters in the foregut. RESULTS: There were no differences in growth performance (p = 0.2703) and feed utilization (p = 0.1536), although a greater fish mortality was recorded in the VM group (p = 0.0141). In addition, this group reported a lower expression in genes related to pro-inflammatory response, as Interleukine-1beta (il1beta, p = 0.0415), Interleukine-6 (il6, p = 0.0347) and cyclooxigenase-2 (cox2, p = 0.0014), immune-related genes as immunoglobulin M (igm, p = 0.0002) or bacterial defence genes as alkaline phosphatase (alp, p = 0.0069). In contrast, the VM+ group yielded similar survival rate to FM (p = 0.0141) and the gene expression patterns indicated a greater induction of the inflammatory and immune markers (il1beta, cox2 and igm). However, major histological changes in gut were not detected. CONCLUSIONS: Using plants as the unique source of protein on a long term basis, replacing fishmeal in aqua feeds for gilthead seabream, may have been the reason of a decrease in the level of different pro-inflammatory mediators (il1 beta, il6 and cox2) and immune-related molecules (igm and alp), which reflects a possible lack of local immune response at the intestinal mucosa, explaining the higher mortality observed. Krill and squid meal inclusion in vegetable diets, even at low concentrations, provided an improvement in nutrition and survival parameters compared to strictly plant protein based diets as VM, maybe explained by the maintenance of an effective immune response throughout the assay. PMID- 30285735 TI - Staff empowerment and engagement in a magnet(r) recognized and joint commission international accredited academic centre in Belgium: a cross-sectional survey. AB - BACKGROUND: A substantial number of studies linked aspects of a balanced, healthy and supportive nurse practice environment with quality and patient safety. To what extent balanced work characteristics such as social capital, decision latitude and workload are relevant for all staff engaged in patient care including healthcare and medical staff in a Magnet Recognized and Joint Commission International accredited academic centre is unclear. The study aim is to investigate associations between work characteristics such as social capital, decision latitude and workload, work engagement and feelings of burnout as explanatory variables and job satisfaction, turnover intentions and perceived quality of care as dependent variables in a study population of nursing, healthcare and medical staff taken in account generation differences. METHODS: Hierarchical regression analysis estimated strength of associations with demographic characteristics (block-1), professional category (block-2), work characteristics (block-3) and work engagement or burnout dimensions (block-4) as explanatory variables of job satisfaction and turnover intention and quality of care as outcome variables. RESULTS: The study confirmed and extended previous study findings demonstrating positive impact on staff' job outcomes and assessed quality of care by balanced work characteristics such as social capital, decision latitude and workload in nursing staff (N = 864), healthcare staff (N = 131) and medical staff (N = 241). Generational characteristics and professional category were associated with turnover intentions and less favorable assessed quality of care, respectively. Explained variances of studied models ranged from 14.4 to 45.7%. CONCLUSION: Engaging and committing staff to promote excellent patient outcomes in daily interdisciplinary practice works through clear frameworks, methods and resources supported by governance and policy structure that makes outcomes visible and accountable. PMID- 30285736 TI - Good response to PAH-targeted drugs in a PVOD patient carrying Biallelic EIF2AK4 mutation. AB - Pulmonary veno-occlusive disease (PVOD) is a rare and fatal cause of pulmonary arterial hypertension (PAH). Different from other types of PAH, PVOD patients have a dismal prognosis because of the progressive nature of pulmonary vascular involvement and fatal pulmonary edema induced by PAH-targeted drugs. Lung transplantation is the only choice for these patients. In a recent article published in the journal, Yang and his colleagues found pulmonary edema was not demonstrated in 2 of the 6 PVOD patients injected with prostacyclin analogues (a kind of PAH-targeted drug). Regretfully, none of these 6 patients underwent microscopic examination of lung tissues. Here, we reported a sporadic PVOD patient evidenced by pathology and EIF2AK4 biallelic mutation. The patient was followed over the course of 3 years in our center. During the 3 years, he was admitted into our hospital for many times for the acute exacerbation of pulmonary hypertension. However, after treatment with many kinds of PAH-targeted drugs, the pulmonary hypertension was in control and he feel better every time. The present patient displayed different treatment response comparing with previous reports. It suggests that PVOD is a heterogeneity population and different patients have different characteristics including clinical manifestation, genomics, treatment response et al. How to pick off this portion of patients timely is the core issue. Lots of important works are necessary to answer this question. However, we can see a glimmer of hope form this patient at least. PMID- 30285737 TI - Sense and sensibility: on the diagnostic value of control chart rules for detection of shifts in time series data. AB - BACKGROUND: The aim of this study was to quantify and compare the diagnostic value of The Western Electric (WE) statistical process control (SPC) chart rules and the Anhoej rules for detection of non-random variation in time series data in order to make recommendations for their application in practice. METHODS: SPC charts are point-and-line graphs showing a measure over time and employing statistical tests for identification of non-random variation. In this study we used simulated time series data with and without non-random variation introduced as shifts in process centre over time. The primary outcome was likelihood ratios of combined tests. Likelihood ratios are useful measures of a test's ability to discriminate between the true presence or absence of a specific condition. RESULTS: With short data series (10 data points), the WE rules 1-4 combined and the Anhoej rules alone or combined with WE rule 1 perform well for identifying or excluding persistent shifts in the order of 2 SD. For longer data series, the Anhoej rules alone or in combination with the WE rule 1 seem to perform slightly better than the WE rules combined. However, the choice of which and how many rules to apply in a given situation should be made deliberately depending on the specific purpose of the SPC analysis and the number of available data points. CONCLUSIONS: Based on these results and our own practical experience, we suggest a stepwise approach to SPC analysis: Start with a run chart using the Anhoej rules and with the median as process centre. If, and only if, the process shows random variation at the desired level, apply the 3-sigma rule in addition to the Anhoej rules using the mean as process centre. PMID- 30285738 TI - Variability in antifungal utilization among neonatal, pediatric, and adult inpatients in academic medical centers throughout the United States of America. AB - BACKGROUND: Identification of factors associated with antifungal utilization in neonatal, pediatric, and adult patient groups is needed to guide antifungal stewardship initiatives in academic medical centers. METHODS: For this hospital level analysis, we analyzed antifungal use in hospitals across the United States of America, excluding centers only providing care for hematology/oncology patients. Analysis of variance was used to compare antifungal use between patient groups. Three multivariable linear regression models were used to determine independent factors associated with antifungal use in the neonatal, pediatric, and adult patient groups. RESULTS: For the neonatal, pediatric, and adult patient groups, 54, 44, and 60 hospitals were included, respectively. Total antifungal use was significantly lower in the neonatal patient group (14 days of therapy (DOT)/1000 patient days (PDs) versus 76 in pediatrics and 74 in adults, p < 0.05). There were no significant associations identified with total antifungal DOT/1000 PDs in the neonatal patient group (model R2 = 0.11). In the pediatric patient group (model R2 = 0.55), admission to immunosuppressed service lines and total broad-spectrum antibiotic use were positively associated with total antifungal use (coefficients of 1.95 and 0.41, both p < 0.05). In the adult patient group (model R2 = 0.79), admission to immunosuppressed service lines, total invasive fungal infections, and total broad-spectrum antibiotic use were positively associated with total antifungal use (coefficients of 5.08, 5.17, and 0.137, all p < 0.05). CONCLUSIONS: Variability in antifungal use in the neonatal group could not be explained well, whereas factors were associated with antifungal use in the adult and pediatric patient groups. These data can help guide antifungal stewardship initiatives. PMID- 30285740 TI - Correction to: Oral administration of inactivated porcine epidemic diarrhea virus activate DCs in porcine Peyer's patches. AB - The original article [1] contained an error whereby the leftmost graph in Fig. 1A mistakenly had its x-axis labelled as 'CFST'; this has now been corrected to 'CFSE'. PMID- 30285741 TI - Rectal, central venous, gastric and bladder pressures versus esophageal pressure for the measurement of cough strength: a prospective clinical comparison. AB - BACKGROUND: Cough pressure, an expression of expiratory muscle strength, is usually measured with esophageal or gastric balloons, but these invasive catheters can be uncomfortable for the patient or their placement impractical. Because pressure in the thorax and abdomen are expected to be similar during a cough, we hypothesized that measurement at other thoracic or abdominal locations might also be similar as well as useful in clinical scenarios. This study aimed to compare cough pressures measured at thoracic and abdominal sites that could serve as alternatives to esophageal pressures (Pes). METHODS: Nine patients scheduled for laparotomy were asked to cough as forcefully as possible from total lung capacity in supine position. Three cough maneuvers were performed while Pes (the gold standard) as well as gastric, central venous, bladder and rectal pressures (Pga, Pcv, Pbl, and Prec, respectively) were measured simultaneously. The intraclass correlation coefficient (ICC) was used to evaluate the repeatability of the measurements in each patient at each site and evaluate agreement between alternative sites (Pga, Pcv, Pbl, and Prec) and Pes. Bland Altman plots were used to compare Pes and the measurements at the other sites. RESULTS: Median (first quartile, third quartile) maximum pressures were as follows: Pes 112 (89,148), Pga 105 (92,156), Pcv 102 (91,149), Pbl 118 (93,157), and Prec 103 (88,150) cmH2O. The ICCs showed excellent within-site repeatability of the measurements (p < 0.001) and excellent agreement between alternative sites and Pes (p < 0.004). The Bland-Altman plots showed minimal differences between Pes, Pga, Pcv, and Prec. However, Pbl was higher than the other pressures in most patients, and the difference between Pes and Pbl was slightly larger. CONCLUSIONS: Cough pressure can be measured in the esophagus, stomach, superior vena cava or rectum, since their values are similar. It can also be measured in the bladder, although the value will be slightly higher. These results potentially facilitate the assessment of dynamic expiratory muscle strength with fewer invasive catheter placements in most hospitalized patients, thus providing an option that will be particularly useful in those undergoing thoracic or abdominal surgery.

AB - BACKGROUND: The WW domain-containing oxidoreductase (WWOX) gene, frequently altered in breast cancer, encodes a tumor suppressor whose function is mediated through its interactions with cancer-related proteins, such as the pro-apoptotic protein p73alpha. RESULTS: To better understand the involvement of WWOX in breast tumorigenesis, we performed a yeast two-hybrid screen and co-immunoprecipitation assays to identify novel partners of this protein. We characterized the vesicular overexpressed in cancer pro-survival protein 1 (VOPP1) as a new regulator of WWOX. In breast cancer cells, VOPP1 sequestrates WWOX in lysosomes, impairs its ability to associate with p73alpha, and inhibits WWOX-dependent apoptosis. Overexpressed VOPP1 potentiates cellular transformation and enhances the growth of transplanted tumors in vivo. VOPP1 is overexpressed in breast tumors, especially in tumors that retain WWOX. Moreover, increased expression of VOPP1 is associated with reduced survival of patients with WWOX-positive, but not with WWOX-negative, tumors. CONCLUSIONS: These findings emphasize the importance of the sequestration of WWOX by VOPP1 in addition to WWOX loss in breast tumors and define VOPP1 as a novel oncogene promoting breast carcinogenesis by inhibiting the anti-tumoral effect of WWOX. PMID- 30285742 TI - Developing and evaluating clinical leadership interventions for frontline healthcare providers: a review of the literature. AB - BACKGROUND: The importance of clinical leadership in ensuring high quality patient care is emphasized in health systems worldwide. Of particular concern are the high costs to health systems related to clinical litigation settlements. To avoid further cost, healthcare systems particularly in High-Income Countries invest significantly in interventions to develop clinical leadership among frontline healthcare workers at the point of care. In Low-Income Countries however, clinical leadership development is not well established. This review of the literature was conducted towards identifying a model to inform clinical leadership development interventions among frontline healthcare providers, particularly for improved maternal and newborn care. METHODS: A structural literature review method was used, articles published between 2004 and 2017 were identified from search engines (Google Scholar and EBSCOhost). Additionally, electronic databases (CINHAL, PubMed, Medline, Academic Search Complete, Health Source: Consumer, Health Source: Nursing/Academic, Science Direct and Ovid(r)), electronic journals, and reference lists of retrieved published articles were also searched. RESULTS: Employing pre-selected criteria, 1675 citations were identified. After screening 50 potentially relevant full-text papers for eligibility, 24 papers were excluded because they did not report on developing and evaluating clinical leadership interventions for frontline healthcare providers, 2 papers did not have full text available. Twenty-four papers met the inclusion criteria for review. Interventions for clinical leadership development involved the development of clinical skills, leadership competencies, teamwork, the environment of care and patient care. Work-based learning with experiential teaching techniques is reported as the most effective, to ensure the clinical leadership development of frontline healthcare providers. CONCLUSIONS: All studies reviewed arose in High-Income settings, demonstrating the need for studies on frontline clinical leadership development in Low-and Middle-Income settings. Clinical leadership development is an on-going process and must target both novice and veteran frontline health care providers. The content of clinical leadership development interventions must encompass a holistic conceptualization of clinical leadership, and should use work-based learning, and team-based approaches, to improve clinical leadership competencies of frontline healthcare providers, and overall service delivery. PMID- 30285743 TI - High dissolved oxygen tension triggers outer membrane vesicle formation by Neisseria meningitidis. AB - BACKGROUND: Outer membrane vesicles (OMVs) are nanoparticles released by Gram negative bacteria and can be used as vaccines. Often, detergents are used to promote release of OMVs and to remove the toxic lipopolysaccharides. Lipopolysaccharides can be detoxified by genetic modification such that vesicles spontaneously produced by bacteria can be directly used as vaccines. The use of spontaneous OMVs has the advantage that no separate extraction step is required in the purification process. However, the productivity of spontaneous OMVs by bacteria at optimal growth conditions is low. One of many methods for increasing OMV formation is to reduce the linkage of the outer membrane to the peptidoglycan layer by knocking out the rmpM gene. A previous study showed that for Neisseria meningitidis this resulted in release of more OMVs. Furthermore, cysteine depletion was found to trigger OMV release and at the same time cause reduced growth and oxidative stress responses. Here we study the effect of growth rate and oxidative stress on OMV release. RESULTS: First, we identified using chemostat and accelerostat cultures of N. meningitidis that increasing the growth rate from 0.03 to 0.18 h-1 has a limited effect on OMV productivity. Thus, we hypothesized that oxidative stress is the trigger for OMV release and that oxidative stress can be introduced directly by increasing the dissolved oxygen tension of bacterial cultures. Slowly increasing oxygen concentrations in a N. meningitidis changestat showed that an increase from 30 to 150% air saturation improved OMV productivity four-fold. Batch cultures controlled at 100% air saturation increased OMV productivity three-fold over batch cultures controlled at 30% air saturation. CONCLUSION: Increased dissolved oxygen tension induces the release of outer membrane vesicles in N. meningitidis cultures. Since oxygen concentration is a well-controlled process parameter of bacterial cultures, this trigger can be applied as a convenient process parameter to induce OMV release in bacterial cultures. Improved productivity of OMVs not only improves the production costs of OMVs as vaccines, it also facilitates the use of OMVs as adjuvants, enzyme carriers, or cell-specific drug delivery vehicles. PMID- 30285744 TI - Cost-effectiveness analysis of doctor-pharmacist collaborative prescribing for venous thromboembolism in high risk surgical patients. AB - BACKGROUND: Current evidence to support cost effectiveness of doctor- pharmacist collaborative prescribing is limited. Our aim was to evaluate inpatient prescribing of venous thromboembolism (VTE) prophylaxis by a pharmacist in an elective surgery pre-admission clinic against usual care, to measure any benefits in cost to the healthcare system and quality adjusted life years (QALYs) of patients. METHOD: A decision tree model was developed to assess cost effectiveness of pharmacist prescribing compared with usual care for VTE prophylaxis in high risk surgical patients. Data from the literature was used to inform decision-tree probabilities, utility, and cost outcomes. In the intervention arm, a pharmacist prescribed patient's regular medications, documented a VTE risk assessment and prescribed VTE prophylaxis. In the usual care arm, resident medical officers were responsible for prescribing regular medications, and for risk assessment and prescribing of VTE prophylaxis. The base scenario assessed the cost effectiveness of a pre-existing pre-admission clinic pharmacy service that takes on a collaborative prescribing role. The alternative scenario assessed the benefits of introducing a pre-admission clinic pharmacy service where previously there had not been one. Probabilistic sensitivity analysis was conducted to explore uncertainty in the model. RESULTS: In both the base-case scenario and the alternative scenario pharmacist prescribing resulted in an increase in the proportion of patients adequately treated and a decrease in the incidence of VTE resulting in cost savings and improvement in quality of life. The cost savings were $31 (95% CI: -$97, $160) per patient in the base scenario and $12 (95% CI: -$131, $155) per patient in the alternative scenario. In both scenarios the pharmacist-doctor prescribing resulted in an increase in QALYs of 0.02 (95% CI: -0.01, 0.005) per patient. The probability of being cost effective at a willingness to pay off $40,000 was 95% in the base scenario and 94% in the alternative scenario. CONCLUSION: Delegation of the prescribing of VTE prophylaxis for high risk surgical patients to a pharmacist prescriber in PAC, as part of a designated scope of practice, would result in fewer cases of VTE and associated lower costs to the healthcare system and increased QALYs gained by patients. TRIAL REGISTRATION: Pre admission clinic study registered with ANZCTR ACTR Number ACTRN12609000426280 . PMID- 30285745 TI - Demographic, psychosocial and clinical factors associated with postpartum depression in Kenyan women. AB - BACKGROUND: Few longitudinal studies have examined associations between risk factors during pregnancy and mental health outcomes during the postpartum period. We used a cohort study design to estimate the prevalence, incidence and correlates of significant postpartum depressive symptoms in Kenyan women. METHODS: We recruited adult women residing in an urban, resource-poor setting and attending maternal and child health clinics in two public hospitals in Nairobi, Kenya. A translated Kiswahili Edinburgh Postpartum Depression Scale was used to screen for depressive symptoms at baseline assessment in the 3rd trimester and follow up assessment at 6-10 weeks postpartum. Information was collected on potential demographic, psychosocial and clinical risk variables. Potential risk factors for postpartum depression were evaluated using multivariate logistic regression analysis. RESULTS: Out of the 171 women who were followed up at 6-10 weeks postpartum, 18.7% (95% CI: 13.3-25.5) were found to have postpartum depression using an EPDS cut off of 10. In multivariate analyses, the odds of having postpartum depression was increased more than seven-fold in the presence of conflict with partner (OR = 7.52, 95% CI: 2.65-23.13). The association between antepartum and postpartum depression was quite strong but did not reach statistical significance (OR = 3.37, 95% CI: 0.98-11.64). CONCLUSIONS: The high prevalence of significant postnatal depressive symptoms among Kenyan women underscores the need for addressing this public health burden. Depression screening and psychosocial support interventions that address partner conflict resolution should be offered as part of maternal health care. PMID- 30285746 TI - Patient capacity for self-care in the medical record of patients with chronic conditions: a mixed-methods retrospective study. AB - BACKGROUND: Patients with chronic conditions must mobilize capacity to access and use healthcare and enact self-care. In order for clinicians to create feasible treatment plans with patients, they must appreciate the limits and possibilities of patient capacity. This study seeks to characterize the amount, nature, and comprehensiveness of the information about patient capacity documented in the medical record. METHODS: In this mixed-methods study, we extracted notes about 6 capacity domains from the medical records of 100 patients receiving care from 15 primary care clinicians at a single practice. Using a generalized linear model to account for repeated measures across multiple encounters, we calculated the rate of documented domains per encounter per patient adjusted for appointment type and number. Following quantitative analyses, we purposefully selected records to conduct inductive content analysis. RESULTS: After adjusting for number of appointments and appointment type, primary care notes contained the most mentions of capacity. Physical capacity was most noted, followed by personal, emotional, social, financial, and environmental. Qualitatively, we found three documentation patterns: patients with broad capacity notes, patients with predominantly physical domain capacity notes, and patients with capacity notes mostly in domains other than physical. Records contained almost no mention of patients' environmental or financial capacity, or of how they coped with capacity limitations. Rarely, did notes ever mention how well patients interacted with their social network or what support they provided to the patient in managing their health. CONCLUSION: Medical records scarcely document patient capacity. This may impair the ability of clinicians to determine how patients can handle patient work, at what point patient capacity might become overwhelmed leading to poor adherence and health outcomes, and how best to craft feasible treatment programs that patients can implement with high fidelity. PMID- 30285747 TI - In silico characterization of the global Geobacillus and Parageobacillus secretome. AB - BACKGROUND: Geobacillus and Parageobacillus are two ecologically diverse thermophilic genera within the phylum Firmicutes. These taxa have long been of biotechnological interest due to their ability to secrete thermostable enzymes and other biomolecules that have direct applications in various industrial and clinical fields. Despite the commercial and industrial interest in these microorganisms, the full scope of the secreted protein, i.e. the secretome, of Geobacillus and Parageobacillus species remains largely unexplored, with most studies focusing on single enzymes. A genome-wide exploration of the global secretome can provide a platform for understanding the extracellular functional "protein cloud" and the roles that secreted proteins play in the survival and adaptation of these biotechnologically relevant organisms. RESULTS: In the present study, the global secretion profile of 64 Geobacillus and Parageobacillus strains, comprising 772 distinct proteins, was predicted using comparative genomic approaches. Thirty-one of these proteins are shared across all strains used in this study and function in cell-wall/membrane biogenesis as well as transport and metabolism of carbohydrates, amino acids and inorganic ions. An analysis of the clustering patterns of the secretomes of the 64 strains according to shared functional orthology revealed a correlation between the secreted profiles of different strains and their phylogeny, with Geobacillus and Parageobacillus species forming two distinct functional clades. CONCLUSIONS: The in silico characterization of the global secretome revealed a metabolically diverse set of secreted proteins, which include proteases, glycoside hydrolases, nutrient binding proteins and toxins. PMID- 30285748 TI - The moderate predictive value of serial serum CRP and PCT levels for the prognosis of hospitalized community-acquired pneumonia. AB - BACKGROUND: To predict the prognosis by observing the dynamic change of C reactive protein (CRP) and procalcitonin (PCT) for hospitalized community acquired pneumonia (CAP). METHODS: The data were collected from January to December 2017 from the first affiliated Hospital of Zhengzhou University. Demographic and clinical patient information including age, length of hospital stay and Charlson Comorbidity Index (CCI) were recorded. Blood samples were taken for CRP, PCT, and white blood cell count (WBC). Receiver Operating Characteristic (ROC) curve was used to verify each biomarker's association with the prognosis of pneumonia. RESULTS: A total of 350 patients were enrolled in the study. The 30 day mortality was 10.86%. Serial serum CRP3, CRP5, PCT3, PCT5 and PCT5c levels were statistically lower in CAP survivors than non-survivors. CRP3c < 0, CRP5c < 0 and PCT5c < 0 were observed with a statistically lower frequency in patients with 30-day mortality and initial treatment failure. The AUC for 30-day mortality for serial CRP levels combined with CRP clearances was 0.85 (95% CI 0.77-0.92), as compared to an AUC of 0.81 (95% CI 0.73-0.9) for serial PCT levels combined with PCT clearances. CONCLUSIONS: Serum serial CRP and PCT levels had moderate predictive value for hospitalized CAP prognosis. The dynamic CRP and PCT changes may potentially be used in the future to predict hospitalized CAP prognosis. PMID- 30285749 TI - Co-culture of Bacillus amyloliquefaciens ACCC11060 and Trichoderma asperellum GDFS1009 enhanced pathogen-inhibition and amino acid yield. AB - BACKGROUND: Bacillus spp. are a genus of biocontrol bacteria widely used for antibiosis, while Trichoderma spp. are biocontrol fungi that are abundantly explored. In this study, a liquid co-cultivation of these two organisms was tried firstly. RESULTS AND DISCUSSION: Through liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS), it was discovered that with an inoculation in the ratio of 1.9:1, the antimicrobial effect of the co-cultured fermentation liquor of Bacillus amyloliquefaciens ACCC11060 and Trichoderma asperellum GDFS1009 was found to be significantly higher than that of pure cultivation. A raise in the synthesis of antimicrobial substances contributed to this significant increase. Additionally, a co-culture with the inoculation of the two organisms in the ratio of 1:1 was found to enhance the production of specific amino acids. This technique could be further explored for either a large scale production of amino acids or could serve as a theoretical base for the generation of certain rare amino acids. CONCLUSIONS: This work clearly demonstrated that co cultivation of B. amyloliquefaciens ACCC11060 and T. asperellum GDFS1009 could produce more specific biocontrol substances and amino acids. PMID- 30285750 TI - Strategy to improve malaria surveillance system preventing transfusion transmitted malaria in blood banks using molecular diagnostic. AB - BACKGROUND: Malaria can be transmitted by blood transfusion through donations collected from asymptomatic or parasitic donors. The parasites are released into the bloodstream during its life cycle and will therefore be present in donated blood by infected individuals. All cases of transfusion-transmitted malaria (TTM) notified since 2005 in Brazil were fatal. A good screening tool for Plasmodium spp. detection in blood units must have a high detection threshold, and the prevention of TTM relies entirely on the exclusion of potentially infected donors. However, in Brazilian blood banks, the screening test relies on blood thick smears examination. METHODS: The molecular diagnostic based on mitochondrial DNA (mtDNA) using real time PCR (mt-qPCR) was improved to detect Plasmodium falciparum, Plasmodium vivax, and standardized for use in Plasmodium malariae. The analytic sensitivity of this mt-qPCR methodology was performed using a sample of P. vivax. RESULTS: The mt-qPCR was highly efficient, and the analytic sensitivity for P. vivax was determined (0.000006 parasites/uL). This method was tested to detect P. vivax and P. falciparum in individuals from two malaria-endemic areas in Brazil, Amazon region (Para and Rondonia states), the samples were collected in 10 reference units of two blood banks (Para/nine cities and Rondonia/Porto Velho), and parasites mtDNA were detected in 10 of 2224 potential blood donors (0.45%). In all 10 positive samples, only P. vivax was detected. CONCLUSION: Molecular diagnostic using mt-qPCR was effective in revealing infected potential donors with good perspectives to be applied as screening routine of asymptomatic carriers for preventing transfusion-transmitted malaria in blood banks. PMID- 30285751 TI - Quantification of Clostridioides (Clostridium) difficile in feces of calves of different age and determination of predominant Clostridioides difficile ribotype 033 relatedness and transmission between family dairy farms using multilocus variable-number tandem-repeat analysis. AB - BACKGROUND: Community acquired Clostridioides (Clostridium) difficile infection (CA-CDI) is a significant health problem in human and veterinary medicine. Animals are often considered as potential reservoirs for CA-CDI. In Europe, family farming is the most predominant farming operation, with a complex interaction between animals and the community. Therefore, it is pertinent to evaluate transmission patterns of C. difficile on such prominent European farming model. Fecal samples from calves (n = 2442) were collected biweekly over a period of one year on 20 mid-size family dairy farms. Environmental samples (n = 475) were collected in a three month interval. Clostridioides difficile was detected using qPCR in 243 fecal samples (243/2442); positive samples were then quantified. Association between prevalence/load of C. difficile and age of the calves was estimated with logistic regression model. Most common C. difficile isolate from calves (n = 76) and the environment (n = 14) was C. difficile ribotype 033, which was further analyzed using multilocus variable-number tandem repeat analysis (MLVA) to assess intra- and between-farm relatedness. RESULTS: Clostridioides difficile was detected in feces of calves less than 24 h old. Results showed a non-linear statistically significant decrease in shedding load of C. difficile with age (P < 0.0001). A nonlinear relationship was also established between the number of calves and the farm C. difficile prevalence, whereas the prevalence of C. difficile ribotype 033 increased linearly with the number of calves. MLVA revealed close intra-farm relatedness among C. difficile ribotypes 033. It also revealed that the between-farms close relatedness of C. difficile ribotypes 033 can be a direct result of farm to farm trade of calves. CONCLUSIONS: Implementation of better hygiene and management measures on farms may help decrease the risk of spreading CA-CDI between animals and the community. Trading calves older than 3 weeks would decrease the possibility C. difficile dissemination in the community because of lower prevalence and lower load of C. difficile in feces. PMID- 30285752 TI - Investigation of methicillin-resistant Staphylococcus aureus among clinical isolates from humans and animals by culture methods and multiplex PCR. AB - BACKGROUND: Staphylococcus aureus is responsible for large numbers of hospital related and community-acquired infections. In this study, we investigated the presence of S. aureus and methicillin-resistant S. aureus (MRSA) in 100 samples from animals (55 cattle, 36 dogs, and 9 cats) and 150 samples from hospitalized human patients. The samples were collected from healthy and diseased animals and from diseased humans and included milk, wound swab, pus, exudates, nasal swab and diabetic ulcer. Initially, S. aureus was isolated and identified by colony morphology, Gram staining, and biochemical tests (catalase and coagulase tests). The S. aureus-positive samples were examined by polymerase chain reaction (PCR) to determine their MRSA status. RESULTS: Of the 100 animal samples, 29 were positive for S. aureus. Four samples (13.8%) from dogs were MRSA-positive, but samples from cattle and cats were MRSA-negative. Of the 150 human samples we collected, 64 were S. aureus-positive and, of these, 34 (53.1%) were MRSA positive. Most (28%) of the MRSA samples were isolated from surgical wound swabs, followed by the pus from skin infections (11%), exudates from diabetic ulcers (6%), exudates from burns (4%), and aural swabs (3%). By contrast, a low MRSA detection rate (n = 4) was seen in the non-human isolates, where all MRSA bacteria were isolated from nasal swabs from dogs. The antimicrobials susceptibility testing results showed that S. aureus isolates with mecA genes showed resistance to penicillin (100%), oxacillin (100%), erythromycin (73.5%), ciprofloxacin (70.6%), and gentamicin (67.7%). The lowest resistance was found against ceftazidime, and no vancomycin-resistant isolates were obtained. CONCLUSIONS: We detected S. aureus and MRSA in both human and canine specimens. Isolates were found to be resistant to some of the antimicrobials available locally. MRSA carriage in humans and animals appears to be a great threat to effective antimicrobials treatment. The prudent use of antimicrobials will reduce the antimicrobial resistance. Our findings will help to find the most appropriate treatment and to reduce antimicrobial resistance in the future by implementing prudent use of antimicrobials. Further studies are required to better understand the epidemiology of MRSA human-animal inter-species transmission in Bangladesh. PMID- 30285753 TI - Determinants of having no general practitioner in Germany and the influence of a migration background: results of the German health interview and examination survey for adults (DEGS1). AB - BACKGROUND: It is aspired in the German healthcare system that general practitioners (GPs) act as initial contact for patients and guide through at all steps of medical treatment. This study aims at identifying factors associated with the odds of having no GP within the general population and especially among people with migration background. METHODS: This cross-sectional analysis was based on the "German Health Interview and Examination Survey for Adults" (DEGS1) conducted by the Robert Koch Institute. Descriptive analyses as well as multiple logistic regression models were performed to analyse the impact of a migration background, age, gender, residential area, socioeconomic status (SES) and other factors on having no GP among 7755 participants. RESULTS: 9.5% of the total study population and 14.8% of people with a migration background had no GP, especially men, adults living in big cities and without chronic diseases. The odds of not having a GP were higher for people with a two-sided migration background (aOR: 1.90, 95% CI: 1.42-2.55). Among the population with a migration background, particularly young adults, men, people living in big cities and having a private health insurance showed higher odds to have no GP. CONCLUSIONS: It is necessary to investigate the causes of the differing utilization of healthcare of people with a migration background and, if necessary, to take measures for an equal access to healthcare for all population groups. Further research needs to be done to evaluate how to get young people into contact with a GP. PMID- 30285754 TI - Childbirth fear and related factors among pregnant and postpartum women in Malawi. AB - BACKGROUND: Childbirth fear is a health concern in women living in high-income countries; however, little is known about childbirth fear among women living in low-income countries like Malawi. In this study, we explored childbirth fear and associated factors among pregnant and postpartum women in Malawi. METHODS: A cross-sectional study of 152 pregnant and 153 postpartum women was conducted at a district hospital in Malawi. Participants were assessed for childbirth fear using the Wijma Delivery Expectancy/Experience Questionnaire (WDEQ). Demographic and obstetric variables were collected using a structured questionnaire. The Multidimensional Scale of Perceived Social Support (MSPSS) was used to measure social support. Using a multinomial logistic regression, factors related to childbirth fears were examined, namely demographic and obstetric characteristics, and social support. RESULTS: The mean age of participants was 26 (standard deviation: 6.4) years. During pregnancy, 39% women reported a low level of fear, 41% reported moderate fear, and 20% reported high fear; while after birth, 49, 41, and 10% women reported low, moderate, and high fear, respectively. Pregnant women who were illiterate (odds ratio (OR): 5.0, p < 0.01) or unemployed (OR: 12.6, p < 0.01) were more likely to report moderate and high fear. Postpartum mothers who were illiterate (OR: 4.2, p < 0.01) or unemployed (OR: 11.8, p < 0.01) were more likely to have moderate and high fear. Furthermore, postpartum women who sustained perineal tears had significantly higher odds of experiencing moderate (OR: 5.3, p < 0.01) or high (OR: 19.9, p < 0.01) fear than their counterparts. CONCLUSIONS: Childbirth fear is common in Malawi, and pregnant women are more likely to experience high levels of fear than postpartum women. This study highlighted the connection between childbirth fear with mother's education, employment, and perineal tears during delivery. Identifying and developing interventions for women with these associated characteristics is of clinical importance for the reduction of childbirth fear before and after childbirth in Malawi. PMID- 30285755 TI - Latina mothers as agents of change in children's eating habits: findings from the randomized controlled trial Entre Familia: Reflejos de Salud. AB - BACKGROUND: Few children consume sufficient servings of fruits and vegetables. Interventions aiming to improve children's dietary intake often target parent level factors, but limited research has examined the mediating role of parental factors on children's dietary intake. This study examined 10-month follow up data from the Entre Familia: Reflejos de Salud (Within the Family: Reflections of Health) trial to investigate (1) intervention effects on children's dietary intake, both sustained and new changes, and (2) whether changes in mothers' dietary intake, her parenting strategies, and behavioral strategies to promoting healthy eating in the home mediated changes in children's dietary intake. METHODS: Participants were 361 Mexican-origin families living in Imperial County, California. Families were randomly assigned to a 4-month dietary intervention or a delayed treatment control group. The intervention was delivered by promotoras (community health workers) via home visits and telephone calls. Assessments occurred at baseline, and 4- and 10-months post-baseline. RESULTS: At 10-months post-baseline, sustained intervention effects were observed on children's reported intake of varieties of vegetables, with differences getting larger over time. However, differential intervention effects on fast food were not sustained due to significant reductions in the control group compared with smaller changes in the intervention group. New intervention effects were observed on servings of sugar-sweetened beverages. However, the intervention continued to have no effect on children's reported fruit and vegetable servings, and varieties of fruits consumed. Mother-reported behavioral strategies to increase fiber and lower fat mediated the relationship between the intervention and children's intake of varieties of vegetables. Mothers' percent energy from fat and behavioral strategies to lower fat were mediators of children's daily servings of sugar sweetened beverages. CONCLUSIONS: This study suggests that a promotora-led family based intervention can provide mothers with skills to promote modest changes in children's diet. Examining the parent related mechanisms of change will inform future interventions on important targets for improving children's diet. TRIAL REGISTRATION: https://clinicaltrials.gov/ . NCT02441049 .

AB - BACKGROUND: Limited evidence suggests that inherited predisposing risk variants might affect the disease outcome. In this study, we analyzed the effect of genome wide association studies-identified breast cancer-risk single nucleotide polymorphisms on survival of early-stage breast cancer patients in a Chinese population. METHODS: This retrospective study investigated the relationship between 21 GWAS-identified breast cancer-risk single nucleotide polymorphisms and the outcome of 1177 early stage breast cancer patients with a long median follow up time of 174 months. Cox proportional hazards regression models were used to estimate the hazard ratios and their 95% confidence intervals. Primary endpoints were breast cancer special survival and overall survival while secondary endpoints were invasive disease free survival and distant disease free survival. RESULTS: Multivariate survival analysis showed only the rs2046210 GA genotype significantly decreased the risk of recurrence and death for early stage breast cancer. After grouping breast cancer subtypes, significantly reduced survival was associated with the variant alleles of rs9485372 for luminal A and rs4415084 for triple negative breast cancer. Importantly, all three single-nucleotide polymorphisms, rs889312, rs4951011 and rs9485372 had remarkable effects on survival of luminal B EBC, either individually or synergistically. Furthermore, statistically significant multiplicative interactions were found between rs4415084 and age at diagnosis and between rs3803662 and tumor grade. CONCLUSIONS: Our results demonstrate that breast cancer risk susceptibility loci identified by GWAS may influence the outcome of early stage breast cancer patients' depending on intrinsic tumor subtypes in Chinese women. PMID- 30285757 TI - Role of maternity waiting homes in the reduction of maternal death and stillbirth in developing countries and its contribution for maternal death reduction in Ethiopia: a systematic review and meta-analysis. AB - BACKGROUND: Every family expect to have a healthy mother and new born baby after pregnancy. Especially for parents, pregnancy is a time of great anticipation. Access to maternal and child health care insures safer pregnancy and its outcome. MWHs is one the strategy. The objective was to synthesize the best available evidence on effectiveness of maternity waiting homes on the reduction of maternal mortality and stillbirth in developing countries. METHODS: Before conducting this review non-occurrences of the same review is verified. To avoid introduction of bias because of errors, two independent reviewers appraised each article. Maternal death and stillbirth were the primary outcomes. Review Manager 5 were used to produce a random-effect meta-analysis. Grade Pro software were used to produce risk of bias summary and summary of findings. RESULT: In developing countries, maternity waiting homes users were 80% less likely to die than non users (OR = 0. 20, 95% CI [0.08, 0.49]) and there was 73% less occurrence of stillbirth among users (OR = 0.27, 95% CI [0.09, 0.82]). In Ethiopia, there was a 91% reduction of maternal death among maternity waiting homes users unlike non users (OR = 0.09, 95% CI [0.04, 0.19]) and it contributes to the reduction of 83% stillbirth unlike non-users (OR = 0.17, 95% CI [0.05, 0.58]). CONCLUSION: Maternity waiting home contributes more than 80% to the reduction of maternal death among users in developing countries and Ethiopia. Its contribution for reduction of stillbirth is good. More than 70% of stillbirth is reduced among the users of maternity waiting homes. In Ethiopia maternity waiting homes contributes to the reduction of more than two third of stillbirths. PMID- 30285758 TI - A longitudinal, multi-centre, superiority, randomized controlled trial of internet-based cognitive behavioural therapy (iCBT) versus treatment-as-usual (TAU) for negative experiences and posttraumatic stress following childbirth: the JUNO study protocol. AB - BACKGROUND: About one-third of women report their childbirth as traumatic and up to 10% have severe traumatic stress responses to birth. The prevalence of Posttraumatic stress disorder following childbirth (PTSD FC) is estimated to 3%. Women with PTSD FC report the same symptoms as other patients with PTSD following other types of trauma. The effect of psychological treatment for women with PTSD FC has only been studied in a few trials. Similarly, studies on treatment needs for women not diagnosed as having PTSD FC but who nevertheless face psychological problems are lacking. METHODS/DESIGN: Women who rate their overall birth experience as negative on a Likert scale, and/or had an immediate caesarean section and/or a major postpartum haemorrhage are randomized to either internet delivered cognitive behaviour therapy (iCBT) plus treatment as usual (TAU) or TAU. The iCBT is to be delivered in two steps. The first step consists of six weekly modules for both the woman and her partner (if they wish to participate) with minimal therapeutic support. Step 2 consists of eight weekly modules with extended therapeutic support and will be offered to participants whom after step 1 report PTSD FC. Assessments will be made at baseline, 6 weeks, 14 weeks, and at follow-ups at 1, 2, 3 and 4 years after baseline. The primary outcome measures are symptoms of posttraumatic stress and depression. Secondary outcomes are quality of life, parent-child bonding, marital satisfaction, coping strategies, experience regarding the quality of care received, health-related quality of life, number of re-visits to the clinic and number of appointments for counselling during the 4 years' period after the negative childbirth experience, time until the woman gets pregnant again, and the type of birth in the subsequent pregnancy. A health economic evaluation in the form of a cost utility analysis will be conducted. DISCUSSION: This study protocol describes a randomized controlled trial that will provide information about the effectiveness of iCBT in women with negative experiences, posttraumatic stress, and PTSD FC.

PMID- 30285760 TI - Genomics of drug sensitivity in bladder cancer: an integrated resource for pharmacogenomic analysis in bladder cancer. AB - BACKGROUND: Bladder cancer has numerous genomic features that are potentially actionable by targeted agents. Nevertheless, both pre-clinical and clinical research using molecular targeted agents have been very limited in bladder cancer. RESULTS: We created the Genomics of Drug Sensitivity in Bladder Cancer (GDBC) database, an integrated database (DB) to facilitate the genomic understanding of bladder cancer in relation to drug sensitivity, in order to promote potential therapeutic applications of targeted agents in bladder cancer treatment. The GDBC database contains two separate datasets: 1) in-house drug sensitivity data, in which 13 targeted agents were tested against 10 bladder cancer cell lines; 2) data extracted and integrated from public databases, including the Cancer Therapeutics Research Portal, Cancer Cell Line Encyclopedia, Genomics of Drug Sensitivity in Cancer, Kyoto Encyclopedia of Genes and Genomes, and the Cancer Gene Census databases, as well as bladder cancer genomics data and synthetic lethality/synthetic dosage lethality connections. CONCLUSIONS: GDBC is an integrated DB of genomics and drug sensitivity data with a specific focus on bladder cancer. With a user-friendly web-interface, GDBC helps users generate genomics-based hypotheses that can be tested experimentally using drugs and cell lines included in GDBC. PMID- 30285761 TI - Case report: multiple UGT1A1 gene variants in a patient with Crigler-Najjar syndrome. AB - BACKGROUND: Inherited unconjugated hyperbilirubinemia is caused by variants in the gene UGT1A1 leading to Gilbert's syndrome and Crigler-Najjar syndrome types I and II. These syndromes are differentiated on the basis of UGT1A1 residual enzymatic activity and its affected bilirubin levels and responsiveness to phenobarbital treatment. CASE PRESENTATION: In this report, we present a boy with Crigler-Najjar syndrome type II with high unconjugated bilirubin levels that decreased after phenobarbital treatment but increased in adolescence. Four different UGT1A1 gene variants have been identified for this patient, of which one is novel (g.11895_11898del) most likely confirming diagnose molecularly. CONCLUSIONS: The presented case highlights the challenges encountered with the interpretation of molecular data upon identification of multiple variants in one gene that are causing different degree reducing effect on enzyme activity leading to several clinical conditions. PMID- 30285759 TI - Molecular characterization of three novel perforins in common carp (Cyprinus carpio L.) and their expression patterns during larvae ontogeny and in response to immune challenges. AB - BACKGROUND: In the host immune system, perforin is a cytotoxic effector molecule that eliminate virus-infected and malignant cells. Moreover, some recent studies also imply the involvement of perforin in antibacterial immunity. Common carp (Cyprinus carpio L.), one of the most economically important fish species in China, has a high susceptibility to viruses and bacteria. Thus far, in common carp, no data are available regarding the identification and immunologic function of the perforin. RESULTS: In the present study, the cDNA and genomic DNA sequences of three perforin isoform genes were cloned and characterized in common carp, named CcPRF1, CcPRF2 and CcPRF3. Amino acid sequences of the three CcPRFs were quite different, with identities ranged from 37.3 to 39.5%. Phylogenetic analysis showed that three CcPRFs, each in a separate sub-branch, possessed closer evolutionary relationship with other teleost perforins, especially with cyprinid fishes, than higher vertebrates. Expression analysis revealed that each CcPRF gene was differentially expressed in all of the nine tested tissues. During larvae ontogeny, each CcPRF displayed a distinct expression pattern, while with a common expression peak at 22 days post hatching (dph). Moreover, in vivo or in vitro, after stimulation with polyI:C, LPS and Aeromonas hydrophila, each CcPRF was induced significantly, with differential expression dynamics. CONCLUSIONS: Our findings suggest that perforin might play significant roles in larval immune system and in the immune defense of common carp against viral and bacterial pathogens. Meantime, the differential expression dynamics seem to imply possible different cellular locations or functional differences across various CcPRF isoforms. PMID- 30285762 TI - Echocardiographic markers of dyssynchrony as predictors of super-response to cardiac resynchronisation therapy - a pilot study. AB - BACKGROUND: Some patients with congestive heart failure have greater improvement of cardiac remodelling after cardiac resynchronisation therapy (CRT) and they are identified as super-responders (SRs). It remains unclear if echocardiographic markers of dyssynchrony could accuratelly predict super-response to CRT. The aim of this study is to evaluate potential echocardiographic predictors associated with super-response to CRT. METHODS: Fifthy nine CRT patients (mean age 52.9 +/- 9.0 years, 88% men) with congestive heart failure (54% ischaemic and 46% non ischaemic aetiology) II-IV NYHA functional class were enrolled. To assess mechanical dyssynchrony we evaluated interventricular mechanical delay, the maximum delay between peak systolic velocities of the septal and posterior walls of left ventricle, duration of left ventricular pre-ejection period (LVPEP), left ventricular and interventricular dyssynchrony by tissue Doppler imaging and systolic dyssynchrony index by 3D echocardiography. After six months the patients were assessed for response and classified as SRs (reduction in left ventricular end-systolic volume (LVESV) >=30%, n = 20) and non-SRs (reduction in LVESV < 30%, n = 39) and baseline data were analyzed to identify the predictors. RESULTS: Both groups demonstrated significant improvement in NYHA functional class, increase in left ventricular ejection fraction and reduction in LVESV. All parameters of mechanical dyssynchrony at baseline were significantly higher in SR group. Multiple logistic regression analysis showed that LVPEP (HR 1.031; 95% CI 1.007 1.055; p = 0.011) was an independent predictor for CRT super-response. In ROC curve analysis LVPEP with a cut-off value of 147 ms demonstrated 73.7% sensitivity and 75% specificity (AUC = 0.753; p = 0.002) for the prediction of super-response to CRT. CONCLUSION: Greater mechanical dyssynchrony is associated with super-response to CRT in patients with congestive heart failure. It is probable that an LVPEP > 147 ms can be used as independent predictor of super response. PMID- 30285763 TI - Engrailed-2 (EN2) - a novel biomarker in epithelial ovarian cancer. AB - BACKGROUND: Epithelial ovarian cancer is a common malignancy, with no clinically approved diagnostic biomarker. Engrailed-2 (EN2) is a homeodomain-containing transcription factor, essential during embryological neural development, which is dysregulated in several cancer types. We evaluated the expression of EN2 in Epithelial ovarian cancer, and reviewed its role as a biomarker. METHODS: We evaluated 8 Epithelial ovarian cancer cell lines, along with > 100 surgical specimens from the Royal Surrey County Hospital (2009-2014). In total, 108 tumours and 5 normal tissue specimens were collected. En2 mRNA was evaluated by semi-quantitative RT-PCR. Histological sub-type, and platinum-sensitive/ resistant status were compared. Protein expression was assessed in cell lines (immunofluorescence), and in > 150 tumours (immunohistochemistry). RESULTS: En2 mRNA expression was elevated in serous ovarian tumours compared with normal ovary (p < 0.001), particularly in high-grade serous ovarian cancer (p < 0.0001) and in platinum-resistant tumours (p = 0.0232). Median Overall Survival and Progression free Survival were reduced with high En2 expression (OS = 28 vs 42 months, p = 0.0329; PFS = 8 vs 27 months; p = 0.0004). Positive cytoplasmic EN2 staining was demonstrated in 78% of Epithelial ovarian cancers, with absence in normal ovary. EN2 positive high-grade serous ovarian cancer patients had a shorter PFS (10 vs 17.5 months; p = 0.0103). CONCLUSION: The EN2 transcription factor is a novel ovarian cancer biomarker. It demonstrates prognostic value, correlating with worse Overall Survival and Progression-free Survival. It is hoped that further work will validate its use as a biomarker, and provide insight into the role of EN2 in the development, progression and spread of ovarian cancer. PMID- 30285764 TI - Reduced menin expression impairs rapamycin effects as evidenced by an increase in mTORC2 signaling and cell migration. AB - BACKGROUND: Mammalian target of rapamycin (mTOR) is a master regulator of various cellular responses by forming two functional complexes, mTORC1 and mTORC2. mTOR signaling is frequently dysregulated in pancreatic neuroendocrine tumors (PNETs). mTOR inhibitors have been used in attempts to treat these lesions, and prolonged progression free survival has been recorded. If this holds true also for the multiple endocrine neoplasia type 1 (MEN1) associated PNETs is yet unclear. We investigated the relationship between expression of the MEN1 protein menin and mTOR signaling in the presence or absence of the mTOR inhibitor rapamycin. METHODS: In addition to use of menin wild type and menin-null mouse embryonic fibroblasts (MEFs), menin was silenced by siRNA in pancreatic neuroendocrine tumor cell line BON-1. Panels of protein phosphorylation, as activation markers downstream of PI3k-mTOR-Akt pathways, as well as menin expression were evaluated by immunoblotting. The impact of menin expression in the presence and absence of rapamycin was determinate upon Wound healing, migration and proliferation in MEFs and BON1 cells. RESULTS: PDGF-BB markedly increased phosphorylation of mTORC2 substrate Akt, at serine 473 (S473) and threonine 450 (T450) in menin-/- MEFs but did not alter phosphorylation of mTORC1 substrates ribosomal protein S6 or eIF4B. Acute rapamycin treatment by mTORC1-S6 inhibition caused a greater enhancement of Akt phosphorylation on S473 in menin-/- cells as compared to menin+/+ MEFs (116% vs 38%). Chronic rapamycin treatment, which inhibits both mTORC1and 2, reduced Akt phosphorylation of S473 to a lesser extent in menin-/- MEFs than menin+/+ MEFs (25% vs 75%). Silencing of menin expression in human PNET cell line (BON1) also enhanced Akt phosphorylation at S473, but not activation of mTORC1. Interestingly, silencing menin in BON1 cells elevated S473 phosphorylation of Akt in both acute and chronic treatments with rapamycin. Finally, we show that the inhibitory effect of rapamycin on serum mediated wound healing and cell migration is impaired in menin-/- MEFs, as well as in menin-silenced BON1 cells. CONCLUSIONS: Menin is involved in regulatory mechanism between the two mTOR complexes, and its reduced expression is accompanied with increased mTORC2-Akt signaling, which consequently impairs anti-migratory effect of rapamycin. PMID- 30285765 TI - Combining multi-scale composite windows with hierarchical smoothing strategy for fingerprint orientation field computation. AB - BACKGROUND: Orientation field (OF) plays a very significant role in automatic fingerprint recognition systems. Many algorithms have been proposed for the estimation of fingerprints' OF but it is hard to solve the dilemma of correcting spurious ridge structure and avoiding singularity location deviation, especially for poor images. So far, the following drawbacks still need to be solved for OF construction methods for practical application: (1) How to adaptively choose block scales to resolve the contradiction between accuracy and anti-noise, since small scale is beneficial to accuracy but is sensitive to noise, while large scale is more resistant to noise, but the accuracy is deteriorated. (2) How to construct the genuine OF in the areas close-by singular points and to evade singularity location deviation? Current block based methods give spurious OF estimates in the area near singular points because these areas have large curvature thus the detected singular points deviate from the genuine localizations. When these singular points are used as the anchor for referencing minutiae, it makes the average error of matching or recognition even larger. Therefore, it is essentials to construct the genuine OF in the areas close-by singular points and to evade singularity deviation. METHODS: To overcome the above-mentioned limitations, a novel method, combining a weighted multi-scale composite window (WMCM) with a hierarchical smoothing strategy has been proposed for the computation of fingerprint OF. This method mainly contains two procedures: the approximate OF estimation and the hierarchical OF smoothing. In the first procedure, a series of OFs are established under multiple scales of composite windows by using a gradient based method then a coarse OF is estimated using the weight of each scale determined by a squared gradient consistency. In the second procedure, the OF is first quantized into a two-digitized orientation zone and a two-orientation-zone filtering strategy is adapted to the OF blocks based on a filtering mask obtained after eliminating the isolated blocks. In the end a similar three-digitized orientation zone is performed to obtain an accurate and smooth OF. To validate the performance, the proposed method has been applied to OF computation using the FVC2004 databases and three experiments are designed. Experiment 1 aims to validate whether the weighted multi-scale composite window can balance the dilemma of accuracy and robustness more effectively than the previous works do. Experiment 2 is designed to examine whether the hierarchical smoothing method can correct the spurious ridge flow and preserve the genuine localization of singular points. The purpose of experiment 3 is to test the performance of the proposed method on OF reconstruction in low quality fingerprint images. The fingerprint databases FVC 2004 DB1-DB4 are employed in this study. RESULTS: The results of experiment I shows that the proposed method is capable to extract the information of OF reliably and it is more robust against singularity localization deviation in comparison with the other three gradient based methods. The results of experiment II indicates that the proposed smoothing method can balance the contradiction in correcting spurious ridge structures and preserving genuine singularity localization. The results of experiment III illustrates that our approach combing WMCW with the hierarchical smoothing method is capable to extract the information of OF ridge reliably and it is more robust against singularity deviation in comparison with the other three gradient based methods. In a word, the experiment results demonstrate that the proposed method can correct spurious ridge structure and meanwhile avoid singularity deviation compared with the previous works. CONCLUSIONS: A novel gradient based algorithm has been proposed which is more reliable for the estimation of the ridge information for fingerprint OF and is more accurate in preserving the singularity localization. Compared with the previously proposed gradient based methods, the advantages of the proposed RBSF lie in three aspects. Firstly a weighted multi-scale composite window is put forward to replace the single window used by conventional gradient based methods and to adaptively choose the scales of the blocks. Secondly, a hierarchical smoothing strategy is proposed to enhance the OF by using the two-orientation-zone filtering and the three-orientation-zone filtering, aiming to correct the spurious ridges and preserving the genuine location of singular points. Finally, three experiments are designed to test the proposed algorithm together with other popular gradient based methods on real fingerprint images, which are selected from different categories and all are suffering from obvious noise effects. All the experiment results show that the proposed method is superior with respect to reliable OF construction and avoiding singularity localization deviation. PMID- 30285766 TI - Conceptualising production, productivity and technology in pharmacy practice: a novel framework for policy, education and research. AB - CONTEXT AND BACKGROUND: People and health systems worldwide face serious challenges due to shifting disease demographics, rising population demands and weaknesses in healthcare provision, including capacity shortages and lack of impact of healthcare services. These multiple challenges, linked with the global push to achieve universal health coverage, have made apparent the importance of investing in workforce development to improve population health and economic well being. In relation to medicines, health systems face challenges in terms of access to needed medicines, optimising medicines use and reducing risk. In 2017, the International Pharmaceutical Federation (FIP) published global policy on workforce development ('the Nanjing Statements') that describe an envisioned future for professional education and training. The documents make clear that expanding the pharmacy workforce benefits patients, and continually improving education and training produces better clinical outcomes. AIMS AND PURPOSE: The opportunities for harnessing new technologies in pharmacy practice have been relatively ignored. This paper presents a conceptual framework for analysing production methods, productivity and technology in pharmacy practice that differentiates between dispensing and pharmaceutical care services. We outline a framework that may be employed to study the relationship between pharmacy practice and productivity, shaped by educational and technological inputs. METHOD AND RESULTS: The analysis is performed from the point of view of health systems economics. In relation to pharmaceutical care (patient-oriented practice), pharmacists are service providers; however, their primary purpose is not to deliver consultations, but to maximise the quantum of health gain they secure. Our analysis demonstrates that 'technology shock' is clearly beneficial compared with orthodox notions of productivity or incremental gain implementations. Additionally, the whole process of providing professional services using 'pharmaceutical care technologies' is governed by local institutional frames, suggesting that activities may be structured differently in different places and countries. DISCUSSION AND CONCLUSION: Addressing problems with medication use with the development of a pharmaceutical workforce that is sufficient in quantity and competence is a long-term issue. As a result of this analysis, there emerges a challenge about the profession's relationship with existing and emerging technical innovations. Our novel framework is designed to facilitate policy, education and research by providing an analytical approach to service delivery. By using this approach, the profession could develop examples of good practice in both developed and developing countries worldwide. PMID- 30285767 TI - Rasch analysis of the Herth Hope Index in cancer patients. AB - BACKGROUND: The concept of hope has been measured using the Herth Hope Index (HHI) in different samples, but varying factor structures comprising different items from the HHI have been reported. Therefore, further testing with regard to the dimensionality of the instrument is recommended. Rasch modeling can be used to evaluate validity evidence of an instrument's underlying structure, to identify items with poor fit to the rest of the scale, and to identify items that perform inconsistently across groups. The aim of this study was to assess the HHI's psychometric properties in a sample of cancer patients using a Rasch model. Adult oncology outpatients (n = 167) with pain from bone metastasis were included, and medical records were reviewed for disease and treatment information. Patients completed the 12-item HHI, which measures various dimensions of hope using a 4-point Likert scale that ranges from 1 (strongly disagree) to 4 (strongly agree). The internal scale validity, person response validity, unidimensionality, and uniform differential item functioning were evaluated by applying a Rasch rating scale model. RESULTS: Five (42%) of the twelve items (#3, #4, #5, #6 and #7) did not meet the criterion set for item goodness-of-fit. After removing these 5 items, the resulting 7-item scale demonstrated acceptable item fit to the model, acceptable unidimensionality (52.6% of the variance explained), acceptable person goodness-of-fit, adequate separation, and no differential item function. CONCLUSION: A 7-item version of the HHI had better psychometric properties than the original 12-item version among patients with cancer-related pain.

PMID- 30285768 TI - Decision-making preceding induced abortion: a qualitative study of women's experiences in Kisumu, Kenya. AB - BACKGROUND: Unwanted pregnancies and unsafe abortions are prevalent in regions where women and adolescent girls have unmet contraceptive needs. Globally, about 25 million unsafe abortions take place every year. In countries with restrictive abortion laws, safe abortion care is not always accessible. In Kenya, the high unwanted pregnancy rate resulting in unsafe abortions is a serious public health issue. Gaps exist in knowledge regarding women's decision-making processes in relation to induced abortions in Kenya. Decision-making is a fundamental factor for consideration when planning and implementing contraceptive services. This study explored decision-making processes preceding induced abortion among women with unwanted pregnancy in Kisumu, Kenya. METHODS: Individual face-to-face in depth interviews were conducted with nine women aged 19-32 years old. Women who had experienced induced abortion were recruited after receiving post-abortion care at the Jaramogi Oginga Odinga Teaching and Referral Hospital (JOOTRH) or Kisumu East District Hospital (KDH) in Kisumu, Kenya. In total, 15 in-depth interviews using open-ended questions were conducted. All interviews were tape recorded, transcribed and coded manually using inductive content analysis. RESULTS: Respondents described their own experiences regarding decision-making preceding induced abortion. This study shows that the main reasons for induced abortion were socio-economic stress and a lack of support from the male partner. In addition, deviance from family expectations and gender-based norms highly influenced the decision to have an abortion among the interviewed women. The principal decision maker was often the male partner who pressed for the termination of the pregnancy indirectly by declining his financial or social responsibilities or directly by demanding termination. In some cases, the male partner controlled decision-making by arranging an unsafe abortion without the woman's consent. Strategic choices regarding whom to confide in were employed as protection against abortion stigma. This contributed to a culture of silence around abortion and unwanted pregnancy, a factor that made women more vulnerable to complications. CONCLUSIONS: The findings suggest that financial, social and gender-based dependencies influence women's agency and perceived options in decision-making regarding abortion. PMID- 30285770 TI - Efficacy of anti-PD-1/PD-L1 antibodies after discontinuation due to adverse events in non-small cell lung cancer patients (HANSHIN 0316). AB - BACKGROUND: Immune checkpoint inhibitors (ICIs) have emerged as promising therapeutic agents in non-small cell lung cancer (NSCLC). However, the duration for which ICIs should be continued remains a clinical problem. METHODS: We examined the efficacy of anti-PD-1/PD-L1 inhibitors after the discontinuation of antibodies due to adverse events (AEs) in patients with NSCLC. This was a multicenter retrospective study that analyzed NSCLC patients who were treated with PD-1/PD-L1 inhibitors by August 2016. RESULTS: The patients with NSCLC were 18 males and 1 female at a median 67 years of age (range: 49-80 years). Eighteen of 19 patients were treated with nivolumab, one was with atezolizumab. Approximately half of AEs were interstitial pneumonia. Fourteen patients (73.7%) were treated with steroid therapy. The median number of treatment cycles was 7 (range, 1-70), and the median duration of treatment was 2.8 months (range, 1 day 32.9 months). The overall response rate with confirmation during treatment was 21.1%. The median progression-free survival (PFS) was 10.2 months (95% confidence interval [CI] = 3.2-17.1 months) and 5.6 months (95% CI = 0-12.2 months) from the initiation and the discontinuation of PD-1/PD-L1 treatment, respectively. The median PFS after discontinuation according to the confirmed response during administration was not reached for partial response (PR) and 4.9 months (95% CI, 3.7-6.0) for stable disease (SD) patients (P = 0.02). CONCLUSION: The PFS of the PR patients was completely different from that of the SD patients. The cases with PR prior to the onset of AE tended to show a durable response after the discontinuation of PD-1/PD-L1 inhibitors. PMID- 30285769 TI - Adeno-associated virus gene delivery of broadly neutralizing antibodies as prevention and therapy against HIV-1. AB - Vectored gene delivery of HIV-1 broadly neutralizing antibodies (bNAbs) using recombinant adeno-associated virus (rAAV) is a promising alternative to conventional vaccines for preventing new HIV-1 infections and for therapeutically suppressing established HIV-1 infections. Passive infusion of single bNAbs has already shown promise in initial clinical trials to temporarily decrease HIV-1 load in viremic patients, and to delay viral rebound from latent reservoirs in suppressed patients during analytical treatment interruptions of antiretroviral therapy. Long-term, continuous, systemic expression of such bNAbs could be achieved with a single injection of rAAV encoding antibody genes into muscle tissue, which would bypass the challenges of eliciting such bNAbs through traditional vaccination in naive patients, and of life-long repeated passive transfers of such biologics for therapy. rAAV delivery of single bNAbs has already demonstrated protection from repeated HIV-1 vaginal challenge in humanized mouse models, and phase I clinical trials of this approach are underway. Selection of which individual, or combination of, bNAbs to deliver to counter pre-existing resistance and the rise of escape mutations in the virus remains a challenge, and such choices may differ depending on use of this technology for prevention versus therapy. PMID- 30285771 TI - Exosome-transmitted long non-coding RNA PTENP1 suppresses bladder cancer progression. AB - BACKGROUND: Extracellular communication within the tumor microenvironment plays a critical role in tumor progression. Although exosomes can package into long non coding RNAs (lncRNAs) to mediate extracellular communication, the role of exosomal lncRNA PTENP1 in bladder cancer (BC) remains unclear. METHOD: We detected PTENP1 expression between patients with BC and healthy controls; the expression occurred in tissues and exosomes from plasma. We assessed the diagnostic accuracy by the receiver operating characteristic curve (ROC) and the area under curve (AUC). Cell phenotypes and animal experiments were performed to determine the effect of exosomal PTENP1. RESULTS: PTENP1 was significantly reduced in BC tissues and in exosomes from plasma of patients with BC (P < 0.05). We found that PTENP1 was mainly wrapped by exosomes. Exosomal PTENP1 could distinguish patients with BC from healthy controls (AUC = 0.743; 95% confidence interval (CI) = 0.645-0.840). Normal cells secreted exosomal PTENP1 and transmitted it to BC cells, thus inhibiting the biological malignant behavior of BC cells by increasing cell apoptosis and reducing the ability to invade and migrate (P < 0.05). Exosomal PTENP1 could suppress tumor growth in vivo. Furthermore, exosomal PTENP1 mediated the expression of PTEN by competitively binding to microRNA-17. CONCLUSION: Exosomal PTENP1 is a promising novel biomarker that can be used for the clinical detection of BC. Exosomes derived from normal cells transfer PTENP1 to BC cells, which reduce the progression of BC both in vitro and in vivo and suggest that exosomal PTENP1 participates in normal cell-to-bladder-cell communication during the carcinogenesis of BC. PMID- 30285772 TI - Availability of adequately iodized salt at household level in Dessie and Combolcha Towns, South Wollo, Ethiopia. AB - BACKGROUND: Iodine deficiency disorder is the leading cause of mental retardation and poor economic performance in developing countries. Worldwide, universal salt iodization has been implemented to eliminate iodine deficiency. However, the adequacy of iodine in salts needs close monitoring to meet its intended goal and this study was aimed at investigating the adequacy of iodine in dietary salt at household level in Dessie and Combolcha Towns. METHODS: A community-based cross sectional study was employed at household level in Dessie and Combolcha towns from January to February, 2017. Data were collected from 753 households using systematic sampling technique. The adequacy of iodine in salt was analyzed using rapid testing kit. Socio-demographic and economic, dietary sources, labeling, packaging, storage and cooking methods of household's characteristics were collected via questionnaire developed using open data kit tool and STATA version 12 was used for further statistical analysis. Ordinal Logistic regression was performed to assess associations between explanatory variables and the response variable. RESULTS: Nearly one-thrid (31.2%) of the households used inadequate iodized salt, which was below the World Health Organization recommendation level (>=15 ppm at the household level). Most of the respondents from Combolcha town (64.6%) were affected by inadequate use of iodized salt as compared to Dessie Town residents (22.2%). Being Dessie resident (OR = 2.53; 95% CI: 1.31-4.90), households with better socioeconomic status (OR = 2.54; 95% CI:1.10-5.87), site of labeling and packing (salt from open market (OR = 0.10; 95% CI: 0.04-0.23) and no exposure to sunlight (OR = 2.54; 95% CI:1.31-4.91) were the predictors of adequacy of iodized salt at household level. CONCLUSIONS: Availability of adequately iodized salt at the household level in the study area was low. There should be regular quality control and regulatory enforcement of salt iodization at production, labeling and packaging sites of small scale industries and at household level. PMID- 30285775 TI - Hospitalization for mental health related ambulatory care sensitive conditions: what are the trends for First Nations in British Columbia? AB - BACKGROUND: Indigenous peoples globally experience a disproportionate burden of mental illness due to forced policies and practices of colonization and cultural disruption. The objective of this study was to provide a baseline profile of hospitalization rates for mental health-related Ambulatory Care Sensitive Conditions among First-Nations living both on and off reserve in British Columbia, Canada, and explore the relationship between local access to health services and mental health-related hospitalization rates. METHODS: A population based time trend analysis of mental health-related Ambulatory Care Sensitive Conditions hospitalizations was conducted using de-identified administrative health data. The study population included all residents eligible under the universal British Columbia Medical Services Plan and living on and off First Nations reserves between 1994/95 and 2009/10. The definition of mental health related Ambulatory Care Sensitive Conditions included mood disorders and schizophrenia, and three different change measures were used to operationalize avoidable hospitalizations: 1) rates of episodes of hospital care, 2) rates of length of stay, and 3) readmission rates. Data were analyzed using generalized estimating equations approach, controlling for age, sex, and socio-economic status, to account for change over time. RESULTS: Our findings show that First Nations living on reserve have higher hospitalization rates for mental disorders compared to other British Columbia residents up until 2008. Those living off reserve had significantly higher hospitalization rates throughout the study period. On-reserve communities served by nursing stations had the lowest rates of hospitalization whereas communities with limited local services had the highest rates. Compared to other British Columbia residents, all First Nations have a shorter length of stay and lower readmission rates. CONCLUSIONS: This study suggests that despite reduced rates of hospitalization for mental-health related Ambulatory Care Sensitive Conditions over time for First Nations, gaps in mental health care still exist. We argue greater investments in primary mental health care are needed to support First Nations health. However, these efforts should place equal importance on prevention and the social determinants of health. PMID- 30285774 TI - The new clinical standard of integrated quadruple stress echocardiography with ABCD protocol. AB - BACKGROUND: The detection of regional wall motion abnormalities is the cornerstone of stress echocardiography. Today, stress echo shows increasing trends of utilization due to growing concerns for radiation risk, higher cost and stronger environmental impact of competing techniques. However, it has also limitations: underused ability to identify factors of clinical vulnerability outside coronary artery stenosis; operator-dependence; low positivity rate in contemporary populations; intermediate risk associated with a negative test; limited value of wall motion beyond coronary artery disease. Nevertheless, stress echo has potential to adapt to a changing environment and overcome its current limitations. INTEGRATED-QUADRUPLE STRESS-ECHO: Four parameters now converge conceptually, logistically, and methodologically in the Integrated Quadruple (IQ) stress echo. They are: 1- regional wall motion abnormalities; 2-B-lines measured by lung ultrasound; 3-left ventricular contractile reserve assessed as the stress/rest ratio of force (systolic arterial pressure by cuff sphygmomanometer/end-systolic volume from 2D); 4- coronary flow velocity reserve on left anterior descending coronary artery (with color-Doppler guided pulsed wave Doppler). IQ-Stress echo allows a synoptic functional assessment of epicardial coronary artery stenosis (wall motion), lung water (B-lines), myocardial function (left ventricular contractile reserve) and coronary small vessels (coronary flow velocity reserve in mid or distal left anterior descending artery). In "ABCD" protocol, A stands for Asynergy (ischemic vs non-ischemic heart); B for B-lines (wet vs dry lung); C for Contractile reserve (weak vs strong heart); D for Doppler flowmetry (warm vs cold heart, since the hyperemic blood flow increases the local temperature of the myocardium). From the technical (acquisition/analysis) viewpoint and required training, B-lines are the kindergarten, left ventricular contractile reserve the primary (for acquisition) and secondary (for analysis) school, wall motion the university, and coronary flow velocity reserve the PhD program of stress echo. CONCLUSION: Stress echo is changing. As an old landline telephone with only one function, yesterday stress echo used one sign (regional wall motion abnormalities) for one patient with coronary artery disease. As a versatile smart-phone with multiple applications, stress echo today uses many signs for different pathophysiological and clinical targets. Large scale effectiveness studies are now in progress in the Stress Echo2020 project with the omnivorous "ABCD" protocol. PMID- 30285777 TI - Intravesical migration of female urethral dilator: a case report of a new urologic emergency in the era of e-commerce. AB - BACKGROUND: The introduction of foreign bodies in the female urethra for auto erotic stimulation or in case of psychiatric disorders is not uncommon. The occurrence of intravesical migration of these objects makes it necessary to remove it shortly after insertion, since after long term permanence complications are likely to occurr. CASE PRESENTATION: A 47-year-old white female was referred at our Urology department for migration inside the bladder of a metallic urethral dilator used for sexual stimulation. An ultrasound study and an X-ray plate of the pelvis clearly visualized the presence of an object shaped like a rifle bullet located in the bladder. Twenty-four hours later, the patient reported its spontaneous emission through the urethra during micturition. This was confirmed by US and X-ray imaging. CONCLUSIONS: The retrieval of foreign objects introduced through body orifices with purpose of sexual gratification is a known urological expertise. Curiously, in the case reported, the patient was able to manipulate the object thus facilitating its correct orientation and passage outside the bladder during micturition. To the best of our knowledge this is the first case of documented spontaneous emission through the urethra of a sizable intravesical foreign body. Sexual gratification in females though the insertion of urethral dilators is a growing practice, as demonstrated by the broad proposal of such instruments on the web. Therefore, the occurrence of accidental intravesical displacement of such kind of foreign body is increasingly likely, and the Urologists must be aware of this possibility. PMID- 30285776 TI - Cell adhesion-related gene somatic mutations are enriched in aggressive papillary thyroid microcarcinomas. AB - BACKGROUND: Approximately half of the documented increases in differentiated thyroid carcinoma is due to identification of papillary thyroid microcarcinomas (PTMCs). Knowing whether PTMC is aggressive is required for proper treatment, but until now, there has been no method for assessing these traits and understanding the underlying mechanisms for aggressiveness. METHODS: We performed whole-exome sequencing of 16 PTMCs and matched normal thyroid tissues and GO/KEGG analysis to study genetic alterations and biological consequences associated with aggressive PTMCs, and then sequenced these genes using a next-generation gene-panel approach in an additional 70 PTMC samples including aggressive (n = 50) and non-aggressive (n = 20) groups. RESULTS: We identified 254 somatic mutations of 234 genes, for which 178 mutations in 168 genes were found in the aggressive group, and 76 mutations in 74 genes were found in the non-aggressive group. Several recurrent mutations in BRAF, VCAN, ALDH1L1, and MUC5B were identified, and many novel but infrequent mutations in other genes were also found. The aggressive cohort had more mutational burdens than the non-aggressive group (P = 0.004). Nonsynonymous mutations of 13 genes (MUC5B, TNN, SSPO, PPFIA1, PCDHGA2, ITGA8, ITGA4, DCHS1, CRNN, ROCK1, RELN, LAMC2, and AEBP1) were involved in cell adhesion, and these were only present in the aggressive group. Targeted sequencing of these genes revealed significant enrichment in the aggressive group (P = 0.000004). CONCLUSION: PTC may have evolved from PTMC due to sharing similar gene mutations, and the accumulation of such mutations promoted the aggressiveness of PTMC. Gene mutants associated with cell adhesion may be used to predict PTMC aggressiveness and allow more selective treatment. PMID- 30285773 TI - Chronic viral infections in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). AB - BACKGROUND AND MAIN TEXT: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex and controversial clinical condition without having established causative factors. Increasing numbers of cases during past decade have created awareness among patients as well as healthcare professionals. Chronic viral infection as a cause of ME/CFS has long been debated. However, lack of large studies involving well-designed patient groups and validated experimental set ups have hindered our knowledge about this disease. Moreover, recent developments regarding molecular mechanism of pathogenesis of various infectious agents cast doubts over validity of several of the past studies. CONCLUSIONS: This review aims to compile all the studies done so far to investigate various viral agents that could be associated with ME/CFS. Furthermore, we suggest strategies to better design future studies on the role of viral infections in ME/CFS. PMID- 30285778 TI - Molecular characterization of human adenovirus associated with acute respiratory infections in Cameroon from 2011 to 2014. AB - BACKGROUND: Human adenoviruses (HAdVs) cause a wide range of diseases worldwide, including respiratory infections. Studies on HAdV molecular epidemiology are limited in Cameroon. The purpose of this study is to document the different types HAdV circulating in Cameroon in children with acute respiratory infections. METHODS: Nasopharyngeal swabs were collected from 811 children under 15 years from 2011 to 2014. The HAdV detection was assessed by semi-quantitative generic PCR r-gene(r). The HAdV-positive samples were typed by amplification and sequencing of partial hexon gene and a real-time PCR. Demographic data were collected and analyzed. The infection and hospitalization risk factors were assessed thought the Chi-square test. RESULTS: A total of 137/220 HAdV-positive samples were amplified successfully. Six species of HAdV (Mastadenovirus A to F) were detected with B (108/220) and C (47/220) being the predominant strains. Hospitalization and age were significantly associated to HAdV-B and HAdV-C respectively. Phylogenetic analysis of HAdV-B3 virus (18) and B7 (5) shows a conserved and a significant temporal stability in relation to the reference sequence (99.1 to 100% of similarity). CONCLUSION: This study reported HAdV species and types detected in children with acute respiratory infections in Cameroon between September 2011 and July 2014. These results support further evaluation of the spatio-temporal circulation pattern of HAdV species and types in Cameroon. PMID- 30285779 TI - Ugandan providers' views on the acceptability of contraceptive self-injection for adolescents: a qualitative study. AB - BACKGROUND: Self-injection of subcutaneous depot medroxyprogesterone acetate may offer greater discretion and increase access to injectable contraception, particularly for those who face challenges accessing clinic services. In particular, unmarried adolescents often encounter stigma when seeking services, and may also lack the financial means to travel to clinics on the quarterly basis that injectable contraception requires. Whether self-injection is offered to women on a wide scale basis, and to adolescents specifically, will depend in part upon the willingness of providers to train clients of diverse ages and educational backgrounds. This study explores the views of providers with regard to self-injection as an option for women and adolescents in Uganda. METHODS: In depth qualitative interviews were conducted with family planning providers in Gulu district, to understand their views on injectable self-injection for women, with a specific focus on unmarried adolescents ages 15 to 19 years. The in-depth interviews, which lasted up to 60 min were audio-recorded, translated and transcribed simultaneously, and analyzed using Atlas.ti software to identify key themes and common perspectives. RESULTS: A total of 40 health care providers were interviewed with equal numbers of each type (public, NGO, and private clinics, pharmacies, and community-based health workers). While most providers were receptive to self-injection for adult women, fewer than half were supportive of adolescent self-injection. Their reservations focused on age, marital status and parity concerns around adolescent use of the injectable more broadly, and concerns about the ability of adolescents to self-inject safely. CONCLUSIONS: Self-injection presents an opportunity to reduce the enormous burden on the public sector health system in Uganda, which is particularly compounded by the heavy reliance on injectable contraception requiring quarterly clinic visits. The results of this study reveal a level of cautious support for self-injection among providers when it comes to self-injection by adult women. With respect to adolescent clients, family planning policymakers and program implementers should design, implement, and evaluate self-injection interventions with the needs of adolescent clients uppermost in mind, recognizing that extra attention will likely be needed to reduce provider-imposed restrictions on adolescent access to this injectable delivery modality. PMID- 30285780 TI - Robotic versus laparoscopic surgery for rectal cancer in male urogenital function preservation, a meta-analysis. AB - BACKGROUND: Urogenital dysfunction after rectal cancer surgery can largely affect patients' postoperative quality of life. Whether robotic surgery can be a better option when comparing with laparoscopic surgery is still not well-known. METHODS: Comprehensive search in PubMed, Embase, Cochrane Library, and Clinical Trials was conducted to identify relevant studies in March 2018. Studies comparing robotic surgery with laparoscopic surgery were included. Measurement of urogenital function was through the International Prostate Symptom Score and International Index of Erectile Function. RESULTS: Six studies with 386 patients in robotic group and 421 patients in laparoscopic group were finally included. Pooled analysis indicated that bladder function was better at 12 months in the robotic group after the procedures (mean difference, - 0.30, 95% CI, - 0.52 to - 0.08). No significant difference was found at 3 and 6 months postoperatively (mean difference, - 0.37, 95% CI, - 1.48 to 0.73; mean difference, - 1.21, 95% CI, - 2.69 to 0.28). Sexual function was better at 3 months in the robotic group after surgery (mean difference, - 3.28, 95% CI, - 6.08 to - 0.49) and not significantly different at 6 and 12 months. (mean difference, 3.78, 95% CI, - 7.37 to 14.93; mean difference, - 2.82, 95% CI, - 8.43 to 2.80). CONCLUSION: Robotic surgery may offer faster recovery in urogenital function compared to laparoscopic surgery for rectal cancer. PMID- 30285781 TI - Molecular pathological expression in malignant gliomas resected by fluorescein sodium-guiding under the YELLOW 560 nm surgical microscope filter. AB - BACKGROUND: This study aimed to analyze the relationship between molecular pathologic expression of GFAP and Ki-67 and fluorescence levels, and to provide molecular pathological basis for the removal of malignant gliomas (MG) by Fluorescein Sodium (FLS) navigation under the YELLOW 560 nm surgical microscope filter. METHODS: A retrospective analysis of clinical data of 18 MG cases confirmed by the postoperative pathology was performed. All cases were resected by FLS guiding under the YELLOW 560 nm filter. Hematoxylin-eosin (HE) staining, molecular pathology markers GFAP, and Ki-67 immunohistochemical staining of the specimens were performed. The relationship between fluorescence staining levels and GFAP positive rate, Ki-67 proliferation index, and WHO grades was studied. RESULTS: There were 69 pathological specimens with fluorescence levels of "bright" fluorescence (n = 32), "low" fluorescence (n = 18), and "no" fluorescence (n = 19). Immunohistochemical staining showed GFAP-positive expression in both tumor cells and normal glial cells. The staining levels of the specimens in the fluorescence regions were higher than that in the non fluorescence regions. GFAP expression was positive in 61 specimens and negative in 8 specimens. Comparison of Ki-67 proliferation index using chi-square test showed different fluorescence levels had different Ki-67 proliferation indexes (chi2 = 14.678, p = 0.005). With high proliferation index of specimens, fluorescence level was brighter. WHO grade had no correlation with fluorescence levels (chi2 = 3.531, p = 0.171). CONCLUSION: FLS-guided resection of MG is safe and effective. In the boundary area of MG, fluorescence levels and Ki-67 proliferation index showed correlation. FLS-guided resection achieved the function of "reducing tumor cell," thus reducing the proliferation index in the lesion area. PMID- 30285782 TI - Overview of literature on RMC and applications to Tanzania. AB - Respectful maternity care research in Tanzania continues to increase. This is an overview of the literature summarizing research based on the domains which comprise this quality of care indicator, ranging from exploratory and descriptive to quantitative measurements of birth perinatal outcomes when respectful interventions are made. The domains of respectful care are reflected in the seven Universal Rights of Childbearing Women but go further to implicate facility administrators and policy makers to provide supportive infrastructure to allay disrespect and abuse.The research methodologies continue to be problematic and several ethical cautions restrict how much control is possible. Similarly, the barriers to collecting accurate accounts in qualitative studies of disrespect require astute interviewing and observation techniques. The participatory community-based and the critical sociology and human rights frameworks appear to provide a good basis for both researcher and participants to identify problems and determine possible solutions to the multiple factors that contribute to disrespect and abuse. The work-life conditions of midwives in the Global South are plagued with poor infrastructure and significantly low resources which deters respectful care while decreasing retention of workers. Researchers and policy makers have addressed disrespectful care by building human resource capacity, by strengthening professional organizations and by educating midwives in low resource countries. Furthermore, researchers encourage midwives not only to acquire attitudinal change and to adopt respectful maternity care skills, but also to emerge as leaders and change agents.Safe methods for conducting care while addressing low resources, skilled management of conflict and creative innovations to engage the community are all interventions that are being considered for quality improvement research. Tanzania is poised to evaluate the outcomes of education workshops that address all seven domains of respectful care. PMID- 30285783 TI - The relationship between physical literacy scores and adherence to Canadian physical activity and sedentary behaviour guidelines. AB - BACKGROUND: Physical literacy is an emerging construct in children's health promotion, and may impact their lifelong physical activity habits. However, recent data reveal that only a small portion of Canadian children are regularly physically active and/or meet sedentary behaviour guidelines. To our knowledge, no study has investigated the association between physical literacy and movement behaviour guidelines. Therefore, the purpose of this study was to examine the relationship between physical literacy scores in Canadian children who meet or do not meet physical activity and sedentary behaviour guidelines. METHODS: Children (n = 2956; 56.6% girls) aged 8-12 years from 10 Canadian cities had their physical literacy levels measured using the Canadian Assessment of Physical Literacy, which consists of four domains (Physical Competence; Daily Behaviour; Knowledge and Understanding; and Motivation and Confidence) that are aggregated to provide a composite physical literacy score. Physical activity levels were measured by pedometers, and sedentary behaviour was assessed through self-report questionnaire. Analyses were conducted separately for each guideline, comparing participants meeting versus those not meeting the guidelines. Comparisons were performed using MANOVA and logistic regression to control for age, gender, and seasonality. RESULTS: Participants meeting physical activity guidelines or sedentary behaviour guidelines had higher physical literacy domain scores for Physical Competence and for Motivation and Confidence compared to those not meeting either guideline (both p < 0.0001). Participants had increased odds of meeting physical activity guidelines and sedentary behaviour guidelines if they met the minimum recommended level of the Physical Competence and Motivation and Confidence domains. Significant age (OR 0.9; 95% CI: 0.8, 0.9), gender (OR 0.4; 95% CI: 0.3, 0.5) and seasonality effects (OR 1.6; 95% CI: 1.2, 2.2 spring and OR 1.7; 95% CI: 1.2, 2.5 summer, reference winter) were seen for physical activity guidelines, and age (OR 0.8; 95% CI: 0.7, 0.8) and gender effects (OR 1.7; 95% CI: 1.4, 2.0) for sedentary behaviour guidelines. Knowledge and Understanding of physical activity principles was not related to guideline adherence in either model. CONCLUSIONS: These cross-sectional findings demonstrate important associations between physical literacy and guideline adherence for physical activity and sedentary behaviour. Future research should explore the causality of these associations. PMID- 30285784 TI - Influence of the relative age effect on children's scores obtained from the Canadian assessment of physical literacy. AB - BACKGROUND: Age grouping by the imposition of a cut-off date, common in sports and education, promotes a relative age difference that is associated with developmental advantages for children who are born on the "early side" of the cut off date and disadvantages to those born later in the same year, which is known as the relative age effect (RAE) bias. Acquiring an adequate level of physical literacy is important for children to remain active for life. The Canadian Assessment of Physical Literacy (CAPL) is an assessment protocol that encompasses measures in the domains of children's Daily Behaviours, Physical Competence, Motivation and Confidence, and Knowledge and Understanding. The purpose of this study was to ascertain whether the CAPL scores were susceptible to the RAE, which could affect our interpretation of the CAPL findings. METHODS: This cross sectional study examined if scores obtained in the CAPL (i.e., the four domains individually and the total CAPL score) were susceptible to the RAE in children aged 8 to 12 years and, if so, which physical competence assessments (movement skills, cardiorespiratory, strength, muscular endurance, flexibility, and body composition measurements) were more susceptible. Participants (n = 8233, 49.8% boys) from the Royal Bank of Canada-CAPL Learn to Play project from 11 sites in seven Canadian provinces were tested using the CAPL protocol. RESULTS: Among boys and girls, the RAE was significantly associated with two and three of the four domain scores, respectively, after controlling for covariates. However, effect sizes were negligible for the comparisons between quarters of the year and physical literacy domains and overall scores. For the main effect of the relative age, boys and girls born in the first three months of the year were taller (F(3, 4074) = 57.0, p < 0.001, f2 = 0.04 and F(3, 4107) = 58.4, p < 0.001, f2 = 0.04, respectively) and demonstrated greater muscular strength (F(3, 4037) = 29.2, p < 0.001, f2 = 0.02 and F(3, 4077) = 25.1, p < 0.001, f2 = 0.02, respectively) compared with those born later in the same year. CONCLUSIONS: Collectively, our results suggest that the RAE bias is mainly negligible with regard to the domain scores and overall CAPL scores in this large sample of children. PMID- 30285786 TI - Early-BYRD: alternative early pacing and defibrillation lead replacement avoiding venous puncture. AB - BACKGROUND: In cases of lead failure after implantation of pacemakers (PM) or implantable cardioverter defibrillators (ICD) early lead replacement may be challenging. Puncture of the subclavian vein bears possible complications such as pneumothorax, hematothorax, and damage of leads to be left in place. To avoid venous puncture PM or ICD leads were replaced using a flexible polypropylene sheath (Byrd-sheath). METHOD: From January 2010 through December 2017, 55 patients underwent early lead exchange avoiding venous puncture. Early lead exchange for this study was defined as a reintervention within 14 days after the initial lead implantation. The connector of the malfunctioning lead was cut off, and stabilized by a stiff stylet. After having cut off the plastic knob of the stylet, the lead was passed through the polypropylene sheath and the latter advanced into the subclavian vein with gentle rotational movements to gain access to the subclavian vein. After lead removal the polypropylene sheath was replaced by a peel away sheath a new lead inserted. RESULTS: Overall, 23 defibrillation leads and 34 pacing leads (16 right atrial leads, 17 right ventricular leads, and 1 left ventricular lead) were successfully explanted. Access to the subclavian vein was uneventful, and blood loss minimal. Radiation exposure and fluoroscopy time were also negligible. CONCLUSION: The Byrd-sheath technique proved to be safe and successful in providing vein access within 2 weeks after initial lead implantation using the previously implanted lead and thus avoiding puncture of the subclavian vein. PMID- 30285787 TI - Non-orthogonal one-step calibration method for robotized transcranial magnetic stimulation. AB - BACKGROUND: Robotized transcranial magnetic stimulation (TMS) combines the benefits of neuro-navigation with automation and provides a precision brain stimulation method. Since the coil will normally remain unmounted between different clinical uses, hand/eye calibration and coil calibration are required before each experiment. Today, these two steps are still separate: hand/eye calibration is performed using methods proposed by Tsai/Lenz or Floris Ernst, and then the coil calibration is carried out based on the traditional TMS experimental step. The process is complex and time-consuming, and traditional coil calibration using a handheld probe is susceptible to greater calibration error. METHODS: A novel one-step calibration method has been developed to confirm hand/eye and coil calibration results by formulating a matrix equation system and estimating its solution. Hand/eye calibration and coil calibration are performed to confirm the pose relationships of the marker/end effector 'X', probe/end effector 'Y', and robot/world 'Z'. First, the coil is fixed on the end effector of the robot. During the one-step calibration process, a marker is mounted on the top of the coil and a calibration probe is fixed at the actual effective position of the coil. Next, the robot end effector is moved to a series of random positions 'A', the tracking data of marker 'B' and probe 'C' is obtained correspondingly. Then, a matrix equation system AX = ZB and AY = ZC can be acquired, and it is computed using a least-squares approach. Finally, the calibration probe is removed after calibration, while the marker remains fixed to the coil during the TMS experiment. The methods were evaluated based on simulation data and on experimental data from an optical tracking device. We compared our methods with two classical methods: the QR24 method proposed by Floris Ernst and the handheld coil calibration method. RESULTS: The new methods outperform the QR24 method in the aspect of translational accuracy and performs similarly in the aspect of rotational accuracy, the total translational error decreased more than fifty percent. The new approach also outperforms traditional handheld coil calibration of navigated TMS systems, the total translational error decreased three- to fourfold, and the rotational error decreased six- to eightfold. Furthermore, the convergence speed is improved 16- to 27-fold for the new algorithms. CONCLUSION: These results suggest that the new method can be used for hand/eye and coil calibration of a robotized TMS system. Two complex steps can be simplified using a least-squares approach. PMID- 30285785 TI - Peripheral immune system in aging and Alzheimer's disease. AB - Alzheimer's disease (AD) represents an urgent public health mandate. AD is no longer considered a neural-centric disease; rather, a plethora of recent studies strongly implicate a critical role played by neuroinflammation in the pathogeneses of AD and other neurodegenerative conditions. A close functional connection between the immune system and central nervous system is increasingly recognized. In late-onset AD, aging represents the most significant risk factor. Here, from an immunological perspective, we summarize the prominent molecular and cellular changes in the periphery of aging individuals and AD patients. Moreover, we review the knowledge gained in the past several years that implicate specific arms of the peripheral immune system and other types of immune responses in modulating AD progression. Taken together, these findings collectively emphasize a dynamic role of a concert of brain-extrinsic, peripheral signals in the aging and degenerative processes in the CNS. We believe that a systematic view synthesizing the vast amounts of existing results will help guide the development of next-generation therapeutics and inform future directions of AD investigation. PMID- 30285788 TI - Bladder preservation approach versus radical cystectomy for high-grade non-muscle invasive bladder cancer: a meta-analysis of cohort studies. AB - BACKGROUND: High-grade non-muscle-invasive bladder cancer is superficial; nonetheless, it is an aggressive cancer. Proper management strategy selection following transurethral resection between bladder preservation (BP) and radical cystectomy (RC) could result in delayed or excessive treatment. Hence, selecting the optimal treatment modality remains controversial to date. METHODS: We searched MEDLINE, The Cochrane Library, EMBASE, China National Knowledge Infrastructure, and Wanfang database through 12 April 2018. Quality and publication bias were assessed using the Newcastle-Ottawa Scale and Begg's/Egger's test. We collected 2-year, 5-year, 10-year, and 15-year survival rate and hazard ratio (HR) for overall survival (OS), cancer-specific survival (CSS), and progression-free survival (PFS). Using the Review Manager 5.2 software, we used the odds ratio (OR) of specific years and HR for meta-analysis. Subgroup analysis was performed by the original tumor state, radical cystectomy timing, bladder preservation modality, and age. RESULTS: In total, 11 cohorts with 1735 patients were selected for the meta-analysis. All OR of OS supported BP as a better treatment option; however, all OR of PFS had no significant differences. As for CSS, only the 15-year OR reflected a statistical significance preferring RC. Subgroup analysis showed that BP is more appropriate for patients older than 65 and G3 tumor. Limited data demonstrated that late RC (> 3 months) is more effective compared to early RC (< 3 months) and intravesical Bacillus Calmette-Guerin was not statistically different from that of RC. The mixed BP modalities were significantly better compared to RC in OS and worse in CSS, with both having a very low evidence strength. CONCLUSIONS: BP is a superior treatment modality compare to RC, especially for older patients and T1G3 or lower grade tumors. However, the superior BP modality was unclear. Conversely, RC could be a better option for younger patients. More specifically, late RC may be more beneficial but had a very-low-level of evidence. Quality of life should be considered equal to survival outcome; hence, post-treatment follow-up needs to be performed. Prospective randomized studies should be performed to overcome the limitations of this meta-analysis study. REGISTRATION: Registration ID is CRD42018093491 . PMID- 30285790 TI - Lipid compositional changes and oxidation status of ultra-high temperature treated Milk. AB - BACKGROUND: Milk fat is one of the complex fat and most sensitive biochemical compounds towards auto-oxidation. To enhance the shelf life, milk is subjected to Ultra-high Temperature (UHT) treatment followed by aseptic packaging. During the storage, several chemical and biochemical changes take place in lipid fraction of UHT milk. In current investigation, the effect of UHT treatment and storage was determined by making a comparison in fatty acid profile, triglyceride composition, organic acids and lipid oxidation of the thermally treated and stored milk with raw milk, which was not reported in earlier investigations. METHODS: Raw milk samples were collected from the bulk storage facility of a dairy industry. The same milk was routed to UHT treatment and aseptically packaged samples were collected. The fatty acid profile, triglyceride composition, organic acids and lipid oxidation was determined in raw and UHT treated milk at 0, 30, 60 and 90 days. Fatty acid and triglyceride profile was determined on GC-MS while organic acids were determined by HPLC. For the measurement of induction period, professional Rancimat was used. Lipid oxidation was characterized through free fatty acids, peroxide value, anisidine value and conjugated dienes. RESULTS: Compositional attributes of milk remain unchanged during the entire length of storage. Concentrations of short-chain fatty acids in raw and UHT milk were 10.49% and 9.62%. UHT treatment resulted in 8.3% loss of short-chain fatty acids. Up to 30 days, storage did not have any significant effect on fatty acid profile of UHT milk. Concentration of medium-chain fatty acids in raw and UHT treated milk was 54.98% and 51.87%. After 30, 60 and 90 days of storage, concentration of medium chain fatty acids was found 51.23%, 47.23% and 42.82%, respectively. Concentration of C18:1 and C18:2 in raw and UHT milk was 26.86% and 25.43%, respectively. The loss of C18:1 and C18:2 in UHT treatment was 5.32%. After 30, 60 and 90 days of storage, the concentrations of C18:1 and C18:2 were 24.6%, 21.06% and 18.66%, respectively. Storage period of 30 days was found non-significant, while noticeable variations were found in triglyceride profile of 60 and 90 days old samples of UHT milk. UHT treatment and storage period significantly affected the concentration of organic acids in milk. After UHT treatment, concentration of lactic acid, acetic acid, citric acid, pyruvic acid, formic acid, succinic acid and oxalic acid increased by 3.45, 0.66, 3.57, 0.68, 2.24, 2.16 and 1.63 mg/100 g. Effect of storage period on the production of organic acids in UHT milk was non-significant up to 30 days. After 60 days of storage period, the increase in concentration of lactic acid, acetic acid, citric acid, pyruvic acid, formic acid, succinic acid and oxalic acid was 3.79, 0.75, 4.69, 0.78, 2.83, 3.03 and 2.38 mg/100 g. After 90 days of storage period, the increase in concentration of lactic acid, acetic acid, citric acid, pyruvic acid, formic acid, succinic acid and oxalic acid was 7.3, 2.18, 9.96, 3.58, 11.37, 5.22 and 5.96%. Free fatty acids content of raw, UHT treated and 90 days old milk were 0.08%, 0.11% and 0.19%. UHT treated version of milk showed similar peroxide value. While, the storage remarkably affected the peroxide value. After 30, 60 and 90 days, peroxide value was 0.42, 0.62 and 1.18 (MeqO2/kg). Induction period of raw, UHT and stored milk was strongly correlated with peroxide value and fatty acid profile. Mean value of lipase activity in raw milk was 0.73 +/- 0.06 MUmoles/ml. UHT treatment significantly decreased the lipase activity. The lipase activity of milk immediately after the UHT treatment was 0.18 +/- 0.02 MUmoles/ml. Lipase activity of UHT milk after 30, 60 and 90 days of room temperature storage was 0.44 +/- 0.03, 0.95 +/- 0.07 and 1.14 +/- 0.09 MUmoles/ml. Color, flavor and smell score decreased through the storage of UHT milk for 90 days. CONCLUSION: The results of this investigation revealed that fatty acid and triglyceride profile changed after 60 and 90 days of storage. Production of organic acids led to the drop of pH and sensory characteristics in UHT milk during the long-term storage. Induction period can be successfully used for the determination of anticipatory shelf life of UHT milk. PMID- 30285789 TI - Eating behavior and body composition across childhood: a prospective cohort study. AB - BACKGROUND: Although many cross-sectional studies reported that children with overweight or obesity show more food approaching and less food avoidant eating behaviors, there is a lack of replication in longitudinal studies. Therefore, the question remains whether healthcare professionals should target eating behaviors in childhood obesity interventions and prevention. We aimed to examine the longitudinal and possible bi-directional associations between eating behavior and body composition across childhood. METHODS: Data was included from 3331 children participating in the Generation R Study. At 4 and 10 years, mothers reported on the Child Eating Behavior Questionnaire including the subscales Food Responsiveness, Enjoyment of Food, Emotional Overeating and Satiety Responsiveness, and children's BMI was measured. Body composition, consisting of Fat Mass Index and Fat Free Mass Index was measured at 6 and 10 years with Dual energy-X-ray-Absorptiometry scans. RESULTS: Cross-lagged models including both directions of the BMI - eating behavior association showed that a higher BMI at the age of 4 years predicted more food responsiveness and enjoyment of food and less satiety responsiveness at 10 years (e.g. satiety responsiveness:beta = - 0.10, 95% CI = - 0.14, - 0.07), but no associations were found in the opposite direction. For emotional overeating, however, a bi-directional association was found with BMI predicting more emotional eating and vice versa. Multivariable linear regression analyses showed that associations were stronger for Fat Mass Index than for Fat Free Mass Index. CONCLUSIONS: Results showed that a higher BMI, and particularly higher fat mass, at pre-school age predicted more food approaching and less food avoidant eating behaviors at the age of 10 years, rather than the hypothesized reverse direction. This suggests that increased adiposity in early childhood might upregulate appetite and related eating behaviors. PMID- 30285792 TI - Efficacy of regional arterial embolization before pleuropulmonary resection in 32 patients with tuberculosis-destroyed lung. AB - BACKGROUND: Treatment of tuberculous-destroyed lung (TDL) with pleuropulmonary resection is challenging. Pulmonary hemorrhage is a frequent complication of this surgical procedure. Continuous efforts have been made to investigate clinical procedures that may reduce intraoperative bleeding effectively. In this study, we evaluated the feasibility and safety of regional arterial embolization before pleuropulmonary resection in patients with TDL. METHODS: The clinical data of 32 patients with TDL were retrospectively reviewed and analyzed. These patients were admitted to the hospital between July 2009 and November 2016. All of the patients had moderate to massive hemoptysis and received regional arterial embolization in affected areas. Then, these patients underwent pleuropulmonary resection within 1 week to 2 months after embolization. RESULTS: The results showed that 25 patients (78.1%) had bronchial artery, and all patients had non-bronchial systemic artery found in affected areas. Mild to moderate chest pain was reported in 6 patients, and fever was reported in 2 patients. Intraoperative blood loss during pleuropulmonary resection in patients who had received preoperative regional arterial embolization was 625.6 +/- 352.6 ml. Duration of the operation was 120.3 +/- 75.2 min. Bronchopleural fistulae and empyema were found in 3 cases (9.4%). CONCLUSION: Performance of regional arterial embolization before pleuropulmonary resection offers a safe and feasible option that reduces intraoperative blood loss and shortens operative time in patients with TDL. PMID- 30285791 TI - Molecular signature of response to preoperative radiotherapy in locally advanced breast cancer. AB - BACKGROUND: Radiation therapy is an indispensable part of various treatment modalities for breast cancer. Specifically, for non-inflammatory locally advanced breast cancer (LABC) patients, preoperative radiotherapy (pRT) is currently indicated as a second line therapy in the event of lack of response to neoadjuvant chemotherapy. Still approximately one third of patients fails to respond favourably to pRT. The aim of this study was to explore molecular mechanisms underlying differential response to radiotherapy (RT) to identify predictive biomarkers and potential targets for increasing radiosensitivity. METHODS: The study was based on a cohort of 134 LABC patients, treated at the Institute of Oncology and Radiology of Serbia (IORS) with pRT, without previous or concomitant systemic therapy. Baseline transcriptional profiles were established using Agilent 60 K microarray platform in a subset of 23 formalin fixed paraffin-embedded (FFPE) LABC tumour samples of which 11 radiotherapy naive and 3 post-radiotherapy samples passed quality control and were used for downstream analysis. Biological networks and signalling pathways underlying differential response to RT were identified using Ingenuity Pathways Analysis software. Predictive value of candidate genes in the preoperative setting was further validated by qRT-PCR in an independent subset of 60 LABC samples of which 42 had sufficient quality for data analysis, and in postoperative setting using microarray data from 344 node-negative breast cancer patients (Erasmus cohort, GSE2034 and GSE5327) treated either with surgery only (20%) or surgery with RT (80%). RESULTS: We identified 192 significantly differentially expressed genes (FDR < 0.10) between pRT-responsive and non-responsive tumours, related to regulation of cellular development, growth and proliferation, cell cycle control of chromosomal replication, glucose metabolism and NAD biosynthesis II route. APOA1, MAP3K4, and MMP14 genes were differentially expressed (FDR < 0.20) between pRT responders and non-responders in preoperative setting, while MAP3K4 was further validated as RT-specific predictive biomarker of distant metastasis free survival (HR = 2.54, [95%CI:1.42-4.55], p = 0.002) in the postoperative setting. CONCLUSIONS: This study pinpoints MAP3K4 as a putative biomarker of response to RT in both preoperative and postoperative settings and a potential target for radiosensitising combination therapy, warranting further pre-clinical studies and prospective clinical validation. PMID- 30285793 TI - Melanoma cell-secreted exosomal miR-155-5p induce proangiogenic switch of cancer associated fibroblasts via SOCS1/JAK2/STAT3 signaling pathway. AB - BACKGROUND: Cancer-associated fibroblasts (CAFs) have been widely reported to promote tumor angiogenesis. However, the underlying mechanisms of the proangiogenic switch of CAFs remain poorly understood. This study aims to clarify the mechanisms underlying the proangiogenic switch of CAFs. METHODS: NIH/3T3 cells were treated with B16 and B16F10-derived exosomes. Then the CAFs markers and proangiogenic factors were detected by RT-PCR and Western blot. CCK-8 assay, transwell migration assay, tube formation assay, and in vivo Matrigel plug assay were conducted to determine the proangiogenic capability of CAFs. Western blot and AG490 were used to investigate the role of Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling pathway in the proangiogenic switch of CAFs. Bioinformatics analysis, luciferase reporter assay, microRNA mimic and inhibitor, and xenograft models were used to investigate the role of mmu-miR-155-5p (miR-155) in the proangiogenic switch of CAFs. RESULTS: In this study, we show that melanoma cell-secreted exosomes can induce reprogramming of fibroblasts into CAFs and that exosomal miR-155 can trigger the proangiogenic switch of CAFs. Mechanistically exosomal miR-155 can be delivered into fibroblasts and promote the expression of proangiogenic factors, including vascular endothelial growth factor A (VEGFa), fibroblast growth factor 2 (FGF2), and matrix metalloproteinase 9 (MMP9), by directly targeting suppressor of cytokine signaling 1 (SOCS1). Downregulation of SOCS1 activates JAK2/STAT3 signaling pathway and elevates the expression levels of VEGFa, FGF2, and MMP9 in fibroblasts. Treatment with exosomes containing overexpressed miR-155 can promote angiogenesis, and the reduction of miR-155 in melanoma cell-secreted exosomes alleviates angiogenesis in vitro and in vivo. CONCLUSIONS: These results demonstrate that by promoting the expression of proangiogenic factors in recipient fibroblasts via SOCS1/JAK2/STAT3 signaling pathway, melanoma cell secreted exosomal miR-155 can induce the proangiogenic switch of CAFs. Although tumor angiogenesis is modulated by various factors, exosomal miR-155 may be a potential target for controlling melanoma angiogenesis and used to set up novel strategies to treat melanoma. PMID- 30285794 TI - Prosthesis-patient mismatch after mitral valve replacement: a single-centered retrospective analysis in East China. AB - BACKGROUND: Prosthesis-patient mismatch (PPM) may affect the clinical outcomes of patients undergoing mitral valve replacement (MVR) surgery. We aimed to investigate the incidence of PPM of the mitral position in our center and analyze the possible predictors of PPM as well as its effect on short-term outcomes. METHODS: We retrospectively examined all consecutive patients with isolated or concomitant MVR at our center from 2013 to 2015. PPM was defined as an indexed effective orifice area (iEOA) of <=1.2 cm2/m2. After inclusion and exclusion, a total of 1067 patients were analyzed. The baseline information were collected and compared between the two groups. Multivariate logistic regression analysis was conducted to determine the preoperative predictors of PPM as well as the effect of PPM on early mortality. RESULTS: A total of 1067 patients were included in the study. PPM was detected in 15.9% of the patients while 12 patients (1.12%) met the criteria for severe PPM. Patients with PPM compared to the non-PPM patients had higher age, larger body surface area and were more likely to be male and obese. Logistic regression analysis showed that higher age, larger BSA, bioprosthesis and smaller left ventricle end-diastolic diameter were predictors of PPM. There were no significant differences between the PPM and non-PPM groups regarding post-operative complications. Logistic regression analysis showed that PPM was not a risk factor of short-term mortality (P = 0.654). Also, there were no significant differences regarding short-/mid-term heart function between the PPM and non PPM groups (P = 0.902). CONCLUSIONS: Our results demonstrated that higher age, bioprosthesis, larger BSA and smaller left ventricle size were associated with mitral PPM. However, PPM was not associated with poorer early outcomes after MVR surgery. In eastern of China, the prevalence of mitral valve stenosis is high; therefore, whether the standard PPM criteria are suitable for patients of this district needs to be further verified. PMID- 30285795 TI - Percutaneous versus thoracoscopic ablation of symptomatic paroxysmal atrial fibrillation: a randomised controlled trial - the FAST II study. AB - BACKGROUND: The most efficient first-time invasive treatment, for achieving sinus rhythm, in symptomatic paroxysmal atrial fibrillation has not been established. We aimed to compare percutaneous catheter and video-assisted thoracoscopic pulmonary vein radiofrequency ablation in patients referred for first-time invasive treatment due to symptomatic paroxysmal atrial fibrillation. The primary outcome of interest was the prevalence of atrial fibrillation with and without anti-arrhythmic drugs at 12 months. METHODS: Ninety patients were planned to be randomised to either video-assisted thoracoscopic radiofrequency pulmonary vein ablation with concomitant left atrial appendage excision or percutaneous catheter pulmonary vein ablation. Episodes of atrial fibrillation were defined as more than 30 s of atrial fibrillation observed on Holter monitoring/telemetry or clinical episodes documented by ECG. RESULTS: The study was terminated prematurely due to a lack of eligible patients. Only 21 patients were randomised and treated according to the study protocol. Thoracoscopic pulmonary vein ablation was performed in 10 patients, and 11 patients were treated with catheter ablation. The absence of atrial fibrillation without the use of anti-arrhythmic drugs throughout the follow-up was observed in 70% of patients following thoracoscopic pulmonary vein ablation and 18% after catheter ablation (p < 0.03). CONCLUSION: Thoracoscopic pulmonary vein ablation may be superior to catheter ablation for first-time invasive treatment of symptomatic paroxysmal atrial fibrillation with regard to obtaining sinus rhythm off anti-arrhythmic drugs 12 months postoperative. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01336075 . Registered April 15th, 2011. PMID- 30285796 TI - Revising the motivation and confidence domain of the Canadian assessment of physical literacy. AB - BACKGROUND: The Motivation and Confidence domain questionnaire in the Canadian Assessment of Physical Literacy (CAPL) was lengthy (36 single items that aggregate to five subscales), and thus burdensome to both participants and practitioners. The purpose of this study was to use factor analysis to refine the Motivation and Confidence domain to be used in the CAPL-Second Edition (CAPL-2). METHODS: Children, primarily recruited through free-of-charge summer day camps (n = 205, Mage = 9.50 years, SD = 1.14, 50.7% girls), completed the CAPL-2 protocol, and two survey versions of the Motivation and Confidence questionnaire. Survey 1 contained the Motivation and Confidence questionnaire items from the original CAPL, whereas Survey 2 contained a battery of items informed by self determination theory to assess motivation and confidence. First, factor analyses were performed on individual questionnaires to examine validity evidence (i.e., internal structure) and score reliability (i.e., coefficient H and omega total). Second, factor analyses were performed on different combinations of questionnaires to establish the least burdensome yet well-fitted and theoretically aligned model. RESULTS: The assessment of adequacy and predilection, based on 16 single items as originally conceptualized within the CAPL, was not a good fit to the data. Therefore, a revised and shorter version of these scales was proposed, based on exploratory factor analysis. The self determination theory items provided a good fit to the data; however, identified, introjected, and external regulation had low score reliability. Overall, a model comprising three single items for each of the following subscales was proposed for use within the CAPL-2: adequacy, predilection, intrinsic motivation, and perceived competence satisfaction. This revised domain fit well within the overall CAPL-2 model specifying a higher-order physical literacy factor (MLRchi2(63) = 81.45, p = 0.06, CFI = 0.908, RMSEA = 0.038, 90% CI (0.00, 0.060)). CONCLUSIONS: The revised and much shorter questionnaire of 12 items that aggregate to four subscales within the domain of Motivation and Confidence is recommended for use in the CAPL-2. The revised domain is aligned with the definition of motivation and confidence within physical literacy and has clearer instructions for completion. PMID- 30285797 TI - An exploratory analysis of missing data from the Royal Bank of Canada (RBC) Learn to Play - Canadian Assessment of Physical Literacy (CAPL) project. AB - BACKGROUND: Physical literacy comprises a range of tests over four domains (Physical Competence, Daily Behaviour, Motivation and Confidence, and Knowledge and Understanding). The patterns of missing data in large field test batteries such as those for physical literacy are largely unknown. Therefore, the aim of this paper was to explore the patterns and possible reasons for missing data in the Royal Bank of Canada Learn to Play-Canadian Assessment of Physical Literacy (RBC Learn to Play-CAPL) project. METHODS: A total of 10,034 Canadian children aged 8 to 12 years participated in the RBC Learn to Play-CAPL project. A 32 variable subset from the larger CAPL dataset was used for these analyses. Several R packages ("Hmisc", "mice", "VIM") were used to generate matrices and plots of missing data, and to perform multiple imputations. RESULTS: Overall, the proportion of missing data for individual measures and domains ranged from 0.0 to 33.8%, with the average proportion of missing data being 4.0%. The largest proportion of missing data in CAPL was the pedometer step counts, followed by the components of the Physical Competence domain and the Children's Self-Perception of Adequacy in and Predilection for Physical Activity subscales. When domain scores were regressed on five imputed subsets with the original subset as the reference, there were small and statistically detectable differences in the Daily Behaviour score (beta = - 1.6 to - 1.7, p < 0.001). However, for the other domain scores the differences were negligible and statistically undetectable (beta = - 0.01 to - 0.06, p > 0.05). CONCLUSIONS: This study has implications for other researchers or educators who are creating or using large field-based assessment measures in the areas of physical literacy, physical activity, or physical fitness, as this study demonstrates where problems in data collection can arise and how missing data can be avoided. When large proportions of missing data are present, imputation techniques, correction factors, or other treatment options may be required. PMID- 30285799 TI - Identifying individuals with chronic pain after knee replacement: a population cohort, cluster-analysis of Oxford knee scores in 128,145 patients from the English National Health Service. AB - BACKGROUND: Approximately one in five patients undergoing knee replacement surgery experience chronic pain after their operation, which can negatively impact on their quality of life. In order to develop and evaluate interventions to improve the management of chronic post-surgical pain, we aimed to derive a cut off point in the Oxford Knee Score pain subscale to identify patients with chronic pain following knee replacement, and to characterise these patients using self-reported outcomes. METHODS: Data from the English Patient-Reported Outcome Measures (PROMs) programme were used. This comprised patient-reported data from 128,145 patients who underwent primary knee replacement surgery in England between 2012 and 2015. Cluster analysis was applied to derive a cut-off point on the pain subscale of the Oxford Knee Score. RESULTS: A high-pain group was identified, described by a maximum of 14 points in the Oxford Knee Score pain subscale six months after surgery. The high-pain group, comprising 15% of the sample, was characterised by severe and frequent problems in all pain dimensions, particularly in pain severity, night pain and limping, as well as in all dimensions of health-related quality of life. CONCLUSIONS: Patients with Oxford Knee Score pain subscale scores of 14 or less at six months after knee replacement can be considered to be in chronic pain that is likely to negatively affect their quality of life. This derived cut-off can be used for patient selection in research settings to design and assess interventions that support patients in their management of chronic post-surgical pain. PMID- 30285798 TI - An ABCG2 non-substrate anticancer agent FL118 targets drug-resistant cancer stem like cells and overcomes treatment resistance of human pancreatic cancer. AB - BACKGROUND: Pancreatic cancer is a deadly disease with a very low 5-year patient survival rate of 6-8%. The major challenges of eliminating pancreatic cancer are treatment resistance and stromal barriers to optimal drug access within the tumor. Therefore, effective molecular targeting drugs with high intra-tumor access and retention are urgently needed for managing this devastating disease in the clinic. METHODS: This study has used the following in vitro and in vivo techniques for the investigation of exceptional anticancer drug FL118's efficacy in treatment of resistant pancreatic cancer: cell culture; immunoblotting analysis to test protein expression; DNA sub-G1 flow cytometry analyses to test cell death; MTT assay to test cell viability; pancreatic cancer stem cell assays (fluorescence microscopy tracing; matrigel assay; CD44-positive cell colony formation assay); human luciferase-labeled pancreatic tumor orthotopic animal model in vivo imaging; pancreatic cancer patient-derived xenograft (PDX) animal models; and toxicology studies with immune-competent BALB/cj mice and beagle dogs. RESULTS: Our studies found that FL118 alone preferentially killed cisplatin resistant cancer cells, while a combination of FL118 with cisplatin synergistically killed resistant pancreatic cancer cells and reduced spheroid formation of treatment-resistant pancreatic cancer stem-like cells. Furthermore, using in vivo-imaging, we found that FL118 in combination with cisplatin strongly inhibited both drug-resistant pancreatic xenograft tumor growth and metastasis. In PDX model, we demonstrated that FL118 alone effectively eliminated PDX tumors, while FL118 in combination with gemcitabine eliminated PDX tumors that showed relative resistance (less sensitivity) to treatment with FL118. These FL118 efficacy results are consistent with our molecular-targeting data showing that FL118 inhibited the expression of multiple antiapoptotic proteins (survivin, Mcl 1, XIAP, cIAP2) and ERCC6, a critical regulator of DNA repair, in treatment resistant pancreatic stem-like cancer cells. Furthermore, FL118 toxicity studies in BALB/cj mice and beagle dogs indicated that FL118 exhibits favorable hematopoietic and biochemical toxicities. CONCLUSION: Together, our studies suggest that FL118 is a promising anticancer drug for further clinical development to effectively treat drug-resistant pancreatic cancer alone or in combination with other pancreatic cancer chemotherapeutic drugs. PMID- 30285800 TI - Satisfactory virological response and fibrosis improvement of sofosbuvir-based regimens for Chinese patients with hepatitis C virus genotype 3 infection: results of a real-world cohort study. AB - BACKGROUND: Chronic hepatitis C virus (HCV) genotype (GT) 3 infection with advanced liver disease has emerged as a challenging to treat by direct-acting antivirals (DAAs), but the efficacy of DAAs in Chinese HCV-GT3 patients is rarely reported. This study aimed to analyze the efficacy of sofosbuvir (SOF)-based regimens in Chinese patients with HCV-GT3 and compensated liver disease. METHODS: This was a registered retrospective study. All patients had completed at least 12 weeks SOF-based regimens therapy (with or without RBV), and were followed up for at least 24 weeks after therapy discontinuation. The primary endpoint was sustained virological response 24 weeks after end of therapy (SVR24). RESULTS: A total of 102 patients who completed at least 12 weeks therapy were finally included, with 57 in SOF + Daclatasvir (SOF + DCV), 24 in SOF + DCV + ribavirin (RBV) and 21 in SOF/Velpatasvir (SOF/VEL). The total SVR24 rate was achieved in 90.20% (92/102), with 85.96% (49/57) in SOF + DCV, 91.67% (22/24) in SOF + DCV + RBV and 100.00% (21/21) in SOF/VEL. Among 10 relapsed patients (8 in SOF + DCV and 2 in SOF + DCV + RBV), the short course (12 weeks) of therapy and no RBV addition may be the leading cause. In this cohort, the SVR24 rate was not statistically different between patients with and without cirrhosis (81.82% [27/33] vs. 94.20% [65/69], P = 0.073). Additionally, both FIB-4 (4.03 vs. 2.08, P < 0.001) and APRI (2.15 vs. 0.68, P < 0.001) scores were significant improved from baseline to week 24 after completion of therapy, regardless of the presence of cirrhosis. CONCLUSION: SOF-based regimens are highly effective in viral clearance and fibrosis remission for Chinese patients with HCV-GT3 infection. If available, SOF/VEL should be first considered. PMID- 30285801 TI - Plasticity changes in forebrain activity and functional connectivity during neuropathic pain development in rats with sciatic spared nerve injury. AB - Neuropathic pain is a major worldwide health problem. Although central sensitization has been reported in well-established neuropathic conditions, information on the acute brain activation patterns in response to peripheral nerve injury is lacking. This study first mapped the brain activity in rats immediately following spared nerve injury (SNI) of the sciatic nerve. Using blood oxygenation-level-dependent functional magnetic resonance imaging (BOLD-fMRI), we observed sustained activation in the bilateral insular cortices (ICs), primary somatosensory cortex (S1), and cingulate cortex. Second, this study sought to link this sustained activation pattern with brain sensitization. Using manganese enhanced magnetic resonance imaging (MEMRI), we observed enhanced activity in the ipsilateral anterior IC (AIC) in free-moving SNI rats on Days 1 and 8 post-SNI. Furthermore, enhanced functional connectivity between the ipsilateral AIC, bilateral rostral AIC, and S1 was observed on Day 8 post-SNI. Chronic electrophysiological recording experiments were conducted to confirm the tonic neuronal activation in selected brain regions. Our data provide evidence of tonic activation-dependent brain sensitization during neuropathic pain development and offer evidence that the plasticity changes in the IC and S1 may contribute to neuropathic pain development. PMID- 30285802 TI - Dietary supplement use among undergraduate male students in health and non-health cluster colleges of a public-sector university in Dammam, Saudi Arabia. AB - BACKGROUND: Dietary supplements (DS) are nutraceuticals that improve overall health and well-being of an individual as well as reduce the risk of diseases. Evidence indicates a rising prevalence of these products worldwide especially among college students. Studies have reported an increasing use of supplements among Saudi students. However, the scope of those researches was limited to prevalence data. Hence, the aim of our study was to document the prevalence, opinions, attitudes, reasons for use and monthly cost attributed to dietary supplement use. METHODS: A 3-month cross-sectional study was conducted to evaluate use of dietary supplement among health and non-health college students at a public-sector university in Dammam city, Saudi Arabia. It was conducted using Arabic version of the Dietary supplement questionnaire (DSQ-A). A total of 469 male students responded to the survey giving a response rate of 93.8%. The students were from ten colleges of the university. The data was analyzed by SPSS version 22. The study was approved by Institutional Review Board of Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia (IRB-UGS-2018-05-074). RESULTS: The overall prevalence of dietary supplement use in the university was 29.42%. In health cluster colleges, it was reported at 35.91% while in non-health cluster college it was 23.69%. Maintaining general health and well-being was the most common reason for use. Prevalence of multivitamins and whey proteins was approximately 23%. Average monthly cost of supplement was SAR 278.92 (USD 74.39). Cost was positively correlated (rho = 0.305) with satisfaction score. Students preferred brand products (16.4%). 41.4% students opined that DS may prevent chronic illness if used regularly and agreed that they are good for health. Majority of students (65%) recommended DS use only upon physician's recommendation. College clusters and study-year was associated (p-value< 0.01) with students' opinion. Students in health cluster colleges were more likely to recommend supplements (OR 3.715, p-value< 0.0001). CONCLUSION: Prevalence of dietary supplement use was lower than other local and international university students. Health cluster colleges had higher prevalence as compared to non-health cluster colleges. Multivitamins and whey protein were the most commonly used types of DS. Students preferred brand products, had positive opinions and attitudes towards dietary supplement. However, they recommended supplements use to others only upon a physician's recommendation. PMID- 30285804 TI - Pain neurophysiology knowledge among physical therapy students in Saudi Arabia: a cross-sectional study. AB - BACKGROUND: Pain is a leading cause of disability and accounts for many hospital and physical therapy visits. Current pain science understanding has evolved and changed substantially in the past 20 years; however, university health science curricula may not have progressed at the same rate. This study aimed to examine knowledge about pain neurophysiology among physical therapy students in Saudi Arabia, and to compare their knowledge across different education levels and by gender. METHODS: A cross-sectional study conducted to examine the pain neurophysiology knowledge among college physical therapy students in Saudi Arabia. The Revised Neurophysiology of Pain Questionnaire (12 items) was used. Descriptive statistics including frequencies and percentages were used to describe the sample. Analysis of variance and t-test were also used to examine the significant differences between scores. RESULTS: Physical therapy students (n = 202) from 18 different universities in Saudi Arabia participated in this study. The mean score of the participants on the questionnaire was 6.20 +/- 2.07 (i.e., 52% +/- 17%) and there was no significance difference between males and females. There was a statistically significant incremental increase in total score through the educational process (P < 0.05); however, this increase was very small comparing early- and final educational-level students (8% in RNPQ). CONCLUSION: While final year physical therapy students showed higher levels of pain science knowledge than those at the beginning of their course, the magnitude of the difference was small and likely of little meaningful relevance. This may reflect the need for more emphasis on pain science in the physical therapy curriculum in Saudi Arabia. PMID- 30285803 TI - Foxf2 plays a dual role during transforming growth factor beta-induced epithelial to mesenchymal transition by promoting apoptosis yet enabling cell junction dissolution and migration. AB - BACKGROUND: The most life-threatening step during malignant tumor progression is reached when cancer cells leave the primary tumor mass and seed metastasis in distant organs. To infiltrate the surrounding tissue and disseminate throughout the body, single motile tumor cells leave the tumor mass by breaking down cell cell contacts in a process called epithelial to mesenchymal transition (EMT). An EMT is a complex molecular and cellular program enabling epithelial cells to abandon their differentiated phenotype, including cell-cell adhesion and cell polarity, and to acquire mesenchymal features and invasive properties. METHODS: We employed gene expression profiling and functional experiments to study transcriptional control of transforming growth factor (TGF)beta-induced EMT in normal murine mammary gland epithelial (NMuMG) cells. RESULTS: We identified that expression of the transcription factor forkhead box protein F2 (Foxf2) is upregulated during the EMT process. Although it is not required to gain mesenchymal markers, Foxf2 is essential for the disruption of cell junctions and the downregulation of epithelial markers in NMuMG cells treated with TGFbeta. Foxf2 is critical for the downregulation of E-cadherin by promoting the expression of the transcriptional repressors of E-cadherin, Zeb1 and Zeb2, while repressing expression of the epithelial maintenance factor Id2 and miRNA 200 family members. Moreover, Foxf2 is required for TGFbeta-mediated apoptosis during EMT by the transcriptional activation of the proapoptotic BH3-only protein Noxa and by the negative regulation of epidermal growth factor receptor (EGFR) mediated survival signaling through direct repression of its ligands betacellulin and amphiregulin. The dual function of Foxf2 during EMT is underscored by the finding that high Foxf2 expression correlates with good prognosis in patients with early noninvasive stages of breast cancer, but with poor prognosis in advanced breast cancer. CONCLUSIONS: Our data identify the transcription factor Foxf2 as one of the important regulators of EMT, displaying a dual function in promoting tumor cell apoptosis as well as tumor cell migration. PMID- 30285805 TI - BHLHE40 confers a pro-survival and pro-metastatic phenotype to breast cancer cells by modulating HBEGF secretion. AB - BACKGROUND: Metastasis is responsible for a significant number of breast cancer related deaths. Hypoxia, a primary driving force of cancer metastasis, induces the expression of BHLHE40, a transcription regulator. This study aimed to elucidate the function of BHLHE40 in the metastatic process of breast cancer cells. METHODS: To define the role of BHLHE40 in breast cancer, BHLHE40 expression was knocked down by a lentiviral construct expressing a short hairpin RNA against BHLHE40 or knocked out by the CRISPR/Cas9 editing system. Orthotopic xenograft and experimental metastasis (tail vein injection) mouse models were used to analyze the role of BHLHE40 in lung metastasis of breast cancer. Global gene expression analysis and public database mining were performed to identify signaling pathways regulated by BHLHE40 in breast cancer. The action mechanism of BHLHE40 was examined by chromatin immunoprecipitation (ChIP), co immunoprecipitation (CoIP), exosome analysis, and cell-based assays for metastatic potential. RESULTS: BHLHE40 knockdown significantly reduced primary tumor growth and lung metastasis in orthotopic xenograft and experimental metastasis models of breast cancer. Gene expression analysis implicated a role of BHLHE40 in transcriptional activation of heparin-binding epidermal growth factor (HBEGF). ChIP and CoIP assays revealed that BHLHE40 induces HBEGF transcription by blocking DNA binding of histone deacetylases (HDAC)1 and HDAC2. Cell-based assays showed that HBEGF is secreted through exosomes and acts to promote cell survival and migration. Public databases provided evidence linking high expression of BHLHE40 and HBEGF to poor prognosis of triple-negative breast cancer. CONCLUSION: This study reveals a novel role of BHLHE40 in promoting tumor cell survival and migration by regulating HBEGF secretion. PMID- 30285806 TI - Image guidance and positioning accuracy in clinical practice: influence of positioning errors and imaging dose on the real dose distribution for head and neck cancer treatment. AB - BACKGROUND: Modern radiotherapy offers the possibility of highly accurate tumor treatment. To benefit from this precision at its best, regular positioning verification is necessary. By the use of image-guided radiotherapy and the application of safety margins the influence of positioning inaccuracies can be counteracted. In this study the effect of additional imaging dose by set-up verification is compared with the effect of dose smearing by positioning inaccuracies for a collective of head-and-neck cancer patients. METHODS: This study is based on treatment plans of 40 head-and-neck cancer patients. To evaluate the imaging dose several image guidance scenarios with different energies, techniques and frequencies were simulated and added to the original plan. The influence of the positioning inaccuracies was assessed by the use of real applied table shifts for positioning. The isocenters were shifted back appropriately to these values to simulate that no positioning correction had been performed. For the single fractions the shifted plans were summed considering three different scenarios: The summation of only shifted plans, the consideration of the original plan for the fractions with set-up verification, and the addition of the extra imaging dose to the latter. For both effects (additional imaging dose and dose smearing), plans were analyzed and compared considering target coverage, sparing of organs at risk (OAR) and normal tissue complication probability (NTCP). RESULTS: Daily verification of the patient positioning using 3D imaging with MV energies result in non-negligible high doses. kV imaging has only marginal influence on plan quality, primarily related to sparing of organs at risk, even with daily 3D imaging. For this collective, sparing of organs at risk and NTCP are worse due to potential positioning errors. CONCLUSION: Regular set-up verification is essential for precise radiation treatment. Relating to the additional dose, the use of kV modalities is uncritical for any frequency and technique. Dose smearing due to positioning errors for this collective mainly resulted in a decrease of OAR sparing. Target coverage also suffered from the positioning inaccuracies, especially for individual patients. Taking into account both examined effects the relevance of an extensive IGRT is clearly present, even at the expense of additional imaging dose and time expenditure. PMID- 30285807 TI - Adjacent segment degeneration or disease after cervical total disc replacement: a meta-analysis of randomized controlled trials. AB - BACKGROUND: Anterior cervical discectomy and fusion (ACDF) has been widely used in cervical spondylosis, but adjacent segment degeneration/disease (ASD) was inevitable. Cervical total disc replacement (TDR) could reduce the stress of adjacent segments and retard ASD in theory, but the superiority has not been determined yet. This analysis aimed that whether TDR was superior to ACDF for decreasing adjacent segment degeneration (ASDeg) and adjacent segment disease (ASDis). METHODS: A meta-analysis was performed according to the guidelines of the Cochrane Collaboration with PubMed, EMBASE, Cochrane Library and CBM (China Biological Medicine) databases. It included randomized controlled trials (RCTs) that reported ASDeg, ASDis, and reoperation on adjacent segments after TDR and ACDF. Two investigators independently selected trials, assessed methodological quality, and evaluated the quality of this meta-analysis using the grades of recommendation, assessment, development, and evaluation (GRADE) approach. RESULTS: Eleven studies with 2632 patients were included in the meta-analysis. The overall rate of ASD in TDR group was lower than ACDF group (OR = 0.6; 95% CI [0.38, 0.73]; P < 0.00001). Both the incidence of ASDeg and the reoperation rate were statistically lower in the TDR group than in the ACDF group (OR = 0.58, P < 0.00001; OR = 0.52, P = 0.01, respectively). Subgroup analysis was performed according to the follow-up time and trial site; the rate of ASDeg was lower in patients underwent TDR no matter the follow-up time, and TDR tended to increase the superiority across time. The rate of ASDeg was also lower with TDR both in the USA and China (P < 0.0001, P = 0.03, respectively). But the cost effectiveness result might be prone to neither of the two surgery approaches. According to GRADE, the overall quality of this meta-analysis was moderate. CONCLUSIONS: TDR decreased the rates of ASDeg and reoperation compared with that of ACDF, and the superiority may become more apparent over time. We cautiously and slightly suggest adopting TDR according to the GRADE but may not believe it excessively. PMID- 30285808 TI - Enhanced efficacy of histone deacetylase inhibitor combined with bromodomain inhibitor in glioblastoma. AB - BACKGROUND: Glioblastoma (GBM) is the most common and most malignant primary brain cancer in adults. Despite multimodality treatment, the prognosis is still poor. Therefore, further work is urgently required to discover novel therapeutic strategies for GBM treatment. METHODS: The synergistic effects of cotreatment with the histone deacetylase (HDAC) inhibitor panobinostat and bromodomain inhibitor JQ1 or OTX015 were validated using cell viability assays in GBM cell lines. Furthermore, the inhibitory mechanisms were investigated via an EdU proliferation assay, an apoptosis assay, qPCR, Western blot and RNAseq analyses. RESULTS: We found that the cotreatment with panobinostat and JQ1 or OTX015 synergistically inhibited cell viability in GBM cells. The cotreatment with panobinostat and JQ1 or OTX015 markedly inhibited cell proliferation and induced apoptosis in GBM cells. Compared with treatment with each drug alone, the cotreatment with panobinostat and JQ1 induced more profound caspase 3/7 activation and cytotoxicity. Mechanistic investigation showed that combination of panobinostat with JQ1 or OTX015 results in stronger repression of GBM-associated oncogenic genes or pathways as well as higher induction of GBM-associated tumor suppressive genes. CONCLUSION: Our study demonstrated that HDAC inhibitor and bromodomain inhibitor had synergistical efficacy against GBM cells. The cotreatment with HDAC inhibitor and bromodomain inhibitor warrants further attention in GBM therapy. PMID- 30285811 TI - Cost-effectiveness analysis of single use negative pressure wound therapy dressings (sNPWT) compared to standard of care in reducing surgical site complications (SSC) in patients undergoing coronary artery bypass grafting surgery. AB - BACKGROUND: There is a growing interest in using negative pressure wound therapy in closed surgical incision to prevent wound complications which continue to persist following surgery despite advances in infection measures. OBJECTIVES: To estimate the cost-effectiveness of single use negative pressure wound therapy (sNPWT) compared to standard of care in patients following coronary artery bypass grafting surgery (CABG) procedure to reduce surgical site complications (SSC) defined as dehiscence and sternotomy infections. METHOD: A decision analytic model was developed from the Germany Statutory Health Insurance payer's perspective over a 12-week time horizon. Baseline data on SSC, revision operations, length of stay, and readmissions were obtained from a prospective observational study of 2621 CABG patients in Germany. Effectiveness data for sNPWT was taken from a randomised open label trial conducted in Poland which randomised 80 patients to treatment with either sNPWT or standard care. Cost data (in Euros) were taken from the relevant diagnostic related groups and published literature. RESULTS: The clinical study reported an increase in wounds that healed without complications 37/40 (92.5%) in the sNPWT compared to 30/40 (75%) patients in the SC group p = 0.03. The model estimated sNPWT resulted in 0.989 complications avoided compared to 0.952 and the estimated quality adjusted life years were 0.8904 and 0.8593 per patient compared to standard care. The estimated mean cost per patient was ?19,986 for sNPWT compared to ?20,572 for SC resulting in cost-saving of ?586. The findings were robust to a range of sensitivity analyses. CONCLUSION: The sNPWT can be considered a cost saving intervention that reduces surgical site complications following CABG surgery compared to standard care. We however recommend that additional economic studies should be conducted as new evidence on the use of sNPWT in CABG patients becomes available to validate the results of this economic analysis. PMID- 30285809 TI - Membrane associated collagen XIII promotes cancer metastasis and enhances anoikis resistance. AB - BACKGROUND: Increased collagen expression and deposition are associated with cancer progression and poor prognosis in breast cancer patients. However, function and regulation of membrane-associated collagen in breast cancer have not been determined. Collagen XIII is a type II transmembrane protein within the collagen superfamily. Experiments in tissue culture and knockout mouse models show that collagen XIII is involved in cell adhesion and differentiation of certain cell types. In the present study, we determined roles of collagen XIII in breast cancer progression and metastasis. METHODS: We analyzed the association of collagen XIII expression with breast cancer development and metastasis using published gene expression profiles generated from human breast cancer tissues. Utilizing gain- and loss- of function approaches and 3D culture assays, we investigated roles of collagen XIII in regulating invasive tumor growth. Using the tumorsphere/mammosphere formation assay and the detachment cell culture assay, we determined whether collagen XIII enhances cancer cell stemness and induces anoikis resistance. We also inhibited collagen XIII signaling with beta1 integrin function-blocking antibody. Finally, using the lung colonization assay and the orthotopic mammary tumor model, we investigated roles of collagen XIII in regulating breast cancer colonization and metastasis. Cox proportional hazard (log-rank) test, two-sided Student's t-test (two groups) and one-way ANOVA (three or more groups) analyses were used in this study. RESULTS: Collagen XIII expression is significantly higher in human breast cancer tissue compared with normal mammary gland. Increased collagen XIII mRNA levels in breast cancer tissue correlated with short distant recurrence free survival. We showed that collagen XIII expression promoted invasive tumor growth in 3D culture, enhanced cancer cell stemness, and induced anoikis resistance. Collagen XIII expression induced beta1 integrin activation. Blocking beta1 integrin activation significantly reduced collagen XIII-induced invasion and mammosphere formation. Importantly, silencing collagen XIII in MDA-MB-231 cells reduced lung colonization and metastasis. CONCLUSIONS: Our results demonstrate a novel function of collagen XIII in promoting cancer metastasis, cell invasion, and anoikis resistance. PMID- 30285810 TI - Lymphatic endothelial cells promote productive and latent HIV infection in resting CD4+ T cells. AB - BACKGROUND: An HIV cure has not yet been achieved because latent viral reservoirs persist, particularly in resting CD4+ T lymphocytes. In vitro, it is difficult to infect resting CD4+ T cells with HIV-1, but infections readily occur in vivo. Endothelial cells (EC) line the lymphatic vessels in the lymphoid tissues and regularly interact with resting CD4+ T cells in vivo. Others and we have shown that EC promoted productive and latent HIV infection of resting CD4+ T cells. However, the EC used in previous studies were from human umbilical cords (HUVEC), which are macrovascular; whereas EC residing in the lymphoid tissues are microvascular. METHODS: In this study, we investigated the effects of microvascular EC stimulation of resting CD4+ T cells in establishing viral infection and latency. Human resting and activated CD4+ T cells were cultured alone or with endothelial cells and infected with a pseudotyped virus. Infection levels, indicated by green fluorescent protein expression, were measured with flow cytometry and data was analyzed using Flowing Software and Excel. RESULTS: We confirmed that EC from lymphatic tissue (LEC) were able to promote HIV infection and latency formation in resting CD4+ T cells while keeping them in resting phenotype, and that IL-6 was involved in LEC stimulation of CD4+ T cells. However, there are some differences between stimulation by LEC and HUVEC. Unlike HUVEC stimulation, we demonstrated that LEC stimulation of resting memory T cells does not depend on major histocompatibility complex class II (MHC II) interactions with T cell receptors (TCR) and that CD2-CD58 interactions were not involved in LEC stimulation of resting T cells. LEC also secreted lower levels of IL-6 than HUVEC. We also found that LEC stimulation increases HIV infection rates in activated CD4+ T cells. CONCLUSIONS: While differences in T cell stimulation between lymphatic EC and HUVEC were observed, we confirmed that similar to macrovascular EC stimulation, microvascular EC stimulation promotes direct HIV infection and latency formation in resting CD4+ T cells without T cell activation. LEC stimulation also increased infection rates in activated CD4+ T cells. Additionally, the present study established a physiologically more relevant model of EC interactions with resting CD4+ T cells and further highlighted the importance of investigating the roles of EC in HIV infection and latency in both resting and activated CD4+ T cells. PMID- 30285813 TI - Long-term clinical outcomes in patients with viral hepatitis related liver cirrhosis after transjugular intrahepatic portosystemic shunt treatment. AB - BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) procedure has played a vital role in management of portal hypertension. Thus, we aimed to investigate the natural history, long-term clinical outcome, predictors of survival in viral hepatitis related cirrhotic patients post-TIPS. METHOD: A total of 704 patients with complete followed-up data were enrolled, and clinical characteristics of patients were collected and analyzed. Kaplan-Meier method was used to calculate survival, and comparisons were made by log rank test. A multivariate analysis of factors influencing survival was carried out using the Cox proportional hazards regression model. RESULTS: TIPS implatantion significantly decreased portal vein pressure with 9.77 cmH2O reduction, without influencing long-term liver functions. The total incidence rate of major complication post-TIPS, including HE and re-bleeding/bleeding, was 37.9% and 15.5%, respectively. Patients in Child-Pugh C stage revealed higher overt hepatic encephalopathy (HE) occurrence (65.6%), while patients receiving covered, 6 mm in diameter stents indicated notably lower incidence of HE in comparison with other groups (6.4%). The median survival was > 60 months, 27.0 months, and 11.5 months in cirrhotic patients with variceal bleeding, refractory ascites, and both complications, respectively. The cumulative 5-year survival was significantly higher in patients with variceal bleeding (75.6%) in comparison with either that in patients with refractory ascites (12.5%) or that in patients with both complications (1.96%) (P < 0.0001). Covered stents usage, baseline model for end stage liver disease (MELD) score, and baseline Child-Pugh classification were predictive of survival (P < 0.001). Other variables including age, male gender, and pre-TIPS PVP were not emerged as significant predictors (P > 0.05). CONCLUSION: TIPS was an effective and safe therapeutic method for decompression of portal hypertension and for treatment of its complications. Careful selection of patients with minimal liver dysfunction for TIPS implantation was essential for better long-term outcomes. PMID- 30285812 TI - A novel model to correlate hydrogel spacer placement, perirectal space creation, and rectum dosimetry in prostate stereotactic body radiotherapy. AB - BACKGROUND: The SpaceOAR hydrogel is employed to limit rectal radiation dose during prostate radiotherapy. We identified a novel parameter - the product of angle theta and hydrogel volume - to quantify hydrogel placement. This parameter predicted rectum dosimetry and acute rectal toxicity in prostate cancer patients treated with stereotactic body radiotherapy to 36.25 Gy in 5 fractions. METHODS: Twenty men with low- and intermediate-risk prostate cancer underwent hydrogel placement from 2015 to 2017. Hydrogel symmetry was assessed on the CT simulation scan in 3 axial slices (midgland, 1 cm above midgland, 1 cm below midgland). Two novel parameters quantifying hydrogel placement - hydrogel volume and angle theta formed by the prostate, hydrogel, and rectum - were measured, and the normalized product of theta and hydrogel volume calculated. These were then correlated with perirectal distance, rectum maximum 1-3 cc point doses (rDmax 1-3 cc), and rectum volumes receiving 80-95% of the prescription dose (rV80-95%). Acute rectal toxicity was recorded per RTOG criteria. RESULTS: In 50% of patients, hydrogel placement was symmetric bilaterally to within 1 cm of midline in all three CT simulation scan axial slices. Lateral hydrogel asymmetry < 2 cm in any one axial slice did not affect rectum dosimetry, but absence of hydrogel in the inferior axial slice resulted in a mean increase of 171 cGy in the rDmax 1 cc (p < 0.005). The perirectal distance measured at prostate midgland, midline (mean 9.1 +/- 4.3 mm) correlated strongly with rV95 (R2 0.6, p < 0.001). The mean hydrogel volume and theta were 10.3 +/- 4.5 cc and 70 +/- 49 degrees , respectively. Perirectal distance, rV95 and rDmax 1 cc correlated with hydrogel angle theta (p < 0.01), and yet more strongly with the novel metric theta*hydrogel volume (p < 0.001). With a median follow up of 14 months, no rectal toxicity >grade 2 was observed. Low grade rectal toxicity was observed in a third of men and resolved within 1 month of SBRT. Men who had these symptoms had higher rDmax 1 cc and smaller theta*hydrogel volume measurements. CONCLUSIONS: Optimal hydrogel placement occurs at prostate midgland, midline. The novel parameter theta*hydrogel volume describes a large proportion of rectum dosimetric benefit derived from hydrogel placement, and can be used to assess the learning curve phenomenon for hydrogel placement. PMID- 30285815 TI - Impact of graft and tunnel orientation on patient-reported outcome in anterior cruciate ligament reconstruction using bone-patellar tendon-bone autografts. AB - BACKGROUND: The optimal positioning of anterior cruciate ligament graft is still controversially discussed. We therefore wanted to determine the tunnel-to-joint (TJA), tunnel-to-shaft (TSA), and graft-tunnel divergence angles which would provide the best outcome, determined by the KOOS (Knee Injury and Osteoarthritis Outcome Score). This study evaluated the clinical influence of graft orientation as measured with the KOOS questionnaire in patients with anterior cruciate ligament reconstruction with bone-patellar tendon-bone autografts. METHODS: We designed a prospective cohort study, with a 1 1/4 year recruitment phase from March 2011 to July 2012 and a minimal follow-up period of 1 year. Inclusion criteria were patients >= 18 years of age receiving an ACL reconstruction with bone-patellar tendon-bone autografts at our institution after having suffered an acute ACL rupture. The primary outcome was the KOOS. Independent variables were patient age, gender, laterality of rupture, mechanism of trauma, and type of femoral and tibial fixation, as well as sagittal graft-tunnel divergence, TJA, and TSA, the latter two being assessed on coronal slices of magnetic resonance imaging. Equations modeling the relationship between TJA, TSA, and graft-tunnel divergence with the KOOS overall score were fitted, and the optimum angles were mathematically determined. RESULTS: In total, 31 patients were included in our study. Our cohort with a median age of 28 years was predominantly male. The mathematically determined optimal placement of the implant in the coronal plane was a TJA of 74.8 degrees , a TSA of 80.1 degrees , and a graft-tunnel divergence angle of 8.5 degrees . CONCLUSION: With regard to patient-reported outcome, the optimal graft orientation is provided by a coronal tunnel-to-shaft angle of 80 degrees and tunnel-to-joint angle of 75 degrees , respectively. Interestingly, in our series, patients reported best clinical outcomes with a sagittal graft tunnel divergence. These results should be validated in larger studies. PMID- 30285814 TI - Can a brief psychological intervention improve oral health behaviour? A randomised controlled trial. AB - BACKGROUND: Dental caries is a major public health issue affecting a large proportion of the general population. The disease is associated with behavioural factors and is thus preventable to a high degree. Individuals may need assistance to be able to change their oral health behaviour. There is a lack of such interventions for adults affected by severe caries. The aim of the study was to evaluate the effect of Acceptance and Commitment Therapy (ACT), a form of cognitive behavioural therapy, on oral health behaviour in young adults with poor oral health. METHODS: The study included a two group parallel randomised controlled trial at general dental clinics, with young adults, 18-25 years of age, >= two manifest proximal dental caries lesions (n = 135); 67 were treated with ACT and 68 with standard disease information only, respectively. Primary outcomes: oral health behaviours (tooth-brushing, flossing, use of toothpicks, and additional fluoride use). The CONSORT principles for RCTs were used, including intention-to-treat and per protocol analyses. The Chi-square, Mann Whitney, and Wilcoxon Signed Rank tests were applied, including effect sizes. RESULTS: The study groups did not differ with regard to oral health behaviour variables at baseline. The intervention group improved all their oral health behaviours significantly over time (effect sizes, 0.26-0.32), while the control group showed improved behaviours on two measures (flossing and additional use of fluoride, effect sizes, 0.22-0.23). CONCLUSIONS: By testing a psychological intervention on young adults (18-25 years of age) with a high prevalence of caries, we found an immediate positive effect with improved oral health behaviours.

PMID- 30285816 TI - Urea cycle disorders in India: clinical course, biochemical and genetic investigations, and prenatal testing. AB - BACKGROUND: Urea cycle disorders (UCDs) are inherited metabolic disorders that present with hyperammonemia, and cause significant mortality and morbidity in infants and children. These disorders are not well reported in the Indian population, due to lack of a thorough study of the clinical and molecular profile. RESULTS: We present data from two major metabolic centres in India, including 123 cases of various UCDs. The majority of them (72/123, 58%) presented in the neonatal period (before 30 days of age) with 88% on or before day 7 of life (classical presentation), and had a high mortality (64/72, 88%). Citrullinemia type 1 was the most common UCD, observed in 61/123 patients. Ornithine transcarbamylase (OTC) deficiency was the next most common, seen in 24 cases. Argininosuccinic aciduria was diagnosed in 20 cases. Deficiencies of arginase, N-acetylglutamate synthase, carbamoyl phosphate synthetase, citrin, and lysinuric protein intolerance were also observed. Molecular genetic analysis revealed two common ASS1 mutations: c.470G > A (p.Arg157His) and c.1168G > A (p.Gly390Arg) (36 of 55 tested patients). In addition, few recurrent point mutations in ASL gene, and a deletion of the whole OTC gene were also noted. A total of 24 novel mutations were observed in the various genes studied. We observed a poor clinical outcome with an overall all time mortality of 63% (70/110 cases with a known follow-up), and disability in 70% (28/40) among the survivors. Prenatal diagnosis was performed in 30 pregnancies in 25 families, including one pre-implantation genetic diagnosis. CONCLUSIONS: We report the occurrence of UCDs in India and the spectrum that may be different from the rest of the world. Citrullinemia type 1 was the most common UCD observed in the cohort. Increasing awareness amongst clinicians will improve outcomes through early diagnosis and timely treatment. Genetic diagnosis in the proband will enable prenatal/pre-implantation diagnosis in subsequent pregnancies. PMID- 30285817 TI - Assessment of the effect of the corticotomy-assisted orthodontic treatment on the maxillary periodontal tissue in patients with malocclusions with transverse maxillary deficiency: a case series. AB - BACKGROUND: The aim of the study was to assess the effect of corticotomy-assisted orthodontic treatment on soft tissue clinical parameters in patients with malocclusions with transverse maxillary deficiency. METHODS: The study included 20 generally healthy adult individuals with malocclusion, who underwent a corticotomy-assisted orthodontic treatment in maxilla. During the corticotomy performed after full-thickness flap elevation, only the buccal cortical plate was cut with the use of OTS-7, OTS7-4, OTS7-3 ultrasound tips of the piezosurgery device (Mectron s. p. a., Italy). A clinical examination was performed prior to the corticotomy procedure, then repeated - 3, 6, 9 and 12 months after the procedure. The following parameters were assessed: FMPI (full mouth plaque index), FMBOP (full mouth bleading on probing), PD (probing depth), CAL (clinical attachment level), GR (gingival recession height), RW (recession width), PH (papilla height), PW (papilla width), BS (bone sounding), biotype and KT. RESULTS: There was a statistically significant reduction in PD (mean difference: 0.06; 95% Cl: - 0.33, - 0.18), CAL (mean difference: 0.07; 95% Cl: - 0.33, - 0.19), PH (mean difference: 0.26; 95% Cl: - 0.47, 0.05) and BS (mean difference: 0.13; 95% Cl: - 0.41, - 0.14) after the treatment. Statistically significant changes were also noted in relation to KT (mean difference: 0.17; 95% Cl: - 0.07, 0.27) and biotype (mean difference: 0.07; 95% Cl: 0.26, 0.39), which thickness increased significantly after the treatment. No statistically significant differences were observed in GR, RW and PW. CONCLUSIONS: The corticotomy-assisted orthodontic treatment did not jeopardize the periodontal clinical status in maxilla. There is a need for further studies on a larger number of patient to compare the clinical findings with a control group as well as in patients with conventional orthodontic treatment in a longer follow-up time to find out more about the post-treatment periodontal tissue changes and stability.

PMID- 30285818 TI - Physician experience with speech recognition software in psychiatry: usage and perspective. AB - OBJECTIVE: The purpose of this paper is to extend a previous study by evaluating the use of a speech recognition software in a clinical psychiatry milieu. Physicians (n = 55) at a psychiatric hospital participated in a limited implementation and were provided with training, licenses, and relevant devices. Post-implementation usage data was collected via the software. Additionally, a post-implementation survey was distributed 5 months after the technology was introduced. RESULTS: In the first month, 45 out of 51 (88%) physicians were active users of the technology; however, after the full evaluation period only 53% were still active. The average active user minutes and the average active user lines dictated per month remained consistent throughout the evaluation. The use of speech recognition software within a psychiatric setting is of value to some physicians. Our results indicate a post-implementation reduction in adoption, with stable usage for physicians who remained active users. Future studies to identify characteristics of users and/or technology that contribute to ongoing use would be of value. PMID- 30285820 TI - Factors associated with high-risk human papillomavirus test utilization and infection: a population-based study of uninsured and underinsured women. AB - BACKGROUND: Current cervical cancer screening guidelines recommend a Pap test every 3 years for women age 21-65 years, or for women 30-65 years who want to lengthen the screening interval, a combination of Pap test and high-risk human papilloma virus testing (co-testing) every 5 years. Little population-based data are available on human papilloma virus test utilization and human papilloma virus infection rates. The objective of this study was to examine the patient-level, cervical cancer screening, and area-level factors associated with human papilloma virus testing and infection among a diverse sample of uninsured and underinsured women enrolled in the New Jersey Cancer Early Education and Detection (NJCEED) Program. METHODS: We used data for a sample of 50,510 uninsured/underinsured women, age >= 29 years, who screened for cervical cancer through NJCEED between January 1, 2009 and December 31, 2015. Multivariable logistic regression models were used to estimate associations between ever having a human papilloma virus test or a positive test result, and individual- (age, race/ethnicity, birthplace) and area-level covariates (% below federal poverty level, % minority, % uninsured), and number of screening visits. RESULTS: Only 26.6% (13,440) of the sample had at least one human papilloma virus test. Among women who underwent testing, 13.3% (1792) tested positive for human papilloma virus. Most women who were positive for human papilloma virus (99.4%) had their first test as a co test. Human papilloma virus test utilization and infection were significantly associated with age, race/ethnicity, birthplace (country), and residential area level poverty. Rates of human papilloma virus testing and infection also differed significantly across counties in the state of New Jersey. CONCLUSIONS: These findings suggest that despite access to no-cost cervical cancer screening for eligible women, human papilloma virus test utilization was relatively low among diverse, uninsured and underinsured women in New Jersey, and test utilization and infection were associated with individual-level and area-level factors. PMID- 30285821 TI - Significant reductions in tertiary hospital encounters and less travel for families after implementation of Paediatric Care Coordination in Australia. AB - BACKGROUND: Over a third of Australian children have long-term health conditions, often involving multiple organ systems and resulting in complex health care needs. Our healthcare system struggles to meet their needs because of sectoral fragmentation and episodic models of care. Children with medical complexity (CMC) currently rely on tertiary paediatric hospitals for most of their healthcare, but this is not sustainable. We evaluated the impacts of Care Coordination on tertiary hospital service use and family outcomes. METHODS: A pre- and post implementation cohort evaluation of the Care Coordination service at a tertiary paediatric hospital network, was undertaken. From July 2015 CMC enrolled in the service had access to a Care Coordinator, shared-care plans, linkage with local general practitioners (GPs), and access to a 24-h Hotline from August 2016. CMC were those with >=4 emergency department (ED) presentations, hospital stays of >=14 days, or >= 10 outpatient appointments in 12 months. Medically fragile infants at risk of frequent future hospital utilisation, and children with medical problems complicated by difficult family psychosocial circumstances were also included. Care Coordinators collected outcomes for each enrolled child. Administrative data on hospital encounters 6 months pre- and post-enrolment were analysed for children aged > 6 months. RESULTS: An estimated 557 hospital encounters, were prevented in the 6 months after enrolment, for 534 children aged > 6 months. ED presentations decreased by 40% (Chi2 = 37.95; P < 0.0001) and day only admissions by 42% (Chi2 = 7.54; P < 0.01). Overnight admissions decreased by 9% but this was not significant. An estimated Au$4.9 million was saved over 2 years due to prevented hospital encounters. Shared-care plans were developed for 83.5%. Of 84 children who had no regular GP, 58 (69%) were linked with one. Fifty five (10%) of families were linked to the 24-h Hotline to enable remote access to support and advice. Over 50,000 km of family travel and 370 school absences was prevented. CONCLUSIONS: The Care Coordination service has clear benefits for the tertiary paediatric hospital network and for families. Ongoing evaluation is essential for continuous improvement and to support adjustments to the model according to the local context.

AB - OBJECTIVE: To understand factors associated with community-associated methicillin resistant Staphylococcus aureus (CA-MRSA) acquisition and infection, we mapped public places (including personal service establishments, fitness centers, pools, schools, and daycares) visited by members of households affected by CA-MRSA skin and soft tissue infection. RESULTS: From January 2012 to October 2015, households of children with CA-MRSA SSTI in metropolitan St. Louis were enrolled in the HOME: Household Observation of MRSA in the Environment study. Addresses of public places visited within 3 months of enrollment were reported by 671 participants and were analyzed using a geographic information system (GIS). The Nearest Neighbor Tool in ArcGIS assessed clustering of public places within the study region. Public places were significantly clustered within the study area compared to the expected distance between locations (p < 0.001). Additionally, one-third (48/150) of participating households visited at least one public place in common with other households. No significant relationship between participants visiting the public places within 3 months of enrollment and subsequent colonization or SSTI were found. Understanding community behavior is critical to informing public health initiatives to reduce the prevalence of CA-MRSA infections. PMID- 30285822 TI - Association between brain-derived neurotrophic factor gene polymorphisms and fibromyalgia in a Korean population: a multicenter study. AB - BACKGROUND: Several lines of evidence imply that brain-derived neurotrophic factor (BDNF) is involved in the pathophysiology of fibromyalgia (FM); in this regard, patients with FM have altered blood and cerebrospinal fluid levels of BDNF. In this study, we explored the association between BDNF gene polymorphisms and FM susceptibility and the severity of symptoms. METHODS: In total, 409 patients with FM and 423 healthy controls in 10 medical centers were enrolled from the Korean nationwide FM survey. The alleles and genotypes at 10 positions in the BDNF gene were genotyped. RESULTS: The allele and genotype frequencies of BDNF rs11030104 differed significantly between the patients with FM and the controls (P = 0.031). The GG genotype of rs11030104 had a protective effect against FM (P = 0.016), and the G allele of rs11030104 was negatively associated with the presence of FM compared with the A allele (P = 0.013). In comparison, although the allele and genotype frequencies of BDNF rs12273539 did not differ between the two groups, the TT genotype of BDNF rs12273539 was associated with susceptibility to FM (P = 0.038). Haplotype analyses implied that some BDNF haplotypes have a protective effect against FM. Finally, several genotypes and haplotypes of the BDNF gene contributed to specific symptoms of FM. CONCLUSIONS: This study is the first to evaluate the associations between BDNF gene polymorphisms and FM. Our results imply that some BDNF single-nucleotide polymorphisms and haplotypes are associated with susceptibility to, and contribute to the symptoms of, FM. PMID- 30285823 TI - A web-based education program to encourage organ donation registration among lower-educated adolescents in the Netherlands: study protocol for a cluster randomized controlled trial. AB - BACKGROUND: The gap between the supply and demand of organ donors is substantial, causing patients to suffer from long waiting times. Moreover, the lack of registrations places a burden on family members and medical professionals when an unregistered individual dies. This article describes a cluster randomized controlled trial (CRCT) study to assess the effectiveness and quality of implementation of a web-based program aimed at encouraging lower-educated adolescents to register a well-informed choice about organ donation, regardless of it being as a donor or not. METHODS/DESIGN: The program will be delivered by teachers at schools for Intermediate Vocational Education in the Netherlands. The effectiveness will be assessed in a CRCT design with post-test only using self administered questionnaires for the primary outcome (i.e. intention to register). Classes will be matched to improve equivalence of groups. From each pair of matched classes, one class will be randomly assigned to the experimental condition, and the other assigned to the control condition. Students in the control groups will fill in the questionnaire before receiving the program, while the experimental groups will do this afterwards. A post-test design prevents the risk of testing bias. The required sample size is 14 schools, with 10 classes per school and 13 unregistered students per class. The questionnaire assesses demographics, behavioural determinants (attitude, self-efficacy, knowledge and social outcomes), intention to register (as a donor) and registration status. Six months after delivery, registration status will be assessed again. Additionally, a process evaluation will be conducted to evaluate the quality of implementation using both qualitative (i.e. semi-structured interviews) and quantitative (i.e. logbooks, questionnaires, Google Analytics to track user behaviour at the website) methods. DISCUSSION: Findings of the study can help to further improve the program and serve as a basis for a solid dissemination plan. Moreover, the study will provide insight into (change in) determinants of registration and donorship and the translation of research into practice of school-based health promotion interventions, which can serve as an example for others.

PMID- 30285825 TI - The feasibility of following up prisoners, with mental health problems, after release: a pilot trial employing an innovative system, for engagement and retention in research, with a harder-to-engage population. AB - BACKGROUND: Following up released prisoners is demanding, particularly for those prisoners with mental health problems, for whom stigma and chaotic lifestyles are problematic. Measurement of mental health outcomes after release is challenging. To evaluate mental healthcare for offender populations, using high-quality randomised controlled trials, evidenced-based methods must be developed to engage them while in custody, to locate and re-interview them after release, and to collect potentially stigmatising mental health outcomes data. METHODS: We developed an initial theoretical model and operational procedures for collecting baseline and follow-up data informed by a literature search, focus groups, and case studies. Male prisoners from five prisons in two sites were invited to participate. The inclusion criteria included individuals who were above threshold on nine-item Patient Health Questionnaire, seven-item Generalized Anxiety Disorder, or post-traumatic stress disorder scales, or who had reported mental health problems in the past 2 years or had been assessed with a likely personality disorder. Potential participants were interviewed to generate baseline data and were re-contacted before their release. We then contacted them for a follow-up interview, which included repeating the earlier data collection measures 2-8 weeks after release. A qualitative formative process evaluation produced and refined a model procedure for the recruitment and retention of male prison leavers in trials, identified the mechanisms which promoted engagement and retention, and mapped these against a theoretical behaviour change model. RESULTS: We developed a flexible procedure which was successful in recruiting male prison leavers to a pilot trial: 185/243 (76%, 95% confidence interval (CI) 70-81%) of those approached agreed to participate. We also retained 63% (95% CI 54-71%) of those eligible to participate in a follow-up interview 2-8 weeks after release. Mental health outcomes data was collected at both these time points. CONCLUSIONS: It is possible to design acceptable procedures to achieve sustained engagement critical for delivering and evaluating interventions in prison and in the community and to collect mental health outcomes data. These procedures may reduce attrition bias in future randomised controlled trials of mental health interventions for prison leavers. This procedure has been replicated and successfully delivered in a subsequent pilot trial and a definitive randomised controlled trial. PMID- 30285826 TI - The clinician-scientist track: an approach addressing Australia's need for a pathway to train its future clinical academic workforce. AB - BACKGROUND: Clinician-scientist training represents the epitome of preparation for biomedical scientific discovery. The significance of, and need for, clinician scientists is universally recognised as essential to progress medical research across what is regarded as the 'translational gap'. Despite a rich history of cutting-edge biomedical research, Australia has no infrastructure or career pathway for training clinician-scientists. DISCUSSION: The Clinician-scientist Track (CST) was developed to address this concern at the University of Queensland. The CST concept began in 2010 with the Concurrent MD-Masters that allowed students to undertake a research Masters concurrently with their medical program. The rationale was to offer an attractive and realistic option to recruit our highest performing students into a research higher degree, with the underlying aim of encouraging those most capable, to transfer to the MD-PhD. The Concurrent MD-Masters was immediately popular and remains so. Over 8 years, enrolments rose seven-fold (60 MD-Masters, 36 MD-PhDs). The transfer rate from MD Masters to MD-PhD is 28% supporting our original aim. CONCLUSIONS: Many challenges remain for the future of the program. These challenges are underpinned by a culture that values clinician-scientists as crucial to ensuring that high quality health and medical research is undertaken and translated to patient care, but lags behind in establishing an infrastructure to develop and maintain a new generation of this vital workforce. A future challenge is to develop a coordinated approach to a supported Australian MD-PhD pathway for our most talented and committed students beginning in the undergraduate Bachelor's degree into the medical degree and throughout specialty training. Shared responsibility is necessary between institutions and stakeholders to support and nurture newly trained MD-PhDs into the post-graduate years. Flexibility across this medical training continuum that allows integration of both degrees will help ensure students make the most meaningful connections between the research and the medicine. What is paramount will be acknowledging the career expectations of an emerging cohort of medical students, in particular females, wishing to pursue research. Without these considerations we risk losing our next generation of potential clinician-scientists. PMID- 30285827 TI - Dietary factors associated with preeclampsia or eclampsia among women in delivery care services in Addis Ababa, Ethiopia: a case control study. AB - OBJECTIVE: Preeclampsia or eclampsia, which is one of the direct obstetric complication, results in maternal and child morbidity and mortality. The factors associated with it remains unclear. So, the aim of the study was to assess the dietary factors associated with preeclampsia or eclampsia among women in delivery care services in Addis Ababa, Ethiopia. RESULTS: Factors which were investigated as protective for preeclampsia or eclampsia were: Fruit intake during pregnancy (AOR: 0.94, 95% CI 0.20, 4.32), vegetable intake during pregnancy (AOR: 0.95, 95% CI 0.01, 0.71) and receiving nutritional counseling during antenatal care (AOR: 0.17, 95% CI 0.05, 0.6). In the other side being nulliparous women was a risk factor for preeclampsia or eclampsia (AOR: 2.02, 95% CI 1.15, 3.55). PMID- 30285828 TI - Influence of HLA-B27 on the Ankylosing Spondylitis phenotype: results from the REGISPONSER database. AB - OBJECTIVE: To assess HLA-B27 influence on the clinical phenotype of Ankylosing Spondylitis (AS) patients. METHOD: An observational, cross-sectional and descriptive study of AS patients from the Spanish REGISPONSER database was performed. Demographic, clinical, disease activity (Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP)), and radiographic data (Bath Ankylosing Spondylitis Radiology Index (BASRI) score) were compared regarding HLA-B27 status. A univariate and multivariate analysis was performed to identify variables independently related to the presence of HLA B27. RESULTS: Data from 1235 patients (74.8% male) were analyzed; 1029 were HLA B27 positive (83%). HLA-B27-positive patients showed higher family aggregation and an earlier onset of disease compared with those who were HLA-B27 negative. HLA-B27-negative patients presented statistically higher BASDAI and BASFI scores and higher prevalence of arthritis, dactylitis, and extra-articular manifestations (psoriasis and inflammatory bowel disease (IBD)) but not anytime uveitis compared with those who were HLA-B27 positive. In the multivariate analysis, family history (odds ratio (OR) 2.10, 95% confidence interval (CI) 1.27 3.49), younger age at diagnosis (OR 0.97, 95% CI 0.96-0.98), presence of peripheral arthritis (OR 0.53, 95% CI 0.32-0.89), dactylitis (OR 0.16, 95% CI 0.05-0.56), psoriasis (OR 0.45, 95% CI 0.26-0.78), and IBD (OR 0.22, 95% CI 0.12 0.40) were the main variables independently related to the presence or not of HLA B27. CONCLUSION: In Caucasian AS patients, the presence of HLA-B27 is related to an earlier disease onset and higher family aggregation. Absence of HLA-B27 is related to a higher frequency of peripheral arthritis, dactylitis, and extra articular manifestations. Being HLAB27 positive is not related to a higher burden of disease or anytime uveitis. PMID- 30285830 TI - Late presentation, MR imaging features and surgical treatment of Herlyn-Werner Wunderlich syndrome (classification 2.2); a case report. AB - BACKGROUND: Herlyn-Werner-Wunderlich syndrome is a very rare congenital genitourinary anomaly characterized by uterus didelphys, blind hemivagina and ipsilateral renal agenesis. CASE PRESENTATION: Authors present a case of Herlyn Werner-Wunderlich syndrome in a 19-year-old unmarried woman who presented with pelvic pain and pelvic mass. MR imaging revealed the typical features of didelphys uterus, obstructed right hemivagina and ipsilateral renal agenesis. The patient subsequently underwent surgery. CONCLUSIONS: Herlyn-Werner-Wunderlich syndrome would be suspected in patients with unilateral absent kidney and pelvic mass. Ultrasonography and MR imaging can well depict the disease entity and surgery is the treatment of choice for obstructed hemivagina. PMID- 30285829 TI - CYLD suppression enhances the pro-inflammatory effects and hyperproliferation of rheumatoid arthritis fibroblast-like synoviocytes by enhancing NF-kappaB activation. AB - BACKGROUND: Rheumatoid arthritis fibroblast-like synoviocytes (RA-FLSs) actively drive joint inflammation and degradation by producing inflammatory cytokines and matrix-degrading molecules, making them key factors in the pathogenesis of RA. Cylindromatosis (CYLD) is a tumor suppressor that downregulates nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappaB) activation by deubiquitinating NF-kappaB essential modulator and tumor necrosis factor receptor associated factors 2 and 6. In this study, we aimed to determine CYLD expression in the synovium of patients with RA, analyze its correlation with NF-kappaB activation and clinical disease activity, further investigate CYLD expression in RA-FLSs, and explore CYLD's roles and mechanisms in the pro-inflammatory effects, proliferation, apoptosis, and cell cycles of RA-FLSs. METHODS: We obtained synovia from 50 patients with active RA and 20 with osteoarthritis (OA) and then cultured FLSs from the samples. We determined CYLD expression in the synovia of RA patients and in FLSs via reverse transcription polymerase chain reaction (RT PCR). CYLD was depleted by lentiviral CYLD short hairpin ribonucleic acid. We used RT-PCR and enzyme-linked immunosorbent assay to analyze the expression of pro-inflammatory cytokines, matrix metalloproteinases (MMPs), and receptor activator of nuclear factor kappa-B ligand (RANKL). We detected cell proliferation using Cell Counting Kit-8 and examined cell apoptosis and cell cycle using flow cytometry. RESULTS: We obtained the following results: 1. In synovia from patients with RA, CYLD expression was significantly downregulated while NF-kappaB expression was distinctly upregulated, compared with synovia from patients with OA. Thus, there is a significant inverse correlation between CYLD and NF-kappaB in synovia affected by RA. 2. CYLD expression significantly decreased in RA-FLSs compared with OA-FLSs. 3. CYLD suppression enhanced the production of pro-inflammatory cytokines, MMPs, and RANKL by activating NF-kappaB in RA-FLSs. 4. CYLD suppression enhanced proliferation, reduced apoptosis, and increased cell division of RA-FLSs and aggravated the activity of NF-kappaB in RA FLSs. CONCLUSIONS: Via its regulation of NF-kappaB activation, CYLD may be involved in the pathogenesis of synovial inflammation in RA as well as in the pro inflammatory effects and hyperproliferation of RA-FLSs. CYLD may therefore provide a potential target for the treatment of RA. PMID- 30285831 TI - Haemoglobin concentration following postpartum haemorrhage and the association between blood transfusion and breastfeeding: a retrospective cohort study. AB - OBJECTIVE: The aim of this study was to determine the association between red blood cell transfusion and breastfeeding among women who have suffered a postpartum haemorrhage at birth taking into account post-birth haemoglobin concentrations. RESULTS: Among 15,451 maternities with postpartum haemorrhage in New South Wales public hospitals between 2007 and 2010, 1828 (12%) received a red cell transfusion. Among transfused women, 686 (38%) had haemoglobin concentration pre-transfusion < 70 g/L, 792 (43%) had 70-90 g/L, and 350 (19%) had > 90 g/L. Rates and adjusted relative risks (aRR) for breastfeeding at hospital discharge were as follows: for women with haemoglobin concentrations < 70 g/L following birth and received a transfusion, 78.6% were breastfeeding and the aRR of breastfeeding compared to untransfused women was 0.90 (99% confidence interval (CI) 0.86-0.95); for women with haemoglobin concentrations 70-90 g/L, 81.3% were breastfeeding, aRR 0.94 (99% CI 0.90-0.98); and for women with haemoglobin concentrations > 90 g/L, 80.9% were breastfeeding, aRR 0.94 (99% CI 0.88-1.00). PMID- 30285833 TI - Intestinal parasitosis and associated factors among diabetic patients attending Arba Minch Hospital, Southern Ethiopia. AB - OBJECTIVE: Local assessment of the magnitude of intestinal parasitic infections and associated factors among diabetic patients helps for good prognosis of diabetes. Hospital based cross-sectional study was conducted by recruiting 215 diabetic patients. A structured questionnaire was used to capture data about socio-demographic characteristics, clinical history and factors associated with intestinal parasitosis. Stool samples were collected and processed by direct wet mount, formol-ether concentration and modified ziehl-Neelson staining techniques. All data were analyzed using Statistical Package for Social Sciences software version 20. RESULTS: The rate of intestinal parasitic infection among diabetic patients was 19.5%. Cryptosporidium parvum accounts the highest frequency (18, 8.4%) followed by Ascaris lumbricoides (8, 3.7%). Presence of domestic animals in the house (AOR = 2.857, 95% CI 1.290-6.330, p = 0.010), manifestation of abdominal pain (AOR = 3.716, 95% CI 1.632-8.459, p = 0.002) and farmer and labor occupation (AOR = 3.695, 95% CI 1.082-12.618, p = 0.037) were significantly associated with intestinal parasitosis. The magnitude of intestinal parasitosis among diabetic patients attending Arba Minch Hospital was considerable. Hence, we recommend routine screening and prompt treatment for intestinal parasitosis in order to improve the health of diabetic patients. PMID- 30285832 TI - Notch2 signal is required for the maintenance of canine hemangiosarcoma cancer stem cell-like cells. AB - BACKGROUND: Hemangiosarcoma (HSA) is a malignant tumor derived from endothelial cells which usually shows poor prognosis due to its high invasiveness, metastatic rate and severe hemorrhage from tumor ruptures. Since the pathogenesis of HSA is not yet complete, further understanding of its molecular basis is required. RESULTS: Here, we identified Notch2 signal as a key factor in maintaining canine HSA cancer stem cell (CSC)-like cells. We first cultured HSA cell lines in adherent serum-free condition and confirmed their CSC-like characteristics. Notch signal was upregulated in the CSC-like cells and Notch signal inhibition by a gamma-secretase inhibitor significantly repressed their growth. Notch2, a Notch receptor, was highly expressed in the CSC-like cells. Constitutive activation of Notch2 increased clonogenicity and number of cells which were able to survive in serum-free condition. In contrast, inhibition of Notch2 activity showed opposite effects. These results suggest that Notch2 is an important factor for maintaining HSA CSC-like cells. Neoplastic cells in clinical cases also express Notch2 higher than endothelial cells in the normal blood vessels in the same slides. CONCLUSION: This study provides foundation for further stem cell research in HSA and can provide a way to develop effective treatments to CSCs of endothelial tumors. PMID- 30285835 TI - Reduced fetal movement intervention Trial-2 (ReMIT-2): protocol for a pilot randomised controlled trial of standard care informed by the result of a placental growth factor (PlGF) blood test versus standard care alone in women presenting with reduced fetal movement at or after 36+ 0 weeks gestation. AB - BACKGROUND: Forty percent of babies who are stillborn born die after 36 weeks gestation and have no lethal structural abnormality. Maternal perception of reduced fetal movement (RFM) is associated with stillbirth and is related to abnormal placental structure and function. The ultimate objective of this trial is to assess whether for women with RFM, intervention directed by measurement of placental biochemical factors in addition to standard care improves pregnancy outcome compared with standard care alone. This is the protocol for a pilot trial to determine the feasibility of a definitive trial and also provide proof of concept that informing care by measurement of placental factors improves neonatal outcomes. METHODS: ReMIT-2 is a multicentre, pilot randomised controlled trial of care informed by results of an additional placental factor blood test versus standard care alone for women presenting with RFM at or after 36+ 0 weeks gestation. Participants will be randomised 1:1 to the intervention arm where the blood test result is revealed and acted on, or to the control arm where the blood sample is not tested immediately and therefore the result cannot be acted on. All participants will be followed up six weeks after delivery to assess their health status and views of the trial, along with healthcare costs. A sub-group will be interviewed within 16 weeks after delivery to further explore their views of the trial. Outcomes to determine feasibility of a definitive trial include number of potentially eligible women, proportion lost to follow-up, clinical characteristics at randomisation, reasons for non-recruitment, compliance with the trial intervention and views of participants and clinicians about the trial. Proof of concept outcomes include: rates of induction of labour; Caesarean birth; and a composite neonatal outcome of stillbirths and deaths before discharge, 5 min Apgar score < 7, umbilical artery pH < 7.05 and admission to neonatal unit for > 48 h. DISCUSSION: Results from this pilot trial will help determine whether a large definitive trial is feasible. Such a study would provide evidence to guide management of women with RFM and reduce stillbirths. TRIAL REGISTRATION: ISRCTN Registry, ISRCTN12067514 . Registered on 8 September 2017. PMID- 30285836 TI - Functional validation of human-specific PowerPlex(r) 21 System (Promega, USA) in chimpanzee (Pan troglodytes). AB - OBJECTIVE: This study was aimed to test the PowerPlex(r) 21 System (Promega, USA), used for human identification applications for its positive cross-species applicability in Chimpanzees (Pan troglodytes) in order to identify heterologous STRs which can be used for individual identification, paternity testing, relatedness establishment and reconstruction of pedigrees and studbook records for captive and wild chimpanzee breeding populations. RESULTS: Of 21 STRs in PowerPlex(r) 21 System (Promega, USA), 19 loci amplified and found to be polymorphic. Locus Aml showed differential banding patterns in males and females similar to those seen for humans and correctly assigned sexes of known identity. Altogether, 58 different alleles were found with an average 3.05 +/- 0.28 alleles per locus. Mean observed (Ho), and expected heterozygosity (He) were 0.93 +/- 0.03 and 0.52 +/- 0.05, respectively. PMID- 30285834 TI - Toward population specific and personalized treatment of Helicobacter pylori infection. AB - In the face of rising prevalence of antibiotic resistance, susceptibility testing to provide personalized treatment is recommended prior to eradication therapy for Helicobacter pylori (H. pylori). Yet, population specific treatment according to the local prevalence of antibiotic resistance may be an alternative if susceptibility testing is not available. In this article, we reviewed the global prevalence of primary antibiotic resistance and the efficacies of commonly used regimens in antibiotic susceptible and resistance strains. We then constructed a model to predict the efficacies of these regimens and proposed an algorithm to choose the optimal first-line and rescue therapies according to the prevalence of antibiotic resistance. Clarithromycin-based therapy (triple, sequential, concomitant, and hybrid therapies) for 14 days remains the treatment of choice in regions with low clarithromycin resistance (<=15%) and bismuth quadruple therapy may be an alternative therapy. In regions with high clarithromycin resistance (> 15%), bismuth quadruple therapy is the treatment of choice and non-bismuth quadruple therapy may be an alternative. Either levofloxacin-based therapy or bismuth quadruple therapy may be used as second-line rescue therapy for patients fail after clarithromycin-based therapies, whereas levofloxacin-based therapy may be used for patients fail after bismuth quadruple therapy. Susceptibility testing or genotypic resistance should be determined after two or more eradication failures. However, empirical therapy according to prior medication history to avoid the empirical reuse of levofloxacin and clarithromycin may be an acceptable alternative after consideration of cost, patient preference, and accessibility. Rifabutin-based therapy for 14 days may serve as the fourth-line therapy. New antibiotics specific for H. pylori are highly anticipated. PMID- 30285838 TI - Detection of virus-specific polymeric immunoglobulin A in acute hepatitis A, C, E virus serum samples using novel chimeric secretory component. AB - OBJECTIVE: To conduct a proof-of-concept study on preferential binding of polymeric IgA (pIgA) using a novel recombinant rabbit/human chimeric secretory component (cSC) and preliminary assessment of the diagnostic potential of virus specific pIgA in discriminating acute hepatitis A, E, and C (HAV, HEV, HCV) patients and uninfected controls using an indirect enzyme-linked immunoassay. RESULTS: cSC binds > 0.06 MUg/ml of purified human and mouse pIgA with negligible cross-reactivity against IgM and IgA. Virus-specific pIgA was significantly higher in serum of acute HAV (n = 6) and HEV (n = 12) patients than uninfected samples (HEV: p < 0.001; HAV: p = 0.001), and had low correlation with virus specific IgM (HEV r: - 0.25, 95% CI - 0.88 to 0.71, p = 0.636; HAV r: 0.05, 95% CI - 0.54 to 0.60, p: 0.885). Anti-HCV pIgA peaked early in HCV seroconversion panels (n = 14), and was undetectable after 4 weeks post-primary bleed, even in ongoing infections, while serum anti-HCV IgA, IgG and IgM persisted. Patients with early acute HCV infection had significantly higher levels of anti-HCV pIgA compared to those with chronic infections (p < 0.01). The use of novel cSC demonstrates the presence of virus-specific pIgA in sera of patients with acute HAV, HEV, and HCV infection, and posits its potential utility as a diagnostic biomarker that warrants further validation on larger sample populations. PMID- 30285839 TI - Outcome measures in clinical trials of treatments for acute severe haemorrhage. AB - BACKGROUND: Acute severe haemorrhage is a common complication of injury, childbirth, surgery, gastrointestinal pathologies and other medical conditions. Bleeding is a major cause of death, but patients also die from non-bleeding causes, the frequency of which varies by the site of haemorrhage and between populations. Because patients can bleed to death within hours, established interventions inevitably take priority over randomisation into a trial. These circumstances raise challenges in selecting appropriate outcome measures for clinical trials of haemostatic interventions. MAIN BODY: We use data from three large randomised controlled trials in acute severe haemorrhage (CRASH-2, WOMAN and HALT-IT) to explore the strengths and limitations of outcome measures commonly used in trials of haemostatic treatments, including all-cause and cause specific mortality, blood transfusion and surgical interventions. Many deaths following acute severe haemorrhage are due to patient comorbidities or complications rather than bleeding. If non-bleeding deaths are unaffected by a haemostatic intervention, even large trials will have low power to detect an effect on all-cause mortality. Due to the dilution from deaths unaffected or reduced by the trial treatment, all-cause mortality can also obscure important harmful effects. Additionally, because the relative contributions of different causes of death vary within and between patient populations, all-cause mortality is not generalisable. Different causes of death occur at different time intervals from bleeding onset, with bleeding deaths generally occurring early. Time specific mortality can therefore be used as a proxy for cause in un-blinded trials where bias is a concern or in situations where cause of death cannot be assessed. Urgent treatment is critical, and so post-randomisation blood transfusion and surgery are often planned before or at the time of randomisation and therefore cannot be influenced by the trial treatment. CONCLUSIONS: All-cause mortality has low power, lacks generalisability and can obscure harmful effects. Cause-specific mortality, such as death due to bleeding or thrombosis, avoids these drawbacks. In certain scenarios, time-specific mortality can be used as a proxy for cause-specific mortality. Blood transfusion and surgical procedures have limited utility as outcome measures in trials of haemostatic treatments. PMID- 30285840 TI - Codon-optimized DsRed fluorescent protein for use in Mycobacterium tuberculosis. AB - OBJECTIVE: We have previously codon-optimized a number of red fluorescent proteins for use in Mycobacterium tuberculosis (mCherry, tdTomato, Turbo-635). We aimed to expand this repertoire to include DsRed, another widely used and flexible red fluorescent protein. RESULTS: We generated expression constructs with a full length DsRed under the control of one of three strong, constitutive promoters (Phsp60, PrpsA or PG13) for use in mycobacteria. We confirmed that full length DsRed (225 amino acids) was expressed and fluoresced brightly. In contrast to mCherry, truncated versions of DsRed lacking several amino acids at the N terminus were not functional. Thus, we have expanded the repertoire of optimized fluorescent proteins for mycobacteria. PMID- 30285837 TI - Leishmaniasis and glycosaminoglycans: a future therapeutic strategy? AB - Leishmania spp. depend on effective macrophage infection to establish and develop in mammalian hosts. Both metacyclic promastigotes and amastigotes are able to infect host cells, and thus they rely on several ligands that, when recognized by macrophage receptors, mediate parasite uptake. During macrophage primary infection with metacyclic forms from the insect vector and during amastigote dissemination via macrophage rupture, both infective stages have to cope with the host extracellular microenvironment, including extracellular matrix molecules. Glycosaminoglycans are abundant in the extracellular matrix and many of these molecules are able to interact with the parasite and the host cell, mediating positive and negative effects for the infection, depending on their structure and/or location. In addition, glycosaminoglycans are present at the surface of macrophages as proteoglycans, playing important roles for parasite recognition and uptake. In this review, we discuss glycosaminoglycans in the context of Leishmania infection as well as the possible applications of the current knowledge regarding these molecules for the development of new therapeutic strategies to control parasite dissemination. PMID- 30285841 TI - Increase of circulating memory B cells after glucocorticoid-induced remission identifies patients at risk of IgG4-related disease relapse. AB - BACKGROUND: Immunoglobulin G4-related disease (IgG4-RD) promptly responds to glucocorticoids but relapses in a considerable fraction of patients. Reliable biomarkers of flare are currently lacking because the pathophysiology of IgG4-RD remains largely elusive. In the present work, we aimed to identify perturbations of B-cell subpopulations that might predict IgG4-RD relapse. METHODS: Thirty patients were treated with glucocorticoids according to international guidelines. Circulating CD19+ and CD20+ cells, naive B cells, memory B cells, plasmablasts, and plasma cells were measured by flow cytometry at baseline and every 6 months for 2 years after the initiation of corticosteroid therapy. RESULTS: Patients with active untreated IgG4-RD showed significantly reduced CD19+ B cells, CD20+ B cells, and naive B cells compared with healthy subjects (p < 0.05), but significantly expanded plasmablasts and plasma cells (p < 0.01). After 6 months of corticosteroid treatment, all patients achieved clinical improvement. Naive B cells, plasmablasts, and plasma cells significantly decreased compared with disease onset, whereas memory B cells significantly increased compared with baseline (p < 0.01). Increase of memory B cells was observed only in patients who relapsed within 2 years of follow-up, however (HR, 12.24; 2.99 to 50.2; p = 0.0005). In these patients, the relapse rates at 12 and 24 months were 30% and 100%, respectively. No abnormalities of other B-cell subpopulations at disease onset or after 6 months of glucocorticoid treatment were found to predict IgG4-RD relapse at 2 years. CONCLUSIONS: Increase of circulating memory B cells after 6 months of glucocorticoid treatment might predict IgG4-RD relapse. PMID- 30285842 TI - Are gender-specific approaches needed in diagnosing early axial spondyloarthritis? Data from the SPondyloArthritis Caught Early cohort. AB - BACKGROUND: Although gender differences have been observed in the severity of axial spondyloarthritis (axSpA), gender differences in disease presentation of early axSpA have not been thoroughly investigated. In particular, their impact on the diagnostic process is unknown. METHODS: Baseline data from the SPondyloArthritis Caught Early cohort, which includes patients with chronic back pain (CBP; duration >= 3 months and <= 2 years, age of onset < 45 years), were analysed. Patients underwent a full diagnostic work-up, including MRI and radiograph of the sacroiliac joints (MRI-SIJ and X-SIJ), to establish a diagnosis of axSpA. Characteristics of male and female patients with a certain diagnosis of axSpA (confidence level by the physician >= 7 on a 0-10 rating scale) were compared. Regression models were built for: the whole CBP cohort stratified by gender, to study which SpA features were associated most with diagnosis in each gender; and for axSpA patients, to test whether gender was associated with imaging positivity (MRI-SIJ+ and/or X-SIJ+). RESULTS: Of the 719 CBP patients, 275 were male. With 146/275 males and 155/444 females diagnosed as axSpA, males were more likely to be diagnosed with axSpA (OR 2.1, 95% CI 1.5-2.9). Despite similar symptom duration, male axSpA patients were younger at diagnosis (27.4 +/- 7.5 vs 29.5 +/- 7.8 years; p = 0.02). Presence of SpA features was similar in male and female axSpA patients, except for HLA-B27 and imaging positivity that were more common in male axSpA patients (80% vs 60%; p < 0.01 and 78% vs 64%; p = 0.01). Nevertheless, these SpA features were still more prevalent in female axSpA patients than in no-axSpA patients, both females (HLA-B27+ 23%, positive imaging 7%) and males (HLAB27+ 34%, positive imaging 11%) (all p < 0.01). Moreover, in multivariable models with diagnosis of axSpA as outcome, HLA-B27 and imaging positivity were associated with the diagnosis in both sexes. In models with imaging positivity as outcome, male gender and HLA-B27 were both independently associated with MRI+ and/or X-SI+. CONCLUSIONS: While our data show clear gender differences in early axSpA, they highlight that HLA-B27 and imaging are still key elements for diagnosis in both genders. Our study does not suggest that separate diagnostic strategies for men and women are required. PMID- 30285843 TI - Draft genome sequence of Staphylococcus sp. EZ-P03 isolated from a mesophilic anaerobic digester. AB - OBJECTIVES: Staphylococcus species of the family Staphylococcaceae are facultatively anaerobic Gram-positive cocci growing in clusters, pairs and occasionally in short chains. Staphylococci can be detected in different environments. They are common commensals, but some can also cause infections in humans. Hence, their investigation is required to understand ecology and genetics and to create an opportunity for comparative studies. DATA DESCRIPTION: In this study, we report the determination of a draft genome sequence of Staphylococcus sp. strain EZ-P03 which was isolated from anaerobically digested chicken waste materials. The draft genome of Staphylococcus sp. EZ-P03 constituted a total of 62 contigs (> 500 bp) amounting to 2,689,358 bp with a G+C content of 37.3% and a N50 contig size of 126,562 bp. The whole genome shotgun project of Staphylococcus sp. strain EZ-P03 has been deposited at DDBJ/ENA/GenBank under the accession number QPMO00000000. PMID- 30285844 TI - Activity levels of female Triatoma infestans change depending on physiological condition. AB - BACKGROUND: Triatoma infestans (Hemiptera: Reduviidae) is the main vector of Trypanosoma cruzi, the etiological agent of Chagas disease, in South America. Active dispersal of this vector is the principal cause of recolonization of human dwellings previously treated with insecticides. Due to the persistence of vector populations and their movement between habitats, dispersive behavior studies are important for understanding the epidemiology of Chagas disease. The aim of this study was to analyze the relationship among T. infestans females' activity levels according to their physiological conditions. RESULTS: Two groups of insects were used, unfed and fed females. Each was composed of three subgroups in relation to the reproductive state: fifth-stage nymphs, virgin and fertilized females. There was a significant interaction between reproductive and nutritional states among T. infestans female' activity levels. During the experiments, unfed and fed nymphs remained inactive. Virgin females showed a dual behavior in their movement; fasted insects were more active. Fertilized females, both fed and unfed, were always active. CONCLUSION: The reproductive and nutritional conditions of T. infestans females affect their activity levels. When females with different reproductive states remained together, fertilized females showed permanent activity levels, suggesting that this subgroup of females represents the highest epidemiological risk as colonizers of human dwellings. PMID- 30285845 TI - Is synovial hypertrophy without Doppler activity sensitive to change? Post-hoc analysis from a rheumatoid arthritis ultrasound study. AB - BACKGROUND: To explore to what extent synovial hypertrophy in joints without Doppler activity is a sign of active disease, we investigated the sensitivity to change of synovial hypertrophy without Doppler activity during biological disease modifying antirheumatic drug (bDMARD) treatment in rheumatoid arthritis (RA) patients. METHOD: RA patients initiating or switching bDMARD treatment had ultrasound (US) performed on 36 joints at baseline, and at 3 and 6 months. Synovial hypertrophy by grayscale US and Doppler activity were graded separately from 0 to 3 at the joint level for all time points. Changes in synovial hypertrophy in joints without Doppler activity during treatment were assessed and compared with changes in synovial hypertrophy in joints with Doppler activity. RESULTS: We included 151 patients (82.8% women, 80.1% seropositive for anticyclic citrullinated peptide) with a mean +/- standard deviation age of 51.4 +/- 13.2 years, a disease duration of 9.9 +/- 7.9 years, and baseline Disease Activity Score 28-joint count C-reactive peptide (DAS28-CRP) of 4.14 +/- 1.32. At baseline, 44.8% of all joints examined (n = 5225) had synovial hypertrophy >= 1 and 50.7% of these had synovial hypertrophy without Doppler activity. The improvement in synovial hypertrophy was similar in joints with and without Doppler activity but, when adjusting for the baseline score of synovial hypertrophy, joints with synovial hypertrophy without Doppler had a higher tendency towards a decrease than joints with synovial hypertrophy with Doppler activity independent of grade (3 months: p < 0.0001; 6 months: p = 0.0003). CONCLUSION: Joints with synovial hypertrophy without Doppler activity improve during treatment, independent of the grade. Thus, SH without Doppler activity is not a sign of inactive disease. These findings indicate that joints with synovial hypertrophy without Doppler activity should also be taken in to account when assessing disease activity by US. PMID- 30285847 TI - Comorbidities and the referral pathway to access joint replacement surgery: an exploratory qualitative study. AB - BACKGROUND: Variation in access to joint replacement surgery has been widely reported but less attention has been given to the impact of comorbidities on the patient journey to joint replacement surgery. There is a lack of consensus amongst healthcare professionals and commissioners about how patients with comorbidities should be referred or selected for joint replacement surgery. It is therefore important to understand the views of healthcare professionals on the management, referral and selection of patients with comorbidities for joint replacement surgery. METHODS: An exploratory qualitative study involving semi structured interviews with 20 healthcare professionals in England across the referral pathway to joint replacement surgery. They were asked to talk about their experiences of referring and selecting patients with comorbidities for joint replacement surgery. The interviews were audio-recorded and transcribed verbatim. Data analysis followed a thematic analysis approach based on the principles of grounded theory. RESULTS: In general, the presence of comorbidities was not seen as a barrier to being referred or selected for joint replacement but was seen as a challenge to manage the patients' journey across the referral pathway. Each professional group, concentrated on different aspects of the patients' condition which appeared to affect how they managed patients with comorbidities. This implied there was a disagreement about roles and responsibilities in the management of patients with comorbidities. None of the professionals believed it was their responsibility to address comorbidities in preparation for surgery. This disagreement was identified as a reason why some patients seem to 'get lost' in the referral system when they were considered to be unprepared for surgery. Patients were then potentially left to manage their own comorbidities before being reconsidered for joint replacement. CONCLUSIONS: At the clinician-level, comorbidities were not perceived as a barrier to accessing joint replacement surgery but at the pathway-level, it may create an implicit barrier such that patients with comorbidities may get 'lost' to the system. Further study is needed to explore the roles and responsibilities of professionals across the current orthopaedic referral pathway which may be less suitable for patients with comorbidities. PMID- 30285846 TI - UBN1/2 of HIRA complex is responsible for recognition and deposition of H3.3 at cis-regulatory elements of genes in mouse ES cells. AB - BACKGROUND: H3.3 is an ancient and conserved H3 variant and plays essential roles in transcriptional regulation. HIRA complex, which is composed of HIRA, UBN1 or UBN2, and Cabin1, is a H3.3 specific chaperone complex. However, it still remains largely uncharacterized how HIRA complex specifically recognizes and deposits H3.3 to the chromatin, such as promoters and enhancers. RESULTS: In this study, we demonstrate that the UBN1 or UBN2 subunit is mainly responsible for specific recognition and direct binding of H3.3 by the HIRA complex. While the HIRA subunit can enhance the binding affinity of UBN1 toward H3.3, Cabin1 subunit cannot. We also demonstrate that both Ala87 and Gly90 residues of H3.3 are required and sufficient for the specific recognition and binding by UBN1. ChIP seq studies reveal that two independent HIRA complexes (UBN1-HIRA and UBN2-HIRA) can cooperatively deposit H3.3 to cis-regulatory regions, including active promoters and active enhancers in mouse embryonic stem (mES) cells. Importantly, disruption of histone chaperone activities of UBN1 and UBN2 by FID/AAA mutation results in the defect of H3.3 deposition at promoters of developmental genes involved in neural differentiation, and subsequently causes the failure of activation of these genes during neural differentiation of mES cells. CONCLUSION: Together, our results provide novel insights into the mechanism by which the HIRA complex specifically recognizes and deposits H3.3 at promoters and enhancers of developmental genes, which plays a critical role in neural differentiation of mES cells. PMID- 30285848 TI - Factor analysis of the Clinical Outcomes in Routine Evaluation - Outcome Measures (CORE-OM) in a Kenyan sample. AB - BACKGROUND: There is no generic psychotherapy outcome measure validated for Kenyan populations. The objective of this study was to test the acceptability and factor structure of the Clinical Outcomes in Routine Evaluation - Outcome Measure in patients attending psychiatric clinics at two state-owned hospitals in Nairobi. METHODS: Three hundred and forty-five patients filled out the CORE-OM after their initial therapy session. Confirmatory and Exploratory Factor Analysis (CFA/EFA) were used to study the factor structure of the CORE-OM. RESULTS: The English version of the CORE-OM seemed acceptable and understandable to psychiatric patients seeking treatment at the state-owned hospitals in Nairobi. Factor analyses showed that a model with a general distress factor, a risk factor, and a method factor for positively framed items fit the data best according to both CFA and EFA analysis. Coefficient Omega Hierarchical showed that the general distress factor was reliably measured even if differential responding to positively framed items was regarded as error variance. CONCLUSIONS: The English language version of the CORE-OM can be used with psychiatric patients attending psychiatric treatment in Nairobi. The factor structure was more or less the same as has been shown in previous studies. The most important limitation is the relatively small sample size. PMID- 30285849 TI - An expanded global inventory of allelic variation in the most extremely polymorphic region of Plasmodium falciparum merozoite surface protein 1 provided by short read sequence data. AB - BACKGROUND: Within Plasmodium falciparum merozoite surface protein 1 (MSP1), the N-terminal block 2 region is a highly polymorphic target of naturally acquired antibody responses. The antigenic diversity is determined by complex repeat sequences as well as non-repeat sequences, grouping into three major allelic types that appear to be maintained within populations by natural selection. Within these major types, many distinct allelic sequences have been described in different studies, but the extent and significance of the diversity remains unresolved. METHODS: To survey the diversity more extensively, block 2 allelic sequences in the msp1 gene were characterized in 2400 P. falciparum infection isolates with whole genome short read sequence data available from the Pf3K project, and compared with the data from previous studies. RESULTS: Mapping the short read sequence data in the 2400 isolates to a reference library of msp1 block 2 allelic sequences yielded 3815 allele scores at the level of major allelic family types, with 46% of isolates containing two or more of these major types. Overall frequencies were similar to those previously reported in other samples with different methods, the K1-like allelic type being most common in Africa, MAD20-like most common in Southeast Asia, and RO33-like being the third most abundant type in each continent. The rare MR type, formed by recombination between MAD20-like and RO33-like alleles, was only seen in Africa and very rarely in the Indian subcontinent but not in Southeast Asia. A combination of mapped short read assembly approaches enabled 1522 complete msp1 block 2 sequences to be determined, among which there were 363 different allele sequences, of which 246 have not been described previously. In these data, the K1-like msp1 block 2 alleles are most diverse and encode 225 distinct amino acid sequences, compared with 123 different MAD20-like, 9 RO33-like and 6 MR type sequences. Within each of the major types, the different allelic sequences show highly skewed geographical distributions, with most of the more common sequences being detected in either Africa or Asia, but not in both. CONCLUSIONS: Allelic sequences of this extremely polymorphic locus have been derived from whole genome short read sequence data by mapping to a reference library followed by assembly of mapped reads. The catalogue of sequence variation has been greatly expanded, so that there are now more than 500 different msp1 block 2 allelic sequences described. This provides an extensive reference for molecular epidemiological genotyping and sequencing studies, and potentially for design of a multi-allelic vaccine. PMID- 30285850 TI - Recruiting care homes to a randomised controlled trial. AB - BACKGROUND: There are more than a quarter of a million individuals aged >= 65 years who are resident in care homes in England and Wales. Care home residents have high levels of cognitive impairment, physical disability, multimorbidity and polypharmacy. Research is needed to ensure there are robust, evidence-based interventions to improve the quality of life of this frail group. However, there is a paucity of research studies in this area. Recruiting care homes and their residents to research is challenging. A feasibility, cluster randomised controlled trial was undertaken as part of a research programme to identify ways to develop and test methods to enhance the physical activity of care home residents. This paper describes two methods of recruiting care homes to the trial and draws out learning to inform future studies. METHODS: Eligible care homes met the following criteria: they were within a defined geographical area in the north of England; provided residential care for adults >= 65 years of age; had not previously been involved in the research programme; were not taking part in a conflicting study; were not recorded on the Care Quality Commission website as 'inadequate' or 'requiring improvements' in any area; and had >= 10 beds. Care homes were identified by a 'systematic approach' using the Care Quality Commission website database of care homes or a 'targeted approach' via a network of research-ready care homes. A standardised method was used to recruit care homes including eligibility screening; invitation letters; telephone contact; visits; formal letter of agreement. RESULTS: In the systematic approach, 377 care homes were screened, 230 (61%) were initially eligible and invited to participate, 11 were recruited (recruitment rate (RR) 4.8%). In the targeted approach, 15 care homes were invited to participate, two were recruited (RR 13.3%). Overall, 245 care homes were approached and 13 recruited (RR 5.3%). A variety of care homes were recruited to the trial in terms of size, location, ownership and care provision. CONCLUSIONS: Systematic recruitment of care homes to the study was time-consuming and resource-heavy but led to a variety of care homes being recruited. The targeted approach led to a higher recruitment rate. TRIAL REGISTRATION: ISRCTN registry, ISRCTN16076575 . Registered on 25 June 2015. PMID- 30285851 TI - Hidden in plain sight-highly abundant and diverse planktonic freshwater Chloroflexi. AB - BACKGROUND: Representatives of the phylum Chloroflexi, though reportedly highly abundant in the extensive deep water habitats of both marine (SAR202 up to 30% of total prokaryotes) and freshwater (CL500-11 up to 26% of total prokaryotes), remain uncultivated and uncharacterized. There are few metagenomic studies on marine Chloroflexi representatives, while the pelagic freshwater Chloroflexi community is largely unknown except for a single metagenome-assembled genome of CL500-11. RESULTS: Here, we provide the first extensive examination of the community composition of this cosmopolitan phylum in a range of pelagic habitats (176 datasets) and highlight the impact of salinity and depth on their phylogenomic composition. Reconstructed genomes (53 in total) provide a perspective on the phylogeny, metabolism, and distribution of three novel classes and two family-level taxa within the phylum Chloroflexi. We unraveled a remarkable genomic diversity of pelagic freshwater Chloroflexi representatives that thrive not only in the hypolimnion as previously suspected, but also in the epilimnion. Our results suggest that the lake hypolimnion provides a globally stable habitat reflected in lower species diversity among hypolimnion-specific CL500-11 and TK10 clusters in distantly related lakes compared to a higher species diversity of the epilimnion-specific SL56 cluster. Cell volume analyses show that the CL500-11 are among the largest prokaryotic cells in the water column of deep lakes and with a biomass to abundance ratio of two they significantly contribute to the deep lake carbon flow. Metabolic insights indicate participation of JG30-KF-CM66 representatives in the global cobalamin production via cobinamide to cobalamin salvage pathway. CONCLUSIONS: Extending phylogenomic comparisons to brackish and marine habitats suggests salinity as the major influencer of the community composition of the deep-dwelling Chloroflexi in marine (SAR202) and freshwater (CL500-11) habitats as both counterparts thrive in intermediate brackish salinity; however, freshwater habitats harbor the most phylogenetically diverse community of pelagic Chloroflexi representatives that reside both in epi- and hypolimnion. PMID- 30285852 TI - Multidimensional, quantitative assessment of PD-1/PD-L1 expression in patients with Merkel cell carcinoma and association with response to pembrolizumab. AB - BACKGROUND: We recently reported a 56% objective response rate in patients with advanced Merkel cell carcinoma (MCC) receiving pembrolizumab. However, a biomarker predicting clinical response was not identified. METHODS: Pretreatment FFPE tumor specimens (n = 26) were stained for CD8, PD-L1, and PD-1 by immunohistochemistry/immunofluorescence (IHC/IF), and the density and distribution of positive cells was quantified to determine the associations with anti-PD-1 response. Multiplex IF was used to test a separate cohort of MCC archival specimens (n = 16), to identify cell types expressing PD-1. RESULTS: Tumors from patients who responded to anti-PD-1 showed higher densities of PD-1+ and PD-L1+ cells when compared to non-responders (median cells/mm2, 70.7 vs. 6.7, p = 0.03; and 855.4 vs. 245.0, p = 0.02, respectively). There was no significant association of CD8+ cell density with clinical response. Quantification of PD-1+ cells located within 20 MUm of a PD-L1+ cell showed that PD-1/PD-L1 proximity was associated with clinical response (p = 0.03), but CD8/PD-L1 proximity was not. CD4+ and CD8+ cells in the TME expressed similar amounts of PD-1. CONCLUSIONS: While the binomial presence or absence of PD-L1 expression in the TME was not sufficient to predict response to anti-PD-1 in patients with MCC, we show that quantitative assessments of PD-1+ and PD-L1+ cell densities as well as the geographic interactions between these two cell populations correlate with clinical response. Cell types expressing PD-1 in the TME include CD8+ T-cells, CD4+ T-cells, Tregs, and CD20+ B-cells, supporting the notion that multiple cell types may potentiate tumor regression following PD-1 blockade. PMID- 30285854 TI - Racial differences in comorbidity profile among patients with chronic obstructive pulmonary disease. AB - BACKGROUND: Chronic obstructive pulmonary disease (COPD) is often accompanied by multiple comorbidities, which are associated with an increased risk of exacerbation, a poor health-related quality of life, and high mortality. However, differences in comorbidity profile by race and ethnicity in COPD patients have not been fully elucidated. METHODS: Participants aged 40 to 79 years with spirometry-defined COPD from the U.S. National Health and Nutrition Examination Survey (NHANES) (2007-2012) and from the Korea NHANES (2007-2015) were analyzed to compare the prevalence of comorbidities by race and ethnicity group. Comorbidities were defined using questionnaire data, physical exams, and laboratory tests. RESULTS: Non-Hispanic Whites had the highest prevalence of dyslipidemia (65.5%), myocardial infarction (6.2%), osteoarthritis (40.1%), and osteoporosis (13.6%), while non-Hispanic Blacks had the highest prevalence of asthma (24.0%), hypertension (70.2%), stroke (7.3%), diabetes mellitus (DM) (23.3%), anemia (16.4%), and rheumatoid arthritis (11.9%). Compared to non Hispanic Whites, non-Hispanic Blacks had a significantly higher prevalence of hypertension, stroke, DM, anemia, and rheumatoid arthritis after adjusting for age, sex, body mass index, and smoking status, while Hispanics had a significantly higher prevalence of DM and anemia, and Koreans had significantly lower prevalences of all comorbidities except stroke, DM, and anemia. CONCLUSIONS: COPD-related comorbidities varied significantly by race and ethnicity, and different strategies may be required for the optimal management of COPD and its comorbidities in different race and ethnicity groups. PMID- 30285853 TI - MiRNA expression profiles in healthy OSAHS and OSAHS with arterial hypertension: potential diagnostic and early warning markers. AB - BACKGROUND: Obstructive sleep apnea-hypopnea syndrome (OSAHS) is prone to being complicated with various cardiovascular, cerebrovascular and metabolic conditions. OSAHS, due to its multifactorial nature, entails individualized and comprehensive treatment. So far, no well-established diagnostic criteria for the disease are available. In recent years, miRNA has been shown to be a sensitive biomarker suggestive of the progression and prognosis of many diseases. In this study, we examined some serum miRNAs in healthy OSAHS (OSAHS patients without complication) and OSAHS with arterial hypertension, with an attempt to understand the potential effects on the disease, improve the diagnosis of OSAHS and find OSAHS-related diagnostic markers. METHODS: Against various diagnostic criteria, participants were divided into three groups: healthy OSAHS, OSAHS with arterial hypertension and healthy controls. Their serum miRNA profiles were assessed by microarray technology, and then differentially expressed miRNAs were verified by quantitative real-time PCR (qRT-PCR). The receiver operating characteristic (ROC) curves of miRNAs were constructed and the areas under the curve (AUC) were calculated. Meanwhile, the miRNAs were subjected to logistic regression analysis. The target genes were bioinformatically assessed, their functions and signaling pathways further determined and eventually an miRNA-gene network was established. RESULTS: Analysis with the miRNA array exhibited that, compared with the control group, 12 differentially expressed miRNAs were found in healthy OSAHS, and 33 were found in OSAHS with arterial hypertension. The expression of miR-126-3p, let 7d-5p, miR-7641 and miR-1233-5p, miR-320b, miR-145-5p, miR-107, miR-26a-5p were validated by using qRT-PCR. Bioinformatics analysis predicted that the potential target genes of these miRNAs might be involved in metabolism, and the regulation of endothelial cells and nervous system. Moreover, the ROC analysis showed that the using miR-145-5p and let-7d-5p in combination can identify the healthy OSAHS, presence of miR-126-3p, miR-26a-5p and miR-107 was well indicative of OSAHS with arterial hypertension. CONCLUSIONS: A cluster of dysregulation miRNAs have been found to be involved in the development of OSAHS patients. Moreover, these miRNAs might be used to be potential diagnostic and early warning markers. PMID- 30285855 TI - Salmonella Gallinarum delivering M2eCD40L in protein and DNA formats acts as a bivalent vaccine against fowl typhoid and H9N2 infection in chickens. AB - Fowl typhoid (FT), a septicemic disease caused by Salmonella Gallinarum (SG), and H9N2 influenza infection are two economically important diseases that affect poultry industry worldwide. Herein, we exploited a live attenuated SG mutant (JOL967) to deliver highly conserved extracellular domains of H9N2 M2 (M2e) to induce protective immunity against both H9N2 infection and FT. To increase the immunogenicity of M2e, we physically linked it with CD40L and cloned the fusion gene into either prokaryotic constitutive expression vector pJHL65 or mammalian expression vector pcDNA3.1+. Then pJHL65-M2eCD40L or pcDNA-M2eCD40L recombinant plasmid was electroporated into JOL967 strain and the resultant clones were designated as JOL2074 and JOL2076, respectively. We demonstrated that the chickens vaccinated once orally with a co-mix of JOL2074 and JOL2076 strains elicited significantly (p < 0.05) higher M2e-specific humoral and cell-mediated immunity compared to JOL2074 alone vaccinated group. However, SG-specific immune responses were comparable in both the vaccination groups. On challenge with the virulent H9N2 virus (105 TCID50) at 28th day post-vaccination, chickens that received a co-mix of JOL2074 plus JOL2076 strains exhibited significantly (p < 0.05) lower lung inflammation and viral load in both lungs and cloacal samples than JOL2074 alone vaccinated group. Against challenge with the lethal wild-type SG, both the vaccination groups exhibited only 12.5% mortality compared to 75% mortality observed in the control group. In conclusion, we show that SG delivering M2eCD40L can act as a bivalent vaccine against FT and H9N2 infection and further studies are warranted to develop this SG-M2eCD40L vaccine as a broadly protective vaccine against avian influenza virus subtypes. PMID- 30285856 TI - Durable response to anti-PD-1 immunotherapy in epithelioid angiomyolipoma: a report on the successful treatment of a rare malignancy. AB - BACKGROUND: Malignant angiomyolipoma is an uncommon tumor of the class of perivasciular epithelioid cell neoplasms (PEComas). These tumors are characteristically driven by deleterious mutations in the tumor suppressors TSC1 and TSC2, whose gene products typically act to inhibit mTOR. There are several cases of malignant angiomyolipoma which exhibit transient responses to mTOR inhibitors, forming the basis of current practice guidelines in malignant PEComa. However the tumors ultimately acquire resistance, and there is no well established second-line option. Despite the increasing prevalence of immunotherapy across a wide range of solid tumors, little is known about the immune infiltrate and PD-L1 expression of angiomyolipoma. Furthermore, there is no reported case on the treatment of malignant angiomyolipoma with an immune checkpoint inhibitor. CASE PRESENTATION: A 38 year-old man presented with gross hematuria and was diagnosed with renal epithelioid angiomyolipoma. Despite surgical resection, the tumor recurred and metastasized. Targeted genomic sequencing revealed a deleterious mutation in TSC2, and the patient was treated with the mTOR inihbitor everolimus. The patient went on to have a partial response but ultimately progressed. He was then treated with the anti-PD-1 immune checkpoint inhibitor nivolumab, and achieved a durable near-complete response which is ongoing after two years of treatment. Immunohistochemical staining of tumor tissue revealed strong PD-L1 expression and a brisk T-cell infiltrate. CONCLUSIONS: We report on the first durable systemic treatment of malignant epithelioid angiomyolipoima with the use of PD-1 antibody nivolumab. Given the absence of prospective clinical trials in this exceedingly rare disease, particularly in the second-line setting, immune checkpoint inhibitors like nivolumab should be considered. PMID- 30285857 TI - Comparative analysis of rodent and small mammal viromes to better understand the wildlife origin of emerging infectious diseases. AB - BACKGROUND: Rodents represent around 43% of all mammalian species, are widely distributed, and are the natural reservoirs of a diverse group of zoonotic viruses, including hantaviruses, Lassa viruses, and tick-borne encephalitis viruses. Thus, analyzing the viral diversity harbored by rodents could assist efforts to predict and reduce the risk of future emergence of zoonotic viral diseases. RESULTS: We used next-generation sequencing metagenomic analysis to survey for a range of mammalian viral families in rodents and other small animals of the orders Rodentia, Lagomorpha, and Soricomorpha in China. We sampled 3,055 small animals from 20 provinces and then outlined the spectra of mammalian viruses within these individuals and the basic ecological and genetic characteristics of novel rodent and shrew viruses among the viral spectra. Further analysis revealed that host taxonomy plays a primary role and geographical location plays a secondary role in determining viral diversity. Many viruses were reported for the first time with distinct evolutionary lineages, and viruses related to known human or animal pathogens were identified. Phylogram comparison between viruses and hosts indicated that host shifts commonly happened in many different species during viral evolutionary history. CONCLUSIONS: These results expand our understanding of the viromes of rodents and insectivores in China and suggest that there is high diversity of viruses awaiting discovery in these species in Asia. These findings, combined with our previous bat virome data, greatly increase our knowledge of the viral community in wildlife in a densely populated country in an emerging disease hotspot. PMID- 30285858 TI - The critical interaction between valproate sodium and warfarin: case report and review. AB - BACKGROUND: Valproic acid (VPA) and warfarin are commonly prescribed for patients with epilepsy and concomitant atrial fibrillation (AF). When VPA and warfarin are prescribed together, clinically important interactions may occur. VPA may replace warfarin from the protein binding sites and result in an abnormally increased anticoagulation effect. This is commonly underrecognized. CASE PRESENTATION: In our case, we report a 78-year-old woman with a glioma who presented with status epilepticus. The patient was on warfarin to prevent cardiogenic embolism secondary to AF. Intravenous loading dose of VPA was administered, but international normalized ratio (INR) increased significantly to 8.26. Intravenous vitamin K1 was then given and the patient developed no overt bleeding during the hospitalization. CONCLUSION: By reviewing the literature and discussing the critical interaction between valproate sodium and warfarin, we conclude that intravenous VPA and the co-administrated warfarin may develop critical but underrecognized complications due to effects on the function of hepatic enzymes and displacement of protein binding sites. PMID- 30285860 TI - Assessing the role of virtual reality training in Canadian Otolaryngology-Head & Neck Residency Programs: a national survey of program directors and residents. AB - BACKGROUND: Given mounting pressure of work hour restrictions, resource constraints, and variability of clinical exposure, Otolaryngology-Head & Neck Surgery (OHNS) residency training has shifted away from the apprenticeship model to embrace the Royal College of Physicians and Surgeons of Canada's "Competence by Design" initiative. As a result, appraising both current and potential educational adjuncts has become increasingly important. In this investigation, a national needs assessment survey was performed to identify strengths, weaknesses, and future opportunities of the current training landscape. METHODS: An online survey was distributed to all thirteen Canadian OHNS post-graduate administrators for completion by program directors and residents from February to October in 2016. Prior to distribution, the survey was vetted for face validity by a group of staff Otolaryngologists and questions were modified accordingly. Quantitative analysis was performed on SPSS (IBM Corp., Chicago) with non-parametric, two tailed Mann-Whitney U testing performed on scaled questions. RESULTS: Of the 68 responses, 11 of 13 (84.6%) of program directors and 57 of 168 (33.9%) residents responded to the survey. All 13 programs currently utilize cadaveric laboratory dissections. Associated challenges were ranked as specimen availability, faculty participation, insufficient space, and resident time constraints. 30.8% of programs currently utilize some form of virtual reality simulator, which 90.9% of program directors felt would be a fair and effective platform for evaluation. CONCLUSION: A discrepancy exists between the favourable attitudes of both residents and program directors towards virtual reality simulation and its actual adoption. For successful adoption to occur, the existing barriers to unconventional training must be addressed and the tangible benefits for competency based training will need to be explored. PMID- 30285859 TI - An open-label pilot study on preventing glucocorticoid-induced diabetes mellitus with linagliptin. AB - BACKGROUND: Numerous patients develop diabetes in response to glucocorticoid therapy. This study explored the efficacy, safety, and preventive potential of the dipeptidyl peptidase-4 inhibitor, linagliptin (TRADJENTA(r)), in the development of glucocorticoid-induced diabetes mellitus. METHODS: From December 2014 to November 2015, we recruited non-diabetic Japanese patients scheduled for treatment with daily prednisolone >=20 mg. Enrolled patients had at least one of following risk factors for glucocorticoid-induced diabetes mellitus: estimated glomerular filtration rate <= 60 mL/minute/1.73 m2; age >= 65 years; hemoglobin A1c > 6.0%. A daily dose of 5 mg of linagliptin was administered simultaneously with glucocorticoid therapy. The primary outcome was the development of glucocorticoid-induced diabetes mellitus. Additional orally administered hypoglycemic medications and/or insulin injection therapy was initiated according to the blood glucose level. RESULTS: Four of five patients developed glucocorticoid-induced diabetes mellitus within 1 week of glucocorticoid treatment. For 12 weeks, two of the four patients with glucocorticoid-induced diabetes mellitus required orally administered medications, but no patients required insulin. Blood glucose levels before breakfast and lunch tended to decrease with time; the median glucose levels before breakfast were 93 and 79.5 mg/dL at 1 and 3 weeks, respectively. Two patients experienced mild hypoglycemia around 2 weeks. Glucose levels after lunch remained high throughout all 4 weeks despite decreasing the glucocorticoid dosage. CONCLUSIONS: Linagliptin may be insufficient to prevent the development of glucocorticoid-induced diabetes mellitus but has the potential to reduce the requirement for insulin injection therapy. Treatment of glucocorticoid-induced diabetes mellitus was continued for at least 1 month and fasting hypoglycemia in early morning should be monitored after 2 weeks. TRIAL REGISTRATION: This trial was registered 02 November 2014 with UMIN Clinical Trials Registry (no. 000015588 ). PMID- 30285862 TI - Assessment of health professional education across five Asian countries-a protocol. AB - BACKGROUND: There is an increasing consensus globally that the education of health professionals is failing to keep pace with scientific, social, and economic changes transforming the healthcare environment. This catalyzed a movement in reforming education of health professionals across Bangladesh, China, India, Thailand, and Vietnam who jointly volunteered to implement and conduct cooperative, comparative, and suitable health professional education assessments with respect to the nation's socio-economic and cultural status, as well as domestic health service system. METHODS: The 5C network undertook a multi-country health professional educational study to provide its countries with evidence for HRH policymaking. Its scope was limited to the assessment of medical, nursing, and public health education at three levels within each country: national, institutional, and graduate level (including about to graduate students and alumni). RESULTS: This paper describes the general issues related to health professional education and the protocols used in a five-country assessment of medical, nursing, and public health education. A common protocol for the situation analysis survey was developed that included tools to undertake a national and institutional assessment, and graduate surveys among about-to graduate and graduates for medical, nursing, and public health professions. Data collection was conducted through a mixture of literature reviews and qualitative research. CONCLUSIONS: The national assessment would serve as a resource for countries to plan HRH-related future actions. PMID- 30285864 TI - The triennial International Pigment Cell Conference (IPCC). AB - The International Federation of Pigment Cell Societies (IFPCS) held its XXIII triennial International Pigment Cell Conference (IPCC) in Denver, Colorado in August 2017. The goal of the summit was to provide a venue promoting a vibrant interchange among leading basic and clinical researchers working on leading-edge aspects of melanocyte biology and disease. The philosophy of the meeting, entitled Breakthroughs in Pigment Cell and Melanoma Research, was to deliver a comprehensive program in an inclusive environment fostering scientific exchange and building new academic bridges. This document provides an outlook on the history, accomplishments, and sustainability of the pigment cell and melanoma research community. Shared progress in the understanding of cellular homeostasis of pigment cells but also clinical successes and hurdles in the treatment of melanoma and dermatological disorders continue to drive future research activities. A sustainable direction of the societies creates an international forum identifying key areas of imminent needs in laboratory research and clinical care and ensures the future of this vibrant, diverse and unique research community at the same time. Important advances showcase wealth and breadth of the field in melanocyte and melanoma research and include emerging frontiers in melanoma immunotherapy, medical and surgical oncology, dermatology, vitiligo, albinism, genomics and systems biology, precision bench-to-bedside approaches, epidemiology, pigment biophysics and chemistry, and evolution. This report recapitulates highlights of the federate meeting agenda designed to advance clinical and basic research frontiers from melanoma and dermatological sciences followed by a historical perspective of the associated societies and conferences. PMID- 30285861 TI - Host-microbiome interactions and recent progress into understanding the biology of acne vulgaris. AB - Acne is one of the most common skin diseases worldwide and results in major health care costs and significant morbidity to severely affected individuals. However, the pathophysiology of this disorder is not well understood. Host microbiome interactions that affect both innate and adaptive immune homeostasis appear to be a central factor in this disease, with recent observations suggesting that the composition and activities of the microbiota in acne is perturbed. Staphylococcus epidermidis and Cutibacterium acnes (C. acnes; formerly Propionibacterium acnes) are two major inhabitants of the skin that are thought to contribute to the disease but are also known to promote health by inhibiting the growth and invasion of pathogens. Because C. acnes is ubiquitous in sebaceous rich skin, it is typically labeled as the etiological agent of acne yet it fails to fulfill all of Koch's postulates. The outdated model of acne progression proposes that increased sebum production promotes over-proliferation of C. acnes in a plugged hair follicle, thereby driving inflammation. In contrast, growing evidence indicates that C. acnes is equally abundant in both unaffected and acne affected follicles. Moreover, recent advances in metagenomic sequencing of the acne microbiome have revealed a diverse population structure distinct from healthy individuals, uncovering new lineage-specific virulence determinants. In this article, we review recent developments in the interactions of skin microbes with host immunity, discussing the contribution of dysbiosis to the immunobiology of acne and newly emerging skin microbiome-based therapeutics to treat acne. PMID- 30285863 TI - Projecting the end of the Zika virus epidemic in Latin America: a modelling analysis. AB - BACKGROUND: Zika virus (ZIKV) emerged in Latin America and the Caribbean (LAC) region in 2013, with serious implications for population health in the region. In 2016, the World Health Organization declared the ZIKV outbreak a Public Health Emergency of International Concern following a cluster of associated neurological disorders and neonatal malformations. In 2017, Zika cases declined, but future incidence in LAC remains uncertain due to gaps in our understanding, considerable variation in surveillance and the lack of a comprehensive collation of data from affected countries. METHODS: Our analysis combines information on confirmed and suspected Zika cases across LAC countries and a spatio-temporal dynamic transmission model for ZIKV infection to determine key transmission parameters and projected incidence in 90 major cities within 35 countries. Seasonality was determined by spatio-temporal estimates of Aedes aegypti vectorial capacity. We used country and state-level data from 2015 to mid-2017 to infer key model parameters, country-specific disease reporting rates, and the 2018 projected incidence. A 10-fold cross-validation approach was used to validate parameter estimates to out-of-sample epidemic trajectories. RESULTS: There was limited transmission in 2015, but in 2016 and 2017 there was sufficient opportunity for wide-spread ZIKV transmission in most cities, resulting in the depletion of susceptible individuals. We predict that the highest number of cases in 2018 would present within some Brazilian States (Sao Paulo and Rio de Janeiro), Colombia and French Guiana, but the estimated number of cases were no more than a few hundred. Model estimates of the timing of the peak in incidence were correlated (p < 0.05) with the reported peak in incidence. The reporting rate varied across countries, with lower reporting rates for those with only confirmed cases compared to those who reported both confirmed and suspected cases. CONCLUSIONS: The findings suggest that the ZIKV epidemic is by and large over within LAC, with incidence projected to be low in most cities in 2018. Local low levels of transmission are probable, but the estimated rate of infection suggests that most cities have a population with high levels of herd immunity. PMID- 30285866 TI - The HEART score in predicting major adverse cardiac events in patients presenting to the emergency department with possible acute coronary syndrome: protocol for a systematic review and meta-analysis. AB - BACKGROUND: Acute coronary syndrome (ACS) is a common, sometimes difficult to diagnose spectrum of diseases occurring after abrupt reduction in blood flow through a coronary artery. Given the diagnostic challenge, it is sensible for emergency physicians to have an approach to prognosticate patients with possible ACS. Multiple prediction models have been developed to help identify patients at increased risk of adverse outcomes. The HEART score is the first model to be derived, validated, and undergo clinical impact studies in emergency department (ED) patients with possible ACS. OBJECTIVE: To develop a protocol for a prognostic systematic review of the literature evaluating the HEART score as a predictor of major adverse cardiac events (MACE) in patients presenting to the ED with possible ACS. METHODS/DESIGN: This protocol is reported according to the PRISMA-P statement and is registered on PROSPERO. All methodological tools to be used are endorsed by the Cochrane Prognosis Methods Group. Pre-defined eligibility criteria are provided. Multiple strategies will be used to identify potentially relevant studies. Studies will be selected and data extracted using standardised forms based on the CHARMS checklist. The QUIPS tool will be used to assess the risk of bias within individual studies. Outcome measures will include prevalence, risk ratio, and absolute risk reduction for MACE within 6 weeks of ED evaluation, comparing HEART scores 0-3 versus 4-10. HEART score prognostic performance will be evaluated with the concordance (C) statistic (model discrimination), observed to expected events ratio (model calibration), and a decision curve analysis. Reporting biases and methodological, clinical, and statistical heterogeneity will be scrutinised. Unless deemed inappropriate, a meta-analysis and pre-defined subgroup and sensitivity analyses will be performed. Overall judgements about evidence quality and strength of recommendations will be summarised using the GRADE approach. DISCUSSION: This review will identify, select, and appraise studies evaluating the prognostic performance of the HEART score, producing results of interest to emergency physicians. These results may encourage shared clinical decision-making in the ED by facilitating risk communication with patients and health care providers. SYSTEMATIC REVIEW REGISTRATION: PROSPERO 2017 CRD42017084400 . PMID- 30285865 TI - PRC2 targeting is a therapeutic strategy for EZ score defined high-risk multiple myeloma patients and overcome resistance to IMiDs. AB - BACKGROUND: Multiple myeloma (MM) is a malignant plasma cell disease with a poor survival, characterized by the accumulation of myeloma cells (MMCs) within the bone marrow. Epigenetic modifications in MM are associated not only with cancer development and progression, but also with drug resistance. METHODS: We identified a significant upregulation of the polycomb repressive complex 2 (PRC2) core genes in MM cells in association with proliferation. We used EPZ-6438, a specific small molecule inhibitor of EZH2 methyltransferase activity, to evaluate its effects on MM cells phenotype and gene expression prolile. RESULTS: PRC2 targeting results in growth inhibition due to cell cycle arrest and apoptosis together with polycomb, DNA methylation, TP53, and RB1 target genes induction. Resistance to EZH2 inhibitor is mediated by DNA methylation of PRC2 target genes. We also demonstrate a synergistic effect of EPZ-6438 and lenalidomide, a conventional drug used for MM treatment, activating B cell transcription factors and tumor suppressor gene expression in concert with MYC repression. We establish a gene expression-based EZ score allowing to identify poor prognosis patients that could benefit from EZH2 inhibitor treatment. CONCLUSIONS: These data suggest that PRC2 targeting in association with IMiDs could have a therapeutic interest in MM patients characterized by high EZ score values, reactivating B cell transcription factors, and tumor suppressor genes. PMID- 30285867 TI - Characteristics of lung cancer among patients with idiopathic pulmonary fibrosis and interstitial lung disease - analysis of institutional and population data. AB - BACKGROUND: Lung Cancer is occasionally observed in patients with Idiopathic Pulmonary Fibrosis (IPF). We sought to describe the epidemiologic and clinical characteristics of lung cancer for patients with IPF and other interstitial lung disease (ILD) using institutional and statewide data registries. METHODS: We conducted a retrospective analysis of IPF and non-IPF ILD patients from the ILD center registry, to compare with lung cancer registries at the University of Pittsburgh as well as with population data of lung cancer obtained from Pennsylvania Department of Health between 2000 and 2015. RESULTS: Among 1108 IPF patients, 31 patients were identified with IPF and lung cancer. The age-adjusted standard incidence ratio of lung cancer was 3.34 (with IPF) and 2.3 (with non-IPF ILD) (between-group Hazard ratio = 1.4, p = 0.3). Lung cancer worsened the mortality of IPF (p < 0.001). Lung cancer with IPF had higher mortality compared to lung cancer in non-IPF ILD (Hazard ratio = 6.2, p = 0.001). Lung cancer among IPF was characterized by a predilection for lower lobes (63% vs. 26% in non-IPF lung cancer, p < 0.001) and by squamous cell histology (41% vs. 29%, p = 0.07). Increased incidence of lung cancer was observed among single lung transplant (SLT) recipients for IPF (13 out of 97, 13.4%), with increased mortality compared to SLT for IPF without lung cancer (p = 0.028) during observational period. CONCLUSIONS: Lung cancer is approximately 3.34 times more frequently diagnosed in IPF patients compared to general population, and associated with worse prognosis compared with IPF without lung cancer, with squamous cell carcinoma and lower lobe predilection. The causality between non-smoking IPF patients and lung cancer is to be determined. PMID- 30285868 TI - A nomogram-based immunoprofile predicts overall survival for previously untreated patients with esophageal squamous cell carcinoma after esophagectomy. AB - BACKGROUND: Immunoscore, as a prognostic tool defined to quantify in situ immune cell infiltrates, appears to be superior to the TNM staging system. In esophageal squamous cell carcinoma (ESCC), no immunoscore has been established; however, in situ tumor immunology is recognized as highly important. Our study aimed to construct a comprehensive immunoprofile for ESCC. METHODS: The infiltration of four immune cell types (CD8+/CD4+/Foxp3+/CD33+ cells), the expression of both inhibitory (PD-1/PD-L1/Tim-3/LAG-3) and stimulatory checkpoints (OX-40/ICOS), and IDO1 were evaluated by IHC staining and multi-color immunofluorescence in two independent cohorts (95 patients in the primary cohort and 55 patients in the validation cohort). The association with patients' overall survival was analyzed by the Kaplan-Meier method and the Cox model. Nomogram-based immunoprofile was established using the independent prognostic variables. To determine its predictive accuracy and discriminatory capacity, the C-index and calibration curve were calculated. RESULTS: Significant correlation of PD-L1 expression in tumor cells with PD-1+ T cell infiltration was found (P = 0.035), indicating the activation of the inhibitory PD-1/PD-L1 pathway in ESCC cases. More PD-L1+ ICs, Tim-3+ ICs and LAG-3+ ICs were found in the CD8-rich tumor microenvironment, which is in accordance with the feedback nature of immune system. After adjustment by TNM stage, four immune variables including the infiltration of CD8+/Foxp3+/CD33+ cells and the PD-L1 expression by tumor cells were selected to construct a prognostic nomogram. The calibration curves showed good accuracy of the nomogram for survival prediction. To overcome the complexity of applying a nomogram in a clinical setting, a simple immunoprofile was then established according to the points of each factor from the nomogram. Our immunoprofile model could separate same-stage patients into different risk subgroups, and showed superior accuracy for survival prediction than the TNM staging system based on the C-index calculation and ROC analysis. CONCLUSIONS: Our nomogram-based immunoprofile can provide more accurate prognosis prediction and is an important complement to the TNM staging system for operable ESCC patients. PMID- 30285870 TI - Lipolysis and antioxidant properties of cow and buffalo cheddar cheese in accelerated ripening. AB - BACKGROUND: Buffalo milk is the second largest source of milk on the globe, it is highly suitable for the preparation of mozzarella cheese, however, it is not suitable for the preparation of cheddar cheese due to high buffering capacity, low acid development, excessive syneresis, lower lipolysis that lead to lower sensory score. Accelerated ripening can enhance lipolysis and improve sensory characteristics of cheddar cheese. Lipolysis and antioxidant capacity of buffalo cheddar cheese in conventional ripening is not previously studied. Optimization of ripening conditions can lead to better utilization of buffalo milk in cheese industry. METHODS: Effect of accelerated ripening on lipolysis and antioxidant properties of cow and buffalo cheddar cheese were investigated. Cheddar cheese prepared from standardized (3.5% fat) cow and buffalo milk was subjected to conventional and accelerated ripening (4 degrees C and 12 degrees C) for a period of 120 days. Fatty acid profile, organic acids, free fatty acids, cholesterol, antioxidant activity and sensory characteristics were studied at 0, 40, 80 and 120 days of ripening. RESULTS: Fatty acid profile of cow and buffalo cheddar in conventional (120 days old) and accelerated ripening were different from each other (p < 0.05). Free fatty acids in 120 days old buffalo and control cheddar, in accelerated ripening were 0.55% and 0.62%. After accelerated ripening, cholesterol in buffalo and control cheddars were 16 and 72 mg/100 g. After accelerated ripening, concentrations of formic, pyruvic, lactic, acetic and citric acids in buffalo cheddar cheese were, 922, 136, 19,200, 468 and 2845 ppm. At the end of accelerated ripening (120 days), concentrations of formic, pyruvic, lactic, acetic and citric acids in cow cheddar cheese were 578, 95, 9600, 347 and 1015 ppm. Total antioxidant capacity of control cow and buffalo cheddar in accelerated ripening was 77.26 and 88.30%. Colour, flavour and texture score of rapid ripened 80 and 120 days old buffalo cheddar was not different from cow cheddar. CONCLUSIONS: Results of this investigations showed that flavour profile buffalo cheddar subjected to accelerate ripening was similar to cow cheddar cheese. Accelerated ripening can be used for better utilization of buffalo milk in cheddar cheese industry. PMID- 30285869 TI - Powered ankle-foot orthoses: the effects of the assistance on healthy and impaired users while walking. AB - In the last two decades, numerous powered ankle-foot orthoses have been developed. Despite similar designs and control strategies being shared by some of these devices, their performance in terms of achieving a comparable goal varies. It has been shown that the effect of powered ankle-foot orthoses on healthy users is altered by some factors of the testing protocol. This paper provides an overview of the effect of powered walking on healthy and weakened users. It identifies a set of key factors influencing the performance of powered ankle-foot orthoses, and it presents the effects of these factors on healthy subjects, highlighting the similarities and differences of the results obtained in different works. Furthermore, the outcomes of studies performed on elderly and impaired subjects walking with powered ankle-foot orthoses are compared, to outline the effects of powered walking on these users. This article shows that several factors mutually influence the performance of powered ankle-foot orthoses on their users and, for this reason, the determination of their effects on the user is not straightforward. One of the key factors is the adaptation of users to provided assistance. This factor is very important for the assessment of the effects of powered ankle-foot orthoses on users, however, it is not always reported by studies. Moreover, future works should report, together with the results, the list of influencing factors used in the protocol, to facilitate the comparison of the obtained results. This article also underlines the need for a standardized method to benchmark the actuators of powered ankle-foot orthoses, which would ease the comparison of results between the performed studies. In this paper, the lack of studies on elderly and impaired subjects is highlighted. The insufficiency of these studies makes it difficult to assess the effects of powered ankle-foot orthoses on these users.To summarize, this article provides a detailed overview of the work performed on powered ankle-foot orthoses, presenting and analyzing the results obtained, but also emphasizing topics on which more research is still required. PMID- 30285871 TI - Identification of two residues within the NS1 of H7N9 influenza A virus that critically affect the protein stability and function. AB - The emerging avian-origin H7N9 influenza A virus, which causes mild to lethal human respiratory disease, continues to circulate in China, posing a great threat to public health. Influenza NS1 protein plays a key role in counteracting host innate immune responses, allowing the virus to efficiently replicate in the host. In this study, we compared NS1 amino acid sequences of H7N9 influenza A virus with those of other strains, and determined NS1 protein variability within the H7N9 virus and then evaluated the impact of amino acid substitutions on ability of the NS1 proteins to inhibit host innate immunity. Interestingly, the amino acid residue S212 was identified to have a profound effect on the primary function of NS1, since S212P substitution disabled H7N9 NS1 in suppressing the host RIG-I-dependent interferon response, as well as the ability to promote the virus replication. In addition, we identified another amino acid residue, I178, serving as a key site to keep NS1 protein high steady-state levels. When the isoleucine was replaced by valine at 178 site (I178V mutation), NS1 of H7N9 underwent rapid degradation through proteasome pathway. Furthermore, we observed that P212S and V178I mutation in NS1 of PR8 virus enhanced virulence and promoted the virus replication in vivo. Together, these results indicate that residues I178 and S212 within H7N9 NS1 protein are critical for stability and functioning of the NS1 protein respectively, and may contribute to the enhanced pathogenicity of H7N9 influenza virus. PMID- 30285872 TI - Serious adverse events and fatal adverse events associated with nivolumab treatment in cancer patients : Nivolumab-related serious/fatal adverse events. AB - BACKGROUND: Nivolumab, an immune checkpoint inhibitor, has revolutionized the treatment of many cancers. Due to its novel mechanisms of action, nivolumab induces a distinct profile of adverse events. Currently, the incidence and risk of developing serious adverse events (SAEs) or fatal adverse events (FAEs) following nivolumab administration are unclear. METHODS: We conducted a systematic search for phase 2 and phase 3 nivolumab trials in PubMed and Embase from inception to June 2018. Data on SAEs/FAEs were extracted from each study and pooled to calculate the overall incidence and odds ratios (ORs). RESULTS: A total of 21 trials with 6173 cancer patients were included in this study. The overall incidence of SAEs and FAEs with nivolumab were 11.2% (95% CI, 8.7-13.8%) and 0.3% (95% CI, 0.1-0.5%), respectively. The incidence of SAEs varied significantly with cancer type and clinical phase, but no evidence of heterogeneity was found for FAEs. Compared with conventional treatment, the administration of nivolumab did not increase the risk of SAEs (OR, 0.69; 95% CI, 0.34-1.40; p = 0.29) or FAEs (OR, 0.61; 95% CI, 0.27-1.39; p = 0.24). SAEs occurred in the major organ systems in a dispersed manner, with the most common toxicities appearing in the respiratory (21.4%), gastrointestinal (7.7%), and hepatic systems (6.6%). The most common cause of SAEs/FAEs was pneumonitis. CONCLUSIONS: Although nivolumab is a relatively safe antitumor agent, nononcologists should be advised of the potential adverse events. Additionally, future studies are needed to identify patients at high risk of SAEs/FAEs to aid in the development of optimal monitoring strategies and the exploration of treatments to decrease the risks. PMID- 30285873 TI - Vitamin B12 deficiency-induced pseudothrombotic microangiopathy without macrocytosis presenting with acute renal failure: a case report. AB - BACKGROUND: Vitamin B12 deficiency-induced thrombotic microangiopathy, known as pseudothrombotic microangiopathy, is a rare condition which resembles the clinical features of thrombotic thrombocytopenic purpura but requires a markedly different treatment. Most cases of vitamin B12 deficiency have only mild hematological findings, but in approximately 10% of patients life-threatening conditions have been reported. CASE PRESENTATION: We report a case of a 46-year old Moroccan man presenting with severe hemolytic anemia, thrombocytopenia, and renal failure in absence of macrocytosis, thus mimicking a genuine thrombotic thrombocytopenic purpura. Rapid improvement of renal function observed with only hydration and transfusions of packed red blood cells and the presence of pancytopenia suggested a bone marrow deficiency associated to a hemolytic component of unclear origin. Detection of low levels of vitamin B12 and rapid restitutio ad integrum with its replacement supported the diagnosis of pseudothrombotic thrombocytopenic purpura caused by vitamin B12 deficiency. CONCLUSIONS: Diagnosis of pseudothrombotic thrombocytopenic purpura caused by vitamin B12 deficiency might be difficult. Awareness of clinicians toward this differential diagnosis might spare patients from unnecessary therapeutic plasma exchange that is burdened by morbidity and mortality. PMID- 30285874 TI - Impact of ZBTB7A hypomethylation and expression patterns on treatment response to hydroxyurea. AB - BACKGROUND: We aimed to clarify the emerging epigenetic landscape in a group of genes classified as "modifier genes" of the beta-type globin genes (HBB cluster), known to operate in trans to accomplish the two natural developmental switches in globin expression, from embryonic to fetal during the first trimester of conception and from fetal to adult around the time of birth. The epigenetic alterations were determined in adult sickle cell anemia (SCA) homozygotes and SCA/beta-thalassemia compound heterozygotes of Greek origin, who are under hydroxyurea (HU) treatment. Patients were distinguished in HU responders and HU non-responders (those not benefited from the HU) and both, and in vivo and in vitro approaches were implemented. RESULTS: We examined the CpG islands' DNA methylation profile of BCL11A, KLF1, MYB, MAP3K5, SIN3A, ZBTB7A, and GATA2, along with gamma-globin and LRF/ZBTB7A expression levels. In vitro treatment of hematopoietic stem cells (HSCs) with HU induced a significant DNA hypomethylation pattern in ZBTB7A (p*, 0.04) and GATA2 (p*, 0.03) CpGs exclusively in the HU non responders. Also, this group of patients exhibited significantly elevated baseline methylation patterns in ZBTB7A, before the HU treatment, compared to HU responders (p*, 0.019) and to control group of healthy individuals (p*, 0.021), which resembles a potential epigenetic barrier for the gamma-globin expression. gamma-Globin expression in vitro matched with detected HbF levels during patients' monitoring tests (in vivo) under HU treatment, implying a good reproducibility of the in vitro HU epigenetic effect. LRF/ZBTB7A expression was elevated only in the HU non-responders under the influence of HU. CONCLUSIONS: This is one of the very first pharmacoepigenomic studies indicating that the hypomethylation of ZBTB7A during HU treatment enhances the LRF expression, which by its turn suppresses the HbF resumption in the HU non-responders. Its role as an epigenetic regulator of hemoglobin switching is also supported by the wide distribution of ZBTB7A-binding sites within the 5' CpG sequences of all studied human HBB cluster "modifier genes." Also, the baseline methylation level of selective CpGs in ZBTB7A and GATA2 could be an indicator of the negative HU response among the beta-type hemoglobinopathy patients. PMID- 30285875 TI - Improving preventive and health promotion care for children. AB - The emerging science in early childhood development challenges past paradigms of health care. There is consideration within the profession of paediatrics, and health care more broadly, of how to make systems of care more responsive to the developmental and social needs of young children and their families. Some countries have physician-centric models, either general physicians or paediatricians, while others rely on nurses. There is increasing recognition that the goal of any model should be parent-professional partnership that puts families at the center, elicits and responds to family needs, anticipates and supports families with developmental transitions, and fits within a seamless system of services and supports. PMID- 30285876 TI - Survival of patients with chronic heart failure in the community: a systematic review and meta-analysis protocol. AB - BACKGROUND: Heart failure (HF) is a common condition affecting more than 10% of those over 70 years of age. Reliable estimates of survival following a diagnosis of HF are important to guide management and facilitate advanced care planning. Most existing research has focused on survival rates for patients admitted to hospital with acute HF. However, the majority of patients with HF are diagnosed in the outpatient setting and can have periods of sustained symptom stability in the chronic phase of their illness. There has not been a systematic review of the literature to determine the prognosis of patients with chronic HF in the community. METHODS: We will undertake a comprehensive search of the following databases: CINAHL, Database of Abstracts of Reviews of Effects, Embase, MEDLINE and the Clinical Trials Register ( clinicaltrials.gov ). Two reviewers will independently complete screening, data extraction and quality appraisal with the option of input from a third reviewer to arbitrate. We will include data from observational or database studies conducted in either community or outpatient settings. Studies of acute HF or specific subgroups of patients will be excluded. There is no restriction by geographical setting, publication language or study date. We will complete QUIPS and GRADE assessments to systematically appraise the quality of evidence within and between studies. Where possible, we will seek to pool results to conduct a meta-analysis and undertake relevant subgroup analysis including by study setting, participant age and study decade. The primary outcome will be survival time from diagnosis. The secondary outcomes will be HF-related hospital admissions, symptom burden and measures of morbidity. DISCUSSION: This systematic review will provide up to date evidence on the current survival rates and prognostic indicators for patients with chronic HF. We will put this into historical perspective, comparing outcomes across time to help understand the impact of advances in evidence-based treatment on average survival. This information is important in facilitating informed decision-making for patients and health professionals as well as highlighting areas to focus resources and improve public health planning.

AB - BACKGROUND: The efficacy of cholesterol lowering agents, specifically statins, in slowing the rate of decline of cognitive function in Alzheimer's disease (AD) patients is not yet fully understood. Our team's previously published paper showed that patients who used statins demonstrated no increase in cognitive decline in mild cognitive impairment when compared with nonusers. Further, AD patients on statins demonstrated a slight decreasing trend in cognitive decline. The purpose of this study is therefore to investigate the association between stain use in AD confirmed by clinical diagnosis and autopsy and the pathological burden (plaques, tangles, Braak stage). The hypothesis leading this investigation is that prolonged statin use associates with lower AD pathology at autopsy. METHODS: We queried the National Alzheimer's Coordinating Center (NACC) database for autopsy-confirmed AD cases. Of the Uniform Data Set (UDS) participants who are deceased, 16,163 were diagnosed with dementia at their last UDS visit prior to death, and autopsy data are available for 3945 patients. These patients were then stratified into two groups based upon statin use. The two groups were then analyzed for their pathological AD burden, including total plaques, total tangles, age at death, age of onset, and Braak stage. RESULTS: NACC data were available for 1816 subjects with clinically and pathologically confirmed AD; 1558 were not on statins and 258 were on statins. No significant differences in age at death, age at onset, Braak stages, mean total tau, and mean total amyloid were found between the two subject groups. When statin use was analyzed by apolipoprotein E (ApoE) genotype carrier statins, the presence of ApoE4 did not influence the effects (or lack thereof) of statin use. CONCLUSIONS: Prolonged statin use in pathologically confirmed AD dementia does not appear to influence the amount of burden of plaques and tangles or Braak stage. These observations were not altered by the presence of absence of ApoE4. PMID- 30285878 TI - Circular RNA BCRC-3 suppresses bladder cancer proliferation through miR-182 5p/p27 axis. AB - BACKGROUND: Circular RNAs (circRNAs) are a new member of noncoding RNAs (ncRNAs) that have recently been described as key regulators of gene expression. Our previous study had identified the negative correlation between circHIPK3 and bladder cancer grade, invasion, as well as lymph node metastasis. However, the roles of circRNAs in cellular proliferation in bladder cancer remain largely unknown. METHODS: We had analyzed circRNA high-throughout sequencing from human tissues and determined bladder cancer related circRNA-3 (BCRC-3, GenBank: KU921434.1) as a new candidate circRNA derived from PSMD1 gene. The expression levels of circRNAs, mRNAs and miRNAs in human tissues and cells were detected by quantitative real-time PCR (qRT-PCR). The effects of BCRC-3 on cancer cells were explored by transfecting with plasmids in vitro and in vivo. RNA pull down assay, luciferase reporter assay and fluorescence in situ hybridization were applied to verify the interaction between BCRC-3 and microRNAs. Anticancer effects of methyl jasmonate (MJ) were measured by flow cytometry assay, western blot and qRT-PCR. RESULTS: BCRC-3 was lowly expressed in bladder cancer tissues and cell lines. Proliferation of BC cells was suppressed by ectopic expression of BCRC-3 in vitro and in vivo. Mechanistically, overexpression of BCRC-3 induced the expression of cyclin-dependent kinase inhibitor 1B (p27). Importantly, BCRC-3 could directly interact with miR-182-5p, and subsequently act as a miRNA sponge to promote the miR-182-5p-targeted 3'UTR activity of p27. Furthermore, MJ significantly increased the expression of BCRC-3, resulting in an obvious up-regulation of p27. CONCLUSIONS: BCRC-3 functions as a tumor inhibitor to suppress BC cell proliferation through miR-182-5p/p27 axis, which would be a novel target for BC therapy. PMID- 30285880 TI - Prognostic value of microRNAs in head and neck cancers: a systematic review and meta-analysis protocol. AB - BACKGROUND: Head and neck cancers form a significant share of all cancer incidences worldwide. Though treatment modalities exist, post-treatment recurrence and survival rates in recurrent patients continue to be high. MiRNAs offer an effective method of estimating the probability of recurrence and survival of HNC patients, thereby allowing for effective treatment and better survival rates. METHODS: The systematic review protocol was prepared according to the Preferred Reporting Items for Systematic Review and Meta-Analyses Protocols (PRISMA-P) 2015 statement. Relevant studies will be identified by a rigorous search of multiple bibliographical databases, including MEDLINE, Scopus, PubMed, Web of Science, Embase and Science Direct, without any language restrictions (up to June 2018). The primary screening will be performed by a review team via analysis of titles and abstracts of published articles. Final selection of articles will be achieved by two independent reviewers, based on predefined selection criteria. Data will be extracted from eligible studies using a pre piloted data extraction form. Statistical analysis will be performed on the basis of available data, extracted from eligible studies. Meta-analysis will be performed, and a forest plot will be generated, to determine pooled hazard ratios (HR) and 95% confidence interval (CI) using CMA. A fixed or random-effects model of meta-analysis will be used depending upon the between-study heterogeneity; publication bias will be determined by the Egger's bias indicator test. A narrative synthesis will be undertaken where statistical data is found to be insufficient. DISCUSSION: There is a lack of highly sensitive and specific biomarkers for estimating the HNC patients' prognostic outcomes, particularly in post-treatment conditions. This systematic review will identify and validate specific miRNA as prognostic biomarkers by utilising a collection of previously published data on miRNA expression and survival. Highlighting these prognostic specific miRNAs will have major clinical implications by allowing for better overall treatment strategies and patient survival estimates, by offering clinicians a method of quantitatively analysing prognosis via miRNA expression.

PMID- 30285879 TI - Robotic renal cyst decortication with calyceal diverticulectomy in a toddler - technical practicalities: a case report. AB - BACKGROUND: Incidence of simultaneous renal cyst with calyceal diverticula in contralateral kidney is rare in children. A minimally invasive procedure in different sittings is often recommended. CASE PRESENTATION: A Chinese 15-month old boy presented to the Urology department of a tertiary care center with right flank pain. He was subjected to magnetic resonance urography and was diagnosed as having right renal cyst and contralateral calyceal diverticula. He underwent robotic cyst decortication and calyceal diverticulectomy using da Vinci robot. His postoperative period was uneventful. He was discharged on fifth postoperative day. Histopathology was consistent with simple renal cyst. CONCLUSIONS: Robotic combined cyst decortication and contralateral diverticulectomy is feasible in selected small children. However, it demands adequate technical skill and experience. PMID- 30285881 TI - Surgical peritoneal stress creates a pro-metastatic niche promoting resistance to apoptosis via IL-8. AB - BACKGROUND: The mainstay of treatment of advanced ovarian cancer (AOC) involves chemotherapy, and debulking surgery. However, despite optimal surgical procedure and adjuvant chemotherapy, 60% of patients with AOC will relapse within 5 years. Most recurrences occur in the peritoneal cavity, suggesting the existence of occult sanctuaries where ovarian cancer cells (OCC) are protected. In murine models, surgical stress favors tumor growth; however, it has never been established that surgery may affect OCC sensitivity to subsequent chemotherapy. In this study, we investigated how the surgical stress could affect the chemosensitivity of OCC. METHODS: To avoid bias due to tumor burden in peritoneal cavity and duration of surgery, we used peritoneal biopsies from patients without a malignancy at precise time points. During laparotomies, peritoneal biopsies at the incision site were performed at the time of incision (H0 sample) and 1 h after initiation of surgery (H1 sample). We evaluated the chemoresistance to Taxol (0-20 uM) induced by H0 or H1 incubation (24 h) in two ovarian cancer cell lines OVCAR3 and SKOV3 and a primary cancer cell lines derived in our laboratory. RESULTS: Our results indicate that stressed peritoneum overexpressed cytokines, resulting in OCC increased resistance to therapy. Among these cytokines, IL8 was responsible for the resistance to apoptosis through the AKT pathway activation. Chemoresistance in OCC persists through the establishment of an autocrine IL8 loop. Finally, in a cohort of 32 patients, we showed an impact of IL8 tumoral overexpression on chemosensitivity and survival outcomes with a significant association to earlier recurrence. CONCLUSIONS: Our study demonstrated that precision surgery where targeted treatment would be used in combination with surgery is essential to obtain better tumor control. PMID- 30285882 TI - Concentrations of nicotine, nitrosamines, and humectants in legal and illegal cigarettes in Mexico. AB - BACKGROUND: Article 10 of the World Health Organization Framework Convention on Tobacco Control states the need for industry disclosure of tobacco contents and emissions. Currently, the profiles of key tobacco compounds in legal and illegal cigarettes are largely unknown. We aimed to analyze and compare concentrations of nicotine, nitrosamines, and humectants in legal and illegal cigarettes collected from a representative sample of smokers. METHODS: Participants of the International Tobacco Control cohort provided a cigarette pack of the brand they smoked during the 2014 wave. Brands were classified as legal or illegal according to the Mexican legislation. Nicotine, nitrosamines, glycerol, propylene glycol, and pH were quantified in seven randomly selected packs of each brand. All analyses were done blinded to legality status. Average concentrations per brand and global averages for legal and illegal brands were calculated. Comparisons between legal and illegal brands were conducted using t tests. RESULTS: Participants provided 76 different brands, from which 6.8% were illegal. Legal brands had higher nicotine (15.05 +/- 1.89 mg/g vs 12.09 +/- 2.69 mg/g; p < 0001), glycerol (12.98 +/- 8.03 vs 2.93 +/- 1.96 mg/g; p < 0.001), and N nitrosanatabine (NAT) (1087.5 +/- 127.0 vs 738.5 +/- 338 ng/g; p = 0.006) concentrations compared to illegal brands. For all other compounds, legal and illegal brands had similar concentrations. CONCLUSION: Compared to illegal cigarettes, legal brands seem to have higher concentrations of nicotine, NAT, and glycerol. Efforts must be made to implement and enforce Article 10 of the Framework Convention on Tobacco Control to provide transparent information to consumers, regulators, and policy-makers; and to limit cigarette engineering from the tobacco industry. PMID- 30285883 TI - Breast cancer survival predicted by TP53 mutation status differs markedly depending on treatment. AB - BACKGROUND: Previous studies on the role of TP53 mutation in breast cancer treatment response and survival are contradictory and inconclusive, limited by the use of different endpoints to determine clinical significance and by small sample sizes that prohibit stratification by treatment. METHODS: We utilized large datasets to examine overall survival according to TP53 mutation status in patients across multiple clinical features and treatments. RESULTS: Confirming other studies, we found that in all patients and in hormone therapy-treated patients, TP53 wild-type status conferred superior 5-year overall survival, but survival curves crossed at 10 or more years. In contrast, further stratification within the large dataset revealed that in patients receiving chemotherapy and no hormone therapy, wild-type TP53 status conferred remarkably poor overall survival. This previously unrecognized inferior survival is consistent with p53 inducing arrest/senescence instead of apoptosis. Addition of hormone therapy to chemotherapy improved survival notably in patients with TP53 wild-type tumors, but not mutant, suggesting hormone therapy could eradicate arrested/senescent cells. Testing this, we found that estrogen receptor-positive, TP53 wild-type breast cancer cells that were made senescent by doxorubicin treatment were sensitive to tamoxifen. CONCLUSIONS: The poor survival of chemotherapy-treated patients with TP53 wild-type tumors may be improved by strategies to eliminate senescent cells, including the addition of hormone therapy when appropriate. PMID- 30285884 TI - A retrospective dosimetry study of intensity-modulated radiotherapy for nasopharyngeal carcinoma: radiation-induced brainstem injury and dose-volume analysis. AB - BACKGROUND: Radiation therapy is the standard radical treatment for nasopharyngeal carcinoma (NPC) but also causes transient as well as long-term complications. Patients who develop severe radiation-induced brainstem injuries have a poor prognosis due to the lack of effective medical therapies. However, the relationship between brainstem injury and radiation volume dose is unknown. In this study, we found that radiation-induced brainstem injury was significantly associated with brainstem dose per unit volume. METHODS: A retrospective analysis was performed on a consecutive cohort of 327 patients with NPC receiving IMRT from May 2005 to December 2014. Dose-volume data and long-term outcome were analyzed. RESULTS: The median follow-up duration was 56 months (range, 3-141 months), and six with T4 and two with T3 patients had radiation-induced brainstem injuries. The 3-year and 5-year incidences were 2.2% and 2.8%, respectively. The latency period of brainstem injury ranged from 9 to 58 months, with a median period of 21 months. The Cox regression analysis showed that brainstem radiation toxicity was associated with the T4 stage, D2% of gross tumor volume of nasopharyngeal primary lesions and their direct extensions (GTVnx), Dmax (the maximum point dose), D1%, D0.1cc (the top dose delivered to a 0.1-ml volume), and D1cc (the top dose delivered to a 1-ml volume) of the brainstem (p < 0.05). Receiver operating characteristic (ROC) curves showed that GTVnx D2% and the Dmax, D1%, D0.1cc, and D1cc of the brainstem were significant predictors of brainstem injury. The area under the ROC curve for these five parameters was 0.724, 0.813, 0.818, 0.818, and 0.798, respectively (p < 0.001), and the cutoff points 77.26 Gy, 67.85 Gy, 60.13 Gy, 60.75 Gy, and 54.58 Gy, respectively, were deemed as the radiation dose limit. CONCLUSIONS: Radiotherapy-induced brainstem injury was uncommon in patients with NPC who received definitive IMRT. Multiple dose-volume data may be the dose tolerance of radiation-induced brainstem injury. PMID- 30285885 TI - MiR-425 expression profiling in acute myeloid leukemia might guide the treatment choice between allogeneic transplantation and chemotherapy. AB - BACKGROUND: Acute myeloid leukemia (AML) is a highly heterogeneous disease. MicroRNAs function as important biomarkers in the clinical prognosis of AML. METHODS: This study identified miR-425 as a prognostic factor in AML by screening the TCGA dataset. A total of 162 patients with AML were enrolled for the study and divided into chemotherapy and allogeneic hematopoietic stem cell transplantation (allo-HSCT) groups. RESULTS: In the chemotherapy group, patients with high miR-425 expression had significantly longer overall survival (OS) and event-free survival (EFS) compared with patients with low miR-425 expression. In multivariate analyses, high miR-425 expression remained independently predictive of a better OS (HR = 0.502, P = 0.005) and EFS (HR = 0.432, P = 0.001) compared with patients with low miR-425 expression. Then, all patients were divided into two groups based on the median expression levels of miR-425. Notably, the patients undergoing allo-HSCT had significantly better OS (HR = 0.302, P < 0.0001) and EFS (HR = 0.379, P < 0.0001) compared with patients treated with chemotherapy in the low-miR-425-expression group. Mechanistically, high miR-425 expression levels were associated with a profile significantly involved in regulating cellular metabolism. Among these genes, MAP3K5, SMAD2, and SMAD5 were predicted targets of miR-425. CONCLUSIONS: The expression of miR-425 may be useful in identifying patients in need of strategies to select the optimal therapy between chemotherapy and allo-HSCT treatment regimens. Patients with low miR-425 expression may consider early allo-HSCT. PMID- 30285886 TI - Primary pulmonary meningioma mimicking lung metastatic tumor: a case report. AB - BACKGROUND: Primary pulmonary meningioma (PPM) is an extremely rare benign tumor. Previous reports indicated that CT features of PPM are single, solid, well demarcated, homogeneous mass. In this study, we report a case of PPM with atypical CT features. CASE PRESENTATION: A 65-year-old female presents to clinic with 1-week acute upper respiratory tract infection. Her chest CT scan revealed a 25-29 mm, round-like, heterogeneous lobulated solitary pulmonary nodule in the right lower lobe. Based on the microscopic features and a wide range of immunohistochemical examinations including vimentine, progesterone receptor (PR), CD34 and S100, the mass was diagnosed as PPM after surgery. CONCLUSION: PPM is a rare disease, CT features of PPM could be heterogeneous and lobulated. Expression of vimentine, PR, CD34 and S100 helps to diagnosis of PPM. PMID- 30285887 TI - Assessment of left ventricular systolic and diastolic abnormalities in patients with hypertrophic cardiomyopathy using real-time three-dimensional echocardiography and two-dimensional speckle tracking imaging. AB - BACKGROUND: Conventional echocardiography is not sensitive enough to assess left ventricular (LV) dysfunction in hypertrophic cardiomyopathy (HCM) patients. This research attempts to find a new ultrasonic technology to better assess LV diastolic function, systolic function, and myocardial longitudinal and circumferential systolic strain of segments with different thicknesses in HCM patients. METHODS: This study included 50 patients with HCM and 40 healthy subjects as controls. The peak early and late mitral annulus diastolic velocities at six loci (Ea' and Aa', respectively) and the Ea'/Aa' ratio were measured using real-time tri-plane echocardiography and quantitative tissue velocity imaging (RT 3PE-QTVI). The mean value of Ea' at six loci (Em') was obtained for the calculation of E/Em' ratio. The LV end-diastolic volume (LVEDV), LV end-systolic volume (LVESV), LV stroke volume (LVSV), and LV ejection fraction (LVEF) were measured using real-time three-dimensional echocardiography (RT-3DE). LV myocardial longitudinal peak systolic strain (LPSS) and circumferential peak systolic strain (CPSS) in the apical-middle-basal segments (LPSS-api, LPSS-mid, LPSS-bas; CPSS-api, CPSS-mid, and CPSS-bas, respectively) were obtained using a software for two-dimensional speckle tracking imaging (2D-STI). According to the different segmental thicknesses (STs) in each HCM patient, the values (LPSS and CPSS) of all the myocardial segments were categorized into three groups and the respective averages were computed. RESULTS: The Ea', Aa', and, Ea'/Aa' ratio in HCM patients were lower than those in the controls (all p < 0.001), while the E/Em' ratio in HCM patients was higher than that in the controls (p < 0.001). The LVEDV, LVSV, and LVEF were significantly lower in HCM patients than in controls (all p < 0.001). In HCM patients, the LPSS-api, LPSS-mid, LPSS-bas, CPSS-api, CPSS-mid, and CPSS-bas and the LPSS and CPSS of LV segments with different thicknesses were all significantly reduced (all p < 0.001). CONCLUSIONS: In HCM patients, myocardial dysfunction was widespread not only in the obviously hypertrophic segments but also in the non-hypertrophic segments; the LV systolic and diastolic functions were damaged, even with a normal LVEF. LV diastolic dysfunction, systolic dysfunction, and myocardial deformation impairment in HCM patients can be sensitively revealed by RT-3PE-QTVI, RT-3DE, and 2D-STI. PMID- 30285888 TI - Using concept mapping to develop a human rights based indicator framework to assess country efforts to strengthen rehabilitation provision and policy: the Rehabilitation System Diagnosis and Dialogue framework (RESYST). AB - BACKGROUND: Rehabilitation is crucial for the realization of the right to health and a proper concern of global health. Yet, reliable information to guide rehabilitation service planning is unavailable in many countries in part due to the lack of appropriate indicators. To ensure universal health coverage and meet the central imperative of "leaving no one behind" countries must be able to assess key aspects of rehabilitation policy and provision and monitor how they have discharged their human rights responsibilities towards those most disadvantaged, including people with disability. This article describes the process of developing an expert guided indicator framework to assess governments' efforts and progress in strengthening rehabilitation in line with the Convention on the Rights of Persons with Disabilities. METHODS: A systems methodology - concept mapping - was used to capture, aggregate and confirm the knowledge of diverse stakeholders on measures thought to be useful for monitoring the implementation of the Convention with respect to health related rehabilitation. Fifty-six individuals generated a list of 107 indicators through online brainstorming which were subsequently sorted by 37 experts from the original panel into non overlapping categories. Forty-one participants rated the indicators for importance and feasibility. Multivariate statistical techniques where used to explore patterns and themes in the data and create the indicators' organizing framework which was verified and interpreted by a select number of participants. RESULTS: A concept map of 11 clusters of indicators emerged from the analysis grouped into three broader themes: Governance and Leadership (3 clusters); Service Delivery, Financing and Oversight (6 clusters); and Human Resources (2 clusters). The indicator framework was comprehensive and well aligned with the Convention. On average, there was a moderately positive correlation between importance and feasibility of the indicators (r = .58) with experts prioritizing the indicators contained in the clusters of the Governance and Leadership domain. Two of the most important indicators arose from the Service Delivery, Financing and Oversight domain and reflect the need to monitor unmet needs and barriers in access to rehabilitation. In total, 59 indicators achieved above average score for importance and comprised the two-tiered priority set of indicators. CONCLUSION: Concept mapping was successful in generating a shared model that enables a system's view of the most critical legal, policy and programmatic factors that must be addressed when assessing country efforts to reform, upscale and improve rehabilitation services. The Rehabilitation Systems Diagnosis and Dialogue framework provides a data driven basis for the development of standardized data collection tools to facilitate comparative analysis of rehabilitation systems. Despite agreement on the importance and feasibility of 59 indicators, further research is needed to appraise the applicability and utility of the indicators and secure a realistic assessment of rehabilitation systems. PMID- 30285889 TI - Novel 4D-MRI of tumor infiltrating vasculature: characterizing tumor and vessel volume motion for selective boost volume definition in pancreatic radiotherapy. AB - BACKGROUND: Pancreatic ductal adenocarcinoma has dismal prognosis. Most patients receive radiation therapy (RT), which is complicated by respiration induced organ motion in upper abdomen. The purpose of this study is to report our early clinical experience in a novel self-gated k-space sorted four-dimensional magnetic resonance imaging (4D-MRI) with slab-selective (SS) excitation to highlight tumor infiltrating blood vessels for pancreatic RT. METHODS: Ten consecutive patients with borderline resectable or locally advanced pancreatic cancer were recruited to the study. Non-contrast 4D-MRI with and without slab selective excitation and 4D-CT with delay contrast were performed on all patients. Vessel-tissue CNR were calculated for aorta and critical vessels (superior mesenteric artery or superior mesenteric vein) encompassed by tumor. Respiratory motion trajectories for tumor, as well as involved vessels were analyzed on SS-4D-MRI. Intra-class cross correlation (ICC) between tumor volume and involved vessels were calculated. RESULTS: Among all 4D imaging modalities evaluated, SS-4D-MRI sampling trajectory results in images with highest vessel tissue CNR comparing to non-slab-selective 4D-MRI and 4D-CT for all patients studied. Average (+/-standard deviation) CNR for involved vessels are 13.1 +/- 8.4 and 3.2 +/- 2.7 for SS-4D-MRI and 4D-CT, respectively. The ICC factors comparing tumor and involved vessels motion trajectories are 0.93 +/- 0.10, 0.65 +/- 0.31 and 0.77 +/- 0.23 for superior-inferior, anterior-posterior and medial lateral directions respectively. CONCLUSIONS: A novel 4D-MRI sequence based on 3D radial sampling and slab-selective excitation has been assessed for pancreatic cancer patients. The non-contrast 4D-MRI images showed significantly better contrast to noise ratio for the vessels that limit tumor resectability compared to 4D-CT with delayed contrast. The sequence has great potential in accurately defining both the tumor and boost volume margins for pancreas RT with simultaneous integrated boost. PMID- 30285890 TI - Attenuated bidirectional short-term synaptic plasticity in the dentate gyrus of Schnurri-2 knockout mice, a model of schizophrenia. AB - The dentate gyrus of the hippocampus has been implicated in the pathophysiological basis of neuropsychiatric disorders including schizophrenia. We have identified several mouse models of neuropsychiatric disorders with robust molecular and functional defects in the dentate gyrus. Among them, mice lacking Schnurri-2 (Shn2 or HIVEP2) have been proposed as a model of schizophrenia and intellectual disability. Shn2 knockout mice exhibit behavioral abnormalities resembling symptoms of schizophrenia and HIVEP2-related intellectual disability as well as marked functional alterations in the soma and output synapse of the dentate granule cells (GCs). Although robust abnormalities were also observed in the dendritic spine morphology in the GCs, their functional correlates remain unknown. In the present study, we performed electrophysiological analyses of synaptic transmission at the medial perforant path (MPP) input onto the GCs in Shn2 knockout mice. While the basal synaptic efficacy was preserved, short-term synaptic depression induced by paired-pulse or low-frequency stimulation was reduced in the mutant mice. High-frequency tetanic stimulation induced lasting synaptic potentiation in both wild-type and mutant mice. However, the decaying synaptic potentiation shortly after the tetanic stimulation was significantly reduced in the mutant mice. These results indicate that the Shn2 deficiency attenuates bidirectional short-term synaptic plasticity at the MPP-GC synapse, thereby rendering the synapse more static. Our finding further supports a possible role of the dentate gyrus dysfunction in pathophysiology of schizophrenia and may also provide important information in interpreting morphology changes of the brain synapses in neuropsychiatric disorders. PMID- 30285891 TI - Acupuncture for irritable bowel syndrome: study protocol for a multicenter randomized controlled trial. AB - BACKGROUND: Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder characterized by abdominal pain and change of bowel habit without organic disease. A global perspective given by the World Gastroenterology Organization (WGO) points out that IBS can impact the quality of an individual's daily life, cause socioeconomic problems and potentially impair the patient-physician relationship. It remains a problem to treat IBS due to the complicated pathophysiology. Acupuncture is an alternative therapy recommended for IBS. The aim of this study is to investigate the efficacy and safety of acupuncture therapy for patients with IBS. We also want to explore the correlation between IBS-gene subtypes and acupuncture effect. METHODS/DESIGN: A multicenter randomized controlled trial will be performed in seven hospitals. Six hundred participants will be stratified into two strata (IBS-C or IBS-D). Then, patients within each stratum will be divided into an experimental group and a control group randomly. The experimental group is treated with acupuncture while the control group is treated with Western medicine. All the patients will receive a 6 week treatment and a 3-month follow-up. The primary outcome is the IBS-Symptom Severity Score (IBS-SSS), the secondary outcome is the score of the IBS-Quality of Life (IBS-QoL).The correlation between IBS-gene subtypes and acupuncture effect will be detected based on polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Outcome measures (including primary and secondary outcome measures) are collected at baseline,1 week, 2 weeks, 4 weeks, and 6 weeks of the intervention, and 12 weeks after the intervention. DISCUSSION: This is a multicenter randomized controlled trial for IBS in China. It may clarify the efficacy of acupuncture as an alternative therapy for IBS. This is the first time ever that the potential mechanism of IBS based on genomics has been investigated. TRIAL REGISTRATION: Chinese Clinical Trials Register, ID: ChiCTR-IOR-15006259 . First registered on 14 April 2015. PMID- 30285892 TI - Suppression of lung cancer progression by isoliquiritigenin through its metabolite 2, 4, 2', 4'-Tetrahydroxychalcone. AB - BACKGROUND: Licorice is an herb extensively used for both culinary and medicinal purposes. Various constituents of licorice have been shown to exhibit anti tumorigenic effect in diverse cancer types. However, majority of these studies focus on the aspect of their growth-suppressive role. In this study, we systematically analyzed known licorice's constituents on the goal of identifying component(s) that can effectively suppress both cell migration and growth. METHODS: Effect of licorice's constituents on cell growth was evaluated by MTT assay while cell migration was assessed by both wound-healing and Transwell assays. Cytoskeleton reorganization and focal adhesion assembly were visualized by immunofluorescence staining with labeled phalloidin and anti-paxillin antibody. Activity of Src in cells was judged by western blot using phosphor Src416 antibody while Src kinase activity was measured using Promega Src kinase assay system. Anti-tumorigenic capabilities of isoliquiritigenin (ISL) and 2, 4, 2', 4'-Tetrahydroxychalcone (THC) were investigated using lung cancer xenograft model. RESULTS: Using a panel of lung cancer cell lines, ISL was identified as the only licorice's constituent capable of inhibiting both cell migration and growth. ISL-led inhibition in cell migration resulted from impaired cytoskeleton reorganization and focal adhesion assembly. Assessing the phosphorylation of 141 cytoskeleton dynamics-associated proteins revealed that ISL reduced the abundance of Tyr421-phosphorylation of cortactin, Tyr925- and Tyr861-phosphorylation of FAK, indicating the involvement of Src because these sites are known to be phosphorylated by Src. Enigmatically, ISL inhibited Src in cells while displayed no effect on Src activity in cell-free system. The discrepancy was explained by the observation that THC, one of the major ISL metabolite identified in lung cancer cells abrogated Src activity both in cells and cell-free system. Similar to ISL, THC deterred cell migration and abolished cytoskeleton reorganization/focal adhesion assembly. Furthermore, we showed both ISL and THC suppressed in vitro lung cancer cell invasion and in vivo tumor progression. CONCLUSION: Our study suggests that ISL inhibits lung cancer cell migration and tumorigenesis by interfering with Src through its metabolite THC. As licorice is safely used for culinary purposes, our study suggests that ISL or THC may be safely used as a Src inhibitor. PMID- 30285895 TI - Prevalence and associated factors of low birth weight in Axum town, Tigray, North Ethiopia. AB - OBJECTIVE: Weight at birth is a good indicator of the newborn's chances for survival, growth, long-term health and psychosocial development. Therefore, the aimed of this study is to assess the prevalence and associated factors of low birth weight in Axum town, Tigray, North Ethiopia. RESULT: The magnitude of low birth weight was 8.8%. Height of mother adjusted odds ratio (AOR) 4.607 (CI 1.34 15.8), gestational age AOR 4.7 (CI 1.08-20.44), anti-natal care (ANC) visit AOR 0.076 (CI 0.009-0.645), anemia during pregnancy AOR 14.5 (CI 3.821-55.6) and drinking alcohol AOR 6.4 (CI 1.235-33.94) were found to be significantly associated with low birth weight. Pre-conceptual counseling on nutrition, about the effect of short suture on birth outcome and personal maternal habit (drinking alcohol), effective treatment and prevention of anemia and awareness on the importance ANC follow up should be the target. PMID- 30285894 TI - Treatment of pustular psoriasis with anakinra: a statistical analysis plan for stage 1 of an adaptive two-staged randomised placebo-controlled trial. AB - BACKGROUND: Palmoplantar pustulosis (PPP) is a rare, chronic inflammatory skin disease. It is known to affect quality of life at a level comparable to that from major medical and psychiatric illness, yet current treatment options are remarkably limited. Recent evidence however suggests that interleukin-1 (IL-1) blockade with anakinra will deliver therapeutic benefit in PPP. METHODS: Anakinra for Pustular psoriasis: Response in a Controlled Trial (APRICOT) is a two-staged, adaptive, double-blind, randomised placebo-controlled trial which aims to test the hypothesis that IL-1 blockade with anakinra will deliver therapeutic benefit in PPP. During stage 1 a total of 24 patients will be randomised (1:1) to receive either placebo or anakinra. The two candidate primary outcomes are fresh pustule count (across palms and soles) and the Palmoplantar Pustulosis Area and Severity Index (PPPASI) score, recorded at baseline and at weeks 1, 4 and 8. Analysis at the end of stage 1 will compare treatment arms to ensure sufficient efficacy and safety in order to progress to stage 2. The primary outcome for stage 2 will also be identified following an assessment of the reliability and discriminative ability of fresh pustule count and PPPASI. The trial is powered to detect efficacy and will recruit an additional 40 patients in stage 2 (n = 64 in total). Analysis will follow the intention-to-treat principle and analyse patients as randomised. DISCUSSION: This manuscript describes the important features of the small population trial design for APRICOT and the pre-specified statistical analysis plan for stage 1. The statistical analysis plan has been developed prior to data extraction and in compliance with international guidelines. It will increase the transparency of the data analysis for the APRICOT trial. The findings of the trial will help to clarify the role of anakinra in the treatment of PPP.

AB - BACKGROUND: Functional magnetic resonance imaging may provide several quantitative indices strictly related to distinctive tissue signatures with radiobiological relevance, such as tissue cellular density and vascular perfusion. The role of Intravoxel Incoherent Motion Diffusion Weighted Imaging (IVIM-DWI) and Dynamic Contrast-Enhanced (DCE) MRI in detecting/predicting radiation-induced volumetric changes of parotids both during and shortly after (chemo)radiotherapy of oropharyngeal squamous cell carcinoma (SCC) was explored. METHODS: Patients with locally advanced oropharyngeal SCC were accrued within a prospective study offering both IVIM-DWI and DCE-MRI at baseline; IVIM-DWI was repeated at the 10th fraction of treatment. Apparent diffusion coefficient (ADC), tissue diffusion coefficient Dt, perfusion fraction f and perfusion-related diffusion coefficient D* were estimated both at baseline and during RT. Semi quantitative and quantitative parameters, including the transfer constant Ktrans, were calculated from DCE-MRI. Parotids were contoured on T2-weighted images at baseline, 10th fraction and 8th weeks after treatment end and the percent change of parotid volume between baseline/10th fr (?Vol10fr) and baseline/8th wk. (?Volpost) computed. Correlations among volumetric changes and patient-, treatment- and imaging-related features were investigated at univariate analysis (Spearman's Rho). RESULTS: Eighty parotids (40 patients) were analyzed. Percent changes were 18.2 +/- 10.7% and 31.3 +/- 15.8% for ?Vol10fr and ?Volpost, respectively. Among baseline characteristics, ?Vol10fr was correlated to body mass index, patient weight as well as the initial parotid volume. A weak correlation was present between parotid shrinkage after the first 2 weeks of treatment and dosimetric variables, while no association was found after radiotherapy. Percent changes of both ADC and Dt at the 10th fraction were also correlated to ?Vol10fr. Significant relationships were found between ?Volpost and baseline DCE-MRI parameters. CONCLUSIONS: Both IVIM-DWI and DCE-MRI can help to detect/predict early (during treatment) and shortly after treatment completion the parotid shrinkage. They may contribute to clarify the correlations between volumetric changes of parotid glands and patient-/treatment-related variables by assessing individual microcapillary perfusion and tissue diffusivity.

AB - OBJECTIVES: To develop successful mass-rearing programs of edible insects, knowledge of the feeds and their influence on nutritional content is critical. We assessed the influence of natural food plants (grass inflorescences) and their mixtures on fatty acid profiles of edible Ruspolia differens. We reared neonate nymphs to adult on six dietary treatments consisting of one, and mixtures of two, three, five, six and eight plants. RESULTS: The contents of saturated, monounsaturated and polyunsaturated fatty acids, omega-6/omega-3 ratio, and adult body weight did not differ among dietary treatments. However, the composition of fatty acids differed significantly among insects fed on six dietary treatments, but only for the rare fatty acids. Our results demonstrate that even if natural diets (grass inflorescences) do not strongly modify fatty acid contents or compositions of R. differens, when reared from neonate nymphs to adults, their n 6/n - 3 fatty acid ratio is generally low and thus good for a healthy human diet. PMID- 30285896 TI - Blocking CD248 molecules in perivascular stromal cells of patients with systemic sclerosis strongly inhibits their differentiation toward myofibroblasts and proliferation: a new potential target for antifibrotic therapy. AB - BACKGROUND: Fibrosis may be considered the hallmark of systemic sclerosis (SSc), the end stage triggered by different pathological events. Transforming growth factor-beta (TGF-beta) and platelet-derived growth factor BB (PDGF-BB) are profibrotic molecules modulating myofibroblast differentiation and proliferation, respectively. There is evidence linking CD248 with these two molecules, both highly expressed in patients with SSc, and suggesting that CD248 may be a therapeutic target for several diseases. The aim of this work was to evaluate the expression of CD248 in SSc skin and its ability to modulate SSc fibrotic process. METHODS: After ethical approval was obtained, skin biopsies were collected from 20 patients with SSc and 10 healthy control subjects (HC). CD248 expression was investigated in the skin, as well as in bone marrow mesenchymal stem cells (MSCs) treated with TGF-beta or PDGF-BB, by immunofluorescence, qRT-PCR, and Western blotting. Finally, in SSc-MSCs, the CD248 gene was silenced by siRNA. RESULTS: Increased expression of CD248 was found in endothelial cells and perivascular stromal cells of SSc skin. In SSc-MSCs, the levels of CD248 and alpha-smooth muscle actin expression were significantly higher than in HC-MSCs. In both SSc- and HC-MSCs, PDGF-BB induced increased expression of Ki-67 when compared with untreated cells but was unable to modulate CD248 levels. After CD248 silencing, both TGF-beta and PDGF-BB signaling were inhibited in SSc-MSCs. CONCLUSIONS: CD248 overexpression may play an important role in the fibrotic process by modulating the molecular target, leading to perivascular cells differentiation toward myofibroblasts and interfering with its expression, and thus might open a new therapeutic strategy to inhibit myofibroblast generation during SSc.

AB - OBJECTIVE: To assess factors associated treatment outcomes of acute post streptococcal glomerular nephritis among patients less than 18 years old in Mekelle City Public Hospitals. RESULTS: About 334 medical records c of children with acute post streptococcal glomerular nephritis were revised during the study period. Of these 244 (73.1%) had a positive outcome. acute post streptococcal glomerular nephritis was found to be statically significant associated with age < 5 years, duration of infection, the source of infection and length of stay in Hospital. PMID- 30285898 TI - Laboratory evaluation of the efficacy of lotilaner (CredelioTM) against Amblyomma cajennense (sensu lato) infestations of dogs. AB - BACKGROUND: The ixodid tick Amblyomma cajennense (sensu lato) complex, widespread throughout South and Central America, is also present in Mexico, Texas and Florida. As a vector of Rickettsia rickettsii, and potentially of other pathogens, infestations with A. cajennense present a substantial health risk to humans, dogs and other mammals. Oral administration of lotilaner flavored chewable tablets (CredelioTM, Elanco) to dogs was previously shown to rapidly provide killing activity of infesting ticks. This study investigated lotilaner's efficacy against A. cajennense (s.l.). METHODS: Twenty purpose-bred Beagles (10 male and 10 female) were ranked by Day -5 burdens of nymphal A. cajennense (s.l.) and randomized to either treatment with lotilaner or to a sham-treated control group. On Day 0, dogs were fed within approximately 30 min prior to oral lotilaner administration at as close as possible to 20 mg/kg, the minimum dose rate. For efficacy assessments, tick counts were completed 48 h post-treatment or 48 h after experimental challenge infestations with 200 nymphal A. cajennense (s.l.) on Days -7, -2, 7, 14, 21 and 28. RESULTS: Tick infestations in the control group dogs ranged from a low of 43 to 95, with the average infestation remaining above 25% at each assessment, thereby meeting the requirement for efficacy comparison with the treated group. Lotilaner efficacy was 100% within 48 h post-treatment, and at nine days post-treatment. Efficacy was greater than 99% at all subsequent assessments through Day 30. No treatment-related adverse events were observed. CONCLUSION: The results demonstrate that lotilaner, administered orally to dogs at a minimum dose of 20 mg/kg is well tolerated, provides rapid reduction of existing A. cajennense (s.l.) tick infestations, and provides sustained residual protection for at least 30 days against subsequent infestation by A. cajennense (s.l.). PMID- 30285900 TI - Swept source optical coherence tomography and optical coherence tomography angiography in pediatric enhanced S-cone syndrome: a case report. AB - BACKGROUND: Enhanced S-cone syndrome is an autosomal recessive retinal dystrophy related to a defect in a nuclear receptor gene (NR2E3) that leads to alteration in cells development from rod to S-cone. This retinal dystrophy may be associated with retinal schisis. The aim of this report is to describe structural optical coherence tomography and optical coherence tomography angiography features in a case of enhanced S-cone syndrome associated with macular schisis. CASE PRESENTATION: A Caucasian 13-year-old girl underwent measurement of best corrected visual acuity, ophthalmoscopic evaluation, and fundus autofluorescence examination. Photopic and scotopic electroretinography were carried out as well. Enhanced S-cone syndrome was suspected on the basis of clinical and electrophysiological findings. Structural optical coherence tomography and optical coherence tomography angiography allowed the further characterization of the associated macular schisis. Genetic analysis not only confirmed the diagnosis but increased the clinical novelty of this case report by showing two variations in the NR2E3 gene probably related to the phenotype: a missense variation c.1118T>C which leads to the substitution of leucine with proline in amino acid position 373, and c.349+5G>C, which involves a gene sequence near a splicing site. CONCLUSIONS: Swept source structural optical coherence tomography (B scans and "en face" images) and optical coherence tomography angiography allowed the observation of retinal structural details and the involvement of each retinal layer and capillary plexus in enhanced S-cone syndrome. Of interest, neither of the two NR2E3 gene variants found in this case report have been linked to any form of retinopathy. PMID- 30285901 TI - Improving research and policy interactions requires a better understanding of what works in different contexts. AB - There is keen interest in many jurisdictions in finding ways to improve the way that research evidence informs policy. One possible mechanism for this is to embed academics within government agencies either as advisers or full staff members. Our commentary argues that, in addition to considering the role of academics in government as proposed by Glied and colleagues, we need to understand better how research and policy interactions function across policy sectors. We believe more comparative research is needed to understand if and why academics from certain disciplines are more likely to be recruited to work in some policy sectors rather than others. We caution against treating government as monolithic by advocating the same model for collaborative interaction between academics and government. Lastly, we contend that contextualized research is needed to illuminate important drivers of research and policy interactions before we can recommend what is likely to be more and less effective in different policy sectors. PMID- 30285902 TI - Adoptive transfer of tumor-infiltrating lymphocytes in melanoma: a viable treatment option. AB - The treatment of metastatic melanoma patients with autologous tumor-infiltrating lymphocytes (TIL) shows robust, reproducible, clinical responses in clinical trials executed in several specialized centers over the world. Even in the era of targeted therapy and immune checkpoint inhibition, TIL therapy can be an additional and clinically relevant treatment line. This review provides an overview of the clinical experiences with TIL therapy thus far, including lymphodepleting regimens, the use of interleukin-2 (IL-2) and the associated toxicity. Characteristics of the TIL products and the antigen recognition pattern will be discussed, as well as the current and upcoming production strategies, including the selective expansion of specific fractions from the cell product. In addition, the future potential of TIL therapy in melanoma and other tumor types will be covered. PMID- 30285903 TI - Prediction of clinical outcomes in individuals with chronic low back pain: a protocol for a systematic review with meta-analysis. AB - BACKGROUND: Low back pain (LBP) is one of the most prevalent and recurrent conditions in the general population, with personal, professional, social and economic impact. However, there is a lack of consistent evidence about chronic low back pain (CLBP) prognosis, especially highlighting predictors that influence CLBP outcome. Existing systematic reviews are scarce, outdated and incomplete. The primary aim of this systematic review is to identify multivariable models and/or predictors associated with clinical outcomes in subjects with CLBP (namely pain intensity, disability, return to work, psychological well-being and quality of life). METHODS: We will systematically search Ovid MEDLINE (PubMed), Scopus and Web of Science databases for longitudinal studies, published until June 2017, including adults with CLBP (defined as persistent pain with >= 3 months duration), which studied the association between multivariable models and/or predictors with at least one of the selected clinical outcomes after >= 3 months of follow-up. Articles' screening and selection will be conducted by two reviewers, blindly and independently. Disagreements will be resolved by a third reviewer. Models' discriminative ability will be assessed using C-statistic. The link between multivariable models and predictors with the clinical outcome will be analysed through association measures. Qualitative and quantitative synthesis of the available evidence will be performed. Meta-analysis will be conducted to aggregate each type of measure. In the absence or in the presence of only slight to moderate of heterogeneity, we will use the fixed or random effects model, respectively. In case of moderate to severe heterogeneity, an attempt to explain variability in detail will be made through subgroups and sensitivity analyses. Subgroup analysis will be conducted according to clinical outcome, follow-up duration (<= 6 months versus > 6 months) and type of context (pain management clinics versus other therapeutic settings). DISCUSSION: We consider that it is urgent to highlight the available evidence about CLBP prognosis. This systematic review will help identify multivariable models and individual predictors that may enhance pain management success. One potential limitation will be the difficulty of aggregating quantitative measures from several prognostic models and predictors, with different clinical outcomes.

AB - BACKGROUND: Niemann-Pick disease type C (NP-C) is a neurodegenerative lysosomal lipid storage disease caused by autosomal recessive mutations in the NPC1 or NPC2 genes. The clinical presentation and evolution of NP-C and the effect of miglustat treatment are described in the largest cohort of patients with adolescent/adult-onset NP-C studied to date. METHODS: Observational study based on clinical chart data from adult patients with NP-C (> 18 year old) diagnosed in France between 1990 and 2015. Retrospective data from patients at diagnosis, onset of miglustat therapy (if applicable), and last follow up were analysed. RESULTS: In France, patients with an adolescent-adult neurological form constituted approximately 25% of all NP-C cases diagnosed during the study period. Forty-seven patients (46 with NP-C1 and one with NP-C2; 53% female) were included. Mean +/- SD (range) ages at neurological onset and diagnosis were 23.9 +/- 12.5 (8-56) years and 34 +/- 13.5 (15-65) years, respectively. At presentation, patients mainly had 1) impaired gait due to cerebellar ataxia and/or dystonia, 2) and/or cognitive/behavioural manifestations, 3) and/or psychotic signs. Initially, almost half of patients had only one of the above three neuro-psychiatric manifestations. Vertical supranuclear gaze palsy, usually occurring without patient complaint, was only detected on careful clinical examination and was recorded in most patients (93%) at the time of diagnosis, several years after neurological onset. Thirty-seven patients (79%) received miglustat, among whom seventeen (46%) continued beyond 2 years (at last follow up) to a maximum of 9.8 years. Eight patients (22%) discontinued treatment early due to side effects (n = 3) or perceived lack of efficacy (n = 5).Miglustat treatment duration correlated significantly with reduced neurological worsening (p < 0.001). Treatment for>=2 years was associated with improved patient survival (p = 0.029). Good responses to miglustat were associated with less severe neurological disability at the start of miglustat treatment (p = 0.02). CONCLUSION: The proportion of adolescent/adult-onset NP-C cases diagnosed in France increased 2.5-fold since 2009 compared with the 2000-2008 period due to improved awareness. Adolescent/adult-onset NP-C frequently presented initially with a non-specific isolated neuro-psychiatric manifestation (motor, cognitive or psychotic). Patients with less severe neurological disability responded better to miglustat therapy. PMID- 30285905 TI - Ibuprofen supports macrophage differentiation, T cell recruitment, and tumor suppression in a model of postpartum breast cancer. AB - BACKGROUND: Women diagnosed with breast cancer within 5 years postpartum (PPBC) have poorer prognosis than age matched nulliparous women, even after controlling for clinical variables known to impact disease outcomes. Through rodent modeling, the poor prognosis of PPBC has been attributed to physiologic mammary gland involution, which shapes a tumor promotional microenvironment through induction of wound-healing-like programs including myeloid cell recruitment. Previous studies utilizing immune compromised mice have shown that blocking prostaglandin synthesis reduces PPBC tumor progression in a tumor cell extrinsic manner. Given the reported roles of prostaglandins in myeloid and T cell biology, and the established importance of these immune cell populations in dictating tumor growth, we investigate the impact of involution on shaping the tumor immune milieu and its mitigation by ibuprofen in immune competent hosts. METHODS: In a syngeneic (D2A1) orthotopic Balb/c mouse model of PPBC, we characterized the impact of mammary gland involution and ibuprofen treatment on the immune milieu in tumors and draining lymph nodes utilizing flow cytometry, multiplex IHC, lipid mass spectroscopy and cytokine arrays. To further investigate the impact of ibuprofen on programming myeloid cell populations, we performed RNA-Seq on in vivo derived mammary myeloid cells from ibuprofen treated and untreated involution group mice. Further, we examined direct effects of ibuprofen through in vitro bone marrow derived myeloid cell cultures. RESULTS: Tumors implanted into the mammary involution microenvironment grow more rapidly and display a distinct immune milieu compared to tumors implanted into glands of nulliparous mice. This milieu is characterized by increased presence of immature monocytes and reduced numbers of T cells and is reversed upon ibuprofen treatment. Further, ibuprofen treatment enhances Th1 associated cytokines as well as promotes tumor border accumulation of T cells. Safety studies demonstrate ibuprofen does not impede gland involution, impact subsequent reproductive success, nor promote auto reactivity as detected through auto-antibody and naive T cell priming assays. CONCLUSIONS: Ibuprofen administration during the tumor promotional microenvironment of the involuting mammary gland reduces overall tumor growth and enhances anti-tumor immune characteristics while avoiding adverse autoimmune reactions. In sum, these studies implicate beneficial prophylactic use of ibuprofen during the pro-tumorigenic window of mammary gland involution. PMID- 30285907 TI - Non-adherence to anti-tuberculosis treatment, reasons and associated factors among TB patients attending at Gondar town health centers, Northwest Ethiopia. AB - OBJECTIVE: The aim of this study was to assess the prevalence of non-adherence to anti-tuberculosis treatment, reasons and associated factors among TB patients attending at Gondar town health centers. RESULT: A total of 314 participants were included with the response rate of 97.5%. The mean age of participants was 35.94 (SD +/- 13.83) years. The overall rate of non-adherence to anti-TB treatment was 21.2% (95% CI 17.2, 26.1). Continuation phase of treatment (AOR = 2.27, 95% CI (1.54, 5.94)), presence of more than one co-morbidity (AOR = 6.22; 95% CI (2.21, 17.48)), poor knowledge about TB and anti-TB therapy (AOR = 4.11; 95% CI 1.57, 10.75), poor patient-provider relationship (AOR = 4.60, 95% CI 1.63, 12.97), and alcohol intake (AOR = 5.03; 95% CI 1.54, 16.40) were significantly associated with non-adherence. Forgetting 40 (23.1%), Being busy with other work 35 (20.2%), and being out of home/town 24 (13.9%) were the major reasons of participants for interruption of taking anti-TB medications. PMID- 30285906 TI - Spatial distribution and populations at risk of A. lumbricoides and T. trichiura co-infections and infection intensity classes: an ecological study. AB - BACKGROUND: Soil-transmitted helminth (STH) infections are highly prevalent in the Philippines. Mapping the prevalence and high-intensity of STH co-infections can help guide targeted intervention programmes to reduce morbidity, especially among vulnerable school-aged children. In this study, we aimed to predict the spatial distribution of the prevalence of Ascaris lumbricoides and Trichuris trichiura co-infection and infection intensity classes in the Philippines to identify populations most in need of interventions. METHODS: Data on STH infections from 29,919 individuals during the nationwide parasitological survey in 2005 to 2007 were included in the analysis. To geographically predict the prevalence of A. lumbricoides and T. trichiura co-infections and infection intensity classes, Bayesian multinomial geostatistical models were built including age, sex, environmental variables and a geostatistical random effect. The number of individuals co-infected and belonging to each of the infection intensity classes in 2017 was forecast by combining our predictive prevalence maps with population density maps. RESULTS: Our models showed that school-aged children (5-19 years) are most at risk of A. lumbricoides and T. trichiura co infections and of moderate/high infection intensity compared to other age groups. We identified target provinces where the likelihood of STH-associated morbidity was highest: Luzon (Bulacan, Benguet, Cavite, Sorsogon, Metropolitan Manila, Pampanga and Rizal), the Visayas (Cebu, Iloilo, Leyte and Negros Occidental), and in Mindanao (Agusan Del Norte, Davao Del Sur, Davao Oriental, Lanao Del Sur, Maguindanao, Misamis Oriental, Sulu and Zamboanga Del Sur). Luzon had the highest estimated number of school-aged children with A. lumbricoides and T. trichiura co infections (estimated total 89,400), followed by the Visayas (38,300) and Mindanao (20,200). CONCLUSIONS: Our study provided epidemiological evidence to highlight national priority areas for controlling co-infections and high intensity infections in the Philippines. Our maps could assist more geographically targeted interventions to reduce the risk of STH-associated morbidity in the Philippines.

PMID- 30285908 TI - A fragile but critical link: a commentary on the importance of government-academy relationships. AB - Interactions between government and academia can be an important support to effective policy and they can also ground researchers' methods and perspectives more strongly in the realities of policy-making and politics, leading to more relevant research. If properly developed, these interactions can lead to relationships between government and academia that re-enforce evidence-informed policy and useful research. However, strong relationships require repeated interactions and strong personal connections, something that can be supported through careers that cross academia and government. Academic and public service polices that value these kinds of careers can help build strong relationships. PMID- 30285910 TI - Eubacterium maltosivorans sp. nov., a novel human intestinal acetogenic and butyrogenic bacterium with a versatile metabolism. AB - A novel anaerobic, non-spore-forming bacterium was isolated from a faecal sample of a healthy adult. The isolate, designated strain YIT, was cultured in a basal liquid medium under a gas phase of H2/CO2 supplemented with yeast extract (0.1 g l-1). Cells of strain YIT were short rods (0.4-0.7*2.0-2.5 um), appearing singly or in pairs, and stained Gram-positive. Catalase activity and gelatin hydrolysis were positive while oxidase activity, indole formation, urease activity and aesculin hydrolysis were negative. Growth was observed within a temperature range of 20-45 degrees C (optimum, 35-37 degrees C), and a pH range of 5.0-8.0 (optimum pH 7.0-7.5). Doubling time was 2.3 h when grown with glucose at pH 7.2 and 37 degrees C. Besides acetogenic growth, the isolate was able to ferment a large range of monomeric sugars with acetate and butyrate as the main end products. Strain YIT did not show respiratory growth with sulfate, sulfite, thiosulfate or nitrate as electron acceptors. The major cellular fatty acids of the isolate were C16 : 0 and C18 : 0. The genomic DNA G+C content was 47.8 mol%. Strain YIT is affiliated to the genus Eubacterium, sharing highest levels of 16S rRNA gene similarity with Eubacterium limosum ATCC 8486T (97.3 %), Eubacterium callanderi DSM 3662T (97.5 %), Eubacterium aggregans DSM 12183T (94.4 %) and Eubacterium barkeri DSM 1223T (94.8 %). Considering its physiological and phylogenetic characteristics, strain YIT represents a novel species within the genus Eubacterium, for which the name Eubacterium maltosivorans sp. nov. is proposed. The type strain is YIT (=DSM 105863T=JCM 32297T). PMID- 30285912 TI - Vidian Nerve Schwannoma: A Rare Skull-Base Neoplasm Presenting with Ocular Manifestations: A Case Report and Literature Review. AB - INTRODUCTION: Vidian nerve schwannomas are exceedingly rare, with only 7 cases reported since 2006. Patients presenting with ocular symptoms have been reported in only 1 case. CASE PRESENTATION: A 54-year-old woman presented with a 3-month history of right periorbital pressure, third cranial nerve palsy, and visual field defect. Imaging results showed a right sphenoid skull-base mass with obliteration of the vidian canal that extended into the pterygopalatine fossa. The patient underwent an extended endoscopic resection with pterygopalatine fossa dissection. Pathologic findings demonstrated a schwannoma. DISCUSSION: A literature review showed that this is the second reported case of a vidian nerve schwannoma presenting with ocular symptoms and that endoscopic resections are becoming the standard of care. Practitioners should be aware that vidian nerve schwannomas can present as a skull-base mass with predominantly ocular symptoms, including vision loss, secondary to mass effect. Consideration should be given to this entity in the setting of typical radiographic and histopathologic characteristics. Endoscopic approaches to resection are safe and have low morbidity. PMID- 30285911 TI - Desertimonas flava gen. nov., sp. nov. isolated from a desert soil, and proposal of Ilumatobacteraceae fam. nov. AB - A non-motile, coccobacilli-shaped and yellow-coloured bacterium, designated strain SYSU D60003T, was isolated from a desert soil sample. Cells were Gram stain-positive, catalase-negative and oxidase-positive. The whole cell hydrolysates contained ll-diaminopimelic acid as the diagnostic amino acid. The major fatty acids were C16 : 0, summed feature 3 (C16 : 1omega7c and/or C16 : 1omega6c) and iso-C16 : 0. The respiratory menaquinones were MK-9(H8), MK-9(H4) and MK-9(H6). The DNA G+C content was determined to be 70.2 % (genome). The polar lipids detected were diphosphatidylglycerol, an unidentified glycolipid and seven unidentified polar lipids. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SYSU D60003T belonged to the order Acidimicrobiales (class Acidimicrobiia), but formed a clade closely linked to members of the genus Ilumatobacter. Data from a polyphasic taxonomy study suggested that the isolate represents a novel species of a novel genus in the order Acidimicrobiales, for which the name Desertimonas flava gen. nov., sp. nov. is proposed. The type strain of the proposed new taxon is SYSU D60003T (=KCTC 39917T=NBRC 112924T). Additionally, the new taxon along with the genus Ilumatobater (family unassigned) were distinctly separated from the related families Acidimicrobiaceae, Iamiaceae and 'Microtrichaceae' in the phylogenetic trees, besides presenting a unique 16S rRNA gene signature nucleotides. Therefore, we propose a new family Ilumatobacteraceae fam. nov. within the order Acidimicrobiales to accommodate members of these two genera. PMID- 30285913 TI - Sex-Based Differences in Symptom Perception and Care-Seeking Behavior in Acute Stroke. AB - CONTEXT: Lack of early stroke recognition and delays in seeking emergency care by persons experiencing a stroke severely limit acute treatment options. Sparse and sometimes conflicting evidence suggests sex differences in care-seeking behaviors in stroke, stroke knowledge, perceptions of stroke symptoms, and the importance of physical location at the time of stroke and of having a witnessed stroke. OBJECTIVE: To explore specific sex-based differences in stroke presentation and associated care-seeking behaviors. DESIGN: Descriptive study based on a convenience sample of 60 patients with stroke admitted to an academic medical center in Northern California. MAIN OUTCOME MEASURES: Impact of the patient's sex on 1) time to presentation (early [<= 4.5 hours] vs late [> 4.5 hours]); 2) perception of symptoms and clinical signs; 3) stroke knowledge and decision making; 4) physical location at the time of stroke; and 5) bystander presence and assistance with decision making. RESULTS: There was a discrepancy between how patients perceive symptoms and their medical findings on physical examination. Although most patients had at least one sign or symptom associated with nationally used stroke recognition acronyms, both sexes delayed care because they did not perceive their symptoms as urgent. Early-presenting men were more likely to have a higher stroke severity score at admission, receive alteplase, arrive by Emergency Medical Services, and have a witnessed stroke. Both early- and late presenting women reported more nonfocal symptoms than did men. CONCLUSION: This study suggests that there are sex-based differences in symptom perception and care-seeking behavior in acute ischemic stroke. PMID- 30285914 TI - Perceptions and Experience of Patients, Staff, and Clinicians with Social Needs Assessment. AB - CONTEXT: Assessment of social needs is expanding at Kaiser Permanente (KP), but little is known about how members and clinicians experience the incorporation of social needs into health care. OBJECTIVE: To assess how KP members and clinicians experience social needs assessments incorporated into care. DESIGN: Qualitative and descriptive analysis of data from member and clinician focus groups, interviews, and surveys among 68 members and family caregivers who had participated in social needs assessment programs and 90 clinicians and staff in the KP Colorado, Georgia, Northern California, Northwest, and Southern California Regions. MAIN OUTCOME MEASURES: Members' and clinicians' perceptions and experiences of social needs assessment. RESULTS: Members and clinicians understood the impact of social needs on health and why a health care system representative would ask about food, housing, transportation, and other social needs. Members and clinicians supported social needs assessment at KP and agreed that KP should help address identified social needs. However, both groups emphasized the importance of assessments yielding actionable information. Members were also concerned about how the information would be used and by whom. CONCLUSION: Our findings support the continuing assessment of social needs at KP and identify issues that require attention as it expands. Assessment should not outpace organizational capacity to connect members with resources. Careful attention to communications is required because members may be uncertain or concerned about the purpose of the assessment and the dissemination of sensitive information. Messaging should assure members about data use and dissemination and what they can expect after screening. PMID- 30285915 TI - "Do You Really Need This Appointment?" PMID- 30285916 TI - Effect of an Electronic Alert on Targeted HIV Testing Among High-Risk Populations. AB - CONTEXT: Screening for HIV infection in medical settings remains suboptimal. OBJECTIVE: To examine the real-world effectiveness of an electronic clinician alert on the same-day HIV testing rate and early diagnosis in high-risk populations. DESIGN: We identified Kaiser Permanente Southern California Health Plan members aged 14 years or older who received tests for sexually transmitted infections. MAIN OUTCOME MEASURES: Encounter-based same-day HIV testing rate, positive test result rate, and CD4+ cell count and HIV viral load at diagnosis. RESULTS: We identified 1,800,948 patients who made 2,326,701 health care encounters eligible for HIV testing before implementation (January 1, 2008 - June 30, 2012) and 1,362,479 eligible encounters after implementation (January 1, 2013 - June 30, 2015). The same-day HIV testing rate increased from 36.7% to 44.1% (standardized mean difference = 0.15, significant difference). The alert was associated with a moderate difference and statistically significant increase in the HIV testing rate (adjusted odds ratio = 1.17, 95% confidence interval = 1.16 1.18). The positive test result rate increased from 0.02% to 0.04% (p < 0.001). During the postimplementation period, fewer HIV-infected patients had a CD4+ cell count below 200 and/or an HIV viral load of 10,000 copies/mL or higher at diagnosis. CONCLUSION: Implementation of a targeted electronic alert embedded in the electronic medical record improved same-day HIV screening rate and positive test result rates among patients receiving tests for sexually transmitted infections in a large health organization. This intervention has potential for facilitating frequent screening and early identification of HIV infection in high risk populations. PMID- 30285917 TI - Cognitive Behavioral Therapy with Heart Rate Variability Biofeedback for Adults with Persistent Noncombat-Related Posttraumatic Stress Disorder. AB - OBJECTIVE: To test the effectiveness of a mental health therapy designed to reduce noncombat-related persistent posttraumatic stress disorder (PTSD) symptoms in 30 adult outpatients with a diagnosis of PTSD. The individual treatment offered modules to address PTSD nightmare distress, dissociation, general core skills, alterations in arousal and reactivity, avoidance, intrusion, and negative alternations in cognitions and mood. The therapeutic approach centered on cognitive behavioral therapy and heart rate variability biofeedback. METHODS: The study had 2 components: The quality improvement project that performed the treatment within a standard care environment, and a retrospective medical chart review process that analyzed the results. The Clinician-Administered PTSD Scale for the Diagnostic and Statistical Manual, Fifth Edition, was used to confirm the initial PTSD diagnosis and was the primary measure used to monitor change in the diagnosis following treatment. RESULTS: None of the patients who completed the PTSD treatment met criteria for a PTSD diagnosis in the posttreatment assessment. A 1-sample test of proportions, with a 95% confidence interval and a significance level of p < 0.05, showed p = 0.0008, and that the proportion of patients who would not have PTSD if the study was repeated would be 86.77% to 100.00%. The treatment dropout rate was 13% (4 patients). CONCLUSION: The study findings suggest that this intervention is an effective treatment for helping adult patients, including those with a history of childhood abuse, remit their PTSD diagnosis.

AB - Using a patient story, this narrative demonstrates why health care organizations, specifically primary care clinics, should strive to identify and to address social needs. This story demonstrates how Kaiser Permanente Washington, by using community resource specialists, has empowered primary care clinics to address social needs in a health care setting to improve patient care and experience. PMID- 30285920 TI - Different Harm and Mortality in Critically Ill Medical vs Surgical Patients: Retrospective Analysis of Variation in Adverse Events in Different Intensive Care Units. AB - BACKGROUND: Institutional harm reduction campaigns are essential in improving safe practice in critical care. Our institution embarked on an aggressive project to measure harm. We hypothesized that critically ill surgical patients were at increased risk of harm compared with medical intensive care patients. METHODS: Three years of administrative data for patients with at least 1 Intensive Care Unit day at an urban tertiary care center were assembled. Data were accessed from the Henry Ford Health System No Harm Campaign in Detroit, MI. Harm was defined as any unintended physical injury resulting from medical care. Patients were deemed surgical if they had at least 1 procedure in the operating room. Univariate analysis was used to compare surgical patients with nonsurgical. Logistic regression was used for risk adjustment in predicting harm and death. RESULTS: The study included 19,844 patients, of whom 7483 (37.7%) were surgical. The overall mortality was 7.8% (n = 1554). More surgical patients experienced harm than did nonsurgical patients (2923 [39.1%] vs 2798 [22.6%], odds ratio [OR] = 2.2, p < 0.001). Surgical patients were less likely to die (6.2% vs 8.8%, p < 0.001). Surgical patients were more likely to experience harm (OR = 2.1) but had lower mortalities (OR = 0.45) vs other harmed patients (OR = 3.8; all p < 0.001). CONCLUSION: Most harm in surgically critically ill patients is procedure related. Preliminary data show that harm is associated with death, yet both surgical and African American patients experience more harm with a lower mortality rate. PMID- 30285921 TI - Aortic root replacement with cryopreserved homograft for infective endocarditis in the modern North American opioid epidemic. AB - OBJECTIVE: To study mid-term survival in patients with infective endocarditis as a result of IV drug use undergoing aortic root replacement with cryopreserved aortic homograft. METHODS: Patients undergoing aortic root homograft replacement from 2011-2017 were studied retrospectively. Aortic root replacement was performed using a modified Bentall technique. Primary outcomes included both short-term and mid-term survival. Secondary outcomes included immediate postoperative complications. RESULTS: A total of 138 patients underwent cryopreserved homograft replacement of the aortic root for aortic root abscesses. Eighty-five patients (61.6%) underwent reoperative sternotomy, and 12 patients (8.7%) underwent second or third reoperative sternotomy. Sixty-seven (48.5%) patients had severe aortic insufficiency preoperatively. Operative mortality was 12.3% (17 patients). Five patients (3.6%) sustained a permanent stroke. Twenty one patients (15.2%) required dialysis for renal failure, and 21 patients (15.2%) had complete heart block necessitating a permanent pacemaker. Estimated 5-year mortality for the cohort was 43%. CONCLUSIONS: Cryopreserved homograft replacement is a safe and desirable option for high-risk patients with infective endocarditis and aortic root abscess. Homograft accommodation for a widely debrided aortic annular bed provides a reasonable surgical strategy for patients needing aortic root replacement with annular abscess. PMID- 30285922 TI - [Relevance of histopathological diagnosis in the treatment of brainstem lesions in adults]. AB - Brainstem tumors are uncommon beyond childhood. Controversies arise regarding the need of histological diagnosis in this eloquent area of the brain, weighting the benefits of a reliable diagnosis against the disadvantages of invasive procedures. There are scant publications about the surgical management of brainstem tumors in adults, all of them involving small retrospective cohorts. We are reporting our experience with the aim of contributing to the decision making process. Out of a series of 13 patients, 10 were approached surgically. According to Guillamo's classification the lesions were: focal (n:7), diffuse infiltrative (n:1), tectal (n:1), and exophytic (n:1). According to the Karnofsky Performance Status scale, the neurological status was = 70 in 6 cases and < 70 in 7. Histopathology was confirmed in all 10 treated cases and the samples were obtained by a direct microsurgical approach or by stereotactic biopsy. Histopathological findings were: pilocytic astrocytoma (n:1), low grade glioma (n:1), glioblastoma (n:1), cellular haemangioblastoma (n:1), subependimoma (n:1), pseudotumoral lesions (n:4; 3 cavernomas, 1 inflammatory pseudotumor), and disgerminoma (n:1). As a broad variety of pathologies could be found in this brain localization, an accurate histopathological definition can not only determine the adequate therapy, but also avoid the disastrous consequences of empiric treatments. PMID- 30285923 TI - [Susceptibility of Streptococcus pyogenes isolated from invasive infections to trimethoprim-sulfamethoxazole]. AB - It is erroneously believed that group A streptococci (GAS) are universally resistant to trimethoprim-sulfamethoxazole (TMS). This is mainly because media commonly used for in vitro determination of susceptibility to antibiotics contain thymidine, a nucleoside that antagonizes the antibiotic effect of TMS. The objective of this work was to determine EGA sensitivity to TMS in the presence and absence of thymidine. To this aim, 95 GAS isolates obtained from clinical tissues with i nvasive infections were analyzed. Susceptibility tests were performed by diffusion with TMS discs in Mueller Hinton agar supplemented either with 5% sheep blood or with 5% lysed equine blood (MH-LEB). Lysed equine blood contains thymidine phosphorylase, which degrades this nucleoside. Epsilometry (Etest) was used as gold standard. Quality controls with Enterococcus faecalis strain ATCC 29212 were satisfactory with both media. A 100% sensitivity to TMS was found in MH-SEL whereas 6 isolates (6.3%) resulted resistant in MH-SC; only one of them was found to have intermediate susceptibility by Etest (MIC > 1.5/28 upsilong/ml). The genetic determinants most frequently associated to TMS resistant EGA were not found in this isolate. Probably, if more accurate GAS specific cut-off points were established for diffusion, the correlation with dilution methods or with the Etest could be improved, even employing MH-SB. PMID- 30285924 TI - Epidemiological dynamic modeling of human papillomavirus-related diseases to assess vaccination strategies in Argentina. AB - Our objective was to develop and test a dynamic simulation model of human papillomavirus (HPV)-related diseases to assess rational vaccination strategies in Argentina. A dynamic stochastic transmission model for hetero- and homosexual transmission of HPV oncogenic and low-risk oncogenic types among females and males was developed. The model included HPV transmission and vaccination, the natural history of HPV-related diseases, disease outcomes, and cervical cancer screening. Considering all cervical cancers, covered or not by the current quadrivalent vaccine, the existing coverage rate would lead to 60% reduction in the global incidence of cervical cancer at 25 years, and to 79% at 50 years. Isolated current female vaccination without a screening program would need around 100 years to eliminate cervical cancer from the local population. Current coverage rate would lead to 59% reduction of vulvar cancer, 76% of vaginal cancer, 85% of anal cancer, and 87% of oropharyngeal cancer, estimated over a 25 year time prospect. Female HPV vaccination within the context of current cervical cancer screening should reach a minimum long-term mean coverage of 60% of girls, receiving at least a two-dose vaccine schedule, to significantly reduce or virtually eliminate cervical cancer at 50 years. Including vaccination to boys to improve herd immunity did not influence the incidence of cervical cancer over time, as long as female coverage did not fall below 50%. Regarding vulvar, vaginal, anal, penile, and some oropharyngeal cancers, current girls-only based vaccination could virtually eliminate these cancer types after 35-40 years, both in women and men. PMID- 30285925 TI - Cut-off values of immunological tests to identify patients at high risk of severe lupus nephritis. AB - Cut-off values for anti-dsDNA, anti-nucleosome and anti-C1q antibodies tests and for complementmediated hemolytic activity (CH50) were explored to identify patients with high risk of developing severe lupus nephritis (LN). Forty-one patients with confirmed systemic lupus erythematosus (SLE) were identified; their levels for the three antibodies and complement had been measured on a same serum sample. These patients were classified based on the presence of renal involvem ent; sixteen had active proliferative LN. With the cut-off values accepted in the laboratory for SLE diagnosis (anti-dsDNA > 100 UI/ml, anti-nucleosome > 50 U/ml or CH50 < 190 UCH50%) no significant differences were found between patients with and without LN. Anti-C1q > 40 U/ml showed a statistically significant association with LN and had 80% of specificity. Cut-off values for LN identified by Receiver Operating Characteristic curves (ROC) were higher for anti-dsDNA (> 455 IU/ml) and antinucleosome (>107 U/ml), lower for CH50 (< 150 UCH50%) and, for anti-C1q (> 41 U/ml) coincided with the cut-off values accepted for SLE. Anti-C1q > 134 U/ml had a 92% of specificity, 56% of sensibility and was associated with a fifteen-fold increased risk of LN. The simultaneous presence of anti-nucleosome > 107 U/ml and anti-C1q > 134 U/ml was associated with a 27-fold higher probability for LN. According to these results, the cut-off values used to detect SLE activity could be inadequate to identify patients at high risk of severe LN. PMID- 30285926 TI - [Immunotherapy in cancer. Current prospects, challenges and new horizons]. AB - Recent understanding of the mechanisms that control immune system homeostasis and orchestrate antitumor responses has prompted the development of novel immunotherapeutic modalities. These include antibodies that target immune checkpoints such as PD-1/PD-L1 and CTLA-4, agonistic antibodies of costimulatory molecules such as CD137 and OX-40 and the adoptive transfer of genetically modified antitumor T cells. However, a large number of patients do not respond to these therapies and develop resistance as a result of activation of compensatory circuits. Rational combination of immunotherapeutic modalities will help overcome resistance and will increase the number of patients who will benefit from these treatments. Moreover, identification of predictive biomarkers will allow selection of patients responding to these treatments. Emerging clinical trials and pre-clinical studies have shown exciting results anticipating new horizons in the design and implementation of cancer immunotherapeutic modalities. PMID- 30285927 TI - [Cardiovascular risk of non-steroidal anti-inflammatory drugs]. AB - Non-steroidal anti-inflammatories (NSAIDs) are among the most commonly used drugs in clinical practice. They block cyclooxygenases (COX) enzymes, but the degree of inhibition of COX-1 and COX-2 varies between them. In general, NSAIDs are classified in selective COX-2 or coxibs and non-selective or traditional NSAIDs. Both the analgesic and antiinflammatory effects, as well as the cardiovascular adverse effects, depend on the COX-2 inhibition. This paper reviews the available evidence of the increased risk of thrombotic events for both coxibs and traditional NSAID. The prothrombotic effect could be due to the inhibition of endothelial COX-2, with a decrease in production of prostacyclin and a relative increase in platelet thromboxane levels. Coxibs and diclofenac 150 mg/day seem to increase the risk of major vascular events by more than a third. Ibuprofen 2400 mg/day could slightly increase the risk of coronary events. Naproxen 1000 mg/day apparently does not increase the risk of vascular events. Besides ibuprofen and naproxen have the potential to decrease the cardioprotective effect of low doses of aspirin. Naproxen (= 1000 mg/day) and low doses of ibuprofen (= 1200 mg/day) are considered to have the most favorable thrombotic cardiovascular safety profiles of all NSAIDs. Therapeutic decisions should be based on an assessment of a person's individual risk factors, using the safest NSAIDs, at the lowest effective doses, for the shortest duration necessary to control symptoms, restricting their use in patients with increased cardiovascular risk. PMID- 30285928 TI - [Fatal spotted fever in Salta province]. AB - We describe the case of a 17-year-old male patient living in Salta city who, 10 days after visiting a rural area in Salta province, was hospitalized for febrile seizures. Shortly after admission, he developed an exanthema followed by a multiple organ dysfunction that evolved to irreversible septic shock followed by death 48 hours after admission. Serological diagnosis -high IgM and IgG anti Rickettsia spp. antibody titres as detected by indirect immunofluorescence- arrived post mortem. Spotted fever group rickettsioses are tick-borne diseases distributed worldwide and continue being under diagnosed in several countries mainly due to a low clinical suspicion. In the north-western provinces of Argentina there is also the limitation of not counting with a regional laboratory to perform the etiological diagnosis. This is crucial because the severe forms of the disease, which are commonly caused by R. rickettsii, have been already documented in the region. Given that spotted fevers have broadly unspecific febrile presentations and the components of the enzootic cycle are present even in geographic areas not yet considered to be endemic for tick borne diseases, their diagnosis should not be underestimated. If the adequate antibiotic treatment is administered timely, the prognosis of this group of life-threatening diseases improves drastically. PMID- 30285929 TI - [Dermatomyositis associated with anti-MDA5 autoantibody]. AB - Dematomyositis is an idiopathic inflammatory myopathy with a variable clinical spectrum. In recent years, a number of myositis-specific antibodies have been identified including anti-MDA5, which is us eful for diagnosis, prognosis and classification of the diverse clinical forms of the disease. This antibody is associated with cutaneous ulcers, rapidly progressive interstitial lung disease, early mortality and poor prognosis, so the detection of this antibody in a suitable clinical context, raises the need for an aggressive immunosuppressive treatment. We describe a case of dermatomyositis classified as hypomyopathic (i.e. involving mild muscle weakness), presenting specific skin lesions, interstitial lung disease, and presence of anti-MDA5 antibody that had a favorable response to combined treatment with cyclophosphamide, gamma globulin and corticosteroids. PMID- 30285930 TI - [Lateral medullary stroke with extracranial course of the postero- inferior cerebellar artery]. AB - We present two cases of lateral medullary stroke in subjects with extracranial trajectory of the postero-inferior cerebellar artery. Case 1: a 21-year-old male who presented ataxia and right dysmetria after cervical trauma in a rugby match. Case 2: 56-year-old woman, who started with vertigo and left hemiparesis after intense physical effort. In both cases, the angiographic studies showed an extracranial trajectory of the posterior inferior cerebellar artery. This vessel rarely originates below the foramen magnum, in close relationship with the first three cervical vertebrae and the atlanto-axial joint. At this level, it is exposed to mechanical damage causing dissection, such as direct trauma, abrupt cervical manipulation or prolonged cephalic extension. Therefore, this association should be considered in patients with stroke of the lateral region of the bulb and extracranial trajectory of the posterior-inferior cerebellar artery. PMID- 30285931 TI - [Blue toe syndrome as a clinical finding of pheochromocytoma]. AB - Pheochromocytomas are tumors that arise from chromaffin cells of the sympathetic nervous system and act by synthesizing and releasing catecholamines. They usually occur between the fourth and fifth decade of life and have a very wide clinical presentation. They occur only in 0.1-0.2% of the hypertensive population and represent a treatable and curable cause of arterial hypertension, as well as other symptoms derived from the uncontrolled secretion of catecholamines. Peripheral arterial ischemia secondary to massive amines release by a pheochromocytoma is a very uncommon condition. Here we report a case of pheochromocytoma manifested as blue finger syndrome in a patient with palpable distal pulses and history of poor blood pressure control despite treatment with two drugs.

AB - Deep vein thrombosis (DVT) of the upper limb is a rare entity, estimated to account for 10% of all cases of DVT. Classically, they are classified into primary (idiopathic, due to subclavian vein compression or exercise related) and secondary (cancer, thrombophilia, trauma, shoulder surgery, associated to venous catheters or due to hormonal causes). The Paget- Schrotter syndrome is a primary thrombosis of the subclavian vein in the subclavian-axillary junction, related either to repetitive movements or to exercise; leading to microtrauma in the endothelium with consequent activation of the coagulation cascade. Clinically, it presents abruptly with pain, edema and feeling of heaviness in the affected limb. The treatment varies from thrombolytics and anticoagulation to surgical intervention, depending on the time of evolution. We present four cases of exercise-related subclavian vein thrombosis.

PMID- 30285938 TI - Yesterday masked, today modified; what do mycotoxins bring next? AB - Mycotoxins are secondary metabolites produced by toxigenic fungi in crops worldwide. In (micro)organisms such as plants, fungi, bacteria, or animals they may be further metabolised and modified, but this is also true for food processing, which may lead to a wide range of masked mycotoxin forms. These often remain undetected by analytical methods and are the culprits for underestimates in risk assessments. Furthermore, once ingested, modified mycotoxins can convert back to their parent forms. This concern has raised the need for analytical methods that can detect and quantify modified mycotoxins as essential for accurate risk assessment. The promising answer is liquid chromatography-mass spectrometry. New masked mycotoxin forms are now successfully detected by iontrap, time-of-flight, or high-resolution orbitrap mass spectrometers. However, the toxicological relevance of modified mycotoxins has not been fully clarified. PMID- 30285939 TI - Whole blood exchange transfusion as a promising treatment of aluminium phosphide poisoning. AB - A 37-year-old male was referred to us about one hour after deliberate ingestion of two 3-gram aluminium phosphide (ALP) tablets. Three hours after admission, his blood pressure dropped to 85/55 mmHg, his heart rate increased to 120 bpm, O2 saturation dropped to 82 %, and the electrocardiogram showed junctional rhythm. We started whole blood exchange, and gross haematuria and jaundice ensued. However, his blood pressure increased, arrhythmia resolved itself, and he was extubated two days after the transfusion was completed. He was sent home seven days after admission completely symptom-free. We believe this treatment may be successfully applied in ALP-poisoned patients. PMID- 30285940 TI - How sulphur dioxide and storage temperature contribute to patulin degradation in homemade apple juice. AB - Mycotoxin patulin is one of the quality indicators for apple juice. Like other mycotoxins, it raises consumer health concerns. The issue of low quality is particularly relevant for apples provided by small producers, whose quality control may not be standardised. As sulphur dioxide (SO2) is common in fruit preservation against fungi, the aim of this study was to determine how efficient it is in degrading patulin in apple juices stored in real-life conditions. This included refrigerated (4 degrees C) and non-refrigerated warehouses/environments (30 degrees C) over 8, 10, 12, and 20 weeks of storage. Apple juice was diluted to 0.010 MUg g-1, 0.050 MUg g-1, and 0.100 MUg g-1 of patulin. SO2 was added to each sample in the amounts of 250 MUg mL-1 and 50 MUg mL-1. Untreated juice samples for each patulin concentration served as controls under the same experimental conditions. Patulin content was determined with high performance liquid chromatography. The best degradation was observed with 250 MUg mL-1 of SO2 at 30 degrees C regardless of the patulin baseline concentration. Although treatment with SO2 and refrigeration did not fully remove patulin, it was highly efficient over twelve weeks of storage. Our results suggest that patulin levels can be reduced between 33 and 100 % at 30 degrees C and up to 100 % at 4 degrees C. PMID- 30285941 TI - A new approach to assessing occupational exposure to antineoplastic drugs in hospital environments. AB - Cytotoxic antineoplastic drugs (ADs) pose occupational risk and therefore require safe handling practices. We created, optimised, and validated an innovative monitoring protocol for simultaneously assessing 21 ADs in the healthcare environment, and also proposed surface exposure levels (SELs) to facilitate the interpretation of monitoring results, as there are currently no occupational exposure limits for ADs. The environmental AD monitoring data were collected in nine Italian hospitals between 2008 and 2017 and include 74,565 measurements in 4,814 wipe samples. Excellent overall recovery and sensitivity of the analytical methods along with innovative desorption automation make this protocol useful for routine monitoring. AD contamination was found in 3,081 measurements, confirming potential exposure in healthcare workers. Samples taken at the beginning and the end of work shifts, allowed to calculate 75th and 90th percentile values for each ADs both in preparation and administration units and we created a traffic-light colour-coding system to facilitate interpretation of the findings. The introduction of SELs will provide a solid basis for improving occupational safety and focusing on contamination control. PMID- 30285942 TI - Clara cell protein 16 release from the nasal mucosa in allergic rhinitis, chronic rhinosinusitis, and exposure to air pollutants. AB - Clara cell protein 16 (CC16) is a small protein mainly produced by non-ciliated Clara cells in the respiratory epithelium. It has an anti-inflammatory role in chronic upper and lower airway eosinophilic inflammations. Decreased levels of CC16 are found in the nasal secretions and plasma of patients with chronic eosinophilic inflammatory disorders, such as asthma, allergic rhinitis, and chronic rhinosinusitis with or without nasal polyps, as well as in people exposed to high levels of air pollutants. Intranasal corticosteroid administration suppresses chronic inflammation of the nasal mucosa driven by eosinophils and stimulates local CC16 production. CC16 can be a reliable biomarker of the beneficial effects of perennial allergic rhinitis and chronic rhinosinusitis therapy and of the functional recovery of the nasal mucosa after treatment with topical glucocorticoids. PMID- 30285943 TI - Occupational exposure to bioburden in Portuguese bakeries: an approach to sampling viable microbial load. AB - In bakeries, a number of operations such as mixing are associated with exposure to air-suspended flour dust and related bioburden. The aim of this study was to find the best active sampling approach to the assessment of occupational exposure to bioburden in Portuguese bakeries based on the data obtained with the use of specific impaction and impinger devices. We used impaction to collect fungal particles from 100 L air samples onto malt extract agar (MEA) supplemented with chloramphenicol (0.05 %). For growing fungi we also used dichloran glycerol (DG18) agar-based media and for mesophilic bacteria we used tryptic soy agar (TSA) supplemented with nystatin (0.2 %). For Enterobacteriaceae we used violet red bile agar (VRBA). With impingers we also collected 300 L air samples at the 300 L/min airflow rate, inoculated onto the same culture media. The two methods, impaction and impinger, showed statistically significant differences in the following counts: fungal on MEA (z=-2.721, p=0.007), fungal on DG18 (z=-4.830, p=0.000), total bacteria (z=-5.435, p=0.000), and Gram-negative coliforms (z= 3.716, p=0.000). In all cases the impaction method detected significantly higher concentrations than the impinger method. Fungal and bacterial loads were higher in the production unit and lower in the shop. The fungal load obtained with impaction varied between 10 and 5140 CFU m-3, and total bacterial counts ranged between 10 and 4120 CFU m-3. This study has shown that the impaction method is the best active sampling approach to assessing viable bioburden in this specific occupational environment, but a multi-faceted approach to sampling and analyses combining methods and media enables a more refined risk characterisation and, consequently, better tailored risk control measures to reduce adverse health outcomes in workers. PMID- 30285944 TI - Occupational exposure to cytotoxic drugs: the importance of surface cleaning to prevent or minimise exposure. AB - Healthcare workers who prepare or administer cytotoxic agents run the risk of exposure, and the risks for health are real even at doses lower than those applied in cancer patients, because, in theory, no dose is safe. The most common and problematic route of exposure is through the skin, especially as work surfaces can remain contaminated even after cleaning. This pilot study aimed to demonstrate the importance of having an effective surface decontamination protocol by determining surface contamination with cyclophosphamide, 5 fluorouracil, and paclitaxel as the most common cytotoxic drugs in an oncology day service. Samples were collected before and after drug handling and analysed with high performance liquid chromatography with diode array detection (HPLC DAD). Of the 29 samples collected before drug handling 23 were contaminated, five of which with more than one drug. Of the 30 samples collected after drug handling 25 were contaminated, eight of which with more than one drug. The two time points did not significantly differ, which evidences a widespread contamination and ineffective cleaning. This calls for revising the cleaning protocol and handling procedure to place contamination under control as much as possible. PMID- 30285945 TI - Employment status of workers with a diagnosed occupational disease in Croatia: a 10-year trend (2005-2014). AB - Occupational diseases (ODs) often have a chronic, progressive course, resulting in reduced work capacity and quality of life, prolonged sick leaves, unemployment, early retirements, and disability claims. The aim of this retrospective study was to see how diagnosed ODs affected the employment of 95 Croatian workers between 2005 and 2014. To do that, we reviewed archived data and made a telephone survey. The lowest age at which an OD was diagnosed was 20 years in women and 22 in men, while the shortest duration of work before OD diagnosis was one year for both genders. The most common ODs were overuse syndromes on the arms, carpal tunnel syndrome in particular, diagnosed mostly in textile and office workers. Of the 95 participants, 12 lost their jobs since the OD diagnosis, 46 retired, and 37 continued to work. Significantly more participants became unemployed after OD diagnosis in the period 2010-2014 than 2005-2009 (9 out of 43, 21 %, vs. 3 out of 52, 6 %, P<0.05). Only five participants were included in an occupational rehabilitation programme. Our findings warn against the deterioration in care for workers diagnosed with OD in Croatia. PMID- 30285946 TI - Urban honey - the aspects of its safety. AB - To contribute to the development of urban beekeeping, we designed this study to obtain more information about the contamination of urban bee products with toxic metals, polycyclic aromatic hydrocarbons (PAHs), and pesticides. The samples of honey (N=23), pollen (N=13), and floral nectar (N=6) were collected from the experimental stationary apiary of the Belgrade University Faculty of Agriculture located in centre of Zemun (a municipality of the Belgrade metropolitan area) in 2015 and 2016. Metals (Pb, Cd, As, Cu, Zn, Fe, Mn, Ni, Cr, and Hg) were determined with inductively coupled plasma quadrupole mass spectrometry (ICP QMS). Polycyclic aromatic hydrocarbons (PAHs) were analysed with high-performance liquid chromatography with fluorescence detection (HPLC-FLD). Pesticides were analysed with gas chromatography - mass spectrometry (GC-MS). The honey samples were generally within the European and Serbian regulatory limits. The levels of all the 123 analysed pesticides were below the limit of quantification (LOQ). Regarding PAH levels in honey, the highest content was found for naphthalene. The elevated levels of Hg and Cr and of PAHs in the pollen samples indicated air pollution. Pesticide residues in pollen, however, were below the LOQ. In nectar, metal levels were relatively similar to those in honey. Our results suggest that the investigated urban honey meets the regulatory requirements for metals, PAHs, and pesticides and is therefore safe for consumption. PMID- 30285947 TI - Teaching about diagnostic errors through virtual patient cases: a pilot exploration. AB - BACKGROUND: Diagnostic error is a major problem in health care, yet there are few medical school curricula focused on improving the diagnostic process and decreasing diagnostic errors. Effective strategies to teach medical students about diagnostic error and diagnostic safety have not been established. METHODS: We designed, implemented and evaluated a virtual patient module featuring two linked cases involving diagnostic errors. Learning objectives developed by a consensus process among medical educators in the Society to Improve Diagnosis in Medicine (SIDM) were utilized. The module was piloted with internal medicine clerkship students at three institutions and with clerkship faculty members recruited from listservs. Participants completed surveys on their experience using the case and a qualitative analysis was performed. RESULTS: Thirty-five medical students and 25 faculty members completed the survey. Most students found the module to be relevant and instructive. Faculty also found the module valuable for students but identified insufficient curricular time as a barrier to implementation. CONCLUSIONS: Medical students and faculty found a prototype virtual patient module about the diagnostic process and diagnostic error to be educational. PMID- 30285948 TI - Antecedents of red cell transfusion in a large contemporary obstetric cohort. AB - Background Hemorrhage is a critical contributor to maternal morbidity but estimation of blood loss at delivery is frequently inaccurate. Due to this inaccuracy we sought to examine blood transfusion as a surrogate marker for morbidity in a large non-population based consecutive cohort. Methods A retrospective analysis of prospectively gathered data was carried out at two university institutions serving a heterogeneous urban obstetric population from January to December 2016. Data were analyzed to determine whether individual characteristics were associated with perinatal transfusion. Hematological indices and requirement for other blood products were also characterized. Results A total of 16,581 deliveries were recorded during the study and 1.7% (289/16,581) of the cohort required red cell transfusion. Those who received transfusion were more likely to be nulliparous, and to deliver <37 weeks' or >42 weeks' gestation. They were also more likely to have a macrosomic infant (birthweight >4 kg) and to have had a multiple pregnancy. Characteristics not associated with risk of transfusion included obesity [18% (52/289) vs. 15% (2445/16,292); P=0.18], and maternal age >=35 years [28% (82/289) vs. 33% (5537/16,292); P=0.05]. Additional blood products were necessary in a small number of patients who received red cells. Conclusions The rate of transfusion in a contemporary Irish cohort has risen compared with previous data. Several variables associated with transfusion are consistent with older studies but importantly; maternal obesity and advanced maternal age are not associated with transfusion. These data may encourage the investment of resources in a population previously considered low-risk and, following future studies, to improve strategies aimed at limiting blood transfusion.

AB - The menace of cholera epidemic occurrence in Yemen was reported in early 2017. Recent reports revealed that an estimated 500,000 people are infected with cholera whereas 2,000 deaths have been reported in Yemen. Cholera is transmitted through contaminated water and food. Yemen is the least developed country among the Middle East countries in terms of wastewater and solid waste management. The population of Yemen is about 24.5 million and generates about 70-100 million m3 of sewage. An estimated 7% of the population has sewerage systems. It has been revealed that 31.2 million m3 of untreated sewage is used for irrigation purposes especially for vegetables and Khat trees. In addition, more than 70% of the population in Yemen has no potable water. They depend on water wells as a water source which are located close to sewage disposal sites. The present review focuses on the current status of water, wastewater as well as solid waste management in Yemen and their roles in the outbreak of cholera. Future prospects for waste management have been proposed. PMID- 30285951 TI - Natural organic matter as precursor to disinfection byproducts and its removal using conventional and advanced processes: state of the art review. AB - Natural organic matter (NOM) is ubiquitous in the aquatic environment and if present can cause varied drinking water quality issues, the major one being disinfection byproduct (DBP) formation. Trihalomethanes (THMs) are major classes of DBP that are formed during chlorination of NOM. The best way to remove DBPs is to target the precursors (NOM) directly. The main aim of this review is to study conventional as well as advanced ways of treating NOM, with a broad focus on NOM removal using advanced oxidation processes (AOPs) and biofiltration. The first part of the paper focuses on THM formation and removal using conventional processes and the second part focuses on the studies carried out during the years 2000-2018, specifically on NOM removal using AOPs and AOP-biofiltration. Considering the proven carcinogenic nature of THMs and their diverse health effects, it becomes important for any drinking water treatment industry to ameliorate the current water treatment practices and focus on techniques like AOP or synergy of AOP-biofiltration which showed up to 50-60% NOM reduction. The use of AOP alone provides a cost barrier which can be compensated by the use of biofiltration along with AOP with low energy inputs, making it a techno economically feasible option for NOM removal. PMID- 30285952 TI - Sick leave due to diarrhea caused by contamination of drinking water supply with Cryptosporidium hominis in Sweden: a retrospective study. AB - We investigated sick leave from work, studies, preschool, and kindergarten occurring between 1 November 2010 and 31 January 2011 and associated with a waterborne outbreak of diarrhea caused by Cryptosporidium hominis in late November 2010 in Ostersund, Sweden with 45.2% of 60,000 residents being symptomatic. A questionnaire defining acute watery diarrhoea and/or >=3 diarrhea episodes/day as cryptosporidiosis was sent to 1,508 residents in late January 2011 (response rate 69.2%). Among adults aged 18-60 years, 24.0% took sick leave for a mean of 4.6 (SD +/- 4.0) days due to cryptosporidiosis, and an additional 10.6% were absent from work a mean of 4.0 (+/-2.2) days to care for symptomatic children. Among children (aged <=17 years), 35.0% stayed home sick from kindergarten/preschool or school/university for a mean of 5.2 (+/-3.8) days resulting in 5.1 (+/-4.4) days of absence from work per sick child shared between parents/guardians. The estimated total number of sick leave days was 50,000 for adults and 20,700 for children, with an estimated direct cost of ?7 million for employers. The potential impact on society of sick leave caused by waterborne diseases must be considered in decisions regarding the quality of drinking water. PMID- 30285953 TI - Categorical performance characteristics of method ISO 7899-2 and indicator value of intestinal enterococci for bathing water quality monitoring. AB - Intestinal enterococci indicate the fecal contamination of bathing waters. This study defines the performance characteristics of the reference method ISO 7899 2:2000 with water samples collected from inland and coastal bathing areas in Finland. From a total of 341 bacterial isolates grown on Slanetz and Bartley medium, 63.6% were confirmed as intestinal enterococci on bile aesculin agar. The partial 16S rRNA gene sequences showed that Enterococcus faecium and Enterococcus faecalis clades accounted for 93.1% of the confirmed isolates. The range of the false positive and false negative rate of the ISO 7899-2 was 0.0-18.5% and 5.6 57.1%, respectively, being affected by the presumptive colony count on the membrane. The analysis of multiple sample volumes is proposed to reach 10-100 colonies per membrane when 47 mm diameter membranes are used to prevent overestimation of low counts and underestimation of the high counts. PMID- 30285954 TI - Association of water quality with soil-transmitted helminthiasis and diarrhea in Nueva Santa Rosa, Guatemala, 2010. AB - Improved water quality reduces diarrhea, but the impact of improved water quality on Ascaris and Trichuris, soil-transmitted helminths (STH) conveyed by the fecal oral route, is less well described. To assess water quality associations with diarrhea and STH, we conducted a cross-sectional survey in households of south eastern Guatemala. Diarrhea was self-reported in the past week and month. STH was diagnosed by stool testing using a fecal parasite concentrator method. We explored associations between Escherichia coli-positive source water (water quality) and disease outcomes using survey logistic regression models. Overall, 732 persons lived in 167 households where water was tested. Of these, 79.4% (581/732) had E. coli-positive water, 7.9% (58/732) had diarrhea within the week, 14.1% (103/732) had diarrhea within the month, and 6.6% (36/545) tested positive for Ascaris or Trichuris, including 1% (6/536) who also reported diarrhea. Univariable analysis found a statistically significant association between water quality and STH (odds ratio [OR] = 5.1, 95% confidence interval [CI] = 1.1-24.5) but no association between water quality and diarrhea. Waterborne transmission and effects of water treatment on STH prevalence should be investigated further. If a causal relationship is found, practices such as household water treatment including filtration might be useful adjuncts to sanitation, hygiene, and deworming in STH control programs. PMID- 30285955 TI - Assessment of the parasitological quality of water stored in private cisterns in rural areas of Tunisia. AB - Limited access to safe water enhances poverty, hunger and diseases. This study evaluated the drinking water quality stored in home-based systems, located in rural areas of Tunisia. Water management was also documented as an improvement of good practice as most of the water contamination could be related to behavioral patterns. Thirty-nine water samples from five different sources (rainwater, truck cistern, mix, etc.) were screened for enteric parasitic contamination with the modified Bailenger technique. This technique allowed the detection of three protozoa: Giardia spp.; Entamoeba histolytica/dispar/moshkovskii; Entamoeba coli and one helminth specie: Ascaris spp. The overall prevalence of these intestinal parasites was approximately 97% with a relatively high frequency of protozoa over helminths and more specifically E. histolytica/dispar/moshkovskii. This incidence could be correlated to the lack of hygiene practices, sanitation and education. This situation requires the need for frequent monitoring of the water quality and management in these areas. PMID- 30285956 TI - Computational fluid dynamics analysis of the hydraulic (filtration) efficiency of a residential swimming pool. AB - Hydraulic or filtration efficiency of residential swimming pools, quantified in terms of residence time characteristics, is critical to disinfection and thus important to public health. In this study, a three-dimensional computational fluid dynamics model together with Eulerian and Lagrangian-based techniques are used for investigating the residence time characteristics of a passive tracer and particles in the water, representative of chemicals and pathogens, respectively. The flow pattern in the pool is found to be characterized by dead zone regions where water constituents may be retained for extended periods of times, thereby potentially decreasing the pool hydraulic efficiency. Two return-jet configurations are studied in order to understand the effect of return-jet location and intensity on the hydraulic efficiency of the pool. A two-jet configuration is found to perform on par with a three-jet configuration in removing dissolved constituents but the former is more efficient than the latter in removing or flushing particles. The latter result suggests that return-jet location and associated flow circulation pattern have an important impact on hydraulic efficiency. Thus return-jet configuration should be incorporated as a key parameter in the design of swimming pools complementing current design standards. PMID- 30285957 TI - Faecal contamination in public pools in Barcelona province: Cryptosporidium spp. and bacterial indicators. AB - A study was conducted of the occurrence of Cryptosporidium in indoor heated public swimming pools and of three bacterial indicators (Escherichia coli, faecal enterococci and Clostridium perfringens) on pool surrounds. Although all examined pools adhered strictly to the Spanish regulations, the influence of several parameters related to water conditions, pool structure, users and location on the presence of protozoa and bacteria was analysed. Cryptosporidium was detected in 18.8% of pools in 60% of the five towns studied. The maximum concentration was 13 oocysts/L in one swimming pool and one Jacuzzi. The bacterial indicators' prevalence on pool surrounds was higher than 50%, being present in all of the towns. Plastic surfaces presented the lowest bacterial prevalence, whereas painted surfaces were 100% positive. No differences were observed for pool surrounds with autonomous or disabled users. Risk of cryptosporidiosis in pool vessels indicated that concentrations over 1 oocyst/10 L enhance the risk of infection, even in one exposure. Guidelines for managing faecal accidents and public information on the importance of good hygiene behaviours in and around swimming pools are recommended to limit oocysts' presence. PMID- 30285958 TI - Photocatalytic degradation of reactive black 5 on the surface of tin oxide microrods. AB - A simple co-precipitation technique is proposed for synthesis of tin oxide (SnO2) microrods. Stannous chloride and urea were used during synthesis. X-ray powder diffraction (XRD) analysis revealed that the annealed product consists of SnO2 microrods having tetragonal unit cells, while scanning electron microscopy (SEM) analysis revealed the rod-like morphology of a synthesized product. These synthesized microrods are used as photocatalyst for the degradation of reactive black 5 (RB5). Degradation kinetics of RB5 are monitored under daylight in different concentrations of hydrogen peroxide (H2O2) and catalyst. The percentage of RB5 conversion is also calculated at various concentrations of hydrogen peroxide and catalyst which demonstrate that RB5 shows high catalytic degradation at high concentrations of hydrogen peroxide and catalyst. PMID- 30285959 TI - Contamination of arsenic, manganese and coliform bacteria in groundwater at Kushtia District, Bangladesh: human health vulnerabilities. AB - Safe water is essential for life. Consumption of arsenic and manganese contaminated water poses a range of health effects to humans. Physico-chemical and bacteriological characteristics of groundwater at five administrative upazillas in Kushtia District, Bangladesh, have been studied to evaluate the potability of water for drinking purpose from 32 randomly selected tube wells (TWs). APHA (2012) standard analytical methods were applied for analyses of the physico-chemical and bacteriological parameters of the water samples. Arsenic, iron, and manganese content were analyzed by atomic absorption spectroscopy (AAS). The investigated parameters of water samples were found as pH 6.81-8.12, electrical conductivity (EC) 520-1,995 MUs/cm, total dissolved solids (TDS) 357.8 1,372.6 mg/L, chloride 10-615 mg/L, total hardness 285-810 mg/L, arsenic (As) 0.001-0.098 mg/L, iron (Fe) 0.04-1.45 mg/L, manganese (Mn) 0.01-6.32 mg/L. About 56.25% of TWs were highly contaminated with fecal coliform (FC) and 68.75% were found to be contaminated with total coliform (TC). Results were compared with World Health Organization (WHO) and Bangladesh Drinking Standards (BDS). The concentrations of water quality parameters are much higher as compared to WHO and BDS standards. This may cause acute public health risks and make water unsuitable for direct human consumption without treatment. PMID- 30285960 TI - Ultraviolet A and B wavelength-dependent inactivation of viruses and bacteria in the water. AB - UVA and UVB can be applied to solar disinfection of water. In this study, the inactivation and photoreactivation of viruses and bacteria in the UVA-B range were analyzed. MS2 and T4 bacteriophages, and Escherichia coli were used as surrogates to quantify dose-response behaviors. Inactivation in UVC was used to validate the methodology and to expand the inactivation action spectra. The results showed log-linear inactivation for MS2 and T4 in the 254-320 nm wavelength range. T4 inactivation was consistently faster than MS2 (except at 320 nm), and for both phages, inactivation decreased with increasing wavelength. The dose-response of bacteria exhibited a lag at low doses, possibly because the photons must strike a discrete number of critical targets before growth stops. A tail was present at high doses for some wavelengths, perhaps due to clumping or the presence of subgroups with higher resistance. The inactivation action spectra for bacteria exhibited a reduction in inactivation as wavelength increased. No bacterial inactivation was observed beyond 320 nm at doses applied. After inactivation at 297 nm (UVA), bacteria regained viability through photoreactivation, and repair increased with increase in photoreactivating light exposure time. This implies additional doses above inactivation thresholds are required to cause irreversible damage. These results are useful for designing solar disinfection systems. PMID- 30285961 TI - Isolation and molecular identification of Acanthamoeba spp. from hot springs in Mazandaran province, northern Iran. AB - Acanthamoeba is a free-living protozoan that can be found in natural and artificial environments such as hot tubs, surface water and springs and can cause severe diseases including amoebic keratitis and granulomatous amoebic encephalitis. The present study was conducted owing to the lack of research regarding genotypes of Acanthamoeba in hot springs of Mazandaran province in northern Iran. Twenty-four water samples were collected from all hot springs in Mazandaran province. After filtration through nitrocellulose membrane, samples were cultured on non-nutrient agar medium enriched with TYIS-33. The cultures were microscopically examined for the presence of Acanthamoeba. Positive cultures were analysed by polymerase chain reaction (PCR) and genotypes were determined by targeting the 18 S rRNA gene. The pathogenic potential of all positive isolates was identified using thermotolerance and osmotolerance tests. Eleven (47.8%) samples were positive for Acanthamoeba. Based on sequencing analysis, 100% of isolates belonged to the T4 genotype. Thermo- and osmo-tolerance tests showed that four (36.3%) Acanthamoeba strains were highly pathogenic. According to our research, the occurrence of Acanthamoeba in recreational hot springs could be a hazard for high risk persons. Posting warning signs and regular monitoring of these waters by health planners may therefore be useful for decreasing Acanthamoeba spp. infections. PMID- 30285962 TI - Preparation, adsorptive properties and chemical regeneration studies of high porous activated carbon derived from Platanus orientalis leaves for Cr(VI) removal. AB - Activated carbon (AC) was prepared from Platanus orientalis leaves by H3PO4 activation using a microwave heating method and characterized by SEM (scanning electron microscopy), Brunauer-Emmett-Teller (BET) surface area analysis and FTIR (Fourier transform infrared spectroscopy) techniques. AC exhibited a surface area of 1089.67 m2/g and a relatively high pore volume of 1.468 cm3/g. Utilization of AC for the removal of Cr(VI) from aqueous solution was researched. The adsorption efficiency was highly pH dependent and adsorption capacity of AC for Cr(VI) could reach up to 135.24 mg/g. Adsorption equilibrium could be quickly reached within 2 h. A kinetic study indicated that the adsorption of Cr(VI) conformed to the pseudo-second-order model (R2 > 0.99). An intraparticle diffusion model was applied to describe the adsorption kinetics, and the results showed that there are other factors that affect the rate. Chemical regeneration for AC saturated with Cr(VI) was performed and HNO3 displayed the best regeneration performance among the four chemical regeneration agents (HNO3, H2SO4, NaOH, NaCl). The regeneration performance increased at first and then decreased with the rise of HNO3 concentration, and regeneration reaction could reach equilibrium within 4 h in the first cycle. The FTIR spectra revealed that HNO3 successfully introduced N H bonds onto the AC surface in the regeneration process. PMID- 30285963 TI - Drinking water in West Virginia (USA): tap water or bottled water - what is the right choice for college students? AB - West Virginia has had a history of water quality issues. In parallel, the world is facing a plastic pollution crisis. In order to better understand behavioral responses to perceived water quality, a survey was conducted at a major research university to ask participants about water quality perceptions and drinking water behaviors. A total of 4,188 students completed the survey during the Spring 2017 semester. Logistic regression analyses were used to predict behaviors. Results indicated that a third of the student population primarily used bottled water for drinking purposes at home, while 39% used a filter at home and 26% drank water directly from the tap. On campus, bottled water use was reported by 36% of the students, water fountain use represented 31%, and 29% of the students brought their own water with reusable cups/bottles. Health risk perceptions, organoleptic perceptions (i.e., taste, odor, color), and environmental concern were predictors of the different behaviors. Students originally from West Virginia had a higher propensity of using bottled water. We argue that bottled water consumption should be reduced in areas where water quality is not an issue. In this sense, there is a need for education among the student population in West Virginia. PMID- 30285964 TI - Monitoring levels of viable Helicobacter pylori in surface water by qPCR in Northeast Spain. AB - Helicobacter pylori infection is a risk factor for chronic active gastritis, peptic ulcers, gastric carcinoma and lymphoma. Although the infection may be acquired through different transmission routes, the presence and viability of H. pylori in water sources are not well known. Therefore, the aim of our study was to analyse the viability of H. pylori cells in urban surface waters collected at the Vallparadis public park in Terrassa, Barcelona, Spain. The water samples were analysed by viability quantitative polymerase chain reaction (qPCR) using propidium monoazide and specific primers for the H. pylori vacuolating cytotoxin (vacA gene). Viable H. pylori were found in 91.3% of the samples analysed, with an average concentration of 3.46 +/- 1.06 log cell 100 mL-1. Our work proves a quick and simple procedure for evaluating viable H. pylori cells in environmental samples by qPCR. Furthermore, the results provide evidence that urban surface waters may contain considerable levels of viable H. pylori cells, thus indicating they are a potential source of infection, which represents a public health concern. PMID- 30285965 TI - Degradation of rhodamine B with manganese dioxide nanorods. AB - This is an investigation on oxidative degradation of rhodamine B (RhB) by manganese dioxide (MnO2) nanorods synthesized by redox co-precipitation method. Field emission scanning electron microscopy of MnO2 nanorods at an electron voltage of 10 kV revealed a rod-like morphology for the synthesized nanoparticles. Fourier transform infrared spectra exhibited characteristic peaks of MnO2. Surface area of MnO2 nanorods was 277 m2/g. Effect of various parameters like initial concentration and pH of RhB solution, time of contact between MnO2 nanorods and RhB, dosage of MnO2, and stirring speed on decolouration of RhB was evaluated in batch experiments. Rapid decolouration in the initial period of the reaction was observed due to the adsorption of RhB molecules onto the surface of MnO2 nanorods followed by oxidative degradation. Percentage decolouration decreased with increase in initial concentration and increased with increase in dosage, speed of stirring the mixture and with increase in pH up to pH 7. Near complete decolouration was achieved at a dose of 0.5 g/L of MnO2 nanorods from 20 mg/L RhB solution within 3 min. Observations fitted best to the pseudo second order kinetic model. This study could pave the way for development of cost effective, nontoxic nanostructures for treatment of wastewaters containing RhB. PMID- 30285966 TI - Molecular surveillance of Cryptosporidium and Giardia duodenalis in sludge and spent filter backwash water of a water treatment plant. AB - The purpose of this study was to monitor the presence of Cryptosporidium spp. and Giardia duodenalis in a water treatment plant (WTP) using settling sludge and backwash water (BW) samples in previous and post the deflocculation of polyaluminium chloride (PAC) flacks. Eleven collections were performed. BW and settling sludge (SSF) were concentrated by calcium carbonate flocculation, and another aliquot of settling sludge (SSC) by centrifugation. The samples were divided as follows: Group A, containing 33 samples without degradation of PAC flakes, and Group B, with degradation by alkalinization with 10 M NaOH. Sample DNA was extracted with a commercial kit, and nested polymerase chain reaction (PCR) was used to detect Cryptosporidium and G. duodenalis. All samples from Group A were negative for Cryptosporidium spp., and 6.1% (2/33) were positive for G. duodenalis in SSC samples. While the absence of Cryptosporidium may be due to a low contamination level of the water resource, the presence of G. duodenalis indicates contamination of the raw water. The detection of G. duodenalis in SSC samples indicates that this detection method was the most effective. The 33 samples from Group B were negative for both protozoa, probably due to the presence of aluminium and humic substances.

AB - A 26-year-old male patient with hypofibrinogenemia was scheduled to undergo tonsillectomy. Hypofibrinogenemia, defined as low plasma fibrinogen (Fbg) concentration, is a type of congenital Fbg deficiency and is a rare coagulopathy. Perioperative replenishment of Fbg is performed during minor surgeries, aimed at maintaining plasma Fbg concentrations of 50 mg/dL. In this case, failure to replenish Fbg during the postoperative period may have caused the postoperative hemorrhage. Considering the half-life of Fbg (3-4 days), the plasma Fbg concentration should be monitored for >=6 postoperative days, aiming at a target level of 50 mg/dL during the postoperative period.

AB - Kniest dysplasia, or metatropic dysplasia type II, is a rare chondrodysplasia caused by abnormal type II collagen. Clinically, it is characterized by dwarfism, deafness, skeletal derangements, and ocular abnormalities. Mitochondrial diseases produce a spectrum of abnormalities in affected individuals and predominantly impact organs of high energy utilization, including the brain, skeletal muscles, kidneys, and liver. We present the case of a 6-year-old boy with both Kniest dysplasia and underlying mitochondrial disease for examination under anesthesia before cataract surgery. Successful anesthetic management of a patient with Kniest dysplasia and a mitochondrial myopathy is discussed.

AB - There are an estimated 1.4 million transgender adults in the United States, and lack of providers knowledgeable in transgender care is a barrier to health care. Obstetricians and Gynecologists can help increase access in part by becoming competent in gender-affirming hormone therapy. For transgender men, testosterone protocols can be extrapolated from those used for hypogonadal cisgender men. Unfortunately, there are not any high-quality, long-term prospective studies on the effectiveness and safety of different testosterone regimens specifically in transgender men, but the available data suggest that gender-affirming testosterone therapy is safe and effective with proper screening and monitoring.

PMID- 30285976 TI - Recent Trends and the Impact of the Affordable Care Act on Emergency Department Visits and Hospitalizations for Gastrointestinal, Pancreatic, and Liver Diseases. AB - BACKGROUND: The Affordable Care Act (ACA) with Medicaid expansion implemented in 2014, extended health insurance to >20-million previously uninsured individuals. However, it is unclear whether enhanced primary care access with Medicaid expansion decreased emergency department (ED) visits and hospitalizations for gastrointestinal (GI)/pancreatic/liver diseases. METHODS: We evaluated trends in GI/pancreatic/liver diagnosis-specific ED/hospital utilization over a 5-year period leading up to Medicaid expansion and a year following expansion, in California (a state that implemented Medicaid expansion) and compare these with Florida (a state that did not). RESULTS: From 2009 to 2013, GI/pancreatic/liver disease ED visits increased by 15.0% in California and 20.2% in Florida and hospitalizations for these conditions decreased by 2.6% in California and increased by 7.9% in Florida. Following Medicaid expansion, a shift from self pay/uninsured to Medicaid insurance was seen California; in addition, a new decrease in ED visits for nausea/vomiting and GI infections, was evident, without associated change in overall ED/hospital utilization trends. Total hospitalization charges for abdominal pain, nausea/vomiting, constipation, and GI infection diagnoses decreased in California following Medicaid expansion, but increased over the same time-period in Florida. CONCLUSIONS: We observed a striking payer shift for GI/pancreatic/liver disease ED visits/hospitalizations after Medicaid expansion in California, indicating a shift in the reimbursement burden in self-pay/uninsured patients, from patients and hospitals to the government. ED visits and hospitalization charges decreased for some primary care treatable GI diagnoses in California, but not for Florida, suggesting a trend toward lower cost of gastroenterology care, perhaps because of decreased hospital utilization for conditions amenable to outpatient management. PMID- 30285977 TI - Bimodal Hearing or Bilateral Cochlear Implants? Ask the Patient. AB - OBJECTIVE: The objectives of this study were to assess the effectiveness of various measures of speech understanding in distinguishing performance differences between adult bimodal and bilateral cochlear implant (CI) recipients and to provide a preliminary evidence-based tool guiding clinical decisions regarding bilateral CI candidacy. DESIGN: This study used a multiple-baseline, cross-sectional design investigating speech recognition performance for 85 experienced adult CI recipients (49 bimodal, 36 bilateral). Speech recognition was assessed in a standard clinical test environment with a single loudspeaker using the minimum speech test battery for adult CI recipients as well as with an R-SPACE 8-loudspeaker, sound-simulation system. All participants were tested in three listening conditions for each measure including each ear alone as well as in the bilateral/bimodal condition. In addition, we asked each bimodal listener to provide a yes/no answer to the question, "Do you think you need a second CI?" RESULTS: This study yielded three primary findings: (1) there were no significant differences between bimodal and bilateral CI performance or binaural summation on clinical measures of speech recognition, (2) an adaptive speech recognition task in the R-SPACE system revealed significant differences in performance and binaural summation between bimodal and bilateral CI users, with bilateral CI users achieving significantly better performance and greater summation, and (3) the patient's answer to the question, "Do you think you need a second CI?" held high sensitivity (100% hit rate) for identifying likely bilateral CI candidates and moderately high specificity (77% correct rejection rate) for correctly identifying listeners best suited with a bimodal hearing configuration. CONCLUSIONS: Clinics cannot rely on current clinical measures of speech understanding, with a single loudspeaker, to determine bilateral CI candidacy for adult bimodal listeners nor to accurately document bilateral benefit relative to a previous bimodal hearing configuration. Speech recognition in a complex listening environment, such as R-SPACE, is a sensitive and appropriate measure for determining bilateral CI candidacy and also likely for documenting bilateral benefit relative to a previous bimodal configuration. In the absence of an available R-SPACE system, asking the patient whether or not s/he thinks s/he needs a second CI is a highly sensitive measure, which may prove clinically useful. PMID- 30285978 TI - Factors Associated With Successful Setup of a Self-Fitting Hearing Aid and the Need for Personalized Support. AB - OBJECTIVES: Self-fitting hearing aids have the potential to increase the accessibility of hearing health care. The aims of this study were to (1) identify factors that are associated with the ability to successfully set up a pair of commercially available self-fitting hearing aids; 2) identify factors that are associated with the need for knowledgeable, personalized support in performing the self-fitting procedure; and (3) evaluate performance of the individual steps in the self-fitting procedure. DESIGN: Sixty adults with hearing loss between the ages of 51 and 85 took part in the study. Half of the participants were current users of bilateral hearing aids; the other half had no previous hearing aid experience. At the first appointment, participants underwent assessments of health locus of control, hearing aid self-efficacy, cognitive status, problem solving skills, demographic characteristics, and hearing thresholds. At the second appointment, participants followed a set of computer-based instructions accompanied by video clips to self-fit the hearing aids. The self-fitting procedure required participants to customize the physical fit of the hearing aids, insert the hearing aids into the ear, perform self-directed in situ audiometry, and adjust the resultant settings according to their preference. Participants had access to support with the self-fitting procedure from a trained clinical assistant (CA) at all times. RESULTS: Forty-one (68%) of the participants achieved a successful self-fitting. Participants who self-fit successfully were significantly more likely than those who were unsuccessful to have had previous experience with hearing aids and to own a mobile device (when controlling for four potential covariates). Of the 41 successful self-fitters, 15 (37%) performed the procedure independently and 26 (63%) sought support from the CA. The successful self-fitters who sought CA support were more likely than those who self-fit independently to have a health locus of control that is externally oriented toward powerful others. Success rates on the individual steps in the self-fitting procedure were relatively high. No one step was more problematic than any other, nor was there a systematic tendency for particular participants to make more errors than others. Steps that required use of the hearing aids in conjunction with the self-fitting app on the participant's mobile device had the highest rates of support use. CONCLUSIONS: The findings of this study suggest that nonaudiologic factors should be considered when selecting suitable candidates for the self-fitting hearing aids evaluated in this study. Although computer-based instructions and video clips were shown to improve self-fitting skill acquisition relative to past studies in which printed instruction booklets were used, the majority of people are still likely to require access to support from trained personnel while carrying out the self-fitting procedure, especially when this requires the use of an app. PMID- 30285979 TI - Pelvic Floor Disorders After Obstetric Avulsion of the Levator Ani Muscle. AB - OBJECTIVES: With vaginal childbirth, 10% to 30% of women sustain levator ani muscle avulsion. The objective of this study was to estimate the cumulative incidence of prolapse and other pelvic floor disorders (PFDs), comparing vaginally parous women with and without levator avulsion. METHODS: Parous women enrolled in a longitudinal study were assessed annually for PFDs with the Pelvic Organ Prolapse Quantification Examination (for prolapse) and the Epidemiology of Prolapse and Incontinence Questionnaire (for stress incontinence, overactive bladder, and anal incontinence). Three-dimensional transperineal ultrasound was used to identify levator avulsion. Women with and without levator avulsion after vaginal delivery were compared for the cumulative incidence of PFDs. Further analysis also stratified by forceps delivery. RESULTS: At the time of assessment, 453 participants were 6 to 17 years from first delivery (median, 11 years). Levator avulsion was identified in 15% (66/453) and was more common among those who had undergone forceps-assisted delivery (P < 0.001). Levator avulsion was strongly associated with prolapse beyond the hymen (odds ratio, 2.7; 95% confidence interval, 1.3-5.7) and with symptoms of prolapse (odds ratio, 3.0; 95% confidence interval-1.2, 7.3). These associations persisted after controlling for forceps-assisted delivery. In contrast, the odds of stress incontinence, overactive bladder, and anal incontinence were marginally (but not significantly) increased among women with levator avulsion in this cohort. CONCLUSIONS: Obstetric levator avulsion is strongly associated with pelvic organ prolapse. The relationship between levator avulsion and other PFDs may not be significant. PMID- 30285980 TI - Implementation of the Smart Use of Antibiotics Program to Reduce Unnecessary Antibiotic Use in a Neonatal ICU: A Prospective Interrupted Time-Series Study in a Developing Country. AB - OBJECTIVES: We aimed to implement our Smart Use of Antibiotics Program to ensure the proper use of antimicrobials, improve patient care and outcomes, and reduce the risks of adverse effects and antimicrobial resistance. DESIGN: We compared the time periods before (baseline) and after (intervention) the implementation of an antibiotic protocol by performing surveillance and assessments of all antibiotic use during a 29-month interrupted period. SETTING: Level 3-4 neonatal ICU in one referral center. PATIENTS: All 13,540 infants who received antibiotics during their hospital stay from 2015 to 2017. INTERVENTIONS: Prospective audit of targeted antibiotic stewardship program. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the change in total antibiotic days of therapy per 1,000 patient-days between the baseline and intervention periods. The secondary outcomes included readmissions for infection, late-onset sepsis (length of stay), necrotizing enterocolitis, or death in infants at 32 weeks of gestation or younger and the prevalence of multidrug-resistant organism colonization. No differences in safety outcomes were observed between the intervention and baseline periods. Following the implementation of our Smart Use of Antibiotics Program, the total quantity of antibiotics in the intervention phase was significantly decreased from 543 days of therapy per 1,000 patient-days to 380 days of therapy/1,000 patient-days compared with that of baseline (p = 0.0001), which occurred in parallel with a reduction in length of stay from 11.4% during the baseline period to 6.5% during the intervention period (p = 0.01). A reduced multidrug-resistant organism rate was also observed following Smart Use of Antibiotics Program implementation (1.4% vs 1.0%; p = 0.02). The overall readmission rate did not differ between the two periods (1.2% vs 1.1%; p = 0.16). CONCLUSIONS: Smart Use of Antibiotics Program implementation was effective in reducing antibiotic exposure without affecting quality of care. Antibiotic stewardship programs are attainable through tailoring to special stewardship targets even in a developing country. PMID- 30285981 TI - Refinement of the Beliefs About Personal Weight Survey. AB - This study tested the revised Beliefs About Personal Weight Survey-2 (BPWS-2) in 200 African American women, 18 to 40 years of age. Confirmatory factor analysis of a priori hypothesized factors resulted in 5 subscales-weight acceptance (8 items); excess weight acknowledgment (5 items); conventional weight regulation (3 items); circumstantial weight regulation (9 items); and weight concern (10 items). The Cronbach alpha ranged from 0.67 to 0.89. The factors demonstrated patterns of association with eating behavior, body mass index, body image, and psychosocial (depression and perceived stress) variables associated with weight. The BPWS-2 is the first instrument designed to measure beliefs about one's personal weight, thus results make important new contributions to the understanding of weight management. PMID- 30285982 TI - An Emancipatory Approach to Cultural Competency: The Application of Critical Race, Postcolonial, and Intersectionality Theories. AB - Nurses teach, work, and conduct research in an increasingly hostile sociopolitical climate where health inequities persist among marginalized communities. Current approaches to cultural competency do not adequately equip nurses to address these complex factors and risk perpetuating stereotypes and discrimination. A theory-driven emancipatory approach to cultural competency will instead lead to lasting change and uphold the core nursing value of commitment to social justice. This article explicates key tenets of critical race, postcolonial feminist, and intersectionality theories and then applies them, using an emancipatory approach to cultural competency that can reshape nursing education, research, and practice. PMID- 30285983 TI - Dietary Culture: A Concept Analysis. AB - The concept of dietary culture is undefined in the nursing literature. This is problematic due to the significant influence of culture on group eating patterns, which impact cardiovascular health. Cardiovascular disease is the leading cause of death, globally. The purpose of this concept analysis was to define the concept of dietary culture to increase the understanding of the relationship between diet, culture, and cardiovascular health. Walker and Avant's method was employed. This analysis of dietary culture provides insight into the internal structure of the concept for future theory development and promotes the application of the concept to nursing research and practice. PMID- 30285984 TI - Cervical Disk Arthroplasty. AB - Anterior cervical diskectomy and fusion has been and remains the benchmark surgical management of cervical degenerative disk disease. However, an increased use of cervical disk arthroplasty (CDA) has been found in the past few years. The purported benefits of CDA included preserved motion, less adjacent-level degeneration, and less morbidity. Short-term results from randomized control trials clearly showed noninferiority of CDA compared with fusion. With long-term comparison data becoming available, results are equivalent and superior in many metrics compared, favoring CDA. Concerns remain regarding the best way to manage CDA failures. Nonetheless, appropriate patient selection and adherence to strict surgical technique make CDA a viable treatment. PMID- 30285985 TI - Challenges of Medical Care Delivery in Professional Sports: Lessons From Professional Baseball. AB - Team medical management for professional sports teams is a demanding and high risk activity. Every different sport has unique features and the stresses athletes place on themselves, be it from collisions or repetitive stress, result in specific challenges for the medical team and team organization in general. Injuries in professional sports are costly both to the player and organization. The challenges of managing a professional baseball team exemplify these concerns and correlate well with other professional sports. Multiple strategies exist for improvement of medical care in baseball based on observed deficiencies in player evaluation, injury prevention, and injury treatment, which will require prospective evaluation to determine their success. These include draft strategies, individualized motion and strength analyses, customized in-season and off-season training programs for individuals, and standardized treatment protocols for injuries all based on best practices. Best practices are currently poorly defined in all of these areas. PMID- 30285986 TI - Potential Economic Benefits of Limited Clinical and Radiographic Follow-up After Plate Fixation of Midshaft Clavicle Fractures. AB - INTRODUCTION: The role of routine clinical and radiographic follow-up after clavicle fractures are healed was evaluated. METHODS: A retrospective study performed in two level-1 trauma centers included 246 adults with healed clavicle fractures treated surgically between 2000 and 2013 and at least 24-month follow up. Based on radiographs, changes in fracture alignment or implant position from union to final follow-up were documented. The average reimbursement for a follow up clinical visit and a clavicle radiograph was estimated. RESULTS: Mean time to union and mean time of follow-up were of 4.8 and 31.4 months, respectively. No changes in implant position or fracture alignment occurred after the fracture had healed. The amount reimbursed to our institution for two clinical visits and two clavicle radiographs was approximately $300 to $540. CONCLUSION: Once clavicle fractures are healed, further radiographic imaging does not provide any notable information. Limiting routine follow-up is safe and could be cost-effective for the healthcare system. LEVEL OF EVIDENCE: Level-III retrospective cohort study. PMID- 30285987 TI - Orthopaedic Resident Use of an Electronic Medical Record Template Does Not Improve Documentattion for Pediatric Supracondylar Humerus Fractures. AB - INTRODUCTION: Pediatric supracondylar humerus fractures are associated with a high incidence of nerve injury. Therefore, it is imperative that documentation be complete and accurate. This investigation compares orthopaedic resident history and physical (H&P) documentation of pediatric supracondylar fractures for completeness and accuracy with and without the use of an electronic medical record template. METHODS: The electronic medical record H&P documentation of 119 supracondylar humerus fractures surgically treated at a single pediatric institution was retrospectively reviewed. Templated and nontemplated groups were compared for documentation completeness and accuracy. Definitive diagnosis of a nerve palsy was made by a supervising orthopaedic attending surgeon. RESULTS: Forty-two cases had a templated H&P and 77 did not. The H&P documentation in the templated group was markedly more complete than that in the nontemplated group. However, the accuracy of the H&P documentation to identify nerve palsy was not statistically different between the two groups. Overall, the voluntary use of the orthopaedic template declined over time. CONCLUSION: Resident use of an orthopaedic template for documenting the H&P of pediatric supracondylar humerus fractures compared with nontemplated notes resulted in more complete documentation but only comparable accuracy. LEVEL OF EVIDENCE: III. PMID- 30285988 TI - Inhospital Complications of Patients With Neuromuscular Disorders Undergoing Total Joint Arthroplasty. AB - INTRODUCTION: Orthopaedic surgeons are wary of patients with neuromuscular (NM) diseases as a result of perceived poor outcomes and lack of data regarding complication risks. We determined the prevalence of patients with NM disease undergoing total joint arthroplasty (TJA) and characterized its relationship with in-hospital complications, prolonged length of stay, and total charges. METHODS: Data from the Nationwide Inpatient Sample from 2005 to 2014 was used for this retrospective cohort study to identify 8,028,435 discharges with total joint arthroplasty. International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to identify 91,420 patients who had discharge diagnoses for any of the NM disorders of interest: Parkinson disease, multiple sclerosis, cerebral palsy, cerebrovascular disease resulting in lower extremity paralysis, myotonic dystrophy, myasthenia gravis, myositis (dermatomyositis, polymyositis, and inclusion-body myositis), spinal muscular atrophy type III, poliomyelitis, spinal cord injury, and amyotrophic lateral sclerosis. Logistic regression was used to estimate the association between NM disease and perioperative outcomes, including inpatient adverse events, length of stay, mortality, and hospital charges adjusted for demographic, hospital, and clinical characteristics. RESULTS: NM patients undergoing TJA had increased odds of total surgical complications (odds ratio [OR] = 1.21; 95% confidence interval [CI], 1.17 to 1.25; P < 0.0001), medical complications (OR = 1.41; 95% CI, 1.36 to 1.46; P < 0.0001), and overall complications (OR = 1.32; 95% CI, 1.28 to 1.36; P < 0.0001) compared with non-NM patients. Specifically, NM patients had increased odds of prosthetic complications (OR = 1.09; 95% CI, 0.84 to 1.42; P = 0.003), wound dehiscence (OR = 5.00; 95% CI, 1.57 to 15.94; P = 0.0002), acute postoperative anemia (OR = 1.20; 95% CI, 1.16 to 1.24; P < 0.0001), altered mental status (OR = 2.59; 95% CI, 2.24 to 2.99; P < 0.0001), urinary tract infection (OR = 1.45; 95% CI, 1.34 to 1.56; P < 0.0001), and deep vein thrombosis (OR = 1.27; 95% CI, 1.02 to 1.58; P = 0.021). No difference of in-hospital mortality was observed (P = 0.155). DISCUSSION: Because more patients with NM disease become candidates of TJA, a team of neurologists, anesthesiologists, therapists, and orthopaedic surgeon is required to anticipate, prevent, and manage potential complications identified in this study. LEVEL OF EVIDENCE: Level III, retrospective cohort study. PMID- 30285989 TI - Free Latissimus Dorsi Myocutaneous Flap in a 6-Month-Old Child for Reconstruction of a Temporal Fossa Defect After Teratoma Resection. AB - Although free flap reconstruction has already gained widespread acceptance in pediatric patients, little is known about the outcome of free tissue transfer in head and neck reconstruction in pediatric patients. We present a case of a 6 month-old boy with a large volume deficit in the right temporal fossa after resection of a teratoma. This led to a large volume deficit with widely undermined skin margins. Therefore, we provided volume augmentation by microsurgical free latissimus dorsi myocutaneous flap transplantation. Intraoperative use of laser-assisted indocyanine green angiography indicated excellent flap perfusion. Postoperative magnetic resonance imaging showed adequate flap perfusion with no signs of flap necrosis. To our best knowledge, this case presents the youngest patient who underwent free flap transplantation in the head and neck region. Our case demonstrates that microvascular surgery can play an important role in particular cases in pediatric oncology, even in very young patients. PMID- 30285990 TI - Unfiltered Nanofat Injections Rejuvenate Postburn Scars of Face. AB - The aim of this study was to compare the quality of postburn facial scars before and after injection of unfiltered nanofat. The study was performed in the Plastic Surgery Department of Mayo Hospital, Lahore, Pakistan, from January 2015 to December 2016. Forty-eight patients with postburn facial scars were included; age range was 4 to 32 years with Fitzpatrick skin types between 3 and 4. Patients with hypertrophic scars, contractures, or keloids were excluded. Scars were assessed by a senior plastic surgeon and the patient on the POSAS (Patient Observer Scar Assessment Scale). Fat was harvested from the abdomen and/or thighs with a 3-mm multiport liposuction cannula (containing several sharp side holes of 1 mm) using Coleman technique. The harvested fat was emulsified and transferred into 1-mL Luer-Lock syringes for injection into the subdermal or intradermal plane. Final follow-up was scheduled at 6 months, and scar was rated by the patient and the same surgeon on the POSAS. Preoperative and postoperative scar scores were compared, and P values were calculated. Results indicated that after nanofat grafting, there was a statistically significant improvement in scar quality. The most significant improvements on the observer scale were seen in pigmentation and pliability (P < 0.0001). Thickness and relief were the least improved variables (P = of 0.785 and 0.99, respectively). ImageJ scanning also showed pigmentation change (P = 0.076). A statistically significant improvement was seen in all parameters of the patient section of the POSAS (P < 0.0001). In conclusion, unfiltered nanofat grafting seems to be a promising and effective therapeutic approach in postburn facial scars, showing significant improvement in scar quality. The trial was registered on www.clinicaltrials.gov with following ID NCT03352297. PMID- 30285991 TI - Temporary Ectopic Implantation of an Amputated Leg Using the Distal Runoff Vessel of the Anterolateral Thigh Flap Followed by Subsequent Prefabricated Chimeric Replantation. AB - AIM: Infrapopliteal replantation is indicated in selected patients. When the patient is hemodynamically unstable or the amputation site is severely contaminated, temporary ectopic implantation of the amputated limb is an option. To the best of our knowledge, this is the first case report using the distal runoff vessel of the anterolateral thigh flap for temporary ectopic implantation of an amputated leg followed by replantation with the prefabricated anterolateral thigh flap. PATIENT AND METHODS: A 28-year-old male driver had left leg avulsion amputation after a car accident. Because of concerns about the high-energy trauma mechanism and extensive trauma zone, temporary ectopic implantation was planned to avoid a lengthy replantation procedure and to enable future replantation. The amputated leg was implanted to the thigh using the distal runoff vessel of the descending branch of the lateral circumflex femoral system in the preservation of proximal cutaneous perforator. When the patient became hemodynamically stable and the amputated stump was relatively clean and healthy, we replanted the amputated leg with the prefabricated anterolateral thigh flap on day 7. RESULTS: The replanted leg and anterolateral thigh flap survived well after the procedure. At the 15-month follow-up, the patient could walk independently. There was no need for custom-made shoes because there was no obvious leg length discrepancy and the flap was not bulky. CONCLUSIONS: We believe that the distal runoff vessel of the descending branch of the lateral circumflex femoral system can not only serve as a recipient site for temporary ectopic implantation but also enable the harvest of a prefabricated anterolateral thigh flap with the amputated part at the replantation stage. This prefabricated tissue containing the anterolateral thigh flap and the amputated part needs only 1 set of vascular anastomosis to accomplish replantation and simultaneous revascularization of the anterolateral thigh flap. Most importantly, this ectopically prefabricated chimeric tissue minimizes the need for extensive bone shortening after radial debridement by providing sufficient soft tissue coverage at the replantation stage. PMID- 30285992 TI - Alteration of Sciatic Nerve Histology and Electrical Function After Compression and After Neurolysis in a Diabetic Rat Model. AB - BACKGROUND: Diabetic rats are more sensitive to nerve entrapment. This study was conducted to evaluate nerve function and histological changes in diabetic rats after nerve compression and subsequent decompression. METHODS: A total of 35 Wistar rats were included. The experimental group was divided into diabetic sciatic nerve compression group (DSNC, n = 5) and diabetic sciatic nerve decompression group (DSND, n = 20). The DSNC model was created by wrapping a silicone tube circumferentially around the nerve for 4 weeks, and then the DSND group accepted nerve decompression and was followed up to 12 weeks. The DSND group was equally divided into DSND 3 weeks (DSND3), 6 weeks (DSND6), 9 weeks (DSND9), and 12 weeks (DSND12) groups. Five rats were taken as normoglycemic control group (CR, n = 5), and another 5 rats as diabetic control group (DM, n = 5). The mechanical hyperalgesia of rats was detected by Semmes-Weinstein nylon monofilaments (SWMs) and by motor nerve conduction velocity (MNCV). These 2 physiological indicators and histology of sciatic nerves were compared among different groups. RESULTS: The SWM measurements improved toward normal values after decompression. The SWM value was significantly lower (more normal) in the DSNC groups than in the DSND group (P < 0.05). The MNCV was 53.7 +/- 0.8 m/s in the CR group, whereas it was 28.4 +/- 1.0 m/s in the DSNC group (P < 0.001). Six weeks after decompression, the MNCV was significantly faster than that in the DSNC group (P < 0.001). Histological examination demonstrated chronic nerve compression, which responded toward normal after decompression, but with degree of myelination never recovering to normal. CONCLUSIONS: Chronic compression of the diabetic sciatic nerve has measureable negative effects on sciatic nerve motor nerve function, associated with a decline of touch/pressure threshold and degeneration of myelin sheath and axon. Nerve decompression surgery can reverse these effects and partially restore nerve function. PMID- 30285993 TI - A New Method for Double-Eyelid Blepharoplasty Using Orbital Septum. AB - BACKGROUND: This article presents a new method using orbital septum for double eyelid blepharoplasty. METHODS: During double-eyelid blepharoplasty, we incised the orbital septum horizontally. Using the attachment site of the levator aponeurosis as a pedicle, the lower part of the dissected orbital septum was turned downward and then sutured to the upper border of the lower orbicularis oculi muscle and posterior pretarsal fascia. We evaluated the efficacy of this double-eyelid surgical procedure in patients undergoing the procedure from December 2015 to October 2017. RESULTS: We included 462 eyes of 231 patients in the final analysis. Sutures were removed 7 days after surgery. All double-eyelid creases were well formed, and the eyelids closed well. Six-month follow-up results revealed that the double-eyelid shape was natural looking, and no patients experienced upper eyelid retraction or incomplete eye closure. Notched scars did not occur, and patient satisfaction was achieved in all cases. Two hundred eleven patients were fully satisfied with the surgical results, and 20 were basically satisfied with the surgical results. CONCLUSIONS: Using the orbital septum is a good approach for double-eyelid blepharoplasty. PMID- 30285994 TI - Occlusion, Occlusion, Where Art Thou? PMID- 30285996 TI - "Atrophic Kidney"-like Lesion: Clinicopathologic Series of 8 Cases Supporting a Benign Entity Distinct From Thyroid-like Follicular Carcinoma. AB - Renal mass lesions with a follicular architecture resembling atrophic kidney have been described, but their distinction from thyroid-like follicular carcinoma of the kidney remains controversial. We collected 8 cases of this purported "atrophic kidney"-like lesion to fully describe their clinical and histologic spectrum, their possible etiology, and to discuss their distinction from other renal neoplasms. Eight total cases were identified with patient ages ranging from 9 to 48 years (mean: 29 y; median: 28.5 y). Four patients were female and 4 were male. The tumors were unifocal and size ranged from 1.6 to 4.9 cm (mean: 3.4 cm; median: 3.4 cm). All 8 tumors had a remarkably similar histology. Each was enveloped by a smooth muscle rich capsule and had an overall low power "follicular" architecture. The luminal spaces of the "follicles" (or cysts) contained eosinophilic secretions and the lining epithelium was often flattened and atrophic, but some had more rounded cells with a distinctive hobnail arrangement. Many cysts contained discohesive round cells floating within the eosinophilic material, and some contained small intraluminal tufts with features of markedly atrophic glomeruli. Periodic acid-Schiff stains highlighted basement membrane material extending into these glomerular-like tufts, and some contained small distinct capillaries surrounded by endothelial cells, interspersed mesangial-like cells, and rare surrounding podocyte-like cells, providing additional evidence for glomerulocystic structures. Scattered calcifications were present within cysts (or within cyst walls) in varying numbers and were characterized by 2 types: psammoma body-like or more amorphous deposits. The tissue between cystic glomeruli contained predominantly small atrophic tubular structures, but collagenized stroma and smaller collapsed glomeruli were also present. The 2 tumors from the oldest 2 patients (48 and 39 y) had a more striking degree of stromal hyalinization. Immunohistochemically, the cyst lining cells had a predominant WT-positive/PAX-8 negative/CK7-negative phenotype, while tubules were typically WT-1 negative/PAX-8 positive/CK7-positive. Upon comparison to a control group of 10 kidneys containing incidental non-mass-forming glomerulocystic change, the morphologic features and immunophenotype were identical. To date, no patient has had any recurrence or aggressive clinical behavior based on follow status in 7 of 8 cases (follow-up range: 9 to 168 mo; median: 24 mo; mean: 40 mo). In summary, we describe the clinicopathologic features of 8 unique, benign "atrophic kidney"-like lesions that may simply represent a non-neoplastic form of organizing tubular atrophy and glomerulocystic change, and emphasize their distinction from thyroid-like follicular carcinoma of the kidney. PMID- 30285995 TI - VSTM2A Overexpression Is a Sensitive and Specific Biomarker for Mucinous Tubular and Spindle Cell Carcinoma (MTSCC) of the Kidney. AB - Our recent study revealed recurrent chromosomal losses and somatic mutations of genes in the Hippo pathway in mucinous tubular and spindle cell carcinoma (MTSCC). Here, we performed an integrative analysis of 907 renal cell carcinoma (RCC) samples (combined from The Cancer Genome Atlas and in-house studies) and the Knepper data set of microdissected rat nephrons. We identified VSTM2A and IRX5 as novel cancer-specific and lineage-specific biomarkers in MTSCC. We then assessed their expression by RNA in situ hybridization (ISH) in 113 tumors, including 33 MTSCC, 40 type 1 papillary RCC, 8 type 2 papillary RCC, 2 unclassified RCC, 15 clear cell RCC, and 15 chromophobe RCC. Sensitivity and specificity were calculated as the area under the receiver operating characteristics curve (AUC). All MTSCC tumors demonstrated moderate to high expression of VSTM2A (mean ISH score=255). VSTM2A gene expression assessed by RNA sequencing strongly correlated with VSTM2A ISH score (r=0.81, P=0.00016). The majority of non-MTSCC tumors demonstrated negative or low expression of VSTM2A. IRX5, nominated as a lineage-specific biomarker, showed moderate to high expression in MTSCC tumors (mean ISH score=140). IRX5 gene expression assessed by RNA sequencing strongly correlated with IRX5 ISH score (r=0.69, P=0.00291). VSTM2A (AUC: 99.2%) demonstrated better diagnostic efficacy than IRX5 (AUC: 87.5%), and may thus serve as a potential diagnostic marker to distinguish tumors with overlapping histology. Furthermore, our results suggest MTSCC displays an overlapping phenotypic expression pattern with the loop of Henle region of normal nephrons. PMID- 30285997 TI - Adamantinoma-like Ewing Sarcoma of the Salivary Glands: A Newly Recognized Mimicker of Basaloid Salivary Carcinomas. AB - Adamantinoma-like Ewing sarcoma (ALES) is a rare tumor that demonstrates the EWSR1-FLI1 translocation characteristic of Ewing sarcoma despite overt epithelial differentiation including diffuse expression of cytokeratins and p40. Most cases of ALES described to date have occurred in the head and neck where they can mimic a wide range of small round blue cell tumors. Because distinguishing ALES from basaloid salivary gland carcinomas can be particularly difficult, we analyzed a series of 10 ALESs that occurred in the salivary glands with the aim of identifying features that allow for better recognition of this entity. The salivary ALESs included 8 parotid gland and 2 submandibular gland tumors in patients ranging from 32 to 77 years (mean: 52 y). Nine were initially misclassified as various epithelial neoplasms. Although these tumors displayed the basaloid cytology, rosette formation, infiltrative growth, and nuclear monotony characteristic of ALES, peripheral palisading and overt keratinization were relatively rare in this site. Salivary ALESs not only displayed positivity for AE1/AE3, p40, and CD99, but also demonstrated a higher proportion of synaptophysin reactivity than has been reported for nonsalivary ALESs. These morphologic and immunohistochemical findings make ALES susceptible to misclassification as various other tumors including basal cell adenocarcinoma, adenoid cystic carcinoma, squamous cell carcinoma, NUT carcinoma, large cell neuroendocrine carcinoma and myoepithelial carcinoma. Nevertheless, monotonous cytology despite highly infiltrative growth and concomitant positivity for p40 and synaptophysin can provide important clues for consideration of ALES, and identification of the defining EWSR1-FLI1 translocations can confirm the diagnosis. PMID- 30285998 TI - Eleven Years of Clozapine Experience in Autism Spectrum Disorder: Efficacy and Tolerance. AB - BACKGROUND: Autism spectrum disorders (ASDs) are neurodevelopmental disorders that comprise wide graduated clinical expressions but similar core symptoms (repetitive, stereotyped behavior, and social communication disabilities). Many patients with ASD have disruptive behaviors like aggressiveness, temper tantrums, or self-injury that interfere with their socializations, their learning abilities, and their quality of life. These behaviors represent a common target for pharmacology. Beherec et al (J Clin Psychopharmacol. 2011;31:341-344) (first cohort), showed the efficacy of clozapine on disruptive behaviors in 6 patients with autism who were older than 16 years. The aim of this study was to assess the efficacy and tolerance of clozapine in a new cohort and the long-term effect in our first cohort. PROCEDURES: Concerning the replication study, we conducted a retrospective study of the changes of aggressive behaviors for all patients with ASD who were treated with clozapine from 2011 to 2017. Disruptive behaviors were monitored from 1 to 6 months before and after the initiation of the clozapine. RESULTS: All the patients of the first cohort were still on clozapine after an average of 11 + 2.6 years, with the same efficacy and no serious adverse effect was noted. For the replication study, 13 patients were included. Clozapine resulted in a significant decrease in the number of the days with aggression (65.2% + 32.6%). Once again, no serious adverse effect was notified. All the patients had a better quality of life. CONCLUSIONS: Our study confirms that clozapine could be an efficacious and well-tolerated treatment for ASD patients with disruptive behaviors who do not respond to other antipsychotics on the long term.

PMID- 30286001 TI - Anatomy of the Superficial Venous Structures of the Neck: A Cadaveric Study to Guide Superficial Injections. AB - BACKGROUND: Minimally invasive aesthetic procedures of the neck are becoming more popular. However, anatomical studies on the venous structures of the neck in relation to these procedures are lacking. OBJECTIVE: The aims of this study were to identify the locations and communication patterns of the anterior jugular vein and external jugular vein (AJV and EJV) and the communicating vein (CV) based on superficial anatomical landmarks and to determine dangerous areas for dermal filler injections into the neck. MATERIALS AND METHODS: Thirty sides of the neck from Korean adult cadavers were dissected for this study. RESULTS: Four anatomical variants were identified. In Type Ia, the CV ran along the anterior border of the sternocleidomastoid muscle (SCM) (33.4%); in Type Ib, a single vein was observed connecting the CV and the EJV at the level of laryngeal prominence (23.3%); in Type Ic, the CV proceeded separately from the medial side of the anterior border of the SCM (13.3%); and in Type II, the CV was absent while the EJV and AJV were observed (30%). CONCLUSION: Given the 4 anatomical variants identified in this study, the authors recommend exerting caution when performing dermal filler injections approximately 10, 30, and 60 mm lateral to the midsagittal line to avoid iatrogenic side effects.

PMID- 30286003 TI - Predicting the Depth of the Lumbar Plexus in Pediatric Patients: A Retrospective Magnetic Resonance Imaging Study. AB - BACKGROUND: The lumbar plexus (LP) block is commonly used for analgesia for lower extremities. If the depth of the LP (LPD) can be predicted, the performance time and procedure-related complications could be reduced. METHODS: Three hundred sixty-one magnetic resonance images of pediatric patients (<18 years of age) were analyzed. Simple linear regression and multiple linear regression analyses were performed to predict the LPD using patient age, weight, height, and the distance between the midline and posterior superior iliac spine (midline-PSIS). The ratio of the distance between the midline and the most lateral aspect of the LP (midline-LP) to midline-PSIS (midline-LP/midline-PSIS ratio) was calculated to suggest a needle insertion point at the L4/L5 intervertebral level. The presence of the kidney at the L4 level and the L4/L5 intervertebral level was determined. RESULTS: The LPD at the L4/L5 intervertebral levels was predicted using the equation LPD = 0.844 * weight (kg) + 25.8 (mm) in pediatric patients <18 years of age (r = 0.791; 95% confidence interval [CI] of r, 0.753-0.829). The overall midline-LP/midline-PSIS ratio was 0.87 (95% CI, 0.86-0.89), and the ratio was higher in neonates and infants (0.98 [95% CI, 0.95-1.02]) than in the other age groups. The presence of the lower kidney pole at the L4 level was common in pediatric patients (43.7% of neonates and infants and 13.7% of toddlers and preschool-aged children). The lower kidney pole was observed at the L4/L5 level in 6 patients (1.7%). CONCLUSIONS: When LP block is performed in pediatric patients, the LPD and risk of renal injury should be considered for successful and safe analgesic block.

AB - BACKGROUND: There are limited data about how to choose the correct size of a double-lumen tube (DLT). It is especially difficult to select an appropriate DLT for Asian women because of their small stature. The primary aim of this study was to compare the overall accuracy of the DLT selected based on the combination of transverse diameter of cricoid ring and the equivalent diameter of the left main bronchus (ED-LMB) with that based on the ED-LMB alone for Asian women. METHODS: In this study, 80 consecutive and blinded female patients were assigned randomly to 2 groups. The overall accuracy of the selection of DLT was compared between the Combined group and LMB group. The accuracy of the selection of tracheal segment and bronchial segment was also compared between the 2 groups. The postoperative hoarseness and sore throat were investigated by blinded assessors. RESULTS: The overall accuracy of selection of the DLTs was higher in the Combined group than that in the LMB group (87.5% vs 60.0%; P = .010). The accuracy of selection of tracheal segment was also higher in the Combined group (92.5% vs 67.5%; P = .010). The accuracy of selection of bronchial segment was similar between the groups (95.0 % vs 86.1%; P = .246). The severity of sore throat was higher in the LMB group at 24 hours after the operation (P = .001). CONCLUSIONS: The correct size of DLT for Asian women should be selected based on the combination of transverse diameter of cricoid ring and the ED-LMB. PMID- 30286005 TI - Regional Anesthesia and Readmission Rates After Total Knee Arthroplasty. AB - BACKGROUND: Total knee arthroplasty is a commonly performed procedure and an important contributor to national health care spending. Reducing the incidence of readmission could have important consequences for patient well-being and relevant financial implications. Whether regional anesthesia techniques are associated with decreased readmission rates and costs among privately insured patients remains unknown. METHODS: Using administrative claims data, we identified 138,362 privately insured patients 18-64 years of age who underwent total knee arthroplasty between 2002 and 2013. We then examined whether the use of a nerve block was associated with decreases in readmission rates and related costs during the 90 days after discharge. Our analyses were adjusted for potential confounding variables including medical comorbidities and previous use of opioids and other medications. RESULTS: After adjusting for patient demographics, comorbidities, and preoperative medication use, the adjusted 90-day readmission rate was 1.8% (95% confidence interval [CI], 1.1-2.4) among patients who did not receive a block compared to 1.7% (95% CI, 1.1-2.4) among patients who did (odds ratio, 0.99; 95% CI, 0.91-1.09; P = .85). The adjusted readmission-related postoperative cost for patients who did not receive a block was $561 (95% CI, 502-619) and $574 (95% CI, 508-639) for patients who did (difference, $13; 95% CI, -75 to 102; P = .74). This lack of statistically significant differences held for subgroup and sensitivity analyses. CONCLUSIONS: Nerve blocks were not associated with improved measures of long-term postoperative resource use in this younger, privately insured study population.

AB - Admixtures of propofol-ketamine, propofol-ketamine-fentanyl, and propofol ketamine-remifentanil were subjected to various clinically relevant conditions to study their chemical stability. A novel high-performance liquid chromatography mass spectrometry method revealed no degradation of any compound by incubation at 37 degrees C, constant mixing, or table-top storage for 6- and 24-hour time periods, except variable recovery of both propofol and fentanyl in the admixtures of propofol-ketamine-fentanyl suggesting possible degradation. PMID- 30286007 TI - Resident Competency and Proficiency in Combined Spinal-Epidural Catheter Placement Is Improved Using a Computer-Enhanced Visual Learning Program: A Randomized Controlled Trial. AB - BACKGROUND: Physician educators must balance the need for resident procedural education with clinical time pressures as well as patient safety and comfort. Alternative educational strategies, including e-learning tools, may be beneficial to orient novice learners to new procedures and speed proficiency. We created an e-learning tool (computer-enhanced visual learning [CEVL] neuraxial) to enhance trainee proficiency in combined spinal-epidural catheter placement in obstetric patients and performed a randomized controlled 2-center trial to test the hypothesis that use of the tool improved the initial procedure performed by the anesthesiology residents. METHODS: Anesthesiology residents completing their first obstetric anesthesiology rotation were randomized to receive online access to the neuraxial module (CEVL group) or no access (control) 2 weeks before the rotation. On the first day of the rotation, residents completed a neuraxial procedure self-confidence scale and an open-ended medical knowledge test. Blinded raters observed residents performing combined spinal-epidural catheter techniques in laboring parturients using a procedural checklist (0-49 pts); the time required to perform the procedure was recorded. The primary outcome was the duration of the procedure. RESULTS: The CEVL group had significantly shorter mean (+/-standard deviation) procedure time compared to the control group 22.5 +/- 4.9 vs 39.5 +/- 7.1 minutes (P < .001) and had higher scores on the overall performance checklist 36.4 +/- 6.6 vs 28.8 +/- 7.1 (P = .012). The intervention group also had higher scores on the open-ended medical knowledge test (27.83 +/- 3.07 vs 22.25 +/- 4.67; P = .002), but self-confidence scores were not different between groups (P = .64). CONCLUSIONS: CEVL neuraxial is a novel prerotation teaching tool that may enhance the traditional initial teaching of combined spinal-epidural procedures in obstetric anesthesiology. Future research should examine whether the use of web-based learning tools impacts long-term provider performance or patient outcomes. PMID- 30286008 TI - Red Blood Cell Transfusion in Pediatric Orthotopic Liver Transplantation: What a Difference a Few Decades Make. AB - BACKGROUND: Liver transplantation in children is often associated with coagulopathy and significant blood loss. Available data are limited. In this observational retrospective study, we assessed transfusion practices in pediatric patients undergoing liver transplantation at a single institution over the course of 9 years. METHODS: Data were retrospectively collected from patient medical records at the Children's Hospital of Pittsburgh of University of Pittsburgh Medical Center. All patients who underwent liver transplantation from January 2008 to June 2017 were included. Primary and secondary outcomes were volume of red blood cells (RBCs) transfused and mortality, respectively. RESULTS: From January 2008 to June 2017, there were 278 liver transplants in 271 patients. The number of primary transplants were 259, second retransplants 15, and third retransplants 4. Average age at transplantation was 6.9 years. Biliary atresia, maple syrup urine disease, urea cycle defect, and liver tumor were the leading indications accounting for 66 (23.7%), 45 (16.2%), 24 (8.6%), and 23 (8.3%) of transplants, respectively. Seventy-six cases (27.3%) did not require RBC transfusions. Among those transfused, 181 (89.6%) of the cases required <1 blood volume (BV). The median BV transfused among all cases was 0.21 (range, 0-9; Q1, 0; Q3, 0.45). There is a trend toward higher volume transfusions among infants (median, 0.46 BV) compared to children >12 months of age (0.12 BV). By diagnosis, the group requiring the highest median volume transfusion was patients with total parenteral nutrition-related liver failure (3.41 BV) followed by patients undergoing repeat transplants (0.6 BV). Comparison of primary versus repeat transplants shows a trend toward higher volume transfusions in third transplants (median, 2.71 BV), compared to second transplants (0.43 BV) and primary transplants (0.18 BV). Four of 271 patients (1.5%) died during admission involving liver transplantation. Nine of 271 patients (3.3%) died subsequently. Total mortality was 4.8%. CONCLUSIONS: In contrast to historically reported trends, evaluation of current transfusion practices reveals that most patients undergoing liver transplantation receive <1 BV of packed RBCs. More than 1 in 4 transplantations require no transfusion at all. Risk factors for greater transfusion need include younger age, total parenteral nutrition-related liver failure, and repeat transplantation. PMID- 30286009 TI - Real-Time Measurement of Xenon Concentration in a Binary Gas Mixture Using a Modified Ultrasonic Time-of-Flight Anesthesia Gas Flowmeter: A Technical Feasibility Study. AB - BACKGROUND: Xenon (Xe) is an anesthetic gas licensed for use in some countries. Fractional concentrations (%) of gases in a Xe:oxygen (O2) mixture are typically measured using a thermal conductivity meter and fuel cell, respectively. Speed of sound in such a binary gas mixture is related to fractional concentration, temperature, pressure, and molar masses of the component gases. We therefore performed a study to assess the feasibility of developing a novel single sterilizable device that uses ultrasound time-of-flight to measure both real-time flowmetry and fractional gas concentration of Xe in O2. METHODS: For the purposes of the feasibility study, we adapted an ultrasonic time-of-flight flowmeter from a conventional anesthetic machine to additionally measure real-time fractional concentration of Xe in O2. A total of 5095 readings of Xe % were taken in the range 5%-95%, and compared with simultaneous measurements from the gold standard of a commercially available thermal conductivity Xe analyzer. RESULTS: Ultrasonic measurements of Xe (%) showed agreement with thermal conductivity meter measurements, but there was marked discontinuity in the middle of the measurement range. Bland-Altman analysis (95% confidence interval in parentheses) yielded: mean difference (bias) 3.1% (2.9%-3.2%); lower 95% limit of agreement -4.6% ( 4.8% to -4.4%); and upper 95% limit of agreement 10.8% (10.5%-11.0%). CONCLUSIONS: The adapted ultrasonic flowmeter estimated Xe (%), but the level of accuracy is insufficient for clinical use. With further work, it may be possible to develop a device to perform both flowmetry and binary gas concentration measurement to a clinically acceptable degree of accuracy. PMID- 30286010 TI - Prior History of Pancreatitis Accelerates the Development of Pancreatic Adenocarcinoma. AB - OBJECTIVES: Presentation of pancreatic adenocarcinoma (PC) as acute pancreatitis (AP), association of chronic pancreatitis (CP) with PC, and role of inflammation in PC carcinogenesis are well recognized. We hypothesized that inflammatory changes associated with remote history of AP (>=2 years before PC diagnosis) would result in earlier age of PC diagnosis. METHODS: We evaluated PC patients prospectively enrolled in the Pancreatic Adenocarcinoma Gene Environment Risk (PAGER) study at the University of Pittsburgh for history of pancreatitis and reviewed relevant medical records and imaging studies. Univariate and multivariable linear regression analyses evaluated the relationship between PC and remote history of AP. RESULTS: Among 790 patients with histologically confirmed PC, 114 (14.4%) had a history of pancreatitis (AP within 2 years of PC diagnosis in 69 [8.7%], remote history of AP in 28 [3.5%], CP in 4 [0.5%], and unknown duration of pancreatitis in 13 [1.6%]). After controlling for age, sex, body mass index, smoking, alcohol history, and diabetic status at diagnosis, patients with a remote history of AP were diagnosed on average 4.7 years earlier with PC when compared with PC patients without history of AP (P < 0.035). CONCLUSIONS: Remote history of AP may accelerate carcinogenesis in PC. PMID- 30286011 TI - Prognostic Impact of Portal System Invasion in Pancreatic Cancer Based on Image Classification. AB - OBJECTIVES: This study aimed to clarify the correlation between image classification and the pathological degree of portal system invasion (PSI) and to evaluate the prognostic impact of PSI in pancreatic cancer (PC). METHODS: Pancreatic cancer patients with surgical resections (head, n = 244; body and tail, n = 80) were enrolled in this study. RESULTS: Based on imaging findings, portal vein (PV) invasion was classified as type A (absent), B (unilateral narrowing), C (bilateral narrowing), or D (stenosis or obstruction with collaterals). Splenic vein (SPV) invasion was classified as type alpha (absent), beta (stenosis), or gamma (obstruction). The pathological grade of venous invasion was classified as grade 0 (no invasion), 1 (tunica adventitia), 2 (tunica media), or 3 (tunica intima). In PV and SPV invasions, image classification and pathological grade showed significant correlation (PV: rho = 0.696; SPV: rho = 0.681). Patients with PV invasion deeper than type B exhibited significantly poorer survival than type A (P < 0.0001). In contrast, there was no difference in survival among types alpha, beta, and gamma. CONCLUSIONS: Image classification was correlated with the pathological grade of PSI in PC. Although not applicable for SPV invasion, image classification of PV invasion is a robust indicator for PC prognosis. PMID- 30286012 TI - Evaluation of Pancreatic Fibrosis With Acoustic Radiation Force Impulse Imaging and Automated Quantification of Pancreatic Tissue Components. AB - OBJECTIVES: The aim of this study was to determine whether computer-assisted digital analysis and acoustic radiation force impulse (ARFI) imaging were useful for assessing pancreatic fibrosis, and if ARFI imaging predicted postoperative pancreatic fistula (POPF). METHODS: Seventy-eight patients scheduled to undergo pancreatic resection were enrolled. Shear wave velocity (SWV) at the pancreatic neck was measured preoperatively using ARFI imaging. Pancreatic tissue components on a whole slide image were quantified using an automatic image processing software. The relationship between SWV, fibrotic tissue content, and POPF incidence and clinical severity was analyzed. RESULTS: The median collagen fiber, fatty tissue, and acinar cell contents were 11.6%, 8.5%, and 61.3%, respectively. Unlike fatty tissue, collagen fiber content and acinar cells were correlated with SWV (rho = 0.440, P < 0.001 and rho = -0.428, P < 0.001, respectively). Although collagen fiber content and SWV were associated with the overall incidence of POPF (P = 0.004 and 0.001, respectively), collagen fiber content and SWV had no statistical correlation with clinically relevant POPF (P = 0.268 and 0.052, respectively). CONCLUSIONS: We objectively quantified the pancreatic tissue components using an automatic image processing software. Shear wave velocity was significantly related to collagen fiber content and suggests that ARFI imaging can be useful for evaluating pancreatic fibrosis. PMID- 30286013 TI - Understanding Pancreatic Diseases Using Animated Pancreas Patient: Informing Patients for Better Health Outcomes With Visual Formats of Learning. AB - OBJECTIVES: The aim of this study was to evaluate the impact of Animated Pancreas Patient (APP) educational modules (APP website and YouTube) on pancreas education, awareness, and health outcomes. METHODS: This was a retrospective study of APP metrics data from September 2013 to October 2017. We evaluated audience reach (number of visit sessions, unique visitors, page views) and calculated top views by media type (animation, expert video, patient video, and slide show) and top retention videos from the modules. We also assessed the educational impact through learner feedback survey. RESULTS: The APP had 1,475,252 views (547,693 unique visitors, 63.1% in United States) during the study period. Most popular topic viewed among the animations was "Role and Anatomy of the Pancreas" (n = 361,116), and most common expert video viewed was "Chronic Pancreatitis: What Foods and Beverages Should I Avoid?" (n = 31,667). Participants who completed the online feedback survey reported knowledge gains and commitments to change. CONCLUSIONS: Pancreas education in visual formats of learning provided by APP demonstrated wide reach and has substantial potential to inform and impact behaviors of patients and caregivers. Continued efforts should be made to provide patient resources that address health literacy and patient education and respond to patient needs for better quality of life and improved health outcomes in pancreatic diseases. PMID- 30286014 TI - Pathophysiological Events Associated With Pancreatitis in Response to Tobacco: An In Vitro Comparative Study With Ethanol in Primary Acinar Cell Culture. AB - OBJECTIVES: The aim of this study was to comparatively analyze the effects of different concentrations of cigarette smoke condensate (CSC, a standardized tobacco extract) and ethanol on intracellular enzyme activation, cell necrosis, alteration of cytosolic calcium concentration ([Ca]c), and amylase secretion in pancreatic acinar cells. METHODS: The effects of CSC (1 MUg/mL to 0.4 mg/mL) and ethanol (10-100 mM) on intracellular enzyme activity, cell necrosis, and [Ca]c were measured by fluorescence assays in isolated pancreatic acinar cells. Amylase secretion was evaluated by spectrophotometry. Supramaximal concentrations of cholecystokinin (10-100 nM) were used as positive control. RESULTS: Neither CSC nor ethanol induced trypsin or elastase activation. Both CSC (0.1-0.4 mg/mL) and ethanol (10-75 mM) significantly increased [Ca]c. Amylase secretion was increased only in CSC-treated cells (0.3 and 0.4 mg/mL). After 60 minutes, CSC (0.3 and 0.4 mg/mL) significantly increased acinar cell necrosis at a similar percentage to that induced by cholecystokinin. Ethanol did not induce any significant cell necrosis. CONCLUSIONS: Cigarette smoke condensate induces acinar cell injury and increases [Ca]c and amylase secretion, independently of intracellular enzyme activation, suggesting that tobacco could induce several main early events of pancreatitis in pancreatic acinar cells. However, ethanol only induces increases [Ca]c, having no effect on cell injury, amylase secretion, or intracellular enzyme activation. PMID- 30286015 TI - Predictive Factors for Autoimmune Pancreatitis Relapse After 3 Years of Maintenance Therapy. AB - OBJECTIVES: Oral corticosteroid treatment is the standard therapy for autoimmune pancreatitis (AIP) and is highly effective. However, relapse may occur during maintenance therapy (MT). We aimed to clarify the predictive factors for relapse after 3 years of MT for use in deciding on the continuation of long-term MT. METHODS: Among 56 retrospectively recruited AIP patients who received corticosteroid remission induction therapy followed by MT for a minimum of 5 years, 38 subjects were enrolled after exclusion criteria and divided into the relapse group of patients who experienced relapse after 3 years of MT and the nonrelapse group of patients who did not. RESULTS: According to multivariate analysis, at least 4 other organ involvement numbers at diagnosis (hazard ratio, 5.82; 95% confidence interval, 1.203-28.192) and IgG of 1400 mg/dL or greater at 3 years of MT (hazard ratio, 4.41; 95% confidence interval, 1.096-17.790) were predictive factors for relapse after MT for 3 years, with patients exhibiting both predictive factors having a higher cumulative relapse rate than those with 1 or fewer predictive factor. CONCLUSIONS: We uncovered 2 predictive factors for AIP relapse after 3 years of MT. These findings will assist in deciding corticosteroid therapy regimens at 3 years of MT to minimize AIP relapse risk and adverse corticosteroid effects. PMID- 30286016 TI - Concordance of the Balthazar Grade and the Revised Atlanta Classification: Proposing a Modified Balthazar Grade to Predict the Severity of Acute Pancreatitis in Pediatric Population. AB - OBJECTIVES: The aim of this study was to compare the concordance of the Balthazar grade and the revised Atlanta classification and then establish a modified radiological scoring system that would predict 3 degrees of severity of acute pancreatitis (AP) based on the latest Atlanta classification. METHODS: A retrospective study enrolling pediatric inpatients with AP who had completed computed tomography was conducted between January 2006 and March 2018. The concordance of the 2 radiological scoring systems was assessed with kappa statistic. RESULTS: The Balthazar grade was unable to accurately predict the severity of AP compared with the revised Atlanta classification. However, a modified Balthazar grading system defining patents with Balthazar grades A to C as mild, grade D as moderately, and grade E as severe presented perfect agreement with the revised Atlanta classification across the enrolled population (kappa, 0.85; 95% confidence interval, 0.73-0.97). The concordance of the modified Balthazar score and the revised Atlanta classification remained a perfect degree of agreement across repeated tests in 90 random samples (kappa, 0.85; 95% confidence interval, 0.85-0.85). CONCLUSIONS: The modified Balthazar grade demonstrated perfect agreement with the latest Atlanta classification for AP severity scoring. As such, the modified Balthazar grade can be used to predict 3 degrees of severity of AP. PMID- 30286017 TI - More Than Just a Game: The Public Health Impact of Sport and Physical Activity for People With Disabilities (The 2017 DeLisa Lecture). AB - Although people with disabilities make up a large proportion of our global population and are known to be disproportionately impacted by sedentary lifestyles leading to chronic disease, programs promoting physical activity often fail to address their unique needs. Both environmental and attitudinal factors also act as barriers to full participation. In this context, increasing evidence shows the positive impact of physical activity and sport on outcomes related to physical health, mental health, community participation, and, in some cases, neurorecovery for people with disabilities. Thus, participation should be seen not only as a medical intervention, but also as a rights-based issue. We, as physiatrists, can be agents of change by promoting concepts of universal design and inclusion in physical activity and sport programs. PMID- 30286018 TI - Distinct patterns of fiber type adaptation in rat hindlimb muscles 4 weeks after hemorrhagic stroke. AB - OBJECTIVE: The aim of this study was to evaluate adaptations in soleus (SOL) and tibialis anterior (TA) muscles in a rat model 4 weeks after hemorrhagic stroke. DESIGN: Young adult Sprague-Dawley rats were randomly assigned to two groups: stroke (STR) and control (CTRL), with 8 SOL and 8 TA muscles per group. Hemorrhagic stroke was induced in the right caudoputamen of the STR rats. CTRL rats had no intervention. Neurologic status was evaluated in both groups pre stroke, and four weeks post-stroke. Muscles were harvested after post-stroke neurologic testing. Muscle fiber types and cross-sectional areas were determined in SOL and TA using immunohistochemical labeling for myosin heavy chain (MHC). RESULTS: No generalized fiber atrophy was found in any of the muscles. Fiber types shifted from faster to slower in the TA of the STR group, but no fiber type shifts occurred in the SOL muscles of STR animals. CONCLUSION: Since slower MHC fiber types are associated with weaker contractile force and slower contractile speed, this faster-to-slower fiber type shift in TA muscles may contribute to weaker and slower muscle contraction in this muscle after stroke. This finding may indicate potential therapeutic benefit from treatments known to influence fiber type plasticity.

PMID- 30286023 TI - Association Between Hospital and Surgeon Volume and Rectal Cancer Surgery Outcomes in Patients With Rectal Cancer Treated Since 2000: Systematic Literature Review and Meta-analysis. AB - BACKGROUND: Previous reviews and meta-analyses, which predominantly focused on patients treated before 2000, have reported conflicting evidence about the association between hospital/surgeon volume and rectal cancer outcomes. Given advances in rectal cancer resection, such as total mesorectal excision, it is essential to determine whether volume plays a role in rectal cancer outcomes among patients treated since 2000. OBJECTIVE: The purpose of this study was to determine whether there is an association between hospital/surgeon volume and rectal cancer surgery outcomes among patients treated since 2000. DATA SOURCES: We searched PubMed and EMBASE for articles published between January 2000 and December 29, 2017. STUDY SELECTION: Articles that analyzed the association between hospital/surgeon volume and rectal cancer outcomes were selected. INTERVENTION: Rectal cancer resection was the study intervention. MAIN OUTCOME MEASURES: The outcome measures of this study were surgical morbidity, postoperative mortality, surgical margin positivity, permanent colostomy rates, recurrence, and overall survival. RESULTS: Although 2845 articles were retrieved and assessed by the search strategy, 21 met the inclusion and exclusion criteria. There was a significant protective association between higher hospital volume and surgical morbidity (OR = 0.80 (95% CI, 0.70-0.93); I = 35%), permanent colostomy (OR = 0.51 (95% CI, 0.29-0.92); I = 34%), and postoperative mortality (OR = 0.62 (95% CI, 0.43-0.88); I = 34%), and overall survival (OR = 0.99 (95% CI, 0.98 1.00); I = 3%). Stratified analysis showed that the magnitude of association between hospital volume and rectal cancer surgery outcomes was stronger in the United States compared with other countries. Surgeon volume was not significantly associated with overall survival. The articles included in this analysis were high quality according to the Newcastle-Ottawa scale. Funnel plots suggested that the potential for publication bias was low. LIMITATIONS: Some articles included rectosigmoid cancers. CONCLUSIONS: Among patients diagnosed since 2000, higher hospital volume has had a significant protective effect on rectal cancer surgery outcomes.

AB - INTRODUCTION: Ultrasound-guided central venous catheter insertion (UGCVC) is a commonly performed procedure taught through simulation. The aims of the study were to examine the utilization of an animal model and compare it with two currently used Blue Phantom central line models to determine whether an animal model provides good or better simulated conditions for the performance of UGCVC insertion. METHODS: Using a randomized cross-over study, 46 advanced practice nursing students were assessed using a task-specific performance tool in their performance of UGCVC insertion on both the animal model and the Blue Phantom models. The number of insertion attempts and time to performance was recorded. A preprocedure survey was used to ascertain their presimulation workshop experience, followed by a postprocedure survey. A cost comparison was completed as a secondary outcome. RESULTS: A comparison was conducted on the performance scores and the postsurvey results between the animal model and the Blue Phantom models. The number of venous access attempts was not significantly different when comparing the three models. A cost comparison showed the total cost of each animal model was US $15.66 as compared with the approximate cost for the Blue Phantom IJ model of US $1500.00 and the Gen I model of US $2700.00. CONCLUSIONS: Current Blue Phantom models lack the ability to fully perform all the necessary steps critical to the performance of UGCVC insertion. At a total cost of US $15.66 per model, this study showed that training with an alternative economical model was comparable with more expensive mannequin simulators. The results of this study may serve to guide clinicians and educators who are seeking alternative simulation models to provide skill acquisition.

PMID- 30286031 TI - Angiopoietin Level Trajectories in Toddlers with Severe Sepsis and Septic Shock and Their Effect on Capillary Endothelium. AB - OBJECTIVE: Angiopoietins are postulated diagnostic biomarkers in children and adults with severe sepsis and septic shock. The diagnostic value of angiopoietins in children less than 5 years old has not been established, nor has their effect on permeability in the capillary microvasculature. We aim to determine if levels of angiopoietin-1 or -2 (angpt-1, -2) are diagnostic for severe sepsis/shock in young children and whether they affect the permeability of cultured human dermal microvascular endothelial cells (HDMEC). DESIGN: Prospective observational study of children< 5 years old. Patients were classified as non-systemic inflammatory response syndrome (SIRS), SIRS/sepsis and severe sepsis/septic shock. SETTING: Tertiary care pediatric hospitals. PATIENTS: Critically ill children. INTERVENTIONS: None MEASUREMENTS:: Plasma angpt-1 and -2 levels were measured with ELISA. Expression of angpt-2 in endothelial cells was assessed with quantitative polymerase chain reaction. Permeability changes in cultured HDMECs were assessed with trans-endothelial electrical resistance (TEER) measurements. RESULTS: Angpt-1 levels were significantly higher in younger children compared to levels found in previous study of older children across disease severity (all p < 0.001). Angpt-2 was significantly higher in this cohort with severe sepsis/septic shock compared to children without SIRS and SIRS/sepsis (all p < 0.003). Angpt 2/1 ratio was also elevated in children with severe sepsis/septic shock but an order of magnitude less than older children (p < 0.02, p = 0.002). Angpt-1 and -2 did not affect basal HDMEC permeability or modulate leak in isolation or in the presence of tumor necrosis factor (TNF). CONCLUSIONS: Angpt-2 levels and the angpt-2/1 ratio are appropriate diagnostic biomarkers of severe sepsis/septic shock in children less than 5 years old. Neither angpt-1 nor -2 affects basal HDMEC permeability alone or modulates TNF induced capillary leak. PMID- 30286033 TI - Enhancing Autophagy Protects Against Sepsis-Induced Neuromuscular Dysfunction Associated with Qualitative Changes to Acetylcholine Receptors. AB - Sepsis-induced myopathy is a heavy burden for patients during respiratory failure as well as after discharge, which could be characterized with qualitative changes to nAChR in a rat model of sepsis, regulated by NRG-1. Autophagy is an innate immune defense mechanism against microbial challenges. We found neuromuscular dysfunction in anterior tibial muscle of male Sprague-Dawley rats 24 h after cecal ligation and puncture (CLP). CLP resulted in increased systemic and local inflammation in anterior tibial muscle tissue. The start-up phase of autophagy, as measured by LC3II, was activated immediately after CLP and continued until 24 h; the degradation phase was suppressed until 24 h, after a brief increase at 4 h (revealed by p62). NRG-1 first increased, and then decreased to a level lower than that in the sham group. Meanwhile, expression of gamma- and alpha7- acetylcholine receptors was detected at 8 and 16 h after CLP; levels increased continuously until 24 h. Subsequently, we investigated the significance of autophagy in CLP-induced neuromuscular dysfunction by treatment with rapamycin or 3-methyladenine, which were classical pharmaceuticals for enhancing or suppressing autophagy. Rapamycin activated autophagy, limited the CLP-induced systemic pro-inflammatory response and blood bacterial load without affecting local inflammatory response, upregulated NRG-1, downregulated gamma- and alpha7 acetylcholine receptors, and improved 7-day neuromuscular function and survival rate. In contrast, 3-methyladenine enhanced local inflammatory response, suppressed autophagy, worsened 7-day neuromuscular function. We conclude that impaired autophagy may contribute to sepsis-induced neuromuscular dysfunction in young male rats. Enhancing autophagy with rapamycin alleviated qualitative changes to acetylcholine receptors without triggering local anti-inflammatory response and improved anterior tibial muscle function in septic early phase (24 h) as well as in septic chronic phase (7d). Enhancing autophagy soon after sepsis is a potential strategy for treatment of sepsis-induced myopathy. PMID- 30286034 TI - The Role of Mitochondrial DNA in The Development of Ischemia Reperfusion Injury. AB - Ischemia/reperfusion (I/R) injury is a common occurrence resulting from acute mesenteric ischemia, traumatic or septic shock, burns, and surgical procedures that can lead to multiple organ failure and high mortality in critically ill patients. Mitochondria are often considered as the cellular power factory via their capacity for ATP generation. Recently, mitochondria have been further identified as vital regulators of cell death, inflammation, and oxidative stress, all of which can aggravate I/R injury. Studies have indicated that mitochondrial DNA (mtDNA) damage leads to mitochondrial dysfunction and aggravates I/R injury. mtDNA is emerging as an agonist of the innate immune system that influences inflammatory pathology during I/R injury. In addition, when mtDNA is released into the cytoplasm, extracellular milieu or circulation, it can activate multiple pattern-recognition receptors to trigger type I interferon and pro-inflammatory responses. Here, we review the emerging role of mtDNA in I/R injury to highlight novel mechanistic insights and discuss the pathophysiological relevance of mitochondrial biology. PMID- 30286032 TI - Lactate is a Prognostic Factor in Patients Admitted with Suspected ST-Elevation Myocardial Infarction. AB - AIMS: The diagnosis of cardiogenic shock depends on clinical signs of poor perfusion and low blood pressure. Lactate concentration will increase with poor tissue perfusion, and it has prognostic value in cardiogenic shock patients. We sought to assess the prognostic value of lactate concentration in subjects admitted with suspected ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS: In 2094 (93%) out of 2247 consecutive suspected STEMI-subjects, lactate concentration was measured on admission. The prognostic value of lactate concentration on 30-day mortality was assessed in addition to clinical signs of peripheral hypoperfusion, systolic blood pressure (sBP), and left ventricular ejection fraction (LVEF) in multivariable models.Lactate concentration added prognostic information beyond signs of peripheral hypoperfusion, sBP and LVEF, and was independently associated with 30-day mortality (Hazard ratio (95% confidence interval) 1.11 (1.07 - 1.14), p < 0.0001). Lactate also provided predictive information on 30-day mortality to the combination of signs of peripheral hypoperfusion, sBP, and LVEF (area under the receiver-operating characteristics curve = 0.88 vs. 0.83, p < 0.0001). CONCLUSIONS: In conclusion, admission lactate concentration in suspected STEMI-subjects contains prognostic information on 30-day mortality when added to variables used in cardiogenic shock definition. We recommend lactate measurement in STEMI-subjects, especially when signs of compromised hemodynamics are present. PMID- 30286035 TI - Circulating Monocyte Counts and its Impact on Outcomes in Patients with Severe Sepsis Including Septic Shock. AB - This study was performed to evaluate the association of monocyte counts with mortality, the rate of bacteremia and organ dysfunction and to evaluate whether the change in monocyte counts from the premorbid state to sepsis would differ between survivors and non-survivors in patients with severe sepsis including septic shock. A retrospective analysis of patients with severe sepsis including septic shock was performed. Monocyte counts were categorized into < 250, 250 - 500, 500 - 750 and >= 750 cells/MUL; in addition, 28-day mortality, the rate of bacteremia and organ dysfunction were compared between the groups. Multivariate logistic regression analyses were performed to evaluate the independent association of initial blood cell counts with 28-day mortality. Subgroup analyses of patients who had premorbid data of blood cell counts were performed to evaluate the difference in the change in monocyte counts between survivors and non-survivors. During the study period, 2012 patients were included. Neutrophil and monocyte counts were significantly different between survivors and non survivors. However, only monocyte counts were independently associated with mortality in the multivariate logistic regression analyses. Patients with initial monocyte counts < 250 cells/MUL showed the highest mortality, rate of bacteremia and organ dysfunction. In patients who had premorbid blood cell counts, the monocyte counts increased in survivors but decreased in non-survivors from the premorbid to sepsis. In conclusion, monocyte counts were associated with mortality, the rate of bacteremia and organ dysfunction in patients with sepsis, possibly due to the relative lack of monocytopoiesis related with septic insults in non-survivors. PMID- 30286036 TI - Endoplasmic Reticulum Stress-Induced NLRP1 Inflammasome Activation Contributes to Myocardial Ischemia/Reperfusion Injury. AB - Studies have shown that Nod-like receptor protein (NLRP) 3 inflammasome activation contributes to myocardial ischemia/reperfusion (I/R) injury. However, the role and mechanism of NLRP1 inflammasome in myocardial I/R injury remains unknown. Endoplasmic reticulum (ER) stress is involved in the development of myocardial I/R injury. The relationship between ER stress and NLRP1 inflammasome in myocardial I/R injury needs further study. NLRP1 inflammasome activation and ER stress were investigated in hypoxia/reoxygenation (H/R)-treated primary mouse cardiomyocytes and left anterior descending coronary artery ligation and reperfusion mouse models. Downregulation of NLRP1 expression with NLRP1 siRNA was used to evaluate the role of NLRP1 inflammasome in H/R-stimulated cardiomyocyte injury. 4-phenylbutyric acid (4-PBA), an ER stress inhibitor, was used to pretreat cardiomyocytes before H/R treatment, the cardiomyocyte injury and NLRP1 inflammasome activation were determined. Also, NF-kappaB signaling activity was measured. Additionally, PDTC, an NF-kappaB inhibitor, was used to treat cardiomyocytes before H/R stimulation and NLRP1 inflammasome activation was examined. We found the levels of ER stress markers GRP78, p-PERK, p-eIF2alpha and CHOP as well as NLRP1 inflammasome activation were significantly elevated both in vivo and in vitro. NLRP1 siRNA notably increased cell viability inhibited by H/R, suppressed H/R-induced cell apoptosis, LDH release and creatine kinase activity. 4-PBA reduced H/R-stimulated cardiomyocyte injury via NLRP1 inflammasome inactivation, and it also suppressed NF-kappaB signaling activity. NLRP1 inflammasome activation induced by H/R was also suppressed by PDTC. In conclusion, NLRP1 inflammasome activation promotes myocardial I/R injury. ER stress can activate NLRP1 inflammasome via activating the NF-kappaB signaling pathway. PMID- 30286038 TI - Recent progress in understanding immune activation in the pathogenesis in HIV tuberculosis co-infection. AB - PURPOSE OF REVIEW: Tuberculosis is the leading infectious cause of death worldwide, and HIV-1 the best recognized risk factor for active TB. This review focuses on immune complex formation; the interplay of type I and II interferon signaling; and T-cell activation in HIV-TB pathogenesis. RECENT FINDINGS: Circulating immune complexes and complement, and Fcgamma signaling in whole blood act as early markers of TB disease in HIV-1-infected persons. HIV-1 is associated with a type I interferon response in whole blood, reducing the specificity of TB biomarkers dependent on type I and II interferon genes. Type I and type II interferons are implicated in both protection and TB disease, a protective outcome may depend on modulating these pathways. Whilst M. tuberculosis-specific CD4 T cells are preferentially depleted during HIV-1 infection, activation markers on M. tuberculosis-specific CD4 T cells, in particular HLA-DR, reflect immune activation and have promise as biomarkers of M. tuberculosis disease activity in individuals with HIV-1. SUMMARY: TB pathogenesis in HIV-1 involves a complex interaction of underlying activation of both the innate and adaptive immune systems. Further research is required to understand whether biomarkers of activation could be used to predict or quantify TB disease in the context of HIV 1 infection. PMID- 30286039 TI - Treatment of drug-resistant tuberculosis among people living with HIV. AB - PURPOSE OF REVIEW: This review aims to describe the key principles in treatment of drug-resistant tuberculosis (TB) in people living with HIV, including early access to timely diagnostics, linkage into care, TB treatment strategies including the use of new and repurposed drugs, co-management of HIV disease, and treatment complications and programmatic support to optimize treatment outcomes. These are necessary strategies to decrease the likelihood of poor treatment outcomes including lower treatment completion rates and higher mortality. RECENT FINDINGS: Diagnosis of drug-resistant TB is the gateway into care; yet understanding the utility and the limitations of genotypic methods in this population is necessary. The principles of TB treatment in HIV-infected individuals are similar to those without HIV co-infection, with few exceptions. However, adverse effects with potential significant morbidity may emerge during treatment, and timely antiretroviral therapy is essential to improve mortality in this patient population. Emerging data on the use of new and repurposed drugs and short course multidrug-resistant TB regimens and adherence strategies benefiting this population are reviewed. SUMMARY: The clinical complexity of co-managing drug-resistant TB and HIV, and the higher rate of poor treatment outcomes in this population demand careful clinical management strategies, and multidisciplinary and comprehensive programmatic interventions to optimize treatment success in this vulnerable group. PMID- 30286040 TI - HIV-associated pediatric tuberculosis: prevention, diagnosis and treatment. AB - PURPOSE OF REVIEW: The detrimental synergy of colliding HIV and tuberculosis (TB) epidemics is most devastating among children and adolescents living with HIV (CALWH) who shoulder a disproportionate burden of all child TB mortality. RECENT FINDINGS: CALWH benefit less from Bacille-Calmette Guerin vaccination than HIV uninfected children and are not receiving TB preventive therapy despite global recommendations. Further, the predictive utility of most diagnostic tools is reduced in CALWH. Finally, antiretroviral and anti-TB drug interactions continue to complicate cotreatment for children. Despite these challenges, recent data fuel a new awareness of TB as a hidden cause of child mortality and a renewed commitment to TB prevention. New diagnostic approaches using existing tools with novel specimens, such as stool, may improve the diagnosis of TB in CALWH. Further, pharmacokinetic studies and the development of new drug formulations promise better treatment options for CALWH in the near future. SUMMARY: With the awareness that TB is the leading cause of mortality among CALWH, comes a responsibility to accelerate research to prevent, diagnose and treat TB in this vulnerable population. In the present, we must adopt evidence-based preventive and treatment strategies to enhance outcomes of CALWH and combating TB. PMID- 30286041 TI - Preventive therapy for HIV-associated tuberculosis. AB - PURPOSE OF REVIEW: Tuberculosis (TB) remains the leading cause of death in people living with HIV (PLHIV) despite the achievements in antiretroviral therapy coverage. TB preventive therapy (TPT) has proved efficacy but has been neglected and poorly implemented. We reviewed recent publications and guidelines about TPT in PLHIV. RECENT FINDINGS: High-quality studies showed that TPT has a durable effect, over 5 years, preventing TB and all-cause mortality. There is new evidence showing the noninferiority of shorter, rifamycin-based regimens of TPT increasing the options for treatment. Recent studies describing robust implementation in different settings showed promising results for feasibility, tolerance, retention, and cost-effectiveness. New WHO recommendations, unifying previous versions, have been released to guide countries implementation. SUMMARY: New evidence support the scale up of TPT for PLHIV globally, further studies are needed to bring more evidence for specific populations, like pregnant women and for drug-drug interactions with antiretroviral agents. PMID- 30286042 TI - Identifying priorities for HIV-associated tuberculosis research through the WHO guidelines process. AB - PURPOSE OF REVIEW: Guidelines developed by the WHO aim to provide recommendations to support best practice in health delivery, with a focus on low-income and middle-income countries. As part of the guideline development process, critical knowledge gaps are identified and one of the core functions of WHO guidelines is to set forth priorities for future research. A review of research priorities identified through the WHO guideline development has recently been promoted as one approach to building an overarching priority research agenda in a given area. This paper outlines priorities for HIV-associated TB research identified in WHO HIV and TB guidelines published since 2015. RECENT FINDINGS: Nine guidelines were reviewed and 29 priority research questions were identified. Research priorities were identified for prevention of HIV-associated TB (11 questions), screening of latent and active TB in people living with HIV (six questions), treatment of drug sensitive (four questions), and drug-resistant (two questions) TB, and treatment of HIV in people coinfected with TB (three questions). SUMMARY: Multiple approaches to defining priority research questions for health research exist. Research priorities that arise from the WHO guideline development process are limited to those areas for which guidelines are developed. One strength of this approach is that it takes as a starting point a desire to make actionable recommendations for policy makers. WHO is working to further refine the formulation of research questions within the guideline development process.

AB - The presence of online learning resources has grown tremendously in recent years. They provide powerful and yet easily accessible means of learning and sharing knowledge. Online learning resources now encompass all aspects of medicine, and microsurgery is no exception. International Microsurgery Club (IMC) is a closed, invitation-only group based on the Facebook social media platform. It was initiated on May 6, 2016, with primary objectives of providing a convenient forum for discussing challenging cases, sharing valuable resources, and providing opportunities for research collaboration. The membership of IMC has grown over 8700 at two year of existence, and continues to expand. IMC has become one of the largest online platforms for global microsurgeons. Here, we share our experience on how to establish a successful online platform for medical education. PMID- 30286044 TI - Minimal pain with Prepectoral implant based breast reconstruction. PMID- 30286045 TI - Does reconstruction preserving the first or first two rays benefit over full transmetatarsal amputation in diabetic foot? AB - BACKGROUND: The benefits of total transmetatarsal amputation (TMA) over higher level amputation are well known. However, there are no studies evaluating the effects of first or the first two ray sparing transmetatarsal amputation with flap coverage. We evaluated this approach in regards to functional outcome and to identify long-term complications. MATERIAL AND METHOD: Retrospective data of 59 patients were evaluated according to their surgical method. Complete TMA with free flap reconstruction was designated as group TMA with 27 patients and first or first two rays preserving TMA with free flap reconstruction was designated as group Ray with 32 patients. Demographics, flap outcomes, additional procedures after initial healing and functional outcomes were measured and evaluated. RESULTS: There was no statistical significant difference in demographic distribution and flap outcomes in either group except poor blood sugar control in group Ray. Additional procedures after initial healing showed no statistical difference but the tendency of minor procedures was higher in group Ray. The maximum achieved ambulatory function was significantly better in group Ray with an ambulatory function score of 4.4 over 3.7 in group TMA (p= 0.012). CONCLUSION: The preservation of the first or first two rays with free flap reconstruction may functionally benefit the patients despite the higher tendency of minor procedures after initial healing. Furthermore, the progressive deformity of the preserved first and second toes will inevitably occur requiring patients to undergo further surgery. Further studies are warranted to evaluate this approach. PMID- 30286046 TI - Current Use of Biological Scaffolds in Plastic Surgery. AB - Properly designed biodegradable scaffolds facilitate repair or regeneration of stromal tissues. Over the last 50 years, a variety of synthetic, semi-synthetic and decellularized scaffolds have been developed that provide surgeons with tools to reconstruct a wide array of structural defects.We reviewed the literature of biological degradable scaffolds in current clinical use in the US and highlight their design principles as well as products in common use.Host tissues populate scaffolds with inflammatory cells, fibroblasts, blood vessels, nerves and lymphatics. Cells lay down extracellular matrix macromolecules while enzymes degrade the scaffold. Over time the scaffold can be totally replaced by host tissues.The greatest use of scaffolds in plastic surgery is in skin replacement, breast reconstruction, abdominal wall reconstruction and peripheral nerve repair. Other areas of importance are cartilage and bone replacement as well as support for lining replacements such bowel, bladder, mucosa and dura. The wide range of research being done in this field is likely to provide surgeons with more choices and improved materials to repair and regenerate stromal structures. PMID- 30286047 TI - Assessing Quality of Life and Patient-Reported Satisfaction with Masculinizing Top Surgery: A Mixed-Methods Descriptive Survey Study. AB - BACKGROUND: Masculinizing top surgery (bilateral mastectomy with chest wall reconstruction) is an important gender-affirming procedure sought by many transmasculine and non-binary individuals. Current literature is primarily focused on details of surgical technique and complication rates, with limited data available on how top surgery affects subjective quality of life measures. METHODS: An anonymous online survey was distributed to 81 of the senior author's former top surgery patients. Survey response rate was 72% (58 respondents). Responses were analyzed to investigate quality of life, sexual confidence, mental health, satisfaction with top surgery, and patient attitudes toward top surgery's role in gender affirmation. RESULTS: Following top surgery, measures of quality of life and sexual confidence significantly improved (P < .001). Additionally, 86% reported improvement in gender dysphoria-related mental health conditions. All but 1 respondent reported that top surgery had an overall positive impact on their life. CONCLUSIONS: Top surgery had major positive effects on all mental health and quality of life metrics. Our findings contribute to a much-needed body of evidence that top surgery markedly improves the daily lives and functioning of transgender and non-binary individuals who choose to undergo it. PMID- 30286048 TI - Reporting Adverse Events in Plastic Surgery: A Systematic Review of Randomized Controlled Trials. AB - BACKGROUND: Accurate knowledge of adverse events is critical for evaluation of the safety and efficacy of interventions. Historically, adverse events in surgical trials have been poorly reported. The objective of this study was to systematically evaluate the reporting of adverse events in randomized controlled trials (RCTs) in the plastic surgery literature. METHODS: Two independent reviewers conducted a systematic search using MEDLINE, EMBASE, and SCOPUS of the top seven plastic surgery journals with the highest impact factors. RCTs describing a potentially invasive treatment, published between January 2012 and December 2016, were included. RESULTS: One hundred and forty-five RCTs involving 10,266 patients were included, of which 30% were registered. Anticipated adverse events were clearly defined in 15% of trials, and in 70% it was not clear who would be documenting adverse events. Furthermore, 72% of RCTs reported the occurrence of adverse events, of which 61% failed to report events occurring in the intra-interventional period. Of the trials not documenting any adverse event, two-thirds included a statement declaring that no adverse events had occurred. Binary logistic regression revealed that funded RCTs were 4.04 times more likely to report adverse events compared to non-funded RCTs (95% CI 1.41-10.83, p=0.009). CONCLUSIONS: Our findings suggest the need for reporting standards for adverse events in the plastic surgery literature, as such reporting remains heterogeneous and is lacking rigor. Improved quality and transparency is needed to strengthen evidenced-based practice and permit a balanced intervention assessment. This study provides a set of recommendations aimed at improving adverse event reporting. PMID- 30286049 TI - Sensory Modulation: An Important Piece of the Disability Puzzle for Adolescents with Persistent Pain. AB - OBJECTIVES: Sensory modulation patterns contribute to altered pain perception and disengagement in activities; atypical sensory modulation patterns have been associated with higher pain sensitivity, catastrophizing, and reduced function. Objectives of this study were to ascertain whether: adolescents with persistent pain had atypical sensory modulation patterns, atypical sensory modulation was associated with reduced functioning and higher pain, and pain catastrophizing mediated the relationship between sensory modulation and functional disability. METHODS: Adolescents (N=70, Females=63, Males=7) attending tertiary level interdisciplinary team assessment for persistent pain completed sensory modulation (Adolescent/Adult Sensory Profile), pain catastrophizing (Bath Adolescent Pain Questionnaire), pain intensity, functional disability (Functional Disability Index), and quality of life (Pediatric Quality of Life (QOL) Scales) questionnaires. RESULTS: Adolescents with persistent pain had atypical patterns of sensory modulation compared to normative data. Sensory modulation patterns were not associated with pain intensity; however, higher sensitivity was associated with greater disability (r=0.36, P<0.01), and lower registration of sensation was associated with poorer emotional (r=0.31, P<0.01), social (r=0.35, P<0.01), and school-related (r=0.49, P<0.001) QOL. Sensory modulation, pain intensity, and catastrophizing contributed independently to disability; catastrophizing mediated sensory sensitivity and both functional disability and emotional QOL. DISCUSSION: This study is the first to demonstrate that atypical sensory modulation patterns are associated with poorer function for adolescents with persistent pain, suggesting that individualized sensory-informed interventions can potentially facilitate participation in daily activities and improve QOL.

PMID- 30286052 TI - Outbreak of Salmonella Chailey Infections Linked To Precut Coconut Pieces - United States and Canada, 2017. AB - Foodborne salmonellosis causes an estimated 1 million illnesses and 400 deaths annually in the United States (1). In recent years, salmonellosis outbreaks have been caused by foods not typically associated with Salmonella. On May 2, 2017, PulseNet, CDC's national molecular subtyping network for foodborne disease surveillance, identified a cluster of 14 Salmonella Chailey isolates with a rare pulsed-field gel electrophoresis (PFGE) pattern. On May 29, Canadian health officials informed CDC that they were also investigating a cluster of five Salmonella Chailey infections in British Columbia with the same PFGE pattern. Nineteen cases were identified and investigated by CDC, U.S. state health departments, the Public Health Agency of Canada, and the British Columbia Centre for Disease Control. Isolates from all cases were highly related by whole genome sequencing (WGS). Illness onset dates ranged from March 10 to May 7, 2017. Initial interviews revealed that infected persons consumed various fresh foods and shopped at grocery chain A; focused questionnaires identified precut coconut pieces from grocery chain A as a common vehicle. The Canadian Food Inspection Agency (CFIA) and the U.S. Food and Drug Administration (FDA) conducted a traceback investigation that implicated a single lot of frozen, precut coconut as the outbreak source. Grocery chain A voluntarily removed precut coconut pieces from their stores. This action likely limited the size and scope of this outbreak. PMID- 30286050 TI - Rs4938723 Polymorphism Is Associated with Susceptibility to Hepatocellular Carcinoma Risk and Is a Protective Factor in Leukemia, Colorectal, and Esophageal Cancer. AB - BACKGROUND Growing evidence indicates that a non-coding RNA named miR-34b/c plays crucial roles in carcinogenesis, and its common polymorphism, pri-miR-34b/c rs4938723, also participates in this process and is associated with cancer susceptibility. However, this association was previously undefined and ambiguous. Therefore, we carried out an updated analysis to evaluate this relationship between rs4938723 polymorphism and cancer susceptibility. MATERIAL AND METHODS PubMed, EMbase, Web of Science and Chinese language (WanFang, CNKI and VIP) databases were searched for relevant studies until Sep 10, 2018. Odds ratios and 95% confidence interval were applied to assess this relationship. RESULTS Thirty case-control studies were retrieved. No positive association was found in either the overall study population or in the subgroups, based on ethnicity, source of group, sex, smoking, and drinking status. The main results were observed in the stratified analysis subgroups in cancer type subgroup: rs4938723 polymorphism may be a protective factor in leukemia, colorectal cancer, and esophageal cancer; however, C-allele was a risk factor in carriers for hepatocellular carcinoma. Last but not the least, poor positive results were discovered in the age subgroup. CONCLUSIONS Current meta-analysis suggested that rs4938723 polymorphism was potentially associated with hepatocellular carcinoma risk, but this polymorphism had a decreased association for susceptibility to esophageal cancer, leukemia, and colorectal cancer. Furthermore, studies with larger sample sizes and including gene-gene or gene-environment interactions should be carried out to elucidate the role of rs4938723 polymorphism in cancer risk.

PMID- 30286053 TI - Symptoms of Anxiety and Depression Among Adults with Arthritis - United States, 2015-2017. AB - An estimated 54.4 million (22.7%) U.S. adults have doctor-diagnosed arthritis (1). A report in 2012 found that, among adults aged >=45 years with arthritis, approximately one third reported having anxiety or depression, with anxiety more common than depression (2). Studies examining mental health conditions in adults with arthritis have focused largely on depression, arthritis subtypes, and middle aged and older adults, or have not been nationally representative (3). To address these knowledge gaps, CDC analyzed 2015-2017 National Health Interview Survey (NHIS) data* to estimate the national prevalence of clinically relevant symptoms of anxiety and depression among adults aged >=18 years with arthritis. Among adults with arthritis, age-standardized prevalences of symptoms of anxiety and depression were 22.5% and 12.1%, respectively, compared with 10.7% and 4.7% among adults without arthritis. Successful treatment approaches to address anxiety and depression among adults with arthritis are multifaceted and include screenings, referrals to mental health professionals, and evidence-based strategies such as regular physical activity and participation in self-management education to improve mental health.

AB - Congenital syphilis occurs when syphilis is transmitted from a pregnant woman to her fetus; congenital syphilis can be prevented through screening and treatment during pregnancy. Transmission to the fetus can occur at any stage of maternal infection, but is more likely during primary and secondary syphilis, with rates of transmission up to 100% at these stages (1). Untreated syphilis during pregnancy can cause spontaneous abortion, stillbirth, and early infant death. During 2013-2017, national rates of congenital syphilis increased from 9.2 to 23.3 cases per 100,000 live births (2), coinciding with increasing rates of primary and secondary syphilis among women of reproductive age (3). In New York City (NYC), cases of primary and secondary syphilis among women aged 15-44 years increased 147% during 2015-2016. To evaluate measures to prevent congenital syphilis, the NYC Department of Health and Mental Hygiene (DOHMH) reviewed data for congenital syphilis cases reported during 2010-2016 and identified patient-, provider-, and systems-level factors that contributed to these cases. During this period, 578 syphilis cases among pregnant women aged 15-44 years were reported to DOHMH; a congenital syphilis case was averted or otherwise failed to occur in 510 (88.2%) of these pregnancies, and in 68, a case of congenital syphilis occurred (eight cases per 100,000 live births).* Among the 68 pregnant women associated with these congenital syphilis cases, 21 (30.9%) did not receive timely (>=45 days before delivery) prenatal care. Among the 47 pregnant women who did access timely prenatal care, four (8.5%) did not receive an initial syphilis test until <45 days before delivery, and 22 (46.8%) acquired syphilis after an initial nonreactive syphilis test. These findings support recommendations that health care providers screen all pregnant women for syphilis at the first prenatal care visit and then rescreen women at risk in the early third trimester.

PMID- 30286058 TI - Rates of Carpal Tunnel Syndrome in a State Workers' Compensation Information System, by Industry and Occupation - California, 2007-2014. AB - Carpal tunnel syndrome (CTS) occurs when the median nerve becomes compressed as it passes through the wrist within the carpal tunnel, resulting in pain, tingling, weakness, or numbness in the hand or the wrist. Occupational risk factors for CTS include engaging in work activities that require forceful, repetitive tasks, prolonged use of the hands or wrists in an awkward posture, or vibration (1). To assess trends and identify high-risk industries and occupations for CTS, the California Department of Public Health (CDPH) analyzed California workers' compensation claims for CTS by industry (2007-2014) and occupation (2014) and calculated rates per full-time equivalent (FTE) worker. During 2007 2014, a total of 139,336 CTS cases were reported (incidence = 6.3 cases per 10,000 FTE) in California workers; the rate among women (8.2) was 3.3 times higher than that among men (2.5). Industries with the highest rates of CTS were textile, fabric finishing, and coating mills (44.9), apparel accessories and other apparel manufacturing (43.1), and animal slaughtering and processing (39.8). Industries with high rates of CTS should consider implementing intervention measures, including ergonomic evaluations and development of tools and instruments that require less repetition and force and that correct awkward postures. PMID- 30286060 TI - Use of tranexamic acid in trauma patients requiring massive transfusion protocol activation: an audit in a major trauma centre in New Zealand. AB - AIM: To investigate prescribing behaviours around tranexamic acid (TXA) use in the early management of severe trauma, and compare against standards considered to be best practice internationally, as established by the current body of research. METHODS: We undertook a retrospective analysis of all trauma patients requiring massive transfusion protocol (MTP) activation across a 20-month period. A combination of physical and electronic inpatient records and ambulance documentation were reviewed to determine dose and timing of TXA administration. RESULTS: During the period studied, 27 adult trauma patients who required activation of the MTP were identified. Of the patients where TXA was indicated, 76.2% received at least an initial dose of TXA, with 19.0% receiving both doses. 21.1% of patients who received TXA were administered an initial dose within one hour of injury, 52.6% between one and three hours, 26.3% outside three hours. CONCLUSIONS: TXA was found to be under-utilised and significant departures from best practice were found, likely due to persisting uncertainty and unfamiliarity. In particular, delayed administration beyond the three-hour therapeutic window occurred in a quarter of patients, increasing the risk of mortality secondary to haemorrhage. This pattern of use may apply to the wider population of trauma patients in this centre, and requires remedy and reassessment.

METHOD: Data was sourced from the Midland Trauma System Registry. Patients admitted to Midland hospitals from 2012 to 2015 were evaluated. Data included patient demography, location, mechanism, and time of the injury, type of animals involved, injuries sustained, interventions, outcomes and hospital costs. The final sample included 168 injury events. RESULTS: 75.6% were due to interactions with cattle. The remainder were from sheep, pigs and deer. Most of the injuries were either 'hit', 'crush' or 'kick' injuries. Moving and loading stock resulted in 38% of the injuries, and 29% occurred near fences, gates or poles. Cattle-related injuries peaked during September and October. Sheep-related injuries peaked in December. These months correspond to calving season in cows and shearing season in sheep. Injury peaks were observed in the 20 29 and 50-59 age groups. CONCLUSION: This study has identified high-risk animals, activities, age intervals and times during which large livestock-related injuries may occur, and revealed the significant impact on hospitals and communities that these injuries result in. PMID- 30286062 TI - Audit of ethnicity data in the Waikato Hospital Patient Management System and Trauma Registry: pilot of the Hospital Ethnicity Data Audit Toolkit. AB - BACKGROUND: Maori are disproportionately impacted by injury in New Zealand, therefore reliable ethnicity data are essential for measuring and addressing inequities in trauma incidence, care and outcomes. AIM: To audit the quality of ethnicity data captured by the Waikato Hospital Trauma Registry and Waikato Hospital patient management system against self-identified ethnicity. METHOD: Self-identified ethnicity using the New Zealand Census ethnicity question was gathered from 100 consecutive trauma patients and compared with ethnicity recorded in their Trauma Registry record and in the hospital's patient management database. RESULTS: Twenty-nine (29%) participants self-identified as Maori, of whom six were classified as New Zealand European (NZE) only in the Trauma Registry and five as NZE on the hospital patient management database. Over half of Maori (n=18/29) reported more than one ethnicity compared with 4% (n=3/71) of non-Maori. Self-identified ethnicity matched Trauma Registry ethnicity for one quarter (n=7/29) of Maori versus 9% of non-Maori. CONCLUSIONS: The degree of misclassification of Maori ethnicity data among patients in the Waikato Trauma Registry and the Waikato Hospital patient management system highlights a need for improvements to how ethnicity data is captured within these databases and potentially many other similar entities collecting ethnicity data in New Zealand. The release of revised standardised protocols for the collection of ethnicity data is timely given the recent establishment of a national trauma registry. Without quality data, the opportunity to investigate and address ethnic inequities in trauma incidence and management is greatly compromised. PMID- 30286063 TI - New Zealanders' experiences and pathways to a diagnosis of bowel cancer: a cross sectional descriptive study of a younger cohort. AB - AIMS: To understand colorectal cancer (CRC) symptoms experienced by Aotearoa/New Zealand patients and to describe patient-experienced pathways and factors which may be associated with delayed diagnosis. METHODS: Ninety-eight patients diagnosed with CRC, recruited via a national charity, completed a questionnaire. Questions included demographics, symptoms, help-seeking and diagnostic pathways followed. RESULTS: Of 98 participants, 72 (73%) were aged under 60 years; most were symptomatic (n=93, 95%) and first discussed symptoms with someone who was not a healthcare professional (HCP) (n=71, 79%). The first HCP approached was usually a general practitioner (n=81, 83%). Symptom-to-diagnosis interval (SDI) was often six months or more (n=52, 56%) among our younger cohort. Delay was more likely if patients were younger (P=0.05), without a tertiary qualification (P=0.03), reported a poor/neutral experience at their first related HCP appointment (P=0.02), or were diagnosed in the public sector (P=0.01). CONCLUSIONS: Few patients initially suspected bowel cancer or reported embarrassment seeking care; those who did were most likely to experience changes in bowel habit or bleeding. Our study is small, and not representative of all those diagnosed with CRC in New Zealand; yet it provides important first insights into patients' diagnostic experiences. PMID- 30286064 TI - Alcohol-related emergency department attendances after the introduction of the Sale and Supply of Alcohol Act 2012. AB - AIM: To measure changes in alcohol-related emergency department (ED) attendances after introduction of the Sale and Supply of Alcohol Act 2012. METHODS: Cross sectional survey of Christchurch ED attendees in three-week sampling periods in 2013 and 2017. Participants had consumed alcohol within four hours, or their drinking had directly contributed to the attendance. The quantity of alcohol consumed and places of purchase and consumption for the index drinking episode were recorded. RESULTS: From 2013 to 2017 there was a non-significant (p=.41) reduction in the proportion of ED attendees eligible for the study, from 253/3400 (7.4%) to 258/3721 (6.9%). Among participants (n=169 in 2013, n=139 in 2017), liquor store purchasing increased from 41.7% in 2013 to 56.1% in 2017 (p<.01) but there was no significant change in quantity consumed in the index episode; last drink location; percentage of participants with an injury-related attendance; or pre-drinking. In both waves, most participants had purchased alcohol from off licence venues and consumed their last drink at a private location. CONCLUSION: Alcohol-related ED attendances remained common after the Sale and Supply of Alcohol Act 2012 was introduced, and they mainly occurred in people who sourced alcohol from off-licence outlets and had their last drink at private locations. PMID- 30286065 TI - Equine-related injuries requiring hospitalisation in the Midland Region of New Zealand: a continuous five-year review. AB - AIM: To examine the pattern and outcomes of equine-related injuries for hospitalised patients in the Midland Region of New Zealand over a five-year period. METHOD: A retrospective review of all patients admitted to hospitals within the Midland region of New Zealand with an injury date 1 January 2012-31 December 2016, as a direct result of equine-related trauma. RESULTS: Seven hundred and one patients were admitted due to equine-related injuries, 6.6% were major trauma events (Injury Severity Scale >12), with nearly half of all injuries (47.3%) to the extremities. Mean age was 36 years (median 38 years), and 69% were females. The most common mechanisms of injury were falls from horse (70.6%), kicked (12.7%) and knocked (6.7%) by the horse. Males were more likely to have a non-fall injury. Average length of stay (all patients) was 3.4 days, and half of all patients required surgery. All patients survived. At Waikato Hospital, the largest district hospital in the region, the average inpatient cost was NZ$7,805/patient. CONCLUSION: The study has identified the demography, injury types, risk factors and outcomes for equine-related injuries in the Midland Region of New Zealand. Indications are that the severity of such injuries may be less than previously reported. However, the volumes and costs of injury represent a significant burden on the health system, individuals and communities. More detailed understanding of causative factors will allow targeting of prevention strategies to address high-risk activities and demographic groups. PMID- 30286066 TI - Conflict of interest and alcohol discourse-a new face but familiar messages. AB - The launch of a new alcohol industry body, the Alcohol Beverages Council, provides an active voice in the media debate on alcohol policy in New Zealand. The Council's messages are the usual ones offered by the alcohol industry: a focus on the drinker, not the product; protection of the rights of the moderate drinker; arguments for education; and erroneous statements about evidence-based policies. At the global level these messages, in the context of corporate social responsibility and lobbying activities, have been successful in subverting effective policy. A similar lack of policy implementation has happened in New Zealand. Underpinning the industry lobbying is the need to protect their sales and profits, 46% of which, in New Zealand, are derived from very heavy alcohol consumption. It is important policy makers and media recognise the conflict of interest inherent in these messages. PMID- 30286067 TI - Colloidal silver optic neuropathy.

PMID- 30286069 TI - The fault in his seeds: Lost notes to the case of bias in Samuel George Morton's cranial race science. AB - The discovery of nearly 180-year-old cranial measurements in the archives of 19th century American physician and naturalist Samuel George Morton can address a lingering debate, begun in the late 20th century by paleontologist and historian of science Stephen Jay Gould, about the unconscious bias alleged in Morton's comparative data of brain size in human racial groups. Analysis of Morton's lost data and the records of his studies does not support Gould's arguments about Morton's biased data collection. However, historical contextualization of Morton with his scientific peers, especially German anatomist Friedrich Tiedemann, suggests that, while Morton's data may have been unbiased, his cranial race science was not. Tiedemann and Morton independently produced similar data about human brain size in different racial groups but analyzed and interpreted their nearly equivalent results in dramatically different ways: Tiedemann using them to argue for equality and the abolition of slavery, and Morton using them to entrench racial divisions and hierarchy. These differences draw attention to the epistemic limitations of data and the pervasive role of bias within the broader historical, social, and cultural context of science.

PMID- 30286071 TI - A systems biology approach uncovers the core gene regulatory network governing iridophore fate choice from the neural crest. AB - Multipotent neural crest (NC) progenitors generate an astonishing array of derivatives, including neuronal, skeletal components and pigment cells (chromatophores), but the molecular mechanisms allowing balanced selection of each fate remain unknown. In zebrafish, melanocytes, iridophores and xanthophores, the three chromatophore lineages, are thought to share progenitors and so lend themselves to investigating the complex gene regulatory networks (GRNs) underlying fate segregation of NC progenitors. Although the core GRN governing melanocyte specification has been previously established, those guiding iridophore and xanthophore development remain elusive. Here we focus on the iridophore GRN, where mutant phenotypes identify the transcription factors Sox10, Tfec and Mitfa and the receptor tyrosine kinase, Ltk, as key players. Here we present expression data, as well as loss and gain of function results, guiding the derivation of an initial iridophore specification GRN. Moreover, we use an iterative process of mathematical modelling, supplemented with a Monte Carlo screening algorithm suited to the qualitative nature of the experimental data, to allow for rigorous predictive exploration of the GRN dynamics. Predictions were experimentally evaluated and testable hypotheses were derived to construct an improved version of the GRN, which we showed produced outputs consistent with experimentally observed gene expression dynamics. Our study reveals multiple important regulatory features, notably a sox10-dependent positive feedback loop between tfec and ltk driving iridophore specification; the molecular basis of sox10 maintenance throughout iridophore development; and the cooperation between sox10 and tfec in driving expression of pnp4a, a key differentiation gene. We also assess a candidate repressor of mitfa, a melanocyte-specific target of sox10. Surprisingly, our data challenge the reported role of Foxd3, an established mitfa repressor, in iridophore regulation. Our study builds upon our previous systems biology approach, by incorporating physiologically-relevant parameter values and rigorous evaluation of parameter values within a qualitative data framework, to establish for the first time the core GRN guiding specification of the iridophore lineage. PMID- 30286073 TI - A Kirchhoff-Nernst-Planck framework for modeling large scale extracellular electrodiffusion surrounding morphologically detailed neurons. AB - Many pathological conditions, such as seizures, stroke, and spreading depression, are associated with substantial changes in ion concentrations in the extracellular space (ECS) of the brain. An understanding of the mechanisms that govern ECS concentration dynamics may be a prerequisite for understanding such pathologies. To estimate the transport of ions due to electrodiffusive effects, one must keep track of both the ion concentrations and the electric potential simultaneously in the relevant regions of the brain. Although this is currently unfeasible experimentally, it is in principle achievable with computational models based on biophysical principles and constraints. Previous computational models of extracellular ion-concentration dynamics have required extensive computing power, and therefore have been limited to either phenomena on very small spatiotemporal scales (micrometers and milliseconds), or simplified and idealized 1-dimensional (1-D) transport processes on a larger scale. Here, we present the 3-D Kirchhoff-Nernst-Planck (KNP) framework, tailored to explore electrodiffusive effects on large spatiotemporal scales. By assuming electroneutrality, the KNP-framework circumvents charge-relaxation processes on the spatiotemporal scales of nanometers and nanoseconds, and makes it feasible to run simulations on the spatiotemporal scales of millimeters and seconds on a standard desktop computer. In the present work, we use the 3-D KNP framework to simulate the dynamics of ion concentrations and the electrical potential surrounding a morphologically detailed pyramidal cell. In addition to elucidating the single neuron contribution to electrodiffusive effects in the ECS, the simulation demonstrates the efficiency of the 3-D KNP framework. We envision that future applications of the framework to more complex and biologically realistic systems will be useful in exploring pathological conditions associated with large concentration variations in the ECS. PMID- 30286074 TI - Rhinoceros beetle horn development reveals deep parallels with dung beetles. AB - Beetle horns are attractive models for studying the evolution of novel traits, as they display diverse shapes, sizes, and numbers among closely related species within the family Scarabaeidae. Horns radiated prolifically and independently in two distant subfamilies of scarabs, the dung beetles (Scarabaeinae), and the rhinoceros beetles (Dynastinae). However, current knowledge of the mechanisms underlying horn diversification remains limited to a single genus of dung beetles, Onthophagus. Here we unveil 11 horn formation genes in a rhinoceros beetle, Trypoxylus dichotomus. These 11 genes are mostly categorized as larval head- and appendage-patterning genes that also are involved in Onthophagus horn formation, suggesting the same suite of genes was recruited in each lineage during horn evolution. Although our RNAi analyses reveal interesting differences in the functions of a few of these genes, the overwhelming conclusion is that both head and thoracic horns develop similarly in Trypoxylus and Onthophagus, originating in the same developmental regions and deploying similar portions of appendage patterning networks during their growth. Our findings highlight deep parallels in the development of rhinoceros and dung beetle horns, suggesting either that both horn types arose in the common ancestor of all scarabs, a surprising reconstruction of horn evolution that would mean the majority of scarab species (~35,000) actively repress horn growth, or that parallel origins of these extravagant structures resulted from repeated co-option of the same underlying developmental processes. PMID- 30286075 TI - Engineered nanoparticles bind elapid snake venom toxins and inhibit venom-induced dermonecrosis. AB - Envenomings by snakebites constitute a serious and challenging global health issue. The mainstay in the therapy of snakebite envenomings is the parenteral administration of animal-derived antivenoms. Significantly, antivenoms are only partially effective in the control of local tissue damage. A novel approach to mitigate the progression of local tissue damage that could complement the antivenom therapy of envenomings is proposed. We describe an abiotic hydrogel nanoparticle engineered to bind to and modulate the activity of a diverse array of PLA2 and 3FTX isoforms found in Elapidae snake venoms. These two families of protein toxins share features that are associated with their common (membrane) targets, allowing for nanoparticle sequestration by a mechanism that differs from immunological (epitope) selection. The nanoparticles are non-toxic in mice and inhibit dose-dependently the dermonecrotic activity of Naja nigricollis venom. PMID- 30286076 TI - Community-based prevalence of typhoid fever, typhus, brucellosis and malaria among symptomatic individuals in Afar Region, Ethiopia. AB - BACKGROUND: In sub-Saharan Africa, where there is the scarcity of proper diagnostic tools, febrile illness related symptoms are often misdiagnosed as malaria. Information on causative agents of febrile illness related symptoms among pastoral communities in Ethiopia have rarely been described. METHODS: In this a community based cross-sectional survey, we assessed the prevalence of typhoid fever, typhus, brucellosis and malaria among individuals with a set of given symptoms in Amibara district, Afar Region, Ethiopia. Blood samples were collected from 650 study participants, and examined by Widal and Weilfelix direct card agglutination test (DCAT) as well as test tube based titration test for Salmonella enterica serotype Typhi (S. Typhi) and Rickettsia infections. Rose Bengal Plate Test (RBPT) and Complement Fixation Test (CFT) were used to screen Brucella infection. Thin and thick blood smears were used to diagnosis malaria. RESULTS: Out of 630 sera screened by DCAT, 83 (13.2%) were reactive to H and/or O antigens for S. Typhi infection. Among these, 46 (55.4%) were reactive by the titration test at the cut off value >= 1:80. The combined sero-prevalence for S. Typhi by the two tests was 7.3% (46/630). The seroprevalence for Rickettsia infection was 26.2% (165/630) by DCAT and 53.3% (88/165) by the titration test at the cut off value >= 1:80. The combined sero-prevalence for Rickettsia infection by the two tests was 14.0% (88/630). The sero-prevalence for Brucella infection was 12.7% (80/630) by RBPT, of which 28/80 (35%) were positive by CFT. The combined sero-prevalence for Brucella infection by the two tests was 4.4% (28/630). Out 650 suspected individuals for malaria, 16 (2.5%) were found positive for P. falciparum infection. CONCLUSION: In this study, typhoid fever, typhus, brucellosis and malaria were observed among symptomatic individuals. The study also highlighted that brucellosis cases can be misdiagnosed as malaria or other disease based solely on clinical diagnosis. Therefore, efforts are needed to improve disease awareness and laboratory services for the diagnosis of brucellosis and other zoonotic diseases to identify other causes of febrile illness in this pastoral setting. PMID- 30286077 TI - Prediction of gene regulatory enhancers across species reveals evolutionarily conserved sequence properties. AB - Genomic regions with gene regulatory enhancer activity turnover rapidly across mammals. In contrast, gene expression patterns and transcription factor binding preferences are largely conserved between mammalian species. Based on this conservation, we hypothesized that enhancers active in different mammals would exhibit conserved sequence patterns in spite of their different genomic locations. To investigate this hypothesis, we evaluated the extent to which sequence patterns that are predictive of enhancers in one species are predictive of enhancers in other mammalian species by training and testing two types of machine learning models. We trained support vector machine (SVM) and convolutional neural network (CNN) classifiers to distinguish enhancers defined by histone marks from the genomic background based on DNA sequence patterns in human, macaque, mouse, dog, cow, and opossum. The classifiers accurately identified many adult liver, developing limb, and developing brain enhancers, and the CNNs outperformed the SVMs. Furthermore, classifiers trained in one species and tested in another performed nearly as well as classifiers trained and tested on the same species. We observed similar cross-species conservation when applying the models to human and mouse enhancers validated in transgenic assays. This indicates that many short sequence patterns predictive of enhancers are largely conserved. The sequence patterns most predictive of enhancers in each species matched the binding motifs for a common set of TFs enriched for expression in relevant tissues, supporting the biological relevance of the learned features. Thus, despite the rapid change of active enhancer locations between mammals, cross-species enhancer prediction is often possible. Our results suggest that short sequence patterns encoding enhancer activity have been maintained across more than 180 million years of mammalian evolution.

PMID- 30286080 TI - Association between ambient air pollution and daily hospital admissions for ischemic stroke: A nationwide time-series analysis. AB - BACKGROUND: Evidence of the short-term effects of ambient air pollution on the risk of ischemic stroke in low- and middle-income countries is limited and inconsistent. We aimed to examine the associations between air pollution and daily hospital admissions for ischemic stroke in China. METHODS AND FINDINGS: We identified hospital admissions for ischemic stroke in 2014-2016 from the national database covering up to 0.28 billion people who received Urban Employee Basic Medical Insurance (UEBMI) in China. We examined the associations between air pollution and daily ischemic stroke admission using a two-stage method. Poisson time-series regression models were firstly fitted to estimate the effects of air pollution in each city. Random-effects meta-analyses were then conducted to combine the estimates. Meta-regression models were applied to explore potential effect modifiers. More than 2 million hospital admissions for ischemic stroke were identified in 172 cities in China. In single-pollutant models, increases of 10 MUg/m3 in particulate matter with aerodynamic diameter <2.5 MUm (PM2.5), sulfur dioxide (SO2), nitrogen dioxide (NO2), and ozone (O3) and 1 mg/m3 in carbon monoxide (CO) concentrations were associated with 0.34% (95% confidence interval [CI], 0.20%-0.48%), 1.37% (1.05%-1.70%), 1.82% (1.45%-2.19%), 0.01% ( 0.14%-0.16%), and 3.24% (2.05%-4.43%) increases in hospital admissions for ischemic stroke on the same day, respectively. SO2 and NO2 associations remained significant in two-pollutant models, but not PM2.5 and CO associations. The effect estimates were greater in cities with lower air pollutant levels and higher air temperatures, as well as in elderly subgroups. The main limitation of the present study was the unavailability of data on individual exposure to ambient air pollution. CONCLUSIONS: As the first national study in China to systematically examine the associations between short-term exposure to ambient air pollution and ischemic stroke, our findings indicate that transient increase in air pollution levels may increase the risk of ischemic stroke, which may have significant public health implications for the reduction of ischemic stroke burden in China. PMID- 30286079 TI - GABAergic modulation of olfactomotor transmission in lampreys. AB - Odor-guided behaviors, including homing, predator avoidance, or food and mate searching, are ubiquitous in animals. It is only recently that the neural substrate underlying olfactomotor behaviors in vertebrates was uncovered in lampreys. It consists of a neural pathway extending from the medial part of the olfactory bulb (medOB) to locomotor control centers in the brainstem via a single relay in the caudal diencephalon. This hardwired olfactomotor pathway is present throughout life and may be responsible for the olfactory-induced motor behaviors seen at all life stages. We investigated modulatory mechanisms acting on this pathway by conducting anatomical (tract tracing and immunohistochemistry) and physiological (intracellular recordings and calcium imaging) experiments on lamprey brain preparations. We show that the GABAergic circuitry of the olfactory bulb (OB) acts as a gatekeeper of this hardwired sensorimotor pathway. We also demonstrate the presence of a novel olfactomotor pathway that originates in the non-medOB and consists of a projection to the lateral pallium (LPal) that, in turn, projects to the caudal diencephalon and to the mesencephalic locomotor region (MLR). Our results indicate that olfactory inputs can induce behavioral responses by activating brain locomotor centers via two distinct pathways that are strongly modulated by GABA in the OB. The existence of segregated olfactory subsystems in lampreys suggests that the organization of the olfactory system in functional clusters may be a common ancestral trait of vertebrates. PMID- 30286082 TI - Direct-to-consumer DNA testing of 6,000 dogs reveals 98.6-kb duplication associated with blue eyes and heterochromia in Siberian Huskies. AB - Consumer genomics enables genetic discovery on an unprecedented scale by linking very large databases of personal genomic data with phenotype information voluntarily submitted via web-based surveys. These databases are having a transformative effect on human genomics research, yielding insights on increasingly complex traits, behaviors, and disease by including many thousands of individuals in genome-wide association studies (GWAS). The promise of consumer genomic data is not limited to human research, however. Genomic tools for dogs are readily available, with hundreds of causal Mendelian variants already characterized, because selection and breeding have led to dramatic phenotypic diversity underlain by a simple genetic structure. Here, we report the results of the first consumer genomics study ever conducted in a non-human model: a GWAS of blue eyes based on more than 3,000 customer dogs with validation panels including nearly 3,000 more, the largest canine GWAS to date. We discovered a novel association with blue eyes on chromosome 18 (P = 1.3x10-68) and used both sequence coverage and microarray probe intensity data to identify the putative causal variant: a 98.6-kb duplication directly upstream of the Homeobox gene ALX4, which plays an important role in mammalian eye development. This duplication is largely restricted to Siberian Huskies, is strongly associated with the blue-eyed phenotype (chi-square P = 5.2x10-290), and is highly, but not completely, penetrant. These results underscore the power of consumer-data-driven discovery in non-human species, especially dogs, where there is intense owner interest in the personal genomic information of their pets, a high level of engagement with web-based surveys, and an underlying genetic architecture ideal for mapping studies. PMID- 30286078 TI - FoxO6 regulates Hippo signaling and growth of the craniofacial complex. AB - The mechanisms that regulate post-natal growth of the craniofacial complex and that ultimately determine the size and shape of our faces are not well understood. Hippo signaling is a general mechanism to control tissue growth and organ size, and although it is known that Hippo signaling functions in neural crest specification and patterning during embryogenesis and before birth, its specific role in postnatal craniofacial growth remains elusive. We have identified the transcription factor FoxO6 as an activator of Hippo signaling regulating neonatal growth of the face. During late stages of mouse development, FoxO6 is expressed specifically in craniofacial tissues and FoxO6-/- mice undergo expansion of the face, frontal cortex, olfactory component and skull. Enlargement of the mandible and maxilla and lengthening of the incisors in FoxO6-/- mice are associated with increases in cell proliferation. In vitro and in vivo studies demonstrated that FoxO6 activates Lats1 expression, thereby increasing Yap phosphorylation and activation of Hippo signaling. FoxO6-/- mice have significantly reduced Hippo Signaling caused by a decrease in Lats1 expression and decreases in Shh and Runx2 expression, suggesting that Shh and Runx2 are also linked to Hippo signaling. In vitro, FoxO6 activates Hippo reporter constructs and regulates cell proliferation. Furthermore PITX2, a regulator of Hippo signaling is associated with Axenfeld-Rieger Syndrome causing a flattened midface and we show that PITX2 activates FoxO6 expression. Craniofacial specific expression of FoxO6 postnatally regulates Hippo signaling and cell proliferation. Together, these results identify a FoxO6-Hippo regulatory pathway that controls skull growth, odontogenesis and face morphology. PMID- 30286083 TI - INDUCER OF CBF EXPRESSION 1 is a male fertility regulator impacting anther dehydration in Arabidopsis. AB - INDUCER OF CBF EXPRESSION 1 (ICE1) encodes a MYC-like basic helix-loop-helix (bHLH) transcription factor playing a critical role in plant responses to chilling and freezing stresses and leaf stomata development. However, no information connecting ICE1 and reproductive development has been reported. In this study, we show that ICE1 controls plant male fertility via impacting anther dehydration. The loss-of-function mutation in ICE1 gene in Arabidopsis caused anther indehiscence and decreased pollen viability as well as germination rate. Further analysis revealed that the anthers in the mutant of ICE1 (ice1-2) had the structure of stomium, though the epidermis did not shrink to dehisce. The anther indehiscence and influenced pollen viability as well as germination in ice1-2 were due to abnormal anther dehydration, for most of anthers dehisced with drought treatment and pollen grains from those dehydrated anthers had similar viability and germination rates compared with wild type. Accordingly, the sterility of ice1-2 could be rescued by ambient dehydration treatments. Likewise, the stomatal differentiation of ice1-2 anther epidermis was disrupted in a different manner compared with that in leaves. ICE1 specifically bound to MYC recognition elements in the promoter of FAMA, a key regulator of guard cell differentiation, to activate FAMA expression. Transcriptome profiling in the anther tissues further exhibited ICE1-modulated genes associated with water transport and ion exchange in the anther. Together, this work reveals the key role of ICE1 in male fertility control and establishes a regulatory network mediated by ICE1 for stomata development and water movement in the anther. PMID- 30286084 TI - Population genetic analysis of Chadian Guinea worms reveals that human and non human hosts share common parasite populations. AB - Following almost 10 years of no reported cases, Guinea worm disease (GWD or dracunculiasis) reemerged in Chad in 2010 with peculiar epidemiological patterns and unprecedented prevalence of infection among non-human hosts, particularly domestic dogs. Since 2014, animal infections with Guinea worms have also been observed in the other three countries with endemic transmission (Ethiopia, Mali, and South Sudan), causing concern and generating interest in the parasites' true taxonomic identity and population genetics. We present the first extensive population genetic data for Guinea worm, investigating mitochondrial and microsatellite variation in adult female worms from both human and non-human hosts in the four endemic countries to elucidate the origins of Chad's current outbreak and possible host-specific differences between parasites. Genetic diversity of Chadian Guinea worms was considerably higher than that of the other three countries, even after controlling for sample size through rarefaction, and demographic analyses are consistent with a large, stable parasite population. Genealogical analyses eliminate the other three countries as possible sources of parasite reintroduction into Chad, and sequence divergence and distribution of genetic variation provide no evidence that parasites in human and non-human hosts are separate species or maintain isolated transmission cycles. Both among and within countries, geographic origin appears to have more influence on parasite population structure than host species. Guinea worm infection in non-human hosts has been occasionally reported throughout the history of the disease, particularly when elimination programs appear to be reaching their end goals. However, no previous reports have evaluated molecular support of the parasite species identity. Our data confirm that Guinea worms collected from non-human hosts in the remaining endemic countries of Africa are Dracunculus medinensis and that the same population of worms infects both humans and dogs in Chad. Our genetic data and the epidemiological evidence suggest that transmission in the Chadian context is currently being maintained by canine hosts. PMID- 30286086 TI - Dengue illness index-A tool to characterize the subjective dengue illness experience. AB - Dengue virus infections are a major cause of febrile illness that significantly affects individual and societal productivity and drives up health care costs principally in the developing world. Two dengue vaccine candidates are in advanced clinical efficacy trials in Latin America and Asia, and another has been licensed in more than fifteen countries but its uptake has been limited. Despite these advances, standardized metrics for comparability of protective efficacy between dengue vaccines remain poorly defined. The Dengue Illness Index (DII) is a tool that we developed thru refinement of previous similar iterations in an attempt to improve and standardize the measurement of vaccine and drug efficacy in reducing moderate dengue illness. The tool is designed to capture an individual's overall disease experience based on how the totality of their symptoms impacts their general wellness and daily functionality. We applied the DII to a diary card, the Dengue Illness Card (DIC), which was examined and further developed by a working group. The card was then refined with feedback garnered from a Delphi methodology-based query that addressed the adequacy and applicability of the tool in clinical dengue research. There was overall agreement that the tool would generate useful data and provide an alternative perspective to the assessment of drug or vaccine candidates, which in the case of vaccines, are assessed by their reduction in any virologically confirmed dengue of any severity with a focus on the more severe. The DIC needs to be evaluated in the field in the context of vaccine or drug trials, prospective cohort studies, or during experimental human infection studies. Here, we present the final DIC resulting from the Delphi process and offer its further development or use to the dengue research community. PMID- 30286085 TI - Development of standard clinical endpoints for use in dengue interventional trials. AB - Dengue is a major public health problem worldwide. Although several drug candidates have been evaluated in randomized controlled trials, none has been effective and at present, early recognition of severe dengue and timely supportive care are used to reduce mortality. While the first dengue vaccine was recently licensed, and several other candidates are in late stage clinical trials, future decisions regarding widespread deployment of vaccines and/or therapeutics will require evidence of product safety, efficacy and effectiveness. Standard, quantifiable clinical endpoints are needed to ensure reproducibility and comparability of research findings. To address this need, we established a working group of dengue researchers and public health specialists to develop standardized endpoints and work towards consensus opinion on those endpoints. After discussion at two working group meetings and presentations at international conferences, a Delphi methodology-based query was used to finalize and operationalize the clinical endpoints. Participants were asked to select the best endpoints from proposed definitions or offer revised/new definitions, and to indicate whether contributing items should be designated as optional or required. After the third round of inquiry, 70% or greater agreement was reached on moderate and severe plasma leakage, moderate and severe bleeding, acute hepatitis and acute liver failure, and moderate and severe neurologic disease. There was less agreement regarding moderate and severe thrombocytopenia and moderate and severe myocarditis. Notably, 68% of participants agreed that a 50,000 to 20,000 mm3 platelet range be used to define moderate thrombocytopenia; however, they remained divided on whether a rapid decreasing trend or one platelet count should be case defining. While at least 70% agreement was reached on most endpoints, the process identified areas for further evaluation and standardization within the context of ongoing clinical studies. These endpoints can be used to harmonize data collection and improve comparability between dengue clinical trials.

AB - INTRODUCTION: Human immunodeficiency virus and protein energy malnutrition are still prevalent in Nigeria and the occurrence of the two conditions together confers a poor prognosis. The aim of this study was to determine the current categories of malnutrition amongst under-5 children in Lagos, document their HIV status and determine any peculiarities in the clinical features, haematological and some biochemical profile in these children. METHODS: The study was a cross sectional study conducted at the Paediatric departments of the Lagos University Teaching Hospital and the Massey Street Children's Hospital, both in Lagos, over a 6-month period. All the subjects had anthropometry, HIV testing, full blood count and serum proteins done. The factors associated with HIV status were determined with the logistic regression analysis. RESULTS: Two hundred and fourteen (214) malnourished children <=5 years, including 25 (11.7%) with HIV were recruited in the study. Among the study participants, 150 (70.1%) and 54 (29.9%) had moderate and severe malnutrition, respectively. Fever, cough and diarrhea were the most common symptoms in the study participants. The haematological indices were comparable in the two groups, the serum globulin levels though higher in the HIV infected group was not statistically significantly different from the non-infected group.(p = 0.66). None of the factors explored on multivariate analysis was able to predict the occurrence of the infection in this cohort. CONCLUSION: Malnourished children remain a high risk group for HIV infection and the prevalence of the infection obtained in this group of children is still unacceptably high. Discriminatory features between malnutrition and HIV remains difficult. The presence of hyperglobulinaemia on laboratory analysis in a malnourished child may heighten the suspicion of possible underlying associated HIV infection. Screening of malnourished children for HIV infection and further longitudinal studies on malnourished children with HIV is advocated. PMID- 30286088 TI - Integrated analysis of DNA methylation profiling and gene expression profiling identifies novel markers in lung cancer in Xuanwei, China. AB - BACKGROUND: Aberrant DNA methylation occurs frequently in cancer. The aim of this study was to identify novel methylation markers in lung cancer in Xuanwei, China, through integrated genome-wide DNA methylation and gene expression studies. METHODS: Differentially methylated regions (DMRs) and differentially expressed genes (DEGs) were detected on 10 paired lung cancer tissues and noncancerous lung tissues by methylated DNA immunoprecipitation combined with microarray (MeDIP chip) and gene expression microarray analyses, respectively. Integrated analysis of DMRs and DEGs was performed to screen out candidate methylation-related genes. Both methylation and expression changes of the candidate genes were further validated and analyzed. RESULTS: Compared with normal lung tissues, lung cancer tissues expressed a total of 6,899 DMRs, including 5,788 hypermethylated regions and 1,111 hypomethylated regions. Integrated analysis of DMRs and DEGs identified 45 tumor-specific candidate genes: 38 genes whose DMRs were hypermethylated and expression was downregulated, and 7 genes whose DMRs were hypomethylated and expression was upregulated. The methylation and expression validation results identified 4 candidate genes (STXBP6, BCL6B, FZD10, and HSPB6) that were significantly hypermethylated and downregulated in most of the tumor tissues compared with the noncancerous lung tissues. CONCLUSIONS: This integrated analysis of genome-wide DNA methylation and gene expression in lung cancer in Xuanwei revealed several genes regulated by promoter methylation that have not been described in lung cancer before. These results provide new insight into the carcinogenesis of lung cancer in Xuanwei and represent promising new diagnostic and therapeutic targets. PMID- 30286089 TI - Mitigating the impact of microbial pressure on great (Parus major) and blue (Cyanistes caeruleus) tit hatching success through maternal immune investment. AB - The hatching success of a bird's egg is one of the key determinants of avian reproductive success, which may be compromised by microbial infections causing embryonic death. During incubation, outer eggshell bacterial communities pose a constant threat of pathogen translocation and embryo infection. One of the parental strategies to mitigate this threat is the incorporation of maternal immune factors into the egg albumen and yolk. It has been suggested that habitat changes like forest fragmentation can affect environmental factors and life history traits that are linked to egg contamination. This study aims at investigating relationships between microbial pressure, immune investment and hatching success in two abundant forest bird species and analyzing to what extent these are driven by extrinsic (environmental) factors. We here compared (1) the bacterial load and composition on eggshells, (2) the level of immune defenses in eggs, and (3) the reproductive success between great (Parus major) and blue (Cyanistes caeruleus) tits in Belgium and examined if forest fragmentation affects these parameters. Analysis of 70 great tit and 34 blue tit eggshells revealed a similar microbiota composition (Enterobacteriaceae, Lactobacillus spp., Firmicutes and Bacteroidetes), but higher bacterial loads in great tits. Forest fragmentation was not identified as an important explanatory variable. Although a significant negative correlation between hatching success and bacterial load on the eggshells in great tits corroborates microbial pressure to be a driver of embryonic mortality, the overall hatching success was only marginally lower than in blue tits. This may be explained by the significantly higher levels of lysozyme and IgY in the eggs of great tits, protecting the embryo from increased infection pressure. Our results show that immune investment in eggs is suggested to be a species-specific adaptive trait that serves to protect hatchlings from pathogen pressure, which is not directly linked to habitat fragmentation. PMID- 30286090 TI - Gender and household structure factors associated with maternal and child undernutrition in rural communities in Ethiopia. AB - Addressing maternal and child undernutrition is a priority for the National Nutrition Program of Ethiopia. In a cross-sectional design, we selected mother child pairs (n = 630) from Halaba, south Ethiopia (n = 413, two communities) and Zeway, Oromiya region (n = 217, one community). These communities were previously included in a project to improve agricultural practices. We aimed to estimate the level of maternal and child undernutrition in the two study sites and compare findings to regional/national reports. We also examined associations with gender, household-structure and nutrition/health related variables. Households were selected using simple random sampling based on list of households obtained from local health posts. Mothers were interviewed via questionnaire. Anthropometric measurements were taken from mothers-child pairs. Maternal undernutrition (% BMI<18.5) ranged from moderate (14% Zeway) to high (22% Halaba). In the children, stunting and underweight were very high (54% and 42% stunting, 36% and 21% underweight, in Halaba and Zeway, respectively). Up to 95% of Halaba and 85% of Zeway mothers reported "same as usual" or "less than usual" consumption patterns during their most recent pregnancy compared to periods of non-pregnancy. Mothers reported (61% in Halaba, 18% in Zeway) abstaining from consumption of certain nutritious foods for cultural reasons. Gender and socio-economic-demographic structure of the households, including imbalance of power, control of farm produce, physiological density, household size and dietary habits during pregnancy showed significant associations with maternal and child undernutrition (p<0.05). The levels of child and maternal undernutrition, particularly in children, were unexpected and of concern, given that a national nutrition program has been in place since 2008. The study provides insights for policy makers to improve women's education, reproductive health services for better family planning, and strengthen nutrition/health programs designed to target vulnerable segments of the population in these and other rural communities and districts with similar structure and demographics in Ethiopia. PMID- 30286092 TI - Representation effects in the centipede game. AB - We explore the effects on strategic behavior of alternative representations of a centipede game that differ in terms of complexity. In a laboratory experiment, we manipulate the way in which payoffs are presented to subjects in two different ways. In both cases, information is made less accessible relative to the standard representation of the game. Results show that these manipulations shift the distribution of take nodes further away from the equilibrium prediction. The evidence is consistent with the view that failures of game-form recognition and the resulting limits to strategic reasoning are crucial for explaining non equilibrium behavior in the centipede game. PMID- 30286091 TI - Feedbacks from the metabolic network to the genetic network reveal regulatory modules in E. coli and B. subtilis. AB - The genetic regulatory network (GRN) plays a key role in controlling the response of the cell to changes in the environment. Although the structure of GRNs has been the subject of many studies, their large scale structure in the light of feedbacks from the metabolic network (MN) has received relatively little attention. Here we study the causal structure of the GRNs, namely the chain of influence of one component on the other, taking into account feedback from the MN. First we consider the GRNs of E. coli and B. subtilis without feedback from MN and illustrate their causal structure. Next we augment the GRNs with feedback from their respective MNs by including (a) links from genes coding for enzymes to metabolites produced or consumed in reactions catalyzed by those enzymes and (b) links from metabolites to genes coding for transcription factors whose transcriptional activity the metabolites alter by binding to them. We find that the inclusion of feedback from MN into GRN significantly affects its causal structure, in particular the number of levels and relative positions of nodes in the hierarchy, and the number and size of the strongly connected components (SCCs). We then study the functional significance of the SCCs. For this we identify condition specific feedbacks from the MN into the GRN by retaining only those enzymes that are essential for growth in specific environmental conditions simulated via the technique of flux balance analysis (FBA). We find that the SCCs of the GRN augmented by these feedbacks can be ascribed specific functional roles in the organism. Our algorithmic approach thus reveals relatively autonomous subsystems with specific functionality, or regulatory modules in the organism. This automated approach could be useful in identifying biologically relevant modules in other organisms for which network data is available, but whose biology is less well studied. PMID- 30286093 TI - High-fat diet suppresses the positive effect of creatine supplementation on skeletal muscle function by reducing protein expression of IGF-PI3K-AKT-mTOR pathway. AB - High-fat (HF) diets in combination with sedentary lifestyle represent one of the major public health concerns predisposing to obesity and diabetes leading to skeletal muscle atrophy, decreased fiber diameter and muscle mass with accumulation of fat tissue resulting in loss of muscle strength. One strategy to overcome the maleficent effects of HF diet is resistance training, a strategy used to improve muscle mass, reverting the negative effects on obesity-related changes in skeletal muscle. Together with resistance training, supplementation with creatine monohydrate (CrM) in the diet has been used to improve muscle mass and strength. Creatine is a non-essential amino acid that is directly involved in the cross-bridge cycle providing a phosphate group to ADP during the initiation of muscle contraction. Besides its antioxidant and anti-inflammatory effects CrM also upregulates IGF-1 resulting in hyperthophy with an increase in muscle function. However, it is unknown whether CrM supplementation during resistance training would revert the negative effects of high-fat diet on the muscle performance. During 8 weeks we measured muscle performance to climb a 1.1m and 80 degrees ladder with increasing load on trained rats that had received standard diet or high-fat diet, supplemented or not with CrM. We observed that the CrM supplementation up-regulated IGF-1 and phospho-AKT protein levels, suggesting an activation of the IGF1-PI3K-Akt/PKB-mTOR pathway. Moreover, despite the CrM supplementation, HF diet down-regulated several proteins of the IGF1-PI3K-Akt/PKB mTOR pathway, suggesting that diet lipid content is crucial to maintain or improve muscle function during resistance training. PMID- 30286094 TI - Assessing the pedestrian response to urban outdoor lighting: A full-scale laboratory study. AB - This study identifies and applies methods for evaluating the human response to pedestrian lighting applications intended for future use by the municipality of Malmo, Sweden. The methods employed provide a supplementary perspective to that given by the photometric properties of the lighting applications. The study involved 89 participants from two age groups (Young: N: 43, 19-31 yrs.; Elderly: N: 46, 62-77 yrs.). Data were collected in a full-scale laboratory using a mock up pedestrian pathway. Three lighting applications (one ceramic metal halide and two LED) were presented and the participants' behavior (walking speed), perception (ability to perform visual tasks-recognize facial expressions, detect obstacles, read street signpost), affective response, and evaluation of the lighting quality were assessed. The three lighting applications significantly differed with regard to the human response. The facial expression recognition distance, sign reading distance and the obstacle detection task, along with the evaluation of lighting quality and level of arousal, distinguished one of the LEDs (Correlated Color Temperature: 3810, Color Rendering Index: 75, Scotopic/Photopic ratio: 1.48) from the other two lighting applications-the participants performed better on the visual tasks, and the lighting was perceived as brighter, more arousing and less pleasant. Methods to capture human perception, evaluation and behavior in relation to outdoor lighting, provide a valuable perspective that should be systematically applied when municipalities consider different pedestrian lighting applications. PMID- 30286095 TI - Inter- and intra-host sequence diversity reveal the emergence of viral variants during an overwintering epidemic caused by dengue virus serotype 2 in southern Taiwan. AB - Purifying selection during dengue viral infection has been suggested as the driving force of viral evolution and the higher complexity of the intra-host quasi-species is thought to offer an adaptive advantage for arboviruses as they cycle between arthropod and vertebrate hosts. However, very few studies have been performed to investigate the viral genetic changes within (intra-host) and between (inter-host) humans in a spatio-temporal scale. Viruses of different serotypes from various countries imported to Taiwan cause annual outbreaks. During 2001-2003, two consecutive outbreaks were caused by dengue virus serotype 2 (DENV-2) and resulted in a larger-scale epidemic with more severe dengue cases in the following year. Phylogenetic analyses showed that the viruses from both events were similar and related to the 2001 DENV-2 isolate from the Philippines. We comprehensively analyzed viral sequences from representative dengue patients and identified three consensus genetic variants, group Ia, Ib and II, with different spatio-temporal population dynamics. The phylodynamic analysis suggested group Ib variants, characterized by lower genetic diversity, transmission rate, and intra-host variant numbers, might play the role of maintenance variants. The residential locations among the patients infected by group Ib variants were in the outer rim of case clusters throughout the 2001-2003 period whereas group Ia and II variants were located in the centers of case clusters, suggesting that group Ib viruses might serve as "sheltered overwintering" variants in an undefined ecological niche. Further deep sequencing of the viral envelope (E) gene directly from individual patient serum samples confirmed the emergence of variants belonging to three quasi-species (group Ia, Ib, and II) and the ancestral role of the viral variants in the latter phase of the 2001 outbreak contributed to the later, larger-scale epidemic beginning in 2002. These findings enhanced our understanding of increasing epidemic severity over time in the same epidemic area. It also highlights the importance of combining phylodynamic and deep sequencing analysis as surveillance tools for detecting dynamic changes in viral variants, particularly searching for and monitoring any specific viral subpopulation. Such subpopulations might have selection advantages in both fitness and transmissibility leading to increased epidemic severity. PMID- 30286096 TI - Profiling of circulating exosomal miRNAs in patients with Waldenstrom Macroglobulinemia. AB - Waldenstrom Macroglobulinemia (WM) is a low-grade B-cell lymphoma characterized by disease progression from IgM MGUS to asymptomatic and then symptomatic disease states. We profiled exosomes from the peripheral blood of patients with WM at different stages (30 smoldering/asymptomatic WM, 44 symptomatic WM samples and 10 healthy controls) to define their role as potential biomarkers of disease progression. In this study, we showed that circulating exosomes and their miRNA content represent unique markers of the tumor and its microenvironment. We observed similar levels of miRNAs in exosomes from patients with asymptomatic (smoldering) and symptomatic WM, suggesting that environmental and clonal changes occur in patients at early stages of disease progression before symptoms occur. Moreover, we identified a small group of miRNAs whose expression correlated directly or inversely with the disease status of patients, notably the known tumor suppressor miRNAs let-7d and the oncogene miR-21 as well as miR-192 and miR 320b. The study of these miRNAs' specific effect in WM cells could help us gain further insights on the mechanisms underlying WM pathogenesis and reveal their potential as novel therapeutic targets for this disease. PMID- 30286097 TI - Deep learning in chest radiography: Detection of findings and presence of change. AB - BACKGROUND: Deep learning (DL) based solutions have been proposed for interpretation of several imaging modalities including radiography, CT, and MR. For chest radiographs, DL algorithms have found success in the evaluation of abnormalities such as lung nodules, pulmonary tuberculosis, cystic fibrosis, pneumoconiosis, and location of peripherally inserted central catheters. Chest radiography represents the most commonly performed radiological test for a multitude of non-emergent and emergent clinical indications. This study aims to assess accuracy of deep learning (DL) algorithm for detection of abnormalities on routine frontal chest radiographs (CXR), and assessment of stability or change in findings over serial radiographs. METHODS AND FINDINGS: We processed 874 de identified frontal CXR from 724 adult patients (> 18 years) with DL (Qure AI). Scores and prediction statistics from DL were generated and recorded for the presence of pulmonary opacities, pleural effusions, hilar prominence, and enlarged cardiac silhouette. To establish a standard of reference (SOR), two thoracic radiologists assessed all CXR for these abnormalities. Four other radiologists (test radiologists), unaware of SOR and DL findings, independently assessed the presence of radiographic abnormalities. A total 724 radiographs were assessed for detection of findings. A subset of 150 radiographs with follow up examinations was used to asses change over time. Data were analyzed with receiver operating characteristics analyses and post-hoc power analysis. RESULTS: About 42% (305/ 724) CXR had no findings according to SOR; single and multiple abnormalities were seen in 23% (168/724) and 35% (251/724) of CXR. There was no statistical difference between DL and SOR for all abnormalities (p = 0.2-0.8). The area under the curve (AUC) for DL and test radiologists ranged between 0.837 0.929 and 0.693-0.923, respectively. DL had lowest AUC (0.758) for assessing changes in pulmonary opacities over follow up CXR. Presence of chest wall implanted devices negatively affected the accuracy of DL algorithm for evaluation of pulmonary and hilar abnormalities. CONCLUSIONS: DL algorithm can aid in interpretation of CXR findings and their stability over follow up CXR. However, in its present version, it is unlikely to replace radiologists due to its limited specificity for categorizing specific findings. PMID- 30286098 TI - Identification of a VapA virulence factor functional homolog in Rhodococcus equi isolates housing the pVAPB plasmid. AB - Rhodococcus equi is a facultative intracellular bacterium of macrophages and is an important pathogen of animals and immunocompromised people wherein disease results in abcessation of the lungs and other sites. Prior work has shown that the presence of the major virulence determinant, VapA, encoded on the pVAPA-type plasmid, disrupts normal phagosome development and is essential for bacterial replication within macrophages. pVAPA- type plasmids are typical of R. equi strains derived from foals while strains from pigs carry plasmids of the pVAPB type, lacking vapA, and those from humans harbor various types of plasmids including pVAPA and pVAPB. Through the creation and analysis of a series of gene deletion mutants, we found that vapK1 or vapK2 is required for optimal intracellular replication of an R. equi isolate carrying a pVAPB plasmid type. Complementation analysis of a DeltavapA R. equi strain with vapK1 or vapK2 showed the VapK proteins of the pVAPB-type plasmid could restore replication capacity to the macrophage growth-attenuated DeltavapA strain. Additionally, in contrast to the intracellular growth capabilities displayed by an equine R. equi transconjugant strain carrying a pVAPB-type plasmid, a transconjugant strain carrying a pVAPB-type plasmid deleted of vapK1 and vapK2 proved incapable of replication in equine macrophages. Cumulatively, these data indicate that VapK1 and K2 are functionally equivalent to VapA. PMID- 30286100 TI - Ten simple rules when considering retirement. PMID- 30286101 TI - Performance appraisal method for rural infrastructure construction based on public satisfaction. AB - Rural infrastructure has rather fixed users compared to urban infrastructure. This study evaluated the effect of rural infrastructure construction from the perspective of farmers. First, this study revised the American Customer Satisfaction Index (ACSI) model and selected a performance appraisal index for rural infrastructure based on this revised model. Then, the study adopted an interpretive structural model (ISM), analyzed the influence of each index factor, and developed a hierarchical directed graph. Finally, based on the mutual influence relationships among the index factors in the hierarchical directed graph, a performance appraisal analytic network process (ANP) model was established. Based on discussions with rural college students and rural households in Sichuan, China, 246 questionnaires were obtained pertaining to rural infrastructure, and an empirical analysis was conducted. The results indicated that the performance of rural infrastructure construction is not very good. In particular, the full use of infrastructure and its role in improving the environment were found to be the worst. Meanwhile, the possibility of building information transparency and the longitudinal comparison of perceived performance appraisal results were the best. The performance of rural infrastructure construction was evaluated based on the perceptions of the direct users of rural infrastructure, and the relationship between the factors and the weight was measured reasonably. The proposed method was found to be workable and the analysis results reliable and effective. PMID- 30286099 TI - Assessment of inner and outer retinal layer metrics on the Cirrus HD-OCT Platform in normal eyes. AB - PURPOSE: Ellipsoid zone (EZ) and outer retinal integrity are strongly linked to visual prognosis, but quantitative normative data is lacking. This study evaluates the EZ, outer retina, and inner retina in eyes without macular disease across a wide age spectrum. METHODS: An IRB-approved study was performed for eyes without macular pathology undergoing Spectral Domain Optical Coherence Tomography (SD-OCT) scans on the Cirrus HD-OCT system (Carl Zeiss Meditec, Oberkochen, Germany). Scans were analyzed using a previously described automated EZ mapping tool with line-by-line manual verification. Segmentation included internal limiting membrane (ILM), outer nuclear layer/Henle fiber layer complex (ONL/HFL), EZ, and the retinal pigment epithelium (RPE). The output included metrics for the inner retina (ILM-OPL/HFL), outer retina (ONL/HFL-RPE), EZ-RPE area and volume, and en face EZ mapping. EZ-RPE attenuation on en face mapping was defined as EZ RPE thickness < 20 um, and total attenuation was 0 um. Imaging parameters were assessed for the group and compared to age, sex, visual acuity and spherical equivalent. RESULTS: 167 eyes from 167 subjects were included. Mean age was 49.7 years (range 10-84 years). The mean foveal retinal thickness was 200.58 +/- 19.22 um. Mean inner retinal thickness was 21.47 +/- 13.60 um. Mean outer retinal thickness was 179.11 +/- 18.52 um. Mean EZ-RPE thickness was 50.58 +/- 6.01um. The mean EZ-RPE volume was 1.20 +/- 0.10 mm3. Mean EZ attenuation percentage per macular map area was 0.87% +/- 1.13% and mean percentage total attenuation was 0.12% +/- 0.14%. Total and inner retinal thickness metrics decreased with age. Mean outer retinal thickness increased with age. EZ-RPE parameters were unchanged with age. However, EZ attenuation was negatively correlated with age. CONCLUSION: This study provides important information for inner and outer retinal parameters. Future research on quantitative EZ integrity can utilize this data for comparison. PMID- 30286102 TI - Evolution of urban scaling: Evidence from Brazil. AB - During the last years, the new science of cities has been established as a fertile quantitative approach to systematically understand the urban phenomena. One of its main pillars is the proposition that urban systems display universal scaling behavior regarding socioeconomic, infrastructural and individual basic services variables. This paper discusses the extension of the universality proposition by testing it against a broad range of urban metrics in a developing country urban system. We present an exploration of the scaling exponents for over 60 variables for the Brazilian urban system. Estimating those exponents is challenging from the technical point of view because the Brazilian municipalities' definition follows local political criteria and does not regard characteristics of the landscape, density, and basic utilities. As Brazilian municipalities can deviate significantly from urban settlements, urban-like municipalities were selected based on a systematic density cut-off procedure and the scaling exponents were estimated for this new subset of municipalities. To validate our findings we compared the results for overlaying variables with other studies based on alternative methods. It was found that the analyzed socioeconomic variables follow a superlinear scaling relationship with the population size, and most of the infrastructure and individual basic services variables follow expected sublinear and linear scaling, respectively. However, some infrastructural and individual basic services variables deviated from their expected regimes, challenging the universality hypothesis of urban scaling. We propose that these deviations are a product of top-down decisions/policies. Our analysis spreads over a time-range of 10 years, what is not enough to draw conclusive observations, nevertheless we found hints that the scaling exponent of these variables are evolving towards the expected scaling regime, indicating that the deviations might be temporally constrained and that the urban systems might eventually reach the expected scaling regime. PMID- 30286103 TI - Is there such a thing as a 'lope' dope? Analysis of loperamide-related European Medicines Agency (EMA) pharmacovigilance database reports. AB - BACKGROUND: Among over-the-counter (OTC) drugs, loperamide has recently emerged for its potential of misuse and cardiotoxicity issues. Hence, we aimed here at assessing the loperamide-related cases being reported to the EMA's EudraVigilance (EV) database. METHODS: All spontaneous EV reports relating to loperamide misuse/abuse/dependence/withdrawal and cardiotoxicity issues were here retrieved, performing a descriptive analysis. FINDINGS: During the years 2005-2017, EV collected a number of 1,983 (out of a total of 7,895; 25.11%) loperamide-related misuse/abuse/dependence/withdrawal adverse drug reaction (ADR) reports, with a progressively increasing trend since 2014. Most cases were classified as drug use disorder (37.4%) or intentional overdose (25.4%). Loperamide was used on its own in 41.9% of cases; remaining, polydrug, cases included antidepressants; benzodiazepines; and other OTCs. Some 1,085 (1,085/7,895 = 13.7%) cardiovascular ADRs were reported, being conduction abnormalities and EKG alterations the most frequently identified. CONCLUSIONS: EV data may support the levels of concern relating to loperamide potential of abuse and associated cardiotoxicity issues. PMID- 30286104 TI - Contextual work design and employee innovative work behavior: When does autonomy matter? AB - In environments experiencing fast technological change in which innovative performance is expected, work design research has found that the degree of autonomy positively predicts behavioral and attitudinal work outcomes. Because extant work design research has tended to examine the direct and mediating effects of autonomy on work outcomes such as job satisfaction, examinations of more situational elements and the degree to which the organizational context strengthens or weakens this relationship has been neglected. This study, therefore, takes a context-contingent perspective to investigate the degree to which psychological climate dimensions such as supervisor support, organizational structure and organizational innovation moderate the effects of autonomy (work scheduling autonomy, work methods autonomy, decision-making autonomy) on employee perceived innovative work behavior (IWB). Using a conjoint experiment based on 9,440 assessments nested within 1,180 employees, it was found that all autonomy dimensions had a significant direct effect on employee perceived IWB. Contrary to the Hypotheses, the multi-level analysis did not reveal any moderating effect of the climate dimensions on the relationship between autonomy and employee IWB. This study provides a context-contingent view for the features of work design and gives a more detailed analysis of autonomy, which has previously been seen primarily as a unidimensional construct. PMID- 30286105 TI - Assessment and agreement of the CT appearance pattern and its severity grading of radiation-induced lung injury after stereotactic body radiotherapy for lung cancer. AB - PURPOSE: Radiographic severity of radiation-induced lung injury (RILI) has not been well-studied. The goal of this study was to assess the CT appearance pattern and severity of RILI without consideration of the clinical presentation. MATERIAL AND METHODS: A total of 49 patients, 41 with primary lung cancer and 8 with metastatic lung cancer, were treated by 4-fraction stereotactic body radiotherapy (SBRT). RILI after SBRT was separately assessed by two observers. The early and late CT appearance patterns and CT-based severity grading were explored. RESULTS: The median follow-up period was 39.0 months. In the early CT findings of observers 1 and 2, there was diffuse consolidation in 15 and 8, diffuse ground glass opacity (GGO) in 0 and 0, patchy consolidation and GGO in 17 and 20, patchy GGO in 3 and 3, and no changes in 10 and 14, respectively (kappa = 0.61). In late CT findings of observer 1 and 2, there were modified conventional pattern in 28 and 24, mass-like pattern in 8 and 11, scar-like pattern in 12 and 12, and no changes in 1 and 2, respectively (kappa = 0.63). In the results of the CT-based grading by observers 1 and 2, there were grade 0 in 1 and 2, grade 1 in 10 and 14, grade 2 in 31 and 29, grade 3 in 7 and 4, and none of grade 4 or more, respectively (kappa = 0.66). According to multivariate analyses (MVA), the significant predicting factors of grade 2 or more CT-based RILI were age (p = 0.01), oxygen dependence (p = 0.03) and interstitial shadow (p = 0.03). CONCLUSIONS: The agreement of the CT appearance and CT-based grading between two observers was good. These indicators may be able to provide us with more objective information and a better understanding of RILI. PMID- 30286106 TI - The clinical relevance of ABO blood type in 100 patients with acute subdural hematoma. AB - OBJECTIVE: The correlation of depleted blood through midline shift in acute subdural hematoma remains the most reliable clinical predictor to date. On the other hand, patient's ABO blood type has a profound impact on coagulation and hemostasis. We conducted this study to evaluate the role of patient's blood type in terms of incidence, clinical course and outcome after acute subdural hematoma bleeding. METHODS: 100 patients with acute subdural hematoma treated between 2010 and 2015 at the author's institution were included. Baseline characteristics and clinical findings including Glasgow coma scale, Glasgow outcome scale, hematoma volume, rebleeding, midline shift, postoperative seizures and the presence of anticoagulation were analyzed for their association with ABO blood type. RESULTS: Patient's with blood type O were found to have a lower midline shift (p<0.01) and significantly less seizures (OR: 0.43; p<0.05) compared to non-O patients. Furthermore, patients with blood type A had the a significantly higher midline shift (p<0.05) and a significantly increased risk for postoperative seizures (OR: 4.01; p<0.001). There was no difference in ABO blood type distribution between acute subdural hematoma patients and the average population. CONCLUSION: The ABO blood type has significant influence on acute subdural hematoma sequelae. Patient's with blood type O benefit in their clinical course after acute subdural hematoma whereas blood type A patients are at highest risk for increased midline shift and postoperative seizures. Further studies elucidating the biological mechanisms of blood type depended hemostaseology and its role in acute subdural hematoma are required for the development of an appropriate intervention. PMID- 30286107 TI - RankProt: A multi criteria-ranking platform to attain protein thermostabilizing mutations and its in vitro applications - Attribute based prediction method on the principles of Analytical Hierarchical Process. AB - Attaining recombinant thermostable proteins is still a challenge for protein engineering. The complexity is the length of time and enormous efforts required to achieve the desired results. Present work proposes a novel and economic strategy of attaining protein thermostability by predicting site-specific mutations at the shortest possible time. The success of the approach can be attributed to Analytical Hierarchical Process and the outcome was a rationalized thermostable mutation(s) prediction tool- RankProt. Briefly the method involved ranking of 17 biophysical protein features as class predictors, derived from 127 pairs of thermostable and mesostable proteins. Among the 17 predictors, ionic interactions and main-chain to main-chain hydrogen bonds were the highest ranked features with eigen value of 0.091. The success of the tool was judged by multi fold in silico validation tests and it achieved the prediction accuracy of 91% with AUC 0.927. Further, in vitro validation was carried out by predicting thermostabilizing mutations for mesostable Bacillus subtilis lipase and performing the predicted mutations by multi-site directed mutagenesis. The rationalized method was successful to render the lipase thermostable with optimum temperature stability and Tm increase by 20 degrees C and 7 degrees C respectively. Conclusively it can be said that it was the minimum number of mutations in comparison to the number of mutations incorporated to render Bacillus subtilis lipase thermostable, by directed evolution techniques. The present work shows that protein stabilizing mutations can be rationally designed by balancing the biophysical pleiotropy of proteins, in accordance to the selection pressure.

AB - Since anti-tumor necrosis factor (TNF)-alpha agents (TNF-alpha inhibitors) induce both clinical response and remission in patients with moderate to severe inflammatory bowel disease (IBD), the use of anti-TNF therapies has fundamentally changed the approach to treatment for patients with IBD. Infliximab (IFX) is a TNF-alpha inhibitor approved for the induction and remission of Crohn's disease (CD). However, even among patients who initially demonstrate a clinical response to IFX therapy, secondary loss of response occurs, although the reason remains unknown. We therefore investigated predictive factors associated with the response to IFX in long-term maintenance treatment in Japanese CD patients. Eight types of single-nucleotide polymorphisms (SNPs) were investigated using the real time PCR method, and patient characteristics were collected from the electronic medical records. The Crohn's Disease Activity Index criteria were used as the response to IFX therapy. The observation period was 1 year after IFX had been administered for more than 1 year. Associations between the IFX response and patient characteristics were evaluated using the multivariate logistic regression model. We studied 121 unrelated adult Japanese with CD treated for more than 1 year with IFX as outpatients at Keio University Hospital from November 1, 2014 to November 30, 2015. Among them, 71 were classified as in remisson. In multivariate analysis, patients with the TNF-alpha 857C>T C/C genotype, shorter disease duration, without double dosing, and combination treatment with an immunomodulator had higher remisson rates than those with the C/T or T/T genotype, longer disease duration, with double dosing, and no combination treatment with an immunomodulator. The response to IFX in Japanese CD patients may therefore be predicted by these 4 characteristics in actual clinical practice. PMID- 30286109 TI - A theoretical insight to understand the molecular mechanism of dual target ligand CTA-018 in the chronic kidney disease pathogenesis. AB - The level of the vitamin D in the bloodstream is regulated by cytochrome P450 enzyme 24-hydroxylase A1 (CYP24A1). Over expression of CYP24A1 enzyme is correlated with vitamin D deficiency and resistance to vitamin D therapy. Chronic kidney disease (CKD) patients are commonly reported with the above said expression variations. This deregulation could be solved by ligands that act as a vitamin D receptor (VDR) agonists and CYP24A1 antagonists. Posner et al., (2010) first time reported two new vitamin D analogues namely CTA-091 and CTA-018 to inhibit CYP24A1. The CTA-018 inhibited CYP24A1 with an IC50 27 +/- 6 nM (10 times more potent than the ketoconazole (253 +/- 20 nM)). CTA-018 induced VDR expression (15-fold lower than 1alpha,25(OH)2D3) and is under phase II clinical trial, whereas CTA-091 was not able to efficiently induce the VDR expression (>2000 nM). To explore the molecular mechanism, binding specificity of these two vitamin D analogues along with native ligand was extensively studied through in silico approaches. Through molecular dynamics simulations studies, we shown that the sulfonic group (O = S = O) in the side chain of CTA-018 plays an important role in the regulation of VDR agonistic activity. The electron lone pairs of the sulfonic group that interacted with His393 lead to be a factor for agonistic mechanism of VDR activity. Compared to azol-based compounds, CTA-018 binds the different sites in the CYP24A1 binding cavity and thus it could be a potent antagonistic for CYP24A1enzyme. PMID- 30286110 TI - Non-invasive evaluation of neurovascular coupling in the murine retina by dynamic retinal vessel analysis. AB - BACKGROUND: Impairment of neurovascular coupling (NVC) was recently reported in the context of subarachnoid hemorrhage and may correlate with disease severity and outcome. However, previous techniques to evaluate NVC required invasive procedures. Retinal vessels may represent an alternative option for non-invasive assessment of NVC. METHODS: A prototype of an adapted retinal vessel analyzer was used to assess retinal vessel diameter in mice. Dynamic vessel analysis (DVA) included an application of monochromatic flicker light impulses in predefined frequencies for evaluating NVC. All retinae were harvested after DVA and electroretinograms were performed. RESULTS: A total of 104 retinal scans were conducted in 21 male mice (90 scans). Quantitative arterial recordings were feasible only in a minority of animals, showing an emphasized reaction to flicker light impulses (8 mice; 14 scans). A characteristic venous response to flicker light, however, could observed in the majority of animals. Repeated measurements resulted in a significant decrease of baseline venous diameter (7 mice; 7 scans, p < 0.05). Ex-vivo electroretinograms, performed after in-vivo DVA, demonstrated a significant reduction of transretinal signaling in animals with repeated DVA (n = 6, p < 0.001). CONCLUSIONS: To the best of our knowledge, this is the first non invasive study assessing murine retinal vessel response to flicker light with characteristic changes in NVC. The imaging system can be used for basic research and enables the investigation of retinal vessel dimension and function in control mice and genetically modified animals. PMID- 30286111 TI - Flexible foraging strategies in Pipistrellus pygmaeus in response to abundant but ephemeral prey. AB - There is growing recognition that with sympathetic management, plantation forests may contain more biodiversity than previously thought. However, the extent to which they may support bat populations is contentious. Many studies have demonstrated active avoidance of coniferous plantations and attributed this to the lack of available roost sites and low invertebrate density. In contrast, other work, carried out in plantation dominated landscapes have shown that certain bat species are able to exploit these areas. However, the extent to which bats use plantations for roosting and foraging, or simply move through the plantation matrix to access more favourable sites is unclear. We radio tracked female Pipistrellus pygmaeus over two summers to establish the extent to which individual bats use Sitka Spruce plantations in southern Scotland for foraging and roosting and assess the implications for felling operations on bats. Maternity roosts identified (n = 17) were in all in buildings and most were large (> 500 individuals). We found no evidence of bats roosting in mature Sitka Spruce crop trees, although several bats used roosts in old or dead beech and oak trees as an alternative to their main maternity roost. Home ranges were much larger (mean 9.6 +/- 3.12 km2) than those reported from other studies (0.6-1.6 km2), and it is likely that roost availability rather than food abundance constrains P. pygmaeus use of Sitka Spruce plantations. At the landscape scale, most individuals selected coniferous habitats over other habitat types, covering large distances to access plantation areas, whilst at a local scale bats used forest tracks to access water, felled stands or patches of broadleaf cover within the plantation. Sitka Spruce plantations support a high abundance of Culicoides impuctatus, the Highland midge which may act as a reliable and plentiful food source for females during lactation, an energetically expensive period. The use of felled stands for foraging by bats has implications for forest management as wind turbines, following small-scale felling operations, are increasingly being installed in plantations; wind turbines have been associated with high bat mortality in some countries. Decisions about siting wind turbines in upland plantations should consider the likelihood of increased bat activity post felling. PMID- 30286112 TI - Caricaturing faces to improve identity recognition in low vision simulations: How effective is current-generation automatic assignment of landmark points? AB - PURPOSE: Previous behavioural studies demonstrate that face caricaturing can provide an effective image enhancement method for improving poor face identity perception in low vision simulations (e.g., age-related macular degeneration, bionic eye). To translate caricaturing usefully to patients, assignment of the multiple face landmark points needed to produce the caricatures needs to be fully automatised. Recent development in computer science allows automatic face landmark detection of 68 points in real time and in multiple viewpoints. However, previous demonstrations of the behavioural effectiveness of caricaturing have used higher-precision caricatures with 147 landmark points per face, assigned by hand. Here, we test the effectiveness of the auto-assigned 68-point caricatures. We also compare this to the hand-assigned 147-point caricatures. METHOD: We assessed human perception of how different in identity pairs of faces appear, when veridical (uncaricatured), caricatured with 68-points, and caricatured with 147-points. Across two experiments, we tested two types of low-vision images: a simulation of blur, as experienced in macular degeneration (testing two blur levels); and a simulation of the phosphenised images seen in prosthetic vision (at three resolutions). RESULTS: The 68-point caricatures produced significant improvements in identity discrimination relative to veridical. They were approximately 50% as effective as the 147-point caricatures. CONCLUSION: Realistic translation to patients (e.g., via real time caricaturing with the enhanced signal sent to smart glasses or visual prosthetic) is approaching feasibility. For maximum effectiveness software needs to be able to assign landmark points tracing out all details of feature and face shape, to produce high-precision caricatures. PMID- 30286113 TI - Perfidious synaptic transmission in the guinea-pig auditory brainstem. AB - The presence of 'giant' synapses in the auditory brainstem is thought to be a specialization designed to encode temporal information to support perception of pitch, frequency, and sound-source localisation. These 'giant' synapses have been found in the ventral cochlear nucleus, the medial nucleus of the trapezoid body and the ventral nucleus of the lateral lemniscus. An interpretation of these synapses as simple relays has, however, been challenged by the observation in the gerbil that the action potential frequently fails in the ventral cochlear nucleus. Given the prominence of these synapses it is important to establish whether this phenomenon is unique to the gerbil or can be observed in other species. Here we examine the responses of units, thought to be the output of neurons in receipt of 'giant' synaptic endings, in the ventral cochlear nucleus and the medial nucleus of the trapezoid body in the guinea pig. We found that failure of the action-potential component, recorded from cells in the ventral cochlear nucleus, occurred in ~60% of spike waveforms when recording spontaneous activity. In the medial nucleus of the trapezoid body, we did not find evidence for action-potential failure. In the ventral cochlear nucleus action-potential failures transform the receptive field between input and output of bushy cells. Additionally, the action-potential failures result in "non-primary-like" temporal adaptation patterns. This is important for computational models of the auditory system, which commonly assume the responses of ventral cochlear nucleus bushy cells are very similar to their "primary like" auditory-nerve-fibre inputs. PMID- 30286114 TI - A comparison of Kato-Katz technique to three other methods for diagnosis of Amphimerus spp. liver fluke infection and the prevalence of infection in Chachi Amerindians of Ecuador. AB - BACKGROUND: Recently, a high prevalence of infection by the liver fluke Amphimerus spp. has been documented in the Chachi Amerindians of Ecuador. For diagnosis, no studies exist that compare the sensitivity of different coproparasitological detection techniques. The present study compares the Kato Katz technique with three other coproparasitological methods for detecting eggs of Amphimerus in stools, as well as determines the prevalence of infection in Chachi residents in a Tropical rain forest area in the northwest coast of Ecuador. METHODOLOGY/RESULTS: A total of 105 samples, utilizing the Kato-Katz technique (KK), the spontaneous sedimentation technique in tube (SSTT), the formalin-ether concentration technique (FEC), and direct smear microscopy (DM), were examined. Combining the four methods (fixed "gold" standard), 38 samples were positive with a prevalence of infection of 36.2%. The sensitivities of individual methods were 71%, 58%, 50% and 3% for KK, SSTT, FEC, and DM respectively. Our results indicated that KK alone had the best performance, detecting 27 (71%) of the 38 positive samples. The combination of KK and SSTT detected amphimeriasis in 36 (95%) samples, and KK and FEC in 31 (82%) samples. CONCLUSIONS: DM showed the lowest sensitivity, which raises concern for its value, because it is the standard technique for stool examination for detection of parasites in both public and private laboratories in Ecuador. SSTT alone detected eggs in 22 samples (58%) and would be recommended for field studies because of its simplicity. Performing two techniques on a single sample enhances the detection of Amphimerus infection. Its sensitivity is relative to a fixed "gold" standard, determined as the combined results of the four techniques performed. This study confirms the high prevalence of human infection by Amphimerus in the indigenous Chachi group where the first human cases were described. PMID- 30286116 TI - Waterbird response to variable-timing of drawdown in rice fields after winter flooding. AB - Wetland loss and degradation have been extensive across the world, especially in California's Central Valley where over 90% of the natural wetlands have been converted to agricultural and urban uses. In the Central Valley today, a much smaller network of managed wetlands and flooded agricultural fields supports almost five million waterfowl and half a million shorebirds. Over 50% of waterbird habitat in the Central Valley is provided by flooded agricultural land, primarily rice (Oryza sativa). Each year non-breeding waterbird habitat decreases in the late winter as flooded agricultural fields are drained after waterfowl hunting season in late-January to prepare for the next crop. This study evaluated a practice called 'variable drawdown' that involves delaying the removal of water from rice fields by 1, 2, and 3 weeks to extend the availability of flooded habitat later into February and March. We studied waterbird response to variable drawdown in 2012 and 2013 at twenty rice farms throughout the northern half of the Central Valley. The staggered drawdown created a mosaic of water depths throughout the six-week study period. The 3-week delay in drawdown supported more dabbling ducks than earlier drawdowns in the first half of the study and more shorebirds and long-legged wading birds during the second half of the study. The timing of highest use of each drawdown treatment differed for each waterbird guild; dabbling ducks, geese and swans benefited at the beginning, then long legged wading birds, followed by shorebirds. Despite the presence of appropriate water depths for shorebirds across the treatments during the entire study period, shorebird densities were highest near the end of the study when the 3-week delayed drawdown was providing the majority of the habitat on the landscape. This suggests that shorebirds may have concentrated in our study fields due to decreasing availability of shallow water habitat elsewhere. The practice of variable drawdown successfully extended the availability of waterbird habitat provided by post-harvest flooded rice fields later into winter. PMID- 30286115 TI - An improved method for extraction of polar and charged metabolites from cyanobacteria. AB - A key requirement for 13C Metabolic flux analysis (13C-MFA), a widely used technique to estimate intracellular metabolic fluxes, is an efficient method for the extraction of intermediate metabolites for analysis via liquid chromatography mass spectrometry (LC/MS). The 13C isotopic labeling results in further distribution of an already sparse pool of intermediate metabolites into isotopologues, each appearing as a separate chromatographic feature. We examined some of the reported solvent systems for the extraction of polar intracellular metabolites from three strains of cyanobacteria of the genus Synechococcus, viz., Synechococcus sp. PCC 7002, Synechococcus elongatus PCC 7942, and a newly isolated Synechococcus elongatus PCC 11801 (manuscript under review). High resolution-LC/MS was used to assess the relative abundance of the extracted metabolites. The different solvent systems used for extraction led to statistically significant changes in the extraction efficiency for a large number of metabolites. While a few hundred m/z features or potential metabolites were detected with different solvent systems, the abundance of over a quarter of all metabolites varied significantly from one solvent system to another. Further, the extraction methods were evaluated for a targeted set of metabolites that are important in 13C-MFA studies of photosynthetic organisms. While for the strain PCC 7002, the reported method using methanol-chloroform-water system gave satisfactory results, a mild base in the form of NH4OH had to be used in place of water to achieve adequate levels of extraction for PCC 7942 and PCC 11801. While minor changes in extraction solvent resulted in dramatic changes in the extraction efficiency of a number of compounds, certain metabolites such as amino acids and organic acids were adequately extracted in all the solvent systems tested. Overall, we present a new improved method for extraction using a methanol chloroform-NH4OH system. Our method improves the extraction of polar compounds such as sugar phosphates, bisphosphates, that are central to 13C-MFA studies. PMID- 30286117 TI - Antimicrobial activity of NO-releasing compounds against periodontal pathogens. AB - This study describes the successful synthesis of nitric oxide (NO)-releasing compounds with biodegradable and injectable properties and demonstrates that the kinetics of NO release vary according to the type of NO donor. The antimicrobial activity of NO-releasing compounds against three common periodontal pathogens, i.e., Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Actinomyces israelii, was investigated using a susceptibility assay. Human gingival fibroblasts were treated with NO-releasing compounds at the minimum concentrations required for bacterial growth and cytotoxicity was evaluated using the MTT cell proliferation assay. Our results suggest that NO-releasing compounds can be used topically to treat both gram-negative and gram-positive periodontal pathogens. Comparison of the antimicrobial activity and cytotoxicity assay results between the NO-releasing compounds revealed that an NO donor comprising a macromolecule without surface charge, a lower instantaneous NO concentration, and an adequate supply of NO were associated with a strong bactericidal effect and low cytotoxicity. NO-releasing compounds with these properties may be suitable for treatment of periodontitis. PMID- 30286118 TI - The medical assistance system and inpatient health care provision: Empirical evidence from short-term hospitalizations in Japan. AB - This paper uses two nationally representative sets of medical claims data from medical assistance and universal public health insurance systems to examine how medical assistance system assignment affects short-term inpatient health care provision. In Japan, the medical assistance system, which is part of a public assistance system, provides medical care services for its beneficiaries without imposing any financial burdens, such as copayments or advance premium payments. These circumstances can lead to inpatient costs, as physicians may provide more treatments because there is a financial incentive. Because the assignment of public assistance in Japan is not random but is subject to means testing by the local government, I employ the instrumental variable model to control the potential correlation. I find that medical expenditure is significantly higher for medical assistance patients than for universal public health insurance patients, with an arc elasticity of approximately 0.20. This elasticity is slightly greater than that found for inpatient care in the randomized RAND Health Insurance Experiment and recent empirical studies on low-income populations. In addition, the elasticities for patients who receive medication, treatment and surgery are greater. PMID- 30286119 TI - Agreement between CDC/NHSN surveillance definitions and ECDC criteria in diagnosis of healthcare-associated infections in Serbian trauma patients. AB - After three national point prevalence studies (PPS) of healthcare associated infections (HAI) conducted in Serbian acute care hospitals using US (CDC/NHSN) surveillance definitions, Serbia is about to switch to European (ECDC) criteria for the purpose of the fourth HAI PPS. The aim of this study was to compare the US and the European HAI definitions in Serbian trauma intensive care unit (ICU). Prospective surveillance was performed at two surgical-trauma ICUs of the Emergency department of Clinical Center of Serbia. HAIs were prospectively diagnosed by experienced clinician and epidemiologists using both types of HAI definitions simultaneously. The level of agreement between two case definitions was assessed by Cohen's kappa statistic (k). Of 406 patients, 107 (26.3%) acquired at least one HAI (total of 107 according to US definitions and 141 according to European criteria). For microbiologically confirmed pneumonia agreement was k = 0.99 (95% CI, 0.96-1.00) and for clinically defined k = 0.86 (95% CI, 0.58-1.00). Agreement for bloodstream infections (BSI) was 0.79 (CI 95%, 0.70-0.89). When secondary BSI was excluded from the European classification, (30.9% of all BSI), concordance was k = 1.00 and when microbiologically confirmed catheter related BSI were reported separately as recommended by latest ECDC protocol update, (20.0% of all BSI), concordance was 0.60 (CI 95%, 0.41-0.80). No agreement was found between CLABSI and CRI while slight agreement was found when compared CLABSI and CRI3 (k = 0.11; 95%CI, 0.0-0.22). Agreement for overall UTI was moderate (k = 0.66; 95%CI, 0.53-0.79) while for microbiologically-confirmed symptomatic UTI was perfect (k = 1.00). For CAUTI good agreement was observed (k = 0.77; 95%CI, 0.34-1.0). Microbiological confirmation of PN and UTI should be stimulated and comparison of BSI should be done with emphasis on whether secondary BSI is included. PMID- 30286120 TI - The beneficial application of preoperative 3D printing for surgical stabilization of rib fractures. AB - OBJECTIVES: The beneficial application of three-dimensional (3D) printing for surgical stabilization of rib fractures (SSRF) has never been proposed in the literature before. The aim of this study was to verify patients' surgical outcomes when utilizing preoperative three-dimensional printing for SSRF. METHODS: We retrospectively reviewed the records of all consecutive patients who were treated at our hospital for SSRF from July 2015 to December 2017. The patients were divided into two groups according to whether or not 3D printing was utilized. RESULTS: Forty-eight patients who underwent SSRF at our hospital were enrolled. Of them, three patients underwent bilateral surgeries. The patients with application of preoperative 3D printing for SSRF had statistically significant associations with shorter operation time per fixed plate (p < 0.001), and a smaller incision length (p < 0.001). CONCLUSIONS: We present an useful technique involving 3D printing for promoting SSRF significantly with shorter operation time and an appropriate incision length. PMID- 30286121 TI - Large-scale mitochondrial DNA analysis reveals new light on the phylogeography of Central and Eastern-European Brown hare (Lepus europaeus Pallas, 1778). AB - European brown hare, Lepus europaeus, from Central and Eastern European countries (Hungary, Poland, Serbia, Lithuania, Romania, Georgia and Italy) were sampled, and phylogenetic analyses were carried out on two datasets: 1.) 137 sequences (358 bp) of control region mtDNA; and 2.) 105 sequences of a concatenated fragment (916 bp), including the cytochrome b, tRNA-Thr, tRNA-Pro and control region mitochondrial DNA. Our sequences were aligned with additional brown hare sequences from GenBank. A total of 52 and 51 haplotypes were detected within the two datasets, respectively, and assigned to two previously described major lineages: Anatolian/Middle Eastern (AME) and European (EUR). Furthermore, the European lineage was divided into two subclades including South Eastern European (SEE) and Central European (CE). Sympatric distribution of the lineages of the brown hare in South-Eastern and Eastern Europe revealed contact zones there. BAPS analysis assigned sequences from L. europaeus to five genetic clusters, whereas CE individuals were assigned to only one cluster, and AME and SEE sequences were each assigned to two clusters. Our findings uncover numerous novel haplotypes of Anatolian/Middle Eastern brown hare outside their main range, as evidence for the combined influence of Late Pleistocene climatic fluctuations and anthropogenic activities in shaping the phylogeographic structure of the species. Our results support the hypothesis of a postglacial brown hare expansion from Anatolia and the Balkan Peninsula to Central and Eastern Europe, and suggest some slight introgression of individual haplotypes from L. timidus to L. europaeus. PMID- 30286122 TI - Is obstructive sleep apnea associated with difficult airway? Evidence from a systematic review and meta-analysis of prospective and retrospective cohort studies. AB - BACKGROUND: Difficult airway management and obstructive sleep apnea may contribute to increased risk of perioperative morbidity and mortality. The objective of this systematic review and meta-analysis (SRMA) is to evaluate the evidence of a difficult airway being associated with obstructive sleep apnea (OSA) patients undergoing surgery. METHODS: The standard databases were searched from 1946 to April 2017 to identify the eligible articles. The studies which included adult surgical patients with either suspected or diagnosed obstructive sleep apnea must report at least one difficult airway event [either difficult intubation (DI), difficult mask ventilation (DMV), failed supraglottic airway insertion or difficult surgical airway] in sleep apnea and non-sleep apnea patients were included. RESULTS: Overall, DI was 3.46-fold higher in the sleep apnea vs non-sleep apnea patients (OSA vs. non-OSA: 13.5% vs 2.5%; OR 3.46; 95% CI: 2.32-5.16, p <0.00001). DMV was 3.39-fold higher in the sleep apnea vs non sleep apnea patients (OSA vs. non-OSA: 4.4% vs 1.1%; OR 3.39; 95% CI: 2.74-4.18, p <0.00001). Combined DI and DMV was 4.12-fold higher in the OSA vs. non-OSA patients (OSA vs. non-OSA: 1.1% vs 0.3%; OR 4.12; 95% CI: 2.93-5.79, p <0.00001). There was no significant difference in the supraglottic airway failure rates in the sleep apnea vs non-sleep apnea patients (OR: 1.34; 95% CI: 0.70-2.59; p = 0.38). Meta-regression to adjust for various subgroups and baseline confounding factors did not impact the final inference of our results. CONCLUSION: This SRMA found that patients with obstructive sleep apnea had a three to four-fold higher risk of difficult intubation or mask ventilation or both, when compared to non sleep apnea patients. PMID- 30286123 TI - An improved memory-based collaborative filtering method based on the TOPSIS technique. AB - This paper describes an approach for improving the accuracy of memory-based collaborative filtering, based on the technique for order of preference by similarity to ideal solution (TOPSIS) method. Recommender systems are used to filter the huge amount of data available online based on user-defined preferences. Collaborative filtering (CF) is a commonly used recommendation approach that generates recommendations based on correlations among user preferences. Although several enhancements have increased the accuracy of memory based CF through the development of improved similarity measures for finding successful neighbors, there has been less investigation into prediction score methods, in which rating/preference scores are assigned to items that have not yet been selected by a user. A TOPSIS solution for evaluating multiple alternatives based on more than one criterion is proposed as an alternative to prediction score methods for evaluating and ranking items based on the results from similar users. The recommendation accuracy of the proposed TOPSIS technique is evaluated by applying it to various common CF baseline methods, which are then used to analyze the MovieLens 100K and 1M benchmark datasets. The results show that CF based on the TOPSIS method is more accurate than baseline CF methods across a number of common evaluation metrics. PMID- 30286124 TI - The effect of naltrexone as a carboplatin chemotherapy-associated drug on the immune response, quality of life and survival of dogs with mammary carcinoma. AB - The objective of this study was to evaluate the effect of low-dose naltrexone (LDN) as a carboplatin chemotherapy-associated drug in female dogs with mammary carcinoma in benign mixed tumors (MC-BMT) after mastectomy and to assess its association with quality of life and survival rates. Sixty female dogs were included in this study, all of which had histopathological diagnosis of MC-BMT and were divided into three groups: G1 (control), consisting of animals submitted only to mastectomy with or without regional metastasis; G2, composed of treated animals that did not present with metastasis; and G3, treated dogs that presented with metastasis. G2 and G3 were also subdivided according to the treatment administered: chemotherapy alone (MC-BMT(-) C/MC-BMT(+) C) or LDN and chemotherapy (MC-BMT(-) C+LDN/MC-BMT(+) C+LDN). All animals were subjected to clinical evaluation, mastectomy, peripheral blood lymphocyte immunophenotyping, beta-endorphin and met-enkephalin quantification, and evaluation of survival rates and quality of life scores. The results showed higher serum concentrations of beta-endorphin and met-enkephalin, fewer chemotherapy-related side effects, and better quality of life and survival rates in the LDN-treated groups than in LDN-untreated groups (P < 0.05). Evaluation of clinical and pathological parameters indicated a significant association between the use of LDN and both prolonged survival and enhanced quality of life. These results indicate that LDN is a viable chemotherapy-associated treatment in female dogs with MC-BMT, maintaining their quality of life and prolonging survival rates. PMID- 30286125 TI - Examining the impact of distance as a contextual cue in evaluative conditioning. AB - According to a symbolic perspective on EC, pairings constitute a relational contextual cue in the environment. It is the relationship between stimuli as cued by the pairing (i.e., pairings = similar) that determines the observed change in liking. Across five pre-registered studies (N = 747) we manipulated the absolute or relative distance between different pairs of conditioned (CS) and unconditioned stimuli (US) under the assumption that this would influence the type of relation that the pairings would cue (i.e., close = similar; far = different). In all five studies we obtained repeated and strong evidence that stimulus pairings led to changes in implicit and explicit evaluations. Although we found that these effects were moderated by absolute distance manipulations, evidence did not emerge indicating that those same effects were moderated by relative distance manipulations. These findings fail to provide strong support for a symbolic perspective on EC. We discuss the implications of our findings as well as future research in this area. PMID- 30286126 TI - Cytoplasmic, nuclear, and total PBK/TOPK expression is associated with prognosis in colorectal cancer patients: A retrospective analysis based on immunohistochemistry stain of tissue microarrays. AB - OBJECTIVE: PDZ-binding kinase/T-LAK cell-originated protein kinase (PBK/TOPK) regulates components of the cell cycle, including cell growth, immune responses, DNA damage repair, apoptosis, and inflammation. PBK/TOPK may also accelerate tumorigenesis in colorectal cancer. METHODS: We investigated the impact of PBK/TOPK on the clinical outcome of colorectal cancer patients to further identify its role in colorectal cancer. PBK/TOPK immunoreactivity was analyzed by immunohistochemistry in 162 cancer specimens from primary colorectal cancer patients. RESULTS: The mean follow-up time after surgery was 5.4 years (medium: 3.9 years; range 0.01 to 13.1 years). The prognostic value of PBK/TOPK on overall survival was determined by Kaplan-Meier analysis and Cox proportional hazard models. PBK/TOPK was expressed in both the cytoplasm and nucleus. High PBK/TOPK expression in tumor cells was significantly associated with advanced T value. The 5-year survival rate was greater for patients with high total PBK/TOPK expression than with low PBK/TOPK expression (58.3% vs 34.4%, P = 0.005). Multivariate analyses showed that low-scoring cytoplasmic PBK/TOPK, negative nuclear PBK/TOPK, low total PBK/TOPK, and advanced tumor stage were correlated with poor overall patient survival. CONCLUSIONS: We suggest that PBK/TOPK expression, detected by IHC staining, could be used as an independent prognostic marker for colorectal cancer patients. PMID- 30286127 TI - Implementation of the hybrid course on basic wheelchair service provision for Colombian wheelchair service providers. AB - INTRODUCTION: People with mobility impairments often rely on wheelchairs as their primary means of mobility. Untrained wheelchair service providers may provide inappropriate wheelchairs and services which result in negative consequences in wheelchair users' health, quality of life, safety, and social participation. This study aimed to evaluate the influence of the Spanish Hybrid Course on Basic Wheelchair Service Provision, a training based on the World Health Organization's Wheelchair Service Training Program-Basic Level, to increase knowledge in basic level wheelchair service provision among a group of wheelchair service providers from Colombia. In addition, we developed a satisfaction survey which participants completed after the training to understand levels of satisfaction with the training intervention. METHODS: A quasi-experimental study was conducted to evaluate changes in basic level wheelchair knowledge using the Wheelchair Service Provision-Basic Test. Paired sample t tests were used to assess pre-and post training changes in basic level wheelchair knowledge. The Hybrid Satisfaction Survey was developed in collaboration with a multidisciplinary, international stakeholders' group. The survey's construct of interest was level of satisfaction determined by interaction, instructor, instruction methodology, content, and technology, using a five-point Likert scale (0 = strongly disagree to 4 = strongly agree). The survey was completed anonymously after the training intervention and analyzed using frequencies and percentages. RESULTS: Fifteen wheelchair service providers in Colombia completed the Spanish Hybrid Course. Mean post-scores were significantly higher (Mean (M) = 56.13, Standard Deviation (SD) = 7.8), than pre-assessment scores (M = 50.07, SD = 8.38, t(14) = 4.923, p = <0.0001). Participants who completed the surveys (N = 15) reported that the Spanish Hybrid Course was well received, with 98.66% of responses distributed in favorable levels (>3). CONCLUSIONS: The Spanish Hybrid Course proved to be effective in increasing basic level wheelchair knowledge with a high satisfaction level among participants. Further testing is needed to evaluate the effectiveness of this course across different individuals and countries as a potential tool to build professional capacity in basic level wheelchair provision. PMID- 30286128 TI - Determining fuel moisture thresholds to assess wildfire hazard: A contribution to an operational early warning system. AB - Fuel moisture content (FMC) is an important fuel property for assessing wildfire hazard, since it influences fuel flammability and fire behavior. The relationship between FMC and fire activity differs among land covers and seems to be a property of each ecosystem. Our objectives were to analyze pre-fire FMC among different land covers and to propose a wildfire hazard classification for the Sierras Chicas in the Chaco Serrano subregion (Argentina), by analyzing pre-fire FMC distributions observed for grasslands, shrublands and forests and using percentiles to establish thresholds. For this purpose, we used a fire database derived from Landsat imagery (30 m) and derived FMC maps every 8 days from 2002 to 2016 using MODIS reflectance products and empirical equations of FMC. Our results indicated that higher FMC constrains the extent of wildfires, whereas at lower FMC there are other factors affecting their size. Extreme and high fire hazard thresholds for grasslands were established at FMC of 55% and 67% respectively, at 72% and 105% for forests and at 106% and 121% for shrublands. Our FMC thresholds were sensitive to detect extreme fire hazard conditions during years with high fire activity in comparison to average conditions. The differences in the distributions of pre-fire FMC among land covers and between ecosystems highlighted the need to locally determine land cover-specific FMC thresholds to assess wildfire hazard. Our wildfire hazard classification applied to FMC maps in an operational framework will contribute to improving early warning systems in the Sierras Chicas. However, moisture alone is not sufficient to represent true fire hazard in Chaco forests and the combination with other variables would provide better hazard assessments. These operational wildfire hazard maps will help to better allocation of fire protective resources to minimize negative impact on people, property and ecosystems. To the best of our knowledge, this is the first study analyzing pre-fire FMC over several fire seasons in a non-Mediterranean ecosystem, aiming at assessing wildfire hazard. PMID- 30286129 TI - Retention of knowledge and skills after Emergency Obstetric Care training: A multi-country longitudinal study. AB - OBJECTIVE: To determine retention of knowledge and skills after standardised "skills and drills" training in Emergency Obstetric Care. DESIGN: Longitudinal cohort study. SETTING: Ghana, Malawi, Nigeria, Kenya, Tanzania and Sierra Leone. POPULATION: 609 maternity care providers, of whom 455 were nurse/midwives (NMWs). METHODS: Knowledge and skills assessed before and after training, and, at 3, 6, 9 and 12 months. Analysis of variance to explore differences in scores by country and level of healthcare facility for each cadre. Mixed effects regression analysis to account for potential explanatory factors including; facility type, years of experience providing maternity care, months since training and number of repeat assessments. MAIN OUTCOME MEASURES: Change in knowledge and skills. RESULTS: Before training the overall mean (SD) score for skills was 48.8% (11.6%) and 65.6% (10.7%). for knowledge. After training the mean (95% CI) relative improvement in knowledge was 30.8% (29.1% - 32.6%) and 59.8% (58.6%- 60.9%) for skills. Mean scores for knowledge and skills at each subsequent assessment remained between those immediately post-training and those at 3 months. NMWs who attended all four assessments demonstrated statistically better retention of skills (14.9%, 95% CI 7.8%, 22.0% p<0.001) but not knowledge (8.6%, 95% CI -0.3%, 17.4%. p = 0.06) compared to those who attended one or two assessments only. Health care facility level or experience were not determinants of retention. CONCLUSIONS: After training, healthcare providers retain knowledge and skills for up to 12 months. This effect can likely be enhanced by short repeat skills training sessions, or, 'fire drills'. PMID- 30286130 TI - An easy and safe training method for trunk function improves mobility in total knee arthroplasty patients: A quasi-randomized controlled trial. AB - OBJECTIVE: Total knee arthroplasty (TKA) is aimed mainly at reducing pain and restoring mobility. However, mobility deficits can persist even longer than 1 year. The trunk function and movement velocity of any region have been recently recognized to be critical for determining mobility in older people. Therefore, the main goal of this quasi-randomized trial is to clarify the effectiveness of a novel training method, the seated side tapping (SST) training, for improving mobility by focusing on movement velocity of trunk function in the short term after TKA. METHODS: SST training consists of side trunk movements repeated as quickly as possible in a seated position. All participants after TKA were randomly assigned to the SST training group (n = 37) or control training group (n = 38). The participants in the SST group performed SST training plus the standard rehabilitation program 5 days per week for 3 weeks after TKA, while the control group performed only the standard rehabilitation programs. The primary outcome was the effect of SST training on mobility, indicated by gait speed and the timed up and go test (TUG) time. Measurements were performed before and 1, 2, and 3 weeks after surgery. RESULTS: At all-time points, the patients in the SST group showed significantly better mobility, despite that knee function, represented by muscle strength, range of motion, and degree of pain at the knee joint, was similar in both groups. The difference in gait speed between the groups was >0.1 m/s at all time points, which is clinically significant. CONCLUSION: SST training significantly improved patients' mobility within 3 weeks after TKA, despite that no additional benefit was observed in knee function. The findings in this study indicate that SST training may be considered as a part of the rehabilitation program after TKA, although further evaluation of its long-term effectiveness is needed. TRIAL REGISTRATION: University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR; UMIN000027909). PMID- 30286131 TI - Health-related quality of life in patients with autoimmune hepatitis: A questionnaire survey. AB - AIM: Health-related quality of life is impaired in patients with autoimmune hepatitis, but the association between health-related quality of life and patients' backgrounds remains unknown. We assessed health-related quality of life in patients with autoimmune hepatitis and identified factors associated with its impairment. METHODS: We assessed health-related quality of life in patients with autoimmune hepatitis, patients with chronic hepatitis C, and healthy subjects using the Japanese version of the Chronic Liver Disease Questionnaire and the 36 Item Short Form Survey. We compared health-related quality of life in patients with autoimmune hepatitis with that of patients with chronic hepatitis C and healthy subjects. RESULTS: A total of 265 patients with autoimmune hepatitis, 88 patients with chronic hepatitis C, and 97 healthy subjects were enrolled; most patients were women. The median ages of patients were 65, 66, and 57 years, respectively. Of these patients with autoimmune hepatitis, 10.6% and 57.0% had cirrhosis and comorbid diseases, respectively. The overall Chronic Liver Disease Questionnaire scores (5.5 vs. 6.2, P < 0.001) and physical (48.1 vs. 54.2, P < 0.001) and mental (51.8 vs. 55.0, P = 0.004) component summaries of 36-Item Short Form Survey were significantly lower in patients with autoimmune hepatitis than in healthy subjects, and similar to scores in patients with chronic hepatitis C. Having cirrhosis, comorbid diseases, and treatment for autoimmune hepatitis were associated with impaired health-related quality of life among patients with autoimmune hepatitis. In particular, prednisolone use was associated with lower scores on the worry domain of the Chronic Liver Disease Questionnaire. CONCLUSIONS: Patients with autoimmune hepatitis showed impairment in health related quality of life, which was associated with not only disease progression, but also comorbid diseases and treatment. Ways to improve health-related quality of life should be considered in patients with AIH when disease outcome is not favorable and when using prednisolone. PMID- 30286132 TI - CRISPR deletion of MIEN1 in breast cancer cells. AB - Migration and Invasion Enhancer (MIEN1) is an oncogene which is involved in facilitating motility of cancer cells through actin dynamics and gene expression. Increased MIEN1 expression in many types of tumors leads to disease progression and metastatic propensity. It is unclear precisely how MIEN1 is involved in this process and more studies are required to tease out the mechanisms. Here we show that Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR) genome editing effectively produced specific genomic deletions in the MIEN1 gene which led to the abrogation of its expression in breast cancer cells. The single guide RNAs (sgRNAs) mediated targeting of MIEN1 was specific and none of the clones screened for off-target cleavage revealed any insertions or deletions (indels). Additionally, disruption of the MIEN1 gene did not alter the cell morphology, growth, proliferation or survival. Knocking out MIEN1 in these breast cancer cells will allow future studies to determine the exact role MIEN1 plays in breast tumor metastasis, which might lead to production of novel therapeutics to treat this and other cancers. PMID- 30286134 TI - Understanding intersections of social determinants of maternal healthcare utilization in Uttar Pradesh, India. AB - OBJECTIVE: To explore intersections of social determinants of maternal healthcare utilization using the Classification and Regression Trees (CART) algorithm which is a machine-learning method used to construct prediction models. METHODS: Institutional review board approval for this study was granted from Public Health Service-Ethical Review Board (PHS-ERB) and from the Health Ministry Screening Committee (HMSC) facilitated by Indian Council for Medical Research (ICMR). IRB review and approval for the current analyses was obtained from University of California, San Diego. Cross-sectional data were collected from women with children aged 0-11 months (n = 5,565) from rural households in 25 districts of Uttar Pradesh, India. Participants were surveyed on maternal healthcare utilization including registration of pregnancy (model-1), receipt of antenatal care (ANC) during pregnancy (model-2), and delivery at health facilities (model 3). Social determinants of health including wealth, social group, literacy, religion, and early age at marriage were captured during the survey. The Classification and Regression Tree (CART) algorithm was used to explore intersections of social determinants of healthcare utilization. RESULTS: CART analyses highlight the intersections, particularly of wealth and literacy, in maternal healthcare utilization in Uttar Pradesh. Model-1 documents that women who are poorer, illiterate and Muslim are less likely to have their pregnancies registered (71.4% vs. 86.0% in the overall sample). Model-2 documents that poorer, illiterate women had the lowest ANC coverage (37.7% vs 45% in the overall sample). Model-3, developed for deliveries at health facilities, highlighted that illiterate and poor women have the lowest representation among facility deliveries (59.6% vs. 69% in the overall sample). CONCLUSION: This paper explores the interactions between determinants of maternal healthcare utilization indicators. The findings in this paper highlights that the interaction of wealth and literacy can play a very strong role in accentuating or diminishing healthcare utilization among women. The study also reveals that religion and women's age at marriage also interact with wealth and literacy to create substantial disparities in utilization. The study provides insights into the effect of intersections of determinants, and highlights the importance of using a more nuanced understanding of the impact of co-occurring forms of marginalization to effectively tackle inequities in healthcare utilization. PMID- 30286135 TI - High tension in sarcomeres hinders myocardial relaxation: A computational study. AB - Experiments have shown that the relaxation phase of cardiac sarcomeres during an isometric twitch is prolonged in muscles that reached a higher peak tension. However, the mechanism is not completely understood. We hypothesize that the binding of calcium to troponin is enhanced by the tension in the thin filament, thus contributing to the prolongation of contraction upon higher peak tension generation. To test this hypothesis, we developed a computational model of sarcomere mechanics that incorporates tension-dependence of calcium binding. The model was used to simulate isometric twitch experiments with time dependency in the form of a two-state cross-bridge cycle model and a transient intracellular calcium concentration. In the simulations, peak isometric twitch tension appeared to increase linearly by 51.1 KPa with sarcomere length from 1.9 MUm to 2.2 MUm. Experiments showed an increase of 47.3 KPa over the same range of sarcomere lengths. The duration of the twitch also increased with both sarcomere length and peak intracellular calcium concentration, likely to be induced by the inherently coupled increase of the peak tension in the thin filament. In the model simulations, the time to 50% relaxation (tR50) increased over the range of sarcomere lengths from 1.9 MUm to 2.2 MUm by 0.11s, comparable to the increased duration of 0.12s shown in experiments. Model simulated tR50 increased by 0.12s over the range of peak intracellular calcium concentrations from 0.87 MUM to 1.45 MUM. Our simulation results suggest that the prolongation of contraction at higher tension is a result of the tighter binding of Ca2+ to troponin in areas under higher tension, thus delaying the deactivation of the troponin. PMID- 30286136 TI - Uncovering the relation between clinical reasoning and diagnostic accuracy - An analysis of learner's clinical reasoning processes in virtual patients. AB - BACKGROUND: Clinical reasoning is an important topic in healthcare training, assessment, and research. Virtual patients (VPs) are a safe environment to teach, assess and perform research on clinical reasoning and diagnostic accuracy. Our aim was to explore the details of the clinical reasoning process and diagnostic accuracy of undergraduate medical students when working with VPs using a concept mapping tool. METHODS: Over seven months we provided access to 67 German and 30 English VPs combined with a concept mapping tool to visualize and measure the clinical reasoning process of identifying problems, differential diagnoses, recommended tests and treatment options, and composing a summary statement about a VP. A final diagnosis had to be submitted by the learners in order to conclude the VP scenario. Learners were allowed multiple attempts or could request the correct diagnosis from the system. RESULTS: We analyzed 1,393 completed concept maps from 317 learners. We found significant differences between maps with a correct final diagnosis on one or multiple attempts and maps in which learners gave up and requested the solution from the system. These maps had lower scores, fewer summary statements, and fewer problems, differential diagnoses, tests, and treatments. CONCLUSIONS: The different use patterns and scores between learners who had the correct final diagnosis on one or multiple attempts and those who gave up, indicate that diagnostic accuracy in the form of a correct final diagnosis on the first attempt has to be reconsidered as a sole indicator for clinical reasoning competency. For the training, assessment, and research of clinical reasoning we suggest focusing more on the details of the process to reach a correct diagnosis, rather than whether it was made in the first attempt. PMID- 30286137 TI - Novel gateway binary vectors for rapid tripartite DNA assembly and promoter analysis with various reporters and tags in the liverwort Marchantia polymorpha. AB - The liverwort Marchantia polymorpha is an emerging model species for basal lineage plant research. In this study, two Gateway cloning-compatible binary vector series, R4pMpGWB and R4L1pMpGWB, were generated to facilitate production of transgenic M. polymorpha. The R4pMpGWB series allows tripartite recombination of any promoter and any coding sequence with a specific reporter or tag. Reporters/tags for the R4pMpGWB series are GUS, ELuc(PEST), FLAG, 3*HA, 4*Myc, mRFP1, Citrine, mCitrine, ER-targeted mCitrine and nucleus-targeted mCitrine. The R4L1pMpGWB series is suitable for promoter analysis. R4L1pMpGWB vector structure is the same as that of R4pMpGWB vectors, except that the attR2 site is replaced with attL1, enabling bipartite recombination of any promoter with a reporter or tag. Reporters/tags for the R4L1pMpGWB series are GUS, G3GFP-GUS, LUC, ELuc(PEST), Citrine, mCitrine, ER-targeted mCitrine and mCitrine-NLS. Both vector series were functional in M. polymorpha cells. These vectors will facilitate the design and assembly of plasmid constructs and generation of transgenic M. polymorpha. PMID- 30286133 TI - Role of extracellular matrix and microenvironment in regulation of tumor growth and LAR-mediated invasion in glioblastoma. AB - The cellular dispersion and therapeutic control of glioblastoma, the most aggressive type of primary brain cancer, depends critically on the migration patterns after surgery and intracellular responses of the individual cancer cells in response to external biochemical cues in the microenvironment. Recent studies have shown that miR-451 regulates downstream molecules including AMPK/CAB39/MARK and mTOR to determine the balance between rapid proliferation and invasion in response to metabolic stress in the harsh tumor microenvironment. Surgical removal of the main tumor is inevitably followed by recurrence of the tumor due to inaccessibility of dispersed tumor cells in normal brain tissue. In order to address this complex process of cell proliferation and invasion and its response to conventional treatment, we propose a mathematical model that analyzes the intracellular dynamics of the miR-451-AMPK- mTOR-cell cycle signaling pathway within a cell. The model identifies a key mechanism underlying the molecular switches between proliferative phase and migratory phase in response to metabolic stress in response to fluctuating glucose levels. We show how up- or down regulation of components in these pathways affects the key cellular decision to infiltrate or proliferate in a complex microenvironment in the absence and presence of time delays and stochastic noise. Glycosylated chondroitin sulfate proteoglycans (CSPGs), a major component of the extracellular matrix (ECM) in the brain, contribute to the physical structure of the local brain microenvironment but also induce or inhibit glioma invasion by regulating the dynamics of the CSPG receptor LAR as well as the spatiotemporal activation status of resident astrocytes and tumor-associated microglia. Using a multi-scale mathematical model, we investigate a CSPG-induced switch between invasive and non-invasive tumors through the coordination of ECM-cell adhesion and dynamic changes in stromal cells. We show that the CSPG-rich microenvironment is associated with non invasive tumor lesions through LAR-CSGAG binding while the absence of glycosylated CSPGs induce the critical glioma invasion. We illustrate how high molecular weight CSPGs can regulate the exodus of local reactive astrocytes from the main tumor lesion, leading to encapsulation of non-invasive tumor and inhibition of tumor invasion. These different CSPG conditions also change the spatial profiles of ramified and activated microglia. The complex distribution of CSPGs in the tumor microenvironment can determine the nonlinear invasion behaviors of glioma cells, which suggests the need for careful therapeutic strategies. PMID- 30286138 TI - Effects of metformin use on total mortality in patients with type 2 diabetes and chronic obstructive pulmonary disease: A matched-subject design. AB - BACKGROUNDS: Few studies have investigated the therapeutic effects of metformin in patients with type 2 diabetes mellitus (T2DM) and chronic obstructive pulmonary disease (COPD). We compared the risk of all-cause mortality between metformin users and nonusers. METHODS: We conducted a retrospective cohort study for patients with T2DM and COPD who were enrolled between January 1, 2000 and June 30, 2012. Individuals with exacerbated symptoms who were hospitalized or sent to the emergency department (ED) were identified as having exacerbated COPD; outpatient claims were identified as having stable COPD. A total of 40,597 metformin users and 39,529 nonusers comprised the cohort of stable COPD; 14,001 metformin users and 21,613 nonusers comprised the cohort of exacerbated COPD. Users and nonusers were matched using propensity score (1:1). Our primary outcome was all-cause mortality. RESULTS: A total of 19,505 metformin users were matched to 19,505 nonusers in the cohort of diabetes with stable COPD. The mean follow-up time was 3.91 years. All-cause mortality was reported in 1326 and 1609 metformin users and nonusers, respectively. After multivariate adjustment, metformin users had lower risk of mortality (adjusted hazard ratio [aHR] = 0.84, p < 0.0001). Metformin users had significantly lower risk of noncardiovascular death (aHR = 0.86, p = 0.0008). A total of 7721 metformin users were matched to 7721 nonusers in the cohort of diabetes with exacerbated COPD. The mean follow-up time was 3.18 years. All-cause mortality was reported in 1567 and 1865 metformin users and nonusers, respectively. After multivariate adjustment, metformin users had significantly lower risk of mortality (aHR = 0.89, p = 0.002) and cardiovascular death (aHR = 0.70, p = 0.01). CONCLUSION: This large-series, nationwide cohort study demonstrated that metformin use could significantly lower the risk of all cause mortality in patients with T2DM and either stable or exacerbated COPD. PMID- 30286139 TI - A multispectral imaging approach integrated into the study of Late Antique textiles from Egypt. AB - This work explores the use of multispectral imaging (MSI) techniques applied to the investigation of Late Antique (c. 250-800 AD) textiles found in Egypt. Although the use of these techniques is well-established in the study of polychrome surfaces, they have only been sparingly and often unsystematically applied to the investigation of textiles. The aim of this work is therefore to bridge this gap by showing how this non-invasive, relatively inexpensive and portable methodology can be used to map the photoluminescence and reflective characteristics of textiles under different wavelengths of light, and to provide qualitative and holistic insights into the chemical nature of the materials that compose them. Standardised acquisition and post-processing methods were applied to produce visible-reflected (VIS), ultraviolet-induced visible luminescence (UVL), infrared-reflected (IRR), infrared-reflected false colour (IRRFC), ultraviolet-reflected (UVR) and ultraviolet-reflected false colour (UVRFC) images that provided preliminary indications of the colourants used and their spatial distribution. This proved to be an important aid in planning more targeted and effective sampling strategies and facilitated comparisons between objects. Visible-induced visible luminescence (VIVL) and multiband-reflected (MBR) imaging were also explored for the first time with application to textiles, demonstrating their potential in mapping red and blue colourants respectively. The physical properties observed from all of these images were then related to the more detailed information provided by complementary non-invasive techniques, such as fibre optic reflectance spectroscopy (FORS), and micro-invasive approaches, such as high-performance liquid chromatography mass spectrometry (HPLC-MS). Guidelines towards the interpretation of complex MSI images and a discussion of the potential and limitations of relating multispectral data to chemical properties are presented. An important result of this work is the delineation of a protocol, which combines optical microscopy (OM), MSI, FORS and HPLC-MS and shows a high degree of potential, not only for the investigation of Late Antique textiles but for textiles in museum and historic collections generally. PMID- 30286140 TI - miR-125b regulates chemotaxis and survival of bone marrow derived granulocytes in vitro and in vivo. AB - The evolutionary conserved miR-125b is highly expressed in hematopoietic stem cells (HSC) enhancing self-renewal and survival. Accordingly, over-expression of miR-125b in HSC may induce myeloproliferative neoplasms and leukemia with long latency. During hematopoietic cell maturation miR-125b expression decreases, and the function of miR-125b in mature granulocytes is not yet known. We here use transplantation of miR-125b over-expressing HSC into syngeneic hosts to generate and analyse miR-125b over-expressing granulocytes. Under steady state conditions, miR-125b over-expression inhibits granulocytic chemotaxis and LPS- but not PMA- and TNFalpha- induced cell death. Inflammatory signals modulate the effects of miR-125b over-expression as demonstrated in a sterile peritonitis and a polymicrobial sepsis model. In particular, survival of mice with miR-125b over expressing granulocytes is significantly reduced as compared to controls in the polymicrobial sepsis model. These data demonstrate inflammation dependent effects of miR-125b in granulocytes and may point to therapeutic intervention strategies in the future. PMID- 30286141 TI - Effect of dietary polyunsaturated fatty acid and antioxidant supplementation on the transcriptional level of genes involved in lipid and energy metabolism in swine. AB - Porcine fat traits depend mostly on the interaction between nutritional and genetic factors. However, the pathways and biological processes influenced by this interaction are still poorly known in pigs, although they can have a huge impact on meat quality traits. The present research provides new knowledge insight into the effect of four diets (D1 = standard diet; D2 = linseed supplementation; D3 = linseed, vitamin E and selenium supplementation; D4 = linseed and plant-derived polyphenols supplementation) on the expression of 24 candidate genes selected for their role in lipid and energy metabolism. The data indicated that 10 out of 24 genes were differentially expressed among diets, namely ACACA, ADIPOQ, ADIPOR1, CHREBP (MLXPL), ELOVL6, FASN, G6PD, PLIN2, RXRA and SCD. Results from the univariate analysis displayed an increased expression of ACACA, ADIPOQ, ADIPOR1, CHREBP, ELOVL6, FASN, PLIN2, RXRA and SCD in D4 compared to D2. Similarly, ACACA, ADIPOQ, ADIPOR1, ELOVL6 and SCD were highly expressed in D4 compared to D3, while no differences were observed in D2-D3 comparison. Moreover, an increased expression of G6PD and ELOVL6 genes in D4 compared to D1 was observed. Results from the multivariate analysis confirmed that D2 was not different from D3 and that ACACA, SCD and FASN expression made D4 different from D2 and D3. Comparing D4 and D1, the expression levels of ELOVL6 and ACACA were the most influenced. This research provides evidence that the addition of both n-3 PUFA and polyphenols, derived from linseed, grape-skin and oregano supplementation in the diets, stimulates the expression of genes involved in lipogenesis and in oxidative processes. Results evidenced a greater effect on gene expression of the diet added with both plant extracts and n-3 PUFA, resulting in an increased expression of genes coding for fatty acid synthesis, desaturation and elongation in pig Longissimus thoracis muscle. PMID- 30286142 TI - Administration of CORM-2 inhibits diabetic neuropathy but does not reduce dyslipidemia in diabetic mice. AB - The antinociceptive effects of the carbon monoxide-releasing molecule tricarbonyldichlororuthenium (II) dimer (CORM-2) during chronic pain are well documented, but most of its possible side-effects remain poorly understood. In this work, we examine the impact of CORM-2 treatment on the lipoprotein profile and two main atheroprotective functions attributed to high-density lipoprotein (HDL) in a mouse model of type 1 diabetes while analyzing the effect of this drug on diabetic neuropathy. Streptozotocin (Stz)-induced diabetic mice treated with CORM-2 (Stz-CORM-2) or vehicle (Stz-vehicle) were used to evaluate the effect of this drug on the modulation of painful diabetic neuropathy using nociceptive behavioral tests. Plasma and tissue samples were used for chemical and functional analyses, as appropriate. Two main antiatherogenic properties of HDL, i.e., the ability of HDL to protect low-density lipoprotein (LDL) from oxidation and to promote reverse cholesterol transport from macrophages to the liver and feces in vivo (m-RCT), were also assessed. Stz-induced diabetic mice displayed hyperglycemia, dyslipidemia and pain hypersensitivity. The administration of 10 mg/kg CORM-2 during five consecutive days inhibited allodynia and hyperalgesia and significantly ameliorated spinal cord markers (Cybb and Bdkrb1expression) of neuropathic pain in Stz mice, but it did not reduce the combined dyslipidemia shown in Stz-treated mice. Its administration to Stz-treated mice led to a significant increase in the plasma levels of cholesterol (~ 1.4-fold vs. Ctrl, ~ 1.3- fold vs. Stz-vehicle; p < 0.05) and was attributed to significant elevations in both non-HDL (~ 1.8-fold vs. Ctrl; ~ 1.6-fold vs. Stz-vehicle; p < 0.05) and HDL cholesterol (~ 1.3-fold vs. Ctrl, ~ 1.2-fold vs. Stz-vehicle; p < 0.05). The increased HDL in plasma was not accompanied by a commensurate elevation in m-RCT in Stz-CORM-2 compared to Stz-vehicle mice; instead, it was worsened as revealed by decreased [3H]-tracer trafficking into the feces in vivo. Furthermore, the HDL mediated protection against LDL oxidation ex vivo shown by the HDL isolated from Stz-CORM-2 mice did not differ from that obtained in Stz-vehicle mice. In conclusion, the antinociceptive effects produced by a high dose of CORM-2 were accompanied by antioxidative effects but were without favorable effects on the dyslipidemia manifested in diabetic mice. PMID- 30286143 TI - Tumorigenicity-associated characteristics of human iPS cell lines. AB - Human induced pluripotent stem cells (hiPSCs) represent promising raw materials of human cell-based therapeutic products (hCTPs). As undifferentiated hiPSCs exhibit intrinsic tumorigenicity properties that enable them to form teratomas, hCTPs containing residual undifferentiated hiPSCs may cause tumor formation following transplantation. We first established quantitative and sensitive tumorigenicity testing of hiPSCs dissociated into single cells using NOD/Shi-scid IL2Rgammanull (NOG) mice by inhibiting apoptosis of hiPSCs with a Rho kinase inhibitor. To examine different features in tumorigenicity of various hiPSCs, 10 commonly available hiPSC lines were subjected to in vivo tumorigenicity testing. Transplanted hiPSC lines showed remarkable variation in tumor incidence, formation latency, and volumes. Most of the tumors formed were classified as immature teratomas. However, no signs of malignancies, such as carcinoma and sarcoma, were recognized in the tumors. Characteristics associated tumorigenicity of hiPSCs were investigated with microarray analysis, karyotype analysis, and whole exome sequencing. Gene expression profiling and pathway analysis supported different features of hiPSC lines in tumorigenicity. hiPSC lines showed chromosomal abnormalities in some lines and 61-77 variants of cancer-related genes carrying effective nonsynonymous mutations, which were confirmed in the COSMIC databases. In this study, the chromosomal abnormalities and cancer-related gene mutations observed in hiPSC lines did not lead to the malignancy of tumors derived from hiPSCs. Our results suggest that the potential tumorigenicity risk of hCTPs containing residual undifferentiated hiPSCs is dependent on not only amounts of undifferentiated hiPSCs but also features of the cell lines used as raw materials, a finding that should be considered from the perspective of quality of hCTPs used. PMID- 30286145 TI - Tracheal tubes lubricated with water to reduce sore throat after intubation: A randomized non-inferiority trial. AB - BACKGROUND: Sore throat is common after tracheal intubation. Water can be used to lubricate tracheal tubes, but its benefit has not been validated. We thus did a randomised non-inferiority trial to test the hypothesis that a tube lubricated with water does not reduce sore throat after tracheal intubation. METHODS: We randomized female or male patients (n = 296) undergoing surgery in the ears or eyes to receive either a tube lubricated with water or a tube without lubrication for intubation. We assessed sore throat at 0, 2, 4, and 24 h after surgery; pharyngeal injury at 2 and 24 h after surgery; and respiratory infections within 7 days after surgery. For the incidence of sore throat within 24 h after surgery (primary outcome), the two-sided 90% confidence interval of the risk difference was compared with the prespecified non-inferiority margin of 15%. Other outcomes were analyzed with two-sided superiority tests. RESULTS: The incidence of sore throat within 24 h after surgery was 80/147 (54.4%) in the non-lubricated tube group and 83/149 (55.7%) in the water-lubricated tube group (risk difference 1.3%, 90% confidence interval -10.9% to 8.3%). Because the confidence interval was below the non-inferiority margin, the incidence of sore throat was not higher in the non-lubricated tube group than in the water-lubricated tube group. There was no significant association between groups in the sore throat, pharyngeal injury, and respiratory infection at each assessment time. CONCLUSIONS: The tube lubricated with water did not reduce sore throat and pharyngeal injury after tracheal intubation compared to the tube without lubrication. PMID- 30286144 TI - Non-pharmacological interventions for the improvement of post-stroke activities of daily living and disability amongst older stroke survivors: A systematic review. AB - Globally, stroke remains a leading cause of death and disability, with older adults disproportionately affected. Numerous non-pharmacological stroke rehabilitation approaches are in use to address impairments, but their efficacy in older persons is largely unknown. This systematic review examined the evidence for such interventions as part of the Optimal Evidence-Based Non-Drug Therapies in Older Persons (ONTOP) project conducted under an European Union funded project called the Software Engine for the Assessment and Optimisation of Drug and Non Drug Therapies in Older Persons (SENATOR) [http://www.senator-project.eu]. A Delphi panel of European geriatric experts agreed activities of daily living and disability to be of critical importance as stroke rehabilitation outcomes. A comprehensive search strategy was developed and five databases (Pubmed, CINAHL, Embase, PsycInfo and Cochrane Database of Systematic Reviews) searched for eligible systematic reviews. Primary studies meeting our criteria (non pharmacologic interventions, involving stroke survivors aged >=65 years, assessing activities of daily living and/or disability as outcome) were then identified from these reviews. Eligible papers were double reviewed, and due to heterogeneity, narrative analysis performed. Cochrane risk of bias and GRADE assessment tools were used to assess bias and quality of evidence, allowing us to make recommendations regarding specific non-pharmacologic rehabilitation in older stroke survivors. In total, 72 primary articles were reviewed spanning 14 types of non-pharmacological intervention. Non-pharmacological interventions based on physiotherapy and occupational therapy techniques improved activities of daily living amongst older stroke survivors. However, no evidence was found to support use of any non-pharmacological approach to benefit older stroke survivors' disability. Evidence was limited by poor study quality and the small number of studies targeting older stroke survivors. We recommend future studies explore such interventions exclusively in older adult populations and improve methodological and outcome reporting. PMID- 30286146 TI - Reward-associated distractors can harm cognitive performance. AB - When people carry out cognitive tasks, they sometimes suffer from distractions, that is, drops in performance that occur close in time to task-irrelevant stimuli. In this research, we examine how the pursuit of rewards contributes to distractions. In two experiments, participants performed a math task (in which they could earn monetary rewards vs. not) while they were exposed to task irrelevant stimuli (that were previously associated with monetary rewards vs. not). In Experiment 1, irrelevant cues that were previously associated with rewards (vs. not) impaired performance. In Experiment 2, this effect was only replicated when these reward-associated distractors appeared relatively early during task performance. While the results were thus somewhat mixed, they generally support the idea that reward associations can augment the negative effect of distractors on performance. PMID- 30286148 TI - Judgements of a speaker's personality are correlated across differing content and stimulus type. AB - It has previously been shown that first impressions of a speaker's personality, whether accurate or not, can be judged from short utterances of vowels and greetings, as well as from prolonged sentences and readings of complex paragraphs. From these studies, it is established that listeners' judgements are highly consistent with one another, suggesting that different people judge personality traits in a similar fashion, with three key personality traits being related to measures of valence (associated with trustworthiness), dominance, and attractiveness. Yet, particularly in voice perception, limited research has established the reliability of such personality judgements across stimulus types of varying lengths. Here we investigate whether first impressions of trustworthiness, dominance, and attractiveness of novel speakers are related when a judgement is made on hearing both one word and one sentence from the same speaker. Secondly, we test whether what is said, thus adjusting content, influences the stability of personality ratings. 60 Scottish voices (30 females) were recorded reading two texts: one of ambiguous content and one with socially relevant content. One word (~500 ms) and one sentence (~3000 ms) were extracted from each recording for each speaker. 181 participants (138 females) rated either male or female voices across both content conditions (ambiguous, socially relevant) and both stimulus types (word, sentence) for one of the three personality traits (trustworthiness, dominance, attractiveness). Pearson correlations showed personality ratings between words and sentences were strongly correlated, with no significant influence of content. In short, when establishing an impression of a novel speaker, judgments of three key personality traits are highly related whether you hear one word or one sentence, irrespective of what they are saying. This finding is consistent with initial personality judgments serving as elucidators of approach or avoidance behaviour, without modulation by time or content. All data and sounds are available on OSF (osf.io/s3cxy). PMID- 30286149 TI - Germ cell desquamation-based testis regression in a seasonal breeder, the Egyptian long-eared hedgehog, Hemiechinus auritus. AB - Testes of seasonally breeding species experience a severe functional regression before the non-breeding period, which implies a substantial mass reduction due to massive germ-cell depletion. Two alternative mechanisms of seasonal germ-cell depletion have been described in mammals, apoptosis and desquamation (sloughing), but their prevalence has not been determined yet due to reduced number of species studied. We performed a morphological, hormonal, and molecular study of the mechanism of seasonal testicular regression in males of the Egyptian long eared hedgehog (Hemiechinus auritus). Our results show that live, non-apoptotic, germ cells are massively depleted by desquamation during the testis regression process. This is concomitant with both decreased levels of serum testosterone and irregular distribution of the cell-adhesion molecules in the seminiferous epithelium. The inactive testes maintain some meiotic activity as meiosis onset is not halted and spermatocytes die by apoptosis at the pachytene stage. Our data support the notion that apoptosis is not the major testis regression effector in mammals. Instead, desquamation appears to be a common mechanism in this class. PMID- 30286147 TI - Storage fidelity for sequence memory in the hippocampal circuit. AB - Episodic memories have been suggested to be represented by neuronal sequences, which are stored and retrieved from the hippocampal circuit. A special difficulty is that realistic neuronal sequences are strongly correlated with each other since computational memory models generally perform poorly when correlated patterns are stored. Here, we study in a computational model under which conditions the hippocampal circuit can perform this function robustly. During memory encoding, CA3 sequences in our model are driven by intrinsic dynamics, entorhinal inputs, or a combination of both. These CA3 sequences are hetero associated with the input sequences, so that the network can retrieve entire sequences based on a single cue pattern. We find that overall memory performance depends on two factors: the robustness of sequence retrieval from CA3 and the circuit's ability to perform pattern completion through the feedforward connectivity, including CA3, CA1 and EC. The two factors, in turn, depend on the relative contribution of the external inputs and recurrent drive on CA3 activity. In conclusion, memory performance in our network model critically depends on the network architecture and dynamics in CA3.

AB - We have optimized the design and imaging procedures, to clearly resolve the malaria parasite in Giemsa-stained thin blood smears, using simple low-cost cellphone-based microscopy with oil immersion. The microscope uses a glass ball as the objective and the phone camera as the tube lens. Our optimization includes the optimal choice of the ball lens diameter, the size and the position of the aperture diaphragm, and proper application of immersion, to achieve diagnostic capacity in a wide field of view. The resulting system is potentially applicable to low-cost in-the-field optical diagnostics of malaria as it clearly resolves micron-sized features and allows for analysis of parasite morphology in the field of 50 * 50 MUm, and parasite detection in the field of at least 150 * 150 MUm. PMID- 30286151 TI - T Cell Leukemia/Lymphoma 1A is essential for mouse epidermal keratinocytes proliferation promoted by insulin-like growth factor 1. AB - T Cell Leukemia/Lymphoma 1A is expressed during B-cell differentiation and, when over-expressed, acts as an oncogene in mouse (Tcl1a) and human (TCL1A) B-cell chronic lymphocytic leukemia (B-CLL) and T-cell prolymphocytic leukemia (T-PLL). Furthermore, in the murine system Tcl1a is expressed in the ovary, testis and in pre-implantation embryos, where it plays an important role in blastomere proliferation and in embryonic stem cell (ESC) proliferation and self-renewal. We have also observed that Tcl1-/- adult mice exhibit alopecia and deep ulcerations. This finding has led us to investigate the role of TCL1 in mouse skin and hair follicles. We have found that TCL1 is expressed in the proliferative structure (i.e. the secondary hair germ) and in the stem cell niche (i.e. the bulge) of the hair follicle during regeneration phase and it is constitutively expressed in the basal layer of epidermis where it is required for the correct proliferative differentiation program of the keratinocytes (KCs). Taking advantage of the murine models we have generated, including the Tcl1-/- and the K14-TCL1 transgenic mouse, we have analysed the function of TCL1 in mouse KCs and the molecular pathways involved. We provide evidence that in the epidermal compartment TCL1 has a role in the regulation of KC proliferation, differentiation, and apoptosis. In particular, the colony-forming efficiency (CFE) and the insulin-like growth factor 1 (IGF1)-induced proliferation are dramatically impaired, while apoptosis is increased, in KCs from Tcl1-/- mice when compared to WT. Moreover, the expression of differentiation markers such as cytokeratin 6 (KRT6), filaggrin (FLG) and involucrin (IVL) are profoundly altered in mutant mice (Tcl1-/-). Importantly, by over-expressing TCL1A in basal KCs of the K14-TCL1 transgenic mouse model, we observed a significant rescue of cell proliferation, differentiation and apoptosis of the mutant phenotype. Finally, we found TCL1 to act, at least in part, via increasing phospho-ERK1/2 and decreasing phospho-P38 MAPK. Hence, our data demonstrate that regulated levels of Tcl1a are necessary for the correct proliferation and differentiation of the interfollicular KCs. PMID- 30286152 TI - Rapid identification of Bactrocera zonata (Dip.: Tephritidae) using TaqMan real time PCR assay. AB - Tephritid fruit flies are ranked as one of the most damaging groups of insect pests. Morphological identification of fruit flies is mainly performed on adults due to the lack of adequate identification keys for immature stages. The peach fruit fly, Bactrocera zonata (Saunders), infests some of the principal commercial fruits and vegetables. It is, therefore important to avert its global dispersal, particularly by accurately identifying this species at ports of entry. In this study, a TaqMan real-time polymerase chain reaction (PCR) was developed for the accurate identification and sensitive detection of the peach fruit fly. A novel set of primers and probe were designed to specifically identify the mitochondrial cytochrome oxidase I (COI) gene. All specimens of peach fruit fly (including various life stages) were detected, and no cross reactivity with other tested tephritids were observed. Since this assay performed equally well with crushed insects and purified DNA, we note added efficiency by eliminating DNA extraction step. Considering the speed, specificity as well as sensitivity of the assay, Taqman real-time PCR can be used as a swift and specific method for pest species at ports of entry. PMID- 30286153 TI - Incidence and outcome of weaning from mechanical ventilation in medical wards at Thammasat University Hospital. AB - BACKGROUND: Weaning from mechanical ventilation is classified as simple, difficult, or prolonged according to weaning process. Theoretically, simple weaning group usually has better clinical outcomes than non-simple group; however, the results of previous studies were still inconsistent. OBJECTIVES: The purpose of the study was to determine the incidence, predictors, and outcomes of ventilator weaning and causes of weaning failure. METHODS: A prospective observational study was performed between June and December 2013 in all patients (n = 164) who required mechanical ventilation with endotracheal intubation in medical wards at Thammasat University Hospital, Thailand. Duration of weaning, causes of weaning failure, extubation, reintubation, tracheostomy, number of ventilator-free days within 28 days, length of hospital stay, and hospital mortality were measured. RESULTS: 103 patients were eligible for final analysis. Mean +/- SD age was 65.1+/-17.5 years and 55.3% were males. The incidences of simple, difficult and prolonged weaning were 46.6%, 36.9% and 16.5%, respectively. The mortality rates for simple, difficult, and prolonged weaning were 0%, 10.5% and 23.5% (p = 0.006), respectively. The 3 causes of weaning failure in non-simple weaning were bronchospasm, pneumonia, and malnutrition. CONCLUSIONS: Non-simple weaning increased mortality. Bronchospasm, pneumonia, and malnutrition were key risk factors for weaning failure. Strategies are needed to minimize their effects. PMID- 30286155 TI - DECORE-21: Assessment of occupational stress in police. Confirmatory factor analysis of the original model. AB - There is scarce research on stress in Spanish police officers and on the use of instruments to assess this construct in this professional group. In Spain, the DECORE questionnaire has been one of the most used. Nevertheless, it had not been previously applied to police officers. The aim of this study was to analyze both the construct validity and the reliability of the original model of 44 items. A cross-sectional design and a non-probabilistic quota sampling were used. A total of 223 Spanish police officers participated. 202 police personnel were men (90.6%) and 21 were women (9.4%). The average age was 41 years old (SD = 7.52). These police officers answered the DECORE questionnaire. Confirmatory Factor Analysis was carried out. The results showed an unsatisfactory adjustment using the original model of 44 items. A final solution of 21 items and four factors was formulated with both suitable validity and reliability indexes. In this model, 23 items that did not weigh highly in any of the four factors were removed. The DECORE-21 questionnaire is recommended to assess work-related stress in police officers. PMID- 30286154 TI - BRCA1/2 mutations are not a common cause of malignant melanoma in the Polish population. AB - The association of BRCA1/2 mutations with melanoma is not completely determined; the interpretation of variants of unknown significance is also problematic. To evaluate these issues we explored the molecular basis of melanoma risk by performing whole-exome sequencing on a cohort of 96 unrelated Polish early-onset melanoma patients and targeted sequencing of BRCA1/2 genes on additional 30 melanoma patients with familial aggregation of breast and other cancers. Sequencing was performed on peripheral blood. We evaluated MutationTaster, Polyphen2, SIFT, PROVEAN algorithms, analyzed segregation with cancer disease (in both families with identified BRCA2 variants) and in one family performed LOH (based on 2 primary tumors). We found neither pathogenic mutations nor variants of unknown significance within BRCA1. We identified two BRCA2 variants of unknown significance: c.9334G>A and c.4534 C>T. Disease allele frequency was evaluated by genotyping of 1230 consecutive melanoma cases, 5000 breast cancer patients, 3500 prostate cancers and 9900 controls. Both variants were found to be absent among unselected cancer patients and healthy controls. The MutationTaster, Polyphen2 and SIFT algorithms indicate that c.9334G>A is a damaging variant. Due to lack of tumour tissue LOH analysis could not be performed for this variant. The variant segregated with the disease. The c.4534 C>T variant did not segregate with disease, there was no LOH of the variant. The c.9334G>A variant, classified as a rare variant of unknown significance, on current evidence may predisposes to cancers of the breast, prostate and melanoma. Functional studies to describe how the DNA change affects the protein function and a large multi-center study to evaluate its penetrance are required. PMID- 30286156 TI - Application of insulin signaling to predict insect growth rate in Maruca vitrata (Lepidoptera: Crambidae). AB - Insect growth is influenced by two major environmental factors: temperature and nutrient. These environmental factors are internally mediated by insulin/insulin like growth factor signal (IIS) to coordinate tissue or organ growth. Maruca vitrata, a subtropical lepidopteran insect, migrates to different climate regions and feeds on various crops. The objective of this study was to determine molecular tools to predict growth rate of M. vitrata using IIS components. Four genes [insulin receptor (InR), Forkhead Box O (FOXO), Target of Rapamycin (TOR), and serine-threonine protein kinase (Akt)] were used to correlate their expression levels with larval growth rates under different environmental conditions. The functional association of IIS and larval growth was confirmed because RNA interference of these genes significantly decreased larval growth rate and pupal weight. Different rearing temperatures altered expression levels of these four IIS genes and changed their growth rate. Different nutrient conditions also significantly changed larval growth and altered expression levels of IIS components. Different local populations of M. vitrata exhibited significantly different larval growth rates under the same nutrient and temperature conditions along with different expression levels of IIS components. Under a constant temperature (25 degrees C), larval growth rates showed significant correlations with IIS gene expression levels. Subsequent regression formulas of expression levels of four IIS components against larval growth rate were applied to predict growth patterns of M. vitrata larvae reared on different natural hosts and natural local populations reared on the same diet. All four formulas well predicted larval growth rates with some deviations. These results indicate that the IIS expression analysis explains the growth variation at the same temperature due to nutrient and genetic background. PMID- 30286157 TI - Social network properties predict chronic aggression in commercial pig systems. AB - Post-mixing aggression in pigs is a harmful and costly behaviour which negatively impacts both animal welfare and farm efficiency. There is vast unexplained variation in the amount of acute and chronic aggression that dyadic behaviours do not fully explain. This study hypothesised that certain pen-level network properties may improve prediction of lesion outcomes due to the incorporation of indirect social interactions that are not captured by dyadic traits. Utilising current SNA theory, we investigate whether pen-level network properties affect the number of aggression-related injuries at 24 hours and 3 weeks post-mixing (24hr-PM and 3wk-PM). Furthermore we compare the predictive value of network properties to conventional dyadic traits. A total of 78 pens were video recorded for 24hr post-mixing. Each aggressive interaction that occurred during this time period was used to construct the pen-level networks. The relationships between network properties at 24hr and the pen level injuries at 24hr-PM and 3wk-PM were analysed using mixed models and verified using permutation tests. The results revealed that network properties at 24hr could predict long term aggression (3wk PM) better than dyadic traits. Specifically, large clique formation in the first 24hr-PM predicted fewer injuries at 3wk-PM and high betweenness centralisation at 24hr-PM predicted increased rates of injury at 3wk-PM. This study demonstrates that network properties present during the first 24hr-PM have predictive value for chronic aggression, and have potential to allow identification and intervention for at risk groups. PMID- 30286158 TI - Isotope values of the bioavailable strontium in inland southwestern Sweden-A baseline for mobility studies. AB - The inland area of southwestern Sweden is well known for its well-preserved archaeological animal and human remains dating back to the Mesolithic and Neolithic (10000-4000 and 4000-1700 BC). They allow application of multiple bioarchaeological methods, giving insights into various and complementary aspects of prehistoric human life, as well as economic and social structures. One important aspect concerns human mobility and its relation to social networks and to circulation of objects. Here, strontium isotope analysis plays a crucial role. The present study aims to construct a strontium isotope baseline of southwestern Sweden with considerably greater coverage and higher resolution than previously published data. As the region has been affected by glacial events, the relation between bedrock geology and isotope signals of the bioavailable strontium in such areas is given special attention. We determined strontium isotope ratios for 61 water and five archaeological animal samples, and combined the data with previous measurements of two water and 21 non-domestic faunal samples. The results reveal a complex pattern. Several areas with distinct baseline ranges can be distinguished, although with overlaps between some of them. Overall, the bioavailable strontium isotope signals mirror the basement geology of the region. The highest ratios occur in the geologically oldest eastern parts of the Precambrian terrain, while lower ratios are found in the western part, and the lowest ratios occur in the youngest Paleozoic areas. At the same time, there are minor deviations compared to the underlying bedrock, due to glacial transport, overlying sediments, and local intrusions of younger rocks. The background data set now available allows for more nuanced and detailed interpretations of human and animal mobility in the region, in particular by identification of subregions with differing strontium isotope ratios within the Precambrian province. Also, we can now identify long distance mobility with greater confidence. PMID- 30286159 TI - Impact of pre-existing treatment with statins on the course and outcome of tick borne encephalitis. AB - OBJECTIVES: Although statins have anti-inflammatory and potentially also antimicrobial (including antiviral) activity, their therapeutic impact on infectious diseases is controversial. In this study, we evaluated whether pre existing statin use influenced the course and outcome of tick-borne encephalitis. METHODS: To assess the influence of statin usage on the severity of acute illness and the outcome of tick-borne encephalitis, univariate and multivariable analyses were performed for 700 adult patients with tick-borne encephalitis of whom 77 (11%) were being treated with statins, and for 410 patients of whom 53 (13%) were receiving statins, respectively. RESULTS: Multivariable analyses found no statistically significant association between statin usage and having a milder acute illness. There was also no statistically significant benefit with respect to a favorable outcome defined by the absence of post-encephalitic syndrome (ORs for a favorable outcome at 6 months was 0.96, 95% CI: 0.46-2.04, P = 0.926; at 12 months 0.29, 95% CI: 0.06-1.33, P = 0.111; at 2-7 years after acute illness 0.44, 95% CI: 0.09-2.22, P = 0.321), by a reduction in the frequency of six nonspecific symptoms (fatigue, myalgia/arthralgia memory disturbances, headache, concentration disturbances, irritability) occurring during the 4 week period before the last examination, or by higher SF-36 scores in any of the eight separate domains of health as well as in the physical and mental global overall component. Furthermore, there were no significant differences between patients receiving statins and those who were not in the cerebrospinal fluid or serum levels for any of the 24 cytokines/chemokines measured. CONCLUSIONS: In this observational study, we could not prove that pre-existing use of statins affected either the severity of the acute illness or the long-term outcome of tick-borne encephalitis. PMID- 30286160 TI - HIV-1C proviral DNA for detection of drug resistance mutations. AB - BACKGROUND: Using HIV proviral DNA as a template may be suitable for initial detection of transmitted drug resistance mutations (TDRMs) as it is easy to handle and less expensive compared to RNA. However, existing literatures which are mainly focused on HIV-1B subtypes DNA extracted from PBMCs revealed controversial findings ranging from the detection of significantly lower or higher mutations in proviral DNA compared to historic viral RNA. Thus, to verify whether viral RNA or proviral DNA has improved sensitivity in detecting transmitted genotypic drug resistance mutations paired viral RNA and proviral DNA (which is directly extracted from stored whole blood) samples were tested from Ethiopian antiretroviral naive HIV-1C infected subjects. METHODS: In the present comparative study the frequency of TDR mutations was assessed in paired samples of viral RNA and proviral DNA (extracted directly from stored whole blood) of HIV 1C infected treatment naive patients and interpreted using the 2009 WHO drug resistance surveillance mutation lists, Stanford University drug resistance data base and International Antiviral Society-USA mutation lists. RESULTS: High agreement in rate of TDR between the two compartments was observed using the WHO mutation lists. While mutations G190A and E138A were concurrently found in both compartments, others such as G73S on PR and A62V, M184I, M230I on RT were identified in proviral DNA only. All signature mutations seen in viral RNA were not missed in proviral DNA. CONCLUSIONS: The concordance of major genotype drug resistance mutation between RNA and proviral DNA in treatment naive patients suggests that proviral DNA might be an alternative approaches for an initial assessment of drug resistance prior to initiation of antiretroviral therapy using the WHO mutations lists in resource-limited countries. However, the clinical importance of TDRMs observed only in proviral DNA in terms of being a risk factor for virologic failure and whether they limit future treatment options needs additional investigation using more sensitive sequencing approaches such as Next Generation Sequencing (NGS). PMID- 30286161 TI - Understanding women's, caregivers', and providers' experiences with home-based records: A systematic review of qualitative studies. AB - Mothers, caregivers, and healthcare providers in 163 countries have used paper and electronic home-based records (HBRs) to facilitate primary care visit. These standardized records have the potential to empower women, improve the quality of care for mothers and children and reduce health inequities. This review examines experiences of women, caregivers and providers with home-based records for maternal and child health and seeks to explore the feasibility, acceptability, affordability and equity of these interventions. We systematically searched MEDLINE, MEDLINE In-Process, MEDLINE Ahead of Print, Embase, CINAHL, ERIC, and PsycINFO for articles that were published between January 1992 and December 2017. We used the CASP checklist to assess study quality, a framework analysis to support synthesis, and GRADE-CERQual to assess the confidence in the key findings. Of 7,904 citations, 19 studies met our inclusion criteria. In these studies, mothers, caregivers and children shared HBR experiences in relation to maternal and child health which facilitated the monitoring of immunisations and child growth and development. Participants' reports of HBRs acting as a point of commonality between patient and provider offer an explanation for their perceptions of improved communication and patient-centered care, and enhanced engagement and empowerment during pregnancy and childcare. Healthcare providers and nurses reported that the home-based record increased their feeling of connection with their patients. Although there were concerns around electronic records and confidentiality, there were no specific concerns reported for paper records. Mothers and other caregivers see home based records as having a pivotal role in facilitating primary care visits and enhancing healthcare for their families. The records' potential could be limited by users concerns over confidentiality of electronic home-based records, or shortcomings in their design. Health systems should seize the opportunity HBRs provide in empowering women, especially in the contexts of lower literacy levels and weak health care delivery systems. PMID- 30286162 TI - Functional analysis of a triplet deletion in the gene encoding the sodium glucose transporter 3, a potential risk factor for ADHD. AB - Sodium-glucose transporters (SGLT) belong to the solute carrier 5 family, which is characterized by sodium dependent transport of sugars and other solutes. In contrast, the human SGLT3 (hSGLT3) isoform, encoded by SLC5A4, acts as a glucose sensor that does not transport sugar but induces membrane depolarization by Na+ currents upon ligand binding. Whole-exome sequencing (WES) of several extended pedigrees with high density of attention-deficit/hyperactivity disorder (ADHD) identified a triplet ATG deletion in SLC5A4 leading to a single amino acid loss (DeltaM500) in the hSGLT3 protein imperfectly co-segregating with the clinical phenotype of ADHD. Since mutations in homologous domains of hSGLT1 and hSGLT2 were found to affect intestinal and renal function, respectively, we analyzed the functional properties of hSGLT3[wt] and [DeltaM500] by voltage clamp and current clamp recordings from cRNA-injected Xenopus laevis oocytes. The cation conductance of hSGLT3[wt] was activated by application of glucose or the specific agonist 1-desoxynojirimycin (DNJ) as revealed by inward currents in the voltage clamp configuration and cell depolarization in the current clamp mode. Almost no currents and changes in membrane potential were observed when glucose or DNJ were applied to hSGLT3[DeltaM500]-injected oocytes, demonstrating a loss of function by this amino acid deletion in hSGLT3. To monitor membrane targeting of wt and mutant hSGLT3, fusion constructs with YFP were generated, heterologously expressed in Xenopus laevis oocytes and analyzed for membrane fluorescence by confocal microscopy. In comparison to hSGLT3[wt] the fluorescent signal of mutant [DeltaM500] was reduced by 43% indicating that the mutant phenotype might mainly result from inaccurate membrane targeting. As revealed by homology modeling, residue M500 is located in TM11 suggesting that in addition to the core structure (TM1-TM10) of the transporter, the surrounding TMs are equally crucial for transport/sensor function. In conclusion, our findings indicate that the deletion [DeltaM500] in hSGLT3 inhibits membrane targeting and thus largely disrupts glucose-induced sodium conductance, which may, in interaction with other ADHD risk-related gene variants, influence the risk for ADHD in deletion carriers. PMID- 30286163 TI - Fas/FasL pathway and cytokines in keratinocytes in atopic dermatitis - Manipulation by the electromagnetic field. AB - BACKGROUND: Atopic dermatitis (AD) is one of the most frequent skin diseases. Changes of the keratinocytes functionality play a major role in the development of AD. For example, activation of the Fas (CD95)/FasL (CD178) pathway in AD does not lead to extensive apoptosis in skin. Binding of the Fas receptor to its protein ligand-FasL, which are present on the (AD)-modified keratinocytes, should result in the sequential induction of cell death, but there is no evidence of extensive apoptosis of these cells. This suggests that non-apoptotic mechanism of Fas/FasL pathway is commonly encountered, although not examined in the case of AD, phenomenon. An electromagnetic field, which was used to influence cultured cells in this study, can modulate proliferation, apoptosis, differentiation, and metabolism in various cells. OBJECTIVE: Here, we evaluate the possibility to manipulate the immune activation of AD keratinocytes and their response to the electromagnetic field, which was not tested before. METHODS: Keratinocytes isolated from the skin of healthy subjects (n = 20) and patients with atopic dermatitis (n = 20) as well as HaCaT and PCS-200-010 cell were exposed to the 900 MHz electromagnetic field for 60 minutes. Cytometric analysis of viability, Fas/FasL, p-ERK, p-p38 and p-JNK expression and Luminex analysis of cytokine concentration were performed in two-time points: 4 and 24 hours after the exposition. RESULTS: This research has shown upregulated Fas, FasL, p-ERK, p-p38, and p-JNK expression along with increased cytokine secretion (IL-1beta, IL-4, IL 8, IL-10, IL-12p70, IL-13, IL-17A, IL-31 and TNFalpha) by keratinocytes derived from the skin of patients with the AD when compared with healthy control. Exposure of keratinocyte cultures obtained from AD patients to EMF resulted in a decrease of 1beta, IL-4, IL-10, IL-12, I L-13, IL-17, IL-31 and TNFalpha levels. Keratinocytes derived from the skin of AD patients are characterized by elevated Fas and FasL expression when compared to healthy control. CONCLUSION: Apoptotic and nonapoptotic activation of the Fas/FasL-dependent signaling pathway may play a significant role in the pathogenesis of AD, by adjusting the local cytokine and chemokine environment at the site of inflammation. Moreover, the electromagnetic field exhibits strong immunomodulatory effects on AD-modified keratinocytes.

PMID- 30286165 TI - Efficient multi-task chemogenomics for drug specificity prediction. AB - Adverse drug reactions, also called side effects, range from mild to fatal clinical events and significantly affect the quality of care. Among other causes, side effects occur when drugs bind to proteins other than their intended target. As experimentally testing drug specificity against the entire proteome is out of reach, we investigate the application of chemogenomics approaches. We formulate the study of drug specificity as a problem of predicting interactions between drugs and proteins at the proteome scale. We build several benchmark datasets, and propose NN-MT, a multi-task Support Vector Machine (SVM) algorithm that is trained on a limited number of data points, in order to solve the computational issues or proteome-wide SVM for chemogenomics. We compare NN-MT to different state-of-the-art methods, and show that its prediction performances are similar or better, at an efficient calculation cost. Compared to its competitors, the proposed method is particularly efficient to predict (protein, ligand) interactions in the difficult double-orphan case, i.e. when no interactions are previously known for the protein nor for the ligand. The NN-MT algorithm appears to be a good default method providing state-of-the-art or better performances, in a wide range of prediction scenario that are considered in the present study: proteome-wide prediction, protein family prediction, test (protein, ligand) pairs dissimilar to pairs in the train set, and orphan cases. PMID- 30286166 TI - Methodological considerations in clinical outcomes assessment of pharmacy-based minor ailments management: A systematic review. AB - BACKGROUND: The accessibility of services within community pharmacies provides an ideal opportunity to manage minor ailments, yet over L1.1 billion is spent by the National Health Service (NHS) in the United Kingdom (UK) in managing minor ailments in high cost settings. There is a need to review the evidence base around clinical effectiveness of pharmacy-based management of minor ailments since the absence of such may lead to under-utilisation of pharmacy services and non-implementation of available pharmacy service models. This study aimed to systematically review the methodological approaches used to assess clinical outcomes of pharmacy-based management of minor ailments in the research literature. METHODS: A systematic review was conducted to identify relevant literature using the following databases: Medline, EMBASE, CINAHL, IPA, CRD, CDSR, and Google Scholar from publication year 2000 onwards. Studies were included if they evaluated clinical outcomes of pharmacy-based management of any minor ailments, with or without a comparator setting such as Emergency Departments (EDs) or general practices. Screening and selection of titles, abstracts and full texts followed by data extraction and quality assessment (QA) was conducted. Paired researchers, from the team, reviewed papers using a protocol based on the Preferred Reporting Items for Systematic Review and Meta Analysis Protocols (PRISMA-P). QA was undertaken using the Critical Appraisal Skills Programme (CASP). Reporting was conducted in accordance with PRISMA checklist and statements. RESULTS: A total of 19 studies were included. The majority of studies were observational, conducted in community pharmacies, and did not use a comparator participant group nor a comparator setting. Interventions included counselling, medicines supply and provision of advice on the management of minor ailments. One study used the randomised controlled trial (RCT) design with majority of the study utilising observational design. A range of clinical outcomes including symptom severity, pattern, resolution, and quality of life were reported. Methods used for the assessment of clinical outcomes were, overall, poorly reported. This included a lack of information on the development and validation of the data collection tools and the timing of baseline and follow up data collection. Adverse clinical outcomes data were collected by only seven studies. CONCLUSIONS: Currently, there are methodological limitations in the studies that have sought to assess clinical outcomes of pharmacy-based management of minor ailments. Such lack of high quality evidence may contribute to failings to shift care from high cost settings, such as EDs and general practices. Generation of high quality evidence is likely to influence public choices when seeking care for minor ailments. There is scope for development of a core outcomes set specific to minor ailments management and development of a validated methodology for measuring such outcomes in a research study. PMID- 30286167 TI - 4.1Ba is necessary for glutamatergic synapse formation in the sensorimotor circuit of developing zebrafish. AB - During the process of synapse formation, thousands of proteins assemble at prospective sites of cell-cell communication. Although many of these proteins have been identified, the roles they play in generating functional connections during development remain unknown. 4.1 scaffolding proteins have been implicated in synapse formation and maturation in vitro, but in vivo studies for some family members have suggested these proteins are not important for this role. We examined the role of family member 4.1B because it has been implicated in glutamatergic synaptogenesis, but has not been described in vivo. We identified two 4.1B genes in zebrafish, 4.1Ba and 4.1Bb, by sequence comparisons and synteny analysis. In situ hybridization shows these genes are differentially expressed, with 4.1Ba expressed primarily in the nervous system and 4.1Bb expressed in the nervous system and muscle, but not the spinal cord. We focused our studies on 4.1Ba in the spinal cord. 4.1Ba knockdown reduced the number of glutamatergic synapses at caudal primary motor neurons and caused an increase in the duration of touch-evoked coiling. These results suggest 4.1Ba is important for the formation of functional glutamatergic synapses in the developing zebrafish spinal cord.

AB - In the human retina, rod and cone cells detect incoming light with a molecule called rhodopsin. After rhodopsin molecules are activated (by photon impact), these molecules activate the rest of the signalling process for a brief period of time until they are deactivated by a multistage process. First, active rhodopsin is phosphorylated multiple times. Following this, they are further inhibited by the binding of molecules called arrestins. Finally, they decay into opsins. The time required for each of these stages becomes progressively longer, and each stage further reduces the activity of rhodopsin. However, while this deactivation process itself is well researched, the roles of the above stages in signal (and image) processing are poorly understood. In this paper, we will show that the activity of rhodopsin molecules during the deactivation process can be described as the fractional integration of an incoming signal. Furthermore, we show how this affects an image; specifically, the effect of fractional integration in video and signal processing and how it reduces noise and the improves adaptability under different lighting conditions. Our experimental results provide a better understanding of vertebrate and human vision, and why the rods and cones of the retina differ from the light detectors in cameras.

PMID- 30286170 TI - Effect of fenofibrate in 1113 patients at low-density lipoprotein cholesterol goal but high triglyceride levels: Real-world results and factors associated with triglyceride reduction. AB - Fibrates are used in patients with dyslipidemia and high cardiovascular risk. However, information regarding drug response to fibrate has been highly limited. We investigated treatment results and factors associated with triglyceride reduction after fenofibrate therapy using large-scale real-world data. Patients with one or more cardiovascular risk factors, at low-density lipoprotein cholesterol goal but with triglyceride level >=150 mg/dL, and undergoing treatment with fenofibrate 135-160 mg for the first time were included in this retrospective observational study. The outcome variable was the percentage changes of TG levels. The achievement rate of triglyceride <150 mg/dL was additionally analyzed. Factors associated with treatment results were also analyzed. Among 2546 patients who were initially screened, 1113 patients were enrolled (median age: 61 years; male: 71%). After median follow-up of 4 months, the median change in triglyceride was -60%, and 49% of the patients reached triglyceride <150 mg/dL. After adjusting for confounding variables, female sex, non-diabetic status, coronary artery disease, lower baseline triglyceride, and no statin use were identified to be independently associated with achievement of triglyceride <150 mg/dL. Among them, female sex, non-diabetic status, and coronary artery disease were also related to median or greater percentage reduction of triglyceride. In conclusion, only half of the study patients reached triglyceride levels <150 mg/dL after real-world fenofibrate therapy. This study indicates that more attention is needed on some subgroups to obtain optimal triglyceride levels when treating with fenofibrate. PMID- 30286171 TI - The translation, validity and reliability of the German version of the Fremantle Back Awareness Questionnaire. AB - BACKGROUND: The Fremantle Back Awareness Questionnaire (FreBAQ) claims to assess disrupted self-perception of the back. The aim of this study was to develop a German version of the FreBAQ (FreBAQ-G) and assess its test-retest reliability, its known-groups validity and its convergent validity with another purported measure of back perception. METHODS: The FreBaQ-G was translated following international guidelines for the transcultural adaptation of questionnaires. Thirty-five patients with non-specific CLBP and 48 healthy participants were recruited. Assessor one administered the FreBAQ-G to each patient with CLBP on two separate days to quantify intra-observer reliability. Assessor two administered the FreBaQ-G to each patient on day 1. The scores were compared to those obtained by assessor one on day 1 to assess inter-observer reliability. Known-groups validity was quantified by comparing the FreBAQ-G score between patients and healthy controls. To assess convergent validity, patient's FreBAQ-G scores were correlated to their two-point discrimination (TPD) scores. RESULTS: Intra- and Inter-observer reliability were both moderate with ICC3.1 = 0.88 (95%CI: 0.77 to 0.94) and 0.89 (95%CI: 0.79 to 0.94), respectively. Intra- and inter-observer limits of agreement (LoA) were 6.2 (95%CI: 5.0-8.1) and 6.0 (4.8 7.8), respectively. The adjusted mean difference between patients and controls was 5.4 (95%CI: 3.0 to 7.8, p<0.01). Patient's FreBAQ-G scores were not associated with TPD thresholds (Pearson's r = -0.05, p = 0.79). CONCLUSIONS: The FreBAQ-G demonstrated a degree of reliability and known-groups validity. Interpretation of patient level data should be performed with caution because the LoA were substantial. It did not demonstrate convergent validity against TPD. Floor effects of some items of the FreBAQ-G may have influenced the validity and reliability results. The clinimetric properties of the FreBAQ-G require further investigation as a simple measure of disrupted self-perception of the back before firm recommendations on its use can be made. PMID- 30286172 TI - Doctor's recommendations for psychosocial care: Frequency and predictors of recommendations and referrals. AB - BACKGROUND: A significant number of oncological patients are heavily burdened by psychosocial stress. Doctors recommending or referring their patients to psycho oncologists in the course of routine consultations can positively influence psycho-oncological care. The aim of this study was to analyze the frequency and predictors of such recommendations and to examine the use of these services by patients. METHODS: 4,020 cancer patients (mean age 58 years; 51% women) were evaluated in a multicenter, cross-sectional study in Germany. Data was gathered about doctors' referral practices, patients' utilization of psycho-oncological care services, and disease-related symptoms. The PHQ-9 depression scale and the GAD-7 anxiety scale were used to measure psychological burden. Descriptive data analysis was conducted on the basis of subgroup comparisons and multivariable analysis was done using binary logistical regression. RESULTS: 21.9% of the respondents reported having been given a recommendation or referral for psycho oncological care by a doctor within the course of their cancer diagnosis and treatment. This comprises 29.5% of the patients identified by screening as being psychologically burdened. Nearly half of the patients who received a recommendation or referral (49.8%) acted on it. Predictors for seeking out psycho oncological care included: patient desire (OR = 2.0), previous experience with psycho-oncological care (OR = 1.59), and female gender (OR = 1.57). Multivariable analysis indicated that patients' level of psychological burden (depression, anxiety) had no effect on whether doctors gave them a recommendation or referral. CONCLUSIONS: Along with examining the degree to which patients are burdened (e.g. using screening instruments), determining whether or not patients would like to receive psycho-oncological care is an important aspect of improving referral practices and, by extension, will allow important progress in the field of psycho oncological care to be made.

AB - [This corrects the article DOI: 10.1371/journal.pone.0202973.]. PMID- 30286173 TI - Microbial enrichment and gene functional categories revealed on the walls of a spent fuel pool of a nuclear power plant. AB - Microorganisms developing in the liner of the spent fuel pool (SFP) and the fuel transfer channel (FTC) of a Nuclear Power Plant (NPP) can form high radiation resistant biofilms and cause corrosion. Due to difficulties and limitations to obtain large samples from SFP and FTC, cotton swabs were used to collect the biofilm from the wall of these installations. Molecular characterization was performed using massively parallel sequencing to obtain a taxonomic and functional gene classification. Also, samples from the drainage system were evaluated because microorganisms may travel over the 12-meter column of the pool water of the Brazilian Nuclear Power Plant (Angra1), which has been functioning since 1985. Regardless of the treatment of the pool water, our data reveal the unexpected presence of Fungi (Basidiomycota and Ascomycota) as the main contaminators of the SFP and FTC. Ustilaginomycetes (Basidiomycota) was the major class contributor (70%) in the SFP and FTC reflecting the little diversity in these sites; nevertheless, Proteobacteria, Actinobacteria, Firmicutes (Bacilli) were present in small proportions. Mapping total reads against six fungal reference genomes indicate that there is, in fact, a high abundance of fungal sequences in samples collected from SFP and FTC. Analysis of the ribosomal internal transcribed spacer (ITS) 1 and 2 regions and the protein found in the mitochondria of eukaryotic cells, cytochrome b (cytb) grouped our sample fungi in the clade 7 as Ustilago and Pseudozyma. In contrast, in the drainage system, Alphaproteobacteria were present in high abundances (55%). The presence of Sphingopyxis, Mesorhizobium, Erythrobacter, Sphingomonas, Novosphingobium, Sphingobium, Chelativorans, Oceanicaulis, Acidovorax, and Cyanobacteria was observed. Based on genomic annotation data, the assessment of the biological function found a higher proportion of protein-coding sequences related to respiration and protein metabolism in SFP and FTC samples. The knowledge of this biological inventory present in the system may contribute to further studies of potential microorganisms that might be useful for bioremediation of nuclear waste. PMID- 30286175 TI - The Daily Mile: What factors are associated with its implementation success? AB - BACKGROUND: Despite the known benefits of a physically active lifestyle, there are few examples of interventions that have been successfully implemented at a population level over a long period of time. One such example is The Daily Mile, a school based physical activity initiative, where a teacher takes their class out daily during class time for a short bout of ambulatory activity. At one school, this activity appears has been sustained over a long period (6 years), has the whole school participating and is now incorporated into its daily routine. The aim of this paper was to understand how The Daily Mile was implemented in primary schools and to assess factors associated with its successful implementation. METHODS: Semi-structured interviews with school staff who had a significant role in implementing The Daily Mile were conducted at four primary schools in central Scotland. Interviews were digitally recorded and transcribed verbatim. Data were analysed using thematic analysis and descriptive analysis and interpretation of data undertaken. Details regarding the school grounds and facilities were also noted during the interviews. RESULTS: Having simple core intervention components, flexible delivery that supports teacher autonomy and being adaptable to suit the specific primary school context appear to be key aspects of The Daily Mile that are related to its implementation success. Other factors relating to how The Daily Mile was developed, trialled and rolled out might also have contributed towards its successful implementation. CONCLUSION: The Daily Mile appears to have several factors which may relate to its implementation success. These are important considerations for others looking to implement The Daily Mile effectively in their primary school or in other contexts. PMID- 30286176 TI - Synthetic viruses-Anything new? PMID- 30286177 TI - Identification of KLF9 and BCL3 as transcription factors that enhance reprogramming of primordial germ cells. AB - Primordial germ cells (PGCs) are precursors of eggs and sperm. Although PGCs are unipotent cells in vivo, they are reprogrammed into pluripotent stem cells (PSCs), also known as embryonic germ cells (EGCs), in the presence of leukemia inhibitory factor and basic fibroblast growth factor (bFGF) in vitro. However, the molecular mechanisms responsible for their reprogramming are not fully understood. Here we show identification of transcription factors that mediate PGC reprogramming. We selected genes encoding transcription factors or epigenetic regulatory factors whose expression was significantly different between PGCs and PSCs with in silico analysis and RT-qPCR. Among the candidate genes, over expression (OE) of Bcl3 or Klf9 significantly enhanced PGC reprogramming. Notably, EGC formation was stimulated by Klf9-OE even without bFGF. G-protein coupled receptor signaling-related pathways, which are involved in PGC reprogramming, were enriched among genes down-regulated by Klf9-OE, and forskolin which activate adenylate cyclase, rescued repressed EGC formation by knock-down of Klf9, suggesting a molecular linkage between KLF9 and such signaling.

PMID- 30286178 TI - Organochlorine pesticides, polybrominated diphenyl ethers and polychlorinated biphenyls in surficial sediments of the Awash River Basin, Ethiopia. AB - This study was initiated to document information on the levels of sediment contamination with organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs). Moreover, it was intended to identify compounds which impose major ecological risks to aquatic organisms. Surficial sediments were collected from 46 locations within the streams and rivers of the Awash River Basin. In total 30 compounds were included in this study: 16 OCPs, 7 PCBs and 7 PBDEs. The total concentrations of OCPs, PCBs, and PBDEs ranged from 6.63 to 206.13 ng g-1- dry weight (dw), 0.85 to 26.56 ng g-1-dw and 3.71 to 18.95 ng g-1-dw respectively. Out of all the tested OCPs, heptachlor, heptachlor epoxide, p,p'-dichlorodiphenyltrichloroethane (p,p'-DDT) and beta hexachlorocyclohexane (beta-HCH) were the most abundant in the study area. The ratio of (beta-HCH/?HCHs) indicated that HCHs were originally from earlier usage of HCH in the area whereas the ratio of (p,p'-DDT/p,p'-DDE) showed that the majority of DDT components were recently introduced into most of the sampling locations. Even though there were relatively low concentrations of PBDEs and PCBs across the sampling sites, substantial amounts of PCBs were observed in Addis Ababa City. According to the established ecological risk indices, p,p'-DDT and gamma-HCH are the major concerns for potential adverse ecological impacts. This study provided the first comprehensive information on organohalogenated compounds' (OCs') occurrences, spatial distributions, and ecological risks in sediments of the Awash River Basin. Thus, the report will be very useful background information for further studies on sediment contamination with OCs' in the region. It also adds important first-hand data to the field of fresh water ecology and provides useful empirical evidence for setting pollution control priorities for an ecologically important, yet largely understudied region. PMID- 30286180 TI - LC3B is not recruited along with the autophagy elongation complex (ATG5-12/16L1) at HCV replication site and is dispensable for viral replication. AB - Hepatitis C virus (HCV) infection is known to induce autophagosome accumulation as observed by the typical punctate cytoplasmic distribution of LC3B-II in infected cells. Previously, we showed that viral RNA-dependent RNA polymerase (NS5B) interacts with ATG5, a major component of the autophagy elongation complex that is involved in the formation of double-membrane vesicles (DMV), and demonstrated that the autophagy elongation complex (ATG5-12/16L1) but not LC3B is required for proper membranous web formation. In this study, the colocalization and in situ interaction of all HCV replicase components with the constituent of the autophagy elongation complex and LC3B were analyzed. The results clearly show the recruitment of the elongation complex to the site of viral replication. Using in situ proximity ligation assay, we show that ATG5, but not ATG16L1, interacts with several HCV replicase components suggesting that the recruitment is directed via the ATG5-12 conjugate. Interestingly, no E3-like conjugation activity of ATG5 12/16L1 can be detected at the at HCV replication site since LC3B-II is not found along with the elongation complex at the site of viral replication. In agreement with this result, no sign of in situ interaction of LC3B with the replicase components is observed. Finally, using dominant negative forms of ATG proteins, we demonstrate that ATG5-12 conjugate, but not LC3-II formation, is critical for viral replication. Altogether, these findings suggest that although HCV needs the elongation complex for its replication, it has developed a mechanism to avoid canonical LC3-II accumulation at viral replication site. PMID- 30286183 TI - Desmoplakin interacts with the coil 1 of different types of intermediate filament proteins and displays high affinity for assembled intermediate filaments. AB - The interaction of intermediate filaments (IFs) with the cell-cell adhesion complexes desmosomes is crucial for cytoskeletal organization and cell resilience in the epidermis and heart. The intracellular desmosomal protein desmoplakin anchors IFs to the cell adhesion complexes predominantly via its four last carboxy-terminal domains (C-terminus). However, it remains unclear why the C terminus of desmoplakin interacts with different IF types or if there are different binding affinities for each type of IFs that may influence the stability of cell-specific adhesion complexes. By yeast three-hybrid and fluorescence binding assays, we found that the coiled-coil 1 of the conserved central rod domain of the heterodimeric cytokeratins (Ks) 5 and 14 (K5/K14) was required for their interaction with the C-terminus of desmoplakin, while their unique amino head- and C-tail domains were dispensable. Similar findings were obtained in vitro with K1/K10, and the type III IF proteins desmin and vimentin. Binding assays testing the C-terminus of desmoplakin with assembled K5/K14 and desmin IFs yielded an apparent affinity in the nM range. Our findings reveal that the same conserved domain of IF proteins binds to the C-terminus of desmoplakin, which may help explain the previously reported broad binding IF-specificity to desmoplakin. Our data suggest that desmoplakin high-affinity binding to diverse IF proteins ensures robust linkages of IF cytoskeleton and desmosomes that maintain the structural integrity of cellular adhesion complexes. In summary, our results give new insights into the molecular basis of the IF-desmosome association. PMID- 30286182 TI - Circular RNA and mRNA profiling reveal competing endogenous RNA networks during avian leukosis virus, subgroup J-induced tumorigenesis in chickens. AB - Avian leukosis virus subgroup J (ALV-J) can induce myeloid tumors and hemangiomas in chickens and causes severe economic losses with commercial layer chickens and meat-type chickens. Here, we generated ribominus RNA sequencing data from three normal chicken spleen tissues and three ALV-J-infected chicken spleen tissues. Structure analysis of transcripts showed that, compared to mRNAs and lncRNAs, chicken circRNAs shared relatively shorter transcripts and similar GC content. Differentially expression analysis showed 152 differentially expressed circRNAs with 106 circRNAs up regulated and 46 circRNAs down regulated. Through comparing differentially expressed circRNA host genes and mRNAs and performed ceRNA network analysis, we found several tumor or immune-related genes, in which, there were four genes existed in both differentially expressed mRNAs and circRNA host genes (Dock4, Fmr1, Zfhx3, Ralb) and two genes (Mll, Aoc3) involved in ceRNA network. We further characterized one exon-intron circRNA derived from HRH4 gene in the ceRNA network, termed circHRH4, which is an abundant and stable circRNA expressed in various tissues and cells in chicken and localizes in cytoplasm. Our results provide new insight into the pathology of ALV-J infection and circRNAs may also mediate tumorigenesis in chicken. PMID- 30286184 TI - Lung tumor segmentation methods: Impact on the uncertainty of radiomics features for non-small cell lung cancer. AB - PURPOSE: To evaluate the uncertainty of radiomics features from contrast-enhanced breath-hold helical CT scans of non-small cell lung cancer for both manual and semi-automatic segmentation due to intra-observer, inter-observer, and inter software reliability. METHODS: Three radiation oncologists manually delineated lung tumors twice from 10 CT scans using two software tools (3D-Slicer and MIM Maestro). Additionally, three observers without formal clinical training were instructed to use two semi-automatic segmentation tools, Lesion Sizing Toolkit (LSTK) and GrowCut, to delineate the same tumor volumes. The accuracy of the semi automatic contours was assessed by comparison with physician manual contours using Dice similarity coefficients and Hausdorff distances. Eighty-three radiomics features were calculated for each delineated tumor contour. Informative features were identified based on their dynamic range and correlation to other features. Feature reliability was then evaluated using intra-class correlation coefficients (ICC). Feature range was used to evaluate the uncertainty of the segmentation methods. RESULTS: From the initial set of 83 features, 40 radiomics features were found to be informative, and these 40 features were used in the subsequent analyses. For both intra-observer and inter-observer reliability, LSTK had higher reliability than GrowCut and the two manual segmentation tools. All observers achieved consistently high ICC values when using LSTK, but the ICC value varied greatly for each observer when using GrowCut and the manual segmentation tools. For inter-software reliability, features were not reproducible across the software tools for either manual or semi-automatic segmentation methods. Additionally, no feature category was found to be more reproducible than another feature category. Feature ranges of LSTK contours were smaller than those of manual contours for all features. CONCLUSION: Radiomics features extracted from LSTK contours were highly reliable across and among observers. With semi-automatic segmentation tools, observers without formal clinical training were comparable to physicians in evaluating tumor segmentation. PMID- 30286181 TI - Conotoxin MVIIA improves cell viability and antioxidant system after spinal cord injury in rats. AB - This study evaluates whether intrathecal MVIIA injection after spinal cord injury (SCI) elicits neuroprotective effects. The test rats were randomly distributed into six groups- sham, placebo, MVIIA 2.5 MUM, MVIIA 5 MUM, MVIIA 10 MUM, and MVIIA 20 MUM-and were administered the treatment four hours after SCI. After the optimal MVIIA dose (MVIIA 10 MUM) was defined, the best time for application, one or four hours, was analyzed. Locomotor hind limb function and side effects were assessed. Forty-eight hours after the injury and immediately after euthanasia, spinal cord segments were removed from the test rats. Cell viability, reactive oxygen species, lipid peroxidation, and glutamate release were investigated. To examine the MVIIA mechanism of action, the gene expressions of pro-apoptotic (Bax, nNOS, and caspase-3, -8, -9, -12) and anti-apoptotic (Bcl-xl) factors in the spinal cord tissue samples were determined by real-time PCR, and the activities of antioxidant enzymes were also investigated. Application of intrathecal MVIIA 10 MUM four hours after SCI prompted a neuroprotective effect: neuronal death decreased (22.46%), oxidative stress diminished, pro-apoptotic factors (Bax, nNOS, and caspase-3, -8) were expressed to a lesser extent, and mitochondrial viability as well as anti-apoptotic factor (Bcl-xl) expression increased. These results suggested that MVIIA provided neuroprotection through antioxidant effects. Indeed, superoxide dismutase (188.41%), and glutathione peroxidase (199.96%), reductase (193.86%), and transferase (175.93%) expressions increased. Therefore, intrathecal MVIIA (MVIIA 10 MUM, 4 h) application has neuroprotective potential, and the possible mechanisms are related to antioxidant agent modulation and to intrinsic and extrinsic apoptotic pathways. PMID- 30286186 TI - Why is the environment important for decision making? Local reservoir model for choice-based learning. AB - Decision making based on behavioral and neural observations of living systems has been extensively studied in brain science, psychology, neuroeconomics, and other disciplines. Decision-making mechanisms have also been experimentally implemented in physical processes, such as single photons and chaotic lasers. The findings of these experiments suggest that there is a certain common basis in describing decision making, regardless of its physical realizations. In this study, we propose a local reservoir model to account for choice-based learning (CBL). CBL describes decision consistency as a phenomenon where making a certain decision increases the possibility of making that same decision again later. This phenomenon has been intensively investigated in neuroscience, psychology, and other related fields. Our proposed model is inspired by the viewpoint that a decision is affected by its local environment, which is referred to as a local reservoir. If the size of the local reservoir is large enough, consecutive decision making will not be affected by previous decisions, thus showing lower degrees of decision consistency in CBL. In contrast, if the size of the local reservoir decreases, a biased distribution occurs within it, which leads to higher degrees of decision consistency in CBL. In this study, an analytical approach for characterizing local reservoirs is presented, as well as several numerical demonstrations. Furthermore, a physical architecture for CBL based on single photons is discussed, and the effects of local reservoirs are numerically demonstrated. Decision consistency in human decision-making tasks and in recruiting empirical data is evaluated based on the local reservoir. This foundation based on a local reservoir offers further insights into the understanding and design of decision making. PMID- 30286188 TI - Inoculating science against potential pandemics and information hazards. AB - The recent de novo assembly of horsepox is an instructive example of an information hazard: published methods enabling poxvirus synthesis led to media coverage spelling out the implications, efficiently disseminating true information that might be used to cause harm. Whether or not the benefits justified the risks, the horsepox saga provides ample reason to upgrade the current system for screening synthesized DNA for hazardous sequences, which does not cover the majority of firms and cannot reliably prevent the assembly of potentially pandemic pathogens. An upgraded system might leverage one-way encryption to confidentially scrutinize virtually all commercial production by a cooperative international network of servers whose integrity can be verified by third parties. Funders could support participating institutions to ease the transition or outright subsidize the market to make clean DNA cheaper, while boycotts by journals, institutions, and funders could ensure compliance and require hardware-level locks on future DNA synthesizers. However, the underlying problem is that security and safety discussions among experts typically follow potentially hazardous events rather than anticipating them. Changing norms and incentives to favor preregistration and advisory peer review of planned experiments could test alternatives to the current closeted research model in select areas of science. Because the fields of synthetic mammalian virology and especially gene drive research involve technologies that could be unilaterally deployed and may self-replicate in the wild, they are compelling candidates for initial trials of early-stage peer review. PMID- 30286185 TI - Features of urinary Escherichia coli isolated from children with complicated and uncomplicated urinary tract infections in Mexico. AB - The Hospital Infantil de Mexico Federico Gomez (HIMFG) is a tertiary care hospital in Mexico City where Escherichia coli is frequently isolated from the urine samples of pediatric patients with urinary tract infections. A collection of 178 urinary Escherichia coli (UEc) isolates associated with complicated and uncomplicated urinary tract infections were evaluated in this study. The patterns of resistance to 9 antibiotic classes showed that 60.7% of the UEc isolates had a highly multidrug-resistant (MDR) profile. Genetic diversity analyses of the UEc isolates showed a high variability and revealed 16 clusters associated with four phylogenetic groups, namely, groups A, B1, B2, and D. Phylogenetic group B2 was widely associated with the 16 clusters as well as with virulence and fitness genes. The virulence and fitness genes in the UEc isolates, which included fimbriae-, siderophore-, toxin-, and mobility-associated genes, were grouped as occurring at a low, variable, or high frequency. Interestingly, only the papF gene could be amplified from some UEc isolates, and the sequence analysis of the pap operon identified an insertion sequence (IS) element and gene loss. These data suggested pathoadaptability and the development of immune system evasion, which was confirmed by the loss of P fimbriae-associated agglutination in the UEc isolates. E. coli clone O25-ST131 had a prevalence of 20.2% among the UEc isolates; these isolates displayed both a highly MDR profile and the presence of the papGII, fimH, papGIII, iutD, sat, hlyA, and motA genes. In conclusion, the UEc isolates from complicated urinary tract infection (cUTI) were characterized as being MDR, highly genetically diverse, and associated with phylogenetic group B2 and many virulence and fitness genes. Additionally, gene loss and IS elements were identified in some UEc isolates identified as clone O25-ST131.

PMID- 30286187 TI - Comparison of the IPSA and HIPO algorithms for interstitial tongue high-dose-rate brachytherapy. AB - PURPOSE: This study aimed to compare the inverse planning simulated annealing (IPSA) stochastic algorithm with the hybrid inverse planning and optimization (HIPO) algorithm for interstitial tongue high-dose-rate (HDR) brachytherapy. METHODS: Twenty patients who received radiotherapy for tongue cancer using interstitial HDR brachytherapy were retrospectively selected for this study. Oncentra Brachy v. 4.3 was used for IPSA and HIPO planning. Four to eight fixed catheter configurations were determined according to the target shape. During the optimization process, predetermined constrain values were used for each IPSA and HIPO plan. The dosimetric parameters and dwell time were analyzed to evaluate the performances of the plans. RESULTS: The total dwell time using IPSA was 4 seconds longer than that of HIPO. The number of active positions per catheter for the IPSA plans were approximately 2.5 fewer than those of the HIPO plans. The dose volumetric parameters related to the clinical target volume with IPSA were lower than those with HIPO. In terms of the dose-volumetric parameters related to normal tissue, HIPO tended to associate with slightly higher values than IPSA, without statistical significance. After GrO, the target coverages were satisfied to clinical goal for all patients. The total dwell times was approximately increased by 10%. CONCLUSIONS: The IPSA and HIPO dose optimization algorithms generate similar dosimetric results. In terms of the dwell time, HIPO appears to be more beneficial.

Experimental evidence reveals that one pathway for clearance of waste, termed intra-mural peri-arterial drainage (IPAD), is the rapid drainage of interstitial fluid along basement membranes (BM) of the smooth muscle cells of cerebral arteries; failure of IPAD is closely associated with the pathology of Alzheimer's disease (AD), but its driving mechanism remains unclear. We have previously shown that arterial pulsations generated by the heart beat are not strong enough to drive IPAD. Here we present computational evidence for a mechanism for clearance of waste from the brain that is driven by functional hyperaemia, that is, the dilatation of cerebral arterioles as a consequence of increased nutrient demand from neurons. This mechanism is based on our model for the flow of fluid through the vascular BM. It accounts for clearance rates observed in mouse experiments, and aligns with pathological observations and recommendations to lower the individual risk of AD, such as mental and physical activity. Thus, our neurovascular hypothesis should act as the new working hypothesis for the driving force behind IPAD. PMID- 30286192 TI - Association between mitral valve prolapse and sudden sensorineural hearing loss: A case-control population-based study. AB - This study aimed to evaluate the relationship between sudden sensorineural hearing loss (SSNHL) and MVP using a population-based dataset. Data for this case control study were retrieved from the Taiwan Longitudinal Health Insurance Database. In total, 3399 cases of newly diagnosed SSNHL were identified. We used propensity score matching to select 3399 comparison patients (one for every case) from the same dataset. The selected matching variables included age, sex, monthly income, geographical location, urbanization level of the patient's residence, hypertension, diabetes, and hyperlipidemia. Chi-squared tests were used to compare differences in sociodemographic characteristics, while conditional logistic regression analyses were used to examine the association of SSNHL with previously diagnosed MVP. Of the 6798 sampled subjects, 131 (1.93%) patients had received a diagnosis of MVP prior to the index date. A significant difference in the prevalence of prior MVP between cases and controls (2.41% vs. 1.44%, p = 0.004) was observed. The conditional logistic regression analysis conditioned on gender, age, monthly income, urbanization level, geographic region, hyperlipidemia, diabetes, and hypertension suggested that the odds ratio of prior MVP for cases was 1.69 (95% confidence interval (CI): 1.18~2.42) compared to controls. Our study found that patients with MVP had a 1.69-fold higher risk of getting SSNHL compared to patients without MVP.

PMID- 30286195 TI - Tropheryma whipplei colonization in HIV-infected individuals is not associated with lung function or inflammation. AB - Studies demonstrate that Tropheryma whipplei (T. whipplei) is present in the lungs of healthy individuals without acute respiratory symptoms or acute respiratory infection and is more common in the lungs of HIV-infected individuals and in smokers. The impact of T. whipplei colonization in the lung on local inflammation and pulmonary dysfunction in HIV-infected individuals is currently unknown. In this study, we performed specific polymerase chain reaction (PCR) and sequencing for T. whipplei in bronchoalveolar lavage (BAL) and induced sputum (IS) samples in 76 HIV-infected participants from three clinical sites. Pulmonary function and proinflammatory cytokine and chemokine levels in BAL were measured. Frequency of T. whipplei in either BAL or IS was 43.4%. The sensitivity and specificity of IS compared to BAL for detection of T. whipplei was 92.3% and 84.2%, respectively, and isolates of T. whipplei in the BAL and IS in the same subject shared genetic identity. Pulmonary function measures were not associated with T. whipplei colonization, and proinflammatory cytokine and chemokine levels in BAL and plasma as well as percentages of inflammatory cells in BAL and IS were not higher in colonized individuals. Overall, these results indicate that T. whipplei colonization in the lung is common, but may not be associated with decreased pulmonary function or inflammation in HIV-infected individuals.

AB - The role of the spleen in the induction of an immune response to orally administered antigens is still under discussion. Although it is well known that after oral antigen administration specific germinal centres are not only formed in the Peyers patches (PP) and the mesenteric lymph nodes (mLN) but also in the spleen, there is still a lack of functional data showing a direct involvement of splenic B cells in an IgA immune response in the gut. In addition, after removal of mLN a high level of IgA+ B cells was observed in the gut. Therefore, in this study we analysed the role of the spleen in the induction of IgA+ B cells in the gut after mice were orally challenged with antigens. Here we have shown that antigen specific splenic IgM+ B cells after in vitro antigen stimulation as well as oral immunisation of donor mice were able to migrate into the gut of recipient mice, where they predominantly switch to IgA+ plasma cells. Furthermore, stimulation of recipient mice by orally administered antigens enhanced the migration of the splenic B cells into the gut as well as their switch to IgA+ plasma cells. Removal of the mLN led to a higher activation level of the splenic B cells. Altogether, our results imply that splenic IgM+ B cells migrate in the intestinal lamina propria, where they differentiate into IgA+ plasma cells and subsequently proliferate. In conclusion, we demonstrated that the spleen plays a major role in the gut immune response serving as a reservoir of immune cells that migrate to the site of antigen entrance. PMID- 30286200 TI - Sport motivation and doping in adolescent athletes. AB - BACKGROUND: Although performance-enhancing drugs appear to be prevalent in adolescent sports, relatively little attention has been paid to why adolescent athletes decide to use these drugs. In this study, we examine doping among adolescents from a motivational perspective and explore how motivational variables, such as achievement goal orientations and the perceived self determination of sports activities, may be related to moral attitudes, doping intentions and doping behavior in adolescents who participate in competitive sports. METHODOLOGY: The study included 1035 adolescents participating in competitive sports from all regions of the Czech Republic (mean age = 16.3 years). The respondents completed a battery of questionnaires assessing their achievement goal orientations (task, ego), sports motivation at various levels of self-determination (intrinsic motivation, external regulation, amotivation), moral attitudes toward sport competition (acceptance of cheating, keeping winning in proportion, attitudes toward doping), doping intentions and doping behavior. A structural equation model was used to test the relations among motivational variables, attitudes, intentions and doping behavior. PRINCIPAL RESULTS: Our analyses indicated a good fit with the proposed model, which explained 59% of the variance in doping intentions and 17.6% of the variance in doping behavior. Within the model, task orientation was positively associated with intrinsic motivation and lower amotivation, whereas ego orientation was positively associated with extrinsic regulation and amotivation. Furthermore, intrinsic motivation was positively associated with keeping winning in proportion and negatively associated with acceptance of cheating and attitudes toward doping; the less self-determined forms of motivation showed opposite relationships. However, only the acceptance of cheating and attitudes toward doping were related to doping intention, which subsequently predicted doping behavior. CONCLUSIONS/SIGNIFICANCE: The results provide further evidence that sports motivation represents a psychological variable that should be considered in anti doping policies, programs, and interventions aimed at the adolescent population because motivation was linked to the doping-related attitudinal variables and also partially mediated the effect of achievement goal orientations in this regard. On the basis of these results, we may argue that the focus on intrinsic enjoyment, self-referenced criteria of success and self-improvement may be related to more negative attitudes toward doping and cheating, lower doping intentions and less frequent doping behavior, whereas the emphasis on competition, comparison with others and external motivation appear to be related to the opposite outcomes. PMID- 30286201 TI - B cell responses to apoptotic cells in MFG-E8-/- mice. AB - Defective clearance of apoptotic cells in MFG-E8 deficient mice results in lupus like disease in the mixed B6x129, but not pure B6 background. The lack of overt autoimmunity in MFG-E8-/- B6 mice suggests that accumulation of apoptotic cells is not sufficient to break central tolerance. However, the delayed clearance of apoptotic cells in the follicles of MFG-E8-/- B6 mice provides an excellent opportunity to investigate how B cells respond to excessive apoptotic cells in the periphery under relatively non-inflammatory conditions. In MFG-E8-/- B6 mice, we found increased IgG2c production against apoptotic cells and oxidized LDL. Apoptotic cell induced antibody responses depended on MyD88 signal and T cell help. In addition, MFG-E8-/- B6 mice had enlarged MZ B cell compartments as well as an enhanced antibody response to NP-Ficoll. Moreover, a significant percentage of MZ B cells in aged MFG-E8-/- B6 mice migrated into follicles. Injecting apoptotic cells or oxidized LDL into wild type mice as well as physiological accumulation of LDL in ApoE-/- mice recapitulated the translocation of MZ B cells. To determine how MFG-E8 deficiency affects the functions of autoreactive B cells specific for nucleic acids in the periphery under non-inflammatory conditions, we utilized BCR transgenic mice to bypass central selection and compared the differentiation of TLR9 dependent anti-dsDNA 56R B cells and TLR7 dependent anti-ssRNA H564 B cells in MFG-E8-/- mice. In MFG-E8-/- 56R mice, anti dsDNA specific 56R/Vkappa38c B cells differentiated into MZ B cells but not AFCs. On the contrary, in MFG-E8-/-H564 mice, anti-ssRNA specific H564 B cells further differentiated into GC B cells and AFCs. Adoptive transfer of activated autoreactive B cells confirmed that H564 B cells were more sensitive to apoptotic cell antigens than 56R B cells. Our observations provide new insights about the MZ B cell translocation in lupus patients as well as the dichotomy of TLR9 and TLR7 signals in the pathogenesis of lupus.

PMID- 30286203 TI - Scavenger receptor-C acts as a receptor for Bacillus thuringiensis vegetative insecticidal protein Vip3Aa and mediates the internalization of Vip3Aa via endocytosis. AB - The vegetative insecticidal proteins (Vip), secreted by many Bacillus thuringiensis strains during their vegetative growth stage, are genetically distinct from known insecticidal crystal proteins (ICPs) and represent the second generation insecticidal toxins. Compared with ICPs, the insecticidal mechanisms of Vip toxins are poorly understood. In particular, there has been no report of a definite receptor of Vip toxins to date. In the present study, we identified the scavenger receptor class C like protein (Sf-SR-C) from the Spodoptera frugiperda (Sf9) cells membrane proteins that bind to the biotin labeled Vip3Aa, via the affinity magnetic bead method coupled with HPLC-MS/MS. We then certified Vip3Aa protoxin could interact with Sf-SR-C in vitro and ex vivo. In addition, downregulation of SR-C expression in Sf9 cells and Spodoptera exigua larvae midgut reduced the toxicity of Vip3Aa to them. Coincidently, heterologous expression of Sf-SR-C in transgenic Drosophila midgut significantly enhanced the virulence of Vip3Aa to the Drosophila larvae. Moreover, the complement control protein domain and MAM domain of Sf-SR-C are involved in the interaction with Vip3Aa protoxin. Furthermore, endocytosis of Vip3Aa mediated by Sf-SR-C correlates with its insecticidal activity. Our results confirmed for the first time that Sf-SR-C acts as a receptor for Vip3Aa protoxin and provides an insight into the mode of action of Vip3Aa that will significantly facilitate the study of its insecticidal mechanism and application. PMID- 30286204 TI - Psychometric properties of the German version of the Leicester Cough Questionnaire in sarcoidosis. AB - BACKGROUND: Cough is one of the most common symptoms in general and pulmonary medicine with profound negative impact on health-related quality of life (HRQL). The Leicester Cough Questionnaire (LCQ) is a validated HRQL questionnaire, yet a validated German version of the LCQ is not available and it has never been tested in a cohort with sarcoidosis. OBJECTIVES: To translate the LCQ into German and determine its psychometric properties. METHODS: The LCQ was translated in a forward-backward approach. Structured interviews in sarcoidosis patients were performed. Subsequently, sarcoidosis patients were asked to answer the German LCQ and comparative questionnaires. Distribution properties, item difficulty, concurrent validity, Rasch model fit and internal consistency of the German LCQ were determined. RESULTS: 200 patients with sarcoidosis were included. We provide evidence for reliability, unidimensionality and internal consistency. However, only a moderate correlation with general and respiratory-specific HRQL questionnaires, no Rasch model fit could be shown. Skewed responses caused by floor effects were detected. CONCLUSION: We demonstrate that the German LCQ is valid and reliable and its psychometric properties fulfil the standards required for its use in clinical settings as well as in interventional trials.

PMID- 30286205 TI - Hepatitis C virus genetic diversity by geographic region within genotype 1-6 subtypes among patients treated with glecaprevir and pibrentasvir. AB - Hepatitis C virus (HCV) is genetically diverse and includes 7 genotypes and 67 confirmed subtypes, and the global distribution of each HCV genotype (GT) varies by geographic region. In this report, we utilized a large dataset of NS3/4A and NS5A sequences isolated from 2348 HCV GT1-6-infected patients treated with the regimen containing glecaprevir/pibrentasvir (GLE/PIB) to assess genetic diversity within HCV subtypes by geographic region using phylogenetic analyses, and evaluated the prevalence of baseline amino acid polymorphisms in NS3 and NS5A by region/country and phylogenetic cluster. Among 2348 NS3/4A and NS5A sequences, phylogenetic analysis identified 6 genotypes and 44 subtypes, including 3 GT1, 8 GT2, 3 GT3, 13 GT4, 1 GT5, and 16 GT6 subtypes. Phylogenetic analysis of HCV subtype 1a confirmed the presence of two clades, which differed by geographic region distribution and NS3 Q80K prevalence. We detected phylogenetic clustering by country in HCV subtypes 1a, 1b, 2a, 2b, and 5a, suggesting that genetically distinct virus lineages are circulating in different countries. In addition, two clades were detected in HCV GT4a and GT6e, and NS5A amino acid polymorphisms were differentially distributed between the 2 clades in each subtype. The prevalence of NS3 and NS5A baseline polymorphisms varied substantially by genotype and subtype; therefore, we also determined the activity of GLE or PIB against replicons containing NS3/4A or NS5A from HCV GT1-6 clinical samples representing 6 genotypes and 21 subtypes overall. GLE and PIB retained activity against the majority of HCV replicons containing NS3/4A or NS5A from HCV GT1-6 clinical samples, with a median EC50 of 0.29 nM for GLE and 1.1 pM for PIB in a transient replicon assay. The data presented in this report expands the available data on HCV epidemiology, subtype diversity by geographic region, and NS3 and NS5A baseline polymorphism prevalence. PMID- 30286207 TI - A rare case of visceral leishmaniasis in an immunocompetent traveler returning to the United States from Europe. AB - A young, healthy traveler returning to the United States presented with fever, night sweats, splenomegaly, and pancytopenia. Bone marrow biopsy revealed leishmaniasis (Leishmania infantum), likely acquired in southern France. Although many cases of endemic visceral leishmaniasis (VL) have been reported in Europe, this is a rare case of imported VL in a healthy traveler returning from Europe to the US. Despite successful initial treatment with liposomal amphotericin B (LamB), relapse occurred. Treatments for VL in immunocompetent individuals are highly effective, but relapse can occur. There is more extensive experience in endemic areas with treating relapse that may be lacking in North America. This case alerts physicians in the US that immunocompetent adults can acquire VL during brief visits to endemic areas in Europe. It is important that travelers be counseled on preventive measures. Patients should be monitored after treatment for relapse. PMID- 30286208 TI - Can we predict when to start renal replacement therapy in patients with chronic kidney disease using 6 months of clinical data? AB - PURPOSE: We aimed to develop a model of chronic kidney disease (CKD) progression for predicting the probability and time to progression from various CKD stages to renal replacement therapy (RRT), using 6 months of clinical data variables routinely measured at healthcare centers. METHODS: Data were derived from the electronic medical records of Ajou University Hospital, Suwon, South Korea from October 1997 to September 2012. We included patients who were diagnosed with CKD (estimated glomerular filtration rate [eGFR] < 60 mL.min-1.1.73 m-2 for >= 3 months) and followed up for at least 6 months. The study population was randomly divided into training and test sets. RESULTS: We identified 4,509 patients who met reasonable diagnostic criteria. Patients were randomly divided into 2 groups, and after excluding patients with missing data, the training and test sets included 1,625 and 1,618 patients, respectively. The integral mean was the most powerful explanatory (R2 = 0.404) variable among the 8 modified values. Ten variables (age, sex, diabetes mellitus[DM], polycystic kidney disease[PKD], serum albumin, serum hemoglobin, serum phosphorus, serum potassium, eGFR (calculated by Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI]), and urinary protein) were included in the final risk prediction model for CKD stage 3 (R2 = 0.330). Ten variables (age, sex, DM, GN, PKD, serum hemoglobin, serum blood urea nitrogen[BUN], serum calcium, eGFR(calculated by Modification of Diet in Renal Disease[MDRD]), and urinary protein) were included in the final risk prediction model for CKD stage 4 (R2 = 0.386). Four variables (serum hemoglobin, serum BUN, eGFR(calculated by MDRD) and urinary protein) were included in the final risk prediction model for CKD stage 5 (R2 = 0.321). CONCLUSION: We created a prediction model according to CKD stages by using integral means. Based on the results of the Brier score (BS) and Harrel's C statistics, we consider that our model has significant explanatory power to predict the probability and interval time to the initiation of RRT. PMID- 30286209 TI - Serology, virulence and molecular characteristics of Vibrio parahaemolyticus isolated from seafood in Zhejiang province. AB - Vibrio parahaemolyticus is a leading foodborne pathogen in southeastern China. In this study, 105 strains of V. parahaemolyticus were isolated from fresh seafood in 2013 and 2014. The serotypes, virulence-associated genes and sequence types (STs) of these strains were analyzed. 26 defined serotypes were identified and 69 strains (65.7%) had untypeable O or K antigen. 8 strains (7.6%) had the virulence associated gene tdh and no strain carried the trh gene. 45.7% (48/105) of isolates contained all four T3SS1 genes and 50% (4/8) tdh+ trh- V. parahaemolyticus isolates lacked at least one of the four tested T3SS2alpha genes. 105 strains could be categorized into 84 STs and only 3 STs (ST3, ST8, ST675) had appeared in clinical strains. V. parahaemolyticus strains from seafood have more diverse and untypeable serotypes, less virulence-associated genes and more STs than strains from clinical sources. PMID- 30286210 TI - Epigallocatechin-3 gallate prevents pressure overload-induced heart failure by up regulating SERCA2a via histone acetylation modification in mice. AB - Heart failure is a common, costly, and potentially fatal condition. The cardiac sarcoplasmic reticulum Ca-ATPase (SERCA2a) plays a critical role in the regulation of cardiac function. Previously, low SERCA2a expression was revealed in mice with heart failure. Epigallocatechin-3-gallate (EGCG) can function as an epigenetic regulator and has been reported to enhance cardiac function. However, the underlying epigenetic regulatory mechanism is still unclear. In this study, we investigated whether EGCG can up-regulate SERCA2a via histone acetylation and play role in preventing heart failure. For this, we generated a mouse model of heart failure by performing a minimally invasive transverse aortic constriction (TAC) operation and used this to test the effects of EGCG. The TAC+EGCG group showed nearly normal cardiac function compared to that in the SHAM group. The expression of SERCA2a was decreased at both the mRNA and protein levels in the TAC group but was enhanced in the TAC+EGCG group. Levels of AcH3 and AcH3K9 were determined to decrease near the promoter region of Atp2a2 (the gene encoding SERCA-2a) in the TAC group, but were elevated in the TAC+EGCG group. Meanwhile, HDAC1 activity and binding near the Atp2a2 promoter were increased in the TAC group but decreased with EGCG addition. Further, binding levels of GATA4 and Mef2c near the Atp2a2 promoter region were reduced in TAC hearts, which might have been caused by histone hypoacetylation; this was reversed by EGCG. Together, upregulation of SERCA2a via the modification of histone acetylation plays a role in EGCG-mediated prevention of pressure overload-induced heart failure, and this might represent a novel pharmacological target for the treatment of heart failure. PMID- 30175239 TI - Mainstreaming as rhetoric or reality? Gender and global health at the World Bank. AB - Background: Over the past decade gender mainstreaming has gained visibility at global health organisations. The World Bank, one of the largest funders of global health activities, released two World Development Reports showcasing its gender policies, and recently announced a $1 billion initiative for women's entrepreneurship. We summarise the development of the Bank's gender policies and analyse its financing of gender projects in the health sector. This article is intended to provide background for future research on the Bank's gender and global health portfolio. Methods: First, we constructed a timeline of the Bank's gender policy development, through a review of published articles, grey literature, and Bank documents and reports. Second, we performed a health-focused analysis of publicly available Bank gender project databases, to track its financing of health sector projects with a gender 'theme' from 1985-2017. Results: The Bank's gender policy developed through four major phases from 1972 2017: 'women in development' (WID), institutionalisation of WID, gender mainstreaming, and gender equality through 'smart economics'. In the more inclusive Bank project database, projects with a gender theme comprised between 1.3% (1985-1989) and 6.2% (2010-2016) of all Bank commitments. Most funding targeted middle-income countries and particular health themes, including communicable diseases and health systems. Major gender-related trust funds were absent from both databases. The Bank reports that 98% of its lending is 'gender informed', which indicates that the gender theme used in its publicly available project databases is poorly aligned with its criteria for gender informed projects. Conclusion: The Bank focused most of its health sector gender projects on women's and girls' issues. It is increasingly embracing private sector financing of its gender activities, which may impact its poverty alleviation agenda. Measuring the success of gender mainstreaming in global health will require the Bank to release more information about its gender indicators and projects.

AB - Natural killer (NK) cells provide the first line of defense against malaria parasite infection. However, the molecular mechanisms through which NK cells are activated by parasites are largely unknown, so is the molecular basis underlying the variation in NK cell responses to malaria infection in the human population. Here, we compared transcriptional profiles of responding and non-responding NK cells following exposure to Plasmodium-infected red blood cells (iRBCs) and identified MDA5, a RIG-I-like receptor involved in sensing cytosolic RNAs, to be differentially expressed. Knockout of MDA5 in responding human NK cells by CRISPR/cas9 abolished NK cell activation, IFN-gamma secretion, lysis of iRBCs. Similarly, inhibition of TBK1/IKKepsilon, an effector molecule downstream of MDA5, also inhibited activation of responding NK cells. Conversely, activation of MDA5 by liposome-packaged poly I:C restored non-responding NK cells to lyse iRBCs. We further show that microvesicles containing large parasite RNAs from iRBCs activated NK cells by fusing with NK cells. These findings suggest that NK cells are activated through the MDA5 pathway by parasite RNAs that are delivered to the cytoplasm of NK cells by microvesicles from iRBCs. The difference in MDA5 expression between responding and non-responding NK cells following exposure to iRBCs likely contributes to the variation in NK cell responses to malaria infection in the human population.

PMID- 30286219 TI - Association of Disorganization of Retinal Inner Layers With Visual Acuity Response to Anti-Vascular Endothelial Growth Factor Therapy for Macular Edema Secondary to Retinal Vein Occlusion. AB - Importance: Disorganization of retinal inner layers (DRIL) has demonstrated significant correlations with visual acuity (VA) in center-involved diabetic macular edema. In patients with retinal vein occlusion (RVO) and secondary macular edema, DRIL may be a useful biomarker in determining VA outcomes. Objective: To examine whether DRIL at baseline and after treatment is associated with VA in RVO. Design, Setting, and Participants: A retrospective review of records of 147 patients 18 years or older with treatment-naive branch RVO (BRVO), central RVO (CRVO), or hemispheric RVO (HRVO), with a minimum of 12 months of follow-up, who presented to a tertiary ophthalmic center from December 1, 2010, to January 1, 2016, was conducted. Data collection continued through January 2017. Exclusion criteria included active confounding retinal or ocular disease, history of pars plana vitrectomy, or prior intravitreal injections. Two masked graders calculated a DRIL score based on DRIL presence in 3 predefined regions on spectral-domain optical coherence tomography at baseline, 6 months, and 12 months. A third masked grader was used for discrepancies. Exposures: Anti vascular endothelial growth factor (AVF) therapy (ranibizumab, aflibercept, or bevacizumab) determined by the treating physician. Main Outcomes and Measures: The DRIL score at baseline for determining VA outcomes and correlation of VA with changes in DRIL burden in response to AVF therapy. Results: In the 147 patients (mean [SD] age, 68.9 [13.1] years; 75 [51.0%] female), baseline DRIL was seen in 91 eyes (61.9%). In the BRVO group but not the CRVO group, baseline DRIL was associated with lower baseline Early Treatment Diabetic Retinopathy Study (ETDRS) score (score of 66.7 for no DRIL vs 54.6 for DRIL, P = .002). Absence of DRIL at baseline in the CRVO/HRVO group correlated with greater VA gains at 6 months, adjusting for baseline VA (score change of 19.50 for no DRIL vs 12.72 for DRIL; P = .04). During 12 months, continued DRIL presence in BRVO was associated with less VA gain up to 6 months (score change of 6.2 for the DRIL increase group vs 18.6 for the DRIL decrease group vs 2.9 for the DRIL stable group; P = .02). Increasing DRIL scores in CRVO/HRVO were associated with reduced VA improvement at 6 months (score change of -0.12 for the DRIL increase group vs 16.90 for the DRIL decrease group vs 8.45 for the DRIL stable group; P = .002) and 12 months (score change of -1.91 for the DRIL increase group vs 17.83 for the DRIL decrease group vs 6.97 for the DRIL stable group; P < .001). Conclusions and Relevance: Baseline DRIL presence and DRIL burden changes with AVF therapy for macular edema secondary to RVO may be useful biomarkers of ETDRS score improvements.

PMID- 30286222 TI - Sense of Effort and Fatigue Associated With Talking After Total Laryngectomy. AB - Purpose: Sense of effort and fatigue associated with talking was compared in individuals with and without a total laryngectomy. Method: An online survey of individuals using tracheoesophageal speech (TES; n = 222), electrolaryngeal speech (ELS; n = 132), esophageal speech (n = 41), and laryngeal speech (LS; n = 112) asked about 3 domains of effort when talking: frequency of occurrence, withdrawal from talking, and location in the body. Three aspects of fatigue were explored: frequency of occurrence, fatigue type, and duration of talking before fatigue. Results: Alaryngeal groups reported significantly more talking-related effort and fatigue than the LS group. Sixty-three percent of all respondents indicated that effort caused them to talk less, with no group differences on this item. Significantly more effort was localized to the lips and tongue by ELS compared with TES and LS groups. Both the ELS and TES groups had higher shoulder/arm effort when talking compared with the esophageal speech and LS groups. ELS respondents reported less fatigue than the TES group. When fatigue was present, the TES group had more physical and less mental fatigue than the ELS group. The duration of talking before experiencing fatigue was significantly shorter for the alaryngeal groups compared with the LS group. Conclusions: Effort and fatigue associated with talking are a common report for individuals using alaryngeal speech. The location of effort within the body and the type of fatigue experienced vary to some extent across alaryngeal speaking methods.

All inpatients with relevant diagnoses were included. Linear regression was used to estimate changes in incidence. Logistic regression was used to compare demographics and outcomes between primary and secondary diagnoses, including age, sex, race, income, primary payer, region, year of admission, length of stay, cost, and disposition at discharge. Exposures: Eye trauma. Main Outcomes and Measures: Incidence and characteristics of inpatient primary and secondary eye trauma. Results: From 2001 to 2014, there were an estimated 939 608 inpatient admissions (of whom 556 886 were male patients [59.3%]; overall mean [SD] age, 49.4 [25.2] years) in the United States because of eye trauma diagnoses, with 778 967 of these (82.9%) as a secondary diagnosis. The incidence of primary eye trauma decreased from 3.9 to 3.0 per 100 000 population (difference, 0.9 [95% CI, 0.2-1.6] per 100 000 population; P = .001). The incidence of eye trauma as a secondary admitting diagnosis increased from 14.5 to 19.0 per 100 000 population (difference, 4.5 [95% CI, 1.9-7.2] per 100 000 population; P = .004). This was largely attributed to an increasing number of falls in individuals older than 65 years. The most frequent diagnosis was orbital fracture (64 149 [39.9%]) for primary trauma and contusion of eye and adnexa (19 301 [37.8%]) for secondary trauma. Primary trauma was more common in children (adjusted odds ratio [aOR], 2.21 [95% CI, 2.09-2.32]) and adolescents (aOR, 1.25 [95% CI, 1.19-1.32]) than adults (reference), African American individuals (aOR, 1.89 [95% CI, 1.81-1.97]) and Hispanic individuals (aOR, 1.52 [95% CI, 1.45-1.59]) than white individuals, and uninsured patients (aOR, 1.14 [95% CI, 1.07-1.22]) and those receiving Medicaid (aOR, 1.12 [95% CI, 1.05-1.19]) than Medicare beneficiaries. Patients with a primary diagnosis were more likely to have a stay of less than 3 days (patients with a primary diagnosis: 101 796 [63.4%]; secondary diagnosis: 274 538 [35.2%]), more likely to have costs in the lowest quartile (patients with a primary diagnosis: 51 212 [31.9%]; secondary diagnosis: 166 260 [21.3%]), and less likely to die (patients with a primary diagnosis: 526 [0.3%]; secondary diagnosis: 20 929 [2.7%]). Conclusions and Relevance: These findings suggest that the increasing number of falls in individuals older than 65 years and the high risk of primary eye trauma in populations such as children and adolescents warrant the development and implementation of effective preventive strategies. Many of these patients are seen in ophthalmology practices where proactive risk assessment and counseling can play a critical role.

AB - Importance: Patients with head and neck cancer (HNC) experience increased risk of depression and compromised quality of life. Identifying patients with HNC at risk of depression can help establish targeted interventions. Objective: To identify factors that may be associated with the development of moderate or severe depression during treatment of HNC. Design, Setting, and Participants: This is a retrospective, ad hoc, secondary analysis of prospectively collected data from a randomized, double-blind, placebo-controlled clinical trial. Patients were screened at academic- and community-based tertiary care HNC centers from January 2008 to December 2011. Of the 125 evaluable patients with stages II through IV HNC but without baseline depression, 60 were randomized to prophylactic antidepressant escitalopram oxalate and 65 to placebo at the time of the initial diagnosis. Data analyses were conducted from May 2016 to April 2017. Main Outcomes and Measures: Depression outcomes were measured using Quick Inventory of Depressive Symptomatology-Self Report (QIDS-SR) scores (range, 0-27 with a score of 11 or higher indicative of moderate or greater depression). Factors that may be associated with development of moderate or severe depression were assessed, including patient demographics; cancer site and stage; primary treatment modality (surgery or radiotherapy); history of depression or other psychiatric diagnosis; previous treatment of depression or suicide attempt, family history of depression, suicide, or suicide attempt; and baseline score on the QIDS-SR and clinician-rated QIDS instruments. Participants were stratified by study site, sex, cancer stage (early [stage II] vs advanced [stage III or IV]), primary modality of treatment (radiotherapy with or without chemotherapy vs surgery with or without radiotherapy), and randomization to placebo or escitalopram and balanced within these strata. Results: The mean (SD) age of the 148 patients in the study population was 63.0 (11.9) years; 118 (79.7%) were men, and 143 (96.6%) were white. In the evaluable population of 125 patients, receiver operating characteristic analyses assessing the area under the curve for baseline QIDS-SR score (0.816; 95% CI, 0.696-0.935) and for initial radiotherapy-based treatment (0.681, 95% CI, 0.552-0.811) suggested that these 2 variables were associated with the likelihood of developing moderate or greater depression during the study period among patients who did not receive prophylactic antidepressants. The diagnostic sensitivity for identifying patients at risk of depression using the baseline QIDS-SR score improved to 100% at a threshold of 2 from 94% at a threshold of 4. Conclusions and Relevance: Baseline symptoms and initial radiotherapy-based treatment may be associated with development of moderate or greater depression in patients with HNC. Patients with QIDS-SR baseline scores of 2 or higher may benefit the most from pharmacologic prophylaxis of depression. PMID- 30286232 TI - Characteristics of Speech Rate in Children With Cerebral Palsy: A Longitudinal Study. AB - Purpose: The purpose of this longitudinal study was to examine the effect of time and sentence length on speech rate and its characteristics, articulation rate and pauses, within 2 groups of children with cerebral palsy (CP). Method: Thirty-four children with CP, 18 with no speech motor involvement and 16 with speech motor involvement, produced sentences of varying lengths at 3 time points that were 1 year apart (mean age = 56 months at first time point). Dependent measures included speech rate, articulation rate, proportion of time spent pausing, and average number and duration of pauses. Results: There were no significant effects of time. For children with no speech motor involvement, speech rate increased with longer sentences due to increased articulation rate. For children with speech motor involvement, speech rate did not change with sentence length due to significant increases in the proportion of time spent pausing and average number of pauses in longer sentences. Conclusions: There were no significant age-related differences in speech rate in children with CP regardless of group membership. Sentence length differentially impacted speech rate and its characteristics in both groups of children with CP. This may be due to cognitive-linguistic and/or speech motor control factors.

PMID- 30286234 TI - Analysis of Cervical Angle in the Submental Muscular Medialization and Suspension Procedure. AB - Importance: The submental muscular medialization and suspension (SMMS) procedure is an option for addressing an obtuse cervical angle in select patients vs the use of traditional rhytidectomy techniques. Objective: To compare the change in position of the cervical point between groups undergoing SMMS vs the traditional rhytidectomy technique. Design, Setting, and Participants: A retrospective review was performed of 141 patients undergoing rhytidectomy in an accredited private surgery center between January 1, 2013, and December 31, 2014, comparing cervical point depth between patients undergoing SMMS vs those undergoing traditional rhytidectomy with platysma plication. Statistical analysis was performed from November 11, 2017, to January 5, 2018. Interventions: Patients underwent either SMMS or traditional rhytidectomy with platysma plication. Main Outcomes and Measures: The primary end point was change in the cervical point distance between preoperative and postoperative standardized profile photos. Results: A total of 141 patients were included in the analysis. A cohort of 46 patients (43 women and 3 men; mean age, 63.5 years [range, 49.0-79.0 years]) underwent neck contouring with the SMMS technique and a cohort of 95 patients (90 women and 5 men; mean age, 61.0 years [range, 48.0-73.0 years]) underwent traditional rhytidectomy with platysmaplasty. The cervical point distance of the SMMS cohort had a mean (SD) postoperative increase of 2.0 (1.05) cm (95% CI, 1.73-2.28; P < .001) compared with 0.78 (0.82) cm in the traditional rhytidectomy cohort (95% CI, 0.54-1.02; P < .001). Conclusions and Relevance: The results of this study suggest that submental muscular medialization and suspension appears to be an effective option to address the obtuse neck in select patients.

AB - Importance: Prospective data on the risk of hepatocellular carcinoma (HCC) according to dose and duration of aspirin therapy are limited. Objective: To examine the potential benefits of aspirin use for primary HCC prevention at a range of doses and durations of use within 2 prospective, nationwide populations. Design, Setting, and Participants: Pooled analysis of 2 prospective US cohort studies: the Nurses' Health Study and the Health Professionals Follow-up Study. Data were accessed from November 1, 2017, through March 7, 2018. A total of 133 371 health care professionals who reported data on aspirin use, frequency, dosage, and duration of use biennially since 1980 in women and 1986 in men were included. Individuals with a cancer diagnosis at baseline (except nonmelanoma skin cancer) were excluded. Main Outcomes and Measures: Cox proportional hazards regression models were used to calculate multivariable adjusted hazard ratios (HRs) and 95% CIs for HCC. Results: Of the 133 371 participants, 87 507 were women and 45 864 were men; in 1996, the median time of follow-up, the mean (SD) age was 62 (8) years for women and 64 (8) years for men. Over more than 26 years of follow-up encompassing 4 232 188 person-years, 108 incident HCC cases (65 women, 43 men) were documented. Compared with nonregular use, regular aspirin use (>=2 standard-dose [325-mg] tablets per week) was associated with reduced HCC risk (adjusted HR, 0.51; 95% CI, 0.34-0.77). This benefit appeared to be dose related: compared with nonuse, the multivariable-adjusted HR for HCC was 0.87 (95% CI, 0.51-1.48) for up to 1.5 standard-dose tablets per week, 0.51 (95% CI, 0.30-0.86) for more than 1.5 to 5 tablets per week, and 0.49 (95% CI, 0.28-0.96) for more than 5 tablets per week (P for trend = .006). Significantly lower HCC risk was observed with increasing duration (P for trend = .03); this decrease was apparent with use of 1.5 or more standard-dose aspirin tablets per week for 5 or more years (adjusted HR, 0.41; 95% CI, 0.21-0.77). In contrast, use of nonaspirin nonsteroidal anti-inflammatory drugs was not significantly associated with HCC risk (adjusted HR, 1.09; 95% CI, 0.78-1.51). Conclusions and Relevance: This study suggests that regular, long-term aspirin use is associated with a dose dependent reduction in HCC risk, which is apparent after 5 or more years of use. Similar associations were not found with nonaspirin NSAIDs. Further research appears to be needed to clarify whether aspirin use represents a feasible strategy for primary prevention against HCC.

PMID- 30286238 TI - Effectiveness of Guided Internet-Based Cognitive Behavioral Therapy vs Face-to Face Clinical Care for Treatment of Tinnitus: A Randomized Clinical Trial. AB - Importance: Accessible clinical care is not always available to individuals with distressing tinnitus. Internet-based cognitive behavioral therapy has the potential to increase access to evidence-based services that manage tinnitus. Research comparing the effectiveness of this internet-based intervention with face-to-face care is required. Objective: To evaluate whether an internet-based cognitive behavioral therapy intervention is at least as effective as established individualized face-to-face clinical care in reducing tinnitus distress and tinnitus-related difficulties. Design, Setting, and Participants: A randomized, multicenter, 2-arm parallel group, noninferiority trial with 2-month follow-up was performed between October 4, 2016, and July 14, 2017. Invited to participate were 374 adults based in the United Kingdom who had been referred to their local tinnitus clinics because of bothersome tinnitus. The experimental group received the internet-based intervention online, and the active control group underwent the usual face-to-face tinnitus care at 1 of 3 UK-based National Health Service hospitals. Participants were randomly assigned (1:1) to either intervention using variable permuted block sizes of 4 and 6. Of 92 participants who were randomized (46 each in the experimental and control groups), 88 participants completed the assessment immediately after intervention and 74 participants completed the follow-up assessment. Interventions: Participants were randomized to receive either 8 weeks of guided internet-based cognitive behavioral therapy or a mean of 2 to 3 individualized face-to-face appointments in a tinnitus clinic. Main Outcomes and Measures: The primary outcome was a change in tinnitus distress (assessed by the Tinnitus Functional Index). Secondary assessment measures were included for insomnia, anxiety, depression, hearing disability, hyperacusis, cognitive failures, and satisfaction with life. Results: Of 92 patients overall, 55 (60%) were men with a mean (SD) age of 52.96 (12.07) years and mean (SD) tinnitus duration of 6.54 (9.25) years. The between-group difference in the Tinnitus Functional Index scores after intervention were 5.18 (95% CI, -4.17 to 14.53) at the initial assessment and 5.52 (95% CI, -4.60 to 15.61) at follow-up; both differences were within the noninferiority margin of 13 points for the lower 95% CI. For the secondary outcomes, only outcomes for insomnia fell outside the noninferiority margin, both after intervention and at follow-up, favoring internet-based cognitive behavioral therapy. Conclusions and Relevance: This is the first trial, to our knowledge, to compare an internet-based intervention with standard individualized face-to-face care for tinnitus. It revealed that both interventions are equally effective for reducing tinnitus distress and most tinnitus-related difficulties. Trial Registration: ClinicalTrials.gov identifier: NCT02665975.

AB - Importance: Ovarian cancer is a highly fatal malignant neoplasm with few modifiable risk factors. Case-control studies have reported a modest reduced risk of ovarian cancer among women who frequently use aspirin or regularly use low dose aspirin. Objective: To evaluate whether regular aspirin or nonaspirin nonsteroidal anti-inflammatory drug (NSAID) use and patterns of use are associated with lower ovarian cancer risk. Design, Setting, and Participants: This cohort study analyzed NSAID use and ovarian cancer diagnosis data from 2 prospective cohorts, 93 664 women in the Nurses' Health Study (NHS), who were followed up from 1980 to 2014, and 111 834 in the Nurses' Health Study II (NHSII), who were followed up from 1989 to 2015. Follow-up was completed on June 30, 2014, for the NHS and June 30, 2015, for NHSII. Data were analyzed from June 13, 2016, to September 18, 2017. Exposures: For each analgesic type (aspirin, low dose aspirin, nonaspirin NSAIDs, and acetaminophen), timing, duration, frequency, and number of tablets used were evaluated; exposure information was updated every 2 to 4 years. Main Outcomes and Measures: Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% CIs for associations of aspirin, nonaspirin NSAIDs, and acetaminophen with risk of epithelial ovarian cancer. All statistical tests were 2-sided, with a significance level of .05. Results: In the NHS, the mean (SD) age at baseline (1980) was 45.9 (7.2) years, and 93% of participants identified as non-Hispanic white. In the NHSII, the mean age at baseline (1989) was 34.2 (4.7) years, and 92% identified as non-Hispanic white. Among the 205 498 women in both cohorts, there were 1054 cases of incident epithelial ovarian cancer. Significant associations between aspirin and ovarian cancer risk were not observed when current vs nonuse of any aspirin was evaluated regardless of dose (HR, 0.99; 95% CI, 0.83-1.19). However, when low-dose (<=100 mg) and standard-dose (325-mg) aspirin were evaluated separately, an inverse association for low-dose aspirin (HR, 0.77; 95% CI, 0.61-0.96), but no association for standard-dose aspirin (HR, 1.17; 95% CI, 0.92-1.49) was observed. Current use of nonaspirin NSAIDs was positively associated with risk of ovarian cancer compared with nonuse (HR, 1.19; 95% CI, 1.00-1.41), and significant positive trends for duration of use (P = .02 for trend) and cumulative average tablets per week (P = .03 for trend) were observed. There were no clear associations for the use of acetaminophen. Conclusions and Relevance: These results appear to be consistent with case-control studies that show a reduced risk of ovarian cancer among regular users of low-dose aspirin. An increased risk of ovarian cancer with long-term high-quantity use of other analgesics, particularly nonaspirin NSAIDs, was observed, although this finding requires confirmation.

PMID- 30286242 TI - Pilot Study of Audiometric Patterns in Fuchs Corneal Dystrophy. AB - Purpose: Although Fuchs corneal dystrophy (FCD) is considered an eye disease, a small number of studies have identified genes related to both FCD and hearing loss. Whether FCD is related to hearing loss is unknown. Method: This is a case control study comparing pure-tone audiometry hearing thresholds in 180 patients with FCD from a hospital-based ophthalmology clinic with 2,575 population-based controls from a nationally representative survey, the National Health and Nutrition Examination Survey (from cycles 2005-06 and 2009-10). Generalized estimating equations were used to compare mean better-hearing ear thresholds in the 2 groups adjusted for age, sex, race, and noise exposure. Results: Patients with FCD had higher hearing thresholds (worse hearing) in lower frequencies (mean difference at 0.5 kHz = 3.49 dB HL) and lower hearing thresholds (better hearing) in higher frequencies (difference at 4 kHz = -4.25 dB HL) compared with population-based controls. Conclusion: In the first study to use objectively measured hearing, FCD was associated with poorer low-frequency and better high frequency audiometric thresholds than population controls. Further studies are needed to characterize this relationship. PMID- 30286244 TI - Associations Between Manual Dexterity and Language Ability in School-Age Children. AB - Purpose: We aimed to determine whether individual differences in manual dexterity are associated with specific language skills (nonword repetition, receptive vocabulary, and receptive grammar) after controlling for nonverbal abilities (visual-spatial working memory and intelligence). Method: We assessed manual dexterity using the pegboard task and examined relationships with verbal and nonverbal abilities in a diverse community sample of children (N = 63, mean age = 8;2 [year;months], range: 6;0-10;8) varying in language ability (Comprehensive Evaluation of Language Fundamentals-Fourth Edition core language score M = 105, range: 62-126; Semel, Wiig, & Secord, 2003). Results: Correlational analyses indicated significant relationships between manual dexterity and performance on tests of nonword repetition, receptive vocabulary, receptive grammar, and nonverbal intelligence, after controlling for multiple comparisons. In regression analyses, manual dexterity remained a significant predictor of nonword repetition after controlling for nonverbal abilities and age. In contrast, manual dexterity was no longer significant in predicting receptive vocabulary or grammar when nonverbal intelligence was included as a factor in the model. Conclusions: These findings build on prior work implicating poor fine motor control in child language disorders by identifying a robust relationship between manual dexterity and nonword repetition. Relationships between manual dexterity and receptive language abilities appear to be indirect and mediated by nonword repetition. For clinicians, the results underscore the importance of screening children with poor fine motor control for concomitant language impairments. PMID- 30286245 TI - Service Provision for Children Who Are Hard of Hearing at Preschool and Elementary School Ages. AB - Purpose: To characterize preschool and school services for children who are hard of hearing (CHH), we described service setting, amount, and configuration and analyzed the relationship between service receipt and student hearing levels and language scores. Characteristics of professionals providing services were described and then used to predict level of comfort with skills supporting listening and spoken language. The amount of provider communication with children's audiologists was also investigated. Method: Participants included parents of CHH (preschool n = 174; school n = 155) and professionals (preschool n = 133; school n = 104) who completed interviews and questionnaires as part of a longitudinal study. Children's hearing, speech, and language data were collected from annual testing and analyzed in relation to service data. Results: A majority (81%) of preschool-age CHH received services. Children were more likely to be in a preschool for children who are deaf or hard of hearing (CDHH) or exceptional children than a general education preschool. By elementary school, 70% received services, nearly all in general education settings. Sessions averaged twice a week for a total of approximately 90 min. Children who no longer received services performed significantly better on speech/language measures than those who received services, regardless of service setting. Professionals were primarily speech-language pathologists (SLPs) and teachers of CDHH. SLPs reported significantly less comfort with skills involving auditory development and hearing technologies and less frequent communication with the child's audiologists than teachers of CDHH. Overall communication with audiologists was more frequent in the preschool years. Conclusions: As preschool-age CHH transition into school, the majority continue to qualify for services. Congruent with national trends, school-age CHH in the Outcomes of Children with Hearing Loss study were most often in general education settings. Without specialized preprofessional or postgraduate training, SLPs and teachers of CDHH did not report comfort with all the skills critical to developing listening and spoken language. This finding supports the need for increased implementation of interprofessional practice among SLPs and teachers of CDHH, as well as audiologists, to best meet the needs unique to this population. PMID- 30286246 TI - Explaining Reading Comprehension in Children With Developmental Language Disorder: The Importance of Elaborative Inferencing. AB - Purpose: Reading comprehension is a key indicator of academic and psychosocial outcomes. Children with developmental language disorder (DLD) tend to find reading comprehension challenging. This study aimed to explore the literal and inferential (cohesive, elaborative, and lexical) comprehension of children with DLD, their typically developing (TD) peers, and, uniquely, a group of children with low language (LL) proficiency. Method: Children aged 10-11 years with either typical development (n = 16), LL proficiency (n = 14), or DLD (n = 14) were recruited from 8 primary schools. They completed a battery of standardized language and literacy assessments. Responses to literal and inferential questions on the Wechsler Individual Achievement Test-Second UK Edition (Wechsler, 2005) were analyzed. Results: A disproportionate difficulty in answering inferential relative to literal questions was found for the DLD group compared to the LL and TD groups. Children with DLD were significantly poorer at elaborative inferencing than both their peers with LL proficiency and TD peers, but there were no group differences in cohesive or lexical inferencing. There was a significant positive association between inferencing ability and vocabulary knowledge, single word reading accuracy, grammatical skill, and verbal working memory. The importance of single word reading accuracy was especially evident as a partial mediator of the relationship between vocabulary knowledge and inferencing ability. Conclusions: These results indicate that interventions targeting the reading comprehension of children with DLD should focus on elaborative inferencing skill. There are also clinical implications as the development of new standardized assessments differentiating between inference types is called for. PMID- 30286247 TI - Changes in English Past Tense Use by Bilingual School-Age Children With and Without Developmental Language Disorder. AB - Purpose: The purpose of this study is to examine changes in English past tense accuracy and errors among Spanish-English bilingual children with typical development (TD) and developmental language disorder (DLD). Method: Thirty-three children were tested before and after 1 year to examine changes in clinically relevant English past tense errors using an elicited production task. A mixed model linear regression using age as a continuous variable revealed a robust effect for age. A 4-way repeated-measures analysis of variance was conducted with age (young, old) and language ability group (TD, DLD) as between-subjects variables, time (Time 1, Time 2) and verb type (regular, irregular, and novel verbs) as within-subject variables, and percent accuracy as the dependent variable. Subsequently, a 4-way repeated-measures analysis of variance was conducted to measure the overall distribution of verb errors across 2 time points. Results: Overall, children produced regular and novel verb past tense forms with higher accuracy than irregular past tense verbs in an elicitation task. Children with TD were more accurate than children with DLD. Younger children made more improvement than older children from Time 1 to Time 2, especially in the regular and novel verb conditions. Bare stem and overregularization were the most common errors across all groups. Errors consisting of stem + ing were more common in children with DLD than those with TD in the novel verb condition. Discussion: Contrary to an earlier report (Jacobson & Schwartz, 2005), the relative greater difficulty with regular and novel verbs was replaced by greater difficulty for irregular past tense, a pattern consistent with monolingual impairment. Age was a contributing factor, particularly for younger children with DLD who produced more stem + ing errors in the novel verb condition. For all children, and particularly for those with DLD, an extended period for irregular past tense learning was evident. The results support a usage based theory of language acquisition and impairment. PMID- 30286248 TI - Factors Associated With Self-Reported Hearing Aid Management Skills and Knowledge. AB - Purpose: Hearing aid management describes the skills and knowledge required for the handling, use, care, and maintenance of the hearing aid. The importance of hearing aid management skills and knowledge is evidenced by their association with hearing aid outcomes. However, the nature of this association and the influence of participant factors on this association are unknown. Accordingly, the aims of the current study were to (a) investigate participant factors that influence hearing aid management skills and knowledge and (b) investigate the impact of hearing aid management skills and knowledge on hearing aid outcomes. Method: Factors associated with hearing aid management skills and knowledge were investigated through an e-mail- and paper-based self-report survey, including the Hearing Aid Skills and Knowledge Inventory (Bennett, Meyer, Eikelboom, & Atlas, 2018b) and the International Outcomes Inventory for Hearing Aids (Cox & Alexander, 2002). The study sample included 518 adult hearing aid owners, ranging in age from 18 to 97 years (M = 71 years, SD = 14 years), 61% male and 39% female, recruited from seven hearing clinics across Australia. Results: Participant factors found to be associated with hearing aid skills and knowledge included participants' age, gender, style of hearing aid, age of current hearing aid, and total years of hearing aid ownership. Higher levels of hearing aid management skills and knowledge were found to be associated with better hearing aid outcomes, specifically higher self-reported satisfaction with hearing aids, perceived benefit from hearing aids, and overall outcome of the hearing aid fitting as evaluated by the International Outcomes Inventory for Hearing Aids. Conclusions: Hearing aid management difficulties were greatest for older people, women, and owners of behind-the-ear style of hearing aids, suggesting that clinicians need to be cognizant of the additional needs for these three groups. The positive association between hearing aid outcomes and hearing aid skills and knowledge emphasizes the importance of education and training on hearing aid management for successful aural rehabilitation. PMID- 30286249 TI - Integrative Analysis of Programmed Death-Ligand 1 DNA, mRNA, and Protein Status and their Clinicopathological Correlation in Diffuse Large B-cell Lymphoma. AB - AIMS: The Protein expression of Programmed Death-Ligand 1 (PD-L1) has been recognized a poor prognostic biomarker in diffuse large B-cell lymphoma (DLBCL). We aim to detect PD-L1 DNA and mRNA status, and explore whether they contribute to protein expression and their clinicopathological correlation in DLBCL. METHODS AND RESULTS: In the study, we detected PD-L1 status in three different levels by Fluorescence in situ hybridization, RNA in situ hybridization and immunohistochemistry in 287 DLBCL samples with follow-ups, respectively. Their correlation and clinical pathological relevance was further analyzed. Our results showed that 1.7% (3/175) patients had PD-L1 amplification, 19.9% (57/287) PD-L1 mRNA high expression and 11.8% (34/287) high protein expression. Both mRNA and protein high expression of PD-L1 was significantly elevated in non-GCB than that in GCB DLBCL (P<0.05). In addition, the patients with PD-L1 mRNA or protein high expression but not DNA amplification have significantly poorer overall survival (OS) than that with PD-L1 low expression (P<0.05). Furthermore, we found that PD L1 mRNA and protein expression are highly correlated (P=0.012), which was observed in all three samples with PD-L1 DNA amplification. CONCLUSIONS: PD-L1 DNA amplification is a rare event, PD-L1 mRNA mainly contribute to the protein high expression, and the latter two will serve as important biomarkers for predicting prognosis and selecting patients for immunotherapy in DLBCL.

PMID- 30286250 TI - Lower body negative pressure to safely reduce intracranial pressure. AB - KEY POINTS: During long-term missions, some astronauts experience structural and functional changes of the eyes and brain which resemble signs/symptoms experienced by patients with intracranial hypertension. Weightlessness prevents the normal cerebral volume and pressure 'unloading' associated with upright postures on Earth, which may be part of the cerebral and ocular pathophysiology. By placing the lower body in a negative pressure device (LBNP) that pulls fluid away from cranial compartments, we simulated effects of gravity and significantly lowered pressure within the brain parenchyma and ventricle compartments. Application of incremental LBNP demonstrated a non-linear dose-response curve, suggesting 20 mmHg LBNP as the optimal level for reducing pressure in the brain without impairing cerebral perfusion pressure. This non-invasive method of reducing pressure in the brain holds potential as a countermeasure in space as well as having treatment potential for patients on Earth with traumatic brain injury or other pathology leading to intracranial hypertension. ABSTRACT: Patients with elevated intracranial pressure (ICP) exhibit neuro-ocular symptoms including headache, papilloedema and loss of vision. Some of these symptoms are also present in astronauts during and after prolonged space-flight where lack of gravitational stress prevents daily lowering of ICP associated with upright posture. Lower body negative pressure (LBNP) simulates the effects of gravity by displacing fluid caudally and we hypothesized that LBNP would lower ICP without compromising cerebral perfusion. Ten cerebrally intact volunteers were included: six ambulatory neurosurgical patients with parenchymal ICP-sensors and four former cancer patients with Ommaya-reservoirs to the frontal horn of a lateral ventricle. We applied LBNP while recording ICP and blood pressure while supine, and during simulated intracranial hypertension by 15 degrees head-down tilt. LBNP from 0 to 50 mmHg at increments of 10 mmHg lowered ICP in a non-linear dose dependent fashion; when supine (n = 10), ICP was decreased from 15 +/- 2 mmHg to 14 +/- 4, 12 +/- 5, 11 +/- 4, 10 +/- 3 and 9 +/- 4 mmHg, respectively (P < 0.0001). Cerebral perfusion pressure (CPP), calculated as mean arterial blood pressure at midbrain level minus ICP, was unchanged (from 70 +/- 12 mmHg to 67 +/ 9, 69 +/- 10, 70 +/- 12, 72 +/- 13 and 74 +/- 15 mmHg; P = 0.02). A 15 degrees head-down tilt (n = 6) increased ICP to 26 +/- 4 mmHg, while application of LBNP lowered ICP (to 21 +/- 4, 20 +/- 4, 18 +/- 4, 17 +/- 4 and 17 +/- 4 mmHg; P < 0.0001) and increased CPP (P < 0.01). An LBNP of 20 mmHg may be the optimal level to lower ICP without impairing CPP to counteract spaceflight-associated neuro ocular syndrome in astronauts. Furthermore, LBNP holds clinical potential as a safe, non-invasive method for lowering ICP and improving CPP for patients with pathologically elevated ICP on Earth.

AB - AIMS: Immunohistochemical (IHC) staining for cytokeratin (CK) 5/6, CD44 and CK20 has been significantly associated with the prognosis of urinary bladder urothelial carcinoma, and probably reflects its molecular characteristics. We aimed to investigate the IHC-based subgroups and their prognostic effects on non muscle-invasive papillary upper tract urothelial carcinoma (UTUC). METHODS AND RESULTS: IHC staining for CK5/6, CK20 and CD44 was analysed in 211 patients with non-muscle-invasive papillary UTUC. Staining was classified as showing a negative, positive or normal pattern. We found that CK5/6-negative, CD44-negative and CK20-positive tumours were distinctly high-risk subgroups that were associated with high grade (CK5/6-negative, P < 0.001; CD44-negative, P < 0.001; CK20-positive, P = 0.017) and frequent intravesical recurrence (CK5/6-negative, P = 0.002). Using survival analysis with Kaplan-Meier and log-rank tests, we found that these IHC subgroups were correlated with poor progression-free (CK5/6 negative, P = 0.001; CD44-negative, P = 0.009; CK20-positive, P = 0.031) and cancer-specific (CK5/6-negative, P = 0.009) survival. Furthermore, CK5/6 negativity was an independent prognostic factor for shorter progression-free (P = 0.009) and cancer-specific (P = 0.045) survival. CK5/6 improved Harrell's C indices for progression-free (0.68-0.77, P = 0.029) and cancer-specific (0.59 0.77, P < 0.001) survival. When markers were combined, luminal-like subtypes showed poor prognoses. CONCLUSIONS: We demonstrated that IHC staining for CK5/6, CD44 and CK20 was significantly associated with the clinicopathological characteristics and prognoses of patients with non-muscle-invasive papillary UTUC. The IHC subgroups may be correlated with the molecular characteristics of non-muscle-invasive papillary UTUC. PMID- 30286253 TI - Corticospinal excitability during shortening and lengthening actions with incremental torque output. AB - NEW FINDINGS: What is the central question of this study? The relationship between motor unit recruitment and firing rate has been related to the size of the corticospinal output with variations in the nervous system gain during isometric contractions. However, corticospinal behaviour with incremental torque output might differ during anisometric contractions owing to differences in neural control of anisometric contraction types. What is the main finding and its importance? Corticospinal excitability during lengthening contractions was smaller compared with shortening but increased with incremental torque output in a similar manner between contraction types. The relationship between motor unit recruitment and firing rates is probably the main determinant of the size of an evoked response with variations in system gain. ABSTRACT: The modulation of motor evoked potentials (MEPs), an index of corticospinal excitability, has been shown to increase during isometric contractions with incremental torque output in accordance with the contribution between motor unit recruitment and firing rate of the muscle to increases in required torque output. However, the motor unit strategy of the muscle might not be the only factor influencing this behaviour, because differences in pre- and postsynaptic control have been reported between lengthening and shortening or isometric contractions. In 30 healthy adults, MEPs were elicited in tibialis anterior during shortening and lengthening contractions at 15, 25, 50 and 80% of contraction-type-specific maximal voluntary contraction torque. Background EMG activity increased progressively with greater torque output (P < 0.001) but was similar between contraction types (P = 0.162). When normalized to the maximal muscle response, MEPs were greater during shortening compared with lengthening contractions (P = 0.004) and increased stepwise with increased contraction intensities (P = 0.001). These data show an increase in corticospinal excitability with torque output from lower to higher contraction intensities, suggesting a greater contribution of motor unit recruitment to increased nervous system gain in the tibialis anterior. Despite differences in corticospinal control of shortening and lengthening contractions, the data suggest that the corticospinal responses to increases in torque output are not dependent on contraction type, because corticospinal excitability increased to a similar extent during shortening and lengthening actions. Thus, it is likely that the relationship between motor unit recruitment and firing rate of the muscle is the main determinant of corticospinal output with variations in nervous system gain.

AB - A highly enantioselective (91- > 99% ee) Michael addition of alpha-nitroacetate to alpha,beta-unsaturated pyrazolamide was developed in the presence of a bifunctional squaramide. Satisfactory isolated yields (42%-99%) have been achieved with a wide range of alpha,beta-unsaturated pyrazolamides, albeit acceptor of this type displayed poor reactivity in the precedent reports. The adducts resulting from this protocol are useful synthetic intermediates for further synthetic modification. PMID- 30286256 TI - A new approach to pharmaceutical pricing based on patients' willingness to pay. AB - OBJECTIVES: Pharmaceutical pricing is an important and contentious issue in middle- and low-income countries. The present study evaluated a value-based pricing system for estimating the price of interferon-beta (IFN-beta). METHODS: Prices were estimated through the Willingness to Pay (WTP) system using the Discrete Choice Experiment (DCE) from the viewpoint of MS patients, levels of attributes and patients' willingness to pay for these attributes. RESULTS: The results indicate that the new approach to pricing medicines leads to more integrated prices than the current system. The current prices of four brands were higher than their pharmaceutical market price; the prices of other brands were consistent with it. CONCLUSION: Application of the proposed pricing system will help pharmaceutical companies make realistic price estimates of their products while accounting for patient preferences, which may enhance patients' adherence to treatment.

AB - Polylactide (PLA)-based amphiphilic block copolymers and their nanoassemblies designed with stimuli-responsive degradation (SRD) hold great potential as promising candidates for tumor-targeting drug delivery. However, most of the smart PLA-based nanoassemblies are designed to respond to a single stimulus (typically reduction or acidic pH). Herein, a new strategy is reported to synthesize PLA-based block copolymer micelles exhibiting dual SRD at dual locations (DL-DSRD). The strategy utilizes a combination of ring opening polymerization, controlled radical polymerization, and facile coupling reactions to synthesize an ABA-type PLA-based triblock copolymer with a hydrophilic polymethacrylate (A) and PLA (B) blocks. Incorporation of an acidic pH-responsive ketal linkage in the center of PLA block and reduction-responsive disulfide linkages at PLA/hydrophilic polymethacrylate blocks ensure the formation of smart nanoassemblies featured with ketal linkages in the PLA cores and disulfide linkages at core/corona interfaces, thus attaining DL-DSRD. Such dual acidic pH/reduction-responses at dual locations lead to not only shedding of coronas at interfaces but also destabilization of cores, resulting in the synergistic and accelerated release of encapsulated model drugs, compared with the single stimulus systems. These results, along with lower cytotoxicity, suggest that DL DSRD strategy can offer versatility in the development of tumor-targeting drug delivery nanocarriers. PMID- 30286259 TI - Adriamycin inhibits embryonic development in zebrafish through downregulation of Kruppel-like factor4. AB - Adriamycin is an effective anticancer drug used in a wide range of cancers. Anticancer drugs modulate oncogenes and nodal regulatory molecules that affect cell differentiation and organismal development. In this study, we explore the effect of adriamycin on Kruppel-like factor4 (Klf4), an essential pluripotent factor by choosing zebrafish embryos as a model system. Klf4 is involved in the regulation of cellular growth, proliferation, and differentiation. In zebrafish embryogenesis, Klf4 is a major regulator of differentiation of polster in the anterior mesendoderm region of cells into hatching gland cells. The importance of this study is to check the effect of adriamycin on embryonic development. We found, adriamycin dose dependently altered the gene expression level of Klf4 that occurs in parallel to its detrimental effect on hatching. Supportively, cathepsin L and cyclase-associated protein1 are the other two markers of hatching that are altered along with Klf4. PMID- 30286260 TI - Subunit Mass Analysis for Monitoring Multiple Attributes of Monoclonal Antibodies. AB - RATIONALE: Multi-Attribute Methods (MAMs) are appealing due to their ability to provide data on multiple molecular attributes from a single assay. If fully realized, such tests could reduce the number of assays required to support a product control strategy while providing equivalent or greater product understanding relative to the conventional approach. In doing so, MAMs have the potential to decrease development and manufacturing costs by reducing the number of tests in a release panel. METHODS: In this work, we report a MAM which is based on subunit mass analysis. RESULTS: The MAM assay is shown to be suitable for use as a combined method for identity testing, glycan profiling, and protein ratio determination for co-formulated monoclonal antibody (mAb) drugs. This is achieved by taking advantage of the high mass accuracy and relative quantification capabilities of intact mass analysis using quadrupole time of flight mass spectrometry (Q-TOF). Protein identification is achieved by comparing the measured masses of light chain (LC) and heavy chain (HC) of mAbs against their theoretical values. Specificity is based on instrument mass accuracy. Glycan profiling and relative protein ratios are determined by the relative peak intensities of the protein HC glycoforms and LC respectively. Results for these relative quantifications agree well with those obtained by the conventional hydrophilic interaction liquid chromatography (HILIC) and reversed phase LC methods. CONCLUSIONS: The suitability of this MAM method for use in a quality control setting is demonstrated through assessment specificity for mAb identity, and accuracy, precision, linearity and robustness for glycan profiling and ratio determination. Results from this study indicate that MAM with subunit mass analysis has the potential to replace three conventional methods widely used for mAb release testing including identification assay, glycosylation profiling, and ratio determination for co-formulated mAbs. PMID- 30286261 TI - Translating prenatal oral health clinical standards into dental education: results and policy implications. AB - OBJECTIVES: To evaluate characteristics of pregnant women served through the University of North Carolina's (UNC) prenatal oral health program (pOHP) dental clinic and community healthcare pathways to inform efforts in promoting prenatal oral health policies. METHODS: The pOHP provides medical and dental students and practitioners with interprofessional experiences caring for pregnant women. A retrospective chart audit captured 314 pregnant women who made appointments over 33 months. Descriptive statistics and bivariate comparisons were computed to assess factors associated with dental appointment attendance and treatment completion. RESULTS: There were 564 pregnant women, with mean age of 29 years and gestation of 25 weeks, referred to the pOHP dental clinic from UNC OB-GYN and 20 community sites. Only 56% (N = 314) scheduled an appointment. Of the 314 appointed women, 55% (N = 172) attended at least one appointment. The majority (87%) presented with acute and/or complex treatment needs. Medicaid status was positively associated with appointment attendance (P = 0.001). Less than half (42%) of the women completed treatment prior to delivery. Mean maternal age, gestational age, and weeks to estimated date of delivery (EDD) were not significantly associated with completed treatment. CONCLUSIONS: This study provides descriptive evidence of an academic, interprofessional program's ability to provide safety-net dental care to pregnant women in the state of North Carolina. Results underscore the need for dental services among pregnant women, signaling for promotion of prenatal oral health clinical standards and informing policy on the state and national levels to maximize dental coverage. PMID- 30286262 TI - The effects of partial amniotic carbon dioxide insufflation in an ovine model. AB - OBJECTIVE: We aim to assess the effect of partial amniotic carbon dioxide insufflation (PACI) at increasing pressures on fetal acid-base, fetal-placental perfusion, and fetal membrane morphology in an ovine model. METHOD: Pregnant ewes and fetuses were instrumented under isoflurane anesthesia at 105 days gestation (term 145 days) to monitor utero-placental blood flow, fetal and maternal blood pressure, heart rate, and blood gas status. One group (n = 6) was exposed to PACI (unheated dry CO2 ), involving 10 mm Hg stepwise increases in insufflation pressure (5 to 25 mm Hg), for 80 minutes followed by 20 minutes of desufflation. Un-insufflated controls (n = 5) were monitored for 100 minutes. At postmortem, fetal membranes were collected for histological analysis. RESULTS: PACI at 25 mm Hg caused severe fetal hypercapnia (PaCO2 = 143 +/- 5 vs 54 +/- 5 mm Hg, P < 0.001), acidosis (pH = 6.85 +/- 0.02 vs 7.25 +/- 0.02, P < 0.001), hypoxia (SaO2 = 31 +/- 4% vs 57 +/- 4%, P = 0.01), and reduced uterine artery flow (50 +/- 15 vs 196 +/- 13 mL/min/kg, P = 0.005) compared with controls. These effects were greater at higher PACI pressures. PACI resulted in leukocyte infiltration in the amnion (1.77 * 10-5 +/- 0.61 * 10-5 vs 0.38 * 10-5 +/- 0.19 * 10-5 cells/MUm2 , P = 0.04) and chorionic membranes (2.94 * 10-5 +/- 0.67 * 10-5 vs 0.84 * 10-5 +/- 0.42 * 10-5 cells/MUm2 , P = 0.01). CONCLUSION: Higher PACI pressures results in larger disturbances in fetal acid-base, uterine blood flow, and fetal membrane inflammation in sheep. Differences between human and sheep utero placental structure should be considered. PMID- 30286263 TI - Body mass index and sexual function in women with gynaecological cancer. AB - OBJECTIVES: To investigate the association between body mass index (BMI) and sexual functioning in gynaecologic cancer patients. To determine the association between socio-economic deprivation and sexual functioning. METHODS: This is a prospective cohort study on women undergoing surgery for suspected or proven gynaecological cancer between September 2014 and February 2016 in the Royal Cornwall Hospital Trust. Patients were invited to participate by completing the Female Sexual Function Index (FSFI) at three time points: preoperative, 3 months postoperative, and 1 year postoperative. A semiparametric model of the FSFI score was used to establish the association between BMI and sexual functioning. RESULTS: A total of 257 patients were approached of which 166 patients were included. Fifty-two patients (33.8%) were overweight (BMI, 25-29.9 kg/m2 ), 44 (28.6%) were obese (BMI, 30-39.9 kg/m2 ), and a further 20 (13.0%) morbidly obese (BMI >= 40 kg/m2 ). Overweight and obese women reported improved sexual functioning compared with normal-weight women in endometrial, ovarian, and vulvar cancers. Among cervical cancer, worse sexual functioning was seen in women with an increased BMI; however, this was not significant. Younger age was associated with improved sexual function, and sexual functioning was better postoperatively for all patients compared with preoperatively. There was no evidence of relationship between deprivation and sexual functioning in gynaecological cancer patients. CONCLUSION: Higher BMI is associated with improved sexual functioning in endometrial, ovarian, and vulvar cancer; however, this was not seen in cervical cancer patients. There is no evidence of correlation between deprivation and sexual functioning. PMID- 30286264 TI - miR-34 regulates reproduction by inhibiting the expression of MIH, CHH, EcR, and FAMeT genes in mud crab Scylla paramamosain. AB - Mud crab Scylla paramamosain is a commercially important species widely cultured in China. It is well known that the eyestalk regulates reproductive activities in crustaceans. In our previous research, we found that the miR-34 expression level in male eyestalk was significantly higher than that in females. Thus, we assumed that it may play an important role in regulating reproduction. In this study, we used bioinformatic tools to identify the target genes of miR-34 in eyestalk. Six reproduction-related genes with an intact 3'-untranslated region (UTR), including molt-inhibiting hormone (MIH), crustacean hyperglycemic hormone (CHH), vitellogenesis-inhibiting hormone, red pigment concentrating hormone, ecdysone receptor (EcR), and farnesoic acid methyltransferase (FAMeT) were identified. When the 3'-UTR plasmid vectors of the six genes were cotransfected with miR-34 mimics into 293FT cells, respectively, the luciferase activities of four genes (MIH, CHH, EcR, and FAMeT) were significantly decreased compared with that in the control group; on the contrary, when the six plasmid vectors were cotransfected with the miR-34 inhibitor respectively, the luciferase activities of four genes (MIH, CHH, EcR, and FAMeT) were significantly higher than that in the control group. When agomiR-34 and antagomiR-34 were injected into the eyestalk respectively in vivo, the expression levels of the MIH, CHH, EcR, and FAMeT genes were detected by a quantitative real-time polymerase chain reaction. The results showed that agomiR-34 suppressed the expression of the four genes, whereas antagomiR-34 enhanced their expression. These experimental results confirmed our hypothesis that miR-34 may indirectly regulate reproduction via binding to the 3' UTRs of MIH, CHH, EcR, and FAMeT genes and suppressing their expression. PMID- 30286265 TI - Does a Conjugation Site Affect Transport of Vitamin B12 -Peptide Nucleic Acid Conjugates into Bacterial Cells? AB - Gram-negative bacteria develop specific systems for the uptake of scarce nutrients, including vitamin B12 . These uptake pathways may be utilized for the delivery of biologically relevant molecules into cells. Indeed, it was recently reported that vitamin B12 transported an antisense peptide nucleic acid (PNA) into Escherichia coli and Salmonella Typhimurium cells. The present studies indicate that the conjugation site of PNA to vitamin B12 has an impact on PNA transport into bacterial cells. Toward this end, a specifically designed PNA oligomer has been tethered at various positions of vitamin B12 (central Co, R5' OH, c and e amide chains, meso position, and at the hydroxy group of cobinamide) by using known or newly developed methodologies and tested for the uptake of the synthesized conjugates by E. coli. Compounds in which the PNA oligonucleotide was anchored at the R5' -OH position were transported more efficiently than that of other compounds tethered at the peripheral positions around the corrin ring. Of importance is the fact that, contrary to mammalian organisms, E. coli also takes up cobinamide, which is an incomplete corrinoid. This selectivity opens up ways to fight bacterial infections. PMID- 30286266 TI - Anomalous Stoichiometry and Antiferromagnetic Ordering for the Extended Hydroxymanganese(II) cubes/hexacyanometalate-based. AB - The reaction of MnII(O2CMe)2 and NaCN or LiCN in water forms a light green insoluble material. Structural solution and Rietveld refinement of high resolution synchrotron powder diffraction data for this unprecedented, complicated compound of previously unknown composition revealed an alkali free ordered new structural motif with [MnII4(u3-OH)4]4+ cubes and octahedral [MnII(CN)6]4- ions interconnected in 3-D via MnII-N=C-MnII linkages. The composition is {[MnII(OH2)3][MnII(OH2)]3}(u3-OH)4][MnII(u-CN)2(CN)4]*H2O = [MnII4(u3-OH)4(OH2)6][MnII(u-CN)2(CN)4]*H2O, which is further simplified to [Mn4(OH)4][Mn(CN)6](OH2)7 (1). 1 has four high-spin (S = 5/2) MnII sites that are antiferromagnetically coupled within the cube and are antiferromagnetically coupled to six low-spin (S = 1/2) octahedral [MnII(CN)6]4- ions. Above 40 K the magnetic susceptibility, chi(T), can be fit the Curie-Weiss expression, chi ?(T - theta)-1, with theta = -13.4 K, indicative of significant antiferromagnetic coupling and 1 orders as an antiferromagnet at Tc = 7.8 K. PMID- 30286267 TI - Facilitators for maternity waiting home utilisation at Attat Hospital: a mixed methods study based on 45 years of experience. AB - OBJECTIVE: To describe facilitators for maternity waiting home (MWH) utilisation from the perspectives of MWH users and health staff. METHODS: Data collection took place over several time frames between March 2014 and January 2018 at Attat Hospital in Ethiopia, using a mixed-methods design. This included seven in-depth interviews with staff and users, three focus group discussions with 28 users and attendants, a structured questionnaire among 244 users, a 2-week observation period and review of annual facility reports. The MWH was built in 1973; consistent records were kept from 1987. Data analysis was done through content analysis, descriptive statistics and data triangulation. RESULTS: The MWH at Attat Hospital has become a well-established intervention for high-risk pregnant women (1987-2017: from 142 users of 777 total attended births [18.3%] to 571 of 3693 [15.5%]; range 142-832 users). From 2008, utilisation stabilised at on average 662 women annually. Between 2014 and 2017, total attended births doubled following government promotion of facility births; MWH utilisation stayed approximately the same. Perceived high quality of care at the health facility was expressed by users to be an important reason for MWH utilisation (114 of 128 MWH users who had previous experience with maternity services at Attat Hospital rated overall services as good). A strong community public health programme and continuous provision of comprehensive emergency obstetric and neonatal care (EmONC) seemed to have contributed to realising community support for the MWH. The qualitative data also revealed that awareness of pregnancy-related complications and supportive husbands (203 of 244 supported the MWH stay financially) were key facilitators. Barriers to utilisation existed (no cooking utensils at the MWH [198/244]; attendant being away from work [190/244]), but users considered these necessary to overcome for the perceived benefit: a healthy mother and baby. CONCLUSIONS: Facilitators for MWH utilisation according to users and staff were perceived high-quality EmONC, integrated health services, awareness of pregnancy-related complications and the husband's support in overcoming barriers. If providing high-quality EmONC and integrating health services are prioritised, MWHs have the potential to become an accepted intervention in (rural) communities. Only then can MWHs improve access to EmONC. PMID- 30286268 TI - Epidemiology of human adenovirus infection in children hospitalized with lower respiratory tract infections in Hunan, China. AB - To investigate the current genotypes of circulating human adenovirus (HAdV) strains, we molecularly genotyped HAdV in the nasopharyngeal aspirates (NPAs) of patients with acute lower respiratory tract infections (ALRTIs) and attempted to determine their associations with clinical symptoms. A total of 4751 NPA samples were collected from 4751 patients admitted to Hunan Provincial People's Hospital from September 2007 to March 2014, of which 447 (9.4%) samples were HAdV positive. Fourteen different HAdV types were identified; HAdV types 1 to 7 (HAdV 1-7) were identified in 95.7% of the 447 NPA samples with HAdV-7 and HAdV-3 being the most prevalent. In addition, 93.3% (417 of 447) of patients were younger than 5 years. The incidence of HAdV infection peaked in summer. Different HAdV types showed a predilection for different age groups and different seasonal distribution patterns. Coinfection of HAdVs and other respiratory viruses was detected in 63.3% (283 of 447) of the HAdV-positive samples. The most common clinical diagnosis was pneumonia and the most common symptoms were fever and cough. In comparison with children infected with HAdV-3 alone, those infected with HAdV-7 alone had an increased frequency of severe pneumonia involvement (11.6% vs 32.4%; P = 0.031), higher intensive care unit admission rates (7.0% vs 26.5%; P = 0.019), and a longer length of hospital stay (P = 0.03). Mixed infections in younger children were associated with a longer hospital stay (P = 0.023). Our results demonstrate the recent changes in the trends of circulating HAdV genotypes associated with ALRTIs in Hunan China. PMID- 30286269 TI - Lipid organization in xerosis: the key of the problem? AB - OBJECTIVE: Although xerosis is a common skin disorder among the population, there is no in vivo global study focusing on xerotic skin. Hence, the objective of this study was to characterize xerotic skin from the surface to the molecular scale with in vivo and non-invasive approaches. METHODS: For this purpose, 15 healthy volunteers with normal skin and 19 healthy volunteers with xerotic skin were selected by a dermatologist, thanks to a visual scorage. Firstly, the skin surface was characterized with biometric measurements. Then, the state of skin dryness was assessed by in vivo confocal microscopy. The molecular signature of xerotic skin was then determined by in vivo confocal Raman microspectroscopy. Finally, an identification of stratum corneum (SC) lipids was performed using Normal phase liquid chromatography (NP-LC) coupled to two detectors: Corona and High Resolution/Mass Spectroscopy (HR/MS). RESULTS: Results obtained at the skin surface displayed an increase in the transepidermal water loss (TEWL) and a decrease in the hydration rate in xerotic skin. Confocal microscopy revealed an alteration of the cell shape in xerotic skin. Moreover, confocal Raman microspectroscopy demonstrated directly in vivo and non-invasively the lack of organization and conformation of lipids in this skin. Finally, HPLC analyses revealed that the three ceramide sub-classes (NdS, NS and EOP) significantly decrease in xerosis. Altogether, these results identify parameters for the characterization of xerotic skin compared to normal. CONCLUSION: This study highlighted discriminative parameters from the surface to the molecular level in vivo and non-invasively between xerotic and normal skins. These results will be useful for the development of new cosmetic active ingredients dedicated to xerotic skin. PMID- 30286270 TI - Menstrual hygiene management and school absenteeism among adolescent students in Indonesia: evidence from a cross-sectional school-based survey. AB - OBJECTIVE: Assess prevalence of menstrual hygiene management (MHM) knowledge and practices among adolescent schoolgirls in Indonesia, and assess factors associated with poor MHM and school absenteeism due to menstruation. METHODS: A cross-sectional survey enrolled a representative sample of urban and rural school going girls aged 12-19 years in four provinces of Indonesia. A semi-structured, self-administered questionnaire obtained socio-demographic characteristics, knowledge, practices and attitudes related to menstruation, MHM, and school absenteeism. School water, sanitation and hygiene (WASH) facilities were also assessed. Univariate weighted population prevalence was estimated and multivariable logit regression analyses applied to explore associations. RESULTS: A total of 1,159 adolescent girls with a mean age of 15 years (sd=1.8) participated. Most girls (90.8%, 95% confidence interval (95%CI)=79.7-96.1) had reached menarche. Over half (64.1%, 95%CI=49.9-76.2) reported poor MHM practices, and 11.1% (95%CI=8.1-15.2) had missed one or more days of school during their most recent menstrual period. Poor MHM practices were associated with rural residence (AOR=1.73, 95%CI=1.13-2.64), province (various AOR), lower school grade (AOR=1.69, 95%CI=1.05-2.74), and low knowledge of menstruation (AOR=3.49, 95%CI1.61-7.58). Absenteeism was associated with living in rural areas (AOR=3.96, 95%CI=3.02-5.18), province (various AOR), higher school grade (AOR=3.02, 95%CI=2.08-4.38), believing menstruation should be kept secret (AOR=1.47, 95%CI=1.03-2.11), experiencing serious menstrual pain (AOR=1.68, 95%CI=1.06-2.68) and showed mixed associations with school WASH facilities. CONCLUSIONS: High prevalence of poor MHM and considerable school absenteeism due to menstruation among Indonesian girls highlight the need for improved interventions that reach girls at a young age and address knowledge, shame and secrecy, acceptability of WASH infrastructure and menstrual pain management.

AB - OBJECTIVE: To investigate the seroprevalence of Sarcocystosis in the local communities of Pangkor and Tioman islands, Malaysia, by using antigenic recombinant surface antigens 2 and 3 from Sarcocystis falcatula (rSfSAG2 and rSfSAG3) as the target proteins via Western blot and ELISA assays. METHODS: SfSAG2 and SfSAG3 genes were isolated from S. falcatula and expressed in Escherichia coli expression system. A total of 348 serum samples [volunteers from both islands (n = 100), non-Sarcocystis parasitic infections patients (n = 50) and healthy donors (n = 100)] were collected and tested with purified SfSAGs in Western blot and ELISA assays to measure the seroprevalence of human sarcocystosis. RESULTS: None of the sera in this study reacted with rSfSAG2 by Western blot and ELISA. For rSfSAG3, relatively high prevalence of sarcocystosis was observed in Tioman Island (75.5%) than in Pangkor Island (34%) by Western blot. In ELISA, the different prevalence rate was observed between Tioman Island (43.8%) and Pangkor Island (37%). The prevalence rate in other parasitic infections (amoebiasis, cysticercosis, filariasis, malaria, toxocariasis and toxoplasmosis) was 30% by Western blot and 26% by ELISA. Only 8% (by Western blot) and 10% (by ELISA) of healthy donors showed reactivity towards rSfSAG3. CONCLUSION: This is the first study reporting a seroprevalence of sarcocystosis in Pangkor and Tioman Islands, Malaysia. The combination of Western blot and ELISA is suitable to be used for serodiagnosis of sarcocystosis. With further evaluations, SfSAG3 can potentially be used to confirm infection, asymptomatic screening, surveillance and epidemiological studies.

AB - Highly efficient earth-abundant electrocatalysts for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) are of great importance for renewable energy conversion systems. Herein, hollow porous heterometallic phosphide nanocubes are developed as a highly active and robust catalyst for electrochemical water splitting via one-step phosphidation of a NiCoFe Prussian blue analogue. Through modulation of the composition of metals in the precursors, the optimal NiCoFeP exhibiting increased electrical conductivity and abundant electrochemically active sites, leading to high electrocatalytic activities and outstanding kinetics for both HER and OER, is successfully obtained. NiCoFeP shows low overpotentials of 273 mV for OER and 131 mV for HER at a current density of 10 mA cm-2 and quite low Tafel slopes of 35 mV dec-1 for OER and 56 mV dec-1 for HER.

AB - Gelatin methacryloyl (acetyl) (GM(A)) is increasingly investigated for various applications in life sciences and medicine, for example, drug release or tissue engineering. Gelatin type A and type B are utilized for GA M(A) and GB M(A) preparation, but the impact of gelatin raw material on modification reaction and resulting polymer properties is rather unknown so far. Therefore, the degrees of modification (DMA) and physicochemical properties of five GA M(A) and GB M(A) derivatives are compared: The degrees of methacryloylation (0.32-0.98 mmol g-1 ) are indistinguishable for GA M(A) and GB M(A) as are the sol-gel temperatures. Isoelectric points, solution viscosities, and hydrodynamic radii which are distinct for GA and GB, converge with increasing DMA. Interestingly, differences are measured for the storage moduli and equilibrium degrees of swelling of respective GA and GB derivative-based hydrogels, in spite of their comparable DMA. This underlines the importance of GM(A) characterization beyond the modification degree. PMID- 30286275 TI - Emergence of New Density-Strength Scaling Law in 3D Hollow Ceramic Nanoarchitectures. AB - Density-strength tradeoff appears to be an inherent limitation for most materials and therefore design of cell topology that mitigates strength decrease with density reduction has been a long-lasting engineering pursue for porous materials. Continuum-mechanics-based analyses of mechanical responses of conventional porous materials with bending-dominated structures often give the density-strength scaling law following the power-law relationship with an exponent of 1.5 or higher, which consequentially determines the upper bound of the specific strength for a material to reach. In this work, a new design criterion capable of significantly abating strength degradation in lightweight materials is presented, by successfully combining the size-induced strengthening effect in nanomaterials with the architectural design of cellular porous materials. Hollow-tube-based 3D ceramic nanoarchitectures satisfying such criterion are fabricated in large area using proximity field nano-patterning and atomic layer deposition. Experimental data from micropillar compression confirm that the strengths of these nanoarchitectural materials scale with relative densities with a power-law exponent of 0.93, a hardly observable value in conventional bending-dominated porous materials. This discovery of a new density strength scaling law in nanoarchitectured materials will contribute to creating new lightweight structural materials attaining unprecedented specific strengths overcoming the conventional limit.

AB - Quick but accurate testing and on-the-spot monitoring of cocaine in oral fluids and urine continues to be an important toxicological issue. In terms of drug testing, a number of devices have been introduced into the market in recent decades, notably for workplace inspection or roadside testing. However, these systems do not always fulfill the requirements in terms of reliability, especially when low cut-off levels are required. With respect to surface water, the presence of anthropogenic small organic molecules such as prescription and over-the-counter pharmaceuticals as well as illicit drugs like cannabinoids, heroin, or cocaine, has become a challenge for scientists to develop new analytical tools for screening and on-site analysis because many of them serve as markers for anthropogenic input and consumer behavior. Here, a modular approach for the detection of cocaine is presented, integrating an electrochemical enzyme linked immunosorbent assay (ELISA) performed on antibody-grafted magnetic beads in a hybrid microfluidic sensor utilizing flexible tubing, static chip and screen printed electrode (SPE) elements for incubation, recognition, and cyclic voltammetry measurements. A linear response of the sensor vs. the logarithm of cocaine concentration was obtained with a limit of detection of 0.15 ng/L. Within an overall assay time of 25 minutes, concentrations down to 1 ng/L could be reliably determined in water, oral fluids, and urine, the system possessing a dynamic working range up to 1 mg/L. PMID- 30286277 TI - Automated Scalpel Patterning of Solution Processed Thin Films for Fabrication of Transparent MXene Microsupercapacitors. AB - A simple and generic strategy is proposed to pattern thin films deposited by a solution processable route. A soft approach based on an automated scalpel technique is developed to engrave thin films in a single step for sculpting functional planar devices. MXenes-the emerging family of 2D transition metal carbides and nitrides-combine metallic conductivity and hydrophilicity, enabling solution processing of transparent conducting electrodes (TCEs) under ambient conditions. Scalable dip coating is employed to process titanium carbide, Ti3 C2 , MXene thin films with excellent optoelectronic properties, achieving electrical Figure of merit up to 14. Automated scalpel engraving is adopted to fabricate transparent and semi-transparent MXene microsupercapacitors in a single step, hitherto not reported. Combining TCE and pseudocapacitive characteristics, MXene devices show excellent capacitive storage capabilities at high rates, without the aid of external metal current collectors. This technique allows for maskless patterning of solution processed thin films without losing intrinsic physicochemical properties and can be extended to fabricate heterostructured hybrid devices out of solution processable materials. PMID- 30286278 TI - Effect of recipient gender and donor-specific antibodies on antibody-mediated rejection after heart transplantation. AB - Gender-difference regarding antibody-mediated rejection (AMR) after heart transplantation has been described. However, no study accounted for the presence of preformed donor-specific antibodies (pfDSA), a known risk factor of AMR, more common among women than men. In a single-institution 6-year cohort (2010-2015), time to AMR was assessed, comparing men with women by survival analysis with a 1 year death-censored follow-up. All AMRs were biopsy proven. Confounding variables that were accounted for included mean intensity fluorescence (MFI) of pfDSA, recipient age, HLA-, size- and sex-mismatch. 463 patients were included. Overall incidence of AMR was 10.3% at 1 year. After adjusting for confounding variables, independent risk factors of AMR were female recipient gender (adjusted hazard ratio [adj. HR] = 1.78 [1.06-2.99]), P = .03) and the presence of pfDSA (adj. HR = 3.20 [1.80-5.70], P < .001). This association remained significant when considering pfDSA by their MFI; female recipient gender had an adj. HR = 2.2 (P = .026) and MFI of pfDSA (per 1 MFI-increase) adj. HR = 1.0002 (P < .0001). In this cohort, women were at higher risk of AMR than men and this risk increase was additive to that of pfDSA. These findings may suggest a gender-related difference in the severity of pfDSA. PMID- 30286279 TI - Zinc-Incorporated Microporous Molecular Sieve for Mild Catalytic Hydrolysis of gamma-Valerolactone: A New Selective Route for Biomass Conversion. AB - gamma-Valerolactone (GVL) is regarded as a key platform molecule in the production of fine chemicals such as pentenoic acid (PA) from biomass. Although PA is believed to be the key intermediate in solid-acid-catalyzed reactions of GVL, due to subsequent facile decarboxylation reactions further alkene products are formed. Here, by tailoring the acidity of Bronsted acid sites in an aluminophosphate (AlPO) molecular sieve through incorporation of Zn2+ into the framework, we access a new selective and effective catalyst for GVL conversion to PA. PMID- 30286281 TI - Carbon-Dot-Based Heterojunction for Engineering Band-Edge Position and Photocatalytic Performance. AB - A photocatalytic reaction is always governed by energy band configuration of the catalyst, but its modulation is challenging. Here, the adjustment of band-edge positions of Ag3 PO4 through fluorescent carbon dots is reported for the first time. Both Ag3 PO4 and carbon dots which keep the similar sizes constitute a heterojunction. Such heterostructure not only promotes visible light absorption, photogenerated charge separation, and transfer, but it also transforms photocatalytic activity of Ag3 PO4 from photooxidation to photoreduction due to the huge changes of band-edge positions. In addition, the heterojunction structure of carbon dots and Ag3 PO4 exhibits unique temperature-responsive photocatalytic activities and higher photocatalytic stability than the pure Ag3 PO4 . According to the contrast experiments and related characterizations, the possible mechanism of photocatalytic reaction is proposed. Therefore, this work offers an alternative route for adjusting energy band positions or tuning photocatalytic performance as well as for preparing novel carbon-dot-based heterostructure. PMID- 30286280 TI - Radiofrequency-Triggered Drug Release from Nanoliposomes with Millimeter-Scale Resolution Using a Superimposed Static Gating Field. AB - Drug delivery to a specific site in the body typically relies on the use of targeting agents that recognize a unique biomarker. Unfortunately, it is often difficult to identify unique molecular signatures that exist only at the site of interest. An alternative strategy is to deliver energy (e.g., light) to locally trigger release from a drug carrier; however, the use of this approach is limited because energy delivery to deep tissues is often impractical or invasive. In this work, radiofrequency-responsive superparamagnetic iron oxide nanoparticles (SPIONs) are used to trigger drug release from nanoscale vesicles. Because the body is inherently nonmagnetic, this approach allows for deep tissue targeting. To overcome the unfavorable meter-scale diffraction limit of SPION-compatible radiofrequency (RF) fields, a strong static gating field containing a sharp zero point is superimposed on the RF field. Only drug carriers that are at or near the zero point are susceptible to RF-triggered drug release, thereby localizing drug delivery with millimeter-scale resolution. This approach induces >40% drug release from thermally responsive doxorubicin-loaded liposomes within a 3.2 mm radius of the zero point with <10% release in the surrounding area, leading to a >2.5 therapeutic index in Huh 7 hepatocellular carcinoma cells. PMID- 30286282 TI - Nucleus of Circulating Tumor Cell Determines Its Translocation Through Biomimetic Microconstrictions and Its Physical Enrichment by Microfiltration. AB - The mechanism of cells passing through microconstrictions, such as capillaries and endothelial junctions, influences metastasis of circulating tumor cells (CTCs) in vivo, as well as size-based enrichment of CTCs in vitro. However, very few studies observe such translocation of microconstrictions in real time, and thus the inherent biophysical mechanism is poorly understood. In this study, a multiplexed microfluidic device is fabricated for real-time tracking of cell translocation under physiological pressure and recording deformation of the whole cell and nucleus, respectively. It is found that the deformability and size of the nucleus instead of the whole cell dominate cellular translocation through microconstrictions under a normal physiological pressure range. More specifically, cells with a large and stiff nucleus are prone to be blocked by relatively small constrictions. The same phenomenon is also observed in the size based enrichment of CTCs from peripheral blood of metastatic cancer patients. These findings are different from a popular viewpoint that the size and deformability of a whole cell mainly determine cell translation through microconstrictions, and thus may elucidate interactions between CTCs and capillaries from a new perspective and guide the rational design of size-based microfilters for rare cell enrichment. PMID- 30286283 TI - Nitride-Based Microlight-Emitting Diodes Using AlN Thin-Film Electrodes with Nanoscale Indium/Tin Conducting Filaments. AB - Microlight-emitting diodes (uLEDs) are emerging solutions for both high-quality displays and lighting technologies. However, the overall light output power density of these devices is low, as the emission area is shielded by the p electrodes required for current injection. In this study, instead of the more conventionally used indium tin oxide (ITO), an AlN thin film with nanoscale conducing filaments (CFs) is used, referred to as CF-AlN, as a transparent conducting electrode (TCE), to enhance the output power density from the same emission area. As a result of this modification, the electroluminescence intensity is enhanced by 10% at an injection current of 10 mA, and the current density is improved by 13% at a forward voltage of 4.9 V, in comparison to the parameters observed with ITO-based uLEDs. This improvement is attributed to the higher transmittance of CF-AlN TCEs, together with efficient hole injection from the p-electrode into the light-emitting layer, through the CFs formed in the AlN layer. In addition, using transmission electron microscopy analyses, the origin of the CFs is directly identified as the diffusion of In and Sn ions, which provides critical insight into the conduction mechanism of AlN-based TCEs. PMID- 30286284 TI - Simultaneous Determination of Uranium and Depleted Uranium Isotopic Ratio Using Inductively Coupled Mass Spectrometry. AB - We have developed and validated a method for the simultaneous quantitative measurement of total uranium (TU) and uranium 235 U/238 U isotopic ratio (UIR) in urine by inductively coupled plasma mass spectrometry (ICP-MS) using a Thermo Scientific iCAP-Q instrument. The performance characteristics of the assay were determined to be in compliance with clinical laboratory standards. The assay was linear in the concentration range of 1.0 to 500.0 ng/liter TU. The method was precise and accurate with limits of detection of 2.5 ng/liter for TU and 9.8 ng/liter for UIR. The accuracy was >93% and the coefficient of variation (% CV) was <5.0% for both TU and UIR. All results were within established guidelines and agreed-upon criteria, and the results fell within the certified range for the reference controls. The method has thus been shown to be effective as a simple, precise, and sensitive analytical technique for testing urine samples. (c) 2018 by John Wiley & Sons, Inc. PMID- 30286285 TI - Surfactant-Stripped Micelles of Near Infrared Dye and Paclitaxel for Photoacoustic Imaging Guided Photothermal-Chemotherapy. AB - Development of nanoagents with strong near-infrared (NIR) absorbance and high photothermal conversion capacity is highly desired for efficient photoacoustic (PA) imaging and photothermal therapy of cancers. Herein, surfactant-stripped micelles with photostable near-infrared dye, beta-thiophene-fused BF2 azadipyrromethene (aza-BDTP), are prepared in the presence of paclitaxel (PTX) with Pluronic F127 as the surfactant. Distinct from hydrophobic aza-BDTP and PTX, the obtained surfactant-stripped micelles aza-BDTP/PTX show excellent solubility, physiological stability, and high loading efficiencies for corresponding aza-BDTP and PTX. Intriguingly, these aza-BDTP/PTX micelles exhibit high photothermal conversion efficiency at 33.9%, significantly higher than 16.9% for bare aza-BDTP molecules, owing to aggregation-induced quenching of aza-BDTP fluorescence. With excellent photostability, aza-BDTP/PTX micelles appear to be a highly stable photoacoustic imaging probe and show efficient tumor accumulation as visualized under photoacoustic imaging upon intravenous injection. After being irradiated with a 785 nm laser, 4T1 tumors on the mice with systemic administration of aza BDTP/PTX micelles are fully eradiated without any recurrences within 60 d. This work presents a general method for efficient encapsulation of hydrophobic aza BDTP and PTX, obtaining hybrid aza-BDTP/PTX micelles as promising nanotheranostics for imaging guided cancer combination therapy. PMID- 30286286 TI - Emergence of letermovir resistance in a lung transplant recipient with ganciclovir-resistant cytomegalovirus infection. AB - Following a year of valganciclovir prophylaxis, a lung transplant recipient developed cytomegalovirus (CMV) infection that became resistant to ganciclovir, as confirmed by detection of UL97 kinase mutation M460V and a previously uncharacterized UL54 DNA polymerase mutation L516P. The latter mutation is now shown to confer ganciclovir and cidofovir resistance. As predicted from the viral genotype, foscarnet therapy was effective, but resumption of valganciclovir as secondary prophylaxis resulted in a plasma viral load rebound to 3.6 log10 copies/mL several weeks later. Valganciclovir was then replaced by letermovir, resulting in gradual viral load reduction in the first 5 weeks to below the quantitation limit (2.7 log10 copies/mL) for 1 week, followed by 10 weeks of rising viral loads reaching 4.3 log10 copies/mL while on letermovir. At this point, CMV genotypic testing revealed UL56 mutation C325Y, which confers absolute resistance to letermovir. Retreatment with foscarnet was successful. This case adds to the considerable list of proven ganciclovir resistance mutations, and provides an early experience with letermovir resistance after off-label therapeutic use. This experience is consistent with in vitro observations of rapid emergence of letermovir-resistant CMV after drug exposure. PMID- 30286287 TI - A-Crater-within-a-Crater Approach for Secondary Ion Mass Spectrometry Evaluation of the Quality of Interfaces of Multilayer Devices. AB - Further development and optimization of modern optoelectronic devices requires fast and reliable procedures that may evaluate the quality of interfaces. For thick multilayer devices, mixing effect may significantly prevent proper interpretation of secondary ion mass spectrometry depth profiles especially if a region of interest is located far from the sample surface. In this work, we present how to overcome this problem with a so-called a-crater-within-a-crater approach. In this notion, a high energetic primary ion beam is used to rapidly remove most of the material forming a large crater. Then, the energy is significantly reduced and a new smaller crater is formed at the bottom of the previous one. Close to the region of interest, the impact energy is decreased to 150 eV and thus an interface can be analyzed with minimal mixing effect and thus its quality can be adequately assessed. Usefulness of this approach is tested on an epitaxial structure of a triple-junction solar cell and reliable information about the structure imperfection has been obtained: p and n dopants in the tunnel junction overlapped, deteriorating the operation of the device.

AB - Amorphous EuB6 was successfully prepared having a high specific surface area (221.3 m2 g-1) via the reaction between EuCl3 and B2H6 in the presence of liquid plasma in an ionic liquid environment. The material exhibits an immediate, lasting, and highly selective response toward formaldehyde at room temperature with a detection limit of 50 ppb. The good sensing performance of the amorphous EuB6 material is attributed to the strong interaction between formaldehyde and the increased number of accessible electron-rich surface Eu sites. PMID- 30286289 TI - Isotropic Atomic Layer Etching of ZnO Using Acetylacetone and O2 Plasma. AB - Atomic layer etching (ALE) provides Angstrom-level control over material removal and holds potential for addressing the challenges in nanomanufacturing faced by conventional etching techniques. Recent research has led to the development of two main classes of ALE: ion-driven plasma processes yielding anisotropic (or directional) etch profiles and thermally driven processes for isotropic material removal. In this work, we extend the possibilities to obtain isotropic etching by introducing a plasma-based ALE process for ZnO which is radical-driven and utilizes acetylacetone (Hacac) and O2 plasma as reactants. In situ spectroscopic ellipsometry measurements indicate self-limiting half-reactions with etch rates ranging from 0.5 to 1.3 A/cycle at temperatures between 100 and 250 degrees C. The ALE process was demonstrated on planar and three-dimensional substrates consisting of a regular array of semiconductor nanowires (NWs) conformally covered using atomic layer deposition of ZnO. Transmission electron microscopy studies conducted on the ZnO-covered NWs before and after ALE proved the isotropic nature and the damage-free characteristics of the process. In situ infrared spectroscopy measurements were used to elucidate the self-limiting nature of the ALE half-reactions and the reaction mechanism. During the Hacac etching reaction that is assumed to produce Zn(acac)2, carbonaceous species adsorbed on the ZnO surface are suggested as the cause of the self-limiting behavior. The subsequent O2 plasma step resets the surface for the next ALE cycle. High etch selectivities (~80:1) over SiO2 and HfO2 were demonstrated. Preliminary results indicate that the etching process can be extended to other oxides such as Al2O3.

AB - In the current scenario, nanotechnological applications in the agriculture sector showing potential impacts on the improvement of plant growth in terms of protection and safety are at a very nascent stage. The present study deals with the synergistic role of zinc (Zn) and multiwalled carbon nanotubes (MWCNTs) synthesized as a zinc oxide (ZnO)/MWCNT nanocomposite, a prospective applicant to modulate the micronutrient supply and enhance the growth of onion seeds, thereby replacing harmful, unsafe chemical fertilizers. To the best of our knowledge, this is the first report wherein MWCNTs have been envisaged as a micronutrient distributor and a nutrient stabilizer enhancing the growth of onion plant under arid conditions. The growth trend of onion seeds was evaluated in an aqueous medium with varied concentrations of (i) MWCNTs, (ii) zinc oxide nanoparticles, and (iii) ZnO/MWCNT nanocomposites. ZnO/MWCNT nanocomposites with 15 MUg/mL concentration displayed the best seedling growth with the maximum number of cells in telophase. A significant growth trend with increased concentration of ZnO/MWCNTs displayed no negative impact on plant growth in contrast to that with the use of MWCNTs. The synergistic impact of Zn nanoparticles and MWCNTs in ZnO/MWCNT nanocomposites on the rate of germination was explained via a mechanism supported by scanning transmission electron microscopy.

AB - Although procyanidins constitute a unique class of polymeric plant secondary metabolites with a variety of biological properties including potent antioxidant activity, structure determination has been challenging, and structures of many complex procyanidins remain uncertain. To expedite the characterization of procyanidins, negative ion matrix-assisted laser desorption ionization high energy collision-induced dissociation tandem time-of-flight (MALDI-ToF/ToF) mass spectra of 20 isolated procyanidins containing catechin and epicatechin subunits with degrees of polymerization up to five were obtained and evaluated. Structurally significant fragmentation pathways of singly charged, deprotonated molecules were identified representing quinone methide, heterocyclic ring fission, and retro-Diels-Alder fragmentation. The interpretation of the tandem mass spectra for sequencing A-type, B-type, mixed-type, linear, and branched procyanidins is explained using specific examples of each.

AB - Chronic hepatitis B virus (HBV) infection is a serious public health burden and current therapies cannot achieve satisfactory cure rate. There are high unmet medical needs of novel therapeutic agents with differentiated mechanism of action (MOA) from the current standard of care. RG7834, a compound from the dihydroquinolizinone (DHQ) chemical series, is a first-in-class highly selective and orally bioavailable HBV inhibitor which can reduce both viral antigens and viral DNA with a novel mechanism of action. Here we report the discovery of RG7834 from a phenotypic screening and the structure-activity relationship (SAR) of the DHQ chemical series. RG7834 can selectively inhibit HBV but not other DNA or RNA viruses in a virus panel screening. Both in vitro and in vivo profiles of RG7834 are described herein, and the data support further development of this compound as a chronic HBV therapy. PMID- 30286293 TI - Characterization of an Unusual Glycerate Esterification Process in Vioprolide Biosynthesis. AB - Bacteria produce a large number of secondary metabolites with extraordinary chemical structures and bioactivities. Vioprolides are promising anticancer and antifungal lead compounds produced by the myxobacterium Cystobacter violaceus Cb vi35, which are initially synthesized as acylated precursors (previoprolides) by nonribosomal peptide synthetases (NRPS). Here, we describe and characterize an unprecedented glycerate esterification process in the biosynthesis of vioprolides. In vitro biochemical investigations revealed that the fatty acyl chain of previoprolides is adenylated by the starting fatty acyl-AMP ligase (FAAL) domain, while the glycerate moiety is incorporated by the FkbH domain. An unusual ester-bond forming condensation domain is shown responsible for the acylation of glycerate. LC-MS analysis and bioactivity assays suggest that the acylation serves for directed membrane transport rather than representing a prodrug mechanism. PMID- 30286294 TI - Morphological Transitions of Water Channels Induced by Vertical Vibrations. AB - We report the results of comprehensive experiments and numerical calculations of interfacial morphologies of water confined to the hydrophilic top face of rectangular posts subjected to vertical vibrations. In response to mechanical driving, an initially flat liquid channel is collected into a liquid bulge that forms in the center of the rectangular post if the acceleration exceeds a certain threshold. The bulge morphology persists after the driving is switched off, in agreement with the morphological bistability of static interfacial shapes on posts with large length-to-width ratios. In a narrow frequency band, the channel does not decay into a bulge at any acceleration amplitude, but displays irregular capillary waves and sloshing instead. On short posts, however, a liquid bulge can be dynamically sustained through vertical vibrations but quickly decays into a homogeneous channel after the external driving is stopped. To explain the dynamic bulging of the liquid interface, we propose an effective lifting force pulling on the drop's slowly moving center of mass in the presence of fast oscillation modes. PMID- 30286295 TI - Confined Structures and Selective Mass Transport of Organic Liquids in Graphene Nanochannels. AB - Selective transport of liquids is an important process in the energy and environment industry. The increased energy consumption and the demands of clean water and fossil fuels have urged the development of high-performance membrane technologies. Nanoscale channels with the critical size for molecular sieving and atomistically smooth walls for significant boundary slippage are highly promising to balance the tradeoff between permeability and selectivity. In this work, we explore the molecular structures and dynamics of organic solvents and water, which are confined within nanoscale two-dimensional galleries between graphene or graphene oxide sheets. Molecular dynamics simulation results show that the layered order and significant interfacial slippage are universal for all molecular liquids, leading to notable flow enhancement for channels with a width of few nanometers, in the order of ethylene glycol > butanol > ethanol > hexane > toluene > water > acetone. The extracted dependence of permeability, selectivity on the channel width, and properties of molecular liquids clarify the underlying mechanisms of selective mass transport in nanofluidics, which help to understand and control the filtration and separation processes of molecular liquids. The performance of graphene oxide membranes for permeation and filtration is finally discussed based on the calculated flow resistance for pressure-driven flow or molecular diffusivity for diffusive flow, as well as the solubility and wettability of membranes. PMID- 30286296 TI - Human iPS Cell-Derived Patient Tissues and 3D Cell Culture Part 1: Target Identification and Lead Optimization. AB - Human-induced pluripotent stem cells (HiPSCs), and new technologies to culture them into functional cell types and tissues, are now aiding drug discovery. Patient-derived HiPSCs can provide disease models that are more clinically relevant and so more predictive than the currently available animal-derived or tumor cell-derived cells. These cells, consequently, exhibit disease phenotypes close to the human pathology, particularly when cultured under conditions that allow them to recapitulate the tissue architecture in three-dimensional (3D) systems. A key feature of HiPSCs is that they can be cultured under conditions that favor formation of multicellular spheroids or organoids. By culturing and differentiating in systems mimicking the human tissue in vivo, the HiPSC microenvironment further reflects patient in vivo physiology, pathophysiology, and ultimately pharmacological responsiveness. We assess the rationale for using HiPSCs in several phases of preclinical drug discovery, specifically in disease modeling, target identification, and lead optimization. We also discuss the growing use of HiPSCs in compound lead optimization, particularly in profiling compounds for their potential metabolic liability and off-target toxicities. Collectively, we contend that both approaches, HiPSCs and 3D cell culture, when used in concert, have exciting potential for the development of novel medicines. PMID- 30286297 TI - DIRECT INHIBITORY EFFECT OF FLAXSEED ON PORCINE OVARIAN GRANULOSA CELL FUNCTIONS. AB - Flaxseed is useful as a functional food and alternative medicine owing to its beneficial health effects. Its action on ovarian cell functions and interrelationships with the upstream hormonal regulators remain unknown. Our aim was to examine the direct influence of flaxseed extract on basal porcine ovarian functions (proliferation, apoptosis), leptin release, and response to insulin like growth factor I (IGF-I). First, we examined the effect of flaxseed extract on the accumulation of proliferation (PCNA) and apoptosis (bax) marker and on leptin release in cultured porcine ovarian granulosa cells. Next, granulosa cells were cultured with IGF-I with and without flaxseed extract and analyzed for PCNA and bax accumulation by quantitative immunocytochemistry, whereas leptin was analyzed by RIA. Flaxseeds decreased the accumulation of proliferation marker and increased that of the apoptosis marker at all doses and reduced leptin output at 100 ug/ml. On the contrary, IGF-I promoted PCNA and suppressed bax. Flaxseed did not modify IGF-I action on these parameters. Thus, we showed flaxseed action on porcine reproductive processes, with a direct effect on the ovary and flaxseed ability to affect ovarian cell proliferation, apoptosis, and leptin release. Furthermore, we confirmed the pro-proliferating and anti-apoptosis action of IGF I, but indicated that flaxseed action on ovarian cell proliferation and apoptosis are not due to changes in their response to IGF-I. The potential direct anti reproductive action of flaxseed needs to be confirmed properly in in-vivo experiments and thereafter considered during its application in nutrition, medicine, and animal production. PMID- 30286298 TI - Military Deployments and Suicide: A Critical Examination. AB - Deployment to a combat zone is a fundamental mission for most military forces, but prior research suggests that there is a complex and nuanced association between deployment and related risk factors for suicide. Deployment and combat experiences vary greatly among military personnel and can affect a variety of protective and risk factors for suicide. This article offers a critical examination of the association among modern U.S. military deployments, suicide attempts, and death while considering the context of a prominent theory of suicide. Although previous work has demonstrated that deployment is not associated with suicide overall in this population, there is growing evidence that risk may be elevated shortly after deployment, and for some subgroups. Specific aspects of combat exposure, including the experience of killing or witnessing death in combat, may be important contributing factors. An analysis of the literature illustrates that deployment-related risk factors for suicide are complex. The limitations of the literature are discussed, and future directions are suggested. PMID- 30286300 TI - Changes in exercise capacity and serum BDNF following long-term sprint interval training in well-trained cyclists. AB - The study determined the effects of sprint interval training on the acute and chronic changes of serum brain-derived neurotrophic factor (BDNF) and aerobic capacity. Twenty-six cyclists were divided into experimental (E) and control (C) group. Both groups executed 6-month exercise intervention involving high intensity interval training (HIIT) and continuous endurance training (CET) with group E replacing HIIT and CET sessions with sprint interval training (SIT) executed twice a week. Two exercise tests were administered prior to the intervention and 2 and 6 months after study outset. Incremental exercise test (IXT) assessed aerobic capacity by measuring maximal oxygen uptake (VO2max) and work output, and sprint interval exercise test (SIXT; three sets of four 30-s all out repetitions interspersed with 90 s of rest with sets separated by 25-40 min active recovery). Oxygen uptake, work output, BDNF and vascular endothelial growth factor A (VEGF-A) concentrations (baseline, 10 min after first set and 10 and 60 min after third SIXT set), were taken during the sprint interval exercise test. Significant decreases in BDNF relative to baseline values were observed 10 min after first set and 60 min after third set in group E at the 2- and 6-month assessments. Increases baseline VEGF-A after 2 and 6 months of training and increase VO2max after 2 months of training was also observed only in group E. The inclusion of SIT with HIIT and CET shows positive long-term effects including increased VO2max and baseline VEGF-A and reduction BDNF below baseline levels during and after SIXT.

AB - OBJECTIVES:: In 2005, Hurricane Katrina caused damage in New Orleans, Louisiana, and much of the land in low-resource neighborhoods became vacant and blighted. In 2014, New Orleans launched a program, Fight the Blight, which remediated properties in 6 neighborhoods. Our objective was to examine changes in crime rates near lots that were remediated (ie, debris removed and vegetation mowed). METHODS:: We used a quasi-experimental design to test whether crime rates changed from preremediation (January 2013-October 2014) to postremediation (July 2016 March 2017) near 204 vacant lots that were remediated compared with 560 control vacant lots that were not remediated between October 2014 and July 2016. We also examined differences between remediated lots that received 1 treatment (n = 64) and those that received >=2 treatments (n = 140). RESULTS:: We found no significant differences between remediated and control lots in levels of violent, property, and domestic crimes from preremediation to postremediation. However, the number of drug crimes per square mile decreased significantly near all remediated lots (5.7% lower; P < .001) compared with control lots, largely driven by the significant decrease (6.4% lower; P < .001) in drug crimes found near lots that received >=2 treatments. CONCLUSIONS:: Investing in programs that improve neighborhood environments affected by high rates of physical disorder and vacancy may be a way to decrease violence. However, routine remediation may be needed to increase the public health impact of blight abatement programs in warmer climates, where weeds and vegetation grow rapidly. PMID- 30286301 TI - Integrating a nationally scaled workforce of community health workers in primary care: a modelling study. AB - Objective To model cost and benefit of a national community health worker workforce. Design Modelling exercise based on all general practices in England. Setting United Kingdom National Health Service Primary Care. Participants Not applicable. Data sources Publicly available data on general practice demographics, population density, household size, salary scales and screening and immunisation uptake. Main outcome measures We estimated numbers of community health workers needed, anticipated workload and likely benefits to patients. Results Conservative modelling suggests that 110,585 community health workers would be needed to cover the general practice registered population in England, costing L2.22bn annually. Assuming community health workerss could engage with and successfully refer 20% of eligible unscreened or unimmunised individuals, an additional 753,592 cervical cancer screenings, 365,166 breast cancer screenings and 482,924 bowel cancer screenings could be expected within respective review periods. A total of 16,398 additional children annually could receive their MMR1 at 12 months and 24,716 their MMR2 at five years of age. Community health workerss would also provide home-based health promotion and lifestyle support to patients with chronic disease. Conclusion A scaled community health worker workforce integrated into primary care may be a valuable policy alternative. Pilot studies are required to establish feasibility and impact in NHS primary care.

AB - To verify the association between anthropometric indicators and body fat percentage (F %) estimated by dual X-ray absorptiometry (DXA) and air displacement plethysmography (ADP) in children and adolescents diagnosed with HIV. This cross-sectional study was carried out with 62 children and adolescents with HIV (8 to 15 years). F % was estimated by DXA and ADP. Anthropometric indicators were skinfolds (abdominal, triceps, subscapular, calf); perimeter relaxed arm (PRA), waist circumference (WC), perimeter neck (PN); body mass index (BMI); waist-to-height ratio (WHR); conicity index and body adiposity index. Linear regressions were performed with 5% significance level. In boys (R2adj = 0.38 to R2adj = 0.67) and girls (R2adj = 0.41 to R2adj = 0.57), all anthropometric indicators were associated with F% estimated by DXA. For boys, skinfolds were associated with F % estimated by ADP (R2adj = 0.18 to R2adj = 0.35). In girls, skinfolds (R2adj = 0.27 to R2adj = 0.44, BMI (R2adj = 0.31), PRA (R2adj = 0.36) and WC (R2adj = 0.26) were associated to F % by ADP. Abdominal skinfold was the indicator that most explained the variation in F % measured by DXA and ADP in both sexes. Anthropometric indicators are strongly associated with body fat, measured by reference methods, and can assist health professionals in monitoring the health of children and adolescents with HIV. PMID- 30286303 TI - The effect of multiple micronutrient fortified milk consumption on vitamin D status among school-age children in rural region of Morocco. AB - Vitamin D deficiency is a health problem in both developed and developing countries. The aim of this study was to determine the effect of multivitamin fortified milk consumption on vitamin D status among children living in the mountainous region of Morocco. 7 to 9 years old children (n=239; 49% of girls vs 51% of boys) have participated in a double blind longitudinal study, where they were divided in two groups: a fortified group who received daily 200 mL of fortified Ultra-High Temperature (UHT) milk enriched with 3MUg of vitamin D3 and a non-fortified group who received 200 mL of non-fortified UHT milk with a natural abundance of vitamin D3 (about 1.5ug). Blood samples were collected three times (at baseline, after 4 and 9 months). The average weight, height and BAZ of participants were 22.8+/-2.6 kg, 121.5+/-5.2 cm and -0.2+/-0.6 kg/m2 respectively. At baseline, 47.5% of children had a concentration of 25 hydroxyvitamin D (25(OH)D) below 50 nmol/L. At the end of the study the prevalence of vitamin D <50 nmol/L decreased significantly by 37.6 % in the fortified group. These results reveal prevalent vitamin D insufficiency (<50 nmol/L) during winter among rural Moroccan school age children, which seems to be better improved by consuming the fortified milk instead of non-fortified one. PMID- 30286304 TI - Adolescents with autism show typical fMRI repetition suppression, but atypical surprise response. AB - Recent theoretical frameworks have hypothesized that autism spectrum disorder (ASD) may be marked by an altered balance between sensory inputs and prior knowledge-the so-called hypoprior hypothesis. Yet evidence regarding such an altered balance is mixed. Here, we aimed to test this hypothesis within the domain of visual perception, by examining how neural activity in the visual system was modulated by stimulus repetition and stimulus expectation in healthy and ASD participants. We presented 22 adolescents with ASD and 22 typically developing (TD) adolescents with pairs of object stimuli, while measuring brain activity using functional magnetic resonance imaging (fMRI). Stimulus pairs could be stimulus repetitions or not and could be expected or not. We examined neural activity in early (V1) and object-selective (LOC) visual cortex. Both ASD and TD individuals showed robust and equal repetition suppression in LOC. By contrast, ASD and TD groups showed a different response to expected versus unexpected stimuli, specifically in V1. Thereby, our results suggest that while the more automatic modulation of activity by repetition is unaffected in ASD, there is some evidence that the balance between sensory evidence and prior knowledge may indeed be altered in early visual cortex of ASD. PMID- 30286305 TI - One versus two eyes makes a difference! Early face perception is modulated by featural fixation and feature context. AB - The N170 event-related potential component is an early marker of face perception that is particularly sensitive to isolated eye regions and to eye fixations within a face. Here, this eye sensitivity was tested further by measuring the N170 to isolated facial features and to the same features fixated within a face, using a gaze-contingent procedure. The neural response to single isolated eyes and eye regions (two eyes) was also compared. Pixel intensity and contrast were controlled at the global (image) and local (featural) levels. Consistent with previous findings, larger N170 amplitudes were elicited when the left or right eye was fixated within a face, compared to the mouth or nose, demonstrating that the N170 eye sensitivity reflects higher-order perceptual processes and not merely low-level perceptual effects. The N170 was also largest and most delayed for isolated features, compared to equivalent fixations within a face. Specifically, mouth fixation yielded the largest amplitude difference, and nose fixation yielded the largest latency difference between these two contexts, suggesting the N170 may reflect a complex interplay between holistic and featural processes. Critically, eye regions elicited consistently larger and shorter N170 responses compared to single eyes, with enhanced responses for contralateral eye content, irrespective of eye or nasion fixation. These results confirm the importance of the eyes in early face perception, and provide novel evidence of an increased sensitivity to the presence of two symmetric eyes compared to only one eye, consistent with a neural eye region detector rather than an eye detector per se. PMID- 30286306 TI - Changes in acceptance of dating violence and physical dating violence victimization in a longitudinal study with teens. AB - Teen dating violence is a pervasive issue in adolescence and has been linked to maladjustment (Temple, Shorey, Fite et al., 2013). Physical dating violence is a particularly significant problem with one in five adolescents reporting experiencing physical teen dating violence (TDV; Wincentak et al., 2017). Acceptance of violence has been suggested to increase the risk of TDV; however, most studies to date have been cross-sectional. The purpose of the current study is to examine patterns of acceptance of dating violence and TDV victimization across time. Participants were ethnically diverse teenagers (N = 1042; ages 13 18) who were followed over a four-year period. Multivariate latent growth curve modeling techniques were used to determine trajectories of physical TDV victimization and attitudes accepting of dating violence. Results showed two trajectories for physical TDV victimization, linear and quadratic, and two trajectories for acceptance of dating violence, non-linear and quadratic. Parallel models investigating the interplay between TDV victimization and acceptance demonstrated two possible trends; however, we did not find any evidence for a longitudinal relationship between the two variables, suggesting that change in acceptance was not related to change in physical TDV victimization. Instead, our results suggest a significant amount of heterogeneity in these trajectories. These findings suggest studies are still needed to further explore longitudinal patterns of TDV to better understand how to reduce the risk of teen dating violence. PMID- 30286307 TI - A universal method to create surface patterns with extreme wettability on metal substrates. AB - Extreme wettability surfaces have attracted more and more attention due to their practical applications, however, few reports have shown a universal method to create surface patterns with extreme wettability on a variety of metals. In this paper, a mask-assisted dual-chemical-processing approach without special modification is used to prepare the extreme wettability patterns on various metal substrates. Fabrication of superhydrophilic-superhydrophobic patterns on five kinds of metal substrates of Al, Ti, steel, Zn and Mg alloy proved the versatility of this method. The extreme wettability patterns prepared by this method were applied to fog harvest and we found the big differences in the collection efficiency of various metal surface patterns. PMID- 30286308 TI - Self-cleaning, stain-resistant and anti-bacterial superhydrophobic cotton fabric prepared by simple immersion technique. AB - In this paper, superhydrophobicity of cotton fabric was produced by simple immersion method in non-fluorinated hexadecyltrimethoxysilane solution. Modified cotton fabric showed repellency to water and liquids with surface tension of more than 47 mN/m, with a static contact angle of more than 150 degrees and tilt angle of less than 10 degrees . The mechanical, chemical, thermal, and UV stability of superhydrophobic cotton fabric was evaluated. Modified cotton fabric exhibited the self-cleaning and stain-resistant properties. It also showed that it could be used for oil-water separation application with separation efficiency of about 99%. Additionally, the modified cotton fabric exhibited anti-bacterial properties. This approach is facile, economical, and eco-friendly and can be applied for household and industrial applications. PMID- 30286309 TI - Datura-like Ni-HG-rGO as highly efficient electrocatalyst for hydrogen evolution reaction in alkaline conditions. AB - Development of highly-active and noble-metal-free electrocatalysts for hydrogen evolution reactions is a challenge, and optimizing the structure and the composition of the relative materials is critical to obtain the high-quality catalysts. Ni-based compounds are being explored as noble-metal-free electrocatalysts in hydrogen evolution reactions but the Ni-based needs to be modified effectively. In this work, we co-electrodeposited Ni nanoparticles, hydrophilic graphene and graphene oxide layers on Ni foam to synthesize Ni-HG rGO/NF catalysts. It was presented a Datura-like shape allowing for high performance with current densities of -10 and -100 mA cm-2 for HER at overpotentials of -50 and -132 mV, a low Tafel slope of -48 mV dec-1 and excellent long-term stability in 1.0 M NaOH solution. These results demonstrate that the Ni-HG-rGO/NF electrode can be a competitive electrode materials for HER in alkaline conditions. PMID- 30286310 TI - Carrier-free core-shell nanodrugs for synergistic two-photon photodynamic therapy of cervical cancer. AB - Carrier-free nanodrugs named BCNPs were prepared by the coassembly of 2,5-bis(4 (diethylamino)benzylidene)cyclopentanone (BDBC) and curcumin (CCM) in the absence of surfactants. The as-synthesized BCNPs possess high dispersity and stability in aqueous media, along with favorable photostability and good biocompatibility. Comparing with their counterparts BDBC and CCM, BCNPs exhibit higher singlet oxygen yield and better two-photon photodynamic therapy (PDT) efficacy. Moreover, BCNPs display dramatically enhanced ability for inhibiting the growth of HeLa cells, which benefits from the synergistic treatment of BDBC and CCM under the irradiation of 450/808 nm. This work highlights the potential of using simple coassembly strategy to codelivery of multiple drugs in one single formulation for cancer therapy. PMID- 30286311 TI - Salt and water co-assisted exfoliation of graphite in organic solvent for efficient and large scale production of high-quality graphene. AB - Graphene has attracted enormous attention due to its unique physical properties and attractive applications in many fields. However, it is an ongoing challenge to develop a facile and low-cost method for the large scale preparation of high quality graphene (HQGr). In this work, we have developed an improved liquid-phase exfoliation method to mass produce HQGr. This method is quite simple but efficient by exfoliation of graphite in organic solvent with the co-assistance of sodium citrate and water. Remarkably, the concentration of as-exfoliated HQGr was as high as 0.71 mg/mL under optimal conditions, while the oxygen content in HQGr was only 2.39%. After annealing at 500 degrees C for 2 h in argon atmosphere, the mean conductivity of annealed HQGr was as high as 1.4 * 104 S m-1. Therefore, this facile method for liquid-phase exfoliation of graphite has excellent potential in the industrial-scale production of HQGr for numerous applications in energy storage, optical and electronic fields. PMID- 30286312 TI - Assessment of quiet T2 weighted PROPELLER sequence in pediatric abdominal imaging. AB - INTRODUCTION: Elevated acoustic noise during Magnetic Resonance Imaging (MRI) has been associated with patient anxiety and altered cochlear function. Acoustic Reduction Technique (ART) T2 weighted (T2w) periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) has been studied in brain MR but not abdominopelvic imaging. The purpose of our study was to evaluate the image quality and acoustic noise level of ART T2w PROPELLER sequence in comparison with the conventional T2w PROPELLER sequence in pediatric abdomino pelvic imaging. METHODS: Eleven consecutive pediatric patients undergoing abdomino-pelvic MRI were scanned on a 3 Tesla magnet using standard and ART T2w PROPELLER sequences. After scanning completion, objective sound level measurements were performed with a sound level meter and microphone. Mann-Whitney U test was used for a non-parametric two-tailed statistical analysis of acoustics, image rating and scan time with significance level set to 0.05. Overall inter-rater agreement was calculated using Cohen's kappa coefficient. RESULTS: Eleven pediatric patients (4 females and 7 males) between 26 days and 18 years of age (mean = 10.0, SD = 5.8) were included. ART T2w produced lower levels of acoustic noise than standard technique in a comparison of mean decibel readings from eleven trials of standard and ART T2w (p value = 0.00008). Streak artifacts were rated greater in ART T2w by both raters (p-value = 0.00278 and 0.00252). There was no significant difference in bile duct blurring, respiratory ghosting, pulsation, fat suppression or hepatic parenchymal depiction. CONCLUSION: Presence of additional streaking artifacts should be considered along with the benefit of reduced acoustic noise from ART T2w. PMID- 30286313 TI - Diffusion tensor imaging and quantitative susceptibility mapping as diagnostic tools for motor neuron disorders. AB - PURPOSE: Diffusion tensor imaging (DTI) and quantitative susceptibility mapping (QSM) have been proposed as methods to aid in the diagnosis of amyotrophic lateral sclerosis (ALS) and primary lateral sclerosis (PLS), both diseases affecting upper motor neurons. We test the performance of DTI and QSM alone and in combination to distinguish patients with diseases affecting upper motor neurons (ALS/PLS) from patients with other motor symptom-predominant neurologic disorders. METHODS: 3.0 Tesla MRI with DTI and QSM in patients referred to a subspecialty neurology clinic for evaluation of motor symptom-predominant neurologic disorders were retrospectively reviewed. Corticospinal tract fractional anisotropy and maximum motor cortex susceptibility were measured. Subjects were categorized by diagnosis and imaging metrics were compared between groups using Student's t-tests. Receiver operating characteristic curves were generated for imaging metrics alone and in combination. RESULTS: MRI scans for 43 patients with ALS or PLS and 15 patients with motor symptom predominant, non upper motor neuron disease (mimics) were reviewed. Fractional anisotropy was lower (0.57 vs. 0.60, p < 0.01) and maximum motor cortex magnetic susceptibility higher (64.4 vs. 52.7, p = 0.01) in patients with ALS/PLS compared to mimics. There was no significant difference in area under the curve for these metrics alone (0.73, 0.63; p > 0.05) or in combination (0.75; p > 0.05). CONCLUSION: We found significant differences in DTI and QSM metrics in patients with diseases affecting upper motor neurons (ALS/PLS) compared to mimics, but no significant difference in the performance of these metrics in diagnosing ALS/PLS compared to mimics. PMID- 30286314 TI - Functional movement disorders of the face: A historical review and case series. AB - Functional facial dystonia or spasm has, in recent years, been recognised as a relatively common form of functional movement disorder. We describe historical 'forgotten' neurological literature indicating that this was a well described phenomenon in the late 19th and early 20th century but subsequently faded from awareness. We add data from our own series of 41 patients with functional facial dystonia to explore the clinical features and associated comorbidities of patients with this movement disorder. PMID- 30286315 TI - Dietary patterns and colorectal cancer risk in Zimbabwe: A population based case control study. AB - BACKGROUND: The rising incidence of colorectal cancer in sub-Saharan Africa may be partly caused by changing dietary patterns. We sought to establish the association between dietary patterns and colorectal cancer in Zimbabwe. METHODS: One hundred colorectal cancer cases and 200 community-based controls were recruited. Data were collected using a food frequency questionnaire, and dietary patterns derived by principal component analysis. Generalised linear and logistic regression models were used to assess the associations between dietary patterns, participant characteristics and colorectal cancer. RESULTS: Three main dietary patterns were identified: traditional African, urbanised and processed food. The traditional African diet appeared protective against colorectal cancer (Odds Ratio (OR) 0.35; 95% Confidence Interval (CI), 0.21 - 0.58), which had no association with the urban (OR 0.68; 95% CI, 0.43-1.08), or processed food (OR 0.91; 0.58-1.41) patterns. The traditional African diet was associated with rural domicile, (OR 1.26; 95% CI, 1.00-1.59), and a low income (OR1.48; 95% CI, 1.06 2.08). The urbanised diet was associated with urban domicile (OR 1.70; 95% CI, 1.38-2.10), secondary (OR 1.30; 95% CI, 1.07-1.59) or tertiary education (OR 1.48; 95% CI, 1.11-1.97), and monthly incomes of $201-500 (OR 1.30; 95% CI, 1.05 1.62), and the processed food pattern with tertiary education (OR 1.42; 95% CI, 1.05-1.92), and income >$1000/month (OR 1.48; 95% CI, 1.02-2.15). CONCLUSION: A shift away from protective, traditional African dietary patterns may partly explain the rising incidence of colorectal cancer in sub-Saharan Africa. PMID- 30286316 TI - Body weight support through a walking cane in inexperienced users with knee osteoarthritis. AB - BACKGROUND: Walking canes are a self-management strategy recommended for people with knee osteoarthritis (OA) by clinical practice guidelines. Ensuring that an adequate amount of body-weight support (%BWS) is taken through the walking cane is important as this reduces measures of knee joint loading. RESEARCH QUESTION: 1) How much body weight support do people with knee OA place through a cane? 2) Do measures of body weight support increase following a brief simple training session? METHODS: Seventeen individuals with knee pain who had not used a walking cane before were recruited. A standard-grip aluminum cane was then used for 1 week with limited manufacturer instructions. Following this, participants were evaluated using an instrumented force-measuring cane to assess body weight support (% total body weight) through the cane. Force data were recorded during a 430-metre walk undertaken twice; once before 10 min of cane training administered by a physiotherapist, and once immediately after training. Measures of BWS (peak force, average force, impulse equal to the average cane force times duration, and cane-ground contact duration) were extracted. Using bathroom scales, training aimed to take at least 10% body weight support through the cane. RESULTS: Before training, the average peak BWS was 7.2 +/- 2.5% of total body weight. Following 10 min of training, there was a significant increase in average peak BWS by 28%, average BWS by 25%, and BWS impulse by 54% (p < 0.05). However, individual BWS responses to training were variable. Duration of cane placement increased by 22% after training (p = 0.02). Timing of peak BWS through the cane occurred at 51% of contact phase before training, and at 53% after training (p = 0.05). SIGNIFICANCE: A short training session can increase the transfer of body weight through a walking cane. However, more sophisticated feedback may be needed to achieve target levels of BWS. PMID- 30286317 TI - Changes in the symmetry of external perturbations affect patterns of muscle activity during gait initiation. AB - BACKGROUND: Gait initiation is associated with changes in the steady state and experiencing an external perturbation during initiation of gait could further threaten balance stability. RESEARCH QUESTION: The aim of the study was to investigate if changes in the symmetry of the perturbations affect patterns of muscle activity during gait initiation. METHODS: Eleven young health participants were instructed to stand on the force platform and wait for the instruction of taking a right step, left step or stand still while experiencing a pendulum perturbation applied to the back of both shoulders (symmetric), back of the right shoulder (asymmetric) or no perturbations. Bilateral electromyographic activity (EMG) of dorsal and ventral muscles, moments of the pendulum release and perturbation impact, center of pressure (COP) displacements and pelvic movements were recorded and analyzed before and after the onset of the perturbation. RESULTS: Taking the right/left step in presence of symmetric perturbation did not affect the temporal sequence of COP and pelvic movements. The onset of COP and pelvic movement occurred before the perturbation impact at the shoulder levels. The factors of step and perturbation did not significantly affect integrals of bilateral muscles at the pendulum release. After the pendulum release, ventral and dorsal EMG integrals of the trunk, thigh, and shank segments increased or decreased corresponding to the swing and stance leg. Changes in muscle activities were also associated with the symmetric or asymmetric perturbations before and after the perturbation impact. SIGNIFICANCE: The outcome of the study provides information about strategies used to coordinate the activity of muscles while body perturbations are induced during gait initiation. PMID- 30286318 TI - Endosymbiosis-related changes in ultrastructure and chemical composition of Chlorella variabilis (Archaeplastida, Chlorophyta) cell wall in Paramecium bursaria (Ciliophora, Oligohymenophorea). AB - Chlorella variabilis, a symbiotic alga, is usually present in the cytoplasm of Paramecium bursaria, although it can be cultured in host-free conditions. Morphological and chemical properties of its cell wall were compared between its free-living and symbiotic states. Transmission electron microscopy (quick freezing and freeze-substitution methods) revealed that the cell wall thickness of symbiotic C. variabilis was reduced to about half that of the free-living one. Chemical properties of the cell wall were examined by treatment with three fluorescent reagents (calcofluor white M2R, FITC-WGA, and FITC-LFA) having specific binding affinities to different polysaccharides. When the algae were re introduced into Paramecium host cells, calcofluor fluorescence intensity reduced by about 50%. Calcofluor stains beta-d-glucopyranose polysaccharides such as cellulose, N-acetylglucosamine, sialic acid, and glycosaminoglycans. Because treatment with cellulase showed no effect on calcofluor fluorescence intensity, we consider that cellulose is not majorly responsible for the stainability of calcofluor. Staining intensities of FITC-WGA and FITC-LFA were similar in the free-living and symbiotic conditions, suggesting that N-acetylglucosamine and sialic acid are also not responsible for the reduction in the stainability of calcofluor associated with intracellular symbiosis. The amount of glycosaminoglycans on the cell wall may decrease in C. variabilis present in the cytoplasm of P. bursaria. PMID- 30286319 TI - Modulating the interhemispheric balance in healthy participants with transcranial direct current stimulation: No significant effects on word or sentence processing. AB - Patient studies and brain stimulation evidence suggest that language processing can be enhanced by altering the interhemispheric balance: namely, preferentially enhancing left-hemisphere activity while suppressing right-hemisphere activity. To our knowledge, no study has yet compared the effects of such bilateral brain stimulation to both logically necessary control conditions (separate left- and right-hemisphere stimulation). This study did so in a between-group sham controlled design, applying transcranial direct current stimulation over Broca's area and/or its homologue in 72 healthy participants. The effects were measured not only in a single-word-level task but also in a sentence-level task, rarely tested previously. We did not find either any significant overall effects of stimulation or greater stimulation effects in the bilateral compared to control groups. This null result, obtained in a large sample, contributes to the debate on whether tDCS can modulate language processing in healthy individuals. PMID- 30286320 TI - Immunomodulatory injectable silk hydrogels maintaining functional islets and promoting anti-inflammatory M2 macrophage polarization. AB - Islet transplantation is considered the most promising treatment for type 1 diabetes. However, the clinical success is limited by islet dysfunction in long term culture. In this study, we have utilized the rapid self-gelation and injectability offered by blending of mulberry silk (Bombyx mori) with non mulberry (Antheraea assama) silk, resulting in a biomimetic hydrogel. Unlike the previously reported silk gelation techniques, the differences in amino acid sequences of the two silk varieties result in accelerated gelation without requiring any external stimulus. Gelation study and rheological assessment depicts tuneable gelation as a function of protein concentration and blending ratio with minimum gelation time. In vitro biological results reveal that the blended hydrogels provide an ideal 3D matrix for primary rat islets. Also, A. assama fibroin with inherent Arg-Gly-Asp (RGD) shows significant influence on islet viability, insulin secretion and endothelial cell maintenance. Furthermore, utility of these hydrogels demonstrate sustained release of Interleukin-4 (IL-4) and Dexamethasone with effective M2 macrophage polarization while preserving islet physiology. The immuno-informed hydrogel demonstrates local modulation of inflammatory responses in vivo. Altogether, the results exhibit promising attributes of injectable silk hydrogel and the utility of non-mulberry silk fibroin as an alternative biomaterial for islet encapsulation. PMID- 30286321 TI - In silico screening of cancer-associated mutations in the HSA domain of BRG1 and its role in affecting the Arp-HSA sub-complex of SWI/SNF. AB - SWI/SNF (SWItch/Sucrose Non-Fermentable) complexes regulate the gene expression programs by remodeling the nucleosome architecture of the chromatin functional elements. These large multi-component complexes comprise eight or more subunits and are conserved from yeast to human. Noticeably, nuclear actin and actin related proteins (Arps) are an integral part of these complexes and are known to directly interact with the helicase-SANT-associated (HSA) domain of ATPase subunit. Recently, SWI/SNF subunits are gaining importance because of the prevalence of cancer-causing mutations associated with them. The functional characterization of the mutations in the SWI/SNF subunits is important for understanding their role in tumorigenesis and identifying potential therapeutic strategies. To study the actin-related complex of human SWI/SNF and the cancer associated mutations interfering Arp assembly with the ATPase subunit, we modelled the structure of the beta-actin-BAF53A-HSA complex based on the yeast Arp-HSA complex (PDB ID: 4I6M). Seven deleterious mutations in the HSA domain of BRG1 were identified based on the functional screening of cancer-associated mutations in the COSMIC database. Detailed structural analysis of the six mutations (R466H, R469W, Y489C, K502N, R513Q and R521P) based on molecular dynamics (MD) simulations reveal the distinct effect of each mutation in destabilizing the structure of the Arp-HSA complex. Predominantly we could notice the long-range effect of the HSA mutations in influencing the dynamics of the Arp subunits. PMID- 30286322 TI - In silico analysis of Pax6 protein glycosylation in vertebrates. AB - Pax6 is a transcription factor that involves in the formation of the eye, brain, and central nervous system in vertebrates. Due to various roles in the eye morphogenesis, Pax6 interacts with DNA and various transcription factors via post translational modifications. Post-translational modifications of Pax6 have been studied extensively but there is a paucity of information about the glycosylation. Here, we focused on predicting the glycosylation positions of Pax6 protein in vertebrates. Also, 3D protein and glycoprotein models were generated using I-TASSER and GLYCAM servers in order to understand the effect of glycosylation on the Pax6 protein structure. We predicted N-glycosylation, mucin type O-glycosylation, O-alpha-GlcNAcylation, and O-beta-GlcNAcylation positions on Pax6 protein besides O-GlcNAc modification. Moreover, we found ying-yang positions suggesting the presence of O-GlcNAcylation/phosphorylation competition in Pax6. As to 3D glycoprotein models of Pax6, Ser24, Ser65, and Ser74 residues at the PD domain of Pax6 protein was evaluated as a strong candidate for the DNA binding site. We suggest that determination of the glycosylation positions on 3D glycoprotein model will facilitate the understanding of glycosylation role on Pax6 protein interactions in transcription and intracellular activities.

AB - Cold stress response is mediated by multiple signaling pathways with complex interactions, among which phytohormones may play a role. We explored changes in the contents of phytohormones, including abscisic acid, jasmonic acid, salicylic acid, auxin, cytokinins, gibberellins and melatonin, along with stress tolerance markers in an invasive halophyte, Carpobrotus edulis in response to chilling. In a first experiment, plants were exposed to mean daily temperatures from 10 degrees C to 5 degrees C during a cold wave in an experimental garden. In a second experiment, plants were subject to slowly decreasing temperatures, from 20 to 5 degrees C, in a climatic chamber. Although the cold response in both experiments was associated with a similar extent of leaf desiccation, hormonal variations differed. Cold stress reduced melatonin contents, while it increased salicylic acid contents in the experimental garden. Rather, transient increases in the contents of melatonin occurred in parallel with sustained increases in the contents of abscisic acid and cytokinins in the climatic chamber. In both experiments, plants were able to prevent cold-induced increases in lipid peroxidation and any eventual damage to the photosynthetic apparatus. We conclude that (i) the hormonal response to chilling in C. edulis is strongly dependent on time exposure to low temperatures, severity of stress, as well as other environmental conditions, (ii) the hormonal response of this plant species to low temperatures is very plastic, thus underlining its great capacity for cold acclimation. PMID- 30286324 TI - Proteome of olive non-glandular trichomes reveals protective protein network against (a)biotic challenge. AB - Olive is one of the most important fruit crop trees in the history of Mediterranean because of the high quality oil. Olive oil has a well-balanced fatty acid composition along with biophenols, which make it exceptional in human diet and provide an exceptional value to the olive oil. Leaf non-glandular peltate trichomes are specialized cell types representing a protective barrier against acute environmental conditions. To characterize the proteome of this highly differentiated cell type, we performed a comparative proteomic analysis among isolated trichomes and trichome-less leaves. Proteins were separated and identified using the 2-DE MALDI-TOF/MS method. A number of enzymes involved in abiotic and biotic stress responses are present and may be responsible for the adaptation to prolonged adverse environmental conditions. The results show that this highly differentiated cell type is physiologically active fulfilling the demands of the trichomes in furnishing the leaf with a highly protective mechanism. PMID- 30286325 TI - Neurometabolic abnormalities in the associative striatum in antipsychotic-naive first episode psychosis patients. AB - Schizophrenia is a chronic, often progressive, disorder. Understanding the underlying neurobiology present in the early stages of the illness is as a pivotal step in designing targeted interventions aimed at arresting disease progression. The aim of our study was to examine neurometabolic changes in the dopamine rich associative striatum in medication-naive first episode psychosis (FEP). We quantified neurometabolites in 14 FEP and 18 healthy controls (HC) matched on key demographic characteristics. Spectra from the voxel in the left associative striatum were acquired using a PRESS sequence (TR/TE = 2000/80 ms; 512 averages). MRS data were quantified in the time domain with AMARES in jMRUI. Choline was significantly elevated in FEP compared to HC. No significant alterations in other metabolites were observed. We did not observe correlations between metabolite levels and clinical characteristics in FEP. Here, we demonstrated elevated choline and a disruption of the relationship between N acetyl-aspartate and Glx (glutamate + glutamine) in medication-naive FEP patients in the left striatum indicating possible mitochondrial, membrane and glial dysfunction as an underlying pathological phenomenon. In addition, striatal choline shows promise as a biomarker for FEP that may have utility in clinical trials investigating target engagement in experimental regimens. PMID- 30286327 TI - Expression of the Annexin A1 and its correlation with matrix metalloproteinases and the receptor for formylated peptide-2 in diffuse astrocytic tumors. AB - Astrocytomas represent the majority of cerebral gliomas. Studies show that the anti-inflammatory protein Annexin-A1 (ANXA1) is associated with the tumor invasion process and that its actions can be mediated by the receptor for formylated peptides (FPR). Therefore, we evaluated the expression of ANXA1, the receptor FPR2 and matrix metalloproteinases 2 and 9 (MMP-2 and MMP-9) in brain astrocytomas. Detection of proteins was performed in sections of diffuse astrocytomas (grade II), anaplastic astrocytomas (grade III) and glioblastomas (GBM, grade IV) and quantifications were made by densitometry. Our analyses showed increased expression of ANXA1 in astrocytomas of all grades, but especially in GBM. The expression of FPR2 is similar to that found for ANXA1, being higher in GBM. Immunostaining for MMPs is also stronger as the degree of malignancy increases, especially with respect to MMP-9. The positive correlation between ANXA1/FPR2 and ANXA1/MMP-9 was observed in all tumors studied. The data indicate the possible action of ANXA1 and FPR2 on the development and progression of astrocytomas, related to increased expression of MMP-9. Thereby, ANXA1 and FPR2 are involved in the biology and malignancy of diffuse astrocytic tumors. PMID- 30286326 TI - Investigation of PP2A and Its Endogenous Inhibitors in Neuroblastoma Cell Survival and Tumor Growth. AB - High-risk neuroblastoma continues to carry a poor prognosis. Nearly 50% of these tumors relapse following extensive treatment regimens. Protein phosphatase 2A (PP2A), a tumor suppressor, has been shown to be downregulated in many human cancers via multiple mechanisms including upregulation of its endogenous inhibitors, I2PP2A or CIP2A. We hypothesized that inhibition of the endogenous PP2A inhibitors or activation of PP2A would decrease tumorigenicity in human neuroblastoma cells. Four human neuroblastoma cell lines were utilized. Expression of PP2A and its endogenous inhibitors I2PP2A and CIP2A was confirmed by immunoblotting. PP2A activation was measured via phosphatase activation assay. Multiple parallel methods including siRNA inhibition of the endogenous PP2A inhibitors and pharmacologic activation of PP2A were utilized. Cell viability, proliferation, migration, and invasion assays were performed. In vivo studies were utilized to determine the effects of PP2A activation on neuroblastoma tumor growth. Inhibition of the endogenous inhibitors of PP2A or pharmacologic activation of PP2A with the PP2A activator FTY720 led to decreased neuroblastoma cell viability, proliferation, migration, and invasion. Treatment of mice bearing SK-N-AS or SK-N-BE(2) neuroblastoma tumors with FTY720 resulted in a significant decrease in tumor growth compared to vehicle-treated animals. In conclusion, activation of PP2A may provide a novel therapeutic target for neuroblastoma. PMID- 30286328 TI - Exploratory analysis of mediators of the relationship between childhood maltreatment and suicidal behavior. AB - INTRODUCTION: Suicide is a major public health concern. One consistently cited risk factor for suicide is childhood maltreatment, which also may play a role in the transition from suicidal ideation to suicidal behavior. METHOD: The current study aimed to examine the relationship between childhood maltreatment and suicide attempts during adolescence (N = 4834; 52.1% female; 67.5% Caucasian). Data from the U.S. National Longitudinal Study of Adolescent Health were utilized. Forty-six theoretically-relevant risk factors were explored as potential mediators of this relationship using an exploratory mediation data analytic method. RESULTS: Results demonstrated a significant childhood maltreatment - suicide attempt relationship only among females. After considering demographics and suicidal ideation, having received counseling in the previous 12 months was the most influential mediator, followed by having a friend attempt suicide in the previous 12 months. CONCLUSIONS: These findings highlight potential gender differences in the relationship between childhood maltreatment and later suicide attempts, and, moreover, the importance of assessing for recent exposure to peer suicidal behavior in suicide risk assessments. PMID- 30286329 TI - Brief report: A qualitative evidence synthesis of the psychological processes of school-based expressive writing interventions with adolescents. AB - INTRODUCTION: Expressive writing interventions consist of brief writing sessions on thoughts and emotions and are known to yield positive benefits on adolescents' mental health. However, the psychological mechanisms explaining these effects are not clear. METHOD: This review explored the psychological processes underlying school-based expressive writing interventions with adolescents. A thematic synthesis of qualitative research consisted of identifying, appraising and summarizing the qualitative evidence of eligible studies. RESULTS: Only six of the 510 identified studies met the inclusion criteria of this review. Results provide some validation for cognitive-processing, emotion-regulation, and disinhibition as psychological mechanisms underlying school-based expressive writing with adolescents. CONCLUSIONS: However, these conclusions are still preliminary because of the paucity of the qualitative evidence found, both in quantity and quality. We recommend that more rigorous and in-depth qualitative research be undertaken to: 1) explore adolescents' subjective experience about the expressive writing intervention, using in-depth individual interviews; 2) thoroughly assess the content of students' texts written during the intervention; and 3) document the process of expressive writing interventions through observational methods. The results of such investigations would support the development and implementation of school-based expressive writing-type of interventions adapted to adolescents. PMID- 30286330 TI - Iron overload in myelodysplastic syndromes: Evidence based guidelines from the Canadian consortium on MDS. AB - In 2008 the first evidence-based Canadian consensus guideline addressing the diagnosis, monitoring and management of transfusional iron overload in patients with myelodysplastic syndromes (MDS) was published. The Canadian Consortium on MDS, comprised of hematologists from across Canada with a clinical and academic interest in MDS, reconvened to update these guidelines. A literature search was updated in 2017; topics reviewed include mechanisms of iron overload induced cellular damage, evidence for clinical endpoints impacted by iron overload including organ dysfunction, infections, marrow failure, overall survival, acute myeloid leukemia progression, and endpoints around hematopoietic stem-cell transplant. Evidence for an impact of iron reduction on the same endpoints is discussed, guidelines are updated, and areas identified where evidence is suboptimal. The guidelines address common questions around the diagnosis, workup and management of iron overload in clinical practice, and take the approach of who, when, why and how to treat iron overload in MDS. Practical recommendations for treatment and monitoring are made. Evidence levels and grading of recommendations are provided for all clinical endpoints examined. PMID- 30286331 TI - TLE1 as an indicator of adverse prognosis in pediatric acute lymphoblastic leukemia. AB - PURPOSE: Acute lymphoblastic leukemia (ALL) is the most common type of cancer in children, and despite the high rate of cure (over 80%) it still has a big impact on morbidity and mortality. The Transducin-like enhancer of split 1 (TLE1), a transcriptional corepressor, has been described as dysregulated and recently emerged as a tumor marker in several cancer types, including hematologic malignancies. METHODS: In the present study TLE1 gene expression was evaluated by RT-qPCR. A total of 60 consecutive pathological ALL samples and 8 normal bone marrow samples were included. Associations between TLE1 levels and clinicopathological features were estimated using Mann-Whitney tests. RESULTS: TLE1 mRNA levels were significantly diminished in ALL samples when compared to normal counterparts (fold change -1.45, p-value 0.039). Lower TLE1 expression levels were associated with poorer prognostic features such as age at diagnosis (<1 or >9 years-old), absence of the Common Acute Lymphoblastic Leukemia Antigen (CALLA) and high white cell count. Considering immunophenotype, decreased expression of TLE1 was only evident for T-cell ALL, what was validated using gene expression profiling data available in public repositories. No associations with event or overall survival were observed. However, TLE1 expression was statistically different between patients who achieved complete clinical remission (CCR) from those that relapsed or died. CONCLUSION: These data are of particular interest and give support for a plausible role of TLE1 as a tumor suppressor in T cell ALL. Moreover, the prognostic value of this corepressor may assist ALL treatment stratification and suggest the need of alternative regimens. PMID- 30286332 TI - Magnetic resonance angiography contrast enhancement and combined 3D visualization of cerebral vasculature and white matter pathways. AB - Recently, in diffusion magnetic resonance imaging, the reconstruction and three dimensional rendering of white matter pathways have been introduced to clinical routine protocols. In a number of clinical situations, for example the preoperative analysis of vascular pathologies, the assessment of spatial relations between vascular structures and nearby fiber pathways is of vital interest for treatment planning. In this paper, we present an approach to the integrated vessel and fiber visualization, based on a novel vascular contrast enhancement operator for Magnetic Resonance Angiography (MRA) datasets. We propose a 3D dynamic programming method, allowing contrast enhancement of vascular structures and suppression of partial voluming effects at vessel borders. This makes it easier to visualize vascular structures by realtime volume rendering with surface shading. In contrast to maximum intensity projection, the method provides better depth cues and allows for easier spatial orientation. The integration of tractography-generated fibers as streamlines or streamtubes with correct visibility computation is performed by a combined volume and geometry renderer. In situations where tractography fails to provide reliable results, we use a line integral convolution method to assess white matter structures. In this manner, the spatial relations of vessels to fiber structures can be depicted by three-dimensional visualizations. We evaluate our approach with clinical data from patients with arteriovenous malformations, stenoses, aneurysms, and from healthy volunteers. PMID- 30286333 TI - Deep learning nuclei detection: A simple approach can deliver state-of-the-art results. AB - BACKGROUND: Deep convolutional neural networks have become a widespread tool for the detection of nuclei in histopathology images. Many implementations share a basic approach that includes generation of an intermediate map indicating the presence of a nucleus center, which we refer to as PMap. Nevertheless, these implementations often still differ in several parameters, resulting in different detection qualities. METHODS: We identified several essential parameters and configured the basic PMap approach using combinations of them. We thoroughly evaluated and compared various configurations on multiple datasets with respect to detection quality, efficiency and training effort. RESULTS: Post-processing of the PMap was found to have the largest impact on detection quality. Also, two different network architectures were identified that improve either detection quality or runtime performance. The best-performing configuration yields f1 measures of 0.816 on H&E stained images of colorectal adenocarcinomas and 0.819 on Ki-67 stained images of breast tumor tissue. On average, it was fully trained in less than 15,000 iterations and processed 4.15 megapixels per second at prediction time. CONCLUSIONS: The basic PMap approach is greatly affected by certain parameters. Our evaluation provides guidance on their impact and best settings. When configured properly, this simple and efficient approach can yield equal detection quality as more complex and time-consuming state-of-the-art approaches. PMID- 30286334 TI - Modulatory role of gabapentin against ovalbumin-induced asthma, bronchial and airway inflammation in mice. AB - Allergic asthma is a type of chronic immune-mediated inflammatory lung disorders with constantly increased worldwide prevalence. Gabapentin is an L-type calcium channel blocker used essentially as antiepileptic and recently has been indicated for management of post-operative and neuropathic pains as an anti-inflammatory. The current study was conducted to evaluate the anti-inflammatory and anti allergic properties of gabapentin in a mouse-model of Ovalbumin-induced allergic asthma. Mice received OVA (10 mg) adsorbed on Al(OH)3 on days 0 and 7 and were challenged by exposure to nebulized OVA solution (1%) form days 14-16. Asthma induction was associated with significant biochemical, oxidative and inflammatory imbalance. Daily oral gabapentin (50 mg/kg), significantly reduced lung inflammatory cells counts', serum LDH and catalase activities and lung/body weight index. Moreover, gabapentin significantly increased lung GSH concentration and enhanced SOD activity. Lung contents of TNFalpha, IL-4 and IL-13 significantly declined as well. IL-13; is the major contributor to airway hyper responsiveness; the charetrestic hallmark of asthma and IL-4; a major chemoattractant cytokine. Lung histopathology significantly improved parallel to the biochemical improvements. In conclusion; Gabapentin's modulatory effect on IL 4, IL-13 and TNFalpha activities accounts for the observed anti-inflammatory and anti-allergic properties.

AB - Phenyl 2,3,6,2',3',6'-hexa-O-acetyl-4'-S-acetyl-1,4,4'-trithio-beta-d-maltoside and its tri-, tetra- and pentasaccharide homologues were prepared by completely regio- and stereoselective photoinitiated thiol-ene coupling reactions of 2 acetoxy-glucal and 4-thioglucose type reaction partners. Complex protecting group strategies could be avoided since all thiols and glucals were prepared from a single starting material, phenyl 2,3,6-tri-O-acetyl-4-S-acetyl-1,4-dithio-beta-d glucopyranoside. The method represents a simple alternative to the known syntheses of similar products. PMID- 30286337 TI - Multiple sclerosis relapse presenting as an acute cardiomyopathy. AB - Multiple sclerosis is increasingly being recognized in association with cardiovascular dysfunction, which can manifest with cardiomyopathy, pulmonary edema (Kaplan et al., 2015), orthostasis (Kaplan et al., 2015) and other complications. Takotsubo cardiomyopathy is a syndrome of acute-onset ventricular dysfunction in the absence of obstructive coronary artery disease, which on rare occasion has been observed in the setting of demyelinated plaques in the brainstem. We report on two cases of Takotsubo cardiomyopathy with medullary demyelination secondary to multiple sclerosis.

AB - In an attempt to refine the H-bond-mediated Aglycone Delivery (HAD) glycosylation reaction reported herein is the synthesis of beta-glucosides using an ethylthio glucoside donor equipped with the remote 6-O-picoloyl substituent. Upon examining various aliphatic, aromatic, and carbohydrate acceptors, it was determined that both electronic and steric factors may greatly affect the stereoselectivity of the HAD reaction with this donor. PMID- 30286338 TI - Implications of irradiance exposure and non-photochemical quenching for multi wavelength (bbe FluoroProbe) fluorometry. AB - Multi-wavelength fluorometers, such as the bbe FluoroProbe (FP), measure excitation spectra of chlorophyll a (Chl-a) fluorescence to infer the abundance and composition of phytoplankton communities as well as the concentration of chromophoric dissolved organic matter (CDOM). Experiments were conducted on laboratory cultures and on natural communities of freshwater phytoplankton to determine how the response of phytoplankton to high irradiance might affect fluorometric estimates of community composition and concentrations of Chl-a and CDOM. Cultures of a representative cyanobacterium, bacillariophyte, synurophyte, cryptophyte, and chlorophyte revealed changes in Chl-a excitation spectra as irradiance was increased to saturating levels and non-photochemical quenching (NPQ) increased. The degree of change and resulting classification error varied among taxa, being strong for the synurophyte and cryptophyte but minimal for the cyanobacterium. Acute-exposure experiments on phytoplankton communities of varying taxonomic composition from five lakes yielded variable results on apparent community composition. There was a consistent decrease in CDOM estimates, whereas Chl-a estimates were generally increased. Subsequent exposure to low PAR relaxed NPQ and tended to reverse the effects of high irradiance on composition, total Chl-a, and CDOM estimates. Relaxation experiments on near surface communities in a sixth, large lake, Georgian Bay, showed that total Chl-a estimates increased by 44% on average when dark treatments were used to relax NPQ, though, in contrast to the findings from the small lakes, there was little effect on CDOM estimates. We observed a statistically-significant, negative linear relationship between the photon flux density of in situ irradiance and the accuracy of taxonomic assignment by FP in Georgian Bay. Not discounting the correlations between light intensity and the accuracy of the FP that were observed in this study, we conclude that the applicability of the reference spectra to the system under investigation is a more important consideration than variability in natural irradiance conditions. PMID- 30286339 TI - Effects of tanning on the stable isotopic compositions of hair. AB - We investigated the effect of tanning on the stable isotopic compositions (CNHOS) of hair keratin. Samples of hair from polar bear (Ursus maritimus) hides were collected before and after the tanning process from a commercial tannery. With the exception of sulphur isotopes, tanning did not alter the stable isotopic compositions of hair. delta34S values were slightly more positive (1 per mil) in hair that had gone through the tanning process, likely as a result of the tanning agent, alum (Al2(SO4)3) or exposure to sulphuric acid (H2SO4). This indicates that, with the exception of sulphur isotopes, hair keratin is resistant to subsequent isotopic alteration by the techniques used in tanning of animal hides and thus the original stable isotopic information is likely to be preserved in archived samples, such as taxidermic mounts and museum specimens. This is an important consideration when dealing with ecological and forensic applications to wildlife, such as evaluating provenance or migratory reconstructions, and so will assist in conservation efforts and investigations of trafficking and poaching. PMID- 30286340 TI - Application of the injury scales in homicides. AB - Injury scales have two main applications on homicide investigations, namely, to evaluate the severity of the victims' injuries and to identify the profiles of the offenders. However, few studies have examined the quality of the various injury scales in serving the two purposes. In this study, homicides from Shanghai and Wuhan, China (n=439) have been used to examine nine injury scales. The results showed that seven out of the nine scales were useful. Compared to one-to one homicides, offenders who killed two or more people tended to inflict more fatal injuries and made fewer number of attacks on the victims' heads and necks. Among all homicide cases, victims of stranger homicides tended to have fewer total number of wounds, as well as less severity of wounds on the heads, necks, and faces compared to those of intimate partner homicides. As to one-to-one homicides, only the severity of wounds on the face could assist to distinguish stranger homicides from intimate partner homicides. When a male victim died in a one-to-one homicide, the high number of total wounds along with the high number and severity of wounds on the head and neck could indicate that the offender was a female. PMID- 30286341 TI - Applicability and accuracy of Demirjian and Willems methods in a population of Eastern Chinese subadults. AB - BACKGROUND: To assess the validity of the Demirjian and Willems dental age estimation methods in a population of Eastern Chinese 11-18-year-old subadults. SAMPLES AND METHODS: A total of 1622 orthopantomograms (787 boys and 835 girls) aged from 11.00 to 18.99 years old from a Chinese Han population were evaluated in the study. Dental ages were calculated using both Demirjian and Willems method. Statistical significance was set at p<0.05 and for each method, discrepancies between chronological age (CA) and dental age (DA) were statistically analyzed by paired t-tests. Special age interval analysis was conducted by Chi-square tests to compare the accuracy of the Demirjian and the Willems methods. RESULTS: Demirjian method underestimated CA 0.66+/-1.45 y (p<0.001) in boys and 0.62+/-1.61 y (p<0.001) in girls while Willems method underestimated 0.90+/-1.32 y (p<0.001) and 0.97+/-1.56 y (p<0.001) in boys and girls, respectively. The mean absolute error (MAE) value between the CA and the DA (CA-DA) using the Demirjian method and the Willems method were 1.31 and 1.29 y for boys, respectively, and 1.35 and 1.43 y for girls, respectively. CONCLUSIONS: It is suggested that the Demirjian method was found to be more accurate compared with the Willems method. However, the Demirjian method may not be satisfactory for 11-18-year-old children of Eastern China. It is recommended that a modified Demirjian method for better dental age estimation for Eastern Chinese juvenile individuals. PMID- 30286343 TI - Screening for lysosomal acid lipase deficiency: A retrospective data mining study and evaluation of screening criteria. AB - BACKGROUND AND AIMS: Lysosomal acid lipase deficiency (LAL-D) is a lysosomal storage disorder. In severe cases, it can cause life-threatening organ failure due to lipid substrates accumulation. However, mild phenotypes of this disorder are increasingly recognized. The aim of this study is to determine the number of missed LAL-D patients in a large pediatric hospital population. METHODS: In a retrospective data mining study, the medical files of children, who visited the outpatient clinic at a university hospital between 2000 and 2016, with high plasma low density lipoprotein cholesterol (LDL-C) levels, were evaluated. Previously developed LAL-D screening criteria, with lipid and alanine aminotransferase (ALT) values adjusted for children, were used to analyze which children are suspect for LAL-D. For suspicion of LAL-D, at least 3 out of 5 screening criteria had to be met. Subsequently data on presentation and follow-up were collected to determine if the clinical picture was compatible with LAL-D. RESULTS: We identified 2037 children with high LDL-C levels. Of those, 36 children complied with >=3 screening criteria. Thirty-one of those had an underlying disorder other than LAL-D that explained the abnormalities and, in the 5 remaining children, ALT and lipid levels normalized spontaneously, thus excluding LAL-D. CONCLUSIONS: This study shows that retrospective data mining is unlikely to yield a significant number of LAL-D cases in children. The screening algorithm adjusted for children seems useful and accurate in the selection of children for further testing, suggesting it can be applied prospectively, although further validation is warranted. PMID- 30286342 TI - Keeping active: maintenance of physical activity after exercise programmes for older adults. AB - OBJECTIVES: To explore factors associated with maintenance of moderate-to vigorous physical activity (MVPA) in community-dwelling adults aged >=65 years after completing a 24-week exercise programme. STUDY DESIGN: This is a cohort study nested within a randomised controlled trial evaluating group- and home based exercise programmes for older people in England. METHODS: MVPA levels and factors potentially associated with physical activity (PA) were self-reported at recruitment, 6, 12, 18 and 24 months after exercise programme. Multilevel logistic regression estimated odds ratios (ORs) for achieving target MVPA level (150 min/week) 6-24 months after exercise programmes ended. RESULTS: Older people (OR per year increase: 0.89, 95% confidence interval [CI] 0.86, 0.93) and women (OR 0.47, 95% CI 0.33, 0.67) were less likely to achieve target MVPA. Those physically active at recruitment (OR 11.28, 95% CI 7.95, 16.01), with wider social networks (OR per unit increase in Lubben Social Network Scale: 1.06, 95% CI 1.03, 1.10) and performing more sit-to-stands in 30 s (OR for quartile 3 compared with quartile 1: 1.87, 95% CI 1.12, 3.10), were more likely to achieve target MVPA. Negative exercise expectations increased the odds of achieving target MVPA but only among the less active at recruitment (OR per unit increase in Outcome and Expectation for Exercise negative subscale: 1.90, 95% CI 1.39, 2.60). Associations did not differ significantly across the follow-up period. CONCLUSION: A range of factors are associated with maintenance of PA 6-24 months after exercise programmes. Factors are not more strongly associated with shorter vs longer term PA maintenance. Commissioners and providers should consider targeting maintenance interventions to those least likely to maintain PA. PMID- 30286344 TI - Overview of microbes based fabricated biogenic nanoparticles for water and wastewater treatment. AB - Treatment of toxic and emerging pollutants (T&EPs) is increasing the threats to the survival of conventional wastewater treatment (WWTs) technologies. The high installation and operational costs of advanced treatment technologies have shifted the research interest to the development of economical and reliable technology for management of T&EPs. Thus, recently biogenic nanoparticles (BNPs) fabricated using microbes/microorganisms are getting tremendous research interest due to their unique properties (i.e. high specific surface area, desired morphology, catalytic reactivity) for the biodegradation and biosorption of T&EPs. In addition, BNPs can be manufactured using metal contaminated water which indicates a hidden potential for resource recovery and utilization. Therefore, the present study discusses the adsorptive and catalytic performance of BNPs in the removal of T&EPs from water (W) and wastewater (WW). In addition, inspired by the superior performance of BNPs in advance WWT, a model of BNPs based WWT resource recovery and utilization process is also proposed. Finally, main issues i.e. mass production, leaching, poisoning/toxicity, regeneration, reusability and fabrication costs and process optimization are discussed which are main hinders in the transfer of BNPs based WWT technologies from laboratory to commercial scale. PMID- 30286345 TI - Microwave (MW) remediation of hydrocarbon contaminated soil using spent graphite An approach for waste as a resource. AB - In this study, we have explored the possibility of using an industrial waste for remediation of heavy fuel oil contaminated soil. Microwave (MW) heating in the presence of spent graphite (SG) from an auto forging industry has been used for the remediation. The physico-chemical characterization of SG and contaminated soil were done. Microwave remediation experiments were conducted in a lab scale unit and the effect of different parameters like microwave power, susceptor loading and treatment time were studied and optimized. The contaminated and decontaminated soils were analysed using GC-MS for total petroleum hydrocarbons (TPH), Total Organic Carbon and CHNS analyzers. Batch experiments of soil remediation showed that the TPH removal efficiencies (%) of 41.25, 87.77 and 91.18 at 300, 450 and 600 W respectively at SG concentration of 2.5 (wt. %) for a reaction time of 60 min. The addition of SG as susceptor enhanced the desorption of long chain hydrocarbons (C12-C29) present in the soil. Desorption of hydrocarbons from the soil fits well with first order kinetic model. This study successfully demonstrated the reuse of spent graphite (a lubricant waste) recovered from metal forging operations for remediating the fuel oil contaminated soil. PMID- 30286346 TI - Sampling methods and approaches to inform standardized detection of marine alien fouling species on recreational vessels. AB - Recreational vessels are important contributors to the spread of marine alien species, particularly in relation to secondary spread within novel regions. As such, these vessels should be considered a monitoring priority. The aim of this study was to identify a preferred method for monitoring recreational vessels for alien species, while simultaneously developing a framework that enables managers to objectively choose the most effective sampling approach given their financial constraints. Divers and a remotely operated vehicle (ROV) were considered in relation to four sampling approaches i.e. meanders, transects, inspection of niche areas and the collection of quadrats. Each was applied to the same 53 vessels which represented a spectrum of hull fouling cover. The most effective methods were diver scrape quadrats (Range of alien species numbers per quadrat: 0 9, Total alien species: 20) and inspections of niche areas (Range of alien species numbers: 0-5, Total alien species: 9). All methods employed using an ROV had low efficacy and incurred high costs. While scrape samples were one of the most expensive methods, this was offset by the lowest cost per species detected. Thus, it is recommended that monitoring programmes utilize scrape samples and niche area inspections, but when faced with financial constraints, diver meanders and niche inspections offer sound alternatives for detecting alien species. PMID- 30286348 TI - A biodegradable biomass-based polymeric composite for slow release and water retention. AB - Slow-release fertilizer has been proven to be more effective than traditional fertilizer for providing a long-term stable nutrient supply. Although such fertilizers have been widely investigated, their water-retention properties and biodegradability have not been fully analysed. Composites of fertilizers and polymers provide opportunities to prepare new types of fertilizer with enhanced properties for real applications. Chicken feather protein-graft-poly(potassium acrylate)-polyvinyl alcohol semi-interpenetrating networks forming a super absorbent resin combined with nitrogen (N) and phosphorus (P) (CFP-g-PKA/PVA/NP semi-IPNs SAR) was prepared. The chemically bonded or physically embedded fertilizer compound could be released form the resin matrix to the surrounding soil under irrigation. The synthesis mechanism, morphology, and chemical and mechanical structure of the synthesized composites were investigated. The reactant doses were optimized through response surface methodology (RSM). A 30 day field trial of the prepared SAR was applied to detect the influence of sample particle size, soil salinity, pH, and moisture content on the slow-release behaviour of N and P. The maximum release values of N and P from the composites were 69.46% N and 65.23% P. A 120-day soil burying experiment and 30-day Aspergillus niger (A. niger) inoculation were performed, and the biodegradability and change in microstructure were monitored. The addition of SAR to soil could also improve the water-retention ability of the soil.

AB - Previous research explains the various factors that motivate or discourage the owner-managers of small firms to behave sustainably. However, it has failed to develop a meaningful understanding of how these factors inter-relate or combine to influence their decisions. This research identifies and explains how socio cultural and industrial norms influence the intentions and behaviours towards sustainability of owner-managers of small tourism firms. This grounded theory study shows how selective peer association allows the use of norms that match one's values to predict the difficulties, benefits and therefore justification for pro-sustainability (in)action. Locally-held socio-cultural norms determine what is commonly (dis)approved of through reflective and comparative processes. Connectedness to the locality triggers empathy for nature and the local society, but not a corresponding sense of responsibility. This dissonance is managed by allocating responsibility to industry actors perceived as more powerful, particularly tour operators and consumers, and to the widespread greed and short term culture dominating the sector.

AB - Here in, we presented a facile one-step method for the synthesis of Graphene oxide-silver (GO-Ag) nanocomposite and its applications as a sorbent for the elimination of some toxic pollutants from aqueous medium, as an efficient catalyst in the individual as well as simultaneous reduction reactions of multiple compounds, and as an antibacterial agent for the destruction of some harmful microorganisms existent in wastewater. GO was prepared using a modified Hummers method and Ag nanoparticles were integrated on GO sheets by chemical reduction of Ag+ ions on the surfaces of GO sheets. The composition and morphology of the nanocomposite was extensively characterized with elemental dispersive X-ray analysis (EDX), Fourier transform infra-red (FT-IR) spectroscopy, transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), and thermal gravimetric analysis (TGA). The GO-Ag nanocomposite demonstrated remarkable adsorption capacities and recyclability for malachite green (MG) and ethyl violet (EV) dyes. Various experimental parameters affecting adsorptive behavior of nanocomposite like temperature, pH, time of contact between dye and adsorbent, and adsorbent dose were evaluated thoroughly. Experimental data was simulated with different adsorption isotherms and kinetic models to evaluate adsorption behavior of both dyes and results confirmed the adsorption of both the dyes to be followed by pseudo 2nd order kinetic model and Langmuir adsorption model. Moreover, adsorbent was regenerated in suitable media for both dyes without any loss in removal efficiency. The catalytic performance for the 2-nitroaniline (2-NA) reduction was investigated in detail. Most importantly, the prepared nanocomposite was found to have potential to adsorb multiple pollutants all together as well as to catalyze the simultaneous reduction of a mixture of dyes (MG, MO, and EV) and 2-NA. An additional advantage of the GO-Ag nanocomposite was its antibacterial activity acquired to the presence of Ag nanoparticles. Two bacterial strains (Gram negative bacterium, E. coli and the Gram-positive bacterium, S. aureus) were used to test antibacterial activity of composite and the results confirmed the remarkable performance of the nanocomposite in destroying harmful pathogens.

AB - The mechanistic model (BIO_ALGAE) for microalgae-bacteria based wastewater treatment systems simulation was validated in the long-term (months) using experimental results from a pilot high rate algal pond (HRAP) treating municipal wastewater. Simulated results were compared with data gathered during two different seasons (summer and winter), and with the HRAP operating at different hydraulic retention times (HRT, 4 and 8 days, respectively). The model was able to simulate with a good degree of accuracy the dynamics of different components in the pond, including the total biomass (bacteria and microalgae). By means of practical study cases, the influences of different HRT operating strategies and seasonal variations of temperature and irradiance were investigated for the relative proportion of microalgae and bacteria, and biomass production over a year cycle. Model predictions show that the proportion of microalgae in the microalgal/bacterial biomass is quite similar in warmer months if the pond is operated with 8-day HRT (76-78%) or 4-day HRT (60-75%). Significant differences were observed in colder months (4-day HRT (27-33%) and 8-day HRT (65-68%)). The model identified a scenario in which overall microalgae production and ammonium removal efficiency were optimized. By operating the HRAP with lower HRT (4 days) in warmer months and higher HRT (8 days) in colder months, the average annual microalgae production increased up to 14.1 gTSS m-2d-1, in contrast with 10.2 gTSS m-2d-1 and 9.2 gTSS m-2d-1 operating with constant HRAP (4 and 8 days, respectively) over a year cycle. PMID- 30286351 TI - Factors controlling sediment and nutrient fluxes in a small microtidal salt marsh within the Venice Lagoon. AB - Coastal salt marshes are among the Earth's most productive ecosystems and provide a number of ecosystem services. Water quality regulation by storing, transforming and releasing nutrients, organic matter and suspended sediment is recognized as one of the most important functions of salt marshes. The self-purification capacity of intertidal ecosystems contributes to mitigating nutrient inputs, acting as a buffer zone between watersheds and coastal waters, especially in relation to climate change and the increasing frequency of impulsive extreme events. Understanding sediment and nutrient fluxes and assessing the mechanisms that control them are valuable for the preservation and future restoration of salt marshes and for enhancing their effectiveness in providing water quality regulation services. To investigate the main driving factors in microtidal environments, changes in suspended sediment and nutrient concentrations were measured during several tidal cycles in a small microtidal reconstructed salt marsh in the Venice Lagoon, which was selected as the experimental site. The tidal amplitude, nutrients and total suspended solid concentrations were measured during 6 tidal cycles between September 2011 and October 2013. The water discharge was derived by forcing the hydrodynamic MIKE-DHI numerical model with the measured tidal levels. Fluxes were assessed by coupling field data with the calculated discharges. The salt marsh filtering function was related to the inflow matter concentrations and tidal amplitude. When high suspended solid and nutrient concentrations enter the salt marsh, accumulation processes prevail on release. In contrast, in the case of low concentrations and high tidal excursion, the salt marsh functions as a nutrient and sediment source. During all campaigns, the nitrogen removal function was more effective within the intertidal vegetated areas. Sediment release was the dominant process in the outermost creek, whereas sedimentation prevailed in the inner area of the salt marsh because of the attenuation of hydrodynamic forcing during tide propagation.

AB - As the central part of eastern China, the Yangtze River Delta (YRD) region, with its rapid economic growth and industrial expansion, has experienced severe air quality issues. In this study, the monthly variation and interaction between aerosol direct radiative forcing (ADRF) and aerosol vertical structure during 2013-2015 over the YRD were investigated using ground-based observations from a Micro Pulse Lidar (MPL) and a CE-318 sun-photometer. Combining satellite products from MODIS and CALIPSO, and reanalysis wind fields, an integrated discussion of a biomass burning episode in Hangzhou during August 2015 was conducted by applying analysis of optical properties, planetary boundary layer (PBL), spatial-temporal and vertical distributions, backward trajectories, Potential Source Contribution Function (PSCF), and Concentration Weighted Trajectory (CWT). The results reveal that a shallower PBL coincides with higher scattering extinction at low altitude, resulting in less heating to the atmosphere and radiative forcing to the surface, which in turn further depresses the PBL. In months with a deeper PBL, the extinction coefficient decreases rapidly with altitude, showing stronger atmospheric heating effects and ADRF to the surface, facilitating the turbulence and vertical diffusion of aerosol particles, which further reduces the extinction and raises the PBL. Because of the hygroscopic growth facilitated by high relative humidity, June stands out for its high scattering extinction coefficient and relatively low PBL, and the reduced ADRF at the surface and the enhanced cooling effect on near-surface layer in turn depresses the PBL. Absorptive aerosols transported from biomass burning events located in Zhejiang, Jiangxi, and Taiwan provinces at 1.5 km, result in high ADRF efficiency for atmospheric heating. And the enhanced heating effect on near-surface layer caused by absorptive particles facilitates PBL development in August over the YRD.

AB - Stream temperatures, which influence dynamics and distributions of the aquatic species and kinetics of biochemical reactions, are expected to be altered by the climate change. Therefore, predicting the impacts of climate change on stream temperature is helpful for integrated water resources management. In this study, our previously developed Soil and Water Assessment Tool (SWAT) equilibrium temperature model, which considers both the impacts of meteorological condition and hydrological processes, was used to assess the climate change impact on the stream temperature regimes in the Athabasca River Basin (ARB), a cold climate region watershed of western Canada. The streamflow and stream temperatures were calibrated and validated first in the baseline period, using multi-site observed data in the ARB. Then, climate change impact assessments were conducted based on three climate models under the Representative Concentration Pathways 4.6 and 8.5 scenarios. Results showed that warmer and wetter future condition would prevail in the ARB. As a result, streamflow in the basin would increase despite the projected increases in evapotranspiration due to warmer condition. On the basin scale, annual stream temperatures are expected to increase by 0.8 to 1.1 degrees C in mid-century and by 1.6 to 3.1 degrees C in late century. Moreover, the stream temperature changes showed a marked temporal pattern with the highest increases (2.0 to 7.4 degrees C) in summer. The increasing stream temperatures would affect water quality dynamics in the ARB by decreasing dissolved oxygen concentrations and increasing biochemical reaction rates in the streams. Such spatial-temporal changes in stream temperature regimes in future period would also affect aquatic species, thus require appropriate management measures to attenuate the impacts.

AB - Energy uncoupling technology was applied to the membrane process to control the problem of bio-fouling. Different dosages of uncoupler (2,4-dinitrophenol, DNP) were added to the activated sludge, and a short-term ultrafiltration test was systematically investigated for analyzing membrane fouling potential and underlying mechanisms. Ultrafiltration membrane was used and made of polyether sulfone with a molecular weight cut off (MWCO) of 150 kDa. Results indicated that low DNP concentration (15-30 mg/g VSS) aggravated membrane fouling because more soluble microbial products were released and then rejected by the membrane, which significantly increased cake layer resistance compared with the control. Conversely, a high dosage of DNP (45 mg/g VSS) retarded membrane fouling owing to the high inhibition of extracellular polymeric substances (proteins and polysaccharides) of the sludge, which effectively prevented the formation of cake layer on the membrane surface. Furthermore, analyses of fouling model revealed that a high dosage of DNP delayed the fouling model from pore blocking transition to cake filtration, whereas this transition process was accelerated in the low dosage scenario. PMID- 30286355 TI - Preliminary study of long-range transport of halogenated flame retardants using Antarctic marine mammals. AB - Eight PBDE congeners, three emerging brominated flame retardants, five dechloranes and eight MeO-PBDEs were monitored in tissues (muscular, adipose, brain) and fur of southern elephant seal and Antarctic fur seal of the South Shetland Islands, Antarctic Peninsula. Total PBDEs and total dechloranes concentrations ranged between n.d.-6 ng/g lw. While PBDEs were not detected in brain tissue, Dec 602 was found in brain tissue of both seal species indicating that dechloranes -with potential neurological toxicity- could cross the blood brain barrier. Emerging brominated flame retardants were not detected in any sample and only two MeO-PBDEs, which are of natural origin, were found. The presence of the detected compounds in biota from the Antarctic evidences their long-range transportation, being of special interest the detection of emerging compounds such as dechloranes. This is the first time that these contaminants have been detected in marine mammals from the Antarctic. BDE-47 concentrations were lower than previously reported for the same species, suggesting a successful effect of the existing regulation and bans on PBDEs. CAPSULE ABSTRACT: Halogenated flame retardants were in tissues of Antarctic seals proving long range transport. Dechloranes showed similar behaviour to PBDEs, additionally they crossed the BBB.

AB - Ria de Aveiro represents a coastal territory, in which its natural capital, mostly classified under a Natura 2000 network of protected areas, is of paramount importance for the regional and national economy, supporting harbour activities and maritime traffic, agriculture, commercial fisheries, aquaculture, manufacturing, tourism, sports and recreational activities. Current and foreseen changes connected to human activities, namely land and water uses and potential conflicts, in frame of environmental policies, sustainable economic development and human well-being require the implementation of ecosystem-based management (EBM) planning processes considering the connectivity across marine, transitional, freshwater, and terrestrial domains. The main objective is to elaborate on the co-development of the EBM planning process across the three water domains, all characterized by high biodiversity and by the wide range of services provided by ecosystems and their abiotic components, for the mitigation of impacts from the management plan under implementation. The approach used follows a stepwise procedure in frame of resilience principles, considering the analysis of the relationship between the social and ecological components and on how these can be connected through risk assessment and a spatial multi-criteria analysis based on the delivery of ecosystem services. Stakeholders' perception matched the ecosystem services provisioning risk assessment and supported the planning EBM response that consist in saltmarshes and seagrasses meadows restoration programs. Compliance of the proposed measures is achievable regarding policies (policy targets and policy instruments) and feasibility (scientific and technological knowledge and financial resources). The EBM response can support the Vouga estuary management plan and regional smart specialization (RIS3 Centro). PMID- 30286357 TI - Microplastics in the Northwestern Pacific: Abundance, distribution, and characteristics. AB - Prevalence of microplastics (MPs) throughout the world's oceans has raised growing concerns due to its detrimental effects on the environment and living organisms. Most recent studies of MPs, however, have focused on the estuaries and coastal regions. There is a lack of study of MPs pollution in the open ocean. In the present study, we conducted field observations to investigate the abundance, spatial distribution, and characteristics (composite, size, color, shape and surface morphology) of MPs at the surface of the Northwestern Pacific Ocean. Samples of MPs were collected at 18 field stations in the Northwestern Pacific Ocean using a surface manta trawl with a mesh size of ~330 MUm and width of 1 m from August 25 to September 26, 2017. The MPs were characterized using light microscopy, Micro-Raman spectroscopy, and scanning electron microscopy (SEM). Our field survey results indicate the ubiquity of MPs at all stations with an abundance from 6.4 * 102 items km-2 to 4.2 * 104 items km-2 and an average abundance of 1.0 * 104 items km-2. The Micro-Raman spectroscopic analysis of the MPs samples collected during our field survey indicates that the dominant MPs is polyethylene (57.8%), followed by polypropylene (36.0%) and nylon (3.4%). The individual chemical compositions of MPs from the stations within the latitude range 123-146 degrees E are comparable with each other, with PE being the dominating composition. Similar chemical fingerprints were observed at these field stations, suggesting that the MPs originated from similar sources. In contrast, the major MPs at the field stations adjacent to Japan is polypropylene, which may originate from the nearby land along the coast of Japan. Physical oceanography parameters were also collected at these stations. The spatial distribution of MPs is largely attributed to the combined effects of flow pattern, adjacent ocean circulation eddies, the Kuroshio and Kuroshio Extension system. PMID- 30286358 TI - Non-native freshwater fauna in Portugal: A review. AB - We present the most updated list of non-native freshwater fauna established in Portugal, including the Azores and Madeira archipelagos. This list includes 67 species at national level but corresponds to 84 species records, of which 53 are in the mainland, 23 in the Azores and 8 in Madeira archipelagos. We also discuss the progression of the cumulative number of introductions since 1800 and identify the most probable vectors of introduction, main taxonomic groups and their regions of origin. Furthermore, we review the existing knowledge about ecological and economic impacts, invasion risk and potential distribution of invaders, under present and future climatic conditions, and the applied management actions, including the production of legislation. Along the 20th century the number of successful introductions increased at an approximate rate of two new species per decade until the beginning of 1970s. Since then, this rate increased to about 14 new species per decade. These introductions were mainly a result of fisheries, as contaminants or for ornamental purposes. Fish and mollusks are the taxonomic groups with more established species, representing more than half of the total. Most species (>70%) are native from other regions of Europe and North America. Studies about ecological or socioeconomic impacts are more common for fish, crustaceans and mollusks. Impacts for most amphibians, reptiles and mammals are not thoroughly studied. A few studies on the impacts and management actions of health-threatening mosquitoes are also available. The potential distribution in the Portuguese territory was modelled for 26 species. Only a minority of these models provides projections of distributions under scenarios of future climate change. A comparison of the Portuguese and EU legislation shows large discrepancies in the invasive species lists. Using the EU list and a ranking procedure for the national context, we identify freshwater species of high national concern for which actions are urgently needed. PMID- 30286359 TI - The impact of socio-economic development and climate change on E. coli loads and concentrations in Kabul River, Pakistan. AB - Microbial pollution is a major problem worldwide. High concentrations of Escherichia coli have been found in Kabul River in Pakistan. E. coli concentrations vary under different socio-economic conditions, such as population and livestock densities, urbanisation, sanitation and treatment of wastewater and manure, and climate-change aspects, such as floods and droughts. In this paper, we assess potential future E. coli loads and concentrations in the Kabul River using the Soil and Water Assessment Tool with scenarios that are based on the most recent Shared Socio-economic Pathways and Representative Concentration Pathways (SSPs and RCPs) developed for the Intergovernmental Panel on Climate Change (IPCC). Scenario_1 considers moderate population and livestock density growth, planned urbanisation and strongly improved wastewater and manure treatment (based on SSP1, "Sustainability"), and moderate climate change (RCP4.5, moderate greenhouse gas (GHG) emissions). Scenario_2 considers strong population and livestock density growth, moderate urbanisation, slightly improved wastewater treatment, no manure treatment (based on SSP3, "Regional rivalry") and strong climate change (RCP8.5, high GHG emissions). Simulated E. coli responses to Scenario_2 suggest a mid-century increase in loads by 111% and a late century increase of 201% compared to baseline loads. Similarly, simulated E. coli loads are reduced by 60% for the mid-century and 78% for the late century compared to the baseline loads. When additional treatment is simulated in Scenario_1, the loads are reduced even further by 94%, 92% and 99.3% compared to the baseline concentrations when additional tertiary treatment, manure treatment or both have been applied respectively. This study is one of the first to apply combined socio economic development and climate change scenario analysis with an E. coli concentration model to better understand how these concentrations may change in the future. The scenario analysis shows that reducing E. coli concentrations in Pakistan's rivers is possible, but requires strongly improved waste water treatment and manure management measures. PMID- 30286360 TI - A modeling study of the peroxyacetyl nitrate (PAN) during a wintertime haze event in Beijing, China. AB - Peroxyacetyl nitrate (PAN), as the second most important photochemical pollutant, could threaten human health and terrestrial ecosystem. Observed high PAN concentrations in wintertime in Beijing are comparable to those in summertime when photochemistry is strong. In this study, we investigated the variations of concentrations of PAN and other related chemical species during a haze event on February 13-16, 2017 in Beijing using a combination of in-situ observations and the WRF-Chem model simulation. During this episode, the observed mean (maximum) PAN concentrations at the urban and rural sites were 1.9 (4.7) ppb and 1.8 (4.3) ppb, respectively. Model evaluation showed that the simulation with CBM-Z gas phase scheme performed much better than simulation using the RADM2 scheme, which mainly results from the accurate representation of the reaction rates for PAN formation through CH3C(O)O2 radicals and NO2 in the CBM-Z scheme. But simulated PAN concentrations in Beijing were still underpredicted using the CBM-Z scheme, likely due to the underestimation of VOC emissions. Since the lifetime of PAN becomes as long as several days in wintertime due to lower temperature, it could be conducive to be accumulated and transported. Sensitivity simulation demonstrated that local sources accounted for about 15%-30% of mean PAN concentrations over most of Beijing during the event, lower than that of PM2.5 (25%-60%). These suggest that during Beijing wintertime polluted days, increased PAN concentration, which is dominantly contributed by regional transport from surrounding areas, will cause more health concerns, and its control strategies need larger regional efforts than those conducted for PM2.5. PMID- 30286361 TI - DNA analysis of hairs in a suspected case of child abuse. AB - Hairs are often used for DNA analysis in criminal investigations. DNA analysis of hairs with root sheaths is easy in many cases, but analyses using only the shaft or tip of the hair are often difficult. Here we describe a suspected case of child abuse in which we were commissioned to perform DNA analysis. Among 100 hairs, PCR amplification was succeeded in 99 samples, and as a result of direct sequencing, mitochondrial DNA (mtDNA) of the 99 hairs were classified into 6 types. The most common type was the 8-base substitution type of 16,168T-16,172C 16,183C-16,189C-16,217C-16,249C-16,325C-16,390A, which was observed in 86 hairs. This corresponded to the type of the victim. Total 736 STRs (75.5%) in 975 loci of 65 hairs could be typed, and only an amelogenin locus was typed in another hair. All 15 loci were typed in 10 hairs. STR types of 65 (98.5%) in 66 hairs were consistent with that of the victim. From 10 naturally-shed hair of a person, only 37 STRs (30.8%) in 120 loci of 8 hairs were typed, and all 15 loci could not be typed in these hairs. This difference in success rates of STR analysis suggested strongly that the hairs in this case were not shed naturally but forcibly, and the relevance to child abuse was suspected. PMID- 30286362 TI - Intralipid(r) may represent a new hope for patients with reproductive failures and simultaneously an over-immune endometrial activation. AB - PROBLEM: Continuous failures to achieve a pregnancy despite effective embryo transfers is extremely distressing for couples. In consequence, many adjuvant therapies to IVF have been proposed to achieve an "ideal" immune environment. We here focus on Intralipid(r) therapy (IL) reported to have immunosuppressive properties on NK cells. METHOD OF STUDY: 94 patients exhibited an immune profile of endometrial over-immune activation and an history of repeated implantation failures despite multiple embryos transfers (RIF). They received a slow perfusion of Intralipid(r). We here report the live birth rate following the procedure at the next embryo transfer. To get new insight on its mechanism of action, a second immune profiling had been performed under Intralipid(r) before the embryo transfer. RESULTS: The live birth rate of the RIF cohort treated with Intralipid(r) reached 54% (51/94) at the next embryo transfer. In patients successfully pregnant under Intralipid(r) who benefitted of a test of sensibility before the embryo transfer, we observed a significant decrease of the three biomarkers used to diagnose the over-immune endometrial activation (CD56 cells; IL-18/TWEAK, IL-14/FN-14). CONCLUSIONS: Double blind placebo versus Intralipid(r) studies should be conducted. Intralipid(r) may be an option to explore in RIF patients who exhibit an over-immune activation of uNK cells. PMID- 30286363 TI - TVT Abbrevo and Miniarc suburethral sling in women with stress urinary incontinence - A randomised controlled trial. AB - INTRODUCTION: Single incision slings (SIS) were introduced in an attempt to decrease the complications associated with retropubic and transobturator slings. The TVT Abbrevo is a modification of the TVT-O with a reduced length and less immediate postoperative pain. The Miniarc SIS has been shown to be equivalent to outside-in transobturator sling, Monarc at 12 month follow-up. OBJECTIVE: To evaluate objective and subjective outcomes of MiniArc SIS and TVT Abbrevo midurethral sling (MUS) in women with stress urinary incontinence. METHODS: Female subjects who were assessed and referred for stress urinary incontinence surgery were eligible to participate in this study. Exclusion criteria included women with intrinsic sphincter deficiency previous failed midurethral or fascial sling, untreated detrusor overactivity or significant voiding dysfunction. Patients' randomisation was performed with computer-generated blocks of 4-8, with concealed allocation. Assuming an objective cure rate of 90% for TVT AbbrevoTMwith a power of 80%, a sample size of 79 in each arm was required to detect a clinical difference of 15%, using a one sided alpha of 0.05. The target recruitment number was 220 allowing for an attrition rate of 15%. Institution ethics approval (11261B) was obtained and the trial was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12611001151921). Routine preoperative assessment was conducted for objective data, whilst patient reported outcome tools (PRO) were utilised for subjective outcomes. These include ICIQ UI SF, ICIQ OAB, IIQ7, EQ5D, PISQ12, PGIs & PGII. TVT AbbrevoTM or MiniarcTMwere performed in a standardized fashion, together with any concomitant prolapse surgery. Review was conducted at 6 weeks and at 6 and 12 months. Objective cure was defined as a negative cough stress test with a comfortably full bladder. Subjective cure was defined as no report of leakage with physical exertion. All Data was collected and outcomes were analysed statistically. RESULTS: Between February 2011 and January 2016,a total of 246 women were randomized to receive MiniArc (121) or TVT Abbrevo (125). Baseline characteristics were clinically balanced in both groups. At 6 months subjective (94.4% vs 95.7% p=0.74) and Objective (92.9% vs 95.9% p=0.49) cure rates were high and not statistically different. At 12 months there were also no differences in subjective (73.6% vs 76.9% p=0.73) or objective (90.5% vs 96.0% p=0.21) cure rates. No differences were found in functional outcomes or when adjusted for potential confounding factors such as age, parity, BMI or menopausal status. CONCLUSION: We found no significant differences in subjective and objective cure rates at 6 and 12months between MiniArc and TVT Abbrevo. PMID- 30286364 TI - MELF pattern of myometrial invasion and role in possible endometrial cancer diagnostic pathway: A systematic review of the literature. AB - Microcystic, elongated, fragmented (MELF) pattern of myometrial invasion has been proposed as a prognostic marker in patients with endometrial carcinoma (EC). Its prognostic and predictive effect still remains elusive. The aim of the present study is to accumulate the current knowledge on the role of MELF pattern in the prognosis and survival of patients with EC. Medline, Scopus, Google Scholar, and Clinicaltrials.gov databases were searched for articles published up to May 2018, along with the references of all articles. Prospective and retrospective trials reporting outcomes of cases with EC who were examined for MELF pattern were considered eligible for inclusion in the present systematic review. Of the 196 records screened, 14 were considered eligible. A total of 14 studies which comprised 588 women were finally included in the present systematic review. All the included patients were evaluated for presence of MELF pattern of myometrial invasion. MELF positive (+) patients were more likely to present with larger and higher grade tumors, lymph node metastasis, lymphovascular invasion and >50% myometrial invasion. No difference was reported in disease free survival (DFS) and disease specific survival (DSS) as well as in vaginal recurrence rates. MELF (+) was reported as a significant indicator of survival. In conclusion, MELF pattern of myometrial invasion plays a critical role in lymphovascular space invasion and lymph node metastasis in patients with EC. Regardless, its implication in survival and recurrences is ill determined. PMID- 30286365 TI - 2D USS of the pelvic floor in the 3rd trimester versus mode of delivery. AB - OBJECTIVE: Biomechanics of pelvic floor muscles is becoming an important field of research in understanding a complex process of labour. Current evidence indicates that the levator ani stretches to allow passage of the fetus through the birth canal. We sought to identify properties of the functional female pelvic floor during pregnancy that could help to predict the mode of delivery, especially in women who underwent caesarean section in the past. METHODS: A single centre prospective cohort study of pregnant women in the 3rd trimester attending antenatal clinic. Participants were categorised into three groups: 1. nulliparous, 2. previous one vaginal delivery and 3. previous one caesarean section who chose a trial of labour in their current pregnancy. All women underwent ultrasonographic evaluation of their pelvic floor muscles. Distensibility and the mode of delivery were assessed in participants' current pregnancies. The primary outcome was the mode of delivery. ANOVA test was used for statistical analysis. RESULTS: 133 women were included: 55 nulliparous, 52 primiparous (previous one vaginal birth), and 26 primiparous (previous one LSCS and planned for vaginal delivery after caesarean (VBAC)). Participants were scanned at an average gestation of 32 weeks. The inter-observer reliability test for puborectalis distensibility was good (kappa 0.75). Overall, women who delivered vaginally had a more distensible puborectalis muscle than those who delivered by emergency LSCS regardless of their previous type of delivery. Women who underwent a successful VBAC had less distensible pelvic floor muscles compared to their nulliparous and primiparous counterparts (who delivered vaginally in the past). CONCLUSION: These results support our basic conceptual theory of puborectalis muscle distensibility influencing the mode of delivery and endorse application of dynamic pelvic floor ultrasound in future studies. We identified measurable differences in the functional female pelvic anatomy aiding a better understanding of physiology of the labour. There are trends towards lesser distensibility in women who delivered by LSCS. PMID- 30286366 TI - An investigation of associations between experience of childhood trauma and political violence and theory of mind impairments in schizophrenia. AB - There has been little examination of the association between trauma and cognitive deficits seen in individuals diagnosed with schizophrenia. Theory of Mind (ToM) impairments are a significant feature of schizophrenia but it remains unclear as to why these deficits are so prevalent in this population. This study aimed to explore associations between ToM deficits and specific forms of childhood adversities in a schizophrenia population. The study sample comprised of 66 adults with a confirmed diagnosis of schizophrenia, attending mental health services in Northern Ireland. Assessments were completed to ascertain if individuals had prior experience of sexual or physical abuse, emotional neglect or experience of the political violence of Northern Ireland's "Troubles", and the Gardner Hinting Test was applied to assess ToM ability. Backwards stepwise regression analyses demonstrated that emotional neglect, specifically during early childhood (0-6 years) predicted ToM impairments in this group. Conflict related trauma was also associated with ToM but was not an independent significant predictor of ToM deficits. This is the first study to examine links between specific forms of childhood adversity and ToM impairments in individuals diagnosed with schizophrenia. Potential underpinning psychological mechanisms are considered and implications for clinical practice are discussed. PMID- 30286367 TI - Stigma and discrimination in individuals with first episode psychosis; one year after first contact with psychiatric services. AB - Stigma and discrimination in psychotic illness has not been robustly studied in those presenting with their first episode of psychosis (FEP). We prospectively examined patterns of stigma and discrimination one year after index presentation with FEP and correlates with baseline demographic, symptom burden, depression and level of functioning. We surveyed 101 subjects using the Discrimination and Stigma Scale-12 (DISC-12) and administered the Positive and Negative Syndrome Scale (PANSS), Global Assessment of Function (GAF) and the Patient Health Questionnaire (PHQ-9). Discrimination was experienced in 76%; being shunned by people because of mental illness, making and keeping friends and from family were most affected. Older age, female gender, marital status and a family history of mental illness were significantly associated with higher unfair treatment. Higher PANSS score at baseline, 3-month and 12-month was significantly associated with lower positive treatment, higher stopping self-scores and lower overcoming stigma scores, respectively. Higher GAF score at 12-month was associated with higher overcoming stigma scores. Lower PHQ-9 scores was significantly correlated with overcoming stigma. In conclusion, stigma and discrimination is highly prevalent among individuals with FEP; the extent is associated with specific demographic variables, symptom burden, presence of depression and level of functioning. Limitations include selection bias of subjects, potential underestimation of stigma from participants who defaulted or refused to participate and inability to establish causality.

Although DISC1 gene has been shown as a risk factor for schizophrenia in some reports, there is a lack of a consensus. We therefore performed separate meta-analyses aiming to assess the associations between DISC1 SNPs and schizophrenia risk. We found that SNP rs821597 is significantly associated with schizophrenia risk in terms of both allelic and genotypic distribution, while SNP rs821616 is associated with schizophrenia in terms of genotypic distribution, especially in cases above 40 years old. PMID- 30286369 TI - Chinese version of the clinical learning environment comparison survey: Assessment of reliability and validity. AB - BACKGROUND: Simulation is recommended as a substitute for clinical practice among nursing students. No current guidelines exist regarding the accurate percentage of simulation hours versus clinical practice hours. Comparing simulation with clinical practice is needed so that both strategies can be optimally combined in nursing education. The 29-item Clinical Learning Environment Comparison Survey (CLECS) is validated to compare the traditional and simulated clinical environment in meeting nursing students' learning needs. This type of tool is not available in China. OBJECTIVES: This study aimed to translate and test the psychometric properties of CLECS for Chinese undergraduate nursing students. DESIGN: This is a cross-sectional study. SETTINGS: Two nursing schools in Central and East China. PARTICIPANTS: A total of 179 undergraduate nursing students who had participated in both traditional and high fidelity simulated clinical practice were recruited. METHODS: A standard procedure with forward translation, back translation, cultural adaptation and pilot testing was followed to test the CLECS (Chinese version). An exploratory factor analysis was used to establish a modified factor structure of CLECS (Chinese version); a confirmatory factor analysis verified its construct validity. Reliability of the CLECS (Chinese version) was estimated using the intraclass correlation coefficients (ICCs) and Cronbach's alpha coefficients. RESULTS: The exploratory factor analyses explained 61.43% and 60.11% of the total variances in traditional and simulated clinical environment. The proposed factor solution of the CLECS (Chinese version) obtained satisfactory model fit and nesting model between two nursing schools. In the proposed model, ICCs were 0.61 and 0.93, and Cronbach's alpha coefficients were 0.75 and 0.95 in the traditional and simulated clinical environment. CONCLUSIONS: The CLECS (Chinese version) showed satisfactory reliability and validity among Chinese undergraduate nursing students. Further validation of the CLECS (Chinese version) is needed in a more representative and larger sample. The CLECS (Chinese version) should be further tested as an effective tool to compare the traditional and simulated clinical practice among Chinese nursing schools. PMID- 30286370 TI - Mobile persuasive technology for the teaching and learning in surgical safety: Content validation. AB - BACKGROUND: Patient safety is a fundamental component of high-quality delivery of health care. However, despite scientific advances, surgical patients continue to face risks. Among the most common complications in surgery are operations on the wrong patient, performance of the wrong procedure or operation on the wrong surgical site, lack of adequate or required equipment, failure to prevent blood loss, and surgical items left inside patients. In this context, the planning and development of innovative educational strategies is important for prevention of adverse events and the improvement of surgical patient safety culture. OBJECTIVE: To describe the process of validating the content of mobile technology for education about surgical safety. METHODS: Content validation using the Delphi technique was carried out from December 2015 to January 2016 at a Federal University in South Brazil. Content development and animations were produced by the authors from a verification list for safety surgery and a safety surgery protocol. Twelve judges assessed five variables (Content, Language, Illustration, Layout and Motivation), for consensus on content validation. They evaluated quality of each item, using a rating scale consisting of five levels (1 to 5). RESULTS: Two assessment rounds were done, with a mean content validity index (CVI) of 0.95 and 1.0 and a kappa index of >0.83 and >0.92, respectively. The judges provided positive comments about each phase of the study, most of comments highlights were: choice of very relevant subject matter, excellent quality of the material and the motivation that the material can provide to the target audience. CONCLUSION: The study validated the content of learning technology by general consensus of judges with a high level of concordance among evaluated items. The application was considered adequate for educating students and health professionals about surgical safety. PMID- 30286371 TI - Evaluation of training on palliative care for staff working within a homeless hostel. AB - BACKGROUND: In the UK, many people experiencing homelessness whose health is deteriorating remain in homeless hostels due to few suitable alternative places of care. Hostel staff struggle to support residents with deteriorating health and palliative care services are rarely involved. There is recognition of the need for multiagency working to support this group. OBJECTIVES: To pilot and evaluate the impact of a two-day training course for hostel staff around supporting clients with palliative care needs, and increasing multiagency working. DESIGN: Mixed methods evaluation using pre-and-post training data collection. SETTINGS AND PARTICIPANTS: Frontline staff from two London homeless hostels. METHODS: Staff from two hostels attended a two day training course. Self-perceived confidence in supporting residents with deteriorating health, knowledge of palliative care, openness to discussing deteriorating health and work related stress were assessed at baseline and immediately after training using a novel questionnaire. Qualitative data was collected via focus groups immediately after and three months post-training. RESULTS: Twenty four participants attended at least one day of training, 21 (87%) completed the course. Training was reported to be useful and relevant. Modest improvements in self-perceived work related stress, knowledge, confidence and openness were observed following training. At three months, qualitative data indicated the beginnings of a shift in how palliative care was conceptualised and an increase in knowledge and confidence around supporting residents. Anxiety regarding the role of the hostel in palliative care, the recovery focused ethos of homelessness services and fragmented systems and services presented challenges to establishing changes. CONCLUSIONS: Training can be useful for improving knowledge, confidence, openness and work related stress. Recommendations for implementing changes in how people experiencing homelessness are supported include embedding training into routine practice, promoting multidisciplinary working, incorporating flexibility within the recovery focused approach of services and recognising the need for emotional support for staff. PMID- 30286372 TI - Staff perception of the sustainability of a mature simulation program in nursing and midwifery education: A phenomenological analysis. AB - BACKGROUND: As an established pedagogy for teaching clinical nursing skills, the use of simulation in nursing and midwifery education continues to increase globally. In Australia, government incentives for staff development, capital equipment and scenario provided initial impetus for introducing simulation into nursing programs. However, a mature simulation program requires ongoing investment in staff and resources. Without appropriate commitment from educators and organisations, a likely decline in the quality of simulation activities may have a direct impact on student learning. PURPOSE: This study sought to explore the views and experiences of nursing and midwifery academics involved in delivering a simulation-based education program in a maturation phase. METHOD: In this qualitative study, interpretative phenomenological analysis was used to inform data collection and analysis. Data were collected through semi-structured audio-recorded interviews with 10 faculty staff in a tertiary school of nursing and midwifery. RESULTS: Four main themes related to simulated learning were abstracted from the data: perceptions and reactions, inconsistent customs, pedagogy of simulation-based education, and collateral opportunities. The findings are located within the context of a maturation, rather than introductory, phase of delivering simulation-based education in a tertiary education setting. CONCLUSIONS: A mature simulation program may be undermined by ageing equipment and scenarios, and facilitators whose skills have not been maintained. Existing simulation activities require ongoing organisational support and investment. The development and introduction of minimum competency levels for facilitators and standardised measures of quality in practice are indicated, to improve simulation practice in the education setting. PMID- 30286373 TI - Comparing the effects of traditional lecture and flipped classroom on nursing students' critical thinking disposition: A quasi-experimental study. AB - BACKGROUND: One of the most principal key aims of nursing education is to promote nursing students' and nurses' critical thinking. Therefore, nursing education needs to develop an appropriate curriculum and use effective instructional strategies for critical thinking promotion. Flipped classroom is a teaching method which substitutes individual learning for group learning in a dynamic, interactive environment where the teacher guides students to understand and use concepts. OBJECTIVES: The present study aimed to compare the effects of traditional lecture and flipped classroom on Iranian nursing students' critical thinking disposition. METHODS: This nonequivalent control group pretest-posttest quasi-experimental study was done in 2016 on 85 second-year bachelor's nursing students who had signed up for the Musculoskeletal Medical-Surgical Nursing theoretical training course. Because of their large number, students had been divided at the beginning of the first semester of their four-year program into two 42- and 43-student groups and attended separate theoretical training classes. These two classes were randomly allocated to either a traditional lecture or a flipped classroom group. The instructional strategies in these groups were the traditional lecture and the flipped class strategies, respectively. A demographic questionnaire and Ricketts' Critical Thinking Disposition Inventory were used for data collection. RESULTS: After the intervention, the mean scores of critical thinking disposition and its engagement domain in the flipped class group were significantly higher than the traditional lecture group (P < 0.0001). CONCLUSIONS: This study shows the positive effects of flipped classroom on nursing students' critical thinking disposition. It is recommended that future studies assess the effects of flipped classroom on other nursing education outcomes. PMID- 30286375 TI - Engineering hydrogel viscoelasticity. AB - The aim of this study was to identify a method for modifying the time-dependent viscoelastic properties of gels without altering the elastic component. To this end, two hydrogels commonly used in biomedical applications, agarose and acrylamide, were prepared in aqueous solutions of dextran with increasing concentrations (0%, 2% and 5% w/v) and hence increasing viscosities. Commercial polyurethane sponges soaked in the same solutions were used as controls, since, unlike in hydrogels, the liquid in these sponge systems is poorly bound to the polymer network. Sample viscoelastic properties were characterised using the epsilon-dot method, based on compression tests at different constant strain rates. Experimental data were fitted to a standard linear solid model. While increasing the liquid viscosity in the controls resulted in a significant increase of the characteristic relaxation time (tau), both the instantaneous (Einst) and the equilibrium (Eeq) elastic moduli remained almost constant. However, in the hydrogels a significant reduction of both Einst and tau was observed. On the other hand, as expected, Eeq - an indicator of the equilibrium elastic behaviour after the occurrence of viscoelastic relaxation dynamics - was found to be independent of the liquid phase viscosity. Therefore, although the elastic and viscous components of hydrogels cannot be completely decoupled due to the interaction of the liquid and solid phases, we show that their viscoelastic behaviour can be modulated by varying the viscosity of the aqueous phase. This simple-yet-effective strategy could be useful in the field of mechanobiology, particularly for studying cell response to substrate viscoelasticity while keeping the elastic cue (i.e. equilibrium modulus, or quasi-static stiffness) constant. PMID- 30286374 TI - Nondestructive characterization of bone tissue scaffolds for clinical scenarios. AB - OBJECTIVES: This study aimed to develop a simple and efficient numerical modeling approach for characterizing strain and total strain energy in bone scaffolds implanted in patient-specific anatomical sites. MATERIALS AND METHODS: A simplified homogenization technique was developed to substitute a detailed scaffold model with the same size and equivalent orthotropic material properties. The effectiveness of the proposed modeling approach was compared with two other common homogenization methods based on periodic boundary conditions and the Hills energy theorem. Moreover, experimental digital image correlation (DIC) measurements of full-field surface strain were conducted to validate the numerical results. RESULTS: The newly proposed simplified homogenization approach allowed for fairly accurate prediction of strain and total strain energy in tissue scaffolds implanted in a large femur mid-shaft bone defect subjected to a simulated in-vivo loading condition. The maximum discrepancy between the total strain energy obtained from the simplified homogenization approach and the one obtained from detailed porous scaffolds was 8.8%. Moreover, the proposed modeling technique could significantly reduce the computational cost (by about 300 times) required for simulating an in-vivo bone scaffolding scenario as the required degrees of freedom (DoF) was reduced from about 26 million for a detailed porous scaffold to only 90,000 for the homogenized solid counterpart in the analysis. CONCLUSIONS: The simplified homogenization approach has been validated by correlation with the experimental DIC measurements. It is fairly efficient and comparable with some other common homogenization techniques in terms of accuracy. The proposed method is implicating to different clinical applications, such as the optimal selection of patient-specific fixation plates and screw system. PMID- 30286376 TI - A material modeling approach for the effective response of planar soft tissues for efficient computational simulations. AB - One of the most crucial aspects of biomechanical simulations of physiological systems that seek to predict the outcomes of disease, injury, and surgical interventions is the underlying soft tissue constitutive model. Soft tissue constitutive modeling approaches have become increasingly complex, often utilizing meso- and multi-scale methods for greater predictive capability and linking to the underlying biological mechanisms. However, such modeling approaches are associated with substantial computational costs. One solution is to use effective constitutive models in place of meso- and multi-scale models in numerical simulations but derive their responses by homogenizing the responses of the underlying meso- or multi-scale models. A robust effective constitutive model can thus drastically increase the speed of simulations for a wide range of meso- and multi-scale models. However, there is no consensus on how to develop a single effective constitutive model and optimal methods for parameter estimation for a wide range of soft tissue responses. In the present study, we developed an effective constitutive model which can fully reproduce the response of a wide range of planar soft tissues, along with a method for robust and fast-convergent parameter estimation. We then evaluated our approach and demonstrated its ability to handle materials of widely varying degrees of stiffness and anisotropy. Furthermore, we demonstrated the robutst performance of the meso-structural to effective constitutive model framework in finite element simulations of tri leaflet heart valves. We conclude that the effective constitutive modeling approach has significant potential for improving the computational efficiency and numerical robustness of multi-scale and meso-scale models, facilitating efficient soft tissue simulations in such demanding applications as inverse modeling and growth. PMID- 30286379 TI - Experience of perceived barriers and enablers of safe uninterrupted skin-to-skin contact during the first hour after birth in Uganda. AB - OBJECTIVE: To identify barriers and enablers to conducting safe uninterrupted skin-to-skin contact (SSC) in the first hour after birth in a low-resource setting and to evaluate how health care professionals coped with the identified barriers after completion of an intervention package. DESIGN AND SETTING: A qualitative method using focus-group and individual interviews with health professionals at a governmental hospital in Uganda. PARTICIPANTS: 81 health professionals. INTERVENTIONS: A 6-step intervention package including, amongst other things, showing a DVD on safe uninterrupted SSC following birth and discussing with the professionals what barriers and possibilities there were to changing practice to allow SSC for one hour. MEASUREMENTS AND FINDINGS: The thematic analysis of the intervention interviews yielded the following themes: Perceived barriers including medical events, psychosocial issues and standard midwifery practice; Pragmatic barriers including economic constraints in the hospital and community; Anticipated barriers by staff and families; Enabling events including staff involvement. Most of the barriers involving expenses were not solved. When the mother and infant had to move to the postnatal ward within one hour after birth, there were difficulties in keeping SSC during the transportation, but this obstacle was partly solved. A few mothers (i.e. depressed and/or adolescent) were considered to be unwilling to keep the infant skin-to-skin; this difficulty was not solved. Practising SSC led the participants to find advantages such as reduced work load and positive effects on pain during suturing. CONCLUSIONS: SSC following birth was shown to be applicable and accepted by the health professionals. The involvement of professionals had clinical implications, such as initiatives to broadcast the message of SSC by radio to the community and introduce SSC to women having a Caesarean section. PMID- 30286377 TI - Calorie restriction attenuates hypertrophy-induced redox imbalance and mitochondrial ATP-sensitive K+ channel repression. AB - Oxidative stress has been implicated in the pathogenesis of cardiac hypertrophy and associated heart failure. Cardiac tissue grows in response to pressure or volume overload, leading to wall thickening or chamber enlargement. If sustained, this condition will lead to a dysfunctional cardiac tissue and oxidative stress. Calorie restriction (CR) is a powerful intervention to improve health and delay aging. Here, we investigated whether calorie restriction in mice prevented isoproterenol-induced cardiac hypertrophy in vivo by avoiding reactive oxygen species (ROS) production and maintaining antioxidant enzymatic activity. Additionally, we investigated the involvement of mitochondrial ATP-sensitive K+ channels (mitoKATP) in cardiac hypertrophy. CR was induced by 40% reduction in daily calorie ingestion. After 3 weeks on CR or ad libitum (Control) feeding, Swiss mice were treated intraperitoneally with isoproterenol (30 mg/kg per day) for 8 days to induce hypertrophy. Isoproterenol-treated mice had elevated heart weight/tibia length ratios and cardiac protein levels. These gross hypertrophic markers were significantly reduced in CR mice. Cardiac tissue from isoproterenol treated CR mice also produced less H2O2 and had lower protein sulfydryl oxidation. Additionally, calorie restriction blocked hypertrophic-induced antioxidant enzyme (catalase, superoxide dismutase and glutathione peroxidase) activity repression during cardiac hypertrophy. MitoKATP opening was repressed in isolated mitochondria from hypertrophic hearts, in a manner sensitive to calorie restriction. Finally, mitoKATP inhibition significantly blocked the protective effects of calorie restriction. Altogether, our results suggest that CR improves intracellular redox balance during cardiac hypertrophy and prevents this process in a mechanism involving mitoKATP activation. PMID- 30286380 TI - Efficacy of a multidisciplinary approach on postoperative morbidity and mortality of elderly patients with hip fracture. AB - STUDY OBJECTIVE: We evaluated the efficacy of a multidisciplinary approach to reduce postoperative complications and 1-year mortality in patients, undergoing hip fracture surgery and the impact of surgical delay on mortality. DESIGN: A non randomized intervention study with a historical control group (CG). SETTING: During the hospital stay of patients undergoing hip fracture surgery and subsequent follow-up during 12 months post-discharge. PATIENTS: 240 patients undergoing hip fracture surgery were included in the CG. 272 patients were included in the intervention group (IG). INTERVENTIONS: CG patients received the standard care given at our hospital. Patients in the IG received a new model of multidisciplinary approach to care. MEASUREMENTS: The following variables were collected: study group, age, gender, ASA physical status, comorbidity, type of fracture, type of anaesthesia, surgical delay, postoperative complications, hospital stay, destination after discharge and postoperative mortality. MAIN RESULTS: 512 patients (CG = 240; IG = 272). Mean age was 83.8 years in CG and 84.9 years in IG. Patients in the IG had a worse health status according to ASA (III-IV: 68.8% vs 51.7%; p < 0.001) and took more drugs (p < 0.001). Surgery was performed within 48 h of admission in 55.1% of patients of the IG (38.3% CG; p < 0.001). Incidence of postoperative complications (67.3% IG vs 76.2% CG p = 0.025) and hospital stay was shorter in the IG (p < 0.001). A surgical delay of >48 h (HR = 0.61; CI95%: 0.42-0.88) and allocation to the IG (HR = 0.64; CI95%: 0.44 0.93) were the protective factors for mortality. CONCLUSIONS: The multidisciplinary approach could be associated with a decrease in postoperative complications, hospital stay and mortality. Surgical delay may not increase the risk of mortality. The main objective in the management of these patients should be the optimization of their general health status before surgery rather than surgical delay. PMID- 30286381 TI - Intraindividual sleep variability and its association with insomnia identity and poor sleep. AB - OBJECTIVE: Insomnia identity refers to the conviction that one has insomnia, which can occur independently of poor sleep. Night-to-night variability in sleep (termed intraindividual variability [IIV]) may contribute to insomnia identity yet remain undetected via conventional mean analyses. This study compared sleep IIV across four subgroups: noncomplaining good sleepers (NG), complaining poor sleepers (CP), complaining good sleepers (CG), and noncomplaining poor sleepers (NP). METHODS: This study analyzed 14 days of sleep diary data from 723 adults. Participants were classified according to presence/absence of a sleep complaint and presence/absence of poor sleep. A 2 * 2 multivariate analysis of covariance (MANCOVA) was performed to explore differences on five measures of sleep IIV: intraindividual standard deviation in total sleep time (iSD TST), sleep onset latency (iSD SOL), wake after sleep onset (iSD WASO), number of nightly awakenings (iSD NWAK), and sleep efficiency (iSD SE). RESULTS: MANCOVA revealed significant main effects of poor sleep, sleep complaint, and their interaction on sleep IIV. Poor sleepers exhibited greater IIV across all sleep parameters compared to good sleepers. Similarly, individuals with a sleep complaint exhibited greater IIV compared to individuals with no complaint. The interaction revealed that iSD SOL was significantly greater among CP than NP, and iSD NWAK was significantly greater among CG than NG. CONCLUSIONS: Greater night-to-night variability in specific sleep parameters was present among complaining versus noncomplaining sleepers in good and poor sleep subgroups. These findings suggest certain aspects of sleep consistency may be salient for treatment-seeking individuals based on their quantitative sleep status. PMID- 30286378 TI - Common gut microbial metabolites of dietary flavonoids exert potent protective activities in beta-cells and skeletal muscle cells. AB - Flavonoids are dietary compounds with potential anti-diabetes activities. Many flavonoids have poor bioavailability and thus low circulating concentrations. Unabsorbed flavonoids are metabolized by the gut microbiota to smaller metabolites, which are more bioavailable than their precursors. The activities of these metabolites may be partly responsible for associations between flavonoids and health. However, these activities remain poorly understood. We investigated bioactivities of flavonoid microbial metabolites [hippuric acid (HA), homovanillic acid (HVA), and 5-phenylvaleric acid (5PVA)] in primary skeletal muscle and beta-cells compared to a native flavonoid [(-)-epicatechin, EC]. In muscle, EC was the most potent stimulator of glucose oxidation, while 5PVA and HA simulated glucose metabolism at 25 MUM, and all compounds preserved mitochondrial function after insult. However, EC and the metabolites did not uncouple mitochonndrial respiration, with the exception of 5PVA at10 MUM. In beta-cells, all metabolites more potently enhanced glucose-stimulated insulin secretion (GSIS) compared to EC. Unlike EC, the metabolites appear to enhance GSIS without enhancing beta-cell mitochondrial respiration or increasing expression of mitochondrial electron transport chain components, and with varying effects on beta-cell insulin content. The present results demonstrate the activities of flavonoid microbial metabolites for preservation of beta-cell function and glucose utilization. Additionally, our data suggest that metabolites and native compounds may act by distinct mechanisms, suggesting complementary and synergistic activities in vivo which warrant further investigation. This raises the intriguing prospect that bioavailability of native dietary flavonoids may not be as critical of a limiting factor to bioactivity as previously thought. PMID- 30286382 TI - Association between sleep duration during pregnancy and gestational diabetes mellitus: a meta-analysis. AB - OBJECTIVE: Sleep is critical for glucose metabolism. Pregnant women often have sleep disturbances and extreme sleep duration. Investigations of the relationship between sleep duration during pregnancy and gestational diabetes mellitus (GDM) have reported inconsistent results. The present study aimed to meta-analyze the relationship between sleep duration during pregnancy and GDM risk. METHODS: We performed a systematic search of the PubMed, ISI Web of Science, and PsycINFO databases for studies that were published up to October 2017, that reported associations between sleep duration during pregnancy and GDM risk. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated as the effect sizes for all studies. Heterogeneity and potential publication biases were assessed. RESULTS: A total of 4366 papers were retrieved, among which seven studies assessed the relationship between sleep duration during pregnancy and GDM development. The seven articles included 18,203 subjects at baseline and 1294 GDM cases during follow-up. Compared to normal sleep duration, extreme sleep duration during early and middle pregnant stages had a close relationship with GDM based upon pooled data from prospective and cross-sectional studies. Prospective results showed that long sleep duration during pregnancy was a risk factor for GDM, but not short sleep duration. Publication biases were found when analyzing the relationship between extreme sleep duration and GDM. CONCLUSIONS: Extreme sleep duration during pregnancy is closely associated with GDM. Moreover, long but not short sleep duration can predict the risk of developing GDM. These findings remind us of the importance of sleep duration control during pregnancy and help optimize early strategies for the prevention of GDM. PMID- 30286383 TI - Last night's sleep in relation to academic achievement and neurocognitive testing performance in adolescents with and without ADHD. AB - OBJECTIVES/BACKGROUND: Objectives were to (1) examine previous night's sleep in relation to next day performance on standardized academic achievement and neurocognitive assessments in adolescents, and (2) explore whether previous night's sleep is differentially associated with testing performance for adolescents with and without attention-deficit/hyperactivity disorder (ADHD). PARTICIPANTS/METHODS: Participants were 300 adolescents (ages 12-14 years; 55% male). Approximately half (53.6%) were diagnosed with ADHD. Adolescents provided ratings of their previous night's sleep quality, sleep duration, and number of night wakings and were administered standardized tests of processing speed and working memory, as well as word reading, numerical operations, and math fluency academic achievement. RESULTS: In analyses controlling for sex, race, medication use, time of testing, and ADHD group status, more night wakings the previous night were associated with significantly lower numerical operations and math fluency achievement scores and marginally lower working memory scores. Previous night's sleep was not associated with processing speed or reading achievement. ADHD status did not moderate sleep in relation to academic/neurocognitive performance. Participants reporting >=2 night wakings the previous night had slightly over half a standard deviation lower scores on average compared to participants reporting 0 night wakings. CONCLUSIONS: This preliminary study suggests that previous night's wakings are associated with poorer mathematics performance the next day, regardless of ADHD status. This may be due to the detrimental effect of interrupted and fragmented sleep on attention and executive control. These findings have implications for clinicians and educators when considering contextual factors that may impact academic and neurocognitive testing performance. PMID- 30286384 TI - Assessment of change in restless legs syndrome symptoms during the acute drug withdrawal period. PMID- 30286385 TI - Using actigraphy to assess sleep and wake rhythms of narcolepsy type 1 patients: a comparison with primary insomniacs and healthy controls. AB - OBJECTIVE/BACKGROUND: It has been shown that actigraphy may have a discriminant function (DS) for the diagnosis of narcolepsy type 1 patients (NT1), based on a combination of nighttime and daytime parameters. Here, we aimed to test those findings using another actigraph model with a different clinical sample as control (ie, primary insomniacs, PI), carrying out a secondary analysis of previously collected data. PATIENTS/METHODS: The study sample consisted of 13 NT1 (nine females; mean age 39.38 +/- 11.48), 13 PI (nine females; mean age 38.69 +/- 10.72) and 13 Healthy Controls (HC) (nine females; mean age 38 +/- 10.77). Participants wore the Actiwatch AW64 (Cambridge Neurotechnology Ltd, Cambridge, UK) around the non-dominant wrist for seven consecutive days. RESULTS: Significant differences between groups were observed with a higher number of episodes of wakefulness (wake bouts, WB) in PI than HC, a higher fragmentation index (FI) in NT1 than HC and PI, a higher duration of the longest nap (LNAP) in NT1 than HC and PI and higher DS in PI and NT1 than HC. A new DS (NDS), with LNAP and FI as independent variables, was proposed; which was higher in NT1 than HC and PI. CONCLUSIONS: The present study confirms that actigraphy discriminates NT1 from HC. However, considering PI, a new discriminant function NDS which takes into account LNAP and FI is better for this actigraph model. PMID- 30286387 TI - The genetic makings of South Asia. AB - South Asia is home for more than a billion people culturally structured into innumerable groups practicing different levels of endogamy. Linguistically South Asia is broadly characterized by four major language families which has served as access way for disentangling the genetic makings of South Asia. In this review we shall give brief account on the recent developments in the field. Advances are made in two fronts simultaneously. Whole genome characterisation of many extant South Asians paint the picture of the genetic diversity and its implications to health-care. On the other hand ancient DNA studies, which are finally reaching South Asia, provide new incites to the demographic history of the subcontinent. Before the spread of agriculture, South Asia was likely inhabited by hunter gatherer groups deriving much of their ancestry from a population that split from the rest of humanity soon after expanding from Africa. Early Iranian agriculturalists mixing with these local hunter-gatherers probably formed the population that flourished during the blossoming of the Indus Valley Civilisation. Further admixture with the still persisting HG groups and population(s) from the Eurasian Steppe, formed the two ancestral populations (ANI and ASI), the north-south mixing pattern of whom is known today as the 'Indian Cline'. Studies on natural selection in South Asia have so far revealed strong signals of sweeps that are shared with West Eurasians. Future studies will have to fully unlock the aDNA promise for South Asia. PMID- 30286386 TI - Disruption of superficial white matter in the emotion regulation network in bipolar disorder. AB - Bipolar disorder (BD) is characterized by emotion dysregulation and involves changes in the gray matter (GM) and white matter (WM). Although previous diffusion tensor imaging (DTI) studies reported changes in the diffusion properties of the deep WM (DWM) in BD patients, the diffusion properties of the superficial WM (SWM) are rarely investigated. In this study, we tried to determine whether the diffusion parameters of the SWM were altered in BD patients compared to controls and whether the changes were associated with the disrupted emotion regulation of the BD patients. We collected DTI data from 37 BD patients and 42 gender- and age-matched healthy controls (HC). Using probabilistic tractography, we defined a population-based SWM mask based on all the subjects. After performing the tract-based spatial statistical (TBSS) analyses, we identified the SWM areas in which the BD patients differed from the controls. This study showed significantly reduced fractional anisotropy in the SWM (FASWM) in the BD patients compared to the HC in the bilateral dorsolateral prefrontal cortex (dlPFC), ventrolateral prefrontal cortex (vlPFC), medial prefrontal cortex (mPFC), and the left parietal cortex. Moreover, compared to the controls, the BD patients showed significantly increased mean diffusivity (MDSWM) and radial diffusivity (RDSWM) in the SWM in the right frontal cortex. This study presents altered cortico-cortical connections proximal to the regions related to the emotion dysregulation of BD patients, which indicated that the SWM may serve as the brain's structural basis underlying the disrupted emotion regulation of BD patients. The disrupted FASWM in the parietal cortex may indicate that the emotion dysregulation in BD patients is related to the cognitive control network. PMID- 30286388 TI - Rare atlas fracture detected using postmortem computed tomography: A case report. AB - We report the autopsy of a traffic accident victim with a rare atlas fracture. The deceased was 52-year-old man found dead on the road because of a traffic accident. We performed a postmortem computed tomography and an autopsy on the body. The sagittal reformation image of postmortem computed tomography showed a vertically separated anterior arch of atlas, suggesting a "horizontal fracture." Therefore, we assumed that cervical hyperextension may have been one of the forces that affected him during the accident. Minor spinal cord injury was also noted. In this case, postmortem computed tomography played an important role in detecting the spinal cord injury, considering the mechanism of the traffic accident, and supported the autopsy. PMID- 30286389 TI - Developmental evidence for a link between the inherence bias in explanation and psychological essentialism. AB - The assumption that natural and social categories have deeper "essences" is a fundamental feature of the conceptual system, with wide-ranging consequences for behavior. What are the developmental origins of this assumption? We propose that essentialism emerges in part from a bias in the process of generating explanations that leads reasoners to overuse inherent or intrinsic features. Consistent with this proposal, the inherence bias in 4-year-olds' explanations predicted the strength of their essentialist beliefs (Study 1; N = 64), and manipulations of the inherence bias in 4- to 7-year-olds (Studies 2 and 3; N = 112 each) led to subsequent changes in the essentialist beliefs of children who attended to the manipulation. These findings contribute to our understanding of the origins of essentialism. PMID- 30286390 TI - Convulsive seizures and EEG spikes after lateral fluid-percussion injury in the rat. AB - The rat lateral fluid-percussion injury (FPI) model has been used extensively to study post-traumatic epilepsy (PTE). Epidemiological studies have reported that the risk of PTE is higher after more severe injury. Adult, male Wistar rats subjected to different atmospheric pressures of injury during FPI showed great variability in injury severity when functional behavior was determined based on the Neurological Severity Score (NSS) assessment. When NSS was used to select rats with the most severe FPI-induced brain injury, 63% of rats experienced at least one convulsive seizure 2-5 weeks after FPI. This same cohort of rats (i.e., selected for severe TBI based on NSS) were significantly more susceptible to PTZ induced seizures compared to sham controls. Video/EEG recordings from a second cohort of rats with severe FPI-induced injury (based on NSS) showed a similar incidence and frequency of spike wave discharges between rats with severe TBI and sham controls. However, the rate of isolated EEG spikes was greater in rats with severe FPI-induced injury compared to sham controls. These data suggest that convulsive seizures can be obtained in FPI-treated rats when NSS is used as an inclusion criterion to select rats with severe injury. Furthermore, although spike-wave discharges were equally prevalent in rats with severe FPI and sham controls, spontaneous spikes were more prevalent in the rats with severe FPI. PMID- 30286391 TI - Diagnosis switching and outcomes in a cohort of patients with potential epilepsy with myoclonic-atonic seizures. AB - INTRODUCTION: There is overlap in the electroclinical features of many childhood epilepsy syndromes, especially those presenting with multiple seizure types, such as epilepsy with myoclonic-atonic seizures (EMAS) and Lennox-Gastaut syndrome (LGS). This study aimed to determine the frequency of diagnosis switching and the factors influencing epilepsy syndrome diagnosis in a cohort of children with possible EMAS, as well as to explore the relationship between epilepsy syndrome diagnoses, key electroclinical features, and clinically relevant outcomes. METHODS: This is a cross-sectional retrospective chart review of children treated at the Children's Hospital of Colorado with a potential diagnosis of EMAS. RESULTS: There were 77 patients that met eligibility criteria, including 39% (n = 30) with an initial diagnosis of EMAS and 74% (n = 57) with a final diagnosis of EMAS. On average, for the 65% of patients who received more than one epilepsy diagnosis, the first, second, and third diagnoses were received within one year, three years, and ten years after epilepsy onset, respectively. Final diagnosis was significantly related to obtaining at least a six-month period of seizure freedom, p = 0.03. Classic LGS traits, including paroxysmal fast activity, slow spike-and-wave, and tonic seizures were present in 50% of the overall cohort, although a minority of these patients had a final diagnosis of LGS. However, the presence of more LGS traits was associated with a higher likelihood of ongoing seizures. Adjusted for age of epilepsy onset, seizure freedom was half as likely for every additional LGS trait observed (0.49[0.31, 0.77], p = 0.002). CONCLUSION: Current epilepsy syndrome classification has reduced applicability due to overlapping features. This results in diagnosis switching and limited prognostic value for patients with an overlapping clinical phenotype. Future studies should attempt to stratify patients based not only on epilepsy syndrome diagnosis, but also on the presence of various electroclinical traits to more accurately predict outcome.

AB - We have performed quantum-based molecular dynamics (MD) simulations in conjunction with multiscale shock technique (MSST) to investigate the initial chemical processes and the anisotropy of shock sensitivity of the RDX under shock loading applied along the different directions. The results show that there is a difference between x (or y)-direction and z-direction in the response to a shock wave velocity of 12 km/s. It was shown that detonation temperature and pressure in the z-direction lags behind that of x-direction (or y-direction). Moreover, from the time evolution of the population of various key fragments, we also observe that along with z-direction significantly later than that of x (or y) direction, which the reaction rate is also slower. Thus, we draw a conclusion that sensitive for shock propagation along x or y-direction, but less sensitive for shock propagation along z-direction.

AB - Density functional theory calculations are performed to compare catalytic oxidation of CO molecule over Al- and P-embedded hexagonal boron nitride nanosheet (h-BN). It is found that the Al and P adatom can be stably anchored on the boron-vacancy site of h-BN, as evidenced by a relatively large adsorption energy and charge-transfer value. According to our findings, the oxidation of CO over these surfaces proceeds via the Langmuir-Hinshelwood mechanism, followed by the elimination of the remaining atomic O by another CO molecule. Meanwhile, the stronger adsorption of O2 than CO avoids poisoning of the active site of both surfaces. The results of the present study indicate that Al-doped h-BN exhibits higher catalytic activity for CO oxidation than P-doped one, which may provide a valuable guidance on design metal-free catalysts to remove toxic CO molecules. PMID- 30286394 TI - Combined dilute hydrochloric acid and alkaline wet oxidation pretreatment to improve sugar recovery of corn stover. AB - Two-stage dilute hydrochloric acid (DA)/aqueous ammonia wet oxidation (AWO) pretreatment was used to recover the sugars of corn stover. The morphology characterizations of samples were detected by SEM, BET and SXT. The results showed that DA-AWO process demonstrated a positive effect on sugar recovery compared to AWO-DA. 82.8% of xylan was recovered in the first stage of DA-AWO process at 120 degrees C for 40 min with 1 wt% HCl. The second stage was performed under relative mild reaction conditions (130 degrees C, 12.6 wt% ammonium hydroxide, 3.0 MPa O2, 40 min), and 86.1% lignin could be removed. 71.5% of glucan was achieved with a low enzyme dosage (3 FPU.g-1) in the following enzymatic hydrolysis. DA-AWO pretreatment was effective due to its sufficient hydrolysis of hemicellulose in the first stage and remarkably removal of the lignin in the second stage, resulting in high sugar recovery with a low enzyme dosage. PMID- 30286396 TI - Emotion regulation difficulties and social control correlates of smoking among pregnant women trying to quit. AB - Approximately 15% of US women currently smoke during pregnancy. An important step toward providing effective smoking cessation interventions during pregnancy is to identify individuals who are more likely to encounter difficulty quitting. Pregnant smokers frequently report smoking in response to intrapersonal factors (e.g., negative emotions), but successful cessation attempts can also be influenced by interpersonal factors (i.e., influence from close others). This study examined the association between emotion regulation difficulties, positive and negative social control (e.g., encouragement, criticism), and smoking cessation-related variables (i.e., smoking quantity, withdrawal symptoms) among pregnant smokers. Data were drawn from the pretreatment wave of a smoking cessation trial enrolling low-income pregnant women who self-reported smoking in response to negative affect (N = 73). Greater emotion regulation difficulties were related to greater smoking urges (b = 0.295, p = .042) and withdrawal symptoms (b = 0.085, p = .003). Additionally, more negative social control from close others was related to fewer smoking days (b = -0.614, p = .042) and higher smoking abstinence self-efficacy (b = 0.017, p = .002). More positive social control from close others interacted with negative affect smoking (b = -0.052, p = .043); the association between negative affect smoking and nicotine dependence (b = 0.812, p < .001) only occurred at low levels of positive social control. Findings suggest that emotion regulation difficulties may contribute to smoking during pregnancy by exacerbating women's negative experiences related to smoking cessation attempts. Negative social control was related to lower smoking frequency and greater confidence in quitting smoking, suggesting that it may assist pregnant smokers' cessation efforts. Positive social control buffered women from the effects of negative affect smoking on nicotine dependence. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01163864.

AB - A multicomponent nanocatalyst system was fabricated for the transfer hydrogenation of nitrile compounds. This catalyst system contains palladium, copper, and iron, which are supported on the magnetite nanospheres, and the loading of palladium could be at the parts per million level. Palladium and copper contribute to the transformation of nitrile, and the product distribution highly depends on the alloying of Fe to Cu. The nitriles could be converted to primary amine by the Pd-Cu catalyst in the absence of Fe, whereas in the presence of Fe the products are secondary amines with high selectivity. This could be attributed to the electronic modulation of iron to copper. A variety of nitriles have been transformed to the corresponding primary or secondary amines with high selectivity, and the TOF reaches 2,929 hr-1 for Pd. Furthermore, the catalyst could be recycled by an external magnetic field and reused five times without severe activity loss. PMID- 30286397 TI - Phenotypic and genetic relationship between BMI and cigarette smoking in a sample of UK adults. AB - In addition to the health hazards posed individually by cigarette smoking and obesity, the combination of these conditions poses a particular impairment to health. Genetic factors have been shown to influence both traits and, to understand the connection between these conditions, we examined both the observed and genetic relationship between adiposity (an electrical impedance measure of body mass index (BMI)) and cigarettes smoked per day (CPD) in a large sample of current, former, and never smokers in the United Kingdom. In former smokers, BMI was positively associated with cigarettes formerly smoked; further, the genetic factors related to a greater number of cigarettes smoked were also responsible for a higher BMI. In current smokers, there was a positive association between BMI and number of cigarettes smoked, though this relationship did not appear to be influenced by similar genetic factors. We found a positive genetic relationship between smoking in current/former smokers and BMI in never smokers (who would be unmarred by the effects of nicotine). In addition to CPD, in current smokers, we looked at two variables, time from waking to first cigarette and difficulty not smoking for a day, that may align better with cigarette and food 'craving.' However, these smoking measures provided mixed findings with respect to their relationship with BMI. Overall, the positive relationships between the genetic factors that influence CPD in smokers and the genetic factors that influence BMI in former and never smokers point to common biological influences behind smoking and obesity. PMID- 30286398 TI - Effect of coexisting ions on Cr(VI) adsorption onto surfactant modified Auricularia auricula spent substrate in aqueous solution. AB - In this paper, the effect of coexisting cations and anions on Cr(VI)(in the form of Cr2O72-) adsorption onto Auricularia auricula spent substrate (AASS) modified by cetyl trimethyl ammonium bromide (CTAB) was investigated in batch adsorption experiment. The Cr(VI) adsorption capacity of 9.327 mg/g, obtained at pH 3.0, 303 K, adsorbent dosage of 2 g/L, initial Cr(VI) concentration of 20 mg/L, rotational speed of 150 r/min for 120 min, was decreased in the presence of coexisting cations and anions, among which Pb2+ and PO43- affected most by 21.79% and 12.43%, respectively. XRD, XPS and FTIR detection found that coexisting Pb2+ and PO43- would not only interfere Cr(VI) to form crystals and reduce to Cr(III), but also compete with Cr(VI) for oxygen-containing and amino groups to form Pb-O and P-NH2, respectively. In addition, the single Cr(VI) adsorption fitted with Langmuir isotherm model, while the competitive adsorption was well described by Freundlich isotherm model. Both single adsorption and competitive adsorption were in line with the pseudo-second-order kinetic model. PMID- 30286399 TI - LAP it up, fuzz ball: a short history of LC3-associated phagocytosis. AB - LC3-associated phagocytosis (LAP) exists at the crossroads of the two evolutionary pathways of phagocytosis and autophagy. When a phagocyte engulfs an extracellular particle that engages receptor signaling, components of the autophagy machinery and Rubicon are recruited to the cargo-containing phagosome or LAPosome. Formation of the LAPosome is critical for both cargo clearance as well as mediating the proper signaling cascade. Globally, LAP functions as an immunosuppressive mechanism, as LAP deficiency often results in hyperinflammation. As defects in the autophagy machinery have been long associated with aberrant immune responses and autoimmune disorders, it is vital that we now revisit these associations with forms of non-canonical autophagy, like LAP, in mind. PMID- 30286400 TI - Open path incoherent broadband cavity-enhanced measurements of NO3 radical and aerosol extinction in the North China Plain. AB - We describe the observation of the NO3 radical using an incoherent broadband cavity-enhanced absorption spectrometer in an open-path configuration (OP IBBCEAS) in a polluted summer environment in continental China. The instrument was installed 17 m above the ground at the top of a residential complex near the CAREBeijing-NCP 2014 site in Wangdu, Hebei province, about 200 km southwest of Beijing over the period 28 to 30 June 2014. The separation between the transmitter and receiver components of the instrument was 335 cm and the effective pathlength in clean reference air was ~3.4 km. NO3 was detected above the detection limit on all three nights when the instrument was operational. The maximum mixing ratio measured was ~175 pptv with a detection sensitivity of ~36 pptv for measurements with an average acquisition time of 10 min. While most extractive instruments try to avoid interferences arising from aerosol extinction, the open path configuration has advantages owing to its ability to detect trace gases even in the presence of aerosol loading. Moreover, concurrent retrieval of aerosol optical extinction is possible from analysis of the absorption magnitude of the oxygen B-band at 687 nm. The experimental setup, its calibration, data acquisition, and analysis procedure are discussed, and the results presented here demonstrate the sensitivity and specificity that can be achieved at high spatial and temporal resolution using the novel configuration of IBBCEAS in the open path. PMID- 30286401 TI - Patient views regarding the impact of hydrotherapy on critically ill ventilated patients: A qualitative exploration study. AB - BACKGROUND: Intensive Care Unit Acquired Weakness can be mitigated by early activity and progressive mobilization. Hydrotherapy enables patients to work on their recovery in a very early stage. This may lead to higher levels of self efficacy, subsequently higher activity-rates and faster functional recovery. Hydrotherapy might positively affect the regaining of control, hope and trust. Our aim is to explore patient perspective regarding the impact of hydrotherapy on critically ill ventilated patients. METHODS: This qualitative exploration study adopted an interpretative phenomenological approach using in-depth, face to face, semi-structured interviews. Questions covered: pre-admission physical activity, perception of hydrotherapy, affection to water, positive and negative experiences and feelings towards the recovery process. Interviews were analyzed using thematic analysis. RESULTS: Twelve patients were enrolled, of which eight could be interviewed. After analyzing, five main themes were found: experiencing consequences of critical illness, feeling safe in the water, being able to move, positive experiences relating to hydrotherapy and experiencing a turning point. CONCLUSIONS: Hydrotherapy seemed to help patients regain control and belief in their recovery. Patients experienced exercising in water as a turning point in their recovery process. This study encourages to continue providing hydrotherapy to critically ill ventilated patients and may stimulate future research. PMID- 30286402 TI - Lower serum kallistatin level is associated with 28-day mortality in patients with septic shock. AB - PURPOSE: Investigation for whether serum levels of kallistatin, vascular cell adhesion molecule-1 (VCAM-1), and E-selectin are associated with outcomes in patients with septic shock MATERIAL AND METHODS: Biomarker levels were measured using blood samples from patients with septic shock at admission, 24 h, and 72 h and from healthy volunteers. The primary outcome was 28-day mortality. RESULTS: Fifty-eight survivors, fourteen non-survivors, and six healthy volunteers were enrolled. Serum kallistatin level was lower and serum VCAM-1 and E-selectin levels were higher in patients at admission compared with healthy volunteers. Serum kallistatin levels were higher in survivors compared with non-survivors at all time points (4.4 MUg/mL [2.9-6.1] vs. 2.5 MUg/mL [2.1-5.0], P = 0.019 at admission; 4.3 MUg/mL [3.3-5.2] vs. 3.2 MUg/mL [2.2-3.8], P = 0.004 at 24 h; 3.1 MUg/mL [2.5-4.2] vs. 2.3 MUg/mL [1.7-3.1], P = 0.012 at 72 h), while VCAM-1 and E selectin levels showed no difference. In the multivariable analysis, serum kallistatin level at 24 h was independently associated with 28-day mortality (OR, 0.29; 95% CI, 0.08-0.69, P = 0.024). CONCLUSIONS: Lower serum kallistatin level at 24 h was independently associated with 28-day mortality in patients with septic shock. PMID- 30286403 TI - Validation of The Critical-care Pain Observation Tool (CPOT) for the detection of oral-pharyngeal pain in critically ill adults. AB - OBJECTIVE: Mechanically ventilated patients experience pain at rest and during daily care procedures. Our objective was to test the reliability and validity of the Critical-Care Pain Observation Tool (CPOT) to detect oral-pharyngeal pain in intubated and tracheostomised adults during routine oral care procedures. MATERIALS AND METHODS: Two trained research team members independently observed patients during two non-painful (rest and gentle touch) and three potentially painful (oral suctioning, tooth brushing, and swabbing with a sponge toothette) procedures. Conscious patients were asked if they experienced pain during each procedure (yes/no) and to rate their pain intensity on a 0 to 10 numeric rating scale. RESULTS: A total of 98 patients, primarily intubated (92.9%) and male (63.3%) participated. Criterion validation was supported by patient self-report of pain during tooth brushing (AUC=.80; P<0.5) and oral suction (AUC=.72; P<0.3) but not for oral swabbing (AUC=.68; P=0.16). Discriminative validation was demonstrated for all oral care procedures compared to rest (P<.001). Intra-class correlation coefficients between raters ranged from .78 to .91 (P<.001) for total CPOT scores, indicating excellent inter-rater reliability. CONCLUSIONS: The CPOT is reliable and valid for the detection of oral-pharyngeal pain during oral care procedures indicated as painful by critically ill adults. PMID- 30286404 TI - Effect of drought stress on metabolite adjustments in drought tolerant and sensitive thyme. AB - Drought is one of the most important threats to plants and agriculture; therefore, understanding of the mechanism of drought tolerance is crucial for breeding of drought tolerant plants. Here, we assessed effects of four levels of drought (90%, 55%, 40% and 25% FC) on some physiological criteria and metabolite adjustment of two different drought-responsive thyme plants (Thymus vulgaris as drought sensitive and T. Kotschyanus as drought tolerant species), using 1H-NMR. Among three physiological parameters and 18 identified metabolites, species * treatment effects were significant (P <= 0.01) for leaf temperature, acetic acid, citric acid, fumaric acid, malic acid, succinic acid, fructose, sucrose and serine. RWC, chlorophyll and carotenoids content, glucose, alanine and choline were affected by simple effects of species and treatment. Correlation analysis revealed that there is a different correlation between physiological parameters and metabolites in both species. This analysis also revealed that, by ignoring the correlation between malic acid and succinic acid in T. vulgaris, there was no significant correlation between TCA intermediate in both species. According to results, sugars, amino acid and energy metabolism were affected by drought and, among them, TCA intermediates had more alternation in two studied species so, this cycle and its intermediates probably have more prominent role than other identified metabolites in the induction of drought tolerance. PMID- 30286405 TI - Toxic effects of the fungicide tebuconazole on the root system of fusarium infected wheat plants. AB - The study investigates toxic effects of the fungicide tebuconazole (TEB) on Fusarium-infected wheat (Triticum aestivum) plants based on the morphological characteristics of root apices and changes in the integrated parameters of redox homeostasis, including the contents of free proline and products of peroxidation of proteins (carbonylated proteins, CP) and lipids (malondialdehyde, MDA) in roots. In two-day-old wheat sprouts infected by Fusarium graminearum, the levels of proline, CP, and border cells of root apices are higher than in roots of uninfected sprouts by a factor of 1.4, 8.0, and 3, respectively. The triazole fungicide tebuconazole (TEB) at the concentrations of 0.01, 0.10, and 1.00 MUg ml 1 of medium causes a dose-dependent decrease in the number of border cells. The study of the effects of TEB and fusarium infection on wheat plants in a 30-day experiment shows that the effect of the fungicide TEB on redox homeostasis in wheat roots varies depending on the plant growth stage and is significantly different in ecosystems with soil and plants infected by Fusarium phytopathogens. The study of the morphology of root apices shows that the toxic effects of TEB and fusarium infection are manifested in the destructive changes in root apices and the degradation of the root tip mantle. PMID- 30286406 TI - Salinity effect on Cuscuta campestris Yunck. Parasitism on Arabidopsis thaliana L. AB - Stem holoparasitic flowering plants of the genus Cuscuta are globally distributed invasive species and agricultural pests. The present research represents the combined effect of salt stress (e.g. abiotic stress) and Cuscuta campestris infection (e.g. biotic stress) on the model host plant Arabidopsis thaliana and the response of the parasite to salinity. The response of these parasites to abiotic stress conditions including salinity is poorly studied. Arabidopsis plants were continuously irrigated with 0, 50 and 150 mM NaCl and subjected to C. campestris infection. The influence of both abiotic and biotic stresses on the major osmoprotectant L-proline and three antioxidant enzymes - catalase, superoxide dismutase and guaiacol peroxidase, was assessed in both the parasite and the host plant. All four biochemical markers were differentially affected by stress, showing that the influence of C. campestris parasitism and its interaction with salinity is mostly in the site of infection (direct response) and also in roots (indirect vertical response) rather than on non-infected leaves of infected plants (indirect horizontal response). Despite its absence of soil contact, C. campestris was also significantly affected by salinity (indirect response). The mutual adaptation of the parasite-host pair to salinity slightly altered the regular response to abiotic stress of A. thaliana, but no detrimental additive effect of biotic and abiotic stress was observed. PMID- 30286407 TI - Rejuvenation of plasticity in the brain: opening the critical period. AB - Cortical circuits are particularly sensitive to incoming sensory information during well-defined intervals of postnatal development called 'critical periods'. The critical period for cortical plasticity closes in adults, thus restricting the brain's ability to indiscriminately store new sensory information. For example, children acquire language in an exposure-based manner, whereas learning language in adulthood requires more effort and attention. It has been suggested that pairing sounds with the activation of neuromodulatory circuits involved in attention reopens this critical period. Here, we review two critical period hypotheses related to neuromodulation: cortical disinhibition and thalamic adenosine. We posit that these mechanisms co-regulate the critical period for auditory cortical plasticity. We also discuss ways to reopen this period and rejuvenate cortical plasticity in adults. PMID- 30286408 TI - The core promoter controls basal and inducible expression of duck retinoic acid inducible gene-I (RIG-I). AB - Retinoic acid inducible gene-I (RIG-I) is a cytoplasmic RNA sensor for detecting a variety of RNA viruses including influenza A viruses. Detection ultimately produces Type I interferon (IFN), which stimulates expression of interferon stimulated genes (ISGs), including RIG-I itself in a positive feedback loop. The structure and function of RIG-I is conserved across phylogeny, despite significant protein sequence divergence, however, the promoter sequences do not show the expected phylogenetic relationships and it is not known whether they are similarly regulated. We previously cloned duck RIG-I and showed it is highly induced during influenza A infection consistent with induction by the interferon produced. Here, we identified the Pekin duck RIG-I promoter and constructed promoter reporter vectors, which we transfected into duck embryonic fibroblasts or chicken DF-1 cells and tested in dual luciferase assays. We showed that activation of the Mitochondrial Antiviral Signalling (MAVS) pathway using the constitutively active N-terminal region of RIG-I or polyinosinic-polycytidylic acid (poly I:C) led to stimulation of duck RIG-I promoter activity. Using deletion constructs we showed the core promoter lies in the proximal 250 basepairs, and we identified essential cis-regulatory elements, a GC-box and an interferon-sensitive response element (ISRE), responsible for basal and inducible expression, respectively. Using mCherry-tagged interferon regulatory factors (IRFs) cloned from chickens and ducks, we show overexpression of chIRF7 induced the duck RIG-I promoter, and this required the ISRE site. Finally, we also demonstrated that overexpressed chIRF7 translocated to the nucleus, which was augmented by MAVS activation using RIG-I 2CARD. Our findings demonstrate that RIG I expression is induced by chIRF7, in a positive regulatory loop. These studies show that the duck RIG-I promoter is appropriately regulated in chicken cells, necessary for the potential generation of transgenic chickens expressing RIG-I. PMID- 30286409 TI - Sulthiame add-on therapy in children with Lennox-Gastaut syndrome: A study of 44 patients. AB - PURPOSE: The aim of this study was to evaluate efficacy and tolerability of sulthiame as an add-on treatment in 44 patients with Lennox-Gastaut syndrome (LGS) refractory to other antiepileptic drugs and/or non-pharmacological treatment. METHODS: Patients were selected according to the following criteria: (1) age 4 years or older, (2) a diagnosis of LGS refractory to at least four previous antiepileptic drugs, alone or in combination. Neurologic examinations, brain magnetic resonance imaging, and repeated prolonged electroencephalography (EEG) or video-EEG studies were performed in all cases. Data on school achievements and/or neuropsychological evaluations were obtained during the follow-up of 1-3 years. Sulthiame was added in doses ranging from 5 to 30 mg/kg/day. RESULTS: Twenty-seven of 44 patients (61%) who received sulthiame as add-on therapy had a greater than 50% seizure decrease after a mean follow-up period of 20 months. Complete seizure freedom was achieved in one patient (2%). Four patients (9%) had a 25-50% seizure decrease, while seizure frequency remained unchanged in 12 (25%), and was increased in one (2%). Hyperpnoea and dyspnoea were observed in four patients, and nausea, drowsiness, and headache were seen in one patient each; however, these manifestations were transient and discontinuation of sulthiame was not necessary. Two other patients had decreased appetite, skin rash, and irritability. The adverse effects were mild and transient in these nine cases. CONCLUSION: Sulthiame as an adjunctive therapy achieved a more than 50% seizure reduction in 27 of 44 patients with LGS with only mild or moderate adverse effects. PMID- 30286410 TI - Narrative analysis of written accounts about living with epileptic or psychogenic nonepileptic seizures. AB - PURPOSE: This study is based on a narrative analysis of individuals' written accounts of living with epilepsy (n = 29) or psychogenic non-epileptic seizures (n = 20, PNES). Narrative analysis looks at both the content and structure of the personal account. We used a form of narrative analysis that allowed us to identify common story lines, otherwise known as narrative typologies, potentially characteristic of these patient groups. Different narrative typologies were described and compared between writers with the two conditions. METHODS: As part of a therapeutic writing intervention for individuals living with a seizure disorder, participants were asked to write for at least 20 min about their very deepest thoughts and feelings about their condition. RESULTS: Five narrative typologies emerged: 1. 'Losses from Illness' - stories were dominated by events individuals could no longer do, authors appeared more disabled reporting greater frequency of seizures and lower health-related quality of life. 2.'Feeling Lost' participants appeared to be in search of something and expressed uncertainty. 3.'Tackling Adversity' - individuals strove to not let their condition stop them from living their life. 4.'Overcoming Challenges' - stories reflected that the condition must be battled and fought with. 5.'A Normal Life' - individuals had demonstrated that they are managing to live with their condition. CONCLUSIONS: While the 'Tackling Adversity' typology was preferentially used by writers with epilepsy, the 'Feeling Lost' typology was chosen more commonly by those with PNES. People with epilepsy narrate their disorder differently from those with PNES, suggesting that they have different life and illness experiences. PMID- 30286411 TI - Analysis of microvascular blood flow and oxygenation: Discrimination between two haemodynamic steady states using nonlinear measures and multiscale analysis. AB - OBJECTIVE: This study investigates the feasibility of the use of nonlinear complexity methods as a tool to identify altered microvascular function often associated with pathological conditions. We evaluate the efficacy of multiscale nonlinear complexity methods to account for the multiple time-scales of processes modulating microvascular network perfusion. METHODS: Microvascular blood flux (BF) and oxygenation (OXY: oxyHb, deoxyHb, totalHb and SO2%) signals were recorded simultaneously at the same site, from the skin of 15 healthy young male volunteers using combined laser Doppler fluximetry (LDF) and white light spectroscopy. Skin temperature was clamped at 33 degrees C prior to warming to 43 degrees C to generate a local thermal hyperaemia (LTH). Conventional and multiscale variants of sample entropy (SampEn) were used to quantify signal regularity and Lempel and Ziv (LZ) and effort to compress (ETC) to determine complexity. RESULTS: SampEn showed a decrease in entropy during LTH in BF (p = 0.007) and oxygenated haemoglobin (oxyHb) (p = 0.029). Complexity analysis using LZ and ETC also showed a significant reduction in complexity of BF (LZ, p = 0.003; ETC, p = 0.002) and oxyHb (p < 0.001, for both) with LTH. Multiscale complexity methods were better able to discriminate between haemodynamic states (p < 0.001) than conventional ones over multiple time-scales. CONCLUSION: Our findings show that there is a good discrimination in complexity of both BF and oxyHb signals between two haemodynamic steady states which is consistent across multiple scales. SIGNIFICANCE: Complexity-based and multiscale-based analysis of BF and OXY signals can identify different microvascular functional states and thus has potential for clinical application in the prognosis and the diagnosis of pathophysiological conditions such as microvascular dysfunction observed in non alcoholic fatty liver disease and type 2 diabetes. PMID- 30286412 TI - Visualizing the detection area of a unilateral NMR sensor using deconvolution and back-projection. AB - Understanding the detection volume of a unilateral NMR sensor is crucial to interpret acquired data appropriately. Whereas this is easily done in the sensor's axial dimension by running a depth profile on a well-defined sample, the lateral dimension is commonly characterized with very small samples, where each position along a regular grid is scanned individually, typically resulting in measurement times of several days and a resolution that is limited to the dimensions of the sample. Here we apply two mathematical procedures known from image processing that employ samples larger than the pixel size to characterize the lateral detection area. One procedure uses deconvolution algorithms to account for blurring effects caused by a larger sample while the other utilizes back-projection of radial field profiles. Both approaches are demonstrated with a Profile NMR-MOUSE(r) (PM5). They yield field maps in good agreement with those acquired with pixel-size test samples but save about one order of magnitude in scanning time. PMID- 30286413 TI - Real-time J-upscaling in two-dimensional pure shift diagonal NMR: Simultaneous resolution enhancement in chemical shifts and scalar couplings. AB - A two-dimensional real-time J-upscaled pure shift diagonal pulse scheme, JS PSYCHE-DIAG has been developed. This method enhances the resolution in scalar coupling multiplets by real-time J-upscaling during the direct acquisition, and these J-upscaled multiplets resolve on the diagonal at the respective pure shift positions, which results in resolution enhancement in chemical shifts. Thus, both chemical shifts and scalar couplings get better resolved simultaneously in the same NMR experiment. The efficacy of the present method has been demonstrated, (i) on hesperidin for resolving the J-upscaled multiplets belonging to diastereomers and (ii) on a natural product, strychnine, to measure small scalar couplings including the long range values. PMID- 30286414 TI - Temperament traits and remission of depression: A naturalistic six-month longitudinal study. AB - BACKGROUND: The aim of this naturalistic longitudinal study was to add evidence regarding the potential of Cloninger's temperament traits (novelty seeking, harm avoidance, reward dependence and persistence) for predicting the effect of pharmacological treatment on the rates of therapeutic response and remission. METHODS: The study was based on 200 outpatients with unipolar depressive disorders of different severity and course of illness, and extended up to 6 months of follow-up. Patients were assessed in their temperament with the Tridimensional Personality Questionnaire (TPQ) and their condition was classified (in course and severity) according to the International Classification of Diseases, Tenth revision (ICD-10) diagnostic criteria for research. Patients were blindly rated (concerning other predicting variables) on the improved Clinical Global Impression-Severity scale for depression (iCGI-S) at baseline, 6 weeks, 3 months and 6 months. Outcome measures at the last observation carried forward were therapeutic response (reduction of >=50% in the last iCGI-S) and remission (last iCGI-S = 0), which were available for 187 patients. RESULTS: Remission was independently and directly associated with length of follow-up, and inversely with the baseline iCGI-S score and harm avoidance (patients in the high tertile had a 2.7 likelihood of non-remission in comparison with those in the low tertile); persistence was found to have a complex, V-shape relationship with remission. Within a sub-sample of more severe cases (n = 118), having higher harm avoidance scores, a more favorable outcome was associated with higher reward dependence and the non-smoking condition. LIMITATIONS: With a naturalistic, non experimental design, the sample may not be representative of the general population. CONCLUSIONS: Temperament traits may help predict outcome in patients treated for depression. PMID- 30286415 TI - A systematic meta-review of predictors of antidepressant treatment outcome in major depressive disorder. AB - INTRODUCTION: The heterogeneity of symptoms and complex etiology of depression pose a significant challenge to the personalization of treatment. Meanwhile, the current application of generic treatment approaches to patients with vastly differing biological and clinical profiles is far from optimal. Here, we conduct a meta-review to identify predictors of response to antidepressant therapy in order to select robust input features for machine learning models of treatment response. These machine learning models will allow us to learn associations between patient features and treatment response which have predictive value at the individual patient level; this learning can be optimized by selecting high quality input features for the model. While current research is difficult to directly apply to the clinic, machine learning models built using knowledge gleaned from current research may become useful clinical tools. METHODS: The EMBASE and MEDLINE/PubMed online databases were searched from January 1996 to August 2017, using a combination of MeSH terms and keywords to identify relevant literature reviews. We identified a total of 1909 articles, wherein 199 articles met our inclusion criteria. RESULTS: An array of genetic, immune, endocrine, neuroimaging, sociodemographic, and symptom-based predictors of treatment response were extracted, varying widely in clinical utility. LIMITATIONS: Due to heterogeneous sample sizes, effect sizes, publication biases, and methodological disparities across reviews, we could not accurately assess the strength and directionality of every predictor. CONCLUSION: Notwithstanding our cautious interpretation of the results, we have identified a multitude of predictors that can be used to formulate a priori hypotheses regarding the input features for a computational model. We highlight the importance of large-scale research initiatives and clinically accessible biomarkers, as well as the need for replication studies of current findings. In addition, we provide recommendations for future improvement and standardization of research efforts in this field.

AB - BACKGROUND: Several studies indicate that ketamine has rapid antidepressant effects in patients with treatment-resistant depression (TRD). The extent to which repeated doses of ketamine (versus placebo) reduce depression in the short and long term among outpatients with TRD and chronic, current suicidal ideation remains unknown. METHODS: Twenty-six medicated outpatients with severe major depressive disorder with current, chronic suicidal ideation were randomized in a double-blind fashion to six ketamine infusions (0.5 mg/kg over 45 minutes) or saline placebo over three weeks. Depression and suicidal ideation were assessed at baseline, 240 min post-infusion, and during a three-month follow-up phase. RESULTS: During the infusion phase, there was no differences in depression severity or suicidal ideation between placebo and ketamine (p = 0.47 and p = 0.32, respectively). At the end of the infusion phase, two patients in the ketamine group and one in the placebo group met criteria for remission of depression. At three-month follow-up, two patients in each group met criteria for remission from depression. LIMITATIONS: Limitations include the small sample size, uncontrolled outpatient medication regimens, and restriction to outpatients, which may have resulted in lower levels of suicidal ideation than would be seen in emergency or inpatient settings. CONCLUSIONS: Repeated, non escalating doses of ketamine did not outperform placebo in this double-blind, placebo controlled study of patients with severe TRD and current, chronic suicidal ideation. This result may support our previously published open-label data that, in this severely and chronically ill outpatient population, the commonly used dose of 0.5 mg/kg is not sufficient. PMID- 30286419 TI - The effects of sport specific training of rugby players on avoidance behaviours during a head-on collision course with an approaching person. AB - Individuals use visual information to plan and adapt movements to dynamically changing environments. This information is used to accurately determine when and where they may come in contact with an object. More specifically, individuals may determine the time prior to contacting an object, known as time-to-contact (TTC). Sport provides a scenario where athletes compete in dynamically changing environments and must interact with opposing players. The effects of sport specific training on obstacle avoidance is highly controversial and research suggests the quantifiable differences in behaviours compared to non-athletes is highly context specific. The current study aimed to examine if sport-specific training has an impact on the avoidance behaviours of rugby players during a head on collision course with an approaching person. Female rugby players (N = 10, x- = 20 +/- 0.94 years) and non-athletes (N = 10, x- = 21.9 +/- 1.6 years) were instructed to walk along a 10 m path towards a goal located along the midline. A female confederate initially positioned along the midline 180 degrees from the participant walked towards the participant to one of four predetermined final positions: 1) along the midline in the participants' starting position; 2) stopped along the midline 2.5 m from her starting position; 3) to the left of the participants' starting position; and 4) to the right of the participants' starting position. Results revealed when the path of the confederate was uncertain, individuals used a consistent TTC to determine when to change their path. The rugby players in the current study were found to avoid significantly later (i.e. smaller TTC) than non-athletes. However, following a change in path, sport-specific training did not impact the avoidance behaviours of the groups, but rather the environment was the regulating factor. When the path of the confederate was uncertain, individuals did not use a single avoidance strategy, instead considered the fit between their individual characteristics (i.e., action capabilities) and components of the environment (i.e. path of the confederate and task constraints). Athletes who are specifically trained to pass through spaces and avoid obstacles (i.e., rugby backs) may consider their action capabilities in conjunction with their visual information to determine time of avoidance. PMID- 30286417 TI - The PanCareSurFup consortium: research and guidelines to improve lives for survivors of childhood cancer. AB - BACKGROUND: Second malignant neoplasms and cardiotoxicity are among the most serious and frequent adverse health outcomes experienced by childhood and adolescent cancer survivors (CCSs) and contribute significantly to their increased risk of premature mortality. Owing to differences in health-care systems, language and culture across the continent, Europe has had limited success in establishing multi-country collaborations needed to assemble the numbers of survivors required to clarify the health issues arising after successful cancer treatment. PanCareSurFup (PCSF) is the first pan-European project to evaluate some of the serious long-term health risks faced by survivors. This article sets out the overall rationale, methods and preliminary results of PCSF. METHODS: The PCSF consortium pooled data from 13 cancer registries and hospitals in 12 European countries to evaluate subsequent primary malignancies, cardiac disease and late mortality in survivors diagnosed between ages 0 and 20 years. In addition, PCSF integrated radiation dosimetry to sites of second malignancies and to the heart, developed evidence-based guidelines for long-term care and for transition services, and disseminated results to survivors and the public. RESULTS: We identified 115,596 individuals diagnosed with cancer, of whom 83,333 were 5-year survivors and diagnosed from 1940 to 2011. This single data set forms the basis for cohort analyses of subsequent malignancies, cardiac disease and late mortality and case-control studies of subsequent malignancies and cardiac disease in 5-year survivors. CONCLUSIONS: PCSF delivered specific estimates of risk and comprehensive guidelines to help survivors and care-givers. The expected benefit is to provide every European CCS with improved access to care and better long-term health. PMID- 30286420 TI - Continuous column adsorption of naphthenic acids from synthetic and real oil sands process-affected water (OSPW) using carbon-based adsorbents. AB - In this study, activated petroleum coke (APC) and commercial activated carbon (CAC) were used in a continuous adsorption column for removal of model naphthenic acids and organics from real oil sands process-affected water (OSPW). Diphenylacetic acid and 2-naphthoic acid, two model naphthenic acid (NA) compounds, were removed completely by the APC in a continuous column operation. Due to the complex nature of organics in OSPW, total organic carbon (TOC) was measured to determine the effectiveness of OSPW treatment by APC. The removal of TOC from OSPW at its natural pH 8 by APC was only 25%, whereas acidification at pH 4 followed by APC adsorption removed 96% of the initial TOC. When compared to a commercial activated carbon, the APC showed an average of 20% higher organics removal. The experimental breakthrough curves were better fitted by Thomas model in comparison to Adams-Bohart and Yoon-Nelson models. The regeneration of APC was conducted using methanol with 0.01 wt% NaOH (pH = 11.7) and a total of four cycles of adsorption and regeneration were conducted with marginal loss of adsorption sites. PMID- 30286418 TI - Results of a multicentre randomised controlled trial of cochlear-sparing intensity-modulated radiotherapy versus conventional radiotherapy in patients with parotid cancer (COSTAR; CRUK/08/004). AB - PURPOSE: About 40-60% of patients treated with post-operative radiotherapy for parotid cancer experience ipsilateral sensorineural hearing loss. Intensity modulated radiotherapy (IMRT) can reduce radiation dose to the cochlea. COSTAR, a phase III trial, investigated the role of cochlear-sparing IMRT (CS-IMRT) in reducing hearing loss. METHODS: Patients (pT1-4 N0-3 M0) were randomly assigned (1:1) to 3-dimensional conformal radiotherapy (3DCRT) or CS-IMRT by minimisation, balancing for centre and radiation dose of 60Gy or 65Gy in 30 daily fractions. The primary end-point was proportion of patients with sensorineural hearing loss in the ipsilateral cochlea of >=10 dB bone conduction at 4000 Hz 12 months after radiotherapy compared using Fisher's exact test. Secondary end-points included hearing loss at 6 and 24 months, balance assessment, acute and late toxicity, patient-reported quality of life, time to recurrence and survival. RESULTS: From Aug 2008 to Feb 2013, 110 patients (54 3DCRT; 56 CS-IMRT) were enrolled from 22 UK centres. Median doses to the ipsilateral cochlea were 3DCRT: 56.2Gy and CS IMRT: 35.7Gy (p < 0.0001). 67/110 (61%) patients were evaluable for the primary end-point; main reasons for non-evaluability were non-attendance at follow-up or incomplete audiology assessment. At 12 months, 14/36 (39%) 3DCRT and 11/31 (36%) CS-IMRT patients had >=10 dB loss (p = 0.81). No statistically significant differences were observed in hearing loss at 6 or 24 months or in other secondary end-points including patient-reported hearing outcomes. CONCLUSION: CS-IMRT reduced the radiation dose below the accepted tolerance of the cochlea, but this did not lead to a reduction in the proportion of patients with clinically relevant hearing loss. PMID- 30286421 TI - Photodegradation of fluazaindolizine in water under simulated sunlight irradiation: Identification of transformation products and elucidation of transformation mechanism. AB - The photodegradation of fluazaindolizine in water was investigated under simulated sunlight irradiation. The effects of solution pH, humic acids (HA), nitrates (NO3-) and Fe(III) ions on photolysis of fluazaindolizine were studied. The results indicated that pH did not significantly affect its photodegradation. At low concentration (up to 5 mg/L), HA slightly facilitated the photodegradation of fluazaindolizine, while at high concentration (10-20 mg/L), HA inhibited its photodegradation. The presence of NO3- (0-10 mg/L) and Fe(III) (0-5 mg/L) noticeably accelerated the photodegradation of fluazaindolizine. Moreover, eleven direct transformation products (TPs) were isolated and identified by liquid chromatography quadrupole time-of-flight mass spectrometry. Density functional theory (DFT) calculation was utilized to characterize molecular property of fluazaindolizine and predict the potentiality of the possible photodegradation reaction. Ultimately, a possible transformation mechanism was proposed based on the identified TPs, degradation profiles and DFT calculation. The predominant photoproduct came from ring opening of imidazole-ring and dechlorination. Other TPs resulted from a series of photochemical reactions involving hydroxyl substitution, ring-opening, cleavage, oxidation and decarboxylation. These results were important in elucidating environmental fate of fluazaindolizine in aquatic system and further environmental risk assessment. PMID- 30286422 TI - Promotional effect of doping Cu into cerium-titanium binary oxides catalyst for deep oxidation of gaseous dichloromethane. AB - In recent years, significant effort has been made in the development of novel catalysts for the total oxidation of chlorinated volatile organic compounds. In this work the catalytic activity of Cu doped cerium-titanium binary oxides for the oxidation of dichloromethane (DCM) have been studied for the first time. Combining catalysts characterization and activity data, it was found that Cu ions can uniformly disperse into titanium dioxide to form solid solution and induce the creation of additional surface oxygen species on the catalysts surface, while moderate amount of Ce ions are still needed for the activation of CCl. Detailed analysis of the in-situ FTIR experiment results revealed that the surface oxygen species, especially the hydroxyl groups associated with Cu ions, can promote the deep oxidation of the intermediate species formed in the nucleophilic substitution process occurred on the active sites of catalysts surface. The sample with the Cu/Ce molar ratio of 1:3 obtained a better CO2 selectivity than that reached with cerium-titanium binary oxides. Meanwhile, according to element balance analysis, removal of chlorine from the catalyst surface was also promoted by Cu doping. PMID- 30286423 TI - Synergism and antagonisms between nutrients induced by copper toxicity in grapevine rootstocks: Monocropping vs. intercropping. AB - The long-term use of Cu-containing fungicides contaminates vineyards soils, which can induce Cu toxicity and nutrient imbalances in several plant species. The aim of this work was to evaluate the effect of Cu toxicity on two grapevine rootstocks, Fercal and 196.17, and to elucidate if intercropping with oat can alleviate grapevine Cu toxicity. Plants were hydroponically-cultivated and treated with different Cu concentrations. At harvest the biomass accumulation, the SPAD index and the symplastic and apoplastic root and leaves ionome were measured to evaluate possible synergistic and/or antagonistic effects on other micro- and macronutrients. The root exudation analysis was correlated with genes expression (VvPEZ-like), whereas PCA analysis performed on the grapevine and oat ionome revealed that both mono- and intercropped 196.17 rootstock display a positive effect on Zn and Mn in the root tissues at high Cu concentrations. An increase of Zn and Mn in roots was also reported for the intercropped Fercal rootstock at high Cu concentrations while an antagonistic relation was reported for root Zn concentration in the monocropped Fercal rootstock. Our results showed that grapevine and oat compete for nutrient uptake and that this phenomenon can possibly alleviate grapevine Cu toxicity. However, Fercal rootstock is able to take advantage from oat, while 196.17 is disadvantaged by the intercropping system. Even though intercropping system seems to be a valuable tool to counteract grapevine Cu toxicity, the application of this agricultural practice has shown to be species dependent and should be evaluated for each rootstock. PMID- 30286424 TI - Effects of different concentrations of Microcystis aeruginosa on the intestinal microbiota and immunity of zebrafish (Danio rerio). AB - Microcystis aeruginosa is a primary species of toxin-producing cyanobacteria. This study explored the effects of short-term exposure (96 h) to M. aeruginosa on the intestinal microflora variation and immune function of zebrafish. After exposure to different cell concentrations of M. aeruginosa, marked histological variation was observed in the intestine, such as goblet cells proliferation and intestinal desquamation. In addition high-concentration M. aeruginosa treatment (initial concentration: 1.59 * 105 cells mL-1) induced a significant increase in cytokine levels compared with other groups. Low-concentration M. aeruginosa treatment (initial concentration: 0.88 * 105 cells mL-1) promoted the transcription of inflammatory genes, while high-concentration treatment restrained the transcription of these genes. Moreover, M. aeruginosa exposure also changed the intestinal microbial diversity. At the phylum level, bacteria belonging to Proteobacteria were the most abundant in all groups, and Gammaproteobacteria were the dominant bacteria with major changes. Pathogenic microorganisms such as Shewanella, Plesiomonas, Halomonas, Pseudomonas, and Lactobacillus increased greatly after treatment with different cell concentrations of M. aeruginosa. This study indicates that M. aeruginosa induces an increase in zebrafish goblet cells and enhances the inflammatory response, which may produce detrimental effects in zebrafish, resulting in a greater proportion of pathogenic bacteria and intestinal injury. The results of this study will help improve the understanding of the effects of M. aeruginosa on the intestines of aquatic organisms. PMID- 30286426 TI - Indoor air pollution and exposure assessment of the gulf cooperation council countries: A critical review. AB - Indoor air pollution is one of the human health threat problems in the Gulf Cooperation Council (GCC) countries. In these countries, due to unfavorable meteorological conditions, such as elevated ambient temperature, high relative humidity, and natural events such as dust storms, people spend a substantial amount of their time in indoor environments. In addition, production of physical and biological aerosols from air conditioners, cooking activities, burning of Arabian incense, and overcrowding due to pilgrimage programs are common causes of low quality indoor air in this region. Thus, due to infiltration of outdoor sources as well as various indoor sources, people living in the GCC countries are highly exposed to indoor air pollutants. Inhalation of indoor air pollutants causes mortalities and morbidities attributed to cardiorespiratory, pulmonary, and lung cancer diseases. Hence, the aim of this review study is to provide a summary of the major findings of indoor air pollution studies in different microenvironments in six GCC countries. These include characterization of detected indoor air pollutants, exposure concentration levels, source identifications, sustainable building designs and ventilation systems, and the mitigation strategies. To do so, >130 relevant indoor air pollution studies across the GCC countries were critically reviewed. Particulate matters (PM10 and PM2.5), total volatile organic compounds (TVOCs), carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen dioxide (NO2), and heavy metals were identified as the reported indoor air pollutants. Apart from them, indoor Radon and bioaerosols were studied only in specific GCC countries. Thus, future studies should also focus on the investigation of emerging indoor air pollutants, such as ultrafine and nanoparticles and their associated health effects. Furthermore, studies on the mitigation of indoor air pollution through the development of advanced air purification and ventilation systems could improve the indoor air quality (IAQ) in the GCC region. PMID- 30286425 TI - Monitoring WWTP performance using size-exclusion chromatography with simultaneous UV and fluorescence detection to track recalcitrant wastewater fractions. AB - A trial monitoring of a typical full-scale municipal WWTP in Central Finland was aimed to explore applicability of high performance liquid chromatography - size exclusion chromatography (HPSEC) with simultaneous UV and fluorescence detection as a tool for advanced routine monitoring of wastewater treatment. High, intermediate, and low molecular weight (MW) fractions of untreated wastewater (influent) and treated wastewater (secondary effluent) were characterized in terms of UV absorbance at 254 nm (UVA254) and specific fluorescence representing tyrosine-like, tryptophan-like, and humic/fulvic-like compounds. The activated sludge treatment removed 97 +/- 1% of BOD, 93 +/- 2% of COD, 71 +/- 7% of DOC, and 24 +/- 7% of TN, while the overall reduction of UVA254 was 50 +/- 6%. Total fluorescence signal declined by ~80% for tyrosine-like, by 60-70% for tryptophan like, and by 7-36% for humic/fulvic-like compounds. Low and intermediate MW humic/fulvic-like compounds fluorescing at lambdaex/lambdaem = 390/500 nm demonstrated recalcitrant behavior. Protein-like and humic/fulvic-like fractions of low MW < 1 kDa accounted for 60-65% of total UVA254 and 50-70% of total fluorescence of whole influent and effluent samples. Strong linear correlations were observed between wastewater BOD, COD, DOC, UVA254 and tyrosine-like, tryptophan-like fluorescence. PMID- 30286427 TI - Insertion position as well as the inserted TRS and gene sequences differentially affect the retention of foreign gene expression by simian hemorrhagic fever virus (SHFV). AB - Recombinant SHFV infectious cDNA clones expressing a foreign gene from an additional sg mRNA were constructed. Two 3' genomic region sites, between ORF4' and ORF2b and between ORF4 and ORF5, were utilized for insertion of the myxoma M013 gene with a C-terminal V5 tag followed by one of the three inserted transcription regulatory sequences (TRS), TRS2', TRS4' or TRS7. M013 insertion at the ORF4'/ORF2b site but not the ORF4/ORF5 site generated progeny virus but only the recombinant virus with an inserted TRS2' retained the entire M013 gene through passage four. Insertion of an auto-fluorescent protein gene, iLOV, with an inserted TRS2' at the ORF4'/ORF2b site, generated viable progeny virus. iLOV expression was maintained through passage eight. Although regulation of SHFV subgenomic RNA synthesis is complex, the ORF4'/ORF2b site, which is located between the two sets of minor structural proteins, is able to tolerate foreign gene insertion. PMID- 30286428 TI - Magnitude processing of written number words is influenced by task, rather than notation. AB - The extent to which task and notation influence the processing of numerical magnitude is under theoretical and empirical debate. To date, behavioural studies have yielded a mixed body of evidence. Using the case of written number words in English and Chinese, we re-examined this issue. Thirty-nine bilingual participants who showed a balanced profile of language dominance in English and Chinese completed three tasks of numerical processing (Magnitude Comparison, Numerical Matching, and Language Matching) with pure English, pure Chinese, and mixed notation number words. We conducted frequentist and Bayesian statistics on the data. Magnitude processing, as indexed by the numerical distance effect (NDE), was found to be dependent on task. Specifically, the NDE occurred in all notation conditions in the Magnitude Comparison Task and mixed notation trials in the Numerical Matching Task only. However, the data indicated that magnitude processing was independent of notation. Task and notation had an interactive influence on overall speed of processing, where participants responded to Chinese number words significantly faster than other notations for the Magnitude Comparison and Numerical Matching Tasks only. Finally, Bayesian analyses indicated that task and notation do not interact to affect magnitude processing. Specifically, the Bayes Factor and posterior model probabilities of the Bayesian ANOVA yielded strongest support for the model with three main effects (Task, Notation, Numerical Distance) and two two-way interactions (Task * Numerical Distance, Task * Notation). These findings highlight the critical role of task in numerical magnitude processing, provide support for a notation-independent account of magnitude processing, and suggest that linguistic/orthographic factors, combined with task, may interact to affect overall speed of processing. PMID- 30286429 TI - Differential inter-trial effects in the visual search of children, adolescents, and young adults. AB - We examined the age-related variation in one type of inter-trial effect of visual search, the distractor previewing effect (DPE), in affectively neutral and affectively charged contexts. In Experiment 1, children, adolescents, and young adults were faster to identify the shape of a color target when the color of the current distractors had already been previewed than when the target had been previewed in the preceding target-absent trial, indicative of a color-based DPE. The results revealed a greater DPE in children than in adolescents and young adults, but it can be attributed to children's slower RTs than the other two groups. In Experiment 2, children, adolescents, and young adults were instructed to respond to a schematic face that was different from the other two faces. Young adults were faster in searching for a threatening face among friendly ones when they had previewed a target-absent display consisting of friendly faces than that of threatening faces, indicating an emotional DPE. By contrast, children showed a reversed DPE under the same condition, whereas adolescents showed no DPE. Taken together, these results suggested that the three age groups were all able to create an inhibitory attentional bias on the basis of trial history in affectively neutral context, whereas children and adolescents were not able to create such an inhibitory attentional bias in affectively charged contexts in the same way as adults did. These findings implied that the development of attentional inhibition abilities in affectively charged contexts might be delayed compared to those in affectively neutral contexts. PMID- 30286430 TI - EGR1 is essential for deoxynivalenol-induced G2/M cell cycle arrest in HepG2 cells via the ATF3DeltaZip2a/2b-EGR1-p21 pathway. AB - Deoxynivalenol (DON) is a type B trichothecene mycotoxin that exerts multiple toxic effects on plants, animals and humans. Several reports have shown that DON leads to G2/M cell cycle arrest. However, its molecular mechanism is still unclear. In this study, we showed that DON induced strong G2/M cell cycle arrest in HepG2 cells, and the cell cycle-inhibitory protein p21 was highly upregulated by DON. Further analysis showed that the cell cycle regulating gene EGR1 was highly induced by DON and that EGR1 knockdown abolished the upregulation of p21 and G2/M cell cycle arrest. Furthermore, we showed that the induction of EGR1 was regulated by the stress-responsive transcription factor ATF3. ATF3DeltaZip2a/2b, which is a DNA binding domain truncated isoform of ATF3, was upregulated by DON. ATF3 knockdown weakened the expression induction of EGR1 and G2/M cell cycle arrest by DON. Moreover, the upregulation of ATF3DeltaZip2a/2 highly depended on the enhanced presence of histones H3K9ac and H3K27ac. H3K9ac and H3K27ac were enriched at the promoter region of ATF3 following the DON treatment, and the knocking down of the genes responsible for H3K9ac and H3K27ac abolished the upregulation of ATF3 by DON. In summary, we found that DON induced G2/M cell cycle arrest by sequentially inducing the expression of ATF3DeltaZip2a/2b, EGR1 and p21, and EGR1 played an essential role in this process, which is a novel molecular mechanism of cell cycle arrest by DON and is important for understanding its toxicology. PMID- 30286431 TI - Fluorinated CdSe/ZnS quantum dots: Interactions with cell membrane. AB - Fluorescent inorganic quantum dots are highly promising for biomedical applications as sensing and imaging agents. However, the low internalization of the quantum dots, as well as for most of the nanoparticles, by living cells is a critical issue which should be solved for success in translational research. In order to increase the internalization rate of inorganic CdSe/ZnS quantum dots, they were functionalized with a fluorinated organic ligand. The fluorinated quantum dots displayed an enhanced surface activity, leading to a significant cell uptake as demonstrated by in vitro experiments with HeLa cells. We combined the experimental and computational results of Langmuir monolayers of the DPPC phospholipid as a model cell membrane with in vitro experiments for analyzing the mechanism of internalization of the fluorinated CdSe/ZnS quantum dots. Surface pressure-molecular area isotherms suggested that the physical state of the DPPC molecules was greatly affected by the quantum dots. UV-vis reflection spectroscopy and Brewster Angle Microscopy as in situ experimental techniques further confirmed the significant surface concentration of quantum dots. The disruption of the ordering of the DPPC molecules was assessed. Computer simulations offered detailed insights in the interaction between the quantum dots and the phospholipid, pointing to a significant modification of the physical state of the hydrophobic region of the phospholipid molecules. This phenomenon appeared as the most relevant step in the internalization mechanism of the fluorinated quantum dots by cells. Thus, this work sheds light on the role of fluorine on the surface of inorganic nanoparticles for enhancing their cellular uptake. PMID- 30286432 TI - LncRNAs on guard. AB - Long noncoding RNAs (lncRNAs) are emerging as crucial regulators of gene expression in immune system. It has been reported that lncRNAs participate in regulation of immune responses through both transcriptional and post transcriptional mechanisms. In this review, we summarize the molecular functions of lncRNAs and discuss their binding to DNA, RNA and protein targets. We focus on the regulatory function of lncRNAs in both innate and adaptive immunity, as well as in autoimmunity and cancer immunology. In addition, we point out the limitation in current knowledge and future directions for the study of lncRNAs in the immune system. PMID- 30286433 TI - Association between residential self-selection and non-residential built environment exposures. AB - Studies employing 'activity space' measures of the built environment do not always account for how individuals self-select into different residential and non residential environments when testing associations with physical activity. To date, no study has examined whether preferences for walkable residential neighborhoods predict exposure to other walkable neighborhoods in non-residential activity spaces. Using a sample of 9783 university students from Toronto, Canada, we assessed how self-reported preferences for a walkable neighborhood predicted their exposure to other walkable, non-residential environments, and further whether these preferences confounded observed walkability-physical activity associations. We found that residential walkability preferences and non residential walkability were significant associated (beta = 0.42, 95% CI: (0.37, 0.47)), and further that these preferences confounded associations between non residential walkability exposure and time spent walking (reduction in association = 10.5%). These results suggest that self-selection factors affect studies of non residential built environment exposures. PMID- 30286434 TI - Geographic variation in the impact of a type 2 diabetes diagnosis on behavioural change: A longitudinal study using random effects within-between (REWB) models. AB - A type 2 diabetes (T2DM) diagnosis has been referred to as a "wake-up call", but subsequent behavioural change may be influenced by place of residence. Random effects within-between regressions were applied to 130,926 participants in the 45 and Up Study. T2DM diagnoses effected change in the odds of short sleeps and meeting vegetable and alcohol consumption guidelines, but not changes in physical activity. Each of these behaviours varied geographically and were patterned by area disadvantage and geographic remoteness. Impacts of T2DM diagnosis on behavioural change were not found to be geographically contingent, though analysis of specific environmental attributes is warranted. PMID- 30286435 TI - New insights into phenol and polyphenol composition of Stevia rebaudiana leaves. AB - The diversity in phenols and polyphenols of stevia leaf has been simplified applying sequential fractionation techniques on its ethanol extract through ultrasound assisted maceration. Two of the fractions obtained by reverse-phase column chromatography resulted differently active in an extensive antioxidant and cytotoxic screening. Both fractions were chemically profiled by ultra-performance liquid chromatography (UHPLC) coupled with electrospray ionization (ESI) quadrupole/time-of-flight (QqTOF) mass spectrometry (MS). One of the fractions was composed mainly of chlorogenic acids and flavonol triglycosides, whereas the other was rich in flavonoids mono- and diglycosides and in their hydroxycinnamoyl derivatives. Among the fifty compounds identified, non-phenol metabolites, such as benzyl primeveroside and roseoside, as well as a lignan polyphenol (5'), are reported for the first time as constituents of the Stevia leaf. PMID- 30286436 TI - Determination of inorganic anions in the whole blood by ion chromatography. AB - A fast, precise, and accurate method that can simultaneously determine 7 anions in whole blood was established by on line dialysis-double suppression ion chromatography. Performance parameters which could affect the determination of anions were optimized, including the selection of protein precipitant in samples, the amount of filtrate discarded, selection of eluent flow rate, influence of the Ag-Na column on experimental results, influence of ethylenediamines on ClO2-, and investigation of nitrogen drying. Finally, 3.6 mmol/L sodium carbonate was selected as eluent, with a flow rate of 0.8 mL/min, to separate the 7 anions. Blood and alcohol (v/v, 1:4) were used to precipitate the proteins in blood. The 7 anions reached an adequate recovery rate when the first 2 mL of filtrate from the C18 column was discarded. The recovery rate at LLOQ, low, medium, and high concentrations was 80-120%. The correlation coefficients (r2) of the calibration curves of the targeted anions ranged from 0.9975 to 0.9998. The limit of detection (LOD) was 0.309-7.71 MUg/L. This method has simple pretreatment, high accuracy, and good reproducibility and selectivity, and is suitable for the separation and determination of anions in blood. PMID- 30286437 TI - 1H NMR-based dynamic metabolomics delineates the therapeutic effects of Baoyuan decoction on isoproterenol-induced cardiac hypertrophy. AB - Cardiac hypertrophy (CH) is a major risk factor for many serious heart diseases. Sustained CH is catastrophic, resulting in cardiac dysfunction that eventually leads to heart failure (HF). Baoyuan decoction (BYD) is a famous traditional Chinese medicine (TCM) formula for supplementing and reinforcing Qi, clinically used for the treatment of cardiovascular diseases (CVDs). However, the therapeutic effects of BYD on CH remain unidentified. We herein investigated the effect of BYD on isoproterenol (ISO)-induced CH in rats and the underlying mechanisms by comprehensive pharmacodynamics and 1H NMR-based dynamic metabolomics analysis of the plasma and urine samples. Results showed that BYD treatment markedly attenuated ISO-induced CH as evidenced by decreasing the left ventricular wall thickness, pathological cardiomyocyte hypertrophy, myocardial collagen fiber deposition and apoptosis, and plasma natriuretic peptide levels. Multivariate trajectory analysis revealed that the BYD treatment could restore the CH-disturbed plasma and urinary metabolite profiles towards the normal metabolic status featuring with a time-dependent tendency. Moreover, the key metabolic alterations in CH rats at different BYD-treated time stages involved energy metabolism, oxidative stress responses, amino acid metabolism, and gut microbiota metabolism. Of particularly, the significant roles of BYD for treating CH lie in the improvement of cardiac energy generation and antioxidant capacity. Our investigation provides a holistic view of BYD for therapeutic intervention of CH through monitoring of the dynamic metabolic changes and the results indicate that BYD may be applied as a potential agent for treating CH.

AB - Bombyx batryticatus, the dried larva of Bombyx mori L. (4th-5th instars) infected with Beauveria bassiana Vuill, is an important animal-derived medicine effective against several diseases. The metamorphosis of silkworm can result insignificant changes in the levels of proteins and polypeptides in the 4th and 5th instar larvae. Here, we performed extensive characterization of Bombyx batryticatus peptides, including polypeptides containing cysteines, using an MS-based data mining strategy. A total of 779 peptides with various PTMs (post-translational modifications) were identified through database search and de novo sequencing. Some of these peptides might have important biological activities. Besides, the differential analysis of polypeptides between the head and body of Bombyx batryticatus was performed to provide a clinical basis for rational use of the drugs derived from it. This study illustrates the abundance and sequences of endogenous Bombyx batryticatus polypeptides, and thus, provides potential candidates for the screening of active compounds for future biological research and drug discovery studies.

AB - Ginkgolic acids (GAs) and Ginkgotoxin (4'-O-methylpyridoxine, MPN) are main toxic compounds in Ginkgo biloba seeds which are widely used in the treatment of coughing in China. To evaluate the pharmacokinetics of GAs, MPN and their metabolites in rat plasma, a highly sensitive method followed by ultra-high pressure liquid chromatography coupled with linear ion trap-Orbitrap tandem mass spectrometry (UHPLC-LTQ-Orbitrap-MS) has been developed and validated. The proposed method is selective, precise and accurate enough of MPN and its metabolites (4-pyridoxic Acid, pyridoxal, and pyridoxine) for the pharmacokinetic study. After oral administration of MPN, the plasma concentrations of MPN and its metabolites were increased rapidly. Meanwhile, an investigation was carried out to compare the interactions of the pharmacokinetic profiles of MPN and GAs. Five GAs and main metabolites of GA (15:1) and GA (17:1) were also analyzed by using our previous method. After coadministration GAs with MPN, Tmax of MPN delayed and Cmax decreased. Meanwhile, Tmax of 4-pyridoxic Acid, pyridoxal, and pyridoxine were also showed a certain degree of delay. The concentrations of hydroxylation products of GA (15:1) and GA (17:1) increased at a slower rate and the area under the curves was significantly reduced. However, glucuronidation metabolites of GA (15:1) and GA (17:1) were increased faster than administered of GAs alone. The interactions of the pharmacokinetic profiles of GAs and MPN in rat plasma after oral administration were obviously observed. PMID- 30286440 TI - Ionic liquid-based salt-induced liquid-liquid extraction of polyphenols and anthraquinones in Polygonum cuspidatum. AB - Ionic liquid-based salt-induced liquid-liquid extraction was developed for the first time and applied to the extraction of four active constituents, including polydatin, resveratrol, emodin, and physcion in Polygonum cuspidatum (P. cuspidatum). In this study, ionic liquid was used as extraction solvent. The dried P. cuspidatum samples purchased from the pharmacy were triturated and passed through a 120-mesh sieve. The obtained sample powders were dried to constant weight at 55 C, and then mixed with extraction solvent. The extraction was carried out with the aid of ultrasound. Three phases, including ionic liquid rich, salt-rich and solid sample phases were formed in the presence of salt. The target analytes were enriched in ionic liquid phase and then determined by high performance liquid chromatography. The experimental parameters, such as type and volume of ionic liquid, type and amount of salt, pH value of extraction medium, ultrasound power, ultrasound time and centrifugal condition, were optimized. The calibration curves showed good linear relationship (r > 0.9994). The limits of detection and quantification were in the range of 2.8-29.5 and 9.4-98.3 ng mL-1, respectively. The spiked recoveries were between 92.16% and 105.41%. Compared with hot reflux extraction and ultrasound-assisted extraction, the proposed method requires less extraction solvent and time. The present method can be applied to the determination of polyphenols and anthraquinones in P. cuspidatum. PMID- 30286441 TI - Targeting the hot spot in a patient with essential tremor and Parkinson's disease: Tractography matters. AB - INTRODUCTION: Thalamic ventralis intermedius deep brain stimulation (VIM-DBS) is generally effective in treating refractory tremor in Parkinson's disease (PD) and in essential tremor (ET), but some patients do not respond well due to side effects or from loss of the effect of stimulation over time. The caudal zona incerta (ZI) has emerged as a promising target in ET, and the effects of ZI-DBS on PD tremor are less studied. Here, we describe a rare situation in which both ET and PD coexist in a 72-year-old male referred for ZI-DBS due to refractory tremor. The aim of this study was to evaluate whether there was a difference in the area stimulated to improve each type of tremor and whether tractography could improve and predict motor outcome. METHODS: Two months after the surgery, in order to define which of the cathodes was the most effective towards improving the tremor and parkinsonian symptoms, a double-blinded, monopolar evaluation was conducted on both hemispheres separately. Once the best contact and parameters were defined, the volume of tissue activation (VTA) was represented spatially for each type of tremor and, finally, the image model was fused with the tractography. RESULTS: For both types of tremor, the hot spot stimulated region achieved the dentato-rubro-thalamic tract (DRTT) at the higher fiber density region. The DRTT fibers were asymmetrical between the right and left hemispheres. CONCLUSION: Regardless of the type of tremor, DRTT can be the most effective region for stimulation. Tractography should be considered when planning the surgical target since the DRTT is not always symmetrical, and the reconstruction of the VTA together with the tractography can greatly improve the DBS programming, and, probably, the patient's outcome to the stimulation.

Mitochondria, which are well known for their critical functions in cellular bioenergetics and metabolism, also serve innate immune purposes by providing specific signaling platforms. Latest advances in our understanding of innate immune receptor-mediated metabolic reprogramming have unraveled specific immune functions of mitochondrial metabolites that place mitochondrial metabolism and particularly the mitochondrial respiratory chain at the center of innate immunity. This review highlights some recent studies that support mitochondrial metabolism as major immune signaling rheostat upon microbe recognition by innate immune cells. PMID- 30286443 TI - Abuse potential assessment of cannabidiol (CBD) in recreational polydrug users: A randomized, double-blind, controlled trial. AB - RATIONALE: Treatment with a highly purified oral solution of cannabidiol (CBD), derived from the plant Cannabis sativa L., demonstrated some evidence of central nervous system (CNS)-related adverse events in patients enrolled in phase 3 trials for treatment of childhood-onset epilepsy. Cannabidiol was categorized as a Schedule 1 substance by the United States Drug Enforcement Administration; therefore, it was important to test CBD for human abuse potential. METHODS: This was a single-dose, randomized, double-blind, double-dummy, placebo- and active controlled crossover trial. The abuse potential of single oral doses of plant derived pharmaceutical formulations of highly purified CBD (Epidiolex(r); 750 mg, 1500 mg, and 4500 mg) was compared with that of single oral doses of alprazolam (2 mg), dronabinol (10 mg and 30 mg), and placebo in healthy recreational polydrug users. The primary endpoint to assess abuse potential was the maximum effect (Emax) on Drug-Liking visual analog scale (VAS). Other measurements included Emax on Overall Drug-Liking VAS, Take Drug Again VAS, positive and negative effects, other subjective effects, and Drug Similarity VAS. Cognitive and psychomotor functions were assessed using the Divided Attention Test, the Hopkins Verbal Learning Test-Revised, and the Digit-Symbol Substitution Task. Pharmacokinetic parameters were determined for CBD and its major metabolites. Standard safety measures and adverse events were assessed. PRINCIPAL RESULTS: Of 95 eligible subjects, 43 qualified for the treatment phase, received at least 1 dose of investigational medicinal product, and were included in safety assessments; 35 subjects were included in the pharmacodynamic analysis. Subjects receiving alprazolam and dronabinol had significantly higher Drug-Liking Emax (P < 0.0001) compared with those receiving placebo, confirming study validity. Compared with placebo, Drug-Liking was not significantly different for subjects taking 750-mg CBD (P = 0.51). Drug-Liking Emax values for 1500-mg and 4500-mg CBD were significantly different from placebo (P = 0.04 and 0.002, respectively); however, the mean differences were <10 points on VAS compared with >18-point differences between positive controls and placebo. Alprazolam and dronabinol had significantly higher Drug-Liking, Overall-Liking, and Take Drug Again VAS Emax values compared with all doses of CBD (P <= 0.004). In contrast to alprazolam, CBD administration had no observable effect on cognitive/psychomotor tests. Pharmacokinetic parameters for CBD in this trial were consistent with previous studies. The majority of adverse events reported during the trial were of mild or moderate severity; no serious adverse events or deaths were reported. CONCLUSION: Administration of a therapeutic dose of CBD (750 mg) showed significantly low abuse potential in a highly sensitive population of polydrug users. Although high and supratherapeutic doses of CBD (1500 mg and 4500 mg, respectively) had detectable subjective effects compared with placebo; the effects were significantly lower than those observed with alprazolam and dronabinol.

PMID- 30286447 TI - The Gut Microbiota and Hematopoietic Stem Cell Transplantation: Challenges and Potentials. AB - The human gut microbiota gained tremendous importance in the last decade as next generation technologies of sequencing and multiomics analyses linked the role of the microbial communities to host physiology and pathophysiology. A growing number of human pathologies and diseases are linked to the gut microbiota. One of the main mechanisms by which the microbiota influences the host is through its interactions with the host immune system. These interactions with both innate and adaptive host intestinal and extraintestinal immunity, although usually commensalistic even mutualistic with the host, in some cases lead to serious health effects. In the case of allogenic hematopoietic stem cell transplantation (allo-HSCT), the disruption of the intestinal microbiota diversity is associated with acute graft-versus-host disease (GvHD). Causing inflammation of the liver, skin, lungs, and the intestine, GvHD occurs in 40-50% of patients undergoing allo HSCT and results in significant posttransplantation mortality. In this review, we highlight the impact of the gut microbiota on the host immunity in GvHD and the potential of microbiota in alleviation or even prevention of GvHD. PMID- 30286445 TI - Racial discrimination, educational attainment, and biological dysregulation among midlife African American women. AB - OBJECTIVE: To examine the association between self-reported racial discrimination and allostatic load, and whether the association differs by socioeconomic position. METHODS: We recruited a purposive cross-section of midlife (ages 30-50) African American women residing in four San Francisco Bay area counties (n = 208). Racial discrimination was measured using the Experience of Discrimination scale. Allostatic load was measured as a composite of 15 biomarkers assessing cardiometabolic, neuroendocrine, and inflammatory activity. We calculated four composite measures of allostatic load and three system-specific measures of biological dysregulation. Multivariable regression was used to examine associations, while adjusting for relevant confounders. RESULTS: In the high education group, reporting low (b = -1.09, P = .02, 95% CI = -1.99, -0.18) and very high (b = -1.88, P = .003, 95% CI = -3.11, -0.65) discrimination was associated with lower allostatic load (reference=moderate). Among those with lower education, reporting low (b = 2.05, P = .008, 95% CI = 0.55,3.56) discrimination was associated with higher allostatic load. Similar but less consistent associations were found for poverty status. Associations were similar for cardiometabolic functioning, but not for neuroendocrine or inflammatory activity. CONCLUSIONS: Racial discrimination may be an important predictor of cumulative physiologic dysregulation. Factors associated with educational attainment may mitigate this association for African American women and other groups experiencing chronic social stress. PMID- 30286448 TI - Clinical Features and Prognosis of Nontuberculous Mycobacterial Pleuritis. AB - BACKGROUND: While nontuberculous mycobacterial (NTM) pleuritis rarely complicates pulmonary NTM infection, high mortality has been reported in case reports and small studies. OBJECTIVES: The purpose of this study was to clarify the clinical features and treatment outcomes of pulmonary NTM infection cases accompanied by NTM pleuritis. METHODS: Medical records of 1,044 patients with pulmonary NTM disease were retrospectively reviewed to select patients complicated by NTM proven pleuritis. We investigated clinical characteristics, pathogens, pleural effusion examinations, radiographic findings, treatments, and clinical course of the NTM pleuritis patients. RESULTS: Among 1,044 cases with pulmonary NTM, NTM pleuritis occurred in 15 cases (1.4%). The mean age was 69 years with a performance status of mostly 2 or better (80.0%), and 6 cases (40.0%) were complicated by pneumothorax. Subpleural cavities were radiologically detected in 11 cases (73.3%), and extrapulmonary air-fluid level was detected in 14 cases (93.3%). Eleven patients were treated with combinations of 2-4 antimycobacterial drugs, including clarithromycin, and 2 patients were treated with isoniazid, rifampicin, and ethambutol. Chest tube drainage was performed in 11 cases, and surgical approach was added in 6 cases. The pleural effusion of 2 patients treated with only antimycobacterial medications gradually deteriorated. Two patients died from NTM pleuritis, and 1 patient died from pneumonitis during a mean of 1.8 years of follow-up. CONCLUSIONS: Comorbid NTM pleuritis was difficult to treat by medical therapy alone and resulted in a poor prognosis. In addition to antimycobacterial agents, chest tube drainage and surgical procedures in the early stages should be considered to treat NTM pleuritis. PMID- 30286449 TI - Pancreatic Thyrotropin Releasing Hormone and Mechanism of Insulin Secretion. AB - Thyrotropin releasing hormone (TRH; pGlu-His-ProNH2) is expressed also in pancreatic beta cells where it is colocalized in secretory granules with insulin. High perinatal changes of the TRH gene expression and TRH concentrations in rat pancreatic islets coincide with the perinatal maturation of the adequate insulin secretory responsiveness to glucose and other nutrient secretagogues. TRH secretion from pancreatic islets is stimulated by glucose and inhibited by insulin. Disruption of the TRH gene in knockout mice results in hyperglycemia accompanied by impaired insulin secretory response to glucose. Progress in understanding TRH - insulin relations may be substantial for improving knowledge of pathophysiological mechanisms included in changes of insulin secretion with possible clinical impact. Block of the last step of biosynthesis of alpha amidated peptides, including TRH by disulfiram (DS) treatment of adult male rats subcutaneously with 200 mg/kg for five days in our experiments resulted in barely detectable levels of peptidyl-glycine alpha-amidating monooxygenase (PAM) in their pancreatic islets. TRH in physiological concentration (1 nM) does not affect basal insulin secretion from intact rat pancreatic islets. In contrast, basal insulin secretion from islets of DS-treated rats is four times higher compared to controls and could not be further stimulated by high-glucose. The addition of 1 nM TRH into medium decreased immediately basal insulin secretion in DS (TRH lacking) islets to control level and normalized also their response to glucose. Interestingly, absence of the secretory response to glucose in islets from TRH depleted rats was connected with their increase of insulin content during stimulation. Glucose stimulation together with 1 nM TRH normalized also insulin content in DS islets. Apparently, high insulin content in islets from TRH depleted animals is a result of block of regulatory secretion pathway redirected to constitutional secretion which was corrected by the addition of TRH. Type 2 diabetes mellitus is a disease characterized by various range from predominant insulin resistance with relative insulin deficiency to a predominant secretory defect with insulin resistance. These symptoms suggest a possible role of TRH dysregulation. In conclusion, presence of TRH in beta cells ensures appropriate low basal (constitutive) insulin secretion. Release of TRH induced by glucose and possibly by other secretagogues has autocrine effect resulting in directing insulin secretion to regulatory pathway reacting to stimulation. If some defects of insulin secretion could be treated by TRH, various ways of applications (also oral and nasal) could be utilized. Moreover, positive side effects shown in animal experiments may accompany the treatment: TRH has the potential to prevent apoptosis and promotes insulin-producing cell proliferation and has also aging reversing properties. PMID- 30286451 TI - Blood Pressure Seasonality in Hemodialysis Patients from Five European Cities of Different Latitudes. AB - BACKGROUND/AIMS: Climate influences the regulation of blood pressure (BP). Our objective was to precisely estimate BP seasonality in hemodialysis (HD) patients from five European cities with marked climate differences. METHODS: Stable prevalent HD patients from 5 European facilities (Santa Cruz de Tenerife (Spain), Seville (Spain), Montpellier (France), Ottignies (Belgium), Umea (Sweden)) present over the years 1995-1999 were included in this historical longitudinal observational study. Individual monthly averages of pre-dialysis BP level were computed from all facility BP measurements (> 90 000 observations). The association between BP level and location, seasons and meteorological measurements was analyzed by mixed models. RESULTS: 261 patients were included and followed-up for a median duration of 2 years (6903 monthly observations). Pre dialysis SBP and DBP were minimal in summer (July) and maximal in winter (November and December), and mean changes were respectively 4.2 [3.0; 5.4] and 2.0 [1.3; 2.7] mmHg. Seasonality was confirmed in 4 locations (Pseason<=0.001 for SBP and DBP), but not in Umea (both Pseason> 0.05). Seasonal changes in DBP were larger in southern locations (Pinteraction=0.02). BP level was associated with climate parameters: in a positive manner with humidity or rainfall, and inversely with sunshine duration or temperature. The effects of temperature and rainfall on DBP varied with latitude (Pinteraction< 0.02) and were greater in southern locations. CONCLUSION: BP varies with seasons and climate in different European areas and seasonality can be more important in southern locations. These changes in BP deserve attention as they may be responsible for a significant increase in cardiovascular risk which may be preventable. PMID- 30286450 TI - Zinc Supplementation Attenuates Cardiac Remodeling After Experimental Myocardial Infarction. AB - BACKGROUND/AIMS: The objective of our study was to evaluate the effects of zinc supplementation on cardiac remodeling following acute myocardial infarction in rats. METHODS: Animals were subdivided into 4 groups and observed for 3 months: 1) Sham Control; 2) Sham Zinc: Sham animals receiving zinc supplementation; 3) Infarction Control; 4) Infarction Zinc. After the followup period, we studied hypertrophy and ventricular geometry, functional alterations in vivo and in vitro, changes related to collagen, oxidative stress, and inflammation, assessed by echocardiogram, isolated heart study, western blot, flow cytometer, morphometry, and spectrophotometry. RESULTS: Infarction induced a significant worsening of the functional variables. On the other hand, zinc attenuated both systolic and diastolic cardiac dysfunction induced by infarction. Considering the infarct size, there was no difference between the groups. Catalase and superoxide dismutase decreased in infarcted animals, and zinc increased its activity. We found higher expression of collagens I and III in infarcted animals, but there was no effect of zinc supplementation. Likewise, infarcted animals had higher levels of IL-10, but without zinc interference. Nrf-2 values were not different among the groups. Infarction increased the amount of Treg cells in the spleen as well as the amount of total lymphocytes. Zinc increased the amount of CD4+ in infarcted animals, but we did not observe effects in relation to Treg cells. CONCLUSION: zinc attenuates cardiac remodeling after infarction in rats; this effect is associated with modulation of antioxidant enzymes, but without the involvement of collagens I and III, Nrf-2, IL-10, and Treg cells. PMID- 30286452 TI - Partial 5p Deletion and Partial 5q Duplication in a Patient with Multiple Congenital Anomalies: A Two-Step Mechanism in Chromosomal Rearrangement Mediated by Non-Allelic Homologous Recombination. AB - We describe a 5-month-old female who presented with clinical features of 5p deletion syndrome, including high-pitched cry, microcephaly, micrognathia, bilateral preauricular tags, bifid uvula, abnormal palmar creases, bilateral hypoplastic nipples, feeding difficulties, and developmental delay. In addition, the patient also had a cardiac defect, proximal esophageal atresia, and distal tracheoesophageal fistula. aCGH of the patient revealed a 22.9-Mb deletion of chromosome 5p15.33p14.3 and an 8.28-Mb duplication of chromosome 5q12.1q13.2. Parental chromosome analysis indicated that these alterations are de novo. Chromosome and FISH analysis demonstrated that the 5q12.1q13.2 duplicated segment was attached to the 5p14.3 region with the band 5q12.1 more distal to the centromere than the band 5q13.2. Based on the bioinformatic analysis, we postulate a mechanism for the formation of this complex rearrangement of chromosome 5 by 2-step-wise events mediate by nonallelic homologous recombination between low copy repeats. To the best of our knowledge this rearrangement found in our patient has not been reported in the literature. This report demonstrates the value of chromosome analysis in conjunction with FISH and aCGH for identification of complex rearrangements which cannot be revealed by array analysis alone. PMID- 30286453 TI - A Challenging Prenatal QF-PCR Rapid Aneuploidy Test Result Caused by a Maternally Inherited Triplication within Chromosome Xq26.2. AB - The aim of this study was to investigate the origin of the biallelic trisomic amplification pattern of the X chromosome microsatellite marker DXS1187 in an otherwise normal male fetus, identified on routine rapid aneuploidy detection (RAD) testing by quantitative fluorescent-polymerase chain reaction (QF-PCR). Amniocentesis was performed on a 35-year-old female at 15 weeks, 2 days gestation for a positive first trimester screen. QF-PCR, metaphase FISH, and chromosomal microarray were carried out on both maternal and fetal DNA. Fetal QF-PCR showed a biallelic trisomic pattern for the X chromosome microsatellite marker DXS1187, with an otherwise normal male amplification pattern at all other sex chromosome markers. Chromosome analysis performed on cultured amniocytes showed a normal male karyotype. Chromosome microarray analysis identified a maternally inherited 304-kb copy number triplication within chromosome Xq26.2 encompassing the DXS1187 marker. The maternally inherited X chromosome harbors an apparently tandem 304-kb triplication that overlaps the DXS1187 marker. As the triplicated region is devoid of clinically relevant genes, it was considered as likely benign in the fetus. Postnatal follow-up reported a healthy male newborn. To our knowledge, this is a unique case demonstrating a "benign" copy number imbalance involving the DXS1187 marker detected by prenatal QF-PCR RAD. PMID- 30286454 TI - Chronic Fatigue Syndrome: From Chronic Fatigue to More Specific Syndromes. AB - In the last decade, a group of chronic disorders associated with fatigue (CDAF) emerged as the leading cause of chronic fatigue, chronic pain, and functional impairment, all of which have been often labeled in clinical practice as chronic fatigue syndrome (CFS) or fibromyalgia. While these chronic disorders arise from various pathophysiologic mechanisms, a shared autoimmune or immune-mediated etiology could shift the focus from symptomatic treatment of fatigue and pain to targeted immunomodulatory and biological therapy. A clinical paradigm shift is necessary to reevaluate CFS and fibromyalgia diagnoses and its relationship to the CDAF entities, which would ultimately lead to a change in diagnostic and therapeutic algorithm for patients with chronic fatigue and chronic pain. Rather than uniformly apply the diagnoses of CFS or fibromyalgia to any patient presenting with unexplained chronic fatigue or chronic pain, it may be more beneficial and therapeutically effective to stratify these patients into more specific diagnoses in the CDAF group. PMID- 30286455 TI - Megestrol Acetate Induces Declarative Memory Changes and Cortisol Suppression in Healthy Volunteers. AB - BACKGROUND: The effects of the glucocorticoid and progesterone receptor agonist megestrol on declarative memory, and the ability of phenytoin to block these effects, were assessed. METHODS: Healthy volunteers received each medication combination (placebo and megestrol, phenytoin and megestrol, and placebo and placebo) using a randomized, crossover design. The Rey Auditory Verbal Learning Test assessed declarative memory. RESULTS: Megestrol was associated with a significant reduction in declarative memory (p = 0.0008), which was attenuated by phenytoin, and was associated with significant cortisol suppression compared to placebo (p < 0.001). CONCLUSION: Changes in memory and cortisol suppression were found in healthy volunteers given megestrol. PMID- 30286456 TI - Cytologic Features of SMARCA4-Deficient Thoracic Sarcoma: A Case Report and Comparison with Other SWI/SNF Complex-Deficient Tumors. AB - BACKGROUND: SMARCA4-deficient thoracic sarcoma is a recently proposed entity of soft tissue tumors associated with an extremely poor prognosis. Its cytologic features have not been well described in the literature yet. CASE: A woman in her early 30s who presented with chest pain was found to have a tumor in the right chest wall. Cytologic smears revealed numerous atypical round-to-polygonal cells appearing singly or in loosely cohesive clusters. These cells had a well-defined cell border, scant-to-moderate cytoplasm, and enlarged vesicular nuclei with prominent nucleoli. In addition, some cells with eosinophilic globular intracytoplasmic inclusions and eccentrically located nuclei, consistent with rhabdoid cells, were observed. Immunocytochemically, the cells were at least focally positive for cytokeratin CAM5.2 and CD34 and showed a significantly reduced BRG1/SMARCA4 expression. The diagnosis was confirmed by histological, immunohistochemical, and genetic analysis of a metastatic lesion to the left axillary lymph node. CONCLUSION: Although the cytologic features of SMARCA4 deficient thoracic sarcoma are not fully unique, they are sufficiently characteristic to suspect this tumor in cases of supporting clinical and radiological features, which may promote additional immunological or molecular testing to establish a definitive diagnosis. PMID- 30286457 TI - Radial Endobronchial Ultrasound Greyscale Texture Analysis Using Whole-Lesion Analysis Can Characterise Benign and Malignant Lesions without Region-of-Interest Selection Bias. AB - BACKGROUND: Radial-probe endobronchial ultrasound (RP-EBUS) is predominantly used clinically for the localisation of peripheral pulmonary lesions prior to biopsy. However, the RP-EBUS image itself contains information that can characterise the aetiology of lesions. OBJECTIVES: The aim of this study was to show the utility of RP-EBUS image analysis using unconstrained regions of interest (ROIs) that utilise more image information and eliminate ROI selection bias. METHODS: We developed custom software to analyse RP-EBUS images digitally captured during clinical procedures. Unconstrained ROIs were mapped onto lesions. We computed first-order greyscale image statistics of minimum, maximum, mean, standard deviation and range of pixel intensities, and entropy. We also computed second order greyscale texture features of contrast, correlation, energy and homogeneity. The results of image analysis were compared to gold-standard tissue diagnosis. Features from expert- and non-expert-defined ROIs were also compared. RESULTS: Eighty-five images were analysed (38 benign and 47 malignant). Five greyscale features were significantly different between benign and malignant lesions. Benign lesions had higher mean (p < 0.01) and maximal (p < 0.001) intensity, greater range (p < 0.001) of pixel intensities and greater entropy (p < 0.01). The highest positive predictive values were associated with maximal (87.8%) and range of pixel (83.8%) intensities. There were no significant differences between expert- and non-expert-defined ROIs. CONCLUSION: RP-EBUS image analysis using unconstrained ROIs eliminates ROI selection bias and can characterise benign and malignant lesions with an accuracy of up to 85%. PMID- 30286458 TI - Energy (Im-)Balance in Frugivorous Lemurs in Southern Madagascar: A Preliminary Study in Lemur catta and Eulemur rufifrons * collaris. AB - The reproductive cycle of several lemur species is synchronized by photoperiodic changes and it is attuned to the seasonal fluctuations in food supply. Nevertheless, irregular periods of food shortage occur in Madagascar, which can result in a negative energy balance and reduced fitness, especially in frugivorous species. Here, we tested whether ring-tailed lemurs (Lemur catta) and brown lemurs (Eulemur rufifrons * collaris) use fat stores to maintain their energy balance in a gallery forest of Madagascar (Berenty Reserve). We assessed the energy intake from weight-based estimates of food intake (mouthful count) and macronutrient contents in the diet during dry and wet months. The metabolizable energy ingested by these frugivorous/folivorous species was high during the late wet season, but it was insufficient to meet their energy requirements during the dry season. These preliminary data suggest that these lemurs must store sufficient amount of fat mass during the period of food abundance to meet their maintenance requirements and to cope with the energetic burden of the mating season. Estimates based on models assuming no fiber digestibility during the dry season are consistent with the prediction that brown lemurs should supplement their daytime diet with nighttime feeding in addition to the use of body fat stores. PMID- 30286459 TI - Impact of the Choice of IGF-I Assay and Normative Dataset on the Diagnosis and Treatment of Growth Hormone Deficiency in Children. AB - BACKGROUND: The analysis of insulin-like growth factor I (IGF-I) is an important tool for pediatricians in the diagnosis and treatment of growth hormone deficiency in children. However, significant differences exist in IGF-I assays and normative datasets, which can have important clinical consequences. METHODS: IGF-I analyses were performed using the IDS-iSYS platform on 1,897 samples from pediatric patients (0.5-18 years old). Z-scores were calculated based on normative IGF-I data from Bidlingmaier et al. (SD-BM) [J Clin Endocrinol Metab. 2014 May; 99(5): 1712-21] and normative IGF-I data from the IGF-I harmonization program in the Netherlands (SD-NL). The differences in Z-scores were analyzed at relevant clinical decision points (-2 SD, +2 SD). These normative datasets were also compared to normative data reported by Elmlinger et al. [Clin Chem Lab Med. 2004; 42(6): 654-64]. RESULTS: The difference in Z-score between SD-BM and SD-NL was highest in males between 0 and 3 years old, exceeding 2 SD. Clinically relevant discordance between both Z-scores at -2 and +2 SD was found in 12.7% of all samples. The IGF-I levels at -2 and +2 SD reported in the normative dataset of Elmlinger et al. were up to 100% higher than the IGF-I levels reported by Bidlingmaier et al. or the Dutch harmonization program. CONCLUSION: Pediatricians and laboratory specialists should be aware of relevant differences that can exist between IGF-I assays and normative data. Well-defined pediatric reference ranges for the IDS-iSYS platform are highly desirable. PMID- 30286461 TI - Fric Test Revisited: A Suggestion for a New Scoring System and Its Correlation with Urticaria Control Test and Dermatology Life Quality Index. AB - BACKGROUND: Fric test is a useful tool for the diagnosis and threshold testing for symptomatic dermographism. When threshold testing is not available, Urticaria Control Test (UCT) and Dermatology Life Quality Index (DLQI) might be used to assess disease control and quality of life (QoL) impairment, respectively. OBJECTIVES: In this study, we aimed to describe a new scoring system for the Fric test and evaluate the correlations of Fric scores with UCT, DLQI, and other disease activity assessment scores. METHOD: Provocation test with Fric Test 4.0 was performed in all patients at referral and at the 4th week. We considered a 4 grade rating score for Fric Test (0-4) [Total Fric Score (TFS)]. A positive response with all of the four pins suggested severe dermographism (TFS = 4), while a wheal with only the largest pin (4.5 mm) was considered as milder disease (TFS = 1). Treatment responses were evaluated with Fric Test 4.0, UCT, patient's global assessment of disease severity (PatGA-VAS), the physician's global assessment of disease control (PhyGA-VAS), and DLQI at baseline and at the 4th week of treatment. The correlations of TFS with UCT, DLQI, PatGA-VAS, PhyGA-VAS at baseline as well as the changes in the mean scores after treatment (week 4) were performed. RESULTS: The mean UCT and DLQI scores were 8.69 +/- 3.40 and 7.88 +/- 6.02 at the first visit. At the second visit, TFS decreased from a mean of 2.79 +/- 1.68 to 1.91 +/- 1.85 (p < 0.001), and UCT scores and PhyGA-VAS were increased (p < 0.001), while DLQI scores, PatGA-VAS, and pruritus scores decreased significantly (p = 0.002; p = 0.001; p = 0.012). There was a positive correlation between TFS and pruritus scores (r = 0.378) and DLQI scores (r = 0.392). TFS was found to have a negative correlation with UCT score (r = -0.283) and PhyGA-VAS (r = -0.347). CONCLUSIONS: This new Fric scoring system allows comparison with other tools and shows moderate correlations with most of the tools. Using disease-specific tools is recommended since they provide a subjective evaluation of disease severity, QoL impairment, and disease control. PMID- 30286463 TI - Is Peritoneal Dialysis a Suitable Renal Replacement Therapy Option for Polycystic Kidney Disease Patients? AB - BACKGROUND/AIMS: Mounting clinical experience and evidence from scale observational studies have suggested that polycystic kidney disease (PKD) was not a contraindication for peritoneal dialysis (PD). Recent studies have reported that PD may be associated with a better prognosis in PKD than that of non-PKD patients. To solve the problem, we performed a systematic review and comprehensive meta-analysis to compare the outcomes between PKD and non-PKD patients on PD and the all-cause mortality between patients with PKD on PD and hemodialysis (HD). METHODS: We conducted a systematic literature using electronic databases (PubMed, Ovid, Embase and Web of Science) to identify the studies reporting the endpoint events of PKD/non-PKD patients with PD and the all-cause mortality between patients with PKD on PD and HD, such as dialysis adequacy, technique failure, PD-related complications, the mode of RRT change, and all cause mortality. We searched the literature published February 2018 or earlier. We used both fix-effects and random-effects models to calculate the overall effect estimate. A sensitivity analysis and subgroup analysis were performed to find the origin of heterogeneity. RESULTS: 12 studies with a total of 17,040 patients reported the endpoint events of PKD/non-PKD patients with PD. No significant difference was observed on dialysis adequacy (Kt/V, SMD: -0.02, 95%CI: -0.12-0.08; D: Pcr (4h), SMD: -0.10, 95% CI: -0.26-0.06), technique failure (RR: 0.97, 95%CI: 0.78-1.20), RRT change (RR: 0.96, 95%CI: 0.77-1.19), total PD-associated complications (RR: 1.0, 95%CI: 0.91-1.09) and all-cause mortality (RR: 0.40, 95%CI: 0.33-0.47) in PKD patients, compared with non-PKD subjects undergoing PD. However, the proportion of renal transplantation in PKD patients was higher than that of non-PKD patients (RR: 2.04, 95%CI: 1.88-2.20) with significant heterogeneity (I2 =82.7%, P=0.000). 4 studies with a total of 5,762 patients reported that the all-cause mortality did not differ between the PKD patients on PD and HD (RR: 0.87, 95%CI: 0.72-1.06). CONCLUSION: Our meta analysis found that the outcomes of given population of PKD patients on PD were at least not inferior as compared to those with other primary kidney diseases, and suggested that PKD might be not absolutely a contraindication for PD. Given the limitations of the proposed, it needs further large-scale studies to assess whether PD is a suitable RRT option for end-stage renal disease (ESRD) patients with PKD.

PMID- 30286462 TI - Long Non-Coding RNA H19 Regulates Human Lens Epithelial Cells Function. AB - BACKGROUND/AIMS: Age-related cataract (ARC) remains the leading cause of visual impairment among the elderly population. Long non-coding RNAs (lncRNAs) have emerged as potential regulators in many ocular diseases. However, the role of lncRNAs in nuclear ARC, a subtype of ARC, requires further elucidation. METHODS: LncRNA sequencing was performed to identify differentially expressed lncRNAs between the capsules of transparent and nuclear ARC lenses. Expression validation was confirmed by qRT-PCR. MTT assay, Calcein-AM and propidium iodide double staining, Rhodamine 123 and Hoechst double staining, EdU and transwell assay were used to determine the role of H19 or miR-675 in the viability, apoptosis, proliferation and migration of primary cultured human lens epithelial cells (HLECs). Bioinformatics and luciferase reporter assays were used to identify the binding target of miR-675. RESULTS: Sixty-three lncRNAs are differentially expressed between the capsules of transparent and nuclear ARC lenses. One top abundantly expressed lncRNA, H19, is significantly up-regulated in the nuclear ARC lens capsules and positively associated with nuclear ARC grade. H19 knockdown accelerates apoptosis development and reduces the proliferation and migration of HLECs upon oxidative stress. H19 is the precursor of miR-675, and a reduction of H19 inhibits miR-675 expression. miR-675 regulates CRYAA expression by targeting the binding site within the 3'UTR. Moreover, miR-675 increases the proliferation and migration while decreasing the apoptosis of HLECs upon oxidative stress. CONCLUSION: H19 regulates HLECs function through miR-675-mediated CRYAA expression. This finding would provide a novel insight into the pathogenesis of nuclear ARC. PMID- 30286465 TI - Exposure to Environmental Tobacco Smoke and Prevalence of Atopic Dermatitis among Adolescents in Kuwait. AB - BACKGROUND: This study aimed to (i) assess the prevalence of exposure to environmental tobacco smoke (ETS) at homes, (ii) assess the prevalence of atopic dermatitis and (iii) evaluate the association between ETS exposure and atopic dermatitis status among adolescents. METHODS: During October 2015, a cross sectional study design was implemented using a self-administered, modified version of the ISAAC (International Study of Asthma and Allergies in Childhood) questionnaire among students enrolled in nine high schools of one of the six governorates of Kuwait. Prevalence of ETS exposure at home (1 or more smokers at home vs. none) and atopic dermatitis were computed. A multivariable log-binomial regression model was used to evaluate the adjusted association between ETS exposure and atopic dermatitis. RESULTS: Of 800 invited students, 746 (93.3%) participated, of whom 74.8% were Kuwaiti and 50.1% were female with a mean (SD) age of 16.8 (0.68) years. Prevalence of ETS exposure at home was 54%. Prevalence of atopic dermatitis was 14.9%. A final multivariable log-binomial regression model showed that compared with the adolescents free from atopic dermatitis, adolescents with atopic dermatitis were significantly more likely to have had ETS exposure at home (adjusted prevalence ratio = 1.49; 95% CI: 1.03-2.14; p = 0.034) or tended to be female (adjusted prevalence ratio = 1.42; 95% CI: 0.99-2.03; p = 0.054). CONCLUSIONS: A high prevalence of ETS exposure at home among adolescents was recorded. ETS exposure and female gender were significantly associated with atopic dermatitis status. Intervention fostering voluntary adoption of a smoke free home rule may help protect the adolescents against ETS exposure and alleviate the menace of associated morbidity. PMID- 30286466 TI - Utility of Regular Management of Physical Activity and Physical Function in Hemodialysis Patients. AB - BACKGROUND/AIMS: Several clinical practice guidelines recommend regular assessment of physical activity and physical function as part of routine care in hemodialysis patients. However, there is no clear evidence to support these recommendations. We investigated whether the proportion of attendance at a regular program for management of physical activity and physical function can predict all-cause mortality and cardiovascular events in hemodialysis patients. METHODS: This retrospective cohort study consisted of 266 hemodialysis patients participating in the management program at least once. Participants were tracked for 3 years after their first attendance at the management program to determine their attendance proportion. The main study outcomes included all-cause mortality and a composite of fatal and nonfatal cardiovascular events. RESULTS: Median patient age was 64.5 (interquartile range, 56.8 - 72.0) years, 45% were women, and the median time on hemodialysis was 35.5 (interquartile range, 12.0 - 114.3) months at baseline. Sixty-five patients died over a median follow-up of 79 months. The incidence of cardiovascular events was 60 over a median follow-up of 68 months. Even after adjusting for any of the prognostic models, participants who attended <= 75% of sessions (n = 140) had higher risks of mortality (hazard ratio (HR), 1.79; 95% confidence interval (CI): 1.00 - 3.36; P = 0.049) and cardiovascular events (HR, 1.84; 95% CI: 1.07 - 3.48; P = 0.03) than those attending > 75% of sessions (n = 126). CONCLUSION: Hemodialysis patients in whom physical activity and physical function could be assessed more regularly had better prognosis than those with only intermittent assessment. PMID- 30286468 TI - Is Early Complement Activation in Renal Transplantation Associated with Later Graft Outcome? AB - BACKGROUND/AIMS: Complement activation is important in post-transplantation renal injury, but data on its role as predictor of transplant outcome/complications when assessed in donor kidneys are lacking. METHODS: In human renal transplant biopsies with delayed graft function (DGF, n=12), antibody mediated rejection (ABMR, n=8), T-cell mediated rejection (TCMR, n=11), 1 year protocol biopsies (control, n=10) and corresponding zero-biopsies we performed immunohistochemical analyses of 6 complement factors using FFPE sections and correlated the findings with kidney function, as assessed by serum creatinine, and morphological changes including interstitial fibrosis and tubular atrophy (IF/TA). RESULTS: In DGF, TCMR and ABMR significant complement deposition was observed, which was less pronounced in corresponding zero-biopsies. Zero-biopsies with subsequent ABMR showed glomerular complement factor D and C3c expression. Moreover, glomerular C3c and C9 and tubular MASP-2 and Collectin-11 expression in zero-biopsies significantly correlated with serum creatinine at diagnosis of DGF, TCMR or ABMR. Glomerular C1q was significantly increased in ABMR, but not in DGF and TCMR. In contrast, peritubular C1q was significantly enhanced in DGF and TCMR compared to zero-biopsies. Using C3d as a surrogate marker for complement activity we could confirm that stained complement factors are frequently associated with complement activity. CONCLUSION: Complement deposition strongly correlated with histopathological changes observed in renal transplants. All 3 complement pathways were operational in biopsies with DGF, TCMR and ABMR albeit with differential abundance and localization. Since complement deposition in zero biopsies correlated with graft function and morphological changes, early specific complement inhibition in renal transplantation may be a new therapeutic option to prevent graft loss. PMID- 30286467 TI - Omi/HtrA2 Regulates a Mitochondria-Dependent Apoptotic Pathway in a Murine Model of Septic Encephalopathy. AB - BACKGROUND/AIMS: the pathogenesis of sepsis-associated encephalopathy (SAE) is multifactorial, involving neurotransmitter alterations, inflammatory cytokines, oxidative damage, mitochondrial dysfunction, apoptosis, and other factors. Mitochondria are major producers of reactive oxygen species, resulting in cellular injury. Omi/HtrA2 is a proapoptotic mitochondrial serine protease involved in caspase-dependent cell death; it is translocated from mitochondria to the cytosol after an apoptotic insult. We previously found that UCF-101, a specific inhibitor of Omi/HtrA2, has neuroprotective effects on cerebral oxidative injury and cognitive impairment in septic rats. In this study, the mechanisms and molecular pathways underlying these effects were investigated. METHODS: Male Sprague-Dawley rats were subjected to cecal ligation and puncture (CLP) or sham-operated laparotomy and were administered vehicle or UCF-101 (10 umol/kg). The hippocampus was isolated for subsequent analysis. Omi/HtrA2 expression in the mitochondria or cytosol was evaluated by immunofluorescence or western blotting. Terminal deoxynucleotidyl transferase dUTP nick end labeling staining was utilized to evaluate levels of apoptosis, and western blotting was used to evaluate apoptosis-related proteins, such as cleaved caspase-3, caspase 9, and poly (ADP-ribose) polymerase (PARP). Tight junction expression was assessed by immunofluorescence and western blotting. Mitochondrial function, inflammatory cytokines, and oxidative stress were also assayed. In addition, a wet/dry method was used to evaluate brain edema and Evans blue extravasation was used to evaluate blood-brain barrier (BBB) integrity. RESULTS: After CLP treatment, the hippocampus exhibited a mild increase in Omi/HtrA2 expression; cytosolic Omi/HtrA2 expression increased significantly, whereas mitochondrial Omi/HtrA2 expression was reduced, indicating that CLP-induced oxidative stress resulted in the translocation of Omi/HtrA2 from mitochondria to the cytosol. Hippocampal cleaved caspase-3, caspase-9, and PARP levels were significantly higher in animals treated with CLP than in sham-operated animals, while XIAP expression was lower. Treatment with UCF-101 prevented the mobilization of Omi/HtrA2 from mitochondria to the cytosol, attenuated XIAP degradation, and decreased cleaved caspase-3, caspase-9, and PARP expression as well as apoptosis. UCF-101 also reversed the decreased mitochondrial complex I, II, and III respiration and the reduced ATP caused by CLP. In addition, UCF-101 treatment resulted in a significant improvement in BBB integrity, as demonstrated by increased occludin, claudin-5, and zonula occludens 1 levels and reduced Evans blue extravasation. No significant effects of UCF-101 on brain edema were found. Inflammatory cytokines and oxidative stress were significantly higher in the CLP treated group than in the sham-operated group. However, the inhibition of Omi/HtrA2 by UCF-101 significantly alleviated these responses. CONCLUSION: Our data indicated that Omi/ HtrA2 regulates a mitochondria-dependent apoptotic pathway in a murine model of septic encephalopathy. Inhibition of Omi/HtrA2 by UCF-101 leads to neuroprotection by inhibiting the cytosolic translocation of Omi/HtrA2 and antagonizing the caspase-dependent apoptosis pathway. Therapeutic interventions that inhibit Omi/HtrA2 translocation or protease activity may provide a novel method to treat SAE. PMID- 30286470 TI - Editorial Board / Contents / Imprint. PMID- 30286469 TI - MicroRNA-29a Inhibits Growth, Migration and Invasion of Melanoma A375 Cells in Vitro by Directly Targeting BMI1. AB - BACKGROUND/AIMS: Melanoma is one of the most aggressive malignant tumors, with increasing incidence, poor prognosis, and lack of any effective targeted therapies. Abnormal expression of miR-29a has been found in several types of cancers, including melanoma. In this study, experiments were performed to investigate the role of miR-29a in melanoma, and the molecular mechanism by which miR-29a represses melanoma. METHODS: miR-29 and Bmi1 expression was examined by quantitative real-time polymerase chain reaction (qRT-PCR). The cell viability, apoptosis, migration and invasion were respectively determined by Cell Counting Kit-8 assay, Propidium iodide (PI) fluorescein isothiocynate (FITC)-Annexin V staining assay, wound healing assay and transwell assay. Luciferase reporter assay was performed to determine a target gene of miR-29a. Western blot was used to analyze protein expression of apoptosis-related proteins, Bmi1, Wnt/beta catenin and Nuclear factor-kappaB (NF-kappaB) pathway target genes. RESULTS: miR 29a was down-regulated in all tested melanoma cell lines. Up-regulation of miR 29a effectively inhibited cell viability, migration, and invasion, but promoted apoptosis in A375 cells. Bmi1 was a direct target gene of miR-29a. Transfection with miR-29a mimic decreased cell migration and invasion and Bmi1 expression in Malme-3M cells, SK-MEL-2, SK-MEL-5, and M14 cell lines. Moreover, miR-29a might suppress growth, migration and invasion of A375 cells by negatively regulating Bmi1. In addition, our results demonstrated that transfection with miR-29a mimic effectively blocked Wnt/beta-catenin and NF-kappaB pathways via down-regulating Bmi1. CONCLUSION: miR-29a could be functioned as a potential tumor suppressor through direct regulation of Bmi1 in melanoma cells.

PMID- 30286472 TI - Current Therapeutic Options for Pancreatic Ductal Adenocarcinoma. AB - Pancreatic cancer remains the fourth most common cause of cancer-related mortality and is a major health threat. The majority of cases are diagnosed at advanced disease stages, limiting the chances of long-term survival. Several new therapeutic regimens have been introduced into routine clinical practice in recent years and a plethora of novel approaches is currently undergoing preclinical and early clinical evaluation. This review discusses the current standards of care for systemic therapy of pancreatic cancer and gives a brief outlook on ongoing clinical trials. PMID- 30286474 TI - Erratum. PMID- 30286473 TI - Targeting Defects in the Cellular DNA Damage Response for the Treatment of Pancreatic Ductal Adenocarcinoma. AB - Pancreatic cancer is one of the most common causes of cancer-related mortality in the Western world and pancreatic ductal adenocarcinoma (PDAC) is by far the most common pancreatic cancer entity. Locally advanced or metastatic PDAC remains a major clinical challenge, and the prognosis of affected patients is dismal despite substantial research efforts in this area. Recent large-scale genomic analyses of PDAC revealed that KRAS is the most frequently mutated driver gene in this entity. In addition, a relatively large proportion of PDAC patients displays germline variants in genes involved in DNA repair, particularly DNA double-strand repair. Similarly, a sizable fraction of sporadic PDAC cases harbor mutations in genome maintenance genes, such as BRCA1, BRCA2, and ATM. While direct targeting of oncogenic KRAS is currently not possible in the clinical setting, these defects in DNA repair may open new therapeutic avenues. Here, we discuss the potential use of compounds that interfere with DNA repair and genome maintenance mechanisms for the treatment of PDAC. We particularly focus on the genotype tailored use of compounds, such as PARP inhibitors, as well as ATR- and DNA protein kinase catalytic subunit (PKcs) inhibitors. PMID- 30286475 TI - PharmaNews.

PMID- 30286478 TI - Cell-Free DNA and Neuromediators in Detecting Aggressive Variant Prostate Cancer. AB - BACKGROUND: Aggressive variant transformation in metastatic castration-resistant prostate cancer (mCRPC) represents an under-recognized phenomenon. There is an urgent need for non-invasive biomarkers to detect these variants and identify treatment alternatives. METHODS: A prospective observational pilot study in mCRPC patients receiving treatment with cabazitaxel (CAB) was conducted. Neuromediators were sequentially evaluated and their impact on disease endpoints calculated. Targeted next-generation sequencing (NGS) of cell-free DNA (cfDNA) was also performed in a highly pretreated subset of patients. RESULTS: 23 patients were included. Estimated effects indicate that neuron-specific enolase (NSE) levels at baseline may be correlated with overall survival (NSE unit 18.3 ng/ml: HR1.262 (95% confidence interval (CI) 0.985-1.616)) and that chromogranin A (CGA) may be correlated with progression-free survival (CGA unit 98.1 ng/ml: HR1.341 (95% CI 1.011-1.778)). cfDNA analysis revealed mutations annotated in prostate cancer (PCA) and small cell cancers (SCC). 1 patient showed elevated neuromediators along with annotated mutations in PCA and SCC, potentially indicating aggressive variant cancer. In 3 patients KIT mutations (e.g. pM541L, pV654A) known to be tissue-based biomarkers with level 1 evidence for the treatment with imatinib and sunitinib were found. CONCLUSIONS: Sequential analysis of neuromediators and targeted NGS of cfDNA provide insight for the estimation of tumor heterogeneity under therapy with CAB. PMID- 30286480 TI - Population Genetic Structure of an Endangered Endemic Primate (Leontopithecus chrysomelas) in a Highly Fragmented Atlantic Coastal Rain Forest. AB - This study evaluated the genetic structure of wild populations of the endangered primate, Leontopithecus chrysomelas. We tested the assumption that populations of L. chrysomelas, given their larger population size and a higher degree of habitat continuity, would have higher genetic diversity and less genetic structuring than other lion tamarins. We used 11 microsatellites and 122 hair samples from different locations to assess their genetic diversity and genetic structure, and to make inferences about the isolation by distance. The overall expected heterozygosity (0.51 +/- 0.03) and the average number of alleles (3.6 +/- 0.2) were relatively low, as is the case in other endangered lion tamarins. Genetic clustering analyses indicated two main clusters, whereas the statistical analyses based on genotype similarities and Fst suggested further substructure. A Mantel test showed that only 34% of this genetic differentiation was explained by the linear distance. In addition to linear distance, structural differences in the landscape, physical barriers and behavioural factors may be causing significant genetic structuring. Overall, this study suggests that these populations have a relatively low genetic diversity and a relatively high population genetic structure, putting in question whether the presence of agroforest systems (known locally as cabruca) is enough to fully re-establish functional landscape connectivity. PMID- 30286483 TI - The Effect of Magnesium and Vitamin E Co-Supplementation on Glycemic Control and Markers of Cardio-Metabolic Risk in Women with Polycystic Ovary Syndrome: A Randomized, Double-Blind, Placebo-Controlled Trial. AB - Data on the effects of magnesium and vitamin E co-supplementation on glycemic control and markers of cardio-metabolic risk of patients with polycystic ovary syndrome (PCOS) were collected. This investigation was conducted to evaluate the effects of magnesium and vitamin E co-supplementation on glycemic control and markers of cardio-metabolic risk in women with PCOS. This randomized, double blind, placebo-controlled trial was carried out on 60 women with PCOS, aged 18-40 years old. Participants were randomly divided into two groups to receive 250 mg/day magnesium plus 400 mg/day vitamin E supplements or placebo (n=30 each group) for 12 weeks. Fasting blood samples were taken at baseline and after the 12-week intervention to quantify related variables. After the 12-week intervention, compared with the placebo, magnesium and vitamin E co supplementation led to a significant reduction in serum insulin levels (-1.1+/ 3.0 vs. +1.6+/-3.7 MUIU/ml, p=0.003) and homeostatic model of assessment for insulin resistance (-0.2+/-0.7 vs. +0.4+/-0.9, p=0.002), and a significant increase in the quantitative insulin sensitivity check index (+0.01+/-0.01 vs. 0.009+/-0.02, p=0.003). Furthermore, magnesium plus vitamin E supplementation significantly decreased serum triglycerides (-15.0+/-24.4 vs. +6.7+/-22.2 mg/dl, p=0.001) and VLDL-cholesterol concentrations (-3.0+/-4.9 vs. +0.6+/-2.4 mg/dl, P=0.01) compared with the placebo. A trend toward a greater decrease in total cholesterol levels was observed in magnesium plus vitamin E group compared to placebo group (-7.0+/-32.6 vs. +8.1+/-26.6 mg/dl, p=0.05). In conclusion, magnesium and vitamin E co-supplementation for 12 weeks to PCOS women had beneficial effects on parameters of insulin metabolism and few markers of cardio metabolic risk. PMID- 30286482 TI - Ghrelin Levels in Basal Conditions and During Glucose Tolerance Test in Prediabetic and Diabetic Patients. AB - Ghrelin is associated with glucose homeostasis but its' possible relevance with glucose levels in physiological and pathological conditions has so far been poorly investigated. The aim of the present study was to evaluate circulating ghrelin levels in prediabetic and diabetic patients in basal conditions and in response to oral glucose tolerance test (OGTT). A total of 90 male adults aged 40 - 73 years old were enrolled in our study. Fasting and postprandial plasma ghrelin, insulin and glucose levels were measured at 0, 60, 120 and 180 min following an OGTT in 40 patients with type 2 diabetes mellitus (T2DM), 20 with impaired glucose tolerance (IGT) and 30 controls. Incremental and total area under response curve were determined and calculated for glucose, insulin and ghrelin. Fasting plasma ghrelin concentrations were significantly lower in the T2DM group than IGT and control group patients (p<0.01) but not between healthy subjects and IGT group (p=0.746). In the diabetics' group ghrelin levels showed a statistically significant negative correlation with insulin and a positive correlation with HbA1c and glucose. At all time points after the OGTT ghrelin concentrations were significantly lower in the T2DM group compared to IGT group and controls. Plasma ghrelin concentrations are lower in male diabetic patients at the fasting state and remain lower at all time points after an OGTT while minor differences were found between normal and IGT subjects. Ghrelin might play a role in insulin and glucose metabolism in diabetic patients but not in patients with IGT. PMID- 30286481 TI - Tectonic Proteins Are Important Players in Non-Motile Ciliopathies. AB - Primary cilium is a ubiquitous, tiny organelle on the apex of the mammalian cells. Non-motile (primary) ciliopathies are diseases caused by the dysfunction of the primary cilium and they are characterized by diverse clinical and genetic heterogeneity. To date, nearly 200 genes have been shown to be associated with primary ciliopathies. Among them, tectonic genes are the important causative genes of ciliopathies. Tectonic proteins including TCTN1, TCTN2, and TCTN3 are important component proteins residing at the transition zone of cilia. Indeed, many ciliopathies have been reported to involve tectonics mutations, highlighting a pivotal role for tectonic proteins in ciliary functions. However, the specific functions of tectonic proteins remain largely enigmatic. Herein, we discuss the recent advances on the localization and structure of tectonic proteins and the functions of tectonic proteins. The increasing line of evidences demonstrates that tectonic proteins are required for ciliogenesis and regulate ciliary membrane composition. More importantly, Tectonic proteins play a vital role in the regulation of the Sonic Hedgehog (Shh) pathway; Tectonic deficient mice show the Shh pathway-related developmental defects. Tectonic proteins share similar functions including neural patterning and Gli3 processing but also each has a unique and indispensable role in the ciliogenesis and signaling pathways. At the same time, the mutations of tectonic genes are the causes of a serial of primary ciliopathies including Meckel-Gruber syndrome, Oral-facial-digital syndrome, and Joubert syndrome. Therefore, full understanding of functions of tectonic proteins will help to crack ciliopathies and improve life quality of patients by future gene therapy. PMID- 30286484 TI - Plasma Irisin Levels in Subjects with Type 1 Diabetes: Comparison with Healthy Controls. AB - Irisin is a myokine that increases energy expenditure. In this cross-sectional study, we examined for differences in plasma irisin concentrations between subjects with type 1 diabetes mellitus and healthy individuals and searched for associations between plasma irisin levels and clinical and biochemical characteristics as well as self-reported physical activity. A total of 79 subjects with type 1 diabetes [age 38.2+/-12.5 years, men/women (n): 27/52], were consecutively recruited. Moreover, 53 healthy controls, matched for age and body mass index with those with diabetes were recruited. Plasma irisin was measured with ELISA. Participants were asked about their physical activity during the last week. We also measured trunk and visceral fat. Circulating irisin levels were lower in subjects with diabetes than in controls [median value (interquartile range): 53.0 (35.2, 106.3) vs. 178.1 (42.6, 641.6) ng/ml, respectively, p<0.001]. In the group of diabetes, univariate analysis showed that irisin levels were associated with waist circumference (beta=-0.283, p=0.023), serum triglycerides (beta=-0.282, p=0.031), and trunk fat (beta=-0.324, p=0.012). In multivariate analysis after adjustment for potential confounders, irisin levels were associated independently only with waist circumference (beta=-0.403, p=0.005). Among controls, multivariate analysis demonstrated that irisin levels were associated with pack-years of smoking (beta=-0.563, p=0.012) and fasting triglycerides (beta=-0.338, p=0.041). Circulating irisin levels were lower in subjects with diabetes in comparison with healthy-matched controls. In conclusion, plasma irisin concentrations in subjects with diabetes were associated with waist circumference, while in controls with serum triglycerides and pack-years of smoking. PMID- 30286485 TI - Thyrotropin Receptor Blocking Antibodies. AB - Autoantibodies (Ab) against the thyroid-stimulating hormone receptor (TSHR) are frequently found in autoimmune thyroid disease (AITD). Autoantibodies to the TSHR (anti-TSHR-Ab) may mimic or block the action of TSH or be functionally neutral. Measurement of anti-TSHR-Ab can be done either via competitive-binding immunoassays or with functional cell-based bioassays. Antibody-binding assays do not assess anti-TSHR-Ab functionality, but rather measure the concentration of total anti-TSHR binding activity. In contrast, functional cell-based bioassays indicate whether anti-TSHR-Ab have stimulatory or blocking activity. Historically bioassays for anti-TSHR-Ab were research tools and were used to study the pathophysiology of Graves' disease and Hashimoto's thyroiditis. In the past, bioassays for anti-TSHR-Abs were laborious and time-consuming and varied widely in performance from laboratory to laboratory. Recent advances in the development of cell-based assays, including the application of molecular engineering, have led to significant improvements that have enabled bioassays to be employed routinely in clinical laboratories. The prevalence and functional significance of TSHR blocking autoantibodies (TBAb) in autoimmune hypothyroidism has been less well investigated compared to TSHR stimulating Ab. There is an increasing body of data, however, that demonstrate the clinical utility and relevance of TBAb, and thus the importance of TBAb bioassays, in the diagnosis and management of patients with AITD. In the present review, we summarize the different methods used to measure TBAb, and discuss their prevalence and clinical relevance. PMID- 30286486 TI - Current and Future Treatments for Graves' Disease and Graves' Ophthalmopathy. AB - The course and pathogenesis of Graves' disease and Graves' ophthalmopathy are interdependent, influencing each other's therapeutic choices. Multiple factors including geographic location, access to medical services, patient and physician preferences influence the management of these conditions. Graves' disease is classically managed with one of three treatment options - antithyroid drugs, radioactive iodine, and thyroidectomy. In recent years, there has been a shift towards antithyroid drugs, including long term therapy with these agents, given the advantage of avoiding hypothyroidism and the apparent safety of this approach. In addition, new therapies are (slowly) emerging, focusing on immunomodulation. Technological advances are opening doors to non-pharmaceutical interventions that aim to deal with both structural thyroid abnormalities as well as biochemical abnormalities of hyperthyroidism. Graves' ophthalmopathy management is guided by its activity and severity status, with treatment options including smoking cessation, control of hyperthyroidism, local eye measures, glucocorticoids, selenium, orbital radiotherapy, and surgery. In addition to these established treatment choices, new immunotherapy-based approaches are being tested. Some of them (tocilizumab and teprotumumab) are very promising but further evaluation is needed before we can establish their role in clinical care. Agents identified as beneficial in Graves' disease management will likely be tested in Graves' ophthalmopathy as well. In the coming years, our main clinical responsibility will be to find the proper balance between the benefits and potential risks of these incoming therapies, and to identify the subgroups of patients where this ratio is most likely to favor a safe and successful therapeutic outcome.

AB - Chronic mesenteric ischemia (CMI) is defined by stenoses or occlusions of the celiac artery, superior or inferior mesenteric artery. While it is mostly cause by atherosclerotic disease, less frequent cause in particular in younger patients are fibrowmuscular dysplasia or vasculitis. Risk factors include smoking, hypertension, dyslipidemia, higher age, and female sex. Symptomatic CMI only accounts for less than 5 % of intestinal ischemic events. The prevalence of asymptomatic CMI is unknown but may be as high as 15 % and is more frequent in peripheral artery disease (27 %) and abdominal aortic aneurysm (40 %). The celiac artery is mostly affected. Abdominal pain that is aggravated with food intake with preserved appetite, abdominal bruits, and severe malnutrition can be important clinical hints that raise the suspicion of CMI. The diagnostic modality of choice is duplex ultrasound that should be performed in specialized centers potentially together with functional test causally linking symptoms to relevant arterial stenosis or intestinal ischemia. Typically, a stenosis of only one artery is unlikely to cause CMI. The therapy of choice is revascularization. In most cases angioplasty potentially together with stenting is performed due to low post-interventional mortality in mostly multi-morbid patients with excellent technical and clinical success rates. Non-atherosclerotic CMI in particular in younger patients may require surgery. Similar to the treatment of patients with other cardiovascular diseases, atherosclerosis of mesenteric arteries requires life style modification and optimal medical therapy for risk reduction. Platelet inhibition is indicated after revascularization. PMID- 30286489 TI - [Hyperlipidemia: What role do PCSK9 inhibitors play?] AB - PCSK9 inhibitors are a new and safe option of lowering LDL cholesterol. This article summarizes current recommendations for the use of PCSK9 inhibitors. Statins and ezetimibe are still the basis of cholesterol-lowering therapy. Through their use, the largest proportion of patients can be adequately treated. PCSK9 inhibitors should be used in patients at very high cardiovascular risk if, despite the maximum tolerated statin/ezetimibe therapy, an LDL-C reduction of more than 50 % would be needed to achieve the recommended LDL-C target. The use in patients with familial hypercholesterolemia is usually carried out according to this scheme as well. For statin intolerance, PCSK9 inhibitors should be considered in patients at very high cardiovascular risk who have not tolerated low doses of at least two different statins/ezetimibe. PMID- 30286490 TI - [Nutrition at the End of Life - Ethical Aspects]. AB - Nutritional problems at the end of life are of multifactorial origin, they require an interdisciplinary and multiprofessional approach. A basic precondition in deciding a nutritional therapeutic intervention is a valid medical indication. Fundamental ethical principles have to be respected.Another relevant question is if the nutritional therapeutic intervention will serve a meaningful, attainable goal in accordance with the patient's individual preferences and whether the expected benefit outweighs the potential risks. Particularly in older patients with a higher risk of cognitive impairment there is the question of the patient's ability to communicate his/her personal preferences, if he/she is able to give informed consent.Nutritional problems, particularly the refusal to eat can present a burdensome situation for the patient's carers. The potential reasons and causes for these problems have to be evaluated by an interdisciplinary assessment and medical differential diagnosis. This process has to involve the patient, his family and carers, ethical and palliative care counsel should be available.The topic of artificial feeding by means of a percutaneous gastrostomy its relevance in the end of life situation, particularly in advanced stages of dementia is also addressed. PMID- 30286491 TI - [Medical Treatment of Soft Tissue Sarcoma]. AB - Soft tissue sarcomas are a diagnostically and therapeutically complex disease. This is due to the pronounced heterogeneity, characterized by biologically very different histological subtypes and the resulting clinical progressions. The term encompasses more than 80 different pathologically defined tumors of the soft tissue. Every year, nearly 4000 patients are affected in Germany. The diversity and rarity of the disease make progress difficult. The average 5-year mortality is around 40 %. Therapy is stage-adapted based on size, grading, localization, involvement of lymph nodes or distant metastasis. In the localized situation, surgery is the basis of therapy. Standard is the wide resection. Depending on grading, degree of resection and localization, adjuvant radiotherapy follows in the case of so-called high-risk tumors. Certain very aggressive types (so-called small, blue, round cell sarcomas such as embryonal rhabdomyosarcomas, Ewing tumors, PNET and desmoplastic soft tissue sarcomas (desmoplastic small round cell tumors) are primarily treated with systemic treatment in a multimodality setting. Metastasis surgery is established in isolated pulmonary metastases based on retrospective studies. This article focuses on recent development in treatment of adult type soft tissue sarcoma and GIST. PMID- 30286492 TI - [Shortened duration of antibiotic therapy in bacterial infections]. AB - The adequate duration of antibiotic therapy in the treatment of bacterial infections is often unclear. For many indications guidelines recommend intervals with ranges of several days instead of fixed courses of treatment, and physicians tend to choose longer rather than shorter durations. The emergence of infections due to multidrug-resistant bacteria and the valuation of avoidable side effects from antibiotic agents raised the question whether a shortened duration of therapy is appropriate in specific indications. Therefore clinical trials to investigate the effectiveness of shorter in comparison to prolonged antibiotic treatment have yet been of growing interest to current research. Recent studies have shown that, concerning clinical endpoints, shorter duration of antibiotic therapy is not inferior to longer treatment in the management of pyelonephritis, intraabdominal infections, community acquired pneumonia an also gramnegative bloodstream infections and febrile neutropenia. PMID- 30286493 TI - [Do Vitamins Play a Role in the Pathogenesis and Therapy of Sepsis?] AB - Hospital mortality of severe sepsis and septic shock is still around 40 % according to recent studies. In accordance to the current sepsis definition, sepsis is a life-threatening organ dysfunction caused by a dysregulated response of the organism to infection. Septic shock is defined by vasopressor-dependent circulatory failure and lactic acidosis. Patients with sepsis and septic shock are often old and/or characterized by severe comorbidities, e. g. tumor or liver disease. These factors also predispose to malnutrition and hence to a corresponding deficiency of essential nutritional components e. g. vitamins. A number of recent studies and reviews have addressed the question whether deficiencies in certain vitamins may facilitate the transition from infection to septic shock. In addition, studies have investigated the effect of high-dose vitamin therapies on sepsis mortality and sepsis-associated organ dysfunctions. This article would like to summarize this current discussion with a focus on vitamin B1 (thiamine), vitamin C and vitamin D. PMID- 30286494 TI - [Update ESC-Guideline 2017: Focus on PAD]. AB - The updated ESC guidelines on PAD were developed, for the first time, as a collaboration between cardiologists and vascular surgeons and unveiled at the European Society of Cardiology (ESC) 2017 congress. Although awareness has improved, PAD is still associated with significant morbidity, mortality, and quality of life impairment. Primarily, the guidelines emphasize the need for a multidisciplinary management of these patients and propose "a vascular team". A new chapter on antithrombotic therapies is provided. In patients with symptomatic peripheral artery disease, clopidogrel can be considered over aspirin therapy (class IIb). Antiplatelet therapy is no longer recommended in asymptomatic peripheral artery disease patients (class III). After peripheral arterial intervention, dual antiplatelet therapy is recommended as a consensus. Moreover, all patients with lower extremity artery disease should be treated with statins to improve walking distance (class I) as well as supervised exercise therapy, even after revascularization. In claudicants, cardiovascular prevention and exercise training remain the cornerstones of management. The WIFI classification (risk stratification based on wound ischemia and foot infection) is proposed to primarily describe wound lesions. Regarding surgical or interventional therapies, the new guidelines propose an endovascular approach for short lesions (< 5 cm) in the aortoiliac or aortobifemoral region. Patients with infrapopliteal lesions should be treated with bypass surgery or endovascular therapy. Patients with coronary artery disease or heart failure should be considered for lower extremity peripheral artery disease screening (class IIb).

AB - UPDATE ON DIABETIC NEPHROPATHY 2018: The prevalance of elevated albuminuria in patients with diabetes is decreasing, while that of reduced eGFR is increasing, probably owing to more stringent blood pressure and blood glucose control.Well validated online score calculators for risk for renal replacement therapy, cardiovascular events and death are available online.Clinical variables remain more suited than histology for predicting end stage renal disease. Extracapillary hypercellularity, segmental sclerosis and exsudative lesions could represent a distinct risk phenotype.SGLT-2-inhibitors and GLP-1 analogues provide significant reductions of micro- and macrovascular end points. SGLT-2-inhibitors can only be prescribed at eGFR > 60 ml/min/1,73 m2, GLP-1 analogues and metformin at eGFR > 30 ml/min/1,73 m2.The ACC/AHA guideline 2017 defines arterial hypertension at blood pressure >= 130/80 mmHg, the ESC/ESH guideline 2018 at >= 140/90 mmHg. The blood pressure goal for patients with diabetes is < 130/80 mmHg, if well tolerated. ESC/ESH 2018 recommend not lowering blood pressure lower than 120/70 mmHg, in persons aged >= 65 years, systolic blood pressure 130 - < 140 mmHg is recommended. PMID- 30286496 TI - [Sleep Apnea]. AB - In 2017 the German Sleep Society (Deutsche Gesellschaft fur Schlafforschung und Schlafmedizin, DGSM) published the new S3 guideline "Nonrestorative Sleep/Sleep Disorders, chapter "Sleep-Related Breathing Disorders in Adults".Sleep apnea contributes to an increased morbidity and mortality in patients with cardiovascular diseases, e. g. coronary heart disease, heart failure and diabetes mellitus and is associated with an increased perioperative risk. It is also an important comorbidity in respiratory, neurologic and oncologic diseases. Treatment of sleep apnea can improve daytime sleepiness, quality of life und reduce blood pressure. In patients with atrial fibrillation, obstructive sleep apnea treatment should be optimized to improve treatment results. In addition to CPAP (continuous positive airway pressure) therapy and mandibular advancement devices, there are new therapies (e. g. hypoglossal nerve stimulation). Telemonitoring can help to improved therapy adherence. Nevertheless, in a current study CPAP could not prevent cardiovascular events in patients with moderate-to severe obstructive sleep apnea and established cardiovascular disease. Patients with predominantly central sleep apnea and systolic hear failure (left ventricular ejection fraction <= 45 %) had an increased cardiovascular mortality when treated with adaptive servoventilation. Therefore, ASV is contraindicated in this small group of patients. Further studies are ongoing. PMID- 30286497 TI - [Recent Developments in Myositis Syndromes]. AB - Idiopathic inflammatory myopathies (IIM) are a rare and clinically polymorphic and heterogenous group of myositis syndromes. Myositis is part of a systemic autoimmune disorder with various extramuscular manifestations affecting skin, lungs, joints, esophagus and other organ systems. Most myositis patients have autoantibodies against non organspecific antigens. More than 20 different autoantibodies are known. They are associated with different clinical phenotypes of adult or juvenile dermatomyositis or myositis-overlap syndromes and different genetic markers. Pure polymyositis, if not a monosymptomatic manifestation of a systemic disorder, so far has no marker antibody and is an exclusion diagnosis. Sporadic inclusion body myositis (sIBM) has no extramuscular manifestations, cN1A antibodies are directed against muscle-derived antigen and are not highly specific for IBM.Myositis syndromes differ in histopathology. Patients with anti synthetase-syndrome frequently have necrotizing perifascicular myositis with myonuclear actin inclusions.New classification criteria have been developed by the European (EULAR) and American (ACR) rheumatology societies and different outcome measurements for clinical studies are now available.There is still a lack of controlled therapeutic trials. However there is good consensus that glucocorticosteroids (GC) are necessary and effective to treat active myositis usually in combination with methotrexate or azathioprine. Rituximab is effective in GC-resistant myositis as well as high dose i. v. immune globulin (IVIG) in certain conditions. PMID- 30286498 TI - [Practical Genetic Testing in Gastroenterology]. AB - Genetic testing has become increasingly relevant in daily clinical practice due to the identification of susceptibility genes for several diseases. This article focuses on genetic testing for hereditary pancreatitis, inflammatory bowel disease and fatty liver disease. Several genetic variants that contribute to chronic pancreatitis development have been identified. If the individual aetiology of chronic pancreatitis is unclear, genetic testing for common predisposing variants should be offered. Inflammatory bowel diseases are complex and multifactorial disorders. However, rare mono- or oligogenic forms of disease exist and should be screened for, as personalized therapies can be offered to subsets of these patients. Genetic risk factors also promote the manifestation and progression of fatty liver disease, liver cirrhosis and hepatocellular carcinoma. In conclusion, genetic testing plays an increasing role in delineating the pathogenesis of gastroenterological and hepatic diseases, in the stratification of patients at risk for severe disease complications, and in the optimization of patient care.

PMID- 30286500 TI - [Papillary Fibroelastoma of the Pulmonary and Tricuspid Valve in Asymptomatic Patients]. AB - HISTORY: Case 1: admission to hospital of a 72-year-old male patient due to suspect tumor at the pulmonary valve. At admission the patient was hemodynamically stable with known coronary one vessel heart disease and arterial hypertension.Case 2: admission to hospital of a 74-year-old female patient due to symptoms of de novo angina pectoris with known coronary three vessel heart disease. FINDINGS AND DIAGNOSIS: In both patients suspect tumors could have been detected at the pulmonary- and tricuspid valve by transthoracic echocardiography. In case 1 coronary angiography showed a complex coronary three vessel heart disease with indication for surgery. In case 2 coronary angiography showed a subtotal stenosis of the RCA which could have been treated by percutaneous coronary intervention (PCI). THERAPY AND COURSE: In both cases the tumor were highly suspective to be benigne. Despite of the certain risk of embolism, surgery was only recommended in case 1 because the patient needed surgical revascularisation anyway due to the complex coronary three vessel heart disease. In case 2 the RCA stenosis has been treated by PCI and surgery has not been recommended. CONCLUSIONS: Echocardiography can help to detect cardiac tumors whereas the diagnosis can only be confirmed by biopsy. Further therapeutic procedures should be defined individually. PMID- 30286501 TI - Regular Physical Activity and Risk of Venous Thromboembolism. AB - Venous thromboembolism (VTE) is a complex multifactorial disease that represents a growing public health concern. Identification of modifiable risk factors at the population level may provide a measure to reduce the burden of VTE. In this review, we summarize current knowledge of the role of physical activity on the risk of VTE and VTE-related complications. We also discuss methodological challenges related to research on physical activity, and put forward plausible mechanisms for an association between physical activity and VTE. Up to now, published studies have reported diverging results on the relationship between physical activity and VTE, and a complex picture has emerged. However, the available evidence appears to be balanced toward a small beneficial effect of physical activity on the risk of incident VTE, but not in a dose-dependent manner. Still, the lack of an operational definition and standardized assessment method for physical activity, as well as several sources of bias, impairs the interpretation of the available literature. Additional work is necessary to understand the role and how to apply physical activity in the VTE setting. Future research should utilize objective assessment strategies of physical activity and physical fitness, account for the fluctuating nature in habitual activity levels, and explore the role of physical activity in the areas of secondary prevention and VTE-related complications. PMID- 30286502 TI - Impact of Exercise/Sport on Well-being in Congenital Bleeding Disorders. AB - Physical activity provides many benefits in patients with congenital bleeding disorders. Patients with hemophilia are encouraged to participate in exercise and sports, especially those patients receiving prophylaxis. Several publications and guidelines have explored this issue in hemophilia patients, evaluating in particular the impact of physical activity on patients' well-being and quality of life. The other rare congenital bleeding disorders are less studied; they are heterogeneous in terms of clinical bleeding phenotype, incidence of hemarthrosis, and arthropathy. Furthermore, prophylaxis in these patients is less common than in hemophilia patients, which must be considered when choosing the type of physical and sporting activity. In this review, the authors have analyzed the literature focusing their attention on those rare coagulation disorders that may be complicated by arthropathy and the role of exercise and sports in this context. PMID- 30286503 TI - Acquired and Genetic Thrombotic Risk Factors in the Athlete. AB - While athletes are often considered the epitome of health due to their physique and lowered potential for metabolic and cardiovascular diseases, they may also be at risk for the onset and development of venous thromboembolism (VTE). In an attempt to achieve and remain competitive, athletes are frequently exposed to numerous athlete-specific risk factors, which may predispose them to VTE through the disruption of factors associated with Virchow's triad (i.e., hypercoagulability, venous stasis, and vessel wall injury). Indeed, hypercoagulability within an athletic population has been well documented to occur due to a combination of multiple factors including exercise, dehydration, and polycythemia. Furthermore, venous stasis within an athletic population may occur as a direct result of prolonged periods of immobilization experienced when undertaking long-distance travels for training and competition, recovery from injury, and overdevelopment of musculature. While all components of Virchow's triad are disrupted, injury to the vessel wall has emerged as the most important factor contributing to thrombosis formation within an athletic population, due to its ability to influence multiple hemostatic mechanisms. Vessel wall injury within an athletic population is often related to repetitive microtrauma to the venous and arterial walls as a direct result of sport-dependent trauma, in addition to high metabolic rates and repetitive blood monitoring. Although disturbances to Virchow's triad may not be detrimental to most individuals, approximately 1 in 1,000 athletes will experience a potentially fatal post exercise thrombotic incidence. When acquired factors are considered in conjunction with genetic predispositions to hypercoagulability present in some athletes, an overall increased risk for VTE is present. PMID- 30286504 TI - [Risks and Side Effects of Psychotherapy]. PMID- 30286505 TI - [Definition and Decision-Making in the Determination and Detection of Side Effects of Psychotherapy]. AB - There is no generally accepted definition of side effects, which causes problems in research and clinical practice. Not even the distinction between main and side effects is always clear. Several judgments are needed in the assessment of side effects. First, it must be decided where to look for unwanted events. Events are defined by the temporal contingency with the treatment. Second, it must be made a judgement whether it is an unwanted or wanted event. Everything is unwanted, which would be problematic, if it would be possible to do without it. Thirdly, a causal relationship with the treatment must be made plausible. Fourthly, a decision must be made that the treatment has been adequate and not malpractice or other unethical behavior. Side effects can be defined as unwanted consequences of correct treatment. The relevance of side effects is depending on severity and duration. PMID- 30286506 TI - [CBASP as an Inpatient Concept for Treatment-Resistant Chronic Depression: A Pilot Study of the Relationship between Adverse Effects and Treatment Outcome]. AB - BACKGROUND: Inpatient psychotherapy might trigger adverse effects among others due to short but intensive treatment. Thus, in this pilot study, certain adverse effects of the multidisciplinary inpatient Cognitive Behavioral Analysis System of Psychotherapy (CBASP) for treatment-resistant chronically depressed patients as well as their relationship to treatment outcome (response-, remission-, and relapse-rates) are examined. MATERIAL AND METHODS: 50 patients with treatment resistant and chronic depression completed the structured 12-weeks inpatient treatment program. Adverse effects were assessed by 1) deterioration of depressive symptoms (measured by the Hamilton Depression Rating Scale, HDRS) at discharge and 2) a self-report questionnaire measuring Adverse Effects of Inpatient Psychotherapy (ADEFIP), which were filled out 6 to 12 months after discharge by the patients. RESULTS: After 12 weeks of treatment, 84% could be classified as responder, of whom 44% fulfilled the remission criterion. 16% were Non-Responder. According to HDRS, none of the patients showed objective deterioration of the depressive symptoms. Six months after discharge, 40% of the responders suffered from relapse. Concerning the ADEFIP, 66% of the patients reported transient deterioration of symptoms. These patients were less likely to achieve remission. Over 50% reported interpersonal conflicts with treatment team members or other patients without any relation to outcome. Finally, more than half of the patients reported significant changes in social relationships after discharge. These patients were less likely to relapse. Overall, 94% of the patients reported at least one of the in this study assessed adverse effects. CONCLUSIONS: Despite some limitations, this pilot study suggests that the CBASP inpatient program could indeed cause adverse effects. However, only subjective transient deterioration appeared to have a negative impact on the individual treatment outcome in the short-term. Results encourage further research concerning adverse treatment effects in the context of short- and long-term treatment outcome investigating how relevant adverse effects are. PMID- 30286507 TI - [Negative Indicators in the Psychotherapeutic Process: Frequency and Relationship with Attachment Characteristics and Treatment Outcome among Patients with Social Anxiety Disorder]. AB - Within the SOPHO-Net-Project, mainly focusing on a randomized-controlled trial comparing short term cognitive and psychodynamic psychotherapy for social anxiety disorder, a subsample consisting of 88 patients from 3 of the 5 study sites was investigated to examine the relationship between outcome, initial attachment characteristics and negative indicators during the process. These negative indicators were assessed with the Vanderbilt Negative Indicators Scale which was applied to an early (3rd), a middle (9th) as well as a late therapy (22nd) session. The study shows that negative indicators as a whole were relatively rare with a higher frequency within the psychodynamic therapies for which a relationship between negative indicators and outcome could be found. Contrary to expectation, initial attachment characteristics were not related to negative indicators. PMID- 30286508 TI - [Complains about Psychotherapy and their Impact on Patients]. AB - Unprofessional psychotherapy damages its otherwise good standing. For that reason, a public discussion about malpractice and unethical psychotherapist behavior is oftentimes missing even though addressing the topic openly could illustrate its rarity and promote a professional handling of psychotherapeutic misconduct. In the presented study, qualitative content analysis was conducted to analyze malpractice claims that were sent to the Psychotherapeutic Chamber of North Rhine-Westphalia (Germany) in 2011 and 2012. All letters were anonymized and the processing of the claims was completed. In total, 149 relevant malpractice claims and 124 statements about consequences of malpractice behaviors were identified. Most malpractice claims were related to the category "violation of therapeutic basic variables" (40.3%), followed by "violation of general conditions" (16.8%) and "financial abuse" (12.1%). In consequence, 28.2% of the patients described a "deterioration of their symptoms". These results shed light on the variation of existing malpractice claims and their consequences for patients indicating the need for awareness-raising actions for therapists and patients.

AB - This report describes the development of a questionnaire aiming in assessing unwanted effects of group psychotherapy and side effects of the group setting. Based upon interviews with experts and considering a model differentiating group related, therapist related strain within groups, stress caused by other members and subjective excessive demands, a first version of the questionnaire was developed and tested in the clinical field using heterogeneous groups. The data set from this sample (N=168 patients) was used to construct a 24-item short version with 6 items per scale reflecting the 4 contents. A first comparison of different groups related to unwanted experiences and side effects indicates that the NUGE-questionnaire might be useful in differentially assessing these effects. This should now be tested in more systematic studies.

AB - A new homogeneous bromine(-I/I) redox catalysis is described, which is based on monomeric bromine(I) compounds containing transferable phthalimidato groups. These catalysts enable intermolecular C-H amination reactions at previously unaccessible aliphatic positions and thus enlarge the synthetic potential of direct C-N bond formation, including its application in the synthesis of alkaloid building blocks. This aspect is demonstrated by a new synthetic approach to aspidospermidine. In addition to the development of the catalyst system, the structures of the involved bromine(I) key catalysts were fully elucidated, including by X-ray analyses. PMID- 30286511 TI - Anthocyanidines structural study using positive electrospray ionization triple quadrupole mass spectrometry and H/D exchange. AB - We report herein a detailed structural study by collision-induced dissociation (CID) of non-glycosylated anthocyanins (anthocyanidines) using electrospray ionization triple quadrupole mass spectrometry (ESI-QqQ) and isotope labeling experiments to understand the fragmentation process often used in mass spectrometry analysis of this class of compounds. Tandem mass spectrometric product ion spectra for three anthocyanidines (cyanidin, delphynidin, and pelargonin) were evaluated to propose fragmentation mechanisms to this natural colorant class of organic compounds. The proposed rearrangements, retro Diels Alder reaction, water loss, CO losses, and stable acylium ion formation, were evaluated based on tandem mass spectrometric experiments of normal and labeled precursor ions together to computational thermochemistry. B3LYP/6-311+G** ab initio calculations studies were carried out to obtain energy diagrams to show the viability of the proposed mechanisms. The CO losses fragmentation channels have lower energies when compared to water losses, and the other proposed fragmentations. The isotope labeling experiments indicate the H/D exchange of the hydroxyl protons and corroborate the proposed general fragmentation mechanism for anthocyanidins. PMID- 30286512 TI - Validation of Quantitative Microbial Risk Assessment Using Epidemiological Data from Outbreaks of Waterborne Gastrointestinal Disease. AB - The assumptions underlying quantitative microbial risk assessment (QMRA) are simple and biologically plausible, but QMRA predictions have never been validated for many pathogens. The objective of this study was to validate QMRA predictions against epidemiological measurements from outbreaks of waterborne gastrointestinal disease. I screened 2,000 papers and identified 12 outbreaks with the necessary data: disease rates measured using epidemiological methods and pathogen concentrations measured in the source water. Eight of the 12 outbreaks were caused by Cryptosporidium, three by Giardia, and one by norovirus. Disease rates varied from 5.5 * 10-6 to 1.1 * 10-2 cases/person-day, and reported pathogen concentrations varied from 1.2 * 10-4 to 8.6 * 102 per liter. I used these concentrations with single-hit dose-response models for all three pathogens to conduct QMRA, producing both point and interval predictions of disease rates for each outbreak. Comparison of QMRA predictions to epidemiological measurements showed good agreement; interval predictions contained measured disease rates for 9 of 12 outbreaks, with point predictions off by factors of 1.0-120 (median = 4.8). Furthermore, 11 outbreaks occurred at mean doses of less than 1 pathogen per exposure. Measured disease rates for these outbreaks were clearly consistent with a single-hit model, and not with a "two-hit" threshold model. These results demonstrate the validity of QMRA for predicting disease rates due to Cryptosporidium and Giardia.

AB - With limited knowledge on epidemiological and morphological characteristics of sudden unexplained nocturnal death syndrome (SUNDS), this study was aimed to identify such data in Thai SUNDS autopsy cases. All the cases were men and nondrug abusers aged 20-49 years old. Most cases were originated in the Northeastern region of Thailand. Half of them were found dead from midnight to 6 a.m., with a peak time at 2 a.m. The death rate was relatively higher in May and June. Most SUNDS cases were blue-collar workers (93.2%) and nonsmokers (60%), with a normal BMI (72.1%). Approximately one-fifth of the cases had detectable blood alcohol concentrations. Symptoms before death were respiratory difficulty, seizures, and urinary incontinence. Their mean heart weight was 329.8 +/- 35.1 g. Their lungs (88.6%) had some degree of congestion. Acute pancreatitis was not found in these SUNDS cases, and approximately half (40.9%) of the cases had their gastric content <100 mL.

AB - OBJECTIVE: Analysis of the relationship between the body self (BS) and the sense of coherence (SOC) in women after breast surgery due to cancer in comparison with a control group. METHODS: A cross-sectional study in a group of 78 women using the body-self questionnaire (BS-Q), and the life orientation questionnaire (SOC 29). Statistics based on the IBM SPSS v.25. RESULTS: Multivariate analysis of variance (MANOVA) has shown significant differences based on groups in experiencing intimacy, manifesting femininity, body acceptance, and manageability. In particular, manifesting femininity and body acceptance showed a big effect size (0.30 < partial n2 < 0.32). Correlation analysis between the BS Q and SOC-29 subscales and Fisher's r to z transformation determines that the differences between groups were significant in favour of healthy women in two sets of variables: experiencing intimacy/meaningfulness and attitude to food and weight/manageability. CONCLUSIONS: Breast cancer survivors are at greater risk of developing decreased body acceptance and problems in intimacy, and have less correlation than the healthy control group between manageability and meaningfulness with an appropriate attitude to food and intimate relationship with their partner, respectively. A higher manifestation of femininity in the treated group can be considered a positive but socioculturally conditioned coping strategy.

AB - For patients with incurable neurodegenerative disorders such as Huntington's (HD) and Parkinson's disease, cell transplantation has been explored as a potential treatment option. Here, we present the first clinicopathological study of a patient with HD in receipt of cell-suspension striatal allografts who took part in the NEST-UK multicenter clinical transplantation trial. Using various immunohistochemical techniques, we found a discrepancy in the survival of grafted projection neurons with respect to grafted interneurons as well as major ongoing inflammatory and immune responses to the grafted tissue with evidence of mutant huntingtin aggregates within the transplant area. Our results indicate that grafts can survive more than a decade post-transplantation, but show compromised survival with inflammation and mutant protein being observed within the transplant site.

AB - OBJECTIVES: This study aimed to predict the displacement of self-expanding transcatheter heart valves (THV) during final deployment. BACKGROUND: Accurate device positioning during transcatheter aortic valve implantation (TAVI) is crucial for optimal results. METHODS: At our institution, 103 patients who underwent transfemoral TAVI with Evolut R were retrospectively identified. Multiple linear regression models were created, and a predictor equation was built to quantify the factors that may affect THV behavior. RESULTS: Multiple linear regression analysis for THV displacement on the left coronary cusp (LCC) identified the angle between the THV and the ascending aorta (ATA), predilation, and less operator experience as independent predictors of upward displacement, whereas estimated glomerular filtration rate (eGFR) was inversely related with THV behavior (95% confidence interval: 0.219 to 0.340, 0.447 to 2.092, 0.165 to 1.757, and -0.053 to -0.011, respectively). Predictors of THV displacement on the noncoronary cusp side could not be identified using this model. CONCLUSIONS: The ATA at the point of recapture, predilation, and less operator experience were independent predictors of upward displacement of THV on the LCC side. eGFR was an independent predictor of THV downward displacement on the LCC side. Of them, the ATA was the strongest predictor. Physicians may need to adjust this angle adequately before deployment to achieve the appropriate position.

Herein, a [11 C] CO dispending system for performing multiple reactions with a single batch of cyclotron-produced [11 C]CO2 is described. This semiautomated setup allows for more rapid and efficient screening of reactions and reaction conditions compared with the traditional "one beam for one reaction" strategy.

AB - This article describes how risk has been conceptualized in the business and organizational literature through four distinct transformations: from the techno scientific perspective to the cognitive, the social-cultural, and, finally, to the constructionist perspective. Each domain conceptualizes risk in different ways, as organizations have found it difficult to understand and mitigate using the risk management tools available. Conceptualizing risk as sensemaking becomes relevant due to the complexity of information available to the risk manager, and, coupled with time constraints, this means that risk managers increasingly rely on making sense of possible threats rather than on the accuracy of the information received. This shift presents four contributions to the current literature. First, it suggests that the role of risk management is shifting from being technical in nature to being about risk sensemaking, where the manager engages with the social and physical environment with the aim of acquiring cues that could indicate how future events will unfold. Second, a sensemaking perspective implies a shift in the use of risk management systems from being "containers" of knowledge about past risk events to lending legitimacy to the plausibility of the success of future decisions. Third, the role of the risk manager in managing individual risks changes and becomes one of managing everything using the social networks and systems available as indicators of future risk events. Finally, the risk manager and the systems he or she relies upon are regarded as a source of risk in themselves as both act as gatekeepers for organizational risk decision making.

AB - Fractional flow reserve derived by coronary computed tomography angiography (CTA; FFRCT) is an accurate noninvasive method for identifying coronary artery disease (CAD) and detecting hemodynamically significant stenosis. Although initially proposed as noninvasive tools to "rule out" significant CAD in low-risk patients, CTA and FFRCT are now utilized in higher-risk patients. Furthermore, new applications of CTA and FFRCT include a planning tool for percutaneous coronary intervention (PCI), which allows the cardiologist to assess lesion-specific ischemia, plan stent locations and sizes, and use virtual remodeling of the lumen (virtual stenting) to assess the functional impact of PCI. The purpose of this review is to discuss the principles of CTA and FFRCT acquisition, and their application for PCI planning, even before invasive angiography is performed. PMID- 30286520 TI - Three-year clinical outcomes of patients treated with everolimus-eluting bioresorbable vascular scaffolds: Final results of the ABSORB EXTEND trial. AB - BACKGROUND: There is still limited data on the very long term clinical outcomes after ABSORB BRS in daily practice. We sought to evaluate the 3 year-performance of the Absorb bioresorbable vascular scaffolds for the treatment of low/moderate complexity patients enrolled in the ABSORB EXTEND trial. METHODS: ABSORB EXTEND is a prospective, single-arm, open-label clinical study in which 812 patients were enrolled at 56 sites. This study allowed the treatment of lesions <=28 mm in length and reference vessel diameter of 2.0-3.8 mm (as assessed by on-line QCA). To determine the independent predictors of MACE, a multivariable logistic regression model was built using a stepwise (forward/backward) procedure. RESULTS: Average population age was 61 years and 26.5% had diabetes. Most patients had single target lesion (92.4%). Adequate scaffold deployment (PSP) was achieved in 14.2% of the cases. At three years, the composite endpoints of MACE and ischemia-driven target vessel failure were 9.2% and 10.6%, respectively. The cumulative rate of ARC definite/probable thrombosis was 2.2%, with 1.2% of the cases occurring after the 1st year. Independent predictors of MACE were hypertension and the need for "bail out" stent. CONCLUSION: At three-year follow up, the use of ABSORB in low/moderate complex PCI was associated with low and acceptable rates of major adverse clinical events, despite the infrequent use of the recommended contemporary scaffold deployment technique. However, scaffold thrombosis rate was higher than reported with current generation of metallic DES. The study is registered on clinicaltrials.gov (unique identifier NCT01023789). PMID- 30286521 TI - Predictive Value of Quantitative Uterine Fibroid Perfusion Parameters From Contrast-Enhanced Ultrasound for the Therapeutic Effect of High-Intensity Focused Ultrasound Ablation. AB - OBJECTIVES: To assess the predictive significance of quantitative perfusion parameters from contrast-enhanced ultrasound (CEUS) for the therapeutic response to high-intensity focused ultrasound (HIFU) ablation in patients with uterine fibroids. METHODS: A total of 263 patients with single uterine fibroids were treated with HIFU ablation under ultrasound guidance. The arrival time, peak time, enhancement time, enhancement intensity, and enhancement rate were evaluated with pretreatment CEUS. According to a nonperfused volume ratio evaluation by posttreatment magnetic resonance imaging, all patients were assigned to groups with volume ratios of 70% or higher and lower than 70%. Then the predictive performances of different parameters for ablation efficacy were studied. RESULTS: The arrival time, peak time, and enhancement time in the group with a nonperfused volume ratio of 70% or higher were longer than those in the group with a volume ratio lower than 70% (mean +/- SD, 16.7 +/- 3.5, 26.5 +/- 4.9, and 10.2 +/- 2.6 seconds, respectively, versus 13.3 +/- 4.2, 20.8 +/- 5.4, and 7.6 +/- 2.3 seconds), whereas patients with a volume ratio of 70% or higher had a lower mean enhancement intensity and enhancement rate than those with a volume ratio lower than 70% (29.7 +/- 16.7 dB and 3.2 +/- 1.5 dB/s versus 63.2 +/ 26.3 dB and 8.6 +/- 4.3 dB/s; P < .05). The nonperfused volume ratio was negatively correlated with the enhancement intensity and enhancement rate (r = 0.631 and -0.712) but positively correlated with the arrival time, peak time, and enhancement time (r = 0.322, 0.456, and 0.477; P < .05). The areas under the receiver operating characteristic curve for the enhancement time, enhancement intensity, and enhancement rate were 0.73, 0.79, and 0.81 (P < .05). CONCLUSIONS: Quantitative parameters from CEUS are potentially useful for evaluating the therapeutic effect of HIFU ablation for uterine fibroids. PMID- 30286522 TI - Distress predicts utilization of psychosocial health services in oncology patients. AB - OBJECTIVE: The prevalence of increased distress among cancer patients has been well established and is known to be associated with negative consequences. Limited research has examined the association between distress and utilization of services, however, which is critical to understanding whether measurements of distress are being used to optimize patient care in the context of cancer. METHODS: One thousand two hundred thirteen adult cancer patients completed the Distress Thermometer and Patient Needs Assessment early in their cancer care. Electronic medical record (EMR)-abstracted data included psychosocial service utilization in the 12 months following the completion of these psychosocial metrics. Logistic regressions followed by t tests were completed to assess if distress or unmet needs were affiliated with service utilization rates. RESULTS: When controlling for age, distress significantly predicted service utilization rates overall. Follow-up t tests suggest that use of social work and registered dietician services was higher among those with distress scores greater than 6. When assessing unmet needs, utilization rates were positively associated with number of unmet needs, specifically for social work and dieticians. CONCLUSIONS: Distress and unmet needs were related to higher rates of psychosocial service utilization during the 12 months following assessment of symptoms. These results support the continued mandate for evaluation of distress and suggest that psychosocial screening may be assisting in directing referrals and enhancing comprehensive care for patients. As psychosocial services grow, the need for continued evaluation is recommended to determine if psychology and chaplaincy services are utilized at higher rates as available providers increase. PMID- 30286523 TI - Using micro computed tomography to investigate a fetal mummy with possible situs inversus: A case report. AB - OBJECTIVES: Computed tomography (CT) is commonly used to noninvasively examine mummified remains, but can have resolution limitations when analyzing smaller mummified specimens, such as fetal mummies. This short report determines if the enhanced resolution of micro CT improves the anatomical analysis of mummified fetal anatomy. METHODS: A fetal mummy from an anatomical collection was scanned by a micro CT at a resolution of 0.08 mm slice thickness. The mummy was also scanned at a resolution of 0.6 mm slice thickness to mimic the approximate minimum resolution of a conventional CT scanner. The anatomy was virtually reconstructed at both resolutions to compare anatomical detail for determining sex, gestation, and the presence of congenital/ pathological conditions. RESULTS: The anatomical reconstructions based on the micro CT were significantly more detailed than the conventional CT data. This resulted in improved identification of sex and the presence of a congenital/ pathological condition. CONCLUSION: Micro CT should be considered when examining fetal mummies, because of the enhanced resolution resulting in improve anatomical analysis. PMID- 30286524 TI - Global country-level estimates of associations between adult height and the distribution of income. AB - OBJECTIVES: This article presents the first estimates of global associations between adult height and the distribution of income, and considers the roles of regional heterogeneity, heterogeneity across low- and high-income countries, and of infant mortality as a potential mediator. METHODS: Linear parametric and semiparametric regressions predicting mean height and sexual dimorphism in height are estimated using data on one cohort born in 1996 with height measured in 2016. Measurement error in income inequality is addressed using an instrumental variables method. RESULTS: Across countries higher income per capita is strongly associated with higher mean height, and higher income inequality is associated with lower mean height after holding mean income constant. These relationships vary with mean income: at low incomes, higher mean income strongly predicts greater height but income inequality has no statistically significant effect, whereas for high-income countries, only higher income inequality predicts lower height, and only in Europe. Sexual dimorphism in height is positively associated with mean income at low incomes, but it is not related to income inequality. CONCLUSIONS: Controlling for income inequality has modest effects on a positive height-income gradient. Greater inequality predicts lower height after holding income per capita constant, suggesting that mean height should be used with caution as a proxy for standard of living in some contexts. The extent to which these associations reflect causality running from economic conditions to height cannot be determined from these results. PMID- 30286525 TI - A sentinel in Mitraclip intervention: Catch the enemy! AB - Cerebral ischemic lesions occurring during transcatheter valve interventions are common feared complications and the use of filter device seems to reduce their incidence. We report the case of an 84-year old female patient with severe mitral regurgitation undergoing MitraClip. During the trans-esophageal echocardiography (TEE)-guided procedure was detected the presence of a little fibrin strand adherent to the steerable guide catheter for which we decided to implant the Claret CE Pro (Claret Medical, Inc. Santa Rosa, CA, USA) cerebral protection device and to continue the procedure during which the thrombus disappeared. At the end of the procedure a big thrombus was detected in the distal filter. The histologic analysis of the debris captured by the filters showed the presence of a thrombus, compatible with the image identified by TEE. PMID- 30286526 TI - Reaping the Benefits and Avoiding the Risks: Unrealistic Optimism in the Health Domain. AB - People's perceptions of benefits and risks play a key role in their acceptance or rejection of medical interventions, yet these perceptions may be poorly calibrated. This online study with N = 373 adults aged 19-76 years focused on unrealistic optimism in the health domain. Participants indicated how likely they were to experience benefits and risks associated with medical conditions and completed objective and subjective numeracy scales. Participants exhibited optimistic views about the likelihood of experiencing the benefits and the side effects of treatment options described in the scenarios. Objective and subjective numeracy were not associated with more accurate ratings. Moreover, participants' underestimation of the risks was significantly greater than their overestimation of the benefits. From an applied perspective, these results suggest that clinicians may need to ensure that patients do not underestimate risks of medical interventions, and that they convey realistic expectations about the benefits that can be obtained with certain procedures. PMID- 30286527 TI - Transradial left gastric artery embolization to treat severe obesity: A pilot study. AB - BACKGROUND: Bariatric surgery is currently the only effective treatment with long lasting results to treat severe obesity. OBJECTIVES: We performed a pilot study to evaluate the feasibility, safety and efficacy of percutaneous distal embolization of the left gastric artery (LGA) using a transradial approach. METHODS AND RESULTS: We recruited seven severely obese male patients (mean age 48 +/- 7 years) referred for diagnostic coronary angiography. Mean baseline weight was 160 +/- 27 kg and body mass index was of 52 +/- 8 kg/m2 . We successfully injected 300-500 MUm polyvinyl alcohol particles using 5Fr catheters and all distal LGA were occluded at the end of procedures. Mean procedure duration was 24 +/- 13 min and mean fluoroscopy time was 10 +/- 5 min. Six patients reported mild transient epigastric discomfort, which resolved with proton pump inhibitors. At 2 months, the average weight loss was of 7 +/- 6 kg (median loss: -10 kg [-2, 11]), 6 +/- 12 kg (median loss: -9 kg [-16, +4]) at 6 months and 13 +/- 17 kg (median loss: -11 kg [0, -25]) up to 12 months after index procedures. CONCLUSION: Percutaneous transradial LGA embolization appears to be a promising technique to reduce the obesity burden. Randomized trials are required to further delineate the risk/benefit ratio, potential clinical indications and long term results. PMID- 30286528 TI - Analyzing Disaster Loss Trends: A Comparison of Normalization Methodologies in South Korea. AB - Increasing concern for climate change adaptation and disaster risk reduction is driving the need for more accurate and sophisticated tools of analysis to protect populations. Standards of analysis that can normalize measurements under various contexts are particularly valuable in the global arena of disaster management. One concern that may benefit from normalizing is the analysis of disaster loss trends. Previous studies have used a combination of inflation, wealth, and societal factors in their normalization of disaster loss methodologies. This study examines the various normalization methods in previous research and applies a selection of eight formulae to 50 years of disaster data in South Korea. The results show both decreasing and increasing trends in disaster damage losses based on the methods, but there are curious biases under the results that may be artifacts of Korea's unique experiences in economic development. The conclusion discusses how the case of Korea may help to clarify the optimal normalization methodology for other countries. PMID- 30286529 TI - Distinctive distributions and migrations of 239+240Pu and 241Am in Chinese forest, grassland and desert soils. AB - The vertical distributions and downward migrations of the global fallout derived 239+240Pu and 241Am in diverse types of Chinese soils (forest, grassland and desert) were studied. The mean 239+240Pu and 241Am activity concentrations in the investigated soil cores were 0.28-0.69 mBq/g and 0.13-0.37 mBq/g, respectively, while the accumulative inventories were 61.53-138.99 Bq/m2 for 239+240Pu and 28.29-61.05 Bq/m2 for 241Am. The convection-dispersion equation (CDE) was used to calculate the migration parameters of 239+240Pu and higher apparent dispersion coefficients (D) were observed for the acidic forest soils compared with the alkaline grassland and desert soils; meanwhile a compartment model was employed to compare the migration of 239+240Pu and 241Am in successive soil layers which showed that the migration behaviors of 239+240Pu and 241Am were rather similar; both velocities were less than 0.3 cm/y in diverse types of soils and these findings were compatible with those of short-term laboratory simulation experiments in China. PMID- 30286530 TI - The characteristics of carbonaceous aerosol in Beijing during a season of transition. AB - Carbonaceous aerosol was measured during fall of 2010 in Beijing. Daily variation of organic carbon (OC) was found to coincide with that of relative humidity (RH), and the OC to elemental carbon (EC) ratios were more than doubled during the more humid periods (RH above 0.75) compared to other conditions. This large increase in OC/EC could not be explained by the variations of primary biomass burning emissions but was accompanied by a five-fold increase in the sulfate to EC ratio. It was then inferred that secondary organic aerosol (SOA) formation was enhanced under the more humid conditions, presumably through aqueous-phase processes. This enhanced SOA formation might be partially associated with particles externally mixed with black carbon, as indicated by the RH-dependent relationships between aerosol optical attenuation and EC loading. In addition, organic aerosols exhibited different properties between the more humid and the other periods, such that they were less volatile and charred more significantly during thermal optical analysis in the former case. These differences coincided with the evidence of enhanced SOA formation under the more humid conditions. This study highlights the necessity of incorporating aqueous-phase chemistry into air quality models for SOA. PMID- 30286531 TI - Immobilization and characterization of Fe(0) catalyst on NaOH-treated coal fly ash for catalytic reduction of p-nitrophenol. AB - In this study, coal fly ash (CFA), i.e., an industrial waste product created in large quantities by thermoelectric power plants, was treated with sodium hydroxide to afford a novel Fe (0) catalyst supported on alkaline-treated CFA. The NaOH-treated CFA (NCFA) exhibited a morphological change from slick spheres to pointed, leaf-like spheres, which was accompanied by a noticeable increase in specific surface area from 1.2 to 7.5 m2/g. Sequential addition of an Fe(III) precursor and NaBH4 solution to a suspension of NCFA resulted in the formation of Fe (0) particles on the surface of NCFA (Fe/NCFA). The catalytic activity of Fe/NCFA toward the reduction of p-nitrophenol (p-NP) was examined; among the Fe/NCFAs synthesized from different NCFAs (1, 3, and 7 M NaOH), the Fe/3 M NCFA sample displayed the highest activity owing to the highest Fe content on its surface, without leaching any toxic heavy metals. In addition, the effects of NaBH4 concentration, Fe loading, and catalyst dosage on the catalytic reduction of p-NP by Fe/NCFA were comprehensively investigated. Finally, the recyclability and stability of Fe/NCFA were examined, demonstrating the complete reduction of p NP over four continuous recycling cycles. The present results demonstrate the marked potential of CFA as a component in reactive catalysts for the removal of environmental pollutants from wastewater. PMID- 30286532 TI - Recovery of phosphorus and nitrogen from human urine by struvite precipitation, air stripping and acid scrubbing: A pilot study. AB - Sustainable and closed-loop nutrient cycling require the recovery of valuable resources from wastewater. Resource recovery from diluted wastewater streams is limited by diluted concentrations and unfavorable reaction kinetics. In comparison, source separated urine allows resource recovery from a highly concentrated nutrient stream, resulting in a more sustainable and efficient recovery practice. Different nutrient recovery methods from urine have been studied in lab-scale, but pilot or full-scale process evaluations remain sparse. In this study, recovery of struvite and ammonium sulfate from urine of pregnant women was demonstrated at a pilot-scale treatment facility by means of precipitation and air stripping/acid scrubbing. The system achieved 94% struvite precipitation efficiency but merely 55% of the crystals were removed and recovered. The low phosphorus recovery was due to the washout of small crystals that escaped the sieve and settling tank, hence requiring an improved method for crystals capture. The removal and recovery efficiencies for nitrogen were 93% and 85%, respectively. Composition analysis of the produced fertilizers indicated that struvite was the dominated precipitate and quality of the ammonium sulfate met European standards. Carbamazepine and diclofenac were added in the urine to measure the fate of pharmaceuticals in the treatment system. Very little of the spiked pharmaceuticals (<0.01%) accumulated in the produced struvite and ammonium sulfate. The overall energy demand of the pilot system was 1066 MJ per m3 urine processed or 198 MJ per kg N removed. Energy efficiency was not optimized and can be improved in many ways. PMID- 30286533 TI - Facile one-pot synthesis of a porphyrin-based hydrophilic porous organic polymer and application as recyclable absorbent for selective separation of methylene blue. AB - With the development of dye production and printing industry, dyes wastewater has increased dramatically. The resulting environmental pollution problem is increasing seriously. In the present work, a porphyrin-based porous organic polymer (PPOPs-OH) was synthesized by using pyrrole and 2,6-dihydroxynaphthalene 1,5-dicarbaldehyde (DHNDA) as basic building block in situ. This method was cost- and time-efficient, without the participation of metal catalysts. Further reaction of PPOPs-OH with chlorosulfonic acid, a new sulfonic acid functional material (PPOPs-SO3H) was obtained with the increasing electronegativity and hydrophilicity. PPOPs-SO3H exhibit good adsorption capacity for methylene blue (MB) from water (980.4 mg g-1) and excellent selectivity for MB in the present of rhodamine B (RhB) and methyl orange (MO). Mechanism investigation revealed that electrostatic in comparison with pi-pi interaction is the prominent force in the absorption process. Recycling experiments found the absorption properties of PPOPs-SO3H did not reduce significantly after several cycles. As a consequence, our findings highlight an appealing opportunities for covalent organic polymers with their potential application as high-efficiency and robust adsorbents for pollutants removal and environmental protection. PMID- 30286534 TI - Mass spectrometric identification of in vitro-generated metabolites of two emerging organophosphate flame retardants: V6 and BDP. AB - The aim of the present study was to investigate the in vitro metabolism of two emerging organophosphate flame retardants, namely tetrekis(2 chlorethyl)dichloroisopentyldiphosphate (V6) and bisphenol-A bis-diphenyl phosphate (BDP) in human liver microsomes (HLMs), HLM S9 fractions and in human serum. In particular, the role of cytochrome P450 (CYPs) enzymes and/or paraoxonases (PONs) in the formation of V6 and BDP phase I metabolites was studied. Mono-, di-hydroxylated and hydrolytic phase I metabolites of V6 were mainly formed by CYPs in HLMs, while hydrolytic and O-dealkylated phase I metabolites of BDP were generated by PONs mainly in serum experiments. Limited number of glucuronidated and sulfated phase II metabolites were also identified for the two chemicals. The activity of seven recombinant CYPs (rCYPs) including rCYP1A2, rCYP2B6, rCYP2C9, rCYP2C19, rCYP2D6, rCYP2E1 and rCYP3A4 in the in vitro phase I metabolism of V6 and BDP was investigated. The formation of V6 metabolites was catalyzed by several enzymes, especially rCYP1A2 that was responsible for the exclusive formation of two metabolites, one primary (M1) and its secondary metabolite (M9). For BDP, only one phase I metabolite (MM1) was catalyzed by the seven rCYPs. Collectively, these results indicate that CYPs have a predominant role in the metabolism of V6, while PONs have a predominant role in BDP in vitro metabolism. These results are a starting point for future studies involving the study of the toxicity, bioaccumulation and in vivo biomonitoring of V6 and BDP. PMID- 30286535 TI - DnBP-induced thyroid disrupting activities in GH3 cells via integrin alphavbeta3 and ERK1/2 activation. AB - Di-n-butylphthalate (DnBP) exhibits alarming thyroid disrupting activities. However, the toxic mechanism of DnBP is not completely understood. In this study, we investigated the mechanism of DnBP in thyroid disruption. Rat pituitary tumor cell lines (GH3) were treated with DnBP in different scenarios, and cell viabilities, target gene transcriptions and protein levels were measured accordingly. The results showed that after treatment with DnBP (20 MUmol/L), cell proliferation increased to 114.69% (p < 0.01) and c-fos gene was up-regulated by 1.57-fold (p < 0.01). Both nuclear thyroid hormone receptor beta (TRbeta) and membrane TR (integrin alphav and integrin beta3) genes were up-regulated by 1.31 , 1.08- and 2.39-fold (p < 0.01), respectively, the latter was inhibited by Arg Gly-Asp (RGD) peptides; the macromolecular DnBP-BSA was unable to bind nuclear TRs, but still promoted cell proliferation to 104.18% and up-regulated c-fos by 2.99-fold (p < 0.01); after silencing TRbeta gene, cell proliferation (106.64%, p < 0.05) and up-regulation of c-fos (1.23-fold, p < 0.01) were also observed. All of these findings indicated the existence of non-genomic pathway for DnBP-induced thyroid disruption. Finally, DnBP activated the downstream extracellular regulated protein kinases (ERK1/2) pathway, up-regulating Mapk1 (1.15-, p < 0.05), Mapk3 (1.26-fold, p < 0.01) and increasing protein levels of p-ERK (p < 0.01); notably, DnBP-induced ERK1/2 activation along with c-fos up-regulation were attenuated by PD98059 (ERK1/2 inhibitor). Taken together, it could be suggested that integrin alphavbeta3 and ERK1/2 pathway play significant roles in DnBP-induced thyroid disruption, and this novel mechanism warrants further investigation in living organisms. PMID- 30286536 TI - Thermo-activated peroxydisulfate oxidation of indomethacin: Kinetics study and influences of co-existing substances. AB - The widespread occurrence of non-steroidal anti-inflammatory drugs (NSAIDs) (e.g., Indomethacin) in the ambient environment has attracted growing concerns due to their potential threats to ecosystems and human health. Herein, we investigated the degradation of indomethacin (IM) by thermo-activated peroxydisulfate (PDS). The pseudo first-order rate constant (kobs) of degradation of IM was increased significantly with higher temperatures and PDS doses. Moreover, when the initial pH value was raised from 5 to 9 the IM degradation was initially decreased and then increased. Basic conditions were favorable for the removal of IM in the thermo-activated peroxydisulfate system. A response surface methodology based on the Box-Behnken design (BBD) was successfully employed for the optimization of the thermo-activated peroxydisulfate (PDS) system. The presence of chlorine ions manifested a dual effect on the degradation of IM, while bicarbonate and SRFA (as a NOM model) reduced it. Radical scavenging tests and electron spin resonance (ESR) revealed that the dominant oxidizing species were SO4- and OH at pH 9. Furthermore, the TOC removal efficiency attained 28.8% and the release of Cl-was 38.5% at 60 degrees C within 24min, while the mineralization rate of IM were 85.5% with the PDS concentration up to 20 mM at 2 h oxidation. To summarize, thermo-activated PDS oxidation is a promising technique for the remediation of IM-contaminated water. PMID- 30286537 TI - The role of arbuscular mycorrhiza in mercury and mineral nutrient uptake in maize. AB - This work aimed to study the role of arbuscular mycorrhizal fungi (AMF) in Hg and major mineral nutrient uptake and tissue localization of these elements in the roots of maize plants. Maize plants were grown in pots filled with non- and Hg contaminated substrate (50 MUg Hg g-1 as HgCl2) and inoculated with two types of AMF inocula: a) Glomus sp. originating from Hg-polluted soil of a former Hg smelting site in Idrija, Slovenia, and b) commercial AM inoculum Symbivit. Controls were inoculated by corresponding bacterial extracts only. Tissue localization of Hg and major mineral nutrients was performed by laser ablation inductively coupled plasma-mass spectroscopy (LA-ICP-MS) on cryofixed and freeze dried root cross-sections. AMF colonization increased plant biomass in non contaminated substrate, while this effect was not seen in Hg-contaminated substrate. Hg increased total plant biomass more than AMF inoculation, possibly through hormetic effects. AMF increased Hg uptake into the roots, as well as Hg transfer to the shoots. AMF affected plant mineral nutrient uptake, depending on the type of AMF inoculum and the presence of Hg. In the roots, Hg was mainly localized in rhizodermis and endodermis, followed by the cortex and the central cylinder. Higher Hg concentrations were detected in the central cylinder of AM plants than in that of the controls, pointing to a higher Hg mobility and potential bioavailability in AMF inoculated plants. PMID- 30286538 TI - Toxic responses of zebrafish (Danio rerio) to thallium and deltamethrin characterized in the electrocardiogram. AB - The electrocardiogram (ECG) has been widely used to objectively address the physical condition as an index of stress. Though a numerous accounts of investigations on aquatic organisms' ECGs have been made, differentiation of ECG parameters in responding to specific toxic chemicals has not been extensively studied. In this research, it is hypothesized that zebrafish (Danio rerio) ECG parameters would differently respond to different types of pollutants, a heavy metal, thallium (Tl, 0.10 and 13.00 MUg/L) and an organic chemical, deltamethrin (DM, 0.52 and 2.00 MUg/L). Based on the SOM training and statistical analyses, QRS complex could be specified as an indicator of Tl stress, while QT interval might be used to evaluate DM stress. Pearson correlation analysis indicated that QRS complex and QT interval were significantly associated with Tl stress (r = 0.854, p = 0.0002) and DM stress (r = 0.792, p = 0.001), respectively. QRS complex and QT interval had the highest R2, the minimum of SSE and the lowest AIC value in Tl and DM treatments, respectively. Bases on the current experimental results and previous reports, QRS complex and QT interval could be considered as a specific indicator of Tl and DM disturbances in the environment, respectively. PMID- 30286539 TI - Sr isotope fingerprinting of multiple water-source characterizations and its environmental implications in a complex lake-groundwater system, Wudalianchi, Northeast China. AB - The Wudalianchi UNESCO Global Geopark (Northeast China) is famous for its rare cold mineral springs and its associated five hydrologically connected barrier lakes. During this study, strontium (Sr) isotopes (87Sr/86Sr) were studied along with other geochemical data to determine the source of water within the region's deep and shallow mineral springs, shallow wells, and lakes. These waters were characterized by a relatively narrow range of 87Sr/86Sr ratios (0.70648-0.70816). Those ratios were not different in shallow and deep mineral spring waters, and probably reflect ratios associated with potassium volcanic rocks in the area as expected. When combined with 1/Sr ratios, it appears that the shallow mineral springs were derived from upwelling of deep mineral springs and had a composition as an endmember of other waters. Shallow mineral springs and wells exhibited large variations in Cl-/Sr2+ and NO3-/Sr2+ ratios, owing to the input of fertilizers. Farmland runoff and waters from Yaoquan Lake that drains an agricultural area also appear to have been influenced by fertilizers and showed 87Sr/86Sr ratios intermediate between wells and mineral springs. Sewage input is likely responsible for this difference and a slight elevation of the ratios in the wells. The Wudalianchi lakes had similar variations in 87Sr/86Sr and 1/Sr ratios, suggesting their rapid response to terrestrial runoff and the supply of shallow mineral springs. Strontium isotope data can be combined with water chemistry to emphasize water-rock interaction and refine the region's existing model of water interaction in surface and subsurface environments. PMID- 30286540 TI - Aqueous removal of inorganic and organic contaminants by graphene-based nanoadsorbents: A review. AB - Various graphene-based nanoadsorbents, including graphenes, graphene oxides, reduced graphene oxides, and their nanocomposites, have been widely studied as potential adsorbents due to their unique physicochemical properties, such as structural variability, chemical strength, low density, and the possibility of large scale fabrication. Adsorption mechanisms are governed largely by the physicochemical properties of contaminants, the characteristics of nanoadsorbents, and background water quality conditions. This review summarizes recent comprehensive studies on the removal of various inorganic (mainly heavy metals) and organic contaminants by graphene-based nanoadsorbents, and also discusses valuable information for applications of these nanoadsorbents in water and wastewater treatment.

AB - Based on chemical fingerprinting and other lines of scientific evidence, a former pesticide manufacturing plant in Newark, New Jersey (U.S.A.) has been implicated in numerous journal articles as the major source of 2,3,7,8-tetrachlorodibenzo-p dioxin (TCDD) in the sediments of the Lower Passaic River (LPR). Although the site has been extensively studied for over three decades, no previous study has identified a pathway capable of discharging an amount of 2,3,7,8-TCDD comparable to the mass estimates made for 2,3,7,8-TCDD in the sediments of the LPR and Newark Bay, or examined the timing of specific manufacturing processes at the site in relation to 2,3,7,8-TCDD concentrations in dated sediment cores. A reconstruction of the historical operations at this site was performed, supporting it as the major source of 2,3,7,8-TCDD to the LPR. A 2,4,5 trichlorophenol purification process, utilized prior to September 1954, was specifically identified as a significant source of 2,3,7,8-TCDD to the LPR. This purification process generated a dioxin-rich sludge that was discharged to the river prior to September 1954. Annual 2,4,5-trichlorophenol production, coupled with modeling to predict concentrations of 2,3,7,8-TCDD, indicate that 2,3,7,8 TCDD discharges to the LPR from this one process (20-80 kg) are consistent with mass estimates of 2,3,7,8-TCDD in the river (30-50 kg). 2,3,7,8-TCDD and cesium 137 data from nearby sediment cores support this purification process as a major pathway by which 2,3,7,8-TCDD entered the river.

AB - Beaked redfish (Sebastes mentella) and Greenland halibut (Reinhardtius hippoglossoides) were collected in waters around Svalbard (Barents Sea) to study the influence of different muscle separation/filleting techniques at small and medium fishes on the dioxin/PCB content. Sampling of both species included preparation techniques such as fillets with or without belly flaps, commercially trimmed fillets and cutting into anterior and posterior cutlets. In case of Greenland halibut also the whole edible muscle part and middle cutlets were studied. All samples analysed were far below the maximum level of 6.5 pg/g wet weight (ww) WHO-PCDD/F-PCB-TEQ and 75 ng/g ww ndl-PCB. Trimmed fillets of beaked redfish had the lowest fat content and the lowest level of dioxins and PCB (1.70%, WHO-PCDD/F-PCB-TEQ = 0.320 pg/g ww). The respective posterior cutlets showed the highest fat content and highest levels of dioxins and PCB (2.66%, WHO PCDD/F-PCB-TEQ = 0.729 pg/g ww). Levels of dioxins and PCB in Greenland halibut samples were generally higher and ranged between WHO-PCDD/F-PCB-TEQ = 0.784 pg/g ww (fillets without bells flaps, fat content = 8.83%) and WHO-PCDD/F-PCB-TEQ = 2.022 pg/g ww (edible part whole muscle, fat content = 8.62%). The results show a considerable influence of the different sampling methods on the dioxin and PCB levels of the species analysed. PMID- 30286544 TI - Adsorption removal of anionic dyes from aqueous solutions by chitosan nanoparticles deposited on the fibrous carrier. AB - The synthesis, characterization and environmental application of chitosan based material stable in acidic media for adsorption of anionic dyes were investigated. The adsorption material is chitosan nanoparticles immobilized on a fibrous carrier (CPF). The choice of optimal conditions for the preparation of chitosan particles and their immobilization on a chemically activated polyethylene terephthalate (PET) fiber is justified. Immobilized nanoparticles showed high adsorption rates and dye binding capacity (300-1050 mg g-1) depending on the dye type. Anionic phthalocyanine dyes having different molecular sizes, different nature and number of anionic groups were used as model adsorbates. The experimental isotherm data and a linear correlation coefficients (rL2 > 0.99) have shown that the dyes adsorption on CPF is best predicted by the Langmuir isotherm. The adsorption rate has been found to conform to pseudo-second-order kinetics with a good correlation (R2 > 0.99) with intra-particle diffusion as one of the rate determining steps. It has been is established that the sorption rate and the limiting sorption capacity decrease with the increment in the dye molecule size. The process of adsorption of the dyes on the CPF is pH-insensitive in the pH range of 2-8. The adsorption saturated CPF could be effectively regenerated by a simple alkaline washing. PMID- 30286543 TI - Occurrence, removal and risk assessment of steroid hormones in two wastewater stabilization pond systems in Morogoro, Tanzania. AB - The present study investigated the occurrence and removal of 10 steroid hormones (4 androgens, 3 progestagens and 3 estrogens) in two WSP systems, Mafisa and Mzumbe in Morogoro, Tanzania. All 10 steroid hormones were detected in the influent of both WSP systems in the dry as well as in the rainy season. The concentrations of steroids in influent wastewater ranged from 0.1 ng/L for 17-OH pregnenolone to 445 ng/L for estrone and from below limit of detection for 17-OH pregnenolone to 45 ng/L for estrone in effluent. During dry season, the overall mean +/- standard deviation removal efficiency for the 10 steroids were 70 +/- 21% for Mzumbe WSP and 97 +/- 3% for Mafisa WSP. During the rainy season the overall mean removal efficiency for all the steroid hormones were 52 +/- 32% for Mzumbe WSP and 94 +/- 8% for Mafisa WSP. Risk was characterized by calculating the risk quotients (RQs) for fish and humans. 46% of the total RQs calculated were above one, indicating high risk. Low RQs were estimated for androgens and progestagens but the estrogen concentrations measured in the WSP systems and Morogoro River indicated a high risk for fish. However, estrogens appeared not to pose an appreciable risk to human health from water intake and fish consumption. The results indicated that WSP systems are quite effective in removing steroid hormones from wastewater. Thus, low technology systems such as WSP systems are suitable techniques in low income counties due to relatively low costs of building, operating and maintaining these systems. PMID- 30286545 TI - Spatiotemporal variation and potential risks of seven heavy metals in seawater, sediment, and seafood in Xiangshan Bay, China (2011-2016). AB - The residues and risks of heavy metals in the environment and organisms have attracted great concern for many years. However, the information on their long term spatiotemporal trends and potential health and ecological risks are scarce. In this study, a total of 1815 seawater samples, 451 sediment samples, and 54 seafood samples were collected in Xiangshan Bay, China, between 2011 and 2016. The residue, distribution, seasonal variation, and potential health risks of seven heavy metals in seawater, sediment, and seafood were evaluated. Dissolved Zn (mean = 16.8 MUg L-1) and Cu (mean = 3.4 MUg L-1) concentrations were high in seawater. Sediments were mainly contaminated by Zn (mean = 120.8 mg kg-1) and Cr (mean = 81.7 mg kg-1). The highest levels of Cu and Zn were observed in Ostreidae with the concentrations of 84.3 and 99.0 mg kg-1, respectively. The Kendall test indicated that only As, Cu, Cd, and Hg showed decreasing trends in seawater with time and no significant temporal trends were identified for heavy metals in sediment between 2011 and 2016. Only As may pose non-carcinogenic risks to both adults and children in some seafood. These data provide a reliable reference for government to use in developing reasonable and scientific regulations on the ecological and food safety of this area. PMID- 30286546 TI - Investigation of reactive oxygen species produced by microwave electrodeless discharge lamp on oxidation of dimethyl sulfide. AB - Microwave electrodeless discharge lamp (MEDL) has been regarded as a powerful light source of photoreaction. Four kinds of chemicals, nitrogen (N2), oxygen (O2), water (H2O) and dimethyl sulfide (DMS), were used as molecular probes to explore the generation process of reactive oxygen species (ROS) and their photo oxidation performances on the photodegradation of organic pollutants with application of an exterior MEDL system. ROS such as O (3P), O3, O (1D) and 1O2 were generated via irradiation of O2 and H2O except dry N2 by MEDL. They were transformed to other ROS including .OH and H2O2 with increase of relative humidity. The ROS productivity was inhibited evidently by humidity and .OH became the major active species at high humidity. An optimal mineralization rate of 23.6% for DMS photodegradation was reached in dry air compared with 8.74% at high humidity, which indicated that O (1D) and 1O2 were more powerful oxidants than O3 and OH. The results showed that the higher mineralization rate of organic pollutants was obtained by increasing the generation efficiency of ROS of O (1D) and 1O2. Furthermore, the results provided an alternative to develop intensification technology on photodegadation of organic pollutants with MEDL system and an optimal operation process including photocatalyst and humidity. PMID- 30286547 TI - On-site treatment of flowback and produced water from shale gas hydraulic fracturing: A review and economic evaluation. AB - On-site flowback treatment systems are typically rated and selected based on three fundamental categories: satisfying customer needs (e.g. meeting effluent quality, capacity, delivery time and time required to reach stable and steady effluent quality), common features comparison (e.g. treatment costs, stability of operation, scalability, logistics, and maintenance frequency) and through substantial product differentiation such as better service condition, overcoming current market limitations (e.g. fouling, salinity limit), and having lower environmental footprints and emissions. For treatment of flowback, multiple on site treatment systems are available for primary separation (i.e. reducing TSS concentrations and particle size below 25 MUm for disposal), secondary separation (i.e. removing TSS, iron and main scaling ions, and reducing particle size up to 5 MUm for reuse), or tertiary treatment (i.e. reducing TDS concentration in the permeate/distillate to below 500 mg/L) for recycling or discharge. Depending on geographic features, frac-fluid characteristics, and regulatory aspects, operators may choose disposal or reuse of flowback water. Among these approaches, desalination is the least utilized option while in the majority of cases on-site basic separation is selected which can result in savings up to $306,800 per well. Compared to desalination systems, basic separation systems (e.g. electrocoagulation, dissolved air floatation) have higher treatment capacity (159 4133 m3/d) and specific water treatment production per occupied space (8.9-58.8 m3/m2), lower treatment costs ($2.90 to $13.30 per m3) and energy demand, and finally generate less waste owing to their high recovery of 98-99.5%, which reduces both operator costs and environmental burdens. PMID- 30286548 TI - Integrative analysis of methylome and transcriptome variation of identified cardiac disease-specific genes in human cardiomyocytes after PM2.5 exposure. AB - PM2.5 exposure is strongly linked to cardiac disease. Subtle epigenetic or transcriptional alterations induced by PM2.5 might contribute to pathogenesis and disease susceptibility of cardiac disease. It is still a major challenge to identify biological targets in human genetics. Human cardiomyocytes AC16 was chosen as cell model. Epigenetic effect of PM2.5 in AC16 was analyzed using Illumina HumanMethylation 450 K BeadChip. Meanwhile the transcriptomic profiling was performed by Affymetrix(r) microarray. PM2.5 induced genome wide variation of DNA methylation pattern, including differentially methylated CpGs in promoter region. Then gene ontology analysis demonstrated differentially methylated genes were significantly clustered in pathways in regulation of apoptotic process, cell death and metabolic pathways, or associated with ion binding and shuttling. Correlation of the methylome and transcriptome revealed a clear bias toward transcriptional suppression by hypermethylation or activation by hypomethylation. Identified 386 genes which exhibited both differential methylation and expression were functionally associated with pathways including cardiovascular system development, regulation of blood vessel size, vasculature development, p53 pathway, AC-modulating/inhibiting GPCRs pathway and cellular response to metal ion/inorganic substance. Disease ontology demonstrated their prominent role in cardiac diseases and identified 14 cardiac-specific genes (ANK2, AQP1 et al.). PPI network analysis revealed 6 novel genes (POLR2I, LEP, BRIX1, ADCY6, INSL3, RARS). Those genes were then verified by qRT-PCR. Thus, in AC16, PM2.5 alters the methylome and transcriptome of genes might be relevant for PM2.5-/heart associated diseases. Result gives additional insight in PM2.5 relative cardiac diseases/associated genes and the potential mechanisms that contribute to PM2.5 related cardiac disease. PMID- 30286549 TI - Arsenic exposure, profiles of urinary arsenic species, and polymorphism effects of glutathione-s-transferase and metallothioneins. AB - This study assessed the effects of polymorphic variants of gutathione-S transferase and metallothioneins on profiles of urinary arsenic species. Drinking groundwater from Margarita and San Fernando, Colombia were analyzed and the lifetime average daily dose (LADD) of arsenic was determined. Specific surveys were applied to collect demographic information and other exposure factors. In addition, GSTT1-null, GSTM1-null, GSTP1-rs1695 and MT-2A-rs28366003 genetic polymorphisms were evaluated, either by direct PCR or PCR-RFLP. Urinary speciated arsenic concentrations were determined by HPLC-HG-AFS for species such as AsIII, AsV, monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), and total urinary As (TuAs). Primary methylation index (PMI) and secondary methylation index (SMI) were also calculated as indicators of the metabolic capacity. Polymorphisms effects were tested using multivariate analysis, adjusted by potential confounders. The As concentrations in groundwater were on average 34.6 +/- 24.7 MUg/L greater than the WHO guideline for As (10 MUg/L). There was a correlation between As concentrations in groundwater and TuAs (r = 0.59; p = 0.000). Urinary inorganic arsenic (%InAs) was associated with GSTP1, LADD, GSTP1*Age, GSTP1*alcohol consumption (r2 = 0.43; likelihood-ratio test, p = 0.000). PMI was associated with sex (r2 = 0.20; likelihood-ratio test, p = 0.007). GSTP1 (AG + GG) homozygotes/heterozygotes could increase urinary %InAs and decrease the PMI ratio in people exposed to low and high As from drinking groundwater. Therefore, the explanatory models showed the participation of some covariates that could influence the effects of the polymorphisms on these exposure biomarkers to As. PMID- 30286550 TI - Induced-fit adsorption of diol-based porous organic polymers for tetracycline removal. AB - Adsorption is recognized as one of the most efficient approaches for antibiotics removal from water. Inspired by the enzyme-substrate interaction model, we proposed induced-fit adsorption (IFA) model, and rationally designed and fabricated diol-based porous organic polymers (POPs) as adsorbents for tetracycline (TC) removal. For 2,3-naphthalenediol-based POP (NTdiol-POP), the preferable geometry of diol-groups contributed to the high binding energy with TC species and flexible methylene linkages between neighboring rigid naphthalene rings gave rise to precisely matching between TC species and adsorbents, that is, the induced-fit conformation change. As a result, NTdiol-POP exhibited a high saturated adsorption capacity of 155.8 mg g-1. More importantly, NTdiol-POP exhibited excellent TC removal efficiencies in both concentrated solution (96% for 4 p.p.m) and trace level solution (97% for 250 p.p.b). PMID- 30286551 TI - Debromination of 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) by synthetic Pd/Fe0 and Cu/Fe0 in different protic solvents. AB - Polybrominated diphenyl ethers (PBDEs) belong to a class of persistent organic pollutants (POPs), with potential toxicity to the liver, reproductive system, and development of mammals. The highly toxic and concentrated congener, 2,2',4,4' tetrabromodiphenyl ether (BDE-47), was chosen to investigate debromination mechanisms by the two synthetic iron-based bimetals (Pd/Fe0 and Cu/Fe0) in two protic solvents (water and ethanol). SEM, XPS, and BET analyses showed that the synthetic bimetals Pd/Fe0 and Cu/Fe0 were spherical with diameters of about 100 nm and loaded with ~1% (wt%) of Pd and Cu, respectively. GC-MS was used for the analysis of degradation products and the chromatograms showed that both Pd/Fe0 and Cu/Fe0 bimetals had effective reducing properties in water solvent. In ethanol solvent, debromination of BDE-47 by Pd/Fe0 showed a similar high activity, but BDE-47 could be hardly degraded by Cu/Fe0. The dominant debromination products of BDE-47 by Pd/Fe0 and Cu/Fe0 were ortho-substituted and para-substituted BDEs, respectively. Active H-atomic transfer was found to play a key role in the debromination of BDE-47 by Pd/Fe0 in both, water and ethanol, with a preference for para-debromination along with the formation of dibenzo-p furan (DF) as the by-product, mainly in water. In contrast, electron transfer with a preference for ortho-debromination was found to play a predominant role for Cu/Fe0 system in water. More importance should be provided to active H-atomic transfer for its high efficiency. In-depth study on the mechanism of formation of by-product DF would be significant for its higher toxicity, possibility of accumulation and migration in the environment. PMID- 30286552 TI - Sulfur autotrophic denitrification (SAD) driven by homogeneous composite particles containing CaCO3-type kitchen waste for groundwater remediation. AB - This study first developed homogeneous sulfur/buffer composite particles to obtain an alkalinity-uniform and cost-effective sulfur autotrophic denitrification (SAD) technology. As single solid-phase material, the composites performed better in enrichment of microorganisms and stabilization of S/C ratio throughout the reaction. Natural CaCO3-type kitchen waste, used as a buffer in the developed composites, was conducive to providing rich metal nutrients (K, Na, Mg, Al, and Ca) for the metabolism of microorganisms. Maximum denitrification efficiency of 96.4%, 96.8% and 96.8% were obtained by the 1.25:1 PSL, 1.72:1 PSE and 1.25:1 PSS composites, respectively, and nitrate removal rates of >0.6 mg-N/L h and stable pH between 6.20 and 8.00 were achieved. The S0-eggshell microcosms showed more significant accumulations of ammonium-N and sulfate, reaching ~1.2 mg N/L and 405.99 +/- 9.47 mg/L, respectively. When dealing with nitrate in real groundwater, the composites showed a great advantage over the dispersed materials at a denitrification efficiency of more than 99.7% and rate of 0.40 mg-N/L-h. No ammonium was observed by PSE and PSS throughout the batch. This study confirmed the potential of waste composites to enhance SAD performance in nitrate contaminated groundwater remediation. PMID- 30286553 TI - Multi-scale analysis of heavy metals sources in soils of Jiangsu Coast, Eastern China. AB - Since the development of Jiangsu Coast was proposed as a national strategy by the Chinese Government in 2009, Jiangsu Coast has been experiencing rapid and intensive development in industry and tidal flat reclamation, which has inevitably led to the accumulation of heavy metals in its soils. A total of 239 samples (0-20 cm) were collected from topsoils of Jiangsu Coast, and their concentrations of Cd, Cr, Cu, Hg, Ni, Pb, and Zn were determined. Factorial kriging was applied to examine the scale-dependent correlations between heavy metals and to generate the spatial components at multiple scales, and multivariate stepwise regression was used to explore the relationships between the spatial multi-scale components of heavy metals and environmental factors. Linear model of co-regionalization (LMC) fitting indicated that the multi-scale variation comprised a nugget effect, an exponential structure with a range of 15 km (local scale), and a spherical structure with a range of 135 km (regional scale). The spatial correlations of seven heavy metals depended on their spatial scales, and their correlations increased with the increasing scales. Spatial variations in Cr and Ni were associated with natural geochemical sources on both local and regional scales. Parent material influenced the basic spatial variations in Cd, Cu, Pb and Zn on both local and regional scales, but human activity also contributed to the spatial variations in these four metals. The human inputs of Cd, Cu, Pb, and Zn differed on these two scales. Hg was dominated by industrial emissions and agricultural practices on both scales. PMID- 30286554 TI - Atrazine induced oxidative stress and mitochondrial dysfunction in quail (Coturnix C. coturnix) kidney via modulating Nrf2 signaling pathway. AB - Atrazine (ATR) is a most used herbicide which is believed as a pivotal determinant of environmental nephrosis, but potential mechanism is still largely unclear. This study intends to reveal a novel mechanism of ATR-induced nephrotoxicity. Quail were treated with 0, 50, 250 and 500 mg ATR/kg/d by oral gavage for 45 days. Kidney coefficient was decreased, biochemical and morphologic indices reflecting the kidney injury were significantly increased in ATR-exposed quail. ATR exposure upregulated the expression of proapoptotic factors (Bax, Caspase 3 and FasL) and downregulated antiapoptotic factor (Bcl-2). Notably, cristae of mitochondria decreased, mitochondrial malformation and mitochondrial vacuolar degeneration were observed in ATR-exposed quail. ATR induced the disorder of mitochondrial function related factors expressions and promoted oxidative damage. Furthermore, ATR induced toxicities in the expression of Nrf2 and Nrf2-target genes. In conclusion, ATR altered the microstructure and function of quail kidney. ATR induced renal damage via causing mitochondrial dysfunction, influencing mitochondrial function related genes expression, modulating Nrf2 signaling pathway. This study suggested ATR induced the nephrotoxicity via disturbing the transcription of mitochondrial function related factors and Nrf2 signaling pathway. PMID- 30286555 TI - Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans associated with settling particles in Lake Ontario. AB - Sediment traps were deployed at seven sites in the western and central basins of Lake Ontario for calculation of concentrations and down fluxes for polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) to assess ongoing loadings to Lake Ontario from the Niagara River watershed. Traps were deployed at multiple depths (beginning at 20 m) during two seasonal time periods at stations impacted by the outflow of the Niagara River, and stations reflecting deeper water offshore conditions. Settling particles were collected seasonally to assess the influence of physical characteristics of the water column, i.e., isothermal conditions vs. stratified conditions, on concentrations and fluxes of PCDD/Fs. At all stations and for all depth intervals, PCDD/F concentrations were higher in the winter sampling period (range of 3120-10,600 pg g-1), compared to the spring - summer - fall time period (range of 320-6900 pg g-1). These results indicated bottom sediments in central and western Lake Ontario were more highly contaminated, compared to contemporary particulate material entering the lake via the Niagara River or resulting from shoreline erosion. However, assessment of PCDD/F congener profiles and ratios also indicated source areas within the Niagara River watershed continued to episodically contribute loadings to Lake Ontario. The results also indicated changes in discharges of PCDD/Fs from sources in the Niagara River result in changes in congener profiles in settling particles, which can be detected by continued monitoring.

AB - Lead (Pb) poisoning in raptors and water birds is a serious problem in many countries. However, only a small fraction of Pb poisoning has been detected in birds. Bone specimens may be useful indices of Pb exposure because bones contain ~90% of the total Pb body burden. The original purpose of this study was to comprehensively analyze Pb accumulation in various bone types using inductively coupled plasma-mass spectrometry (ICP-MS). Since our results showed that Pb accumulation differed greatly depending on bone type, a secondary objective was defined, aiming to investigate the fine Pb distribution and its relation to bone structure and bone marrow by using laser ablation (LA)-ICP-MS. Our findings suggested that bone samples (1) consisting of trabecular tissue and (2) those that contain bone marrow could accumulate high levels of Pb following acute exposure. The shorter turnover time of trabecular bone can cause a rapid accumulation of Pb, and bone marrow may have an important role for internal exposure of Pb to bone tissue. Pb is accumulated in bones via blood flow, and bone marrow receives blood from outside the bones. In conclusion, bone samples provide valuable information on Pb exposure and could be useful to investigate and understand mortalities related to suspected Pb poisoning. PMID- 30286558 TI - The Beneficial Effects of alpha-Lipoic Acid in Critically Ill Patients: A Prospective, Randomized, Double-Blind, Placebo-Controlled Trial. AB - BACKGROUND: Critical illness is associated with oxidative stress and insulin resistance. These conditions affect the clinical outcomes in intensive care unit (ICU). The aim of this study was to determine whether intervention with alpha lipoic acid (ALA) influences the oxidative stress, insulin resistance, and clinical outcomes in critically ill patients. METHOD: In this randomized double blind placebo-controlled trial, 80 critically ill patients who were expected to stay at least seven days in the ICU and required enteral feeding were randomly allocated to two equal groups to receive either ALA (900 mg) or placebo daily for 10 days. Serum levels of total antioxidant capacity (TAC), malondialdehyde (MDA), insulin, glucose (GLC), C-reactive protein (CRP), albumin (Alb), prealbumin (preAlb), total protein (total-pr) and total lymphocyte count (TLC) as well as homeostasis model assessment-estimated insulin resistance (HOMA-IR) were measured at baseline and at the end of ALA supplement phase. Clinical outcomes (length of ICU/hospital stay, ICU/hospital mortality, and 28-day mortality and ventilator free days) were also recorded. RESULTS: TAC increased significantly in the ALA supplemented group compared to the placebo group (p < 0.001). Moreover, serum levels of GLC decreased significantly in the ALA group compared to lack of changes in the placebo group (p = 0.011). ALA supplementation also hindered an increase in HOMA-IR (p = 0.015). There were no significant differences in other biochemical markers and clinical outcomes between the two groups. CONCLUSION: ALA may be an effective supplement to improve antioxidant defense and insulin resistance in critically ill patients. PMID- 30286559 TI - Enhanced Perioperative Safety and Comfort During Airway-Related Surgeries and Procedures With Dexmedetomidine-A Brief Review and Clinical Practice Experience. AB - Dexmedetomidine, an alpha-2 adrenergic receptor agonist, provides analgesia, sedation, anxiolysis, sympatholysis and anesthetic-sparing effect, without inducing significant respiratory depression. Due to these properties, its clinical use is no longer limited to serving as a sedative agent in the intensive care unit. Proper airway management and the avoidance of cardiac and respiratory complications are common goals of everyday anesthesia practice. Ensuring airway safety is pivotal during the anesthesia stages of induction, maintenance and recovery. In this review, we focus on the advantages of dexmedetomidine in awake fiberoptic intubation (AFOI), diagnostic examinations and surgeries of patients with obstructed airways, and reducing emergence delirium effectively without causing further adverse events. With increasing implementation in different anesthetic scenarios, dexmedetomidine provides a favorable option to enhance patient safety and comfort.

AB - Central venous catheterization (CVC) is a common invasive procedure. Although it is a relatively safe procedure, severe complications occurred sometimes. One of the most serious complications is large vessel perforation. A 40-year-old man was send to intensive care unit (ICU) after liver transplantation surgery with massive blood transfusion. Four days later, chest computed tomography (CT) were arranged for unknown leukocytosis and high level of procalcitonin. Chest CT revealed possibility of innominate vein perforation by CVC. Surgeon confirmed the malposition of CVC complicated perforation and repaired innominate vein. Unfortunately, the patient passed away 8 days later after this re-operation even initially better condition after aggressive treatment. Delayed malposition of CVC is a rare cause for CVC complications. To minimize incidence of this severe complication, catheterization should be performed very carefully and post procedure position checking is indicated.

AB - Primary rhabdomyosarcoma (RMS) of the breast is very rare, which often leads to delayed histologic confirmation. Here, we report two cases of primary RMS of the breast: spindle cell/sclerosing (ssRMS) and alveolar (aRMS). These two primary RMS patients were teenage girls who underwent mastectomy. The patient with ssRMS experienced recurrence at the operative site four months after surgery despite concurrent chemoradiation therapy. The aRMS patient had multiple metastatic lesions at the time of diagnosis and an association with FAX3-FOXO1 (FKHR) fusion transcripts; she died 22 months post-diagnosis. This is the second report of primary ssRMS of the breast. We also reviewed all published literature concerning primary RMS of the breast. PMID- 30286563 TI - The Expression of Adipophilin Is Frequently Found in Solid Subtype Adenocarcinoma and Is Associated with Adverse Outcomes in Lung Adenocarcinoma. AB - BACKGROUND: The up-regulation of the lipogenic pathway has been reported in many types of malignant tumors. However, its pathogenic role or clinical significance is not fully understood. The objective of this study was to examine the expression levels of adipophilin and related hypoxic signaling proteins and to determine their prognostic impacts and associations with the pathologic characteristics of lung adenocarcinoma. METHODS: Expression levels of adipophilin, heat shock protein 27 (HSP27), carbonic anhydrase IX, and hypoxia inducible factor 1alpha were examined by immunohistochemical staining using tissue microarray blocks. Correlations between protein expression levels and various clinicopathologic features were analyzed. RESULTS: A total of 230 cases of primary adenocarcinoma of the lung were enrolled in this study. Adipophilin expression was more frequent in males and with the solid histologic type. It was correlated with HSP27 expression. Patients with adipophilin-positive adenocarcinoma showed a shorter progression-free survival (PFS) (median PFS, 17.2 months vs 18.4 months) in a univariable survival analysis, whereas HSP27 positivity correlated with favorable overall survival (OS) and PFS. In a multivariable analysis, adipophilin and HSP27 were independent prognostic markers of both OS and PFS. CONCLUSIONS: Activated lipid metabolism and the hypoxic signaling pathway might play a major role in the progression of lung adenocarcinoma, especially in the solid histologic type.

PMID- 30286565 TI - Clinical characteristics in Japanese children with nonobese type 2 diabetes. AB - It is well known that the incidence of youth-onset type 2 diabetes is increasing worldwide. On the other hand, most studies have shown that the majority of youth onset type 2 diabetes occurs in obese individuals, generally with a body mass index (BMI) greater than the 90th or 95th centile for sex- and age-matched children and adolescents. However, we identified some Japanese children with nonobese type 2 diabetes and BMI less than 90th centile by a urine glucose screening program at schools in the Tokyo Metropolitan Area. According to the results obtained from the screening, clinical characteristics of patients with nonobese type 2 diabetes seemed to be different from those in obese type 2 diabetes. Nonobese patients tended to show lower insulin secretion abilities and milder, but evident, insulin resistance from the time of diagnosis. Female, low birth weight (small for gestational age), and genetic background, not related to beta-cell-associated autoimmunity, may play a role in development of nonobese type 2 diabetes. In addition, nonobese patients tend to progress earlier to pharmacological treatment including oral hypoglycemic drugs and insulin. Further studies are needed to confirm to these findings and clarify the pathophysiology of children with nonobese type 2 diabetes. PMID- 30286566 TI - Type 2 diabetes mellitus in children and adolescent: an Indonesian perspective. AB - The prevalence of type 2 diabetes mellitus (T2DM) in children and adolescents has increased globally over the past 2 decades. Metabolic syndrome, including obesity and overweight at a young age, increases the occurrence of T2DM. Studies in Indonesia have found that obese children and adolescents are more likely to have insulin resistance, a risk factor for T2DM. There are no data on the current incidence of T2DM in youth in Indonesia, but there has been a significant rise in the prevalence of overweight in adolescents. The diagnosis of T2DM in youth is similar to that in adults, with special consideration of when to test asymptomatic children. Management of T2DM in Indonesia follows the recommendations of the Indonesian Pediatric Society, which include lifestyle modifications, such as improving dietary habits and exercise, as well as appropriate medications. Metformin is the drug of choice for young T2DM patients; if marked hyperglycemia is present, basal insulin is given with metformin. Monitoring of T2DM is generally done through selfmonitoring of blood glucose and glycosylated hemoglobin. PMID- 30286567 TI - Childhood diabetes in India. AB - This review describes the epidemiology of childhood diabetes in India. It focuses on the incidence and prevalence of type 1 diabetes and its complications and comorbid conditions. The review also covers data related to type 2 diabetes, glucose intolerance, and monogenic diabetes from India. A brief discussion regarding unique contributions from India to the world literature is included. The topics discussed include use of camel milk as adjuvant therapy in type 1 diabetes, relevance of the A1/A2 hypothesis, and comprehensive clinico etiopathological classification of type 1 diabetes. PMID- 30286568 TI - Therapeutic potential of alpha-1 antitrypsin in human disease. AB - Alpha-1 antitrypsin (AAT), an alpha globulin glycoprotein, is a member of the serine protease inhibitor (serpin) superfamily. The clinical significance of AAT is highlighted by AAT deficiency. Genetic deficiency of AAT can present as several neutrophilic diseases associated with emphysema, liver cirrhosis, panniculitis, and systemic vasculitis. Recently, animal and human studies have shown that AAT can control inflammatory, immunological, and tissue-protective responses. In addition, AAT treatment can prevent overt hyperglycemia, increase insulin secretion, and reduce cytokine-mediated apoptosis of pancreatic beta cells in diabetes. These multifunctional roles of AAT draw attention to the glycoprotein's therapeutic potential for many inflammatory and autoimmune diseases beyond AAT deficiency. As underlying mechanisms, recent studies have suggested the importance of serine protease inhibitory activity of AAT in obesity associated insulin resistance, chronic obstructive pulmonary disease, and cystic fibrosis. In this review, we explore the multiple functions of AAT, in particular, the anti-inflammatory and serine protease inhibitory functions, and AAT's therapeutic potential in a variety of human diseases through published literature. PMID- 30286569 TI - Evaluation of bone mineral status in prepuberal children with newly diagnosed type 1 diabetes. AB - PURPOSE: Many studies have reported that patients with type 1 diabetes have reduced bone mineral density (BMD). We assessed bone status in prepubertal children with type 1 diabetes mellitus (type 1 DM) at initial diagnosis and investigated factors associated with BMD. METHODS: Prepubertal children (n=29) with newly diagnosed type 1 diabetes from 2006 to 2014 were included. Dual-energy X-ray absorptiometry measured regional and whole-body composition at initial diagnosis. BMD was compared with healthy controls matched for age, sex, and body mass index (BMI). RESULTS: The mean age of all subjects (16 boys and 13 girls) was 7.58+/-1.36 years (range, 4.8-11.3 years). Initial mean glycosylated hemoglobin (HbA1c) level was 12.2%+/-1.9%. The mean BMD z-scores of lumbar spine, femur neck, and total body were not significantly different between patients and controls. Three patients (10.3%) had low bone density (total body BMD standard deviation score [SDS] < -2.0). To identify determinants of lumbar spine BMD z score, multivariate regression analysis was performed with stepwise variable selection of age, pubertal status, BMI SDS, insulin like growth factor-1, and HbA1c. Only BMI SDS was significantly correlated with lumbar spine BMD z-score (beta=0.395, P=0.023). CONCLUSION: Prepubertal children with newly diagnosed type 1 DM had similar bone mass compared to healthy peers. However, patients with low BMI should be carefully monitored for bone density in type 1 DM. PMID- 30286570 TI - Thyroid function in obese Korean children and adolescents: Korea National Health and Nutrition Examination Survey 2013-2015. AB - PURPOSE: In recent years, there has been an increasing focus on thyroid function in pediatric obese patients, but no nationwide study evaluating the relationship between thyroid function and obesity has yet been conducted in Korea. We aimed to evaluate thyroid dysfunction in obese Korean children. METHODS: We analyzed the associations between obesity and thyroid hormone levels among 975 Korean boys and girls aged 10-18 years and who participated in the Korean National Health and Nutrition Examination Survey VI (2013-2015). RESULTS: Average serum thyrotropin (TSH) and serum free thyroxine (fT4) levels in the nonobese group were 2.7+/-0.1 MUIU/mL and 1.3+/-0.0 ng/dL, respectively, and those in the overweight group were 3.1+/-0.2 MUIU/mL and 1.2+/-0.0 ng/dL. Serum TSH level was significantly higher in the abdominal obesity group than in the normal group (P=0.023). fT4 level was significantly lower in both the overweight and abdominal obesity groups than in the normal group (P<0.001, P=0.014). Serum TSH level was associated positively with abdominal obesity and levels of high-density lipoprotein cholesterol and triglyceride. Serum fT4 level was negatively correlated with abdominal obesity (P=0.014). CONCLUSION: Korean children with abdominal obesity showed increased TSH and decreased fT4 levels compared to normal children. PMID- 30286571 TI - Factors affecting height velocity in normal prepubertal children. AB - PURPOSE: To analyze the effects of clinical and laboratory factors, including insulinlike growth factor (IGF) levels, on the height velocity of normal prepubertal children. METHODS: Ninety-five healthy prepubertal children (33 boys, 62 girls) were enrolled. The mean chronological age was 6.3+/-1.4 years, with a height standard deviation score (SDS) of -0.88+/-0.70. IGF-1, IGF binding protein 3 (IGFBP-3), SDS for anthropometric measurements, and changes in SDS for anthropometric measurements were analyzed for 1 year, and their associations with 1-year height velocity were investigated. RESULTS: The group of children with a 1 year height velocity of >=6 cm were chronologically younger than the group with a 1-year height velocity of <6 cm (5.9+/-1.3 years vs. 6.7+/-1.3 years, P=0.004), with a lesser increase of SDS for body mass index (BMI) over 1 year (-0.18+/-0.68 vs. 0.13+/-0.53, P=0.014). There were no differences between the 2 groups in IGF 1 SDS and IGFBP-3 SDS. Multiple linear regression showed that baseline chronological age (r=0.243, P=0.026) and height SDS (r=0.236, P=0.030) were positively associated with IGF-1 SDS. Binomial logistic regression showed that an older chronologic age at referral (odds ratio [OR], 0.68; 95% confidence interval [CI], 0.47-0.99) and an increase of BMI SDS over 1 year (OR, 0.41; 95% CI, 0.18 0.89) were associated with a decreased growth possibility of an above-average height velocity (>=6 cm/yr). CONCLUSION: Height velocity of normal prepubertal children is affected by an increase of BMI SDS and chronological age. Prepubertal IGF-1 SDS reflects height SDS at the time of measurement but is not associated with subsequent height velocity. PMID- 30286572 TI - Successful switching from insulin to sulfonylurea in a 3-month-old infant with diabetes due to p.G53D mutation in KCNJ11. AB - Permanent neonatal diabetes mellitus is most commonly caused by mutations in the ATP-sensitive potassium channel (KATP) subunits. Prompt initiation of sulfonylurea treatment can improve glycemic control in children with KCNJ11 mutation. In this report, we present a case of permanent neonatal diabetes caused by a mutation in the KCNJ11 gene that was successfully treated via early switching of insulin to sulfonylurea treatment. A 53-day-old female infant presented with diabetic ketoacidosis. Insulin was administered for the ketoacidosis and blood glucose regulation. At 3 months of age, using genomic DNA extracted from peripheral lymphocytes, direct sequencing of KCNJ11 identified a heterozygous mutation of c.158G>A (p.G53D) and confirmed the diagnosis of permanent neonatal diabetes mellitus. Subsequently, treatment with sulfonylurea was initiated, and the insulin dose was gradually tapered. At 4 months of age, insulin therapy was discontinued, and sulfonylurea (glimepiride, 0.75 mg/kg) was administered alone. At 6 months after initiation of administration of sulfonylurea monotherapy, blood glucose control was stable, and no hypoglycemic events or developmental delays were reported. C-peptide levels increased during treatment with sulfonylurea. Early switching to sulfonylurea in infants with permanent diabetes mellitus owing to a KCNJ11 mutation could successfully help regulate glycemic control, which suggests the need for early genetic testing in patients presenting with diabetes before 6 months of age. PMID- 30286573 TI - Compound heterozygosity for a whole gene deletion and p.R124C mutation in CYP21A2 causing nonclassic congenital adrenal hyperplasia. AB - We present a family with 2 members who received long-term steroid treatment for presumed classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, until molecular testing revealed nonclassic CAH, not necessarily requiring treatment. A 17-year-old male presented to our clinic on glucocorticoid and mineralocorticoid treatment for classic CAH. He was diagnosed at 4 years of age based on mild-moderate elevations of 17-hydroxyprogesterone (17-OHP) and adrenocorticotropic hormone (ACTH), but without evidence of precocious adrenarche/puberty. Due to his diagnosis, his clinically asymptomatic 3-year-old sister was tested and also found to have elevated ACTH and 17-OHP levels and was started on glucocorticoids for classic CAH. Family history revealed a healthy sibling who had no biochemical evidence of CAH and consanguineous healthy parents. We questioned the diagnosis of classic CAH and performed an ACTH1-24 stimulation test, which showed a level of 17-OHP in the borderline range between classic and nonclassic CAH. Molecular testing, using sequencing and multiplex ligation-dependent probe amplification analysis of CYP21A2, revealed that both affected siblings were compound heterozygotes for a whole-gene deletion and a, likely pathogenic (nonclassical), sequence variant, p.R124C. The asymptomatic father had the same genotype, while the mother showed one deleted copy and 2 active copies, making her an asymptomatic carrier. Our report demonstrates the importance of molecular testing in atypical cases of CAH, as well as the importance of both sequencing and deletion analysis. The results of molecular testing should be interpreted in clinical context, and treatment should be prescribed according to guidelines when available.

AB - X-linked adrenal hypoplasia congenita (AHC) is a rare disorder that usually presents clinically as adrenal insufficiency in early infancy. It is caused by mutations in the NR0B1 gene which is located on the short arm of chromosome X (Xp21). The NR0B1 gene plays an important role in normal development and function of both the adrenal and gonadal axes and some patients with the disease can present in adolescence with hypogonadotropic hypogonadism. Testicular microlithiasis is an ultrasonographic finding of unknown etiology that has been associated with several benign conditions such as cryptorchidism, congenital adrenal hyperplasia, varicoceles, and testicular malignancy. We report the case of an 11-year-old boy who was diagnosed at the age of 8 months with X-linked AHC due to adrenal failure and presented testicular microlithiasis during follow-up. To the best of our knowledge, this is the first case of an X-linked AHC patient diagnosed with testicular microlithiasis in follow-up. PMID- 30286576 TI - Deepening Knowledge Through Basic and Clinical Research. PMID- 30286577 TI - Virtual Reality and Simulation for Progressive Treatments in Urology. AB - In urology technologies and surgical practices are constantly evolving and virtual reality (VR) simulation has become a significant supplement to existing urology methods in the training curricula of urologists. However, new developments in urology also require training and simulation for a wider application. In order to achieve this VR and simulation could play a central role. The purpose of this article is a review of the principal applications for VR and simulation in the field of urology education and to demonstrate the potential for the propagation of new progressive treatments. Two different cases are presented as examples: exposure therapy for paruresis and virtual cystoscopy for diagnosis and surgery of bladder cancer. The article uses research and publications listed in openly accessible directories and is organized into 3 sections: The first section covers features of VR and simulation technologies. The second one presents confirmed applications of current technologies in urology education and showcases example future applications in the domain of bladder treatment and surgery. The final section discusses the potential of the technology to improve health care quality. PMID- 30286578 TI - High Estradiol Differentially Affects the Expression of the Glucose Transporter Type 4 in Pelvic Floor Muscles of Rats. AB - PURPOSE: To characterize the relationship between serum estradiol levels and the expression of glucose transporter type 4 (Glut4) in the pubococcygeus and iliococcygeus muscles in female rats. METHODS: The muscles were excised from virgin rats during the metestrus and proestrus stages of the estrous cycle, and from sham and ovariectomized rats implanted with empty or estradiol benzoate filled capsules. The expression of estrogen receptors (ERs) was inspected in the muscles at metestrus and proestrus. Relative Glut4 expression, glycogen content, and serum glucose levels were measured. Appropriate statistical tests were done to identify significant differences (P<=0.05). RESULTS: The pubococcygeus and iliococcygeus muscles expressed ERalpha and ERbeta. Glut4 expression and glycogen content in the pubococcygeus muscle were higher at proestrus than at metestrus. No significant changes were observed in the iliococcygeus muscle. In ovariectomized rats, the administration of estradiol benzoate increased Glut4 expression and glycogen content in the pubococcygeus muscle alone. CONCLUSION: High serum estradiol levels increased Glut4 expression and glycogen content in the pubococcygeus muscle, but not in the iliococcygeus muscle. PMID- 30286579 TI - Neonatal Bladder Irritation Is Associated With Vanilloid Receptor TRPV1 Expression in Adult Rats. AB - PURPOSE: To evaluate whether mild chemical irritation of the bladder in neonatal rats is associated with persistent vanilloid receptor transient receptor potential vanilloid subfamily 1 (TRPV1) activity in adult rats. METHODS: Female Sprague-Dawley rats were used. Ten-day-old rat pups underwent bladder sensitization via intravesical infusion of 0.2% acetic acid in saline with or without prior bladder desensitization with capsaicin. After 8 weeks, 3 groups of rats (control [group 1], bladder sensitization [group 2], and bladder desensitization [group 3]) underwent cystometry. Inflammation of bladder tissue and the expression of TRPV1 in bladder tissue and dorsal root ganglia (DRG) were also evaluated. RESULTS: The bladder sensitization group showed more frequent voiding contractions. TRPV1 expression in adult bladder tissue was elevated in group 2. TRPV1 mRNA levels in the bladder and DRG were significantly higher in group 2 than in group 1. Moreover, group 2 had significantly more DRG neurons (identified by uptake of the retrograde label Fast Blue) that exhibited TRPV1 immunoreactivity. CONCLUSION: We found a significant association between neonatal bladder sensitization and persistent TRPV1 activity in adult rats. This is the first study to focus on the underlying pathogenesis of bladder overactivity from childhood to adulthood. Our findings could lead to the development of new strategies for the treatment and prevention of adult urinary symptoms arising from childhood urinary tract dysfunction. PMID- 30286580 TI - Treatment of Anterior Vaginal Wall Prolapse Using Transvaginal Anterior Mesh With Apical Fixation: A Prospective Multicenter Study With up to 2 Years of Follow-up. AB - PURPOSE: To evaluate the safety and efficacy of a surgical polypropylene mesh for correction of anterior vaginal prolapse, with or without apical defects, by providing simultaneous reinforcement at the anterior and apical aspects of the vagina with a single-incision approach. METHODS: This was a prospective, multicenter, single-arm study involving women with baseline stage >=2 anterior and/or apical vaginal wall prolapse according to the Pelvic Organ Prolapse Quantification (POP-Q) system. The primary endpoint was defined as achievement of POP-Q stage <=1 status. Additionally, patient-reported outcomes were assessed using the International Consultation on Incontinence Questionnaire-Vaginal Symptoms (ICIQ-VS). The device under evaluation was Calistar A, which is fixed posteriorly to the sacrospinous ligaments with a novel tissue-anchoring system (TAS) and anteriorly to the obturator internus muscles. Postoperative follow-ups were scheduled at 7 days and at 6, 12, and 24 months. RESULTS: Ninety-seven women were treated and assessed for the primary outcome. They were followed for up to 2 years (n=43), with a median of 12 months. Objective cure was achieved in 86 of the 97 patients (88.7%) (P<0.0005). The mean reduction in the ICIQ-VS scores was in the range of 70%-90% for every time point (P<0.05). No bleeding or surgical revision was reported. Mesh exposure occurred in 7 patients (7.2%), urinary retention in 5 (5.2%), de novo dyspareunia in 3 (3.1%), and urinary tract infections in 7 (7.2%). CONCLUSION: This midterm follow-up showed that apical and anterior vaginal reinforcement with a polypropylene implant fixed with a TAS provided good anatomical correction, with no major complications. PMID- 30286582 TI - Factors Influencing Lower Urinary Tract Symptoms in Advanced Cancer Patients With Chemotherapy-Induced Peripheral Neuropathy. AB - PURPOSE: This study aimed to investigate the severity of lower urinary tract symptoms (LUTS) and to identify factors that influenced LUTS in advanced cancer patients with chemotherapy-induced peripheral neuropathy (CIPN). METHODS: This cross-sectional study included a total of 158 advanced cancer patients with CIPN. A structured questionnaire including the International Prostate Symptom Score and the Functional Assessment of Cancer Therapy/Gynecology Oncology Group/Neurotoxicity scale was used. Data were analyzed using the Pearson correlation coefficient and multiple regression analysis. RESULTS: Nocturia was the most prevalent LUTS. A positive relationship was found between CIPN symptoms and LUTS. The duration of cancer diagnosis and the severity of CIPN were key factors that influenced LUTS. CONCLUSION: The severity of CIPN symptoms was the most important predictor of LUTS. Nurses' care for advanced cancer patients should incorporate a comprehensive health assessment, which includes a history of treatment and physical neuropathic symptoms, for any patient complaining of CIPN symptoms. PMID- 30286581 TI - Specificity of Lower Urinary Tract Symptoms in Neuromyelitis Optica in Comparison With Multiple Sclerosis Patients. AB - PURPOSE: The aim of this study was to describe lower urinary tract symptoms in neuromyelitis optica (NMO), and to compare these data with urinary disorders observed in multiple sclerosis (MS) patients. METHODS: Retrospective study of data collected from January 1997 to July 2017 using the database from a Neuro Urology Department of a university hospital. NMO and MS patients were matched for sex, age, and Expanded Disability Status Scale (EDSS). RESULTS: Twenty-six patients with NMO were included and compared with 33 MS patients. Mean age was 41.6 years (standard deviation [SD], 14,8), mostly female patients (24 vs. 2 males). Mean EDSS was 4.6 (SD, 1.8) in the 2 groups. In NMO group, 57% of the patients (n=15) had overactive bladder with urgency and urge incontinence and 38.5% (n=10) of them had nocturia. Voiding symptoms was observed in 69.2% of the patients (n=18); 42.3% of NMO patients performed self-intermittent catheterization versus 12.1% in MS patients (P=0.012). Low bladder compliance and severe urinary tract infections (pyelonephritis) were more frequent in NMO than in MS patients (respectively 15% vs. 0%, P=0.016 and 42% vs. 12%, P=0.024). CONCLUSION: Lower urinary tract symptoms, especially overactive bladder and urinary retention, are frequent in NMO. Low bladder compliance, serious urinary infections, and high prevalence of urinary retention requiring self-intermittent catheterization are the main symptoms significantly more frequent than in MS. PMID- 30286583 TI - Factors Associated With Early Recovery of Stress Urinary Incontinence Following Holmium Laser Enucleation of the Prostate in Patients With Benign Prostatic Enlargement. AB - PURPOSE: To investigate factors associated with early recovery of stress urinary incontinence (SUI) following holmium laser enucleation of the prostate (HoLEP) in patients with benign prostatic enlargement (BPE). METHODS: The medical records of 393 patients who underwent HoLEP for BPE were retrospectively reviewed. Patients with SUI following HoLEP were selected and divided into 2 groups: those who experienced early recovery of SUI and those who experienced persistent SUI. Recovery of SUI within 1 month after HoLEP was defined as early, and SUI that remained present after 1 month was defined as persistent. Preoperative clinical and urodynamic factors, as well as perioperative factors, were compared between groups. RESULTS: SUI following HoLEP was detected in 86 patients. Thirty-three patients exhibited recovery of SUI within 1 month, and SUI remained present in 53 patients after 1 month. Multivariate analysis showed that the transition zone prostate volume (odds ratio [OR], 5.354; 95% confidence interval [CI], 1.911 14.999; P=0.001) and the enucleation ratio (OR, 8.253; 95% CI, 1.786-38.126; P=0.007) were significantly associated with early recovery of SUI. CONCLUSION: Early recovery of SUI within 1 month following HoLEP was associated with transition zone prostate volume and the enucleation ratio. PMID- 30286584 TI - Predictors of Nerve Stimulator Success in Patients With Overactive Bladder. AB - PURPOSE: To identify factors associated with successful sacral nerve stimulator (SNS) trial after SNS implantation for the treatment of medication refractory overactive bladder (OAB). METHODS: Patients undergoing treatment for OAB at Lahey Hospital and Medical Center between 2004 and 2016 were identified. Patients undergoing SNS placement were identified; SNS success was defined as permanent implantation of the SNS. Demographic, clinical and treatment data were extracted from patient charts; uni- and multivariate analyses were conducted to identify factors associated with SNS treatment success. RESULTS: A total of 128 patients were included. On univariate analysis, male sex, prior diagnosis of benign prostatic hyperplasia, and lower volume at first urge on urodynamics (UDS) were associated with unsuccessful SNS trial. On multivariate analysis, male sex (odds ratio [OR], 0.145; 95% confidence interval [CI], 0.036-0.530) and lower volume at first urge on UDS (OR, 0.982; 95% CI, 0.967-0.995) were associated with unsuccessful SNS trial. A threshold value of 100 mL at first urge during preoperative UDS had a specificity of 0.86 in predicting SNS success in men. CONCLUSION: SNS is frequently successful at relieving OAB symptoms. Male patients and those with lower volumes at first urge on UDS, particularly below 100 mL, are more likely to have an unsuccessful SNS trial. Patients in these groups should be counseled on the lower likelihood of SNS success. PMID- 30286585 TI - Sex Differences in Lower Urinary Tract Symptoms in Older Korean Adults Living in Rural Areas: Prevalence, Quality of Life, and Associated Factors. AB - PURPOSE: Urinary incontinence (UI) is associated with nursing home admission, functional decline, and risk of death among community-dwelling older adults. Little information, however, is available on sex differences in lower urinary tract symptoms (LUTS) in older Korean adults exclusively living in rural areas. This study examined sex-related differences in LUTS, factors associated with UI in older adults living in rural areas, and health-related quality of life (HRQoL) in incontinent older adults. METHODS: This was a cross-sectional study in which face-to-face interviews were conducted at 15 rural community-health centres. A total of 323 older adults aged >=65 years from rural areas of Korea participated. LUTS prevalence was evaluated and HRQoL was measured using the King's Health Questionnaire. The chi-square test and t -test were used to examine sex differences in characteristics, LUTS, and HRQoL. Multivariable logistic regression was used to identify risk factors associated with UI. RESULTS: Nocturia was the most prevalent symptom, affecting 87% of men and 86% of women. Women (53%) had significantly more UI of any kind than did men (35%) (P=0.007). Urgency UI was the most frequent type of UI in men, whereas stress UI was the most frequent in women. Regarding HRQoL, men had significantly higher scores in the domains of sleep/energy disturbances (P=0.032) than did women, and women reported greater effects from the severity of incontinence (P=0.001) than did men. Arthritis was the only factor associated with UI in men (odds ratio [OR], 6.88; 95% confidence interval [CI], 1.46-32.36). However, women with diabetes mellitus were less likely to have UI than those without (OR, 0.43; 95% CI, 0.23 0.82). CONCLUSION: LUTS were found to be highly prevalent in community-dwelling older Korean adults in rural areas. Interventions to improve sleep and to reduce UI severity are needed for incontinent men and women, respectively. PMID- 30286587 TI - Reminiscing on 35 years with Environmental Toxicology in Korea.

PMID- 30286588 TI - Comparison of volatile organic compounds between cigarette smoke condensate (CSC) and extract (CSE) samples. AB - Cigarette smoke is a major risk factor for several diseases, including chronic obstructive pulmonary and cardiovascular diseases. The toxicity of the cigarette smoke can be determined in vitro. The cytotoxicity test of the cigarette smoke is commonly conducted using the cigarette smoke condensate (CSC) and cigarette smoke extract (CSE). The CSC and CSE methods are well known for sampling of the particles and water-soluble compounds in the cigarette smoke, respectively. In this study, the CSC and CSE were analyzed by using a gas chromatography-mass spectrometry (GC-MS) system equipped with a wax column for separation of the volatile organic compounds. The cytotoxic effect of the CSC and CSE were evaluated thoroughly by comparing the analytical results of the CSC and CSE samples. The total concentration of the volatile organic compounds detected in the CSC sample was similar to that in the CSE sample based on the peak area. Except for the dimethyl sulfoxide solvent, nicotine had the highest concentration in the CSC sample, while acetonitrile had the highest concentration in the CSE sample. The compositions were as follows: (1) CSC sample: 55.8% nicotine, 18.0% nicotyrine, 3.20% 1,2,3-propanetriol, triacetate, 1.28% ethyl chloride, 1.22% phenol, etc. and (2) CSE sample: 18.7% acetonitrile, 18.0% acetone, 12.5% 2 hydroxy-2-methyl-propanenitrile, 8.98% nicotine, 5.86% nicotyrine, etc. In this manner, to accurately examine the cytotoxicity of the cigarette smoke using CSC or CSE, the components and their concentrations in the CSC and CSE samples should be considered. PMID- 30286589 TI - Occurrence of microplastics in municipal sewage treatment plants: a review. AB - Municipal sewage treatment plants (STPs) are thought to be important point sources of microplastics in freshwater systems and many peer-reviewed articles have been published on this issue since mid-2010s. In this review, we summarize existing literature on the occurrence of microplastics in STPs and experimental methods used for isolation and identification of microplastics. The number concentrations of microplastics in STP influents were 15.1-640 L-1 , whereas those in the STP effluents were highly variable and ranged from not detectable to 65 L-1 . For most of cases, conventional STPs are removing microplastics very effectively. Fragments and fibers are dominant shapes of microplastics. Thermoplastics (polyethylene and polypropylene) and polyester are the predominant materials recovered. Although further research is needed, size distribution of microplastics in STPs is likely to follow a power law, implying that different studies using different size cutoffs may be compared after establishing a power law relationship. PMID- 30286590 TI - A review of current studies on cellular and molecular mechanisms underlying pulmonary fibrosis induced by chemicals. AB - Several studies showed that the inflammatory and fibrotic responses induced by polyhexamethylene guanidine phosphate (PHMG-p) were similar to those observed for idiopathic pulmonary fibrosis in South Korea in 2011. "Omic" technologies can be used to understand the mechanisms underlying chemical-induced diseases. Studies to determine the toxicity of chemicals may facilitate understanding of the mechanisms underlying the development of pulmonary fibrosis at a molecular level; thus, such studies may provide information about the toxic characteristics of various substances. In this review, we have outlined the cellular and molecular mechanisms underlying idiopathic pulmonary fibrosis and described pulmonary fibrosis induced by various chemicals, including bleomycin, paraquat, and PHMG-p, based on the results of studies performed to date. PMID- 30286592 TI - Ginkgo biloba extract (EGb761) did not express estrogenic activity in an immature rat uterotrophic assay. AB - Ginkgo biloba is a dioecious tree that has been used in traditional Chinese medicine for about 5,000 years. In previous studies on ginkgo biloba extract (EGb761) using in vitro systems, we confirmed that EGb761 has biphasic effects on estrogenicity. In this study, we evaluated the agonistic and antagonistic activities of EGb761 using a uterotrophic assay in immature female rats. To evaluate agonistic and antagonistic effects of EGb761 on uterus, 21-day-old immature Sprague-Dawley (SD) female rats were treated with EGb761 (100, 200, or 400 mg/kg) by oral gavage, 10 MUg/kg of estradiol (E2) or 1 mg/kg tamoxifen (TM) by subcutaneous injection, or with EGb761 plus E2 or TM for 3 consecutive days. At the end of the treatment period, animals were sacrificed and their body weights and organ weights (liver, lung, spleen and kidney) were measured. In addition, estrogen-related gene expressions (IGFBP-1 in liver and CaBP-9 in uterus) were determined. During the experiment, no animal showed clinical signs, a change in body weight or died. EGb761 treatment alone had no effect on absolute/relative uterine weight, luminal epithelial cell height (LECH, MUm), or luminal circumference (LC, MUm). In addition, uterine weights, LECHs, and LC induced by E2 or TM were not significantly changed by EGb761 at any dose. These results collectively suggested EGb761 has no agonistic/antagonistic effects in utero. PMID- 30286591 TI - Epigenetic profiling to environmental stressors in model and non-model organisms: Ecotoxicology perspective. AB - Epigenetics, potentially heritable changes in genome function that occur without alterations to DNA sequence, is an important but understudied component of ecotoxicology studies. A wide spectrum of environmental challenge, such as temperature, stress, diet, toxic chemicals, are known to impact on epigenetic regulatory mechanisms. Although the role of epigenetic factors in certain biological processes, such as tumourigenesis, has been heavily investigated, in ecotoxicology field, epigenetics still have attracted little attention. In ecotoxicology, potential role of epigenetics in multi- and transgenerational phenomenon to environmental stressors needs to be unrevealed. Natural variation in the epigenetic profiles of species in responses to environmental stressors, nature of dose-response relationships for epigenetic effects, and how to incorporate this information into ecological risk assessment should also require attentions. In this review, we presented the available information on epigenetics in ecotoxicological context. For this, we have conducted a systemic review on epigenetic profiling in response to environmental stressors, mostly chemical exposure, in model organisms, as well as, in ecotoxicologically relevant wildlife species. PMID- 30286593 TI - What Explains Socioeconomic Inequality in Health-related Quality of Life in Iran? A Blinder-Oaxaca Decomposition. AB - OBJECTIVES: This study aimed to explain the health-related quality of life (HRQoL) gap between the poorest and the wealthiest quintiles in the capitals of Kermanshah and Kurdistan Provinces (Kermanshah and Sanandaj), in western Iran. METHODS: This was a cross-sectional study conducted among 1772 adults. Data on socio-demographic characteristics, socioeconomic status (SES), lifestyle factors, body mass index, and HRQoL of participants were collected using a self administered questionnaire. The slope and relative indices of inequality (SII and RII, respectively) were employed to examine socioeconomic inequality in poor HRQoL. Blinder-Oaxaca (BO) decomposition was used to quantify the contribution of explanatory variables to the gap in the prevalence of poor HRQoL between the wealthiest and the poorest groups. RESULTS: The overall crude and age-adjusted prevalence of poor HRQoL among adults was 32.0 and 41.8%, respectively. The SII and RII indicated that poor HRQoL was mainly concentrated among individuals with lower SES. The absolute difference (%) in the prevalence of poor HRQoL between the highest and lowest SES groups was 28.4. The BO results indicated that 49.9% of the difference was explained by different distributions of age, smoking behavior, physical inactivity, chronic health conditions, and obesity between the highest and lowest SES groups, while the remaining half of the gap was explained by the response effect. CONCLUSIONS: We observed a pro-rich distribution of poor HRQoL among adults in the capitals of Kermanshah and Kurdistan Provinces. Policies and strategies aimed at preventing and reducing smoking, physical inactivity, chronic health conditions, and obesity among the poor may reduce the gap in poor HRQoL between the highest and lowest SES groups in Iran. PMID- 30286594 TI - Increased Prevalence of Chronic Disease in Back Pain Patients Living in Car dependent Neighbourhoods in Canada: A Cross-sectional Analysis. AB - OBJECTIVES: Chronic diseases, including back pain, result in significant patient morbidity and societal burden. Overall improvement in physical fitness is recommended for prevention and treatment. Walking is a convenient modality for achieving initial gains. Our objective was to determine whether neighbourhood walkability, acting as a surrogate measure of physical fitness, was associated with the presence of chronic disease. METHODS: We conducted a cross-sectional study of prospectively collected data from a prior randomized cohort study of 227 patients referred for tertiary assessment of chronic back pain in Ottawa, ON, Canada. The Charlson Comorbidity Index (CCI) was calculated from patient completed questionnaires and medical record review. Using patients' postal codes, neighbourhood walkability was determined using the Walk Score, which awards points based on the distance to the closest amenities, yielding a score from 0 to 100 (0- 50: car-dependent; 50-100: walkable). RESULTS: Based on the Walk Score, 134 patients lived in car-dependent neighborhoods and 93 lived in walkable neighborhoods. A multivariate logistic regression model, adjusted for age, gender, rural postal code, body mass index, smoking, median household income, percent employment, pain, and disability, demonstrated an adjusted odds ratio of 2.75 (95% confidence interval, 1.16 to 6.53) times higher prevalence for having a chronic disease for patients living in a car-dependent neighborhood. There was also a significant dose-related association (p=0.01; Mantel-Haenszel chi square=6.4) between living in car-dependent neighbourhoods and more severe CCI scores. CONCLUSIONS: Our findings suggest that advocating for improved neighbourhood planning to permit greater walkability may help offset the burden of chronic disease. PMID- 30286596 TI - Demographic and Survivorship Disparities in Non-muscle-invasive Bladder Cancer in the United States. AB - OBJECTIVES: To examine survivorship disparities in demographic factors and risk status for non-muscle-invasive bladder cancer (NMIBC), which accounts for more than 75% of all urinary bladder cancers, but is highly curable with early identification and treatment. METHODS: We used the US National Cancer Institute's Surveillance, Epidemiology, and End Results registries over a 19-year period (1988-2006) to examine survivorship disparities in age, sex, race/ethnicity, and marital status of patients and risk status classified by histologic grade, stage, size of tumor, and number of multiple primary tumors among NMIBC patients (n=29 326). We applied Kaplan-Meier (K-M) and Cox proportional hazard methods for survival analysis. RESULTS: Among all urinary bladder cancer patients, the majority of NMIBCs were in male (74.1%), non-Latino white (86.7%), married (67.8%), and low-risk (37.6%) to intermediate-risk (44.8%) patients. The mean age was 68 years. Survivorship (in median life years) was highest for non-Latino white (5.4 years), married (5.4 years), and low-risk (5.7 years) patients (K-M analysis, p<0.001). We found significantly lower survivorship for elderly, male (female hazard ratio [HR], 0.96), Latino (HR, 1.20), and unmarried (married HR, 0.93) patients. CONCLUSIONS: Survivorship disparities were ubiquitous across age, sex, race/ethnicity, and marital status groups. Non-white, unmarried, and elderly patients had significantly shorter survivorship. The implications of these findings include the need for a heightened focus on health policy and more organized efforts to improve access to care in order to increase the chances of survival for all patients. PMID- 30286595 TI - The Role of Social Support and the Neighborhood Environment on Physical Activity in Low-income, Mexican-American Women in South Texas. AB - OBJECTIVES: To determine the relationships between physical activity (PA), the neighborhood environment support for PA, and social support for PA among Mexican American women living in South Texas. The Enlace study was a randomized controlled trial that tested the effectiveness of a promotora-led PA intervention among low-income Mexican origin women (n=614) living in colonias. METHODS: The dependent measures included accelerometer-measured average moderate to vigorous physical activity (MVPA) and sedentary breaks and the Community Health Activities Model Program for Seniors PA 41-item questionnaire. The independent measures included the Physical Activity and Neighborhood Environment Scale (PANES) and the 13-item Physical Activity Social Support (PASS) scale. RESULTS: Enlace participants were on average 40.4 (standard deviation, 10.3) years old, born in Mexico (86.1%), and uninsured (83.1%). Adjusted linear regression results indicated that each 1-point increment in the PANES overall score was associated with 0.050 (p<0.001) unit increase in sedentary break and a -0.043 (p=0.001) unit decrease in sedentary break duration. Both PANES (beta=0.296; p=0.002) and PASS scores (beta=0.076; p<0.001) were associated with weekly average self-reported MVPA. Interaction effects were observed between PASS scores and accelerometer measured frequency of sedentary breaks and sedentary time duration. CONCLUSIONS: The findings of this study indicate that the relationships between PA and built environment and social support are measure-dependent and suggest that reducing sedentary time in this population may require a closer assessment of social support for PA. PMID- 30286597 TI - Effect of Uric Acid on the Development of Chronic Kidney Disease: The Korean Multi-Rural Communities Cohort Study. AB - OBJECTIVES: Several studies have investigated the effects of serum uric acid (SUA) levels on chronic kidney disease (CKD), with discrepant results. The effect of SUA levels on CKD development was studied in the Korean rural population. METHODS: A total of 9695 participants aged >=40 years were recruited from 3 rural communities in Korea between 2005 and 2009. Of those participants, 5577 who participated in the follow-up and did not have cerebrovascular disease, myocardial infarction, cancer, or CKD at baseline were studied. The participants, of whom 2133 were men and 3444 were women, were grouped into 5 categories according to their quintile of SUA levels. An estimated glomerular filtration rate of <60 mL/min/1.73 m2 at the time of follow-up was considered to indicate newly developed CKD. The effects of SUA levels on CKD development after adjusting for potential confounders were assessed using Cox proportional hazard models. RESULTS: Among the 5577 participants, 9.4 and 11.0% of men and women developed CKD. The hazard ratio (HR) of CKD was higher in the highest quintile of SUA levels than in the third quintile in men (adjusted HR, 1.60; 95% confidence interval [CI], 1.02 to 2.51) and women (adjusted HR, 1.56; 95% CI, 1.14 to 2.15). Furthermore, CKD development was also more common in the lowest quintile of SUA levels than in the third quintile in men (adjusted HR, 1.83; 95% CI, 1.15 to 2.90). The effect of SUA was consistent in younger, obese, and hypertensive men. CONCLUSIONS: Both high and low SUA levels were risk factors for CKD development in rural Korean men, while only high levels were a risk factor in their women counterparts. PMID- 30286599 TI - Necessity of Epigenetic Epidemiology Studies on the Carcinogenesis of Lung Cancer in Never Smokers. AB - Based on epidemiological and genomic characteristics, lung cancer in never smokers (LCNS) is a different disease from lung cancer in smokers. Based on current research, the main risk factor for LCNS may be air pollution. A recent case-control study in Koreans reported that nitrogen dioxide (NO2) may be a risk factor for LCNS. Additionally, a cohort study showed that exposure to NO2 was associated with significant hypomethylation. Thus, epigenetic epidemiology studies are needed in the near future to evaluate the carcinogenesis of LCNS according to chronic exposure to air pollution and/or viral infections. PMID- 30286598 TI - National Trends in Smoking Cessation Medication Prescriptions for Smokers With Chronic Obstructive Pulmonary Disease in the United States, 2007-2012. AB - OBJECTIVES: Smoking cessation decreases morbidity and mortality due to chronic obstructive pulmonary disease (COPD). Pharmacotherapy for smoking cessation is highly effective. However, the optimal prescription rate of smoking cessation medications among smokers with COPD has not been systemically studied. The purpose of this study was to estimate the national prescription rates of smoking cessation medications among smokers with COPD and to examine any disparities therein. METHODS: We conducted a retrospective study using National Ambulatory Medical Care Survey data from 2007 to 2012. We estimated the national prescription rate for any smoking cessation medication (varenicline, bupropion, and nicotine replacement therapy) each year. Multiple survey logistic regression was performed to characterize the effects of demographic variables and comorbidities on prescriptions. RESULTS: The average prescription rate of any smoking cessation medication over 5 years was 3.64%. The prescription rate declined each year, except for a slight increase in 2012: 9.91% in 2007, 4.47% in 2008, 2.42% in 2009, 1.88% in 2010, 1.46% in 2011, and 3.67% in 2012. Hispanic race and depression were associated with higher prescription rates (odds ratio [OR], 5.15; 95% confidence interval [CI], 1.59 to 16.67 and OR, 2.64; 95% CI, 1.26 to 5.51, respectively). There were no significant differences according to insurance, location of the physician, or other comorbidities. The high OR among Hispanic population and those with depression was driven by the high prescription rate of bupropion. CONCLUSIONS: The prescription rate of smoking cessation medications among smokers with COPD remained low throughout the study period. Further studies are necessary to identify barriers and to develop strategies to overcome them. PMID- 30286600 TI - Molecular Insights into the Unusual Structure of an Antifreeze Protein with a Hydrated Core. AB - The primary driving force for protein folding is the formation of a well-packed, anhydrous core. However, recently, the crystal structure of an antifreeze protein, maxi, has been resolved where the core of the protein is filled with water, which apparently contradicts the existing notion of protein folding. Here, we have performed standard molecular dynamics (MD) simulation, replica exchange MD (REMD) simulation, and umbrella sampling using TIP4P water at various temperatures (300, 260, and 240 K) to explore the origin of this unusual structural feature. It is evident from standard MD and REMD simulations that the protein is found to be stable at 240 K in its unusual state. The core of protein has two layers of semi-clathrate water separating the methyl groups of alanine residues from different helical strands. However, with increasing temperature (260 and 300 K), the stability decreases as the core becomes dehydrated, and methyl groups of alanine are tightly packed driven by hydrophobic interactions. Calculation of the potential of mean force by an umbrella sampling technique between a pair of model hydrophobes resembling maxi protein at 240 K shows the stabilization of second solvent-separated minima (SSM), which provides a thermodynamic rationale of the unusual structural feature in terms of weakening of the hydrophobic interaction. Because the stabilization of SSMs is implicated for cold denaturation, it suggests that the maxi protein is so designed by nature where the cold denatured-like state becomes the biologically active form as it works near or below the freezing point of water. PMID- 30286601 TI - Finding Free-Energy Landmarks of Chemical Reactions. AB - We propose a novel approach to search for free-energy landmarks, i.e., minima and the saddle points, of chemical reactions in an automated manner using a combination of steepest descent and gentlest ascent methods. A numerical approach is suggested to improve the sampling efficiency of the second derivatives of the free-energy surface, which is required in the gentlest ascent method. This technique opens a way to identify free-energy landmarks of bond-breaking/creating processes in which the underlying potential energy surface is described using on the-fly electronic structure calculations. As demonstrations of the approach, we present applications to the ring-opening of cis-1,2-dimethylbenzocyclobutene using the semiempirical PM7 method, focusing on the temperature dependence of the paths and barrier of the reaction, and we study an SN2 reaction in aqueous solution using a semiempirical QM/MM approach combining PM7 with the TIP3P water model. PMID- 30286602 TI - A Simple Phase Correction Makes a Big Difference in Nonadiabatic Molecular Dynamics. AB - The outcomes of nonadiabatic molecular dynamics (NA-MD) calculations are modulated by the parameters entering the time-dependent Schrodinger equation (TD SE). The adiabatic states are commonly used as the basis in which the TD-SE is integrated. However, the phase inconsistencies of such states along the nuclear trajectories obtained in NA-MD simulations may render the wave function and other relevant properties ill-behaving, adversely affecting the dynamics. This work illustrates the consequence of adiabatic state phase inconsistencies in nonadiabatic Ehrenfest dynamics. A simple phase-correction approach is proposed and is demonstrated to alter the dynamics to make it consistent with the reference calculations done in the phase-consistent diabatic representation.

PMID- 30286603 TI - Aristolochic Acids as Persistent Soil Pollutants: Determination of Risk for Human Exposure and Nephropathy from Plant Uptake. AB - Exposure to aristolochic acids (AAs) from Aristolochia plants is one of the major global causes of nephropathy, including Balkan endemic nephropathy (BEN); renal failure; and urothelial cancer. The high incidence of BEN on the Balkan Peninsula is assumed to result from consumption of Aristolochia clematitis L. seeds coharvested with crops. Here, we show that AAs are long-lived soil contaminants that enter wheat and maize plants by root uptake with strong pH dependence. Soil and crops from Serbian farms in areas endemic for A. clematitis were found to be extensively contaminated with AAs, with contamination strongly correlated with local incidence of BEN. The persistence of AAs as soil contaminants suggests that weed control for A. clematitis plants is needed to reduce the incidence of BEN and aristolochic acid nephropathy, systematic surveys of soil and crop AA levels would identify high-risk regions, and it is imperative to research soil remediation methods.

AB - We present the case of a patient with obstructive jaundice due to a polylobulated lesion at the middle common bile duct that is identified as a villous adenoma of the main bile duct. This entity is infrequent with few references in the bibliography. It is a benign pathology but with risk of malignancy, so the diagnosis and resection is essential for adequate treatment. PMID- 30286606 TI - Evaluating the role of mindfulness in terms of asthma-related outcomes and depression and anxiety symptoms among individuals with asthma. AB - The aim of the current study was to examine the unique role of mindfulness skills in terms of: (1) asthma-related outcomes (i.e., asthma control, asthma quality of life); (2) depression symptoms; and (3) anxiety symptomatology (i.e., anxiety sensitivity, panic symptoms, global anxiety) among non-smoking adults with current asthma. Participants were 61 (61.9% female; Mage = 34.72 years, SD = 13.58, range = 18-65) non-smoking adults with current asthma who completed a battery of self-report measures. Results indicated that, after controlling for the effects of race and age, greater ability to describe present moment experiences was significantly associated with better asthma-related quality of life and lower levels of anxiety symptoms. Though mindfulness skills together were associated with lower levels of panic symptoms, there were no significant individual associations between specific skills and panic symptoms. Greater nonjudgment of present moment experiences was associated with lower levels of anxiety and anxiety sensitivity. Greater nonreactivity was significantly associated with lower levels of depression symptoms and anxiety sensitivity. Lastly, a greater ability to observe present moment experiences was associated with lower levels of anxiety sensitivity. Mindfulness was not significantly associated with asthma control. These findings suggest that it may be useful to target the mindfulness skills of describing, nonjudgment, and nonreactivity among individuals with asthma, particularly those with elevated levels of anxiety and depression, in order to improve psychological and asthma-related outcomes. PMID- 30286607 TI - Morphological and functional features prognostic factor of magnetic resonance imaging in locally advanced rectal cancer. AB - Background Although imaging can be suggestive of the diagnosis of rectal cancer, the primary imaging role is to assist in treatment triage of histologically diagnosed tumors. The possibility of a multimodal approach in the response to the treatment opens the way for the selection of criteria more personalized to the patient. Purpose To assess the prognostic factor of morphological and functional magnetic resonance imaging (MRI) in rectal cancer. Material and Methods Seventy seven patients were enrolled and underwent MRI before treatment and 59 patients underwent MRI after treatment. Radiologists evaluated the presence of lesions using a 4-point confidence scale; they recorded anatomical side, extent, and distance from the anorectal junction and distance from the circumferential margin. Tumor location was classified according to the involvement of proximal rectal channel and/or distal rectal channel. Radiologists scored signal intensity on T2-weighted (T2W) images, diffusion-weighted images (DWI), and MRI dynamic enhancement pattern. Tumor regression grade (TRG) and pathological T (pT) were the gold standard. Results Lesion vascularization score before treatment showed a predictive value of complete pathological response (sensitivity 88%, specificity 50%) based on pT, while using TRG lymph node number before treatment (sensitivity 83%, specificity 57%) showed a predictive value for response treatment. T2W signal (sensitivity 78%, specificity 30%) and DWI signal after treatment (sensitivity 78%, specificity 61%) showed a good predictive value for local rectal recurrences. Conclusions Lesion vascularization and lymph node number had a predictive value for neoadjuvant treatment complete response in rectal cancer. T2W signal intensity and DWI signal showed a good predictive value for local rectal recurrences. PMID- 30286609 TI - The prevalence of depression and insomnia symptoms among patients with rheumatoid arthritis and osteoarthritis in Poland: a case control study. AB - The objective of the study was to assess the prevalence of symptoms of depression and insomnia among patients with rheumatoid arthritis and osteoarthritis in comparison with individuals without chronic diseases. The study was carried out at National Institute of Geriatrics, Rheumatology and Rehabilitation, included 229 persons. The participants were divided into the following groups: group I - 120 patients with rheumatoid arthritis, group II - 58 patients with osteoarthritis, group III - 51 healthy individuals no confirmed depression (control group). Symptoms of depression were confirmed by a multiple-choice self reported Beck Depression Inventory questionnaire. Symptoms of depression confirmed with depression inventory>= 10 occurred as follows: patients with rheumatoid arthritis - 75.83%, patients with osteoarthritis - 50%, control group 23.53% (p<0.0001), with the prevalence of insomnia (AIS>=6) at: 71%, 32% and 33%, respectively (p<0.001). In group I mean values of FIRST and AIS were 23.06 and 8.36 respectively, with group II: 21.71 and 7.84, respectively. In all subjects with AIS>=6, the depression inventory was statistically significantly (p<0.005) higher than in the subjects with AIS<6 (respectively: 17.02 vs 12.13; 15.6 vs 8.05; 5.45 vs 1.81). Patients with rheumatoid arthritis find it difficult to cope with stress. Insomnia as a reaction to stress occurs more often in this group. PMID- 30286608 TI - Spatial dynamics and epidemiology for AIDS in remote areas in French Guiana. AB - Although AIDS care is generally improving in French Guiana, disparities among regions and certain key populations remain significant. The purpose of this study was to describe the spatial and clinical characteristics of people living with HIV (PLHIV) in remote areas in comparison to those followed in hospitals on the urban coast of French Guiana. The data presented were obtained from outpatient on primary care centers located in rural regions away from the urban coast. Data were compared with that from medical records of PLHIV treated in French Guiana's urban care. The evolution of the annual rate of discovery of HIV seropositivity indicates a lag in remote areas as compared to urban and coastal areas. In recent years, the epidemic appeared as particularly active in rural areas among Brazilian patients. The median age of PLHIV in remote areas was 43.8 years, the sex ratio (M/F) was 0.93. Nearly 37% of PLHIV were discovered with advanced disease (<200 CD4/mm3). The percentage of virological success after six months of HAART was 80% and 88% in remote areas and urban area, respectively. Efforts must be made to control and halt the spread of the HIV epidemic, as these remote sites represent strategic points. PMID- 30286610 TI - Retaining identity: Creativity and caregiving. AB - Arts programming for people living with dementia and their caregivers has gained popularity as a way to provide opportunities for social interaction, expression, and continual learning. The goal of the present study, referred to as Retaining Identity: Creativity & Caregiving is to: (1) describe the process of designing and implementing a structured art experience for people living with memory loss and their co-residing caregiver; and (2) to summarize feedback provided by caregivers at the conclusion of the program. Retaining Identity is an eight-week program offered by professional artists who instructed dementia caregivers in four visual art activities, which they then taught to their care recipient. The program was designed for individuals with no art experience and the art projects were carefully developed to be engaging for both people living with dementia and their caregivers. The evaluation process included a qualitative survey completed by the caregivers to measure the impact of the program on the caregiver/care recipient relationship. The main themes that emerged from the survey were: caregiver growth, caregiver awareness, and creative discovery. The participants' artwork supports that art making has the potential to encourage an equitable exchange and outcome for people with memory loss and their caregivers. Although the survey is limited in scope, the results support the use of the arts to positively impact caregivers and their relationship with their care recipient. PMID- 30286612 TI - Evaluation of a Pharmacy-to-Dose Pneumococcal Vaccination Protocol at an Academic Medical Center. AB - BACKGROUND: In February 2016, a pharmacy-to-dose (PTD) pneumococcal vaccination protocol was implemented to aid in the appropriate selection of pneumococcal vaccines. OBJECTIVE: The primary objective was to compare the rate of appropriate vaccine ordering with the PTD protocol. Secondary objectives were to assess vaccine administration rate and determine factors preventing patients from receiving the vaccine after appropriate selection. METHODS: This was a single center, retrospective cohort study of adult patients admitted to an inpatient service. Eligible patients were 19 years of age or older and had either a PTD pneumococcal vaccination order placed or an alert triggered indicating that the patient was a candidate for a vaccination. Patients were excluded if they had contraindications to receiving either pneumococcal vaccine. The Fisher exact test was used to evaluate the primary objective, and descriptive statistics were used to evaluate the secondary objectives. RESULTS: A total of 327 patients were included in the analysis: 167 in the preprotocol cohort and 160 in the postprotocol cohort. The correct vaccine ordering rates were found to be 26.9% (45/167) and 83.1% (133/160) in the preprotocol and postprotocol cohorts, respectively ( P < 0.001). In the postprotocol cohort, 17.5% (28/160) of patients did not have a vaccine administered. Reasons for vaccine administration failure were identified as patient refusal, patient expired during admission, vaccine not dispensed by pharmacy, and vaccine dispensed by pharmacy but returned. CONCLUSIONS: The PTD pneumococcal vaccination protocol significantly improved correct vaccine ordering rates. PMID- 30286611 TI - Acupuncture for Cancer Pain and Symptom Management in a Palliative Medicine Clinic. AB - OBJECTIVE: Studies suggest acupuncture improves cancer-related symptoms; however, it is unclear whether patient characteristics predict pain response. This study determined acupuncture's effect on cancer-related pain and identified variables associated with pain response. METHODS: A retrospective chart review included adult patients with cancer referred to palliative medicine and received acupuncture for pain management. Paired t tests compared differences in pain scores from pre- to postacupuncture. Clinically meaningful pain improvement was defined as >=2-point reduction in pain score. Logistic regression was used to evaluate associations between patient characteristics and pain improvement. RESULTS: One hundred seventy acupuncture treatments from 68 individual patients were studied. Significant reductions in mean pain scores were observed after the first treatment (-1.9 +/- 1.8; P < .001) and across all treatments (-1.7 +/- 1.9; P < .001). Multivariable analysis demonstrated clinically meaningful pain improvement with higher baseline pain scores (odds ratio [OR]: 1.79, 95% confidence interval [CI]: 1.44-2.22; P < .001) and stage III/IV disease (OR: 3.23, 95% CI: 1.11-9.40; P < .001). There were significant improvements in anxiety, depression, drowsiness, dyspnea, fatigue, nausea, and well-being after the first treatment and across all treatments ( P < .001). CONCLUSIONS: Acupuncture improved cancer-related pain and other symptoms. Those with higher baseline pain scores and advanced disease were more likely to achieve significant pain reduction. Improved depression and fatigue were closely related to pain reduction. Further studies are needed to confirm pain response variables, establish durability, and develop a personalized approach to acupuncture. PMID- 30286613 TI - The Effectiveness of Reality Orientation Therapy in the Treatment of Parkinson Disease Dementia. AB - Patients with Parkinson disease dementia (PDD) have deficits resulting mainly from frontostriatal dysfunction. The aim of this study was to assess the effectiveness of reality orientation therapy (ROT) combined with drug therapy (acetylcholinesterase inhibitors) in PDD treatment and compare it with that of drug therapy alone. Patients (n = 12) with a diagnosis of PDD were divided into 2 groups: group A-drug therapy and ROT; group B-drug therapy alone. Reality orientation therapy was applied weekly for 6 months, and patients were assessed during the same period. Significant improvements in frontostriatal deficits were observed in the group that received the combined therapy, as shown mainly by the scores in verbal fluency in the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) battery ( P = .02) and in attention in Scales for outcomes of Parkinson's Disease-Cognition ( P = .021) and Clock Drawing Test ( P = .037). Patients who received only medication had worse results in constructional praxis recall in the CERAD battery ( P = .037). Our results indicate that ROT may help in the treatment of frontostriatal cognitive deficits and can potentially be used to complement drug therapy. PMID- 30286614 TI - Regulatory Requirements and Innovation: A Comparison of the Dermatologic Antifungal Drug Product Markets in Brazil and United States. AB - BACKGROUND: Development of novel dermatological topical products for the treatment of cutaneous fungal infections is a constant necessity, especially in developing countries. Through public health policies, many developing countries have facilitated in the last decades the entry of generic products, which can be superficially seen as a threat to innovation. To verify whether regulatory requirements, or the waiving of some requirements, could have an impact on innovation, we performed a detailed technical comparison of the dermatologic antifungal markets of Brazil and of the United States, taking Brazil as an example of a developing country with more lenient requirements regarding the registration of generic topical drug products. METHODS: The official databank of ANVISA (DATAVISA) and of US Food and Drug Administration (Orange Book) were assessed for valid topical dermatological antifungal drug products registered. RESULTS: The Brazilian market has a greater number of registered drug products encompassing a greater variety of drug substances than the US, but the latter comprises more products with novel technologies. In both countries, cream was the predominant dosage form and imidazoles were the major substance group. Ketoconazole was the lead active substance in Brazil and ciclopirox was the lead drug in the US. Generic products dominated both markets. CONCLUSIONS: Despite the great number of registered products, the Brazilian market lacks the latest technologies, reflecting that the ease of generics registration is not accompanied by innovation. PMID- 30286615 TI - Clinical Research Coordinators' Attitude Toward Risk-Based Monitoring. AB - BACKGROUND: Clinical research coordinators (CRCs) are persons who collect, record, and maintain clinical trial data in accordance with the principles of Good Clinical Practice at investigators' sites. This study was conducted to examine attitudes of clinical research coordinators (CRCs) toward risk-based monitoring (RBM) prior to full-scale implementation of RBM in Korea. METHODS: The study subjects were 607 CRCs, and data were collected using a self-reported questionnaire. Collected data were analyzed by frequency, percentage, chi2 test and Fisher exact test. RESULTS: Among CRCs, 42.3% had heard of RBM and 44.6% were found to oppose its implementation. Those opposed believed that implementation of RBM would increase the workload of CRCs and CRAs' work support for CRCs. In addition, they showed many negative opinions such as poor accuracy of test data input and failure to increase the overall quality of clinical tests. In particular, such attitudes were more noticeable in CRCs with 5 or more years of experience. CONCLUSION: Before the implementation of RBM, it is necessary to come up with administrative measures such as education for practitioners and recruitment of human resources to help CRCs properly understand RBM. PMID- 30286616 TI - Sustained exposure to acute migraine medications combined with repeated noxious stimulation dysregulates descending pain modulatory circuits: Relevance to medication overuse headache. AB - Background Loss of conditioned pain modulation/diffuse noxious inhibitory controls has been demonstrated in patients with migraine and medication overuse headache. We hypothesized that exposure to acute migraine medications may lead to dysregulation of central pain modulatory circuits that could be revealed by evaluating diffuse noxious inhibitory controls and that prior noxious stimulus is required for a loss of the diffuse noxious inhibitory control response in rats exposed to these medications. Methods Rats were "primed" by continuous infusion of morphine or one of two doses of sumatriptan. Diffuse noxious inhibitory control was evaluated at the end of drug-priming (day 7) and again after sensory thresholds returned to baseline (day 21). The Randall-Selitto hindpaw pressure test was used as the test stimulus and forepaw capsaicin injection served as the conditioning stimulus. Results Morphine-primed rats showed opioid-induced hyperalgesia accompanied by a loss of diffuse noxious inhibitory controls on day 7. Sumatriptan-primed rats did not develop hyperalgesia or loss of diffuse noxious inhibitory controls on day 7. Morphine-primed and high-dose sumatriptan primed rats only had a loss of diffuse noxious inhibitory control on day 21 if they received a capsaicin injection on day 7. Conclusions Prolonged exposure to migraine treatments followed by an acute nociceptive stimulation caused long lasting alterations in descending pain modulation, shown by a loss of diffuse noxious inhibitory controls. Morphine was more detrimental than sumatriptan, consistent with clinical observations of higher medication overuse headache risk with opioids. These data suggest a mechanism of medication overuse headache by which migraine medications combined with repeated episodes of pain may amplify the consequences of nociceptor activation and increase the probability of future migraine attacks as well as risk of medication overuse headache. PMID- 30286617 TI - Performance evaluation of the GastroPlusTM software tool for prediction of the toxicokinetic parameters of chemicals. AB - The accurate prediction of toxicokinetic parameters arising from oral, dermal and inhalation routes of chemical exposure is a key element in chemical safety assessments. In this research, the physiologically based pharmacokinetic (PBPK) GastroPlusTM software was evaluated against a series of chemicals for the prediction of toxicokinetic parameters. Overall, 67% of predicted intrinsic clearance (Clint) values were within 1- to 10-fold of empirical data for 463 compounds, and 87% of the predicted fraction unbounded in plasma (Fup) values were 1- to 3-fold of empirical data for 441 compounds. The r2 (coefficient of determination) of predicted Cmax (maximum plasma concentration) and AUC (Area Under Curve) values versus the corresponding empirical values from oral, inhalation and dermal exposures ranged from 0.04 to 0.92. Among the three exposures, the highest r2 values, ranging from 0.80 to 0.92, were observed for oral exposure predictions, where 88% of the compounds had 1- to 10-fold differences between predicted and empirical values for Cmax and AUC. The predicted plasma Css (steady-state plasma concentration) values were consistent with those Css values calculated by in vitro-to-in vivo extrapolation (IVIVE) approaches using experimental parameters. Based on the evaluation results, GastroPlusTM can be used as a QSAR/PBPK tool for toxicokinetic parameter predictions.

AB - BACKGROUND: The Pharmaceutical Medicine program at the University of New South Wales provides postgraduate education for students seeking employment relating to development of new medicines and medical technology. The objective of this study was to determine which changes to the program were required to meet future educational needs of students. METHODS: Responses to questions from 76 students, tutors, lecturers, and stakeholders were obtained via Qualtrics surveys. RESULTS: Most respondents would recommend the program because of scope and program emphasis, content, quality of teaching, flexibility, and availability of distance and online content. Students valued links to industry and the national regulatory authority. Respondents recommended program content be current, expanded to meet needs of the Asia-Pacific region, and structured to ensure opportunities for networking and collaboration. CONCLUSIONS: Recommended changes to the program are being implemented to optimize skills and knowledge of graduates for roles in global pharmaceutical, medical technology, and biotechnology industries.

AB - INTRODUCTION: Blood glucose monitoring systems (BGMS) should provide sufficient analytical quality to allow adequate therapy for diabetes patients. Besides system accuracy, measurement precision is an important aspect of a BGMS' analytical quality. METHODS: Based on ISO 15197:2013/EN ISO 15197:2015, system accuracy, measurement repeatability, and intermediate measurement precision were assessed. ISO 15197:2013 system accuracy criteria require that ?95% of individual BGMS' test strip lot results shall fall within +/-15 mg/dl or +/-15% of corresponding comparison method results (at glucose concentrations <100 mg/dl and ?100 mg/dl, respectively), and that ?99% of results fall within consensus error grid (CEG) zones A and B. Measurement repeatability was assessed using venous blood samples, whereas intermediate measurement precision was assessed using control solution samples. Standard deviation (SD) and coefficient of variation (CV) were calculated for glucose concentrations <100 mg/dl and ?100 mg/dl, respectively. Precision acceptance criteria are not specified by ISO 15197:2013. RESULTS: All three BGMS fulfilled system accuracy criteria with 96% to 98% of individual test strip lot's results falling within the acceptable accuracy limits. All measurement results fell within CEG zones A and B. For measurement repeatability, SD was ?3.3 mg/dl, and CV was ?3.9% for the investigated BGMS. Assessment of intermediate measurement precision showed SD ?1.3 mg/dl and CV ?3.0%. CONCLUSION: All three BGMS fulfilled system accuracy criteria of ISO 15197:2013. In absence of acceptance criteria, precision results were found to be consistent with the manufacturer's labeling of the investigated devices. PMID- 30286621 TI - Emotional experience of people with advanced liver disease: Secondary data analysis. AB - Introduction Patients with advanced liver disease live mainly in the community with treatment of complications provided for in-hospital. The illness trajectory of advanced liver disease is uncertain and most do not have access to end of life care. Gaps in knowledge and understanding of the patient experience of this condition have been identified. Methods Secondary analysis of 15 transcripts from in-depth interviews with people with advanced liver disease collected as part of a previous longitudinal study on the experience of liver disease. Transcripts were thematically analysed for emotional content. Results Fear, anger, sadness and guilt clearly featured in the person's experience of advanced liver disease. Certain causal factors were identified as provoking these emotional responses, including shock of diagnosis, uncertainty concerning illness, lack of coordinated care, worrying symptoms and sudden death. Humour emerged as a coping mechanism. Conclusion People living with advanced liver disease experience distressing emotions. It is helpful for clinicians, nurses and other healthcare support staff to have an appreciation of the person's emotional concerns in order to provide holistic care typical of a palliative approach. PMID- 30286619 TI - LINC00673 rs11655237 Polymorphism Is Associated With Increased Risk of Cervical Cancer in a Chinese Population. AB - Cervical cancer is the fourth most commonly diagnosed cancer and the fourth leading cause of cancer deaths in women worldwide. Few single-nucleotide polymorphisms associated with risk of cervical cancer have been identified, yet genetic predisposition contributes significantly to this malignancy. Long noncoding RNA LINC00673 has been widely explored for its role in the development and prognosis of many tumors, and 2 genome-wide association studies identified that LINC00673 rs11655237 was associated with susceptibility to pancreatic cancer. In the current study, using a case-control study design, we found rs11655237 significantly increased susceptibility of cervical cancer in a Chinese population (odds ratio = 1.27; 95% confidence interval = 1.08-1.50; P = .005). Expression of LINC00673 was significantly higher in adjacent normal tissues than in paired cancer tissues ( P < .01) and significantly lower in the cancer or paired adjacent normal tissues of patients with cervical cancer having rs11655237 allele A than in those having rs11655237 allele G ( P < .001). Our results indicate that LINC00673 rs11655237 is associated with increased risk of cervical cancer, possibly by downregulating LINC00673 expression in cervical tissues. PMID- 30286622 TI - Progressive freeze concentration of skimmed milk in an agitated vessel: Effect of the coolant temperature and stirring rate on process performance. AB - The aim of this study was to investigate the freeze-concentration of skimmed milk by a progressive freeze concentration process. The progressive freeze concentration procedure was performed at three different temperatures (-5, -10, and -15 C) and stirring rates (0, 500, and 1000 r/min). The solids concentration was determined and used for calculations of the efficiency of the process, concentrated yield, and experimental results validation. A general linear model was applied to determine the influence of the two factors studied, namely coolant temperature and agitation speed. In all tests, it was possible to concentrated skimmed milk with total solids content higher (P < 0.05) than ultra-high temperature skimmed milk. The highest concentration (P < 0.05) was achieved at low coolant temperature (-15 C) and high agitation speed (1000 r/min). The coolant temperature and the stirring rate both had a significant effect (P < 0.05) on the results of efficiency of the process and concentrated yield. Nevertheless, the parameter that showed the most significant effect in our study was the stirring rate. The tests presented a good fit since the root mean square values were below 25%. The freezing point temperatures of the concentrated milk fractions were lower than that of skimmed milk. Finally, the best-operating conditions in our study were achieved using a high coolant temperature (-5 C) and high mechanical stirring (1000 r/min), which was also the variable with the lowest (P < 0.05) retention of solids in the ice fraction. In our study, the progressive freeze concentration technique showed promise as an alternative for the dairy industry since it makes the development of new dairy products possible. PMID- 30286623 TI - Modeling of lactic acid fermentation of soy formulation with Lactobacillus plantarum HM1. AB - Lactic acid bacteria alone or with special adjunct probiotic strains are inevitable for the preparation of various specific functional foods. Moreover, because of their growth and metabolism, the final products are preserved for a certain time. Thus, growth dynamics of the lactic acid bacteria of the Fresco DVS 1010 culture ( Lactococcus lactis spp. lactis, Lactococcus lactis spp. cremoris, Streptococcus salivarius spp. thermophilus) during liquid-state fermentation of soya mashes and pH values within the process were analyzed in this study. Although milk is the most typical growth medium for the lactic acid bacteria, presumable viable counts of Fresco culture reached levels 109 CFU ml-1 after 8 h, representing 2-3 log increase in comparison to initial state (specific growth rates ranged from 1.06 to 1.64 h-1). After 21 days of storage period, the pH levels in the products were reduced to 4.50-4.70, representing a decrease of about 1.5-1.7 units. All prepared soybean products contained detectable amounts of raffinose-series oligosaccharides (0.25-0.68 g per 100 g) that were reduced in average by about 30.5% during period of 21 days. PMID- 30286624 TI - The safety of bevazicumab for the treatment of ovarian cancer. AB - INTRODUCTION: The safety profile of bevacizumab (BV) remains a challenging issue, in particular its role in fragile OC patients. Areas covered: In this literature review, we have analyzed safety data from Phase III trials evaluating the combination of BV plus standard chemotherapy in advanced or recurrent OC patients. In particular, our review aimed at clarifying the impact of the drug on fragile patients, and the correlation between BV and postoperative complications after cytoreductive surgery. Expert opinion: The addition of BV to standard chemotherapy regimens may cause unexpected side effects such as hypertension or proteinuria in up to 10% of women receiving the drug. BV administration is not associated with increase postoperative complications after cytoreductive surgery. Artero-venous thromboembolism and gastrointestinal perforation/fistula occurring in around 3% of OC patients treated with BV represent life-threatening events always requiring drug suspension. A closer monitoring is required in selected groups of women including: women with inflammatory bowel disease, or uncontrolled hypertension. Age itself is not a major contraindication, but older women should be carefully evaluated prior to start the drug. Finally, BV maintenance therapy should not be prematurely stopped due to minor events, since drug suspension may reduce survival. PMID- 30286625 TI - Ten-Year Follow-Up of Off-Pump and On-Pump Multivessel Coronary Artery Bypass Grafting: MASS III. AB - It was a randomized trial, and 308 patients undergoing revascularization were randomly assigned: 155 to off-pump coronary artery bypass (OPCAB) and 153 to on pump coronary artery bypass (ONCAB). End points were freedom from death, myocardial infarction, revascularization, and cerebrovascular accidents. The rates for 10-year, event-free survival for ONCAB versus OPCAB were 69.6% and 64%, (hazard ratio [HR]: 0.88; 95% confidence interval [CI] 0.86-1.02; P = .41), respectively. Adjusted Cox proportional hazard ratio was similar (HR: 0.92; 95% CI 0.61-1.38, P = .68). A difference occurred between the duration of OPCAB and ONCAB, respectively (4.9 +/- 1.5 vs 6.6 +/- 1.1 h, P < .001). Statistical differences occurred between OPCAB and ONCAB in the length of intensive care unit (ICU) stay (20 +/- 2.5 vs 48 +/- 10 hours, P < .001), time to extubation (5.5 +/- 4.2 vs 10.2 +/- 3.5 hours, P < .001), hospital stay (6.7 +/- 1.4 vs 9.2 +/- 1.3 days, P < .001), higher incidence of atrial fibrillation (AF; 33 vs 5 patients, P < .001), and blood requirements (46 vs 64 patients, P < .001). Grafts per patient was higher in ONCAB (3.15 vs 2.55 grafts, P < .001). No difference existed between the groups in primary composite end points at 10-year follow-up. Although OPCAB surgery was related to a lower number of grafts and higher incidence of AF, it had no effects related to long-term outcomes. PMID- 30286626 TI - Acupuncture Application in Chronic Kidney Disease and its Potential Mechanisms. AB - Chronic kidney disease (CKD) is an increasing major public health problem worldwide. The number of CKD patients on hemodialysis is growing rapidly as well. Acupuncture technique is one of the traditional Chinese medicine methods and has been used in a variety of diseases. Nowadays, the clinical application of acupuncture technique for CKD patients has become the focus for its effectiveness and security. In this paper, we will review the therapeutic effects and mechanisms of different acupuncture techniques for CKD patients. In patients with CKD, acupuncture improves renal function, reduces proteinuria, controls hypertension, corrects anemia, relieves pain, and controls many hemodialysis related complications such as uremic pruritus, insomnia and fatigue. The mechanisms are related to the regulation of sympathetic nerve and the activation of bioactive chemicals. In conclusion, acupuncture is proved to be beneficial for CKD patients. More research, however, is needed to verify the potential mechanisms. PMID- 30286627 TI - Comparative efficacy of brigatinib versus ceritinib and alectinib in patients with crizotinib-refractory anaplastic lymphoma kinase-positive non-small cell lung cancer. AB - OBJECTIVE: Brigatinib, ceritinib, and alectinib are approved to treat crizotinib refractory anaplastic lymphoma kinase-positive (ALK+) non-small cell lung cancer (NSCLC), but no trial has compared them head-to-head. A matching-adjusted indirect comparison (MAIC) was conducted to estimate the relative efficacy of these agents in the crizotinib-refractory setting. METHODS: MAIC is a propensity score-type method that adjusts for differences in baseline characteristics between trials to estimate relative efficacy. Analyses were based on patient level data from the ALTA trial for brigatinib and published summary-level trial data from ASCEND-1 and ASCEND-2 for ceritinib and NP28761 and NP28673 for alectinib. Objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were compared. RESULTS: After matching, all key baseline characteristics were balanced between trials. Compared with ceritinib, brigatinib was associated with longer PFS (ASCEND-1: median 15.7 vs 6.9 months, hazard ratio (HR) [95% confidence interval] = 0.38 [0.26-0.57]; ASCEND-2: median = 18.3 vs 7.2 months, HR = 0.33 [0.20-0.56]) and OS (ASCEND-1: not available; ASCEND-2: median 27.6 vs 14.9 months, HR = 0.33 [0.17-0.63]). Versus alectinib, brigatinib was associated with longer PFS (NP28761: median = 17.6 vs 8.2 months, HR = 0.56 [0.36 0.86]; NP28673: median = 17.6 vs 8.9 months, HR = 0.61 [0.40-0.93]); results for OS were inconclusive (NP28761: median = 27.6 vs 22.7 months, HR = 0.70 [0.42 1.16]; NP28673: median = 27.6 vs 26.0 months, HR = 0.66 [0.39-1.09]). ORR was similar. CONCLUSION: In crizotinib-refractory ALK + NSCLC patients, relative efficacy estimates suggest brigatinib may have prolonged PFS and OS vs ceritinib and prolonged PFS vs alectinib. PMID- 30286628 TI - A randomised controlled trial of excision versus invagination in the management of indirect inguinal hernial sac. AB - INTRODUCTION: Lichtenstein tension-free mesh hernioplasty of primary inguinal hernia is currently considered as the preferred method for the plastic reconstruction of inguinal hernia by the majority of surgeons. Several studies have examined the best way to manage the hernial sac in this surgery, but no consensus has been reached. This study was designed to compare the effects of excision of sac and invagination of sac on post-operative outcomes. METHODS AND METHODS: This prospective randomised study included a total of 70 patients with primary unilateral uncomplicated indirect inguinal hernia. Group A (35 patients) underwent high dissection and invagination of the hernial sac and group B (35 patients) underwent high ligation and excision of the hernial sac. The repair of the posterior wall of the inguinal canal was done according to Lichtenstein tension-free technique. The primary outcome of this study was postoperative pain and secondary outcomes were wound infection, chronic sepsis, sinus formation, persistent pain, testicular atrophy and recurrence during the one-year follow-up period. RESULTS: There was a significant difference (P < 0.01) in pain experienced by the patients in the immediate post-operative period between the two groups; group A experienced less postoperative pain than group B. There was no significant difference in incidence of infection between the groups. CONCLUSIONS: Invagination of the sac results in less postoperative pain compared with excision, with no significant difference in other postoperative outcomes.

AB - Colonic complications following pancreatitis are unusual events ranging from 1% to 15%. In a patient with a hostile abdomen and multiple previous laparotomies, surgical management of a closed-loop large-bowel obstruction risks significant morbidity and mortality for the patient, necessitating other strategies for management. Caecostomy in the management of large bowel obstruction is an often forgotten weapon in the general surgeons' armoury.

AB - We present the case of a 36-year-old man who presented with left-sided nasal obstruction and facial pain. Clinical examination and computed tomography revealed an inverted midline supernumerary tooth buckling and deviating the nasal septum to the left. Full surgical resection of the tooth was achieved through a minimally invasive endoscopic septoplasty with full resolution of symptoms. There is little precedent within the literature to guide our management in this case and therefore we offer a successful surgical treatment strategy.

PMID- 30286634 TI - A review of endovascular treatment of thoracic aorta disease. AB - INTRODUCTION: The development of thoracic endovascular aortic repair has altered the approach and reduced the risk of treating the majority of descending thoracic aortic conditions. Primarily developed for the exclusion of thoracic aortic aneurysms, it is now used in place of open repair surgery for most descending thoracic aortic diseases, and has also been used to treat aortic arch diseases in selected cases. METHODS: A literature search was conducted of Medline and Embase databases from January 2007 to February 2017, using the key words 'aortic disease', 'thoracic aorta' and 'endovascular repair'; 205 articles were identified, of which 25 studies were selected for review based on their relevance. FINDINGS: The key findings of the indications, techniques, outcomes, complications and comparisons with open surgical repair were extracted from the published studies and are summarised in this review. Thoracic endovascular aortic repair is the preferred choice of intervention for patients with descending thoracic aortic disease. With time, it has improved to be safer and has the potential to expand aortic treatment choices in future. PMID- 30286636 TI - Excision with primary midline closure compared with Limberg flap in the treatment of sacrococcygeal pilonidal disease: a randomised clinical trial. AB - BACKGROUND: Although several surgical techniques for treatment of sacrococcygeal pilonidal sinus (SPND) have been described, there is no consensus on the optimal surgical procedure. In this study we compared excision with primary closure and Limberg flap in the treatment of SPND. METHODS: This was a prospective randomised clinical trial in patients with SPND who were randomly allocated to one of two groups: group I (excision and primary closure) and group II (Limberg flap technique). The primary outcome of the trial was recurrence of SPND whereas postoperative complications, return to work and cosmetic results were the secondary outcomes. RESULTS: Sixty patients were included, with a mean age of 24.1 years and mean body mass index (BMI) of 26.8 kg/m2. Group 1 had significantly shorter operation time than group II. Both groups had similar hospital stay and comparable complication rates (43.3% vs 30%; P = 0.4). Group I had significantly higher recurrence rate (20% vs 0; P < 0.02) and significantly better cosmetic satisfaction score than group II. Being hairy (P = 0.04), positive family history (P = 0.03), diabetes mellitus (P = 0.005) and history of previous surgery for SPND (P = 0.01) were the significant predictors for recurrence. CONCLUSIONS: The Limberg flap is an effective technique for the treatment of SPND with very low recurrence rate and comparable complication rate and hospital stay to excision and primary closure. Excision and primary closure offered the advantages of quicker healing time, earlier resumption of daily activities, better cosmetic results, which may render it more suitable for patients with low risk for recurrence.

PMID- 30286638 TI - Emergent thyroidectomy with sternotomy due to acute respiratory failure with severe thyroid storm. AB - Huge cervical and mediastinal masses may lead to acute respiratory failure caused by laryngotracheal compression and airway obstruction. Thyroid storm is also a life-threatening endocrine emergency originating almost exclusively from uncontrolled Graves' disease. We report a case of a 42-year-old man with acute upper airway obstruction and tachycardia from progressive swelling of a giant thyroid, in conjunction with thyroid storm resulting from uncontrolled Graves' disease. Fibreoptic-assisted nasal intubation was performed while the patient was awake, immediately followed by emergency total thyroidectomy via a cervical and sternal approach. The patient had an uneventful postoperative course and recovered well. Respiratory failure due to swelling of a giant thyroid is a life threatening condition and should be treated immediately with endotracheal intubation while the patient is awake following emergent total thyroidectomy, even with a sternotomy.

AB - Gastric tube conduit is the method of choice for restoring continuity of the digestive track after a partial or total esophagectomy. Redundant gastric conduit (i.e. an elongated, floppy conduit) is a rare cause of dysphagia in patients with long survival. Gastric tube volvulus is exceedingly rare with only three cases described in the literature. We present the diagnostic and therapeutic course of a 57-year-old man who presented to our department with gastric tube volvulus 32 months after an Ivor-Lewis esophagectomy. Diagnosis was made with computed tomography and volvulus was reduced endoscopically. To the best of our knowledge, this is only the fourth case of gastric tube volvulus described in the English literature. This rare situation might be a consequence of a redundant gastric tube. Endoscopic volvulus decompression was successful in our case. PMID- 30286641 TI - Delayed presentation of iatrogenic ventriculoperitoneal shunt transection following laparoscopic weight loss surgery in a patient with idiopathic intracranial hypertension. AB - Idiopathic intracranial hypertension is strongly associated with central obesity and consequential raised intra-abdominal pressure. If left untreated it poses significant risk to vision and can eventually cause blindness. Owing to its pathophysiology, this condition is managed by both medical and surgical specialities. When medical management fails neurosurgeons commonly treat idiopathic intracranial hypertension by permanent cerebrospinal fluid peritoneal shunting. Weight reduction surgery provides patients who are obese with a multitude of benefits and it is not uncommon for the general surgeon to be presented with a patient with idiopathic intracranial hypertension and a cerebrospinal fluid peritoneal shunt in place. This provides a potential challenging situation in weight-loss surgical procedures. We describe an interesting case where laparoscopic bariatric surgery resulted in transection of the abdominal catheter with a delayed presentation of recurrent symptoms and an abdominal cerebrospinal fluid collection in a patient with idiopathic intracranial hypertension. We discuss how this could be avoided and its management. PMID- 30286642 TI - Wooden spatula sinusitis following maxillary expansion surgery.

PMID- 30286643 TI - A rare case of aortocaval fistula caused by type I endoleak after endovascular repair of abdominal aortic aneurysm. AB - In this rare case, an aortocaval fistula caused by a type I endoleak following endovascular repair of an abdominal aortic aneurysm (AAA) in a 75-year-old man was treated successfully with repeat endovascular aortic stent implantation. Postoperatively, the patient's symptoms were significantly improved, and angiography at nine months showed no endoleak in the aneurysm and no occlusion in the compressed inferior vena cava. Endovascular interventional surgery may be a safe and effective approach to treating AAA with concomitant aortocaval fistula. The use of covered stents to isolate the fistula from the venous side may not be necessary in the first stage of surgery. PMID- 30286644 TI - Will we ever cure nasal polyps? AB - BACKGROUND: Nasal polyposis is a benign hyperplastic growth of nasal mucosa. There is a paucity of evidence on the prevalence and incidence of nasal polyposis. Although nasal polyps can be asymptomatic, they can cause a spectrum of nasal problems including nasal obstruction, rhinorrhoea, nasal congestion, anosmia resulting in ageusia. Nasal polyps are mostly associated with chronic rhinosinusitis, The current management of chronic rhinosinusitis with nasal polyps is controversial and is not curative. METHODS: A Medline search was conducted, using the keywords 'rhinosinusitis', 'sinusitis', 'classification' and ''aetiology. FINDINGS: The current treatment of nasal polyposis in chronic rhinosinusitis with nasal polyps is still challenging. Emerging research through endotypes profiling aims to better understand the complexities of this heterogeneous disease to personalise treatment and provide a cure. Randomised controlled trials aim to provide robust evidence for current management options. PMID- 30286645 TI - Suture choice to reduce occurrence of surgical site infection, hernia, wound dehiscence and sinus/fistula: a network meta-analysis. AB - BACKGROUND: There are many options and little guiding evidence when choosing suture types with which to close the abdominal wall fascia. This network meta analysis investigated the effect of suture materials on surgical site infection, hernia, wound dehiscence and sinus/fistula occurrence after abdominal surgery. The aim was to provide clarity on whether previous recommendations on suture choice could be followed with confidence. METHODS AND METHODS: In February 2017, the Cochrane Central Register of Controlled Trials, Medline, EMBASE and Science Citation Index Expanded were searched for randomised controlled trials investigating the effect of suture choice on these four complications in closing the abdomen. A reference search of identified trials was performed. Prisma guidelines and the Cochrane risk of bias tool were followed in the data extraction and synthesis. Two review authors screened titles and abstracts of trials identified. A random effect model was used for the surgical site infection network based on the deviance information criterion statistics. RESULTS: Thirty one trials were included (11,533 participants). No suture material reached the predetermined 90% probability threshold for determination of 'best treatment' for any outcome. Pairwise comparisons largely showed no differences between suture types for all outcomes measured. However, nylon demonstrated a reduction in the occurrence of incisional hernias with respect to two commonly used absorbable sutures: polyglycolic acid (odds ratio, OR 1.91; 95% confidence interval, CI, 1.01-3.63) and polyglyconate (OR 2.18; 95% CI 1.17-4.07). CONCLUSIONS: No suture type can be considered the 'best treatment' for the prevention of surgical site infection, hernia, wound dehiscence and sinus/fistula occurrence. PMID- 30286646 TI - The diagnostic yield of computed tomography in the management of acute flank pain and the emergency intervention rate for a proven acute ureteric stone. AB - INTRODUCTION: The diagnostic and management pathways for patients presenting with acute flank pain are complex. Although computed tomography (CT) of the kidneys, ureters and bladder (KUB) is the gold standard investigation for urolithiasis, the multitude of differential diagnoses must also be considered in the context of long-term risk from ionising radiation. This study investigated the integrated role and diagnostic yield of non-contrast CT in cases of acute flank pain. METHODS: A retrospective cohort study was undertaken of 1,442 consecutive patients investigated with CT KUB between March 2013 and February 2015. The primary outcome was diagnostic yield of CT with secondary outcomes being predictors of need for urological intervention. RESULTS: A cause for acute flank pain was identified in 717 patients (50%), there was an incidental finding in 389 patients (27%) and normal imaging was reported in 336 patients (23%). A diagnosis was more commonly made in male than in female patients (70% vs 40%) and with increasing age (46% in patients aged <30 years, 56% in those aged 30-49 years and 63% in those aged >=50 years). The overall rate for an ipsilateral urinary tract stone was 41%. Factors strongly associated with emergency intervention included stone size >10mm (odds ratio [OR]: 11.7, 95% confidence interval [CI]: 3.3-42.7), stones located at the pelviureteric junction (OR: 7.8, 95% CI: 2.6-22.9), C reactive protein >50mg/l and <=100mg/l (OR: 15.2, 95% CI: 5.1-45.3), and estimated glomerular filtration rate <=30ml/min (OR: 5.8, 95% CI: 1.5-21.8). CONCLUSIONS: This contemporary study identifies age and sex as independent variables affecting the diagnostic yield of CT KUB in cases of acute flank pain, and highlights factors associated with a need for emergency intervention in proven ureteric stones. PMID- 30286647 TI - Percutaneous cholecystostomy... why, when, what next? A systematic review of past decade. AB - INTRODUCTION: Percutaneous cholecystostomy tube drainage has played a vital role in management of cholecystitis in patients where surgery is not appropriate. However, management differs from unit to unit and even between different consultants in the same unit. We conducted this systematic review to understand which of these resulted in the best patient outcomes. METHODS: We conducted a systematic review using the PubMed database for publication between January 2006 to December 2016. Keyword variants of 'cholecystostomy' and 'cholecystitis' were combined to identify potential relevant papers for inclusion. FINDINGS: We identified 46 studies comprising a total of 312,085 patients from 20 different countries. These papers were reviewed, critically appraised and summarised in table format. Percutaneous cholecystostomy tube drainage is an important treatment modality with an excellent safety profile. It has been used successfully both as a definitive procedure and as a bridge to surgery. There continues to be great variation, however, when it comes to the indications, timing and management of these drains. As far as we are aware, this is the only systematic review to cover the past 10 years. It provides a much-needed update, considering all the technological development and new treatment options in laparoscopic surgery and interventional radiology.

AB - INTRODUCTION: Minimally invasive parathyroidectomy (MIP) for primary hyperparathyroidism is dependent upon accurate prediction of single-gland disease on the basis of preoperative imaging and biochemistry. The aims of this study were to validate currently available predictive models of single-gland disease in two UK cohorts and to determine if these models can facilitate MIP. MATERIAL AND METHODS: We collected data prospectively from our weekly follow-up virtual clinic over a continuous four-month period between July and September 2017. RESULTS: In total, we reviewed 409 patients. Following virtual clinic consultation, 68.5% of our patients were discharged from further follow-up. The majority of our patients (male 57.7%, female 55.5%) were of working age. The satisfaction scores were high, at 90.1%, and there were no reported adverse events as a result of using the virtual clinic. Our calculated cost savings were L18,744, with a predicted 12 month cost saving of L56,232. The creation of additional face-to-face clinic capacity has created an estimated 12-month increase in tariff generation for our unit of L72,072. In total, 4623 travel miles were avoided by patients using the virtual clinic, with an estimated avoided carbon footprint of 0.35-1.45 metric tonnes of CO2e, depending on mode of transport. Our predicted 12-month avoided carbon footprint is 1.04-4.04 metric tonnes of CO2e. CONCLUSIONS: Our virtual clinic model has demonstrated a trifecta of positive outcomes, namely, clinical, financial and environmental benefits. The environmental importance and benefits of a virtual clinic should be promoted as a social enterprise value when engaging stakeholders in setting up such a urological service. We propose the adoption of our virtual clinic model in those urological units considering this method of telemedicine.

AB - INTRODUCTION: While patients with acute uncomplicated appendicitis may be treated conservatively, those who suffer from complicated appendicitis require surgery. We describe a logistic regression equation to calculate the likelihood of acute uncomplicated appendicitis and complicated appendicitis in patients presenting to the emergency department with suspected acute appendicitis. MATERIALS AND METHODS: A cohort of 895 patients who underwent appendicectomy were analysed retrospectively. Depending on the final histology, patients were divided into three groups; normal appendix, acute uncomplicated appendicitis and complicated appendicitis. Normal appendix was considered the reference category, while acute uncomplicated appendicitis and complicated appendicitis were the nominal categories. Multivariate and univariate regression models were undertaken to detect independent variables with significant odds ratio that can predict acute uncomplicated appendicitis and complicated appendicitis. Subsequently, a logistic regression equation was generated to produce the likelihood acute uncomplicated appendicitis and complicated appendicitis. RESULTS: Pathological diagnosis of normal appendix, acute uncomplicated appendicitis and complicated appendicitis was identified in 188 (21%), 525 (59%) and 182 patients (20%), respectively. The odds ratio from a univariate analysis to predict complicated appendicitis for age, female gender, log2 white cell count, log2 C-reactive protein and log2 bilirubin were 1.02 (95% confidence interval, CI, 1.01, 1.04), 2.37 (95% CI 1.51, 3.70), 9.74 (95% CI 5.41, 17.5), 1.57 (95% CI 1.40, 1.74), 2.08 (95% CI 1.56, 2.76), respectively. For the same variable, similar odds ratios were demonstrated in a multivariate analysis to predict complicated appendicitis and univariate and multivariate analysis to predict acute uncomplicated appendicitis. CONCLUSIONS: The likelihood of acute uncomplicated appendicitis and complicated appendicitis can be calculated by using the reported predictive equations integrated into a web application at www.appendistat.com. This will enable clinicians to determine the probability of appendicitis and the need for urgent surgery in case of complicated appendicitis.

PMID- 30286650 TI - Does the Intercollegiate Membership of the Royal College of Surgeons (MRCS) examination predict 'on-the-job' performance during UK higher specialty surgical training? AB - INTRODUCTION: The Intercollegiate Membership of the Royal College of Surgeons (MRCS) is a mandatory examination to enter higher surgical specialty training in the UK. It is designed to help to ensure that successful candidates are competent to practice as higher surgical trainees. The annual review of competence progression (ARCP) assesses trainees' competence to progress to the next level of training and can be interpreted as a measure of 'on-the-job' performance. We investigated the relationship between MRCS performance and ARCP outcomes. MATERIALS AND METHODS: All UK medical graduates who passed MRCS (Parts A and B) from 2007 to 2016 were included. MRCS scores, attempts and sociodemographics for each candidate were crosslinked with ARCP outcomes (satisfactory, unsatisfactory and insufficient evidence). Multinomial logistic regression was used to identify potential independent predictors of ARCP outcomes. RESULTS: A total of 2570 trainees underwent 11,064 ARCPs; 1589 (61.8%) had only satisfactory outcomes recorded throughout training; 510 (19.9%) had at least one unsatisfactory outcome; and 471 (18.3%) supplied insufficient evidence. After adjusting for age, gender, first language and Part A performance, ethnicity (non-white vs white, OR 1.36, 95% CI 1.08 to 1.71), Part B passing score (OR 0.98, 95% CI 0.98 to 1.00) and number of attempts at Part B (two or more attempts vs one attempt, OR 1.50, 95% CI 1.16 to 1.94) were found to be independent predictors of an unsatisfactory ARCP outcome. CONCLUSIONS: This is the first study to identify predictors of ARCP outcomes during higher surgical specialty training in the UK and provides further evidence of the predictive validity of the MRCS examination. PMID- 30286651 TI - Surgery for Cushing's disease in pregnancy: our experience and a literature review. AB - Cushing's syndrome in pregnancy is a rare phenomenon and there is limited literature on its management. Cushing's disease in pregnancy is even less common and there is little guidance to help in the treatment for this patient group. Diagnosis of Cushing's syndrome in pregnancy is often delayed due to overlap of symptoms. In addition, there are no validated diagnostic tests or parameters documented. We present a case of a 30-year-old woman presenting to the antenatal clinic at 13 weeks of pregnancy with high suspicion of Cushing's disease. Her 21 week fetal scan showed a congenital diaphragmatic hernia and she underwent pituitary magnetic resonance imaging, which confirm Cushing's disease. She successfully underwent transsphenoidal adenomectomy with histology confirming a corticotroph adenoma. Tests following transsphenoidal surgery confirmed remission of Cushing's disease and she underwent an emergency caesarean section at 38 weeks. Unfortunately, her baby died from complications associated with the congenital abnormality 36 hours after birth. The patient remains in remission following delivery. To date, there have been no reported cases of congenital diaphragmatic hernia associated with Cushing's disease in pregnancy. In addition, we believe that this is only the eighth reported patient to have undergone successful transsphenoidal surgery for Cushing's disease in pregnancy. PMID- 30286652 TI - A selective non-operative approach to thoracic stab wounds is safe and cost effective - a South African experience. AB - INTRODUCTION: Penetrating thoracic trauma is common and costly. Injuries are frequently and selectively amenable to non-operative management. Our selective approach to penetrating thoracic trauma is reviewed and the effectiveness of our clinical algorithms confirmed. Additionally, a basic cost analysis was undertaken to evaluate the financial impact of a selective nonoperative management approach to penetrating thoracic trauma. MATERIALS AND METHODS: The Pietermaritzburg Metropolitan Trauma Services electronic regional trauma registry hybrid electronic medical records were reviewed, highlighted all penetrating thoracic traumas. A micro-cost analysis estimated expenses for active observation, tube thoracostomy for isolated pneumothorax greater than 2 cm and tube thoracostomy for haemothorax. Routine thoracic computed tomography does not form part of these algorithms. RESULTS: Isolated thoracic stab wounds occurred in 589 patients. Eighty per cent (472 cases) were successfully managed nonoperatively. Micro costing shows that active observation costs 4,370 ZAR (L270), tube thoracostomy for isolated pneumothorax costs 6,630 ZAR (L400) and tube thoracostomy for haemothorax costs 21,850 ZAR (L1,310). DISCUSSION: Penetrating thoracic trauma places a striking financial burden on our limited resources. Diligent and serial clinical assessments, alongside basic radiology and stringent management criteria, can accurately stratify patients to correct clinical algorithms. CONCLUSION: Selective nonoperative management for penetrating thoracic trauma is safe and effective. Routine thoracic computed tomography is unnecessary in all patients with isolated thoracic stab wounds, which can be reserved for a select group who are identifiable clinically. Routine thoracic computed tomography would not be financially prudent across Pietermaritzburg Metropolitan Trauma Services. Government action is required to reduce the overall incidence of such trauma to save resources and patients. PMID- 30286653 TI - Are on-the-day group and save samples required for elective shoulder, hip and knee arthroplasties? AB - INTRODUCTION: Historically, patients undergoing an elective hip, knee or shoulder arthroplasty regularly required blood transfusions. Improved surgical techniques and perioperative optimisation have significantly decreased the requirement for blood transfusions. Currently, our patients have two group and save samples taken: one six weeks preoperatively and one on admission. This study aims to determine whether a second group and save is required prior to primary elective hip, knee or shoulder arthroplasty. METHODS: All cases of elective arthroplasty from a single centre were retrospectively analysed over a 16-month period. Each case was reviewed to determine those who had a group and save at preassessment, group and save at the time of the operation and the timing and number of blood products transfused. RESULTS: A total of 711 elective arthroplasty procedures were completed with 48 patients requiring a transfusion during their admission. 9.9% of hip arthroplasty patients, 3.8% of knee arthroplasty patients and 4.9% of shoulder arthroplasty patients required a transfusion. The majority of the transfusions occurred at least 24 hours postoperatively with 0.84% of patients requiring an intraoperative transfusion. DISCUSSION: The vast majority of transfusions were delivered more than 24 hours following the procedure, demonstrating that routinely cross-matched blood products are superfluous to requirements. It is our suggestion that a formal group and save be completed only if the need for a blood transfusion is formally established, leading to a significant cost saving, a reduction in clinical work load and patients having to undergo fewer procedures. PMID- 30286654 TI - The rare case of an extraperitoneal ureteral herniation into the inguinal canal of a 12-year-old boy. AB - Ureteric herniation into the inguinal canal is a rare condition in adults and even more so in the paediatric population. These hernia types can be categorised as paraperitoneal or extraperitoneal. The former are the only varieties encountered in the paediatric literature, where patients are generally infants, while the latter phenomenon is seen in 20% of ureteric herniations in adults. We present a case of an extraperitoneal ureteric herniation into the inguinal canal in a 12-year-old boy with previous surgery for cloacal exstrophy, analyse the existing literature on the condition and make the speculation that the extraperitoneal variety is an adult variant seen in this child because of weakness in the surrounding structures as a result of previous surgery.

PMID- 30286656 TI - 30-day complication rates and patient-reported outcomes following day case primary lumbar microdiscectomy in a regional NHS spinal centre. AB - INTRODUCTION: Advances in surgical and anaesthesia technique have reduced length of stay for lumbar discectomy. Current evidence suggests that daycase surgery is associated with improved patient satisfaction, faster recovery, reduced infection rates and financial savings. We present our microdiscectomy daycase protocol, together with 30-day postoperative complication rates and patient reported outcomes in an NHS setting. METHODS AND METHODS: We retrospectively studied all patients that met a locally agreed daycase protocol for lumbar microdiscectomy and were operated upon and discharged on the same calendar day between 1 March 2013 and 31 December 2015. RESULTS: A total of 134 patients underwent primary daycase microdiscectomy (70 males, 64 females). The cohort had a mean age of 41 years (range 16-82 years). Some 96% (n = 129) were single-level procedures, 93% were unilateral (n = 125) and 81% (n = 109) took place at either L4/L5 or L5/S1. All patients were discharged on the same day as admission and operation. Four patients re-presented to hospital within 30 days and three were discharged from the emergency department within four hours following a clinical review. One patient required an inpatient stay for a washout of a superficial postoperative infection. Significant improvements (P < 0.05) were found postoperatively for back pain and leg pain on self-reported visual analogue scores and Oswestry Disability Index. CONCLUSION: In this study, we present a safe and effective protocol for day case lumbar microdiscectomy. Our 30-day postoperative complication rate of under 1% is comparable to that of traditional inpatient primary lumbar microdiscectomy. Patient-reported outcome measures revealed significant improvement in both pain and functional scores. PMID- 30286657 TI - Rhabdomyosarcoma of the middle ear cavity presenting with Horner's syndrome. AB - Rhabdomyosarcoma is a rare malignant tumour of striated muscle accounting for 3% of all primary soft tissue tumours of the middle ear cavity. We describe a unique case of a rhabdomyosarcoma of the middle ear cavity in a four-year-old boy, presenting as an otherwise asymptomatic ipsilateral Horner's syndrome. This case involved tumour erosion through the tensor tympani semicanal, accessing the carotid canal and the sympathetic plexus running through it. This child was treated successfully with chemotherapy and proton beam therapy, and remains disease free at six years of follow-up. This case highlights the importance of investigating patients with non-resolving ear infections, polyps or granulation tissue. PMID- 30286658 TI - Gastro-oesophageal fistula in an achalasia patient following myotomy as an unusual cause of heartburn. AB - We report a case of delayed presentation of a gastro-oesophageal fistula following a Heller myotomy and anterior fundoplication for achalasia in a 28-year old man. After a period of symptom resolution following initial operation, dysphagia and severe heartburn commenced temporarily, related to non-steroidal anti-inflammatory drug (NSAID) use. Endoscopy demonstrated a secondary opening in the lower oesophagus and a barium swallow showed an oesophageal fistula to the stomach. Currently, reasonable symptom control has been obtained on double dose pantoprazole. Barium study best demonstrated the abnormality. NSAIDs should possibly be avoided in cases of severe dysmotility of the oesophagus. PMID- 30286659 TI - Combined ultrasound and Sestamibi scintigraphy provides accurate preoperative localisation for patients with primary hyperparathyroidism. AB - INTRODUCTION: Minimally invasive parathyroidectomy has advantages over the traditional bilateral neck exploration for the surgical treatment of primary hyperparathyroidism. It requires accurate localisation of the parathyroid pathology prior to surgery. The best method of preoperative localisation in a district general hospital setting is not well understood. METHODS: All patients who underwent parathyroidectomy for primary hyperparathyroidism from 2008 to 2016 were identified from a prospectively maintained database. Operative findings were correlated with radiological and histological results. Sensitivity and specificity of ultrasound, sestamibi scintigraphy and the two together were calculated for diagnostic precision and compared. RESULTS: One hundred and eighty four patients met the inclusion criteria, of whom 81.5% had a histological diagnosis of a parathyroid adenoma. Ultrasound had higher sensitivity than sestamibi scintigraphy. Used together, ultrasound and sestamibi scintigraphy performed better than either ultrasound or sestamibi scintigraphy alone (P< 0.001). Twenty-two of 184 cases had no lesion located by either ultrasound or sestamibi scintigraphy preoperatively. Where neither ultrasound nor sestamibi scintigraphy located the lesion, additional computed tomography led to the excision of parathyroid pathology in one in ten patients. CONCLUSION: The combination of ultrasound and sestamibi scintigraphy provides the highest sensitivity of preoperative localisation. This approach led to a high success rate of minimally invasive parathyroidectomy. Where preoperative localisation is not achieved with ultrasound or sestamibi scintigraphy, computed tomography adds little additional benefit. In this setting other modalities of localisation such a selective venous sampling, intraoperative methylene blue or intraoperative parathyroid hormone levels could be considered. PMID- 30286660 TI - Computed tomography colonography: a new threat to the spleen? AB - We present a rare and previously undocumented potential complication of computed tomography (CT) colonography. CT colonography is a commonly performed investigation with a relatively low risk of complications. While splenic injury is a well-documented complication after colonoscopy, it has never been reported following CT colonography. A 64-year-old man presented with severe abdominal pain four hours after CT colonography. CT of his abdomen and pelvis revealed appearances consistent with intra-abdominal bleeding secondary to splenic injury. The patient immediately underwent an emergency laparotomy and splenectomy, revealing a grade III splenic capsular tear. Histological evaluation of splenic tissue showed normal morphology with no evidence of malignancy. While the aetiology of the patient's splenic injury remains uncertain, normal histopathology and the chronology of events represents an almost certain link to CT colonography.

AB - PURPOSE: The purpose of this study is to conduct a systematic review of interventions for the treatment of non-progressive dysarthria in adults. MATERIALS AND METHODS: Five electronic databases (PubMed, Embase, CINAHL, PSYCINFO, Cochrane Collaboration) were searched for all studies that described and evaluated treatment used for non-progressive dysarthria in adults. Studies were included if (1) participants were adults (18+ years) with a confirmed diagnosis of non-progressive dysarthria, (2) participants received intervention with pre-post outcome data, and (3) the article was published between 2006 and 2017 (including early online publications). Data extracted included the number of participants; etiology; dysarthria type and severity; age; gender; presence of a control group; intervention tasks, frequency and duration; outcome measures; and conclusions. Data extraction was completed by a member of the research team independently and crosschecked by another team member. RESULTS: Of the 6728 articles identified, 21 met the inclusion criteria. The predominant study design was a case study or case series. The methodological quality of the studies varied. Typically, the interventions included impairment-based and activity level tasks targeting conversation. Approximately half of the interventions adhered to a treatment manual. CONCLUSIONS: The evidence base to guide treatment for non progressive dysarthria is increasing, with interventions showing promise in results, participant numbers, and positive participant feedback. Implications for rehabilitation The evidence base to guide treatment for non-progressive dysarthria is increasing, but remains limited. The majority of evidence is of moderate methodological quality. The emergence of new research indicates that health professionals need to be continuously aware and critically appraise new literature in the area. PMID- 30286662 TI - Examination of burden of skeletal-related events in patients naive to denosumab and intravenous bisphosphonate therapy in bone metastases from solid tumors population. AB - OBJECTIVES: Skeletal-related events (SREs), i.e. pathologic fractures, spinal cord compression, surgery and radiation to bone, are serious skeletal complications that occur frequently in patients with bone metastases (BMs) from solid tumors (STs). Clinical guidelines recommend treatment with denosumab and intravenous bisphosphonates (IVBPs) to prevent SREs. However, therapy may be delayed by physicians due to perceived low risk of SREs or for other clinical reasons. This study estimated SRE incidence rates in treatment-naive (i.e. no denosumab or IVBPs) patients with BMs from STs in the US. METHODS: In this retrospective cohort study adult patients with diagnoses of BM and ST between 1 January 2008 and 31 March 2015 were identified from MarketScan Databases. All patients had >=6 months of data before the first BM diagnosis date (index date) and were followed for >=6 months from the index date until the earliest of inpatient death, initiation of denosumab/IVBP therapy or end of data. The Kaplan Meier curve was used to estimate cumulative incidence of SREs. The incremental healthcare cost of SREs was estimated and compared to propensity score matched non-SRE patients. RESULTS: A total of 47,052 patients met the study criteria. Using the Kaplan-Meier method the cumulative incidences of SREs among treatment naive patients were 39.9% (95% confidence internal [CI]: 39.4-40.4), 46.3% (95% CI: 45.8-46.8), 52.5% (95% CI: 51.9-53.2) and 59.4% (95% CI: 58.6-60.3) by month 6, 12, 24 and 48 post index date, respectively. The SRE group was associated with higher all-cause total healthcare cost per-patient-per-year compared to those without SREs ($168,277 vs. $101,020, p < .001). CONCLUSIONS: Almost half (46.3%) of the treatment-naive population with BMs from STs experience SREs within 1 year of the first BM diagnosis. SREs were associated with an average $67,257 additional healthcare cost annually. Given the high SRE burden in these patients, early initiation of prophylactic therapy should be considered. PMID- 30286663 TI - Examining quality of care for individuals treated for mental health using the HEDIS mental health quality measures. AB - OBJECTIVE: This descriptive study examined the quality of care received by individuals with serious mental illness observed in clinical care using established Healthcare Effectiveness Data and Information Set (HEDIS) measures for individuals with serious mental illness. METHODS: Administrative claims (Medicaid, Medicare, and commercial) from a national health and well-being company were used to identify adults with schizophrenia or bipolar disorder. Performance rates for five HEDIS mental health quality measures were computed. Sub-group analyses examined each HEDIS measure by those who were medication adherent vs non-adherent, and by typical vs atypical antipsychotics. RESULTS: Eighty-nine percent of the Medicaid population received a diabetes screening (vs 79% for national benchmark Medicaid rates), 81% (vs 69%) received monitoring for diabetes, 88% (vs 79%) received monitoring for cardiovascular disease, 63% (vs 60%) were adherent with antipsychotic medication, and 34% (vs 61%) had a follow up visit with a mental health practitioner within 30 days of a discharge. The rates for individuals with Medicare coverage were similar or marginally higher than those reported for those with Medicaid coverage, while rates for the commercially insured population were lower than the other groups. CONCLUSIONS: Most (>65%) individuals with serious mental illness received the recommended screening and monitoring for diabetes and cardiovascular disease. Barriers to and reasons for lack of follow-up should be investigated to guide future interventions to improve follow-up after hospitalization for individuals with serious mental illness.

AB - AIM: The aim is to assess whether the national policy for evidence-based rehabilitation with a focus on facilitating return-to-work is being implemented in health-care units in Sweden and which factors influence its implementation. METHODS: A survey design was used to investigate the implementation. Data were collected at county council management level (process leaders) and clinical level (clinicians in primary and secondary care) using web surveys. Data were analyzed using SPSS, presented as descriptive statistics. RESULTS: The response rate among the process leaders was 88% (n = 30). Twenty-eight percent reported that they had already introduced workplace interventions. A majority of the county councils' process leaders responded that the national policy was not clearly defined. The response rate among clinicians was 72% (n = 580). Few clinicians working with patients with common mental disorders or musculoskeletal disorders responded that they were in contact with a patient's employer, the occupational health services or the employment office (9-18%). Nearly, all clinicians responded that they often/always discuss work-related problems with their patients. CONCLUSIONS: The policy had been implemented or was to be implemented before the end of 2015. Lack of clearly stated goals, training, and guidelines were, however, barriers to implementation. Implications for rehabilitation Clinicians' positive attitudes and willingness to discuss workplace interventions with their patients were important facilitators related to the implementation of a nationwide policy for workplace interventions/rehabilitation. A lack of clearly stated goals, training, and guidelines were barriers related to the implementation. The development of evidence-based policies regarding rehabilitation and its implementation has to rely on very structured and clear descriptions of what to do, preferably with the help of practice guidelines. Nationwide implementation of rehabilitation policies has to allow time for preparation including communication of goals and competence assurance in a close collaboration with the end users, namely clinicians and patients.

PMID- 30286665 TI - Partial tubal devascularisation: a novel procedure for tubal conservation in ectopic pregnancy. AB - Ectopic pregnancy is a serious condition that complicates 1-2% of pregnancies. Using surgical management is efficient, but may have an impact on future fertility. Although conservative tubal surgery has not been shown to have a significant advantage over a salpingectomy in terms of the future fertility potential, the conservative surgical techniques remain widely-utilised, particularly in the context of a contralateral diseased or absent tube. We hereby report a case series of a novel procedure to conserve the fallopian tube with the minimal risk of an incisional site bleeding through a partial segmental devascularisation. This technique seems to be an efficient method to minimise the intraoperative bleeding, limit the need for a blood transfusion, and yields a higher success rate of the procedure without jeopardising the blood supply and vitality of the tubes. Impact Statement What is already known on this subject? Conservative surgery has a significant value in women with a contralateral absent or diseased tube. However, a conservative management could be challenging due to the significant bleeding which can be encountered during the surgery. What the results of this study add? The partial devascularisation technique could achieve an adequate haemostasis by blocking the ascending blood supply only to the affected segment of the fallopian tube. What the implications are of these findings for clinical practice and/or further research? A partial devascularisation is a successful conservative surgical treatment option in most patients when the procedure is indicated. PMID- 30286666 TI - Chemotherapy for cervical cancer in pregnancy.

Patients may have symptoms disproportionate to the severity or the severity may be unclear. In addition, the optimal timing of intervention in patients with severe disease may be controversial. Areas covered: This article examines the role of stress echocardiography for assessment of patients with low-flow, low gradient aortic stenosis, asymptomatic severe valve disease and patients where symptoms are discordant to the resting severity of valve disease. Expert commentary: Stress echocardiography helps clinicians determine the true severity of valve disease and may identify the cause of symptoms in patients with only mild/moderate disease. The data provided by stress echocardiography will help determine the appropriate management strategy and the correct timing of intervention. PMID- 30286668 TI - Dietary patterns, dietary intakes and the risk of type 2 diabetes: results from the Hefei Nutrition and Health Study. AB - A total of 1776 Chinese adults, aged 40-60 years, had been recruited to participate in the Hefei Nutrition and Health Study started in 2012. Three major dietary patterns were identified, "High-salt and high-fat", "Traditional Chinese" and "Western" dietary patterns. After adjusting for potential confounders, there is no significant difference in the effect of different dietary pattern quintiles on the risk of type 2 diabetes (T2D). However, compared with lowest quintile intakes, the adjusted odds ratio of T2D for highest quintile intakes of bread and noodle, rice noodle and coarse grain were 2.45 (95% CI: 1.17, 5.12), 0.34 (95% CI: 0.17, 0.92), 0.27 (95% CI: 0.14, 0.51), with corresponding p trend being .002, .375, .003, respectively. Our study suggests that high intakes of bread and noodle are significantly associated with increased risk of T2D, while high intakes of rice noodle and coarse grain are remarkably correlated with decreased risk of T2D. PMID- 30286670 TI - Pharmacological thrombolysis: the last choice for salvaging free flaps. AB - Microvascular free flap transfer has become a prevailing surgery with a failure rate of <5%. However, pedicle thrombosis occurs more frequently than indicated by the failure rate. This difference is due to the successful salvage of failing flaps. During exploration, thrombi are often encountered at anastomotic sites, whereas these causes could not explain vascular compromise in other patients. Thus, we hypothesized that thrombogenic processes might occur at remote sites, specifically within microvessels of the transferred flap. This study retrospectively evaluated 323 patients who underwent microvascular free flap transfer between March 2012 and October 2016 at Korea University Guro Hospital. All patients requiring emergency exploration within 7 days after surgery were retrospectively reviewed. Of patients, 15 required explorative surgery for suspected circulatory compromise. Eight were diagnosed with thrombosis at the perianastomotic site and salvaged in accordance with our protocol. There was no detectable thrombosis at the anastomotic site in seven patients, including one patient in whom thrombosis resolved with topical papaverine application and heparinization. The remaining six patients were diagnosed with intra-flap microthrombosis without discernable thrombosis at the anastomotic site. All patients were treated following our urokinase administration protocol and salvaged without complications. Possible external causes should first be evaluated when salvaging free flaps; in the absence of such evidence, urokinase administration may be utilized as a last resort. This study is the first report describing the effectiveness of pharmacological thrombolysis in resolving intra flap microthrombosis. Furthermore, a safe and efficient urokinase administration protocol is suggested for perianastomotic thrombosis and intra-flap microthrombosis.

PMID- 30286669 TI - The insight of in vitro and in silico studies on cholinesterase inhibitors from the roots of Cimicifuga dahurica (Turcz.) Maxim. AB - Cholinesterases (ChEs) are enzymes that break down neurotransmitters associated with cognitive function and memory. We isolated cinnamic acids (1 and 2), indolinones (3 and 4), and cycloartane triterpenoid derivatives (5-19) from the roots of Cimicifuga dahurica (Turcz.) Maxim. by chromatography. These compounds were evaluated for their inhibitory activity toward ChEs. Compound 1 was determined to have an IC50 value of 16.7 +/- 1.9 MUM, and to act as a competitive inhibitor of acetylcholinesterase (AChE). Compounds 3, 4 and 14 were found to be noncompetitive with IC50 values of 13.8 +/- 1.5 and 6.5 +/- 2.5 MUM, and competitive with an IC50 value of 22.6 +/- 0.4 MUM, respectively, against butyrylcholinesterase (BuChE). Our molecular simulation suggested each key amino acid, Tyr337 of AChE and Asn228 of BuChE, which were corresponded with potential inhibitors 1, and 3 and 4, respectively. Compounds 1 and 4 were revealed to be promising compounds for inhibition of AChEs and BuChEs, respectively. PMID- 30286672 TI - Differences in the toxicity of cerium dioxide nanomaterials after inhalation can be explained by lung deposition, animal species and nanoforms. AB - Considerable differences in pulmonary responses have been observed in animals exposed to cerium dioxide nanoparticles via inhalation. These differences in pulmonary toxicity might be explained by differences in lung deposition, species susceptibility or physicochemical characteristics of the tested cerium dioxide nanoforms (i.e. same chemical substance, different size, shape, surface area or surface chemistry). In order to distinguish the relative importance of these different influencing factors, we performed a detailed analysis of the data from several inhalation studies with different exposure durations, species and nanoforms, namely published data on NM211 and NM212 (JRC repository), NanoAmor (commercially available) and our published and unpublished data on PROM (industry provided). Data were analyzed by comparing the observed pulmonary responses at similar external and internal dose levels. Our analyses confirm that rats are more sensitive to developing pulmonary inflammation compared to mice. The observed differences in responses do not result purely from differences in the delivered and retained doses (expressed in particle mass as well as surface area). In addition, the different nanoforms assessed showed differences in toxic potency likely due to differences in their physicochemical parameters. Primary particle and aggregate/agglomerate size distributions have a substantial impact on the deposited dose and consequently on the pulmonary response. However, in our evaluation size could not fully explain the difference observed in the analyzed studies indicating that the pulmonary response also depends on other physicochemical characteristics of the particles. It remains to be determined to what extent these findings can be generalized to other poorly soluble nanomaterials. PMID- 30286673 TI - Histological study of costal cartilage after transplantation and reasons for avoidance of postoperative resorption and retention of cartilage structure in rats. AB - BACKGROUND: Limited information is available on the biological status of transplanted cartilage from which the perichondrium has been removed. This article describes the histological and three-dimensional structural picture of cartilage, using green fluorescent protein (GFP) transgenic rats and normal wild rats. METHODS: Three sections of costal cartilage were harvested from 10-week-old wild rats. One section was used as a specimen while two were subcutaneously collected from the dorsal region of 10-week-old GFP rats at 4 and 8 weeks post transplant. The experiment was performed in two randomized groups. The perichondrium was removed from transplanted cartilage in the first group and perichondrium of transplanted cartilage remained intact in the second group. Histology and focused ion beam/scanning electron microscope (FIB/SEM) tomography were used to evaluate the transplanted cartilage. RESULTS: All 40 transplanted sections were harvested and no infections, exposure or qualitative change of cartilage matrix were seen following transplant. Histological analyses showed that the surface layer of the GFP-negative transplanted cartilage was replaced with GFP-positive chondrocytes 8 weeks post-transplant in the first group. A three-dimensional layer of perichondrium-like tissue reconstructed around the cartilage at 8 weeks was confirmed, resembling normal perichondrium. However, the GFP-positive chondrocytes were not replaced in the second group. CONCLUSIONS: The cell renewal of chondrocytes is necessary for subcutaneously transplanted cartilage to maintain its tissue composition over a long period of time. The histological and ultrastructural analyses revealed that cells from recipient tissue generated new chondrocytes even when cartilage was implanted after removing the perichondrium. PMID- 30286674 TI - Maternal and umbilical cord blood level of macrophage migration inhibitory factor and insulin like growth factor in Sudanese women with preeclampsia. AB - Preeclampsia is a health concern and it is the main cause of maternal and perinatal mortality. The macrophage migration inhibitory factor (MIF) and insulin like growth factor-I (IGF-I) are factors associated with preeclampsia. A case control (45 women in each arm) study was conducted at Saad Abualila Maternity Hospital (Khartoum, Sudan). The cases were of women who had preeclampsia, and the controls were healthy pregnant women. The clinical and obstetrical characteristics were gathered using a questionnaire and MIF and IGF-I levels were measured by ELISA. The cases and the controls (45 in each arm) were matched in their basic data. In comparison with the healthy controls, while the median (interquartile range) of the maternal MIF [8.221 (7.334-8.820) vs. 3.717 (2.385 4.883) ng/mL, p < .001] was significantly higher, the levels of the maternal IGF 1 [1.250 (0.670-1.980) vs. 1.939 (1.056-2.752), ng/mL, p < .001] were significantly lower in the women with preeclampsia. There was no significant difference in the cord levels of both the MIF and IGF-1 between the cases and controls. In linear regression, preeclampsia was the only factor that was significantly associated with the log of the maternal MIF (-0.338 ng/mL, p < .001), IGF-1 (0.293 ng/mL, p = .005) and cord MIF (-0.340 ng/mL, p < .001) levels. Impact statement What is already known on this subject? Macrophage migration inhibitory factor (MIF) has a pivotal role in pro-inflammatory processes during pregnancy/labour and its levels have been correlated with preeclampsia. Insulin like factors are produced in the liver under the stimulation of the growth hormones; they stimulate cell differentiation proliferations. IGF-I may be implicated in the pathogenesis of the adverse effects of preeclampsia (mainly the birth weight). What do the results of this study add? The current study showed a significantly higher level of MIF and lower level IGF-1 in the women with preeclampsia. Thus, both MIF and IGF-1 might have a role in the pathogeneses of preeclampsia. What are the implications of these findings for clinical practice and/or further research? MIF and IGF might be used as reliable markers to detect preeclampsia. These markers might be used as preventive or therapeutic elements for preeclampsia. PMID- 30286675 TI - Is there any relationship between benign endometrial pathologies and metabolic status? AB - The aim of this study was to assess the relation between benign endometrial pathologies (polyp and/or hyperplasia without atypia) and the metabolic status (insulin resistance and metabolic syndrome) of the patients. A total of 168 cases were enrolled in the study. The patients were classified according to the presence of benign endometrial pathologies and their menopausal status. Then, the subjects were evaluated according to the metabolic syndrome criteria and the presence of an insulin resistance. The insulin resistance levels of the cases were analysed by four different methods. Obesity and a waist circumference of greater than 88 cm were observed significantly more in the study group with endometrial pathologies (p = .005 and p < .001, respectively). It was also observed that a fasting blood glucose level of higher than 110 mg/dL increased the risk of developing endometrial polyps and/or hyperplasia without atypia by almost five folds (OR: 5.26, 95% CI: 1.25-22.12). Furthermore, an insulin resistance was found to be significantly high in the study group (p = .002). Based on the observed significant relationship between an insulin resistance and benign endometrial pathologies, it can be concluded that insulin resistance plays an important role in the development of benign endometrial pathologies. Impact Statement What is already known on this subject? Metabolic anomalies such as obesity, type 2 diabetes, hypertension and dyslipidaemia play an important role in abnormal endometrial proliferation. Also, these metabolic anomalies have been known as risk factors for type I endometrial cancer. What the results of this study add? A significant relationship between an insulin resistance and benign endometrial pathologies was observed. What the implications are of these findings for clinical practice and/or further research? Based on this finding, we concluded that an insulin resistance may play an important role in the development of benign endometrial pathologies. The prevention and the treatment of obesity as a key factor of developing an insulin resistance, may reduce not only the incidence of malignant endometrial pathologies, but also the incidence of benign pathologies and of a malignant transformation. PMID- 30286676 TI - Pharmacokinetic study of the prokinetic ABCs liquiritigenin, naringenin and hesperitin following the oral administration of Si-Ni-San decoction to functional dyspepsia patients. AB - 1. The pharmacokinetics (PKs) analysis of compounds absorbed after the oral administration of Si-Ni-San (SNS) decoction to functional dyspepsia (FD) patients was designed to detect whether the effects were similar to prokinetics administered to healthy rats, without ethical limitation. 2. First, the absorbed compounds, liquiritigenin (L), naringenin (N) and hesperitin (H) in the plasma were identified by UPLC-MS/MS following the oral administration of SNS decoction to subjects with FD. Next, the natural ratio of LNH in the SNS decoction was determined by UPLC. Third, gastric emptying and intestinal transit after the oral administration of LNH, in combination or alone, was compared with those observed after SNS administration in healthy rats. Additionally, the clinical PKs of LNH was studied. 3. The prokinetic efficacy of LNH administered at their natural ratios (7.5:5:1) increased dose-dependently and was better than the observed efficacy when administered alone in rats. Analysis of the clinical PK parameters, calculated using a one-compartment model, showed that the Cmax parameters of LNH in 3, 4 and 4 h were 639.17, 410.00 and 181.67 MUg/L, respectively. 4. The clinical herbal PK analysis of the absorbed LNH preclinical prokinetic compounds, in their natural ratio from SNS, highlights the impact of an herbal translational pharmacology study. PMID- 30286677 TI - Early Onset Allergic Proctitis in a Preterm Neonate-A Case Report and Review of the Literature. AB - Cow's milk protein allergy/intolerance (CMPA/CMPI) is a common entity in the pediatric population with a nonspecific presentation ranging from gastrointestinal symptoms to systemic manifestations. Most infants with CMPI are term, and symptoms often appear in the week following the introduction of cow's milk-based formula. There is typically a significant delay in the onset of milk allergy in premature infants compared to full term. We report a rare case of a premature neonate who presented with symptoms of CMPA within the first 2 days of life. PMID- 30286678 TI - Accuracy of internet images of ligamentous knee injuries. AB - BACKGROUND: The internet is an easily accessible resource for both providers and patients. Despite this, the internet is not peer reviewed, leaving searches subject to inaccuracies, especially with regards to medical information. The purpose of this study was to review internet images of anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), and lateral collateral ligament (LCL) tears using two popular search engines: Google and Bing. METHODS: A search query was performed on both Google and Bing for the following terms: 'ACL tear', 'PCL tear', 'MCL tear' and 'LCL tear'. The first 100 images of each individual search were analyzed by three independent orthopedists. RESULTS: The inter-rater reliability was very good for PCL tear on Bing (Cronbach's alpha = 0.89) and excellent (Cronbach's alpha > 0.9) for the remainder of the search queries. When comparing Google to Bing, the only significant difference occurred in the ACL group, with Bing returning a significantly greater number of correct images 60%, 95% CI: 53.2 - 66.7%) compared to Google (45% correct, 95% CI: 38.1-51.8%), p = 0.034. With regards to the other ligaments Bing was more accurate than Google for PCL (39% versus 38%), and LCL (32% to 30%). Both sites were 48% accurate for MCL tear. CONCLUSION: Ultimately, our study revealed that physicians should take an active role in making high quality, easy to understand medical resources and anatomic diagrams available to their patients to avoid confusion and enhance understanding when querying the internet for additional information regarding their condition. PMID- 30286679 TI - Adherence to medication in children and adolescents with asthma: methods for monitoring and intervention. AB - INTRODUCTION: Poor adherence in children with asthma is a major cause of asthma attacks and poor control, leads to large health-care costs, and has been identified as a factor in asthma deaths. However, it is difficult to detect and frequently overlooked leading to inappropriate escalation of asthma treatment. There is a need for cost effective ways to monitor adherence in order to intervene to change this modifiable behavior. Areas covered: Several measurement tools have been developed to assess adherence in adults and children with asthma. The current methods for measuring adherence, both subjective and objective, have several flaws and even the current gold standard, electronic monitoring devices (EMDs), has limitations. This review will outline and critique the adherence monitoring tools and highlight ways in which they have been used for the purpose of intervention. Expert commentary: Although advances have been made in adherence monitoring, we still have some way to go in creating the ideal monitoring tool. There are no validated tailored self-monitoring questionnaires for children with asthma and most objective measures, such as prescription refill rate and weighing canisters, overestimate adherence. Current EMDs, although useful, need improved accuracy to ensure that both actuation and inhalation are measured, and the devices need to be affordable for use in routine health-care practice. PMID- 30286680 TI - The importance of inhibitor eradication in clinically complicated hemophilia A patients. AB - INTRODUCTION: Inhibitors against factor VIII (FVIII), which develop in around 20 30% of patients with severe hemophilia A, represent a significant complication of on-demand or prophylactic FVIII therapy. Currently, the main treatment option for inhibitor patients is eradication using immune tolerance induction (ITI) therapy. Areas covered: This article reviews inhibitor eradication in clinically complicated hemophilia A patients. The benefits and disadvantages of ITI therapy are discussed, with reference to the new nonfactor replacement agents such as emicizumab, which are becoming available. Expert commentary: At present, ITI therapy is the method of choice for all inhibitor patients, but as alternative treatment options become increasingly available, this may change in the future. Despite the development of nonfactor replacement agents, ITI therapy is likely to maintain a key role in the management of inhibitor patients, although changes in ITI therapy regimens including the timing of ITI initiation, the dosing regimen, the management of thrombotic risk or safety, laboratory assessment of ITI outcomes, and maintenance treatment after ITI success, may be necessary. PMID- 30286681 TI - The influence of language and culture on cognitive assessment tools in the diagnosis of early cognitive impairment and dementia. AB - INTRODUCTION: Cognitive assessment tools measure cognitive impairment and complement biomarkers to link cognitive symptoms with pathophysiological processes underlying dementia. However, language and cultural differences in multilingual populations can influence the interpretation of cognitive assessment tools when applied in cross-cultural and multinational studies. Areas covered: This article examines the influence of culture and language on the interpretation of the Mini-Mental State Examination, Montreal Cognitive Assessment, and Alzheimer's Disease Assessment Scale-cognitive subscale, which are more commonly used worldwide. It discusses how this impacted multinational studies. Lastly, it presents language-neutral tools such as the Visual Cognitive Assessment Test, which do not require translation when applied in multilingual populations. Expert commentary: Linguistic and cultural variation within tools due to translation and differences in administration introduce method bias and differential item functioning, which influence the interpretation of cognitive scores in multinational studies. The ultimate goal is to have a tool that accurately measures cognitive impairment, yet with minimal influence from linguistic, cultural, educational, and demographic differences, through concerted international efforts to harmonize the development and validation of tools. While recently developed visual-based language-neutral tools show promise in the early detection of cognitive impairment, further validation will be required for these tools to be applied internationally. PMID- 30286682 TI - Advances in contraceptive vaginal rings: what does the future hold? AB - INTRODUCTION: Contraceptive vaginal rings (CVRs) are good contraceptive options because they do not require skilled providers, are self-administered, and show a higher stability of drug diffusion. Area covered: This article provides a review of the developments made with CVRs over the past number of years, while giving focus to the latest CVRs that have gone through clinical development. The author of the article also provides an expert perspective on the future of these useful therapeutic options. Expert opinion: Pharmacokinetic studies have shown that segesterone, an absorbable progestin that is used alone or in combination with ethinyl estradiol (EE) or E2, is the CVR of choice at this present time. Indeed, segesterone has demonstrated safety and efficacy as a CVR and is also an appropriate option for lactating women, as they are not absorbed orally. However, good cycle control is important for improved CVR adherence. CVRs that allow the combination of more than one drug may unravel another multi-purpose use when combined with microbicides and could provide combined protection to women who wish to protect themselves from pregnancy and sexually transmitted infection. PMID- 30286683 TI - Automated monitoring of mouse feeding and body weight for continuous health assessment. AB - Routine health assessment of laboratory rodents can be improved using automated home cage monitoring. Continuous, non-stressful, objective assessment of rodents unaware that they are being watched, including during their active dark period, reveals behavioural and physiological changes otherwise invisible to human caretakers. We developed an automated feeder that tracks feed intake, body weight, and physical appearance of individual radio frequency identification tagged mice in social home cages. Here, we experimentally induce illness via lipopolysaccharide challenge and show that this automated tracking apparatus reveals sickness behaviour (reduced food intake) as early as 2-4 hours after lipopolysaccharide injection, whereas human observers conducting routine health checks fail to detect a significant difference between sick mice and saline injected controls. Continuous automated monitoring additionally reveals pronounced circadian rhythms in both feed intake and body weight. Automated home cage monitoring is a non-invasive, reliable mode of health surveillance allowing caretakers to more efficiently detect and respond to early signs of illness in laboratory rodent populations. PMID- 30286684 TI - Youth Speak Out on School Food Environments. AB - In Philadelphia, over 40% of youth are overweight or obese. The objective in this assessment was to learn about urban residents' perspectives regarding the local food environment and its impact on eating behaviors. Using photo-elicitation, 20 adolescents reflected on their food environments through photographs and corresponding interviews. Without specific prompting from interviewers, every participant raised concerns about their school food environments, which they commonly found to be unhealthy and unappealing. Participants' responses reflected four themes: (1) mixed reviews regarding the healthfulness of school vending machines, (2) lunch from home versus lunch from school, (3) factors that influenced food choice at school, and (4) critiques of school food environments. Students embraced the photo-elicitation approach as a way to convey their concerns and to suggest opportunities for improvements. School nurses, who are trusted by students and school personnel, are well-positioned to solicit student input and advocate for healthier school food environments. PMID- 30286685 TI - Voices We Forget-Danish Students Experience of Returning to School Following Parental Bereavement. AB - This study explores how Danish students experience returning to school following parental bereavement. Eighteen focus group interviews with 39 participants aged 9 to 17 years were conducted. All participants had experienced the loss of a primary caregiver. Data collection was divided into two phases. In Phase I, 22 participants from four grief groups were interviewed 4 times over the course of a year. During Phase II, confirmatory focus groups were undertaken with the 17 participants. This article explores findings related to the four themes of initial school response, long-term support, challenges within the class, and academic challenges. The study found that (a) students struggle to reconnect with classmates following the return to school and often feel alone, (b) schools fail to have guidelines in place for what they are allowed to do if becoming sad the class, and (c) schools seem to forget their loss as time passes. PMID- 30286686 TI - A Model of Transcorporeal Communication: Communication Toward/With/to the Deceased. AB - Research indicates that people maintain a connection with deceased loved ones, which can be healthy for the bereaved individuals. To maintain these bonds, people readily admit to communicating with the deceased. Although communication with the deceased shares similarities with traditional models of interpersonal communication, it is distinctly different. Interviews with 20 individuals revealed support for a model of transcorporeal communication, communication to people who do not maintain a physical presence. This communication includes the components of sender, inner representation of the deceased as receiver, message, feedback based on what the sender believes the deceased would say, and a metaphysical element. Implications of transcorporeal communication for griefwork are also discussed. PMID- 30286687 TI - Event Centrality and Bereavement Symptomatology: The Moderating Role of Meaning Made. AB - The centrality of a loss to a bereaved individual's identity is associated with greater symptomatology, whereas meaning made of a loss is associated with positive outcomes. This article examines meaning made as a moderator of the relationship between event centrality and symptomatology. Our sample consisted of 204 bereaved undergraduate university students. Centrality was assessed using the Centrality of Events Scale, meaning made was assessed using the Integration of Stressful Life Experiences Scale, and symptomatology was assessed using the posttraumatic stress disorder Checklist-Civilian and Inventory of Complicated Grief-Revised. Meaning made had a significant moderating effect on the relationship between centrality and both measures of symptomatology. At lower levels of meaning made, centrality had a strong and positive association with symptomatology; at higher levels of meaning made, this association became weaker. These results suggest that meaning made is the key to understanding how centrality affects bereavement outcomes. PMID- 30286688 TI - Rapid Central Vein Assessment (RaCeVA): A systematic, standardized approach for ultrasound assessment before central venous catheterization. AB - Ultrasound technology has revolutionized the practice of safer vascular access, for both venous and arterial cannulation. The ability to visualize underlying structures of the chest, neck, and upper/lower extremities provides for greater success, speed, and safety with all vascular access procedures. Ultrasound not only yields superior procedural advantages but also provides a platform to perform a thorough assessment of the vascular structures to evaluate vessel health, viability, size, and patency, including the location of other important and best avoided anatomical structures-prior to performing any procedures. Such assessment is best performed using a systematic and standardized approach, as the Rapid Central Vein Assessment, described in this study. PMID- 30286689 TI - Psychometric Characteristics of Duke Social Support Index Among Elderly Suicide in Rural China. AB - We recruited 242 elderly suicides and 242 controls above 60 years to conduct face to-face interviews by psychological autopsy to examine the psychometric characteristics of the Duke Social Support Index (DSSI) in rural China. DSSI had high internal consistency, with Cronbach's alphas of .89 and .90 in suicides and controls, respectively. DSSI was significantly and negatively correlated to loneliness in both samples. Confirmatory factor analysis basically supported the original structure of DSSI, but Item 4 had low factor loading in controls. In conclusion, DSSI has satisfactory reliability and acceptable validity in evaluating social support in the elderly suicide study in China. PMID- 30286690 TI - Ethnoregional Dynamics of Intimate Partner Violence Against Women in Nigeria. AB - Intimate partner violence (IPV) is a reality the average Nigerian woman has to grapple with everyday. Ethnicity and place of residence play a pivotal role in the social realities of Nigerian women, especially with their experience of IPV. However, there is a paucity of reviews examining the impact of ethnicity and place of residence on women's experiences of IPV in Nigeria. This study seeks to explore the ethnoregional dynamics of IPV from the range of studies undertaken on the subject matter. Eighteen studies meant the inclusion criteria for analysis. The major criteria for selecting studies for analysis were peer-reviewed studies on IPV against women and studies on a Nigerian population, regardless of the nationality of the authors. Databases like the University of Saskatchewan Library, ProQuest, Sociological Abstracts, and Journal Storage ( JSTOR) were used in searching for peer-reviewed studies. The study revealed that Igbo women tend to experience IPV more than Yoruba and Hausa women. The study also found that rural women tend to experience IPV more than urban women. The study points out some of the services available for female victims of IPV and the possible strategies that can be adapted to reach them effectively. PMID- 30286691 TI - Anti-inflammatory effects of Kaempferol on Helicobacter pylori-induced inflammation. AB - : Inflammation induced by Helicobacter pylori infection related to gastric carcinogenesis. In this study, we have investigated the anti-inflammatory effect and its mechanism of kaempferol in the inflammatory response caused by H. pylori infection in vitro. We found that kaempferol reduced the expression of pro inflammatory cytokines (TNF-alpha, IL-1beta, and IL-8) and production of IL-8 in AGS cells. In addition, kaempferol suppressed translocation of cytotoxin associated gene A (CagA) and vacuolating cytotoxin A (VacA) of H. pylori to AGS cells. It was due to decreased transcription of type IV secretion system (T4SS) components involved in CagA injection and secretion system subunit protein A (SecA) of type V secretion system (T5SS) involved in VacA secretion by kaempferol. In conclusion, kaempferol shows the anti-inflammatory effect by suppressing the translocation of CagA and VacA proteins and leading to the down regulation of pro-inflammatory cytokines. ABBREVIATIONS: CagA: cytotoxin associated gene A; VacA: vacuolating cytotoxin A; T4SS: type IV secretion systems; SecA: secretion system subunit protein A; T5SS: type V secretion system. PMID- 30286692 TI - The hyoid bone: an overview. AB - The hyoid bone is a small horseshoe-shaped bone located between the mandible and the shoulder girdle. It is classified as a sesamoid bone which means it is a freely floating bone. However, it is anything but freely floating. The hyoid bone is a vestigial structure and is found as part of the tongue in lower animal forms. The hyoid bone is attached to the base of the skull, the mandible, the tongue, the larynx, and the scapular belt. Even though the hyoid bone is an important structure, it has not received the attention that it deserves. It participates in the function of speech, respiration, mastication, and swallowing, as well as maintaining the patency of the airway between the oropharynx and the tracheal rings. Knowledge of the anatomy and physiology of the hyoid is necessary for recognition of the clinical presentation of related disorders and syndromes. PMID- 30286693 TI - Ganglion Cytology: A Novel Rapid Method for the Diagnosis of Equine Dysautonomia. AB - Equine dysautonomia (grass sickness) is characterized by autonomic neuronal degeneration and is often fatal. As outbreaks occur, rapid diagnosis is essential but confirmation currently requires histological examination. This study evaluated diagnostic accuracy of cytological examination of cranial cervical ganglion (CCG) scrapings for dysautonomia diagnosis. CCG smears from 20 controls and 16 dysautonomia cases were stained with May-Grunwald Giemsa (MGG), hematoxylin and eosin (HE), and cresyl fast violet (CFV), with HE-stained histological sections of CCG as gold standard for diagnosis. Examining all 3 stains together, the sensitivity and specificity were 100%. Occasional individual smears (4/107, 3.7%) were nondiagnostic due to low cellularity, and in a few individual smears the final diagnosis was correct but more tentative (CFV: 5/33 [15.1%], HE: 2/34 [5.9%], and MGG: 4/36 [11.1%]), due to low cellularity or suboptimal cell morphology. CCG cytology was considered reliable for rapid postmortem diagnosis of equine dysautonomia, particularly using MGG. PMID- 30286694 TI - A meta-analytic perspective on the valid use of subjective human judgement to make medical school admission decisions. AB - While medical educators appear to believe that admission to the medical school should be governed, at least in part, by human judgement, there has been no systematic presentation of evidence suggesting it improves selection. From a fair testing perspective, legal, ethical, and psychometric considerations, all dictate that the scientific evidence regarding human judgement in selection should be given consideration. To investigate the validity of using human judgements in admissions, multi-disciplinary meta-analytic research evidence from the wider literature is combined with studies from within medical education to provide evidence regarding the fairness and validity of using interviews and holistic review in medical school admissions. Fourteen studies, 6 of which are meta analytic studies that summarized 292 individual studies, were included in the final review. Within these studies, a total of 33 studies evaluated the reliability of the traditional interview. These studies reveal that the interview has low to moderate reliability (~.42) which significantly limits its validity. This is confirmed by over 100 studies examining interview validity which collectively show interview scores to be moderately correlated with important outcome variables (corrected value ~.29). Meta-analyses of over 150 studies demonstrate that mechanical/formula-based selection decisions produce better results than decisions made with holistic/clinical methods (human judgement). Three conclusions regarding the use of interviews and holistic review are provided by these meta-analyses. First, it is clear that the traditional interview has low reliability and that this significantly limits its validity. Second, the reliable variance from interview scores appears moderately predictive of outcomes that are relevant to consider in medical school admission. And third, the use of holistic review as a method of incorporating human judgement is not a valid alternative to mechanical/statistical approaches as the evidence clearly indicates that mechanistic methods are more predictive, reliable, cost efficient, and transparent. PMID- 30286695 TI - Identification and expression analysis of MinD gene involved in plastid division in cassava. AB - Cassava is a tropical crop known for its starchy root and excellent properties. Considering that starch biosynthesis in the amyloplast is affected by its division, it appears conceivable that the regulation of plastid division plays an important role in starch accumulation. As a member of the Min system genes, MinD participated in the spatial regulation of the position of the plastid division site.In our studies, sequence analysis and phylogenetic analysis showed that MeMinD has been highly conserved during the evolutionary process. Subcellular localisation indicated that MeMinD carries a chloroplast transit peptide and was localised in the chloroplast. Overexpression of MeMinD resulted in division site misplacement and filamentous formation in E. coli, indicating that MeMinD protein was functional across species. MeMinD exhibited different spatial and temporal expression patterns which was highly expressed in the source compared to that in the sink organ. PMID- 30286696 TI - Japanese Rice Wine can reduce psychophysical stress-induced depression-like behaviors and Fos expression in the trigeminal subnucleus caudalis evoked by masseter muscle injury in the rats. AB - We determined if Japanese Rice Wine (Sake) had inhibitory effects on stress induced enhancement of masseter muscle (MM) nociception in the rats. Male rats were subjected to the repeated forced swim stress (FS) or sham conditionings from Day -3 to -1. Daily administration of Sake or saline was conducted after each stress conditioning. At Day 0 the number of Fos positive cells, a marker for neural activity, was quantified at the trigeminal subnucleus caudalis (Vc) region by MM injury with formalin. FS increased MM-evoked Fos expression in the Vc region, which was inhibited by Sake compared to saline administration. Sake did not alter the number of Fos positive cells under sham conditions, indicating that inhibitory roles of Sake on neural activity in the Vc region were seen under FS conditions. These findings indicated that Sake had inhibitory roles on stress induced MM nociception at the Vc region in our experimental conditions. PMID- 30286697 TI - Case Series of 23 Patients Who Developed Fatal Radiation Pneumonitis After Stereotactic Body Radiotherapy for Lung Cancer. AB - The purpose of this study was to examine the characteristics and treatment plans of patients who experienced fatal radiation pneumonitis after stereotactic body radiation therapy for primary or oligometastatic lung cancer. Records of 1789 patients treated with stereotactic body radiation therapy for primary or oligometastatic lung cancer were retrospectively reviewed to identify those who developed fatal radiation pneumonitis. Twenty-three (1.3%; 18 men and 5 women) patients developed fatal radiation pneumonitis after stereotactic body radiation therapy for lung cancer; their median age was 74 years. The mean Krebs von den Lungen-6 level and percent vital capacity were 1320 U/mL and 82%, respectively. Prestereotactic body radiation therapy computed tomography revealed pulmonary interstitial change in 14 (73.7%) of 19 patients in whom computed tomography data could be reviewed. Seven (30.4%) of 23 patients had regularly used steroids. The median time duration between stereotactic body radiation therapy commencement and pneumonia symptom appearance was 75 (range: 14-204) days. Median survival time following pneumonia symptom appearance was 53 (range: 4-802) days. The 6- and 12 month overall survival rates were 34.8% and 13.0%, respectively. The 6-month overall survival rates in patients with and without heart disease were 50.0%, 16.7%, and 46.7% for heart disease existence, respectively. There were 4 patients in whom fatal radiation pneumonitis occurred within 2 months after stereotactic body radiation therapy and who died within 1 month. Three of them had no pulmonary interstitial change before stereotactic body radiation therapy, but had heart disease. In summary, the survival time in this case series was generally short but varied widely. More than half of the patients had pulmonary interstitial change before stereotactic body radiation therapy, although immediately progressive fatal radiation pneumonitis was also observed in patients without pulmonary interstitial change. True risk factors for fatal radiation pneumonitis should be examined in a prospective study with a larger cohort. PMID- 30286699 TI - Bizarre extensive erythematous plaques on the abdomen. AB - We present a rare case report of a 28-year-old man with a five-month history of bizarre extensive erythematous plaques on the abdomen extending in a dermatomal fashion to the left upper back. PMID- 30286698 TI - In their own words: stressors facing medical students in the millennial generation. AB - BACKGROUND: Medical student exposure to stressors is associated with depression, burnout, somatic distress, decreases in empathy, serious thoughts about dropping out of medical school, suicidal ideation, and poor academic performance. Despite this, there have been no recent, multicenter, qualitative studies assessing medical students' perceptions of their greatest stressor(s). OBJECTIVE: The goal of this study was to identify the most significant stressors noted by medical students themselves, in order to inform the development of programs and policies to reduce medical student distress. DESIGN: Medical students from the nine schools in the state of Florida were invited to complete an anonymous online questionnaire assessing wellness and distress. Students were notified that all responses were voluntary and that individual responses would not be linked to themselves or their program. This paper focuses on students' responses to fixed response items regarding their experience of stress and open-ended responses to the following question: 'What do you consider to be the greatest stressor(s) facing medical students?' Qualitative data were analyzed using the Grounded Theory method of data analysis. RESULTS: Results confirmed the impact of several stressors highlighted in previous studies (e.g., excessive workload, difficulties with studying and time management, conflicts in work-life balance and relationships, medical school peer relations, health concerns, and financial stressors). However, students also reported unique system-level concerns that have not consistently been highlighted in past research (e.g., medical school administrative failures, concerns about lack of assistance with career planning, and assessment-related performance pressure. CONCLUSIONS: Though individually focused interventions have demonstrated some success, medical students self report stressors that may be better addressed through system-level changes.

AB - Granuloma multiforme (GM) is a chronic granulomatous skin condition which is clinically characterised by annular lesions mainly over sun-exposed areas and histologically by focal necrobiosis and histiocytic granulomas. Its significance lies in the fact that it can clinically resemble tuberculoid leprosy and hence it can be missed. Here, we report a case of GM from India in a 55-year-old female agriculturist, with multiple asymptomatic large annular rings of papules over the photo-distributed areas. Histopathology helps in confirming the diagnosis and in differentiating it from similar clinical and histologic mimics such as granuloma annulare, tuberculoid leprosy, interstitial granulomatous dermatitis or annular sarcoid. Though a high degree of suspicion is needed to diagnose GM, it should be considered as a differential for various annular conditions.

AB - Formation of Cu, Zn superoxide dismutase 1 (SOD1) protein inclusions within motor neurons is one of the principal characteristics of SOD1-related amyotrophic lateral sclerosis (ALS). A hypothesis as to the nature of SOD1 aggregation implicates oxidative damage to a solvent-exposed tryptophan as causative. Here, we chart discovery of a phenanthridinone based compound (Lig9) from the NCI Diversity Set III by rational methods by in silico screening and crystallographic validation. The crystal structure of the complex with SOD1, refined to 2.5 A, revealed that Lig9 binds the SOD1 beta-barrel in the beta-strand 2 and 3 region which is known to scaffold SOD1 fibrillation. The phenanthridinone moiety makes a substantial pi - pi interaction with Trp32 of SOD1. The compound possesses a significant binding affinity for SOD1 and inhibits oxidation of Trp32; a critical residue for SOD1 aggregation. Thus, Lig9 is a good candidate from which to develop a new library of SOD1 aggregation inhibitors through protection of Trp32 oxidation.

AB - A potato fraction library was constructed to investigate functional secondary metabolites from 8 cultivars: Kitahime, Pilka, Sakurafubuki, Atlantic, Toyoshiro, Snowden, Kitamurasaki, and Northern Ruby, which were divided into flower, leaf, stem, roots, tuber peel, and tuber. Each fraction was a semi-purified extract and about 800 fractions were prepared for the library. They were analyzed by DAD LC/MS to obtain structural information and were evaluated for various biological activities. LC/MS data showed that each part had a specific characteristic for their constituents supported by principal component analysis (PCA). Approximately 40% of fractions showed significant biological activities at 30 MUg/mL, especially the flower fractions showed strong cytotoxicity. PCAs based on the activity and LC/MS data suggested that the strong cytotoxicity of flowers was derived from a complex mixture of potato glycoalkaloids. In addition, tuber peel fractions showed strong antimalarial activity, which had not been reported before. Also, some fractions showed significant antibacterial activities.

AB - : To establish a reliable and practical ergothioneine (ERG) supply, we employed fermentative ERG production using Aspergillus oryzae, a fungus used for food production. We heterologously overexpressed the egt-1 and -2 genes of Neurospora crassa in A. oryzae and succeeded in producing ERG (231.0 mg/kg of media, which was 20 times higher than the wild type).

PMID- 30286704 TI - The effects of a calf pump device on second half performance of a simulated soccer match in competitive youth players. AB - During soccer matches, performance decrements have been reported that relate to both physical abilities and technical skills. To investigate the effects of low frequency electrical stimulation LFES (VeinoplusSport(r), Ad Rem Technology, France) administered during half-time recovery on performance alterations during the second half. Twenty-two highly trained young players undertook a soccer-match simulation (SAFT90). During half-time, they were randomly assigned to LFES group or Placebo group. Each half was split into 3 bouts of 12 minutes. Following each bout, maximal strike speed (MSS), sprint test (ST), maximal sprint accelerations (MA) and metabolic power (MP) were determined in both groups. Arterial (AF) and venous flows (VF) were measured at rest and at the end of half-time. LEFS group exhibited beneficial effects on performance compared to the Placebo group with a likely effect for MSS, ST, MA, and a possible effect for MP. AF and VF increased statistically more in LEFS group compared to Placebo group. The use of specific calf-pump LFES during half-time of a youth simulated soccer match attenuated the decrease in performance during the second half compared to Placebo group. This effect is most marked at the beginning of the second half with regards to explosive parameters. PMID- 30286705 TI - Canine Cerebral Intravascular Lymphoma: Neuropathological and Immunohistochemical Findings. AB - Intravascular lymphoma (IVL) is a rare angiotropic large-cell lymphoma in which neoplastic lymphocytes proliferate within the lumina of small blood vessels in the absence of a primary extravascular mass or leukemia. This study included 10 cases of canine IVL restricted to the CNS. Dogs had an average age of 8 years and neurological signs mainly referred to brain involvement such as depression, seizures, and ambulatory deficits. Gross examination at necropsy showed focal extensive or multiple hemorrhagic areas mainly distributed in the telencephalon and diencephalon. Histopathologically, numerous veins and capillaries were filled with neoplastic lymphoid cells, accompanied by edema, hemorrhage, and thrombosis. Immunohistochemistry (IHC) for CD3, CD20, and PAX5 was performed to phenotype the neoplastic lymphocytes. IHC for CD44 and CD29 were used to investigate the pathogenetic mechanism leading to the intravascular aggregation of the neoplastic lymphocytes. The same IHC panel was applied to 8 cases of primary and metastatic canine CNS lymphoma in order to compare IVL immunoreactivity. Three IVLs were typified as T-cell, 3 as B-cell, and 4 as non-T non-B. Neoplastic lymphocytes showed marked expression of CD44 in all IVL cases, and CD29-immunolabeled cells were observed in 4 IVLs. CD44 immunoreactivity was consistent with the findings reported in human IVL, suggesting a predisposition to the formation of lymphocyte aggregates. CD29 was inconsistently immunonegative in canine IVL, confirming only partially the pathogenetic mechanism suggested for the human counterpart. PMID- 30286706 TI - Identification of an aldehyde oxidase involved in indole-3-acetic acid synthesis in Bombyx mori silk gland. AB - : Auxin is thought to be an important factor in the induction of galls by galling insects. We have previously shown that both galling and nongalling insects synthesize indole-3-acetic acid (IAA) from tryptophan (Trp) via two intermediates, indole-3-acetaldoxime (IAOx) and indole-3-acetaldehyde (IAAld). In this study, we isolated an enzyme that catalyzes the last step "IAAld -> IAA" from a silk-gland extract of Bombyx mori. The enzyme, designated "BmIAO1", contains two 2Fe-2S iron-sulfur-cluster-binding domains, an FAD-binding domain, and a molybdopterin-binding domain, which are conserved in aldehyde oxidases. BmIAO1 causes the nonenzymatic conversion of Trp to IAAld and the enzymatic conversion of IAOx to IAA, suggesting that BmIAO1 alone is responsible for IAA production in B. mori. However, a detailed comparison of pure BmIAO1 and the crude silk-gland extract suggested the presence of other enzymes involved in IAA production from Trp.

PMID- 30286707 TI - Investigating the Degree of Reliable Change Among Persons Assigned to Receive Mental Health Peer Specialist Services. AB - OBJECTIVE:: Peer specialists are individuals with mental illness and substance use disorders trained to use their experiences to help others with similar disorders. Evidence for the effectiveness of peer specialist services has been mixed in previous randomized trials using intent-to-treat analyses, possibly because of variation in the intensity of treatment delivered. This study, which was part of a larger randomized trial, assessed whether level of peer specialist engagement was associated with reliable positive change on measures of psychiatric symptoms and hope. METHODS:: The Reliable Change Index was used to compute whether veterans (N=140) achieved reliable positive change on standardized baseline-to-posttest assessments of psychiatric symptoms and hope. Logistic regression analyses were conducted to predict positive change in symptoms and hope by level of peer specialist engagement, with controls for relevant demographic factors, several baseline mental health and substance abuse measures, and service use during the study. RESULTS:: Logistic regression models showed that veterans with higher peer specialist engagement were more likely than those in a control group to show reliable positive change in psychiatric symptoms but not in hope. Compared with the control group, those with lower peer specialist engagement did not show positive change on either measure. White veterans were less likely than those from minority groups to exhibit positive change in psychiatric symptoms. CONCLUSIONS:: Results suggest that peer specialists can benefit those with mental illnesses and substance use disorders who engage in more frequent interactions. Studies are needed to further assess the circumstances under which peer specialists can be effective. PMID- 30286708 TI - Racial and Ethnic Differences in Use of State-Operated Inpatient Substance Abuse Services, 2004-2005 Versus 2010-2011. AB - OBJECTIVE:: This study examined ethnic-racial differences in referral source, length of stay, legal status, and diagnosis in state-operated substance abuse inpatient treatment in Connecticut. METHODS:: Data from 2004-2005 (N=1,484) and from 2010-2011 (N=4,529) were investigated with regression analyses. RESULTS:: At both time points, African Americans were more likely than other groups to be referred by criminal justice sources, Hispanics were more likely than whites to be referred by other sources, and whites were more likely than African Americans to have emergency-crisis admissions; length of stay was shorter for Hispanics than for whites and longer for African Americans than for whites and Hispanics; and Hispanics were less likely than other groups to have an alcohol use disorder, more likely than other groups to have a drug use disorder, and more likely than whites to receive a discharge diagnosis of a personality disorder from cluster B. CONCLUSIONS:: Targeted interventions to address racial-ethnic differences in inpatient addiction treatment are needed. PMID- 30286709 TI - Use of a Web-Based Shared Decision-Making Program: Impact on Ongoing Treatment Engagement and Antipsychotic Adherence. AB - OBJECTIVE:: The authors examined the impact of a Web-based shared decision-making application, MyCHOIS-CommonGround, on ongoing outpatient mental health treatment engagement (all users) and antipsychotic medication adherence (users with schizophrenia). METHODS:: An intervention study was conducted by comparing Medicaid-enrolled MyCHOIS-CommonGround users in 12 participating mental health clinics (N=472) with propensity score-matched adults receiving services in nonparticipating clinics (N=944). Medicaid claims were used to assess ongoing treatment engagement and antipsychotic adherence (among individuals with schizophrenia) one year prior to and after entry into the cohort. Multilevel linear models were conducted to estimate the effects of the MyCHOIS-CommonGround program over time. RESULTS:: No differences during the baseline year were found between the MyCHOIS-CommonGround group and the matched control group on demographic, diagnostic, or service use characteristics. At one-year follow-up, engagement in outpatient mental health services was significantly higher for MyCHOIS-CommonGround users than for the control group (months with a service, 8.54+/-.22 versus 6.95+/-.15; beta=1.40, p<.001). Among individuals with schizophrenia, antipsychotic medication adherence was also higher during the follow-up year among MyCHOIS-CommonGround users compared with the control group (proportion of days covered by medication, .78+/-.04 versus .69+/-.03; beta=.06, p<.01). CONCLUSIONS:: These findings provide new evidence that shared decision making tools may promote ongoing mental health treatment engagement for individuals with serious mental illness and improved antipsychotic medication adherence for those with schizophrenia. PMID- 30286710 TI - XenofilteR: computational deconvolution of mouse and human reads in tumor xenograft sequence data. AB - BACKGROUND: Mouse xenografts from (patient-derived) tumors (PDX) or tumor cell lines are widely used as models to study various biological and preclinical aspects of cancer. However, analyses of their RNA and DNA profiles are challenging, because they comprise reads not only from the grafted human cancer but also from the murine host. The reads of murine origin result in false positives in mutation analysis of DNA samples and obscure gene expression levels when sequencing RNA. However, currently available algorithms are limited and improvements in accuracy and ease of use are necessary. RESULTS: We developed the R-package XenofilteR, which separates mouse from human sequence reads based on the edit-distance between a sequence read and reference genome. To assess the accuracy of XenofilteR, we generated sequence data by in silico mixing of mouse and human DNA sequence data. These analyses revealed that XenofilteR removes > 99.9% of sequence reads of mouse origin while retaining human sequences. This allowed for mutation analysis of xenograft samples with accurate variant allele frequencies, and retrieved all non-synonymous somatic tumor mutations. CONCLUSIONS: XenofilteR accurately dissects RNA and DNA sequences from mouse and human origin, thereby outperforming currently available tools. XenofilteR is open source and available at https://github.com/PeeperLab/XenofilteR . PMID- 30286711 TI - Developmental studies provide new insights into the evolution of sense organs in Sabellariidae (Annelida). AB - BACKGROUND: Sabellarids, also known as honeycomb or sandcastle worms, when building their tubes, produce chemical signals (free fatty acids) that are responsible for larval settlement and the formation of three-dimensional aggregations. The larval palps and the dorsal hump (becoming the median organ in adults) are presumed to participate in such a substrate selection during settlement. Notably, the sabellariid median organ is an apparently unique organ among annelids that has been attributed with a sensory function and perhaps with some affinities to the nuchal organs of other polychaetes. Nevertheless, detailed investigations of this prominent character complex including ultrastructural examinations are lacking so far. RESULTS: Our comprehensive investigations provide data about the anterior sensory organs in Sabellariidae and inform about their transformation during pelagic larval development. We used a comparative approach including immunostaining with subsequent confocal laser scanning microscopy (clsm), histological sections as well as electron microscopy in a range of larval and adult stages of two sabellariid species. We find that the neuronal innervation as well as the ultrastructure of the sabellariid ciliary structures along the median organ are highly comparable with that of nuchal organs known from other polychaetes. Furthermore, the myoinhibitory protein (MIP) - a protein known to be also involved into chemo-sensation - was detected in the region of the larval median organ. Moreover, we reveal the presence of an unusual type of photoreceptor as part of the median organ in Idanthyrsus australiensis with a corrugated sensory membrane ultrastructure unlike those observed in the segmental ocelli of other polychaetes. CONCLUSIONS: We are describing for the first time the nuchal organ-like structures in different developmental stages of two species of Sabellariidae. The external morphology, neuronal innervation, developmental fate and ultrastructure of the newly-discovered median organ-based ciliary pits are comparable with the characteristics known for annelid nuchal organs and therefore indicate a homology of both sensory complexes. The presence of myoinhibitory peptide (MIP) in the respective region supports such a hypothesis and exhibits the possibility of an involvement of the entire sabellariid median organ complex, and in particular the prominent ciliated pits, in chemo-sensation. PMID- 30286712 TI - Oldest ctenodactyloid tarsals from the Eocene of China and evolution of locomotor adaptations in early rodents. AB - BACKGROUND: Tamquammys has been considered one of the basal ctenodactyloid rodents, which has been documented in the earliest to middle Eocene (~ 56.0-48.5 Ma) in China. It was the most abundant and widespread rodent genus in the Erlian Basin (Nei Mongol, China) and dominated Arshantan small-mammal faunas of that region. Here for the first time we describe the morphology of the astragalocalcaneal complex in Tamquammys robustus (larger) and T. wilsoni, and interpret it against the background of locomotor adaptations of basal Euarchontoglires (rodents, lagomorphs, tree shrews, and primates). RESULTS: The comparative morphology of the tarsal elements in Tamquammys robustus and T. wilsoni shows overall slenderness of the bones and their similarity to the tarsal elements of Rattus, a generalist species, and those of small rock squirrels (e.g. Sciurotamias). The two species differ slightly in their cursorial ability; smaller T. wilsoni shows some adaptations to climbing. The results of principal component analysis of the calcaneus and astragalus support this observation and place T. robustus in-between Rattus and ground/rock squirrel morphospace, and T. wilsoni closer to euarchontans, Tupaia and Purgatorius. CONCLUSIONS: The morphology of the tarsal elements in Tamquammys indicates a generalist rodent morphotype with no particular adaptations to arboreality. We suggest that Tamquammys as a basal ctenodactyloid is closer to the ancestral astragalocalcaneal morphology of rodents than that of more derived North American paramyines of similar age. Overall similarity in Tamquammys tarsal elements structure to Purgatorius, a basal primate, may point to the antiquity of the tarsal structure in Tamquammys and a generally unspecialized foot structure in early Euarchontoglires. PMID- 30286713 TI - GPrank: an R package for detecting dynamic elements from genome-wide time series. AB - BACKGROUND: Genome-wide high-throughput sequencing (HTS) time series experiments are a powerful tool for monitoring various genomic elements over time. They can be used to monitor, for example, gene or transcript expression with RNA sequencing (RNA-seq), DNA methylation levels with bisulfite sequencing (BS-seq), or abundances of genetic variants in populations with pooled sequencing (Pool seq). However, because of high experimental costs, the time series data sets often consist of a very limited number of time points with very few or no biological replicates, posing challenges in the data analysis. RESULTS: Here we present the GPrank R package for modelling genome-wide time series by incorporating variance information obtained during pre-processing of the HTS data using probabilistic quantification methods or from a beta-binomial model using sequencing depth. GPrank is well-suited for analysing both short and irregularly sampled time series. It is based on modelling each time series by two Gaussian process (GP) models, namely, time-dependent and time-independent GP models, and comparing the evidence provided by data under two models by computing their Bayes factor (BF). Genomic elements are then ranked by their BFs, and temporally most dynamic elements can be identified. CONCLUSIONS: Incorporating the variance information helps GPrank avoid false positives without compromising computational efficiency. Fitted models can be easily further explored in a browser. Detection and visualisation of temporally most active dynamic elements in the genome can provide a good starting point for further downstream analyses for increasing our understanding of the studied processes. PMID- 30286714 TI - Evaluating the social fitness Programme for older people with cognitive problems and their caregivers: lessons learned from a failed trial. AB - BACKGROUND: This process evaluation article describes the lessons learned from a failed trial which aimed to assess effectiveness of the tailor-made, multidisciplinary Social Fitness Programme to improve social participation of community-dwelling older people with cognitive problems (clients) and their caregivers (couples). METHODS: A process evaluation was performed to get insight in 1) the implementation of the intervention, 2) the context of intervention delivery from professionals' point of view, and 3) the potential impact of intervention delivery from participants' perspectives. Data was gathered using mixed-methods: questionnaires, focus group discussions, interviews, medical records. RESULTS: 1) Implementation. High study decline (65,3%) was mainly caused by a lack of internal motivation to increase social participation expressed by clients. 17 couples participated, however, intervention delivery was insufficient. 2) Context. Barriers during intervention delivery were most often related to client (changing needs), caregiver (increased burden) and health professional factors (delivery of integrated care lacked routine). 3) Impact Qualitative analyses revealed participants to be satisfied with intervention delivery, we were unable to capture these results through our primary outcome measure. CONCLUSIONS: This process evaluation revealed the Social Fitness study did not fit in three ways. First, framing the intervention on social participation promotion was as threatening to clients. The feeling of being unable to adequately contribute to social interactions seemed to be causing embarrassment. Second, the intervention seemed to be too complex to implement in the way it was designed. Third, there is a tension between the offering of a personalised tailor-made intervention and evaluation through a fixed study design. TRIAL REGISTRATION: The trial which is evaluated in this article (the Social Fitness study) is registered with the Dutch Trial Register (NTR), clinical trial number NTR4347 . PMID- 30286715 TI - Identification and functional characterization of intermediate-size non-coding RNAs in maize. AB - BACKGROUND: The majority of eukaryote genomes can be actively transcribed into non-coding RNAs (ncRNAs), which are functionally important in development and evolution. In the study of maize, an important crop for both humans and animals, aside from microRNAs and long non-coding RNAs, few studies have been conducted on intermediate-size ncRNAs. RESULTS: We constructed a homogenized cDNA library of 50-500 nt RNAs in the maize inbred line Chang 7-2. Sequencing revealed 169 ncRNAs, which contained 58 known and 111 novel ncRNAs (including 70 snoRNAs, 27 snRNAs, 13 unclassified ncRNAs and one tRNA). Forty of the novel ncRNAs were specific to the Panicoideae, and 24% of them are located on sense-strand of the 5' or 3' terminus of protein coding genes on chromosome. Target site analysis found that 22 snoRNAs can guide to 38 2'-O-methylation and pseudouridylation modification sites of ribosomal RNAs and small nuclear RNAs. Expression analysis showed that 43 ncRNAs exhibited significantly altered expression in different tissues or developmental stages of maize seedlings, eight ncRNAs had tissue specific expression and five ncRNAs were strictly accumulated in the early stage of leaf development. Further analysis showed that 3 of the 5 stage-specific ncRNAs (Zm-3, Zm-18, and Zm-73) can be highly induced under drought and salt stress, while one snoRNA Zm-8 can be repressed under PEG-simulated drought condition. CONCLUSIONS: We provided a genome-wide identification and functional analysis of ncRNAs with a size range of 50-500 nt in maize. 111 novel ncRNAs were cloned and 40 ncRNAs were determined to be specific to Panicoideae. 43 ncRNAs changed significantly during maize development, three ncRNAs can be strongly induced under drought and salt stress, suggesting their roles in maize stress response. This work set a foundation for further study of intermediate-size ncRNAs in maize. PMID- 30286716 TI - Expression of cotton PLATZ1 in transgenic Arabidopsis reduces sensitivity to osmotic and salt stress for germination and seedling establishment associated with modification of the abscisic acid, gibberellin, and ethylene signalling pathways. AB - BACKGROUND: Zinc-finger transcription factors play central roles in plant growth, development and abiotic stress responses. PLATZ encodes a class of plant-specific zinc-finger transcription factor. However, biological functions or physiological mechanism controlled by PLATZ are currently limited. RESULTS: GhPLATZ1 transcripts were considerably up-regulated by NaCl, mannitol, abscisic acid (ABA) and gibberellin (GA) treatments. Transgenic Arabidopsis by ectopic expression of GhPLATZ1 exhibited faster seed germination and higher seedling establishment under salt and mannitol stresses than those of wild type (WT), indicating enhanced osmotic insensitivity in GhPLATZ1 transgenic Arabidopsis. The ABA content in dry seeds of GhPLATZ1 transgenic Arabidopsis was lower than that of WT whereas the ABA content was not changed in germinating seeds under salt stress. Seed germination was faster than but the seedling establishment of transgenic Arabidopsis was similar to WT. Besides, GhPLATZ1 transgenic and WT Arabidopsis exhibited insensitivity to paclobutrazol (PAC), a GA biosynthesis inhibitor, whereas exogenous GA could eliminate the growth difference between GhPLATZ1 transgenic and WT Arabidopsis under salt stress. Moreover, exogenous 1 aminocyclopropane-1-carboxylic acid (ACC), an ethylene precursor, exerted similar effects to GA. Furthermore, ABI4 and ETO1 transcripts were significantly down regulated, whereas ACS8 was up-regulated in GhPLATZ1 transgenic Arabidopsis under salt stress. CONCLUSIONS: In conclusion, GhPLATZ1 had broad influence in responses to salt and mannitol stresses in transgenic Arabidopsis during seed germination and seedling establishment. The effect of GhPLATZ1 expression in transgenic Arabidopsis might be mediated by the ABA, GA, and ethylene pathways. Thus, this study provided new insights into the regulatory network in response to abiotic stresses in plants. PMID- 30286717 TI - Comparative evaluation of cannabinoid receptors, apelin and S100A6 protein in the heart of women of different age groups. AB - BACKGROUND: Recent studies have shown a significant role of the endocannabinoid system, apelin and S100A6 protein in the regulation of cardiovascular system functioning. The aim of the study was to compare and evaluate the distribution of cannabinoid receptors (CB1 and CB2), apelin and S100A6 protein in the heart of healthy women in different age groups. METHODS: The study was conducted on the hearts of 10 women (organ donors) without a history of cardiovascular disease, who were divided into two age groups: women older than 50 years and women under 50 years of age. Paraffin heart sections were processed by immunohistochemistry for detection of cannabinoids receptors (CB1 and CB2), apelin and S100A6 protein. RESULTS: CB1 and CB2 immunoreactivity in the cytoplasm of cardiomyocytes in the heart of women over 50 was weaker than in younger individuals. There was also strong immunoreactivity of CB1 in intercalated discs (ICDs) of the heart, only in women over 50. The presence of this receptor in this location was not found in women under 50. Apelin- and S100A6-immunoreactivity in the cardiomyocytes was stronger in older women compared to women under 50.The CB1, apelin and S100A6 immunostaining in the endothelium of myocardial vessels was weaker in women over 50 than in younger women, while intensity of CB2- immunoreaction in coronary endothelium was similar in both groups of women. The results of the study indicate the important role of endocannabinoids, apelin, and S100A6 protein in cardiac muscle function. CONCLUSION: This report might contribute to a better understanding of the role of endocannabinoid system, apelin and S100 proteins in heart function as well as shed new light on processes involved in age-related cardiomyopathy. PMID- 30286718 TI - Exploring the sensory screening experiences of nurses working in long-term care homes with residents who have dementia: a qualitative study. AB - BACKGROUND: The prevalence of vision and hearing loss is higher amongst older individuals with dementia, as well as higher in long-term care settings than in the wider community. However, the incidence of sensory impairment is underreported and often goes untreated. In this study, we aimed to understand nurses' current experiences of screening and caring for long-term care residents who have dementia and sensory impairment. METHODS: As part of a larger study on the sensory screening of long-term care residents with dementia, an environmental scan was conducted with front-line healthcare providers. We report here on the findings from the content analysis of individual, semi-structured interviews with nurses working in two long-term care homes in Southern Ontario, Canada. Twenty regulated nurses, including designated resident assessment coordinators, working full- or part-time with individuals who have dementia, participated across the two sites. All interviews were transcribed, and their contents reviewed and coded for themes by means of inductive thematic analysis. RESULTS: Following a systematic and recursive approach, three analysts identified several themes relating to: 1) the sensory screening process, 2) communication strategies, and 3) quality of life, sensory loss, and dementia. Participants reported on the strengths and limitations of screening procedures, what improvements should be made, which informal strategies are effective, and the continued professional development that is needed. CONCLUSIONS: Nurses demonstrated insight into the facilitators and barriers to effective screening and care of residents with dementia and sensory impairments, and expressed the need for further education, more suitable screening tools, and formalised accountability within the screening process for vision and hearing loss in these long-term care residents. PMID- 30286720 TI - A transdisciplinary team approach to scoping reviews: the case of pediatric polypharmacy. AB - BACKGROUND: Polypharmacy can be either beneficial or harmful to children. We conducted a scoping review to examine the concept of pediatric polypharmacy: its definition, prevalence, extent and gaps in research. In this manuscript, we report our transdisciplinary scoping review methodology. METHODS: After establishing a transdisciplinary team, we iteratively developed standard operating procedures for the study's search strategy, inclusion/exclusion criteria, screening, and data extraction. We searched eight bibliographic databases, screened abstracts and full text articles, and extracted data from included studies using standardized forms. We held regular team meetings and performed ongoing internal validity measurements to maintain consistent and quality outputs. RESULTS: With the aid of EPPI Reviewer collaborative software, our transdisciplinary team of nine members performed dual reviews of 363 included studies after dual screening of 4398 abstracts and 1082 full text articles. We achieved overall agreement of 85% and a kappa coefficient of 0.71 (95% CI 0.68 0.74) while screening full text articles. The screening and review processes required about seven hours per extracted study. The two pharmacists, an epidemiologist, a neurologist, and a librarian on the review team provided internal consultation in these key disciplines. A stakeholder group of 10 members with expertise in evidence synthesis, research implementation, pediatrics, mental health, epilepsy, pharmacoepidemiology, and pharmaceutical outcomes were periodically consulted to further characterize pediatric polypharmacy. CONCLUSIONS: A transdisciplinary approach to scoping reviews, including internal and external consultation, should be considered when addressing complex cross disciplinary questions. PMID- 30286719 TI - Rice stripe virus-derived siRNAs play different regulatory roles in rice and in the insect vector Laodelphax striatellus. AB - BACKGROUND: Most plant viruses depend on vector insects for transmission. Upon viral infection, virus-derived small interfering RNAs (vsiRNAs) can target both viral and host transcripts. Rice stripe virus (RSV) is a persistent-propagative virus transmitted by the small brown planthopper (Laodelphax striatellus, Fallen) and can cause a severe disease on rice. RESULTS: To investigate how vsiRNAs regulate gene expressions in the host plant and the insect vector, we analyzed the expression profiles of small RNAs (sRNAs) and mRNAs in RSV-infected rice and RSV-infected planthopper. We obtained 88,247 vsiRNAs in rice that were predominantly derived from the terminal regions of the RSV RNA segments, and 351,655 vsiRNAs in planthopper that displayed relatively even distributions on RSV RNA segments. 38,112 and 80,698 unique vsiRNAs were found only in rice and planthopper, respectively, while 14,006 unique vsiRNAs were found in both of them. Compared to mock-inoculated rice, 273 genes were significantly down regulated genes (DRGs) in RSV-infected rice, among which 192 (70.3%) were potential targets of vsiRNAs based on sequence complementarity. Gene ontology (GO) analysis revealed that these 192 DRGs were enriched in genes involved in kinase activity, carbohydrate binding and protein binding. Similarly, 265 DRGs were identified in RSV-infected planthoppers, among which 126 (47.5%) were potential targets of vsiRNAs. These planthopper target genes were enriched in genes that are involved in structural constituent of cuticle, serine-type endopeptidase activity, and oxidoreductase activity. CONCLUSIONS: Taken together, our results reveal that infection by the same virus can generate distinct vsiRNAs in different hosts to potentially regulate different biological processes, thus reflecting distinct virus-host interactions. PMID- 30286721 TI - Genome-wide identification and differentially expression analysis of lncRNAs in tilapia. AB - BACKGROUND: Long noncoding RNAs (LncRNAs) play important roles in fundamental biological processes. However, knowledge about the genome-wide distribution and stress-related expression of lncRNAs in tilapia is still limited. RESULTS: Genome wide identification of lncRNAs in the tilapia genome was carried out in this study using bioinformatics tools. 103 RNAseq datasets that generated in our laboratory or collected from NCBI database were analyzed. In total, 72,276 high confidence lncRNAs were identified. The averaged positive correlation coefficient (r_mean = 0.286) between overlapped lncRNA and mRNA pairs showed significant differences with the values for all lncRNA-mRNA pairs (r_mean = 0.176, z statistics = - 2.45, p value = 0.00071) and mRNA-mRNA pairs (r_mean = 0.186, z statistics = - 2.23, p value = 0.0129). Weighted correlation network analysis of the lncRNA and mRNA datasets from 12 tissues identified 21 modules and many interesting mRNA genes that clustered with lncRNAs. Overrepresentation test indicated that these mRNAs enriched in many biological processes, such as meiosis (p = 0.00164), DNA replication (p = 0.00246), metabolic process (p = 0.000838) and in molecular function, e.g., helicase activity (p = 0.000102) and catalytic activity (p = 0.0000612). Differential expression (DE) analysis identified 99 stress-related lncRNA genes and 1955 tissue-specific DE lncRNA genes. MiRNA lncRNA interaction analysis detected 72,267 lncRNAs containing motifs with sequence complementary to 458 miRNAs. CONCLUSIONS: This study provides an invaluable resource for further studies on molecular bases of lncRNAs in tilapia genomes. Further function analysis of the lncRNAs will help to elucidate their roles in regulating stress-related adaptation in tilapia. PMID- 30286722 TI - Estimating bacteria diversity in different organs of nine species of mosquito by next generation sequencing. AB - BACKGROUND: Symbiosis in insects is accumulating significant amount of studies: the description of a wide array of mutualistic associations across the evolutionary history of insects suggests that resident microbiota acts as a driving force by affecting several aspects of hosts biology. Among arthropods, mosquito midgut microbiota has been largely investigated, providing crucial insights on the role and implications of host-symbiont relationships. However, limited amount of studies addressed their efforts on the investigation of microbiota colonizing salivary glands and reproductive tracts, crucial organs for pathogen invasion and vertical transmission of symbiotic microorganisms. Using 16S rRNA gene sequencing-based approach, we analysed the microbiota of gut, salivary glands and reproductive tracts of several mosquito species, representing some of the main vectors of diseases, aiming at describing the dynamics of bacterial communities within the individual. RESULTS: We identified a shared core microbiota between different mosquito species, although interesting inter- and intra-species differences were detected. Additionally, our results showed deep divergences between genera, underlining microbiota specificity and adaptation to their host. CONCLUSIONS: The comprehensive landscape of the bacterial microbiota components may ultimately provide crucial insights and novel targets for possible application of symbionts in innovative strategies for the control of vector borne diseases, globally named Symbiotic Control (SC), and suggesting that the holobiont of different mosquito species may significantly vary. Moreover, mosquito species are characterized by distinctive microbiota in different organs, likely reflecting different functions and/or adaptation processes. PMID- 30286723 TI - ROK study-C (Rainbow of KIBOU study-colorectum): a colorectal cancer survivor cohort study on food, nutrition, physical activity, psychosocial factors and its influences on colorectal cancer recurrence, survival and quality of life in Japan. AB - BACKGROUND: Many studies have shown that lifestyle factors such as diet, physical activity are related to the incidence of cancer. However, there are few studies on the association between lifestyle factors and cancer prognosis. To investigate the influence of lifestyle factors and psychosocial factors on prognosis, we started a prospective study of women with breast cancer, the Rainbow of KIBOU study-Breast (ROK Study-B) in 2007. As of February 2018, more than 6300 women have been enrolled, thus making this one of the world's largest cancer patient cohort studies. Based on the know-how obtained from this study, we started another new cohort study for colorectal cancer patient (ROK Study-C). METHODS: The ROK Study-C is a prospective observational study for colorectal cancer survivors at the National Cancer Center Hospital. Participants fill in several self-administrated questionnaires about lifestyle, psychosocial factors (including posttraumatic growth and benefit finding, support), and quality of life (QOL) 5 times in total: at diagnosis, 3 and 6 months, 1 and 5 years after surgery. CT-scans will be collected to assess body composition and obesity. We also use blood and cancer tissue from the Biobank. The primary endpoint is disease-free survival. The secondary endpoints are overall survival and health related QOL. The planned sample size is 2000 and the follow-up period is 5 years after the last enrollment. DISCUSSION: Recruitment began in December 2015 and the study is still ongoing. The ROK Study-C will contribute to improvements in patient prognosis and yield important evidence for colorectal cancer survivorship. PMID- 30286724 TI - Dynapenia could predict chemotherapy-induced dose-limiting neurotoxicity in digestive cancer patients. AB - BACKGROUND: FIGHTDIGO study showed the feasibility and acceptability of handgrip strength (HGS) measure in routine in 201 consecutive patients with digestive cancer treated with ambulatory chemotherapy. The present study focuses on the second aim of FIGHTDIGO study: the relationships between pre-therapeutic dynapenia and chemotherapy-induced Dose-Limiting Toxicities (DLT). METHODS: In this ancillary prospective study, DLT were analyzed in a sub-group of 45 chemotherapy-naive patients. Two bilateral consecutive measures of HGS were performed with a Jamar dynamometer before the first cycle of chemotherapy. Dynapenia was defined as HGS < 30 kg (men) and < 20 kg (women). DLT and/or Dose Limiting Neurotoxicity (DLN) were defined as any toxicity leading to dose reduction, treatment delays or permanent treatment discontinuation. RESULTS: Two thirds of chemotherapies were potentially neurotoxic (n = 31 [68.7%]) and 22 patients (48.9%) received FOLFOX (5FU, leucovorin plus oxaliplatin) regimen chemotherapy. Eleven patients (24.4%) had pre-therapeutic dynapenia. The median number of chemotherapy cycles was 10 with a median follow-up of 167 days. Twenty two patients experienced DLT (48.9%). There was no significant association between pre-therapeutic dynapenia and DLT (p = 0.62). Nineteen patients (42.2%) experienced DLN. In multivariate analysis, dynapenia and tumoral location (stomach, biliary tract or small intestine) were independent risk factors for DLN (HR = 3.5 [1.3; 9.8]; p = 0.02 and HR = 3.6 [1.3; 10.0]; p = 0.01, respectively). CONCLUSIONS: Digestive cancer patients with pre-therapeutic dynapenia seemed to experience more DLN. HGS routine measurement may be a way to screen patients with frailty marker (dynapenia) who would require chemotherapy dose adjustment and adapted physical activity programs. TRIAL REGISTRATION: NCT02797197 June 13, 2016 retrospectively registered. PMID- 30286725 TI - Molecular characteristics of extended-spectrum beta-lactamase-producing Escherichia coli isolated from the rivers and lakes in Northwest China. AB - BACKGROUND: Extended-spectrum beta-lactamases (ESBLs)-producing Escherichia coli (E. coli) isolates in environment water become progressively a potential threat to public health, while the detailed information about the ESBL-producing E. coli isolates in the rivers and lakes in Northwest China is scarce. In the present study, it was aimed to characterize the ESBL-producing E. coli isolated from the surface waters in Northwest China. RESULTS: A total of 2686 E. coli isolates were obtained from eleven rivers and lakes in Northwest China to screen for ESBL producers. Seventy-six (2.8%) isolates were classified as ESBL producers, and phylogenic groups D and A accounted for 59.2% of the ESBL producers. CTX-Ms were the predominant ESBLs genotype, and they were represented by seven blaCTX-M subtypes. blaCTX-M-14 was the most prevalent specific CTX-M gene, followed by blaCTX-M-9, blaCTX-M-123, blaCTX-M-15, blaCTX-M-27, blaCTX-M-1 and blaCTX-M-65. Moreover, 54 of the 76 ESBL producers carried at least one plasmid-mediated quinolone resistance (PMQR) gene, and aac(6')-Ib-cr was predominant. The overall occurrence of virulence factors ranged from 1.3% (eae) to 48.7% (traT). Thirty seven sequence types (STs) were confirmed among the 76 ESBL producers, and the predominant was ST10, which was represented by 10 isolates; importantly, clone B2 ST131, associated with severe infections in humans and animals, was detected three times. CONCLUSION: The prevalence of ESBL-producing E. coli from the rivers and lakes in Northwest China was low (2.8%), and the extraintestinal pathogenic E. coli (ExPEC) pathotype was the most commonly detected on the basis of the virulence factor profiles. 76.3% of ESBL producers harbored more than one beta lactamase gene, and blaCTX-M-14 was the predominant genotype. Notably, one ST131 isolate from Gaogan Canal simultaneously harbored blaCTX-M-9, blaCTX-M-15, blaCTX M-123, blaKPC-2, blaNDM-1, blaOXA-2 as well as the PMQR genes qnrA, qnrS and aac(6')-Ib-cr. PMID- 30286726 TI - Impact of the 10-valent pneumococcal conjugate vaccine on antimicrobial prescriptions in young children: a whole population study. AB - BACKGROUND: Antimicrobial resistance is a public-health threat and antimicrobial consumption is the main contributor. The ten-valent pneumococcal conjugate vaccine (PHiD-CV10) was introduced into the Icelandic vaccination program in 2011. The aim was to estimate the vaccine impact of PHiD-CV10 on outpatient antimicrobial prescriptions in children. METHODS: Eleven Icelandic birth-cohorts (2005-2015) were followed from birth until three years of age or to the end of the study period (December 31, 2016). Birth-cohorts were grouped as vaccine non eligible (VNEC, 2005-2010) or vaccine eligible (VEC, 2011-2015). Data on primary care visits for respiratory infections and antimicrobial prescriptions were extracted from two national registers. Using national identification numbers, prescriptions were linked to physician visits if filled within three days of the visit. Incidence rates and incidence rate ratios between VNEC and VEC were calculated. An Andersen-Gill model was used to model the individual level data, accounting for repeated events and censoring. Vaccine impact was calculated as (1 - Hazard Ratio) * 100%. RESULTS: Included were 53,510 children who contributed 151,992 person-years of follow-up and filled 231,660 antimicrobial prescriptions. The incidence rate was significantly lower in the VEC compared to the VNEC, 144.5 and 157.2 prescriptions per 100 person-years respectively (IRR 0.92, 95%CI 0.91 0.93). Children in VEC were more likely to have filled zero (IRR 1.16 (95%CI 1.10 1.23) and 1-4 (IRR 1.08 95%CI 1.06-1.11) prescriptions compared to children in VNEC. The vaccine impact of PHiD-CV10 against all-cause antimicrobial prescriptions was 5.8% (95%CI 1.6-9.8%).When only considering acute otitis media associated prescriptions, the vaccine impact was 21.8% (95%CI 11.5-30.9%). CONCLUSION: The introduction of PHiD-CV10 lead to reduced antimicrobial use in children, mainly by reducing acute otitis media episodes. This intervention therefore reduces both disease burden and could slow the spread of antimicrobial resistance. PMID- 30286727 TI - Disability, quality of life and all-cause mortality in older Mexican adults: association with multimorbidity and frailty. AB - BACKGROUND: Multimorbidity and frailty are relevant conditions among older adult population. There is growing evidence about their association with poor health outcomes like disability, worst quality of life, and death. Nonetheless, the independent associations of both conditions have been studied, and few evidence exists about an interaction between them. Our aims were to assess the association of frailty and multimorbidity with the disability, quality of life and all-cause mortality as well as to analyze a potential interaction between these conditions. METHODS: Analytical samples included 1410 respondents for disability and quality of life, and 1792 for mortality. We performed a longitudinal analysis with older Mexican adults aged 50, using data collected from the WHO's Study on global AGEing and Adult Health Waves 1 and 2. Disability was measured using the World Health Organization Disability Assessment Schedule (WHODAS 2.0), and quality of life using the WHOQOL (WHO Quality of Life) instrument. All-cause mortality was determined by reviewing death certificates. Associations of frailty and multimorbidity with disability, quality of life and mortality were estimated using linear regression and Cox proportional hazards models. RESULTS: Multimorbidity assessed through three patterns (cardiopulmonary, vascular metabolic, and mental-musculoskeletal) was associated with the three outcomes in this study. Cardiopulmonary and mental-musculoskeletal patterns increased the WHODAS mean score (beta = 5.05; p < 0.01 and beta = 5.10; p < 0.01, respectively) and decreased WHOQOL score (beta = - 1.81; p < 0.01 and beta = - 2.99; p < 0.01, respectively). Vascular-metabolic was associated with mortality (HR = 1.47; p = 0.04), disability (beta = 3.27; p < 0.01) and quality of life (beta = - 1.30; p = 0.02). Frailty was associated with mortality (pre-frail: HR = 1.48; p = 0.02 and frail: HR = 1.68; p = 0.03), disability (pre-frail: beta = 5.02; p < 0.01; frail: beta = 13.29; p < 0.01) and quality of life (pre-frail: beta = - 2.23; p < 0.01; frail: beta = - 4.38; p < 0.01). Interaction terms of frailty and multimorbidity were not statistically significant. CONCLUSIONS: Multimorbidity and frailty are important predictors of poor health outcomes. These results highlight the importance of carrying out health promotion and prevention actions as well as specific interventions aimed at older adults who suffer from multimorbidity and frailty, in such a way that deleterious effects on health can be avoided. PMID- 30286728 TI - SoLAT (Sorafenib Lenvatinib alternating treatment): a new treatment protocol with alternating Sorafenib and Lenvatinib for refractory thyroid Cancer. AB - BACKGROUND: In the last decade, several tyrosine kinase inhibitors (TKIs), which disrupt pathways involved in the proliferation and tumorigenesis of thyroid cancer, have been extensively studied. Two different TKIs, lenvatinib and sorafenib, were recently approved by both the US FDA and European Medicine Agency. Until date, the duration of the TKI response is not sufficient and resistance eventually occurs. The goal of this study was to investigate a new treatment protocol, SoLAT, using sorafenib and lenvatinib alternatively on refractory thyroid cancer. METHODS: Patient-derived aggressive papillary thyroid cancer (PTC) cell lines from patients with biochemical and histologically proven aggressive RAI-refractory papillary thyroid cancer were exposed to sorafenib and lenvatinib alternatively. Human thyroid cancer cell xenografts were obtained by injecting patient-derived aggressive PTC cell lines into the flank of female BALB/c nude mice. Tumor-bearing mice were treated with sorafenib and lenvatinib alternatively. Cell viability assay, immunofluorescence analysis, confocal imaging, immunoblot analysis, flow cytometry analysis of cell cycle and a tube formation assay were performed. RESULTS: SoLAT was more effective for advanced PTC cell lines than individual treatment. Immunoblot analysis showed that SoLAT markedly increased levels of cell cycle inhibitors (p53 and p21), and pro apoptotic factors (Apaf-1 and cleaved caspase 3) and decreased levels of positive cell cycle regulators (cyclin D1, CDK4, CDK6) and anti-apoptotic factors (p NFkappaB, Bcl-2). Increased sub-G0/G1 population was observed in the SoLAT group, leading to apoptosis, cell cycle arrest, and strong inhibition of advanced PTC cell viability. SoLAT reduced the level of EMT markers such as vimentin, E cadherin, Snail and Zeb1 by FGFR inhibition. In the xenograft model, individual treatment with sorafenib or lenvatinib did not markedly suppress patient-derived aggressive PTC cell xenograft tumors, whereas SoLAT significantly suppressed the proliferation of these tumors. CONCLUSIONS: SoLAT was more effective than individual treatment with sorafenib or lenvatinib in inhibiting PTC progression by inducing cell cycle arrest. Studies using both in vitro cell culture and an in vivo xenograft model provided evidence of tumor shrinkage with SoLAT. We suggest that these effects may be due to reduced EMT-mediated drug resistance in the aggressive PTC model. PMID- 30286729 TI - Uc.416 + A promotes epithelial-to-mesenchymal transition through miR-153 in renal cell carcinoma. AB - BACKGROUND: The transcribed ultraconserved regions (T-UCRs) are a novel class of non-coding RNAs that are absolutely conserved across species and are involved in carcinogenesis in some cancers. However, the expression and biological role of T UCRs in renal cell carcinoma (RCC) remain poorly understood. This study aimed to examine the expression and functional role of Uc.416 + A and analyze the association between Uc.416 + A and epithelial-to-mesenchymal transition in RCC. METHODS: Expression of Uc.416 + A in 35 RCC tissues, corresponding normal kidney tissues and 13 types of normal tissue samples was determined by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). We performed a cell growth and migration assay in RCC cell line 786-O transfected with negative control and siRNA for Uc.416 + A. We evaluated the relation between Uc.416 + A and miR-153, which has a complimentary site of Uc.416 + A. RESULTS: qRT-PCR analysis revealed that the expression of Uc.416 + A was higher in RCC tissues than that in corresponding normal kidney tissues. Inhibition of Uc.416 + A reduced cell growth and cell migration activity. There was an inverse correlation between Uc.416 + A and miR-153. Western blot analysis showed Uc.416 + A modulated E-cadherin, vimentin and snail. The expression of Uc.416 + A was positively associated with the expression of SNAI1, VIM and inversely associated with the expression of CDH1. CONCLUSIONS: The expression of Uc.416 + A was upregulated in RCC and especially in RCC tissues with sarcomatoid change. Uc.416 + A promoted epithelial-to-mesenchymal transition through miR-153. These results suggest that Uc.416 + A may be a promising therapeutic target. PMID- 30286730 TI - High cut-off membrane for in-vivo dialysis of free plasma hemoglobin in a patient with massive hemolysis. AB - BACKGROUND: The possibility of clearing Cell-free Plasma Hemoglobin (CPH) from human plasma may appear attractive, especially when considering the noxious effects that CPH has on the immune function and the renal damage caused by its filtration. The existence of the so-called High Cut-Off (HCO) filters, possessing pores as big as 60 kDa, could potentially allow the clearance of the alphabeta dimers (31.3 kDa), the form in which the alpha2beta2 hemoglobin tetramers (62.6 kDa) physiologically dissociate in plasma. We present herein the first reported case in which such an attempt was made. CASE PRESENTATION: The patient was a 51 year-old man with hemolytic crisis due to glucose-6-phosphate dehydrogenase deficiency, further complicated by pigment-induced nephropathy. He underwent a 48 h CVVHD session, in which a HCO filter was used. The Sieving Coefficient (SC) for CPH was initially 0.08 and decreased to 0.02 after 24 h. This unexpected low SC was due to the initial high concentration of CPH (4.24 g/L). At such concentrations, the alpha2beta2 tetramer poorly dissociates into the alphabeta dimer; but increases exponentially at concentrations lower than 1 g/L. CONCLUSIONS: Clearance of CPH through a HCO filter is technically feasible but its performance markedly relies on the initial concentration of CPH. Critically ill patients with smoldering hemolysis, as it happens during septic shock or ECMO treatment, may benefit the most from the use of this membrane in order to clear CPH. PMID- 30286731 TI - Development of membranoproliferative glomerulonephritis-like glomerulopathy in a patient with neutrophilia resulting from endogenous granulocyte-colony stimulating factor overproduction: a case report. AB - BACKGROUND: The pathophysiologic role of exogenous granulocyte-colony stimulating factor (G-CSF) administration is reportedly linked to the progression of glomerulonephritis. However, the relationship between endogenous G-CSF overproduction and the progression of glomerulopathy has not been well investigated. CASE PRESENTATION: A 76-year-old woman presented with neutrophilia at a medical check-up and thorough examination revealed a high level of serum G CSF. She subsequently developed mild renal dysfunction and proteinuria. Her renal biopsy showed lobulation of the glomeruli with mesangial proliferation and glomerular capillary walls with a double contour but no immune complex deposition, suggesting membranoproliferative glomerulonephritis-like glomerulopathy. Thereafter, her proteinuria levels fluctuated in parallel with the changes in her blood neutrophil count and finally reduced considerably in association with her decreased neutrophil count. CONCLUSIONS: The unique features of this case suggest that endogenous overproduction of G-CSF could play an important role in the pathogenesis of active glomerulonephritis. PMID- 30286732 TI - Cerebral infarction associated with benign mucin-producing adenomyosis: report of two cases. AB - BACKGROUND: Cerebral infarction associated with a malignant tumor is widely recognized as Trousseau syndrome. In contrast, few cases of cerebral infarction associated with benign tumors have been reported. We present two cases of embolic stroke that seemed to be caused by mucin-producing adenomyosis. CASE PRESENTATION: The patients were women aged 42 and 50 years old. Both patients developed right hemiparesis and aphasia, and cerebral infarctions were detected in the left cerebral hemisphere. There were no other abnormal findings, except for elevation of CA125 and D-dimer. Trousseau syndrome was suspected in both cases, but whole body examinations did not reveal any malignant tumors. However, uterine adenomyosis was detected in both patients. CONCLUSIONS: From our findings and a review of the literature, both mucin-producing malignant tumors and mucin producing benign tumors such as adenomyosis may cause hypercoagulability and cerebral infarction. This mechanism should be considered in a case of a young to middle-aged woman with embolic stroke of an undetermined origin. PMID- 30286733 TI - Patients' quality of life during active cancer treatment: a qualitative study. AB - BACKGROUND: Patients' quality of life has become a major objective of care in oncology. At the same time, it has become the object of increasing interest by researchers, working with both quantitative and qualitative methods. Progress in oncology has enabled more patients to survive longer, so that cancer is increasingly often a chronic disease that requires long-term treatment that can have negative effects on patients' quality of daily life. Nonetheless, no qualitative study has explored what patients report affects their quality of daily life during the treatment period. This study is intended to fill this gap. METHODS: We conducted a multicenter qualitative study based on 30 semi-structured interviews. Participants, purposively selected until data saturation, had diverse types of cancer and had started treatment at least 6 months before interview. Data were examined by thematic analysis. RESULTS: Our analysis found two themes: (1) what negatively affected for patient's quality of daily life during the treatment period, a question to which patients responded by talking only about the side effects of treatment; and (2) what positively affected their quality of daily life during the treatment period with three sub-themes: (i) The interest in having -investing in - a support object that can be defined as an object, a relationship or an activity particularly invested by the patients which makes them feel good and makes the cancer and its treatment bearable, (ii)The subjective perception of the efficacy of the antitumor treatment and (iii) the positive effects of relationships, with friends and family, and also with their physician. CONCLUSIONS: Patients must be involved in their care if they are to be able to bear their course of treatment and find ways to endure the difficult experience of cancer care. The support object represents an important therapeutic lever that can be used by their oncologists. They should be interested in their support objects, in order to support the patients in this investment and to help them to maintain it throughout the health care pathway. Furthermore, showing interest in this topic, important to the patient, could improve the physician patient relation without using up very much of the physician's time. PMID- 30286735 TI - The landscape of vaccines in China: history, classification, supply, and price. AB - BACKGROUND: Vaccine regulation in China meets World Health Organization standards, but China's vaccine industry and immunization program have some characteristics that differ from other countries. We described the history, classification, supply and prices of vaccines available and used in China, compared with high-and middle-incomes countries to illustrate the development of Chinese vaccine industry and immunization program. METHODS: Immunization policy documents were obtained from the State Council and the National Health and Family Planning Commission (NHFPC). Numbers of doses of vaccines released in China were obtained from the Biologicals Lot Release Program of the National Institutes for Food and Drug Control (NIFDC). Vaccine prices were obtained from Chinese Central Government Procurement (CCGP). International data were collected from US CDC, Public Health England, European CDC, WHO, and UNICEF. RESULTS: Between 2007 and 2015, the annual supply of vaccines in China ranged between 666 million and 1,190 million doses, with most doses produced domestically. The government's Expanded Program on Immunization (EPI) prevents 12 vaccine preventable diseases (VPD) through routine immunization. China produces vaccines that are in common use globally; however, the number of routinely-prevented diseases is fewer than in high- and middle-income countries. Contract prices for program (EPI) vaccines ranged from 0.1 to 5.7 US dollars per dose - similar to UNICEF prices. Contract prices for private-market vaccines ranged from 2.4 to 102.9 US dollars per dose - often higher than prices for comparable US, European, and UNICEF vaccines. CONCLUSION: China is a well-regulated producer of vaccines, but some vaccines that are important globally are not included in China's EPI system in China. Sustained and coordinated effort will be required to bring Chinese vaccine industry and EPI into an era of global leadership. PMID- 30286734 TI - Women suffer more from disrespectful and abusive care than from the labour pain itself: a qualitative study from Women's perspective. AB - BACKGROUND: Utilization of institutional delivery services could be hampered by women's experience of disrespectful and abusive care during childbirth. However, such experiences are not well documented and taken into consideration id planning maternal health services in many developing countries. The aim of this study was to describe women's experience of disrespect and abuse during giving birth at health facilities in northern Ethiopia. METHODS: A qualitative phenomenological study was conducted in Tigray, Ethiopia. Focus group discussions (FGDs) with primipara and multipara women were conducted to collect the necessary information. All study participants had their last delivery at a health facility in the year preceding the study. A semi-structured discussion guide was used to elicit discussion. Discussions were audio recorded and transcribed verbatim in the local language and then translated to English. Data were analyzed using thematic analysis approach assisted by the Open Code qualitative data management software. RESULTS: The study participants described disrespect and abuse as serious obstacles to utilization of maternal health services. Women reported experiencing feelings of being infantilized, losing self-control, being overlooked, being informed bad news without proper preparation, repeated examination without being properly communicated/informed, disallow companions, and left unattended during labor. Facility related issues include women's perception of incompetence of professionals attending delivery, unhygienic facilities, and unavailability of basic supplies. CONCLUSION: Women consider health facilities not fully prepared to provide respectful maternal care. Sustainable increase in institutional delivery requires ensuring quality, compassionate and caring services in all health facilities. PMID- 30286736 TI - Isolated optic neuritis with a concurrent abnormal trigeminal nucleus on imaging: case report of a rare complication of herpes zoster ophthalmicus. AB - BACKGROUND: Herpes zoster ophthalmicus (HZO) is an inflammation related to reactivation of the latent varicella zoster virus (VZV), involving the ophthalmic branch of the trigeminal nerve. Optic neuritis (ON), a rare ocular complication following HZO, has been reported in 1.9% of HZO-affected eyes. Most previous cases occurred simultaneously with other ocular complications, especially orbital apex syndrome. Moreover, detailed magnetic resonance imaging (MRI) with diffusion weighted imaging of the optic nerve and trigeminal nucleus in HZO-related ON has been rarely reported. We report a case of postherpetic isolated ON with a concurrent abnormal trigeminal nucleus on imaging. CASE PRESENTATION: A healthy 58-year-old female presented with sudden painful visual loss in her right eye for 2 days. Four weeks before the presentation, her right eye was diagnosed with HZO, and she received intravenous acyclovir for 10 days. Ophthalmic examination revealed a visual acuity of light perception and 20/20 in the right and left eyes, respectively. A relative afferent pupillary defect was present in the right eye. Neurological examination was significant for hypoesthesia in the area of the HZO. A clinical diagnosis of HZO-related right retrobulbar ON was made, and other causes of atypical ON were excluded. MRI showed enhancement and restricted diffusion of the right-sided optic nerve with linear hyperintense T2 of the right sided spinal trigeminal nucleus and tract (STNT) along the brainstem. She received 14 days of intravenous acyclovir and 5 days of methylprednisolone. Both were switched to an oral route for 2 months. After the completion of treatment, the visual acuity was counting fingers and 20/20 in the right eye and left eye, respectively. Stable brainstem STNT abnormalities and resolution of ON were found radiologically. CONCLUSIONS: Isolated ON is a rare ocular complication following HZO. An abnormal high signal of STNT on a T2 weighted image may be present, which may be a clue for VZV-associated complications, such as HZO-related ON, especially in cases lacking an obvious history of HZO or other concomitant ocular complications. Prompt treatment with both acyclovir and corticosteroids should be started. Restricted diffusion of the optic nerve may be a predictor for poor visual recovery.

AB - In this comment, we highlight that the IDUA pathogenic variants 704ins5 and c.613_617dupTGCTC are the same, but have different names depending on the nomenclature guideline used. Therefore, the frequency of this variant is 17.6% of alleles in Korean patients. This commentary stresses the importance of proper variant annotation and the use of guidelines when describing or reviewing mutations. PMID- 30286737 TI - Acceptability of HIV self-testing to support pre-exposure prophylaxis among female sex workers in Uganda and Zambia: results from two randomized controlled trials. AB - BACKGROUND: HIV pre-exposure prophylaxis (PrEP) is highly effective for prevention of HIV acquisition, but requires HIV testing at regular intervals. Female sex workers (FSWs) are a priority population for HIV prevention interventions in many settings, but face barriers to accessing healthcare. Here, we assessed the acceptability of HIV self-testing for regular HIV testing during PrEP implementation among FSWs participating in a randomized controlled trial of HIV self-testing delivery models. METHODS: We used data from two HIV self-testing randomized controlled trials with identical protocols in Zambia and in Uganda. From September-October 2016, participants were randomized in groups to: (1) direct delivery of an HIV self-test, (2) delivery of a coupon, exchangeable for an HIV self-test at nearby health clinics, or (3) standard HIV testing services. Participants completed assessments at baseline and 4 weeks. Participants reporting their last HIV test was negative were asked about their interest in various PrEP modalities and their HIV testing preferences. We used mixed effects logistic regression models to measure differences in outcomes across randomization arms at four weeks. RESULTS: At 4 weeks, 633 participants in Zambia and 749 participants in Uganda reported testing negative at their last HIV test. The majority of participants in both studies were "very interested" in daily oral PrEP (91% Zambia; 66% Uganda) and preferred HIV self-testing to standard testing services while on PrEP (87% Zambia; 82% Uganda). Participants in the HIV self testing intervention arms more often reported preference for HIV self-testing compared to standard testing services to support PrEP in both Zambia (P = 0.002) and Uganda (P < 0.001). CONCLUSION: PrEP implementation programs for FSW could consider inclusion of HIV self-testing to reduce the clinic-based HIV testing burden.

AB - BACKGROUND: To develop a deep neural network able to differentiate glaucoma from non-glaucoma visual fields based on visual filed (VF) test results, we collected VF tests from 3 different ophthalmic centers in mainland China. METHODS: Visual fields obtained by both Humphrey 30-2 and 24-2 tests were collected. Reliability criteria were established as fixation losses less than 2/13, false positive and false negative rates of less than 15%. RESULTS: We split a total of 4012 PD images from 1352 patients into two sets, 3712 for training and another 300 for validation. There is no significant difference between left to right ratio (P = 0.6211), while age (P = 0.0022), VFI (P = 0.0001), MD (P = 0.0039) and PSD (P = 0.0001) exhibited obvious statistical differences. On the validation set of 300 VFs, CNN achieves the accuracy of 0.876, while the specificity and sensitivity are 0.826 and 0.932, respectively. For ophthalmologists, the average accuracies are 0.607, 0.585 and 0.626 for resident ophthalmologists, attending ophthalmologists and glaucoma experts, respectively. AGIS and GSS2 achieved accuracy of 0.459 and 0.523 respectively. Three traditional machine learning algorithms, namely support vector machine (SVM), random forest (RF), and k nearest neighbor (k-NN) were also implemented and evaluated in the experiments, which achieved accuracy of 0.670, 0.644, and 0.591 respectively. CONCLUSIONS: Our algorithm based on CNN has achieved higher accuracy compared to human ophthalmologists and traditional rules (AGIS and GSS2) in differentiation of glaucoma and non-glaucoma VFs.

AB - BACKGROUND: Oligometastases refer to a state of disease where cancer has spread beyond the primary site, but is not yet widely metastatic, often defined as 1-3 or 1-5 metastases in number. Stereotactic ablative radiotherapy (SABR) is an emerging radiotherapy technique to treat oligometastases that require further prospective population-based toxicity estimates. METHODS: This is a non randomized phase II trial where all participants will receive experimental SABR treatment to all sites of newly diagnosed or progressing oligometastatic disease. We will accrue 200 patients to assess toxicity associated with this experimental treatment. The study was powered to give a 95% confidence on the risk of late grade 4 toxicity, anticipating a < 5% rate of grade 4 toxicity. DISCUSSION: SABR treatment of oligometastases is occurring off-trial at a high rate, without sufficient evidence of its efficacy or toxicity. This trial will provide necessary toxicity data in a population-based cohort, using standardized doses and organ at risk constraints, while we await data on efficacy from randomized phase III trials. TRIAL REGISTRATION: Registered through clinicaltrials.gov NCT02933242 on October 14, 2016 prospectively before patient accrual. PMID- 30286742 TI - Introduction of safety and quality standards for private health care providers: a case-study from the Republic of Srpska, Bosnia and Herzegovina. AB - BACKGROUND: Regulation of private health care providers (PHPs) in middle-income countries can be challenging. Mandatory safety and quality standards for PHPs have been in place in the Republic of Srpska since 2012, but not all PHPs have adopted them yet. Adoption rates have differed among different types of providers. We studied three predominant types of PHPs to determine why the rate of adoption of the standards varies among them. METHODS: This study used a mixed methods approach, which allowed the integration of both quantitative and qualitative data, to develop an explanatory case study. The case study covered three types of private PHPs: pharmacies, dental practices and specialist practices. Primary data were collected through face-to-face semi-structured in depth interviews and a self-administered postal survey of private health care providers. Our study's theoretical framework was based on the diffusion of innovation theory. RESULTS: The rate of adoption of mandatory standards varied among different types of PHP mainly due to four factors: (1) level of concern about negative financial consequences, such as the risk of fines or of losing contracts with the Health Insurance Fund of the Republic of Srpska; (2) availability of information on the standards and implementation process; (3) level of the relevant professional association's support for the introduction of standards; and (4) provider's perceptions of the relevant health chamber's attitude toward the standards. Opinions conveyed to PHPs by peers slightly negatively influenced adoption of the standards at the attitude-forming stage. Perceived gains in professional status did not have a major influence on the decision to adopt standards. All three types of PHPs perceived the same disadvantages of the introduction of safety and quality standards: associated expense, increased administrative burden and disruption of service provision. CONCLUSIONS: When introducing mandatory quality and safety standards for PHPs, national health authorities need to: ensure adequate availability of information on the relative advantages of adhering to standards; support the introduction of standards with relevant incentives and penalties; and work in partnership with relevant professional associations and health chambers to get their buy-in for regulation of quality and safety of health services. PMID- 30286741 TI - Drug-resistant Enterobacteriaceae colonization is associated with healthcare utilization and antimicrobial use among inpatients in Pune, India. AB - BACKGROUND: Healthcare exposure may increase drug-resistant Enterobacteriaceae colonization risk. Nascent antimicrobial stewardship efforts in low- and middle income countries require setting-specific data. We aimed to evaluate risk factors for inpatient drug resistant Enterobacteriaceae colonization in a resource limited setting in India. METHODS: Patients age >= 6 months admitted with >=24 h of fever to a tertiary hospital in Pune, India were enrolled in a prospective cohort. Perirectal swabs, collected on admission and hospitalization day 3 or 4, were cultured in vancomycin- and ceftriaxone-impregnated media to assess for ceftriaxone-resistant Enterobacteriaceae (CTRE) and carbapenem-resistant Enterobacteriaceae (CPRE). Multivariable analyses assessed risk factors for drug resistant Enterobacteriaceae colonization among participants without admission colonization. RESULTS: Admission perirectal swabs were collected on 897 participants; 87 (10%) had CTRE and 14 (1.6%) had CPRE colonization. Admission CTRE colonization was associated with recent healthcare contact (p < 0.01). Follow-up samples were collected from 620 participants, 67 (11%) had CTRE and 21 (3.4%) had CPRE colonization. Among 561 participants without enrollment CTRE colonization, 49 (9%) participants were colonized with CTRE at follow-up. Detection of CTRE colonization among participants not colonized with CTRE at admission was independently associated with empiric third generation cephalosporin treatment (adjusted odds ratio [OR] 2.9, 95% CI 1.5-5.8). Follow-up transition to CPRE colonization detection was associated with ICU admission (OR 3.0, 95% CI 1.0-8.5). CONCLUSIONS: Patients who receive empiric third generation cephalosporins and are admitted to the ICU rapidly develop detectable CTRE and CPRE colonization. Improved antimicrobial stewardship and infection control measures are urgently needed upon hospital admission. PMID- 30286743 TI - Identifying the prevalence and predictors of suicidal behaviours for indigenous males in custody. AB - BACKGROUND: High rates of suicidal behaviours among Indigenous Australians have been documented. Justice-involved individuals are also at a higher risk for engaging in suicidal behaviours. This study sought to ascertain the prevalence and correlates of suicidal behaviours for 107 Indigenous adult males in custody in Victoria, Australia. METHODS: Participants undertook a structured interview comprising a psychiatric assessment. Information on suicidal behaviours (ideation and attempts), socio-demographics, environmental stressors, negative life events and mental health was obtained. RESULTS: A high proportion of Indigenous males in custody experienced lifetime suicidal ideation (63.7%) and over one-half had attempted suicide (54.5%). A smaller, yet significant number of participants experienced ideation over the past 12 months (27.9%). Having a loved one pass away within the past 12 months predicted recent ideation; lifetime ideation and a diagnosis of Post-Traumatic Stress Disorder predicted a lifetime suicide attempt. CONCLUSIONS: The prevalence of suicidal behaviours among Indigenous people in custody is remarkably high. Correlates of suicidal behaviours for Indigenous people in custody in this study likely manifest in the community, denoting an urgent public health response. Prevention must begin in communities at-risk for suicidal behaviours. The development of low intensity mental health service infrastructure in communities to promote awareness and provide accessible, least restrictive support and treatment is necessary. Correctional institutions must also continue to improve custodial suicide prevention and management initiatives. PMID- 30286744 TI - Relation between health literacy, self-care and adherence to treatment with oral anticoagulants in adults: a narrative systematic review. AB - BACKGROUND: Oral anticoagulants (OAC) are widely used in patients with cardiovascular diseases. However, for optimal OAC self-care patients must have skills, among which health literacy (HL) is highlighted. We aimed to describe the relation between HL and self-care in cardiovascular patients on OAC treatment. METHODS: Electronic searches were carried out in the PubMed, Scopus, Embase, CINAHL, Web of Science, Cochrane Library, SciELO, IME-Biomedicina, CUIDEN Plus and LILACS databases, limited to Spanish and English language and between January 2000-December 2016. Papers reported on adults older than 18 years, taking OAC by themselves for at least three months. PRISMA guidelines were used for paper selection. RESULTS: We identified 142 articles and finally included 10; almost all of them about warfarin. Our results suggest that in patients taking OAC treatments there is a positive relationship between HL and the level of knowledge. In addition, a small percentage of participants on the selected papers recognized the side effects and complications associated with OAC treatment. Lower HL level was associated with greater knowledge deficits and less adherence to treatment. CONCLUSION: There is a paucity of research evaluating the effect of HL on diverse aspects of OAC treatments. There is a need to expand the evidence base regarding appropriate HL screening tools, determinants of adequate knowledge and optimal behaviours related to OAC self-management. PMID- 30286745 TI - Successfully treating 90 patients with obsessive compulsive disorder in eight days: the Bergen 4-day treatment. AB - BACKGROUND: Oslo University Hospital, Norway, had by autumn 2016, accumulated a waiting list of 101 patients with obsessive-compulsive disorder (OCD) who had a legal right to receive treatment by a specialized OCD team. In this challenging situation, the Bergen OCD-team suggested to solve the problem by offering all patients an option for the rapid Bergen 4-day treatment (B4DT). The B4DT is an individual treatment delivered during four consecutive days in a group of six patients with the same number of therapists. The approach has previously shown a post-treatment response rate of 90% and a 3-month remission rate of 70%. METHODS: Ninety-seven of the wait-list patients were available for the scheduled time slots, and 90 received the 4-day format during 8 days (45 patients each week). The therapists were recruited from 22 different specialized OCD-teams from all over Norway, and 44 (68%) had not previously delivered the 4-day format. RESULTS: Post-treatment; 91.1% of the patients were classified as responders, and 72.2% were in remission. At 3-month follow-up; 84.4 were classified as responders and the remission rate was 67.7%. Oslo University Hospital now offers the 4-day treatment as standard treatment for OCD. CONCLUSIONS: We conclude that the B4DT is an acceptable and potentially effective OCD-treatment. PMID- 30286747 TI - The hsa-miR-181a-5p reduces oxidation resistance by controlling SECISBP2 in osteoarthritis. AB - BACKGROUND: The phenotypes of osteoarthritis (OA) consist of cartilage extracellular matrix (ECM) metabolism disorder and the breakdown of cartilage homeostasis, which are induced by pro-inflammatory factors and oxidative stress. Selenoproteins regulated by selenocysteine insertion sequence binding protein 2 (SBP2) are highly effective antioxidants, but their regulatory mechanisms, particularly the involvement of miRNAs, are not fully understood. METHODS: To explore whether miR-181a-5p and SBP2 are involved in OA pathogenesis, we established an IL-1beta model using the chondrocyte SW1353 cell line. Next, we up or down-regulated SBP2 and miRNA-181a-5p expression in the cells. Finally, we measured the expression of miRNA-181a-5p, SBP2 and three selenoproteins in OA cartilage and peripheral blood. RESULTS: The results showed that IL-1beta increased hsa-miR-181a-5p and decreased SBP2 in a time- and dose-dependent manner. GPX1 and GPX4, which encode crucial glutathione peroxidase antioxidant enzymes, were up-regulated along with SBP2 and miR-181a-5p. Furthermore, SBP2 showed a significant negative correlation with miR-181a-5p during induced ATDC5 cell differentiation. There was lower GPX1 and GPX4 mRNA expression and SBP2 protein expression in damaged cartilage than in smooth cartilage from the same OA sample, and hsa-miR-181a-5p expression on the contrary. Similar results were observed in peripheral blood. In conclusion, we have reported a novel pathway in which pro-inflammatory factors, miRNA, SBP2 and selenoproteins are associated with oxidation resistance in cartilage. CONCLUSION: Overall, this study provides the first comprehensive evidence that pro-inflammatory factors cause changes in the cartilage antioxidant network and describes the discovery of novel mediators of cartilage oxidative stress and OA pathophysiology. Our data suggest that miR 181a-5p may be used to develop novel early-stage diagnostic and therapeutic strategies for OA. PMID- 30286746 TI - "How am I going to live?": exploring barriers to ART adherence among adolescents and young adults living with HIV in Uganda. AB - BACKGROUND: Studies from sub-Saharan Africa (SSA) document how barriers to ART adherence present additional complications among adolescents and young adults living with HIV. We qualitatively explored barriers to ART adherence in Uganda among individuals age 14-24 to understand the unique challenges faced by this age group. METHODS: We conducted focus group (FG) discussions with Community Advisory Board members (n = 1), health care providers (n = 2), and male and female groups of adolescents age 14-17 (n = 2) and youth age 18-24 (n = 2) in Kampala, Uganda. FGs were transcribed verbatim and translated from Luganda into English. Two investigators independently reviewed all transcripts, developed a detailed codebook, achieved a pooled Cohen's Kappa of 0.79 and 0.80, and used a directed content analysis to identify key themes. RESULTS: Four barriers to ART adherence emerged: 1) poverty limited adolescents' ability to buy food and undercut efforts to become economically independent in their transition from adolescence to adulthood; 2) school attendance limited their privacy, further disrupting ART adherence; 3) family support was unreliable, and youth often struggled with a constant change in guardianship because they had lost their biological parents to HIV. In contrast peer influence, especially among HIV-positive youth, was strong and created an important network to support ART adherence; 4) the burden of taking multiple medications daily frustrated youth, often leading to so-called 'drug holidays.' Adolescent and youth-specific issues around disclosure emerged across three of the four barriers. CONCLUSIONS: To be effective, programs and policies to improve ART adherence among youth in Uganda must address the special challenges that adolescents and young adults confront in achieving optimal adherence. For example, training on budgeting and savings practices could help promote their transition to financial independence. School staff could develop strategies to help students take their medications consistently and confidentially. While challenging to extend the range of services provided by HIV clinics, successful efforts will require engaging the family, peers, and larger community of health and educational providers to support adolescents and young adults living with HIV to live longer and healthier lives.

PMID- 30286748 TI - Balancing feasibility and comprehensiveness: examining medications for reducing emergency hospital admissions. AB - Emergency hospital admissions are common, with several interventions having been developed to reduce their rates. Bobrovitz et al. summarized the available body of evidence regarding pharmacologic therapies aimed at reducing emergency hospital admissions, and identified 28 medications for which high- or moderate quality evidence supports their use, 11 of which were identified as being supported by current guideline recommendations. Additionally, the authors identified 28 medications supported by low- or very low-quality evidence, which can serve as targets for future research. The article by Bobrovitz et al. presents a good summary of the evidence, albeit with limitations in the search strategy that cannot guarantee the review as comprehensive. Despite this, the review has important implications for policymakers, guideline panels, researchers, clinicians, and funders since the identified medications can either be targets for quality improvement initiatives or for future research. Bobrovitz et al.'s review highlights the challenge that systematic reviewers face when balancing feasibility and comprehensiveness.Please see related article: https://bmcmedicine.biomedcentral.com/articles/10.1186/s12916-018-1104-9. PMID- 30286749 TI - Two decades of antenatal and delivery care in Uganda: a cross-sectional study using Demographic and Health Surveys. AB - BACKGROUND: Uganda halved its maternal mortality to 343/100,000 live births between 1990 and 2015, but did not meet the Millennium Development Goal 5. Skilled, timely and good quality antenatal (ANC) and delivery care can prevent the majority of maternal/newborn deaths and stillbirths. We examine coverage, equity, sector of provision and content of ANC and delivery care between 1991 and 2011. METHODS: We conducted a repeated cross-sectional study using four Uganda Demographic and Health Surveys (1995, 2000, 2006 and 2011).Using the most recent live birth and adjusting for survey sampling, we estimated percentage and absolute number of births with ANC (any and 4+ visits), facility delivery, caesarean sections and complete maternal care. We assessed socio-economic differentials in these indicators by wealth, education, urban/rural residence, and geographic zone on the 1995 and 2011 surveys. We estimated the proportions of ANC and delivery care provided by the public and private (for-profit and not-for profit) sectors, and compared content of ANC and delivery care between sectors. Statistical significance of differences were evaluated using chi-square tests. RESULTS: Coverage with any ANC remained high over the study period (> 90% since 2001) but was of insufficient frequency; < 50% of women who received any ANC reported 4+ visits. Facility-based delivery care increased slowly, reaching 58% in 2011. While significant inequalities in coverage by wealth, education, residence and geographic zone remained, coverage improved for all indicators among the lowest socio-economic groups of women over time. The private sector market share declined over time to 14% of ANC and 25% of delivery care in 2011. Only 10% of women with 4+ ANC visits and 13% of women delivering in facilities received all measured care components. CONCLUSIONS: The Ugandan health system had to cope with more than 30,000 additional births annually between 1991 and 2011. The majority of women in Uganda accessed ANC, but this contact did not result in care of sufficient frequency, content, and continuum of care (facility delivery). Providers in both sectors require quality improvements. Achieving universal health coverage and maternal/newborn SDGs in Uganda requires prioritising poor, less educated and rural women despite competing priorities for financial and human resources. PMID- 30286750 TI - A simulation tool for better management of retinal services. AB - BACKGROUND: Advances in the management of retinal diseases have been fast-paced as new treatments become available, resulting in increasing numbers of patients receiving treatment in hospital retinal services. These patients require frequent and long-term follow-up and repeated treatments, resulting in increased pressure on clinical workloads. Due to limited clinic capacity, many National Health Service (NHS) clinics are failing to maintain recommended follow-up intervals for patients receiving care. As such, clear and robust, long term retinal service models are required to assess and respond to the needs of local populations, both currently and in the future. METHODS: A discrete event simulation (DES) tool was developed to facilitate the improvement of retinal services by identifying efficiencies and cost savings within the pathway of care. For a mid-size hospital in England serving a population of over 500,000, we used 36 months of patient level data in conjunction with statistical forecasting and simulation to predict the impact of making changes within the service. RESULTS: A simulation of increased demand and a potential solution of the 'Treat and Extend' (T&E) regimen which is reported to result in better outcomes, in combination with virtual clinics which improve quality, effectiveness and productivity and thus increase capacity is presented. Without the virtual clinic, where T&E is implemented along with the current service, we notice a sharp increase in the number of follow-ups, number of Anti-VEGF injections, and utilisation of resources. In the case of combining T&E with virtual clinics, there is a negligible (almost 0%) impact on utilisation of resources. CONCLUSIONS: Expansion of services to accommodate increasing number of patients seen and treated in retinal services is feasible with service re-organisation. It is inevitable that some form of initial investment is required to implement service expansion through T&E and virtual clinics. However, modelling with DES indicates that such investment is outweighed by cost reductions in the long term as more patients receive optimal treatment and retain vision with better outcomes. The model also shows that the service will experience an average of 10% increase in surplus capacity. PMID- 30286751 TI - Contracting-out urban primary health care in Bangladesh: a qualitative exploration of implementation processes and experience. AB - BACKGROUND: Contracting-out (CO) to non-state providers is used widely to increase access to health care, but it entails many implementation challenges. Using Bangladesh's two decades of experience with contracting out Urban Primary Health Care (UPHC), this paper identifies contextual, contractual, and actor related factors that require consideration when implementing CO in Low- and Middle- Income Countries. METHODS: This qualitative case-study is based on 42 in depth interviews with past and present stakeholders working with the government and the UPHC project, as well as a desk review of key project documents. The Health Policy Triangle framework is utilized to differentiate among multiple intersecting contextual, contractual and actor-related factors that characterize and influence complex implementation processes. RESULTS: In Bangladesh, the contextual factors, both intrinsic and extrinsic to the health system, deeply impacted the CO process. These included competition with other health projects, public sector reforms, and the broader national level political and bureaucratic environment. Providing free services to the poor and a target to recover cost were two contradictory conditions set out in the contract and were difficult for providers to achieve. In relation to actors, the choice of the executing body led to complications, functionally disempowering local government institutions (cities and municipalities) from managing CO processes, and discouraging integration of CO arrangements into the broader national health system. Politics and power dynamics undermined the ethical selection of project areas. Ultimately, these and other factors weakened the project's ability to achieve one of its original objectives: to decentralize management responsibilities and develop municipal capacity in managing contracts. CONCLUSIONS: This study calls attention to factors that need to be addressed to successfully implement CO projects, both in Bangladesh and similar countries. Country ownership is crucial for adapting and integrating CO in national health systems. Concurrent processes must be ensured to develop local CO capacity. CO modalities must be adaptable and responsive to changing context, while operating within an agreed-upon and appropriate legal framework with a strong ethical foundation. PMID- 30286752 TI - On the epidemiology of Plasmodium vivax malaria: past and present with special reference to the former USSR. AB - Presently, many malaria-endemic countries in the world are transitioning towards malaria elimination. Out of the 105 countries with ongoing malaria transmission, 10 countries are classified as being in the pre-elimination phase of malaria control, and 9 countries are in the malaria elimination stage, whereas 7 countries are classified as being in the prevention of introduction phase. Between 2000 and 2015, 17 countries eliminated malaria (i.e., attained zero indigenous cases for 3 years or more). Seven countries were certified by the WHO as having successfully eliminated malaria. The purpose of this review was to analyse the epidemiological characteristics of vivax malaria during the various stages of malaria eradication (elimination) programmes in different countries in the past and present. Experiences of the republics of the former USSR with malaria are interesting, particularly since the data overwhelmingly were published in Russian and might not be known to western readers. Among the most important characteristics of Plasmodium vivax epidemiology at present are changes in the ratio of the short-incubation P. vivax to long-incubation P. vivax, the incidence of severe P. vivax cases, the increased numbers of asymptomatic P. vivax cases, the reduced response to anti-malarials and a few others. Various factors contributing towards the peculiarities of P. vivax epidemiology are discussed. PMID- 30286753 TI - The head shaft angle is associated with hip displacement in children at GMFCS levels III-V - a population based study. AB - BACKGROUND: An increased Head Shaft Angle (HSA) has been reported as a risk factor for hip displacement in children with cerebral palsy (CP) but opinions differ in the literature. The purpose of this study was to re-evaluate the relationship between HSA and hip displacement in a different population of children with CP. METHODS: The Cerebral Palsy Integrated Pathway Scotland surveillance programme includes 95% of all children with CP in Scotland. The pelvic radiographs from 640 children in GMFCS levels III-V were chosen. The most displaced hip was analysed and the radiographs used were those taken at the child's first registration in the database to avoid the potential effects of surveillance on subsequent hip centration. A logistic regression model was used with hip displacement (migration percentage [MP] >=40%) as outcome and HSA, GMFCS, age and sex as covariates. RESULTS: The MP was >=40% in 118 hips with a mean HSA of 164 degrees (range 121-180 degrees ) and < 40% in 522 hips with a mean HSA of 160 degrees (range 111-180 degrees ). The logistic regression analysis showed no significant influence of age and sex on MP in this population but a high GMFCS level was strongly associated with hip displacement. An increased HSA was also associated with hip displacement, a 10 degrees difference in HSA for children adjusted for age, sex, and GMFCS gave an odds ratio of 1.26 for hip displacement equal or above 40% (p = 0.009) and hips with HSA above 164.5 degrees had an odds ratio of 1.96 compared with hips with HSA below 164.5 degrees (p = 0.002). CONCLUSION: These findings confirm that HSA is associated with hip displacement in children in GMFCS levels III-V. PMID- 30286754 TI - Computational analysis of the interactions of a novel cephalosporin derivative with beta-lactamases. AB - BACKGROUND: One of the main concerns of the modern medicine is the frightening spread of antimicrobial resistance caused mainly by the misuse of antibiotics. The researchers worldwide are actively involved in the search for new classes of antibiotics, and for the modification of known molecules in order to face this threatening problem. We have applied a computational approach to predict the interactions between a new cephalosporin derivative containing an additional beta lactam ring with different substituents, and several serine beta-lactamases representative of the different classes of this family of enzymes. RESULTS: The results of the simulations, performed by using a covalent docking approach, has shown that this compound, although able to bind the selected beta-lactamases, has a different predicted binding score for the two beta-lactam rings, suggesting that one of them could be more resistant to the attack of these enzymes and stay available to perform its bactericidal activity. CONCLUSIONS: The detailed analysis of the complexes obtained by these simulations suggests possible hints to modulate the affinity of this compound towards these enzymes, in order to develop new derivatives with improved features to escape to degradation.

AB - BACKGROUND: Although reducing sugar-sweetened beverage (SSB) intake is an important behavioral strategy to improve health, no known SSB-focused behavioral trial has examined maintenance of SSB behaviors after an initial reduction. Guided by the RE-AIM framework, this study examines 6-18 month and 0-18 month individual-level maintenance outcomes from an SSB reduction trial conducted in a medically-underserved, rural Appalachia region of Virginia. Reach and implementation indicators are also reported. METHODS: Following completion of a 6 month, multi-component, behavioral RCT to reduce SSB intake (SIPsmartER condition vs. comparison condition), participants were further randomized to one of three 12-month maintenance conditions. Each condition included monthly telephone calls, but varied in mode and content: 1) interactive voice response (IVR) behavior support, 2) human-delivered behavior support, or 3) IVR control condition. Assessments included the Beverage Intake Questionnaire (BEVQ-15), weight, BMI, and quality of life. Call completion rates and costs were tracked. Analysis included descriptive statistics and multilevel mixed-effects linear regression models using intent-to-treat procedures. RESULTS: Of 301 subjects enrolled in the 6-month RCT, 242 (80%) were randomized into the maintenance phase and 235 (78%) included in the analyses. SIPsmartER participants maintained significant 0-18 month decreases in SSB. For SSB, weight, BMI and quality of life, there were no significant 6-18 month changes among SIPsmartER participants, indicating post program maintenance. The IVR-behavior participants reported greater reductions in SSB kcals/day during the 6-18 month maintenance phase, compared to the IVR control participants (- 98 SSB kcals/day, 95% CI = - 196, - 0.55, p < 0.05); yet the human-delivered behavior condition was not significantly different from either the IVR-behavior condition (27 SSB kcals/day, 95% CI = - 69, 125) or IVR control condition (- 70 SSB kcals/day, 95% CI = - 209, 64). Call completion rates were similar across maintenance conditions (4.2-4.6 out of 11 calls); however, loss to follow-up was greatest in the IVR control condition. Approximated costs of IVR and human-delivered calls were remarkably similar (i.e., $3.15/participant/month or $38/participant total for the 12-month maintenance phase), yet implications for scalability and sustainability differ. CONCLUSION: Overall, SIPsmartER participants maintained improvements in SSB behaviors. Using IVR to support SSB behaviors is effective and may offer advantages as a scalable maintenance strategy for real-world systems in rural regions to address excessive SSB consumption.

PMID- 30286757 TI - Government resource contributions to the private-not-for-profit sector in Uganda: evolution, adaptations and implications for universal health coverage. AB - BACKGROUND: A case study was prepared examining government resource contributions (GRCs) to private-not-for-profit (PNFP) providers in Uganda. It focuses on Primary Health Care (PHC) grants to the largest non-profit provider network, the Uganda Catholic Medical Bureau (UCMB), from 1997 to 2015. The framework of complex adaptive systems was used to explain changes in resource contributions and the relationship between the Government and UCMB. METHODS: Documents and key informant interviews with the important actors provided the main sources of qualitative data. Trends for GRCs and service outputs for the study period were constructed from existing databases used to monitor service inputs and outputs. The case study's findings were validated during two meetings with a broad set of stakeholders. RESULTS: Three major phases were identified in the evolution of GRCs and the relationship between the Government and UCMB: 1) Initiation, 2) Rapid increase in GRCs, and 3) Declining GRCs. The main factors affecting the relationship's evolution were: 1) Financial deficits at PNFP facilities, 2) advocacy by PNFP network leaders, 3) changes in the government financial resource envelope, 4) variations in the "good will" of government actors, and 5) changes in donor funding modalities. Responses to the above dynamics included changes in user fees, operational costs of PNFPs, and government expectations of UCMB. Quantitative findings showed a progressive increase in service outputs despite the declining value of GRCs during the study period. CONCLUSIONS: GRCs in Uganda have evolved influenced by various factors and the complex interactions between government and PNFPs. The Universal Health Coverage (UHC) agenda should pay attention to these factors and their interactions when shaping how governments work with PNFPs to advance UHC. GRCs could be leveraged to mitigate the financial burden on communities served by PNFPs. Governments seeking to advance UHC goals should explore policies to expand GRCs and other modalities to subsidize the operational costs of PNFPs.

Clinical evaluation has limited accuracy for the early identification of the patients progressing towards the fatal condition. Researchers have tried to identify the serum and the plasma based indicators of the severe malaria. Discovery of MicroRNA (miRNA) has opened up an era of identification of early biomarkers for various infectious and non infectious diseases. MicroRNAs (miRNA) are the small non-coding RNA molecules of length 19-24 nts and are responsible for the regulation of the majority of human gene expressions at post transcriptional level. METHODS: We identified the differentially expressed miRNAs by microarray and validated the selected miRNAs by qRT-PCR. We assessed the diagnostic potential of these up-regulated miRNAs for complicated P. vivax malaria. Futher, the bioinformtic analysis was performed to construct protein-protein and mRNA-miRNA networks to identify highly regulated miRNA. RESULTS: In the present study, utility of miRNA as potential biomarker of complicated P. vivax malaria was explored. A total of 276 miRNAs were found to be differentially expressed by miRNA microarray and out of which 5 miRNAs (hsa-miR 7977, hsa-miR-28-3p, hsa-miR-378-5p, hsa-miR-194-5p and hsa-miR-3667-5p) were found to be significantly up-regulated in complicated P. vivax malaria patients using qRT-PCR. The diagnostic potential of these 5 miRNAs were found to be significant with sensitivity and specificity of 60-71% and 69-81% respectively and area under curve (AUC) of 0.7 (p < 0.05). Moreover, in silico analysis of the common targets of up-regulated miRNAs revealed UBA52 and hsa-miR-7977 as majorly regulated hubs in the PPI and mRNA-miRNA networks, suggesting their putative role in complicated P. vivax malaria. CONCLUSION: miR-7977 might act as a potential biomarker for differentiating complicated P. vivax malaria from uncomplicated type. The elevated levels of miR-7977 may have a role to play in the disease pathology through UBA52 or TGF-beta signalling pathway. PMID- 30286758 TI - Towards universal health coverage: a mixed-method study mapping the development of the faith-based non-profit sector in the Ghanaian health system. AB - BACKGROUND: Faith-based non-profit (FBNP) providers have had a long-standing role as non-state, non-profit providers in the Ghanaian health system. They have historically been considered to be important in addressing the inequitable geographical distribution of health services and towards the achievement of universal health coverage (UHC), but in changing contexts, this contribution is being questioned. However, any assessment of contribution is hampered by the lack of basic information about their comparative presence and coverage in the Ghanaian health system. In response, since the 1950s, there have been repeated calls for the 'mapping' of faith-based health assets. METHODS: A historically focused mixed-methods study was conducted, collecting qualitative and quantitative data and combining geospatial mapping with varied documentary resources (secondary and primary, current and archival). Geospatial maps were developed, providing a visual representation of changes in the spatial footprint of the Ghanaian FBNP health sector. RESULTS: The geospatial maps show that FBNPs were originally located in rural remote areas of the country but that this service footprint has evolved over time, in line with changing social, political and economic contexts. CONCLUSION: FBNPs have had a long-standing role in the provision of health services and remain a valuable asset within national health systems in Ghana and sub-Saharan Africa more broadly. Collaboration between the public sector and such non-state providers, drawing on the comparative strengths and resources of FBNPs and focusing on whole system strengthening, is essential for the achievement of UHC. PMID- 30286759 TI - Molecular network-based identification of competing endogenous RNAs and mRNA signatures that predict survival in prostate cancer. AB - BACKGROUND: The aim of the study is described the regulatory mechanisms and prognostic values of differentially expressed RNAs in prostate cancer and construct an mRNA signature that predicts survival. METHODS: The RNA profiles of 499 prostate cancer tissues and 52 non-prostate cancer tissues from TCGA were analyzed. The differential expression of RNAs was examined using the edgeR package. Survival was analyzed by Kaplan-Meier method. microRNA (miRNA), messenger RNA (mRNA), and long non-coding RNA (lncRNA) networks from the miRcode database were constructed, based on the differentially expressed RNAs between non prostate and prostate cancer tissues. RESULTS: A total of 773 lncRNAs, 1417 mRNAs, and 58 miRNAs were differentially expressed between non-prostate and prostate cancer samples. The newly constructed ceRNA network comprised 63 prostate cancer-specific lncRNAs, 13 miRNAs, and 18 mRNAs. Three of 63 differentially expressed lncRNAs and 1 of 18 differentially expressed mRNAs were significantly associated with overall survival in prostate cancer (P value < 0.05). After the univariate and multivariate Cox regression analyses, 4 mRNAs (HOXB5, GPC2, PGA5, and AMBN) were screened and used to establish a predictive model for the overall survival of patients. Our ROC curve analysis revealed that the 4-mRNA signature performed well. CONCLUSION: These ceRNAs may play a critical role in the progression and metastasis of prostate cancer and are thus candidate therapeutic targets and potential prognostic biomarkers. A novel model that incorporated these candidates was established and might provide more powerful prognostic information in predicting survival in prostate cancer. PMID- 30286761 TI - Perceptions of patients with chronic obstructive pulmonary disease and their health care providers towards using mHealth for self-management of exacerbations: a qualitative study. AB - BACKGROUND: Self-management of exacerbations in COPD patients is important to reduce exacerbation impact. There is a need for more comprehensive and individualized interventions to improve exacerbation-related self-management behavior. The use of mobile health (mHealth) could help to achieve a wide variety of behavioral goals. Understanding of patients and health care providers perspectives towards using mHealth in promoting self-management will greatly enhance the development of solutions with optimal usability and feasibility. Therefore, the aim of this study was to explore perceptions of COPD patients and their health care providers towards using mHealth for self-management of exacerbations. METHODS: A qualitative study using focus group interviews with COPD patients (n = 13) and health care providers (HCPs) (n = 6) was performed to explore perceptions towards using mHealth to support exacerbation-related self management. Data were analyzed by a thematic analysis. RESULTS: COPD patients and HCPs perceived mostly similar benefits and barriers of using mHealth for exacerbation-related self-management. These perceived benefits and barriers seem to be important drivers in the willingness to use mHealth. Both patients and HCPs strengthen the need for a multi-component and tailored mHealth intervention that improves patients' exacerbation-related self-management by determining their health status and providing adequate information, decision support and feedback on self-management behavior. Most importantly, patients and HCPs considered an mHealth intervention as support to improve self-management and emphasized that it should never replace patients' own feelings nor undermine their own decisions. In addition, the intervention should be complementary to regular contact with HCPs, as personal contact with a HCP was considered to be very important. To optimize engagement with mHealth, patients should have a positive attitude toward using mHealth and an mHealth intervention should be attractive, rewarding and safe. CONCLUSIONS: This study provided insight into perceptions of COPD patients and their HCPs towards using mHealth for self-management of exacerbations. This study points out that future mHealth interventions should focus on developing self management skills over time by providing adequate information, decision support and feedback on self-management behavior and that mHealth should complement regular care. To optimize engagement, mHealth interventions should be attractive, rewarding, safe and tailored to the patient needs. PMID- 30286760 TI - Effects of a single dose of beetroot juice on cycling time trial performance at ventilatory thresholds intensity in male triathletes. AB - BACKGROUND: Beetroot juice (BJ) is classified as a high-level supplement for improving sports performance. There is some controversy over the benefits of BJ supplementation for endurance exercise performance, especially when referring to well-trained athletes. This study examines the effects of acute BJ supplementation on cardioventilatory responses, exercise economy/efficiency, slow component of oxygen uptake, time trial performance, blood lactate, energy consumption, and carbohydrate and fat oxidation. METHODS: Twelve well-trained, male triathletes (aged 21-47 yr) were assigned in a randomized, double-blind, crossover design to receive 70 ml of BJ (6.5 mmol NO3-) or placebo (PL). Three hours after taking the supplement, participants completed an endurance test on a cycle ergometer at a constant work rate (W) corresponding to first ventilatory threshold (VT1) (30 min) and second ventilatory threshold (VT2) time trial (~ 15 min). RESULTS: Maximal oxygen uptake was 54.78 +/- 3.13 mL.min- 1.kg- 1, and gross efficiency was > 22% at each load intensity and experimental condition. No significant interaction effect (supplement*intensity) was observed on any of the cardioventilatory variables, efficiency/economy, VT2 time trial, energy expenditure, carbohydrate oxidation and fat oxidation (p > 0.05). CONCLUSION: Our findings do not support an improvement in the variables examined in response to acute BJ supplementation. Probably, higher doses are needed for improving time trial performance in male triathletes during a cycle ergometer test conducted at a load intensity equivalent to the first and second ventilatory threshold. PMID- 30286762 TI - Prognostic significance of metastatic lymph node ratio: the lymph node ratio could be a prognostic indicator for patients with gastric cancer. AB - BACKGROUND: To demonstrate the prognostic significance and value of lymph node ratio (LNR) and evaluate the possibility of becoming a new indicator to enhance the current Union for International Cancer Control (UICC)/American Joint Committee on Cancer (AJCC) tumor, lymph node, metastasis (TNM) staging system. METHODS: Our retrospective study included 221 patients who got gastric cancer and underwent curative gastrectomy between 2005 and 2012 at the Fourth Hospital Affiliated of China Medical University. The log-rank test was used to compare the clinicopathological variables. The Kaplan-Meier method and Cox proportional hazard regression model was used to perform the univariate analysis and multivariate statistical survival analysis. RESULTS: The patients with a better differentiated pathological type; an earlier stage of T staging, N staging, and TNM staging; and a lesser LNR would have a longer survival time according to the univariate analysis. As for the multivariate analysis, the Grade, T stage, N stage, and LNR had the statistical significance. Both in group 1 (the number of lymph nodes examined >= 15, namely LN >= 15) and group 2 (LN < 15), the LNR had statistical significance and the median survival time would decrease with the increase of the LNR. It was still statistically significant between group LNR1 and group LNR2 which were regrouped by the new cut-off value. CONCLUSION: The LNR could estimate the prognosis of patients with curative gastrectomy regardless of the number of lymph nodes examined. Thus LNR could become a new indicator to enhance the current TNM stage system. PMID- 30286763 TI - Realities and experiences of community health volunteers as agents for behaviour change: evidence from an informal urban settlement in Kisumu, Kenya. AB - BACKGROUND: Community health workers play an important role in health service delivery and are increasingly involved in behaviour change interventions, including for hygiene-related behaviour change. However, their role and capacity to deliver behaviour change interventions, particularly in high-density urban settlements, remain under-researched. This study examines the behaviour change related activities of community health volunteers (CHVs)-community health workers affiliated with the Kenyan Ministry of Health-in a peri-urban settlement in Kenya, in order to assess their capabilities, opportunities to work effectively, and sources of motivation. METHODS: This mixed-methods study included a census of 16 CHVs who work in the study area. All CHVs participated in structured observations of their daily duties, structured questionnaires, in-depth interviews, and two focus group discussions. Structured data were analysed descriptively. Thematic content analysis was followed for qualitative data. Results were synthesized and interpreted using the capability, opportunity, motivation for behaviour change framework, COM-B. RESULTS: In addition to their responsibilities with the Ministry of Health, CHVs partnered with a range of non governmental organizations engaged in health and development programming, often receiving small stipends from these organizations. CHVs reported employing a limited number of behaviour change techniques when interacting with community members at the household level. Capability: While supervision and support from the MOH was robust, CHV training was inconsistent and inadequate with regard to behaviour change and CHVs often lacked material resources necessary for their work. Opportunity: CHVs spent very little time with the households in their allocated catchment area. The number of households contacted per day was insufficient to reach all assigned households within a given month as required and the brief time spent with households limited the quality of engagement. MOTIVATION: Lack of compensation was noted as a demotivating factor for CHVs. This was compounded by the challenging social environment and CHVs' low motivation to encourage behaviour change in local communities. CONCLUSIONS: In a complex urban environment, CHVs faced challenges that limited their capacity to be involved in behaviour change interventions. More resources, better coordination, and additional training in modern behaviour change approaches are needed to ensure their optimal performance in implementing health programmes.

PMID- 30286764 TI - RNA-induced epigenetic silencing inhibits HIV-1 reactivation from latency. AB - BACKGROUND: Current antiretroviral therapy is effective in controlling HIV-1 infection. However, cessation of therapy is associated with rapid return of viremia from the viral reservoir. Eradicating the HIV-1 reservoir has proven difficult with the limited success of latency reactivation strategies and reflects the complexity of HIV-1 latency. Consequently, there is a growing need for alternate strategies. Here we explore a "block and lock" approach for enforcing latency to render the provirus unable to restart transcription despite exposure to reactivation stimuli. Reactivation of transcription from latent HIV-1 proviruses can be epigenetically blocked using promoter-targeted shRNAs to prevent productive infection. We aimed to determine if independent and combined expression of shRNAs, PromA and 143, induce a repressive epigenetic profile that is sufficiently stable to protect latently infected cells from HIV-1 reactivation when treated with a range of latency reversing agents (LRAs). RESULTS: J-Lat 9.2 cells, a model of HIV-1 latency, expressing shRNAs PromA, 143, PromA/143 or controls were treated with LRAs to evaluate protection from HIV-1 reactivation as determined by levels of GFP expression. Cells expressing shRNA PromA, 143, or both, showed robust resistance to viral reactivation by: TNF, SAHA, SAHA/TNF, Bryostatin/TNF, DZNep, and Chaetocin. Given the physiological importance of TNF, HIV-1 reactivation was induced by TNF (5 ng/mL) and ChIP assays were performed to detect changes in expression of epigenetic markers within chromatin in both sorted GFP- and GFP+ cell populations, harboring latent or reactivated proviruses, respectively. Ordinary two-way ANOVA analysis used to identify interactions between shRNAs and chromatin marks associated with repressive or active chromatin in the integrated provirus revealed significant changes in the levels of H3K27me3, AGO1 and HDAC1 in the LTR, which correlated with the extent of reduced proviral reactivation. The cell line co-expressing shPromA and sh143 consistently showed the least reactivation and greatest enrichment of chromatin compaction indicators. CONCLUSION: The active maintenance of epigenetic silencing by shRNAs acting on the HIV-1 LTR impedes HIV-1 reactivation from latency. Our "block and lock" approach constitutes a novel way of enforcing HIV-1 "super latency" through a closed chromatin architecture that renders the virus resistant to a range of latency reversing agents. PMID- 30286767 TI - Contracting-out primary health care services in Tanzania towards UHC: how policy processes and context influence policy design and implementation. AB - BACKGROUND: Governments increasingly recognize the need to engage non-state providers (NSPs) in health systems in order to move successfully towards Universal Health Coverage (UHC). One common approach to engaging NSPs is to contract-out the delivery of primary health care services. Research on contracting arrangements has typically focused on their impact on health service delivery; less is known about the actual processes underlying the development and implementation of interventions and the contextual factors that influence these. This paper reports on the design and implementation of service agreements (SAs) between local governments and NSPs for the provision of primary health care services in Tanzania. It examines the actors, policy process, context and policy content that influenced how the SAs were designed and implemented. METHODS: We used qualitative analytical methods to study the Tanzanian experience with contracting- out. Data were drawn from document reviews and in-depth interviews with 39 key informants, including six interviews at the national and regional levels and 33 interviews at the district level. All interviews were audiotaped, transcribed and translated into English. Data were managed in NVivo (version 10.0) and analyzed thematically. RESULTS: The institutional frameworks shaping the engagement of the government with NSPs are rooted in Tanzania's long history of public-private partnerships in the health sector. Demand for contractual arrangements emerged from both the government and the faith-based organizations that manage NSP facilities. Development partners provided significant technical and financial support, signaling their approval of the approach. Although districts gained the mandate and power to make contractual agreements with NSPs, financing the contracts remained largely dependent on donor funds via central government budget support. Delays in reimbursements, limited financial and technical capacity of local government authorities and lack of trust between the government and private partners affected the implementation of the contractual arrangements. CONCLUSIONS: Tanzania's central government needs to further develop the technical and financial capacity necessary to better support districts in establishing and financing contractual agreements with NSPs for primary health care services. Furthermore, forums for continuous dialogue between the government and contracted NSPs should be fostered in order to clarify the expectations of all parties and resolve any misunderstandings. PMID- 30286765 TI - Rhomboid domain-containing protein 1 promotes breast cancer progression by regulating the p-Akt and CDK2 levels. AB - BACKGROUND: Our previous work revealed that rhomboid domain-containing protein 1 (RHBDD1) participates in the modulation of cell growth and apoptosis in colorectal cancer cells. This study aimed to investigate the function of RHBDD1 in regulating breast cancer progression and its underlying molecular basis. METHODS: Immunohistochemistry was performed to evaluate RHBDD1 expression in 116 breast cancer tissue and 39 adjacent normal tissue and expression of RHBDD1, phospho-Akt (p-Akt) and cyclin-dependent kinase 2 (CDK2) in the same 84 breast cancer specimens. RHBDD1-knock-out cells were established using breast cancer cell lines. In vitro studies were carried out to estimate the function of RHBDD1 in cell proliferation, migration and invasion. Fluorescence microscopy assay and flow cytometric analysis were used to measure apoptosis and cell cycle regulation. RNA sequencing and western blot analysis were used to investigate the molecular mechanisms of RHBDD1. RESULTS: RHBDD1 was highly up-regulated in breast cancer tissue compared with that in normal tissue and associated with pathological tumor (pT) stage, pathological tumor-node-metastasis (pTNM) stage and estrogen receptor (ER) expression. RHBDD1 up-regulation was associated with poor prognosis in several subtypes of breast cancer. Deletion of RHBDD1 promoted apoptosis and suppressed proliferation, migration and invasion in breast cancer cells. RHBDD1 deletion suppressed Akt activation and decreased CDK2 protein level via proteasome pathway, thus inhibited cell cycle progression and G1/S phase transition. Moreover, the protein level of RHBDD1, p-Akt and CDK2 was significantly positively correlated in breast cancer tissue. CONCLUSIONS: Our study reveals that RHBDD1 promotes breast cancer progression by regulating p-Akt and CDK2 protein levels, and might be a potential biomarker and prognostic indicator for breast cancer patients. PMID- 30286768 TI - The effects of vitamin D supplementation on metabolic profiles and gene expression of insulin and lipid metabolism in infertile polycystic ovary syndrome candidates for in vitro fertilization. AB - BACKGROUND: Vitamin D deficiency in women diagnosed with polycystic ovary syndrome (PCOS) remarkably decreases the chance of pregnancy, which might be related to its impact on metabolic abnormalities in these patients. It is hypothesized that vitamin D supplementation influences metabolic profile of these patients and indirectly might affect fertility and the outcomes. Therefore, this study was conducted to determine the effects of vitamin D supplementation on the levels of anti-Mullerian hormone (AMH), metabolic profiles, and gene expression of insulin and lipid metabolism in infertile women with PCOS who were candidate for in vitro fertilization (IVF). METHODS: This study was a randomized, double blinded, placebo-controlled trial conducted among 40 infertile women, aged 18-40 years, diagnosed with PCOS and was candidate for IVF. Participants were randomly assigned into two intervention groups for receiving either 50,000 IU vitamin D or placebo (n = 20 each group) every other week for 8 weeks. Gene expression for insulin and lipid metabolism was conducted using peripheral blood mononuclear cells (PBMCs) of women with PCOS, via RT-PCR method. RESULTS: Vitamin D supplementation led to a significant reduction in serum AMH (- 0.7 +/- 1.2 vs. - 0.1 +/- 0.5 ng/mL, P = 0.02), insulin levels (- 1.4 +/- 1.6 vs. -0.3 +/- 0.9 MUIU/mL, P = 0.007), homeostatic model of assessment for insulin resistance (- 0.3 +/- 0.3 vs. -0.1 +/- 0.2, P = 0.008), and a significant increase in quantitative insulin sensitivity check index (+ 0.009 +/- 0.01 vs. + 0.001 +/- 0.004, P = 0.04), compared with the placebo. Moreover, following vitamin D supplementation there was a significant decrease in serum total- (- 5.1 +/- 12.6 vs. + 2.9 +/- 10.9 mg/dL, P = 0.03) and LDL-cholesterol levels (- 4.5 +/- 10.3 vs. + 2.5 +/- 10.6 mg/dL, P = 0.04) compared with the placebo. CONCLUSION: Overall, the findings of this trial supported that 50,000 IU vitamin D supplementation every other week for 8 weeks had beneficial effects on insulin metabolism, and lipid profile of infertile women with PCOS who are candidate for IVF. These benefits might not be evident upon having sufficient vitamin D levels.

PMID- 30286769 TI - The systemic immune-inflammation index is an independent predictor of survival for metastatic colorectal cancer and its association with the lymphocytic response to the tumor. AB - BACKGROUND: Systemic inflammation and immune dysfunction has been proved to be significantly associated with cancer progression and metastasis in many cancer types, including colorectal cancer. We examined the prognostic significance of the systemic immune-inflammation index (SII) in patients with metastatic colorectal cancer (mCRC) and the relationship between the lymphocytic response to the tumor and this index. METHODS: This retrospective study evaluated 240 consecutive patients with newly diagnosed stage IV mCRC who underwent surgical resection. The SII values were calculated based on preoperative laboratory data regarding platelet, neutrophil, and lymphocyte counts. Tumor-infiltrating lymphocytes were evaluated using the surgical specimens. The overall survival and their 95% confidence interval (95% CI) were estimated by regression analyses and the Kaplan-Meier method. RESULTS: After a mean follow-up of 26.7 (1.1-92.4) months, 146 patients (60.8%) died. In the univariate analysis, a high SII was significantly associated with poor overall survival (P = 0.009). The multivariable analysis also confirmed that a high SII was independently associated with poor overall survival (hazard ratio: 1.462, 95% confidence interval 1.049-2.038, P = 0.025). The SII value was significantly correlated with the TILs value at the tumor's center (P = 0.04), but not at the invasive margin (P = 0.39). When we evaluated overall survival for groupings of the tumor infiltrating lymphocytes and SII values, we identified three distinct prognostic groups. The group with low tumor-infiltrating lymphocyte values and high SII values had the worst prognosis. CONCLUSIONS: A high SII value independently predicts poor clinical outcomes among patients with mCRC. In addition, combining the lymphocytic response to the tumor and SII could further enhance prognostication for mCRC. PMID- 30286771 TI - Contracting non-state providers for universal health coverage: learnings from Africa, Asia, and Eastern Europe. AB - BACKGROUND: Formal engagement with non-state providers (NSP) is an important strategy in many low-and-middle-income countries for extending coverage of publicly financed health services. The series of country studies reviewed in this paper - from Afghanistan, Bangladesh, Bosnia & Herzegovina, Ghana, South Africa, Tanzania and Uganda - provide a unique opportunity to understand the dynamics of NSP engagement in different contexts. METHODS: A standard template was developed and used to summarize the main findings from the country studies. The summaries were then organized according to emergent themes and a narrative built around these themes. RESULTS: Governments contracted NSPs for a variety of reasons - limited public sector capacity, inability of public sector services to reach certain populations or geographic areas, and the widespread presence of NSPs in the health sector. Underlying these reasons was a recognition that purchasing services from NSPs was necessary to increase coverage of health services. Yet, institutional NSPs faced many service delivery challenges. Like the public sector, institutional NSPs faced challenges in recruiting and retaining health workers, and ensuring service quality. Properly managing relationships between all actors involved was critical to contracting success and the role of NSPs as strategic partners in achieving national health goals. Further, the relationship between the central and lower administrative levels in contract management, as well as government stewardship capacity for monitoring contractual performance were vital for NSP performance. CONCLUSION: For countries with a sizeable NSP sector, making full use of the available human and other resources by contracting NSPs and appropriately managing them, offers an important way for expanding coverage of publicly financed health services and moving towards universal health coverage. PMID- 30286770 TI - Factors influencing performance by contracted non-state providers implementing a basic package of health services in Afghanistan. AB - BACKGROUND: In 2002 Afghanistan's Ministry of Public Health (MoPH) and its development partners initiated a new paradigm for the health sector by electing to Contract-Out (CO) the Basic Package of Health Services (BPHS) to non-state providers (NSPs). This model is generally regarded as successful, but literature is scarce that examines the motivations underlying implementation and factors influencing program success. This paper uses relevant theories and qualitative data to describe how and why contracting out delivery of primary health care services to NSPs has been effective. The main aim of this study was to assess the contextual, institutional, and contractual factors that influenced the performance of NSPs delivering the BPHS in Afghanistan. METHODS: The qualitative study design involved individual in-depth interviews and focus group discussions conducted in six provinces of Afghanistan, as well as a desk review. The framework for assessing key factors of the contracting mechanism proposed by Liu et al. was utilized in the design, data collection and data analysis. RESULTS: While some contextual factors facilitated the CO (e.g. MoPH leadership, NSP innovation and community participation), harsh geography, political interference and insecurity in some provinces had negative effects. Contractual factors, such as effective input and output management, guided health service delivery. Institutional factors were important; management capacity of contracted NSPs affects their ability to deliver outcomes. Effective human resources and pharmaceutical management were notable elements that contributed to the successful delivery of the BPHS. The contextual, contractual and institutional factors interacted with each other. CONCLUSION: Three sets of factors influenced the implementation of the BPHS: contextual, contractual and institutional. The MoPH should consider all of these factors when contracting out the BPHS and other functions to NSPs. Other fragile states and countries emerging from a period of conflict could learn from Afghanistan's example in contracting out primary health care services, keeping in mind that generic or universal contracting policies might not work in all geographical areas within a country or between countries. PMID- 30286772 TI - Emergence of three general practitioner contracting-in models in South Africa: a qualitative multi-case study. AB - BACKGROUND: The general practitioner contracting initiative (GPCI) is a health systems strengthening initiative piloted in the first phase of national health insurance (NHI) implementation in South Africa as it progresses towards universal health coverage (UHC). GPCI aimed to address the shortage of doctors in the public sector by contracting-in private sector general practitioners (GPs) to render services in public primary health care clinics. This paper explores the early inception and emergence of the GPCI. It describes three models of contracting-in that emerged and interrogates key factors influencing their evolution. METHODS: This qualitative multi-case study draws on three cases. Data collection comprised document review, key informant interviews and focus group discussions with national, provincial and district managers as well as GPs (n = 68). Walt and Gilson's health policy analysis triangle and Liu's conceptual framework on contracting-out were used to explore the policy content, process, actors and contractual arrangements involved. RESULTS: Three models of contracting-in emerged, based on the type of purchaser: a centralized-purchaser model, a decentralized-purchaser model and a contracted-purchaser model. These models are funded from a single central source but have varying levels of involvement of national, provincial and district managers. Funds are channelled from purchaser to provider in slightly different ways. Contract formality differed slightly by model and was found to be influenced by context and type of purchaser. Conceptualization of the GPCI was primarily a nationally-driven process in a context of high-level political will to address inequity through NHI implementation. Emergence of the models was influenced by three main factors, flexibility in the piloting process, managerial capacity and financial management capacity. CONCLUSION: The GPCI models were iterations of the centralized purchaser model. Emergence of the other models was strongly influenced by purchaser capacity to manage contracts, payments and recruitment processes. Findings from the decentralized-purchaser model show importance of local context, provincial capacity and experience on influencing evolution of the models. Whilst contract characteristics need to be well defined, allowing for adaptability to the local context and capacity is critical. Purchaser capacity, existing systems and institutional knowledge and experience in contracting and financial management should be considered before adopting a decentralized implementation approach. PMID- 30286774 TI - Tibiofemoral joint contact area and stress after single-bundle anterior cruciate ligament reconstruction with transtibial versus anteromedial portal drilling techniques. AB - BACKGROUND: During single-bundle ACLR, femoral tunnel location plays an important role in restoring the intact knee mechanisms, whereas malplacement of the tunnel was cited as the most common cause of knee instability. The objective of this study is to evaluate, objectively, the tibiofemoral contact area and stress after single-bundle (SB) anterior cruciate ligament reconstruction (ACLR) with femoral tunnel positions drilled by transtibial (TT) or anteromedial (AM) portal techniques. METHODS: Seven fresh human cadaveric knees underwent ACLR by the use of TT or AM portal techniques in a randomized order. These specimens were reused for ACL-R (TT and AM). The tibiofemoral contact area and stresses were gauged by an electronic stress-sensitive film inserted into the joint space. The knee was under the femoral axial compressive load of 1000 N using a biomechanics testing machine at 0 degrees , 10 degrees , 20 degrees , and 30 degrees of flexion. Three conditions were compared: (1) intact ACL, (2) ACLR by the use of the TT method, and (3) ACLR by the use of the AM portal method. RESULTS: Compared with AM portal ACL-reconstructed knees, a significantly decreased tibiofemoral contact area on the medial compartment was detected in the TT ACL-reconstructed knees at 20 degrees of knee flexion (P = .047). Compared with the intact group, the TT ACLR group showed a higher mean stress at 20 degrees and 30 degrees of flexion on the medial compartments (P = .001, P = .003, respectively), while the AM portal ACLR group showed no significant differences at 30 degrees of flexion (P = .073). The TT ACLR group also showed a higher mean maximum stress at 20 degrees of flexion on the medial compartments (P = .047), while the AM portal ACLR group showed no significant differences at this angle(P = .319). DISCUSSION: The alternation of the tibiofemoral joint contact area and stress in reconstructed knees may be caused by the mismatch of the tibiofemoral joint during knee movement procedures compared with intact knees. CONCLUSIONS: SB ACLR by the use of the AM portal method and TT method both alter the tibiofemoral contact area and stress when compared with the intact knee. When compared with the TT technique, ACLR by the AM portal technique more closely restores the intact tibiofemoral contact area and stress at low flexion angles.

AB - BACKGROUND: Psychological symptoms are frequently present in patients scheduled for shoulder surgery. The perception of functional disability, activity level and pain in the shoulder is negatively influenced by psychological symptoms, which leads to higher scores of the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. The aim of this study was to determine the influence of psychological symptoms on the minimal clinically important difference (MCID) of the DASH score in patients after shoulder surgery. METHODS: In this prospective longitudinal cohort study, 176 patients were included. Group 1 (32 patients) had symptoms of psychological disorders before and after surgery; group 2 had no symptoms of psychological disorders (110 patients). In the remaining patients (34 patients), psychological disorders changed after surgery. Clinical outcome was measured with the change of DASH score and anchor questions for perceived improvement of pain and function after surgery. Symptoms of psychological disorders were identified with the Four-Dimensional Symptom Questionnaire. An anchor-based mean change score technique was used to determine the MCID of the DASH score. RESULTS: DASH scores before and 12 months after shoulder surgery were significantly higher in patients with symptoms of psychological disorders; change of DASH score was not different between the two groups. The MCID of the DASH score was 13.0 [SD 20.7] in the group with symptoms of psychological disorders and 12.7 [SD 17.6] in the group with no symptoms of psychological disorders. We observed no difference (p = 0.559) in the MCID between the group with and the group without symptoms of psychological disorders. CONCLUSION: Symptoms of psychological disorders had a negative effect on the DASH score but no influence on the MCID of the DASH score. The DASH score could be used in future studies to assess the influence of psychological factors on the clinical outcome of treatment. PMID- 30286776 TI - Automated functional upper limb evaluation of patients with Friedreich ataxia using serious games rehabilitation exercises. AB - BACKGROUND: Friedreich ataxia (FRDA) is a disease with neurological and systemic involvement. Clinical assessment tools commonly used for FRDA become less effective in evaluating decay in patients with advanced FRDA, particularly when they are in a wheelchair. Further motor worsening mainly impairs upper limb function. In this study, we tested if serious games (SG) developed for rehabilitation can be used as an assessment tool for upper limb function even in patients with advanced FRDA. METHODS: A specific SG has been developed for physical rehabilitation of patients suffering from neurologic diseases. The use of this SG, coupled with Kinect sensor, has been validated to perform functional evaluation of the upper limbs with healthy subjects across lifespan. Twenty-seven FRDA patients were included in the study. Patients were invited to perform upper limb rehabilitation exercises embedded in SG. Motions were recorded by the Kinect and clinically relevant parameters were extracted from the collected motions. We tested if the existence of correlations between the scores from the serious games and the severity of the disease using clinical assessment tools commonly used for FRDA. Results of patients were compared with a group a healthy subjects of similar age. RESULTS: Very highly significant differences were found for time required to perform the exercise (increase of 76%, t(68) = 7.22, P < 0.001) and for accuracy (decrease of 6%, t(68) = - 3.69, P < 0.001) between patients and healthy subjects. Concerning the patients significant correlations were found between age and time (R = 0.65, p = 0.015), accuracy (R = - 0.75, p = 0.004) and the total displacement of upper limbs. (R = 0.55, p = 0.031). Statistically significant correlations were found between the age of diagnosis and speed related parameters. CONCLUSIONS: The results of this study indicate that SG reliably captures motor impairment of FRDA patients due to cerebellar and pyramidal involvement. Results also show that functional evaluation of FRDA patients can be performed during rehabilitation therapy embedded in games with the patient seated in a wheelchair. TRIAL REGISTRATION: The study was approved as a component of the EFACTS study ( Clinicaltrials.gov identifier NCT02069509 , registered May 2010) by the local institutional Ethics Committee (ref. P2010/132). PMID- 30286777 TI - Accelerated vs. conventionally fractionated adjuvant radiotherapy in high-risk head and neck cancer: a meta-analysis. AB - BACKGROUND: Adjuvant radiotherapy in advanced head and neck squamous cell cancer (HNSCC) reduces the risk of local-regional failure and most likely increases the survival rate. Patients at high risk for tumor recurrence may benefit from more aggressive altered fractionation schedules in order to reduce the overall time from surgery to completion of radiotherapy. Here, we reviewed the results of six randomized trials addressing the above hypothesis. METHODS: In the six trials of interest, a total of 988 patients with locally advanced HNSCC were randomly assigned to receive either accelerated or conventionally fractionated adjuvant radiotherapy. Hazard ratios (HR) were extracted from available publications for local-regional control, distant metastasis as well as overall-, cancer specific- and disease-free survival. Meta-analysis of the effect sizes was performed using fixed and random effect models. Acute and late side effects were categorized and summarized for comparison. RESULTS: Accelerated radiotherapy did not improve the loco-regional control (n = 988, HR = 0.740, CI = 0.48-1.13, p = 0.162), progression-free survival (HR = 0.89, CI = 0.76-1.04, p = 0.132) or overall survival (HR = 0.88, CI = 0.75-1.04, p = 0.148) significantly. Acute confluent mucositis occurred with significant higher frequency with accelerated radiotherapy. Late side effects did not differ significantly in either group. CONCLUSION: Accelerated radiotherapy does not result in a significant improvement of loco-regional control or overall survival in high-risk patients. Acute but not late radiation toxicity were more frequent with the accelerated RT technique. In clinical practice accelerated postoperative radiation therapy might be a suitable option only for a subset of patients. PMID- 30286778 TI - Reoperation for isolated rheumatic tricuspid regurgitation. AB - BACKGROUND: The reoperation for isolated tricuspid regurgitation in rheumatic population is rare and still unclear and controversial because of the rarity of publications. The aim of this study was to analyze short and long-term results and outcome of tricuspid valve surgery after left-sided valve surgery in rheumatic patients. METHODS: Twenty six consecutive rheumatic patients who underwent isolated tricuspid valve surgery after left-sided valve surgery between January 2000 and January2017 were retrospectively registered in the study. The mean age was 48.2 +/- 8.6 years with 8.3% as sex-ratio (M/F). EuroSCORE was 6.1 +/- 5 (range 2.5 to 24.1). The mechanism of tricuspid regurgitation was functional and organic in respectively 14 (53.8%) and 12 cases (46.2%). Ten patients (38.5%) had previous tricuspid valve repair. Surgery consisted of 15 ring annuloplasty and 11 tricuspid valve replacement (5 bioprostheses and 6 mechanical prostheses). Follow-up was 96.1% complete, with a mean follow-up of 55.6 +/- 38.8 months (range 1 to 165). RESULTS: The operative mortality rate was 15.4% (n = 4) and the cumulative survival at 1, 5 and 10 years was respectively 80% +/- 8%, 75.6% +/- 8.7% and 67.2% +/- 11.1% with no significant difference at 8 years between tricuspid valve replacement (80% +/- 12.6%) and repair (57.6% +/- 16.1%) (p = 0.5). Multivariable Cox regression analysis revealed that ascites (HR, 5.8; p = 0.01), and right ventricular dysfunction (HR, 0.94; p = 0.001) were predictors of major adverse cardiac events. There were no recurrence of tricuspid regurgitation and no structural or non-structural deterioration of valvular prostheses. CONCLUSION: The reoperation of rheumatic tricuspid regurgitation should be considered before the installation of complications such as right ventricular dysfunction and major signs of right heart failure. Despite the superiority of repair techniques, tricuspid valve replacement should not be banished. PMID- 30286779 TI - Inhibition of STAT3 blocks protein synthesis and tumor metastasis in osteosarcoma cells. AB - BACKGROUND: Osteosarcoma is the most common bone cancer. Despite advances, molecular mechanisms associated with osteosarcoma have not been fully understood. Hence, an effective treatment for osteosarcoma has yet to be developed. Even though signal transducer and activator of transcription3 (STAT3) has been implicated, its role in pathogenesis of osteosarcoma is not fully determined. In this study, we investigated the antitumor effect of napabucasin (NP) (BBI608), an inhibitor of STAT3 on osteosarcoma in vitro and in vivo and studied the underlying molecular mechanism. METHODS: Cell viability, colony formation, apoptosis, tumor growth and metastasis assays were performed to examine the effect of NP on osteosarcoma in vitro and in vivo. Real-time RT-PCR, western analysis, immunofluorescence and reporter assays were used to monitor the expression and activity of proteins and underlying molecular pathways. Protein synthesis, co-immunoprecipitation and CAP binding assays were carried out to understand NP-mediated mechanism of actions in osteosarcoma cells. RESULTS: Our results show that NP treatment decreases cell viability and induces apoptosis in several osteosarcoma cell lines. NP treatment suppresses both expression and phosphorylation of STAT3 in addition to blocking STAT3-mediated transcription and downstream target proteins in osteosarcoma cells. Furthermore, NP inhibits protein synthesis through regulation of the eukaryotic initiation factor 4E (eIF4E) and eIF4E-binding protein 1 (4E-BP1). NP also inhibits the progression of osteosarcoma tumors and metastasis in vivo in an orthotopic tibial model of osteosarcoma. CONCLUSIONS: Taken together, our investigation reveals that NP acts through a novel mechanism and inhibits osteosarcoma growth and metastasis, and could be investigated clinically for treating osteosarcoma patients alone or in combination with other drugs. PMID- 30286780 TI - Growth factor independence 1 expression in myeloma cells enhances their growth, survival, and osteoclastogenesis. AB - BACKGROUND: In spite of major advances in treatment, multiple myeloma (MM) is currently an incurable malignancy due to the emergence of drug-resistant clones. We previously showed that MM cells upregulate the transcriptional repressor, growth factor independence 1 (Gfi1), in bone marrow stromal cells (BMSCs) that induces prolonged inhibition of osteoblast differentiation. However, the role of Gfi1 in MM cells is unknown. METHODS: Human primary CD138+ and BMSC were purified from normal donors and MM patients' bone marrow aspirates. Gfi1 knockdown and overexpressing cells were generated by lentiviral-mediated shRNA. Proliferation/apoptosis studies were done by flow cytometry, and protein levels were determined by Western blot and/or immunohistochemistry. An experimental MM mouse model was generated to investigate the effects of MM cells overexpressing Gfi1 on tumor burden and osteolysis in vivo. RESULTS: We found that Gfi1 expression is increased in patient's MM cells and MM cell lines and was further increased by co-culture with BMSC, IL-6, and sphingosine-1-phosphate. Modulation of Gfi1 in MM cells had major effects on their survival and growth. Knockdown of Gfi1 induced apoptosis in p53-wt, p53-mutant, and p53-deficient MM cells, while Gfi1 overexpression enhanced MM cell growth and protected MM cells from bortezomib-induced cell death. Gfi1 enhanced cell survival of p53-wt MM cells by binding to p53, thereby blocking binding to the promoters of the pro-apoptotic BAX and NOXA genes. Further, Gfi1-p53 binding could be blocked by HDAC inhibitors. Importantly, inoculation of MM cells overexpressing Gfi1 in mice induced increased bone destruction, increased osteoclast number and size, and enhanced tumor growth. CONCLUSIONS: These results support that Gfi1 plays a key role in MM tumor growth, survival, and bone destruction and contributes to bortezomib resistance, suggesting that Gfi1 may be a novel therapeutic target for MM. PMID- 30286781 TI - Predicting microRNA targeting efficacy in Drosophila. AB - BACKGROUND: MicroRNAs (miRNAs) are short regulatory RNAs that derive from hairpin precursors. Important for understanding the functional roles of miRNAs is the ability to predict the messenger RNA (mRNA) targets most responsive to each miRNA. Progress towards developing quantitative models of miRNA targeting in Drosophila and other invertebrate species has lagged behind that of mammals due to the paucity of datasets measuring the effects of miRNAs on mRNA levels. RESULTS: We acquired datasets suitable for the quantitative study of miRNA targeting in Drosophila. Analyses of these data expanded the types of regulatory sites known to be effective in flies, expanded the mRNA regions with detectable targeting to include 5' untranslated regions, and identified features of site context that correlate with targeting efficacy in fly cells. Updated evolutionary analyses evaluated the probability of conserved targeting for each predicted site and indicated that more than a third of the Drosophila genes are preferentially conserved targets of miRNAs. Based on these results, a quantitative model was developed to predict targeting efficacy in insects. This model performed better than existing models, and it drives the most recent version, v7, of TargetScanFly. CONCLUSIONS: Our evolutionary and functional analyses expand the known scope of miRNA targeting in flies and other insects. The existence of a quantitative model that has been developed and trained using Drosophila data will provide a valuable resource for placing miRNAs into gene regulatory networks of this important experimental organism. PMID- 30286783 TI - Autosomal-dominant transthyretin (TTR)-related amyloidosis is not a frequent CMT2 neuropathy "in disguise". AB - Transthyretin (TTR)-related familial amyloid polyneuropathy (TTR-FAP) is a life threatening autosomal dominant, systemic disease. First symptoms usually occur from the second to over sixth decade of life with a length-dependent axonal neuropathy with prominent involvement of the small fibers and multi-organ systemic failure.Early diagnosis is pivotal for effective therapeutic options, but it is hampered by the heterogeneity of the clinical spectrum which can lead to misdiagnosis with other neurological condition/disorder such as axonal sensory motor neuropathy (CMT2) as described in literature.The aim of our study was to search for TTR mutations in a large cohort of selected undiagnosed axonal sensory motor neuropathy patients to establish if misdiagnosis is frequent or rare in the Italian population.No TTR pathogenic variants were found in our cohort. In conclusion, our study shows that TTR testing not should be straightforward recommended in CMT2 patients but only when "red flags" TTR's features are present. PMID- 30286782 TI - Maternal breast cancer risk in relation to birthweight and gestation of her offspring. AB - BACKGROUND: Parity and age at first pregnancy are well-established risk factors for breast cancer, but the effects of other characteristics of pregnancies are uncertain and the literature is inconsistent. METHODS: In a cohort of 83,451 parous women from the general population of the UK, which collected detailed information on each pregnancy and a wide range of potential confounders, we investigated the associations of length of gestation and birthweight of offspring in a woman's pregnancies with her breast cancer risk, adjusting for a full range of non-reproductive as well as reproductive risk factors unlike in previous large studies. RESULTS: Gestation of the first-born offspring was significantly inversely related to the risk of pre-menopausal breast cancer (p trend = 0.03; hazard ratio (HR) for 26-31 compared with 40-41 weeks, the baseline group, = 2.38, 95% confidence interval (CI) 1.26-4.49), and was borderline significantly related to risk of breast cancer overall (p trend = 0.05). Risk was significantly raised in mothers of high birthweight first-born (HR for breast cancer overall = 1.53, 95% CI 1.06-2.21 for >= 4500 g compared with 3000-3499 g, the baseline group). For gestation and birthweight of most recent birth, there were no clear effects. Analyses without adjustment for confounders (other than age) gave similar results. CONCLUSIONS: Our data add to evidence that short gestation pregnancies may increase the risk of breast cancer, at least pre-menopausally, perhaps by hormonal stimulation and breast proliferation early in pregnancy without the opportunity for the differentiation that occurs in late pregnancy. High birthweight first pregnancies may increase breast cancer risk, possibly through the association of birthweight with oestrogen and insulin-like growth factor 1 levels. PMID- 30286785 TI - Counseling practice of community pharmacists for diabetes mellitus patients in Addis Ababa, Ethiopia. AB - OBJECTIVE: Pharmacists monitor diabetic patients more often than any other healthcare providers. It is important that they have appropriate counseling practice on diabetes mellitus management. The aim of this study is to assess the counseling practice of community pharmacists for diabetes mellitus patients in Addis Ababa, Ethiopia. RESULTS: Among 300 community pharmacy professionals, 58.3% were male. Nearly half of the community pharmacy professionals delivered appropriate counselling service on the appropriate time to administer each oral anti-diabetic drug and missed oral dose. Only 15.3% of the community pharmacy professionals gave proper counselling on the importance of continuous screening for nephropathy, retinopathy, and neuropathy. PMID- 30286784 TI - The Italian neuromuscular registry: a coordinated platform where patient organizations and clinicians collaborate for data collection and multiple usage. AB - BACKGROUND: The worldwide landscape of patient registries in the neuromuscular disease (NMD) field has significantly changed in the last 10 years, with the international TREAT-NMD network acting as strong driver. At the same time, the European Medicines Agency and the large federations of rare disease patient organizations (POs), such as EURORDIS, contributed to a great cultural change, by promoting a paradigm shift from product-registries to patient-centred registries. In Italy, several NMD POs and Fondazione Telethon undertook the development of a TREAT-NMD linked patient registry in 2009, with the referring clinical network providing input and support to this initiative through the years. This article describes the outcome of this joint effort and shares the experience gained. METHODS: The Italian NMD registry is based on an informatics technology platform, structured according to the most rigorous legal national and European requirements for management of patient sensitive data. A user-friendly web interface allows both direct patients and clinicians' participation. The platform's design permits expansion to incorporate new modules and new registries, and is suitable of interoperability with other international efforts. RESULTS: When the Italian NMD Registry was initiated, an ad hoc legal entity (NMD Registry Association) was devised to manage registries' data. Currently, several disease-specific databases are hosted on the platform. They collect molecular and clinical details of individuals affected by Duchenne or Becker muscular dystrophy, Charcot-Marie-Tooth disease, transthyretin type-familial amyloidotic polyneuropathy, muscle glycogen storage disorders, spinal and bulbar muscular atrophy, and spinal muscular atrophy. These disease-specific registries are at different stage of development, and the NMD Registry itself has gone through several implementation steps to fulfil different technical and governance needs. The new governance model is based on the agreement between the NMD Registry Association and the professional societies representing the Italian NMD clinical network. Overall, up to now the NMD registry has collected data on more than 2000 individuals living with a NMD condition. CONCLUSIONS: The Italian NMD Registry is a flexible platform that manages several condition-specific databases and is suitable to upgrade. All stakeholders participate in its management, with clear roles and responsibilities. This governance model has been key to its success. In fact, it favored patient empowerment and their direct participation in research, while also engaging the expert clinicians of the Italian network in the collection of accurate clinical data according to the best clinical practices. PMID- 30286787 TI - The effects of dietary instruction on cardiovascular risk markers after smoking cessation: study protocol for a multicenter randomized controlled trial in Japan. AB - BACKGROUND: Weight gain frequently occurs after smoking cessation (SC); the risk of new-onset diabetes mellitus increases for several years after SC. However, no large-scale, randomized controlled trials have examined the effects of nutritional guidance on post-SC cardiovascular risk. The current trial will enroll individuals who successfully quit smoking with the help of a SC clinic and who gain weight, to determine the effects of nutritional guidance on cardiovascular, glucose, and lipid metabolism biomarkers. METHODS/DESIGN: This is a multicenter, prospective, parallel-group, randomized controlled trial. Some 250 individuals who successfully quit smoking with the help of a SC clinic and who gain weight (an increase of >= 1.25% Body Mass Index (BMI) between the first and the fifth visit to the SC clinic) will be enrolled within 1 month of the final (fifth) visit to the SC clinic. These participants will be randomly assigned to an intervention group (125 individuals receiving nutritional guidance) or a control group (125 individuals not receiving nutritional guidance). A registered dietitian will provide nutritional guidance once every 3 months for a total of three sessions. The primary endpoint for this trial will be the level of adiponectin, a predictor of cardiovascular risk that reflects weight and smoking status. Secondary endpoints will be levels of cardiovascular, glucose, and lipid metabolism biomarkers, BMI, abdominal circumference, and the percentage of individuals who quit smoking for a prolonged period. DISCUSSION: This trial will determine the benefits of nutritional guidance with respect to post-SC weight gain. The findings should provide useful information for devising a quality protocol for SC education to prevent cardiovascular disease. TRIAL REGISTRATION: The study is registered at the University Hospital Medical Information Network Clinical Trials Registry ( UMIN000030282 ). Registered on 6 December 2017. PMID- 30286786 TI - The burden of low back pain among undergraduate physiotherapy students at the University of Zimbabwe: a cross-sectional study. AB - OBJECTIVE: Globally, non-specific low back pain (NSLBP) is a common cause of morbidity in all people including physiotherapy students. However, no study has investigated the problem among undergraduate physiotherapy students in Zimbabwe. This study was conducted, therefore, to provide evidence of the prevalence, clinical characteristics and consequences of recurrent NSLBP among undergraduate physiotherapy students at the University of Zimbabwe. RESULTS: The final sample had 90 participants, giving a study response rate of 97.8%. The median age of the participants was 22 years. The lifetime prevalence of NSLBP was 56.7% (n = 51) and the mean age of onset for NSLBP was 19.7 years (SD = 1.64 years). The 12 month prevalence of recurrent NSLBP was 38.9% (n = 35). Of the 35, 20 (57.1%) experienced at least three episodes in the last 12 months. Each episode lasted for 1-7 days in most participants (n = 31, 88.6%). The mean intensity of recurrent episodes was 3.37 (SD = 1.43) measured on Visual Analogue Scale. Only 7 (20%) experienced at least one functional limitation due to recurrent NSLBP. Additionally, only 2 (5.7%) sought medical treatment for the pain. However, 6 (17.1%) had to be absent from the university secondary to recurrent NSLBP. PMID- 30286788 TI - A novel long noncoding RNA HOXC-AS3 mediates tumorigenesis of gastric cancer by binding to YBX1. AB - BACKGROUND: Recently, increasing evidence shows that long noncoding RNAs (lncRNAs) play a significant role in human tumorigenesis. However, the function of lncRNAs in human gastric cancer remains largely unknown. RESULTS: By using publicly available expression profiling data from gastric cancer and integrating bioinformatics analyses, we screen and identify a novel lncRNA, HOXC-AS3. HOXC AS3 is significantly increased in gastric cancer tissues and is correlated with clinical outcomes of gastric cancer. In addition, HOXC-AS3 regulates cell proliferation and migration both in vitro and in vivo. RNA-seq analysis reveals that HOXC-AS3 knockdown preferentially affects genes that are linked to proliferation and migration. Mechanistically, we find that HOXC-AS3 is obviously activated by gain of H3K4me3 and H3K27ac, both in cells and in tissues. RNA pull down mass spectrometry analysis identifies that YBX1 interacts with HOXC-AS3, and RNA-seq analysis finds a marked overlap in genes differentially expressed after YBX1 knockdown and those transcriptionally regulated by HOXC-AS3, suggesting that YBX1 participates in HOXC-AS3-mediated gene transcriptional regulation in the tumorigenesis of gastric cancer. CONCLUSIONS: Together, our data demonstrate that abnormal histone modification-activated HOXC-AS3 may play important roles in gastric cancer oncogenesis and may serve as a target for gastric cancer diagnosis and therapy. PMID- 30286789 TI - Empowering the detection of ChIP-seq "basic peaks" (bPeaks) in small eukaryotic genomes with a web user-interactive interface. AB - OBJECTIVE: bPeaks is a peak calling program to detect protein DNA-binding sites from ChIPseq data in small eukaryotic genomes. The simplicity of the bPeaks method is well appreciated by users, but its use via an R package is challenging and time-consuming for people without programming skills. In addition, user feedback has highlighted the lack of a convenient way to carefully explore bPeaks result files. In this context, the development of a web user interface represents an important added value for expanding the bPeaks user community. RESULTS: We developed a new bPeaks application (bPeaks App). The application allows the user to perform all the peak-calling analysis steps with bPeaks in a few mouse clicks via a web browser. We added new features relative to the original R package, particularly the possibility to import personal annotation files to compare the location of the detected peaks with specific genomic elements of interest of the user, in any organism, and a new organization of the result files which are directly manageable via a user-interactive genome browser. This significantly improves the ability of the user to explore all detected basic peaks in detail. PMID- 30286790 TI - Lessons from a comparison of immuno-chromatographic and chemiluminescent micro particle immunoassay in the diagnosis of syphilis. AB - OBJECTIVE: To synthesize lessons from comparison of results obtained from the immuno-chromatographic SD Bioline testing method and the chemiluminescent micro particle immunoassay Architect in the diagnosis of syphilis at Livingstone Central hospital laboratory. RESULTS: The specificity and sensitivity of SD Bioline syphilis 3.0 against the chemiluminescent immunoassay using the Architect syphilis Treponema pallidum (TP) was 85.3% and 91.3% respectively with substantial agreement between the two test methods (88%, K = 0.76; p < 0.0005). We recommend further comprehensive study with a larger sample size and clinical details to ascertain the validity of our findings. We also recommend using a non treponemal test with the current treponemal tests being used to aid diagnosis. PMID- 30286791 TI - Deep proteomic network analysis of Alzheimer's disease brain reveals alterations in RNA binding proteins and RNA splicing associated with disease. AB - BACKGROUND: The complicated cellular and biochemical changes that occur in brain during Alzheimer's disease are poorly understood. In a previous study we used an unbiased label-free quantitative mass spectrometry-based proteomic approach to analyze these changes at a systems level in post-mortem cortical tissue from patients with Alzheimer's disease (AD), asymptomatic Alzheimer's disease (AsymAD), and controls. We found modules of co-expressed proteins that correlated with AD phenotypes, some of which were enriched in proteins identified as risk factors for AD by genetic studies. METHODS: The amount of information that can be obtained from such systems-level proteomic analyses is critically dependent upon the number of proteins that can be quantified across a cohort. We report here a new proteomic systems-level analysis of AD brain based on 6,533 proteins measured across AD, AsymAD, and controls using an analysis pipeline consisting of isobaric tandem mass tag (TMT) mass spectrometry and offline prefractionation. RESULTS: Our new TMT pipeline allowed us to more than double the depth of brain proteome coverage. This increased depth of coverage greatly expanded the brain protein network to reveal new protein modules that correlated with disease and were unrelated to those identified in our previous network. Differential protein abundance analysis identified 350 proteins that had altered levels between AsymAD and AD not caused by changes in specific cell type abundance, potentially reflecting biochemical changes that are associated with cognitive decline in AD. RNA binding proteins emerged as a class of proteins altered between AsymAD and AD, and were enriched in network modules that correlated with AD pathology. We developed a proteogenomic approach to investigate RNA splicing events that may be altered by RNA binding protein changes in AD. The increased proteome depth afforded by our TMT pipeline allowed us to identify and quantify a large number of alternatively spliced protein isoforms in brain, including AD risk factors such as BIN1, PICALM, PTK2B, and FERMT2. Many of the new AD protein network modules were enriched in alternatively spliced proteins and correlated with molecular markers of AD pathology and cognition. CONCLUSIONS: Further analysis of the AD brain proteome will continue to yield new insights into the biological basis of AD. PMID- 30286792 TI - Tri-methylation of ATF7IP by G9a/GLP recruits the chromodomain protein MPP8. AB - BACKGROUND: G9a and the related enzyme GLP were originally identified as histone lysine methyltransferases and then shown to also methylate several other non histone proteins. RESULTS: Here, we performed a comprehensive screen to identify their substrates in mouse embryonic stem cells (mESCs). We identified 59 proteins, including histones and other known substrates. One of the identified substrates, activating transcriptional factor 7-interacting protein 1 (ATF7IP), is tri-methylated at a histone H3 lysine 9 (H3K9)-like mimic by the G9a/GLP complex, although this complex mainly introduces di-methylation on H3K9 and DNA ligase 1 (LIG1) K126 in cells. The catalytic domain of G9a showed a higher affinity for di-methylated lysine on ATF7IP than LIG1, which may create different methylation levels of different substrates in cells. Furthermore, we found that M phase phosphoprotein 8 (MPP8), known as a H3K9me3-binding protein, recognizes methylated ATF7IP via its chromodomain. MPP8 is also a known component of the human silencing hub complex that mediates silencing of transgenes via SETDB1 recruitment, which is a binding partner of ATF7IP. Although the interaction between ATF7IP and SETDB1 does not depend on ATF7IP methylation, we found that induction of SETDB1/MPP8-mediated reporter-provirus silencing is delayed in mESCs expressing only an un-methylatable mutant of ATF7IP. CONCLUSIONS: Our findings provide new insights into the roles of lysine methylation in non-histone substrates which are targeted by the G9a/GLP complex and suggest a potential function of ATF7IP methylation in SETDB1/MPP8-mediated transgene silencing. PMID- 30286793 TI - E2F2 directly regulates the STAT1 and PI3K/AKT/NF-kappaB pathways to exacerbate the inflammatory phenotype in rheumatoid arthritis synovial fibroblasts and mouse embryonic fibroblasts. AB - BACKGROUND: Expression of E2F transcription factor 2 (E2F2), a transcription factor related to the cell cycle, is abnormally high in rheumatoid arthritis synovial fibroblasts (RASFs). Deregulated expression of E2F2 leads to abnormal production of proinflammatory cytokines, such as interleukin (IL)-1alpha, IL 1beta, and tumor necrosis factor (TNF)-alpha in RASFs. However, the underlying mechanism by which E2F2 regulates expression of IL-1alpha, IL-1beta, and TNF alpha has not been fully elucidated. This study aimed to elucidate this mechanism and confirm the pathological roles of E2F2 in rheumatoid arthritis (RA). METHODS: E2f2 knockout (KO) and wild-type (WT) mice were injected with collagen to induce RA. Cytokine production was assessed by quantitative real-time polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA). Western blot and qRT-PCR were performed to evaluate the effect of E2F2 on signaling pathway activity. Chromatin immunoprecipitation (ChIP)-PCR and luciferase assays were used to detect the transcriptional activity of target genes of E2F2. Nuclear translocation of STAT1 and p65 were assayed by Western blot, co immunoprecipitation (co-IP), and immunofluorescence experiments. RESULTS: The occurrence and severity of collagen-induced arthritis were decreased in E2f2-KO mice compared with WT mice. The expression of IL-1alpha, IL-1beta, and TNF-alpha was also suppressed in mouse embryonic fibroblasts (MEFs) from E2f2-KO mice and RASFs with E2F2 knocked down. Mechanistically, we found that E2F2 can upregulate the expression of STAT1 and MyD88 through direct binding to their promoters, facilitate the formation of STAT1/MyD88 complexes, and consequently activate AKT. However, silencing STAT1/MyD88 or inactivating AKT significantly attenuated the induction of IL-1alpha, IL-1beta, and TNF-alpha caused by the introduction of E2F2. CONCLUSIONS: This study confirms the pathological role of E2F2 in RA and found that the E2F2-STAT1/MyD88-Akt axis is closely related with the inflammatory phenotype in RASFs. PMID- 30286794 TI - Cell-gel interactions of in-gel propagating bacteria. AB - OBJECTIVE: Our immediate objective is to test the data-suggested possibility that in-agarose gel bacterial propagation causes gel fiber dislocation and alteration of cell distribution. We also test the further effect of lowering water activity. We perform these tests with both Gram-negative and Gram-positive bacteria. Data are obtained via electron microscopy of thin sections, which provides the first images of both bacteria and gel fibers in gel-supported bacterial lawns. The long term objective is analysis of the effects of in-gel propagation on the DNA packaging of phages. RESULTS: We find that agarose gel-supported cells in lawns of Escherichia coli and Lysinibacillus (1) are primarily in clusters that increase in size with time and are surrounded by gel fibers, and (2) sometimes undergo gel-induced, post-duplication rotation and translation. Bacterial growth induced dislocation of gel fibers is observed. One reason for clustering is that clustering promotes growth by increasing the growth-derived force applied to the gel fibers. Reactive force exerted by gel on cells explains cell movement. Finally, addition to growth medium of 0.94 M sucrose causes cluster-associated E. coli cells to become more densely packed and polymorphic. Shape is determined, in part, by neighboring cells, a novel observation to our knowledge. PMID- 30286796 TI - Iceberg of workplace violence in health sector of Bangladesh. AB - OBJECTIVES: 'Negligence of Physicians' and 'Wrong Treatment' have become commonly used phrases in print and electronic media of Bangladesh, while violence against healthcare workers has always been under-reported. Unfortunately, there is little evidence regarding physical violence against healthcare workers, while there is no data on the magnitude of psychological violence. The objective of this study was to quantify and explore the magnitude of workplace violence in health sector of Bangladesh to guide future research and adopt preventive policies. RESULTS: The Majority (96%, n = 54) of the violence cases were physical in nature and 91% violence (n = 51) took place in public healthcare settings. More than one-third (39%) of the violence cases occurred at primary healthcare level and one-third (39%) at tertiary healthcare level. It was mostly (61%) the entry-level physicians who were affected by violence. The report reveals the tip of the iceberg of workplace violence in health sector of Bangladesh. Further studies should be undertaken to assess the prevalence, magnitude, and associated factors for workplace violence against healthcare workers. PMID- 30286795 TI - The methylome of the marbled crayfish links gene body methylation to stable expression of poorly accessible genes. AB - BACKGROUND: The parthenogenetic marbled crayfish (Procambarus virginalis) is a novel species that has rapidly invaded and colonized various different habitats. Adaptation to different environments appears to be independent of the selection of genetic variants, but epigenetic programming of the marbled crayfish genome remains to be understood. RESULTS: Here, we provide a comprehensive analysis of DNA methylation in marbled crayfish. Whole-genome bisulfite sequencing of multiple replicates and different tissues revealed a methylation pattern that is characterized by gene body methylation of housekeeping genes. Interestingly, this pattern was largely tissue invariant, suggesting a function that is unrelated to cell fate specification. Indeed, integrative analysis of DNA methylation, chromatin accessibility and mRNA expression patterns revealed that gene body methylation correlated with limited chromatin accessibility and stable gene expression, while low-methylated genes often resided in chromatin with higher accessibility and showed increased expression variation. Interestingly, marbled crayfish also showed reduced gene body methylation and higher gene expression variability when compared with their noninvasive mother species, Procambarus fallax. CONCLUSIONS: Our results provide novel insights into invertebrate gene body methylation and its potential role in adaptive gene regulation. PMID- 30286797 TI - Physical Activity after Cardiac EventS (PACES) - a group education programme with subsequent text-message support designed to increase physical activity in individuals with diagnosed coronary heart disease: study protocol for a randomised controlled trial. AB - BACKGROUND: Coronary heart disease (CHD) represents approximately 13% of deaths worldwide and is the leading cause of death in the UK with considerable associated health care costs. After a CHD event, timely cardiac rehabilitation optimises patient outcomes. However, a high percentage of these services do not meet necessary performance indicators such as course length and follow-up attendance. Uptake of such services is only 50% in UK patients and support provided 12 months after an event is often limited. To delay and prevent further CHD events leading to hospitalisation, supplementary self-management strategies such as group education, are necessary. METHODS: This is a single-centre, randomised controlled trial (RCT) recruiting participants (n = 290) aged >=18 years who are 12 to 48 months post diagnosis of a CHD-related cardiac event (myocardial infarction, angina and any other acute coronary syndrome). The study aims to implement a structured education programme, with text-message support over 12 months, and identify whether delivery of the programme, to individuals who have a history of a cardiac event, would be an effective and cost-effective strategy for increasing walking. The primary outcome, objectively measured average daily physical activity, specifically step count through walking activity, is assessed using the wrist-worn GENEActiv accelerometer at baseline, 6 and 12 months. Secondary outcomes at 12 months include cardiovascular risk factors such as smoking status, blood pressure, lipid profile, glycated haemoglobin (HbA1c), obesity, self-efficacy, quality of life, physical activity and physical function. Participants are randomised to either the control group receiving standard care and a physical activity information leaflet, or the intervention group whose partcipants receive the leaflet and are invited to attend two group-based structured education sessions. These encourage participants to adopt and maintain healthy behaviours and self-manage their lifestyle. They are delivered approximately 2 weeks apart by trained facilitators and reinforced via subsequent text-message support. DISCUSSION: To our knowledge, this is the first trial designed to assess the effectiveness of a group education programme 12 to 48 months after a CHD event diagnosis. If successful, the PACES programme could be translated into effective post-operative cardiac care and complement the current post-operative services available.

PMID- 30286798 TI - Optimizing huddle engagement through leadership and problem-solving within primary care: A study protocol for a cluster randomized trial. AB - BACKGROUND: Team-based care has been identified as a key component in transforming primary care. An important factor in implementing team-based care is the requirement for teams to have daily huddles. During huddles, the care team, comprising physicians, nurses, and administrative staff, come together to discuss their daily schedules, track problems, and develop countermeasures to fix these problems. However, the impact of these huddles on staff burnout over time and patient outcomes are not clear. Further, there are challenges to implementing huddles in fast-paced primary care clinics. We will test whether the impact of a behavioral intervention of leadership training and problem-solving during the daily huddling process will result in higher consistent huddling in the intervention arm and result in higher team morale, reduced burnout, and improved patient outcomes. METHODS/DESIGN: We will conduct a care-team-level cluster randomized trial within primary care practices in two Midwestern states. The intervention will comprise a 1-day training retreat for leaders of primary care teams, biweekly sessions between huddle optimization coaches and members of the primary care teams, as well as coaching site visits at 30 and 100 days post intervention. This behavioral intervention will be compared to standard care, in which care teams have huddles without any support or training. Surveys of primary care team members will be administered at baseline (prior to training), 100 days (for the intervention arm only), and 180 days to assess team dynamics. The primary outcome of this trial will be team morale. Secondary outcomes will assess the impact of this intervention on clinician burnout, patient satisfaction, and quality of care. DISCUSSION: This trial will provide evidence on the impact of a behavioral intervention to implement huddles as a key component of team-based care models. Knowledge gained from this trial will be critical to broader deployment and successful implementation of team-based care models. TRIAL REGISTRATION: Clinicaltrials.gov , NCT03062670 .

AB - BACKGROUND: Anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV) is a group of life-threatening autoimmune diseases. The epidemiological data on AAV in China are limited. The aim of the present study is to investigate the frequency, geographical distribution, and ethnic distribution of AAV in hospitalized patients in China, and its association with environmental pollution. METHODS: We investigated the hospitalized patients in a national inpatient database covering 54.1% tertiary hospitals in China from 2010 to 2015. Diagnosis of AAV was extracted according to the definition of International Classification of Diseases (ICD)-10 codes and free text. Variables from the front page of inpatient records were collected and analyzed, including frequency, geographic distribution, demographic characteristics and seasonal variations of AAV. The association between various environmental pollutants and frequency of AAV was further analyzed. RESULTS: Among 43.7 million inpatients included in the study period, 0.250/00 (10,943) were diagnosed as having AAV. The frequency of AAV was relatively stable during the study period (from 0.340/00 in 2010 to 0.270/00 in 2015). The proportion of AAV increased with latitude (0.440/00 in Northern China and 0.270/00 in Southern China in 2015). Hospitalizations were mostly observed in winter (30.2%). The Dong population, an ethnic minority of the Chinese population, had the highest frequency of patients with AAV (0.670/00). We also found a positive association between the exposure to carbon monoxide and the frequency of AAV (R2 = 0.172, p = 0.025). In Yunnan province, the frequency of AAV increased 1.37-fold after the Zhaotong earthquake, which took place in 2014. CONCLUSIONS: Our present investigation of hospitalized patients provided epidemiological information on AAV in China for the first time. A spatial and ethnic clustering trend and an association between pollution and the frequency of AAV were observed. PMID- 30286801 TI - Time to death and risk factors among tuberculosis patients in Northern Ethiopia. AB - OBJECTIVE: The main objective of this study was to assess time to death and associated risk factors among tuberculosis (TB) patients. RESULTS: A total of 769 TB patients were studied and of those, 87 (11.3%) patients died. All of the deaths occurred within 7 months of anti-tuberculosis therapy. Extra-pulmonary TB (AHR = 17.376, 95% CI; 3.88-77.86, p < 0.001) as compared to pulmonary TB and cotrimoxazole prophylaxis therapy (CPT) (AHR = 0.15, 95% CI; 0.03-0.74, p = 0.02) were found to be the predictors of mortality. We noticed higher rates of mortality. Extra-pulmonary TB patients have high risk and TB-HIV co-infected patients who received CPT have low risk of death. Improving early diagnosis of extra-pulmonary TB and early CPT initiation of TB-HIV co-infected patients could minimize patient's mortality. PMID- 30286800 TI - A new blood parasite of leaf warblers: molecular characterization, phylogenetic relationships, description and identification of vectors. AB - BACKGROUND: Blood parasites of the genus Haemoproteus Kruse, 1890 are cosmopolitan, might be responsible for mortality in non-adapted birds, and often kill blood-sucking insects. However, this group remains insufficiently investigated in the wild. This is particularly true for the parasites of leaf warblers of the Phylloscopidae Alstrom, Ericson, Olsson & Sundberg the common small Old World passerine birds whose haemoproteid parasite diversity and vectors remain poorly studied. This study reports a new species of Haemoproteus parasitizing leaf warblers, its susceptible vector and peculiar phylogenetic relationships with other haemoproteids. METHODS: Wood warblers (Phylloscopus sibilatrix Bechstein) were caught in Lithuania during spring migration, and blood films were examined microscopically. Laboratory reared Culicoides nubeculosus Meigen were exposed experimentally by allowing them to take blood meals on one individual harbouring mature gametocytes of the new Haemoproteus species (lineage hPHSIB2). To follow sporogonic development, the engorged insects were dissected at intervals. The parasite lineage was distinguished using sequence data, and morphological analysis of blood and sporogonic stages was carried out. Bayesian phylogeny was constructed in order to determine the phylogenetic relationships of the new parasite with other haemoproteids. RESULTS: Haemoproteus (Parahaemoproteus) homopalloris n. sp. was common in wood warblers sampled after arrival to Europe from their wintering grounds in Africa. The new parasite belongs to a group of avian haemoproteid species with macrogametocytes possessing pale staining cytoplasm. All species of this group clustered together in the phylogenetic analysis, indicating that intensity of the cytoplasm staining is a valuable phylogenetic character. Laboratory-reared biting midges C. nubeculosus readily supported sporogony of new infections. Phylogenetic analysis corroborated vector experiments, placing the new parasite in the clade of Haemoproteus (Parahaemoproteus) parasites transmitted by biting midges. CONCLUSIONS: Haemoproteus homopalloris n. sp. is the third haemoproteid, which is described from and is prevalent in wood warblers. Phylogenetic analysis identified a clade containing seven haemoproteids, which are characterised by pale staining of the macrogametocyte cytoplasm and with ookinetes maturing exceptionally rapidly (between 1 to 1.5 h after exposure to air). Both these features may represent valuable phylogenetic characters. Studies targeting mechanisms of sporogonic development of haemoproteids remain uncommon and should be encouraged. Culicoides nubeculosus is an excellent experimental vector of the new parasite species. PMID- 30286804 TI - A robust cell culture system for large scale feeder cell-free expansion of human breast epithelial progenitors. AB - BACKGROUND: Normal human breast epithelial cells are maintained by the proliferation and differentiation of different human breast epithelial progenitors (HBEPs). However, these progenitor subsets can only be obtained at low frequencies, limiting their further characterization. Recently, it was reported that HBEPs can be minimally expanded in Matrigel cocultures with stromal feeder cells. However, variability of generating healthy feeder cells significantly impacts the effective expansion of HBEPs. METHODS: Here, we report a robust feeder cell-free culture system for large-scale expansion of HBEPs in two-dimensional cultures. RESULTS: Using this cell culture system HBEPs can be exponentially expanded as bulk cultures. Moreover, purified HBEP subtypes can also be separately expanded using our cell culture system. The expanded HBEPs retain their undifferentiated phenotype and form distinct epithelial colonies in colony forming cell assays. CONCLUSIONS: The availability of a culture system enabling the large-scale expansion of HBEPs facilitates their application to screening platforms and other cell-based assays.

PMID- 30286802 TI - Multiple paralogues of alpha-SNAP in Giardia lamblia exhibit independent subcellular localization and redistribution during encystation and stress. AB - BACKGROUND: The differently-diverged parasitic protist Giardia lamblia is known to have minimal machinery for vesicular transport. Yet, it has three paralogues of SNAP, a crucial component that together with NSF brings about disassembly of the cis-SNARE complex formed following vesicle fusion to target membranes. Given that most opisthokont hosts of this gut parasite express only one alpha-SNAP, this study was undertaken to determine whether these giardial SNAP proteins have undergone functional divergence. RESULTS: All three SNAP paralogues are expressed in trophozoites, encysting trophozoites and cysts. Even though one of them clusters with gamma-SNAP sequences in a phylogenetic tree, functional complementation analysis in yeast indicates that all the three proteins are functionally orthologous to alpha-SNAP. Localization studies showed a mostly non overlapping distribution of these alpha-SNAPs in trophozoites, encysting cells and cysts. In addition, two of the paralogues exhibit substantial subcellular redistribution during encystation, which was also seen following exposure to oxidative stress. However, the expression of the three genes remained unchanged during this redistribution process. There is also a difference in the affinity of each of these alpha-SNAP paralogues for GlNSF. CONCLUSIONS: None of the genes encoding the three alpha-SNAPs are pseudogenes and the encoded proteins are likely to discharge non-redundant functions in the different morphological states of G. lamblia. Based on the difference in the interaction of individual alpha SNAPs with GlNSF and their non-overlapping pattern of subcellular redistribution during encystation and under stress conditions, it may be concluded that the three giardial alpha-SNAP paralogues have undergone functional divergence. Presence of one of the giardial alpha-SNAPs at the PDRs of flagella, where neither GlNSF nor any of the SNAREs localize, indicates that this alpha-SNAP discharges a SNARE-independent role in this gut pathogen. PMID- 30286805 TI - Burkitt lymphoma of the ovaries mimicking sepsis: a case report and review of the literature. AB - BACKGROUND: It is not unusual for systemic diseases to mimic sepsis and, in any case, the clinician should thoroughly investigate this possibility. CASE PRESENTATION: We present the case of a 21-year-old Greek woman who presented to the Intensive Care Unit of our hospital with severe septic shock - multiple organ failure as a result of a suspected gynecological infection of the ovaries. An immediate improvement of her clinical condition in combination with strong clinical suspicion and negative cultures led to the differential diagnosis of diseases other than sepsis. Based on the results of the biopsies that were obtained by research laparotomy, our patient suffered from primary Burkitt ovarian lymphoma. Her clinical condition improved with supportive treatment and chemotherapy. Chemotherapy is the dominant treatment for Burkitt's lymphoma, while surgery or radiotherapy has no place. CONCLUSIONS: All intensivists should be aware of clinical conditions that mimic sepsis as early diagnosis can lead to appropriate therapy and avoid unnecessary diagnostic tests and antibiotic abuse. PMID- 30286806 TI - Inverse association between estrogen receptor-alpha DNA methylation and breast composition in adolescent Chilean girls. AB - BACKGROUND: Estrogen receptor-alpha (ER-alpha) is a transcriptional regulator, which mediates estrogen-dependent breast development, as well as breast tumorigenesis. The influence of epigenetic regulation of ER-alpha on adolescent breast composition has not been previously studied and could serve as a marker of pubertal health and susceptibility to breast cancer. We investigated the association between ER-alpha DNA methylation in leukocytes and breast composition in adolescent Chilean girls enrolled in the Growth and Obesity Cohort Study (GOCS) in Santiago, Chile. Breast composition (total breast volume (BV; cm3), fibroglandular volume (FGV; cm3), and percent fibroglandular volume (%FGV)) was measured at breast Tanner stage 4 (B4). ER-alpha promoter DNA methylation was assessed by pyrosequencing in blood samples collected at breast Tanner stages 2 (B2; n = 256) and B4 (n = 338). RESULTS: After adjusting for fat percentage at breast density measurement, ER-alpha methylation at B2, and cellular heterogeneity, we observed an inverse association between B4 average ER-alpha DNA methylation and BV and FGV. Geometric mean BV was 15% lower (95% CI: - 28%, - 1%) among girls in the highest quartile of B4 ER-alpha methylation (6.96-23.60%) relative to the lowest (0.78-3.37%). Similarly, FGV was 19% lower (95% CI: - 33%, - 2%) among girls in the highest quartile of B4 ER-alpha methylation relative to the lowest. The association between ER-alpha methylation and breast composition was not significantly modified by body fat percentage and was not influenced by pubertal timing. CONCLUSIONS: These findings suggest that the methylation profile of ER-alpha may modulate adolescent response to estrogen and breast composition, which may influence breast cancer risk in adulthood. PMID- 30286808 TI - The therapeutic potential of bone marrow mesenchymal stem cells in premature ovarian failure. AB - With the development of regenerative medicine, a variety of mesenchymal stem cells (MSCs) are increasingly considered for the treatment of premature ovarian failure (POF). Reportedly, bone marrow-derived MSCs (BMSCs) improve the ovarian reserve, which mainly depends on homing and paracrine activities. Furthermore, paracrine factors secreted by these stem cells play an important role in ovarian recovery. Relevant studies indicate that BMSC transplantation has some positive effects on the treatment of POF in animals, but BMSCs are not widely applied in clinical therapy. Clinical trials are ongoing despite the fact that several patients experiencing BMSC transplantation recover their normal menstrual cycles and even give birth to babies. In this review, we discuss the possible therapeutic mechanisms of BMSCs for POF, migration, antiapoptosis, antifibrosis, angiogenesis, anti-inflammation, immunoregulation, and oxidative stress, which provide the theoretical basis for further study and clinical therapy. PMID- 30286807 TI - Pediatric asthma comprises different phenotypic clusters with unique nasal microbiotas. AB - BACKGROUND: Pediatric asthma is the most common chronic childhood disease in the USA, currently affecting ~ 7 million children. This heterogeneous syndrome is thought to encompass various disease phenotypes of clinically observable characteristics, which can be statistically identified by applying clustering approaches to patient clinical information. Extensive evidence has shown that the airway microbiome impacts both clinical heterogeneity and pathogenesis in pediatric asthma. Yet, so far, airway microbiotas have been consistently neglected in the study of asthma phenotypes. Here, we couple extensive clinical information with 16S rRNA high-throughput sequencing to characterize the microbiota of the nasal cavity in 163 children and adolescents clustered into different asthma phenotypes. RESULTS: Our clustering analyses identified three statistically distinct phenotypes of pediatric asthma. Four core OTUs of the pathogenic genera Moraxella, Staphylococcus, Streptococcus, and Haemophilus were present in at least 95% of the studied nasal microbiotas. Phyla (Proteobacteria, Actinobacteria, and Bacteroidetes) and genera (Moraxella, Corynebacterium, Dolosigranulum, and Prevotella) abundances, community composition, and structure varied significantly (0.05 < P <= 0.0001) across asthma phenotypes and one of the clinical variables (preterm birth). Similarly, microbial networks of co occurrence of bacterial genera revealed different bacterial associations across asthma phenotypes. CONCLUSIONS: This study shows that children and adolescents with different clinical characteristics of asthma also show different nasal bacterial profiles, which is indicative of different phenotypes of the disease. Our work also shows how clinical and microbial information could be integrated to validate and refine asthma classification systems and develop biomarkers of disease. PMID- 30286810 TI - Identification of gross deletions in FBN1 gene by MLPA. AB - BACKGROUND: Marfan syndrome (MFS) is an autosomal dominant connective tissue disorder caused by mutations in the FBN1 gene. Approximately 90% of classic MFS patients have a FBN1 mutation that can be identified by single-gene sequencing or gene-panel sequencing targeting FBN1. However, a small proportion of MFS patients carry a large genomic deletion in FBN1, which cannot be detected by routine sequencing. Here, we performed an MLPA (multiplex ligation-dependent probe amplification) test to detect large deletions and/or duplications in FBN1 and TGFBR2 in 115 unrelated Chinese patients with suspected MFS or early-onset aneurysm/dissection. RESULTS: Five novel large deletions encompassing a single exon or multiple exons in the FBN1 gene were characterized in five unrelated patients, of which four were proven by Sanger sequencing, and the breakpoints were identified. Three of them met the revised Ghent criteria when genetic results were not available, and the other two patients were highly suspected and diagnosed with MFS until the FBN1 deletions were identified. CONCLUSIONS: Our finding expands the mutation spectrum of large FBN1 deletions and emphasizes the importance of screening for large FBN1 deletions in clinical genetic testing, especially for those with classic Marfan phenotype. PMID- 30286809 TI - Therapeutic and immunoregulatory effects of water-soluble alkaloids E2-a from Sophora moorcroftiana seeds as a novel potential agent against echinococcosis in experimentally protoscolex-infected mice. AB - Novel compounds and more efficient treatment options are urgently needed for the treatment of cystic echinococcosis (CE), which is caused by Echinococcus granulosus. The decoction of Sophora moorcroftiana (Fabaceae) has been used to treat parasitosis for years in traditional Tibetan medicine. The aim of this study was to screen insecticidal water-soluble alkaloids from S. moorcroftiana seeds and evaluate the therapeutic effects against CE and the immune response induced by the alkaloidal fraction. Low polarity compounds (E2-a) were isolated from water-soluble alkaloid (E2) and matrine and sophocarpine were identified as major components. The E2-a fraction was more effective against protoscoleces than other constituents from S. moorcroftiana. After 20 weeks of secondary infection with protoscoleces, mice were orally treated with E2-a (100 mg/kg/day) for 6 weeks to evaluate therapeutic and immunoregulatory activities. Compared with the untreated group, E2-a treatment induced a significant reduction in cyst weight (mean 2.93 g) (p < 0.05) and an impaired ultrastructural modification of the cyst. Interestingly, the application of E2-a resulted in a significant increased frequency of CD3+CD4+ T-cell subsets and decreased frequency of CD3+PD-1+ T-cell subsets, compared with protoscolece-infected mice without treatment. The E2-a fraction of S. moorcroftiana can inhibit the cyst development of CE and boost the specific immune response by reducing the expression of PD-1 and accelerate the cytokine secretion of antigen-specific T-cells. All data suggest the E2-a fraction from S. moorcroftiana seeds may be used as a new potential therapeutic option against E. granulosus infection. PMID- 30286812 TI - The role of saline irrigation prior to wound closure in the reduction of surgical site infection: protocol for a systematic review and meta-analysis. AB - BACKGROUND: Surgical site infection describes an infectious complication of surgical wounds. This single complication is thought to occur in close to 20% of surgical cases. This complication has been described in all kinds of surgical procedure including minimally invasive procedures. Wound irrigation is frequently used as a means of reducing surgical site infection. However, there is lack of solid evidence to support routine wound irrigation. The aim of this review is to provide evidence for the efficacy of routine wound irrigation with normal saline in preventing surgical site infection. The rate of surgical site infection in cases with and without wound irrigation will be analyzed. METHODS/DESIGN: Systematic literature searches will be conducted to identify all published and unpublished studies. The following databases will be searched for citations from inception to present: MEDLINE (via PubMed), Embase (via Embase), and CENTRAL (via the Cochrane library). The search strategy will be developed by the research team in collaboration with an experienced librarian and checked by a referee according to the Peer Review of Electronic Search Strategies (PRESS) guideline. A draft of the PubMed search strategy could be (irrigation[tiab] OR "Therapeutic Irrigation"[mesh] OR lavage[tiab]) AND (saline[tiab] OR "Sodium Chloride"[mesh] OR sodium chloride[tiab]) NOT ("Comment" [Publication Type] OR "Letter" [Publication Type] OR "Editorial" [Publication Type]). No time limits will be set. The reference lists of eligible articles will be hand searched. Relevant data will be extracted from eligible studies using a previously designed data extraction sheet. Relative risks will be calculated for binary outcomes and mean differences or standardized mean differences, if necessary, for continuous outcomes. For all measures, 95% confidence levels will be calculated. Both arms would be compared with regard to the rate of surgical site infection within 30 days following surgery. We will report the review using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. DISCUSSION: This review aims at investigating the value of routine wound irrigation using normal saline in preventing surgical site infection. SYSTEMATIC REVIEW REGISTRATION: PROSPERO: CRD42018082287. PMID- 30286814 TI - Time-varying associations of racial discrimination and adjustment among Chinese heritage adolescents in the United States and Canada. AB - The aim of our study was twofold: to examine (a) whether the link between racial discrimination and adjustment showed age-related changes across early to late adolescence for Chinese-heritage youth and (b) whether the age-related associations of the discrimination-adjustment link differed by gender, nativity, and geographical region. We pooled two independently collected longitudinal data sets in the United States and Canada (N = 498, ages 12-19 at Wave 1) and used time-varying effect modeling to show that discrimination is consistently associated with poorer adjustment across all ages. These associations were stronger at certain ages, but for males and females, first- and second-generation adolescents, and US and Canadian adolescents they differed. There were stronger relations between discrimination and adjustment in early adolescence for males compared to females, in middle adolescence for first-generation compared to second-generation adolescents, and in early adolescence for US adolescents compared to Canadian adolescents. In general, negative implications for adjustment associated with discrimination diminished across the span of adolescence for females, second-generation, and US and Canadian adolescents, but not for males or first-generation adolescents. The results show that the discrimination-adjustment link must be considered with regard to age, gender, nativity, and region, and that attention to discrimination in early adolescence may be especially important. PMID- 30286815 TI - Field Evaluation of a Novel UV Water Disinfection System for use in Underserved Rural Communities. AB - Reliable, robust, and inexpensive disinfection systems are needed to expand water security in remote and underserviced areas. This paper reports on the deployment and evaluation of a novel UV water-disinfection system in a remote rural community. Prior laboratory tests indicated a 7.12 log10 reduction of the bacteriophage MS-2 at a flow rate of 9.46 liter/min, which corresponds to a supplied UV dose 215 mJ/cm2. Further tests in water containing turbidity levels up to 18 NTU showed E. coli removal remaining above the 5 log10 level. Field testing was performed at a Native American reservation in Northern California where the system was used to treat groundwater obtained from a well with a known fecal contamination. The system was powered by solar panel and was operated on demand for extended periods. Tests on the treated water showed that the system exceeded the standard of disinfection required for drinking water. PMID- 30286813 TI - Inhibition of Salmonella Typhimurium adhesion, invasion, and intracellular survival via treatment with methyl gallate alone and in combination with marbofloxacin. AB - Salmonella enterica serovar Typhimurium infects intestinal epithelia and macrophages, which is prevented by inhibiting adhesion and cell invasion. This study aimed to investigate the role of methyl gallate (MG) in adhesion, invasion, and intracellular survival of Salmonella Typhimurium in Caco-2 and RAW 264.7 cells via a gentamicin protection assay, confocal microscopy, and quantitative reverse-transcription polymerase chain reaction. MG (30 ug/mL) inhibited adhesion and invasion of Salmonella Typhimurium by 54.01% and 60.5% in RAW 264.7 cells, respectively. The combination of MG with sub-minimum inhibitory concentration (MIC) of marbofloxacin (MRB) inhibited the adhesion, invasion, and intracellular survival by 70.49%, 67.36%, and 74%, respectively. Confocal microscopy further revealed reductions in bacterial count in Caco-2 cells treated with MG alone or with sub-MIC of MRB. Furthermore, MG alone or in combination with sub-MIC of MRB decreased the motility of Salmonella Typhimurium. Quorum sensing genes including sdiA, srgE, and rck were downregulated by 52.8%, 61.7%, and 22.2%, respectively. Moreover, rac-1 was downregulated by 56.9% and 71.9% for MG alone and combined with sub-MIC of MRB, respectively, in mammalian cells. Furthermore, MG downregulated virulence genes of Salmonella Typhimurium including cheY, ompD, sipB, lexA, and ompF by 59.6%, 60.2%, 20.5%, 31.4%, and 16.2%, respectively. Together, the present results indicate that MG alone or in combination with a sub MIC of MRB effectively inhibited the adhesion, invasion, and intracellular survival of Salmonella Typhimurium in vitro by downregulating quorum sensing and virulence genes. PMID- 30286811 TI - Chinese expert consensus on echelons treatment of thoracic injury in modern warfare. AB - The emergency treatment of thoracic injuries varies of general conditions and modern warfare. However, there are no unified battlefield treatment guidelines for thoracic injuries in the Chinese People's Liberation Army (PLA). An expert consensus has been reached based on the epidemiology of thoracic injuries and the concept of battlefield treatment combined with the existing levels of military medical care in modern warfare. Since there are no differences in the specialized treatment for thoracic injuries between general conditions and modern warfare, first aid, emergency treatment, and early treatment of thoracic injuries are introduced separately in three levels in this consensus. At Level I facilities, tension pneumothorax and open pneumothorax are recommended for initial assessment during the first aid stage. Re-evaluation and further treatment for hemothorax, flail chest, and pericardial tamponade are recommended at Level II facilities. At Level III facilities, simple surgical operations such as emergency thoracotomy and debridement surgery for open pneumothorax are recommended. The grading standard for evidence evaluation and recommendation was used to reach this expert consensus. PMID- 30286816 TI - A Missed Connection: Dietary Protein Intake and Mortality in Hemodialysis.

While early diagnosis and treatment of PEW can reduce mortality, clinically practical measures for its detection are lacking. Poor dietary protein intake (DPI) is associated with risk of malnutrition and PEW. However, the impact of DPI on mortality is unclear. The purpose of this study is to examine the ability of DPI to predict 1-year mortality in dialysis patients. METHODS: This prospective, secondary study using data from the Comprehensive Dialysis Study and United States Renal Data System examined risk factors associated with 1-year mortality in dialysis patients. RESULTS: Seventeen (7.5%) of the 227 subjects died within 1 year following baseline data collection. One year survivors were significantly younger (60 +/- 13.6 versus 71 +/- 12.8; P = 0.0043), had a lower Charlson Comorbidity Index score (1.6 +/- 2.3 versus 4.0 +/- 3.6; P = 0.0157), higher serum albumin level (3.5 +/- 0.5 versus 3.3 +/- 0.4; P = 0.0173) and had higher DPI (63 +/- 33.7 versus 49.5 +/- 21.5 g/day; P = 0.0386) than those who died. In multivariable Cox proportional hazards model analyses, only the Charlson Comorbidity Index adjusted hazard ratio for death (1.24) was significantly associated with increased mortality. The Comprehensive Dialysis Study data showed no association between DPI and 1-year mortality in dialysis patients. CONCLUSIONS: Future studies using more precise measures should further examine the impact of DPI on mortality given the known association of DPI with PEW syndrome and the definitive link between PEW syndrome and survival in dialysis patients. PMID- 30286819 TI - Cardiovascular Parameters Associated With Troponin I as Indicators for 14-Day Mortality in Patients With Septic Shock. AB - BACKGROUND: Troponin I is better than other troponin isoforms for monitoring cardiocyte damage, and correlates with sepsis-related mortality. However, hemodynamic factors possibly interact with cardiac function to affect mortality in sepsis. Thus, this study used parameters from pulse-induced contour cardiac output (PiCCO) to investigate the possibility. METHODS: Patients with troponin I tests and sequential organ failure assessment score >=2 were selected and divided into survivors and nonsurvivors groups and blood troponin I levels between them were compared. Additionally, 65 patients with septic shock and PiCCO records were selected and divided into high cardiac function index (CFI) and low CFI groups and their cardiac function associated with troponin I levels was checked. Furthermore, the patients were classified into 4 subgroups based on CFI and another hemodynamical parameter of PiCCO for identifying if any interaction between CFI and the parameter existed. RESULTS: High blood troponin I levels correlated with high mortality, and with low cardiac function (CFI < 4.5) alone or with low CFI combined with high stroke volume variation (SVV), but did not correlate with global end-diastolic index (GEDI), or systemic vascular resistance index. However, only the subgroup with low CFI and high SVV (CFI < 4.5 and SVV > 10) increased mortality. CONCLUSIONS: Our data give an insight into interactions between cardiac and hemodynamic factors to cause cardiocyte damage and suggest that multiple factors (i.e., low CFI and high SVV) should be considered together to evaluate cardiocyte damage and mortality in sepsis. PMID- 30286820 TI - Efficacy and Safety of Policosanol Plus Fenofibrate Combination Therapy in Elderly Patients with Mixed Dyslipidemia: A Randomized, Controlled Clinical Study. AB - BACKGROUND: Policosanol is a mixture of long-chain alcohols isolated from sugar cane. This controlled, randomized clinical trial was designed to compare the efficacy and safety of fenofibrate, policosanol and a combination of these 2 in lowering low-density-lipoprotein cholesterol (LDL-C) in elderly patients with mixed dyslipidemia. METHODS: A total of 102 patients aged >=60years were randomly assigned into 3 groups: patients receiving a 24-week therapy of fenofibrate (200 mg/day), policosanol (20 mg/day) or fenofibrate + policosanol combination. Lipids were evaluated at baseline, after 16 and after 24 weeks of therapy. Brachial ankle pulse wave velocity (ba-PWV) was performed, and SF-36 questionnaires were used to evaluate the patients' quality of life. The primary endpoint was the percentage reduction in LDL-C. The secondary end points included percentage change in nonhigh density lipoprotein cholesterol (non-HDL-C), total cholesterol (TC), triglyceride, high-density-lipoprotein cholesterol (HDL-C), ba-PWV and SF 36 scores. Safety was assessed by adverse events and laboratory parameters. RESULTS: LDL-C, non-HDL-C and TC were decreased, respectively after treatment with policosanol for 24 weeks (P < 0.01). Treatment with policosanol + fenofibrate resulted in significantly greater reductions in TC, non-HDL-C and LDL C compared to fenofibrate alone (P < 0.01, respectively). There were significant increases in SF-36 scores in the policosanol and policosanol + fenofibrate groups (P < 0.05), and significant improvements of ba-PWV in the 2 groups (P < 0.01). There were no serious adverse events or significant changes in laboratory variables after any of the treatment regimens. CONCLUSIONS: Policosanol + fenofibrate combination therapy significantly improved lipid parameters, arterial stiffness, and quality of life, with good tolerability. PMID- 30286821 TI - Timing of Left Ventricular Remodeling in Nonischemic Dilated Cardiomyopathy. AB - BACKGROUND: Mineralocorticoid receptor antagonist (MRA) treatment produces beneficial left ventricular (LV) remodeling in nonischemic dilated cardiomyopathy (NIDCM). This study addressed the timing of maximal beneficial LV remodeling in NIDCM when adding MRA. MATERIALS AND METHODS: We studied 12 patients with NIDCM on stable beta-blocker and angiotensin-converting enzyme inhibitor/angiotensin receptor-blocking therapy who underwent cardiac magnetic resonance imaging before and after 6-31 months of continuous MRA therapy. RESULTS: At baseline, the LV ejection fraction (LVEF) was 24% (19-27); median [interquartile range]. The LV end-systolic volume index (LVESVI) was 63 ml (57-76) and the LV stroke volume index (LVSVI) was 19 ml (14-21), all depressed. After adding MRA to the HF regimen, the LVEF increased to 47% (42-52), with a decrease in LVESVI to 36 ml (33-45) and increase in LVSVI to 36 ml (28-39) (for each, P < 0 .0001). Using generalized least squares analysis, the maximal beneficial remodeling (defined by maximal increase in LVEF, the maximal decrease in LVESVI and maximal increase in LVSVI) was achieved after approximately 12-16 months of MRA treatment. CONCLUSIONS: Adding MRA to a standard medical regimen for NIDCM resulted in beneficial LV remodeling. The maximal beneficial remodeling was achieved with 12 16 months of MRA therapy. These results have implications for the timing of other advanced therapies, such as placing internal cardioverter-defibrillators. PMID- 30286822 TI - Hematuria and Renal Outcomes in Patients With Diabetic Chronic KidneyDisease. AB - BACKGROUND: Hematuria may indicate nondiabetic renal disease in diabetic chronic kidney disease (CKD). However, some studies have reported that hematuria is noted in diabetic nephropathy and is associated with albuminuria. Hematuria is a risk factor for end-stage renal disease in glomerulonephritis, but its prognostic value in diabetic CKD is unknown. We investigated the factors associated with hematuria and the prognostic value of hematuria in patients with diabetic CKD. MATERIAL AND METHODS: We included 1958 patients with type 2 diabetes and CKD stages 1-5, and 111 patients underwent renal biopsy. Patients in the biopsied cohort were younger and had more severe proteinuria, compared with those in the total cohort; hematuria was associated with nondiabetic renal disease. RESULTS: In the total cohort, hematuria was observed in 15.0% of the patients and was associated with young age, a lower estimated glomerular filtration rate, proteinuria, high blood pressure and short diabetes duration. Hematuria was significantly associated with an increased risk (hazard ratio 1.39, 95% CI: 1.10 1.76, P < 0.001) of end-stage renal disease, particularly in patients with CKD stages 1-3 or a urine protein-to-creatinine ratio of <1,500mg/g (P for interaction < 0.05). The odds ratio of hematuria for rapid renal progression was 1.81 (95% CI: 1.29-2.53, P < 0.001). CONCLUSIONS: Hematuria is associated with nondiabetic renal disease in biopsied patients with diabetic CKD and is associated with an increased risk of end-stage renal disease in patients with early diabetic CKD. PMID- 30286823 TI - Sepsis: An Update on Current Practices in Diagnosis and Management. AB - Despite several advancements in care over the last few decades, sepsis continues to carry a high morbidity and mortality burden in the United States. With its varied presentations, cases of sepsis are likely to be encountered by general practitioners in both inpatient and outpatient settings. In the recent years, there has been much debate about the appropriate criteria to diagnose patients with sepsis with a concurrent change in management guidelines. This article reviews definitions, diagnosis and treatment guidelines in current practice in the management of patients with sepsis. PMID- 30286824 TI - Complications of Cirrhosis in Primary Care: Recognition and Management of Hepatic Encephalopathy. AB - Approximately 3.7% of patients in primary care settings have chronic liver disease, and 18% with chronic liver disease in the specialty care setting have cirrhosis. For cirrhotic patients without complications, prognosis is generally favorable; increased morbidity and mortality are observed when complications (i.e., hepatic encephalopathy [HE]) occur. HE occurs in up to 70% of patients with cirrhosis. Neurologic signs in HE span a wide spectrum, from those not easily apparent (covert) to more clinically obvious signs (overt). Providers should consider overt HE in patients with cirrhosis and signs of impaired cognition, confusion, consciousness and/or personality changes, and/or impaired memory. Overt HE treatment includes identifying and treating precipitating factors and reducing bacterial-derived toxin loads. For acute overt HE, lactulose is first-line treatment. To prevent HE recurrence, lactulose plus rifaximin is recommended. Patients with cirrhosis and HE often present in primary care; recognizing and properly managing HE are important in this setting.

PMID- 30286829 TI - Diagnostic Utility of Complement Serology for Atypical Hemolytic Uremic Syndrome. AB - OBJECTIVE: To investigate the clinical utility of a 9-analyte complement serology panel (COMS) covering complement function (CH50 and AH50), components (C3, C4), factor B (CFB), factor H, and activation markers (C4d, Bb, and soluble membrane attack complex) for the diagnosis of atypical hemolytic uremic syndrome (aHUS). METHODS: Physician orders for COMS from January 19, 2015, through November 4, 2016, were reviewed. Demographic characteristics, patient diagnosis, and laboratory parameters were recorded. RESULTS: There were 177 COMS orders for 147 patients. The median patient age was 44.9 years (range, 0.9-88.0 years). Common reasons for ordering COMS included monitoring and diagnosis of C3 glomerulopathy and renal dysfunction and differentiation of aHUS from other thrombotic microangiopathies (TMAs). Forty-four patients had COMS ordered for TMAs: 8 had aHUS and all had 1 or more abnormalities within the alternative pathway of complement. Although the sensitivity of this finding for the diagnosis of aHUS is 100%, the specificity is only 28%, with a positive likelihood ratio of 1.39. Patients with aHUS had lower CH50, C3, and CFB than did those with secondary non aHUS TMA (all P<.01). A combined CFB of 20.9 mg/dL or less and CH50 of 56% or less led to sensitivity of 75% with increased specificity of 88.9% and a diagnostic odds ratio of 24. CONCLUSION: A COMS abnormality should not be interpreted in isolation. In conjunction with clinical presentation, a decrease in both CFB and CH50 may be an important clue to support the diagnosis of aHUS. PMID- 30286830 TI - Food Allergy: A Comprehensive Population-Based Cohort Study. AB - OBJECTIVE: To determine the incidence and temporal trends of food allergies. PATIENTS AND METHODS: We performed a historical cohort study to describe the epidemiology of food allergies among residents of all ages in Olmsted County, Minnesota, during a 10-year period from January 2, 2002, through December 31, 2011, using the Rochester Epidemiology Project database. Overall incidence and trends in biannual incidence rates over time were evaluated. RESULTS: During the 10-year study period, 578 new cases of food allergies were diagnosed. The average annual incidence rate was significantly higher among males compared with females (4.1 [95% CI, 3.6-4.5] vs 3.0 [95% CI, 2.7-3.4]; P<.001; per 10,000 person-years; 3.6 per 10,000 person-years overall). The pediatric incidence rate of food allergy increased from 7.0 (95% CI, 6.2-8.9) to 13.3 (95% CI, 10.9-15.7) per 10,000 person-years between the 2002-2003 and 2006-2007 calendar periods and then stabilized at 12.5 and 12.1 per 10,000 person-years in the last 2 calendar periods. Milk, peanut, and seafood were the most common allergen in infancy, in children between ages 1 and 4 years, and in the adult population, respectively. CONCLUSION: This is one of the first population-based studies to examine the temporal trends of food allergies. The incidence of food allergies increased markedly between 2002 and 2009, with stabilization afterward. Additional longitudinal studies are warranted to assess for epidemiological evidence of changes in food allergy incidence with changing recommendations for allergenic food introduction. PMID- 30286831 TI - Outcomes of Percutaneous Coronary Interventions in Patients With Anemia Presenting With Acute Coronary Syndrome. AB - OBJECTIVE: To study the influence of anemia on long-term outcomes of patients with acute coronary syndrome undergoing percutaneous coronary intervention (PCI). PATIENTS AND METHODS: The study included 5668 consecutive unique patients with acute coronary syndrome who underwent PCI at Mayo Clinic from January 1, 2004, through December 31, 2014. The patients were stratified on the basis of the presence (hemoglobin [Hgb] level, <13 g/dL in men and <12 g/dL in women) and severity (moderate to severe Hgb level, <11 g/dL in men and women) of pre-PCI anemia and compared with patients without anemia. The primary outcomes were in hospital and long-term all-cause mortality after balancing baseline comorbidities using the inverse propensity weighting method. RESULTS: Unadjusted all-cause in hospital mortality (4.6% [84 of 1831] vs 2.0% [75 of 3837]) and 5-year follow-up mortality (44.4% [509] vs 15.4% [323]) were higher in patients with anemia than in those without anemia (P<.001 for both). After applying inverse propensity weighting analysis, the all-cause in-hospital mortality (2.0% [37] vs 2.0% [75]; P=.85) and 5-year mortality (17.8% [203] vs 15.4% [323]; P=.05) were not significantly different between patients with and without anemia; however, there were higher rates of all-cause 5-year mortality in patients with moderate to severe anemia (22.3% [113] vs 15.4% [323]; P<.001) compared with patients without anemia. The trend in 5-year mortality was driven by increased noncardiac mortality in patients with anemia (10.2% [91] vs 7.1% [148]; P=.04) and moderate to severe anemia (10.4% [52] vs 7.1% [148]; P=.006) when compared with nonanemic patients. CONCLUSION: After accounting for differences in risk profiles of anemic and nonanemic patients, anemia appeared to be an independent risk factor for increased long-term all-cause and noncardiac mortality. PMID- 30286832 TI - Association of Statin Use With Mortality After Dialysis-Requiring Acute Kidney Injury: A Population-Based Cohort Study. AB - OBJECTIVE: To investigate the association between statin use and mortality in patients with dialysis-requiring acute kidney injury (AKI-D). PATIENTS AND METHODS: This nationwide, population-based, retrospective cohort study included 6091 hospitalized patients with AKI-D (1271 statin users and 4820 statin nonusers) retrieved from the National Health Insurance Research Database of Taiwan between January 1, 2000, and December 31, 2012. All the patients were followed up until December 31, 2013. Primary and secondary outcomes were 1-year and in-hospital mortality, respectively. All the primary analyses were performed using the intention-to-treat approach. RESULTS: During 1-year follow-up, 492 of 1271 statin users (38.7%) and 2365 of 4820 statin nonusers (49.1%) died. After propensity score matching, statin use was independently associated with lower risks of 1-year all-cause mortality (hazard ratio [HR], 0.79; 95% CI, 0.69-0.9; P<.001) and in-hospital all-cause mortality (HR, 0.84; 95% CI, 0.71-0.99; P=.04). The survival benefit of statin treatment was dose-dependent and consistent across subgroups based on sensitivity analyses. CONCLUSION: Statin use was independently associated with reduced risks of 1-year and in-hospital mortality in patients with AKI-D. Statin therapy may be beneficial in this patient group. However, further clinical trials should be performed to confirm the findings. PMID- 30286833 TI - COPD Guidelines: A Review of the 2018 GOLD Report. AB - Global Strategy for the Diagnosis, Management, and Prevention of COPD 2018 is a consensus report published periodically since 2001 by an international panel of health professionals from respiratory medicine, socioeconomics, public health, and education comprising the Global Initiative for Chronic Obstructive Lung Disease (GOLD). The GOLD documents endeavor to incorporate latest evidence and expert consensus and are intended for use as "strategy documents" for implementation of effective care for chronic obstructive lung disease (COPD) on a global level. The GOLD 2018 report defines COPD as a "common, preventable and treatable disease that is characterized by persistent respiratory symptoms and airflow limitation that is due to airway and/or alveolar abnormalities, usually caused by significant exposure to noxious particles or gases," with the criteria of "persistent respiratory symptoms" being a new and controversial inclusion since 2017. With the availability of newer pharmacotherapy options, treatment recommendations are made on the basis of a review of the latest literature and directed by symptom burden and health care utilization. Apart from the change in definition, a major shift in the recommendations is the exclusion of severity of airflow limitation as one of the major factors in guiding therapy. We review the salient features of the GOLD 2018 document and provide commentary on features that merit further discussion based on our clinical experience and practice as well as literature review current as of February 2018. PMID- 30286834 TI - Influence of Renal Function on the Pharmacokinetics, Pharmacodynamics, Efficacy, and Safety of Non-Vitamin K Antagonist Oral Anticoagulants. AB - With the growing integration of non-vitamin K antagonist oral anticoagulants (NOACs) into clinical practice, questions have arisen regarding their use in special populations, including groups that may have been underrepresented in clinical trials. Patients with renal impairment, particularly in the lower echelons of renal function, are one such group. In an effort to elucidate the current evidence regarding the use of NOACs in patients with renal impairment, a systematic assessment of the literature was performed. The MEDLINE database was interrogated for studies and analyses evaluating the influence of renal function on the pharmacokinetics, pharmacodynamics, efficacy, and safety of NOACs published from January 1, 2000, through August 2, 2017. The 82 relevant publications retrieved highlight the diversity in the NOAC class regarding the impact of renal function on drug clearance, drug exposures, and clinical trial outcomes. In several large clinical trials, subgroup analyses revealed no significant differences when patients were stratified by creatinine clearance as a measure of renal function. Efficacy findings, in particular, were largely aligned with the overall population in the included studies. However, relative risks of bleeding were shown to vary, sometimes driven by changes in bleeding event rates in the comparator arm (eg, warfarin, enoxaparin). With few exceptions, minimal influence of mild renal impairment was observed on the relative efficacy and safety of NOACs. Taken together, the evidence suggests that the presence of renal impairment merits careful consideration of anticoagulant choice but should not deter physicians from appropriate use of NOACs.

AB - OBJECTIVE: To evaluate patterns of association between anxiety and depression and the different elements of the construct of quality of life, in patients with locally advanced breast cancer or disseminated stages METHODS: With a single measure over time, HADS and FACIT-B scales were applied in 107 women histologically confirmed to have breast cancer, in stages IIB, IIIA, IIIB, IIIC and IV. Factor analysis and multidimensional scaling methods were used to analyze patterns of association RESULTS: In 84.1% of the patients clinical anxiety was found (95%CI, 75.8-90.5%) and clinical depression in 25.2% (95%CI, 17.3-34.6%). Factor analysis groups items of the two scales in 4 domains which accounted for 59% of the total variance, where 2 items (H11 and B8) showed high values of uniqueness and low factor loadings. Multidimensional scaling suggests five groups, showing proximity between depressive symptoms and physical symptoms, as well as between anxious symptoms and related to functionality and social and family environment CONCLUSIONS: The HADS in patients with neoplastic disease detects a high frequency of depressive and especially anxious symptoms, which makes it advisable to reevaluate their psychometric properties in patients with cancer. The association between depressive symptoms of HADS and physical symptoms of quality of life construct is in favor of the difficulty of diagnosing depressive disorder in patients with cancer, so it may be necessary to develop instruments that allow locating symptoms or clinical characteristics that facilitate this diagnosis. PMID- 30286842 TI - Relationship Between Cognitive Function and Clinical Features in Patients With Bipolar I Disorder. AB - INTRODUCTION: Previous studies suggest that the severity of alterations in cognitive functions in people with a diagnosis of bipolar I disorder (BP-I) are directly related to the deterioration in overall functioning and life quality. Altered cognitive function is associated with a worse prognosis of BP-I, however little is known about the relationship between cognitive functions and the clinical features of BP-I. OBJECTIVE: To establish possible associations between cognitive function and the clinical and socio-demographic characteristics of patients with BP-I. METHODS: Cognitive function was evaluated by applying a neuropsychological battery to a group of patients with a BP-I diagnosis, who did not have affective episodes for at least 6 months, and who were outpatients treated at the San Juan de Dios Clinic in Manizales. The statistical analysis involved using clustering methocology in order to divide those patients with the best and worst cognitive function and it was later correlated with the clinical and socio-demographic variables. RESULTS: A statistically significant corrrelation was found between the number of years of education and the age the disorder started with alterations in the level of cognitive function (P=.002 and P=.017 respectively). No significant correlations were found with other variables. CONCLUSIONS: An early onset of the pathology and fewer years of education seems to be risk factors associated with poorer cognitive function in patients with BP-I. PMID- 30286844 TI - The Psychopathology of Delusion of Control According to Subjective Experience. AB - BACKGROUND: Delusion of control, including thought insertion, occurs in 20% of patients with schizophrenia. However little is known of its psychopathology, and studies involving patients are scarce. AIMS: To explore the subjective experience of patients with delusion of control and to propose a psychopathological explanation based on empirical evidence. METHODS: Qualitative exploratory study of 7 patients (6 with schizophrenia and 1 with schizophreniform disorder). A phenomenologically-oriented semi-structured interview was used. RESULTS: Delusion of control is not an isolated and pure symptom; it is always immersed in the context of a persecutory delusion and other psychiatric symptoms. The patient experiences partial control, i.e. the control is never complete. In all cases, it is possible to trace the history of the narrative formation of delusion of control from its origins in persecutory delusions and other concomitant symptoms. CONCLUSIONS: The delusion of control is a narrative resulting from the joint presence of a persecutory delusion and other psychiatric symptoms. For the patient, the delusion of control is the narrative of the elaborate expression of the meaning of the anomalous experience. Delusion of control is a narrative variety of persecutory delusion. PMID- 30286845 TI - Anxiety, Self-esteem and Body Image in Girls with Precocious Puberty. AB - Currently, the age of onset for pubertal changes is decreasing, especially in girls, which may have an impact on psychosocial factors such as anxiety, self esteem and body image. The aim of the present study is to compare these variables in two groups: a group of 15 girls with precocious puberty and a group of 16 girls of the same age without precocious puberty. A non-experimental descriptive design was used and the State-Trait Anxiety Inventory for Children (STAIC) and Self-Description Questionnaire (SDQ) were used to measure variables. Significant differences were found in Anxiety and Body Image levels between groups, but there were no differences in Self-Esteem levels. In conclusion, the findings show girls with early onset pubertal changes present high anxiety levels and negative body image compared to girls who start pubertal changes at the normal time. PMID- 30286846 TI - Validity and Reliability of the Spanish Version of the Montreal Cognitive Assessment (MoCA) for the Detection of Cognitive Impairment in Mexico. AB - OBJECTIVE: To establish the validity and reliability of the Montreal Cognitive Assessment in Spanish (MoCA-S) to identify mild cognitive impairment (MCI) and dementia in the Mexican elderly population. MATERIAL AND METHODS: 168 participants from a memory clinic in Mexico City were enrolled and divided into 3 groups: 59 cognitively healthy (CHG), 52 with mild cognitive impairment (MCI) (DSM-5 criteria) and 57 with dementia (NINCDS-ADRDA criteria). The MoCA-S and Mini-Mental State Evaluation (MMSE) were applied at baseline and during the last months to establish intra-observer reliability. ROC curves and a multinomial regression model were constructed to evaluate the effect of age and education on MoCA-S performance. RESULTS: The mean age of the participants was 76+/-8.1 years and the education rate was 10.7+/-5.2. The MoCA-S scores by group were: CHG, 27.3+/-1.9; MCI, 22.9+/-2.9; and dementia, 13.7+/-4.9 (p<0.001). The reliability of the MoCA-S was 0.89 and the intraclass correlation coefficient was 0.955. Sensitivity was 80% and specificity was 75%, with a cut-off point of 26 points for MCI (area under the curve, 0.886; p<0.001). For the dementia group, the sensitivity was 98% and specificity was 93%, with a cut-off point of 24points (area under the curve, 0.998; p<0.001). The multinomial regression showed no association with education and age for both the MCI and dementia groups. CONCLUSIONS: The MoCA-S is a valid and reliable instrument for MCI and dementia screening in the Mexican population, even after adjusting for age and education. PMID- 30286848 TI - Psycho-Social Evaluation of a Living Kidney Donor. AB - The decision to become a living kidney donor is full of conflicts. It is generally believed that the candidates are aware of their reasons, that they have thought long about it, and have even asked questions about it. Thus it is surprising that, in many cases, they are only vaguely aware of their reasons and their validity. Sometimes, it is an impulsive decision guided by their emotions and entrusted to their luck or faith. Sometimes, they are undecided and put under pressure due to various circumstances. The mental health assessment should help to clarify their reasons, and to put them into words. It should be a positive experience, enriching their decision. It should give the candidate the inner feeling of having received help for taking the best decision. The psychosocial evaluation should be the first of multiple assessment ratings that the living kidney donor must face. A well-taken decision is a requirement to start the process properly. The author reviews the conditions in which that interview should be developed, the requirements to be met by the decision, and the proper techniques to obtain accurate information. PMID- 30286847 TI - Psychiatric Disorders Secondary to Neurometabolic Disorders. AB - Some diseases secondary to inborn errors of metabolism are associated with psychiatric disorders or minor neurological symptoms. The existence of some cases with exclusively psychiatric symptoms represents a diagnostic and therapeutic challenge. The aim of this article is to describe seven treatable neurometabolic disorders that should be taken into account in the psychiatric consultation as they manifest with psychiatric symptoms that mask the organic origin of the disorder. Homocysteine metabolism and urea cycle disorders, Wilson's disease, Niemann-Pick disease Type C, acute porphyria and cerebrotendinous xanthomatosis are described. Following an analysis of the literature, a list of psychiatric symptoms associated with these disorders are proposed, ranging from insidious changes in affective state and thought to atypical symptoms such as visual hallucinations, as well as paradoxical effects of antipsychotics or behavioural disorders in children and adolescents associated with loss of autonomy. The most frequently associated neurological signs, such as alterations in the state of consciousness, motor behaviour and balance disorders, catatonia or progressive cognitive deficit are also listed. Emphasis is placed on the importance of considering resistance to antipsychotic treatment as a warning sign to suspect organicity, as well as the significant improvement in psychiatric impairment when effective and early treatment is established. PMID- 30286849 TI - Factors Associated With Quality of Online Information on Trapeziometacarpal Arthritis. AB - PURPOSE: People increasingly search the Internet for information about common medical problems such as trapeziometacarpal (TMC) joint arthritis. But this information can be biased, inaccurate, and misleading. Medical professionals should be aware of what patients may be reading about their condition because concepts and beliefs can affect symptoms, limitations, and decision making. This study sought factors associated with the quality of design and content of health information Web sites about TMC arthritis. METHODS: Using 3 search engines we entered "thumb arthritis" and measured the quality of design and content of 67 Web sites using the DISCERN and LIDA tools, dominant tones using the IBM Watson Tone Analyzer, and readability, and we recorded Web site characteristics. All but 1 Web site exceeded the recommended sixth-grade reading level. We created 2 backward stepwise regression models to identify independent factors associated with Web site design and content quality. RESULTS: In multivariable analysis, the Web site not having a clear preference for treatment was independently associated with greater design and content quality measured by DISCERN.

PMID- 30286850 TI - Finger Replantation Optimization Study (FRONT): Update on National Trends. AB - PURPOSE: Traumatic digit amputations have an adverse impact on patients' daily living. Despite experts advocating for digit replantation, studies have shown a continued decrease in rate of replantation. We performed a national-level investigation to examine the recent trend of practice for digital replantation. METHODS: We used the National Inpatient Sample database under the Healthcare Cost and Utilization Project to select adult patients with traumatic digit amputation from 2001 to 2014. We calculated the rate of attempted and rate of successful digit replantation per year, subcategorizing for digit type (thumb or finger) and for hospital type (rural, urban nonteaching, or urban teaching). We also analyzed the pattern of distribution of case volume to each hospital type per year. We used 2 multivariable logistic regression models to investigate patient demographic and hospital characteristics associated with the odds of replantation attempt and success. RESULTS: Among the 14,872 adult patients with a single digit amputation from 2001 to 2014, only 1,670 (11.2%) underwent replantation. The rate of replantation attempt trended down over the years for both thumb and finger injuries at all hospital types, despite increasing proportions of cases being sent to urban teaching hospitals where they were more than twice as likely to undergo replantation. The rate of successful replantation stayed stable for the thumb at 82.9% and increased for fingers from 76.1% to 82.4% over the years. Patients were more likely to undergo replantation if they had private insurance or a higher level of income. Neither hospital case volume nor hospital type was predictive of successful replantation. CONCLUSIONS: Although more single-digit amputations were treated by urban teaching hospitals with higher likelihood to replant, the downward trend in rate of attempt regardless of hospital type demonstrates that concentration of case volume is not the solution to reverse the declining trend. CLINICAL RELEVANCE: Financial aspects of digit replantation need to be considered from both the patients' and the surgeons' perspectives to improve delivery of care for digit replantation. PMID- 30286851 TI - Pain Management After Carpal Tunnel Release Surgery: A Prospective Randomized Double-Blinded Trial Comparing Acetaminophen, Ibuprofen, and Oxycodone. AB - PURPOSE: Adequate postoperative pain control in hand surgery is a multifactorial issue affecting patient satisfaction, outcomes, and safety. However, prescription opioid abuse is becoming an increasingly prevalent problem in the Unites States. The purpose of this study was to determine if there was a difference in pain levels or pill consumption when using nonopioids, ibuprofen (IBU) and acetaminophen (ACE), versus an opioid, oxycodone (OXY), after carpal tunnel release (CTR) performed exclusively under local anesthesia without sedation. METHODS: Patients scheduled for primary unilateral CTR under local anesthesia alone were randomized to receive 10 deidentified opaque capsules of either OXY 5 mg, IBU 600 mg, or ACE 500 mg after surgery. Both the patient and the surgeon were blinded to the distributed medication. Patients reported the worst pain experienced daily (0-10 scale), the number of pills consumed daily, and any adverse effects from postoperative days 0-5. RESULTS: Analgesic pill-type distribution between the 105 patients who completed the study was 37 OXY, 34 IBU, and 34 ACE. For the endoscopic CTR group, mean total pills consumed from the day of surgery through postoperative day 5 for OXY, IBU, and ACE were 2.9, 4.2, and 2.7, respectively. The average worst daily pain scores for all days for the OXY, IBU, and ACE groups were 2.8, 2.5, and 2.8, respectively. For the open CTR group, mean total pills consumed from the day of surgery through postoperative day 5 for OXY, IBU, and ACE were 3.7, 5.1, and 4.2, respectively. The average worst daily pain scores for all days for the OXY, IBU, and ACE groups were 3.4, 2.5, and 2.3, respectively. Four of 5 adverse events were reported by OXY group patients, but all were minor with no reoperations or readmissions. CONCLUSIONS: We recommend using nonopioids such as ACE and IBU in the postoperative management after CTR surgery, and regardless of the medication prescribed, we advise prescribing no more than 5-10 pills after surgery. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II. PMID- 30286852 TI - Double Motor Nerve Transfer for All Finger Flexion in Cervical Spinal Cord Injury: An Anatomical Study and a Clinical Report. AB - PURPOSE: To explore the feasibility of restoring all finger flexion after a cervical spinal cord injury. METHODS: Double nerve transfer was conducted in 22 cadaver upper extremities. Donor nerves were the brachialis branch of the musculocutaneous nerve and the extensor carpi radialis brevis (ECRB) branches of the radial nerve. Recipient nerves were the anterior interosseous nerve (AIN) and the flexor digitorum profundus (FDP) branch of ulnar nerve (ulnar-FDP). Nerve transfers were evaluated on 3 parameters: surgical feasibility, donor-to recipient axon count ratio, and distance from the coaptation site to the muscle entry of recipient nerve. A complete C6 spinal cord injury reconstruction was accomplished in a patient using a double nerve transfer of ECRB to ulnar-FDP and brachialis to AIN. RESULTS: In the cadaver study, nerve transfers from ECRB to AIN, brachialis to AIN, and ECRB to ulnar-FDP were all feasible. The transfer from the brachialis to ulnar-FDP was not possible. Mean myelinated axon counts of AIN, brachialis, ulnar-FDP, and ECRB were 2,903 +/- 1049, 1,497 +/- 606, 753 +/- 364, and 567 +/- 175, respectively. The donor-to-recipient axon count ratios of ECRB to AIN, brachialis to AIN, and ECRB to ulnar-FDP were 0.24 +/- 0.15, 0.55 +/ 0.38, and 0.98 +/- 0.60, respectively. The distance from coaptation of the ECRB to the ulnar-FDP muscle entry was shorter than for the other nerve transfers (54 +/- 14.29 mm). At 18 months, there was restoration of flexion in all fingers and functional improvement from double nerve transfer of the brachialis to the AIN and the ECRB to the ulnar-FDP. CONCLUSIONS: Restoration of all finger flexion may be feasible by the ECRB to ulnar-FDP and brachialis to AIN double nerve transfer. CLINICAL RELEVANCE: Double nerve transfer can be used in C6-C7 spinal cord injury and patients with lower arm-type brachial plexus injury who have no finger flexion but have good brachialis and ECRB.

PMID- 30286853 TI - 3-Year Outcomes of the Edwards SAPIEN Transcatheter Heart Valve for Conduit Failure in the Pulmonary Position From the COMPASSION Multicenter Clinical Trial. AB - OBJECTIVES: This study provides the 3-year follow-up results of the COMPASSION (Congenital Multicenter Trial of Pulmonic Valve Regurgitation Studying the SAPIEN Transcatheter Heart Valve) trial. Patients with moderate to severe pulmonary regurgitation and/or right ventricular outflow tract conduit obstruction were implanted with the SAPIEN transcatheter heart valve (THV). BACKGROUND: Early safety and efficacy of the Edwards SAPIEN THV in the pulmonary position have been established through a multicenter clinical trial. METHODS: Eligible patients were included if body weight was >35 kg and in situ conduit diameter was >=16 and <=24 mm. Adverse events were adjudicated by an independent clinical events committee. Three-year clinical and echocardiographic outcomes were evaluated in these patients. RESULTS: Fifty-seven of the 63 eligible patients were accounted for at the 3-year follow-up visit from a total of 69 implantations in 81 enrolled patients. THV implantation was indicated for pulmonary stenosis (7.6%), regurgitation (12.7%), or both (79.7%). Twenty-two patients (27.8%) underwent implantation of 26-mm valves, and 47 patients received 23-mm valves. Functional improvement in New York Heart Association functional class was observed in 93.5% of patients. Mean peak conduit gradient decreased from 37.5 +/- 25.4 to 17.8 +/- 12.4 mm Hg (p < 0.001), and mean right ventricular systolic pressure decreased from 59.6 +/- 17.7 to 42.9 +/- 13.4 mm Hg (p < 0.001). Pulmonary regurgitation was mild or less in 91.1% of patients. Freedom from all-cause mortality at 3 years was 98.4%. Freedom from reintervention was 93.7% and from endocarditis was 97.1% at 3 years. There were no observed stent fractures. CONCLUSIONS: Transcatheter pulmonary valve replacement using the Edwards SAPIEN THV demonstrates excellent valve function and clinical outcomes at 3-year follow-up.

PMID- 30286857 TI - WIRION Embolic Protection System in Lower Extremity Arterial Interventions: Results of the Pivotal WISE LE Trial. AB - OBJECTIVES: The WISE LE (WIRIONTM EPS in Lower Extremities Arteries) study was designed to assess the clinical performance of the WIRION Embolic Protection System (EPS) in subjects undergoing lower extremity atherectomy for the treatment of peripheral artery disease. BACKGROUND: Embolization is ubiquitous during endovascular procedures for lower extremity peripheral artery disease. METHODS: The WISE LE was a multicenter study, performed in the United States and Germany. The primary endpoint was freedom from major adverse events (MAEs) occurring within 30 days post-procedure and was compared with an objective performance goal derived from historical atherectomy trials. MAE was defined as a serious adverse event that resulted in death, acute myocardial infarction, thrombosis, pseudoaneurysm, dissection (grade C or greater), or clinical perforation at the filter location, clinically relevant distal embolism, unplanned amputation, or clinically driven target vessel revascularization. The study also included a histopathological analysis of debris captured by the filter during the procedures. RESULTS: The study protocol specified enrollment of 153 patients with the primary endpoint successfully met if 18 (12.0%) or fewer MAEs occurred. A pre specified interim analysis performed after 103 patients revealed only 2 MAEs, and the study was stopped because it had met its pre-determined metric for success. Lesion deemed not accessible by the WIRION EPS occurred in 7 patients. Debris of <1-mm, 1- to 2-mm, and >2-mm diameter were found in 98%, 22%, and 9% of patients, respectively. CONCLUSIONS: The WIRION EPS is safe and noninferior to the pre specified performance goal in capturing debris in the vast majority of patients and with the use of a broad range of atherectomy systems. PMID- 30286855 TI - 1-Year Clinical Outcomes of All-Comer Patients Treated With the Dual-Therapy COMBO Stent: Primary Results of the COMBO Collaboration. AB - OBJECTIVES: The aim of this study was to evaluate 1-year clinical safety and efficacy of the dual-therapy COMBO stent in a large, all-comers patient-level pooled cohort. BACKGROUND: The COMBO stent (OrbusNeich Medical, Fort Lauderdale, Florida) is a novel stent with abluminal sirolimus elution from a biodegradable polymer and a luminal pro-healing anti-CD34+ antibody layer, which attracts circulating endothelial progenitor cells. These endothelial progenitor cells can quickly mature into normal endothelium, providing rapid endothelialization. METHODS: The MASCOT (Multinational Abluminal Sirolimus Coated biO-engineered stenT) (N = 2,614, 61 global sites) and REMEDEE (Randomized study to Evaluate the safety and effectiveness of an abluMinal sirolimus coatED bio-Engineered StEnt Post Market Registry) (N = 1,000, 9 European sites) registries are 2 prospective, multicenter studies evaluating clinical outcomes after attempted COMBO stent placement in all-comer patients undergoing percutaneous coronary intervention. In this patient-level pooled analysis we analyzed 1-year target lesion failure (TLF), a composite of cardiac death, target vessel myocardial infarction, or clinically driven target lesion revascularization. Furthermore, we determined predictors of 1-year TLF. RESULTS: A total of 3,614 patients (63.5 +/- 11.2 years of age; 23.8% women) were included in this analysis. The prevalence of diabetes mellitus was 29.3%, and 54.3% patients presented with acute coronary syndrome. The primary endpoint of 1-year TLF occurred in 140 (3.9%) patients, with incidence of cardiac death in 1.6%, target vessel myocardial infarction in 1.2%, clinically driven target lesion revascularization in 2.2%, and definite stent thrombosis in 0.5% patients. Insulin-treated diabetes mellitus, chronic renal failure, and American College of Cardiology/American Heart Association lesion type B2/C were independent predictors of 1-year TLF. CONCLUSIONS: In this large patient-level pooled analysis of patients treated with the dual-therapy COMBO stent excellent results at 1-year were observed.

AB - OBJECTIVE: The aim of this study was to compare fertilisation, pregnancy rates and perinatal outcomes in patients undergoing intracytoplasmic sperm injection (ICSI) due to oligozoospermia. METHODS: A total of 166 patients with oligozoospermia who underwent an ICSI procedure were included in the study. The subjects were divided into two groups according to the sperm retrieval technique used: group 1, ejaculated semen (n=111); group 2, surgical sperm retrieval (n=55). RESULTS: Although the clinical pregnancy rate was lower in group 2, the difference was not statistically significant (36.4% vs. 42.3%, p=0.460). The difference between fertilisation and take-home baby rates of the groups were not significantly different, either (p=0.486, p=0.419, consecutively). CONCLUSION: Two different sperm retrieval techniques used for ICSI had no statistically significant difference on intracytoplasmic sperm injection outcomes in oligozoospermic patients. PMID- 30286867 TI - The relationship between inflammation and mean platelet volume in varicocele pathophysiology. AB - INTRODUCTION: The mean platelet volume (MPV) is an extensively employed laboratory indicator related to platelet volume and function in inflammatory circumstances. The aim of this study was to assess the relationship between inflammation and mean platelet volume in varicocele pathophysiology. METHODS: We conducted a recent study, which included 131 varicocele subjects and 82 healthy controls. The identification of varicocele was based on the results from both physical examination and color Doppler ultrasound. We analyzed some laboratory markers including haemogram tests in two groups. RESULTS: There were no significant differences in the two groups in terms of baseline characteristics. MPV values were statistically higher in the varicocele group (9.73+/-0.86fL) than in the control group (9.03+/-0.70fL) (p<0.001). However, no significant relationship between MPV and varicocele grade was found. Furthermore, the receiver-operating characteristic curve analysis suggested the optimum MPV cut off value for patients with varicocele as 9.05, with a sensitivity and specificity of 77% and 50%, respectively (p<0.001). CONCLUSION: MPV can offer information on varicocele pathophysiology. Increased MPV levels in varicocele patients may be associated with inflammation. PMID- 30286868 TI - Our urethrocutaneous fistula repair results in adults after hypospadias surgery. AB - INTRODUCTION: Our aim was to evaluate and share our urethrocutaneus fistula repair results in adult patients who had been operated for hypospadias in their childhood. MATERIAL AND METHODS: The data of totally 48 patients who had been treated for urethrocutaneous fistula after hypospadias surgery in our department from May 2008 to January 2015 analyzed retrospectively. Patients' age at fistula repair, age at first hypospadias surgery, fistula size, localization and number, distal urethral obstruction status and surgical outcomes of fistula repairs were recorded. All patients were controlled three months after the repair for surgical outcomes. RESULTS: Fistula repair performed in 45 patients. Mean age was 21.46 (20-26). Nineteen patients (42.2%) underwent first hypospadias surgery under the age of 7 years; 8 patients (17.7%) between 7 and 15 years, 18 patients between 15 and 20 years. Tubularized incised plate urethroplasty (TIPU) was performed in 40 patients (88.9%), extragenital tissue was used in 5 patients (11.1%). Twenty two patients (48.9%) had 1 or 2 operations, 17 patients (37.8%) had 3-5 operations and 6 patients (13.3%) had 6 or more operations. Thirteen (28.9%) coronal, 24 (53.3%) subcoronal, 6 (13.3%) penile and 2 (4.4%) penoscrotal fistulas were observed. While a single fistula was observed in 35 patients, multiple fistulas were seen in 10 patients. A fistula diameter les than 5mm was detected in 37 patients, and larger than 5mm in 8 patients. Fistula recurrence was observed in 3 patients at follow-up examinations carried out at 3 months postoperatively. The number of operations was more than 5, the fistula diameter was larger than 5mm and the fistulas were coronal in all three recurrent fistulas. CONCLUSION: According to our results fistula size, previous surgery and well-vascularised, one or two layer tissue were the important factors in the success of fistula repair after hypospadias surgery. PMID- 30286869 TI - In silico screening of anthraquinones from Prismatomeris memecyloides as novel phosphodiesterase type-5 inhibitors (PDE-5Is). AB - OBJECTIVE: Prismatomeris memecyloides Craib (Rubiaceae) is a medicinal plant traditionally used by ethnic minorities in Vietnam for the treatment of erectile dysfunction (ED). The aim of this study was to investigate the chemical compositions and screen in silico its possible inhibitory effect against PDE-5 which reduced cyclic guanosine-3',5'-monophosphate (cGMP) levels and indirectly caused the male ED. METHODS: Separation of natural compounds were carried out on chromatographic column with silica gel or reversed phase materials, eluting with different solvent gradients. The structures of all isolated compounds were elucidated on the basis of spectroscopic data (HR-MS, 1D/2D-NMR). Docking simulation study of compound (1-7) was performed by using flexible side chains protocol based on Iterated Local Search Global Optimizer Algorithm of AutoDock/Vina v.1.1.2. Pharmacokinetic parameters and toxicity prediction were also calculated by appropriate softwares. RESULTS: From the methanol extract of roots of P. memecyloides collected in Vietnam, seven compounds including four anthraquinone/one anthraquinone glycoside namely damnacanthal (1), lucidin-omega methyl ether (2), 3-methylalizarin (3), rubiadin-3-methyl ether (4), and 1-O methylrubiadin 3-O-primeveroside (5) along with two iridoid glucosides, asperulosidic acid (6) and aitchisonide A (7) were isolated. The molecular modeling results showed that 5 anthraquinone compounds possess the lowest binding energies to PDE-5. The anthraquinone glucoside 1-O-methylrubiadin 3-O primeveroside (5) potentially inhibited PDE-5 similarly to commercial PDE-5Is sildenafil (SLD) and tadalafil (TLD). Calculated pharmacokinetic results like pIC50,pred; miLogP, TPSA, enzyme inhibitory of anthraquinone glucoside (5) were similar and even higher to those of the commercial PDE-5 inhibitors. Especially the predictive toxicity of 1-O-methylrubiadin 3-O-primeveroside (5) was even lower than those of SLD and TLD. CONCLUSION: This is the first study to find a scientific-based evidence for the ethnic use of P. memecyloides as medicinal plant for the treatment of ED. The result indicates that the anthraquinones (damnacanthal (1), lucidin-omega-methyl ether (2), 3-methylalizarin (3) and rubiadin-3-methyl ether (4)), especially anthraquinone glycoside (1-O methylrubiadin 3-O-primeveroside (5)) are compounds of potential novel drug class for the ED treatment. PMID- 30286870 TI - [Effects of drug use and anxiety on premature ejaculation in a sample of Spanish drug addicts]. AB - INTRODUCTION: Premature ejaculation may be due to many factors and one of them may be drug use. AIMS: The main objective of this study is to show how drug abuse affects the ejaculatory response, keeping in mind the different substances consumed, the level of anxiety and the period of withdrawal. METHOD: Two samples were used, one for men who were addicted to drugs (N=925) and one of non consumers (N=82). Both samples were selected from 28 treatment centers. The Golombok Rust Inventory of Sexual Satisfaction (GRISS) questionnaire and the State Anxiety Trait Questionnaire (STAI) were used. RESULTS: The results show that men with a history of consumption obtain higher percentages in premature ejaculation compared to non-users (44.3%> 15.9%) and also higher mean scores in anxiety (State Anxiety=19.83>11, 89; Trait Anxiety=25.66>12.39). These differences were statistically significant (P=.000). The results confirm that the withdrawal period does not improve ejaculatory response and having a partner does not work as a protective factor in premature ejaculation. CONCLUSIONS: Men with a history of drug use are more likely to suffer from premature ejaculation and higher levels of anxiety, which does not improve during the period of withdrawal, leading to the belief that drug users have personality traits that facilitate premature ejaculation and/or that the neurological damages caused by the drugs contribute to a decrease in the intravaginal ejaculatory latency, issues that should be studied in future investigations. PMID- 30286871 TI - The effect of sleeve gastrectomy technique on women's sexual function: A prospective study. AB - INTRODUCTION: Obesity may lead to a serious deterioration in general quality of daily life and sexual functionality. Bariatric surgery is the most effective treatment method for obesity and related morbidities so far and it is better than some medical treatment modalities. In this study, we aimed to investigate the effects of bariatric surgery and especially sleeve gastrectomy, which has been currently performed in increasing numbers on female sexual functions and quality of life. MATERIALS AND METHODS: A total of 53 patients were included to the current study. The participants were selected from eligible individuals who have undergone laparoscopic sleeve gastrectomy operation in our center between April 2014 and March 2015 dates. Age, body weights and body mass indexes (BMIs) of the patients were pre-operatively recorded. The patients have completed the Female Sexual Function Index (FSFI), Beck Depression Scale and SF-36 (Short form-36) forms before and after the surgery. Additionally, post-operative decrease in body weights and mean BMI were recorded. RESULTS: Following bariatric surgery, sexual functions of the female patients improved and total FSFI scores increased. When FSFI scores were analyzed, it was observed that sexual desire, sexual arousal, lubrication, orgasm and sexual satisfaction increased, while the pain parameter has not changed. CONCLUSION: Recent literature reveals that unfavorable effects of increasingly prevalent obesity on sexual functions cannot be denied. We think that sleeve gastrectomy can obtain considerable weight loss, improvement in self esteem, decrease in anxiety, amelioration in sexual functions and general quality of life.

PMID- 30286875 TI - Editorial Commentary: Critical Shoulder Angle: Perhaps Not So "Critical" for Clinical Outcomes Following Rotator Cuff Repair. AB - The critical shoulder angle (CSA) has been associated with the development of rotator cuff pathology. More recent studies have also identified a correlation between an increased CSA and recurrent tears after arthroscopic rotator cuff repair. Although this observation is significant, several studies have failed to identify a correlation between CSA and clinical outcomes after rotator cuff repair. As a result, the usefulness of this measurement, and the need to address it with lateral acromioplasty, remains ill defined. Further research is required to demonstrate an association between CSA and clinical outcomes before treatment algorithms should be altered.

PMID- 30286878 TI - Editorial Commentary: Will New Technology Improve Outcomes or Are All-Suture Rotator Cuff Surgery Anchors Like a New Set of Golf Clubs? Not a Question for the Biomechanics Lab. AB - Failure of rotator cuff repairs may be attributed to biological, mechanical, or rehabilitative reasons. New all-suture anchors have several theoretical benefits that make them potentially attractive for use in rotator cuff repair. As their mechanical strength results from the anchor deploying as a button or molly bolt against the inner cortical bone, it stands to reason that decortication performed for the purposes of improved repair biology may be particularly detrimental to the initial time-zero biomechanics of all-suture anchors. It is unclear whether the statistically significant all-suture biomechanics seen with and without decortication translate clinically. PMID- 30286879 TI - Editorial Commentary: Biomechanics of All Suture Anchors: What We Know So Far. AB - All suture anchors (ASAs) have proven valuable for soft tissue to bone fixation. They have a small footprint and can be inserted in tight spaces where little bone is available. Additionally, more ASAs can be inserted in the same amount of bone than their larger predecessors, and this may improve the overall biomechanics of the repair construct through load sharing at multiple points of fixation. ASAs are more dependent on the cortical bone than the cancellous bone where they are inserted for fixation. Decortication of this bone should be minimized or avoided, and deployed anchors should be seated to the cortical bone as much as possible at the time of insertion to avoid later settling with cyclic loading. In anchor biomechanical studies, it is important to look at gap formation with cyclic loading. This biomechanical property is clinically more significant than catastrophic failure because of anchor pullout or suture breakage, which is uncommon. Finally, regarding shoulder rotator cuff surgery, biological (healing) is our greatest challenge; in general, anchor fixation strength is adequate.

AB - Arthroscopic reduction with osteosynthesis using bone grafting has become a successful alternative to open techniques for the treatment of chronically unstable scaphoid nonunions. Several studies have demonstrated that arthroscopic techniques are safe and reproducible in addition to causing less soft tissue damage and providing promising short- and mid-term results. However, these techniques have limitations in restoring normal carpal alignment, especially in patients with unstable scaphoid nonunion and carpal collapse deformities, although this does not affect the recovery of clinical function. Therefore, the practical goal of arthroscopic technique should be kept in mind when treating unstable scaphoid nonunions.

Developing treatments capable of restoring articular cartilage to acetabular cartilage defects is of great importance if hip preservation treatments are to be successful.

However, readers could contemplate the meaning of "clinical equivalence" and, perhaps, find themselves wanting better ways to detect differences between surgical techniques. PMID- 30286886 TI - Editorial Commentary: You Have Some (Infrapatellar Branch of the Saphenous) Nerve! AB - Infrapatellar branches of the saphenous nerve are always present at the anteromedial aspect of proximal tibia. Iatrogenic injury to these branches is a known consequence of knee surgery, be it an arthroscopic portal, harvesting of a hamstring or bone-patellar tendon-bone anterior cruciate ligament graft, or opening wedge opening high tibial osteotomy. Their anatomic course can be variable. High-resolution ultrasound may provide an improved diagnostic tool for better identification.

AB - The use of silver in various forms has been advocated for its antibacterial properties for centuries, because its toxicity to human cells is considerably lower than its toxicity to bacteria. The Greek historian Herodotus recounted how the king of Persia, before going to war, among his provisions included boiled water stored in flagons of silver, ostensibly to mitigate the risk of foodborne infections in his troops. Additionally, recent studies support the use of silver to generate an electrical stimulation for promotion of wound healing. These concepts have been combined in a proprietary postoperative dressing that is promoted to mitigate the risk of postoperative infections.

AB - Remplissage minimizes recurrence and confers minimal motion loss when applied to glenoid defects up to 20% and humeral loss up to 40% in patients with shoulder instability. However, variability in the reporting of volume of both glenoid and humeral head bone loss deters the formulation of distinct thresholds for indications and contraindication for remplissage. However, there appears to be little downside in the performance of this "biologic" solution to Hill-Sachs lesions. PMID- 30286889 TI - Editorial Commentary: Return to Sport After Surgical Treatments of the Acromioclavicular Joint Dislocation Seems to Be Almost Perfect in the Literature. AB - Systematic reviews identify completed studies that address a research question and evaluate the results of these studies to arrive at conclusions about a body of research. They should be encouraged because the findings, with power enhanced by the larger sample size available from the combined studies, often represent an important scientific contribution. The systematic review findings also can be a useful background for developing practice guidelines in the future. One of limitations of this approach is a risk of publication bias. Studies with negative results are more likely to remain unpublished or excluded from the review owing to a lack of reporting outcome of the specific interest. Although publication bias is difficult to eliminate, it should be addressed by the authors with appropriate statistical procedures that may be helpful in detecting its presence. Negative results should not be masked by overall good outcomes. This rather long caveat relates to a recent review showing that return to sport after surgical treatments of acromioclavicular joint dislocation seems to be almost perfect in the literature. Perfection is rare, so publication bias could be a limitation of the review. PMID- 30286891 TI - Free Will. PMID- 30286890 TI - Editorial Commentary: Reduce the Failure Risk: A Challenge to Reduce the Risk of Using Hybrid Graft in Anterior Cruciate Ligament Reconstruction. AB - Hybrid grafting (augmentation of small hamstring autografts with allograft tissue) is preferred by many surgeons for anterior cruciate ligament (ACL) reconstruction. Although a recent, well-conducted, systematic review reported no significant differences in failure risk between hybrid graft and autograft ACL reconstruction, a trend toward a greater failure risk using the hybrid graft existed in many of the included studies. Three potential causes of hybrid graft ACL reconstruction failure that are absent in autograft ACL reconstruction are different levels of graft revascularization and ligamentization, differences in the tendon-bone healing capacity between the allograft and autograft portions in the bone tunnel, and processing of the graft. Research advances in these areas will further reduce the failure risk of hybrid graft ACL reconstruction.

AB - PURPOSE: The goal of this study was to examine changes in contemporary patterns of marijuana use and attitudes over time. Given shifts in state-by-state marijuana legislation, there is a reason to believe that the patterns of high school seniors' marijuana use behavior and attitudes about use have changed from 2010 to 2016. METHODS: Data are from high school seniors in the 2010-2016 waves of Monitoring the Future, a nationally representative, cross-sectional survey in the United States. Latent class analysis was used to determine underlying patterns of marijuana use and related attitudes. Differences in latent class membership were examined across years, and gender and race/ethnicity were also examined. RESULTS: Five latent classes were identified: Intolerant Nonusers (49% of the sample), Tolerant Nonusers (12%), Disapproving Users (7%), Experimenters (6%), and Marijuana Enthusiasts (26%). Class prevalences remained relatively stable from 2010 to 2013; beginning in 2014 a significant decrease in prevalence was observed for Intolerant Nonusers and significant increases in prevalence were observed for Tolerant Nonusers and Marijuana Enthusiasts. Membership in the Marijuana Enthusiasts class was consistently more likely for males; Hispanic and black adolescents were more likely to be Disapproving Users. CONCLUSIONS: Contemporary patterns of marijuana use and attitudes have remained consistent over time, however, significant shifts in class prevalence emerged in 2014. Findings also suggest that a substantial subgroup of adolescents would benefit from prevention and intervention efforts targeting marijuana use and attitudes. PMID- 30286900 TI - The Prospective Association Between Electronic Device Use Before Bedtime and Academic Attainment in Adolescents. AB - PURPOSE: To examine longitudinal associations between five commonly used technology devices prior to bedtime and real-life academic outcomes in adolescents. METHODS: A total of 853 adolescents were recruited to a three-year prospective cohort study, with annual assessments. Academic grades/levels for three core subjects (English, Mathematics, and Science) were extracted from school records, and standardized (z-scores) were derived at the end of each academic year. A validated questionnaire was used to determine the frequency of using five types of technology (television viewing, video gaming, mobile telephone use, listening to music, and social networking) before bedtime. RESULTS: After adjustment, English attainment was the subject most affected by prebedtime technology use, where three of five technologies assessed were negatively and prospectively associated (social networking [beta = -.07 and p = .024], video gaming [beta = -.10 and p = .008], and mobile telephone [beta = -.07 and p=.017]). Social networking (beta = -.07and p = .042), television viewing (beta = -.08 and p = .044), and mobile telephones (beta = -.07 and p = .031) were associated with significant impairment in English for girls whereas attainment in boys was most impaired by video gaming (beta = -.12 and p = .014). CONCLUSIONS: The use of electronic devices by adolescents before bedtime may reduce their academic attainment, but apart from video gaming for boys, the negative impact of near bedtime technology use on academic performance is small. PMID- 30286902 TI - Impact of a Neuroscience-Based Health Education Course on High School Students' Health Knowledge, Beliefs, and Behaviors. AB - PURPOSE: The purpose of this pilot study was to evaluate the potential of an innovative high school neuroscience-based health course for implementation feasibility and impact on student outcomes. METHODS: Thirteen teachers from two high schools participated in this quasi-experimental pilot study including 395 students (202 in the intervention classes and 193 in the comparison classes). Students completed pre/post online surveys assessing their knowledge, beliefs, and behaviors. Our analysis strategy for multi-item measures was to estimate the effects of the intervention on latent change scores in structural equation models. RESULTS: Students in the neuroscience health classes showed a significant increase in neuroscience knowledge as compared to students in the comparison group (difference estimate in proportion correct metric, adjusted for covariates = .04; 95% confidence interval [.01, .06]). However, none of the other primary outcomes showed a significant difference between conditions. Teachers in the intervention group were observed implementing the neuroscience and health components more often than the self-regulation and growth mindset components. Students in the neuroscience group were more likely to mention the importance of caring for their brain and its link to health behaviors. CONCLUSIONS: Findings demonstrate that information about the link between health behaviors and brain functioning can be successfully integrated into a high school health education course, although effects on student health beliefs and behaviors were not observed. Additional development work should focus on clarifying the theoretical mechanisms of change, integrating the neuroscience content with self-regulation and growth mindset, and providing additional professional development for teachers. PMID- 30286901 TI - The Longitudinal Impact of Screen Time on Adolescent Development: Moderation by Respiratory Sinus Arrhythmia. AB - PURPOSE: To date, little is known about underlying psychophysiological contributions to the impact of media content and overall screen time on adolescent psychological functioning. In the present study we examine respiratory sinus arrhythmia (RSA) as a moderator of the link between specific types of media content use, overall media exposure, and the development of internalizing and aggressive symptoms in youth. METHODS: A sample of 374 adolescents (mean age = 15) reported on their media use, internalizing behavior, and aggressive behavior at time 1 (2011) and 1-year follow-up (2012). RSA reactivity was gathered during a challenging laboratory task. Path analyses were conducted to test the hypothesized three-way interaction model between media use, media content, and RSA reactivity, separately for internalizing and aggressive problems. RESULTS: Significant interactions were found for aggressive, but not prosocial, media content. For aggressive content, youth exhibiting RSA withdrawal reported significantly greater internalizing and aggressive symptoms when exposed to higher amounts of screen time and aggressive content. CONCLUSIONS: These findings suggest that profiles of heightened RSA withdrawal may place adolescents at greater risk to the negative impact of violent media, whereas prosocial media content may not significantly impact youth development of psychopathology. Implications for the role of psychophysiology in our understanding of media effects are discussed.

AB - Pre-exposure prophylaxis (PrEP) is a biomedical prevention intervention that has demonstrated high efficacy in reducing human immunodeficiency virus (HIV) transmission. While an increasing number of jurisdictions have endorsed the use of emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) for PrEP, access to PrEP varies widely. Adolescents and young adults (AYAs), especially those at high risk of HIV acquisition, such as young gay, bisexual, and other men having sex with men (YGBMSM) and individuals living in countries where HIV is endemic, face multiple barriers that limit their access to PrEP. This position paper provides context and recommendations for the promotion and use of PrEP among AYAs. PMID- 30286904 TI - Corrigendum.

PMID- 30286910 TI - Decision Making With Imaging in Asymptomatic Aortic Regurgitation. AB - The authors review the optimal sequence of multimodality imaging studies in patients with chronic asymptomatic aortic regurgitation (AR). The initial questions in evaluating such patients are: 1) is AR severe; and 2) does it significantly impact the left ventricle? Although transthoracic echocardiography is usually able to answer these questions, a cardiovascular magnetic resonance imaging study might be necessary if the data from echocardiography are conflicting or inadequate. If AR is severe and the left ventricle is severely dilated, surgery is indicated. If AR is severe but the left ventricle is not significantly impacted, echocardiographic exercise testing might unmask symptoms. If aortopathy is suspected, cardiovascular magnetic resonance (in younger patients) or computed tomography (in older patients) is necessary. In cases where AR severity or mechanism are unclear and no additional tests are possible, or if there is a potential for aortic valve repair, transesophageal echocardiography is appropriate. Finally, it is good practice to define a follow-up plan with the patient and referring physician, with an explanation as to what can be expected in the future.

PMID- 30286911 TI - Imaging in Heart Transplant Patients. AB - Heart transplantation is an accepted treatment for select patients with end-stage heart failure. Improvements to immunosuppressive therapies and patient management have increased the half-life of heart transplant patients to over 10 years. Despite this success, rejection remains the "Achilles heel" of heart transplantation. The early detection of acute rejection and cardiac allograft vasculopathy are paramount to avoiding graft loss. Unlike in kidney and liver transplantation, there are no clinically validated biomarkers for detecting heart transplant rejection. Existing methods for monitoring the cardiac allograft are invasive. The endomyocardial biopsy is the standard-of-care for monitoring for acute rejection but carries risks of complications, and histologic assessment is often subjective. Equally, intracoronary angiography remains the standard-of-care for detecting cardiac allograft vasculopathy, but it is invasive and less than ideally sensitive. Newer echocardiographic techniques, computed tomography, magnetic resonance, and positron emission tomography are less invasive than conventional biopsy and show promise in excluding rejection thereby potentially decreasing the frequency of biopsies in low-risk patients. Intravascular ultrasonography and optical coherence tomography, although still invasive, improve on the assessment of the coronary tree through increased resolution, evaluation of the microvasculature, and visualization of the vessel wall. This review outlines the invasive and noninvasive imaging modalities that are employed in the routine care of heart transplant patients and examines newer techniques that are under evaluation.

PMID- 30286918 TI - Genetic Variants in SGLT1, Glucose Tolerance, and Cardiometabolic Risk. AB - BACKGROUND: Loss-of-function mutations in the SGLT1 (sodium/glucose co transporter-1) gene result in a rare glucose/galactose malabsorption disorder and neonatal death if untreated. In the general population, variants related to intestinal glucose absorption remain uncharacterized. OBJECTIVES: The goal of this study was to identify functional SGLT1 gene variants and characterize their clinical consequences. METHODS: Whole exome sequencing was performed in the ARIC (Atherosclerosis Risk in Communities) study participants enrolled from 4 U.S. communities. The association of functional, nonsynonymous substitutions in SGLT1 with 2-h oral glucose tolerance test results was determined. Variants related to impaired glucose tolerance were studied, and Mendelian randomization analysis of cardiometabolic outcomes was performed. RESULTS: Among 5,687 European-American subjects (mean age 54 +/- 6 years; 47% male), those who carried a haplotype of 3 missense mutations (frequency of 6.7%)-Asn51Ser, Ala411Thr, and His615Gln-had lower 2-h glucose and odds of impaired glucose tolerance than noncarriers (beta coefficient: -8.0; 95% confidence interval [CI]: -12.7 to -3.3; OR: 0.71; 95% CI: 0.59 to 0.86, respectively). The association of the haplotype with oral glucose tolerance test results was consistent in a replication sample of 2,791 African American subjects (beta = -16.3; 95% CI: -36.6 to 4.1; OR: 0.39; 95% CI: 0.17 to 0.91) and an external European-Finnish population sample of 6,784 subjects (beta = -3.2; 95% CI: -6.4 to -0.02; OR: 0.81; 95% CI: 0.68 to 0.98). Using a Mendelian randomization approach in the index cohort, the estimated 25-year effect of a reduction of 20 mg/dl in 2-h glucose via SGLT1 inhibition would be reduced prevalent obesity (OR: 0.43; 95% CI: 0.23 to 0.63), incident diabetes (hazard ratio [HR]: 0.58; 95% CI: 0.35 to 0.81), heart failure (HR: 0.53; 95% CI: 0.24 to 0.83), and death (HR: 0.66; 95% CI: 0.42 to 0.90). CONCLUSIONS: Functionally damaging missense variants in SGLT1 protect from diet-induced hyperglycemia in multiple populations. Reduced intestinal glucose uptake may protect from long term cardiometabolic outcomes, providing support for therapies that target SGLT1 function to prevent and treat metabolic conditions.

AB - BACKGROUND: Diabetic medications can cause hypoglycemia, which may lead to myocardial damage. OBJECTIVES: This study sought to determine whether hypoglycemia is associated with higher levels of high-sensitivity cardiac troponin T (hsTnT). METHODS: The BARI 2D (Bypass Angioplasty Revascularization Investigation 2 Diabetes) trial randomized patients with type 2 diabetes mellitus and stable coronary artery disease, and closely followed them for hypoglycemia over the first year. Hypoglycemia was classified by maximum severity and frequency. hsTnT was measured at baseline and 1 year, and analyzed using multivariable regression. RESULTS: Of 1,984 patients, follow-up hypoglycemia was absent in 1,026 (52%) patients, mild in 875 (44%), and severe in 83 (4%), and occurred less than weekly in 561 (28%) and greater than or equal to weekly in 397 (20%). hsTnT levels were associated with hypoglycemia: a median of 11.4 ng/l (interquartile range [IQR]: 8.1 to 17.3 ng/l) for none, 12.5 ng/l (IQR: 8.3 to 19.3 ng/l) for mild, and 13.7 ng/l (IQR: 9.9 to 24.9 ng/l) for severe hypoglycemia (p = 0.0001); and 12.5 ng/l (IQR: 8.3 to 18.1 ng/l) for less than weekly and 13.0 ng/l (IQR: 8.8 to 21.1 ng/l) for greater than or equal to weekly hypoglycemia (p = 0.0013). Severe hypoglycemia was associated with 34% higher 1 year hsTnT levels (p < 0.0001) in unadjusted analysis, 17% higher (p = 0.006) after adjustment for baseline factors unrelated to diabetes, and 6% higher (p = 0.23) after further adjustment for the duration and severity of diabetes. Hypoglycemia greater than or equal to weekly was associated with 14% higher hsTnT (p = 0.0003) in unadjusted analysis, 12% higher (p = 0.0002) after adjustment for baseline factors unrelated to diabetes, and 4% higher (p = 0.16) after adjustment for diabetes related factors. CONCLUSIONS: Hypoglycemia was associated with elevated hsTnT levels, but this may be due to more severe diabetes in patients who developed hypoglycemia, rather than the direct result of hypoglycemia.

AB - BACKGROUND: The optimal treatment strategy when combining antiplatelets with oral anticoagulants in patients with atrial fibrillation (AF) and myocardial infarction (MI) or undergoing percutaneous coronary intervention (PCI) is unknown. OBJECTIVES: The authors investigated the risk of bleeding, ischemic stroke, MI, and all-cause mortality associated with direct oral anticoagulants (DOACs) compared with vitamin K antagonists (VKAs) in combination with aspirin, clopidogrel, or both in patients with AF following MI and/or PCI. METHODS: Danish nationwide registries were used to identify patients with AF who were admitted with a MI and/or underwent PCI, between August 2011 and June 2017, treated with OAC in combination with antiplatelet(s). Patients were followed for 12 months or until an outcome, study end, or death. Standardized absolute risks were estimated on the basis of outcome-specific Cox regression models adjusted for potential confounders. Average treatment effects were obtained as standardized absolute risk differences (ARD) in risks at 3 and 12 months using the g-formula. RESULTS: Overall, 3,222 patients were included in the study population, of which 875 (27%) were treated with VKA+single antiplatelet therapy (SAPT), 595 (18%) were treated with DOAC+SAPT, 1,074 (33%) were treated with VKA+dual antiplatelet therapy (DAPT), and 678 (22%) were treated with DOAC+DAPT. At 3 months, there was a significant difference in the absolute risk of MI associated with DOAC+SAPT compared with VKA+SAPT (3-month ARD -1.53% (95% confidence interval: -3.08% to 0.11%), with no significant differences found regarding bleeding, ischemic stroke, and all-cause mortality. Compared with VKA+DAPT, DOAC+DAPT was associated with a significantly reduced risk of bleeding (3-month ARD -1.96%, 95% confidence interval: -3.46% to -0.88%), with no significant difference in the absolute risk of all-cause mortality, stroke, or MI. CONCLUSIONS: In a real-world population of AF patients with MI and/or after PCI, the authors found that DOAC in combination with DAPT was associated with a significantly decreased risk of bleeding and similar thromboembolic protection compared with VKA in combination with DAPT.

AB - BACKGROUND: Primary cardiac affection is common and is a major cause of death in systemic sclerosis (SSc), but there are knowledge gaps regarding the effect of cardiac dysfunction on mortality. OBJECTIVES: The purpose of this study was to evaluate diastolic function in a large, unselected SSc cohort and assess the effect of diastolic dysfunction (DD) on mortality. METHODS: SSc patients followed prospectively at the Oslo University Hospital from 2003 to 2016 with available echocardiographies and matched control subjects were included. DD was assessed by echocardiography according to the 2016 American Society of Echocardiography/European Association of Cardiovascular Imaging guidelines. Pulmonary hypertension (PH) was diagnosed by right heart catheterization. Vital status was available for all patients. Cox regression analyses with hazards ratios (HRs) were conducted. RESULTS: Diastolic function was assessed in 275 SSc patients at baseline and in 186 patients at follow-up. At baseline, 46 of the 275 SSc patients (17%) were diagnosed with DD and 195 (71%) had normal diastolic function. After a median follow-up of 3.4 years (interquartile range: 1.6 to 6.2 years), the proportion of DD increased from 17% to 29%. During follow-up, 57% of patients with DD at baseline died, compared with 13% of patients with normal diastolic function. At baseline, 86 patients had performed right heart catheterization, and 43 were diagnosed with PH; of these 60% deceased. In multivariable Cox regression analyses, DD was a stronger predictor of death (HR: 3.7; 95% CI: 1.69 to 8.14; c-index 0.89) than PH (HR: 2.0; 95% CI: 1.1 to 3.9; c index 0.84). CONCLUSIONS: DD is frequent in SSc, and the presence of DD is associated with high mortality. DD exceeds PH with respect to predicting mortality.

AB - BACKGROUND: Data related to the epidemiology and resource utilization of congenital heart disease (CHD)-related emergency department (ED) visits in the pediatric population is limited. OBJECTIVES: The purpose of this analysis was to describe national estimates of pediatric CHD-related ED visits and evaluate medical complexity, admissions, resource utilization, and mortality. METHODS: This was an epidemiological analysis of ED visit-level data from the 2006 to 2014 Nationwide Emergency Department Sample. Patients age <18 years with CHD were identified using International Classification of Diseases-9th Revision-Clinical Modification codes. We evaluated time trends using weighted regression and tested the hypothesis that medical complexity, resource utilization, and mortality are higher in CHD patients. RESULTS: A total of 420,452 CHD-related ED visits (95% confidence interval [CI]: 416,897 to 422,443 visits) were identified, accounting for 0.17% of all pediatric ED visits. Those with CHD were more likely to be <1 year of age (43% vs. 13%), and to have >=1 complex chronic condition (35% vs. 2%). CHD-related ED visits had higher rates of inpatient admission (46% vs. 4%; adjusted odds ratio: 1.89; 95% CI: 1.85 to 1.93), higher median ED charges ($1,266 [interquartile range (IQR): $701 to $2,093] vs. $741 [IQR: $401 to $1,332]), and a higher mortality rate (1% vs. 0.04%; adjusted odds ratio: 1.25; 95% CI: 1.07 to 1.45). Adjusted median charges for CHD-related ED visits increased from $1,219 (IQR: $673 to $2,138) to $1,630 (IQR: $901 to $2,799), while the mortality rate decreased from 1.13% (95% CI: 0.71% to 1.52%) to 0.75% (95% CI: 0.41% to 1.09%) over the 9 years studied. CONCLUSIONS: Children with CHD presenting to the ED represent a medically complex population at increased risk for morbidity, mortality, and resource utilization compared with those without CHD. Over 9 years, charges increased, but the mortality rate improved. PMID- 30286927 TI - Big Data for Little Hearts. PMID- 30286928 TI - Blood Sugar Regulation for Cardiovascular Health Promotion and Disease Prevention: JACC Health Promotion Series. AB - The primary objective of this study was to analyze the most up-to-date evidence regarding whether and how blood sugar regulation influences cardiovascular health promotion and disease prevention by carrying out an umbrella review. Three separate, systematic literature searches identified 2,343 papers in total. Overall, 44 studies were included for data extraction and analysis. The included systematic reviews and meta-analyses published between January 1, 2016, and December 31, 2017, were of good to very good quality (median Overview Quality Assessment Questionnaire score = 17). Identified evidence suggests that cardiovascular disease (CVD) prevention services should consider regulation of blood glucose as a key target for intervention. Furthermore, the recommendations for effective intervention and service development/training described here for prevention of CVD should be adopted into evidence-based practice guidelines. Multidisciplinary teams should be formed to deliver multicomponent interventions in community-based settings. There may be substantial opportunities for integrating CVD and diabetes prevention services. PMID- 30286930 TI - The ACC Is Your Advocate.

AB - Type 2 diabetes mellitus (T2D) is a major risk factor for cardiovascular disease (CVD), the most common cause of death in T2D. Despite improved risk factor control, however, adults with T2D continue to experience substantial excess CVD risk. Until recently, however, improved glycemic control has not been associated with robust macrovascular benefit. The advent of 2 new classes of antihyperglycemic agents, the sodium-glucose cotransporter-2 inhibitors and the glucagon-like peptide-1 receptor agonists, and their respective large cardiovascular outcome trials, has led to a paradigm shift in how cardiologists and heath care practitioners conceptualize T2D treatment. Herein, the authors review the recent trial evidence, the potential mechanisms of action of the sodium-glucose cotransporter-2 inhibitors and the glucagon-like peptide-1 receptor agonists, safety concerns, and their use for the primary prevention of CVD as well as in diabetic patients with impaired renal function and heart failure.

A NSQIP analysis of anesthesia time and complications following tracheostomy placement. AB - BACKGROUND: Increased anesthesia time may lead to respiratory complications in patients receiving tracheostomy, which contributes to patient morbidity. METHODS: The American College of Surgeon's National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for cases of planned tracheostomy (CPT 31600) from 2005 to 2012. Patients were stratified into quintiles based on anesthesia duration. Pearson's chi square, Fischer's exact test, one-way ANOVA, and multivariate regression were used to determine the association between patient characteristics with pneumonia and ventilator dependence. RESULTS: Out of 752 patients, 83 patients experienced post-operative pneumonia, and 166 experienced ventilator dependence. Following multivariate regression analysis, anesthesia quintiles were not significantly associated with pneumonia or ventilator dependence. Age (OR 1.03, 95% CI 1.00-1.05, P = .032), dyspnea (OR 2.21, 95% CI 1.18-4.13; P = .013), pre-operative ventilator dependence (OR 3.08, 95% CI 1.19 7.98; P = .020), and sepsis (OR 6.68, 95% CI 3.19-14.0; P < .001) remained as significant predictors of post-operative ventilator dependence. CONCLUSIONS: Faster may not be better-- prolonged anesthesia time does not increase the risk of post-operative pneumonia or ventilator dependence in patients receiving a planned tracheostomy in the operating room.

AB - Early-stage non-small cell lung cancer (NSCLC) is on the rise due to the implementation of screening guidelines for patients at risk for developing lung cancer. It is anticipated that as the US population continues to age, there will be a higher percentage of medically inoperable early-stage lung cancer patients. For this reason, noninvasive ablative therapies are necessary. Stereotactic body radiation therapy (SBRT) is an effective modality in addressing early-stage NSCLC. SBRT consists of high-dose radiation delivered over 3-5 treatments. Several randomized trials comparing surgery to SBRT in early-stage operable patients have unfortunately closed early due to poor accrual. However, a recent pooled analysis from 2 randomized trials (StereoTActic Radiotherapy and Radiosurgery Or Surgery for operable Early-stage non-small cell Lung cancer) comparing surgery to SBRT did show comparable local control and overall survival rates between surgery and SBRT, offering a very effective, noninvasive modality for older adult patients with early-stage NSCLC. In this review, we summarize the role of SBRT in early-stage NSCLC, in particularly applied to the older adult population.

AB - PURPOSE: To (1) analyze verbatim wording used by adults who stutter (AWS) to self disclose stuttering, (2) determine contexts in which AWS may self-disclose, (3) examine the use of self-disclosure by AWS about other aspects of their identity, and (4) investigate the ways in which speech-language pathologists (SLPs) develop self-disclosure statements with AWS. METHOD: Web-based questionnaires were administered to AWS (N = 42) and SLPs (N = 33) who work with AWS. The AWS questionnaire asked about the verbatim wording of self-disclosure statements used by AWS and the contexts in which they utilize them. For SLPs, the questionnaire probed how and why they work with AWS to formulate self-disclosure statements. Responses were openly coded and then funneled into concepts for analysis. RESULTS: The majority of AWS provided verbatim self-disclosure statements which were educational in nature. However, when responding to fixed choices and when reporting on self-disclosing other aspects of their lives, the majority of participants selected a direct statement. The majority of AWS reported that they self-disclose when interviewing for a job. SLPs reportedly instruct their clients to use educational self-disclosure statements. SLPs also reported that they use an individualized approach to brainstorming self-disclosure statements. Finally, SLPs reported that they find self-disclosure beneficial because it facilitates self-empowerment for AWS. CONCLUSION: AWS may benefit from learning about the type of self-disclosure statements and the contexts in which other AWS chose to disclose. Additionally, SLPs who work with AWS may benefit from the reported procedures for and types of self-disclosure statements formulated by AWS.

AB - OBJECTIVE: To assess the rates and distribution of first recurrence in patients with FIGO stage IIIC1 endometrial cancer (EC) who did not undergo paraaortic dissection at surgical staging. METHODS: We retrospectively selected all (n = 207) stage IIIC1 patients treated at a single institution from 5/1993-1/2017. Sites of first recurrence were identified, disease-free (DFS) and overall survival (OS) calculated, multivariate logistic regression performed to identify factors associated with recurrence. RESULTS: Three-year DFS and OS were 66.5% and 85.7%, respectively. The most common histology was endometroid (64.2%). Three year DFS was 81% (SE+/-3.8%) endometrioid vs. 39.5% (SE+/-6.6%) non-endometrioid (P < 0.001). Three-year OS was 96.9% (SE+/-1.8%) endometrioid vs. 65.6% (SE+/ 6.7%) non-endometrioid (P < 0.001). Sixty-two (30.1%) patients recurred. Patterns of recurrence were: 14 (8.3%) multiple sites, 17 (8.2%) abdominal, 14 (6.8%) extra-abdominal, 17 (8.3%) isolated nodal (8 of these (3.9%) paraaortic). Patients with isolated tumor cells (ITCs) in lymph nodes only had 12/71 (17%) recurrence rate vs. 50/135 (37%) for patients with micro-/macrometastasis. On univariate analysis, grade (HR 4.67 95%CI 1.5-14.5, P = 0.008), histology (HR 4.9 95%CI 2.6-9.3, P < 0.001), myometrial invasion (HR 1.9 95%CI 1.04-3.5, P = 0.04), pelvic washing (HR 2.2 95%CI 1.1-4.5, P = 0.03), tumor volume in pelvic LNs (ITC vs. micro-/macrometastasis; HR 0.3 95%CI 0.2-0.7, P = 0.003) were associated with recurrence. On multivariate analysis, only histology was associated with recurrence (HR 7.88 95%CI 3.43-18.13, P < 0.001). CONCLUSIONS: Isolated paraaortic recurrence in stage IIIC1 EC is uncommon. Micro-/macrometastasis were associated with twice the recurrence rate compared to ITC. These data will help clinicians counsel patients with stage IIIC1 EC regarding paraaortic assessment. PMID- 30286947 TI - Etomidate as an Induction Agent in Sepsis. AB - Sepsis is a life-threatening response to infection often times requiring endotracheal intubation in critically ill patients. Etomidate is routinely used as an intravenous induction agent to provide sedation and amnesia before placing an endotracheal tube. Although etomidate has many favorable qualities, there is a major concern regarding the predictable adrenal insufficiency that follows its use. Controversy continues to this day as to whether etomidate should be avoided in the setting of sepsis or septic shock. PMID- 30286948 TI - Systematic Review of Systemic Therapies and Therapeutic Combinations with Local Treatments for High-risk Localized Prostate Cancer. AB - CONTEXT: Systemic therapies, combined with local treatment for high-risk prostate cancer, are recommended by the international guidelines for specific subgroups of patients; however, for many of the clinical scenarios, it remains a research field. OBJECTIVE: To perform a systematic review, and describe current evidence and perspectives about the multimodal treatment of high-risk prostate cancer. EVIDENCE ACQUISITION: We performed a systematic review of PubMED, Embase, Cochrane Library, European Society of Medical Oncology/American Society of Clinical Oncology Annual proceedings, and clinicalTrial.gov between January 2010 and February 2018 following the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement. EVIDENCE SYNTHESIS: Seventy-seven prospective trials were identified. According to multiple randomized trials, combining androgen deprivation therapy (ADT) with external-beam radiotherapy (EBRT) outperforms EBRT alone for both relapse-free and overall survival. Neoadjuvant ADT did not show significant improvement compared with prostatectomy alone. The role of adjuvant ADT after prostatectomy in patients with high-risk disease is still debated, with lack of data from phase 3 trials in pN0 patients. Novel androgen pathway inhibitors have been tested only in early-phase trials in addition to primary treatment. GETUG 12, RTOG 0521, and nonmetastatic subgroup of the STAMPEDE trial showed improved relapse-free survival for docetaxel in patients treated with EBRT plus ADT, although mature metastasis-free survival data are still pending. Both the SPCG-12 and the VACSP#553 trial showed no improvement in relapse-free survival for adjuvant docetaxel after prostatectomy. CONCLUSIONS: In contrast to the clearly demonstrated survival benefits of long-term adjuvant ADT when used with EBRT, its role after prostatectomy remains unclear especially in pN0 patients. Adding docetaxel to EBRT-ADT improves relapse-free survival, with immature results on overall survival. Novel androgen receptor pathway inhibitors are currently being tested in the neoadjuvant and adjuvant setting. PATIENT SUMMARY: Treatment of high-risk prostate cancer is based on a multimodality approach that includes systemic treatments. The best treatment or therapy combination remains to be defined. PMID- 30286949 TI - Acceleration of Bone Defect Healing and Regeneration by Low-Intensity Ultrasound Radiation Force in a Rat Tibial Model. AB - The objective was to evaluate the effect of low-intensity pulsed ultrasound (LIPUS)-induced acoustic radiation force on trabecular bone defect repair and healing in a rat tibial model. A uniform surgical defect, 3.5 mm in diameter, was generated in the proximal bilateral tibial region of rats (N = 20). LIPUS was applied to the defects in the left tibia for 20 min every day for 2 wk. Contralateral defects in the right tibia served as a control without active LIPUS treatment. The micro-computed tomography data revealed that LIPUS-treated tibia exhibited higher bone volume/total volume, connectivity density, trabecular number, and bone mineral density and significantly lower trabecular separation. Histomorphometry analysis indicated a similar trend. Mechanical testing data revealed that LIPUS treatment significantly increased bone stiffness relative to that of the control group. Short-term (2-wk) LIPUS therapy initiated trabecular bone repair and regeneration in large trabecular bone defects, whereas cortical bone remained in the initial non-mineralization stage. PMID- 30286950 TI - Shear Wave Elastography of Peripheral Muscle Weakness in Patients with Chronic Congestive Heart Failure. AB - Forty-five study participants (28 chronic heart failure [CHF] patients and 17 control participants) were prospectively enrolled in this study to investigate the clinical potential of ultrasound shear wave elastography (SWE) in identifying peripheral muscle weaknesses in chronic heart failure patients. Muscle stiffness in the gastrocnemius muscle during extension (stretch) and the lower arm flexor muscles during flexion was assessed via shear wave elastography, measuring the shear modulus (kPa) for the resting and contractile states in a range of 0-300 kPa. Resting kPa revealed no significant difference between CHF and CP, but exercise kPa for extension and flexion was significantly lower in CHF than CP. The area under the receiver operating characteristic curve of the denominator kPa Exercise stretch was 0.916, associated with a sensitivity of 89%, a specificity of 71% and a corresponding cutoff value of 81.1 kPa. Shear wave elastography is thus a reproducible and sensitive ultrasound method for evaluating peripheral muscle deficits in patients with CHF. PMID- 30286951 TI - Impulsiveness and burn patients. AB - OBJECTIVE: Impulsiveness is a tendency to act quickly based on a whim without reflection or consideration of consequences. We studied its correlations with burn variables and mental disorders among burn patients. METHODS: Consecutive acute burn patients (N=107) admitted to the Helsinki Burn Center were assessed with the Structured Clinical Interview for DSM-IV mental disorders (SCID) at baseline and at 6 months. All patients filled out the 30-item Barratt Impulsiveness Scale (BIS-11), the most commonly administered self-report measure and a standard point of reference in research on impulsiveness. RESULTS: The mean total score of BIS-11 was 64.5 (range 41.0-87.8, SD+/-6.9). There was not a significant correlation between impulsiveness and a range of characteristics of burn injury (all p-values>0.05). We found a significant correlation between some pre-burn mental disorders and impulsiveness, alcohol dependence and attentional impulsiveness (OR=1.22, p=0.022), any personality disorder and non-planning impulsiveness (OR=1.21, p=0.005), and antisocial personality disorder and motor impulsiveness (OR=1.35, p=0.043). Patients with high impulsiveness (total score >65) more often than those with low impulsiveness (<=65), had pre-burn mental disorders such as major depressive disorder (22.6% vs. 8.6%, p=0.046), alcohol dependence (46.9% vs. 25.9%, p=0.023), or other substance dependence (12.2% vs. 1.7%, p=0.028). CONCLUSION: Impulsiveness had a significant correlation with mental disorders but not with burn-related variables. Therefore the role of impulsiveness in burn injuries should not be investigated independently without first accounting for the role of mental disorders. PMID- 30286952 TI - Synthesis, biological evaluation and molecular modeling of a novel series of fused 1,2,3-triazoles as potential anti-coronavirus agents. AB - Synthesis and biological evaluation of a novel library of fused 1,2,3-triazole derivatives are described. The in-house developed multicomponent reaction based on commercially available starting materials was applied and broad biological screening against various viruses was performed, showing promising antiviral properties for compounds 14d, 14n, 14q, 18f and 18i against human coronavirus 229E. Further in silico studies identified the key molecular interactions between those compounds and the 3-chymotrypsin-like protease, which is essential to the intracellular replication of the virus, supporting the hypothesis that the protease is the target molecule of the potential antiviral derivatives. PMID- 30286953 TI - Aspergillus fumigatus phospholipase D may enhance reactive oxygen species production by accumulation of histone deacetylase 6. AB - Aspergillus fumigatus, an airborne pathogen, causes many diseases, including aspergilloma, invasive aspergillosis, and allergic bronchopulmonary aspergillosis. Phospholipase D (PLD) is an important virulence factor for A. fumigatus infection, but the manner by which PLD contributes to the virulence of this pathogen is not clear. Our results show that expression of A. fumigatus PLD in human cells was able to increase the production of reactive oxygen species (ROS), which play an important role in several signaling pathways as well as in lung infection. Meanwhile, A. fumigatus PLD was found to interact with human endogenous histone deacetylase 6 (HDAC6), a known regulator of ROS production and inflammatory responses; PLD significantly increased the expression level of HDAC6 protein without altering its mRNA level. These results suggest that A. fumigatus PLD may enhance the production of ROS via the accumulation of HDAC6, which may be involved in host immunomodulation during A. fumigatus infection. PMID- 30286954 TI - The role of UNC5b in ox-LDL inhibiting migration of RAW264.7 macrophages and the involvement of CCR7. AB - The formation of macrophage foam cells by ingesting ox-LDL and focal retention in the subendothelial space are the hallmarks of the early atherosclerotic lesion. The C-C chemokine receptor type 7 (CCR7) is positively correlated with the macrophage migration. But the mechanism of CCR7 regulation is not fully clearness. In the present study, we demonstrates that expression in UNC5b and netrin-1 was enhanced in respond to ox-LDL in Raw264.7 macrophage and associated with decreasing cell migration. Interestingly, it was found that ox-LDL significantly downregulate CCR7 gene expression. The expression of CCR7 in mRNA and protein levels were decreased in ox-LDL treated Raw264.7 macrophage when we over expression of UNC5b with pcDNA3.1-UNC5b plasmid. We got the inverse results after silence UNC5b gene with siUNC5b. Meanwhile, the data show that in ox-LDL inducement, UNC5b down-regulated CCR7, and then inhibited macrophage migration. This novel phenomenon is of a crucial highlights to understand deeply the pathogenesis of atherosclerosis. The molecular mechanism of CCR7 regulation deserves intensive study. PMID- 30286956 TI - Serum thyroid hormones levels are significantly decreased in pregnant rats with acute pancreatitis. AB - Acute pancreatitis in pregnancy (APIP), which was thought to be a rare but severe disease, with a high perinatal mortality among maternal-fetuses. Our research aimed to study and assess thyroid injury in a rat model of APIP and its possible mechanisms. The APIP model was established by retrograde injection with sodium taurocholate. Sham-operated (SO) and APIP groups were performed at 3 time-points. Histological changes in the maternal thyroid and pancreas were assessed. The activities of serum amylase, lipase and levels of FT3, FT4, MDA, TNF-alpha and IL 1beta were detected in maternal rats, and the expression of MIF, ICAM-1 and CD68 in the maternal thyroids were determined. In this study, maternal thyroid injury as well as pancreas injury occurred in a time-dependent manner. The activities of serum amylase, lipase and levels of MDA, TNF-alpha and IL-1beta were markedly increased in acute pancreatitis rats, the levels of serum FT3 and FT4 were obviously decreased in APIP groups, and the expressions of MIF, ICAM-1 and CD68 were significantly increased in the thyroid of the APIP group. Ultrastructural thyroid injuries were observed in the APIP group. Our research suggests that thyroid injury is involved in the rat experimental model of APIP. The degree of thyroid dysfunction is associated with APIP, which may affect the prognosis of acute pancreatitis. PMID- 30286955 TI - Adherens junction-associated pores mediate the intercellular transport of endosomes and cytoplasmic proteins. AB - Intercellular endosomes (IEs) are endocytosed vesicles shuttled through the adherens junctions (AJs) between two neighboring epidermal cells during Drosophila dorsal closure. The cell-to-cell transport of IEs requires DE-cadherin (DE-cad), microtubules (MTs) and kinesin. However, the mechanisms by which IEs can be transported through the AJs are unknown. Here, we demonstrate the presence of AJ-associated pores with MTs traversing through the pores. Live imaging allows direct visualization of IEs being transported through the AJ-associated pores. By using an optogenetic dimerization system, we observe that the dimerized IE kinesin complexes move across AJs into the neighboring cell. The AJ-associated pores also allow intercellular movement of soluble proteins. Importantly, most epidermal cells form dorsoventral-oriented two-cell syncytia. Together, we present a model in which an AJ-associated pore mediates the intercellular transport of IEs and proteins between two cells in direct contact. PMID- 30286958 TI - Common Etiologies of Upper Extremity Spasticity. AB - Spasticity is a motor disorder that manifests as a component of the upper motor neuron syndrome. It is associated with paralysis and can cause significant disability. The most common causes leading to spasticity include stroke, traumatic brain injury, multiple sclerosis, spinal cord injury, and cerebral palsy. This article discusses the pathophysiology and clinical findings associated with each of the most common etiologies of upper extremity spasticity. PMID- 30286957 TI - Intrathecal circHIPK3 shRNA alleviates neuropathic pain in diabetic rats. AB - Neuropathic pain is one of the most common diabetic complications and significantly decrease the quality of life. The aetiology of the painful diabetic neuropathic pain is not fully clear. Circular RNAs (circRNAs) have been identified as miRNA sponges and involved in various biological processes, including pain. CircHIPK3 is a circRNA that have been shown to be an oncogene or tumor suppressor to regulate cancer cells growth by sponging multiple miRNAs. However, the role of circHIPK3 in diabetic neuropathic pain remains unknown. The aim of the present study was to elucidate the possible role of circHIPK3 in the control of diabetic neuropathic pain. We found that circHIPK3 are highly abundant in serum from diabetes patients who suffered from neuropathic pain and in dorsal root ganglion from STZ-induced diabetes rats. Upregulation of circHIPK3 was positively associated with grade neuropathic pain in patients with type 2 diabetes. Silencing circHIPK3 alleviated neuropathic pain in diabetic rats, which was involved in neuroinflammation. Further mechanistic investigation demonstrated that circHIPK3 interacted with miR-124 and negatively regulated its expression. MiR-124 inhibitor can reverse circHIPK3 knockdown-mediated alleviation of neuropathic pain and inhibition of neuroinflammation in diabetic rats. We present the first evidence that intrathecal circHIPK3 shRNA treatment can be used to treat neuropathic pain of diabetic rats. PMID- 30286959 TI - Assessment of the Spastic Upper Limb with Computational Motion Analysis. AB - This article presents the current status of integrating 3-dimensional motion analysis and electromyography to assess upper extremity function clinically. The authors used their approach to establish a normative database for 5 Shriners Hospital Upper Extremity Evaluation tasks, which provides ranges of motion at the point of task achievement. Also, the inter-joint correlations are provided to understand the movement coordination required for each task. Distal upper extremity motion is strongly related to proximal function, supporting the idea that treatment of the proximal upper extremity deficits may be best preceded by treatment of the more distal upper extremity segments. PMID- 30286960 TI - Nonsurgical Treatment Options for Upper Limb Spasticity. AB - There are many nonsurgical treatment options for patients with upper limb spasticity. This article presents an algorithmic approach to management, encompassing evidence-based rehabilitation therapies, medications, and promising new orthotic and robotic innovations. PMID- 30286961 TI - Considerations in the Management of Upper Extremity Spasticity. AB - Spasticity is a movement disorder characterized by a velocity-dependent increase in muscle tone and a hyperexcitable stretch reflex. Common causes of spasticity include cerebral palsy, spinal cord injury, and stroke. Surgical treatment plans for spasticity must be highly individualized and based on the characteristics of patients and the spasticity in order to maximize functional gains. Candidates for surgery must be carefully selected. In this article, the authors review the pathophysiology of spasticity and discuss general considerations for surgical management with an emphasis on patient factors and spasticity characteristics. Specific considerations for the common causes of spasticity are presented. PMID- 30286962 TI - Surgical Management of Spasticity of the Thumb and Fingers. AB - Spasticity of the hand profoundly limits an individual's independent ability to accomplish self-care and activities of daily living. Surgical procedures should be tailored to patients' needs and functional ability, and even patients with severe cognitive injuries and poor upper extremity function may benefit from surgery to improve appearance and hygiene. Careful preoperative examination and planning are needed, and consideration is given to the potential unintended detrimental effect of a surgical procedure on hand function. PMID- 30286963 TI - Surgical Management of Spasticity of the Forearm and Wrist. AB - Upper extremity spasticity may result from a variety of types of brain injury, including cerebral palsy, stroke, or traumatic brain injury. These conditions lead to a predictable pattern of forearm and wrist deformities caused by opposing spasticity and flaccid paralysis. Upper extremity spasticity affects all ages and sociodemographics and is a complex clinical problem with a variety of treatment options depending on the patient, the underlying disease process, and postoperative expectations. This article discusses the cause, diagnosis, operative planning, operative techniques, postoperative outcomes, and rehabilitation protocols for the spastic wrist and forearm. PMID- 30286964 TI - Surgical Management of Spasticity of the Elbow. AB - A spastic limb refers to one with increased tone. This commonly results from an upper motor neuron injury, which, in turn, leads to disinhibition of reflex arcs. At the level of the elbow, affected individuals typically exhibit a flexion posture secondary to spastic contracture of the biceps, brachialis, and brachioradialis muscles. Surgical treatment aims to improve access for hygiene, function, and cosmetic appearance of the affected limb. The specific surgical intervention performed depends on the degree of elbow flexion contracture and whether there is an associated joint contracture or soft tissue deficit. PMID- 30286965 TI - Surgical Management of Spasticity of the Shoulder. AB - Although spastic conditions often involve the shoulder, it is rare for surgical intervention to be required. In cases in which chemodenervation and therapy are insufficient to optimize the patient's function or minimize their care requirements, surgical options, such as tendon and joint releases, can be considered. Tendon transfers are rarely indicated. Nerve transfers, particularly contralateral C7, may play a larger role in the future as we gain further understanding into the risks, indications, and contraindications of this exciting technique. PMID- 30286966 TI - Management of Joint Contractures in the Spastic Upper Extremity. AB - Upper extremity contractures in the spastic patient may result from muscle spasticity, secondary muscle contracture, or joint contracture. Knowledge of the underlying cause is critical in planning successful treatment. Initial management consists of physical therapy and splinting. Botulinum toxin can be helpful, as a therapeutic treatment in relieving spasticity and as a diagnostic tool in determining the underlying cause of the contracture. Surgical management options include release or lengthening of the causative muscle/tendon unit and joint capsular release, as required. Postoperative splinting is important to maintain the improved range of motion and protect any associated tendon lengthening or transfer. PMID- 30286967 TI - Technical Pearls of Tendon Transfers for Upper Extremity Spasticity. AB - Tendon transfers are an important surgical option when treating patients with muscular imbalance due to upper extremity spasticity. A successful surgical outcome requires a thorough preoperative clinical evaluation, an understanding of tendon transfer biomechanics, appropriate donor and recipient muscle selection, technical execution, and postoperative rehabilitation. This article reviews the principles, biomechanics, and techniques for commonly performed tendon transfers in patients with upper extremity spasticity. PMID- 30286968 TI - Selective Neurectomy for the Spastic Upper Extremity. AB - Surgery is one element of the rehabilitative care of the spastic upper limb. Different surgical techniques have been advocated to address each of the common deformities and underlying causes, including muscle spasticity, joint contracture, and paralysis. Partial neurectomy of motor nerves has been shown to reduce spasticity in the target muscles. It is effective only for the spastic component of the deformity, which underscores the importance of a preliminary thorough clinical examination. Hyperselective neurectomy, which involves performing a partial division of each motor ramus at its entry point into the target muscle, results in improved selectivity, reliable partial muscle denervation, and durable results. PMID- 30286969 TI - Neurosurgical Management of Spastic Conditions of the Upper Extremity. AB - Spasticity is a hypertonic segmental reflex pathway caused by a central nervous system injury. Spasticity of the upper extremity causes loss of function, joint contracture, pain, and poor cosmesis. Treatment aims to reduce or change the pathophysiology underlying the hyperactive reflex from dorsal sensory rootlets through the intrinsic machinery of the spinal cord to the neuromuscular junction. There are many treatments for upper extremity spasticity including oral medication, physiotherapy, intrathecal baclofen, and lesional or neuromodulatory surgical approaches. Goals of treatment must always be clearly defined, but neurosurgical management is most effective when paired with multidisciplinary therapies and caregiver participation. PMID- 30286970 TI - Management of Spinal Cord Injury-Induced Upper Extremity Spasticity. AB - Spasticity affects more than 80% of patients with spinal cord injury. Neural mechanisms and musculotendinous alterations lead to typical upper extremity features including shoulder adduction/internal rotation, forearm pronation, and elbow, wrist, and finger flexion. Long-standing spasticity may lead to soft tissue and joint contractures and further impairment of upper extremity function. Surgical management involves tendon lengthening, release, and transfer, as well as selective neurotomy, in an effort to reduce spastic muscle hypertonicity, restore balance, prevent further contracture, and improve posture and function. This article summarizes surgical strategies to improve function of the upper extremity in patients with tetraplegia. PMID- 30286971 TI - Rehabilitation Strategies Following Surgical Treatment of Upper Extremity Spasticity. AB - Upper motor neuron injuries that occur in cases such as cerebral palsy, cerebrovascular accidents, and traumatic brain injury often have resulting upper extremity deformity and dysfunction. Multiple surgical options are available to improve upper extremity positioning, and, in some cases, motor control. Postoperative therapeutic management is imperative to assist the patient/caregiver in maximizing potential functional gains. This article provides an overview of postoperative guidelines for commonly performed surgeries to manage upper extremity dysfunction caused by spasticity and discusses acute management as well as therapeutic techniques for functional training and improved motor control. PMID- 30286972 TI - Outcomes After Surgical Treatment of Spastic Upper Extremity Conditions. AB - Surgical interventions for the spastic upper extremity aim to correct the common deformities of elbow flexion, forearm pronation, wrist flexion and ulnar deviation, and thumb-in-palm deformity. One goal is achieving optimal function and improved limb positioning. Aesthetics of the limb have a profound impact on self-esteem and satisfaction. Surgical deformity correction has not reliably been shown to improve sensory function such as stereognosis. Validated outcome measures are used to present outcomes after surgical treatment of the spastic upper extremity as it relates to motor function and limb positioning, sensory function, and self-esteem. PMID- 30286974 TI - Upper Extremity Spasticity. PMID- 30286973 TI - The Future of Upper Extremity Spasticity Management. AB - Surgical management of upper limb spasticity has traditionally tackled the downstream effects at the muscle, tendon, and joint levels. Because this approach does not address the underlying pathologic condition within the nerve, surgical outcomes have been marked by unsatisfactory relapse over time. Future management may focus on reestablishing a normal neuronal impulse pathway to the dysfunctional musculotendinous unit. By severing the faulty gamma-neuronal circuit at the C7 level, spasticity may be reduced. Transfer of the contralateral C7 nerve root to the injured C7 nerve root may open the potential for simultaneously restoring extension and improving reach and grasp functions. PMID- 30286975 TI - Xylo-oligosaccharides enriched yeast protein feed production from reed sawdust. AB - The aim of this study was to convert the cellulose and hemicellulose, in reed sawdust from the pulp mills, into yeast protein and xylo-oligosaccharide, then functionalize xylo-oligosaccharide as yeast feed. Both synchronous saccharification and fermentation and separate hydrolysis and fermentation of cellulase and Candida utilis were investigated to produce protein feed. By optimizing the fermentation conditions, 6.1 g/L of protein with 76.1% (7.1 g/L) xylo-oligosaccharide as the sugar was obtained. The final glucan and xylan utilization efficiencies in reed sawdust were 85.45% and 91.03%, respectively. Xylo-oligosaccharide enriched yeast protein feed from reed sawdust was thus realized by pretreatment, enzymatic hydrolysis and synchronous saccharification and fermentation. PMID- 30286976 TI - Advantages and disadvantages of the prone position in the surgical treatment of supracondylar humerus fractures in children. A literature review. AB - INTRODUCTION: Supracondylar humerus fractures are the most common elbow injuries in children. The widely adopted approach for Gartland III extension type consists of closed reduction and percutaneous pinning; the pin configuration can be lateral or crossed in relationship with the habit of the surgeons. Iatrogenic injury of the ulnar nerve is the most common risk during the insertion of the medial pin. The aim of this study was to analyze advantages and disadvantages of percutaneous pinning with the patient in prone position. MATERIALS AND METHODS: A literature review of the period 2005-2017 was carried out; four medical search engine (Pubmed, Cochrane Library, ISI Web of Science and Scopus) were consulted using the review's filter and the key words "Ulnar nerve AND supracondylar humerus fractures". The total number of patients were analyzed for: ulnar nerve injuries, anesthesiologic management, time of surgery. RESULTS: Twenty-nine papers were read, 23 regarding cross pinning in supine position and 6 in prone position. On one hand, 1529 children were treated with closed reduction and cross pinning in supine position; 69 of these patients (4.5%) suffered from iatrogenic ulnar nerve injury. On the other hand, 579 patients underwent the same treatment in prone position; no ulnar nerve lesions were reported in this group. Only one article compared both groups of children in supine and prone position regarding time of anesthesia which is slightly higher in the prone group. There were no differences between supine and prone positions regarding x-ray exposition, time of surgery, closed reduction manoeuvers, pin positioning, x-ray results, clinical and functional results. DISCUSSION AND CONCLUSIONS: The ulnar nerve in children is hypermobile in the cubital tunnel and tends to dislocate anteriorly over the medial epicondyle, especially when the elbow is in hyperflexion. This may be the reason of the increased risk of nerve injury during the insertion of the medial pin in supine position and, instead, an advantage of the prone position. The insertion of both pins from the lateral side could reduce this complication. Larger studies need to be carried out regarding the reported higher duration of anesthesia in prone position.

AB - In humans, dystrophin mutations cause the X-linked recessive disorder known as Duchenne muscular dystrophy (DMD). These mutations result in skeletal and cardiac muscle damage with mortality increasingly associated with cardiomyopathy. We have identified a novel dystrophin mutation in exon 21 in a line of Australian Labradoodles; affected dogs develop progressive clinical signs including poor weight gain and weight loss, gait abnormalities, exercise intolerance, skeletal muscle atrophy, macroglossa, ptyalism, dysphagia, kyphosis, and a plantigrade stance. Echocardiographic abnormalities include hyperechoic foci in the left ventricular papillary muscles, septal hypokinesis, and decreased left ventricular systolic and diastolic volume and internal diameter. Holter recordings found a Mobitz type II second-degree atrioventricular (AV) block in one affected dog. Analysis of phosphocreatine-to-ATP ratios (PCr/ATP) (obtained via cardiac magnetic resonance imaging and spectroscopy evaluation), found no statistically significant difference in the mean PCr/ATP between groups. Histopathologic skeletal muscle changes included fibrofatty infiltration, myocyte degeneration, necrosis, and regeneration, lymphohistiocytic inflammation, and mineralization; cardiac changes were limited to a focal area of mineralization adjacent to the sinoatrial node in the dog with a second-degree AV block. Due to rapidly progressive clinical signs, a severe phenotype, and potential for cardiac involvement, Australian Labradoodle dystrophinopathy may be a useful model to further study DMD pathogenesis. PMID- 30286979 TI - A comparison of lumbar spine and muscle loading between male and female workers during box transfers. AB - There is a clear relationship between lumbar spine loading and back musculoskeletal disorders in manual materials handling. The incidence of back disorders is greater in women than men, and for similar work demands females are functioning closer to their physiological limit. It is crucial to study loading on the spine musculoskeletal system with actual handlers, including females, to better understand the risk of back disorders. Extrapolation from biomechanical studies conducted on unexperienced subjects (mainly males) might not be applicable to actual female workers. For male workers, expertise changes the lumbar spine flexion, passive spine resistance, and active/passive muscle forces. However, experienced females select similar postures to those of novices when spine loading is critical. This study proposes that the techniques adopted by male experts, male novices, and females (with considerable experience but not categorized as experts) impact their lumbar spine musculoskeletal systems differently. Spinal loads, muscle forces, and passive resistance (muscle and ligamentous spine) were predicted by a multi-joint EMG-assisted optimization musculoskeletal model of the lumbar spine. Expert males flexed their lumbar spine less (avg. 21.9 degrees vs 30.3-31.7 degrees ) and showed decreased passive internal moments (muscle avg. 8.9% vs 15.9-16.0%; spine avg. 4.7% vs 7.1-7.8%) and increased active internal moments (avg. 72.9% vs 62.0-63.9%), thus producing a different impact on their lumbar spine musculoskeletal systems. Experienced females sustained the highest relative spine loads (compression avg. 7.3 N/BW vs 6.2-6.4 N/BW; shear avg. 2.3 N/BW vs 1.7-1.8 N/BW) in addition to passive muscle and ligamentous spine resistance similar to novices. Combined with smaller body size, less strength, and the sequential lifting technique used by females, this could potentially mean greater risk of back injury. Workers should be trained early to limit excessive and repetitive stretching of their lumbar spine passive tissues.

AB - N-methylene phosphonic chitosan (NMPC) is treated with hexyl aldehyde to give an imine, which is easily converted into N-hexyl-N-methylene phosphonic chitosan (HNMPC) under mild conditions. The structure of this new chitosan derivative is characterized by FT- IR, 1H, 13C, 31P, 1H13C-HSQC NMR, SEM and XRD. The influence of reactional parameters on the substitution degree (DS), evidenced that a mol ratio 1.50:1.00 (hexyl aldehyde: free amino groups); a reaction time of 1 h. and 45 degrees C of temperature afford the best DS. HNMPC molecular weight is 12,768.62 Da. It shows good emulsifying properties giving o/w emulsions with high stability in time. Microscopic observation as well as particle size distribution show an unimodal droplet size distribution with low droplet diameters. Preliminary tests lead us to believe that this new polymer has good film forming properties. PMID- 30286981 TI - Integrating 3D-printed PHBV/Calcium sulfate hemihydrate scaffold and chitosan hydrogel for enhanced osteogenic property. AB - We developed the 3D-printed poly(3-hydroxybutyrate-co-3-hydroxyvalerate)/calcium sulfate hemihydrate (PHBV/CaSH) scaffolds by using fused deposition modelling (FDM) technique and then coated the scaffolds with chitosan (CS) acetic acid solution. After drying and neutralization, CS hydrogel was formed on the surface of the scaffolds. The resultant PHBV/CaSH/CS scaffolds could promote the adhesion and proliferation of rat bone marrow stromal cells (rBMSCs) and enhance the osteogenesis of rBMSCs by up-regulating the expression level of osteogenic genes compared to the PHBV and PHBV/CaSH scaffolds. In vivo studies further demonstrated the PHBV/CaSH/CS scaffolds could effectively promote new bone formation. Therefore, integrating 3D-printed PHBV/CaSH scaffold and CS hrydogel represents a novel strategy to promote osteogensis property, showing full potential for bone defects repair. PMID- 30286982 TI - Synthesis of cyclodextrin polymers containing glutamic acid and their use for the synthesis of Ag nanoparticles. AB - Crosslinking and functionalizing agents play crucial roles in the properties/applications of cyclodextrin polymers. Here we report the synthesis of water-insoluble cyclodextrin polymers containing l-glutamic acid. In a first route, beta-cyclodextrin was crosslinked with citric acid and subsequently functionalized with l-glutamic acid, while a second route involved esterification of beta-cyclodextrin with l-glutamic acid, catalyzed by tin octoate. Combined evaluation by FTIR, 13C CP/MAS NMR and elemental analysis indicated that the sample from the first route had the largest fraction of glutamic acid. Sorption tests with methyl orange showed that the cyclodextrin cavities were slightly more available in the polymer obtained through the second route. Samples were employed as reductant and stabilizer for fast and easy synthesis of silver nanoparticles at room temperature. Brief UV irradiation was sufficient for samples produced by the first route.

PMID- 30286984 TI - A mussel-inspired approach towards heparin-immobilized cellulose gel beads for selective removal of low density lipoprotein from whole blood. AB - In this study, we report a mussel-inspired approach to fabricate heparin immobilized cellulose (HeTaCe) gel beads with self-anticoagulative and biocompatible properties which can selectively remove low density lipoprotein (LDL) from whole blood directly. First, a phase inversion technique was applied to prepare cellulose gel beads. Then the as-prepared gel beads were dipped into a mixed solution of heparin and tannic acid in phosphate buffered saline (PBS, pH 8.5) to obtain HeTaCe gel beads. Blood compatibility experiments indicated that the HeTaCe gel beads could suppress complement activation as well as contact activation and prolong the clotting times to the upper detect limits (activated partial thromboplastin time >600 s and thrombin time >180 s) of the automated blood coagulation analyzer. An ideal adsorption capacity of LDL in vitro was achieved by the HeTaCe gel beads with an amount of 79.1 mg/g. Besides, dynamic column adsorption test further demonstrated a selective adsorption of LDL without a significant reduction of high density lipoprotein (HDL) in a simulative hemoperfusion system. It is believed that the HeTaCe gel beads will be quite appealing to future clinical practice aiming at lowering LDL and improving the outcomes of patients with high cardiovascular risk. PMID- 30286985 TI - Preparation, characterization and in vitro evaluation of melatonin-loaded porous starch for enhanced bioavailability. AB - The present work aimed to apply porous starch (PS) as carrier to improve the oral bioavailability of poorly soluble drug melatonin (MLT). The drug loading and encapsulation efficiency of MLT-loaded porous starch (MPS) were optimized. The characteristics of MPS were analyzed using scanning electron microscopy, Brunauer Emmett-Teller surface area, Fourier-transform infrared spectroscopy, x-ray diffraction, differential scanning calorimetry and thermo gravimetric analysis. Most MLT transformed into their amorphous form in the PS pores. MPS showed higher MLT solubility and cumulative release rate compared with raw MLT in SGF and SIF. MPS exhibited a higher inhibition to DCFH-DA-oxidized peroxyl radicals at a lower EC50 than that of the raw MLT. Furthermore, the plasma concentrations of MLT and MPS reached a Cmax of 134.26 and 291.77 ng/mL at 15 and 20 min, respectively. The AUC0-360min of the formulated MPS-treated group was approximately 2.34-fold higher than that of raw MLT. PMID- 30286986 TI - Structural elucidation and immune-enhancing activity of an arabinogalactan from flowers of Carthamus tinctorius L. AB - Previous studies showed that polysaccharides from flowers of Carthamus tinctorius L. had immunomodulating activities. However, their structures were little known. Here, an arabinogalactan, named as HH1-1 with a relative molecular weight of 70.9 kDa, was isolated from flowers of Carthamus tinctorius L. by hot water extraction, followed by purification of a DEAE-Cellulose 32 column and a Sephacryl S-200HR column, subsequently. The structure of HH1-1 was evaluated to have a backbone of 1,6-linked Galp branched at C-3 by side chain of 1,3-linked Galp, with sub-branches attached at its C-3 position. The branches mainly contained 1,5-linked, 1,3,5 linked, terminal arabinose and terminal galactose. Biological activity assays showed that this polysaccharide had immune-enhancing activity by multiple ways, including promoting immune responses by activation of NF-kappaB signaling and increasing TNF-alpha, IL-1beta and iNOS expressions in lymphocytes and macrophages. PMID- 30286987 TI - Protein moiety in oligochitosan modified vector regulates internalization mechanism and gene delivery: Polyplex characterization, intracellular trafficking and transfection. AB - Oligochitosan-modified proteins have gained attention as efficient non-viral vectors for gene delivery. However, little information exists if protein moieties can serve as an important role for internalization and endosome escape ability of the genetic material. To explore this issue, we designed two cationic oligochitosan-modified vectors that consist of different proteins, namely a hydrophobic plant protein (zein) and a hydrophilic animal protein (ovalbumin (OVA)) to deliver pDNA to epithelial cell line CHO-K1 and HEK 293 T. These cationic vectors were systematically characterized by molecular weight, infrared (IR) structural analysis, transmission electron microscopy (TEM) morphology, and surface charge. A remarkable impact of protein moieties was observed on physiochemical properties of the developed vectors. Oligochitosan-modified zein containing hydrophobic protein exhibited high buffering capacity and excellent DNA binding ability compared to the oligochitosan-modified OVA. The data on transfection in the presence of endocytic inhibitors indicated that the caveolae mediated pathway (CvME) played a key role in the internalization of the zein based polyplex. However, the OVA-based polyplex was internalized in CHO-K1 cells via CvME and in HEK 293 T cells via the lipid-mediated pathway. Moreover, oligochitosan-modified zein exhibited lower cytotoxicity, greater lysosomal escape ability, better plasmid stability, and better transfection efficiency than the oligochitosan-modified OVA. This study offers a facile procedure for the synthesis of cationic vectors and elucidates the relationship that exists between protein moieties and transfection activity, thus providing an alternative, non viral platform for the gene delivery. PMID- 30286988 TI - Sulfated O-polysaccharide with anticancer activity from the marine bacterium Poseidonocella sedimentorum KMM 9023T. AB - The sulfated polysaccharides are of study interest due to their high structural diversity and broad spectrum of biological activity including antitumor properties. In this paper, we report on the structural analysis of sulfated O specific polysaccharide (OPS) and in vitro anticancer activity of O-deacylated lipopolysaccharide (DPS) of the marine-derived bacterium Poseidonocella sedimentorum KMM 9023T achieved by a multidisciplinary approach (chemical analysis, NMR, MS, and bioassay). The OPS is shown to include two rare monosaccharide derivatives: 3-deoxy-9-O-methyl-d-glycero-d-galacto-non-2-ulosonic acid (Kdn9Me) and 3-O-acetyl-2-O-sulfate-d-glucuronic acid (D-GlcA2S3Ac). The structure of polysaccharide moiety of a previously unknown carbohydrate containing biopolymer is established: ->4)-alpha-Kdnp9Me-(2->4)-alpha-d GlcpA2S3Ac-(1->. From a biological point of view, we demonstrate that DPS of the P. sedimentorum KMM 9023T has no cytotoxicity and inhibits colony formation of human HT-29, MCF-7 and SK-MEL-5 cells in a dose-dependent manner. The investigated polysaccharide is the second glycan isolated from the bacteria of the genus Poseidonocella: previously we studied the OPS of P. pacifica KMM 9010T (Kokoulin et al., 2017). Both polysaccharides are sulfated and contain rare residues of ulosonic acids. Thus, obtained findings provide a new knowledge about kinds and antitumor properties of sulfated polysaccharides and can be a starting point for further investigations of mechanisms of anticancer action of carbohydrate-containing biopolymers from marine Gram-negative bacteria. PMID- 30286989 TI - Bio-inspired consolidants derived from crystalline nanocellulose for decayed wood. AB - Novel bio-inspired materials derived from crystalline nanocellulose (CNC) have been tested as wood consolidants. A suspension of CNC, produced by acid hydrolysis of cellulose and used as such or mixed with lignin and/or siloxane derivatives (PDMS), was applied on rotted wood samples of Norway spruce. X-Ray diffraction analysis on CNC powder showed high crystallinity index. Dynamic light scattering (DLS) measurement indicated a nearly uniform particle size distribution with an average hydrodynamic diameter for pure CNC smaller than that in the mixtures. Raman and FTIR spectroscopies suggested interactions between lignin, PDMS and CNC components. The storage modulus of wood samples, measured by Dynamic Mechanical Analysis on the same specimen before and after consolidation, confirmed the efficiency of pure CNC, which displayed a considerable improvement of stiffness. A substantial increase of E' was observed particularly for most decayed classes. These results suggest a closer interaction between nanocellulose and decayed wood. PMID- 30286990 TI - Accurate molar masses of cellulose for the determination of degradation rates in complex paper samples. AB - Complex cellulosic samples are often difficult to analyse with size-exclusion chromatography. The strong molecular associations of hemicelluloses and lignin with cellulose produce multimodal molar mass distributions (MMD) that are difficult to interpret. More reliable ways of calculating the molar masses of cellulose are thus necessary. This is particularly relevant when studying the kinetics of paper degradation, as the number average molar mass is the most precise indicator. In this study various data handling methods based on the deconvolution of bimodal and multimodal MMDs of complex cellulosic samples after SEC-MALS-DRI analysis are examined in order to propose more accurate paper degradation rates. Two deconvolution methods, which do or do not rely on polymer calibration curves were developed and were applied to several kraft and groundwood pulp papers unaged and hygrothermally aged. The deconvolution methods are discussed and evaluated in light of calculated cellulose activation energies, degradation rates and paper usable lifetime predictions. PMID- 30286991 TI - Development and characterization of sugar palm nanocrystalline cellulose reinforced sugar palm starch bionanocomposites. AB - Sugar palm fibre (SPF) was treated with NaClO2, bleached with NaOH and subsequently hydrolyzed with acid to obtain sugar palm nanocrystalline cellulose (SPNCCs). Bionanocomposites in the form of films were prepared by mixing sugar palm starch (SPS) and sorbitol/glycerol with different nanofiller SPNCCs compositions (0-1.0 wt%) using solution casting method. The resulting fibres and nanocomposites were characterized in terms of morphology (FESEM and TEM), footprint, crystallinity (XRD), light transmittance, biodegradability, physical, water barrier, thermal (TGA, DSC and DMA) and mechanical properties. The length (L), diameter (D) and L/D values of the SPNCCs were 130 +/- 30.23, 8.5 +/- 1.82 nm, and 15.3, respectively. The SPS/SPNCCs nanocomposite films exhibited higher crystallinity, tensile strength, Young's modulus, thermal and water-resistance compared to the neat SPS film. The results showed that the tensile strength and moduli of the bionanocomposites increased after being reinforced with SPNCCs and the optimum nanofiller content was 0.5%.

AB - Chitosan is widely used in the preparation of organic-inorganic composite materials, such as n-HAp/CS composites, which find application for bone regeneration. The methods for their preparation are various, and usually based on the preparation of intermediate n-HAp/CS dispersions, which can greatly influence the final properties of the resulting composites since it is expected that homogenous and stable dispersions lead to composite materials with improved final properties. This work hypothesizes that, additionally to process parameters such as pH, n-HAp/CS weight ratio, mixing conditions and the presence of salts, chitosan itself has a high impact on dispersions stability. Thus, the importance of properly control the preparation of the n-HAp/CS intermediate dispersions is highlighted by doing a systematic study where relevant processing parameters were studied at lab scale using ultrasonication, alone or in the presence of chitosan, namely on particle size and zeta potential. Furthermore, and based on the best laboratorial conditions, the production of n-HAp/CS nanocomposite dispersions in continuous mode was attempted through NETmix(r) technology, an innovative static mixer and reactor developed at the Associate Laboratory LSRE-LCM of the Faculty of Engineering of the University of Porto (FEUP).

AB - The aim of this study was to investigate the antioxidant, mechanical and physical properties of a new film-based polymeric blend of hydrocolloids obtained from the aqueous extraction of chia seeds (source antioxidants) and apple pectin. The individual matrices films were brittle and rigid with poor mechanical properties. The blends formulations contributed to improved mechanical properties regarding workability and resistance. The antioxidant results showed the potential hydrocolloid from chia seeds as natural source of antioxidant in these polymeric films. The formulation 3 (14(hydrocolloid):41(pectin):25(glycerol):20(glutaraldehyde) displayed well thermal, mechanical, morphological and antioxidant properties, suggesting their great potential for food packaging. PMID- 30286994 TI - A holistic approach to unravelling chondroitin sulfation: Correlations between surface charge, structure and binding to growth factors. AB - Chondroitin sulfate (CS) is a relevant family of polysaccharides that participates in a large variety of biological events that are related to neural processes by regulating various growth factors through the pattern and degree of sulfation of the polysaccharide. However, their own complexity makes their optimization for biomedical applications a difficult undertaking. Thus, a different perspective has to be taken. Herein, we show that the particular sulfate distribution within the disaccharide repeating-unit plays a key role in the binding of growth factors (GFs). In particular, this disposition modulates the surface charge of the helical structure that, interestingly, has a significant influence on the binding capacity of CSs with several GFs. This fact should be carefully considered in the design of new ligands with improved activity as GFs ligands. PMID- 30286995 TI - Enhanced antibacterial profile of nanoparticle impregnated cellulose foam filter paper for drinking water filtration. AB - Filtration is a promising water treatment method to purify drinking water. To develop highly efficient drinking water filter paper, water-resistant cellulose foam paper with a high wet strength property was fabricated using diverse metal oxide (e.g., copper oxide (CuO), zinc oxide (ZnO), and silver oxide (Ag2O)) nanoparticles. These nanoparticles were synthesized using the hydrothermal reaction method. Their morphological structures were studied using a field emission scanning electron microscope (FESEM). The presence of coated nanoparticles on the cellulose foam filter was verified by energy dispersive X ray spectroscopy (EDX) methods. The antibacterial performance of different types of modified cellulose foam filters was studied against E. coli, P. aeruginosa, B. subtilis, and B. cereus strains using the zone of inhibition test. The antibacterial profile of the cellulose foam filter impregnated with Ag2O nanoparticles, when tested against different types of bacteria, exhibited higher antibacterial activity than the cellulose foam filter impregnated with ZnO and CuO nanoparticles. PMID- 30286996 TI - Synthesis of a new superabsorbent copolymer based on acrylic acid grafted onto carboxymethyl tragacanth. AB - In this research, a new superabsorbent copolymer was synthesized based on the tragacanth gum (TG) via graft polymerization of the acrylic acid onto the carboxymethyl tragacanth (CMT) in the aqueous solution. For this purpose firstly, the carboxymethyl tragacanth was synthesized by reaction of the tragacanth gum and the monochlroroacetic acid in basic conditions. Then the acrylic acid was grafted on the carboxymethyl tragacanth via free radical polymerization. The characterization of the products was carried out by FT-IR, TGA, and SEM analyses. The effects of reaction conditions such as different values of the initiator, monomer and crosslinking agent on water absorbency were investigated. Furthermore, the swelling behavior of the synthesized polymer was evaluated in normal saline, tap water, distilled water, at different pHs and in various degrees of neutralization of the acrylic acid. Finally, by studying the obtained results, optimum conditions for the copolymer with the highest swelling ratio were obtained. PMID- 30286997 TI - Structural characterization of the surface-associated heteropolysaccharide of Lactobacillus plantarum TMW 1.1478 and genetic analysis of its putative biosynthesis cluster. AB - Microbial exopolysaccharides (EPS) like xanthan are widely exploited as natural biopolymers in diverse industrial sectors. In foods, in-situ EPS formation by starter cultures allows the manufacturing of "clean labeled" products with improved textural and nutritional properties. We performed structural analyses of the cell surface-associated EPS produced by Lactobacillus plantarum TMW 1.1478, which is a promising starter culture for fermented foods. Chromatographic analyses and NMR experiments suggested an acetylated heptameric repeating unit comprised of glucose, rhamnose and galactose as major components, whereas analysis of the macromolecular HePS structure suggested an apparent molecular mass of Mr ~2 * 106 and a root mean square (RMS) radius of ca. 60 nm. Genetic analyses enabled the identification of the respective EPS biosynthesis cluster, and its modular organization supports the chemically identified, novel EPS structure. The obtained results broaden the understanding of complex EPS formation from activated sugar nucleotides by Lactobacillus plantarum. PMID- 30286998 TI - Cytocompatible chitosan based multi-network hydrogels with antimicrobial, cell anti-adhesive and mechanical properties. AB - Hydrogel with good mechanical and biological properties has great potential and promise for biomedical applications. Here we fabricated a series of novel cytocompatible chitosan (CS) based double-network (DN) and triple-network (TN) hydrogels by physically-chemically crosslinking methods. Natural polysaccharide CS with abundant resources was chosen as the first network due to its good antimicrobial activity, biocompatibility and easy cross-linking reaction. Zwitterionic sulfopropylbetaine (PDMAPS) was chosen as the second network due its good biocompatibility, antimicrobial and antifouling properties. And nonionic poly(2-hydroxyethyl acrylate) (PHEA) was chosen as the final network due to its good biocompatibility, excellent nonfouling and mechanical properties. Cross section SEM images showed that both CS/PHEA (DN1, the molar ratio of glutaraldehyde to structural unit of CS is 0.2/3.0) and CS/PDMAPS/PHEA (TN1, the molar ratio of glutaraldehyde to structural unit of CS is 0.2/3.0) hydrogels exhibited a smooth and uniformly dispersed porous microstructures with pore size distribution in the range of 20~100 MUm. The largest compressive stress and tensile stress of DN1 hydrogels reached 84.7 MPa and 292 kPa, respectively, and largest compressive stress and tensile stress of TN1 hydrogels could reach 81.9 MPa and 384 kPa, respectively. Moreover, the value of failure strain for TN1 gels reached 1020%. Besides excellent mechanical properties, DN1 and TN1 gels exhibited good antimicrobial, cytocompatible and antifouling properties due to introduction of antimicrobial chitosan, cell anti-adhesive PDMAPS and PHEA. The combination of the excellent mechanical and biological properties of multiple network hydrogels can provide a potential pathway to develop biomedical hydrogels as promising bioapplications in wound dressing and other biomedical applications. PMID- 30286999 TI - 6-Maleimidohexanoic acid-grafted chitosan: A new generation mucoadhesive polymer. AB - This study aims to synthesize and evaluate a new generation mucoadhesive polymer, 6-maleimidohexanoic acid-grafted chitosan; MHA-CS, for transmucosal drug delivery compared with a well-known mucoadhesive polymer, Cys-CS. The successful synthesis was confirmed by nuclear magnetic resonance (NMR) spectroscopy and Fourier transform infrared (FT-IR) spectroscopy. Gel permeation chromatography (GPC) was used to determine the molecular weight of the synthesized polymer. The quantity of maleimide on the polymer chain as well as the mucoadhesive properties and biocompatibility of the synthesized polymers were also assessed. The results revealed that the synthesized MHA-CS demonstrated excellent mucoadhesive properties which is superior to CS and Cys-CS. The maleimide content bound to synthesized polymer was 466 MUmol per gram of the polymer. The cytotoxicity test assured the low toxicity of the synthesized polymer on the normal human gingival fibroblast cells. These data support the potential of MHA-CS as a novel material for developing mucoadhesive drug delivery system with enhanced mucoadhesive properties. PMID- 30287000 TI - Plantain flours as potential raw materials for the development of gluten-free functional foods. AB - Plantain flour (Musa ssp., group AAB, sub-group clone Harton) was modified by acetylation, carboxymethylation, methylation, oxidation and phosphation, in order to determine which of these modifications produce a material with potential for the development of gluten-free products with improved nutritional properties. The structural, rheological and nutritional properties of the modified flours were investigated. The phosphated plantain flour, cross-linked with sodium trimetaphosphate (STMP), had a lower in vitro digestibility rate associated with resistant starch (RS) types RS2, RS4 and RS5. This latter was confirmed by the formation of the amylose-lipid complex as determined by XRD. All the flours tested had a C-type structure with the exception of the methylated plantain flour which produced a large quantity of reaction by-product (BaSO4). The phosphated plantain flour represents a raw material with great potential for the development of gluten-free food (bread and cookie) with functional properties, i.e. health benefits. PMID- 30287001 TI - Periodate oxidation of xylan-based hemicelluloses and its effect on their thermal properties. AB - Hemicellulose from pulp mill process water and crop residuals from food production often end up in waste streams or burnt for energy contribution. These waste products contain valuable biopolymers but lack many attributes needed for use in applications such as food and medical or consumer products. This study reports on an investigation of the periodate oxidation of hardwood xylan and arabinoxylan (AX) from wheat bran to produce materials with new functionalities. The study explores how to control the oxidation degree and describes structural differences between the two xylan-based polymers. For the xylan samples, the oxidation resulted in a lowering of the glass transition temperature (Tg), indicating a more flexible chain due to ring-opening of the xylan anhydro-sugar units. For the AX samples, the arabinose side-groups were instead oxidized, hindering oxidation on part of the xylose units, which resulted in a crosslinked network with an unchanged Tg but reduced intrinsic viscosity. PMID- 30287002 TI - In vitro and in vivo evaluation of pirfenidone loaded acrylamide grafted pullulan poly(vinyl alcohol) interpenetrating polymer networks. AB - The aim of present study was to develop controlled release formulation of pirfenidone using acrylamide grafted pullulan. Interpenetrating polymer network (IPN) microspheres were prepared using acrylamide grafted pullulan and PVA utilizing glutaraldehyde assisted water-in-oil emulsion crosslinking method. IPN microspheres were characterized by FTIR, solid state 13C NMR and XRD spectroscopy. In vitro enzymatic degradation study showed 34.30% degradation after 24 h with degradation rate constant of 0.0088 min-1. In vitro biocompatibility test showed no changes in cellular morphology and cell adherence to microspheres, indicating its biocompatible nature. The release exponent value of all formulations was less than 0.45, indicating the release mechanism to be Fickian diffusion. Finally, in vivo pharmacokinetic study showed longer Tmax (1.16 h) and greater AUC value (10037.76 ng h/mL,) as compared to Pirfenex(r) (Tmax = 0.5 h; AUC = 4310.45 ng h/mL,). The results indicated that the prepared formulation could successfully control the drug release for prolonged time period. PMID- 30287003 TI - Effect of chemical modification with citric acid on the physicochemical properties and resistant starch formation in different starches. AB - Potato, cassava, sweet potato, banana and lentil starches were modified with citric acid (CA) with the main objective of enhancing the resistant starch (RS) and slowly digestible starch (SDS) fractions and to compare starches of diverse botanical origins. The percentage CA substitution of modified starches ranged from 3.84 to 15.06 and showed similar type of XRD patterns, but with variation in intensity and percentage crystallinity. The peaks around 1705 cm-1 and 1150 cm-1 in FT-IR spectra of modified starches confirmed the presence of CA group. Scanning electron microscopy confirmed that there were no noticeable changes in granular structure and morphology. No peaks could be observed in RVA pasting profiles of modified starches, confirming cross-linking reaction. The SDS and RS were significantly higher in modified starches of all origins and consequently there was a lower estimated glyceamic index (EGI). Modified starches were associated with lower setback viscosity indicating their lower temperature stability. PMID- 30287004 TI - Study of the behavior of biodegradable starch/polyvinyl alcohol/rosin blends. AB - Biodegradable potato starch/PVA samples containing different concentrations of rosin were prepared by melt-mixing in order to study the enhancement of the properties of native starch films. Glycerol and polyvinyl alcohol (PVA) are commonly used as plasticizers of starch. Their relatively low molecular weight (compared with starch) contributes to a good processability. Rosin is a renewable product whose incorporation in the starch/PVA matrix induces processing aid and reinforcing effects. Its relatively high molecular weight might prevent its migration to the surface of the final product. Water content, solubility in water, mechanical properties, microstructure and dynamic mechanical analysis of the samples were studied. The addition of 8% rosin to starch/PVA blends led to tensile strength values higher than 10 MPa and elongation at break values close to 2000%, values comparable to those offered by conventional polymers used in food packaging, for example LDPE. Furthermore, starch compounds have low cost and high biodegradability. PMID- 30287005 TI - Efficient removal of Pb(II), Cr(VI) and organic dyes by polydopamine modified chitosan aerogels. AB - Chitosan is highly suitable for removing metal ions and dyes from water; however, the sorption performance, stability and recycling are still critical issues in practical applications. Herein, polydopamine-modified-chitosan (CS-PDA) aerogels were synthesized through dopamine self-polymerization and glutaraldehyde cross linking reactions to enhance the adsorption capacity and acid resistance of chitosan. The self-polymerization of dopamine and gelation of chitosan were accomplished simultaneously, simplifying the synthesis process of CS-PDA aerogels, which is meaningful for the popularization and industrial application of adsorbent. CS-PDA exhibited superior adsorption performances in the removal of Cr(VI), Pb(II) and organic dyes. Adsorption isotherms and kinetic data were well fitted by Langmuir and pseudo-second-order kinetic models. The maximum adsorption capacities of CS-PDA for Cr(VI) and Pb(II) were 374.4 and 441.2 mg g-1, respectively. After eight cycles, adsorption capacity of CS-PDA showed no obvious decline. These superiorities make CS-PDA a promising multifunctional adsorbent for the purification of metal ions and dyes.

AB - Designing scaffolds capable of mimicking the 3D structure of the extracellular matrix (ECM) and deliver signaling factors to affect and control the cell response favorably, is of high importance in the field of tissue engineering. As polymeric nanoparticles are effective vehicles for delivering growth factors, this study aimed to fabricate and characterize a nanocomposite scaffold based on chitosan and gelatin, incorporated with chitosan nanoparticles loaded with basic fibroblast growth factor (bFGF) and bovine serum albumin (BSA). Nanoparticles, prepared by the ionic gelation method, were loaded with BSA-bFGF and introduced into chitosan-gelatin scaffolds to enhance their biological properties. Structural characterizations and biological assays showed that nanoparticles significantly affected the physical properties of the scaffold and could provide a sustained release of growth factor to enhance the proliferation of fibroblast cells significantly. These results are promising for improving the properties of chitosan-gelatin scaffolds in tissue engineering applications, especially where the delivery of angiogenic growth factor such as bFGF is needed.

AB - pH-Responsive drug vehicles targeting the specific extracellular pH of tumors have served as potent tools to overcome the limitation (e.g., low tumor seletivity) in antitumor drug delivery system. Here, we describe the advantage of pH-responsive extracellular vesicles (HDEA@EVs) containing the hyaluronic acid grafted with 3-(diethylamino)propylamine (HDEA) and a model antitumor drug, doxorubicin (DOX). We demonstrated their physicochemical characteristics through in vitro cell endocytosis, in vitro tumor cell toxicity, in vivo biodistribution, and in vivo tumor regression efficacy experiments. Because the HDEA@EVs efficiently responded to extracellular tumor pH (pH 6.5) and actively bound to CD44 receptors on HCT-116 tumor cells, the EVs selectively inhibited CD44+ tumor cell growth in vitro, and CD44+ tumor development in vivo. From these results, we conclude that HDEA@EVs can help in designing effective strategies for pharmacologic intervention in tumor therapy.

AB - The present work demonstrates functionalized chitosan as an ecofriendly substitute to the conventional costly substrates and monomers for simultaneous surface imprinting of salicylic acid (SA) and cadmium (Cd). Dual surface imprinted acrylamide functionalized chitosan based polymer (AGDMIP), with higher numbers of imprinted sites for SA and Cd was synthesized using acrylamide grafted chitosan, epichlorohydrin as crosslinker, Cd as template and 4 hydroxy benzoic acid (4HBA) as mimic template (supported by computational modeling). FTIR, SEM, XRD, BET surface area and TEM analysis confirmed successful preparation, mesoporous nature and surface imprinting of AGDMIP. The adsorption data could be fitted into Langmuir isotherm model with the maximum adsorption capacity of 45.77 mg g-1 (SA) and 53.42 mg g-1 (Cd). Temkin and Intraparticle diffusion models confirmed the chemical nature and presence of imprint sites within AGDMIP respectively. AGDMIP could be reused for six cycles and exhibited good removal efficiency in real samples.

AB - The catalytic activity of commercially available chitosan has been investigated for the Knoevenagel reaction of ethylacetoacetate (EAA)/dimethylmalonate (DMM) with arylaldehydes. Among all the screened solvents, Chitosan performed the best in water as reaction medium. Substrate scope was evaluated by using various arylaldehydes and it was observed that presence of electron donating groups on aldehydes reduce the yields, while electron-withdrawing groups increase the yields. In case of the reaction of 4-bromobenzaldeyde with EAA, the lower yield of the corresponding product 14 was obtained due to the high stability of imine intermediate formed and this postulate was proved by experiments as well as theoretical calculations. In case of EAA, the E/Z stereochemistry of the corresponding products was assigned based on NOESY experiment. PMID- 30287009 TI - Chitosan functionalized poly (epsilon-caprolactone) nanoparticles for amphotericin B delivery. AB - Amphotericin B (AmB) is a broad-spectrum antifungal drug used in the treatment of fungal invasive infections. However, its clinical use has been limited due to its side effects and toxicity, especially the nephrotoxicity. Furthermore, AmB presents low aqueous solubility, low permeability over the membranes and poor stability in the gastric environment, which makes it unavailable to be administered by the oral route. In this study, chitosan-coated poly (epsilon caprolactone) nanoparticles were developed to provide the oral delivery of AmB and reduce its toxicity. Nanoparticles were obtained by nanoprecipitation and parameters as particle size, polydispersity index (PDI), zeta potential, morphology, in vitro AmB release (in physiological pH and simulated gastrointestinal fluids), state of molecular aggregation, cytotoxicity over erythrocytes and Vero cells line and in vitro antifungal activity were fully investigated. Nanoparticles presented mean size of 318 +/- 35 nm, PDI of 0.24 +/- 0.02, zeta potential of +36.2 +/- 1.8 mV due to chitosan-coating, and 69% of AmB encapsulation. The kinetic release profile of AmB from nanoparticles was of second order and diffusion-governed in pH 7.4. The release in the gastrointestinal simulated fluids showed that the chitosan-coated PCL nanoparticles presented good stability during the time evaluated. AmB was released from nanoparticles in a state of low molecular aggregation. Cytotoxicity over erythrocytes and Vero cells line revealed that nanoencapsulation significantly reduced the AmB-related cytotoxicity (p < 0.05) compared to the free drug. In the antifungal activity against Candida parapsilosis strain, the MIC of AmB-loaded nanoparticles was 5-fold higher than free AmB, but the strain was susceptible to nanostructured AmB. Chitosan-functionalized PCL are potential carriers for the oral AmB delivery, reducing its cytotoxicity and maintaining its activity.

AB - Exhaustion dyeing of cotton means a significant proportion of dyestuff is not fixed onto the material and is drained out when the dyebath is emptied. This waste presents issues for dye houses in terms of remediating water quality and the loss of expensive dye chemicals. Work to improve the dyeing ability of cotton has been limited to modifying cotton's cellulose structure by, notionally, environmentally hazardous treatments, e.g., concentrated caustic soda. Here we use a buffered, aqueous glycine treatment to improve the dyeing ability of cotton. The treated cotton showed improved dye absorption compared with control samples. An investigation of the structure of the treated cotton using Fourier Transform Infrared spectroscopy (FTIR) and 13C solid-state nuclear magnetic resonance (NMR) showed there was no appreciable change in crystallinity. However, there were changes in the chemical structure of the glycine-cellulose complex that were related to the pH of the buffered glycine treatment. PMID- 30287012 TI - Starch/graphene hydrogels via click chemistry with relevant electrical and antibacterial properties. AB - Starch-based hydrogels were performed by Diels-Alder cross-linking reactions between furan-modified starch and a water soluble bismaleimide, with improving conducting properties by using graphene layers as active nanofillers. The characterization results demonstrated that the Diels-Alder reaction and the corresponding conditions for the hydrogel formation were appropriate. The effect of increasing the furan/maleimide ratio on the architecture of the hydrogels and on the morphological, rheological and swelling properties were thoroughly evaluated. Effective network structure was obtained by increasing the cross linker content leading to decreasing pore size and increasing storage modulus value of the final material. It was shown that the swelling behavior of hydrogels was mainly governed by the hydrophilic character of bismaleimide. Graphene nanosheets were added for the synthesis of nanocomposite hydrogel and it was characterized in terms of rheological properties, electrical conductivity and antimicrobial activity. The nanocomposite hydrogel presented enhanced mechanical performance, antimicrobial activity and increased conductivity values, up to a decade, indicating that conductive and active hydrogels could be satisfactory obtained, for a large range of potential applications such as biomed. PMID- 30287013 TI - Sulfonated and sulfated chitosan derivatives for biomedical applications: A review. AB - From 20th century, chitosan, a natural polysaccharide, has received much attention for use in biomedical applications thanks to its remarkable properties, such as biodegradability, biocompatibility, hemostasis and antibacterial activity. Over the last decades, many researchers have attempted to generate new chitosan derivatives-based biomaterials though chemical modifications, especially through sulfonation or sulfation reactions in order to tailor the physicochemical and biochemical properties. Due to the presence of residual amino groups, the generated polyampholytic derivatives are characterized by convenient biological properties, such as antioxidation, antiviral activity, anticoagulation and bone regeneration, expanding their application scope. This paper provides an overview of the strategies used to chemically modify chitosan by introduction of sulfonate groups on chitosan backbone, focusing on various sulfonating or sulfating agents used and substitution regioselectivity, and highlights their applications in biomedical field. PMID- 30287014 TI - Preparation, characterization and functional evaluation of chitosan-based films with zein coatings produced by cold plasma. AB - Chitosan-based films with zein coatings were prepared in order to modify the drug release properties. The adhesion of zein layers to the films was ensured via a cold plasma treatment. Using ciprofloxacin hydrochloride as model, the effect of cold plasma on the functional properties and structures was evaluated. The results suggest that the encapsulation efficiency, chemical composition and crystal type of ciprofloxacin hydrochloride in chitosan/drug films were not altered by cold plasma treatment, while the wettability and surface free energy displayed a notable increase. After being coated with zein, the chitosan interacted with the zein through hydrogen bonding and electrostatic interactions. The burst release phenomenon of the chitosan/drug films was prevented by the zein coating. Furthermore, the plasma treatment provided the coated film with a slower release rate within 24 h, from 72.8% to 49.3%. The enhanced coating thickness and the more compact interface structure were responsible for this improvement. PMID- 30287015 TI - Modification of chitin structure with tailored ionic liquids. AB - Chitin, poly N-acetylglucosamine, has a great potential for use on an industrial scale as an enzyme carrier but it has an unfavorable particle structure that can be modified using ionic liquids (ILs). Several ionic liquids were investigated that have the same substituents on the ring (methyl- and propyl-) but differed in the type of cationic ring (pyrrolidinium, piperidinium, and piperazinium). Organic acid ions (acetic and lactic) were used as counter ions. 1-ethyl-3-methyl imidazolium acetate and 1-ethyl-3-methyl-imidazolium lactate were used as a reference. The results confirm that the chitin particle structure or size, or both, simultaneously changes if chitin is dissolved in an IL and then precipitated. Organic acid anions and short substituents on the cationic ring of ILs influenced particle modification substantially, whereas the type of ring played a minor role. Additionally, the ionic liquids [MPpyrr][OAc], [MPpip][OAc] and [DMPpz][OAc] could be reused up to at least 4 times without losing their ability to dissolve chitin.

AB - Silanized hydroxypropyl methylcellulose based hydrogels were developed for cartilage and intervertebral disc tissue engineering. Herein, study of dynamics of confined water showed two different populations, identified as hydration and bulk-like water. The diffusion coefficient showed that bulk-like water diffuses over distances ~10 MUm without being affected by the hydrogel matrix. Addition of silica nanofibers leads to improved mechanical properties and enhanced diffusion coefficient. Good diffusion within hydrogels is essential for the application. PMID- 30287017 TI - A novel, green, low-cost chitosan-starch hydrogel as potential delivery system for plant growth-promoting bacteria. AB - The study examines the use of macrobeads for the controlled-release of bacteria. Macrobeads were prepared by an easy dripping-technique using 20/80 wt/wt chitosan starch blends and sodium tripolyphosphate as cross-linking agent. The resulting polymeric matrix was examined by SEM, XRD, TGA, and solid-RMN. The swelling equilibrium, thermal behaviour, crystallinity, and size of macrobeads were affected by the autoclave-sterilization. The diameter of the sterilized xerogel was c.a. 1.6 mm. The results suggested that ionotropic-gelation and neutralization were the mechanisms underlying hydrogel formation. Plant growth promoting bacteria (PGPB) were loaded into macrobeads separately or co inoculated. Bacteria loaded macrobeads were dried and stored. Bacteria survived at least 12 months in orders of 109 CFU of A. brasilense/g and 108 CFU of P. fluorescens/g. Bacterial release in sterile saline solution tended to a super Case-II transport mechanism. Polymeric-matrix release efficiently both PGPB in natural soils, which uncovers their potential for the formulation of novel and improved biofertilizers. PMID- 30287018 TI - Nanocellulose and chitosan based films as low cost, green piezoelectric materials. AB - Nanocellulose and chitosan have recently started to get attention as environmentally friendly piezoelectric materials for sensor and energy harvesting applications. Conversely, current commercially available flexible piezoelectric films made of for example polyvinylidene difluoride (PVDF) are relatively expensive and made from non-renewable materials. We measured the piezoelectric responses (2-8 pC/N) for solvent casted films based on nanocellulose, microcrystalline chitosan and their blends. In addition, the tensile properties of the piezoelectric films were characterized to find out if chitosan could be used to enhance the flexibility of the brittle nanocellulose films. Based on the results, plain chitosan is an interesting piezoelectric material itself. In addition, blending nanocellulose and chitosan could be a potential method for tailoring the properties of solvent casted low cost, green piezoelectric films. PMID- 30287019 TI - Natural polymer konjac glucomannan mediated assembly of graphene oxide as versatile sponges for water pollution control. AB - Three-dimensional network structure of konjac glucomannan/graphene oxide (KGM/GO) sponges was successfully prepared by ice template method. The KGM/GO sponges was rich in functional groups, negatively charged under pH 2 to 10. Batch adsorption experiment was conducted to investigate the adsorption performance of the as prepared KGM/GO sponges for organic dye (malachite green (MG)) and radionuclide (uranium U(VI)). The results showed that the maximum adsorption capacities of KGM/GO sponges were 266.97, 189.96 mg/g for U(VI) and MG, respectively. Moreover, the KGM/GO sponges exhibited an excellent selectivity for capturing U(VI) in multi-ion system. The adsorption process was fitted better to pseudo-second order model, while adsorption isotherms for these pollutants were well matched up to Langmuir models. In addition, KGM/GO sponges can be easily separated from the aqueous solution and could be effectively reused for 5 times without obvious loss in adsorption performance. The advantages of eco-friendliness, low cost, simple preparation process, controllable shape and size, as well as high adsorption capacities for MG and U(VI), suggested that KGM/GO sponges promising in water pollution control.

AB - In this study, liquid hot water (LHW) and chemical (H2SO4, NaOH, CaO) pretreatments were performed in Saccharum species including sugarcane bagasse. In comparison, the LHW and CaO pretreatments significantly enhanced biomass enzymatic hydrolysis, leading to much high bioethanol yield obtained at 19% (% dry matter) with an almost complete hexoses-ethanol conversion in the desirable So5 bagasse sample. Despite the LHW and CaO are distinctive for extracting hemicellulose and lignin, both pretreatments largely reduced cellulose degree of polymerization for enhanced lignocellulose enzymatic saccharification. Further chemical analysis indicated that the pretreated So5 sample had much lower cellulose crystalline index, hemicellulosic Xyl/Ara and lignin S/H ratio than those of other biomass samples, which explained that the So5 had the highest bioethanol yield among Saccharum species. Therefore, a mechanism model was proposed to elucidate how mild pretreatments could enhance biomass enzymatic saccharification for a high bioethanol production in the desirable sugarcane bagasse.

AB - Natural biopolymers are better adsorbents due to better functionality, surface area, bio-compatibility and ease of procurement. The gum arabic in natural biopolymer derived from Acacia Arabic species. In the present work a novel nanohydrogel of gum arabic with acrylamide has been fabricated using microwave synthesis for adsorption of noxious crystal violet dye from aqueous medium. The prepared gum arabic-cl-poly(acrylamide) nanohydrogel (GA-cl-poly(AAm)) NHG was characterized by numerous techniques including SEM, XRD, TEM and FTIR. The GA-cl poly(AAm) NHG showed promising adsorption ability for crystal violet dye. The effect of various adsorption factors such as concentration of GA-cl-poly(AAm) NHG and crystal violet, pH, temperature and time has been studied and reported. For understanding the adsorption mechanism three models Langmuir, Freundlich and Temkin were applied to adsorption data The kinetics and thermodynamics of adsorption were also investigated The adsorption capacity of crystal violet onto GA-cl-poly(AAm) NHG according to Langmuir model is found to be 90.90 mg/g. PMID- 30287022 TI - Crosslinking of agar by diisocyanates. AB - In the present study, crosslinking of agar using diisocyanate (DI) was demonstrated to limit the high water absorption property of agar. In addition, the efficacy of aromatic diisocyanate, DDI (4, 4 diphenyl diisocyanate) and aliphatic diisocyanate, HDI (1, 6 hexamethylene diisocyanate) on crosslinked agar properties was compared. The water uptake was successfully reduced by crosslinking and its minimum values observed for DDI and HDI crosslinked agar was 33.6% and 43.6%, respectively in comparison to agar (206%). The maximum tensile strength was observed for DDI crosslinked agar (45.3 MPa) which was higher than HDI crosslinked agar (30.6 MPa) and agar (31.7 MPa). The aromatic diisocyanates crosslinked agar showed better thermal resistance at higher temperature. It was observed that aromatic diisocyanate crosslinked agar more effectively than the aliphatic diisocyanate due to the higher reactivity. The crosslinked agar samples were hemocompatible and show non-toxic nature for cell proliferation. PMID- 30287023 TI - Chemical characteristics, antioxidant capacities and hepatoprotection of polysaccharides from pomegranate peel. AB - This proposed work aimed to investigate the chemical characteristic, antioxidant capacities and hepatoprotection effect of pomegranate peel polysaccharides (PPP) on CCl4-induced oxidative damage in mice. PPP was identified as the acidic heteropolysaccharides by HPLC methods. In vitro test showed that PPP had excellent reducing power and scavenging effects against free radicals. Administration of PPP (50, 100 and 200 mg/kg.bw) in mice before the injection of CCl4 could observably antagonize the increased serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and hepatic malonaldehyde level in CCl4-induced mice, especially administrated with 200 mg/kg.bw of PPP. Hepatic enzymatic activities of total superoxide dismutase, glutathione peroxidase, catalase and non-enzymatic activity of glutathione were markedly increased at high dosage of PPP, respectively. In addition, histopathological observation of liver further proved these biochemical characteristics. Therefore, it can be concluded that PPP exhibits strong protective effects against CCl4-induced liver injury in mice.

AB - The grain development of normal maize in Southern China is affected by decreases in sunlight intensity over the period of mid-June to mid-July. This study examined the starch structure and function of four normal maize varieties that had been exposed to weak-light stress (50% light deprivation; ambient light conditions served as the control) during grain filling. In all tested varieties, light deprivation decreased the contents of starch and amylose, and increased the size of starch granules and the proportion of long chains in amylopectin. Shading increased the relative crystallinity and ordered-to-amorphous ratio of starch. Shading decreased the gelatinization and retrogradation enthalpies and pasting and gelatinization temperatures of starches but increased retrogradation percentage and pasting viscosities. In conclusion, weak-light stress during grain filling increases starch viscosity and retrogradation tendency and decreases thermal stability by reducing amylose content, increasing the sizes of starch granules and the proportion of long chains in amylopectin, and improving the relative crystallinity. PMID- 30287025 TI - Modified cellulose by polyethyleneimine and ethylenediamine with induced Cu(II) and Pb(II) adsorption potentialities. AB - In order to synthesize adsorbent that can effectively absorb heavy metals in a simple and economical way, this study described the fabrication of adsorbents based on cellulose acetate (CA). CA modified first by polyethyleneimine grafting (CAP) and then by ethylenediamine (CAPE) for enhancing Cu(II) and Pb(II) removal from water. The physico-chemical properties of the modified celluloses were analyzed. It was found that the adsorption functional groups (amino groups) were successfully grafted on cellulose and CAP converted from semi-crystalline to cellulose II after enhancement of ethylenediamine (EDA). Adsorption isotherm results showed that the Cu(II) and Pb(II) removal efficiency by CAPE was significantly higher than that by CAP, and CAP showed a higher adsorption capacity of Cu(II) and Pb(II) than CA, of which the adsorption isotherm modeled with Langmuir isotherms well. The adsorption capacity can significantly be affected by ionic strength and humic acid. Fourier transform infrared (FTIR) spectroscopy and X-ray photoelectron spectroscopy (XPS) results demonstrated the complexation between amino groups and Cu(II)/Pb(II) played an important role for adsorption onto CAPE.

AB - The layer-by-layer (LbL) assembly of chitosan (CH) and phosphorylated cellulose nanofibrils (P-CNF) is presented as a novel, sustainable and efficient fire protection system for polyurethane foams. The assembly yields a linearly growing coating where P-CNF is the main component and is embedded in a continuous CH matrix. This CH/P-CNF system homogenously coats the complex 3D structure of the foam producing a nano-exoskeleton that displays excellent mechanical properties increasing the modulus of the foam while maintaining its ability of being cyclically deformed. During combustion the CH/P-CNF exoskeleton efficiently prevents foam collapse and suppresses melt dripping while reducing the heat release rate peak by 31% with only 8% of added weight. The coating behavior during combustion is investigated and correlated to the observed performances. Physical and chemical mechanisms are identified and related to the unique composition and structure of the coating imparted by the LbL assembly.

AB - Alginate (Alg) hydrogels, the most popular natural biomaterials, mimic the extracellular matrix (ECM) microenvironment and offer potential biomedical applications. Despite their excellent properties such as biocompatibility, hydrophilicity and ionic crosslinking, the absence of an intrinsic cell adhesion domain lessens their cell-carrier applications in tissue engineering. Herein, we suggest a three-dimensional (3D) cell culture system by integrating Alg hydrogel and fibroblast-derived matrix (FDM). FDM including cell-adhesion motifs, signaling, and physico-mechanical cues is prepared by the decellularization process by avoiding unfavorable chemical reactions. This cues-integrated biomaterials (CiB) 3D platform shows increased cell viability, proliferation, chondrogenic and osteogenic differentiation of human bone-marrow-derived mesenchymal stem cells (hMSCs) in situ. The results show that the Alg/FDM hydrogel (CiB) matrix provides an excellent microenvironment for cell adhesion and can control the differentiation of hMSCs into specific lineages. Thus, these results suggest the potential applications of the Alg/FDM hydrogel matrix as a viable 3D culture system for tissue regeneration.

AB - Cocoa husks were used as the source for the pectin extraction by sugar acid treatment. A full factorial design was applied to screen the independent variables influencing the yield and uronic acid content. Followed by response surface methodology (RSM) was conducted using central composite design to optimize the extraction conditions. The optimized extraction condition was denoted as pH 2.5/95 degrees C/45 min. The yield and the uronic acid content of the extracted pectin was determined as 4.2 +/- 0.12% and 74.5 +/- 0.3% respectively. The extracted pectin was proved to be low methoxy pectin (LM pectin) with an 8.1% degree of esterification (DE). The pectin solutions showed shear thinning behaviour which was explicated by Williamson model. This work promotes environmentally friendly technology for pectin isolation.

AB - Electrically conductive cellulose nanopapers (EC-CNPaps) were fabricated by the droplet-coating of multiwall carbon nanotubes (MWCNTs) on cellulose nanopapers (CNPaps), and the effects of the process factors on the electrical conductivity of EC-CNPaps were investigated. The type of CNPaps (made of softwood nanofibrillated cellulose or bacterial cellulose nanofibres), the drying methods of CNPaps (air drying, freeze drying, and oven drying), the applied method for the stabilisation and the concentration of MWCNT-water solutions, and the droplet coating temperatures (~23 degrees C and ~60 degrees C) were the examined variable factors. Overall, the oven-dried nanofibrillated cellulose paper as a substrate, 0.1 wt. % of the gum Arabic stabilised MWCNT-water solution ink, and the droplet coating at 60 degrees C were introduced as the optimum conditions of the examined process factors in this study.

AB - Biocompatible, pH-sensitive and charge-conversion micelles derived from hyaluronic acid (HA), poly(lactide) (PLA) and half-generation of sectorial poly(amidoamine) dendrimers (sPA G4.5) were designed and fabricated to target delivery of docetaxel (DTX) to cancer cells. The novel micelles (HA-PALA-DTX) possessed stability against rat plasma and were capable of reversing surface zeta potential under acidic conditions in the presence of HAase. Moreover, the blank micelles demonstrated satisfactory biocompatibility and viability for biomedical applications. A cellular internalization experiment indicated that HA played an important role in increasing intracellular accumulation of DTX delivered by the micelles. Compared to Taxotere(r) and PALA-DTX, HA-PALA-DTX showed an enhanced anticancer activity in vivo, with a tumor growth inhibition rate of 72.32 +/- 5.22%. Overall, the functionalized micelles could be utilized as an alternative carrier for effective targeted delivery of anticancer agents to improve therapeutic efficacy and minimize adverse effects. PMID- 30287031 TI - Electroactive polyaniline/silica hybrid gels: Controllable sol-gel transition adjusted by chitosan derivatives. AB - In this study, the electroactive hybrid gels with controllable sol-gel process were fabricated based on the water soluble polyaniline complex and water soluble silica precursor. beta-cyclodextrin grafted on chitosan (CSCD) acted as a template, a new route for the synthesis of water soluble polyaniline complex (PA@CSCD) was designed by in-situ polymerization. Then, the hybrid silica gels without severe shrinkage were prepared by mixing PA@CSCD complex with water soluble precursor (tetrakis(2-hydroxyethyl)orthosilicates, THEOS). By dynamic rheological measurements, it was found that PA@CSCD complex could trigger and accelerate the sol-gel transition of the silica precursor. The gelation time could be largely shortened with the increase of PA@CSCD complex amount. By SEM observation, the PA@CSCD complex could be well compatible with the silica matrix. Moreover, the hybrid gels showed the good redox electroactivity, which could be successfully applied in a HRP-based biosensor. PMID- 30287032 TI - Influence of cations on texture, compressive elastic modulus, sol-gel transition and freeze-thaw properties of kappa-carrageenan gel. AB - The influences of 4 mono- and di-valent cations (K+, Na+, Mg2+ and Ca2+) on the mechanical, sol-gel transition and freeze-thaw properties of kappa-carrageenan gel were investigated. Texture profile analysis results demonstrated that the texture behavior of gelatinized kappa-carrageenan was obviously influenced by the cation types and concentrations and the influence of K+ was the greatest. The gelling temperature (Tg) of kappa-carrageenan gel showed a positive correlation with cation concentrations and the influence of K+ was still the largest. However, the viscosities of kappa-carrageenan gels evoked by divalent cations were higher than monovalent cations. Furthermore, cations reduced freeze-thaw stability of kappa-carrageenan gels and followed the same influence tendency as viscosities. It was proposed that divalent cations form direct crosslinking between kappa-carrageenan helices while monovalent cations only bind single sulphate groups on kappa-carrageenan molecules. There were more junction zones in divalent cations invoked gels. Furthermore, K+ and Ca2+ cations showed apparent synergistic effect in the research.

AB - Antrodia cinnamomea is a polyporaceous medicinal and native fungus in Taiwan. In this study, we found that AC-SPS-F3, a sulfated glucan from A. cinnamomea, reduced lung cancer cell viability via inhibition of EGFR and mTOR activity. The co-administration of AC-SPS-F3 and cisplatin synergistically inhibited lung cancer cell viability. We identified AC-SPS-F3 was a sulfated beta-(1->4)-d glucan with two long 1,6-branches in each repeat unit. The FT-IR absorption at 1341 cm-1 and 887 cm-1 confirmed the existence of sulfates. The proposed repeat unit of AC-SPS-F3, including the types of main skeleton and side chains, as well as the position of the minor galactopyranosyl and mannopyranosyl residues, were proposed according to the 1D and 2D NMR spectra, shown as follows: The features for the proposed repeat unit of AC-SPS-F3 included two long beta-(1->6)-Glcp branches, a very high ratio of sulfate substitution, and partial 2-O and 4-O substituents evenly distributed on the beta-(1->6)-Glcp branches. The present study is first to characterize the highly branched sulfated polysaccharides and elucidates its anti-cancer functions. PMID- 30287034 TI - Facile strategy involving low-temperature chemical cross-linking to enhance the physical and biological properties of hyaluronic acid hydrogel. AB - Here, we present a novel strategy to fabricate hyaluronic acid (HA) hydrogels with excellent physical and biological properties. The cross-linking of HA hydrogel by butanediol diglycidyle ether (BDDE) was characterized under different reaction temperatures, and the resulting physical properties (i.e., the storage modulus and swelling ratio) were measured. The ratio between the cross-linking rate (a strengthening effect) and the hydrolysis rate (a weakening effect) was much greater with lower cross-linking temperatures after sufficient cross-linking time, resulting in a noticeably higher storage modulus. As the cross-linking temperature decreased, the formed HA hydrogel structure became denser with smaller pores. Moreover, the introduction of low-temperature HA cross-linking strategy also resulted in an enhanced several important characteristics of HA hydrogels including its enzymatic resistivity and its ability to elicit a cellular response. These results indicate the performance of HA hydrogels can be markedly enhanced without further additives or modifications, which is expected to contribute to the advancement of applications of HA hydrogels in all industrial fields. PMID- 30287035 TI - An arabinogalactan-glycoconjugate from Genipa americana leaves present anticoagulant, antiplatelet and antithrombotic effects. AB - Glycoconjugates extracted from Genipa americana leaves (PE-Ga) were separated into two fractions, denominated as PFI and PFII (total carbohydrate: 23 36%/uronic acid: 9-30%; protein:4-5%; polyphenols:0.776-0.812 mg/g), mainly composed by arabinose, galactose and uronic acid and presenting high (PFI) and low (PFII) molecular weight (based on polyacrylamide electrophoresis gel and gel permeation chromatography). Uronic acid was also detected by FT-IR (wavenumbers: 1410 and 1333 cm-1) and NMR (alpha-GalpA). Deproteinization of glycoconjugates showed reduced protein and polyphenol levels with loss of its biological effects. PE-Ga and PFII prolonged clotting time-aPTT (3.6 and 1.8x), while PE-Ga and PFI inhibited by 48% (100 MUg/MUL) the ADP-induced platelet aggregation. In vivo, these glycoconjugates at 1 mg/kg inhibited (37-53%) venous thrombus formation (4.7 +/- 0.1 mg) and increased bleeding time (PE-Ga and PFI:3.0x; PFII:1.7x vs. PBS:906 +/- 16.7 s). In conclusion, the arabinogalactan-rich glycoconjugate of G. americana leaves, containing uronic acid, present antiplatelet, anticoagulant (intrinsic/common pathway) and antithrombotic effects, with low hemorrhagic risk.

AB - Sulfated polysaccharides, such as glycosaminoglycans (GAG) regulate various biological activities through their interactions with growth factors. Investigating these interactions becomes the key to understand the structure function relationship of GAG. Highly sulfated derivatives prepared from the marine GY785 exopolysaccharide (EPS) produced by the deep-sea hydrothermal vent bacterium Alteromonas infernus have previously shown to stimulate the chondrogenic differentiation of mesenchymal stem cells in the presence of Transforming Growth Factor-beta1 (TGF-beta1). Here, the interactions between the GAG-mimetic GY785 EPS derivatives and TGF-beta1 were investigated by Atomic Force Microscopy (AFM). The affinity between slightly sulfated or highly sulfated derivatives and TGF-beta1 was explored by AFM imaging and single-molecule force spectroscopy experiments. The number of measured interactions and the interaction strength were both higher for highly sulfated derivative compared to the slightly sulfated one. These results clearly emphasize the involvement of sulfate groups in the protein binding and open new ways to tune cellular processes by designing macromolecules with adjustable sulfate charge density.

AB - Polyamidoamine (PAMAM) dendrimers of G1.0 and 2.0 were synthesized by the repeated Michael addition and ester aminolysis of ethylenediamine and methyl acrylate. Through the reductive amination reaction of primary amines in PAMAM and carbonyl groups in 4-oxo-2,2,6,6-tetramethylpiperidine-1-oxyl (4-oxo-TEMPO), the water-soluble PAMAM immobilized TEMPO (PAMAM-TEMPO) was successfully prepared. The obtained PAMAM-TEMPO was characterized by Fourier transform infrared spectroscopy (FT-IR) and ultraviolet-visible spectrophotometer (UV-vis). PAMAM TEMPO was used as catalyst instead of free TEMPO for selective catalytic oxidation of primary hydroxyl groups in cellulose with water as reaction medium. The results showed that the catalytic performance of G1.0 PAMAM-TEMPO with 28.8% TEMPO loading was equivalent to free TEMPO. After salting out the supernatant of oxidation mixture, PAMAM-TEMPO was recovered by extraction with N,N dimethylformamide and reused for further oxidation cycles. No significant reduction in catalytic performance was found after 4 oxidation cycles. The recovery of PAMAM-TEMPO after each cycle was about 90%. By sonication of oxidized cellulose obtained with G1.0 PAMAM-TEMPO as catalyst, the individualized cellulose nanofibers with approximately 10 nm in diameter were successfully prepared. This is the first report on the use of immobilized TEMPO catalysts comparable to the performance of free TEMPO to oxidize cellulose in water. PMID- 30287038 TI - Superhydrophobicity, UV protection and oil/water separation properties of fly ash/Trimethoxy(octadecyl)silane coated cotton fabrics. AB - The presented study proposed simple and low-cost approach for improvement in UV protection and superhydrophobic properties of cotton fabrics by coating of mechanically activated fly ash particles. The maximum UV blocking was observed for 3 wt% fly ash, where UV transmittance decreased from 14.19% of untreated fabric to 0.11% of coated fabric. After subsequent treatment of Trimethoxy(octadecyl)silane (OTMS) on fly ash coated fabrics, the water contact angle was increased to 143 degrees , 147 degrees and 153 degrees for fly ash concentration of 1, 2 and 3 wt% respectively. From Cassie-Baxter theories, the unwetted fraction of air pockets were estimated to be 43%, 55% and 67% respectively for 1, 2 and 3 wt% of fly ash particles. Furthermore, the coated fabrics showed great potentials for separation of floating oil layer, underwater oil droplet or oil/water mixture. The separation efficiency of 98%, 96%, 97% and 95% was obtained for selected model oils toluene, n-hexane, chloroform and petro ether, respectively. PMID- 30287039 TI - Ganoderma atrum polysaccharide improves doxorubicin-induced cardiotoxicity in mice by regulation of apoptotic pathway in mitochondria. AB - The present study aimed to determine the cardioprotective effect of Ganoderma atrum polysaccharide (PSG-1) in doxorubicin (DOX)-treated mice and its underlying mechanism. Results indicated that PSG-1 treatment significantly alleviated DOX induced myocardial damage via attenuating apoptosis and maintaining the structure of myocardial mitochondria. Meanwhile, PSG-1-evoked cardioprotection was associated with an increase of manganese superoxide dismutase activity and decrease of caspases activities. Moreover, administration of PSG-1 suppressed DOX induced mitochondrial disorders, which was evidenced by reducing reactive oxygen species, elevating mitochondrial membrane potential and inhibiting the opening of mitochondrial permeability transition pore. PSG-1 was also found to reduce the release of cytochrome c from mitochondria to cytoplasm in mice subjected to DOX. Finally, our findings have provided comprehensive evidence for the cardioprotective effects of PSG-1 via reduction of apoptosis mediated by modification of the mitochondrial intrinsic apoptotic pathway, indicating that PSG-1 could be developed as an effective therapeutic strategy to prevent DOX induced cardiotoxicity in clinical settings. PMID- 30287040 TI - Green functionalization of cellulose nanocrystals for application in reinforced poly(methyl methacrylate) nanocomposites. AB - Cellulose nanocrystals (CNC) were carboxylated through an organic solvent free esterification method using l-malic acid (MA) to improve performance of transparent poly(methyl methacrylate) (PMMA) nanocomposites. A series of CNC carboxylated with a degree-of-substitution (DS) of 0, 0.035, and 0.20 were obtained. The presence of grafted carboxyl groups was characterized by Fourier transform infrared (FT-IR) spectroscopy and 13C NMR analysis, meanwhile effects of content and DS of CNC on the structure, thermal, mechanical, and optical transparency properties of the nanocomposites were assessed. The results indicated that the homogeneous dispersion of CNC and a favorable PMMA-CNC interface were necessary to enhance the properties of nanocomposites. Facilitated through hydrogen bonding interactions, the resulting films demonstrated that a low percentage loading of CNC with high DS worked as effective reinforcing agents, producing stronger and tougher films than neat PMMA films, with an improved thermal stability and retention of good transparency. PMID- 30287041 TI - Bioperformance of chitosan/fluoride-doped diopside nanocomposite coatings deposited on medical stainless steel. AB - This work focuses on the structure, bioactivity, corrosion, and biocompatibility characteristics of chitosan-matrix composites reinforced with various amounts of fluoride-doped diopside nanoparticles (at 20, 40, 60, and 80 wt%) deposited on stainless steel 316 L. Bioactivity studies reveal that the presence of the nanoparticles in the coatings induces apatite-forming ability to the surfaces. Based on electrochemical impedance spectroscopy and polarization experiments, the in vitro corrosion resistance of the substrate was enhanced by increasing the level of the nanoparticles in the coating. The sample containing 60% of the nanoparticles presented the highest osteoblast-like MG63 cell viability, in comparison to the other prepared and even control samples. Also, the cell attachment on the surfaces was improved with increasing the amount of the nanoparticles in the coatings. It is eventually concluded that the application of chitosan/fluoride-doped diopside nanocomposite coatings improves the bioperformance of metallic implants. PMID- 30287042 TI - Porous chitosan microspheres as microcarriers for 3D cell culture. AB - Highly porous chitosan microspheres (CSM) were prepared through emulsion-based thermally induced phase separation (TIPS) without using toxic crosslinkers and chemical porogenic agents other than ice. The CSM had an average diameter of ~150 MUm with interconnected pores varying from 20~50 MUm in size. Due to their excellent biocompatibility and unique porous structure, high-performance hepatocyte culture in three-dimensional (3D) space was achieved using the CSM as microcarriers, as cell growth also took place within the internal pores of the CSM, besides their external surface, and multidirectional cell-cell interactions were observed. Enhanced cellular activity and functions were obtained with the CSM microcarriers as compared with 2D cell culture. It is believed that these CSM microcarriers provide a promising platform for 3D cell culture in vitro. PMID- 30287043 TI - Surfactant-free emulsion Pickering polymerization stabilized by aldehyde functionalized cellulose nanocrystals. AB - Aldehyde-functionalized cellulose nanocrystals (CN) with two aldehyde contents were produced by periodate oxidation and gentle sonication. The aldehyde functionalized CNCs were shown to be an effective stabilizer in the Pickering emulsion polymerization of acrylate monomers using potassium persulfate (KPS)/metabisulfite redox initiation system at 50 degrees C without any added surfactant. The effect of CNC content on the particle size, zeta-potential, colloidal stability and film properties were discussed. CNCs with the highest aldehyde content impart better colloidal stability to the polymer dispersion and lower particle size. The stabilization process was explained by the reaction of bisulfite with aldehyde groups borne by CNC, forming an adduct that contributes to the initiation of the polymerization and nucleation of polymer particles. This favors the effective attachment of CNCs onto the polymer particle, which is prerequisite for the effective Pickering stabilization process. The optical and mechanical properties of the nanocomposite films obtained by simple casting of the polymer dispersion and water evaporation were also investigated by transmittance and dynamic mechanical analysis (DMA). Better transparency was observed for films prepared in the presence of CNCs with the highest aldehyde content, while a reverse trend was noted for the mechanical properties. PMID- 30287044 TI - Hyaluronic acid based nanocrystals hydrogels for enhanced topical delivery of drug: A case study. AB - The objective of this study is to use a carbohydrate polymer hyaluronic acid (HLA) as matrix to design novel transdermal nanogel loading poorly soluble drug nanocrystals. Baicalin nanocrystals (BCA-NC) were prepared by coupling homogenization technology and spray-drying technology. The morphology, the rheological behavior and transdermal permeation studies of HLA based BCA-NC-gel were evaluated. The results demonstrated that the BCA-NC could be successfully prepared in terms of trehalose after spray-drying. The trehalose could prevent the aggregation of BCA-NC during spray-drying. It was discovered that, the BCA-NC gel with 1% HLA possessed the favorable gelatin capacity and thinning shear rheological property. In vitro transdermal permeation studies of BCA-NC-gel/HLA studies indicated a marked increase in the skin permeation of BCA. And the transdermal flux of BCA-NC-gel with 1% HLA were 20.65-fold higher (p < 0.01) than that of coarse BCA-gel, which could be attributed to particles size reduction of BCA-NC and bioadhesive property of HLA. And the morphology characterization of BCA-NC-gel/HLA demonstrated that BCA-NC could be imprisoned into the gel network of HLA, which might prevent it from aggregation in gel. In conclusion, HLA based nanogel system is a promising carrier for effectively transdermal delivery of poorly soluble drug. PMID- 30287045 TI - Macroporous alginate foams crosslinked with strontium for bone tissue engineering. AB - Nowadays, the need of novel strategies to repair and regenerate bone defects in the field of biomedical applications has increased. Novel approaches include the design of natural bioactive scaffolds mimicking bone tissue. These bioactive scaffolds have to possess biophysical properties suitable to address biological response towards newly bone tissue formation. In particular, scaffold porosity and pore size play a pivotal role in cell migration, adhesion and proliferation, thus increasing cell-material surface interaction and osteogenic signals transmission. Here we propose the development of macroporous alginate foams (MAFs) with porous and well interconnected structure, useful to enhance growth and osteogenic differentiation of human Mesenchymal Stem Cells (hMSCs). Moreover, in this study we report a new method for MAFs fabrication based on the combination of internal gelation technique with gas foaming. Strontium was employed in combination with calcium as cross-linking agent for the alginate chains and as enhancer of the osteogenic differentiation. The influence of strontium ions on the gelation kinetics, physical properties and degradation in physiological medium of MAFs was investigated. Our results suggest that the combination of internal gelation technique with gas foaming followed by freeze drying is an easy and straightforward procedure to prepare alginate foams with high porosity and interconnectivity, able to support cell infiltration. Finally, biological assays showed how scaffolds with high strontium content are able to support cell growth and differentiation in long times by promoting osteogenic marker expression. PMID- 30287046 TI - Coupling chitosan and TEMPO-oxidized nanofibrilliated cellulose by electrostatic attraction and chemical reaction. AB - This study reports coupling methods of chitosan (CTS) and TEMPO-oxidized nanofibrilliated cellulose (TONCs). Coupling chitosan, a cationic polysaccharide, to anionic TONCs is preformed through physical crosslinking via ionic bond formation at room temperature and carefully controlled pH and mass ratio. After heating, the carboxyl group of TONCs and the ammonium group of chitosan react into an amide covalent bond linkage CONH. Fourier Transform infrared spectroscopy, 13C solid-state nuclear magnetic resonance, are used to confirm the bonds. Films of the modified TONC are produced by casting and exchanging method and atomic force microscopy and thermogravimetric analysis was used to study the film properties. Further, the tensile strength of the CTS-TONCs films is improved for the covalent bond produced indicating a straight forward method to augment the properties of these all-polysaccharide films. PMID- 30287047 TI - Multifunctional laminarin microparticles for cell adhesion and expansion. AB - Microfabrication technologies have been widely explored to produce microgels that can be assembled in functional constructs for tissue engineering and regenerative medicine applications. Here, we propose microfluidics coupled to a source of UV light to produce multifunctional methacrylated laminarin microparticles with narrow distribution of sizes using photopolymerization. The multifunctional microparticles were loaded with platelet lysates and further conjugated with an adhesive peptide. The adhesive peptides dictated cell adhesiveness to the laminarin microparticles, the incorporation of platelet lysates have resulted in improved cell expansion compared to clear microparticles. Overall, our findings demonstrate that multifunctional methacrylated laminarin microparticles provide an effective support for cell attachment and expansion. Moreover, expanded cells provide the link for microparticles aggregation resulting in robust 3D structures. This suggest the potential for using the methacrylated laminarin microplatforms capable to be assembled by the action of cells to rapidly produce large tissue engineered constructs. PMID- 30287048 TI - Strategy to improve the characterization of chitosan by size exclusion chromatography coupled with multi angle laser light scattering. AB - Here we present SEC-MALLS study for chitosan samples with weight average molar mass Mw between 33 and 427 kg/mol on columns packed with 8 MUm porous particles. A low injection concentration on the order of 0.1-0.2 mg/mL must be used to avoid overloading of the SEC columns, due to the extended coil conformation of cationic chitosan in the dilute acid buffer as compared to neutral polymers. Additionally, SEC must be performed at an eluent flow rate no more than 0.5 mL/min for high molar mass chitosan samples. At flow rates of 1.0 and 1.5 mL/min, the elution of the largest chitosan species is delayed, which leads to a distortion of the molar mass distribution towards lower molar mass region. Such an abnormal behavior is due to a chromatographic mode transition from SEC to slalom chromatography, originated from the coil-stretch transition of chitosan chains in elongational flow through the packed columns.

PMID- 30287050 TI - Serum FABP4 concentrations decrease after Roux-en-Y gastric bypass but not after intensive medical management. AB - BACKGROUND: Serum concentrations of fatty acid binding protein 4, an adipose tissue fatty acid chaperone, have been correlated with insulin resistance and cardiovascular risk factors. The objective of this study were to assess relationships among Roux-en-Y gastric bypass, intensive lifestyle modification and medical management protocol, fatty acid binding protein 4, and metabolic parameters in obese patients with severe type 2 diabetes mellitus; and to evaluate the relative contribution of abdominal subcutaneous adipose and visceral adipose to the secretion of fatty acid binding protein 4. METHODS: Participants were randomly assigned to intensive lifestyle modification and medical management protocol (n = 29) or to intensive lifestyle modification and medical management protocol augmented with Roux-en-Y gastric bypass (n = 34). Relationships among fatty acid binding protein 4 and demographic characteristics, metabolic parameters, and 12-month changes in these values were examined. Visceral and subcutaneous adipose tissue explants from obese nondiabetic patients (n = 5) were obtained and treated with forskolin to evaluate relative secretion of fatty acid binding protein 4 in the different adipose tissue depots. RESULTS: The intensive lifestyle modification and medical management protocol and Roux-en-Y gastric bypass cohorts had similar fasting serum fatty acid binding protein 4 concentrations at baseline. At 1 year, mean serum fatty acid binding protein 4 decreased by 42% in Roux-en-Y gastric bypass participants (P = .002) but did not change significantly in the intensive lifestyle modification and medical management protocol cohort. Percentage of weight change was not a significant predictor of 12-month fatty acid binding protein 4 within treatment arm or in multivariate models adjusted for treatment arm. In adipose tissue explants, fatty acid binding protein 4 was secreted similarly between visceral and subcutaneous adipose tissue. CONCLUSION: After Roux-en-Y gastric bypass, fatty acid binding protein 4 is reduced 12 months after surgery but not after intensive lifestyle modification and medical management protocol in patients with type 2 diabetes mellitus. Fatty acid binding protein 4 was secreted similarly between subcutaneous and visceral adipose tissue explants. PMID- 30287052 TI - The burden of Parkinson's disease: a worldwide perspective. PMID- 30287053 TI - Celastrol Reverses Palmitic Acid-Induced Insulin Resistance in HepG2 Cells via Restoring the miR-223 and GLUT4 Pathway. AB - OBJECTIVES: The natural triterpenoid compound celastrol ameliorates insulin resistance (IR) in animal models, but the underlying molecular mechanism is unclear. In this study, we investigated how celastrol regulates IR. METHODS: The HepG2 cellular IR model was initially established with palmitic acid (PA). The expression and activity of glucose transporter 4 (GLUT4), insulin receptor substrate-1 (IRS1) and 9 microRNAs (miRNAs) (miR-7, -34a, -96, -113, -126, -145, 150, -223 and -370) were detected before and after celastrol treatment using the PA-induced HepG2 IR model. RESULTS: The results showed that 250 uM PA for >=2 days was optimal for inducing IR in HepG2 cells; 600 nM celastrol significantly attenuated the PA-induced IR in HepG2 cells. The PA-induced GLUT4 and IRS1 downregulation and Ser307 phosphorylation on IRS1 was reversed by subsequent treatment with 600 nM celastrol for 6 h. We next investigated which IR-related miRNAs were possible upstream regulators of celastrol-mediated reversal of PA induced HepG2 IR. Two miRNAs, miR-150 and -223, were significantly downregulated by PA and were re-raised by subsequent celastrol treatment; and miR-223 was upstream of miR-150. Moreover, knocking down miR-223 abolished celastrol's anti IR effects in the PA-induced model. CONCLUSIONS: Collectively, our results demonstrated that celastrol reverses PA-induced IR-related alterations, in part via miR-223 in HepG2 cells. Further investigation is warranted for establishing the clinical potential of celastrol in treating IR-related disorders. PMID- 30287051 TI - Global, regional, and national burden of Parkinson's disease, 1990-2016: a systematic analysis for the Global Burden of Disease Study 2016. AB - BACKGROUND: Neurological disorders are now the leading source of disability globally, and ageing is increasing the burden of neurodegenerative disorders, including Parkinson's disease. We aimed to determine the global burden of Parkinson's disease between 1990 and 2016 to identify trends and to enable appropriate public health, medical, and scientific responses. METHODS: Through a systematic analysis of epidemiological studies, we estimated global, regional, and country-specific prevalence and years of life lived with disability for Parkinson's disease from 1990 to 2016. We estimated the proportion of mild, moderate, and severe Parkinson's disease on the basis of studies that used the Hoehn and Yahr scale and assigned disability weights to each level. We jointly modelled prevalence and excess mortality risk in a natural history model to derive estimates of deaths due to Parkinson's disease. Death counts were multiplied by values from the Global Burden of Disease study's standard life expectancy to compute years of life lost. Disability-adjusted life-years (DALYs) were computed as the sum of years lived with disability and years of life lost. We also analysed results based on the Socio-demographic Index, a compound measure of income per capita, education, and fertility. FINDINGS: In 2016, 6.1 million (95% uncertainty interval [UI] 5.0-7.3) individuals had Parkinson's disease globally, compared with 2.5 million (2.0-3.0) in 1990. This increase was not solely due to increasing numbers of older people, because age-standardised prevalence rates increased by 21.7% (95% UI 18.1-25.3) over the same period (compared with an increase of 74.3%, 95% UI 69.2-79.6, for crude prevalence rates). Parkinson's disease caused 3.2 million (95% UI 2.6-4.0) DALYs and 211 296 deaths (95% UI 167 771-265 160) in 2016. The male-to-female ratios of age standardised prevalence rates were similar in 2016 (1.40, 95% UI 1.36-1.43) and 1990 (1.37, 1.34-1.40). From 1990 to 2016, age-standardised prevalence, DALY rates, and death rates increased for all global burden of disease regions except for southern Latin America, eastern Europe, and Oceania. In addition, age standardised DALY rates generally increased across the Socio-demographic Index. INTERPRETATION: Over the past generation, the global burden of Parkinson's disease has more than doubled as a result of increasing numbers of older people, with potential contributions from longer disease duration and environmental factors. Demographic and potentially other factors are poised to increase the future burden of Parkinson's disease substantially. FUNDING: Bill & Melinda Gates Foundation. PMID- 30287054 TI - The Health and Health Care of Adults With Type 1 And 2 Diabetes Across the Spectrum of Estimated Glomerular Filtration Rates. AB - OBJECTIVES: Little is known about the health and health-care patterns of patients with diabetes according to their estimated glomerular filtration rates, especially within a publicly funded health-care system. METHODS: Using linked health-care databases in Ontario, Canada, we performed a population-based study of adults 50 years of age and older (mean age, 68 years) with prevalent diabetes on January 1, 2014. We categorized patients according to their levels of kidney function (estimated glomerular filtration rate >=90, 60 to 89, 30 to 59, 15 to 29 or <15 mL/min/1.73 m2, or the receipt of ongoing maintenance dialysis). We then followed patients for 2 years to determine: 1) their level of contact with health care providers (i.e. visits to family doctors, specialists); 2) their use and repeated use of acute medical services (i.e. hospitalizations and emergency department encounters; 3) diabetes-related monitoring and screening (i.e. glycated hemoglobin and cholesterol tests, vision screening); 4) glycemic and lipid control; and 5) diabetes-related outcomes. RESULTS: There were 569,384 patients in our study. Most had estimated glomerular filtration rates between 60 and 89 mL/min/1.73 m2. At baseline, patients with lower kidney function had longer durations of diabetes and more comorbidities. Over 2 years of follow up, they had higher burdens of medical care, excessive diabetes monitoring and were underscreened for diabetes-related complications. Although metabolic control was reasonable across groups, patients with low kidney function had more hospital encounters and more diabetes-related complications. CONCLUSIONS: Patients with diabetes and low kidney function are a vulnerable population that faces health system challenges and care gaps. Suggestions for policy and practice are discussed. PMID- 30287055 TI - Independent of left ventricular mass, circulating inflammatory markers rather than pressure load are associated with concentric left ventricular remodelling. AB - BACKGROUND: A reason for concentric left ventricular (LV) remodelling predicting cardiovascular outcomes independent of conventional risk factors and LV mass (LVM) has not been provided. We hypothesized that independent of LVM, concentric LV remodelling is associated with inflammatory changes rather than a pressure load on the LV. METHODS: In 764 randomly selected community participants, we assessed relations between several inflammatory markers (ELISA) and LV relative wall thickness (RWT) (echocardiography), LV mass index (LVMI), and indexes of diastolic function. RESULTS: No independent relations were noted between circulating concentrations of inflammatory markers and LVM index (LVMI) (p > 0.13 for all). However, independent of confounders including LVMI and blood pressure (BP), circulating tumour necrosis factor-alpha (TNF-alpha) (partial r = 0.14, p < 0.0005) and to a lesser degree interleukin-6 (partial r = -0.09, p < 0.02) were associated with RWT. The impact (standardized beta-coefficient) of TNF-alpha on RWT (0.12 +/- 0.03, p < 0.0005) was at least as strong as age (0.13 +/- 0.05, p < 0.005), and second only to LVMI (0.27 +/- 0.04, p < 0.0001), whilst neither office, 24-hour, central aortic BP, nor aortic stiffness were associated with RWT independent of LVMI. With adjustments, as compared to participants with a normal LVMI and geometry (12.7 +/- 0.8), circulating TNF-alpha concentrations (pg/ml) were increased as much in participants with concentric LV remodelling (16.8 +/- 1.5, p < 0.05) as in those with concentric LV hypertrophy (LVH) (17.0 +/- 1.3, p < 0.005), whilst eccentric LVH (13.7 +/- 0.9) was not. No independent relations between inflammatory markers and LV diastolic function (trans-mitral and tissue Doppler) were noted. CONCLUSIONS: Independent of LVMI, a pro-inflammatory state rather than BP load is strongly associated with LV concentric remodelling. PMID- 30287056 TI - Efficacy and safety of cryoballoon ablation in the elderly: A multicenter study. AB - BACKGROUND: The prevalence of atrial fibrillation (AF) increases with age. Second generation cryoballoon (CB2)-based PVI has demonstrated encouraging clinical results in the treatment of paroxysmal (PAF) and persistent atrial fibrillation (PersAF). The objective of this study was to assess data on safety, efficacy and long-term clinical success of CB2-based pulmonary vein isolation (PVI) in patients >=75 years of age. METHODS: CB2-based PVI was performed in 104 patients >=75 years of age (elderly group) and symptomatic AF (PersAF: n = 44, 42.3%) in three highly experienced German EP centers. The data was compared to propensity score matched patients with age <75 years (n = 104, control group; PersAF: n = 45, 43.3%, p = 0.956). RESULTS: The median age of the elderly group was 77.5 [75, 80] years while it was 63 [52, 70] years of control group patients (p = 0.0001). The median procedure time was 92.5 [75, 120] minutes (elderly group) and 100 [75, 120] (control group), p = 0.124. Major complications were registered in 7/104 (6.7%) elderly patients and 7/104 (6.7%) control group patients (p = 0.999). Clinical success in terms of freedom from AF recurrence after one-year follow-up was 80% (95% CI: 72-88) and 82% (95% CI: 75-90) and after three-year follow-up 59% (95% CI: 47-74) and 49% (95% CI: 37 64) for the elderly group and the control group, respectively (p = 0.7). CONCLUSIONS: CB2-based PVI in patients >=75 years of age appears safe, is associated with low procedure times and shows promising clinical success rates equal to patients of the younger population.

AB - Both cardiac surgery and cardiac interventions are rare in pregnancy but are generally more common in the developing world. Women with known cardiac disease should receive contemporaneous preconception counselling to assess all risks associated with pregnancy including whether surgery or cardiac interventions may need to be considered prior to pregnancy. Some women may need to undergo emergency surgery or procedures during pregnancy and decisions regarding this should be multidisciplinary including cardiologists, cardiac surgeons, anaesthetists, obstetricians and neonatologists. In this review we discuss both conditions where surgery or percutaneous interventions may need to be considered and both the outcomes for the mother and her baby.

PMID- 30287060 TI - Optimization of production rate, productivity, and product concentration for a simulated moving bed process aimed atfucose separation using standing-wave-design and genetic algorithm. AB - The effectiveness of a simulated moving bed (SMB) technology in the continuous separation of fucose from a multi-component monosugar mixture, which stemmed from defatted microalgae, has recently been identified. To guarantee high economical efficiency of such fucose-production method, the comprehensive optimization of the relevant fucose-separation SMB process needs to be accomplished such that its production rate (Prate) and/or productivity (Prod) can be maximized while meeting the requirements on fucose product concentration (Cprod,F) and pressure drop (DeltaPSMB). To resolve this issue, the SMB optimization program based on standing-wave-design method and genetic algorithm was prepared and then applied to the fucose-separation SMB optimization. It was found that the Prate, under a given particle size, could reach its maximum when the column length was selected to create a balance between the effects of the two limiting factors related to Cprod,F and DeltaPSMB. It was also found that the Prate was governed by fucose yield, if the SMB would be in need of a relatively high Cprod,F; otherwise, the Prate was governed by feed flow rate. If the particle size of the SMB adsorbent was fixed at one of the commercially available ones, the SMB conditions leading to the highest Prate and the highest Prod coincided with each other. By contrast, if the particle size was included as one of optimization variables, the Prate and Prod represented a trade-off relationship. Finally, it was confirmed from the simultaneous optimization for Prate and Prod that the increase of particle size improved Prate at the cost of Prod, thereby causing the maximum Prod to be always attained at a smaller particle size than the maximum Prate regardless of the target Cprod,F level. PMID- 30287058 TI - One-year clinical outcomes in older patients with non-ST elevation acute coronary syndrome undergoing coronary angiography: An analysis of the ICON1 study. AB - AIMS: The aim of this prospective, observational study was to identify predictors of adverse outcome at one year, following invasive care of older patients with non-ST-elevation acute coronary syndrome (NSTEACS) according to frailty status. METHODS: Older patients (aged >= 75 years), presenting with NSTEACS, undergoing invasive coronary angiography with a view to revascularisation, underwent assessment of frailty, cognition, functional status and quality of life. Participants were categorised as robust, pre-frail or frail using the Fried criteria. The primary outcome comprised a composite of all-cause mortality, myocardial infarction, stroke, unplanned revascularisation and major bleeding, at one year. Cox proportional hazards regression was used to derive a multivariate risk score. RESULTS: Overall, the composite endpoint was observed in 81 participants (29%). There was a significant difference in the occurrence of the primary outcome in the 3 frailty groups (robust 18.0%, pre-frail 27.5% and frail 39%; p = 0.03; hazard ratio (HR) for frail vs. robust: 2.79, 95% Confidence Interval [CI] 1.28-6.08). Fried frailty classification, age (categorised as >=85 years), raised Killip class, systolic blood pressure on admission, history of peripheral vascular disease (PVD), problems dressing self and implantation of a bare metal stent were identified as predictors of adverse events at one year, with a C-statistic of 0.77 (95% CI 0.71-0.83). A point-based clinical risk score (FRAIL-HEART) was defined, which had a C-statistic of 0.70 (95% CI 0.63-0.77) and significantly outperformed the GRACE 2 score. CONCLUSION: Frailty is associated with adverse clinical outcomes, following invasive management of older patients with NSTEACS. The derived risk models may enable improved risk stratification in practice. PMID- 30287061 TI - Thin-layer chromatogram development with a moving pipette delivering the mobile phase onto the surface of the adsorbent layer. AB - The new approach to the development of thin-layer chromatograms is presented. For the first time we show flexible mobile phase dosage onto the surface of the adsorbent layer by moving pipette combined with precise syringe pumps. The pipette is driven into movement by computer controlled 3D machine (modified 3D printer mechanism). Delivery of the mobile phase to the adsorbent layer is equal to or lower than that of conventional development. Therefore chromatograms can be developed with optimal mobile phase velocity, adjusted to its absorption rate by the adsorbent layer. Under such conditions there is no excess of eluent on the surface of the adsorbent layer so higher performance of the chromatographic system can be obtained. Moreover chromatograms can be developed with constant linear mobile phase velocity and therefore the relationships the plate height vs. mobile phase linear velocity obtained with planar chromatography driven by capillary forces are investigated and reported. In addition the contribution of starting spot variance in total peak variance and the influence of narrowing of starting spots on performance of the chromatographic system have been studied. The results confirm a very significant starting spot variance contribution to total peak variance and consequently considerable influence of starting spot size on plate height of the separation system, when chromatogram is developed on a short distance. In the paper the advantages and disadvantages of the prototype device and its possible application are discussed. PMID- 30287062 TI - Significant sensitivity enhancement in Hadamard transform high-performance liquid chromatography by application of long modulation sequences constructed from lower order sequences. AB - Hadamard encoding, utilizing pseudo-random injection sequences with n-bit (2n-1) elements, is applied in analytical sciences to enhance the signal-to-noise ratio (S/N) of weak analyte signals. We have developed a software approach that allows using Hadamard encoding on standard HPLC systems. This strategy is only limited by the number of instructions that can be transmitted to the autosampler and its performance degrades if an accumulation of chromatographic irregularities occurs while applying long modulation sequences. Here we demonstrate that such sequences (>4000 elements) can be subdivided into suitable subsequences, which can be independently executed. The measured subchromatograms are subsequently realigned and deconvoluted yielding a chromatogram with increased S/N. This opens an avenue to achieve unprecedented sensitivity gains. In the analysis of highly diluted nucleoside samples an S/N enhancement of up to 30-fold was observed. Furthermore, we applied the method to a sample containing the antibiotic drug fidaxomicin and found a significant sensitivity improvement that strongly depends on the applied elution conditions.

AB - Compound-independent calibration (CIC) is a quantitative method that can quantify other compounds using a structure-independent compound as the calibrant. In this study, the potential and application of CIC method for the determination of polybrominated diphenyl ethers (PBDEs) using GC-ICP-MS was investigated. The effects of sample introduction conditions, the flow rate of the carrier gas, splitless delay time and the matrix of the complex sample on the response of 11 PBDEs compounds were explored. When pulsed splitless injection was used, the transmission efficiency of analytes from the inlet to the column can speed up with increasing injection temperature and pulse pressure, the elemental response of bromine of each analyte becomes closer. Under optimized chromatographic conditions, the response is independent of the compound can be found from the slope of the pure solution standard from tri- to hepta- brominated compounds (BDE 28 as reference) ranged from 0.968 to 1.001 (R2>0.998). The degradation ratio of BDE 209 in the GC-ICP/MS system was estimated by the CIC method to be 18.7%. During the determination of fish tissue sample, big difference of the elemental response ratio (BDE 28 as reference) was obtained range from 0.678 to 0.976. However, a similar elemental response was observed among isomers range from 0.990 to 1.056. This may mean that the isomers can be calibrated to each other in a complex matrix sample. The CIC method was validated by determination 3 PBDEs in NIST SRM 1947 frozen fish tissue certified reference materials using isomers as reference compounds. The recoveries of BDE 49 and BDE 66 were 105.7% and 88.1% by using BDE 47 as calibrants, and that of BDE 155 was 108.8% by using BDE 154 as calibrant. PMID- 30287064 TI - Determination of steviol glycosides in commercial extracts of Stevia rebaudiana and sweeteners by ultra-high performance liquid chromatography Orbitrap mass spectrometry. AB - Stevia rebaudiana extracts are used as sweeteners in several countries worldwide. Several extracts of diverse composition are available on the market, and their taste depends on the contents of the various steviol glycosides. This study presents an accurate method for the qualitative and quantitative determination of steviol glycosides in 40 Stevia extracts, 7 sweeteners and 3 Stevia-sweetened beverages by a UHPLC coupled to an Orbitrap mass spectrometer. The sub-2 MUm amide column provided the separation of all the target analytes in a run time of 30 min with high resolution. The effect of different eluent compositions on the ionisation efficiency of the steviol glycosides was studied. The optimal ionisation conditions were achieved in negative mode using 0.05% formic acid. Under this condition, adducts were not found, [M-H]- were the main ions and the spontaneous loss of a glucose residue at C19 was reduced. The %RSD for intra- and inter-day precision for all eleven analytes varied from 2.1 to 4.2% and 3.0-5.1%, respectively. The recoveries from spiked Stevia extract samples were greater than 95% for all analytes. Rebaudioside A was the most abundant, ranging from 23 to 102%. Nine Stevia extracts and one drink were not compliant with the European Regulation. Isosteviol was under the LOD in all samples and steviol was found in four samples in quantities in the range 0.01-0.03%. PMID- 30287065 TI - Patient Safety in Audiology.

AB - OBJECTIVE: To determine if late preterm infants are at increased risk of intermittent hypoxemic events compared with term infants. STUDY DESIGN: Prospective, cohort, observational study of late preterm infants (340/7-366/7 weeks gestational age) and term infants (390/7-416/7 weeks gestational age). Overnight pulse oximetry recordings were performed on days 2-3 after birth, at term equivalent age, and at 45 weeks postmenstrual age. The primary outcome was the frequency of intermittent hypoxemic events per hour (desaturation >=10% below the preceding baseline SpO2) on the oximetry recording on days 2-3 after birth. Data were analyzed by the Student t test and general linear mixed model. RESULTS: Eighty-five infants were enrolled (late preterm n = 43; term infants n = 42). On days 2-3 after birth, late preterm infants had more intermittent hypoxemic events than term infants (events per hour, mean +/- standard error of the mean, 2.5 +/- 1.2 vs 1.0 +/- 1.2; P < .0001). On mixed model analysis, late preterm infants had a higher frequency of intermittent hypoxemic events at term equivalent age, which decreased to a similar frequency as in term infants by 45 weeks postmenstrual age (events per hour; term equivalent age, late preterm: least squares mean, 3.7 [95% CI, 2.7-5.1] vs term: least squares mean, 1.7 [95% CI, 1.2-2.3]; 45 weeks postmenstrual age, late preterm: least squares mean, 1.5 [95% CI, 1.1-2.1] vs term: least squares mean, 1.9 [95% CI, 1.4-2.6]; P < .0005). CONCLUSIONS: Late preterm infants are at greater risk of intermittent hypoxemia than term infants soon after birth. We speculate that preventing intermittent hypoxemia in late preterm infants may improve neurodevelopmental outcomes. PMID- 30287067 TI - Adverse Childhood Experiences and Weight Status among Adolescents. AB - OBJECTIVE: To investigate the relationship between adverse childhood experiences (ACEs) and weight status among adolescents. STUDY DESIGN: Data were drawn from the Minnesota Student Survey, a large (n = 105 759), statewide, anonymous survey of public school students in eighth, ninth, and eleventh grades. Self-reported height and weight were used to calculate body mass index. Multinomial logistic regression was used to examine associations between self-reported ACEs and weight status, controlling for key sociodemographic characteristics. RESULTS: ACEs were positively associated with weight status; adolescents with more ACEs were more likely to have overweight, obesity, and severe obesity than adolescents with no ACEs. Adolescents who reported an ACE were 1.2, 1.4, and 1.5 times as likely to have overweight, obesity, and severe obesity, respectively, compared with their peers with no ACEs. There was no relationship between ACEs and underweight. CONCLUSIONS: The results of this large sample of adolescents with anonymous data support the hypothesis that ACEs and obesity are strongly associated. The directionality of this relationship needs to be understood. Moreover, these findings suggest that child health professionals may need to screen for ACEs as an important aspect of clinical weight management. PMID- 30287068 TI - Role of Genetic Susceptibility in the Development of Bronchopulmonary Dysplasia. AB - OBJECTIVE: To assess heritable contributions to bronchopulmonary dysplasia (BPD) risk in a twin cohort restricted to gestational age at birth <29 weeks. STUDY DESIGN: A total of 250 twin pairs (192 dichorionic, 58 monochorionic) born <29 weeks gestational age with known BPD status were identified. Three statistical methods applicable to twin cohorts (chi2 test, intraclass correlations [ICCs], and ACE modeling [additive genetic or A, common environmental or C, and unique environmental or E components]) were applied. Heritability was estimated as percent variability from A. Identical methods were applied to a subcohort defined by zygosity and to an independent validation cohort. RESULTS: chi2 analyses comparing whether neither, 1, or both of monochorionic (23, 19, 16) and dichorionic (88, 56, 48) twin pairs developed BPD revealed no difference. Although there was similarity in BPD outcome within both monochorionic and dichorionic twin pairs by ICC (monochorionic ICC = 0.34, 95% CI [0.08, 0.55]; dichorionic ICC = 0.39, 95% CI [0.25, 0.51]), monochorionic twins were not more likely than dichorionic twins to have the same outcome (P = .70). ACE modeling revealed no contribution of heritability to BPD risk (% A = 0.0%, 95% CI [0.0%, 43.1%]). Validation and zygosity based cohort results were similar. CONCLUSIONS: Our analysis suggests that heritability is not a major contributor to BPD risk in preterm infants <29 weeks gestational age. PMID- 30287069 TI - Preschoolers understand and generate pretend actions using object substitution. AB - Pretend play is often considered to be an imaginative or creative activity. Yet past experimental research has focused on whether children imitate pretense, follow instructions to pretend, or understand others' pretense. Thus, we cannot be sure that children's pretense is in fact novel or whether children simply copy or follow others' instructions. This is the first experiment to show that preschoolers generate their own novel object substitutions. In Study 1, 45 3- and 4-year-olds saw an experimenter use one object as another accompanied by pretend or trying cues. Children differentiated between the experimenter's intentions by imitating the actions accompanied by pretend cues and correcting the actions accompanied by trying cues. In addition, when the experimenter made her intentions to pretend or try explicit, children produced significantly more novel object substitutions not modeled or verbally requested by the experimenter within a pretend context than within a trying context. Study 2 replicated these findings with 34 3-year-olds using a repeated-measures design. However, it found no relationship between children's copying or generation of object substitutions and divergent thinking, inhibitory control, or pretense during free play. PMID- 30287070 TI - Lipoprotein apheresis in the management of severe hypercholesterolemia and hyperlipoproteinemia(a)-The Portuguese experience. AB - BACKGROUND: Low-density lipoprotein cholesterol (LDL-C) and lipoprotein(a) (Lp(a)) are established causal risk factors for cardiovascular disease (CVD). Lipoprotein apheresis is often required for treatment of patients with a high risk for CVD due to hypercholesterolemia and/or hyperlipoproteinemia(a). AIM: To describe our experience with lipoprotein apheresis in patients with severe hypercholesterolemia or with hyperlipoproteinemia(a). METHODS: We retrospectively investigated patients treated with Lipoprotein apheresis using direct adsorption of lipoproteins (DALI) technique, between December 2008 and March 2018, in our center. Adverse events, acute and long term reductions in lipid parameters were analyzed. RESULTS: Between December 2008 and March 2018, a total of 950 treatments were performed in five patients, four with heterozygous familial hypercholesterolemia (HeFH), all on maximally tolerated cholesterol-lowering drug therapy and in one patient with hyperlipoproteinemia(a) and progressive CVD. In the four patients with HeFH we obtained mean acute reductions in LDL-C and non high-density lipoprotein cholesterol (non-HDL-C) of 62.0 +/- 7.8% and 60.4 +/- 6.8%, respectively. Regarding long-term efficacy we achieved a mean reduction of 43.1% in LDL-C and of 41.2% in non-HDL-C. In the patient with hyperlipoproteinemia(a) we attained mean acute reductions of 60.4 +/- 6.4% in Lp(a) and of 75.4 +/- 7.3% in LDL-C per session and long term reductions in Lp(a) and LDL-C of 67.4% and 40.5%, respectively. Adverse events were recorded in only 1.2% of treatments. CONCLUSION: Lipoprotein apheresis is an efficient and safe treatment in severely hypercholesterolemic patients who are refractory to conservative lipid-lowering therapy or with hyperlipoproteinemia(a) and progressive CVD. PMID- 30287071 TI - Risks of leukapheresis and how to manage them-A non-systematic review. AB - Leukapheresis is like any other preparative apheresis, except it isn't: Leukapheresis typically takes much longer, larger blood volumes are processed and, consequently, larger ACD-A volumes are administered. Blood component donors and leukapheresis subjects are also quite different populations. Allogeneic donors tend to be younger and many are first-time donors, both of which are risk factors for adverse reactions during blood donation. Moreover, more than half of all leukapheresis collections are performed in patients. Here it is the age distribution, including patients at the extremes of age, as well as the underlying disease and co-morbidities which may expose them to higher, or different, risks compared to donors. Both groups thus have good reasons why adverse effects to leukapheresis might be more frequent, more severe, or even different in nature altogether. Compared to other preparative apheresis types like platelet or plasma apheresis, the risks of leukapheresis have been studied less extensively, as it is in comparison a relatively low-frequency intervention. Often leukapheresis remains a domain of hematologists who have a different sense of procedural safety than transfusionists. Furthermore, G-CSF mobilized "stem cell" aphereses by a wide margin outnumber unmobilized aphereses, so that the very strong signal from adverse reactions to G-CSF all but drowns out signals from the apheresis proper. This focused review assesses observations from leukapheresis as well as extrapolation of observations from other forms of preparative apheresis in an attempt to gauge the safety of leukapheresis and identify potential approaches to its further improvement. In short, the overall impression is one of a very satisfactory safety record of leukapheresis, with occasional issues with venous access or vasovagal problems, and frequent, but highly responsive and rarely limiting ACD-A toxicity. PMID- 30287072 TI - Instantaneous frequency as a new approach for evaluating the clinical severity of Duchenne muscular dystrophy through ultrasound imaging. AB - Duchenne muscular dystrophy (DMD) results in loss of ambulation for the patients. Ultrasound attenuation correlates with fat content in muscles, resulting in changes in signal frequency. The Hilbert-Huang transform (HHT) allows time frequency analysis with high time-frequency resolution. This study explored the feasibility of using the instantaneous frequency (IF) obtained from the HHT to diagnose the walking function of patients with DMD. Eighty-five participants (12 control and 73 patients with DMD) underwent a standard-care ultrasound examination of the gastrocnemius to acquire raw image data for ultrasound B-mode and IF calculations, which were compared with the DMD stage using Pearson correlation and receiver operating characteristic (ROC) curve analyses. With increasing DMD stage, the median IF decreased from 7.25 to 7.01 MHz (the correlation coefficient r = -0.73; the probability value p < 0.0001). The area under the ROC curve was 0.97 when using ultrasound IF to discriminate between ambulatory and nonambulatory patients (accuracy: 91.76%; sensitivity: 93.75%; and specificity: 90.57%). The study reveals that ultrasound IF has great potential in DMD evaluation and management. PMID- 30287073 TI - Numerical prediction of ultrasonic attenuation in concentrated emulsions and suspensions using Monte Carlo method. AB - For the study of predicting ultrasonic attenuation of mixed particles and probing the effect of interaction between neighboring particles, the Monte Carlo method was investigated to establish a submicron particle size characterization model in concentrated particulate two-phase system and serve as a probability and statistics technique to evaluate the underlying ultrasonic events during the ultrasound propagation. The numerical simulation method was proposed to predict the ultrasonic attenuation characteristics in the two-phase system of silica suspensions and corn oil-in-water emulsions with different particle sizes, ultrasonic frequencies and concentrations. Furthermore, an extension of the well established single-particle theory of Epstein-Carhart and Allegra-Hawley (ECAH) was carried out, by incorporated in the couple phase model from a hydrodynamic point of view and effective hypothesis both accounted for the ultrasonic wave overlapping effect for the close proximity of particles. The simulation result shows agreement with the results of the ECAH model, the Lloyd & Berry (LB) model and the Waterman model in the dilute limitation, corresponding to glass beads and silica particles respectively. Afterwards, such a method was then applied into mixed particle system, where the mixed iron particles and glass beads with various ratios were set as examples for the purpose of predicting ultrasonic attenuation for the mixed particle systems. After comparing with the experimental results, it is shown that as a function of frequency, the variation of the ultrasonic attenuation coefficient with different mixing ratio manifests a nonlinear tendency. Also noteworthy is that the physical properties of particles play a dramatic impact in influencing ultrasonic attenuation. At higher concentrations, it was validated both in two-phase system of silica suspensions and corn oil-in-water emulsions that the attenuation predicted by Monte Carlo method agreed well with the experimental results of literature, yielding a theoretically increasing but less than linear expected attenuation with particle concentration. Particularly, the critical concentration of deviation from the linear change was obtained and interpreted using the thermal and viscous overlapping theory. The proposed Monte Carlo method presents a novel approach in calculating the attenuation in high particle volume concentration of more than 40% and provides a numerical modeling of particle size measurement in the complex particle-particle interaction condition.

AB - Trans-differentiation of quiescent hepatic stellate cells (HSCs) into active myofibroblasts secretes excess amounts of extracellular matrix (ECM) proteins. miR-29b1 has the potential to treat liver fibrosis, because it targets several profibrotic genes. We previously demonstrated that miR-29b1 and the hedgehog (Hh) pathway inhibitor GDC-0449 could, together, inhibit the activation of HSCs and ECM production in common bile-duct-ligated (CBDL) mice. Herein, we determined the effect of chemical modifications of miR-29b1 on its stability, immunogenicity, and Argonaute-2 (Ago2) loading in vitro, after modifying its antisense strand with phosphorothioate (PS-miR-29b1), 2'-O-methyl-phosphorothioate (OMe-miR-29b1), locked nucleic acid (LNA-miR-29b1), and N,N'-diethyl-4-(4-nitronaphthalen-1 ylazo)-phenylamine (ZEN-miR-29b1). Chemical modifications significantly improved stability of miR-29b1 in 50% FBS. Among all the modified miRNAs tested, OMe-PS miR-29b1 showed the highest stability with low immunogenicity, without the loss of efficacy in vitro. Therefore, OMe-PS-miR-29b1 was complexed with poly(ethylene glycol)-block-poly(2-methyl-2-carboxyl-propylenecarbonate-graft-dodecanol-graft tetraethylenepentamine (mPEG-b-PCC-g-DC-g-TEPA) cationic micelles, and anti fibrotic efficacy was evaluated in CBDL mice. There was a significant improvement in liver histology and decrease in the levels of injury markers. Further, mRNA/protein levels of collagen, alpha-SMA, and TIMP-1 were significantly lower for the OMe-PS-miR-29b1-loaded micelles compared to miR-29b1-loaded micelles. In conclusion, micellar delivery of OMe-PS-miR-29b1 is a promising strategy to treat liver fibrosis. PMID- 30287075 TI - A straightforward approach for coping with unreliability of person means when parsing within-person and between-person effects in longitudinal studies. AB - Longitudinal studies enable researchers to distinguish within-person (i.e., time varying) from between-person (i.e., time invariant) effects by using the person mean to model between-person effects and person-mean centering to model within person effects using multilevel models (MLM). However, with some exceptions, the person mean tends to be based on a relatively small number of observations available for each participant in longitudinal studies. Unreliability inherent in person means generated with few observations results in downwardly biased between person and cross-level interaction effect estimates. This manuscript considers a simple, easy-to-implement, post-hoc bias adjustment to correct for attenuation of between-person effects caused by unreliability of the person mean. This correction can be applied directly to estimates obtained from MLM. We illustrate this method using data from a panel study predicting adolescent alcohol involvement from perceived parental monitoring, where parental monitoring was disaggregated into within-person (i.e., person-mean-centered) and between-person (i.e., person-mean) components. We then describe results of a small simulation study that evaluated the performance of the post-hoc adjustment under data conditions that mirrored those of the empirical example. Results suggested that, under a condition in which parameter bias is known to be problematic (i.e., moderate ICCX, small n, presence of a compositional effect), it is preferable to use the bias-adjusted MLM estimates over the unadjusted MLM estimates for between person and cross-level interaction effects.

PMID- 30287079 TI - Donor APOL1 high-risk genotypes are associated with increased risk and inferior prognosis of de novo collapsing glomerulopathy in renal allografts. AB - Collapsing focal segmental glomerulosclerosis (cFSGS) in the native kidney is associated with heavy proteinuria and accelerated renal failure. However, cFSGS in the renal allograft is less well characterized. Here we report clinico pathologic features and APOL1 donor risk genotypes in 38 patients with de novo post-kidney transplant cFSGS. Recipients were 34% female and 26% African American. Concurrent viral infections and acute vaso-occlusion (including thrombotic microangiopathy, cortical necrosis, atheroembolization, and cardiac arrest with contralateral graft thrombosis) were present in 13% and 29% of recipients, respectively. Notably, 61% of patients had concurrent acute rejection and 47% received grafts from African American donors, of which 53% carried APOL1 high-risk genotypes. These frequencies of acute rejection and grafts from African American donors were significantly higher than in our general transplant population (35% and 16%, respectively). Patients had a median serum creatinine of 5.4 mg/dl, urine protein/creatinine 3.5 g/g, and 18% had nephrotic syndrome. Graft failure occurred in 63% of patients at an average of eighteen months post index biopsy. By univariate analysis, donor APOL1 high-risk genotypes, post transplant time, nephrotic syndrome, and chronic histologic changes were associated with inferior graft survival while acute vaso-occlusion was associated with superior graft survival. Donor APOL1 high-risk genotypes independently predicted poor outcome. Compared to native kidney cFSGS, post-transplant cFSGS had more acute vaso-occlusion but less proteinuria. Thus, de novo cFSGS is associated with variable proteinuria and poor prognosis with potential predisposing factors of African American donor, acute rejection, viral infection and acute vaso-occlusion. Additionally, donor APOL1 high-risk genotypes are associated with higher incidence and worse graft survival.

AB - The present study evaluated the cytokine profile in PBMC supernatants and the humoral response in mucosal leishmaniasis (ML) patients and in healthy subjects living in an endemic area. Four proteins, which had previously proven to be antigenic in the human disease, were tested: LiHyM, enolase, eukaryotic initiation factor 5a, and Beta-tubulin. Results showed that all of the proteins stimulated human cells with higher IFN-gamma and lower IL-4 and IL-10 levels. The analysis of antibody isotypes correlated with cell response, since the IgG2 production was higher than IgG1 in both groups. By contrast, a Th2 response was found when an antigenic Leishmania extract was used. Serological analyses revealed high sensitivity and specificity values for the serodiagnosis of the disease, when compared to the data obtained using the antigenic preparation. In conclusion, this study presents new candidates to be evaluated as biomarkers in tegumentary leishmaniasis. PMID- 30287083 TI - Virtual reality exposure therapy for anxiety and related disorders: A meta analysis of randomized controlled trials. AB - Trials of virtual reality exposure therapy (VRET) for anxiety-related disorders have proliferated in number and diversity since our previous meta-analysis that examined 13 total trials, most of which were for specific phobias (Powers & Emmelkamp, 2008). Since then, new trials have compared VRET to more diverse anxiety and related disorders including social anxiety disorder (SAD), posttraumatic stress disorder (PTSD), and panic disorder (PD) with and without agoraphobia. With the availability of this data, it is imperative to re-examine the efficacy of VRET for anxiety. A literature search for randomized controlled trials of VRET versus control or in vivo exposure yielded 30 studies with 1057 participants. Fourteen studies tested VRET for specific phobias, 8 for SAD or performance anxiety, 5 for PTSD, and 3 for PD. A random effects analysis estimated a large effect size for VRET versus waitlist (g = 0.90) and a medium to large effect size for VRET versus psychological placebo conditions (g = 0.78). A comparison of VRET and in vivo conditions did not show significantly different effect sizes (g = -0.07). These findings were relatively consistent across disorders. A meta-regression analysis revealed that larger sample sizes were associated with lower effect sizes in VRET versus control comparisons (beta = 0.007, p < 0.05). These results indicate that VRET is an effective and equal medium for exposure therapy. PMID- 30287084 TI - An Inconvenient Truth: Calcium Sensors Are Calcium Buffers. AB - Recent advances in Ca2+ imaging have given neuroscientists a tool to follow the activity of large numbers of individual neurons simultaneously in vivo in the brains of animals as they are presented with sensory stimulation, respond to environmental challenges, and engage in behaviors. The Ca2+ sensors used to transduce changes in cellular Ca2+ into changes in fluorescence must bind Ca2+ to produce a signal. By binding Ca2+, these sensors can act as buffers, often reducing the magnitude of a Ca2+ change severalfold, and producing a proportional slowing of the rates of change. Ca2+ probes can thus distort the patterns of activity they are intended to study and modify ongoing Ca2+ signaling functions. Recognizing these factors will enhance the use of in vivo Ca2+ imaging in the investigation of neural circuit function.

PMID- 30287085 TI - Anti-osteoclastic effects of C-glucosidic ellagitannins mediated by actin perturbation. AB - Actin subunits assemble into actin filaments whose dynamics and three-dimensional architectures are further regulated by a variety of cellular factors to establish the functional actin cytoskeleton. The C-glucosidic ellagitannin vescalagin and its simpler analogue vescalin, affect both the dynamics and the ultrastructure of the actin cytoskeleton by directly binding to F-actin. Herein, we show that in vitro, the two compounds induce the formation of distinct F-actin networks characterized by different superstructures and dynamics. In living mature osteoclasts, highly specialized bone-degrading cells that constantly remodel their cytoskeleton, vescalagin and vescalin alter actin dynamics at podosomes and compromise the integrity of the podosome belt that forms the bone-degrading apparatus. Both compounds target the bone-resorbing activity at concentrations that preserve osteoclastic maturation and survival and with no detectable impact on the behaviour of bone-forming osteoblastic cells. This anti-osteoclastic activity of vescalagin and vescalin reveals the potential of targeting actin dynamics as a new therapeutic opportunity and, in this case, as a plausible approach for the local treatment of osteoporosis.

AB - OBJECTIVE: Studies using the estrogen receptor alpha (ERalpha) knock-out (alphaERKO) mice have demonstrated that ERalpha plays a crucial role in various estrogen-mediated metabolic regulations. ERalpha is a ligand dependent transcription regulator and its activity is regulated by estrogenic compounds. ERalpha consists of two transcriptional activation domains, AF-1 and AF-2. The activities of these domains are regulated through different mechanisms; however, the specific physiological role in metabolic regulation by these domains is still unclear. METHODS: We utilized an ERalpha AF-2 mutant knock-in mouse (AF2ERKI) to evaluate the physiological functionality of ERalpha transactivation domains. Due to the estrogen insensitive AF-2 mutation, the phenotypes of AF2ERKI mice are seemingly identical to the global alphaERKO including obesity in the females. Distinct from the alphaERKO, the AF-1 function of AF2ERKI mice can be activated by tamoxifen (Tam). Ovariectomized (OVX) AF2ERKI and WT females were treated with Tam and fed a high-fat diet (HFD) for 10 weeks. Additionally, indirect calorimetric analysis was performed using metabolic chambers with food intake and locomotor activity recorded for Tam-treated AF2ERKI and alphaERKO females. RESULTS: Obesity in HFD-fed AF2ERKI females was prevented by Tam treatment; particularly, inguinal fat accumulation was strongly blocked by Tam treatment. Alterations in fat metabolism genes, however, were not found in either inguinal fat nor visceral fat to be Tam-regulated, even though fat accumulation was strongly reduced by Tam treatment. Indirect calorimetric analysis revealed that without alteration of food intake and locomotor activity Tam treatment increased energy expenditure in AF2ERKI but not alphaERKO females. CONCLUSIONS: These results suggest that the activation of ERalpha AF-1 prevents fat accumulation. The prevention of obesity through AF-1 is mediated by induction of energy expenditure rather than ERalpha AF-1 functionality of lipid metabolism gene regulation in fat tissues. PMID- 30287091 TI - Compensatory mechanisms for methylglyoxal detoxification in experimental & clinical diabetes. AB - OBJECTIVES: The deficit of Glyoxalase I (Glo1) and the subsequent increase in methylglyoxal (MG) has been reported to be one the five mechanisms by which hyperglycemia causes diabetic late complications. Aldo-keto reductases (AKR) have been shown to metabolize MG; however, the relative contribution of this superfamily to the detoxification of MG in vivo, particularly within the diabetic state, remains unknown. METHODS: CRISPR/Cas9-mediated genome editing was used to generate a Glo1 knock-out (Glo1-/-) mouse line. Streptozotocin was then applied to investigate metabolic changes under hyperglycemic conditions. RESULTS: Glo1-/- mice were viable and showed no elevated MG or MG-H1 levels under hyperglycemic conditions. It was subsequently found that the enzymatic efficiency of various oxidoreductases in the liver and kidney towards MG were increased in the Glo1-/- mice. The functional relevance of this was supported by the altered distribution of alternative detoxification products. Furthermore, it was shown that MG dependent AKR activity is a potentially clinical relevant pathway in human patients suffering from diabetes. CONCLUSIONS: These data suggest that in the absence of GLO1, AKR can effectively compensate to prevent the accumulation of MG. The combination of metabolic, enzymatic, and genetic factors, therefore, may provide a better means of identifying patients who are at risk for the development of late complications caused by elevated levels of MG.

AB - The past decade has seen incredible advances in the field of stem cell biology that have greatly improved our understanding of development and provided important insights into pathological processes. Transcription factors (TFs) play a central role in mediating stem cell proliferation, quiescence, and differentiation. One TF that contributes to these processes is Nuclear Factor One X (NFIX). Recently, NFIX activity has been shown to be essential in multiple organ systems and to have important translational impacts for human health. Here, we describe recent studies showing the contribution of NFIX to muscle development and muscular dystrophies, hematopoiesis, cancer, and neural stem cell biology, highlighting the importance of this knowledge in the development of therapeutic targets. PMID- 30287094 TI - Immunohistochemical expression analysis of the human fetal lower urogenital tract. AB - We have studied the ontogeny of the developing human male and female urogenital tracts from 9 weeks (indifferent stage) to 16 weeks (advanced sex differentiation) of gestation by immunohistochemistry on mid-sagittal sections. Sixteen human fetal pelvises were serial sectioned in the sagittal plane and stained with antibodies to epithelial, muscle, nerve, proliferation and hormone receptor markers. Key findings are: (1) The corpus cavernosum in males and females extends into the glans penis and clitoris, respectively, during the ambisexual stage (9 weeks) and thus appears to be an androgen-independent event. (2) The entire human male (and female) urethra is endodermal in origin based on the presence of FOXA1, KRT 7, uroplakin, and the absence of KRT10 staining. The endoderm of the urethra interfaces with ectodermal epidermis at the site of the urethral meatus. (3) The surface epithelium of the verumontanum is endodermal in origin (FOXA1-positive) with a possible contribution of Pax2-positive epithelial cells implying additional input from the Wolffian duct epithelium. (4) Prostatic ducts arise from the endodermal (FOXA1-positive) urogenital sinus epithelium near the verumontanum. (5) Immunohistochemical staining of mid-sagittal and para sagittal sections revealed the external anal sphincter, levator ani, bulbospongiosus muscle and the anatomic relationships between these developing skeletal muscles and organs of the male and female reproductive tracts. Future studies of normal human developmental anatomy will lay the foundation for understanding congenital anomalies of the lower urogenital tract.

PMID- 30287096 TI - Wake-up Sleepy Gene: Reactivating Fetal Globin for beta-Hemoglobinopathies. AB - Disorders in hemoglobin (hemoglobinopathies) were the first monogenic diseases to be characterized and remain among the most common and best understood genetic conditions. Moreover, the study of the beta-globin locus provides a textbook example of developmental gene regulation. The fetal gamma-globin genes (HBG1/HBG2) are ordinarily silenced around birth, whereupon their expression is replaced by the adult beta-globin genes (HBB primarily and HBD). Over 50 years ago it was recognized that mutations that cause lifelong persistence of fetal gamma-globin expression ameliorate the debilitating effects of mutations in beta globin. Since then, research has focused on therapeutically reactivating the fetal gamma-globin genes. Here, we summarize recent discoveries, focusing on the influence of genome editing technologies, including CRISPR-Cas9, and emerging gene therapy approaches. PMID- 30287097 TI - Carbon dioxide in office diagnostic hysteroscopy: An open question. A multicenter randomized trial on 1982 procedures. AB - OBJECTIVE: to compare carbon dioxide and saline solution distension in diagnostic hysteroscopies with regards to patient discomfort and procedural time and in accordance with the instrument diameter (5 mm vs 3.5 mm). The secondary outcome was to evaluate the role of the patient age and the obstetrical history on perception of pain and procedural time. STUDY DESIGN: This is a prospective multicenter randomized study including 1982 patients that underwent office diagnostic hysteroscopy in: Policlinico Abano Terme, Universita Cattolica del Sacro Cuore in Rome and Ente Ecclesiastico Ospedale Generale Regionale "F. Miulli" in Acquaviva delle Fonti. They were firstly randomized according to distension medium and secondly according to instrument diameter. Pain perception after the procedure was assessed by VAS (Visual Analogue Scale) score and procedural time was registered. Mann-Whitney U test was used to compare data. RESULTS: Lower pain score and procedural time were recorded with the employment of Carbon Dioxide (p < 001). Patient discomfort and procedural time were significantly influenced by the instrument diameter independent of the distension medium used, though in the subgroup where gas was employed VAS score after 1 min (VAS1) resulted lower compared to saline solution in both the traditional and mini-hysteroscopy procedures (p < 001). CONCLUSION: Carbon dioxide and saline solution are both suitable distension media for outpatient diagnostic hysteroscopy; nonetheless, carbon dioxide confers advantages in terms of pain perception and procedural time. PMID- 30287098 TI - The role of neoadjuvant chemotherapy or chemoradiotherapy for advanced gallbladder cancer - A systematic review. AB - BACKGROUND: Neoadjuvant chemotherapy for advanced gallbladder cancer (GBC) has recently been proposed as an alternative to adjuvant chemotherapy, with potential increase in resectability rate and overall survival. AIM: To undertake a systematic review and critical appraisal of available literature on the use of neoadjuvant chemotherapy (NACT) or chemoradiotherapy (NACRT) in the treatment of advanced GBC. METHODS: Systematic review carried out in line with the Meta analysis Of Observational Studies in Epidemiology guidelines. Primary outcomes were clinical benefit rate (CBR) of neoadjuvant therapy, defined as percentage of complete response, partial response and stable disease, resectability rate and R0 resection. Secondary outcomes were overall and disease-free survival. RESULTS: 8 studies met the inclusion criteria (n = 474), of which 398 (84.0%) received NACT and 76 (16.0%) received NACRT. 133 of 434 patients (30.6%) had progressive disease despite NACT or NACRT. The CBR was 66.6%. 17% of the patients who responded to chemotherapy did not proceed to surgery. 50.4% of the patients were considered suitable for surgical resection, of which 191 (40.3%) underwent curative resection. The R0 rate for the whole cohort was 35.4%. Overall survival ranged from 18.5 to 50.1 months for those who underwent curative resection versus 5.0-10.8 months for non-resected group. CONCLUSIONS: There is insufficient data to support the routine use of NACT or NACRT in advanced GBC, as this has only benefited a third of whole cohort, who eventually achieved a R0 resection. Future studies should be in the form of randomized controlled trials to investigate the role of neoadjuvant therapy in advanced GBC. PMID- 30287099 TI - Variations in Hook of Hamate Morphology: A Cadaveric Analysis. AB - PURPOSE: The hook of the hamate is an anatomical structure that separates the ulnar border of the carpal tunnel from Guyon's canal and serves as a landmark for surgeons. The hook of the hamate is also subject to fracture from injury. We hypothesize that there are variations in the hook of the hamate in the general population. METHODS: One thousand pairs of hamates (2,000 hamates) from the Hamann-Todd Collection at the Cleveland Natural History Museum were analyzed. The height of the hook of the hamate and the total height of the hamate bone were measured using digital calipers. The hook height ratio was defined as the hook height divided by the total height of the hamate. Statistical analysis was performed using unpaired Student's t test to determine differences in sex and race. RESULTS: The mean hook height was 9.8 +/- 1.4 mm (range, 2.5-15.9 mm), whereas the mean hook height ratio was 0.42 +/- 0.04 (range, 0.15-0.56). There was a 3.1% (62/2,000) incidence of abnormally small hooks, which we classified as hypoplastic and aplastic. Of the hypoplastic hooks, 55% (24/44) were bilateral, whereas 44% (8/18) of the aplastic hooks were bilateral. The incidence of variation in size in the hook of the hamate was highest in white females (9.3%) and lowest in black males (1.4%). CONCLUSIONS: Abnormalities in hook of hamate anatomy are common in the general population, especially in white females. CLINICAL RELEVANCE: Knowledge of anatomic variation in the hook of the hamate may provide additional insight into surgeons' palpation of bony anatomy, interpretation of imaging studies, and use of the hook as a landmark during surgery. PMID- 30287100 TI - Management of the Posttraumatic Coronoid-Deficient Elbow. AB - Posttraumatic coronoid deficiency is one of the most challenging scenarios even for the most experienced elbow surgeon. Surgical options can be grouped into soft tissue reconstructions, autogenous corticocancellous bone graft reconstructions, osteochondral reconstructions, and prosthetic replacement. However, the literature is inconclusive with limited cases, short follow-up, and no conclusive clinical comparative studies of these techniques. This article provides a review of the current surgical options, and we offer the senior author's (S.W.O.) perspective after years of experience with many of these techniques. PMID- 30287101 TI - Absence of the Pronator Quadratus Muscle Precluding Distal Nerve Transfer. AB - The branch of the anterior interosseous nerve to the pronator quadratus (PQ) is increasingly used as a donor nerve for end-to-end and reverse end-to-side nerve transfers. The anatomy of the PQ (and its nerve branch) is generally considered reliable in the absence of prior trauma. In this report, we describe a patient with an absent PQ despite intact clinical examination of other muscles supplied by the anterior interosseous nerve. The absence of the PQ precluded the use of its nerve as a donor nerve for transfer. PMID- 30287102 TI - Epidemiology and determinants of type 2 diabetes in south Asia. AB - Type 2 diabetes has rapidly developed into a major public health problem in south Asia (defined here as Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka) in recent decades. During this period, major lifestyle changes associated with economic transition, industrialisation, urbanisation, and globalisation have been key determinants in the increasing burden of non-communicable diseases. A decline in nutrition quality, reduced physical activity, and increased sedentary behaviours are reflected in the increasing prevalence of type 2 diabetes and related risk factors in the region. The International Diabetes Federation 2017 estimates of the prevalence of diabetes in adults in the region range from 4.0% in Nepal to 8.8% in India. The prevalence of overweight ranges from 16.7% in Nepal to 26.1% in Sri Lanka, and the prevalence of obesity ranges from 2.9% in Nepal to 6.8% in Sri Lanka. An increasing proportion of children, adolescents, and women are overweight or obese, leading to a heightened risk of type 2 diabetes. Ethnic south Asians present with greater metabolic risk at lower levels of BMI compared with other ethnic groups (referred to as the south Asian phenotype), with type 2 diabetes often developing at a younger age, and with rapid progression of diabetic complications. Because of the presence of multiple risk factors and a body composition conducive to the development of type 2 diabetes, south Asians should be aggressively targeted for prevention. In this Series paper, we detail trends in the prevalence of diabetes in the region and address major determinants of the disease in the context of nutrition and physical activity transitions and the south Asian phenotype. PMID- 30287103 TI - Clinical management of type 2 diabetes in south Asia. AB - Compared with other ethnic groups, south Asian people with type 2 diabetes tend to develop the disease at a younger age and manifest with higher glycaemia, dyslipidaemia, nephropathy, and cardiovascular diseases. Additionally, specific issues that can affect treatment of type 2 diabetes in south Asia include poor awareness of the disease, delay in diagnosis, inadequate treatment, the use of ineffective and often harmful alternative medicines, and frequent non-compliance with lifestyle recommendations and drug treatment. Disease development at younger ages, delayed diagnosis, and inadequate management result in early development of severe complications and premature mortality. In this Series paper, we describe the challenges associated with the increasing burden of type 2 diabetes in south Asia and discuss ways to improve clinical care of people with the disorder in the region (defined to include Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka). Treatment of diabetes in south Asia needs to be individualised on the basis of diverse and heterogeneous lifestyle, phenotype, environmental, social, cultural, and economic factors. Aggressive management of risk factors from diagnosis is necessary to reduce the risk of microvascular and macrovascular complications, focusing on provision of basic treatments (eg, metformin, low-cost statins, and blood pressure-lowering drugs) and other interventions such as smoking cessation. Strengthening of the primary care model of care, better referral linkages, and implementation of rehabilitation services to care for patients with chronic complications will be important. Finally, improvement of physicians' skills, provision of relevant training to non-physician health-care workers, and the development and regular updating of national clinical management guidelines will also be crucial to improve diabetes care in the region. PMID- 30287104 TI - Public health and health systems: implications for the prevention and management of type 2 diabetes in south Asia. AB - Many non-communicable chronic diseases, including type 2 diabetes, are highly prevalent, costly, and largely preventable. The prevention and management of type 2 diabetes in south Asia requires a combination of lifestyle changes and long term health-care management. However, public health and health-care systems in south Asian countries face serious challenges, including the need to provide services to many people with inadequate resources, and substantial between population and within-population inequalities. In this Series paper, we explore the importance and particular challenges of public health and health systems in south Asian countries (Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka) with respect to the provision of culturally appropriate lifestyle modification to prevent and manage diabetes, especially in resource-poor settings. Effective primary prevention strategies are urgently needed to counter risk factors and behaviours preconception, in utero, in infancy, and during childhood and adolescence. A concerted focus on education, training, and capacity building at the community level would ensure the more widespread use of non-physician care, including community health workers. Major investment from governments and other sources will be essential to achieve substantial improvements in the prevention and management of type 2 diabetes in the region.

AB - Temporomandibular disorders are painful conditions that require precise injection therapy in selected patients. This pilot cadaveric study was undertaken to compare the accuracy of temporomandibular joint (TMJ) injection between the anatomical landmark-based (blind) technique and an ultrasound-guided technique. TMJ injections using the blind technique or the ultrasound-guided technique were performed in 10 non-embalmed cadavers. After dissection, the accuracy of the TMJ injections was found to be significantly greater for the ultrasound-guided injections than for the blind technique (blind 55% vs. ultrasound 95%, P=0.008). For injections into the upper joint space of the TMJ, the success rate of the injection was comparable for the two techniques (blind 80% vs. ultrasound 100%, P=0.474). However, ultrasound-guided injections into the lower joint space had a much higher success rate than the blind technique (blind 30% vs. ultrasound 90%, P=0.020). The blind technique was associated with a considerable proportion of failed or inappropriate injections, especially for lower joint space injections. Ultrasound-guided TMJ injections were accomplished with a higher accuracy than the conventional blind technique, especially in the case of injections targeting the lower joint space of the TMJ. PMID- 30287107 TI - Direct percutaneous puncture digital-subtraction-angiography-based classification and treatment selection for soft-tissue arteriovenous malformations of maxillofacial region: a retrospective study. AB - Treatment of arteriovenous malformations (AVMs) should be individualized based on the imaging findings. A total of 117 AVM cases were categorized into three types based on the angio-architectural characteristics: Type I (n=14, no draining vein or diameter of the draining vein <2mm); Type II (n=64, draining vein diameter 2 6mm); and Type III (n=39, draining vein diameter >6mm). Subjects were randomly allocated to one of two treatment groups: Group A (n=59) received multipoint percutaneous ethanol injection (MPEI), while Group B (n=58) received super selective angiograms followed by embolization with gelfoam (EFAG) plus MPEI. Patients were followed up for 2-6 years. A significant between-group difference with respect to treatment outcomes was observed only for Type III cases (P<0.05). Direct percutaneous puncture digital-subtraction-angiography-guided classification of AVMs provides easy-to-follow guidelines for its clinical management. EFAG plus MPEI with reduced procedure time and the amount of ethanol should be used for Type III AVMs. PMID- 30287108 TI - "Feeling confident and equipped": Evaluating the acceptability and efficacy of an overdose response and naloxone administration intervention to service industry employees in New York City. AB - BACKGROUND: The problem of injection drug use in public bathrooms has been documented from the perspectives of people who inject drugs and service industry employees (SIEs). Previous studies suggest that SIEs are unaware of how to respond to opioid overdoses, yet there are no behavioral interventions designed for SIEs to address their specific needs. In response to this gap in the field, we constructed, implemented, and evaluated a three-module behavioral intervention for SIEs grounded in the Information-Motivation-Behavioral skills model. This paper focuses on the evaluation of one module, namely, the intervention component addressing overdose response and naloxone administration (ORNA). METHODS: Participants were SIEs (N = 18 from two separate business establishments) recruited using convenience sampling. The study utilized a pre-/post-test concurrent nested mixed method design and collected quantitative and qualitative data including an evaluation of the intervention module. The primary outcomes were opioid overdose-related knowledge and attitudes. Acceptability was also assessed. RESULTS: SIEs demonstrated significant improvements (p < 0.01, Cohen's d = 1.45) in opioid overdose-related knowledge as well as more positive opioid overdose-related attitudes (p< 0.01, Cohen's d = 2.45) following the intervention. Participants also reported high levels of acceptability of the module and suggestions for improvement (i.e., more role-playing). CONCLUSIONS: This study highlights the acceptability and evidence of efficacy of the ORNA module, as well as the utility of training SIEs in ORNA. The expansion of this training to other SIEs and public employees (librarians, etc.) who manage public bathrooms warrants further investigation. PMID- 30287109 TI - [Evaluation of surgical practice in the treatment of lung cancer in France from the PMSI national database]. AB - BACKGROUND: In recent years, improving the quality of care has been a concern for health professionals in France, through the certification of institutions, accreditation and continuous professional development. Evaluation of these different measures has rarely been carried out. The objective of the study was to evaluate the quality of surgical management of lung cancer in different regions using hospital mortality as an indicator. METHOD: From the national database of the Program of Medical Information Systems (PMSI), data on all patients who had undergone surgery for lung cancer were extracted as well as the characteristics of the centers. The main outcome criterion was hospital mortality. Logistic models allowed an estimation of the risk standardized mortality rate for each center. RESULTS: From January 1, 2015 to December 31, 2015, 10,675 patients underwent surgery for lung cancer in 158 French centers. The hospital mortality rate was 3.43% (n=366). Thirty-nine facilities (25%) performed fewer than 15 pulmonary resections. The minimum activity volume was a single pulmonary resection during the year and the maximum was 300 interventions with a coefficient of variation estimated at 147%. Hospital mortality ranged from 0 % to 50% depending on the entries with a coefficient of variation of 112%. For some regions, it is possible to count up to 5 centers per million inhabitants (Languedoc-Roussillon) or 4 centers per million inhabitants (Limousin, Pays-de Loire). The majority of regions had 3 centers per million inhabitants. Eleven regions have no centers with a standardized mortality rate below 3%. Five regions (Languedoc-Roussillon, Pays-de-Loire, Aquitaine, Brittany and Provence Alpes Cote d'Azur) have at least two centers with a risk standardized rate of mortality above 4%. Among the academic centers, 20% have a risk standardized mortality rate of less than 3%. Among the centers with a risk standardized rate of mortality<3%, 20% performed more than 39 pulmonary resections, 7% between 39 and 15 procedures and 0% for centers with<15 interventions. CONCLUSION: This work confirms that hospital volume is one of the components of quality of care. The number of centers should be adapted to the actual needs of the population in order to enable patients to access effective services. PMID- 30287111 TI - Internal Tensile Force and A2 Domain Unfolding of von Willebrand Factor Multimers in Shear Flow. AB - Using Brownian molecular dynamics simulations, we examine the internal dynamics and biomechanical response of von Willebrand factor (vWF) multimers subject to shear flow. The coarse grain multimer description employed here is based on a monomer model in which the A2 domain of vWF is explicitly represented by a nonlinear elastic spring whose mechanical response was fit to experimental force/extension data from vWF monomers. This permits examination of the dynamic behavior of hydrodynamic forces acting on A2 domains as a function of shear rate and multimer length, as well as position of an A2 domain along the multimer contour. Force/position data reveal that collapsed multimers exhibit a force distribution with two peaks, one near each end of the chain; unraveled multimers, however, show a single peak in A2 domain force near the center of multimers. Guided further by experimental data, significant excursions of force acting on a domain are associated with an increasing probability for A2 domain unfolding. Our results suggest that the threshold shear rate required to induce A2 domain unfolding is inversely proportional to multimer length. By examining data for the duration and location of significant force excursions, convincing evidence is advanced that unfolding of A2 domains, and therefore scission of vWF multimers by the size-regulating blood enzyme ADAMTS13, happen preferentially near the center of unraveled multimers. PMID- 30287110 TI - The Role of Lipid Interactions in Simulations of the alpha-Hemolysin Ion-Channel Forming Toxin. AB - Molecular dynamics simulations were performed to describe the function of the ion channel-forming toxin alpha-hemolysin (alphaHL) in lipid membranes that were composed of either 1,2-diphytanoyl-sn-glycero-3-phospho-choline or 1-palmitoyl-2 oleoyl-sn-glycero-3-phospho-choline. The simulations highlight the importance of lipid type in maintaining alphaHL structure and function, enabling direct comparison to experiments for biosensing applications. We determined that although the two lipids studied are similar in structure, 1,2-diphytanoyl-sn glycero-3-phospho-choline membranes better match the hydrophobic thickness of alphaHL compared to 1-palmitoyl-2-oleoyl-sn-glycero-3-phospho-choline membranes. This hydrophobic match is essential to maintaining proper alignment of beta-sheet loops at the trans entrance of alphaHL, which, when disrupted, creates an additional constriction to ion flow that decreases the channel current below experimental values and creates greater variability in channel conductance. Agreement with experiments was further improved with sufficient lipid membrane equilibration and allowed the discrimination of subtle alphaHL conduction states with lipid type. Finally, we explore the effects of truncating the extramembrane cap of alphaHL and its role in maintaining proper alignment of alphaHL in the membrane and channel conductance. Our results demonstrate the essential role of lipid type and lipid-protein interactions in simulations of alphaHL and will considerably improve the interpretation of experimental data. PMID- 30287113 TI - Childhood conditions and productive aging in China. AB - We investigate the impacts of childhood conditions on productive aging in China. Productive aging is defined as engagement in working, caring, and socially productive activities (volunteering, informal helping, etc.). Two theoretical frameworks are examined: (1) the pathway model that emphasizes later life health and socioeconomic conditions are related to dis(advantages) starting from childhood, and (2) the latency model that illustrates childhood experiences directly affect productive engagement due to biomedical influences or values and preferences formed during childhood. The 2011, 2013 and 2014 China Health and Retirement Longitudinal Studies (CHARLS) were used as these data sets provide both contemporaneous and retrospective information. The analytic sample consists of 5818 respondents aged 55 and above. We conduct multilevel analyses and path models to estimate the effects of childhood conditions, including family background (hukou - household registration - status and parents' education), neighborhood cohesion, subjective health and nutrition. Individual and family contemporaneous characteristics and clustered data structure were controlled for. The results largely support a pathway model in that childhood health and nutrition affect the likelihood of productive activities in later life through their influence on cognition and disabilities in old age. Moreover, family background and neighborhood cohesion are associated with productive activities via the effects through mid-life work, later life cognition, and disabilities. Results also provide some support for the latency model through the direct effect of neighborhood cohesion on socially productive activities, highlighting the importance of values formed in early life in shaping the motivations of productive engagement in later life. To conclude, we demonstrate that better childhood health, an advantaged family background, and values of helping others instilled in childhood affect older adults' productive engagement. Policies should be put in place to reduce socioeconomic disadvantages in childhood and also to cultivate cohesive community environments. PMID- 30287112 TI - Prediction of the Closed Conformation and Insights into the Mechanism of the Membrane Enzyme LpxR. AB - Covalent modification of outer membrane lipids of Gram-negative bacteria can impact the ability of the bacterium to develop resistance to antibiotics as well as modulating the immune response of the host. The enzyme LpxR from Salmonella typhimurium is known to deacylate lipopolysaccharide molecules of the outer membrane; however, the mechanism of action is unknown. Here, we employ molecular dynamics and Monte Carlo simulations to study the conformational dynamics and substrate binding of LpxR in representative outer membrane models as well as detergent micelles. We examine the roles of conserved residues and provide an understanding of how LpxR binds its substrate. Our simulations predict that the catalytic H122 must be Nepsilon-protonated for a single water molecule to occupy the space between it and the scissile bond, with a free binding energy of -8.5 kcal mol-1. Furthermore, simulations of the protein within a micelle enable us to predict the structure of the putative "closed" protein. Our results highlight the need for including dynamics, a representative environment, and the consideration of multiple tautomeric and rotameric states of key residues in mechanistic studies; static structures alone do not tell the full story. PMID- 30287114 TI - Diverse socioeconomic processes influencing health and wellbeing across generations in deprived neighbourhoods in Malta. AB - This study contributes to the geography of health by emphasising intergenerational differences in health determinants in a Mediterranean context. Using a grounded theory approach, it aims to explore the intergenerational processes between parents and children and their impact on determinants of health and wellbeing by focusing on the neighbourhood processes, including human, social and cultural capital in their neighbourhood. Through structured in-depth interviews with parents and children coming from two deprived neighbourhoods in Malta, it was shown that what may be considered valuable and beneficial for the adults' wellbeing may be detrimental for their children. In other cases, the neighbourhood processes that are being experienced negatively by adults seem to be beneficial for the health and wellbeing of young people. Thus the neighbourhood does not influence the inhabitants of different age groups in a homogenous and consistent manner. Indeed, the experiences of adults and children, even though they belong to the same family and neighbourhood, may differ from each other. It also emerged that it is not only the parents who can influence determinants of a young person's wellbeing; children and adolescents are able to negotiate and contradict their parents' wishes and decisions in order to enjoy conditions that they find beneficial. This study therefore demonstrates how the processes related to the social determinants of health are not static but highly dynamic, even across generations. PMID- 30287115 TI - A unified ecological framework for studying effects of digital places on well being. AB - Social media has greatly expanded opportunities to study place and well-being through the availability of human expressions tagged with physical location. Such research often uses social media content to study how specific places in the offline world influence well-being without acknowledging that digital platforms (e.g., Twitter, Facebook, Youtube, Yelp) are designed in unique ways that structure certain types of interactions in online and offline worlds, which can influence place-making and well-being. To expand our understanding of the mechanisms that influence social media expressions about well-being, we describe an ecological framework of person-place interactions that asks, "at what broad levels of interaction with digital platforms and physical environments do effects on well-being manifest?" The person is at the centre of the ecological framework to recognize how people define and organize both digital and physical communities and interactions. The relevance of interactions in physical environments depends on the built and natural characteristics encountered across modes of activity (e.g., domestic, work, study). Here, social interactions are stratified into the meso-social (e.g., local social norms) and micro-social (e.g., personal conversations) levels. The relevance of interactions in digital platforms is contingent on specific hardware and software elements. Social interactions at the meso-social level include platform norms and passive use of social media, such as observing the expressions of others, whereas interactions at the micro-level include more active uses, like direct messaging. Digital platforms are accessed in a physical location, and physical locations are partly experienced through online interactions; therefore, interactions between these environments are also acknowledged. We conclude by discussing the strengths and limitations of applying the framework to studies of place and well-being. PMID- 30287116 TI - Surgical treatments for a case of superior canal dehiscence syndrome associated with patulous Eustachian tube. AB - OBJECTIVES: The patulous Eustachian tube (PET) and superior semicircular canal dehiscence syndrome (SCDS) have similarity in their symptoms and similar effects caused by positional changes, causing difficulty in the differentiation between the two disorders. This report describes a case of both SCDS and PET that was eventually successfully treated. METHODS: A 68-year-old man presented with hyperacusis to his own footsteps and gait disturbance. He had been diagnosed as PET two years before and had been treated by insertion of a silicone plug (Kobayashi plug) at the other hospital. Clinical case records, audiological data, cervical vestibular-evoked myogenic potential (cVEMP), Eustachian tube function tests and computed tomography (CT) were taken in the sitting position. RESULTS: While the CT confirmed superior semicircular canal dehiscence, the results of cVEMP was not typical of SCD likely due to preexisting hearing impairment in the right ear with a history of middle ear surgeries for the treatment of PET. He received round window reinforcement (RWR) and achieved relief from his symptoms but six months after the surgery, he visited again with complaints of autophony of his own voice and breathing. The tympanic membrane was found to move synchronous with respiration, and Eustachian tube function tests and the sitting CT confirmed the recurrence of severe PET. He had his silicone plug exchanged (increase in size of the Kobayashi plug) and achieved relief from symptoms. CONCLUSIONS: The present case was a rare instance showing that PET and SCDS can occur simultaneously in a patient.

AB - OBJECTIVE: To evaluate the outcomes of simultaneous bilateral inlay butterfly cartilage tympanoplasties (BIBCT) using tragal cartilage from one ear in patients with bilateral chronic otitis media (BCOM). METHODS: 33 patients (66 ears) who underwent bilateral inlay butterfly cartilage tympanoplasties between June 2013 and September 2016 in Department of Otolaryngology-Head and Neck Surgery of Adiyaman University Education and Research Hospital, Adiyaman, Turkey - a tertiary care university teaching hospital. Anatomical success and functional success were assessed postoperatively. Air-bone gap (ABG), air-conduction thresholds, and bone-conduction thresholds were all assessed. The preoperative and postoperative averages of 0.5, 1, 2, and 3kHz of pure-tone thresholds were used for the mean air- and bone-conduction thresholds according to the guidelines of the Committee on Hearing and Equilibrium. RESULTS: Anatomical success could be demonstrated in 57 of 66 ears (86.3%). The overall mean of ABG improved from 23.97+/-8.63dB preoperatively to 10.42+/-4.82dB postoperatively (p<0.05). The ABG gain was 13.55+/-8.17dB. Postoperative percentages of patients with ABG less than 20dB and 10dB were excellently achieved to 98% (41% preoperatively) and 56% (10.6% preoperatively), respectively. The average length of operation time for both ears was 57.42+/-9.39min. CONCLUSION: When compared with conventional two staged tympanoplasty in patients with BCOM, simultaneous BIBCT using tragal cartilage from one ear is an advantageous approach for multiple reasons which include single hospital stay with resultant decreased risk of complications associated with anesthesia and surgery, less morbidity like cosmetic and hearing discomfort, time-savingness and cost-effectiveness. PMID- 30287118 TI - Multiple inputs into a posterior-specific regulatory network in the Ciona notochord. AB - The gene regulatory networks underlying Ciona notochord fate specification and differentiation have been extensively investigated, but the regulatory basis for regionalized expression within the notochord is not understood. Here we identify three notochord-expressed genes, C11.331, C12.115 and C8.891, with strongly enriched expression in the secondary notochord cells at the posterior tip of the tail. C11.331 and C12.115 share a distinctive expression pattern that is highly enriched in the secondary notochord lineage but also graded within that lineage with the strongest expression at the posterior tip. Both genes show similar responses to pharmacological perturbations of Wnt and FGF signaling, consistent with an important role for Wnt and FGF ligands expressed at the tail tip. Reporter analysis indicates that the C11.331 cis-regulatory regions are extensively distributed, with multiple non-overlapping regions conferring posterior notochord-enriched expression. Fine-scale analysis of a minimal cis regulatory module identifies discrete positive and negative elements including a strong silencer. Truncation of the silencer region leads to increased expression in the primary notochord, indicating that C11.331 expression is influenced by putative regulators of primary versus secondary notochord fate. The minimal CRM contains predicted ETS, GATA, LMX and Myb sites, all of which lead to reduced expression in secondary notochord when mutated. These results show that the posterior-enriched notochord expression of C11.331 depends on multiple inputs, including Wnt and FGF signals from the tip of the tail, multiple notochord specific regulators, and yet-to-be identified regulators of regional identity within the notochord.

AB - BACKGROUND: People with epilepsy (PWE) are frequently unable to recall the core manifestation of their disease, epileptic seizures. This limits their understanding of disease severity and social reactions to it. PURPOSE: The purpose of this study was to assess the effects of video presentation (VP) of one's own seizure and the role of seizure type/severity. METHODS: Ninety patients diagnosed with focal epilepsy undergoing diagnostic video-electroencephalography (EEG) monitoring were included. All participants were presented with a seizure of their predominant seizure type on videotape. Effects of viewing seizures were assessed using a questionnaire immediately after the VP (T1), after 3 days (T2), and after 3 months (T3). RESULTS: Of the participants, 97.6%, 87.2%, and 85.2% considered VP as helpful at T1, T2, and T3, respectively. Participants who viewed a more severe seizure tended to assess the VP as more helpful, related to an improved understanding of the disease and of reaction of others to their seizures. Of the participants, 11.5% and 5.0% perceived the VP as stressful at T2 and T3, respectively. Severity of the presented seizure was positively correlated to the level of stress induced, mostly because of a feeling of helplessness based on ictal loss of control. CONCLUSIONS: The VP of the patients' own seizures is a way to improve the patients' knowledge on their disease, which was appreciated by the vast majority of participants. The VP of severe seizures was regarded more informative yet also more stressful. Further research is needed to examine possible effects on quality of life and compliance. PMID- 30287121 TI - Pneumothorax and Hemothorax in the Era of Frequent Chest Computed Tomography for the Evaluation of Adult Patients With Blunt Trauma. AB - STUDY OBJECTIVE: Although traditional teachings in regard to pneumothorax and hemothorax generally recommend chest tube placement and hospital admission, the increasing use of chest computed tomography (CT) in blunt trauma evaluation may detect more minor pneumothorax and hemothorax that might indicate a need to modify these traditional practices. We determine the incidence of pneumothorax and hemothorax observed on CT only and the incidence of isolated pneumothorax and hemothorax (pneumothorax and hemothorax occurring without other thoracic injuries), and describe the clinical implications of these injuries. METHODS: This was a planned secondary analysis of 2 prospective, observational studies of adult patients with blunt trauma, NEXUS Chest (January 2009 to December 2012) and NEXUS Chest CT (August 2011 to May 2014), set in 10 Level I US trauma centers. Participants' inclusion criteria were older than 14 years, presentation to the emergency department (ED) within 6 hours of blunt trauma, and receipt of chest imaging (chest radiograph, chest CT, or both) during their ED evaluation. Exposure(s) (for observational studies) were that patients had trauma and chest imaging. Primary measures and outcomes included the incidence of pneumothorax and hemothorax observed on CT only versus on both chest radiograph and chest CT, the incidence of isolated pneumothorax and hemothorax (pneumothorax and hemothorax occurring without other thoracic injuries), and admission rates, hospital length of stay, mortality, and frequency of chest tube placement for these injuries. RESULTS: Of 21,382 enrolled subjects, 1,064 (5%) had a pneumothorax and 384 (1.8%) had a hemothorax. Of the 8,661 patients who received both a chest radiograph and a chest CT, 910 (10.5%) had a pneumothorax, with 609 (67%) observed on CT only; 319 (3.7%) had a hemothorax, with 254 (80%) observed on CT only. Of 1,117 patients with pneumothorax, hemothorax, or both, 108 (10%) had isolated pneumothorax or hemothorax. Patients with pneumothorax observed on CT only had a lower chest tube placement rate (30% versus 65%; difference in proportions [Delta] -35%; 95% confidence interval [CI] -28% to 42%), admission rate (94% versus 99%; Delta 5%; 95% CI 3% to 8%), and median length of stay (5 versus 6 days; difference 1 day; 95% CI 0 to 2 days) but similar mortality compared with patients with pneumothorax observed on chest radiograph and CT. Patients with hemothorax observed on CT had only a lower chest tube placement rate (49% versus 68%; Delta -19%; 95% CI -31% to -5%) but similar admission rate, mortality, and median length of stay compared with patients with hemothorax observed on chest radiograph and CT. Compared with patients with other thoracic injury, those with isolated pneumothorax or hemothorax had a lower chest tube placement rate (20% versus 43%; Delta -22%; 95% CI -30% to -13%), median length of stay (4 versus 5 days; difference -1 day; 95% CI -3 to 1 days), and admission rate (44% versus 97%; Delta -53%; 95% CI -62% to -43%), with an admission rate comparable to that of patients without pneumothorax or hemothorax (49%). CONCLUSION: Under current imaging protocols for adult blunt trauma evaluation, most pneumothoraces and hemothoraces are observed on CT only and few occur as isolated thoracic injury. The clinical implications (admission rates and frequency of chest tube placement) of pneumothorax and hemothorax observed on CT only and isolated pneumothorax or hemothorax are lower than those of patients with pneumothorax and hemothorax observed on chest radiograph and CT and of those who have other thoracic injury, respectively. PMID- 30287122 TI - Waterfalls and Handoffs: A Novel Physician Staffing Model to Decrease Handoffs in a Pediatric Emergency Department. AB - STUDY OBJECTIVE: Patient handoffs at shift change in the emergency department (ED) are a well-known risk point for patient safety. Numerous methods have been implemented and studied to improve the quality of handoffs to mitigate this risk. However, few have investigated processes designed to decrease the number of handoffs. Our objective is to evaluate a novel attending physician staffing model in an academic pediatric ED that was designed to decrease patient handoffs. METHODS: A multidisciplinary team met in August 2012 to redesign the attending physician staffing model. The team sought to decrease patient handoffs, optimize provider efficiency, and balance workload without increasing total attending physician hours. The original model required multiple handoffs at shift change. This was replaced with overlapping "waterfall" shifts. This was a retrospective quality improvement study of a process change that evaluated the percentage of intradepartmental handoffs before and after implementation of a new novel attending physician staffing model. In addition, surveys were conducted among attending physicians and charge nurses to inquire about perceived impacts of the change. RESULTS: A total of 43,835 patient encounters were analyzed. Immediately after implementation of the new model, there was a 25% reduction in the proportion of encounters with patient handoffs, from 7.9% to 5.9%. A survey of physicians and charge nurses demonstrated improved perceptions of patient safety, ED flow, and job satisfaction. CONCLUSION: This new emergency physician staffing model with overlapping shifts decreased the proportion of patient handoffs. This innovative system can be implemented and scaled to suit EDs that have more than single-physician coverage. PMID- 30287123 TI - The association between subclinical inflammation and abnormal glucose and lipid metabolisms in normal-weight Korean individuals. AB - BACKGROUNDS AND AIMS: We aimed to reveal the association between subclinical inflammation and metabolic risk factors and to determine the difference in the association between normal-weight and obese Korean individuals. METHODS AND RESULTS: Data collected from the Korean National Health and Nutrition Examination Survey (KNHANES) 2015, conducted from January to December 2015, were analyzed. Overall, 4620 subjects were examined and divided into two subgroups: 2987 and 1633 subjects in the normal-weight and obese groups, respectively. The prevalence of obesity in the study population was 34.5% (n = 1633). After multivariate adjustment, impaired fasting glucose (IFG) (odds ratio [OR] 1.22, 95% confidence interval [CI] 1.05-1.42, P = 0.010), high triglyceride (TG) levels (OR 1.29, 95% CI 1.13-1.47, P < 0.001), and low high-density lipoprotein-cholesterol (HDL-C) levels (OR 1.47, 95% CI 1.31-1.64, P < 0.001) were significantly associated with increased high-sensitivity C-reactive protein (hs-CRP) levels in the normal weight group but not in the obesity group. CONCLUSION: Subclinical inflammation was associated with IFG, high TG levels, and low HDL-C levels in normal-weight Korean individuals. Prospective and biochemical research is necessary to clarify the role of subclinical systemic inflammation in individuals with normal body weight and its impact on insulin resistance and abnormal lipid metabolism, which promote the incidence of metabolic syndrome and cardiovascular disease. PMID- 30287124 TI - A J-shaped relation of BMI and stroke: Systematic review and dose-response meta analysis of 4.43 million participants. AB - BACKGROUND AND AIM: Many studies have shown increased risk of stroke with greater adiposity as measured by body mass index (BMI), but questions remain about the shape of the dose-response relation. We conducted a systematic review and meta analysis of prospective studies to clarify the strength and shape of the dose response relation between BMI and risk of stroke. METHODS AND RESULTS: PubMed and Embase databases were searched for articles published up to May 11, 2018. Random effects generalized least-squares regression models were used to estimate study specific dose-response association, and restricted cubic splines were used to model the association. We included reports of 44 prospective cohort studies describing 102 466 incident cases among 4 432 475 participants. With a 5-unit increment in BMI, the summary relative risk for stroke incidence was 1.10 (95% confidence interval, 1.06 to 1.13; I2 = 88.0%). The dose-response relation was J shaped (Pnon-linearity <0.001). The risk was not increased at the low BMI range (<24 kg/m2), but was increased within the high BMI range (>25 kg/m2). CONCLUSION: Both overweight and obesity increase the risk of stroke with a J-shaped dose response relation, and the nadir of the curve was observed at BMI 23-24 kg/m2.

PMID- 30287128 TI - Comparison of ultrasonography and computed tomography in the determination of traumatic thoracic injuries. AB - OBJECTIVE: In this study, the accuracy of bedside thoracic ultrasonography (TUSG) performed by emergency physicians with patients in the supine position was compared with that of thoracic computed tomography (TCT) for the determination of thoracic injuries due to trauma. METHODS: Patients who suffered the multiple traumas, whose thoracic trauma was identified on physical examination or TCT imaging were included in the study. TUSG was performed following a physical examination by the emergency physician who managed the trauma patient. Subcutaneous emphysema, pneumothorax, pulmonary contusions (PCs), hemothorax, pericardial effusion and tamponade, sternal and clavicular fractures and rib fractures were identified by TUSG. TCT imaging was performed after the ultrasonography examination was completed. RESULTS: Eighty-one patients were included in the study. TCT scans showed subcutaneous emphysema in 16 (19.8%) patients, pneumothorax in 21 (25.9%), PCs in 27 (33.3%), hemothorax in 20 (24.7%), sternum and clavicular fractures in 6 (7.4%) and rib fractures in 21 (25.9%). The sensitivity and specificity of ultrasonography varied for detecting the following pathologies: subcutaneous emphysema (56% and 95%), pneumothorax (86% and 97%), hemothorax (45% and 98%), PCs (63% and 91%), sternal fractures (83% and 97%), clavicular fractures (83% and 100%) and rib fractures (67% and 98%), respectively. CONCLUSION: In conclusion, ultrasound was found to be highly specific but only moderately sensitive for the identification of thoracic injuries. PMID- 30287129 TI - Assessment of proadrenomedullin as diagnostic or prognostic biomarker of acute appendicitis in children with acute abdominal pain. AB - BACKGROUND: Acute appendicitis (AA) is one of the most frequent surgical pathologies in pediatrics. OBJECTIVES: To investigate the utility of proadrenomedullin (pro-ADM) for the diagnosis of AA. METHODS: Prospective, analytical, observational, and multicenter study conducted in 6 pediatric emergency departments. Children up to 18 years of age with suspected AA were included. Clinical, epidemiological, and analytical data were collected. RESULTS: We studied 285 children with an average age of 9.5 years (95% confidence interval [CI], 9.1-9.9). AA was diagnosed in 103 children (36.1%), with complications in 10 of them (9.7%). The mean concentration of pro-ADM (nmol/L) was higher in children with AA (0.51 nmol/L, SD 0.16) than in children with acute abdominal pain (AAP) of another etiology (0.44 nmol/L, SD 0.14; p < 0.001). This difference was greater in complicated cases compared with uncomplicated AA (0.64 nmol/L, SD 0.17 and 0.50 nmol/L, SD 0.15, respectively; p = 0.005). The areas under the receiver-operating characteristic curves were 0.66 (95% CI, 0.59-0.72) for pro ADM, 0.70 (95% CI, 0.63-0.76) for C-reactive protein (CRP), 0.84 (95% CI, 0.79 0.89) for neutrophils, and 0.84 (95% CI, 0.79-0.89) for total leukocytes. The most reliable combination to rule out AA was CRP <=1.25 mg/dL and pro-ADM <=0.35 nmol/L with a sensitivity of 96% and a negative predictive value of 93%. CONCLUSION: Children with AA presented higher pro-ADM values than children with AAP of other etiologies, especially in cases of complicated AA. The combination of low values of pro-ADM and CRP can help to select children with low risk of AA. PMID- 30287130 TI - Round opacity as a presentation of pneumocystis jirovecii pneumonia in an HIV infected patient. AB - We present the case of a human immunodeficiency virus (HIV)-infected patient who arrived at our emergency department with fever, headache and exertional dyspnea. Throughout their stay, a chest x-ray was taken and a rounded opacity in his left lung was observed. CT images showed same abnormality and also ground glass opacities were seen. Symptoms and images strongly suggested a pulmonary infection due to pneumocystis jirovecii, however a presence of a round lesion should always lead to neoplasia being suspected. We empirically started treatment based on trimethoprim and sulfamethoxazole. Once available, flexible bronchoscopy and bronchoalveolar lavage was performed and stained preparations from his respiratory specimens confirmed the diagnosis of pulmonary pneumocystis infection. Finally, after 4 days of antibiotic therapy, an important clinical improvement was documented; a new chest x-ray was performed and the previous rounded opacity was absent. This finding strongly suggested a case of round pneumonia. PMID- 30287125 TI - Use of quantitative molecular diagnostic methods to investigate the effect of enteropathogen infections on linear growth in children in low-resource settings: longitudinal analysis of results from the MAL-ED cohort study. AB - BACKGROUND: Enteropathogen infections in early childhood not only cause diarrhoea but contribute to poor growth. We used molecular diagnostics to assess whether particular enteropathogens were associated with linear growth across seven low resource settings. METHODS: We used quantitative PCR to detect 29 enteropathogens in diarrhoeal and non-diarrhoeal stools collected from children in the first 2 years of life obtained during the Etiology, Risk Factors, and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) multisite cohort study. Length was measured monthly. We estimated associations between aetiology-specific diarrhoea and subclinical enteropathogen infection and quantity and attained length in 3 month intervals, at age 2 and 5 years, and used a longitudinal model to account for temporality and time-dependent confounding. FINDINGS: Among 1469 children who completed 2 year follow-up, 35 622 stool samples were tested and yielded valid results. Diarrhoeal episodes attributed to bacteria and parasites, but not viruses, were associated with small decreases in length after 3 months and at age 2 years. Substantial decrements in length at 2 years were associated with subclinical, non diarrhoeal, infection with Shigella (length-for-age Z score [LAZ] reduction 0.14, 95% CI -0.27 to -0.01), enteroaggregative Escherichia coli (-0.21, -0.37 to -0.05), Campylobacter (-0.17, -0.32 to -0.01), and Giardia (-0.17, -0.30 to 0.05). Norovirus, Cryptosporidium, typical enteropathogenic E coli, and Enterocytozoon bieneusi were also associated with small decrements in LAZ. Shigella and E bieneusi were associated with the largest decreases in LAZ per log increase in quantity per g of stool (-0.13 LAZ, 95% CI -0.22 to -0.03 for Shigella; -0.14, -0.26 to -0.02 for E bieneusi). Based on these models, interventions that successfully decrease exposure to Shigella, enteroaggregative E coli, Campylobacter, and Giardia could increase mean length of children by 0.12 0.37 LAZ (0.4-1.2 cm) at the MAL-ED sites. INTERPRETATION: Subclinical infection and quantity of pathogens, particularly Shigella, enteroaggregative E coli, Campylobacter, and Giardia, had a substantial negative association with linear growth, which was sustained during the first 2 years of life, and in some cases, to 5 years. Successfully reducing exposure to certain pathogens might reduce global stunting. FUNDING: Bill & Melinda Gates Foundation.

PMID- 30287132 TI - Social Support and Its Effects on Adolescent Sexual Risk Taking: A Look at Vulnerable Populations in Baltimore and Johannesburg. AB - INTRODUCTION: We seek to understand whether and how much social support affects adolescent sexual risk-taking in disadvantaged urban environments. METHODS: Secondary analyses were conducted on data from the global Wellbeing of Adolescents (15-19years old) in Vulnerable Environments study. The outcomes of interest were sexual experience, age at sexual debut, number of lifetime sexual partners, and condom use at last sex. Social support scales measuring support at home, at school, and from peers were created, as well as a measure about who raised them. Logistic and linear regressions were used to examine associations between social support and sexual risk-taking after controlling for age, schooling, and family structure. RESULTS: Higher social support was associated with adolescents taking less sexual risk but it was context- and gender-specific. Boys raised by males had lower odds of having sex (adjusted odds ratios (aORs) from .15 (CI = .05-.42) to .19 (.04-.88)). Baltimore girls raised by grandmothers had lower odds of having sex (aOR .34 (.16-.71)). Female support at home was positively associated with girls in Baltimore (aOR .08 (CI = .04-.17)) and Johannesburg (aOR .17 (CI = .03-.87)) having fewer partners. Baltimore girls raised by fathers (aOR 3.78 (CI = 2.33-6.12)) and Johannesburg boys raised by non biological/step caregivers (aORs from 3.89 (CI = 1.12-13.44) to 8.85 (CI = 6.02 12.99)) were more likely to use condoms. CONCLUSION: Young men without male support and young women lacking parental support are at particular risk of sexual risk-taking in disadvantaged communities. Parental support can be affected by other contextual factors. Violence in neighborhoods and at home should be considered. PMID- 30287133 TI - Reciprocal Associations Between Adolescent Girls' Chronic Interpersonal Stress and Nonsuicidal Self-Injury: A Multi-wave Prospective Investigation. AB - PURPOSE: Nonsuicidal self-injury (NSSI) is associated with increased risk of suicide attempts. Theories of NSSI assert interpersonal stress as a common risk factor for, and perhaps consequence of, NSSI. Prior research has not examined reciprocal associations between chronic interpersonal stress and NSSI. This study used a multiwave, prospective design to address this gap in a sample of adolescent girls, a group with elevated risk for both chronic interpersonal stress and NSSI. Pubertal development was examined as a moderator of the reciprocal associations. METHODS: Adolescent girls (N = 220; ages 12-16, M age = 14.69 years) at heightened risk for NSSI completed a baseline assessment and follow-up assessments over 18 months, divided into two 9-month epochs (Time 1 and 2). Pubertal development was assessed via self- and parent-report. Chronic interpersonal stress was assessed using a semistructured interview at the end of each time period. NSSI was measured using a semistructured clinical interview every 3 months within both time periods to enhance accurate reporting. RESULTS: Path models revealed that chronic romantic stress during Time 1, but not peer or parent-child stress, predicted NSSI during Time 2 among girls with more advanced pubertal development. Moreover, NSSI during Time 1 predicted higher levels of chronic romantic and parent-child stress during Time 2. CONCLUSIONS: Results revealed a reciprocal relationship between chronic romantic stress and engagement in NSSI. Further, this association may be best understood in the context of pubertal development. PMID- 30287134 TI - Refractory Hypotension Caused by Prazosin Overdose Combined With Acetaminophen and Naproxen Toxicity: A Case Report and Review of the Literature. AB - BACKGROUND: Pediatric exposure to prazosin is unusual because it is most commonly indicated for the treatment of hypertension. Prazosin's increase in popularity as a treatment for posttraumatic stress disorder makes it important for emergency physicians to be aware of how to manage potential toxic ingestion because of prazosin overdose. CASE REPORT: A 16-year-old, 76-kg female presented after ingesting 110 mg of prazosin, 209.3 g of acetaminophen, and 55 g of naproxen. She was admitted to the pediatric intensive care unit for rapidly deteriorating hypotension (lowest blood pressure 47/19 mm Hg) refractory to aggressive fluid resuscitation and infusions of epinephrine and norepinephrine each at 0.5 mcg/kg/min. Stabilization of blood pressure was eventually achieved, and associated with use of a vasopressin infusion of 0.004 units/kg/min. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Because of the increasing exposure of children to prazosin, clinicians should be aware of the pharmacology behind alpha 1 antagonist overdose and consider treatment options, such as vasopressin, when hypotension is resistant to standard fluid and catecholamine therapy. PMID- 30287127 TI - Use of quantitative molecular diagnostic methods to assess the aetiology, burden, and clinical characteristics of diarrhoea in children in low-resource settings: a reanalysis of the MAL-ED cohort study. AB - BACKGROUND: Optimum management of childhood diarrhoea in low-resource settings has been hampered by insufficient data on aetiology, burden, and associated clinical characteristics. We used quantitative diagnostic methods to reassess and refine estimates of diarrhoea aetiology from the Etiology, Risk Factors, and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) cohort study. METHODS: We re-analysed stool specimens from the multisite MAL-ED cohort study of children aged 0-2 years done at eight locations (Dhaka, Bangladesh; Vellore, India; Bhaktapur, Nepal; Naushero Feroze, Pakistan; Venda, South Africa; Haydom, Tanzania; Fortaleza, Brazil; and Loreto, Peru), which included active surveillance for diarrhoea and routine non diarrhoeal stool collection. We used quantitative PCR to test for 29 enteropathogens, calculated population-level pathogen-specific attributable burdens, derived stringent quantitative cutoffs to identify aetiology for individual episodes, and created aetiology prediction scores using clinical characteristics. FINDINGS: We analysed 6625 diarrhoeal and 30 968 non-diarrhoeal surveillance stools from 1715 children. Overall, 64.9% of diarrhoea episodes (95% CI 62.6-71.2) could be attributed to an aetiology by quantitative PCR compared with 32.8% (30.8-38.7) using the original study microbiology. Viral diarrhoea (36.4% of overall incidence, 95% CI 33.6-39.5) was more common than bacterial (25.0%, 23.4-28.4) and parasitic diarrhoea (3.5%, 3.0-5.2). Ten pathogens accounted for 95.7% of attributable diarrhoea: Shigella (26.1 attributable episodes per 100 child-years, 95% CI 23.8-29.9), sapovirus (22.8, 18.9-27.5), rotavirus (20.7, 18.8-23.0), adenovirus 40/41 (19.0, 16.8-23.0), enterotoxigenic Escherichia coli (18.8, 16.5-23.8), norovirus (15.4, 13.5-20.1), astrovirus (15.0, 12.0-19.5), Campylobacter jejuni or C coli (12.1, 8.5-17.2), Cryptosporidium (5.8, 4.3-8.3), and typical enteropathogenic E coli (5.4, 2.8 9.3). 86.2% of the attributable incidence for Shigella was non-dysenteric. A prediction score for shigellosis was more accurate (sensitivity 50.4% [95% CI 46.7-54.1], specificity 84.0% [83.0-84.9]) than current guidelines, which recommend treatment only of bloody diarrhoea to cover Shigella (sensitivity 14.5% [95% CI 12.1-17.3], specificity 96.5% [96.0-97.0]). INTERPRETATION: Quantitative molecular diagnostics improved estimates of pathogen-specific burdens of childhood diarrhoea in the community setting. Viral causes predominated, including a substantial burden of sapovirus; however, Shigella had the highest overall burden with a high incidence in the second year of life. These data could improve the management of diarrhoea in these low-resource settings. FUNDING: Bill & Melinda Gates Foundation. PMID- 30287135 TI - Not Just Another "Found Down": Concomitant Upper Arm and Gluteal Compartment Syndrome. AB - BACKGROUND: Compartment syndrome is often considered in patients with long-bone fractures and soft-tissue injuries, but is not as commonly associated with a period of unconsciousness. CASE REPORT: A 65-year-old man was brought to our emergency department (ED) because he had lost consciousness for an unknown amount of time after snorting heroin. He had severe pain in his upper right arm. Physical examination revealed right arm edema, paresthesia, tenderness, and firmness to palpation. During the ED assessment, the patient began to experience pain in his right hip to a degree exceeding examination findings. We considered compartment syndrome affecting his upper arm as well as his gluteal muscles. The patient was taken to the operating room for fasciotomy. The triceps muscle was found to be bulging out of the compartment, demonstrating advanced compartment syndrome. A posterior approach to the hip allowed the gluteal sling and the fascia to be released, eliminating tension on the gluteus medius/minimus and gluteus maximus compartments. With physical therapy, the patient regained full flexion and extension in his arm at the elbow, partial extension of his wrist, and range of motion and strength in his hip. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: If not recognized, compartment syndrome can jeopardize limb and life. It should be considered in patients experiencing inordinate pain, especially if they were found unconscious at the incident scene. Pressure-induced ischemia can impair muscle function within hours. If it is not relieved with fasciotomy, the patient can sustain irreversible functional loss.

PMID- 30287137 TI - Sleep disorders: Serious threats among kidney transplant recipients. AB - In patients with chronic kidney disease (CKD) and kidney transplant recipients who continue to have some degree of CKD, the prevalence of sleep-related disorders is very high. Common sleep disorders in both groups include insomnia, sleep-disordered breathing (SDB), restless legs syndrome (RLS), excessive daytime sleepiness (EDS), and others. Depending on the kidney graft function, some patients see sleep disorders resolve after kidney transplantation, while others continue to have persistent sleep disorders or develop new ones. Kidney transplant recipients (KTRs) are unique patients due to the presence of a single kidney, the use of immunosuppressive medications, and other comorbidities including obesity, a high risk of cardiovascular disease, malignancy, and the anxiety of losing their allograft. All of these factors contribute to the risk for sleep disorders. CKD and sleep disorders have a bidirectional relationship; that is, CKD may increase the risk of sleep disorders and sleep disorders may increase the risk of CKD. Obstructive sleep apnea (OSA) is the most common form of SDB and is known to alter renal hemodynamics. OSA leads to hypoxemia and sleeps fragmentation, which activates the sympathetic nervous system. This activates the renin-angiotensin-aldosterone system and ultimately alters cardiovascular hemodynamics. Sleep disorders may have deleterious effects on the kidney allograft and proper screening and management are important for both graft and patient survival. PMID- 30287138 TI - Objective assessment of early urinary continence by analysis and visualisation of intraoperative variables of radical robotic prostatectomies with a video editor. AB - INTRODUCTION: UI after RP is a factor that has a major impact on patients' quality of life and the associated healthcare costs. The definition of UI is very variable in the literature. Similarly, a great many predictors have been studied that affect recovery of continence after surgery, the most important of which are intraoperative. MATERIAL AND METHODS: a retrospective and observational study performed between September 2008 and March 2015. We studied intraoperative factors through visualisation using a video editor of 148 patients who underwent robot-assisted radical prostatectomy, together with other perioperative factors associated with continence, and described in the literature. We assessed continence through ICQ questionnaires, urinary loss calculated by pad count, and clinical interview in the first, third, sixth month and at one year after surgery. We defined continence as not having to use a pad or using a pad for protection socially, or an ICQ <= 7. We used binary and lineal logistic regression analysis to study the relationship between the intraoperative and perioperative variables on urinary continence measured at the first, third, sixth month and one year after the operation, and on continence stability. RESULTS: In our study, 72.9% of the patients were continent at one year after surgery with a mean continence stabilisation time at 4.3 months. In our lineal logistic regression analyses we found no significant relationship with the continence variable analysed during the first year. In the lineal logistic regression analysis we found that tension-free sutures had a direct positive effect (P<=.05) on the stability time of continence, as well as the urinary losses measured in the first month after surgery. CONCLUSION: In conclusion, we found in our study that the tension-free sutures were able to help towards early stability of continence. We found no other intraoperative predictors that influenced urinary continence. The urinary losses measured in the first month related to early recovery of continence.

AB - OBJECTIVE: Sarcomatoid urothelial bladder carcinoma comprises 3% of the tumours of the bladder and is considered one of the most aggressive tumours of the urinary tract. Our aim is to analyse the characteristics of sarcomatoid urothelial bladder carcinoma in adults, its treatments and survival. METHOD: A retrospective study performed between 2000 and 2017 of all the patients with a sarcomatoid urothelial bladder carcinoma in a single centre. We studied the anatomopathological characteristics, symptoms at time of diagnosis, treatment given and survival according to the treatment given. RESULTS: Sixteen patients were diagnosed with sarcomatoid carcinoma, 11 with no heterologous component, one with rhabdomyosarcomatous components, 2 with chondrosarcomatous components and 2 with osteosarcomatous components. The mean age was 74 years (+/-20) and 88% were smokers. The primary symptom was haematuria, and the least well-tolerated was dysuria together with hypogastric pain. Ninety-four percent of the patients had muscle layer infiltration and 18% had metastases at the time of diagnosis. Thirty seven percent of the patients were treated by radical cystectomy, thirteen percent by radical cystectomy plus adjuvant chemotherapy, and 50% were treated by palliative transurethral resection to control their symptoms. A survival curve was made with the different treatments given, which showed a mean global survival of 7 months and no statistically significant differences in terms of survival according to the treatment given. CONCLUSIONS: Sarcomatoid urothelial carcinoma is an aggressive disease, of rapid and torpid onset which occurs in patients of advanced age and smokers. There are no established treatment guidelines, and it appears that no treatment influences increased survival. Cystectomy should be evaluated as a treatment alternative for patients whose symptoms are difficult to control. The various heterologous components do not appear to influence the progression of the disease or patient survival. PMID- 30287141 TI - Dynamics of ionic liquids in poly(vinyl alcohol) porous scaffold. Low field NMR study. AB - In this study molecular dynamics of ionic liquids in poly(vinyl alcohol) scaffolds were investigated. The binary poly(vinyl alcohol) - ionic liquid (PVA IL) compound was prepared from initial solutions of water, ionic liquid (IL) and poly(vinyl alcohol) (PVA) at different concentrations. Subsequently water was evaporated under open conditions, leaving the scaffold/IL system of interest. Low field nuclear magnetic resonance (NMR) relaxation and diffusion measurements, as well as 2D T1-T2 correlated NMR experiments were performed to determine specific local and translational dynamics properties at different time scales. Data suggest that during water evaporation, partial demixing of IL from the polymeric matrix leaves the remaining solvent confined in the porous structure formed by the PVA polymer. The results show that the translational diffusion, as well as the local rotational molecular dynamics is comparable to the bulk liquid state. Moreover, in partial saturation conditions, diffusion shows enhancements relative to the bulk. PMID- 30287142 TI - CCL20, a direct-acting pro-angiogenic chemokine induced by hepatitis C virus (HCV): Potential role in HCV-related liver cancer. AB - The CCL20/CCR6 chemokine/receptor axis has previously been shown to contribute to the initiation and progression of hepatocellular carcinoma (HCC) through the recruitment of CCR6-positive leukocytes to the tumor microenvironment. In particular, high serum levels of CCL20 are reported in patients with HCC induced by the hepatitis C virus (HCV). A potential non-immune role for the CCL20/CCR6 axis in HCC development has not yet been investigated. Microarray analysis (Benkheil et al., paper submitted for publication), revealed that CCL20 is highly upregulated in hepatoma cells infected with HCV compared with non-infected hepatoma cells. To determine the role of the CCL20/CCR6 axis in HCV-related HCC, we first explored which cell populations express CCR6 in human liver tissue with chronic disease or HCC. Immunohistochemical (IHC) analysis revealed that CCR6 is present on endothelial cells (ECs) of portal blood vessels in livers with chronic HCV infection and in HCV- and alcoholic-HCC tissue. In addition, we found CCR6 to be expressed on primary macrovascular (HUVECs) and microvascular ECs (HMVEC-ds) where it co-expressed with the endothelial marker CD31. In vitro angiogenesis experiments revealed that CCL20 is a direct pro-angiogenic molecule that induces EC invasion, sprouting and migration through CCR6. Moreover, using the angiogenesis matrigel plug assay in immunodeficient NMRI-nu mice, we clearly showed that CCL20 induces blood vessel formation, by attracting CCR6-positive ECs. Finally, we demonstrated that HCV-induced CCL20 protein expression and secretion in hepatoma cells could be abolished by antiviral treatment, indicating that CCL20 expression is dependent on HCV replication. In contrast to HCV, HBV infection resulted in a decreased expression of CCL20, implying a virus-specific effect. Taken together, we identified HCV-induced CCL20 as a direct pro angiogenic factor that acts on endothelial CCR6. These results suggest that the CCL20/CCR6 axis contributes to hepatic angiogenesis, promoting the hypervascular state of HCV-HCC. PMID- 30287143 TI - LL-37 inhibits LPS-induced inflammation and stimulates the osteogenic differentiation of BMSCs via P2X7 receptor and MAPK signaling pathway. AB - Oral diseases, such as periapical periodontitis and periodontitis, are characterized by inflammation-induced bone loss. LL-37, a human antimicrobial peptide (AMP), has multiple biological functions and the potential to promote osteogenesis. Therefore, this study aimed to investigate the regulatory effects of LL-37 within normal and inflammatory microenvironments. The roles of P2X7 receptor (P2X7R) and mitogen-activated protein kinase (MAPK) signaling pathway were also demonstrated. The results showed that LL-37 promoted bone marrow stromal cell (BMSC) proliferation, migration and osteogenic differentiation. LL 37 inhibited the expression of the inflammatory cytokines interleukin-1beta (IL 1beta), tumor necrosis factor-alpha (TNF-alpha) and receptor activator of nuclear factor kappa-B ligand (RANKL) at both protein and gene levels, and attenuated the lipopolysaccharide (LPS)-induced inhibition of osteogenesis. Immunofluorescence (IF) confirmed P2X7R expression in BMSCs. BBG, a P2X7R antagonist, significantly attenuated LL-37-promoted osteogenesis. The phosphorylation of extracellular signal-regulated kinase 1/2 (ERK1/2) and c-Jun NH2-terminal kinase (JNK) increased after LL-37 stimulation, which did not affect p38 phosphorylation. The effects of LL-37 on osteogenesis-related gene expression were markedly attenuated by selective inhibitors of ERK1/2 and JNK. Furthermore, a mouse model of LPS stimulated calvarial osteolysis was established, and results showed that LL-37 markedly inhibited osteoclastic bone resorption. In conclusion, we speculate that LL-37 inhibits inflammation and promotes BMSC osteogenesis via P2X7R and MAPK signaling pathway. PMID- 30287144 TI - Efficacy of heart failure reversal treatment followed by 90 days follow up in chronic heart failure patients with low ejection fraction. AB - BACKGROUND: Heart failure reversal therapy (HFRT) is designed to enhance cardiorespiratory fitness of chronic heart failure (CHF) patients. OBJECTIVES: The present study was designed to evaluate efficacy of HFRT that uses herbal procedure (panchakarma) and allied therapies, in CHF patients with low ejection fraction. METHODS: This efficacy study was conducted in CHF patients (aged: 25-65 years, ejection fraction (EF) 10-30%) wherein HFRT (60-75 min) consisting of snehana (external oleation), swedana (passive heat therapy), hrudaydhara (concoction dripping treatment) and basti (enema) was administered twice daily for 7 days. During this therapy and next 30 days, patients followed the study dinarcharya and were prescribed ARJ kadha in addition to their conventional treatment. The primary endpoint of this study was evaluation of maximum aerobic capacity uptake (MAC) as assessed by 6 min walk distance (6MWD) using Cahalins equation from baseline, at the end of 7 day treatment, follow-up after 30 days and 90 days. EF was assessed by 2D Echo at baseline and after 30 days of follow up. RESULTS: Fifty-two CHF patients with 10-30% EF (mean [SD] age: 58.8 [10.8], 85% men) were enrolled in the study. There was a 100% compliance to study therapy. A significant improvement was observed in MAC levels (7.11%, p = 0.029), at the end of 7 day therapy as compared to baseline. This improvement was maintained at two follow-up visits. Moreover ejection fraction was observed to be increased by 6.38%, p = 0.012 as compared to baseline at day 7 of the therapy. CONCLUSION: This 90 day follow up study highlights the benefit of HFRT, as a part of maintenance treatment for CHF patients with reduced ejection fraction. PMID- 30287140 TI - Biochemical Aspects of PD-L1 Regulation in Cancer Immunotherapy. AB - PD-L1, frequently expressed in human cancers, engages with PD-1 on immune cells and contributes to cancer immune evasion. As such, antibodies blocking the PD 1/PD-L1 interaction reactivate cytotoxic T cells to eradicate cancer cells. However, a majority of cancer patients fail to respond to PD-1/PD-L1 blockade with unclear underlying mechanism(s). Recent studies revealed that PD-L1 expression levels on tumor cells might affect the clinical response to anti-PD 1/PD-L1 therapies. Hence, understanding molecular mechanisms for controlling PD L1 expression will be important to improve the clinical response rate and efficacy of PD-1/PD-L1 blockade. In this review, we primarily focus on summarizing PD-L1 regulation and its potential roles in regulating antitumor immune response, with purpose to optimize anti-PD-1/PD-L1 therapies, benefiting a wider cancer patient population. PMID- 30287145 TI - Robustness of Textural Features to Predict Stone Fragility Across Computed Tomography Acquisition and Reconstruction Parameters. AB - RATIONALE AND OBJECTIVES: Previous studies have demonstrated that quantitative relationships exist between stone fragility at lithotripsy and morphological features extracted from computed tomography (CT) scans. The goal of this study was to determine if variations in scanner model, patient size, radiation dose, or reconstruction parameters impact the accuracy of the prediction of renal stone fragility in an in vitro model. MATERIALS AND METHODS: Sixty-seven kidney stones were scanned using routine single and dual energy stone protocols, mimicking average, and large patient habitus. Low dose scans were also performed. Each scan was reconstructed with routine protocol parameters, and with thinner (0.6 mm) or thicker (3mm) images, two different reconstruction kernels, and iterative reconstruction at two strengths. Fragilityof each stone was measured in a controlled ex vivo experiment. A single predictive model was developed from a reference CT protocol configuration and applied to data from each CT acquisition and reconstruction parameter tested to obtain estimated stone comminution times. RESULTS: None of the investigated protocols showed a significant variation in the accuracy of stone fragility classification, except for the ones with the most aggressive iterative reconstruction and/or with thicker images. In these protocols, a number of stone fragility assessments changed from fragile to hard (or vice versa), compared to their ground truth measurement. CONCLUSION: Prediction accuracy of stone fragility models developed from CT data is robust to expected variations in CT stone protocols used for quantification tasks. This finding facilitates their future adoption to different clinical practices. PMID- 30287146 TI - The reliability, validity, and methodologic quality of measurements used to quantify posterior shoulder tightness: a systematic review of the literature with meta-analysis. AB - HYPOTHESIS AND BACKGROUND: Posterior shoulder tightness (PST) has been linked to numerous shoulder pathologies in both the general and athletic populations. Several methods for documenting PST have been described in the literature, which may lend to variability in clinical practice and research. The purpose of this study was to perform a systematic review with meta-analysis to investigate the reliability, validity, and methodologic quality of methods used to quantify PST. METHODS: Relevant studies were assessed for inclusion, and selected studies were identified from the PubMed, Embase, Cochrane, and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases. Data were extracted from the selected studies and underwent methodologic quality assessment and meta-analysis. RESULTS: The search resulted in 1006 studies identified, with 18 ultimately retained. Intrarater reliability was reported in 12 studies with a summary intraclass correlation coefficient of 0.93 (95% confidence interval, 0.90-0.95), whereas inter-rater reliability was reported in 6 studies with a summary intraclass correlation coefficient of 0.89 (95% confidence interval, 0.80-0.94). Validity was reported in 10 studies, all using internal rotation as the convergent standard, and was found to be significant in all but 1 study. CONCLUSION: Current methods used to quantify PST have good reliability but are primarily limited to measures of horizontal adduction of the glenohumeral joint with scapular stabilization. Limitations in using a single measurement technique exist particularly as there may be multiple contributing factors to PST. A more comprehensive approach for quantifying PST is necessary, and suggested components include a cluster of techniques composed of horizontal adduction, internal rotation, and total glenohumeral joint range of motion. PMID- 30287147 TI - Social resource assessment: Application of a novel communication tool during hospital discharge. AB - OBJECTIVE: To evaluate an interactive tool designed to help patients communicate their social resources supportive of home recovery to health care providers. METHODS: Seventy medical and surgical inpatients completed the D-CEGRM social resource interview, demographic queries, and discharge readiness surveys (RHDS) at discharge. Two weeks later, patients completed post-discharge coping difficulty surveys (PDCDS). Nurses unassociated with patients' clinical care reviewed structured clinical notes created from the D-CEGRM and categorized patients as likely to have "inadequate" or "adequate" supportive resources for home self-management. Nurse decision making was tracked using an adjudication process, and post-hoc comparisons in patient characteristics, RHDS, and PDCDS were conducted. RESULTS: Nurses categorized 36 patients (51%) as having inadequate resources. Number and accessibility of supports, presence of negative relationships, and previous struggles meeting health-related needs were important decision-making factors. Post-hoc comparisons revealed significant differences in demographic risk factors and discharge readiness ratings for those with inadequate vs. adequate resources. CONCLUSION: The D-CEGRM may be an efficient tool for patients to communicate access to social resources, and an effective facilitator of transitional care planning. PRACTICE IMPLICATIONS: The D-CEGRM may provide a useful assessment of patients' home context and guide for transitional care planning.

PMID- 30287148 TI - The added value of therapist communication on the effect of physical therapy treatment in older adults; a systematic review and meta-analysis. AB - OBJECTIVE: Lower physical activity levels in older adults are associated with increased co-morbidities and disability. Physical therapists have a critical role in facilitating increases in physical activity. The communication they use may impact their effectiveness. This study investigates the additional value of therapist's communication during physical therapy on older adults' physical activity levels. METHODS: Systematic review and meta-analysis. Clinical trials were identified in PubMed, CINAHL, Embase, PsycINFO, PEDro, Cochrane, up to July 2016. Communication was classified with the Behavior Change Taxonomy(BCT). Effect sizes were pooled using Cochrane's Review-Manager. Strength of the evidence was analyzed using GRADE's criteria. RESULTS: Twelve studies were identified. Overall, communication techniques revealed an immediate and long-term effect(ES:0.19;0.24) on self-reported physical activity measures but not on performance-based, with moderate to high strength of evidence. Divided in BCT categories, only 'Generalisation of target behavior', defined as communication aimed to help patients generalise an exercise from one situation to another at home, had a positive effect on self-reported activity(ES:0.34), with low strength of evidence. CONCLUSION: Adding a communication technique to physical therapy is effective on self-reported physical activity measures but not on performance based measures. PRACTICE IMPLICATIONS: Add communication to exercise when treatment aims at perceived, but not performed, physical activity. PMID- 30287150 TI - Oxytocin and excitation/inhibition balance in social recognition. AB - Social recognition is the sensitive domains of complex behavior critical for identification, interpretation and storage of socially meaningful information. Social recognition develops throughout childhood and adolescent, and is affected in a wide variety of psychiatric disorders. Recently, new data appeared on the molecular mechanisms of these processes, particularly, the excitatory-inhibitory (E/I) ratio which is modified during development, and then E/I balance is established in the adult brain. While E/I imbalance has been proposed as a mechanism for schizophrenia, it also seems to be the common mechanism in autism spectrum disorder (ASD). In addition, there is a strong suggestion that the oxytocinergic system is related to GABA-mediated E/I control in the context of brain socialization. In this review, we attempt to summarize the underpinning molecular mechanisms of E/I balance and its imbalance, and related biomarkers in the brain in healthiness and pathology. In addition, because there are increasing interest on oxytocin in the social neuroscience field, we will pay intensive attention to the role of oxytocin in maintaining E/I balance from the viewpoint of its effects on improving social impairment in psychiatric diseases, especially in ASD. PMID- 30287151 TI - Vitamin D protects against diabetic nephropathy: Evidence-based effectiveness and mechanism. AB - Vitamin D has been suggested to harbor multiple biological activities, among them the potential of vitamin D in the protection of diabetic nephropathy (DN) has attracted special attention. Both animal studies and clinical trials have documented an inverse correlation between low vitamin D levels and DN risk, and supplementation with vitamin D or its active derivatives has been demonstrated to improve endothelial cell injury, reduce proteinuria, attenuate renal fibrosis, and resultantly retard DN progression. Vitamin D exerts its pharmacological effects primarily via vitamin D receptor, whose activation inhibits the renin angiotensin system, a key culprit for DN under hyperglycemia. The anti-DN benefit of vitamin D can be enhanced when administrated in combination with angiotensin converting enzyme inhibitors or angiotensin II receptor blockers. Mechanistic studies reveal that pathways relevant to inflammation participate in the pathogenesis of DN, however, consumption of vitamin D-related products negatively regulates inflammatory response at multiple levels, indicated by inhibiting macrophage infiltration, nuclear factor-kappa B (NF-kappaB) activation, and production of such inflammatory mediators as transforming growth factor-beta(TGF beta), monocyte chemoattractant protein 1(MCP-1), and regulated upon activation normal T cell expressed and secreted protein(RANTES). The robust anti inflammatory property of vitamin D-related products allows them with a promising renoprotective therapeutic option for DN. This review summarizes new advances in our understanding of vitamin D-related products in the DN management. PMID- 30287152 TI - (-)-alpha-bisabolol prevents neuronal damage and memory deficits through reduction of proinflammatory markers induced by permanent focal cerebral ischemia in mice. AB - The pathophysiology of ischemic stroke involves multiple events such as inflammation and oxidative stress which will lead to neuronal death and cognitive deficits. The (-)-alpha-bisabolol is a monocyclic sesquiterpene alcohol found in various plants and mainly in Matricaria chamomilla, which exerts antioxidant, anti-inflammatory, and anti-apoptotic activities. The aim of this work was to investigate the neuroprotective effects of (-)-alpha-bisabolol in mice underwent permanent occlusion of the middle cerebral artery (pMCAO). Animals were treated with (-)-alpha-bisabolol (50, 100 and 200 mg/kg/day, orally) or vehicle (3% tween 80) one day before and 1 h after pMCAO and the treatment continued once daily for the following five days. The treatment with (-)-alpha-bisabolol (100 and 200 mg/kg) significantly reduced the infarcted area and neurological deficits caused by pMCAO. (-)-alpha-bisabolol at the 200 mg/kg dose increased cell viability and decreased neuronal degeneration, as evaluated by cresyl violet and Fluoro-Jade C stainings, respectively. (-)-alpha-bisabolol also increased the locomotor activity which was reduced by cerebral ischemia and improved pMCAO-induced working, spatial, object recognition, and aversive memories deficits. (-)-alpha bisabolol (200 mg/kg) significantly prevented the increase of myeloperoxidase (MPO) activity, TNF-alpha immunoreactivity in the temporal cortex, and the increase of iNOS both in the temporal cortex and in the striatum. (-)-alpha bisabolol treatment also prevented astrogliosis in these areas. These data showed that (-)-alpha-bisabolol provides neuroprotective action probably due to its anti inflammatory activity, although other mechanisms cannot be discarded. PMID- 30287153 TI - Escin induces apoptosis in human bladder cancer cells: An in vitro and in vivo study. AB - Escin (beta-escin) is used as traditional folk medicine. The anti-tumour effects of escin have been demonstrated in vitro in certain cell lines, but its effect on bladder cancer has not been well investigated. In this study, the apoptotic activity of escin dissolved in dimethyl sulfoxide (DMSO) in bladder cancer cells and normal peripheral blood mononuclear cells (PBMC) and SV-HUC1 cells (controls) was determined. Cell cytotoxicity was assessed using the MTT assay. Cell cycle, Reactive oxygen species (ROS) generation, annexin V-FITC staining (for detecting early apoptosis), and changes in mitochondrial membrane potential were evaluated using flow cytometry. Expression of apoptosis-related proteins such as Fas (CD95) death receptor/FADD (Fas-associated protein with death domain) and BCL2 family of proteins was assessed using immunoblotting. Escin dose-dependently inhibited the growth of human bladder cancer cells, and showed IC50 of ~40 MUM. The cell population in the sub-G1 phase, annexin-V staining, Fas expression, ratio of BAX/BCL2, cleavage of activated caspase-3/-8/-9, increase in poly (ADP-ribose) polymerase (PARP) levels, and suppression of nuclear factor kappa B (NF-kappaB) were observed after 24 h of escin treatment. Escin decreased mitochondrial membrane potential and increased cytochrome C release via generation of reactive oxygen species, which led to apoptosis of bladder cancer cells. Furthermore, escin effectively inhibited bladder tumour growth in a xenograft mouse model. Together, these results demonstrate that escin induces apoptosis in human bladder cancer cells through the Fas death receptor and mitochondrial pathways and inhibits bladder tumour growth. Escin is a potential chemotherapeutic agent for bladder cancer. PMID- 30287154 TI - Mechanisms underlying select chemotherapeutic-agent-induced neuroinflammation and subsequent neurodegeneration. AB - This review demonstrates the importance of uncovering the mechanisms that underlie chemotherapy-induced neuroinflammation. It builds upon the well established connection between chemotherapeutic-agents and neurotoxicity along with widespread peripheral toxicities. This article summarises the major studies which have linked chemotherapy-induced neurodegeneration with direct evidence of neuroinflammation. Cancer and chemotherapy-related adverse effects impact a large proportion of the population. A better understanding of the link between chemotherapy, neurotoxicity and specifically the mechanisms of neuroinflammation, will allow the development of strategies to improve the management of side effects, and overall to reduce the burden on cancer patients receiving chemotherapy. This review has developed a summary schematic of the relationship between different chemotherapeutic agents and inflammatory markers within the central nervous system and links this correlation with some major ailments associated with chemotherapy use. PMID- 30287155 TI - N-Benzyl-N-methyl-dodecan-1-amine, a novel compound from garlic, exerts anti cancer effects on human A549 lung cancer cells overexpressing cancer upregulated gene (CUG)2. AB - Dietary garlic has been suggested to possess anticancer properties, and several attempts have been made to isolate the anticancer compounds. In this study, we efficiently synthesized N-benzyl-N-methyl-dodecan-1-amine (BMDA) by the reductive amination method. We evaluated the potential anticancer activities of BMDA against A549 lung cancer cells with cancer stem cell-like phenotypes due to the overexpression of cancer upregulated gene (CUG)2. N-Benzyl-N-methyl-dodecan-1 amine treatment sensitized A549 cells overexpressing CUG2 (A549-CUG2) to apoptosis and autophagy compared with those of the control cells. The treatment with BMDA also reduced tumor development in xenografted nude mice. Furthermore, BMDA inhibited cell migration, invasion, and sphere formation in A549-CUG2 cells, in which TGF-beta signaling is involved. Further analysis showed that BMDA hindered TGF-beta promoter activity, protein synthesis, and phosphorylation of Smad2, thus decreasing the expression of TGF-beta-targeted proteins, including Snail and Twist. N-Benzyl-N-methyl-dodecan-1-amine also decreased Twist expression in vivo. In addition, BMDA inhibited Akt-ERK activities, beta-catenin expression, and its transcriptional activity. These results suggest that BMDA can be a promising anticancer agent against cancer cells overexpressing CUG2. PMID- 30287156 TI - Epitope clustering analysis for vaccine-induced human antibodies in relationship to a panel of murine monoclonal antibodies against HPV16 viral capsid. AB - Human papillomavirus (HPV) type 16 is the most common type implicated as the etiological agent that causes cervical cancer. The marketed prophylactic vaccines against HPV infection are composed of virus-like particles (VLPs) assembled from the recombinant major capsid protein L1. Elicitation of functional and neutralizing antibodies by vaccination is the mode of action by which the vaccines prevent the viral infection. In this study, a panel of murine mAbs against HPV16 L1 were generated and comprehensively characterized with respect to their mapping to the epitope spectrum on the viral capsid. These mAbs were categorized into five epitope bins by two different methods based on the pairwise cross-inhibition and competition with human polyclonal antibodies. In addition, a preliminary demonstration of the spatial relationship of the epitopes recognized by these mAbs was performed using a cross-blocking assay with a well characterized human mAb, 26D1. Interestingly, two mAbs recognizing different epitopes were found to act synergistically in the pseudovirion-based neutralization assay (PBNA). To facilitate cross-lab and cross-study comparison, the international standard (IS) serum 05/134 was used to calibrate the mAbs as well as the human serum samples from the HPV16/18 vaccine recipients. The neutralizing mAbs, particularly those that recognizing immunodominant epitopes, would be useful in developing epitope-specific assays for monitoring the vaccine production process and for serological assessment. PMID- 30287157 TI - Assessing the effectiveness of high-dose influenza vaccine in preventing hospitalization among seniors, and observations on the limitations of effectiveness study design. AB - BACKGROUND: The availability of high-dose (HD) influenza vaccine for seniors should decrease influenza-related hospitalization. Studies to date show a range of mostly moderate increased HD vaccine effectiveness (VE). While a 'healthy vaccinee' phenomenon can inflate VE, for influenza and particularly an HD vaccine targeted at frailer adults, an 'at-risk vaccinee' bias may deflate VE estimates. We assessed senior HD vaccine effectiveness against influenza-related hospitalization by linking immunization registry records to hospitalizations. We also examined whether adding strata typically ignored in case-control matching schemas, such as residence areas, exact age, and provider biases, would increase VE. METHODS: For the 2016-17 influenza season in the Portland metropolitan area, the differential VE for the HD vaccine in preventing PCR-confirmed influenza hospitalization was assessed by a nested series of models across matching strata. For an exact match for high-dose and standard-dose seniors, matching elements included exact age, gender, residence type, race-ethnicity, provider bias, and residence area (zipcode). RESULTS: As a first step, a simple aggregate comparison of influenza-related hospitalization risk showed no added HD effectiveness. For the nested models, adding strata increased VE. In the final model, among 23,712 matched pairs of HD to SD vaccinated seniors, the HD vaccine was 30.7% (95%CI: 8 48%) more effective in preventing influenza-related hospitalization. CONCLUSION: For this study, the high-dose influenza vaccine provided superior protection for seniors against influenza hospitalization. Including matching elements as exact year of age and residence zipcode all added to the calculation of VE. As a warning, non-matched or overly simple matched VE study designs may substantially under-estimate VE. PMID- 30287159 TI - Inferior pseudo-hinge fulcrum technique and intraoperative complications of laser in situ keratomileusis retreatment after small-incision lenticule extraction. AB - PURPOSE: To describe the evolution of a flap-lift technique for laser in situ keratomileusis (LASIK) retreatment after small-incision lenticule extraction (SMILE) and report the incidence of complications. SETTING: London Vision Clinic, London, United Kingdom. DESIGN: Retrospective case series. METHODS: All retreatments between September 2013 and January 2017 were included. A bimanual inferior pseudo-hinge fulcrum flap-lift technique was developed to minimize the chance of tearing or entering the small incision. A flap lifter and a McPherson forceps were inserted into the inferior one third of the flap, slightly angled up to avoid perforating the small-incision lenticule extraction interface. One instrument provided countertraction, and the second separated the interface superiorly, keeping the tip away from the incision. One instrument was held against the hinge for the second instrument to separate the inferior one third. The incidence of intraoperative complications was analyzed. RESULTS: The study evaluated 162 retreatments (4.12%) for 3933 small-incision lenticule extraction treatments (1-year maturity). The retreatment was LASIK (n = 135), side-cut only (n = 1), cap-to-flap procedure (CIRCLE) (n = 3), or photorefractive keratectomy (n = 23). Two eyes (1.4%) had a tear to the small incision. The small-incision lenticule extraction interface was accessed in 8 eyes (5.8%), 1 (0.7%) centrally, and the interface was lifted in 1 eye (0.7%). There were no complications in the last 84 consecutive procedures (60%) using the finalized technique. CONCLUSION: The bimanual inferior pseudo-hinge fulcrum decreased the risk for accessing the small-incision lenticule extraction interface or tearing the small incision. PMID- 30287158 TI - Resting state functional connectivity in patients with remitted psychotic depression: A multi-centre STOP-PD study. AB - BACKGROUND: There is paucity of neurobiological knowledge about major depressive disorder with psychotic features ("psychotic depression"). This study addresses this knowledge gap by using resting state functional magnetic resonance imaging (R-fMRI) to compare functional connectivity in patients with psychotic depression and healthy controls. METHODS: We scanned patients who participated in a randomized controlled trial as well as healthy controls. All patients achieved remission from depressive and psychotic symptoms with sertraline and olanzapine. We employed Independent Component Analysis in independent samples to isolate the default mode network (DMN) and compared patients and controls. FINDINGS: The Toronto sample included 28 patients (mean [SD], age 56.2 [13.7]) and 39 controls (age 55.1 [13.5]). The Replication sample included 29 patients (age 56.1 [17.7]) and 36 controls (age 48.3 [17.9]). Patients in the Toronto sample demonstrated decreased between-network functional connectivity between the DMN and bilateral insular, somatosensory/motor, and auditory cortices with peak activity in the right planum polare (t = 4.831; p = 0.001, Family Wise Error (FWE) corrected). A similar pattern of between-network functional connectivity was present in our Replication sample with peak activity in the right precentral gyrus (t = 4.144; p = 0.003, FWE corrected). INTERPRETATION: Remission from psychotic depression is consistently associated with an absence of increased DMN-related functional connectivity and presence of decreased between-network functional connectivity. Future research will evaluate this abnormal DMN-related functional connectivity as a potential biomarker for treatment trajectories. FUNDING: National Institute of Mental Health.

AB - Adenine nucleotides are essential in countless processes within the cellular metabolism. In plants, ATP is mainly produced in chloroplasts and mitochondria through photophosphorylation and oxidative phosphorylation, respectively. Thus, efficient adenylate transport systems are required for intracellular energy partitioning between the cell organelles. Adenylate carriers present in different subcellular compartments have been previously identified and biochemically characterized in plants. Here, by using data-mining bioinformatics tools, we propose how, and to what extent, these carriers integrate energy metabolism within a plant cell under different environmental conditions. We demonstrate that the expression pattern of the corresponding genes is variable under different environmental conditions, suggesting that specific adenylate carriers have distinct and nonredundant functions in plants. PMID- 30287160 TI - Insulin-like Growth Factor (IGF)-1 treatment stabilizes the microvascular cytoskeleton under ischemic conditions. AB - Our previous studies showed that Insulin-like Growth Factor (IGF)-1 reduced blood brain barrier permeability and decreased infarct volume caused by middle cerebral artery occlusion (MCAo) in middle aged female rats. Similarly, cultures of primary brain microvessel endothelial cells from middle-aged female rats and exposed to stroke-like conditions (oxygen glucose deprivation; OGD) confirmed that IGF-1 reduced dye transfer across this cell monolayer. Surprisingly, IGF-1 did not attenuate endothelial cell death caused by OGD. To reconcile these findings, the present study tested the hypothesis that, at the earliest phase of ischemia, IGF-1 promotes barrier function by increasing anchorage and stabilizing cell geometry of surviving endothelial cells. Cultures of human brain microvessel endothelial cells were subject to oxygen-glucose deprivation (OGD) in the presence of IGF-1, IGF-1 + JB-1 (IGFR inhibitor) or vehicle. OGD disrupted the cell monolayer and reduced cell-cell interactions, which was preserved in IGF-1 treated cultures and reversed by concurrent treatment with JB-1. IGF-1-mediated preservation of the endothelial monolayer was reversed with LY294002 treatment, but not by Rapamycin, indicating that IGF-1 s actions on cell-cell contacts are likely mediated via the PI3K pathway. In vivo, microvessel morphology was evaluated in middle-aged female rats that were subjected to ischemia by MCAo, and treated ICV with IGFI, IGF-1 + JB-1, or artificial CSF (aCSF; vehicle) after reperfusion. Compared to vehicle controls, IGF-1 treated animals displayed larger microvessel diameters in the peri-infarct area and increased staining density for vinculin, an anchorage protein. Both these measures were reversed by concurrent IGF-1 + JB-1 treatment. Moreover these effects were restricted to 24 h after ischemia-reperfusion and no treatment effects were seen at 5d post stroke. Collectively, these data suggest that in the earliest hours during ischemia, IGF 1 promotes receptor-mediated anchorage of endothelial cells, and its actions may be accurately characterized as vasculoprotective. PMID- 30287162 TI - How Soil Biota Drive Ecosystem Stability. AB - High biodiversity aboveground tends to increase the stability of ecosystem functioning when faced with a changing environment. However, whether and how soil biota affect ecosystem stability is less clear. Here, we introduce a framework for understanding the effects of soil biota on variation in ecosystem functioning under environmental changes. We conclude that soil biota may be a neglected factor determining ecosystem stability through their direct and indirect effects on plant diversity, the net productivity of an ecosystem, and compensatory dynamics among plant species, and via altering ecosystem resistance and resilience. Furthermore, future research needs to consider that effects of soil biota on ecosystem stability will vary depending on extrinsic factors, and for a given perturbation and ecosystem function.

PMID- 30287165 TI - Bully victimization and child and adolescent health: new evidence from the 2016 NSCH. AB - PURPOSE: To explore whether children with diagnosable health conditions are at greater risk of bully victimization and whether, among these children, bully victimization further elevates the risk of an array of health difficulties. METHODS: We examined a recent, nationally representative sample of children and adolescents aged 6-17 years who participated in the 2016 National Survey of Children's Health. Survey data pertaining to the children and adolescents covering bully victimization, health difficulties, and diagnosable health conditions were obtained from primary caregivers. RESULTS: The results suggest that children with diagnosable conditions are at significantly higher risk of being bullied, particularly among children with birth defects and developmental disorders (e.g., 50% or more are victims of bullying). Furthermore, the findings reveal that, among children with diagnosable conditions, those who are victims of bullying are significantly more likely to experience various health challenges, relative to nonvictims. While these findings are significant across age groups, 12- to 17-year-old youth are more likely to experience bullying in the presence of multiple developmental disorders, and when this occurs, these youth are more likely to manifest health difficulties than younger children. CONCLUSIONS: The findings suggest that children with disabilities and chronic health conditions, who are at a significantly greater risk of being bullied, also suffer from further health difficulties when they are victimized by their peers. In conjunction with school-based interventions, primary care physicians may be ideally positioned to assess youth for victimization risk, provide counseling to youth victims, and reduce future victimization through office-based youth violence interventions.

PMID- 30287167 TI - Impact of preoperative sarcopenia on postoperative outcomes following pancreatic resection: A systematic review and meta-analysis. AB - BACKGROUND: Morphometric analysis of sarcopenia has garnered interest due to its putative role in predicting outcomes following surgery for a variety of pathologies, including resection for pancreatic disease. However, there are no standard recommendations on whether sarcopenia is a clinically relevant predictor of outcomes in this setting. The aim of this study was to review the prognostic impact of preoperatively diagnosed sarcopenia on postoperative outcomes following pancreatic resection. METHODS: A systematic review of published literature was performed using PRISMA guidelines, and included a search of PubMed, MEDLINE and SCOPUS databases until May 2018. RESULTS: Thirteen studies, including 3608 patients, were included. There was a significant increase in the mean duration of post-operative hospital stay (mean difference of 0.73 days, CI: 0.06-1.40, P = 0.033), there was no difference in the postoperative outcomes, including: clinically relevant postoperative pancreatic fistula, delayed gastric emptying, post-operative bile leak, surgical site infection, significant morbidity and overall morbidity. CONCLUSION: Preoperative sarcopenia is associated with prolonged hospital stay after pancreatic surgery. However, sarcopenia does not appear to be a significant negative predictive factor in postoperative morbidity although study heterogeneity and risk of bias limit the strength of these conclusions. PMID- 30287168 TI - Systemic chemotherapy in combination with liver-directed therapy improves survival in patients with pancreatic adenocarcinoma and synchronous liver metastases. AB - OBJECTIVES: We investigated whether the combination of systemic chemotherapy (SCT) and liver-directed therapy (LDT) was superior to chemotherapy alone for patients with pancreatic adenocarcinoma and synchronous liver metastases (PACLM). METHODS: We reviewed the medical records of 184 patients treated with SCT +/- LDT at Tianjin Medical University Cancer Hospital from 2001 to 2015. Overall survival (OS) was the primary end-point. The role of treatment modality and other clinical factors was evaluated by univariate and Cox regression analyses. RESULTS: Sixty four (34.8%) patients in the SCT-LDT group and 120 (65.2%) patients in the SCT group were included in the analysis. Baseline clinical characteristics were similar between the groups (all P > 0.05). The median survival was 8.7 months in the SCT-LDT group and was 6.3 months in the SCT group. The 0.5-, 1-, 2- and 3 year survival rates were 67.2%, 33.4%, 13.3% and 8.9%, respectively, after SCT LDT, and were 54.9%, 19.0%, 4.5% and 2.0%, respectively, after SCT (P = 0.01). Primary tumor size, ascites, and treatment modality (SCT + LDT vs. SCT) independently predicted survival (P < 0.05). The clinical efficacy congruously favored the SCT-LDT group across the majority of subgroups. CONCLUSIONS: SCT combined with LDT was well tolerated and may be effective to improve survival of patients with PACLM. Ascites and large primary tumor size were poor prognostic factors associated with survival. PMID- 30287169 TI - Genetic Factors That Affect Spontaneous Clearance of Hepatitis C or B Virus, Response to Treatment, and Disease Progression. AB - Hepatitis C virus (HCV) and hepatitis B virus (HBV) infections can lead to cirrhosis, end-stage liver disease, and hepatocellular carcinoma. Over the past decade, studies of individuals infected with these viruses have established genetic associations with the probability of developing a chronic infection, risk of disease progression, and likelihood of treatment response. We review genetic and genomic methods that have been used to study risk of HBV and HCV infection and patient outcomes. For example, genome-wide association studies have linked a region containing the interferon lambda genes to spontaneous and treatment induced clearance of HCV. We review the genetic variants associated with HCV and HBV infection, and how these variants affect specific expression or activities of their products. Further studies of these variants could provide insights into risk factors for and mechanisms of chronic infection and disease progression, as well as new strategies for treatment. PMID- 30287170 TI - Tropism for Spasmolytic Polypeptide-Expressing Metaplasia Allows Helicobacter pylori to Expand Its Intragastric Niche. AB - BACKGROUND & AIMS: In patients with chronic Helicobacter pylori infection, parietal and chief cell atrophy in the gastric corpus, a process known as spasmolytic polypeptide-expressing metaplasia (SPEM), increases the risk for progression to cancer. The relation between H pylori and these metaplastic changes is unclear. We investigated whether H pylori localizes to regions of SPEM. METHODS: We developed an in situ adherence assay in which we incubated H pylori with free-floating tissue sections from the gastric corpora of mice; we assessed H pylori distribution along the gastric unit by immunofluorescence. We analyzed the interactions of H pylori with tissue collected from mice with acute SPEM, induced by high-dose tamoxifen. We also evaluated how adhesin-deficient H pylori strains, chemical competition assays, and epithelial glycosylation affected H pylori adhesion to SPEM glands. We colonized mice with the mouse adapted PMSS1 strain and analyzed H pylori colonization in vivo during tamoxifen induced SPEM or after decrease of stomach acid with omeprazole. RESULTS: Compared with uninjured glands, H pylori penetrated deep within SPEM glands, in situ, through interaction of its adhesin, SabA, with sialyl-Lewis X, which expanded in SPEM. Helicobacter pylori markedly increased gastric corpus colonization when SPEM was induced, but this proximal spread reversed in mice allowed to recover from SPEM. Decreasing corpus acidity also promoted proximal spread. However, H pylori penetrated deep within corpus glands in vivo only when sialyl-Lewis X expanded during SPEM. CONCLUSIONS: Helicobacter pylori differentially binds SPEM glands in situ and in mice, in large part by interacting with sialyl-Lewis X. Our findings indicate that H pylori expands its niche into the gastric corpus by promoting and exploiting epithelial metaplastic changes that can lead to tumorigenesis. PMID- 30287171 TI - Targeted and Immune-based Therapies for Hepatocellular Carcinoma. AB - Treatment options for patients with hepatocellular carcinoma (HCC) are rapidly changing based on positive results from phase 3 trials of targeted and immune based therapies. More agents designed to target specific pathways and immune checkpoints are in clinical development. Some agents have already been shown to improve outcomes of patients with HCC, as first- and second-line therapies, and are either awaiting approval by the Food and Drug Administration or have been recently approved. We summarize the targeted and immune-based agents in trials of patients with advanced HCC and discuss the future of these strategies for liver cancer.

AB - RESEARCH QUESTION: Does salpingectomy for ectopic pregnancy affect the ovarian reserve measured by changes in pre- and post-operative levels of anti-Mullerian hormone (AMH)? DESIGN: This is a prospective observational multicentre study of 64 women treated with salpingectomy for an ectopic pregnancy. AMH was measured in serum samples collected at admission before salpingectomy and at follow-up (median time to follow-up [interquartile range] was 3 [3-4] months). Changes in serum AMH levels were investigated using Wilcoxon signed-rank test and the relationship between changes in AMH and age, time to follow-up, and pre-operative serum AMH level was investigated using linear regression analysis. The biological variation of AMH was also calculated. RESULTS: Serum AMH levels did not differ significantly before and after salpingectomy (median ?AMH [follow-up value minus admission value] 0.40 pmol/l, interquartile range -2.0 to 4.0 pmol/l). DeltaAMH was independent of age, time to follow-up and pre-operative serum AMH level. The intra-individual biological variation for AMH ranged from 12.1% to 26.3%, depending on time between the two samples. CONCLUSIONS: This is the first paired study to investigate serum AMH values before and after salpingectomy in an unselected population of women presenting with an ectopic pregnancy, including both patients who conceived naturally and following fertility treatment. It was found that salpingectomy for ectopic pregnancy had no short-term effect on serum AMH levels, and changes in AMH levels were independent of age, time to follow-up, and pre-operative serum AMH level. Furthermore, the study demonstrated a 6-month biological variation of AMH of less than 30%. PMID- 30287174 TI - Label-free detection of pepsinogen 1 and 2 by polyethylene coating Lamb microfluidic device. AB - Early screening of gastric cancer is a critical importance for the improvement of patients' survival rate. Here, a polyethylene coating Lamb (PE-Lamb) microfluidic device with immune layer for gastric cancer label-free detection was constructed. Two serum pepsinogen 1 (PG1) and pepsinogen 2 (PG2) biomarkers were applied to screen and predict the appearance of gastric cancer. Compared with enzyme-linked immunosorbent assay (ELISA), this method achieved a higher sensitivity and less time (40 min vs 120 min). The limit of detections (LOD) were reached 60 pg/mL for PG1 and 30 pg/mL for PG2, which have two orders of magnitude lower than traditional ELISA. The linearity coefficient indexes (R2) for PG1 and PG2 were 0.992 and 0.953 respectively, which is similar to that of ELISA. In addition, PG1 and PG2 mixed antigens sample with human serum was detected by PE-Lamb approach, and the frequency response showed high reproducibility and specificity. The results indicate that PE-lamb diagnostic technique is a novel and promising method for high-throughput screening and early diagnosis of gastric cancer. PMID- 30287175 TI - Development and application of a novel electrochemical immunosensor for tetracycline screening in honey using a fully integrated electrochemical Bio MEMS. AB - Tetracycline (TC) is a veterinary drug, wildly prescribed for prophylactic and therapeutic purposes. Consequently, its remaining residues in food products have to be regularized. We report in this paper about the development of a novel immunosensor based on an integrated bio micro-electromechanical system (Bio-MEMS) containing eight gold microelectrodes (uWEs), an integrated silver and platinum reference and counter electrodes, respectively. TC immobilization on the uWEs surface was conducted using three methods. The first through functionalization with 4-aminophenylacetic acid (CMA), the second by functionalization with CMA followed by preconcentration of a new structure of magnetic nanoparticles (MNPs) coated with poly (pyrrole-co-pyrrole-2-carboxylic acid) (Py/Py-COOH/MNPs) cross linked with Ab-TC, and the last one directly through the functionalization with Py/Py-COOH/MNPs. The analyte was quantified by competitive detection with TC immobilized on the uWEs surface toward specific polyclonal antibody (Ab-TC), using a mixture of a fixed concentration of Ab-TC and decreasing levels of TC one from 0.1 pg mL-1 to 1000 pg mL-1. Microcontact printing, followed by fluorescence microscopy characterization were performed during the functionalization of the immunosensor surface to certify that the corresponding immune detection process is taking place. This immunosensor was found to be highly sensitive with a limit of detection of 1.2 pg mL-1 and specific in the presence of interferents. The standard addition method was exploited to detect TC in honey samples. The present immunosensor platform is up-and-coming for TC detection which can dramatically decrease the time of analysis providing a new pathway for advanced immunoassays development in industrial food control.

AB - Aging is characterized by a morpho-functional adaptation, variably affecting major physiological systems, depending on a complex interaction between genetic, environmental and stochastic factors. This dynamic interaction drives an age related remodelling of a number of pathways/systems, providing the chance to reach the extreme limit of human life in healthy state which is reflected in the ever-increasing number of centenarians. This conceptualization implies that aging process per se and the development of the most common age-related diseases (ARD) are somewhat separate but must share somehow common set of basic biological mechanisms. One of the features that characterize both processes is the development and progression of an inflammatory state named inflammaging. Notably, inflammaging is characterized by a peculiar presentation, being a chronic, systemic, low grade and therefore for a long time subclinical, inflammatory process. For these reasons, even if the rate of progression of inflammaging is currently recognized as the main force driving aging and one of the main risk factors for clinical morbidity and mortality in the elderly, current knowledge on the causal agents are still incomplete and the "clinical evaluation" of inflammaging has not yet been standardized. Even if a number of biomarkers of inflammaging have been identified, their analysis is not recommended as part of the routine evaluation of elderly patients. This review will aim to describe the concept of inflammaging within several other concepts such as the definition of aging per se and how we integrate it in the context of ARD. PMID- 30287178 TI - The Impact of Breast Density Reporting Laws on Women's Awareness of Density Associated Risks and Conversations Regarding Supplemental Screening With Providers. AB - OBJECTIVE: We conducted a national survey to understand the impact of state-level density reporting laws on women's level of density risk awareness and their engagement in conversations with providers regarding supplemental screening. METHODS: In all, 1,500 US women aged 40 to 74 years who obtained a mammogram within 2 years were surveyed in February 2018. The sampling design yielded 300 respondents in each of five groups categorized based on density reporting law features. Women were asked about their breast density-related knowledge, importance of being notified, and sources of information and if conversations with providers regarding density and supplemental screening occurred. Survey results were compared across groups and between women residing in states with versus without density laws. RESULTS: The majority of respondents in all groups felt that it is important for women to know their breast density type (range, 85% 90%). Women were most likely informed of breast density type by a health care provider (range, 68%-72%), followed by the mammography result letter (range, 48% 68%), and then a radiologist (range, 46%-61%). Women from states with a density law were significantly more likely to have learned of their breast tissue type from a mammogram results letter (60% versus 48%, P = .011) and discuss supplemental screening (67% versus 53%, respectively; P = .008) than women from states without a law. CONCLUSION: State-level density reporting laws are associated with increased breast density awareness and increased likelihood of conversations between women and their providers regarding supplemental screening. PMID- 30287179 TI - Ultrasound-assisted oil-in-water nanoemulsion produced from Pereskia aculeata Miller mucilage. AB - For the preparation of nanoemulsions, the correct choice of emulsifiers, together with the emulsification methods, directly influences the final product quality. The present study reports the ultrasound-assisted preparation of oil-in-water nanoemulsions produced with mucilage extracted from leaves of Pereskia aculeata Miller (ora-pro-nobis; OPN). The OPN mucilage (%) and soybean oil (%) concentration range, and the process operating parameters, ultrasonic power amplitude (%) and sonication time (min), were optimized based on the mean droplet diameter (d32). The effect of the mucilage and oil concentrations was also investigated by the response variables such as polydispersity, density, turbidity, viscosity, zeta-potential, and interfacial tension. The higher OPN mucilage concentrations (%) with lower amounts of soybean oil (%) favored nanoemulsion formations (116 <= d32 <= 171 nm) and increased polydispersity, density, and zeta-potential. On increasing OPN mucilage and soybean oil the turbidity of the dispersions increased. All colloidal systems showed Newtonian behavior, and the viscosity in the systems increased due to the greater OPN mucilage concentration in the aqueous phase at a certain oil concentration. In addition, lower values of equilibrium interfacial tension were found with increasing OPN mucilage concentrations. Finally, from the stability test, it can be pointed out that the OPN mucilage concentration should be between 1.0 and 1.5% and the oil concentration should be less than 5%, so that lower d32 values are maintained over time. Therefore, mucilage extracted from OPN and the ultrasound technique can be used in the preparation of nanoemulsions. PMID- 30287180 TI - Ultrasound-assisted synthesis of two-dimensional layered ytterbium substituted molybdenum diselenide nanosheets with excellent electrocatalytic activity for the electrochemical detection of diphenylamine anti-scald agent in fruit extract. AB - Metal chalcogenides with large active sites have been received great attention as an excellent catalyst due to their hierarchical structural properties. Here, we have demonstrated the synthesis of ytterbium-doped molybdenum selenide (YbMoSe2) in the form of two-dimensional nanosheets by using a simple ultrasonic method. The formation of the crystal phase of prepared YbMoSe2 nanosheets was studied by using the selective characterization techniques. The reported HRTEM confirmed that the introduction of heterogeneous spin of Yb with MoSe2 creates the lattice distortion. Thus, the active sites can be increased by creating the lattice distortion on the basal plane of the metal chalcogenides nanosheets. The band gap study was carried out by using UV-visible spectrometer and demonstrated the decreasing band gap of MoSe2 from 1.30 eV to 1.15 eV due to the Yb substitution/doping. The increasing active sites with decreasing band gap facilitate an excellent electronic conductivity and electrochemical activity. Furthermore, the electrocatalytic activity of YbMoSe2 modified glassy carbon electrode (YbMoSe2/GCE) toward the sensing of diphenylamine (DPA) anti-scald agent. As expected, YbMoSe2/GCE showed a high level of electrochemical activity with a low limit of detection (0.004 uM) and excellent sensitivity (11.4 uA uM-1 cm-2) towards the detection of DPA. In addition, the superior selectivity, stability, and reproducibility of YbMoSe2/GCE also were recorded. The beneficial electrochemical activity of YbMoSe2/GCE offered the more advantages to detection of DPA in the food sample also. PMID- 30287181 TI - Ultrasonically formation of supramolecular based ultrasound energy assisted solidification of floating organic drop microextraction for preconcentration of methadone in human plasma and saliva samples prior to gas chromatography-mass spectrometry. AB - In this work, an ultrasonic-assisted supramolecular based on solidification of floating organic drop microextraction (UA-SM-SFO-ME) was developed as a green method for preconcentration of methadone prior to gas chromatography-mass spectrometry (GC-MS). The supramolecular solvent aggregates containing reverse micelles of 1-dodecanol in tetrahydrofuran (THF) were formed by ultrasonication that subsequently dispersed in the sample solution. Ultrasonic waves caused the fast formation of supramolecular solvent aggregates. In this work, ultrasonication was used in two phases: First phase, the formation of reverse micelles and the second phase, the dispersion of supramolecular solvent in the sample solution. Actually, ultrasonication was basic of this presented work. In order to provide the highest extraction efficiency, the influence of various parameters on the method performance (supramolecular solvent type and volume, disperser solvent condition, pH, extraction time and salt concentration) was investigated. Based on the obtained optimum conditions, the limits of detection (LODs) and the limits of quantitation (LOQs) were obtained 0.5-1.2 ug L-1 and 1.2 2.5 ug L-1 with preconcentration factors in the range of 182-191, in water and biological samples, respectively. Subsequently, the method was assessed for preconcentration of the methadone in human plasma and saliva samples. PMID- 30287182 TI - Factors associated with bariatric surgery utilization among eligible candidates: who drops out? AB - BACKGROUND: Bariatric surgery is underutilized. OBJECTIVES: To identify factors associated with eligible patient dropout from bariatric surgery. SETTING: University hospital, United States. METHODS: Eligible candidates were identified after a multidisciplinary review committee (MRC) of all patients (n = 484) who attended a bariatric surgery informational session (BIS) at a single-center academic institution in 2015. We compared patients who underwent surgery within 2 years of BIS with those who did not (i.e., dropped out) by evaluating patient, insurance, and program-specific variables. Univariate analyses and multivariable regressions were performed to identify factors associated with patient dropout among eligible candidates. RESULTS: We identified 307 (63%) patients who underwent MRC. Thirty-three (11%) patients were deemed poor candidates and surgery was not recommended. Among eligible candidates, 82 (30%) dropped out from the program. Factors independently associated with eligible patient dropout included coronary artery disease (odds ratio [OR] .13 [.02-.66]; P = .014), hypertension (OR .46 [.24-.87]; P = .017), time from BIS to MRC (OR .99 [.99 .99]; P = .002), 3 months of medically supervised weight loss documentation (OR .09 [.02-.51]; P = .007), endocrinology clearance (OR .26 [.09-.76]; P = .014), hematology clearance (OR .37 [.14-.95]; P = .039), urine drug screen testing (OR .31 [.13-.72]; P = .006), additional psychological evaluation (OR .43 [.20-.93]; P = .031), and required extra sessions with the dietician (OR .39 [.17-.92]; P = .032). Thirty-three (6.8%) patients underwent surgery at another institution, and 42% of these patients lived more than 50 miles from attended BIS site. CONCLUSIONS: Twenty-seven percent of patients did not undergo bariatric surgery at their initial site of evaluation despite being considered eligible candidates after MRC. Dropout was independently associated with patient, insurance, and program-specific variables that may represent barriers to care amenable to improvement. PMID- 30287183 TI - Intravenous and Inhaled Milrinone in Adult Cardiac Surgery Patients: A Pairwise and Network Meta-Analysis. AB - OBJECTIVE: To summarize the evidence on the hemodynamic, echocardiographic, and clinical effects of inhaled and intravenous milrinone (iMil and IvMil) in adult cardiac surgery patients. DESIGN: Systematic review, pairwise and network meta analysis. SETTING: Multi-institutional. PARTICIPANTS: Adult cardiac surgery patients. INTERVENTIONS: Comparison between iMil and IvMil versus other agents or placebo. MEASUREMENTS AND MAIN RESULTS: The primary endpoints were mean pulmonary artery pressure (MPAP) and peripheral vascular resistance (PVR). Secondary endpoints included the following: (1) mean arterial pressure, heart rate, and cardiac index (CI); (2) echocardiographic data; and (3) clinical outcomes. Random model, leave-one-out-analysis, and meta-regression were used. Thirty studies (6 iMil and 24 IvMil) were included for a total of 1,438 patients (194 iMil and 521 IvMil). IvMil was associated with a lower MPAP, lower PVR, and higher CI compared to placebo (standardized mean difference [SMD] = -0.22 [95% CI = -0.48 to 0.05], SMD = -0.49 [95% CI = -0.71 to -0.27], and SMD = 0.94 [95% CI = 0.51 to 1.37]). No difference in any outcome was found between iMil and placebo. At network meta analysis, significantly lower PVR and shorter hospital length of stay were found for IvMil compared to iMil (SMD = -0.82 [95% CI = -1.53 to -0.10] and SMD = -0.50 [95% CI = -0.95 to -0.05], respectively). CONCLUSION: These results support the clinical use of IvMil in cardiac surgery patients. No evidence at present supports the adoption of iMil. PMID- 30287184 TI - Increased age and proton pump inhibitors are associated with severe Clostridium difficile infections in children. AB - BACKGROUND: Clostridium difficile infection (CDI) is increasing in children. We aimed to compare the clinical characteristics between CDI and colonization and to identify the risk factors for severe diseases of CDI in children. METHOD: We retrospectively reviewed 124 children (1-18 years old) from 2011 to 2018. CDI was defined as diarrhea (>=3 loose stool in the past 24 h) with confirmed toxigenic strain. Colonization was defined as presence of C. difficile without clinical symptoms. Severe diseases included ileus, acute kidney injury, gastrointestinal bleeding or mortality. Patients younger than 1 year old and coinfections with other enteric pathogens were excluded. RESULTS: Among 124 patients with C. difficile identified, 49 of them fulfilled CDI definition and 75 had C. difficile colonization. Children with CDI were more likely to present with watery (74% vs. 1%, p < 0.01) and mucoid stool (25% vs. 7%, p < 0.01) and occult blood in stool (67% vs. 33%, p < 0.01) than children with colonization. In CDI cases, elevated age-adjusted creatinine (18% vs. 0%, p = 0.03) and hyponatremia (134 mEq/L vs. 137 mEq/L, p = 0.04) were found. Also, they had more complicated diseases (27% vs. 0%, p < 0.01). On multivariate analysis, age older than 4 years (adjusted odds ratio: 5.83; 95% confidence interval: 1.05-32.27) and proton pump inhibitor use (PPI) (adjusted odds ratio: 7.25; 95% confidence interval: 1.07-49.07) were the independent factors for severe diseases. CONCLUSIONS: Watery diarrhea, mucoid stool and occult blood in stool could differentiate CDI from colonization. Patients with increased age and previous PPI use were the independent risk factors for severe diseases in children.

AB - Severe combined immunodeficiency disease (SCID) mice with human lepidic adenocarcinoma were established by the intrabronchial implantation of fresh surgically resected specimens. Human pulmonary adenocarcinoma tissue from 16 different cases was transplanted into SCID mice, and SCID mouse tumors were established from four of these cases (25%). Among the four tumors, the tumor cells of two SCID mice showed replacement lepidic growth of mouse alveolar structures accompanied by multiple intrapulmonary lesions. Human lung carcinoma cell lines showing lepidic growth are rare and the xenograft models using the SCID mouse model developed in the current study will be useful for analyzing the growth and/or progression patterns and clinical behavior of lepidic adenocarcinoma, the major histological subtype of human carcinoma of the lung. PMID- 30287186 TI - Antimicrobial activity of solithromycin and levofloxacin against a murine pneumonia mixed-infection model caused by Streptococcus pneumoniae and anaerobic bacteria. AB - INTRODUCTION: Solithromycin is a novel fluoroketolide developed to treat pneumonia. But, few studies evaluating its antimicrobial activity against S. pneumoniae in a mixed-infection model with anaerobes are available, while community-acquired pneumonia can involve mixed-infection of Streptococcus pneumoniae and anaerobic bacteria. This study evaluated the antimicrobial activity of solithromycin against macrolide-resistant S. pneumoniae and anaerobic bacteria with a murine pneumonia mixed-infection model. MATERIAL AND METHODS: We evaluated antimicrobial activity of solithromycin (10 and 20 mg/kg) and levofloxacin (126 mg/kg) against S. pneumoniae with a three-point mutation in penicillin-binding protein and an ermB gene, and Parvimonas micra. Antimicrobial efficacy was calculated for each isolate as the change in bacterial count (Deltalog10 CFU/mL) obtained in the treated mice after 24 h compared with the count in the starting control animals. RESULTS: The solithromycin and levofloxacin minimum inhibitory concentrations (MICs) for S. pneumoniae were 0.03 and 0.5 MUg/mL, respectively. The solithromycin and levofloxacin MICs for P. micra were 0.015 and 0.12 MUg/mL, respectively. In a mixed-infection model, solithromycin showed significantly higher antimicrobial activity against S. pneumoniae than levofloxacin (solithromycin 20 mg/kg; -2.87 +/- 1.33 log10 CFU/mL vs. levofloxacin; -1.35 +/- 0.37 log10 CFU/mL, p = 0.0397). Similarly, solithromycin showed significantly higher antimicrobial activity against P. micra than levofloxacin (solithromycin 20 mg/kg; -2.78 +/- 0.98 log10 CFU/mL vs. levofloxacin; -1.57 +/- 0.47 log10 CFU/mL, p = 0.0400). DISCUSSION: Solithromycin showed higher antimicrobial activities against macrolide-resistant S. pneumoniae and P. micra than levofloxacin, even though they were coexisted in murine lung tissue. Our results suggest that solithromycin could be effective for pneumonia patients due to S. pneumoniae to reduce bacterial density in lung tissue. PMID- 30287187 TI - The involvement of estrogen receptors alpha and beta in the in vitro effects of 17beta-estradiol on secretory profile of peritoneal macrophages from naturally menopausal female and middle-aged male rats. AB - The systemic and extra- gonadal levels of 17beta-estradiol (E2) change during aging, and affect the expression of estrogen receptors (ERs) in the immune cells of both females and males. The age-related cessation of ovarian function in females, as well as the tissue-specific expression of enzyme aromatase (estrogen synthase which significantly rises with the advancing age) in both males and females, both determine the concentration of E2 to which immune cells may be exposed. The present study was set up to investigate the direct influence of E2 in vitro on the secretory profile of peritoneal macrophages from young and naturally menopausal female rats, and from young and middle-aged male rats. The involvement of receptor(s) responsible for mediating the effects of E2 in vitro was examined by use of antagonists specific for ERalpha or ERbeta. Whereas in macrophages from young female rats E2 treatment diminished interleukin (IL)-1beta secretion, it increased it in young males, and the middle-aged females. The in vitro E2 treatment increased tumor necrosis factor (TNF)-alpha release by macrophages from young rats of both sexes, while it increased macrophage IL-6 release independently of both sex and age. At the same time, E2 decreased hydrogen peroxide (H2O2) production in macrophages from females, and increased it in male rats of both ages, whereas it diminished nitric oxide (NO) release in all experimental groups. Inspite of the sex- and age-specific effects of E2 on macrophage urea release, E2 did not affect the NO/urea ratio in macrophages from female rats, and diminished it in macrophages from both young and middle-aged male rats. Independently of the sex and age, E2 stimulated the release of inflammatory cytokines predominantly via macrophage ERalpha, and inhibited the IL 1beta release in young females via ERbeta. In contrast, E2 increased macrophage H2O2 and urea production by activating ERbeta, but diminished their release via ERalpha. Our study may contribute to better understanding of the complex role(s) that E2 may play in innate immunity during aging, and that are dependent of sex.

PMID- 30287189 TI - Enhanced antimicrobial, antioxidant, in vivo antitumor and in vitro anticancer effects against breast cancer cell line by green synthesized un-doped SnO2 and Co doped SnO2 nanoparticles from Clerodendrum inerme. AB - A novel approach was employed for the synthesis of un-doped tinoxide and Cobalt doped tinoxide (Co-doped SnO2) nanoparticles (NAPs) by using aqueous extract of Clerodendrum inerme with the help of eco-friendly superficial solution combustion method. Synthesized NAPs were characterized by different spectroscopic techniques and results from XRD, TEM, SEM, EDX and UV-Vis examines confirmed the successful synthesis, crystalline nature and spherical structure of un-doped SnO2 and Co doped SnO2 NAPs with the average grain size of 30 and 40 nm; and band gap energy of 3.68 and 2.76 eV respectively. Antimicrobial propensity of the synthesized NAPs was determined by agar well assay, SEM, TEM and confocal laser scanning microscopic analysis against various bacterial and fungal strains. Synthesized Co doped SnO2 NAPs were unveiled the extraordinary antibacterial and antifungal activities against E. coli, B. subtilis, A. niger, A. flavus, and C. albicans with the zone of inhibitions of 30 +/- 0.08 mm and 26 +/- 0.06 mm, 17 +/- 0.04 mm, 23 +/- 0.08 mm and 26 +/- 0.06 respectively which were also evidenced from SEM, TEM and confocal laser scanning microscopy. In addition, green synthesized Co-doped SnO2 NAPs were demonstrated the substantial antioxidant activity by scavenging DPPH, significant in vitro anticancer and in vivo antitumor activity on breast carcinoma cells (MCF-7) and Ehrlich ascites tumor cell lines respectively than standard. The hemolytic activity disclosed low cytotoxicity of fabricated NAPs (0.89 +/- 0.05%) at 5 mg/mL, which was indicated their biocompatibility potential. Hence, the multi-purpose properties of synthesized NAPs presented in the current study can be further deliberated for pharmaceutical and nanomedicine applications. PMID- 30287190 TI - Cortisol responses of goldfish (Carassius auratus) to air exposure, chasing, and increased water temperature. AB - Fish can respond to stimuli from the internal or external environment with activation of the hypothalamo-pituitary-interrenal (HPI) axis and the secretion of cortisol. Stimuli that activate the HPI axis of fish include short term air exposure and increases in water temperature. The present study was conducted to determine how quickly cortisol concentrations increase in goldfish subjected to an increase in water temperature, and to compare the response to an increase in water temperature with responses to other stimuli. Plasma cortisol concentrations varied widely between individual goldfish, with concentrations ranging from 9.1 to 516.0 ng/mL in goldfish on the day of arrival from the supplier. Mean cortisol concentrations in undisturbed goldfish were low (4.5 +/- 1.0 ng/mL). Mean cortisol concentrations in fish exposed to air for 3 min and in fish that experienced chasing for 10 min were markedly elevated 15 min after the beginning of the stimuli (132.6 +/- 31.0 and 121.1 +/- 23.9 ng/mL respectively). Mean cortisol concentrations in fish that experienced an increase in water temperature rose to 22.2 +/- 7.6 ng/mL after 15 min, declined to <10 ng/mL at 30 and 60 min then increased and were elevated (79.0 +/- 10.8 ng/mL) at 240 min. Cortisol measurements can be used to indicate the responsiveness of fish to changes in water temperature and goldfish will be a convenient study species for the development of studies of plasticity in responses of fish to increases in water temperature that are happening due to climate change. PMID- 30287191 TI - The use of hair cortisol for the assessment of stress in animals. AB - The hair cortisol concentration (HCC) is assumed to be a retrospective marker of integrated cortisol secretion and stress over longer periods of time. Its quantification is increasingly used in psychoneuroendocrinological studies in humans, but also in animal stress and welfare research. The measurement of HCCs for the assessment of stress offers many considerable benefits for use in domesticated and wild animals, especially due to the easy and minimally invasive sampling procedure and the representation of longer time periods in one sample. This review aims to outline the different fields of application and to assess the applicability and validity of HCC as an indicator for chronic stress or long-term activity of the hypothalamic-pituitary-adrenal axis in wild and domesticated animals. Specific hair characteristics are presented and the advantages and limitations of using HCC are discussed. An overview of findings on the impact of stress- and health-related factors on HCCs and of diverse influencing factors causing variation in hair cortisol levels in different species is given. Recommendations for the use of hair cortisol analysis are proposed and potential fields of future research are pointed out. The studies indicate an effect of age and pregnancy on HCCs, and cortisol incorporation into hair was also found to depend on hair colour, body region, sex and season of year, but these results are less consistent. Furthermore, the results in animals show that a wide array of stressors and pathological conditions alters the cortisol concentrations in hair and that HCC thereby provides a reliable and valid reflection of long-term cortisol secretion in many species. However, more research is necessary to investigate the underlying mechanisms of cortisol incorporation into the hair and to explore the hair growth characteristics in the species of interest. To overcome confounding influences, the use of standardized sampling protocols is strongly advised. PMID- 30287192 TI - The utility of motor unit number index: A systematic review. AB - The need for a valid biomarker for assessing disease progression and for use in clinical trials on amyotrophic lateral sclerosis (ALS) has stimulated the study of methods that could measure the number of motor units. Motor unit number index (MUNIX) is a newly developed neurophysiological technique that was demonstrated to have a good correlation with the number of motor units in a given muscle, even though it does not necessarily accurately express the actual number of viable motor neurons. Several studies demonstrated the technique is reproducible and capable of following motor neuron loss in patients with ALS and peripheral polyneuropathies. The main goal of this review was to conduct an extensive review of the literature using MUNIX. We conducted a systematic search in English medical literature published in two databases (PubMed and SCOPUS). In this review, we aimed to answer the following queries: Comparison of MUNIX with other MUNE techniques; the reproducibility of MUNIX; the utility of MUNIX in ALS and preclinical muscles, peripheral neuropathies, and other neurological disorders. PMID- 30287193 TI - Vagus nerve stimulation promotes generalization of conditioned fear extinction and reduces anxiety in rats. AB - BACKGROUND: Exposure-based therapies are used to treat a variety of trauma- and anxiety-related disorders by generating successful extinction following cue exposure during treatment. The development of adjuvant strategies that accelerate extinction learning, improve tolerability, and increase efficiency of treatment could increase the efficacy of exposure-based therapies. Vagus nerve stimulation (VNS) paired with exposure can enhance fear extinction, in rat models of psychiatric disorders, and chronic administration of VNS reduces anxiety in rats and humans. OBJECTIVE: We tested whether VNS, like other cognitive enhancers, could produce generalization of extinction for stimuli that are not presented during the extinction sessions, but are associated with the fear event. METHODS: Male Sprague Dawley rats underwent auditory fear conditioning with two easily discriminable auditory stimuli. Following fear conditioning, extinction training consisted of exposure to only one of the conditioned sounds. Half of the rats received VNS and half received sham stimulation during with sound presentations. VNS effects on anxiety were examined in a separate study where VNS was administered prior to testing on the elevated plus maze. RESULTS: Sham stimulated rats given 20 presentations of a conditioned stimulus (CS) during the extinction session showed performance that was matched to VNS-treated rats given only 4 presentations of the CS. Despite comparable levels of freezing to the presented CS, only the VNS-treated rats showed a significant decrease in freezing to the CS that was not presented. VNS-induced generalization of extinction was observed only when the two sounds were paired with footshock within the same fear conditioning session; VNS did not promote generalization of extinction when the two sounds were conditioned on different days or in different contexts. On the anxiety test, VNS administration significantly increased time spent in the open arms of the elevated plus maze. CONCLUSION: These results provide evidence that VNS can promote generalization of extinction to other stimuli associated with a specific fear experience. Furthermore, non-contingent VNS appears to reduce anxiety. The ability to generalize extinction and reduce anxiety makes VNS a potential candidate for use as an adjunctive strategy to improve the efficacy and tolerability of exposure-based therapies. PMID- 30287194 TI - The flavonoid acetylpectolinarin counteracts the effects of low ethanol on spontaneous network activity in hippocampal cultures. AB - ETHNOPHARMACOLOGICAL RELEVANCE: A major concern in modern society involves the lasting detrimental behavioral effects of exposure to alcoholic beverages. Consequently, hundreds of folk remedies for hangover have been suggested, most of them without a scientific basis, for lack of proper test systems. Over centuries, yellow toadflax (Linaria vulgaris Mill., Lv) tincture has been used in Russian traditional medicine to treat the spectrum of hangover symptoms such as vertigo, headache, drunken behaviors, and as a sedative. MATERIALS AND METHODS: Here we use in-vitro cultured hippocampal neurons to examine the effect of the Lv extract as well as the flavonoid acetylpectolinarin (ACP) exclusively found in Lv extract, on spontaneous network activity of the cultured neurons exposed to low, physiological concentrations of ethanol. RESULTS: As in previous studies, low (0.25-0.5%) ethanol causes an increase in network activity, which was converted to suppression, with high concentrations of ethanol. Lv extract and ACP, at low concentrations, had no appreciable effect on spontaneous activity, but they blocked the facilitating action of low ethanol. This action of ACP was also seen when the culture was exposed to 1-EBIO, a SK potassium channel opener, and was blocked by apamin, an SK channel antagonist. In contrast, ACP or Lv extracts did not reverse the suppressive effects of higher ethanol. CONCLUSIONS: Our results suggest that ACP acts by interacting with the SK channel, to block the facilitatory effect of low concentration of ethanol, on network activity in hippocampal cultures. PMID- 30287195 TI - Rosmarinus officinalis essential oil: A review of its phytochemistry, anti inflammatory activity, and mechanisms of action involved. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Plant species Rosmarinus officinalis L. (Lamiaceae; Synonyms: Salvia rosmarinus Schleid. and Rosmarinus angustifolius Mill.) is a herb widely used worldwide. In local and traditional medicine, its used for inflammation-related diseases. Currently, studies report anti inflammatory activity in its essential oil (EORO). However, to better understand EORO's anti-inflammatory activity its necessary to understand its phytochemistry and the signaling pathways affected by it. Hence, this review aimed to describe EORO phytochemical profile, ethnopharmacological uses, some biological activities of EORO will be described but emphasizing its anti-inflammatory potential and possible mechanisms of action involved. MATERIALS AND METHODS: The research was performed using the databases Medline, Embase, BVS Regional Portal, Science Direct, CAPES Journals, and Scopus; using the keywords "Rosmarinus officinalis", "anti-inflammatory" and "essential oil". Additional information was gathered from related textbooks, reviews, and documents. RESULTS AND DISCUSSION: Until now about 150 chemical compounds were identified in EORO samples, more frequently reported molecules were 1,8-cineole, alpha-pinene, and camphor. Studies suggest that the anti-inflammatory activity of EORO occur mainly through inhibition of NF kappaB transcription and suppression of arachidonic acid cascade. Its antioxidant activity also aids by preventing injury caused by the reactive species of inflammation; its smooth muscle relaxant activity contributes to ameliorating airway inflammatory diseases. Lastly, toxicity assessments indicate low toxicity to EORO. CONCLUSIONS: Current evidence indicates anti-inflammatory activity in EORO, supporting its ethnopharmacological uses in inflammatory-related diseases, and potential future applications. However, although considerable acute inflammatory models were tested, more chronic inflammatory models are needed; clinical studies are still absent, this may be due to the high doses needed for essential oils to exert pharmacological effects, but recent studies show this issue can be bypassed using the oil formulated as nanoemulsions to improve its bioavailability. PMID- 30287196 TI - Cytotoxicity of Luffa cylindrica (L.) M.Roem. extract against circulating cancer stem cells in hepatocellular carcinoma. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Luffa cylindrica (L.) M.Roem. has been recognized as traditional medicine for the treatment of various diseases like inflammatory diseases, diarrhea and viral infections. The usual parts used include fruit, seeds and leaves. AIM OF THE STUDY: To evaluate the anticancer activity of the hot water extract of the whole plant of Luffa cylindrica using circulating tumor cells and cancer stem cells isolated from the peripheral blood of hepatocellular carcinoma patients in vitro. MATERIALS AND METHODS: Seventy five adult patients who reported as stage II and III Hepatocellular carcinoma were selected. Blood samples were withdrawn and the circulating tumor cells were isolated from the whole blood. Tumor cells and cancer stem cells were detected and isolated by flow cytometric techniques. The isolated cell types were cultured and propagated in the tissue culture facility, the extract was tested on the isolated cells. RESULTS: Luffa cylindrica hot water extract has shown cytotoxic activity against circulating tumor cells of hepatocellular carcinoma especially the cells sub population CD133+/CD44+ with little effect among CD133+/CD44- sub-population. CONCLUSION: Hot water extract of Luffa cylindrica whole plant could decrease the ratio of cancer stem cells in blood of HCC patients and may be used to minimize recurrence and metastasis in hepatocellular carcinoma patients. PMID- 30287197 TI - Are polyphenol antioxidants at the root of medicinal plant anti-cancer success? AB - ETHNOPHARMACOLOGICAL RELEVANCE: Given the severe side effects associated with most of the conventional cancer medications, as well as the expanding body of evidence indicating secondary toxicity of these drugs, individuals with cancer are increasingly turning to natural alternatives. Similarly, the pharmaceutical industry is in search of natural products to treat cancer. An understanding of the specific active components in plant products with which anti-cancer efficacy is achieved is required for this research to move forward. AIM OF THE STUDY: To integrate data from cancer-relatestudies on plant-derived products or extracts, to elucidate whether these products may have similar active ingredients and/or mechanisms of action, that can explain their efficacy. This review also includes a discussion of the methodological complexities and important considerations involved in accurate isolation and characterisation of active substances from plant material. CONCLUSIONS: From the literature reviewed, most plant products with consistently reported anti-cancer efficacy contains high levels of polyphenols or other potent antioxidants and their mechanisms of action correlate to that reported for isolated antioxidants in the context of cancer. This suggests that natural products may indeed become the panacea against this chronic disease - either as therapeutic medicine strategy or to serve as templates for the design of novel synthetic drugs. The recommendation is made that antioxidant activity of plant actives and especially polyphenols, should be the focus of anti cancer drug discovery initiatives. Lastly, researchers are advised to exploit current techniques of chemical compound characterisation when investigating polyphenol-rich plants to enable the easy consolidation of research findings from different laboratories. PMID- 30287198 TI - A Systematic Review of Training in Symptom Management in Palliative Care Within Postgraduate Medical Curriculums. AB - CONTEXT: Symptom management is a priority area within palliative care core competencies for generalist providers. Although several educational initiatives exist, a comprehensive evidence synthesis on the effectiveness of symptom management training on trainees' learning and patient-reported outcomes is lacking. OBJECTIVES: The objective of this study was to determine the effectiveness of training in symptom management in palliative care providers in nonpalliative specialties. METHODS: This is a systematic review following Best Evidence Medical Education methods from searches of MEDLINE, EMBASE, ERIC, CINAHL, PsycINFO, Cochrane database of systematic, Clinical Trials.gov, and ISRCTN databases to September 2017. Prospective controlled studies testing the impact of symptom management educational interventions on physicians in training in nonpalliative specialties were included. Data were summarized narratively, grouped by curriculum description, and effectiveness on trainees' learning or patient-reported outcomes. RESULTS: Of 5062 records identified, six studies met the inclusion criteria: two randomized controlled trials and four quasi experimental. Pain management and use of opioids and their side effects were most frequently covered. Clinical decision support tools, Web-based teaching, palliative care rotation, and mixed educational methods were used. Most studies used self-reported, original, or modified evaluation instruments, although psychometric properties were seldom reported. Despite methodological considerations, all educational methods improved trainees' learning outcomes. However, the effects on trainees' behavior and patient-related outcomes were not evaluated. CONCLUSION: Current educational training programs in symptom management appear to improve trainees' comfort, preparedness, and knowledge in assessing and managing patients' symptoms at the end of life. More rigorous research to evaluate the impact of this training on residents and organizational performance is now required. PMID- 30287199 TI - Society of Hematologic Oncology State of the Art Update and Next Questions: Multiple Myeloma. AB - During the past decade, the survival outcomes of patients with multiple myeloma (MM) have dramatically improved, not only owing to the advent of a number of novel therapies, but also to the deepening insight regarding how to best use these options. Triplet-based induction regimens can yield overall response rates of <= 100%. In the relapsed and refractory setting, we have a multitude of doublet and triplet options available with high and durable response rates. The addition of monoclonal antibodies has provided a new class of agents to augment our standard approach with novel therapies. Minimal residual disease status testing has worked its way into the lexicon of the myeloma-treating physician and provides both prognostic and potentially therapeutic insight into management. Despite the influx of novel therapies, high-dose melphalan with autologous stem cell rescue remains a vital tenet of induction therapy for our younger and more fit patients. The current generation of clinical trials using immunologic approaches such as bifunctional antibodies and chimeric antigen receptor T cells is extremely promising and will likely become the future standard of care. Although the disease remains, on the whole, incurable, we now possess therapeutic modalities that can provide deep and durable remissions and, potentially, cure for some. PMID- 30287200 TI - Role of Proteasome Inhibitors in Relapsed and/or Refractory Multiple Myeloma. AB - Proteasome inhibition is an established treatment strategy for patients with multiple myeloma as proteasome inhibitors (PIs) selectively target and disrupt the protein metabolism of aberrant plasma cells. Since the introduction of the first-in-class PIs bortezomib, the therapeutic landscape for multiple myeloma has shifted with the development of next-generation PIs (carfilzomib and ixazomib) and new classes of agents. Treatment with modern combination therapies has been shown to result in deep responses and improved outcomes, and these potent regimens are increasingly used as frontline therapy. As patients continue to live longer with modern frontline therapy, there will be an increased need for effective regimens after initial treatment failure. Several recent studies have shown that treatment with combination therapy incorporating PIs induces deep and durable responses in patients with relapsed and/or refractory multiple myeloma. In this review, we review pivotal data and discuss the role of PIs-based doublet and triplet regimens for the management of relapsed/refractory multiple myeloma in the era of modern combination therapy.

AB - OBJECTIVE: The aim of this study was to evaluate the efficacy of platelet-rich fibrin (PRF) in the healing of impacted mandibular third molar (M3) extraction sockets. STUDY DESIGN: This study included 30 patients with bilaterally symmetric impacted M3 (N = 60) requiring transalveolar extraction. All patients were assigned numbers randomly; left-sided M3 patients with odd numbers and right sided patients with even numbers were categorized into group A (test group), and the other side of the mouth was classified as "group B" (control group). Group A M3 extraction sockets received PRF, whereas group B sockets were closed without PRF. Patients were evaluated for pain and swelling on postoperative days 1, 3, 7, and 14. Bone healing was compared on postoperative weeks 8 and 16. Analysis of variance (ANOVA) and Tukey's multiple comparison tests were applied for statistical analysis. RESULTS: A total of 30 patients, ages 18 to 40years, participated in this study. The overall postoperative pain score (visual analogue scale [VAS]) and facial swelling percentages were lower for group A compared with group B (P < .05). Early bone healing was also evident on postoperative radiographs obtained at weeks 8 and 16 in group A (P < .001). CONCLUSIONS: The use of autologous PRF aids in earlier and better wound healing in a controlled manner. PMID- 30287203 TI - Early detection of cherubism with eventual bilateral progression: a literature review and case report. AB - Cherubism is a rare familial disease of childhood that commonly affects the bilateral mandible and maxilla and typically resolves in adulthood. It has been shown to have a male predilection and has been mapped to the SH3 BP2 gene. Only 2 cases of unilateral cherubism have been documented in the literature; in the first case, the contralateral side was eventually affected. Although rare, unilateral cherubism presents a diagnostic dilemma. This case report describes a unique presentation of unilateral cherubism that progressed to affect the contralateral side and describes some of the considerations in the diagnosis and treatment of unilateral benign giant cell lesions of the jaws. PMID- 30287204 TI - Analytical polyphosphate extraction from Saccharomyces cerevisiae. AB - In Saccharomyces cerevisiae, inorganic polyphosphate is analyzed by polyphosphate extraction and subsequent quantification. Recently, we developed a method for polyphosphate quantification, and length determination of short chain polyphosphate. However, the lack of a simple, optimized and validated method for analytical polyphosphate extraction has both hindered the advance in this research field, and prevented comparability of results between laboratories. Hence, the goal of this study was to develop an analytical method for polyphosphate extraction from S. cerevisiae. Several literature methods were compared with special attention to omission of polyphosphate precipitation steps, because these work neither at low polyphosphate concentrations nor quantitatively. The best literature protocol, which takes 5.5 h and requires five reaction tubes per sample, was optimized here in regards to the amount of extracted polyphosphate and simplification of the work flow. The final protocol extracts 40 % more polyphosphate than the best literature method, takes only 30 min, requires just one reaction tube per sample, and is, therefore, proposed as the new gold standard for analytical polyphosphate extraction from S. cerevisiae. In combination with our recently published polyphosphate quantification method, total polyphosphate in S. cerevisiae can now be analyzed within 2 h. PMID- 30287205 TI - A bare covered stent.

AB - OBJECTIVE/BACKGROUND: The aim was to evaluate the quality of current venous leg ulcer (VLU) clinical practice guidelines (CPGs) to assist healthcare professionals in choosing an accessible high quality CPG to advise their practice, and to identify areas for improvement in future versions of current CPGs. METHODS: A systematic review of PubMed, Embase, online CPG databases, and reference lists of included CPGs was carried out. Full text CPGs published no earlier than 1998 reporting evidence based recommendations on VLU diagnosis and management in English were included. CPGs that were only available if purchased were excluded. Two reviewers identified eligible CPGs, extracted data, and assessed the quality independently using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument. Significant scoring discrepancies were discussed with a third reviewer. RESULTS: Fourteen eligible CPGs were identified (1999-2016). The majority of CPGs originated from Europe or North America. Overall, there was good inter-reviewer reliability of scores with an intraclass correlation coefficient of 0.986 (95% confidence interval 0.979-0.991). No single CPG achieved the highest score in all six domains. Significant methodological heterogeneity was observed across VLU CPGs; however, consistently, poor performance was noted in domain 5, concerning CPG applicability. CONCLUSION: Four CPGs were considered of adequate quality for clinical use. Consolidation of efforts to drive high quality, comprehensive VLU CPGs is necessary to reduce the number of and heterogeneity seen in currently published guidelines. Elements of methodological quality are lacking and a structured approach with use of checklists and CPG creation tools, such as AGREE II or others, may bolster rigour in future VLU CPGs. PMID- 30287208 TI - Site and Burden of Lower Limb Atherosclerosis Predicts Long-term Mortality in a Cohort of Patients With Peripheral Arterial Disease. AB - OBJECTIVE/BACKGROUND: Lower limb peripheral arterial disease (PAD) is becoming increasingly common. Lower limb perfusion, as determined by the ankle brachial pressure index (ABPI), is a recognised predictor of overall mortality. The increasing role of non-invasive imaging in patient assessment may aid in the ability to predict poor patient outcomes. METHODS: This study included all patients undergoing a lower limb arterial duplex over a period of 20 months. The site and burden of atherosclerosis within the lower limb was determined using the well validated Bollinger score. Patient demographic data were also collated. The primary outcome measure was all cause mortality. RESULTS: A total of 678 patients were included (median age 74 years). The overall median follow up period was 69.9 months. Of these, 307 patients reached the primary end point, which was death. Independent predictors of all cause mortality included total Bollinger score (odds ratio [OR] 1.11, 95% confidence interval [CI] 1.05-1.18 [p < .001]; OR per 10 points), femoropopliteal Bollinger score (OR 1.34, 95% CI 1.11-1.08 [p = .05]; OR per 10 points), and crural Bollinger score (OR 1.03, 95% CI 1.01-1.03 [p = .03]). There was also a significant association between mortality and age, a prior history of ischaemic heart disease, a history of congestive cardiac failure and chronic renal failure (chronic kidney disease >= 3). Statin and antiplatelet therapy were protective. CONCLUSION: This contemporary study confirms poor long term outcomes still exist in patients with PAD. The site and severity of lower limb atherosclerosis are independent predictors of long-term mortality. PMID- 30287209 TI - Nonagenarians will be the Future Challenge for Vascular Specialists. PMID- 30287210 TI - Alirocumab dosing patterns during 40 months of open-label treatment in patients with heterozygous familial hypercholesterolemia. AB - BACKGROUND: ODYSSEY OLE (NCT01954394) was an open-label extension (OLE) study for patients with heterozygous familial hypercholesterolemia (HeFH) who had completed previous phase 3 clinical trials with alirocumab. Alirocumab dose could be increased or decreased as per physician judgment. OBJECTIVE: To assess how the alirocumab dosing strategy was used by physicians during OLE. METHODS: Patients who entered OLE on a starting dose of alirocumab 75 mg every 2 weeks (Q2W) were included in the analysis (those from FH I, FH II, and LONG TERM trials). Those who completed LONG TERM entered an 8-week washout period before receiving alirocumab 75 mg Q2W at the start of OLE. From week 12, dose adjustment from 75 to 150 mg Q2W, or vice versa, was possible, based on the physician's clinical judgment. RESULTS: In total, 909 patients with HeFH completed the 3 parent studies and were treated during OLE for a duration of up to 40 months. Most patients (56.7%) were maintained on 75 mg Q2W throughout OLE, whereas 43.3% of patients had their dose increased to 150 mg Q2W. The dose was subsequently decreased in 7.4% of the patients in whom alirocumab was initially uptitrated. Overall, treatment-emergent adverse events were similar between those who had received placebo or alirocumab in the parent studies. CONCLUSIONS: In the opinion of physicians, alirocumab 75 mg Q2W enabled over half of patients with HeFH to achieve sufficient low-density lipoprotein cholesterol lowering. PMID- 30287211 TI - Alcohol-Dependent Pulmonary Inflammation: A Role for HMGB-1. AB - Previous studies demonstrate that acute alcohol intoxication significantly impairs lung immune responses, which can lead to the tissue undefended from microbial infection and resulting disease. Data suggest that acute intoxication presents an axis where simultaneously suppressing early pro-inflammatory cytokines while inducing anti-inflammatory signals contribute to alcohol dependent immune suppression in the lung, and thus undeterred microbial replication. Interestingly, alcoholics and those with alcohol use disorder present with increased pneumonia and Acute Respiratory Disease (ARDs), suggesting a more active priming of inflammatory responses in the lungs. There is current research evaluating the acute effects of binge ethanol consumption on adolescents and is of grave concern, though long-term effects of adolescent ethanol binge exposure is less studied. We hypothesize that adolescent binge drinking may prime the individual to severe pulmonary distress, when later challenged by a microbial pathogen. Herein, we evaluate a model of Adolescent Intermittent Ethanol (AIE) exposure to investigate pulmonary pathology after microbial challenge. Ethanol (EtOH) was administered to adolescent mice using a binge exposure schedule and then rested to early adulthood. These mice were then challenged with a sub-lethal intra-nasal inoculation of K. pneumoniae and evaluated for severity of disease. We find that AIE exposure initially activates inflammatory mediators within the lung, which resolves over time. However when challenged with a microbial pathogen after this resolution period, these animals present with more severity of inflammation, pulmonary tissue damage and mortality when challenged with a pulmonary microbial infection. Interestingly, our data suggests a role for alcohol-dependent release of the protein HMGB-1 from host cells, for both morbidity and mortality in our model of microbial-dependent pulmonary inflammation.

AB - Nef is a major pathogenic factor of human and simian immunodeficiency viruses that hijacks protein trafficking through physical interaction with vesicle coats. This alters the subcellular localization of proteins involved in immunity and neutralizes their function. Understanding the structural bases for these interactions could reveal new targets for antiviral intervention. PMID- 30287213 TI - Colchicine reduces platelet aggregation by modulating cytoskeleton rearrangement via inhibition of cofilin and LIM domain kinase 1. AB - INTRODUCTION: Platelets activation/aggregation with subsequent thrombus formation is the main event in the pathophysiology of acute coronary syndrome. Once activated, platelets show an extensive cytoskeleton rearrangement that leads to recruitment of additional platelets to finally cause haemostatic plug formation. Thus, the cytoskeleton plays a pivotal role in this phenomenon. Colchicine (COLC) is an anti-inflammatory drug proven to reduce major cardiovascular events in patients with coronary artery disease. The molecular mechanisms by which COLC exerts these protective effects remain partially still unknown. Since COLC causes disruption of tubulin, a component of cell cytoskeleton, we investigated whether this drug might interfere with platelet aggregation by acting on cytoskeleton rearrangement. METHODS AND RESULTS: Platelets isolated from healthy volunteers were activated with Adenosine Diphosphate (ADP, 20 MUM) Collagen (COLL, 60 MUg/ml) and Thrombin Activating Receptor Peptide (TRAP 25 MUM) with/without COLC 10 MUM pretreatment. After stimulus, aggregation was measured by light aggregometry overtime. Microtubules structure was assessed by immunohistochemistry and key proteins involved in regulation of actin-filament assembly and contractility such as Myosin Phosphatase Targeting subunit (MYPT), LIM domain kinase 1(LIMK1) and cofilin were evaluated by Western Blot analysis. Colchicine pretreatment significantly blunted ADP/COLL/TRAP-induced platelet aggregation (up to 40%). COLC effects appeared mediated by microtubules depolymerization and cytoskeleton disarrangement associated to inactivation of MYPT and LIMK1 that finally interfered with cofilin activity. CONCLUSIONS: Our data indicate that colchicine exerts anti-platelet effects in vitro via inhibition of key proteins involved in cytoskeleton rearrangement, suggesting that its beneficial cardiovascular properties may be due, at least in part, to an inhibitory effect of platelet activity. PMID- 30287214 TI - Association between pregnant women's experience of stress and partners' fly-in fly-out work. AB - BACKGROUND: It is relatively common in Western Australia for men to commute long distances and work away from home for extended periods of time, often referred to as fly-in-fly-out work. Women are particularly susceptible to the effects of stress during pregnancy, and the absence of a partner due to working away could be an additional risk to their wellbeing. While there is little published fly-in fly-out literature, there is evidence that working non-standard hours, more generally, has a negative impact on health and well-being of workers and their families. AIM: To determine if there is an association between pregnant women's report of stress and their partners working fly-in-fly-out, and if so, is there is a differential impact that is dependent on family socioeconomic status. METHODS: Data from a Western Australian pregnancy cohort study were analysed (n=394 families). Couples completed self-report ratings of anxiety, depression, stress, family functioning, and stressful life events. Comparisons were made between three groups: fly-in-fly-out workers, non-fly-in-fly-out regular schedule workers, and non-fly-in-fly-out irregular schedule workers. RESULTS: After controlling for a range of variables, women's stress was significantly associated (p<.05) with their partners working fly-in-fly-out. Neither women's education, partners' occupation nor an interaction between partners' fly-in-fly-out work and partners' occupation were significantly associated with women's stress. CONCLUSION: There is some evidence that the pregnant partners of fly-in-fly-out workers perceive their lives to be more stressful than women whose partner works non-fly-in-fly-out regular schedules. PMID- 30287215 TI - Transcatheter aortic valve replacement outcomes in bicuspid compared to trileaflet aortic valves. AB - AIM: TAVR in patients with bicuspid aortic valves (BAV) is more challenging compared to individuals with trileaflet aortic valves (TAV). BAV have been excluded from the large randomized clinical trials assessing transcatheter aortic valve replacements (TAVR) and has been considered as a relative contraindication to TAVR. To report the outcomes of TAVR in BAV and compare them to TAV in the National Inpatient Sample (NIS). METHODS AND RESULTS: TAVR procedures were identified between 2011 and 2014 in the NIS dataset. Endpoints assessed included in-hospital mortality, periprocedural complications, length of stay and cost. Of 40,604 identified TAVR procedures, 407 (1%) were BAV and the 40,197 (99%) were TAV. Patients with BAV were younger and had a lower comorbidity burden. In hospital mortality (4.89% vs 4.17%, OR: 1.71, 95%CI: 0.57-5.12, P = 0.21), AMI (3.49% vs 3.58%, OR: 1.12, 95%CI: 0.36-3.54, P = 0.85), stroke and TIA (2.49% vs 3.55%, OR: 0.75, 95%CI: 0.18-3.16, P = 0.70), vascular complications (2.39% vs 5.58%, OR:0.47, 95%CI: 0.11-1.93, P = 0.29), major bleeding (16.96% vs 23.50%, OR: 0.63, 95%CI: 0.34-1.17, P = 0.15) and rates of permanent pacemaker (PPM) (9.88% vs 10.88%, OR: 1.19, 95%CI: 0.57-2.51, P = 0.64) were similar in both cohorts. CONCLUSIONS: With multimodality imaging and further improvement in technology, our study demonstrates off-label TAVR should not be considered prohibitive and can be successfully performed for BAV with similar peri procedural outcomes compared to those with TAV. However, there is a need for robust large prospective studies. PMID- 30287217 TI - Editorial: The science to improve neonatal delivery room resuscitation. PMID- 30287216 TI - Nano-TiO2 stability in medium and size as important factors of toxicity in macrophage-like cells. AB - TiO2 along with nano-TiO2 are commonly found in consumer products. In vivo studies have observed an accumulation of nano-TiO2 in macrophages. However, characteristics of nano-TiO2 determining toxicity remain unclear. In our study, the cytotoxic effects of 14 diverse nano-TiO2 on THP-1 macrophage-like cells were measured by 3 cytotoxicity assays (MTS, WST-1 and LDH). Total averaged cytotoxicity was calculated using principal component analysis. Characteristics of all 14 nano-TiO2 included hydrodynamic diameter, zeta potential, shape, polydispersity index (PDI) and concentration; moreover, crystal form, specific surface area and crystallite size were measured for 10 nano-TiO2.The variables affecting cytotoxicity were chosen using LASSO (least absolute shrinkage and selection operator). Except for concentration, PDI in media measured within 1 h after preparation of the nanomaterial dispersion was selected as a variable affecting cytotoxicity: stable dispersion resulted in higher cytotoxic effects. Crystallite size has been shown to have nonlinear effects (particles of sizes between 20 and 60 nm were cytotoxic while smaller and larger ones were not) and thus it has been excluded from LASSO. The shape (particles/fibre) and crystal form did not affect the cytotoxicity. PDI and the nonlinear effect of size could be an explanation for the inconsistencies of the cytotoxicity of nano-TiO2 in various studies. PMID- 30287218 TI - A text mining analysis of medication quality related event reports from community pharmacies. AB - BACKGROUND: Medication errors are estimated to cost $42 billion in annual global treatment costs. Pharmacy-based Patient Safety Organizations (PSO) are tasked with collecting and analyzing incidents, near misses, and unsafe condition reports as one way of engaging pharmacies in quality improvement efforts. Collectively, these reports are referred to as quality related events (QREs). Large-scale analysis of typed narratives from QRE reports across organizations has been a missing component of quality improvement programs. OBJECTIVE: To identify topics within the components of a proposed medication safety event framework contained in the free-text narrative of QRE reports. METHODS: A retrospective, observational analysis of data from a PSOs voluntary reporting system, from January 1, 2011 to December 31, 2014. The dataset contained structured and unstructured data elements. A structural topic model extracted themes from the free-text narrative component of the report. These topics were assigned a human label and mapped onto constructs of the medication safety event framework. RESULTS: A total of 531,555 QREs were analyzed from 1660 pharmacies. 90.6% were near miss and unsafe condition reports. There were 40 topics generated. There were 29 topics identified as QRE types, 3 were identified as contributing factors, and 5 were related to signals/alerts that an incident or near miss had occurred. One topic each was identified as a recovery step and a quality improvement strategy. One topic was not assigned a human label. Examples of topics labeled included incorrect tapering directions, needing to double-check work, and attention-related contributing factor. CONCLUSIONS: The free-text narrative provided novel information compared to the structured fields of the reports. Topics were mapped onto a proposed medication safety event framework to advance knowledge of medication QREs and identify ways to improve medication safety in community pharmacy. Future work may focus on communicating these topics to the pharmacies to improve medication safety efforts.

AB - Autoimmune polyendocrine syndrome type 1 (APS1) is characterized by multiorgan autoimmunity. We aim at characterizing a multi-center Brazilian cohort of APS1 patients by clinical evaluation, searching mutation in the AIRE gene, measuring serum autoantibodies, and investigating correlations between findings. We recruited patients based on the clinical criteria and tested them for AIRE mutations, antibodies against interferon type I and interleukins 17A, 17F and 22. We identified 12 unrelated families (13 patients) with typical signs of APS1 in the proband, and the screening of relatives recognized an asymptomatic child. Candidiasis was present in all cases, and 19 other manifestations were observed. All patients carried one of 10 different mutations in AIRE, being 3 new ones, and were positive for anti-interferon type I serum antibody. Anti-interleukin-17A levels inversely correlated with the number of manifestations in each patient. This negative correlation may suggest a protective effect of anti-interleukin-17A with a potential therapeutic application. PMID- 30287220 TI - Low density lipoprotein oxidation by ferritin at lysosomal pH. AB - Oxidation of low density lipoprotein (LDL) has been proposed to be involved in the pathogenesis of atherosclerosis. We have previously shown that LDL can be oxidised by iron in lysosomes. As the iron-storage protein ferritin might enter lysosomes by autophagy, we have investigated the ability of ferritin to catalyse LDL oxidation at lysosomal pH. LDL was incubated with ferritin at 37 degrees C and pH 4.5 and its oxidation monitored spectrophotometrically at 234 nm by the formation of conjugated dienes and by measuring oxidised lipids by HPLC or a tri iodide assay. Iron released from ferritin was measured using the ferrous iron chelator bathophenanthroline and by ultrafiltration followed by atomic absorption spectroscopy. LDL was oxidised effectively by ferritin (0.05-0.2 MUM). The oxidation at lysosomal pH (pH 4.5) was much faster than at pH 7.4. Ferritin increased cholesteryl linoleate hydroperoxide, total lipid hydroperoxides and 7 ketocholesterol. Iron was released from ferritin at acidic pH. The iron chelators, diethylenetriaminepentaacetate and EDTA, and antioxidant N,N'-diphenyl p-phenylenediamine inhibited the oxidation considerably, but not entirely. The antioxidant tempol did not inhibit the initial oxidation of LDL, but inhibited its later oxidation. Cysteamine, a lysosomotropic antioxidant, inhibited the initial oxidation of LDL in a concentration-dependent manner, however, the lower concentrations exhibited a pro-oxidant effect at later times, which was diminished and then abolished as the concentration increased. These results suggest that ferritin might play a role in lysosomal LDL oxidation and that antioxidants that accumulate in lysosomes might be a novel therapy for atherosclerosis. PMID- 30287221 TI - The deuridylylation activity of Herbaspirillum seropedicae GlnD protein is regulated by the glutamine:2-oxoglutarate ratio. AB - The nitrogen metabolism of Proteobacteria is controlled by the general Ntr system in response to nitrogen quality and availability. The PII proteins play an important role in this system by modulating the cellular metabolism through physical interaction with protein partners. Herbaspirillum seropedicae, a nitrogen-fixing bacterium, has two PII proteins paralogues, GlnB and GlnK. The interaction of H. seropedicae PII proteins with its targets is regulated by allosteric ligands and by reversible post-translational uridylylation. Both uridylylation and deuridylylation reactions are catalyzed by the same bifunctional enzyme, GlnD. The mechanism of regulation of GlnD activity is still not fully understood. Here, we characterized the regulation of deuridylylation activity of H. seropedicae GlnD in vitro. To this purpose, fully modified PII proteins were submitted to kinetics analysis of its deuridylylation catalyzed by purified GlnD. The deuridylylation activity was strongly stimulated by glutamine and repressed by 2-oxoglutarate and this repression was strong enough to overcome the glutamine stimulus of enzymatic activity. We also constructed and analyzed a truncated version of GlnD, lacking the C-terminal regulatory ACT domains. The GlnDDeltaACT protein catalyzed the futile cycle of uridylylation and deuridylylation of PII, regardless of glutamine and 2-oxoglutarate levels. The results presented here suggest that GlnD can sense the glutamine:2-oxoglutarate ratio and confirm that the ACT domains of GlnD are the protein sensors of environment clues of nitrogen availability. PMID- 30287222 TI - Interplay between alpha-synuclein amyloid formation and membrane structure. AB - Amyloid formation is a pathological hallmark of many neurodegenerative diseases, including Alzheimer's, Parkinson's, and Huntington's. While it is unknown how these disorders are initiated, in vitro and cellular experiments confirm the importance of membranes. Ubiquitous in vivo, membranes induce conformational changes in amyloidogenic proteins and in some cases, facilitate aggregation. Reciprocally, perturbations in the bilayer structure can be induced by amyloid formation. Here, we review studies in the last 10 years describing alpha synuclein (alpha-syn) and its interactions with membranes, detailing the roles of anionic and zwitterionic lipids in aggregation, and their contribution to Parkinson's disease. We summarize the impact of alpha-syn - comparing monomeric, oligomeric, and fibrillar forms - on membrane structure, and the effect of membrane remodeling on amyloid formation. Finally, perspective on future studies investigating the interplay between alpha-syn aggregation and membranes is discussed. This article is part of a Special Issue entitled: Amyloids. PMID- 30287224 TI - Impact of Multifocality and Multilocation of Positive Surgical Margin After Radical Prostatectomy on Predicting Oncological Outcome. AB - OBJECTIVE: To assess the impact of focality and location of positive surgical margins (PSM) on long-term outcomes after radical prostatectomy (RP) for prostate cancer (PCa), including biochemical recurrence (BCR), metastasis and overall mortality. PATIENTS AND METHODS: From a total of 2796 cases of RP between 1993 and 2007 in our single hospital, 476 cases with PSMs were identified and included in this study. PSM location was categorized into apex, peripheral, and bladder neck. Survival was estimated using the Kaplan-Meier method. Cox proportional hazard regression models were used to analyze the impact of PSM focality and location status on oncologic survival. RESULTS: Of these 476 cases with PSMs, 335 (70.4%) cases were with single focal (sF) PSMs and 141 (29.6%) cases were with multifocal (mF) PSMs. Furthermore, 406 (85.3%) cases were found to have single location (sL) PSMs, and 70 (14.7%) cases were with multilocation (mL) PSMs. The median follow-up was 12.9 years. mF-PSMs and mL-PSMs showed significant impact on increased BCR risk on univariate analysis, and mL-PSMs remained significant on multivariate analysis (P = .048). Furthermore, the combination of multifocality and multilocation showed added prognostic value on predicting BCR-free survival, but not on metastasis-free survival or overall survival. CONCLUSION: The presence of mF-PSMs and mL-PSMs, and especially the combination of both, demonstrated significant impact on BCR prognosis. Patients with apex sLsF-PSMs were less likely to have BCR when compared with all those with non-apex sLsF-PSMs. These results should be considered when evaluating patients for adjuvant therapy. PMID- 30287223 TI - Updated Recommendations on the Diagnosis, Management, and Clinical Trial Eligibility Criteria for Patients With Renal Medullary Carcinoma. AB - Renal medullary carcinoma (RMC) is one of the most aggressive renal cell carcinomas. It predominantly afflicts young adults and adolescents with sickle cell trait and other sickle hemoglobinopathies, and is refractory to targeted and antiangiogenic therapies used in patients with clear-cell renal cell carcinoma. Platinum-based cytotoxic chemotherapy is the mainstay for RMC treatment. On the basis of recent advances in the diagnosis, management, and clinical trial development for RMC, a panel of experts met in October 2017 and developed updated consensus recommendations to inform clinicians, researchers, and patients. Because RMC often aggressively recurs while patients are still recovering from nephrectomy, upfront chemotherapy should be considered for most patients, including those with localized disease. After safety and dosing information has been established in adults, phase II and III trials enrolling patients with RMC should allow patients aged 12 years and older to be accrued. Patients with the very rare unclassified renal cell carcinoma with medullary phenotype variant should be included in RMC trials. Medical providers should be aware that RMC can afflict subjects of all races, and not only those of African descent, and that the presence of sickle cell trait, or of other sickle hemoglobinopathies, can affect drug responses and toxicity. PMID- 30287226 TI - A standardized approach to the evaluation of antivirals against DNA viruses: Orthopox-, adeno-, and herpesviruses. AB - The search for new compounds with a broad spectrum of antiviral activity is important and requires the evaluation of many compounds against several distinct viruses. Researchers attempting to develop new antiviral therapies for DNA virus infections currently use a variety of cell lines, assay conditions and measurement methods to determine in vitro drug efficacy, making it difficult to compare results from within the same laboratory as well as between laboratories. In this paper we describe a common assay platform designed to facilitate the parallel evaluation of antiviral activity against herpes simplex virus type 1, herpes simplex virus type 2, varicella-zoster virus, cytomegalovirus, vaccinia virus, cowpox virus, and adenovirus. The automated assays utilize monolayers of primary human foreskin fibroblast cells in 384-well plates as a common cell substrate and cytopathic effects and cytotoxicity are quantified with CellTiter Glo. Data presented demonstrate that each of the assays is highly robust and yields data that are comparable to those from other traditional assays, such as plaque reduction assays. The assays proved to be both accurate and robust and afford an in depth assessment of antiviral activity against the diverse class of viruses with very small quantities of test compounds. In an accompanying paper, we present a standardized approach to evaluating antivirals against lymphotropic herpesviruses and polyomaviruses and together these studies revealed new activities for reference compounds. This approach has the potential to accelerate the development of broad spectrum therapies for the DNA viruses. PMID- 30287227 TI - A standardized approach to the evaluation of antivirals against DNA viruses: Polyomaviruses and lymphotropic herpesviruses. AB - The search for new compounds with a broad spectrum of antiviral activity is important and requires the evaluation of many compounds against several distinct viruses. Researchers attempting to develop new antiviral therapies for DNA virus infections currently use a variety of cell lines, assay conditions and measurement methods to determine in vitro drug efficacy, making it difficult to compare results from within the same laboratory as well as between laboratories. In this paper, we describe the assessment of antiviral activity of a set of nucleoside analogs against BK polyomavirus, JC polyomavirus, Epstein-Barr virus, human herpesvirus 6B, and human herpesvirus 8 in an automated 384-well format and utilize qPCR assays to measure the accumulation of viral DNA. In an accompanying paper, we present a standardized approach to evaluating antivirals against additional herpesviruses, orthopoxviruses, and adenovirus. Together, they reveal new activities for reference compounds and help to define the spectrum of antiviral activity for a set of nucleoside analogs against a set of 12 DNA viruses that infect humans including representative human herpesviruses, orthopoxviruses, adenoviruses, and polyomaviruses. This analysis helps provide perspective on combinations of agents that would help provide broad coverage of significant pathogens in immunocompromised patients as well as against emerging infections. PMID- 30287228 TI - Implementation of national screening guidelines for gestational diabetes: A national survey of maternity units in England. AB - AIMS: To describe national implementation of gestational diabetes (GDM) risk factor based screening guidelines, and barriers to implementation relating to maternal body mass index (BMI). METHODS: National online survey of NHS Trusts offering maternity services in England. A questionnaire was emailed to clinical staff involved in care of pregnant women assessing compliance with NICE guidelines for risk-factor based screening, BMI thresholds for offering OGTT and barriers to offering OGTT to women with BMI >= 30 kg/m2. RESULTS: Health professionals from 113 (84%) of NHS Trusts in England responded to the survey. Most Trusts (81%) offered OGTT at 26-28 weeks gestation to women with selected risk factors for GDM. However, almost 40% of Trusts were not fully compliant with NICE screening criteria for all risk factors, mainly due to not offering OGTT to women with previous GDM (25% of Trusts), BMI >= 30 kg/m2 or ethnic minority groups (22% of Trusts). The main barriers to compliance with the BMI threshold were lack of capacity, resource and funding given the high prevalence of maternal obesity. Forty one percent of Trusts used diagnostic thresholds for GDM which differed from NICE recommendations. CONCLUSIONS: Additional resources are required for NHS Trusts to fully implement and sustain risk-factor screening, especially for women with previous GDM, BMI >= 30 kg/m2 and ethnic minority groups. PMID- 30287229 TI - Sex- and age-related differences of metabolic parameters in impaired glucose metabolism and type 2 diabetes compared to normal glucose tolerance. AB - AIMS: This study analysed potential sex differences in glucose metabolism of European subjects with different degrees of glucose tolerance impairment. METHODS: Subjects with impaired glucose metabolism, IGM (n = 735), or type 2 diabetes, T2DM (n = 415), were compared to subjects with normal glucose tolerance, NGT (n = 422), with similar BMI. For both males (M) and females (F), 50 years threshold was used for estimation of menopausal/andropausal state. Subjects underwent 75-g OGTT for measurements of insulin sensitivity (OGIS), beta cell function (insulinogenic index, IGIC), and overall metabolic condition, disposition index (DI). RESULTS: In IGM, OGIS did not change with age in both sexes, whereas marked reduction of IGIC was seen in F (p = 0.0003). In T2DM, again OGIS did not change with age, but M >= 50 yrs had reduced IGIC and DI (p < 0.002) compared to M < 50 yrs. CONCLUSIONS: IGM did not reveal relevant changes of insulin resistance with age, but early phase insulin release deteriorated, with higher change in women. T2DM men featured age-related deterioration of glucose metabolism. In women, sex advantage seen in NGT vanished in T2DM, since glucose metabolism was overall not different than in men, both young and elderly. PMID- 30287230 TI - Impact of sertraline on weight, waist circumference and glycemic control: A prospective clinical trial on depressive diabetic type 2 patients. AB - AIM: Depression is prevalent in patients with type 2 diabetes. It may have a negative impact on the management of diabetes mellitus and could affect weight. The main aim of the investigation was to evaluate the effect of antidepressant treatment (sertraline) on anthropometric variables and glycemic control in depressed type 2 diabetic patients. METHODS: Thirty three type 2 diabetic outpatients depressed received open-label sertraline therapy for up to 12 weeks. Clinical outcome measures included the 17-item Hamilton depression rating. Changes in the anthropometrics variables were evaluated by measuring weight, waist circumference and by calculating body mass index at three, six and 12 weeks of treatment. In addition, fasting, postprandial plasma glucose level, glycosylated hemoglobin-A 1C measures, lipid and renal profile were obtained before and during sertraline therapy. RESULTS: Weight decreased significantly ( 2kg; p=0.000) and body mass index decreased from 30.41kg/m2 to 29.6kg/m2 (p=0.000). Patients lost on average seven centimeters in waist circumference (p=0.000). We also observed a modest, non-significant reduction in fasting, postprandial and glycosylated hemoglobin. We observed a significant reduction in mean score according to the Hamilton depression scale (p=0.000) CONCLUSION: Our study results suggested that sertraline produced a benefic effect on weight, body mass index and waist circumference at 12-week follow up. PMID- 30287231 TI - Strategy for performing treponemal tests in reverse-sequence algorithms of syphilis diagnosis. AB - OBJECTIVES: In South Korea, automated T. pallidum Latex Agglutination (TPLA) based on turbidoimmunoassays and immunochromatographic assay (ICA) are widely used for syphilis diagnosis. However, there is sparse data on the validation of these assays in the reverse-sequence algorithm setting. METHODS: We assessed 551 specimens submitted for syphilis testing. We compared varying reverse-sequence algorithms using combinations of the Cobas Syphilis EIA (Roche Diagnostics, Mannheim, Germany), Mediace TPLA (Sekisui Medical Co., Tokyo, Japan), TPPA (Fujirebio Inc., Tokyo, Japan), and SD Bioline ICA (Standard Diagnostic, Yongin, Korea). We also evaluated modified algorithms incorporating a cut off of high specificity for EIA and TPLA using receiver operating characteristic curves. RESULTS: The agreement was almost perfect between EIA and TPLA (Kappa, 0.953) and strong between TPPA and ICA (Kappa, 0.887). Among TPPA positive and ICA negative specimens, 67% of the specimens were from individuals with syphilis histories. Compared to EIA/RPR/TPPA, the agreement with EIA/RPR/ICA, TPLA/RPR/TPPA and TPLA/RPR/ICA were almost perfect (Kappa, 0.930, 0.995 and 0.914, respectively). When a cut off of 95% specificity was applied, the number of TPPA tests could be reduced by 44% and 40% in EIA and TPLA, respectively. CONCLUSIONS: TPLA showed almost perfect agreement with EIA and that it could be used in the site of EIA in a reverse sequence algorithm. ICA showed a lower detection rate than TPPA as a 2nd treponemal test and should be used with caution. With cut offs of higher specificity, more efficient reverse-sequence algorithms can be made possible. PMID- 30287232 TI - Two observational studies examining the effect of a social norm and a health message on the purchase of vegetables in student canteen settings. AB - There is some evidence from laboratory-based studies that descriptive social-norm messages are associated with increased consumption of vegetables, but evidence of their effectiveness in real-world settings is limited. In two observational field studies taking an ecological approach, a vegetable-related social norm (e.g. "Did you know that most students here choose to eat vegetables with their meal?"), and a health message (e.g. "Did you know that students who choose to eat vegetables have a lower risk of heart disease?") were displayed in two different student canteens. Purchases were observed during three stages: baseline, intervention (when the posters were displayed) and immediate post-intervention (when the posters had been removed). Study 1 (n = 7598) observed the purchase of meals containing a portion of vegetables and Study 2 (n = 4052) observed the purchase of side portions of vegetables. In Study 1, relative to baseline, the social norms intervention was associated with an increase in purchases of vegetables (from 63% to 68% of meals; OR = 1.24, CI = 1.03-1.49), which was sustained post intervention (67% of meals; OR = 0.96, CI = 0.80-1.15). There was no effect of the health message (75% of meals at baseline, and 74% during the intervention; OR = 0.98, CI = 0.83-1.15). In Study 2, relative to baseline, there was an effect of both the social norm (22.9% of meals at baseline, rising to 32.5% during the intervention; OR = 1.62, CI = 1.27-2.05) and health message (rising from 43.8% at baseline to 52.8%; OR = 0.59, CI = 0.46-0.75). The increase was not sustained post-intervention for the social norm intervention (22.1%; OR = 0.59, CI = 0.46 0.75), but was sustained for the health intervention (48.1%; OR = 0.83, CI = 0.67 1.02). These results support further testing of the effectiveness of such messages in encouraging healthier eating and indicate the need for larger-scale testing at multiple sites using a randomised-controlled design. PMID- 30287233 TI - Effect of efferocytosis of apoptotic mesenchymal stem cells (MSCs) on C57BL/6 peritoneal macrophages function. AB - Phagocytic clearance of apoptotic cells (Efferocytosis) could affect the polarization of macrophages and promote M2 anti-inflammatory and regulatory phenotype and function. Here we tested the hypothesis that efferocytosis of apoptotic Adipose-Derived Mesenchymal Stem Cells (AD-MSCs) promotes macrophage M2 polarization. In this study, Macrophages were incubated with apoptotic MSCs and after 48 h interleukin-10 (IL-10), transforming growth factor-alpha (TNFalpha), and nitric oxide (NO) production were measured. Furthermore, phagocytosis ability and arginase activity were analyzed. The results showed that apoptotic MSCs could reduce TNFalpha and NO production, and increase IL-10 levels. Moreover, arginase activity and phagocytosis ability were also increased in tested macrophages compared to controls. In Conclusion efferocytosis of AD-MSCs can alter the macrophages phenotype toward regulatory and anti-inflammatory phenotype. PMID- 30287225 TI - Sphingolipids in neurodegeneration (with focus on ceramide and S1P). AB - For many decades, research on sphingolipids associated with neurodegenerative disease focused on alterations in glycosphingolipids, particularly glycosylceramides (cerebrosides), sulfatides, and gangliosides. This seemed quite natural since many of these glycolipids are constituents of myelin and accumulated in lipid storage diseases (sphingolipidoses) resulting from enzyme deficiencies in glycolipid metabolism. With the advent of recognizing ceramide and its derivative, sphingosine-1-phosphate (S1P), as key players in lipid cell signaling and regulation of cell death and survival, research focus shifted toward these two sphingolipids. Ceramide and S1P are invoked in a plethora of cell biological processes participating in neurodegeneration such as ER stress, autophagy, dysregulation of protein and lipid transport, exosome secretion and neurotoxic protein spreading, neuroinflammation, and mitochondrial dysfunction. Hence, it is timely to discuss various functions of ceramide and S1P in neurodegenerative disease and to define sphingolipid metabolism and cell signaling pathways as potential targets for therapy. PMID- 30287234 TI - Phloretin cytoprotection and toxicity. AB - Phloretin (Phl) is a dihydrochalcone flavonoid with significant cytoprotective properties; e.g., free radical trapping, electrophile scavenging. Based on this, it has been suggested that Phl might be useful in the treatment of pathogenic processes and prevention of drug toxicities. Therefore, we determined the ability of Phl to provide route- and dose-dependent hepatoprotection in a mouse model of acetaminophen (APAP) overdose. Intraperitoneal (i.p.) administration of Phl produced a bimodal effect; i.e., the highest dose (2.40 mmol/kg) did not prevent APAP-induced lethality, whereas lower doses (0.2-0.4 mmol/kg) afforded modest hepatoprotection. When given alone, the highest i.p. Phl dose was lethal within 24 h, whereas the lower doses were not toxic. Oral Phl (0.40-2.40 mmol/kg) did not prevent APAP-induced hepatotoxicity. The highest oral dose given alone (2.4 mmol/kg) produced 64% lethality, whereas lower doses were not lethal. This toxicity profile was reflected in a study using APAP-exposed isolated mouse hepatocytes, which showed that the Phl pharmacophores, 1,3,5 trihydroxyacetophenone (PG) and 2',4',6'-trihydroxyacetophenone (THA) where protective. Corroborative cell free studies showed that polyphenol protectants prevented glutathione loss mediated by the APAP metabolite, N-acetyl-p benzoquinone imine (NAPQI). Thus, in spite of possessing cytoprotective attributes, Phl was generally toxic in our APAP models. These and earlier findings suggest that Phl is not a candidate for drug design. In contrast, we have found that the enol-forming pharmacophores, THA and PG, are potential platforms for pharmacotherapeutic development.

AB - Cyclohexanone monooxygenase (CHMO) uses NADPH and O2 to insert oxygen into an array of (a)cyclic ketones to form esters or lactones. Herein, the role of two conserved active site residues (R327 and D57) in controlling the binding mode of NADP(H) was investigated. Wild type CHMO elicits a kinetic isotope effect (KIE) of 4.7 +/- 0.1 and 1.1 +/- 0.1 with 4(R)-[4-2H]NADPH and 4(S)-[4-2H]NADPH, respectively, consistent with transfer of the proR hydrogen to FAD. Strikingly, the R327K variant appears to lack stereospecificity for hydride transfer as a KIE of 1.5 +/- 0.1 and 2.5 +/- 0.1 was observed for the proR and proS deuterated forms of NADPH. 1H NMR of the NADP+ products confirmed that the R327K variant abstracts either the proR or proS hydrogen from NADPH. While the D57A variant retained stereospecificity for the proR hydrogen, this substitution resulted in slow decomposition of the C4a-peroxyflavin intermediate in the presence of cyclohexanone. Based on published structures of a related flavin monooxygenase, we suggest that elimination of the hydrogen bond between D57 and R327 in the D57A variant causes R327 to adopt a substrate-induced conformation that slows substrate access to the active site, thereby prolonging the lifetime of the C4a peroxyflavin intermediate. PMID- 30287238 TI - Optimal Therapy for Unstable Pulmonary Embolism. AB - There are no randomized controlled trials of thrombolytic therapy, pulmonary embolectomy, or inferior vena cava (IVC) filters in patients with unstable pulmonary embolism (those in shock or on ventilator support). Yet, there are many investigations of these treatments based on retrospective cohort studies using administrative data from large government and commercial databases. Extensive data from these cohort studies showed that thrombolytic therapy resulted in the lowest in-hospital all-cause mortality. The results of thrombolytic therapy were greatly improved if IVC filters were added. In fact, IVC filters decreased in hospital all-cause mortality with anticoagulants alone or pulmonary embolectomy as well as thrombolytic therapy in adults of all ages with unstable pulmonary embolism. The IVC filters reduced mortality only if inserted on the day of admission or the next day, while the patients were unstable and in a fragile condition. We conclude that the best treatment for patients with unstable pulmonary embolism is thrombolytic therapy combined with an IVC filter inserted during the period of fragility, while the patient is unstable, and this treatment is indicated in all unstable patients irrespective of age. PMID- 30287237 TI - Piperine, an alkaloid inhibiting the super-relaxed state of myosin, binds to the myosin regulatory light chain. AB - Piperine, an alkaloid from black pepper, was found to inhibit the super-relaxed state (SRX) of myosin in fast-twitch skeletal muscle fibers. In this work we report that the piperine molecule binds heavy meromyosin (HMM), whereas it does not interact with the regulatory light chain (RLC)-free subfragment-1 (S1) or with control proteins from the same muscle molecular machinery, G-actin and tropomyosin. To further narrow down the location of piperine binding, we studied interactions between piperine and a fragment of skeletal myosin consisting of the full-length RLC and a fragment of the heavy chain (HCF). The sequence of HCF was designed to bind RLC and to dimerize via formation of a stable coiled coil, thus producing a well-folded isolated fragment of the myosin neck. Both chains were co expressed in Escherichia coli, the RLC/HCF complex was purified and tested for stability, composition and binding to piperine. RLC and HCF chains formed a stable heterotetrameric complex (RLC/HCF)2 which was found to bind piperine. The piperine molecule was also found to bind isolated RLC. Piperine binding to RLC in (RLC/HCF)2 altered the compactness of the complex, suggesting that the mechanism of SRX inhibition by piperine is based on changing conformation of the myosin.

AB - INTRODUCTION AND OBJECTIVES: The resting 12-lead electrocardiogram (ECG) has been used in the evaluation of young asymptomatic individuals to detect pre-existing heart disease, but systematic ECG use is controversial and there are no data on this population in our environment. We aimed to determine the prevalence and spectrum of electrocardiographic findings in a population of secondary school students. METHODS: We conducted an observational, cross-sectional study of resting ECG findings in all 13 to 14-year-old secondary school students in a region of the province of Gerona between 2009 and 2017. ECG findings were classified into 3 groups according to the modified criteria of Corrado et al.: normal ECG findings, ECG findings suggestive of adaptive changes, and pathologic findings. Students with pathologic ECG findings were referred to a tertiary hospital, and complementary tests were performed according to a pre-established protocol. RESULTS: A total of 1911 ECGs were obtained, with a participation rate of 79% of all high school students. In all, 1321 students (69%) had a normal ECG, 554 (29%) showed ECG findings suggestive of adaptive changes, and 36 (2%) had pathologic ECG findings. Among the group with pathologic findings, 5 (14%) had cardiovascular disease. The prevalence of heart disease in this group of asymptomatic secondary school students was 0.3%. CONCLUSIONS: One third of the students had ECG findings that were mostly suggestive of physiological adaptation. One seventh of the students with pathologic ECG findings had pre existing heart disease, although the overall prevalence of pre-existing heart disease was low.

AB - INTRODUCTION AND OBJECTIVES: The cardiovascular benefits of the Mediterranean diet have usually been assessed under assumptions of ad libitum total energy intake (ie, no energy restriction). In the recently launched PREDIMED-Plus, we conducted exploratory analyses to study the baseline associations between adherence to an energy-restricted Mediterranean diet (MedDiet) and the prevalence of cardiovascular risk factors (CVRF). METHODS: Cross-sectional assessment of all PREDIMED-Plus participants (6874 older adults with overweight/obesity and metabolic syndrome) at baseline. The participants were assessed by their usual primary care physicians to ascertain the prevalence of 4 CVRF (hypertension, obesity, diabetes, and dyslipidemia). A 17-point PREDIMED-Plus score was used to measure adherence to the MedDiet. Multivariable models were fitted to estimate differences in means and prevalence ratios for individual and clustered CVRF. RESULTS: Better adherence to a MedDiet pattern was significantly associated with lower average triglyceride levels, body mass index, and waist circumference. Compared with low adherence (<= 7 points in the 17-point score), better adherence to the MedDiet (11-17 points) showed inverse associations with hypertension (prevalence ratio=0.97; 95%CI, 0.94-1.00) and obesity (prevalence ratio=0.96; 95%CI, 0.92-1.00), but positive associations with diabetes (prevalence ratio=1.19; 95%CI, 1.07-1.32). Compared with the lowest third of adherence, women in the upper third showed a significantly lower prevalence of the clustering of 3 or more CVRF (prevalence ratio=0.91; 95%CI, 0.83-0.98). CONCLUSIONS: Among participants at high cardiovascular risk, better adherence to a MedDiet showed significant inverse associations with CVRF among women, and improved lipid profiles and adiposity measures. This trial was registered in 2014 at the International Standard Randomized Controlled Trial Registry (ISRCTN89898870). PMID- 30287242 TI - The transcriptomic expression of pattern recognition receptors: Insight into molecular recognition of various invading pathogens in Oyster Crassostrea gigas. AB - Pattern recognition receptors (PRRs) are essential in recognizing specific pathogen-associated molecular patterns (PAMPs) on microbes and triggering responses to eliminate the invading pathogens. Previous genomic studies have revealed a great number of PRR genes in the Pacific oyster Crassostrea gigas, a sessile and filter-feeder marine bivalve belonging to the phylum Mollusca. On the survey of PRRs in the assembly oyster reference genome version 9, a total of 1084 PRRs were identified, which were composed of at least 12 gene families. Some of the gene families were significantly expanded, including C-type lectins (CTLs), fibrinogen-related proteins (FREPs), scavenger receptor cysteine-rich repeat protein (SRCRs), leucine-rich repeat (LRR)-only proteins (LRRops), and especially C1q domain-containing proteins (C1qDCs). The transcriptomic profiles of these abundant PRRs in response to PAMP treatments were investigated by RNA-Seq using the SOLiD EZ BeadTM system. Compared to the control library, there were 6,655, 7,273, 7,593, 6,830, 6687 and 8250 differentially expressed genes in the haemocytes of oysters in response to lipopolysaccharide (LPS) stimulation for 6 h, 12 h and 24 h, and peptidoglycan (PGN), glucan (GLU) and poly I:C (IC) stimulation for 12 h, respectively. After stimulation for 12 h, there were 134, 97, 114 and 159 genes up-regulated in the LPS, PGN, GLU and IC library, respectively. Most of the gene families involved in immune response towards PAMPs were C1qDCs, CTLs and FREPs, while only a few members of LRR and immunoglobin containing proteins (LRRIGs), retinoic acid-inducible gene I [RIG-I]-like receptors (RLRs) and Toll like receptors (TLRs) were up-regulated. After LPS stimulation, the expression level of 258 non-redundant PRR genes in oyster haemocytes increased significantly with different expression pattern, and most of them were C1qDCs, CTLs, LRRops and FREPs. The transcriptomic analyses indicated that there was a dynamic and orchestrated specific expression regulation of numerous PRR genes in response to pathogen invasion. The expanded PRR gene family members were differentiated with more specific functional responses to certain PAMPs rather than the versatile ones. Based on the different expression pattern during the LPS stimulation, the oyster PRRs could be assigned into three consecutive steps in the response against pathogen invading. All the results would provide useful information for future studies of oyster PRRs and deep insight into the researches on invertebrate innate immunity. PMID- 30287244 TI - Characterization of an RNase with two catalytic centers. Human RNase6 catalytic and phosphate-binding site arrangement favors the endonuclease cleavage of polymeric substrates. AB - BACKGROUND: Human RNase6 is a small cationic antimicrobial protein that belongs to the vertebrate RNaseA superfamily. All members share a common catalytic mechanism, which involves a conserved catalytic triad, constituted by two histidines and a lysine (His15/His122/Lys38 in RNase6 corresponding to His12/His119/Lys41 in RNaseA). Recently, our first crystal structure of human RNase6 identified an additional His pair (His36/His39) and suggested the presence of a secondary active site. METHODS: In this work we have explored RNase6 and RNaseA subsite architecture by X-ray crystallography, site-directed mutagenesis and kinetic characterization. RESULTS: The analysis of two novel crystal structures of RNase6 in complex with phosphate anions at atomic resolution locates a total of nine binding sites and reveals the contribution of Lys87 to phosphate-binding at the secondary active center. Contribution of the second catalytic triad residues to the enzyme activity is confirmed by mutagenesis. RNase6 catalytic site architecture has been compared with an RNaseA engineered variant where a phosphate-binding subsite is converted into a secondary catalytic center (RNaseA-K7H/R10H). CONCLUSIONS: We have identified the residues that participate in RNase6 second catalytic triad (His36/His39/Lys87) and secondary phosphate-binding sites. To note, residues His39 and Lys87 are unique within higher primates. The RNaseA/RNase6 side-by-side comparison correlates the presence of a dual active site in RNase6 with a favored endonuclease-type cleavage pattern. GENERAL SIGNIFICANCE: An RNase dual catalytic and extended binding site arrangement facilitates the cleavage of polymeric substrates. This is the first report of the presence of two catalytic centers in a single monomer within the RNaseA superfamily. PMID- 30287243 TI - ALDH1-positive intratumoral stromal cells indicate differentiated epithelial-like phenotype and good prognosis in prostate cancer. AB - Aldehyde dehydrogenase 1 (ALDH1) characterizes tumor-initiating cells in solid tumors; however, little is known about its expression in intratumoral stromal cells. Herein, we aimed to dissect its potential dual relevance in prostate cancer (PCa). ALDH1 expression was evaluated immunohistochemically in tumor and stromal cells in primary PCa and metastases. It was correlated to clinico pathologic parameters, patients' outcome, and selected proteins (CK5/6, CK14, CK8/18, CK19, EpCAM, Ki-67, E-cadherin, N-cadherin, and vimentin). ALDH1 protein was detected in tumor and stromal cells in 16% and 67% of 348 primary PCa, respectively. Tumor cell ALDH1 expression was associated with advanced T stage (P = 0.009), higher Gleason score (P = 0.016), shorter time to biochemical recurrence (TBR P = 0.010) and CK14 expression (P = 0.023). Stromal cell ALDH1 expression correlated to lower T stage (P = 0.008) and Gleason score (P = 0.016), N0 stage (P = 0.017), and longer TBR (P = 0.017). It occurred to be an independent predictor of good prognosis in the subgroup of d'Amico high-risk patients (multivariate analysis, P = 0.050). ALDH1-positive stromal cells were found in tumors characterized frequently by CK8/18 (P = 0.033) or EpCAM expression (P < 0.001) and rarely by epithelial-mesenchymal transition defined as CK8/18(-)vimentin(+) phenotype (P = 0.003). ALDH1-positive tumor and stromal cells were detected in 33% and 41% of hormone naive lymph node metastases (n = 63), 52% and 24% of castration resistant bone metastases, as well as 89% and 28% of castration resistant visceral metastases (n = 21), respectively. We have determined that contrary to tumor cell ALDH1, the presence of stromal ALDH1 is associated with epithelial phenotype of primary PCa, improved clinical outcome, and is less frequent in PCa metastases. PMID- 30287245 TI - Audiovisual multisensory integration in individuals with autism spectrum disorder: A systematic review and meta-analysis. AB - An ever-growing literature has aimed to determine how individuals with autism spectrum disorder (ASD) differ from their typically developing (TD) peers on measures of multisensory integration (MSI) and to ascertain the degree to which differences in MSI are associated with the broad range of symptoms associated with ASD. Findings, however, have been highly variable across the studies carried out to date. The present work systematically reviews and quantitatively synthesizes the large literature on audiovisual MSI in individuals with ASD to evaluate the cumulative evidence for (a) group differences between individuals with ASD and TD peers, (b) correlations between MSI and autism symptoms in individuals with ASD and (c) study level factors that may moderate findings (i.e., explain differential effects) observed across studies. To identify eligible studies, a comprehensive search strategy was employed using the ProQuest search engine, PubMed database, forwards and backwards citation searches, direct author contact, and hand-searching of select conference proceedings. A significant between-group difference in MSI was evident in the literature, with individuals with ASD demonstrating worse audiovisual integration on average across studies compared to TD controls. This effect was moderated by mean participant age, such that between-group differences were more pronounced in younger samples. The mean correlation between MSI and autism and related symptomatology was also significant, indicating that increased audiovisual integration in individuals with ASD is associated with better language/communication abilities and/or reduced autism symptom severity in the extant literature. This effect was moderated by whether the stimuli were linguistic versus non-linguistic in nature, such that correlation magnitudes tended to be significantly greater when linguistic stimuli were utilized in the measure of MSI. Limitations and future directions for primary and meta-analytic research are discussed. PMID- 30287246 TI - Counseling and referrals for women with unplanned pregnancies at publicly funded family planning organizations in Texas. AB - OBJECTIVES: To compare pregnancy options counseling and referral practices at state- and Title X-funded family planning organizations in Texas after enforcement of a policy restricting abortion referrals for providers participating in state-funded programs, which differed from Title X guidelines to provide referrals for services upon request. STUDY DESIGN: Between November 2014 and February 2015, we conducted in-depth interviews with administrators at publicly funded family planning organizations in Texas about how they integrated primary care and family planning services, including pregnancy options counseling and referrals for unplanned pregnancies. We conducted a thematic analysis of transcripts related to organizations' pregnancy options counseling and referral practices, and compared themes across organizations that did and did not receive Title X funding. RESULTS: Of the 37 organizations with transcript segments on options counseling and referrals, 15 received Title X and 22 relied on state funding only. All Title X-funded organizations but only nine state-funded organizations reported offering pregnancy options counseling. Respondents at state-only-funded organizations often described directing pregnant women exclusively to prenatal care. Regardless of funding source, most organizations provided women a list of agencies offering abortion, adoption and prenatal care. However, some respondents expressed concern that providing other information about abortion would threaten their state funding. In contrast, respondents indicated staff would make appointments for prenatal care, assist with Medicaid applications and, in some instances, directly connect women with adoption-related services. CONCLUSIONS: Pregnancy options counseling varied by organizations' funding guidelines. Additionally, abortion referrals were less common than referrals for other pregnancy-related care. IMPLICATIONS: Programmatic guidelines restricting information on abortion counseling and referrals may adversely affect care for pregnant women at publicly funded family planning organizations. PMID- 30287247 TI - The Clinical Significance of Cerebral Microbleeds in Infective Endocarditis Patients. AB - We assessed the clinical features of cerebral microbleeds (CMBs) and their association with clinical outcomes in active infective endocarditis patients. From January 2009 to June 2015, 132 active IE patients diagnosed per the modified Duke's criteria were retrospectively reviewed. Brain magnetic resonance imaging was performed in 102 patients, and 74 patients whose image data were available to assess CMBs were enrolled. CMBs were defined as hypointense lesion <10 mm in diameter, seen on T2* or susceptibility-weighted imaging. Forty patients had CMB and 34 did not. Patients with CMB were older, and the proportion of prior antiplatelet therapy, staphylococcal infection, and prosthetic valve endocarditis were higher than in patients without CMB. Surgery was performed in 25 (63%) patients with CMB and 24 (71%) patients without CMB. There was no significant difference in the de novo stroke incidence postoperatively (16% vs 17%, P = 0.95). Although all-cause mortality rate tended to be higher in patients with CMB, there were no significant differences in the in-hospital mortality rate and estimated 1-year major adverse event rate between the 2 groups (13% vs 12%, P = 0.92; 20% vs 19%, P = 0.35). Cox regression analysis adjusting age and operative risk did not show that CMB was a significant risk factor for all-cause death and major adverse event. Patients with CMB were older than those without, and microbleeds were associated with antiplatelet therapy, staphylococcal infection, and prosthetic valve endocarditis. However, the mid-term clinical outcomes of patients with CMB and those without were comparable. PMID- 30287248 TI - Predictive value of plasma matrix metalloproteinase-9 concentrations for spontaneous haemorrhagic transformation in patients with acute ischaemic stroke: A cohort study in Chinese patients. AB - Whether matrix metalloproteinase 9 (MMP-9) concentrations in plasma predict risk of spontaneous haemorrhagic transformation (sHT) in acute ischaemic stroke is unclear. From 1 March 2003 to 27 February 2006, patients with acute ischaemic stroke admitted to West China Hospital within 24 h of onset and healthy controls were enrolled and blood samples obtained. Plasma MMP-9 concentrations were determined using enzyme-linked immunosorbent assay, and sHT was diagnosed based on brain computed tomography or magnetic resonance performed 3-14 d after stroke onset. MMP-9 concentrations were compared for sHT patients, non-sHT patients and healthy controls. The threshold concentration for predicting sHT was determined using receiver operating characteristic analysis and the association between MMP 9 concentration and sHT was tested. One hundred and sixty-eight stroke patients and 40 healthy controls were included. Spontaneous HT occurred in 17.3% (29/168) of stroke patients and median plasma MMP-9 concentration in the sHT subgroup [244.3 ng/mL; interquartile range (IQR), 190.6-431.4] was significantly higher than in the non-sHT subgroup (110.0 ng/mL; IQR, 54.4-172.2) as well as in healthy controls (63.3 ng/mL; IQR 37.9-84.9) (both P < 0.001). We identified 181.7 ng/mL as the threshold MMP-9 concentration, for which the positive predictive value was 48% and the negative predictive value was 96%. After controlling for potential confounding factors, MMP-9 concentration >181.7 ng/mL was an independent predictor of sHT (odds ratio 18.8, 95% confidence interval 6.0-58.5, P < 0.001). Plasma MMP-9 concentration >181.7 ng/mL within 24 h after stroke onset independently predicts sHT in patients with ischaemic stroke. PMID- 30287249 TI - Hemangioblastomatosis-associated negative-pressure hydrocephalus managed with improvised shunt. AB - Low-pressure hydrocephalus (LPH) is a rare clinical diagnosis, characterized by neurologic decline and ventriculomegaly that persists despite normal to low intracranial pressure. LPH is typically managed by negative-pressure drainage via ventriculostomy, followed by low-resistance shunt insertion. We present the case of a middle-aged man with a history of hemangioblastomatosis who had spontaneous subarachnoid hemorrhage. He was treated with a ventriculoperitoneal shunt and then underwent resection of a Meckel's cave hemangioblastoma and whole brain irradiation. One month later, he presented to us with worsening symptoms and hydrocephalus despite shunt interrogations and revisions revealing no malfunction. Ventriculostomy drainage at negative-pressure was required for resolution of symptoms and ventriculomegaly, leading us to a diagnosis of LPH. This was successfully treated using an improvised ultra-low pressure valveless ventriculoperitoneal shunt, with maintained resolution of LPH for over one year. The system was created by ligating the distal slit valve end of a peritoneal catheter to prevent reflux and allow sub-zero pressure drainage by siphoning. PMID- 30287250 TI - Patterns of care and outcomes of postoperative radiation for low-grade gliomas in United States hospitals. AB - It is unclear whether there is a survival benefit with postoperative radiation for low-grade gliomas deemed to be high-risk. We sought to analyze patterns of care and outcomes of radiation use. We accessed the National Cancer Database to identify patients with WHO grade II oligodendroglioma or astrocytoma between 2010 and 2012. Multivariable logistic regression was used to identify predictors of radiation use and multivariable Cox regression was used to identify covariables associated with differences in survival. There were 1952 patients included in this study, of which 518 (26.5%) received postoperative radiation. The majority had oligodendroglioma histology (n = 1121, 57.4%) compared to astrocytoma (n = 831, 42.6%). There were 1626 patients who were either >=40 years old or underwent a subtotal resection ("high-risk"), and from these 495 (30.4%) received postoperative radiation. On multivariable logistic regression treatment at an academic facility (OR 0.72) was associated with a lower likelihood of receiving postoperative radiation. Astrocytoma histology (OR 2.08), age >=40 years (OR 2.23), tumor size >=6 cm (OR 1.64), subtotal resection (OR 1.55), and chemotherapy use (OR 3.93) were associated with an increased likelihood of postoperative radiation. On multivariable analysis, astrocytoma histology (HR 3.49, p < 0.001) and receipt of radiation (HR 2.06, p < 0.001) were associated with worse overall survival. GTR (HR 0.51, p = 0.001) was associated with improved overall survival. Patients treated in United States hospitals are not routinely referred for postoperative radiation for high-risk, low-grade gliomas. Patients who received radiation did not do better than those who did not receive radiation.

AB - Aedes aegypti is the primary vector of dengue viruses in Thailand. Control of this mosquito continues to rely heavily on use of insecticides in various forms and applications. The synergistic effect of piperonyl butoxide (PBO), combined with deltamethrin against eight populations of Ae. aegypti collected from different regions in Thailand is presented. The standard WHO adult contact bioassays found all populations with low to moderate levels of resistance to deltamethrin alone (using a 0.05% discriminating concentration), with final mortalities ranging from 15.6 to 70%, while a laboratory strain was fully susceptible (100% mortality). Pre-exposure of female mosquitoes to 4% PBO for 1 h, followed immediately by exposure to deltamethrin for 1 h, significantly increased mortality in seven populations (64.8-98.1%) with the exception of mosquitoes derived from Lampang Province. The knockdown time (KDT) synergist ratios between deltamethrin only and PBO + deltamethrin ranged from 1.7 to 2.8 for KDT50 and 1.9 to 4.0 for KDT95. Between deltamethrin alone and mosquitoes exposed to PBO + deltamethrin, all resistant populations produced significant differences (P < 0.05) in final 24-h mortality, except marginally for Lampang (P = 0.053). The synergistic effects of PBO with deltamethrin-resistant Ae. aegypti suggest a combination of this synergist with deltamethrin or other pyrethroid compounds can significantly enhance the effectiveness of these insecticides against pyrethroid-resistant Ae. aegypti found commonly in Thailand. PMID- 30287253 TI - Phyto-miRNA: A molecule with beneficial abilities for plant biotechnology. AB - The discovery of the phenomenon of gene silencing in 1990s opened new doors to biotechnology and plant breeding in order to supply food security. Food Security, as defined by FAO, it exists when all people, at all times, have economic access to safe, sufficient and nutritious food to meet their dietary needs and food preferences for a healthy and active life. Due to the need to ensure food security and also gene silencing potentials, research in this field began with astonishing speed and even it still continues. In this field, miRNA-associated gene silencing especially attracted the attention of scientists in order to decrypt the genes involved in process such as plant growth and development, metabolism, signal transduction, response against environmental stresses, nodule development in legumes and inducement male sterility. In addition, miRNA found a lot of applications in plant biotechnology like miRNA-based molecular markers and miRNA-based molecular breeding for plants improvement. Given to the growing importance of plant miRNAs (Phyto-miRNAs) in biotechnology and expansion of their applications in molecular breeding, it is necessary to review miRNA in an up-to date schema. In this study, it was presented both the necessary foundations of miRNAs and their important uses in plant sciences, such as molecular markers and metabolic engineering. As a result, we hope to expand the use of artificial miRNAs in plants engineering. PMID- 30287254 TI - Genomic alterations driving psoriasis pathogenesis. AB - Psoriasis is an immune mediated inflammatory skin disease with complex etiology involving interplay between environmental and genetic risk factors as disease initiating event. Enhanced understanding on genetic risk factors, differentially expressed genes, deregulated proteins and pathway-targeted therapeutics have established multiple axis of psoriasis pathogenesis. So far, loci in 424 genes are reported to be associated with psoriasis alongside copy number variations and epigenetic alterations. From clinical perspective, presence of specific genetic trigger(s) in individual psoriasis patient could aid in devising a personalized therapeutic strategy. Therefore, the review presents an updates on reported genomic alterations and their subsequent course of cutaneous inflammations that potentially drive to psoriasis.

PMID- 30287255 TI - Concordance of skin prick test and serum-specific IgE to locally produced component-resolved diagnostics for cockroach allergy. AB - BACKGROUND: Diagnosis of Periplaneta americana (American cockroach, ACR) allergy is commonly performed based on clinical history and skin prick test (SPT) or specific serum IgE (sIgE) measurement. The concordance of the findings with the SPT and sIgE results has never been investigated. OBJECTIVE: To compare the results of SPT with commercial ACR-extract (C-ACE) and sIgE measurement, using commercial kit and in-house enzyme-linked immunosorbent assay (ELISA) to the locally produced ACR extract (L-ACE) and native Per a 1, Per a 5, Per a 7, and Per a 9. METHODS: Sera from 66 individuals clinically diagnosed with chronic allergic rhinitis were included; 46 were positive SPT to C-ACE, and 20 were negative. Specific serum IgE levels were established by using a commercial test kit (ImmunoCap) and an in-house IgE-ELISA RESULTS: The percentage the C-ACE SPT positive cases that were positive by the ImmunoCap-sIgE was 32.6%, indicating low concordance of the 2 assays. With the in-house ELISA, Per a 9 gave the highest sensitivity (98.00%), positive predictive value (PPV; 95.74%), and negative predictive value (NPV; 94.74%) of the sIgE quantification. The correlation coefficients (R) of the L-ACE-SPT and sIgE to L-ACE, Per a 1, Per a 5, Per a 7, and Per a 9 and ImmunoCap sIgE were 0.133, 0.278, 0.419, 0.280, and 0.432, and 0.256, respectively. CONCLUSION: Skin prick test and sIgE measurement using commercial reagents have low concordance. Data of this study showed that sIgE to the native Per a 9 should be considered as an adjunct to the clinical history in diagnosis of ACR sensitization/allergy, particularly when the SPT and the nasal challenge, which is the gold standard method, cannot be performed.

In fact, compared to bright field microscopy (BFM), it allows a better identification of most U-sed particles. METHODS: The main contributions, both as original papers in medical journals and as monographs on PCM applied to U-sed examination, published in the period 1950-1982 (which was chosen because it includes the results of the most important investigations on the subject) were identified and analysed. Moreover, a brief analysis on the use of PCM in U-sed examination today was carried out. RESULTS: After the discovery of PCM by the Dutch physicist Frits Zernike in the 1930s, several contributions were published, most of which are forgotten today. All of them demonstrated the advantages of PCM over BFM in identifying the U-sed particles, especially casts, renal tubular epithelial cells, atypical urothelial cells associated with urothelial carcinoma, and erythrocytes (which for the 1st time were classified as dysmorphic - of glomerular origin - and isomorphic - of non glomerular origin). The analysis of six recent monographs on U-sed or urinalysis, written in English and with an international distribution, demonstrated that only in two of them the U-sed particles were mostly shown by PCM. CONCLUSION: Several papers and monographs, published since the early 1950s, have demonstrated the advantages of PCM over BFM for U-sed examination. In spite of this, PCM is not as widely used as it should be. PMID- 30287258 TI - Contribution of obesity as an effect regulator to an association between serum leptin and incident metabolic syndrome. AB - BACKGROUND: We investigated whether serum leptin can be a predictor for incident cases of MetS in a population-based study. METHODS: This is a prospective cohort study of 1590 adults aged between 40 and 70 years, who did not have MetS in 2005 2008 (at baseline) and 2008-2011 (follow-up). The baseline serum leptin concentrations were measured by radioimmunoassay. RESULTS: During an average of 2.8 years of follow-up, 113 men (17.1%) and 148 women (15.9%) developed MetS. In multivariable adjusted models, the odds ratio of incident MetS when comparing the lowest to the highest quartiles of leptin levels was 3.17 in men and 2.79 in women; nevertheless, the significance disappeared after adjusting for the body mass index (BMI). In subsidiary analyses by BMI, logistic regression analysis showed that subjects with the highest tertile of serum leptin level were 3.04 and 2.12 times more likely to have MetS than those with the lowest tertile in lean subjects (OR 3.04; 95% CI 1.44-6.41; p = .004 in men vs. OR 2.12; 95% CI 1.06 4.25; p = .036 in women, respectively). CONCLUSIONS: Obesity is an effect regulator, which can predict an association between increased serum leptin level and the incidence of MetS in lean subjects. PMID- 30287259 TI - An ELISA for quantifying GPIHBP1 autoantibodies and making a diagnosis of the GPIHBP1 autoantibody syndrome. AB - BACKGROUND: Autoantibodies against GPIHBP1, the endothelial cell transporter for lipoprotein lipase (LPL), cause severe hypertriglyceridemia ("GPIHBP1 autoantibody syndrome"). Affected patients have low serum GPIHBP1 and LPL levels. We report the development of a sensitive and specific ELISA, suitable for routine clinical use, to detect GPIHBP1 autoantibodies in serum and plasma. METHODS: Serum and plasma samples were added to wells of an ELISA plate that had been coated with recombinant human GPIHBP1. GPIHBP1 autoantibodies bound to GPIHBP1 were detected with an HRP-labeled antibody against human immunoglobulin. Sensitivity, specificity, and reproducibility of the ELISA was evaluated with plasma or serum samples from patients with the GPIHBP1 autoantibody syndrome. RESULTS: A solid-phase ELISA to detect and quantify GPIHBP1 autoantibodies in human plasma and serum was developed. Spiking recombinant human GPIHBP1 into the samples reduced the ability of the ELISA to detect GPIHBP1 autoantibodies. The ELISA is reproducible and sensitive; it can detect GPIHBP1 autoantibodies in samples diluted by >1000-fold. CONCLUSION: We have developed a sensitive and specific ELISA for detecting GPIHBP1 autoantibodies in human serum and plasma; this assay will make it possible to rapidly diagnose the GPIHBP1 autoantibody syndrome.

AB - Attention-deficit hyperactivity disorder (ADHD) is a common comorbidity in Duchenne muscular dystrophy (DMD). Until now, treatment with methylphenidate (MPH) has never been systematically assessed and described in this population. Our aim was to evaluate the effectiveness and safety of short acting MPH for learning problems in males with DMD and ADHD. Neuropsychological (cognition and behavior) and medical data of a sample of ten males (mean age = 8.1 years, range 6.3-9.8) with DMD and an ADHD diagnosis was retrospectively analyzed at baseline (T0; without MPH), short-term follow-up (T1; with MPH; mean interval T0-T1 = 8.3 months, range 4.3-15.6), and long-term follow-up (T2; mean interval T1-T2 = 23.1 months, range 2.6-77.7). An initial MPH dose of 5 mg/day was given on school mornings, with an increase of 2.5-5 mg/week depending on individual tolerance and treatment response, until a sufficiently effective dose was reached (range 0.2 0.6 mg/kg/day). At T1, results demonstrated an improvement in attention (i.e. concentration, impulsivity, and distractibility) in four patients. Suboptimal effects were reported in four patients, and no effects in two patients. At T2, seven patients showed considerable improvement in attention. No major side effects were reported. Overall, our data show that short acting MPH can be clinically effective for learning problems in males with DMD and ADHD, with regular cardiac follow-up, and close monitoring of side effects and neuropsychological effects. Furthermore, this underscores the importance of the use of validated cognitive and behavioral measurement tools with adequate sensitivity to objectively evaluate the effect of MPH. PMID- 30287262 TI - Rehabilitation Therapy for Nursing Home Residents at the End-of-Life. AB - OBJECTIVE: Ultrahigh therapy use has increased in SNFs without concomitant increases in residents' characteristics. It has been suggested that this trend may also have influenced the provision of high-intensity rehabilitation therapies to residents who are at the end of life (EOL). Motivated by lack of evidence, we examined therapy use and intensity among long-stay EOL residents. DESIGN: An observational study covering a time period 2012-2016. SETTING AND PARTICIPANTS: New York State nursing homes (N = 647) and their long-stay decedent residents (N = 55,691). METHODS: Data sources included Minimum Data Set assessments, vital statistics, Nursing Home Compare website, LTCfocus, and Area Health Resource File. Therapy intensity in the last month of life was the outcome measure. Individual-level covariates were used to adjust for health conditions. Facility level covariates were the key independent variables of interest. Multinomial logistic regression models with facility random effects were estimated. RESULTS: Overall, 13.6% (n = 7600) of long-stay decedent residents had some therapy in the last month of life, 0% to 45% across facilities. Of those, almost 16% had very high/ultrahigh therapy intensity (>500 minutes) prior to death. Adjusting for individual-level covariates, decedents in the for-profit facilities had 18% higher risk of low/medium therapy [relative risk ratio (RRR) = 1.182, P < .001], and more than double the risk of high/ultrahigh therapy (RRR = 2.126, P < .001), compared to those with no therapy use in the last month of life. In facilities with higher physical therapy staffing, decedents had higher risk (RRR = 16.180, P = .002) of high/ultrahigh therapy, but not of low/medium therapy intensity. The use of high/ultrahigh therapy in this population has increased over time. CONCLUSIONS AND RELEVANCE: This is a first study to empirically demonstrate that facility characteristics are associated with the provision of therapy intensity to EOL residents. Findings suggest that facilities with a for-profit mission, and with higher staffing of therapists, may be more incentivized to maximize therapy use, even among the sickest of the residents. PMID- 30287263 TI - Long-term Impact of Hip Fracture on the Use of Healthcare Resources: a Population Based Study. AB - OBJECTIVES: To assess the impact of hip fracture (HF) on health care expenditures and resource use. DESIGN: Observational, retrospective study. An administrative registry was used to obtain sociodemographic, clinical, and expenditure data of patients treated in centers all over Catalonia (North-East Spain). SETTING AND PARTICIPANTS: Male and female patients aged 65 years or older admitted to a Catalonian hospital due to hip fracture (HF) between January 1 2012, and December 31, 2016. MEASURES: The study data set included the expenditure and frequency of using nonemergency transport, rehabilitation, skilled nursing facility, specialist visits, admissions to the emergency department, hospitalization, pharmacy, and primary care. The patient status at each time point included living at home, staying in hospital, staying in a skilled nursing facility, institutionalized in a nursing home, and death. RESULTS: The record included 38,628 patients (74.4% female) with a mean [standard deviation (SD)] age of 84.9 (7.07) years. The average expenditure per patient during the first year after hospital admission was ?11,721.06, the index hospitalization being the leading expenditure (?4740.29). Expenditures related to hospitalization and skilled nursing facility remained higher than preinjury throughout the 3 years following HF. Three years after the index admission, 44.9% of patients had died, 39.7% were living in their homes, 14.2% were in a nursing home, 0.9% were in a skilled nursing facility, and 0.3% were in hospital. The expenditure of hospitalizations, primary care, and visits to the emergency department increased few months before the HF. CONCLUSIONS: In patients hospitalized for HF, the expenditure per patient decreases after hospital discharge but the use of healthcare resources is not restored to preinjury values. The increase of expenditures associated with primary care services, hospitalization, and emergency department services during the few months preceding hospital admission suggests a decline of health status in these patients. PMID- 30287265 TI - Nano-targeted relaxin impairs fibrosis and tumor growth in pancreatic cancer and improves the efficacy of gemcitabine in vivo. AB - Cancer-associated fibroblasts (CAFs), are the key effector cells in pancreatic ductal adenocarcinoma (PDAC), known to induce tumor growth and progression. Pancreatic stellate cells (PSCs) are the precursors of CAFs in PDAC that secrete abundant extracellular matrix, growth factors and cytokines. In this study, we targeted human relaxin-2 (RLX), an endogenous hormone, to PSCs to inhibit their differentiation into CAF-like myofibroblasts. RLX significantly inhibited TGF beta induced PSCs differentiation by inhibiting pSmad2 signaling pathway. In vitro in primary human PSCs (hPSCs), treatment with RLX dose-dependently inhibited the migration, contraction, and protein expression of alpha smooth muscle actin and collagen I These data demonstrate that RLX can regulate hPSCs activation in vitro. However, RLX has several drawbacks i.e. poor pharmacokinetics and systemic vasodilation, that limits its preclinical and clinical application. Thus, we designed and successfully synthesized a nanoparticle system by chemically conjugating RLX to superparamagnetic iron oxide nanoparticle (SPION) to improve its pharmacokinetics. Interestingly, we found RLX SPION to be more efficacious compared to free RLX in vitro. Significantly, we observed RLX-SPION retarded the tumor growth by itself and also potentiated the effect of gemcitabine in a subcutaneous co-injection (Panc1 and hPSCs) tumor model. The treatment resulted in significant inhibition in tumor growth, which was attributed to reduced collagen I (ECM), desmin (hPSC marker) and CD31 (endothelial marker) expression. In contrast, free RLX showed no significant effects. Altogether, this study presents a novel therapeutic approach against tumor stroma using RLX-SPION to achieve an effective treatment against pancreatic tumor. PMID- 30287264 TI - The Change in Nursing Home Residents' Preferences Over Time. AB - OBJECTIVES: Nursing home (NH) residents' preferences for everyday living are the foundation for delivering individualized person-centered care. Yet, work has not examined what the most and least important preferences of nursing home residents are and if those preferences change over time. DESIGN: This study examined the change in nursing home residents' (n = 255) preferences for everyday living over a 3-month period. Participants were recruited from 28 NHs in the suburbs of a major metropolitan East Coast area of the United States. MEASURES: Residents were interviewed face-to-face using the Preferences for Everyday Living Inventory Nursing Home version at baseline (T1) and 3 months later (T2). Change was analyzed in 2 ways: (1) percentage exact agreement (eg, respondent stated "very important" at both time points) and (2) percentage of preferences that remained either important or not important between T1 and T2. RESULTS: Sixteen preferences were rated as very or somewhat important by 90% or more of NH residents. With regard to the stability of preference ratings, findings demonstrate an average exact agreement of 59%, and an average important versus not important agreement of 82%. In addition, 68 of the 72 preferences had 70% or higher stability over time. In other words, the preference either remained "important" or "not important" to the NH resident 3 months later. Preferences in the domain of enlisting others in care had the least amount of change. CONCLUSION/IMPLICATIONS: This study highlights the most important everyday living preferences of NH residents and provides assurance to care providers that the majority of preferences assessed via the PELI are both important to NH residents and stable over time. Preference-based care plans can be designed and used over a 3-month period with confidence by providers. PMID- 30287266 TI - The application of nanotechnology in immune checkpoint blockade for cancer treatment. AB - Cancer immunotherapy, which could utilize the host's immune system to kill tumor cells, has great potential in long-term inhibition of tumor growth and recurrence compared to chemotherapy and radiotherapy. As we know, tumors exhibit powerful adaption to escape the destruction of immune system at the late stage of diseases due to overactivation of immune checkpoint pathways which function as natural "brakes" for immune responses. The newly emerging immune checkpoint inhibitors are regarded as the breakthrough for cancer immunotherapy as they can re-boost the host's immune system by restoring T cells function and promoting cytotoxic T lymphocytes (CTLs) responses. However, there is still scope for improvement in enhancing the clinical efficacy and reducing side effects of these immune modulators. In this review, we mainly introduce the basic mechanisms of the immune checkpoint pathways and outline the recent successes of immune checkpoint blockade (ICB) therapy in combination with nanoparticle delivery system. Furthermore, the underexplored potential in application of nanotechnology to enhance the efficacy of immune checkpoint therapy and overcome the limits of immune checkpoint inhibitors is also discussed. PMID- 30287267 TI - Exosomes as adjuvants for the recombinant hepatitis B antigen: First report. AB - Over the past few years, exosomes, a class of extracellular vesicles (EVs), have emerged as key players for inter-cellular communication ultimately modulating the behavior of target cells with countless outcomes. Nevertheless, the potential role of exosomes as vaccine adjuvants remains largely unexplored. Herein, we hypothesized that exosomes derived from immune cells may have an immunostimulatory effect and could constitute a good target towards the development of new fine-tuned vaccine adjuvants. To accomplish this goal, exosomes isolated from lipopolysaccharide endotoxin (LPS)-stimulated human monocytic cell line (THP-1) were characterized and tested for their non-specific immunostimulatory activity when administered subcutaneously to healthy mice; additionally, exosomes' vaccine adjuvant ability was also disclosed after their inclusion in vaccine formulations. The results obtained suggested that the isolated exosomes evoked a pro-inflammatory profile in spleen cells of healthy mice through the induction of cytokines such as tumor necrosis factor alpha (TNF alpha), chemokine (C-C motif) ligand 5 (CCL5, also known as RANTES) and interleukin 1 beta (IL-1beta). Moreover, subcutaneous vaccination of mice with exosomes combined with a solution of hepatitis B recombinant antigen (HBsAg) or combined with a suspension containing HBsAg loaded poly-epsilon-caprolactone (PCL)/chitosan nanoparticles (NPs), induced a humoral immune response quite similar to the one achieved with the experimental control group (HBsAg solution without exosomes). However, exosomes triggered an immunomodulator effect on the cellular immune response, highlighted by the enhancement of IFN-gamma secretion. To the best of authors knowledge, this is the first report describing extensively the role of unmodified exosomes as adjuvants and co-adjuvants for hepatitis B vaccination strategies. PMID- 30287269 TI - Cell cycle regulator, small silencing RNA, and segmentation patterning gene expression in relation to embryonic diapause in the band-legged ground cricket. AB - Insects enter diapause to synchronize their life cycle with biotic and abiotic conditions favorable for their development, reproduction, and survival. Adult females of the band-legged ground cricket Dianemobius nigrofasciatus (Orthoptera, Glyllidae) respond to environmental factors in autumn and lay diapause-destined eggs. The eggs arrest their development and enter diapause at a very early embryonic stage, specifically the cellular blastoderm. To elucidate the physiological mechanisms underlying this very early stage programmed developmental arrest, we investigated the cell division cycle as well as the expression of cell cycle regulators, small silencing RNAs, and segment patterning genes. The diapause embryo arrests its cell cycle predominantly at the G0/G1 phase. The proportion of cells in the S phase of the cell cycle abruptly decreased at the time of developmental arrest, but further changes of the G0/G1 and G2/M were later observed. Thus, cell cycle arrest in the diapause embryo is not an immediate event, but it takes longer to reach the steady state. We further elucidated molecular events possibly involved in diapause preparation and entry. Downregulation of Proliferating cellular antigen (PCNA; a cell cycle regulator), caudal and pumilio (cad and pum; early segmentation genes) as well as P-element induced wimpy testis (piwi) (a small silencing RNA) prior to the onset of developmental arrest was notable. The downregulation of PCNA, cad and pum continued even after entry into developmental arrest. In contrast to upregulation in non-diapause eggs, Cyclin D (another cell cycle regulator) and hunchback, Kruppel, and runt (gap and pair-rule genes) were downregulated in diapause eggs. These molecular events may contribute to embryonic diapause of D. nigrofasciatus. PMID- 30287270 TI - Chlordecone potentiates auto-immune hepatitis and promotes brain entry of MHV3 during viral hepatitis in mouse models. AB - Chlordecone is an organochlorine used in the 1970's as a pesticide in banana plantations. It has a long half-life in the soil and can potentially contaminate humans and animals through food. Chlordecone targets, and mainly accumulates in, the liver, leading to hepatomegaly and neurological signs in mammals. Chlordecone does not cause liver injuries or any inflammation by itself at low doses, but it can potentiate the hepatotoxic effects of other chemicals and drugs. We studied the impact of chlordecone on the progression of acute hepatitis in mouse models of co-exposure to chlordecone with Concanavalin A or murine hepatitis virus type 3. We examined the progression of these two types of hepatitis by measuring hepatic transaminase levels in the serum and inflammatory cells in the liver, liver histological studies. Amplified tremors presented in the MHV3- chlordecone mouse model had led us to study the expression of specific genes in the brain. We show that chlordecone amplifies the auto-immune hepatitis induced by Concanavalin A by increasing the number of liver NKT cells, which are involved in liver damage. Chlordecone also accelerated the death of mice infected by murine hepatitis virus and enhanced the entry of the virus into the cervical spinal cord in infected mice, leading to considerable neurological damage. In conclusion, chlordecone potentiates both the Concanavalin A-induced hepatitis and brain damage caused by an hepatotropic/neurotropic virus. PMID- 30287268 TI - The Anorexia Nervosa Genetics Initiative (ANGI): Overview and methods. AB - BACKGROUND: Genetic factors contribute to anorexia nervosa (AN); and the first genome-wide significant locus has been identified. We describe methods and procedures for the Anorexia Nervosa Genetics Initiative (ANGI), an international collaboration designed to rapidly recruit 13,000 individuals with AN and ancestrally matched controls. We present sample characteristics and the utility of an online eating disorder diagnostic questionnaire suitable for large-scale genetic and population research. METHODS: ANGI recruited from the United States (US), Australia/New Zealand (ANZ), Sweden (SE), and Denmark (DK). Recruitment was via national registers (SE, DK); treatment centers (US, ANZ, SE, DK); and social and traditional media (US, ANZ, SE). All cases had a lifetime AN diagnosis based on DSM-IV or ICD-10 criteria (excluding amenorrhea). Recruited controls had no lifetime history of disordered eating behaviors. To assess the positive and negative predictive validity of the online eating disorder questionnaire (ED100K v1), 109 women also completed the Structured Clinical Interview for DSM-IV (SCID), Module H. RESULTS: Blood samples and clinical information were collected from 13,363 individuals with lifetime AN and from controls. Online diagnostic phenotyping was effective and efficient; the validity of the questionnaire was acceptable. CONCLUSIONS: Our multi-pronged recruitment approach was highly effective for rapid recruitment and can be used as a model for efforts by other groups. High online presence of individuals with AN rendered the Internet/social media a remarkably effective recruitment tool in some countries. ANGI has substantially augmented Psychiatric Genomics Consortium AN sample collection. ANGI is a registered clinical trial: clinicaltrials.govNCT01916538; https://clinicaltrials.gov/ct2/show/NCT01916538?cond=Anorexia+Nervosa&draw=1&rank 3. PMID- 30287271 TI - Clinical evaluation of an MRI-to-ultrasound deformable image registration algorithm for prostate brachytherapy. AB - PURPOSE: Identifying dominant intraprostatic lesions (DILs) on transrectal ultrasound (TRUS) images during prostate high-dose-rate brachytherapy (HDR-BT) treatment planning is challenging. Multiparametric MRI (mpMRI) is the tool of choice for DIL identification; however, the geometry of the prostate on mpMRI and on the TRUS may differ significantly, requiring image registration. This study evaluates the efficacy of an in-house software for MRI-to-TRUS DIL registration (MR2US) and compares its results to rigid and B-Spline deformable registration. METHODS AND MATERIALS: Ten patients with intermediate-risk prostate cancer, each with mpMRI and TRUS data sets, were included in this study. Five radiation oncologists (ROs) with expertise in TRUS-based HDR-BT were asked to cognitively contour the DIL onto the TRUS image using mpMRI as reference. The contours were analyzed for concordance using simultaneous truth and performance level estimation algorithm. Similarity indices, DIL volumes, and distance between centroid positions were measured to compare the consensus contours against the contours from ROs and the automated algorithms; registration time between all contouring methods was recorded. RESULTS: MR2US registration had the highest dice coefficients among all patients with a mean of 0.80 +/- 0.13 in comparison to rigid (0.65 +/- 0.20) and B-Spline (0.51 +/- 0.30). The distance between centroid positions between simultaneous truth and performance level estimation contour and MR2US, rigid, and B-Spline contours were 5 +/- 2, 7 +/- 5, and 18 +/- 11 mm, respectively. The average registration time was significantly shorter for MR2US (11 +/- 2 s) and rigid algorithm (7 +/- 1 s) compared to ROs (227 +/- 27 s) and B Spline (199 +/- 38 s). CONCLUSIONS: The efficacy of integrating an MRI-delineated DIL into a TRUS-based BT workflow has been validated in this study. The MR2US software is fast and accurate enough to be used for DIL identification in prostate HDR-BT. PMID- 30287272 TI - Hemispheric mPFC asymmetry in decision making under ambiguity and risk: An fNIRS study. AB - The Iowa Gambling Task (IGT) is a commonly used task for testing decision-making under ambiguity (the early stage) and risk (the late stage). However, differences between the temporal dynamic signals underlying these two types of decision making as well as the hemispheric specificity of decision making during the IGT remain unknown. The present study sought to address this gap by focusing on the medial prefrontal cortex (mPFC), which plays an important role in decision-making across life domains. We used functional near-infrared spectroscopy (fNIRS) with high spatial and temporal resolution and measured oxy-hemoglobin concentration within the mPFC in 25 healthy participants who performed the IGT. Results showed that there are different activations of the right and left hemispheres of the mPFC during the different stages of IGT and types of decisions. This implies that the left and right mPFC can have different patterns of involvement in decision making, at least in IGT decisions, including making good (low risk) and bad (high risk) choices, under ambiguity and under risk conditions. PMID- 30287273 TI - Behavioural, metabolic and neurochemical effects of environmental enrichment in high-fat cholesterol-enriched diet-fed mice. AB - While chronic high-fat feeding has long been associated with the rising incidence of obesity/type 2 diabetes, recent evidence has established that it is also associated with deficits in hippocampus-dependent memory. In this regard, environmental enrichment (EE) is an animal housing technique composed of increased space, physical activity, and social interactions, which in turn increases sensory, cognitive, motor, and social stimulation. EE leads to improved cerebral health as defined by increased neurogenesis, enhanced learning and memory and resistance to external cerebral insults. In the present study, the impacts of environmental enrichment (EE) on Swiss mice fed a high-fat, cholesterol-enriched diet (HFECD; 20% fat and 1.5% cholesterol) were investigated. Here, we demonstrated that EE, when initiated 4 weeks after the beginning of HFECD in mice, prevents HFECD-induced spatial memory and object recognition impairment, which were tested in T-maze and object recognition tests. Although EE did not affect HFECD-induced weight gain or hypercholesterolaemia, it improved glucose tolerance. On the other hand, EE was unable to mitigate a decrease in brain-derived neurotrophic factor (BDNF) and IL-6 hippocampal levels induced by the HFECD. Overall, while our results reinforce the positive and neuroprotective effects of EE on cognition they do not support a role for EE in preventing the neurochemical changes induced by the HFECD. Based on clinical observations that nondiabetic individuals with mild forms of impaired glucose tolerance have a higher risk of cognitive impairments, one can speculate about the connection between the effects of EE on glucose intolerance and its effects on cognition. PMID- 30287274 TI - Terrestrial dispersal of invasive signal crayfish during vulnerable life stages. AB - 1. Aquatic invertebrates commonly disperse between waterbodies by flight, though some decapods can emigrate from the water and walk overland. 2. The signal crayfish (Pacifastacus leniusculus, Dana) is a highly invasive species that can survive for days to weeks out of water, though it is unclear to what extent vulnerable life stages, such as ovigerous females or juvenile crayfish, terrestrially emigrate. Understanding this behaviour is important to consider during the management of crayfish stocks, since a single ovigerous female could potentially introduce hundreds of hatchlings to a new waterbody, which could themselves disperse overland. 3. Here, in a laboratory study, we examined the terrestrial emigration tendency of juvenile crayfish and compared the terrestrial emigration behaviour and overland walking speed of ovigerous and non-ovigerous females. 4. Size had a significant influence on juvenile crayfish terrestrial emigration tendency, where only those larger than 16.6 mm (carapace length) left the water. Ovigerous and non-ovigerous female signal crayfish showed no significant difference in terrestrial emigration tendency nor overland walking speed. 5. This is the first study to directly examine the terrestrial emigration behaviour of crayfish during these different life stages. These findings highlight the importance of considering animal behaviour during management strategies. PMID- 30287276 TI - A case of small bowel obstruction due to infection with Bolbosoma sp. (Acanthocephala: Polymorphidae). AB - A case of small bowel obstruction caused by Bolbosoma sp. infection is reported. A 27-year-old woman admitted with abdominal pain was diagnosed as small bowel obstruction. Laparoscopic surgery revealed induration in jejunum at ca. 120 cm distal to the ligament of Treiz, attributed to a band connecting the serosa to the ascending mesocolon. Resected band contained an acanthocephalan accompanying foreign body reaction with abscess formation. The parasite belonged to the genus Bolbosoma, of which identification was made by DNA sequence analysis. This is the eighth case of Bolbosoma infection in humans, and the first one causing an ileus. PMID- 30287275 TI - Cardiometabolic assessment of lamin A/C gene mutation carriers: A phenotype genotype correlation. AB - AIMS: Mutations of the LMNA gene encoding lamin A/C induce heterogeneous phenotypes ranging from cardiopathies and myopathies to lipodystrophies. The aim of this study was to compare cardiometabolic complications in patients with heterozygous LMNA mutations at the 482nd codon, the 'hotspot' for partial lipodystrophy, with carriers of other, non-R482 LMNA mutations. METHODS AND RESULTS: This study included 29 patients with R482 LMNA mutations, 29 carriers of non-R482 LMNA mutation and 19 control subjects. Cardiac and metabolic phenotypes were compared between groups. A family history of either cardiac implantable electronic devices (CIEDs; P < 0.001) or sudden death (P < 0.01) was more frequent in non-R482 than R482 carriers. The non-R482 carriers also had more abnormalities on electrocardiography and received CIEDs more often than R482 carriers (P < 0.001). On cardiac ultrasound, non-R482 patients had greater frequencies of left atrial enlargement (P < 0.05) and lower left ventricular ejection fractions (P < 0.01) than R482 carriers. In contrast, R482 carriers had lower BMI (P < 0.05), leptin (P < 0.01) and fat mass (P < 0.001), but higher intra-/total abdominal fat-mass ratios (P < 0.001) and prevalences of diabetes (P < 0.01) and hypertriglyceridaemia (P < 0.05) than non-R482 carriers, with a trend towards more coronary artery disease. However, non-R482 carriers had higher intra /total abdominal fat-mass ratios (P < 0.02) and prevalences of diabetes (P < 0.001) and hypertriglyceridaemia (P < 0.05) than the controls. CONCLUSION: Non R482 carriers present more frequently with arrhythmias than R482 carriers, who twice as often have diabetes, suggesting that follow-up for laminopathies could be adjusted for genotype. Non-R482 mutations require ultra-specialized cardiac follow-up, and coronary artery disease should not be overlooked. Although overlapping phenotypes are found, LMNA mutations essentially lead to tissue specific diseases, favouring genotype-specific pathophysiological mechanisms. PMID- 30287277 TI - What Do the Guidelines Say for Metastatic Prostate Cancer Starting Androgen Deprivation Therapy? National Comprehensive Cancer Network, European Society for Medical Oncology, and European Association of Urology recommendations. AB - Clinical trial data forms the foundation of how we treat men with metastatic prostate cancer who are initiating therapy. However, clinical trial data does not answer everything; hence, good clinical practice, pragmatism, and occasionally extrapolation drives how we manage these patients. Fortunately, multiple international guideline committees meet regularly and offer clinical guidance. In this mini-review, we focus on the United States National Comprehensive Cancer Network, European Society for Medical Oncology, and European Association of Urology (EAU) recommendations for the initial treatment of metastatic prostate cancer. PMID- 30287278 TI - Ribosomal RACK1 promotes proliferation of neuroblastoma cells independently of global translation upregulation. AB - Neuroblastoma is the most frequent solid tumor among those diagnosed during infancy and like most tumors, it is characterized by elevated rates of cell proliferation, migration and invasion. RACK1 is among the top 10 genes identified for unfavorable prognosis at 5 years in neuroblastoma cases and its depletion negatively affects proliferation, invasion and migration. Here, we show that the ribosomal localization of RACK1 modulates the proliferation of SH-SY5Y neuroblastoma cells by regulating the expression of cell cycle genes, such as Cyclin D1, D3 and B1 independently of global translation increase. Ribosomal RACK1 is not involved in general protein synthesis, which is instead dependent on total RACK1 and PKC but independent from mTOR. Thus, ribosomal RACK1 may represent a new target to develop more efficient therapies for neuroblastoma treatment.

AB - Bone marrow mesenchymal stem/stromal cells (MSCs) maintain bone homeostasis and repair through the ability to expand in response to mitotic stimuli and differentiate into skeletal lineages. Signalling mechanisms that enable precise control of MSC function remain unclear. Here we report that by initially examining differences in signalling pathway expression profiles of individual MSC clones, we identified a previously unrecognised signalling mechanism regulated by epidermal growth factor (EGF) in primary human MSCs. We demonstrate that EGF is able to activate beta-catenin, a key component of the canonical Wnt signalling pathway. EGF is able to induce nuclear translocation of beta-catenin in human MSCs but does not drive expression of Wnt target genes or T cell factor (TCF) activity in MSC reporter cell lines. Using an efficient Design of Experiments (DoE) statistical analysis, with different combinations and concentrations of EGF and Wnt ligands, we were able to confirm that EGF does not influence the Wnt/beta catenin pathway in MSCs. We show that the effects of EGF on MSCs are temporally regulated to initiate early "classical" EGF signalling mechanisms (e.g via mitogen activated protein kinase) with delayed activation of beta-catenin. By RNA sequencing, we identified gene sets that were exclusively regulated by the EGF/beta-catenin pathway, which were distinct from classical EGF-regulated genes. However, subsets of classical EGF gene targets were significantly influenced by EGF/beta-catenin activation. These signalling pathways cooperate to enable EGF mediated proliferation of MSCs by alleviating the suppression of cell cycle pathways induced by classical EGF signalling. PMID- 30287280 TI - Development of photosynthetic sutures for the local delivery of oxygen and recombinant growth factors in wounds. AB - Surgical sutures represent the gold standard for wound closure, however, their main purpose is still limited to a mechanical function rather than playing a bioactive role. Since oxygen and pro-regenerative growth factors have been broadly described as key players for the healing process, in this study we evaluated the feasibility of generating photosynthetic sutures that, in addition to mechanical fixation, could locally and stably release oxygen and recombinant human growth factors (VEGF, PDGF-BB, or SDF-1alpha) at the wound site. Here, photosynthetic genetically modified microalgae were seeded in commercially available sutures and their distribution and proliferation capacity was evaluated. Additionally, the mechanical properties of seeded sutures were compared to unseeded controls that showed no significant differences. Oxygen production, as well as recombinant growth factor release was quantified in vitro over time, and confirmed that photosynthetic sutures are indeed a feasible approach for the local delivery of bioactive molecules. Finally, photosynthetic sutures were tested in order to evaluate their resistance to mechanical stress and freezing. Significant stability was observed in both conditions, and the feasibility of their use in the clinical practice was therefore confirmed. Our results suggest that photosynthetic gene therapy could be used to produce a new generation of bioactive sutures with improved healing capacities. STATEMENT OF SIGNIFICANCE: Disruption of the vascular network is intrinsic to trauma and surgery, and consequently, wound healing is characterized by diminished levels of blood perfusion. Among all the blood components, oxygen and pro-regenerative growth factors have been broadly described as key players for the healing process. Therefore, in this study we evaluated the feasibility of generating photosynthetic sutures that, in addition to mechanical fixation, could locally and stably release oxygen and recombinant human growth factors at the wound site. This novel concept has never been explored before for this type of material and represents the first attempt to create a new generation of bioactive sutures with improved regenerative capabilities. PMID- 30287281 TI - Bispecific applications of non-immunoglobulin scaffold binders. AB - Non-immunoglobulin scaffolds represent a proven group of small affinity proteins that can be engineered in vitro to similar affinity and potency as monoclonal antibodies. Several novel candidate biotherapeutics that exploit the potential advantages scaffold proteins hold over larger and more complex antibodies have been developed over the past decade. The ease of using small and robust binding proteins as flexible and modular building blocks has led to the development of a wide range of innovative approaches to combine them in various bi- and multispecific formats. This progress is expected to aid the ongoing challenge of identifying niche applications where clear differentiation from antibody-based molecules will be key to success. Given the many engineering options that are available for non-immunoglobulin scaffold proteins, they have potential to not only complement but probably also surpass antibodies in certain applications. PMID- 30287282 TI - Role of Toll-like receptor 4/oxidant-coupled activation in regulating the biosynthesis of omega-3 polyunsaturated fatty acid derivative resolvin D1 in primary murine peritoneal macrophage. AB - We have previously shown that reactive oxygen species (ROS) as prooxidants can activate Toll-like receptor 4 (TLR4) with the potential to initiate, propagate and maintain "sterile" inflammation of innate immunity, which plays a mediatory role in a host of human disease states. We now present new evidence that ROS can also activate TLR4 to counter the inflammatory phenotype by increasing the production of resolvin D1 (RvD1), which is a specialized anti-inflammatory and pro-resolving lipid mediator. We used primary murine peritoneal macrophages (pM) derived from both TLR4-WT and TLR4-KO mice as a cellular model. We used potassium peroxychromate (PPC) as a direct in vitro source of exogenous ROS. PPC treatment increased intracellular ROS levels, which decreased intracellular total antioxidant capacity, thus suggesting an enhanced cellular oxidative stress. PPC and LPS-EK (a TLR4-specific agonist) increased pro-inflammatory TNFalpha production with noeffect on IL-10, an anti-inflammatory cytokine. Treatment with the prooxidant increased the expression of 12 lipoxygenase (12-LOX) and 5 lipoxygenase (5-LOX) only in pM derived from TLR4 WT but not in pM from TLR4-KO mice. 5-LOX and 12-LOX are the key enzymes in the RvD1 biosynthetic pathway. In addition, PPC increased the expression of RvD1 receptor, a member of G-protein coupled receptor only in pM from TLR4-WT mice. Our data support the involvement of TLR4-mediated oxidant-induced pro-inflammatory phenotypes that are in opposition to the production of anti-inflammatory/pro-resolution phenotypes in macrophages. Now, we show that through TLR4 activation, exogenous oxidants can play a role both in producing proinflammatory phenotypes at the same time that it enhances resolution of inflammation to maintain a state of cellular homeostasis and prevent tissue damage/disease. PMID- 30287283 TI - Models and methods for conditioning the ischemic brain. AB - BACKGROUND: In the last decades the need to find new neuroprotective targets has addressed the researchers to investigate the endogenous molecular mechanisms that brain activates when exposed to a conditioning stimulus. Indeed, conditioning is an adaptive biological process activated by those interventions able to confer resistance to a deleterious brain event through the exposure to a sub-threshold insult. Specifically, preconditioning and postconditioning are realized when the conditioning stimulus is applied before or after, respectively, the harmul ischemia. AIMS AND RESULTS: The present review will describe the most common methods to induce brain conditioning, with particular regards to surgical, physical exercise, temperature-induced and pharmacological approaches. It has been well recognized that when the subliminal stimulus is delivered after the ischemic insult, the achieved neuroprotection is comparable to that observed in models of ischemic preconditioning. In addition, subjecting the brain to both preconditioning as well as postconditioning did not cause greater protection than each treatment alone. CONCLUSIONS: The last decades have provided fascinating insights into the mechanisms and potential application of strategies to induce brain conditioning. Since the identification of intrinsic cell-survival pathways should provide more direct opportunities for translational neuroprotection trials, an accurate examination of the different models of preconditioning and postconditioning is mandatory before starting any new project. PMID- 30287284 TI - Kindlin-2 interacts with and stabilizes DNMT1 to promote breast cancer development. AB - Integrin-interacting protein Kindlin-2, as a focal adhesion protein, promotes growth and progression of breast cancer. However, the precise mechanism that underlie the role of Kindlin-2 in breast cancer is elusive. Here, we report that the expression of Kindlin-2 positively correlated with DNA methyltransferase 1(DNMT1) in breast cancer patients. Further, we found that DNMT1 was upregulated in mammary gland tissues of mammary specific Kindlin-2 transgenic mice. More importantly, high expression of DNMT1 was observed in mammary tumors formed by Kindlin-2 transgenic mice. On the basis of these observations, DNMT inhibitor 5 aza-CdR was used and found its treatment strongly decreased Kindlin-2-induced breast cancer cell proliferation and migration. Mechanistically, Kindlin-2 increased the stability of DNA methyltransferase DNMT1 through interaction with DNMT1 and methylated CpG islands in the E-cadherin promoter. Kindlin-2 increased the occupancy of DNMT1 at E-cadherin promoter, thereby suppressing E-cadherin expression. Taken together, our data reveal that Kindlin-2 promotes breast cancer development by enhancing the stability of DNMT1. PMID- 30287285 TI - PAR2 Pepducin-Based Suppression of Inflammation and Itch in Atopic Dermatitis Models. AB - PAR2 has been proposed to contribute to lesion formation and intense itch in atopic dermatitis. Here, we tested the ability of a cell-penetrating pepducin, PZ 235, to mitigate the potentially deleterious effects of PAR2 in models of atopic dermatitis. PZ-235 significantly inhibited PAR2-mediated expression of inflammatory factors NF-kappaB, TSLP, TNF-alpha, and differentiation marker K10 by 94%-98% (P < 0.001) in human keratinocytes and suppressed IL-4 and IL-13 by 68%-83% (P < 0.05) in mast cells. In delayed pepducin treatment models of oxazolone- and DNFB-induced dermatitis, PZ-235 significantly attenuated skin thickening by 43%-100% (P < 0.01) and leukocyte crusting by 57% (P < 0.05), and it inhibited ex vivo chemotaxis of leukocytes toward PAR2 agonists. Daily PZ-235 treatment of filaggrin-deficient mice exposed to dust mite allergens for 8 weeks significantly suppressed total leukocyte and T-cell infiltration by 50%-68%; epidermal thickness by 60%-77%; and skin thickening, scaling, excoriation, and total lesion severity score by 46%-56%. PZ-235 significantly reduced itching caused by wasp venom peptide degranulation of mast cells in mice by 51% (P < 0.05), which was comparable to the protective effects conferred by PAR2 deficiency. Taken together, these results suggest that a PAR2 pepducin may confer broad therapeutic benefits as a disease-modifying treatment for atopic dermatitis and itch. PMID- 30287286 TI - Endovascular Treatment of a Late False Aneurysm Complicating Open Suprarenal Mycotic Aneurysm Repair with a Cryopreserved Aortic Homograft. AB - We report a patient who was initially treated for a suprarenal mycotic aortic aneurysm. The aneurysm repair was performed using a cryopreserved arterial homograft and debranching of visceral arteries. Five years later, the patient was referred due to a large symptomatic false aneurysm at the distal homograft anastomosis. Endovascular repair was indicated and performed using a bifurcated Medtronic composite stent graft. The procedure was uneventful, while control angiography showed complete exclusion of the false aneurysm. Within 6 months of follow-up, the endograft showed favorable position and maintained patency with no signs of endoleaks. We discuss the role of the cryopreserved homografts for in situ repair of mycotic aortic aneurysms and comment on possible late complications after placing those grafts. PMID- 30287287 TI - Aortic Surgery Outcomes of Marfan Syndrome and Ehlers-Danlos Syndrome Patients at Teaching and Nonteaching Hospitals. AB - BACKGROUND: Despite improvements in prevention and management, aortic aneurysm repair remains a high-risk operation for patients with Marfan syndrome (MFS) and Ehlers-Danlos syndrome (EDS). The goal of this study was to examine differences in characteristics and outcomes of patients with MFS or EDS undergoing aortic aneurysm repair at teaching versus nonteaching hospitals. METHODS: We used the National Inpatient Sample to study patients with MFS or EDS undergoing open or endovascular aortic aneurysm repair from 2000 to 2014. RESULTS: Of 3487 patients (MFS = 3375, EDS = 112), 2974 (85%) had repair at a teaching hospital. Patients who underwent repair at a teaching hospital were slightly younger than those who underwent repair at a nonteaching hospital (38 vs. 43 years, P < 0.01) but otherwise were similar in gender (29% vs. 28% female), race (70% vs. 78% white), and connective tissue disorder diagnosis (97% vs. 97% MFS, all P >= 0.1). There were no differences in anatomy (17% vs. 19% abdominal, 67% vs. 66% thoracic, and 15% vs. 15% thoracoabdominal, all P >= 0.1) or type of repair (5% vs. 5% endovascular), but patients at nonteaching hospitals were more likely to have a dissection (49% vs. 38%, P = 0.02). There was no difference in perioperative mortality (4% vs. 6%, P = 0.5) or length of stay (median 8 days vs. 7 days, P = 0.3) between teaching and nonteaching hospitals. There was also no difference in hemorrhagic (47% vs. 43%), pulmonary (9% vs. 16%), renal (12% vs. 14%), or neurologic (5% vs. 6%) complications between teaching and nonteaching hospitals, respectively (all P >= 0.05). In analysis stratified by anatomic extent of repair, there was a lower prevalence of pulmonary complications in thoracic aorta repairs at teaching hospitals (8.1% vs. 18.4%, P = 0.01) but a higher prevalence of hemorrhage in abdominal aortic repairs at teaching hospitals (45.6% vs. 20.6%, P = 0.04) as compared with nonteaching hospitals. CONCLUSIONS: Patients with MFS and EDS who undergo aortic aneurysm repair have their operations predominantly at teaching hospitals, but those patients who undergo repair at nonteaching hospitals do not have worse mortality or morbidity despite a higher incidence of dissection. PMID- 30287288 TI - Objective Performance Goals for Surgical Treatment of Critical Limb Ischemia. AB - BACKGROUND: Based on prospective vein bypass trials for lower leg ischemia, objective performance goals (OPG) were established by the Society for Vascular Surgery (SVS) and are used as a benchmark tool for open and endovascular treatments. This study aims to analyze OPG of all patients with critical limb ischemia (CLI) treated by open revascularization techniques at a tertiary care facility in routine practice. METHODS: From January 2005 to March 2013, 315 patients (mean age 72 years) with CLI were retrospectively included in this study. Inclusion criteria were patients with Fontaine stage III and IV, realized revascularization with open surgical procedures (bypass grafting or endarterectomy), or hybrid method (open + endovascular). Exclusion criteria were primary major amputations, patients with revascularization treatments of the index leg within the last 3 months, and missing aftercare. Primary end point was "amputation-free survival" (AFS), and secondary end point was "freedom from major adverse limb event + perioperative death (30 days)" (MALE + POD) according to the SVS. The technical end point was primary patency. Mean follow-up was 34 months. The following variables were studied: clinical stage (Fontaine), previous interventions, bypass material used, and site of the distal anastomosis. The statistical evaluation and preparation was carried out using the Kaplan-Meier estimator and the log-rank test. A multivariate analysis was performed using the Cox proportional hazards model. A P value <=0.05 was considered to be statistically significant. RESULTS: A total of 128 patients (31%) fulfilling the adjusted SVS OPG criteria showed significantly better results for AFS, MALE + POD, and primary patency (P = 0.013, P = 0.015, P = 0.002, respectively). Regarding the AFS (1 year: 74%), multivariate analysis displayed significant worse results for patients with end-stage renal disease (hazard ratio [HR] 2.90, 95% confidence interval [CI] 1.83-4.60, P < 0.001) and Fontaine stage IV (HR 1.69, 95% CI 1.11-2.57, P = 0.015). Regarding MALE + POD (1 year: 64%), male patients (HR 0.64, 95% CI 0.46-0.90, P = 0.011) showed a significantly better outcome and patients without previous interventions of the index leg (HR 1.51, 95% CI 1.09-2.09, P = 0.013) showed a significantly worse outcome. CONCLUSIONS: In this study, we were able to show that it is possible to reach the efficacy of OPGs set by SVS in a surgically treated all-comers cohort of CLI patients. Nevertheless, patients who did not fulfill the SVS OPG criteria showed significantly worse results for AFS and MALE + POD. PMID- 30287289 TI - Intraluminal Thrombus Deposition Is Reduced in Ruptured Compared to Diameter matched Intact Abdominal Aortic Aneurysms. AB - BACKGROUND: The aim of this study is to compare the pattern of intraluminal thrombus (ILT) deposition in diameter-matched ruptured and nonruptured abdominal aortic aneurysms (AAAs). METHODS: We performed a single-center, retrospective study. Ruptured AAAs were collected during 24 months. Diameter-matched intact lesions were randomly selected in a 2:1 ratio and served as controls. ILT cross sectional area, relative area, maximum thickness, and asymmetric distribution were recorded at the site of maximum aneurysm size and compared between groups. Moreover, additional comparisons were performed inside the group of ruptured AAAs, between the site of maximum size and the site of rupture. RESULTS: Fifteen ruptured cases were compared with 30 nonruptured cases. ILT relative area (37.5% vs. 73.5%, P = 0.004) and maximum thickness (14.5 vs. 28 mm, P= 0.0017) were significantly reduced among ruptured compared to intact AAAs. The latter group presented mostly an anterior eccentric ILT deposition, while the former presented a more symmetrical pattern. The site of rupture was located at the site of maximum size in only 2 cases. In general, ILT was reduced at the site of rupture compared to the site of maximum aneurysm size in ruptured cases but differences did not reach statistical significance. CONCLUSIONS: In similar sized AAAs, ILT is reduced in ruptured compared to nonruptured cases. PMID- 30287290 TI - Endovascular Management of a Distally Migrated Bifurcated Endograft with a New Bifurcated Endograft. AB - A 75-year-old man presented with abdominal and lumbar pain 6 years after previous endovascular repair of an abdominal aortic aneurysm. At the time of the initial operation, the aneurysm measured 6.0 cm in maximum diameter and a bifurcated Anaconda (Vascutek) endograft had been implanted. This time, computed tomography showed a distally migrated endograft which had been folded within the sac and the aneurysm measured 8.4 cm in maximum diameter. We opted to treat this by endovascular means deploying a new bifurcated endograft with suprarenal fixation within the old one. We consider the different management options and discuss the associated technical difficulties. PMID- 30287291 TI - Percutaneous Access of an Expanding Internal Iliac Artery Aneurysm via a Direct Posterior Transgluteal Approach. AB - BACKGROUND: Internal iliac artery aneurysms (IIAAs) are rare, comprising 0.3% of all aortoiliac aneurysms. Endovascular management is associated with lower morbidity and mortality than open repair. We present a 91-year-old female with a rapidly expanding 8.2-cm IIAA who previously underwent incomplete endovascular treatment, using endovascular aneurysm repair, to exclude the right internal iliac artery (IIA). Transarterial access to the IIAA was not possible secondary to the iliac limb of the endograft over the origin of the IIA. We recommended that the patient undergo embolization and coiling of the IIAA via a direct percutaneous transgluteal approach. METHODS: With the patient in a prone position, under fluoroscopic guidance, a 10-cm long, 18-gauge needle was placed through the gluteus muscle into the right IIAA. Needle location was confirmed by angiography and a 6-French sheath was advanced into the aneurysm. Selective catheterization of the native aorta was accomplished around the occluded limb of the previously placed endograft. Aortography confirmed robust filling of 2 large lumbar arteries with brisk runoff through branches of the IIA. Coil embolization was used to treat both the lumbar arteries causing aortic endoleak, as well as the outflow branches of the IIAA. RESULTS: Completion angiography revealed static flow in the aorta and aneurysm, with minimal flow through the inflow and outflow tracts. At a 1-month follow-up appointment, repeat computed tomography angiography revealed resolution of the endoleak and no blood flow within the aneurysm. There have only been a few case reports utilizing alternative access to an IIAA. Although computed tomography and ultrasound-guided techniques have been described in the literature, a percutaneous, fluoroscopy-guided, transgluteal approach to access the IIAA is a new and unique approach. CONCLUSIONS: In patients who are not candidates for open or standard endovascular repair with a large, inaccessible IIAA, a transgluteal approach to directly access the aneurysm sac may offer a less invasive and successful management strategy. PMID- 30287292 TI - Twelve-year Follow-up Post-Thoracic Endovascular Repair in Type B Aortic Dissection Shown by Three-dimensional Printing. AB - BACKGROUND: Thoracic endovascular repair (TEVAR) is currently considered the therapy of choice for complicated type B acute aortic dissection (TBAAD). Although several papers have reported good outcomes at short- and medium-term follow-up, some questions still remain regarding the long-term durability and re intervention rate during follow-up. METHODS: We describe a case of a patient originally treated with TEVAR for TBAAD complicated by impending aortic rupture. RESULTS: Endovascular repair successfully excluded the flow through the primary entry tear but during the 12-year follow-up period the patient experienced several complications and re-interventions. Various full-size three-dimensional (3D) models of the patient-specific vasculature were printed to better explain the different interventional interventions over the 12 years of follow-up and as a hands-on tool for medical education. CONCLUSIONS: The present case report, involving long-term follow-up, provides an example of the effectiveness and the safety of TEVAR for the treatment of complicated TBAAD shown at short and medium term follow-up. However, the long-term complications that were observed in this patient during follow-up support the importance of lifelong CTA surveillance. Furthermore, this study confirms the capability of 3D printing technology as a powerful tool to support communication with patients and residents' education through the physical analysis of the real cases. PMID- 30287293 TI - Iliac Aneurysms Treated with Endovascular Iliac Branch Device: A Systematic Review and Meta-analysis. AB - BACKGROUND: Iliac branch devices (IBDs) have been increasingly reported for treating aortoiliac aneurysms. However, there are still concerns regarding this device. The aim of this study was to evaluate the safety and outcomes of IBDs in treating aortoiliac aneurysms by performing a systematic review and meta analysis. METHODS: The Medline, EMBASE, and Cochrane databases were systematically searched to identify studies on the management of aortoiliac aneurysms using IBDs. Studies were reviewed and selected using defined criteria by 2 independent investigators who abstracted data on the study characteristics, study quality, and outcomes. The extracted data were presented as a rate and converted through arcsine transformations. Individual studies were evaluated and analyzed for 7 outcomes, including technical success rate, 30-day mortality, 30 day patency, follow-up patency, endoleak rate, buttock claudication, and IBD associated reintervention. The heterogeneity of the studies was determined using the chi-squared distribution-based Q test and quantified by I2 statistics. Meta analyses were performed using both a random effects model and fixed effects model. RESULTS: Twenty-two studies with a total of 1064 patients met the inclusion criteria and were selected for analysis. The pooled technical success rate of IBD was 93% (95% confidence interval [CI]: 91-95%). After patients were treated with the IBD, the 30-day mortality rate was 2% (95% CI, 1-4%), 30-day patency rate was 93% (95% CI, 91-94%), follow-up patency was 86% (95% CI, 84 88%), endoleak rate was 12% (95% CI, 8-17%), buttock claudication rate was 6% (95% CI, 5-8%), and IBD-associated reintervention rate was 11% (95% CI, 8-14%). CONCLUSIONS: Our study demonstrates that treating aortoiliac aneurysm with IBD produces satisfactory outcomes in midterm follow-up. PMID- 30287294 TI - Endovascular Stent-graft Repair of Combined Renal Artery Aneurysm and Arteriovenous Fistula. AB - Renal artery aneurysm with concomitant presence of arteriovenous fistula is an extremely rare entity. Few reports have been described in the literature. Nowadays, endovascular repair with covered stents or transarterial embolization with coils or glue has become the first line of treatment. We present the successful repair of a distal renal artery aneurysm combined with arteriovenous fistula with stent graft. PMID- 30287295 TI - Risk Factor Analyses of Abdominal Aortic Aneurysms Growth in Japanese Patients. AB - BACKGROUND: This study aimed to retrospectively demonstrate the growth rate (mm/year) of abdominal aortic aneurysm (AAA) diameters (ADs) and to analyze risk factors for AAA expansion. METHODS: We retrospectively investigated the clinical data of 319 patients with AAAs who were followed up as outpatients for >2 years after their initial visit and who underwent computed tomography >4 times. RESULTS: The mean follow-up period was 3.7 +/- 1.5 years. The annual average growth rates according to varying ADs were as follows: 1.9 +/- 0.8 (AD 30-34 mm), 2.6 +/- 1.2 (AD 35-39 mm), 2.8 +/- 1.1 (AD 40-44 mm), 3.1 +/- 1.3 (AD 45-49 mm), 3.4 +/- 1.6 (AD 50-54 mm), and 3.5 +/- 1.4 mm (AD >=55 mm). Factors associated with AAA expansion were smoking (P = 0.017), hypertension (P < 0.001), and ADs (P < 0.001). In the subgroup analysis, data regarding growth rates of >=3 mm were extracted, and a statistically significant difference between smoking status and ADs of >=40 mm was observed. CONCLUSIONS: Factors associated with AAA expansion in Japanese patients included smoking, hypertension, and ADs, and a statistically significant difference was observed between smoking status and ADs of >=40 mm. PMID- 30287296 TI - Retrograde Use of Gore Hybrid Vascular Graft for a Complex Carotid Tandem Lesion. AB - BACKGROUND: Successful treatment of tandem lesions of carotid arteries may represent a challenging goal for the vascular specialist. In the "endovascular era," a hybrid approach may represent a viable option. CASE REPORT: We describe the case of a 65-year-old patient with severe postcarotid endarterectomy recurrent stenosis of the internal carotid artery (ICA) associated with primitive stenosis of the proximal common carotid artery (CCA) treated with retrograde stenting and carotid bypass using the Gore Hybrid Vascular Graft (GHVG). CONCLUSIONS: We demonstrated the effectiveness of the hybrid technique using GHVG in treating carotid tandem lesions involving CCA and ICA. PMID- 30287297 TI - Duplex-guided versus Conventional Percutaneous Transluminal Angioplasty of Iliac TASC II A and B Lesion: A Randomized Controlled Trial. AB - BACKGROUND: Percutaneous transluminal angioplasty (PTA) requires the use of nephrotoxic contrast. Patients with chronic kidney disease are more prone to develop contrast-induced nephropathy after utilization of contrast. Doppler ultrasound (duplex)-guided PTA (DuPTA) is a novel technique and has recently proven to be a successful alternative to conventional PTA in the treatment of iliac stenotic disease, without the use of contrast. In this randomized controlled trial, we evaluated whether DuPTA is as effective as conventional PTA in the treatment of iliac arterial stenotic disease. METHODS: From June 2013 till January 2017, 142 patients with symptomatic peripheral arterial disease (PAD), with significant (>70%) iliac stenotic lesions (both isolated and patients with multilevel disease without treatment of other lesions), were randomized to receive either conventional PTA or DuPTA of the iliac lesion, regardless of renal function. All patients received an ankle-brachial index, arterial mapping with duplex, and magnetic resonance angiography in the pre-operative work-up. Primary end point was procedural success, defined as passing the guidewire through the stenotic lesion and performing a PTA, with or without stenting. Reduction in peak systolic velocity (PSV) of >=50% after successful PTA was required in the DuPTA group. Angiographic reduction of more than 50% was required in the interventional group. Decrease in PSV was evaluated in both groups 4 weeks post-procedure. RESULTS: Passing of the guidewire through the stenotic lesion was achieved in 96.5% of the DuPTA group and 98.8% of the PTA group (P = 0.34). Although PSV decreased significantly in both groups 4 weeks post-operative, PSV reduction >=50% was significantly higher in the DuPTA group, respectively 78% vs. 58% in the PTA group (P < 0.01). The utilization of stents was significantly greater in the DuPTA group (52% vs. 18%, P < 0.01). After correction of potential confounders, significant difference in >=50% PSV reduction remained; technical success did not differ significantly. CONCLUSIONS: DuPTA is a feasible alternative to conventional PTA in the treatment of PAD on the iliac anatomic level. Duplex examination before removal of the guidewire is recommended to evaluate adequate decrease in PSV and identify potential recoil. PMID- 30287298 TI - External Iliac Artery Endofibrosis in a Female Cyclist: A Case Report. AB - External iliac artery endofibrosis is a rare disease described mainly in male endurance athletes. It presents as claudication of the lower limb during near maximum effort. The patients lack the usual risk factors for atherosclerosis, which makes diagnosis challenging. We present a case of external iliac artery endofibrosis in a female competitive cyclist. The initial surgical management was complicated by early recurrence due to intimal hyperplasia. After secondary drug eluting balloon angioplasty, the patient was able to resume competition. As such, it is important to maintain a high index of suspicion when evaluating a patient presenting with claudication symptoms in this setting. Primary treatment is surgical, and in cases of early recurrence angioplasty may be indicated. Most patients can return to full activity after healing is complete. PMID- 30287299 TI - A dynamic system of brain networks revealed by fast transient EEG fluctuations and their fMRI correlates. AB - Resting state brain activity has become a significant area of investigation in human neuroimaging. An important approach for understanding the dynamics of neuronal activity in the resting state is to use complementary imaging modalities. Electrophysiological recordings can access fast temporal dynamics, while functional magnetic resonance imaging (fMRI) studies reveal detailed spatial patterns. However, the relationship between these two measures is not fully established. In this study, we used simultaneously recorded electroencephalography (EEG) and fMRI, along with Hidden Markov Modelling, to investigate how network dynamics at fast sub-second time-scales, accessible with EEG, link to the slower time-scales and higher spatial detail of fMRI. We found that the fMRI correlates of fast transient EEG dynamic networks show highly reproducible spatial patterns, and that their spatial organization exhibits strong similarity with traditional fMRI resting state networks maps. This further demonstrates the potential of electrophysiology as a tool for understanding the fast network dynamics that underlie fMRI resting state networks. PMID- 30287300 TI - Training emotion regulation through real-time fMRI neurofeedback of amygdala activity. AB - Being in control of one's emotions is not only desirable in many everyday situations but is also a great challenge in a variety of mental disorders. Successful intentional emotion regulation is related to down-regulation of amygdala activity. Training mental interventions supported by neurofeedback of one's own amygdala activity using real-time (rt-)fMRI might be beneficial for mental health and well-being. Rt-fMRI guided amygdala-downregulation using cognitive interventions such as a "reality check", however, have not been well investigated. Fifteen healthy subjects underwent four rt-fMRI sessions with neurofeedback of their own amygdala activity while applying a reality check as an emotion regulation strategy in order to down-regulate their amygdala signal during a stimulation with emotional pictures. The Control group comprised of eleven subjects also trained emotion regulation but without obtaining feedback. We hypothesized more prominent down-regulation of amygdala activity at the end of the training in the Feedback group. We investigated effects over time and between groups and further task specific connectivity of the amygdala by using psychophysiological interaction analyses. Four weekly amygdala-based feedback sessions resulted in significantly decreased amygdala activity (p = 0.003, d = 0.93), also compared to the Control group (p = 0.014, d = 1.12). Task specific connectivity of the amygdala with the anterior cingulate cortex, hippocampus and distinct prefrontal areas was increased in the Feedback group. Training of emotion regulation supported by rt-fMRI neurofeedback resulted in a prominent amygdala down-regulation compared to training without feedback. The finding implicates successful emotion regulation, compliant with emotion control models, through an easily applicable reality check strategy. Rt-fMRI neurofeedback may support emotion regulation learning and bears clinical potential for psychotherapy. PMID- 30287302 TI - Perceived timing of active head movement at different speeds. AB - The central nervous system must determine which sensory events occur at the same time. Actively moving the head corresponds with large changes in the relationship between the observer and the environment, sensorimotor processing, and spatiotemporal perception. Active head movement perception has been shown to be dependent on head movement velocity where participants who move their head fastest require the head to move earlier than comparison stimuli for perceived simultaneity more so than those who move their head slower. Such between-subject results cannot address whether active head movement perception changes with velocity. The present study used a within-subjects design to measure the point of subjective simultaneity (PSS) between active head movement speeds and a comparison sound stimulus to characterize the relationship between the velocity and perception of head movement onset. Our results clearly show that i) head movement perception is faster with faster head movements within-subjects, ii) active head movement onset must still precede the onset of other sensory events (average PSS: -123 ms to -52 ms; median PSS: -42 ms to -100 ms) in order to be perceived as occurring simultaneously even at the fastest speeds (average peak velocity: 76 degrees /s-257 degrees /s; median peak velocity 72 ms-257 ms). We conclude that head movement perception is slow, but that this delay is minimized with increased speed. These within-subject results are contrary to previous and present study between-subject results and are in agreement with literature where perception of auditory, visual and vestibular stimulus onset is less delayed with increased stimulus intensity. PMID- 30287301 TI - Community and household-level socioeconomic disadvantage and functional organization of the salience and emotion network in children and adolescents. AB - Socioeconomic disadvantage (SED) during childhood has been linked to disparities in physical and mental health. A growing body of research has focused on identifying neurodevelopmental consequences of SED, commonly measured using within-household factors (e.g., household income), to better understand the processes underlying SED-related disparities. These studies suggest that childhood SED has a widespread impact on brain development, altering development of multiple brain regions simultaneously. These findings also raise the possibility that childhood SED impacts development of key brain systems, such as the salience and emotion network (SEN), which is positioned at the intersection of brain systems involved in cognitive and emotion-related functioning and is thought to mediate information flow within and between these networks. The present study tests for associations between household- and community-level SED, as well as their interaction, and measures of SEN-based functional neural organization in 57 children and adolescents (ages 6-17). We applied graph theoretical analyses to resting-state functional magnetic resonance imaging (fMRI) data to examine SEN-based functional network topology. Results showed that youth residing in more distressed communities demonstrate lower hub-like properties (i.e., less efficient global information transfer and fewer connections) of two core SEN nodes - the anterior cingulate cortex and the left supramarginal gyrus. Similarly, lower household income was associated with lower efficiency of the anterior cingulate, but had no effect on the supramarginal gyrus. There was, however, an interaction between income and community SED in the rostral prefrontal cortex, such that higher income was associated with higher clustering coefficient and lower betweenness centrality, suggesting greater local processing and lower influence of this region on information flow across the network. These effects were significant only among youth living in low (but not high) SED communities, suggesting that within-household SED factors may not protect against the detrimental effects of a disadvantaged community context. Similarly, the age-related increase in average path length of the left rostral prefrontal cortex was only significant among youth living in low (but not high) SED communities. Given that maturation of the SEN is considered to be a critical functional backbone supporting the development of more flexible cognitive and emotional processes into adulthood, we tested for links between SEN graph metrics and measures of cognitive and emotion-related functioning. We found that higher community SED and lower income were both associated with lower IQ. Lower IQ, in turn, was associated with global efficiency of the left supramarginal gyrus. Observed effects of SED on SEN-based functional neural organization may help to explain the strong and pervasive link between childhood SED and disparities in cognitive and emotional outcomes. PMID- 30287303 TI - Gait bradykinesia and hypometria decrease as arm swing frequency and amplitude increase. AB - People with Parkinson's disease (PD) have decreased arm swing movements during walking, which can be related to PD motor signs and symptoms. In this context, the aim of this study was to determine the effects of an increased arm swing frequency or amplitude on the gait parameters in people with PD and healthy older adults. Seventeen individuals with PD and 19 older people were invited to walk on a 10 m pathway under three experimental conditions: (i) usual walking (no arm swing instructions); (ii) an increased arm swing amplitude; and (iii) an increased arm swing frequency. Both groups had an increased stride speed, vertical center of mass and arm swing accelerations and decreased double support time under the increased arm swing amplitude and frequency conditions. People with PD were able to modulate the gait parameters according to the experimental conditions, but at a smaller magnitude than the older individuals. These results indicate that bradykinesia and hypometria of gait can be positively overcome by increasing the amplitude and frequency of arm swing. Arm movements should be included in gait rehabilitation protocols for PD. PMID- 30287304 TI - Increased oxidation of RNA despite reduced mitochondrial respiration after chronic electroconvulsive stimulation of rat brain tissue. AB - Major depressive disorder (MDD) affects 350 million people worldwide and is a serious socio-economic burden. The most efficient treatment of MDD is electroconvulsive therapy (ECT), which has been shown to influence the oxidative status believed to be part of the pathophysiology of MDD. We investigated the effects of chronic electroconvulsive stimulation (ECS) on mitochondrial respiration and mitochondrial hydrogen peroxide production, RNA oxidation, and the content of mitochondria in the piriform cortex of the rat. We found reductions of mitochondrial respiration in respiratory states 2 and 3 by 33% and 32%, respectively, and a 23% reduction in electron transfer capacity. RNA oxidation, as measured by 8-oxo-7,8-dihydroguanosine, was increased by 58%, while mitochondrial production of H2O2 was unaffected. The increased oxidative stress may thus be ascribed to extra-mitochondrial sources. PMID- 30287305 TI - Changes in multiunit activity pattern in cerebellar cortex associated to olfactory cues during sexual learning in male rats. AB - The cerebellum is a structure of the central nervous system which has been previously studied with different techniques and animal models and even humans, so it is associated with multiple functions such as cognition, memory, emotional processing, balance, control of movement, among others. Its relationship with sensory systems has already been explored, however, the role it plays in olfactory processing in the cerebellum is unclear. Several hypotheses have been proposed from work done in humans and animal models with neuroimaging and immunohistochemical techniques. Everything seems to indicate that the cerebellar function is of vital importance for the olfactory perception, being able to be controlling not only the olfactory aspect, but also the olfactory processing. In this study we analyzed the multiunit activity in the granular layer of the cerebellar vermis during olfactory stimulation: a session being sexually naive and during four sessions of sexual behavior learning. The amplitude was compared between male naive and sexual experts, as well as between olfactory stimuli. The amplitude of the sexually experienced rats showed the highest values compared to naive ones. Odor of receptive female causes the greatest amplitudes, however, in the control group the amplitude increased when they were sexually experts. The motor, sensory and associative learning generated by the acquisition of sexual experience modifies the activation pattern in the cerebellum by presenting neutral odors or associated with a reward. PMID- 30287306 TI - Repurposing of dexpramipexole to treatment of neonatal hypoxic/ischemic encephalopathy. AB - Dexpramipexole (DEX) is a drug with a good safety profile in humans, known for its ability to increase mitochondrial ATP production and prompt neuroprotection in adult rodents subjected to cerebral ischemia. In the present study we evaluated the effect of DEX in rat pups subjected to common carotid artery occlusion plus hypoxia (CCAoH, the classic Rice-Vannucci model). Because of the wide range of infarct size distribution in the CCAoH model, a priori subanalysis based on the effect of DEX on mild/moderate or severe brain injuries was conducted. The subanalysis showed that the drug (3 mg/kg bid i.p, after the hypoxic insult) decreased the infarction size in pups with mild/moderate injuries. Next, we developed a distal middle cerebral artery occlusion plus hypoxia (dMCAoH) model, characterized by an intra-experimental infarct size variability lower than that of the CCAoH model. Post-ischemic treatment with DEX (3 mg/kg bid i.p, after the hypoxic insult) reduced brain infarcts in pups exposed to dMCAoH. For the first time, we show that DEX reduces brain injury in different models of neonatal HIE. In light of the favorable safety profile of DEX in humans, the drug might have a realistic translational potential to treatment of perinatal cerebrovascular disorders. PMID- 30287308 TI - Beyond JAAD January 2019. PMID- 30287307 TI - Does acute heat stress differentially-modulate expression of ionotropic neurotransmitter receptors in the RVLM of young and aged F344 rats? AB - The rostral ventral lateral medulla (RVLM) is a brainstem area that plays a role in regulating numerous physiological systems, especially their responsiveness to acute stress. Aging affects the responsiveness of RVLM neural circuits to acute stress. Based on the relationship between ionotropic neurotransmitter receptors in the RVLM and the physiological functions mediated via activation of these receptors, we hypothesized that in response to acute heat stress the expression of ionotropic neurotransmitter receptors in the RVLM of aged rats would be characterized by upregulation of inhibitory subunits and downregulation of excitatory subunits. The goal of the present study was to determine the effect of acute heating on the gene expression profile of RVLM inhibitory (GABAA and Glycine) and excitatory (NMDA and AMPA) ionotropic neurotransmitter receptor subunits in young and aged F344 rats. RVLM tissue punches from young and aged F344 rats were analyzed using TaqMan qPCR and immunoblotting. When compared to age-matched controls, heat stress increased the gene expression of RVLM inhibitory receptor subunits in aged (Gabra1, Gabra2, Gabra5, Glra1) and young (Gabra1) F344 rats at mRNA level, with little change in the expression of RVLM excitatory receptor subunits. Significant age x heat interaction effects were observed with increased expression of Gabra2 and Gabrb1 inhibitory receptor subunits and decreased expression of Gria1 and Gria2 excitatory receptor subunits in the RVLM of aged F344 rats, with the most marked change observed with the Gabra2 subunit, which was validated by immunoblotting. These findings demonstrate that in response to acute heat stress there is enhanced expression of inhibitory ionotropic receptor subunits in aged compared to young rats, supporting the idea that advanced age may alter RVLM responsivity by affecting the molecular substrate of ionotropic receptors. PMID- 30287309 TI - A systematic review and meta-analysis of the regional and age-related differences of atopic dermatitis clinical characteristics. AB - BACKGROUND: Previous studies found conflicting results about the commonality of different atopic dermatitis (AD) signs and symptoms. OBJECTIVE: To determine the prevalences of AD characteristics and differences by region and age. METHODS: A systematic review was performed of all published studies in MEDLINE, EMBASE, SCOPUS, LILACS, Cochrane, China National Knowledge Infrastructure, Taiwan electronic periodical services and CiNii that analyzed the proportion of AD characteristics. Two reviewers performed study title/abstract review and data abstraction. RESULTS: One hundred and one studies reported proportion of AD features with sufficient data for meta-analysis. The most prevalent AD features were pruritus, lichenification and xerosis. There were differences of AD characteristics by study region. Flexural involvement was less commonly reported in India, America and Iran. East Asian studies reported more erythroderma, truncal, extensor, scalp and auricular involvement. Southeast Asian studies reported more exudative eczema, truncal involvement, lichenification and prurigo nodules. Studies from Iran reported more head, face and neck involvement, pityriasis alba, and xerosis. Studies from Africa reported more papular lichenoid lesions, palmar hyperlinearity, ichthyosis and orbital darkening. LIMITATIONS: Heterogeneity between studies and limited reporting of certain AD clinical characteristics. CONCLUSIONS: AD characteristics are heterogeneous and vary by region and age. PMID- 30287310 TI - Lower Socioeconomic Status is Associated with Delayed Access to Care for Infantile Hemangioma, a Cohort Study. AB - BACKGROUND: Early specialist evaluation during rapid proliferative growth of complicated infantile hemangiomas (IH) is crucial. Health disparities and barriers of access-to-care for children with IH have not been examined. OBJECTIVE: Investigate whether socioeconomic status (SES) is associated with age at subspecialist presentation for IH evaluation. METHOD: Retrospective cohort study of 804 children presenting to a large academic hospital. Primary outcome was age at initial presentation. Covariates included demographic, socioeconomic, geographic, and clinical characteristics. Medicaid or Children's Health Insurance Program (CHIP) were proxies for lower SES. Analysis of covariance, chi2 tests, and generalized ordered logistic regressions were performed. RESULTS: Children with lower SES had higher odds of presenting after 3 months of age (OR 2.11, 95% CI 1.31-3.38). In the subset that qualified for institutional care management program (ICMP), no risk factors were associated with delayed presentation. LIMITATIONS: Use of insurance and economic distress as proxies for SES; exclusion of uninsured children may underestimate racioethnic effects; single academic center study limiting generalizability. CONCLUSIONS: Children with IH and lower SES were more likely to present later to specialists, but those enrolled in an ICMP did not, suggesting that integrated ICMPs may mitigate disparities and delayed access-to-care for IH among lower SES populations. PMID- 30287312 TI - Correction. PMID- 30287311 TI - Association between atopic dermatitis and autoimmune disorders in US adults and children: A cross-sectional study. AB - BACKGROUND: Little is known about the risk and predictors of autoimmune diseases in children and adults. OBJECTIVE: To determine the prevalence, predictors and excess costs of autoimmune disease in AD patients. METHODS: Cross-sectional study of the 2002-2012 National Inpatient Sample, including a ~20% sample of all US hospitalizations (n=87,053,155 adults and children). RESULTS: The prevalence [95% confidence interval {CI95}] of autoimmune disease was higher in adults (7.9% [7.3 8.5%] vs. 5.7 [5.7-5.8%]) and children (2.0% [1.7-2.3%] vs. 1.0% [0.9-1.1%]) with vs. without AD. In multivariable logistic regression models controlling for socio demographics, adult (adjusted odds ratio [CI95]: 1.45 [1.32-1.8]) and pediatric (2.08 [1.73-2.50]) AD were associated with any autoimmune disorder. In particular, AD was associated with 18 of 32 autoimmune disorders examined in adults and 12 of 24 examined in children, including disorders of the skin, endocrine, gastrointestinal, hematologic and musculoskeletal systems. AD patients hospitalized with any autoimmune disorder had higher cost of inpatient care with $2.5-$50 million excess annual costs. CONCLUSIONS: Adults and children with AD had increased cutaneous and extra-cutaneous autoimmune disorders, which were associated with a considerable cost-burden. PMID- 30287313 TI - Infertility and Teratogenicity after Paternal Exposure to Systemic Dermatologic Medications: A Systematic Review. AB - BACKGROUND: This systematic review assesses effects of paternal exposure of dermatologic medications, using the former US Food and Drug Administration (FDA) pregnancy categories as a benchmark. OBJECTIVE: To assess whether systemic dermatologic medications can cause infertility and teratogenicity when taken by men. METHODS: Category D and X dermatologic medications were identified; a systematic review of the literature and reviews of the FDA Adverse Events Reporting System (FAERS) and prescribing information were performed to identify effects on male fertility and teratogenicity. Secondary search was performed to assess for other systemic dermatologic medications causing teratogenicity or infertility following paternal exposure. RESULTS: Thirteen medications met inclusion criteria. Nineteen of 1,032 studies were included after systematic review of the literature. Studies evaluating medication effects with paternal exposure were identified for 10 of 13 evaluated medications, and evidence of a negative effect was identified for 6 medications. LIMITATIONS: We did not encounter any studies for 3 medications that met inclusion criteria. Information submitted to the FAERS may not reflect incidence of side effects. CONCLUSIONS: Many former pregnancy category D and X systemic dermatologic medications also have effects on male fertility. More research and better-quality studies are required in this area, particularly assessing potential teratogenicity. PMID- 30287314 TI - Guideline-based medicine grading on the basis of the guidelines of care for ambulatory atopic dermatitis treatment in the United States. AB - PURPOSE: This study was designed to assess the adherence to evidence-based guidelines of care for atopic dermatitis (AD). METHODS: To characterize AD treatment in the United States, ambulatory visits from the 2006-2015 National Ambulatory Medical Care Survey were analyzed. For each medication prescribed, a grade was assigned on the basis of the American Academy of Dermatology treatment guidelines for topical and systemic medications. Considering all visit prescriptions, I calculated a composite grade, analogous to the US academic grading system (scores A-F). RESULTS: I noted prescribing differences across specialty groups. Systemic corticosteroids were more likely to be prescribed by family and general physicians and less likely by pediatricians. Dermatologists were more likely than other specialties to prescribe nonsedating antihistamines, which lack a guideline base supporting their use. Depending upon modeling of care assumptions, all physician specialty visits earned mean guideline-based grades of B or C in their care of AD patients. LIMITATIONS: The clinical, social, and demographic factors influencing prescribing behavior cannot be completely assessed by using extant data. CONCLUSIONS: This preliminary study demonstrates that physicians might benefit from reviewing guidelines of care; there might be an educational gap in the implementation of these guidelines. PMID- 30287315 TI - Opioid Prescribing for Acute Postoperative Pain After Cutaneous Surgery. AB - BACKGROUND: Little information is available to predict which patients require opioid analgesia following cutaneous surgery. When opioids are indicated, information is lacking regarding the optimal opioid agent selection and dosage. OBJECTIVE: To make recommendations for opioid prescription after cutaneous surgery. METHODS: A PubMed literature search was conducted to review the available literature. Recommendations are presented on the basis of available evidence and the opinion of the authors. RESULTS: Most patients undergoing cutaneous surgery do not require opioid analgesia. For those who do, the pain duration warranting opioid analgesia is generally less than 36 hours. Opioid refill requests warrant a follow-up visit to ascertain the cause of ongoing pain after excisional procedures. LIMITATIONS: The recommendations are not based on prospective randomized trials. CONCLUSIONS: The presented recommendations for opioid prescription practice are derived from available evidence, recommendations, and expert opinion. PMID- 30287316 TI - Cost Analysis of a Store and Forward Teledermatology Consult System in Philadelphia. AB - BACKGROUND: Store-and-forward (SAF) teledermatology (TD) has the potential to increase access to timely, high-quality care for underserved populations. However, the cost-effectiveness of TD for underserved populations is uncertain. OBJECTIVE: This study evaluates the potential cost savings associated with a SAF TD program implemented for an underserved population in the city health clinics of urban Philadelphia. METHODS: We performed a retrospective analysis of SAF TD consultations for 700 outpatients managed in 12 Philadelphia primary care clinics. Primary care providers (PCPs) were asked to specify a treatment plan, as well as the type of care for the patient, in the absence of the TD service. Analysis compared cost of each patient case using the TD consult model versus conventional care. RESULTS: Twenty-seven percent (189/700) of in-person dermatology clinic visits and 3.29% (23/700) of emergency room (ER) visits were avoided using TD. Compared to conventional care, mean expected cost savings were $10.00-$52.65 per TD consult. In sensitivity analyses, these estimated savings remained positive across a range of parameters. LIMITATIONS: The cost analysis relies on several assumptions regarding the cost of care, and indirect costs were not included. CONCLUSION: Teledermatology can be a cost saving model while increasing access to dermatologic care.

PMID- 30287318 TI - The role of TERT promoter mutations in differentiating recurrent nevi from recurrent melanomas: a retrospective, case-control study. AB - BACKGROUND: Repigmentation at previous biopsy sites pose a significant diagnostic dilemma given clinical and histologic similarities between recurrent nevi and locally recurrent melanoma. While common in melanoma, the role of TERT promoter mutations (TPMs) in recurrent nevi is unknown. OBJECTIVE: We investigated the role of TPMs in recurrent nevi and whether the presence of hotspot TPM distinguishes recurrent nevi from locally recurrent melanoma. We also characterized clinical and histologic features differentiating these lesions. METHODS: We analyzed 11 locally recurrent melanomas, 17 recurrent nevi, and melanoma and nevus controls to determine TPM status. We also assessed clinical and histologic features of the recurrent groups. RESULTS: Hotspot TPMs were more common in recurrent melanomas compared to recurrent nevi (p=0.008). Recurrent melanomas were more likely to have solar elastosis (p=0.0047), multi-layering of melanocytes in the epidermis (p=0.0221), adnexal involvement (p=0.0069), and epidermal consumption (p=0.0204). Recurrent nevi had intra-epidermal atypia limited to the area above the scar (p<0.0001) and occurred earlier after the original biopsy (p<0.0008). Solar elastosis, months to recurrence, and hotspot TPM were independently associated with recurrent melanoma in multivariate analysis. LIMITATIONS: This was a retrospective study. CONCLUSION: Hotspot TPMs are significantly more frequent in recurrent melanomas and may serve as a diagnostic clue in histologically ambiguous cases.

PMID- 30287320 TI - Association of multiple primary melanomas with malignancy risk: a population based analysis of the Surveillance, Epidemiology, and End Results Program database from 1973-2014. AB - BACKGROUND: Genetic and environmental risk factors have been associated with the development of multiple primary melanomas (MPM). We hypothesized that individuals with MPM may have increased predisposition to developing internal malignancies. OBJECTIVE: To identify the risk of subsequent malignancies in MPM patients. METHODS: Multiple primary standardized incidence ratios were analyzed for individuals with >=1, >=2 and >=3 primary melanomas (PM) in the SEER database from 1973-2014. RESULTS: 223,799 individuals with >=1, 19,709 with >=2 and 3,995 with >=3 PM were identified. Risks of subsequent internal malignancy increased with number of PM, with observed to expected (O/E) ratios of 0.99, 1.14, and 1.23 (p<0.05) for patients with at least one, two and three PM respectively. Internal malignancy was higher in younger MPM patients and those with superficial spreading melanoma. The most common malignancies amongst MPM patients include breast, prostate, thyroid, soft tissue, brain, kidney, non-Hodgkin's lymphoma, and chronic lymphocytic leukemia. Risk of subsequent cutaneous melanoma increased with O/E ratios of 8.09, to 22.52, to 41.03 (p<0.05) respectively. LIMITATIONS: SEER records limited information about pigmentation phenotypes, histology, and treatments. CONCLUSION: Patients with MPM have increased risk of subsequent internal and cutaneous malignancies and may benefit from tight adherence to age specific cancer screening.

AB - BACKGROUND: Infant death in KID syndrome is recognized; its association with specific genotypes and pathophysiology is inadequately understood. OBJECTIVE: To discover characteristics that account for poor outcomes in lethal KID syndrome. METHODS: We collected four new cases and nine previously reported, genotyped cases of lethal KID syndrome. We performed new molecular modeling of the lethal mutants GJB2 p.A88V and GJB2 p.G45E. RESULTS: Infant death occurred in all patients with GJB2 p.G45E and p.A88V; it is unusual with other GJB2 mutations. Early death with those two "lethal" mutations is likely multifactorial: during life all had at least one serious infection; most had poor weight gain and severe respiratory difficulties; many had additional anatomic abnormalities. Structural modeling of GJB2 p.G45E identified no impact on the salt bridge previously predicted to account for abnormal central CO2 sensing of GJB2 p.A88V. LIMITATIONS: Clinical review was retrospective. CONCLUSION: GJB2 p.G45E and p.A88V are the only KID syndrome mutations associated with uniform early lethality. Those electro-physiologically severe mutations in GJB2 reveal abnormalities in many organs in lethal KID syndrome. All KID syndrome patients may have subtle abnormalities beyond eyes, ears and skin. Early genotyping of KID syndrome births will inform prognostic discussion. PMID- 30287324 TI - "Treatment of male pattern alopecia with platelet-rich plasma: a double blind controlled study with analysis of platelet number and growth factor levels". AB - BACKGROUND: Promising results were described with platelet-rich plasma (PRP) in androgenetic alopecia that could be associated to platelet number and growth factor levels. OBJECTIVE: Analyze the platelet number and growth factor levels in PRP and its correlation with hair growth parameters evaluated by TrichoScan. METHODS: Twenty-six patients randomized to receive four subcutaneous injections of PRP or saline. Hair growth, hair density, and percentage of anagen hairs were evaluated before, after and three months after the last injection using TrichoScan method. Growth factors (PDGF, EGF and VEGF) were measured by Luminex method. RESULTS: We demonstrated a significant increase in hair count (p = 0.0016), hair density (p = 0.012) and percentage of anagen hairs (p = 0.007) in PRP group when compared to control group, without correlation with platelet counts or quantification of the growth factors in PRP. CONCLUSION: Our data favors the use of PRP as therapeutic alternative in the treatment of androgenetic alopecia. The lack of association between platelet count, PDGF, EGF and VEGF levels and clinical improvement suggest that other mechanisms could be involved in this response. LIMITATIONS: Other growth factors that could be related with PRP response were not evaluated. PMID- 30287325 TI - Acne Disparities in Native Americans.

AB - BACKGROUND: Evidence establishing the link between acne vulgaris (AV) and hidradenitis suppurativa (HS) is limited, and the burden of AV in this group is unknown. OBJECTIVE: To determine prevalence of AV among adults with HS, and to determine the strength of this association. METHODS: Cross-sectional analysis identifying adults with AV among HS and non-HS patients using electronic health records data from a population-based sample of over 55 million patients. RESULTS: Prevalence of AV among adults with HS was 15.2% (7,315 /48,050), compared to 2.9% (497,360 /16,899,470) for adults without HS (p<0.001). Prevalence was greatest among HS patients who were female (5,870/35,790; 16.4%), ages 18-44 years (5,260/28,870; 18.2%), non-white (3,120/17,825); 17.5%), obese (5,430/35,135; 15.5%), and had PCOS (685/2,385; 28.7%). HS patients had 4.51 [95% CI 4.40-4.63] times the odds of having AV compared to non-HS patients, and the higher likelihood of having AV persisted across all HS subgroups. The association between HS and AV was generally stronger for patients who were male, aged >= 65 years, non-whites, and obese. LIMITATIONS: Influence of disease severity in HS, or in acne, on the strength of the association could not be assessed. CONCLUSION: Patients with HS may benefit from assessment of acne status and optimization of co-management strategies. PMID- 30287329 TI - Breastfeeding initiation and duration and child health outcomes in the first baby study. AB - Despite the known benefits of breastmilk, associations between breastfeeding and child overall health outcomes remain unclear. We aimed to understand associations between breastfeeding and health outcomes, including child weight, through age 3. Analysis included women (N = 3006) in the longitudinal, prospective First Baby Study from 2009 to 2014. For this analysis, breastfeeding initiation and duration were measured using self-reported data from the 1-, 6- and 12-month surveys; child illnesses were analyzed from the 6-, 12-, and 24-month interviews; height and weight at age 3 were used to determine overweight/obese (>=85th percentile) and obese (>=95th percentile). Adjusted logistic regressions were utilized to determine significance. Greater duration of breastfeeding was associated with fewer reported acute illnesses at 6 months (p < 0.001) and fewer diarrheal illness/constipation episodes at 6, 12, and 24 months (p = 0.05) in adjusted analyses. Fewer breastfed children, compared to non-breastfed children, were overweight/obese (23.5% vs. 37.8%; p = 0.032) or obese (9.1% vs. 21.6%; p = 0.012) at age 3. Breastfeeding duration was negatively associated with overweight/obese (never breastfed: 37.8%, 0-6 months: 26.9%, >6 months: 20.2%; p = 0.020) and obesity (never breastfed: 21.6%, 0-6 months: 11.0%, >6 months: 7.3%; p = 0.012). Overall, our findings support the hypothesis that duration of breastfeeding is associated with fewer reported acute illnesses at 6 months of age and diarrheal illness and/or constipation episodes at 6, 12, and 24 months. Additionally, results from our study suggest a protective effect of breastfeeding from childhood overweight/obesity, as children who received breastmilk for 6 months or longer had lower odds of overweight/obesity at age 3 years. PMID- 30287330 TI - Reduction in purchases of energy-dense nutrient-poor foods in Mexico associated with the introduction of a tax in 2014. AB - In 2014, an 8% tax on energy-dense nutrient-poor foods was implemented in Mexico with the aim of reducing its consumption. This paper estimated changes in household purchases of taxed food. We used the latest five waves of the nationally representative Mexican Income and Expenditure Survey (2008, 2010, 2012, 2014 and 2016). The analytic sample comprises 154,777 households. We estimated changes in purchases based on a before and after comparison. Results show a reduction in purchases of taxed food of -5.4 g/week per capita, equivalent to a relative reduction of -5.3% in the 2014 and 2016 waves compared to the 2008, 2010 and 2012 rounds. The largest relative reductions were in urban areas ( 6.9%), among households with children (-7.0%), households where the head had an intermediate educational level (-9.9%) and the southern region (-14.8%). We did not find a significant reduction in rural areas. While there is a large heterogeneity, the fiscal instrument has been effective in reducing taxed food purchases and has generated substantial revenue that could be used to finance policies for the prevention and treatment of obesity. PMID- 30287331 TI - Indicated preventive interventions for depression in children and adolescents: A meta-analysis and meta-regression. AB - Depression contributes about 2% to the global burden of disease. A first onset of depressive disorder or subsyndromal depressive symptoms is common in adolescence, indicating that early prevention is a priority. However, trials of preventive interventions for depression in youths show conflicting results. This systematic review and meta-analysis investigated the effectiveness of group-based cognitive behavioral therapy (GB-CBT) as a preventive intervention targeting subsyndromal depression in children and adolescents. In addition, the impact of different covariates (type of comparator and use of booster sessions) was assessed. Relevant articles were identified from previous systematic reviews, and supplemented with an electronic search spanning from 01/09/2014 to 28/02/2018. The retrieved articles were assessed for eligibility and risk of bias. Relevant data were extracted. Intervention effectiveness was pooled using a random-effects model and the impact of covariates assessed using meta-regression. 38 eligible articles (34 trials) were obtained. The analysis showed GB-CBT to significantly reduce the incidence (relative risk 0.43, 95% CI 0.21-0.87) and symptoms (Cohen's d -0.22, 95% CI -0.32 to -0.11) of depression at post-test compared to all controls. Comparisons with passive comparators suggested that the effect decayed over time. However, compared to active controls, a significant intervention effect was evident only after 12 month or more. Our results suggest that the preventive effect of GB-CBT wears off, but still lasts longer than the effect of active comparators. Only a few studies included booster sessions, precluding firm conclusions. Future studies should clarify to what extent maintenance strategies can prolong the preventive effect of GB-CBT.

AB - Ethyl 2-methyl-1,3-dioxolane-2-acetate (CAS # 6413-10-1) was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that ethyl 2-methyl-1,3-dioxolane-2-acetate is not genotoxic. Data from ethyl 2-methyl-1,3-dioxolane-2-acetate show that there are no safety concerns for skin sensitization under the current, declared levels of use. Data on ethyl 2-methyl-1,3-dioxolane-2-acetate provide a calculated MOE >100 for the repeated dose, developmental, and reproductive toxicity endpoints. The local respiratory toxicity endpoints were evaluated using the TTC for a Cramer Class III material, and the exposure to ethyl 2-methyl-1,3-dioxolane-2-acetate is below the TTC (0.47 mg/day). The phototoxicity/photoallergenicity endpoints were evaluated based on UV spectra; ethyl 2-methyl-1,3-dioxolane-2-acetate is not expected to be phototoxic/photoallergenic. For the environmental endpoints, ethyl 2-methyl-1,3-dioxolane-2-acetate is not PBT as per the IFRA Environmental Standards, and its risk quotients (i.e., PEC/PNEC) for the aquatic environment based on its current volume of use in Europe and North America are <1.

PMID- 30287338 TI - Ochratoxin A induces cytoprotective autophagy via blocking AKT/mTOR signaling pathway in PK-15 cells. AB - Ochratoxin A (OTA) could cause a variety of toxicological effects especially nephrotoxicity in animals and humans. Autophagy is a highly conserved metabolic process that plays an important role in the maintenance of cellular homeostasis under stress. However, the role of autophagy in OTA-induced nephrotoxicity is unknown. In the present study, we demonstrated that OTA treatment at 2.0-8.0 MUM could increase cytotoxicity of PK-15 cells by inducing apoptosis as shown by the increased Annexin V/PI staining, increased caspase-3 and PARP cleavage and increased apoptotic nuclei. Meantime, autophagy was triggered when OTA was administrated, as indicated by markedly increased expressions of LC3-II, ATG5 and Beclin-1, accumulation of GFP-LC3 dots and increased double- or single-membrane vesicles. OTA treatment decreased p-AKT and p-mTOR activities, and OTA-induced autophagy was inhibited when insulin was applied. Furthermore, OTA treatments with autophagy inhibitors (3-methyladenine or chloroquine) or knockdown of autophagy-related genes (ATG5 or Beclin-1) resulted in significantly reduced autophagy level and enhanced cytotoxicity. In conclusion, OTA induces cytoprotective autophagy against its cytotoxicity and inactivation of AKT/mTOR axis plays a critical role in autophagy induction. PMID- 30287339 TI - Loss of hepatocyte beta-catenin protects mice from experimental porphyria associated liver injury. AB - BACKGROUND & AIMS: Porphyrias result from anomalies of heme biosynthetic enzymes and can lead to cirrhosis and hepatocellular cancer. In mice, these diseases can be modeled by administration of a diet containing 3,5-diethoxycarbonyl-1,4 dihydrocollidine (DDC), which causes accumulation of porphyrin intermediates, resulting in hepatobiliary injury. Wnt/beta-catenin signaling has been shown to be a modulatable target in models of biliary injury; thus, we investigated its role in DDC-driven injury. METHODS: beta-Catenin (Ctnnb1) knockout (KO) mice, Wnt co-receptor KO mice, and littermate controls were fed a DDC diet for 2 weeks. beta-Catenin was exogenously inhibited in hepatocytes by administering beta catenin dicer-substrate RNA (DsiRNA), conjugated to a lipid nanoparticle, to mice after DDC diet and then weekly for 4 weeks. In all experiments, serum and livers were collected; livers were analyzed by histology, western blotting, and real time PCR. Porphyrin was measured by fluorescence, quantification of polarized light images, and liquid chromatography-mass spectrometry. RESULTS: DDC-fed mice lacking beta-catenin or Wnt signaling had decreased liver injury compared to controls. Exogenous mice that underwent beta-catenin suppression by DsiRNA during DDC feeding also showed less injury compared to control mice receiving lipid nanoparticles. Control livers contained extensive porphyrin deposits which were largely absent in mice lacking beta-catenin signaling. Notably, we identified a network of key heme biosynthesis enzymes that are suppressed in the absence of beta-catenin, preventing accumulation of toxic protoporphyrins. Additionally, mice lacking beta-catenin exhibited fewer protein aggregates, improved proteasomal activity, and reduced induction of autophagy, all contributing to protection from injury. CONCLUSIONS: beta-Catenin inhibition, through its pleiotropic effects on metabolism, cell stress, and autophagy, represents a novel therapeutic approach for patients with porphyria. LAY SUMMARY: Porphyrias are disorders resulting from abnormalities in the steps that lead to heme production, which cause build-up of toxic by-products called porphyrins. Liver is commonly either a source or a target of excess porphyrins, and complications can range from minor abnormalities to liver failure. In this report, we inhibited Wnt/beta catenin signaling in an experimental model of porphyria, which resulted in decreased liver injury. Targeting beta-catenin affected multiple components of the heme biosynthesis pathway, thus preventing build-up of porphyrin intermediates. Our study suggests that drugs inhibiting beta-catenin activity could reduce the amount of porphyrin accumulation and help alleviate symptoms in patients with porphyria. PMID- 30287341 TI - Healthcare resource utilization and costs by disease severity in an insured national sample of US patients with chronic hepatitis B. AB - BACKGROUND & AIMS: Chronic hepatitis B (CHB) affects over 2 million people in the US, with little reported on healthcare utilization and cost. We aimed to quantify annual CHB utilization and costs by disease severity and payer type. METHODS: Using Commercial, Medicare, and Medicaid databases from 2004 to 2015 and ICD9 codes, we retrospectively identified adults with CHB, analyzing all-cause inpatient, outpatient, and pharmaceutical utilization and costs by disease severity. We compared healthcare utilization and costs between patients with CHB, without advanced liver disease, and matched non-CHB controls. All-cause inpatient, outpatient, and pharmaceutical utilization and costs were reported for each year and adjusted to 2015 dollars. RESULTS: Our sample consisted of 33,904 CHB cases and 86,072 non-CHB controls. All-cause inpatient admissions (average stay 6-10 days) were more frequent in advanced liver disease states. Across all payers, patients with decompensated cirrhosis had the highest emergency department utilization (1.6-2.8 annual visits) and highest mean annual costs. The largest all-cause cost components for Commercial and Medicaid were inpatient costs for all advanced liver disease groups (Commercial: 62%, 47%, 68%; Medicaid: 81%, 72%, 74%, respectively), and decompensated cirrhosis and hepatocellular carcinoma groups for Medicare (Medicare 49% and 48%). In addition, patients with compensated liver disease incurred costs 3 times higher than non-CHB controls. CONCLUSION: Patients with CHB, regardless of payer, who experienced decompensated cirrhosis, hepatocellular carcinoma, or a liver transplant incurred the highest annual costs and utilization of healthcare resources, but even patients with CHB and compensated liver disease incurred higher costs than those without CHB. All stakeholders in disease management need to combine efforts to prevent infection and advanced liver disease through improved vaccination rates, earlier diagnosis, and treatment. LAY SUMMARY: Hepatitis B virus can be a progressive disease leading to cirrhosis, hepatocellular carcinoma, liver transplant, and death. These progressive disease states are associated with a higher rate of hospitalizations, emergency room visits, outpatient visits, and costs compared to similar patients without hepatitis B. The most ill patients have the highest costs, but even patients who are less sick experience higher costs than patients without hepatitis B. PMID- 30287340 TI - Ketoconazole exacerbates mitophagy to induce apoptosis by downregulating cyclooxygenase-2 in hepatocellular carcinoma. AB - BACKGROUND & AIMS: Hepatocellular carcinoma (HCC) is a common cancer worldwide and remains a major clinical challenge. Ketoconazole, a traditional antifungal agent, has attracted considerable attention as a therapeutic option for cancer treatment. However, its mechanism of action is still not clearly defined. We aimed to evaluate the effect of ketoconazole on HCC and investigate the underlying mechanisms. METHODS: We examined the antitumor effect of ketoconazole on HCC cells, cell line-derived xenografts, and a patient-derived xenograft (PDX) model. Ketoconazole-induced mitophagy was quantified by immunofluorescence, immunoblotting and transmission electron microscopy analysis. We used mitophagy inhibitors to study the role of mitophagy on HCC cell death induced by ketoconazole. The role of cyclooxygenase-2 (COX-2 [encoded by PTGS2]) on ketoconazole-induced mitophagy was evaluated using gain- and loss-of-function methods. The synergistic effect of ketoconazole with sorafenib on HCC was measured in vivo and in vitro. RESULTS: Ketoconazole stimulated apoptosis in HCC cells by triggering mitophagy in vitro and in vivo. Mechanistically, ketoconazole downregulated COX-2, which led to PINK1 accumulation and subsequent mitochondrial translocation of Parkin (PRKN), and thereby promoted mitophagy-mediated mitochondrial dysfunction. Inhibiting mitophagy alleviated ketoconazole-induced mitochondrial dysfunction and apoptosis, supporting a causal role for mitophagy in the antitumor effect of ketoconazole. In the HCC PDX model, ketoconazole demonstrated a marked antitumor effect characterized by COX-2 downregulation, mitophagy activation, and apoptosis induction. Moreover, ketoconazole acted synergistically with sorafenib to suppress HCC xenograft growth in vivo. CONCLUSION: Our results demonstrate a novel link between ketoconazole and mitophagy machinery, providing preclinical proof of concept for the use of ketoconazole in HCC treatment. LAY SUMMARY: Hepatocellular carcinoma (HCC) is a common malignancy worldwide and remains a major clinical challenge. Our study reveals that ketoconazole, a broad-spectrum antifungal agent, activates PINK1/Parkin-mediated mitophagy by downregulating COX-2, consequently resulting in the acceleration of apoptosis and thereby inhibiting the growth of HCC. Furthermore, ketoconazole acts synergistically with sorafenib in the suppression of HCC growth in vitro and in vivo. PMID- 30287342 TI - Transcranial direct-current stimulation (tDCS) improves detection of simple bright stimuli by amblyopic Long Evans rats in the SLAG task and produces an increase of parvoalbumin labelled cells in visual cortices. AB - In this work visual functional improvement of amblyopic Long Evans rats treated with tDCS has been assessed using the "slow angled-descent forepaw grasping" (SLAG) test. This test is based on an innate response that does not requires any memory-learning component and has been used before for measuring visual function in rodents. The results obtained show that this procedure is useful to assess monocular but not binocular deficits, as controls and amblyopic animals showed significant differences during monocular but not during binocular assessment. On the other hand, parvoalbumin labelling was analysed in three areas of the visual cortex (V1M, V1B and V2L) before and after tDCS treatment. No changes in labelling were observed after monocular deprivation. However, tDCS treatment significantly improved vision through the amblyopic eye, and a significant increase of parvoalbumin-positive cells was observed in the three areas, both in the stimulated hemisphere but also in the non-stimulated hemisphere. This effect occurred both in control and amblyopic animals. Thus, tDCS induced changes are similar in controls and amblyopic animals, although only the last one showed a functional improvement. PMID- 30287343 TI - Oxidative stress in status epilepticus: a clinical-radiological correlation. AB - PURPOSE: To report oxidative stress in the patients with status epilepticus (SE), and correlate these with severity, MRI and outcome. METHODS: Thirty-five patients with SE and 34 controls were included. Blood sample was collected at admission for measuring superoxide dismutase (SOD), catalase, protein carbonyl, glutathione, total antioxidant capacity (TAC), malondialdehyde (MDA) and nitric oxide (NO). The type of SE, duration and Status Epilepticus Severity Score (STESS) at admission and refractoriness to treatment were noted. Cranial magnetic resonance imaging (MRI) findings, in-hospital deaths and disability at discharge were noted. RESULTS: The median age of the patients was 35 and 14 were females. The median STESS was 3 (0-5), and the score was unfavorable in 21(60%) patients. MRI was abnormal in 27(77%) patients. The patients with SE had significantly lower concentrations of SOD, catalase, protein carbonyl, GSH and TAC and higher concentrations of MDA and NO compared to the controls. These levels did not differ between refractory and non-refractory SE. Glutathione level inversely correlated with age. Malondialdehyde and NO levels positively correlated with age and inversely with GSH level. Five (14.3%) patients died in hospital. At discharge, 14 patients had good and 16 had poor outcome. The oxidative stress markers did not correlate with death or disability. CONCLUSION: Oxidative stress is increased in the patients with SE. Further study is needed in larger sample size to explore probable adjunctive treatment option. PMID- 30287344 TI - Hydrogen-rich saline protects rat from oxygen glucose deprivation and reperusion induced apoptosis through VDAC1 via Bcl-2. AB - BACKGROUND: Hydrogen is received as an inert gas that thought to be non functional in vivo previously. Recently, emerging evidences showed that in ischemia/reperfusion (IR) condition, hydrogen reduced cellular reactive oxygen species (ROS) production and ameliorated cell apoptosis. However, the underlying mechanism of hydrogen on IR-induced apoptosis remains elusive. Here we tried to unravel the mode of action of hydrogen with rat adrenal medulla cell line PC-12 in vitro. METHODS: The mitochondrial functions before and after oxygen glucose deprivation and reperfusion (OGD/RP) were determined with corresponding dyes. The expression of Bcl-2, Bax, VDAC1, cytochrome c and caspase 9 was detected using Western Blotting method. Then Bcl-2 inhibitor, AB-199, was applied to investigate the role of Bcl-2 in OGD/RP-induced cell apoptosis. Finally, we manipulated the expression of VDAC1 with plasmids transfection to understand the effects of VDAC1 on Bcl-2-mediated anti-apoptosis in OGD/RP. RESULTS: In this study, we demonstrated that hydrogen-rich saline (HRS) reduced OGD/RP-mediated neuronal loss by stimulating the expression of Bcl-2, which suppressed the activity of VDAC1. Consequently, hydrogen maintained the mitochondrial functions, restrains the release of cytochrome c and caspase 9 activation, resulting in ameliorated cell viability. CONCLUSIONS: HRS ameliorated OGD/RP-induced PC-12 cell apoptosis and provides a novel treatment option for ischemia. PMID- 30287345 TI - Coconut Oil Decreases Expression of Amyloid Precursor Protein (APP) and Secretion of Amyloid Peptides throughInhibitionof ADP-ribosylation factor 1 (ARF1). AB - : Alzheimer's disease (AD), affecting 5.3 million people in the U.S., impairs portions of the brain controlling memories. In humans, mutations in the amyloid precursor protein (APP) gene has been implicated in increased plaque formation, which can block the communication between nerve cells, decrease dendritic formation and increase cell death, and promote neuroinflammation. As coconut oil has been suggested to alleviate the symptoms in AD patients, we examined the impact of coconut oil on APP expression and secretion of amyloid peptides in N2a cells expressing the human APP gene (N2a/APP695). We found that coconut oil treatment decreased APP expression in N2a cells and reduced the secretion of Amyloid Peptides Abeta40 and Abeta42. Moreover, coconut oil treatment promoted differentiation of N2a cells. Our data suggest that ADP-Ribosylation Factor 1 (ARF1) may contribute to the effects of coconut oil on APP expression and secretion of Abeta. A high ARF1 expression was also detected in the primary neuronal cells from the mice overexpressing the Swedish mutant APP. Immunostaining results revealed that APP is co-localized with ARF1 in the Golgi Apparatus and this interaction is impaired after coconut oil treatment. Furthermore, knockdown of ARF-1 using siRNA decreased secretion of amyloid peptides, confirming the impact of ARF1 on the secretion of amyloid peptides. CONCLUSION: These results suggest that coconut oil decreases intracellular ARF1 expression, thereby resulting in an inhibition of APP and amyloid beta secretion. This study reveals a novel mechanism for intracellular APP processing in neuronal cells. PMID- 30287346 TI - Comparative analysis of spleen transcriptome detects differences in evolutionary adaptation of immune defense functions in bighead carp and silver carp. AB - The evolutionary divergence of the immune defense functions in bighead carp (A. nobilis) and silver carp (H. molitrix) is still not understood at the molecular level. Here, we obtained 48,821,754 and 55,054,480 clean reads from spleen tissue libraries prepared for bighead carp and silver carp using Illumina paired-end sequencing technology, respectively, and identified 4976 orthologous genes from the transcriptome data sets by comparative analysis. Adaptive evolutionary analysis showed that 212 orthologous genes and 255 Gene Ontology (GO) terms were subjected to positive selection(Ka/Ks values > 1) only in bighead carp, and 195 orthologous genes and 309 GO terms only in silver carp. Among immune defense functions with significant evolutionary divergence, the positively selected biological processes in bighead carp mainly included B cell-mediated immunity, chemokine-mediated signaling pathway, and immunoglobulin mediated immune response, whereas those in silver carp mainly included the antigen processing and presentation, defense response to fungus, and detection of bacteria. Moreover, we found 2974 genes expressed only in spleen of bighead carp and 3494 genes expressed only in spleen of silver carp, where these genes were mostly enriched in the same biological processes or pathways. These results provide a better understanding of the differences in resistance to some diseases by bighead carp and silver carp, and also facilitate the identification of candidate genes related to disease resistance. PMID- 30287347 TI - Identification, characterisation and preliminary functional analysis of IRAK-M in grass carp (Ctenopharyngodon idella). AB - Interleukin-1 receptor-associated kinase (IRAK) family members play important roles in myeloid differentiation primary response 88 (MyD88)-dependent toll-like receptor (TLR) signaling, the crucial innate immune pathway in vertebrates. In the present study, the IRAK family gene IRAK-M (also called IRAK3) from grass carp (Ctenopharyngodon idella) was cloned and characterised. IRAK-M was mainly enriched in the spleen, and the significantly altered expression was observed after grass carp reovirus (GCRV) infection. Subcellular localisation showed that IRAK-M protein distributed uniformly in the entire cell and co-localised with MyD88 in the cytoplasm of transfected cells. Additionally, the interaction between IRAK-M and MyD88 was confirmed by bimolecular fluorescence complementation (BiFC) system. Moreover, deficient of IRAK-M in C. idella kidney cell line (CIK) with small interference RNA (siRNA) upregulated polyinosinic:polycytidylic acid (poly(I:C))-induced inflammatory cytokines production, including interleukin 8 (IL-8), IL-6, and tumour necrosis factor alpha (TNF-alpha), which reveals that IRAK-M functions as a negative regulator of inflammatory cytokines. Taken together, our results demonstrate that IRAK-M gene plays an important role in innate immune regulation and provide new insights into understanding the functional characteristics of the IRAK-M in teleosts. PMID- 30287348 TI - Characterization of four C1q/TNF-related proteins (CTRPs) from red-lip mullet (Liza haematocheila) and their transcriptional modulation in response to bacterial and pathogen-associated molecular pattern stimuli. AB - The structural and evolutionary linkage between tumor necrosis factor (TNF) and the globular C1q (gC1q) domain defines the C1q and TNF-related proteins (CTRPs), which are involved in diverse functions such as immune defense, inflammation, apoptosis, autoimmunity, and cell differentiation. In this study, red-lip mullet (Liza haematocheila) CTRP4-like (MuCTRP4-like), CTRP5 (MuCTRP5), CTRP6 (MuCTRP6), and CTRP7 (MuCTRP7) were identified from the red-lip mullet transcriptome database and molecularly characterized. According to in silico analysis, coding sequences of MuCTRP4-like, MuCTRP5, MuCTRP6, and MuCTRP7 consisted of 1128, 753, 729, and 888 bp open reading frames (ORF), respectively and encoded 375, 250, 242, and 295 amino acids, respectively. All CTRPs possessed a putative C1q domain. Additionally, MuCTRP5, MuCTRP6, and MuCTRP7 consisted of a collagen region. Phylogenetic analysis exemplified that MuCTRPs were distinctly clustered with the respective CTRP orthologs. Tissue-specific expression analysis demonstrated that MuCTRP4-like was mostly expressed in the blood and intestine. Moreover, MuCTRP6 was highly expressed in the blood, whereas MuCTRP5 and MuCTRP7 were predominantly expressed in the muscle and stomach, respectively. According to the temporal expression in blood, all MuCTRPs exhibited significant modulations in response to polyinosinic:polycytidylic acid (poly I:C) and Lactococcus garvieae (L. garvieae). MuCTRP4-like, MuCTRP5, and MuCTRP6 showed significant upregulation in response to lipopolysaccharides (LPS). The results of this study suggest the potential involvement of Mullet CTRPs in post-immune responses.

AB - Androgen-deprivation therapy (ADT) in patients with prostate cancer can be achieved surgically or chemically, notably by prescribing LHRH analogs. Major bone loss occurs rapidly in both cases, due to the decrease in testosterone levels, and can increase the fracture risk. The objective of developing these recommendations was to achieve a practical consensus among various scientific societies, based on a literature review, about osteoporosis prevention and treatment in patients on ADT. The following scientific societies contributed to the work: Societe francaise de rhumatologie (SFR), Groupe de recherche et d'information sur les osteoporoses (GRIO), Groupe europeen d'etudes des metastases osseuses (GEMO), Association francophone pour les soins de support (AFSOS), Association francaise d'urologie (AFU), Societe francaise de radiotherapie oncologique (SFRO). Medication prescription and reimbursement modalities in France were taken into account. The recommendations state that a fracture-risk evaluation and interventions targeting risk factors for fractures should be provided to all patients on ADT. Those patients with a history of severe osteoporotic fracture and/or a T-score < -2.5 should receive osteoporosis therapy. Patients whose T-score is between -1.5 and -2.5 should be treated if they exhibit at least two other risk factors among the following: age >= 75 years, history of non-severe fracture after 50 years of age, body mass index < 19 kg/m2, at least three comorbidities (e.g., cardiovascular disease, depression, Parkinson's disease, and dementia), current glucocorticoid therapy, and repeated falls. When the decision is difficult, FRAX(r) score determination and an assessment by a bone disease specialist may be helpful. When osteoporosis therapy is not indicated, general measures should be applied, and bone mineral density measured again after 12-24 months. The anti-tumor effects of bisphosphonates and denosumab fall outside the scope of these recommendations.

AB - Vibrio campbellii BAA-1116 is renowned for its bioluminescence properties, and genetic tools are available to genetically track this strain. However, many other ecologically important V. harveyi strains exist, for which only few genetic tools are available. In this study, a rapid electroporation protocol was developed to transform replicative plasmids in various environmental V. harveyi and Pseudoalteromonas strains. Moreover, a mini-Tn7 delivery system was modified to site-specifically integrate mini-transposons in the genome of V. harveyi ORM4. As a proof-of-principle, replicative plasmids carrying bioreporters were introduced by electroporation in V. harveyi ORM4 cells, and gene expression was followed at the single cell level. We could demonstrate that a flagellar gene is subjected to bimodal gene expression in V. harveyi ORM4, being highly expressed in 10% of the population in stationary phase. This study extends the possibilities to study environmental Vibrio strains and uncovers the occurrence of phenotypic heterogeneity in flagellar expression in Vibrio. PMID- 30287353 TI - Over expression of the constitutive expression refractory Mycobacterium tuberculosis Rv3488 protein with an acid-inducible expression system. AB - As inducible protein expression plasmids available for mycobacterial species are limited, here we demonstrate the utility of an acid-inducible promoter driving gene and subsequent protein expression of a difficult to express protein. We wanted to assess the use of an acid inducible promoter expression system to produce proteins in a mycobacterial system, specifically proteins that when overexpressed interfere with mycobacterial cell growth. Overexpression of those types of proteins would require a tightly regulated promoter system. We employed the Mycobacterium tuberculosis lipF minimal acid-inducible promoter (mpr) which had previously been shown to be upregulated by acidic stress >100 X and to have a low basal level of expression in the absence of acidic stress. It is active from pH 4.3 up to pH 6.4 making this an acid range that is compatible with mycobacterial growth or survival and active at acidic ranges encountered in vivo within acidified phagosomes of macrophages. We therefore cloned the M. tuberculosis gene Rv3488, whose product had been unable to be expressed constitutively, into a plasmid downstream of the lipF mpr promoter and overexpressed this gene in the presence of acidic pH in Mycobacterium smegmatis. Sustained overexpression of the gene leads to inhibition of replication of mycobacterial cells as well as inhibition of carotenoid pigment synthesis, while short-term overexpression leads to appropriate protein expression. PMID- 30287354 TI - Practical considerations for sampling and data analysis in contemporary metagenomics-based environmental studies. AB - Recent advancements in metagenomic-based studies, especially analyses of amplicon based DNA sequencing targeting taxonomic marker genes, has led to an unprecedented characterization of microbial communities from diverse ecosystems around the world. While originally constrained by a lack of appropriate analytical tools and sequencing depth, new technologies and computational and statistical algorithms have been developed to handle highly dimensional, next generation sequencing datasets. Both these tools allow for the robust analysis of structural and distributional patterns of microbiota essential for the understanding of microbial ecology and biogeography. Furthermore, consortia of individual laboratories working on large interdisciplinary research programs, like the Human and Earth Microbiome Projects, have developed standardized protocols for DNA extraction, sequencing pipelines, and bioinformatics. These approaches provide large repositories of publicly available data to serve as references for on-going and future, hypothesis-driven studies to better characterize the roles of microbial communities in diverse ecosystems. In this review, we outline the currently available statistical approaches and tools to aid in statistically powered study designs and analyses. Given what is now known about the enormous diversity and variability of the microbial communities in aquatic and terrestrial habitats, we also discuss practical considerations for sample collection. Due to the extensive advances made in the field of metagenomics over the last decade, rigorous, well replicated, hypothesis-driven studies are: 1) needed, 2) now possible, and 3) essential to make best use of sequencing-based technologies to characterize the roles of microbial communities in the structure and function of diverse ecosystems. PMID- 30287355 TI - A comparison of the ability of the National Early Warning Score and the National Early Warning Score 2 to identify patients at risk of in-hospital mortality: A multi-centre database study. AB - AIMS: To compare the ability of the National Early Warning Score (NEWS) and the National Early Warning Score 2 (NEWS2) to identify patients at risk of in hospital mortality and other adverse outcomes. METHODS: We undertook a multi centre retrospective observational study at five acute hospitals from two UK NHS Trusts. Data were obtained from completed adult admissions who were not fit enough to be discharged alive on the day of admission. Diagnostic coding and oxygen prescriptions were used to identify patients with type II respiratory failure (T2RF). The primary outcome was in-hospital mortality within 24 h of a vital signs observation. Secondary outcomes included unanticipated intensive care unit admission or cardiac arrest within 24 h of a vital signs observation. Discrimination was assessed using the c-statistic. RESULTS: Among 251,266 adult admissions, 48,898 were identified to be at risk of T2RF by diagnostic coding. In this group, NEWS2 showed statistically significant lower discrimination (c statistic, 95% CI) for identifying in-hospital mortality within 24 h (0.860, 0.857-0.864) than NEWS (0.881, 0.878-0.884). For 1394 admissions with documented T2RF, discrimination was similar for both systems: NEWS2 (0.841, 0.827-0.855), NEWS (0.862, 0.848-0.875). For all secondary endpoints, NEWS2 showed no improvements in discrimination. CONCLUSIONS: NEWS2 modifications to NEWS do not improve discrimination of adverse outcomes in patients with documented T2RF and decrease discrimination in patients at risk of T2RF. Further evaluation of the relationship between SpO2 values, oxygen therapy and risk should be investigated further before wide-scale adoption of NEWS2. PMID- 30287356 TI - Donor IL-6 deficiency evidently reduces memory T cell responses in sensitized transplant recipients. AB - BACKGROUND: Resistance of tolerance induction in sensitized transplantation is mainly caused by generation of memory T cells. It is unknown whether alteration of graft niche such as level of pro-inflammatory cytokines can affect generation of memory T cells. METHODS: IL-6 deficient or wild-type (WT) C57BL/6 heart grafts were transplanted into pre-sensitized wild-type BALB/c recipients. Frequencies of memory T cells in the peripheral blood, grafts, and spleen were evaluated. RESULTS: We revealed that deficiency of donor IL-6 could significant prolong sensitized allograft survival. Compared with counterpart of WT group, frequency of effector memory CD4 + T cells (CD4 + CD44 + CD62L-) in the peripheral blood was significantly lower in the IL-6 KO group (p = .026) at day 3 post transplantation. Frequency of effector memory CD8 + T cells (CD8 + CD44 + CD62L-) in the peripheral blood was significantly lower in the IL-6 KO group (p < .0001) at day 3 post-transplant in comparison to that of WT group. No significant difference of central memory T cells was found between these groups. Histology demonstrated that deficiency of donor pro-inflammatory cytokine IL-6 (IL-6 KO group) preserved cardiac architecture with a mild infiltration of lymphocytes, whereas wild-type donor (control group) caused an evident lymphocytic infiltration within myocardial fibers of grafts and destruction of cardiac structure. CONCLUSION: Deficiency of pro-inflammatory IL-6 of donor graft could effectively prolong sensitized allograft survival, which was caused by a remarkable decrease of peripheral memory T cells rather than central memory T cells. This unveiled mechanism of targeting IL-6 signaling pathway might provide a novel insight into preventing allograft rejection for sensitized transplant recipients.

AB - This study is to characterize mechanical properties of uniaxial tension and stress relaxation responses of muscle tissues of tongue and soft palate. Uniaxial tension test and stress relaxation test on 39 fresh tissue samples from four five month-old boars (65 +/- 15 kg) are conducted. Firstly, the rationality of the samples' dimension design and experimenal data measurement is validated by one way ANOVA F-type test. Mechanical properties, including stress-strain relationship and stress relaxation characteristic, are then investigated in details to show the nonlinear behaviors of the tissue samples clearly. Finally, a constitutive model of representing the mechanical properties is formulated within the nonlinear integral representation framework proposed by Pinkin and Rogers, and corresponding material parameters are fitted to the experimental data based on the Levenberg-Marquardt minimization algorithm. The results of the fitting comparison prove that the formulated constitutive model can capture the observed nonlinear behaviors of the muscle tissue samples in both the axial tension and stress relaxation experiments.

AB - PURPOSE: We investigated the feasibility and accuracy of using carbon fiducials to localize the lumpectomy cavity with 2-dimensional kV imaging for early stage breast cancer radiation therapy. METHODS AND MATERIALS: Carbon fiducials were placed intraoperatively in the periphery of the lumpectomy cavity. Nine patients received whole breast irradiation with a boost, and 2 patients received 3 dimensional conformal partial breast irradiation. A total of 89 fractions were assessed for setup errors relative to a predefined gold standard, cone beam computed tomography (CBCT) match to the lumpectomy cavity, using the following 4 setup methods: (1) Align skin tattoos with lasers; (2) match bone with 2 dimensional-2-dimensional (2D/2D) kV onboard imaging (OBI); (3) match the whole breast with CBCT; and (4) match carbon fiducials with 2D/2D kV OBI. The margin for the planning target volume (PTV) was calculated by 2 standard deviations of the setup errors, and compared among the 4 setup methods. Setup errors for patients treated with free breathing and patients with deep inspiration breath hold were also compared. RESULTS: The carbon fiducials were sufficiently visible on OBI for matching and introduced minimal artifacts. Of the 4 alignment methods, 2D/2D OBI match to fiducials resulted in the smallest setup errors. The PTV margin was 12 mm for aligning skin tattoos using lasers, 9.2 mm for matching bone on OBI, 6.5 mm for matching breast on CBCT, and 3.5 mm for matching fiducials on 2D/2D OBI. Compared with free breathing, deep inspiration breath hold generally reduced the standard deviations of the setup errors, but further investigation would be needed. CONCLUSIONS: Matching to carbon fiducials increased the localization accuracy to the lumpectomy cavity. This reduces residual setup error and PTV margins, facilitating tissue sparing without diminishing treatment efficacy.

AB - The aim of this study was to prepare hydroxypropyl-methyl cellulose (HPMC)-K15 based hydrogels via free radical polymerization using 2-acrylamido-2-methyl propane sulphonic acid (AMPS) as a monomer and N,N'-methylene bisacrylamide (MBAAm) as a crosslinker. Loxoprofen sodium was chosen as a model drug and successfully loaded in hydrogel discs. Sol-gel, porosity, loading efficiency, and the in vitro drug release analysis were carried out to evaluate its drug delivery potential. HMPC-g-poly(AMPS) hydrogels were characterized by using Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and scanning electron microscopy (SEM) approaches. Maximum swelling and drug release were observed at pH 7.4. Kinetic modelling suggested that drug release followed first-order kinetics with the non-Fickian mechanism. FTIR and DSC confirmed the formation of new hydrogels. SEM micrographs confirmed uneven, rough, and partially porous type of surface. These results suggested that HMPC-g poly(AMPS) hydrogels can be a prospective pH-responsive carrier for delivery of water-soluble drugs, such as loxoprofen sodium.

AB - In this study, the structural characterization and physicochemical properties of starches from seven purple sweet potato varieties (Fuzi No. 1, Guang No. 161, Jihei No. 1, Ningzi No. 1, Ningzi No. 2, Xuzi No. 6 and Xuzi No. 8) cultivated in China were compared. Starch granules of purple sweet potatoes all exhibited round, polygonal and hemispherical shapes with granule sizes ranging from 4.3 to 23.6 MUm. X-ray powder diffraction patterns and 13C nuclear magnetic resonance spectra revealed purple sweet potato starches were CA-type with relative crystallinity varying from 34.0% to 37.3%. Small-angle X-ray scattering spectra indicated the lamellar repeat distances of starch granules were in the range of 9.962-10.137 nm. Ratios of 1045/1022 cm-1 and 1022/995 cm-1 of Fourier transform infrared spectra varied in the range of 0.689-0.887 and 0.850-0.974, respectively. Amylose contents of purple sweet potato starches differed from 18.2 to 27.2%. Purple sweet potato starches exhibited different gelatinization properties but similar thermal stability. Moreover, resistant starch contents varied from 29.25% to 43.50%. Our study indicated the granule size, relative crystallinity, the degree of short-range order, amylose content, gelatinization property and in vitro digestibility of purple sweet potato starches were greatly influenced by the variety of purple sweet potato. PMID- 30287361 TI - Hyaluronic acid, a promising skin rejuvenating biomedicine: A review of recent updates and pre-clinical and clinical investigations on cosmetic and nutricosmetic effects. AB - Hyaluronic acid (HA) plays multifaceted role in regulating the various biological processes such as skin repairmen, diagnosis of cancer, wound healing, tissue regeneration, anti-inflammatory, and immunomodulation. Owing to its remarkable biomedical and tissue regeneration potential, HA has been numerously employed as one of the imperative components of the cosmetic and nutricosmetic products. The present review aims to summarize and critically appraise recent developments and clinical investigations on cosmetic and nutricosmetic efficacy of HA for skin rejuvenation. A thorough analysis of the literature revealed that HA based formulations (i.e., gels, creams, intra-dermal filler injections, dermal fillers, facial fillers, autologous fat gels, lotion, serum, and implants, etc.) exhibit remarkable anti-wrinkle, anti-nasolabial fold, anti-aging, space-filling, and face rejuvenating properties. This has been achieved via soft tissue augmentation, improved skin hydration, collagen and elastin stimulation, and face volume restoration. HA, alone or in combination with lidocaine and other co agents, showed promising efficacy in skin tightness and elasticity, face rejuvenation, improving aesthetic scores, reducing the wrinkle scars, longevity, and tear trough rejuvenation. Our critical analysis evidenced that application/administration of HA exhibits outstanding nutricosmetic efficacy and thus is warranted to be used as a prime component of cosmetic products. PMID- 30287362 TI - Modified nickel ferrite nanocomposite/functionalized chitosan as a novel adsorbent for the removal of acidic dyes. AB - As a new type of magnetic adsorbent, a nickel ferrite nanocomposite modified by functionalized chitosan was developed to remove methyl orange and Congo red from aqueous solutions. This new adsorbent was characterized and utilizing batch adsorption approach, the mechanism of methyl orange and Congo red removal were probed. Following that the study on pertinent parameters which could influence the efficiency of the dyes removal, i.e. pH of the solution, initial dye concentration, dose of the adsorbent, and contact time were accomplished in order to arrive their optimized values by using response surface methodology. In addition, kinetics and isotherm studies were conducted on the developed system. Langmuir model was used to probe adsorption isotherm, acquiring adsorption capacity of 551.2 and 274.7 mg g-1 for methyl orange and Congo red, respectively. Both of methyl orange and Congo red adsorption kinetics obeyed a pseudo-second order kinetic model, indicating that adsorption was the rate-limiting step and only 5 min was required to remove 50% of dyes. The fitting of experimental data was fulfilled with intra-particle diffusion reaching to conclusion that the adsorption kinetic could be controlled simultaneously by film diffusion and intra particle diffusion. Furthermore, the desorption studies of dyes showed that the adsorbent is reusable. PMID- 30287363 TI - Extraction, preliminary characterization and in vitro antioxidant activity of polysaccharides from Oudemansiella radicata mushroom. AB - Oudemansiella radicata mushroom has many functions. Optimal condition of extracting its polysaccharides (ORP) with a yield of 5.85 +/- 0.13% were determined by using RSM: extraction temperature 84 degrees C, extraction time 2.3 h and ratio of water to raw material 20.0 mL/g. ORP-1, ORP-2 and ORP-3 were further obtained by chromatography with an average molecular of 13,921 Da, 14,942 Da and 10,209 Da, respectively. ORP-1 is mainly composed of mannose, ribose, glucose, galactose and xylose in a ratio of 2.46:2.63:3.89:3.22:2.78; ORP-2 is mainly composed of ribose, glucose and xylose in a ratio of 2.63:3.38:2.65; ORP-3 is mainly composed of glucose, xylose in a ratio of 3.38: 2.65. ORP exhibits relatively strong in vitro antioxidant activity. Except crude ORP, ORP-1 has the highest DPPH and ABTS radical scavenging activity, and ORP-3 shows the strongest hydroxyl radical scavenging activity and ferrous ion chelating activity, while the three fractions have no significance in scavenging radical superoxide anion. PMID- 30287364 TI - RK, the first scorpion peptide with dual disintegrin activity on alpha1beta1 and alphavbeta3 integrins. AB - Scorpion peptides are well known for their pharmaceutical potential on different targets. These include mainly the ion channels which were found to be highly expressed in many diseases, including cancer, auto-immune pathologies and Alzheimer. So far, however, the disintegrin activity had only been characterized for snake venom molecules. Herein, we present the first short peptide, purified from the venom of Buthus occitanus tunetanus, (termed RK) able to inhibit the cell adhesion of Glioblastoma, Melanoma and Rat pheochromocytoma to different extracellular matrix (ECM) receptors. Anti-integrin antibody assay suggests that RK interacts with both alpha1beta1 and alphavbeta3 with a more pronounced effect for the former. The examination of the primary structure of RK suggests the involvement of two motifs: KSS, analogue to KTS which was characterized for alpha1beta1 Snake venom disintegrins, and ECD, analogue to RGD which was found to be active on alphavbeta3. To assess their roles in the disintegrin activity of RK, we conducted a computational analysis. The molecular docking study shows that RK involves mainly two segments to interact with the alpha1beta1 integrin, but the peptide does not implicate the KSS motif in the interaction. The molecular modeling study, suggests the key contribution of the ECD segment in the interaction with alphavbeta3 integrin. PMID- 30287365 TI - Preparation and characterization of WS2 decorated and immobilized on chitosan and polycaprolactone as biodegradable polymers nanofibers: Photocatalysis study and antibiotic-conjugated for antibacterial evaluation. AB - In the present work, WS2 nanoparticles and immobilized on chitosan and polycaprolactone as biodegradable polymers as photocatalyst were developed and studied for photocatalytic degradation of representative Neomycin as an aminoglycoside antibiotic. The WS2 nanoparticles were synthesized using the hydrothermal method. Further, the photocatalyst were characterized by different analytical instruments energy dispersive X-ray spectrometer (EDS), scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis, and UV-Vis absorption spectroscopy, in order to understand their physical and optical properties. The mean crystallite sizes of WS2 nanoparticles, WS2/chitosan nanofibers and WS2/polycaprolactone nanofibers were 80.00, 70.14 and 68.71 nm, respectively. The optical absorption study revealed the presence of direct band to-band transition with band-gap ranging from 2.0 to 1.8 eV for WS2, WS2/chitosan nanofibers and WS2/polycaprolactone nanofibers, respectively. The photocatalytic activity of the three photocatalyst was tested by UV-light-induced degradation of Neomycin antibiotic. The WS2/chitosan nanofibers and WS2/polycaprolactone nanofibers photocatalyst showed high amount of photodegradation in comparison to WS2 nanoparticles. The optimum degradation using WS2, WS2/chitosan nanofibers and WS2/polycaprolactone nanofibers occurred under UV light at pH:7 in 40 min. The bactericidal test was determined under light illumination (visible source light) and that the neomycin conjugated WS2/chitosan nanofibers and WS2/polycaprolactone nanofibers demonstrated good efficiency in antibacterial efficiency compared to pure WS2/chitosan nanofibers and WS2/polycaprolactone nanofibers. PMID- 30287366 TI - Semi-interpenetrating hydrogels from carboxymethyl guar gum and gelatin for ciprofloxacin sustained release. AB - The present work reports the synthesis of new generation semi-interpenetrating (s IPN) hydrogels from carboxymethyl guar gum (CMGG) and gelatin with enhanced gel properties for suitable drug delivery applications. Hydrogels are three dimensional polymer networks which respond to water and ion interactions. Irreversible s-IPN hydrogels were prepared by CMGG interactions in gelatin and characterized in FT-IR, SEM and thermal studies. CMGG was synthesized by Hofmeister ion guided homogeneous phase reactions. The swelling kinetics of the newer s-IPN hydrogels followed Schott's pseudo second order model. Furthermore, the hydrogels were hemocompatible, non-cytotoxic and appropriate for applications in physiological environment. Model drug ciprofloxacin was loaded within the hydrogels and the drug release was found to be a combination of both diffusion and hydrogel degradation. New generation s-IPN biopolymer hydrogels of carboxymethyl guar gum and gelatin holds promise for its application as sustained drug delivery device or alternatively as hydrogel sorbents for bio-toxins and molecules of biomedical importance. PMID- 30287367 TI - Effects of temperature, starch concentration, and plasticizer concentration on the physical properties of ulluco (Ullucus tuberosus Caldas)-based edible films. AB - Ulluco starch could be a promising renewable source for the production of biodegradable or edible films, as an alternative to plastic. This would mitigate the negative impact of plastics on the environment. The aim of this work was to study the effect of the starch concentration (SC), glycerol concentration (GC), and drying temperature (T) of ulluco starch-based films on their physical properties using stepwise regression (SR) and artificial neural network (ANN) approaches. The physical properties, such as the solubility (S), water vapour permeability (WVP), tensile strength (TS), elongation at break (EB), and transparency, of the edible films were satisfactory. The feed-forward and cascade forward neural networks satisfactorily modelled the effect of the SC, GC, and T on the mechanical, optical, and water-affinity properties (WAP) of the edible films. ANN approach showed better results than SR in all the properties and ANN models were used in the sensitivity analysis and optimization. The global sensitivity analysis showed that the GC had the greatest influence on the physical properties. A desirability function-based optimization including WVP, EB and OP showed comparable values between experimental and estimated data. Based on the results of this study, the use of ulluco starch for the preparation of edible films has enormous potential for the replacement of non-biodegradable plastic packaging. PMID- 30287368 TI - Physicochemical analysis, structural elucidation and bioactivities of a high molecular-weight polysaccharide from Phellinus igniarius mycelia. AB - Phellinus igniarius is a well-known edible and medicinal fungus consumed in Asia for centuries. In the present study, a polysaccharide named PIP-1 was obtained from Phellinus igniarius mycelia, its physicochemical properties were determined, its detailed structures were elucidated by analysis of its depolymerized product, and its antioxidant and antitumor activities were evaluated. Results showed that PIP-1 had a high molecular weight, a high intrinsic viscosity and a linear repeating backbone composed of glucopyranose (Glcp), galactopyranose, and mannopyranose joined by alpha-(1 -> 4), alpha-(1 -> 3), and alpha-(1 -> 6) linkages, and single alpha-terminal-D-Glcp as side chains 6-O-linked to the main chain according to the GC-MS and NMR results, and exhibited triple helical structure. Pharmacological results revealed that PIP-1 could effectively scavenge hydroxyl radicals, partly scavenge DPPH radials and chelate ferrous metal ions. Furthermore, PIP-1 showed potent inhibitory effects on growth of HT-29 and MCF-7 cells. These findings suggested that high-molecular-weight PIP-1 containing triple helical structure and only alpha-type glycosidic bond holds promise as novel functional foods and agents to promote human health. PMID- 30287369 TI - Reactive oxygen species generation and human serum albumin damage induced by the combined effects of ultrasonic irradiation and brilliant cresyl blue. AB - In this paper, brilliant cresyl blue (BCB) was selected as a sonosensitizer. The sonodynamic damage to human serum albumin (HSA) in the presence of BCB and the mechanism were studied by means of fluorescence and absorption spectra. Firstly, BCB could quench the intrinsic fluorescence of HSA obviously and the quenching mechanism was static quenching due to the formation of HSA-BCB complex. The results of the displacement experiments and the molecular modeling suggested that the binding site of BCB on HSA was site I, and hydrophobic forces and hydrogen bonds played major roles in the interaction between HSA and BCB. Secondly, the damage of HSA induced by the combined effects of ultrasonic irradiation and BCB was more efficient than that only BCB or ultrasound irradiation, which confirmed that BCB had sonodynamic activity. The damage degree of HSA was positively correlated with reactive oxygen species (ROS) produced in the system, which indicated that ultrasound could activate BCB to produce ROS, and the kinds of ROS produced by the combined effects of ultrasonic irradiation and BCB were mainly hydroxyl free radical, singlet oxygen and superoxide anion radical. PMID- 30287370 TI - A biotechnological approach to immunotherapy: Antivenom against Crotalus durissus cascavella snake venom produced from biodegradable nanoparticles. AB - Snakebite envenoming is a tropical disease neglected worldwide. In Brazil, the Crotalus durissus cascavella (CDC) snake belongs to a genus with venom of highest lethality. A search for new immunoadjuvants aimed to expand the therapeutic alternatives to improve vaccines and antivenom. This approach proposed to produce small and narrow-sized cationic CDC venom-loaded chitosan nanoparticles (CHNP) able to induce antibody response against the CDC venom. The ionic gelation method induced the formation of stable and slightly smooth spherical nanoparticles (<160 nm) with protein loading efficiency superior to 90%. The interactions between venom proteins and CHNP assessed using FT-IR spectroscopy corroborated with the in vitro release behavior of proteins from nanoparticles. Finally, the immunization animal model using BALB/c mice demonstrated the higher effectiveness of CDC venom-loaded CHNP compared to aluminum hydroxide, a conventional immunoadjuvant. Thus, CHNPs loaded with CDC venom exhibited a promising biotechnological approach to immunotherapy. PMID- 30287371 TI - Binding of anticancer drug daunomycin to parallel G-quadruplex DNA [d-(TTGGGGT)]4 leads to thermal stabilization: A multispectroscopic investigation. AB - Guanine rich DNA sequences form four stranded G-quadruplex structures found in telomeric DNA and oncogene promoters. Small molecules binding and stabilizing the G-quadruplex disrupt telomere maintenance and gene regulation, thereby limiting the proliferation of cancer cells. The anti-cancer drug daunomycin binds to both G-quadruplex DNA and duplex DNA. We have undertaken a study of interaction of daunomycin to [d-(TTGGGGT)]4 comprising telomeric DNA sequence from Tetrahymena thermophilia to understand the mechanisms of its action. Absorbance, fluorescence and circular dicroism spectra show significant change on interaction with no change in wavelength maxima. The daunomycin dimers present in free state in solution are disrupted on binding. Presence of all sequential short inter proton distance contacts in nuclear magnetic resonance spectra confirm external binding. The observed inter molecular nuclear Overhauser enhancements, changes in chemical shift and molecular docking studies establish well defined binding of daunomycin at two different sites of G-quadruplex DNA. Thermal stabilization of [d (TTGGGGT)]4 by 10-15 degrees C upon daunomycin binding is expected to reduce access of telomerase to its functional site at telomeres. The present studies on mode of action pave the way for alternate derivatives/analogues by chemical modification of anthracyclines to arrive at a more potent telomerase inhibitor. PMID- 30287372 TI - Molecular cloning and characterization of the novel CYP2J2 in dromedary camels (Camelus dromedarius). AB - Although its economic, cultural and biological importance, many genes haven't been depicted, sequenced or analyzed to date for Camelus dromedarius. In the present paper, the full-length c-DNA of a novel CYP2J2 (GenBank accession number MH511989) was cloned from liver, heart, and kidney mRNA by RACE-PCR. The full length c-DNA of the cloned CYP2J2 was sequenced and analyzed using bioinformatics methods. The full-length c-DNA sequence was 2135 bp with no introns. The open reading frame (ORF) had 1341 nucleotides which coded for a putative protein of 446 amino acids. The deduced protein is located in the endoplasmic reticulum. It has two transmembrane regions. The nucleotides and deduced amino acids sequences of the cloned CYP2J2 were 1400 nucleotides and 47 amino acids shorter than the predicted homolog respectively. This study is the first description of the putative CYP2J2 gene, which opens the way to a new investigation-so far-never accomplished in Camelus dromedarius. PMID- 30287374 TI - Increased expression of long non-coding RNA SNHG16 correlates with tumor progression and poor prognosis in non-small cell lung cancer. AB - In this study, we report that lncRNA SNHG16 is upregulated in non-small cell lung cancer (NSCLC) tissues, and correlates with tumor size, TNM stage and lymph node metastasis. Kaplan-Meier analysis shows that the patients with high SNHG16 expression have poorer disease-free survival (DFS) and overall survival (OS) than the patients with low SNHG16 expression. Multivariate Cox regression analysis reveals that SNHG16 expression could be regarded as an independent predictor for DFS and OS in NSCLC patients. Cell experiments show that SNHG16 promotes NSCLC cell proliferation, migration and invasion. miR-146a is further identified and confirmed to be the target of SNHG16, and SNHG16 functions by targeting miR-146a. Subsequently, MUC5AC, a major mucin in the human respiratory tract correlated with post-operative metastasis and recurrence of NSCLC, is confirmed to be regulated by SNHG16 and miR-146a, and plays a positive role in promoting cell proliferation, migration and invasion, which might be involved in the oncogenic activity of SNHG16-miR-146a axis in NSCLC. Animal experiments also confirm these conclusions. Collectively, these results elucidate a potential mechanism underlying the carcinogenesis role of SNHG16 in NSCLC, and indicate that SNHG16 could act as a novel promising marker for prognosis, and a potential therapeutic target for NSCLC treatment. PMID- 30287373 TI - Incorporation of magnetic NaX zeolite/DOX into the PLA/chitosan nanofibers for sustained release of doxorubicin against carcinoma cells death in vitro. AB - In the present study, the magnetic NaX nanozeolites were synthesized via microwave heating method and loaded into the PLA/chitosan solution. Doxorubicin (DOX) as an anticancer drug was simultaneously incorporated into the PLA/chitosan solution and the electrospinning process was used to fabricate the PLA/chitosan/NaX/Fe3O4/DOX nanofibers for sustained release of DOX against carcinoma cells death. The synthesized nanozeolites were characterized using X ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and energy dispersive X-ray spectroscopy (EDX) analysis. The scanning electron microscopy (SEM) was used to determine the morphology and fiber diameter distribution of synthesized nanofibers. The DOX loading efficiency and in vitro DOX release profiles from nanofibers were investigated. The kinetic models including zero-order, Higuchi and Korsmeyer-Peppas were used to analyze the release mechanism of DOX from nanofibers. The effect of ferrite nanoparticles on the DOX release from chitosan/PLA/NaX/DOX and chitosan/PLA/NaX/Fe3O4/DOX nanofibers have been investigated in the presence of magnetic field and without magnetic field. The antitumor activity of synthesized nanofibers was also investigated on the carcinoma cells death. The maximum killing percentage of H1355 cells was found to be 82% using DOX loaded chitosan/PLA/NaX/ferrite in the presence of external magnetic field after 7 days of treatment.

AB - The mitochondrial (mt) genome of the black fly Simulium (Byssodon) maculatum, a pest of great importance for both humans and livestock, is sequenced and annotated for the first time. The genome structure, gene order and codon usage are typical among Diptera mt genomes. The mt genome is circular and 15,799 bp in length with 13 protein coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs) and a control region (CR), and with weakly positive AT-skew (0.02) and negative GC-skew (-0.12). Phylogenetic relationships of 16 species representing five families of Culicomorpha and two outgroups, based on mt genome data, were analyzed using both Maximum Likelihood and Bayesian methods. The monophyly of Culicomorpha is well supported, while Chironomoidea is indicated as a paraphyletic group. The well supported monophyletic Simuliidae is the sister group to Culicidae. PMID- 30287376 TI - Optimization of the preparation conditions of thermo-sensitive chitosan hydrogel in heterogeneous reaction using response surface methodology. AB - A thermo-sensitive hydroxybutyl chitosan (HBC) hydrogel was prepared by using 1,2 butene oxide as an etherification modifying agent. To obtain the maximum yield of HBC, response surface methodology (RSM) was applied to optimize its preparation conditions. Key factors were chosen firstly by Plackett-Burman design (PBD) experiments, such as the concentration of NaOH, the ratio of isopropanol to water and reaction temperature. Steepest ascent experiments were employed to reach the top region of the response and determine the appropriate levels of three key factors. A three-level-three-variable Box-Behnken design (BBD) was used to further optimize the synthesis parameters. The results indicated that when the concentration of NaOH and the ratio of isopropyl alcohol to water were 40.65% and 2.68:1 at reaction temperature of 59 degrees C, respectively, the yield of HBC production was 5.897 +/- 0.112 g and close to the predicted value (6.002 g), which demonstrated that the effectiveness of BBD model and the controllability for the yield of HBC in the heterogeneous reaction system. PMID- 30287377 TI - Synthesis of a bio-based polyurethane/chitosan composite foam using ricinoleic acid for the adsorption of Food Red 17 dye. AB - A novel bio-based polyurethane/chitosan foam (PU/chitosan) was synthesized using a polyol derived from castor oil and applied to remove Food Red 17 dye (FR17) from aqueous solutions. PU/chitosan foam presented better characteristics and adsorption potential than polyurethane foam (PU). PU/chitosan foam showed a semi crystalline structure, with several functional groups, high porosity and good mechanical properties. These characteristics are adequate for adsorptive separations. Using identical adsorption conditions, PU/chitosan was able to remove >98% of FR17 dye from the solution, while, PU removed only 40%. The adsorption of FR17 on PU/chitosan composite foam was favored at pH 2. Pseudo second order model was the most adequate to represent the kinetic data. The equilibrium data followed the Sips model, with a maximum adsorption capacity of 267.24 mg g-1. The adsorption process was spontaneous, favorable and endothermic. The results showed that polyurethane foams are capable to support chitosan, generating an adsorbent with better mechanical characteristics and high potential to remove anionic dyes from aqueous media. PMID- 30287378 TI - Solidification of liquid Modified Apple Polysaccharide by its adsorption on solid porous carriers through spray drying and evaluation of its potential as binding agent for tablets. AB - In the present study application of Modified Apple Polysaccharide (MAP) as tablet binder was evaluated. Liquid MAP was extracted from apple and solidified by adsorbing it on porous surface of Aerosil-200 and trehalose and this dispersion was dried using spray dryer. The concentration of excipients as well as spray drying conditions was optimised by using Box Behnken Design to achieve desirable powder characteristics. The optimised batch of solid MAP was characterized by DSC, PXRD, SEM, and FT-IR studies that confirmed complete adsorption of liquid MAP on the surface of Aerosil-200 and trehalose. This solid MAP was investigated for its binding efficacy for tablet formulation and its binding potential was compared with acacia and polyvinyl pyrrolidone K-30. Mesalamine (model drug) granules containing different concentration of binders were prepared by wet granulation. The granules were evaluated for micromeritic properties and results were found within the pharmacopoeial limits. The prepared tablets were subjected for post compression studies such as hardness, friability, disintegration, dissolution, physical stability, content uniformity and percentage elastic recovery and their results were found good. At 2.5% w/w concentration in tablet, the solid MAP has shown shorter disintegration time and faster dissolution profile as compared to other concentrations used including good physico mechanical properties. PMID- 30287379 TI - Relations between chain-length distribution, molecular size, and amylose content of rice starches. AB - Starch molecular structure, in terms of chain-length distribution (CLD) and molecular size, are important structural features regarding to "(starch) structure-property" relations for starch-based foods. In this study, amylopectin CLDs from fluorophore-assisted carbohydrate electrophoresis (FACE) are parameterized by a biosynthesis-based model, amylose CLDs and molecular sizes of amylose and amylopectin are measured by size-exclusion chromatography (SEC), and statistically meaningful relationships are established between starch CLDs, starch molecular size, and amylose content using rice starches with a wide range of amylose content. This shows that amylopectin molecular size is increased by increasing the proportion of short amylopectin chains with degree of polymerization (DP) 6-32 and decreasing the percentage of long amylopectin chains with DP 63-100. On the other hand, molecular sizes of both branched amylopectin and amylose molecules are negatively correlated with amylose content, suggesting that high-amylose rice tends to have smaller amylopectin and amylose molecular sizes. These relations are rationalized in terms of chain-length effects on the production of branched amylopectin and amylose molecules between different rice cultivars, which could provide new insights regarding to starch "structure property" relations. PMID- 30287380 TI - Glucose-sensitive delivery of metronidazole by using a photo-crosslinked chitosan hydrogel film to inhibit Porphyromonas gingivalis proliferation. AB - A novel glucose-sensitive drug delivery system with controlled release of metronidazole was synthesized by using biocompatible photo-crosslinked chitosan hydrogel film. Specifically, methacrylic anhydride, as photosensitive substance, was firstly grafted on chitosan molecular chains and then UV irradiation was applied as the crosslinking method. Glucose sensitivity was endowed by immobilizing glucose oxidase on the surface of chitosan film. The physicochemical characteristics including chemical composition, crosslinking degree, mechanical strength and related enzyme properties were investigated successively. Cytotoxicity test, drug release and anti-bacterial test were carried out, respectively. The results show that this photo-crosslinked hydrogel film has good mechanical properties; meanwhile, the immobilized enzyme's bonding capacity and activity can maintain a relatively high level after surface activation. In addition, this material possesses better biocompatibility than chemical crosslinked samples. What's more, it can sense the ambient glucose stimulus, rapidly and correspondingly adjust its inner pore structure to control the loaded metronidazole release, lead to an improved antimicrobial activity against Porphyromonas gingivalis under high glucose concentration. This glucose sensitive hydrogel film may provide a promising method for diabetic's periodontitis therapy in clinic.

AB - The strain RS20D capable of significantly improving yogurt texture was isolated from traditional fermented vegetable products, and identified as Lactobacillus plantarum RS20D. The total exopolysaccharides (EPS) were prepared from reconstituted skim milk fermentation by RS20D, and purified through DEAE Sepharose CL-6B and Sephadex G-100, and consequently the purified fraction designated as RS-r2 was obtained. The further work aimed to elucidate the structural features of RS-r2 via FT-IR spectrum, HPSEC and monosaccharide composition analysis was carried out. The results showed that RS-r2 was a novel acidic heteropolysaccharide mainly consisted of glucose, galactose and glucosamine in a molar ratio of 2.0:1.5:1. The molecular weight was estimated to be 1.69 * 106 Da. The EPS had a high degradation temperature (250 degrees C), suggesting its high thermal stability. SEM and AFM analysis of EPS further revealed chain microstructure anchored with many regular spherical shape in aqueous solution. In vitro test showed that total EPS secreted by RS20D could stimulate macrophage RAW264.7 to release NO significantly and up-regulated the gene expression of pro-inflammatory cytokines at the mRNA level. Current study suggested that RS20D could be a potential source of immunoregulatory polysaccharide and may be applied as a functional starter culture to improve yogurt texture in the dairy industry.

AB - The goal of this study is to reveal mechanism of preparing high quality modified starch by advanced equipment in well-known modified starch enterprises. Corn starch was used as raw material to prepare starch acetate with low degree of substitution under grinding, and the effect of grinding on the quality of starch acetate was studied. The effects of grinding on structures and properties of native corn starch were investigated. The mechanochemical theory was used to analyze the influence mechanism of grinding on quality of starch acetate. The results showed that the reaction efficiency (RE) of starch acetate increased from 70.98% to 85.80% at 4 h of grinding, and other qualities (solubility and swelling power) also increased. However, RE and other qualities of starch acetate were very different at 12 and 20-60 h of grinding. The changes of structures and properties of native starch after grinding showed that grinding has a significant mechanochemical effect on corn starch granules. The models of starch molecules and granules were made to reveal the "secret" of these advanced equipment in well known modified starch enterprises.

AB - CA 125 is a Mucin glycoprotein and its concentration in human serum correlates with a woman's risk of developing ovarian cancer and also indicates response to therapy in diagnosed patients. Accurate detection of this large, complex protein in patient biofluids is of great clinical relevance. In this work, an innovative immunoassay for quantitation of CA 125 based on signal amplification strategy was proposed. In this work, Horseradish peroxidase (HRP) labeled CA 125-antibody (anti-CA 125) was immobilized onto a green and biocompatible nanocomposite containing poly cetyl trimethyl ammonium bromide (P (CTAB) as conductive matrix, chitosan (CS) as biocompatible agent and sliver nanoparticles (Ag NPs) as signal amplification element. Therefore, a novel nanocomposite film based P (CTAB-CS) and Ag NPs was exploited to develop a highly sensitive immunosensor for detection of CA 125 protein. Importantly, Ag NPs prepared by electrodeposition method which lead to compact morphology. Fully electrochemical methodology was used to prepare a new transducer on a glassy carbon surface which provided a high surface area to immobilize a high amount of the anti-CA 125. The surface morphology of electrode was characterized by high-resolution field emission scanning electron microscope (FE-SEM) and energy dispersive spectroscopy (EDS). The immunosensor was employed for the detection of CA 125 using cyclic voltammetry (CV) and differential pulse voltammetry (DPVs) techniques. Under optimized condition the calibration curve for CA 125 concentration by SWV and DPV was linear in 0.01-400 U/mL with lower limit of quantification of 0.001 U/mL. The method was successfully applied assay of the CA 125 in unprocessed human plasma samples.

AB - Disrupted fear inhibition is a characteristic of many anxiety disorders. Investigations into the neural mechanisms responsible for inhibiting fear will improve understanding of the essential circuits involved, and facilitate development of treatments that promote their activity. Within the basolateral amygdala (BLA), Thy1-expressing neuron activity has been characterized by us and others as promoting fear inhibition to discrete fear cues by influencing consolidation of cued fear learning or cued fear extinction. Here, we evaluated how activating BLA Thy1-expressing neurons using DREADDs affected the consolidation, expression, reconsolidation, and extinction of contextual fear. Using an inhibitory avoidance paradigm, our present findings indicate a similar involvement of BLA Thy1-expressing neuron activity in the consolidation and extinction, but not expression, of fear. Importantly, our data also provide the first evidence for involvement of these neurons in inhibiting fear reconsolidation. Therefore, these data enhance our understanding of the roles that Thy1-expressing neurons within the BLA play in inhibiting fear when examining avoidance, in addition to the already established role in Pavlovian fear paradigms. Future investigations should further explore the circuits responsible for these contextual effects modulated by BLA Thy1 neuron activation, and could promulgate development of therapies targeting these neurons and their downstream effectors. PMID- 30287385 TI - Cog4 is required for protrusion and extension of the epithelium in the developing semicircular canals. AB - The semicircular canals in the inner ear sense angular acceleration. In zebrafish, the semicircular canals develop from epithelial projections that grow toward each other and fuse to form pillars. The growth of the epithelial projections is driven by the production and secretion of extracellular matrix components by the epithelium. The conserved oligomeric Golgi 4 protein, Cog4, functions in retrograde vesicle transport within the Golgi and mutations can lead to sensory neural hearing loss. In zebrafish cog4 mutants, the inner ear is smaller and the number of hair cells is reduced. Here, we show that formation of the pillars is delayed and that secretion of extracellular matrix components (ECM) is impaired in cog4-/- mutants. These results show that Cog4 is required for secretion of ECM molecules essential to drive the growth of the epithelial projections and thus regulates morphogenesis of the semicircular canals. PMID- 30287386 TI - Tailored disorder in calcite organization in tergite cuticle of the supralittoral isopod Tylos europaeus Arcangeli, 1938. AB - The crustacean cuticle forms skeletal elements consisting of chitin-protein fibrils reinforced by amorphous and crystalline calcium carbonate and phosphate minerals. The edges of skeletal elements are of particular interest. They are subject to repeated strain and stress because they form transitions to the arthrodial membranes connecting them. These allow for relative movements of skeletal elements. In this study, we investigate structure, chemical composition, mineral organization and local mechanical properties of the anterior and posterior edges of the tergite cuticle in the conglobating beach isopod Tylos europaeus and compare these with the protective dorsal region of the tergites. The distribution of mineral phases at the edges resembles that of dorsal regions of the tergites. At the transition with the unmineralized arthrodial membrane the calcite containing distal exocuticle is replaced by epicuticular material and the subjacent cuticular layers containing amorphous calcium carbonate become enriched with amorphous calcium phosphate. At the edges, the local elastic modulus and hardness values are significantly lower compared to dorsal regions of the tergite cuticle, for both, the calcite and the amorphous mineral containing layers. The calcite within the tergite cuticle is assembled in different texture patterns: (i) almost random co-orientation, (ii) almost single crystalline calcite, and (iii) a graded organization. Calcite organization and co-orientation strength is highly variable, not only on very few tens of micrometres, but also between regions with different skeletal functionality. Our results show that besides structure and composition, patterns of calcite organization contribute to the hierarchical architecture and functionality of biological composites. PMID- 30287387 TI - Crystal structure of a biliverdin-bound phycobiliprotein: Interdependence of oligomerization and chromophorylation. AB - Small, ultra-red fluorescence protein (smURFP) introduces the non-native biliverdin (BV) chromophore to phycobiliproteins (PBPs), allowing them to be used as transgenic labels for in vivo mammalian imaging. Presently, no structural information exists for PBPs bound to the non-native BV chromophore, which limits the further development of smURFP and related proteins as imaging labels or indicators. Here we describe the first crystal structure of a PBP bound to BV. The structures of smURFP-Y56R with BV and smURFP-Y56F without BV reveal unique oligomerization interfaces different from those in wild-type PBPs bound to native chromophores. Our structures suggest that the oligomerization interface affects the BV binding site, creating a link between oligomerization and chromophorylation that we confirmed through site-directed mutagenesis and that may help guide efforts to improve the notorious chromophorylation of smURFP and other PBPs engineered to bind BV. PMID- 30287388 TI - Tenascins in CNS lesions. AB - The tenascin family of glycoproteins comprises four members in vertebrates, of which tenascin-C (Tnc) and tenascin-R (Tnr) are particularly important in the context of lesions in the central nervous system (CNS). Tnc is expressed in the developing CNS, before it is down-regulated and mainly restricted to the adult neural stem cell niches. It regulates numerous processes including differentiation, adhesion, migration and neurite outgrowth. These aspects are critical in the developing organism, but also after damage. Interestingly, Tnc is indeed re-expressed in the injured CNS. Additionally, Tnc is an activator of the immune response, another important aspect after lesion. Tnr is part of perineuronal nets, a specialized form of extracellular matrix that enwraps subtypes of neurons and limits synaptic plasticity. We summarize the role of tenascins in the context of stem cell niches, barrier formation, synaptic plasticity and immune response in the damaged mammalian CNS. PMID- 30287389 TI - Enriched environment regulates thymocyte development and alleviates experimental autoimmune encephalomyelitis in mice. AB - Environmental and social factors have profound impacts on immune homeostasis. Our work on environmental enrichment (EE) has revealed a novel anti-obesity and anticancer phenotype associated with enhanced activity of CD8+ cytotoxic T lymphocytes in secondary lymphoid tissues. Here we investigated how an EE modulated thymus and thymocyte development. EE decreased thymus mass and cellularity, decreased the double positive thymocyte population, increased the proportion of CD8+ T cells, reduced the CD4:CD8 ratio, and downregulated CD69 expression in T cells. In a model of multiple sclerosis: experimental autoimmune encephalomyelitis (EAE), EE alleviated symptoms, inhibited spinal cord inflammation through regulation of type 1 T-helper cells mediated by glucocorticoid receptor signaling, and prevented EAE-induced thymic disturbance. Our mechanistic studies demonstrated that hypothalamic BDNF activated a hypothalamic-pituitary-adrenal axis mediating the EE's thymic effects. Our results indicate that a lifestyle intervention links the nervous, endocrine, and adaptive immune system, allowing the body to adapt to internal and external environments. PMID- 30287391 TI - Effect of dose and exposure protocol on the toxicokinetics and first-pass elimination of trichloroethylene and 1,1,1-trichloroethane. AB - Trichloroethylene (TCE) and 1,1,1-trichloroethane (TRI) are frequent contaminants of drinking water and of groundwater at hazardous waste sites. There is relatively little information on the target organ deposition of TRI, despite its ingestion and common occurrence in humans. An important aim of the study was to delineate and contrast the toxicokinetics (TK) and bioavailability (F) of TRI and its well metabolized congener, TCE. Blood profiles were obtained from male Sprague-Dawley rats given aqueous emulsions of 6 or 48 mg TRI/kg and 10 or 50 mg TCE/kg as an oral bolus (po) or by gastric infusion (gi) over 2 h. TCE exhibited nonlinear TK, with a disproportionate increase in AUC and decrease in clearance and F with increase in dose. TRI exhibited linear TK. F did not vary significantly with TRI dose or dosage regimen. F values were substantially higher for TRI than for the respective TCE groups. TRI was distributed widely to tissues of rats gavaged with 6 mg TRI/kg, with accumulation in fat. This experiment yielded tissue uptake and elimination profiles and in vivo tissue:blood partition coefficients (PCs). Finally, additional rats were given 10 mg/kg of TCE and TRI po, ia and iv, so that first-pass hepatic (FPh) and pulmonary (FPp) elimination could be measured directly. Total and FPh elimination of TCE exceeded that of TRI. TRI, with its higher air:blood PC, exhibited the higher FPp. TCE and TRI, despite several common physical and chemical properties resulting in similar absorption and systemic distribution, displayed dissimilar dosage and dose rate effects on their TK. PMID- 30287390 TI - Characteristics of Late Fatal Infections after Allogeneic Hematopoietic Cell Transplantation. AB - We analyzed late fatal infections (LFIs) in allogeneic stem cell transplantation (HCT) recipients reported to the Center for International Blood and Marrow Transplant Research. We analyzed the incidence, infection types, and risk factors contributing to LFI in 10,336 adult and 5088 pediatric subjects surviving for >=2 years after first HCT without relapse. Among 2245 adult and 377 pediatric patients who died, infections were a primary or contributory cause of death in 687 (31%) and 110 (29%), respectively. At 12 years post-HCT, the cumulative incidence of LFIs was 6.4% (95% confidence interval [CI], 5.8% to 7.0%) in adults, compared with 1.8% (95% CI, 1.4% to 2.3%) in pediatric subjects; P < .001). In adults, the 2 most significant risks for developing LFI were increasing age (20 to 39, 40 to 54, and >=55 years versus 18 to 19 years) with hazard ratios (HRs) of 3.12 (95% CI, 1.33 to 7.32), 3.86 (95% CI, 1.66 to 8.95), and 5.49 (95% CI, 2.32 to 12.99) and a history of chronic graft-versus-host disease GVHD (cGVHD) with ongoing immunosuppression at 2 years post-HCT compared with no history of GVHD with (HR, 3.87; 95% CI, 2.59 to 5.78). In pediatric subjects, the 3 most significant risks for developing LFI were a history of cGVHD with ongoing immunosuppression (HR, 9.49; 95% CI, 4.39 to 20.51) or without ongoing immunosuppression (HR, 2.7; 95% CI, 1.05 to 7.43) at 2 years post-HCT compared with no history of GVHD, diagnosis of inherited abnormalities of erythrocyte function compared with diagnosis of acute myelogenous leukemia (HR, 2.30; 95% CI, 1.19 to 4.42), and age >10 years (HR, 1.92; 95% CI, 1.15 to 3.2). This study emphasizes the importance of continued vigilance for late infections after HCT and institution of support strategies aimed at decreasing the risk of cGVHD. PMID- 30287392 TI - Mechanisms controlling the multistage post-translational processing of endogenous Nrf1alpha/TCF11 proteins to yield distinct isoforms within the coupled positive and negative feedback circuits. AB - To gain a better understanding of the multistep processing of Nrf1 to yield various isoforms with confused molecular masses, we herein establish a generally acceptable criterion required for identification of its endogenous full-length proteins and derivative isoforms expressed differentially in distinct experimental cell lines. Further work has been focused on the molecular mechanisms that dictate the successive post-translational modifications (i.e. glycosylation by OST, deglycosylation by NGLY, and ubiquitination by Hrd1) of this CNC-bZIP protein and its proteolytic processing to give rise to multiple proteoforms. Several lines of experimental evidence have demonstrated that the nascent Nrf1alpha/TCF11 polypeptide (non-glycosylated) is transiently translocated into the endoplasmic reticulum (ER), in which it becomes an inactive glycoprotein-A, and is folded in a proper topology within and around membranes. Thereafter, dynamic repositioning of the ER-resident domains in Nrf1 glycoprotein is driven by p97-fueled retrotranslocation into extra-ER compartments. Therein, Nrf1 glycoprotein is allowed for deglycosylation digestion by glycosidases into a deglycoprotein-B and its progressive proteolytic processing by cytosolic DDI-1/2 and proteasomes so as to generate N-terminally-truncated protein-C/D. This processing is accompanied by removal of a major N-terminal ~12.5-kDa polypeptide from Nrf1alpha. Interestingly, our present study has further unraveled that there exist coupled positive and negative feedback circuits between Nrf1 and cognate target genes, including those encoding its regulators p97, Hrd1, DDI-1 and proteasomes. These key players are differentially or even oppositely involved in diverse cellular signaling responses to distinct extents of ER-derived proteotoxic and oxidative stresses induced by different concentrations of proteasomal inhibitors.

PMID- 30287393 TI - Satisfaction, Salaries and Sustainability: Results of a National Survey of Pediatric Program Directors. AB - OBJECTIVES: Describe the career and work environment of pediatric program directors (PDs) and associated factors, including salary disparities and long term career plans. METHODS: A national, anonymous, electronic survey was sent to all categorical residency PD members of the Association of Pediatric Program Directors (APPD). Surveys assessed PD demographics, characteristics of the residency program and the PDs' positions (including salary), and measures of satisfaction. Chi-square and Fisher's exact test were used to analyze results. RESULTS: 149 PDs (74%) responded. Significantly more men earned $250,000 or more annually (26.9% versus 6.1% of women), and gender remained a significant independent predictor of salary after controlling for age, academic rank and subspecialty. Satisfaction was high for most measures, although 20% or more reported low satisfaction with pay (38.9%), administrative workload (32.1%), managing accreditation and ACGME expectations (31.9%), resources (27.9%), work/life balance (24.1%), and being valued by administration (20.0%). Only 34.3% saw the PD position as an end goal, and 29.5% stated they would be in their current position in 5 years. Satisfaction with the PD career, with faculty relationships, with resident performance, and with administrative workload were associated with plans to remain. CONCLUSIONS: Most Pediatric Program Directors did not view the position of PD as their long-term career goal, and many identified administrative duties and work/life balance contributing to significant dissatisfaction. Without changes to address these issues, PD turnover may be high, with potential negative implications for the success of training programs. PMID- 30287395 TI - 3D morphometric analysis of calcified cartilage properties using micro-computed tomography. AB - OBJECTIVE: Our aim is to establish methods for quantifying morphometric properties of calcified cartilage (CC) from micro-computed tomography (MUCT). Furthermore, we evaluated the feasibility of these methods in investigating relationships between osteoarthritis (OA), tidemark surface morphology and open subchondral channels (OSCCs). METHOD: Samples (n = 15) used in this study were harvested from human lateral tibial plateau (n = 8). Conventional roughness and parameters assessing local 3-dimensional (3D) surface variations were used to quantify the surface morphology of the CC. Subchondral channel properties (percentage, density, size) were also calculated. As a reference, histological sections were evaluated using Histopathological osteoarthritis grading (OARSI) and thickness of CC and subchondral bone (SCB) was quantified. RESULTS: OARSI grade correlated with a decrease in local 3D variations of the tidemark surface (amount of different surface patterns (rs = -0.600, P = 0.018), entropy of patterns (EP) (rs = -0.648, P = 0.018), homogeneity index (HI) (rs = 0.555, P = 0.032)) and tidemark roughness (TMR) (rs = -0.579, P = 0.024). Amount of different patterns (ADP) and EP associated with channel area fraction (CAF) (rp = 0.876, P < 0.0001; rp = 0.665, P = 0.007, respectively) and channel density (CD) (rp = 0.680, P = 0.011; rp = 0.582, P = 0.023, respectively). TMR was associated with CAF (rp = 0.926, P < 0.0001) and average channel size (rp = 0.574, P = 0.025). CC topography differed statistically significantly in early OA vs healthy samples. CONCLUSION: We introduced a MU-CT image method to quantify 3D CC topography and perforations through CC. CC topography was associated with OARSI grade and OSCC properties; this suggests that the established methods can detect topographical changes in tidemark and CC perforations associated with OA. PMID- 30287396 TI - A graphic user interface for the evaluation of knee osteoarthritis (GEKO): an open-source tool for histological grading. AB - OBJECTIVE: In osteoarthritis (OA) models, histology is commonly used to evaluate the severity of joint damage. Unfortunately, semi-quantitative histological grading systems include some level of subjectivity, and quantitative grading systems can be tedious to implement. The objective of this work is to introduce an open source, graphic user interface (GUI) for quantitative grading of knee OA. METHODS: Inspired by the 2010 OARSI histopathology recommendations for the rat, our laboratory has developed a GUI for the evaluation of knee OA, nicknamed GEKO. In this work, descriptions of the quantitative measures acquired by GEKO are presented and measured in 42 histological images from a rat knee OA model. Using these images, across-session and within-session reproducibility for individual graders is evaluated, and inter-grader reliability across different levels of OA severity is also assessed. RESULTS: GEKO allowed histological images to be quantitatively scored in less than 1 min per image. In addition, intra-class coefficients (ICCs) were largely above 0.8 for across-session reproducibility, within-session reproducibility, and inter-grader reliability. These data indicate GEKO aided in the reproducibility and repeatability of quantitative OA grading across graders and grading sessions. CONCLUSIONS: Our data demonstrate GEKO is a reliable and efficient method to calculate quantitative histological measures of knee OA in a rat model. GEKO reduced quantitative grading times relative to manual grading systems and allowed grader reproducibility and repeatability to be easily assessed within a grading session and across time. Moreover, GEKO is being provided as a free, open-source tool for the OA research community. PMID- 30287397 TI - A systematic review of the small molecule studies of osteoarthritis using nuclear magnetic resonance and mass spectroscopy. AB - OBJECTIVE: To perform a systematic review of the small molecule metabolism studies of osteoarthritis utilising nuclear magnetic resonance (NMR) or mass spectroscopy (MS) analysis (viz., metabolomics or metabonomics), thereby providing coherent conclusions and reference material for future study. METHOD: We applied PRISMA guidelines (PROSPERO 95068) with the following MESH terms: 1. "osteoarthritis" AND ("metabolic" OR "metabonomic" OR "metabolomic" OR "metabolism") 2. ("synovial fluid" OR "cartilage" OR "synovium" OR "serum" OR "plasma" OR "urine") AND ("NMR" or "Mass Spectroscopy"). Databases searched were "Medline" and "Embase". Studies were searched in English and excluded review articles not containing original research. Study outcomes were significant or notable metabolites, species (human or animal) and the Newcastle-Ottawa Score. RESULTS: In the 27 studies meeting the inclusion criteria, there was a shift towards anaerobic and fatty acid metabolism in OA disease, although whether this represents the inflammatory state remains unclear. Lipid structure and composition was altered within disease subclasses including phosphatidyl choline (PC) and the sphingomyelins. Macromolecular proteoglycan destruction was described, but the correlation to disease factors was not demonstrated. Collated results suggested arachidonate signalling pathways and androgen sex hormones as future metabolic pathways for investigation. CONCLUSION: Our meta-analysis demonstrates significant small molecule differences between sample types, between species (such as human and bovine), with potential OA biomarkers and targets for local or systemic therapies. Studies were limited by numbers and a lack of disease correlation. Future studies should use NMR and MS analysis to further investigate large population subgroups including inflammatory arthropathy, OA subclasses, age and joint differences. PMID- 30287399 TI - Hyperglycosylated hCG activates LH/hCG-receptor with lower activity than hCG. AB - While human chorionic gonadotropin (hCG) appears to have an essential role in early pregnancy, it is controversial whether the hyperglycosylated form of hCG (hCG-h), which is the major hCG isoform during the first 4-5 weeks of pregnancy, is able to activate LH/hCG receptor (LHCGR). To address this, we utilized different extensively characterized hCG and hCGbeta reference reagents, cell culture- and urine-derived hCG-h preparations, and an in vitro reporter system for LHCGR activation. The WHO hCG reference reagent (99/688) was found to activate LHCGR with an EC50-value of 3.3 +/- 0.6 pmol/L (n = 9). All three studied hCG-h preparations were also able to activate LHCGR, but with a lower potency (EC50-values between 7.1 +/- 0.5 and 14 +/- 3 pmol/L, n = 5-11, for all P < 0.05 as compared to the hCG reference). The activities of commercial urinary hCG (Pregnyl) and recombinant hCG (Ovitrelle) preparations were intermediate between those of the hCG reference and the hCG-h. These results strongly suggest that the hCG-h is functionally similar to hCG, although it has lower potency for LHCGR activation. Whether this explains the reduced proportion of hCG-h to hCG reported in patients developing early onset pre-eclampsia or those having early pregnancy loss remains to be determined. PMID- 30287398 TI - Social and neuromolecular phenotypes are programmed by prenatal exposures to endocrine-disrupting chemicals. AB - Exposures to endocrine-disrupting chemicals (EDCs) affect the development of hormone-sensitive neural circuits, the proper organization of which are necessary for the manifestation of appropriate adult social and sexual behaviors. We examined whether prenatal exposure to polychlorinated biphenyls (PCBs), a family of ubiquitous industrial contaminants detectable in virtually all humans and wildlife, caused changes in sexually-dimorphic social interactions and communications, and profiled the underlying neuromolecular phenotype. Rats were treated with a PCB commercial mixture, Aroclor 1221 (A1221), estradiol benzoate (EB) as a positive control for estrogenic effects of A1221, or the vehicle (4% DMSO), on embryonic day (E) 16 and 18. In adult F1 offspring, we first conducted tests of ultrasonic vocalization (USV) calls in a sociosexual context as a measure of motivated communications. Numbers of certain USV call types were significantly increased by prenatal treatment with A1221 in males, and decreased by EB in females. In a test of sociosexual preference for a hormone-vs. a non hormone-primed opposite sex conspecific, male (but not female) nose-touching with opposite-sex rats was significantly diminished by EDCs. Gene expression profiling was conducted in two brain regions that are part of the social decision-making network in the brain: the medial preoptic nucleus (MPN) and the ventromedial nucleus (VMN). In both regions, many more genes were affected by A1221 or EB in females than males. In female MPN, A1221 changed expression of steroid hormone receptor and neuropeptide genes (e.g., Ar, Esr1, Esr2, and Kiss1). In male MPN, only Per2 was affected by A1221. The VMN had a number of genes affected by EB compared to vehicle (females: Kiss1, Kiss1r, Pgr; males: Crh) but not A1221. These differences between EB and A1221 indicate that the mechanism of action of A1221 goes beyond estrogenic pathways. These data show sex-specific effects of prenatal PCBs on adult behaviors and the neuromolecular phenotype. PMID- 30287400 TI - A review on the mechanism of iodide metabolic dysfunction in differentiated thyroid cancer. AB - The incidence of differentiated thyroid cancer (DTC) has been increasing rapidly worldwide, and the risk factors remain unclear. With the growing number of patients with DTC, the related issues have been gradually highlighted. 131Iodide (131I) is an important treatment for DTC and has the potential to reduce the risk of recurrence. 131I is also an effective treatment for distant metastases of thyroid carcinoma. However, iodide metabolism dysfunction in metastatic foci causes patients to lose the opportunity of 131I treatment. This article reviews the related mechanisms of iodide metabolism dysfunction in DTC cells and summarizes the clinical transformation progression. PMID- 30287401 TI - Identification and comparative analysis of the miRNA expression profiles from four tissues of Micropterus salmoides using deep sequencing. AB - In the present study, four small RNA libraries were constructed from an M. salmoides population and sequenced using deep sequencing technology. A total of 9,888,822; 8,519,365; 20,566,198; and 15,762,254 raw reads representing 666,097; 755,711; 978,923; and 840,175 unique sequences were obtained from the spleen, liver, kidney, and muscle libraries, respectively. As a result, 509 known miRNAs belonging to 143 families and 1157 novel miRNAs were identified. The miRNAs displayed diverse expression levels among the four libraries, among which most of the known miRNAs were expressed at higher levels than the novel miRNAs. Furthermore, stem-loop qRT-PCR was applied to validate and profile the expression of the differentially expressed miRNAs in the four different tissues, which revealed that some miRNAs showed tissue specific expression. The identification of miRNAs in M. salmoides will provide new information and enhance our understanding of the functions of miRNAs in regulating biological processes. PMID- 30287402 TI - Pathogenicity, Phylogenetic relationship and NGS based identification and assembly of tumorigenic Agrobacterium radiabacter plasmidic and chromosomic reads isolated from Prunus duclcis. AB - Although many Agrobacterium radiobacter strains have already been identified, only a few genomes of strains belonging to genomovar G4 have been sequenced so far. In this study, we report the first virulent genome sequence of Agrobacterium radiobacter strain tun 183, which is highly virulent to almond specie. The genome size was estimated to be 5.53 Mb, with 57.9%GC content. In total, 6486 genes encoding proteins and 61 genes encoding RNAs were identified in this genome. Comparisons with the available sequenced genomes of genomovar G4 as well as with other A. sp. were conducted, revealing a hexapartite genome containing circular and linear chromosomes in addition to two accessory plasmids and a tumor inducing plasmid (pTi) in strain tun 183. The phylogenetic analysis of recA gene clearly showed the clustering of tun 183 strain within genomovar G4, supporting the monophyly within this genomovar. PMID- 30287403 TI - A powerful method to integrate genotype and gene expression data for dissecting the genetic architecture of a disease. AB - To decipher the genetic architecture of human disease, various types of omics data are generated. Two common omics data are genotypes and gene expression. Often genotype data for a large number of individuals and gene expression data for a few individuals are generated due to biological and technical reasons, leading to unequal sample sizes for different omics data. Unavailability of standard statistical procedure for integrating such datasets motivates us to propose a two-step multi-locus association method using latent variables. Our method is powerful than single/separate omics data analysis and it unravels comprehensively deep-seated signals through a single statistical model. Extensive simulation confirms that it is robust to various genetic models as its power increases with sample size and number of associated loci. It provides p-values very fast. Application to real dataset on psoriasis identifies 17 novel SNPs, functionally related to psoriasis-associated genes, at much smaller sample size than standard GWAS. PMID- 30287404 TI - Diabetic gut microbiota dysbiosis as an inflammaging and immunosenescence condition that fosters progression of retinopathy and nephropathy. AB - The increased prevalence of type 2 diabetes mellitus (T2DM) and life expectancy of diabetic patients fosters the worldwide prevalence of retinopathy and nephropathy, two major microvascular complications that have been difficult to treat with contemporary glucose-lowering medications. The gut microbiota (GM) has become a lively field research in the last years; there is a growing recognition that altered intestinal microbiota composition and function can directly impact the phenomenon of ageing and age-related disorders. In fact, human GM, envisaged as a potential source of novel therapeutics, strongly modulates host immunity and metabolism. It is now clear that gut dysbiosis and their products (e.g. p-cresyl sulfate, trimethylamine-N-oxide) dictate a secretory associated senescence phenotype and chronic low-grade inflammation, features shared in the physiological process of ageing ("inflammaging") as well as in T2DM ("metaflammation") and in its microvascular complications. This review provides an in-depth look on the crosstalk between GM, host immunity and metabolism. Further, it characterizes human GM signatures of elderly and T2DM patients. Finally, a comprehensive scrutiny of recent molecular findings (e.g. epigenetic changes) underlying causal relationships between GM dysbiosis and diabetic retinopathy/nephropathy complications is pinpointed, with the ultimate goal to unravel potential pathophysiological mechanisms that may be explored, in a near future, as personalized disease-modifying therapeutic approaches. PMID- 30287405 TI - TLR4 triggered complex inflammation in human pancreatic islets. AB - Type 2 Diabetes (T2D) is strongly associated with obesity and inflammation. Toll like receptor-4 (TLR-4) is the major pro-inflammatory pathway with its ligands and downstream products increased systemically in T2D and in at-risk individuals. Detailed mechanisms of the complex proinflammatory response in pancreatic islets remain unknown. In isolated human islets LPS induced IL-1beta, IL-6, IL-8 and TNF production in a TLR4-dependent manner and severely impaired beta-cell survival and function. IL-6 antagonism improved beta-cell function. IL-8, which was identified specifically in alpha-cells, initiated monocyte migration, a process fully blocked by IL-8 neutralization. The TLR4 response was potentiated in obese donors; with higher IL-1beta, IL-6 and IL-8 expression than in non-obese donors. TLR4 activation leads to a complex multi-cellular inflammatory response in human islets, which involves beta-cell failure, cytokine production and macrophage recruitment to islets. In obesity, the amplified TLR4 response may potentiate beta-cell damage and accelerate diabetes progression.

AB - INTRODUCTION: The authors' main purpose was to develop a detailed finite element model (FEM) of the human orbit and to validate it by analyzing its behavior under the stress of blunt traumas. MATERIALS AND METHODS: A pre-existing 3D FEM of a human head was modified and used in this study. Modifications took into account preliminary research carried out on PubMed database. Data from a CT scan of the head were computed with Mimics(r) software to re-create the skull geometry. The mesh production, the model's properties and the simulations of blunt orbital traumas were conducted on Hyperworks(r) software. RESULTS: The resulting 3D FEM was composed of 640 000 elements and was used to perform blunt trauma simulations on an intact orbit. A total of 27 tests were simulated. 15 tests were realized with a metallic cylinder impactor; 12 tests simulated a hit by a closed fist. In all the tests conducted (27/27), the orbital floor was fractured. Fracture patterns were similar to those found in real clinical situations according to the buckling and hydraulic theories of orbital floor fractures. DISCUSSION: The similitude between the fracture patterns produced on the model and those observed in vivo allows for a validation of the model. This model constitutes, at the authors knowledge, the most sophisticated one ever developed.

AB - : The domestic silkworm Bombyx mori was domesticated from wild silkworm B. mandarina about 5000 years ago. Long-term domestication and breeding selection have led to the weight of domestic silkworm cocoon being ten times greater than that of wild silkworm cocoon. However, we found that wild silkworm cocoon has significantly much more abundance of sericin proteins than domestic silkworm cocoon. Strikingly, we found that many protease inhibitors have been significantly down-regulated in domestic silkworm cocoon compared with its wild progenitor by using isobaric tag for relative and absolute quantitation (iTraq) approach. Both real-time qPCR experiment and transcriptome data in silk gland also verified these results. In addition, our data indicated that protease inhibitor activity of wild silkworm cocoon was stronger than that of domestic silkworm cocoon, implying that relatively up-regulated protease inhibitors in wild silkworm cocoon may play protection roles against microorganisms. Thus, these protease inhibitors up-regulated in wild silkworm cocoon may have potential values in sericulture and medical practice. SIGNIFICANCE: This study revealed that there is a big difference in abundance of sericin proteins in cocoon between domestic and wild silkworms. Strikingly, many protease inhibitors have been significantly down-regulated in domestic silkworm cocoon compared with its wild progenitor. This may be due to different environments where the two silkworms live. In addition, the results also implied that relatively up-regulated protease inhibitors in wild silkworm cocoon may play protection roles against microorganisms. Thus, these protease inhibitors may have potential values in sericulture and medical practice. PMID- 30287408 TI - Combined use of biocompatible nanoemulsions and solid microneedles to improve transport of a model NSAID across the skin: In vitro and in vivo studies. AB - This study aimed to investigate the potential of lecithin-based nanoemulsions costabilized by sucrose esters, with and without skin pretreatment with stainless steel microneedles, to improve delivery of aceclofenac, as a model drug, into/across the skin. The characterization revealed favorable droplet size (about 180 nm), narrow size distribution (<0.15), high surface charge (about -40 mV) and satisfying long-term stability (one year at 4 +/- 1 degrees C) of the formulation costabilized by sucrose palmitate, demonstrating a similar trend observed for the reference stabilized by widely used lecithin/polysorbate 80 combination. In vitro release/permeation testing and differential stripping on the porcine ear proved the superiority of the sucrose ester- over polysorbate based nanoemulsion. However, in vitro findings were not fully indicative of the in vivo performances - no significant differences were observed between investigated formulations in pharmacokinetic profile and total amount of aceclofenac deposited in the rat skin 24 h after dosing, simultaneously pointing to delayed aceclofenac delivery into the systemic circulation. In addition, the ratio of plasma concentrations of aceclofenac and its major metabolite in rats, diclofenac, was remarkably changed after topical application of tested nanoemulsions compared to intravenous administration of aceclofenac solution. Finally, skin pretreatment with microneedles improved aceclofenac delivery into/across the rat skin from tested formulations, resulting in 1.4-2.1-fold increased bioavailability and 1.2-1.7-fold enhanced level of aceclofenac retained in the skin, as measured 24 h after administration. Moreover, the plasma concentrations of aceclofenac 24 h after application of tested formulations (lecithin/sucrose palmitate vs. lecithin/polysorbate 80) combined with microneedles (173.37 +/- 40.50 ng/ml vs. 259.23 +/- 73.18 ng/ml) were significantly higher than those obtained through intact skin (105.69 +/- 19.53 ng/ml vs. 88.38 +/- 14.46 ng/ml). However, obtained results suggest that combination of microneedles and sucrose palmitate-costabilized nanoemulsion could be useful to attain higher skin concentration, while combination of microneedles with polysorbate 80-costabilized nanoemulsion could be a preferable option for enhancing drug delivery into the bloodstream. PMID- 30287409 TI - The effect of amorphous and crystal sodium warfarin and its content uniformity on bioequivalence of tablets. AB - Warfarin is intensively discussed in terms of generic substitution due to particular cases of bleeding, which are attributable to fluctuations in API content or the substitution of crystalline (WSC) for amorphous (WSA) warfarin. The aim of this study was to assess to what extent the in vitro release was affected by the form of API depending on the composition and technology. Bioequivalent tablets containing 5 mg of WSA or WSC prepared by wet granulation or direct compression were used. Furthermore, tablets of the same composition with WSC or WSA prepared by direct compression were evaluated. Raman spectroscopy was used to confirm the presence of WSA or WSC. The dissolution was more influenced by the technology than by the form of API but even tablets with dissimilar profiles were bioequivalent. This is probably due to the precipitation of WSA and WSC in the stomach on a poorly soluble acidic form, which subsequently dissolves in the neutral environment of the small intestine. Recrystallization was demonstrated in the in vitro assay at a pH of 1.2 and 4.5 using Raman spectroscopy and X-ray diffraction. In summary, the content uniformity appears to be the main factor affecting the safety of the treatment. PMID- 30287410 TI - Strategies to improve the prediction accuracy of hepatic intrinsic clearance of three antidiabetic drugs: Application of the extended clearance concept and consideration of the effect of albumin on CYP2C metabolism and OATP1B-mediated hepatic uptake. AB - The antidiabetic drugs glibenclamide, repaglinide, and nateglinide are well-known substrates for hepatic uptake transporters of the organic anion transporting polypeptide (OATP) family and metabolizing enzymes of the cytochrome P450 (CYP) 2C subfamily. The systemic exposure of these drugs varies substantially among individuals, impacted by genetic polymorphisms of transporters and metabolizing enzymes as well as drug-drug interactions. The use of the conventional in vitro in vivo extrapolation (IVIVE) method was found to underestimate their hepatic intrinsic clearance (CLint,all); the clinically observed CLint,all values were >=10-fold higher than the predicted values from in vitro data. In order to improve the accuracy in predicting CLint,all of these drugs, the following modifications were implemented; i) the extended clearance concept was applied during IVIVE processes, ii) albumin was added to metabolic assays using human liver microsomes (to minimize the impact of intrinsic inhibitors on kinetic parameters for CYP2C-mediated metabolism) and to hepatic uptake assays (to accommodate the enhanced hepatic uptake observed with albumin-bound drugs), and iii) differing rates of efflux and influx via diffusion were used. The IVIVE method with these modifications yielded the predicted CLint,all values from in vitro data in closer agreement with the CLint,all values observed in vivo; the fold differences between the predicted and observed CLint,all values reduced from 13-15 to 5.9-6.7. Our current approach offers an improvement in the prediction of CLint,all and further investigations are warranted to enhance the prediction accuracy of IVIVE. PMID- 30287411 TI - Non-specific symptoms in adult patients referred to a Lyme centre. AB - OBJECTIVES: There is controversy whether non-specific symptoms can be related to previous Lyme borreliosis (LB). Positive serology can be considered a proxy for previous or persistent LB. We assessed non-specific symptoms and serology in patients suspected of LB referred to a Lyme centre. METHODS: Included were adult patients who visited a Lyme centre between 2008 and 2014. Before medical consultation, serum samples were taken and questionnaires on non-specific symptoms completed. The prevalence of non-specific symptoms was calculated for patients with positive and negative IgG serology. Logistic regression was used to obtain odds ratios (ORs) with 95% confidence interval (CI) for an association between positive serology and non-specific symptoms. RESULTS: Of 1439 included patients, 31.6% (455/1439) had positive serology. The most common non-specific symptoms were severe fatigue (61.4%, 883/1439), sleep disturbances (54.8%, 789/1439) and stiffness of neck/back (52.6%, 757/1439). The prevalence of severe fatigue was 53.0% (241/455) in patients with positive serology vs. 65.2% (642/984) in patients with negative serology (OR = 0.74; 95% CI, 0.58-0.94). The prevalence of sleep disturbances was respectively 46.2% (210/455) vs. 58.8% (579/984) (OR = 0.73; 95% CI, 0.58-0.93). The prevalence of stiffness of neck/back was respectively 47.7% (217/455) vs. 54.9% (540/984) (OR = 0.85; 95% CI, 0.67-1.06). CONCLUSIONS: In patients referred to a Lyme centre, non-specific symptoms did not occur more frequently in patients with positive serology compared to patients with negative serology. Hence, a questionnaire on non specific symptoms cannot be used for identifying patients with possible post-LB symptoms in clinical practice. PMID- 30287412 TI - Impact of Antimicrobial Treatment Duration on Outcome of Staphylococcus aureus Bacteremia: A Cohort Study. AB - OBJECTIVES: We aimed to assess the outcome of Staphylococcus aureus bacteremia (SAB) according to factors associated with necessity for longer treatment in conjunction with the duration of treatment. METHODS: We prospectively collected the data of patients with SAB consecutively during 12-39 months from 11 hospitals. If multiple episodes of SAB occurred in one patient, only the first episode was enrolled. Factors associated with necessity for longer treatment were defined as follows: persistent bacteremia, metastatic infection, prosthesis, and endocarditis. If any of the factors were present, the case was defined as longer antibiotic treatment warranted (LW) group, those without any factors were defined as shorter antibiotic treatment sufficient (SS) group. Poor outcome was defined as composite of 90-day mortality or 30-day recurrence. Duration of antibiotic administration was classified as <14 or >=14 days in SS-group, and <28 or >=28 days in LW-group. RESULTS: Among 2098 cases, the outcome was analyzed in 1866 cases, of which 591 showed poor outcome. SS-group accounted for 964 cases and LW group for 852 cases. On multivariate analysis, age over 65 years, pneumonia, higher SOFA score, chronic liver diseases were risk factors for poor outcome. Administration of antibiotics less than the recommendation was associated with poor outcome, but this significance was observed only in the LW-group (adjusted odds ratio 1.68, 95% confidence interval 1.00-2.83, p=0.05). CONCLUSIONS: Inappropriately short antibiotic treatment was associated with poor outcome in the LW-group. Vigilant evaluation for risk factors to determine the duration of treatment may improve the outcome among patients with SAB. PMID- 30287413 TI - 'How to do it'-molecular investigation of a hospital outbreak. AB - BACKGROUND: Studying hospital outbreaks by using molecular tools, i.e. synthesizing the molecular epidemiology data to its appropriate clinical epidemiologic context, is crucial in order to identify infection source, infer transmission dynamics, appropriately allocate prevention resources and implement control measures. Whole-genome sequencing (WGS) of pathogens has become the reference standard, as it is becoming more accessible and affordable. Consequently, sequencing of the full pathogen genome via WGS and major progress in fit-for-purpose genomic data analysis tools and interpretation is revolutionizing the field of outbreak investigations in hospitals. Metagenomics is an additional evolving field that might become commonly used in the future for outbreak investigations. Nevertheless, practitioners are frequently limited in terms of WGS or metagenomics, especially for local outbreak analyses, as a result of costs or logistical considerations, reduced or lack of locally available resources and/or expertise. As a result, traditional approaches, including pulsed field gel electrophoresis, repetitive-element palindromic PCR and multilocus sequence typing, along with other typing methods, are still widely used. AIMS: To provide practitioners with evidenced-based action plans for usage of the various typing techniques in order to investigate the molecular epidemiology of nosocomial outbreaks, of clinically significant pathogens in acute-care hospitals. SOURCES: PubMed search with relevant keywords along with personal collection of relevant publications. CONTENT: Representative case scenarios and critical review of the relevant scientific literature. IMPLICATIONS: The review provides practical action plans to manage molecular epidemiologic investigations of outbreaks caused by clinically significant nosocomial pathogens, while prioritizing the use and timely integration of the various methodologies. PMID- 30287414 TI - Identification of Neisseria meningitidis by MALDI-TOF MS may not be reliable. AB - OBJECTIVES: The matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) technique is increasingly used in hospital laboratories for routine identification of microorganisms. However, its performance is variable, particularly for highly variable species such as Neisseria meningitidis. Reliable identification of N. meningitidis is crucial for the management of invasive meningococcal disease by rapid implementation of treatment and preventive measures among close contacts. We assessed and improved N. meningitidis identification by MALDI-TOF MS by enriching the databases with reference strains identified using whole genome sequencing (WGS) as a reference standard. METHODS: We first built a collection of 24 strains from several species of the Neisseria genus that we characterized by WGS. This collection was added to the available database to test by MALDI-TOF MS another collection of 32 clinical isolates received between 2015 and 2017 at the French National Reference Laboratory for Meningococci. RESULTS: Using the commercially available library of mass spectrometry profiles, only 67% (95% confidence interval (CI), 47-82) concordance was observed at the species level between MALDI-TOF MS and WGS characterization. However, when the new enriched reference collection was used on the second subset of isolates, the identification of N. meningitidis was significantly improved (p 0.0016), showing 92% (95% CI, 75-98) specificity while that of the manufacturer's database alone was 52% (95% CI, 34-70). CONCLUSIONS: Our data highlight the need to update the available MALDI-TOF MS database with high-quality references to enhance the identification of N. meningitidis and avoid unwarranted preventive measures or missing identification. PMID- 30287415 TI - Interaction and Engagement with an Anxiety Management App: Analysis Using Large Scale Behavioral Data. AB - BACKGROUND: SAM (Self-help for Anxiety Management) is a mobile phone app that provides self-help for anxiety management. Launched in 2013, the app has achieved over one million downloads on the iOS and Android platform app stores. Key features of the app are anxiety monitoring, self-help techniques, and social support via a mobile forum ("the Social Cloud"). This paper presents unique insights into eMental health app usage patterns and explores user behaviors and usage of self-help techniques. OBJECTIVE: The objective of our study was to investigate behavioral engagement and to establish discernible usage patterns of the app linked to the features of anxiety monitoring, ratings of self-help techniques, and social participation. METHODS: We use data mining techniques on aggregate data obtained from 105,380 registered users of the app's cloud services. RESULTS: Engagement generally conformed to common mobile participation patterns with an inverted pyramid or "funnel" of engagement of increasing intensity. We further identified 4 distinct groups of behavioral engagement differentiated by levels of activity in anxiety monitoring and social feature usage. Anxiety levels among all monitoring users were markedly reduced in the first few days of usage with some bounce back effect thereafter. A small group of users demonstrated long-term anxiety reduction (using a robust measure), typically monitored for 12-110 days, with 10-30 discrete updates and showed low levels of social participation. CONCLUSIONS: The data supported our expectation of different usage patterns, given flexible user journeys, and varying commitment in an unstructured mobile phone usage setting. We nevertheless show an aggregate trend of reduction in self-reported anxiety across all minimally-engaged users, while noting that due to the anonymized dataset, we did not have information on users also enrolled in therapy or other intervention while using the app. We find several commonalities between these app-based behavioral patterns and traditional therapy engagement. PMID- 30287416 TI - Designing a Patient Portal for Patient-Centered Care: Cross-Sectional Survey. AB - BACKGROUND: In recent literature, patient portals are considered as important tools for the delivery of patient-centered care. To date, it is not clear how patients would conceptualize a patient portal and which health information needs they have when doing so. OBJECTIVE: This study aimed (1) to investigate health information needs, expectations, and attitudes toward a patient portal and (2) to assess whether determinants, such as patient characteristics, health literacy, and empowerment status, can predict two different variables, namely the importance people attribute to obtaining health information when using a patient portal and the expectations concerning personal health care when using a patient portal. METHODS: We conducted a cross-sectional survey of the Flemish population on what patients prefer to know about their digital health data and their expectations and attitudes toward using a patient portal to access their electronic health record. People were invited to participate in the survey through newsletters, social media, and magazines. We used a questionnaire including demographics, health characteristics, health literacy, patient empowerment, and patient portal characteristics. RESULTS: We received 433 completed surveys. The health information needs included features such as being notified when one's health changes (371/396, 93.7%), being notified when physical parameters increase to dangerous levels (370/395, 93.7%), observing connections between one's symptoms or diseases or biological parameters (339/398, 85.2%), viewing the evolution of one's health in function of time (333/394, 84.5%), and viewing information about the expected effect of treatment (349/395, 88.4%). Almost 90% (369/412) of respondents were interested in using a patient portal. Determinants of patients' attachment for obtaining health information on a patient portal were (1) age between 45 and 54 years (P=.05); (2) neutral (P=.03) or interested attitude (P=.008) toward shared decision making; and (3) commitment to question physicians' decisions (P=.03, R2=0.122). Determinants of patients' expectations on improved health care by accessing a patient portal were (1) lower education level (P=.04); (2) neutral (P=.03) or interested attitude (P=.008) toward shared decision making; and (3) problems in understanding health information (P=.04; R2=0.106). CONCLUSIONS: The interest in using a patient portal is considerable in Flanders. People would like to receive alerts or some form of communication from a patient portal in case they need to act to manage their health. Determinants such as education, attached importance to shared decision making, difficulties in finding relevant health information, and the attached importance in questioning the decisions of physicians need to be considered in the design of a patient portal. PMID- 30287417 TI - Identifying the Underlying Factors Associated With Patients' Attitudes Toward Antidepressants: Qualitative and Quantitative Analysis of Patient Drug Reviews. AB - BACKGROUND: Nonadherence to antidepressants is a major obstacle to deriving antidepressants' therapeutic benefits, resulting in significant burdens on the individuals and the health care system. Several studies have shown that nonadherence is weakly associated with personal and clinical variables but strongly associated with patients' beliefs and attitudes toward medications. Patients' drug review posts in online health care communities might provide a significant insight into patients' attitude toward antidepressants and could be used to address the challenges of self-report methods such as patients' recruitment. OBJECTIVE: The aim of this study was to use patient-generated data to identify factors affecting the patient's attitude toward 4 antidepressants drugs (sertraline [Zoloft], escitalopram [Lexapro], duloxetine [Cymbalta], and venlafaxine [Effexor XR]), which in turn, is a strong determinant of treatment nonadherence. We hypothesized that clinical variables (drug effectiveness; adverse drug reactions, ADRs; perceived distress from ADRs, ADR-PD; and duration of treatment) and personal variables (age, gender, and patients' knowledge about medications) are associated with patients' attitude toward antidepressants, and experience of ADRs and drug ineffectiveness are strongly associated with negative attitude. METHODS: We used both qualitative and quantitative methods to analyze the dataset. Patients' drug reviews were randomly selected from a health care forum called askapatient. The Framework method was used to build the analytical framework containing the themes for developing structured data from the qualitative drug reviews. Then, 4 annotators coded the drug reviews at the sentence level using the analytical framework. After managing missing values, we used chi-square and ordinal logistic regression to test and model the association between variables and attitude. RESULTS: A total of 892 reviews posted between February 2001 and September 2016 were analyzed. Most of the patients were females (680/892, 76.2%) and aged less than 40 years (540/892, 60.5%). Patient attitude was significantly (P<.001) associated with experience of ADRs, ADR-PD, drug effectiveness, perceived lack of knowledge, experience of withdrawal, and duration of usage, whereas oth age (F4,874=0.72, P=.58) and gender (chi24=2.7, P=.21) were not found to be associated with patient attitudes. Moreover, modeling the relationship between variables and attitudes showed that drug effectiveness and perceived distress from adverse drug reactions were the 2 most significant factors affecting patients' attitude toward antidepressants. CONCLUSIONS: Patients' self-report experiences of medications in online health care communities can provide a direct insight into the underlying factors associated with patients' perceptions and attitudes toward antidepressants. However, it cannot be used as a replacement for self-report methods because of the lack of information for some of the variables, colloquial language, and the unstructured format of the reports. PMID- 30287418 TI - microRNA-181a-5p antisense oligonucleotides attenuate osteoarthritis in facet and knee joints. AB - OBJECTIVES: We recently identified microRNA-181a-5p (miR-181a-5p) as a critical mediator involved in the destruction of lumbar facet joint (FJ) cartilage. In this study, we tested if locked nucleic acid (LNA) miR-181a-5p antisense oligonucleotides (ASO) could be used as a therapeutic to limit articular cartilage degeneration. METHODS: We used a variety of experimental models consisting of both human samples and animal models of FJ and knee osteoarthritis (OA) to test the effects of LNA-miR-181a-5p ASO on articular cartilage degeneration. Histopathological analysis including immunohistochemistry and in situ hybridisation were used to detect key OA catabolic markers and microRNA, respectively. Apoptotic/cell death markers were evaluated by flow cytometry. qPCR and immunoblotting were applied to quantify gene and protein expression. RESULTS: miR-181a-5p expression was increased in human FJ OA and knee OA cartilage as well as injury-induced FJ OA (rat) and trauma-induced knee OA (mouse) cartilage compared with control cartilage, correlating with classical OA catabolic markers in human, rat and mouse cartilage. We demonstrated that LNA-miR-181a-5p ASO in rat and mouse chondrocytes reduced the expression of cartilage catabolic and chondrocyte apoptotic/cell death markers in vitro. Treatment of OA-induced rat FJ or mouse knee joints with intra-articular injections of in vivo grade LNA-miR 181a-5p ASO attenuated cartilage destruction, and the expression of catabolic, hypertrophic, apoptotic/cell death and type II collagen breakdown markers. Finally, treatment of LNA-miR-181a-5p ASO in cultures of human knee OA chondrocytes (in vitro) and cartilage explants (ex vivo) further demonstrated its cartilage protective effects. CONCLUSIONS: Our data demonstrate, for the first time, that LNA-miR-181a-5p ASO exhibit cartilage-protective effects in FJ and knee OA.

PMID- 30287421 TI - The RECK tumor-suppressor protein binds and stabilizes ADAMTS10. AB - The tumor suppressor protein RECK has been implicated in the regulation of matrix metalloproteinases (MMPs), NOTCH-signaling and WNT7-signaling. It remains unclear, however, how broad the spectrum of RECK targets extends. To find novel RECK binding partners, we took the unbiased approach of yeast two-hybrid screening. This approach detected ADAMTS10 as a RECK-interactor. ADAMTS10 has been characterized as a metalloproteinase involved in fibrillin-rich microfibril biogenesis, and its mutations have been implicated in the connective tissue disorder Weill-Marchesani syndrome. Experiments in vitro using recombinant proteins expressed in mammalian cells indicated that RECK indeed binds ADAMTS10 directly, that RECK protects ADAMTS10 from fragmentation following chemical activation and that ADAMTS10 interferes with the activity of RECK to inhibit MT1 MMP. In cultured cells, RECK increases the amount of ADAMTS10 associated with the cells. Hence, the present study has uncovered novel interactions between two molecules of known clinical importance, RECK and ADAMTS10.This article has an associated First Person interview with the first author of the paper. PMID- 30287423 TI - The Bawa-Garba principle for medical error. PMID- 30287422 TI - Empagliflozin as Adjunctive to Insulin Therapy in Type 1 Diabetes: The EASE Trials. AB - OBJECTIVE: To evaluate the safety and efficacy of empagliflozin 10- and 25-mg doses plus a unique lower dose (2.5 mg) as adjunct to intensified insulin in patients with type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS: The EASE (Empagliflozin as Adjunctive to inSulin thErapy) program (N = 1,707) included two double-blind, placebo-controlled phase 3 trials: EASE-2 with empagliflozin 10 mg (n = 243), 25 mg (n = 244), and placebo (n = 243), 52-week treatment; and EASE-3 with empagliflozin 2.5 mg (n = 241), 10 mg (n = 248), 25 mg (n = 245), and placebo (n = 241), 26-week treatment. Together they evaluated empagliflozin 10 mg and 25 mg, doses currently approved in treatment of type 2 diabetes, and additionally 2.5 mg on 26-week change in glycated hemoglobin (primary end point) and weight, glucose time-in-range (>70 to <=180 mg/dL), insulin dose, blood pressure, and hypoglycemia. RESULTS: The observed largest mean placebo-subtracted glycated hemoglobin reductions were -0.28% (95% CI -0.42, -0.15) for 2.5 mg, 0.54% (-0.65, -0.42) for 10 mg, and -0.53% (-0.65, -0.42) for 25 mg (all P < 0.0001). Empagliflozin 2.5/10/25 mg doses, respectively, reduced mean weight by 1.8/-3.0/-3.4 kg (all P < 0.0001); increased glucose time-in-range by +1.0/+2.9/+3.1 h/day (P < 0.0001 for 10 and 25 mg); lowered total daily insulin dose by -6.4/-13.3/-12.7% (all P < 0.0001); and decreased systolic blood pressure by -2.1/-3.9/-3.7 mmHg (all P < 0.05). Genital infections occurred more frequently on empagliflozin. Adjudicated diabetic ketoacidosis occurred more with empagliflozin 10 mg (4.3%) and 25 mg (3.3%) but was comparable between empagliflozin 2.5 mg (0.8%) and placebo (1.2%). Severe hypoglycemia was rare and frequency was similar between empagliflozin and placebo. CONCLUSIONS: Empagliflozin improved glycemic control and weight in T1D without increasing hypoglycemia. Ketoacidosis rate was comparable between empagliflozin 2.5 mg and placebo but increased with 10 mg and 25 mg. Ketone monitoring for early ketoacidosis detection and intervention and lower empagliflozin doses may help to reduce this risk.

AB - Chronic kidney disease (CKD) is common. A small proportion of patients with CKD progress to require interventions, which may include dialysis. Monitoring patients with CKD is supported by national guidelines. Monitoring systems to plan management of CKD vary in form. A novel monitoring system, the virtual CKD clinic (VC) was introduced at our hospital. The VC is a non-face-to-face results review of patients with CKD. We found that the VC was an effective monitoring system. None of the patients from the VC required emergency dialysis, suggesting robust surveillance. Survival was similar to patients with CKD discharged to primary care. PMID- 30287424 TI - Acute Kidney Injury among Hospitalized Children in China. AB - BACKGROUND AND OBJECTIVES: High-quality epidemiologic data on AKI in children are particularly lacking in developing countries. This study aimed to assess the epidemiology and clinical correlates of AKI among hospitalized children in China. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We performed a multicenter study, in a cohort of hospitalized children aged 1 month to 18 years, from 25 general and children's hospitals in China during 2013-2015. We obtained patient-level data from the electronic hospitalization information system and laboratory databases of all children who had at least two serum creatinine tests within any 7-day window during their first 30 days of hospitalization. We identified AKI events according to the creatinine criteria of Kidney Disease Improving Global Outcomes. The in-hospital outcomes of AKI, including mortality, kidney recovery, and length of stay, were assessed. We estimated the corresponding hazard ratios using a Cox proportional hazard model, with adjustment for age, sex, comorbidities, and clinical procedures. RESULTS: A total of 19,908 (20%) patients with AKI were identified among 101,836 pediatric inpatients, of which 7220 (7%) were community acquired and 12,688 (13%) were hospital acquired. Up to 96% of these AKI events were not diagnosed on the discharge records. The cumulative incidence of AKI in infants (28%) was twice that in adolescents (12%). The profiles of risk factors differed between community-acquired and hospital acquired AKI and varied with age. Diarrhea and sepsis were the top risk factors for community-acquired AKI, each contributing 6% of the risk. Congenital heart disease/cardiac surgery was the major risk factor for hospital-acquired AKI, contributing to 19% of cases. Exposure to nephrotoxic drugs, mostly nonsteroidal anti-inflammatory drugs and proton pump inhibitors, was common in hospitalized children and was associated with a higher risk of AKI. Death occurred in 842 out of 19,908 patients (4%) with AKI versus 450 out of 81,478 children (0.5%) without AKI. The risk of in-hospital death was higher among children with severe AKI, shock, and respiratory failure. Pediatric AKI was associated with longer hospital stay and higher daily cost, even after adjustment for covariates. CONCLUSIONS: Pediatric AKI is common and is substantially underdiagnosed in China. PMID- 30287428 TI - NEWS 2 - too little evidence to implement? AB - The Royal College of Physicians (RCP) recently published the National Early Warning Score 2 (NEWS2), aiming to improve safety for patients with hypercapnic respiratory failure by suggesting a separate oxygen saturation (SpO2) parameter scoring system for such patients. A previously published study of patients (n=2,361 admissions) with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) demonstrated alternative scoring systems at admission did not outperform the original NEWS. Applying NEWS2 SpO2 parameters to this previously described cohort would have resulted in 44% (n=27/62) of patients who scored >=7 points on the original NEWS and subsequently died being placed in a lower call out threshold. NEWS2 loses the benefits of a unified, standardised scoring system and we suggest prospective research in this area before applying this adjustment. PMID- 30287427 TI - Immunoglobulin use in immune deficiency in the UK: a report of the UKPID and National Immunoglobulin Databases. AB - Supply of immunoglobulin in the UK faces pressures due to increasing demand, cost and variable supply. This paper describes immunoglobulin replacement therapy (IGRT) in primary immunodeficiency (PID) and secondary immunodeficiency (SID) to assist in the ongoing planning of UK immunoglobulin provision. A retrospective analysis of the National Immunoglobulin Database and the UKPID registry was carried out. In total, 3,222 patients are registered as receiving IGRT for immunodeficiencies. Predominately antibody disorders made up the largest diagnostic category (61% of patients). The total cost of IGRT for immunodeficiency for 2015/16 was L40,673,350; an average annual cost of L1,099,254 per centre and L12,124 per PID patient. SCIg accounted for 43.8% and 50.1% of IGRT, with home therapy accounting for 42.7% and 57.5% of place of therapy in the National Immunoglobulin Database and UKPID registry respectively. In 2015/16 use of immunoglobulin in SID increased by 24% over the previous financial year. The overall trends of increasing demand in immunology are mirrored in other specialties, most notably neurology and haematology. These data are the first national overview of IGRT for immunodeficiencies, providing a valuable resource for clinicians and policy makers in the ongoing management of UK immunoglobulin supply. PMID- 30287429 TI - Are we on the same page? Exploring the role of the geriatrician in the care of the older surgical patient from the perspective of surgeons and geriatricians. AB - There is increasing recognition that the ageing population represents a challenge to existing surgical services. National reports recommend that geriatricians proactively review older surgical patients to improve care and outcomes. However, this approach has not been widely translated into practice. A qualitative study was conducted using 12 semi-structured interviews of surgeons and geriatricians to explore the role of the geriatrician in the care of older surgical patients. Participants agreed that the current system did not meet the needs of older surgical patients. Geriatricians valued their holistic way of working but these generalist skills can overlap with other specialties, seen by some as wasting resources. Three models of care were proposed, with the ownership and location of the patient as well as the role of education being the key variables. The main obstacle preventing integrated working was the concern of de-skilling the surgeons, narrowing their role to that of a 'technician'. Other barriers included loss of autonomy; lack of evidence; and a lack of recognition of the need for a geriatrician. There is acceptance that closer working practices are necessary to meet the needs of this complex patient group but a lack of evidence, together with significant human factors, are challenges that must be addressed to realise this aim. PMID- 30287430 TI - The British Army's contribution to tropical medicine. AB - Infectious disease has burdened European armies since the Crusades. Beginning in the 18th century, therefore, the British Army has instituted novel methods for the diagnosis, prevention and treatment of tropical diseases. Many of the diseases that are humanity's biggest killers were characterised by medical officers and the acceptance of germ theory heralded a golden era of discovery and development. Luminaries of tropical medicine including Bruce, Wright, Leishman and Ross firmly established the British Army's expertise in this area. These innovations led to the prevention of many deaths of both military personnel and civilians. British Army doctors were instrumental in establishing many of the teaching facilities that we now consider to be global leaders in tropical medicine. The impact of the Army in this field has certainly been significant in the past and its contribution continues to this day. PMID- 30287431 TI - Acute kidney injury and 'nephrotoxins': mind your language. AB - The introduction of the term 'acute kidney injury' (AKI) along with an international classification scheme,1 caused some initial confusion, but most clinicians and many patients now understand that the term 'injury' denotes damage to the internal workings of the kidney, rather than physical trauma. However, of greater concern is the use of the term 'nephrotoxic' to include drugs that are, in most settings, nephroprotective. We argue that this imprecise terminology, unfortunately adopted by the National Institute for Health and Care Excellence (NICE) among others, is potentially harmful, and that the terms 'nephrotoxin' and 'nephrotoxic' should not be used to describe haemodynamically mediated and fully reversible effects of some drugs on excretory function. PMID- 30287432 TI - An update on the use of inhaled therapy in COPD. AB - Inhaled corticosteroids represent the mainstay of pharmacological treatment for reversible airways disease, and traditionally have had widespread use in non reversible chronic obstructive pulmonary disease (COPD). However, use in this group may expose patients to an increased risk of pneumonia, without significant benefit to symptoms or exacerbation frequency. Here we provide a guide to the use of inhaled therapy in COPD for the general physician. PMID- 30287433 TI - What is the significance of monoclonal gammopathy of undetermined significance? AB - Monoclonal gammopathy of undetermined significance (MGUS) is characterised by the presence of a monoclonal paraprotein in the blood, without the characteristic end organ damage seen in multiple myeloma. MGUS is more common in older age groups and has a risk of progression to myeloma of 1% per year. Population screening is not currently recommended, but retrospective studies have suggested improvements in myeloma outcomes in those under MGUS follow-up; in addition, MGUS has associated complications, including fracture, osteoporosis, renal disease and infection, which can be treated. Given this increasing evidence of disease related directly to MGUS, strategies for early identification might be needed. In this review, we discuss the complications of MGUS and whether MGUS fulfils the criteria needed to implement a screening programme. We also highlight areas where more evidence is needed, including identification of a higher risk population to make screening more practical and economically viable. PMID- 30287434 TI - Later careers - regenerating the medical workforce. AB - We have a medical workforce crisis where we have insufficient trainees, demonstrated by rota gaps, and in turn nearly half of advertised consultant physician posts cannot be appointed to. Most physicians retire around age 62, and already 5% of the total consultant workforce is those who have retired and returned. If those reaching retirement age chose not to retire but continue working less than full time this would, at least in part, benefit the workforce and utilise valuable skills and experience to the benefit of the individual, the wider medical community and therefore our patients. PMID- 30287435 TI - An old disease re-emerging: acute rheumatic fever. AB - We present the case of a 41-year-old Australian woman with a 3-day history of fevers and migratory polyarthritis. Three weeks prior she had been treated by her GP with phenoxymethylpenicillin for acute tonsillitis. Examination confirmed synovitis. Systemic assessment including cardiovascular, neurological and skin examination was unremarkable. Abnormal investigations included a leucocytosis with neutrophilia, C-reactive peptide of 116 mg/L, erythrocyte sedimentation rate of 103 mm/hour and acute transaminitis. The antistreptolysin O titre was 304 IU, which increased to 1,250 IU after 2 weeks. Troponin T, electrocardiogram and echocardiography were all normal. The patient was treated for acute rheumatic fever with corticosteroids and a 10-day course of cephalexin. After 8 weeks, she made a full recovery and had normalised inflammatory markers and liver biochemistry. She was then commenced on monthly prophylactic intramuscular benzathine penicillin. This case study aims to raise awareness of the presentation, diagnosis and management of acute rheumatic fever. PMID- 30287436 TI - Pneumomediastinum complicating adult-onset measles. AB - Adult-onset measles is rare in the UK, particularly in patients with a complete vaccination history.We present a case of a UK-born patient who received all childhood vaccinations, had no history of recent travel or unwell contacts who was diagnosed with measles complicated by pneumomediastinum. This case highlights the need to consider measles in any patient presenting with a constellation of a macular rash, fever and conjunctivitis, regardless of vaccination status. The nature of the rash can provide an important clue to the diagnosis. Liaison with infection specialists facilitates early diagnosis, allowing for appropriate initial investigations, improving clinical management and early infection control precautions being instituted. PMID- 30287437 TI - Spontaneous splenic rupture secondary to dabigatran: the last in a series of unfortunate events. AB - We present the case of a 77-year-old woman who had an accidental fall in her garden, resulting in a fracture of her left ankle. After manipulation of the fracture, she developed sudden onset shortness of breath. An echo led to the diagnosis of Takotsubo cardiomyopathy. Shortly after this she developed sudden onset receptive and expressive dysphasia. Magnetic resonance imaging (MRI) of the head confirmed a left parietal infarct thought to be secondary to left ventricular thrombus formation. She was started on dabigatran. A few days later, she developed abdominal pain, and was subsequently diagnosed with a spontaneous splenic rupture. This case was interesting due to the unusual chain of events following a simple fall, and also a rare complication of anticoagulant therapy. PMID- 30287438 TI - Seizures and epilepsy in the acute medical setting: presentation and management. AB - Epileptic seizures are a common cause for presentation to acute medical services. Whether presenting with an isolated, unprovoked seizure or with status epilepticus, a good understanding of seizures and their mimics ensures appropriate investigation and treatment. This article describes the practical aspects of the management of patients presenting with seizures to the emergency department or the acute medical unit. PMID- 30287439 TI - Functional neurological disorders: acute presentations and management. AB - Functional neurological disorders (FND) are common and associated with significant morbidity and healthcare costs. Patients with FND often present acutely, particularly with dissociative seizures (resembling epilepsy) or persistent weakness resembling a stroke. History and careful observation and examination are critical to diagnosis, as investigations will often be normal or non-contributory. The nature of convulsive movements in dissociative seizures often differs from that in epilepsy, and long duration of individual events, waxing and waning, closed eyes and high reported frequency in an apparently well individual are all suggestive. In those with stroke-like episodes, demonstration of normal power even briefly (eg Hoover's sign, 'give way' weakness) together with distractability are positive physical features indicating a functional disorder. A positive diagnosis and clear non-judgemental explanation, backed up by reliable information sources associated with prompt onward referral to a neurologist can greatly reduce distress and ultimately improve outcomes. PMID- 30287441 TI - Assessment of acute headache in adults - what the general physician needs to know. AB - Headache is common. Up to 5% of attendances to emergency departments and acute medical units are due to headache. Headache is classified as either primary (eg migraine, cluster headache) or secondary to another cause (eg meningitis, subarachnoid haemorrhage). Even in the acute setting the majority of cases are due to primary causes. The role of the attending physician is to take a comprehensive history to diagnose and treat benign headache syndromes while ruling out sinister aetiologies. This brief article summarises the approach to assessment of headache presenting in acute and emergency care. PMID- 30287440 TI - Acute neurology: a suggested approach. AB - Acute neurological problems are common, accounting for 10-20% of medical admissions. In the coming years, there will be increased neurology involvement in the acute care of these patients complementing traditional outpatient-based services. Models of acute neurology are reliant on close collaboration between the emergency department, acute medicine and neurology and should integrate with existing hyperacute stroke pathways. In this article the authors briefly describe the two models of acute neurology set up recently in our neuroscience group and suggest a clinical approach that may help non-neurologists involved in acute care settings. The authors emphasise some of the lessons learnt in delivering the service, particularly the importance of focusing on the acute problem and tailoring the examination and investigations to tackling it in the context of the patient's functional level and personal circumstances. Early neurology intervention can reduce admission and hospital length of stay. PMID- 30287443 TI - Lesson of the month 1: Sodium valproate-induced encephalopathy. AB - A 69-year-old man developed reduced consciousness of sudden onset. Examination and parameters were normal, except for a Glasgow Coma Scale (GCS) score of six. Brain imaging and blood tests were also normal, except for high plasma ammonia. His past medical history included epilepsy, hypertension and colitis. He was taking multiple antiepileptic medications, including sodium valproate, with no recent dose alterations. Medical intervention led to the sodium valproate being stopped and naloxone being administered. The patient's level of responsiveness and ammonia levels gradually improved. The patient was also being treated with ciprofloxacin for a urinary tract infection and a newly developed syndrome of inappropriate antidiuretic hormone secretion treated with demeclocycline. There is an association between long-term sodium valproate use and low carnitine levels, especially in the setting of polypharmacy. This in turn precipitates hyperammonaemia and encephalopathy. This case highlights the importance of an adequate drug history and the awareness of serious but uncommon adverse effects. PMID- 30287442 TI - CME Neurology (120487): self-assessment questionnaire.

A constellation of clinical and biochemical features led to a search for medical causes of his low mood, which uncovered ectopic adrenocorticotropic hormone (ACTH) secretion. Post-mortem examination showed that the source of ACTH was small cell neuroendocrine carcinoma of the prostate, and that the patient had died from the sequelae of profound immune suppression.

PMID- 30287455 TI - Do All Patients with Multiple Sclerosis Benefit from the Use of Contrast on Serial Follow-Up MR Imaging? A Retrospective Analysis. AB - BACKGROUND AND PURPOSE: Patients with multiple sclerosis routinely have MR imaging with contrast every 6-12 months to assess response to medication. Multiple recent studies provide evidence of tissue deposition of MR imaging contrast agents, questioning the long-term safety of these agents. The goal of this retrospective image-analysis study was to determine whether contrast could be reserved for only those patients who show new MS lesions on follow-up examinations. MATERIALS AND METHODS: We retrospectively reviewed brain MRIs of 138 patients. To increase our sensitivity, we used a previously described computerized image-comparison software to evaluate the stability or progression of multiple sclerosis white matter lesions in noncontrast FLAIR sequences. We correlated these findings with evidence of contrast-enhancing lesions on the enhanced T1 sequence from the same scan. RESULTS: Thirty-three scans showed an increase in white matter lesion burden. Among those 33 patients, 14 examinations also demonstrated enhancing new lesions. While we found a single example of enhancement of a pre-existing white matter lesion that appeared unchanged in size, that same examination showed an overall increase in lesion burden with enhancement of other, new lesions. Thus, we found that all patients with enhancing lesions had evidence of progression on their noncontrast imaging. CONCLUSIONS: Because all enhancing lesions were associated with new lesions on unenhanced imaging and progression was only evident in 24% of patients, in patients with relapsing-remitting MS, it is reasonable to consider reserving contrast for only those patients with evidence of progression on noncontrast MR images. PMID- 30287457 TI - Reply. PMID- 30287456 TI - Impact of Ischemic Lesion Location on the mRS Score in Patients with Ischemic Stroke: A Voxel-Based Approach. AB - BACKGROUND AND PURPOSE: Previous studies indicated that ischemic lesion volume might be a useful surrogate marker for functional outcome in ischemic stroke but should be considered in the context of lesion location. In contrast to previous studies using the ROI approach, which has several drawbacks, the present study aimed to measure the impact of ischemic lesion location on functional outcome using a more precise voxelwise approach. MATERIALS AND METHODS: Datasets of patients with acute ischemic strokes from the Multicenter Randomized Clinical Trial of Endovascular Therapy for Acute Ischemic Stroke in the Netherlands (MR CLEAN) were used. Primary outcome was functional outcome as assessed by the modified Rankin Scale 3 months after stroke. Ischemic lesion volume was determined on CT scans 3-9 days after stroke. Voxel-based lesion-symptom mapping techniques, including covariates that are known to be associated with functional outcome, were used to determine the impact of ischemic lesion location for outcome. RESULTS: Of the 500 patients in the MR CLEAN trial, 216 were included for analysis. The mean age was 63 years. Lesion-symptom mapping with inclusion of covariates revealed that especially left-hemispheric lesions in the deep periventricular white matter and adjacent internal capsule showed a great influence on functional outcome. CONCLUSIONS: Our study confirms that infarct location has an important impact on functional outcome of patients with stroke and should be considered in prediction models. After we adjusted for covariates, the left-hemispheric corticosubcortical fiber tracts seemed to be of higher functional importance compared with cortical lesions. PMID- 30287458 TI - Spinal Coccidioidomycosis: MR Imaging Findings in 41 Patients. AB - BACKGROUND AND PURPOSE: Coccidioides immitis is a dimorphic fungus endemic to the Southwest United States and Mexico, and at our institution, it is a relatively common pathogen presenting with a broad spectrum of associated spine diseases. We describe the various spinal manifestations resulting from coccidioidal infection and provide MR imaging examples from 41 pathologically proved cases. MATERIALS AND METHODS: Retrospective electronic medical record and PACS searches were performed. Patients found to have both MR imaging findings positive for infection and confirmative biopsy and/or CSF studies were included. Abnormal MR imaging findings were identified, categorized, and quantified. Patient demographics and associated intracranial involvement if present were also recorded. RESULTS: Forty one patients were included. Positive findings were categorized as leptomeningeal enhancement (26 patients, 63%), arachnoiditis (22 patients, 54%), osteomyelitis discitis (14 patients, 34%), cord edema (11 patients, 27%), and true syrinx (3 patients, 7%). Thirty patients had documented brain involvement (73%), most commonly in the form of basilar meningitis. Four patients were positive for HIV (10%). Fifteen patients had pulmonary manifestations at presentation (37%). CONCLUSIONS: C immitis results in various spinal manifestations, most commonly leptomeningeal enhancement and arachnoiditis/adhesive disease followed by osteomyelitis, which may resemble tuberculous or pyogenic infection on MR imaging. PMID- 30287459 TI - Flow-Diversion Effect of LEO Stents: Aneurysm Occlusion and Flow Remodeling of Covered Side Branches and Perforators. AB - BACKGROUND AND PURPOSE: Flow diversion with intermediate-porosity stents (braided stents) has been recently reported for distally located small aneurysms. The aim of this study was to evaluate the flow-diversion effect of LEO stents on covered vessels and for aneurysms treated with sole stent-placement therapy. MATERIALS AND METHODS: We retrospectively evaluated the following outcomes: 1) remodeling of covered side branches and perforators (extra-aneurysmal flow remodeling), and 2) the occlusion rate of aneurysms treated with sole stent-placement therapy (intra-aneurysmal flow remodeling). RESULTS: Seventy-six patients with 98 covered vessels were studied. Overall, 89 covered arteries (91%) were normal, 7 showed narrowing (7%), and 2 (2%) were occluded (1 posterior communicating artery and 1 MCA) without related complications (mean DSA follow-up, 14 months). Univariate and multivariate analyses highlighted smoking (P = .03) and the length of follow up (P = .002) as factors associated with arterial remodeling. Of the 17 Sylvian (lenticulostriate arteries) and 7 basilar perforators, 1 (4%) group of Sylvian perforators covered with double stents had asymptomatic remodeling. Ten aneurysms (mean size, 3.5 mm) were treated with LEO stents as stent monotherapy (5 recanalized after coiling and 5 directly treated with the LEO). Complete occlusion (Raymond-Roy I) was achieved in 70% of aneurysms (mean follow-up, 14 months). The Raymond-Roy I occlusion rate among recanalized aneurysms and those directly treated with LEO stents was 80% and 60%, respectively (P = .9). CONCLUSIONS: The rate of flow remodeling on the covered arteries and perforators was 9% and 4%, respectively, and was clinically irrelevant in all cases. Complete occlusion of aneurysms treated with sole stent-placement therapy was 70%. These data stress the flow-diversion properties of LEO stents. PMID- 30287461 TI - Fluoroscopically Guided Facet Injections: Comparison of Intra-Articular and Periarticular Steroid and Anesthetic Injection on Immediate and Short-Term Pain Relief. AB - BACKGROUND AND PURPOSE: The effectiveness of facet injections is unclear in the literature. Our objective was to determine the immediate and short-term efficacy of intra-articular and periarticular steroid/anesthetic injections for facet mediated lumbar pain. MATERIALS AND METHODS: All outpatient fluoroscopically guided facet injections at a single institution during a 54-month period were retrospectively and independently reviewed by 2 musculoskeletal (MSK) trained radiologists. All intra-articular, all periarticular, and partial intra /periarticular injection locations were determined. Periarticular and partial peri-/intra-articular injections were combined for analysis. Preinjection, immediate, and 1-week postinjection numeric pain scores, patient age, sex, anesthetic/steroid mixture, fluoroscopic time, and physician performing the procedure were recorded. RESULTS: Seventy-seven patients (mean age, 51.1 years) had 100 procedures with 205 total facet joints injected. All intra-articular, all periarticular, and partial peri-/intra-articular injections constituted 54%, 20%, and 26% of the cases, respectively. The immediate and 1-week postprocedural change in pain was -3.7 (95% CI, -4.5 to -2.8; P < .001) and -1.4 (95% CI, -2.2 to -0.6; P = .001) for the all intra-articular and -3.6 (95% CI, -4.4 to -2.9; P < .001) and -1.2 (95% CI, -1.9 to -0.4; P = .002) for the combined group. Changes in immediate pain were significantly associated with the prepain level (P < .001) and patient age (P = .024) but not with the anesthetic used. Analyses revealed no significant difference in pain reduction between the groups either immediately or 1 week postinjection. Intra-articular injections required less fluoroscopic time (geometric mean, 39 versus 52 seconds) (P = .005). CONCLUSIONS: Intra-articular and periarticular fluoroscopically guided facet injections provide statistically significant and similar pain relief both immediately and 1 week postinjection. PMID- 30287460 TI - Subtraction CTA: An Alternative Imaging Option for the Follow-Up of Flow-Diverter Treated Aneurysms? AB - BACKGROUND AND PURPOSE: This was a pilot study to explore the diagnostic accuracy and safety of subtraction CTA combined with a single-energy metal artifact reduction algorithm (SEMAR) compared to DSA for the evaluation of intracranial aneurysm occlusion after flow diverter treatment. MATERIALS AND METHODS: We included patients treated with a flow diverter for an unruptured intracranial aneurysm between November 2015 and November 2016. The patient cohort comprised 2 groups: those who underwent follow-up imaging 1 month after flow-diverter treatment and those with a known residual intracranial aneurysm after flow diverter treatment who underwent imaging at regular follow-ups. Full-brain subtraction CTA was performed on a 320-detector row CT system. A low-dose non enhanced volume acquisition was followed by a contrast-enhanced volume CTA. Iterative and noise-reduction filters, SEMAR, and SURESubtraction algorithms were applied. DSA was performed on a flat panel C-arm angiography system. Standard posteroanterior, lateral, 3D, and detailed 2D acquisitions were performed. Imaging was independently scored by 2 clinicians. Aneurysm occlusion (Raymond scale) was our primary outcome parameter. RESULTS: Thirteen intracranial aneurysms were evaluated with subtraction CTA and DSA. Nine aneurysm remnants were demonstrated by both subtraction CTA and DSA. The sensitivity and specificity of subtraction CTA for the detection of aneurysm occlusion were 100% (95% CI, 82.41%-100%) and 100% (95% CI, 67.55%-100%), respectively. Agreement between readers was perfect (kappa = 1.0). The smallest neck remnant detected on subtraction CTA was 1.2 mm. No complications occurred. CONCLUSIONS: Subtraction CTA with single-electron metal artifact reduction is effective in the reduction of metal artifacts of flow diverters and might therefore be a viable alternative in the assessment of intracranial aneurysm occlusion after flow diverter treatment.

AB - Cross-sectional studies have demonstrated that obstructive sleep apnoea (OSA) and metabolic syndrome (MetS) are often associated, but whether a temporal relationship exists is unknown. We aimed to investigate the effect of OSA on the risk of developing MetS in the general population.A prospective study was conducted combining two population-based samples: Episono (Brazil) and HypnoLaus (Switzerland). MetS was assessed according to unified criteria. Polysomnography (PSG) was performed at baseline and follow-up in Episono, and at baseline in HypnoLaus. OSA was defined according to the apnoea-hypopnoea index as mild (>=5- <15 events h-1) and moderate-to-severe (>=15 events.h-1). We included 1853 participants (mean+/-sd age 52+/-13 years, 56% female) without MetS at baseline.After mean+/-sd 6+/-1 years, 318 (17.2%) participants developed MetS. Moderate-to-severe OSA was independently associated with incident MetS (OR 2.58, 95% CI 1.61-4.11) and increased the number of MetS components from baseline to follow-up through mediation of the percentage of time with arterial oxygen saturation <90%. Subset analysis in Episono confirmed that the increase in this parameter between baseline and follow-up PSGs represented a risk factor for incident MetS (OR 1.42, 95% CI 1.04-1.95, for each 10% increase).OSA is independently associated with an increased risk of developing MetS through mediation of nocturnal hypoxaemia in the general population.

PMID- 30287474 TI - Endoplasmic Reticulum Homeostasis Is Modulated by the Forkhead Transcription Factor FKH-9 During Infection of Caenorhabditis elegans. AB - Animals have evolved critical mechanisms to maintain cellular and organismal proteostasis during development, disease, and exposure to environmental stressors. The Unfolded Protein Response (UPR) is a conserved pathway that senses and responds to the accumulation of misfolded proteins in the endoplasmic reticulum (ER) lumen. We have previously demonstrated that the IRE-1-XBP-1 branch of the UPR is required to maintain Caenorhabditis elegans ER homeostasis during larval development in the presence of pathogenic Pseudomonas aeruginosa In this study, we identify loss-of-function mutations in four conserved transcriptional regulators that suppress the larval lethality of xbp-1 mutant animals caused by immune activation in response to infection by pathogenic bacteria: FKH-9, a forkhead family transcription factor; ARID-1, an ARID/Bright domain-containing transcription factor; HCF-1, a transcriptional regulator that associates with histone modifying enzymes; and SIN-3, a subunit of a histone deacetylase complex. Further characterization of FKH-9 suggests that loss of FKH-9 enhances resistance to the ER toxin tunicamycin and results in enhanced ER-associated degradation (ERAD). Increased ERAD activity of fkh-9 loss-of-function mutants is accompanied by a diminished capacity to degrade cytosolic proteasomal substrates and a corresponding increased sensitivity to the proteasomal inhibitor bortezomib. Our data underscore how the balance between ER and cytosolic proteostasis can be influenced by compensatory activation of ERAD during the physiological ER stress of infection and immune activation. PMID- 30287476 TI - Association between socioeconomic status and risk of hospitalization due to child maltreatment in the USA. AB - Child maltreatment remains a significant problem in the USA. There is a dearth of literature examining the association of socioeconomic status (SES) and incidence of child maltreatment among hospitalized children across the entire USA. Our aim was to study the association between SES and incidence and mortality from child maltreatment among hospitalized children in the USA. We used 2013-2014 data from the Nationwide Inpatient Sample, a discharge database representative of all hospitals in the USA. International Classification of Diseases-9 codes for general child maltreatment were used to identify patients discharged with a primary diagnosis of child maltreatment. Trends in the incidence and outcomes of child maltreatment were compared with SES based on quartiles (Qx) of median household income. In 2013-2014, there were a total of about 2.3 million pediatric discharges. Out of these, a total of 8985 had a primary diagnosis of child maltreatment. Approximately 40 per cent of the cases were from families with the lowest SES (Q1). In-hospital mortality was 2.4 per cent in Q1 (lowest SES) compared with 0.4 per cent in Q4 (highest SES). We conclude that children from lower SES households have a higher incidence of child maltreatment and have worse outcomes, including significantly higher in-hospital mortality among hospitalized children. This trend was generally consistent across all age groups and ethnicities. To our knowledge, this is the first report studying the association between SES and children with child maltreatment among hospitalized children across the entire USA.

AB - To evaluate the use of plasma haptoglobin (Hp) levels and N-terminal pro-B-type natriuretic peptide (NT-proBNP) in predicting survival in patients with severe acute decompensated heart failure (AHF). Management of AHF is challenging. Identifying markers associated with patient prognosis in this disease is clinically important. In this prospective observational study, plasma Hp and NT proBNP levels were measured. Receiver operating characteristic (ROC) curves were used to identify cut-offs of Hp and NT-proBNP with the greatest specificity and sensitivity for predicting overall survival and cardiovascular-related survival. The cut-off values were tested in patients with AHF (n=41). The cut-off value with the greatest specificity and sensitivity with respect to overall survival and for cardiovascular-related survival for Hp was 177. 1 ng/mL for both outcomes and for NT-proBNP was 34 246.0 pg/mL and 11 848.5 ng/mL, respectively. Using these cut-off values, this study found that patients with lower baseline Hp levels (<177. 1 ng/mL) or higher baseline NT-proBNP (>=34 246 pg/mL) were more likely to have shorter overall survival. Similarly, patients with <177. 1 ng/mL of Hp and >=11 848.5 pg/mL of NT-proBNP had the highest risk of death related to cardiovascular disease. Our findings indicate that Hp and NT-proBNP using specific cut-off values for AHF can be used to determine risk of survival in these patients. PMID- 30287477 TI - The Phosphate Binder Ferric Citrate Alters the Gut Microbiome in Rats with Chronic Kidney Disease. AB - In chronic kidney disease (CKD), the gut microbiome is altered and bacterial derived uremic toxins promote systemic inflammation and cardiovascular disease. Ferric citrate complex is a dietary phosphate binder prescribed for patients with end-stage kidney disease to treat hyperphosphatemia and secondary hyperparathyroidism. Iron is an essential nutrient in both microbes and mammals. This study was undertaken to test the hypothesis that the large iron load administered with ferric citrate in CKD may significantly change the gut microbiome. Male Sprague-Dawley rats underwent 5/6 nephrectomy to induce CKD. Normal control and CKD rats were randomized to regular chow or a 4% ferric citrate diet for 6 weeks. Fecal and cecal microbial DNA was analyzed via 16S ribosomal RNA gene sequencing on the Illumina MiSeq system. CKD rats had lower abundances of Firmicutes and Lactobacillus compared with normal rats and had lower overall gut microbial diversity. CKD rats treated with ferric citrate had improved hemoglobin and creatinine clearance and amelioration of hyperphosphatemia and hypertension. Ferric citrate treatment increased bacterial diversity in CKD rats almost to levels observed in control rats. The tryptophanase-possessing families Verrucomicrobia, Clostridiaceae, and Enterobacteriaceae were increased by ferric citrate treatment. The uremic toxins indoxyl sulfate and p-cresyl sulfate were not increased with ferric citrate treatment. Verrucomicrobia was largely represented by Akkermansia muciniphila, which has important roles in mucin degradation and gut barrier integrity. In summary, ferric citrate therapy in CKD rats was associated with significant changes in the gut microbiome and beneficial kidney and blood pressure parameters. PMID- 30287481 TI - Rare variants of the FMN riboswitch class in Clostridium difficile and other bacteria exhibit altered ligand specificity. AB - Many bacteria use FMN (flavin mononucleotide) riboswitches to control the expression of genes responsible for the biosynthesis and transport of this enzyme cofactor or its precursor, riboflavin. Rare variants of FMN riboswitches found in strains of Clostridium difficile and some other bacteria typically control the expression of proteins annotated as transporters, including multidrug efflux pumps. These RNAs no longer recognize FMN, and differ from the original riboswitch consensus sequence at nucleotide positions normally involved in binding of the ribityl and phosphate moieties of the cofactor. Representatives of one of the two variant subtypes were found to bind the FMN precursor riboflavin and the FMN degradation products lumiflavin and lumichrome. Although the biologically relevant ligand sensed by these variant FMN riboswitches remains uncertain, our findings suggest that many strains of C. difficile might use rare riboswitches to sense flavin degradation products and activate transporters for their detoxification.

AB - Natural killer T (NKT) cells expressing the invariant T cell receptor (iTCR) serve an essential function in clearance of certain pathogens and have been implicated in autoimmune and allergic diseases. Complex effector programs of these iNKT cells are wired in the thymus, and upon thymic egress, they can respond within hours of antigenic challenges, classifying iNKT cells as innate like. It has been assumed that the successful rearrangement of the invariant iTCRalpha chain is the central event in the divergence of immature thymocytes to the NKT cell lineage, but molecular properties that render the iTCR signaling distinct to permit the T cell lineage diversification remain obscure. Here we show that the High Mobility Group (HMG) transcription factor (TF) SOX4 controls the production of iNKT cells by inducing MicroRNA-181 (Mir181) to enhance TCR signaling and Ca2+ fluxes in precursors. These results suggest the existence of tailored, permissive gene circuits in iNKT precursors for innate-like T cell development. PMID- 30287478 TI - SENSITIVE TO SALT1, An Endoplasmic Reticulum-Localized Chaperone, Positively Regulates Salt Resistance. AB - Salt stress seriously affects plant growth and development. Through genetic screening, we identified and characterized an Arabidopsis (Arabidopsis thaliana) sensitive to salt1 (ses1) mutant. SES1 was ubiquitously expressed and induced by salt treatment. The salt-sensitive phenotype of ses1 was due neither to the overaccumulation of Na+ nor to the suppression of salt tolerance-associated genes. SES1 encoded an uncharacterized endoplasmic reticulum (ER)-localized protein. Coinciding with its subcellular distribution, ses1 exhibited overactivation of unfolded protein response genes and was largely influenced by severe ER stress. Biochemical evidence revealed that SES1 functions as an important molecular chaperone to alleviate salt-induced ER stress. Furthermore, the ER stress sensor basic leucine zipper factor17 transactivated SES1 by binding directly to its promoter region. These results provide insights into salt stress responses and ER homeostasis and shed light on the mechanism by which SES1 modulates salt resistance.

AB - The interaction of platelet glycoprotein Ibalpha (GPIbalpha) with von Willebrand factor (VWF) initiates hemostasis after vascular injury and also contributes to pathological thrombosis. GPIbalpha binding to the VWF A1 domain (VWFA1) is a target for antithrombotic intervention, but attempts to develop pharmacologic inhibitors have been hindered by the lack of animal models because of the species specificity of the interaction. To address this problem, we generated a knockin mouse with Vwf exon 28-encoding domains A1 and A2 replaced by the human homolog (VWFh28). VWFh28 mice (M1HA) were crossbred with a transgenic mouse strain expressing human GPIbalpha on platelets (mGPIbalphanull;hGPIbalphaTg; H1MA) to generate a new strain (H1HA) with humanized GPIbalpha-VWFA1 binding. Plasma VWF levels in the latter 3 strains were similar to those of wild-type mice (M1MA). Compared with the strains that had homospecific GPIbalpha-VWF pairing (M1MA and H1HA), M1HA mice of those with heterospecific pairing had a markedly greater prolongation of tail bleeding time and attenuation of thrombogenesis after injury to the carotid artery than H1MA mice. Measurements of GPIbalpha-VWFA1 binding affinity by surface plasmon resonance agreed with the extent of observed functional defects. Ristocetin-induced platelet aggregation was similar in H1HA mouse and human platelet-rich plasma, and it was comparably inhibited by monoclonal antibody NMC-4, which is known to block human GPIbalpha-VWFA1 binding, which also inhibited FeCl3-induced mouse carotid artery thrombosis. Thus, the H1HA mouse strain is a fully humanized model of platelet GPIbalpha-VWFA1 binding that provides mechanistic and pharmacologic information relevant to human hemostatic and thrombotic disorders. PMID- 30287484 TI - Conservative conference: May announces new cancer strategy to boost survival rates. PMID- 30287485 TI - Integrative genomic analysis of mouse and human hepatocellular carcinoma. AB - Cancer genomics has enabled the exhaustive molecular characterization of tumors and exposed hepatocellular carcinoma (HCC) as among the most complex cancers. This complexity is paralleled by dozens of mouse models that generate histologically similar tumors but have not been systematically validated at the molecular level. Accurate models of the molecular pathogenesis of HCC are essential for biomedical progress; therefore we compared genomic and transcriptomic profiles of four separate mouse models [MUP transgenic, TAK1 knockout, carcinogen-driven diethylnitrosamine (DEN), and Stelic Animal Model (STAM)] with those of 987 HCC patients with distinct etiologies. These four models differed substantially in their mutational load, mutational signatures, affected genes and pathways, and transcriptomes. STAM tumors were most molecularly similar to human HCC, with frequent mutations in Ctnnb1, similar pathway alterations, and high transcriptomic similarity to high-grade, proliferative human tumors with poor prognosis. In contrast, TAK1 tumors better reflected the mutational signature of human HCC and were transcriptionally similar to low-grade human tumors. DEN tumors were least similar to human disease and almost universally carried the Braf V637E mutation, which is rarely found in human HCC. Immune analysis revealed that strain-specific MHC-I genotype can influence the molecular makeup of murine tumors. Thus, different mouse models of HCC recapitulate distinct aspects of HCC biology, and their use should be adapted to specific questions based on the molecular features provided here. PMID- 30287487 TI - Native-state imaging of calcifying and noncalcifying microalgae reveals similarities in their calcium storage organelles. AB - Calcium storage organelles are common to all eukaryotic organisms and play a pivotal role in calcium signaling and cellular calcium homeostasis. In most organelles, the intraorganellar calcium concentrations rarely exceed micromolar levels. Acidic organelles called acidocalcisomes, which concentrate calcium into dense phases together with polyphosphates, are an exception. These organelles have been identified in diverse organisms, but, to date, only in cells that do not form calcium biominerals. Recently, a compartment storing molar levels of calcium together with phosphorous was discovered in an intracellularly calcifying alga, the coccolithophore Emiliania huxleyi, raising a possible connection between calcium storage organelles and calcite biomineralization. Here we used cryoimaging and cryospectroscopy techniques to investigate the anatomy and chemical composition of calcium storage organelles in their native state and at nanometer-scale resolution. We show that the dense calcium phase inside the calcium storage compartment of the calcifying coccolithophore Pleurochrysis carterae and the calcium phase stored in acidocalcisomes of the noncalcifying alga Chlamydomonas reinhardtii have common features. Our observations suggest that this strategy for concentrating calcium is a widespread trait and has been adapted for coccolith formation. The link we describe between acidocalcisomal calcium storage and calcium storage in coccolithophores implies that our physiological and molecular genetic understanding of acidocalcisomes could have relevance to the calcium pathway underlying coccolithophore calcification, offering a fresh entry point for mechanistic investigations on the adaptability of this process to changing oceanic conditions. PMID- 30287486 TI - Cbln2 and Cbln4 are expressed in distinct medial habenula-interpeduncular projections and contribute to different behavioral outputs. AB - Cerebellins are important neurexin ligands that remain incompletely understood. Two critical questions in particular remain unanswered: do different cerebellins perform distinct functions, and do these functions act in the initial establishment of synapses or in rendering nascent synapses capable of normal synaptic transmission? Here we show that in mice, Cbln2 and Cbln4 are expressed in the medial habenula (MHb) nucleus in different types of neurons that project to distinct target neurons in the interpeduncular nucleus. Conditional genetic deletion of Cbln2 in the MHb impaired synaptic transmission at Cbln2+ synapses in the interpeduncular neurons within 3 wk, but decreased synapse numbers only after 3 mo, suggesting a functional, but not a structural, requirement for Cbln2 in synapses formed by Cbln2-expressing neurons. In contrast, genetic deletions of Cbln4 in the MHb had no major effect on synaptic transmission or synapse numbers in interpeduncular target neurons. Nevertheless, MHb ablation of both Cbln2 and Cbln4 significantly impaired behavioral responses in mice, but affected different types of behaviors. Specifically, Cbln2 MHb deletions decreased spatial learning, as measured in the water T-maze, whereas Cbln4 MHb deletions increased anxiety levels, as monitored in the open field test and elevated plus maze. Thus, Cbln2 and Cbln4 are expressed in distinct MHb neurons that contribute to different behaviors. PMID- 30287489 TI - Evidence for Stabilizing Selection Driving Mutational Turnover of Short Motifs in the Eukaryotic Complementary Sex Determiner (Csd) Protein. AB - Short linear motifs (SLiMs) can play pivotal functional roles in proteins, such as targeting proteins to specific subcellular localizations, modulating the efficiency of translation and tagging proteins for degradation. Until recently we had little knowledge about SLiM evolution. Only a few amino acids in these motifs are functionally important, making them likely to evolve ex nihilo and suggesting that they can play key roles in protein evolution. Several reports now suggest that these motifs can appear and disappear while their function in the protein is preserved, a process sometimes referred to as "turnover". However, there has been a lack of specific experiments to determine whether independently evolved motifs do indeed have the same function, which would conclusively determine whether the process of turnover actually occurs. In this study, we experimentally detected evidence for such a mutational turnover process for nuclear localization signals (NLS) during the post-duplication divergence of the Complementary sex determiner (Csd) and Feminizer (Fem) proteins in the honeybee (Apis mellifera) lineage. Experiments on the nuclear transport activity of protein segments and those of the most recent common ancestor (MRCA) sequences revealed that three new NLS motifs evolved in the Csd protein during the post-duplication divergence while other NLS motifs were lost that existed before duplication. A screen for essential and newly evolved amino acids revealed that new motifs in the Csd protein evolved by one or two missense mutations coding for lysine. Amino acids that were predating the duplication were also essential in the acquisition of the C1 motif suggesting that the ex nihilo origin was constrained by preexisting amino acids in the physical proximity. Our data support a model in which stabilizing selection maintains the constancy of nuclear transport function but allowed mutational turnover of the encoding NLS motifs. PMID- 30287490 TI - Multiphasic effect of vinyl pyrrolidone polymers on amyloidogenesis, from macromolecular crowding to inhibition. AB - Deposition of misfolded amyloid polypeptides, associated with cell death, is the hallmark of many degenerative diseases (e.g. type II diabetes mellitus and Alzheimer's disease). In vivo, cellular and extracellular spaces are occupied by a high volume fraction of macromolecules. The resulting macromolecular crowding energetically affects reactions. Amyloidogenesis can either be promoted by macromolecular crowding through the excluded volume effect or inhibited due to a viscosity increase reducing kinetics. Macromolecular crowding can be mimicked in vitro by the addition of non-specific polymers, e.g. Ficoll, dextran and polyvinyl pyrrolidone (PVP), the latter being rarely used to study amyloid systems. We investigated the effect of PVP on amyloidogenesis of full-length human islet amyloid polypeptide (involved in type II diabetes) using fibrillisation and surface activity assays, ELISA, immunoblot and microscale thermophoresis. We demonstrate that high molecular mass PVP360 promotes amyloidogenesis due to volume exclusion and increase in effective amyloidogenic monomer concentration, like other crowders, but without the confounding effects of viscosity and surface activity. Interestingly, we also show that low molecular mass PVP10 has unique inhibitory properties as inhibition of fibril elongation occurs mainly in the bulk solution and is due to PVP10 directly and strongly interacting with amyloid species rather than the increase in viscosity typically associated with macromolecular crowding. In vivo, amyloidogenesis might be affected by the properties and proximity of endogenous macromolecular crowders, which could contribute to changes in associated pathogenesis. More generally, the PVP10 molecular backbone could be used to design small compounds as potential inhibitors of toxic species formation. PMID- 30287488 TI - Noncanonical autophagy at ER exit sites regulates procollagen turnover. AB - Type I collagen is the main component of bone matrix and other connective tissues. Rerouting of its procollagen precursor to a degradative pathway is crucial for osteoblast survival in pathologies involving excessive intracellular buildup of procollagen that is improperly folded and/or trafficked. What cellular mechanisms underlie this rerouting remains unclear. To study these mechanisms, we employed live-cell imaging and correlative light and electron microscopy (CLEM) to examine procollagen trafficking both in wild-type mouse osteoblasts and osteoblasts expressing a bone pathology-causing mutant procollagen. We found that although most procollagen molecules successfully trafficked through the secretory pathway in these cells, a subpopulation did not. The latter molecules appeared in numerous dispersed puncta colocalizing with COPII subunits, autophagy markers and ubiquitin machinery, with more puncta seen in mutant procollagen-expressing cells. Blocking endoplasmic reticulum exit site (ERES) formation suppressed the number of these puncta, suggesting they formed after procollagen entry into ERESs. The punctate structures containing procollagen, COPII, and autophagic markers did not move toward the Golgi but instead were relatively immobile. They appeared to be quickly engulfed by nearby lysosomes through a bafilomycin insensitive pathway. CLEM and fluorescence recovery after photobleaching experiments suggested engulfment occurred through a noncanonical form of autophagy resembling microautophagy of ERESs. Overall, our findings reveal that a subset of procollagen molecules is directed toward lysosomal degradation through an autophagic pathway originating at ERESs, providing a mechanism to remove excess procollagen from cells. PMID- 30287491 TI - Variants with increased negative electrostatic potential in the Cx50 gap junction pore increased unitary channel conductance and magnesium modulation. AB - Gap junction (GJ) channels are oligomers of connexins forming channels linking neighboring cells. GJs formed by different connexins show distinct unitary channel conductance (gammaj), transjunctional voltage-dependent gating (V j gating) properties, and modulation by intracellular magnesium ([Mg2+]i). The underlying molecular determinants are not fully clear. Previous experimental evidence indicates that residues in the amino terminal (NT) and initial segment of the first extracellular (E1) domain influence the gammaj, V j-gating, and/or [Mg2+]i modulation in several GJs. Increasing negatively charged residues in Cx50 (connexin50) E1 (G46D or G46E) increased gammaj, while increasing positively charged residue (G46K) reduced the gammaj Sequence alignment of Cx50 and Cx37 in the NT and E1 domains revealed that in Cx50 G8 and V53, positions are negatively charged residues in Cx37 (E8 and E53, respectively). To evaluate these residues together, we generated a triple variant in Cx50, G8E, G46E, and V53E simultaneously to study its gammaj, V j-gating properties, and modulation by [Mg2+]i Our data indicate that the triple variant and individual variants G8E, G46E, and V53E significantly increased Cx50 GJ gammaj without a significant change in the V j gating. In addition, elevated [Mg2+]i reduced gammaj in Cx50 and all the variant GJs. These results and our homology structural models suggest that these NT/E1 residues are likely to be pore-lining and the variants increased the negative electrostatic potentials along the GJ pore to facilitate the gammaj of this cation-preferring GJ channel. Our results indicate that electrostatic properties of the Cx50 GJ pore are important for the gammaj and the [Mg2+]i modulation. PMID- 30287492 TI - Structure-function studies of the asparaginyl-tRNA synthetase from Fasciola gigantica: understanding the role of catalytic and non-catalytic domains. AB - The asparaginyl-tRNA synthetase (NRS) catalyzes the attachment of asparagine to its cognate tRNA during translation. NRS first catalyzes the binding of Asn and ATP to form the NRS-asparaginyl adenylate complex, followed by the esterification of Asn to its tRNA. We investigated the role of constituent domains in regulating the structure and activity of Fasciola gigantica NRS (FgNRS). We cloned the full length FgNRS, along with its various truncated forms, expressed, and purified the corresponding proteins. Size exclusion chromatography indicated a role of the anticodon-binding domain (ABD) of FgNRS in protein dimerization. The N-terminal domain (NTD) was not essential for cognate tRNA binding, and the hinge region between the ABD and the C-terminal domain (CTD) was crucial for regulating the enzymatic activity. Molecular docking and fluorescence quenching experiments elucidated the binding affinities of the substrates to various domains. The molecular dynamics simulation of the modeled protein showed the presence of an unstructured region between the NTD and ABD that exhibited a large number of conformations over time, and further analysis indicated this region to be intrinsically disordered. The present study provides information on the structural and functional regulation, protein-substrate(s) interactions and dynamics, and the role of non-catalytic domains in regulating the activity of FgNRS.

PMID- 30287498 TI - A negative feedback loop between long noncoding RNA NBAT1 and Sox9 inhibits the malignant progression of gastric cancer cells. AB - Long noncoding RNAs (lncRNAs) play critical roles in carcinogenesis and progression, and act as important gene expression modulators. Recent evidence indicates that lncRNA neuroblastoma associated transcript 1 (NBAT1) functions as a tumor suppressor in some types of human cancers. However, its functional role in the development of gastric cancer (GC) remains unknown. The aim of this research was to investigate the clinical significance and biological functions of NBAT1 in GC. NBAT1 was found to be significantly down-regulated in GC tissue. Decreased NBAT1 expression was correlated with poor differentiation, higher tumor stage and lymph node metastasis, and poor prognosis. Functional assays showed that NBAT1 inhibited GC proliferation, migration, and invasion. NBAT1 also suppressed proliferation, migration, and capillary tube formation of human umbilical vein endothelial cells (HUVECs). Mechanistically, NBAT1 interacted with Sox9, and reduced its protein stability by promoting it from polyubiquitination and proteasome-dependent degradation. Moreover, we revealed that Sox9 could occupy the NBAT1 promoter to inactivate its transcription. The negative feedback loop of NBAT1 and Sox9 continuously enhanced the suppressive effects. In conclusion, these findings suggest that feedback regulation of NBAT1 and Sox9 served as a critical effector in GC progression. PMID- 30287499 TI - Effect of microRNA-495 on lower extremity deep vein thrombosis through the TLR4 signaling pathway by regulation of IL1R1. AB - Lower extremity deep vein thrombosis (LEDVT) a common peripheral vascular disease, caused by a blood clot in a deep vein is usually accompanied by swelling of the lower limbs. MicroRNAs (miRs) have been reported to play roles in LEDVT. We investigated the effect of miR-495 on LEDVT via TLR4 signaling pathway through IL1R1. LEDVT mouse model was established, and the femoral vein (FV) tissues were collected to detect expressions of miR-495, IL1R1, and TLR4 signaling-related genes. The expressions of both CD31 and CD34 (markers for endothelial progenitor cells) in the FV endothelial cells as well as the proportion of CD31+/CD34+ cells in peripheral blood were measured in order to evaluate thrombosis. The effect of miR-495 on cell viability, cell cycle, and apoptosis was analyzed. IL1R1 was confirmed as the target gene of miR-495. Besides, inhibiting the miR-495 expression could increase IL1R1 expression along with activating the TLR4 signaling pathway. The total number of the leukocytes along with the ratio of weight to length of thrombus in the FV tissue showed an increase. The overexpression of miR-495 could promote FV endothelial cell viability. By injecting agomiR-495 and antagomiR-495 in vivo, the number of leukocytes in the FV tissues and the ratio of weight to length of thrombus were significantly decreased in the mice injected with the overexpressed miR-495, and the IL1R1/TLR4 signaling pathway was inhibited. Collectively, overexpressed miR-495 directly promotes proliferation while simultaneously inhibiting apoptosis of FV endothelial cells, alleviating FV thrombosis by inhibiting IL1R1 via suppression of TLR4 signaling pathway.

PMID- 30287501 TI - Fangjing decoction relieves febrile seizures-induced hippocampal neuron apoptosis in rats via regulating the Akt/mTOR pathway. AB - Background: Fangjing decoction is a Traditional Chinese Medicine that exhibits anticonvulsive effects in treating febrile seizures (FS). Its action mechanism and the regulation on Akt/mammalian target of rapamycin (mTOR) pathway were revealed in the present study.Methods: FS model was established in Sprague-Dawley rats with or without Fangjing decoction treatment. On day 5, following initiation of drug treatment, seizures were monitored. Hippocampal neuron apoptosis was assessed using terminal dUTP nick end-labeling method. The levels of Bax, protein kinase B (Akt), phospho-Akt (p-Akt), mTOR, and p-mTOR proteins were analyzed using Western blotting. The content of hippocampal gamma-aminobutyric acid (GABA) was measured by using ELISA assay.Results: Compared with the control group (n=8), Fangjing decoction effectively shortened escape latency and duration of FS and decreased the frequency of FS in rats (n=8). Concomitantly, the apoptosis of hippocampal neurons, as well as Bax protein levels were also decreased in FS rats which were treated with Fangjing decoction. In addition, the Akt/mTOR signaling was found to be activated in rat hippocampus following FS, as evidenced by increased p-Akt and p-mTOR, while Fangjing decoction could inhibit the activation of Akt/mTOR signaling. Furthermore, the low GABA content in rat hippocampus following FS was significantly elevated by Fangjing decoction treatment. More importantly, SC79, a specific activator for Akt, apparently attenuated the protective effects of Fangjing decoction on FS rats.Conclusion: These results suggest that Fangjing decoction protects the hippocampal neurons from apoptosis by inactivating Akt/mTOR pathway, which may contribute to mitigating FS-induced brain injury. PMID- 30287502 TI - Metabolomic profiling of ovary in mice treated with FSH using ultra performance liquid chromatography/mass spectrometry. AB - The growth and development of follicles are a very complex physiological process that is regulated by endocrine, autocrine and paracrine mechanisms. The effect of small molecules in follicular microenvironment on follicular growth and development has not been clearly analyzed. In the present study, the metabolic changes in ovaries of FSH-stimulated mice were investigated. Metabolomic profiling of ovary stimulated by FSH were analyzed by ultra-performance liquid chromatography/mass spectrometry and characterized by principal components analysis and orthogonal partial least squares discriminant analysis. Multivariate statistical analysis identified 21 differentially metabolites in positive ion mode and 12 in negative ion mode in the FSH-treated mice compared with the control mice. These results indicated that various types of phosphatidylcholine were changed. Furthermore, the levels of L-Glutamyl 5-phosphate, N-Acetyl-L aspartic acid, 4-fumarylacetoacetic acid, adenylylselenate and 5' Methylthioadenosine in the ovaries of the FSH-stimulated mice were decreased. However, the levels of 19-hydroxytestosterone and 5,10-methenyltetrahydrofolic acid were significantly increased in the positive ion mode and negative ion mode, respectively. Thirty-three differential metabolites including fatty acid metabolism, amino acid metabolism and lipid metabolism in the ovaries of mice were affected by FSH injection. The findings of our study provide a new insight into understanding the follicular development. PMID- 30287503 TI - Zhenbao Pill reduces Treg cell proportion in acute spinal cord injury rats by regulating TUG1/miR-214/HSP27 axis. AB - Background: Acute spinal cord injury (SCI) is one of the weakest pathologies that seriously affect the quality of life of patients. Objective: To study the mechanism of how Zhenbao Pill reduces Treg cell proportion and improves acute SCI. Methods: A rat SCI model was established. Flow cytometry analysis was performed to determine the Treg cell proportion. RNA immunoprecipitation (RIP) and RNA pull-down were applied in confirming taurine up-regulated gene 1 (TUG1) and miR-214 binding. Intrathecal injection of TUG1 siRNA was also conducted to determine the effect of TUG1 in vivo Results: Zhenbao Pill promoted the expression of TUG1 and heat shock protein 27 (HSP27) protein, and reduced the expression of miR-214 and forkhead box protein p3 (Foxp3) as well as Treg cell proportion in a concentration-dependent manner in SCI rats or in vitro cultured CD4+ T cells. Knockdown of TUG1 reversed the high protein expression of HSP27 and the inhibition of Treg cell proportion as well as Foxp3 protein induced by Zhenbao Pill, and miR-214 inhibitor canceled the TUG1 knockdown effect. Further, miR-214 mimic reversed the inhibition of Treg cell proportion and Foxp3 protein expression by Zhenbao Pill, which was abolished by the overexpression of HSP27. The mechanism was validated in animal experiments. Conclusion: Zhenbao Pill regulated TUG1/miR-214/HSP27 signaling pathway to reduce Treg cell proportion and thus relieve acute SCI. PMID- 30287504 TI - lncRNA Gm15290 promotes cell proliferation and invasion in lung cancer through directly interacting with and suppressing the tumor suppressor miR-615-5p. AB - Long non-coding RNAs (lncRNAs) have been involved in occurrence and progression of multiple cancers. In the present study, we investigated the role of lncRNA Gm15290 in the proliferation and invasion of non-small cell lung cancer (NSCLC) cells. First, we found that lncRNA Gm15290 was markedly up-regulated in tumor tissues from NSCLC patients and NSCLC cell lines, compared with adjacent normal tissues and normal lung cell line HBE respectively. Then, different concentrations of pcDNA-Gm15290 expression vector and Gm15290 siRNA were respectively transfected into A549 NSCLC cells. Our results showed that overexpression of Gm15290 significantly increased the proliferation and invasion of A549 cells and suppressed cell apoptosis. Knockdown of Gm15290 suppressed A549 cell proliferation and invasion and promoted cell apoptosis. Subsequently, we explored the underlying mechanism through which Gm15290 promoted cell proliferation and invasion. The output of RNA hybrid bioinformatic tool revealed that Gm15290 potentially interacted with tumor suppressor miR-615-5p which displayed an opposite expression pattern in the cell lines and a strong negative correlation with the levels of Gm15290 in NSCLC patients (r2 = 0.9677, P<0.0001). The results of RNA pull-down assays confirmed that Gm15290 directly bound with miR-615-5p Gm15290 negatively regulated the expression of miR-615-5p and increased the protein levels of miR-615-5p target genes, including IGF2, AKT2, and SHMT2 Moreover, miR-615-5p mimic could antagonize the promoting effect of Gm15290 on cell proliferation and invasion.

AB - A common complication of both type I and type II diabetes is nephropathy, characterized by accumulation of extracellular matrix in the glomerular mesangium. This indicates a central role of mesangial cells in the pathophysiology of diabetic nephropathy. Using the proteomic approach, it was earlier elucidated in a rat model that the proteasome subunit-alpha type-6 protein (PSMA6) is suppressed in the renal cortex in nephropathic kidney. However, the underlying mechanism effecting suppression of PSMA6 protein in the renal cortex is not yet known. Twenty diabetic patients were enrolled and the expression level of PSMA6 in them was detected by immunohistochemistry. The protein and mRNA expression levels of PSMA6 in NRK-52E cells under high glucose condition were determined by Western blot and quantitative real-time PCR, respectively. Dual luciferase assay was used to detect the relationship of PSMA6 and miR-4490. Our results show that PSMA6 protein is down-regulated in patients with diabetic nephropathy compared with healthy control. Using the NRK-52E cell line cultured under high glucose condition as an in vitro model of diabetic nephropathy, we show that loss of PSMA6 protein expression occured independent of changes the in PSMA6 mRNA expression. We next elucidate that PSMA6 mRNA is post transcriptionally regulated by the microRNA (miRNA)-4490, whose expression is inversely correlated to PSMA6 protein expression. Using reporter assays we show that PSMA6 is a direct target of the miR-4490. Exogenous manipulation of miR-4490 levels modulated expression of PSMA6, indicating that miR-4490 can be tested as a biomarker for nephropathy in diabetic patients.

AB - Monocyclic monoterpenes have been recognized as useful pharmacological ingredients due to their ability to treat numerous diseases. Limonene and perillyl alcohol as well as their metabolites (especially perillic acid and its methyl ester) possess bioactivities such as antitumor, antiviral, anti inflammatory, and antibacterial agents. These therapeutic properties have been well documented. Based on the aforementioned biological properties of limonene and its metabolites, their structural modification and development into effective drugs could be rewarding. However, utilization of these monocyclic monoterpenes as scaffolds for the design and developments of more effective chemoprotective agents has not received the needed attention by medicinal scientists. Recently, some derivatives of limonene metabolites have been synthesized. Nonetheless, there have been no thorough studies on their pharmacokinetic and pharmacodynamic properties as well as their inhibition against isoprenylation enzymes. In this review, recent research progress in the biochemical significance of limonene and its metabolites was summarized with emphasis on their antitumor effects. Future prospects of these bioactive monoterpenes for drug design and development are also highlighted. PMID- 30287509 TI - Mitochondrial diseases caused by dysfunctional mitochondrial protein import. AB - Mitochondria are essential organelles which perform complex and varied functions within eukaryotic cells. Maintenance of mitochondrial health and functionality is thus a key cellular priority and relies on the organelle's extensive proteome. The mitochondrial proteome is largely encoded by nuclear genes, and mitochondrial proteins must be sorted to the correct mitochondrial sub-compartment post translationally. This essential process is carried out by multimeric and dynamic translocation and sorting machineries, which can be found in all four mitochondrial compartments. Interestingly, advances in the diagnosis of genetic disease have revealed that mutations in various components of the human import machinery can cause mitochondrial disease, a heterogenous and often severe collection of disorders associated with energy generation defects and a multisystem presentation often affecting the cardiovascular and nervous systems. Here, we review our current understanding of mitochondrial protein import systems in human cells and the molecular basis of mitochondrial diseases caused by defects in these pathways. PMID- 30287510 TI - Post-translational modification of nucleoid-associated proteins: an extra layer of functional modulation in bacteria? AB - Post-translational modification (PTM) of histones has been investigated in eukaryotes for years, revealing its widespread occurrence and functional importance. Many PTMs affect chromatin folding and gene activity. Only recently the occurrence of such modifications has been recognized in bacteria. However, it is unclear whether PTM of the bacterial counterparts of eukaryotic histones, nucleoid-associated proteins (NAPs), bears a comparable significance. Here, we scrutinize proteome mass spectrometry data for PTMs of the four most abundantly present NAPs in Escherichia coli (H-NS, HU, IHF and FIS). This approach allowed us to identify a total of 101 unique PTMs in the 11 independent proteomic studies covered in this review. Combined with structural and genetic information on these proteins, we describe potential effects of these modifications (perturbed DNA binding, structural integrity or interaction with other proteins) on their function. PMID- 30287508 TI - RAS variant signalling. AB - RAS proteins are small GTPases that regulate signalling networks that control cellular proliferation and survival. They are frequently mutated in cancer and a commonly occurring group of developmental disorders called RASopathies. We discuss recent findings describing how RAS isoforms and different activating mutations differentially contribute to normal and disease-associated biology and the mechanisms that have been proposed to underpin this.

Beadle Award honors individuals who have made outstanding contributions to the community of genetics researchers and who exemplify the qualities of its namesake. For his work fostering communication and collaboration among members of the many subfields of genetics, Philip Hieter of the University of British Columbia has been named 2018's recipient of the award. Among his contributions are many initiatives that aim to better link human and model organism geneticists, including the Canadian Rare Diseases Models and Mechanisms Network-a consortium that connects investigators who identify rare disease genes in humans to basic scientists who can study the genes in model organisms. PMID- 30287511 TI - Carcinogens and DNA damage. AB - Humans are variously and continuously exposed to a wide range of different DNA damaging agents, some of which are classed as carcinogens. DNA damage can arise from exposure to exogenous agents, but damage from endogenous processes is probably far more prevalent. That said, epidemiological studies of migrant populations from regions of low cancer risk to high cancer risk countries point to a role for environmental and/or lifestyle factors playing a pivotal part in cancer aetiology. One might reasonably surmise from this that carcinogens found in our environment or diet are culpable. Exposure to carcinogens is associated with various forms of DNA damage such as single-stand breaks, double-strand breaks, covalently bound chemical DNA adducts, oxidative-induced lesions and DNA DNA or DNA-protein cross-links. This review predominantly concentrates on DNA damage induced by the following carcinogens: polycyclic aromatic hydrocarbons, heterocyclic aromatic amines, mycotoxins, ultraviolet light, ionising radiation, aristolochic acid, nitrosamines and particulate matter. Additionally, we allude to some of the cancer types where there is molecular epidemiological evidence that these agents are aetiological risk factors. The complex role that carcinogens play in the pathophysiology of cancer development remains obscure, but DNA damage remains pivotal to this process. PMID- 30287513 TI - How Mendel's Interest in Inheritance Grew out of Plant Improvement. AB - Despite the fact that Gregor Mendel is generally respected as the founder of genetics, little is known about the origin of and motivation for his revolutionary work. No primary sources are known that discuss his work during the period of his pea crossing experiments. Here, we report on two previously unknown interconnected local newspaper articles about Mendel's work that predate his famous Pisum lectures by 4 years. These articles describe Mendel as a plant breeder and a horticulturist. We argue that Mendel's initial interests concerned crop improvement, but that with time he became more interested in fundamental questions about inheritance, fertilization, and natural hybridization.

PMID- 30287519 TI - Omega-3 polyunsaturated fatty acids reduce preterm labor by inhibiting trophoblast cathepsin S and inflammasome activation. AB - Preterm labor is associated with inflammation and infection. The mechanisms underlying the role of omega-3 fatty acid in inflammasome activation and prevention of preterm labor remain unknown. We hypothesized that omega-3 fatty acid can reduce the rate of preterm birth induced by infection and trophoblast inflammation. In the present study, we found that inflammasome-related molecules and IL-1beta in trophoblasts were activated by TNF-alpha derived from lipopolysaccharide (LPS)-stimulated THP-1 cell-conditioned medium (CM) and recombinant TNF-alpha protein. The results demonstrated that stimulation with TNF alpha caused lysosomal rupture in trophoblasts, which accelerated cathepsin S (CTSS) diffusion from lysosomes to the cytosol and activated NLRP1 (nacht domain leucine-rich repeat, and pyd-containing protein 1) and absent in melanoma 2 (AIM2) inflammasomes, thereby increasing IL-1beta secretion. Moreover, in response to LPS challenge, TNF-alpha increased trophoblast cell death and decreased cell viability through inflammasome and CTSS activation. Stearidonic acid (SDA; 18:4n-3) and docosahexaenoic acid (DHA; 22:6n-3) inhibited inflammasome-related molecule synthesis and CTSS and caspase-1 activation, which further reduced the preterm delivery rate of pregnant mice induced by LPS (92.9 compared with 69.7% (DHA); 92.9 compared with 53.5% (SDA)). Higher expression of TNF-alpha, IL-1beta, prostaglandin E2, and CTSS, but lower resolvin D1 expression, was observed in preterm pregnant mice than in controls. Similarly, resolvin D1 was highly expressed in women with term delivery compared with women with preterm delivery. Thus, SDA and DHA may attenuate macrophage-derived TNF alpha inducing CTSS and inflammasome activation, IL-1beta secretion, and placental trophoblast cell death. These functions are implicated in the preventive effects of SDA and DHA on preterm labor. PMID- 30287518 TI - Association of Soluble TNFR-1 Concentrations with Long-Term Decline in Kidney Function: The Multi-Ethnic Study of Atherosclerosis. AB - BACKGROUND: TNF receptor-1 (TNFR-1), which plays a causative role in endothelial cell dysfunction and inflammation, is expressed on the cell surface in glomerular and peritubular capillary endothelium of the kidneys. Higher soluble TNF receptor 1 (sTNFR-1) concentrations are associated with kidney disease progression among persons with established diabetic kidney disease. However, no studies have assessed sTNFR-1's role in long-term kidney function changes in a multiethnic population without cardiovascular disease at baseline. METHODS: We tested associations between baseline sTNFR-1 concentrations and 10-year decline in eGFR (incident >=40% decline and annual proportional decline) among 2548 participants in the Multi-Ethnic Study of Atherosclerosis (MESA), a prospective cohort study. Serum creatinine concentrations were determined at enrollment and study years 3, 5, and 10. RESULTS: Mean age of participants was 61 years old, 53% were women, and mean baseline eGFR was 79 ml/min per 1.73 m2. Serum sTNFR-1 was inversely associated with baseline eGFR. Over median follow-up of 9.3 years, 110 participants developed >=40% decline in eGFR; each SD higher concentration of sTNFR1 was associated with higher risk of 40% eGFR decline (adjusted hazard ratio, 1.43; 95% confidence interval [95% CI], 1.16 to 1.77; P<0.001). The highest sTNFR-1 tertile was associated with adjusted annualized decline in eGFR of 1.94% (95% CI, 1.79 to 2.09). Associations persisted across subgroups defined by demographics, hypertension, diabetes, and baseline CKD status. CONCLUSIONS: Elevated serum sTNFR-1 concentrations are associated with faster declines in eGFR over the course of a decade in a multiethnic population, independent of previously known risk factors for kidney disease progression. PMID- 30287520 TI - Early isolated V-lesion may not truly represent rejection of the kidney allograft. AB - Intimal arteritis is known to be a negative prognostic factor for kidney allograft survival. Isolated v-lesion (IV) is defined as intimal arteritis with minimal tubulointerstitial inflammation (TI). Although the Banff classification assesses IV as T cell-mediated rejection (TCMR), clinical, and prognostic significance of early IV (early IV, eIV) with negative C4d and donor-specific antibodies (DSA) remains unclear. To help resolve if such eIV truly represents acute rejection, a molecular study was performed. The transcriptome of eIV (n=6), T cell-mediated vascular rejection with rich TI (T cell-mediated vascular rejection, TCMRV, n=4) and non-rejection histologic findings (n=8) was compared using microarrays. A total of 310 genes were identified to be deregulated in TCMRV compared with eIV. Gene enrichment analysis categorized deregulated genes to be associated primarily with T-cells associated biological processes involved in an innate and adaptive immune and inflammatory response. Comparison of deregulated gene lists between the study groups and controls showed only a 1.7% gene overlap. Unsupervised hierarchical cluster analysis revealed clear distinction of eIV from TCMRV and showed similarity with a control group. Up regulation of immune response genes in TCMRV was validated using RT-qPCR in a different set of eIV (n=12) and TCMRV (n=8) samples. The transcriptome of early IV (< 1 month) with negative C4d and DSA is associated with a weak immune signature compared with TCMRV and shows similarity with normal findings. Such eIV may feature non-rejection origin and reflect an injury distinct from an alloimmune response. The present study supports use of molecular methods when interpreting kidney allograft biopsy findings. PMID- 30287521 TI - Raised intracranial pressure in those presenting with headache. PMID- 30287522 TI - Evidence for Chemopreventive and Resilience Activity of Licorice: Glycyrrhiza Glabra and G. Inflata Extracts Modulate Estrogen Metabolism in ACI Rats. AB - Women are increasingly using botanical dietary supplements (BDS) to reduce menopausal hot flashes. Although licorice (Glycyrrhiza sp.) is one of the frequently used ingredients in BDS, the exact plant species is often not identified. We previously showed that in breast epithelial cells (MCF-10A), Glycyrrhiza glabra (GG) and G. inflata (GI), and their compounds differentially modulated P450 1A1 and P450 1B1 gene expression, which are responsible for estrogen detoxification and genotoxicity, respectively. GG and isoliquiritigenin (LigC) increased CYP1A1, whereas GI and its marker compound, licochalcone A (LicA), decreased CYP1A1 and CYP1B1 The objective of this study was to determine the distribution of the bioactive licorice compounds, the metabolism of LicA, and whether GG, GI, and/or pure LicA modulate NAD(P)H quinone oxidoreductase (NQO1) in an ACI rat model. In addition, the effect of licorice extracts and compounds on biomarkers of estrogen chemoprevention (CYP1A1) as well as carcinogenesis (CYP1B1) was studied. LicA was extensively glucuronidated and formed GSH adducts; however, free LicA as well as LigC were bioavailable in target tissues after oral intake of licorice extracts. GG, GI, and LicA caused induction of NQO1 activity in the liver. In mammary tissue, GI increased CYP1A1 and decreased CYP1B1, whereas GG only increased CYP1A1 LigC may have contributed to the upregulation of CYP1A1 after GG and GI administration. In contrast, LicA was responsible for GI mediated downregulation of CYP1B1 These studies highlight the polypharmacologic nature of botanicals and the importance of standardization of licorice BDS to specific Glycyrrhiza species and to multiple constituents.

AB - Duvelisib (also known as IPI-145) is an oral, dual inhibitor of phosphatidylinositol 3-kinase delta and gamma (PI3K-delta,gamma) being developed for treatment of hematologic malignancies. PI3K-delta,gamma signaling can promote B-cell proliferation and survival in clonal B-cell malignancies, such as chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). In a phase 1 study, duvelisib showed clinically meaningful activity and acceptable safety in CLL/SLL patients. We report here the results of DUO, a global phase 3 randomized study of duvelisib vs ofatumumab monotherapy for patients with relapsed or refractory (RR) CLL/SLL. Patients were randomized 1:1 to oral duvelisib 25 mg twice daily (n = 160) or ofatumumab IV (n = 159). The study met the primary study end point by significantly improving progression-free survival per independent review committee assessment compared with ofatumumab for all patients (median, 13.3 months vs 9.9 months; hazard ratio [HR] = 0.52; P < .0001), including those with high-risk chromosome 17p13.1 deletions [del(17p)] and/or TP53 mutations (HR = 0.40; P = .0002). The overall response rate was significantly higher with duvelisib (74% vs 45%; P < .0001) regardless of del(17p) status. The most common adverse events were diarrhea, neutropenia, pyrexia, nausea, anemia, and cough on the duvelisib arm, and neutropenia and infusion reactions on the ofatumumab arm. The DUO trial data support duvelisib as a potentially effective treatment option for patients with RR CLL/SLL. This trial was registered at www.clinicaltrials.gov as #NCT02004522.

PMID- 30287524 TI - Nuclear Phospholipase C isoenzyme imbalance leads to pathologies in brain, hematologic, neuromuscular and fertility disorders. AB - Phosphoinositide-specific PLC (PI-PLCs) are involved in signaling pathways related to critical cellular functions, such as cell cycle regulation, cell differentiation, and gene expression. PI-PLCs are highly expressed in different brain areas, and nuclear PI-PLCs have been studied as key enzymes, molecular targets, and clinical prognostic/diagnostic factors in many physiopathologic processes. Here, we summarize the main studies about nuclear PI-PLCs, specifically the imbalance of isozymes such as PI-PLCbeta1 and PI-PLCzeta, in cerebral, hematologic, neuromuscular, and fertility disorders. PI-PLCbeta1 and PI PLCgamma1 affect epilepsy, depression, and bipolar disorder. In the brain, PI PLCbeta1 is involved in endocannabinoid neuronal excitability and is a potentially novel signature gene for subtypes of high-grade glioma. An altered quality or quantity of PI-PLCzeta contributes to sperm defects that result in infertility, and PI-PLCbeta1 aberrant inositide signaling contributes to both hematologic and degenerative muscle diseases. Understanding the mechanisms behind PI-PLC involvement in human pathologies may help identify new strategies for personalized therapies of these conditions. PMID- 30287514 TI - Anatomy and Physiology of the Digestive Tract of Drosophila melanogaster. AB - The gastrointestinal tract has recently come to the forefront of multiple research fields. It is now recognized as a major source of signals modulating food intake, insulin secretion and energy balance. It is also a key player in immunity and, through its interaction with microbiota, can shape our physiology and behavior in complex and sometimes unexpected ways. The insect intestine had remained, by comparison, relatively unexplored until the identification of adult somatic stem cells in the Drosophila intestine over a decade ago. Since then, a growing scientific community has exploited the genetic amenability of this insect organ in powerful and creative ways. By doing so, we have shed light on a broad range of biological questions revolving around stem cells and their niches, interorgan signaling and immunity. Despite their relatively recent discovery, some of the mechanisms active in the intestine of flies have already been shown to be more widely applicable to other gastrointestinal systems, and may therefore become relevant in the context of human pathologies such as gastrointestinal cancers, aging, or obesity. This review summarizes our current knowledge of both the formation and function of the Drosophila melanogaster digestive tract, with a major focus on its main digestive/absorptive portion: the strikingly adaptable adult midgut.

AB - Since the earliest days of research on nematodes, scientists have noted the developmental and morphological variation that exists within and between species. As various cellular and developmental processes were revealed through intense focus on Caenorhabditis elegans, these comparative studies have expanded. Within the genus Caenorhabditis, they include characterization of intraspecific polymorphisms and comparisons of distinct species, all generally amenable to the same laboratory culture methods and supported by robust genomic and experimental tools. The C. elegans paradigm has also motivated studies with more distantly related nematodes and animals. Combined with improved phylogenies, this work has led to important insights about the evolution of nematode development. First, while many aspects of C. elegans development are representative of Caenorhabditis, and of terrestrial nematodes more generally, others vary in ways both obvious and cryptic. Second, the system has revealed several clear examples of developmental flexibility in achieving a particular trait. This includes developmental system drift, in which the developmental control of homologous traits has diverged in different lineages, and cases of convergent evolution. Overall, the wealth of information and experimental techniques developed in C. elegans is being leveraged to make nematodes a powerful system for evolutionary cellular and developmental biology. PMID- 30287527 TI - Client Perceptions of Quality and Choice at Static, Mobile Outreach, and Special Family Planning Day Services in 3 African Countries. AB - BACKGROUND: Use of long-acting reversible contraceptives (LARCs) has grown rapidly in the Democratic Republic of the Congo (DRC), Tanzania, and Uganda. Uptake of LARCs is particularly high during mobile outreach and special family planning day events. It is therefore important to examine client perceptions of and experiences with full, free, and informed choice (FFIC) in different service delivery modalities. METHODS: Between April and July 2015, we conducted a cross sectional family planning client survey to assess FFIC and client satisfaction at static, mobile outreach, and special family planning day services in the DRC (n=9 sites), Tanzania (n=13), and Uganda (n=8). The study investigated clients' perceptions across 13 elements of FFIC, including measures of the quality of counseling and respondent satisfaction with services across the service delivery approaches. Composite FFIC scores were constructed and analyzed as the proportion of women who reported affirmatively to all elements and the mean score of positive responses. Satisfaction was assessed using a 4-point Likert scale. We used logistic regression to assess the association between the primary outcomes and mode of service delivery. RESULTS: In total, we interviewed 585 women (n=150 in Uganda, n=200 in Tanzania, and n=235 in the DRC). The large majority of clients in all countries and modalities received their method of choice. Clients of mobile outreach and special family planning days preferred LARCs and permanent methods, particularly implants, compared with clients at static services. Composite measures of FFIC were lower for mobile outreach than for static services in Tanzania among all family planning clients (odds ratio [OR]=0.5; P<=.001) and among LARC clients specifically (OR=0.5; P<=.01); no significant differences were found in the DRC or Uganda. A mean FFIC score among all family planning clients showed that clients in all modalities in all countries reported experiencing most elements of FFIC, with averages ranging from 4.8 to 6.1 of 7 elements. Among LARC clients specifically, mean scores ranged from 8.3 to 9.8 of 11 elements. Where greater proportions of clients experienced higher FFIC, greater proportions of clients also tended to report being "very satisfied" with aspects of services and counseling. CONCLUSIONS: The results underscore that special family planning days and mobile outreach services are important and viable ways to increase women's access to family planning services, notably to LARCs, but further attention to respecting and fulfilling clients' full, free, and informed choice across all service delivery modalities is required. PMID- 30287528 TI - Quality and Cost Interventions During the Extended Perinatal Period to Increase Family Planning Use in Kinshasa, DRC: Results From an Initial Study. AB - BACKGROUND: Most women worldwide do not desire another pregnancy within a year after giving birth, but uptake of modern contraception during this time period is low. We independently tested 2 approaches to increasing contraceptive uptake and the 2 approaches combined using a quasi-experimental study design in Kinshasa, the Democratic Republic of the Congo. METHODS: The primary analytic data came from client exit interviews conducted post-intervention (N=563) from 4 study groups. The first arm (n=150) received free family planning, and the second arm (n=113) a quality inputs intervention involving systematic screening, referral, and immediate provision of long-acting reversible contraceptives (LARCs) after labor and delivery. The third arm (n=150) received a combination of the 2 interventions, and the fourth (n=150) no intervention. Family planning service statistics were also collected throughout the intervention period. RESULTS: Women in the quality arm (odds ratio [OR]=4.5; 95% confidence interval [CI], 1.8 to 10.9) and free/quality arm (OR=6.7; 95% CI, 2.8 to 16.1) were more likely to be properly screened for family planning than women in the control group, but paper referral was seldom implemented in any group. Women in the free arm (OR=3.8; 95% CI, 1.6 to 9.0) and in the free/quality arm (OR=11.0; 95% CI, 4.3 to 27.9) were more likely than the control group to report being properly counseled on family planning. Clients were more likely to be modern contraceptive users (excluding condoms) in the free arm (OR=3.2; 95% CI, 1.4 to 7.2) and in the free/quality arm (OR=8.6; 95% CI, 3.9 to 19.0) than in the control group. Clients in all study arms were more likely to use a LARC compared with the control group (Quality arm: OR=2.9; 95% CI, 1.1 to 7.9. Free arm: OR=5.6; 95% CI, 2.3 to 13.7. Free/quality arm: OR=8.4; 95% CI, 3.4 to 20.6). Service statistics from the combined intervention arm showed that a significantly greater proportion of family planning adoption occurred within the immediate postpartum period (0 to 2 days) in the quality arm (P<.001) and free/quality arm (P<.001) than in the control arm. Quality inputs, free contraceptives, and the combined intervention had positive impacts on aspects of screening and contraceptive uptake. The combined intervention performed best by all measures. CONCLUSION: Providing family planning, including LARCs, in the immediate postpartum period, implementing a systematic screening and referral system, and providing free methods may improve family planning access and uptake in the extended perinatal period in this environment. PMID- 30287530 TI - Global Health Competency Self-Confidence Scale: Tool Development and Validation. AB - BACKGROUND: Global health education in tertiary institutions worldwide is at an all-time high. Until recently, most evaluations of student learning from a global exposure was in the form of a reflective paper with little information that would enable standardized assessment of the competencies gained. In 2015, the Consortium of Universities for Global Health (CUGH) published a set of interprofessional global health competencies that were drawn upon to create a Global Health Competency Self-Confidence Scale and workbook. This study reports the development and validation of the scale and its implications for global health education. METHODS: In total, 126 graduate students from a university in New York State participated in the validation process of the Global Health Competency Self-Confidence Scale-an 11-domain, 22-item competency self-assessment to measure the level of confidence of students before and after undertaking a global learning experience. The team used factor analysis to compare the scale to the Global Health Competency Survey for content validity and reliability. RESULTS: Reliability and validity of the scale was determined. An exploratory factor analysis identified 4 standalone components as: (1) Ethical and Professional Practice, (2) Capacity Strengthening and Planning, (3) Structural and Social Determinants of Health, and (4) Strategic Analysis. The scale showed excellent internal consistency (Cronbach's alpha=0.92) and test-retest reliability (reliability (r)=0.455; P<.001). Concurrent validity was established. CONCLUSION: The Global Health Competency Self-Confidence Scale contributes to a further consolidation and refinement of competency groupings into components of global health education and offers a scale to assess student learning in global placements. PMID- 30287529 TI - Role of Religious Leaders in Promoting Contraceptive Use in Nigeria: Evidence From the Nigerian Urban Reproductive Health Initiative. AB - BACKGROUND: Despite the many supply- and demand-side interventions aimed at increasing contraceptive uptake, the modern contraceptive prevalence rate in Nigeria has remained very low (9.8%). Religion is an important part of the sociocultural fabric of many communities. As such, religious leaders have the power to inhibit or facilitate effective adoption of contraceptive methods to support family health. We assess the association of exposure to religious leaders' tailored scriptural family planning messages with contraceptive use in Nigeria. METHODS: This cross-sectional study used data from a Measurement, Learning and Evaluation Project survey conducted in 2015 in 4 Nigerian states Federal Capital Territory, Kaduna, Kwara, and Oyo. The final study sample was restricted to 9,725 non-pregnant women aged 15 to 49 years. Data analysis included descriptive statistics and binary logistic regression analysis to explore significant relationships between current use of a modern contraceptive method, exposure to family planning messages from religious leaders, and selected background characteristics. RESULTS: About 2 in 5 women reported being exposed to family planning messages from religious leaders in the past year. Bivariate results revealed a higher uptake of modern contraceptives among women with high exposure to different NURHI interventions (35.5%) compared with respondents in the low or medium exposure categories (14.5% and 24.5%, respectively). The multivariable analysis revealed significantly higher contraceptive uptake among women who had exposure to family planning messages from religious leaders relative to those with no exposure (odds ratio=1.70; 95% confidence interval, 1.54 to 1.87; P<.001). This association remained significant after adjustment for background characteristics and other selected variables. CONCLUSION: Interventions that engage clerics of different faiths as change agents for shaping norms and informing behaviors about family planning and contraceptive use are crucial for increasing contraceptive uptake in Nigeria. PMID- 30287532 TI - Childbirth and Early Newborn Care Practices in 4 Provinces in China: A Comparison With WHO Recommendations. AB - OBJECTIVES: As a part of the process of implementing Early Essential Newborn Care (EENC) in China, which are evidence-based interventions recommended by the World Health Organization (WHO), we sought to understand whether current hospital policies are consistent with WHO-recommended standards and what factors influence their use. Data from the study will help inform policy changes needed to support the introduction of evidence-based childbirth and early newborn care practices effectively and to inform further scale up of EENC nationwide. METHODS: Ten randomly selected hospitals in 4 early-introducing provinces participated in the study. We collected data from 20 simulated delivery scenario observations and focus group discussions and individual interviews with 10 hospital management staff. Policies, protocols, and guidelines related to childbirth and newborn care practice were also collected and reviewed at each hospital. Additionally, a survey was emailed to 15 childbirth and newborn experts from the 4 selected provinces and completed by 13. Data were compared with WHO EENC evidence-based standards to calculate the agreement rates. Barriers to introducing evidence based guidelines were identified in focus groups and key informant interviews, then combined into common categories. FINDINGS: Hospital policies were not consistent with WHO recommendations in 10 (59%) of the 17 delivery and early newborn care practices. Delayed cord clamping was recommended by 30% of hospital protocols and prolonged skin-to-skin contact by 13%, neither of which were observed in the delivery simulations. Kangaroo mother care (KMC) for stable preterm babies was required in only 17% of the hospitals; no preterm babies had KMC initiated, with all immediately separated from their mothers and admitted to neonatal intensive care units. Newborn resuscitation equipment was required to be placed within 2 meters of the delivery bed in 84% of hospital protocols, but was prepared in only 40% of cases. Immediate drying after birth was required in 48% of hospital protocols, but was initiated in only 20% of observed cases. CONCLUSIONS: Current childbirth and early newborn care policy and practice in China is not aligned with WHO recommendations for some major interventions. To make it easier and safer for hospital workers to practice EENC, expert working groups and national policies must be established to address inconsistencies and cultural beliefs and provide a strong, evidence-based set of guidelines for hospitals and health workers to follow.

AB - BACKGROUND: Helping Babies Breathe (HBB), a skills-based program in neonatal resuscitation for birth attendants in resource-limited settings, has been implemented in over 80 countries since 2010. Implementation studies of HBB incorporating low-dose high-frequency practice and quality improvement show substantial reductions in fresh stillbirth and first-day neonatal mortality. Revision of the program aimed to further augment provider and facilitator skills and address gaps in implementation with the goal of improving neonatal survival. METHODS: The Utstein Formula for Survival-Medical Science X Educational Efficiency X Local Implementation = Survival-provided a framework for the revisions. The 2015 Neonatal Resuscitation Consensus on Science and Treatment Recommendations by the International Liaison Committee on Resuscitation informed scientific updates, which were harmonized with the 2012 World Health Organization Basic Newborn Resuscitation Guidelines. Published literature and program reports, consensus guidelines on reprocessing equipment, systematic collection of suggestions from frontline users, and responses to a semistructured online questionnaire informed educational/implementation revisions. Links to maternal care were added. Draft materials underwent Delphi review and field testing in India and Sierra Leone. An Utstein-style meeting of stakeholders identified key actions for successful implementation. RESULTS: Scientific revisions included expectant management of infants with meconium-stained amniotic fluid, limitation of suctioning, and initiating and continuing effective ventilation until spontaneous respirations. Frontline users (N=102) suggested augmented simulation methods to build confidence and competence and additional guidance for facilitators on implementation. Users identified a need for sufficient practice during the workshop, systematized ongoing practice, and enough simulators for participants. Field trials refined approaches to self-reflection, feedback and debriefing, and quality improvement. Utstein meeting stakeholders validated the importance of quality improvement and use of data to improve outcomes. CONCLUSIONS: The second edition of HBB provides a newer paradigm of learning for providers that incorporates workshop practice, self-reflection, and feedback and debriefing to reinforce learning as well as the promotion of mentorship and development of facilitators, systems for low-dose high-frequency practice in facilities, and quality improvement related to neonatal resuscitation.

AB - From 2006 to 2014, Supply Chain Management System (SCMS), the global procurement and distribution project for the U.S. President's Emergency Plan for AIDS Relief (PEPFAR), distributed over US$1.6 billion worth of antiretroviral drugs and other health commodities, with over US$263 million purchased from local vendors in 14 countries in sub-Saharan Africa. A simple framework was developed and 39 local suppliers from 4 countries were interviewed between 2013 and 2014 to understand how SCMS local sourcing impacted supplier development. SCMS local suppliers reported new contracts with other businesses (77%), new assets acquired (67%), increased access to capital from local lending institutions (75%), offering more products and services (92%), and ability to negotiate better prices from their principles (80%). Additionally, 70% (n=27) of the businesses hired between 1 and 30 new employees after receiving their first SCMS contract and 15% (n=6) hired between 30 and 100 new employees. This study offers preliminary guidance on how bilateral and multilateral agencies could design effective local sourcing programs to create sustainable local markets for selected pharmaceutical products, laboratory, and transport services.

AB - BACKGROUND: Bangladesh is a highly populous country where the prevalence of drug resistant tuberculosis (DR-TB) is growing. With the rapid increase in DR-TB notifications through GeneXpert technology, it was imperative to come up with a new treatment strategy that could keep up with the increase of patients diagnosed. INTERVENTION: Intervention was designed to support national transition of DR-TB management of World Health Organization-approved long course (20-to-24 month regimen) treatment from a hospital-based approach to the decentralized model of community-based programmatic management of DR-TB (cPMDT). In close coordination with the Ministry of Health and Family Welfare and National TB Program, patients were initiated into treatment at hospitals and then transferred to community-based care. A cadre of directly observed therapy providers supported treatment at the household level, supervised by the outpatient DR-TB teams. METHODS: We conducted a descriptive pre- and post-intervention study of all 1,946 DR-TB patients enrolled in treatment nationwide between May 2012 and June 2015. Data were collected from hospitals, patient cards, district records, and diagnostic laboratories through the National TB Program. Intervention results were assessed in comparison with the baseline (2011) indicators. RESULTS: During the intervention period, treatment enrollment of 1,946 diagnosed DR-TB patients through the national program increased from 50% in 2011 to 100% in 2015. The delay between diagnosis and treatment initiation decreased from 69 days in 2011 to 6 days in 2014. Most (95%) of the patients completed all scheduled follow-up smear and culture tests. By the sixth month of treatment, 99% of patients had negative smear conversion and 98% had negative culture conversion. The treatment success rate increased from 70% in 2011 to 76% in 2015 at the end of the intervention period. The results also indicate a decline between baseline and end line from 34% to 9% for patients died, 34% to 10% for loss to follow-up, and 1.7% to 0% for treatment failure. CONCLUSIONS: Community-based management is an effective approach for increasing access to quality-assured DR-TB treatment. Using existing structures and resources, the intervention demonstrated that favorable treatment outcomes can be achieved and sustained by treating patients with DR-TB at their homes.

AB - Seminal fluid contains some of the fastest evolving proteins currently known. These seminal fluid proteins (Sfps) play crucial roles in reproduction, such as supporting sperm function, and particularly in insects, modifying female physiology and behaviour. Identification of Sfps in small animals is challenging, and often relies on samples taken from the female reproductive tract after mating. A key pitfall of this method is that it might miss Sfps that are of low abundance due to dilution in the female-derived sample or rapid processing in females. Here we present a new and complementary method, which provides added sensitivity to Sfp identification. We applied label-free quantitative proteomics to Drosophila melanogaster male reproductive tissue - where Sfps are unprocessed, and highly abundant - and quantified Sfps before and immediately after mating, to infer those transferred during copulation. We also analysed female reproductive tracts immediately before and after copulation to confirm the presence and abundance of known and candidate Sfps, where possible. Results were cross referenced with transcriptomic and sequence databases to improve confidence in Sfp detection. Our data were consistent with 125 previously reported Sfps. We found nine high-confidence novel candidate Sfps, which were both depleted in mated versus unmated males and identified within the reproductive tract of mated but not virgin females. We also identified 42 more candidates that are likely Sfps based on their abundance, known expression and predicted characteristics, and revealed that four proteins previously identified as Sfps are at best minor contributors to the ejaculate. The estimated copy numbers for our candidate Sfps were lower than for previously identified Sfps, supporting the idea that our technique provides a deeper analysis of the Sfp proteome than previous studies. Our results demonstrate a novel, high-sensitivity approach to the analysis of seminal fluid proteomes, whose application will further our understanding of reproductive biology. PMID- 30287547 TI - Validation of the 12-gene Predictive Signature for Adjuvant Chemotherapy Response in Lung Cancer. AB - Purpose: Response to adjuvant chemotherapy after tumor resection varies widely among patients with non-small cell lung cancer (NSCLC); therefore, it is of clinical importance to prospectively predict who will benefit from adjuvant chemotherapy before starting the treatment. The goal of this study is to validate a 12-gene adjuvant chemotherapy predictive signature developed from a previous study using a clinical-grade assay.Experimental Design: We developed a clinical grade assay for formalin-fixed, paraffin-embedded (FFPE) samples using the NanoString nCounter platform to measure the mRNA expression of the previously published 12-gene set. The predictive performance was validated in a cohort of 207 patients with early-stage resected NSCLC with matched propensity score of adjuvant chemotherapy.Results: The effects of adjuvant chemotherapy were significantly different in patients from the predicted adjuvant chemotherapy benefit group and those in the predicted adjuvant chemotherapy nonbenefit group (P = 0.0056 for interaction between predicted risk group and adjuvant chemotherapy). Specifically, in the predicted adjuvant chemotherapy benefit group, the patients receiving adjuvant chemotherapy had significant recurrence free survival (RFS) benefit (HR = 0.34; P = 0.016; adjuvant chemotherapy vs. nonadjuvant chemotherapy), while in the predicted adjuvant chemotherapy nonbenefit group, the patients receiving adjuvant chemotherapy actually had worse RFS (HR = 1.86; P = 0.14; adjuvant chemotherapy vs. nonadjuvant chemotherapy) than those who did not receive adjuvant chemotherapy.Conclusions: This study validated that the 12-gene signature and the FFPE-based clinical assay predict that patients whose resected lung adenocarcinomas exhibit an adjuvant chemotherapy benefit gene expression pattern and who then receive adjuvant chemotherapy have significant survival advantage compared with patients whose tumors exhibit the benefit pattern but do not receive adjuvant chemotherapy.

AB - The uncontrolled proliferation of cancer cells has led to the development of small-molecule inhibitors to target cell-cycle progression. Palbociclib, ribociclib, and abemaciclib are ATP-competitive inhibitors of cyclin-dependent kinases 4/6 (CDK4/6), which function early within the G1 phase of the cell cycle. Recently, CDK4/6 inhibitors have gained FDA approval in postmenopausal estrogen receptor (ER)-positive/human epidermal growth factor receptor 2 (HER2)-negative breast cancer and testing in other cancer types is underway. However, resistance to CDK4/6 inhibitors frequently develops. In addition, targeting CDK4/6 may augment the action of immune checkpoint blockade agents. Here, we review recent studies that provide the preclinical rationale for treatment combinations and schedules that include CDK4/6 inhibitors. Furthermore, we discuss inhibitor effects on tumor-infiltrating lymphocytes as a preclinical rationale for targeting CDK4/6 in combination with anti-PD-1 or anti-CTLA-4 antibodies.

AB - Purpose: Glioblastoma (GBM) is the most common primary brain tumor. The identification of blood biomarkers reflecting the tumor status represents a major unmet need for optimal clinical management of patients with GBM. Their high number in body fluids, their stability, and the presence of many tumor-associated proteins and RNAs make extracellular vesicles potentially optimal biomarkers. Here, we investigated the potential role of plasma extracellular vesicles from patients with GBM for diagnosis and follow-up after treatment and as a prognostic tool.Experimental Design: Plasma from healthy controls (n = 33), patients with GBM (n = 43), and patients with different central nervous system malignancies (n = 25) were collected. Extracellular vesicles were isolated by ultracentrifugation and characterized in terms of morphology by transmission electron microscopy, concentration, and size by nanoparticle tracking analysis, and protein composition by mass spectrometry. An orthotopic mouse model of human GBM confirmed human plasma extracellular vesicle quantifications. Associations between plasma extracellular vesicle concentration and clinicopathologic features of patients with GBM were analyzed. All statistical tests were two-sided.Results: GBM releases heterogeneous extracellular vesicles detectable in plasma. Plasma extracellular vesicle concentration was higher in GBM compared with healthy controls (P < 0.001), brain metastases (P < 0.001), and extra-axial brain tumors (P < 0.001). After surgery, a significant drop in plasma extracellular vesicle concentration was measured (P < 0.001). Plasma extracellular vesicle concentration was also increased in GBM-bearing mice (P < 0.001). Proteomic profiling revealed a GBM-distinctive signature.Conclusions: Higher extracellular vesicle plasma levels may assist in GBM clinical diagnosis: their reduction after GBM resection, their rise at recurrence, and their protein cargo might provide indications about tumor, therapy response, and monitoring.

PMID- 30287550 TI - High-salt-recovered sequences are associated with the active chromosomal compartment and with large ribonucleoprotein complexes including nuclear bodies. AB - The mammalian cell nucleus contains numerous discrete suborganelles named nuclear bodies. While recruitment of specific genomic regions into these large ribonucleoprotein (RNP) complexes critically contributes to higher-order functional chromatin organization, such regions remain ill-defined. We have developed the high-salt-recovered sequences-sequencing (HRS-seq) method, a straightforward genome-wide approach whereby we isolated and sequenced genomic regions associated with large high-salt insoluble RNP complexes. By using mouse embryonic stem cells (ESCs), we showed that these regions essentially correspond to the most highly expressed genes, and to cis-regulatory sequences like super enhancers, that belong to the active A chromosomal compartment. They include both cell-type-specific genes, such as pluripotency genes in ESCs, and housekeeping genes associated with nuclear bodies, such as histone and snRNA genes that are central components of Histone Locus Bodies and Cajal bodies. We conclude that HRSs are associated with the active chromosomal compartment and with large RNP complexes including nuclear bodies. Association of such chromosomal regions with nuclear bodies is in agreement with the recently proposed phase separation model for transcription control and might thus play a central role in organizing the active chromosomal compartment in mammals.

AB - Bardet-Biedl syndrome (BBS) is a rare inherited disease caused by defects in the BBSome, an octameric complex of BBS proteins. The BBSome is conserved in most organisms with cilia, which are microtubule (MT)-based cell organelles that protrude from the cell surface and function in motility and sensing. Cilia assembly, maintenance, and function require intraflagellar transport (IFT), a bidirectional motility of multi-megadalton IFT trains propelled by molecular motors along the ciliary MTs. IFT has been shown to transport structural proteins, including tubulin, into growing cilia. The BBSome is an adapter for the transport of ciliary membrane proteins and cycles through cilia via IFT. While both the loss and the abnormal accumulation of ciliary membrane proteins have been observed in bbs mutants, recent data converge on a model where the BBSome mainly functions as a cargo adapter for the removal of certain transmembrane and peripheral membrane proteins from cilia. Here, we review recent data on the ultrastructure of the BBSome and how the BBSome recognizes its cargoes and mediates their removal from cilia. PMID- 30287586 TI - Systems biology primer: the basic methods and approaches. AB - Systems biology is an integrative discipline connecting the molecular components within a single biological scale and also among different scales (e.g. cells, tissues and organ systems) to physiological functions and organismal phenotypes through quantitative reasoning, computational models and high-throughput experimental technologies. Systems biology uses a wide range of quantitative experimental and computational methodologies to decode information flow from genes, proteins and other subcellular components of signaling, regulatory and functional pathways to control cell, tissue, organ and organismal level functions. The computational methods used in systems biology provide systems level insights to understand interactions and dynamics at various scales, within cells, tissues, organs and organisms. In recent years, the systems biology framework has enabled research in quantitative and systems pharmacology and precision medicine for complex diseases. Here, we present a brief overview of current experimental and computational methods used in systems biology. PMID- 30287587 TI - Measuring microtubule dynamics. AB - Microtubules are key players in cellular self-organization, acting as structural scaffolds, cellular highways, force generators and signalling platforms. Microtubules are polar filaments that undergo dynamic instability, i.e. transition between phases of growth and shrinkage. This allows microtubules to explore the inner space of the cell, generate pushing and pulling forces and remodel themselves into arrays with different geometry and function such as the mitotic spindle. To do this, eukaryotic cells employ an arsenal of regulatory proteins to control microtubule dynamics spatially and temporally. Plants and microorganisms have developed secondary metabolites that perturb microtubule dynamics, many of which are in active use as cancer chemotherapeutics and anti inflammatory drugs. Here, we summarize the methods used to visualize microtubules and to measure the parameters of dynamic instability to study both microtubule regulatory proteins and the action of small molecules interfering with microtubule assembly and/or disassembly. PMID- 30287589 TI - The low-down on sleeping down low: pigeons shift to lighter forms of sleep when sleeping near the ground. AB - Sleep in birds is composed of two distinct sub-states, remarkably similar to mammalian slow-wave sleep (SWS) and rapid eye movement (REM) sleep. However, it is unclear whether all aspects of mammalian sleep are present in birds. We examined whether birds suppress REM sleep in response to changes in sleeping conditions that presumably evoke an increase in perceived predation risk, as observed previously in rodents. Although pigeons sometimes sleep on the ground, they prefer to sleep on elevated perches at night, probably to avoid nocturnal mammalian ground predators. Few studies to date have investigated how roosting sites affect sleep architecture. We compared sleep in captive pigeons on days with and without access to high perches. On the first (baseline) day, low and high perches were available; on the second day, the high perches were removed; and on the third (recovery) day, the high perches were returned. The total time spent sleeping did not vary significantly between conditions; however, the time spent in REM sleep declined on the low-perch night and increased above baseline when the pigeons slept on the high perch during the recovery night. Although the amount of SWS did not vary significantly between conditions, SWS intensity was lower on the low-perch night, particularly early in the night. The similarity of these responses between birds and mammals suggests that REM sleep is influenced by at least some ecological factors in a similar manner in both groups of animals. PMID- 30287588 TI - Barriers and Facilitators to Asthma Care After Hospitalization as Reported by Caregivers, Health Providers, and School Nurses. AB - OBJECTIVES: To develop a comprehensive understanding of the barriers and/or facilitators for asthma management for the health professionals and caregivers of children with >1 hospitalization. METHODS: Individual interviews were conducted with family caregivers and health professionals. Focus groups were conducted with school nurses. The interview and focus group guide were used to probe for barriers and facilitators of asthma management. Interviews were recorded, transcribed, and coded by using qualitative software. Themes were identified by using content analysis in the interviews and descriptive qualitative analysis in the focus groups. RESULTS: Caregivers (n = 10), asthma educators (n = 4), physicians (n = 4), and a payer (n = 1) were individually interviewed. School nurses were interviewed via a focus group (n = 10). Children had a median age of 7 years, mean length of stay of 1.9 days, and 56% had a previous hospitalization in the previous 12 months. The "gaps in asthma knowledge" theme (which includes an inadequate understanding of asthma chronicity, activity restrictions, and management with controller medications) emerged as a theme for both caregivers and health professionals but with different health beliefs. School nurses reinforced the difficulty they have in managing children who have asthma in schools, and they identified using the asthma action plan as a facilitator. CONCLUSIONS: Caregivers and health professionals have different health beliefs about asthma knowledge, which raises challenges in the care of a child who has asthma. In addition, school nurses highlight specific barriers that are focused on medication use in schools. A comprehensive understanding of the barriers and facilitators of asthma management that families experience after hospital discharge is crucial to design better efforts to support families. PMID- 30287590 TI - Invertebrate serotonin receptors: a molecular perspective on classification and pharmacology. AB - Invertebrate receptors for the neurotransmitter serotonin (5-HT) have been identified in numerous species from diverse phyla, including Arthropoda, Mollusca, Nematoda and Platyhelminthes. For many receptors, cloning and characterization in heterologous systems have contributed data on molecular structure and function across both closely and distantly related species. This article provides an overview of heterologously expressed receptors, and considers evolutionary relationships among them, classification based on these relationships and nomenclature that reflects classification. In addition, transduction pathways and pharmacological profiles are compared across receptor subtypes and species. Previous work has shown that transduction mechanisms are well conserved within receptor subtypes, but responses to drugs are complex. A few ligands display specificity for different receptors within a single species; however, none acts with high specificity in receptors across different species. Two non-selective vertebrate ligands, the agonist 5-methoxytryptamine and antagonist methiothepin, are active in most receptor subtypes in multiple species and hence bind very generally to invertebrate 5-HT receptors. Future challenges for the field include determining how pharmacological profiles are affected by differences in species and receptor subtype, and how function in heterologous receptors can be used to better understand 5-HT activity in intact organisms. PMID- 30287592 TI - A 17-Year-Old Girl With Weight Loss and Elevated Inflammatory Markers. AB - A 17-year-old girl presented to her primary care physician with a history of unintentional weight loss and vague sensory symptoms, including tingling of her lower extremities. She had a nonrevealing neurology workup and a largely normal rheumatology workup apart from mild elevation in her inflammatory markers. She also had a nonfocal examination apart from a posterior cervical lymph node (2 * 1 cm). Given that she was well appearing, with a nonfocal examination and only mild laboratory abnormalities, she was told to follow-up with rheumatology in 3 months. Around that time, she re-presented to her medical home for a well-child visit, during which she was noted to have continued weight loss, now amounting to 17 lb in 1 year, and marked further elevation in her inflammatory markers. Her laboratory results were also significant for a profound microcytic anemia requiring inpatient admission for blood transfusion. During her admission, she was seen by the rheumatology, gastroenterology, and oncology subspecialty teams. Despite imaging studies and extensive laboratory workup, there was no unifying diagnosis at the time of her hospital discharge. Ultimately, an outpatient imaging study revealed the etiology. PMID- 30287591 TI - Activity Performance Curves of Individuals With Cerebral Palsy. AB - : : media-1vid110.1542/5804911840001PEDS-VA_2017-3723Video Abstract OBJECTIVES: Describe development curves of motor and daily activity performance in individuals with cerebral palsy (CP). METHODS: Participants with CP aged 1 to 20 years at baseline (n = 421) and Gross Motor Functioning Classification System (GMFCS) levels I to V (27% of participants with intellectual disability [ID]) were longitudinally assessed up to a 13-year follow-up period. Motor and daily activity performance were assessed using the relevant subdomains of the Vineland Adaptive Behavior Scales survey. Nonlinear mixed effects analyses were used, estimating the limit (average maximal performance level) and the age by which individuals reached 90% of the limit (age90). RESULTS: Limits of motor performance decreased with each lower functional level. Age90 for motor performance was reached at ~6 to 8 years of age in children with GMFCS levels I to III, and at younger ages in those with lower functional levels. Limits of daily activity performance did not differ between individuals without ID with GMFCS levels I to III. The age90s of daily activities were reached between 11 and 14 (personal), 26 and 32 (domestic), and 22 and 26 years of age (community). Individuals with ID reached lower daily activity performance limits earlier. CONCLUSIONS: Individuals with CP continue to develop motor performance after gross motor capacity limits are reached. For those without ID, daily activities continue to develop into their 20s. Individuals who are severely affected functionally have the least favorable development of motor performance, and those with ID have the least favorable development of daily activity performance. PMID- 30287594 TI - PEHO syndrome: the endpoint of different genetic epilepsies. AB - BACKGROUND: Progressive encephalopathy, hypsarrhythmia and optic atrophy (PEHO) has been described as a clinically distinct syndrome. It has been postulated that it is an autosomal recessive condition. However, the aetiology is poorly understood, and the genetic basis of the condition has not been fully elucidated. Our objective was to discover if PEHO syndrome is a single gene disorder. METHOD: Children with PEHO and PEHO-like syndrome were recruited. Clinical, neurological and dysmorphic features were recorded; EEG reports and MRI scans were reviewed. Where possible, exome sequencing was carried out first to seek mutations in known early infantile developmental and epileptic encephalopathy (DEE) genes and then to use an agnostic approach to seek novel candidate genes. We sought intra interfamilial phenotypic correlations and genotype-phenotype correlations when pathological mutations were identified. RESULTS: Twenty-three children were recruited from a diverse ethnic background, 19 of which were suitable for inclusion. They were similar in many of the core and the supporting features of PEHO, but there was significant variation in MRI and ophthalmological findings, even between siblings with the same mutation. A pathogenic genetic variant was identified in 15 of the 19 children. One further girl's DNA failed analysis, but her two affected sisters shared confirmed variants. Pathogenic variants were identified in seven different genes. CONCLUSIONS: We found significant clinical and genetic heterogeneity. Given the intrafamily variation demonstrated, we question whether the diagnostic criteria for MRI and ophthalmic findings should be altered. We also question whether PEHO and PEHO-like syndrome represent differing points on a clinical spectrum of the DEE. We conclude that PEHO and PEHO-like syndrome are clinically and genetically diverse entities-and are phenotypic endpoints of many severe genetic encephalopathies. PMID- 30287593 TI - 16p13.11 microduplication in 45 new patients: refined clinical significance and genotype-phenotype correlations. AB - BACKGROUND: The clinical significance of 16p13.11 duplications remains controversial while frequently detected in patients with developmental delay (DD), intellectual deficiency (ID) or autism spectrum disorder (ASD). Previously reported patients were not or poorly characterised. The absence of consensual recommendations leads to interpretation discrepancy and makes genetic counselling challenging. This study aims to decipher the genotype-phenotype correlations to improve genetic counselling and patients' medical care. METHODS: We retrospectively analysed data from 16 013 patients referred to 12 genetic centers for DD, ID or ASD, and who had a chromosomal microarray analysis. The referring geneticists of patients for whom a 16p13.11 duplication was detected were asked to complete a questionnaire for detailed clinical and genetic data for the patients and their parents. RESULTS: Clinical features are mainly speech delay and learning disabilities followed by ASD. A significant risk of cardiovascular disease was noted. About 90% of the patients inherited the duplication from a parent. At least one out of four parents carrying the duplication displayed a similar phenotype to the propositus. Genotype-phenotype correlations show no impact of the size of the duplicated segment on the severity of the phenotype. However, NDE1 and miR-484 seem to have an essential role in the neurocognitive phenotype. CONCLUSION: Our study shows that 16p13.11 microduplications are likely pathogenic when detected in the context of DD/ID/ASD and supports an essential role of NDE1 and miR-484 in the neurocognitive phenotype. Moreover, it suggests the need for cardiac evaluation and follow-up and a large study to evaluate the aortic disease risk. PMID- 30287595 TI - Mosaicism and incomplete penetrance of PCDH19 mutations. AB - BACKGROUND: Mutations in the PCDH19 gene have mainly been reported in female patients with epilepsy. To date, PCDH19 mutations have been reported in hundreds of females and only in 10 mosaic male epileptic patients with mosaicism. OBJECTIVE: We aimed to investigate the occurrence of mosaic PCDH19 mutations in 42 families comprising at least one patient with PCDH19-related epilepsy. METHODS: Two male patients with mosaic PCDH19 variants were identified using targeted next-generation sequencing. Forty female patients with PCDH19 variants were identified by Sanger sequencing and Multiple Ligation Probe Amplification (MLPA). Microdroplet digital PCR was used to quantify the mutant allelic fractions (MAFs) in 20 families with PCDH19 variants. RESULTS: Five mosaic individuals, four males and one female, were identified in total. Mosaic variant was confirmed in multiple somatic tissues from one male patient and in blood from the other male patient. Among 22 female patients harbouring a newly occurred PCDH19 variant identified by Sanger sequencing and MLPA, Sanger sequencing revealed two mosaic fathers (9%, 2/22), one with two affected daughters and the other with an affected child. Two asymptomatic mosaic fathers were confirmed as gonosomal mosaicism, with MAFs ranging from 4.16% to 37.38% and from 1.27% to 19.13%, respectively. In 11 families with apparent de novo variants, 1 female patient was identified as a mosaic with a blood MAF of 26.72%. CONCLUSION: Our study provides new insights into phenotype-genotype correlations in PCDH19 related epilepsy and the finding of high-frequency mosaicism has important implications for genetic counselling. PMID- 30287596 TI - Haemophagocytic lymphohistiocytosis complicating pembrolizumab treatment for metastatic breast cancer in a patient with the PRF1A91V gene polymorphism. AB - BACKGROUND: Immune checkpoint inhibitor therapy is a modern breakthrough in medical oncology, but it can precipitate inflammatory and autoimmune adverse effects. Among the most serious of these toxicities is haemophagocytic lymphohistiocytosis (HLH), a life-threatening disorder of unbridled immune activation that results in injury to multiple organ systems. OBJECTIVE: Description of a case of pembrolizumab-associated HLH in a patient with a proposed underlying genetic risk factor for its occurrence. METHODS AND RESULTS: We describe a patient with aggressive metastatic breast cancer who developed HLH while undergoing experimental treatment with pembrolizumab, resulting in critical illness and multiorgan system failure. Pembrolizumab discontinuation and high dose corticosteroids were effective in managing HLH. Subsequent next-generation sequencing of 15 genes associated with HLH revealed a germline polymorphism in perforin-1 (PRF1), PRFA91V, that may have predisposed the patient to develop HLH. The patient has had no evidence of malignancy for 2 years following recovery despite receiving no further cancer-directed treatment. CONCLUSIONS: HLH is a rare but serious complication of immune checkpoint blockade. Patients with underlying hypomorphic alleles in PRF1 may be predisposed to develop this toxicity. Further studies are necessary to confirm a possible link between perforin gene mutations and immune checkpoint blockade-associated HLH.

PMID- 30287599 TI - Investigation of clinically relevant germline variants detected by next generation sequencing in patients with childhood cancer: a review of the literature. AB - Genetic predisposition is an important underlying cause of childhood cancer, although the proportion of patients with childhood cancer carrying predisposing pathogenic germline variants is uncertain. This review considers the pathogenic or likely pathogenic germline variants reported by six studies that used next generation sequencing to investigate genetic predisposition in selected cohorts of patients with childhood cancer and used incompletely overlapping gene sets for analysis and interpretation. These six studies reported that 8.5%-35.5% of patients with childhood cancer carried clinically relevant germline variants. Analysis of 52 autosomal dominant cancer predisposition genes assumed common to all six studies showed that 5.5%-25.8% of patients with childhood cancer carried pathogenic or likely pathogenic germline variants in at least one of these genes. When only non-central nervous system solid tumours (excluding adrenocortical carcinomas) were considered, 8.5%-10.3% of the patients carried pathogenic or likely pathogenic germline variants in at least one of 52 autosomal dominant cancer predisposition genes. There was a lack of concordance between the genotype and phenotype in 33.3%-57.1% of the patients reported with pathogenic or likely pathogenic germline variants, most of which represented variants in autosomal dominant cancer predisposition genes associated with adult onset cancers. In summary, germline genetic testing in patients with childhood cancer requires clear definition of phenotypes and genes considered for interpretation, with potential to inform and broaden childhood cancer predisposition syndromes. PMID- 30287597 TI - Progression from islet autoimmunity to clinical type 1 diabetes is influenced by genetic factors: results from the prospective TEDDY study. AB - BACKGROUND: Progression time from islet autoimmunity to clinical type 1 diabetes is highly variable and the extent that genetic factors contribute is unknown. METHODS: In 341 islet autoantibody-positive children with the human leucocyte antigen (HLA) DR3/DR4-DQ8 or the HLA DR4-DQ8/DR4-DQ8 genotype from the prospective TEDDY (The Environmental Determinants of Diabetes in the Young) study, we investigated whether a genetic risk score that had previously been shown to predict islet autoimmunity is also associated with disease progression. RESULTS: Islet autoantibody-positive children with a genetic risk score in the lowest quartile had a slower progression from single to multiple autoantibodies (p=0.018), from single autoantibodies to diabetes (p=0.004), and by trend from multiple islet autoantibodies to diabetes (p=0.06). In a Cox proportional hazards analysis, faster progression was associated with an increased genetic risk score independently of HLA genotype (HR for progression from multiple autoantibodies to type 1 diabetes, 1.27, 95% CI 1.02 to 1.58 per unit increase), an earlier age of islet autoantibody development (HR, 0.68, 95% CI 0.58 to 0.81 per year increase in age) and female sex (HR, 1.94, 95% CI 1.28 to 2.93). CONCLUSIONS: Genetic risk scores may be used to identify islet autoantibody-positive children with high risk HLA genotypes who have a slow rate of progression to subsequent stages of autoimmunity and type 1 diabetes. PMID- 30287600 TI - Preventive effect of oral magnesium in postmastectomy pain: protocol for a randomised, double-blind, controlled clinical trial. AB - INTRODUCTION: Breast cancer affects 1 in 10 women worldwide, and mastectomy is a cause of chronic pain with neuropathic characteristics. N-methyl-D-aspartate receptor (NMDAR) antagonists such as ketamine, memantine, dextromethorphan or magnesium are used to treat refractory pain by blocking NMDAR. Oral memantine has been shown to prevent postmastectomy pain and cognitive impact and to maintain quality of life. Likewise, the present study is intended to assess the preventive effect of oral magnesium, administered ahead of mastectomy, on the development of neuropathic pain. As a physiological blocker of NMDAR, magnesium could be an interesting candidate to prevent postoperative pain and associated comorbidities, including cognitive and emotional disorders, multiple analgesic consumption and impaired quality of life. METHODS AND ANALYSIS: A randomised double-blind controlled clinical trial (NCT03063931) will include 100 women with breast cancer undergoing mastectomy at the Oncology Hospital, Clermont-Ferrand, France. Magnesium (100 mg/day; n=50) or placebo (n=50) will be administered for 6 weeks, starting 2 weeks before surgery. Intensity of pain, cognitive and emotional function and quality of life will be assessed by questionnaires. The primary endpoint is pain intensity on a 0-10 numerical rating scale at 1 month postmastectomy. Data analysis will use mixed models; all tests will be two tailed, with type-I error set at alpha=0.05. ETHICS AND DISSEMINATION: The study protocol and informed consent form were approved in December 2016 by the French Research Ethics Committee (South East VI Committee). Results will be communicated in various congresses and published in international publications. TRIAL REGISTRATION NUMBER: NCT03063931. PMID- 30287602 TI - Protocol for a prospective multicentre registry cohort study on suicide attempters given the assertive case management intervention after admission to an emergency department in Japan: post-ACTION-J Study (PACS). AB - INTRODUCTION: Suicide attempt is the most important risk factor for later suicide. A randomised-controlled, multicentre trial of postsuicide attempt case management for the prevention of further suicide attempts in Japan, named ACTION J, has established effective interventions for prevention of suicide reattempts. The ACTION-J assertive case management intervention programme was adopted by the Japanese Ministry of Health, Labour and Welfare in 2016, when medical fees were revised. This nationwide programme is provided to patients who attempt suicide and who are admitted to emergency departments in Japan.The aim of the present study is to examine the current implementation status of the ACTION-J programme. The present study also aims to clarify which patients' and hospitals' factors affect the implementation of the programme. METHODS AND ANALYSIS: This is a prospective, multicentre, patient registry cohort study. Participants will be suicide attempters admitted to the emergency departments of medical facilities with both psychiatry and emergency departments. The assertive case management programme will be delivered to participants by a case manager for up to 24 weeks, based on psychiatric diagnoses, social risks and patient needs. The core feature of the programme is to encourage patients to participate in psychiatric treatment.The primary outcome will be the proportion of patients still participating in the case management intervention at 24 weeks after registration. The secondary outcomes will include measures of the fidelity of the case management intervention. The fidelity will be evaluated using a fidelity assessment manual developed by the study group. ETHICS AND DISSEMINATION: This observational study has been approved by the ethics board of Sapporo Medical University. Enrolment began in October 2016 and will continue until December 2018. Dissemination plans include presentations at scientific conferences and scientific publications. TRIAL REGISTRATION: UMIN000024474. PMID- 30287601 TI - Enhancing Social Interaction in Depression (SIDE study): protocol of a randomised controlled trial on the effects of a Cognitively Based Compassion Training (CBCT) for couples. AB - INTRODUCTION: Positive social interactions (PSIs) and stable relationships can exert substantial benefits on health. However, patients suffering from depression benefit less from these health-promoting effects. Moreover, relationship quality and even partners' health has been found to be negatively affected by depressive symptomatology, which may result in overall impairments in social functioning of a romantic couple. Psychobiological research indicates that these impairments may be accompanied by a maladaptive regulation of the patient's neuroendocrine response to external stressors. Concerning the improvement of social functioning, first studies showed promising results of "Cognitively Based Compassion Training (CBCT(r))". However, randomised trials are still scarce. Previous programmes did not involve participation of the patient's romantic partner. Therefore, the present study aims to investigate whether a CBCT(r) programme adapted for couples (CBCT(r)-fC) can improve depressive symptoms, distress, social interaction skills and the neurobiological regulation of stress. METHODS AND ANALYSIS: Couples with the female partner suffering from depression will be invited to participate in a pre-to-post intervention assessment on two consecutive days, respectively, involving a standardised PSI task, eye-tracking, ECG recordings, saliva-sampling, blood-sampling and questionnaire data. After baseline assessment, participating couples will be randomised to either a 10 week CBCT(r)-fC or to a treatment as usual control condition. The primary endpoint is the reduction of depressive symptoms measured by the Hamilton Depression Rating Scale. Secondary outcomes encompass self-rated depression (Beck Depression Inventory), attention towards the partners face during PSI (eye tracking), stress-related biomarkers (cortisol, alpha-amylase, interleukin (IL)-1beta/IL-6, heart rate variability), methylation of oxytocin-receptor-genes and serotonin-transporter-genes and self-ratings of psychological constructs such as relationship quality and empathy. ETHICS AND DISSEMINATION: Ethical approval has been obtained by the Ethics Committee of the Medical Faculty Heidelberg. Results will be presented in international, peer reviewed journals and on conferences in the field of clinical psychology and psychiatry. TRIAL REGISTRATION NUMBER: NCT03080025. PMID- 30287603 TI - Legacy effects of statins on cardiovascular and all-cause mortality: a meta analysis. AB - OBJECTIVES: To assess evidence for 'legacy' (post-trial) effects on cardiovascular disease (CVD) mortality and all-cause mortality among adult participants of placebo-controlled randomised controlled trials (RCTs) of statins. DESIGN: Meta-analysis of aggregate data. SETTING/PARTICIPANTS: Placebo controlled statin RCTS for primary and secondary CVD prevention. METHODS: Data sources: PubMed, Embase from inception and forward citations of Cholesterol Treatment Trialists' Collaborators RCTs to 16 June 2016. STUDY SELECTION: Two independent reviewers identified all statin RCT follow-up reports including >=1000 participants, and cardiovascular and all-cause mortality. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers extracted data in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. MAIN OUTCOMES: Post-trial CVD and all-cause mortality. RESULTS: We included eight trials, with mean post-trial follow-up ranging from 1.6 to 15.1 years, and including 13 781 post-trial deaths (6685 CVD). Direct effects of statins within trials were greater than legacy effects post-trials. The pooled data from all eight studies showed no evidence overall of legacy effects on CVD mortality, but some evidence of legacy effects on all-cause mortality (p=0.01). Exploratory subgroup analysis found possible differences in legacy effect for primary prevention trials compared with secondary prevention trials for both CVD mortality (p=0.15) and all-cause mortality (p=0.02). Pooled post-trial HR for the three primary prevention studies demonstrated possible post-trial legacy effects on CVD mortality (HR=0.87; 95% CI 0.79 to 0.95) and on all-cause mortality (HR=0.90; 95% CI 0.85 to 0.96). CONCLUSIONS: Possible post-trial statin legacy effects on all-cause mortality appear to be driven by the primary prevention studies. Although these relative benefits were smaller than those observed within the trial, the absolute benefits may be similar for the two time periods. Analysis of individual patient data from follow-up studies after placebo controlled statin RCTs in lower-risk populations may provide more definitive evidence on whether early treatment of subclinical atherosclerosis is likely to be beneficial. PMID- 30287605 TI - Ultrasound assessment of diaphragmatic dysfunction as a predictor of weaning outcome from mechanical ventilation: a systematic review and meta-analysis. AB - OBJECTIVE: The aim of this systematic review was to assess the diaphragmatic dysfunction (DD) as a predictor of weaning outcome. BACKGROUND: Successful weaning depends on several factors: muscle strength, cardiac, respiratory and metabolic. Acquired weakness in mechanical ventilation is a growing important cause of weaning failure. With the development of ultrasonography, DD can be evaluated with ultrasound in weakness patients to predict weaning outcomes. METHODS: The Cochrane Library, PubMed, Embase, Ovid Medline, WanFang Data and CNKI were systematically searched from the inception to September 2017. Ultrasound assessment of DD in adult mechanical ventilation patients was included. Two independent investigators assessed study quality in accordance with the Quality Assessment of Diagnostic Accuracy Studies-2 tool. The primary outcome was diaphragmatic thickness and excursion in the weaning success and failure group. The secondary outcome was the influence of DD on weaning outcome. RESULTS: Eleven studies involving a total of 436 patients were included. There were eight studies comparing diaphragmatic excursion (DE), five comparing the diaphragmatic thickening fraction (DTF) and two comparing DD between groups with and without successful weaning. Overall, the DE or DTF had a pooled sensitivity of 0.85 (95% CI 0.77 to 0.91) and a pooled specificity of 0.74 (95% CI 0.66 to 0.80) for predicting weaning success. There was high heterogeneity among the included studies (I2=80%; p=0.0006). The rate of weaning failure was significantly increased in patients with DD (OR 8.82; 95% CI 3.51 to 22.13; p<0.00001). CONCLUSIONS: Both DE and DTF showed good diagnostic performance to predict weaning outcomes in spite of limitations included high heterogeneity among the studies. DD was found to be a predictor of weaning failure in critically ill patients. PMID- 30287606 TI - Development of a risk predictive scoring system to identify patients at risk of representation to emergency department: a retrospective population-based analysis in Australia. AB - OBJECTIVE: To examine the characteristics of frequent visitors (FVs) to emergency departments (EDs) and develop a predictive model to identify those with high risk of a future representations to ED among younger and general population (aged <=70 years). DESIGN AND SETTING: A retrospective analysis of ED data targeting younger and general patients (aged <=70 years) were collected between 1 January 2009 and 30 June 2016 from a public hospital in Australia. PARTICIPANTS: A total of 343 014 ED presentations were identified from 170 134 individual patients. MAIN OUTCOME MEASURES: Proportion of FVs (those attending four or more times annually), demographic characteristics (age, sex, indigenous and marital status), mode of separation (eg, admitted to ward), triage categories, time of arrival to ED, referral on departure and clinical conditions. Statistical estimates using a mixed-effects model to develop a risk predictive scoring system. RESULTS: The FVs were characterised by young adulthood (32.53%) to late-middle (26.07%) aged patients with a higher proportion of indigenous (5.7%) and mental health-related presentations (10.92%). They were also more likely to arrive by ambulance (36.95%) and leave at own risk without completing their treatments (9.8%). They were also highly associated with socially disadvantage groups such as people who have been divorced, widowed or separated (12.81%). These findings were then used for the development of a predictive model to identify potential FVs. The performance of our derived risk predictive model was favourable with an area under the receiver operating characteristic (ie, C-statistic) of 65.7%. CONCLUSION: The development of a demographic and clinical profile of FVs coupled with the use of predictive model can highlight the gaps in interventions and identify new opportunities for better health outcome and planning. PMID- 30287604 TI - Association of neighbourhood socioeconomic status and diabetes burden using electronic health records in Madrid (Spain): the HeartHealthyHoods study. AB - OBJECTIVE: To study the association between neighbourhood socioeconomic status and diabetes prevalence, incidence, and control in the entire population of northeastern Madrid, Spain. SETTING: Electronic health records of the primary care system in four districts of Madrid (Spain). PARTICIPANTS: 269 942 people aged 40 or older, followed from 2013 to 2014. EXPOSURE: Neighbourhoodsocioeconomic status (NSES), measured using a composite index of seven indicators from four domains of education, wealth, occupation and living conditions. PRIMARY OUTCOME MEASURES: Diagnosis of diabetes based on ICPC-2 codes and glycated haemoglobin (HbA1c %). RESULTS: In regression analyses adjusted by age and sex and compared with individuals living in low NSES neighbourhoods, men living in medium and high NSES neighbourhoods had 10% (95% CI: 6% to 15%) and 29% (95% CI: 25% to 32%) lower prevalence of diabetes, while women had 27% (95% CI: 23% to 30%) and 50% (95% CI: 47% to 52%) lower prevalence of diabetes. Moreover, the hazard of diabetes in men living in medium and high NSES neighbourhoods was 13% (95% CI: 1% to 23%) and 20% (95% CI: 9% to 29%) lower, while the hazard of diabetes in women living in medium and high NSES neighbourhoods was 17% (95% CI: 3% to 29%) and 31% (95% CI: 20% to 41%) lower. Individuals living in medium and high SES neighbourhoods had 8% (95% CI: 2% to 15%) and 15% (95% CI: 9% to 21%) lower prevalence of lack of diabetes control, and a decrease in average HbA1c % of 0.05 (95% CI: 0.01 to 0.10) and 0.11 (95% CI: 0.06 to 0.15). CONCLUSIONS: Diabetes prevalence, incidence and lack of control increased with decreasing NSES in a southern European city. Future studies should provide mechanistic insights and targets for intervention to address this health inequity. PMID- 30287607 TI - Prevention of postcontrast acute kidney injury after percutaneous transluminal angioplasty by inducing RenalGuard controlled furosemide forced diuresis with matched hydration: study protocol for a randomised controlled trial. AB - INTRODUCTION: Percutaneous transluminal angioplasty (PTA) is often complicated due to postcontrast acute kidney injury (PC-AKI) in patients diagnosed with chronic kidney disease (CKD). Hydration therapy is the cornerstone in the prevention of PC-AKI. Furosemide forced diuresis with matched hydration using the RenalGuard system enables a steady balance between diuresis and hydration. A randomised controlled trial will be performed in order to investigate whether furosemide forced diuresis with matched hydration in combination with the RenalGuard system decreases incidence of PC-AKI in patients with CKD receiving a PTA of the lower extremities. Furthermore, we will investigate whether sampling of urine biomarkers 4 hours after intervention can detect PC-AKI in an earlier stage compared with the golden standard, serum creatinine 48-72 hours postintervention. METHODS AND ANALYSIS: A single-centre randomised controlled trial will be conducted. Patients >18 years in need of a PTA of the lower extremities and diagnosed with CKD will be randomly assigned to receive either standard of care prehydration and posthydration or furosemide forced diuresis with matched hydration periprocedural using the RenalGuard system. Four hours postintervention, a urine sample will be collected of all participating patients. Serum creatinine will be sampled within 10 days prior to intervention as well as 1, 3 and 30 days postintervention. The primary endpoint is incidence of PC-AKI post-PTA. Secondary endpoint is the rise of urine biomarkers 4 hours postintervention. ETHICS AND DISSEMINATION: Study protocol is approved by the research ethics committee and institutional review board (reference number 16 T 201 and NL59809.096.16). Study results will be disseminated by oral presentation at conferences and will be submitted to a peer-reviewed journal. It is anticipated that study results will offer a solution to contrast-induced nephropathy in patients with CKD receiving a PTA of the lower extremities.

PMID- 30287608 TI - Impact of PCSK9 monoclonal antibodies on circulating hs-CRP levels: a systematic review and meta-analysis of randomised controlled trials. AB - OBJECTIVE: To evaluate the potential effects of proprotein convertase subtilisin/kexin type 9 monoclonal antibody (PCSK9-mAb) on high-sensitivity C reactive protein (hs-CRP) concentrations. DESIGN: A systematic review and meta analysis of randomised controlled trials. DATA SOURCES: PubMed, MEDLINE, the Cochrane Library databases, ClinicalTrials.gov and recent conferences were searched from inception to May 2018. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: All randomised controlled trials that reported changes of hs-CRP were included. RESULTS: Ten studies involving 4198 participants were identified. PCSK9-mAbs showed a slight efficacy in reducing hs-CRP (-0.04 mg/L, 95% CI: -0.17 to 0.01) which was not statistically different. The results did not altered when subgroup analyses were performed including PCSK9-mAb types (alirocumab: 0.12 mg/L, 95% CI: -0.18 to 0.43; evolocumab: 0.00 mg/L, 95% CI: -0.07 to 0.07; LY3015014: -0.48 mg/L, 95% CI: -1.28 to 0.32; RG7652: 0.35 mg/L, 95% CI: -0.26 to 0.96), treatment duration (<=12w: 0.00 mg/L, 95% CI: -0.07 to 0.07; >12w: -0.11 mg/L, 95% CI: 0.45 to -0.23), participant characteristics (familial hypercholesterolaemia: 0.00 mg/L, 95% CI: -0.07 to 0.07; non-familial hypercholesterolaemia: 0.07 mg/L, 95% CI: -0.12 to 0.26; mix: -0.48 mg/L, 95% CI: -1.28 to 0.32) and treatment methods (monotherapy: 0.00 mg/L, -0.08 to 0.07; combination therapy: -0.08 mg/L, -0.37 to 0.21). Meta-regression analyses suggested no significant linear correlation between baseline age (p=0.673), sex (p=0.645) and low-density lipoprotein cholesterol reduction (p=0.339). CONCLUSIONS: Our updated meta-analysis suggested that PCSK9-mAbs had no significant impact on circulating hs-CRP levels irrespective of PCSK9-mAb types, participant characteristics and treatment duration or methods. PMID- 30287609 TI - Work-related mobility and experiences of gender-based violence among female sex workers in Iringa, Tanzania: a cross-sectional analysis of baseline data from Project Shikamana. AB - OBJECTIVES: To examine how work-related mobility among female sex workers (FSWs) is associated with gender-based violence (GBV) in Iringa, Tanzania. DESIGN: Cross sectional analyses were conducted on baseline data gathered between October 2015 and April 2016 from FSWs participating in Project Shikamana, a community empowerment-based combination HIV prevention intervention. SETTING: Participants were recruited for the baseline study using venue-based time-location sampling in two communities in Iringa, Tanzania. PARTICIPANTS: FSWs were eligible for participation if they were 18 years or older and had exchanged sex for money within the past month. Four-hundred ninety-six FSWs participated in the baseline survey. PRIMARY AND SECONDARY OUTCOME MEASURES: Any recent experience of GBV was examined by recent work-related mobility among FSWs. Any recent experience of GBV was also disaggregated by severity for analyses. All bivariate and multivariate binary and multinomial logistic regressions adjusted for intraclass correlations among women recruited from the same venues. RESULTS: Forty per cent of participants experienced recent physical or sexual violence, and 30% recently experienced severe physical or sexual violence. Thirty-three per cent of participants recently exchanged sex for money outside of their district or region, and 12% were both intraregionally and inter-regionally mobile for sex work. Intraregionally and inter-regionally mobile FSWs had 1.9 times greater odds of reporting recent GBV (adjusted OR: 1.89; 95% CI: 1.06 to 3.38; p=0.031) compared with non-mobile FSWs and a 2.5 times higher relative risk for recent experience of severe GBV relative to no recent GBV (relative risk ratio: 2.51; 95% CI: 1.33 to 4.74; p=0.005). CONCLUSIONS: Mobility for sex work may increase FSWs' exposure to GBV, particularly more severe GBV. The vulnerability of mobile FSWs to violence, particularly severe forms, demands inclusive services that are accessible to mobile FSWs. PMID- 30287610 TI - OPtimising Treatment for MIld Systolic hypertension in the Elderly (OPTiMISE): protocol for a randomised controlled non-inferiority trial. AB - INTRODUCTION: Recent evidence suggests that larger blood pressure reductions and multiple antihypertensive drugs may be harmful in older people, particularly frail individuals with polypharmacy and multimorbidity. However, there is a lack of evidence to support deprescribing of antihypertensives, which limits the practice of medication reduction in routine clinical care. The aim of this trial is to examine whether antihypertensive medication reduction is possible in older patients without significant changes in blood pressure control at follow-up. METHODS AND ANALYSIS: This trial will use a primary care-based, open-label, randomised controlled trial design. A total of 540 participants will be recruited, aged >=80 years, with systolic blood pressure <150 mm Hg and receiving >=2 antihypertensive medications. Participants will have no compelling indication for medication continuation and will be considered to potentially benefit from medication reduction due to existing polypharmacy, comorbidity and frailty. Following a baseline appointment, individuals will be randomised to a strategy of medication reduction (intervention) with optional self-monitoring or usual care (control). Those in the intervention group will have one antihypertensive medication stopped. The primary outcome will be to determine if a reduction in medication can achieve a proportion of participants with clinically safe blood pressure levels at 12-week follow-up (defined as a systolic blood pressure <150 mm Hg), which is non-inferior (within 10%) to that achieved by the usual care group. Qualitative interviews will be used to understand the barriers and facilitators to medication reduction. The study will use economic modelling to predict the long-term effects of any observed changes in blood pressure and quality of life. ETHICS AND DISSEMINATION: The protocol, informed consent form, participant information sheet and all other participant facing material have been approved by the Research Ethics Committee (South Central-Oxford A; ref 16/SC/0628), Medicines and Healthcare products Regulatory Agency (ref 21584/0371/001-0001), host institution(s) and Health Research Authority. All research outputs will be published in peer-reviewed journals and presented at national and international conferences.

PMID- 30287611 TI - Health information technology uses for primary prevention in preventive medicine: a scoping review protocol. AB - INTRODUCTION: The use of health information technologies (HITs) has been associated with positive benefits such as improved health outcomes and improved health services. Results from empirical studies reported potential benefits of HITs in preventive medicine measures such as primary prevention. This review will examine the broad range of HITs and their uses and effectiveness in primary prevention. METHODS AND ANALYSIS: We will conduct searches in relevant databases (MEDLINE, EMBASE, the Cochrane Methodology Register, Cochrane Database of Systematic Reviews, CINAHL, SCOPUS and Web of Science) using Arksey and O'Malley's scoping review methodology. The scoping review will include all study designs to identify the literature on HIT uses. Two reviewers will independently screen the literature following our screening criteria and using a data abstraction form. Findings will be summarised quantitatively (using numerical counts of HITs) and qualitatively (using narrative synthesis). ETHICS AND DISSEMINATION: The study will synthesise data from published literature and will not require an ethical approval. The results of the review will be disseminated through a peer-reviewed journal. PMID- 30287612 TI - Improving sensitivity to eye gaze cues in autism using serious game technology: study protocol for a phase I randomised controlled trial. AB - INTRODUCTION: Autism spectrum disorder (ASD) is characterised by impairments in social communication. Core symptoms are deficits in social looking behaviours, including limited visual attention to faces and sensitivity to eye gaze cues. We designed an intervention game using serious game mechanics for adolescents with ASD. It is designed to train individuals with ASD to discover that the eyes, and shifts in gaze specifically, provide information about the external world. We predict that the game will increase understanding of gaze cues and attention to faces. METHODS AND ANALYSIS: The Social Games for Adolescents with Autism (SAGA) trial is a preliminary, randomised controlled trial comparing the intervention game with a waitlist control condition. 34 adolescents (10-18 years) with ASD with a Full-Scale IQ between 70 and 130 and a minimum second grade reading level, and their parents, will be randomly assigned (equally to intervention or the control condition) following baseline assessments. Intervention participants will be instructed to play the computer game at home on a computer for ~30 min, three times a week. All families are tested in the lab at baseline and approximately 2 months following randomisation in all measures. Primary outcomes are assessed with eye tracking to measure sensitivity to eye gaze cues and social visual attention to faces; secondary outcomes are assessed with questionnaires to measure social skills and autism-like behaviours. The analyses will focus on evaluating the feasibility, safety and preliminary effectiveness of the intervention. ETHICS AND DISSEMINATION: SAGA is approved by the Institutional Review Board at Pennsylvania State University (00005097). Findings will be disseminated via scientific conferences and peer-reviewed journals and to participants via newsletter. The intervention game will be available to families in the control condition after the full data are collected and if analyses indicate that it is effective. TRIAL REGISTRATION NUMBER: NCT02968225. PMID- 30287613 TI - Plasma concentrations of second-line antituberculosis drugs in relation to minimum inhibitory concentrations in multidrug-resistant tuberculosis patients in China: a study protocol of a prospective observational cohort study. AB - INTRODUCTION: Individualised treatment through therapeutic drug monitoring (TDM) may improve tuberculosis (TB) treatment outcomes but is not routinely implemented. Prospective clinical studies of drug exposure and minimum inhibitory concentrations (MICs) in multidrug-resistant TB (MDR-TB) are scarce. This translational study aims to characterise the area under the concentration-time curve of individual MDR-TB drugs, divided by the MIC for Mycobacterium tuberculosis isolates, to explore associations with markers of treatment progress and to develop useful strategies for clinical implementation of TDM in MDR-TB. METHODS AND ANALYSIS: Adult patients with pulmonary MDR-TB treated in Xiamen, China, are included. Plasma samples for measure of drug exposure are obtained at 0, 1, 2, 4, 6, 8 and 10 hours after drug intake at week 2 and at 0, 4 and 6 hours during weeks 4 and 8. Sputum samples for evaluating time to culture positivity and MIC determination are collected at days 0, 2 and 7 and at weeks 2, 4, 8 and 12 after treatment initiation. Disease severity are assessed with a clinical scoring tool (TBscore II) and quality of life evaluated using EQ-5D-5L. Drug concentrations of pyrazinamide, ethambutol, levofloxacin, moxifloxacin, cycloserine, prothionamide and para-aminosalicylate are measured by liquid chromatography tandem-mass spectrometry and the levels of amikacin measured by immunoassay. Dried blood spot on filter paper, to facilitate blood sampling for analysis of drug concentrations, is also evaluated. The MICs of the drugs listed above are determined using custom-made broth microdilution plates and MYCOTB plates with Middlebrook 7H9 media. MIC determination of pyrazinamide is performed in BACTEC MGIT 960. ETHICS AND DISSEMINATION: This study has been approved by the ethical review boards of Karolinska Institutet, Sweden and Fudan University, China. Informed written consent is given by participants. The study results will be submitted to a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT02816931; Pre-results. PMID- 30287615 TI - Real-world evidence for postgraduate students and professionals in healthcare: protocol for the design of a blended massive open online course. AB - INTRODUCTION: There is an increased need for improving data science skills of healthcare professionals. Massive open online courses (MOOCs) provide the opportunity to train professionals in a sustainable and cost-effective way. We present a protocol for the design and development of a blended MOOC on real-world evidence (RWE) aimed at improving RWE data science skills. The primary objective is to provide the opportunity to understand the fundamentals of RWE data science and to implement methods for analysing RWD. The blended format of MOOC will combine the expertise of healthcare professionals joining the course online with the on-campus students. We expect learners to take skills taught in MOOC and use them to seek new employment or to explore entpreneurship activities in these domains.

AB - OBJECTIVES: To describe trends in caesarean sections and facilities performing caesareans over time in Tanzania and examine the readiness of such facilities in terms of infrastructure, equipment and staffing. DESIGN: Nationally representative, repeated cross-sectional surveys of women and health facilities. SETTING: Tanzania. PARTICIPANTS: Women of reproductive age and health facility staff. MAIN OUTCOME MEASURES: Population-based caesarean rate, absolute annual number of caesareans, percentage of facilities reporting to perform caesareans and three readiness indicators for safe caesarean care: availability of consistent electricity, 24 hour schedule for caesarean and anaesthesia providers, and availability of all general anaesthesia equipment. RESULTS: The caesarean rate in Tanzania increased threefold from 2% in 1996 to 6% in 2015-16, while the total number of births increased by 60%. As a result, the absolute number of caesareans increased almost fivefold to 120 000 caesareans per year. The main mechanism sustaining the increase in caesareans was the doubling of median caesarean volume among public hospitals, from 17 caesareans per month in 2006 to 35 in 2014-15. The number of facilities performing caesareans increased only modestly over the same period. Less than half (43%) of caesareans in Tanzania in 2014-15 were performed in facilities meeting the three readiness indicators. Consistent electricity was widely available, and 24 hour schedules for caesarean and (less systematically) anaesthesia providers were observed in most facilities; however, the availability of all general anaesthesia equipment was the least commonly reported indicator, present in only 44% of all facilities (34% of public hospitals). CONCLUSIONS: Given the rising trend in numbers of caesareans, urgent improvements in the availability of general anaesthesia equipment and trained anaesthesia staff should be made to ensure the safety of caesareans. Initial efforts should focus on improving anaesthesia provision in public and faith-based organisation hospitals, which together perform more than 90% of all caesareans in Tanzania. PMID- 30287616 TI - Qualitative protocol for understanding the contribution of Australian policy in the urban planning, justice, energy and environment sectors to promoting health and health equity. AB - INTRODUCTION: A well-established body of literature demonstrates that health and equity are strongly influenced by the consequences of governments' policy and resultant actions (or inactions) outside the health sector. Consequently, the United Nations, and its agency the WHO, have called for national leadership and whole-of-government action to understand and address the health impacts of policies in all sectors. This research responds to that call by investigating how policymaking in four sectors-urban planning, justice, energy and environment-may influence the social determinants of health and health equity (SDH/HE). METHODS AND ANALYSIS: The research design is informed by a critical qualitative approach. Three successive stages are included in the design. The first involves analysing all strategic policy documents and selected legislative documents from the four sectors (n=583). The document analysis is based on a coding framework developed to identify alignment between the documents and the SDH/HE. Two policies that demonstrate good practice in regard to SDH/HE will be selected from each sector during the second stage for embedded case study analysis (total n=8). This is intended to illuminate which factors have supported recognition and action on SDH/HE in the selected policies. The third stage involves progressive theoretical integration and development to understand political and institutional facilitators and barriers to action on SDH/HE, both within and between sectors. ETHICS AND DISSEMINATION: The research will provide much needed evidence about how coherent whole-of-government action on SDH/HE can be advanced and contribute knowledge about how health-enhancing policy activity in the four sectors may be optimised. Learnings from the research will be shared via a project advisory group, policy briefings, academic papers, conference presentations and research symposia. Ethics approval has been secured for the embedded case studies, which involve research participants. PMID- 30287617 TI - Structural basis of the nucleosome transition during RNA polymerase II passage. AB - Genomic DNA forms chromatin, in which the nucleosome is the repeating unit. The mechanism by which RNA polymerase II (RNAPII) transcribes the nucleosomal DNA remains unclear. Here we report the cryo-electron microscopy structures of RNAPII nucleosome complexes in which RNAPII pauses at the superhelical locations SHL( 6), SHL(-5), SHL(-2), and SHL(-1) of the nucleosome. RNAPII pauses at the major histone-DNA contact sites, and the nucleosome interactions with the RNAPII subunits stabilize the pause. These structures reveal snapshots of nucleosomal transcription, in which RNAPII gradually tears DNA from the histone surface while preserving the histone octamer. The nucleosomes in the SHL(-1) complexes are bound to a "foreign" DNA segment, which might explain the histone transfer mechanism. These results provide the foundations for understanding chromatin transcription and epigenetic regulation. PMID- 30287619 TI - Reversible self-assembly of superstructured networks. AB - Soft structures in nature, such as protein assemblies, can organize reversibly into functional and often hierarchical architectures through noncovalent interactions. Molecularly encoding this dynamic capability in synthetic materials has remained an elusive goal. We report on hydrogels of peptide-DNA conjugates and peptides that organize into superstructures of intertwined filaments that disassemble upon the addition of molecules or changes in charge density. Experiments and simulations demonstrate that this response requires large-scale spatial redistribution of molecules directed by strong noncovalent interactions among them. Simulations also suggest that the chemically reversible structures can only occur within a limited range of supramolecular cohesive energies. Storage moduli of the hydrogels change reversibly as superstructures form and disappear, as does the phenotype of neural cells in contact with these materials. PMID- 30287618 TI - An autoimmune disease variant of IgG1 modulates B cell activation and differentiation. AB - The maintenance of autoreactive B cells in a quiescent state is crucial for preventing autoimmunity. Here we identify a variant of human immunoglobulin G1 (IgG1) with a Gly396->Arg substitution (hIgG1-G396R), which positively correlates with systemic lupus erythematosus. In induced lupus models, murine homolog Gly390 >Arg (G390R) knockin mice generate excessive numbers of plasma cells, leading to a burst of broad-spectrum autoantibodies. This enhanced production of antibodies is also observed in hapten-immunized G390R mice, as well as in influenza vaccinated human G396R homozygous carriers. This variant potentiates the phosphorylation of the IgG1 immunoglobulin tail tyrosine (ITT) motif. This, in turn, alters the availability of phospho-ITT to trigger longer adaptor protein Grb2 dwell times in immunological synapses, leading to hyper-Grb2-Bruton's tyrosine kinase (Btk) signaling upon antigen binding. Thus, the hIgG1-G396R variant is important for both lupus pathogenesis and antibody responses after vaccination.

PMID- 30287621 TI - Dyserythropoiesis evaluated by RED score and hepcidin/ferritin levels predicts response to erythropoietin in lower risk myelodysplastic syndromes. AB - Erythropoiesis-stimulating agents are generally the first line of treatment of anemia in lower risk myelodysplastic syndrome patients. We prospectively investigated the predictive value of somatic mutations, and biomarkers of ineffective erythropoiesis including flow cytometry RED score, serum GDF-15, and hepcidin levels. Inclusion criteria were: Erythropoiesis stimulating agents naive, IPSS low or intermediate-1 MDS with Hemoglobin level< 10g/dl, red blood cell transfusion-dependent or not. Patients received epoetin zeta 40 000 IU/week and erythroid response (IWG 2006 criteria) was assessed at week 12. Serum EPO level, iron parameters and hepcidin, flow cytometry Ogata and RED score, GDF-15, and molecular analysis by next-generation sequencing were determined at baseline. 70 patients were included. Median age was 78 years. There were 22 RCMD, 19 RCUD, 14 RARS, 4 RAEB-1, 6 CMML, 2 del 5q-, 3 unclassifiable, IPSS-R was 13 very low, 47 low, 9 intermediate and high. Twenty patients were transfusion dependent. Erythroid response was 48% and median response duration was 26 months. At baseline, non-responders had significantly higher RED score, lower hepcidin/ferritin ratio. In multivariate analysis, only RED score>4 (p=0.05) and hepcidin/ferritin<9 (p=0.02) were significantly associated with worse erythroid response. Median response duration was shorter in patients with GDF-15>2000 pg/ml and hepcidin/ferritin<9 (P=0.0008, and p=0.01, respectively). In multivariate analysis, both variables were associated with shorter response duration. Erythroid response to epoetin zeta was similar to that obtained with other erythropoiesis stimulating agents. It was correlated with higher baseline hepcidin/ferritin ratio and lower RED score. PMID- 30287622 TI - Oral ulcer due to dabigatran capsule.

PMID- 30287624 TI - Borderline Mucinous Testicular Tumour: Diagnostic and Management difficulties. AB - A 45-year-old man presented with right-sided testicular swelling and pain. An examination found a tender, firm right testis, a clinically normal left testis and no palpable lymphadenopathy. Tumour and inflammatory markers were within normal limits. A scrotal ultrasound scan showed an intratesticular, avascular lesion measuring 4.4*2.6*1.8 cm. A CT scan of his chest/abdomen/pelvis (CT C/A/P) showed no metastatic or primary lesions. An elective right-inguinal orchidectomy was subsequently performed. Histopathology showed a cystic mucinous tumour lined with intestinal-type epithelium. Differentials of metastatic adenocarcinoma, possibly of a gastrointestinal origin, a monodermal teratoma, or a borderline mucinous tumour of the testicle (BMTT) were considered. Following 12 p genetic studies and a colonoscopy, both of which found no abnormalities, a presumptive diagnosis of a BMTT was made. The patient is to have an annual urological review with a CT C/A/P and 5 yearly colonoscopies. PMID- 30287625 TI - Sarcoidosis and HIV infection in a native Saudi man. AB - Sarcoidosis is a rare condition among native Saudis. It typically presents with asymptomatic chest radiographs, exertional breathlessness and cough. The coexistence of sarcoidosis and HIV is also rare, and the overlap of the symptoms makes their differential diagnosis challenging. Nevertheless, the outcome of sarcoidosis is favourable with or without the presence of HIV. We present a case of a 55-year-old native Saudi man with extremely atypical sarcoidosis presentation coexisting with HIV. This case highlights the association between the two pathologies, and the difficulties encountered in establishing a proper diagnosis in the presence of two overlapping diseases. PMID- 30287626 TI - Cardiac arrest due to critical stenosis of a bicuspid aortic valve mimicking left main coronary artery occlusion on ECG. AB - A 49-year-old man presented to the emergency room after a cardiac arrest. On arrival, the patient's ECG showed ST-segment elevations in the aVR and anteroseptal leads with diffuse ST depression suggestive of left main coronary artery occlusion. Subsequent coronary catheterisation showed normal coronaries but revealed severe stenosis of his bicuspid aortic valve. A surgical replacement of the aortic valve was performed, and the patient recovered successfully. PMID- 30287627 TI - Hereditary angioedema: a mother diagnosing her child using Google as a diagnostic aid. AB - Hereditary angioedema (HAE), due to C1-inhibitor deficiency, is a rare autosomal dominant and potentially life-threatening disease characterised by recurrent oedema attacks of skin, mucosa and viscera. Due to the rarity and the fact that symptoms of HAE imitate other forms of angioedema and other conditions, HAE may be misdiagnosed, especially in emergency settings. Consequently, patients with HAE may experience significant delays in diagnosis. Without an accurate diagnosis patients with HAE may not receive proper treatment. At times 'Doctor Google' may be an important tool in establishing the diagnosis. The aim of this case report is to emphasise the importance of listening to patients and relatives and being humble to 'Doctor Google'. Furthermore, the aim is to remind all healthcare personal of HAE and the importance of considering the rare differential diagnoses to common symptoms.

PMID- 30287628 TI - Pericardial effusion as first presentation of disseminated non-Hodgkin's lymphoma. AB - A 46-year-old woman with quiescent lupus presented with worsening pleuritic chest pain and dyspnoea. Bedside echocardiogram confirmed large pericardial effusion with cardiac tamponade. Emergency bedside pericardiocentesis was performed. Pericardial fluid cytology confirmed diffuse large B cell lymphoma, stage four on positron emission tomography. Conventional rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone chemotherapy achieved good response in all sites except the pericardium. Progressive cardiac involvement was complicated by atrioventricular conduction block requiring permanent pacemaker. Second-line palliative chemotherapy was performed. PMID- 30287630 TI - Heart of the matter: reverse takotsubo syndrome in an anthracycline-exposed oncology patient. AB - A 24-year-old man with acute myelogenous leukaemia and a history of anthracycline treatment is hospitalised for non-anthracycline chemotherapy. He develops new onset heart failure requiring intesive care unit (ICU) admission during his stay. There is debate as to the aetiology of his heart failure, whether anthracycline cardiotoxicity or takotsubo syndrome. He is diuresed and discharged home with close follow-up. Ultimately, the retrospective use of two-dimensional speckle tracking echocardiography derived strain helps diagnose reverse takotsubo syndrome. PMID- 30287631 TI - A radiation belt of energetic protons located between Saturn and its rings. AB - Saturn has a sufficiently strong dipole magnetic field to trap high-energy charged particles and form radiation belts, which have been observed outside its rings. Whether stable radiation belts exist near the planet and inward of the rings was previously unknown. The Cassini spacecraft's Magnetosphere Imaging Instrument obtained measurements of a radiation belt that lies just above Saturn's dense atmosphere and is decoupled from the rest of the magnetosphere by the planet's A- to C-rings. The belt extends across the D-ring and comprises protons produced through cosmic ray albedo neutron decay and multiple charge exchange reactions. These protons are lost to atmospheric neutrals and D-ring dust. Strong proton depletions that map onto features on the D-ring indicate a highly structured and diverse dust environment near Saturn. PMID- 30287632 TI - The low-frequency source of Saturn's kilometric radiation. AB - Understanding how auroral radio emissions are produced by magnetized bodies requires in situ measurements within their source region. Saturn's kilometric radiation (SKR) has been widely used as a remote proxy of Saturn's magnetosphere. We present wave and plasma measurements from the Cassini spacecraft during its ring-grazing high-inclination orbits, which passed three times through the high altitude SKR emission region. Northern dawn-side, narrow-banded radio sources were encountered at frequencies of 10 to 20 kilohertz, within regions of upward currents mapping to the ultraviolet auroral oval. The kilometric waves were produced on the extraordinary mode by the cyclotron maser instability from 6- to 12-kilo-electron volt electron beams and radiated quasi-perpendicularly to the auroral magnetic field lines. The SKR low-frequency sources appear to be strongly controlled by time-variable magnetospheric electron densities. PMID- 30287633 TI - Dust grains fall from Saturn's D-ring into its equatorial upper atmosphere. AB - The sizes of Saturn's ring particles range from meters (boulders) to nanometers (dust). Determination of the rings' ages depends on loss processes, including the transport of dust into Saturn's atmosphere. During the Grand Finale orbits of the Cassini spacecraft, its instruments measured tiny dust grains that compose the innermost D-ring of Saturn. The nanometer-sized dust experiences collisions with exospheric (upper atmosphere) hydrogen and molecular hydrogen, which forces it to fall from the ring into the ionosphere and lower atmosphere. We used the Magnetospheric Imaging Instrument to detect and characterize this dust transport and also found that diffusion dominates above and near the altitude of peak ionospheric density. This mechanism results in a mass deposition into the equatorial atmosphere of ~5 kilograms per second, constraining the age of the D ring. PMID- 30287634 TI - Chemical interactions between Saturn's atmosphere and its rings. AB - The Pioneer and Voyager spacecraft made close-up measurements of Saturn's ionosphere and upper atmosphere in the 1970s and 1980s that suggested a chemical interaction between the rings and atmosphere. Exploring this interaction provides information on ring composition and the influence on Saturn's atmosphere from infalling material. The Cassini Ion Neutral Mass Spectrometer sampled in situ the region between the D ring and Saturn during the spacecraft's Grand Finale phase. We used these measurements to characterize the atmospheric structure and material influx from the rings. The atmospheric He/H2 ratio is 10 to 16%. Volatile compounds from the rings (methane; carbon monoxide and/or molecular nitrogen), as well as larger organic-bearing grains, are flowing inward at a rate of 4800 to 45,000 kilograms per second. PMID- 30287635 TI - In situ collection of dust grains falling from Saturn's rings into its atmosphere. AB - Saturn's main rings are composed of >95% water ice, and the nature of the remaining few percent has remained unclear. The Cassini spacecraft's traversals between Saturn and its innermost D ring allowed its cosmic dust analyzer (CDA) to collect material released from the main rings and to characterize the ring material infall into Saturn. We report the direct in situ detection of material from Saturn's dense rings by the CDA impact mass spectrometer. Most detected grains are a few tens of nanometers in size and dynamically associated with the previously inferred "ring rain." Silicate and water-ice grains were identified, in proportions that vary with latitude. Silicate grains constitute up to 30% of infalling grains, a higher percentage than the bulk silicate content of the rings. PMID- 30287637 TI - Renewable energy for Puerto Rico. PMID- 30287636 TI - Saturn's magnetic field revealed by the Cassini Grand Finale. AB - During 2017, the Cassini fluxgate magnetometer made in situ measurements of Saturn's magnetic field at distances ~2550 +/- 1290 kilometers above the 1-bar surface during 22 highly inclined Grand Finale orbits. These observations refine the extreme axisymmetry of Saturn's internal magnetic field and show displacement of the magnetic equator northward from the planet's physical equator. Persistent small-scale magnetic structures, corresponding to high-degree (>3) axisymmetric magnetic moments, were observed. This suggests secondary shallow dynamo action in the semiconducting region of Saturn's interior. Some high-degree magnetic moments could arise from strong high-latitude concentrations of magnetic flux within the planet's deep dynamo. A strong field-aligned current (FAC) system is located between Saturn and the inner edge of its D-ring, with strength comparable to the high-latitude auroral FACs.

PMID- 30287655 TI - Glacial lake outburst floods as drivers of fluvial erosion in the Himalaya. AB - Himalayan rivers are frequently hit by catastrophic floods that are caused by the failure of glacial lake and landslide dams; however, the dynamics and long-term impacts of such floods remain poorly understood. We present a comprehensive set of observations that capture the July 2016 glacial lake outburst flood (GLOF) in the Bhotekoshi/Sunkoshi River of Nepal. Seismic records of the flood provide new insights into GLOF mechanics and their ability to mobilize large boulders that otherwise prevent channel erosion. Because of this boulder mobilization, GLOF impacts far exceed those of the annual summer monsoon, and GLOFs may dominate fluvial erosion and channel-hillslope coupling many tens of kilometers downstream of glaciated areas. Long-term valley evolution in these regions may therefore be driven by GLOF frequency and magnitude, rather than by precipitation. PMID- 30287656 TI - Rapid change of superconductivity and electron-phonon coupling through critical doping in Bi-2212. AB - Electron-boson coupling plays a key role in superconductivity for many systems. However, in copper-based high-critical temperature (T c) superconductors, its relation to superconductivity remains controversial despite strong spectroscopic fingerprints. In this study, we used angle-resolved photoemission spectroscopy to find a pronounced correlation between the superconducting gap and the bosonic coupling strength near the Brillouin zone boundary in Bi2Sr2CaCu2O8+delta The bosonic coupling strength rapidly increases from the overdoped Fermi liquid regime to the optimally doped strange metal, concomitant with the quadrupled superconducting gap and the doubled gap-to-T c ratio across the pseudogap boundary. This synchronized lattice and electronic response suggests that the effects of electronic interaction and the electron-phonon coupling (EPC) reinforce each other in a positive-feedback loop upon entering the strange-metal regime, which in turn drives a stronger superconductivity. PMID- 30287657 TI - Quantifying hot carrier and thermal contributions in plasmonic photocatalysis. AB - Photocatalysis based on optically active, "plasmonic" metal nanoparticles has emerged as a promising approach to facilitate light-driven chemical conversions under far milder conditions than thermal catalysis. However, an understanding of the relation between thermal and electronic excitations has been lacking. We report the substantial light-induced reduction of the thermal activation barrier for ammonia decomposition on a plasmonic photocatalyst. We introduce the concept of a light-dependent activation barrier to account for the effect of light illumination on electronic and thermal excitations in a single unified picture. This framework provides insight into the specific role of hot carriers in plasmon mediated photochemistry, which is critically important for designing energy efficient plasmonic photocatalysts. PMID- 30287658 TI - Rapid Pliocene adaptive radiation of modern kangaroos. AB - Differentiating between ancient and younger, more rapidly evolved clades is important for determining paleoenvironmental drivers of diversification. Australia possesses many aridity-adapted lineages, the origins of which have been closely linked to late Miocene continental aridification. Using dental macrowear and molar crown height measurements, spanning the past 25 million years, we show that the most iconic Australian terrestrial mammals, "true" kangaroos (Macropodini), adaptively radiated in response to mid-Pliocene grassland expansion rather than Miocene aridity. In contrast, low-crowned, short-faced kangaroos radiated into predominantly browsing niches as the late Cenozoic became more arid, contradicting the view that this was an interval of global browser decline. Our results implicate warm-to-cool climatic oscillations as a trigger for adaptive radiation and refute arguments attributing Pleistocene megafaunal extinction to aridity-forced dietary change. PMID- 30287659 TI - Urbanization and humidity shape the intensity of influenza epidemics in U.S. cities. AB - Influenza epidemics vary in intensity from year to year, driven by climatic conditions and by viral antigenic evolution. However, important spatial variation remains unexplained. Here we show predictable differences in influenza incidence among cities, driven by population size and structure. Weekly incidence data from 603 cities in the United States reveal that epidemics in smaller cities are focused on shorter periods of the influenza season, whereas in larger cities, incidence is more diffuse. Base transmission potential estimated from city-level incidence data is positively correlated with population size and with spatiotemporal organization in population density, indicating a milder response to climate forcing in metropolises. This suggests that urban centers incubate critical chains of transmission outside of peak climatic conditions, altering the spatiotemporal geometry of herd immunity. PMID- 30287661 TI - The role of education interventions in improving economic rationality. AB - Schooling rewards people with labor market returns and nonpecuniary benefits in other realms of life. However, there is no experimental evidence showing that education interventions improve individual economic rationality. We examine this hypothesis by studying a randomized 1-year financial support program for education in Malawi that reduced absence and dropout rates and increased scores on a qualification exam of female secondary school students. We measure economic rationality 4 years after the intervention by using lab-in-the-field experiments to create scores of consistency with utility maximization that are derived from revealed preference theory. We find that students assigned to the intervention had higher scores of rationality. The results remain robust after controlling for changes in cognitive and noncognitive skills. Our results suggest that education enhances the quality of economic decision-making. PMID- 30287663 TI - More than my publications. PMID- 30287662 TI - Reprogramming normal human epithelial tissues to a common, lethal neuroendocrine cancer lineage. AB - The use of potent therapies inhibiting critical oncogenic pathways active in epithelial cancers has led to multiple resistance mechanisms, including the development of highly aggressive, small cell neuroendocrine carcinoma (SCNC). SCNC patients have a dismal prognosis due in part to a limited understanding of the molecular mechanisms driving this malignancy and the lack of effective treatments. Here, we demonstrate that a common set of defined oncogenic drivers reproducibly reprograms normal human prostate and lung epithelial cells to small cell prostate cancer (SCPC) and small cell lung cancer (SCLC), respectively. We identify shared active transcription factor binding regions in the reprogrammed prostate and lung SCNCs by integrative analyses of epigenetic and transcriptional landscapes. These results suggest that neuroendocrine cancers arising from distinct epithelial tissues may share common vulnerabilities that could be exploited for the development of drugs targeting SCNCs. PMID- 30287660 TI - Impacts of species richness on productivity in a large-scale subtropical forest experiment. AB - Biodiversity experiments have shown that species loss reduces ecosystem functioning in grassland. To test whether this result can be extrapolated to forests, the main contributors to terrestrial primary productivity, requires large-scale experiments. We manipulated tree species richness by planting more than 150,000 trees in plots with 1 to 16 species. Simulating multiple extinction scenarios, we found that richness strongly increased stand-level productivity. After 8 years, 16-species mixtures had accumulated over twice the amount of carbon found in average monocultures and similar amounts as those of two commercial monocultures. Species richness effects were strongly associated with functional and phylogenetic diversity. A shrub addition treatment reduced tree productivity, but this reduction was smaller at high shrub species richness. Our results encourage multispecies afforestation strategies to restore biodiversity and mitigate climate change. PMID- 30287664 TI - Impact of workplace violence and compassionate behaviour in hospitals on stress, sleep quality and subjective health status among Chinese nurses: a cross sectional survey. AB - OBJECTIVES: The aim of this study is to describe the current state of workplace violence (WPV) and compassionate behaviour towards nurses and to explain how they affect nurses' stress, sleep quality and subjective health status. DESIGN: A cross-sectional online survey study. SETTING: The survey was conducted across eight provinces in China. PARTICIPANTS: A total of 1024 nurses were recruited to complete an online questionnaire survey from February to May 2016 in China. RESULTS: Approximately 75.4% participants had experienced some form of violence. Most of the participants experienced WPV such as verbal violence (65.2%), made difficulties (54.5%), tarnished reputation (37.5%), mob behaviour (34.9%), intimidation behaviour (18.8%), physical violence (14.6%) and sexual harassment (5.9%). In this study, 92.4% participants experienced compassionate behaviour from their coworkers (84.9%), supervisors (67.3%), and from their patients (65.3%). The results show that the exposure to WPV behaviour significantly affected the psychological stress (beta=0.295, p<0.01), sleep quality (beta= 0.198, p<0.01) and subjective health status (beta=-0.252, p<0.01) of nurses. The exposure to compassionate behaviour significantly affected the psychological stress (beta=-0.229, p<0.01), sleep quality (beta=0.326, p<0.01) and subjective health status (beta=0.342, p<0.01) of nurses. The results of the mediation analysis showed that psychological stress is a partial mediator in the relationship between violence and sleep quality (beta=-0.458, p<0.01) and between violence and subjective health (beta=-0.425, p<0.01). Moreover, psychological stress also partially mediated the relationship between compassionate behaviour and sleep quality (beta=-0.473, p<0.01), and between compassionate behaviour and subjective health (beta=-0.405, p<0.01). CONCLUSION: In China, most nurses have experienced different forms of WPV from patients and/or their relatives, as well as experiencing various forms of compassionate behaviour from their coworkers, supervisors and/or patients. This study investigates the prevalence of the different types of WPV and compassionate behaviour. Several aspects of harm to nurses from exposure to violence is confirmed. We found that WPV can damage nurses' health outcomes, while compassionate behaviours were beneficial to their health outcomes. A harmonious nursing environment should be provided to minimise threats to nurses' health status. PMID- 30287665 TI - Practice of informed consent in Guangdong, China: a qualitative study from the perspective of in-hospital patients. AB - OBJECTIVE: This study aimed to investigate the practice of informed consent in China from the perspective of patients. DESIGN: A qualitative study using in depth interviews with in-hospital patients focusing on personal experience with informed consent. SETTING: Guangdong Province, China. PARTICIPANTS: 71 in hospital patients in rehabilitation after surgical operations were included. RESULTS: Medical information is not actively conveyed by doctors nor effectively received by patients. Without complete and understandable information, patients are unable to make an autonomous clinical decision but must sign an informed consent form following the doctor's medical arrangement. Three barriers to accessing medical information by patients were identified: (1) medical information received by patients was insufficient to support their decision making, (2) patients lacked medical knowledge to understand the perceptions of doctors and (3) patient-doctor interactions were insufficient in clinical settings. CONCLUSIONS: Informed consent is implemented as an administrative procedure at the hospital level in China. However, it has not been embedded in doctors' clinical practices because, from the perspective of patients, doctors do not fulfil the obligation of medical information provision. As a result, the informed part of informed consent was neglected by individual doctors in China. Reforming medical education, monitoring the process of informed consent in clinical settings and redesigning medical institutional arrangements are pathways to restoring the practice of informed consent and patient-centred models in China. PMID- 30287666 TI - Socioeconomic position, symptoms of depression and subsequent mental healthcare treatment: a Danish register-based 6-month follow-up study on a population survey. AB - OBJECTIVE: Examine whether the severity of symptoms of depression was associated with the type of mental healthcare treatment (MHCT) received, independent of socioeconomic position (SEP). DESIGN: Register-based 6-month follow-up study on participants from the Danish General Suburban Population Study (GESUS) 2010-2013, who scored the Major Depression Inventory (MDI). PARTICIPANTS: Nineteen thousand and eleven respondents from GESUS. INTERVENTIONS: The MHCT of the participants was tracked in national registers 4 months prior and 6 months after their MDI scores. MHCT was graduated in levels. SEP was defined by years of formal postsecondary education and income categorised into three levels. Data were analysed using logistic and Poisson regression analyses. OUTCOMES: MHCT included number of contacts with: general practitioner (GP), GP mental health counselling, psychologist, psychiatrist, emergency contacts, admissions to psychiatric hospitals and prescriptions of antidepressants. RESULTS: For 547 respondents with moderate to severe symptoms of depression there was no difference across SEP in use of services, contact (y/n), frequency of contact or level of treatment, except respondents with low SEP had more frequent contact with their GP. However, of the 547 respondents , 10% had no treatment contacts at all, and 47% had no treatment beyond GP consultation. Among respondents with no/few symptoms of depression, postsecondary education >=3 years was associated with more contact with specialised services (adjusted OR (aOR) 1.92; 95% CI 1.18 to 3.13); however, this difference did not apply for income; additionally, high SEP was associated with fewer prescriptions of antidepressants (education aOR 0.69; CI 0.50 to 0.95; income aOR 0.56, CI 0.39 to 0.80) compared with low SEP. CONCLUSION: Participants with symptoms of depression were treated according to the severity of their symptoms, independent of SEP; however, more than half with moderate to severe symptoms received no treatment beyond GP consultation. People in low SEP and no/few symptoms of depression were more often treated with antidepressants. The study was approved by The Danish Data Protection Agency Journal number 2015-41 3984.

PMID- 30287667 TI - Effect of national HIV testing recommendations and local interventions on HIV testing practices in a Swiss university hospital: a retrospective analysis between 2012 and 2015. AB - OBJECTIVES: Despite HIV testing recommendations published by the Federal Office of Public Health (FOPH) since 2007, many individuals living with HIV are diagnosed late in Switzerland. The aim of this study is to examine the effect of the 2013 FOPH HIV testing recommendations on HIV testing rates. SETTING: Ten clinical services at Lausanne University Hospital, Lausanne, Switzerland. PARTICIPANTS: Patients attending between 1 January 2012 and 31 December 2015. DESIGN: Retrospective analysis using two existing hospital databases. HIV testing rates calculated as the percentage of tests performed (from the Immunology Service database) per number of patients seen (from the central hospital database). PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was testing rate change following the 2013 FOPH testing recommendations, comparing testing rates 2 years before and 2 years after their publication. Secondary outcomes were demographic factors of patients tested or not tested for HIV. RESULTS: 147 884 patients were seen during the study period of whom 9653 (6.5%) were tested for HIV, with 34 new HIV diagnoses. Mean testing rate increased from 5.6% to 7.8% after the recommendations (p=0.001). Testing rate increases were most marked in services involved in clinical trials on HIV testing, whose staff had attended training seminars on testing indications and practice. Testing rates were lower among older (aged >50 years), female and Swiss patients compared with younger, male and non-Swiss patients, both globally (p=0.001) and in specific clinical services. CONCLUSIONS: This simple two-database tool demonstrates clinical services in which HIV testing practice can be optimised. Improved testing rates in services involved in clinical trials on testing suggest that local engagement complements the effect of national recommendations. While, overall, HIV testing rates increased significantly over time, testing rates were lower among patients with similar demographic profiles to individuals diagnosed late in Switzerland. PMID- 30287668 TI - Smoking as a risk factor for lung cancer in women and men: a systematic review and meta-analysis. AB - OBJECTIVES: To investigate the sex-specific association between smoking and lung cancer. DESIGN: Systematic review and meta-analysis. DATA SOURCES: We searched PubMed and EMBASE from 1 January 1999 to 15 April 2016 for cohort studies. Cohort studies before 1 January 1999 were retrieved from a previous meta-analysis. Individual participant data from three sources were also available to supplement analyses of published literature. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Cohort studies reporting the sex-specific relative risk (RR) of lung cancer associated with smoking. RESULTS: Data from 29 studies representing 99 cohort studies, 7 million individuals and >50 000 incident lung cancer cases were included. The sex-specific RRs and their ratio comparing women with men were pooled using random-effects meta-analysis with inverse-variance weighting. The pooled multiple-adjusted lung cancer RR was 6.99 (95% Confidence Interval (CI) 5.09 to 9.59) in women and 7.33 (95% CI 4.90 to 10.96) in men. The pooled ratio of the RRs was 0.92 (95% CI 0.72 to 1.16; I2=89%; p<0.001), with no evidence of publication bias or differences across major pre-defined participant and study subtypes. The women-to-men ratio of RRs was 0.99 (95% CI 0.65 to 1.52), 1.11 (95% CI 0.75 to 1.64) and 0.94 (95% CI 0.69 to 1.30), for light, moderate and heavy smoking, respectively. CONCLUSIONS: Smoking yields similar risks of lung cancer in women compared with men. However, these data may underestimate the true risks of lung cancer among women, as the smoking epidemic has not yet reached full maturity in women. Continued efforts to measure the sex-specific association of smoking and lung cancer are required. PMID- 30287669 TI - Acceptance and Commitment Therapy for Muscle Disease (ACTMus): protocol for a two arm randomised controlled trial of a brief guided self-help ACT programme for improving quality of life in people with muscle diseases. AB - INTRODUCTION: In adults, muscle disease (MD) is often a chronic long-term condition with no definitive cure. It causes wasting and weakness of the muscles resulting in a progressive decline in mobility, alongside other symptoms, and is typically associated with reduced quality of life (QoL). Previous research suggests that a psychological intervention, and in particular Acceptance and Commitment Therapy (ACT), may help improve QoL in MD. ACT is a newer type of cognitive behavioural treatment that aims to improve QoL by virtue of improvement in a process called psychological flexibility. The primary aim of this randomised controlled trial (RCT) is to evaluate the efficacy of a guided self-help ACT programme for improving QoL in people with MD. Main secondary outcomes are mood, symptom impact, work and social adjustment and function at 9-week follow-up. METHODS AND ANALYSIS: Acceptance and Commitment Therapy for Muscle Disease is an assessor-blind, multicentre, two-armed, parallel-group RCT to assess the efficacy of ACT plus standard medical care (SMC) compared with SMC alone. Individuals with a diagnosis of one of four specific MDs, with a duration of at least 6 months and with mild to moderate anxiety or depression (Hospital Anxiety and Depression Scale score >=8) will be recruited from UK-based MD clinics and MD patient support organisations. Participants will be randomised to either ACT plus SMC or SMC alone by an independent randomisation service. Participants will be followed up at 3, 6 and 9 weeks. Analysis will be intention to treat, conducted by the trial statistician who will be blinded to treatment allocation. ETHICS AND DISSEMINATION: The study has received full ethical approval. Study results will be disseminated via peer-reviewed publications, conference presentations and journal articles. Data obtained from the trial will enable clinicians and health service providers to make informed decisions regarding the efficacy of ACT for improving QoL for patients with MD. TRIAL REGISTRATION NUMBER: NCT02810028. PROTOCOL VERSION: V.11 (4 April 2017). PMID- 30287670 TI - Research protocol for the exploration of experiences of Aboriginal Australian mothers and healthcare professionals when using the Edinburgh Postnatal Depression Scale: a process-oriented validation study using triangulated participatory mixed methods. AB - INTRODUCTION: Adopting a process-oriented framework for test validation can help to establish whether this tool has the potential to be an acceptable, valid and reliable indicator of depression for mothers and mothers-to-be. This mixed methods research protocol seeks to explore the views and experiences of Aboriginal mothers and healthcare professionals in relation to the Edinburgh Postnatal Depression Scale (EPDS), and is intended to highlight potential barriers in perinatal mental health conceptualisation, engagement and response style. METHODS AND ANALYSIS: Thematic analysis will be applied to interview transcripts of Aboriginal Australian mothers (n=6+) and healthcare professionals (n=6+) to identify key themes. The process-focused validation model will use narratives about experiences of using the EPDS as the priority point of analysis. Item-level data and process-level (experience) data are key phenomenological data. The interview-based narratives will be then compared with EPDS scores to check for points of congruence and divergence. This will be done at two time points, antenatally and postnatally, to assess changes in assessment processes and perceptions. Bridging evidence-based research with clinical practice in an Aboriginal Australian context will be facilitated by an investigation of the perceived cultural relevance and likely clinical effectiveness of EPDS. Such evidence is critical to understanding whether the EPDS fulfils its intended purpose. The guiding principles in designing this research protocol is to benefit the well-being of young Aboriginal families and communities through partnership with Aboriginal women. ETHICS AND DISSEMINATION: Ethics approval was obtained from Human Research Ethics Committee of Murdoch University and from Western Australian Aboriginal Health Ethics Committee (WAAHEC). Participating healthcare sites and services have provided letters of support. Results of this study will be submitted for publication in a peer-reviewed journal. PMID- 30287671 TI - Glimepiride monotherapy versus combination of glimepiride and linagliptin therapy in patients with HNF1A-diabetes: a protocol for a randomised, double-blinded, placebo-controlled trial. AB - INTRODUCTION: Hepatocyte nuclear factor 1alpha (HNF1A)-diabetes is the most common monogenetic subtype of diabetes. Strict glycaemic control is crucial for a good prognosis for patients with HNF1A-diabetes. Sulfonylurea (SU) is used as a first-line therapy in HNF1A-diabetes. However, SU therapy may be problematic as it confers a high risk of hypoglycaemia. We hypothesise that low dose of SU in combination with a dipeptidyl peptidase 4 inhibitor provides a safer and more efficacious treatment in patients with HNF1A-diabetes compared with SU as monotherapy. METHODS AND ANALYSIS: In a randomised, double-blinded, crossover study, patients with HNF1A-diabetes will randomly be assigned to 16 weeks of treatment with glimepiride+linagliptin, 4 weeks of washout and 16 weeks of treatment with glimepiride+placebo (or vice versa). Treatment will be evaluated with continuous glucose monitoring and combined meal and bicycle tests conducted at baseline and at the end of each of the two treatment periods. The primary end point is the absolute difference in the mean amplitude of glycaemic excursions between the two treatments (glimepiride+linagliptin vs glimepiride+placebo) at the end of each treatment period. ETHICS AND DISSEMINATION: The study protocol is approved by the Danish Medicines Agency, The Scientific-Ethical Committee of the Capital Region of Denmark (H-17014518) and the Danish Data Protection Agency. The trial will be carried out and monitored in compliance with Good Clinical Practice guidelines and in accordance with the latest version of the Declaration of Helsinki. Positive, negative and inconclusive results will be published at scientific conferences and as one or more scientific manuscripts in peer-reviewed journals with authorship in accordance with the International Committee of Medical Journal Editors' recommendations. TRIAL REGISTRATION NUMBER: 2017-000204 15. PMID- 30287672 TI - Twenty-year time trends in hypertension prevalence in Yi people of China: three successive cross-sectional studies, 1996-2015. AB - OBJECTIVE: To explore the trend of hypertension prevalence and related factors in Yi people from 1996 to 2015. METHODS: Three successive cross-sectional surveys were conducted in Liangshan Yi Autonomous Prefecture in 1996, 2007 and 2015, respectively. A total of 8448 participants aged 20-80 years (5040 Yi farmers, 3408 Yi migrants) were included in final analysis. RESULTS: Overall, the age standardised prevalence of hypertension in migrants was significantly higher than in farmers. Furthermore, the age-standardised prevalence rates increased from 10.1% to 15.3% to 19.6% in Yi migrants and from 4.0% to 6.3% to 13.1% in Yi farmers during 1996 to 2007 to 2015. The highest 2015-to-1996 ratio of age standardised hypertension prevalence was in male farmers (ratio=4.30), whereas despite the highest prevalence of hypertension, the equivalent figure in male migrants was 1.57. The older age, overweight and obesity were persistent risk factors of hypertension in three periods. After adjusted for age and body mass index, the difference of hypertension prevalence between 1996 and 2015 then vanished in male migrants (OR=1.335; 95% CI: 0.884 to 2.015) and female farmers (OR=1.267; 95% CI: 0.590 to 2.719). The disparities of hypertension prevalence between Yi migrants and farmers were not statistically significant in all subgroups when adjusted for age, body mass index and education. CONCLUSIONS: Over the past two decades, the hypertension prevalence in Yi people has significantly increased. Yi migrants were more likely to be hypertensive than Yi farmers which was predominantly driven by the discrepancy of body mass index between them. PMID- 30287673 TI - Study protocol for an observational register-based study on health and risk factors in patients with hip and knee osteoarthritis. AB - INTRODUCTION: Hip and knee osteoarthritis is a leading cause of disability worldwide. Currently, the course of deterioration in pain and physical functioning in individuals with osteoarthritis is difficult to predict. Factors such as socioeconomic status and comorbidity contribute to progression of osteoarthritis, but clear associations have not been established. There is a need for early identification of individuals with slow disease development and a good prognosis, and those that should be recommended for future joint replacement surgery. METHODS AND ANALYSIS: This nationwide register-based study will use data for approximately 75 000 patients who sought and received core treatment for osteoarthritis in primary healthcare, and were registered in the Swedish population-based National Quality Register for Better Management of Patients with Osteoarthritis. These data will be merged with data for replacement surgery, socioeconomic factors, healthcare consumption and comorbidity from the Swedish Hip Arthroplasty Register, the Swedish Knee Arthroplasty Register, Statistics Sweden and the National Board of Health and Welfare, Sweden. The linkage will be performed using personal identity numbers that are unique to all citizens in Sweden. ETHICS AND DISSEMINATION: The study was approved by the Regional Ethical Review Board in Gothenburg, Sweden (dnr 1059-16). The results from this study will be submitted to peer-reviewed journals and reported at suitable national and international meetings. TRIAL REGISTRATION NUMBER: NCT03438630. PMID- 30287674 TI - Research priorities in fragility fractures of the lower limb and pelvis: a UK priority setting partnership with the James Lind Alliance. AB - OBJECTIVE: To determine research priorities in fragility fractures of the lower limb and pelvis which represent the shared priorities of patients, their friends and families, carers and healthcare professionals. DESIGN/SETTING: A national (UK) research priority setting partnership. PARTICIPANTS: Patients over 60 years of age who have experienced a fragility fracture of the lower limb or pelvis; carers involved in their care (both in and out of hospital); family and friends of patients; healthcare professionals involved in the treatment of these patients including but not limited to surgeons, anaesthetists, paramedics, nurses, general practitioners, physicians, physiotherapists and occupational therapists. METHODS: Using a multiphase methodology in partnership with the James Lind Alliance over 18 months (August 2016-January 2018), a national scoping survey asked respondents to submit their research uncertainties. These were amalgamated into a smaller number of research questions. The existing evidence was searched to ensure that the questions had not been answered. A second national survey asked respondents to prioritise the research questions. A final shortlist of 25 questions was taken to a multistakeholder workshop where a consensus was reached on the top 10 priorities. RESULTS: There were 963 original uncertainties submitted by 365 respondents to the first survey. These original uncertainties were refined into 88 research questions of which 76 were judged to be true uncertainties following a review of the research evidence. Healthcare professionals and other stakeholders (patients, carers, friends and families) were represented equally in the responses. The top 10 represent uncertainties in rehabilitation, pain management, anaesthesia and surgery. CONCLUSIONS: We report the top 10 UK research priorities in patients with fragility fractures of the lower limb and pelvis. The priorities highlight uncertainties in rehabilitation, postoperative physiotherapy, pain, weight-bearing, infection and thromboprophylaxis. The challenge now is to refine and deliver answers to these research priorities. PMID- 30287675 TI - General practitioners and emergency departments (GPED)-efficient models of care: a mixed-methods study protocol. AB - INTRODUCTION: Pressure continues to grow on emergency departments in the UK and throughout the world, with declining performance and adverse effects on patient outcome, safety and experience. One proposed solution is to locate general practitioners to work in or alongside the emergency department (GPED). Several GPED models have been introduced, however, evidence of effectiveness is weak. This study aims to evaluate the impact of GPED on patient care, the primary care and acute hospital team and the wider urgent care system. METHODS AND ANALYSIS: The study will be divided into three work packages (WPs). WP-A; Mapping and Taxonomy: mapping, description and classification of current models of GPED in all emergency departments in England and interviews with key informants to examine the hypotheses that underpin GPED. WP-B; Quantitative Analysis of National Data: measurement of the effectiveness, costs and consequences of the GPED models identified in WP-A, compared with a no-GPED model, using retrospective analysis of Hospital Episode Statistics Data. WP-C; Case Studies: detailed case studies of different GPED models using a mixture of qualitative and quantitative methods including: non-participant observation of clinical care, semistructured interviews with staff, patients and carers; workforce surveys with emergency department staff and analysis of available local routinely collected hospital data. Prospective case study sites will be identified by completing telephone interviews with sites awarded capital funding by the UK government to implement GPED initiatives. The study has a strong patient and public involvement group that has contributed to study design and materials, and which will be closely involved in data interpretation and dissemination. ETHICS AND DISSEMINATION: The study has been approved by the National Health Service East Midlands-Leicester South Research Ethics Committee: 17/EM/0312. The results of the study will be disseminated through peer-reviewed journals, conferences and a planned programme of knowledge mobilisation. TRIAL REGISTRATION NUMBER: ISRCTN51780222. PMID- 30287677 TI - Diagnosing male infertility. PMID- 30287676 TI - Financial Incentives to Increase Uptake of Pediatric HIV Testing (FIT): study protocol for a randomised controlled trial in Kenya. AB - INTRODUCTION: Index case testing (ICT) to identify HIV-infected children is efficient but has suboptimal uptake. Financial incentives (FI) have overcome financial barriers in other populations by offsetting direct and indirect costs. A pilot study found FI to be feasible for motivating paediatric ICT among HIV infected female caregivers. This randomised trial will determine the effectiveness of FI to increase uptake of paediatric ICT. METHODS AND ANALYSIS: The Financial Incentives to Increase Uptake of Pediatric HIV Testing trial is a five-arm, unblinded, randomised controlled trial that determines whether FI increases timely uptake of paediatric ICT. The trial will be conducted in multiple public health facilities in western Kenya. Each HIV-infected adult enrolled in HIV care will be screened for eligibility: primary caregiver to one or more children of unknown HIV status aged 0-12 years. Eligible caregivers will be individually randomised at the time of recruitment in equal 1:1:1:1:1 allocation to one of five arms (US$0 (control), US$1.25, US$2.50, US$5.00 and US$10.00). The trial aims to randomise 800 caregivers. Incentives will be disbursed at the time of child HIV testing using mobile money transfer or cash. Arms will be compared in terms of the proportion of adults who complete testing for at least one child within 2 months of randomisation and time to testing. A cost-effectiveness analysis of FI for paediatric ICT will also be conducted. ETHICS AND DISSEMINATION: This study was reviewed and approved by the University of Washington Institutional Review Board and the Kenyatta National Hospital Ethics and Research Committee. Trial results will be disseminated to healthcare workers at study sites, regional and national policymakers, and with patient populations at study sites (regardless of enrolment in the trial). Randomised trials of caregiver-child FI interventions pose unique study design, ethical and operational challenges, detailed here as a resource for future investigations. TRIAL REGISTRATION NUMBER: NCT03049917; Pre-results. PMID- 30287678 TI - Synthetic DNA-Encoded Monoclonal Antibody Delivery of Anti-CTLA-4 Antibodies Induces Tumor Shrinkage In Vivo. AB - Antibody-based immune therapies targeting the T-cell checkpoint molecules CTLA-4 and PD-1 have affected cancer therapy. However, this immune therapy requires complex manufacturing and frequent dosing, limiting the global use of this treatment. Here, we focused on the development of a DNA-encoded monoclonal antibody (DMAb) approach for delivery of anti-CTLA-4 monoclonal antibodies in vivo With this technology, engineered and formulated DMAb plasmids encoding IgG inserts were directly injected into muscle and delivered intracellularly by electroporation, leading to in vivo expression and secretion of the encoded IgG. DMAb expression from a single dose can continue for several months without the need for repeated administration. Delivery of an optimized DMAb encoding anti mouse CTLA-4 IgG resulted in high serum levels of the antibody as well as tumor regression in Sa1N and CT26 tumor models. DNA-delivery of the anti-human CTLA-4 antibodies ipilimumab and tremelimumab in mice achieved potent peak levels of approximately 85 and 58 MUg/mL, respectively. These DMAb exhibited prolonged expression, with maintenance of serum levels at or above 15 MUg/mL for over a year. Anti-human CTLA-4 DMAbs produced in vivo bound to human CTLA-4 protein expressed on stimulated human peripheral blood mononuclear cells and induced T cell activation in a functional assay ex vivo In summary, direct in vivo expression of DMAb encoding checkpoint inhibitors serves as a novel tool for immunotherapy that could significantly improve availability and provide broader access to such therapies.Significance: DNA-encoded monoclonal antibodies represent a novel technology for delivery and expression of immune checkpoint blockade antibodies, thus expanding patient access to, and possible clinical applications of, these therapies.

AB - The degradation of misfolded proteins is essential for cellular homeostasis. Misfolded proteins are normally degraded by the ubiquitin-proteasome system (UPS), and selective autophagy serves as a backup mechanism when the UPS is overloaded. Selective autophagy mediates the degradation of harmful material by its sequestration within double-membrane organelles called autophagosomes. The selectivity of autophagic processes is mediated by cargo receptors, which link the cargo to the autophagosomal membrane. The p62 cargo receptor (SQSTM1) has a main function during the degradation of misfolded, ubiquitylated proteins by selective autophagy; here it functions to phase separate these proteins into larger condensates and tether them to the autophagosomal membrane. Recent work has given us crucial insights into the mechanism of action of the p62 cargo receptor during selective autophagy and how its activity can be integrated with the UPS. We will discuss these recent insights in the context of protein quality control and the emerging concept of cellular organization mediated by phase transitions. PMID- 30287679 TI - Recurrent back pain during working life and exit from paid employment: a 28-year follow-up of the Whitehall II Study. AB - OBJECTIVES: To examine the impact of recurrent, as compared with single, reports of back pain on exit from paid employment over decades of follow-up. METHODS: The study sample was from the British Whitehall II Study cohort (n=8665, 69% men, aged 35-55 at baseline), who had provided information about their reports of back pain between 1985 and 1994. Data about exit from paid employment (health-related and non-health related exit, unemployment and other exit) were collected between 1995 and 2013. Repeated measures logistic regression models were fitted to examine the associations, and adjust for covariates. RESULTS: Recurrent pain was reported by 18% of participants, while 26% reported pain on an occasion and 56% did not report pain. Report of back pain on an occasion was not associated with health-related job exit, whereas recurrent pain was associated with such an exit (OR 1.51; 95% CI 1.15 to 1.99), when compared with those who did not report pain. These associations were somewhat stronger among middle-grade and lower-grade employees, while these associations were not seen among higher-grade employees. Differences in associations by age and psychosocial working conditions were small. CONCLUSIONS: These results highlight the need for early detection of recurrent back pain to prevent exit out of paid employment for health reasons. As the risk varies by occupational grade, this emphasises the importance of identification of high-risk groups and finding ways to address their modifiable risk factors. PMID- 30287682 TI - Catastrophic haemorrhage in military major trauma patients: a retrospective database analysis of haemostatic agents used on the battlefield. AB - OBJECTIVES: Catastrophic haemorrhage is a leading cause of morbidity and mortality in trauma, in both military and civilian settings. There are numerous studies looking at the effectiveness of different haemostatic agents in the laboratory but few in a clinical setting. This study analyses the use of haemostatic dressings used in patients injured on the battlefield and their association with survival. METHOD: A retrospective database review was undertaken using the UK Joint Theatre Trauma Registry from 2003 to 2014, during combat operations in Iraq and Afghanistan. Data included patient demographics, the use of haemostatic dressings, New Injury Severity Score (NISS) and patient outcome. RESULTS: Of 3792 cases, a haemostatic dressing was applied in 317 (either Celox, Hemcon or Quickclot). When comparing patients who had a haemostatic dressing applied versus no haemostatic agent, there was a 7% improvement in survival. Celox was the only individual haemostatic dressing that was associated with a statistically significant improvement in survival, which was most apparent in the more severely injured (NISS 36-75). CONCLUSION: We have shown an association between use of haemostatic agents and improved survival, mostly in those with more severe injuries, which is particularly evident in those administered Celox. This supports the continued use of haemostatic agents as part of initial haemorrhage control for patients injured in conflict and suggests that civilian organisations that may need to deal with patients with similar injury patterns should consider their use and implementation. PMID- 30287683 TI - A comparison of CT lung voxel density analysis in a blast and non blast injured casualty. AB - INTRODUCTION: Primary blast lung injury (PBLI) is a prominent feature in casualties following exposure to blast. PBLI carries high morbidity and mortality, but remains difficult to diagnose and quantify. Radiographic diagnosis of PBLI was historically made with the aid of plain radiographs; more recently, qualitative review of CT images has assisted diagnosis. METHODS: We report a novel way of measuring post-traumatic acute lung injury using CT lung density analysis in two casualties. One casualty presented following blast exposure with confirmed blast lung injury and the other presented following extremity injury without blast exposure. Three-dimensional lung maps of each casualty were produced from their original trauma CT scan. Analysis of the lung maps allowed quantitative radiological comparison exposing areas of reduced aeration of the patient's lungs. RESULTS: 45% of the blast-exposed lungs were non-aerated compared with 10% in the non-blast-exposed lungs. DISCUSSION: In these example cases quantitative CT lung density analysis allowed blast-injured lungs to be distinguished from non-blast-exposed lungs. PMID- 30287681 TI - tRNA epitranscriptomics and biased codon are linked to proteome expression in Plasmodium falciparum. AB - Among components of the translational machinery, ribonucleoside modifications on tRNAs are emerging as critical regulators of cell physiology and stress response. Here, we demonstrate highly coordinated behavior of the repertoire of tRNA modifications of Plasmodium falciparum throughout the intra-erythrocytic developmental cycle (IDC). We observed both a synchronized increase in 22 of 28 modifications from ring to trophozoite stage, consistent with tRNA maturation during translational up-regulation, and asynchronous changes in six modifications. Quantitative analysis of ~2,100 proteins across the IDC revealed that up- and down-regulated proteins in late but not early stages have a marked codon bias that directly correlates with parallel changes in tRNA modifications and enhanced translational efficiency. We thus propose a model in which tRNA modifications modulate the abundance of stage-specific proteins by enhancing translation efficiency of codon-biased transcripts for critical genes. These findings reveal novel epitranscriptomic and translational control mechanisms in the development and pathogenesis of Plasmodium parasites. PMID- 30287684 TI - The atlastin membrane anchor forms an intramembrane hairpin that does not span the phospholipid bilayer. AB - The endoplasmic reticulum (ER) is composed of flattened sheets and interconnected tubules that extend throughout the cytosol and makes physical contact with all other cytoplasmic organelles. This cytoplasmic distribution requires continuous remodeling. These discrete ER morphologies require specialized proteins that drive and maintain membrane curvature. The GTPase atlastin is required for homotypic fusion of ER tubules. All atlastin homologs possess a conserved domain architecture consisting of a GTPase domain, a three-helix bundle middle domain, a hydrophobic membrane anchor, and a C-terminal cytosolic tail. Here, we examined several Drosophila-human atlastin chimeras to identify functional domains of human atlastin-1 in vitro Although all chimeras could hydrolyze GTP, only chimeras containing the human C-terminal tail, hydrophobic segments, or both could fuse membranes in vitro We also determined that co-reconstitution of atlastin with reticulon does not influence GTPase activity or membrane fusion. Finally, we found that both human and Drosophila atlastin hydrophobic membrane anchors do not span the membrane, but rather form two intramembrane hairpin loops. The topology of these hairpins remains static during membrane fusion and does not appear to play an active role in lipid mixing. PMID- 30287685 TI - Simulations of the regulatory ACT domain of human phenylalanine hydroxylase unveil its mechanism of phenylalanine binding. AB - Phenylalanine hydroxylase (PAH) regulates phenylalanine (Phe) levels in mammals to prevent neurotoxicity resulting from high Phe concentrations as observed in genetic disorders leading to hyperphenylalaninemia and phenylketonuria. PAH senses elevated Phe concentrations by transient allosteric Phe binding to a protein-protein interface between ACT domains of different subunits in a PAH tetramer. This interface is present in an activated PAH tetramer (A-PAH) and absent in a resting-state PAH tetramer (RS-PAH). To investigate this allosteric sensing mechanism, here we used the GROMACS molecular dynamics simulation suite on the Folding@home computing platform to perform extensive molecular simulations and Markov state model (MSM) analysis of Phe binding to ACT domain dimers. These simulations strongly implicated a conformational selection mechanism for Phe association with ACT domain dimers and revealed protein motions that act as a gating mechanism for Phe binding. The MSMs also illuminate a highly mobile hairpin loop, consistent with experimental findings also presented here that the PAH variant L72W does not shift the PAH structural equilibrium toward the activated state. Finally, simulations of ACT domain monomers are presented, in which spontaneous transitions between resting-state and activated conformations are observed, also consistent with a mechanism of conformational selection. These mechanistic details provide detailed insight into the regulation of PAH activation and provide testable hypotheses for the development of new allosteric effectors to correct structural and functional defects in PAH. PMID- 30287687 TI - The C terminus of the bacterial multidrug transporter EmrE couples drug binding to proton release. AB - Ion-coupled transporters must regulate access of ions and substrates into and out of the binding site to actively transport substrates and minimize dissipative leak of ions. Within the single-site alternating access model, competitive substrate binding forms the foundation of ion-coupled antiport. Strict competition between substrates leads to stoichiometric antiport without slippage. However, recent NMR studies of the bacterial multidrug transporter EmrE have demonstrated that this multidrug transporter can simultaneously bind drug and proton, which will affect the transport stoichiometry and efficiency of coupled antiport. Here we investigated the nature of substrate competition in EmrE using multiple methods to measure proton release upon the addition of saturating concentrations of drug as a function of pH. The resulting proton-release profile confirmed simultaneous binding of drug and proton, but suggested that a residue outside EmrE's Glu-14 binding site may release protons upon drug binding. Using NMR-monitored pH titrations, we trace this drug-induced deprotonation event to His-110, EmrE's C-terminal residue. Further NMR experiments disclosed that the C terminal tail is strongly coupled to EmrE's drug-binding domain. Consideration of our results alongside those from previous studies of EmrE suggests that this conserved tail participates in secondary gating of EmrE-mediated proton-drug transport, occluding the binding pocket of fully protonated EmrE in the absence of drug to prevent dissipative proton transport. PMID- 30287686 TI - Oligomerization of the HECT ubiquitin ligase NEDD4-2/NEDD4L is essential for polyubiquitin chain assembly. AB - The NEDD4-2 (neural precursor cell-expressed developmentally down-regulated 4-2) HECT ligase catalyzes polyubiquitin chain assembly by an ordered two-step mechanism requiring two functionally distinct E2~ubiquitin-binding sites, analogous to the trimeric E6AP/UBE3A HECT ligase. This conserved catalytic mechanism suggests that NEDD4-2, and presumably all HECT ligases, requires oligomerization to catalyze polyubiquitin chain assembly. To explore this hypothesis, we examined the catalytic mechanism of NEDD4-2 through the use of biochemically defined kinetic assays examining rates of 125I-labeled polyubiquitin chain assembly and biophysical techniques. The results from gel filtration chromatography and dynamic light-scattering analyses demonstrate for the first time that active NEDD4-2 is a trimer. Homology modeling to E6AP revealed that the predicted intersubunit interface has an absolutely conserved Phe-823, substitution of which destabilized the trimer and resulted in a >=104 fold decrease in k cat for polyubiquitin chain assembly. The small-molecule Phe 823 mimic, N-acetylphenylalanyl-amide, acted as a noncompetitive inhibitor (Ki = 8 +/- 1.2 mm) of polyubiquitin chain elongation by destabilizing the active trimer, suggesting a mechanism for therapeutically targeting HECT ligases. Additional kinetic experiments indicated that monomeric NEDD4-2 catalyzes only HECT~ubiquitin thioester formation and monoubiquitination, whereas polyubiquitin chain assembly requires NEDD4-2 oligomerization. These results provide evidence that the previously identified sites 1 and 2 of NEDD4-2 function in trans to support chain elongation, explicating the requirement for oligomerization. Finally, we identified a conserved catalytic ensemble comprising Glu-646 and Arg 604 that supports HECT-ubiquitin thioester exchange and isopeptide bond formation at the active-site Cys-922 of NEDD4-2. PMID- 30287689 TI - ER stress signaling has an activating transcription factor 6alpha (ATF6) dependent "off-switch". AB - In response to an accumulation of unfolded proteins in the endoplasmic reticulum (ER) lumen, three ER transmembrane signaling proteins, inositol-requiring enzyme 1 (IRE1), PRKR-like ER kinase (PERK), and activating transcription factor 6alpha (ATF6alpha), are activated. These proteins initiate a signaling and transcriptional network termed the unfolded protein response (UPR), which re establishes cellular proteostasis. When this restoration fails, however, cells undergo apoptosis. To investigate cross-talk between these different UPR enzymes, here we developed a high-content live cell screening platform to image fluorescent UPR-reporter cell lines derived from human SH-SY5Y neuroblastoma cells in which different ER stress signaling proteins were silenced through lentivirus-delivered shRNA constructs. We observed that loss of ATF6 expression results in uncontrolled IRE1-reporter activity and increases X box-binding protein 1 (XBP1) splicing. Transient increases in both IRE1 mRNA and IRE1 protein levels were observed in response to ER stress, suggesting that IRE1 up-regulation is a general feature of ER stress signaling and was further increased in cells lacking ATF6 expression. Moreover, overexpression of the transcriptionally active N-terminal domain of ATF6 reversed the increases in IRE1 levels. Furthermore, inhibition of IRE1 kinase activity or of downstream JNK activity prevented an increase in IRE1 levels during ER stress, suggesting that IRE1 transcription is regulated through a positive feed-forward loop. Collectively, our results indicate that from the moment of activation, IRE1 signaling during ER stress has an ATF6-dependent "off-switch."

AB - The life cycle of malaria parasites in both their mammalian host and mosquito vector consists of multiple developmental stages that ensure proper replication and progeny survival. The transition between these stages is fueled by nutrients scavenged from the host and fed into specialized metabolic pathways of the parasite. One such pathway is used by Plasmodium falciparum, which causes the most severe form of human malaria, to synthesize its major phospholipids, phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine. Much is known about the enzymes involved in the synthesis of these phospholipids, and recent advances in genetic engineering, single-cell RNA-Seq analyses, and drug screening have provided new perspectives on the importance of some of these enzymes in parasite development and sexual differentiation and have identified targets for the development of new antimalarial drugs. This Minireview focuses on two phospholipid biosynthesis enzymes of P. falciparum that catalyze phosphoethanolamine transmethylation (PfPMT) and phosphatidylserine decarboxylation (PfPSD) during the blood stages of the parasite. We also discuss our current understanding of the biochemical, structural, and biological functions of these enzymes and highlight efforts to use them as antimalarial drug targets. PMID- 30287691 TI - [The Laterality of Parietal Association Areas: Hemispatial Neglect, Body Images and Body Schema]. AB - This paper discusses the laterality of parietal association areas, focusing on hemispatial neglect and body representation. Extra-personal spatial neglect can be severe and is frequently observed following right parietal lesions; personal neglect is also common with right parietal lesions. According to the frame of awareness and perception, I speculate that the awareness of space is related to hemispatial neglect of extra-personal space, and awareness of body is related to personal neglect. Both clinical symptoms are common with right parietal lesions. On the other hand, I speculate that the perception of body is related to autotopagnosia, which could be associated with left parietal lesions. PMID- 30287692 TI - [Left and Right Hemispheric Contribution to Social Cognition]. AB - Can we find hemispheric differences in the neural systems of social cognition? Social cognition is supported by a number of cognitive systems. Emotion plays an important role in understanding others and in controlling self-action. Theory of mind, the ability to infer the mental state of others, consists of subsystems such as empathy, mentalization, and perspective taking. Key brain structures for these cognitive processes are the medial prefrontal cortex, regions around the superior temporal sulcus, and the temporo-parietal junction. Most studies show right hemisphere dominance in emotional and social processes. With regard to the theory of mind, empathy is dominantly supported by the right hemisphere. However, some findings suggest the involvement of both hemispheres in mentalization and perspective talking. Social cognition is a complex process and should be considered as the consequence of inter-hemispheric processing involving several structures, although it is mainly right-hemisphere dominant. PMID- 30287690 TI - Scrambling of natural and fluorescently tagged phosphatidylinositol by reconstituted G protein-coupled receptor and TMEM16 scramblases. AB - Members of the G protein-coupled receptor and TMEM16 (transmembrane protein 16) protein families are phospholipid scramblases that facilitate rapid, bidirectional movement of phospholipids across a membrane bilayer in an ATP independent manner. On reconstitution into large unilamellar vesicles, these proteins scramble more than 10,000 lipids/protein/s as measured with co reconstituted fluorescent nitrobenzoxadiazole (NBD)-labeled phospholipids. Although NBD-labeled phospholipids are ubiquitously used as reporters of scramblase activity, it remains unclear whether the NBD modification influences the quantitative outcomes of the scramblase assay. We now report a refined biochemical approach for measuring the activity of scramblase proteins with radiolabeled natural phosphatidylinositol ([3H]PI) and exploiting the hydrolytic activity of bacterial PI-specific phospholipase C (PI-PLC) to detect the transbilayer movement of PI. PI-PLC rapidly hydrolyzed 50% of [3H]PI in large symmetric, unilamellar liposomes, corresponding to the lipid pool in the outer leaflet. On reconstitution of a crude preparation of yeast endoplasmic reticulum scramblase, purified bovine opsin, or purified Nectria haematococca TMEM16, the extent of [3H]PI hydrolysis increased, indicating that [3H]PI from the inner leaflet had been scrambled to the outer leaflet. Using transphosphatidylation, we synthesized acyl-NBD-PI and used it to compare our PI-PLC-based assay with conventional fluorescence-based methods. Our results revealed quantitative differences between the two assays that we attribute to the specific features of the assays themselves rather than to the nature of the phospholipid. In summary, we have developed an assay that measures scrambling of a chemically unmodified phospholipid by a reconstituted scramblase.

AB - The left inferior frontal gyrus, a part of the left frontal association cortex, is known to be involved in syntactic processing. Recently, we identified three syntax-related networks, which included each of the three regions of the left frontal association cortex. Moreover, patients with agrammatic comprehension caused by damage to the left association cortex showed changes in functional connectivity in the entire syntax-related network. These findings suggest that the left frontal association cortex is at the core of syntax-related networks. PMID- 30287694 TI - [The Current Status of Corpus Callosotomy for Epilepsies]. AB - Surgery is considered a therapeutic option for drug-resistant epilepsies. As a first step, the epileptic focus is carefully examined using extra- and intra cranial EEG and various neurodiagnostic imaging techniques, such as magnetic resonance imaging, intra-ictal single photon emission computed tomography, magnetoencephalography, and functional near-infrared spectoroscopy. Only when the epileptogenic focus can not be identified, callosotomy is considered as a palliative surgical method. It is indicated especially in cases with drop attacks, which severely exacerbate the patient's quality of life. Almost complete drop attack remission can be expected after callosotomy. Each year, about 40 cases of callosotomy are registered in Japan. Postsurgical split-brain syndromes are observed for several months and gradually disappear, especially in young children. PMID- 30287695 TI - [Right-versus Left-handedness in Behavioral and Cognitive Neuroscience]. AB - Globally, approximately 90% of individuals are right-handed, while the remaining 10% are left-handed. Handedness is associated with functional lateralization of cerebral dominance, and may also be associated with various types of psychological characteristics. Unfortunately, neuromyths of left handedness have become deeply embedded in public consciousness due to misleading studies. In neuroscience research, it is common for left-handed individuals to be excluded from study cohorts in an attempt to increase data uniformity. Left-handed participants represent a substantial portion of the population and their inclusion of left-handed participants can be informative in studies of cerebral asymmetry. We should aim to construct a society that allows people with diverse characteristics, such as left-handed individuals live without discomfort or stress. PMID- 30287696 TI - [Superficial Siderosis]. AB - Superficial siderosis (SS) is a rare, neurodegenerative disease that results from toxic accumulation of hemosiderin on the surface of the brain and spinal cord. The Japanese guidelines for diagnosis and classification of SS have been classified into three categories, according to the distribution of iron deposition and the clinical symptoms, as follows: "classical" type, "localized" type and "atypical" type. In "classical" type SS, patients typically present with slowly progressive and irreversible cerebellar ataxia, sensorineural hearing loss, and/or myelopathy, due to involvement of the acoustic nerve, cerebellum, and spinal cord. T2-weighted imaging (WI) or T2* WI demonstrates characteristic linear low intensity signals along the surface of the brain and spinal cord. However, the natural history and clinical evolution of SS are poorly understood. Furthermore identification and resolution of the bleeding source do not elicit prompt clinical recovery or radiological reversal of SS in most cases. Pharmacological treatments for SS primarily include strategies that produce iron chelation. For example, deferiprone is the only treatment that crosses the blood brain barrier and binds hemosiderin in the central nervous system. PMID- 30287697 TI - [A Case of Neuromyelitis Optica Spectrum Disease with Hypoglycorrhachia]. AB - A 75-year-old Japanese woman developed myelitis 3years prior to her admission. She was diagnosed with HTLV-1-related myelitis and had taken prednisolone. Her myelitis relapsed several times, and serum aquaporin-4 was positive in an ELISA. She developed a sudden headache, consciousness disturbance, dysarthria, and left limb paralysis, and was admitted to our hospital. The CSF analysis revealed pleocytosis dominated by morphonuclear cells and hypoglycorrhachia. Magnetic resonance imaging revealed abnormalities in the corpus callosum, bilateral thalamus, and corticospinal tracts. We initially suspected a relapse of neuromyelitis optica spectrum disorder (NMOSD) and infection. We treated the patient with methylprednisolone pulse and antibacterial and antiviral treatment, which were not effective. Plasmapheresis was performed five times, and she gradually improved. Immunosuppressive treatment was added. It is rare for NMOSD to cause hypoglycorrhachia. This case suggests that infection may trigger an autoimmune response in NMOSD.

AB - Mathematical biology involves the use of mathematical models derived from biological data to predict the course or outcome of a biological event. In oncology, mathematics plays a vital role in determining the tumor behavior and the optimal treatment strategy including the right combination of treatment modality to be used, and the timing and duration of the treatment. The major limiting factor in mathematical oncology is the inability to obtain accurate biological data to formulate appropriate mathematical models.1 Development of molecular biology has enabled us to overcome these limitations. PMID- 30287700 TI - Oral Lesions found in a Dental School in Southern Brazil. AB - OBJECTIVE: This study aimed to perform an epidemiological survey of the cases of oral lesions diagnosed in a Brazilian dental school. MATERIALS AND METHODS: An epidemiological survey was carried out at the Faculty of Dentistry of the University of Passo Fundo (FOUPF), Rio Grande do Sul, Brazil, between March 2015 and June 2017, characterizing the patients in terms of gender, age, and ethnicity. A total of 3,200 records were evaluated, from which 716 presented information on oral lesions diagnosed and treated at the clinics of the FOUPF. The data were evaluated by descriptive statistics of frequency. RESULTS: The most frequent change was the coated tongue (13.83%). The majority of the patients were female (56%), white (31.57%), in the sixth decade of life (21.65%). Regarding the classification of lesions, the most frequent group was developmental changes (25%). CONCLUSION: It is considered that the sample studied presented a significant index of oral lesions and normality changes, considering that 716 (22.38%) patients studied showed some type of change in the oral cavity. CLINICAL SIGNIFICANCE: The sample studied presents peculiar characteristics regarding the number of oral lesions/conditions diagnosed. It is also considered that Schools of Dentistry are valuable environments for carrying out epidemiological surveys in stomatology, providing the diagnostic exercise, as long as the students are stimulated for this purpose. PMID- 30287701 TI - Effectiveness of Mentha piperita Leaf Extracts against Oral Pathogens: An in vitro Study. AB - AIM: The study aims to assess the Mentha piperita leaf extract's effectiveness against oral pathogens. MATERIALS AND METHODS: The leaf extract of M. piperita was prepared using cold water method. The three microbial strains, i.e., Streptococcus mutans, Aggregatibacter actinomycetem-comitans, and Candida albicans were used as microbiological materials. Chlorhexidine 0.2% was used as positive control. The digital caliper was used to measure the zone of inhibition to know the antimicrobial activity at 24 and 48 hours. To compare the activity within and between the different microbial strains, one-way analysis of variance (ANOVA) was used. To analyze the data, Statistical Package for the Social Sciences (SPSS) software version of 21.0 was used. The p-value <=0.05 was considered as statistically significant. RESULTS: Maximum inhibition zone was seen in both M. piperita extracts and 0.2% chlorhexidine with S. mutans at 24 and 48 hours, followed by A. actinomycetemcomitans, and C. albi-cans respectively. The statistical analysis ANOVA reveals the statistically significant association of M. piperita extracts with p-value <0.001. The comparison with 0.2% chlorhexidine at 24 hours showed a p-value of <0.04 and at 48 hours, it showed a p-value <0.001, which was statistically significant. CONCLUSION: The present study concluded that M. piperita showed antimicrobial activity against the oral microorganisms which are causing major less or more severe oral diseases and it can be administered as an alternative medicine for the conventional treatment. CLINICAL SIGNIFICANCE: The study results serve as a guide in selecting and providing information about the efficacy of M. piperita extracts to the dental professionals. The discovery of a potential herbal medication would be a great development in the field of antimicrobial therapies. PMID- 30287702 TI - In vitro Analysis of Shear Bond Strength and Adhesive Remnant Index of Stainless Steel Brackets with Different Adhesive Systems to Enamel. AB - AIM: This study aimed at evaluating and comparing the bond strength of stainless steel brackets bonded with multiple orthodontic adhesives. MATERIALS AND METHODS: About 60 premolars extracted to create space during orthodontic treatment were included in the present study. Premolar stainless steel brackets of size 0.022" slot with the surface area of bracket base of 11.15 mm2 were used. The premolars were divided randomly into three groups of 20 in each. Group I: Conventional Acid Etching (Transbond XT); group II: Seventh-generation adhesive materials (Xeno V); and group III: Flowable composite (Filtek Z350 XT). Calculation of Adhesive Remnant Index (ARI) was done and shear bond strength was assessed. The probability level of 0.05 was considered as clinically significant. RESULTS: The shear bond strength was highest in group II (17.46 +/- 1.36), which was followed by group I (15.33 +/- 2.78) and the least was shown by group III (13.96 +/- 1.44). A statistically significant difference was found between group I vs II, group II vs III, and group III vs II. Utmost prevalence of about 35% was found in Transbond XT with an ARI score of 3 (followed by all adhesive left on the tooth), Filtek Z350 XT with 20%, and the least was found with Xeno V, about 5%. The probability was found to be p = 0.025 among different groups, which is statistically significant according to chi-square test. CONCLUSION: The study concluded that the adhesive materials of the seventh generation showed higher shear bond strength than that of the flowable composite and conventional acid etching. The ARI indicated that a minimum amount of the residual adhesive was found on the surface of the enamel after debonding. CLINICAL SIGNIFICANCE: This study helps orthodontists to select appropriate adhesive and orthodontic brackets for the benefit of the patient and to distinguish the distribution of stress homogeneously within the layer of cement while loading and subsequently minimizing the damage to the enamel during the debonding of orthodontic brackets. PMID- 30287703 TI - Influence of Restoration Height and Masticatory Load Orientation on Ceramic Endocrowns. AB - AIM: Endocrown restorations are an alternative to restore end-odontically treated teeth. Due to the fact that in the literature it is recommended a remnant of 1.5 mm, different heights of endocrown were elaborated and analyzed, obtaining possible faults and their location. This study aimed to evaluate the mechanism of stress distribution in the tooth/restoration set, varying two factors: "restoration height"-three levels, and load application-two levels (oblique or axial), totaling six groups. MATERIALS AND METHODS: For finite element analysis (FEA), a maxillary premolar was modeled with an endodontic treatment. Then, this template was triplicated and each copy received an endocrown restoration of different heights: G6 (4.5 mm), G7 (5.5 mm), and G8 (6.5 mm). The models were exported in STEP format to analysis software (ANSYS 17.2, ANSYS Inc.). During preprocessing, the solids were considered isotropic, linearly elastic, and homogeneous. Initially, a load (300 N) was axially applied in the central fossa region. For a second evaluation, an oblique load (300 N) was applied on the grinding slope of functional cusp. System fixation occurred at the base of poly urethane cylinder. Results were evaluated through maximum principal stress (MPS). RESULTS: For axial load, lower stress values were generated in all groups. For oblique load, G8 showed a higher stress concentration in the cement layer and root dentin. CONCLUSION: When an endocrown restoration is performed, there is a tendency of failure in the cement line and in the root directly proportional to its size. However, regardless of the size of the element to be reconstituted, the axial direction of the masticatory loads tends to decrease stress concentration. CLINICAL SIGNIFICANCE: When performing an endocrown restoration, care must be taken with its high regardless the tooth remnant high, altering even the anatomical angulations of the occlusal face, when necessary, to avoid stress concentration in thick areas. PMID- 30287704 TI - Control of Anxiety in Pediatric Patients using "Tell Show Do" Method and Audiovisual Distraction. AB - INTRODUCTION: Visiting a dentist can easily evoke strong fear reactions and acute anxiety in children. It is one of the most basic reasons for avoidance and neglect of dental care. It may obstruct delivery of dental care, as the child may be unwilling to accept the treatment being provided by the dentist. AIM: To evaluate and compare reduction in anxiety level in patients undergoing dental treatment at first dental visit. TECHNIQUE: The study was conducted on 400 patients coming to the Department of Pedodontics and Preventive Dentistry, Guru Teg Bahadur Hospital, University College of Medical Sciences, New Delhi, for their first dental visit. Anxiety was recorded using facial image scale (FIS), Venham's picture test (VPT), blood pressure, pulse rate (PR), and oxygen saturation (SpO2) at different stages of the visit. Patients coming for the first dental visit were subjected to restorative treatment under Tell show do (TSD) method and audiovisual distraction (AVD). The data collected were tabulated and subjected to statistical analysis. CONCLUSION: The AVD was found to be more capable in reducing anxiety than TSD. Combination of TSD and AVD had an additive effect in reduction of anxiety level and it proved to be more beneficiary. CLINICAL SIGNIFICANCE: If a child's behavior in the dental office cannot be managed, then it is difficult to hold out any dental treatment that is needed. Bringing positivity in the child's behavior would not only increase efficiency of work but would also make the experience for child undergoing treatment more pleasant. PMID- 30287705 TI - Study to evaluate the Efficacy of Resin-modified Glass lonomer Cement Liner as a Direct Pulp Capping Material. AB - AIM: The aim of the present in vivo study was to compare efficacy of light-cured resin-modified glass ionomer liner, VitrebondTM (3M ESPE) with Dycal(r) (Dentsply) on the healing of pulpal tissue in the event of a direct iatrogenic pulpal exposure. MATERIALS AND METHODS: Experimental group consisted of VitrebondTM (3M ESPE) resin-modified glass ionomer liner, and VitremerTM (3M ESPE) resin-modified glass ionomer cement (GIC) in comparison with the control group of Dycal(r) (Dentsply) as liner and Poly F(r) (Dentsply) dental cement. Class V cavities were prepared in 32 sound premolars that were scheduled for orthodontic extraction, and the exposures were capped according to groups. Five teeth from each group were extracted under local anesthesia after an interval of 24 hours, 35 and 60 days, and evaluated for inflammation, fibrotic changes, formation of reparative dentin and bacterial examination. RESULTS: The present study did not show any statistically significant difference between two groups in terms of inflammation, fibrosis, reparative dentin formation, and bacterial examination. CONCLUSION: This study shows that VitrebondTM (3M ESPE) light-cured resin-modified glass ionomer liner can be used as an alternative to calcium hydroxide as a direct pulp capping material. CLINICAL SIGNIFICANCE: Light-cured resin-modified glass ionomer liner can be an alternative for the calcium hydroxide-based liner for capping iatrogenic pulp exposures. PMID- 30287706 TI - Eruption of Impacted Teeth in Cleft Lip and Palate Patients following Alveolar Bone Graft. AB - INTRODUCTION: This study aimed to assess the eruption of impacted teeth in cleft lip and/or palate (CLP) after alveolar bone graft. MATERIALS AND METHODS: Research was carried out through a cross-sectional study at the Craniofacial Rehabilitation Center of the University General Hospital of the University of Cuiaba, Mato Grosso, Brazil. Variables related to cleft, cleft side, gender, age, laterality of cleft, impacted teeth, and orthodontic traction were analyzed. RESULTS: Forty-two patients treated at the institution from 2004 to 2011 had their charts retrospectively reviewed. They were 54.7% male and 45.2% female. The group aged 9 to 11 years was most affected, representing 59.5% of cases. A unilateral cleft was the most prevalent craniofacial anomaly (85.7%). A total of 57 impacted teeth were observed. Maxillary canines were the most commonly impacted teeth (97.6%) and the most frequently identified in patients with a transforamen incisor cleft (TIC) (76.3%). Orthodontic traction was required for both impacted maxillary canines and impacted lateral incisors (64.3 and 35.7% respectively). The orthodontic traction was required only in patients with a TIC (p = 0.0101). CONCLUSION: The canine teeth were the most commonly impacted teeth, found mainly in patients with a TIC. After placement of the alveolar bone graft in patients with a preforamen incisor cleft (PIC), all impacted teeth erupted spontaneously. CLINICAL SIGNIFICANCE: An impacted tooth can have negative consequences on a patient's quality of life. Thus, a survey evaluating the incidence and prognosis of impacted teeth after an alveolar bone graft for CLP was important. PMID- 30287707 TI - Comparative Study of Micronuclei Count in Patients with Different Tobacco-related Habits using Exfoliated Buccal Epithelial Cells: A Tool for Assessment of Genotoxicity. AB - AIM: To study and compare the genotoxic effects of tobacco using micronuclei count in individuals with different tobacco-related habits. MATERIALS AND METHODS: A cross-sectional study was done comprising 200 individuals, divided into four groups. Group I: 50 subjects with history of tobacco chewing, group II: 50 subjects with a history of smoking tobacco, group III: 50 subjects with a history of both tobacco chewing and smoking, and group IV: 50 subjects without any habits as controls (age-matched). The study groups were individually further divided into three subgroups which comprised of subjects with history of substance abuse for less than 5, 5 to 10, and greater than 10 years. Exfoliated cells from the buccal mucosa of the subjects were collected and stained using Giemsa stain. A total of 1,000 cells were examined for each case and micronuclei frequency was scored according to the guidelines given by Tolbert et al. Results: The mean number of micronuclei count was 18.28 +/- 10.0 in group I (smokeless tobacco users), 11.38 +/- 6.3 in group II (subjects with history of tobacco smoking), 22.44 +/- 9.8 in group III (subjects with history of using both smokeless and smokable form of tobacco), and 4.86 +/- 2.4 in the control group. The statistical difference was found to be highly significant (p < 0.001). Similarly, based on the duration, highly significant difference was notable in the mean number of micronuclei in subjects who had a history of substance abuse for more than 10 years. CONCLUSION: A significantly higher micronucleus frequency was found in smokeless tobacco users than in smokers and controls. Micronuclei assay in the exfoliated buccal cells is a useful and minimally invasive method for monitoring early genotoxic damage. CLINICAL SIGNIFICANCE: Micronuclei assay can be used to detect genotoxic damage at the earliest and, if intervened at this point, may prevent frank malignancy, morbidity, and mortality. PMID- 30287708 TI - Comparative Evaluation of Shear Bond Strength and Microleakage of Two Self adhering Composite Resins: An in vitro Study. AB - INTRODUCTION: A good dental cement used as repair material should possess chemical binding, easy handling characteristics, minimal marginal breakdown and minimal polymerization shrinkage, high resistance to wear, high cohesive strength, and good color stability. This study was undertaken to compare the in vitro microleakage and shear bond strength among the newly introduced Prime fill flow and Dyad flow. AIM: The aim of this study was to determine the effect on shear bond strength and microleakage of two self-adhesive composite resin. MATERIALS AND METHODS: Selected specimens were collected and stored in deionized water with an antibactericidal agent, 0.2% sodium azide, until ready to be used and were randomly divided into two groups: group I: Dyad flow and group II: Prime fill flow; specimens were sheared with a universal testing machine, and the results were calculated in megapascal, specimens were sectioned in a mesiodistal direction at four different locations, and analyzed for leakage (dye penetration) using a stereomicroscope. RESULTS: The results of the present study showed that acceptable values for Prime fill flow seemed to have least microleakage and high bond strength as compared with Dyad flow. CONCLUSION: Here, it can be concluded that there was significant difference in the in vitro microleakage and shear bond strength among the Prime fill flow and Dyad flow. CLINICAL SIGNIFICANCE: Self etch adhesives when compared with total-etch systems have the advantage of reducing the application time and the number of steps in pediatric dentistry. Patients' age and cooperation are not always ideal; the treatment outcome is greatly influenced by the patients' behavior. It is therefore imperative to recede the application time of some materials mostly in pediatric dentistry. PMID- 30287709 TI - Evaluation of Influence of Widening Apical Preparation of Root Canals on Efficiency of Ethylenediaminetetraacetic Acid Agitation Protocols: Study by Scanning Electron Microscopy. AB - AIM: The purpose of this study was to evaluate the influence of widening the apical root canal preparation (RCP) on the efficiency of different ethylenediaminetetraacetic acid (EDTA) agitation protocols on smear layer removal: EDTA; EDTA + Easy Clean in rotary movement (ECROT); EDTA + Easy Clean in reciprocating movement (ECREC); and EDTA + Passive ultrasonic irrigation (PUI). MATERIALS AND METHODS: A total of 80 mandibular premolars had their crowns sectioned and then were divided into two groups according to widening: size 25 or 40, 0.08 taper. Sequentially they were once again allocated to subgroups according to the agitation protocol performing eight experimental groups (n = 10). Ten additional teeth were prepared for controls (C+/C-). The specimens were then submitted to the cleaning protocols and thereafter cleaved and microphotographed by variable pressure scanning electron microscopy (SEM) at previously determined points along their root thirds (750*). Scores were attributed to the images, and data were analyzed by the Kruskal-Wallis, Student Newman-Keuls and Friedman tests. RESULTS: A higher widening was observed to have a positive influence on cleaning efficiency offering significant differences in global and apical third evaluations (p < 0.05). Relative to the agitation, significant differences were observed mainly in the apical third, with PUI and ECROT providing the best results (p < 0.05); no difference for C+ was observed when higher widening was employed. CONCLUSION: A greater widening of the apical third provided a significant improvement in the action of the agitation/activation protocols. Moreover, the PUI and ECROT activation methods were shown to be superior to the use of EDTA solely, particularly in the apical third. CLINICAL SIGNIFICANCE: The findings of this study reinforce the need for clinical use of additional methods to complement cleaning. Therefore, it is important for professionals to have knowledge and command of these protocols to obtain more satisfactory results. PMID- 30287710 TI - A Retrospective Analysis of Pulp Stones in Patients following Orthodontic Treatment. AB - AIM: The present study aimed to find prevalence of pulp stones in known South Indian orthodontic patients and to find correlation between pulp stones and patients who underwent orthodontic treatment as well as to reveal any differences due to gender, tooth type, and dental arches. MATERIALS AND METHODS: The present retrospective study was carried out among 200 patients who underwent nonextraction orthodontic treatment. Maxillary and mandibular first and second premolar and molar teeth were selected for the purpose of the study using panoramic radiographs. A total of 3200 teeth of 200 patients were studied for the presence of pulp stones. Statistical analysis of the obtained data was carried out using Statistical Package for Social the Sciences (SPSS) version 22.0. Chi square test was applied to find the significant value and p < 0.05 was considered as a significant value. RESULTS: In all, 11.5% of cases reported pulp stones before the commencement of the orthodontic treatment and 15.5% cases after completion of orthodontic treatment. Overall, 4% increase in cases were found which was statistically significant (p < 0.05); 5.1% of total number of teeth were evaluated in both arches before orthodontic treatment and 6.3% of teeth after orthodontic treatment revealed the presence of pulp stones. Maxillary first molar was found to be teeth with maximum number of pulp stones before and after orthodontic treatment. CONCLUSION: The present study reported the prevalence of pulp stones to be increased by 4% in the pre- and posttreat-ment radiographs, which was statistically significant. The study found the presence of pulp stones more in maxillary first molar and it was found to be teeth with maximum number of pulp stones before and after orthodontic treatment. However, further researches with larger samples are advisable. CLINICAL SIGNIFICANCE: Dentists performing endodontic treatment among patients who have undergone orthodontic treatment should be aware about the increased chances of presence of pulp stones and thus to avoid hindrances encountered during extirpating the pulp, they should thoroughly study the radiographs beforehand. PMID- 30287711 TI - In vitro Evaluation and Comparison of Microleakage of Two Restorative Composite Resins in Class II Situations using Confocal Laser Scanning Microscopy. AB - AIM: The placement of composite in teeth is not an easy task and it poses many challenges. Microleakage is one of the factors that affects the success of any composite restoration. It influences the longevity of dental restorations. The present study was aimed to evaluate and compare microleakage of two restorative composites resins in class II cavities using confocal laser scanning microscopy (CLSM). MATERIALS AND METHODS: This was an in vitro study, which included 20 permanent mandibular first molar. On each tooth, 40 class II cavities were prepared with a carbide bur. The teeth were then randomly divided into two groups of 10 each. Group I included teeth in which SonicFill Bulk Fill composite was used. Group II included teeth in which Tetric EvoCeram Bulk Fill composite was used. The microleakage was measured using confocal microscopy at 10* magnification in the fluorescent mode by a scoring system. RESULTS: Estimation was done at cervical and occlusal levels, wherein group I included 10 teeth which were restored with SonicFill Bulk Fill composite and group II included 10 teeth which were restored with Tetric EvoCeram Bulk Fill composite. Microleakage was quantified on scoring basis, which was consecutively based on the dye penetration at different levels. Data thus obtained statistically revealed that microleakage was comparatively more in group II as compared with group I. In addition, it was somewhat similar on both cervical as well as occlusal regions. The difference was significant (p = 0.05). Comparison was also done at cervical and occlusal levels using Wilcoxon signed-rank test, which showed significant levels of differences (p > 0.05). CONCLUSION: There is more microleakage in Tetric EvoCeram Bulk Fill composite as compared with SonicFill Bulk Fill composite. CLINICAL SIGNIFICANCE: No material seems to totally eliminate microleakage in class II situations with gingival margin ended in dentine. However, CLSM is a useful tool in microleakage evaluation that could be used successfully to estimate the severity of microbial penetrations and material of choice as well. PMID- 30287712 TI - Role of E-cadherin in Progression of Oral Squamous Cell Carcinoma: A Retrospective Immunohistochemical Study. AB - AIM: The aim of present study was to assess the role of E-cadherin in oral carcinogenesis by comparing their expressions in normal oral mucosa, oral epithelial dysplasia (OED), and oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS: To elucidate the pattern of E-cadherin expression in oral carcinogenesis, 21 archival cases of formalin-fixed paraffin-embedded sections of OSCC, 21 OED, and 7 normal oral mucosa samples as control were used for the study. RESULTS: We observed reduction/loss of E-cadherin in membranous expression pattern and staining intensity with progression from dysplasia to oral cancer. CONCLUSION: A decrease in staining intensity and loss of E-cadherin membranous expression were noted from dysplasia to carcinoma, suggesting its role as a tumor suppressor gene. CLINICAL SIGNIFICANCE: E-cadherin can be used as a biomarker to assess and evaluate the progression and prognosis of oral dysplastic lesions and OSCC. PMID- 30287713 TI - Wound Healing in Dental Implant Surgery in Patients with or without Antibiotic Prophylaxis. AB - AIM: To assess the association of various clinical parameters and proinflammatory cytokines in the wound-healing process of dental implants with the presence or absence of antibiotic prophylaxis. MATERIALS AND METHODS: The present study included evaluation of early wound-healing process in patients undergoing dental implant placement procedures with and without antibiotic prophylaxis. A total of 50 patients with partial edentulous arch were included in the present study. All the subjects were broadly divided into two study groups depending upon the presence or absence of prophylactic antibiotic therapy, with 25 patients in each group. One group consisted of subjects who were given prophylactic amoxicillin (2 gm), 1 hour before the starting of the surgery, followed by 500 mg 3 times a day for 1 week. Detection of interleukin (IL)-1beta and -8 cytokine levels in the gingival crevicular fluid (GCF)/peri-implant crevicular fluid (PICF) was done immediately after the dental surgery. All the results were compiled and analyzed by Statistical Package for the Social Sciences (SPSS) software version 17.0. RESULTS: A significant increase in the PICF IL-1beta concentration at postoperative follow-up time was observed in the antibiotic group in comparison with the baseline values. A significant increase in the IL-8 concentration postoperatively in comparison with the baseline values in the antibiotic group was also observed. At the time of surgery, the IL-8 concentrations were statistically lower in the antibiotic group in comparison with the other study group. Concentration of amoxicillin, as observed by high-performance liquid chromatography (HPLC), was lower than the minimum detection levels. CONCLUSION: Detection of amoxicillin is not feasible within the GCF samples immediately after dental surgery procedure. CLINICAL SIGNIFICANCE: Clinical usefulness of prophylactic use of amoxicillin is still doubtful. PMID- 30287714 TI - Comparative Evaluation of the Efficacy of Intraligamentary and Supraperiosteal Injections in the Extraction of Maxillary Teeth: A Randomized Controlled Clinical Trial. AB - AIM: The aim of this clinical trial was to compare the efficiency of the intraligamentary (periodontal ligament) injection with supraperiosteal injections in extraction of maxillary teeth, using pain during injection and extraction as the parameters. MATERIALS AND METHODS: Thirty patients indicated for extraction of maxillary molars were randomly allocated into one of the following intervention groups (n = 15): intraligamentary injection and supraperiosteal injection. In both groups, anesthesia was given using a standard volume of 2% lignocaine with adrenaline 1:2,00,000 with a 27G needle. Patients indicated pain during injection and extraction and this was measured using the visual analog scale (VAS). Statistical analysis of the pain scores was done using chi-square test, Levene's test, and Mann-Whitney U test with the alpha error set at p = 0.05. RESULTS: The mean VAS score for pain during injection was higher for the intraligamentary injection group (VAS = 18.67) than for the supraperiosteal infiltration group (VAS = 16), but this was not statistically significant (p > 0.05). The VAS score during extraction was significantly higher for the intraligamentary injection group (VAS = 34.67) than for the infiltration group (VAS = 20) (p < 0.05). CONCLUSION: Periodontal ligament injections may not be optimal, "stand-alone" alternatives to supraperiosteal injections in the exodontia of maxillary teeth. CLINICAL SIGNIFICANCE: Intraligamentary or periodontal injections are useful in extractions on patients with bleeding disorders, as they eliminate the risk of encountering blood vessels during injections as in the case of nerve blocks. The efficacy of intraligamentary injections in extraction of mandibular teeth has been widely studied. This study evaluates the efficacy of this alternate injection technique on maxillary teeth extraction and, if proved successful, can be useful in patients where supraperiosteal injections are contraindicated. PMID- 30287715 TI - A Novel Mobile Health Approach to Early Diagnosis of Oral Cancer. AB - AIM: The incidence of oral cancer is high in India, which can be reduced by early detection. We aimed to empower frontline health care providers (FHP) for early detection and connect specialist to rural population through mHealth. MATERIALS AND METHODS: We provided training to FHPs in examination of oral cavity, use of mobile phone for image capture, and risk factor analysis. The FHPs were selected from different cohorts in resource-constrained settings. The workflow involved screening of high-risk individuals in door-to-door and workplace settings, and capture of images of suspected lesions. Uploaded data were interpreted and recommendation was sent by specialist from a remote location. Their recommendation was intimated to FHPs who arranged for further action. Two more initiatives, one for multiple dental schools and another for private practitioners, were undertaken. RESULTS: During the period from 2010 to 2018, 42,754 subjects have been screened, and 5,406 subjects with potentially malignant disorders have been identified. The prevalence of potentially malignant disorders varied from 0.8 to 62% at different cohorts; 516 biopsies have been performed at remote locations. CONCLUSION: Connecting specialists to rural population was made possible through the use of mobile health. Trained FHP were able to reach out to the population. Electronic data capture facilitated efficient follow-up. The program was very cost-effective with screening completed under $1 per person. CLINICAL SIGNIFICANCE: In view of the high incidence of oral cancer in India, and the resource-constrained settings, mobile health paves the way for better access to specialist care for the rural population. PMID- 30287716 TI - Effect of Water Sorption and Solubility on Color Stability of Bulk-Fill Resin Composite. AB - AIM: The objective of this study is to compare the bulk-fill resin composite to a conventional one, as regards; water sorption, solubility, and their effect on color stability. MATERIALS AND METHODS: This study was conducted using two types of composites: Bulk-fill composite (Filtek Bulk-Fill) and nanohybrid composite for control (Filtek Z250 XT). Specimens were prepared using a ring mold, 10 from each material. Specimens were desiccated, then weighed in a digital balance until a stable mass was acquired. For water sorption test, specimens were immersed in distilled water and placed in a lightproof incubator at 37 +/- 1 degrees C and the mass was measured weekly for 8 weeks. For solubility test, specimens were desiccated again in the desiccator until a stable mass was achieved. A spectropho tometer was used to record the baseline color measurements prior to water immersion and weekly for 8 weeks. RESULTS: Bulk-fill composite showed higher water sorption value and lower water solubility values compared with that of the conventional one. No statistically significant difference was found for water sorption (p = 0.104) or water solubility (p = 0.098) between groups. The mean DeltaE was lower in bulk-fill than conventional composite, and results showed a statistically significant difference (p = 0.009). CONCLUSION: Bulk-fill resin composite yielded better color stability and similar water sorption and solubility values. CLINICAL SIGNIFICANCE: Bulk-fill resin composite can be used in esthetically concerned patients. PMID- 30287717 TI - Comparison of Frictional Resistance in Conventional Brackets with Different Stainless Steel Wires. AB - AIM: The aim of the study was to evaluate and compare static and kinetic friction of round (0.018") and rectangular (0.019 * 0.025") stainless steel (SS) wires of different brands with conventional preadjusted edgewise brackets. MATERIALS AND METHODS: Maxillary canine and two bicuspids of 0.022 * 0.028" slot sized MBT prescription (Gemini, 3M Unitek, Monrovia, California) brackets were chosen. The wires selected were 0.018" SS (3M Unitek); 0.018" Australian wire (AJ Wilcock, UK), and 0.019 * 0.025" SS (3M Unitek). The testing was done on Instron 3382. A total of 30 test combinations with three wires were repeated 10 times. The static and kinetic friction was recorded in Newton. The kinetic friction was also recorded in Newton at 3, 5, 7, and 9 mm of movement. One-way analysis of variance (ANOVA) and descriptive statistics were used for comparing the friction. To test the level of significance, multiple comparisons were used within wire in bracket by using post hoc test. RESULTS: Static friction was found to be greater than kinetic in all wires; 0.018" SS (3M) wire exhibited minimum static and kinetic friction; while 0.019 * 0.025" SS (3M) exhibited maximum static friction. Kinetic friction was similar in both 0.018" AJ Wilcock and 0.019 * 0.025" SS but greater than 0.018" SS (3M). CONCLUSION: Least static and kinetic friction was exhibited by 0.018" SS (3M). Kinetic friction was similar in both 0.018" AJ Wilcock and 0.019 * 0.025" SS. CLINICAL SIGNIFICANCE: The study concluded that 0.018" SS (3M) is better for individual canine retraction than the other wires used in the study because it has the least frictional resistance; 0.019 * 0.025" SS (3M) is a better wire for canine retraction than 0.018" AJ Wilcock as we can have a three dimensional control over tooth movement. When torque control is not a prime requisite, then 0.018" SS (3M) can be used for retraction of incisors instead of 0.018" AJ Wilcock in severely proclined incisor cases. PMID- 30287718 TI - Knowledge, Attitude, and Behavior toward Evidence-based Dentistry among Dental Professionals in Jodhpur Rajasthan, India. AB - INTRODUCTION: Rendering quality care to the patient, dentists needs to update their skills and knowledge with latest diagnostics and treatment modalities. Evidence-based dentistry can provide best-known treatments. AIM: To assess knowledge, attitude, and practice of oral healthcare professionals toward evidence-based dentistry among dental professionals. MATERIALS AND METHODS: A cross-sectional study was conducted for a period of 3 months from April 2017 to June 2017 in Jodhpur city, Rajasthan, India. The data were collected by using closed-ended questionnaires. A total of 240 study subjects participated in the survey, which include dental practitioners and dentists attached to the two private dental colleges in the Jodhpur. Chi-square test was used to determine significant difference among the three groups. RESULTS: Statistically significant difference among the three groups (academicians, practitioners, and academicians into dental practice) was found with regard to awareness of dentists about extracting journals, review publications, and databases relevant in carrying out evidence-based practice (EBP); 72.4% of academician felt lack of personal time was one of the major perceived barriers and about 50.7% of academician believe that learning skills of evidence-based dentistry helps them to utilize evidence based dentistry in daily practice. CONCLUSION: Majority of the oral health practitioners were not aware about the concept of evidence-based dentistry. The regulatory body of dental sciences in India should make some necessary changes in the dental curriculum to include the concept of evidence-based dentistry in detail. CLINICAL SIGNIFICANCE: To improve the clinical expertise of the dental professional, to aid dental professional to reach best decision regarding dental treatment of the patient, to improve patient safety, and to improve the success rate of dental treatments, evidence-based dentistry should be the integral part of everyday dental practice. PMID- 30287719 TI - The Efficiency of Three Irrigating Solutions after Surgical Removal of Impacted Mandibular Third Molars: A Cross-sectional Study. AB - AIM: The present study was conducted to assess the effect of irrigation with three different irrigants, namely normal saline, chlorhexidine, and povidone iodine on pain, alveolar osteitis, swelling, trismus, infection, and food impaction during surgical removal of impacted mandibular third molar. MATERIALS AND METHODS: Forty-eight patients, including 26 males and 22 females, fulfilling criteria for inclusion in this study were divided into three groups: group I where irrigant used was normal saline, group II as chlorhexidine, and group III as povidone iodine group. RESULTS: The pain was significantly more in groups I and III in 24 hours and 7th day as well. Alveolar osteitis was noted in groups III and I, nil in group II. The facial swelling measured in millimeters on 24 hours and on 7th day was significantly higher in 24 hours in groups I and III than in group II. Trismus was significantly more in group I and group III than in group II (with p < 0.01) on 7th day. CONCLUSION: It is concluded that chlorhexidine is effective in reducing pain, alveolar osteitis, swelling, and trismus when used as an irrigant following surgical removal of impacted third molar. CLINICAL SIGNIFICANCE: Chlorhexidine as irrigating solution helps in reducing the postoperative consequences after third molar surgery. Further studies are required using large sample size. PMID- 30287720 TI - Nonsurgical Management and 2-year Follow-up by means of Cone Beam Computed Tomography of an Invasive Cervical Resorption in a Molar. AB - BACKGROUND: Invasive cervical resorption (ICR) is a relatively uncommon form of external tooth resorption, characterized by an invasive nature. It is usually painless and detection of lesions is often made incidentally. Three-dimensional imaging techniques, such as cone beam computed tomography (CBCT), are useful in the diagnosis and management of ICR as the true extent of the defect cannot always be estimated using conventional radiographs. AIM: The aim of this article is to report on the successful treatment of ICR in mandibular first molar by nonsurgical approach and follow-up by means of CBCT. CASE REPORT: An 18-year-old patient was referred with a complaint of unusual radiolucency in the mesial cervical area of tooth #19 with unknown etiology. Cone beam computed tomography was performed to assess the extent of the lesion in three spatial levels and diagnosis of Heithersay class III ICR was made. This case presented with ICR (Heithersay class III) on tooth #19. Nonsurgical root canal treatment and removal of the lesion from the coronal access was performed; the resorptive defect was filled with dual-cure, self-adhesive, resin-modified glass ionomer cement (RMGIC); 6-month follow-up X-ray film showed no changes at the lesion site and tooth was asymptomatic; 1-year follow-up X-ray film showed slight mesial bone loss and a probing depth of 3 mm; finally, 2-year follow-up CBCT images showed no recurrence and no further bone destruction at the lesion site. CONCLUSION: The intraoral radiographs revealed the resorptive changes in two dimensions; therefore, the actual extent and location of the lesions are not fully understood. On the contrary, CBCT is a very useful tool to achieve a proper diagnosis; it detects the extent of the defect more accurately and hence, improves the treatment outcomes of ICR. CLINICAL SIGNIFICANCE: The ICR is usually seen as a late complication to traumatic injuries of the teeth; it is essential, therefore, that the patients who were exposed to situations that can damage the integrity of periodontal tissue need to have careful periodic recalls and X-ray examinations. PMID- 30287721 TI - Oral Management of Steinert's Disease and Role of Anxiolysis. AB - BACKGROUND: Myotonic dystrophy type I (DM1) is a genetic autosomal dominant disorder; malignant hyperthermia is a possible complication. It may occur following administration of some halogenated general anesthetics, muscle relaxants, or surgical stress. AIM: The purpose of this case report is to evaluate the dental management of patients with Steinert's disease. CASE REPORT: The patient needed dental extraction. A locore-gional paraperiosteal anesthesia was performed using bupiva-caine without vasoconstrictor and sedation with nitrous oxide. The syndesmotomy of the elements 3.1, 4.1, and 4.2 was executed. The elements were dislocated through a straight lever and avulsed with an appropriate clamp. The socket was courted, washing with saline solution, inserting a fibrin sponge, and applying sutures (silk 3-0). CONCLUSION: Dental treatment of the patient with Steinert's dystrophy must be carried out under a hospital environment and the use of local anesthetic without vasoconstrictor and with use of nitrous oxide; anxiolysis is recommended. CLINICAL SIGNIFICANCE: This case report describes the precautions to perform oral surgery in patients with Steinert's disease and emphasizes the role of anxiolysis to avoid episodes of malignant hyperthermia. PMID- 30287722 TI - Korean Red Cross Hospital (1905-1907): Focused on its Establishment, Management and Abolition. AB - The Korean Empire, its state sovereignty threatened by the Empire of Japan, joined the Geneva Conventions in 1903 for the purpose of neutral diplomacy and established the imperial Korean Red Cross Hospital in 1905. This hospital was a result of the effort of the Korean Empire to seek a new medical system based on the Western medicine. However, after the Russo-Japanese War, Japan interfered straightforwardly in the domestic affairs of Korea and eventually abolished the Korean Red Cross Hospital in 1907 to create Daehan Hospital under Japanese colonial rule. With newly-found historical records, this study investigates the whole process of the Korean Red Cross Hospital, which has remained unknown so far, despite its importance. From the very beginning, the Korean Red Cross Hospital was under strong influence of the Empire of Japan. The site for the hospital was chosen by a Japanese army doctor, Junryo Yoshimoto, and the construction was supervised by Rokuro Katsumata, who also later on are involved in the construction of Daehan Hospital. Moreover, all the main positions for medical treatments were held by Japanese practitioners such as Goro Tatami and Kaneko Yano. Nevertheless, the Korean government had to shoulder the all operating costs. The office of the Korean Red Cross was relocated away from the Korean Red Cross Hospital, and the government of the Korean Empire was not willing to burden the expenses of the Hospital. Moreover, the list of employees of the Korean Red Cross and that of the Korean Red Cross Hospital were drawn up separately: the former is left only in Korea and the latter in Japan. These facts suggest that those two institutes were managed dualistically unlike any other nation, implying that this may have been a means to support the Daehan Hospital project. According to the statistics, health care services in the Korean Red Cross Hospital seems to have been carried out successfully. There had been an increase in the number of patients, and the ratio of female patients was relatively high (26.4%). Only Western medications were prescribed and surgical operations with anesthesia were performed routinely. The approach to Western medicine in Korea was changing during that period. The rise and fall of the Korean Red Cross Hospital represent the urgent situation of the Korean Empire as well as the imperialistic methodology of the Empire of Japan to use medicine as a tool for colonization. Although the transition process of medical policy by the Japanese Resident-General of Korea still remains to be fully elucidated, this paper contributes to a better understanding of the history of modern medicine in Korea. PMID- 30287723 TI - Yun Il-sun's Studies in Japan and Medical Research during the Colonial Period. AB - In this article, I looked at the life of Yun Il-sun, a representative medical scientist of modern Korea, and examined the following problems. First, I took note of the position of the Korean people in the academic system of the Japanese colonial empire and restored the life of Yun Il-sun as specifically as possible. Yun was educated among Japanese people from elementary school to university. Although he received the best education at Old System High School and Imperial University and grew to be a prominent medical scientist, he could not overcome his identity as a colonized. Yun Il-sun, who moved from Keijo Imperial University to Severance Union Medical College, involved in activities founding of the Korean Medical Association and the Korean Medical Journal. Second, I the meaning of 'culture' to the intellectuals in the periphery. Old System High School and Imperial University where Yun Il-sun was educated were the hotbed of 'culturalism.' Yun's college days were the heyday of Taisho Democracy, and students were attracted to Marxism, Christian poverty movement, Buddhist cultivation movement and so on. Yun sought to overcome the ideological of young people through the acquisition of 'culture.' The 'culture' emphasized by Yun had an enlightenment characteristic that emphasized education, but it also functioned as a'identity culture of educated elites.' Third, I used the concept of 'colonial academism' and examined the aspects and characteristics of the colonial-periphery academic field, focusing on medicine. Yun Il-sun was a Korean professor at the Keijo Imperial University. He founded an academic society and published an academic journal for Koreans. He attempted to reproduce scholarship by doctoral dissertations. At the same time, several facts show that he was also in the affected area of 'colonial academism': the fact that he was kicked out of the Keijo Imperial University, the fact that the Korean Medical Association and the Korean Medical Journal were banned by Governor General, the fact that his students asked for doctoral degrees from Kyoto Imperial University where he studied. Yun Il-sun crossed the limits of 'colonial academism' and acted as the agent of empire. This was made possible by the characteristics of the academic discipline of medicine, the environment of the Severance Union Medical College, and personal traits of superior ability and indifference to politics. I the postcolonial evolution of the 'colonial academism' and 'culturalism.' The mix of continuity and discontinuity from 'colonial academism' and the hybrid of Japanese academism and American academism, the Korean characteristics of 'postcolonial academism.' Yun tried to harmonize the American academism with the Japanese academism and the purity of academism. This effort was revealed as an emphasis on basic medicine and natural sciences. As combined with culturalism and indifference to politics, he was recognized as the symbol of ivory tower and academism. PMID- 30287724 TI - Beyond the Bifurcated Myth: The Medical Migration of Female Korean Nurses to West Germany in the 1970s. AB - This study investigates beyond the bifurcated myth of the medical migration of Korean women to Germany in the 1970s, which is known as the "German dispatchment" myth from the Korean perspective and the "development aid" discourse from that of the Germans, by focusing on the newly-released documents from the German Hospital Federation (Deutsche Krankenhausgesellschaft, DKG). The migration was essentially a transfer of labor from a weak to a strong state, and the disparity of state strength characterized the nature of the recruitment mechanism. Both Korea and Germany have romanticized the labor transfer and appropriated the collective experiences of migrants for their own political purposes. In this transnational business, the Korean Overseas Development Corporation (KODCO) and the DKG maintained exclusivity in the labor migration channel and were faithful to their own interests. The DKG, as a representative of the German healthcare industry, was concerned about being criticized for destroying the healthcare system of developing countries by stealing their skilled workforce. They, therefore, tried to influence publicity in Korea and Germany to persuade the people that the recruitment benefited both countries. However, the DKG was aware of the deceitfulness of its "development aid" discourse. The Korean government, which advanced the labor export for the sake of obtaining foreign currency, romanticized it as patriotism and used the term "German dispatchment." However, the incapacity and corruption of KODCO as an agency from the Korean perspective resulted in criticism regarding its recruitment program. The DKG complained that the selection of incapable personnel coupled with corruption was causing unforeseen financial damage to its member hospitals. Nevertheless, it officially defended its partner for the sake of its own interests, such as avoiding bad publicity and securing the sustainability of the recruitment program. The conflicts regarding nursing tasks and working conditions between Korean nurses and their German colleagues and employers captured in the documents of the DKG trace the origin of the issues in relation to cultural misunderstanding and pervasive racism. The disparity of state strength between the two countries resulted in the subaltern position of Korean female healthcare workers in the global labor market, and they tried to bring forth the best possible outcome while working in a foreign country in unfamiliar circumstances. However, the difficulties with female guest workers from Asia were generally credited to their inability to adhere to the German working style. This study contributes to the existing scholarship on this topic by filling the gaps. Historical research on the medical migration of Korean nurses and nurse-aides to West Germany has relied on limited historical sources. In 2013, the National Archives of Korea transferred official documents regarding these workers that were produced and archived by the DKG, which represented the interests of German healthcare institutions. Its documents on Korean nursing personnel provide supplementary information and display findings in different perspectives. They do not bring forth completely new findings that have never been researched before but are still valuable for delivering concrete evidence on the circumstances of that time, which were previously merely inferred. PMID- 30287725 TI - Examination of the Brain-Dead Organ Donor Management Process at a Spanish Hospital. AB - The number of donors and organs available has not increased at the same rate as the inclusion of new patients in the waiting lists. The aim of the present study was to analyze the quality of the detection process of potential brain-dead organ donors at the Hospital of Leon. For this, a cross-sectional prospective study was developed on a retrospective cohort of patients who were admitted or died by catastrophic brain damage with the potential for organs donation. Data were collected for six months using hospital records of admissions and exitus. For the statistical analysis, the free distribution software Epi Info 3.5.4 was employed. A total of 627 patients were studied: 550 were discharged and 77 died as potential donors. Of the potential donors, 65 died in asystole, but 60 of them had an absolute contraindication to donation and 20 died after limitation of life support therapy. Five cases with donor criteria in controlled asystole were detected. The analysis found that the detection process conformed to the regulatory framework stablished by the National Transplant Organization. However, population aging leads to a high rate of absolute contraindications among detected potential donors. The donation capacity of the hospital could therefore be increased with the implementation of a donor protocol in controlled asystole. PMID- 30287727 TI - Serum Carotenoids Reveal Poor Fruit and Vegetable Intake among Schoolchildren in Burkina Faso. AB - The health benefits of fruits and vegetables are well-documented. Those rich in provitamin A carotenoids are good sources of vitamin A. This cross-sectional study indirectly assessed fruit and vegetable intakes using serum carotenoids in 193 schoolchildren aged 7 to 12 years in the Western part of Burkina Faso. The mean total serum carotenoid concentration was 0.23 +/- 0.29 umol/L, which included alpha- and beta-carotene, lutein, and beta-cryptoxanthin, and determined with serum retinol concentrations in a single analysis with high performance liquid chromatography. Serum retinol concentration was 0.80 +/- 0.35 umol/L with 46% of children (n = 88) having low values <0.7 umol/L. Total serum carotene (the sum of alpha- and beta-carotene) concentration was 0.13 +/- 0.24 umol/L, well below the reference range of 0.9-3.7 umol carotene/L used to assess habitual intake of fruits and vegetables. Individual carotenoid concentrations were determined for alpha-carotene (0.01 +/- 0.05 umol/L), beta-carotene (0.17 +/- 0.24 umol/L), beta-cryptoxanthin (0.07 +/- 0.06 umol/L), and lutein (0.06 +/- 0.05 umol/L). These results confirm the previously measured high prevalence of low serum vitamin A concentrations and adds information about low serum carotenoids among schoolchildren suggesting that they have low intakes of provitamin A-rich fruits and vegetables. PMID- 30287726 TI - The Effect of Gluten-Free Diet on Health and the Gut Microbiota Cannot Be Extrapolated from One Population to Others. AB - Gluten-related disorders (GRD) affect millions of people worldwide and have been related to the composition and metabolism of the gut microbiota. These disorders present differently in each patient and the only treatment available is a strict life-long gluten-free diet (GFD). Several studies have investigated the effect of a GFD on the gut microbiota of patients afflicted with GRD as well as healthy people. The purpose of this review is to persuade the biomedical community to think that, while useful, the results from the effect of GFD on health and the gut microbiota cannot be extrapolated from one population to others. This argument is primarily based on the highly individualized pattern of gut microbial composition and metabolic activity in each person, the variability of the gut microbiota over time and the plethora of factors associated with this variation. In addition, there is wide variation in the composition, economic viability, and possible deleterious effects to health among different GFD, both within and among countries. Overall, this paper encourages the conception of more collaborative efforts to study local populations in an effort to reach biologically and medically useful conclusions that truly contribute to improve health in patients afflicted with GRD. PMID- 30287728 TI - Polish Validation of the SarQoL(r), a Quality of Life Questionnaire Specific to Sarcopenia. AB - Recently, SarQoL(r) (Sarcopenia and Quality of Life), a quality of life (QoL) questionnaire specific to sarcopenia, was successfully developed. For practical reasons, there is a great interest in validating this questionnaire in other populations. The aim of this cross-sectional study was to translate and adjust the SarQoL(r) into Polish and to standardize the validity of this method for the assessment of sarcopenic individuals in Poland with regard to psychometric properties. The English version was used for the translation process. A total of 106 community-dwelling Caucasian subjects aged 73.3 +/- 5.94 years (65.1% females) were studied, with 60 participants being diagnosed sarcopenic. The translation and cross-cultural adaptation was carried out in five phases according to specific standard guidelines. There were no major linguistic issues in the translation process. The data confirmed a good discriminant validity, i.e., significantly lower scores for all domains (reduced global QoL in sarcopenic subjects compared to non-sarcopenic ones; 54.9 +/- 16.5 vs. 63.3 +/- 17.1, p = 0.013), and high internal consistency (Cronbach's alpha coefficient was 0.92). The significant correlation of the SarQoL(r) scores with those of other questionnaires (SF-36v2(r) Health Survey and EuroQoL-5-Dimension) that are supposed to have similar dimensions indicated the consistent construct validity of the SarQoL(r)-PL questionnaire. No floor/ceiling effects were found. An excellent agreement was found between the test and the re-test (intraclass coefficient correlation (ICC): 0.99). The first Polish version of the SarQoL(r) questionnaire is valid and consistent and therefore may be used with reliability for clinical and research purposes regarding QoL assessment of sarcopenic individuals. However, further research, in particular prospective studies, is needed to determine potential limitations and the suitability of the new tool for the Polish scenario and specificity.

AB - Resveratrol is found in grapes, apples, blueberries, mulberries, peanuts, pistachios, plums and red wine. Resveratrol has been shown to possess antioxidative activity and a variety of preventive effects in models of many diseases. The aim of the study was to investigate if this substance may counteract the oxidative stress and polyol pathway in the lens of diabetic rats. The study was conducted on the rats with streptozotocin-induced type 1 diabetes. After the administration of resveratrol (10 and 20 mg/kg po for 4 weeks), the oxidative stress markers in the lens were evaluated: activity of superoxide dismutase, catalase and glutathione peroxidase, as well as levels of total and soluble protein, level of glutathione, vitamin C, calcium, sulfhydryl group, advanced oxidation protein products, malonyldialdehyde, Total Oxidant Status and Total Antioxidant Reactivity. The obtained results indicate that the administration of resveratrol to the diabetic rats shows antioxidative properties. It is not a result of antiglycaemic activity but resveratrol probably directly affects the antioxidative system. Resveratrol did not affect the polyol pathway in the lens of diabetic rats. Our results may indirectly indicate benefits of consumption of foods as well as dietary supplements containing resveratrol in diminishing oxidative stress in lenses of individuals suffering from diabetes mellitus. PMID- 30287731 TI - LncRNAs in TGF-beta-Driven Tissue Fibrosis. AB - Transforming growth factor-beta (TGF-beta) is a crucial mediator in tissue fibrosis that promotes accumulation of extracellular matrix (ECM), myofibroblasts to epithelial-mesenchymal transition (EMT), endothelial-mesenchymal transition (EndoMT), and apoptosis via canonical and noncanonical signaling pathways. In the past decades, a number of microRNAs have been reported to participate in TGF-beta mediated tissue scarring; however, the roles of long noncoding RNAs (lncRNAs) in fibrogenesis remain largely unknown. Recently, emerging evidence has shown that lncRNAs are involved in the development of different diseases, including cancer, autoimmune diseases, cardiovascular diseases, and fibrotic diseases. In this review, we summarize the current updates of lncRNAs in TGF-beta1-driven tissue fibrosis and discuss their therapeutic potential for the treatment of chronic fibrotic diseases. PMID- 30287730 TI - delta-Tocotrienol, Isolated from Rice Bran, Exerts an Anti-Inflammatory Effect via MAPKs and PPARs Signaling Pathways in Lipopolysaccharide-Stimulated Macrophages. AB - delta-Tocotrienol, an important component of vitamin E, has been reported to possess some physiological functions, such as anticancer and anti-inflammation, however their molecular mechanisms are not clear. In this study, delta tocotrienol was isolated and purified from rice bran. The anti-inflammatory effect and mechanism of delta-tocotrienol against lipopolysaccharides (LPS) activated pro-inflammatory mediator expressions in RAW264.7 cells were investigated. Results showed that delta-tocotrienol significantly inhibited LPS stimulated nitric oxide (NO) and proinflammatory cytokine (TNF-alpha, IFN-gamma, IL-1beta and IL-6) production and blocked the phosphorylation of c-Jun N-terminal kinase (JNK) and extracellular regulated protein kinases 1/2 (ERK1/2). delta Tocotrienol repressed the transcriptional activations and translocations of nuclear factor-kappa B (NF-kappaB) and activator protein-1 (AP-1), which were closely related with downregulated cytokine expressions. Meanwhile, delta tocotrienol also affected the PPAR signal pathway and exerted an anti inflammatory effect. Taken together, our data showed that delta-tocotrienol inhibited inflammation via mitogen-activated protein kinase (MAPK) and peroxisome proliferator-activated receptor (PPAR) signalings in LPS-stimulated macrophages. PMID- 30287732 TI - Adherence to Gluten-Free Diet in Children with Celiac Disease. AB - Celiac disease (CD) can only be treated by rigorous life-long gluten-free diet (GFD). The study included 102 mothers and their CD children treated with GFD for at least two years. Frequency and cause of diet failure in children treated at present (54 children) and 10 years ago (48 children) were compared. Dietary adherence was evaluated serologically (tTG), while diet management difficulties were examined by means of a questionnaire. The study shows that one-third of patients fail to follow GFD, more often 10 years ago than now (40% vs. 26%; p < 0.05), mainly children aged 13-18 (54% vs. 40% now; p < 0.05). Younger children (up to 12) are less likely to abandon the diet (27% vs. 8%; p < 0.05). In this age group non-intentional diet failure prevails, while teenagers interrupt their diet intentionally (45% vs. 33%; p = ns (small population of children in this groups)). Currently, the most common causes of teenage diet failure are the absence of symptoms after consuming a small amount of gluten and, even more often, troublesome diet administration. Previously, the absence of peer acceptance prevailed. With this study we found that: 1. In West Pomerania, every fourth CD child does not follow GFD. 2. For years, teenagers have failed to follow GFD due to the absence of symptoms after consuming small amounts of gluten. 3. The incidence of non-intentional failure to follow GFD has significantly decreased over years, which indicates better dietary care. PMID- 30287734 TI - Impact of Nutrition Education on the Compliance with Model Food Ration in 231 Preschools, Poland: Results of Eating Healthy, Growing Healthy Program. AB - To ensure the adequate supply of nutrients, a model food ration (MFR) should be used for planning the menu. The purpose of the study was to determine the effects of the nutrition education program on the compliance with MFR in 231 preschools. The average supply of food products (per child/day) with reference to the MFR was examined on the baseline and 3 to 6 months after education on the basis of 10-day menus and daily inventory reports (4620 in total). According to the recommendations, preschool should implement 70-75% of the recommended daily intake standards. Examined menus had too high content of meat and meat products, whereas vegetables, milk and fermented milk beverages, cottage cheese and eggs were served in scarce. Education significantly reduced the amount of meat (47.7 vs. 44.5 g), processed meat (16.2 vs. 14.4 g), sugar and sweets (15.9 vs. 14.4 g) and increased the amount of cereals, groats, rice (17.7 vs. 18.5 g), vegetables (164.3 vs. 170.8 g), milk and fermented milk beverages (200.3 vs. 209.5 g) but the compliance with the MFR remained poor. The evaluation of menus stressed the need for further modifying their composition. Education can positively affect the quality of nutrition; however, introduction of the legal nutritional regulations should be recommended. PMID- 30287733 TI - Achacha (Garcinia humilis) Rind Improves Cardiovascular Function in Rats with Diet-Induced Metabolic Syndrome. AB - Garcinia humilis is a fruit known as achachairu. It is native to South American countries such as Bolivia, Peru, and Brazil, but it is also cultivated as achacha in northern Australia. The aim of this study was to determine the phytochemicals in achacha rind and pulp and to investigate these components as potential treatments for the symptoms of metabolic syndrome. Both rind and pulp contain procyanidins and citric acid rather than hydroxycitric acid. Male Wistar rats (8 9 weeks old) were fed with either high-carbohydrate, high-fat, or corn starch diets for 16 weeks. Intervention groups were fed with either diet supplemented with 1.5% G. humilis rind powder or 2.0% G. humilis pulp for the last 8 weeks of the protocol. Rats fed a high-carbohydrate, high-fat diet exhibited hypertension, dyslipidemia, central obesity, impaired glucose tolerance, and non-alcoholic fatty liver disease. G. humilis rind decreased systolic blood pressure, diastolic stiffness, left ventricular inflammatory cell infiltration, and collagen deposition in high-carbohydrate, high-fat diet-fed rats. However, there was no change in glucose tolerance, body weight, or body composition. Therefore, G. humilis rind, usually a food by-product, but not the edible pulp, showed potential cardioprotection with minimal metabolic changes in a rat model of diet induced metabolic syndrome. PMID- 30287735 TI - Effects of Astaxanthin on the Proliferation and Migration of Breast Cancer Cells In Vitro. AB - Astaxanthin (ASX) is a marine-based ketocarotenoid; an accessory pigment in plants in that it has many different potential functions. ASX is an antioxidant that is notably more potent than many other antioxidants. Antioxidants have anti inflammatory and oxidative stress-reducing properties to potentially reduce the incidence of cancer or inhibit the expansion of tumor cells. In this study, we tested the hypothesis that ASX would inhibit proliferation and migration of breast cancer cells in vitro. We found that application of ASX significantly reduced proliferation rates and inhibited breast cancer cell migration compared to control normal breast epithelial cells. Based on these results, further investigation of the effects of ASX on not only breast cancer cells, but other forms of tumor cells, should be carried out. PMID- 30287736 TI - Addictive Eating and Its Relation to Physical Activity and Sleep Behavior. AB - The obesity epidemic has led to the exploration of factors contributing to its etiology. Addictive eating, physical activity, and sleep behaviors have all been independently associated with obesity, and recent research suggests plausible interrelationships between food addiction, physical activity, and sleep. This study aims to investigate the relationship between food addiction with physical activity and sleep behavior. Australian adults were invited to complete an online survey which collected information including: demographics, food addiction symptoms, physical activity, sitting time and sleep behavior items. The sample comprised 1344 individuals with a mean age of 39.8 +/- 13.1 years (range 18-91), of which 75.7% were female. Twenty-two percent of the sample met the criteria for a diagnosis of food addiction as per the Yale Food Addiction Scale (YFAS 2.0) criteria, consisting of 0.7% with a "mild" addiction, 2.6% "moderate", and 18.9% classified as having a "severe" food addiction. Food-addicted individuals had significantly less physical activity (1.8 less occasions walking/week, 32 min less walking/week, 58 min less moderate to vigorous physical activity (MVPA)/week; p < 0.05), reported sitting for longer on weekends (83 min more on weekends/week; p < 0.001), and reported significantly more symptoms of poorer quality sleep (more likely to snore, more likely to have fallen asleep while driving, reported more days of daytime falling asleep; p < 0.05) compared to non food-addicted individuals. These differences were also observed in those with a "severe" food addiction classification. The present study suggests frequency and duration of physical activity, time spent sitting and sleep duration are associated with food addiction. PMID- 30287738 TI - Thermal Energy Storage and Mechanical Performance of Crude Glycerol Polyurethane Composite Foams Containing Phase Change Materials and Expandable Graphite. AB - The aim of this study was to enhance the thermal comfort properties of crude glycerol (CG) derived polyurethane foams (PUFs) using phase change materials (PCMs) (2.5-10.0% (wt/wt)) to contribute to the reduction of the use of non renewable resources and increase energy savings. The main challenge when adding PCM to PUFs is to combine the low conductivity of PUFs whilst taking advantage of the heat released/absorbed by PCMs to achieve efficient thermal regulation. The solution considered to overcome this limitation was to use expandable graphite (EG) (0.50-1.50% (wt/wt)). The results obtained show that the use of PCMs increased the heterogeneity of the foams cellular structure and that the incorporation of PCMs and EG increased the stiffness of the ensuing composite PUFs acting as filler-reinforcing materials. However, these fillers also caused a substantial increase of the thermal conductivity and density of the ensuing foams which limited their thermal energy storage. Therefore, numerical simulations were carried using a single layer panel and the thermal and physical properties measured to evaluate the behavior of a composite PUF panel with different compositions, and guide future formulations to attain more effective results in respect to temperature buffering and temperature peak delay. PMID- 30287737 TI - A Novel Antithrombotic Protease from Marine Worm Sipunculus Nudus. AB - Sipunculus nudus, an old marine species, has great potential for use as functional seafood due to its various bioactivities. Its potential antithrombotic activity pushed us to isolate the bio-active components bio-guided by tracking fibrinolytic activity. As a result, a novel protease named as SK (the kinase obtained from S. nudus) was obtained, which possessed a molecular weight of 28,003.67 Da and 15 N-terminal amino acid sequences of PFPVPDPFVWDTSFQ. SK exerted inhibitory effects on thrombus formation through improving the coagulation system with dose-effect relationship within a certain range. Furthermore, in most cases SK got obviously better effect than that of urokinase. With the help of untargeted mass spectrometry-based metabolomics profiling, arachidonic acid, sphingolipid, and nicotinate and nicotinamide mechanism pathways were found to be important pathways. They revealed that the effect mechanism of SK on common carotid arterial thrombosis induced by FeCl3 was achieved by inhibiting vessel contraction, platelet aggregation, adhesion, and release, correcting endothelial cell dysfunction and retarding process of thrombus formation. This study demonstrated SK was a promising thrombolytic agent on the basis of its comprehensive activities on thrombosis, and it should get further exploitation and utilization. PMID- 30287739 TI - Non-Canonical Regulation of Type I Collagen through Promoter Binding of SOX2 and Its Contribution to Ameliorating Pulmonary Fibrosis by Butylidenephthalide. AB - Pulmonary fibrosis is a fatal respiratory disease that gradually leads to dyspnea, mainly accompanied by excessive collagen production in the fibroblast and myofibroblast through mechanisms such as abnormal alveolar epithelial cells remodeling and stimulation of the extracellular matrix (ECM). Our results show that a small molecule, butylidenephthalide (BP), reduces type I collagen (COL1) expression in Transforming Growth Factor beta (TGF-beta)-induced lung fibroblast without altering downstream pathways of TGF-beta, such as Smad phosphorylation. Treatment of BP also reduces the expression of transcription factor Sex Determining Region Y-box 2 (SOX2), and the ectopic expression of SOX2 overcomes the inhibitory actions of BP on COL1 expression. We also found that serial deletion of the SOX2 binding site on 3'COL1 promoter results in a marked reduction in luciferase activity. Moreover, chromatin immunoprecipitation, which was found on the SOX2 binding site of the COL1 promoter, decreases in BP-treated cells. In an in vivo study using a bleomycin-induced pulmonary fibrosis C57BL/6 mice model, mice treated with BP displayed reduced lung fibrosis and collagen deposition, recovering in their pulmonary ventilation function. The reduction of SOX2 expression in BP-treated lung tissues is consistent with our findings in the fibroblast. This is the first report that reveals a non-canonical regulation of COL1 promoter via SOX2 binding, and contributes to the amelioration of pulmonary fibrosis by BP treatment. PMID- 30287740 TI - Welsh Onion Root (Allium fistulosum) Restores Ovarian Functions from Letrozole Induced-Polycystic Ovary Syndrome. AB - Polycystic ovarian syndrome (PCOS) is an endocrine, metabolic, and systemic disease. It is mainly characterized by hyperandrogenism, oligomenorrhea, and high levels of luteinizing hormone (LH). There is no obvious therapy for PCOS, so patients have received symptomatic therapy. Welsh onion (Allium fistulosum) is well-known in Asian countries for its usage in food ingredients and traditional medicines. It is also studied for its many effects. These include activation of immune responses, antihypertensive effects, and antioxidant effects. Using letrozole-induced PCOS rats, we focused on herbal therapy using extract of Allium fistulosum (AF; A. fistulosum) roots to improve ovarian functions. As a nonsteroidal aromatase inhibitor, letrozole blocks conversion of testosterone to estrogen and subsequently induces PCOS phenomenon. We divided six-week-old female rats into four groups, including control, letrozole, letrozole + AF extract, and temporary letrozole groups. In our study, treatment with AF extract shows a low plasma LH/FSH ratio, and reveals high estrogen levels, ovarian morphology, folliculogenesis-related genes, and aromatase expression under PCOS mimic conditions. We concluded that AF extract administration influenced aromatase production, enhanced the estrogen steroid synthesis, and consequently restored the estrogenic feedback mechanism on the pituitary-ovary system. PMID- 30287741 TI - Association of Coffee Consumption with Hearing and Tinnitus Based on a National Population-Based Survey. AB - Coffee is the one of the most common beverages worldwide and has received considerable attention for its beneficial health effects. However, the association of coffee with hearing and tinnitus has not been well studied. The aim of this study was to investigate the association of coffee with hearing and tinnitus based on a national population-based survey. We evaluated hearing and tinnitus data from the 2009-2012 Korean National Health and Nutrition Examination Survey and their relationship with a coffee consumption survey. All patients underwent a medical interview, physical examination, hearing test, tinnitus questionnaire and nutrition examination. Multivariable logistic regression models were used to examine the associations between coffee and hearing loss or tinnitus. We evaluated 13,448 participants (>=19 years) participants. The frequency of coffee consumption had a statistically significant inverse correlation with bilateral hearing loss in the 40-64 years age group. Daily coffee consumers had 50-70% less hearing loss than rare coffee consumers, which tended to be a dose-dependent relationship. In addition, the frequency of coffee consumption had an inverse correlation with tinnitus in the 19-64 years age group but its association was related with hearing. Brewed coffee had more of an association than instant or canned coffee in the 40-64 years age group. These results suggest a protective effect of coffee on hearing loss and tinnitus. PMID- 30287743 TI - Plant Essential Oils Enhance Diverse Pyrethroids against Multiple Strains of Mosquitoes and Inhibit Detoxification Enzyme Processes. AB - Mosquito-borne diseases account for the deaths of approximately 700,000 people annually throughout the world, with many more succumbing to the debilitating side effects associated with these etiologic disease agents. This is exacerbated in many countries where the lack of mosquito control and resources to prevent and treat mosquito-borne disease coincide. As populations of mosquito species grow more resistant to currently utilized control chemistries, the need for new and effective chemical means for vector control is more important than ever. Previous work revealed that plant essential oils enhance the toxicity of permethrin against multiple mosquito species that are of particular importance to public health. In this study, we screened permethrin and deltamethrin in combination with plant essential oils against a pyrethroid-susceptible and a pyrethroid resistant strain of both Aedes aegypti and Anopheles gambiae. A number of plant essential oils significantly enhanced the toxicity of pyrethroids equal to or better than piperonyl butoxide, a commonly used synthetic synergist, in all strains tested. Significant synergism of pyrethroids was also observed for specific combinations of plant essential oils and pyrethroids. Moreover, plant essential oils significantly inhibited both cytochrome P450 and glutathione S transferase activities, suggesting that the inhibition of detoxification contributes to the enhancement or synergism of plant essential oils for pyrethroids. This study highlights the potential of using diverse plant oils as insecticide additives to augment the efficacy of insecticidal formulations. PMID- 30287742 TI - Potential Role for Osteocalcin in the Development of Atherosclerosis and Blood Vessel Disease. AB - There is increasing evidence for the involvement of the skeleton in the regulation of atherosclerotic vascular disease. Osteocalcin, an osteoblast derived protein, exists in two forms, carboxylated and undercarboxylated osteocalcin. Undercarboxylated osteocalcin has been linked to the regulation of metabolic functions, including glucose and lipid metabolism. Features of atherosclerosis have been associated with circulating osteocalcin; however, this association is often conflicting and unclear. Therefore, the aim of this review is to examine the evidence for a role of osteocalcin in atherosclerosis development and progression, and in particular endothelial dysfunction and vascular calcification. The current literature suggests that undercarboxylated osteocalcin stimulates the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) signaling pathway to upregulate nitric oxide and nuclear factor kappa beta (NF kbeta) in vascular cells, possibly protecting endothelial function and preventing atherogenesis. However, this effect may be mediated by metabolic factors, such as improvements in insulin signaling, rather than through a direct effect on the vasculature. Total osteocalcin is frequently associated with vascular calcification, an association that may occur as a result of vascular cells eliciting an osteogenic phenotype. Whether osteocalcin acts as a mediator or a marker of vascular calcification is currently unclear. As such, further studies that examine each form of osteocalcin are required to elucidate if it is a mediator of atherogenesis, and whether it functions independently of metabolic factors. PMID- 30287744 TI - River Management for Local Governments in China: From Public to Private. AB - The Public and Private Partnership (PPP) model has been used to provide public services and goods. In China, local governments are willing to use the PPP model in many public services, such as integrated river management (IRM) projects, due to ease fiscal budget and the improved access to technology from the private sector. However, there has not been any specific discussion in the literature for applying the PPP model to IRM projects. In this study, we find that the PPP model results in the non-standardization of IRM projects. Our research paper builds the PPP operation framework for IRM projects. Our findings suggest that while the environmental quality evaluation system created in contracts for government payment seems to be optimal for protecting the public interest, it actually strains the partnership between the two parties and so its implementation should be considered on a case by case basis. Since the history of IRM projects using the PPP model is short, the actual performances of these types of projects has not yet been demonstrated. Local governments should be cautious about adopting the PPP model for such projects, and private companies should be cautious about their involvement. Our research will garner more scholarly attention to the application of the PPP model in complex projects. PMID- 30287746 TI - Functionalized Gold Nanoparticles as Biosensors for Monitoring Cellular Uptake and Localization in Normal and Tumor Prostatic Cells. AB - In the present contribution the fabrication and characterization of functionalized gold nanospheres of uniform shape and controlled size is reported. These nano-objects are intended to be used as Surface Enhanced Raman Spectroscopy (SERS) sensors for in-vitro cellular uptake and localization. Thiophenol was used as molecular reporter and was bound to the Au surface by a chemisorption process in aqueous solution. The obtained colloidal solution was highly stable and no aggregation of the single nanospheres into larger clusters was observed. The nanoparticles were incubated in human prostatic cells with the aim of developing a robust, SERS-based method to differentiate normal and tumor cell lines. SERS imaging experiments showed that tumor cells uptake considerably larger amounts of nanoparticles in comparison to normal cells (up to 950% more); significant differences were also observed in the uptake kinetics. This largely different behaviour might be exploited in diagnostic and therapeutic applications. PMID- 30287745 TI - A Disposable Photovoltaic Patch Controlling Cellular Microenvironment for Wound Healing. AB - Electrical stimulation (ES) is known to affect the wound healing process by modulating skin cell behaviors. However, the conventional clinical devices that can generate ES for promoting wound healing require patient hospitalization due to large-scale of the extracorporeal devices. Herein, we introduce a disposable photovoltaic patch that can be applied to skin wound sites to control cellular microenvironment for promoting wound healing by generating ES. In vitro experiment results show that exogenous ES could enhance cell migration, proliferation, expression of extracellular matrix proteins, and myoblast differentiation of fibroblasts which are critical for wound healing. Our disposable photovoltaic patches were attached to the back of skin wound induced mice. Our patch successfully provided ES, generated by photovoltaic energy harvested from the organic solar cell under visible light illumination. In vivo experiment results show that the patch promoted cutaneous wound healing via enhanced host-inductive cell proliferation, cytokine secretion, and protein synthesis which is critical for wound healing process. Unlike the current treatments for wound healing that engage passive healing processes and often are unsuccessful, our wearable photovoltaic patch can stimulate regenerative activities of endogenous cells and actively contribute to the wound healing processes. PMID- 30287748 TI - Experimental Study on the Icing Dielectric Constant for the Capacitive Icing Sensor. AB - The capacitive method is considered to be a suitable icing-detection technology, but the lack of fundamental parameters restricts the development of icing detection sensors. In this paper, an artificial icing laboratory, a capacitive sensor, and some simulation conductors have been designed for obtaining the artificial icing samples. Subsequently, the same characteristic values of artificial icing have been measured by an LCR device, under a selected frequency. This research found that the value of the icing dielectric constant closely correlated with its density, internal sublayer, and the test temperature. Finally, a fitting formula has been presented for calculating the relative dielectric constant, which may provide some important reference value for the design of icing-detection sensors. PMID- 30287747 TI - Effect of Hydroxyapatite Formation on Titanium Surface with Bone Morphogenetic Protein-2 Loading through Electrochemical Deposition on MG-63 Cells. AB - Calcium phosphate ceramics used in dentistry and orthopedics are some of the most valuable biomaterials, owing to their excellent osteoconduction, osteoinduction, and osseointegration. Osteoconduction and osteoinduction are critical targets for bone regeneration, and osseointegration is essential for any dental implantations. In this study, a hydroxyapatite (HAp) hybrid coating layer with the sequential release of bone morphogenetic protein 2 (BMP-2) was deposited onto an etched titanium substrate by electrochemical deposition. The resulting release of BMP-2 from Ti-HAp was assessed by immersing samples in a simulated buffer fluid solution. Through coculture, human osteosarcoma cell proliferation and alkaline phosphatase activity were assessed. The characteristics and effect on cell proliferation of the hybrid coatings were investigated for their functionality through X-ray diffraction (XRD) and cell proliferation assays. Findings revealed that -0.8 V vs. Ag/AgCl (3 M KCl) exhibited the optimal HAp properties and a successfully coated HAp layer. XRD confirmed the crystallinity of the deposited HAp on the titanium surface. Ti-0.8 V Ti-HAp co-coating BMP sample exhibited the highest cell proliferation efficiency and was more favorable for cell growth. A successful biocompatible hybrid coating with optimized redox voltage enhanced the osseointegration process. The findings suggest that this technique could have promising clinical applications to enhance the healing times and success rates of dental implantation. PMID- 30287749 TI - Development of Eco-Friendly Polymer Foam Using Overcoat Technology of Deodorant. AB - Development of eco-friendly polymer foams is an urgent research topic because of the serious environmental pollution caused by trash heaps and the time-release of harmful gases. Polymer PVC foam using azodicarbonamide as a chemical foaming agent has been highly requested for further improvement due to the residual ammonia gas that continuously leaks out. Here, we demonstrate an effective and costless process for the reduction of releasing ammonia from PVC foams using the overcoat technology of deodorants. We have selected four candidate materials, gelite, zeolite, terra alba, and fumed silica as original materials for the deodorant of ammonia, and they showed an ammonia deodorization rate (ADR) of over 80% without any treatment except the fumed silica. When we over-coated the UV curing agent mixed deodorants on the PVC foams (thickness ~300 um), the ADR of the terra alba and zeolite complex foams was remarkably higher than 90%, however, the specific gravity and chromaticity were not changed within 20%. This indicates that our developed process using deodorant layer for ammonia reduction has a high potential for the production of eco-friendly polymer foams. PMID- 30287750 TI - Fetal Renal Echogenicity Associated with Maternal Focal Segmental Glomerulosclerosis: The Effect of Transplacental Transmission of Permeability Factor suPAR. AB - We report a case of a pregnant woman with nephrotic syndrome due to biopsy-proven focal segmental glomerulosclerosis (FSGS) whose fetus developed echogenic kidneys and severe oligohydramnios by 27 weeks of gestation. Maternal treatment with prednisone resulted in normalization of the amniotic fluid indices and resolution of fetal renal echogenicity. The newborn was noted to have transient renal dysfunction and proteinuria, resolving by 6 weeks postpartum. The transplacental passage of permeability factors is postulated to have caused both the fetal and newborn renal presentation, with significantly elevated levels of soluble urokinase-type plasminogen activator receptor (suPAR) noted in the cord blood. This case documents the transplacental maternal-fetal transmission of suPAR, demonstrating the potential for maternal-fetal transmission of deleterious, disease-causing entities, and adds to the differential diagnosis of fetal echogenic kidneys. Further, this is the first documentation of a fetal response to maternal systemic therapy. PMID- 30287752 TI - Nanoscale Assembly of Copper Bearing-Sleeve via Cold-Welding: A Molecular Dynamics Study. AB - A bearing is an important component in contemporary machinery and equipment, whose main function is to support the mechanical rotator, reduce the friction coefficient during its movement, and guarantee the turning accuracy. However, assembly of a nanoscale bearing and sleeve is a challenging process for micro nano mechanical manufacturers. Hence, we show the cold-welding mechanism of a copper nanobearing-nanosleeve via molecular dynamic simulations. We demonstrate that it is feasible to assemble a bearing and sleeve at the nanoscale to form a stable mechanism. The effect of temperature in the range of 150 to 750 K is investigated. As the temperature rises, the mechanical strength and the weld stress of the welded structures markedly decrease, accompanied by the observation of increasing disorder magnitude. This comparison study is believed to facilitate future mechanical processing and structural nano-assembly of metallic elements for better mechanical performance. PMID- 30287753 TI - Selenium and Selenoproteins in Immune Mediated Thyroid Disorders. AB - Selenium is an essential micronutrient that is required for the synthesis of selenocysteine-containing selenoproteins, processing a wide range of health effects. It is known that the thyroid is one of the tissues that contain more selenium. The "selenostasis" maintenance seems to contribute to the prevention of immune mediated thyroid disorders. Prospective, observational studies, randomized, controlled studies evaluating selenium supplementation, and review articles that are available in Medline and PubMed have undergone scrutiny. The differences concerning methodology and results variability have been analyzed. Several authors support the idea of a potential efficacy of selenium (mainly selenomethionine) supplementation in reducing antithyroperoxidase antibody levels and improve thyroid ultrasound features. In mild Graves' orbitopathy, selenium supplementation has been associated with a decrease of the activity, as well as with quality of life improvement. Future research is necessary to clearly understand the selenium supplementation biologic effects while considering the basal selenium levels/biomarkers, selenoprotein gene polymorphisms that may be involved, underlying comorbidities and the major clinical outcomes. PMID- 30287751 TI - The Westward Journey of Alfalfa Leaf Curl Virus. AB - Alfalfa leaf curl virus (ALCV), which causes severe disease symptoms in alfalfa (Medicago sativa L.) and is transmitted by the widespread aphid species, Aphis craccivora Koch, has been found throughout the Mediterranean basin as well as in Iran and Argentina. Here we reconstruct the evolutionary history of ALCV and attempt to determine whether the recent discovery and widespread detection of ALCV is attributable either to past diagnostic biases or to the emergence and global spread of the virus over the past few years. One hundred and twenty ALCV complete genome sequences recovered from ten countries were analyzed and four ALCV genotypes (ALCV-A, ALCV-B, ALCV-C, and ALCV-D) were clearly distinguished. We further confirm that ALCV isolates are highly recombinogenic and that recombination has been a major determinant in the origins of the various genotypes. Collectively, the sequence data support the hypothesis that, of all the analyzed locations, ALCV likely emerged and diversified in the Middle East before spreading to the western Mediterranean basin and Argentina. PMID- 30287755 TI - Long-Term Biogas Production from Glycolate by Diverse and Highly Dynamic Communities. AB - Generating chemical energy carriers and bulk chemicals from solar energy by microbial metabolic capacities is a promising technology. In this long-term study of over 500 days, methane was produced by a microbial community that was fed by the mono-substrate glycolate, which was derived from engineered algae. The microbial community structure was measured on the single cell level using flow cytometry. Abiotic and operational reactor parameters were analyzed in parallel. The R-based tool flowCyBar facilitated visualization of community dynamics and indicated sub-communities involved in glycolate fermentation and methanogenesis. Cell sorting and amplicon sequencing of 16S rRNA and mcrA genes were used to identify the key organisms involved in the anaerobic conversion process. The microbial community allowed a constant fermentation, although it was sensitive to high glycolate concentrations in the feed. A linear correlation between glycolate loading rate and biogas amount was observed (R2 = 0.99) for glycolate loading rates up to 1.81 g L-1 day-1 with a maximum in biogas amount of 3635 mL day-1 encompassing 45% methane. The cytometric diversity remained high during the whole cultivation period. The dominating bacterial genera were Syntrophobotulus, Clostridia genus B55_F, Aminobacterium, and Petrimonas. Methanogenesis was almost exclusively performed by the hydrogenotrophic genus Methanobacterium. PMID- 30287754 TI - DNA Methylation as a Biomarker of Treatment Response Variability in Serious Mental Illnesses: A Systematic Review Focused on Bipolar Disorder, Schizophrenia, and Major Depressive Disorder. AB - So far, genetic studies of treatment response in schizophrenia, bipolar disorder, and major depression have returned results with limited clinical utility. A gene * environment interplay has been proposed as a factor influencing not only pathophysiology but also the treatment response. Therefore, epigenetics has emerged as a major field of research to study the treatment of these three disorders. Among the epigenetic marks that can modify gene expression, DNA methylation is the best studied. We performed a systematic search (PubMed) following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA guidelines for preclinical and clinical studies focused on genome-wide and gene-specific DNA methylation in the context of schizophrenia, bipolar disorders, and major depressive disorder. Out of the 112 studies initially identified, we selected 31 studies among them, with an emphasis on responses to the gold standard treatments in each disorder. Modulations of DNA methylation levels at specific CpG sites have been documented for all classes of treatments (antipsychotics, mood stabilizers, and antidepressants). The heterogeneity of the models and methodologies used complicate the interpretation of results. Although few studies in each disorder have assessed the potential of DNA methylation as biomarkers of treatment response, data support this hypothesis for antipsychotics, mood stabilizers and antidepressants.

AB - Graphene nanoplatelet (GNP) and multi-walled carbon nanotube (MWCNT) hybrid films were prepared with the aid of surfactant Triton X-100 and sonication through a vacuum filtration process. The influence of GNP content ranging from 0 to 50 wt.% on the mechanical and electrical properties was investigated using the tensile test and Hall effect measurement, respectively. It showed that the tensile strength of the hybrid film is decreasing with the increase of the GNP content while the electrical conductivity exhibits an opposite trend. The effectiveness of the MWCNT/GNP hybrid film as a strain sensor is presented. The specimen is subjected to a flexural loading, and the electrical resistance measured by a two point probe method is found to be function of applied strain. Experimental results demonstrate that there are two different linear strain-sensing stages (0 0.2% and 0.2-1%) in the resistance of the hybrid film with applied strain. The strain sensitivity is increasing with the increase of the GNP content. In addition, the repeatability and stability of the strain sensitivity of the hybrid film were conformed through the cyclic loading-unloading tests. The MWCNT/GNP hybrid film shows promising application for strain sensing. PMID- 30287758 TI - Reducing Stress Susceptibility of Broiler Chickens by Supplementing a Yeast Fermentation Product in the Feed or Drinking Water. AB - Reducing stress is an important goal in animal production. Previous research has demonstrated the ability of Original XPCTM to reduce the stress response of broilers during heat stress. Three trials were conducted to evaluate the effects of adding Original XPCTM to the feed or AviCareTM to the water on stress susceptibility of broiler chickens. Treatments included: control nonstressed (CNS), control stressed (CS), stressed with Original XPCTM (1.25 kg/metric ton feed, 0-42 days; XPC), and stressed with AviCareTM (160 mL/100 L drinking water, 0-42 days; AVI). All stressed treatments received the following stressors: live coccidiosis vaccination (day 1), reared on reused litter (days 0-42), and heat stress with feed/water withdrawal (12 h on day 18). Plasma corticosterone and heterophil/lymphocyte (H/L) ratio were determined from 60 birds/T on day 19, and 24 birds/T on day 41. Physical asymmetry was determined using bilateral bone measurements from 60 birds/T on day 41. Birds provided XPC or AVI had lower corticosterone and H/L ratios than CS (p < 0.05) on day 19 and lower corticosterone, H/L ratios, and asymmetry scores than both CNS and CS on day 41 (p < 0.05) in all three trials. Supplementing XPC or AVI improved broiler welfare measured by reduced stress indicators after acute heat stress or normal rearing stress in all trials.

AB - The service time of an industrial cracker is strongly dependent on the long-term coking behavior and microstructure stability of the reactor coil alloy. Super alloys are known to withstand temperatures up to even 1400 K. In this work, several commercially available alloys have been first exposed to a long term oxidation at 1423 K for 500 h, so-called metallurgic aging. Subsequently, their coking behavior was evaluated in situ in a thermogravimetric setup under ethane steam cracking conditions (Tgasphase = 1173 K, Ptot = 0.1 MPa, XC2H6 = 70%, continuous addition of 41 ppmw S/HC of DMDS, dilution delta = 0.33 kgH2O/kgHC) and compared with their unaged coking behavior. The tested samples were also examined using scanning electron microscopy and energy diffractive X-ray for surface and cross-section analysis. The alloys characterized by increased Cr-Ni content or the addition of Al showed improved stability against bulk oxidation and anti-coking behavior after application of metallurgic aging due to the formation of more stable oxides on the top surface. PMID- 30287757 TI - The Anticancer Properties of Cordycepin and Their Underlying Mechanisms. AB - Cordyceps is a genus of ascomycete fungi that has been used for traditional herbal remedies. It contains various bioactive ingredients including cordycepin. Cordycepin, also known as 3-deoxyadenosine, is a major compound and has been suggested to have anticancer potential. The treatment of various cancer cells with cordycepin in effectively induces cell death and retards their cancerous properties. However, the underlying mechanism is not fully understood. Recent evidence has shed light on the molecular pathways involving cysteine-aspartic proteases (caspases), mitogen-activated protein kinases (MAPKs), and glycogen synthase kinase 3 beta (GSK-3beta). Furthermore, the pathways are mediated by putative receptors, such as adenosine receptors (ADORAs), death receptors (DRs), and the epidermal growth factor receptor (EGFR). This review provides the molecular mechanisms by which cordycepin functions as a singular or combinational anticancer therapeutic agent. PMID- 30287760 TI - Genistein Loaded Nanofibers Protect Spinal Cord Tissue Following Experimental Injury in Rats. AB - Innovative drug-delivery systems offer a unique approach to effectively provide therapeutic drug dose over the needed time to achieve better tissue protection and enhanced recovery. The hypothesis of the current study was to test the antioxidant and anti-inflammatory effects of genistein and nanofibers on the spinal cord tissue following experimental spinal cord injury (SCI). Rats were treated post SCI with genistein that is loaded on chitosan/polyvinyl alcohol (CS/PVA) nanofibers as an implantable drug-delivery system. SCI caused marked oxidative damage and inflammation, as is evident by the reduction in the super oxide dismutase (SOD) activity and the level of interleukin-10 (IL-10) in injured spinal cord tissue, as well as the significant increase in the levels of nitric oxide (NO), malondialdehyde (MDA), and tumor necrosis factor-alpha (TNF-alpha). Treatment of rats post SCI with genistein and CS/PVA nanofibers improved most of the above-mentioned biochemical parameters and shifted them toward the control group values. Genistein induced an increase in the activity of SOD and the level of IL-10, while causing a decrease in NO, MDA, and TNF-alpha in injured spinal cord tissue. Genistein and CS/PVA nanofibers provide a novel combination for treating inflammatory nervous tissue conditions, especially when combined as an implantable drug-delivery system. PMID- 30287761 TI - The Effect of Statin Added to Systemic Anticancer Therapy: A Meta-Analysis of Randomized, Controlled Trials. AB - Preclinical studies have demonstrated that statins have anticancer properties and act in an additive or synergistic way when combined with anticancer therapy. We conducted this meta-analysis of randomized, controlled phase II or III trials to evaluate the effect of statins added to systemic anticancer therapy in patients with solid cancer. A systematic literature search was performed to identify all randomized trials that were designed to investigate the effect of statins in patients with cancer using PubMed, EMBASE, Google Scholar, and Web of Science (up to August 2018). From eight randomized controlled trials, 1760 patients were included in the pooled analyses of odds ratios (ORs) with 95% confidence intervals (CIs) for grade 3-5 adverse events (AEs) and overall response rate (ORR) and hazard ratios (HRs) with 95% CIs for progression-free survival (PFS) and overall survival (OS). The addition of statin to anticancer agents did not significantly increase the incidence of grade 3-5 AEs (OR = 1.03, 95% CI: 0.81 1.29, p = 0.78). However, the combination of statin and anticancer agents did not improve ORR (OR = 0.96, 95% CI: 0.77-1.20, p = 0.72) compared with that of anticancer therapy alone. In addition, statins added to systemic anticancer therapy failed to prolong PFS (HR = 0.99, 95% CI: 0.90-1.10, p = 0.92) and OS (HR = 0.91, 95% CI: 0.76-1.11, p = 0.52). In conclusion, this meta-analysis of randomized controlled trials does not support clinical benefits of statins added to systemic anticancer therapy in patients with solid cancer. PMID- 30287762 TI - Impact of Mixed Equine Influenza Vaccination on Correlate of Protection in Horses. AB - To evaluate the humoral immune response to mixed Equine Influenza vaccination, a common practice in the field, an experimental study was carried out on 42 unvaccinated thoroughbred weanling foals divided into six groups of seven. Three groups were vaccinated using a non-mixed protocol (Equilis(r) Prequenza-Te, Proteqflu-Te(r) or Calvenza-03(r)) and three other groups were vaccinated using a mix of the three vaccines mentioned previously. Each weanling underwent a primary EI vaccination schedule composed of two primary immunisations (V1 and V2) four weeks apart followed by a third boost immunisation (V3) six months later. Antibody responses were monitored until one-year post-V3 by single radial haemolysis (SRH). The results showed similar antibody responses for all groups using mixed EI vaccination and the group exclusively vaccinated with Equilis(r) Prequenza-TE, which were significantly higher than the other two groups vaccinated with Proteqflu-TE(r) and Calvenza-03(r). All weanlings (100%) failed to seroconvert after V1 and 21% (9/42) still had low or no SRH antibody titres two weeks post-V2. All weanlings had seroconverted and exceeded the clinical protection threshold one month after V3. The poor response to vaccination was primarily observed in groups exclusively vaccinated with Proteqflu-Te(r) and Calvenza-03(r). A large window of susceptibility (3-4.5-month duration) usually called immunity gap was observed after V2 and prior to V3 for all groups. The SRH antibody level was maintained above the clinical protection threshold for three months post-V3 for the groups exclusively vaccinated with Proteqflu-Te(r) and Calvenza-03(r), and six months to one year for groups using mixed EI vaccination or exclusively vaccinated with Equilis(r) Prequenza-Te. This study demonstrates for the first time that the mix of EI vaccines during the primary vaccination schedule has no detrimental impact on the correlate of protection against EIV infection. PMID- 30287764 TI - Anthropometric Status among 6-9-Year-Old School Children in Rural Areas in Hai Phong City, Vietnam. AB - A double burden of malnutrition in Vietnamese children has emerged as a key challenge: childhood undernutrition remains a public health concern while childhood overweight/obesity has gradually increased. This study aimed to (1) estimate the prevalence of undernutrition and overnutrition among 6-9-year-old primary school children in rural areas of Vietnam, and (2) identify sociodemographic factors associated with undernutrition and overnutrition in this population. A cross-sectional survey was conducted in October 2016 in 2334 children from eight primary schools in rural areas in Hai Phong City, Vietnam. Anthropometric and demographic data were collected. The prevalence of underweight, stunting, wasting, and anthropometric failure was 8.0%, 5.1%, 5.3%, and 11.9%, respectively. Up to 22.1% of children were affected by overweight/obesity, and 31.0% by abdominal overweight/obesity. Low maternal education was associated with higher odds of underweight and anthropometric failure, whereas overweight/obesity or abdominal overweight/obesity were more likely in boys and children of mothers with a high education level. This study provides evidence for a double burden of diseases among primary school children in rural areas in Hai Phong City. Future interventions for the prevention and control of childhood undernutrition and overweight/obesity should take into account child sex and maternal education level. PMID- 30287765 TI - Spin-Coated CH3NH3PbBr3 Film Consisting of Micron-Scale Single Crystals Assisted with a Benzophenone Crystallizing Agent and Its Application in Perovskite Light Emitting Diodes. AB - Owing to the superior properties of optical and electronic properties, perovskite single crystals have been in high demand recently. However, the growth of large sized single crystals requires several processing steps and a long growth time, which engenders great difficulties in device integration. Herein, benzophenone (BP) was firstly introduced as a crystallizing agent to facilitate the construction of a high-quality CH3NH3PbBr3 (MAPbBr3) film consisting of micron scale single crystals in a one-step spin-coating method. We studied the influence of the BP concentration upon the size and shape of the micron-scale single crystals. Moreover, due to the enhanced morphology of the MAPbBr3 film with low defect micron-scale single crystals, perovskite light-emitting diodes (PeLEDs) have been demonstrated with a maximum luminance of 1057.6 cd/m2 and a turn-on voltage as low as 2.25 V. This approach not only proposes a concise and highly repeatable method for the formation of micron-scale perovskite single crystals, but also paves a way for the realization of efficient PeLEDs. PMID- 30287766 TI - Effect of Educational Interventions on Understanding and Use of Nutrition Labels: A Systematic Review. AB - The potential for nutrition labels to impact on population health is dependent on consumer ability to understand and use this information. Consumer understanding of this information varies across sociodemographic groups and with different label design formats. Labeling legislation requires consumer education on how to use nutrition labels, and recent mandatory changes to the Nutrition Facts Panel (NFP) are underway to improve comprehensibility. This review aimed to evaluate if educational programs can improve understanding and use of nutrition labels. Database searches were performed to identify interventions which delivered education on nutrition labels with outcomes measuring aspects of comprehension or use. A total of 17 studies were selected for review, including nine randomized and eight cohort studies. The majority of studies were conducted in the United States Study participants included school aged children, older adults, and those with diabetes within a range of intervention types involving taught sessions or web-based education. Whilst outcome measures were heterogenous, all studies reported a statistically significant improvement in one or more outcomes of participant understanding or use of nutrition labels. Aspects such as general nutrition knowledge, health literacy, and program delivery format warrant attention in future research. Education which optimizes comprehension and use of nutrition labels may have the potential to improve the impact of this information on dietary health. PMID- 30287768 TI - Reliability of X7R Multilayer Ceramic Capacitors During High Accelerated Life Testing (HALT). AB - Multilayer ceramic capacitors (MLCC) are essential components for determining the reliability of electronic components in terms of time to failure. It is known that the reliability of MLCCs depends on their composition, processing, and operating conditions. In this present work, we analyzed the lifetime of three similar X7R type MLCCs based on BaTiO3 by conducting High Accelerated Life Tests (HALT) at temperatures up to 200 degrees C at 400 V and 600 V. The results were adjusted to an Arrhenius equation, which is a function of the activation energy (Ea) and a voltage stress exponent (n), in order to predict their time to failure. The values of Ea are in the range of 1-1.45 eV, which has been reported for the thermal failure and dielectric wear out of BaTiO3-based dielectric capacitors. The stress voltage exponent value was in the range of 4-5. Although the Ea can be associated with a failure mechanism, n only gives an indication of the effect of voltage in the tests. It was possible to associate those values with each type of tested MLCC so that their expected life could be estimated in the range of 400-600 V. PMID- 30287763 TI - Role of Extracellular Matrix in Development and Cancer Progression. AB - The immense diversity of extracellular matrix (ECM) proteins confers distinct biochemical and biophysical properties that influence cell phenotype. The ECM is highly dynamic as it is constantly deposited, remodelled, and degraded during development until maturity to maintain tissue homeostasis. The ECM's composition and organization are spatiotemporally regulated to control cell behaviour and differentiation, but dysregulation of ECM dynamics leads to the development of diseases such as cancer. The chemical cues presented by the ECM have been appreciated as key drivers for both development and cancer progression. However, the mechanical forces present due to the ECM have been largely ignored but recently recognized to play critical roles in disease progression and malignant cell behaviour. Here, we review the ways in which biophysical forces of the microenvironment influence biochemical regulation and cell phenotype during key stages of human development and cancer progression. PMID- 30287767 TI - Chaperones, Canalization, and Evolution of Animal Forms. AB - Over half a century ago, British developmental biologist Conrad Hal Waddington proposed the idea of canalization, that is, homeostasis in development. Since the breakthrough that was made by Rutherford and Lindquist (1998), who proposed a role of Hsp90 in developmental buffering, chaperones have gained much attention in the study of canalization. However, recent studies have revealed that a number of other molecules are also potentially involved in canalization. Here, I introduce the emerging role of DnaJ chaperones in canalization. I also discuss how the expression levels of such buffering molecules can be altered, thereby altering organismal development. Since developmental robustness is maternally inherited in various organisms, I propose that dynamic bet hedging, an increase in within-clutch variation in offspring phenotypes that is caused by unpredictable environmental challenges to the mothers, plays a key role in altering the expression levels of buffering molecules. Investigating dynamic bet hedging at the molecular level and how it impacts upon morphological phenotypes will help our understanding of the molecular mechanisms of canalization and evolutionary processes. PMID- 30287769 TI - Analysis of Heavy Metal Sources in the Soil of Riverbanks Across an Urbanization Gradient. AB - Regional soil quality issues arising from rapid urbanization have received extensive attention. The riverbank that runs through a city is representative of urbanization gradient transformation. Thirty soil samples in the Yangtze River Delta urban agglomeration were collected and analyzed for the concentrations of seven analytes. Correlation, principle component analysis, cluster analysis and GeoDetector models suggested that the four groups (Cr-Ni-Cu, Cu-Zn-As-Sb, Cd and Pb) shared the same sources in the core urban region; five groups (Cr-Ni-Cu-Zn, As, Cd, Sb and Pb) in the suburbs and three groups (Cr-Ni, Cu-Zn-Cd-Sb-Pb and As) in the exurbs. GeoDetector methods not only validated the results of the three other methods, but also provided more possible impact factors. Besides the direct influences, the interaction effects among factors were quantified. Interactive combination with strong nonlinear increment changed from between-two-weak factors in the central region to between-strong-and-weak factors in the suburbs. In the exurbs, the stronger interaction effects were observed between strong and weak factors. Therefore, the GeoDetector model, which provided more detailed information of artificial sources could be used as a tool for identifying the potential factors of toxic elements and offering scientific basis for the development of subsequent pollution reduction strategies. PMID- 30287770 TI - The Characterization of Immunoprotection Induced by a cDNA Clone Derived from the Attenuated Taiwan Porcine Epidemic Diarrhea Virus Pintung 52 Strain. AB - The porcine epidemic diarrhea virus (PEDV) poses a great threat to the global swine industries and the unreliable protection induced by the currently available vaccines remains a major challenge. We previously generated a genogroup 2b (G2b) PEDV Taiwan Pintung 52 (PEDVPT) strain, PEDVPT-P96, and determined its promising host immune response against the virulent PEDVPT-P5 strain. To study the attenuation determinants of PEDVPT-P96 and establish a PEDVPT-P96-based recombinant vector as a vaccine platform for further antigenicity modification, iPEDVPT-P96, a full-length cDNA clone of PEDVPT-P96, was established. Comparing to the parental PEDVPT-P96 virus, the iPEDVPT-P96 virus showed efficient replication kinetics with a delayed decline of viral load and similar but much more uniform plaque sizes in Vero cells. In the 5-week-old piglet model, fecal viral shedding was observed in the PEDVPT-P96-inoculated piglets, whereas those inoculated with iPEDVPT-P96 showed neither detectable fecal viral shedding nor PEDV-associated clinical signs. Moreover, inoculation with iPEDVPT-P96 elicited comparable levels of anti-PEDV specific plasma IgG and fecal/salivary IgA, neutralizing antibody titers, and similar but less effective immunoprotection against the virulent PEDVPT-P5 challenge compared to the parental PEDVPT-P96. In the present study, an infectious cDNA clone of an attenuated G2b PEDV strain was successfully generated for the first time, and the in vitro and in vivo data indicate that iPEDVPT-P96 is further attenuated but remains immunogenic compared to its parental PEDVPT-P96 viral stock. The successful development of the iPEDVPT P96 cDNA clone could allow for the manipulation of the viral genome to study viral pathogenesis and facilitate the rapid development of effective vaccines. PMID- 30287771 TI - Demographics Regarding Belief in Non-Human Animal Sentience and Emotional Empathy with Animals: A Pilot Study among Attendees of an Animal Welfare Symposium. AB - Attitudes to animals are linked to beliefs about their ability to experience pain and suffering, their cognition, and their sentience. Education and awareness raising play a pivotal role in increasing society's consideration of non-human animal welfare. The current pilot study explores the attitudes towards animal welfare among a unique population of people who attended an animal welfare symposium at the University of Sydney. It involved administration of a validated questionnaire that assessed attitudes to animals; specifically exploring participants' (n = 41) beliefs about the sentience of animals and their emotional empathy with animals. The resultant data revealed significant associations between participants' beliefs in animal sentience and their demographic variables (age, sex and occupation). Female attendees showed stronger beliefs in sentience than male attendees did. Concerning sentience in cows, pigs and cats, older attendees showed stronger beliefs than younger people in sentience relating to hunger and pain. Also, with regard to questions about sentience in dogs, older attendees showed stronger beliefs than younger people in pain-related sentience in dogs. When exploring emotional empathy with animals, the participants' statements could be assigned to three clusters characterised by the internal emotional lives of animals and the treatment of animals by humans (Cluster 1), human interactions with animals (Cluster 2) and the keeping of companion and zoo animals (Cluster 3). To the authors' knowledge, this pilot study is the first of its kind to investigate the attitudes towards animal welfare of an important group of people who work, study or have a special interest within the animal care and welfare domain. PMID- 30287773 TI - Advances in Magnetic Nanoparticles-Supported Palladium Complexes for Coupling Reactions. AB - Carbon-carbon (C-C) and carbon-heteroatom (C-X) bonds that form via transition metal-catalyzed processes have been extensively used in the organic synthesis and preparation of natural products and important compounds such as heterocycles, biologically active molecules, and dendrimers. Among the most significant catalysts, magnetic nanoparticles-supported palladium complexes are very effective, versatile, and heterogeneous catalysts for a wide range of C-C and C-X coupling reactions due to their reusability, thermal stability, and excellent catalytic performance. In this review, recent advances to develop magnetic nanoparticles supported palladium complexes, including their preparation, characterization, catalytic application, and reusability in the formation of both C-C and C-X bonds, by authors such as Sonogashira, Heck, Suzuki-Miyaura, and Stille, and a few examples concerning N-arylation, S-arylation, and Csp2-P coupling reactions are discussed. PMID- 30287774 TI - A Lightweight Cipher Based on Salsa20 for Resource-Constrained IoT Devices. AB - The Internet of Things (IoT) paradigm envisions a world where everyday things interchange information between each other in a way that allows users to make smarter decisions in a given context. Even though IoT has many advantages, its characteristics make it very vulnerable to security attacks. Ciphers are a security primitive that can prevent some of the attacks; however, the constrained computing and energy resources of IoT devices impede them from implementing current ciphers. This article presents the stream cipher Generador de Bits Pseudo Aleatorios (GBPA) based on Salsa20 cipher, which is part of the eSTREAM project, but designed for resource-constrained IoT devices of Class 0. GBPA has lower program and data memory requirements compared with Salsa20 and lightweight ciphers. These properties allow low-cost resource-constrained IoT devices, 29.5% of the embedded systems in the market, to be able to implement a security service that they are currently incapable of, to preserve the user's data privacy and protect the system from attacks that could damage it. For the evaluation of its output, three statistical test suites were used: NIST Statistical Test Suite (STS), DIEHARD and EACirc, with good results. The GBPA cipher provides security without having a negative impact on the computing resources of IoT devices. PMID- 30287772 TI - Nanoporous Anodic Alumina Photonic Crystals for Optical Chemo- and Biosensing: Fundamentals, Advances, and Perspectives. AB - Optical sensors are a class of devices that enable the identification and/or quantification of analyte molecules across multiple fields and disciplines such as environmental protection, medical diagnosis, security, food technology, biotechnology, and animal welfare. Nanoporous photonic crystal (PC) structures provide excellent platforms to develop such systems for a plethora of applications since these engineered materials enable precise and versatile control of light-matter interactions at the nanoscale. Nanoporous PCs provide both high sensitivity to monitor in real-time molecular binding events and a nanoporous matrix for selective immobilization of molecules of interest over increased surface areas. Nanoporous anodic alumina (NAA), a nanomaterial long envisaged as a PC, is an outstanding platform material to develop optical sensing systems in combination with multiple photonic technologies. Nanoporous anodic alumina photonic crystals (NAA-PCs) provide a versatile nanoporous structure that can be engineered in a multidimensional fashion to create unique PC sensing platforms such as Fabry-Perot interferometers, distributed Bragg reflectors, gradient-index filters, optical microcavities, and others. The effective medium of NAA-PCs undergoes changes upon interactions with analyte molecules. These changes modify the NAA-PCs' spectral fingerprints, which can be readily quantified to develop different sensing systems. This review introduces the fundamental development of NAA-PCs, compiling the most significant advances in the use of these optical materials for chemo- and biosensing applications, with a final prospective outlook about this exciting and dynamic field. PMID- 30287775 TI - Evaluation of A Concentrated Preterm Formula as a Liquid Human Milk Fortifier in Preterm Babies at Increased Risk of Feed Intolerance. AB - There are concerns around safety and tolerance of powder human milk fortifiers to optimize nutrition in preterm infants. The purpose of this study was to evaluate the tolerance and safety of a concentrated preterm formula (CPF) as a liquid human milk fortifier (HMF) for premature infants at increased risk of feeding intolerance. We prospectively enrolled preterm infants over an 18-month period, for whom a clinical decision had been made to add CPF to human milk due to concerns regarding tolerance of powder HMF. Data on feed tolerance, anthropometry, and serum biochemistry values were recorded. Serious adverse events, such as mortality, necrotizing enterocolitis (NEC), and sepsis, were monitored. A total of 29 babies received CPF fortified milk during the study period. The most common indication for starting CPF was previous intolerance to powder HMF. Feeding intolerance was noted in 4 infants on CPF. The growth velocity of infants was satisfactory (15.9 g/kg/day) after addition of CPF to feeds. The use of CPF as a fortifier in preterm babies considered at increased risk for feed intolerance seems well tolerated and facilitates adequate growth. Under close nutrition monitoring, this provides an additional option for human milk fortification in this challenging subgroup of preterm babies, especially in settings with limited human milk fortifier options. PMID- 30287776 TI - Lipopolysaccharide Challenge Reveals Hypothalamic-Pituitary-Adrenal Axis Dysfunction in Murine Systemic Lupus Erythematosus. AB - Crosstalk between the brain and innate immune system may be dysregulated in systemic lupus erythematosus (SLE), a chronic autoimmune disease that presents with dysautonomia and aberrant inflammation. The hypothalamic-pituitary-adrenal (HPA) axis is an endogenous neuro-endocrine-immune pathway that can regulate inflammation following activation of vagal afferents. We hypothesized that chronic inflammatory processes in SLE are in part due to HPA axis dysfunction, at the level of either the afferent vagal-paraventricular nuclei (PVN) interface, the anterior pituitary, and/or at the adrenal glands. To study this, we challenged female control and SLE mice with lipopolysaccharide (LPS) and measured c-Fos expression as an index of neuronal activation, plasma adrenocorticotrophic hormone (ACTH) as an index of anterior pituitary function, and plasma corticosterone as an index of adrenal function. We found that c-Fos expression in the PVN, and plasma ACTH and corticosterone were comparable between unchallenged SLE and control mice. PVN c-Fos was increased similarly in control and SLE mice three hours after LPS challenge; however, there were no changes in plasma ACTH amongst any experimental groups post inflammatory challenge. Plasma corticosterone was markedly increased in LPS-challenged SLE mice compared to their vehicle-treated counterparts, but not in controls. Paradoxically, following LPS challenge, brain and spleen TNF-alpha were elevated in LPS-challenged SLE mice despite heightened plasma corticosterone. This suggests that, despite normal c-Fos expression in the PVN and activation of the HPA axis following LPS challenge, this cumulative response may not adequately defend SLE mice against inflammatory stimuli, leading to abnormally heightened innate immune responses and peripheral inflammation. PMID- 30287778 TI - Assessment of a Rabies Virus Rapid Diagnostic Test for the Detection of Australian Bat Lyssavirus. AB - Australian bat lyssavirus (ABLV) is closely related to the classical rabies virus and has been associated with three human fatalities and two equine fatalities in Australia. ABLV infection in humans causes encephalomyelitis, resulting in fatal disease, but has no effective therapy. The virus is maintained in enzootic circulation within fruit bats (Pteropid spp.) and at least one insectivorous bat variety (Saccolaimus flaviventris). Most frequently, laboratory testing is conducted on pteropodid bat brains, either following a potential human exposure through bites, scratches and other direct contacts with bats, or as opportunistic assessment of sick or dead bats. The level of medical intervention and post exposure prophylaxis is largely determined on laboratory testing for antigen/virus as the demonstrable infection status of the in-contact bat. This study evaluates the comparative diagnostic performance of a lateral flow test, Anigen Rabies Ag detection rapid test (RDT), in pteropodid variant of ABLV infected bat brain tissues. The RDT demonstrated 100% agreement with the reference standard fluorescent antibody test on 43 clinical samples suggesting a potential application in rapid diagnosis of pteropodid variant of ABLV infection. A weighted Kappa value of 0.95 confirmed a high level of agreement between both tests. PMID- 30287780 TI - Identification of Safety-Related Opinion Leaders among Construction Workers: Evidence from Scaffolders of Metro Construction in Wuhan, China. AB - This study aimed to reveal opinion leaders who could impact their coworkers' safety-related performance in Chinese construction teams. Questionnaires were distributed to 586 scaffolders in Wuhan to understand their opinions about influencing their coworkers, serving as the foundation for a social network analysis to identify the potential opinion leaders among workers. A further controlled trial with the identified workers was conducted to select real opinion leaders by comparing their influence on others' safety-related behavior, followed by an association analysis to profile these opinion leaders. Two main sources of opinion leaders were identified: foremen and seasoned workers. Implementing interventions through opinion leaders resulted in better safety-related behavior performance. Furthermore, compared with education level, the association analysis results indicated that one's practical skills and familiarity with respondents was more important in the formulation of opinion leaders. This research introduces the concept of opinion leaders into construction safety and proposes an approach to identify and validate opinion leaders within a crew, thus providing a tool to improve behavior promotion on sites, as well as a new perspective for viewing interactions among workers. PMID- 30287779 TI - Effect of Collagen Hydrolysates from Silver Carp Skin (Hypophthalmichthys molitrix) on Osteoporosis in Chronologically Aged Mice: Increasing Bone Remodeling. AB - Osteoporosis is a common skeletal disorder in humans and gelatin hydrolysates from mammals have been reported to improve osteoporosis. In this study, 13-month old mice were used to evaluate the effects of collagen hydrolysates (CHs) from silver carp skin on osteoporosis. No significant differences were observed in mice body weight, spleen or thymus indices after daily intake of antioxidant collagen hydrolysates (ACH; 200 mg/kg body weight (bw) (LACH), 400 mg/kg bw (MACH), 800 mg/kg bw (HACH)), collagenase hydrolyzed collagen hydrolysates (CCH) or proline (400 mg/kg body weight) for eight weeks, respectively. ACH tended to improve bone mineral density, increase bone hydroxyproline content, enhance alkaline phosphatase (ALP) level and reduce tartrate-resistant acid phosphatase 5b (TRAP-5b) activity in serum, with significant differences observed between the MACH and model groups (p < 0.05). ACH exerted a better effect on osteoporosis than CCH at the identical dose, whereas proline had no significant effect on repairing osteoporosis compared to the model group. Western blotting results demonstrated that CHs mainly increased bone remodeling by stimulating the transforming growth factor beta1 (TGF-beta1)/Smad signaling pathway and improving the interaction between collagen and alpha2beta1 integrin. The results indicated that CHs from fish could be applied to alleviate osteoporosis or treat bone loss.

AB - Iron deficiency (ID) is usually treated with oral iron salts, but up to 50% of patients complain of gastrointestinal side effects, leading to reduced treatment compliance. Intravenous (IV) iron formulations are increasingly safer, but there is still a risk of infusion and hypersensitivity reactions and the need for a venous access and infusion monitoring. Sucrosomial(r) iron (SI) is an innovative oral iron formulation in which ferric pyrophosphate is protected by a phospholipid bilayer plus a sucrester matrix (sucrosome), which is absorbed through para-cellular and trans-cellular routes (M cells). This confers SI unique structural, physicochemical and pharmacokinetic characteristics, together with high iron bioavailability and excellent gastrointestinal tolerance. The analysis of available evidence supports oral SI iron as a valid option for ID treatment, which is more efficacious and better tolerated than oral iron salts. SI has also demonstrated similar effectiveness, with lower risks, in patients usually receiving IV iron (e.g., chronic kidney disease, cancer, bariatric surgery). Thus, oral SI emerges as a most valuable first option for treating ID, even more for subjects with intolerance to or inefficacy of iron salts. Moreover, SI should be also considered as an alternative to IV iron for initial and/or maintenance treatment in different patient populations.

AB - African cichlids display a remarkable assortment of jaw morphologies, pigmentation patterns, and mating behaviors. In addition to this previously documented diversity, recent studies have documented a rich diversity of sex chromosomes within these fishes. Here we review the known sex-determination network within vertebrates, and the extraordinary number of sex chromosomes systems segregating in African cichlids. We also propose a model for understanding the unusual number of sex chromosome systems within this clade. PMID- 30287782 TI - Cube-Rhombellane Related Structures: A Drug Perspective. AB - Rhombellanes represent a new class of structures, of which homeomorphs may be synthesized as real molecules. Cube-rhombellane is a double-shell structure, with vertices of degree 3 and 6, respectively. Several hypothetical structures/molecules were proposed and computed using molecular graph theory and coordination chemistry principles. Some geometries were optimized at the B3LYP/6 31G (d, p) level of theory, followed by harmonic vibrational frequency analysis at the same level of theory, single point data were collected in view of molecular stability evaluation. Some of the bioactive functionalized structures were also proposed and explored by molecular mechanics (MM)-based conformational analysis, to check their internal mobility. Drug-like properties of the proposed molecular structures were compared with some existing nano-molecules (fullerenes, nanotubes). ADME and other physico-chemical characteristics were computed using commercial software. Substructures of the proposed molecules, useful in a future synthesis, were provided by retro combinatorial synthesis (RECAP). Computational results obtained are promising regarding ADME properties, drug-likeness and nano properties. PMID- 30287784 TI - Genotype Fingerprints Enable Fast and Private Comparison of Genetic Testing Results for Research and Direct-to-Consumer Applications. AB - Genetic testing has expanded out of the research laboratory into medical practice and the direct-to-consumer market. Rapid analysis of the resulting genotype data now has a significant impact. We present a method for summarizing personal genotypes as 'genotype fingerprints' that meets these needs. Genotype fingerprints can be derived from any single nucleotide polymorphism-based assay, and remain comparable as chip designs evolve to higher marker densities. We demonstrate that these fingerprints support distinguishing types of relationships among closely related individuals and closely related individuals from individuals from the same background population, as well as high-throughput identification of identical genotypes, individuals in known background populations, and de novo separation of subpopulations within a large cohort through extremely rapid comparisons. Although fingerprints do not preserve anonymity, they provide a useful degree of privacy by summarizing a genotype while preventing reconstruction of individual marker states. Genotype fingerprints are therefore well-suited as a format for public aggregation of genetic information to support ancestry and relatedness determination without revealing personal health risk status. PMID- 30287783 TI - Chemotherapeutic Efficacy of Implantable Antineoplastic-Treatment Protocols in an Optimal Mouse Model for Human Ovarian Carcinoma Cell Targeting. AB - The present study aimed to design and develop a nanocomposite drug delivery system employing an antineoplastic-loaded antibody functionalized nanomicelle encapsulated within a Chitosan-Poly(vinylpyrrolidone)-Poly(N-isopropylacrylamide) (C-P-N) hydrogel to form an in situ forming implant (ISFI), responsive to temperature and pH for cancer cell-targeting following intraperitoneal implantation. The optimum nanomicelle formulation was surface-functionalized with anti-MUC 16 (antibody) for the targeted delivery of methotrexate to human ovarian carcinoma (NIH:OVCAR-5) cells in Athymic nude mice that expressed MUC16, as a preferential form of intraperitoneal ovarian cancer (OC) chemotherapy. The cross linked interpenetrating C-P-N hydrogel was synthesized for the preparation of an in situ-forming implant (ISFI). Subsequently, the ISFI was fabricated by encapsulating a nanocomposite comprising of anti-MUC16 (antibody) functionalized methotrexate (MTX)-loaded poly(N-isopropylacrylamide)-b-poly(aspartic acid) (PNIPAAm-b-PASP) nanomicelles (AF(MTX)NM's) within the cross-linked C-P-N hydrogel. This strategy enabled specificity and increased the residence time of the nanomicelles at tumor sites over a period exceeding one month, enhancing uptake of drugs and preventing recurrence and chemo-resistance. Chemotherapeutic efficacy was tested on the optimal ovarian tumor-bearing Athymic nude mouse model and the results demonstrated tumor regression including reduction in mouse weight and tumor size, as well as a significant (p < 0.05) reduction in mucin 16 levels in plasma and ascitic fluid, and improved survival of mice after treatment with the experimental anti-MUC16/CA125 antibody-bound nanotherapeutic implant drug delivery system (ISFI) (p < 0.05). The study also concluded that ISFI could potentially be considered an important immuno-chemotherapeutic agent that could be employed in human clinical trials of advanced, and/or recurring, metastatic epithelial ovarian cancer (EOC). The development of this ISFI may circumvent the treatment flaws experienced with conventional systemic therapies, effectively manage recurrent disease and ultimately prolong disease-free intervals in ovarian cancer patients. PMID- 30287785 TI - Deep Learning Cluster Structures for Management Decisions: The Digital CEO. AB - This paper presents a Deep Learning (DL) Cluster Structure for Management Decisions that emulates the way the brain learns and makes choices by combining different learning algorithms. The proposed model is based on the Random Neural Network (RNN) Reinforcement Learning for fast local decisions and Deep Learning for long-term memory. The Deep Learning Cluster Structure has been applied in the Cognitive Packet Network (CPN) for routing decisions based on Quality of Service (QoS) metrics (Delay, Loss and Bandwidth) and Cyber Security keys (User, Packet and Node) which includes a layer of DL management clusters (QoS, Cyber and CEO) that take the final routing decision based on the inputs from the DL QoS clusters and RNN Reinforcement Learning algorithm. The model has been validated under different network sizes and scenarios. The simulation results are promising; the presented DL Cluster management structure as a mechanism to transmit, learn and make packet routing decisions is a step closer to emulate the way the brain transmits information, learns the environment and takes decisions. PMID- 30287786 TI - Using Low-Cost Sensors to Develop a High Precision Lifting Controller Device for an Overhead Crane-Insights and Hypotheses from Prototyping a Heavy Industrial Internet Project. AB - The subject of this study was the product development project creating a new innovative proof-of-concept (POC) prototype device that could control a connected industrial overhead crane in order to perform automatic or semi-automatic high precision lifts within a limited time frame. The development work focused on innovating a new measuring concept, which was parallel to finding suitable sensors for the application. Furthermore, the project resulted in a closed loop control system with Industrial Internet connected sensors and a user interface for factory workers. The prototyping journey is depicted to illustrate the decisions made during the product development project to contribute to both the pragmatic and the process discussion in the field of Industrial Internet. The purpose of this research was to explore and generate hypotheses for how new applications should be developed for heavy industry connected devices. The research question is: what are the implications of applying agile product development methods, such as Wayfaring, to heavy industrial machinery and Industrial Internet -based problems? The methodologies used in this paper, in addition to developing the device, are case study research and hypotheses generated from case studies. The hypotheses generated include that it is also possible to prototype large size connected machinery with low-cost and in a short time, and investment decisions for heavy Industrial Internet products become easier with concrete data from proof-of-concept prototypes by creating knowledge about the investment risk and the value proposition. PMID- 30287787 TI - Gait Type Analysis Using Dynamic Bayesian Networks. AB - This paper focuses on gait abnormality type identification-specifically, recognizing antalgic gait. Through experimentation, we demonstrate that detecting an individual's gait type is a viable biometric that can be used along with other common biometrics for applications such as forensics. To classify gait, the gait data is represented by coordinates that reflect the body joint coordinates obtained using a Microsoft Kinect v2 system. Features such as cadence, stride length, and other various joint angles are extracted from the input data. Using approaches such as the dynamic Bayesian network, the obtained features are used to model as well as perform gait type classification. The proposed approach is compared with other classification techniques and experimental results reveal that it is capable of obtaining a 88.68% recognition rate. The results illustrate the potential of using a dynamic Bayesian network for gait abnormality classification. PMID- 30287788 TI - Time-Dependent Degradation of Polyphenols from Thermally-Processed Berries and Their In Vitro Antiproliferative Effects against Melanoma. AB - Polyphenols are natural occurring micronutrients that can protect plants from natural weathering and are also helpful to humans. These compounds are abundantly found in fruits or berries. Because of berry seasonal availability and also due to their rapid degradation, people have found multiple ways to preserve them. The most common options are freezing or making jams. Polyphenol stability, during processing is a continuous challenge for the food industry. There are also multiple published data providing that they are sensitive to light, pH or high temperature, vectors which are all present during jam preparation. In this context the aim of this study was to assess phytochemical composition and bioactive compounds degradation after jam preparation. We also monitored their degradation during storage time and their in vitro antiproliferative potential when tested on melanoma cells. The obtained results revealed that when processed and stored in time, the bioactive compounds from berries jams are degrading, but they still exert antioxidant and antiproliferative potential. Prior to LC-MS analysis, polyphenolic compounds were identified as: flavonoids (anthocyanins (ANT), flavonols (FLA)) and non-flavonoid (hydroxycinnamic acids (HCA) and hydroxybenzoic acids (HBA)). The most significant decrease was observed for HCA compared to other classes of compounds. This variation is expected due to differences in constituents and phenolic types among different analyzed berries. PMID- 30287789 TI - Changes in Pain and Nutritional Intake Modulate Ultra-Running Performance: A Case Report. AB - Ultra-endurance running provides numerous physiological, psychological, and nutritional challenges to the athlete and supporting practitioners. We describe the changes in physiological status, psychological condition, and nutritional intake over the course of two 100-mile running races, with differing outcomes: non-completion and completion. Athlete perception of pain, freshness, and motivation differed between events, independent of rating of perceived exertion. Our data suggest that the integration of multiple sensations (freshness, motivation, hunger, pain, and thirst) produce performance. Increases in carbohydrate feeding (+5 g.h-1) and protein intake (+0.3 g.kg-1) also likely contributed to successful completion of a 100-mile race, by reducing the fractional utilization of maximal oxygen uptake and satiating hunger, respectively. Nutritional data support the notion that the gut is a trainable, and critical organ with respect to ultra-endurance performance. Finally, we propose future research to investigate the rate at which peak feeding occurs throughout ultra-endurance events, as this may further serve to personalize sports nutrition strategies. PMID- 30287793 TI - Resonator Based Switching Technique between Ultra Wide Band (UWB) and Single/Dual Continuously Tunable-Notch Behaviors in UWB Radar for Wireless Vital Signs Monitoring. AB - This paper presents a novel resonator that can switch and create three important behaviors within the same antenna using miniaturized capacitors. The resonator was integrated into conventional Ultra-Wide Band (UWB) antenna to achieve UWB and Single/Dual continuously tunable-notch behaviors. The Single/Dual notched was continuously tuned to our desired frequency band by changing the value of the capacitors. The antenna designed and fabricated to validate these behaviors had a compact size of 24 * 30.5 mm2, including the ground plane. The radiation patterns were very clean due to the placement of the proposed resonator in the special ground plane. Moreover, the presented novel resonator and switching technique was compared with the recently proposed resonators and their switching techniques. The prototype for the antenna was also developed in order to validate its performance in wireless vital signs monitoring. The presented miniaturized resonator based antenna was utilized for tumor sensing and simulations were provided in this regard. Moreover, the deployment of the proposed resonator based UWB antenna sensor in Pipeline Integrity Monitoring system was also investigated and discussed. PMID- 30287791 TI - Identification of a Novel PPAR-gamma Agonist through a Scaffold Tuning Approach. AB - Peroxisome proliferator-activated receptors (PPARs) are important targets in metabolic diseases including obesity, metabolic syndrome, diabetes, and non alcoholic fatty liver disease. Recently, they have been highlighted as attractive targets for the treatment of cardiovascular diseases and chronic myeloid leukemia. The PPAR agonist structure is consists of a polar head, a hydrophobic tail, and a linker. Each part interacts with PPARs through hydrogen bonds or hydrophobic interactions to stabilize target protein conformation, thus increasing its activity. Acidic head is essential for PPAR agonist activity. The aromatic linker plays an important role in making hydrophobic interactions with PPAR as well as adjusting the head-to-tail distance and conformation of the whole molecule. By tuning the scaffold of compound, the whole molecule could fit into the ligand-binding domain to achieve proper binding mode. We modified indol-3 ylacetic acid scaffold to (indol-1-ylmethyl)benzoic acid, whereas 2,4 dichloroanilide was fixed as the hydrophobic tail. We designed, synthesized, and assayed the in vitro activity of novel indole compounds with (indol-1 ylmethyl)benzoic acid scaffold. Compound 12 was a more potent PPAR-gamma agonist than pioglitazone and our previous hit compound. Molecular docking studies may suggest the binding between compound 12 and PPAR-gamma, rationalizing its high activity. PMID- 30287792 TI - Conservation of k-mer Composition and Correlation Contribution between Introns and Intergenic Regions of Animalia Genomes. AB - In this study, we pairwise-compared multiple genome regions, including genes, exons, coding DNA sequences (CDS), introns, and intergenic regions of 39 Animalia genomes, including Deuterostomia (27 species) and Protostomia (12 species), by applying established k-mer-based (alignment-free) comparison methods. We found strong correlations between the sequence structure of introns and intergenic regions, individual organisms, and within wider phylogenetical ranges, indicating the conservation of certain structures over the full range of analyzed organisms. We analyzed these sequence structures by quantifying the contribution of different sets of DNA words to the average correlation value by decomposing the correlation coefficients with respect to these word sets. We found that the conserved structures within introns, intergenic regions, and between the two were mainly a result of conserved tandem repeats with repeat units <= 2 bp (e.g., (AT)n), while other conserved sequence structures, such as those found between exons and CDS, were dominated by tandem repeats with repeat unit sizes of 3 bp in length and more complex DNA word patterns. We conclude that the conservation between intron and intergenic regions indicates a shared function of these sequence structures. Also, the similar differences in conserved structures with known origin, especially to the conservation between exons and CDS resulting from DNA codons, indicate that k-mer composition-based functional properties of introns and intergenic regions may differ from those of exons and CDS. PMID- 30287790 TI - Novel Functions of Death-Associated Protein Kinases through Mitogen-Activated Protein Kinase-Related Signals. AB - Death associated protein kinase (DAPK) is a calcium/calmodulin-regulated serine/threonine kinase; its main function is to regulate cell death. DAPK family proteins consist of DAPK1, DAPK2, DAPK3, DAPK-related apoptosis-inducing protein kinases (DRAK)-1 and DRAK-2. In this review, we discuss the roles and regulatory mechanisms of DAPK family members and their relevance to diseases. Furthermore, a special focus is given to several reports describing cross-talks between DAPKs and mitogen-activated protein kinases (MAPK) family members in various pathologies. We also discuss small molecule inhibitors of DAPKs and their potential as therapeutic targets against human diseases. PMID- 30287794 TI - First-principles Investigations of Magnetic Semiconductors: An example of Transition Metal Decorated Two-dimensional SnS Monolayer. AB - The absence of magnetic moments in pristine two-dimensional (2D) semiconducting materials has attracted many research interests. Transition-metal (TM) decoration has been found to be an effective strategy to introduce magnetic moments in non magnetic 2D semiconductors. However, the stability of TM atoms modified 2D semiconductors has not been well explored. Here, taking 2D Tin (II) sulfide (SnS) monolayer as a prototype, we explored the stability of magnetic semiconductors through this method. In our studies, all possible configurations of TM decoration have been considered, namely, adsorption on the intact surface, S vacancy, and Sn vacancy. Based on the energy gain and electronic analysis, our results revealed that most of the TM atoms will form a cluster, and only several TM atoms can be effectively doped into the SnS monolayer. Furthermore, the band calculations showed that only Mn substitution will give rise to a magnetic semiconductor. Thus, the reported results here provide some hidden information for further realization of the magnetic semiconductors and serve as a paradigm to prepare 2D magnetic semiconductors. PMID- 30287795 TI - Application of Ultrasound in Food Science and Technology: A Perspective. AB - Ultrasound is composed of mechanical sound waves that originate from molecular movements that oscillate in a propagation medium. The waves have a very high frequency, equal to approximately 20 kHz, are divided into two categories (i.e., low-intensity and high-intensity waves) and cannot be perceived by the human ear. Nature has created the first ultrasound applications. Bats use ultrasound to navigate in the dark, and many cetaceans use echolocation to detect prey or obstacles using ultrasound produced by their vocal system. Ultrasound is commonly associated with the biomedical field. Today, ultrasound-based methods and equipment are available to detect organs, motion, tumour masses, and pre/post natal handicaps, and for kidney stone removal, physiotherapy, and aesthetic cures. However, ultrasound has found multiple applications in many other fields as well. In particular, ultrasound has recently been used in the food industry to develop various effective and reliable food processing applications. Therefore, this review summarizes the major applications of ultrasound in the food industry. The most common applications in the food industry include cell destruction and extraction of intracellular material. Depending on its intensity, ultrasound is used for the activation or deactivation of enzymes, mixing and homogenization, emulsification, dispersion, preservation, stabilization, dissolution and crystallization, hydrogenation, tenderization of meat, ripening, ageing and oxidation, and as an adjuvant for solid-liquid extraction for maceration to accelerate and to improve the extraction of active ingredients from different matrices, as well as the degassing and atomization of food preparations. PMID- 30287796 TI - Probing the Occurrence of Soluble Oligomers through Amyloid Aggregation Scaling Laws. AB - Drug discovery frequently relies on the kinetic analysis of physicochemical reactions that are at the origin of the disease state. Amyloid fibril formation has been extensively investigated in relation to prevalent and rare neurodegenerative diseases, but thus far no therapeutic solution has directly arisen from this knowledge. Other aggregation pathways producing smaller, hard-to detect soluble oligomers are increasingly appointed as the main reason for cell toxicity and cell-to-cell transmissibility. Here we show that amyloid fibrillation kinetics can be used to unveil the protein oligomerization state. This is illustrated for human insulin and ataxin-3, two model proteins for which the amyloidogenic and oligomeric pathways are well characterized. Aggregation curves measured by the standard thioflavin-T (ThT) fluorescence assay are shown to reflect the relative composition of protein monomers and soluble oligomers measured by nuclear magnetic resonance (NMR) for human insulin, and by dynamic light scattering (DLS) for ataxin-3. Unconventional scaling laws of kinetic measurables were explained using a single set of model parameters consisting of two rate constants, and in the case of ataxin-3, an additional order-of-reaction. The same fitted parameters were used in a discretized population balance that adequately describes time-course measurements of fibril size distributions. Our results provide the opportunity to study oligomeric targets using simple, high throughput compatible, biophysical assays. PMID- 30287798 TI - Oral Modified Release Multiple-Unit Particulate Systems: Compressed Pellets, Microparticles and Nanoparticles. AB - Oral modified-release multiparticulate dosage forms, which are also referred to as oral multiple-unit particulate systems, are becoming increasingly popular for oral drug delivery applications. The compaction of polymer-coated multiparticulates into tablets to produce a sustained-release dosage form is preferred over hard gelatin capsules. Moreover, multiparticulate tablets are a promising solution to chronic conditions, patients' adherence, and swallowing difficulties if incorporated into orodispersible matrices. Nonetheless, the compaction of multiparticulates often damages the functional polymer coat, which results in a rapid release of the drug substance and the subsequent loss of sustained-release properties. This review brings to the forefront key formulation variables that are likely to influence the compaction of coated multiparticulates into sustained-release tablets. It focusses on the tabletting of coated drug loaded pellets, microparticles, and nanoparticles with a designated section on each. Furthermore, it explores the various approaches that are used to evaluate the compaction behaviour of particulate systems. PMID- 30287797 TI - Machine Learning Approaches for Protein-Protein Interaction Hot Spot Prediction: Progress and Comparative Assessment. AB - Hot spots are the subset of interface residues that account for most of the binding free energy, and they play essential roles in the stability of protein binding. Effectively identifying which specific interface residues of protein protein complexes form the hot spots is critical for understanding the principles of protein interactions, and it has broad application prospects in protein design and drug development. Experimental methods like alanine scanning mutagenesis are labor-intensive and time-consuming. At present, the experimentally measured hot spots are very limited. Hence, the use of computational approaches to predicting hot spots is becoming increasingly important. Here, we describe the basic concepts and recent advances of machine learning applications in inferring the protein-protein interaction hot spots, and assess the performance of widely used features, machine learning algorithms, and existing state-of-the-art approaches. We also discuss the challenges and future directions in the prediction of hot spots. PMID- 30287800 TI - Bioinspired Honokiol Analogs and Their Evaluation for Activity on the Norepinephrine Transporter. AB - In traditional Asian medicinal systems, preparations of the root and stem bark of Magnolia species are widely used to treat anxiety and other nervous disturbances. The biphenyl-type neolignans honokiol and magnolol are the main constituents of Magnolia bark extracts. In the central nervous system, Magnolia bark preparations that contain honokiol are thought to primarily interact with gamma-aminobutyric acid A (GABAA) receptors. However, stress responses inherently involve the noradrenergic system, which has not been investigated in the pharmacological mechanism of honokiol. We present here interactions of honokiol and other synthesized biphenyl-type neolignans and diphenylmethane analogs with the norepinephrine transporter (NET), which is responsible for the synaptic clearance of norepinephrine and the target of many anxiolytics. Of the synthesized compounds, 16 are new chemical entities, which are fully characterized. The 52 compounds tested show mild, non-potent interactions with NET (IC50 > 100 uM). It is thus likely that the observed anxiolytic effects of, e.g., Magnolia preparations, are not due to direct interaction with the noradrenergic system. PMID- 30287799 TI - The Role of Hydrogen Peroxide in Redox-Dependent Signaling: Homeostatic and Pathological Responses in Mammalian Cells. AB - Hydrogen peroxide (H2O2) is an important metabolite involved in most of the redox metabolism reactions and processes of the cells. H2O2 is recognized as one of the main molecules in the sensing, modulation and signaling of redox metabolism, and it is acting as a second messenger together with hydrogen sulfide (H2S) and nitric oxide (NO). These second messengers activate in turn a cascade of downstream proteins via specific oxidations leading to a metabolic response of the cell. This metabolic response can determine proliferation, survival or death of the cell depending on which downstream pathways (homeostatic, pathological, or protective) have been activated. The cells have several sources of H2O2 and cellular systems strictly control its concentration in different subcellular compartments. This review summarizes research on the role played by H2O2 in signaling pathways of eukaryotic cells and how this signaling leads to homeostatic or pathological responses. PMID- 30287803 TI - Primary Intrahepatic Squamous Cell Carcinoma with Histological Collision of Adenocarcinoma and Squamous Cell Carcinoma: A Case Report. AB - BACKGROUND Cholangiocarcinoma is a rare, aggressive biliary tract malignancy. On histopathology, most tumors are adenocarcinomas, while squamous cell carcinoma of the biliary tract is extremely rare. CASE REPORT An 82-year-old male was admitted due to the detection of a space-occupying lesion at S6 of the liver. On abdominal dynamic computed tomography, there was an irregular mass with inhomogeneous density associated with mild delayed enhancement in the tumor's peripheral zone, measuring approximately 22*25 mm, at S6, with secondary dilated biliary ducts of B6. Endoscopic retrograde cholangiopancreatography showed a severe stricture at B6. Brush cytology of B6 was positive for both adenocarcinoma and squamous cell carcinoma. Furthermore, mucous brushing cytology of the papilla of Vater was also positive for adenocarcinoma. Finally, the preoperative diagnosis of primary intrahepatic cholangiocarcinoma, combined with a cancer of the papilla of Vater, was made. The patient underwent both extended right lobectomy and pancreaticoduodenectomy. Histological examination showed that the majority (>99%) of this liver tumor was composed of keratinizing squamous cell carcinoma. CONCLUSIONS Squamous cell carcinoma of the biliary tree is very rare, since the majority of biliary tree tumors are adenocarcinomas. Cholangiocarcinoma containing a squamous cell component has a poor prognosis. To the best of our knowledge, this is the first case report of a primary intrahepatic squamous cell carcinoma that presented as a solid tumor showing clear histological collision between adenocarcinoma and squamous cell carcinoma and was successfully treated with hepatic resection and achieved disease-free survival of more than one year. PMID- 30287801 TI - Response of Cellular Innate Immunity to Cnidarian Pore-Forming Toxins. AB - A group of stable, water-soluble and membrane-bound proteins constitute the pore forming toxins (PFTs) in cnidarians. They interact with membranes to physically alter the membrane structure and permeability, resulting in the formation of pores. These lesions on the plasma membrane causes an imbalance of cellular ionic gradients, resulting in swelling of the cell and eventually its rupture. Of all cnidarian PFTs, actinoporins are by far the best studied subgroup with established knowledge of their molecular structure and their mode of pore-forming action. However, the current view of necrotic action by actinoporins may not be the only mechanism that induces cell death since there is increasing evidence showing that pore-forming toxins can induce either necrosis or apoptosis in a cell-type, receptor and dose-dependent manner. In this review, we focus on the response of the cellular immune system to the cnidarian pore-forming toxins and the signaling pathways that might be involved in these cellular responses. Since PFTs represent potential candidates for targeted toxin therapy for the treatment of numerous cancers, we also address the challenge to overcoming the immunogenicity of these toxins when used as therapeutics. PMID- 30287804 TI - Utilization of Standard Criteria Donor and Expanded Criteria Donor Kidneys After Kidney Allocation System Implementation. AB - BACKGROUND Implementation of the Kidney Allocation System (KAS) changed how kidneys are allocated and the information on which organ utilization decisions are based. We aimed to evaluate how KAS implementation changed kidney utilization and recipient outcomes. MATERIAL AND METHODS Using the United Network for Organ Sharing database, we identified recipients of kidney transplants from donors with kidney donor profile index (KDPI) of 61-90% in the 5-years pre- and 18-months post-KAS implementation and examined patient and graft survival and donor kidney discard rates based on standard criteria donor (SCD) or expanded criteria donor (ECD) status. RESULTS The proportion of ECD kidneys was unchanged pre- versus post-KAS. Post-KAS, SCD kidneys were less likely to be transplanted into young recipients while ECD kidneys were more likely to be transplanted. SCD kidneys in the post-KAS period conferred a 1.42 (95% CI: 1.18-1.73) times higher adjusted mortality and 2% lower 1-year survival (94.2% vs. 96.2%, P<0.001) but had unchanged graft failure compared to pre-KAS. For ECD kidneys, there was no difference in mortality or graft survival. The discard rate increased after KAS for both SCD and ECD kidneys (P<0.05) but was not different between SCD and ECD kidneys for any KDPI group. CONCLUSIONS After KAS implementation, patient survival for recipients of SCD kidneys was significantly worse. PMID- 30287802 TI - Pediatric Spinal Ependymomas. AB - BACKGROUND The aim of this study was to assess the clinical and radiological outcomes of surgical treatment for primary spinal ependymoma in children. MATERIAL AND METHODS Medical records of 46 primary spinal ependymoma patients who underwent surgery in BRSHH hospital during a 12-year period from 2004 to 2015 were retrospectively reviewed. All pediatric patients (patient age <18 years) were selected as the core sample used for this study. RESULTS This series included 1 female and 2 male patients between the ages of 9 and 17 years with mean age 13.3+/-3.9 years. The mean preoperative course was 9.1+/-10.5 months. The most common location was the lumbar spinal cord (n=2). The most common presenting symptoms was lower-limb weakness and numbness. Two tumors were located intradural-intramedullary and 1 was located intradural-extramedullary. Gross total resection (GTR) was achieved in 2 patients, and a near-total resection was performed in 1 patient. No adjuvant treatment was received. The mean follow-up duration was 51.3+/-37.6 (17-98) months. No complications were recorded. Functional assessment of all patients by the latest follow-up evaluation showed good progress even though the patient is not fully recovered. At 6.3 years after the first operation, 1 patient presented with drop-seeding metastasis. No patients had neurofibromatosis type 2. CONCLUSIONS Laminoplasty and intraoperative neurophysiological monitorization are essential in surgical treatment of pediatric spinal ependymomas. GTR and recovery in pediatric spinal ependymoma are more likely than in adults. Despite the GTR, the risk of drop metastasis remains. Therefore, close clinical and radiological follow-up is recommended. PMID- 30287805 TI - [What works in selective prevention of alcohol and cannabis use among vulnerable young people?] AB - OBJECTIVE: Selective prevention tackle vulnerable factors associated to problem consumption and social exclusion. There are few effective programs in our context. Study aims were first to identify selective programs of alcohol and cannabis consumption for youths between 16-21, and second, to review intervention, evaluation and effects quality. METHODS: MEDLINE, PubMed, Google academics, EDDRA, SAMHSA, PBE and recommendations of PND were reviewed. Inclusion criteria were: 1) English/ Spanish programs, 2) publications <10 years, 3) target population 16- 21 years old 4) alcohol/ cannabis psicoeducational or socioeducational programs, 5) selective or selective/indicated programs and 6) evaluated programs. The description and quality of the intervention, its evaluation methods, and the presentation of its effects were assessed according to 20 criteria emerged from different recommendations. RESULTS: Fourteen programs followed the inclusion criteria, 10 of followed minimum quality intervention and evaluation criteria, however only 5 shown significant effects. Effective programs tackled negative emotions associated to consumption, promoted skills to cope it and reduce frequency of alcohol consumption, but rarely cannabis consumption. CONCLUSIONS: There are few selective prevention programs, and different studies shown that they have intervention or evaluation weaknesses, but mostly about program effects. The most effective are: PreVenture, The Climate Schools: Alcohol and Cannabis Course, Programa TND, Keepin' it REAL and Weekend is coming. PMID- 30287806 TI - Genome-wide association study identifies glutamate ionotropic receptor GRIA4 as a risk gene for comorbid nicotine dependence and major depression. AB - Smoking and major depression frequently co-occur, at least in part due to shared genetic risk. However, the nature of the shared genetic basis is poorly understood. To detect genetic risk variants for comorbid nicotine dependence (ND) and major depression (MD), we conducted genome-wide association study (GWAS) in two samples of African-American participants (Yale-Penn 1 and 2) using linear mixed model, followed by meta-analysis. 3724 nicotine-exposed subjects were analyzed: 2596 from Yale-Penn-1 and 1128 from Yale-Penn-2. Continuous measures (Fagerstrom Test for Nicotine Dependence (FTND) scores and DSM-IV MD criteria) rather than disorder status were used to maximize the power of the GWAS. Genotypes were ascertained using the Illumina HumanOmni1-Quad array (Yale-Penn-1 sample) or the Illumina HumanCore Exome array (Yale-Penn-2 sample), followed by imputation based on the 1000 Genomes reference panel. An intronic variant at the GRIA4 locus, rs68081839, was significantly associated with ND-MD comorbidity (beta = 0.69 [95% CI, 0.43-0.89], P = 1.53 * 10-8). GRIA4 encodes an AMPA sensitive glutamate receptor that mediates fast excitatory synaptic transmission and neuroplasticity. Conditional analyses revealed that the association was explained jointly by both traits. Enrichment analysis showed that the top risk genes and genes co-expressed with GRIA4 are enriched in cell adhesion, calcium ion binding, and synapses. They also have enriched expression in the brain and they have been implicated in the risk for other neuropsychiatric disorders. Further research is needed to determine the replicability of these findings and to identify the biological mechanisms through which genetic risk for each condition is conveyed. PMID- 30287807 TI - The Use of International Classification of Diseases Codes to Identify Patients with Pancreatitis: A Systematic Review and Meta-analysis of Diagnostic Accuracy Studies. AB - BACKGROUND: Hospital discharge codes are increasingly used in gastroenterology research, but their accuracy in the setting of acute pancreatitis (AP) and chronic pancreatitis (CP), one of the most frequent digestive diseases, has never been assessed systematically. The aim was to conduct a systematic literature review and determine accuracy of diagnostic codes for AP and CP, as well as the effect of covariates. METHODS: Three databases (Pubmed, EMBASE and Scopus) were searched by two independent reviewers for relevant studies that used International Classification of Disease (ICD) codes. Summary estimates of sensitivity, specificity and positive predictive value were obtained from bivariate random-effects regression models. Sensitivity and subgroup analyses according to recurrence of AP and age of the study population were performed. RESULTS: A total of 24 cohorts encompassing 18,106 patients were included. The pooled estimates of sensitivity and specificity of ICD codes for AP were 0.85 and 0.96, respectively. The pooled estimates of sensitivity and specificity of ICD codes for CP were 0.75 and 0.94, respectively. The positive predictive value of ICD codes was 0.71 for either AP or CP. It increased to 0.78 when applied to incident episode of AP only. The positive predictive value decreased to 0.68 when the ICD codes were applied to paediatric patients. CONCLUSION: Nearly three out of ten patients are misidentified as having either AP or CP with the indiscriminate use of ICD codes. Limiting the use of ICD codes to adult patients with incident episode of AP may improve identification of patients with pancreatitis in administrative databases.

AB - Van der Waals heterostructures stacked from different two-dimensional materials offer a unique platform for addressing many fundamental physics and construction of advanced devices. Twist angle between the two individual layers plays a crucial role in tuning the heterostructure properties. Here we report the experimental investigation of the twist angle-dependent conductivities in MoS2/graphene van der Waals heterojunctions. We found that the vertical conductivity of the heterojunction can be tuned by ~5 times under different twist configurations, and the highest/lowest conductivity occurs at a twist angle of 0 degrees /30 degrees . Density functional theory simulations suggest that this conductivity change originates from the transmission coefficient difference in the heterojunctions with different twist angles. Our work provides a guidance in using the MoS2/graphene heterojunction for electronics, especially on reducing the contact resistance in MoS2 devices as well as other TMDCs devices contacted by graphene. PMID- 30287808 TI - Androgen deprivation promotes neuroendocrine differentiation and angiogenesis through CREB-EZH2-TSP1 pathway in prostate cancers. AB - The incidence of aggressive neuroendocrine prostate cancers (NEPC) related to androgen-deprivation therapy (ADT) is rising. NEPC is still poorly understood, such as its neuroendocrine differentiation (NED) and angiogenic phenotypes. Here we reveal that NED and angiogenesis are molecularly connected through EZH2 (enhancer of zeste homolog 2). NED and angiogenesis are both regulated by ADT activated CREB (cAMP response element-binding protein) that in turn enhances EZH2 activity. We also uncover anti-angiogenic factor TSP1 (thrombospondin-1, THBS1) as a direct target of EZH2 epigenetic repression. TSP1 is downregulated in advanced prostate cancer patient samples and negatively correlates with NE markers and EZH2. Furthermore, castration activates the CREB/EZH2 axis, concordantly affecting TSP1, angiogenesis and NE phenotypes in tumor xenografts. Notably, repressing CREB inhibits the CREB/EZH2 axis, tumor growth, NED, and angiogenesis in vivo. Taken together, we elucidate a new critical pathway, consisting of CREB/EZH2/TSP1, underlying ADT-enhanced NED and angiogenesis during prostate cancer progression. PMID- 30287810 TI - CLOCK and BMAL1 stabilize and activate RHOA to promote F-actin formation in cancer cells. AB - Circadian genes control most of the physiological functions in cancer cells, including cell proliferation, migration, and invasion. The CLOCK and BMAL1 complex plays a central role in circadian rhythms. Previous studies have shown that circadian genes may act as oncogenes or tumor-suppressor genes. In addition, F-actin, regulated by RHOA, has been shown to participate in tumor progression. However, the roles of the CLOCK and BMAL1 genes in the regulation of tumor progression via the RHOA-ROCK-CFL pathway remain largely unclear. Here we first indicate that the rearrangement of F-actin is regulated by CLOCK and BMAL1. We found that CLOCK and BMAL1 can upregulate RHOA expression by inhibiting CUL3 mediated ubiquitination and activate RHOA by reducing the interaction between RHOA and RhoGDI. Consequently, CLOCK and BMAL1 control the expression of the components of the RHOA-ROCK-CFL pathway, which alters the dynamics of F-actin/G actin turnover and promotes cancer cell proliferation, migration, and invasion. In conclusion, our research proposes a novel insight into the role of CLOCK and BMAL1 in tumor cells. PMID- 30287811 TI - Sex-specific correlation of IGFBP-2 and IGFBP-3 with vitamin D status in adults with obesity: a cross-sectional serum proteomics study. AB - OBJECTIVE: Subjects with low vitamin D levels are at risk of cardiometabolic disease. The aim of this study was to identify novel serological markers linking vitamin D status with cardiometabolic profile in non-diabetic adults with obesity. METHODS: For the discovery phase, we used quantitative serum proteomics in sex-matched, age-matched and BMI-matched subjects with obesity [BMI: 25-35 kg/m2] and low [25(OH)D < 50 nmol/L] vs. high vitamin D status [25(OH)D > 50 nmol/L] (n = 16). For the validation phase, we performed ELISA in a larger cohort with similar characteristics (n = 179). RESULTS: We identified 423 and 549 differentially expressed proteins in the high vs. low vitamin D groups of the male and female cohorts, respectively. The small molecule biochemistry protein networks and the glycolysis|gluconeogenesis pathway were significantly enriched in the DEPs of both sexes. As surrogate markers to these processes, the insulin like growth factor binding protein -2 (IGFBP-2) was upregulated in males, whereas IGFBP-3 was upregulated in females from the high Vitamin D status. This sex-specific trend was confirmed using Luminex ELISA to an independent but clinically analogous cohort of males (n = 84, p = 0.002) and females (n = 95, p = 0.03). CONCLUSIONS: The high Vitamin D status correlated with the serological upregulation of IGFBP-2 in males and IGFBP-3 in females with obesity and may constitute surrogate markers of risk reduction of cardiometabolic disease. PMID- 30287813 TI - Sustainable scalable synthesis of sulfide nanocrystals at low cost with an ionic liquid sulfur precursor. AB - Increasing the sustainability of nanocrystals is crucial to their application and the protection of the environment. Sulfur precursors for their synthesis are commonly obtained through multiple steps from H2S, only to be converted back to H2S during the synthesis of the nanocrystals. This convoluted process requires energy, reduces yields, increases waste and auxiliaries, and complicates recycling. Using H2S directly could drastically improve sustainability, but is prevented by toxicity and handling. We here show that H2S is stabilized by reaction with oleylamine (the most common and versatile ligand in nanoparticle synthesis) to form an ionic liquid precursor that addresses all major principles of green chemistry: it is made in one exothermic step, it leaves the reaction yielding a safer product and allowing the separate recycling of the precursors, and it produces high quality nanocrystals with high yields (sulfur yield > 70%) and concentrations (90 g L-1) in ambient conditions. PMID- 30287812 TI - DNA damage sensitivity of SWI/SNF-deficient cells depends on TFIIH subunit p62/GTF2H1. AB - Mutations in SWI/SNF genes are amongst the most common across all human cancers, but efficient therapeutic approaches that exploit vulnerabilities caused by SWI/SNF mutations are currently lacking. Here, we show that the SWI/SNF ATPases BRM/SMARCA2 and BRG1/SMARCA4 promote the expression of p62/GTF2H1, a core subunit of the transcription factor IIH (TFIIH) complex. Inactivation of either ATPase subunit downregulates GTF2H1 and therefore compromises TFIIH stability and function in transcription and nucleotide excision repair (NER). We also demonstrate that cells with permanent BRM or BRG1 depletion have the ability to restore GTF2H1 expression. As a consequence, the sensitivity of SWI/SNF-deficient cells to DNA damage induced by UV irradiation and cisplatin treatment depends on GTF2H1 levels. Together, our results expose GTF2H1 as a potential novel predictive marker of platinum drug sensitivity in SWI/SNF-deficient cancer cells. PMID- 30287814 TI - Recommendations for acquisition, interpretation and reporting of whole body low dose CT in patients with multiple myeloma and other plasma cell disorders: a report of the IMWG Bone Working Group. AB - Whole Body Low Dose CT (WBLDCT) has important advantages as a first-line imaging modality for bone disease assessment in patients with plasma cell disorders and has been included in the 2014 International Myeloma Working Group (IMWG) criteria for multiple myeloma (MM) definition. Nevertheless, standardization guidelines for the optimal use of WBLDCT in MM patients are still lacking, preventing its more widespread use, both in daily practice and clinical trials. The aim of this report by the Bone Group of the IMWG is to provide practical recommendations for the acquisition, interpretation and reporting of WBLDCT in patients with multiple myeloma and other plasma cell disorders. PMID- 30287815 TI - Selective prebiotic conversion of pyrimidine and purine anhydronucleosides into Watson-Crick base-pairing arabino-furanosyl nucleosides in water. AB - Prebiotic nucleotide synthesis is crucial to understanding the origins of life on Earth. There are numerous candidates for life's first nucleic acid, however, currently no prebiotic method to selectively and concurrently synthesise the canonical Watson-Crick base-pairing pyrimidine (C, U) and purine (A, G) nucleosides exists for any genetic polymer. Here, we demonstrate the divergent prebiotic synthesis of arabinonucleic acid (ANA) nucleosides. The complete set of canonical nucleosides is delivered from one reaction sequence, with regiospecific glycosidation and complete furanosyl selectivity. We observe photochemical 8 mercaptopurine reduction is efficient for the canonical purines (A, G), but not the non-canonical purine inosine (I). Our results demonstrate that synthesis of ANA may have been facile under conditions that comply with plausible geochemical environments on early Earth and, given that ANA is capable of encoding RNA/DNA compatible information and evolving to yield catalytic ANA-zymes, ANA may have played a critical role during the origins of life. PMID- 30287816 TI - A ballistic graphene superconducting microwave circuit. AB - Josephson junctions (JJ) are a fundamental component of microwave quantum circuits, such as tunable cavities, qubits, and parametric amplifiers. Recently developed encapsulated graphene JJs, with supercurrents extending over micron distance scales, have exciting potential applications as a new building block for quantum circuits. Despite this, the microwave performance of this technology has not been explored. Here, we demonstrate a microwave circuit based on a ballistic graphene JJ embedded in a superconducting cavity. We directly observe a gate tunable Josephson inductance through the resonance frequency of the device and, using a detailed RF model, we extract this inductance quantitatively. We also observe the microwave losses of the device, and translate this into sub-gap resistances of the junction at MUeV energy scales, not accessible in DC measurements. The microwave performance we observe here suggests that graphene Josephson junctions are a feasible platform for implementing coherent quantum circuits. PMID- 30287818 TI - Infected Pancreatic Necrosis due to Multidrug-Resistant Organisms and Persistent Organ failure Predict Mortality in Acute Pancreatitis. AB - BACKGROUND: Organ failure determines outcome in acute pancreatitis (AP). It is controversial if infected pancreatic necrosis (IPN) is also an independent determinant of mortality. We hypothesized that the predictors of mortality in AP might have changed with advances in management and consequent decline in mortality over the past decades. Our objective was to study the predictors of mortality in patients with AP. METHODS: Consecutive patients with a first episode of AP hospitalized from January 2015 to December 2016 were included in an observational study. Patients with IPN were treated with a conservative first approach followed by intervention. Necrosectomy, if required, was delayed beyond 4 weeks and done primarily employing minimally invasive techniques. The primary outcome measure was independent predictors of in-hospital mortality. RESULTS: Of 209 patients with AP, 81 (39%) had persistent organ failure (OF) and 108 (52%) developed IPN. Overall, 46/209 (22%) patients died. Independent predictors of mortality were OF (odds ratio [OR]19; 95% CI: 6.1-58.8), and IPN due to infection with multidrug resistant (MDR) organisms (OR: 8.4; 95% CI:3.1-22.5). Infected pancreatic necrosis by itself was not found to be a significant predictor of mortality (OR 2; 95% CI: 0.4-9.5). CONCLUSION: Persistent OF and complicated IPN due to MDR infection were independent predictors of mortality in patients with AP. Renewed efforts to prevent MDR infection with antibiotic stewardship and strategies for early control of sepsis are urgently required. PMID- 30287817 TI - Atomic cobalt as an efficient electrocatalyst in sulfur cathodes for superior room-temperature sodium-sulfur batteries. AB - The low-cost room-temperature sodium-sulfur battery system is arousing extensive interest owing to its promise for large-scale applications. Although significant efforts have been made, resolving low sulfur reaction activity and severe polysulfide dissolution remains challenging. Here, a sulfur host comprised of atomic cobalt-decorated hollow carbon nanospheres is synthesized to enhance sulfur reactivity and to electrocatalytically reduce polysulfide into the final product, sodium sulfide. The constructed sulfur cathode delivers an initial reversible capacity of 1081 mA h g-1 with 64.7% sulfur utilization rate; significantly, the cell retained a high reversible capacity of 508 mA h g-1 at 100 mA g-1 after 600 cycles. An excellent rate capability is achieved with an average capacity of 220.3 mA h g-1 at the high current density of 5 A g-1. Moreover, the electrocatalytic effects of atomic cobalt are clearly evidenced by operando Raman spectroscopy, synchrotron X-ray diffraction, and density functional theory. PMID- 30287819 TI - Improvement and extension of anti-EGFR targeting in breast cancer therapy by integration with the Avidin-Nucleic-Acid-Nano-Assemblies. AB - Nowadays, personalized cancer therapy relies on small molecules, monoclonal antibodies, or antibody-drug conjugates (ADC). Many nanoparticle (NP)-based drug delivery systems are also actively investigated, but their advantage over ADCs has not been demonstrated yet. Here, using the Avidin-Nucleic-Acid-Nano Assemblies (ANANAS), a class of polyavidins multifuctionalizable with stoichiometric control, we compare quantitatively anti-EGFR antibody(cetuximab) targeted NPs to the corresponding ADC. We show that ANANAS tethering of cetuximab promotes a more efficient EGFR-dependent vesicle-mediated internalization. Cetuximab-guided ANANAS carrying doxorubicin are more cytotoxic in vitro and much more potent in vivo than the corresponding ADC, leading to 43% tumor reduction at low drug dosage (0.56 mg/kg). Advantage of cetuximab-guided ANANAS with respect to the ADC goes beyond the increase in drug-to-antibody ratio. Even if further studies are needed, we propose that NP tethering could expand application of the anti-EGFR antibody to a wider number of cancer patients including the KRAS mutated ones, currently suffering from poor prognosis. PMID- 30287820 TI - Observation of Coulomb gap in the quantum spin Hall candidate single-layer 1T' WTe2. AB - The two-dimensional topological insulators host a full gap in the bulk band, induced by spin-orbit coupling (SOC) effect, together with the topologically protected gapless edge states. However, it is usually challenging to suppress the bulk conductance and thus to realize the quantum spin Hall (QSH) effect. In this study, we find a mechanism to effectively suppress the bulk conductance. By using the quasiparticle interference technique with scanning tunneling spectroscopy, we demonstrate that the QSH candidate single-layer 1T'-WTe2 has a semimetal bulk band structure with no full SOC-induced gap. Surprisingly, in this two dimensional system, we find the electron-electron interactions open a Coulomb gap which is always pinned at the Fermi energy (EF). The opening of the Coulomb gap can efficiently diminish the bulk state at the EF and supports the observation of the quantized conduction of topological edge states. PMID- 30287821 TI - Resolving the mechanisms of hygroscopic growth and cloud condensation nuclei activity for organic particulate matter. AB - Hygroscopic growth and cloud condensation nuclei activation are key processes for accurately modeling the climate impacts of organic particulate matter. Nevertheless, the microphysical mechanisms of these processes remain unresolved. Here we report complex thermodynamic behaviors, including humidity-dependent hygroscopicity, diameter-dependent cloud condensation nuclei activity, and liquid liquid phase separation in the laboratory for biogenically derived secondary organic material representative of similar atmospheric organic particulate matter. These behaviors can be explained by the non-ideal mixing of water with hydrophobic and hydrophilic organic components. The non-ideality-driven liquid liquid phase separation further enhances water uptake and induces lowered surface tension at high relative humidity, which result in a lower barrier to cloud condensation nuclei activation. By comparison, secondary organic material representing anthropogenic sources does not exhibit complex thermodynamic behavior. The combined results highlight the importance of detailed thermodynamic representations of the hygroscopicity and cloud condensation nuclei activity in models of the Earth's climate system. PMID- 30287823 TI - Germline pathogenic variants of 11 breast cancer genes in 7,051 Japanese patients and 11,241 controls. AB - Pathogenic variants in highly penetrant genes are useful for the diagnosis, therapy, and surveillance for hereditary breast cancer. Large-scale studies are needed to inform future testing and variant classification processes in Japanese. We performed a case-control association study for variants in coding regions of 11 hereditary breast cancer genes in 7051 unselected breast cancer patients and 11,241 female controls of Japanese ancestry. Here, we identify 244 germline pathogenic variants. Pathogenic variants are found in 5.7% of patients, ranging from 15% in women diagnosed <40 years to 3.2% in patients >=80 years, with BRCA1/2, explaining two-thirds of pathogenic variants identified at all ages. BRCA1/2, PALB2, and TP53 are significant causative genes. Patients with pathogenic variants in BRCA1/2 or PTEN have significantly younger age at diagnosis. In conclusion, BRCA1/2, PALB2, and TP53 are the major hereditary breast cancer genes, irrespective of age at diagnosis, in Japanese women. PMID- 30287824 TI - Extracts of Polypore Mushroom Mycelia Reduce Viruses in Honey Bees. AB - Waves of highly infectious viruses sweeping through global honey bee populations have contributed to recent declines in honey bee health. Bees have been observed foraging on mushroom mycelium, suggesting that they may be deriving medicinal or nutritional value from fungi. Fungi are known to produce a wide array of chemicals with antimicrobial activity, including compounds active against bacteria, other fungi, or viruses. We tested extracts from the mycelium of multiple polypore fungal species known to have antiviral properties. Extracts from amadou (Fomes) and reishi (Ganoderma) fungi reduced the levels of honey bee deformed wing virus (DWV) and Lake Sinai virus (LSV) in a dose-dependent manner. In field trials, colonies fed Ganoderma resinaceum extract exhibited a 79-fold reduction in DWV and a 45,000-fold reduction in LSV compared to control colonies. These findings indicate honey bees may gain health benefits from fungi and their antimicrobial compounds. PMID- 30287822 TI - High-throughput in vivo mapping of RNA accessible interfaces to identify functional sRNA binding sites. AB - Herein we introduce a high-throughput method, INTERFACE, to reveal the capacity of contiguous RNA nucleotides to establish in vivo intermolecular RNA interactions for the purpose of functional characterization of intracellular RNA. INTERFACE enables simultaneous accessibility interrogation of an unlimited number of regions by coupling regional hybridization detection to transcription elongation outputs measurable by RNA-seq. We profile over 900 RNA interfaces in 71 validated, but largely mechanistically under-characterized, Escherichia coli sRNAs in the presence and absence of a global regulator, Hfq, and find that two thirds of tested sRNAs feature Hfq-dependent regions. Further, we identify in vivo hybridization patterns that hallmark functional regions to uncover mRNA targets. In this way, we biochemically validate 25 mRNA targets, many of which are not captured by typically tested, top-ranked computational predictions. We additionally discover direct mRNA binding activity within the GlmY terminator, highlighting the information value of high-throughput RNA accessibility data. PMID- 30287825 TI - Stepwise oxygenation of the Paleozoic atmosphere. AB - Oxygen is essential for animal life, and while geochemical proxies have been instrumental in determining the broad evolutionary history of oxygen on Earth, much of our insight into Phanerozoic oxygen comes from biogeochemical modelling. The GEOCARBSULF model utilizes carbon and sulphur isotope records to produce the most detailed history of Phanerozoic atmospheric O2 currently available. However, its predictions for the Paleozoic disagree with geochemical proxies, and with non isotope modelling. Here we show that GEOCARBSULF oversimplifies the geochemistry of sulphur isotope fractionation, returning unrealistic values for the O2 sourced from pyrite burial when oxygen is low. We rebuild the model from first principles, utilizing an improved numerical scheme, the latest carbon isotope data, and we replace the sulphur cycle equations in line with forwards modelling approaches. Our new model, GEOCARBSULFOR, produces a revised, highly-detailed prediction for Phanerozoic O2 that is consistent with available proxy data, and independently supports a Paleozoic Oxygenation Event, which likely contributed to the observed radiation of complex, diverse fauna at this time. PMID- 30287826 TI - Multi-Band Sensing for Dielectric Property of Chemicals Using Metamaterial Integrated Microfluidic Sensor. AB - The growth of the chemical industry has brought tremendous challenges to chemical sensing technology. Chemical sensors based on metamaterials have great potential because of their label-free and non-destructive characteristics. However, metamaterials applied in chemical sensing have mainly been investigated from the measurement of sample concentration or the determination of the dielectric properties at a fixed frequency. Here we present a metamaterial integrated microfluidic (MIM) sensor for the multi-band sensing for dielectric property of chemicals, which is promising for the identification of chemicals. The MIM sensor mainly consists of multiple pair of high sensitive symmetrical double split-ring resonators (DSRRs) and meandering microfluidic channels with a capacity of only 4 MUL. A dielectric model has been innovatively established and experimentally verified to accurately estimate the complex permittivity and thus realize the multi-band sensing of dielectric property of chemicals. With the increase in the number of resonators in the sensor, a dielectric spectrum like curve could be obtained for more detailed dielectric information. This work delivers a miniaturized, reusable, label-free and non-destructive metamaterial-microfluidic solution and paves a way of the multi-band sensing for dielectric property of chemicals. PMID- 30287827 TI - Effect of central lesions on a spinal circuit facilitating human wrist flexors. AB - A putative spinal circuit with convergent inputs facilitating human wrist flexors has been recently described. This study investigated how central nervous system lesions may affect this pathway. We measured the flexor carpi radialis H-reflex conditioned with stimulation above motor threshold to the extensor carpi radialis at different intervals in fifteen patients with stroke and nine with spinal cord injury. Measurements after stroke revealed a prolonged facilitation of the H reflex, which replaced the later suppression seen in healthy subjects at longer intervals (30-60 ms). Measurements in patients with incomplete spinal cord injury at cervical level revealed heterogeneous responses. Results from patients with stroke could represent either an excessive facilitation or a loss of inhibition, which may reflect the development of spasticity. Spinal cord injury results possibly reflect damage to the segmental interneuron pathways. We report a straightforward method to assess changes to spinal circuits controlling wrist flexors after central nervous system lesion.

PMID- 30287828 TI - Altered cerebral benzodiazepine receptor binding in post-traumatic stress disorder. AB - Agonists of the gamma-aminobutyric acid (GABA) type A benzodiazepine (BZD) receptor exert anxiolytic effects in anxiety disorders, raising the possibility that altered GABA-ergic function may play a role in the pathophysiology of anxiety disorders, such as post-traumatic stress disorder (PTSD). However, few neuroimaging studies have assessed the function or binding potential of the central GABAA BZD receptor system in PTSD. Therefore, our aim was to compare the BZD receptor binding potential between PTSD patients and healthy controls. Twelve medication-free participants with a current diagnosis of PTSD and 15 matched healthy controls underwent positron emission tomography (PET) imaging using [11C] flumazenil. Structural magnetic resonance imaging (MRI) scans were obtained and co-registered to the PET images to permit co-location of neuroanatomical structures in the lower resolution PET image data. Compared to healthy controls, PTSD patients exhibited increased BZD binding in the caudal anterior cingulate cortex and precuneus (p's < 0.05). Severity of PTSD symptoms positively correlated with BZD binding in the left mid- and anterior insular cortices. This study extends previous findings by suggesting that central BZD receptor system involvement in PTSD includes portions of the default mode and salience networks, along with insular regions that support interoception and autonomic arousal. PMID- 30287830 TI - Two-photon polymerisation 3D printed freeform micro-optics for optical coherence tomography fibre probes. AB - Miniaturised optical coherence tomography (OCT) fibre-optic probes have enabled high-resolution cross-sectional imaging deep within the body. However, existing OCT fibre-optic probe fabrication methods cannot generate miniaturised freeform optics, which limits our ability to fabricate probes with both complex optical function and dimensions comparable to the optical fibre diameter. Recently, major advances in two-photon direct laser writing have enabled 3D printing of arbitrary three-dimensional micro/nanostructures with a surface roughness acceptable for optical applications. Here, we demonstrate the feasibility of 3D printing of OCT probes. We evaluate the capability of this method based on a series of characterisation experiments. We report fabrication of a micro-optic containing an off-axis paraboloidal total internal reflecting surface, its integration as part of a common-path OCT probe, and demonstrate proof-of-principle imaging of biological samples. PMID- 30287831 TI - Analysis of the mechanisms regulating the expression of isoprenoid biosynthesis genes in hydroponically-grown Nicotiana benthamiana plants using virus-induced gene silencing. AB - Secondary metabolites in plants play important roles in defence against biotic and abiotic stresses. Although the biosynthesis pathways of secondary metabolites have been extensively studied, the regulatory mechanism of gene expression involved in these pathways remains poorly understood. In this study, we develop a virus-induced gene silencing (VIGS) system that enables a rapid analysis of the regulatory mechanism of genes involved in the biosynthesis of isoprenoids, one of the largest groups in secondary metabolites, using hydroponically-grown Nicotiana benthamiana. Using VIGS, we successfully reduced the transcript levels of 3 hydroxy-3-methylglutaryl-CoA reductase 1 (HMGR1), cycloartenol synthase 1 (CAS1), sterol side chain reductase 2 (SSR2) and S-adenosyl-L-Met-dependent C-24 sterol methyltransferase 1 (SMT1) in leaf, stem and root tissues in approximately 2 weeks. We identified novel feedback and feed-forward regulation of isoprenoid biosynthesis genes when CAS1, which encodes a key enzyme involved in the biosynthesis of sterols and steroidal glycoalkaloids, was down-regulated. Furthermore, the regulation of these genes differed among different tissues. These results demonstrate that our system can rapidly analyse the regulatory mechanisms involved in the biosynthesis of secondary metabolites. PMID- 30287832 TI - The endless visuomotor calibration of reach-to-grasp actions. AB - It is reasonable to assume that when we grasp an object we carry out the movement based only on the currently available sensory information. Unfortunately, our senses are often prone to err. Here, we show that the visuomotor system exploits the mismatch between the predicted and sensory outcomes of the immediately preceding action (sensory prediction error) to attain a degree of robustness against the fallibility of our perceptual processes. Participants performed reach to-grasp movements toward objects presented at eye level at various distances. Grip aperture was affected by the object distance, even though both visual feedback of the hand and haptic feedback were provided. Crucially, grip aperture as well as the trajectory of the hand were systematically influenced also by the immediately preceding action. These results are well predicted by a model that modifies an internal state of the visuomotor system by adjusting the visuomotor mapping based on the sensory prediction errors. In sum, the visuomotor system appears to be in a constant fine-tuning process which makes the generation and control of grasping movements more resistant to interferences caused by our perceptual errors. PMID- 30287833 TI - Ultra-low-field magneto-elastocaloric cooling in a multiferroic composite device. AB - The advent of caloric materials for magnetocaloric, electrocaloric, and elastocaloric cooling is changing the landscape of solid state cooling technologies with potentials for high-efficiency and environmentally friendly residential and commercial cooling and heat-pumping applications. Given that caloric materials are ferroic materials that undergo first (or second) order phase transitions near room temperature, they open up intriguing possibilities for multiferroic devices with hitherto unexplored functionalities coupling their thermal properties with different fields (magnetic, electric, and stress) through composite configurations. Here we demonstrate a magneto-elastocaloric effect with ultra-low magnetic field (0.16 T) in a compact geometry to generate a cooling temperature change as large as 4 K using a magnetostriction/superelastic alloy composite. Such composite systems can be used to circumvent shortcomings of existing technologies such as the need for high-stress actuation mechanism for elastocaloric materials and the high magnetic field requirement of magnetocaloric materials, while enabling new applications such as compact remote cooling devices. PMID- 30287834 TI - Changing environments during the Middle-Upper Palaeolithic transition in the eastern Cantabrian Region (Spain): direct evidence from stable isotope studies on ungulate bones. AB - Environmental change has been proposed as a factor that contributed to the extinction of the Neanderthals in Europe during MIS3. Currently, the different local environmental conditions experienced at the time when Anatomically Modern Humans (AMH) met Neanderthals are not well known. In the Western Pyrenees, particularly, in the eastern end of the Cantabrian coast of the Iberian Peninsula, extensive evidence of Neanderthal and subsequent AMH activity exists, making it an ideal area in which to explore the palaeoenvironments experienced and resources exploited by both human species during the Middle to Upper Palaeolithic transition. Red deer and horse were analysed using bone collagen stable isotope analysis to reconstruct environmental conditions across the transition. A shift in the ecological niche of horses after the Mousterian demonstrates a change in environment, towards more open vegetation, linked to wider climatic change. In the Mousterian, Aurignacian and Gravettian, high inter individual nitrogen ranges were observed in both herbivores. This could indicate that these individuals were procured from areas isotopically different in nitrogen. Differences in sulphur values between sites suggest some variability in the hunting locations exploited, reflecting the human use of different parts of the landscape. An alternative and complementary explanation proposed is that there were climatic fluctuations within the time of formation of these archaeological levels, as observed in pollen, marine and ice cores.

PMID- 30287836 TI - Earthquake-induced structural deformations enhance long-term solute fluxes from active volcanic systems. AB - Evidence for relationships between seismotectonic activity and dissolved weathering fluxes remains limited. Motivated by the occurrence of new springs emerging after the 2016 Kumamoto earthquake and supported by historical groundwater data, this study focuses on the long-term effect of near-surface structural deformation on the contribution of deep, highly saline fluids to the solute fluxes from the Aso caldera, Kyushu, Japan. Available hydrologic and structural data suggest that concentrated, over-pressured groundwaters migrate to the surface when new hydraulic pathways open during seismic deformation. These new springs have a hydrochemical fingerprint (including deltaDH2O, delta18OH2O, delta7Li, delta11B, delta18OSO4, and delta34SSO4) indistinguishable from long established confined groundwater that likely reflects a mixture of infiltrated meteoric water with high-sulfate hydrothermal fluids. A comparison of historical hydrochemistry data and patterns of past seismicity suggests that discharge of deep fluids is associated with similar deformation structures to those observed during the Kumamoto earthquake, and that seismic activity plays an important role over historic timescales in delivering the majority of the solutes to the caldera outlet, sustaining fluxes that are amongst the world's highest. This upwelling mechanism might be relevant for other systems too, and could contribute to the over-proportional share of active volcanic areas in global weathering fluxes.

AB - Converging evidence demonstrates that emotion processing from facial expressions continues to improve throughout childhood and part of adolescence. Here we investigated whether this is also the case for emotions conveyed by non linguistic vocal expressions, another key aspect of social interactions. We tested 225 children and adolescents (age 5-17) and 30 adults in a forced-choice labeling task using vocal bursts expressing four basic emotions (anger, fear, happiness and sadness). Mixed-model logistic regressions revealed a small but highly significant change with age, mainly driven by changes in the ability to identify anger and fear. Adult-level of performance was reached between 14 and 15 years of age. Also, across ages, female participants obtained better scores than male participants, with no significant interaction between age and sex effects. These results expand the findings showing that affective prosody understanding improves during childhood; they document, for the first time, continued improvement in vocal affect recognition from early childhood to mid- adolescence, a pivotal period for social maturation.

AB - The calcium/calmodulin-dependent protein kinases (CAMKKs) are upstream activators of CAMK1 and CAMK4 signalling and have important functions in neural development, maintenance and signalling, as well as in other aspects of biology such as Ca2+ signalling in the cardiovascular system. To support the development of specific inhibitors of CAMKKs we have determined the crystal structure of CAMKK1 with two ATP-competitive inhibitors. The structures reveal small but exploitable differences between CAMKK1 and CAMKK2, despite the high sequence identity, which could be used in the generation of specific inhibitors. Screening of a kinase inhibitor library revealed molecules that bind potently to CAMKK1. Isothermal titration calorimetry revealed that the most potent inhibitors had binding energies largely dependent on favourable enthalpy. Together, the data provide a foundation for future inhibitor development activities. PMID- 30287838 TI - Systematic expression alteration analysis of master reprogramming factor OCT4 and its three pseudogenes in human cancer and their prognostic outcomes. AB - OCT4 is a master transcription factor that regulates the pluripotency of pluripotent stem cells and cancer stem cells along with other factors, including SOX2, KLF4, and C-MYC. Three different transcripts, OCT4A, OCT4B, and OCT4B1, are known to be generated by alternative splicing and eight OCT4 pseudogenes have been found in the human genome. Among them, we examined OCT4 and three pseudogenes (POU5F1P1, POU5F1P3, and POU5F1P4) because of their high expression possibility in cancer. In addition, previous studies indicated that OCT4 expression is augmented in cervical cancer and associated with poor prognosis, whereas OCT4 is down-regulated and correlated with good clinical outcomes in breast cancer. Because of these conflicting reports, we systematically evaluated whether expression of OCT4 and its pseudogenes can serve as oncogenic markers in various human cancers using the Oncomine database. Moreover, copy number alterations and mutations in OCT4 gene and its pseudogenes were analyzed using cBioPortal and the relationship between expression of OCT4 and pseudogenes and survival probability of cancer patients were explored using Kaplan-Meier plotter, OncoLnc, PROGgeneV2, and PrognoScan databases. Multivariate survival analysis was further conducted to determine the risk of the expression of the occurrence of OCT4 and its pseudogenes on certain cancer types using data from the Kaplan-Meier plotter. Overall, an association between expression of OCT4 and pseudogenes and cancer prognosis were established, which may serve as a therapeutic target for various human cancers. PMID- 30287840 TI - Procaspase-3-activating compound 1 stabilizes hypoxia-inducible factor 1alpha and induces DNA damage by sequestering ferrous iron. AB - Procaspase-3-activating compound 1 (PAC-1) induces procaspase-3 activation via zinc chelation. However, whether PAC-1 employs other mechanisms remains unknown. Here we systematically screened for potent PAC-1 targets using 29 enhanced green fluorescent protein-labeled reporter cell lines and identified hypoxia-inducible factor 1alpha (HIF1alpha) and RAD51 pathways as PAC-1 targets. These results were verified in HepG2 cells and two other cancer cell lines. Mechanistically, PAC-1 specifically blocked HIF1alpha hydroxylation and upregulated HIF1alpha target genes. In addition, DNA damage, G1/S cell cycle arrest, and the inhibition of DNA synthesis were induced following PAC-1 administration. Interestingly, by using ferrozine-iron sequestration and iron titration assays, we uncovered the iron sequestering capacity of PAC-1. Additionally, the expression levels of iron shortage-related genes were also increased in PAC-1-treated cells, and iron (II) supplementation reversed all of the observed cellular responses. Thus, our results indicate that PAC-1 induces HIF1alpha stabilization and DNA damage by sequestering ferrous iron. PMID- 30287842 TI - Design, Construction and Validation of an Electrical Impedance Probe with Contact Force and Temperature Sensors Suitable for in-vivo Measurements. AB - Bioimpedance spectroscopy measurements can be used for tissue characterization. These measurements can be performed in soft tissues by direct contact of a non invasive probe consisting of two or four electrodes. The amount of force applied by users can be quite different, and the measurements can vary as a result. To compensate for this, we have built an electrical impedance probe (diameter 3.2 mm) with fibre optic contact-force and temperature sensors built in it. The different sensors of the probe were tested individually. The errors in magnitude and phase angle of the probe are <0.9% and <4 degrees , respectively, for a 0.9% NaCl solution. The linear dynamic range of the force sensor was from 0 to 100 grams. An ex-vivo experiment on a section of proximal colon from a guinea-pig was performed. Twenty bioimpedance measurements were taken in a frequency range of 5 kHz to 1 MHz, while simultaneously recording the force applied. For an increase in contact pressure applied to tissue from 0 to 15.4 kPa, the maximum change in resistivity was 33% at 5 kHz and the minimum was 6.6% at 142 kHz. The probe is small enough to be introduced via the instrument port of an endoscope. PMID- 30287841 TI - Genetic inhibition of an ATP synthase subunit extends lifespan in C. elegans. AB - Mild inhibition of mitochondrial respiration leads to longevity. Disruption of mitochondrial respiratory components extends lifespan in Caenorhabditis elegans, but the effects appear to be complex and the underlying mechanism for lifespan regulation by mitochondrial respiratory genes is still not fully understood. Here, we investigated the role of Y82E9BR.3, a worm homolog of the ATP synthase subunit C, in modulating longevity in C. elegans. We found that the Y82E9BR.3 protein is localized in mitochondria and expressed in various tissues throughout development. RNAi knockdown of Y82E9BR.3 extends lifespan, decreases the accumulation of lipofuscin, and affects various physiological processes, including development delay, reproduction impairment and slow behavior. Further tissue-specific RNAi analysis showed that the intestine is a crucial organ for the longevity effects conferred by Y82E9BR.3 RNAi. Moreover, we demonstrated that lifespan extension by Y82E9BR.3 RNAi is associated with reduced mitochondrial function, as well as the suppression of complex I activity in mitochondria. Unexpectedly, Y82E9BR.3 RNAi knock down did not influence the whole-worm ATP level. Our findings first reveal the crucial role of Y82E9BR.3 in mitochondrial function and the underlying mechanism of how Y82E9BR.3 regulates lifespan in C. elegans. PMID- 30287843 TI - A handheld platform for target protein detection and quantification using disposable nanopore strips. AB - Accessible point-of-care technologies that can provide immunoassay and molecular modalities could dramatically enhance diagnostics, particularly for infectious disease control in low-resource settings. Solid-state nanopores are simple and durable sensors with low-energy instrumentation requirements. While nanopore sensors have demonstrated efficacy for nucleic acid targets, selective detection and quantification of target proteins from sample background has not been demonstrated. We present a simple approach for electronic detection and quantification of target proteins that combines novel biomolecular engineering methods, a portable reader device and disposable nanopore test strips. The target of interest can be varied by swapping the binding domain on our engineered detection reagent, which eficiently binds in the bulk-phase to the target and subsequently generates a unique signature when passing through the pore. We show modularity of the detection reagent for two HIV antibodies, TNFalpha and tetanus toxin as targets. A saliva swab-to-result is demonstrated for clinically relevant HIV antibody levels (0.4-20 mg/liter) in under 60 seconds. While other strip-like assays are qualitative, the presented method is quantitative and sets the stage for simultaneous immunoassay and molecular diagnostic functionality within a single portable platform. PMID- 30287844 TI - A-to-I RNA editing enzyme ADAR2 regulates light-induced circadian phase-shift. AB - In mammals, the central circadian clock is located in the suprachiasmatic nucleus (SCN) of the hypothalamus and it orchestrates peripheral clocks in the whole body to organize physiological and behavioral rhythms. Light-induced phase-shift of the SCN clock enables synchronization of the circadian clock system with 24-h environmental light/dark cycle. We previously found that adenosine deaminase acting on RNA 2 (Adar2), an A-to-I RNA editing enzyme catalyzing rhythmic A-to-I RNA editing, governs a wide range of mRNA rhythms in the mouse liver and regulates the circadian behavior. In brain, ADAR2-mediated A-to-I RNA editing was reported to occur in various transcripts encoding ion channels and neurotransmitter receptors, which could influence neuronal function of the SCN. Here we show that ADAR2 plays a crucial role for light-induced phase-shift of the circadian clock. Intriguingly, exposure of Adar2-knockout mice to a light pulse at late night caused an aberrant phase-advance of the locomotor rhythms. By monitoring the bioluminescence rhythms of the mutant SCN slices, we found that a phase-advance induced by treatment with pituitary adenylyl cyclase-activating polypeptide (PACAP) was markedly attenuated. The present study suggests that A-to I RNA editing in the SCN regulates a proper phase response to light in the mouse circadian system. PMID- 30287845 TI - A Next-Generation Sequencing-Based Platform for Quantitative Detection of Hepatitis B Virus Pre-S Mutants in Plasma of Hepatocellular Carcinoma Patients. AB - Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death worldwide. Early diagnosis and treatment of HCC remain a key goal for improving patient survival. Chronic hepatitis B virus (HBV) infection is a major risk factor for HCC development. Pre-S mutants harboring deletions in HBV large surface antigen have been well demonstrated as HBV oncoproteins that dysregulate multiple signaling pathways in hepatocytes, leading to HCC formation. The presence of pre-S mutants in plasma represents important predictive and prognostic markers for HCC in patients with chronic HBV infection. However, the method to detect pre-S mutants remains to be optimized. In this study, we developed a platform, based on the next-generation sequencing (NGS) technology, for detection of pre-S mutants in plasma of HBV-related HCC patients. Compared to the current TA cloning-based analysis, the NGS-based analysis could detect pre-S deletion quantitatively, and the detection rate was significantly more sensitive in 49 plasma analyzed (McNemar's paired proportion test, P value < 0.0001; simple kappa coefficient, kappa = 0.29 (95% CI, 0.12 to 0.46)). Our data suggest that the NGS-based platform may hold a promise for improving the clinical application of pre-S mutants in serving as predictive and prognostic markers for HBV-related HCC. PMID- 30287846 TI - Drivers of within-field spatial and temporal variability of crop yield across the US Midwest. AB - Not all areas of a farmer's field are equal; some always produce more relative to the rest of the field, others always less, while still other areas fluctuate in their production capacity from one year to the next, depending on the interaction between climate, soil, topography and management. Understanding why the yield in certain portions of a field has a high variability over time-we call these areas unstable-is of paramount importance both from an economic and an environmental point of view, as it is through the better management of these areas that we can improve yields or reduce input costs and environmental impact. In this research, we analyzed data from 338 fields cultivated with maize, soybean, wheat and cotton in the US Midwest to understand how topographic attributes and rain affect yield stability over time. In addition to this high resolution yield monitor dataset, we used publicly available data on topography, rain and soil information to test the hypothesis that within-field areas characterized by a low topographic wetness index (proxy for areas with probability of lower water content) always perform poorly (low and stable yield) compared to the rest of the field because they are drier, and that areas of a field characterized by a mid-high wetness index (high and stable yield) always perform well relative to rest of the field because they have greater water availability to plants. The relative performance of areas of a field with a very high wetness index (e.g. depressions) strongly depends on rain patterns because they may be waterlogged in wet years, yielding less than the rest of the field, or wetter during dry years, yielding more than the rest of the field. We present three different observations from this dataset to support our hypothesis. First, we show that the average topographic wetness index in the different stability zones is lower in low and stable yield areas, high in high and stable yield areas and even higher in unstable yield areas (p < 0.05). Second, we show that in dry years (low precipitation at plant emergence or in July), unstable zones perform relatively better compared to the rest of the field. Third, we show that temporal yield variability is positively correlated (p < 0.05) with the probability of observing gleying processes associated with waterlogging for part of the year. These findings shed light on mechanisms underlying temporal variability of yield and can help guide management solutions to increase profit and improve environmental quality. PMID- 30287847 TI - Comparative synaptosome imaging: a semi-quantitative method to obtain copy numbers for synaptic and neuronal proteins. AB - Protein copy numbers can be measured by biochemical methods ranging from quantitative Western Blotting to several mass spectrometry approaches. Such methods only provide average copy numbers, obtained over large cell numbers. However, copy number estimates for single cells or single organelles could be obtained by combining biochemical characterizations with an imaging approach. We performed this here for synaptic proteins, in a protocol that we termed comparative synaptosome imaging for semi-quantitative copy numbers (CosiQuant). In brief, in CosiQuant we immunostain in parallel biochemically-characterized synaptosomes, for which we have already determined the average protein copy numbers, and the samples of interest (such as neuronal cultures). We then derive the copy numbers in the samples of interest by comparing the immunofluorescence intensities. We measured the intensities not only in arbitrary fluorescence units, but also as numbers of antibodies per synaptosome, for a large number of targets. This implies that other groups can immediately apply CosiQuant for these targets, by simply estimating the number of antibodies per structure of interest. CosiQuant should therefore be a useful addition to the growing set of imaging techniques for synaptic neuroscience. PMID- 30287848 TI - Experimental evidence of selective inattention in reputation-based cooperation. AB - Reputation-based cooperation is often observed in modern society. People gain several types of information by assessing others. Among these, the most important information is the actions of people and those of their recipients. However, almost all studies assume that people consider all of the information they receive. This assumption is extreme, and people engaging in reputation-based cooperation may not pay attention to some information, i.e., they may display selective inattention. We demonstrate that subjects' decision-making in relation to cooperative action depends on the content of the information they receive about their recipients. Our results show that subjects either consider or ignore information depending on the content of that information. When their recipients had cooperated previously, subjects cooperated without considering the information they received. When the recipients had played before with those who had bad reputations, subjects did not use that information, regardless of whether it was disclosed proactively. In other cases, subjects considered information on both the previous actions of recipients and those of the recipients' own recipients. We found that subjects did not always use the information to make decisions, although they willingly received information about their recipients. This supports the proposition that selective inattention occurs in reputation based cooperation. PMID- 30287849 TI - Computational Analysis of topological indices of two Boron Nanotubes. AB - There has been a recent debate that boron nanotubes can outperform carbon nanotubes on many grounds. The most stable boron nanotubes are made of a hexagonal lattice with an extra atom added to some of the hexagons called ?-boron nanotubes. Closed forms of M-polynomial of nanotubes produce closed forms of many degree-based topological indices which are numerical parameters of the structure and determine physico-chemical properties of the concerned nanotubes. In this article, we compute and analyze many topological indices of ?-boron nanotubes correlating with the size of structure of these tubes through the use of M polynomial. More importantly we make a graph-theoretic comparison of indices of two types of boron nanotubes namely triangular boron and ?-boron nanotubes. PMID- 30287850 TI - A subtype of cancer-associated fibroblasts with lower expression of alpha-smooth muscle actin suppresses stemness through BMP4 in oral carcinoma. AB - Cancer-associated fibroblasts (CAFs) demonstrate the characteristics of myofibroblast differentiation by often expressing the ultrastructure of alpha smooth muscle actin (alphaSMA). However, heterogeneity among cancer-associated fibroblasts (CAFs), with respect to alphaSMA expression, has been demonstrated in several clinical studies of oral cancer. Like normal stem cells, stem-like cancer cells (SLCCs) are also regulated extrinsically by its microenvironment; therefore, we postulated that the heterogeneous oral-CAFs would differently regulate oral-SLCCs. Using transcriptomics, we clearly demonstrated that the gene expression differences between oral tumor-derived CAFs were indeed the molecular basis of heterogeneity. This also grouped these CAFs in two distinct clusters, which were named as C1 and C2. Interestingly, the oral-CAFs belonging to C1 or C2 clusters showed low or high alphaSMA-score, respectively. Our data with tumor tissues and in vitro co-culture experiments interestingly demonstrated a negative correlation between alphaSMA-score and cell proliferation, whereas, the frequency of oral-SLCCs was significantly positively correlated with alphaSMA-score. The oral-CAF-subtype with lower score for alphaSMA (C1-type CAFs) was more supportive for cell proliferation but suppressive for the self-renewal growth of oral-SLCCs. Further, we found the determining role of BMP4 in C1-type CAFs-mediated suppression of self-renewal of oral-SLCCs. Overall, we have discovered an unexplored interaction between CAFs with lower-alphaSMA expression and SLCCs in oral tumors and provided the first evidence about the involvement of CAF expressed BMP4 in regulation of self-renewal of oral-SLCCs. PMID- 30287851 TI - Cell-based chemical fingerprinting identifies telomeres and lamin A as modifiers of DNA damage response in cancer cells. AB - Telomere maintenance by telomerase activity supports the infinite growth of cancer cells. MST-312, a synthetic telomerase inhibitor, gradually shortens telomeres at non-acute lethal doses and eventually induces senescence and apoptosis of telomerase-positive cancer cells. Here we report that MST-312 at higher doses works as a dual inhibitor of telomerase and DNA topoisomerase II and exhibits acute anti-proliferative effects on cancer cells and xenografted tumours in vivo. Our cell-based chemical fingerprinting approach revealed that cancer cells with shorter telomeres and lower expression of lamin A, a nuclear architectural protein, exhibited higher sensitivity to the acute deleterious effects of MST-312, accompanied by formation of telomere dysfunction-induced foci and DNA double-strand breaks. Telomere elongation and lamin A overexpression attenuated telomeric and non-telomeric DNA damage, respectively, and both conferred resistance to apoptosis induced by MST-312 and other DNA damaging anticancer agents. These observations suggest that sufficient pools of telomeres and a nuclear lamina component contribute to the cellular robustness against DNA damage induced by therapeutic treatment in human cancer cells. PMID- 30287852 TI - Increased spatial and temporal autocorrelation of temperature under climate change. AB - Understanding spatiotemporal variation in environmental conditions is important to determine how climate change will impact ecological communities. The spatial and temporal autocorrelation of temperature can have strong impacts on community structure and persistence by increasing the duration and the magnitude of unfavorable conditions in sink populations and disrupting spatial rescue effects by synchronizing spatially segregated populations. Although increases in spatial and temporal autocorrelation of temperature have been documented in historical data, little is known about how climate change will impact these trends. We examined daily air temperature data from 21 General Circulation Models under the business-as-usual carbon emission scenario to quantify patterns of spatial and temporal autocorrelation between 1871 and 2099. Although both spatial and temporal autocorrelation increased over time, there was significant regional variation in the temporal autocorrelation trends. Additionally, we found a consistent breakpoint in the relationship between spatial autocorrelation and time around the year 2030, indicating an acceleration in the rate of increase of the spatial autocorrelation over the second half of the 21st century. Overall, our results suggest that ecological populations might experience elevated extinction risk under climate change because increased spatial and temporal autocorrelation of temperature is expected to erode both spatial and temporal refugia. PMID- 30287853 TI - Calcineurin B homologous protein 3 binds with high affinity to the CHP binding domain of the human sodium/proton exchanger NHE1. AB - The Na+/H+ exchanger NHE1 is critical for cell vitality as it controls intracellular pH and cell volume. Its functionality is influenced by calcineurin B homologous proteins (CHPs). The human isoform CHP3 is important for transport of NHE1 to the plasma membrane and for its activity. Here, we characterized the binding interaction of human CHP3 with the regulatory domain of NHE1. The exact binding site of CHP3 was previously debated. CHP3 as well as both regions of NHE1 in question were produced and purified. CHP3 specifically formed stable complexes with the CHP-binding region (CBD) of NHE1 (residues 503-545) in size-exclusion chromatography (SEC), but not with the C-terminal region (CTD, residues 633-815). CTD was functional as shown by Ca2+-dependent binding of calmodulin in SEC analysis. CHP3 bound with high affinity to CBD with an equilibrium dissociation constant (KD) of 56 nM determined by microscale thermophoresis. The high affinity was substantiated by isothermal calorimetry analysis (KD = 3 nM), which also revealed that the interaction with CBD is strongly exothermic (DeltaG degrees = 48.6 kJ/mol, DeltaH = -75.3 kJ/mol, -TDeltaS degrees = 26.7 kJ/mol). The data provide insights in the molecular mechanisms that underlie the regulatory interaction of CHP3 and NHE1 and more general of calcineurin homologous proteins with their target proteins. PMID- 30287854 TI - Quantum Artificial Life in an IBM Quantum Computer. AB - We present the first experimental realization of a quantum artificial life algorithm in a quantum computer. The quantum biomimetic protocol encodes tailored quantum behaviors belonging to living systems, namely, self-replication, mutation, interaction between individuals, and death, into the cloud quantum computer IBM ibmqx4. In this experiment, entanglement spreads throughout generations of individuals, where genuine quantum information features are inherited through genealogical networks. As a pioneering proof-of-principle, experimental data fits the ideal model with accuracy. Thereafter, these and other models of quantum artificial life, for which no classical device may predict its quantum supremacy evolution, can be further explored in novel generations of quantum computers. Quantum biomimetics, quantum machine learning, and quantum artificial intelligence will move forward hand in hand through more elaborate levels of quantum complexity. PMID- 30287855 TI - Ropeginterferon alpha-2b targets JAK2V617F-positive polycythemia vera cells in vitro and in vivo. AB - Polycythemia vera is characterized by the acquisition of the JAK2V617F mutation. Recommended treatments include hydroxyurea and interferon-alpha. Several groups have reported a reduction in the JAK2 mutant allele burden in interferon-treated patients, but significance of this observation is questioned. We characterized the activity of ropeginterferon alpha-2b, a novel form of interferon-alpha recently shown to be safe and efficacious in polycythemia vera. Ropeginterferon was able to inhibit the proliferation of the HEL, UKE-1, and UT-7 JAK2-mutant cell lines while sparing JAK2-wild-type UT-7 and normal CD34+ cells growth. In vitro treatment of erythroid progenitors derived from PV patients showed that ropeginterferon could considerably inhibit the growth of endogenous erythroid colonies, a hallmark of polycythemia vera. Finally, we could study in sequential samples the clonal architecture of erythroid progenitors derived from patients included in a randomized study comparing hydroxyurea to ropeginterferon. After 1 year of treatment with ropeginterferon, the ratio of JAK2-mutated to wild-type colonies grown from bone marrow progenitors was reduced by 64%, compared to 25% in patients receiving hydroxyurea. This study shows that ropeginterferon has a potent targeted activity against JAK2-mutant cells and is able to drastically reduce the proportion of malignant progenitors in patients treated with this drug. PMID- 30287857 TI - Self-triggered Asynchronous Optical Sampling Terahertz Spectroscopy using a Bidirectional Mode-locked Fiber Laser. AB - We report a self-triggered asynchronous optical sampling terahertz spectroscopy system based on a single bidirectional mode-locked fiber laser and plasmonics enhanced photoconductive nanoantennas. The fiber laser generates two optical mutually coherent pulse trains with a stable repetition rate difference, enabling time-domain terahertz spectroscopy without using any mechanical delay line, stabilization electronics, or external trigger. The resolved terahertz spectra over a 0.1-2 THz frequency range and a 30-second measurement time show more than a 70-dB dynamic range, revealing water absorption lines matching the HITRAN database, through a light-weight and compact spectroscopy setup. PMID- 30287856 TI - Genome-wide association study identifies two risk loci for tuberculosis in Han Chinese. AB - Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis (Mtb), and remains a leading public health problem. Previous studies have identified host genetic factors that contribute to Mtb infection outcomes. However, much of the heritability in TB remains unaccounted for and additional susceptibility loci most likely exist. We perform a multistage genome-wide association study on 2949 pulmonary TB patients and 5090 healthy controls (833 cases and 1220 controls were genome-wide genotyped) from Han Chinese population. We discover two risk loci: 14q24.3 (rs12437118, Pcombined = 1.72 * 10-11, OR = 1.277, ESRRB) and 20p13 (rs6114027, Pcombined = 2.37 * 10-11, OR = 1.339, TGM6). Moreover, we determine that the rs6114027 risk allele is related to decreased TGM6 transcripts in PBMCs from pulmonary TB patients and severer pulmonary TB disease. Furthermore, we find that tgm6-deficient mice are more susceptible to Mtb infection. Our results provide new insights into the genetic etiology of TB. PMID- 30287858 TI - Leptin Increases Particle-Induced Osteolysis in Female ob/ob Mice. AB - Particles generated from wear of prosthesis joint bearing surfaces induce inflammation-mediated periprosthetic bone resorption (osteolysis). Morbidly obese leptin-deficient ob/ob mice are resistant to polyethylene particle-induced bone loss, suggesting that leptin, a hormone produced by adipocytes that circulates in concentrations proportional to total body adiposity, increases osteolysis. To confirm that particles induce less osteolysis in leptin-deficient mice after controlling for cold stress (room temperature)-induced bone loss, ob/ob mice on a C57BL/6 (B6) background and colony B6 wildtype (WT) mice housed at thermoneutral temperature were randomized to control or particle treatment groups (N = 5/group). Polyethylene particles were implanted over calvaria and mice sacrificed 2 weeks later. Compared to particle-treated WT mice, particle-treated ob/ob mice had lower osteolysis score, less infiltration of immune cells, and less woven bone formation. To determine the role of leptin in particle-induced osteolysis, ob/ob mice were randomized into one of 4 groups (n = 6-8/group): (1) control, (2) particles, (3) particles + continuous leptin (osmotic pump, 6 MUg/d), or (4) particles + intermittent leptin (daily injection, 40 MUg/d). Leptin treatment increased particle-induced osteolysis in ob/ob mice, providing evidence that the adpiokine may play a role in inflammation-driven bone loss. Additional research is required to determine whether altering leptin levels within the physiological range results in corresponding changes in polyethylene-particle-induced osteolysis. PMID- 30287859 TI - Risk of Incident Cardiovascular Disease and Cardiovascular Risk Factors in First and Second-Generation Indians: The Singapore Indian Eye Study. AB - Population-based data investigating generational differences in the risk of incident cardiovascular disease (CVD) and its risk determinants are rare. We examined the 6-year incidence of CVD and its risk factors in first- and second generation ethnic Indians living in Singapore. 1749 participants (mean age [SD]: 55.5 [8.8] years; 47.5% male) from a population-based, longitudinal study of Indian adults were included for incident CVD outcome. Incident CVD was defined as self-reported myocardial infarction, angina pectoris or stroke which developed between baseline and follow-up. CVD-related risk factors included incident diabetes, hypertension, hyperlipidemia, obesity and chronic kidney disease (CKD). For incident CVD outcome, of the 1749 participants, 406 (23.2%) and 1343 (76.8%) were first and second-generation Indians, respectively. Of these, 73 (4.1%) reported incident CVD. In multivariable models, second-generation individuals had increased risk of developing CVD (RR = 2.04; 95% CI 1.04, 3.99; p = 0.038), hyperlipidemia (RR = 1.27; 95% CI 1.06, 1.53; p = 0.011), and CKD (RR = 1.92; 95% CI 1.22, 3.04; p = 0.005), compared to first-generation Indians. Second generation Indians have increased risk of developing CVD and its associated risk factors such as hyperlipidemia and CKD compared to first-generation immigrants, independent of traditional CVD risk factors. More stratified and tailored CVD prevention strategies on second and subsequent generations of Indian immigrants in Singapore are warranted. PMID- 30287860 TI - Genome-wide analysis of horizontally acquired genes in the genus Mycobacterium. AB - Horizontal gene transfer (HGT) was attributed as a major driving force for the innovation and evolution of prokaryotic genomes. Previously, multiple research endeavors were undertaken to decipher HGT in different bacterial lineages. The genus Mycobacterium houses some of the most deadly human pathogens; however, the impact of HGT in Mycobacterium has never been addressed in a systematic way. Previous initiatives to explore the genomic imprints of HGTs in Mycobacterium were focused on few selected species, specifically among the members of Mycobacterium tuberculosis complex. Considering the recent availability of a large number of genomes, the current study was initiated to decipher the probable events of HGTs among 109 completely sequenced Mycobacterium species. Our comprehensive phylogenetic analysis with more than 9,000 families of Mycobacterium proteins allowed us to list several instances of gene transfers spread across the Mycobacterium phylogeny. Moreover, by examining the topology of gene phylogenies here, we identified the species most likely to donate and receive these genes and provided a detailed overview of the putative functions these genes may be involved in. Our study suggested that horizontally acquired foreign genes had played an enduring role in the evolution of Mycobacterium genomes and have contributed to their metabolic versatility and pathogenicity. PMID- 30287861 TI - Preparation of cationized gelatin nanospheres incorporating molecular beacon to visualize cell apoptosis. AB - The objective of this study is to prepare cationized gelatin nanospheres (cGNS) incorporating a molecular beacon (MB), and visualize cellular apoptosis. Two types of MB to detect the messenger RNA (mRNA) of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) (GAP MB), and caspase-3 (casp3 MB) were incorporated in cGNS, respectively. MB incorporated in cGNS showed the DNA sequence specificity in hybridization. The cGNS incorporation enabled MB to enhance the stability against nuclease to a significantly great extent compared with free MB. The cGNS incorporating GAP MB were internalized into the KUM6 of a mouse bone marrow derived stem cell by an endocytotic pathway. The cGNS were not distributed at the lysosomes. After the incubation with cGNS, the cell apoptosis was induced at different concentrations of camptothecin. No change in the intracellular fluorescence was observed for cGNSGAPMB. On the other hand, for the cGNScasp3MB, the fluorescent intensity significantly enhanced by the apoptosis induction of cells. It is concluded that cGNS incorporating MB is a promising system for the visualization of cellular apoptosis.

AB - The substitutional solid solutions composed of group VA-VIA nonmetallic elements has attracted considerable scientific interest since they provide a pressure induced route to search for novel types of solid solutions with potential applications. Yet, the pressure-induced solid solution phase is unprecedented in the sulfide family. In this paper, the structural behavior of antimony trisulfide, Sb2S3, has been investigated in order to testify whether or not it can also be driven into the substitutional solid solution phase by high pressures. The experiments were carried out by using a diamond anvil cell and angle dispersive synchrotron X-ray diffraction up to 50.2 GPa at room temperature. The experimental results indicate that Sb2S3 undergoes a series of phase transitions at 5.0, 12.6, 16.9, 21.3, and 28.2 GPa, and develops ultimately into an Sb-S substitutional solid solution, which adopts a body-centered cubic disordered structure. In this structure, the Sb and S atoms are distributed randomly on the bcc lattice sites with space group Im-3m. The structural behavior of Sb2S3 is tentatively assigned by comparison within the A2B3 (A = Sb, Bi; B = Se, Te, S) series under high pressures. PMID- 30287863 TI - Positive Caricature Transcriptomic Effects Associated with Broad Genomic Aberrations in Colorectal Cancer. AB - We re-examined the correlation between Broad Genomic Aberrations (BGAs) and transcriptomic profiles in Colorectal Cancer (CRC). Two types of BGAs have been examined: Broad Copy-Number Abnormal regions (BCNAs), distinguished in gain- and loss-type, and Copy-Neutral Loss of Heterozygosities (CNLOHs). Transcripts are classified as "OverT" or "UnderT" if overexpressed or underexpressed comparing CRCs bearing a specific BGA to CRCs not bearing it and as "UpT" or "DownT" if upregulated or downregulated in cancer compared to normal tissue. BGA-associated effects were evaluated by changes in the "Chromosomal Distribution Index" (CDI) of different transcript classes. Data show that UpT are more sensitive than DownT to BCNA-associated gene dosage effects. "Over-UpT" genes are upregulated in cancer and further overexpressed by gene dosage, defining the so called "positive caricature transcriptomic effect". When Over-UpT genes are ranked according to overexpression, top positions are occupied by genes implicated at the functional and therapeutic level in CRC. We show that cancer-upregulated transcripts are sensitive markers of BCNA-induced effects and suggest that analysis of positive caricature transcriptomic effects can provide clues toward the identification of BCNA-associated cancer driver genes. PMID- 30287864 TI - Potential identification of vitamin B6 responsiveness in autism spectrum disorder utilizing phenotype variables and machine learning methods. AB - We investigated whether machine learning methods could potentially identify a subgroup of persons with autism spectrum disorder (ASD) who show vitamin B6 responsiveness by selected phenotype variables. We analyzed the existing data from our intervention study with 17 persons. First, we focused on signs and biomarkers that have been identified as candidates for vitamin B6 responsiveness indicators. Second, we conducted hypothesis testing among these selected variables and their combinations. Finally, we further investigated the results by conducting cluster analyses with two different algorithms, affinity propagation and k-medoids. Statistically significant variables for vitamin B6 responsiveness, including combination of hypersensitivity to sound and clumsiness, and plasma glutamine level, were included. As an a priori variable, the Pervasive Developmental Disorders Autism Society Japan Rating Scale (PARS) scores was also included. The affinity propagation analysis showed good classification of three potential vitamin B6-responsive persons with ASD. The k-medoids analysis also showed good classification. To our knowledge, this is the first study to attempt to identify subgroup of persons with ASD who show specific treatment responsiveness using selected phenotype variables. We applied machine learning methods to further investigate these variables' ability to identify this subgroup of ASD, even when only a small sample size was available. PMID- 30287865 TI - Genome-wide association study reveals novel genetic locus associated with intra individual variability in response time. AB - Intra-individual response time variability (IIRTV) is proposed as a viable endophenotype for many psychiatric disorders, particularly attention-deficit hyperactivity disorder (ADHD). Here we assessed whether IIRTV was associated with common DNA variation genome-wide and whether IIRTV mediated the relationship between any associated loci and self-reported ADHD symptoms. A final data set from 857 Australian young adults (489 females and 368 males; Mage = 22.14 years, SDage = 4.82 years) who completed five response time tasks and self-reported symptoms of ADHD using the Conners' Adult ADHD Rating Scale was used. Principal components analysis (PCA) on these response time measures (standard deviation of reaction times and the intra-individual coefficient of variation) produced two variability factors (labelled response selection and selective attention). To understand the genetic drivers of IIRTV we performed a genome-wide association analysis (GWAS) on these PCA-derived indices of IIRTV. For the selective attention variability factor, we identified one single-nucleotide polymorphism (SNP) attaining genome-wide significance; rs62182100 in the HDAC4 gene located on chromosome 2q37. A bootstrapping mediation analysis demonstrated that the selective attention variability factor mediated the relationship between rs62182100 and self-reported ADHD symptoms. Our findings provide the first evidence of a genome-wide significant SNP association with IIRTV and support the potential utility of IIRTV as a valid endophenotype for ADHD symptoms. However, limitations of this study suggest that these observations should be interpreted with caution until replication samples become available. PMID- 30287867 TI - Long noncoding RNA Meg3 regulates cardiomyocyte apoptosis in myocardial infarction. AB - Myocardial infarction (MI), with a major process of cardiomyocyte death, remains a leading cause of morbidity and mortality worldwide. To date, it has been shown that lncRNAs play important roles in cardiovascular pathology. However, the detailed studies on lncRNAs regulating cardiomyocyte death in myocardial infarction are still limited. In this study, we found a progressively upregulated expression of Meg3 in mouse injured heart after MI. Gain-of-function and loss-of function approaches further revealed pro-apoptotic functions of Meg3 in rodent cardiomyocytes. Moreover, Meg3 was directly upregulated by p53 in hypoxic condition, and involved in apoptotic regulation via its direct binding with RNA binding protein FUS (fused in sarcoma). Afterwards, adult MI mice that underwent intramyocardial injection with adeno-associated virus serotype 9 (AAV9) system carrying Meg3 shRNA showed a significant improvement of cardiac function. Moreover, we also found that MEG3 was increased in clinical heart failure samples, and had conservatively pro-apoptotic function in human cardiomyocytes that were differentiated from the human embryonic stem cells. Together, these results indicate that p53-induced Meg3-FUS complex plays an important role in cardiomyocyte apoptosis post-MI, and its specific knockdown in cardiomyocytes with AAV9 system represents a promising method to treat MI for preclinical investigation. PMID- 30287869 TI - Improving carrier mobility of polycrystalline Ge by Sn doping. AB - To improve the performance of electronic devices, extensive research efforts have recently focused on the effect of incorporating Sn into Ge. In the present work, we investigate how Sn composition x (0 <= x <= 0.12) and deposition temperature Td (50 <= Td <= 200 degrees C) of the Ge1-xSnx precursor affect subsequent solid phase crystallization. Upon incorporating 3.2% Sn, which is slightly above the solubility limit of Sn in Ge, the crystal grain size increases and the grain boundary barrier decreases, which increases the hole mobility from 80 to 250 cm2/V s. Furthermore, at Td = 125 degrees C, the hole mobility reaches 380 cm2/V s, which is tentatively attributed to the formation of a dense amorphous GeSn precursor. This is the highest hole mobility for semiconductor thin films on insulators formed below 500 degrees C. These results thus demonstrate the usefulness of Sn doping of polycrystalline Ge and the importance of temperature while incorporating Sn. These findings make it possible to fabricate advanced Ge based devices including high-speed thin-film transistors. PMID- 30287868 TI - Continuous theta-burst stimulation over the dorsolateral prefrontal cortex inhibits improvement on a working memory task. AB - Theta-burst stimulation (TBS) over the dorsolateral prefrontal cortex (DLPFC) may be more effective for modulating cortical excitability compared to standard repetitive transcranial magnetic stimulation. However, the impact of intermittent (iTBS) and continuous TBS (cTBS) on working memory (WM) is poorly studied. The aim of our study was to compare the effects of iTBS and cTBS on WM over the left and right DLPFC. iTBS, cTBS or sham stimulation was administered over the right and left hemisphere of fifty-one healthy human subjects. WM was assessed before and after TBS using the 1-back, 2-back, and 3-back tasks. We found classical practice effects in the iTBS and the sham group: WM performance improved following stimulation as measured by the discriminability index. However, this effect could not be observed in the cTBS group. We did not find any hemisphere dependent effects, suggesting that the practice effect is not lateralized, and TBS affects WM performance in a comparable manner if administered either over the left or the right hemisphere. We propose that our findings represent a useful addition to the literature of TBS-induced effects on WM. Moreover, these results indicate the possibility of clarifying processes underlying WM performance changes by using non-invasive brain stimulation. PMID- 30287866 TI - Large-scale transcriptome-wide association study identifies new prostate cancer risk regions. AB - Although genome-wide association studies (GWAS) for prostate cancer (PrCa) have identified more than 100 risk regions, most of the risk genes at these regions remain largely unknown. Here we integrate the largest PrCa GWAS (N = 142,392) with gene expression measured in 45 tissues (N = 4458), including normal and tumor prostate, to perform a multi-tissue transcriptome-wide association study (TWAS) for PrCa. We identify 217 genes at 84 independent 1 Mb regions associated with PrCa risk, 9 of which are regions with no genome-wide significant SNP within 2 Mb. 23 genes are significant in TWAS only for alternative splicing models in prostate tumor thus supporting the hypothesis of splicing driving risk for continued oncogenesis. Finally, we use a Bayesian probabilistic approach to estimate credible sets of genes containing the causal gene at a pre-defined level; this reduced the list of 217 associations to 109 genes in the 90% credible set. Overall, our findings highlight the power of integrating expression with PrCa GWAS to identify novel risk loci and prioritize putative causal genes at known risk loci. PMID- 30287870 TI - Serum GFAP as a biomarker for disease severity in multiple sclerosis. AB - While neurofilament light chain (NfL) measurement in serum is a well-established marker of neuroaxonal damage in multiple sclerosis (MS), data on astroglial markers in serum are missing. In our study, glial fibrillary acid protein (GFAP) and NfL were measured in cerebrospinal fluid (CSF) and serum of MS patients and patients with other non-inflammatory neurological diseases (OND) using the Simoa technology. Clinical data like age, gender, expanded disability status scale (EDSS) and MRI findings were correlated to neurochemical markers. We included 80 MS patients: 42 relapsing-remitting MS (RRMS), 38 progressive MS (PMS), as well as 20 OND. Serum GFAP levels were higher in PMS compared to RRMS and OND (p < 0.001, p = 0.02 respectively). Serum GFAP levels correlated with disease severity in the whole MS group and PMS (Spearman-rho = 0.5, p < 0.001 in both groups). Serum GFAP correlated with serum NfL in PMS patients (Spearman-rho = 0.4, p = 0.01). Levels of serum GFAP were higher with increasing MRI-lesion count (p = 0.01). in summary, we report elevated levels of GFAP in the serum of MS patients. Since serum levels of GFAP correlate with the clinical severity scores and MRI lesion count, especially in PMS patients, it might be a suitable disease progression marker. PMID- 30287871 TI - Risk assessment of prolonged jaundice in infants at one month of age: A prospective cohort study. AB - Prolonged jaundice is a commonly evaluated condition. The aim of this study was to assess the risk factors of jaundice in healthy infants at one month of age. This prospective cohort study enrolled 509 healthy infants from 2013 to 2018. Those with gestational age (GA) less than 35 weeks, birth weight less than 2000 grams, and illness were not enrolled. Jaundice was defined as a transcutaneous bilirubin value >=5 mg/dL at 25-45 days of age. Umbilical cord blood samples were obtained to examine seven common gene variants. The incidence of prolonged jaundice was 32.2%. Prolonged jaundice was more common in infants with exclusive breastfeeding (p < 0.001), GA 35~37 w (p = 0.001), stool passage >4 times/d (p < 0.001), previous phototherapy (p < 0.001), and gene variant of G to A at nt 211 of UGT1A1 (p = 0.004). A multivariate logistic regression analysis demonstrated the greatest risk for prolonged jaundice was exclusive breastfeeding (OR = 2.818, 95% CI = 1.851-4.292), followed by previous phototherapy (OR = 2.593, 95% CI = 1.716-3.919), GA 35~37 w (OR = 2.468, 95% CI = 1.350-4.512), and G to A at nt 211 of UGT1A1 (OR = 1.645, 95% CI = 1.070-2.528). In conclusion, infants with exclusive breastfeeding, GA 35~37 w, previous phototherapy, or G to A at nt 211 of UGT1A1 are at greater risk of prolonged jaundice. Healthcare professionals should consider these risk factors in their assessment of prolonged jaundice.

PMID- 30287874 TI - Direct Thermal Growth of Large Scale Cl-doped CdTe Film for Low Voltage High Resolution X-ray Image Sensor. AB - Polycrystalline cadmium telluride (CdTe) X-ray photodetector with advanced performance was fabricated in a Schottky diode form by direct thermal deposition (evaporation) on pixelized complementary metal oxide semiconductor (CMOS) readout panel. Our CdTe X-ray detector shows such a variety of benefits as relatively low process temperature, low cost, low operation voltage less than 40 V, and higher sensitivity and spatial resolution than those of commercial a-Se detectors. CdTe has cubic Zinc Blende structure and maintains p-type conduction after growth in general. For low voltage operation, we succeeded in Cl doping at all stage of CdTe film deposition, and as a result, hole concentration of p-type CdTe was reduced to ~1012 cm-3 from ~1015 cm-3, and such concentration reduction could enable our Schottky diode with Ti electrode to operate at a reverse bias of less than 40 V. Our CdTe Schottky diode/CMOS pixel array as a direct conversion type imager demonstrates much higher resolution X-ray imaging in 7 * 9 cm2 large scale than that of CsI/CMOS array, an indirect conversion imager. To our limited knowledge, our results on polycrystalline CdTe Schottky diode/CMOS array would be very novel as a first demonstration of active pixel sensor system equipped with directly deposited large scale X-ray detector. PMID- 30287873 TI - Low dose dimethyl sulfoxide driven gross molecular changes have the potential to interfere with various cellular processes. AB - Dimethyl sulfoxide (DMSO) is a small molecule with polar, aprotic and amphiphilic properties. It serves as a solvent for many polar and nonpolar molecules and continues to be one of the most used solvents (vehicle) in medical applications and scientific research. To better understand the cellular effects of DMSO within the concentration range commonly used as a vehicle (0.1-1.5%, v/v) for cellular treatments, we applied Attenuated Total Reflectance (ATR) Fourier Transform Infrared (FT-IR) spectroscopy to DMSO treated and untreated epithelial colon cancer cells. Both unsupervised (Principal Component Analysis-PCA) and supervised (Linear Discriminant Analysis-LDA) pattern recognition/modelling algorithms applied to the IR data revealed total segregation and prominent differences between DMSO treated and untreated cells at whole, lipid and nucleic acid regions. Several of these data were supported by other independent techniques. Further IR data analyses of macromolecular profile indicated comprehensive alterations especially in proteins and nucleic acids. Protein secondary structure analysis showed predominance of beta-sheet over alpha-helix in DMSO treated cells. We also observed for the first time, a reduction in nucleic acid level upon DMSO treatment accompanied by the formation of Z-DNA. Molecular docking and binding free energy studies indicated a stabilization of Z-DNA in the presence of DMSO. This alternate DNA form may be related with the specific actions of DMSO on gene expression, differentiation, and epigenetic alterations. Using analytical tools combined with molecular and cellular biology techniques, our data indicate that even at very low concentrations, DMSO induces a number of changes in all macromolecules, which may affect experimental outcomes where DMSO is used as a solvent.

AB - Medications are available that can be highly effective for the treatment of inflammatory bowel disease (IBD). However, there are multiple barriers in place to offer these treatments to the right patients at the right time. In addition to obstacles created by payers, there are concerns over medication side effects by patients and providers, and the logistic challenges of navigating the maze of initiating someone on biological therapy. As a gastroenterology community, we need to push the field forward for the sake of our patients. Current and future drug development for IBD is exciting, but we need to optimize what we have now to the best of our ability. When used appropriately and early enough in the disease course, our current medications can heal the bowel and prevent complications from developing. While recognizing that all patients do not need early intensive therapy, we need to identify the appropriate patients for more aggressive treatments. This article will describe how we can improve patient management now by shifting our focus to using a personalized, proactive, and patient-centered approach in our delivery of IBD care. PMID- 30287875 TI - Prolonged bacterial lag time results in small colony variants that represent a sub-population of persisters. AB - Persisters are a subpopulation of bacteria that are not killed by antibiotics even though they lack genetic resistance. Here we provide evidence that persisters can manifest as small colony variants (SCVs) in clinical infections. We analyze growth kinetics of Staphylococcus aureus sampled from in vivo conditions and in vitro stress conditions that mimic growth in host compartments. We report that SCVs arise as a result of a long lag time, and that this phenotype emerges de novo during the growth phase in various stress conditions including abscesses and acidic media. We further observe that long lag time correlates with antibiotic usage. These observations suggest that treatment strategies should be carefully tailored to address bacterial persisters in clinics. PMID- 30287876 TI - Mutation pattern analysis reveals polygenic mini-drivers associated with relapse after surgery in lung adenocarcinoma. AB - The genomic lesions found in malignant tumours exhibit a striking degree of heterogeneity. Many tumours lack a known driver mutation, and their genetic basis is unclear. By mapping the somatic mutations identified in primary lung adenocarcinomas onto an independent coexpression network derived from normal tissue, we identify a critical gene network enriched for metastasis-associated genes. While individual genes within this module were rarely mutated, a significant accumulation of mutations within this geneset was predictive of relapse in lung cancer patients that have undergone surgery. Since it is the density of mutations within this module that is informative, rather than the status of any individual gene, these data are in keeping with a 'mini-driver' model of tumorigenesis in which multiple mutations, each with a weak effect, combine to form a polygenic driver with sufficient power to significantly alter cell behaviour and ultimately patient outcome. These polygenic mini-drivers therefore provide a means by which heterogeneous mutation patterns can generate the consistent hallmark changes in phenotype observed across tumours. PMID- 30287879 TI - Upregulation of Nav1.6 expression in the rostral ventrolateral medulla of stress induced hypertensive rats. AB - The rostral ventrolateral medulla (RVLM) plays a key role in mediating the development of stress-induced hypertension (SIH) by excitation and/or inhibition of sympathetic preganglionic neurons. The voltage-gated sodium channel Nav1.6 has been found to contribute to neuronal hyperexcitability. To examine the expression of Nav1.6 in the RVLM during SIH, a rat model was established by administering electric foot-shocks and noises. We found that Nav1.6 protein expression in the RVLM of SIH rats was higher than that of control rats, peaking at the tenth day of stress. Furthermore, we observed changes in blood pressure correlating with days of stress, with systolic blood pressure (SBP) found to reach a similarly timed peak at the tenth day of stress. Percentages of cells exhibiting colocalization of Nav1.6 with NeuN, a molecular marker of neurons, indicated a strong correlation between upregulation of Nav1.6 expression in NeuN-positive cells and SBP. The level of RSNA was significantly increased after 10 days of stress induction than control group. Compared with the SIHR, knockdown of Nav1.6 in RVLM of the SIHR decreased the level of SBP, heart rate (HR) and renal sympathetic nerve activity (RSNA). These results suggest that upregulated Nav1.6 expression within neurons in the RVLM of SIH rats may contribute to overactivation of the sympathetic system in response to SIH development. PMID- 30287878 TI - Influence of water quality on diversity and composition of fungal communities in a tropical river. AB - Freshwater fungi are key decomposers of organic material and play important roles in nutrient cycling, bio-remediation and ecosystem functioning. Although aquatic fungal communities respond to pollution, few studies have quantitatively assessed the effect of freshwater contamination on fungal diversity and composition; and knowledge is scarcer for tropical systems. Here we help fill this knowledge gap by studying a heavily-contaminated South American river spanning a biodiversity hotspot. We collected 30 water samples scattered across a quality gradient over two seasons and analyzed them using Terminal Restriction Fragment Length Polymorphisms (T-RFLP) coupled with 454 Pyrosequencing. Using T-RFLP we identified 451 and 442 Operational Taxonomy Units (OTUs) in the dry and rainy seasons respectively, whereas Pyrosequencing revealed 48,553 OTUs from which 11% were shared between seasons. Although 68% of all identified OTUs and 51% of all identified phyla remained unidentified, dominant fungal phyla included the Ascomycota, Basidiomycota, Chytridiomycota, Glomeromycota, Zygomycota and Neocallimastigomycota, while Calcarisporiella, Didymosphaeria, Mycosphaerella (Ascomycota) and Rhodotorula (Basidiomycota) were the most abundant genera. Fungal diversity was affected by pH and dissolved iron, while community composition was influenced by dissolved oxygen, pH, nitrate, biological oxygen demand, total aluminum, total organic carbon, total iron and seasonality. The presence of potentially pathogenic species was associated with high pH. Furthermore, geographic distance was positively associated with community dissimilarity, suggesting that local conditions allowed divergence among fungal communities. Overall, our findings raise potential concerns for human health and the functioning of tropical river ecosystems and they call for improved water sanitation systems. PMID- 30287881 TI - Stimulated Brillouin Scattering in an AlGaN Photonics Platform Operating in the Visible Spectral Range. AB - We present Stimulated Brillouin Scattering (SBS) process in AlGaN integrated photonic waveguides. The wide bandgap of this III-Nitride material platform allows operating at visible wavelengths enabling large Stokes shifts. For this study, we employ a multiphysics approach that includes electric-photoelastic, magnetic-photoelastic, material interface displacement effects, and for optimal waveguide dimensions to find the Brillouin-active acoustic modes involved in the SBS process. The SBS power gain and the Stokes frequency shift are investigated for both backward and forward scattering processes, and it is shown that stokes shift larger than 50 GHz with high gain are achievable. Moreover, a parametric analysis is presented in order to demonstrate the possibility of realizing Brillouin lasers operating at blue wavelengths. PMID- 30287880 TI - Mutation of TP53, translocation analysis and immunohistochemical expression of MYC, BCL-2 and BCL-6 in patients with DLBCL treated with R-CHOP. AB - Diffuse large B-cell lymphoma (DLBCL) is an aggressive lymphoma with diverse outcomes. Concurrent translocation of MYC and BCL-2 and/or BCL-6, and concurrent immunohistochemical (IHC) high expression of MYC and BCL-2, have been linked to unfavorable treatment responses. TP53-mutated DLBCL has also been linked to worse outcome. Our aim was to evaluate the aforementioned issues in a cohort of 155 patients uniformly treated with R-CHOP-like therapies. We performed direct sequencing of TP53 exons 5, 6, 7 and 8 as well as fluorescence in-situ hybridization (FISH) of MYC, BCL-2 and BCL-6, and IHC of MYC, BCL-2 and BCL-6. In multivariate analysis, TP53 mutations in L3 and loop-sheet helix (LSH) associated with a risk ratio (RR) of disease-specific survival (DSS) of 8.779 (p = 0.022) and a RR of disease-free survival (DFS) of 10.498 (p = 0.011). In IHC analysis BCL-2 overexpression was associated with inferior DFS (p = 0.002) and DSS (p = 0.002). DLBCL with BCL-2 and MYC overexpression conferred inferior survival in all patients (DSS, p = 0.038 and DFS, p = 0.011) and in patients with non-GC phenotype (DSS (p = 0.013) and DFS (p = 0.010). Our results imply that in DLBCL, the location of TP53 mutations and IHC analysis of BCL-2 and MYC might have a role in the assessment of prognosis.

PMID- 30287882 TI - Two Engineered OBPs with opposite temperature-dependent affinities towards 1 aminoanthracene. AB - Engineered odorant-binding proteins (OBPs) display tunable binding affinities triggered by temperature alterations. We designed and produced two engineered proteins based on OBP-I sequence: truncated OBP (tOBP) and OBP::GQ20::SP-DS3. The binding affinity of 1-aminoanthracene (1-AMA) to these proteins revealed that tOBP presents higher affinity at 25 degrees C (kd = 0.45 MUM) than at 37 degrees C (kd = 1.72 MUM). OBP::GQ20::SP-DS3 showed an opposite behavior, revealing higher affinity at 37 degrees C (kd = 0.58 MUM) than at 25 degrees C (kd = 1.17 MUM). We set-up a system containing both proteins to evaluate their temperature-dependent binding. Our data proved the 1-AMA differential and reversible affinity towards OBPs, triggered by temperature changes. The variations of the binding pocket size with temperature, confirmed by molecular modelling studies, were determinant for the differential binding of the engineered OBPs. Herein we described for the first time a competitive temperature dependent mechanism for this class of proteins. PMID- 30287884 TI - Clock transition by continuous dynamical decoupling of a three-level system. AB - We present a novel continuous dynamical decoupling scheme for the construction of a robust qubit in a three-level system. By means of a clock transition adjustment, we first show how robustness to environmental noise is achieved, while eliminating drive-noise, to first-order. We demonstrate this scheme with the spin sub-levels of the NV-centre's electronic ground state. By applying drive fields with moderate Rabi frequencies, the drive noise is eliminated and an improvement of 2 orders of magnitude in the coherence time is obtained compared to the pure dephasing time. We then show how the clock transition adjustment can be tuned to eliminate also the second-order effect of the environmental noise with moderate drive fields. A further detailed theoretical investigation suggests an additional improvement of more than 1 order of magnitude in the coherence time which is supported by simulations. Hence, our scheme predicts that the coherence time may be prolonged towards the lifetime-limit using a relatively simple experimental setup. PMID- 30287885 TI - Genome analyses of uncultured TG2/ZB3 bacteria in 'Margulisbacteria' specifically attached to ectosymbiotic spirochetes of protists in the termite gut. AB - We investigated the phylogenetic diversity, localisation and metabolism of an uncultured bacterial clade, Termite Group 2 (TG2), or ZB3, in the termite gut, which belongs to the candidate phylum 'Margulisbacteria'. We performed 16S rRNA amplicon sequencing analysis and detected TG2/ZB3 sequences in 40 out of 72 termite and cockroach species, which exclusively constituted a monophyletic cluster in the TG2/ZB3 clade. Fluorescence in situ hybridisation analysis in lower termites revealed that these bacteria are specifically attached to ectosymbiotic spirochetes of oxymonad gut protists. Draft genomes of four TG2/ZB3 phylotypes from a small number of bacterial cells were reconstructed, and functional genome analysis suggested that these bacteria hydrolyse and ferment cellulose/cellobiose to H2, CO2, acetate and ethanol. We also assembled a draft genome for a partner Treponema spirochete and found that it encoded genes for reductive acetogenesis from H2 and CO2. We hypothesise that the TG2/ZB3 bacteria we report here are commensal or mutualistic symbionts of the spirochetes, exploiting the spirochetes as H2 sinks. For these bacteria, we propose a novel genus, 'Candidatus Termititenax', which represents a hitherto uncharacterised class-level clade in 'Margulisbacteria'. Our findings add another layer, i.e., cellular association between bacteria, to the multi-layered symbiotic system in the termite gut. PMID- 30287886 TI - 'NetShift': a methodology for understanding 'driver microbes' from healthy and disease microbiome datasets. AB - The combined effect of mutual association within the co-inhabiting microbes in human body is known to play a major role in determining health status of individuals. The differential taxonomic abundance between healthy and disease are often used to identify microbial markers. However, in order to make a microbial community based inference, it is important not only to consider microbial abundances, but also to quantify the changes observed among inter microbial associations. In the present study, we introduce a method called 'NetShift' to quantify rewiring and community changes in microbial association networks between healthy and disease. Additionally, we devise a score to identify important microbial taxa which serve as 'drivers' from the healthy to disease. We demonstrate the validity of our score on a number of scenarios and apply our methodology on two real world metagenomic datasets. The 'NetShift' methodology is also implemented as a web-based application available at https://web.rniapps.net/netshift. PMID- 30287888 TI - Statistical testing for baseline differences between randomised groups is not meaningful. PMID- 30287887 TI - Device-independent quantum random-number generation. AB - Randomness is important for many information processing applications, including numerical modelling and cryptography1,2. Device-independent quantum random-number generation (DIQRNG)3,4 based on the loophole-free violation of a Bell inequality produces genuine, unpredictable randomness without requiring any assumptions about the inner workings of the devices, and is therefore an ultimate goal in the field of quantum information science5-7. Previously reported experimental demonstrations of DIQRNG8,9 were not provably secure against the most general adversaries or did not close the 'locality' loophole of the Bell test. Here we present DIQRNG that is secure against quantum and classical adversaries10-12. We use state-of-the-art quantum optical technology to create, modulate and detect entangled photon pairs, achieving an efficiency of more than 78 per cent from creation to detection at a distance of about 200 metres that greatly exceeds the threshold for closing the 'detection' loophole of the Bell test. By independently and randomly choosing the base settings for measuring the entangled photon pairs and by ensuring space-like separation between the measurement events, we also satisfy the no-signalling condition and close the 'locality' loophole of the Bell test, thus enabling the realization of the loophole-free violation of a Bell inequality. This, along with a high-voltage, high-repetition-rate Pockels cell modulation set-up, allows us to accumulate sufficient data in the experimental time to extract genuine quantum randomness that is secure against the most general adversaries. By applying a large (137.90 gigabits * 62.469 megabits) Toeplitz-matrix hashing technique, we obtain 6.2469 * 107 quantum-certified random bits in 96 hours with a total failure probability (of producing a random number that is not guaranteed to be perfectly secure) of less than 10-5. Our demonstration is a crucial step towards transforming DIQRNG from a concept to a key aspect of practical applications that require high levels of security and thus genuine randomness7. Our work may also help to improve our understanding of the origin of randomness from a fundamental perspective. PMID- 30287890 TI - Exploration of potential biochemical markers for persistence of patent ductus arteriosus in preterm infants at 22-27 weeks' gestation. AB - BACKGROUND: Early identification of infants at risk for complications from patent ductus arteriosus (PDA) may improve treatment outcomes. The aim of this study was to identify biochemical markers associated with persistence of PDA, and with failure of pharmacological treatment for PDA, in extremely preterm infants. METHODS: Infants born at 22-27 weeks' gestation were included in this prospective study. Blood samples were collected on the second day of life. Fourteen biochemical markers associated with factors that may affect PDA closure were analyzed and related to persistent PDA and to the response of pharmacological treatment with ibuprofen. RESULTS: High levels of B-type natriuretic peptide, interleukin-6, -8, -10, and -12, growth differentiation factor 15 and monocyte chemotactic protein 1 were associated with persistent PDA, as were low levels of platelet-derived growth factor. High levels of erythropoietin were associated with both persistent PDA and failure to close PDA within 24 h of the last dose of ibuprofen. CONCLUSIONS: High levels of inflammatory markers were associated with the persistence of PDA. High levels of erythropoietin were associated with both the persistence of PDA and failure to respond to pharmacological treatment. PMID- 30287891 TI - Gene ontology enrichment analysis of congenital diaphragmatic hernia-associated genes. AB - BACKGROUND: Congenital diaphragmatic hernia (CDH) is a commonly occurring major congenital anomaly with a profound impact on neonatal mortality. The etiology of CDH is poorly understood and is complicated by multiple clinical presentations, reflecting the location and type of diaphragm defect. With the increased power of genetic screening, more genes are being associated with CDH, creating a knowledge gap between CDH-associated genes and their contribution to diaphragm embryogenesis. METHODS: Our goal was to investigate CDH-associated genes and identify common pathways that may lead to abnormal diaphragm development. A comprehensive list of CDH-associated genes was identified from the literature and categorized according to multiple factors, including type of CDH. We undertook a large-scale gene function analysis using gene ontology to identify significantly enriched biological pathways and molecular functions associated with our gene set. RESULTS: We identified 218 CDH-associated genes. Our gene ontology analysis showed that genes representing distinct biological pathways are significantly enriched in relation to different clinical presentations of CDH. This includes retinoic acid signaling in Bochdalek CDH, myogenesis in diaphragm eventration, and angiogenesis in central tendon defects. CONCLUSIONS: We have identified unique genotype-phenotype relationships highlighting the major genetic drivers of the different types of CDH. PMID- 30287889 TI - Molecular characterization, antimicrobial resistance and clinico-bioinformatics approaches to address the problem of extended-spectrum beta-lactamase-producing Escherichia coli in western Saudi Arabia. AB - The goal of this study was to genotypically characterize extended-spectrum beta lactamase-producing Escherichia coli isolates from the western region of Saudi Arabia and to identify active antibiotics against these isolates using phenotypic and molecular modeling. In total, 211 ESBL-producing E. coli isolates recovered from heterogeneous clinical specimens were identified by MALDI-TOF. Thirty-two sequence types (STs) were identified from a multilocus sequence typing (MLST) analysis of ESBL-producing E. coli, including a novel ST (ST8162). The most common ST in the Saudi and expatriate population was ST131, followed by ST38. All the isolates were multidrug resistant (MDR), and >95% of the isolates were resistant to third-generation (ceftriaxone and ceftazidime) and fourth-generation (cefepime) cephalosporins. The ESBL-positive E. coli isolates primarily harbored the blaCTX-M and blaTEM genes. No resistance was observed against the carbapenem antibiotic group. All the ESBL-producing E. coli isolates were observed to be susceptible to a ceftazidime/avibactam combination. Molecular interaction analyses of the docked complexes revealed the amino acid residues crucial for the binding of antibiotics and inhibitors to the modeled CTX-M-15 enzyme. Importantly, avibactam displayed the most robust interaction with CTX-M-15 among the tested inhibitors in the docked state (?G = -6.6 kcal/mol). The binding free energy values for clavulanate, tazobactam and sulbactam were determined to be 5.7, -5.9 and -5.2 kcal/mol, respectively. Overall, the study concludes that 'ceftazidime along with avibactam' should be carefully used as a treatment option against only carbapenem-resistant MDR ESBL-producing E. coli in this region. PMID- 30287892 TI - Body mass index classification misses to identify children with an elevated waist to-height ratio at 5 years of age. AB - BACKGROUND: Abdominal adiposity is an important risk factor in the metabolic syndrome. Since BMI does not reveal fat distribution, waist-to-height ratio (WHtR) has been suggested as a better measure of abdominal adiposity in children, but only a few studies cover the preschool population. The aim of the present study was to examine BMI and WHtR growth patterns and their association regarding their ability to identify children with an elevated WHtR at 5 years of age. METHODS: A population-based longitudinal birth cohort study of 1540 children, followed from 0 to 5 years with nine measurement points. The children were classified as having WHtR standard deviation scores (WHtRSDS) <1 or >=1 at 5 years. Student's t-tests and Chi-squared tests were used in the analyses. RESULTS: Association between BMISDS and WHtRSDS at 5 years showed that 55% of children with WHtRSDS >=1 at 5 years had normal BMISDS (p < 0.001). Children with WHtRSDS >=1 at 5 years had from an early age significantly higher mean BMISDS and WHtRSDS than children with values <1. CONCLUSIONS: BMI classification misses every second child with WHtRSDS >=1 at 5 years, suggesting that WHtR adds value in identifying children with abdominal adiposity who may need further investigation regarding cardiometabolic risk factors. PMID- 30287893 TI - Capturing the statewide incidence of neonatal abstinence syndrome in real time: the West Virginia experience. AB - BACKGROUND: Neonatal abstinence syndrome (NAS) is one of the consequences at birth affecting the newborn after discontinuation of prenatal drug exposure to mainly opioids. The objective of this study was to determine the extent of the problem in the state of West Virginia (WV) using a real-time statewide surveillance system. METHODS: Project WATCH is a surveillance tool that since 1998 collects data on all infants born in the state of WV. NAS surveillance item was added to the tool in October 2016. This study examined all births (N = 23,667) in WV from October to December 2017. The data from six WV birthing facilities were audited for 1 month to evaluate how well this tool was capturing NAS data using kappa-statistics. RESULTS: The 2017 annual incidence rate of NAS was 51.3 per 1000 live births per year for all births and 50.6 per 1000 live births per year for WV residents only. The kappa-coefficient between the hospital medical records and Project WATCH data was 0.74 (95% confidence interval: 0.66 0.82) for NAS. CONCLUSION: The study provides justification to develop effective systems of care for the mother-infant dyad affected by substance use, especially targeting pregnant women in rural communities. PMID- 30287894 TI - Serum L-carnitine and vitamin D levels may be low among oral sildenafil citrate non-responders. AB - This cross-sectional comparative study aimed to compare serum L-carnitine and 25(OH)D levels between men with ED non-responding for oral sildenafil citrate and healthy volunteers. Overall, 192 men, recruited from two University Hospitals, were allocated into two equal groups of matched age; healthy potent men and men with ED non-responders for oral sildenafil citrate. Oral sildenafil citrate non responders self-reported inadequate erectile responses after four attempts using 100 mg with the manufacturer's guidelines relative to meals, associated medications, and sexual stimulation/arousal. Exclusion criteria were: diabetes, cardiovascular disorders, beta blockers treatment, morbid obesity, thyroid disorders, post-radical prostatectomy, and hepatic/renal failure. All participants were subjected to; history taking, clinical examination, validated IIEF-5 questionnaire, estimation of serum L-carnitine by calorimetric method and serum 25(OH)D by ELISA method. Compared with potent controls, ED men non responders for oral sildenafil citrate showed significant decreases in the mean serum L-carnitine level (16.8 +/- 3.6 uM/L versus 66.3 +/- 11.9 uM/L, P = 0.001), the mean serum 25(OH)D level (21.2 +/- 7.1 ng/ml versus 54.6 +/- 7.9 ng/mL, P = 0.001) and IIEF-5 score (7.8 +/- 2.6 versus 23.9 +/- 1.3). Serum L-carnitine showed significant positive correlation with IIEF-5 scores (r = 0.873, P = 001), serum 25(OH)D (r = 0.796, P = 0.001) and significant negative correlation with the age (r = -0.515, P = 0.001). Serum 25(OH)D showed significant positive correlation with IIEF-5 scores (r = 0.855, P = 0.001) and significant negative correlation with the age (r = -0.223, P = 0.005). It is concluded that normal homeostasis of serum L-carnitine and 25(OH)D play a role in male sexual health being significantly decreased in ED non-responding for oral sildenafil citrate.

AB - Each year millions of newborns are part of a newborn disease-screening program in which, after initial screening, the newborn dried blood spot (NDBS) samples can be stored and used as a population-based research resource. However, very little knowledge exists about how these samples are used for secondary purposes. Our objective is to estimate and describe the usage of a NDBS-based national population biobank for secondary research purposes. We therefore conducted a scoping study with a literature search for all published articles using samples from the Danish Newborn Screening Biobank. Our main inclusion criteria were that the articles had to have actively used and analyzed one or more of the Danish NDBS samples for a purpose beyond the primary screening. Our search led to a final 104 articles, which were coded for three main purposes: (1) how many samples were used in each article, (2) the field of their research, and (3) information on consent and ethics approval as research. From our analysis, we present two main findings: an estimated use of up to 37.5% of all samples in the newborn screening biobank have been part of published research, and a shift in the research areas from methodological and metabolic studies to studies concerning mental illness. This paper provides new insights into the use of a national biobank, and we hope that the results will contribute to the discussions on the use of biological samples for research purposes, and also inspire a greater transparency in the future use of NDBS samples. PMID- 30287899 TI - Presymptomatic genetic testing for hereditary cancer in young adults: a survey of young adults and parents. AB - Presymptomatic testing for hereditary cancer syndromes should involve a considered choice. This may be particularly challenging when testing is undertaken in early adulthood. With the aim of exploring the psychosocial implications of presymptomatic testing for hereditary cancer in young adults and their parents, a cross-sectional survey was designed. Two questionnaires were developed (one for young adults who had considered presymptomatic testing, one for parents). Questionnaires were completed by 152 (65.2%) young adults and 42 (73.7%) parents. Data were analysed using descriptive statistics, inferential testing, and exploratory factor analysis and linear regression analysis. Young adults were told about their potential genetic risk at a mean age of 20 years; in most cases, information was given by a parent, often in an unplanned conversation. Although testing requests were usually made by young adults, the majority of parents felt they had control over the young adult's decision and all felt their children should be tested. Results suggest that some young adults did not understand the implications of the genetic test but complied with parental pressure. Counselling approaches for presymptomatic testing may require modification both for young adults and their parents. Those offering testing need to be aware of the complex pressures that young adults can experience, which can influence their autonomous choices. It is therefore important to emphasise to both parents and young adults that, although testing can bring benefits in terms of surveillance and prevention, young adults have a choice. PMID- 30287897 TI - A multisubstrate reductase from Plantago major: structure-function in the short chain reductase superfamily. AB - The short chain dehydrogenase/reductase superfamily (SDR) is a large family of NAD(P)H-dependent enzymes found in all kingdoms of life. SDRs are particularly well-represented in plants, playing diverse roles in both primary and secondary metabolism. In addition, some plant SDRs are also able to catalyse a reductive cyclisation reaction critical for the biosynthesis of the iridoid backbone that contains a fused 5 and 6-membered ring scaffold. Mining the EST database of Plantago major, a medicinal plant that makes iridoids, we identified a putative 5beta-progesterone reductase gene, PmMOR (P. major multisubstrate oxido reductase), that is 60% identical to the iridoid synthase gene from Catharanthus roseus. The PmMOR protein was recombinantly expressed and its enzymatic activity assayed against three putative substrates, 8-oxogeranial, citral and progesterone. The enzyme demonstrated promiscuous enzymatic activity and was able to not only reduce progesterone and citral, but also to catalyse the reductive cyclisation of 8-oxogeranial. The crystal structures of PmMOR wild type and PmMOR mutants in complex with NADP+ or NAD+ and either 8-oxogeranial, citral or progesterone help to reveal the substrate specificity determinants and catalytic machinery of the protein. Site-directed mutagenesis studies were performed and provide a foundation for understanding the promiscuous activity of the enzyme. PMID- 30287901 TI - Autoreactive T cells in narcolepsy. PMID- 30287900 TI - FGF-7 Dictates Osteocyte Cell Processes Through Beta-Catenin Transduction. AB - It is well recognized that osteocytes communicate with each other via gap junctions and that connxin43 (Cx43) shows its great potential in gap junction for the contribution enabling transmission of small molecules and operating in an autocrine/a paracrine manner. Fibroblast growth factors (FGFs) play significant roles in new bone formation and adult bone remodeling, and FGF signaling is regulated by the precise spatiotemporal approaches. However, the influence of FGF7 on osteocyte cell processes is not well elucidated. In this study, we aimed to examine the impact of FGF7 on osteocyte cell processes by characterizing the expression of Cx43 and to reveal the underlying mechanism regulating this cell process. We first found that the mRNA level of FGF7 was higher relative to other FGF family members both in osteocytes cell line (MLO-Y4) and bone tissue. We then demonstrated that FGF7 could increase the expression of Cx43 in osteocytes and promote the cell processes in the form of gap junctions between osteocytes. This modulation was due to the FGF7-induced cytoplasmic accumulation and resultant nuclear translocation of beta-catenin. Our results could help us to further understand the importance of FGF7 on bone cell behavior and bone physiology and even pathology. PMID- 30287902 TI - Repurposing of promoters and enhancers during mammalian evolution. AB - Promoters and enhancers-key controllers of gene expression-have long been distinguished from each other based on their function. However, recent work suggested that common architectural and functional features might have facilitated the conversion of one type of element into the other during evolution. Here, based on cross-mammalian analyses of epigenome and transcriptome data, we provide support for this hypothesis by detecting 445 regulatory elements with signatures of activity turnover (termed P/E elements). Most events represent transformations of putative ancestral enhancers into promoters, leading to the emergence of species-specific transcribed loci or 5' exons. Distinct GC sequence compositions and stabilizing 5' splicing (U1) regulatory motif patterns may have predisposed P/E elements to regulatory repurposing, and changes in the U1 and polyadenylation signal densities and distributions likely drove the evolutionary activity switches. Our work suggests that regulatory repurposing facilitated regulatory innovation and the origination of new genes and exons during evolution. PMID- 30287905 TI - Who improves from coma, how do they improve, and then what? PMID- 30287903 TI - Determination of the Main Phase Transition Temperature of Phospholipids by Nanoplasmonic Sensing. AB - Our study demonstrates that nanoplasmonic sensing (NPS) can be utilized for the determination of the phase transition temperature (Tm) of phospholipids. During the phase transition, the lipid bilayer undergoes a conformational change. Therefore, it is presumed that the Tm of phospholipids can be determined by detecting conformational changes in liposomes. The studied lipids included 1,2 dipalmitoyl-sn-glycero-3-phosphocholine (DPPC), 1,2-dimyristoyl-sn-glycero-3 phosphocholine (DMPC), and 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC). Liposomes in gel phase are immobilized onto silicon dioxide sensors and the sensor cell temperature is increased until passing the Tm of the lipid. The results show that, when the system temperature approaches the Tm, a drop of the NPS signal is observed. The breakpoints in the temperatures are 22.5 degrees C, 41.0 degrees C, and 55.5 degrees C for DMPC, DPPC, and DSPC, respectively. These values are very close to the theoretical Tm values, i.e., 24 degrees C, 41.4 degrees C, and 55 degrees C for DMPC, DPPC, and DSPC, respectively. Our studies prove that the NPS methodology is a simple and valuable tool for the determination of the Tm of phospholipids. PMID- 30287904 TI - Pattern to Knowledge: Deep Knowledge-Directed Machine Learning for Residue Residue Interaction Prediction. AB - Residue-residue close contact (R2R-C) data procured from three-dimensional protein-protein interaction (PPI) experiments is currently used for predicting residue-residue interaction (R2R-I) in PPI. However, due to complex physiochemical environments, R2R-I incidences, facilitated by multiple factors, are usually entangled in the source environment and masked in the acquired data. Here we present a novel method, P2K (Pattern to Knowledge), to disentangle R2R-I patterns and render much succinct discriminative information expressed in different specific R2R-I statistical/functional spaces. Since such knowledge is not visible in the data acquired, we refer to it as deep knowledge. Leveraging the deep knowledge discovered to construct machine learning models for sequence based R2R-I prediction, without trial-and-error combination of the features over external knowledge of sequences, our R2R-I predictor was validated for its effectiveness under stringent leave-one-complex-out-alone cross-validation in a benchmark dataset, and was surprisingly demonstrated to perform better than an existing sequence-based R2R-I predictor by 28% (p: 1.9E-08). P2K is accessible via our web server on https://p2k.uwaterloo.ca . PMID- 30287906 TI - A cross-species approach to disorders affecting brain and behaviour. AB - Structural and functional elements of biological systems are highly conserved across vertebrates. Many neurological and psychiatric conditions affect both humans and animals. A cross-species approach to the study of brain and behaviour can advance our understanding of human disorders via the identification of unrecognized natural models of spontaneous disorders, thus revealing novel factors that increase vulnerability or resilience, and via the assessment of potential therapies. Moreover, diagnostic and therapeutic advances in human neurology and psychiatry can often be adapted for veterinary patients. However, clinical and research collaborations between physicians and veterinarians remain limited, leaving this wealth of comparative information largely untapped. Here, we review pain, cognitive decline syndromes, epilepsy, anxiety and compulsions, autoimmune and infectious encephalitides and mismatch disorders across a range of animal species, looking for novel insights with translational potential. This comparative perspective can help generate novel hypotheses, expand and improve clinical trials and identify natural animal models of disease resistance and vulnerability. PMID- 30287907 TI - Photoacclimation strategies in northeastern Atlantic seagrasses: Integrating responses across plant organizational levels. AB - Seagrasses live in highly variable light environments and adjust to these variations by expressing acclimatory responses at different plant organizational levels (meadow, shoot, leaf and chloroplast level). Yet, comparative studies, to identify species' strategies, and integration of the relative importance of photoacclimatory adjustments at different levels are still missing. The variation in photoacclimatory responses at the chloroplast and leaf level were studied along individual leaves of Cymodocea nodosa, Zostera marina and Z. noltei, including measurements of variable chlorophyll fluorescence, photosynthesis, photoprotective capacities, non-photochemical quenching and D1-protein repair, and assessments of variation in leaf anatomy and chloroplast distribution. Our results show that the slower-growing C. nodosa expressed rather limited physiological and biochemical adjustments in response to light availability, while both species of faster-growing Zostera showed high variability along the leaves. In contrast, the inverse pattern was found for leaf anatomical adjustments in response to light availability, which were more pronounced in C. nodosa. This integrative plant organizational level approach shows that seagrasses differ in their photoacclimatory strategies and that these are linked to the species' life history strategies, information that will be critical for predicting the responses of seagrasses to disturbances and to accordingly develop adequate management strategies. PMID- 30287908 TI - Metabarcoding of marine environmental DNA based on mitochondrial and nuclear genes. AB - We establish the new approach of environmental DNA (eDNA) analyses for the North Sea. Our study uses a multigene approach, including the mitochondrial cytochrome c-oxidase subunit I (COI) gene for analyzing species composition and the nuclear hypervariable region V8 of 18S rDNA for analyzing supraspecific biodiversity. A new minibarcode primer (124 bp) was created on the basis of a metazoan COI barcode library with 506 species and tested in silico, in vitro, and in situ. We applied high throughput sequencing to filtrates of 23 near-bottom water samples taken at three seasons from 14 stations. The set of COI primers allowed amplification of mitochondrial minibarcodes for diverse metazoan phyla and the differentiation at the species level for more than 99% of the specimens in the dataset. Our results revealed that the number of sequences is not consistent with proportions in the given DNA mixture. Altogether, environmental sequences could be assigned to 114 species and to 12 metazoan phyla. A spatial distribution of taxa recovered by eDNA was congruent with known distributions. Finally, the successful detection of species and biodiversity depends on a comprehensive sequence reference database. Our study offers a powerful tool for future biodiversity research, including the detection of nonnative species. PMID- 30287909 TI - Polymorphisms at phase I-metabolizing enzyme and hormone receptor loci influence the response to anti-TNF therapy in rheumatoid arthritis patients. AB - The aim of this case-control study was to evaluate whether 47 single-nucleotide polymorphisms (SNPs) in steroid hormone-related genes are associated with the risk of RA and anti-TNF drug response. We conducted a case-control study in 3 European populations including 2936 RA patients and 2197 healthy controls. Of those, a total of 1985 RA patients were treated with anti-TNF blockers. The association of potentially interesting markers in the discovery population was validated through meta-analysis with data from DREAM and DANBIO registries. Although none of the selected variants had a relevant role in modulating RA risk, the meta-analysis of the linear regression data with those from the DREAM and DANBIO registries showed a significant correlation of the CYP3A4rs11773597 and CYP2C9rs1799853 variants with changes in DAS28 after the administration of anti TNF drugs (P = 0.00074 and P = 0.006, respectively). An overall haplotype analysis also showed that the ESR2GGG haplotype significantly associated with a reduced chance of having poor response to anti-TNF drugs (P = 0.0009). Finally, a ROC curve analysis confirmed that a model built with eight steroid hormone related variants significantly improved the ability to predict drug response compared with the reference model including demographic and clinical variables (AUC = 0.633 vs. AUC = 0.556; PLR_test = 1.52 * 10-6). These data together with those reporting that the CYP3A4 and ESR2 SNPs correlate with the expression of TRIM4 and ESR2 mRNAs in PBMCs (ranging from P = 1.98 * 10-6 to P = 2.0 * 10-35), and that the CYP2C9rs1799853 SNP modulates the efficiency of multiple drugs, suggest that steroid hormone-related genes may have a role in determining the response to anti-TNF drugs.KEY POINTS* Polymorphisms within the CYP3A4 and CYP2C9 loci correlate with changes in DAS28 after treatment with anti-TNF drugs.* A haplotype including eQTL SNPs within the ESR2 gene associates with better response to anti-TNF drugs.* A genetic model built with eight steroid hormone related variants significantly improved the ability to predict drug response. PMID- 30287910 TI - Pharmacogenomics in epithelial ovarian cancer first-line treatment outcome: validation of GWAS-associated NRG3 rs1649942 and BRE rs7572644 variants in an independent cohort. AB - The identification of predictive biomarkers for the first-line treatment of epithelial ovarian cancer (EOC) remains a challenge. Although genome-wide association studies (GWAS) have identified several genetic polymorphisms as predictors of EOC clinical outcome, the subsequent validation has not yet been performed. This study aims to validate the influence of Neuregulin 3 (NRG3) rs1649942 and Brain and reproductive organ-expressed (TNFRSF1A modulator) (BRE) rs7572644 GWAS-identified variants in an independent cohort of EOC patients from the North region of Portugal (n = 339) submitted to first-line treatment. Polymorphism genotypes were determined by real-time PCR using validated assays. Patients carrying the NRG3 rs1649942 A allele presented a significantly longer overall survival (OS) when compared to GG-genotype patients (log-rank test, P = 0.011) in the FIGO IV stage subgroup. No impact was observed for early-stage patients or considering disease-free survival (DFS) as an outcome. For FIGO I/II stage patients, BRE rs7572644 C allele carriers exhibit a decreased OS (P = 0.014) and DFS (P = 0.032) when compared to TT-homozygous patients. Furthermore, a Multivariate Cox regression analysis revealed a three-fold increase in the risk of death (HR, 3.09; P = 0.015) and recurrence (HR, 3.33; P = 0.009) for FIGO I/II C allele carriers. No significant impact was observed for late-stage patients. The BRE rs7572644 and NRG3 rs1649942 genetic variants were validated in an independent cohort of EOC Portuguese patients, particularly in specific subgroups considering FIGO staging. Further functional post-GWAS analyses are indispensable to understand the biological mechanisms underlying the observed results. PMID- 30287911 TI - Association between SOST gene polymorphisms and response to alendronate treatment in postmenopausal Chinese women with low bone mineral density. AB - The aim of this study was to explore the allelic association between SOST polymorphisms and the variance of clinical effects of alendronate in postmenopausal Chinese women with osteoporosis or osteopenia. In the study, 500 postmenopausal women in Shanghai area with osteoporosis or osteopenia were included. All participants were treated with weekly oral alendronate 70 mg, daily calcium 600 mg and vitamin D 125 IU for 12 months. Nine tagging single-nucleotide polymorphisms (SNPs) in SOST gene were genotyped. Bone mineral density of lumbar spine (L1-L4), left femoral neck and total hip were measured at baseline and after 1 year of treatment, respectively. In the study, 450 subjects completed the 1-year follow-up. The rs865429 was significantly associated with the % change of BMD at the femoral neck (P = 0.007). GG carriers seemed to be at an advantage after treatment of alendronate. Compared with AG and AA heterozygote, GG homozygote had the highest % change of BMD (3.100 +/- 2.899%) at femoral neck. The odds ratio (95% confidence) of GG homozygote to be responders at femoral neck was 1.921 (1.211-3.048). Two haplotypes GG and AC constituted by rs865429 and rs851057 were associated with the % change of BMD at femoral neck and total hip, respectively. Therefore, the common variation of SOST gene contribute to the therapeutic response to alendronate treatment in Chinese women with osteoporosis or osteopenia. PMID- 30287912 TI - Oenological traits of Lachancea thermotolerans show signs of domestication and allopatric differentiation. AB - The yeast Lachancea thermotolerans (previously Kluyveromyces thermotolerans) is a species of large, yet underexplored, oenological potential. This study delivers comprehensive oenological phenomes of 94 L. thermotolerans strains obtained from diverse ecological niches worldwide, classified in nine genetic groups based on their pre-determined microsatellite genotypes. The strains and the genetic groups were compared for their alcoholic fermentation performance, production of primary and secondary metabolites and pH modulation in Chardonnay grape juice fermentations. The common oenological features of L. thermotolerans strains were their glucophilic character, relatively extensive fermentation ability, low production of acetic acid and the formation of lactic acid, which significantly affected the pH of the wines. An untargeted analysis of volatile compounds, used for the first time in a population-scale phenotyping of a non-Saccharomyces yeast, revealed that 58 out of 90 volatiles were affected at an L. thermotolerans strain level. Besides the remarkable extent of intra-specific diversity, our results confirmed the distinct phenotypic performance of L. thermotolerans genetic groups. Together, these observations provide further support for the occurrence of domestication events and allopatric differentiation in L. thermotolerans population. PMID- 30287913 TI - Ultra-wide-band structural slow light. AB - The ability of using integrated photonics to scale multiple optical components on a single monolithic chip offers key advantages to create miniature light controlling chips. Numerous scaled optical components have been already demonstrated. However, present integrated photonic circuits are still rudimentary compared to the complexity of today's electronic circuits. Slow light propagation in nanostructured materials is a key component for realizing chip-integrated photonic devices controlling the relative phase of light and enhancing optical nonlinearities. We present an experimental record high group-index-bandwidth product (GBP) of 0.47 over a 17.7 nm bandwidth in genetically optimized coupled cavity-waveguides (CCWs) formed by L3 photonic crystal cavities. Our structures were realized in silicon-on-insulator slabs integrating up to 800 coupled cavities, and characterized by transmission, Fourier-space imaging of mode dispersion, and Mach-Zehnder interferometry. PMID- 30287914 TI - The colorectal cancer epidemic: challenges and opportunities for primary, secondary and tertiary prevention. AB - Colorectal cancer (CRC) is both one of the most common and one of the most preventable cancers globally, with powerful but strongly missed potential for primary, secondary and tertiary prevention. CRC incidence has traditionally been the highest in affluent Western countries, but it is now increasing rapidly with economic development in many other parts of the world. CRC shares several main risk factors, such as smoking, excessive alcohol consumption, physical inactivity and being overweight, with other common diseases; therefore, primary prevention efforts to reduce these risk factors are expected to have multiple beneficial effects that extend beyond CRC prevention, and should have high public health impact. A sizeable reduction in the incidence and mortality of CRC can also be achieved by offering effective screening tests, such as faecal immunochemical tests, flexible sigmoidoscopy and colonoscopy, in organised screening programmes which have been implemented in an increasing number of countries. Countries with early and high uptake rates of effective screening have exhibited major declines in CRC incidence and mortality, in contrast to most other countries. Finally, increasing evidence shows that the prognosis and quality of life of CRC patients can be substantially improved by tertiary prevention measures, such as the administration of low-dose aspirin and the promotion of physical activity. PMID- 30287915 TI - Hierarchical clustering of activated proteins in the PI3K and MAPK pathways in ER positive, HER2-negative breast cancer with potential therapeutic consequences. AB - BACKGROUND: The phosphatidylinositol-3-kinase (PI3K) and/or mitogen-activated protein kinase (MAPK) pathways are frequently activated in breast cancer which can result in antioestrogen resistance. Single protein markers failed to be introduced into clinical practice. We, therefore, aimed to find a better read-out of activation of the PI3K and MAPK pathways in ER+/HER2- breast cancer. Assessment of seven PI3K/MAPK proteins might better reflect pathway activation and distinguish patients without adjuvant tamoxifen benefit. METHODS: Tumour blocks were recollected from 293 primary postmenopausal ER+/HER2- breast cancer patients randomised between tamoxifen and no adjuvant therapy. PTEN, p AKT(Thr308), p-AKT(Ser473), p-p70S6K, p-4EBP1, p-ERK1/2 and p-S6RP expression was assessed by immunohistochemistry followed by unsupervised hierarchical clustering. The primary endpoint was recurrence-free interval. Multivariate Cox models were used to assess tamoxifen benefit. A classification tool was developed based on protein expression profile. RESULTS: Subgroups were identified with preferentially activated (A) and preferentially not activated (N) proteins. Patients in group N derived significant benefit from tamoxifen (multivariate hazard ratio (HR) = 0.23, p = 0.000101), while patients from group A did not (multivariate HR = 1.37, p = 0.64), p for interaction 0.020. Our generated classification tool confirmed these results (p for interaction 0.024). CONCLUSIONS: Hierarchical clustering of seven PI3K/MAPK proteins reflects pathway activation and can guide treatment decisions in primary ER+/HER2- postmenopausal breast cancer patients. PMID- 30287917 TI - Analysis of cell proliferation and tissue remodelling uncovers a KLF4 activity score associated with poor prognosis in colorectal cancer. AB - BACKGROUND: Human cancers can be classified based on gene signatures quantifying the degree of cell proliferation and tissue remodelling (PR). However, the specific factors that drive the increased tissue remodelling in tumours are not fully understood. Here we address this question using colorectal cancer as a case study. METHODS: We reanalysed a reported cohort of colorectal cancer patients. The patients were stratified based on gene signatures of cell proliferation and tissue remodelling. Putative transcription factors activity was inferred using gene expression profiles and annotations of transcription factor targets as input. RESULTS: We demonstrate that the PR classification performs better than the currently adopted consensus molecular subtyping (CMS). Although CMS classification differentiates patients with a mesenchymal signature, it cannot distinguish the remaining patients based on survival. We demonstrate that the missing factor is cell proliferation, which is indicative of good prognosis. We also uncover a KLF4 transcription factor activity score associated with the tissue remodelling gene signature. We further show that the KLF4 activity score is significantly higher in colorectal tumours with predicted infiltration of cells from the myeloid lineage. CONCLUSION: The KLF4 activity score is associated with tissue remodelling, myeloid cell infiltration and poor prognosis in colorectal cancer. PMID- 30287916 TI - Kallikrein-related peptidases 4, 5, 6 and 7 regulate tumour-associated factors in serous ovarian cancer. AB - BACKGROUND: Tissue kallikrein-related peptidases 4, 5, 6 and 7 (KLK4-7) strongly increase the malignancy of ovarian cancer cells. Deciphering their downstream effectors, we aimed at finding new potential prognostic biomarkers and treatment targets for ovarian cancer patients. KLK4-7-transfected (OV-KLK4-7) and vector control OV-MZ-6 (OV-VC) ovarian cancer cells were established to select differentially regulated factors. METHODS: With three independent approaches, PCR arrays, genome-wide microarray and proteome analyses, we identified 10 candidates (MSN, KRT19, COL5A2, COL1A2, BMP5, F10, KRT7, JUNB, BMP4, MMP1). To determine differential protein expression, we performed western blot analyses, immunofluorescence and immunohistochemistry for four candidates (MSN, KRT19, KRT7, JUNB) in cells, tumour xenograft and patient-derived tissues. RESULTS: We demonstrated that KLK4-7 clearly regulates expression of MSN, KRT19, KRT7 and JUNB at the mRNA and protein levels in ovarian cancer cells and tissues. Protein expression of the top-upregulated effectors, MSN and KRT19, was investigated by immunohistochemistry in patients afflicted with serous ovarian cancer and related to KLK4-7 immunoexpression. Significant positive associations were found for KRT19/KLK4, KRT19/KLK5 and MSN/KLK7. CONCLUSION: These findings imply that KLK4-7 exert key modulatory effects on other cancer-related genes and proteins in ovarian cancer. These downstream effectors of KLK4-7, MSN and KRT19 may represent important therapeutic targets in serous ovarian cancer. PMID- 30287918 TI - Differences in DNA methylation profiles by histologic subtype of paediatric germ cell tumours: a report from the Children's Oncology Group. AB - BACKGROUND: Abnormal DNA methylation may be important in germ cell tumour (GCT) aetiology, as germ cells undergo complete epigenetic reprogramming during development. GCTs show differences in global and promoter methylation patterns by histologic subtype. We conducted an epigenome-wide study to identify methylation differences by GCT histology. METHODS: Using the Illumina HumanMethylation450K array we measured methylation in 154 paediatric GCTs (21 germinomas/seminomas/dysgerminoma, 70 yolk sac tumours [YST], 9 teratomas, and 54 mixed histology tumours). We identified differentially methylated regions (DMRs) between GCT histologies by comparing methylation beta values. RESULTS: We identified 8,481 DMRs (FWER < 0.05). Unsupervised hierarchical clustering of individual probes within DMRs resulted in four high level clusters closely corresponding to tumour histology. Clusters corresponding to age, location, sex and FFPE status were not observed within these DMRs. Germinomas displayed lower levels of methylation across the DMRs relative to the other histologic subtypes. Pathway analysis on the top 10% of genes with differential methylation in germinomas/seminomas/dysgerminoma compared to YST suggested angiogenesis and immune cell-related pathways displayed decreased methylation in germinomas/seminomas/dysgerminoma relative to YST. CONCLUSIONS: Paediatric GCT histologies have differential methylation patterns. The genes that are differentially methylated may provide insights into GCT aetiology including the timing of GCT initiation. PMID- 30287919 TI - Targeting peroxiredoxin 1 impairs growth of breast cancer cells and potently sensitises these cells to prooxidant agents. AB - BACKGROUND: Our previous work has shown peroxiredoxin-1 (PRDX1), one of major antioxidant enzymes, to be a biomarker in human breast cancer. Hereby, we further investigate the role of PRDX1, compared to its close homolog PRDX2, in mammary malignant cells. METHODS: CRISPR/Cas9- or RNAi-based methods were used for genetic targeting PRDX1/2. Cell growth was assessed by crystal violet, EdU incorporation or colony formation assays. In vivo growth was assessed by a xenotransplantation model. Adenanthin was used to inhibit the thioredoxin dependent antioxidant defense system. The prooxidant agents used were hydrogen peroxide, glucose oxidase and sodium L-ascorbate. A PY1 probe or HyPer-3 biosensor were used to detect hydrogen peroxide content in samples. RESULTS: PRDX1 downregulation significantly impaired the growth rate of MCF-7 and ZR-75-1 breast cancer cells. Likewise, xenotransplanted PRDX1-deficient MCF-7 cells presented a retarded tumour growth. Furthermore, genetic targeting of PRDX1 or adenanthin, but not PRDX2, potently sensitised all six cancer cell lines studied, but not the non-cancerous cells, to glucose oxidase and ascorbate. CONCLUSIONS: Our study pinpoints the dominant role for PRDX1 in management of exogeneous oxidative stress by breast cancer cells and substantiates further exploration of PRDX1 as a target in this disease, especially when combined with prooxidant agents.

PMID- 30287920 TI - A Clinical Risk Prediction Tool for Peritonitis-Associated Treatment Failure in Peritoneal Dialysis Patients. AB - A tool to predict peritonitis-associated treatment failure among peritoneal dialysis (PD) patients has not yet been established. We conducted a multicentre, retrospective cohort study among 1,025 PD patients between 2006 and 2016 in Thailand to develop and internally validate such a tool. Treatment failure was defined as either a requirement for catheter removal, a switch to haemodialysis, or peritonitis-associated mortality. Prediction model performances were analysed using discrimination (C-statistics) and calibration (Hosmer-Lemeshow test) tests. Predictors were weighted to calculate a risk score. In total, 435 patients with 855 episodes of peritonitis were identified; 215 (25.2%) episodes resulted in treatment failure. A total risk score of 11.5 was developed including, diabetes, systolic blood pressure <90 mmHg, and dialysate leukocyte count >1,000/mm3 and >100/mm3 on days 3-4 and day 5, respectively. The discrimination (C-statistic = 0.92; 95%CI, 0.89-0.94) and calibration (P > 0.05) indicated an excellent performance. No significant difference was observed in the internal validation cohort. The rate of treatment failure in the different groups was 3.0% (low-risk, <1.5 points), 54.4% (moderate-risk, 1.5-9 points), and 89.5% (high-risk, >9 points). A simplified risk-scoring scheme to predict treatment failure may be useful for clinical decision making regarding PD patients with peritonitis. External validation studies are needed. PMID- 30287922 TI - Secondary findings from clinical genomic sequencing: prevalence, patient perspectives, family history assessment, and health-care costs from a multisite study. AB - PURPOSE: Clinical sequencing emerging in health care may result in secondary findings (SFs). METHODS: Seventy-four of 6240 (1.2%) participants who underwent genome or exome sequencing through the Clinical Sequencing Exploratory Research (CSER) Consortium received one or more SFs from the original American College of Medical Genetics and Genomics (ACMG) recommended 56 gene-condition pair list; we assessed clinical and psychosocial actions. RESULTS: The overall adjusted prevalence of SFs in the ACMG 56 genes across the CSER consortium was 1.7%. Initially 32% of the family histories were positive, and post disclosure, this increased to 48%. The average cost of follow-up medical actions per finding up to a 1-year period was $128 (observed, range: $0-$678) and $421 (recommended, range: $141-$1114). Case reports revealed variability in the frequency of and follow-up on medical recommendations patients received associated with each SF gene condition pair. Participants did not report adverse psychosocial impact associated with receiving SFs; this was corroborated by 18 participant (or parent) interviews. All interviewed participants shared findings with relatives and reported that relatives did not pursue additional testing or care. CONCLUSION: Our results suggest that disclosure of SFs shows little to no adverse impact on participants and adds only modestly to near-term health-care costs; additional studies are needed to confirm these findings. PMID- 30287923 TI - Standard operating procedure for somatic variant refinement of sequencing data with paired tumor and normal samples. AB - PURPOSE: Following automated variant calling, manual review of aligned read sequences is required to identify a high-quality list of somatic variants. Despite widespread use in analyzing sequence data, methods to standardize manual review have not been described, resulting in high inter- and intralab variability. METHODS: This manual review standard operating procedure (SOP) consists of methods to annotate variants with four different calls and 19 tags. The calls indicate a reviewer's confidence in each variant and the tags indicate commonly observed sequencing patterns and artifacts that inform the manual review call. Four individuals were asked to classify variants prior to, and after, reading the SOP and accuracy was assessed by comparing reviewer calls with orthogonal validation sequencing. RESULTS: After reading the SOP, average accuracy in somatic variant identification increased by 16.7% (p value = 0.0298) and average interreviewer agreement increased by 12.7% (p value < 0.001). Manual review conducted after reading the SOP did not significantly increase reviewer time. CONCLUSION: This SOP supports and enhances manual somatic variant detection by improving reviewer accuracy while reducing the interreviewer variability for variant calling and annotation. PMID- 30287924 TI - Putting genome-wide sequencing in neonates into perspective. AB - PURPOSE: Several studies have reported diagnostic yields up to 57% for rapid exome or genome sequencing (rES/GS) as a single test in neonatal intensive care unit (NICU) patients, but the additional yield of rES/GS compared with other available diagnostic options still remains unquantified in this population. METHODS: We retrospectively evaluated all genetic NICU consultations in a 2-year period. RESULTS: In 132 retrospectively evaluated NICU consultations 27 of 32 diagnoses (84.4%) were made using standard genetic workup. Most diagnoses (65.6%) were made within 16 days. Diagnostic ES yield was 5/29 (17.2%). Genetic diagnoses had a direct effect on clinical management in 90.6% (29/32) of patients. CONCLUSIONS: Our study shows that exome sequencing has a place in NICU diagnostics, but given the associated costs and the high yield of alternative diagnostic strategies, we recommend to first perform clinical genetic consultation. PMID- 30287926 TI - Histiocyte-rich rhabdomyoblastic tumor: rhabdomyosarcoma, rhabdomyoma, or rhabdomyoblastic tumor of uncertain malignant potential? A histologically distinctive rhabdomyoblastic tumor in search of a place in the classification of skeletal muscle neoplasms. AB - Skeletal muscle tumors are traditionally classified as rhabdomyoma or rhabdomyosarcoma. We have identified an unusual adult rhabdomyoblastic tumor not clearly corresponding to a previously described variant of rhabdomyoma or rhabdomyosarcoma, characterized by a very striking proliferation of non neoplastic histiocytes, obscuring the underlying tumor. Ten cases were identified in nine males and one female with a median age of 43 years (range 23-69 years). Tumors involved the deep soft tissues of the trunk (N = 4), lower limbs (N = 4), and neck (N = 2). Tumors were well-circumscribed, nodular masses, frequently surrounded by a fibrous capsule containing lymphoid aggregates and sometimes calcifications. Numerous foamy macrophages, multinucleated Touton-type giant cells, and sheets/fascicles of smaller, often spindled macrophages largely obscured the underlying desmin, MyoD1, and myogenin-positive rhabdomyoblastic tumor. Cases were wild type for MYOD1 and no other mutations or rearrangements characteristic of a known subtype of rhabdomyoma or rhabdomyosarcoma were identified. Two of four cases successfully analyzed using a next-generation sequencing panel of 170 common cancer-related genes harbored inactivating NF1 mutations. Next-generation sequencing showed no gene fusions. Clinical follow (nine patients; median 9 months; mean 23 months; range 3-124 months) showed all patients received wide excision; four patients also received adjuvant radiotherapy and none received chemotherapy. At the time of last follow-up, all patients were alive and without disease; no local recurrences or distant metastases occurred. We hypothesize that these unusual tumors represent rhabdomyoblastic tumors of uncertain malignant potential. Possibly over time they should be relegated to a new category of skeletal muscle tumors of intermediate (borderline) malignancy. PMID- 30287925 TI - Variants affecting diverse domains of MEPE are associated with two distinct bone disorders, a craniofacial bone defect and otosclerosis. AB - PURPOSE: To characterize new molecular factors implicated in a hereditary congenital facial paresis (HCFP) family and otosclerosis. METHODS: We performed exome sequencing in a four-generation family presenting nonprogressive HCFP and mixed hearing loss (HL). MEPE was analyzed using either Sanger sequencing or molecular inversion probes combined with massive parallel sequencing in 89 otosclerosis families, 1604 unrelated affected subjects, and 1538 unscreened controls. RESULTS: Exome sequencing in the HCFP family led to the identification of a rare segregating heterozygous frameshift variant p.(Gln425Lysfs*38) in MEPE. As the HL phenotype in this family resembled otosclerosis, we performed variant burden and variance components analyses in a large otosclerosis cohort and demonstrated that nonsense and frameshift MEPE variants were significantly enriched in affected subjects (p = 0.0006-0.0060). CONCLUSION: MEPE exerts its function in bone homeostasis by two domains, an RGD and an acidic serine aspartate-rich MEPE-associated (ASARM) motif inhibiting respectively bone resorption and mineralization. All variants associated with otosclerosis are predicted to result in nonsense mediated decay or an ASARM-and-RGD-truncated MEPE. The HCFP variant is predicted to produce an ASARM-truncated MEPE with an intact RGD motif. This difference in effect on the protein corresponds with the presumed pathophysiology of both diseases, and provides a plausible molecular explanation for the distinct phenotypic outcome. PMID- 30287928 TI - Nrf2 mediates the resistance of human A549 and HepG2 cancer cells to boningmycin, a new antitumor antibiotic, in vitro through regulation of glutathione levels. AB - NF-E2-related factor 2 (Nrf2) is a transcription factor and a pivotal factor in the induction of the cell defense system. Recent reports show that Nrf2 plays critical roles in tumor heterogeneity and drug resistance. In the present study we investigated whether and how Nrf2 mediated the resistance of human cancer cells to boningmycin (BON), a new antitumor antibiotic of the bleomycin family. We showed that in the expression levels of Nrf2 in human non-small lung cancer A549 cells were much higher than those in human hepatoblastoma HepG2 cells, and their resistance to BON was opposite to Nrf2 expression (the IC50values of BON in A549 cells and HepG2 cells were 5.97 and 0.61 MUmol/L, respectively). Similar results were observed with the anticancer agent cisdiamminedichloroplatinum (DDP), which was used as a positive control. In A549 cells, Nrf2 mRNA knockdown significantly increased their susceptibilities to BON and DDP. An enhanced resistance to BON and DDP was observed in HepG2 cells after overexpression of the wild-type Nrf2 protein. Treatment with a specific Nrf2 inhibitor, luteolin, significantly sensitized A549 cells to BON and DDP and increased BON- or DDP induced apoptosis. The total levels of glutathione (GSH), the final product of the Nrf2 signaling pathway, were much higher in A549 cells than those in HepG2 cells. Supplementation of GSH in HepG2 cells significantly decreased their susceptibility to BON and DDP, wheras depleting GSH with the specific inhibitor L buthionine sulfoximine in A549 cells significantly increased their susceptibility to BON and DDP. Our results demonstrate that Nrf2 mediates the resistance to BON through regulating glutathione levels in A549 cells and HepG2 cells. PMID- 30287929 TI - High-throughput ab initio calculations on dielectric constant and band gap of non oxide dielectrics. AB - High-k dielectrics, materials having a large band gap (Eg) and high dielectric constant (k) simultaneously, constitute critical components in microelectronic devices. Because of the inverse relationship between Eg and k, materials with large values in both properties are rare. Therefore, massive databases on Eg and k will be useful in identifying optimal high-k materials. While experimental and theoretical data on Eg and k of oxides are accumulating, corresponding information is scarce for non-oxide dielectrics with anions such as C, N, F, P, S, and Cl. To identify promising high-k dielectrics among these material groups, we screen 869 compounds of binary carbides, nitrides, sulfides, phosphides, chlorides, and fluorides, through automated ab initio calculations. Among these compounds, fluorides exhibit an Eg-k relation that is comparable to that of oxides. By further screening over ternary fluorides, we identify fluorides such as BiF3, LaF3, and BaBeF4 that could serve as useful high-k dielectrics. PMID- 30287927 TI - Laboratory diagnostics of murine blood for detection of mouse cytomegalovirus (MCMV)-induced hepatitis. AB - Mouse models are important and versatile tools to study mechanisms and novel therapies of human disease in vivo. Both, the number and the complexity of murine models are constantly increasing and modification of genes of interest as well as any exogenous challenge may lead to unanticipated biological effects. Laboratory diagnostics of blood samples provide a comprehensive and rapid screening for multiple organ function and are fundamental to detect human disease. Here, we adapt an array of laboratory medicine-based tests commonly used in humans to establish a platform for standardized, multi-parametric, and quality-controlled diagnostics of murine blood samples. We determined sex-dependent reference intervals of 51 commonly used laboratory medicine tests for samples obtained from the C57BL/6J mouse strain. As a proof of principle, we applied these diagnostic tests in a mouse cytomegalovirus (MCMV) infection model to screen for organ damage. Consistent with histopathological findings, plasma concentrations of liver-specific enzymes were elevated, supporting the diagnosis of a virus-induced hepatitis. Plasma activities of aminotransferases correlated with viral loads in livers at various days after MCMV infection and discriminated infected from non infected animals. This study provides murine blood reference intervals of common laboratory medicine parameters and illustrates the use of these tests for diagnosis of infectious disease in experimental animals.

PMID- 30287930 TI - Fast robust dose calculation on GPU for high-precision 1H, 4He, 12C and 16O ion therapy: the FRoG platform. AB - Radiotherapy with protons and heavier ions landmarks a novel era in the field of high-precision cancer therapy. To identify patients most benefiting from this technologically demanding therapy, fast assessment of comparative treatment plans utilizing different ion species is urgently needed. Moreover, to overcome uncertainties of actual in-vivo physical dose distribution and biological effects elicited by different radiation qualities, development of a reliable high throughput algorithm is required. To this end, we engineered a unique graphics processing unit (GPU) based software architecture allowing rapid and robust dose calculation. FRoG, Fast Recalculation on GPU, currently operates with four particle beams available at Heidelberg Ion Beam Therapy center, i.e., raster scanning proton (1H), helium (4He), carbon (12C) and oxygen ions (16O). FRoG enables comparative analysis of different models for estimation of physical and biological effective dose in 3D within minutes and in excellent agreement with the gold standard Monte Carlo (MC) simulation. This is a crucial step towards development of next-generation patient specific radiotherapy. PMID- 30287933 TI - Structural and functional body components in athletic health and performance phenotypes. AB - Advances in body composition assessment enable a detailed body composition analyses and the respective organization at different levels. Sports-related professionals are interested in understanding how and which body components are relevant for improving performance, prevent injury risk, and monitor athletic health. The aim of this review is to propose an integrative model that links performance, injury risk, and athletic health with body components, and to report their cross-sectional and longitudinal associations. Cross-sectional studies reveal that endurance athletes with higher fat mass (FM) show a longer race time, whereas a higher fat-free mass benefits power and strength-related tasks. Longitudinal studies indicated that increases in intracellular water, assessed through dilution techniques, were associated with power and strength improvements, independently of weight and lean-soft-tissue changes. There is evidence that athletes involved in weight-sensitive sports restrict energy intake, thus reducing energy availability (EA) and compromising bone health (Female Athlete Triad). To counteract the low EA and related negative energy balance, metabolic adaption (MA) occurs to promote energy conservation. Currently, reference values for body composition assessment using anthropometry and DXA are available for a few sports, according to sex. More research is needed to develop a functional body composition profile according to sports-specific requirements. PMID- 30287932 TI - Ex vivo assessment and in vivo validation of non-invasive stent monitoring techniques based on microwave spectrometry. AB - Some conditions are well known to be directly associated with stent failure, including in-stent re-occlusion and stent fracture. Currently, identification of these high-risk conditions requires invasive and complex procedures. This study aims to assess microwave spectrometry (MWS) for monitoring stents non-invasively. Preliminary ex vivo data are presented to move to in vivo validation. Fifteen mice were assigned to receive subcutaneous stent implantations (n = 10) or sham operations (n = 5). MWS measurements were carried out at 0, 2, 4, 7, 14, 22, and 29 days of follow-up. Additionally, 5 stented animals were summited to micro-CT analyses at the same time points. At 29 days, 3 animals were included into a stent fracture subgroup and underwent a last MWS and micro-CT analysis. MWS was able to identify stent position and in-stent stenosis over time, also discerning significant differences from baseline measures (P < 0.001). Moreover, MWS identified fractured vs. non-fractured stents in vivo. Taken together, MWS emerges as a non-invasive, non-ionizing alternative for stent monitoring. MWS analysis clearly distinguished between in-stent stenosis and stent fracture phenomena. PMID- 30287934 TI - Association between Geriatric Nutrition Risk Index and low muscle mass in Chinese elderly people. AB - BACKGROUND/OBJECTIVES: The aim of the study was to evaluate the relationship between Geriatric Nutrition Risk Index (GNRI) and low muscle mass (LMM) in elderly people. SUBJECTS/METHODS: A cross-sectional study was carried out in Chinese PLA General Hospital with 3240 participants who underwent a health check up examination between February 2016 and February 2017. Linear regression and logistic regression were used to examine the relationship between GNRI and LMM. RESULTS: The mean age of the participants in the study was 64.6 years. The mean appendicular skeletal muscle mass index (ASMI) was 8.92 +/- 0.93 kg/m2 in men and 7.62 +/- 0.73 kg/m2 in women. The incidences of LMM were 7.9% in men and 3.7% in women. Linear regression demonstrated that GNRIs were positively correlated with ASMIs in both men and women (beta = 0.055 for men and 0.039 for women, all P < 0.001). The cut-off point of the GNRI in elderly people for LMM was 104.0 in men and 107.0 in women and were identified by Classification and Regression Trees (CART). Logistic regression showed that both men and women with decreased GNRIs had higher ratios of LMM [odds ratio (OR) = 3.904 for men and 4.486 for women, P < 0.001 and P = 0.001, respectively]. CONCLUSIONS: Elderly people with a low GNRI had a higher incidence of LMM, which suggested that GNRI had a close relationship with LMM and that it could be a good indicator in identifying senior people who need further nutritional support and physical activity. PMID- 30287935 TI - The biology and treatment of Merkel cell carcinoma: current understanding and research priorities. AB - Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer associated with advanced age and immunosuppression. Over the past decade, an association has been discovered between MCC and either integration of the Merkel cell polyomavirus, which likely drives tumorigenesis, or somatic mutations owing to ultraviolet induced DNA damage. Both virus-positive and virus-negative MCCs are immunogenic, and inhibition of the programmed cell death protein 1 (PD-1)-programmed cell death 1 ligand 1 (PD-L1) immune checkpoint has proved to be highly effective in treating patients with metastatic MCC; however, not all patients have a durable response to immunotherapy. Despite these rapid advances in the understanding and management of patients with MCC, many basic, translational and clinical research questions remain unanswered. In March 2018, an International Workshop on Merkel Cell Carcinoma Research was held at the US National Cancer Institute, at which academic, government and industry experts met to identify the highest-priority research questions. Here, we review the biology and treatment of MCC and report the consensus-based recommendations agreed upon during the workshop.

PMID- 30287940 TI - Humanization of Antibodies using a Statistical Inference Approach. AB - Antibody humanization is a key step in the preclinical phase of the development of therapeutic antibodies, originally developed and tested in non-human models (most typically, in mouse). The standard technique of Complementarity-Determining Regions (CDR) grafting into human Framework Regions of germline sequences has some important drawbacks, in that the resulting sequences often need further back mutations to ensure functionality and/or stability. Here we propose a new method to characterize the statistical distribution of the sequences of the variable regions of human antibodies, that takes into account phenotypical correlations between pairs of residues, both within and between chains. We define a "humanness score" of a sequence, comparing its performance in distinguishing human from murine sequences, with that of some alternative scores in the literature. We also compare the score with the experimental immunogenicity of clinically used antibodies. Finally, we use the humanness score as an optimization function and perform a search in the sequence space, starting from different murine sequences and keeping the CDR regions unchanged. Our results show that our humanness score outperforms other methods in sequence classification, and the optimization protocol is able to generate humanized sequences that are recognized as human by standard homology modelling tools. PMID- 30287941 TI - The Long-term Outcome After Resection of Upper Cervical Spinal Cord Tumors: Report of 51 Consecutive Cases. AB - The literature discussing the long-term outcome after resection of upper cervical spinal cord tumors is limited. The purpose of this study was to review the progression-free survival (PFS), overall survival (OS), and long-term outcomes in a consecutive series of 51 patients with upper cervical spinal cord tumors who underwent surgery at our institution between 2005 and 2010. Patient outcome were evaluated using the Japanese Orthopaedic Association score (JOA) and the McCormick functional schema. Follow-up data was collected completely and the median follow-up time was 6.1 years. Gross total resection (GTR) was performed in 27 patients (52.94%) and subtotal resection (STR) in 24 patients (47.06%). Progression-free survival and overall survival at 5 years was 88.23% and 92.16%, respectively. Good prognosis was defined as 74.51% based on JOA scoring. The univariate analysis showed that patients over 60y, tumors located higher than C2, tumor size greater than 4 cm as well as malignant tumors and subtotal resection were factors indicating a poor prognosis. However, the multivariate regression analyses showed only the level of tumor and tumor size were independent risk factors for a poor prognosis. The gold standard treatment for intraspinal tumors is gross total resection and follow-up should be focused on patients with a high risk of poor prognosis. PMID- 30287942 TI - Tom20 senses iron-activated ROS signaling to promote melanoma cell pyroptosis. AB - Iron has been shown to trigger oxidative stress by elevating reactive oxygen species (ROS) and to participate in different modes of cell death, such as ferroptosis, apoptosis and necroptosis. However, whether iron-elevated ROS is also linked to pyroptosis has not been reported. Here, we demonstrate that iron activated ROS can induce pyroptosis via a Tom20-Bax-caspase-GSDME pathway. In melanoma cells, iron enhanced ROS signaling initiated by CCCP, causing the oxidation and oligomerization of the mitochondrial outer membrane protein Tom20. Bax is recruited to mitochondria by oxidized Tom20, which facilitates cytochrome c release to cytosol to activate caspase-3, eventually triggering pyroptotic death by inducing GSDME cleavage. Therefore, ROS acts as a causative factor and Tom20 senses ROS signaling for iron-driven pyroptotic death of melanoma cells. Since iron activates ROS for GSDME-dependent pyroptosis induction and melanoma cells specifically express a high level of GSDME, iron may be a potential candidate for melanoma therapy. Based on the functional mechanism of iron shown above, we further demonstrate that iron supplementation at a dosage used in iron deficient patients is sufficient to maximize the anti-tumor effect of clinical ROS-inducing drugs to inhibit xenograft tumor growth and metastasis of melanoma cells through GSDME-dependent pyroptosis. Moreover, no obvious side effects are observed in the normal tissues and organs of mice during the combined treatment of clinical drugs and iron. This study not only identifies iron as a sensitizer amplifying ROS signaling to drive pyroptosis, but also implicates a novel iron based intervention strategy for melanoma therapy.

AB - In the version of this Article originally published, in the first paragraph of the Methods, HFE was incorrectly given as 2,2,2-Trifluoroethyl-3',3',3',2',2' pentafluoropropyl ether; it should have been 1,1,2,2-tetrafluoroethyl-2',2',2' trifluoroethyl ether. This has now been corrected in the online versions of the Article. PMID- 30287943 TI - Conscious processing of auditory regularities induces a pupil dilation. AB - Pupil dilation has been reliably identified as a physiological marker of consciously reportable mental effort. This classical finding raises the question of whether or not pupil dilation could be a specific somatic signature of conscious processing. In order to explore this possibility, we engaged healthy volunteers in the 'local global' auditory paradigm we previously designed to disentangle conscious from non-conscious processing of novelty. We discovered that consciously reported violations of global (inter-trials) regularity were associated with a pupil dilation effect both in an active counting task and in a passive attentive task. This pupil dilation effect was detectable both at the group-level and at the individual level. In contrast, unreported violations of this global regularity, as well as unreported violations of local (intra-trial) regularity that do not require conscious access, were not associated with a pupil dilation effect. We replicated these findings in a phonemic version of the 'local global'. Taken together these results strongly suggest that pupil dilation is a somatic marker of conscious access in the auditory modality, and that it could therefore be used to easily probe conscious processing at the individual level without interfering with participant's stream of consciousness by questioning him/her. PMID- 30287945 TI - Notch and interacting signalling pathways in cardiac development, disease, and regeneration. AB - Cardiogenesis is a complex developmental process involving multiple overlapping stages of cell fate specification, proliferation, differentiation, and morphogenesis. Precise spatiotemporal coordination between the different cardiogenic processes is ensured by intercellular signalling crosstalk and tissue tissue interactions. Notch is an intercellular signalling pathway crucial for cell fate decisions during multicellular organismal development and is aptly positioned to coordinate the complex signalling crosstalk required for progressive cell lineage restriction during cardiogenesis. In this Review, we describe the role of Notch signalling and the crosstalk with other signalling pathways during the differentiation and patterning of the different cardiac tissues and in cardiac valve and ventricular chamber development. We examine how perturbation of Notch signalling activity is linked to congenital heart diseases affecting the neonate and adult, and discuss studies that shed light on the role of Notch signalling in heart regeneration and repair after injury. PMID- 30287946 TI - The role of adipose tissue in cardiovascular health and disease. AB - Accumulating knowledge on the biology and function of the adipose tissue has led to a major shift in our understanding of its role in health and disease. The adipose tissue is now recognized as a crucial regulator of cardiovascular health, mediated by the secretion of several bioactive products, including adipocytokines, microvesicles and gaseous messengers, with a wide range of endocrine and paracrine effects on the cardiovascular system. The adipose tissue function and secretome are tightly controlled by complex homeostatic mechanisms and local cell-cell interactions, which can become dysregulated in obesity. Systemic or local inflammation and insulin resistance lead to a shift in the adipose tissue secretome from anti-inflammatory and anti-atherogenic towards a pro-inflammatory and pro-atherogenic profile. Moreover, the interplay between the adipose tissue and the cardiovascular system is bidirectional, with vascular derived and heart-derived signals directly affecting adipose tissue biology. In this Review, we summarize the current knowledge of the biology and regional variability of adipose tissue in humans, deciphering the complex molecular mechanisms controlling the crosstalk between the adipose tissue and the cardiovascular system, and their possible clinical translation. In addition, we highlight the latest developments in adipose tissue imaging for cardiovascular risk stratification and discuss how therapeutic targeting of the adipose tissue can improve prevention and treatment of cardiovascular disease.

PMID- 30287949 TI - Overexpression of Rubisco subunits with RAF1 increases Rubisco content in maize. AB - Rubisco catalyses a rate-limiting step in photosynthesis and has long been a target for improvement due to its slow turnover rate. An alternative to modifying catalytic properties of Rubisco is to increase its abundance within C4 plant chloroplasts, which might increase activity and confer a higher carbon assimilation rate. Here, we overexpress the Rubisco large (LS) and small (SS) subunits with the Rubisco assembly chaperone RUBISCO ASSEMBLY FACTOR 1 (RAF1). While overexpression of LS and/or SS had no discernable impact on Rubisco content, addition of RAF1 overexpression resulted in a >30% increase in Rubisco content. Gas exchange showed a 15% increase in CO2 assimilation (ASAT) in UBI LSSS-RAF1 transgenic plants, which correlated with increased fresh weight and in vitro Vcmax calculations. The divergence of Rubisco content and assimilation could be accounted for by the Rubisco activation state, which decreased up to 23%, suggesting that Rubisco activase may be limiting Vcmax, and impinging on the realization of photosynthetic potential from increased Rubisco content. PMID- 30287950 TI - Bias in resistance gene prediction due to repeat masking. AB - Several recently published Brassicaceae genome annotations show strong differences in resistance (R)-gene content. We believe that this is caused by different approaches to repeat masking. Here we show that some of the repeats stored in public databases used for repeat masking carry pieces of predicted R gene-related domains, and demonstrate that at least some of the variance in R gene content in recent genome annotations is caused by using these repeats for repeat masking. We also show that other classes of genes are less affected by this phenomenon, and estimate a false positive rate of R genes (0 to 4.6%) that are in reality transposons carrying the R-gene domains. These results may partially explain why there has been a decrease in published novel R genes in recent years, which has implications for plant breeding, especially in the face of pathogens changing as a response to climate change.

AB - BRZ-INSENSITIVE-LONG HYPOCOTYL 1 (BIL1)/BRASSINAZOLE-RESISTANT 1 (BZR1) is a master transcription factor of brassinosteroid (BR) signalling. The varieties of nucleobase recognition of the NN-BRRE-core motif (NNCGTG), one of variant G-box motifs, distinguish BIL1/BZR1 from basic helix-loop-helix transcription factors, underlying the specific regulation of BR-responsive genes. Here, we show the non canonical bHLH dimer formation of BIL1/BZR1 to optimize the interaction network with DNA and the orientation of a key residue for NN-BRRE-core motif recognition.

PMID- 30287954 TI - Complete substitution of a secondary cell wall with a primary cell wall in Arabidopsis. AB - The bulk of a plant's biomass, termed secondary cell walls, accumulates in woody xylem tissues and is largely recalcitrant to biochemical degradation and saccharification1. By contrast, primary cell walls, which are chemically distinct, flexible and generally unlignified2, are easier to deconstruct. Thus, engineering certain primary wall characteristics into xylem secondary walls would be interesting to readily exploit biomass for industrial processing. Here, we demonstrated that by expressing AP2/ERF transcription factors from group IIId and IIIe in xylem fibre cells of mutants lacking secondary walls, we could generate plants with thickened cell wall characteristics of primary cell walls in the place of secondary cell walls. These unique, newly formed walls displayed physicochemical and ultrastructural features consistent with primary walls and had gene expression profiles illustrative of primary wall synthesis. These data indicate that the group IIId and IIIe AP2/ERFs are transcription factors regulating primary cell wall deposition and could form the foundation for exchanging one cell wall type for another in plants.

AB - Genome editing holds great promise for increasing crop productivity, and there is particular interest in advancing breeding in orphan crops, which are often burdened by undesirable characteristics resembling wild relatives. We developed genomic resources and efficient transformation in the orphan Solanaceae crop 'groundcherry' (Physalis pruinosa) and used clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein-9 nuclease (Cas9) (CRISPR Cas9) to mutate orthologues of tomato domestication and improvement genes that control plant architecture, flower production and fruit size, thereby improving these major productivity traits. Thus, translating knowledge from model crops enables rapid creation of targeted allelic diversity and novel breeding germplasm in distantly related orphan crops.

AB - Patients presenting with flabby or displaceable tissue continue to challenge even the most competent dental practitioners. Under compression, the denture bearing area will exhibit localised mobility around the flabby tissue. Selective impression techniques have long been used in such cases, ensuring the displaceable tissue is recorded 'at rest'. Subsequently, the denture will maintain its peripheral seal during function. This article will describe five steps in maximising the success when producing a retentive and stable removable prosthesis for flabby ridges.

PMID- 30287965 TI - Interviews and focus groups in qualitative research: an update for the digital age. AB - Qualitative research is used increasingly in dentistry, due to its potential to provide meaningful, in-depth insights into participants' experiences, perspectives, beliefs and behaviours. These insights can subsequently help to inform developments in dental practice and further related research. The most common methods of data collection used in qualitative research are interviews and focus groups. While these are primarily conducted face-to-face, the ongoing evolution of digital technologies, such as video chat and online forums, has further transformed these methods of data collection. This paper therefore discusses interviews and focus groups in detail, outlines how they can be used in practice, how digital technologies can further inform the data collection process, and what these methods can offer dentistry. PMID- 30287963 TI - Molar incisor hypomineralisation (MIH) - an overview. AB - Recent data indicates that molar-incisor hypomineralisation (MIH) is a frequently - encountered dental condition worldwide. The condition could be associated with dental complications that might affect patients' quality of life as well as create treatment challenges to dentists. The affected teeth are more prone to caries and post-eruptive enamel breakdown, therefore, it is believed that this condition might be responsible for a substantial proportion of childhood caries since the condition has high prevalence. MIH is common, and as such it should be diagnosed and managed in primary care wherever possible. Early diagnosis can lead to more effective and conservative management. This article aims to highlight different aspects related to MIH, from its prevalence to treatment options in young patients.

PMID- 30287970 TI - PCA in High Dimensions: An orientation. AB - When the data are high dimensional, widely used multivariate statistical methods such as principal component analysis can behave in unexpected ways. In settings where the dimension of the observations is comparable to the sample size, upward bias in sample eigenvalues and inconsistency of sample eigenvectors are among the most notable phenomena that appear. These phenomena, and the limiting behavior of the rescaled extreme sample eigenvalues, have recently been investigated in detail under the spiked covariance model. The behavior of the bulk of the sample eigenvalues under weak distributional assumptions on the observations has been described. These results have been exploited to develop new estimation and hypothesis testing methods for the population covariance matrix. Furthermore, partly in response to these phenomena, alternative classes of estimation procedures have been developed by exploiting sparsity of the eigenvectors or the covariance matrix. This paper gives an orientation to these areas. PMID- 30287971 TI - Choosing a Control Group for Displaced Workers. AB - The vast majority of studies on the earnings of displaced workers use a control group of never displaced workers to examine the effects of initial displacements. This approach attributes earnings declines due to all future job instability to the initial displacement event, overstating the losses relative to the average treatment effect. This paper's approach isolates the impact of an average displacement without conditioning on future displacement status in the control group. In comparisons of the standard and alternative approaches using PSID data, the estimated long-run earnings losses fall dramatically from 25 percent to as low as 5 percent.

AB - Family instability means that many U.S. youth spend time without biological fathers and with other men. This study extends the literature on the developmental implications of living with fathers and father figures by investigating the association between the presence of mothers' male romantic partners in the home and secondary exposure to violence with a focus on variability according to the identities of the men and the communities of the family. Fixed effects models of multilevel data from the Project on Human Development in Chicago Neighborhoods (n = 2,201) revealed that living with mothers' partners did not have a general protective or risky association with youths' secondary exposure to violence. This exposure, however, was lower when such men were youths' biological fathers (vs. social fathers) and when they were married to (vs. cohabiting with) youths' mothers. The link between men's marital status and exposure to violence appeared stronger in higher-crime neighborhoods. PMID- 30287973 TI - Research and Education in Computational Science and Engineering. AB - This report presents challenges, opportunities and directions for computational science and engineering (CSE) research and education for the next decade. Over the past two decades the field of CSE has penetrated both basic and applied research in academia, industry, and laboratories to advance discovery, optimize systems, support decision-makers, and educate the scientific and engineering workforce. Informed by centuries of theory and experiment, CSE performs computational experiments to answer questions that neither theory nor experiment alone is equipped to answer. CSE provides scientists and engineers with algorithmic inventions and software systems that transcend disciplines and scales. CSE brings the power of parallelism to bear on troves of data. Mathematics-based advanced computing has become a prevalent means of discovery and innovation in essentially all areas of science, engineering, technology, and society; and the CSE community is at the core of this transformation. However, a combination of disruptive developments-including the architectural complexity of extreme-scale computing, the data revolution and increased attention to data driven discovery, and the specialization required to follow the applications to new frontiers-is redefining the scope and reach of the CSE endeavor. With these many current and expanding opportunities for the CSE field, there is a growing demand for CSE graduates and a need to expand CSE educational offerings. This need includes CSE programs at both the undergraduate and graduate levels, as well as continuing education and professional development programs, exploiting the synergy between computational science and data science. Yet, as institutions consider new and evolving educational programs, it is essential to consider the broader research challenges and opportunities that provide the context for CSE education and workforce development.

AB - This paper discusses the challenges presented by tall data problems associated with Bayesian classification (specifically binary classification) and the existing methods to handle them. Current methods include parallelizing the likelihood, subsampling, and consensus Monte Carlo. A new method based on the two stage Metropolis-Hastings algorithm is also proposed. The purpose of this algorithm is to reduce the exact likelihood computational cost in the tall data situation. In the first stage, a new proposal is tested by the approximate likelihood based model. The full likelihood based posterior computation will be conducted only if the proposal passes the first stage screening. Furthermore, this method can be adopted into the consensus Monte Carlo framework. The two stage method is applied to logistic regression, hierarchical logistic regression, and Bayesian multivariate adaptive regression splines. PMID- 30287976 TI - Multi-level Supervision and Modification of Artificial Pancreas Control System. AB - Artificial pancreas (AP) systems provide automated regulation of blood glucose concentration (BGC) for people with type 1 diabetes (T1D). An AP includes three components: a continuous glucose monitoring (CGM) sensor, a controller calculating insulin infusion rate based on the CGM signal, and a pump delivering the insulin amount calculated by the controller to the patient. The performance of the AP system depends on successful operation of these three components. Many APs use model predictive controllers that rely on models to predict BGC and to calculate the optimal insulin infusion rate. The performance of model-based controllers depends on the accuracy of the models that is affected by large dynamic changes in glucose-insulin metabolism or equipment performance that may move the operating conditions away from those used in developing the models and designing the control system. Sensor errors and missing signals will cause calculation of erroneous insulin infusion rates. And the performance of the controller may vary at each sampling step and each period (meal, exercise, and sleep), and from day to day. Here we describe a multi-level supervision and controller modification (ML-SCM) module is developed to supervise the performance of the AP system and retune the controller. It supervises AP performance in 3 time windows: sample level, period level, and day level. At sample level, an online controller performance assessment sub-module will generate controller performance indexes to evaluate various components of the AP system and conservatively modify the controller. A sensor error detection and signal reconciliation module will detect sensor error and reconcile the CGM sensor signal at each sample. At period level, the controller performance is evaluated with information collected during a certain time period and the controller is tuned more aggressively. At the day level, the daily CGM ranges are further analyzed to determine the adjustable range of controller parameters used for sample level and period level. Thirty subjects in the UVa/Padova metabolic simulator were used to evaluate the performance of the ML-SCM module and one clinical experiment is used to illustrate its performance in a clinical environment. The results indicate that the AP system with an ML-SCM module has a safer range of glucose concentration distribution and more appropriate insulin infusion rate suggestions than an AP system without the ML-SCM module.

In South Africa, school dropout is a crisis where by Grade 12, only 52% of the age appropriate population remain enrolled. Survival analysis was used to identify the risk of dropping out of secondary school for male and female adolescents and examine the influence of substance use and leisure experience predictors while controlling for demographic and known predictors using secondary, longitudinal data. Results indicated being male, not living with one's mother, smoking cigarettes in the past month, and lower levels of leisure-related intrinsic motivation significantly predicted dropout. Results support comprehensive prevention programmes that target risk behaviour and leisure. PMID- 30287978 TI - Neonatal Micro-RNA Profile Determines Endothelial Function in Offspring of Hypertensive Pregnancies. AB - Offspring of hypertensive pregnancies are at increased risk of developing hypertension in adulthood. In the neonatal period they display endothelial cell dysfunction and altered microvascular development. MicroRNAs, as important endothelial cellular regulators, may play a role in this early endothelial dysfunction. Therefore we identified differential microRNA patterns in endothelial cells from offspring of hypertensive pregnancies and determined their role in postnatal vascular cell function. Studies were performed on human umbilical vein endothelial cell (HUVECs) samples from 57 pregnancies. Unbiased RNA-sequencing identified 30 endothelial-related microRNAs differentially expressed in HUVECs from hypertensive compared to normotensive pregnancies. Quantitative reverse transcription PCR (RT-qPCR) confirmed a significant higher expression level of the top candidate, miR-146a. Combined miR-146a targeted gene expression and pathway analysis revealed significant alterations in genes involved in inflammation, angiogenesis and immune response in the same HUVECs. Elevated miR-146a expression level at birth identified cells with reduced ability for in vitro vascular tube formation, which was rescued by miR-146a inhibition. In contrast, miR-146a overexpression significantly reduced vascular tube formation in HUVECs from normotensive pregnancies. Finally, we confirmed that mir146a levels at birth predicted in vivo microvascular development during the first three postnatal months. Offspring of hypertensive pregnancy have a distinct endothelial regulatory microRNA profile at birth, which is related to altered endothelial cell behaviour, and predicts patterns of microvascular development during the first three months of life. Modification of this microRNA profile in vitro can restore impaired vascular cell function. PMID- 30287980 TI - Locally optimal designs for some binary dose-response models. AB - In this paper, we consider the problem of seeking locally optimal designs for nonlinear dose-response models with binary outcomes. Applying the theory of Tchebycheff Systems and other algebraic tools, we show that the locally D-, A-, and c-optimal designs for three binary dose-response models are minimally supported in finite, closed design intervals. The methods to obtain such designs are presented along with examples. The efficiencies of these designs are also discussed. PMID- 30287982 TI - A Discrete-Time Branching Process Model of Yeast Prion Curing Curves. AB - The infectious agent of many neurodegenerative disorders is thought to be aggregates of prion protein, which are transmitted between cells. Recent work in yeast supports this hypothesis, but suggests that only aggregates below a critical size are transmitted efficiently. The total number of transmissible aggregates in a typical cell is a key determinant of strain infectivity. In a discrete-time branching process model of a yeast colony with prions, prion aggregates increase in size according to a Poisson process and only aggregates below a threshold size are transmitted during cell division. The total number of cells with aggregates in a growing population of yeast is expressed. PMID- 30287983 TI - Botanical Integrity: The Importance of the Integration of Chemical, Biological, and Botanical Analyses, and the Role of DNA Barcoding. AB - Raw materials, ingredients, and products derived from plants are commonly referred to as herbs or botanicals in both the biomedical literature and the natural products health industry. This overarching term includes the breadth of crude herbs, plant parts, and the ingredients made from them, and also covers finished products such as botanical dietary supplements. Botanical dietary supplements are intended to supplement the human diet and are composed primarily of powdered plant parts, their extracts, or other preparations derived from crude herbal material; some formulations include other ingredients such as vitamins, minerals, and amino acids. Botanical dietary supplements are highly complex mixtures reflecting the diverse chemical constituents that comprise the source plant's raw material. Botanical analysis is an intricate analytical challenge requiring specialized skills and instrumentation that is different from those required for quality control of chemically simpler pharmaceuticals, or for the safety assessment of many conventional food or other products that are generally regarded as safe (GRAS). PMID- 30287981 TI - Social Problems in ADHD: Is it a Skills Acquisition or Performance Problem? AB - Recent models suggest that social skills training's inefficacy for children with ADHD may be due to target misspecification, such that their social problems reflect inconsistent performance rather than knowledge/skill gaps. No study to date, however, has disentangled social skills acquisition from performance deficits in children with ADHD. Children ages 8-12 with ADHD (n=47) and without ADHD (n=23) were assessed using the well-validated social behavioral analysis framework to quantify cross-informant social skills acquisition deficits, performance deficits, and strengths. Results provided support for the construct and predictive validities of this Social Skills Improvement System (SSIS) alternate scoring method, including expected magnitude and valence relations with BASC-2 social skills and ADHD symptoms based on both parent and teacher report. Acquisition deficits were relatively rare and idiosyncratic for both the ADHD and Non-ADHD groups, whereas children with ADHD demonstrated cross-informant social performance deficits (d=0.82-0.99) on several specific behaviors involving attention to peer directives, emotion regulation, and social reciprocity. Relative to themselves, children with ADHD were perceived by parents and teachers as exhibiting more social strengths than social acquisition deficits; however, they demonstrated significantly fewer social strengths than the Non-ADHD group (d = -0.71 to -0.89). These findings are consistent with recent conceptualizations suggesting that social problems in ADHD primarily reflect inconsistent performance rather than a lack of social knowledge/skills. Implications for refining social skills interventions for ADHD are discussed. PMID- 30287984 TI - Botanical Integrity: Part 2: Traditional and Modern Analytical Approaches.

AB - Breast cancer in India appears to be diagnosed more in the young women, but whether this is an actual higher incidence, and hence a matter of concern, needs more clarity, and the extent to which correctable measures can be taken to reduce or overcome this additional disease burden, if any, has to be better understood. The article analyzes these and more in a systematic manner and highlights the important issues in the very young women which makes the clinical management of breast cancer more complex. PMID- 30287987 TI - Oncologic and Cosmetic Outcomes of Oncoplastic Breast Surgery in Locally Advanced Breast Cancer After Neoadjuvant Chemotherapy, Experience from a Developing Country. AB - Oncoplastic surgery (OPS) has emerged as a new approach for extending breast conserving surgery (BCS) possibilities, reducing both mastectomy and re-excision rates, while avoiding breast deformities. OPS is based upon the integration of plastic surgery techniques for immediate reshaping after wide excision for breast cancer. This is a prospective feasibility cohort study of oncoplastic breast surgery after neoadjuvant chemotherapy that was carried at the National Cancer Institute, Cairo University and included 70 patients. The primary outcome was the local recurrence rate. Secondary outcomes included survival and margins obtained as well as cosmetic outcomes. Survival analysis was performed. Oncoplastic breast surgery did not compromise oncologic safety in the patients included in the study. It even allowed wider margins of resection which could be associated with better oncologic outcomes. At the same time, it gave a better cosmetic outcome and therefore higher patient satisfaction. Oncoplastic breast surgery includes a wide spectrum of surgical techniques, ranging from the basic level I techniques in breast conserving surgery to the more complex procedures of level II which are broadly classified into volume replacement (therapeutic mammoplasty) and volume displacement procedures. We suggest that oncoplastic breast surgery techniques should be the standard of care in breast surgery. They are the basis for breast conserving surgery techniques in early breast cancer. In our experience, oncoplastic surgery is feasible in locally advanced tumours after downstaging with neoadjuvant chemotherapy without compromising the oncologic safety. PMID- 30287988 TI - Role of Plasma D-Dimer Levels in Breast Cancer Patients and Its Correlation with Clinical and Histopathological Stage. AB - Breast cancer, the most common female malignancy, represents a heterogeneous group of tumors, which presen both varied behaviors and response to therapy. This study was done with an attempt to evaluate the role of D-dimer in patients of carcinoma breast, in predicting lymph node metastasis in carcinoma patients and to look for relationship of these markers with histopathologic parameters. Clinical data was obtained from clinical examination of patients admitted in the Department of Surgery with history of breast lump and confirmed with fine needle aspiration cytology (FNAC). Clinical staging was done using TNM staging. D-dimer level was measured prior to commencement of treatment, i.e., modified radical mastectomy (MRM) or neoadjuvant chemotherapy and finally 6 months after surgery or completion of 6 cycles of chemotherapy. The characteristics of the study population Out of 60 study cases minimum age of the patient being 30 years and maximum being 74 years. Of all histopathologic variables examined, D-dimer levels directly correlated with extent of lymph node involvement and lymphovascular invasion, D-dimer levels correlated strongest with the number of positive lymph nodes, but not with tumor size, estrogen receptor status, and progesterone receptor status. This study clearly shows that plasma D-Dimer levels are elevated in carcinoma breast patients. Increased D-Dimer levels are an important marker of clinical stage, lymphovascular invasion, lymph node involvement, and tumor metastasis. PMID- 30287989 TI - Quality Indicators for Sentinel Lymph Node Biopsy in Breast Cancer: Applicability and Clinical Relevance in a Non-screened Population. AB - Quality Indicators for Sentinel Lymph Node Biopsy in Breast Cancer: Applicability and Clinical Relevance in a Non-screened Population: sentinel lymph node biopsy (SLNB) has replaced axillary lymph node dissection (ALND) as standard of care for management of early breast cancer. This study assessed our SLNB program against 11 published quality indicators (QIs). All breast cancer patients who underwent SLNB in our centre from June 2013-Dec 2015 were included. Clinical, pathological and follow-up data were extracted from the institutional REDCap data system. Analysis was done with SPSS 23. Following validation, 234 patients had SLNB, always performed along with primary surgery. Identification rate was 95.3% and > 1 SLN was identified in 72% of patients. SLNB positivity was 33%, of these, 100% underwent ALND. Overall 91% of QI eligible patients underwent SLNB. No ineligible patients (T4) underwent SLNB. For the patients who had radio colloid, injection criteria were met for 100%. Pathological evaluation and reporting criteria were met for 100% of patients. There were no axillary recurrences in a median follow up of 2 years. 7.6% patients had SLN negative on frozen section but positive on final histology. 7.2% of patients with clinical negative nodes had pN2 disease in final histopathology report after surgery. Sixty percent of patients who had completion ALND had only positive SLN. This study supports the applicability of published QI of SLNB in a non-screened cohort of early breast cancer patients. Although QI were useful, modification based on patient characteristics and resource availability may be needed. These indicators can be used as audit tools to improve the overall accuracy of the procedure.

AB - Breast cancer (BC) has become the most common cancer in urban women. Unfortunately, most women are not aware of BC symptoms/signs, prevention, and management. In resource-limited countries like India where we do not have structured screening/awareness programs, a majority of women present with locally advanced BC. The aim of our study is to identify the present status of awareness about BC prevention, early detection, symptoms, and management in urban and rural Indian women (medical, paramedical, and nonmedical) and to assess whether education and socioeconomic strata have any role in better awareness about BC or not. We did a prospective cross-sectional observation study among the medical, paramedical, and nonmedical women in the northern part of India. We designed a questionnaire keeping in mind the three domains about BC-knowledge (questions 1 25 include risk factors, genetics, lifestyle changes, hormones, associated cancers, and modes of presentation like lump, nipple/skin changes), breast self examination (questions 25-37), and attitude to prevention and early detection (questions 38-44). We also asked how many do breast self-examination (BSE) and what they think are the three main factors responsible for late presentation and the three main ways to increase BC awareness. The Likert scale was used for objective assessment. We analyzed the whole data using SPSS software version 15. A total of 220 women out of 270 completed the questionnaire. Out of 220 women, 26.4% were medical, 20.9% paramedical, and 52.7% nonmedical. Most women were educated (82.7%) and married (65%). 59.5% women resided in urban areas and the rest (40.5%) were from rural areas. We found that there was relatively more knowledge in the medical group; however, the skills of BSE and attitude to prevention and early detection in all the three subgroups and among rural and urban women were suboptimal and not different significantly. The three main factors responsible for delayed presentation were shyness and not knowing BSE, ignorance about BC symptoms, and social stigma of cancer along with financial constraints. The three main ways to improve BC awareness suggested were to have more advertisements on television and social media, roadside campaigns and in colleges along with group discussions and debates, and at grassroots level to involve Anganwadi workers and nurses to create more awareness in villages. There was less breast cancer knowledge and awareness among the nonmedical women compared to those among the medical and paramedical, the skills of BSE and attitude to prevention and early detection were suboptimal in all the three groups. Rural or urban dwellings did not make much difference in BC knowledge, skills of BSE, and attitude to prevention. More awareness regarding breast cancer symptoms with early detection and BSE need to be addressed with more information dissemination via social media, campaigns, and involvement of paramedics and social workers. PMID- 30287992 TI - Unusual Breast Neoplasm with Diagnostic and Management Challenges. AB - With the growing awareness and availability of proper screening methods, detection of breast lump is increasing globally and is now a very sensitive issue for females. The treatment of these lumps ranges from lumpectomy to wide local excision to mastectomy; hence, a proper diagnosis is very important to prevent under- or overtreatment in patients. Breast lesions are the heterogeneous diseases encompassing several distinct entities with remarkably different characteristics. While the more common forms of breast cancers are well recognized and understood better, there are many important unusual lesions and malignancies that are less known and less appreciated and can be challenging to diagnose. In such cases, due to rarity of the disease and lack of adequate treatment protocol, managing the patients can be a challenging task for surgeons and oncologist as well. In this article, we have shared our institutional experience in unusual breast lesions with emphasis on diagnostic as well as management challenges faced. PMID- 30287993 TI - Stridor as the First Presentation of Metastatic Breast Cancer that Was Managed with Chemotherapy: a Case Report. AB - Supraclavicular nodal metastases of breast cancer are rare and occur in about 8% of newly diagnosed cases. It is rarely discussed in the literature that breast cancer was metastasizing to higher levels of the cervical nodes. We report a case of metastatic breast cancer to the deep cervical lymph nodes that caused stridor due to compression of the recurrent laryngeal nerve which was diagnosed by indirect laryngoscopy. After full investigations, urgent chemotherapy was started and it showed a dramatic response with disappearance of the lymph node after two cycles with resolution of the stridor. This report also highlights the association of other metastatic sites with this higher level of neck nodal metastases of breast cancer. PMID- 30287994 TI - Rare Case Report of Neuroendocrine Tumor in Axilla-Metastasis from Unknown Primary or De Novo? AB - Neuroendocrine tumors (NET) are the neoplasm arising from neuroendocrine cells which are present throughout the body. It can be benign, being more common or malignant. Gut is the most common site, but they can be seen in any part of the body. We had a case of grade III NET in axilla presented with a fungating lesion with unknown primary. Clinical behavior of such tumor is predicted by tumor grade or differentiation. We treated this patient by surgery and adjuvant chemotherapy. PMID- 30287995 TI - Nipple Areola Complex Involvement in Invasive Carcinoma Breast. AB - A variety of factors including tumor biology and distance of the tumor from the nipple have been associated with nipple areola complex involvement in patients with breast cancer. Preoperative understanding regarding these factors can help in modifying the surgical options including preservation of nipple areola complex (NAC) and breast conservation. Nipple sparing surgery (breast conservation surgery/skin sparing mastectomy with immediate reconstruction) for breast cancer has gained widespread interest with the aim of achieving oncologically safe and cosmetically acceptable outcome. To study the proportion of cases with nipple areola complex involvement in invasive carcinoma breast and to describe the variables predictive of nipple areola complex involvement in patients undergoing excision of tumor along with NAC for invasive carcinoma breast. A cross-sectional study was conducted among 136 patients who underwent mastectomy in Regional Cancer Center, Thiruvananthapuram. Tumor nipple distance was assessed preoperatively using mammogram and postoperatively by histopathological examination. Nipple involvement was seen only among 4.4%. Preoperative assessment of tumor to nipple distance, tumor size, location, and stage of the disease agrees with the histopathological examination. Only a small proportion of breast cancer has NAC involvement and preoperative assessment could help the surgeon in deciding on the feasibility of NAC preservation. PMID- 30287996 TI - Bilateral Breast and Axillary Lymph Nodes Metastases of an Ovarian Serous Cystadenocarcinoma. PMID- 30287997 TI - Dermatofibrosarcoma Protuberans of the Breast-a Rare Entity. AB - Dermatofibrosarcoma protuberans (DFSP) represents about 1% of soft-tissue sarcomas with an estimated incidence of 0.8 to 5.0 cases per million per year. This lesion may occur anywhere in the body but more than 50% occur on the trunk, 20% on the head and neck and 30% on the extremities. DFSP of the breast is an extremely uncommon site of presentation. Data regarding DFSP of the breast is limited and mostly in the form of case reports. Clinical presentation is not uniform and may mimic benign skin lesions [1]. However, it typically presents as a nodular cutaneous mass in early or mid-adult life. We herein report a case of DFSP of the breast in a 33-year-old lady who was managed successfully in our institute and review the literature associated with it. PMID- 30287998 TI - Identification of Sentinel Lymph Nodes Using Contrast-Enhanced Ultrasound in Breast Cancer. AB - Sentinel lymph node (SLN) biopsy has become the standard of care in axillary staging of breast cancer patients who are clinically node negative as it reduces the morbidity of axillary nodal dissection. SLN biopsy using blue dye and radioisotopes have high identification rates but its limitations include anaphylaxis, disposal of radioactive waste, and potential second surgery in up to 35% of patients who show nodal metastases on SLN biopsy. Contrast-enhanced ultrasound (CEUS) has the potential for SLNs to be identified without the aforementioned risks. CEUS involves the administration of intravenous contrast agents containing microbubbles of perfluorocarbon or nitrogen gas. The bubbles greatly affect ultrasound backscatter and increase vascular contrast in a similar manner to intravenous contrast agents used in CT and MRI. It is safe and easily performed with no requirement for ionizing radiation and no risk of nephrotoxicity. Microbubbles are taken up by lymph nodes when injected directly into tissues, including sub-areolar injection in the breast cancer patient. This method may prove valuable in patients with ductal carcinoma in situ, where operative SLN biopsy remains controversial, and in women undergoing prophylactic mastectomies for high risk. This technique may also have a role after neoadjuvant chemotherapy where frequently there is fibrosis in the treated SLNs. PMID- 30287999 TI - Reconstruction in Breast Conservation Therapy-Single Tertiary Care Institution Experience with 472 Patients. AB - Breast conservation therapy (BCT) is now internationally accepted treatment for early breast cancer. Despite of high incidence of carcinoma breast in India, BCT rates are very low as compared to the west. In this article, we wish to share our experience of breast conservation with oncoplasty in Indian women. A retrospective analysis of case records of patients treated with oncoplastic breast conservation from January 2009 to June 2014 in a single surgical oncology unit in a tertiary cancer institute. Demographic patient data, stage of disease, location of primary tumour, use of neo-adjuvant chemotherapy if received, tumour size and breast size ratio, reconstruction method used, post-operative complications and aesthetic score of patients were analysed. Various methods of oncoplasty and partial breast reconstruction used are discussed. Four hundred and seventy-two patient records were found suitable for analysis. Most common stage of presentation was T2N0 in 189 patients (40%). Forty-one patients received neo adjuvant chemotherapy (NACT). Tumour arising in upper outer quadrant was most common site, seen in 268 (56.7%). The most common method of reconstruction was volume displacement, done in 57.6% patients. Overall surgical complications included wound infection with or without dehiscence, seroma formation, partial flap necrosis and fat necrosis. Cosmesis was found to be excellent in 23.09% and good in 58.47% at 6-month follow-up. Breast conservation with oncoplasty is oncologically safe for early breast cancer treatment and has good cosmetic outcome with high patient satisfaction rates. Its practice should be encouraged in Indian set-up also. PMID- 30288000 TI - Lymphatic Microsurgical Preventing Healing Approach (LYMPHA) for Prevention of Breast Cancer-Related Lymphedema-a Preliminary Report. AB - Lymphatic microsurgical preventing healing approach (LYMPHA) for prevention of breast cancer-related lymphedema (BCRL)-a preliminary report BCRL-is a chronic debilitating condition which impairs quality of life of breast cancer survivors. The aim is to study the feasibility of preventing lymphedema by performing "Lymphatic Microsurgical Preventive Healing Approach (LYMPHA)." Patients undergoing breast cancer surgery with complete nodal dissection were taken up for the study. After the standard axillary nodal dissection, lymphatics were identified by the help of blue dye and were anastomosed with a tributary to the axillary vein. Post-operatively, patients were followed up clinically for development of lymphedema and lymphoscintigraphy was performed after treatment completion. A total of 35 patients were enrolled for the study. The average BMI was 29.5. LYMPHA was feasible in all cases. The number of lymphatics identified was 1 to 5 per axilla. Two patients developed transient lymphedema which resolved with conservative therapy and patients were able to discontinue the compression garment. Follow-up lymphoscintigraphy is performed in two patients, which showed normal lymphatic flow. LYMPHA is a feasible technique, not difficult to perform, takes a short time, is accomplished in same general anesthesia as for axillary dissection, and gives no extra scar. The early results are promising and long term follow-up may make the procedure as a routine. PMID- 30288001 TI - Patterns of Care of Breast Cancer Patients in a Rural Cancer Center in Western India. AB - Breast cancer is an emerging public health problem in low- and middle-income countries. The main objective is to describe the clinical characteristics and patterns of care of breast cancer patients diagnosed and treated in a rural cancer hospital in Barshi, Western India. The results from a cross-sectional study of 99 consecutive breast cancer patients diagnosed and treated between February 2012 and November 2014 in Nargis Dutt Memorial Cancer Hospital is reported. The case records of the patients were scrutinized and reviewed to abstract data on their clinical characteristics, diagnostic, and treatment details. The mean age at diagnosis of the patients was 52.8 +/- 11.6 years; 83.5% of women were married, and 60.6% were illiterate. Sixty percent of patients had tumors measuring 5 cm or less. Almost half of the patients (46.4%) had stage I or II A disease and a third (36.0%) had axillary lymph node metastasis. Estrogen, progesterone, and human epidermal growth factor receptor2 receptor status were investigated in 41 (41.4%) of patients only. The median interval between diagnosis and initiation of treatment was 11 days. Modified radical mastectomy was done in 91% of patients, and nearly a third of patients who were prescribed chemotherapy did not complete treatment. The rural-based tertiary cancer care center has made treatment more accessible to breast cancer patients and has reduced the interval between diagnosis and treatment initiation. However, there are still many challenges like non-compliance to and incomplete treatments and poor follow-up that need to be addressed. PMID- 30288003 TI - Malignant Spindle Cell Tumor Breast-a Diagnostic Dilemma. AB - Primary malignant spindle cell tumors are rare constituting 1.0% of breast malignancies. Spindle cell lesions occurring in soft tissues can occur in breast with overlapping morphologies. It can present as benign lesion and have inconclusive cytological findings, so easily missed if not properly dealt with. Stromal sarcoma should be diagnosed only after thorough sectioning and negative staining for p63, broad spectrum, and high molecular weight keratin. We present a case of right breast lump. Cytological features revealed fibro histiocytic lesion. There were no areas of necrosis, hemorrhage, or calcification. Histopathologically, it showed partially encapsulated tumor with cells arranged in sheets, composed of oval to epithelioid cells with spindling at places with moderate pleomorphism (mitotic activity 6-7/10 hpf). Differential diagnosis of primary stromal sarcoma, metaplastic sarcoma, and phyllodes was made. Immunohistochemistry revealed vimentin positivity with focal positivity of S-100. Desmin, cytokeratin and smooth muscle actin, p63, ER, PR, and Her2-neu were negative. A final diagnosis of primary breast sarcoma of neural origin was established with the help of histopathology and immunohistochemistry. To conclude, it is of utmost importance to identify primary stromal sarcomas as they are known to spread very rapidly and have a poor prognosis. PMID- 30288002 TI - Clinico-pathological Features of PIK3CA Mutation in HER2-Positive Breast Cancer of Indian Population. AB - PIK3CA pathway is one of the important signaling pathways in cells, which is involved in cell proliferation, cell survival, motility, and growth. Mutation in PIK3CA gene negatively effects to anti-HER2 therapy in breast cancer patients. PIK3CA gene of HER2-positive breast cancers associated with reduced sensitivity to neoadjuvant therapy. In this study, we assessed the frequency of PIK3CA mutations and influence of PIK3CA mutations on patient survival in a series of HER2-positive breast cancer patients. PIK3CA mutations were assessed by pyrosequencing and next generation sequencing in 107 HER2-positive breast cancer patients of a tertiary Cancer Centre of India from Jan 2012 to Jun 2013 with minimum follow-up of 3 years. We found PIK3CA mutations in 26 tumors (24.2%) of which 5 were in exon 9, 20 were in exon 20, and 1 was in both exon 9 and 20. In exon 9, the mutation c.1634A>G was found in 4 cases and mutation c.1636C>A was found in 2 cases. In exon 20, the mutation c.3140A>G was found in 15 cases and c.3140A>T was found in 6 cases. The outcome between PIK3CA mutated versus PIK3CA wild type was significant showing p value 0.014. Overall survival of mutation and treatment with herceptin, mutation with other chemotherapy treatment in both early breast cancer (EBC), and locally advanced breast cancer (LABC) showed significant p value 0.037 and 0.044 respectively. In conclusion, we identified 24.2% somatic mutation of PIK3CA in HER2-positive breast cancer patients. PIK3CA mutation is significantly associated with ER-positive tumors. The frequency and distribution pattern reported in this study is similar to the global report. Overall survival of PIK3CA mutation is slightly lower but in patients who received herceptin with PIK3CA mutation showed better clinical outcome. PMID- 30288004 TI - Numb Chin Syndrome as the Initial Manifestation of Breast Carcinoma. AB - Numb chin syndrome may be the manifestation of a local dental pathology or secondary to a systemic disease. A systematic physical examination with diagnostic workup is of utmost importance in patients presenting with numb chin syndrome. We report the case of a 58-year-old woman who presented with numb chin syndrome. An orthopantogram and computed tomography of the head revealed osteolytic lesion in the left molar region. Histopathological and immunohistochemical examination confirmed the lesion to be metastatic breast carcinoma. Breast ultrasound scan demonstrated a 1.5 * 1.5-cm lesion in the left breast and fine needle aspiration cytology from the lesion confirmed the diagnosis of breast carcinoma. Bone scan showed multiple bone metastases. She was diagnosed to have numb chin syndrome secondary to bone metastases from breast carcinoma. In view of her disseminated disease status, she was started on palliative hormone therapy (Letrozole) with zoledronic acid. We present this case to highlight the importance of careful evaluation of patients presenting with numb chin syndrome because this may be the only manifestation of a systemic malignancy. PMID- 30288005 TI - Extensive Re-ossification and Reformation of the Proximal Femur After External Beam Radiotherapy in Metastatic Carcinoma Breast. AB - Management of metastatic bone disease is still evolving and is dependent upon many factors including the primary tumour type, expected life expectancy, site and size of lesion, character of the lesion, lytic or blastic, and the number of lesions. Active orthopaedic surgical intervention is usually required at the time of pathological fracture either impending or actual. Management options are either in situ fixation or replacement/arthroplasty. The role of post-operative radiotherapy is still not clearly defined and its biological effect on healing of pathological fracture is unclear. In this report, we describe a case of breast carcinoma with a large metastatic lytic lesion in the proximal femur, which was treated by in situ fixation followed by hormonal therapy and external beam radiotherapy. In the post-operative period, rapid and dramatic ossification and reformation of the proximal femur was observed. PMID- 30288006 TI - Carcinosarcoma of Breast Mimicking Breast Abscess. AB - Carcinosarcoma, a tumor having both carcinomatous and sarcomatous elements, occurring in the breast, is a rare condition. The tumor consists of both epithelial and mesenchymal cell lines and tends to behave aggressively. It has clinical features like that of invasive breast carcinoma but sometimes there can be diagnostic confusion as it can mimic or present as breast abscess. Treatment is multimodal. Surgery plays the vital role. Post-op radiation and chemo are indicated. Hormone therapy is usually inapplicable as most of the time, it is hormone receptor negative. PMID- 30288007 TI - A Prospective Observational Study of Breast Lumps in Adolescent Girls: Tertiary Care South Indian Teaching Hospital Experience. AB - The aim of the current study was to assess the incidence and varying clinical presentations of benign breast lumps in adolescent age group in a Tertiary care Medical College Hospital. This was a prospective, observational study of 6-year duration (2011 to 2017) conducted in a Medical College, South India. All adolescent age group patients visiting the outpatient department (OPD) with complaints of breast lump were enrolled into the study. Triple assessment comprising of clinical examination, imaging, and core biopsy was used for diagnosis and identification of type of tumor. Management of tumors was based on pathology of core biopsy. During the study duration (2011 to 2017), a total of 15 pediatric patients of age between 11 to 14 years, presented with complaints of breast lumps. The most common symptom included painless lump in breast in 11 patients (73.34%). The histopathological examination (HPE) reported 12 cases (80%) as fibroadenomas and only 3 cases (20%) were phyllodes tumors. Based on the results of HPE, majority of the patients (53.34%) underwent circumareolar cosmetic incision. The most common lesions in pediatric age group are benign fibroadenomas; however, phyllodes are also not rare, and to manage them appropriately, they should be diagnosed preoperatively with core biopsy. Cases of malignancy, including phyllodes tumors, ductal adenocarcinomas, and metastatic lesions, have been documented in children and adolescents. Therefore, malignancy should be considered in the diagnosis of a pediatric and adolescent breast mass until formally ruled out. PMID- 30288008 TI - Prospective Evaluation of Surgical Outcome After Transoral CO2 Laser Resection of Potentially Malignant and Early Oral Malignancy. AB - A prospective observational study was done at the Regional Cancer Centre, Thiruvananthapuram, a tertiary referral center for cancer care in India with an aim to assess the surgical outcomes of CO2 laser resection of oral lesions in terms of operative time, blood loss, hospital stay, postoperative pain, time to re-epithelization, pathological margins achieved and the postoperative scar. The excision was performed in 30 patients with a diagnosis of either potentially malignant lesions (leucoplakia, erythroplakia) or early cancers, i.e., carcinoma in situ or T1/T2 squamous cell carcinoma of the anterior oral cavity (tongue, buccal mucosa), adhering to standard oncological principles, and the resultant defect was left for secondary healing. PMID- 30288010 TI - Encapsulated Follicular Variant of Papillary Thyroid Carcinoma Arising in a Follicular Adenoma: a Diagnostic Dilemma. AB - Papillary thyroid carcinoma (PTC) arising within follicular adenoma is a rare histological subset of papillary carcinoma. A 24-year-old female (euthyroid and asymptomatic) presented with a solitary mass in the right lobe of thyroid for 2 years. Fine-needle aspiration cytology (FNAC) suggested features of hyperplasia of thyroid. Hemithyroidectomy was performed. Histopathological examination revealed two distinct areas and was reported as encapsulated variant of papillary carcinoma along with follicular adenoma. Papillary carcinoma was confirmed by positive immunohistochemistry for HBME-1. CT head and neck region ruled out metastasis and the patient was kept on follow-up. There have been reports of medullary and papillary carcinomas occurring together; however, there is a paucity of literature on co-existing follicular neoplasm and papillary carcinoma. We hereby report a rare case of follicular variant of papillary carcinoma arising within follicular adenoma of the thyroid. PMID- 30288009 TI - Acute Trauma Precipitating the Onset of Chest Wall Myxofibrosarcoma. AB - A previously healthy, 47-year-old male presented to his primary care physician with the complaint of a nontender, palpable breast mass discovered coincidentally 1 month after being scratched in the same location by his pet cat. Family history revealed his father was diagnosed with a soft tissue sarcoma of the thigh, 6 months following a traumatic injury in the same location. Cat scratch disease was considered; however, Bartonella Henselae antibody testing was negative. Imaging studies revealed a subpectoral mass without rib involvement. Subsequent core biopsy revealed malignant fibrous histiocytoma, myxoid type, also known as myxofibrosarcoma. The patient underwent complete surgical resection with no complications. Medical advice recommended adjuvant radiation therapy due to the high risk of recurrence; however, the patient refused this option. Twenty-five months later, the patient remains in remission and in overall good health. This case describes the development of a chest wall tumor, diagnosed as myxofibrosarcoma, following acute trauma to the area. The association between acute traumatic injury and the development of a soft tissue sarcoma, as described in this case, continues to be widely reported, suggesting the possibility for an underlying causal mechanism. Future studies are required to unravel the pathogenesis in order to advance the management of this disease. PMID- 30288011 TI - Current Status of Lymphadenectomy During Radical Nephroureterectomy for Upper Tract Urothelial Cancer-Yes, No or Maybe? AB - While pelvic lymphadenectomy during radical cystectomy for bladder cancer is a well-established standard of care, the same does not hold true for upper tract urothelial carcinoma (UTUC). Indeed, a template-based lymphadenectomy is rarely, if ever, performed in conjunction with radical nephroureterectomy at most centres across the globe. While multiple studies have explored the staging and therapeutic role of lymphadenectomy in cases of UTUC, there remain large gaps in our understanding of the indications, extent and safety of this procedure as an adjunct to nephroureterectomy. This article elucidates the current knowledge on outcomes, benefits and complications of template-based lymphadenectomy during radical nephroureterectomy for UTUC. We also explore the current evidence-based guidelines on this controversial topic. PMID- 30288012 TI - Resection of Isolated Port Site Metastasis in Gall Bladder Cancers-Careful Selection and Perioperative Systemic Therapy May Improve Outcomes. AB - Excision of port site (PSE) for patients having undergone laparoscopic cholecystectomy (LC) is not a standard recommendation. We retrospectively evaluated a cohort of patients with isolated PSM without any prior cancer directed therapy who were assessed for resection between March 2012 and July 2016 at Tata Memorial Hospital, Mumbai. Eleven of a total 13 patients underwent wide excision for PSM in the given time period. Upfront resection was undertaken in six patients while seven patients received neoadjuvant chemotherapy (NACT) and two received neoadjuvant chemo radiotherapy (NACTRT) prior to attempted resection. With the median follow-up of 22 months, post PSM disease-free survival (DFS) was 20 months (95% CI 15-24 months) and overall survival (OS) was 37 months (95% CI 22-51 months). Careful selection along with an aggressive management strategy may be a step forward in the treatment of patients with isolated PSM.

AB - Retroperitoneal teratoma involving adrenal gland is a rare entity in adults comprising only 4% of all primary teratomas. These tumors are mainly seen in infants and children. Diagnosis is made by X-ray and CT abdomen showing the presence of large tumor with cystic and calcified walls. Here, we present an interesting image of a 16-year-old girl who presented with large (12 * 10 cm) calcified cyst occupying left side of abdomen which was treated successfully by surgical excision. PMID- 30288015 TI - Agronomic biofortification of cereal crop plants with Fe, Zn, and Se, by the utilization of coal fly ash as plant growth media. AB - The implementation of agronomic biofortification of cereal crops with Fe, Zn, and Se appears to be a rapid and simple solution to the deficiency of these elements in soils and plants. These deficiencies are a reason for serious public health concerns. Low levels of Fe, Zn, and Se are important soil constraints to crop production, especially in the developing world. In our study we planted six cereal crops on soil control and different coal combustion residues, naturally rich in these micronutrients. Plants were harvested and chemically analyzed for Fe, Zn, and Se concentration using ICP. Six plant species have been tested including barley (Hordeum vulgare), Jerry oats (Avena sativa), rye (Secale cereale), wheat (Triticum aestivum), perennial ryegrass (Lolium multiflorum), and ReGreen (wheat x wheatgrass hybrid (Triticum aestivum x Thinopyrum intermedium). All tested plants were able to establish growth on coal ash based growth media, and accumulated significant amounts of Fe, Zn, and Se. It supported our hypothesis, that phytoremediation of coal ash piles may serve also as agronomic biofortification of plants, especially cereal crops cultivated on coal fly ash (FA). PMID- 30288016 TI - Mechanism and Catalysis of Oxidative Degradation of Fiber-Reinforced Epoxy Composites. AB - Carbon fiber-reinforced polymer (CFRP) materials are widely used in aerospace and recreational equipment, but there is no efficient procedure for their end-of-life recycling. Ongoing work in the chemistry and engineering communities emphasizes recovering carbon fibers from such waste streams by dissolving or destroying the polymer binding. By contrast, our goal is to depolymerize amine-cured epoxy CFRP composites catalytically, thus enabling not only isolation of high-value carbon fibers, but simultaneously opening an approach to recovery of small molecule monomers that can be used to regenerate precursors to new composite resin. To do so will require understanding of the molecular mechanism(s) of such degradation sequences. Prior work has shown the utility of hydrogen peroxide as a reagent to affect epoxy matrix decomposition [1]. Herein we describe the chemical transformations involved in that sequence: the reaction proceeds by oxygen atom transfer to the polymer's linking aniline group, forming an N-oxide intermediate. The polymer is then cleaved by an elimination and hydrolysis sequence. We find that elimination is the slower step. Scandium trichloride is an efficient catalyst for this step, reducing reaction time in homogeneous model systems and neat cured matrix blocks. The conditions can be applied to composed composite materials, from which pristine carbon fibers can be recovered. PMID- 30288017 TI - A 15-channel 30-V Neural Stimulator for Spinal Cord Repair. AB - This paper presents a 15-channel, 30-V, implantable current stimulator for restoring locomotion control after spinal cord injuries. The stimulator features performance specifications comparable to those of large desktop instrumentation: high linearity, high precision of the delivered currents, small channel-to channel mismatches and a fast settling time of 0.3 MUs. An ADC-based active charge balancing scheme using a digital PI (proportional-integral) controller was implemented in firmware. PMID- 30288018 TI - Murrangatin suppresses angiogenesis induced by tumor cell-derived media and inhibits AKT activation in zebrafish and endothelial cells. AB - Introduction: Lung cancer is a major cancer type and a leading cause of cancer related death. Angiogenesis plays a crucial role in lung cancer pathogenesis and its inhibition is beneficial to patients. Materials and methods: Murrangatin, a natural product, can inhibit the proliferation of lung cancer cells, so herein we investigated its anti-angiogenic effects in transgenic zebrafish TG (fli1: EGFP) and in lung cancer cell-induced angiogenesis in human umbilical vein endothelial cells. Results: We found that murrangatin strongly inhibited the growth of subintestinal vessels in zebrafish embryos and tumor conditioned media-induced angiogenic phenotypes including cell proliferation, cell invasion, cell migration, and tube formation. Additionally, murrangatin greatly attenuated conditioned medium-induced AKT phosphorylation, but not extracellular signal regulated kinase 1/2 phosphorylation. Discussion and conclusion: These findings indicate that murrangatin can inhibit tumor-induced angiogensis, at least in part through the regulation of AKT signaling pathways. Murrangatin may, therefore, be a potential candidate for the development of new anti-lung-cancer drugs. PMID- 30288021 TI - Intravenous tranexamic acid use in revision total joint arthroplasty: a meta analysis. AB - Purpose: Massive perioperative blood loss in complex revision total joint arthroplasty (TJA) often requires blood transfusions. Tranexamic acid (TXA) has been used in elective primary TJA to minimize blood loss and transfusions. The purpose of this meta-analysis was to evaluate the safety and efficacy of intravenous TXA in revision TJA. Methods: A literature search of PubMed, Scopus, and the Cochrane Controlled Trials Register was performed to identify studies published between January 2000 and May 2017. All randomized controlled trials (RCTs) and retrospective cohort observational studies evaluating the efficacy of intravenous TXA during revision total knee arthroplasty (TKA) and total hip arthroplasty (THA) were included. The mean differences (MDs) of blood loss, hemoglobin (Hb) change, and red blood cell (RBC) units transfused were compiled, and ORs of transfusion and venous thromboembolism (VTE) events in TXA and control groups were calculated. Results: Seven studies involving 930 patients were included (501 TXA vs 429 control). Intravenous TXA use had a significantly less blood transfusion (OR=0.20, 95% CI=0.11-0.34, P<0.001), lower Hb drop (MD=-0.88, 95% CI=-1.31 to -0.44, P<0.001), and less number of RBC units transfused (MD= 0.44, 95% CI=-0.65 to -0.24, P<0.001) compared to control in the postoperative period. No significant difference was seen in blood loss (MD=-245, 95% CI=-556 to 66, P=0.12) and VTE events (OR=0.57, 95% CI=0.13-2.42, P=0.45) between groups. Conclusion: Our meta-analysis suggests that intravenous administration of TXA can significantly reduce blood transfusion requirements following revision TJA, without increasing the risk of VTE. However, due to the variation in included studies, larger RCTs are required to draw firm conclusions. PMID- 30288020 TI - Profile of asfotase alfa in the treatment of hypophosphatasia: design, development, and place in therapy. AB - Hypophosphatasia (HPP) is a multi-systemic metabolic disorder caused by loss-of function mutations in the ALPL gene that encodes the mineralization-associated enzyme, tissue-nonspecific alkaline phosphatase (TNSALP). HPP is characterized by defective bone and dental mineralization, leading to skeletal abnormalities with complications resulting in significant morbidity and mortality. Management of HPP has been limited to supportive care until the introduction of a recently approved enzyme replacement therapy employing bone-targeted recombinant human TNSALP, asfotase alfa (AA). This new therapy has been transformative as it improves survival in severely affected infants, and overall quality of life in children and adults with HPP. This review provides an overview of HPP, focusing on important steps in the development of AA enzyme replacement therapy, including the drug design, preclinical studies in the HPP mouse model, and outcomes from clinical trials and case report publications to date, with special attention given to response to therapy of skeletal manifestations, biochemical features, and other clinical manifestations. The limitations, adverse effects, and outcomes of AA are outlined and the place in therapy for individuals with HPP is discussed. PMID- 30288022 TI - Colorectal cancer combination therapy using drug and gene co-delivered, targeted poly(ethylene glycol)-epsilon-poly(caprolactone) nanocarriers. AB - Purpose: Combination therapy is a promising strategy to treat cancer due to the synergistic effects. The drug and gene co-delivered systems attract more attention in the field of combination therapy. Materials and methods: In the present research, poly(ethylene glycol)-epsilon-poly(caprolactone) block copolymer was used for the co-loading of 5-fluorouracil (5-FU) and gene. The physicochemical characteristics, in vitro and in vivo anticancer, and gene transfection efficiency were tested on colon cancer cells and tumor-bearing mice. Results: 5-FU and gene co-loaded nanocarriers had a size of 145 nm. In vivo gene delivery results showed about 60% of gene-positive cells. Tumor volume of nanocarrier groups at day 21 was around 320 mm3, which is significantly smaller compared with free 5-FU group (852 mm3) and control group (1,059 mm3). The maximum 5-FU plasma concentration in nanocarrier groups (49 ug/mL) was significantly greater than free 5-FU (13 ug/mL). At 24 hours, drug level of nanocarrier groups was about 2.8 ug/mL compared with 0.02 ug/mL of free 5-FU. Conclusion: The resulting nanocarriers co-loaded with the anticancer drugs and genes could be considered as a promising nanomedicine for colorectal cancer therapy. PMID- 30288024 TI - Synergistic combination therapy of lung cancer using paclitaxel- and triptolide coloaded lipid-polymer hybrid nanoparticles. AB - Purpose: Non-small cell lung cancer (NSCLC) accounts for the majority of lung cancer. Lipid-polymer hybrid nanoparticles (LPNs) combine the advantages of both polymeric nanoparticles and liposomes into a single delivery platform. In this study, we engineered LPNs as the co-delivery system of paclitaxel (PTX) and triptolide (TL) to achieve synergistic therapeutic effect and reduced drug resistance. Materials and methods: In this study, PTX- and TL-coloaded LPNs (P/T LPNs) were fabricated by nanoprecipitation method using lipid and polymeric materials. The P/T-LPNs combination effects on human lung cancer cells were studied. Therapeutic potentials of P/T-LPNs were further determined using lung cancer cells-bearing mice model. Results: The average particle sizes of LPNs were around 160 nm, with narrow size distribution below 0.2. The zeta potential value of LPNs was about -30 mV. The encapsulating efficiency (EE) of PTX and TL loaded in LPNs was over 85%. The cytotoxicity of dual drug loaded LPNs was higher than single drug loaded LPNs. The combination therapy showed synergistic when PTX:TL weight ratio was 5:3, indicating the synergy effects of the LPNs. In vivo tumor growth curve of the experimental group was more gentle opposed to the control group, and tumor volumes of P/T-LPNs and control group were 392 and 1,737 mm3, respectively. The inhibition rate on day 20 was 77.4% in the P/T-LPNs group, which is higher than the free drugs solution. Conclusion: The in vivo and in vitro results proved the synergetic effect of the two drugs coloaded in LPNs on the lung cancer xenografts, with the least systemic toxic side effect. PMID- 30288019 TI - Current development of biodegradable polymeric materials for biomedical applications. AB - In the last half-century, the development of biodegradable polymeric materials for biomedical applications has advanced significantly. Biodegradable polymeric materials are favored in the development of therapeutic devices, including temporary implants and three-dimensional scaffolds for tissue engineering. Further advancements have occurred in the utilization of biodegradable polymeric materials for pharmacological applications such as delivery vehicles for controlled/sustained drug release. These applications require particular physicochemical, biological, and degradation properties of the materials to deliver effective therapy. As a result, a wide range of natural or synthetic polymers able to undergo hydrolytic or enzymatic degradation is being studied for biomedical applications. This review outlines the current development of biodegradable natural and synthetic polymeric materials for various biomedical applications, including tissue engineering, temporary implants, wound healing, and drug delivery. PMID- 30288025 TI - Lycium barbarum polysaccharide prevents cisplatin-induced MLTC-1 cell apoptosis and autophagy via regulating endoplasmic reticulum stress pathway. AB - Background: Lycium barbarum polysaccharide (LBP) has been reported to contribute to the recovery of male hypogonadism and infertility. Aim: The aim of current study was to investigate the underlying mechanisms of LBP on male infertility recovery. Methods: Recently, it is reported that cell apoptosis mediated by endoplasmic reticulum stress (ERS) was distinguished from that mediated by death reporters and mitochondria pathway, which could induce cell apoptosis independently. The possible signaling mechanisms were investigated using diversified molecular biology techniques, such as flow cytometry, western blotting, and immunofluorescence. Results: In this study, we found that LBP protected Leydig MLTC-1 cells against cisplatin (DDP) by regulating ERS-mediated signal pathway, which was evidenced by downregulation of phosphorylation PERK, phosphorylation of eukaryotic translation-initiation factor 2alpha and activating transcription factor 4. Meanwhile, LBP decreased DDP-induced MLTC-1 cell apoptosis via reducing ERS apoptosis-relative proteins caspase 3, caspase 7, and caspase 12. In addition, the result of monodansylcadaverine staining indicated that LBP significantly inhibited DDP-induced autophagosome formation in MLTC-1 cells. Moreover, immunofluorescences and Western blot assays demonstrated that LBP reversed DDP-induced LC3II and Atg5 upregulation in MLTC-1 cells. Finally, the data of enzyme-linked immunosorbent assay showed that LBP markedly recovered MLTC-1 cells testosterone level even in the presence of DDP. Conclusion: Thus, we suggest that LBP protected MLTC-1 cells against DDP via regulation of ERS mediated apoptosis and autophagy. PMID- 30288023 TI - Design and development of Nrf2 modulators for cancer chemoprevention and therapy: a review. AB - A major cell defense mechanism against oxidative and xenobiotic stress is mediated by the Nrf2/Keap1 signaling pathway. The Nrf2/Keap1 pathway regulates gene expression of many cytoprotective and detoxifying enzymes, thus playing a pivotal role in maintaining redox cellular homeostasis. Many diseases including cancer have been closely related to impaired Nrf2 activity. Targeting Nrf2 and modulating its activity represents a novel modern strategy for cancer chemoprevention and therapy. In this review, different design strategies used for the development of Nrf2 modulators are described in detail. Moreover, the main focus is on important and recently developed Nrf2 activators and inhibitors, their in vitro and in vivo studies, and their potential use as chemopreventive agents and/or cancer therapeutics. PMID- 30288026 TI - Cancer patients treated with intravenous chemotherapy for the first time. What are their needs? What do they lack? A qualitative-quantitative mixed approach. AB - Introduction: The announcement of cancer coupled with initiation of its treatment impacts patients' psychological and physical states as well as their lifestyles. The objective of this study was to identify and confirm the needs of patients starting off on anticancer chemotherapy treatment. Methods: This study was based on a qualitative-quantitative mixed method. In 2009, a qualitative study was conducted at the Lucien Neuwirth Cancer Institut for cancer patients undergoing intravenous chemotherapy for the first time. Exploratory and semi-directed interviews were carried out by a sociologist. In 2014, a questionnaire was hetero administered to 100 patients starting off on chemotherapy. Results: Forty patients were interviewed in 2009. Ninety-seven patients answered the questionnaire in 2014. Food was a theme that was identified by a majority of patients in 2009 (13/40) and confirmed in 2014: 63% needed help in identifying favorable food and 67% in identifying those that had to be avoided. The other needs identified were those linked to better understanding of the treatment, of how it may affect the couple, its side effects, hygiene and beauty, and knowledge about other treatments. These needs were confirmed in 2014. New needs were elicited in 2014: activities and leisure (33%), psychological needs (32.6%), and family relations (29.9%). Conclusion: This study enabled us to identify, confirm, and enrich our knowledge of the needs of cancer patients starting off on intravenous chemotherapy. These results led to the modification of an existing patient education program for these patients, in order to fulfill their needs in an updated and tailored manner. PMID- 30288027 TI - Consumer-related factors influencing antidepressant adherence in unipolar depression: a qualitative study. AB - Purpose: To explore factors which facilitate and negatively impact adherence, at initiation, implementation and discontinuation phases of adherence to antidepressant medicines. Patients and methods: Semi-structured, face-to-face interviews were conducted with patients suffering from unipolar depression. The digitally audio-recorded and transcribed verbatim were used. Transcripts were thematically content analyzed and data managed using N-Vivo software. Results: Twenty-three interviews were conducted. The predominant factors facilitating initiation of therapy included self-motivation and severity of depression. Factors aiding persistence with therapy included belief in, and effectiveness of, antidepressants. Stigma and fear of adverse events inhibited initiation of therapy, whilst adverse events and ineffectiveness of antidepressants contributed to discontinuation. Patients with strong perceptions of the necessity and few concerns about antidepressants were more likely to adhere to treatment at all phases of adherence. Conclusion: Different factors influence medication adherence at the different phases of adherence. These factors were based on individual perceptions about depression and its treatment, and actual experiences of antidepressant treatment. This information should be considered by health care professionals in delivering targeted and tailored interventions to foster adherence. Strategies to address medication non-adherence in unipolar depression patients should consider the phase of adherence and individual perceptions about depression and its treatment, along with previous experiences with treatment for depression. PMID- 30288028 TI - Patient-doctor relationship and adherence to capecitabine in outpatients of a German comprehensive cancer center. AB - Purpose: The prescribing of oral chemotherapy agents has introduced the new challenge of ensuring patients' adherence to therapy. Aspects of a close patient doctor relationship are reported to be correlated with adherence to oral anticancer drugs, but data on capecitabine are scarce. Patients and methods: Sixty-four outpatients with a diagnosis of cancer and prescribed capecitabine were recruited from a German Comprehensive Cancer Center. We used the Patient Doctor Relationship Questionnaire (PDRQ-9), the Medical Adherence Rating Scale (MARS), the Beliefs about Medicines Questionnaire (BMQ), and the Satisfaction with Information about Medicines Scale (SIMS) to assess patients' perceptions and behavior. Medical data were extracted from the charts. Results: Non-adherence was reported by 20% of the 64 participants. The perceived quality of the patient doctor relationship was high in general, but it did not emerge as a predictor of adherence in our survey (odds ratio [OR]=0.915, P=0.162, 95% CI=0.808-1.036). However, beliefs about medicine (OR=1.268, P<0.002; 95% CI=1.090-1.475) as well as satisfaction with information about medicine (OR=1.252, P<0.040, 95% CI=1.010 1.551) were predictors of adherence and the quality of the patient-doctor relationship was correlated with both variables (r=0.373, P=0.002 for SIMS sum score; r=0.263, P=0.036 for BMQ necessity/concern difference). Overall, adherence to capecitabine was high with a conviction that the therapy is necessary. However, concerns were expressed regarding the long-term effect of capecitabine use. Patients have unmet information needs regarding interactions of capecitabine with other medicines and the impairment of their intimate life. Conclusions: In order to ensure adherence to capecitabine, our results seem to encourage the default use of modern and perhaps more impersonal means of information brokerage (eg, email, internet). However, the contents of some of patients' informational needs as well as the associations of patients' beliefs and satisfaction about the information received suggest a benefit from a trustful patient-doctor relationship. PMID- 30288029 TI - Caregivers' misperception of the severity of hip fractures. AB - Purpose: The aim of our study was to evaluate how the caregiver of a hip fracture patient perceives the patient's health status and autonomy in the period immediately preceding the acute event and whether these judgments are actually in line with the prognosis predicted by the medical team caring for the patient in the rehabilitation structure. Patients and methods: We enrolled 147 patients of both sexes, aged >=65 years, who were referred to our center following surgical treatment of hip fractures of various nature. At the beginning of the rehabilitation program, each patient's caregiver was asked to complete the Blaylock Risk Assessment Screening Score (BRASS) questionnaire. The same questionnaire was compiled contemporaneously by the doctor taking care of the patient. Results: Analysis of the data shows that the caregivers tend to assign lower scores than the doctor, with a mean difference in agreement with the Bland Altman plot of -2.43, 95% CI=-2.93 to -1.93, t-test P<0.001. Furthermore, differences in objectivity emerge in the evaluation of the clinical problems of the patient in a borderline clinical condition. Conclusion: This study revealed that caregivers systematically misperceive the clinical situation of hip fracture patients prior to the acute event. Altered perception of such an important factor can lead to a general lack of satisfaction with the outcome achieved by the patient at the end of the rehabilitation process. We therefore believe that an adequate, effective communication between the people making up the health care team and the patient's social and family network is the foundation of the rehabilitation process. It is precisely on this foundation that the individual's care and assistance need to be assembled. PMID- 30288030 TI - Patients' satisfaction and subjective happiness after refractive surgery for myopia. AB - Purpose: The purpose of this study was to assess patients' satisfaction and change in subjective happiness after laser-assisted in situ keratomileusis (LASIK). Patients and methods: This was a retrospective cross-sectional study of 307 patients (mean age, 34.3 years; range, 20-63 years) who underwent bilateral LASIK surgery and ocular examinations, including subjective refraction and visual acuity axial length measurements at Minamiaoyama Eye Clinic. Patients also completed questionnaires on their satisfaction with the surgery, and on the subjective happiness scale (SHS) within 1 month before and 1 month after surgery. A multiple regression analysis was performed to determine the independent predictors of the SHS score. Results: In total, 91.2% of the patients were satisfied with surgery (very satisfied: n=155; satisfied: n=125). The SHS score increased postoperatively from 5.2+/-0.9 to 5.3+/-0.9 (P<0.001). The multiple regression analysis revealed that the preoperative SHS score (beta=0.77; P<0.001) and satisfaction with surgery (beta=-0.11; P=0.05) were predictors of postoperative SHS score. Conclusion: LASIK may contribute to increased patient happiness. PMID- 30288031 TI - Patient activation for self-management is associated with health status in patients with atrial fibrillation. AB - Background: Higher levels of patient activation for self-managing health are associated with positive clinical and health care utilization outcomes. Identifying a patient's activation level can guide clinicians to tailor interventions to improve their health. Effective self-management of atrial fibrillation (AF) requires patient activation to participate in treatment decisions, prevent complications, and manage risk factors. Yet, little is known about activation in patients with AF. The purpose of this descriptive study was to identify patient activation levels and factors associated with activation in patients with AF. Methods: Patients (N=123), 66% male, with a mean (SD) age of 59.9 (11.3) years seeking treatment for AF at an arrhythmia clinic completed the Patient Activation Measure (PAM), Atrial Fibrillation Severity Scale, Knowledge about Atrial Fibrillation test, Hospital Anxiety Depression Scale, Godin Leisure Time Exercise Questionnaire, and Patient Assessment of Chronic Illness Care. Sociodemographic and clinical data were obtained from medical records. PAM scores were categorized into Levels 1-4. Associations among patient-reported outcomes, sociodemographic, and clinical variables were analyzed using Fisher's exact tests and Kruskal-Wallis procedures. Results: The PAM scores of nearly half (45.5%) of the patients were at Level 3, while the scores of 38% were at Level 4. Male sex (P=0.02), higher education (P=0.004), being employed (P=0.005), lower body mass index (P=0.03), tobacco abstinence (P=0.02), less AF symptom burden (P=0.006), less depression (P<=0.0001) and anxiety (P=0.006), greater knowledge of AF (P=0.01), and higher levels of physical activity (P=0.02) were associated with higher activation levels. Conclusion: Higher levels of patient activation in those with AF were associated with a more positive health status and educational attainment. Additional research to describe activation in patients with AF is warranted to identify patients at risk for low activation and to tailor interventions to activation level. PMID- 30288032 TI - Feasibility and willingness to pay for dengue vaccine in the threat of dengue fever outbreaks in Vietnam. AB - Background: The escalation of dengue fever (DF) cases in recent years and the occurrence of a large-scale DF outbreak in 2017 underline the importance of dengue vaccines in Vietnam. Given the potential benefits of the dengue vaccines and the need for copayment by the private sector, this study aims to evaluate the willingness to pay (WTP) for the dengue vaccines in patients with DF in Northern Vietnam. Methods: A cross-sectional study was conducted on 330 in-and-out patients with DF admitted to the Bach Mai Hospital. We used the contingent valuation method to evaluate the WTP for dengue vaccines. Socioeconomic and clinical characteristics were also investigated. Multivariate interval and logistic regression models were used to estimate the average amount of WTP and identify the factors associated with the WTP. Results: Around 77.3% patients were willing to pay an average amount of US$ 67.4 (95% CI=57.4-77.4) for the vaccine. People of higher ages, those having health insurance, those traveling in the past 15 days or suffering from anxiety/depression were less likely to be willing to pay for the dengue vaccine. However, people having a longer duration of DF or having problems with mobility were positively associated with WTP for the dengue vaccine. Patients educated to more than high school levels (Coeff.=31.31; 95% CI=3.26-59.35), those in the richest quintile (Coeff.=62.76; 95% CI=25.40; 100.13), or those having a longer duration of the disease (Coeff.=6.18; 95% CI=0.72-11.63) were willing to pay a higher amount. Conclusion: This study highlights a relatively high rate and amount of WTP for the dengue vaccine among patients with DF. Psychological counseling services as well as educational campaigns should be undertaken to improve the WTP for the vaccine. Moreover, government subsidies should be given to increase the coverage of the vaccine in the future, especially for the poor. PMID- 30288033 TI - A multivariate investigation into the relationship between pharmaceutical characteristics and patient preferences of bioequivalent ibuprofen tablets. AB - Background: In Spain the price of all ibuprofen 600 mg tablet generic products is the same due to reimbursement existing rules so for the patient there is not any economic incentive to choose a particular one. Bearing in mind that the quality of generic products should be similar, it could be questioned if differences in patient preferences evaluated as sales could be related to differences on their pharmaceutical properties. The aims of this work were to study the variability on the pharmaceutical characteristics of marketed bioequivalent tablet formulations and its impact on patient preferences. Methods: Thirty-six batches corresponding to fourteen different generic products were chosen among the best-selling products of the Spanish market in the years 2011 and 2015 and were compared to the reference product. The effect on patient preferences of six variables was studied through a multivariate analysis. The first two variables were marketing characteristics: 1) years in the market and 2) the number of other generic products marketed by the same manufacturer, which could be related to the size and service provided by the manufacturer. The other four variables studied were pharmaceutical tablet properties: 3) mean weight, 4) hardness, 5) disintegration, and 6) dissolution. A multiple linear regression analysis was performed to identify the effect on sales of the six variables studied. Results: The disintegration time was the most significant (P=0.018) factor affecting the sales of Ibuprofen tablets which may be related to the onset of action. Conclusion: The faster the tablet disintegration, the higher its sales. Two possible explanations are suggested: 1) the most specialized ibuprofen tablet manufacturer considers fast disintegration as a key parameter and/or 2) habitual consumers of ibuprofen can detect small differences on the onset of action among different marketed formulations. In this work, all marketed ibuprofen tablets comply with the pharmacopoeia specifications. PMID- 30288034 TI - Time preference, outcome expectancy, and self-management in patients with type 2 diabetes. AB - Background: Patient self-management is crucial to prevent complications and mortality in type 2 diabetes. From an economic perspective, time preference predicts short-sighted decision making and thus might help to explain non adherence to self-anagement recommendations. However, recent studies on this association have shown mixed results. Purpose: In this study, we tested whether the combination of time preference and outcome expectancy can improve the predictions of self-management behavior. Patients and methods: Data from 665 patients with type 2 diabetes were obtained from the cross-sectional KORA (Cooperative Health Research in the Region of Augsburg) GEFU 4 study. Time preference and outcome expectancy were measured by one question each, which were answered on a 4-point Likert scale. Their association with six self-managing behaviors was tested in logistic and linear regression analyses. Likewise, we examined the association between self-management and the interaction of outcome expectancy and time preference. Results: A high time preference was associated with a significantly lower sum of self-management behaviors (beta=-0.29, 95% CI [ 0.54, -0.04]). Higher outcome expectancy was associated with a higher self management score (beta=0.21, 95% CI [-0.03, 0.45]). The interaction model showed that low time preference was only associated with better self-management when combined with a high outcome expectancy (beta=0.05, 95% CI [-0.28, 0.39] vs beta=0.27, 95% CI [-0.09, 0.63]). Conclusion: Time preference and outcome expectancy are interrelated predictors of patient self-management and could be used to identify and to intervene on patients with a potentially poor self management. PMID- 30288035 TI - Isotemporal substitution of sedentary time with physical activity and its associations with frailty status. AB - Objectives: Recently, isotemporal substitution has been developed to substitute activity time for an equivalent amount of another activity. This study employed this method to demonstrate the effects of replacing sedentary behavior (SB) time with an equivalent amount of light-intensity physical activity (LPA) and moderate to-vigorous intensity physical activity (MVPA) on the risk for different severities of frailty. Methods: A total of 886 older adults (average age 73.6 years, female 70%) participated in this cross-sectional study. Frailty status was assessed according to the cardiovascular health study criteria. Main outcome measures: Wrist-worn accelerometers were used to measure SB, LPA, and MVPA. Isotemporal substitution models were applied to show the estimated effects of substituting 30 min of SB with an equal amount of time spent in LPA or MVPA on the risk for pre-frailty and frailty. Results: The physical activity level and SB were not associated with the incidence of pre-frailty. However, a 16% (OR: 0.84; 95% CI: 0.78-0.90) and 42% (OR: 0.58; 95% CI: 0.37-0.92) decrease in frailty risk was noted when SB was substituted with LPA and MVPA, respectively, in the crude model. In the adjusted model, the significant effect was sustained for LPA (OR: 0.86; 95% CI: 0.80-0.92) but not for MVPA (OR: 0.74; 95% CI: 0.47-1.17). Conclusions: This study indicates that replacing 30 min of SB with an equivalent amount of LPA decreases the risk for frailty in older adults. Moreover, increasing LPA seems more feasible than increasing MVPA in older adults, with substantial benefit. PMID- 30288036 TI - The influence of carbon dioxide field flooding in mitral valve operations with cardiopulmonary bypass on S100beta level in blood plasma in the aging brain. AB - Introduction: The risk of air microembolism during cardiopulmonary bypass (CPB) is high and influences the postoperative outcome, especially in elderly patients. The use of carbon dioxide (CO2) atmosphere during cardiac surgery may reduce the risk of cerebral air microembolism. The aim of our study was to assess the influence of CO2 field flooding on microembolism-induced brain damage assessed by the level of S100beta protein, regarded as a marker of brain damage. Materials and methods: A group of 100 patients undergoing planned mitral valve operation through median sternotomy using standard CPB was recruited for the study. Echocardiography was performed prior to and after the CPB. CO2 insufflation at 6 L/minute was conducted in the study group. Blood samples for S100beta protein analysis were collected after induction of anesthesia, 2 hours after aorta de clamping, and 24 hours after operation. Results: The S100beta level in blood plasma did not differ significantly between the study and the control group (0.13+/-0.08 ug/L, 1.12+/-0.59 ug/L, and 0.26+/-0.23 ug/L and 0.18+/-0.19 ug/L, 1.31+/-0.62 ug/L, and 0.23+/-0.12 ug/L, P=0.7, 0.14, and 0.78). The mean increase of the S100beta concentration was 13% lower in the group with CO2 protection than in the control group (0.988 ug/L vs 1.125 ug/L), although statistically insignificant. Tricuspid valve annuloplasties (TVAs) had significant impact on the increase in S100beta concentration in the treatment group after 24 hours (TVA [-] 0.21+/-0.09 vs TVA [+] 0.42+/-0.42, P=0.05). In patients <60 years, there were significant differences in the S100beta level 2 and 24 hours after the procedure (1.59+/-0.682 ug/L vs 1.223+/-0.571 ug/L, P=0.048, and 0.363+/-0.318 ug/L vs 0.229+/-0.105 ug/L, P=0.036) as compared with younger patients. Conclusion: The increase in S100beta concentration was lower in the group with CO2 protection than in the control group. Age and an addition of TVA significantly influenced the level of S100beta concentration in the tests performed 2 hours after aortic clamp release. PMID- 30288037 TI - A comparative analysis of errors in inhaler technique among COPD versus asthma patients. AB - Purpose: This study was designed to evaluate errors in inhaler technique in COPD vs asthma patients and to investigate the association of poor inhaler technique with patient demographics and clinical variables. Patients and methods: A total of 509 adult patients with COPD (n=328) or asthma (n=181) who were currently using an inhaler device were included in this study. Data on patient demographics, duration of disease, type and duration of inhaler therapy, and assessment of inhaler technique were recorded. Results: Metered dose inhaler (MDI) was the most common type of inhaler used by a similarly high percentage of patients in both COPD (83.2%) and asthma (77.3%) groups. Failure to exhale before inhaling through device (75.8% and 68.5% for MDIs; 73.2% and 71.8% for Aerolizer(r)/Handihaler(r); 53.1% and 66.7% for Turbuhaler(r)) was the most common error in inhaler technique, in both COPD and asthma groups. Device specific errors in inhaler techniques were more common in asthma patients as compared with COPD patients, particularly for MDIs (P-values ranged from 0.046 to 0.0005), as associated with female gender (failure to press the buttons on both sides of Aerolizer(r)/Handihaler(r), P=0.006), shorter duration of disease (failure to hold MDI or head in a vertical position, P<0.001, and to keep Turbuhaler(r) upright, P=0.005), and shorter duration of inhaler usage (failure to hold head in a vertical position during MDI usage, P=0.006, and to keep Turbuhaler(r) upright, P=0.012). Conclusion: In conclusion, our findings revealed that errors in inhaler technique in terms of inhalation maneuvers and device handling were similarly common in COPD and asthma patients. Errors in certain device handling maneuvers, particularly with MDIs, were more common among asthma patients than among COPD patients and associated with female gender and shorter durations of disease and inhaler therapy. PMID- 30288039 TI - Effects of PEG surface density and chain length on the pharmacokinetics and biodistribution of methotrexate-loaded chitosan nanoparticles. AB - Background: One of the most important aspects of drug delivery is extended nanoparticle (NP) residence time in vivo. Herein, we report a series of methotrexate (MTX)-loaded chito-san (CS) NPs coated with differently sized methoxy polyethylene glycol (mPEG) at different mPEG surface densities. Materials and methods: MTX was incorporated into NPs (112.8-171.2 nm in diameter) prepared from the resulting mPEG-g-CS. The NPs had a zeta potential of +7.4-35.0 mV and MTX loading efficiency of 17.1%-18.4%. MTX/mPEG-g-CS NPs showed an initial burst release of MTX followed by a sustained-release profile in PBS at pH 7.4. Results: The in vitro cellular uptake study showed that MTX accumulation in J774A.1 macrophage cells decreased with increasing the mPEG surface density or the mPEG molecular weight. The pharmacokinetic study on Sprague Dawley rats revealed an increase in AUC0-72 h (area under the plasma drug concentration-time curve over a period of 72 hours) with increasing the mPEG surface density or the mPEG molecular weight and a linear correlation between the mPEG surface density and AUC0-72 h. Conclusion: The biodistribution study on Institute of Cancer Research (ICR) mice revealed that MTX/mPEG-g-CS NPs significantly enhanced blood circulation time in the body and decreased accumulation in liver, spleen, and lung. These results suggest the potential of the mPEG-g-CS NPs as a promising candidate for drug delivery. PMID- 30288040 TI - Doxorubicin-loaded dextran-based nano-carriers for highly efficient inhibition of lymphoma cell growth and synchronous reduction of cardiac toxicity. AB - Purpose: Cardiac side effects of doxorubicin (Dox) have limited its clinical application. The aim of this study was to explore new Dox-loaded dextran-based nano-carriers (NCs) in efficiently targeting tumor growth with less cardiac toxicity. Methods: Inspired by recent reports that polymeric NCs could function as sustained, controlled and targeted drug delivery systems, we developed Dox loaded NCs which displayed a 2-fold release ratio of Dox in the mimic tumor site condition (pH 5.0 with 10 mM glutathione, GSH) as much as that in systemic circulation condition (pH 7.4). Results: Lymphoma cells treated with Dox-NCs had significantly higher intracellular Dox concentrations and more apoptotic induction, with lower P-gp expression, when compared with those treated with Dox alone. The identified mechanism of action, apoptosis, was triggered through survivin reduction and caspase-3 activation. Even in the Dox-resistant cells, Dox NCs could significantly inhibit cell growth and induce apoptosis. In murine lymphoma xenograft models, Dox-NCs also remarkably significantly retarded tumor growth, assessed by murine weight, and demonstrated less cytotoxicity. Noticeably, apoptotic myocardial cells were decreased in the Dox-NCs-treated group, when compared with the control group, which was consistent with low intracellular Dox concentration in the cardiac cell line H9C2. Conclusion: Dox NCs showed an anti-lymphoma effect with reduced cardiac toxicity in both in vivo and in vitro models and, therefore, could be a potential therapeutic agent in the treatment of lymphoma.

AB - Introduction: Graphene oxide nanoparticles have been widely used in industry and biomedical fields due to their unique physicochemical properties. However, comparative cytotoxicity of silver-doped reduced graphene oxide (rGO-Ag) nanoparticles on normal and cancerous liver cells has not been well studied yet. Materials and methods: This study aimed at determining the toxic potential of rGO Ag nanocomposite on human liver normal (CHANG) and cancer (HepG2) cells. The rGO Ag nanocomposite was characterized by using different advanced instruments, namely, dynamic light scattering, scanning electron microscope, and transmission electron microscope. Results: The rGO-Ag nanocomposite reduced cell viability and impaired cell membrane integrity of CHANG and HepG2 cells in a dose-dependent manner. Additionally, it induced reactive oxygen species generation and reduced mitochondrial membrane potential in both cells in a dose-dependent manner. Moreover, the activity of oxidative enzymes such as lipid peroxide, superoxide dismutase, and catalase were increased and glutathione was reduced in both cells exposed to rGO-Ag nanocomposite. Pretreatment with N-acetylcysteine inhibited cytotoxicity and reactive oxygen species generation in CHANG and HepG2 cells exposed to rGO-Ag nanocomposite (50 ug/mL). DNA damage was determined by Comet assay and maximum DNA damage occurred at rGO-Ag nanocomposite (25 ug/mL) for 24 h. It is also valuable to inform that HepG2 cells appear to be slightly more susceptible to rGO-Ag nanocomposite exposure than CHANG cells. Conclusion: This result provides a basic comparative toxic effect of rGO-Ag nanocomposite on hepatic normal and cancerous liver cells.

AB - Tissue engineering (TE) is an interdisciplinary field integrating engineering, material science and medical biology that aims to develop biological substitutes to repair, replace, retain, or enhance tissue and organ-level functions. Current TE methods face obstacles including a lack of appropriate biomaterials, ineffective cell growth and a lack of techniques for capturing appropriate physiological architectures as well as unstable and insufficient production of growth factors to stimulate cell communication and proper response. In addition, the inability to control cellular functions and their various properties (biological, mechanical, electrochemical and others) and issues of biomolecular detection and biosensors, all add to the current limitations in this field. Nanoparticles are at the forefront of nanotechnology and their distinctive size dependent properties have shown promise in overcoming many of the obstacles faced by TE today. Despite tremendous progress in the use of nanoparticles over the last 2 decades, the full potential of the applications of nanoparticles in solving TE problems has yet to be realized. This review presents an overview of the diverse applications of various types of nanoparticles in TE applications and challenges that need to be overcome for nanotechnology to reach its full potential. PMID- 30288043 TI - Subjective memory complaint as a useful tool for the early detection of Alzheimer's disease. AB - Purpose: Despite their high prevalence in Alzheimer's disease (AD), and the increasing level of concern they have generated, subjective memory complaints (SMCs) are poorly understood. This study investigated the accuracy with which SMC can separate mild cognitive impairment (MCI) and early AD from cognitive normal (CN), and explored whether the discrimination ability is similar to or better than that of the Mini-Mental State Exam (MMSE). Patients and methods: This study recruited 175 CN subjects, 52 with MCI, and 66 with probable AD aged 60 years or older. To test the independent contributions of SMC and MMSE scores to the classification of cognitive status (CN vs MCI or early AD), logistic regression analyses were performed, adjusting for the following potential confounding variables: age, gender, Frontal Assessment Battery score, modified Hachinski Ischemic Scale score, and apolipoprotein E epsilon4 status. Receiver operating characteristic (ROC) curve analyses were used to determine the discrimination accuracy of SMC and MMSE scores, and area under the ROC curve (AUROC) was also calculated. Results: In the highly educated (>=7 years), nondepressed (Geriatric Depression Scale <=15) subgroup, SMC showed good accuracy in discriminating cognitively impaired subjects from CN after adjusting for potential confounding variables (the AUROC of the adjusted SMC was 0.841 for MCI discrimination, and it was 0.858 for MCI plus early AD discrimination). Both SMC and MMSE scores significantly contributed to differentiating between CN and MCI (OR=2.372, 95% CI=1.086-5.177; OR=0.730, 95% CI=0.566-0.941, respectively) after adjusting for the same covariates. However, in the highly educated and nondepressed subgroups, SMC showed significant predictive power for MCI from CN (OR=3.119, 95% CI=1.190 8.176; OR=3.328, 95% CI=1.320-8.396, respectively), whereas MMSE scores did not. Conclusion: Our findings support the usefulness of SMC, which was comparable or even superior to MMSE scores, for detecting MCI or early AD. PMID- 30288044 TI - Risk of hip fracture in patients on dialysis or kidney transplant: a meta analysis of 14 cohort studies. AB - Purpose: We aimed to conduct a meta-analysis of published cohort studies to evaluate the risk of hip fracture in patients undergoing dialysis or kidney transplantation (KT). Methods: We identified relevant studies by searching PubMed, EMBASE and Google Scholar databases from their inception to December 31, 2017. Cohort studies evaluating risk of hip fractures in patients undergoing dialysis or KT were considered included. The methodological quality of the cohort studies was assessed using the modified Newcastle-Ottawa scale. Results: In our meta-analysis of 14 retrospective cohort studies, a total of more than 1.5 million patients undergoing dialysis or KT were included, of whom more than 30,000 had hip fractures. After the merger, the proportion of hip fractures was 1.92% (95% CI, 1.38%-2.46%) with significant heterogeneity (I 2=99.9%, P=0.000) in all patients, and the incidence rate of hip fractures (per 1,000 person-years) was 8.95 (95% CI, 4.05-13.85) with significant heterogeneity (I 2=99.9%, P=0.000). The pooled relative risks (RR) value for dialysis patients compared with the general population were 6.35 (95% CI, 4.53-8.88) for male and 5.57 (95% CI, 4.44-6.99) for female. The pooled RR value for hemodialysis (HD) patients compared with peritoneal dialysis (PD) patients was 1.39 (95% CI, 1.13-1.70) with no heterogeneity (I 2=0.0%, P=0.763). Conclusion: In conclusion, the present meta analysis reveals that about 2% of dialysis or KT patients go on to sustain a hip fracture during follow-up, with the overall hip fracture incidence rates being 8.95 per 1,000 person-years. The overall risk of hip fracture was more than 5 fold higher in dialysis patients than in the general population. Among patients on PD, HD, and KT, HD and KT patients had the highest and the lowest risk of hip fractures, respectively. PMID- 30288042 TI - A drug eluting poly(trimethylene carbonate)/poly(lactic acid)-reinforced nanocomposite for the functional delivery of osteogenic molecules. AB - Background: Poly(trimethylene carbonate) (PTMC) has wide biomedical applications in the field of tissue engineering, due to its biocompatibility and biodegradability features. Its common manufacturing involves photofabrication, such as stereolithography (SLA), which allows the fabrication of complex and controlled structures. Despite the great potential of SLA-fabricated scaffolds, very few examples of PTMC-based drug delivery systems fabricated using photo fabrication can be found ascribed to light-triggered therapeutics instability, degradation, side reaction, binding to the macromers, etc. These concerns severely restrict the development of SLA-fabricated PTMC structures for drug delivery purposes. Methods: In this context, we propose here, as a proof of concept, to load a drug model (dexamethasone) into electrospun fibers of poly(lactic acid), and then to integrate these bioactive fibers into the photo crosslinkable resin of PTMC to produce hybrid films. The hybrid films' properties and drug release profile were characterized; its biological activity was investigated via bone marrow mesenchymal stem cells culture and differentiation assays. Results: The polymer/polymer hybrids exhibit improved properties compared with PTMC-only films, in terms of mechanical performance and drug protection from UV denaturation. We further validated that the dexamethasone preserved its biological activity even after photoreaction within the PTMC/poly(lactic acid) hybrid structures by investigating bone marrow mesenchymal stem cells proliferation and osteogenic differentiation. Conclusion: This study demonstrates the potential of polymer-polymer scaffolds to simultaneously reinforce the mechanical properties of soft matrices and to load sensitive drugs in scaffolds that can be fabricated via additive manufacturing. PMID- 30288045 TI - Changes in cardiovascular risk and clinical outcomes in a HIV/AIDS cohort study over a 1-year period at a specialized clinic in Mexico. AB - Introduction: The third report of the National Cholesterol Education Program guidelines recommends calculating the 10-year morbidity of atherosclerotic cardiovascular disease (ASCVD) using risk calculators when treating high blood cholesterol in adults. We analyzed the changes in cardiovascular risk (CVR) among Mexican patients with HIV. Patients and methods: This observational, prospective cohort study compared the CVR after 1 year of antiretroviral treatment among 460 HIV patients from a Mexican clinic. Changes using the ASCVD risk estimator and changes in clinical outcomes were analyzed. The results were categorized as low or high CVR using a cutoff of 7.5%. Results: The CVR initially had a median of 2.3% (interquartile range [IQR]: 1%-4.8%), which changed to 2.4% (IQR: 1.5%-5.5%) after 1 year (P=0.001). After CVR stratification, we found that 84.3% of the patients had a low CVR, and 18% in this subgroup had metabolic syndrome (MS). Moreover, 15.7% had high CVR, and 47% in this subgroup had MS. The 4.3% of patients had an increase in CVR from the low to high subgroup, and 2.6% had a decrease in CVR from the high to low subgroup. Out of all patients, 22.3% had MS. Conclusion: More than 50% of the population had an increase in CVR after 1 year. Of these patients, 4.3% changed from the low to high CVR group. Although the guidelines proposed different time periods for performing CVR estimations, this study showed that such assessments offered valuable clinical data over a relatively short-term period. PMID- 30288047 TI - Efficacy and safety of apatinib treatment for gastric cancer, hepatocellular carcinoma and non-small cell lung cancer: a meta-analysis. AB - Apatinib (Aitan(r), brand name in China) is a new anti-antiangiogenic agent that has recently been approved for the treatment of advanced gastric cancer (GC) in China. Nevertheless, its therapeutic efficacy against other types of advanced solid tumors remains unclear. This meta-analysis examines the short-term efficacy and safety of apatinib or combination therapy for GC, hepatocellular carcinoma (HCC) and non-small-cell lung cancer (NSCLC); and provides a discussion of its anti-angiogenesis therapy applications. Seven clinical studies met the inclusion criteria. The treatment of cancers using apatinib was more successful compared to therapy without apatinib. Both objective response rates (ORRs) and disease control rates (DCRs) were significantly improved in the apatinib group compared to those in the control group (RR=2.18, 95% CI 1.30-3.65; RR=2.09, 95% CI 1.21 3.60). The DCR of 850 mg qd and 750 mg qd were higher than those in the control group (P<0.05). Based on the short-term acute adverse reactions of apatinib, significant differences between groups were found for hypertension, urine protein, hand foot syndrome, and gastrointestinal reactions (diarrhea), while no significant differences were found for myelosuppression, nausea and vomiting. Moreover, the results showed that apatinib prolonged patient survival (HR=0.38, 95% CI: 0.28-0.52), and the effect was more pronounced in patients treated with 750 mg qd or 850 mg qd of apatinib than in those treated with a dose of <=500 mg qd. Additionally, compared to its second-line application, the third-line application was shown to further reduce the risk ratio in patients. Furthermore, overall survival was longer in patients treated with apatinib. Apatinib was shown to have certain short-term effects and survival benefits on GC, HCC, and NSCLC with controllable adverse effects. PMID- 30288046 TI - Home care workers in heart failure: a systematic review. AB - Background: Home care workers (HCWs), which include home health aides and personal care aides, are increasingly used by heart failure (HF) patients for post-acute care and long-term assistance. Despite their growing presence, they have largely been left out of HF research and interventions. This systematic review was aimed to 1) describe utilization patterns of HCWs by adults with HF, 2) examine the effect of HCWs on HF outcomes, and 3) review HF interventions that involve HCWs. Methods: Five electronic databases (Ovid MEDLINE, Ovid EMBASE, Cochrane Library [Wiley], CINAHL [EBSCO], and AgeLine [EBSCO]) were searched from inception through August 4, 2017. The yield was screened using prespecified inclusion and exclusion criteria. Two authors independently reviewed references and a third reviewer acted as an arbitrator when needed. Data were extracted from articles that met the inclusion criteria. The Downs and Black checklist was used for quality assessment. Due to study heterogeneity, a narrative synthesis was conducted. Results: Of the 7,032 studies screened, 13 underwent full-text review, and six met the inclusion criteria. Two descriptive studies found that adults with HF who live alone and have functional and cognitive deficits utilize HCWs. While three retrospective cohort studies examined the association between having an HCW post-HF hospitalization and readmission rates, their findings were conflicting. One quasi-experimental study found that an HCW-delivered educational intervention improved HF patients' self-care abilities. Overall, despite some significant findings, the studies assessed were of poor-to-fair quality (Downs and Black score range: 10-16 [28 total points]), with most lacking methodological rigor. Conclusion: Although HCWs are quite common, the literature on these paraprofessionals in HF is limited. Given the paucity of research in this area and the low quality of studies reviewed here, additional research is warranted on the potential role of HCWs in HF self-care and on outcomes among adults with HF. PMID- 30288048 TI - Is long interval from neoadjuvant chemoradiotherapy to surgery optimal for rectal cancer in the era of intensity-modulated radiotherapy?: a prospective observational study. AB - Objectives: To evaluate the impact of interval between neoadjuvant chemoradiotherapy (NACRT) and surgery on therapeutic and adverse effects of surgery, and long-term outcome of patients with locally advanced rectal cancer (RC), in the era of intensity-modulated radiotherapy (IMRT). Patients and methods: Patients diagnosed with stage II-III RC and treated with IMRT-based NACRT followed by radical surgery were enrolled consecutively from April 2011 to March 2014. The data of all the patients were collected prospectively and grouped according to their NACRT-to-surgery interval. The therapeutic and adverse effects of surgery, and survivals were compared between the patients with interval <=7 weeks and those with interval >=8 weeks. Results: A total of 231 patients were eligible for analysis, including 106 cases with interval <=7 weeks and 125 cases with interval >=8 weeks. The therapeutic and adverse effects of surgery were similar between these two groups of patients. However, interval >=8 weeks appeared to lead to poorer overall, distant-metastasis-free and disease-free survivals, compared with interval <=7 weeks. The HRs were 1.805, 1.714, and 1.796 (P-values were 0.045, 0.049, and 0.028), respectively. Conclusion: For patients with locally advanced RC, a long NACRT-to-surgery interval might bring a potential risk of increased distant metastasis rather than a better tumor regression in the era of IMRT. PMID- 30288049 TI - Distribution of CD4+ and CD8+ exhausted tumor-infiltrating lymphocytes in molecular subtypes of Chinese breast cancer patients. AB - Purpose: Breast cancer (BC) is the leading cancer affecting Chinese women; however, the immune microenvironment between molecular subtypes is less reported. This study aimed to investigate the distribution of tumor-infiltrating lymphocyte (TIL) subpopulations, especially exhausted CD4+ and CD8+ TILs in Chinese BC patients. Patients and methods: A total of 133 patients with breast invasive ductal carcinoma were recruited consecutively from January 1, 2012 to December 31, 2013, and TILs were detected in H&E-stained sections. Expression profiling of PD-1, CD4, and CD8 was determined by immunohistochemistry on 4 um formalin-fixed paraffin-embedded tissue sections. The distribution of TILs was analyzed based on hormone receptor status and molecular subtypes. Results: PD-1+, CD4+, and CD8+ TILs distributed differently based on molecular subtypes. Compared to Luminal A, triple-negative breast cancer (TNBC) patients had more PD-1+ TILs (39/high-power field [HPF] vs 11/HPF), PD-1+ helper T (CD4+) cells (28/HPF vs 10/HPF), and PD-1+ cytotoxic (CD8+) T-cells (3/HPF vs 2/HPF). Conclusion: TILs are distributed differently based on molecular subtypes. TNBC patients exhibit more PD-1+ exhausted TILs, representing an inhibitory immune microenvironment. PD-1/PD-L1 pathway is a potential therapeutic target of TNBC. PMID- 30288050 TI - Scalp metastases as first presentation of pulmonary adenocarcinomas: a case report. AB - Cutaneous metastasis from primary visceral malignancy is a relatively uncommon clinical entity, with a reported incidence ranging from 0.22% to 12% of all malignancies. Here we report a 64-year-old asymptomatic female patient with Peutz Jeghers syndrome presenting with multiple scalp metastases as the initial manifestation secondary to lung adenocarcinoma. Subsequent lung computed tomography scan showed large masses involving the left upper lobe associated with extensive mediastinal lymphadenopathy. After treatment with an epidermal growth factor receptor inhibitor gefitinib, the size of the tumor in the lung reduced significantly and the condition of the patient also gradually improved. Our case demonstrated that scalp metastasis could be the first sign of an internal malignancy. Asymptomatic elderly patients presenting with multiple, painless, immobile cutaneous nodules should be considered for further investigations to rule out the underlying primary cause. Metastasis to the skin is often a preterminal event that heralds poor prognosis. PMID- 30288051 TI - CPEB4 promotes growth and metastasis of gastric cancer cells via ZEB1-mediated epithelial- mesenchymal transition. AB - Background: Cytoplasmic polyadenylation element-binding protein 4 (CPEB4) has previously been reported to be associated with biological malignancy in various cancers. However, its function in tumor growth and metastasis in gastric cancer (GC) remains obscure. Here, we explored the functional and molecular mechanisms by which CPEB4 influences GC. Materials and methods: The expression of CPEB4 was assessed using Western blot and immunohistochemistry in GC specimens. The roles of CPEB4 in GC cell proliferation, migration, and invasion were investigated by cell-counting kit-8 (CCK-8), colony formation, and EdU assay; wound-healing assay; and transwell assay, respectively. Quantitative real-time PCR (qRT-PCR), Western blot, and immunofluorescence staining were performed to detect the expressions of CPEB4 and epithelial-mesenchymal transition (EMT)-related markers. The function of CPEB4 on GC cell growth and metastasis was also determined in vivo through establishing subcutaneous xenograft tumor and lung metastatic mice model. Results: The results revealed that the expression of CPEB4 was increased in GC tissues compared with matched normal tissues. High expression level of CPEB4 was significantly associated with clinical metastasis and unfavorable prognosis in patients with GC. Furthermore, CPEB4 silencing remarkably inhibited GC cells' proliferation, invasion, and metastasis in vitro and in vivo. Conversely, CPEB4 overexpression achieved the opposite effects. Mechanically, we proved that ZEB1-mediated EMT might be involved in CPEB4-facilitated GC cells' proliferation, invasion, and metastasis. Conclusion: Our findings implied that CPEB4 expression predicted a worse prognosis in patients with GC. Besides, CPEB4 contributed to GC cells' proliferation, migration, and invasion via ZEB1-mediated EMT. PMID- 30288052 TI - Clinical, dosimetric, and position factors for radiation-induced acute esophagitis in intensity-modulated (chemo)radiotherapy for locally advanced non small-cell lung cancer. AB - Purpose: The purpose of this study was to estimate the relation between acute esophagitis (AE) and clinical, dosimetric, and position factors in patients with locally advanced non-small-cell lung cancer (NSCLC) receiving intensity-modulated (chemo)radiotherapy. Materials and methods: A retrospective cohort analysis was performed to identify factors associated with Common Toxicity Criteria for Adverse Events grade 2 or worse AE (AE2+). A multivariable model was established including patient- and treatment-related variables and esophageal dose-volume histogram parameters. The esophagus was divided according to physiological anatomy, and logistic regression was used to analyze the position parameter for its correlation with AE2+. Results: The incidence of AE2+ was 27.5%. All models included gender, concurrent chemo-radiotherapy (CCRT), position parameter, and one of the dosimetric variables. The model with mean dose showed the best goodness of fit. Gender (OR=2.47, P=0.014), CCRT (OR=3.67, P=0.015), mean dose (OR=1.33, P<0.001), and maximum radiation position (OR=1.65, P=0.016) were significantly related to AE2+. Conclusion: Gender, concurrent chemotherapy, maximum radiation position, and mean dose were independent risk factors for AE2+. The upper part of the esophagus showed a higher sensitivity to radiation toxicity. PMID- 30288053 TI - All-trans retinoic acid-encapsulated, CD20 antibody-conjugated poly(lactic-co glycolic acid) nanoparticles effectively target and eliminate melanoma-initiating cells in vitro. AB - Purpose: Melanoma, which is initiated from melanocytes, is the most fatal type of skin cancer. Melanoma-initiating cells significantly contribute to the initiation, metastasis, and recurrence of melanoma, and CD20 is a marker of melanoma-initiating cells. All-trans retinoic acid (ATRA) has been demonstrated to induce differentiation, inhibit proliferation, and promote the apoptosis of cancer cells and cancer-initiating cells (CICs). However, there has been no report on ATRA activity against melanoma-initiating cells. In this study, we examined the activity of ATRA against melanoma-initiating cells and developed ATRA-encapsulated poly(lactic-co-glycolic acid) (PLGA) nanoparticles, which were conjugated with a CD20 antibody (ATRA-PNP-CD20) for targeted delivery of ATRA to CD20+ melanoma-initiating cells. Materials and methods: The effects of ATRA and ATRA-PNP-CD20 against melanoma-initiating cells were investigated using a cytotoxicity assay, tumorsphere formation assay, and flow cytometry. Results: ATRA-PNP-CD20 had a size of 126.9 nm and a negative zeta potential. The drug loading capacity of ATRA-PNP-CD20 was 8.7%, and ATRA-PNP-CD20 displayed a sustained release of ATRA for 144 hours. The results showed that ATRA-PNP-CD20 could effectively and specifically deliver ATRA to CD20+ melanoma-initiating cells, achieving superior inhibitory effects against CD20+ melanoma-initiating cells compared with those of free ATRA and nontargeted nanoparticles. To the best of our knowledge, we report for the first time a potent activity of ATRA against CD20+ melanoma-initiating cells, targeted drug delivery of ATRA via nanoparticles to melanoma-initiating cells, and the achievement of a superior inhibitory effect against melanoma-initiating cells by using a CD20 antibody. Conclusion: ATRA-PNP CD20 represents a promising tool for eliminating melanoma-initiating cells and shows a potential for the therapy of melanoma. PMID- 30288054 TI - Immunotherapy combined with epidermal growth factor receptor-tyrosine kinase inhibitors in non-small-cell lung cancer treatment. AB - In recent years, targeted therapy and immunotherapy have played important roles in the treatment of patients with non-small-cell lung cancer (NSCLC). Drugs that target epidermal growth factor receptor (EGFR) mutations (eg, gefitinib, erlotinib, icotinib, and osimertinib) are among the most commonly used targeted therapies. Afatinib is an irreversible second-generation EGFR-tyrosine kinase inhibitor (EGFR-TKI), and the LUX-Lung 3 trial demonstrated the superiority of afatinib to cisplatin and pemetrexed in the frontline treatment of treatment naive patients with advanced EGFR mutation adenocarcinoma of the lung. Although these drugs show significant therapeutic efficacy, most patients invariably experience disease progression resulting in death. Immunotherapy targeting programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1) has now been approved for the first-line treatment of patients with advanced NSCLC. These can produce sustained clinical responses by reversing negative regulators of T-cell function; however, immunotherapy response rates remain low, and only a few patients ultimately benefit from this approach. Here, we discuss the potential of EGFR TKIs for inducing antitumor immunity and the feasibility of their combination with immunotherapy (including PD-1/PD-L1 inhibitors) in NSCLC patients and the associated challenges for clinical application. PMID- 30288056 TI - CAV2 promotes the growth of renal cell carcinoma through the EGFR/PI3K/Akt pathway. AB - Background: Caveolin-2 (CAV2) is reported to have an important role in cancer. The following study investigated the expression and function of CAV2 in kidney cancer in vitro and in vivo. Materials and methods: Real-time PCR, immunohistochemistry and Western blotting analysis were used to determine CAV2, epidermal growth factor receptor (EGFR), phosphatidylinositol 3-kinase (PI3K) and protein kinase B (Akt) in kidney cancer cell line OS-RC-2 and clinical specimens. The role of CAV2 in maintaining kidney cancer malignant phenotype was examined by wound healing assay, Matrigel invasion assays and mouse orthotopic xenograft model. Results: Higher expression of CAV2 was found in renal cell carcinoma tissue compared to normal tissue. Furthermore, increased expression of CAV2 was associated with cancer progression. Also, silencing of CAV2 inhibited the proliferation, migration and invasion, as well as the expression of EGFR, PI3K and p-Akt in OS-RC-2 cells in vitro, and OS-RC-2 xenograft growth in vivo. Conclusion: Our results revealed that CAV2 promotes the growth of renal cell carcinoma through EGFR/PI3K/Akt pathway. PMID- 30288055 TI - SOX2, a stemness gene, induces progression of NSCLC A549 cells toward anchorage independent growth and chemoresistance to vinblastine. AB - Background: Non-small cell lung cancer (NSCLC) is difficult to treat successfully. This intractability is mainly due to the cancer progressing through invasion, metastasis, chemotherapeutic resistance and relapse. Stemness has been linked to the various steps of cancer progression in a variety of tumors, yet little is known regarding its role in NSCLC. Purpose: In this study, we sought to determine the role of SOX2, a master regulator of pluripotency, in the growth of extracellular matrix (ECM)-detached cells during cancer progression. Methods: We established a three-dimensional (3D) Poly-2-hydroxyethyl methacrylate (poly-HEMA) culture of lung adenocarcinoma (LUAD) A549 cells as an ECM-detached cell growth model and examined the role of stemness genes using siRNA and small molecule inhibitor in comparison to standard two dimensional (2D) culture. Results: In poly-HEMA culture, A549 cells formed substratum-detached spheroids with characteristics of intermediate epithelial to mesenchymal transition (EMT) and exhibited greater expression of SOX2 than did control 2D cells. Knockdown of SOX2 markedly suppressed the growth of A549 cell aggregates in poly-HEMA culture conditions and furthermore increased their sensitivity to the anticancer drug vinblastine with concomitant downregulation of the activity of the anti-apoptotic AKT kinase. Interestingly, a small molecule, RepSox, which replaces SOX2, stimulated A549 cell growth in poly-HEMA 3D culture condition. Conclusion: Our findings strongly indicate that SOX2 contributes to anchorage-independent growth and chemoresistance via its downstream signaling mediator AKT kinase during the disease progression of NSCLC. SOX2 may therefore be an invaluable therapeutic target of NSCLC. PMID- 30288057 TI - MicroRNA-671-3p promotes proliferation and migration of glioma cells via targeting CKAP4. AB - Background and objective: Glioma is one of the most aggressive and malignant cancers originating from the human brain. Increasing evidence suggests that aberrant expression of microRNAs (miRNAs) frequently occurs in glioma and miRNAs are critical regulators of glioma. miR-671 has recently been revealed to be a novel miRNA that plays a vital role in human glioblastoma multiforme. However, the functional role and underlying mechanisms of miR-671-3p require further analysis. Materials and methods: Western blot and fluorescence quantitative PCR were used to assess the expression of cytoskeleton-associated protein 4 (CKAP4) and miR-671-3p, respectively. A Cell Counting Kit-8 (CCK-8) assay and a Boyden chamber assay were used to detect the proliferative and migratory abilities of glioma cells. A luciferase assay was used to determine the target gene of miR-671 3p. Apoptosis was analyzed by flow cytometry. Results: Our results revealed that overexpression of miR-671-3p promoted cell proliferation and migration in vitro. Meanwhile, forced expression of miR-671-3p reduced apoptosis. In contrast, inhibition of miR-671-3p had the opposite effects. We also identified CKAP4 to be a direct target of miR-671-3p. The expression levels of CKAP4 were decreased in clinical samples and inversely correlated with miR-671-3p expression levels. Ectopic expression of CKAP4 reversed the promotive activity of miR-671-3p in the proliferation and migration and enhanced apoptosis. Conclusion: Our study demonstrates that miR-671-3p is a predominant positive regulator of glioma progression, thus providing new insights into the molecular mechanisms of glioma development. The findings suggest that the miR-6713p/CKAP4 axis may serve as a potential therapeutic target or biomarker in glioma. PMID- 30288058 TI - Mechanisms, monitoring, and management of tyrosine kinase inhibitors-associated cardiovascular toxicities. AB - The tyrosine kinase inhibitor (TKI) drug class is a prominently used option in the treatment of various cancers. Safety evaluation of these drugs has shown evidence of cardiotoxicity of varying frequency and severity between agents; concern has led to updated labeling, warning prescribers of such. This review seeks to clarify the present dangers and investigate cardiotoxic mechanisms of action for each discussed TKI. Dasatinib was connected primarily with an incidence of fluid retention, edema, QT prolongation, and pulmonary hypertension in clinical studies. It is theorized that this is due to a combination of off target kinase binding and on-target binding of Bcr-Abl, and less likely, mitochondrial induced apoptosis. Studies showed sorafenib to carry the risk of hypertension, QT prolongation, and myocardial infarction. Proposed mechanisms for these side effects include inhibition of proteins, vascular endothelium growth factor receptor, hERG potassium channels, and the RAF/MERK/ERK pro-survival pathway. Finally, lapatinib showed evidence of decreased left ventricular ejection fraction (LVEF) and QT prolongation in clinical studies. The literature attributes these as side effects of on-target ErbB2 binding leading to mitochondrial induced apoptosis. The concern warranted by these findings is in question. Pooled safety data suggest that the overall risk for cardiotoxicity is minimal in dasatinib and lapatinib. Sorafenib seems to carry a moderate concern. For the discussed agents, recommendations agree that routine monitoring via methods such as electroencephalogram, cardiac biomarkers, and blood pressure is warranted during the course of treatment, in addition to a comprehensive collection of past medical history and risk factors to identify those at heightened risk for cardiovascular events. PMID- 30288059 TI - PLK1 as a potential prognostic marker of gastric cancer through MEK-ERK pathway on PDTX models. AB - Background: PLK1 has been identified as having a great effect on cell division and maintaining genomic stability in mitosis, spindle assembly, and DNA damage response by current studies. Materials and methods: We assessed PLK1 expression in cervical cancer tissues and cells. We have also evaluated the effects of PLK1 on gastric cancer cell proliferation, migration, and apoptosis both in vitro and in vivo. Results: Our results show that PLK1 is overexpressed in gastric cancer tissues and cells. Inhibition of PLK1 contributes cell cycle G2-phase arrest and inhibits the proliferation, migration, and apoptosis of gastric cancer (GC) cells, whereas its overexpression promotes proliferation, migration, and apoptosis in these cells. Moreover, PLK1 inhibition reduces expression of pMEK and pERK. More importantly, in vivo by analyzing tumorigenesis in patient-derived tumor xenograft (PDTX) models, the inhibition of PLK1 activity by BI6727 significantly decreased the volume and weight of the tumors compared with control group (P<0.01). Conclusion: Our results found that PLK1 has a significant impact on the survival of GC cells; it may become a prognostic judge, a potential therapeutic target, and a preventative biomarker of GC.

AB - Background: Non-small-cell lung cancer (NSCLC) is the major leading cause of cancer-related death around the world. The resistance to chemotherapy limits the effects of clinical treatment. The aim of this study was to identify novel mechanisms involved in NSCLC chemoresistance. Materials and methods: We explored the public database and commercial tissue microarray to evaluate the expression of G protein-coupled receptor 35 (GPR35). We established the chemoresistant A549 cell line to further investigate the biological function of GPR35 in vitro and in vivo. Then, we measured the altered signalings that GPR35 knocking down by Western blot assay. Results: We demonstrated that GPR35 expression was significantly elevated in NSCLC tissues and correlated with poor prognosis. GPR35 was upregulated in our in vitro chemoresistance cell model. GPR35 depletion reduced the half maximal inhibitory concentration of chemodrugs and restored the sensitivity both in vitro and in vivo. Mechanically, we found that GPR35-mediated chemoresistance occurred partially via beta-arrestin-2/Akt signaling. Furthermore, inhibition of beta-arrestin-2 or Akt activation could suppress the GPR35 expression and overcome chemoresistance. Conclusion: Our results suggested that GPR35 might serve as a novel therapeutic target to enhance the chemotherapy efficacy in NSCLC. PMID- 30288061 TI - Effect of long non-coding RNA AOC4P on gastrointestinal stromal tumor cells. AB - Objective: In this research, we explored the effect of long non-coding RNA (lncRNA) AOC4P on gastrointestinal stromal tumor (GIST) cells. Materials and methods: The expression of lncRNA AOC4P in tissues was detected by real-time PCR (RT-PCR). The epithelial-mesenchymal transition (EMT)-related proteins in tissues were analyzed by Western blot. The experiment included negative control group (CN), silence AOC4P group (si AOC4P), and silence negative control group (si CT). RT-PCR, MTT, Scratch, Transwell, and Annexin V-FITC methods were used to detect the expression of lncRNA AOC4P, cell proliferation, cell migration ability, cell invasion ability, and apoptosis, respectively. The EMT-related proteins including TGF-beta, ZEB1, Vimentin, Snail, and E-cadherin were analyzed by Western blot. Results: The expression of lncRNA AOC4P and the expression of EMT-related proteins in high-risk GISTs were higher than that in low- and intermediate-risk GISTs (P<0.05). It was revealed that cell proliferative migration and invasive ability in si AOC4P group was decreased than that in CN and si CT groups (P<0.05), and cell apoptosis in si AOC4P group was higher than that in si CT group. The results of Western blot demonstrated that the expression of TGF-beta1, ZEB1, Vimentin, and Snail in si AOC4P group were lower than that in si CT and CN group (P<0.05), and the expression of E-cadherin in si AOC4P group was higher than that in si CT and CN group (P<0.05).

AB - [This corrects the article on p. 1015 in vol. 11, PMID: 30104889.]. PMID- 30288064 TI - Trichosporon dohaense, a rare pathogen of human invasive infections, and literature review. AB - Background: Trichosporon dohaense is a rare fungal species that has not been described in human invasive infections. Patients and methods: In this study, we investigated two T. dohaense isolates from patients with invasive infections in two hospitals in China, as part of the China Hospital Invasive Fungal Surveillance Net (CHIF-NET) program. Both patients were under immunocompromised conditions. Results: On chromogenic agar, T. dohaense isolates were dark blue, similar to the color of Candida. tropicalis, but the characteristic moist colony appearance was quite different from that of T. asahii. The two isolates were misidentified as T. asahii and T. inkin by the VITEK 2 YST system. The rDNA internal transcribed spacer (ITS) region and the D1/D2 domain sequences of the two T. dohaense isolates were 100% identical to T. dohaense type strain CBS10761T. The sequence of the intergenic spacer region-1 also clearly distinguished the species. Of the three matrix-assisted laser desorption/ionization time-of-flight mass spectrometry systems, Bruker Biotyper and Autobio MS correctly identified the two isolates to species level, whereas Vitek MS systems misidentified them as T. ovoides or T. asteroides. Echinocandins exhibited no in vitro activities against the two T. dohaense isolates. In addition, the isolates exhibited intermediate susceptibility to fluconazole (with minimal inhibitory concentrations [MICs] of 8 and 16 ug/mL) and itraconazole, voriconazole, and posaconazole (MICs of 0.25-1 ug/mL). T. dohaense demonstrated susceptibility to amphotericin B with MIC of 1 ug/mL. The MICs of fluconazole and voriconazole in our study were higher than the MIC50 of 62 for T. asahii isolates (4 and 0.064 ug/mL) in the CHIF-NET program. Conclusion: This case study points to a possible emergence of T. dohaense as an opportunistic human invasive fungal pathogen, and the reduced susceptibility should be noted. PMID- 30288065 TI - Widespread amphotericin B-resistant strains of Aspergillus fumigatus in Hamilton, Canada. AB - Purpose: Amphotericin B (AMB) is one of the major antifungal drugs used in the management of aspergillosis and is especially recommended for treating triazole resistant strains of Aspergillus fumigatus. However, relatively little is known about the AMB susceptibility patterns of A. fumigatus in many parts of the world. This study aims to describe the AMB susceptibility patterns in Hamilton, Ontario, Canada. Methods: The in vitro susceptibilities of 195 environmental and clinical A. fumigatus isolates to AMB were tested by the broth microdilution method as per the Clinical and Laboratory Standards Institute's guidelines. Catalase-generated oxygen bubbles trapped by Triton X-100 were used to quantify catalase activity in a representative group of isolates. Results: Of the 195 isolates, 188 (96.4%) had the minimum inhibitory concentration (MIC) of AMB >=2 mg/L, with approximately 80% and 20% of all clinical and environmental isolates having MICs of >= 4 mg/L. Overall, the clinical isolates were less susceptible to AMB than environmental isolates (P-value <0.001). The strain with the highest AMB MIC (16 mg/L) had one of the highest catalase activities. However, there was no correlation between AMB MIC and catalase activity in our sample. Conclusion: The widespread AMB resistance suggests that using AMB in the management of A. fumigatus infections in Hamilton would likely result in treatment failure. Although high catalase activity may have contributed to AMB resistance in some isolates, the mechanism(s) for the observed AMB resistance in Hamilton is unknown and likely complex. PMID- 30288063 TI - Characterization of antimicrobial resistance mechanisms in carbapenem-resistant Pseudomonas aeruginosa carrying IMP variants recovered from a Mexican Hospital. AB - Purpose: Pseudomonas aeruginosa infections in hospitals constitute an important problem due to the increasing multidrug resistance (MDR) and carbapenems resistance. The knowledge of resistance mechanisms in Pseudomonas strains is an important issue for an adequate antimicrobial treatment. Therefore, the objective was to investigate other antimicrobial resistance mechanisms in MDR P. aeruginosa strains carrying bla IMP, make a partial plasmids characterization, and determine if modifications in oprD gene affect the expression of the OprD protein. Methodology: Susceptibility testing was performed by Kirby Bauer and by Minimum Inhibitory Concentration (presence/absence of efflux pump inhibitor); molecular typing by Pulsed-field gel electrophoresis (PFGE), resistance genotyping and integrons by PCR and sequencing; OprD expression by Western blot; plasmid characterization by MOB Typing Technique, molecular size by PFGE-S1; and bla IMP location by Southern blot. Results: Among the 59 studied P. aeruginosa isolates, 41 multidrug resistance and carbapenems resistance isolates were detected and classified in 38 different PFGE patterns. Thirteen strains carried bla IMP; 16 bla GES and four carried both genes. This study centered on the 17 strains har boring bla IMP. New variants of beta-lactamases were identified (bla GES-32, bla IMP-56, bla IMP-62) inside of new arrangements of class 1 integrons. The presence of bla IMP gene was detected in two plasmids in the same strain. The participation of the OprD protein and efflux pumps in the resistance to carbapenems and quinolones is shown. No expression of the porin OprD due to stop codon or IS in the gene was found. Conclusions: This study shows the participation of different resistance mechanisms, which are reflected in the levels of MIC to carbapenems. This is the first report of the presence of three new variants of beta-lactamases inside of new arrangements of class 1 integrons, as well as the presence of two plasmids carrying bla IMP in the same P. aeruginosa strain isolated in a Mexican hospital. PMID- 30288066 TI - Effects of oral probiotic supplementation on gut Lactobacillus and Bifidobacterium populations and the clinical status of low-birth-weight preterm neonates: a multicenter randomized, double-blind, placebo-controlled trial. AB - Aim: Probiotic bacteria administered directly after birth to preterm neonates may improve gastrointestinal function and may reduce the incidence of late-onset sepsis, which is a frequent complication in this group. Purpose: The main objective of this study was to evaluate whether a new probiotic bacterial mixture of Lactobacillus rhamnosus KL53A and Bifidobacterium breve PB04 given to preterm, low-birth-weight neonates would influence composition of their gut microbiota and sepsis rates. Patients and methods: This study was a multicenter, randomized, double-blind, placebo-controlled trial conducted in clinical centers of neonatal care in Poland. A probiotic or placebo preparation was given twice daily to 181 preterm low-birth-weight neonates who were eligible for enteral feeding between July 2012 and July 2013. The probiotic was given to 90 neonates, while placebo was given to 91 neonates. The gut microbiota was monitored by microbiological analysis of stool samples. Sepsis episodes were detected on the basis of clinical and laboratory findings and confirmed by blood cultures. Results: Tested probiotic administration resulted in continuous increase of the Lactobacillus and Bifidobacterium counts in the gut microbiota. The applied tested strains successfully colonized the neonates gut since they were present in over 90% of stool samples, which was confirmed by molecular analysis. Regardless of the study group (probiotic or placebo), B. breve colonization correlated with lower staphylococcal sepsis incidence, which was irrespective of whether probiotics were given. No sepsis case caused by strains included in study probiotic was recorded. Conclusion: Appropriately selected and characterized probiotic bacteria may be safely given to preterm neonates to normalize their distorted gut microbiota and may contribute to lower staphylococcal sepsis rates. PMID- 30288067 TI - Evaluation of blood culture broths with lysis buffer to directly identify specific pathogens by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry methods. AB - Background: Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is now widely used to detect pathogens in clinical settings in Japan. Method: Here, we report the effects of adding lysis buffer in the MALDI-TOF MS method to directly detect bacteria from 3 blood culture systems and compare their detection efficiencies for each pathogen. Results: Blood culture broths from BD, bioMerieux, and Oxoid showed similar detection efficiencies without lysis buffer use and Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa were efficiently detected in all broths when lysis buffer was used. However, Streptococcus pneumoniae was not detected in BD broth when lysis buffer was added. Furthermore, Haemophilus influenzae and Bacteroides fragilis were not detected in all 3 systems when lysis buffer was used. Conclusion: Optimization of blood culture system and lysis buffer is necessary according to each pathogen for direct identification by MALDI-TOF MS methods. PMID- 30288069 TI - Cost-effectiveness analysis of treatment timing considering the future entry of lower-cost generics for hepatitis C. AB - Background: Cost-benefit analyses are crucial to inform treatment policies, particularly when the cost of patented drugs is very high. The cost of patented drugs is the limiting factor in hepatitis C treatment. However, hepatitis C drug costs are expected to fall following patent expiration, due to generic drug introduction. Methods: An existing mathematical model by Shih et al was extended to consider lower-cost future generics in health economic models of hepatitis C. The model compared the cost-effectiveness of treating patients now with patented drugs vs postponing treatment until after patent expiration. Results: For ledipasvir-sofosbuvir, this study finds that it is almost always more cost effective to treat hepatitis C with high-cost patented drugs immediately rather than waiting for patent expiry. For ledipasvir-sofosbuvir, a generic would need to enter the market at <16.40% of the patented price for delayed treatment to be cost effective. The further that patent expiry is in the future, the more cost effective delayed treatment becomes; however, uncertainty about generic pricing and market entry times are also higher if patent expiry is in the distant future. Conclusion: It is more cost effective to treat hepatitis C sooner rather than later, regardless of the stage of the disease, and despite the high cost of patented drugs. However, patented drugs are being produced globally for prices much lower than those seen in the UK. Therefore, negotiation of patented drug prices with pharmaceutical companies may be a crucial step in cost effective treatment of hepatitis C. PMID- 30288068 TI - Phenotypic and genotypic drug sensitivity of Mycobacterium tuberculosis complex isolated from South Omo Zone, Southern Ethiopia. AB - Background: Knowledge of drug-sensitivity patterns of Mycobacterium tuberculosis complex (MTBC) strains isolated from patients is an important aspect of TB control strategy. This study was conducted to evaluate the drug sensitivity of MTBC isolates in South Omo, southern Ethiopia. Materials and methods: A total of 161 MTBC isolates (153 from new cases and eight re-treatment TB cases) were isolated using Lowenstein Jensen medium of which 126 isolates were able to be tested for drug sensitivity by BACTECTMMGITTM 960 system, while all the 161 isolates were tested by GenoType(r) MTBDRplus VER 2.0. Descriptive statistics and logistic regression were used to express and present results. Results: On the basis of MGIT 960 system, the prevalence of mono-resistance was 9.2% (11/119) in the new cases, although neither poly-resistance nor multidrug resistance (MDR) was recorded in these cases. On the basis of GenoType MTBDRplus assay, two of the 153 isolates (1.3%) of the new cases were mono-resistant for rifampicin (RIF) and one of these isolates had known rpoB gene mutation (H526D). One of the eight (12.5%) isolates obtained from the re-treatment cases was MDR with rpoB gene mutation (D516V) and katG gene mutation (S315T2). Taking MGIT 960 system as a gold standard, the sensitivities of the MTBDRplus assay were 33.3%, 100% and 100% for detection of resistance to isoniazid, RIF and MDR, respectively. On the other hand, its specificities were 99.2%, 100% and 100% for detection of resistance to RIF, isoniazid and MDR, respectively. Conclusion: The magnitude of drug resistance was relatively low in the new TB cases of South Omo as compared to the reports from the other regions of the country. This is encouraging and hence the TB Control Program in the Zone should strengthen its program so that the emergence of drug resistance is inhibited. PMID- 30288070 TI - Impact of a pharmacist-led diabetes management on outcomes, utilization, and cost. AB - Purpose: Pharmacist-led medication therapy disease management (MTDM) has shown improvement in clinical outcomes in patients with certain chronic diseases. However, only limited data demonstrating the impact on health care utilization and cost of care are available. This study seeks to evaluate the impact of a pharmacist-led MTDM program on clinical surrogate outcomes, care utilization, and cost of care among patients with diabetes mellitus. Methods: A retrospective cohort study was conducted by utilizing electronic health records and insurance claims data. Patients were identified between February 2011 and December 2014. Data were collected from Geisinger, a large integrated health care system located in Pennsylvania and southern New Jersey. A total of 5,500 patients with diabetes mellitus were identified; 2,750 were enrolled in MTDM and were 1-to-1 propensity score-matched to a comparison cohort not enrolled in a pharmacist-led MTDM program. Results: There were no differences between groups in composite HbA1c, blood pressure, or low-density lipoprotein cholesterol goal attainment at 12 months (12% vs 12%, P=0.53). HbA1c goal was reached more frequently among patients without MTDM compared to those at 12 months (57% vs 51%, P<0.0001). There were no significant differences between the two cohorts in the attainment of blood pressure or low-density lipoprotein cholesterol goals at 12 months. MTDM was associated with reduced all-cause hospitalization rate (-19.6%; P=0.02) as well as increased primary care physician visits (18.5%; P<0.001) and lower average per-member-per-month medical cost (-13%, P=0.027). Conclusion: Despite the lack of impact on the clinical surrogate outcomes, MTDM was associated with lower cost of care and fewer hospitalizations, possibly facilitated by increased monitoring (ie, higher primary care utilization). PMID- 30288071 TI - Alterations in the gene expression of drug and arachidonic acid-metabolizing Cyp450 in the livers of controlled and uncontrolled insulin-dependent diabetic mice. AB - Background: Diabetic patients have lower capacity to metabolize drugs in comparison to normal people. Therefore, the present study aimed to investigate the alterations in gene expression of drug and arachidonic acid metabolizing cytochrome p450s (cyp450s) in the livers of controlled (CDM) and uncontrolled (UDM) insulin-dependent diabetic mice. Methods: Balb/c mice were treated with single dose of streptozocin (240 mg/kg) to induce diabetes and compared with control group, which was treated with citric buffer (pH =4.5). After 3 days, the blood glucose level was measured to confirm the induction of diabetes. Normalization of blood glucose level in diabetic mice was achieved after 0.1 mL/kg Mixtard(r) insulin therapy for more 5 days. Then, the mice livers were isolated to extract RNA and convert it to cDNA. The gene expression of 14 genes, which play a major role in drug and arachidonic acid metabolism, were measured using quantitative real-time polymerase chain reaction technique. Results: It was found that the gene expression was downregulated (ANOVA test, P-value <0.05) in the livers of UDM mice. The most downregulated genes were cyp4a12, cyp1a2, and slc22a1 with more than 10-fold reduction. The livers of CDM mice showed significantly (P-value <0.05) higher levels of mRNA than UDM mice, but still lower than the non-diabetic mice. Conclusion: This study concluded that hepatic gene expression of drug metabolizing and arachidonic acid- cyp450 enzymes is reduced in insulin-dependent diabetic mice, which can explain, at least in part, the variation in drug and fatty acid metabolism between normal and diabetic patients. PMID- 30288072 TI - Assessment of sleep quality and its predictors among patients with diabetes in Jazan, Saudi Arabia. AB - Background: Poor sleep quality is common among patients with diabetes. It is associated with negative physical, psychological, and functional consequences. However, the implicated risk factors of poor sleep quality remain uncertain. Objectives: This study aimed to determine the prevalence of poor sleep quality among patients with diabetes and to investigate the factors associated with the poor sleep quality. Patients and methods: An analytical cross-sectional study of 307 diabetic patients in Jazan, Saudi Arabia was conducted in 2018. A multistage cluster random sampling was used to select the study participants. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Data on patient's characteristics were gathered via patients' interviews, and medical data were collected based on the patients' files. Logistic regression analysis was used to identify the predictors of poor sleep quality. Results: The mean score of PSQI was 5.29+/-2.73. The prevalence of poor sleep quality was 55.4% (95% CI 49.7 60.8). Sociodemographic and clinical factors were significantly associated with poor sleep quality, such as being elderly, female, illiterate, smoker, complications of diabetes, comorbidity, or psychological symptoms. However, female gender was the strongest predictor of reporting poor quality of sleep, OR= 3.69, 95% CI 1.65-8.28 (P<0.001). Conclusion: Poor sleep quality among diabetic patients is a prevalent health problem. Many factors can affect sleep quality. Health care providers may consider routine screening for and address sleep problems among diabetic patients. PMID- 30288073 TI - Obesity and nonalcoholic fatty liver disease: current perspectives. AB - Nonalcoholic fatty liver disease (NAFLD) is rapidly becoming the most common cause of chronic liver disease due to an increase in the prevalence of obesity. The development of NASH leads to an increase in morbidity and mortality. While the first line of treatment is lifestyle modifications, including dietary changes and increased physical activity, there are no approved pharmacological treatment agents for NAFLD and NASH currently. Due to its complex pathophysiology, different pathways are under investigation for drug development with the focus on metabolic pathways, inflammation, and slowing or reversing fibrosis. There are several agents advancing in clinical trials, and promising results have been seen with drugs that affect hepatic steatosis, inflammation, and fibrosis. This review will provide an overview on NAFLD and some of the mechanisms of disease that are being targeted with pharmacologic agents. PMID- 30288074 TI - Developmental origins of health and disease: a new approach for the identification of adults who suffered undernutrition in early life. AB - Background: Undernutrition in early life (UELife) is a condition associated with greater occurrence of chronic diseases in adulthood. Some studies on this relationship have used short stature as indicator of UELife. However, other non nutritional factors can also determine short stature. Depending on the severity of UELife, the human body reacts primarily compromising weight and length gain, but prioritizing brain growth, resulting in disproportionate individuals. Based on this premise, this study aimed to validate a new anthropometric indicator of UELife. Design: Using stature and head circumference data from a probabilistic sample of 3,109 women, the Head-to-Height Index was calculated: HHI = (head * 2.898)/height. A HHI >1.028 (75th percentile) was the best cutoff for predicting obesity (best balance between sensitivity/ specificity, largest area under the receiver operating characteristic curve, and highest correlation coefficient) and was used to define the condition of body disproportionality. The strength of associations with several outcomes was tested for both disproportionality and short stature (height <=25th percentile: 153.1 cm). Results: In adjusted analysis for confounding factors (age, smoking, and education level), the strength of the associations between body disproportionality and the analyzed outcomes was greater than that observed when short stature was used. Respectively, the observed prevalence ratios (95% CI) were (P<0.05 for all comparisons): obesity: 2.61 (2.17-3.15) vs 1.09 (0.92-1.28); abdominal obesity: 2.11 (1.86-2.40) vs 1.42 (1.27- 1.59); high blood pressure: 1.24 (1.02-1.50) vs 0.90 (0.75-1.08); hypercholesterolemia: 2.98 (1.47-6.05) vs 1.65 (0.91-2.99); and hypertriglyceridemia: 1.47 (1.07-2.03) vs 0.91 (0.69-1.21). Conclusion: Body disproportionality is a more accurate indicator of UELife than short stature. While short stature may be genetically determined, a high HHI is due to metabolic adaptations to undernutrition in early life. PMID- 30288075 TI - Beyond photoaging: additional factors involved in the process of skin aging. AB - Studies assessing the impact of extrinsic factors on skin aging have increased during the last with the increase in life expectancy. Although most of the studies are about the sun radiation impact, many factors should be considered in elderly people, beyond environmental conditions. Lifestyle factors, like diet, sleeping, smoking, should be analyzed carefully, as common age-related conditions (menopause, diabetes, pulmonary diseases, etc.). All these factors could accelerate the natural decline of skin structure and functions, possibly affecting the responses to treatments and drugs. This review demonstrates that growing evidence regarding environmental factors that are associated with lifestyle and comorbidities deserve greater attention from researchers and dermatologists and may require new approaches in the management of skin aging. PMID- 30288078 TI - Inflammatory gene mRNA expression in human peripheral blood and its association with colorectal cancer. AB - Objective: The present study planned to investigate the changes in the mRNA expression of inflammatory genes and their association with colorectal cancer (CRC). Our findings could be useful for noninvasive early screening of CRC patients. Patients and methods: Venous blood of 20 CRC cases and 15 healthy controls was collected. The mRNA expression of COX-2, TNF-alpha, NF-kappaB and IL 6 genes was carried out by using real-time polymerase chain reaction. Relative quantification was done to find out the fold change of these genes. Results: The mean age of cases and controls was 55 and 50 years, respectively. The DeltaCt of COX-2, TNF-alpha, NF-kappaB and IL-6 genes was significantly (p < 0.05) lower in cases as compared to controls. Subsequently, the mRNA expression of these genes was, respectively, 3.56-, 3.4-, 1.71- and 3.86-fold higher in CRC cases as compared to controls. Positive correlation of DeltaCt of COX-2 was found with DeltaCt of TNF-alpha (r = 0.461, p = 0.041) and NF-kappaB (r = 0.536, p = 0.015) in CRC cases. The mRNA expression of COX-2 was significantly lower in T2 stage, while mRNA expression of NF-kappaB was significantly lower in both T2 and T3 stages of CRC as compared to T4 stage. Conclusion: The increased mRNA expression of COX-2 along with the high mRNA expression of TNF-alpha, NF-kappaB and IL-6 genes may be associative risk factors for CRC. COX-2 and NF-kappaB genes were more expressed in advanced stages of CRC indicating their role in tumor progression. Our findings support the possible role of blood biomarker in the screening of CRC patients in the early stages. PMID- 30288076 TI - Short-course therapy for diarrhea-predominant irritable bowel syndrome: understanding the mechanism, impact on gut microbiota, and safety and tolerability of rifaximin. AB - Irritable bowel syndrome (IBS) is a common gastrointestinal (GI) disorder characterized by abdominal pain that occurs with defecation or alterations in bowel habits. Further classification is based on the predominant bowel habit: constipation-predominant IBS, diarrhea-predominant IBS (IBS-D), or mixed IBS. The pathogenesis of IBS is unclear and is considered multifactorial in nature. GI dysbiosis, thought to play a role in IBS pathophysiology, has been observed in patients with IBS. Alterations in the gut microbiota are observed in patients with small intestinal bacterial overgrowth, and overgrowth may occur in a subset of patients with IBS. The management of IBS includes therapies targeting the putative factors involved in the pathogenesis of the condition. However, many of these interventions (eg, eluxadoline and alosetron) require long-term, daily administration and have important safety considerations. Agents thought to modulate the gut microbiota (eg, antibiotics and probiotics) have shown potential benefits in clinical studies. However, conventional antibiotics (eg, neomycin) are associated with several adverse events and/or the risk of bacterial antibiotic resistance, and probiotics lack uniformity in composition and consistency of response in patients. Rifaximin, a nonsystemic antibiotic administered as a 2-week course of therapy, has been shown to be safe and efficacious for the treatment of IBS-D. Rifaximin exhibits a favorable benefit-to harm ratio when compared with daily therapies for IBS-D (eg, alosetron and tricyclic antidepressants), and rifaximin was not associated with the emergence of bacterial antibiotic resistance. Thus, short-course therapy with rifaximin is an appropriate treatment option for IBS-D. PMID- 30288077 TI - The role of inflammation in irritable bowel syndrome (IBS). AB - Irritable bowel syndrome (IBS) is a complex, functional gastrointestinal disorder characterized by chronic abdominal pain or discomfort and altered bowel habits. Despite the global prevalence and disease burden of IBS, its underlying pathophysiology remains unclear. Inflammation may play a pathogenic role in IBS. Studies have highlighted the persistence of mucosal inflammation at the microscopic and molecular level in IBS, with increased recruitment of enteroendocrine cells. Substantial overlaps between IBS and inflammatory bowel disease have also been reported. This review thus aimed to discuss the body of evidence pertaining to the presence of mucosal inflammation in IBS, its putative role in the disease process of IBS, and its clinical relevance. Increased mast cell density and activity in the gut may correlate with symptoms of visceral hypersensitivity. As evidenced by patients who develop postinfectious IBS, infective gastroenteritis could cause systemic inflammation and altered microbiome diversity, which in turn perpetuates a cycle of chronic, low-grade, subclinical inflammation. Apart from mucosal inflammation, neuroinflammation is probably involved in the pathophysiology of IBS via the "gut-brain" axis, resulting in altered neuroendocrine pathways and glucocorticoid receptor genes. This gives rise to an overall proinflammatory phenotype and dysregulated hypothalamic-pituitary-adrenal axis and serotonergic (5-HT) functioning, which could, at least in part, account for the symptoms of IBS. Although a definite and reproducible pattern of immune response has yet to be recognized, further research into anti-inflammatories may be of clinical value. PMID- 30288080 TI - Clinical value of a serum anti-PLA2R antibody in the diagnosis and monitoring of primary membranous nephropathy in adults. AB - Objective: To compare the positive rate of anti-PLA2R antibodies in patients with primary membranous nephropathy (PMN), secondary membranous nephropathy (SMN), and non-membrane nephropathy (non-MN); evaluate serum anti-PLA2R antibodies in the diagnosis of PMN; quantify the serum anti-PLA2R antibody levels during the treatment of PMN patients; and evaluate the clinical value of monitoring changes in serum anti-PLA2R antibody quantification levels. Methods: The kidney tissue was collected by kidney biopsy. The expression of PLA2R in glomeruli was detected by immunofluorescence, and ELISA was used to quantify the serum anti-PLA2R antibody. The positive rate of PLA2R expression in renal tissue and positive rate of the anti-PLA2R antibody in the three groups were compared and calculated using a statistical method. The specificity and coincidence rate of anti-PLA2R used in the differential diagnosis of PMN and SMN were evaluated. The clinical value of monitoring changes in serum anti-PLA2R antibody quantification levels was evaluated. Result: The serum levels of the anti-PLA2R antibody were significantly higher in patients with PMN than in patients with SMN and non-MN group. The difference was statistically significant (P<0.05). The serum anti-PLA2R antibody became negative in the complete remission group. The serum anti-PLA2R antibody levels were significantly lower than before treatment in the partial remission group, and the difference was statistically significant (P<0.05). However, in the non-remission group, the serum anti-PLA2R antibody levels remained high. Conclusion: Detection of the serum anti-PLA2R antibody has a high specificity for diagnosing PMN. The change of the serum anti-PLA2R antibody level is closely related to the status of the PMN: if the anti-PLA2R antibody level has decreased, it indicates that the condition has improved; and if the serum anti-PLA2R antibody continues to show high levels of positive or quantitative increase, the condition is not in remission or has relapsed. PMID- 30288081 TI - Renal replacement therapy in patients with acute respiratory distress syndrome: a single-center retrospective study. AB - Background: Patients with acute respiratory distress syndrome (ARDS) who develop acute kidney injury have increased mortality and frequently require renal replacement therapy (RRT). The optimal timing for initiation of RRT after onset of ARDS to improve survival is not known. Methods: We retrospectively reviewed clinical data on patients admitted to our health system over a 2-year period. Individual charts were carefully reviewed to ascertain that patients met the Berlin criteria for ARDS and to categorize RRT utilization. The Kaplan-Meier analysis was conducted to compare early (L48 hours postintubation) versus late (>48 hours postintubation) initiation of RRT. Associations between RRT initiation and mortality were evaluated using Cox proportional hazards regression. Results: A total of 75 patients were identified with ARDS, 95% of whom received RRT. Mortality of patients who required RRT was 56%. The main indications for RRT initiation were fluid overload (75%), metabolic acidosis (64%), and hyperkalemia (33%). The Kaplan-Meier analysis comparing early initiation of RRT to late initiation of RRT showed no survival benefit. Cox proportional hazard models testing the association between timing of RRT initiation with survival and adjusting for sex, race, ethnicity, and Acute Physiology and Chronic Health Evaluation II score did not reach statistical significance (HR=0.94, 95% CI=0.48 1.86). Conclusion: Timing of RRT initiation was not associated with a survival benefit. Prospective study in the utilization and outcomes of RRT in ARDS could assist in optimizing its usage in this population. PMID- 30288082 TI - Effects of ABCB1 rs1045642 polymorphisms on the efficacy and safety of amlodipine therapy in Caucasian patients with stage I-II hypertension. AB - Purpose: The aim of this study was to determine the impact of ABCB1 (MDR1) rs1045642 polymorphisms on the efficacy and safety of amlodipine in Caucasian patients. Patients and methods: The 12-week study included 100 patients. Patients with the newly diagnosed stage I-II hypertension (HT) were recruited to complete genotyping of the rs1045642 single-nucleotide polymorphism (SNP). The study design did not include a control group. Before treatment, all patients either did not undergo antihypertensive treatment at all or did not receive regular antihypertensive therapy. The initial dose was 5 mg/day. Four office blood pressure measurements, two 24-hour noninvasive ambulatory blood pressure measurements, and questionnaires of Tsvetov were used to evaluate the efficacy and safety of amlodipine. Results and conclusion: The highest antihypertensive effect in combination with the lowest incidence of adverse reactions was observed in the TT group, while patients with the CC genotype showed a low antihypertensive effect and the highest incidence of adverse effects. Patients with the CC genotype presented with adverse effects predominantly in the form of edema. A total of 33 patients reached the target blood pressure (SBP <140 mmHg; DBP <90 mmHg): two patients with the CC genotype (12%); 18 patients with the CT genotype (34%); and 13 patients with the TT genotype (43%). The intergroup differences were: CC vs CT, P=0.02; CC vs TT, P=0.02; and CT vs TT, P=0.05. The results of this study indicate the potential of pharmacogenetic testing for rs1045642 SNP when prescribing amlodipine for the first time in Caucasian patients with stage I-II arterial HT. PMID- 30288079 TI - Spotlight on the NLRP3 inflammasome pathway. AB - Inflammation is triggered by a repertoire of receptors detecting infections and damages. Some of these receptors directly bind microbial ligands, while others recognize endogenous molecules exposed under stress conditions, including infections. Most of these receptors can be engaged by a relatively limited number of stimuli. Differently, NLRP3 acts as a broad sensor of cell homeostasis rupture and can be activated downstream of a plethora of stimuli. NLRP3 then assembles a multiprotein platform resulting in caspase-1 activation, which controls, by direct cleavage, the maturation of cytosolic pro-cytokines including pro interleukin-1beta. In addition, caspase-1 processes cytosolic gasdermin-D and unleashes its pore-forming N-terminal domain, leading to the release of mature cytosolic cytokines and alarmins, as well as pyroptotic cell lysis. Accumulating evidences of the aggravating role of NLRP3-mediated inflammation in various highly prevalent human conditions, including diabetes, neurodegenerative and cardiovascular diseases, raises a huge clinical interest. Nevertheless, the molecular mechanism governing NLRP3 activation remains insufficiently understood. In line with the detrimental consequences of NLRP3 activation illustrated by the aforementioned pathologies, this process is tightly regulated. In this review, we address the current understanding of the control of NLRP3 activity which can be divided into two coordinated processes referred to as priming and activation. In particular, we detail the emerging role of NLRP3 post-translational modifications critical in inflammasome assembly regulation. PMID- 30288083 TI - Mini-laparoscopic cholecystectomy with the MiniLap(r) percutaneous surgical system: a series of 32 patients. AB - Background: In recent years, mini-laparoscopic procedures are gaining the preference of most surgeons due to their potentially better surgical outcomes. The Mini Lap Percutaneous Surgical System with MiniGrip(r) Handle is currently the less invasive instrument and can be applied to a wide range of operations. The current paper presents its application on percutaneous laparoscopic cholecystectomy. Materials and methods: From January 2017 to June 2017, 32 patients underwent percutaneous laparoscopic cholecystectomy with the MiniLap(r) system. All operations were performed by the same surgical team. Results: No conversions and no overall complications were reported. Drainage were not necessary. Mean surgical time was 35 minutes, while patients were released in <24 hours after the operation. Conclusion: The MiniLap system with the use of the mini grip handle seems to sustain the benefits of performing laparoscopically. However, further trials should be conducted so as to establish its safety on cholecystectomies. PMID- 30288084 TI - Relapsing fever Borrelia in California: a pilot serological study. AB - Background: Borrelia spirochetes are tick-borne Gram-negative bacteria that cause disease in humans and animals. Although many studies have focused on Borrelia burgdorferi (Bb), the agent of Lyme disease, recent studies have examined the role of Relapsing Fever Borrelia (RFB) in human disease. In this pilot study, we have evaluated serological reactivity against Bb and RFB in patients residing in California. Methods: Serological testing for reactivity to Bb and RFB antigens was performed in 543 patients with suspected tick-borne illness using a Western blot technique. Further evaluation of a subset of 321 patients residing in California was obtained. Serum samples were tested for IgM and IgG antibodies reactive with Bb and RFB, and samples were classified by county of residence according to Bb reactivity alone, RFB reactivity alone, and dual reactivity against Bb and RFB. Seroreactivity was ranked in counties with the highest absolute number and the highest prevalence of positive samples. Results: Of the 543 total serum samples, 32% were positive for Bb, 22% were positive for RFB, and 7% were positive for both Bb and RFB. Of the 321 serum samples from patients residing in California, 33% were positive for Bb, 27% were positive for RFB, and 11% were positive for both Bb and RFB. In the California cohort, the highest rates of positive serological testing for Bb were found in Santa Clara, Alameda, and Contra Costa counties, while the highest rates of positive serological testing for RFB were found in Santa Clara, Alameda, Marin, and San Francisco counties. The highest rates of dual reactivity against Bb and RFB were found in Contra Costa, Alameda, and San Francisco counties. Among the 24 counties with patients who were tested, Bb seropositivity alone was found in four counties, RFB seropositivity alone was found in two counties, and seropositivity for both Bb and RFB was found in 14 counties. Conclusion: Results of this pilot study suggest that seroreactivity against Bb and RFB is widespread in California, and dual exposure to Bb and RFB may complicate the diagnosis of tick-borne disease. Greater awareness of RFB and broader screening for this tick-borne infection is warranted. PMID- 30288085 TI - Pulsed radiofrequency of C2 dorsal root ganglion under ultrasound guidance for chronic migraine: a case report. AB - Chronic migraine is common but difficult to treat. Most patients respond poorly to drugs. Occipital nerve block such as stellate ganglion block is an effective treatment without continuous effect for migraine. Pulsed radiofrequency (PRF) technique has been shown to be effective in relieving headache and prolonging the effect of nerve block. This case report is about a patient who suffered from chronic migraine with occipital pain and was successfully treated with PRF of C2 (axis) dorsal root ganglion (DRG) under ultrasound guidance confirmed by computed tomograpy scan. The patient did not feel headache after 1-year follow-up. This suggests that C2 DRG PRF might be considered as an alternative treatment for chronic migraine with occipital pain. PMID- 30288086 TI - Hypnosis intervention for the management of pain perception during cataract surgery. AB - Objective: To investigate the effectiveness of hypnosis in pain management during cataract surgery. Methods: Male or female patients with bilateral age-related cataract who wished to have both eyes subjected to phacoemulsification surgery were preliminarily admitted. Immediately after the first-eye surgery, each patient was evaluated for pain using the visual analog scale (VAS), and patients with a VAS score >1 were enrolled. By using block randomization, the enrolled patients were allocated to either the treatment group, which received a hypnosis intervention before the scheduled second-eye surgery, or the control group, which did not undergo hypnosis. The levels of anxiety, pain, and cooperation were evaluated independently by the patients and the surgeon. Results: During the intraoperative pain assessment, 5%, 34%, 38%, and 23% of patients in the control group reported experiencing no pain, mild pain, moderate pain, and severe pain, respectively. In contrast, in the hypnosis group, 18%, 56%, 15%, and 11% of patients reported experiencing no pain, mild pain, moderate pain, and severe pain, respectively, which showed significant differences between the groups (P<0.005). The evaluation of anxiety level showed that the mean score in the control group and hypnosis group was 11.77+/-0.32 and 6.64+/-0.21, respectively, revealing a highly significant difference between the two groups (P<0.005). The assessment of patient cooperation showed that only 5% and 18% of patients in the control group and 18% and 36% of patients in the hypnosis group showed excellent and good cooperation, respectively, while 47% of patients in the control group and only 24% of patients in the hypnosis group exhibited poor cooperation, revealing significant differences between the groups (P<0.005). Conclusion: Hypnosis may be considered as an auxiliary measure in cataract surgery, especially for patients who experienced obvious pain during the first-eye surgery. PMID- 30288087 TI - The polytrauma clinical triad in patients with chronic pain after motor vehicle collision. AB - Background: The polytrauma clinical triad (PCT) is a complex disorder composed of three comorbid diagnoses of chronic pain, post-traumatic stress disorder (PTSD), and postconcussion syndrome (PCS). PCT has been documented in veterans returning from deployment, but this is the first report on PCT prevalence in nonmilitary personnel after a motor vehicle collision (MVC). Methods: Data were drawn from routine intake assessments completed by 71 patients referred to a community-based clinic for chronic pain management. All patients completed the post-traumatic stress disorder checklist for the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (PCL-5), and Rivermead Post-Concussion Symptoms Questionnaire (RPQ) during a standardized intake assessment. An additional modified RPQ score was derived to address previously reported symptom overlap between PCS and chronic pain. Results: Standard and modified RPQ scores yielded PCS prevalence rates of 100% and 54.9% in our sample, respectively. Results suggest that a modified RPQ score, limited to visual and vestibular symptoms, may be more useful PCS screening criteria in patients with chronic pain. PTSD screening criteria on the PCL-5 were met by 85.9% of the patients. More than half of the patients referred for chronic pain after MVC met criteria for PCT (52.1%). Patients who met PCT criteria reported worse headache, overall pain, and sleep quality outcomes. Conclusion: Among patients in our sample with chronic pain after MVC, more than half met criteria for PCT. A modified approach to RPQ scoring limited to visual and vestibular symptoms may be required to screen for PCS in these patients. PMID- 30288089 TI - Effects of whole-body electromyostimulation on chronic nonspecific low back pain in adults: a randomized controlled study. AB - Purpose: Low back pain (LBP) is one of the most frequent chronic conditions worldwide. Data from a recent meta-analysis indicated that whole-body electromyostimulation (WB-EMS), a time-effective, joint-friendly, and highly individualized training technology, demonstrated promising effects on LBP; however, methodologic limitations prevent definitive evidence for this result. Thus, the aim of this study was to conduct a randomized controlled WB-EMS trial to determine the corresponding effect on chronic, nonspecific LBP in people with chronic LBP. Patients and methods: Thirty LBP patients, 40-70 years old, were randomly assigned into two groups (WB-EMS: 15; control [CG]: 15). While the nonactive CG maintained their lifestyle, the WB-EMS group completed a 12-week WB EMS protocol (1*20 min/week) with slight movements, specifically dedicated to LBP. Pain intensity and frequency were determined by a 4-week pain diary before and during the last 4 weeks of intervention. Primary study endpoint was average pain intensity at the lumbar spine. Results: At baseline, no group differences apart from nonregular exercise were observed. Mean intensity of LBP decreased significantly in the WB-EMS group (P=0.002) and remained unchanged in the CG (P=0.730), with a significant difference between both groups (P=0.027). Maximum isometric trunk extensors improved significantly in the WB-EMS group (P=0.005), while no significant difference was seen in the CG (P=0.683). In contrast to the significant difference between WB-EMS group and CG for the latter parameter (P=0.038), no intergroup difference was determined for maximum isometric trunk flexors (P=0.091). The WB-EMS group showed a significant increase of this parameter (P=0.003), while no significant change was determined in the CG (P=0.563). Conclusion: WB-EMS is a time-effective training method for reducing chronic nonspecific LBP and increasing maximum trunk strength in people with such complaints. After this promising comparison with a nonactive CG, research needs to be extended to include comparisons with active groups (WB-Vibration, conventional back strengthening). PMID- 30288090 TI - Trends and patterns of analgesic prescribing in Malaysian public hospitals from 2010 to 2016: tramadol predominately used. AB - Purpose: To examine the trends of analgesic prescribing at public tertiary hospital outpatient settings and explore the patterns of their utilization in nonsteroidal anti-inflammatory drugs (NSAIDs), tramadol, and opioid patients. Patients and methods: This cross-sectional study was conducted from 2010 to 2016 using the prescription databases of two tertiary hospitals in Malaysia. Prescriptions for nine NSAIDs (ketoprofen, diclofenac, celecoxib, etoricoxib, ibuprofen, indomethacin, meloxicam, mefenamic acid, and naproxen), tramadol, and five other opioids (morphine, fentanyl, oxycodone, dihydrocodeine, and buprenorphine) were included in this study. Annual number of patients and prescriptions were measured in repeat cross-sectional estimates. Descriptive statistics and linear trend analysis were performed using Stata version 13. Results: A total of 192,747 analgesic prescriptions of the nine NSAIDs, tramadol, and five other opioids were given for 97,227 patients (51.8% NSAIDs patients, 46.6% tramadol patients, and 1.7% opioid patients) from 2010 to 2016. Tramadol (37.9%, n=72,999) was the most frequently prescribed analgesic, followed by ketoprofen (17.5%, n=33,793), diclofenac (16.2%, n=31,180), celecoxib (12.2%, n=23,487), and other NSAIDs (<4.5%). All the analgesics were increased over time except meloxicam, indomethacin, and mefenamic acid. Opioids, primarily morphine (2.2%, n=4,021) and oxycodone (0.5%, n=1,049), were prescribed the least, but the rate of increase was the highest. Conclusion: Tramadol was the most frequently prescribed analgesic in hospital outpatient settings in Malaysia. Opioids were prescribed the least, but noted the highest increase in utilization. PMID- 30288091 TI - Beyond the muscular effects - onabotulinumtoxinA injections for pain control in chronic knee osteoarthritis: a case report. AB - We present a long-standing case of an 88-year-old woman with multiple comorbidities receiving intra-articular Botox(r) (onabotulinumtoxinA) injections for bilateral chronic knee osteoarthritis. She reported improved pain control and function supported by validated outcome measures. PMID- 30288088 TI - Nonsteroidal anti-inflammatory drugs in chronic pain: implications of new data for clinical practice. AB - COX2-selective and nonselective (ns) nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for chronic pain management. There are marked differences in the risk of adverse gastrointestinal (GI) and cardiovascular (CV) events among different NSAIDs. In 2017, publication of two randomized controlled trials and an individual patient-data meta-analysis provided robust data on the relative GI and CV tolerability profiles of currently available NSAIDs. The PRECISION study showed similar CV-event rates with celecoxib vs naproxen and ibuprofen, but GI tolerability was better for celecoxib. In the CONCERN study of high-GI-risk patients, celecoxib was associated with fewer adverse GI-tract events than naproxen. The meta-analysis showed no significant difference between celecoxib and ns-NSAIDs in the rate of acute myocardial infarction, and celecoxib was the only COX2-selective NSAID with a lower risk of adverse CV and GI events vs ns-NSAIDs. These data add to the body of knowledge about the relative tolerability of different NSAIDs and were used to propose an updated treatment algorithm. The decision about whether to use an NSAID and which one should be based on a patient's risk of developing adverse GI and CV events. Lower- and upper-GI-tract events need to be considered. Celecoxib has a better lower-GI tract tolerability profile than ns-NSAIDs plus a proton-pump inhibitor. In addition, the latest data suggest that long-term use of celecoxib 200 mg/day may be appropriate for patients at increased CV risk. PMID- 30288092 TI - Upregulation of the high-affinity choline transporter in colon relieves stress induced hyperalgesia. AB - Background: Irritable bowel syndrome (IBS) is a common disease with hyperalgesia, the mechanisms of which remain elusive. The cholinergic system is known to be involved in pain inhibitory pathways in multiple diseases, and its involvement in IBS is unknown. Objective: We aimed to determine whether high-affinity choline transporter CHT1, a major determinant of the cholinergic signaling capacity, is involved in regulating intestinal sensations associated with stress-induced visceral pain. Materials and methods: An IBS rat model was established by chronic water avoidance stress (WAS). Colonic pathologic alterations were detected by H&E staining. Visceral sensations were determined by scoring the abdominal withdrawal reflex (AWR) and visceromotor response (VMR) magnitude of the electromyogram in response to colorectal distension (CRD). Abdominal mechanical hyperalgesia was assessed by counting the number of withdrawal events evoked by applying von Frey filaments. Real-time PCR, Western blot, and immunostaining were performed to identify CHT1 expression in the colon. Acetylcholine (ACh) secretion was determined by ELISA. Effects of MKC-231, a choline uptake enhancer, on visceral pain were examined. Results: After 10 days of WAS exposure, AWR score and VMR magnitude in response to CRD were significantly enhanced and the number of withdrawal events was elevated. Protein and mRNA levels of CHT1 were considerably increased in the colon after WAS. CHT1 upregulation in the WAS-exposed group was largely abolished by ammonium pyrrolidinedithiocarbamate. The density of CHT1 positive intramuscular cells and enteric neurons in the myenteric plexus was enhanced in WAS-exposed rats. Pharmacologic enhancement of CHT1 activity by MKC 231 gavage could relieve the visceral pain of WAS rats by upregulating CHT1 protein expression and enhancing ACh production. Conclusion: CHT1 may exert an antinociceptive effect in stress-induced visceral pain by modulating ACh synthesis through nuclear factor kappa B signaling. MKC-231 could be used as a potential drug to treat disorders with hyperalgesia. PMID- 30288093 TI - Erector spinae plane block for postoperative analgesia in laparoscopic cholecystectomy: a case report. AB - The Erector Spinae Plane Block (ESP) is a novel regional technique for anesthesia or analgesia. Originally the ESP block was described in 2016 in a case report regarding analgesia intervention for a case of thoracic neuropathic pain. Since then, there has been growing interest and research adding experience about the ESP block as regional anesthetic and analgesic technique. Reviewing the literature about this novel technique in databases like PubMed using the key words "erector spinae plane block" returns approximately 56 publications. So far there is no available big series of cases or reviews regarding the ESP block. The literature is limited to case reports or case series. With the present case we are interested in exploring the efficacy of ESP block as a postoperative analgesic method for laparoscopic cholecystectomy. We describe the case of a 76 year-old female patient scheduled for laparoscopic cholecystectomy. Written informed consent was granted (for procedure and publication of photos). We applied a bilateral ultrasound-guided ESP block at T6 level while the patient was awake before general anesthesia induction. The anesthetic solution we used consisted of 12 mL Ropivacaine 0.375% plus 2 mg dexamethasone (on each side). After the successful administration of the block (observation of the solution spread between transverse process and the erector spinae muscles), general anesthesia was induced and the procedure was started. Procedure and recovery was uneventful with the patient experiencing very good analgesia (NRS pain score 0 up to 6 hours after block placement). The patient presented mild pain (NRS score of 2-3) after 6 hours and requested the "on demand" pain medication (1 g paracetamol IV) only 10 hours after the ESP block (NRS pain score of 4-5). The patient experienced no nausea or vomiting, was mobilized easily about 6 hours after the block and was discharged the next day. This relatively simple and safe block dramatically reduced the amount of IV pain medication we usually administer for the specific procedure. The overall result was increased satisfaction of the patient and avoidance of opioid use. PMID- 30288095 TI - Analgesic efficacy, safety, and tolerability of a long-acting abuse-deterrent formulation of oxycodone for moderate-to-severe chronic low back pain in subjects successfully switched from immediate-release oxycodone. AB - Objectives: This post hoc analysis of data from a randomized, double-blind, placebo-controlled, enriched-enrollment randomized-withdrawal Phase III study evaluated the safety, tolerability, and analgesic efficacy of Oxycodone DETERx extended-release (ER), abuse-deterrent capsules (Xtampza(r) ER) in subjects with chronic low back pain who were successfully transitioned from immediate-release (IR) oxycodone. Methods: Continuous outcomes were analyzed using a mixed-model repeated-measures approach; binomial outcomes were analyzed using chi-squared; and time-to-event outcomes using Kaplan-Meier analyses. Results: A total of 110 subjects previously prescribed IR oxycodone entered the Open-label Titration Phase. Forty-four subjects were randomized to Oxycodone DETERx (n=22) or placebo (n=22) in the 12-week Double-blind Maintenance Phase. Efficacy results in this subgroup showed a statistically significant difference between Oxycodone DETERx and placebo in average pain intensity scores from Randomization Baseline to Week 12 (least squares mean [+/- standard error], -1.88 [0.70]; P=0.0078). Additional efficacy results indicated that Oxycodone DETERx vs placebo was associated with a statistically significant benefit in durability of effect from Week 2 through Week 12 (P<0.01), numbers of subjects with a >=30% (n [%] 10 [45.5%] vs 0 [0%]; P=0.0004) and >=50% (10 [45.5%] vs 0 [0%]; P=0.0004) improvement in pain intensity, longer time-to-exit (P=0.0014), a greater number of subjects who completed the study (14 [63.6%] vs 4 [18.2%]), and less rescue medication use (acetaminophen; mean [SD], 163.5 [337.8] mg) vs 216.2 [377.3] mg). Adverse event profiles were consistent with opioid class effects and results from the original study; Oxycodone DETERx was well tolerated in subjects previously treated with short-acting oxycodone. Conclusions: Oxycodone DETERx resulted in clinically meaningful and statistically significant efficacy in subjects with chronic low back pain who were previously prescribed IR oxycodone and were successfully switched to ER Oxycodone DETERx. PMID- 30288094 TI - Correlation of changes in hemodynamic response as measured by cerebral optical spectrometry with subjective pain ratings in volunteers and patients: a prospective cohort study. AB - Purpose: Noninvasive cerebral optical spectrometry is a promising candidate technology for the objective assessment physiological changes during pain perception. This study's primary objective was to test if there was a significant correlation between the changes in physiological parameters as measured by a cerebral optical spectrometry-based algorithm (real-time objective pain assessment [ROPA]) and subjective pain ratings obtained from volunteers and laboring women. Secondary aims were performance assessment using linear regression and receiver operating curve (ROC) analysis. Patients and methods: Prospective cohort study performed in Human Pain Laboratory and Labor and Delivery Unit. After institutional review board approval, we evaluated ROPA in volunteers undergoing the cold pressor test and in laboring women before and after epidural or combined spinal epidural placement. Linear regression was performed to measure correlations. ROCs and corresponding areas under the ROCs (AUC), as well as Youden's indices, as a measure of diagnostic effectiveness, were calculated. Results: Correlations between numeric rating scale or visual analog scale and ROPA were significant for both volunteers and laboring women. AUCs for both volunteers and laboring women with numeric rating scale and visual analog scale subjective pain ratings as ground truth revealed at least good (AUC: 70%-79%) to excellent (AUC >90%) distinction between clinically meaningful pain severity differentiations (no/mild-moderate-severe). Conclusion: Cerebral Optical Spectrometry-based ROPA significantly correlated with subjectively reported pain in volunteers and laboring women, and could be a useful monitor for clinical circumstances where direct assessment is not available, or to complement patient reported pain scores. PMID- 30288096 TI - Efficacy of preemptive analgesia on acute postoperative pain in children undergoing major orthopedic surgery of the lower extremities. AB - Background: Children undergoing major orthopedic surgery of the lower extremities can experience severe postoperative pain; yet, the ideal postoperative pain management strategy is unknown. Thus, in this patient population, we investigated the effect of intraoperative epidural infusion of local anesthetic on acute postoperative pain and analgesic consumption. Patients and methods: Patients (N=50, 3-12 years) randomly received either ropivacaine 0.15% (preemptive group) or normal saline (control group) as an initial bolus of 0.2 mL/kg, followed by continuous infusion of 0.15 mL/kg/h throughout surgery. Following surgery, patient-controlled epidural analgesia with ropivacaine 0.1% was provided. The main study outcomes were the revised Face, Legs, Activity, Cry, and Consolability pain scores, epidural ropivacaine consumption, and additional analgesic requirements during the first 48 hours postoperatively. Results: Forty-seven patients completed the study, 23 in the preemptive group and 24 in the control group, respectively. The revised Face, Legs, Activity, Cry, and Consolability pain scores were significantly lower in the preemptive group only at 30 minutes after postanesthesia care unit arrival and 6 hours after surgery (median difference -1.0, 95% CI -2.0 to -1.0, P=0.001 and median difference -2.0, 95% CI 3.0 to -1.0, P=0.005, respectively). However, they were not significantly different between the groups at 12, 24, and 48 hours postoperatively. Epidural ropivacaine consumption and additional analgesic requirements throughout 48 hours postoperatively were not significantly different between the groups. Conclusion: Intraoperative epidural infusion of ropivacaine did not demonstrate preemptive analgesic efficacy within 48 hours postoperatively in children undergoing extensive lower limb orthopedic surgery. PMID- 30288098 TI - Plasma ropivacaine concentration after TAP block in a patient with cardiac and renal failure. AB - We report a successful ultrasound-guided transversus abdominis plane (TAP) block as an analgesic option for minor abdominal surgery in a 66-year-old patient with cardiac, respiratory, and renal dysfunction caused by primary systemic amyloidosis. Bilateral TAP blocks with 120 mg (1.8 mg/kg) of ropivacaine provided sufficient intra- and postoperative analgesia for insertion of a continuous ambulatory peritoneal dialysis catheter. However, the plasma concentration of ropivacaine reached a maximum of 2.5 ug/mL at 15 minutes after the TAP block, a concentration that was potentially neurotoxic. Although apparent signs of local anesthetic systemic toxicity (LAST) such as convulsion or changes in an electrocardiogram were not observed, the patient became drowsy after the TAP block, which might be one of the mild symptoms of LAST. A TAP block by itself can thus be an anesthetic option for patients undergoing minor abdominal surgery. However, cardiac and renal dysfunction might influence the pharmacokinetics of a local anesthetic used, and attention should be paid to the possibility of LAST even with a low dose of a local anesthetic for patients with cardiac and renal failure. PMID- 30288097 TI - Exercise as a tool for hypertension and resistant hypertension management: current insights. AB - Although there has been an observed progress in the treatment of hypertension, its prevalence remains elevated and constitutes a leading cause of cardiovascular disease development. Resistant hypertension is a challenge for clinicians, as the available treatment options have reduced success. Physical activity and exercise training play an important role in the management of blood pressure. The importance of physical activity and exercise training as part of a comprehensive lifestyle intervention is acknowledged by several professional organizations in their recommendations/guidelines for the management of arterial hypertension. Aerobic exercise, dynamic resistance exercise, and concurrent training - the combination of dynamic resistance and aerobic exercise training in the same exercise session or on separate days - has been demonstrated to reduce blood pressure and help in the management of hypertension. The present review draws attention to the importance of exercise training in the management of blood pressure in both hypertension and resistant hypertension individuals. PMID- 30288099 TI - Impact of CT slice thickness on volume and dose evaluation during thoracic cancer radiotherapy. AB - Introduction: Accurate delineation of targets and organs at risk (OAR) is required to ensure treatment efficacy and minimize risk of normal tissue toxicity with radiotherapy. Therefore, we evaluated the impacts of computed tomography (CT) slice thickness and reconstruction methods on the volume and dose evaluations of targets and OAR. Patients and methods: Eleven CT datasets from patients with thoracic cancer were included. 3D images with a slice thickness of 2 mm (2-CT) were created automatically. Images of other slice thickness (4-CT, 6 CT, 8-CT, 10-CT) were reconstructed manually by the selected 2D images using two methods; internal tumor information and external CT Reference markers. Structures and plans on 2-CT images, as a reference data, were copied to the reconstructed images. Results: The maximum error of volume was 84.6% for the smallest target in 10-CT, and the maximum error (>=20 cm3) was 10.1%, 14.8% for the two reconstruction methods, internal tumor information and external CT Reference, respectively. Changes in conformity index for a target of <20 cm3 were 5.4% and 17.5% in 8-CT. Changes on V30 and V40 of the heart were considerable. In the internal tumor information method, volumes of hearts decreased by 3.2% in 6-CT, while V30 and V40 increased by 18.4% and 46.6%. Conclusion: The image reconstruction method by internal tumor information was less affected by slice thickness than the image reconstruction method by external CT Reference markers. This study suggested that before positioning scanning, the largest section through the target should be determined and the optimal slice thickness should be estimated. PMID- 30288100 TI - Decreased expression of TRIM21 indicates unfavorable outcome and promotes cell growth in breast cancer. AB - Background: Tripartite motif-containing protein 21 (TRIM21), an E3 ubiquitin ligase, has been implicated in autoimmune diseases. Dysregulation of TRIM21 contributes to the progression of human malignancies, but its role and clinical significance in breast cancer remain unclear. Methods: The expression of TRIM21 was examined by quantitative real-time PCR, Western blot, and immunohistochemistry. The role of TRIM21 in the progression of breast cancer was determined using in vitro and in vivo models. The upstream regulation of TRIM21 was investigated by luciferase reporter assay. Results: Here, we showed that TRIM21 expression in breast cancer tissues was decreased at both the mRNA and protein levels in comparison to that in nontumorous tissues. TRIM21 expression was closely associated with tumor size, estrogen receptor, human epidermal growth factor receptor 2, and clinical stage. Low TRIM21 expression was correlated with poor overall and disease-free survival in two independent cohorts containing 1,219 patients with breast cancer. A multivariate Cox regression model suggested TRIM21 as an independent factor for overall survival. In vitro data revealed that TRIM21 expression was suppressed by miR-494-3p directly targeting the 3' untranslated region of TRIM21. Overexpression of TRIM21 impeded cell proliferation and tumor growth in breast cancer, whereas TRIM21 depletion enhanced these capacities. Conclusion: Collectively, our findings indicate that TRIM21 serves as a potential prognostic biomarker and functions as a tumor suppressor in breast cancer. PMID- 30288101 TI - Low expression of VSIG4 is associated with poor prognosis in hepatocellular carcinoma patients with hepatitis B infection. AB - Background: V-set and immunoglobulin domain containing protein 4 (VSIG4) was reported to play an important role in tumorigenesis. However, the expression and clinical relevance in hepatocellular carcinoma (HCC) remain unknown. Materials and methods: First, the mRNA profiles of HCC were screened from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus databases. VSIG4, a differentially expressed gene that has not been reported in HCC, was distinguished. Second, the correlation between VSIG4 expression and the prognosis of HCC patients from TCGA was analyzed. Third, VSIG4 mRNA level was detected in 36 pairs of HCC tissues and 4 HCC cell lines by PCR assay. And finally, prognosis analysis was assessed for 36 HCC patients with different expression levels of VSIG4. Results: Bioinformatics analysis showed that VSIG4 expression was downregulated in HCC tissues, and the expression level of VSIG4 was negatively correlated with serum alpha fetal protein (AFP) level and tumor distant metastasis. Survival analysis of all HCC patients in TCGA indicated that the overall survival and disease-free survival were not significantly associated with VSIG4 expression. However, subgroup analysis showed that in the patients with hepatitis B virus-related HCC, both overall survival and disease-free survival were shorter in the low VSIG4 expression group. Our PCR results further showed that VSIG4 expression was significantly decreased in HCC tissues and HCC cell lines, and the disease-free survival in hepatitis B virus-related HCC patients with low VSIG4 expression was shorter than in those with high VSIG4 expression, which was consistent with the bioinformatics analysis results. Conclusion: Our study suggests that VSIG4 is downregulated in HCC, and low expression of VSIG4 is associated with poor prognosis in hepatitis B virus-related HCC patients. PMID- 30288102 TI - A model combining TNM stage and tumor size shows utility in predicting recurrence among patients with hepatocellular carcinoma after resection. AB - Objective: Hepatocellular carcinoma (HCC) recurrence is a clinical challenge. An accurate prediction system for patients with HCC is needed, since the choice of HCC treatment strategies is very important. Patients and methods: A total of 804 patients with HCC who underwent curative resection at Sun Yat-sen University Cancer Center were included in this study. Demographics, clinicopathological data, and follow-up information were collected. Results: A logistic regression analysis was conducted to investigate the relationships between clinical features and HCC recurrence. Tumor size (OR=1.454, 95% CI: 1.047-2.020, P=0.026) and TNM stage (OR=1.360, 95% CI: 1.021-1.813, P=0.036) were independent predictors of HCC recurrence after curative resection. Therefore, the following equation was established to predict HCC recurrence: 0.308*TNM+0.374*tumor size-0.639. The equation score was 0.53+/-0.23 in patients who experienced HCC recurrence compared with 0.47+/-0.24 in other patients. A similar trend was observed in patients who survived after the last follow-up, compared with those who did not, with scores of 0.37+/-0.26 vs 0.52+/-0.22, respectively (P<0.001). The Kaplan Meier analysis showed that patients with HCC with equation values >0.5 had significantly worse outcomes than those with equation values <=0.5 (P<0.001) for overall survival (OS) and recurrence (P=0.043). Multivariate Cox analyses showed that tumor multiplicity (P=0.039), involucrum (P=0.029), vascular invasion (P<0.001), and equation value (P<0.001) were independent prognostic variables for OS, whereas tumor multiplicity (P=0.01), tumor differentiation (P=0.007), vascular invasion (P<0.001), involucrum (P=0.01), and equation value (P<0.001) were independent prognostic variables for HCC recurrence. Conclusion: We established a novel and effective equation for predicting the probability of recurrence and OS after curative resection. Patients with a high recurrence score, based on this equation, should undergo additional high-end imaging examinations. PMID- 30288103 TI - An expression signature model to predict lung adenocarcinoma-specific survival. AB - Background: The current TNM staging system plays a central role in lung adenocarcinoma (LUAD) prognosis. However, it may not adequately stratify the risk of tumor recurrence. With the aid of gene expression profiling, we identified 31 lncRNAs whose expressions in tumor tissues could be used as a risk indicator for the guidance of lung cancer therapy. This exploratory analysis may shed new light on identification of potential prognostic factors. Materials and methods: A survival prediction scoring model was developed from the data that are publicly available in The Cancer Genome Atlas (TCGA) LUAD RNA Sequencing dataset. Multivariate Cox regression analysis and Kaplan-Meier analysis were performed on a cohort of 254 stage I lung carcinoma patients with survival records. Results: Our model indicates that the panels comprising 31 lncRNAs are highly associated with overall survival (OS): 18.9% (95% CI: 10.4%-34.5%) and 89.5% (95% CI: 80.7% 99.2%) for the high- and low-risk group, respectively. The specificity and sensitivity of the model are verified, which show that the area under receiver operating characteristic curve yields 0.881, meaning our model has good accuracy and it is feasible for further applications. Conclusion: The 31-lncRNA model might be able to predict OS in patients with LUAD with high accuracy. Its further applications in biomolecular experiments using clinical samples with independent cohorts of patients are needed to verify the results. PMID- 30288104 TI - Stereotactic radiosurgery for vestibular schwannomas. AB - Stereotactic radiosurgery (SRS) maintains an important role in managing vestibular schwannoma (VS). Long-term clinical data have clearly established the safety and efficacy of the procedure for managing Koos low grade to intermediate grade VS. Historically, the procedure was developed via a multidisciplinary approach that involves physicians (eg, neurosurgeons and radiation oncologists) as well as clinical specialists (eg, radiation physicists). In this paper, we have reviewed current technical and clinical practices of SRS for VS from a procedural specialist's perspective and from a clinician's perspective. PMID- 30288106 TI - S100A9 regulates cisplatin chemosensitivity of squamous cervical cancer cells and related mechanism. AB - Objective: Our previous research has shown that the expression of S100 calcium binding protein A9 (S100A9) in tumor cells was associated with neoadjuvant chemotherapy sensitivity in cervical squamous cell carcinoma. In the present study, we altered the expression of S100A9 through infecting lentivirus, investigated its effect on the chemosensitivity to cisplatin of cervical cancer cells and then made a primary exploration of the involved mechanism. Materials and methods: Lentivirus was employed to upregulate and downregulate S100A9 expression in SiHa cells. The protein expression level of apoptotic-related proteins Bcl-2 and Bax, drug resistance-related proteins multiple drug resistance protein 1 (MRP1), P glycoprotein (P-gp), glutathione-S-transferase-pi (GST-pi), lung resistance-related protein (LRP), and FOXO1 signaling pathway related proteins was detected by Western blot. The CCK-8 assay was used to examine chemosensitivity to cisplatin, and the proportion of apoptosis cells was analyzed by the flow cytometry. Results: S100A9 overexpression could obviously increase the IC50 value of SiHa cells to cisplatin and decrease the apoptosis rate induced by cisplatin. Downregulation of S100A9 led to the opposite results. In S100A9 overexpression SiHa cells, the expression level of Bcl-2, LRP, GST-pi, p-AKT, p ERK, p-FOXO1, and Nanog was significantly increased, while FOXO1 expression was decreased. The opposite results were observed in S100A9 knockdown SiHa cells. Conclusion: Downregulation of S100A9 could significantly increase apoptosis rate, resulting in enhancing sensitivity of SiHa cells to cisplatin, which may be related to Bcl-2, GST-pi, and LRP protein and by altering the AKT/ERK-FOXO1-Nanog signaling pathway. PMID- 30288107 TI - The impact of biopsy sampling errors and the quality of surgical margins on local recurrence and survival in chondrosarcoma. AB - Purpose: To examine the frequency of computed tomography (CT)-guided biopsy sampling errors in chondrosarcomas, as well as the impact of these errors and the achieved surgical margins on local recurrence-free survival (LRFS) and disease specific survival (DSS). Material and methods: A total of 68 consecutive patients treated for chondrosarcoma from 2000-2015 were retrospectively reviewed with a minimum follow-up duration of 2 years. Results: The primary location was at the extremities in 46 patients (67.6%) and at the axial skeleton in 22 patients (32.4%). Seven patients underwent planned intralesional curettage. Surgical margins were assessed in the remaining 53 patients and included 21 wide (39.6%), 25 marginal (47.1%), and seven intralesional (13.2%) resections. Biopsy sampling errors occurred in ten patients (14.7%). LRFS was 82.2+/-7.8% at 5 years and 76.9+/-7.8% at 10 years. An intact anatomical barrier was associated with the most preferable LRFS of 89+/-10.5% after 10 years. DSS was 79.2+/-8.5% at 5 years and 75.5+/-6.4% at 10 years. The metric distance of the surgical margin and the presence of a biopsy sampling error did not affect either LRFS or DSS. Conclusion: Even though histological grading in chondrosarcoma is difficult, sampling errors in preoperative biopsies are relatively rare and do not adversely affect outcomes. The presence of an anatomical barrier has a greater impact on LRFS than the metric distance of the surgical margins. PMID- 30288108 TI - Spotlight on cabozantinib for previously untreated advanced renal cell carcinoma: evidence to date. AB - Background: In the past few years, new drugs made their appearance in the first line setting of treatment for metastatic renal cell carcinoma (mRCC), and cabozantinib is one among them. The present systematic review aims to point out any evidence published to date about first-line treatment with cabozantinib for mRCC patients, describing their outcome in all end points explored by the literature. Methods: PRISMA guidelines were followed. A systematic assessment of literature and peer- reviewed presentations was performed by searching PubMed and major oncology meeting resources, from the database inception until June 25, 2018. The following keywords were used: "cabozantinib or cabozantinib-s-malate or XL184" and "renal cell carcinoma or kidney cancer or clear cell renal carcinoma or renal cancer" and "first-line or untreated or treatment-naive or primary treatment". All types of original clinical studies were included, evaluating either cabozantinib monotherapy or any systemic drug combination containing cabozantinib for previously untreated patients with mRCC. Results: From potential 75 titles and abstracts, seven publications were selected. One was the main report of a randomized clinical trial (the CABOSUN study); four papers reported updated results, secondary or subgroup analyses from the same study population; and further two reports consisted of network meta-analyses. From the additional search for ongoing clinical trials, six studies currently in progress were reported. Conclusion: According to the reported evidence, cabozantinib may be a viable first-line option in mRCC patients with intermediate or poor risk according to International Metastatic Renal Cell Carcinoma Database Consortium model. It offers an undoubtful advantage in terms of progression-free survival, despite quite high rates of G3-4 toxicity, modest objective response rate, and no survival advantage. Nevertheless, given the availability of an immunotherapy combination that significantly improved overall survival for the same population in a Phase III trial and the indisputable efficacy of cabozantinib as second-line treatment, this drug may be devoted as a rescue option in patients progressive to primary therapy. PMID- 30288105 TI - Emerging clinical significance of claudin-7 in colorectal cancer: a review. AB - Tight junctions (TJs) play an important role in maintaining cell polarity and regulating cell permeability. In recent years, many studies have shown that TJ proteins, especially claudin-7, are closely related to inflammation and the development of various malignant tumors. Claudin-7 plays a significant role in maintaining the physiological functions and pathological conditions of the TJ barrier. The dysregulation of claudin-7 plays a tumor suppressor role or conversely has carcinogenic effects in different target tissues or cells, but the exact underlying mechanism is still unclear. In this review, we will summarize the expression pattern of claudin-7 in tumors, focusing on the expression and regulation of claudin-7 in colorectal cancer and discussing the correlation between claudin-7 and invasion, metastasis and epithelial-mesenchymal transition (EMT) in colorectal cancer. The construction of Cldn7-/- mice and conventional claudin-7 knockout mouse models has helped determine the mechanisms by which claudin-7 promotes tumorigenesis. Elucidation of the expression and subcellular localization of claudin-7 under pathological conditions will help develop claudin 7 as a useful biomarker for detecting and diagnosing cancer, and thus may help combat the occurrence, development, and invasion of cancers. PMID- 30288110 TI - Ethylacetate extract from Tetrastigma hemsleyanum inhibits proliferation and induces apoptosis in HepG2 and SMMC-7721 cells. AB - Purpose: This study aimed to investigate the effect of ethylacetate extract from Tetrastigma hemsleyanum (EET) on the proliferation and apoptosis of HepG2 and SMMC-7721 cells and determine the underlying mechanisms. Materials and methods: HepG2 and SMMC-7721 cells were cultured in vitro until the exponential growth phase and then treated with different concentrations of EET for 24 h. We performed a colony forming assay to determine colony forming ability, CCK8 assay to detect cell proliferation, Annexin V-FITC/PI double staining to analyze cell apoptosis, and Western blot to measure the protein expression of Caspase-3, Bcl 2, and Bax. Results: EET significantly inhibited the proliferation of HepG2 and SMMC-7721 cells in a concentration- and time-dependent manner (P<0.05). After treatment with 0, 50, 100, 150, 200, and 250 MUg/mL EET for 24 h, HepG2 the proliferation rates were 100.00%+/-0.00%, 90.33%+/-1.76%, 67.67%+/-0.88%, 47.33%+/-0.88%, 37.00%+/-0.00%, and 30.33%+/-0.67%, respectively, and 100.00%+/ 0.00%, 18.25%+/-1.05%, 19.99%+/-0.59%, 23.42%+/-0.46%, 29.70%+/-0.79%, and 29.8%+/-0.41% for SMMC-7721 cells, respectively. After treatment with 0, 50, 100, 150, 200, and 250 MUg/mL EET for 24 h, the apoptotic rates were 11.08%+/-0.72%, 27.44%+/-0.51%, 32.92%+/-0.41%, 26.20%+/-0.47%, 22.92%+/-0.24%, and 55.60%+/ 0.08%, for HepG2 cells, respectively, and 59.18%+/-0.17%, 41.24%+/-2.05%, 52.54%+/-0.39%, 50.54%+/-1.08%, and 57.44%+/-1.93% for SMMC-7721 cells, respectively. Compared with the treatment groups, the control group showed a significantly lower apoptotic rate (47.91%+/-1.09%, P<0.05). EET at the different concentrations downregulated the protein expression of Caspase-3 in HepG2 cells and upregulated it in SMMC-7721 cells; it also downregulated the protein expression of Bcl-2 in HepG2 and SMMC-7721 cells and upregulated the protein expression of Bax in HepG2 and SMMC-7721 cells. Conclusion: These findings suggest that EET exerts antiproliferative and proapoptotic effects against HepG2 and SMMC-7721 cells mediated by downregulation or upregulation of Caspase-3 expression. Our study may help to develop EET for the pharmacological treatment of hepatoblastoma or hepatocellular carcinoma. PMID- 30288109 TI - Secondhand smoking increases bladder cancer risk in nonsmoking population: a meta analysis. AB - Background: Tobacco smoking has been widely acknowledged to be the most important risk factor for bladder cancer. However, whether secondhand smoking (SHS) increases the risk of bladder cancer still remains uncertain. We conducted a meta analysis about the risk of bladder cancer and lifetime SHS and childhood SHS. Materials and methods: We searched PubMed, EMBASE, Web of Science, and Chinese National Knowledge Infrastructure (CNKI) up to March 12, 2018, and checked references of the retrieved articles and relevant reviews to include 14 studies. Relative risk (RR) and 95% confidence interval (CI) were used to assess this risk. Results: The pooled RR of 14 eligible studies based on the retrieved articles and relevant reviews illustrated a significantly increased risk of bladder cancer with RR 1.22, 95% CI 1.06-1.4. No heterogeneity or publication bias was found. But we need more evidence to prove a more reliable association between childhood SHS and bladder cancer. Conclusion: There was a statistically significant 22% increased risk of bladder cancer for lifetime SHS exposure in nonsmoking patients compared with unexposed nonsmoking population. But the association between childhood SHS exposure compared with unexposed nonsmoking population was unclear. Further research should be conducted to confirm our findings and reveal the potential biological mechanisms. PMID- 30288111 TI - Polymorphisms in AURKA and AURKB are associated with the survival of triple negative breast cancer patients treated with taxane-based adjuvant chemotherapy. AB - Purpose: Triple-negative breast cancer (TNBC) is more than a single disease. Identifying biomarkers to further subdivide TNBC patients with distinct outcome is of great importance. It has been reported that single-nucleotide polymorphisms (SNPs) in Aurora kinase A (AURKA) or Aurora kinase B (AURKB) are associated with the risk and survival of several cancers. But till now, there is no research about these polymorphisms in TNBC patients. Materials and methods: In this study, we investigated the association between polymorphisms in AURKA or AURKB gene and prognosis of TNBC patients treated with taxane-based adjuvant chemotherapy. A total of 273 TNBC patients were enrolled. Haploview 4.2 software was used to identify Tag SNPs. Genotyping was conducted using the MassARRAY MALDI-TOF system. Results: We found that AURKA rs6099128 GG genotype carriers had significantly worse overall survival (OS) than TT+ TG genotype carriers (P = 0.003, HR = 12.499, 95% CI = 2.357-66.298). AURKB rs11651993 TT genotype carriers had better disease-free survival (DFS) than TC + CC genotype carriers (P = 0.018, HR = 1.876, 95% CI = 1.116-3.154). AURKB rs2289590 CC genotype carriers had worse DFS than CA + AA genotype carriers (P = 0.021, HR = 0.536, 95% CI = 0.315-0.912). After subgroup analysis, rs11651993 TC + CC genotype predicted worse DFS in subgroups of age <= 50, post-menopausal, grade unknown (UK), tumor size >2 cm, and lymph node negative. Rs2289590 CA + AA genotype could predict favorable DFS in pre-menopausal, grade 3 and lymph node-positive patients. Conclusion: We first demonstrated that polymorphisms in AURKA or AURKB gene might predict the OS or DFS of TNBC patients treated with taxane-based adjuvant chemotherapy. PMID- 30288112 TI - Efficacy and safety of de-escalation bone- modifying agents for cancer patients with bone metastases: a systematic review and meta-analysis. AB - Background: Compared with application of bone-modifying agents (BMAs) every 4 weeks, it is unclear whether 12-weekly de-escalated therapy can be used as a substitute strategy. Methods: A systematic search of PubMed, EMBASE, and the Cochrane Register of Controlled Trials until November 22, 2017, was performed. Randomized controlled trials (RCTs) were included to assess skeletal-related event (SRE) rates, adverse events, and bone turnover biomarkers, comparing 12 weekly de-escalated treatments with standard 4-weekly dosage regimens. Risk ratios (RRs) with 95% CIs were pooled in fixed-effect meta-analyses. Results: A total of eight citations were eligible comprising 2,878 patients: zoledronate (three studies, 2,650 patients), pamidronate (two studies, 68 patients), and denosumab (three studies, 160 patients). Summary RR (0.98; 95% CI 0.87-1.12; P=0.82) for SRE rates between de-escalated and standard arms was produced when seven low risk of bias trials (695 patients) were pooled, and results without statistical significance also appeared in the analysis of adverse events and bone turnover biomarkers. Due to the limited sample size and methodological differences, the data for skeletal morbidity rates (SMRs), time to first SRE, serum C-telopeptide (sCTx) levels, and hypocalcemia were not combined, but systematic review still obtained similar indistinguishableness. Conclusion: In this meta-analysis of randomized clinical trials, the results "appeared" to show non-inferiority of the 12-weekly treatment. Due to the difference in available data, the results for bisphosphonates are more solid than for the receptor activator of nuclear factor-kappaB ligand (RANKL) antibodies. PMID- 30288113 TI - Computed tomography scan efficacy in staging gastric linitis plastica lesion: a retrospective multicentric French study. AB - Background: Computed tomography (CT) scan is a key imaging technique in the staging of gastric adenocarcinoma and therapeutic management of patients. The aim of this study was to evaluate the performance of CT scan in the staging of parietal and metastatic invasion in gastric linitis plastica group. Methods: A retrospective multicentric French study was conducted from January 2006 to December 2015 on patients with no metastatic gastric linitis plastica and operated by gastrec-tomy. A 2/1 matching based on pTNM stage and center was performed. Results: Fifty patients were included in the linitis plastica group and 100 in the control group. Patients from the linitis group were significantly different from those from the control group with a lower age at diagnosis, a more advanced histological lesion, a more frequent undiagnosed peritoneal carcinomatosis, and a higher risk of R1 resection. Sensitivity and specificity of CT scan for the diagnosis of lymph node involvement were 44% and 75%, respectively, in the linitis plastica group and 55% and 60%, respectively, in the control group. The sensitivity and specificity of CT scan for the T3-T4 parietal invasion were 26% and 100%, respectively, in the linitis group and 40% and 72%, respectively, in the control group. Conclusion: CT scan has an equal sensitivity and specificity for the evaluation of lymph node and parietal involvement in gastric adenocarcinoma, including linitis plastica. CT scan remains the cornerstone of preoperative evaluation in gastric adenocarcinoma, including linitis plastica. However, CT presents a lack of sensitivity to diagnose low volume peritoneal carcinomatosis. PMID- 30288114 TI - Multidisciplinary therapy for scirrhous gastric cancer: a retrospective analysis and proposal of new treatment strategy. AB - Background: Scirrhous gastric cancer (SGC) is highly invasive and metastatic because of its interactions with stromal cells, such as fibroblasts and macrophages, and extracellular matrix, leading to a higher incidence of peritoneal metastasis (PM) than other gastric cancers (GCs). Taxane-based intraperitoneal chemotherapy (IPC) is a promising therapy for PM. We retrospectively analyzed outcomes of multidisciplinary therapies that included IPC for SGC. Patients and therapy: Of 1,679 GC patients treated between 1990 and 2012, we analyzed 119 patients who underwent multidisciplinary therapy for SGC. Patients without PM received gastrectomy with lymphadenectomy and resection of involved adjacent organs followed by intraoperative IPC using cisplatin. Patients with PM received chemotherapy using fluorouracil, with or without methotrexate plus IPC using cisplatin before 2000, and S-1 plus IPC using paclitaxel or docetaxel since 2000. Results: Of the 119 patients, 73 (61%) had PM and 63 (53%) had positive peritoneal lavage cytology. Of the 89 gastrectomy patients, 30 (34%) had macroscopic residual tumors (R2). Of the patients treated since 2000, 66 (100%) received S-1 plus taxanes and 44 patients (67%) received taxane-based IPC. Median survival time was significantly longer in the post-2000 group (22.8 months) than in the pre-2000 group (9.5 months). In univariate analysis, lavage cytology, PM, taxane-based IPC, gastrectomy, and R2 resection were significant prognostic factors. However, only R2 resection was an independent prognostic factor in multivariate analysis (hazard ratio: 5.53, 95% CI: 2.05-14.93). Conclusion: As use of taxane-based IPC is not an independent prognostic factor, new multidisciplinary therapies are necessary to avoid R2 resections. PMID- 30288115 TI - Increased derived neutrophil-to-lymphocyte ratio and Breast Imaging-Reporting and Data System classification predict poor survival in patients with non-distant metastatic HER2+ breast cancer treated with neoadjuvant chemotherapy. AB - Introduction: The prognostic role of the derived neutrophil-to-lymphocyte ratio (dNLR) in human patients with HER2+ breast cancer is not well understood. Here, we aimed to investigate the prognostic significance of dNLR in patients with HER2+ breast cancer undergoing neoadjuvant chemotherapy. Methods: A total of 310 patients with non-distant metastatic HER2+ breast cancer who had received neoadjuvant chemotherapy in our hospital from May 2006 to November 2013 were retrospectively included in this study. Kaplan-Meier curves were used to assess overall survival (OS) and disease-free survival (DFS). The Cox regression model was used to evaluate the prognostic value of dNLR and Breast Imaging-Reporting and Data System (BI-RADS) classification, as well as other clinicopathological parameters in patients with HER2+ breast cancer treated with neoadjuvant chemotherapy. Results: We found that dNLR prior to treatment was positively correlated with tumor size, tumor stage, lymphovascular invasion, and histological grade (P<0.05). The median OS of patients with high dNLR and low dNLR were 44.2 and 69.9, respectively (P<0.001), and the median DFS of patients with high dNLR and low dNLR were 15.3 and 22.1 months, respectively (P<0.001). Multivariate analysis showed that dNLR was an independent risk factor for OS (HR =1.726; 95% CI: 1.072-2.662; P=0.009) and DFS (HR =1.658; 95% CI: 1.125-2.426; P=0.026). Moreover, increased BI-RADS classification independently predicted short OS (HR =1.609; 95% CI: 1.216-2.351; P=0.015) and DFS (HR =1.925; 95% CI: 1.526-2.635; P=0.021). Conclusion: dNLR prior to treatment and BI-RADS classification are independent prognostic factors in patients with HER2+ breast cancer receiving neoadjuvant chemotherapy. PMID- 30288116 TI - Metabolic syndrome and the risk of cholangiocarcinoma: a hospital-based case control study in China. AB - Background: Metabolic syndrome is regarded as a risk factor for hepatocellular carcinoma. However, no research has been conducted to investigate the association between metabolic syndrome and cholangiocarcinoma (CCA), especially in the Chinese population. Herein, a hospital-based case-control study was carried out in China to explore the association between metabolic syndrome and CCA risk. Patients and methods: In this study, 303 CCA patients (136 intrahepatic cholangiocarcinoma [ICC] and 167 extrahepatic cholangiocarcinoma [ECC]) were included, who were observed at Peking Union Medical College Hospital (PUMCH), from 2002 to 2014. Healthy controls were randomly selected from the database of PUMPH Health Screening Center. We retrospectively extracted metabolic syndrome and other possible risk factors from clinical records, followed by investigation of the relationship with CCA via calculation of ORs and 95% CIs using logistic regression analysis. Results: Metabolic syndrome was significantly and positively correlated with all CCA subtypes, with adjusted ORs (AORs) of 0.35 (95% CI =0.29 0.42) and 0.29 (95% CI =0.19-0.44) for ICC and ECC, respectively (both P<0.001). Dyslipoproteinemia harbored a stronger relationship with ICC (OR =3.16; 95% CI =2.12-4.71) than ECC (OR =1.87; 95% CI =1.27-2.77), whereas hypertension harbored a stronger association with ECC (OR =3.09; 95% CI =2.09-4.58) than ICC (OR =2.06; 95% CI =1.32-3.21). Obesity was related to both ICC and ECC, with similar ORs, while diabetes was only related to ICC (OR =4.59; 95% CI =2.78-7.58), but not ECC (OR =0.97; 95% CI =0.49-1.94). Conclusion: Metabolic syndrome was significantly related to a 1.86-fold elevated CCA risk. PMID- 30288117 TI - CD44 is overexpressed and correlated with tumor progression in gallbladder cancer. AB - Background: Gallbladder cancer (GBC) is a highly lethal disease and the most common biliary tract malignant tumor with poor prognosis. Accumulating evidence indicates that cluster of differentiation 44 (CD44) is overexpressed in several malignancies and has a crucial role in the development of cancer. However, its expression and function in GBC are unclear. The aim of this study was to explore CD44 expression and its role in GBC. Materials and methods: The expression of CD44 was measured by immunohistochemistry. Tissue microarray analysis was used to confirm the relationship between CD44 expression and clinical outcomes of GBC patients. EDU assay, colony formation assay, cell migration and invasion assay were performed to detect the functions of CD44 in GBC-SD and NOZ transfected with si-RNA. Results: CD44 was overexpressed and associated with poor outcomes in GBC patients. The univariate and multivariate analyses confirmed that elevated CD44 was an independent prognostic factor for the OS of GBC patients. Silencing CD44 could suppress the GBC cell proliferation, migration and invasion in vitro, as well as attenuated cancer stem cell functions. Conclusion: CD44 markedly correlated with aggressive tumor behaviors and contributed to the progression of GBC, which could represent a novel prognostic marker and potential therapeutic target for GBC patients. PMID- 30288118 TI - Young age increases the risk of lymph node positivity in papillary thyroid cancer patients: a SEER data-based study. AB - Introduction: Currently in papillary thyroid cancer (PTC), the correlation between lymph node positivity (LN+) and patient's age at diagnosis is still inconclusive. The aim of this study was to investigate whether younger PTC patients had higher LN+ rates. Patients and methods: From the 1998-2013 Surveillance, Epidemiology, and End Results database, we analyzed PTC patients with at least 1 LN examined. The patients were divided into 5 groups by age separately for each T stage: <=30; 31-40; 41-50; 51-60; >60 years. Results: A total of 46,077 PTC patients were identified, including 8,386 (18.2%) patients aged <=30 years, 10,971 (23.8%) patients aged 31-40 years, 11,646 (25.3%) patients aged 41-50 years, 8,596 (18.7%) patients aged 51-60 years, and 6,478 (14.1%) patients aged >60 years. In each T stage, LN+ rates were inversely associated with age at diagnosis, which was validated by multivariate logistic regression analysis (p<0.001). In addition, the subset of patients 30 or younger had the highest lymph node ratio compared with other subsets (p<0.001). Conclusion: We identified that younger PTC patients have an increased predisposition for LN+ regardless of T stage. This finding could help surgeons to select the optimal treatment for younger PTC patients. PMID- 30288119 TI - Incidence and distribution of advanced colorectal adenomas in patients undergoing colonoscopy for screening, surveillance, and symptoms. AB - Purpose: The aim of the study was to determine the frequency and distribution of advanced colorectal adenomas (ACAs) in Chinese population. Methods: The patients who were referred to receive a colonoscopy were divided into three subgroups of screening, surveillance, and symptomatic, and then they were selected based on their indications. The symptomatic subgroup was further broken down into the alarm and non-alarm categories. The location and morphology of all colorectal lesions were both investigated and recorded. Results: There were significantly more patients with ACAs in the symptomatic subgroup compared to the screening or surveillance subgroup (11.0% vs 4.1%, P<0.001; 11.0% vs 4.6%, P=0.006). No differences were found in the ACA frequency between the alarm and non-alarm categories (11.7% vs 9.7%, P=0.056). One observation was that in the symptomatic subgroup, distal lesions were more likely to contain ACAs than proximal ones (OR 1.50, 95% CI 1.05-2.15, P=0.024). It was also noted that nonpolypoid lesions had significantly higher amounts of ACAs in the symptomatic subgroup (OR 2.09, 95% CI 1.48-2.94, P<0.001) than the other groups. Conclusion: The incidence of ACAs was higher in patients undergoing a colonoscopy due to their symptoms, compared to the incidence in those who underwent the procedure for screening or surveillance purposes. Additionally, more attention should be focused on distal and nonpolypoid lesions to improve the detection rate of ACAs. PMID- 30288120 TI - CircZNF609 promotes breast cancer cell growth, migration, and invasion by elevating p70S6K1 via sponging miR-145-5p. AB - Background: Accumulating evidence suggests that circular RNAs (circRNAs) play critical roles in carcinomas. However, the contributions of circRNAs to breast cancer remain unclear. Herein, we determined the role of circZNF609 in breast cancer. Methods: A total of 143 breast cancer and 38 normal tissues were collected to assess the expression of circZNF609 and its relationship with breast cancer prognosis. A series of in vitro and in vivo functional experiments were carried out to elucidate the role of circZNF609 in breast cancer progression and its underlying molecular mechanisms. Results: CircZNF609 was markedly over expressed in breast cancer tissues and cell lines, and high circZNF609 expression was closely associated with poor outcome. Silencing of circZNF609 inhibited the malignant phenotype of breast cancer in vitro and in vivo. Mechanistically, circ ZNF609 served as a sponge of miR-145-5p to elevate p70S6K1 expression. Moreover, miR-145-5p overexpression or p70S6K1 knockdown abrogated the oncogenic effects of circZNF609 in breast cancer. In addition, clinically, a strong negative correlation was observed between the expression of circZNF609 and miR-145-5p in breast cancer tissues (r=-0.597, P<0.001), whereas a positive correlation between circZNF609 and p70S6K1 expression (r=0.319, P<0.001). Conclusion: These data suggest that circZNF609 contributes to breast cancer progression, at least partly, by modulating the miR-145-5p/p70S6K1 axis, and it may be a potential therapeutic target for breast cancer. PMID- 30288121 TI - First-line treatment strategies for newly diagnosed chronic myeloid leukemia: a network meta-analysis. AB - Objectives: With bosutinib proven to be available for frontline treatment, there are currently four frontline treatments as well as an additional strategy with high-dose imatinib for newly diagnosed chronic myeloid leukemia (CML). Due to the lack of direct comparison of high-dose imatinib, dasatinib, nilotinib, and bosutinib, we summarized the evidence to indirectly compare the efficacy among these treatment options. Methods: In total, 14 randomized clinical trials including 5,630 patients were analyzed by direct and mixed-treatment comparisons. Outcomes assessed were the following: complete cytogenetic response at 12 months; major molecular response at 12, 24, and 36 months; deep molecular response at 12, 24, 36, and 60 months; early molecular response at 3 months; progression-free survival (PFS); overall survival (OS); and Grade 3 or 4 adverse events (AEs). Results: The Bayesian network meta-analysis demonstrated that high-dose imatinib was less effective than all new-generation tyrosine kinase inhibitors and had a higher probability of Grade 3 or 4 AEs. For molecular response, 300 mg of nilotinib was likely to be the preferred frontline treatment, as demonstrated by higher response rates and faster, deeper, and longer molecular response. For PFS and OS, there were high likelihoods (79% and 74%, respectively) that 400 mg of nilotinib was the preferred option. For AEs, standard-dose imatinib has the highest probability (65%) of being the most favorable toxicity profile. Conclusion: Considering the efficacy and toxicity profile, it is not recommended to use high-dose imatinib for treatment. This analysis also showed that nilotinib has the highest probability to become the preferred frontline agents for treating CML. PMID- 30288122 TI - Number of radiotherapy treatment machines in the population and cancer mortality: an ecological study. AB - Objectives: The aim of this study was to assess the association between the number of radiotherapy treatment machines (RTMs) in the population and incidence adjusted cancer mortality. Methods: Data on cancer incidence and mortality were obtained from the GLOBOCAN project (only high-quality data, C3, or higher according to GLOBOCAN quality label), information on the number of RTMs from the Directory of Radiotherapy Centers database, and remaining data from the World Bank and World Health Organization database. We used linear regression models to assess the associations between RTM per 10,000,000 inhabitants (logarithmized) and the log-transformed mortality/incidence ratio. Models were adjusted for public health variables. To assess the bias due to unobserved confounders, mortality from leukemia was considered as a negative control. Here radiotherapy treatment is less frequently applied, but a common set of confounders is shared with cancer types where radiotherapy plays a stronger role, enabling us to estimate the bias due to confounding of unmeasured parameters. To assess an exposure-effect size relationship, estimated cancer type-specific estimates were related to the proportion of subjects receiving radiotherapy. Results: We found an inverse linear relationship between RTM in the population and the cancer mortality to incidence ratio for prostate cancer (14.1% per doubling of RTM; 95% CI: 0.1%-26.1%), female breast cancer (12.3%; 95% CI: 2.7%-20.9%), and lung cancer in women (11.2%; 95% CI: 4.3%-17.6%). There was no evidence for bias due to unobserved confounders after covariate adjustment. For women, an exposure effect size relationship was found (P=0.02). Conclusion: In this ecological study, we found evidence that the population density of RTM is related to cancer mortality independently of other public health parameters. PMID- 30288123 TI - Determinants of incident asthma-COPD overlap: a prospective study of 55,110 middle-aged adults. AB - Background and aim: Knowledge of the impact of social determinants driving asthma chronic obstructive pulmonary disease overlap (ACO) is lacking. Our objective was to identify determinants of incident ACO. Methods: A total of 55,053 adults (50-64 years) enrolled in the Danish Diet, Cancer, and Health cohort (1993-97) was followed in the National Patient Registry for admissions for asthma (DJ45-46) and chronic obstructive pulmonary disease (COPD; DJ40-44) and vital status. Incident ACO was defined as at least one hospital admission for both asthma and COPD (different time points, one after baseline). Detailed case history was obtained at baseline. Cox proportional hazards model was used to examine associations between possible determinants and incident ACO, in terms of hazard ratio (HR) and 95% confidence interval (CI). Results: During follow-up, 561 incident cases of ACO were identified. Age (HR 4.4, 95% CI 3.3-5.9, age group 60 65 years), current smoking (HR 3.6, 95% CI 2.8-4.6), unemployment (HR 1.5, 95% CI 1.2-1.8), and being divorced (HR 1.5, 95% CI 1.2-1.9) determined a higher risk of incident ACO, whereas the opposite was found for leisure-time physical activity (HR 0.7, 95% CI 0.6-0.8) and high educational level (HR 0.7, 95% CI 0.5-0.9). In contrast to ACO, preexisting myocardial infarction (MI; HR 1.5, 95% CI 1.2-1.8) and stroke (HR 1.5, 95% CI 1.2-1.9) were associated with a higher risk of COPD. Conclusion: Incident ACO is to a large extent determined by factors related to lifestyle and socioeconomic status. PMID- 30288124 TI - Use of bone-modifying agents among breast cancer patients with bone metastasis: evidence from oncology practices in the US. AB - Purpose: Bone-modifying agents (BMAs) are recommended for women with bone metastasis from breast cancer to prevent skeletal-related events. We examined the usage patterns and identified the factors associated with the use of BMAs (denosumab and intravenous bisphosphonates) among women in the US. Patients and methods: Electronic health records from oncology clinics were used to identify women diagnosed with bone metastasis from breast cancer between 2013 and 2014. Patients were excluded if they had recently used a BMA or had concurrent cancer at an additional primary site. The incidence of BMA initiation, interruption, and reinitiation were estimated using competing risk regression models. A generalized linear model was used to estimate risk factors for treatment initiation and interruption. Results: There were 589 women diagnosed with bone metastasis from breast cancer. By 1 year, 68% of these patients (95% CI: 64%, 71%) had initiated treatment with a BMA. Denosumab and zoledronic acid were the most commonly used agents, whereas pamidronate was used infrequently. Young women were more likely to initiate a BMA than older women (adjusted risk difference: 6.4 [95% CI: 1.5, 10.9]). Of the 412 patients who initiated a BMA, 46% (95% CI: 41%, 51%) experienced an interruption within 1 year. Seventy-four percent (95% CI: 68%, 79%) of patients who interrupted their treatment had reinitiated therapy within 1 year of interruption. Conclusion: The majority of women diagnosed with bone metastasis from breast cancer initiate a BMA within 1 year of diagnosis, but a large proportion, particularly among the elderly, do not use these therapies. PMID- 30288125 TI - Locating the second mesiobuccal canal in maxillary molars: challenges and solutions. AB - The second mesiobuccal canal in mesiobuccal roots in maxillary molars is a common finding in root canal treatments. Failure on the location of these canals is associated with a high rate of unsuccessful treatments of maxillary molars. Its prevalence has been assessed in several in vitro and in vivo studies, presenting variations according to the methodology applied, along with the population of interest. While the anatomy of these teeth is well defined in micro-computed tomography studies, the clinical management is a great challenge for the practitioner. The use of a dental operating microscope has rendered a better clinical outcome when considering the location and treatment of this canal. On the other hand, cone-beam computed tomography use is still controversial in the efficacy of MB2 canal location. The association of a dental operating microscope with troughing performed with ultrasonic tips is an essential step in this location. Moreover, sodium fluorescein might be applied for root canal location. Due to the high rate of unsuccessful cases when the MB2 canal is not initially found, several cases are performed aiming to address the cases of missed MB2 canals. Therefore, the clinician should discuss the best possible approach, whether surgical or clinical. This article presents an overview of the importance of the MB2 canal on the outcomes of root canal treatments of maxillary molars. Solutions based in current literature will be presented accordingly. PMID- 30288126 TI - Seroprevalence of Toxoplasma gondii and its associated risk factors among women of reproductive age in Saudi Arabia: a systematic review and meta-analysis. AB - Toxoplasma gondii (T. gondii), which infects many warm-blooded animals including humans, causes toxoplasmosis, a globally widespread condition. To date, no research has explored the overall T. gondii infection seroprevalence among women in Saudi Arabia, nor have the risk factors associated with the infection been examined in the Saudi Arabian context. The present systematic review and meta analysis therefore aimed to investigate toxoplasmosis seroprevalence based on previous study samples of Saudi women of reproductive age, and to establish the potentially risk factors in this national context. PubMed, Science Direct, and Scopus were searched for studies on T. gondii seroprevalence among women in mainland Saudi Arabia published between January 2000 and December 2017. Seroprevalence with 95% CI was presented for each study, and point estimates and their 95% CIs of pooled seroprevalence were then calculated. Twenty papers were eligible for inclusion, with samples totaling 13,597 females of childbearing age (ie, between 15 and 49 years) covering various regions of Saudi Arabia. The pooled estimation for T. gondii prevalence using a random-effect model was calculated as 27.8% (95% CI =20.6%-36.3%). A significant association was observed between age and T. gondii seroprevalence. This review represents the first comprehensive and systematic evaluation of T. gondii infection seroprevalence among Saudi Arabian women, and reports a high prevalence of Toxoplasma infection. Further research is required to support the development of more cost-effective preventive strategies. PMID- 30288128 TI - Gradual spontaneous resolution of corneal bloodstaining after anterior chamber irrigation for rebleeding secondary to traumatic hyphema. AB - Corneal bloodstaining, which is brown or dark yellow in color, is induced by hemoglobin deposition, and its breakdown products extend into the corneal stroma. In this article, we report a rare case of corneal bloodstaining induced by total hyphema after rebleeding for traumatic hyphema. The patient underwent irrigation of the anterior chamber (AC) and cataract surgery of the right eye after trauma. After oral and topical treatment the imprint of corneal bloodstaining faded, and it nearly disappeared after the procedures. Corneal bloodstaining is undoubtedly a vision-threatening complication of total hyphema after ocular trauma, surgical intervention, and even rebleeding. Removal of the total hyphema as soon as possible decreases the severity of corneal bloodstaining, shortens the course of spontaneous healing, and thus improves vision. PMID- 30288127 TI - A randomized controlled pilot trial of a smoking cessation intervention for US women living with HIV: telephone-based video call vs voice call. AB - Background: People living with HIV smoke at a rate three times that of the general population. This randomized controlled pilot trial tested the feasibility and acceptability of a video-call smoking cessation intervention in women living with HIV and its preliminary efficacy compared with a voice-call smoking cessation intervention. The study focused on women due to a paucity of studies among this population, and women are less likely than men to quit smoking when provided with conventional treatment. Methods: Participants in both arms received an HIV-tailored smoking cessation intervention comprising eight 30-minute weekly counseling sessions in conjunction with active nicotine patches for 8 weeks. The only difference between the two arms was the delivery mode of the intervention: via either telephone-based video or voice call. Survival analysis and a Cox proportional hazard regression model were performed to identify factors predicting 6-month prolonged abstinence from smoking. Results: A video-call intervention was almost 30% less feasible than a voice-call intervention because women in their 50s and 60s or poorer women living in some southern states did not have access to video-call equipment. However, those who received the video-call intervention were more likely to complete the study than those who had the voice call intervention. There was no difference in the acceptability of the two interventions. A survival analysis revealed that those in the video arm were significantly more likely to maintain smoking abstinence over the 6-month follow up period than those in the voice arm (log rank chi 2=4.02, P<0.05). Conclusion: Although a video-call intervention is less feasible than a voice-call intervention, the former seems to outperform the latter in achieving long-term smoking abstinence for women living with HIV, which may offer an advantage over establishing therapeutic alliance and visually monitoring their adherence to nicotine patches. Clinical trial registration: ClinicalTrials.gov NCT02898597. PMID- 30288129 TI - Targeting EGFR and uPAR on human rhabdomyosarcoma, osteosarcoma, and ovarian adenocarcinoma with a bispecific ligand-directed toxin. AB - Purpose: Human sarcomas are rare and difficult to treat cancerous tumors typically arising from soft tissue or bone. Conversely, carcinomas are the most common cancer subtype in humans and the primary cause of mortality across all cancer patients. While conventional therapeutic modalities can prolong disease free intervals and survival in some cases, treatment of refractory or recurrent solid tumors is challenging, and tumor-related mortality remains unacceptably high. The identification of overexpressed cell surface receptors on sarcoma and carcinoma cells has provided a valuable tool to develop targeted toxins as an alternative anticancer strategy. Recent investigation of recombinant protein linked toxins that specifically target these cancer receptors has led to the development of highly specific, cytotoxic, and deimmunized drugs that can kill cancer cells. Methods: This study investigated a recombinant protein called epidermal growth factor bispecific angiotoxin (eBAT), which is designed to target the epidermal growth factor receptor (EGFR) on cancer cells and the urokinase plasminogen activator receptor (uPAR) on cancer cells and associated tumor vasculature. Both receptors are expressed by a variety of human sarcomas and carcinomas. Flow cytometry techniques were used to determine binding affinity of eBAT to cancer cells, and proliferation assays were performed to calculate tumor killing ability based on half-maximal inhibitory concentrations. Results: eBAT demonstrated cytotoxicity against a variety of sarcoma and carcinoma cells that overexpress EGFR and uPAR in vitro and showed greater cell killing ability and binding affinity to cancer cells compared with its monospecific counterparts. Conclusion: The results of our study are promising, and further studies will be necessary to confirm the applicability of eBAT as a supplementary therapy for a variety of sarcomas, carcinomas, and possibly other refractory malignancies that express EGFR and uPAR. PMID- 30288130 TI - Using initial serum lactate level in the emergency department to predict the sustained return of spontaneous circulation in nontraumatic out-of-hospital cardiac arrest patients. AB - Objective: To examine the initial level of lactate to predict sustained return of spontaneous circulation (ROSC) in nontraumatic out-of-hospital cardiac arrest (OHCA) patients. Materials and methods: This was a 30-month retrospective cohort study in an emergency department (ED) of a tertiary care hospital. The inclusion criteria were adult nontraumatic OHCA patients who came to the ED with ongoing chest compression. The primary outcome was initial serum lactate level at the ED to predict sustained ROSC in nontraumatic OHCA. Logistic regression was used to determine any association between sustained ROSC and significant variables. Results: There were 207 patients who met the inclusion criteria. Forty one percent of nontraumatic OHCA patients achieved sustained ROSC. The mean +/- SD initial serum lactate in the ROSC group was lower than the non-ROSC group (12.0+/ 4.8 vs 12.6+/-5), but without statistical significance. The significant factors to predict sustained ROSC were no underlying disease (adjusted odds ratio [aOR] 1.71, 95% CI 0.51-5.71, P=0.014), cardiac arrest in a public area (aOR 2.40, 95% CI 1.2-4.79, P=0.013), and witnessed arrest (aOR 2.39, 95% CI 1.26-4.52, P=0.008). The cut-off points of initial serum lactate to predict mortality at 24 and 48 hours after cardiopulmonary resuscitation were 9.1 (P=0.031) and 9.4 (P=0.049) mmol/L, respectively. Eleven survived to hospital discharge, and 54.5% had good neurological outcome without statistical significance (P=0.553). The significant variables and initial lactate levels were used to develop a scoring system which ranged from -4 to 11. The receiver operating characters curve indicated a cut-off point of 3.6 to predict ROSC with an area under the curve of 0.715. Conclusion: The initial serum lactate had no association with sustained ROSC and hospital discharge with good neurological outcome but can be used to predict 24- and 48-hour postresuscitation mortality in nontraumatic OHCA patients with initial serum lactate cut-off points of 9.1 and 9.4 mmol/L, respectively. PMID- 30288131 TI - Using sideline concussion tests in the emergency department. AB - Purpose: Traumatic brain injury (TBI) is a significant cause of death and disability in the United States. Many patients with TBI are initially treated in the emergency department (ED), but there is no evidence-based method of detecting or grading TBI in patients who have normal structural neuroimaging. This study aims to evaluate the validity of two common sideline concussion tests. The Concussion Symptom Severity Score (CSSS) and modified Balance Error Scoring System (mBESS) tests are well-validated sideline tests for concussion, but have not been validated in the setting of non-sport-related concussion, in settings other than the sideline or athletic training room or in moderate or severe TBI. Patients and methods: One hundred forty-eight subjects who had sustained a TBI within the previous 72 hours and 53 healthy control subjects were enrolled. CSSS and mBESS were administered. Clinical outcomes were followed up prospectively. Results: The CSSS was collected in 147 TBI subjects but only 51 TBI subjects were able to complete the mBESS. The CSSS was collected for all 53 control subjects, and the mBESS was completed for 51 control subjects. The mean CSSS for TBI and control subjects was 32.25 and 2.70, respectively (P < 0.001). The average mBESS for TBI and control subjects was 7.43 and 7.20, respectively (P = 0.82). CSSS greater than 5.17 was 93.43% sensitive and 69.84% specific for TBI. Conclusion: The mBESS is poorly tolerated and, among those who can complete the test, not sensitive to TBI in the ED. The CSSS is both sensitive to TBI and well tolerated. PMID- 30288132 TI - Criteria for self-reported quantitative sleep characteristics of individuals who sought medical help for disturbed sleep - a survey of a representative sample of the Swedish population. AB - Background: The public often seeks rule-of-thumb criteria for good or poor sleep, with a particular emphasis on sleep duration, sleep latency, and the number of awakenings each night. However, very few criteria are available. Aim: The present study sought to identify such criteria. Methods: Whether or not a person has sought medical help for sleep problems was selected as an indicator of poor sleep. The group that was studied constituted a representative sample of the general Swedish population (N=1,128), with a response rate of 72.8%. Results: Logistic regression analysis, with an adjustment for age and gender, showed an increased OR for a weekday sleep duration of <=6 hour, (OR >2, and for <5 hour: OR >6). For weekend sleep, the value was <=6 hour (OR >2). For awakenings per night, the critical value was >=2 (OR >2, and for >=5 awakenings: OR >9), and for a sleep latency the critical value was >=30 minutes (OR >2, and for >=45 minutes: OR >6). Adding difficulties falling asleep and early morning awakening (considered qualitative because of the reflected "difficulty"), led to the elimination of all the quantitative variables, except for the number of awakenings. The addition of "negative effects on daytime functioning" and "sleep being a big problem" resulted in the elimination of all the other predictors except age. Conclusion: It was concluded that weekday sleep <=6 hour, >=2 awakenings/night, and a sleep latency of >=30 minutes, can function as criteria for poor sleep, but that qualitative sleep variables take over the role of quantitative ones, probably because they represent the integration of quantitative indicators of sleep. PMID- 30288133 TI - Selecting best-suited "patient-related outcomes" in older people admitted to an acute geriatric or emergency frailty unit and applying quality improvement research to improve patient care. AB - The population is aging worldwide, and hospitals are admitting a higher proportion of acutely unwell older people. Population-specific factors such as multimorbidity and frailty in older people compounded by deficient expertise contribute to longer lengths of stay, higher readmission rates, and increased rates of institutionalization. A wide range of acute geriatric care models are currently providing acute care to frail older people and these have been shown to provide a cost-effective high-quality service. In this review, population specific factors, service models, and a wide range of patient-related outcomes of "at risk" older people admitted to an acute geriatric care unit are explored. In addition, we also discuss data measurements and a quality improvement methodology to improve the delivery of care based on the patient outcome data. We hope, in addition to ensuring effectiveness and sustainability of our current services, this may also enhance academic research. Regular monitoring and evaluation of patient-related clinical outcomes not only improve the patient care and reduce the caregiver burden but also help in implementing quality initiatives to develop existing services. PMID- 30288135 TI - The attitude of blood donors towards the use of their samples and information in biomedical research. AB - Introduction: Blood donation is important for saving human life as blood is used in surgeries, blood transfusion and for clinical use. The mission of blood banks can be extended to include medical research. The objective of the study was to determine and assess the attitude of blood donors in Gaza towards the use of their blood samples and medical data for biomedical research and the associated ethical issues. Methods: The study is cross-sectional and questionnaire-based and involved 616 blood donors from the Gaza Strip. Results: The majority of participants (86%) showed a positive attitude towards donating blood for medical research, including genetic studies. About two-thirds of participants agreed that informed consent should be taken before conducting medical research on the donated blood. A similar percentage also accepted linking of their health information to the donated blood samples. On the other hand, about 38% of participants disapproved of sharing of their data with third parties such as health insurance companies and health authorities. Finally, 10% of participants stated that their future blood donation decision would be affected if they knew that part of their donated blood was to be used in research without taking their permission. Conclusion: Blood donors in Gaza Strip have a positive attitude toward using their donated blood for medical research. More awareness is required with respect to the importance of informed consent and access to biomedical information. PMID- 30288134 TI - Impact of novel antifibrotic therapy on patient outcomes in idiopathic pulmonary fibrosis: patient selection and perspectives. AB - Patients with idiopathic pulmonary fibrosis, an incurable, progressive fibrotic interstitial lung disease, suffer an impaired quality of life due to symptoms, resultant functional limitations, and the constraints of supplemental oxygen. Two antifibrotic medications, nintedanib and pirfenidone, are approved for the treatment of idiopathic pulmonary fibrosis. Both medications slow the rate of decline of lung function, but their effect on patient-reported outcomes is not yet fully understood. Nintedanib may slow the decline in health-related quality of life for treated patients. Pirfenidone may slow the progression of dyspnea and improve cough. Patients and providers should participate in shared decision making when starting antifibrotic therapy, taking into consideration the benefits of treatment in addition to drug-related side effects and dosing schedules. Although antifibrotic therapy may have an impact on health-related quality of life, providers should also focus on comprehensive care of the patient to improve health-related outcomes. This includes a multidisciplinary evaluation, diagnosis and treatment of comorbid medical conditions, and referral to and participation in a pulmonary rehabilitation program. PMID- 30288136 TI - The value of using seasonality and meteorological variables to model intra-urban PM2.5 variation. AB - A yearlong air monitoring campaign was conducted to assess the impact of local temperature, relative humidity, and wind speed on the temporal and spatial variability of PM2.5 in El Paso, Texas. Monitoring was conducted at four sites purposely selected to capture the local traffic variability. Effects of meteorological events on seasonal PM2.5 variability were identified. For instance, in winter low-wind and low-temperature conditions were associated with high PM2.5 events that contributed to elevated seasonal PM2.5 levels. Similarly, in spring, high PM2.5 events were associated with high-wind and low-relative humidity conditions. Correlation coefficients between meteorological variables and PM2.5 fluctuated drastically across seasons. Specifically, it was observed that for most sites correlations between PM2.5 and meteorological variables either changed from positive to negative or dissolved depending on the season. Overall, the results suggest that mixed effects analysis with season and site as fixed factors and meteorological variables as covariates could increase the explanatory value of LUR models for PM2.5. PMID- 30288137 TI - Bilingual education for young children: review of the effects and consequences. AB - Bilingual education has been an educational option in many countries for over 50 years but it remains controversial, especially in terms of its appropriateness for all children. The present review examines research evaluating the outcomes of bilingual education for language and literacy levels, academic achievement, and suitability for children with special challenges. The focus is on early education and the emphasis is on American contexts. Special attention is paid to factors such as socioeconomic status that are often confounded with the outcomes of bilingual education. The conclusion is that there is no evidence for harmful effects of bilingual education and much evidence for net benefits in many domains. PMID- 30288138 TI - Microfluidic generation of transient cell volume exchange for convectively driven intracellular delivery of large macromolecules. AB - Efficient intracellular delivery of target macromolecules remains a major obstacle in cell engineering and other biomedical applications. We discovered a unique cell biophysical phenomenon of transient cell volume exchange by using microfluidics to rapidly and repeatedly compress cells. This behavior consists of brief, mechanically induced cell volume loss followed by rapid volume recovery. We harness this behavior for high-throughput, convective intracellular delivery of large polysaccharides (2000 kDa), particles (100 nm), and plasmids while maintaining high cell viability. Successful proof of concept experiments in transfection and intracellular labeling demonstrated potential to overcome the most prohibitive challenges in intracellular delivery for cell engineering. PMID- 30288139 TI - Lanthanide DO3A-tropone complexes: efficient dual MR/NIR imaging probes in aqueous medium. AB - In this work, we describe a novel DOTA (1,4,7,10-tetraazacyclododecane-1,4,7,10 tetraacetic acid) based ligand with a chromophoric tropone coordinating sidearm (1). Ln3+ complexes of 1 have one inner sphere water molecule. The r1 relaxivity of Gd1 is similar to that of the commercial Gd-based MRI agents. The neutral O donor atom of the tropone moiety slows down the water exchange rate by a factor of 3 compared to GdDOTA. In addition, Nd1 and Yb1 complexes exhibit significant NIR emission in aqueous solutions indicating that the tropone unit is an efficient sensitizer for these Ln3+-ions. Therefore, this new ligand is a promising platform for the design of Ln3+ based dual MR/optical imaging probes. PMID- 30288140 TI - Management Options for Nocturia. PMID- 30288141 TI - Infertility in Patients With Klinefelter Syndrome: Optimal Timing for Sperm and Testicular Tissue Cryopreservation. AB - Male factor infertility is a complex issue presenting many diagnostic and management challenges. It is responsible for about 50% of all causes of infertility and thus carries significant medical, financial, and psychological implications for the couples struggling with conception. Klinefelter syndrome is the most common chromosomal male anomaly associated with male infertility. This review focuses specifically on non-obstructive azoospermia secondary to Klinefelter syndrome and discusses controversies surrounding fertility management in patients with this genetic disorder.

AB - Evidence suggests lower nadir testosterone levels during the first year of androgen deprivation therapy improve advanced prostate cancer clinical outcomes. We evaluated pivotal trials for subcutaneously administered leuprolide acetate (1 , 3-, 4-, and 6-month doses) to determine nadir testosterone levels. Pooled analysis showed 99%, 97%, and 91% of patients reached nadir testosterone <=20, <=10, and <=5 ng/dL respectively (median <=3 ng/dL). Across all available categories, $88% of patients reached nadir testosterone <=5 ng/dL, and <3% experienced a microsurge. Achievement and maintenance of low nadir testosterone levels may improve progression-free survival and time to onset of castrate resistant prostate cancer. PMID- 30288143 TI - Balancing Confounding and Generalizability Using Observational, Real-world Data: 17-gene Genomic Prostate Score Assay Effect on Active Surveillance. AB - Randomized, controlled trials can provide high-quality, unbiased evidence for therapeutic interventions but are not always a practical or viable study design for certain healthcare decisions, such as those involving prognostic or predictive testing. Studies using large, real-world databases may be more appropriate and more generalizable to the intended target population of physicians and patients to answer these questions but carry potential for hidden bias. We illustrate several emerging methods of analyzing observational studies using propensity score matching (PSM) and coarsened exact matching (CEM). These advanced statistical methods are intended to reveal a "hidden experiment" within an observational database, and so refute or confirm a potential causal effect of assignment to an intervention and study outcome. We applied these methods to the OptumTM Research Database (ORD; Eden Prairie, MN) of electronic health records and administrative claims data to assess the effect of the 17-gene Genomic Prostate Score(r) (GPSTM; Genomic Health, Redwood City, CA) assay on use of active surveillance (AS). In a traditional multivariable logistic regression, the GPS assay increased the use of AS by 29% (95% CI, 24%-33%). Upon applying the matching methods, the effect of the GPS assay on AS use varied between 27% and 80% and the matched data were significant among all algorithms. All matching algorithms performed well in identifying matched data that improved the imbalance in baseline covariates. By using different matching methods to assess causal inference in an observational database, we provide further confidence that the effect of the GPS assay on AS use is statistically significant and unlikely to be a result of confounding due to differences in baseline characteristics of the patients or the settings in which they were seen. PMID- 30288144 TI - Prostate Biopsy Characteristics: A Comparison Between the Pre- and Post-2012 United States Preventive Services Task Force (USPSTF) Prostate Cancer Screening Guidelines. AB - To compare prostate cancer (PCa) characteristics diagnosed by prostate biopsy (Pbx) in the 3 years before and after the 2012 United States Preventive Services Task Force (USPSTF) recommendations for PCa screening, we completed a retrospective comparative analysis of 402 sequential PCa patients diagnosed from 2010 to 2012 (3 years) with 552 PCa patients diagnosed from 2015 to 2017 (3 years). Data was collected on patient age, race, total number of biopsies performed, prostate specific antigen (PSA), Gleason sum score (GSS), and digital rectal examination (DRE). The data was analyzed to determine whether the 2012 USPSTF screening recommendations affected PCa characteristics. Two study groups were defined, Group A and Group B, prior to and after the 2012 USPSTF screening recommendations, respectively. In Group A (pre- 2012 USPSTF recommendations), 567 patients/year underwent a Pbx versus Group B, 398 patients/year, a 30% reduction post-USPSTF. The annual positive Pbx rate for Group A is 134/year versus Group B 184/year, a 37.3% increase post-USPSTF. Group A had high-grade PCa (GSS 7-10) in 51.5% versus Group B in 60.1%, an 8.6% increase post-USPSTF. In Group B, the total number of positive biopsies was increased by 100%. This study shows that in Group B, the Pbx rate decreased by 30% but the annual PCa detection rate increased by 37%. High-grade GSS (7-10) PCa increased by 8.6%. Despite a reduction in the total number of prostate biopsies by 30%, there was a 100% increase in the total number of positive prostate biopsies.

AB - The use of botulinum toxin A (BTX-A) has revolutionized the treatment of neurogenic lower urinary tract dysfunction (NLUTD) over the past three decades. Initially, it was used as a sphincteric injection for detrusor sphincter dyssynergia but now is used mostly as intradetrusor injection to treat neurogenic detrusor overactivity (NDO). Its use is supported by high-level-of-evidence studies and it has become the gold-standard treatment for patients with NDO refractory to anticholinergics. Several novelties have emerged in the use of BTX A in neurourology over the past few years. Although onabotulinumtoxinA (BOTOX(r), Allergan, Inc., Irvine, CA) remains the only BTX-A for which use is supported by large, multicenter, randomized, controlled trials (RCT), and is therefore the only one to be licensed in the United States and Europe, a second BTX-A, abobotulinumtoxinA (Dysport(r), Ipsen Biopharmaceuticals, Basking Ridge, NJ), is also supported by high-level-of-evidence studies. Other innovations in the use of BTX-A in neurourology during the past few years include the BTX switch (from abobotulinumtoxinA to onabotulinumtoxinA or the opposite) as a rescue option for primary or secondary failures of intradetrusor BTX-A injection and refinements in intradetrusor injection techniques (number of injection sites, injection into the trigone). There is also a growing interest in long-term failure of BTX-A for NDO and their management, and a possible new indication for urethral sphincter injections.

PMID- 30288152 TI - Covariance nuclear magnetic resonance methods for obtaining protein assignments and novel correlations. AB - Protein NMR resonance assignment can be a tedious and error prone process, and it is often a limiting factor in biomolecular NMR studies. Challenges are exacerbated in larger proteins, disordered proteins, and often alpha-helical proteins, owing to an increase in spectral complexity and frequency degeneracies. Here, several multi-dimensional spectra must be inspected and compared in an iterative manner before resonances can be assigned with confidence. Over the last two decades, covariance NMR has evolved to become applicable to protein multi dimensional spectra. The method, previously used to generate new correlations from spectra of small organic molecules, can now be used to recast assignment procedures as mathematical operations on NMR spectra. These operations result in multidimensional correlation maps combining all information from input spectra and providing direct correlations between moieties that would otherwise be compared indirectly through reporter nuclei. Thus, resonances of sequential residues can be identified and side-chain signals can be assigned by visual inspection of 4D arrays. This review highlights advances in covariance NMR that permitted to generate reliable 4D arrays and describes how these arrays can be obtained from conventional NMR spectra. PMID- 30288153 TI - Image Segmentation, Registration and Characterization in R with SimpleITK. AB - Many types of medical and scientific experiments acquire raw data in the form of images. Various forms of image processing and image analysis are used to transform the raw image data into quantitative measures that are the basis of subsequent statistical analysis. In this article we describe the SimpleITK R package. SimpleITK is a simplified interface to the insight segmentation and registration toolkit (ITK). ITK is an open source C++ toolkit that has been actively developed over the past 18 years and is widely used by the medical image analysis community. SimpleITK provides packages for many interpreter environments, including R. Currently, it includes several hundred classes for image analysis including a wide range of image input and output, filtering operations, and higher level components for segmentation and registration. Using SimpleITK, development of complex combinations of image and statistical analysis procedures is feasible. This article includes several examples of computational image analysis tasks implemented using SimpleITK, including spherical marker localization, multi-modal image registration, segmentation evaluation, and cell image analysis. PMID- 30288154 TI - Cost Implications of Reactive Versus Prospective Testing for Dihydropyrimidine Dehydrogenase Deficiency in Patients With Colorectal Cancer: A Single-Institution Experience. AB - Background: Severe toxicity is experienced by a substantial minority of patients receiving fluoropyrimidine-based chemotherapy, with approximately 20% of these severe toxicities attributable to polymorphisms in the DPYD gene. The DPYD codes for the enzyme dihydropyrimidine dehydrogenase (DPD) important in the metabolism of fluoropyrimidine-based chemotherapy. We questioned whether prospective DPYD mutation analysis in all patients commencing such therapy would prove more cost effective than reactive testing of patients experiencing severe toxicity. Methods: All patients experiencing severe toxicity from fluoropyrimidine-based chemotherapy for colorectal cancer in an Irish private hospital over a 3-year period were tested for 4 DPYD polymorphisms previously associated with toxicity. The costs associated with an index admission for toxicity in DPD-deficient patients were examined. A cost analysis was undertaken comparing the anticipated cost of implementing screening for DPYD mutations versus current usual care. One way sensitivity analysis was conducted on known input variables. An alternative scenario analysis from the perspective of the Irish health-care payer (responsible for public hospitals) was also performed. Results: Of 134 patients commencing first-line fluoropyrimidine chemotherapy over 3 years, 30 (23%) patients developed grade 3/4 toxicity. Of these, 17% revealed heterozygote DPYD mutations. The cost of hospitalization for the DPYD-mutated patients was ?232 061, while prospectively testing all 134 patients would have cost ?23 718. Prospective testing would result in cost savings across all scenarios. Conclusions: The cost of hospital admission for severe chemotherapy-related toxicity is significantly higher than the cost of prospective DPYD testing of each patient commencing fluoropyrimidine chemotherapy. PMID- 30288156 TI - Pharmacokinetic Equivalence of the High Dose Strength Fixed-Dose Combination Tablet of Gemigliptin/Metformin Sustained Release (SR) and Individual Component Gemigliptin and Metformin XR Tablets in Healthy Subjects. AB - Background: In type 2 diabetes mellitus therapy, fixed-dose combination (FDC) can offer not only benefits in glucose control via the combined use of agents, but also increase patient compliance. The aim of this study was to assess the pharmacokinetic equivalence of the high dose of the FDC tablet (gemigliptin/metformin sustained release [SR] 50/1,000 mg) and a corresponding co administered dose of individual tablets. Methods: This study was randomized, open label, single dose, two treatments, two-period, crossover study, which included 24 healthy subjects. Subjects received the FDC or individual tablets of gemigliptin (50 mg) and metformin XR (1,000 mg) in each period. Geometric mean ratios (GMRs) and 90% confidence intervals (CIs) of maximum plasma concentration (Cmax) and area under the plasma concentration-time curve from time zero to the time of the last quantifiable concentration (AUClast) of the FDC tablet and co administration of individual tablet for both gemigliptin and metformin were calculated. Results: The GMRs (FDC tablets/co-administration; 90% CIs) for Cmax and AUClast of gemigliptin were 1.079 (0.986-1.180) and 1.047 (1.014-1.080), respectively. For metformin, the GMRs for Cmax, and AUClast were 1.038 (0.995 1.083) and 1.041 (0.997-1.088), respectively. The 90% CIs for GMRs of Cmax and AUClast for gemigliptin and metformin fell entirely within bounds of 0.800-1.250. Both administration of FDC tablet and co-administration of individual tablets were well tolerated. Conclusion: FDC tablet exhibited pharmacokinetic equivalence and comparable safety and tolerability to co-administration of corresponding doses of gemigliptin and metformin XR as individual tablets.

AB - Purpose: To investigate the use of proton pump inhibitors (PPIs) and the risk of pancreatic cancer. Methods: A nested case-control analysis was conducted. Patients with pancreas cancer were matched with controls by propensity score. Univariate and multivariate logistic regression models were used to determine whether PPIs use affected the risk of pancreas cancer. Dose effect was analyzed based on the cumulative defined daily dose (DDD), which was calculated using the total supply of PPIs to individual patients in terms of days and quantity. Results: A total of 1087 patients with pancreas cancer were matched with 1087 control patients from the database. The overall adjusted odds ratio (OR) of PPI use associated with pancreas cancer was 1.69 (95% confidence interval [CI], 1.44 2.05). Dose analysis by cumulative DDD, based on all types of PPI combined, revealed a lower adjusted OR of 0.92 (95% CI, 0.64-1.33) for those on <30 cumulative DDD compared with those on >=150 cumulative DDD, whose adjusted OR was 2.19 (95% CI, 1.68-2.85). Compared with PPI nonusers, the risks of pancreas cancer were: OR 0.89 (95% CI, 0.62-1.27) for patients using PPI <30 days and 2.22 (95% CI, 1.68-2.94) for >=150 days. Conclusions: Risk of pancreas cancer was associated with PPI use in patients with peptic ulcer diseases or gastroesophageal reflux disease. PMID- 30288157 TI - Characteristics of High-Intent Suicide Attempters Admitted to Emergency Departments. AB - Background: The suicide rate in Korea has been the highest among the Organization for Economic Cooperation and Development countries since 2003. However, there is a lack of in-depth data regarding the characteristics of suicide attempters. Understanding the intent of suicide attempters will help improve the effectiveness of suicide prevention strategies. Therefore, to provide a resource for developing the necessary interventions, this study aimed to examine the differences in suicide-related and clinical variables according to the strength of suicidal intent. Methods: The subjects were 328 suicide attempters admitted to emergency departments at 5 university hospitals in Daegu-Gyeongbuk province between 2011 and 2014. We used various scales to examine suicide-related and clinical variables and a structured questionnaire to explore psychosocial characteristics. We evaluated suicidal intent using the Pierce Suicide Intent Scale and a clinician-rated scale that measured suicidal authenticity. Results: Individuals with high suicidal intent were significantly older, had higher Hamilton Depression Rating Scale (HDRS) scores, higher rates of premeditation, and sustained suicidal ideation. Furthermore, suicide methods, timing, and psychiatric treatment histories differed by the strength of subjects' suicidal intent. Moreover, multiple logistic regression showed that depressed mood as a reason for attempting suicide, premeditation, and higher HDRS scores were significantly associated with higher suicidal intent. Conclusion: Depression, premeditation, older age, and sustained suicidal ideation were characteristics of individuals with high suicidal intent, and it is necessary to evaluate and monitor these factors to prevent repeated suicide attempts. PMID- 30288158 TI - Treatment Outcomes in Children and Adolescents with Relapsed or Progressed Solid Tumors: a 20-year, Single-Center Study. AB - Background: By estimating the survival rates and exploring prognostic factors in pediatric patients with relapsed or progressed solid tumors, our purpose was to generate background data for future studies. Methods: We reviewed the medical records of 258 patients with solid tumors who experienced relapse/progression and received subsequent salvage treatment between 1996 and 2016. Results: A total of 60 patients remained progression-free during first-line salvage treatment, while the remaining 198 patients experienced relapse/progression again; 149 underwent second-line salvage treatment. A total of 76 patients underwent high-dose chemotherapy and autologous stem cell transplantation (HDCT/auto-SCT), and 44 patients received allogeneic SCT. The 10-year progression-free survival (PFS) and overall survival (OS) from relapse/progression were 18.4% +/- 2.7% and 24.5% +/- 3.0%, respectively. Survival rates were relatively higher in patients with anaplastic ependymoma, initially non-high-risk neuroblastoma, osteosarcoma, Wilms tumor and retinoblastoma. A multivariate analysis showed that relapse/progression during initial treatment, metastatic relapse/progression, and impossible debulking surgery were independent poor prognostic factors for both PFS and OS. Patients who exhibited a complete response or partial response during conventional salvage treatment showed significantly higher survival after SCT than those with stable disease or progressive disease (10-year OS: 54.8% +/- 7.0% vs. 7.0% +/- 3.5%, P < 0.001). Conclusion: The prognosis of relapsed/progressed pediatric solid tumors still remains unsatisfactory. New, effective treatment strategies are needed to overcome limitations of current approaches. Hopefully, the background data generated herein will be used in future clinical trials involving patients with relapsed/progressed solid tumors. PMID- 30288159 TI - Factors Related with Utilizing Hospice Palliative Care Unit among Terminal Cancer Patients in Korea between 2010 and 2014: a Single Institution Study. AB - Background: Establishing and designating specialized hospice palliative care units (HPCUs) has been an important part of national policy to promote hospice palliative care in Korea in the recent decade. However, few studies have sought to identify patterns and barriers for utilizing HPCU over the period of national policy implementation. We aimed to investigate factors related with utilizing HPCU for terminal cancer patients after consultation with a palliative care team (PCT). Methods: We reviewed medical records for 1,028 terminal cancer patients who were referred to the PCT of the National Cancer Center in 2010 and 2014. We compared the characteristics of the patients who decided to utilize HPCU and those who did not. We also analyzed factors influencing choices for a medical institution and reasons for not selecting an HPCU. Results: The patients' mean age was 61.0 +/- 12.2, with lung cancer patients (24.3%) comprising the largest percentage of these patients. The percentage of referred patients who utilized an HPCU was 53.9% in 2014, increasing from 44.6% in 2010. Older age and awareness of terminal illness were found to be positively associated with utilization of an HPCU. The most common reason for not selecting an HPCU was "refusing hospice facility" (34.9%), followed by "near death," "poor accessibility to an HPCU," and "caregiving problems." Conclusion: Compared to 2010, HPCU utilization by terminal cancer patients increased in 2014. Improving awareness of terminal condition among patients and family members and earlier discussion of end-of-life care would be important to promote utilization of HPCU.

PMID- 30288162 TI - Constraining chemical transport PM2.5 modeling outputs using surface monitor measurements and satellite retrievals: application over the San Joaquin Valley. AB - Advances in satellite retrieval of aerosol type can improve the accuracy of near surface air quality characterization by providing broad regional context and decreasing metric uncertainties and errors. The frequent, spatially extensive and radiometrically consistent instantaneous constraints can be especially useful in areas away from ground monitors and progressively downwind of emission sources. We present a physical approach to constraining regional-scale estimates of PM2.5, its major chemical component species estimates, and related uncertainty estimates of chemical transport model (CTM; e.g., the Community Multi-scale Air Quality Model) outputs. This approach uses ground-based monitors where available, combined with aerosol optical depth and qualitative constraints on aerosol size, shape, and light-absorption properties from the Multi-angle Imaging SpectroRadiometer (MISR) on the NASA Earth Observing System's Terra satellite. The CTM complements these data by providing complete spatial and temporal coverage. Unlike widely used approaches that train statistical regression models, the technique developed here leverages CTM physical constraints such as the conservation of aerosol mass and meteorological consistency, independent of observations. The CTM also aids in identifying relationships between observed species concentrations and emission sources. Aerosol air mass types over populated regions of central California are characterized using satellite data acquired during the 2013 San Joaquin field deployment of the NASA Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality (DISCOVER-AQ) project. We investigate the optimal application of incorporating 275 m horizontal-resolution aerosol air-mass type maps and total-column aerosol optical depth from the MISR Research Aerosol retrieval algorithm (RA) into regional-scale CTM output. The impact on surface PM2.5 fields progressively downwind of large single sources is evaluated using contemporaneous surface observations. Spatiotemporal R 2 and RMSE values for the model, constrained by both satellite and surface monitor measurements based on 10 fold cross-validation, are 0.79 and 0.33 for PM2.5, 0.88 and 0.65 for NO3 -, 0.78 and 0.23 for SO4 2-, and 1.01 for NH+, 0.73 and 0.23 for OC, and 0.31 and 0.65 for EC, respectively. Regional cross-validation temporal and spatiotemporal R2 results for the satellite-based PM2.5 improve by 30 % and 13 %, respectively, in comparison to unconstrained CTM simulations and provide finer spatial resolution. SO4 2- cross-validation values showed the largest spatial and spatiotemporal R2 improvement, with a 43 % increase. Assessing this physical technique in a well- instrumented region opens the possibility of applying it globally, especially over areas where surface air quality measurements are scarce or entirely absent. PMID- 30288163 TI - Anti-Mullerian Hormone Levels in Preeclampsia: A Systematic Review of the Literature. AB - Objective: Serum Anti-Mullerian hormone (AMH) has been implicated in the pathogenesis of cardiovascular disease. Its prognostic value in determining the risk of developing preeclampsia remains, to date, unclear. The purpose of the present systematic review is to accumulate current evidence in this field. Materials and methods: We searched Medline (1966-2017), Scopus (2004-2017), Clinicaltrials.gov (2008-2017), EMBASE (1980-2017), LILACS (1986-2017) and Cochrane Central Register of Controlled Trials CENTRAL (1999-2017) databases. Results: Four studies were included in with a total number of 401 women. Among them 146 had preeclampsia while 232 were recruited as normotensive controls. Current data are suggestive of the potential predictive value of serum AMH as its levels seem to be lower among women that develop preeclampsia. One study reported that women with and AMH value below the 10th percentile of the studied population had a 3.3 increased risk of developing preeclampsia (OR 3.3, 95% CI 1.2-8.7, p = 0.01). Conclusion: Taking in mind these findings, future studies are needed in this field to establish optimal cut-off values and evaluate the specificity and sensitivity of this biomarker during the first trimester of pregnancy. PMID- 30288164 TI - The Effect of Auriculotherapy on Labor Pain, Length of Active Phase and Episiotomy Rate Among Reproductive Aged Women. AB - Objective: This study aimed to evaluate the effect of auriculotherapy on labor pain, the length of the active phase, and episiotomy rate among reproductive aged Iranian women. Materials and methods: In this study, 80 women were assigned to two groups: auriculotherapy (n = 40) and control group (n = 40). Auriculotherapy was performed in the earlobe in the Zero, Shen Men, Uterus, Pelvic, Abdomen, Spleen, External genitalia, and Master cerebral regions in the cervix dilation of 4, 6, and 8 cm between uterine contractions. The control group received routine hospital care. The labor pain, duration of the active phase, and rate of episiotomy were assessed in two groups. The independent t- test and chi-square were used for statistical purposes. Results: The mean of labor pain during the active phase was 7.56 +/- 0.83 in the auriculotherapy group and 8.43 +/- 0.69 in the control group (p < 0.001). The length of active phase was significantly lower in the auriculotherapy than that in the control group (176.2 +/- 1 min vs. 342.8+/-87.2 min, p < 0.001). The rate of normal vaginal delivery (without an episiotomy or perineal tears) was significantly higher in the auriculotherapy group than that in the control group (50% vs. 2.5%, p < 0.001). Conclusion: Auriculotherapy is safe, cost effective and devoid of side effects to reduce the labour pain, length of the active phase and the rate of episiotomy in nulliparous women. This method can be considered as a complementary medicine in labour. PMID- 30288166 TI - Evaluation of Feeding Disorders Including Gastro-Esophageal Reflux and Oropharyngeal Dysfunction in Children With Cerebral Palsy. AB - Objective: This cross sectional study aims to survey developing feeding disorders and nutritional deficiencies disorders in children with neurodevelopmental disorders such as cerebral palsy. Materials and methods: A total of 50 children (28 boys and 22 girls) with cerebral palsy and symptoms suggesting gastrointestinal problems such as choking, recurrent pneumonia and poor weight gain, who referred to the Pediatric department of Vali-asr Hospital, Imam Khomeini hospital complex between 1 October 2012 and 30 October 2013, were checked. Motor function classification system was used to classify patient's functional gross motor severity. All patients were examined and underwent deglutition videofluroscopy (modified barium swallow) and upper GI endoscopy with esophageal biopsies. Outcome of this study was the prevalence of oropharyngeal incoordination and GERD. Its relationship with some variables like motor and cognitive developmental delay were analyzed and p value < 0.05 was considered significant. Medical therapy and/or oral physiotherapy and nutritional rehabilitation were started. They were examined after 6 months of treatment. Decrease in choking and episodes of respiratory infections that needed hospitalization and weight gain after 6 months treatment were considered as secondary outcomes (response to treatment). Results: Prevalence of GERD was 66% and oropharyngeal dysphagia was estimated 82%. According to results of video fluroscopy and endoscopic biopsies, 52% of patients were affected by both GERD and oropharyngeal dysfunction. The gross motor function disability was the only variable that significantly related to the prevalence of feeding disorders (p = 0.015). Despite nutritional rehabilitation only 46% of children have weight gain. Conclusion: Feeding disorders such as GERD and oropharyngeal dysfunction are more prevalent in children with cerebral palsy especially in children with severe gross motor disabilities. Since, clinical manifestations of these disorders can be similar accurate diagnostic methods should be selected for all children with cerebral palsy and gastrointestinal symptoms. Treatment should start early to reduce the complications and improve outcomes. PMID- 30288165 TI - Association of Hypothyroidism and Anti-Thyroid Antibodies With Preterm Delivery: A Cross Sectional Study. AB - Objective: Preterm delivery is a common and eventful phenomenon with long standing complications, heavily burdening the health system. Many risk factors have been suggested to increase the likelihood of this event, one being hypothyroidism and high levels of anti-thyroid antibodies. The present study sought to explore the association between hypothyroidism and anti-thyroid antibodies with preterm delivery. Materials and methods: A case control study was conducted on 400 patients attending Educational-Medical centers of Urmia University of Medical Sciences (Urmia, Iran) between November 2013 and April 2016, in which 200 patients with term deliveries and 200 patients with preterm deliveries were compared for differences in hypothyroidism, existence of anti- thyroperoxidase (TPO) antibodies based on blood samples obtained from the patients which were tested using chemi-luminescence method. Results: In the group of patients with preterm delivery, 85 patients had hypothyroidism (42.5%), and from the term delivery group, 67 patients (33.5%) had hypothyroidism, the difference was not statistically significant (p = 0.14). But, when groups of early and late preterm deliveries were compared in terms of having anti-TPO antibodies, there was a significant difference between them, with early preterm delivery having 8 patients positive out of 44 patients and late preterm delivery having 7 positives out of 141 patients (p = 0.004). Conclusion: Hypothyroidism had an insignificant effect on preterm delivery rates, but the existence of anti TPO antibodies in the serum had a significant increasing effect on early preterm deliveries and could be regarded as a risk factor. PMID- 30288167 TI - Perceived Stigma in People Living With HIV in Qom. AB - Objective: This study aimed to report on perceived stigma by PLWH and factors that affect it. Materials and methods: A cross-sectional study was carried out on 120 PLWH in Qom, Iran from November 2015 to April 2016. Persian version of Fife and Wright's scale was used to measure perceived stigma. Results: The mean score of stigma was 73.19 +/- 12.23 (range: 48-97). The means of external stigma and internal stigma were 43.70 +/- 8.61 (range: 19-60), and 29.49 +/- 5.32 (range: 17 40), respectively. Living in a rural areas (beta = 10.341, p = 0.006), unemployment status (beta = 6.910, p = 0.006), and poor support from family members (beta = 4.772, p = 0.028) significantly increased the level of perceived stigma. PLWH experience a considerable level of stigma in their daily life. Mass media involvement to increase public awareness and reduce HIV related stigma need be more highlighted. Conclusion: Working with the patients' families, interventions in the rural areas and workplaces, and providing social supports is necessary to minimize the HIV related stigma. PMID- 30288168 TI - Pregnant Women's Health Literacy in the South of Iran. AB - Objective: Investigate the health literacy of pregnant women in the south of Iran. Materials and methods: The present descriptive-analytical study was conducted on 775 pregnant women in the south of Iran (including Boushehr, Ahvaz, Zahedan and Bandar Abbas cities) through the clustering sample selection method. The data were collected through the Test of Functional Health Literacy in Adults: TOFHLA, and were analyzed statistically via SPSS 16 through independent-sample t test and ANOVA. Results: The average age of the subjects was 31.89 +/- 7.54 years. The results indicated that 15.5% of the subjects had an inadequate level of health literacy; 41.7% had a border-line level of health literacy, and 42.8% had an adequate level of literacy. Significant correlations were found between each of these variables and the subjects' level of health literacy: education, age, occupation and care provision during pregnancy (p ? 0.05). The highest mean score of health literacy belonged to Ahvaz while the lowest belonged to Boushehr. Conclusion: According to the results, the health literacy level of pregnant women in the target geographical areas showed to be inadequate or on a border-line. Moreover, subjects' education, age and occupation showed to be significantly correlated with health literacy. Therefore, promoting pregnant women's health literacy through simplifying health-related information, use of audio-visual media, improving communicative skills among the health staff and mothers can be effective.

AB - Objective: To evaluate the relationship between maternal serum levels of pregnancy-associated-plasma-protein-A (PAPP-A) and beta-human-chorionic gonadotropin (beta-hCG) and pregnancy complications. Materials and methods: This is a case-control study conducted during 2015- 2016. Women at their first pregnancy were enrolled and serum PAPP-A and free-beta-hCG were measured in 9-14 weeks of gestation. They were followed till the end of pregnancylooking for complications including preterm labor, pregnancy induced hypertension (PIH), abortion, and intra-uterine growth retardation (IUGR). Results: A total of 1070 pregnant women (mean age: 28.64 +/- 4.95 years) were enrolled. Low serum levels of PAPP-A were more frequent in patients developing IUGR (17.4% versus 1.2%, p < 0.001), preterm labor (13% versus 2%, p = 0.013), and PIH (17.4% versus 4%, p = 0.015) compared those without complications. The serum levels of free-beta-hCG were not different in patients with and without complications (p > 0.05). Conclusion: There is an association between low serum levels of PAPP-A and developing IUGR, preterm labor, and PIH. PMID- 30288170 TI - Successful Pregnancy Outcome in Recurrent Ovarian Cancer in a 26 Year Old: A Case Report. AB - Objective: To report a case of Successful Pregnancy Outcome in Recurrent Ovarian Cancer in a 26 year Old. Case Report: A 26 years old primigravida presented in antenatal clinic at 23 weeks of pregnancy with recurrence of ovarian cancer of mucinous type. Following refusal of surgical management, two courses of single dose carboplatin was administered. However, before third cycle of chemotherapy could be administered ,there was deranged liver functions tests, following which elective Cesarean section with staging laparotomy was planned at 34 weeks for breech presentation with oligohydramnios. A live healthy baby girl 2.3kg was delivered. Total abdominal hysterectomy with right salpingo-oopherectomy, infracolic omentectomy, appendectomy was done. The final diagnosis was recurrent mucinous ovarian adenocarcinoma. Postoperatively, she was given six cycles of chemotherapy (carboplatin and paclitaxel). Conclusion: Chemotherapy and surgery, both are safe beyond first trimester and multidisciplinary treatment must be planned after taking into account the wishes of couple. PMID- 30288171 TI - The Association Between Dental Anxiety And Psychiatric Disorders And Symptoms: A Systematic Review. AB - Background: A growing amount of evidence suggests that dental anxiety is associated with other psychiatric disorders and symptoms. A systematic review was conducted to critically evaluate the studies of comorbidity of dental anxiety with other specific phobias and other Axis I psychiatric disorders. Objective: The aim of the review was to explore how dental anxiety is associated with other psychiatric disorders and to estimate the level of comorbid symptoms in dental anxiety patients. Methods: The review was conducted and reported in accordance with the MOOSE statement. Data sources included PubMed, PsycInfo, Web of Science and Scopus. Results: The search produced 631 hits, of which 16 unique records fulfilled the inclusion criteria. The number of eligible papers was low. Study populations were heterogeneous including 6,486 participants, and a total of 25 tests and in few cases clinical interviews were used in the evaluation processes. The results enhanced the idea about the comorbidity between dental anxiety and other psychiatric disorders. The effect was found strong in several studies. Conclusion: Patients with a high level of dental anxiety are more prone to have a high level of comorbid phobias, depression, mood disorders and other psychiatric disorders and symptoms. PMID- 30288173 TI - Genomic and phenotypic characterization of a refactored xylose-utilizing Saccharomyces cerevisiae strain for lignocellulosic biofuel production. AB - Background: Engineered strains of Saccharomyces cerevisiae have significantly improved the prospects of biorefinery by improving the bioconversion yields in lignocellulosic bioethanol production and expanding the product profiles to include advanced biofuels and chemicals. However, the lignocellulosic biorefinery concept has not been fully applied using engineered strains in which either xylose utilization or advanced biofuel/chemical production pathways have been upgraded separately. Specifically, high-performance xylose-fermenting strains have rarely been employed as advanced biofuel and chemical production platforms and require further engineering to expand their product profiles. Results: In this study, we refactored a high-performance xylose-fermenting S. cerevisiae that could potentially serve as a platform strain for advanced biofuels and biochemical production. Through combinatorial CRISPR-Cas9-mediated rational and evolutionary engineering, we obtained a newly refactored isomerase-based xylose fermenting strain, XUSE, that demonstrated efficient conversion of xylose into ethanol with a high yield of 0.43 g/g. In addition, XUSE exhibited the simultaneous fermentation of glucose and xylose with negligible glucose inhibition, indicating the potential of this isomerase-based xylose-utilizing strain for lignocellulosic biorefinery. The genomic and transcriptomic analysis of XUSE revealed beneficial mutations and changes in gene expression that are responsible for the enhanced xylose fermentation performance of XUSE. Conclusions: In this study, we developed a high-performance xylose-fermenting S. cerevisiae strain, XUSE, with high ethanol yield and negligible glucose inhibition. Understanding the genomic and transcriptomic characteristics of XUSE revealed isomerase-based engineering strategies for improved xylose fermentation in S. cerevisiae. With high xylose fermentation performance and room for further engineering, XUSE could serve as a promising platform strain for lignocellulosic biorefinery. PMID- 30288172 TI - Association between chronological depressive changes and physical symptoms in postoperative pancreatic cancer patients. AB - Background: Pancreatic cancer (PC) has poorer prognosis and higher surgical invasiveness than many other cancers, with associated psychiatric symptoms including depression and anxiety. Perioperative depression has not been investigated in PC patients regarding surgical stress and relevant interventions. Methods: We evaluated chronological depressive changes and subjective physical symptoms in surgically treated PC patients preoperatively and at 3 and 6 months postoperatively.Enrolled patients undergoing pancreatic tumor surgery completed questionnaires based on the Self-Rating Depression Scale (SDS) and Functional Assessment of Cancer Therapy for Patients with Hepatobiliary Cancer (FACT-Hep) preoperatively, and at 3 and 6 months postoperatively. Responses were analyzed with JMP(r) Pro using one-way and two-way ANOVA, Spearman's rank correlation coefficient, and multiple regression analysis. Results: Malignancy was diagnosed in 73 of 101 patients postoperatively; SDS score was significantly higher in these patients than in those with benign tumors at all timepoints: malignant/benign, 41.8/37.9 preoperatively (p = 0.004); 43.5/37.8 3 months postoperatively (p = 0.006); and 42.9/37.7 6 months postoperatively (p = 0.020). SDS scores were significantly higher in patients < 65 years old with malignancy at 3 months than at 6 months postoperatively (44.6/42.5, p = 0.046) and in patients with malignancy who underwent pancreaticoduodenectomy at 3 months postoperatively than preoperatively (43.4/41.1; p = 0.028). SDS scores moderately correlated with 8 physical symptom-related FACT-Hep items 3 months postoperatively (p < 0.05), showing low-to-moderate correlation with 16 physical symptom-related FACT-Hep items at 6 months postoperatively (p < 0.05). Multiple regression analysis of FACT-Hep symptoms significantly correlated with SDS scores revealed the following significant variables: "lack of energy" (p < 0.000) and "pain" (p = 0.018) preoperatively (R2 = 0.43); "able to perform usual activities" (p = 0.031) and "lack of energy" (p < 0.000) at 3 months postoperatively (R2 = 0.51); and "stomach swelling or cramps" (p = 0.034) and "bowel control" (p = 0.049) at 6 months postoperatively (R2 = 0.52). Conclusions: PC patients experience persistently high levels of depression preoperatively through 6 months postoperatively, with associated subjective symptoms including pain and gastrointestinal symptoms.

PMID- 30288174 TI - Lignin-carbohydrate complexes: properties, applications, analyses, and methods of extraction: a review. AB - The complexity of lignin and hemicellulose segmentation has been known since the middle of the ninetieth century. Studies confirmed that all lignin units in coniferous species and 47-66% of lignin moieties in deciduous species are bound to hemicelluloses or cellulose molecules in lignin-carbohydrate complexes (LCC). Different types and proportions of lignin and polysaccharides present in biomass lead to the formation of LCC with a great variety of compositions and structures. The nature and amount of LCC linkages and lignin substructures affect the efficiency of pulping, hydrolysis, and digestibility of biomass. This review paper discusses the structures, compositions, and properties of LCC present in biomass and in the products obtained via pretreating biomass. Methods for extracting, fractionating, and analyzing LCC of biomass, pulp, and spent pulping liquors are critically reviewed. The main perspectives and challenges associated with these technologies are extensively discussed. LCC could be extracted from biomass following varied methods, among which dimethyl sulfoxide or dioxane (Bjorkman's) and acetic acid (LCC-AcOH) processes are the most widely applied. The oxidation and methylation treatments of LCC materials elucidate the locations and frequency of binding sites of hemicelluloses to lignin. The two-dimensional nuclear magnetic resonance analysis allows the identification of the structure and the quantity of lignin-carbohydrate bonds involved in LCC. LCC application seems promising in medicine due to its high anti-HIV, anti-herpes, and anti microbial activity. In addition, LCC was successfully employed as a precursor for the preparation of spherical biocarriers. PMID- 30288176 TI - Microbial temperature sensitivity and biomass change explain soil carbon loss with warming. AB - Soil microorganisms control carbon losses from soils to the atmosphere1-3, yet their responses to climate warming are often short-lived and unpredictable4-7. Two mechanisms, microbial acclimation and substrate depletion, have been proposed to explain temporary warming effects on soil microbial activity8-10. However, empirical support for either mechanism is unconvincing. Here we used geothermal temperature gradients (> 50 years of field warming)11 and a short-term experiment to show that microbial activity (gross rates of growth, turnover, respiration and carbon uptake) is intrinsically temperature sensitive and does not acclimate to warming (+ 6 oC) over weeks or decades. Permanently accelerated microbial activity caused carbon loss from soil. However, soil carbon loss was temporary because substrate depletion reduced microbial biomass and constrained the influence of microbes over the ecosystem. A microbial biogeochemical model12-14 showed that these observations are reproducible through a modest, but permanent, acceleration in microbial physiology. These findings reveal a mechanism by which intrinsic microbial temperature sensitivity and substrate depletion together dictate warming effects on soil carbon loss via their control over microbial biomass. We thus provide a framework for interpreting the links between temperature, microbial activity and soil carbon loss on timescales relevant to Earth's climate system. PMID- 30288175 TI - Neck circumference and its association with cardiometabolic risk factors: a systematic review and meta-analysis. AB - Background: Recently, neck circumference (NC) has been used to predict the risk of cardiometabolic factors. This study aimed to perform a systematic review and meta-analysis to examine: (i) the sensitivity (SE) and specificity (SP) of NC to predict cardiometabolic risk factors and (ii) the association between NC and the risk of cardiometabolic parameters. Methods: A systematic search was conducted through PubMed/Medline, Institute of Scientific Information, and Scopus, until 2017 based on the search terms of metabolic syndrome (MetS) and cardio metabolic risk factors. Random-effect model was used to perform a meta-analysis and estimate the pooled SE, SP and correlation coefficient (CC). Results: A total of 41 full texts were selected for systematic review. The pooled SE of greater NC to predict MetS was 65% (95% CI 58, 72) and 77% (95% CI 55, 99) in adult and children, respectively. Additionally, the pooled SP was 66% (95% CI 60, 72) and 66% (95% CI 48, 84) in adult and children, respectively. According to the results of meta-analysis in adults, NC had a positive and significant correlation with fasting blood sugar (FBS) (CC: 0.16, 95% CI 0.13, 0.20), HOMA-IR (0.38, 95% CI 0.25, 0.50), total cholesterol (TC) (0.07 95% CI 0.02, 0.12), triglyceride (TG) concentrations (0.23, 95% CI 0.19, 0.28) and low density lipoprotein cholesterol (LDL-C) (0.14, 95% CI 0.07, 0.22). Among children, NC was positively associated with FBS (CC: 0.12, 95% CI 0.07, 0.16), TG (CC: 0.21, 95% CI 0.17, 0.25), and TC concentrations (CC: 0.07, 95% CI 0.02, 0.12). However, it was not significant for LDL-C. Conclusion: NC has a good predictive value to identify some cardiometabolic risk factors. There was a positive association between high NC and most cardiometabolic risk factors. However due to high heterogeneity, findings should be declared with caution. PMID- 30288177 TI - Effect of spatial heterogeneity and colocalization of eNOS and capacitative calcium entry channels on shear stress-induced NO production by endothelial cells: A modeling approach. AB - Introduction: Colocalization of endothelial nitric oxide synthase (eNOS) and capacitative Ca2+ entry (CCE) channels in microdomains such as cavaeolae in endothelial cells (ECs) has been shown to significantly affect intracellular Ca2+ dynamics and NO production, but the effect has not been well quantified. Methods: We developed a two-dimensional continuum model of an EC integrating shear stress mediated ATP production, intracellular Ca2+ mobilization, and eNOS activation to investigate the effects of spatial colocalization of plasma membrane eNOS and CCE channels on Ca2+ dynamics and NO production in response to flow-induced shear stress. Our model examines the hypothesis that subcellular colocalization of cellular components can be critical for optimal coupling of NO production to blood flow. Results: Our simulations predict that heterogeneity of CCE can result in formation of microdomains with significantly higher Ca2+ compared to the average cytosolic Ca2+. Ca2+ buffers with lower or no mobility further enhanced Ca2+ gradients relative to mobile buffers. Colocalization of eNOS to CCE channels significantly increased NO production. Conclusions: Our results provide quantitative understanding for the role of spatial heterogeneity and the compartmentalization of signals in regulation of shear stress-induced NO production. PMID- 30288178 TI - Co-Administration of Fish Oil With Signal Transduction Inhibitors Has Anti Migration Effects in Breast Cancer Cell Lines, in vitro. AB - Background: There is an urgent need for new therapies to treat cancer metastasis. Fish oil, with high omega 3 fatty acid content, has shown anticancer activity and signal transduction inhibitors have shown anti-metastatic properties. Objective: To provide preliminary in vitro data on the anti-migration potential of signal transduction inhibitors and co-administered fish oil. Methods: MCF-7, TamR and FasR breast cancer cell lines were used to determine the effects of combinations of PD98059, LY294002 and fish oil in growth assays. Modulations of p-Src and COX 2, both mediators of motility and invasion, were then determined by Western blotting and IHC to ascertain effects on migration potential. Results: Migration rates for the three cell lines examined were ranked: FasR>TamR>MCF-7 (p <0.05). Addition of fish oil reduced the number of TamR cells migrating after 48h (p <0.05), while the addition of PD98059 and LY294002 also decreased migratory potential of TamR cells (p <0.05). Addition of PD98059 and LY294002 to TamR cells did not result in a significant decrease in p-Src levels; as was the case when PD98059, LY294002 and 4-hydroxytamoxifen were added to MCF-7 cells. However, the co-administration of fish oil markedly reduced p-Src and COX-2 expression in both cell lines. Conclusion: Co-administration of a commercial fish oil with signal transduction inhibitors results in decreased cell migration via an unknown co operative mechanism and could constitute a novel approach for the treatment of breast cancer metastasis.

AB - Introduction: Tinuvin 770 [bis(2,2,6,6-tetramethyl-4-piperidinyl) sebacate, Ciba Geigy, Basel, Switzerland] is a UV light stabilizer that is a component of many plastic materials used world-wide in the medical and food industries. We report on the acute hemodynamic effects of Tinuvin 770 examined in dogs. Materials and Methods: Tinuvin 770 was dissolved in a mixture of saline and ethanol (1:1 v/v) and was administered to 12 intravenously narcotized and respirated dogs in increasing doses (T1-T7: 1, 3.3, 6.6, 10, 33.3, 66.6 and 100 mg, respectively). The doses were given as bolus injections over a three minute period, and the effects were recorded for 12 minutes. The vehicle was used as a control. Hemodynamic parameters (heart rate, blood pressure, end-diastolic pressure, dp/dt, cardiac output) and ECG were monitored continously. Results: At doses T1 T4, systolic and diastolic blood pressures, mean pressure and ventricular contractility were significantly decreased without significant changes in cardiac output, heart rate, or PQ interval. At doses T5 and T6, declines in blood pressure and myocardial contractility were observed. At doses T6 and T7, heart rate and PQ interval decreased substantially. Irreversible circulatory failure occured in one dog after administering dose T6 and in 8 dogs following dose T7. Conclusion: Tinuvin 770 induces acute hemodynamic alterations. In lower doses, it causes peripheral vasodilatation, however at higher doses acute cardiac failure occured. Plastics containing Tinuvin 770 should be used with care in medical practice and the laboratory. PMID- 30288182 TI - Performance of Cone Beam Computed Tomography Systems in Visualizing the Cortical Plate in 3D Image Reconstruction: An In Vitro Study. AB - Introduction: Cortical bone is an important anatomical structure and its thickness needs to be determined prior to many dental procedures to ensure treatment success. Imaging modalities are necessarily used in dentistry for treatment planning and dental procedures. Three-dimensional image reconstruction not only provides visual information but also enables accurate measurement of anatomical structures; thus, it is necessarily required for maxillofacial examination and in case of skeletal problems in this region. Aims: This study aimed to assess the ability of three Cone Beam Computed Tomography (CBCT) systems including Cranex 3D, NewTom 3G and 3D Promax for Three-Dimensional (3D) image reconstruction of the cortical plate with variable thicknesses. Methods: Depending on the cortical bone thickness, samples were evaluated in three groups of <= 0. 5 mm, 0.6 -1 mm and 1.1-1.5 mm cortical bone thickness. The CBCT scans were obtained from each sample using three systems, their respective FOVs, and 3D scans were reconstructed using their software programs. Two observers viewed the images twice with a two-week interval. The ability of each system in the 3D reconstruction of different thicknesses of cortical bone was determined based on its visualization on the scans. The data were analyzed using SPSS and Kappa test. Results: The three systems showed the greatest difference in the 3D reconstruction of cortical bone with < 0.5 mm thickness. Cranex 3D with 4*6 cm2 FOV had the highest and 3D Promax with 8*8 cm2 FOV had the lowest efficacy for 3D reconstruction of cortical bone. Cranex 3D with 4*6 cm2 and 6*8 cm2 FOVs and NewTom 3G with 5*5 cm2 and 8*5 cm2 FOVs showed significantly higher efficacy for 3D reconstruction of cortical bone with 0.6-1mm thickness while 3D Promax followed by NewTom 3G with 8*8 cm2 FOV had the lowest efficacy for this purpose. Conclusion: Most CBCT systems have high efficacy for 3D image reconstruction of cortical bone with thicknesses over 1 mm while they have poor efficacy for image reconstruction of cortical bone with less than 0.5 mm thickness. Thus, for accurate visualization of anatomical structures on CBCT scans, systems with smaller FOVs and consequently smaller voxel size are preferred. PMID- 30288183 TI - Concerns of a Pediatric Dentist in Dental Stem Cells: An Overview. AB - Stem cell biology has become an essential part of regenerative medicine and dentistry. The fact of availability of these stem cells among various dental tissues has doubled the researcher's enthusiasm in the recent years due to fewer ethical constraints and minimally invasive nature. Stem cells from deciduous tooth among the dental stem cells are the ones obtained with least or no trauma. To date, enormous research has been reported on dental stem cells. The purpose of this review is to focus only on certain aspects of dental stem cells that are important to the specialty of pedodontics. Thus, a detailed emphasis is given on stem cells obtained from human deciduous teeth including their harvesting and storage techniques. PMID- 30288181 TI - Clinical Efficacy in Relieving Dentin Hypersensitivity of Nanohydroxyapatite containing Cream: A Randomized Controlled Trial. AB - Objective: The study aimed to investigate the effectiveness of Apadent Pro (Sangi) Nanohydroxyapatite (nHAP) dental cream to relieve Dentin Hypersensitivity (DHS), compared with a positive control cream containing 20% pure silica (Silica). Methods: In this double-blind, randomized, parallel-group clinical trial, patients diagnosed with DHS and qualified to participate were randomized into two groups, nHAP (n=25) and Silica (n=26). Subjects' baseline and posttreatment sensitivity were assessed using two pain scales, a four-point Dental Pain Scale (DPS) followed by a linear Visual Analog Scale (VAS), after the application of ice-cold and air stimuli. Subjects used custom-fabricated trays to apply their respective cream for 5 minutes once daily following brushing with standard fluoride toothpaste. Posttreatment sensitivity (efficacy) was assessed every 2 weeks for 8 weeks. Mean treatment outcomes (percentage change from baseline) at each time point were compared using the Tukey HSD test for multiplicity (P<0.05). Results: With either air or cold stimulus, VAS and DPS indicated a significant (P<0.001) reduction in DHS at each time point with either nHAP or Silica. Comparing pain scales, VAS showed no significant difference in DHS reduction between the products with either air or cold. However, with DPS, DHS reduction was significantly (P<0.05) better with Silica than with nHAP at all time points with cold, and at 2, 4, and 8 weeks with air. Conclusion: Both Apadent Pro nHAP and Silica dental creams are effective at promoting the relief of DHS symptoms. When comparing the efficacy of the two compounds to relieve DHS, results of the two pain scales were conflicting. PMID- 30288184 TI - Non-Antimicrobial Drugs: Etodolac as a Possible Antimicrobial or Adjuvant Agent Against ESKAPE Pathogens. AB - Introduction: Multiple-drug resistant bacteria are emerging exponentially in healthcare units, threatening public health and requiring novel therapeutic approaches. In 2017, World Health Organization published a list that frames antimicrobial resistant bacteria into priority levels for research of novel drugs to fight them. Methods & Materials: Antimicrobial resistant ESKAPE (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter sp.) and Enterococcus faecalis and Escherichia coli pathogens are present in this list. Representative isolates of each species were used to test the Antibacterial and anti-biofilm formation activities of Etodolac (a Non-Steroidal Anti-Inflammatory Drug, NSAID) at 10 and 1 mM using a broth microdilution technique. Results & Discussion: Statistically significant (p< 0,05) results were observed against all tested gram-positives, particularly anti-biofilm activity against E. faecium. Etodolac had an almost null influence on tested gram-negatives, with the exception of one A. baumannii clinical isolate regarding biofilm formation inhibition. Observed differences deserve further analysis and prospection of the involved mechanisms, to unravel possible novel bacterial targets for drug development. Similar work with other NSAID's may also be worth exploring to ascertain novel therapeutic applications for these drugs, particularly regarding biofilm formation inhibition, per si or as adjuvants of current antibiotherapy, mainly against gram-positives, as suggested by present work. Conclusion: Already approved drugs in terms of pharmacokinetics and safety may deploy faster solutions for antimicrobial therapy against priority pathogens. Current work intends to bring attention to that possibility, particularly regarding NSAIDs, anti-biofilm formation and top priority pathogens. PMID- 30288185 TI - Cadmium Removal from Aqueous Solutions by Strain of Pantoea agglomerans UCP1320 Isolated from Laundry Effluent. AB - Background: Cadmium (Cd), which is a deadly heavy metal of work-related and environmental concern, has been recognized as a substance that is teratogenic and carcinogenic for humans. Therefore, the need to develop low-cost adsorbents to remove heavy metals from aqueous solution has greatly increased. Adsorbents such as Pantoea agglomerans biomass have been used. Aims: We investigated the biotechnological potential of Pantoea agglomerans for the biosorption of cadmium from aqueous solution. Patients and Methods: Pantoea agglomerans UCP1320 isolated from the effluent of a laundry industry was used to remove cadmium from aqueous solutions. Two approaches were compared using active or thermally inactivated biomass. Three different cadmium concentrations of 1, 10 and 100 ppm were used under constant stirring at temperatures of 25 degrees C and 35 degrees C as was pH of 3.0, 5.0 and 7.0. Variable incubation times of 1, 6, and 24h were also studied. Results: The results showed that the temperature did not influence the uptake of metal by living cells nor by inactive bacterial biomass. However, increasing the pH had a positive effect on removing intermediate concentrations of cadmium. Low concentrations of cadmium were completely removed by both live and inactive biomass. Conclusion: Pantoea agglomerans biomass was shown to have a promising performance for the biotechnological removal of cadmium which had been dissolved in aqueous solution.

PMID- 30288186 TI - Composition of Intestinal Microbiota in Two Lines of Rainbow Trout (Oncorhynchus Mykiss) Divergently Selected for Muscle Fat Content. AB - Background: Recently, studies suggest that gut microbiota contributes to the development of obesity in mammals. In rainbow trout, little is known about the role of intestinal microbiota in host physiology. Objective: The aim of this study was to investigate the link between intestinal microbiota and adiposity, by high-throughput 16S RNA gene based illumina Miseq sequencing in two rainbow trout lines divergently selected for muscle lipid content. Fish from these two lines of rainbow trout are known to have a differing lipid metabolism. Methods: Samples from the two lines (L for lean and F for fat) were collected from Midgut (M) and Hindgut (H) in juvenile fish (18 months) to compare intestinal microbiota diversity. Results: Whatever the lines and intestinal localisation, Proteobacteria, Firmicutes and Actinobacteria are the dominant phyla in the bacterial community of rainbow trout (at least 97%). The results indicate that richness and diversity indexes as well as bacterial composition are comparable between all groups even though 6 specific OTUs were identified in the intestinal microbiota of fish from the fat line and 2 OTUs were specific to the microbiota of fish from the lean line. Our work contributes to a better understanding in microbial diversity in intestinal microbiota of rainbow trout. Conclusion: Altogether, our study indicates that no major modification of the intestinal microbiota is induced by selection for muscle lipid content and associated metabolic changes. Finally, we identified members of core microbiota in rainbow trout. PMID- 30288189 TI - Intramuscular Myxoma in the Supinator Muscle with Transient Postoperative Posterior Interosseous Nerve Palsy: A Case Report. AB - Background: Intramuscular myxomas are rare, benign mesenchymal tumors in the musculoskeletal system, and usually, the tumors arise in the large muscles of the thigh, buttocks, shoulder, and upper arm. However, a tumor of the forearm is very rare. Herein, we describe the case of an intramuscular myxoma in the supinator muscle of a 56-year-old female patient. Case Presentation: Magnetic resonance imaging showed a well-defined mass that was hypointense with the peritumoral fat ring sign. The differential diagnoses might have been myxoma, schwannoma, or intramuscular hemangioma. The histopathological image showed abundant myxoid tissue, hypocellularity, and poor vascularization. The cells of the tumor were spindle and stellate-shaped with normochromic nuclei. Based on these findings, the pathological diagnosis was an intramuscular myxoma. After excising the tumor, the patient had transient posterior interosseous nerve palsy. Conclusion: This tumor is curative by resection in toto; however, when the tumor exists in the forearm, surgeons should be careful to avoid damaging surrounding tissues because the tumor is very hard and relatively large compared to the forearm. PMID- 30288190 TI - A Protocol for the Management of the Inpatient Fracture Neck of Femur is Required. AB - Falls within a hospital environment are a major cause of morbidity and may even lead to mortality. Pathways for patients suffering a Fractured Neck of Femur (FNOF) in the community are well established following the development of the Blue Book, BOAST guidelines and National Hip Fracture Database (NHFD). However, there is no such agreed pathway for patients suffering FNOF within a hospital environment. Such patients have been demonstrated to have a higher risk of delays in medical optimisation, delays in operative management, and mortality. There is, therefore, a need to create a nationally agreed guideline for the care of the "inpatient FNOF" as this is an important subgroup of patients. This article highlights this issue as well as advising medical staff on how to identify a potential FNOF within a hospital environment in order to ensure prompt management of a vulnerable group of patients. PMID- 30288187 TI - Losartan, but not Enalapril and Valsartan, Inhibits the Expression of IFN-gamma, IL-6, IL-17F and IL-22 in PBMCs from Rheumatoid Arthritis Patients. AB - Background: Rheumatoid Arthritis (RA) is a chronic and inflammatory disease that affects about 1% of the world's population. Almost 70% of RA patients have a cardiovascular disease such as Systemic Arterial Hypertension (SAH). Inflammatory cytokines are clearly involved in the pathogenesis of RA and correlated with SAH. Objective: It is necessary to understand whether the antihypertensive drugs have a dual effect as immunomodulators and which one is the best choice for RA SAH patients. Methods: Peripheral Blood Mononuclear Cells (PBMCs) from 16 RA patients were purified and stimulated or not stimulated with anti-CD3 and anti-CD28 mAB and were treated with Enalapril, Losartan and Valsartan at 100MUM. Patients were evaluated for clinical and laboratory variables including measures of disease activity by Clinical Disease Activity Index (CDAI) and Disease Activity Score (DAS28). Cytokines were quantified by ELISA sandwich. Results: Losartan was able to reduce levels of IFN-gamma (p = 0.0181), IL-6 (p = 0.0056), IL-17F (0.0046) and IL-22 (p = 0.0234) in RA patients. In addition, patients in remission and mild score (DAS28<3.2 and CDAI<10) had a better response to treatment. On the other hand, patients in moderate and severe activity had poor response to Losartan in cytokine inhibition. Conclusion: PBMCs from RA patients are responsive in inhibiting proinflammatory cytokines using Losartan better than Enalapril and Valsartan and it could be a better antihypertensive choice for patients with RA and systemic arterial hypertension treatment. PMID- 30288191 TI - Pelvic Tilt Angle Differences Between Symptom-Free Young Subjects and Elderly Patients Scheduled for THA: The Rationale for Tilt-Adjusted Acetabular Cup Implantation. AB - Background: The question whether Pelvic Tilt (PT) angles measured in the supine position are adequate for the alignment of the acetabular cup without an adjustment for anatomical differences between patients is of clinical importance. The aim of this work was to test for factors that can significantly affect PT angles. Methods: In the present retrospective cohort comparison, the PT angles of 12 Symptom-Free Young Subjects (SFYS) and 45 patients scheduled for Total Hip Arthroplasty (THA) were compared. The data was collected during two studies with the use of a novel smartphone-based navigated ultrasound measurement system. Multi-factorial analysis of variance was run to determine which factors significantly affect PT. Results: Body position (F= 126.65; P< 0.001) and group (SFYS vs. THA patients) (F= 17.52; P< 0.001) had significant main effects on PT. There was also a significant interaction between body position and group (F= 25.59; P< 0.001). The mean PT increased by 8.1 degrees from an interiorly to a neutral tilted position (P< 0.001) and 21.4 degrees from a neutral to a posteriorly tilted position (P< 0.001) with the transition from the supine into the upright position for the SFYS and THA patients, respectively. Conclusion: In both groups, PT changed significantly with a transition from the supine to the upright position. A position-dependent mean PT increase in the patient group showed that acetabular cup alignment based on PT in the supine position is not reliable without taking into consideration the inclination of the pelvis in standing position. This may lead to instability and dislocations. PMID- 30288193 TI - Emerging and Zoonotic Virus Challenges of Developing Nations.

AB - Background: A thickened coracohumeral ligament is a highly specific manifestation of, and primary restraint against external rotation in frozen shoulders. Objective: The purpose of this study was to evaluate the effects of complete arthroscopic coracohumeral ligament release on range of motion in frozen shoulder. Methods: Fifty-two consecutive shoulders in 52 patients were treated between April 2015 and June 2016. To evaluate solely glenohumeral range of motion, the scapula was fixed by an examiner with one hand (without palpating scapular motion), and range of motion was measured using a goniometer. For the first step, arthroscopic pancapsular release was performed in a beach-chair position with (Group 1) or without (Group 2) complete coracohumeral ligament release. For the final step, the remaining coracohumeral ligaments in Group 2 were released and the ranges of motion were compared to those in Group 1. Results: The average age of the patients was significantly higher in Group 1, but there were no significant differences between the two groups with respect to sex, affected side, preoperative range of motion, or American Shoulder and Elbow Society Score. Abduction, external rotation at adduction, and external and internal rotations at 90 degrees of flexion in Group 1 were significantly greater than those in Group 2. After the additional release of the remaining coracohumeral ligaments in Group 2, all ranges of motion were significantly recovered and there was no significant difference between the groups. Conclusion: Complete coracohumeral ligament release is a recommended intraoperative procedure for regaining full range of motion in frozen shoulders. PMID- 30288194 TI - Chandipura Viral Encephalitis: A Brief Review. AB - Introduction: In recent years, the Chandipura virus (CHPV) has emerged as an encephalitic pathogen and found associated with a number of outbreaks in different parts of India. Children under 15 years of age are most susceptible to natural infection. CHPV is emerging as a significant encephalitis, causing virus in the Indian subcontinent. Severe outbreaks caused by the virus have been reported from several parts of India. Expalanation: In the recent past, the noticeable association of CHPV with pediatric sporadic encephalitis cases as well as a number of outbreaks in Andhra Pradesh (2004, 2005, 2007 and 2008), Gujarat in (2005, 2009-12) and Vidarbha region of Maharashtra (2007, 2009-12) have been documented. Prevalence and seasonal activity of the virus in these regions are established by NIV through outbreak investigations, sero-survey and diagnosis of the referred clinical specimens. Recently CHPV has been isolated from pools of sand flies collected during outbreak investigations in Vidarbha region of Maharashtra. Since its discovery from India and above-mentioned activity of CHPV, it was suspected to be restricted only to India. Conclusion: However, CHPV has also been isolated from human cases during 1971-72 in Nigeria, and hedgehogs (Atelerix spiculus) during entomological surveillance in Senegal, Africa (1990 96) and recently referred samples from Bhutan and Nepal and from wild toque macaques (Macaca sinica) at Polonnaruwa, Sri Lanka during 1993 suggest its circulation in many tropical countries. Based on the limited study on vector related report, it appears that sandflies may be the principle vector. PMID- 30288196 TI - The Quest for Materials-Based Hydrogels with Antimicrobial and Antiviral Potentialities. AB - In recent years, the Antimicrobial Resistance (AMR) or Multidrug Resistance (MDR) and viral infections have become serious health issues, globally. Finally, after decades of negligence, the AMR/MDR and viral infection issues have now captured a worldwide attention of the global leaders, public health community, legalization authorities, academia, research-based organizations, and medicinal sector of the modern world, alike. Aiming to resolve these issues, various methodological approaches have been exploited, in the past several years. Among them, biomaterials-based therapeutic hydrogels are of supreme interests for an enhanced and efficient delivery in the current biomedical sector. Depending on the regulatory authorities and practices, the antibiotics consumption was expedited than ever before driven by rising and increasing access, across the globe. Though the emergence of AMR/MDR in microorganisms and emergence/reemergence of viral infections are considered as a natural phenomenon, however, these concerning issues have been driven by those mentioned above faulty human behavior. In this context, many scientists, around the globe, are working at wider spectrum to resolve this problematic issue, efficiently. A proper understanding of biological mechanisms is essential to combat this global threat to the living beings. In this review, an effort has been made to highlight the potent features of materials based hydrogels possessing antimicrobial and antiviral potentialities. The information is also given on the potential research activities, and possible mechanisms of actions of hydrogels are discussed with a closeup look at the future recommendations. PMID- 30288195 TI - Adaptation of Newcastle Disease Virus (NDV) in Feral Birds and their Potential Role in Interspecies Transmission. AB - Introduction: Newcastle Disease (ND), caused by Avian avulavirus 1 (AAvV 1, avulaviruses), is a notifiable disease throughout the world due to the economic impact on trading restrictions and its embargoes placed in endemic regions. The feral birds including aquatic/migratory birds and other wild birds may act as natural reservoir hosts of ND Viruses (NDVs) and may play a remarkable role in the spread of the virus in environment. In addition, other 19 avulaviruses namely: AAvV 2 to 20, have been potentially recognized from feral avian species. Expalantion: Many previous studies have investigated the field prevailing NDVs to adapt a wide range of susceptible host. Still the available data is not enough to declare the potential role of feral birds in transmission of the virus to poultry and/or other avian birds. In view of the latest evidence related to incidences of AAvVs in susceptible avian species, it is increasingly important to understand the potential of viruses to transmit within the domestic poultry and other avian hosts. Genomic and phylogenomic analysis of several investigations has shown the same (RK/RQRR?F) motif cleavage site among NDV isolates with same genotypes from domestic poultry and other wild hosts. So, the insight of this, various semi captive/free-ranging wild avian species could play a vital role in the dissemination of the virus, which is an important consideration to control the disease outbreaks. Insufficient data on AAvV 1 transmission from wild birds to poultry and vice versa is the main constraint to understand about its molecular biology and genomic potential to cause infection in all susceptible hosts. Conclusion: The current review details the pertinent features of several historical and contemporary aspects of NDVs and the vital role of feral birds in its molecular epidemiology and ecology. PMID- 30288198 TI - Epidemiologic Status of Picobirnavirus in India, A Less Explored Viral Disease. AB - Since the unexpected discovery of picobirnaviruses (PBV) in 1988, they have been reported in many animals including mammals and birds, which comprises both terrestrial and marine species. Due to their divergent characteristics to other viral taxa they are classified into a new family Picobirnaviridae. Although their pathogenicity and role in causing diarrhea still remains a question since they have been discovered in symptomatic and asymptomatic cases both. Recent studies employing state-of-art molecular tools have described their presence in various clinical samples, like stool samples from different mammals and birds, respiratory tracts of pigs and humans, sewage water, different foods, etc. Furthermore, their epidemiological status from different parts of the world in different hosts has also increased. Due to their diverse host and irregular host pattern their role in causing diarrhea remains alien. The heterogeneity nature can be ascribed to segmented genome of PBV, which renders them prone to continuous reassortment. Studies have been hampered on PBVs due to their non adaptability to cell culture system. Here, we describe the molecular epidemiological data on PBVs in India and discusses the overall status of surveillance studies carried out till date in India. PMID- 30288197 TI - Zoonotic Viral Diseases of Equines and Their Impact on Human and Animal Health. AB - Introduction: Zoonotic diseases are the infectious diseases that can be transmitted to human beings and vice versa from animals either directly or indirectly. These diseases can be caused by a range of organisms including bacteria, parasites, viruses and fungi. Viral diseases are highly infectious and capable of causing pandemics as evidenced by outbreaks of diseases like Ebola, Middle East Respiratory Syndrome, West Nile, SARS-Corona, Nipah, Hendra, Avian influenza and Swine influenza. Expalantion: Many viruses affecting equines are also important human pathogens. Diseases like Eastern equine encephalitis (EEE), Western equine encephalitis (WEE), and Venezuelan-equine encephalitis (VEE) are highly infectious and can be disseminated as aerosols. A large number of horses and human cases of VEE with fatal encephalitis have continuously occurred in Venezuela and Colombia. Vesicular stomatitis (VS) is prevalent in horses in North America and has zoonotic potential causing encephalitis in children. Hendra virus (HeV) causes respiratory and neurological disease and death in man and horses. Since its first outbreak in 1994, 53 disease incidents have been reported in Australia. West Nile fever has spread to many newer territories across continents during recent years.It has been described in Africa, Europe, South Asia, Oceania and North America. Japanese encephalitis has expanded horizons from Asia to western Pacific region including the eastern Indonesian archipelago, Papua New Guinea and Australia. Rabies is rare in horses but still a public health concern being a fatal disease. Equine influenza is historically not known to affect humans but many scientists have mixed opinions. Equine viral diseases of zoonotic importance and their impact on animal and human health have been elaborated in this article. Conclusion: Equine viral diseases though restricted to certain geographical areas have huge impact on equine and human health. Diseases like West Nile fever, Hendra, VS, VEE, EEE, JE, Rabies have the potential for spread and ability to cause disease in human. Equine influenza is historically not known to affect humans but some experimental and observational evidence show that H3N8 influenza virus has infected man. Despite our pursuit of understanding the complexity of the vector-host-pathogen mediating disease transmission, it is not possible to make generalized predictions concerning the degree of impact of disease emergence. A targeted, multidisciplinary effort is required to understand the risk factors for zoonosis and apply the interventions necessary to control it.

AB - Introduction: The work has been attempted to detect and genetically characterise the nature of Bovine Viral Diarrhea Virus (BVDV) isolates from the porcine population of the north east. Methods and Material: The samples have been collected over a two year period and are from areas where there is a mixed and integrated rearing of livestock in close proximity. The isolates were identified, cloned and sequenced using BVD specific genomic primers for two important domains viz., E-2 and 5' UTR. Results: Porcine BVD Sequences were analysed phylogenetically. Divergence in 3 sequences is noted in the 5' UTR region that are forming a clear outlier group while E-2 sequences are coming close to BVDV group but forming a separate cluster.

PMID- 30288200 TI - Japanese Encephalitis: A Brief Review on Indian Perspectives. AB - Introduction: Japanese encephalitis (JE) is recently declared as a notifiable disease in India due to its expanding geographical distribution. The disease notification facilitates effective implementation of preventive measures and case management. Expalantion: JE is a vector-borne disease that can be prevented by vaccine administration. It is caused by Japanese encephalitis virus (JEV), belonging to family Flaviviridae. Amongst the known etiological viral encephalitis agents, it is one of the leading viral agents of acute encephalitis syndrome in many Asian countries where it is identified to cause substantial morbidity and mortality as well as disability. Globally, it is responsible for approximately 68,000 clinical cases every year. Conclusion: In the absence of antivirals, patients are given supportive treatment to relieve and stabilize. Amongst available control strategies; vector control is resource intensive while animal and human vaccination are the most effective tool against the disease. This review highlights recent progress focusing challenges with diagnosis and prophylactic interventions. PMID- 30288202 TI - Teleburn: Designing A Telemedicine Application to Improve Burn Treatment. AB - Background: Due to the increasing rate of the burn injuries and a limited number of specialized treatment centers, providing medical advice and medical care at the point of need is necessary. The aim of the present study was to design and implement a teleburn system to enhance the quality of care for the burn patients. Methods: This study was completed in 2016. In order to design the system, information needs assessment was conducted by using a questionnaire. The participants of this phase were five specialists, five general practitioners, and 12 nurses. The setting of the study was the burn department of a public hospital and a burn center. The prototype of the system was designed based on the findings derived from the first phase, and the usability of the system was evaluated later. Results: The teleburn system was a web-based system with different sections for GPs/nurses and specialists. In total, 28 burn consultations were made successfully by using the system. The findings of the usability testing showed that most of the participants evaluated the system at a good level. The mean score for the specialists, general practitioners and nurses was 8.4+/-0.46, 7.7+/-0.39, and 7.5+/-0.51, respectively. Conclusion: Although it was the first time in the country that the teleburn system was designed and introduced to the clinicians, they seemed to be satisfied with using the system. This system could help general practitioners and nurses to receive specialist's advice on a timely manner to improve the treatment of the burn patients. However, more research should be conducted to determine the effectiveness of using this technology in the real work environment. PMID- 30288204 TI - Bilingualism in the Early Years: What the Science Says. AB - Many children in North America and around the world grow up exposed to two languages from an early age. Parents of bilingual infants and toddlers have important questions about the costs and benefits of early bilingualism, and how to best support language acquisition in their children. Here, we separate common myths from scientific findings to answer six of parents' most common questions about early bilingual development. PMID- 30288203 TI - Endocannabinoids and related N-acylethanolamines: biological activities and metabolism. AB - The plant Cannabis sativa contains cannabinoids represented by Delta9 tetrahydrocannabinol, which exert psychoactivity and immunomodulation through cannabinoid CB1 and CB2 receptors, respectively, in animal tissues. Arachidonoylethanolamide (also referred to as anandamide) and 2 arachidonoylglycerol (2-AG) are well known as two major endogenous agonists of these receptors (termed "endocannabinoids") and show various cannabimimetic bioactivities. However, only 2-AG is a full agonist for CB1 and CB2 and mediates retrograde signals at the synapse, strongly suggesting that 2-AG is physiologically more important than anandamide. The metabolic pathways of these two endocannabinoids are completely different. 2-AG is mostly produced from inositol phospholipids via diacylglycerol by phospholipase C and diacylglycerol lipase and then degraded by monoacylglycerol lipase. On the other hand, anandamide is concomitantly produced with larger amounts of other N acylethanolamines via N-acyl-phosphatidylethanolamines (NAPEs). Although this pathway consists of calcium-dependent N-acyltransferase and NAPE-hydrolyzing phospholipase D, recent studies revealed the involvement of several new enzymes. Quantitatively major N-acylethanolamines include palmitoylethanolamide and oleoylethanolamide, which do not bind to cannabinoid receptors but exert anti inflammatory, analgesic, and anorexic effects through receptors such as peroxisome proliferator-activated receptor alpha. The biosynthesis of these non endocannabinoid N-acylethanolamines rather than anandamide may be the primary significance of this pathway. Here, we provide an overview of the biological activities and metabolisms of endocannabinoids (2-AG and anandamide) and non endocannabinoid N-acylethanolamines.

PMID- 30288205 TI - Simulated climate change affects how biocrusts modulate water gains and desiccation dynamics after rainfall events. AB - Soil surface communities dominated by mosses, lichens and cyanobacteria (biocrusts) are common between vegetation patches in drylands worldwide, and are known to affect soil wetting and drying after rainfall events. While ongoing climate change is already warming and changing rainfall patterns of drylands in many regions, little is known on how these changes may affect the hydrological behaviour of biocrust-covered soils. We used eight years of continuous soil moisture and rainfall data from a climate change experiment in central Spain to explore how biocrusts modify soil water gains and losses after rainfall events under simulated changes in temperature (2.5 degrees C warming) and rainfall (33% reduction). Both rainfall amount and biocrust cover increased soil water gains after rainfall events, whereas experimental warming, rainfall intensity and initial soil moisture decreased them. Initial moisture, maximum temperature and biocrust cover, by means of enhancing potential evapotranspiration or by soil darkening, increased the drying rates and enhanced the exponential behaviour of the drying events. Meanwhile, warming reduced their exponential behaviour. The effects of climate change treatments on soil water gains and losses changed through time, with important differences between the first two years of the experiment and five years after its setup. These effects were mainly driven by the important reductions in biocrust cover and diversity observed under warming. Our results highlight the importance of long-term studies to understand soil moisture responses to ongoing climate change in drylands. PMID- 30288206 TI - Cyclodextrin-Promoted Fluorescence Detection of Aromatic Toxicants and Toxicant Metabolites in Commercial Milk Products. AB - The detection of polycyclic aromatic hydrocarbons (PAHs) and their metabolites in food and in agricultural sources is an important research objective due to the PAHs' known persistence, carcinogenicity, and toxicity. PAHs have been found in the milk of lactating cows, and in the leaves and stems of plants grown in PAH contaminated areas, thereby making their way into both cow milk and plant milk alternatives. Reported herein is the rapid, sensitive, and selective detection of 10 PAHs and PAH metabolites in a variety of cow milks and plant milk alternatives using fluorescence energy transfer from the PAH to a high quantum yield fluorophore, combined with subsequent array-based statistical analyses of the fluorescence emission signals. This system operates with high sensitivity (low micromolar detection limits), selectivity (100% differentiation even between structurally similar analytes), and general applicability (for both unmodified lipophilic PAHs and highly polar oxidized PAH metabolites, as well as for different cow and plant milk samples). These promising results show significant potential to be translated into solid-state devices for the rapid, sensitive, and selective detection of PAHs and their metabolites in complex, commercial food products. PMID- 30288208 TI - COMBINING PHENOTYPIC AND RESTING-STATE FMRI DATA FOR AUTISM CLASSIFICATION WITH RECURRENT NEURAL NETWORKS. AB - Accurate identification of autism spectrum disorder (ASD) from resting-state functional magnetic resonance imaging (rsfMRI) is a challenging task due in large part to the heterogeneity of ASD. Recent work has shown better classification accuracy using a recurrent neural network with rsfMRI time-series as inputs. However, phenotypic features, which are often available and likely carry predictive information, are excluded from the model, and combining such data with rsfMRI into the recurrent neural network is not a straightforward task. In this paper, we present several methodologies for incorporating phenotypic data with rsfMRI into a single deep learning framework for classifying ASD. We test the proposed architectures using a cross-validation framework on the large, heterogeneous first cohort from the Autism Brain Imaging Data Exchange. Our best model achieved an accuracy of 70.1%, outperforming prior work.

PMID- 30288218 TI - Link between a high k on for drug binding and a fast clinical action: to be or not to be? AB - Review articles on binding kinetics essentially focus on drugs that dissociate slowly from their target since this is required for the successful treatment of many pathophysiological conditions. Recently, the therapeutic benefit of a high k on (i.e. the second order association rate constant) has also been linked to fast association and to a fast clinical action. Other studies, however, called this assertion into question since additional factors, like the dosing paradigm and the binding mechanism, are important as well. The still ongoing reticence about integrating binding kinetics in lead optimization programs motivated us to critically review the link between the drug's kinetic rate constants and their in vitro and in vivo target occupancy profile, with special focus on k on. The presented simulations tally with a positive link between a drug's effective/observed association rate (which is quite easy to determine in vitro) and the swiftness of its clinical action. On the other hand, the simulations show that the k on-concept should not be confounded with the effective association process since increasing this parameter only enhances the drug's in vitro and in vivo association under certain conditions: the binding mechanism should be suitable, rebinding (and thus the factors within the target's micro-environment that favour this mechanism) should not be too prominent and the dosage should not be kept in par with the drug's affinity. Otherwise, increasing k on could be ineffective or even be counter-productive. PMID- 30288217 TI - Transfection by cationic gemini lipids and surfactants. AB - Diseases that are linked to defective genes or mutations can in principle be cured by gene therapy, in which damaged or absent genes are either repaired or replaced by new DNA in the nucleus of the cell. Related to this, disorders associated with elevated protein expression levels can be treated by RNA interference via the delivery of siRNA to the cytoplasm of cells. Polynucleotides can be brought into cells by viruses, but this is not without risk for the patient. Alternatively, DNA and RNA can be delivered by transfection, i.e. by non viral vector systems such as cationic surfactants, which are also referred to as cationic lipids. In this review, recent progress on cationic lipids as transfection vectors will be discussed, with special emphasis on geminis, surfactants with 2 head groups and 2 tails connected by a spacer. PMID- 30288221 TI - Development of subnanomolar-affinity serotonin 5-HT4 receptor ligands based on quinoline structures. AB - Two small series of quinoline derivatives were designed starting from previously published quinoline derivatives 7a and b in order to obtain information about their interaction with the 5-HT4R binding site. Initially, the structure of 7a and b was modified by replacing their basic moiety with that of partial agonist 4 (ML10302) or with that of reference ligand 6 (RS-67-333). Then, the aromatic moieties of 4-quinolinecarboxylates 7a, d-f, and h-k or 4-quinolinecarboxamides 7b, c, and g were modified into those of 2-quinolinecarboxamides 9a-e. Very interestingly, this structure-affinity relationship study led to the discovery of 7h-j as novel 5-HT4R ligands showing K i values in the subnanomolar range. The structures of all these compounds contain the N-butyl-4-piperidinylmethyl substituent, which appear to behave as an optimized basic moiety in the interaction of these 4-quinolinecarboxylates with the 5-HT4R binding site. However, this basic moiety was ineffective in providing 5-HT4R affinity in the corresponding 4-quinolinecarboxamide 7g, but it did in 2-quinolinecarboxamide ligands 9c-e. Thus, a subtle interrelationship of several structural parameters appeared to play a major role in the interaction of the ligands with the 5-HT4R binding site. They include the kind of basic moiety, the position of the carbonyl linking group with respect to the aromatic moiety and its orientation, which could be affected by the presence of the intramolecular H-bond as in compounds 9c e. PMID- 30288220 TI - Design, synthesis, and evaluation of bitopic arylpiperazine-phthalimides as selective dopamine D3 receptor agonists. AB - The dopamine D3 receptor (D3R) is a proven therapeutic target for the treatment of neurological and neuropsychiatric disorders. In particular, D3R-selective ligands that can eliminate side effects associated with dopamine D2 receptor (D2R) therapeutics have been validated. However, the high homology in signaling pathways and the sequence similarity between D2R and D3R have rendered the development of D3R-selective ligands challenging. Herein, we designed and synthesized a series of piperazine-phthalimide bitopic ligands based on a fragment-based and molecular docking inspired design. Compound 9i was identified as the most selective D3R ligand among these bitopic ligands. Its selectivity was improved compared to reference compounds 1 and 2 by 9- and 2-fold, respectively, and it was 21-fold more potent than compound 2. Molecular docking demonstrated that the orientation of Leu2.64 and Phe7.39 and the packing at the junction of helices may affect the specificity for D3R over D2R. Functional evaluation revealed that D3R-selective ligand 9i displayed a subpicomolar agonist activity at D3R with a 199-fold increase in potency compared to quinpirole. These results may be useful for the fragment-based design of bitopic compounds as selective D3R ligands. PMID- 30288222 TI - Design, synthesis, and evaluation of 4,5,6,7-tetrahydrobenzo[d]thiazole-based novel dual kinase inhibitors of CK2 and GSK3beta. AB - Casein kinase 2 (CK2) and glycogen synthase kinase-3beta (GSK3beta) are responsible for the phosphorylation of a tumor suppressor protein (PTEN) in a cooperative manner which causes its deactivation. Thus, it is essential to inhibit both kinases simultaneously to prevent PTEN deactivation more efficiently. In this study, we have designed a novel lead from Hit15 which was identified in silico as a dual kinase inhibitor against CK2 and GSK3beta through our previous study. The dataset of structural analogs of the lead was designed and confirmed by pharmacophore mapping and molecular docking. The screened analogs were considered further and a series of "tetrahydrobenzo[d]thiazoles" were synthesized. Compound 1g has shown highest dual kinase inhibitory activity at a concentration of 1.9 MUM against CK2 and 0.67 MUM against GSK3beta. Our results suggest that the presence of a carboxyl group at the meta position of the phenyl ring plays a vital role in dual kinase inhibition. PMID- 30288219 TI - beta-lactam/beta-lactamase inhibitor combinations: an update. AB - Antibiotic resistance caused by beta-lactamase production continues to present a growing challenge to the efficacy of beta-lactams and their role as the most important class of clinically used antibiotics. In response to this threat however, only a handful of beta-lactamase inhibitors have been introduced to the market over the past thirty years. The first-generation beta-lactamase inhibitors (clavulanic acid, sulbactam and tazobactam) are all beta-lactam derivatives and work primarily by inactivating class A and some class C serine beta-lactamases. The newer generations of beta-lactamase inhibitors including avibactam and vaborbactam are based on non-beta-lactam structures and their spectrum of inhibition is extended to KPC as an important class A carbapenemase. Despite these advances several class D and virtually all important class B beta lactamases are resistant to existing inhibitors. The present review provides an overview of recent FDA-approved beta-lactam/beta-lactamase inhibitor combinations as well as an update on research efforts aimed at the discovery and development of novel beta-lactamase inhibitors. PMID- 30288223 TI - Phenothiazine antioxidants increase mitochondrial biogenesis and frataxin levels in Friedreich's ataxia cells. AB - Friedreich's ataxia (FRDA) is a progressive neurodegenerative disease that is linked to transcriptional repression of the nuclear FXN gene encoding the essential mitochondrial protein frataxin (FXN). Compounds that increase frataxin levels may enable effective therapeutic intervention for blunting disease progression. Recently, we showed that lipophilic methylene violet (MV) and methylene blue (MB) analogues both conferred benefit to cultured FRDA cells in several regards, including ROS suppression, maintenance of mitochondrial membrane potential and increased ATP production. Some of the MB analogues were also shown to promote increased frataxin levels and mitochondrial biogenesis. Presently, we report that two of the MV analogues studied previously (1 and 2) also increased frataxin levels and mitochondrial biogenesis significantly. Because the substitution pattern in the two series of compounds was not the same, we also prepared new MV derivatives having the same substitution pattern as the original MB derivatives studied to enable a more direct comparison. Two of the new MV compounds, 4b and 6b, exhibited enhanced antioxidant capability, increased frataxin levels and mitochondrial biogenesis, and improved aconitase activity. These encouraging findings demonstrated that the MV analogues had better overall activity with less cytotoxicity. PMID- 30288224 TI - Glycyrrhizic acid from licorice down-regulates inflammatory responses via blocking MAPK and PI3K/Akt-dependent NF-kappaB signalling pathways in TPA-induced skin inflammation. AB - Glycyrrhizinic acid (GA), a principal component derived from licorice which is used extensively as a natural sweetener and traditional folk herbal medicine, is attracting considerable attention because of its broad range of bioactivities. However, the anti-inflammatory mechanism of GA on 12-O-tetradecanoylphorbol-13 acetate (TPA)-mediated skin inflammation has not been elucidated. Herein, we investigated the anti-inflammatory activity of GA by using a TPA-induced mouse ear model. It was indicated that GA, applied topically onto mouse ears, effectively inhibited the TPA-mediated expressions of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in a dose-dependent manner, respectively. Mechanistic investigations demonstrated that GA down-regulated the expressions of IkappaBalpha and p65 and blocked the phosphorylation of IkappaBalpha and p65 in TPA-induced mouse skin. Moreover, GA significantly inhibited the TPA-mediated activation of extracellular signal-regulated kinase (ERK1/2), p38 mitogen-activated protein kinase (MAPK), and phosphatidylinositol 3 kinase (PI3K)/Akt, which are upstream of nuclear factor-kB (NF-kappaB). Taken together, these results indicated that GA, being of natural origin, may be a potential agent for preventing inflammatory diseases.

AB - A novel series of sulfonamide derivatives, coupled with a salicylamide scaffold, was designed and synthesized. The structures of the synthesized compounds were established using 1H NMR, 13C NMR and high-resolution mass spectroscopy. The synthesized compounds were tested in vitro against five types of human cell lines. Two were breast adenocarcinoma, including the hormone-dependent MCF-7 and the hormone-independent MDA-MB-231. The others were the colorectal adenocarcinoma Caco-2, the carcinoma HCT-116 and the immortalized retinal-pigmented epithelium, hTERT-RPE1. Nine sulfonamides were able to inhibit the growth of the four tested cancer cells. Compound 33 was the most active against the selected colon cancer (Caco-2 and HCT-116) subtypes, while compound 24 showed the best efficacy against the examined breast cancer (MCF-7 and MDA-MB-231) cells. The selectivity index introduced compounds 24 and 33 as having the best selectivity among the breast and colon subtypes, respectively. In vitro tubulin polymerization experiments and flow cytometric assays showed that compounds 24 and 33 led to cell cycle arrest at the G2/M phase in a dose-dependent manner by effectively inhibiting tubulin polymerization. Furthermore, the results of the molecular docking studies indicate that this class of compounds can bind to the colchicine-binding site of tubulin. PMID- 30288226 TI - Novel organophosphorus aminopyrimidines as unique structural DNA-targeting membrane active inhibitors towards drug-resistant methicillin-resistant Staphylococcus aureus. AB - A series of novel unique structural organophosphorus aminopyrimidines were developed as potential DNA-targeting membrane active inhibitors through an efficient one-pot procedure from aldehydes, phosphonate and aminopyrimidine. The biological assay revealed that some of the prepared compounds displayed antibacterial activities. In particular, imidazole derivative 2c exhibited more potent inhibitory activity against MRSA with an MIC value of 4 MUg mL-1 in comparison with the clinical drugs chloromycin and norfloxacin. Experiments revealed that the active molecule 2c had the ability to rapidly kill the tested strains without obviously triggering the development of bacterial resistance, showed low toxicity to L929 cells and could disturb the cell membrane. The molecular docking study discovered that compound 2c could bind with DNA gyrase via hydrogen bonds and other weak interactions. Further exploration disclosed that the active molecule 2c could also effectively intercalate into MRSA DNA and form a steady 2c-DNA supramolecular complex, which might further block DNA replication to exert powerful antibacterial effects. PMID- 30288227 TI - Lipophilicity prediction of peptides and peptide derivatives by consensus machine learning. AB - Lipophilicity prediction is routinely applied to small molecules and presents a working alternative to experimental log P or log D determination. For compounds outside the domain of classical medicinal chemistry these predictions lack accuracy, advocating the development of bespoke in silico approaches. Peptides and their derivatives and mimetics fill the structural gap between small synthetic drugs and genetically engineered macromolecules. Here, we present a data-driven machine learning method for peptide log D 7.4 prediction. A model for estimating the lipophilicity of short linear peptides consisting of natural amino acids was developed. In a prospective test, we obtained accurate predictions for a set of newly synthesized linear tri- to hexapeptides. Further model development focused on more complex peptide mimetics from the AstraZeneca compound collection. The results obtained demonstrate the applicability of the new prediction model to peptides and peptide derivatives in a log D 7.4 range of approximately -3 to 5, with superior accuracy to established lipophilicity models for small molecules. PMID- 30288228 TI - 2-Aminobenzimidazoles as antibiofilm agents against Salmonella enterica serovar Typhimurium. AB - Serovars within the species Salmonella enterica are some of the most common food and water-borne pathogens worldwide. Some S. enterica serovars have shown a remarkable ability to persist both inside and outside the human body. Salmonella enterica serovar Typhi can cause chronic, asymptomatic infection of the human gallbladder. This organism's ability to survive inside the gallbladder centers around its ability to form biofilms on gallstone surfaces. Currently, chronic carriage of S. Typhi is treated by invasive methods, which are not well suited to areas where Salmonella carriage is prevalent. Herein, we report 2 aminobenzimidazoles that inhibit S. enterica serovar Typhimurium (a surrogate for S. Typhi) biofilm formation in low micromolar concentrations. Modifications to the head, tail, and linker regions of the original hit compound elucidated new, more effective analogues that inhibit S. Typhimurium biofilm formation while being non-toxic to planktonic bacterial growth.

AB - A series of fifteen novel dihydropyrimidinone hybrid compounds were synthesized in good yields via a multicomponent reaction combined with the Huisgen reaction. The antiproliferative activity was investigated against nine tumor cell lines, and four hybrid compounds (TGI < 10 MUM) showed promising antiproliferative activity against the tumor cell lines OVCAR-3 (ovarian), UACC-62 (melanoma) and U251 (glioma). Several hybrid compounds assayed have high TGI values (TGI 147.92 507.82) for the human keratinocyte cell line (HaCat), which reveals selectivity to cancer cells. PMID- 30288231 TI - Enantioselective aza-Friedel-Crafts reaction of furan with alpha-ketimino esters induced by a conjugated double hydrogen bond network of chiral bis(phosphoric acid) catalysts. AB - Chiral C 2- and C 1-symmetric BINOL-derived bis(phosphoric acid) catalysts, which have OP([double bond, length as m-dash]O)(OH)2/OP([double bond, length as m dash]O)(OH)(OR) moieties at the 2,2'-positions, were developed and used for the enantioselective aza-Friedel-Crafts reaction of 2-methoxyfuran with alpha ketimino esters for the first time. The intramolecular conjugated double hydrogen bond network is a key to increasing the Bronsted acidity and preventing deactivation of the catalysts. Highly functionalized alpha-amino acid derivatives with a chiral quaternary carbon center could be transformed into versatile optically active N- and O-heterocycles and an alpha-aryl-substituted serine. PMID- 30288232 TI - N-Heterocyclic carbenes as chiral Bronsted base catalysts: a highly diastereo- and enantioselective 1,6-addition reaction. AB - Highly diastereo- and enantioselective 1,6-addition of 1,3-ketoamides to p quinone methides (p-QMs) using chiral NHCs as Bronsted base catalysts is developed. The reaction is based on the utilization of a 1,3-ketoamide having acidic N-H that forms a chiral ion-pair consisting of the enolate and the azolium ion. Different beta-ketoamides and functionalized p-QMs are applicable to the reaction. Synthetic application of the method is demonstrated via the preparation of highly enantioenriched beta and gamma-lactam derivatives. PMID- 30288233 TI - Antibody drug conjugates (ADCs) charged with HDAC inhibitor for targeted epigenetic modulation. AB - We describe here two novel antibody-drug conjugates loaded with the HDAC inhibitor ST7612AA1 (IC50 equal to 0.07 MUM on NCI-H460 cells), a thiol-based molecule with a moderate toxicity in vivo. Two payloads were prepared using cleavable and non-cleavable linkers. After anchoring to cetuximab through amide bond with lysines, the resulting HDAC inhibitor-antibody conjugates showed ability to recognize EGFR and efficient internalization in tumor cells. Both ADCs induced sensible increment of histones 3 and 4 and alpha-tubulin acetylation. Animal models of human solid tumors showed high anti-tumor efficacy of the conjugates without the toxicity generally observed with traditional ADCs delivering highly potent cytotoxic drugs. These compounds, the first ADCs charged with not highly cytotoxic warheads, are potentially suitable for epigenetic modulation, extending the ADC strategy to the targeted delivery of HDAC inhibitors with many possible therapeutic applications beyond cancer. PMID- 30288234 TI - OH formation and H2 adsorption at the liquid water-Pt(111) interface. AB - The liquid water-Pt(111) interface is studied with constant temperature ab initio molecular dynamics to explore the importance of liquid water dynamics of catalytic reactions such as the oxygen reduction reaction in PEM fuel cells. The structure and energetics of hydroxyls formed at the liquid water-Pt(111) interface are found to be significantly different from those of the hydroxyl formed on a bare Pt(111) surface and the hydroxyl formed on a Pt(111) surface with a static water layer. We identify 1/12 ML *OH, 5/12 ML *OH and 2/3 ML *OH as particularly stable hydroxyl coverages in highly dynamic liquid water environments, which - contrary to static water-hydroxyl models - contain adjacent uncovered Pt sites. Atomic surface oxygen is found to be unstable in the presence of liquid water, in contrast to static atomic level simulations. These results give an improved understanding of hydroxide and surface oxide formation from Pt(111) cyclic voltammetry and allow us to draw detailed connections between the electrostatic potential and the interface structure. The study of hydrogen adsorption at the liquid water-Pt(111) interface finds competitive adsorption between the adsorbed hydrogen atoms and water molecules. This does not adhere with experimental observations, and this indicates that the Pt(111) surface has to be negatively charged for a correct description of the liquid water-Pt(111) interface at potentials where hydrogen adsorption occurs.

AB - A sustainable transformation of white phosphorus (P4) into chemicals of higher value is one of the key aspects in modern phosphorus research. Even though the chemistry of P4 has been investigated for many decades, its chemical reactivity towards the simplest electrophile, the proton, is still virtually unknown. Based on quantum-chemical predictions, we report for the first time the successful protonation of P4 by the Bronsted acid H[Al(OTeF5)4](solv). Our spectroscopic results are in agreement with acid-mediated activation of P4 under protonation of an edge of the P4-tetrahedron and formation of a three-center two-electron P-H-P bond. These investigations are of fundamental interest as they permit the activation of P4 with the simplest electrophile as a new prototype reaction for this molecule. PMID- 30288236 TI - A fluorescent methylation-switchable probe for highly sensitive analysis of FTO N 6-methyladenosine demethylase activity in cells. AB - N 6-Methyladenosine (m6A) is one of the most abundant epigenetic modifications on mRNA. It is dynamically regulated by the m6A demethylases FTO and ALKBH5, which are currently attracting intense medical interest because of their strong association with several human diseases. Despite their clinical significance, the molecular mechanisms of m6A demethylases remain unclear, hence there is tremendous interest in developing analytical tools to facilitate their functional studies, with a longer term view of validating their therapeutic potentials. To date, no method exists which permits the analysis of m6A-demethylase activity in cells. To overcome this challenge, herein, we describe the first example of a fluorescent m6A-switchable oligonucleotide probe, which enables the direct detection of FTO demethylase activity both in vitro and in living cells. The m6A probe provides a simple, yet powerful visual tool for highly sensitive detection of demethylase activity. Through the use of m6A-probe, we were able to achieve real-time imaging and single-cell flow cytometry analyses of FTO activity in HepG2 cells. We also successfully applied the probe to monitor dynamic changes in FTO activity and m6A methylation levels during 3T3-L1 pre-adipocyte differentiation. The strategy outlined here is highly versatile and may, in principle, be adapted to the study of a range of RNA demethylases and, more widely, other RNA modifying enzymes. To the best of our knowledge, the present study represents not only the first assay for monitoring FTO activity in living cells, but also a new strategy for sensing m6A methylation dynamics. PMID- 30288237 TI - Conformational selectivity and high-affinity binding in the complexation of N phenyl amides in water by a phenyl extended calix[4]pyrrole. AB - We describe the synthesis of a tetrapyridinium phenyl extended calix[4]pyrrole that is soluble in neutral water solution at mM concentrations. We show that, in pure water, the synthesized calix[4]pyrrole receptor selectively binds the cis (E) conformers of secondary N-phenyl-amides and tertiary N-methyl-N-phenyl formamide with binding affinities larger than 103 M-1. The conformational selectivity is remarkable owing to the energetic preference of amides to adopt the trans-(Z) conformation in solution. In this respect, we used two binding models for the mathematical analyses of the titration data and calculated apparent and intrinsic binding constants. The combined action of hydrogen bonding and the hydrophobic effect that operates in the binding of the amides in water is responsible for the large affinities displayed by the receptor. PMID- 30288238 TI - A mild light-induced cleavage of the S-O bond of aryl sulfonate esters enables efficient sulfonylation of vinylarenes. AB - A new mode of S-O bond activation has been discovered, which constitutes novel reactivity of easily available and bench-stable arylsulfonate phenol esters.

PMID- 30288239 TI - Tetrazine-mediated bioorthogonal prodrug-prodrug activation. AB - The selective and biocompatible activation of prodrugs within complex biological systems remains a key challenge in medical chemistry and chemical biology. Herein we report, for the first time, a dual prodrug activation strategy that fully satisfies the principle of bioorthogonality by the symbiotic formation of two active drugs. This dual and traceless prodrug activation strategy takes advantage of the INVDA chemistry of tetrazines (here a prodrug), generating a pyridazine based miR21 inhibitor and the anti-cancer drug camptothecin and offers a new concept in prodrug activation. PMID- 30288240 TI - An "all-in-one" antitumor and anti-recurrence/metastasis nanomedicine with multi drug co-loading and burst drug release for multi-modality therapy. AB - Drug-loading often suffers from tedious procedures, limited loading efficiency, slow release, and therefore a low curative effect. Cancer easily recurs and metastasizes even after a solid tumor is removed. Herein, we report a simple strategy with multi-drug co-loading and burst drug release for a high curative effect and anti-recurrence/metastasis. CuS nanoparticles, protoporphyrin IX, and doxorubicin were added to the precursors of ZIF-8 with one-pot co-loading during the formation of ZIF-8 for chemo-, photothermal-, and photodynamic-therapy to eliminate solid tumors. Negative CpG, as a kind of immune adjuvant, was adsorbed on the positive surface of ZIF-8 to inhibit the recurrence and metastasis of tumors with its long-term immune response. Precision treatment with one-pot multi drug co-loading, controllable drug delivery, and multi-modality therapy may be anticipated by this versatile strategy. PMID- 30288241 TI - The hydrogen atom transfer reactivity of sulfinic acids. AB - Sulfinic acids (RSO2H) have a reputation for being difficult reagents due to their facile autoxidation. Nevertheless, they have recently been employed as key reagents in a variety of useful radical chain reactions. To account for this paradox and enable further development of radical reactions employing sulfinic acids, we have characterized the thermodynamics and kinetics of their H-atom transfer reactions for the first time. The O-H bond dissociation enthalpy (BDE) of sulfinic acids was determined by radical equilibration to be ~78 kcal mol-1; roughly halfway between the RS-H BDE in thiols (~87 kcal mol-1) and RSO-H BDE in sulfenic acids (~70 kcal mol-1). Regardless, RSH, RSOH and RSO2H have relatively similar inherent H-atom transfer reactivity to alkyl radicals (~106 M-1 s-1). Counter-intuitively, the trend in rate constants with more reactive alkoxyl radicals follows the reaction energetics: ~108 M-1 s-1 for RSO2H, midway between thiols (~107 M-1 s-1) and sulfenic acids (~109 M-1 s-1). Importantly, since sulfinic and sulfenic acids are very strong H-bond donors (alphaH2 ~ 0.63 and 0.55, respectively), their reactivity is greatly attenuated in H-bond accepting solvents, whereas the reactivity of thiols is largely solvent-independent. Efforts to measure rate constants for the reactions of sulfinic acids with alkylperoxyl radicals were unsuccessful. Computations predict these reactions to be surprisingly slow; ~1000-times slower than for thiols and ~10 000 000-times slower than for sulfenic acids. On the other hand, the reaction of sulfinic acids with sulfonylperoxyl radicals - which propagate sulfinic acid autoxidation - is predicted to be almost diffusion-controlled. In fact, the rate-determining step in sulfinic acid autoxidation, and the reason they can be used for productive chemistry, is the relatively slow reaction of propagating sulfonyl radicals with O2 (~106 M-1 s-1).

AB - We report a photocatalytic version of the Barbier type reaction using readily available allyl or benzyl bromides and aromatic aldehydes or ketones as starting materials to generate allylic or benzylic alcohols. The reaction proceeds at room temperature under visible light irradiation with the organic dye 3,7-di(4 biphenyl)1-naphthalene-10-phenoxazine as a photocatalyst and DIPEA as sacrificial electron donor. The proposed cross-coupling mechanism of a ketyl- and an allyl or benzyl radical is supported by spectroscopic investigations and cyclic voltammetry measurements. PMID- 30288243 TI - Phosphorescent iridium(iii) complexes capable of imaging and distinguishing between exogenous and endogenous analytes in living cells. AB - Many luminescent probes have been developed for intracellular imaging and sensing. During cellular luminescence sensing, it is difficult to distinguish species generated inside cells from those internalized from extracellular environments since they are chemically the same and lead to the same luminescence response of the probes. Considering that endogenous species usually give more information about the physiological and pathological parameters of the cells while internalized species often reflect the extracellular environmental conditions, we herein reported a series of cyclometalated iridium(iii) complexes as phosphorescent probes that are partially retained in the cell membrane during their cellular uptake. The utilization of the probes for sensing and distinguishing between exogenous and endogenous analytes has been demonstrated using hypoxia and hypochlorite as two examples of target analytes. The endogenous analytes lead to the luminescence response of the intracellular probes while the exogenous analytes are reported by the probes retained in the cell membrane during their internalization. PMID- 30288244 TI - Probing cytoplasmic and nuclear microRNAs in single living cells via plasmonic affinity sandwich assay. AB - MicroRNAs (miRNAs) regulate the expression of mRNAs in cells. The determination of subcellular miRNAs in single living cells is essential for understanding the subcellular localizations and functions of miRNAs as well as the microheterogeneity of cells. However, current approaches fail either to keep the cells alive or maintain their original cellular composition or are unable to provide subcellular resolution. Herein, we presented a new approach, called plasmonic affinity sandwich assay (PASA), for rapid and ultrasensitive probing of trace cytoplasmic and nuclear miRNAs in single living cells. It combined efficient in vivo subcellular extraction with ultrasensitive plasmon-enhanced Raman scattering (PERS) detection. By virtue of a micromanipulator, target miRNAs in the cytoplasm and nucleus were first specifically extracted from single living cells by gold thinlayer-coated glass microprobes modified with a half complementary sequence to the target miRNA and then, they were labelled with silver nanotags modified with a Raman reporter and the other half complement. Sandwich-like complexes of extraction sequence-target miRNA-labelling sequence were formed on the extraction microprobe, which were subjected to PERS detection. The subcellular resolution of this approach was confirmed with miR-29b (predominantly localized in the nuclei) and miR-29a (mainly located in the cytoplasm), whereas the quantitative capability was verified with three cytoplasmic miRNAs including miR-21, miR-155 and miR-203. This approach obviated tedious steps such as subcellular fractionation and enzymatic amplification, and it required only 10 min. It could be a promising tool to provide insights into subcellular localizations, functions and microheterogeneity of miRNAs. PMID- 30288245 TI - Overcoming conservation in TALE-DNA interactions: a minimal repeat scaffold enables selective recognition of an oxidized 5-methylcytosine. AB - Transcription-activator-like effectors (TALEs) are repeat-based proteins featuring programmable DNA binding. The repulsion of TALE repeats by 5 methylcytosine (5mC) and its oxidized forms makes TALEs potential probes for their programmable analysis. However, this potential has been limited by the inability to engineer repeats capable of actual, fully selective binding of an (oxidized) 5mC: the extremely conserved and simple nucleobase recognition mode of TALE repeats and their extensive involvement in inter-repeat interactions that stabilize the TALE fold represent major engineering hurdles. We evaluated libraries of alternative, strongly truncated repeat scaffolds and discovered a repeat that selectively recognizes 5-carboxylcytosine (5caC), enabling construction of the first programmable receptors for an oxidized 5mC. In computational studies, this unusual scaffold executes a dual function via a critical arginine that provides inter-repeat stabilization and selectively interacts with the 5caC carboxyl group via a salt-bridge. These findings argue for an unexpected adaptability of TALE repeats and provide a new impulse for the design of programmable probes for nucleobases beyond A, G, T and C. PMID- 30288246 TI - Carrier-doping as a tool to probe the electronic structure and multi-carrier recombination dynamics in heterostructured colloidal nanocrystals. AB - Heterostructured colloidal nanocrystals, such as core/shells and dot-in-rods, enable new spectral and dynamic properties otherwise unachievable with single component nanocrystals or quantum dots (QDs). For example, the electron and hole wavefunctions can be engineered such that they are either both confined in the same domain or (partially) separated over different domains in the heterostructures, which are the so-called type I or (quasi-) type II localization regimes, respectively. A critical factor dictating the carrier localization regime is the band alignment or electronic structure of the heterostructure, which, however, is difficult to measure and hence is often ambiguous. In this work, using CdSe@CdS dot-in-rods (DIRs) as a model system, we show that band edge carrier-doping is a simple-yet-powerful tool to probe the electronic structure of heterostructures. By doping an electron into the CdSe core and then observing whether the doped electron bleaches band edge absorption of only the core or those of both the core and shell, we can easily differentiate the type I and quasi-type II structures. A systematic study of DIRs with various dimensions shows that the extent of electron wavefunction delocalization can be tuned by the core sizes and rod diameters. Comparison with the electronic structure determined from transient absorption measurements also reveals the important role of electron-hole binding in affecting the delocalization of electron wavefunction. In addition to probing the electronic structure, the doped electron allows for studying multi-carrier recombination dynamics in these heterostructures which plays a vital role in their many optical and optoelectronic applications. Specifically, by comparing the band edge exciton recombination kinetics of the doped and neutral DIRs, we can extract the negative trion lifetime, which can be further used to derive the positive trion lifetime when combined with biexciton lifetime measurements. These lifetimes also depend sensitively on the core sizes and rod diameters of the DIRs. PMID- 30288248 TI - Performing DNA nanotechnology operations on a zebrafish. AB - Nanoscale engineering of surfaces is becoming an indispensable technique to modify membranes and, thus cellular behaviour. Here, such membrane engineering related was explored on the surface of a living animal using DNA nanotechnology. We demonstrate the immobilization of oligonucleotides functionalized with a membrane anchor on 2 day old zebrafish. The protruding single-stranded DNA on the skin of zebrafish served as a handle for complementary DNAs, which allowed the attachment of small molecule cargo, liposomes and dynamic relabeling by DNA hybridization protocols. Robust anchoring of the oligonucleotides was proven as DNA-based amplification processes were successfully performed on the outer membrane of the zebrafish enabling the multiplication of surface functionalities from a single DNA-anchoring unit and the dramatic improvement of fluorescent labeling of these animals. As zebrafish are becoming an alternative to animal models in drug development, toxicology and nanoparticles characterization, we believe the platform presented here allows amalgamation of DNA nanotechnology tools with live animals and this opens up yet unexplored avenues like efficient bio-barcoding as well as in vivo tracking. PMID- 30288247 TI - Tricarbocyanine N-triazoles: the scaffold-of-choice for long-term near-infrared imaging of immune cells in vivo. AB - Herein tricarbocyanine N-triazoles are first described as a rationally-designed near-infrared (NIR) structure overcoming the brightness and photostability limitations of tricarbocyanines for long-term in vivo imaging. The straightforward synthetic approach and the wide availability of alkynes makes this strategy a versatile methodology for the preparation of highly stable N substituted tricarbocyanines. Furthermore, we validated CIR38M as a non transferable marker to monitor the fate of therapeutic T cells non-invasively in vivo, showing enhanced performance over conventional NIR fluorophores (i.e. DiR, IR800CW and indocyanine green) as well as compatibility with human cells for translational studies. CIR38M is able to track over time smaller numbers of T cells than current NIR agents, and to visualise antigen-driven accumulation of immune cells at specific sites in vivo. This chemical technology will improve longitudinal imaging studies to assess the efficacy of cell-based immunotherapies in preclinical models and in human samples. PMID- 30288249 TI - Between single ion magnets and macromolecules: a polymer/transition metal-based semi-solid solution. AB - The creation of functional magnetic materials for application in high-density memory storage or in the new field of molecular spintronics is a matter of widespread interest among the material research community. Herein, we describe a new approach that combines the qualities of single ion magnets, displaying slow magnetic relaxations, and the merits of polymers, being easy to process and widely used to produce thin films. Basing the idea on cobalt(ii) ions and pyridine-based single ion magnets, a new macromolecular magnetic material was obtained - a polymeric matrix of poly(4-vinylpyridine) (P4VP) cross-linked by a cobalt(ii) salt bound within it, effectively forming a network of single ion magnets, with field-induced magnetic relaxations preserved in both bulk and thin film forms. The binding of cobalt is confirmed by a series of methods, like secondary ion mass spectroscopy or high-resolution X-ray photoelectron spectroscopy. The magnetic relaxation times, up to 5 * 10-6 s, are controllable simply by dilution, making this new material a semi-solid solution. By this approach, a new path is formed to connect molecular magnetism and polymer science, showing that the easy polymer processing can be used in forming self organizing functional magnetic thin films.

AB - Background: Mycobacterium smegmatis, a rapidly growing non-tuberculosis mycobacterium, is a good model for studying the pathogenesis of tuberculosis because of its genetic similarity to Mycobacterium tuberculosis (Mtb). Macrophages remove mycobacteria during an infection. Macrophage apoptosis is a host defense mechanism against intracellular bacteria. We have reported that endoplasmic reticulum (ER) stress is an important host defense mechanism against Mtb infection. Results: In this study, we found that M. smegmatis induced strong ER stress. M. smegmatis-induced reactive oxygen species (ROS) play a critical role in the induction of ER stress-mediated apoptosis. Pretreatment with an ROS scavenger suppressed M. smegmatis-induced ER stress. Elimination of ROS decreased the ER stress response and significantly increased the intracellular survival of M. smegmatis. Interestingly, inhibition of phagocytosis significantly decreased ROS synthesis, ER stress response induction, and cytokine production. Conclusions: Phagocytosis of M. smegmatis induces ROS production, leading to production of proinflammatory cytokines. Phagocytosis-induced ROS is associated with the M. smegmatis-mediated ER stress response in macrophages. Therefore, phagocytosis plays a critical role in the induction of ER stress-mediated apoptosis during mycobacterial infection. PMID- 30288254 TI - Shape memory polymers with visible and near-infrared imaging modalities: Synthesis, characterization and in vitro analysis. AB - Shape memory polymers (SMPs) are promising for non-invasive medical devices and tissue scaffolds, but are limited by a lack of visibility under clinical imaging. Fluorescent dyes are an alternative to radiocontrast agents in medical applications, they can be utilized in chemical sensors and monitors and may be anti-microbial agents. Thus, a fluorescent SMP could be a highly valuable biomaterial system. Here, we show that four fluorescent dyes (phloxine B (PhB), eosin Y (Eos), indocyanine green(IcG), and calcein (Cal)) can be crosslinked into the polymer backbone to enhance material optical properties without alteration of shape memory and thermomechanical properties. Examinations of the emission wavelengths of the materials compared with the dye solutions showed a slight red shift in the peak emissions, indicative of crosslinking of the material. Quantitative analysis revealed that PhB enabled visibility through 1 cm of blood and through soft tissue. We also demonstrate the utility of these methods in combination with radio-opaque microparticle additives and the use of laser induced shape recovery to allow for rapid shape recovery below the glass transition temperature. The crosslinking of fluorescent dyes into the SMP enables tuning of physical properties and shape memory and independently of the fluorescence functionality. This fluorescent SMP biomaterial system allows for use of multiple imaging modalities with potential application in minimally invasive medical devices. PMID- 30288252 TI - Gene expression analysis of potential morphogen signalling modifying factors in Panarthropoda. AB - Background: Morphogen signalling represents a key mechanism of developmental processes during animal development. Previously, several evolutionary conserved morphogen signalling pathways have been identified, and their players such as the morphogen receptors, morphogen modulating factors (MMFs) and the morphogens themselves have been studied. MMFs are factors that regulate morphogen distribution and activity. The interactions of MMFs with different morphogen signalling pathways such as Wnt signalling, Hedgehog (Hh) signalling and Decapentaplegic (Dpp) signalling are complex because some of the MMFs have been shown to interact with more than one signalling pathway, and depending on genetic context, to have different, biphasic or even opposing function. This complicates the interpretation of expression data and functional data of MMFs and may be one reason why data on MMFs in other arthropods than Drosophila are scarce or totally lacking. Results: As a first step to a better understanding of the potential roles of MMFs in arthropod development, we investigate here the embryonic expression patterns of division abnormally delayed (dally), dally-like protein (dlp), shifted (shf) and secreted frizzled-related protein 125 (sFRP125) and sFRP34 in the beetle Tribolium castaneum, the spider Parasteatoda tepidariorum, the millipede Glomeris marginata and the onychophoran Euperipatoides kanangrensis. This pioneer study represents the first comprehensive comparative data set of these genes in panarthropods. Conclusions: Expression profiles reveal a high degree of diversity, suggesting that MMFs may represent highly evolvable nodes in otherwise conserved gene regulatory networks. Conserved aspects of MMF expression, however, appear to concern function in segmentation and limb development, two of the key topics of evolutionary developmental research.

The current study was performed to assess phenotypic characters of antibiotic resistance and genotyping pattern of vacA, cagA, iceA, oipA and babA2 alleles amongst the H. pylori strains isolated from raw milk. Methods: Six-hundred and thirty raw milk samples were collected and cultured on Wilkins Chalgren anaerobe media. Antibiotic resistance and genotyping patterns were studied using disk diffusion and PCR, respectively. Results: Sixty-seven out of 630 (10.63%) raw milk samples were positive for H. pylori. Ovine raw milk (17.27%) samples had the highest prevalence of H. pylori, while camel (5.00%) had the lowest. H. pylori strains harbored the highest prevalence of resistance against ampicillin (82.08%), tetracycline (76.11%), amoxicillin (74.62%), metronidazole (65.67%) and erythromycin (53.73%). Prevalence of resistance against more than 10 types of antibiotics was 17.91%. VacA s1a (83.58%), m1a (80.59%), s2 (77.61%) and m2 (68.65%), cagA (73.13%) and babA2 (44.77%) were the most commonly detected genotypes. We found that S1am1a (56.71%), s2m1a (56.71%), s1 am2 (43.28%) and s2 m2 (43.28%) were the most commonly detected genotyping pattern. Frequency of cagA-, oipA- and babA2- genotypes were 26.86%, 62.68% and 55.22%, respectively. We found that S1a/cagA+/iceA1/oipA-/babA2- (28.35%), m1a/cagA+/iceA1/oipA-/babA2- (28.35%) and s2/cagA+/iceA1/oipA-/babA2- (26.86%) were the most commonly detected combined genotyping pattern. Conclusions: Simultaneous presence of vacA, cagA, iceA, oipA and babA2 genotypes in antibiotic resistant H. pylori strains indicates important public health issue regarding the consumption of raw milk. However, additional researches are required to find molecular genetic homology and other epidemiological aspects of H. pylori in milk. PMID- 30288256 TI - Factors associated with bacteraemia due to multidrug-resistant organisms among bacteraemic patients with multidrug-resistant organism carriage: a case control study. AB - Background: Infections caused by multidrug-resistant organisms (MDRO) are emerging worldwide. Physicians are increasingly faced with the question of whether patients need empiric antibiotic treatment covering these pathogens. This question is especially essential among MDRO carriers. We aim to determine the occurrence of MDRO bacteraemia among bacteraemic patients colonized with MDRO, and the associated factors with MDRO bacteraemia among this population. Methods: We performed a retrospective monocentric study among MDRO carriers hospitalized with bacteraemia between January 2013 and August 2016 in a French hospital. We compared characteristics of patients with MDRO and non-MDRO bacteraemia. Results: Overall, 368 episodes of bacteraemia were reviewed; 98/368 (26.6%) occurred among MDRO carriers.Main colonizing bacteria were extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (40/98; 40.8%), ESBL-producing Klebsiella pneumoniae (35/98; 35.7%); methicillin-resistant Staphylococcus aureus (26/98; 26.5%) and multidrug-resistant Pseudomonas aeruginosa (PA) (12/98; 12.2%).There was no significant difference considering population with MDRO bacteraemia vs. non-MDRO bacteraemia, except for immunosuppression [OR 2.86; p = 0.0207], severity of the episode [OR 3.13; p = 0.0232], carriage of PA [OR 5.24; p = 0.0395], and hospital-acquired infection [OR 2.49; p = 0.034].In the multivariate analysis, factors significantly associated with MDRO bacteraemia among colonized patient were only immunosuppression [OR = 2.96; p = 0.0354] and the hospital acquired origin of bacteraemia [OR = 2.62; p = 0.0427]. Conclusions: According to our study, occurrence of bacteraemia due to MDRO among MDRO carriers was high. Factors associated with MDRO bacteraemia were severity of the episode and hospital-acquired origin of the bacteraemia. Thus, during bacteraemia among patients colonized with MDRO, if such characteristics are present, broad-spectrum antimicrobial treatment is recommended. PMID- 30288258 TI - Why do people choose nephrology? Identifying positive motivators to aid recruitment and retention. AB - Increasing concerns about recruitment and retention of junior doctors have led to renewed interest in how and when trainees choose their specialties. To our knowledge, no study has yet reported what attracts UK applicants to nephrology nor how clinicians develop vocational interests or make occupational choices. With this in mind, we sought to explore the motivation behind current nephrologist's career choices in the UK. We interviewed 11 nephrologists using a semi-structured face-to-face approach and used interpretative phenomenological analysis to conduct and analyse the interviews. We found role models were pivotal in encouraging specialization in nephrology, particularly those encountered in early postgraduate training. The diversity, diagnostic challenge and cross specialty knowledge was highlighted as well as the ability to 'make a difference to patients' lives'. Nephrologists enjoyed the challenge of managing very sick, acutely unwell patients as well as the holistic continuity of long-term care offered to dialysis patients and their families. Academic and procedural components were attractive motivators to the specialty and the flexibility to have multiple interests was noted, with many nephrologists having 'portfolio' careers. Based on these results, we suggest strategies the specialty can use to aid policy decision making, promote recruitment and improve educational experiences within current training programmes. PMID- 30288257 TI - Send more data: a systematic review of mathematical models of antimicrobial resistance. AB - Background: Antimicrobial resistance is a global health problem that demands all possible means to control it. Mathematical modelling is a valuable tool for understanding the mechanisms of AMR development and spread, and can help us to investigate and propose novel control strategies. However, it is of vital importance that mathematical models have a broad utility, which can be assured if good modelling practice is followed. Objective: The objective of this study was to provide a comprehensive systematic review of published models of AMR development and spread. Furthermore, the study aimed to identify gaps in the knowledge required to develop useful models. Methods: The review comprised a comprehensive literature search with 38 selected studies. Information was extracted from the selected papers using an adaptation of previously published frameworks, and was evaluated using the TRACE good modelling practice guidelines. Results: None of the selected papers fulfilled the TRACE guidelines. We recommend that future mathematical models should: a) model the biological processes mechanistically, b) incorporate uncertainty and variability in the system using stochastic modelling, c) include a sensitivity analysis and model external and internal validation. Conclusion: Many mathematical models of AMR development and spread exist. There is still a lack of knowledge about antimicrobial resistance, which restricts the development of useful mathematical models. PMID- 30288260 TI - Acute kidney injury in children with nephrotic syndrome: a single-center study. AB - Background: Children with nephrotic syndrome (NS) are at risk for the development of acute kidney injury (AKI) through a variety of mechanisms.The frequency of NS hospitalizations complicated by AKI has almost doubled in the last decade. Children with AKI have longer hospital length of stay and increased need for intensive care unit admission. The main objectives of this study were to determine the incidence, clinical characteristics, risk factors and short-term outcome of AKI in children hospitalized with NS. Methods: In this retrospective study, 355 children <=18 years of age with a clinical diagnosis of NS admitted in the Department of Nephrology, Gauhati Medical College and Hospital from January 2012 to December 2015 were reviewed. Results: The incidence of AKI in children with NS was found to be 23.66%, 11.24%, 7.95% and 4.48% of children entered Pediatric Risk, Injury, Failure, Loss, End-Stage Renal Disease (pRIFLE) Stages R, I and F, respectively. Infection {odds ratio [OR] 2.53 [95% confidence interval (CI) 1.52-4.22]} and nephrotoxic medication exposure [OR 7.8 (95% CI 4.06-15.01)] were common factors associated with AKI. Children with steroid-dependent NS (SDNS) and steroid-resistant NS (SRNS) were more likely to develop AKI compared with children with steroid-sensitive NS (SSNS). The mean time to recovery for groups pRIFLE Stages R, I and F were 15 +/- 2 , 22 +/- 3 and 28 +/- 5 days, respectively. Children with NS who were hypertensive, had higher urinary protein excretion and low serum albumin were more prone to develop AKI. Conclusions: AKI is not uncommon in children with NS. Infection and exposure to nephrotoxic drugs are common factors associated with AKI. AKI is more frequent in SDNS and SRNS compared with SSNS. The mean time to recovery is prolonged with more severe AKI. PMID- 30288259 TI - Haemodynamic or metabolic stimulation tests to reveal the renal functional response: requiem or revival? AB - Renal stimulation tests document the dynamic response of the glomerular filtration rate (GFR) after a single or a combination of stimuli, such as an intravenous infusion of dopamine or amino acids or an oral protein meal. The increment of the GFR above the unstimulated state has formerly been called the renal functional reserve (RFR). Although the concept of a renal reserve capacity has not withstood scientific scrutiny, the literature documenting renal stimulation merits renewed interest. An absent or a blunted response of the GFR after a stimulus indicates lost or diseased nephrons. This information is valuable in preventing, diagnosing and prognosticating acute kidney injury and pregnancy-related renal events as well as chronic kidney disease. However, before renal function testing is universally practiced, some shortcomings must be addressed. First, a common nomenclature should be decided upon. The expression of RFR should be replaced by renal functional response. Second, a simple protocol must be developed and propagated. Third, we suggest designing prospective studies linking a defective stimulatory response to emergence of renal injury biomarkers, to histological or morphological renal abnormalities and to adverse renal outcomes in different renal syndromes. PMID- 30288262 TI - Severe tubulointerstitial nephritis: tracking tuberculosis even in the absence of renal granuloma. AB - Extra-pulmonary tuberculosis is frequently located in the kidneys and, in such cases, could be associated with a granulomatous interstitial nephritis. Granulomas are not always detected, especially in human immunodeficiency virus (HIV)-positive patients. We report here a case of tubulointerstitial nephritis without granulomas in an HIV-negative patient. Since all laboratory tests failed to isolate Mycobacterium tuberculosis in the kidney, a targeted biopsy guided by positron emission tomography-computed tomography was performed on a mediastinal node, revealing a positive culture. After 6 months of treatment, no recovery of the renal injury has been observed. PMID- 30288261 TI - De novo antineutrophil cytoplasmic antibody-associated vasculitis in pregnancy: a systematic review on maternal, pregnancy and fetal outcomes. AB - Background: De novo antineutrophil cytoplasmic antibody-associated vasculitis typically arises in post-reproductive years, but can occur during pregnancy. Concerns of treatment-related teratogenicity persist, while efficacy and safety of new therapies including intravenous immunoglobulin (IVIG) and rituximab are uncertain. There remains a paucity of maternal, fetal and pregnancy outcome data in these women, and therefore a lack of guidance on safe treatment for clinicians. Methods: We conducted a systematic review of the literature and a local, retrospective chart review of women with de novo antibody-associated vasculitis (AAV) in pregnancy. Cochrane, Embase and PubMed databases and relevant conference abstracts were searched. Patient demographics, clinical presentation, management and outcomes (maternal, fetal and pregnancy-related) were analyzed. Results: Twenty-seven cases of de novo AAV in pregnancy were included. Women presented were from 5 to 39 weeks' gestation, of which a majority were in the second trimester (median 20 weeks). The median gravida of women was 2 and the median parity was 1. Women were treated with steroids (89%), cyclophosphamide (CYC) (37%), other immunosuppressive agents [azathioprine (AZA), IVIG, plasma exchange (PLEX)] or no therapy (11%). High rates of serious complications, including preeclampsia (29%) and maternal death (7%), were reported; however, most pregnancies resulted in live birth (73%). Prematurity was common; 73% of live births occurred prior to 37 weeks' gestation and 40% prior to 34 weeks' gestation. The majority of infants were born in the third trimester (median 34.5 weeks). Rates of pregnancy termination were high (23%) and only one intrauterine death was reported, shortly after initiation of therapy (4%). Congenital abnormalities were rare, with one infant having a solitary, pelvic kidney (6%) after maternal treatment with steroids, CYC and PLEX. Use of PLEX, IVIG and AZA increased after 2005, whereas CYC use decreased. Remission often occurred postpartum (60%). Conclusions: De novo AAV in pregnancy can result in uncomplicated pregnancies; however, serious maternal risks exist. Further data on potentially pregnancy compatible therapies such as IVIG and rituximab are needed in this population. PMID- 30288263 TI - Renal involvement in chronic lymphocytic leukemia. AB - Chronic lymphocytic leukemia (CLL) is the most commonly diagnosed adult leukemia in the USA and Western Europe. Kidney disease can present in patients with CLL as a manifestation of the disease process such as acute kidney injury with infiltration or with a paraneoplastic glomerular disease or as a manifestation of extra renal obstruction and tumor lysis syndrome. In the current era of novel targeted therapies, kidney disease can also present as a complication of treatment. Tumor lysis syndrome associated with novel agents such as the B-cell lymphoma 2 inhibitor venetoclax and the monoclonal antibody obinutuzumab are important nephrotoxicities associated with these agents. Here we review the various forms of kidney diseases associated with CLL and its therapies. PMID- 30288264 TI - Is renal tubular cadmium toxicity clinically relevant? AB - Background: Exposure to cadmium (Cd) has been associated with the development of hypertension, especially in women, but the mechanism of such an association is not understood. We hypothesize that Cd exposure alters renal production of 20 hydroxyeicosatetraenoic acid (20-HETE), which plays an indispensable role in renal salt balance and blood pressure control. Methods: We examined long-term Cd exposure in relation to urinary 20-HETE excretion levels, tubular dysfunction and blood pressure measures, using data from a population-based, cross-sectional study that included 115 normotensive and 110 hypertensive women, 33-55 years of age, who lived in Cd contamination areas in Thailand. Results: The mean [standard deviation (SD)] blood Cd level of the study subjects was 3.57 (3.3) ug/L, while the mean (SD) urinary Cd and urinary 20-HETE levels were 0.58 (0.47) ug/g creatinine and 1651 (4793) pg/mL, respectively. Elevated 20-HETE levels were associated with a 90% increase in prevalence odds of hypertension (P = 0.029), four times greater odds of having higher urinary Cd levels (P = 0.030) and a 53% increase in odds of having higher levels of tubular dysfunction (P = 0.049), evident from an increase in urinary excretion of beta2-microglobulin. In normotensive subjects, an increase in urinary 20-HETE levels from tertile 1 to tertile 3 was associated with a systolic blood pressure increase of 6 mmHg (95% confidence interval 0.3-12, P = 0.040). Conclusions: This is the first report that links urinary 20-HETE levels to blood pressure increases in Cd-exposed women, thereby providing a plausible mechanism for associated development of hypertension. PMID- 30288266 TI - Multi-intervention management of calcific uremic arteriolopathy in 24 patients. AB - Background: Calcific uremic arteriolopathy (CUA), also known as calciphylaxis, is a rare but life-threatening condition predominately occurring in patients with end-stage renal disease on dialysis. In the absence of randomized clinical trials to guide management, clinicians must rely on observational data. We have previously reported the outcomes of our multi-intervention management in seven patients and now present a larger series of patients with extended follow-up. Methods: We performed a retrospective analysis of all patients diagnosed with CUA at a single academic center between 2008 and 2017. We identified 24 patients including 13 hemodialysis, 8 peritoneal dialysis and 3 predialysis Stage 5 chronic kidney disease patients. Results: Mean age at diagnosis was 60.5 years (range 35-83) and mean follow-up 30.5 months (range <1-99). Patients were predominately female (71%) and Caucasian (83%) with diabetes mellitus diagnosed in 16 of 24 patients. Fifteen of 24 patients had ulcerating lesions suggestive of advanced disease and 20 of 24 had extensive involvement (bilateral disease or lesion size >5 cm). Treatment consisted of intensive hemodialysis (>20 h per week), sodium thiosulfate, wound care, analgesics and discontinuation of trigger medications including warfarin. Hyperbaric oxygen, cinacalcet, bisphosphonates and vitamin K were used in some cases. Overall 1 year mortality was 41% (9/22) and overall mortality at the end of follow-up was 64% (14/24). Cause of death was felt to be attributable to CUA in only four cases (16.7%). Complete or partial resolution of lesions occurred in 17 of 24 patients. One patient had recurrence of CUA 20 months after initial diagnosis. Conclusions: Although mortality remains high in this group, direct CUA-attributable mortality is lower than historic reports. We conclude that a multi-intervention approach can be successful in treating a group of patients with severe CUA lesions. PMID- 30288265 TI - The metabolomic quest for a biomarker in chronic kidney disease. AB - Chronic kidney disease (CKD) is a growing burden on people and on healthcare for which the diagnostics are niether disease-specific nor indicative of progression. Biomarkers are sought to enable clinicians to offer more appropriate patient centred treatments, which could come to fruition by using a metabolomics approach. This mini-review highlights the current literature of metabolomics and CKD, and suggests additional factors that need to be considered in this quest for a biomarker, namely the diet and the gut microbiome, for more meaningful advances to be made. PMID- 30288267 TI - Achievement of 2009 and 2017 Kidney Disease: Improving Global Outcomes mineral and bone targets and survival in a French cohort of chronic kidney disease Stages 4 and 5 non-dialysis patients. AB - Background: The aim of the third French Phosphorus and Calcium Observatory (Photo Graphe(r) 3) was to assess the achievement of international Kidney Disease: Improving Global Outcomes (KDIGO) recommendations on optimal serum phosphate, calcium and parathyroid hormone (PTH) levels and possible associations with mortality in patients with chronic kidney disease (CKD). Methods: This was a prospective, observational study conducted with nephrologists in France who were selected using a clustering approach. Adult patients with non-dialysis Stage 4 or 5 CKD and no kidney graft history were eligible. Data about clinical events, serum biochemistry and treatment were collected every 6 months for 2.5 years and 12 months thereafter. The Kaplan-Meier method was used for survival analysis and Cox proportional hazards model for identification of factors associated with survival. Results: Overall, 566 CKD Stage 4 patients (men, 56%) and 153 CKD Stage 5 patients (men, 62%) were included. In Stage 4, only 14-15% patients achieved the three main 2009 KDIGO targets during the first 2 years and 22% at 2.5 years. In Stage 5 patients, the proportion remained <6% throughout. The percentages of patients achieving the three main 2017 KDIGO targets were slightly higher at each time point. Overall, 14% of Stage 4 and 10% of Stage 5 patients died in the observation period. Only age and haemoglobin level were significantly associated with risk of all-cause mortality. Conclusions: Few CKD patients achieved KDIGO mineral targets. Increased mortality risk was linked to older age and lower haemoglobin level, but not to serum calcium, phosphate or PTH targets. PMID- 30288268 TI - Using manual exchanges for an urgent-start peritoneal dialysis program. AB - Background: Urgent-start peritoneal dialysis (USPD) was designed to avoid temporary hemodialysis initiation with a hemodialysis catheter. In these patients, PD is initiated within 2 weeks of catheter placement, but typically these prescriptions utilize automated peritoneal dialysis (APD) with a cycler. Manual exchanges have not been reported previously for USPD. We hypothesize that using multiple, low-volume manual exchanges, patients will have similar rates of peritonitis, exit-site infection (ESI), pericatheter leaks and discontinuation of PD in the first 3 months after initiation. Methods: This retrospective study included patients who initiated PD in our unit from May 2014 until August 2016 using our USPD protocol. Patients with a body surface area <1.7 m2 used 750 mL dwell volumes and those >1.7 m2 used 1000 mL dwell volumes during the first 7 days. Dwell times were 2-2.5 h for two to three exchanges per day. After 7 days of successful therapy, the dwell volumes were doubled. All patients were maintained on furosemide 160 mg twice daily. Results: There were 20 patients enrolled in our USPD program. Our rates of peritonitis, ESI, pericatheter leak and discontinuation of PD were 5%, 0%, 5% and 5%, respectively. Conclusions: Manual exchange during USPD is a viable modality with similar results as APD. Using manual exchanges allows patients to be more ambulatory during the day when they are not dwelling, allows nurses to evaluate the amount of ultrafiltration and effluent characteristics and allows for training in manual exchanges as well. PMID- 30288269 TI - Peritoneal dialysis catheter leakage following intermittent vacuum therapy. AB - Peripheral arterial disease and diabetic foot syndrome are common comorbidities in dialysis patients. These conditions are treated with intermittent vacuum therapy in order to increase angiogenesis and perfusion. Some devices encase the lower extremities up to the abdomen. Here we report the case of a patient who had performed peritoneal dialysis for 2 years without complications. Following postoperative intermittent vacuum therapy, he presented with extensive catheter leakage. Ultimately the patient had to be switched to haemodialysis and the catheter had to be removed. This case exemplifies that peritoneal dialysis patients have a substantial risk for noninfectious catheter-related complications using vacuum therapy. PMID- 30288271 TI - Correlation between Dt/V derived from ionic dialysance and blood-driven Kt/V of urea in African-American hemodialysis patients, based on body weight and ultrafiltration volume. AB - Background: The Dt/V obtained by using ionic dialysance (D) as a surrogate for urea clearance (K) is a well-validated adjunct measure of hemodialysis adequacy, with a variable level of correlation with urea-based Kt/V. However, this correlation has not been examined based on patients' body size and ultrafiltration (UF) volume during the dialysis session. Methods: Simultaneous evaluations of online Dt/V and single-pool variable-volume urea Kt/V were made. Patients were categorized into three subgroups based on their weight (<60, 60-80 and >=80 kg), body mass index (<25, 25-30 and >30 kg/m2) and UF volume (<1.5, 1.5 3 and >3 L). The correlation between Dt/V and Kt/V was evaluated for the entire cohort per dialysis session in each subgroup. Results: Mean Kt/V was greater than the mean Dt/V (1.72 versus 1.50, P < 0.001), with an overall correlation r value of 0.602. This correlation was stronger in the medium weight group versus lower and higher weights. The correlation between Dt/V and Kt/V was inversely related to the UF volume (r = 0.698, 0.621 and 0.558 for those with UF volume of <1.5, 1.5-3.0 and >3 L, respectively). A total of 99.3% of patients with Dt/V of >1.2 also had Kt/V >1.2 and 9.5% of those with Dt/V <1.2 had their Kt/V <1.2. Conclusions: There is a moderate degree of correlation between Dt/V and Kt/V in African-American hemodialysis patients, which is impacted by body size and UF volume. A Dt/V of >1.2 strongly predicts adequate dialysis as defined by Kt/V of >1.2. PMID- 30288270 TI - Cost of hemodialysis in a public sector tertiary hospital of India. AB - Introduction: Nearly 220000 patients are diagnosed with end-stage renal disease (ESRD) every year, which calls for an additional demand of 34 million dialysis sessions in India. The government of India has announced a National Dialysis Programme to provide for free dialysis in public hospitals. In this article we estimate the overall cost of performing hemodialysis (HD) in a tertiary care hospital. Second, we assess the catastrophic impact of out-of-pocket expenditures (OOPEs) for HD on households and its determinants. Methods: The economic health system cost of HD was estimated using bottom-up costing methods. All resources, capital and recurrent, utilized for service delivery from April 2015 to March 2016 were identified, measured and valued. Capital costs were annualized after accounting for their useful life and discounting at 3% for future years. Sensitivity analyses were undertaken to determine the effect of variation in the input prices and other assumptions on the annual health system cost. OOPEs were assessed by interviewing 108 patients undergoing HD in the study hospital to account for costs from the patient's perspective. The prevalence of catastrophic health expenditures (CHEs) was computed per threshold of 40% of non-food expenditures. Results: The overall average cost incurred by the health system per HD session was INR 4148 (US$64). Adjusting for capacity utilization, the health system incurred INR 3025 (US$47) per HD at 100% bed occupancy. The mean OOPE per patient per session was INR 2838 (US$44; 95% confidence interval US$34-55). The major components of this OOPE were medicines and consumables (64.1%). The prevalence of a CHE per HD session was 11.1%. Conclusion: Our study findings would be useful in the context of planning for dialysis services, setting provider payment rates for dialysis under various publicly sponsored health insurance schemes and undertaking future cost-effectiveness analysis to guide resource allocation decisions. PMID- 30288272 TI - Evaluation of the efficacy of a medium cut-off dialyser and comparison with other high-flux dialysers in conventional haemodialysis and online haemodiafiltration. AB - Background: Online haemodiafiltration (OL-HDF) has been shown to reduce all-cause mortality versus conventional haemodialysis (HD); however, it is not always available. In these situations, a novel class of membranes with a higher pore size, medium cut-off (MCO) dialysers, could be promising. The aim of this study is to evaluate the efficacy of an MCO dialyser in the removal of small and medium size molecules and compare it with standard high-flux (HF) dialysers in HD and OL HDF. Methods: In this crossover study, 18 prevalent HD patients were studied in three single mid-week dialysis treatments during three consecutive weeks as follows: first week with OL-HDF with a standard HF dialyser, second week with conventional HD with a standard HF dialyser and third week with conventional HD with an MCO dialyser. Reduction ratios (RRs) of different-sized molecules and albumin losses were collected for the different dialysers. Results: MCO HD provided a greater reduction of middle and larger middle molecules compared with standard HF HD [rate reduction (RR) beta2-microglobulin 74.7% versus 69.7%, P=0.01; RR myoglobin 62.5% versus 34.3%, P=0.001; RR prolactin 60% versus 32.8%, P=0.001; RR alpha1-glycoprotein 2.8% versus -0.1%, P=0.01]. We found no difference in the clearance of small and larger middle molecules comparing MCO HD with OL-HDF. Albumin losses were 0.03 g/session with MCO HD and 3.1 g/session with OL-HDF (P=0.001). Conclusion: MCO HD is superior to standard HF HD in the removal of middle and larger middle molecules and it is not inferior to OL-HDF in the clearance of small and larger middle molecules. Thus it could be an alternative in patients in which it is not possible to perform OL-HDF. PMID- 30288273 TI - Expert opinion for use of faecal calprotectin in diagnosis and monitoring of inflammatory bowel disease in daily clinical practice. AB - Background: Despite many publications regarding the role of faecal calprotectin (FC) in inflammatory bowel disease (IBD), clear recommendations for its use in clinical practice are currently lacking in the literature. Aim: The aim of this article is to provide practical guidance for clinicians for the use of FC in the detection and management of patients with IBD. Methods: All relevant publications were analysed and practical statements were proposed based on a Delphi consensus approach. Results: Different commercial assays have been developed but international standardisation is lacking. FC can help in the diagnosis process of IBD. In IBD, FC can predict response to therapy, detect subclinical inflammation and help to drive treatment decisions to achieve better endoscopic and clinical outcomes. After Crohn's surgery FC can identify patients with early endoscopic recurrence. Conclusion: Although major therapeutic changes should not be based on FC alone, FC is a valuable tool to optimise the care for IBD patients. PMID- 30288274 TI - New developments in the treatment of opioid-induced gastrointestinal symptoms. AB - Chronic pain affects a large part of the global population, leading to an increase of opioid use. Opioid-induced constipation (OIC), a highly prevalent adverse effect of opioid use, has a major impact on patients' quality of life. Thanks to the introduction of new drugs for chronic constipation, which can also be used in OIC, and the development of peripherally acting mu-opioid receptor blockers, specifically for use in OIC, therapeutic options have seen major development. This review summarises current and emerging treatment options for OIC based on an extensive bibliographical search. Efficacy data for laxatives, lubiprostone, prucalopride, linaclotide, oxycodone/naloxone combinations, methylnaltrexone, alvimopan, naloxegol, naldemedine, axelopran, and bevenopran in OIC are summarised. PMID- 30288275 TI - Diabetes is an independent risk factor for delayed perforation after foreign bodies impacted in esophagus in adults. AB - Background: Perforation is the most serious complication of esophageal foreign bodies. Studies examining the association between diabetes and esophageal foreign body-induced perforation are largely non-existent. Objectives: The purpose of this study was to identify the risk factors for esophageal foreign body-induced perforation. Methods: A retrospective chart review of patients with esophageal foreign bodies between January 2012-January 2017 was performed at the Chinese People's Liberation Army General Hospital. The patients were divided into two groups: those complicated with perforation and those without perforation. Date on patient demographics, symptoms, foreign bodies, and diabetes were collected and analyzed. Study-specific odds ratio and 95% confidence intervals (CI) were estimated using multivariable logistic regression models. Results: Of 294 patients with esophageal foreign bodies (41.84% male, mean age, 56.73 years), 33 (11.22%) complicated by perforation. Diabetes (odds ratio = 6.00; 95% confidence interval = 1.72-20.23), duration (>24 h) of foreign bodies retention (odds ratio = 4.25; 95% confidence interval = 1.71-10.86), and preoperative fever (odds ratio = 8.19; 95% confidence interval = 3.17-21.74) were strongly associated with an increased risk of perforation, whereas the sensation of a foreign body (odds ratio = 0.32; 95% confidence interval = 0.09-0.92) was a protective factor of perforation. Glucose level was not observed to have an association among patients with or without perforation. Conclusions: Diabetes and duration of foreign body retention increase risk for esophageal foreign bodies complicated by perforation, and cases with elevated armpit temperature may represented a more likely perforation compared with those without fever. PMID- 30288276 TI - Physical activity, sedentary behaviour and risk of oesophago-gastric cancer: A prospective cohort study within UK Biobank. AB - Background: Few observational studies have assessed the role of physical activity in oesophago-gastric cancer risk. Objective: This prospective cohort study aimed to assess the association between physical activity and risk of oesophageal or gastric cancer. Methods: A cohort of 359,033 adults aged 40-69 years were identified from the UK Biobank, which recruited participants between 2006 and 2010. Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the associations between self-reported levels of physical activity and screen-based sedentary behaviour and risk of oesophageal and gastric cancer were calculated using Cox proportional hazards models. Results: During eight years of follow-up (mean = 5.5), 294 oesophageal cancer and 217 gastric cancer cases were identified. Physical activity and screen-based sedentary behaviour levels were not associated with overall oesophago-gastric cancer risk. However, when compared with low levels, high physical activity levels were associated with a significantly reduced risk of gastric non-cardia cancer (HR 0.58, 95% CI 0.37 0.95). Moderate physical activity levels were associated with a 38% reduced risk of oesophageal adenocarcinoma (HR 0.62, 95% CI 0.43-0.89), although no dose response association was apparent. Conclusion: Moderate, rather than high, physical activity levels were associated with the strongest reductions in oesophageal adenocarcinoma risk in this large UK prospective cohort. PMID- 30288277 TI - Nitrous oxide cryotherapy ablation for refractory gastric antral vascular ectasia. AB - Background: Argon plasma coagulation (APC) is typically the first-line therapy for gastric antral vascular ectasia (GAVE). However, many patients are refractory to APC ablation. Objective: We examined the safety and efficacy of nitrous oxide CryoBalloon cryotherapy ablation for GAVE refractory to APC. Methods: This is a retrospective review of patients with refractory GAVE treated with the CryoBalloon system. Technical success was defined as successful ablation of the visualized GAVE. Clinical success was defined by transfusion independence and percentage of GAVE that was eradicated. Results: Twenty-three patients with GAVE were included, of whom 16 patients (70%) had two treatments with the CryoBalloon and seven patients (30%) had one treatment. Technical success was achieved in all patients. At six months, 19/23 (83%) were transfusion independent, while 20/23 (87%) had more than 75% of the GAVE eradicated. Patients were transfused an average of 1.8 units/month one year prior to cryotherapy and an average of 0.3 units/month up to six months post-cryotherapy (p < 0.001). The average increase in mean hemoglobin at six months was 2.55 g/dl. No acute or late adverse events were reported. Conclusions: CryoBalloon ablation is an efficacious and safe modality for the treatment of GAVE. Prospective studies need to be conducted to determine comparative results to standard therapies. PMID- 30288278 TI - Risk factors associated with osteoporosis in a cohort of prospectively diagnosed adult coeliac patients. AB - Background: Up to 75% of patients with untreated coeliac disease (CD) present with osteopenia or osteoporosis. Guidelines do not express with certainty whether each patient with newly diagnosed CD should undergo a dual-energy x-ray absorptiometry (DEXA) scan. Aim: The aim of this article is to evaluate the prevalence of bone mineral density (BMD) alterations at diagnosis and risk factors associated with osteoporosis. Methods: A total of 214 adult patients (median age 38 years; female = 71.5%) newly diagnosed with CD underwent DEXA. The patients were divided into three groups: patients with normal BMD, those with osteopenia and those with osteoporosis. Clinical, histological and serological features were assessed and compared among the three groups. Logistic regression including relevant independent variables was performed. Results: DEXA indicated that 39.7%, 42.5% and 17.8% of the CD patients had normal BMD, osteopenia and osteoporosis, respectively. Logistic regression indicated that features significantly associated with osteoporosis were male gender (OR 4.7; 95%CI 1.1 to 20.8), age >=45 years (OR 6.5; 95% CI 1.3 to 32.2), underweight (OR 7.4; 95% CI 1.3 to 42.5) and greater histological damage (Marsh 3C; OR 5.8; 95% CI 1.4 to 24.1). Conclusions: BMD alterations were found in 60.3% of newly diagnosed adult coeliac patients. Osteoporosis was significantly associated with age >=45 years, male gender, underweight and Marsh 3C, suggesting that at CD diagnosis, a DEXA scan might be beneficial, particularly in these subgroups of patients. PMID- 30288279 TI - The etiology of potential small-bowel bleeding depending on patient's age and gender. AB - Background: Whether the etiology of potential small-bowel bleeding depends on the age and gender of the patient is not yet fully understood. Methods: A total of 1953 patients who underwent video capsule endoscopy (VCE) to evaluate potential small-bowel bleeding and were registered in the Capsule Endoscopy Nationwide Database Registry from 2003 to 2014 were eligible for this study. VCE findings and the etiology of small-bowel bleeding were analyzed by age and gender. Results: The diagnostic yield of VCE was 48.4% (95% CI: 46.2%-50.6%) and the diagnosis rate of etiology of potential small-bowel bleeding was 61.4% (95% CI: 59.2%-63.6%). The etiology of potential small-bowel bleeding depends on the age and gender of the patient. Crohn's disease and small-bowel diverticular diseases were more prevalent etiology of potential small-bowel bleeding in the young adults group (< 40 years) whereas angiodysplasia was revealed to be a most common etiology in elderly group (>= 60 years), reaching statistical significance (p<0.00152) by Bonferroni correction. Conclusions: The etiology of potential small-bowel bleeding depends on the age of the patient. Thus, an individualized lesion-specific diagnostic approach based on age might be needed for patients with potential small-bowel bleeding. PMID- 30288280 TI - Association of proton pump inhibitors with the risk of hepatic encephalopathy during hospitalization for liver cirrhosis. AB - Background: Hepatic encephalopathy is associated with altered gut microbiota. Proton pump inhibitors increase the risk of small bowel bacterial overgrowth. Objectives: This was a case-control study aimed at exploring the relationship of proton pump inhibitor use with the risk of hepatic encephalopathy during hospitalization in liver cirrhosis. Methods: Case and control groups were defined as cirrhotic patients who developed hepatic encephalopathy during hospitalization and those without hepatic encephalopathy at admission or during hospitalization, respectively. Age, gender, and Child-Pugh score were matched between the groups. Odds ratios with 95% confidence intervals were calculated to express the association of proton pump inhibitors with the risk of hepatic encephalopathy. Four subgroup analyses were performed after excluding patients with acute upper gastrointestinal bleeding, infections, and in-hospital death, and after matching model for end-stage liver disease score. Results: In the overall analysis, 128 patients were included in each group of cases and controls. The proportion of proton pump inhibitor use was significantly higher in the case group than the control group (79.7% vs 43%, p < 0.001). Proton pump inhibitor use (odds ratio = 3.481, 95% confidence interval: 1.651-7.340, p = 0.001) was independently associated with the development of hepatic encephalopathy in the multivariate analysis. In the four subgroup analyses, proton pump inhibitor use remained independently associated with the risk of hepatic encephalopathy. Conclusion: Proton pump inhibitor use might increase the risk of hepatic encephalopathy during hospitalization. PMID- 30288282 TI - Terlipressin for variceal bleeding induces large plasma sodium fluctuations in patients without cirrhosis. AB - Background: Terlipressin is used as pharmacological treatment for variceal bleeding. The drug's physiological effect favours hyponatremia, and rapid changes in plasma sodium (PNa) may cause brain injury. Cirrhosis patients seem to be largely protected against this effect but patients without cirrhosis may not be so. Objective: The objective of this study was to examine whether terlipressin treatment of patients without cirrhosis leads to more serious fluctuations in PNa than in cirrhosis. Methods: In a retrospective cohort design, during a 39-month period, 11 patients with prehepatic portal hypertension and no cirrhosis and 134 patients with cirrhosis received a minimum cumulative terlipressin dose of 4 mg during at least 24 hours for variceal bleeding. The groups' PNa changes were compared. Results: During terlipressin, the non-cirrhotic patients developed a greater reduction in PNa [mean 8.3 (95% confidence interval (CI) 1.9-14.6) vs. 1.8 (1.0-2.7) mmol/l; p = 0.048], a lower nadir PNa [129 (123-135) vs. 133 (132 134) mmol/l; p = 0.06], and within 48 hours after terlipressin a greater increase in PNa [12.6 (3.4-21.7) vs. 2.3 (1.5-3.0) mmol/l; p = 0.03]. Severe (>10 mmol/l change) hyponatriemia or PNa rebound were seen in 27% of these patients but in only 4% of those with cirrhosis (p = 0.02). One non-cirrhotic patient developed permanent brain damage. Conclusion: Terlipressin treatment of bleeding varices carries a high risk of potentially dangerous PNa fluctuations in patients with non-cirrhotic prehepatic portal hypertension. PMID- 30288281 TI - Long-term changes in liver elasticity in hepatitis C virus-infected patients with sustained virologic response after treatment with direct-acting antivirals. AB - Background: The use of interferon-free direct-acting antiviral agents (DAAs) is associated with a rapid short-term decrease in liver stiffness in chronic hepatitis C-infected patients with sustained virologic response (SVR). Objective: The objective of this article is to evaluate long-term changes in liver elasticity in hepatitis C patients with SVR using transient elastography (TE), FIB-4 and APRI. Methods: A total of 143 patients were treated with DAAs and reached SVR. Patients received TE measurement (median (range)) at treatment start (baseline), follow-up week 24 (FU24) and follow-up week 96 (FU96). Laboratory data were examined at each date and FIB-4 and APRI were calculated. Results: Liver elasticity showed a significant decrease from baseline to FU24 (13.1 (3.1 75) kPa to 9.3 (2.9-69.1) kPa; p < 0.0001) and declined further until FU96 (7.9 (2.4-59.3) kPa; p < 0.0001). Liver inflammation and liver function parameters normalised during long-term follow-up. Progression of liver stiffness between FU24 to FU96 despite viral clearance was observed in 24 patients (17%). Long-term liver stiffness progression was associated with aspartate aminotransferase levels and TE change from baseline to FU24. Conclusion: During long-term follow-up, the majority of patients with SVR had further improved liver stiffness values. Still, a significant proportion of patients may show long-term liver stiffness progression and thus continued TE follow-up is recommended. PMID- 30288283 TI - Statin use is not associated with an increased risk of acute pancreatitis-A meta analysis of observational studies. AB - Background: Statins are perceived as potential etiological factors for acute pancreatitis (AP), but recent evidence suggests the opposite. Our aim was to evaluate the association between statin use and risk of AP in observational studies. Methods: Medline, Scopus, and Web of Science were searched for cohort (C) and case-control (CC) studies evaluating statins as intervention and AP as outcome. Pooled adjusted odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were calculated. Results: Thirteen studies (seven CC, six C) with 34,899 AP patients and 5,377,894 controls were included. Prevalence of statin use was 9.8% among AP patients and 25% among controls. Pooled adjusted OR was 1.00 (95% CI = 0.63 to 1.59) with considerable heterogeneity (I 2 = 98%). CC studies were associated with increased AP risk (OR = 1.33; 95% CI = 1.20 to 1.47), unlike C studies (OR = 0.69; 95% CI = 0.37 to 1.31). No association with increased risk was found for studies from Western countries (OR = 0.90; 95% CI = 0.52 to 1.56), unlike for studies conducted in Asia (OR = 1.39; 95% CI = 1.10 to 1.75). Conclusion: Statin use is not associated with increased risk of AP. Increased risk was limited to CC studies, which are more prone to bias, while C studies showed no global effect. Further research is needed to clarify whether statin type, dosage, treatment duration or AP etiology might account for this difference. PMID- 30288284 TI - Features of incident colorectal cancer in Lynch syndrome. AB - Background and objective: Despite intensive colonoscopic surveillance, a substantial proportion of Lynch syndrome (LS) patients develop colorectal cancer (CRC). The aim of this study was to characterize incident CRC in LS patients. Methods: All patients diagnosed with incident CRC after start of colonoscopic surveillance were identified in the Dutch LS Registry of 905 patients. A retrospective analysis of patient records was carried out for patient characteristics, survival, CRC characteristics and findings of previous colonoscopy. Results: Seventy-one patients (7.8%) were diagnosed with incident CRC. Median interval between incident CRC diagnosis and previous colonoscopy was 23.8 (range 6.7-45.6) months. Median tumor diameter was 2.5 cm, and 17% of the tumors were sessile or flat. Most patients (83%) had no lymph node metastases. There was no association between tumor size and colonoscopy interval or lymph node status. Most patients (65%) had no adenomas during previous colonoscopy. Two patients (2.8%) eventually died from metastatic CRC. Conclusion: The high frequency of incident CRC in LS likely results from several factors. Our findings lend support to the hypothesis of fast conversion of adenomas to CRC, as 65% of patients had no report of polyps during previous colonoscopy. High-quality colonoscopies are essential, especially as tumors and adenomas are difficult to detect because of their frequent non-polypoid appearance. Early detection due to surveillance as well as the indolent growth of CRC, as demonstrated by the lack of lymph node metastases, contributes to the excellent survival observed. PMID- 30288285 TI - Fecal immunochemical test for hemoglobin in combination with fecal transferrin in colorectal cancer screening. AB - Objective: Fecal transferrin has been suggested as a complementary or even superior marker for early detection of colorectal cancer (CRC) besides fecal hemoglobin. We aimed to evaluate both markers individually and in combination in a large cohort of participants of screening colonoscopy. Methods: Precolonoscopy stool samples were obtained from participants of screening colonoscopy and frozen at -80C until blinded analysis, using a dual-quantitative fecal immunochemical test (FIT) for hemoglobin and transferrin. Sensitivity, specificity and area under the curve (AUC) were calculated for CRC and advanced adenoma (AA). Results: A total of 1667 participants fulfilled our inclusion criteria. All individuals with advanced neoplasm (AN) (16 CRC, 200 AA) and 300 randomly selected participants without AN were included. Mean age was 63 years and 56% were male. The AUC for CRC and AA was 92% and 68%, respectively, for hemoglobin vs. 79% and 58%, respectively for transferrin. Combination of both markers yielded an AUC for CRC and AA of 92% and 68%, respectively. Conclusion: FIT for hemoglobin shows better diagnostic performance than FIT for transferrin for the detection of ANs (both proximal and distal neoplasms), and a combination of both markers does not improve the diagnostic performance. PMID- 30288286 TI - Efficacy of different faecal microbiota transplantation protocols for Clostridium difficile infection: A systematic review and meta-analysis. AB - Background: Protocols for treating recurrent Clostridium difficile infection (rCDI) through faecal microbiota transplantation (FMT) are still not standardised. Our aim was to evaluate the efficacy of different FMT protocols for rCDI according to routes, number of infusions and infused material. Methods: MEDLINE, Embase, SCOPUS, Web of Science and the Cochrane Library were searched through 31 May 2017. Studies offering multiple infusions if a single infusion failed to cure rCDI were included. Data were combined through a random effects meta-analysis. Results: Fifteen studies (1150 subjects) were analysed. Multiple infusions increased efficacy rates overall (76% versus 93%) and in each route of delivery (duodenal delivery: 73% with single infusion versus 81% with multiple infusions; capsule: 80% versus 92%; colonoscopy: 78% versus 98% and enema: 56% versus 92%). Duodenal delivery and colonoscopy were associated, respectively, with lower efficacy rates (p = 0.039) and higher efficacy rates (p = 0.006) overall. Faecal amount <= 50 g (p = 0.006) and enema (p = 0.019) were associated with lower efficacy rates after a single infusion. The use of fresh or frozen faeces did not influence outcomes. Conclusions: Routes, number of infusions and faecal dosage may influence efficacy rates of FMT for rCDI. These findings could help to optimise FMT protocols in clinical practice. PMID- 30288287 TI - Post-infectious IBS: Defining its clinical features and prognosis using an internet-based survey. AB - Background: Gastrointestinal infection is an important risk factor for developing irritable bowel syndrome (IBS). Our aim was to characterise post-infectious IBS (PI-IBS) compared to other IBS patients. Methods: An internet survey of IBS patients using Rome III diagnostic questionnaire, Hospital Anxiety and Depression Scale (HADS) and Patient Health Questionnaire-12 Somatic Symptom (PHQ12-SS) scale score documenting the mode of onset was conducted. Results: A total of 7811 participants (63.2% female), of whom 1004 (13.3%) met criteria for PI-IBS, were studied. Seventy per cent of PI-IBS patients described sudden onset, 35% onset while travelling, 49.6% vomiting, 49.9% fever and 20.3% bloody diarrhoea. Compared to other IBS individuals, PI-IBS was significantly associated with living in Northern Europe and North America, having a hysterectomy, not having an appendicectomy, higher PHQ12-SS score and having more than one toilet in the family home. PI-IBS patients had more frequent stools. At one year recovery rate in the PI-IBS and non-PI-IBS group was 19.7% and 22.2%, p = 0.15. Recovery rates were lower for females (20.7%) vs males (38.8%), those with somatisation (23.0%) vs those without (33.2%) and those living in North America or Northern Europe (21.1%) vs living elsewhere (33.9%) p <= 0.001. Conclusion: PI-IBS accounts for around 13% of all IBS in this internet sample, with some distinctive features but a similar prognosis to the remainder. PMID- 30288288 TI - The patient burden of opioid-induced constipation: New insights from a large, multinational survey in five European countries. AB - Background: Despite its high prevalence, opioid-induced constipation (OIC) remains under-recognised and undertreated, and its true impact on wellbeing and quality of life (QoL) may be underestimated. Methods: A quantitative, questionnaire-based international survey was conducted. Results: Weak-opioid users appeared as bothered by constipation as strong-opioid users (38% vs 40%, respectively; p = 0.40), despite it causing less-severe physical symptoms and impact on QoL. Strong-opioid users meeting Rome IV OIC criteria appeared to experience greater symptomatic and biopsychosocial burden from constipation than those not satisfying these criteria. Almost one-fifth of respondents were dissatisfied with their current constipation treatment and around one-third found balancing the need for adequate pain relief with constipation side effects challenging. Consequently, more than half failed to adhere to their prescribed treatment regimens, or resorted to suboptimal strategies, e.g. 40% reduced their opioid intake, to relieve constipation. Almost 60% of healthcare professionals did not adequately counsel patients about constipation as a common side effect of opioid use. Conclusions: Findings suggest that both weak- and strong-opioid users suffer comparable bother and decreased QoL, Rome IV criteria can identify patients with more-severe OIC, but may underdiagnose patients showing fewer symptoms, and increased education is needed to manage patients' expectations and enable improved OIC self-management.

PMID- 30288289 TI - Contribution of genetic amplification by PCR for the diagnosis of Helicobacter pylori infection in patients receiving proton pump inhibitors. AB - Background: Helicobacter pylori detection by standard methods may be altered by proton pump inhibitor (PPI) use. However, some patients cannot or should not interrupt PPI use before undergoing testing for H. pylori. Polymerase chain reaction (PCR) could allow more reliable H. pylori detection even in patients taking PPIs. Objective: The aim of our study is to compare the H. pylori infection diagnostic value of histological examination without and with immunohistochemical staining, bacterial culture and PCR, in PPI-treated vs untreated patients. Methods: Patients undergoing a gastric endoscopy for upper digestive symptoms were included. Gastric biopsy samples were obtained. The impact of taking PPI on the diagnostic performance of the different methods was studied. PCR results were confirmed by sequencing the glmM gene. Results: A total of 497 patients were included, of whom 192 were H. pylori positive. Fifty-two patients received PPIs during the 14 days preceding the endoscopy while 140 did not. All methods had lower sensitivity than PCR, in all cases (PPI treatment or not). PPI use did not change significantly the methods' sensitivities. Conclusion: The PCR method showed the best performance for the detection of H. pylori in gastric samples, whether or not patients received previous PPI treatment. This diagnosis test could become a new gold-standard test, especially in patients undergoing PPI treatment.

PMID- 30288293 TI - A new anthropometric index for body fat estimation in patients with severe obesity. AB - Background: Body mass index (BMI) has been used to assess body adiposity, but it cannot adequately reflect body fat (BF) amount. The body adiposity index (BAI) has been shown a better performance than BMI for this purpose, but it can be inaccurate to estimate BF under extreme amounts of fat. Here, we propose a new anthropometric index, the Belarmino-Waitzberg (BeW) index, for specific estimation of BF in severely obese patients. Methods: In 144 adult patients with severe obesity, BF was estimated by air displacement plethysmography (ADP), as the reference method, along with the follow anthropometric measurements: height, abdominal circumference (AC), hip circumference (HC), weight, BMI (weight/ height2) and BAI ([HC(cm) / height (m)1.5) - 18] * 100). Patients were proportionately distributed into two distinct databases, the building model database (BMD) and the validation model database (VMD), which were applied to develop and validate the BeW index, respectively. The BeW index was tested for gender and ethnicity adjustment as independent variables. The agreement of BF% values obtained by the new index and by BAI with ADP was also assessed. Results: The BF% was 52.05 +/- 5.42 for ADP and 59.11 +/- 5.95 for the BeW index (all results are expressed as the mean +/- standard deviation). A positive Pearson correlation (r = 0.74), a good accuracy (Cb = 0.94), and a positive Lin's concordance correlation (CCC = 0.70) were observed between the two groups. The 95% limits of individual agreement between the BeW index and ADP were 6.8 to 7.9%, compared to - 7.5 to 14.8% between the BAI and ADP. The new index, called the Belarmino-Waitzberg (BeW) index, showed an improvement of 2.1% for the R2 value and a significant gender effect, therefore resulting in two different indexes for females and males, as follows: Female BeW = - 48.8 + 0.087 * AC(cm) + 1.147 * HC(cm) - 0.003 * HC(cm)2 and Male BeW = - 48.8 + 0.087 * AC(cm) + 1.147 * HC(cm) - 0.003 * HC(cm)2-7.195. Conclusions: The new BeW index showed a good performance for BF estimation in patients with severe obesity and can be superior to the BAI for this purpose. PMID- 30288294 TI - Are There Differences in Workplace Accommodation Needs, Use and Unmet Needs Among Older Workers With Arthritis, Diabetes and No Chronic Conditions? Examining the Role of Health and Work Context. AB - The aging of workforces combined with the prevalence of age-related chronic diseases has generated interest in whether large numbers of older workers will need workplace accommodations. This research applied work functioning theory to examine accommodation availability, need and use in workers with arthritis, diabetes, or no chronic disabling diseases; factors associated with accommodation needs; and the relationship of accommodation needs met, unmet or exceeded to job outcomes. Participants were aged 50-67 years, employed, and had arthritis (n = 631), diabetes (n = 286), both arthritis/diabetes (n = 111) or no chronic disabling conditions (healthy controls n = 538). They were recruited from a national panel of 80,000 individuals and a cross-sectional survey was administered online or by telephone. Questionnaires assessed demographics, health, work context, workplace accommodations, and job outcomes. Chi-square analyses, analyses of variance, and regression analyses compared groups. Respondents were similar in many demographic and work context factors. As expected, workers with arthritis and/or diabetes often reported poorer health and employment outcomes. Yet, there were few differences across health conditions in need for or use of accommodations with most participants reporting accommodations needs met. In keeping with work functioning theory, unmet accommodation needs were largely related to work context, not health. Workers whose accommodation needs were exceeded reported better job outcomes than those with accommodation needs met. Findings highlight both work context and health in understanding workplace accommodations and suggest that many older workers can meet accommodation needs with existing workplace practices. However, additional research aimed at workplace support and the timing of accommodation use is needed. PMID- 30288295 TI - Risk factors for venous irritation in patients receiving vinorelbine: a retrospective study. AB - Background: Vinorelbine is known to be effective in the treatment of non-small cell lung cancer and breast cancer. However, venous irritation is a common side effect. Although there have been some reports on risk factors for venous irritation in patients receiving vinorelbine, the factors evaluated have been limited and the results inconclusive. The aim of this study was to identify risk factors for venous irritation in patients receiving vinorelbine, and factors likely associated with venous irritation, including new factors such as hot compress with a hot towel for prevention of venous irritation. Methods: We retrospectively reviewed patients treated with vinorelbine at Kyorin University Hospital, Japan, between March 2013 and December 2016 and divided them into the two groups according to whether or not they had venous irritation. Clinical characteristics were compared between the two groups. Results: Venous irritation occurred in 24 (38.1%) of 63 patients who received vinorelbine. The median number of times vinorelbine was administered before onset of venous irritation was 3 (range 1-14). The group with venous irritation had a significantly lower body surface area than the group without venous irritation (p = 0.035). Low body surface area was also the only significant risk factor for vinorelbine-associated venous irritation in multivariate analysis (adjusted odds ratio 70.42 per 1 m2decrement, 95% confidence interval 1.54-3236.25, p = 0.029). There was no association between the occurrence of venous irritation and the other covariates, such as use of a hot compress, history of diabetes mellitus, or use of a generic formulation of vinorelbine. Conclusion: Low body surface area may be a risk factor for venous irritation in patients receiving vinorelbine. Use of hot compress with a hot towel did not prevent venous irritation. PMID- 30288296 TI - Start-up financing of professional pest control in pig farming in North Rhine Westphalia in Germany. AB - Background: Due to the risk of spreading epizootic diseases through rodents, pest control is mandatory in pig farming in European countries. However, there is limited research focused on rodent control practices, usage of anticoagulant rodenticides, and the acceptance of Pest Control Operators (PCOs) in pig farming in Germany. Therefore, the present study aims to investigate current control practices in pig holdings and to analyze the potential of a financial support on the implementation of professional pest control. Results: Data were collected from monitoring records of PCOs and personal interviews with farmers and PCOs. 33 of 47 farmers, who were offered the possibility to outsource rodent control to PCOs supported by financial contribution of the North Rhine-Westphalian Animal Disease Fund (TSK) for a period of 2 years, joined the project.Despite the widespread opinion that the professional would not be beneficial - the authors figured out that farmers could financially benefit in time saved and by improved rodent control measures from the work of the PCOs. Costs of pest control measures per operation on average did not differ significantly between costs incurred by employment of PCOs (1.310 ? per year) and calculated costs that arise by farmers themselves (1.217 ? per year).All PCOs used Difenacoum and Brodifacoum against pest infestations. In doing so, the infestation with rodents was reduced and most of the participating farmers assessed the project as successful and employ the PCOs permanently. However, mapping the farm locations to resistance areas of the Rodenticide Resistance Action Committee (RRAC) shows that Brodifacoum was frequently used in areas which are marked as areas that are at low risk or rather have no risk for resistance. The environmental risks, however, are increased in these areas. Conclusion: The instrument of temporal start-up financing professional pest control allows ensuring the continuous engagement of PCOs after the project period. This could possibly lead to long-term effects on the individual farm hygiene and on disease prevention. Nevertheless, important research questions with regard to the application of anticoagulant rodenticides of farmers and PCOs in livestock farming and with regard to risk mitigation measures were generated, meriting further investigation. PMID- 30288297 TI - Korea hypertension fact sheet 2018. AB - Background: The Korea Hypertension Fact Sheet 2018 aims to overview the magnitude and management status of hypertension, and their trends in Korea. Methods: The Hypertension Epidemiology Research Group analyzed the 1998-2016 Korea National Health and Nutrition Examination Survey data and the 2002-2016 Korea National Health Insurance Big Data. Results: The population average of systolic/diastolic blood pressure was 118/77 mmHg among Korean adults (age 30+) in 2016, showing little change in recent 10 years. However, the number of people with hypertension increased steadily, exceeding 11 million. The number of people diagnosed with hypertension increased from 3 million in 2002 to 8.9 million in 2016. The number of people using antihypertensive medication increased from 2.5 million in 2002 to 8.2 million in 2016. However, only 5.7 million people are being treated constantly. Hypertension awareness, treatment, and control rates increased fast until 2007, but showed a plateau thereafter. More than half of the young hypertensive patients (30-49 years) did not know about and treat for their hypertension. Among patients prescribed antihypertensive medications, 45% was elderly people over the age of 65 years, 57% used anti-diabetic or cholesterol lowering medications, and 60% were prescribed two or more class of antihypertensive medications simultaneously. Conclusions: In Korea, the level of hypertension management has considerably improved over the last 20 years. In order to achieve further improvement in hypertension management status, we need to find the vulnerable subgroups and develop subgroup-specific intervention strategies. It is also becoming more important to manage hypertensive patients at older age and those with concurrent chronic diseases. PMID- 30288298 TI - How to engage patients in research and quality improvement in community-based primary care settings: protocol for a participatory action research pilot study. AB - Plain English summary: Making primary care clinics more patient-centered is key to improving patients' experience of care. If patients themselves were engaged in helping define priorities and suggesting quality improvements in the clinic, care would respond better to their needs. However, patient engagement is a new phenomenon, particularly in community based primary care clinics. How to engage patients in quality improvement in these clinics, or what effect this might have, is not well known. The involvement of patients needs to be adapted to the way these clinics function. The aim of this study is to create and evaluate a new model of patient engagement for quality improvement in community based primary care clinics. Patients, primary care professionals and researchers will create advisory councils in two primary care clinics in Quebec City (Canada). In each clinic, the advisory council will include 12 patients or caregivers registered at the clinic, a clinician and a clinic manager. The advisory council will meet every 6 weeks for a total of six meetings. Two patient-experts will facilitate meetings. During meetings, members of the council will list their needs in order of importance. Then they will suggest improvements in line with these needs. We will study if our advisory council model is well adapted to community based primary care settings and meets participants' expectations. At the end of the study we will be able to offer guidance about engaging patients with health professionals in quality improvement in primary care clinics. Abstract: Background Involvement of end-users, including patients, managers and clinicians, in identifying quality improvement and research priorities might improve the relevance of projects and increase their impact. Few patient engagement initiatives have taken place in community based primary care practices (CBPCPs) and best practices for engaging patients in such settings are not well defined. The aim of this pilot study is to develop and assess the feasibility of a new collaborative model of advisory council involving clinicians, managers, patients and caregivers in CBPCP to strengthen their capacity to conduct quality improvement and patient-oriented research projects. Methods We will conduct a participatory action research project in two non-academic CBPCPs in Quebec City (Canada). In each CBPCP, the advisory council will include 12 patients or caregivers, a clinician and a clinic manager. Patients or their caregivers will be identified by clinicians and contacted by patient-experts. They will be eligible if they are registered at the practice, motivated, and available to attend meetings. The council will meet every 6 weeks for a total of six meetings. Two patient-experts will guide council members to identify quality improvement priorities and patient-oriented research questions based on their experience in the clinic. They will then be supported to plan actions to target these priorities. Analysis of meetings will be based on feasibility criteria, notes by non-participant observers in log books, audio-recording of the meetings and questionnaires to evaluate council members' perceptions and the likelihood they would engage in such councils. Discussion The results of this study will be a model of patient engagement and a discussion of factors to improve the model to fit the needs of primary care patients and professionals. This will lay the foundation for a sustainable structure for long-term patient engagement and contribute to the development of a patient-centered and quality-improvement culture in CBPCPs.

AB - Intrathoracic endometriosis is classified into pleurodiaphragmatic endometriosis and bronchopulmonary endometriosis. Bronchopulmonary endometriosis is rare. Computed tomography (CT) findings of bronchopulmonary endometriosis are lung nodules, with or without cavities, or surrounding ground-glass opacities. Features vary with menstrual status. Recently, the usefulness of magnetic resonance imaging (MRI) was reported for diagnosis of intrathoracic endometriosis, but most published reports were about pleurodiaphragmatic endometriosis. We present CT and MRI findings of bronchopulmonary endometriosis in the left lung that showed a gradually enlarging nodule with enhancing area. PMID- 30288300 TI - Beneficial coinfection can promote within-host viral diversity. AB - In many viral infections, a large number of different genetic variants can coexist within a host, leading to more virulent infections that are better able to evolve antiviral resistance and adapt to new hosts. But how is this diversity maintained? Why do faster-growing variants not outcompete slower-growing variants, and erode this diversity? One hypothesis is if there are mutually beneficial interactions between variants, with host cells infected by multiple different viral genomes producing more, or more effective, virions. We modelled this hypothesis with both mathematical models and simulations, and found that moderate levels of beneficial coinfection can maintain high levels of coexistence, even when coinfection is relatively rare, and when there are significant fitness differences between competing variants. Rare variants are more likely to be coinfecting with a different variant, and hence beneficial coinfection increases the relative fitness of rare variants through negative frequency dependence, and maintains diversity. We further find that coexisting variants sometimes reach unequal frequencies, depending on the extent to which different variants benefit from coinfection, and the ratio of variants which leads to the most productive infected cells. These factors could help drive the evolution of defective interfering particles, and help to explain why the different segments of multipartite viruses persist at different equilibrium frequencies. PMID- 30288299 TI - Islands of linkage in an ocean of pervasive recombination reveals two-speed evolution of human cytomegalovirus genomes. AB - Human cytomegalovirus (HCMV) infects most of the population worldwide, persisting throughout the host's life in a latent state with periodic episodes of reactivation. While typically asymptomatic, HCMV can cause fatal disease among congenitally infected infants and immunocompromised patients. These clinical issues are compounded by the emergence of antiviral resistance and the absence of an effective vaccine, the development of which is likely complicated by the numerous immune evasins encoded by HCMV to counter the host's adaptive immune responses, a feature that facilitates frequent super-infections. Understanding the evolutionary dynamics of HCMV is essential for the development of effective new drugs and vaccines. By comparing viral genomes from uncultivated or low passaged clinical samples of diverse origins, we observe evidence of frequent homologous recombination events, both recent and ancient, and no structure of HCMV genetic diversity at the whole-genome scale. Analysis of individual gene scale loci reveals a striking dichotomy: while most of the genome is highly conserved, recombines essentially freely and has evolved under purifying selection, 21 genes display extreme diversity, structured into distinct genotypes that do not recombine with each other. Most of these hyper-variable genes encode glycoproteins involved in cell entry or escape of host immunity. Evidence that half of them have diverged through episodes of intense positive selection suggests that rapid evolution of hyper-variable loci is likely driven by interactions with host immunity. It appears that this process is enabled by recombination unlinking hyper-variable loci from strongly constrained neighboring sites. It is conceivable that viral mechanisms facilitating super-infection have evolved to promote recombination between diverged genotypes, allowing the virus to continuously diversify at key loci to escape immune detection, while maintaining a genome optimally adapted to its asymptomatic infectious lifecycle.

AB - Hepatology, Medicine and Policy (HMAP), a new open-access peer-reviewed journal, is making its debut at a time when the hepatitis field is seeing great progress but still has far to go. The World Health Organization and many countries have shown increasing interest in viral hepatitis in recent years, helping to foster a stronger response to this group of diseases. Meanwhile, alcohol-associated cirrhosis and alcohol-associated liver cancer continue to take a heavy toll worldwide, as does non-alcoholic fatty liver disease. The lack of a unified strategic response to viral hepatitis and other liver diseases is the impetus for launching HMAP, which will publish policy, public health and social science articles alongside clinical science articles. It will encourage submissions in diverse domains such as disease prevention and management, epidemiology, economics, health behavior, health service delivery, ethics, human rights, and the role of laws, policies and clinical guidelines in shaping health initiatives. The current attention to powerful new hepatitis C treatments presents a strategic opportunity to more comprehensively address the full constellation of biomedical and social issues relating to liver health. HMAP is committed to publishing research and policy articles that help to drive forward this broader agenda. PMID- 30288303 TI - Predisposing, enabling, and need factors associated with utilization of HCV testing services among PWID in two settings in India. AB - Background: The Hepatitis C virus (HCV) is very common among people who inject drugs (PWID), yet PWID in India have suboptimal access to HCV testing and treatment. This study sought to identify HCV risk factors among male PWID who utilized a free needle and syringe exchange program and to examine the predisposing, enabling, and need factors associated with utilization of HCV testing services by those PWID reporting that they had been tested. Methods: A cross-sectional study was conducted in Imphal, Manipur and Amritsar, Punjab. These two settings have high HCV prevalence and large numbers of PWID. A team of 18 field investigators obtained data through face-to-face interviews using a structured multiple-choice questionnaire. The questionnaire was administered to 1241 of 2644 male PWID aged 15 years and above enrolled in the needle and syringe program of India's AIDS Control Program, with study participants selected through consecutive sampling. Statistical analyses included descriptive statistics and multivariate regression. Results: Twenty-four percent of PWID in our study sample reported having been tested for HCV. Unlike PWID in Imphal, more than half of PWID in Amritsar reported unprotected sex and use of alcohol or non-injecting drugs as being among their HCV risk factors (67.1 and 77.8 %, respectively). However, opioid substitution therapy non-adherence was reported more often in Imphal than in Amritsar. Education, marital status, place of residence and duration of injecting drug use were found to significantly enable access to HCV testing while alcohol use, frequent mobility and unprotected sex were found to significantly inhibit access to HCV testing for PWID after controlling for other explanatory variables. Conclusions: Predisposing and enabling determinants provide an area for developing effective interventions to improve HCV testing practices among PWID. HCV prevention programs that address safe injecting and sexual practices, OST adherence and frequent mobility customized for PWID by age are strongly recommended. PMID- 30288304 TI - A new paradigm evaluating cost per cure of HCV infection in the UK. AB - Background: New interferon (IFN)-free treatments for hepatitis C are more effective, safer but more expensive than current IFN-based therapies. Comparative data of these, versus current first generation protease inhibitors (PI) with regard to costs and treatment outcomes are needed. We investigated the real-world effectiveness, safety and cost per cure of 1st generation PI-based therapies in the UK. Methods: Medical records review of patients within the HCV Research UK database. Patients had received treatment with telaprevir or boceprevir and pegylated interferon and ribavirin (PR). Data on treatment outcome, healthcare utilisation and adverse events (AEs) requiring intervention were collected and analysed overall and by subgroups. Costs of visits, tests, therapies, adverse events and hospitalisations were estimated at the patient level. Total cost per cure was calculated as total median cost divided by SVR rate. Results: 154 patients from 35 centres were analysed. Overall median total cost per cure was L44,852 (subgroup range,: L35,492 to L107,288). Total treatment costs were accounted for by PI: 68.3 %, PR: 26.3 %, AE management: 5.4 %. Overall SVR was 62.3 % (range 25 % to 86.2 %). 36 % of patients experienced treatment-related AEs requiring intervention, 10 % required treatment-related hospitalisation. Conclusions: This is the first UK multicentre study of outcomes and costs of PI based HCV treatments in clinical practice. There was substantial variation in total cost per cure among patient subgroups and high rates of treatment-related discontinuations, AEs and hospitalisations. Real world safety, effectiveness and total cost per cure for the new IFN free combinations should be compared against this baseline. PMID- 30288305 TI - Urgent action to fight hepatitis C in people who inject drugs in Europe. AB - Hepatitis C virus (HCV) infection is a leading cause of liver cirrhosis and liver cancer, is curable in most people. Injecting drug use currently accounts for 80 % of new HCV infections with a known transmission route in the European Union (EU). HCV has generally received little attention from the public or policymakers in the EU, with major gaps in national-level strategies, action plans, guidelines and the evidence base. Specifically, people who inject drugs (PWID) are often excluded from treatment owing to various patient, healthcare provider and health system factors. All policymakers responsible for health services in EU countries should ensure that prevention, treatment, care and support interventions addressing HCV in PWID are developed and implemented. According to current best practice, PWID should have access to comprehensive, evidence-based multiprofessional harm reduction (especially opioid substitution therapy and clean needles and syringes) and support/care services based in the community and modified with community involvement to accommodate this hard-to-reach population. Other recommended components of care include vaccination against hepatitis B and other infections; peer support interventions; HIV testing, prevention and treatment; drug and alcohol services; psychological care as needed; and social support services. HCV testing should be performed regularly in PWID to identify infected persons and engage them in care. HCV-infected PWID should be considered for antiviral treatment (based on an individualised assessment and delivered within multidisciplinary care/support programmes) both to cure infected individuals and prevent onward transmission. Modelling data suggest that the HCV disease burden can only be cut substantially if antiviral treatment is scaled up together with prevention programmes. Measures should be taken to reduce stigma and discrimination against PWID at the provider and institutional levels. In conclusion, strategic action at the policy level is urgently needed to increase access to HCV prevention, testing and treatment among PWID, the group at highest risk of HCV infection. Such action has the potential to substantially reduce the number of infected persons, along with the disease burden and related care costs. PMID- 30288306 TI - State of viral hepatitis knowledge and testing uptake in Brazil: Findings from the National Survey of Knowledge, Attitudes and Practices (PCAP-2013). AB - Background: Data were obtained from the third National Survey of Knowledge, Attitudes and Practices of HIV and other Sexually Transmitted Infections (STI) (PCAP-2013) and used to describe the current state of viral hepatitis (VH) knowledge and screening as well as the prevalence of viral hepatitis B (HBV) vaccination in Brazil and to assess the factors associated with testing uptake. Methods: A probability sample survey of 12,000 individuals (50 % men) aged between 15 and 64 years was conducted between October and December of 2013. The participants completed the survey in their own homes through computer-assisted face-to-face interviews and self-interviews. We analysed data related to self reported knowledge of VH routes and screening uptake after weighting the variables to account for unequal selection probabilities and correct for differences in sex, age and region according to 2010 census figures. Results: The levels of correct knowledge regarding HBV and HCV transmission through unprotected sex were 33.1 and 34.3 %, respectively. The levels of correct knowledge regarding HBV and HCV transmission through tattooing/piercing were 26.4 and 24.5 %, respectively. Overall, 29 % of the respondents reported having underwent VH screening and 73.9 % reported prior HBV vaccination. VH screening was associated with the following factors: age between 25 and 49 years (adjusted male odds ratio (OR): 2.29, [95 % confidence interval (CI): 1.83-2.87]; female OR: 1.36, [95 % CI: 1.10-1.67]); age between 50 and 64 years (male OR: 1.52, [CI: 1.13-2.03]; female OR: 1.29, [CI: 1.02-1.63]); initial sexual intercourse before the age of 15 years in men (OR: 1.32, [CI: 1.10-1.57]); higher socioeconomic statuses of group A (male OR: 2.38, [CI: 1.81-3.13]; female OR: 2.10, [CI: 1.66 2.68]) and B (female OR: 1.56, [CI: 1.27-1.93]); and having ever been tested for HIV (male OR: 7.50, [CI: 5.82-8.53]; female OR: 7.13, [CI: 5.97-8.54]). Conclusions: This study revealed low levels of knowledge regarding VH transmission and screening practices in the general Brazilian population, especially among younger individuals and those with lower socioeconomic status. Efforts to enhance awareness campaigns and expand testing sites are needed to remove barriers to testing. PMID- 30288307 TI - Strengthening hepatitis B and C surveillance in Europe: results from the two global hepatitis policy surveys (2013 and 2014). AB - Background: Hepatitis B and C are major public health threats in the World Health Organization (WHO) European Region. Viral hepatitis surveillance shortcomings have resulted in many WHO Member States having insufficient data available to guide decision-making. This study describes surveillance in the region based on a quantitative sub-analysis of findings from the 2013 WHO viral hepatitis policy report and a qualitative analysis of civil society survey responses associated with these findings. Methods: Descriptive statistics were created from information that national government focal points for viral hepatitis in 44 countries had previously reported in response to the WHO survey. Bivariate analysis was performed to compare data from within and outside of the European Union/European Economic Area (EU/EEA). Survey responses from civil society organizations in the countries of the WHO European Region were collated, and a descriptive analysis of the comments on surveillance-related questions was performed to identify key themes. Results: The response rate for the survey of governments was 83 % among both EU/EEA countries (25/30) and non-EU/EEA countries (19/23). More than 90 % of governments reported having national surveillance systems for the acute forms of hepatitis B and hepatitis C, but less than two thirds reported surveillance for the chronic forms of both diseases. High proportions of governments reported having central registries for the reporting of deaths (96 %) and liver cancer cases (80 %), while less than half reported regularly conducting viral hepatitis sero-surveys. All responding Member States reported having adequate laboratory capacity nationally to support hepatitis outbreak investigations and other surveillance activities. Target populations for sero-surveys most commonly included people who inject drugs (27 %), the general population (25 %), men who have sex with men (20 %) and pregnant women (20 %). Few statistically significant differences were found between EU/EEA and non EU/EEA countries. Conclusions: Study findings indicated a capacity for robust viral hepatitis surveillance across the WHO European Region, with most countries having important surveillance components in place, but notable weaknesses were also identified. There is an urgent need for countries throughout the region to strengthen their surveillance programs in order to maximize the population-level impact of advances in HBV and HCV prevention and treatment. PMID- 30288308 TI - Hepatitis B knowledge among key stakeholders in Haimen City, China: Implications for addressing chronic HBV infection. AB - Background: This article describes hepatitis B-related knowledge, attitudes and practices after completion of the Gateway to Care campaign, a citywide public health education program that targeted city residents, health care providers and individuals chronically infected with hepatitis B virus in Haimen City, China. Methods: Pre/post questionnaires assessed hepatitis B knowledge change among health care providers and post-campaign surveys evaluated hepatitis B knowledge, attitudes and behaviors (including stigma-related beliefs and practices) among health care providers, city residents and chronically infected individuals. Focus groups were conducted to gain a more in-depth understanding of the needs of the target communities, and to identify future intervention strategies to improve hepatitis B testing and linkage to care and treatment. Results: Results indicate high levels of hepatitis B knowledge among multiple stakeholders in Haimen City, with significant knowledge improvement among health care providers. Stigma related beliefs and myths regarding separation of infected individuals from certain aspects of family life were common among all stakeholder groups, despite high levels of accurate knowledge about hepatitis B transmission and prevention. Self-report of hepatitis B screening was low among city residents, as was awareness of hepatitis B treatment. Conclusions: More efforts are needed to improve awareness of HBV treatment, decrease HBV-related stigma, improve screening rates, and reduce cost of antiviral treatment. Future interventions in Haimen City should be driven by behavioral change theory, to not only improve knowledge, but to improve screening behaviors and address hepatitis B-related stigma and discrimination. PMID- 30288309 TI - Hepatitis B knowledge among women of childbearing age in three slums in Mumbai: a cross-sectional survey. AB - Background: More than 17 million people in India are chronically infected with the hepatitis B virus (HBV). Approximately one million of the 26 million children born in India annually will develop chronic HBV infection in the course of their lives. Studies have put the HBsAg prevalence rate among pregnant women in India between 0.9 % and 3.1, indicating a considerable need for public health interventions aimed at protecting their offspring from infection. The PAHAL project in Mumbai, India, conducted an HBV knowledge survey among women of childbearing age in three local slum communities preparatory to planning a comprehensive HBV education intervention targeting this population. Methods: Female health workers approached all households in three designated slum neighborhoods: one each in the eastern suburbs (ES), western suburbs (WS) and Island City (IC). Female residents aged 18-45 were invited to participate in the study, and those who agreed to participate responded to a questionnaire that was administered in the form of an oral interview. The five sections of the questionnaire addressed demography, hepatitis B knowledge, personal risk related to hepatitis B, pregnancy and childbearing history, and the participant's most recent pregnancy. A descriptive statistical analysis was performed. Results: Health workers submitted 6571 interview forms that were suitable for analysis (ES, 28 %; WS, 34 %; IC, 38 %). Large proportions of study participants were married (89 %), were not employed (94 %) and had completed less than 12 years of school (87 %). Only 240 (3.6 %) women answered yes when asked if they knew about hepatitis B. Among those women, there were high levels of accurate knowledge regarding some modes of hepatitis B transmission but low levels of accurate knowledge regarding other modes. Twenty-two percent of 739 women who had given birth within the previous 36 months reported that they had been tested for HBV during pregnancy. While 70 % of these women reported that their children had received three doses of hepatitis B vaccine, reported vaccination levels varied greatly across the three study areas. Conclusions: Despite the availability of a safe HBV vaccine, which is free for newborns and infants in many parts of India, preventing mother-to-child transmission of HBV remains a major challenge. Low awareness of HBV among women of childbearing age in Mumbai-area slums indicates a need for educational interventions targeting this population. PMID- 30288310 TI - A community- based hepatitis B linkage-to-care program: a case study on Asian Americans chronically infected with hepatitis B virus. AB - Background: Hepatitis B is an important disease of ethnic disparity which affects Asian Americans and other minority populations disproportionately. Despite the high prevalence of hepatitis B in Asian Americans, many of them remain unscreened and untreated. A majority of the individuals chronically infected with hepatitis B virus (HBV) are not linked to care, for instance, due to a lack of culturally competent programs. There are many serious barriers preventing linkage to care (LTC), including personal, socio-cultural, and economic issues. The purpose of this study was to evaluate various barriers affecting LTC and to investigate the role and efficacy of a community-based Patient Navigator (PN) program in expediting LTC and in improving health outcomes for hepatitis B patients in a high risk population. Methods: A total of 45 individuals chronically infected with HBV were identified through community screening events and were subsequently linked to patient navigators (PN), who then arranged for the patients to have a medical evaluation with a provider of their choice in their communities. The navigators kept detailed records of the patients' progress towards goal, and planned follow up visits for each patient. A self-report questionnaire was employed to assess patients' demographics, history of HBV infection, and barriers in accessing health care. Specifically, the levels of importance of the barriers due to language, culture, financial reasons were assessed. Results: The study revealed that 38 of the 45 HBV infected individuals knew about their infection status from previous screening. Forty two out of 45 HBV infected individuals were linked to care within a 12 month period, demonstrating a high linkage rate. Most significant barriers identified were language and finance, followed by cultural barrier and others. Conclusion: There are specific barriers to accessing adequate care for the patients affected by chronic hepatitis B (CHB) in Korean American community. The implementation of a PN program in conjunction with the community network of health care providers may help to overcome the barriers and facilitate LTC in hepatitis B. PMID- 30288311 TI - Coverage of different health insurance programs and medical costs associated with chronic hepatitis C infection in mainland China: a cross-sectional survey in 20 provinces. AB - Background: Hepatitis C virus (HCV) imposes a considerable disease burden in China, with at least 10 million people chronically infected. Little is known about the financial impact of the HCV epidemic, nor about the extent to which various forms of insurance are providing HCV patients with financial protection. A cross-sectional multi-site study was conducted to acquire data that will aid policy-makers and other stakeholders in developing effective strategies to address this situation. Methods: At 29 hospitals across China, inpatients and outpatients with chronic HCV were surveyed about their insurance coverage and medical costs. Percentages, means and medians were calculated, and differences in continuous variables among multiple groups were analyzed using the Kruskal-Wallis test or Wilcoxon two-sample test. Results: Many inpatients (N = 593) and outpatients (N = 523) reported being covered by one of three major types of government health insurance, but 13 % of inpatients and 43 % of outpatients reported having no insurance. Among inpatients, the total median cost per hospitalization per patient was 8212 Renminbi (RMB). The category of expenditure with the highest median cost per hospitalization was Western medicine, followed by lab tests and Chinese medicine. The median cost per hospitalization was far higher for patients who had hepatocellular carcinoma than for those with less severe forms of liver disease. Outpatient antiviral therapy costs ranged from a median of 377 RMB for ribavirin to a median of 37,400 RMB for pegylated interferon-alpha for up to one year of treatment. Conclusions: For uninsured chronic HCV patients in China, inpatient and outpatient costs may be financially devastating. Research is needed on how different approaches to financing HCV treatment and care might improve health outcomes as well as achieve cost savings by enabling more people to be cured of HCV. PMID- 30288312 TI - Concordance between self-reported and measured HIV and hepatitis C virus infection status among people who inject drugs in Germany. AB - Background: People who inject drugs (PWID) are disproportionately affected by both HIV and hepatitis C infection (HCV). Awareness of infection status is essential to ensure linkage to appropriate healthcare for those infected, who need treatment and regular follow-up, as well as for uninfected individuals, who need access to targeted testing and counselling services. In this paper we compare self-reported HIV and HCV status with serological markers of infection among PWID recruited through respondent driven sampling. Methods: From 2011 through 2014, biological and behavioural data was collected from 2,077 PWID in Germany. Dried blood spots from capillary blood samples were collected and screened for HCV antibodies, HCV RNA and HIV-1/-2 antibodies. HIV reactive samples were confirmed by Western blot. Results: Laboratory testing revealed that 5 % were infected with HIV and 81 % were aware of being infected. Chronic HCV infection was detected in 41 % of the participants, 2 % had an acute HCV infection, 22 % had a cleared infection, and 34 % were unexposed to HCV. The concordance between self-reported and measured HCV status was lower than for HIV, with 73 % of those with chronic HCV infection being aware of their infection. Conclusions: We found a relatively high awareness of HIV and HCV infection status among PWID. Nevertheless, access to appropriate testing, counselling and care services targeted to the needs of PWID should be further improved, particularly concerning HCV. Trial registration: Ethical approval was received from the ethics committee at the medical university of Charite, Berlin, Germany in May 2011 and with an amendment approved retrospectively on 19/11/2012 (No EA4/036/11). The German Federal Commissioner for Data Protection and Freedom of Information approved the study protocol retrospectively on 29/11/2012 (III-401/008#0035). PMID- 30288315 TI - The hurdle with remaining risk for hepatocellular carcinoma in cirrhotic patients after a hepatitis C cure. AB - After introduction of new direct acting antivirals (DAAs) against hepatitis C, the cure rate has increased substantially especially in patients with liver cirrhosis. Decreased but remaining risk for hepatocellular carcinoma (HCC) has been shown in patients with liver cirrhosis after cure, in previous studies with interferon (IFN)-based treatments. This risk for HCCs is expected to become the next hurdle in the management of hepatitis C patients, as the number of treated and cured patients with liver cirrhosis is increasing dramatically. At the recent International Liver Congress 2016, Barcelona, Spain, a potentially alarming report was presented by Buonfiglioli F et al., among otherwise positive reports, for patients with prior HCC being treated with DAAs. This preliminary report showed a high early recurrence rate of 29 % for HCC after initiation of DAA treatment in patients with treated HCC, at follow-ups 12-24 weeks post-treatment. Another study was published just prior to this report by Reig M et al. showing similarly high recurrence rate for HCC. In this study, patients who have been treated for HCC with ablation, resection or transarterial chemoembolization, and no sign of remaining HCC at treatment start, were analysed for the risk of HCC recurrence after DAA treatment initiation. After a median follow-up time of 5.7 months, recurrence rate of HCC was seen in 28 %. The disadvantage of these studies was the lack of any control group, but these figures were unexpectedly high compared to figures in previous studies. These findings need to be further explored and eventually confirmed in other studies before making any firm conclusions and change of the routine practice. Until we have more data, the eventual risks for early HCC recurrence and other risks must be weighed against other benefits of these DAAs, halting liver disease progression, on an individual basis. PMID- 30288314 TI - Antiretroviral therapy and liver disease progression in HIV and hepatitis C co infected patients: a systematic review and meta-analysis. AB - Background: HIV co-infection exacerbates hepatitis C disease, increasing the risk of cirrhosis and hepatitis C-related mortality. Combination antiretroviral therapy (cART) is the current standard treatment for co-infected individuals, but the impact of cART and antiretroviral (ARV) monotherapy on liver disease in this population is unclear. We aimed to assess the effect of cART and ARV monotherapy on liver disease progression and liver-related mortality in individuals co infected with HIV and chronic hepatitis C. Methods: A systematic review with meta analyses was conducted. MEDLINE and EMBASE bibliographic databases were searched up to September 2015. Study quality was assessed using a modified Newcastle Ottawa scale. Results were synthesised narratively and by meta-analysis. Results: Fourteen observational studies were included. In analyses that adjusted for potential confounders, risk of liver-related mortality was significantly lower in patients receiving cART (hazard ratio/odds ratio 0.31, 95 % CI 0.14 to 0.70). Results were similar in unadjusted analyses (relative risk 0.40, 95 % CI 0.29 to 0.55). For outcomes where meta-analysis could not be performed, results were less consistent. Some studies found cART was associated with lower incidence of, or slower progression of liver disease, fibrosis and cirrhosis, while others showed no evidence of benefit. We found no evidence of liver-related harm from cART or ARV monotherapy compared with no HIV therapy. Conclusions: cART was associated with significantly lower liver-related mortality in patients co-infected with HIV and HCV. Evidence of a positive association between cART and/or ARV monotherapy and liver-disease progression was less clear, but there was no evidence to suggest that the absence of antiretroviral therapy was preferable. PMID- 30288316 TI - Roundtable discussion: how the World Hepatitis Summit 2015 strengthened stakeholders' efforts to combat viral hepatitis. AB - The inaugural World Hepatitis Summit was jointly convened by the World Health Organization (WHO) and the World Hepatitis Alliance and hosted by the Scottish Government and supported by Glasgow Caledonian University and Health Protection Scotland in September 2015. The three day event convened a broad range of stakeholders to meet and share ideas, experience and best practice in addressing the many facets of viral hepatitis prevention, diagnosis and treatment. With the next World Hepatitis Summit scheduled to take place from 1 to 3 November 2017, the World Hepatitis Alliance asked Hepatology, Medicine and Policy to commission a roundtable discussion article in order to encourage reflection on how the 2015 Summit was significant for stakeholders' efforts and why it is important to keep the momentum going ahead of the World Hepatitis Summit 2017 and in the light of the newly adopted first-ever Global Health Sector Strategy on Viral Hepatitis. PMID- 30288317 TI - The Berlin Hepatitis C Manifesto: access to prevention, testing, treatment and care for people who use drugs. AB - The treatment of hepatitis C has entered a new era since the advent of curative pharmaceuticals. As policy, government and civil society assemble in response, there are still gaps to be addressed. The Manifesto on Hepatitis C and Drug Use, launched in Berlin during the Correlation Hepatitis C Initiative conference in October 2014, was formulated and endorsed by many key organizations in the hepatitis field. The Manifesto takes strides to pinpoint shortcomings in hepatitis action oriented towards the population most affected by the hepatitis C virus (HCV): active drug users. Despite a considerable amount of evidence that active drug users are disproportionately affected by HCV, barriers to care remain. Engagement with representatives of communities of people who inject drugs (PWID) is imperative in order to effectively create guidelines which reflect reality. Unfortunately, widespread systemic stigmatization and lack of trust between affected communities, decision-makers and healthcare professionals have reproduced this divide. The Berlin Manifesto has identified a disconnect between evidence and action which must be answered. In this roundtable discussion, experts from diverse parts of the hepatitis community have contributed their perspectives and experience on access to prevention, testing, and treatment for HCV in PWID. The authors discuss relevant topics such as realities of access to HCV treatment in the United Kingdom, interventions of a regional network of active drug users in Europe and lack of PWID involvement in government policy in Catalonia. Collectively they challenge the neglect of HCV in PWID by many decision-makers and health care professionals and promote a scale-up of integrated prevention and treatment strategies focusing on this population. The authors' conclusions aim to clarify the discourse on hepatitis in order to prevent disease, save lives and work towards eventual hepatitis elimination.

AB - Background: HCV/HIV coinfection in people who inject drugs is a public health issue, which presents a variety of challenges to healthcare providers. The determinants of HCV/HIV coinfection in this population are nonetheless not well known. The aim of the present study is to identify the factors associated with HCV/HIV coinfection in people who inject drugs and enter drug-related treatment. Methods: Linked serological and behavioral data were collected from people who entered 38 opioid substitution treatment clinics in central and southern Greece between January and December 2013. Three mutually exclusive groups were defined based on the presence of HCV and HIV antibodies. Group 1 clients had neither infection, Group 2 had HCV but not HIV, and Group 3 had HCV/HIV coinfection. Multinomial logistic regression analyses identified differences between groups according to socio-demographic, drug use and higher-risk behavioral characteristics. Results: Our study population consisted of 580 people who injected drugs in the past 12 months (79.8 % males, with median age 36 years).79.4 % were HCV and 15.7 % HIV infected. Of those with complete serological data in both HCV and HIV indicators, 20.4 % were uninfected, 64.0 % HCV monoinfected, and 14.9 % HCV/HIV coinfected. HCV infection with or without HIV coinfection was positively associated with living alone or with a spouse/partner without children, prior incarceration, drug injecting histories of >=10 years, and syringe sharing in the past 12 months, and negatively associated with never having previously been tested for HCV. HCV/HIV coinfection, but not HCV infection alone, was positively associated with residence in urban areas (relative risk ratio [RRR] = 4.8, 95 % confidence interval [CI]: 1.7-13.7, p = 0.004) and averaging >3 injections a day in the past 30 days (RRR = 4.5, 95 % CI: 1.6-12.8, p = 0.005), and negatively associated with using a condom in the last sexual intercourse. Conclusions: People who inject drugs and live in urban areas and inject frequently have higher risk of coinfection. Findings highlight the need for scaling-up needle and syringe programs in inner city areas and promoting access of this population to screening and treatment, especially in prisons. The protective role of living with parents and children could inform the implementation of indicated interventions. PMID- 30288319 TI - Innovative sources for funding of viral hepatitis prevention and treatment in low and middle-income countries: a roundtable meeting report. AB - Hepatitis B is preventable and hepatitis C is treatable even if still at a high cost; most people who are infected with hepatitis B or C virus have not been screened yet and are unaware of their infections; and most countries, especially developing countries, do not have a national plan to prevent and control viral hepatitis. The advent of effective new treatments for hepatitis C has been an agent of change, allowing consideration of the feasibility of eliminating that disease and accelerating the control of viral hepatitis generally. These facts inspired the Viral Hepatitis Prevention Board (VHPB) to organize a meeting in London (8-9 June 2015) on innovative sources for funding of viral hepatitis prevention and treatment in low- and middle-income countries. The main focus of the meeting was to provide an overview of current health systems controlling viral hepatitis in low- and middle-income countries (LMICs); to identify ways to increase political commitment and financial sustainability of viral hepatitis prevention and control programmes in such countries; to identify potential funders and explore new funding mechanisms; to discuss lessons learnt about funding other disease programmes; to investigate how to convince and motivate decision-makers to fund viral hepatitis programmes in LMICs; to provide options for improving access to affordable screening and treatment of viral hepatitis in LMICs; and to list the commitments required for funding by donors, including governments, bilateral and multilateral organizations, non-traditional donors, development banks, foundations, and commercial financial institutions. To improve viral hepatitis prevention and treatment in LMICs participating hepatitis and financing experts identified the most urgent needs. Data on burden of disease must be improved. Comprehensive hepatitis policies and strategies should be drafted and implemented, and existing strategies and policies improved to increase access to treatment and prevention. Strong political will and leadership should be generated, potential partners identified and partnerships created. Potential funders and funding mechanisms have to be researched. The outcome of this meeting was integrated in a VHPB project to investigate creative financing solutions to expand access to and provision of screening and other preventive services, treatment and care of hepatitis B and C in LMICs. The report is available on www.vhpb.org. PMID- 30288320 TI - Incidence of hepatitis C among people who inject drugs in Ireland. AB - Background: Comprehensive information on the incidence and duration of hepatitis C virus (HCV) infection for people who inject drugs (PWID) in Ireland is not available. We created an incidence curve of injecting drug use in Ireland and subsequently estimated incidence of hepatitis C virus (HCV) infection. Methods: Anonymised data from the National Drug Treatment Reporting System (NDTRS) were used to identify all people who inject drugs (PWIDs) and who entered drug treatment for the first time between 1991 and 2014. A curve, estimating the incidence of injecting, was created to plot PWIDs by year of commencing injecting. The curve was adjusted for missing data on PWIDs in treatment and for PWIDs who were never treated. An adjustment was made to account for injectors who had never shared injecting equipment. The incidence of HCV infection and chronic infection in PWIDs was estimated by applying published rates. Results: Between 1991 and 2014, 14,320 injectors were registered on NDTRS. The majority were young (median age 25 years), male (74%), lived in Dublin (73%) and injected an opiate (e.g. heroin) (94%). The estimated total number of injectors up to the end of 2014 was 16,382. An estimated 12,423 (95% CI 10,799-13,161) were infected with HCV, and 9,317 (95% CI 8,022-9,996) became chronically infected. The estimated annual number of new HCV infections among PWIDs increased steeply from the late 1970s and peaked in 1998. By 2014, almost 30% of injectors were estimated to have been infected for over 20 years. Conclusions: This is the first comprehensive national estimate of the incidence of HCV in PWIDs in Ireland and will inform planning and developing appropriate health care services. PMID- 30288321 TI - Highlights from the 3rd international HIV/viral hepatitis Co-infection meeting - HIV/viral hepatitis: improving diagnosis, antiviral therapy and access. AB - The International AIDS Society convened the 3rd International HIV/Viral Hepatitis Co-Infection Meeting on 17 July 2016 as part of the pre-conference program preceding the 21st International AIDS Conference held in Durban, South Africa. The meeting brought together a diversity of scientific, technical and community interests to discuss opportunities and challenges for increased prevention, diagnosis and treatment of viral hepatitis in people living with HIV, particularly in low- and middle-income settings. The objectives of the meeting were:i.To review the latest therapeutic developments in viral hepatitis;ii.To identify challenges such as high cost of medications for hepatitis C virus (HCV) and risk of developing viral resistance, and successes, such as the provision of HCV treatment in community-based settings, movements to reduce drug costs and increasing access, in relation to scaling up diagnosis, screening, antiviral treatment and prevention of viral hepatitis;iii.To advance the agenda for elimination of viral hepatitis as a public health problem. Discussions centred around the six key interventions outlined by the World Health Organization Global Health Sector Strategy on Viral Hepatitis 2016-2021: hepatitis B virus (HBV) vaccination (including birth dose); safe injection practices plus safe blood; harm reduction among people who inject drugs; safer sex practices; hepatitis B treatment; and hepatitis C cure. This article summarizes the main issues and findings discussed during the pre-conference meeting. One of the recommendations from the meeting delegates is universal implementation of birth dose vaccination for HBV without further delay to prevent mother-to-child transmission of infection. There is also the need to implement screening and treatment of hepatitis among pregnant women. A call was made for concerted efforts to be put together by all stakeholders towards addressing some of the structural barriers, including criminalization of drug use, discrimination and stigma that people living with viral hepatitis face. Finally, the need for greater advocacy was highlighted to enable access to therapy of viral hepatitis at lower cost than currently prevails. Implementation of these resolutions will help in achieving the target of eliminating viral hepatitis as a public health threat.

AB - Introduction: The 16 countries of the Eastern Europe and Central Asia (EECA) region are home to 6.6 million people in need of treatment for chronic hepatitis C virus (HCV) infection. Because of transformational change in HCV treatment, global efforts to address HCV are accelerating. Given its large regional burden, the EECA needs to ensure its inclusion in and benefit from any new developments. Methods: Our 2015-16 survey aimed to collect and report on epidemiology, treatment access (including drug registration and prices, national HCV guidelines and treatment program coverage) and pertinent civil society organization (CSO) activities in 11 countries in the EECA. Results: Major gaps in epidemiological data exist; reported anti-HCV prevalence ranged from 1.5 to 7.5% for the general population, 22.7 to 70-95% for people who inject drugs (PWID) and 18 to 80% for people living with HIV (PLHIV). Ten countries (91% of the sample) have registered one or more of the second-generation, direct-acting antiviral medications (DAA) for potential interferon-free treatment. However, intellectual property issues and prices limit access to these drugs. In 2014, HCV programs in the surveyed countries covered only 0.15% of the total number of people in need of treatment. CSO-driven, international donor-funded programs are starting to fulfill needs of PWID and PLHIV. Conclusions: As feasible curative HCV treatment is now available, and given the significant regional disease burden, EECA countries need to ensure HCV surveillance and DAA availability at affordable prices in order to expand treatment and prevent the onward transmission of the infection. EECA CSOs have demonstrated their capacity to play a crucial role in advancing HCV issues, and they should continue leveraging these issues for the benefit of individual patients and public health in general. PMID- 30288324 TI - "B in IT" - a community-based model for the management of hepatitis B patients in primary care clinics using a novel web-based clinical tool. AB - Background: The current model of care for the treatment of chronic hepatitis B (CHB) in Australia is through specialist Hepatology or Infectious Diseases clinics, and limited accredited primary care practices. Capacity is limited, and less than 5% of Australians living with CHB currently access therapy. Increasing treatment uptake is an urgent area of clinical need. Nucleos(t)ide analogue therapy is safe and effective treatment for CHB that is suitable for community prescribing. We have evaluated the success of a community-based model for the management of CHB in primary care clinics using a novel web-based clinical tool. Methods: Using guidelines set out by the Gastroenterological Society of Australia, we developed an interactive online clinical management tool for the shared care of patients with CHB in primary care clinics, with remote oversight from tertiary hospital-based hepatologists and a project officer. We call this model of care the "B in IT" program. Suitable patients were referred from the specialist liver clinic back to primary care for ongoing management. Compliance with recommended appointments, pathology tests and ultrasounds of patients enrolled in "B in IT" was assessed and compared to that of the same patients prior to community discharge, as well as a matched control group of CHB outpatients continuing to attend a specialist clinic. Results: Thirty patients with CHB were enrolled in the "B in IT" program. Compliance with attending scheduled appointments within 1 month of the suggested date was 87% across all 115 visits scheduled. Compliance with completing recommended pathology within 1 month of the suggested date was 94% and compliance with completing recommended liver ultrasounds for cancer screening within 1 month of the suggested date was 89%. The compliance rates for visit attendance and ultrasound completion were significantly higher than the control patient group (p < 0.0001) and the "B in IT" patients prior to community discharge (p = 0.002 and p = 0.039, respectively). Conclusions: The "B in IT" program's novel web-based clinical tool supports primary care physicians to treat and monitor patients with CHB. This program promotes community-based care and increases system capacity for the clinical care of people living with CHB. PMID- 30288323 TI - A school-based intervention of screening a movie to increase hepatitis B vaccination levels among students in Uttar Pradesh, India: impact on knowledge, awareness, attitudes and vaccination levels. AB - Background: India is home to one in 14 of all chronic hepatitis B virus (HBV) cases, meaning that it is important to develop HBV interventions that are applicable in the Indian context. Vaccination is the foremost tool for interrupting the HBV infection cycle. HBV vaccination was not included in India's government-sponsored expanded immunisation program until 2011, and many children born earlier remain unvaccinated. This study sought to observe the impact of the HOPE Initiative's school-based intervention to increase vaccination coverage by increasing HBV awareness among students in Lucknow, Uttar Pradesh. Methods: At 430 schools in the administrative areas within and surrounding Lucknow, students viewed an educational documentary film on HBV and completed two questionnaires, one immediately before the screening and the other six weeks later. Both questionnaires asked the same 14 questions, which were organized into five domains: knowledge of the magnitude of the problem of HBV; knowledge of modes of HBV transmission; knowledge of consequences of HBV infection; awareness of HBV; and attitudes regarding HBV. The baseline questionnaire also asked students whether they had been vaccinated against HBV. At two-year follow-up, researchers measured vaccination levels at a subset of 30 intervention schools and six non intervention schools to further assess the impact of the intervention. Results: Baseline questionnaires were completed by 11,250 students, and post-intervention questionnaires, by 9698 students. Scores for knowledge about the magnitude of the HBV problem improved from 41% at baseline to 74% at follow-up, and scores for knowledge about modes of transmission, from 38% to 75% (p < 0.05 for both). The baseline HBV vaccination level among students receiving the intervention was 21%. Two years after the intervention, 45% of students (N = 4284) reported being vaccinated at intervention schools compared to 22% (N = 1264) at non-intervention schools. Conclusions: The observed increases in HBV awareness, knowledge and vaccination levels in this study indicate that school-based interventions can be used to achieve higher vaccination coverage among Indian children. The documentary film was found to be an affordable tool for reaching large audiences. More studies are needed to validate the impact of this intervention and to explore its applicability to other social causes. PMID- 30288325 TI - Post-infection viral superinfection technology could treat HBV and HCV patients with unmet needs. AB - Background: Viral hepatitis deaths from acute infection, cirrhosis, and liver cancer have risen from the tenth to the seventh leading cause of death worldwide between 1990 and 2013. Even in the oral direct acting antiviral (DAA) agent era there are still large numbers of patients with unmet needs. Medications approved for treatment of chronic hepatitis B virus (HBV) infection do not eradicate HBV often requiring treatment for life associated with risks of adverse reactions, drug resistance, nonadherence, and increased cost. Although DAAs increased virologic cure rates well over 90% in all hepatitis C virus (HCV) genotypes, HCV infection still cannot be cured in a small but significant minority of patients. While most of the medical issues of HCV treatment have been solved, the current costs of DAAs are prohibitive. Results: The post-infection viral superinfection treatment (SIT) platform technology has been clinically proven to be safe and effective to resolve acute and persistent viral infections in 42 HBV and HCV patients (20 HBV, 22 HCV), and in 4 decompensated patients (2 HBV, 2 HCV). SIT employs a non-pathogenic avian double stranded RNA (dsRNA) virus, a potent activator of antiviral gene responses. Unexpectedly, SIT is active against unrelated DNA (HBV) and RNA (HCV) viruses. SIT does not require lifelong therapy, which is a major advantage considering present HBV treatments. The new viral drug candidate (R903/78) is homogeneously produced by reverse genetics in Vero cells. R903/78 has exceptional pH and temperature stability and also excellent long-term stability; therefore, it can be orally administered, stored and shipped without freezing. Since R903/78 is easy to stockpile, the post-infection SIT could also alleviate the logistic hurdles of surge capacity in vaccine production during viral pandemics. Conclusion: To help large number of HBV and HCV patients with unmet needs, broad-spectrum antiviral drugs effective against whole classes of viruses are urgently needed. The innovative SIT technological platform will be a great additional armament to conquer viral hepatitis, which is still a major cause of death and disability worldwide. PMID- 30288326 TI - Uptake of hepatitis B-HIV co-infection screening and management in a resource limited setting. AB - Background: WHO hepatitis B guidelines recommend testing all new HIV patients, treating them accordingly or providing immunization. At the Infectious Diseases Institute (IDI) following an audit done in 2012, only 46% patients had been screened for hepatitis B with variable management plans therefore new internal guidelines were implemented. This study describes the uptake of hepatitis B screening and management of patients with hepatitis B and HIV con-infection after the implementation. Methods: Data included for all HIV positive patients in care at IDI by October 2015. Data are expressed as median with interquartile range (IQR) and percentages were compared using the chi square test. Statistical analysis was performed using STATA version 13. The IDI laboratory upper limit of normal for alanine aminotransferase (ALT) and aspartate aminotransferase (ASTs) was 40 IU/ml. Results: Number of hepatitis B screening tests increased from 800 by 2012 to 1400 in 2015. By 2015 8042/8604(93.5%) patients had been screened for hepatitis B. Overall hepatitis B positive were 359 (4.6%). 166 (81.4%) hepatitis B positives were switched to a tenofovir (TDF) containing regimen. Conclusion: Our study confirms the importance of screening for hepatitis B and of using ART regimens containing tenofovir in hepatitis B co-infected patients. Whilst our program has made improvements in care still 18.6% of patients with hepatitis B were not on tenofovir regimens, 98.1% had no hepatitis B viral loads done. Clinicians should recognize the potential for hepatitis B in HIV positive patients and the importance of early diagnosis and treatment to ensure optimal management of cases and follow up. PMID- 30288328 TI - Re-evaluation of chronic hepatitis B and hepatitis C patients lost to follow-up: results of the Northern Holland hepatitis retrieval project. AB - Background: Many persons infected with Hepatitis B virus (HBV) and Hepatitis C virus (HCV) in the past are now lost to follow-up. The aim of the Northern Holland Hepatitis Retrieval Project (NHHRP) is to retrieve and re-evaluate persons previously diagnosed with HBV or HCV and bring them back into care. Chronic HBV infection was defined as two positive Hepatitis B surface antigen (HBsAg) tests within 6 months and chronic HCV infection with 2 positive HCV RNA tests by polymerase chain reaction (PCR). Methods: Data files of the local public health services and microbiology laboratory were explored to identify all registered HBV and HCV cases in the Alkmaar region, the Netherlands, for the past 15 years. Identified cases were compared with patients currently known in our hospital. Patients without follow-up in primary or hospital care were approached via their primary health care physician and invited for evaluation at our hospital. Results: In total, 552 cases of HBV were identified. 356 (64.5%) had no follow-up. Only 113/356 (31.7%) were eligible for retrieval and 44.2% were evaluated in our hospital resulting in a change of management in 22/50 (44%) of patients. Four hundred ninety nine cases of HCV were identified, 150/499 (30.1%) were lost to follow-up. Only 20/150 (13.3%) were eligible for retrieval and 4/20 (20%) were evaluated at our clinic. Resulting in a change of management in 3/4 (75%). Conclusion: Only a limited part of HBV and HCV persons lost to follow-up is eligible for retrieval, nonetheless re-evaluation of these persons will lead to a change of management in the majority of persons. PMID- 30288327 TI - Design of the Prospective Real-world Outcomes Study of hepatic encephalopathy Patients' Experience on Rifaximin-alpha (PROSPER): an observational study among 550 patients. AB - Background: Hepatic encephalopathy (HE) is one of the most important severe complications of liver cirrhosis. Thought to be caused by elevated blood levels of gut-derived neurotoxins (particularly ammonia) entering the brain, HE manifests as a wide range of neurological or psychiatric abnormalities, which increase the risk of mortality, result in substantial morbidity and negatively affect the quality of life (QoL) of both patients and their caregivers. HE is also associated with a substantial economic burden. Rifaximin-alpha 550 mg is a locally acting oral antibiotic that reduces the effects of ammonia-producing intestinal flora, and which is used to help reduce the recurrence of overt HE. The efficacy of rifaximin-alpha 550 mg was established in a randomised controlled trial and long-term extension study. However, 'real-world' evidence is also required to assess how this efficacy may translate into effectiveness in clinical practice, including the potential impact of treatment on healthcare resource utilisation. Methods: The Prospective Real-world Outcomes Study of HE Patients' Experience on Rifaximin-alpha 550 mg (PROSPER) is a multinational, multicentre, observational study that will be conducted under real-world clinical practice conditions. Comprising a retrospective phase (up to 12 months) and a prospective phase (up to 24 months), and employing a robust statistical methodology, PROSPER has been specifically designed to minimise the bias associated with observational studies. The primary endpoint will be the effect of rifaximin-alpha 550 mg treatment on HE- and liver-related hospitalisation rate and duration of hospitalisation. Secondary endpoints will include comprehensive assessments of the impact of treatment on the QoL and workplace productivity of patients and caregivers, a global assessment of treatment effectiveness and safety/tolerability. Approximately 550 patients will be enrolled. Conclusions: PROSPER will provide valuable real-world information on the effectiveness of rifaximin-alpha 550 mg in reducing the recurrence of HE, and its impact on the QoL and work productivity of patients and their caregivers. By providing data on both the direct costs (e.g., hospitalisation rate, duration of hospitalisation) and indirect costs (such as work productivity) of HE, PROSPER should help confirm whether rifaximin-alpha 550 mg treatment represents a good use of economic resources. Trial registration: ClinicalTrials.gov identifier NCT02488993. PMID- 30288329 TI - Racial/ethnic- and county-specific prevalence of chronic hepatitis B and its burden in California. AB - Background: In the United States, the highest burden of chronic hepatitis B (CHB) and CHB-related liver cancer is in the state of California, primarily in the San Francisco (SF) Bay and Los Angeles (LA) areas. The aim of this study was to estimate county-specific hepatitis B surface antigen (HBsAg) prevalence and quantify CHB cases by age, race/ethnicity, nativity, and disease activity status. Methods: Twelve counties in SF Bay Area and three large counties in LA area were included for this analysis. Race/ethnicity-specific prevalence of HBsAg for each county and the state of California as a whole, was estimated by including prevalence data from the National Health and Nutrition Examination Survey and various studies that estimated HBsAg prevalence in US and foreign-born Asian Pacific Islanders, Hispanic, and Black populations. In addition, clinical data of 2000 consecutive CHB patients (collected between 2009 and 2014) from a large clinical consortium in the SF Bay area were used to calculate the age-specific disease burden. Results: Of the 15 counties analyzed, SF had the highest HBsAg prevalence (1.78%), followed by Santa Clara (1.63%) and Alameda (1.45%). The majority of CHB cases were estimated to be in LA County (83,770), followed by Santa Clara (31,273), and Alameda (23,764). Among the CHB cases, 12.7% is active HBeAg positive, 24.2% is active HBeAg negative, and 10.6% has cirrhosis. Conclusion: This study confirms and quantifies the current burden of CHB in high endemic counties in the state of California using population-level estimates combined with clinical data including those from the community. PMID- 30288330 TI - Hepatitis C virus prevention and care for drug injectors: the French approach. AB - After France removed hepatitis C treatment reimbursement restrictions on 25 May 2016, an expert report presented recommendations, which focused on vulnerable groups including people who inject drugs (PWID). This commentary presents the key points of the chapter with a particular focus on policy. Thanks to the official lifting of restrictions based on disease stage and to the excellent efficacy and tolerance of the new DAA (Direct-Acting Antivirals) among PWID, the main issue is to improve the HCV care cascade. In France, many HCV-infected PWID, especially active/current PWID, remain undiagnosed and unlinked to care. Our challenge is to improve HCV screening by point of care testing (POCT), outreach methods with mobile teams, rapid tests, FibroScan, etc. and to provide PWID with appropriate services in all the settings they attend, such as drug treatment or harm reduction services, social services, prisons, etc. Another important issue is the prevention of reinfection through comprehensive and long-term follow-up. The report recommends a new national policy: testing and treating PWID as a priority, since this is the best way to eliminate HCV infection. It requires a global strategy consisting of combined and long-term interventions: prevention, outreach, screening, DAA, drug treatment programs including opiate substitution treatment (OST) and various harm reduction programs, including needle exchange programs (NEP). Ideally, these services should be delivered in the same place with an integrated approach. This should lead to meeting the national objective set by the government of eliminating hepatitis C by 2025. PMID- 30288331 TI - Achieving a hepatitis C cure: a qualitative exploration of the experiences and meanings of achieving a hepatitis C cure using the direct acting antivirals in Australia. AB - Background: Universal access to the hepatitis C direct acting antiviral (DAAs) regimens presents a unique opportunity to eliminate hepatitis C in Australia. Large numbers of Australians have already been cured using these treatments, however, the numbers presenting for treatment have begun to plateau. This study explored how people experienced and understood being cured of hepatitis C, with the aim of informing interventions to increase uptake of DAA treatment among people with hepatitis C. Methods: This qualitative study used semi-structured interviews to explore the experiences of people with hepatitis C taking DAAs accessing both hospital and community clinics. Interviews were conducted 12 weeks after treatment completion. Participants were asked to reflect on their experience of living with hepatitis C, their reasons for seeking treatment, and their experience of, DAA treatments. Participants were also asked to reflect on the meaning of being cured, and how they shared this experience with their peers. Interviews were transcribed verbatim and key themes were identified using inductive thematic analysis. Results: Twenty participants were interviewed. While participants described a range of physical health benefits of achieving a hepatitis C cure it was an improved sense of psychological wellbeing that had the most significant impact on participants' lives. The majority described their relief about no longer living with the burden of an uncertain future due to anxiety about developing liver disease or cancer, as well as fear of infecting others. Participants who had a past history of injecting drug use, described being cured as a way to break the connection with their past. Participants who were current injectors raised concerns about re-infection. Conclusion: Feeling "normal" and not infectious allows people to live with reduced psychological distress, in addition to the physical benefits of no longer being at risk of developing serious liver disease. Future engagement strategies targeting people who are not accessing hepatitis health care need to promote the lived experience of being cured and the substantial psychological, and physical health benefits, offered by achieving a cure. Interventions aimed at people who are currently injecting also need to highlight the availability of re-treatment in conjunction with primary prevention strategies. PMID- 30288332 TI - Drug consumption rooms (DCRs) as a setting to address hepatitis C - findings from an international online survey. AB - Background: Prevalence of Hepatitis C Virus (HCV) among people who inject drugs (PWID) is high. Risky injecting behaviours have been found to decrease in drug consumption rooms (DCRs) and supervised injecting facilities (SIFs), yet HCV prevention and treatment in these settings have not been extensively explored. Methods: To determine the range and scope of HCV prevention and treatment options in these services, we assessed DCR/SIF operational features, their clients' characteristics and the HCV-related services they provide. A comprehensive online survey was sent to the managers of the 91 DCRs/SIFs that were operating globally as of September 2016. A descriptive cross-country analysis of the main DCR/SIF characteristics was conducted and bivariate logistic models were used to assess factors associated with enhanced HCV service provision. Results: Forty-nine valid responses were retrieved from DCRs/SIFs in all countries where they were established at the time of the survey (Australia, Canada, Denmark, France, Germany, Luxembourg, Netherlands, Norway, Spain and Switzerland). Internationally, the operational capacities of DCRs/SIFs varied in terms of funding, location, size and staffing, but their clients all shared common features of vulnerability and marginalisation. Estimated HCV prevalence rates were around 60%. Among a range of health and social services and referrals to other programs, most DCRs/SIFs provided HCV testing onsite (65%) and/or offered liver monitoring or disease management (54%). HCV treatment onsite was offered or was planned to be offered by 21% of DCRs/SIFs. HCV testing onsite was associated with provision of other services addressing blood-borne diseases and HCV treatment was linked to the provision of OST. HCV disease management was associated with employing a nurse at a DCR/SIF and HCV treatment was associated with employing a medical doctor. Conclusions: DCRs/SIFs offer easy-to-access HCV related services for PWID. The availability of onsite medical professionals and provision of support and education to non-medical staff are key to enhanced provision of HCV-related services in DCRs/SIFs. Funding and support for HCV treatment at the community level, via low-threshold services such as DCRs/SIFs, are worthy of action. PMID- 30288333 TI - Seroprevalence of hepatitis B and C in Nepal: a systematic review (1973-2017). AB - Introduction: Hepatitis B and C represent an important co-infection for people living with HIV worldwide. Nepal wants to be part of the international mobilization for viral hepatitis elimination, and has pursued better understanding of the epidemic in its territory through scientific research. Methods: We performed a systematic review of seroprevalence studies hepatitis B and C in Nepal following the PRISMA 2009 Flow Diagram. Results: Fifty-four scientific publications and reports were selected for this review. Nearly a quarter of these documents have been issued in recent years and many are authored by non-governmental organizations in Nepal. The collective of information displays a wide range of alarming prevalence rates, particularly for girls and women survivors of human trafficking and a progressive participation of civil society in viral hepatitis epidemiology research in the country. Conclusion: This paper presents a most complete review of hepatitis B and C and HIV co-infection prevalence studies in different population groups from 1973 to 2016. A comprehensive analysis of the epidemiology and apparent trends in public health research and policy making in Nepal are also addressed in this document. We expect this to be a most important tool for improvements in future interventions for both epidemics in the country. PMID- 30288334 TI - Strategies for achieving viral hepatitis C micro-elimination in the Netherlands. AB - The Netherlands is striving to achieve national elimination of the hepatitis C virus (HCV) as one of the first countries worldwide. The favorable HCV epidemiology with both low prevalence and incidence, together with access to care and treatment, present excellent conditions to further build on towards this objective. The Dutch national plan on viral hepatitis, introduced in 2016, defines targets in the HCV healthcare cascade and provides a structural framework for the development of elimination activities. Since many different stakeholders are involved in HCV care in the Netherlands, focus has been placed on micro elimination initiatives as a pragmatic and efficient approach. These numerous micro-eliminations projects have brought the Netherlands closer to HCV elimination. In the near future, efforts specifically have to be made in order to optimize case-finding strategies and to successfully accomplish the nationwide implementation of the registration and monitoring system of viral hepatitis mono infections, before this final goal can be reached. The upcoming years will then elucidate if the Dutch' hands on approach has resulted in sufficient progress against HCV and if the Netherlands will lead the way towards nationwide HCV elimination. PMID- 30288335 TI - The Community Health Experience Model-value generation from person-centered health transaction network. AB - Background: Network society is creating new opportunities for value generation in all areas of our lives: new collaborative methods and tools are increasingly available for use by closely connected individuals and organizations. The stakeholders of the health ecosystem are potential winners of this networking process as a consequence of the increase in knowledge about health value generation supported by teamwork and collaborative approaches in this field. Case Presentation: In this paper, we focus on the transactional nature of health value generation networks. First, we analyze the transactions in the networks. We then propose a design structure-the Community Health Experience Model-for effective person-centered health value generation networks. In the second phase of the work, we describe how the system design of the complete transaction network was tested in a real-life pilot environment focusing on fall prevention in individuals with osteoporosis.As a result of the network-based collaborative service approach, fall risk decreased by 11.8% and the number of falls decreased by 4.5% within 3 months. Regarding the major health experience outcomes, self evaluated condition-specific health literacy improved from 7.85 to 8.26 (an improvement of 0.41), while self-evaluated condition-specific self-management capability changed from 7.25 to 8.06 (0.81 improvement). Conclusions: In conclusion, the proposed Community Health Experience Model is a novel and promising approach to designing the structure of more effective and efficient health services and collaborative networks.

AB - Background: Pediatric patients presenting with a nasal mass is uncommon and a high index of suspicion for it to be a meningoencephalocele is essential. Majority of these are congenital and require early intervention owing to the risk of meningitis. Surgery in these cases is very challenging because of the risk of anesthesia and limited space. Objective: This study aimed to describe our technique and experience in managing pediatric meningoencephaloceles. Methods: A retrospective study of 19 pediatric patients (age ranging from 40-day-old infants to 11.5-year-old children) was conducted at our tertiary care center from January 2012 to February 2017. Patients presenting with an intranasal meningoencephalocele were treated by endoscopic approach, using otological microinstruments. After detailed imaging and clinical evaluation, a tailored repair, using fat/fascia/cartilage, a multilayer closure, was carried out in all cases. Results: All patients had a successful repair and recovery, except for one death following an episode of convulsion. There was a minor circumferential narrowing of the nasal vestibule and synechia formation in 2 of our cases. Conclusion: Transnasal endoscopic repair of meningoencephalocele is minimally invasive. It avoids permanent anosmia and is cosmetic. A combination of miniaturized instruments and a 4-mm 0 degrees nasal endoscope gives excellent visual field and an adequate working space. Owing to the larger defects in congenital meningoencephaloceles, a multilayer repair provides excellent outcomes. PMID- 30288337 TI - Erratum. AB - [This corrects the article DOI: 10.1177/2152656718783630.]. PMID- 30288338 TI - Iridium Catalysts for Acceptorless Dehydrogenation of Alcohols to Carboxylic Acids: Scope and Mechanism. AB - We introduce iridium-based conditions for the conversion of primary alcohols to potassium carboxylates (or carboxylic acids) in the presence of potassium hydroxide and either [Ir(2-PyCH2(C4H5N2))(COD)]OTf (1) or [Ir(2-PyCH2PBu2 t)(COD)]OTf (2). The method provides both aliphatic and benzylic carboxylates in high yield and with outstanding functional group tolerance. We illustrate the application of this method to a diverse variety of primary alcohols, including those involving heterocycles and even free amines. Complex 2 reacts with alcohols to form crystallographically-characterized catalytic intermediates [IrH(eta 1,eta 3-C8H12)(2-PyCH2PtBu2)] (2a) and [Ir2H3(CO)(2-PyCH2PtBu2){MU-(C5H3N)CH2PtBu2}] (2c). The unexpected similarities in reactivities of 1 and 2 in this reaction, along with synthetic studies on several of our iridium intermediates, enable us to form a general proposal of the mechanisms of catalyst activation that govern the disparate reactivities of 1 and 2, respectively in glycerol and formic acid dehydrogenation. Moreover, careful analysis of the organic intermediates in the oxidation sequence enable new insights into the role of Tishchenko and Cannizzaro reactions in the overall oxidation. PMID- 30288339 TI - Organ-specific metastases obtained by culturing colorectal cancer cells on tissue specific decellularized scaffolds. AB - Metastatic disease remains the primary cause of mortality in cancer patients. Yet the number of available in vitro models to study metastasis is limited by challenges in the recapitulation of the metastatic microenvironment in vitro, and by difficulties in maintaining colonized-tissue specificity in the expansion and maintenance of metastatic cells. Here, we show that decellularized scaffolds that retain tissue-specific extracellular-matrix (ECM) components and bound signaling molecules enable, when seeded with colorectal cancer (CRC) cells, the spontaneous formation of three-dimensional cell colonies that histologically, molecularly and phenotypically resemble in vivo metastases. Lung and liver metastases obtained by culturing CRC cells on, respectively, liver and lung decellularized scaffolds retained their tissue-specific tropism when injected in mice. We also found that the engineered metastases contained signet ring cells, which has not previously been observed ex vivo. A culture system with tissue-specific decellularized scaffolds represents a simple and powerful approach for the study of organ specific cancer metastases. PMID- 30288340 TI - Long-term outcomes of a phase I study of agonist CD40 antibody and CTLA-4 blockade in patients with metastatic melanoma. AB - We report long-term clinical outcomes and immune responses observed from a phase 1 trial of agonist CD40 monoclonal antibody (mAb) and blocking CTLA-4 mAb in patients with metastatic melanoma. Twenty-four patients previously untreated with checkpoint blockade were enrolled. The agonistic CD40 mAb CP-870,893 and the CTLA 4 blocking mAb tremelimumab were dosed concomitantly every 3 weeks and 12 weeks, respectively, across four dose combinations. Two patients developed dose-limiting grade 3 immune-mediated colitis that led to the definition of the maximum tolerated dose (MTD). Other immune-mediated toxicity included uveitis (n = 1), hypophysitis (n = 1), hypothyroidism (n = 2), and grade 3 cytokine release syndrome (CRS) (n = 1). The estimated MTD was 0.2 mg/kg of CP-870,893 and 10 mg/kg of tremelimumab. In 22 evaluable patients, the objective response rate (ORR) was 27.3%: two patients (9.1%) had complete responses (CR) and four (18.2%) patients had partial responses (PR). With a median follow-up of 45 months, the median progression-free survival (PFS) was 3.2 months (95% CI, 1.3-5.1 months) and median overall survival (OS) was 23.6 months (95% CI, 11.7-35.5 months). Nine patients are long-term survivors (> 3 years), 8 of whom subsequently received other therapy including PD-1 mAb, surgery, or radiation therapy. Elevated baseline soluble CD25 was associated with shorter OS. Immunologically, treatment was associated with evidence of T cell activation and increased tumor T cell infiltration that was accomplished without therapeutic PD-1/PD-L1 blockade. These results suggest opportunities for immune activation and cancer immunotherapy beyond PD-1. PMID- 30288341 TI - A novel function of API5 (apoptosis inhibitor 5), TLR4-dependent activation of antigen presenting cells. AB - Dendritic cell (DC)-based vaccines are recognized as a promising immunotherapeutic strategy against cancer. Various adjuvants are often incorporated to enhance the modest immunogenicity of DC vaccines. More specifically, many of the commonly used adjuvants are derived from bacteria. In the current study, we evaluate the use of apoptosis inhibitor 5 (API5), a damage associated molecular pattern expressed by many human cancer cells, as a novel DC vaccine adjuvant. We showed that API5 can prompt activation and maturation of DCs and activate NFkB by stimulating the Toll-like receptor signaling pathway. We also demonstrated that vaccination with API5-treated DCs pulsed with OVA, E7, or AH1-A5 peptides led to the generation of OVA, E7, or AH1-A5-specific CD8 + T cells and memory T cells, which is associated with long term tumor protection and antitumor effects in mice, against EG.7, TC-1, and CT26 tumors. Additionally, we determined that API5-mediated DC activation and immune stimulation are dependent on TLR4. Lastly, we showed that the API5 protein sequence fragment that is proximal to its leucine zipper motif is responsible for the adjuvant effects exerted by API5. Our data provide evidence that support the use of API5 as a promising adjuvant for DC-based therapies, which can be applied in combination with other cancer therapies. Most notably, our results further support the continued investigation of human-based adjuvants. PMID- 30288342 TI - A point mutation in the Ncr1 signal peptide impairs the development of innate lymphoid cell subsets. AB - NKp46 (CD335) is a surface receptor shared by both human and mouse natural killer (NK) cells and innate lymphoid cells (ILCs) that transduces activating signals necessary to eliminate virus-infected cells and tumors. Here, we describe a spontaneous point mutation of cysteine to arginine (C14R) in the signal peptide of the NKp46 protein in congenic Ly5.1 mice and the newly generated NCRB6C14R strain. Ly5.1C14R NK cells expressed similar levels of Ncr1 mRNA as C57BL/6, but showed impaired surface NKp46 and reduced ability to control melanoma tumors in vivo. Expression of the mutant NKp46C14R in 293T cells showed that NKp46 protein trafficking to the cell surface was compromised. Although Ly5.1C14R mice had normal number of NK cells, they showed an increased number of early maturation stage NK cells. CD49a+ILC1s were also increased but these cells lacked the expression of TRAIL. ILC3s that expressed NKp46 were not detectable and were not apparent when examined by T-bet expression. Thus, the C14R mutation reveals that NKp46 is important for NK cell and ILC differentiation, maturation and function. Significance Innate lymphoid cells (ILCs) play important roles in immune protection. Various subsets of ILCs express the activating receptor NKp46 which is capable of recognizing pathogen derived and tumor ligands and is necessary for immune protection. Here, we describe a spontaneous point mutation in the signal peptide of the NKp46 protein in congenic Ly5.1 mice which are widely used for tracking cells in vivo. This Ncr1 C14R mutation impairs NKp46 surface expression resulting in destabilization of Ncr1 and accumulation of NKp46 in the endoplasmic reticulum. Loss of stable NKp46 expression impaired the maturation of NKp46+ ILCs and altered the expression of TRAIL and T-bet in ILC1 and ILC3, respectively. PMID- 30288343 TI - Tumor infiltrating CD19+ B lymphocytes predict prognostic and therapeutic benefits in metastatic renal cell carcinoma patients treated with tyrosine kinase inhibitors. AB - The objective response rate (ORR) of tyrosine kinase inhibitors (TKIs) therapy in metastatic renal cell cancer (mRCC) patients was not satisfactory. Effective indicator of mRCC patient selection for TKI therapy is urgently needed. The function of tumor infiltrating B lymphocytes (TIBs) in tumor immune elimination is still unclear. We aim to investigate the prognostic and predictive value of TIBs for TKI therapy in mRCC patients in this study. 108 eligible patients treated with TKI were enrolled in this study. TIBs was estimated by immunohistochemical staining of CD19 in the resected tumor, and its relationship with clinicopathological features, clinical outcomes and CD8+ tumor infiltrating T lymphocytes (CD8+ TILs) were evaluated. Associations between the expression level of CD19 and CD8+ TILs associated cytotoxic effectors were also assessed in public databases. Results showed TIBs positive infiltration predicted better therapeutic response to sunitinib (p = 0.006), longer overall survival (OS) (p < 0.001) and progression-free survival (PFS) (p = 0.028) in mRCC patients. Combining TIBs and International Metastatic Renal-Cell Carcinoma Database Consortium (IMDC) model showed a better predict value of OS in TKI-treated mRCC patients than IMDC model alone. We also found a positive correlation between TIBs and CD8+ TILs (p < 0.001). Patients with both cells high infiltration showed markedly better OS compared with those infiltrated by CD8+ T cells alone (p = 0.015). To conclude, TIBs density was not only an independent prognostic factor for mRCC patients, but also a predictive marker for TKI therapy response. It may potently enhance the antitumor effect by recruiting and activating CD8+ TILs in mRCC. PMID- 30288344 TI - Brain tumor-initiating cells export tenascin-C associated with exosomes to suppress T cell activity. AB - The dismal prognosis of glioblastoma is attributed in part to the existence of stem-like brain tumor-initiating cells (BTICs) that are highly radio- and chemo resistant. New approaches such as therapies that reprogram compromised immune cells against BTICs are needed. Effective immunotherapies in glioblastoma, however, remain elusive unless the mechanisms of immunosuppression by the tumor are better understood. Here, we describe that while the conditioned media of activated T lymphocytes reduce the growth capacity of BTICs, this growth suppression was abrogated in live co-culture of BTICs with T cells. We present evidence that BTICs produce the extracellular matrix protein tenascin-C (TNC) to inhibit T cell activity in live co-culture. In human glioblastoma brain specimens, TNC was widely deposited in the vicinity of T cells. Mechanistically, TNC inhibited T cell proliferation through interaction with alpha5beta1 and alphavbeta6 integrins on T lymphocytes associated with reduced mTOR signaling. Strikingly, TNC was exported out of BTICs associated with exosomes, and TNC depleted exosomes suppressed T cell responses to a significantly lesser extent than control. Finally, we found that circulating exosomes from glioblastoma patients contained more TNC and T cell-suppressive activity than those from control individuals. Taken together, our study establishes a novel immunosuppressive role for TNC associated with BTIC-secreted exosomes to affect local and distal T lymphocyte immunity. PMID- 30288345 TI - Impact of chemotactic factors and receptors on the cancer immune infiltrate: a bioinformatics study revealing homogeneity and heterogeneity among patient cohorts. AB - Multiple soluble factors including proteins (in particular chemokines), non proteinaceous factors released by dead cells, as well as receptors for such factors (in particular chemokine receptors, formyl peptide receptors and purinergic receptors), influence the recruitment of distinct cell subsets into the tumor microenvironment. We performed an extensive bioinformatic analysis on tumor specimens from 5953 cancer patients to correlate the mRNA expression levels of chemotactic factors/receptors with the density of immune cell types infiltrating the malignant lesions. This meta-analysis, which included specimens from breast, colorectal, lung, ovary and head and neck carcinomas as well as melanomas, revealed that a subset of chemotactic factors/receptors exhibited a positive and reproducible correlation with several infiltrating cell types across various solid cancers, revealing a universal pattern of association. Hence, this meta-analysis distinguishes between homogeneous associations that occur across different cancer types and heterogeneous correlations, that are specific of one organ. Importantly, in four out of five breast cancer cohorts for which clinical data were available, the levels of expression of chemotactic factors/receptors that exhibited universal (rather than organ-specific) positive correlations with the immune infiltrate had a positive impact on the response to neoadjuvant chemotherapy. These results support the notion that general (rather than organ specific) rules governing the recruitment of immune cells into the tumor bed are particularly important in determining local immunosurveillance and response to therapy. PMID- 30288346 TI - Epigenetic treatment of multiple myeloma mediates tumor intrinsic and extrinsic immunomodulatory effects. AB - Immune evasion is an important driver of disease progression in the plasma cell malignancy multiple myeloma. Recent work highlights the potential of epigenetic modulating agents as tool to enhance anti-tumor immunity. The immune modulating effects of the combination of a DNA methyltransferase inhibitor and a histone deacetylase inhibitor in multiple myeloma is insufficiently characterized. Therefore, we used the murine immunocompetent 5T33MM model to investigate hallmarks of immunogenic cell death as well as alterations in the immune cell constitution in the bone marrow of diseased mice in response to the DNA methyltransferase inhibitor decitabine and the histone deacetylase inhibitor quisinostat. Vaccination of mice with 5T33 cells treated with epigenetic compounds delayed tumor development upon a subsequent tumor challenge. In vitro, epigenetic treatment induced ecto-calreticulin and CD47, as well as a type I interferon response. Moreover, treated 5T33vt cells triggered dendritic cell maturation. The combination of decitabine and quisinostat in vivo resulted in combinatory anti-myeloma effects. In vivo, epigenetic treatment increased tumoral ecto-calreticulin and decreased CD47 and PD-L1 expression, increased dendritic cell maturation and reduced CD11b positive cells. Moreover, epigenetic treatment induced a temporal increase in presence of CD8-positive and CD4-positive T cells with naive and memory-like phenotypes based on CD62L and CD44 expression levels, and reduced expression of exhaustion markers PD-1 and TIM3. In conclusion, a combination of a DNA methyltransferase inhibitor and a histone deacetylase inhibitor increased the immunogenicity of myeloma cells and altered the immune cell constitution in the bone marrow of myeloma-bearing mice. PMID- 30288348 TI - The prognostic and predictive value of IKZF1 and IKZF3 expression in T-cells in patients with multiple myeloma. AB - Purpose: While recent studies described the role of IKZF1/3 proteins in multiple myeloma (MM) cells, few have highlighted the significance of IKZF1/3 expression in T-cells. In this study we examine the prognostic and predictive value of IKZF1/3 expression in T-cells in patients with MM stage III. Experimental design: We analysed the IKZF1/3 expression levels in T-cells from 45 MM stage I (MMI) and 50 newly diagnosed MM stage III (MMIII) patients, according to Durie-Salmon staging system, by flow cytometry to examine their prognostic and predictive value. We also combined in vivo observations with in vitro assays to determine the effect of IKZF1/3 expression on the T-cell immunophenotype and anti-tumour T cell response in 162 MMIII patients. Results: We found that high IKZF3, but not IKZF1, expression in T-cells correlates with superior overall survival in MMIII patients treated with immunomodulatory drugs (thalidomide, lenalidomide and pomalidomide). Moreover, we show that higher IKZF3 expression in T-cells inhibits myeloma-specific T-cell response in vitro and that the immunophenotype of patients with high IKZF3 expression shows features that are contrary to the changes induced by immunomodulatory drugs. Although we observed higher IKZF3 expression levels in T-cells from patients with MMIII compared to MMI, IKZF3 expression was unaffected by the tumour microenvironment. Conclusion: In conclusion, IKZF3 expression in T-cells is a predictive value for clinical outcome in MMIII patients treated with immunomodulatory drugs due to its profound modulation of T-cell functionality. PMID- 30288347 TI - Combination with SGT-53 overcomes tumor resistance to a checkpoint inhibitor. AB - The tumor suppressor p53 responds to genotoxic and oncogenic stresses by inducing cell cycle arrest and apoptosis. Recent studies suggest that p53 also participates in the regulation of cellular immune responses. Here, we have investigated the potential of p53 gene therapy to augment immune checkpoint inhibition by combining an anti-programmed cell death protein 1 (PD1) antibody with SGT-53, our investigational nanomedicine carrying a plasmid encoding human wild-type p53. In three syngeneic mouse tumor models examined including a breast cancer, a non-small cell lung carcinoma, and a glioblastoma, SGT-53 sensitized otherwise refractory tumors to anti-PD1 antibody. The involvement of p53 in enhancing anti-PD1 immunotherapy appears to be multifaceted, since SGT-53 treatment increased tumor immunogenicity, enhanced both innate and adaptive immune responses, and reduced tumor-induced immunosuppression in a 4T1 breast tumor model. In addition, SGT-53 alleviates a fatal xenogeneic hypersensitivity associated with the anti-PD1 antibody in this model. Our data suggest that restoring p53 function by SGT-53 is able to boost anti-tumor immunity to augment anti-PD1 therapy by sensitizing tumors otherwise insensitive to anti-PD1 immunotherapy while reducing immune-related adverse events. PMID- 30288349 TI - Daratumumab induces CD38 internalization and impairs myeloma cell adhesion. AB - Daratumumab (Dara), a human immunoglobulin G1 kappa (IgG1kappa) monoclonal anti CD38 antibody, has been approved by the U.S. Food and Drug Administration for the treatment of relapsed multiple myeloma (MM) as a single agent as well as in combination with immunomodulatory drugs (IMiDs) and proteasome inhibitors (PI). Although the scientific rationale behind the use of Dara in combination with IMiDs has been extensively explored, the molecular mechanisms underlying Dara-PI regimens have not yet been investigated. Here, we demonstrate that CD38 on the surface of MM cells is rapidly internalized after Dara treatment; we also show that Dara treatment impairs MM cell adhesion, an effect that can be rescued by using the endocytosis inhibitor Dynasore. Finally, we show that Dara potentiates bortezomib (BTZ) killing of MM cells in vitro and in vivo, independent of its function as an immune activator. In conclusion, our data show that Dara impairs MM cell adhesion, which results in an increased sensitivity of MM to proteasome inhibition. PMID- 30288351 TI - Therapeutic vaccination with 4-1BB co-stimulation eradicates mouse acute myeloid leukemia. AB - Immunomodulatory therapies can effectively control haematological malignancies. Previously we reported the effectiveness of combination immunotherapies that centre on 4-1BB-targeted co-stimulation of CD8 + T cells, particularly when simultaneously harnessing the immune adjuvant properties of Natural Killer T (NKT) cells. The objective of this study was to assess the effectiveness of agonistic anti-4-1BB antibody-based combination therapy against two aggressive forms of acute myeloid leukemia (AML). Anti-4-1BB treatment alone resulted in transient suppression of established AML-ETO9a tumor growth in 50% of mice, however the majority of these mice subsequently succumbed to disease. Combining alpha-galactosylceramide (alpha-GalCer)-loaded tumor cell vaccination with anti-4 1BB antibody treatment increased the proportion of responding mice to 100%, and protection led to long-term, tumor-free survival, demonstrating complete eradication of AML. This finding was extended to established mixed lymphocytic leukemia (MLL)-AF9 tumors, whereby vaccine plus anti-4-1BB combination similarly resulted in 100% protection. The addition of anti-PD-1 to anti-4-1BB treatment, although improving survival outcomes compared to anti-4-1BB alone, was not as effective as NKT cell vaccination. The effectiveness of 4-1BB combination therapies was dependent on IFN-gamma signaling within host cells, but not tumors. Vaccine plus anti-4-1BB therapy elicited potent generation of functional effector and memory CD8 + T cells in all tumor-associated organs. Therapy induced KLRG1+ effector CD8 T cells were the most effective at controlling disease. We show that combining NKT cell-targeting vaccination with anti-4-1BB provides excellent therapeutic responses against AML and MLL in mice, and these results will guide ongoing efforts in finding immunotherapeutic solutions against acute myeloid leukemias. PMID- 30288350 TI - EBV infection determines the immune hallmarks of plasmablastic lymphoma. AB - Despite recent therapeutic progress, plasmablastic lymphoma (PBL), a distinct entity of high grade B cell lymphoma, is still an aggressive lymphoma with adverse prognosis. PBL commonly occurs in patients with HIV infection and PBL cells frequently express Epstein Barr virus (EBV) genome with type I latency. Occasionally however, PBL may develop in patients with an immunodepressed status without EBV and HIV infection. The aim of this study was to determine which PBL patients may benefit from the emerging strategies of immune checkpoint blockade. Here, we produced and analyzed the transcriptomic profiles of such tumors to address this question. Unsupervised hierarchical clustering analysis of PBL samples revealed they segregate according to their tumor EBV-status. Moreover, EBV+ PBL displays abundant leucocyte infiltrates and T-cell activation signatures, together with high expression levels of mRNA and protein markers of immune escape. This suggests that EBV infection induce an anti-viral cytotoxic immunity which progressively exhausts T lymphocytes and promotes the tolerogenic microenvironment of PBL. Hence, most EBV+ PBL patients presenting an early stage of cancer immune-editing process appear as the most eligible patients for immune checkpoint blockade therapies. PMID- 30288352 TI - Potent therapeutic efficacy of an alphavirus replicon DNA vaccine expressing human papilloma virus E6 and E7 antigens. AB - Cervical cancer develops as a result of infection with high-risk human papillomavirus (HPV) through persistent expression of early proteins E6 and E7. Our group pioneered a recombinant viral vector system based on Semliki Forest virus (SFV) for vaccination against cervical cancer. The most striking benefit of this alphavirus vector-based vaccine platform is its high potency. DNA vaccines on the other hand, have a major advantage with respect to ease of production. In this study, the benefits associated with both SFV-based vaccines and DNA vaccines were combined with the development of a DNA-launched RNA replicon (DREP) vaccine targeting cervical cancer. Using intradermal delivery followed by electroporation, we demonstrated that DREP encoding for E6,7 (DREP-E6,7) induced effective, therapeutic antitumor immunity. While immunizations with a conventional DNA vaccine did not prevent tumor outgrowth, immunization with a 200 fold lower equimolar dose of DREP (0.05 ug of DREP) resulted in approximately 85% of tumor-free mice. To overcome the safety concern of potential malignant transformation at the vaccination site, we evaluated the anti-tumor effect of a DREP vaccine encoding a shuffled version of E7 (DREP-E7sh). DREP-E7sh delayed tumor growth yet not to the same extent as DREP-E6,7. In addition, inclusion of a helper cassette and an ER targeting signal (sigHelp) did not significantly further enhance the suppression of tumor outgrowth in the long term, albeit exhibiting better tumor control early after immunization. Collectively, this study points towards the clinical evaluation of DREP encoding HPV antigens as a potent immunotherapy for patients with HPV16 (pre)-malignancies. PMID- 30288353 TI - MUC16 mutations improve patients' prognosis by enhancing the infiltration and antitumor immunity of cytotoxic T lymphocytes in the endometrial cancer microenvironment. AB - The incidence and mortality rates of endometrial cancer are increasing during recent years. CA125 (gene symbol MUC16) is a well-known diagnostic and prognostic serum marker of endometrial cancer. High serum CA125 level is associated with poor prognosis. MUC16 is one of the most frequently mutated genes in endometrial cancer. However, the potential relationship and underlying mechanism between MUC16 mutations and endometrial cancer patients' prognosis and disease progression remain unclear. In present study, we analyzed the whole exome sequencing data, RNA sequencing data and patients' clinical information in TCGA database and demonstrated that MUC16 mutational status was an independent prognostic factor for endometrial cancer patients. Patients with somatic MUC16 mutations had a prolonged overall survival time. MUC16 mutations promoted patients' antitumor immune responses. Cytotoxic immune cells mediated pathways were enriched in endometrial cancer samples with MUC16 mutations. Elevation of two pathways, NO2-dependent IL 12 pathway in NK cells and T cytotoxic cell surface molecules, significantly correlated with a higher rate of MUC16 mutations and a significantly favorable patients' prognosis. An increased level of cytotoxic T lymphocytes, not NK cells, infiltration was observed in the tumor microenvironment of patients with MUC16 mutations. High expression of molecular markers of T cells and CD8+ T cells associated with a higher rate of MUC16 mutations and a better patients' prognosis. These findings may provide deeper insight into potential endometrial cancer immunotherapy approaches. PMID- 30288354 TI - WEE1 kinase inhibition reverses G2/M cell cycle checkpoint activation to sensitize cancer cells to immunotherapy. AB - Intrinsic resistance to cytotoxic T-lymphocyte (CTL) killing limits responses to immune activating anti-cancer therapies. Here, we established that activation of the G2/M cell cycle checkpoint results in tumor cell cycle pause and protection from granzyme B-induced cell death. This was reversed with WEE1 kinase inhibition, leading to enhanced CTL killing of antigen-positive tumor cells. Similarly, but at a later time point, cell cycle pause following TNFalpha exposure was reversed with WEE1 kinase inhibition, leading to CTL transmembrane TNFalpha-dependent induction of apoptosis and necroptosis in bystander antigen negative tumor cells. Results were reproducible in models of oral cavity carcinoma, melanoma and colon adenocarcinoma harboring variable Tp53 genomic alterations. WEE1 kinase inhibition sensitized tumors to PD-1 mAb immune checkpoint blockade in vivo, resulting in CD8+-dependent rejection of established tumors harboring antigen-positive or mixed antigen-positive and negative tumor cells. Together, these data describe activation of the G2/M cell cycle checkpoint in response to early and late CTL products as a mechanism of resistance to CTL killing, and provide pre-clinical rationale for the clinical combination of agents that inhibit cell cycle checkpoints and activate anti-tumor immunity. PMID- 30288355 TI - Potentiating cancer vaccine efficacy in liver cancer. AB - Hepatocellular carcinoma (HCC) is the most common liver malignancy with a poor prognosis and an overall 5-year survival rate of approximately 5-6%. This is due because standard of care treatment options are limited and none of them shows a sufficient efficacy. HCC is an "inflammation-induced cancer" and preliminary preclinical and clinical data suggest that immunotherapeutic approaches may be a good alternative candidate for the treatment of HCC patients improving the dismal prognosis associated with this cancer. However, recent findings strongly suggest that an optimal immunotherapy in HCC requires the combination of an immune activator with immune modulators, aiming at compensating the strong liver immune suppressive microenvironment. One of the most promising strategy could be represented by the combination of a cancer vaccine with immunomodulatory drugs, such as chemotherapy and checkpoint inhibitors. Very limited examples of such combinatorial strategies have been evaluated in HCC to date, because HCC easily develops resistance to standard chemotherapy, which is also poorly tolerated by patients with liver cirrhosis. The present review describes the most update knowledge in this field. PMID- 30288357 TI - The comprehensive molecular landscape of the immunologic co-stimulator B7 and TNFR ligand receptor families in colorectal cancer: immunotherapeutic implications with microsatellite instability. AB - Immunotherapy is reportedly effective in a subset of colorectal cancers (CRCs) with high microsatellite instability (MSI-H). Exploring the expression patterns and clinical values of immunologic molecules is critical in defining the specific responsive candidates. Here, we performed comprehensive molecular profiling of the B7 and TNFR family genes across 6 CRC datasets with over 1,000 patients' details using cBioPortal TCGA data. About 20% of patients had B7 and TNFR family gene alterations. The frequency of B7 gene mutations (2.2%-5%) were similar to copy number alterations (0.53%-5.46%). TNFR amplifications were relatively more common (5.45-11.32%) than that of B7 (0.09-2.73%). B7 and TNFR gene mRNAs were upregulated in 26% of cases (102/379) and 16% of cases (61/379), respectively. The mRNA levels of B7 and TNFR genes were inversely correlated with promoter methylation status. Clinically, both B7-H3 and TNFSF7 mRNA overexpression were associated with unfavorable clinical outcomes, and the B7-H3 expression was increased gradually in cases with gene amplifications. Moreover, patients with MSI-H had significantly higher PD-L1 or PD-1 expression. Most importantly, in MSI H group, patients with PD-L1 or PD-1 upregulation had poorer survivals than those with PD-L1/PD-1 downregulation. This is the first study drawing the immune landscapes of the co-stimulator B7 and TNFR families in CRC and showing that MSI H patients with PD-1/PD-L1 upregulation are associated with poor clinical outcomes, providing potential markers to stratify patients responsive to immune checkpoint therapy. PMID- 30288356 TI - Ex vivo AKT-inhibition facilitates generation of polyfunctional stem cell memory like CD8+ T cells for adoptive immunotherapy. AB - Adoptive T cell therapy has shown clinical potential for patients with cancer, though effective treatment is dependent on longevity and potency of the exploited tumor-reactive T cells. Previously, we showed that ex vivo inhibition of AKT using the research compound Akt-inhibitor VIII retained differentiation and improved functionality of minor histocompatibility antigen (MiHA)-specific CD8+ T cells. Here, we compared a panel of clinically applicable AKT-inhibitors with an allosteric or adenosine triphosphate-competitive mode of action. We analyzed phenotype, functionality, metabolism and transcriptome of AKT-inhibited CD8+ T cells using different T cell activation models. Most inhibitors facilitated T cell expansion while preserving an early memory phenotype, reflected by maintenance of CD62L, CCR7 and CXCR4 expression. Moreover, transcriptome profiling revealed that AKT-inhibited CD8+ T cells clustered closely to naturally occurring stem cell-memory CD8+ T cells, while control T cells resembled effector memory T cells. Interestingly, AKT-inhibited CD8+ T cells showed enrichment of hypoxia-associated genes, which was consistent with enhanced glycolytic function. Notably, AKT-inhibition during MiHA-specific CD8+ T cell priming uncoupled preservation of early memory differentiation from ex vivo expansion. Furthermore, AKT-inhibited MiHA-specific CD8+ T cells showed increased polyfunctionality with co-secretion of IFN-gamma and IL-2 upon antigen recall. Together, these data demonstrate that AKT-inhibitors with different modality of action promote the ex vivo generation of stem cell memory-like CD8+ T cells with a unique metabolic profile and retained polyfunctionality. Akt-inhibitor VIII and GDC-0068 outperformed other inhibitors, and are therefore promising candidates for ex vivo generation of superior tumor-reactive T cells for adoptive immunotherapy in cancer patients. PMID- 30288358 TI - TGF-beta1 programmed myeloid-derived suppressor cells (MDSC) acquire immune stimulating and tumor killing activity capable of rejecting established tumors in combination with radiotherapy. AB - Cancer-induced myeloid-derived suppressor cells (MDSC) play an important role in tumor immune evasion. MDSC programming or polarization has been proposed as a strategy for leveraging the developmental plasticity of myeloid cells to reverse MDSC immune suppressive functions, or cause them to acquire anti-tumor activity. While MDSC derived ex vivo from murine bone marrow precursor cells with tumor conditioned medium efficiently suppressed T cell proliferation, MDSC derived from conditioned medium in presence of TGF-beta1 (TGFbeta-MDSC) acquired a novel immune-stimulatory phenotype, losing the ability to inhibit T cell proliferation and acquiring enhanced antigen-presenting capability. Altered immune function was associated with SMAD-2 dependent upregulation of maturation and costimulatory molecules, and downregulation of inducible nitric oxide synthase (iNOS), an effector mechanism of immunosuppression. TGFbeta-MDSC also upregulated FAS-ligand expression, leading to FAS-dependent killing of murine human papillomavirus (HPV) associated head and neck cancer cells and tumor spheroids in vitro and anti-tumor activity in vivo. Radiation upregulated FAS expression on tumor cells, and the combination of radiotherapy and intratumoral injection of TGFbeta-MDSC strongly enhanced class I expression on tumor cells and induction of HPV E7 tetramer positive CD8 + T cells, leading to clearance of established tumors and long-term survival. TGFbeta-MDSC derived from human PBMC with tumor conditioned medium also lost immunosuppressive function and acquired tumor-killing activity. Thus, TGFbeta1 mediated programming of nascent MDSC leads to a potent anti-tumor phenotype potentially suitable for adoptive immunotherapy. PMID- 30288359 TI - Formation and phenotypic characterization of CD49a, CD49b and CD103 expressing CD8 T cell populations in human metastatic melanoma. AB - Integrins alpha1beta1 (CD49a), alpha2beta1 (CD49b) and alphaEbeta7 (CD103) mediate retention of lymphocytes in peripheral tissues, and their expression is upregulated on tumor infiltrating lymphocytes (TIL) compared to circulating lymphocytes. Little is known about what induces expression of these retention integrins (RI) nor whether RI define subsets in the tumor microenvironment (TME) with a specific phenotype. Human metastatic melanoma-derived CD8 TIL could be grouped into five subpopulations based on RI expression patterns: RIneg, CD49a+ only, CD49a+CD49b+, CD49a+CD103+, or positive for all three RI. A significantly larger fraction of the CD49a+ only subpopulation expressed multiple effector cytokines, whereas CD49a+CD103+ and CD49a+CD49b+ cells expressed IFNgamma only. RIneg and CD49a+CD49b+CD103+ CD8 TIL subsets expressed significantly less effector cytokines overall. Interestingly, however, CD49a+CD49b+CD103+ CD8 expressed lowest CD127, and highest levels of perforin and exhaustion markers PD 1 and Tim3, suggesting selective exhaustion rather than conversion to memory. To gain insight into RI expression induction, normal donor PBMC were cultured with T cell receptor (TCR) stimulation and/or cytokines. TCR stimulation alone induced two RI+ cell populations: CD49a single positive and CD49a+CD49b+ cells. TNFalpha and IL-2 each were capable of inducing these populations. Addition of TGFbeta to TCR stimulation generated two additional populations; CD49a+CD49bnegCD103+ and CD49a+CD49b+CD103+. Taken together, our findings identify opportunities to modulate RI expression in the TME by cytokine therapies and to generate subsets with a specific RI repertoire in the interest of augmenting immune therapies for cancer or for modulating other immune-related diseases such as autoimmune diseases. PMID- 30288361 TI - Combination immune checkpoint blockade as an effective therapy for mesothelioma. AB - Mesothelioma is an aggressive asbestos induced cancer with extremely poor prognosis and limited treatment options. Immune checkpoint blockade (ICPB) has demonstrated effective therapy in melanoma and is now being applied to other cancers, including mesothelioma. However, the efficacy of ICPB and which immune checkpoint combinations constitute the best therapeutic option for mesothelioma have yet to be fully elucidated. Here, we used our well characterised mesothelioma tumour model to investigate the efficacy of different ICBP treatments to generate effective therapy for mesothelioma. We show that tumour resident regulatory T cell co-express high levels of CTLA-4, OX40 and GITR relative to T effector subsets and that these receptors are co-expressed on a large proportion of cells. Targeting any of CTLA-4, OX40 or GITR individually generated effective responses against mesothelioma. Furthermore, the combination of alphaCTLA-4 and alphaOX40 was synergistic, with an increase in complete tumour regressions from 20% to 80%. Other combinations did not synergise to enhance treatment outcomes. Finally, an early pattern in T cell response was predictive of response, with activation status and ICP receptor expression profile of T effector cells harvested from tumour and dLN correlating with response to immunotherapy. Taken together, these data demonstrate that combination ICPB can work synergistically to induce strong, durable immunity against mesothelioma in an animal model. PMID- 30288360 TI - IL-6 augments IL-4-induced polarization of primary human macrophages through synergy of STAT3, STAT6 and BATF transcription factors. AB - Macrophages in the tumor microenvironment respond to complex cytokine signals. How these responses shape the phenotype of tumor-associated macrophages (TAMs) is incompletely understood. Here we explored how cytokines of the tumor milieu, interleukin (IL)-6 and IL-4, interact to influence target gene expression in primary human monocyte-derived macrophages (hMDMs). We show that dual stimulation with IL-4 and IL-6 synergistically modified gene expression. Among the synergistically induced genes are several targets with known pro-tumorigenic properties, such as CC-chemokine ligand 18 (CCL18), transforming growth factor alpha (TGFA) or CD274 (programmed cell death 1 ligand 1 (PD-L1)). We found that transcription factors of the signal transducer and activator of transcription (STAT) family, STAT3 and STAT6 bind regulatory regions of synergistically induced genes in close vicinity. STAT3 and STAT6 co-binding further induces the basic leucine zipper ATF-like transcription factor (BATF), which participates in synergistic induction of target gene expression. Functional analyses revealed increased MCF-7 and MDA-MB 231 tumor cell motility in response to conditioned media from co-treated hMDMs compared to cells incubated with media from single cytokine-treated hMDMs. Flow cytometric analysis of T cell populations upon co culture with hMDMs polarized by different cytokines indicated that dual stimulation promoted immunosuppressive properties of hMDMs in a PD-L1-dependent manner. Analysis of clinical data revealed increased expression of BATF together with TAM markers in tumor stroma of breast cancer patients as compared to normal breast tissue stroma. Collectively, our findings suggest that IL-4 and IL-6 cooperate to alter the human macrophage transcriptome, endowing hMDMs with pro tumorigenic properties. PMID- 30288363 TI - Macrophages in radiation injury: a new therapeutic target. AB - Radiotherapy can induce toxicity in healthy tissues such as radiation-induced fibrosis (RIF), and macrophages are proposed as new profibrogenic cells. In this Point-of-View, we summarize the role of the immune response in ionizing radiation injury, and we focus on macrophages as a new therapeutic target in RIF. PMID- 30288362 TI - Prognostic role of pretreatment circulating MDSCs in patients with solid malignancies: A meta-analysis of 40 studies. AB - Myeloid-derived suppressor cells (MDSCs) have been shown to contribute to tumor progression, mainly through immune suppression. Inverse correlations have been observed between MDSC levels and patient survival for various malignancies. The purpose of this meta-analysis was to evaluate the prognostic value of pretreatment circulating MDSCs. We searched MEDLINE and EMBASE from their inceptions to September 2017 to identify relevant articles. Using a fixed or random effects model, pooled hazard ratios (HRs) were estimated for overall survival (OS) and combined disease-free survival, progression-free survival, and recurrence-free survival (DFS/PFS/RFS). A total of 40 studies comprising 2721 were included. For solid tumors, high levels of pretreatment circulating MDSCs were significantly associated with worse OS (HR = 1.796, 95% CI = 1.587-2.032) and DFS/PFS/RFS (HR = 2.459, 95% CI = 2.018-2.997). Breast cancer showed the largest association between high MDSC levels and worse OS (pooled HR = 3.053). Elevated MDSCs were also associated with worse OS for mixed-stage tumors (pooled HR = 1.659) and advanced-stage tumors (pooled HR = 2.337). Furthermore, both monocytic-MDSCs (M-MDSCs) and granulocytic or polymorphonuclear (PMN-MDSCs) showed negative associations with survival outcomes. Overall, high levels of pretreatment circulating MDSCs negatively influenced survival in most cancers. Pretreatment circulating MDSCs should be taken into account to further improve prognostic evaluation and develop novel therapeutic strategies. PMID- 30288364 TI - Smoker and non-smoker lung adenocarcinoma is characterized by distinct tumor immune microenvironments. AB - Tobacco smoking causes DNA damages in epithelial cells and immune dysfunction in the lung, which collectively contribute to lung carcinogenesis and progression. However, potential mechanisms by which tumor-infiltrating immune cells contribute to lung cancer survival and their differential contributions in ever-smokers and never-smokers are not well studied. Here, we performed integrative analysis of 11 lung cancer gene-expression datasets, including 1,111 lung adenocarcinomas and 200 adjacent normal lung samples. Distinct pathways were altered in lung carcinogenesis in ever-smokers and never-smokers. Never-smoker patients had a better outcome than ever-smoker patients. We characterized compositional patterns of 21 types of immune cells in lung adenocarcinomas and revealed the complex association between immune cell composition and clinical outcomes. Interestingly, we found two subsets of immune cells, mast cells and CD4+ memory T cells, which had completely opposite associations with outcomes in resting and activated status. We further discovered that several chemokines and their associated receptors (e.g., CXCL11-CX3CR1 axis) were selectively altered in lung tumors in response to cigarette smoking and their abundances showed stronger correlation with fractions of these immune subsets in ever-smokers than never-smokers. The status switched from the resting to activated forms in mast cells and CD4+ memory T cells might manifest some important processes induced by cigarette smoking during tumor development and progression. Our findings suggested that aberrant activation of mast cells and CD4+ memory T cells plays crucial roles in cigarette smoking-induced immune dysfunction in the lung, which contributes to tumor development and progression. PMID- 30288365 TI - Treatment-naive HPV+ head and neck cancers display a T-cell-inflamed phenotype distinct from their HPV- counterparts that has implications for immunotherapy. AB - Cancers progress when the immune system fails to identify and eliminate malignant cells. Recognition of this, combined with advances in tumor immunology, has allowed development of therapies that induce effective anti-tumor immune responses. For incompletely-understood reasons, effective responses to immunotherapy occur in some patients and not others. Head and neck squamous cell carcinomas (HNSCC) are a common cancer type that can be divided into two subsets based on human papillomavirus (HPV) status. HPV status is a strong predictor of positive clinical outcome. Expression of exogenous viral antigens by HPV+, but not HPV-, HNSCC allows direct comparison of the immune status (immune cell presence and characteristics) between these two otherwise anatomically-similar tumors. Using TCGA data, we compared the immune landscape between HPV+ and HPV- treatment-naive HNSCC. As compared to HPV- samples, HPV+ HNSCC exhibited a strong Th1 response characterized by increased infiltration with multiple types of immune cells and expression of their effector molecules. HPV+ HNSCC also expressed higher levels of CD39 and multiple T-cell exhaustion markers including LAG3, PD1, TIGIT, and TIM3 compared to HPV- HNSCC. Importantly, patients with higher expression of these exhaustion markers-indicative of a T-cell-inflamed tumor-correlated with markedly improved survival in HPV+, but not HPV-, HNSCC. Thus, profound differences exist between the immune landscape of HPV+ and HPV- HNSCC. These results suggest that immune checkpoint inhibitor therapy is a promising treatment strategy for HPV+ HNSCC, and that expression of immune checkpoint molecules could serve as a predictive biomarker of patient outcome in HPV+ HNSCC.

PMID- 30288366 TI - Black, White, and Gray: Macrophages in Skin Repair and Disease. AB - Purpose of Review: Macrophages alter their responses during the temporal stages of wound healing. During the inflammatory phase macrophages perform phagocytosis. During neovascularization macrophages activate angiogenesis. In the proliferation phase of wound healing, macrophages deposit extracellular matrix and during wound resolution macrophages phagocytize excessive cellular components. This review addresses how these changing phenotypes affect skin repair and disease. Recent Findings: Macrophages can determine the outcome of repair and can shift the normal wound healing response into fibrosis or chronic wounds. Emerging single cell technologies for the first time provide us with tools to uncover macrophage origin, heterogeneity and function. Summary: Macrophages may exist as one population where all cells alter their phenotype in response to signals from the microenvironment. Alternatively, macrophages may exist as distinct subsets that can control wound outcomes. A clarified understanding will strengthen our knowledge of skin biology and aid in the development of wound healing therapies. PMID- 30288368 TI - Melanoma Cell Death Mechanisms. AB - Over recent years, several new molecular and immunogenic therapeutic approaches to melanoma treatment have been approved and implemented in clinical practice. Mechanisms of resistance to these new therapies have become a major problem. Mutation-specific pharmacotherapy can result in simultaneous emergence of resistant clones at many separate body sites despite an initially positive therapeutic response. Additionally, treatments aimed at inducing apoptosis are subject to resistance due to escape through other known mechanisms of regulated cell death (RCD). In this review, we discuss the complexity in pharmacological manipulation of melanoma with c-Kit, BRAF, MEK, and/or mTOR mutant cell lines. This study also addresses melanoma evasion of cell death through modalities of RCD such as apoptosis, autophagy, and necroptosis. This study also examines new combination therapies which have been approved to target both cell cycle dysregulation and cell death pathways. Lastly, we recognize the importance of immunomodulation though manipulation of the body's natural killing mechanisms with CTLA4, PD1, and CSF1 inhibition. As we begin to recognize tumor cell activation of alternate pathways, evasion of programmed cell death, and manipulation of the tumor microenvironment, it is increasingly important to grasp the complexity of personalized therapy in melanoma treatment. PMID- 30288369 TI - Role of PET/CT in the Evaluation of Aortic Disease. AB - Positron emission tomography (PET) /computed tomography (CT) has been established as a standard imaging modality in the evaluation of malignancy. Although PET/CT has played a major role in the management of oncology patients, its clinical use has also increased for various disorders other than malignancy. Growing evidence shows that PET/CT images have many advantages in aortic disease as well. This review article addresses the potential role of PET/CT in diseases involving the aorta, emphasizing its usefulness with regard to acute thoracic aortic syndromes, aortic aneurysm, atherosclerotic lesions, aortitis and aortic tumors. PMID- 30288370 TI - Use of Combined Oral Contraceptives in Perimenopausal Women. AB - While perimenopausal women have low fecundity, they are still capable of becoming pregnant and the majority of pregnancies occurring during perimenopause are unintended pregnancies. Therefore, even during perimenopause, contraception must be used if unintended pregnancies are to be avoided. However, many perimenopausal women and healthcare providers believe that older people should not take combined oral contraceptives (COC) because doing so may be dangerous. However, to date, there is no evidence that taking COC presents an increased risk of cardiovascular events or breast cancer for middle-aged women as compared to other age groups, and in their recommendations, the Centers for Disease Control and Prevention (CDC) also do not list age itself as a contraindication for COC. Perimenopausal women often experience menstrual irregularity, heavy menstrual bleeding, and vasomotor symptoms. Taking COCs can help control these symptoms and significantly reduce the risk of ovarian cancer, endometrial cancer, and colorectal cancer. The objective of the present review is to examine the usage methods of COC among perimenopausal women and the health issues that may arise from taking COC in perimenopausal women. PMID- 30288371 TI - Effects of NADPH Oxidase Inhibitors and Mitochondria-Targeted Antioxidants on Amyloid beta1-42-Induced Neuronal Deaths in Mouse Mixed Cortical Cultures. AB - The Amyloid beta peptide (Abeta) is a main component of senile plaques in Alzheimer's disease. Currently, NADPH oxidase (NOX) and mitochondria are considered as primary sources of ROS induced by Abeta. However, the contribution of NOX and mitochondria to Abeta-induced ROS generation has not been well defined. To delineate the relative involvement of NOX and mitochondria in Abeta induced ROS generation and neuronal death in mouse cortical cultures, we examined the effect of NOX inhibitors, apocynin and AEBSF, and the mitochondria-targeted antioxidants (MTAs), mitotempol and mitoquinone, on Abeta-induced ROS generation and neuronal deaths. Cell death was assessed by measuring lactate dehydrogenase efflux in bathing media at 24 and 48 hrs after exposure to Abeta1-42. Abeta1-42 induced dose- and time-dependent neuronal deaths in cortical cultures. Treatment with 20 uM Abeta1-42 markedly and continuously increased not only the DHE fluorescence (intracellular ROS signal), but also the DHR123 fluorescence (mitochondrial ROS signal) up to 8 hrs. Treatment with apocynin or AEBSF selectively suppressed the increase in DHE fluorescence, while treatment with mitotempol selectively suppressed the increase in DHR123 fluorescence. Each treatment with apocynin, AEBSF, mitotempol or mitoquinone significantly attenuated the Abeta1-42-induced neuronal deaths. However, any combined treatment with apocynin/AEBSF and mitotempol/mitoquinone failed to show additive effects. These findings indicate that 20 uM Abeta1-42 induces oxidative neuronal death via inducing mitochondrial ROS as well as NOX activation in mixed cortical cultures, but combined suppression of intracellular and mitochondrial ROS generation fail to show any additive neuroprotective effects against Abeta neurotoxicity. PMID- 30288372 TI - Effects of Ivabradine on Left Ventricular Systolic Function and Cardiac Fibrosis in Rat Myocardial Ischemia-Reperfusion Model. AB - We evaluated the effects of Ivabradine on left ventricle (LV) ejection fraction (EF) and LV infarcted tissue in the rat myocardial ischemia-reperfusion model. Twenty rats were randomly assigned to group 1 (ischemia-reperfusion, no treatment, n=10) and group 2 (ischemia-reperfusion + Ivabradine 10 mg/kg, n=10). Ivabradine was administered for 28 days. Echocardiography was performed at 7 days and at 28 days after the induction of ischemia-reperfusion injury. Cardiac fibrosis induced by ischemia-reperfusion injury was evaluated by Masson's trichrome staining. The infarct size was quantified using the Image J program. At the 28-day follow-up, LVEF was significantly higher (36.02+/-6.16% vs. 45.72+/ 2.62%, p<0.001) and fractional shortening was significantly higher (15.23+/-2.84% vs. 20.13+/-1.38%, p<0.001) in group 2 than group 1. Delta (28 day minus 7 day) EF was significantly higher in group 2 than group 1 (-4.36+/-3.49% vs. 4.31+/ 5.63%, p<0.001). Also, heart rate (beats/min) was significantly lower in group 2 than group 1 (251.67+/-25.19 vs. 199.29+/-31.33, p=0.025). Group 2 had a smaller infarct size (40.70+/-8.94% vs. 30.19+/-5.89%, p<0.01) than group 1 at 28-day follow-up. Oral administration of Ivabradine could improve LV systolic function and reduce infarcted tissue area in rat myocardial ischemia-reperfusion model. PMID- 30288373 TI - The Predictive Value of Epstein-Barr Virus-Positivity in Patients Undergoing Gastrectomy Followed by Adjuvant Chemotherapy. AB - The present study evaluated the survival impact of standard adjuvant chemotherapy and prognostic differences between Epstein-Barr virus (EBV)-associated gastric cancer (EBVaGC) and EBV-negative gastric cancer (EBVnGC). A total of 276 patients were enrolled according to the following criteria: 1) pathologically diagnosed with primary gastric adenocarcinoma, 2) test results from EBV-encoded RNA in situ hybridization, 3) stage II/III according to the 7th edition of UICC/AJCC staging system for gastric cancer, and 4) postoperative adjuvant chemotherapy. Fifty-nine (21.4%) and 217 (78.6%) patients exhibited EBVaGC and EBVnGC, respectively, while 129 (46.7%) patients were classified as stage II and 147 (53.3%) as stage III. As for adjuvant chemotherapy, 87 (31.5%) patients received capecitabine and oxaliplatin, while 189 (68.5%) received S-1 monotherapy. With a median follow-up duration of 21.3 (6.4-89.0) months, the estimated 3-year disease-free survival (DFS) and overall survival (OS) rates were 74.8% and 83.0%, respectively. In univariate analysis and multivariate analysis using a Cox proportional hazard model including age, gender, stage, Lauren classification, and the type of chemotherapy, EBV-positivity was not significantly associated with DFS (p-value= 0.630) regardless of the type of chemotherapy. Therefore, no association was found between EBV positivity and the survival outcomes in patients with curatively resected gastric cancer who received standard adjuvant chemotherapy. PMID- 30288374 TI - Association of Coffee and Tea with Ferritin: Data from the Korean National Health and Nutrition Examination Survey (IV and V). AB - There have been few studies that have evaluated the association between coffee intake and iron in Korean population. Data from the Korean National Health and Nutrition Examination Survey (IV and V; 2007-2012) was used to investigate the association between coffee and green tea intake and serum ferritin levels in Korean adults. Beverage intake was assessed using a food frequency questionnaire. Multivariate linear regression was performed to evaluate the relationship between coffee and tea intake and serum ferritin levels, after adjusting for age, body mass index, education level, smoking status, alcohol consumption, physical activity, hypertension, diabetes mellitus, and daily iron intake. Coffee intake was negatively related to serum ferritin levels in both sexes. The multivariate adjusted geometric mean of serum ferritin level was 100.7 ng/mL (95% confidence interval [CI]: 98.2-103.4) in men drinking <1 coffee/day, and 92.2 ng/mL (95% CI: 89.7-94.8) in those drinking >=3 coffees/day. In women, the equivalent serum ferritin levels were 35.6 ng/mL (95% CI: 34.8-36.4) and 28.9 ng/mL (95% CI: 27.8 30.1). However, green tea intake was not related to serum ferritin levels. In conclusion, coffee consumption was associated with lower serum ferritin levels in Korean adults. PMID- 30288377 TI - An Unusual Adult Complex Congenital Heart Disease. PMID- 30288375 TI - Association between Smoking and Unintentional Injuries among Korean Adults. AB - Using a cross-sectional representative national survey, we evaluated the relationship between cigarette smoking and unintentional injuries among Korean adults. We used data from the 2009 Korean Community Health Survey. Smoking status was defined as never smokers, ex-smokers, and current smokers. Current smokers were categorized into light daily smokers (1-10 cigarettes/day), moderate daily smokers (11-20 cigarettes/day), or heavy daily smokers (>=21 cigarettes/day). We used the Poisson regression model with a robust variance estimation to estimate prevalence rate ratios (PRR) and corresponding 95% confidence interval (95% CI). After adjusting for demographic characteristics, socioeconomic variables, lifestyle variables, and health status variables, former smokers (PRR, 1.19, 95% CI 1.11-1.28), light daily smokers (PRR 1.22, 95% CI 1.13-1.32), moderate daily smokers (PRR 1.33, 95% CI 1.24-1.42), and heavy daily smokers (PRR 1.40, 95% CI 1.25-1.57) had an increased risk for unintentional injuries compared with non smokers. In conclusion, cigarette smoking is associated with unintentional injuries in a dose-response manner in Korean adults. The findings suggest that community smoking cessation programs may reduce morbidity and mortality from unintentional injuries.

PMID- 30288376 TI - Predictors of Clinical Outcome in Patients with Angiographically Intermediate Lesions with Minimum Lumen Area Less than 4 mm2 Using Intravascular Ultrasound in Non-Proximal Epicardial Coronary Artery. AB - We investigated predictors of major adverse cardiac events (MACE) with two years after medical treatment for lesions with angiographically intermediate lesions with intravascular ultrasound (IVUS) minimum lumen area (MLA) <4 mm2 in non proximal epicardial coronary artery. We retrospectively enrolled 104 patients (57 males, 62+/-10 years) with angiographically intermediate lesions (diameter stenosis 30-70%) with IVUS MLA <4 mm2 in the non-proximal epicardial coronary artery with a reference lumen diameter between 2.25 and 3.0 mm. We evaluated the incidences of major adverse cardiovascular events (MACE including death, myocardial infarction, target lesion and target vessel revascularizations, and cerebrovascular accident) two years after medical therapy. During the two-year follow-up, 15 MACEs (14.4%) (including 1 death, 2 myocardial infarctions, 10 target vessel revascularizations, and 2 cerebrovascular accidents) occurred. Diabetes mellitus was more prevalent (46.7% vs. 18.0%, p=0.013) and statins were used less frequently in patients with MACE compared with those without MACE (40.0% vs. 71.9%, p=0.015). Independent predictors of MACEs with two years included diabetes mellitus (odds ratio [OR]=3.41; 95% CI=1.43-8.39, p=0.020) and non-statin therapy (OR=3.11; 95% CI=1.14-6.50, p=0.027). Long-term event rates are relatively low with only medical therapy without any intervention, so the cut off of IVUS MLA 4 mm2 might be too large to be applied for defining significant stenosis. The predictors of long-term MACE were diabetes mellitus and statin therapy in patients with angiographically intermediate lesions in non-proximal epicardial coronary artery. PMID- 30288379 TI - Minimal Change Disease Associated with Ingestion of Poison Sumac. PMID- 30288381 TI - The impact of diabetes mellitus on quality of life - differences between genders. AB - Objective: To determine whether there are gender differences in the impact of the disease in the quality of life of individuals with Diabetes Mellitus type 2. Methods: The sample consisted of 192 individuals distributed in equal numbers by gender. Data were collected between the months of August 2013 to May 2014, by sociodemographic and clinical questionnaires and instruments for assessing quality of life (PAID) and adherence to treatment. Results: The age of the patients ranged from 30 to 80 years old with a mean of 61 years of age (+/- 11). B-PAID scores were higher in men except in issues related to social support, but the differences were not statistically significant; 51.7% of the patients with good adherence to treatment were women and 48.3% were men. Conclusions: The perception of the impact of diabetes in the quality of life of individuals in the present study, measured by the B-PAID instrument, showed that the highest scores predominate in men, that is, they have a higher degree of emotional distress than women. In the group with good adherence to treatment, there is a greater number of individuals with higher PAID scores, especially in men. In the group with poor adherence to treatment, the number of individuals with a high degree of emotional distress was similar in both sexes. This research was approved by the Research Ethics Committee of UNIFESP, through Plataforma Brasil (Protocol number 103,384). PMID- 30288380 TI - Genotype and phenotype of salt-stimulated paraoxonase 1 (PON1) is associated with atherogenic indices in type 2 diabetes. AB - Background: Paraoxonase 1 (PON1) and lipid abnormalities contribute to the development of cardiovascular disease, which is the principal cause of mortality in patients with type 2 diabetes (T2D). Data are not available on the potential association between salt-stimulated activity of PON1 (PON1-salt) and the atherogenic indices in T2D, therefore, we focused on these associations and evaluated whether the functional variants PON1-Q192R and PON1-L55M influence the associations. Methods: Paraoxonase activity (PON1-para), arylesterase activity (PON1-aryl) and salt-stimulated activity (PON1-salt) were measured by spectrophotometric assays. The atherogenic index of plasma (AIP) was calculated from the log (TG/HDL-C). The genetic analyses were made by the restricted fragment length polymorphism after PCR amplification. Results: We observed that PON1-salt was negatively correlated with total cholesterol (TC)/HDL-C (r = 0.441,p = 0.006), LDL-C/HDL-C (r = -0.415, p = 0.011), and AIP (r = -0.422, p = 0.009). Correlations between PON1-salt and all three atherogenic indices were significantly affected by PON1-L55M and PON1-Q192R. Linear regression showed that AIP (p = 0.002), LDL-C/HDL-C (p = 0.005), and TC/HDL-C (p = 0.002) were independently associated with PON1-salt. Based on Ridge regression, the standardized coefficients -0.358, -0.297, and - 0.044 were obtained for AIP, LDL C/HDL-C, and TC/HDL-C, respectively, and this shows that AIP could have more negative effect on PON1-salt than the others. Conclusions: The decreased PON1 salt may be considered as a risk factor for atherosclerosis in T2D, therefore, understanding the associations between PON1-salt as an important although neglected property and atherogenic indices may be valuable in T2D. Accordingly, detection of PON1-salt status (phenotype and genotype) together with the atherogenic indices particularly AIP could be beneficial in identifying the increased atherogenicity in T2D. PMID- 30288382 TI - Circulating tumor DNA (ctDNA) in the era of personalized cancer therapy. AB - The heterogeneity of tumor is considered as a major difficulty to victorious personalized cancer medicine. There is an extremeneed of consistent response evaluation for in vivo tumor heterogeneity anditscoupledconflict mechanisms. In this occasion researchers will be able to keep pace withpredictive, preventive, personalized, and Participatory (P4) medicine for cancer managements. In fact tumor heterogeneity is a central part of cancer evolution,soin order to progress in understanding of the dynamics within a tumor some diagnostic apparatus should be improved. Latest molecular techniques like Next generation Sequencing (NGS) and ultra-deep sequencing could disclose some clones within a liquid tumor biopsy which mainly responsible of treatment resistance. Circulating tumor DNA (ctDNA) as a main component of liquid biopsy is agifted biomarker for cancer mutation tracking as well as profiling. Personalized medicine facilitate learning regarding to genetic pools of tumor and their possible respond to treatment which could be much easier by using of ctDNA.With this information, cliniciansarelooking forward to find the best strategies for prevention, screening, and treatment in the way of precision medicine. Currently, numerous clinical efficacy of such informative improved treatment are in hand. Here we represent the review of plasma-derived ctDNA studies use in personalized cancer managements.

AB - Background: The present study describes the development and identity phases of a teleophthalmology system used for screening of diabetic retinopathy. Methods: A questionnaire was used to identify the main factors necessary for diagnosis of diabetic retinopathy and the features required for a teleophthalmology system. In the second phase, a web-based prototype of the system was designed using the data collected in the previous phase. In the final phase, the system was optimized based on the users' ideas and comments; then, it was evaluated through a standard usability testing questionnaire. Results: The results showed that the lowest average percentages were related to ethnicity (61%), optometrist's office address (61%), and consultant physician's office address (65%). A web-based prototype was designed using the Visual Studio and Dreamweaver programming tools. This system comprised patient identity data, medical history, clinical data, and retinal images of the patient. The mean score of usability testing and user satisfaction including specialists, residents, and optometrist was 7.3, 7.1 and 7.3 (out of a total 9), respectively. The evaluation results revealed that the system was classified as good. Conclusion: The telescreening system suggested in the current study could be helpful in timely diagnosis. Moreover, it would reduce the treatment costs and complexities. Regardless of the positive points of telemedicine systems, one of the most challenges in this study was the Internet infrastructure to design and apply the system. The future studies, therefore, could focus on the application of cell phone technology for rendering teleophthalmology.

PMID- 30288385 TI - Obesity paradox on the survival of elderly patients with diabetes: an AHAP-based study. AB - Background and objectives: Overweight and obesity are among the important challenges in health issues and survival of elderly people. The current study aimed to evaluate the survival rate of elderly patients with diabetes, and its influencing factors, on the basis of body mass index (BMI). Methods and materials: The design of the current study was based on the Amirkola Health and Aging Project (AHAP) cohort. The 5-year survival rate of elderly people with diabetes and the factors that influence the mortality rate by Cox regression model were analyzed. Results: Out of 1616 elderly people who were evaluated in the current study, 501 (31%) had diabetes. The results showed that diabetes significantly increased the mortality rate (adjusted hazard ratio [HR] = 2.10; 95% confidence interval [CI]: 1.57-2.81; P < 0.001). Furthermore, overweight (HR = 0.41; 95%CI: 0.24-0.75; P = 0.002), obesity (HR = 0.30; 95% CI: 0.41-0.63; P = 0.002), history of diabetes (HR = 0.56; 95%CI: 0.34-0.93; P = 0.024), moderate and high physical activity level (HR = 0.36; 95%CI: 0.13-0.99; P = 0.049) decreased the risk of mortality and central obesity (HR = 1.76; 95% CI: 1.01 3.11; P = 0.049), fasting blood sugar >=200 (HR = 2.46; 95% CI: 1.46-4.15; P < 0.001), brain stroke, and neurological diseases (HR = 3.12; 95% CI: 1.78-5.49; P < 0.001) increased the risk of mortality. Conclusion: Although overweight and obesity significantly improved the risk of mortality in elderly patients with diabetes, central obesity is still considered as an important risk factor. PMID- 30288386 TI - Is there a relationship between body mass index and diabetic retinopathy in type II diabetic patients? A cross sectional study. AB - Background: Type 2 diabetes mellitus (T2DM) is one of the most important leading causes of disability, premature mortality and Diabetic Retinopathy (DR) that is one of the diabetes-related complications in diabetic patients and the most common cause of vision loss in diabetic patients. The aim of the study was to evaluate the association between DR and body mass index (BMI) in those patients with T2DM. Methods: This was a central-based, cross-sectional study on 518 diabetic patients. Their medical history and the laboratory data were collected. All the patients received examination of diabetic retinopathy by professional ophthalmologist. Based on their optic fundi findings, they were classified into five groups: No retinopathy, Mild Non-proliferative Diabetic Retinopathy (NPDR), Moderate NPDR, Severe NPDR, Proliferative diabetic retinopathy (PDR). To analysis data SPSS v18 software used. Frequency, percent, mean and standard deviation were used for population description. t test, spearman correlation, partial correlation, analysis of variance (ANOVA) and Chi-square test (chi2) were used for analytic analysis. Multivariate logistic regression was used to estimate the odds ratio. Results: 518 patients with T2DM 198 male (38%), 320 female (62%) included in this study. The mean age of patients was 61.02 +/- 10.18 years. The mean age at onset was 49.06 + 10.52 years and the mean duration of diabetes was 12.09 +/- 7.81 years. There was a strong relationship between duration of diabetes and DR (P = 0.001). There were strong significant association between the development of DR and Insulin therapy (OR = 5.975). Correlation analysis between Retinopathy and BMI showed that BMI had inverse relationship with DR when BMI considered as a continuous variable (p-value = 0.009 and correlation coefficient = -0.467). Conclusion: BMI in diabetic patient is one of the most important clinical parameter for their health and disease progression. We conclude that BMI had inverse relationship with DR when BMI considered as a continuous variable. PMID- 30288387 TI - Association of serum uric acid with nephropathy in Iranian type 2 diabetic patients. AB - Background: Diabetic nephropathy (DN) is the major cause of end-stage renal disease. Recent studies suggest that it is probable that uric acid is involved in the pathogenesis of diabetic nephropathy. This study aim was to investigate the association between serum uric acid and kidney function in Iranian patients with type 2 diabetes mellitus. Methods: In this case-control study, a total of 201 diabetic patients with or without impaired kidney function (glomerular filtration rate/GFR < 60 and GFR >= 60) were selected. In both groups, serum fasting glucose (FBS), HbA1c, urea, creatinine, uric acid and lipid profile, urine albumin and GFR were measured and results were compared between the two groups. The results also categorized into three groups based on uric acid tertiles. Results: Serum levels of uric acid, urea and creatinine as well as urine albumin/creatinine ratio (ACR) were significantly different between the two groups. GFR, creatinine and also urea were significantly different between uric acid tertiles (p < 0.05). Conclusions: Serum uric acid is associated with decreased GFR as well as albuminuria and can be used as an indicator of DN. PMID- 30288388 TI - TLR4/MyD88 -mediated CCL2 production by lipopolysaccharide (endotoxin): Implications for metabolic inflammation. AB - Background: Obese human and mice were reported to have higher circularity endotoxin (LPS) levels as compared to their lean counter parts. The current study was aimed to reveal the molecular mechanisms underlying the LPS mediated induction of CCL2 in human monocytes/macrophages. Methods: Human monocytic cell line THP-1, THP-1 cells derived macrophages and primary macrophages were treated with LPS and TNF-alpha (positive control). CCL2 expression was determined with real-time RT-PCR and ELISA. THP-1-XBlueTM cells, THP-1-XBlueTM-defMyD cells, TLR4 neutralization antibody, TLR4 siRNA and inhibitors for NF-kB and MAPK were used to study the signaling pathways. Phosphorylation of NF-kB and c-Jun was analyzed by ELISA. Results: LPS upregulates CCL2 expression at both mRNA (THP-1: 23.40 +/- .071 Fold, P < 0.0001; THP-1-derived macrophages: 103 +/- 0.56 Fold, < 0.0001; Primary macrophages: 48 +/- 1.41 Fold, P < 0.0005) and protein (THP1 monocytes:1048 +/- 5.67 pg/ml, P < 0.0001; THP-1-derived macrophages; 2014 +/- 2.12, P = 0.0001; Primary macrophages: 859.5 +/- 3.54, P < 0.0001) levels in human monocytic cells/macrophages. Neutralization of TLR4 blocked LPS-induced CCL 2 secretion (P < 0.0001). Silencing of TLR4 by siRNA also significantly reduced LPS-induced CCL-2 production. Furthermore, MyD88-Knockout cells treated with LPS did not produce CCL-2. NF-kB and c-Jun phosphorylation was noted in LPS treated cells. Conclusion: Overall, our data reveal that LPS induces CCL-2 in monocytes/macrophages via TLR4/MyD88 signaling which leads to the activation of NF-kB/AP-1 transcription factors. PMID- 30288390 TI - Operative Treatment of Proximal Rectus Femoris Injuries in Professional Soccer Players: A Series of 19 Cases. AB - Background: Proximal rectus femoris (PRF) tears are relatively rare injuries among top-level athletes. PRF injuries can be avulsions of both tendon heads (direct and reflected heads) or of a single head, and some have a tendency to progress to recurrent injuries. Purpose: To describe a series of operatively treated PRF ruptures in professional soccer players. Study Design: Case series; Level of evidence, 4. Methods: Nineteen cases of PRF injuries (18 patients, 1 bilateral) in professional soccer players who were treated surgically were retrospectively reviewed. Perioperative findings with return-to-play data were recorded. Results: Of the PRF injuries, 10 total avulsions (both heads) and 9 single-head tears were seen on magnetic resonance imaging and were later confirmed during surgery. All 18 patients returned to their preinjury level of play (mean follow-up, 2.8 years [range, 1-11 years]). Conclusion: The repair of PRF tears in professional soccer players yielded good results and allowed all patients to return to their preinjury level of play. PMID- 30288389 TI - Colony-stimulating factors detected in tumor cells and voided urine are potential prognostic markers for patients with muscle-invasive bladder cancer undergoing radical cystectomy. AB - Background: The clinical use of macrophage colony-stimulating factor, granulocyte colony-stimulating factor (G-CSF), and granulocyte macrophage colony-stimulating factor (GM-CSF) has improved the safety of cytotoxic chemotherapy. However, the overexpression of these CSFs in cancers has been reported to be associated with a poor prognosis in various malignancies. We evaluated the potential of CSF expression as a predictor of clinical outcome in patients with muscle-invasive bladder cancer (MIBC). Methods: Consecutive patients (n=58) with MIBC who underwent radical cystectomy (RC) were included in this retrospective study. Treatment-naive tumor specimens obtained by initial transurethral resection of bladder tumors prior to RC were immunostained with antibodies against macrophage colony-stimulating factor, G-CSF, and GM-CSF. We compared the clinicopathological variables and survival between these groups. Baseline levels of CSFs in the serum and voided urine were quantified using an enzyme-linked immunosorbent assay and compared with the expression of CSFs in the tumor lesions. Results: Low expression of GM-CSF in the tumor cells was significantly correlated with a pathological T4 category (vs T2-3; P=0.02). In univariate survival analysis, high G-CSF and low GM-CSF expression in the tumor lesion were associated with poor outcomes. Furthermore, Cox proportional regression analysis revealed that high G CSF and low GM-CSF expression in the tumor were independent predictors of shorter recurrence-free survival, cancer-specific survival, and overall survival. The levels of CSFs in voided urine were associated with the expression of CSFs in the tumor lesions. Conclusion: GM-CSF and G-CSF expression in the tumor lesions obtained by initial transurethral resection are independent predictors of poor outcome in MIBC after RC. Levels of G-CSF and GM-CSF in urine before treatment could be useful in prognostication. PMID- 30288391 TI - Athletic Hip Injuries in Major League Baseball Pitchers Associated With Ulnar Collateral Ligament Tears. AB - Background: Ulnar collateral ligament (UCL) reconstruction is a reliable treatment for elite overhand throwers with UCL tears. In recent years, this procedure has become increasingly common among Major League Baseball (MLB) pitchers. Predisposing factors and associated comorbidities, however, have not been fully elucidated. Purpose/Hypothesis: The purpose of this study was to determine whether professional baseball pitchers who underwent UCL reconstruction had an increased incidence of hip or groin injuries 4 years before or after surgery. We hypothesized that MLB pitchers who sustain hip or groin injuries may be more likely to develop UCL tears because of alterations and overcompensation in the kinetic chain during overhand throwing. Study Design: Cohort study; Level of evidence, 3. Methods: A comprehensive list of all 247 MLB players who underwent UCL reconstruction between 2005 and 2017 was created using publicly accessible online data. The application of inclusion criteria yielded a final sample size of 145 athletes. These athletes' injury histories were identified and cross-referenced with the official MLB disabled list. Matched controls were generated for a comparison of results. Results: Of the 145 MLB pitchers who underwent UCL reconstruction between 2005 and 2017, 40 (27.6%) endured a proximal lower extremity injury within 4 years of their surgery. Specifically, 16 pitchers sustained hip injuries, 13 suffered hamstring injuries, and 14 experienced groin injuries. A significantly lower rate of hip- and groin-related injuries (17.9%) was identified in matched controls during a similar time frame (P = .049). Conclusion: The results of this study demonstrate that MLB pitchers who required UCL reconstruction sustained a higher frequency of proximal lower extremity injuries both before and after surgery compared with matched controls. This finding is significant as the treatment of antecedent hip lesions, as well as an emphasis on hip and core muscle mobility and strengthening, may help reduce injuries to the UCL. PMID- 30288392 TI - Using a Positive Deviance Approach to Influence the Culture of Patient Safety Related to Infection Prevention. AB - Background: Health care-associated infections (HAIs) are a socio-technical problem. We evaluated the impact of a social change intervention on health care personnel (HCP), called "positive deviance" (PD), on patient safety culture related to infection prevention among HCP. Methods: This observational study was done in 6 medical wards at an 800-bed public academic hospital in the United States. Three of these wards were randomly assigned to receive PD intervention on HCP. After a retrospective 6-month baseline period, PD was implemented over 9 months, followed by 9 months of follow-up. Patient safety culture and social networks among HCP were surveyed at 6, 15, and 24 months. Rates of HAI were measured among patients. Results: The measured patient safety culture was steady over time at 69% aggregate percent positive responses in wards with PD vs decline from 79% to 75% in wards without PD (F statistic 10.55; P = .005). Social network maps suggested that nurses, charge nurses, medical assistants, ward managers, and ward clerks play a key role in preventing infections. Fitted time series of monthly HAI rates showed a decrease from 4.8 to 2.8 per 1000 patient-days (95% confidence interval [CI], 2.1 to 3.5) in wards without PD, and 5.0 to 2.1 per 1000 patient-days (95% CI, -0.4 to 4.5) in wards with PD. Conclusions: A positive deviance approach appeared to have a significant impact on patient safety culture among HCP who received the intervention. Social network analysis identified HCP who are likely to help disseminate infection prevention information. Systemwide interventions independent of PD resulted in HAI reduction in both intervention and control wards. PMID- 30288394 TI - Newborn With Enlarged Erythematous Mass on Back: Case Report and Review of Medical Literature. AB - Newborn skin nodules are usually benign and self-resolving skin condition. Differential diagnosis of such lesions include cysts, hemangioma, abscess, cellulitis, sclerema neonatorum, subcutaneous fat necrosis, neurofibromatosis, benign tumors, or malignant tumors such as rhabdomyosarcoma, infantile fibrosarcoma, or neuroblastoma. We report a case of congenital subcutaneous fat necrosis in a 7-day-old baby presenting with multiple erythematous mass on back. PMID- 30288393 TI - Intensive Combination Immunotherapy and Neuroinflammation Resolution in a Child With Anti-PCA-1 (Yo) Paraneoplastic Syndrome and 2 Malignancies. AB - Paraneoplastic cerebellar degeneration is rare and noteworthy in children. In this 7-year-old, it was documented to have occurred within a year of ataxia presentation. The instigating cancer was stage III adrenal adenocarcinoma, remitted after surgical resection at age 2. When her severe ataxia progressed, neuroinflammation was characterized by high cerebrospinal fluid Purkinje cell cytoplasmic antibody type 1 titers, oligoclonal bands, and neurofilament light chain. The immunotherapy strategy was to replace IV methylprednisolone, which lowered Purkinje cell cytoplasmic antibody type 1 titers without clinical improvement, with induction of adrenocorticotropic hormone/intravenous immunoglobulin/rituximab (ACTH/IVIG/rituximab) combination immunotherapy, ACTH/dexamethasone transition, and intravenous immunoglobulin maintenance. She became self-ambulatory and cerebrospinal fluid inflammatory markers regressed. Down syndrome predisposed her to a second cancer, pre-B acute lymphoblastic leukemia, 4 years later. Despite reversible cytosine arabinoside-provoked cerebellar toxicity, the ataxia is stable on monthly intravenous immunoglobulin without relapse, now 5 years after initial diagnosis. This report illustrates the use of cerebrospinal fluid biomarkers to detect, target, and monitor neuroinflammation, and successful combinations of immunotherapy to better the quality of life. PMID- 30288395 TI - Effective Formats for Communicating Risks from Cigarette Smoke Chemicals. AB - Objective: The US government requires the public display of information about toxic chemicals in cigarettes and smoke by brand in a way that is understandable and not misleading. We sought to identify risk communication formats that meet these goals. Methods: We conducted 3 online experiments with US adult convenience samples (total N = 1866). Participants viewed a webpage displaying information about chemicals in the smoke of a cigarette brand. Experiment 1 varied the chemicals listed and format for their health effects. Experiments 2 and 3 varied the format of chemical quantities and presence/absence of a visual risk indicator. Outcomes were understandable (increasing knowledge) and not misleading (not reinforcing misperceptions). Results: Information about chemicals and health effects increased knowledge of these topics by ~30% (p < .001) compared to no information. Quantity format and use of a risk indicator generally did not affect knowledge. The proportion of participants misled ranged from 0% to 92%, depending on measure. Findings indicated 52% would use a website to search for safer cigarettes. Risk communication formats did little to reduce being misled. Conclusions: Some risk communication formats successfully increased knowledge of chemicals and health effects. However, the formats did little to reduce the proportion of people misled. PMID- 30288396 TI - Localized SDF-1alpha Delivery Increases Pro-Healing Bone Marrow-Derived Cells in the Supraspinatus Muscle Following Severe Rotator Cuff Injury. AB - To examine how the chemotactic agent stromal cell-derived factor-1alpha (SDF 1alpha) modulates the unique cellular milieu within rotator cuff muscle following tendon injury, we developed an injectable, heparin-based microparticle platform to locally present SDF-1alpha within the supraspinatus muscle following severe rotator cuff injury. SDF-1alpha loaded, degradable, N-desulfated heparin-based microparticles were fabricated, injected into a rat model of severe rotator cuff injury, and were retained for up to 7 days at the site. The resultant inflammatory cell and mesenchymal stem cell populations were analyzed compared to uninjured contralateral controls and, after 7 days, the fold-change in anti inflammatory, M2-like macrophages (CD11b+CD68+CD163+, 4.3X fold-change) and mesenchymal stem cells (CD29+CD44+CD90+, 3.0X, respectively) was significantly greater in muscles treated with SDF-1alpha loaded microparticles than unloaded microparticles or injury alone. Our results indicate that SDF-1alpha loaded microparticles may be a novel approach to shift the cellular composition within the supraspinatus muscle and create a more pro-regenerative milieu, which may provide a platform to improve muscle repair following rotator cuff injury in the future. PMID- 30288397 TI - The Great Recession and Immune Function. AB - The Great Recession precipitated unprecedented home foreclosures increases, but documentation of related neighborhood changes and population health is scant. Using the Detroit Neighborhood Health Study (N = 277), we examined associations between neighborhood-level recession indicators and thymic function, a life course immunological health indicator. In covariate-adjusted multilevel models, each 10 percentage point increase in abandoned home prevalence and 1 percentage point increase in 2009 home foreclosures was associated with 1.7-year and 3.3 year increases in thymic aging, respectively. Associations attenuated after adjustment for neighborhood-level social cohesion, suggesting community ties may buffer recession-related immune aging. Effects of neighborhood stressors were strongest in middle-income households, supporting theory of excess vulnerability in this group. Future research should assess whether ongoing foreclosure and blight reduction efforts improve health for residents of recession impacted neighborhoods. PMID- 30288398 TI - Synthetic Cathinones: A Brief Overview of Overviews with Applications to the Forensic Sciences. AB - Catha edulis, the fresh leaves of which (i.e., khat) are used for their central stimulant actions, has been known for many hundreds of years. S(-)Cathinone was identified as a centrally-active khat constituents >30 years ago. Although khat use was a problem long localized to certain Middle Eastern and certain Eastern African nations, 'synthetic cathinones' (synthetic analogs of cathinone) represent a "new" class of abused substances with growing worldwide appeal. To date, about 150 synthetic cathinones have been identified on the clandestine market, and only a dozen or so have been controlled (U.S. Schedule I). Because these agents do not represent a pharmacologically (i.e., behavioral) or mechanistically homogeneous class of agents, synthetic cathinones are being investigated one agent at a time to understand their actions, mechanisms of action, metabolism, toxicity, and abuse potential - the latter to identify possible modes of overdose treatment and for Scheduling purposes. The available agents might represent only the 'tip of the iceberg'; the potential for many more new synthetic cathinones is very real. Investigation of these agents on an agent by-agent basis is a daunting task. Attempts are being made to understand these agents as a class, by examination of their structure-activity relationships. Here, we provide an overview of review articles that attempts to shed light on these agents as a class, rather than on an agent-by-agent basis. This article is meant to be a reference resource that might expedite the work of those in this field by directing them to where they can find useful information. PMID- 30288399 TI - Is Shared Decision Making for End-of-Life Decisions Associated With Better Outcomes as Compared to Other Forms of Decision Making? A Systematic Literature Review. AB - Background: Whether shared decision making (SDM) has been evaluated for end-of life (EOL) decisions as compared to other forms of decision making has not been studied. Purpose: To summarize the evidence on SDM being associated with better outcomes for EOL decision making, as compared to other forms of decision making. Data Sources: PubMed, Web of Science, Cochrane Central Register of Controlled Trials, EMBASE, PsycINFO, and CINAHL databases were searched through April 2014. Study Selection: Studies were selected that evaluated SDM, compared to any other decision making style, for an EOL decision. Data Extraction: Components of SDM tested, comparators to SDM, EOL decision being assessed, and outcomes measured. Data Synthesis: Seven studies met the inclusion criteria (three experimental and four observational studies). Results were analyzed using narrative synthesis. All three experimental studies compared SDM interventions to usual care. The four observational studies compared SDM to doctor-controlled decision making, or reported the correlation between level of SDM and outcomes. Components of SDM specified in each study differed widely, but the component most frequently included was presenting information on the risks/benefits of treatment choices (five of seven studies). The outcome most frequently measured was communication, although with different measurement tools. Other outcomes included decisional conflict, trust, satisfaction, and "quality of dying." Limitations: We could not analyze the strength of evidence for a given outcome due to heterogeneity in the outcomes reported and measurement tools. Conclusions: There is insufficient evidence supporting SDM being associated with improved outcomes for EOL decisions as opposed to other forms of decision making. Future studies should describe which components of SDM are being tested, outline the comparator decision making style, and use validated tools to measure outcomes. PMID- 30288400 TI - Value of Information Analysis Informing Adoption and Research Decisions in a Portfolio of Health Care Interventions. AB - Background: Value of information (VOI) analysis quantifies the value of additional research in reducing decision uncertainty. It addresses adoption and research decisions simultaneously by comparing the expected benefits and costs of research studies. Nevertheless, the application of this approach in practice remains limited. Objectives: To apply VOI analysis in health care interventions to guide adoption decisions, optimize trial design, and prioritize research. Methods: The analysis was from the perspective of Queensland Health, Australia. It included four interventions: clinically indicated catheter replacement, tissue adhesive for securing catheters, negative pressure wound therapy (NPWT) in caesarean sections, and nutritional support for preventing pressure ulcers. For each intervention, cost-effectiveness analysis was performed, decision uncertainty characterized, and VOI calculated using Monte Carlo simulations. The benefits and costs of additional research were considered together with the costs and consequences of acting now versus waiting for more information. All values are reported in 2014 Australian dollars (AU$). Results: All interventions were cost-effective, but with various levels of decision uncertainty. The current evidence is sufficient to support the adoption of clinically indicated catheter replacement. For the tissue adhesive, an additional study before adoption is worthwhile with a four-arm trial of 220 patients per arm. Additional research on NPWT before adoption is worthwhile with a two-arm trial of 200 patients per arm. Nutritional support should be adopted with a two-arm trial of 1200 patients per arm. Based on the expected net monetary benefits, the studies were ranked as follows: 1) NPWT (AU$1.2 million), 2) tissue adhesive (AU$0.3 milliion), and 3) nutritional support (AU$0.1 million). Conclusions: VOI analysis is a useful and practical approach to inform adoption and research decisions. Efforts should be focused on facilitating its integration into decision making frameworks. PMID- 30288401 TI - Blood Pressure Control in Hypertensive Patients in Federally Qualified Health Centers: Impact of Shared Decision Making in the Office-GAP Program. AB - : Background: Hypertension (HTN) in people with diabetes doubles the risk of cardiovascular disease. Prior patient activation studies largely show improved communication but little impact on behavior or health outcomes. We sought to 1) assess the impact of Office-Based Guidelines Applied to Practice (Office-GAP) Program on blood pressure (BP) control; 2) determine the rate and predictors of BP control in patients with HTN and/or diabetes mellitus (DM) in federally qualified health centers. Methods: Sample: Patients with coronary heart disease (CHD) and/or DM with history of HTN; analyzed patients with DM and HTN compared to HTN without DM. INTERVENTION: Office-GAP included physician training, patient activation, and an Office-GAP decision checklist. Two-site intervention/control design; data collection at baseline and after 3, 6, and 12 months. Logistic regression with propensity scoring assessed impact on BP control over time. Results: Of 243 patients, HTN was present in 75% at baseline; 32% had BP controlled. Consistent trend showed Office-GAP slightly improved the rate of BP control across time, while the control arm showed a nonsignificant decrease in the rate of BP control across time, compared to baseline. BP improved at 6 months at the intervention site compared to control site (odds ratio = 2.92; 95% confidence interval = 1.11-7.69). Conclusion: BP control was better at the intervention site compared to the control site at 6 months. Office-GAP shows promise to implement guidelines-based patient-centered care that improves BP. PMID- 30288402 TI - Developing and Evaluating a Clinic-Based Decision Aid Delivery System. AB - Background: Despite evidence of their benefits, decision aids (DAs) have not been widely adopted in clinical practice. Quality improvement methods could help embed DA delivery into primary care workflows and facilitate DA delivery and uptake, defined as reading or watching DA materials. Objectives: 1) Work with clinic staff and providers to develop and test multiple processes for DA delivery; 2) implement a systems approach to measuring delivery and uptake; 3) compare uptake and patient satisfaction across delivery models. Methods: We employed a microsystems approach to implement three DA delivery models into primary care processes and workflows: within existing disease management programs, by physician request, and by mail. We developed a database and tracking tools linked to our electronic health record and designed clinic-based processes to measure uptake and satisfaction. Results: A total of 1144 DAs were delivered. Depending on delivery method, 51% to 73% of patients returned to the clinic within 6 months. Nurses asked 67% to 75% of this group follow-up questions, and 65% to 79% recalled receiving the DA. Among them, uptake was 23% to 27%. Satisfaction among patients who recalled receiving the DA was high. Eighty-two to 93% of patients reported that they liked receiving this patient education information, and 82% to 91% reported that receiving patient education information like this is useful to them. Conclusion: Our results demonstrate the realities of clinical practice. One fourth to one third of patients did not return for a follow-up visit. Although nurses were able to assess uptake in the course of their usual duties, the results did not achieve the standards typically expected of clinical research. Despite these limitations, uptake, though modest, was similar across delivery methods, suggesting that there are multiple strategies for implementing DAs in clinical practice. PMID- 30288403 TI - Barriers to and Facilitators of Evidence-Based Decision Making at the Point of Care: Implications for Delivery Systems, Payers, and Policy Makers. AB - Introduction: Physicians vary widely in how they treat some health conditions, despite strong evidence favoring certain treatments over others. We examined physicians' perspectives on factors that support or hinder evidence-based decisions and the implications for delivery systems, payers, and policymakers. Methods: We used Choosing Wisely(r) recommendations to create four clinical vignettes for common types of decisions. We conducted semi-structured interviews with 36 specialists to identify factors that support or hinder evidence-based decisions. We examined these factors using a conceptual framework that includes six levels: patients, physicians, practice sites, organizations, networks and hospital affiliations, and the local market. In this model, population characteristics and payer and regulatory factors interact to influence decisions. Results: Patient openness to behavior modification and expectations, facilitated and hindered physicians in making evidence-based recommendations. Physicians' communication skills were the most commonly mentioned facilitator. Practice site, organization, and hospital system barriers included measures of emergency department throughput, the order in which test options are listed in electronic health records (EHR), lack of relevant decision support in EHRs, and payment incentives that maximize billing and encourage procedures rather than medical management or counseling patients on behavior change. Factors from different levels interacted to undermine evidence-based care. Most physicians received billing feedback, but quality metrics on evidence-based service use were nonexistent for the four decisions in this study. Conclusions and Implications: Additional research and quality improvement may help to modify delivery systems to overcome barriers at multiple levels. Enhancing provider communication skills, improving decision support in EHRs, modifying workflows, and refining the design and interpretation of some quality metrics would help, particularly if combined with concurrent payment reform to realign financial incentives across stakeholders.

AB - One of the major hurdles to promoting informed decision making in health is the continued use of poor risk presentation formats. This article offers a guide to develop a Fact Box, a simple decision tool to present data about the benefits and harms of treatments that has been demonstrated to improve understanding of health risks, an important part of risk literacy. The article offers guidance about how to determine the evidence basis for a health topic, select outcomes to report, extract and present numbers or outcomes, and design the layout. The guide also addresses potential challenges for summarizing evidence and provides alternatives for addressing issues related to missing, insufficient, imprecise, or conflicting evidence and for dealing with issues related to statistical and clinical significance. The guide concludes with details on how to document the development of the Fact Box for the purpose of transparency and reproducibility. Fact Boxes are an efficient tool to promote risk literacy and should be available in every physician's office. PMID- 30288406 TI - Lay Judgments of Mental Health Treatment Options: The Mind Versus Body Problem. AB - Background: Past research shows that people believe psychologically caused mental disorders are helped by different treatments than biologically caused mental disorders. However, it is unknown how people think about treatment when limited information is known to identify the disorder. Objective: Our objective was to explore how laypeople judged the helpfulness of treatments when a limited set of mental health symptoms is presented. Method: Across four experiments, Mechanical Turk and college undergraduate participants (N = 331) read descriptions displaying sets of three mental health symptoms and rated how helpful pharmaceuticals, counseling, or alternative medicine would be on a 0 (not at all helpful) to 100 (completely helpful) scale. We measured judgments for perceived mental and medical symptoms (Experiment 1) and how judgments were influenced by symptom severity (Experiment 2), duration (Experiment 3), and if alternative medicine and conventional treatments were used in conjunction (Experiment 4). Results: Perceived mental symptoms were rated as helped by counseling, while perceived medical symptoms were rated as helped by medication. Alternative medicine was never rated as extremely helpful. For example, in Experiment 1, counseling (mean [M] = 80.1) was rated more helpful than pharmaceuticals (M = 50.5; P < 0.001) or alternative medicine (M = 45.1; P < 0.001) for mental symptoms, and pharmaceuticals (M = 62.6) was rated more helpful than counseling (M = 36.1; P < 0.001) or alternative medicine (M = 47.5; P < 0.001) for medical symptoms. This pattern held regardless of severity, duration, or the adjunct use of alternative medicine. Limitations: We employed a general population sample and measured hypothetical treatment judgments. Conclusions: Mental health symptoms viewed as problems of the mind are thought to need different treatment than mental health symptoms seen as problems of the body. PMID- 30288407 TI - Do Economic Evaluations in Primary Care Prevention and the Management of Hypertension Conform to Good Practice Guidelines? A Systematic Review. AB - Background: Results of previous research have identified the need for further investigation into the compliance with good practice guidelines for current decision-analytic modeling (DAM). Objective: To identify the extent to which recent model-based economic evaluations of interventions focused on lowering the blood pressure (BP) of patients with hypertension conform to published guidelines for DAM in health care using a five-dimension framework developed to assess compliance to DAM guidelines. Methods: A systematic review of English language articles was undertaken to identify published model-based economic evaluations that examined interventions aimed at lowering BP. The review covered the period January 2000 to March 2015 and included the following electronic bibliographic databases: EMBASE and Medline via Ovid interface and the Centre for Reviews and Dissemination's (CRD) NHS-EED. Data were extracted based on different components of good practice across five dimensions utilizing a framework to assess compliance to DAM guidelines. Results: Thirteen articles were included in this review. The review found limited compliance to good practice DAM guidelines, which was most frequently justified by the lack of data. Conclusions: The assessment of structural uncertainty cannot yet be considered common practice in primary prevention and management of hypertension, and researchers seem to face difficulties with identifying sources of structural uncertainty and then handling them correctly. Additional guidelines are needed to aid researchers in identifying and managing sources of potential structural uncertainty. Adherence to guidelines is not always possible and it does pose challenges, in particular when there are limitations due to data availability that restrict, for example, a validation process. PMID- 30288408 TI - Impact of the "Linked Evidence Approach" Method on Policies to Publicly Fund Diagnostic, Staging, and Screening Medical Tests. AB - Background: The linked evidence approach (LEA) is used in health technology assessment (HTA) to evaluate the clinical utility of new medical tests in the absence of direct trial evidence. Objective: To determine whether use of LEA affects decisions to publicly fund medical tests. Methods: Australian HTAs that evaluated medical tests before and after LEA was mandated (in 2005) were screened for eligibility. Data were extracted and the impact of LEA and other possible clinical predictors (selected a priori) on funding decisions was modelled. Regression diagnostics were performed to estimate model fit, model specification, and to inform model selection. The unit of analysis was per clinical indication for each new test, so analyses were adjusted for clustering. Results: 83 HTAs (for 173 clinical indications) were eligible from the 259 screened. When health policy was compared before and after 2005, there was an 11% reduction in overall positive funding decisions, including a 25% decrease in "interim" (coverage with evidence development) funding decisions. The odds of obtaining interim funding reduced by 98% (odds ratio = 0.02, 95% confidence interval = 0.0005, 0.17), but there was no change in the direction of funding decisions (odds ratio = 1.36, 95% confidence interval = 0.62, 3.01). Across both time periods, when LEA was used there was a very strong likelihood that the medical test would not receive interim funding (chi2 = 12.63, df = 1, P = 0.001). For positive funding decisions, the strongest predictors were whether or not the new test would replace an existing test and whether the available evidence was limited. Conclusions: The use of LEA did not predict the direction of funding decisions. Application of the method did predict that a "coverage with evidence development" decision was unlikely. This suggests that LEA may reduce decision-maker uncertainty. PMID- 30288409 TI - Data-Driven Markov Decision Process Approximations for Personalized Hypertension Treatment Planning. AB - Background: Markov decision process (MDP) models are powerful tools. They enable the derivation of optimal treatment policies but may incur long computational times and generate decision rules that are challenging to interpret by physicians. Methods: In an effort to improve usability and interpretability, we examined whether Poisson regression can approximate optimal hypertension treatment policies derived by an MDP for maximizing a patient's expected discounted quality-adjusted life years. Results: We found that our Poisson approximation to the optimal treatment policy matched the optimal policy in 99% of cases. This high accuracy translates to nearly identical health outcomes for patients. Furthermore, the Poisson approximation results in 104 additional quality-adjusted life years per 1000 patients compared to the Seventh Joint National Committee's treatment guidelines for hypertension. The comparative health performance of the Poisson approximation was robust to the cardiovascular disease risk calculator used and calculator calibration error. Limitations: Our results are based on Markov chain modeling. Conclusions: Poisson model approximation for blood pressure treatment planning has high fidelity to optimal MDP treatment policies, which can improve usability and enhance transparency of more personalized treatment policies. PMID- 30288410 TI - Computer-assisted Medical Decision-making System for Diagnosis of Urticaria. AB - Background: Urticaria is a common allergic disease that affects all age groups. Allergic disorders are diagnosed at allergy testing centers using skin tests. Though skin tests are the gold standard tests for allergy diagnosis, specialists are required to interpret the observations and test results. Hence, a computer assisted medical decision-making (CMD) system can be used as an aid for decision support, by junior clinicians, in order to diagnose the presence of urticaria. Methods: The data from intradermal skin test results of 778 patients, who exhibited allergic symptoms, are considered for this study. Based on food habits and the history of a patient, 40 relevant allergens are tested. Allergen extracts are used for skin test. Ten independent runs of 10-fold cross-validation are used to train the system. The performance of the CMD system is evaluated using a set of test samples. The test samples were also presented to the junior clinicians at the allergy testing center to diagnose the presence or absence of urticaria. Results: From a set of 91 features, a subset of 41 relevant features is chosen based on the relevance score of the feature selection algorithm. The Bayes classification approach achieves a classification accuracy of 96.92% over the test samples. The junior clinicians were able to classify the test samples with an average accuracy of 75.68%. Conclusion: A probabilistic classification approach is used for identifying the presence or absence of urticaria based on intradermal skin test results. In the absence of an allergy specialist, the CDM system assists junior clinicians in clinical decision making. PMID- 30288411 TI - How Do Psychiatrists Apply the Minimum Clinically Important Difference to Assess Patient Responses to Treatment? AB - Symptom report scales are used in clinical practice to monitor patient outcomes. Using them permits the definition of a minimum clinically important difference (MCID) beyond which a patient may be judged as having responded to treatment. Despite recommendations that clinicians routinely use MCIDs in clinical practice, statisticians disagree about how MCIDs should be used to evaluate individual patient outcomes and responses to treatment. To address this issue, we asked how clinicians actually use MCIDs to evaluate patient outcomes in response to treatment. Sixty-eight psychiatrists made judgments about whether hypothetical patients had responded to treatment based on their pre- and posttreatment change scores on the widely used Positive and Negative Syndrome Scale. Psychiatrists were provided with the scale's MCID on which to base their judgments. Our secondary objective was to assess whether knowledge of the patient's genotype influenced psychiatrists' responder judgments. Thus, psychiatrists were also informed of whether patients possessed a genotype indicating hyperresponsiveness to treatment. While many psychiatrists appropriately used the MCID, others accepted a far lower posttreatment change as indicative of a response to treatment. When psychiatrists accepted a lower posttreatment change than the MCID, they were less confident in such judgments compared to when a patient's posttreatment change exceeded the scale's MCID. Psychiatrists were also less likely to identify patients as responders to treatment if they possessed a hyperresponsiveness genotype. Clinicians should recognize that when judging patient responses to treatment, they often tolerate lower response thresholds than warranted. At least some conflate their judgments with information, such as the patient's genotype, that is irrelevant to a post hoc response-to-treatment assessment. Consequently, clinicians may be at risk of persisting with treatments that have failed to demonstrate patient benefits. PMID- 30288412 TI - Patient and Provider Perspectives on Mammographic Breast Density Notification Legislation. AB - Background: Patient advocacy has fostered the implementation of mammographic breast density (MBD) notification legislation in many states. Little is known about the perspectives of women, primary care physicians (PCPs), and breast radiologists in response to this legislation. The objective of this research was to elicit qualitative information from these multiple stakeholders to understand varied perspectives on the subject of MBD notification and inform best practices around implementation. Methods: Content analysis of narrative data from focus groups with women (2 groups, total of 16 participants) and in-depth interviews with PCPs (n = 7) and breast radiologists (n = 7). Results: Three major themes emerged from the data: 1) knowledge and general attitudes about legislation, 2) concerns about consequences, and 3) actions patients and clinicians should consider based on MBD information. For each of these themes, the views of women, PCPs, and radiologists often demonstrated different perspectives. Conclusion: This work supports the need for clear and concise tools for patients and providers to understand MBD in the context of a woman's overall breast cancer risk with guidance on next steps. PMID- 30288413 TI - What Factors Affect Physicians' Decisions to Prescribe Opioids in Emergency Departments? AB - Objective: With 42% of all emergency department visits in the United States related to pain, physicians who work in this setting are tasked with providing adequate pain management to patients with varying primary complaints and medical histories. Complicating this, the United States is in the midst of an opioid overdose epidemic. State governments and national organizations have developed guidelines and legislation to curtail opioid prescriptions in acute care settings, while also incentivizing providers for patient satisfaction and completeness of pain control. In order to inform future policies that focus on provider pain medication prescribing, we sought to characterize the factors physicians weigh when considering treating pain with opioids in the emergency department. Methods: We conducted and transcribed open-ended, semistructured qualitative interviews with 52 physicians at a national emergency medicine conference. Results: Participants reported a wide range of factors contributing to their opioid prescribing patterns related to three domains: 1) provider assessment of pain characteristics, 2) patient-based considerations, and 3) practice environment. Pain characteristics include the characteristics of various acute and chronic pain syndromes, including physicians' empathy due to their own experiences with pain. Patient characteristics include "trustworthiness," race and ethnicity, and the concern for risk of misuse. Factors related to the practice environment include hospital policy, legislation/regulation, and guidelines. Conclusion: The decision to prescribe opioids to patients in the emergency department is complex and nuanced. Physicians are interested in guidance and are concerned about the competing pressures placed on their opioid prescribing due to incentives related to patient satisfaction scores on one hand and inflexible policies that do not allow for individualized, patient-centered decisions on the other. PMID- 30288414 TI - Optimizing Implementation of Hepatitis C Birth-Cohort Screening and Treatment Strategies: Model-Based Projections. AB - Background: Chronic hepatitis C (HCV) is a significant public health problem affecting more than three million Americans. The US health care systems are ramping up costly HCV screening and treatment efforts with limited budget. We determine the optimal implementation of HCV birth-cohort screening and treatment strategies under budget constraints and health care payer's perspective. Methods: Markov model and scenario-based simulation optimization. The target population is birth cohort born between 1945 and 1975. The interventions are allocating annual budget to screen a proportion of the target population and treat a proportion of the identified chronic HCV-positive patients over 10 years. Outcomes measure is to maximize lifetime discounted quality-adjusted life-years. Results: Allocate a percentage of the annual budget to screening, then treat patients with the remaining budget and prioritize the sickest patients. When the budget is $1 billion/year, the best strategy is to allocate the entire budget to treatment. When the budget is $5 billion/year, it is optimal to allocate 60% of the budget to screening in the first 2 years and 0% thereafter for age cohort 40 to 49; and allocate 20% of the budget to screening starting in year 3 for age cohorts 50 to 59 and 60 to 69. Health benefits are sensitive to budget in the first 2 years. Results are not sensitive to distribution of fibrosis stages by awareness of HCV. Conclusion: When budget is limited, all efforts should be focused on early treatment. With higher budget, better population health outcomes are achieved by reserving some budget for HCV screening while implementing a priority-based treatment strategy. This work has broad applicability to diverse health care systems and helps determine how much effort should be devoted to screening versus treatment under resource limitations. PMID- 30288415 TI - Designing the Free Drugs List in Nepal: A Balancing Act Between Technical Strengths and Policy Processes. AB - As more countries provide free health care, pharmaceutical reimbursement lists are becoming a concern, especially in low- and middle-income countries. In 2007, Nepal decreed that health is a human right and began basic health coverage for a target group of the poor, destitute, elderly, and disabled. The Ministry of Health and Population (MoHP) also provided 40 drugs without cost to all citizens through the Free Drugs List (FDL) program. The FDL was later expanded from 40 to 70 drugs; however, the process of review and update remains unclear. To propose a mechanism for future development of the FDL, we conducted a document review and in-depth consultations with representatives from the MoHP and the World Health Organization Country Office during a workshop in Kathmandu. The FDL suffers from lack of an appropriate process, gaps between the listed drugs and Nepal's burden of disease, and no consideration of the unit costs or cost-effectiveness of drugs included in the list. We propose a new drug selection process that is a variant of the health technology assessment process. This process can be applied not only in Nepal but also in other resource-limited countries that wish to ensure their citizens' access to essential medicines through a pharmaceutical reimbursement list. PMID- 30288416 TI - The External Validity of Mapping MSIS-29 on EQ-5D Among Individuals With Multiple Sclerosis in Sweden. AB - Background: Mapping can be performed to predict utility values from condition specific measures when preference-based measures are absent. A previously developed algorithm that predicts EQ-5D-3L index values from the Multiple Sclerosis Impact Scale (MSIS-29) has not yet been externally validated. Aim: To examine the external validity of a previously developed mapping algorithm by testing the accuracy of predicting EQ-5D-3L index values from MSIS-29 among multiple sclerosis (MS) patients in Sweden. Methods: Cross-sectional individual level data were collected from population-based Swedish registers between 2011 and 2014. Health-related quality of life was assessed through MSIS-29 and EQ-5D 3L at one point in time among 767 individuals with known disability level of MS. A previously developed mapping algorithm was applied to predict EQ-5D index values from MSIS-29 items, and the predictive accuracy was assessed through mean absolute error and root mean square error. Results: When applying the algorithm, the predicted mean EQ-5D-3L index value was 0.77 compared to the observed mean index value of 0.75. Prediction error was higher for individuals reporting EQ-5D values <0.5 compared to individuals reporting EQ-5D values >=0.5. Mean absolute error (0.12) and root mean square error (0.18) were smaller or equal to the prediction errors found in the original mapping study. Conclusion: The mapping algorithm had similar predictive accuracy in the two independent samples although results showed that the highest predictive performance was found in groups with better health. Varied predictive accuracy in subgroups is consistent with previous studies and strategies to deal with this are warranted. PMID- 30288417 TI - Costs and Benefits of Including Inactivated in Addition to Oral Poliovirus Vaccine in Outbreak Response After Cessation of Oral Poliovirus Vaccine Use. AB - Background: After stopping serotype 2-containing oral poliovirus vaccine use, serotype 2 poliovirus outbreaks may still occur and require outbreak response supplemental immunization activities (oSIAs). Current oSIA plans include the use of both serotype 2 monovalent oral poliovirus vaccine (mOPV2) and inactivated poliovirus vaccine (IPV). Methods: We used an existing model to compare the effectiveness of mOPV2 oSIAs with or without IPV in response to a hypothetical postcessation serotype 2 outbreak in northwest Nigeria. We considered strategies that co-administer IPV with mOPV2, use IPV only for older age groups, or use only IPV during at least one oSIA. We considered the cost and supply implications and estimated from a societal perspective the incremental cost-effectiveness and incremental net benefits of adding IPV to oSIAs in the context of this hypothetical outbreak in 2017. Results: Adding IPV to the first or second oSIA resulted in a 4% to 6% reduction in expected polio cases compared to exclusive mOPV2 oSIAs. We found the greatest benefit of IPV use if added preemptively as a ring around the initial oSIA target population, and negligible benefit if added to later oSIAs or older age groups. We saw an increase in expected polio cases if IPV replaced mOPV2 during an oSIA. None of the oSIA strategies that included IPV for this outbreak represented a cost-effective or net beneficial intervention compared to reliance on mOPV2 only. Conclusions: While adding IPV to oSIAs results in marginal improvements in performance, the poor cost-effectiveness and current limited IPV supply make it economically unattractive for high-risk settings in which IPV does not significantly affect transmission. PMID- 30288418 TI - Illustration of the Impact of Unmeasured Confounding Within an Economic Evaluation Based on Nonrandomized Data. AB - Background: Propensity score (PS) methods are frequently used within economic evaluations based on nonrandomized data to adjust for measured confounders, but many researchers omit the fact that they cannot adjust for unmeasured confounders. Objective: To illustrate how confounding due to unmeasured confounders can bias an economic evaluation despite PS matching. Methods: We used data from a previously published nonrandomized study to select a prematched population consisting of 121 patients (46.5%) who received endovascular aneurysm repair (EVAR) and 139 patients (53.5%) who received open surgical repair (OSR), in which sufficient data regarding eight measured confounders were available. One to-one PS matching was used within this population to select two PS-matched subpopulations. The Matched PS-Smoking Excluded Subpopulation was selected by matching patients using a PS model that omitted patients' smoking status (one of the measured confounders), whereas the Matched PS-Smoking Included Subpopulation was selected by matching patients using a PS model that included all eight measured confounders. Incremental cost-effectiveness ratios (ICERs) were assessed within both subpopulations. Results: Both subpopulations were composed of two different sets of 164 patients. Balance within the Matched PS-Smoking Excluded Subpopulation was achieved on all confounders except for patients' smoking status, whereas balance within the Matched PS-Smoking Included Subpopulation was achieved on all confounders. Results indicated that the ICER of EVAR over OSR differed between both subpopulations; the ICER was estimated at $157,909 per life year gained (LYG) within the Matched PS-Smoking Excluded Subpopulation, while it was estimated at $235,074 per LYG within the Matched PS-Smoking Included Subpopulation. Discussion: Although effective in controlling for measured confounding, PS matching may not adjust for unmeasured confounders that may bias the results of an economic evaluation based on nonrandomized data. PMID- 30288420 TI - Parental Preferences for the Organization of Preschool Vaccination Programs Including Financial Incentives: A Discrete Choice Experiment. AB - Objective: To establish preferences of parents and guardians of preschool children for the organization of preschool vaccination services, including financial incentives. Design: An online discrete choice experiment. Participants: Parents and guardians of preschool children (up to age 5 years) who were (n = 259) and were not (n = 262) classified as at high risk of incompletely vaccinating their children. High risk of incomplete vaccination was defined as any of the following: aged less than 20 years, single parents, living in one of the 20% most deprived areas in England, had a preschool child with a disability, or had more than three children. Main Outcome Measures: Participant preferences expressed as positive (utility) or negative (disutility) on eight attributes and levels describing the organization of preschool vaccination programs. Results: There was no difference in preference for parental financial incentives compared to no incentive in parents "not at high risk" of incomplete vaccination. Parents who were "at high risk" expressed utility for cash incentives. Parents "at high risk" of incomplete vaccination expressed utility for information on the risks and benefits of vaccinations to be provided as numbers rather than charts or pictures. Both groups preferred universally available, rather than targeted, incentives. Utility was identified for shorter waiting times, and there were variable preferences for who delivered vaccinations. Conclusions: Cash incentives for preschool vaccinations in England would be welcomed by parents who are "at high risk" of incompletely vaccinating their children. Further work is required on the optimal mode and form of presenting probabilistic information on vaccination to parents/guardians, including preferences on mandatory vaccination schemes. PMID- 30288419 TI - Encouraging Medicare Advantage Enrollees to Switch to Higher Quality Plans: Assessing the Effectiveness of a "Nudge" Letter. AB - There are considerable quality differences across private Medicare Advantage insurance plans, so it is important that beneficiaries make informed choices. During open enrollment for the 2013 coverage year, the Centers for Medicare & Medicaid Services sent letters to beneficiaries enrolled in low-quality Medicare Advantage plans (i.e., plans rated less than 3 stars for at least 3 consecutive years by Medicare) explaining the stars and encouraging them to reexamine their choices. To understand the effectiveness of these low-cost, behavioral "nudge" letters, we used a beneficiary-level national retrospective cohort and performed multivariate regression analysis of plan selection during the 2013 open enrollment period among those enrolled in plans rated less than 3 stars. Our analysis controls for beneficiary demographic characteristics, health and health care spending risks, the availability of alternative higher rated plan options in their local market, and historical disenrollment rates from the plans. We compared the behaviors of those beneficiaries who received the nudge letters with those who enrolled in similar poorly rated plans but did not receive such letters. We found that beneficiaries who received the nudge letter were almost twice as likely (28.0% [95% confidence interval = 27.7%, 28.2%] vs. 15.3% [95% confidence interval = 15.1%, 15.5%]) to switch to a higher rated plan compared with those who did not receive the letter. White beneficiaries, healthier beneficiaries, and those residing in areas with more high-performing plan choices were more likely to switch plans in response to the nudge. Our findings highlight both the importance and efficacy of providing timely and actionable information to beneficiaries about quality in the insurance marketplace to facilitate informed and value-based coverage decisions. PMID- 30288421 TI - Efficient and Fair Heart Allocation Policies for Transplantation. AB - Background: The optimal allocation of limited donated hearts to patients on the waiting list is one of the top priorities in heart transplantation management. We developed a simulation model of the US waiting list for heart transplantation to investigate the potential impacts of allocation policies on several outcomes such as pre- and posttransplant mortality. Methods: We used data from the United Network for Organ Sharing (UNOS) and the Scientific Registry of Transplant Recipient (SRTR) to simulate the heart allocation system. The model is validated by comparing the outcomes of the simulation with historical data. We also adapted fairness schemes studied in welfare economics to provide a framework to assess the fairness of allocation policies for transplantation. We considered three allocation policies, each a modification to the current UNOS allocation policy, and analyzed their performance via simulation. The first policy broadens the geographical allocation zones, the second modifies the health status order for receiving hearts, and the third prioritizes patients according to their waiting time. Results: Our results showed that the allocation policy similar to the current UNOS practice except that it aggregates the three immediate geographical allocation zones, improves the health outcomes, and is "closer" to an optimal fair policy compared to all other policies considered in this study. Specifically, this policy could have saved 319 total deaths (out of 3738 deaths) during the 2006 to 2014 time horizon, in average. This policy slightly differs from the current UNOS allocation policy and allows for easy implementation. Conclusion: We developed a model to compare the outcomes of heart allocation policies. Combining the three immediate geographical zones in the current allocation algorithm could potentially reduce mortality rate and is closer to an optimal fair policy. PMID- 30288423 TI - Life Expectancy Predictions for Older Diabetic Patients as Estimated by Physicians and a Prognostic Model. AB - : Background: Multiple medical organizations recommend using life expectancy (LE) to individualize diabetes care goals. We compare the performance of patient LE predictions made by physicians to LE predictions from a simulation model (the Chicago model) in a cohort of older diabetic patients. DESIGN: Retrospective cohort study of a convenience sample (n = 447) of diabetes patients over 65 years and their physicians. Measurements: Physicians provided LE estimates for individual patients during a baseline survey (2000-2003). The prognostic model included a comprehensive geriatric type 2 diabetes simulation model (the Chicago model) and combinations of the physician estimate and the Chicago model ("And," "Or," and "Average" models). Observed survival was determined based on the National Death Index through 31 December 2010. The predictive accuracy of LE predictions was assessed using c-statistic for 5-year mortality; Harrell's c statistic, and Integrated Brier score for overall survival. Results: The patient cohort had a mean (SD) age of 73.4 (5.9) years. The majority were female (62.6%) and black (79.4%). At 5 years, 108 (24.2%) patients had died. The c-statistic for 5-year mortality was similar for physicians (0.69) and the Chicago model (0.68), while the average of estimates by physicians and Chicago model yielded the highest c-statistic of any method tested (0.73). The estimates of overall survival yielded a similar pattern of results. Limitations: Generalizability of patient cohort and lack of updated model parameters. Conclusions: Compared with individual methods, the average of LE estimates by physicians and the Chicago model had the best predictive performance. Prognostic models, such as the Chicago model, may complement and support physicians' intuitions as they consider treatment decisions and goals for older patients with chronic conditions like diabetes. PMID- 30288424 TI - Tailoring Educational and Behavioral Interventions to Level of Health Literacy: A Systematic Review. AB - Background: The relative value of universal compared to contingent approaches to communication and behavioral interventions for persons of low health literacy remains unknown. Objective: To examine the effectiveness of interventions that are tailored to individual health literacy level compared to nontailored interventions on health-related outcomes. Design: Systematic review. Data Sources: PubMed and Embase databases. Eligibility Criteria: Studies were eligible if they were in English, used an experimental or observational design, included an intervention that was tailored based on the individual's level of education, health literacy or health numeracy, and had a comparator group in which the intervention was not tailored to individual characteristics. Review Methods: Databases were searched from inception to January 2016, and the retrieved reference lists hand searched. Abstracts that met PICOS criteria underwent dual review for data extraction to assess study details and study quality. A qualitative synthesis was conducted. Results: Of 2,323 unique citations, 458 underwent full review, and 9 met criteria for the systematic review. Five studies were positive and rated as good quality, 3 were negative with 2 of those of good quality, and 1 had mixed results (fair quality). Positive studies were conducted in the clinical domains of hypertension, diabetes, and depression with interventions including educational materials, disease management sessions, literacy training, and physician notification of limited health literacy among patients. Negative studies were conducted in the clinical domains of heart disease, glaucoma, and nutrition with interventions including medication reconciliation and educational materials. Conclusions: Tailoring communication and behavioral interventions to the individual level of health literacy may be an effective strategy to improve knowledge and indicators of disease control in selected clinical settings. PMID- 30288422 TI - Adjuvant Versus Salvage Radiotherapy for Patients With Adverse Pathological Findings Following Radical Prostatectomy: A Decision Analysis. AB - Background: Patients undergoing surgery for prostate cancer who have adverse pathological findings experience high rates of recurrence. While there are data supporting adjuvant radiotherapy compared to a wait-and-watch strategy to reduce recurrence rates, there are no randomized controlled trials comparing adjuvant radiotherapy with the other standard of care, salvage radiotherapy (radiotherapy administered at the time of recurrence). Methods: We constructed a health state transition (Markov) model employing two-dimensional Monte Carlo simulation using a lifetime horizon to compare the quality-adjusted survival associated with postoperative strategies using adjuvant or salvage radiotherapy. Prior to analysis, we calibrated and validated our model using the results of previous randomized controlled trials. We considered clinically important oncological health states from immediately postoperative to prostate cancer-specific death, commonly described complications from prostate cancer treatment, and other causes of mortality. Transition probabilities and utilities for disease states were derived from a literature search of MEDLINE and expert consensus. Results: Salvage radiotherapy was associated with an increased quality-adjusted life expectancy (QALE) (58.3 months) as compared with adjuvant radiotherapy (53.7 months), a difference of 4.6 months (standard deviation 8.8). Salvage radiotherapy had higher QALE in 53% of hypothetical cohorts. There was a minimal difference in overall life expectancy (-0.1 months). Examining recurrence rates, our model showed validity when compared with available randomized controlled data. Conclusions: A salvage radiotherapy strategy appears to provide improved QALE for patients with adverse pathological findings following radical prostatectomy, compared with adjuvant radiotherapy. As these findings reflect, population averages, specific patient and tumor factors, and patient preferences remain central for individualized management. PMID- 30288425 TI - Development, Validation, and Implementation of a Medical Judgment Metric. AB - Background: Medical decision making is a critical, yet understudied, aspect of medical education. Aims: To develop the Medical Judgment Metric (MJM), a numerical rubric to quantify good decisions in practice in simulated environments; and to obtain initial preliminary evidence of reliability and validity of the tool. Methods: The individual MJM items, domains, and sections of the MJM were built based on existing standardized frameworks. Content validity was determined by a convenient sample of eight experts. The MJM instrument was pilot tested in four medical simulations with a team of three medical raters assessing 40 participants with four levels of medical experience and skill. Results: Raters were highly consistent in their MJM scores in each scenario (intraclass correlation coefficient 0.965 to 0.987) as well as their evaluation of the expected patient outcome (Fleiss's Kappa 0.791 to 0.906). For each simulation scenario, average rater cut-scores significantly predicted expected loss of life or stabilization (Cohen's Kappa 0.851 to 0.880). Discussion: The MJM demonstrated preliminary evidence of reliability and validity. PMID- 30288426 TI - Shared Decision-Making Tool for Self-Management of Home Therapies for Patients With Cystic Fibrosis. AB - Objective: Patients with cystic fibrosis (CF) undertake time-consuming programs of home therapies. Our objective was to develop a tool to help CF patients prioritize personal goals for some of these treatments. We describe the development and results of initial evaluation of this shared decision-making tool. Methods: Multicriteria decision-making method to develop a shared decision making tool that integrates patient's values and perceptions of treatment impact on functionality/sense of well-being. Treatment efficacy data obtained through comprehensive review of English language literature and Cochrane reviews. Field study of 21 patients was performed to assess acceptability of the approach, understandability of the tool, and to determine whether there was sufficient patient-to-patient variability in treatment goals and patient preferences to make use of a personalized tool worthwhile. Results: Patients found the tool easy to understand and felt engaged as active participants in their care. The tool was responsive to variations in patient preferences. Priority scores were calculated (0-1.0 +/- SD). Patients' most important treatment goals for improving lung health included improving breathing function (0.27 +/- 0.11), improving functionality/sense of well-being (0.24 +/- 0.13), preventing lung infection (0.21 +/- 0.08), minimizing time to complete treatments (0.16 +/- 0.12), and minimizing cost (0.11 +/- 0.09). Conclusions: A shared decision-making tool that integrates patients' values and best evidence is feasible and could result in improved patient engagement in their own care.

AB - : Objective: Explore the perspectives, decision-making process, and final mode of delivery among pregnant women with a previous C-section (Cesarean section) in a general public sector hospital in Lima, Peru. Methods: A qualitative prospective study using semistructured interviews at two time points in the outpatient obstetrics and gynecology clinic of a public sector, university-affiliated reference hospital in Lima, Peru. Seventeen adult pregnant women with a prior C section who were deemed by their attending obstetrician to be candidates for a trial of labor were interviewed. The first interview was between 37 and 38 weeks of pregnancy, and the second interview was 24 to 48 hours after delivery. MAIN OUTCOME MEASURES: Predelivery decision-making process and final mode of delivery. Results: Among the 17 participants, about half (9) of the participants stated that the physician explained that they had two approaches for delivery, a trial of labor after C-section (TOLAC) or elective repeated C-section (ERCD). Two women stated that their respective providers explained only one option, either an ERCD or TOLAC. However, 6 women did not receive any information from their providers about their delivery options. Of the 10 participants that decided TOLAC, 8 ended up having a C-section, and of the 7 patients that had planned an ERCD, 1 ended up having a vaginal delivery. Conclusion: Many participants affirmed that they made the decision about their approach of delivery. However, most of the participants that decided a TOLAC ended up having a C-section because of complications during the final weeks of pregnancy or during labor.

AB - Objectives: The Medical Outcomes Study HIV Health Survey (MOS-HIV) is frequently used in HIV clinical trials; however, scores generated from the MOS-HIV are not suited for cost-effectiveness analyses as they do not assign utility values to health states. Our objective was to estimate and externally validate several mapping algorithms to predict Health Utilities Index Mark 3 (HUI3) and EQ-5D-3L utility values from the MOS-HIV. Methods: We developed and validated mapping algorithms using data from two HIV clinical trials. Data from the first trial (n = 367) formed the estimation data set for the HUI3 (4,610 observations) and EQ-5D 3L (4,662 observations) mapping algorithms; data from the second trial (n = 168) formed the HUI3 (1,135 observations) and EQ-5D-3L (1,152 observations) external validation data set. We compared ordinary least squares (OLS) models of increasing complexity with the more flexible two-part, beta regression, and finite mixture models. We assessed model performance using mean absolute error (MAE) and mean squared error (MSE). Results: The OLS model that used MOS-HIV dimension scores along with squared terms gave the best HUI3 predictions (mean observed 0.84; mean predicted 0.80; MAE 0.0961); the finite mixture model gave the best EQ-5D-3L predictions (mean observed 0.90; mean predicted 0.88; MAE 0.0567). All models produced higher prediction errors at the lower end of the HUI3 and EQ-5D-3L score ranges (<0.40). Conclusions: The proposed mapping algorithms can be used to predict HUI3 and EQ-5D-3L utility values from the MOS HIV, although greater error may pose a problem in samples where a substantial proportion of patients are in poor health. These algorithms may be useful for estimating utility values from the MOS-HIV for cost-effectiveness studies when HUI3 or EQ-5D-3L data are not available. PMID- 30288429 TI - Black-White Cardiovascular Disease Disparities After Target-Based Versus Personalized Benefit-Based Lipid and Blood Pressure Treatment. AB - Background: Cardiovascular disease (CVD) remains the leading cause of black-white morbidity and mortality disparities in the United States. Objectives: We sought to compare black-white CVD morbidity and mortality if lipid and blood pressure treatments were prescribed to achieve targeted lipid and blood pressure levels (treat-to-target [TTT]) or personalized CVD risk and treatment benefit estimates (benefit-based tailored treatment [BTT]). Methods: We utilized a microsimulation model of statin and blood pressure treatment based on a TTT approach (Joint National Commission 7; Adult Treatment Panel III) or a BTT approach (treating those with 10-year CVD risk >=10%, a modification and extension of recent American College of Cardiology/American Heart Association guidelines). We input data from the National Health and Nutrition Examination Survey, isolating adults 40 to 75 years of age without prior CVD events. Results: We observed that TTT would prevent fewer CVD events (17.0 events prevented per 1,000 whites, 22.2 per 1,000 blacks) than the BTT approach (25.9 events prevented per 1,000 whites, 45.4 per 1,000 blacks). TTT could lower the national black-white CVD event rate disparity from 23.1 excess events per 1,000 blacks to 17.9 excess events (-23%), while BTT could lower the disparity to 3.6 excess events (-84% overall). The inferiority of TTT to BTT remained consistent in sensitivity analyses testing alternative treatment targets and either over- or underestimation of risk by commonly used equations. Conclusions: A BTT approach to lipid and blood pressure treatment would be expected to prevent more CVD events in the overall population and more effectively reduce national black-white CVD disparities than a traditional TTT approach. PMID- 30288430 TI - Economic Evaluation Alongside a Randomized Controlled Crossover Trial of Modified Group Cognitive-Behavioral Therapy for Anxiety Compared to Treatment-as-Usual in Adults With Asperger Syndrome. AB - Background: There is a growing interest in using group cognitive-behavioral therapy (CBT) with people who have Asperger syndrome (AS) and comorbid mental health problems. This study aims to assess the cost-effectiveness of modified group CBT for adults with AS experiencing co-occurring anxiety compared to treatment-as-usual. Methods: Economic evaluation alongside a pilot, multicenter, single-blind, randomized controlled crossover trial. Costs from the UK public sector (National Health Service and Social Services) and societal perspectives, quality-adjusted life years (QALYs), incremental net (monetary) benefit (INB), expected value of perfect information, expected value of sample information, expected net gain of sampling, and efficient sample size of a future trial are reported. Results: Over 48 weeks, from the societal perspective, CBT results in additional costs of L6,647, with only a 0.015 incremental gain in QALYs, leading to a negative INB estimate of L6,206 and a 23% probability of cost-effectiveness at a threshold of L30,000/QALY. Results from sensitivity analyses support the unlikely cost-effectiveness of CBT but indicate the potential for cost effectiveness over longer time horizons. Eliminating decision uncertainty is valued at L277 million, and the efficient sample size for a future trial is estimated at 1,200 participants per arm. Limitations: Relatively small sample size and prevalence of missing data present challenges to the interpretation of the results. Conclusions: Current evidence from this small pilot study suggests that, on average, modified group CBT is not cost-effective. However, there is much decision uncertainty so such a conclusion could be wrong. A large, full scale trial to reduce uncertainty would be an efficient investment for the UK health economy. PMID- 30288431 TI - Comparative Effectiveness of Up To Three Lines of Chemotherapy Treatment Plans for Metastatic Colorectal Cancer. AB - Modern chemotherapy agents transformed standard care for metastatic colorectal cancer (mCRC) but raised concerns about the financial burden of the disease. We studied comparative effectiveness of treatment plans that involve up to three lines of therapies and impact of treatment sequencing on health and cost outcomes. We employed a Markov model to represent the dynamically changing health status of mCRC patients and used Monte-Carlo simulation to evaluate various treatment plans consistent with existing guidelines. We calibrated our model by a meta-analysis of published data from an extensive list of clinical trials and measured the effectiveness of each plan in terms of cost per quality-adjusted life year. We examined the sensitivity of our model and results with respect to key parameters in two scenarios serving as base case and worst case for patients' overall and progression-free survivals. The derived efficient frontiers included seven and five treatment plans in base case and worst case, respectively. The incremental cost-effectiveness ratio (ICER) ranged between $26,260 and $152,530 when the treatment plans on the efficient frontiers were compared against the least costly efficient plan in the base case, and between $21,256 and $60,040 in the worst case. All efficient plans were expected to lead to fewer than 2.5 adverse effects and on average successive adverse effects were spaced more than 9 weeks apart from each other in the base case. Based on ICER, all efficient treatment plans exhibit at least 87% chance of being efficient. Sensitivity analyses show that the ICERs were most dependent on drug acquisition cost, distributions of progression-free and overall survivals, and health utilities. We conclude that improvements in health outcomes may come at high incremental costs and are highly dependent in the order treatments are administered. PMID- 30288432 TI - Evidenced-Based Claims About Evidence. PMID- 30288433 TI - Implications of True and Perceived Treatment Burden on Cardiovascular Medication Use. AB - : Background: Clinical decisions require weighing possible risks and benefits, which are often based on the provider's sense of treatment burden. Patients often have a different view of how heavily treatment burden should be weighted. Objective: To examine how much small variations in patient treatment burden would influence optimal use of antihypertensive medications and how much over- and undertreatment can result from clinicians misunderstanding their patients' values. Methods: Analysis-Markov chain model. Data sources-Existing literature, including an individual-level meta-analysis of blood pressure trials. Target population-US representative sample, ages 40 to 85, no history of cardiovascular disease. Time horizon-Effect of 10 years of treatment on estimated lifetime quality-adjusted life-year (QALY) burden. Perspective-Patient. OUTCOME MEASURES: QALYs gained by treatment. Results: Fairly small differences in true patient burden from blood pressure treatment alter the number of blood pressure medications that should be recommended and alters treatment's potential benefit dramatically. We also found that a clinician misunderstanding the patient's burden could lead to almost 30% of patients being treated inappropriately. Limitations: Our results are based on simulation modeling. Conclusions: Clinical decisions that fail to account for patient treatment burden can mistreat a very large proportion of the public. Successful treatment choices closely depend on a clinician's ability to accurately gauge a patient's treatment burden. PMID- 30288434 TI - Understanding Midwives' Preferences for Providing Information About Newborn Bloodspot Screening. AB - Background: Understanding preferences for information provision in the context of health care service provision is challenging because of the number of potential attributes that may influence preferences. This study aimed to identify midwives' preferences for the process and outcomes of information provision in an expanded national newborn bloodspot screening program. Design: A sample of practicing midwives completed a hybrid-stated preference survey including a conjoint analysis (CA) and discrete choice experiment to quantify preferences for the types of, and way in which, information should be provided in a newborn bloodspot screening program. Six conjoint analysis questions captured the impact of different types of information on parents' ability to make a decision, and 10 discrete choice experiment questions identified preferences for four process attributes (including parents' ability to make a decision). Results: Midwives employed by the UK National Health Service (n = 134) completed the survey. All types of information content were perceived to improve parents' ability to make a decision except for the possibility of false-positive results. Late pregnancy was seen to be the best time to provide information, followed by day 3 postbirth. Information before 20 weeks of pregnancy was viewed as reducing parents' ability to make a decision. Midwives preferred information to be provided by an individual discussion and did not think parents should receive information on the Internet. Conclusion: A hybrid stated preference survey design identified that a wide variety of information should be provided to maximize parents' ability to make a decision ideally provided late in pregnancy or on day 3 postbirth. PMID- 30288436 TI - Active Choice Intervention Increases Advance Directive Completion: A Randomized Trial. AB - Background. Many people recognize the potential benefits of advance directives (ADs), yet few actually complete them. It is unknown whether an active choice intervention influences AD completion. Methods. New employees were randomized to an active choice intervention (n = 642) or usual care (n = 637). The active choice intervention asked employees to complete an AD, confirm prior AD completion, or fill out a declination form. In usual care, participants could complete an AD, confirm prior completion, or skip the task. We used multivariable logistic regression to assess the relationship between the intervention arm and both AD completion online and the return of a signed AD by mail, as well as assess interactions between intervention group and age, gender, race, and clinical degree status. Results. Participants assigned to the active choice intervention more commonly completed ADs online (35.1% v. 20.4%, P < 0.001) (odds ratio [OR] = 2.10; 95% confidence interval [CI] = 1.63-2.71; number needed to treat = 6.8) and returned signed ADs by mail (7.8% v. 3.9%, P = 0.003; number needed to treat = 25.6). The effect of the intervention was significantly greater among men (OR = 4.13; 95% CI = 2.32-7.35) than among women (OR = 1.74; 95% CI = 1.30-2.32) (interaction P value < 0.001). Responses to all eight choices made in the ADs were similar between groups (all P > 0.10). Limitations. A young and healthy participant may not benefit from AD completion as an older or seriously ill patient would. Conclusions. The active choice intervention significantly increased the proportion of participants completing an AD without changing the choices in ADs. This relationship was especially strong among men and may be a useful method to increase AD completion rates without altering choices. PMID- 30288435 TI - Estimation of Input Costs for a Markov Model in a German Health Economic Evaluation of Newer Antidepressants. AB - Background: Estimating input costs for Markov models in health economic evaluations requires health state-specific costing. This is a challenge in mental illnesses such as depression, as interventions are not clearly related to health states. We present a hybrid approach to health state-specific cost estimation for a German health economic evaluation of antidepressants. Methods: Costs were determined from the perspective of the community of persons insured by statutory health insurance ("SHI insuree perspective") and included costs for outpatient care, inpatient care, drugs, and psychotherapy. In an additional step, costs for rehabilitation and productivity losses were calculated from the societal perspective. We collected resource use data in a stepwise hierarchical approach using SHI claims data, where available, followed by data from clinical guidelines and expert surveys. Bottom-up and top-down costing approaches were combined. Results: Depending on the drug strategy and health state, the average input costs varied per patient per 8-week Markov cycle. The highest costs occurred for agomelatine in the health state first-line treatment (FT) ("FT relapse") with ?506 from the SHI insuree perspective and ?724 from the societal perspective. From both perspectives, the lowest costs (excluding placebo) were ?55 for selective serotonin reuptake inhibitors in the health state "FT remission." Conclusion: To estimate costs in health economic evaluations of treatments for depression, it can be necessary to link different data sources and costing approaches systematically to meet the requirements of the decision-analytic model. As this can increase complexity, the corresponding calculations should be presented transparently. The approach presented could provide useful input for future models. PMID- 30288437 TI - Should We Use the IMPACT-Model for the Outcome Prognostication of TBI Patients? A Qualitative Study Assessing Physicians' Perceptions. AB - Introduction. Shared Decision-Making may facilitate information exchange, deliberation, and effective decision-making, but no decision aids currently exist for difficult decisions in neurocritical care patients. The International Patient Decision Aid Standards, a framework for the creation of high-quality decision aids (DA), recommends the presentation of numeric outcome and risk estimates. Efforts are underway to create a goals-of-care DA in critically-ill traumatic brain injury (ciTBI) patients. To inform its content, we examined physicians' perceptions, and use of the IMPACT-model, the most widely validated ciTBI outcome model, and explored physicians' preferences for communicating prognostic information towards families. Methods. We conducted a qualitative study using semi-structured interviews in 20 attending physicians (neurosurgery,neurocritical care,trauma,palliative care) at 7 U.S. academic medical centers. We used performed qualitative content analysis of transcribed interviews to identify major themes. Results. Only 12 physicians (60%) expressed awareness of the IMPACT model; two stated that they "barely" knew the model. Seven physicians indicated using the model at least some of the time in clinical practice, although none used it exclusively to derive a patient's prognosis. Four major themes emerged: the IMPACT-model is intended for research but should not be applied to individual patients; mistrust in the IMPACT-model derivation data; the IMPACT-model is helpful in reducing prognostic variability among physicians; concern that statistical models may mislead families about a patient's prognosis. Discussion: Our study identified significant variability of the awareness, perception, and use of the IMPACT-model among physicians. While many physicians prefer to avoid conveying numeric prognostic estimates with families using the IMPACT-model, several physicians thought that they "ground" them and reduce prognostic variability among physicians. These findings may factor into the creation and implementation of future ciTBI-related DAs. PMID- 30288439 TI - Comparing and Monitoring Risk-Adjusted Hospital Performance Measures: A Weighted Estimating Equations Approach. AB - Background. There is a great deal of interest in evaluating hospital performance in order to monitor and improve health care quality. Increasingly, risk-adjusted performance measures are available to the public and statistical approaches for estimating these measures are considered. Some methods in use currently are based on 3-year aggregates of data since a small number of cases may lead to imprecise estimates and make it hard for stakeholders to detect differences across hospitals over time. However, if quality changes over time, a measure based on these data is a biased estimate of present performance. Methods. We present an alternative approach (weighted estimating equations [WEE]) for combining historical data in estimation that regulates the tradeoff between bias and precision in the measure of present performance. The WEE approach uses all available historical data through estimating functions that down-weight past data. Results. We compare the WEE approach to two current practices using a realistic dataset of the mortality of patients following an elective percutaneous coronary intervention procedure in New York State who meet certain criteria. The width of the uncertainty interval in the realistic example is up to 65% smaller and the difference is more pronounced for hospitals with a small number of cases. Conclusions. The advantage of this approach extends from the example dataset to other datasets. The WEE approach uses all available data rather than data from an arbitrary 3-year window. The effect of borrowing strength from historical data is a more precise estimate of present performance than current practices. Its advantages are important for the comparison of other aspects of medical performance, including surgical or medical practitioner performance. PMID- 30288438 TI - Access Is Necessary but Not Sufficient: Factors Influencing Delay and Avoidance of Health Care Services. AB - Background: Despite recently expanded access to health insurance, consumers still face barriers to using their coverage to obtain needed health care. Objective: To examine the characteristics of those who delay or avoid health care due to costs. Methods: Participants were recruited via Amazon MTurk and completed a survey assessing demographic characteristics, financial toxicity, health care minimizer maximizer tendencies, health insurance knowledge, numeracy, delaying/avoiding any care, and delaying/avoiding six common health care services (three preventive and three nonpreventive services). Validated measures were used when available. Delay/avoidance behaviors were categorized into delaying/avoiding any care, preventive care, and nonpreventive care. Logistic regression models examined 1) financial toxicity, 2) minimizer-maximizer tendencies, 3) numeracy, 4) health insurance knowledge, and 5) knowledge of preventive care coverage separately on three forms of delay/avoidance behaviors, controlling for chronic conditions, insurance status, and/or income where appropriate. Results: Of 518 respondents, 470 did not fail attention-check questions and were used in analyses. Forty-five percent of respondents reported delaying/avoiding care due to cost. Multivariable analyses found that financial toxicity was related to delaying/avoiding any care (odds ratio [OR] = 0.884, P < 0.001), preventive care (OR = 0.906, P < 0.001), and nonpreventive care (OR = 0.901, P < 0.001). A tendency to minimize seeking health care (OR = 0.734, P < 0.001) and lower subjective numeracy (OR = 0.794, P = 0.023) were related to delaying/avoiding any care. General health insurance knowledge (OR = 0.989, P = 0.023) and knowledge of preventive care coverage (OR = 0.422, P < 0.001) were related to delaying/avoiding preventive care. Conclusions: Many people delay or avoid health care due to costs, even when insured. Results suggest that there may be different reasons individuals delay or avoid preventive and nonpreventive care. Findings may inform interventions to educate consumers and support discussions about health care costs to facilitate appropriate health care utilization. PMID- 30288440 TI - Cost Recommendations in the Second Edition of Cost-Effectiveness in Health and Medicine: A Review. AB - A 2nd edition of Cost-Effectiveness in Health and Medicine has now been published by a group of medical decision-making experts known collectively as the 2nd Panel. This is a critical review of the recommendations for how to deal with costs in cost-effectiveness analysis, recommendations that are contained in Chapter 8 of that edition, titled "Estimating Costs and Valuations of Non-Health Benefits in Cost-Effectiveness Analysis," authored primarily but not exclusively by Anirban Basu. This review focuses on the correspondence between the costs in the numerator of the incremental cost-effectiveness ratio (ICER) and what is measured in the denominator of the ICER by the quality-adjusted life years (QALYs). Although it raises a number of issues regarding what is actually being measured in the numerator and denominator of the ICER, it primarily challenges the 2nd Panel's recommendation that the costs of non-health consumption in any additional years of life generated by the intervention in question be accounted for in the numerator, even though no measures of the benefits are included in the QALYs in the denominator. This review is adapted from a review of the entire 2nd edition that was sent to the 2nd Panel steering committee on January 8, 2016. PMID- 30288441 TI - Individualized Colorectal Cancer Screening Discussions Between Older Adults and Their Primary Care Providers: A Cross-Sectional Study. AB - Introduction. Discussions of colorectal cancer (CRC) screening with older adults should be individualized to maximize appropriate screening. Our aim was to describe CRC screening discussions and explore their associations with patient characteristics and screening intentions. Methods. Cross-sectional survey of 422 primary care patients aged >=70 years and eligible for CRC screening, including open-ended questions about CRC screening discussions. Primary outcomes were the frequency with which CRC screening discussions occurred, who had those discussions, and the domains that emerged from thematic analysis of participants' brief reports of their discussions. We also examined the associations between 1) patient characteristics and whether a screening discussion occurred and 2) the domains discussed and what screening decisions were made. Results. Of 422 participants, 209 reported having discussions and 201 responded to open-ended questions about CRC discussions. In a regression analysis, several factors were associated with increased odds of having a discussion: participants' preference to pursue screening (odds ratio [OR] 2.3, 95% confidence interval [CI] 1.3, 3.9), good health (OR 2.9, 95% CI 1.7, 4.8), and receipt of the decision aid (OR 2.1, 95% CI 1.4, 3.2). Our thematic analysis identified five domains related to discussion content and three related to discussion process. The CRC screening related information domain was the most commonly discussed content domain, and the timing/frequency domain was associated with increased odds of intent to pursue screening. Decision-making role, the most commonly discussed process domain, was associated with increased odds of the intent to forgo CRC screening. Conclusions and Relevance. CRC screening discussions varied by type of participant and content. Future work is needed to determine if interventions focused on specific domains alters the appropriateness of participants' colorectal cancer screening intentions. PMID- 30288442 TI - Organic Dissemination and Real-World Implementation of Patient Decision Aids for Left Ventricular Assist Device. AB - Background. Although patient decision aids (PtDAs) have been shown to improve patient knowledge and satisfaction, they are infrequently used in the real world. We aimed to understand how our publicly available PtDAs developed for destination therapy left ventricular assist device (DT LVAD) were implemented in clinical practice and characterize factors influencing adoption. Methods. We contacted 39 people, 31 who had independently emailed inquiring about our DT LVAD PtDAs and 8 identified through snowball sampling. Thirty people from 23 programs participated in semistructured interviews, which were analyzed using normalization process theory. Results. Eleven programs currently use the PtDAs, 5 plan to use them but have not yet, and 7 do not currently use them nor have active plans to use them. Due to major tradeoffs and preference sensitivity of the DT LVAD decision, participants recognized a role for shared decision making and a need for significant information transfer. Due to a relative lack of resources, participants saw the PtDAs as a way to help facilitate a higher quality decision making process. Limited time, lack of personnel, and perceived burden to implementing system-level change were cited as barriers to use. Initial implementation was accomplished by a champion of the PtDAs. Actual use of the PtDAs most commonly occurred through LVAD coordinators at the start of formal patient teaching sessions, where the PtDAs could be integrated into the existing LVAD consent and education structure. Conclusion. Interest in and implementation of PtDAs occurred independently at several LVAD programs due to a favorable decisional context, including a perceived role for shared decision making in the high-stakes decision around DT LVAD, unmet informational needs, preexisting education sessions, and invested clinical champions. PMID- 30288444 TI - Using a Patient Decision Aid Video to Assess Current and Former Smokers' Values About the Harms and Benefits of Lung Cancer Screening With Low-Dose Computed Tomography. AB - Background. Recent policy changes require discussing the potential benefits and harms of lung cancer screening with low-dose computed tomography. This study explored how current and former smokers value potential benefits and harms after watching a patient decision aid, and their screening intentions. Methods. Current or former smokers (quit within 15 years) with no history of lung cancer watched the decision aid and responded to items assessing the value of potential benefits and harms in their decision making, and their screening intentions. Results. After viewing the decision aid, participants (n = 30; mean age 61.5 years, mean 30.4 pack-year history) were well-informed (mean 80.5% correct responses) and rated anticipated regret and finding cancer early as highly important in their decision (medians >9 out of 10), along with moderate but variable concerns about false positives, overdiagnosis, and radiation exposure (medians 7.0, 6.0, and 5.0, respectively). Most participants (90.0% to 96.7%) felt clear about how they personally valued the potential benefits and harms and prepared for decision making (mean 86.7 out of 100, SD = 21.3). After viewing the decision aid, most participants (90%) intended to discuss screening with their doctor. Limitations. The study is limited to current and former smokers enrolled in a tobacco treatment program, and it may not generalize to other patient populations. Conclusions. The majority of current and former smokers were strongly concerned about anticipated regret and finding cancer early, while concerns about radiation exposure, false positives, and overdiagnosis were variable. After viewing the decision aid, current and former smokers reported strong preparedness and intentions to talk with their doctor about lung cancer screening with low-dose computed tomography. PMID- 30288443 TI - Electronically Verified Use of Internet-Based, Multimedia Decision Aids by Adolescents With Type 1 Diabetes and Their Caregivers. AB - Decision aids (DAs) are central to shared decision making (SDM) interventions, yet little is known about patients' actual DA use. Adequate utilization of DAs could optimize SDM effectiveness. Electronic DAs enable more objective tracking and analysis of actual DA utilization than do paper DAs. This report is part of an ongoing randomized controlled SDM trial enrolling adolescents with type 1 diabetes and their caregivers (n = 153) who were considering use of an insulin pump or continuous glucose monitor. Extensive stakeholder engagement guided creation of two online DAs. After completing baseline measures, 133 dyads were randomized to SDM (access to the pertinent DA) or Usual Care (clinic routines for preparing candidates for adopting these devices). Utilization data showed that 80% of caregivers and 66% of youths logged into a DA at least once; youths and caregivers, respectively, dedicated a mean of 44.7 and 55.0 minutes to website use and viewed 72.2% and 77.4% of the DA content. Median total duration from enrollment to last DA logout was 48.2 days for adolescents and 45.6 days for caregivers. Bivariate comparisons showed that non-Hispanic, Caucasian females from households with higher socioeconomic status were significantly more likely to login to the assigned DA at least once. Hierarchical multiple regression showed that adolescent males with lower levels of health literacy demonstrated fewer DA logins (F = 2.59; P < 0.009), but identified no significant predictors of adolescents' or caregiver' duration of DA use or proportion of DA content viewed. Future SDM trials should seek to promote DA use, especially by non-White adolescents, perhaps with direct assistance with the initial DA login. Trials employing electronic DAs should routinely report and analyze utilization data. PMID- 30288445 TI - Healthy, Wealthy, and Wise? Exploring Parent Comparative Optimism About Future Child Outcomes. AB - Objectives. Comparative optimism is present in parental predictions of their child's long-term, obesity-related health outcomes and some of this optimism is unrealistic. An understanding of how comparative optimism relates to parents' predictions of health versus other child outcomes could contribute to the development of interventions and strategies pediatricians can use to improve risk assessment. Methods. In a nationally representative survey, we asked American parents of 6- to 17-year-old children (n = 410) to estimate the chances that their child and "a typical child in their community" would be affected by overweight, get married, and complete a 4-year college degree by age 30, and the child's future salary at age 30. We collected data on family demographic and health characteristics. We modeled the difference in parent predictions for their child versus the typical child using multivariate linear regressions. Results. Compared to the typical child, parents were less likely to predict that their child would be affected by overweight (-26.6 percentage points, 95% confidence interval [CI]: -35.6, -17.7) and more likely to predict that their child would complete a 4-year degree (16.7 percentage points, 95% CI: 2.5, 31.0). Parents predicted their child would have a higher income than the typical child at age 30 ($15,266, 95% CI: $7,487, $23,046). Parents did not predict that their child would be more likely than the typical child to be married by age 30 (-2.2 percentage points, 95% CI: -8.1, 3.7). Conclusions. Some parents appear to exhibit comparative optimism around their child's future weight status, education, and economic outcomes, but not marriage. Future experimental work should assess whether risk communication approaches that consider optimism bias influence parent risk perception and parenting behaviors. PMID- 30288446 TI - Health Technology Optimization Analysis: Conceptual Approach and Illustrative Application. AB - We present a conceptual approach to determine the optimal solution to delivering a health technology, consistent with the objective of maximizing patient outcomes subject to resources available to a publicly funded health system. The article addresses two key policy questions: 1) adding system values through appropriate planning of health services delivery and 2) considering the tradeoff between patient outcomes and costs to the health system through appropriate use of health technologies for conditions with time-dependent treatment outcomes. We develop a health technology optimization framework that considers geographical variation and searches for the best delivery method through a pairwise comparison of all possible strategies, factoring in controlled variables including disease epidemiology, time or distance to hospitals, available medical services, treatment eligibility, treatment efficacy, and costs. Taking variations of these factors into account would help support a more efficient allocation of health resources. Drawing identified strategies together then creates a map of optimal strategies. We apply the proposed method to a policy-relevant health technology assessment of endovascular therapy (EVT) for treating acute ischemic stroke. The best strategy for providing EVT relies on the geographical location of stroke onset and the decision maker's preference for either patient outcomes or economic efficiency. The proposed method produced an optimization map showing the optimal strategy for EVT delivery, which maximizes patient outcomes while minimizing health system costs. In the illustrative case study, there were no tradeoffs between health outcomes and costs, meaning that the delivery strategies that were clinically optimal for patients were also the most cost-effective. In conclusion, the health technology optimization approach is a useful tool for informing implementation decisions and coordinating the delivery of complex health services such as EVT.

We designed an informatics decision-support tool to facilitate use of the Mayo Clinic Statin Choice decision aid at the point-of-care and evaluated its impact. Methods. Using an iterative approach, we designed and implemented a single-click decision support tool embedded within the electronic health records (EHRs) to automate the calculation of 10-year atherosclerotic cardiovascular disease (ASCVD) risk and populate the Statin Choice decision aid. We surveyed primary care providers at two clinics regarding their attitudes about SDM before and after deployment of intervention, as well as their usage of and perceived competence regarding SDM for primary prevention statin therapy. Three-month web traffic to the Statin Choice website was calculated before and after deployment of the intervention. Results. Pre-post surveys were completed by 60 primary care providers (24 [40%] attending physicians and 36 [60%] housestaff physicians). After deployment of the EHR tool, respondents were more aware of the Statin Choice decision aid (P < 0.001), reported being more competent regarding SDM (P = 0.047), and reported using decision aids more often when considering statin initiation (P = 0.043). There was no significant change in attitudes about SDM as measured through the Patient Provider Orientation Scale (pre 4.23 +/- 0.40 v. post 4.16 +/- 0.38, P = 0.11) and the SDM belief scale (pre 21.4 +/- 2.1 v. post 21.1 +/- 2.0, P = 0.35). Web-based usage rates for the Statin Choice decision aid increased from 3.4 to 5.2 per 1,000 outpatient clinic visits (P = 0.002). Conclusions. Implementation of a point-of-care decision-support tool increased the usage of decision aids for primary prevention statin therapy. This effect does not appear to be mediated by any concomitant changes in physician attitude toward SDM. PMID- 30288448 TI - Population Health and Cost-Effectiveness Implications of a "Treat All" Recommendation for HCV: A Review of the Model-Based Evidence. AB - The World Health Organization HCV Guideline Development Group is considering a "treat all" recommendation for persons infected with hepatitis C virus (HCV). We reviewed the model-based evidence of cost-effectiveness and population health impacts comparing expanded treatment policies to more limited treatment access policies, focusing primarily on evaluations of all-oral directly acting antivirals published after 2012. Searching PubMed, we identified 2,917 unique titles. Sequentially reviewing titles and abstracts identified 226 potentially relevant articles for full-text review. Sixty-nine articles met all inclusion criteria-42 cost-effectiveness analyses and 30 models of population-health impacts, with 3 articles presenting both types of analysis. Cost-effectiveness studies for many countries concluded that expanding treatment to people with mild liver fibrosis, who inject drugs (PWID), or who are incarcerated is generally cost-effective compared to more restrictive treatment access policies at country specific prices. For certain patient subpopulations in some countries-for example, elderly individuals without fibrosis-treatment is only cost-effective at lower prices. A frequent limitation is the omission of benefits and consequences of HCV transmission (i.e., treatment as prevention; risks of reinfection), which may underestimate or overestimate the cost-effectiveness of a "treat all" policy. Epidemiologic modeling studies project that through a combination of prevention, aggressive screening and diagnosis, and prompt treatment for all fibrosis stages, it may be possible to virtually eliminate HCV in many countries. Studies show that if resources are not available to diagnose and treat all HCV-infected individuals, treatment prioritization may be needed, with alternative prioritization strategies resulting in tradeoffs between reducing mortality or reducing incidence. Notably, because most new HCV infections are among PWID in many settings, HCV elimination requires unrestricted treatment access combined with injection transmission disruption strategies. The model-based evidence suggests that a properly constructed strategy that substantially expands HCV treatment could achieve cost-effective improvements in population health in many countries. PMID- 30288450 TI - A Comparison Between Subjective and Objective Methods of Predicting Health Care Expenses to Support Consumers' Health Insurance Plan Choice. AB - Objective. Numerous electronic tools help consumers select health insurance plans based on their estimated health care utilization. However, the best way to personalize these tools is unknown. The purpose of this study was to compare two common methods of personalizing health insurance plan displays: 1) quantitative healthcare utilization predictions using nationally representative Medical Expenditure Panel Survey (MEPS) data and 2) subjective-health status predictions. We also explored their relations to self-reported health care utilization. Methods. Secondary data analysis was conducted with responses from 327 adults under age 65 considering health insurance enrollment in the Affordable Care Act (ACA) marketplace. Participants were asked to report their subjective health, health conditions, and demographic information. MEPS data were used to estimate predicted annual expenditures based on age, gender, and reported health conditions. Self-reported health care utilization was obtained for 120 participants at a 1-year follow-up. Results. MEPS-based predictions and subjective-health status were related (P < 0.0001). However, MEPS-predicted ranges within subjective-health categories were large. Subjective health was a less reliable predictor of expenses among older adults (age * subjective health, P = 0.04). Neither significantly related to subsequent self-reported health care utilization (P = 0.18, P = 0.92, respectively). Conclusions. Because MEPS data are nationally representative, they may approximate utilization better than subjective health, particularly among older adults. However, approximating health care utilization is difficult, especially among newly insured. Findings have implications for health insurance decision support tools that personalize plan displays based on cost estimates. PMID- 30288451 TI - The Lifetime Health Burden of Delayed Graft Function in Kidney Transplant Recipients in the United States. AB - Background. Although delayed graft function (DGF) is associated with an increased risk of acute rejection and decreased graft survival, there are no estimates of the long-term or lifetime health burden of DGF. Objectives. To estimate the long term and lifetime health burden of DGF, defined as the need for at least one dialysis session within the first week after transplantation, for a cohort representative of patients who had their first kidney transplant in 2014. Methods. Data from the United States Renal Data System (USRDS; 2001-2014) were used to estimate a semi-Markov parametric multi-state model with three disease states. Maximum length of follow-up was 13.7 years, and a microsimulation model was used to extrapolate results over a lifetime. The impact of DGF was assessed by simulating the model for each patient in the cohort with and without DGF. Results. At the end of 13.7 years of follow-up, DGF reduces the probability of having a functioning graft from 52% to 32%, increases the probability of being on dialysis from 10% to 19%, and increases the probability of death from 38% to 50% relative to transplant recipients who do not experience DGF. A typical transplant recipient with DGF (median age = 53) is observed to lose 0.87 quality-adjusted life-years (QALYs). Extrapolated over a lifetime, the same 53-year-old DGF patient is projected to lose 3.01 (95% confidence interval: 2.33, 3.70) QALYs relative to a transplant recipient with the same characteristics who does not experience DGF. Conclusions. The lifetime health burden of DGF is substantial. Understanding these consequences will help health care providers weigh kidney transplant decisions and inform policies for patients in the context of varying risks of DGF. PMID- 30288452 TI - Occupational, physical, sexual and mental health and violence among migrant and trafficked commercial fishers and seafarers from the Greater Mekong Subregion (GMS): systematic review. AB - Background: Little is known about the health of GMS commercial fishers and seafarers, many of whom are migrants and some trafficked. This systematic review summarizes evidence on occupational, physical, sexual and mental health and violence among GMS commercial fishers/seafarers. Methods: We searched 5 electronic databases and purposively searched grey literature. Quantitative or qualitative studies reporting prevalence or risk of relevant outcomes were included. Two reviewers independently screened articles. Data were extracted on nationality and long/short-haul fishing where available. Results: We identified 33 eligible papers from 27 studies. Trafficked fishers/seafarers were included in n=12/13 grey literature and n=1/20 peer-reviewed papers. Among peer-reviewed papers: 11 focused on HIV/AIDS/sexual health; nine on occupational/physical health; one study included mental health of trafficked fishers. Violence was quantitatively measured in eight papers with prevalence of: 11-26% in port convenience samples; 68-100% in post-trafficking service samples. Commercial fishers/seafarers whether trafficked or not worked extremely long hours; trafficked long-haul fishers had very limited access to care following injuries or illness. Lesser-known risks reported among fishers included penile oil injections and beriberi. We found just one work safety intervention study and inconclusive evidence for differences in the outcomes by nationality. Findings are limited by methodological weaknesses of primary studies. Conclusion: Results show an absence of high-quality epidemiological studies beyond sexual health. Formative and pilot intervention research on occupational, physical and mental health among GMS commercial fishers and seafarers is needed. Future studies should include questions about violence and exploitation. Ethical and reporting standards of grey literature should be improved.

AB - The sustainability of cobalt is an important emerging issue because this critical base metal is an essential component of lithium-ion batteries for electric vehicles. More than half the world's cobalt mine production comes from the Katanga Copperbelt in DR Congo, with a substantial proportion (estimated at 15 20%) being extracted by artisanal miners. Here we show, in a case study performed in the town of Kolwezi, that people living in a neighbourhood that had been transformed into an artisanal cobalt mine, had much higher levels of cobalt in urine and blood than people living in a nearby control area. The differences were most pronounced for children, in whom we also found evidence of exposure-related oxidative DNA damage. It was already known that industrial mining and processing of metals have led to severe environmental pollution in the region. This field study provides novel and robust empirical evidence that the artisanal extraction of cobalt that prevails in the DR Congo may cause toxic harm to vulnerable communities. This strengthens the conclusion that the currently existing cobalt supply chain is not sustainable. PMID- 30288454 TI - Purinergic Vasotoxicity: Role of the Pore/Oxidant/KATP Channel/Ca2+ Pathway in P2X7-Induced Cell Death in Retinal Capillaries. AB - P2X7 receptor/channels in the retinal microvasculature not only regulate vasomotor activity, but can also trigger cells in the capillaries to die. While it is known that this purinergic vasotoxicity is dependent on the transmembrane pores that form during P2X7 activation, events linking pore formation with cell death remain uncertain. To better understand this pathophysiological process, we used YO-PRO-1 uptake, dichlorofluorescein fluorescence, perforated-patch recordings, fura-2 imaging and trypan blue dye exclusion to assess the effects of the P2X7 agonist, benzoylbenzoyl-ATP (BzATP), on pore formation, oxidant production, ion channel activation, [Ca2+]i and cell viability. Experiments demonstrated that exposure of retinal microvessels to BzATP increases capillary cell oxidants via a mechanism dependent on pore formation and the enzyme, NADPH oxidase. Indicative that oxidation plays a key role in purinergic vasotoxicity, an inhibitor of this enzyme completely prevented BzATP-induced death. We further discovered that vasotoxicity was boosted 4-fold by a pathway involving the oxidation-driven activation of hyperpolarizing KATP channels and the resulting increase in calcium influx. Our findings revealed that the previously unappreciated pore/oxidant/KATP channel/Ca2+ pathway accounts for 75% of the capillary cell death triggered by sustained activation of P2X7 receptor/channels. Elucidation of this pathway is of potential therapeutic importance since purinergic vasotoxicity may play a role in sight-threatening disorders such as diabetic retinopathy. PMID- 30288455 TI - Implementation and Outcomes of a Community-Based Educational Program for Colorectal Cancer Prevention in Hispanics. AB - Objectives: Colorectal cancer (CRC) is the 2nd most diagnosed cancer and leading cause of cancer death in Puerto Rico. However, CRC screening rates remain low. The aim of this study was to test the effectiveness of a Train-the-Trainers' (TTT) program to develop trainers capable of educating others within their communities about CRC prevention. Methods: The TTT program consisted of didactics and seminars to capacitate participants to become trainers in CRC prevention. This project was evaluated using three components: (1) training workshops; (2) community educational sessions; and (3) the participant's experience as a trainer. Pre - and post-tests on CRC screening knowledge were given to TTT participants. Program effectiveness was determined by the pre- and post-tests, number of workshop participants completing a community educational session within three months of training and the number of community members reached. Results: Among the 115 total participants, 97 participants took the pre- and post-test. There was a significant difference in the scores for the pre-test (M = 10.56, SD = 2.57) and the post-test (M = 11.43, SD = 1.83) given; t (96) = -4.68, p < 0.001. A total of 955 community members were reached. Participants from the community educational sessions (n = 680) evaluated the program. 77.7% of those participants expressed intent to undergo colonoscopy screening in the future. Conclusions: TTT was effective in preparing trainers in CRC prevention. Participants increased their knowledge about CRC prevention and successfully reached members of their community. Utilization of community trainers is an effective alternative to increase CRC education and awareness in Hispanic communities, which may positively impact CRC screening rates in this population. PMID- 30288457 TI - Solid-State Effects on the Optical Excitation of Push-Pull Molecular J-Aggregates by First-Principles Simulations. AB - J-aggregates are a class of low-dimensional molecular crystals which display enhanced interaction with light. These systems show interesting optical properties as an intense and narrow red-shifted absorption peak (J-band) with respect to the spectrum of the corresponding monomer. The need to theoretically investigate optical excitations in J-aggregates is twofold: a thorough first principles description is still missing and a renewed interest is rising recently in understanding the nature of the J-band, in particular regarding the collective mechanisms involved in its formation. In this work, we investigate the electronic and optical properties of a J-aggregate molecular crystal made of ordered arrangements of organic push-pull chromophores. By using a time-dependent density functional theory approach, we assess the role of the molecular packing in the enhancement and red shift of the J-band along with the effects of confinement in the optical absorption, when moving from bulk to low-dimensional crystal structures. We simulate the optical absorption of different configurations (i.e., monomer, dimers, a polymer chain, and a monolayer sheet) extracted from the bulk crystal. By analyzing the induced charge density associated with the J-band, we conclude that it is a longitudinal excitation, delocalized along parallel linear chains and that its overall red shift results from competing coupling mechanisms, some giving red shift and others giving blue shift, which derive from both coupling between transition densities and renormalization of the single-particle energy levels. PMID- 30288456 TI - Novel 18F-Labeled PET Imaging Agent FV45 Targeting the Renin-Angiotensin System. AB - Renin-angiotensin system (RAS) plays an important role in the regulation of blood pressure and hormonal balance. Using positron emission tomography (PET) technology, it is possible to monitor the physiological and pathological distribution of angiotensin II type 1 receptors (AT1), which reflects the functionality of RAS. A new 18F-labeled PET tracer derived from the clinically used AT1 antagonist valsartan showing the least possible chemical alteration from the valsartan structure has been designed and synthesized with several strategies, which can be applied for the syntheses of further derivatives. Radioligand binding study showed that the cold reference FV45 (K i 14.6 nM) has almost equivalent binding affinity as its lead valsartan (K i 11.8 nM) and angiotensin II (K i 1.7 nM). Successful radiolabeling of FV45 in a one-pot radiofluorination followed by the deprotection procedure with 21.8 +/- 8.5% radiochemical yield and >99% radiochemical purity (n = 5) enabled a distribution study in rats and opened a path to straightforward large-scale production. A fast and clear kidney uptake could be observed, and this renal uptake could be selectively blocked by pretreatment with AT1-selective antagonist valsartan. Overall, as the first 18F-labeled PET tracer based on a derivation from clinically used drug valsartan with almost identical chemical structure, [18F]FV45 will be a new tool for assessing the RAS function by visualizing AT1 receptor distributions and providing further information regarding cardiovascular system malfunction as well as possible applications in inflammation research and cancer diagnosis. PMID- 30288458 TI - Structure and Dynamics of tRNAMet Containing Core Substitutions. AB - The fidelity of protein synthesis is largely dominated by the accurate recognition of transfer RNAs (tRNAs) by their cognate aminoacyl-tRNA synthetases. Aminoacylation of each tRNA with its cognate amino acid is necessary to maintain the accuracy of genetic code input. Aminoacylated tRNAMet functions in both initiation and elongation steps during protein synthesis. As a precursor to the investigation of a methionyl-tRNA synthetase-tRNAMet complex, presented here are the results of molecular dynamics (MD) for single nucleotide substitutions in the D-loop of tRNAMet (G15A, G18A, and G19A) probing structure/function relationships. The core of tRNAMet likely mediates an effective communication between the tRNA anticodon and acceptor ends, contributing an acceptor stem rearrangement to fit into the enzyme-active site. Simulations of Escherichia coli tRNAMet were performed for 1 MUs four times each. The MD simulations showed changes in tRNA flexibility and long-range communication most prominently in the G18A variant. The results indicate that the overall tertiary structure of tRNAMet remains unchanged with these substitutions; yet, there are perturbations to the secondary structure. Network-based analysis of the hydrogen bond structure and correlated motion indicates that the secondary structure elements of the tRNA are highly intraconnected, but loosely interconnected. Specific nucleotides, including U8 and G22, stabilize the mutated structures and are candidates for substitution in future studies.

AB - A rapid, transition metal-free, high-yielding, tetrabutylammonium bromide promoted method of N-arylation is reported within. The optimized conditions tolerated a wide range of secondary amines and was equally effective with bromo- and chlorobenzene-including substituted aryl halides. The developed method is found to be effective for N-arylation when compared to earlier methods which involve harsh conditions, transition metals, lack of scalability, and long reaction times. Our method utilizes conventional heating only; it is readily scalable; and the products are facile to purify. PMID- 30288461 TI - Musical Instruments As Sensors. AB - The frequencies of notes made by a musical instrument are determined by the physical properties of the instrument. Consequently, by measuring the frequency of a note, one can infer information about the instrument's physical properties. In this work, we show that by modifying a musical instrument to contain a sample and analyzing the instrument's pitch, we can make precision measurements of the physical properties of the sample. We used the mbira, a 3000-year-old African musical instrument that consists of metal tines attached to a wooden board; these tines are plucked to play musical notes. By replacing the mbira's tines with bent steel tubing, filling the tubing with a sample, using a smartphone to record the sound while plucking the tubing, and measuring the frequency of the sound using a free software tool on our website, we can measure the density of the sample with a resolution of about 0.012 g/mL. Unlike existing tools for measuring density, the mbira sensor can be made and used by virtually anyone in the world. To demonstrate the mbira sensor's capabilities, we used it to successfully distinguish diethylene glycol and glycerol, two similar chemicals that are sometimes mistaken for each other in pharmaceutical manufacturing (leading to hundreds of deaths). We also show that consumers could use mbira sensors to detect counterfeit and adulterated medications (which represent around 10% of all medications in low- and middle-income countries). We expect that many other musical instruments can function as sensors and find important and lifesaving applications. PMID- 30288460 TI - Characterization of the Functional Changes in Mouse Gut Microbiome Associated with Increased Akkermansia muciniphila Population Modulated by Dietary Black Raspberries. AB - Gut microbiome plays an essential role in host health through host-gut microbiota metabolic interactions. Desirable modulation of beneficial gut bacteria, such as Akkermansia muciniphila, can confer health benefits by altering microbiome related metabolic profiles. The purpose of this study is to examine the effects of a black raspberry-rich diet to reshape the gut microbiome by selectively boosting A. muciniphila population in C57BL/6J mice. Remarkable changes of the mouse gut microbiome were revealed at both compositional and functional levels with an expected increase of A. muciniphila in concert with a profound impact on multiple gut microbiome-related functions, including vitamin biosynthesis, aromatic amino acid metabolism, carbohydrate metabolism, and oxidative stress. These functional alterations in the gut microbiome by an easily accessed freeze dried black raspberry-supplemented diet may provide novel insights on the improvement of human health via gut microbiome modulation. PMID- 30288462 TI - Synthesis of 2-Azaadamantan-6-one: A Missing Isomer. AB - 2-Azaadamantan-6-one and its Boc and ethylene ketal derivatives were synthesized from 9-oxo endo-bicyclo[3.3.1]non-6-ene-3-carboxylic acid. Similarly, the Cbz, Boc, and ethylene ketal derivatives of 2-azaadamantan-4-one were synthesized from endo-bicyclo[3.3.1]non-6-ene-3-carboxylic acid. Key steps were Curtius rearrangements to form benzyl carbamates, followed by spontaneous intramolecular attack of the carbamate nitrogen on transient bromonium ion or epoxide intermediates to effect ring closure to azaadamantane intermediates. The reaction sequence leading to 2-azaadamantan-6-one is consistent with the formation of a transient tetracyclic keto aziridine intermediate. PMID- 30288463 TI - Approximating Isotope Distributions of Biomolecule Fragments. AB - In mass spectrometry (MS)-based proteomics, protein and peptide sequences are determined by the isolation and subsequent fragmentation of precursor ions. When an isolation window captures only part of a precursor's isotopic distribution, the isotope distributions of the fragments depend on the subset of isolated precursor isotopes. Approximation of the expected isotope distributions of these fragments prior to sequence determination enables MS2 deisotoping, monoisotopic mass calculation, charge assignment of fragment peaks, and deconvolution of chimeric spectra. However, currently such methods do not exist, and precursor isotope distributions are often used as a proxy. Here, we present methods that approximate the isotope distribution of a biomolecule's fragment given its monoisotopic mass, the monoisotopic mass of its precursor, the set of isolated precursor isotopes, and optionally sulfur atom content. Our methods use either the Averagine model or splines, the latter of which have similar accuracy to the Averagine approach, but are 20 times faster to compute. Theoretical and approximated isotope distributions are consistent for fragments of in silico digested peptides. Furthermore, mass spectrometry experiments with the angiotensin I peptide and HeLa cell lysate demonstrate that the fragment methods match isotope peaks in MS2 spectra more accurately than the precursor Averagine approach. The algorithms for the approximation of fragment isotope distributions have been added to the OpenMS software library. By providing the means for analyzing fragment isotopic distributions, these methods will improve MS2 spectra interpretation.

AB - Fentanyl and its derivatives have become pervasive contaminants in the U.S. heroin supply. Previously, we reported a proof-of-concept vaccine designed to combat against heroin contaminated with fentanyl. Herein, we optimized the admixture vaccine and found that it surpassed the individual vaccines in every antinociceptive test, including a 10% fentanyl to heroin formulation. It is anticipated that other co-occurring drug abuse disorders may also be examined with admixture vaccines. PMID- 30288465 TI - Band-Like Charge Transport in Cs2AgBiBr6 and Mixed Antimony-Bismuth Cs2AgBi1-x Sb x Br6 Halide Double Perovskites. AB - Recently, halide double perovskites (HDPs), such as Cs2AgBiBr6, have been reported as promising nontoxic alternatives to lead halide perovskites. However, it remains unclear whether the charge-transport properties of these materials are as favorable as for lead-based perovskites. In this work, we study the mobilities of charges in Cs2AgBiBr6 and in mixed antimony-bismuth Cs2AgBi1-x Sb x Br6, in which the band gap is tunable from 2.0 to 1.6 eV. Using temperature-dependent time-resolved microwave conductivity techniques, we find that the mobility is proportional to T -p (with p ~ 1.5). Importantly, this indicates that phonon scattering is the dominant scattering mechanism determining the charge carrier mobility in these HDPs similar to the state-of-the-art lead-based perovskites. Finally, we show that wet chemical processing of Cs2AgBi1-x Sb x Br6 powders is a successful route to prepare thin films of these materials, which paves the way toward photovoltaic devices based on nontoxic HDPs with tunable band gaps. PMID- 30288466 TI - Covalent Rpn13-Binding Inhibitors for the Treatment of Ovarian Cancer. AB - Substitution of the m,p-chloro groups of bis-benzylidinepiperidone RA190 for p nitro, generating RA183, enhanced covalent drug binding to Cys88 of RPN13. Treatment of cancer cell lines with RA183 inhibited ubiquitin-mediated protein degradation, resulting in rapid accumulation of high-molecular-weight polyubiquitinated proteins, blockade of NFkappaB signaling, endoplasmic reticulum stress, an unfolded protein response, production of reactive oxygen species, and apoptotic cell death. High-grade ovarian cancer, triple-negative breast cancer, and multiple myeloma cell lines were particularly vulnerable to RA183. RA183 stabilized a tetraubiquitin-linked firefly luciferase reporter protein in cancer cell lines and mice, demonstrating in vitro and in vivo proteasomal inhibition, respectively. However, RA183 was rapidly cleared from plasma, likely reflecting its rapid degradation to the active compound RA9, as seen in human liver microsomes. Intraperitoneal administration of RA183 inhibited proteasome function and orthotopic tumor growth in mice bearing human ovarian cancer model ES2-luc ascites or syngeneic ID8-luc tumor. PMID- 30288469 TI - Nuclear Receptors: Opening Up New Avenues of Pediatric Fatty Liver Research. PMID- 30288467 TI - Surface Patterning with SiO2@PNiPAm Core-Shell Particles. AB - Colloidal lithography is a cost-efficient method to produce large-scale nanostructured arrays on surfaces. Typically, colloidal particles are assembled into hexagonal close-packed monolayers at liquid interfaces and deposited onto a solid substrate. Many applications, however, require non close-packed monolayers, which are more difficult to fabricate. Preassembly at the oil/water interface provides non close-packed colloidal assemblies but these are difficult to transfer to a solid substrate without compromising the ordering due to capillary forces acting upon drying. Alternatively, plasma etching can reduce a close packed monolayer into a non close-packed arrangement, however, with limited interparticle distance and compromised particle shape. Here, we present a simple alternative approach toward non close-packed colloidal monolayers with tailored interparticle distance, high order, and retained spherical particle shape. We preassemble poly(N-isopropylacrylamide)-silica (SiO2@PNiPAm) core-shell particles at the air/water interface, transfer the interfacial spacer to a solid substrate, and use the polymer shell as a sacrificial layer that can be thermally removed to leave a non close-packed silica monolayer. The shell thickness, cross-linking density, and the phase behavior upon compression of these complex particles at the air/water interface provide parameters to precisely control the lattice spacing in these surface nanostructures. We achieve hexagonal non close-packed arrays of silica spheres with interparticle distances between 400 and 1280 nm, up to 8 times their diameter. The retained spherical shape is advantageous for surface nanostructuring, which we demonstrate by the fabrication of gold nanocrescent arrays via colloidal lithography and silicon nanopillar arrays via metal-assisted chemical etching. PMID- 30288468 TI - Drug Resistance Mutation L76V Alters Nonpolar Interactions at the Flap-Core Interface of HIV-1 Protease. AB - Four HIV-1 protease (PR) inhibitors, clinical inhibitors lopinavir and tipranavir, and two investigational compounds 4 and 5, were studied for their effect on the structure and activity of PR with drug-resistant mutation L76V (PRL76V). Compound 5 exhibited the best K i value of 1.9 nM for PRL76V, whereas the other three inhibitors had K i values of 4.5-7.6 nM, 2-3 orders of magnitude worse than for wild-type enzymes. Crystal structures showed only minor differences in interactions of inhibitors with PRL76V compared to wild-type complexes. The shorter side chain of Val76 in the mutant lost hydrophobic interactions with Lys45 and Ile47 in the flap, and with Asp30 and Thr74 in the protein core, consistent with decreased stability. Inhibitors forming additional polar interactions with the flaps or dimer interface of PRL76V were unable to compensate for the decrease in internal hydrophobic contacts. These structures provide insights for inhibitor design. PMID- 30288471 TI - Serum HBV RNA is a Potential Predictor of Hepatitis B Surface Antigen Reversion. PMID- 30288470 TI - Adherence to Nucleos(t)ide Analogue Therapies for Chronic Hepatitis B Infection: A Systematic Review and Meta-Analysis. AB - Successful treatment outcomes for chronic hepatitis B virus (HBV) infection requires high levels of adherence to treatment. We searched three databases and abstracts from two conferences up to January 2018 for studies reporting the proportion of patients who were adherent to HBV antiviral therapy and pooled data using random effects meta-analysis. We included 30 studies, providing data for 23,823 patients. Overall, adherence to treatment was 74.6% (95% confidence interval [CI] 67.1%-82.1%). Adherence was similar in high-income settings (75.1%; 95% CI, 65.4%-85.0%) and in low-income and middle-income settings (72.9%; 95% CI, 57.8%-88.0%). Reported barriers to adherence included forgetting, limited understanding of the importance of adherence, and change to routine. Conclusion : There is a need to reinforce assessment and reporting of adherence as a routine part of HBV care and to assess the extent to which evidence-based interventions to improve adherence to medication for human immunodeficiency virus [HIV] and other chronic diseases are effective for HBV infection. PMID- 30288472 TI - Acute Kidney Injury in Patients Undergoing Chronic Hepatitis C Virus Treatment With Ledipasvir/Sofosbuvir. AB - Ledipasvir-sofosbuvir, a once-a-day, oral combination pill, was approved in 2014 for the treatment of chronic hepatitis C infection. Initial trials did not comment on nephrotoxicity; however, recent data suggest a risk of acute kidney injury (AKI) with the use of the medication. We assessed the rates of AKI in patients undergoing ledipasvir-sofosbuvir in a large, urban tertiary care center. This single-center retrospective observation study included all patients undergoing therapy from October 1, 2014, to October 1, 2015. Rates of AKI, defined by more than a 0.3 mg/dL increase in serum creatinine level, were calculated. Patients were followed 12 weeks after therapy to assess for sustained viral response as well as to assess for improvement of AKI after completion of therapy, defined by less than 0.2 mg/dL above baseline serum creatinine. In total, 197 patients were included in the final analysis who had completed ledipasvir-sofosbuvir therapy and completed laboratory values. Among the patients treated, 38 (19%) had AKI during therapy. An additional 4 (2%) had AKI at the end of therapy. Of the 38 patients who experienced AKI, 20 (53%) had improvement in serum creatinine to less than 0.2 mg/dL above their baseline. When comparing for chronic kidney disease (CKD) stage, those with CKD I or II experienced AKI 17% of the time compared with 47% of the time in CKD III or worse (P = 0.005). Conclusion: AKI was seen in nearly one-fifth of our patients, and patients with CKD stage III or worse are at increased risk. Although ledipasvir-sofosbuvir is generally safe in the general population, close monitoring of renal function is recommended.

The onset of acute hepatitis rose two weeks after starting treatment with LDV/SOF when HCV-RNA tested negative, suggesting a link between rapid HCV clearance and de novo autoimmune diseases. Conclusion: This case report proposes new immunologic scenarios in patients with hepatitis C virus (HCV) with laboratory or clinical signs of autoimmunity during direct-acting antiviral (DAA) therapy. PMID- 30288475 TI - Reactive Ductules Are Associated With Angiogenesis and Tumor Cell Proliferation in Pediatric Liver Cancer. AB - While reactive ductules (RDs) have been observed in viral hepatitis, biliary atresia, nonalcoholic fatty liver disease, and adult hepatocellular carcinoma (HCC), RDs in pediatric liver cancer remain uncharacterized. This study investigated the relationship of RDs with angiogenic paracrine factors, the extent of angiogenesis, and tumor cell proliferation in pediatric hepatoblastoma (HBL)/HCC livers. We quantified the extent of RDs and their expression of paracrine factors that include vascular endothelial growth factor (VEGF), vascular endothelial growth factor D (VEGFD), platelet-derived growth factor C, and angiopoietin 1 (ANGPT1). In addition, we performed immunohistochemical detection of the endothelial marker clusters of differentiation (CD)34 and the proliferation marker Ki67 followed by correlation analyses. In HBL, we found the percentage of RDs with Ki67 expression (% Ki67+ RDs) significantly correlated with intratumoral Ki67+ areas (r = 0.5138, P = 0.0349) and % ANGPT1+ RDs positively correlated with % Ki67+ RDs (r = 0.5851, P = 0.0136). In HCC, the high ANGPT1+ RDs group (i.e., cases with % ANGPT1+ RDs >=50) exhibited high intratumoral Ki67+ areas compared to the low ANGPT1+ RDs group. In the combined HBL and HCC liver tumor group, there was a positive association between % platelet-derived growth factor C+ RDs and intratumoral Ki67+ areas (r = 0.4712, P = 0.0099) and the high VEGFD+ RDs group (>=50%) exhibited a high number of peritumoral CD34+ vessels compared to the low VEGFD+ RDs group. Conclusion: Paracrine factor-expressing RDs are associated with angiogenesis and proliferation of pediatric liver tumors. PMID- 30288474 TI - Placebo-Controlled Randomized Trial of an Intestinal Bile Salt Transport Inhibitor for Pruritus in Alagille Syndrome. AB - Medically refractory, severe, cholestasis-induced pruritus in Alagille syndrome may be improved by surgical interruption of the enterohepatic circulation. This multicenter trial (NCT02057692) tested the hypothesis that the intestinal bile acid transport inhibitor maralixibat would similarly reduce pruritus in Alagille syndrome. Thirty-seven children with Alagille syndrome were randomly assigned to double-blinded administration of placebo, 70, 140, or 280 ug/kg/day of maralixibat for 13 weeks. Pruritus was assessed by caregiver (itch-reported outcome instrument [ItchRO]) and clinician report (range, 0-4 [severe]). Liver chemistries and serum bile acids were measured. The primary outcome was the change from baseline to week 13 in ItchRO relative to placebo. In the a priori first analysis of the primary efficacy endpoint, the mean adjusted difference between participants receiving 140 or 280 ug/kg/day and placebo was -0.47 (95% confidence interval [CI], -1.14, 0.20; P = 0.16). Statistically significant decreases were observed with doses of 70 and 140 ug/kg/day (mean adjusted difference, -0.89; 95% CI, -1.70, -0.08; P = 0.032; and mean adjusted difference, -0.91; 95% CI, -1.62, -0.19; P = 0.014) but not 280 ug/kg/day (mean adjusted difference, -0.04; 95% CI, -0.94, 0.86; P = 0.44) or all doses combined (mean adjusted difference, -0.61; 95% CI, -1.24, 0.20; P = 0.055). A 1-point reduction in pruritus was more common in maralixibat-treated versus placebo-treated participants (caregiver ItchRO, 65% versus 25%; P = 0.06; clinician score, 76% versus 25%; P = 0.01). There were no significant changes in liver chemistries or bile acids relative to placebo. Adverse and serious adverse events were similar between maralixibat and placebo. Conclusion: Although the prespecified primary analyses of ItchRO were not all statistically significant, the data suggest that maralixibat is safe and may reduce pruritus in Alagille syndrome. PMID- 30288477 TI - Among Patients With NAFLD, Treatment of Dyslipidemia Does Not Reduce Cardiovascular Mortality. AB - Dyslipidemia is one of the common risk factors for NAFLD and is associated with cardiovascular (CV) mortality, which is the most common cause of death in NAFLD. Lipid-lowering agents (LLAs) are used to reduce CV events in the general population. Our aim was to assess whether the use of LLAs in patients with NAFLD can reduce the risk of CV mortality. We used the third National Health and Nutrition Examination Survey mortality linked files. Mortality was determined from the National Death Index records through 2011. NAFLD was diagnosed by ultrasound after exclusion of other causes of liver disease. After inclusion and exclusion, the cohort consisted of 2,566 patients with NAFLD (45.8% < 45 years of age, 52.8% male, 75.4% white). Those who were taking LLAs were more likely to be older, non-Hispanic white, and had significantly higher rates of diabetes mellitus (DM), hyperlipidemia, hypertension, metabolic syndrome, and history of CV disease (CVD) (all P< 0.01). In our multivariate analysis, DM was an independent predictor of overall mortality (adjusted hazard ratio [aHR]: 1.79 [95% confidence interval (CI): 1.40-2.30]) and CV mortality (aHR: 1.89 [95% CI: 1.08-3.30]). History of CVD was associated with both overall (aHR: 2.03 [95% CI: 1.57-2.63]) and CV mortality (aHR: 3.69 [95% CI: 2.23-6.08]). In contrast, the use of statins and other LLAs was not associated with reduction in overall (aHR = 0.95 [95% CI: 0.37-2.44] and aHR = 1.43 [95% CI: 0.99-2.07]) and CV mortality (aHR = 1.20 [95% CI: 0.26-5.54] and aHR = 1.63 [95% CI: 0.70-3.76]). Conclusion: The use of statins and other LLAs did not reduce the increased risk of overall or CV mortality in NAFLD. PMID- 30288476 TI - Hepatic Nuclear Receptor Expression Associates with Features of Histology in Pediatric Nonalcoholic Fatty Liver Disease. AB - Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in children and adults. This study examined the relationship between hepatic nuclear receptor (NR) expression and histologic features of NAFLD. Drugs targeting a variety of NRs for nonalcoholic steatohepatitis (NASH) are in clinical trials. Liver messenger RNA was isolated from 40 children (10-19 years) undergoing end-of-treatment biopsy in the Treatment of NAFLD in Children (TONIC) trial. High-throughput quantitative polymerase chain reaction assayed NR messenger RNA. Cluster analysis was used to group 36 NRs, and NR levels were related to histologic measures of specific NAFLD features. Cluster analysis determined five groupings of NRs. Significant (P < 0.05) differential expressions of specific NRs associated with histologic measures include farnesoid X receptor alpha and retinoic acid receptor (RARbeta and RARbeta) for steatosis; estrogen receptor alpha (ERalpha) and peroxisome proliferator-activated receptor gamma 3 (PPARgamma3) for hepatocellular ballooning; ER and PPARgamma2 for lobular inflammation; PPARalpha/delta/gamma1/gamma2, ERalpha, constitutive androstane receptor, chicken ovalbumin upstream promoter transcription factor 1, RARalpha, RARbeta1, retinoid X receptor, pregnane X receptor, thyroid hormone receptors alpha and beta, and nuclear receptor related-1 for fibrosis; and ERalpha and RARbeta/beta1/alpha for diagnosis of NASH. Conclusion: Differential expression of specific NRs correlates with histologic severity of specific NAFLD features. These NRs are pleiotropic transactivators regulating basal metabolic functions and inflammatory responses. Derangement of activity of these receptors in NAFLD provides a rationale for exploiting their ability with receptor-specific ligands to ameliorate NASH and its consequences. PMID- 30288478 TI - CEACAM1 Is Associated With the Suppression of Natural Killer Cell Function in Patients With Chronic Hepatitis C. AB - Natural killer cells (NK cells) play an essential role in the immunological mechanism underlying chronic hepatitis C (CHC). Impairment of NK cell function facilitates persistent infection with hepatitis C virus (HCV) and hepatocellular carcinogenesis. However, the mechanism by which NK cell activity is suppressed in CHC is not completely understood. In this study, we focused on carcinoembryonic antigen-related cell-adhesion molecule 1 (CEACAM1). CEACAM1 is thought to suppress NK cell function. We examined the effect of CEACAM1 on NK cell function in CHC. We investigated the function of CEACAM1 in vitro using Huh7.5.1 cells and the HCV-Japanese fulminant hepatitis (JFH)-1 strain. We analyzed serum CEACAM1 level, NK cell function, and CEACAM1 messenger RNA (mRNA) level in human liver samples. Levels of CEACAM1 on the cell surface, CEACAM1 mRNA levels, and soluble CEACAM1 levels in supernatants were significantly higher in Huh7.5.1 cells infected with JFH-1 (Huh7.5.1/JFH-1 cells) than in Huh7.5.1 cells. Significantly higher NK cell cytotoxicity was observed toward K562 cells after coculture with CEACAM1 knockout Huh7.5.1/JFH-1 cells than after coculture with Huh7.5.1/JFH-1 cells. CEACAM1 expression was induced by the HCV E2 glycoprotein in HCV infection. Significantly higher serum CEACAM1 levels were detected in patients with CHC compared with healthy subjects and patients who achieved sustained virological responses. The expression of CD107a on NK cells from patients with CHC was negatively correlated with serum CEACAM1 levels. Significantly higher levels of CEACAM1 mRNA were detected in HCV-infected livers compared with uninfected livers. Conclusion: CEACAM1 expression was induced in hepatocytes following HCV infection and decreased NK cell cytotoxicity. These results demonstrate a possible role for CEACAM1 in the pathogenesis of CHC and hepatocellular carcinoma progression. PMID- 30288479 TI - Micro RNA-4651 Serves as a Potential Biomarker for Prognosis When Selecting Hepatocellular Carcinoma Patients for Postoperative Adjuvant Transarterial Chemoembolization Therapy. AB - Our previous reports have shown that microRNA-4651 is a potential early diagnostic and prognostic marker for hepatocellular carcinoma. We aimed to investigate whether microRNA-4651 modified postoperative adjuvant transarterial chemoembolization (pa-TACE) to improve the prognosis of hepatocellular carcinoma. A hospital-based retrospective study, including 302 patients with advanced-stage hepatocellular carcinoma who received tumor resection or tumor resection plus pa TACE as an initial therapy, was conducted to assess the effects of microRNA-4651 on pa-TACE treatment. MicroRNA-4651 expression in tumor tissues was tested using the TaqMan-PCR technique. The sensitivity of tumor cells to doxorubicin (an anticancer drug used in pa-TACE procedure) was analyzed by the half-maximal inhibitory concentration (IC50). Upregulated microRNA-4651 expression in tumor tissues can improve the therapeutic response of patients with hepatocellular carcinoma on pa-TACE (hazard ratios [95% confidence intervals] = 0.32 [0.22-0.46] for death risk and 0.39 [0.28-0.56] for tumor-recurrence risk, respectively), but downregulated expression cannot. Functional analyses-displayed microRNA-4651 mimics decreased while its inhibitor increased the IC50 of tumor cells to doxorubicin (0.65 [0.61-0.69] versus 2.17 [1.98-2.37] uM). Cytochrome P450 2W1 was shown as a possible target of microRNA-4651. Additionally, dysregulation of microRNA-4651 also affected the clinical pathological features of hepatocellular carcinoma and was an independent prognostic factor for this cancer. Conclusion: These results indicate that increasing microRNA-4651 expression may be beneficial for pa-TACE in improving hepatocellular carcinoma prognosis. PMID- 30288480 TI - Liver Disease Monitoring Practices After Hepatitis C Cure in the Underserved Population. AB - Recent hepatitis C virus (HCV) guidelines recommend disease monitoring and hepatocellular carcinoma (HCC) screening in patients with advanced fibrosis after a sustained virologic response (SVR) with direct-acting antiviral (DAA) therapy. However, data on practice patterns in this setting is lacking. We aimed to characterize disease monitoring and HCC screening practices post-SVR in an underserved HCV-infected cohort. Records of 192 patients who received DAA therapy at the San Francisco safety-net health care system between January 2014 and January 2016 with >=12 months of follow-up post-SVR were reviewed. Patient characteristics were median age 58 years, 61.5% men, 39.1% White (23.4% Black, 16.7% Latino, 16.2% Asian), 78.1% English proficient, 48.9% intravenous drug use, 53.2% alcohol use, and 41% advanced (F3 and F4) fibrosis (26.6% with decompensation, 11.4% with HCC). Median post-SVR follow-up time was 22 months. A higher proportion of patients with advanced fibrosis attended liver clinic visits (mean, 1.94 +/- 2.03 versus 1.12 +/- 1.09 visits; P = 0.014) and had liver imaging (41.4% versus 9.73%; P < 0.001) post-SVR, but there was no difference in alanine aminotransferase (ALT) testing (72.2% versus 66.4%; P = 0.40) compared to those without advanced fibrosis. However, 20% with advanced fibrosis had no HCC screening while 35% with no advanced fibrosis had liver imaging. Three patients with cirrhosis developed new HCC. Conclusion: Although the majority of patients with advanced fibrosis in this underserved cohort received post-SVR monitoring, gaps in HCC screening were identified and new cases of HCC occurred during a short follow-up. This highlights the importance of incorporating recently enhanced guidelines to optimize post-SVR monitoring, especially in difficult to engage populations. PMID- 30288481 TI - Serum Anti-Mullerian hormone and embryo morphokinetics detecting by time-lapse imaging: A comparison between the polycystic ovarian syndrome and tubal factor infertility. AB - Background: Anti-Mullerian hormone (AMH) is considered as a good marker for quantitative evaluation of ovarian response to the stimulation during assisted reproductive technology cycles. Objective: To evaluate the association between serum AMH level and embryo morphokinetics using time-lapse imaging and intracytoplasmic sperm injection (ICSI) outcomes in women with polycystic ovarian syndrome (PCOS). Materials and Methods: We evaluated a total of 547 embryos from 100 women underwent ICSI cycles; 50 women with PCOS and 50 women with tubal factor infertility. Serum AMH level was measured in all participants. Time-laps records were annotated for time to pronuclear fading (tPNf), time to 2-8 cells (t2-t8), reverse cleavage, direct cleavage, and also for the presence of multinucleation. Results: AMH was negatively correlated with t5, t8, and the third cell cycle (p=0.02, p=0.02, and p=0.01; respectively) in PCOS group. AMH had no correlation with embryo kinetics in infertile women with tubal factor infertility. Moreover, AMH level is similar between embryos with and without direct cleavage as well as reverse cleavage and Multinucleation in both groups. The Receiver operating characteristic curves analyses indicated that AMH was not an accurate predictor of clinical pregnancy as well as a live birth (AUC=0.59 [95% CI, 0.42-0.76]) in PCOS women. However, in the women with tubal factor infertility AMH showed a fair prediction value for clinical pregnancy (AUC=0.64 [95% CI, 0.48-0.82]) along with the live birth (AUC=0.70 [95% CI, 0.55-0.85]). Conclusion: Some of the time-lapse embryo parameters may be related to the AMH concentration. However, AMH is not an accurate tool to predict the ICSI outcomes in PCOS women. PMID- 30288482 TI - The frequency of TP53 R72P and MDM2 309T>G polymorphisms in Iranian infertile men with spermatogenetic failure: A case-control study. AB - Background: Tumor protein p53 (TP53) is a tumor suppressor transcriptional regulator protein which plays a critical role in the spermatogenesis. One of the most important regulators of p53 is Murine double minute 2 (MDM2), which acts as a negative regulator of the p53 pathway. Based on the key role of p53 and MDM2 in germ cell apoptosis, polymorphisms that cause a change in their function might affect germ cell apoptosis and the risk of male infertility. Objective: This study was designed to examine associations of TP53 72 Arg>Pro (rs1042522), and MDM2 309 T>G (rs937283) polymorphisms with spermatogenetic failure in Iranian population. Materials and Methods: A case-control study was conducted with 150 nonobstructive azoospermia or severe oligozoospermia and 150 fertile controls. The two polymorphisms, 72 Arg>Pro in TP53 and 309 T>G in MDM2, were genotyped using PCR-RFLP and ARMS-PCR respectively. Results: Our analyses revealed that the allele and genotype frequencies of the TP53 R72P polymorphism were not significantly different between the cases and controls (p=0.41, p=0.40 respectively). Also, no significant differences were found in the allelic (p=0.46) and genotypic (p=0.78) distribution of MDM2 309 T>G polymorphism between patients and controls. Conclusion: The results of this study indicate that polymorphisms of TP53 and MDM2 genes are unlikely to contribute to the pathogenesis of male infertility with spermatogenetic failure. PMID- 30288483 TI - Antioxidant homeostasis is disturbed in fetuses with leptin-resistant genotypes: A cross-sectional study. AB - Background: Leptin resistance is associated with lower reproductive efficiency, with deficiencies in embryo viability and growth leading to low prolificacy and high incidence of intrauterine growth restriction. Objective: We aimed to investigate the underlying mechanisms of the leptin-resistance, evaluating the antioxidant homeostasis of leptin-resistant and lean swine fetuses. Materials and Methods: The study included 70 plasma samples from fetuses at day 62 of gestation (mid-pregnancy), from breeds with (Iberian breed; n=35) and without leptin resistance (25% Large White x 25% Landrace x 50% Pietrain; n=35). The antioxidant status of the plasma samples was determined by photoinduced chemiluminescence whilst systemic oxidative stress was assessed determining plasma hydrogen peroxide concentration by enzimoimmunoassay. Results: Plasma total antioxidant capacity was significantly lower in leptin-resistant fetuses (p=0.003), whilst systemic oxidative stress was increased (p=0.02). Conclusion: Our results indicate key differences in the antioxidant status in pregnancies affected by leptin resistance. PMID- 30288484 TI - The relationship between the expression levels of miR-135a and HOXA10 gene in the eutopic and ectopic endometrium. AB - Background: The study of microRNA expression can be effective in the diagnosing and treating different diseases. miR-135a is one of the most important micro ribonucleic acids involved in endometriosis. Among the genes that become the target of the miR-135a and are subjected to changes in the endometrium of patients with endometriosis is HOXA10 gene which is expressed in the endometrium in response to steroid hormones. Objective: The aim of this study was to evaluate the expression of miR-135a and its relationship with the level of HOXA10 gene expression in both endometrial ectopic and eutopic tissues in patients with endometriosis compared to the control samples. Materials and Methods: In this prospective case-control study, both case-eutopic and case-ectopic tissue samples were obtained from 17 women with endometriosis and the eutopic endometrial tissue was sampled from 17 women with normal endometrium as the control group. The gene's expression of miR-135a and HOXA10 were investigated using quantitative reverse transcription PCR (q-RT PCR). Results: A significant decrease in the expression of HOXA10 gene was detected in case-eutopic during the luteal phase compared to the control samples (p=0.001), while in the case-ectopic, the expression of this gene was increased (p=0.681) compared to the control samples. In addition, the expression miR-135a in the luteal phase showed a remarkable increase in the case-eutopic endometrial tissue (p=0.026) as well as a significant decrease in the case-ectopic endometrial tissue compared to the control samples (p=0.008). Conclusion: Considering the inverse relations between the over-expression of miR-135a and the reduction of HOXA10, it seems that miR 135a may be applied as an endometrial diagnostic and therapeutic biomarker. PMID- 30288485 TI - Evaluation of specific germ cell genes expression in mouse embryonic stem cell derived germ cell like cells treated with bone morphogenetic protein 4 in vitro. AB - Background: Bone morphogenetic protein 4 (BMP4) is a significant signaling molecule that involves in initiating of differentiation and performs multifunctional effects on embryonic stem cells (ESCs) and embryos. Objective: The goal of the present study was to evaluate an in vitro differentiation model of mouse embryonic stem cells into germ cells, using BMP4. Materials and Methods: in this experimental study, we used Oct4-GFP mouse ESCs to form embryoid body (EB) aggregations for two days. Then, single cells from EB were cultured for four days with BMP4. Using MTT assay and gene expression levels for evaluation of Mvh and Riken by real-time RT-PCR of six concentrations, 12.5 ng/ ml BMP4 was determined as an optimized dose. Then, the expression level of Fkbp6, Mov10l1, 4930432K21Rik, Tex13, Mvh, Scp3, Stra8, Oct4 were evaluated. Flow cytometry and immunostaning were used to confirm the findings of the real-time RT-PCR. Results: In the +BMP4 group, the genes encoding Riken (p<=0.001) and Mvh (p<=0.001) were found to be increased with significant differences compared with the control group. Mov10l1 (p=0.22), Tex13 (p=0.10), Fkbp6 (p=0.90), Scp3 (p=0.61) and Stra8 (p=0.08) were up-regulated without significance differences compared with control group. Flow cytometry analysis showed that the mean number of Mvh-positive cells in the +BMP4 group was greater when compared with ESCs, -BMP4 and EB groups (p=0.03, p<=0.001, p=0.02, respectively). Conclusion: Down-regulation of Oct4, expression of germ cells genes and meiosis markers expression raise this hypothesis that ESCs were differentiated by BMP4, and may be introduced into the first meiosis as germ cell-like cells. PMID- 30288486 TI - The effect of crocin on testicular tissue and sperm parameters of mice offspring from mothers exposed to atrazine during pregnancy and lactation periods: An experimental study. AB - Background: Atrazine as a herbicide may affect the human's health. Crocin may protect atrazine-induced damages. Objective: The aim of this study was to evaluate the effects of atrazine on mice testicular tissue and sperm parameters and protective effects of Crocin on probably atrazine-induced damages. Materials and Methods: in this experimental study, 24 pregnant Balb/c mice were randomly divided to 4 groups: I: Atrazine (10 mg/kg), II: Atrazine-Crocin, III: Crocin (10mg/kg) and IV: Normal saline. Administrations were done daily by gavage during pregnancy and lactation. In the end, two male offspring were randomly selected from every mother and sacrificed respectively on 23 and 75 postnatal days. Then, their epididymides were removed for sperm parameters investigation and their testes were prepared to evaluate apoptosis by means of TUNEL technique. Results: The mean number of sperms in the atrazine group was lower compared to other groups and increased in the atrazine-crocin group compared with atrazine group significantly (p=0.001). Sperm abnormality was increased in the atrazine group compared with the normal saline group and decreased in the atrazine-crocin group compared with atrazine group significantly (p<=0.001). TUNEL-positive spermatogonia in 23 days old offspring increased significantly in the atrazine group compared with other groups (p=0.03). TUNEL-positive spermatogenic cells in 75 days old offspring was significantly increased in the atrazine group compared with the saline group (p<=0.001). Conclusion: Atrazine exposure may lead to decrease the number of sperms, increase sperms abnormality, spermatogenic cell apoptosis and height of germinal epithelium. These complications may improve by crocin administration. PMID- 30288487 TI - Influence of body mass index and polycystic ovarian syndrome on ICSI/IVF treatment outcomes: A study conducted in Pakistani women. AB - Background: Obesity may establish a crucial barrier for effective fertility treatment in polycystic ovary syndrome (PCOS) females. Objective: To compare results of intra-cytoplasmic sperm injection (ICSI) in females with and without polycystic ovarian syndrome and further appraise the effect of obesity in PCOS females. Materials and Methods: A cross-sectional study from June 2015 to July 2016 included non-PCOS and PCOS (recognized by Rotterdam criteria) females who underwent ICSI. The PCOS were further stratified into non-obese and Obese according to the South Asian criteria for body mass index. Results were categorized on the basis of beta-human chorionic gonadotropin (beta-hCG) and transvaginal scan into non-pregnant (beta-hCG <25 mIU/ml), preclinical abortion (beta-hCG >25 mIU/ml with no fetal cardiac activity) and clinical pregnancy (beta hCG >25 mIU/ml with fetal cardiac activity on transvaginal scan). In addition, reproductive outcomes; implantation rate, clinical pregnancy rate and miscarriage rate among obese and non-obese PCOS and non-PCOS patients were compared. Results: Our results revealed 38.5% clinical pregnancy rate in non-PCOs females, 23.8% in non-obese PCOS females whereas 26.4% in obese PCOS. Preclinical abortions were found to be highest (31.5%) in non-obese PCOS females and were the lowest (26.2%) in non-PCOS females. In non-PCOS group and non-obese PCOS females 35.4% and 44.6%, respectively, failed to become pregnant. Conclusion: The success after ICSI in terms of number of clinical pregnancies was more in non-PCOS patients as compared to PCOS. Increase in body mass index reflected a negative impact on the reproductive outcome in PCOS patients. PMID- 30288488 TI - Comparison of pre-treatment with OCPs or estradiol valerate vs. no pre-treatment prior to GnRH antagonist used for IVF cycles: An RCT. AB - Background: Both oral contraceptive pills (OCPs) and estradiol valerate (E2) have been used to schedule a gonadotropin-releasing hormone antagonist in vitro fertilization (IVF) cycles. Since the suppression of follicle-stimulating hormone by OCPs can stay 5-7 days after stopping the pills, it seems that starting the gonadotropin-releasing hormone (GnRH) after 6 days of pre-treatment discontinuation may be important in IVF outcomes. Objective: The aim of the present study was to determine the number of mature oocyte and pregnancy rate of three pretreatment methods for fresh embryo transfer cycles. Materials and Methods: In this randomized controlled trial, two-hundred ten women (18-35 yr and less than 2 previous IVF attempts) undergoing IVF with the GnRH antagonist protocol were randomized to the OCP, E2, and no pretreatment arms. OCP group (n=53) received OCP (ethinyl estradiol30 MUg and levonorgestrel150 MUg), E2 group (n=63) received 4 mg/day oral E2 (17beta-E2) for 10 days from day 20 of the previous cycle and GnRH antagonist stimulation was started 6 days after the interruption of OCP and E2. The control group (n =70) did not receive any pretreatment. Results: No significant difference was observed in the mean number of the mature oocyte, endometrial thickness, and embryo quality. The pregnancy rate in E2 group was higher than the two other groups (42.9% vs 39.6% and 34.3% in OCP and control group, respectively), but the difference was not statistically significant (p=0.59). Conclusion: It seems OCP or E2 pretreatment could not improve the fresh IVF-embryo transfer outcomes.

PMID- 30288490 TI - Drastic Improvement of Air Stability in an n-Type Doped Naphthalene-Diimide Polymer by Thionation. AB - Organic thermoelectrics are attractive for the fabrication of flexible and cost effective thermoelectric generators (TEGs) for waste heat recovery, in particular by exploiting large-area printing of polymer conductors. Efficient TEGs require both p- and n-type conductors: so far, the air instability of polymer n-type conductors, which typically lose orders of magnitude in electrical conductivity (sigma) even for short exposure time to air, has impeded processing under ambient conditions. Here we tackle this problem in a relevant class of electron transporting, naphthalene-diimide copolymers, by substituting the imide oxygen with sulfur. n-type doping of the thionated copolymer gives rise to a higher sigma with respect to the non-thionated one, and most importantly, owing to a reduced energy level of the lowest-unoccupied molecular orbital, sigma is substantially stable over 16 h of air exposure. This result highlights the effectiveness of chemical tuning to improve air stability of n-type solution processable polymer conductors and shows a path toward ambient large-area manufacturing of efficient polymer TEGs. PMID- 30288491 TI - Risk-Reducing Options for Women with a Hereditary Breast Cancer Predisposition. AB - Genetic testing is now widely utilized to identify women with a hereditary predisposition for breast cancer. Women who carry mutations that increase breast cancer risk may consider three options to reduce risk: screening, chemoprevention, and prophylactic surgery. Yet, no randomized trials have specifically assessed the efficacy of these options in mutation carriers. In many developed countries, mammography is regarded as the optimal means of screening for breast cancer in the general population. However, breast MRI is a more sensitive screening tool, and for mutation carriers, any breast cancer screening strategy should incorporate screening with MRI. In randomized trials of women at high risk for developing breast cancer, chemoprevention reduces that risk, but it has not been shown to reduce mortality. Finally, observational studies suggest that, in mutation carriers, prophylactic surgery may reduce the risk of developing breast cancer by 90-95%. There are several prophylactic mastectomy procedures to choose from, and these are generally done in conjunction with breast reconstruction. In this article, we discuss management of women who carry mutations that have been associated with an increased breast cancer risk. Mutation carriers should be informed of the potential risks and benefits of the three available options to reduce breast cancer risk. PMID- 30288492 TI - QOL Evaluation of Nab-Paclitaxel and Docetaxel for Early Breast Cancer. AB - Objective: A previous randomized phase II study showed that neoadjuvant nab paclitaxel (nab-PTX) 100 mg/m2) was effective and well-tolerated in patients with HER2-negative early-stage breast cancer, compared with docetaxel (DTX). We evaluated patient outcomes in terms of the Functional Assessment of Cancer Therapy-Breast (FACT-B), as a measure of health-related quality of life (HRQoL). Materials and Methods: Stage I-III HER2-negative breast cancer patients from the previous study were included. They received either four cycles of nab-PTX (100 mg/m2 days 1/8/15) every 4 weeks, or DTX (75 mg/m2 day 1) every 3 weeks, both followed by four cycles of 5-fluorouracil/epirubicin/cyclophosphamide (FEC). Patients completed a health-related quality-of-life questionnaire at baseline, after one and four cycles of taxanes, before administration of FEC, and after administration of one and four cycles of FEC. Results: Thirty-six eligible patients were enrolled. The baseline characteristics of the two groups were well balanced. FACT-B scores at baseline and after four cycles of taxanes were 115/108 (DTX/nab-PTX) and 99/92, respectively. There were no significant differences between DTX and nab-PTX for FACT-B, FACT-B-Trial Outcome Index (FACT-B-TOI) and FACT-General. FACT-B and FACT-B TOI scores tended to decrease after one cycle and after four cycles of chemotherapy which did not recover to the baseline scores through the end of chemotherapy in each group. Conclusion: There were no significant safety differences between nab-PTX and DTX. HRQoL tended to decrease during taxane-based anticancer treatment, with no significant differences between the treatments. We suggest that the HRQoL questionnaire has limited ability to evaluate different chemotherapy schedules. Trial registration UMIN000009855. Nov 20, 2012 registered. PMID- 30288493 TI - Evaluation of Breast Cancer (BC) Awareness among Female University Students in Zarqa University, Jordan. AB - Objective: The purposes of this study were to assess the level of Breast Cancer (BC) awareness of Jordanian female university students, measure their attitudes toward BC treatment, and compare the level of awareness and attitudes of students in the science and humanities faculties. Materials and Methods: The current study was cross-sectional and conducted among female students in Zarqa University in Jordan. Stratified random sampling and simple random sampling were employed to select the colleges and the students, respectively. The sample size was 326 students. Data was collected and analyzed by self-administered questionnaire and SPSS version 23.0, respectively. Results: The number (proportion) of university students who had poor levels of awareness of BC, general knowledge about BC scale, knowledge about BC symptoms scale, and knowledge about risk factors of BC scale were was 270 (83%), 166 (51%), 182 (56%) and 292 (90%), respectively. Also, 92 (28%) students and 234 (72%) students had high and medium attitudes toward BC treatment, respectively. There were significant differences between the humanities and science faculties students' awareness about BC and their attitudes toward BC treatment (p<0.05). Also, the results revealed that the students' main information source about BC was mainly health-care professionals, followed by internet and television. Conclusion: The current status of awareness of BC among Jordanian female students and their attitudes toward BC treatment are insufficient. Therefore, university compulsory courses need to be modified to include BC topics and promote awareness about BC. PMID- 30288494 TI - The Effect on Quality of Life and Body Image of Mastectomy Among Breast Cancer Survivors. AB - Objective: The objective of the present study was to determine effect on quality of life (QoL) and body image level following mastectomy among breast cancer (BC) survivors. Materials and Methods: In this descriptive study was carried out between February 2015 and December 2016 with 57 women with modified radical mastectomy and who in stage II and stage III. Data were collected using the socio demographic and body cathexis scale, Functional Assessment of Cancer Therapy Breast (FACT-B) to determine QoL. The study was carried out in home environment in which women lived. Results: The average age of the women was 49.34 years (ranged 28-78 years). Most of the women had undergone mastectomy for more than 6 months.. Most of the women also received adjuvant chemotherapy and radiotherapy. The study showed that the mean FACT-B total score of the women was 68.47 (SD=22.44), and the body image score was 121.61(SD=21.96). According to the results of linear regression analysis, except for the social/family well-being of FACT-B, positive correlations were calculated among the other sub-dimensions of FACT-B and the FACT-B total score and the body image total score respectively (beta=0.822, p=0.000). In the multiple linear regression model, there was medium correlation between education and work status with QoL, no correlation between QoL and other features of women. There was important positive relationship between body image with time after mastectomy and chemotherapy and no correlation between body image and other features of women. Conclusion: The results of this study showed that the mastectomy has a negative impact on body image and QoL of women and there was a strong positive correlation between body image and QoL. PMID- 30288495 TI - The Impact of Subtype Distribution in Inflammatory Breast Cancer Outcome. AB - Objective: Inflammatory breast cancer (IBC) has an unfavourable prognosis despite the advances made in the treatment of breast cancer. Our study aimed to define immunohistochemistry-based surrogate subtype distribution to determine whether the breast cancer subtype accompanied survival outcome differences in IBC. Materials and Methods: Medical records of female breast cancer patients with non metastatic inflammatory breast cancer admitted to our clinic between March 2000 and December 2015 were retrospectively reviewed. Patient demographics, clinical and pathological feature of the primary tumour, adjuvant treatment options and survival data were analysed. Intrinsic breast cancer subtypes were defined according to ER, PR, HER-2 and ki-67 status. Results: We identified 129 non metastatic inflammatory breast cancer patients. Median follow-up was 73 months. 10 (7.7%) were luminal A-like, 67 (51.9%) were luminal B-like, 37 (28.6%) were HER-2 positive, and 15 (11.6%) were triple negative (TNBC) by immunohistochemistry. There were no statistically significant differences between subtypes in terms of histological type, grade, tumour size and lymph node status. Median disease-free survival was 47 months (95% confidence interval [CI] 29.2 82.6) and median overall survival was 75 months (95% CI 64.7-90.8). Triple negative breast cancer showed poorer outcome than other subgroups. Presence of TNBC disease was associated with poorer outcome compared to luminal A (HR: 0.19, 95% CI 0.04-0.92, p: 0.039), luminal B (HR: 0.34, 95% CI 0.15-0.74, p: 0.007) and HER-2 positive subgroups (HR: 0.40, 95% CI 0.17-0.94, p:0.037). Luminal A patients had a trend to have a better overall survival which did not reach to a statistical significant difference. Conclusion: Our study put forth that IBC have a poor prognosis irrespective of breast cancer surrogate subtype distribution. Luminal A, the most frequent subtype of breast cancer was the least common in our IBC patient group. TNBC had the worst outcome when compared to other breast cancer subtypes. PMID- 30288496 TI - The Significance of Extent of Extracapsular Extension in Patients with T1-2 and N1 Breast Cancer. AB - Objective: The prognostic importance of extracapsular extension (ECE) in breast cancer is not yet clear, especially in patients with pathological T1-2 and N1 (pT1-2N1) disease. We aimed to investigate whether the extent of ECE was an independent prognostic factor for survival outcomes in patients with pT1-2N1 breast cancer. Materials and Methods: A total number of 131 patients with pT1-2N1 breast cancer treated between 2009 and 2015 were retrospectively evaluated. A single pathologist re-analyzed the histologic examples of all cases. The extent of ECE was graded from 0 to 4. Results: There was a significant correlation between the number of lymph nodes involved and ECE grade (p=0.004). According to the univariate analysis, lymphovascular invasion (LVI) and ECE grade were the significant prognostic factors for overall survival (OS); age, number of metastatic lymph nodes, menopausal status, and ECE grade were the prognostic factors for disease-free survival (DFS). With a median follow-up of 46 months, grade 3-4 ECE seems to be notably associated with a shorter OS and DFS in multivariate analysis. The mean OS was 85 months for the patients with grade 0-2 ECE vs 75 months for the patients with grade 3-4 ECE (p=0.003). The mean DFS was 83 months for the patients with grade 0-3 ECE vs 68 months for the patients with grade 4 ECE (p=<0.0001). Conclusion: This research has shown that the extent of ECE is an important prognostic factor for survival in pT1-2N1 breast cancer patients and grade 3-4 ECE seems to be notably associated with a shorter OS and DFS. PMID- 30288497 TI - Impact of The Method of Diagnosis on The Stage of Breast Carcinoma. AB - Objective: Screening mammography is recommended to women at a certain age to achieve an early diagnosis. The purpose of this study is to find out how breast carcinoma was diagnosed and the impact of the method of diagnosis on the stage of the tumor. Materials and Methods: In this study, 903 operated breast cancer patients, between 2010-2016, in a large volume Marmara University Istanbul Pendik Education and Research Hospital were analyzed retrospectively. Patients presenting with clinical symptoms and those diagnosed with screening were investigated separately. The percentage of the patients diagnosed with symptoms and the impact of the method of diagnosis on the stage of the tumor was the primary outcome of the study. Results: 738 patients fulfilling inclusion criteria with complete clinical records were analyzed. 126 patients (17%) were in the age range of 19-39 years, while 32% (236 patients) were 40-50 and 51% (376 patients) were older than 50 years.485 patients (65.7%) were diagnosed with a mass in the breast, while 241 (32.6%) patients were diagnosed with screening with mammography. Twelve patients (1.7%) presented with nipple discharge. Median tumor sizes measured in the resected specimen were 22 mm, 21 mm, and 21 mm in patients diagnosed with a mass, screening, and nipple discharge respectively. The difference among the groups were not significant (p=0.460).Axillary lymph nodes were positive in 210 (43.3%) of patients presenting with a mass in the breast while 85 patients (35.3%) diagnosed with screening had metastatic lymph nodes in the axilla. Three patients presenting with nipple discharge had positive axillary lymph nodes (p=0.137). Conclusion: This study demonstrated that breast cancer screening programs in Turkey needs improvement and at the same time shows that screening with mammography after 40 years of age should be done annually despite Ministry of Health recommendations. PMID- 30288498 TI - Bilateral Inflammatory Pseudotumour of the Breast: A Case Report and Review of the Literature. AB - Inflammatory tumour (IPT) consists of spindle cells, mature plasma cells, histiocytes, lymphocytes and eosinophils. Most frequently presenting in the respiratory tract it can also affect other sites such as breast. This case was a 73-year old woman presenting with a left breast lump, clinically indeterminate (P3), proven on biopsy to be IPT. Seven years later she returned with bilateral breast lumps and underwent triple assessment followed by wide excisions which confirmed the diagnosis of IPTs. Because it can be difficult to differentiate IPT from a low-grade spindle cell metaplastic breast carcinoma (SpCMBC) wide excision to achieve clear margins should be achieved to exclude malignancy.

AB - Dermatofibrosarcoma protuberans is a rare form of soft tissue sarcoma that tends to invade and recur locally. The most common site of this disease is head, neck and extremities; however, the involvement of the breast has been reported. We present a case with a dermatofibrosarcoma of the breast that is composed of low grade spindle cells which are positive for CD43. She was treated by wide surgical excision followed by adjuvant external beam irradiation at a dose of 60 Gray. After a follow-up of 24 months, no local-regional or distant recurrence was detected.

AB - Trastuzumab, a humanized monoclonal antibody directed against human epidermal growth factor receptor 2 (HER2), remains the standard of care as part of adjuvant therapy for patients diagnosed with HER2-positive breast cancers. Despite high therapeutic efficacy, trastuzumab-based regimens can cause serious cardiotoxic side effects. Effective mitigation of cardiotoxic risk relies on thorough understanding of molecular mechanisms of cardiotoxicity induced by trastuzumab. Among the probable mechanisms responsible for trastuzumab-mediated cardiotoxicity, generation of free radicals causing oxidative stress has garnered notable attention in recent years. More recently, role of autophagy in trastuzumab-induced cardiomyopathy was explored. Trastuzumab-mediated HER2 signaling dysregulation activated Erk/mTOR signaling cascade resulting in autophagy inhibition. Consequently, autophagy impairment leads to massive accumulation of damaged mitochondria and free radicals causing oxidative stress and toxicity in cardiomyocytes. This review will discuss recent advances in understanding the mechanism of oxidative stress and highlight the role of autophagy in trastuzumab-mediated cardiac dysfunctions.

AB - : The development and validation studies of new multisensory biomarkers and sensor-triggered interventions requires collecting raw sensor data with associated labels in the natural field environment. Unlike platforms for traditional mHealth apps, a software platform for such studies needs to not only support high-rate data ingestion, but also share raw high-rate sensor data with researchers, while supporting high-rate sense-analyze-act functionality in real time. We present mCerebrum, a realization of such a platform, which supports high rate data collections from multiple sensors with realtime assessment of data quality. A scalable storage architecture (with near optimal performance) ensures quick response despite rapidly growing data volume. Micro-batching and efficient sharing of data among multiple source and sink apps allows reuse of computations to enable real-time computation of multiple biomarkers without saturating the CPU or memory. Finally, it has a reconfigurable scheduler which manages all prompts to participants that is burden- and context-aware. With a modular design currently spanning 23+ apps, mCerebrum provides a comprehensive ecosystem of system services and utility apps. The design of mCerebrum has evolved during its concurrent use in scientific field studies at ten sites spanning 106,806 person days. Evaluations show that compared with other platforms, mCerebrum's architecture and design choices support 1.5 times higher data rates and 4.3 times higher storage throughput, while causing 8.4 times lower CPU usage.

PMID- 30288502 TI - Using structural and functional brain imaging to uncover how the brain adapts to blindness. AB - Advances in neuroimaging technology have been instrumental in uncovering the dramatic neurological changes that result from blindness, as well as revealing the inner workings of the human brain. Specifically, modern imaging techniques enable us to examine how the brain adapts and "re-wires" itself as a result of changes in behavior, the environment, injury, or disease; a process referred to as neuroplasticity. Following an overview of commonly employed neuroimaging techniques, we discuss structural and functional neuroplastic brain changes associated with profound visual deprivation. In particular, we highlight how associated structural changes often occur within areas that process intact senses (such as hearing, touch, and smell) while functional changes tend to implicate areas of the brain normally ascribed to the processing of visual information. Evidence will primarily focus on profound blindness due to ocular cause, but related work in cerebral/cortical visual impairment (CVI) will also be discussed. The potential importance of these findings within the context of education and rehabilitation is proposed. PMID- 30288507 TI - Distinct roles of SNARE-mimicking lipopeptides during initial steps of membrane fusion. AB - A model system for membrane fusion, inspired by SNARE proteins and based on two complementary lipopeptides CPnE4 and CPnK4, has been recently developed. It consists of cholesterol (C), a poly(ethylene glycol) linker (Pn) and either a cationic peptide K4 (KIAALKE)4 or an anionic peptide E4 (EIAALEK)4. In this paper, fluorescence spectroscopy is used to decipher distinct but complementary roles of these lipopeptides during early stages of membrane fusion. Molecular evidence is provided that different distances of E4 in CPnE4 and K4 in CPnK4 from the bilayer represent an important mechanism, which enables fusion. Whereas E4 is exposed to the bulk and solely promotes membrane binding of CPnK4, K4 loops back to the lipid-water interface where it fulfills two distinct roles: it initiates bilayer contact by binding to CPnE4 containing bilayers; and it initiates fusion by modulating the bilayer properties. The interaction between CPnE4 and CPnK4 is severely down-regulated by binding of K4 to the bilayer and possible only if the lipopeptides approach each other as constituents of different bilayers. When the complementary lipopeptides are localized in the same bilayer, hetero-coiling is disabled. These data provide crucial insights as to how fusion is initiated and highlight the importance of both peptides in this process.

AB - Homonuclear correlations are key to structural studies using solid-state NMR. In this contribution, using 14N overtone transition (OT) as a selective excitation approach, we propose a proton-detected one-dimensional (1D) 14NOT/14NOT/1H correlation solid-state NMR method mediated through 1H/1H mixing at fast magic angle spinning to achieve NH/NH proximities in naturally abundant samples. The proposed method is time efficient by a factor of ~7.5 in comparison to the existing fundamental 14N frequency-based three-dimensional (3D) 14N/14N/1H correlation method.

PMID- 30288511 TI - Factors affecting microbial and physico-chemical pollutants in stormwater in a typical Chinese urban catchment. AB - An understanding of microbial pollution characteristics is needed for stormwater reuse and development of microorganism simulations in urban stormwater. This study investigated the discharge characteristics of faecal indicator bacteria (faecal coliforms) in urban runoff by field sampling both the underlying surfaces and the stormwater pipe outlet. Faecal coliform contamination in urban runoff was found to be frequent, and the highest instantaneous concentration reached 2.42 * 106 MPN/100 ml. Faecal coliforms did not show a consistent first flush effect amongst the different surfaces sampled, and this was exacerbated under rainfall events with high intensity. PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation) and GAIA (Geometrical Analysis for Interactive Aid) analyses were further applied to explore the ranking of pollutants, the relationship among the pollutants, and the factors affecting the contamination in cases of multiple underlying surfaces, multiple pollutants and rainfall events. For the pollutants of suspended solids (SS), total phosphorus (TP) and chemical oxygen demand (COD), the road sample contamination was significantly higher than on the roof surfaces. No such trend in ranking of faecal coliforms was observed. Rainfall depth and intensity were found to have a significant influence on stormwater contamination by physico-chemical pollutants, while having a somewhat smaller influence on faecal coliform contamination. Faecal coliform contamination is closely associated with the index related to the antecedent dry period. The average temperature and average relative humidity also showed a positive relationship with faecal coliform contamination. The effects of antecedent dry period duration on contamination of physico-chemical pollutants and faecal coliform are completely opposite. Antecedent dry period duration was positively related to the contamination of physico-chemical pollutants, but negatively related to faecal coliform contamination. Therefore, three variables, i.e., antecedent dry period duration, average temperature and average relative humidity, might be used to model the survival/die-off of faecal coliform during the antecedent dry period.

PMID- 30288513 TI - Machine learning and artificial neural network prediction of interfacial thermal resistance between graphene and hexagonal boron nitride. AB - High-performance thermal interface materials (TIMs) have attracted persistent attention for the design and development of miniaturized nanoelectronic devices; however, a large number of potential new materials exist to form these heterostructures and the explorations of their thermal properties are time consuming and expensive. In this work, we train several supervised machine learning (ML) and artificial neural network (ANN) models to predict the interfacial thermal resistance (R) between graphene and hexagonal boron-nitride (hBN) with only the knowledge of the system temperature, coupling strength between two layers, and in-plane tensile strains. The training data were obtained by high-throughput computations (HTCs) of R using classical molecular dynamics (MD) simulations. Four different ML models, i.e., linear regression, polynomial regression, decision tree and random forest, are explored. A pair of one dense layer ANNs and another pair of two dense layer deep neural networks (DNNs) are also investigated. It is reported that the DNN models provide better R prediction results compared to the ML models. The thermal property predictions using HTC and ML/ANN models are applicable to a wide range of materials and open up new perspectives in the explorations of TIMs. PMID- 30288514 TI - Detecting weak signals from interfaces by high accuracy phase-resolved SFG spectroscopy. AB - Much work over the last 25 years has demonstrated that the interface-specific, all-optical technique, vibrational sum frequency generation (v-SFG) spectroscopy, is often uniquely capable of characterizing the structure and dynamics of interfacial species. The desired information in such a measurement is the complex second order susceptibility which gives rise to the nonlinear response from interfacial molecules. The ability to detect molecular species yielding only small contributions to the susceptibility is meanwhile limited by the precision by which the spectral phase and amplitude can be determined. In this study we describe a new spectrometer design that offers unprecedented phase and amplitude accuracy for extended studies that involve multiple spectral acquisitions while modifying sample properties. The key to this significant improvement to the sensitivity of the technique is the combination of a full collinear beam geometry with broadband spectral sampling and the ability to simultaneously measure the complex sample and reference spectrum. We show that using this technique uncertainties in the reference phase and amplitude can be greatly reduced. Furthermore, we show that using balanced detection, the signal to noise ratio can be increased by one order of magnitude. The capabilities of the spectrometer are demonstrated by the isolation of a small isotropic surface signal from the bulk dominated nonlinear optical response of z-cut quartz. The achieved precision of our spectrometer enables measurements not currently feasible in v-SFG spectroscopy. PMID- 30288515 TI - Influence of compatible solute ectoine on distinct DNA structures: thermodynamic insights into molecular binding mechanisms and destabilization effects. AB - In nature, the cellular environment of DNA includes not only water and ions, but also other components and co-solutes, which can exert both stabilizing and destabilizing effects on particular oligonucleotide conformations. Among them, ectoine, known as an important osmoprotectant organic co-solute in a broad range of pharmaceutical products, turns out to be of particular relevance. In this article, we study the influence of ectoine on a short single-stranded DNA fragment and on double-stranded helical B-DNA in aqueous solution by means of atomistic molecular dynamics (MD) simulations in combination with molecular theories of solution. Our results demonstrate a conformation-dependent binding behavior of ectoine, which favors the unfolded state of DNA by a combination of electrostatic and dispersion interactions. In conjunction with the Kirkwood-Buff theory, we introduce a simple framework to compute the influence of ectoine on the DNA melting temperature. Our findings reveal a significant linear decrease of the melting temperature with increasing ectoine concentration, which is found to be in qualitative agreement with results from denaturation experiments. The outcomes of our computer simulations provide a detailed mechanistic rationale for the surprising destabilizing influence of ectoine on distinct DNA structures. PMID- 30288516 TI - A biodegradable fluorescent nanohybrid for photo-driven tumor diagnosis and tumor growth inhibition. AB - Specific targeting and phototriggered therapy in mouse model have recently emerged as the starting point of cancer theragnosis. Herein, we report a bioresponsive and degradable nanohybrid, a liposomal nanohybrid decorated with red emissive carbon dots, for localized tumor imaging and light-mediated tumor growth inhibition. Unsaturated carbon dots (C-dots) anchored to liposomes convert near-infrared (NIR) light into heat and also produce reactive oxygen species (ROS), demonstrating the capability of phototriggered cancer cell death and tumor regression. The photothermal and oxidative damage of breast tumor by the nonmetallic nanohybrid has also been demonstrated. Designed nanoparticles show excellent aqueous dispersibility, biocompatibility, light irradiated enhanced cellular uptake, release of reactive oxygen species, prolonged and specific tumor binding ability and good photothermal response (62 degrees C in 5 minutes). Safe and localized irradiation of 808 nm light demonstrates significant tumor growth inhibition and bioresponsive degradation of the fluorescent nanohybrid without affecting the surrounding healthy tissues. PMID- 30288517 TI - A G-triplex based molecular beacon for label-free fluorescence "turn-on" detection of bleomycin. AB - Since bleomycins (BLMs) play a prominent role in the clinical treatment of various cancers, the development of convenient and sensitive detection assays for BLM is of great significance in cancer therapy and related biological mechanism research. Here, taking advantage of the easily controllable and excitation of the G-triplex DNA structure, we reported a facile, label-free G-triplex based functional molecular beacon (G3MB) sensing system for fluorescence "turn-on" detection of BLM based on BLM-Fe(ii) mediated DNA strand scission. In the presence of BLM, the stable hairpin structure of G3MB undergoes an irreversible cleavage in the loop region that contains a 5'-GT-3' recognition site for BLM. The released G-tract DNA fragment self-assembles into a G-triplex-ThT complex showing a strong fluorescence. Owing to the effective locking of G-tracts in the stem of the G3MB and the specific DNA strand scission by BLM which is like a key for the release of G-tracts, the assay shows high sensitivity and selectivity with a detection limit of 0.2 nM. In addition, satisfactory results were obtained for the detection of BLM in human serum samples. Critically, the convenient "mix and-detect" protocol, fast response and no need for modifying DNA offered a potential application of the proposed strategy for BLM assay in biomedical and clinical studies.

AB - We describe a potential molecular mechanism explaining how DNA methylation contributes to biological regulation.

We observe that, depending on the sequence, DNA methylation hinders overwinding or underwinding molecular transitions. PMID- 30288519 TI - SERS-based quantification of albuminuria in the normal-to-mildly increased range. AB - The lack of an accurate point-of-care detection system for microalbuminuria represents an important unmet medical need that contributes to the morbidity and mortality of patients with kidney diseases. In this proof-of-concept study, we used SERS spectroscopy to detect urinary albumin concentrations in the normal-to mildly increased albuminuria range, a strategy that could be useful for the early diagnosis of renal impairment due to uncontrolled hypertension, cardiovascular disease or diabetes. We analyzed 27 urine samples by SERS, using iodide-modified silver nanoparticles and we could discriminate between groups with high and low albumin concentrations with an overall accuracy of 89%, 93% and 89%, using principal component analysis-linear discriminant analysis and cut-off values of 3, 6 and 10 MUg mL-1 for urinary albumin concentrations, respectively. We achieved a detection limit of 3 MUg mL-1 for human serum albumin based on the 1002 cm-1 SERS band, attributed to the ring breathing vibration of phenylalanine. Our detection limit is similar to that of the immunoturbidimetric assays and around one order of magnitude below the detection limit of urinary dipsticks used to detect microalbuminuria. We used principal least squares regression for building a spectral model for quantifying albumin. Using an independent prediction set, the R2 and root mean squared error of prediction between predicted and reference values of human serum albumin concentrations were 0.982 and 2.82, respectively. Here, we show that direct SERS spectroscopy has the sensitivity required for detecting clinically relevant concentrations of urinary albumin, a strategy that could be used in the future for the point-of-care screening of microalbuminuria. PMID- 30288520 TI - Effect of surface coverage and chemistry on self-assembly of monolayer protected gold nanoparticles: a molecular dynamics simulation study. AB - Gold nanoparticles (AuNP) are being used in a variety of applications ranging from drug delivery systems to nano-coolants. The structure and surface properties of AuNP can be manipulated using coatings of thiols, carrying different charges. Different densities of surface coverage can result in the formation of different structures. A molecular basis to quantify the interactions between AuNP covered with different densities (20, 60 and 100%) of surface coverage and various thiol chains (neutral, cationic and anionic) is obtained using potential of mean force (PMF) calculations. Further self-assembly simulations were performed to study the formation of aggregates/dispersed solutions with different densities of surface coverage (20, 40, 60, 80 and 100%). It is found that neutral coatings of all surface coverage densities studied, and charged coatings (anionic and cationic) of less than 60% surface coverage density result in the formation of aggregates. The aggregation and dispersion of AuNPs is explained in terms of an interplay between van der Waals and electrostatic forces. The results obtained are in good agreement with the data available in the literature and suggest that aggregation behaviour can be controlled by modifying the surface coverage and chemistry.

AB - A highly enantioselective fluorination of indanone-2-carboxylates catalyzed by a polystyrene-supported diphenylamine-linked bis(oxazoline) (PS-box)-Cu(OTf)2 complex has been developed in a continuous flow system. The supported complex exhibited extremely efficient catalytic performance with high activity, affording the corresponding products in excellent yields (up to 99% yield) with excellent enantioselectivities (up to 99% ee) and more than 4000 turnover number (TON).

AB - A palladium(ii)-mediated rapid 11C-cyanation of (hetero)arylborons with [11C]NH4CN/NH3 has been developed using bench-stable and readily available reagents. The method showed excellent functional-group tolerance, and allowed the highly efficient synthesis of a wide range of [11C]cyanoarenes, including PET tracers for aromatase imaging. A mechanistic study of the 11C-cyanation suggests the instantaneous formation of a mono[11C]cyanopalladium(ii) complex that reacts smoothly with arylborons.

AB - Heterostructures enable the control of transport and recombination of charge carriers, which are either injected through electrodes, or created by light illumination. Instead of full 2D-material-heterostructures in device applications, using hybrid heterostructures consisting of 2D and 3D materials is an alternative approach to take advantage of the unique physical properties of 2D materials. In addition, 3D dielectric nanostructures exhibit useful optical properties such as broadband omnidirectional antireflection effects and strongly concentrated light near the surface. In this work, the optical properties of 2D MoS2 monolayers conformally coated on 3D Si-based nanocone (NC) arrays are investigated. Numerical calculations show that the absorption in MoS2 monolayers on SiO2 NC is significantly enhanced, compared with that for MoS2 monolayers on Si NC. The weak light confinement in low refractive index SiO2 NC leads to greater absorption in the MoS2 monolayers. The measured photoluminescence and Raman intensities of the MoS2 monolayers on SiO2 NC are much greater than those on Si NC, which supports the calculation results. This work demonstrates that 2D MoS2-3D Si nano-heterostructures are promising candidates for use in high performance integrated optoelectronic device applications. PMID- 30288524 TI - Poly(ethylene glycol)-poly-l-glutamate complexed with polyethyleneimine polyglycine for highly efficient gene delivery in vitro and in vivo. AB - To improve gene transfection efficiency in vitro and in vivo, we first grafted polyglycine (PGly) onto branched polyethyleneimine (PEI) (molecular weight MW 25 kDa) to obtain a novel gene vector PGly-PEI (PPG), before complexing it with poly(ethylene glycol)-poly-l-glutamate (PEG-PLG) for adjusting the charge density of PEI. We named the resulting nano-polyplex PG/PPG. The PPGs demonstrated improved gene transfection efficiency after grafting with polyglycine, and the efficiency could be further increased with the introduction of PEG-PLG. The PG/PPG exhibited not only excellent DNA and siRNA transfection capacity in various cell lines including HeLa, CHO, HepG2, MCF7 and Huh7, but also reduced cytotoxicity compared with PEI. Besides, PG/PPG induced a higher degree of cell apoptosis when mixed genes of pKH3-rev-casp-3 plasmid and siBcl2 were used rather than either of them. Furthermore, PG/PPG was highly resistant to serum, which led to enhanced in vivo red fluorescent protein (RFP) expression in HeLa tumors. These results suggested that PG/PPG is a promising gene carrier for highly efficient gene delivery.

AB - Constructing heterostructures is an effective strategy for designing efficient electrocatalysts. MoS2 is a star catalyst for hydrogen evolution reaction (HER) in acidic media; however, the alkaline HER activity is deficient due to the sluggish water dissociation process. Herein, Ni(OH)2/MoS2 heterostructures with Ni(OH)2 nanoclusters epitaxially decorated on the surface of MoS2 are synthesized towards the alkaline HER. As compared with MoS2, the epitaxial Ni(OH)2/MoS2 heterostructures show significantly enhanced HER activity in 1 M KOH, and the overpotential is decreased by nearly 150 mV to reach a current density of 10 mA cm-2. The substantial increase in turnover frequency (TOF) demonstrates that the intrinsic activity is greatly improved after the incorporation of Ni(OH)2 nanoclusters. The presence of Ni(OH)2 nanoclusters would provide additional water dissociation sites while MoS2 is ready for the adsorption and combination of the generated H*, and this so-called synergistic effect eventually induces significantly enhanced alkaline HER kinetics. Besides, the electron transfer from Ni(OH)2 to MoS2 increases the proton affinity of MoS2. The present results describe an interesting case of an atomic-scale electrochemically inert material promoted HER process, and would open a new avenue into designing efficient hetero nanostructures towards electrocatalytic applications.

AB - We synthesized and characterized two novel sterol-anchored polyethylene glycols (PEG) as potential alternatives to conventional phosphatidylethanolamine-PEGs. Liposomes containing the dicholesterol anchored PEG at 5 mole percent exhibit canonical PEGgylated-liposome behaviors including retention of encapsulated small molecules, low serum protein adsorption, and reduced cellular uptake yet they do not exhibit long circulation. PMID- 30288532 TI - Creep dynamics of athermal amorphous materials: a mesoscopic approach. AB - Yield stress fluids display complex dynamics, in particular when driven into the transient regime between the solid and the flowing state. Inspired by creep experiments on dense amorphous materials, we implement mesoscale elasto-plastic descriptions to analyze such transient dynamics in athermal systems. Both our mean-field and space-dependent approaches consistently reproduce the typical experimental strain rate responses to different applied steps in stress. Moreover, they allow us to understand basic processes involved in the strain rate slowing down (creep) and the strain rate acceleration (fluidization) phases. The fluidization time increases in a power-law fashion as the applied external stress approaches a static yield stress. This stress value is related to the stress over shoot in shear start-up experiments, and it is known to depend on sample preparation and age. By calculating correlations of the accumulated plasticity in the spatially resolved model, we reveal different modes of cooperative motion during the creep dynamics.

AB - An efficient and highly productive rhodium-catalyzed method for the synthesis of nitriles employing aldehydes or ketones, methyl cyanoacetate, water and carbon monoxide as starting materials has been developed.

AB - Polymer hydrogels formed by rapid thiol-ene coupling of macromolecular gel formers can offer access to versatile new matrices. This paper describes the efficient synthesis of cysteamine vinyl sulfone (CVS) trifluoroacetate, and its incorporation into poly(methyl vinyl ether-alt-maleic anhydride) (PMMAn) to form a series of CVS-functionalized poly(methyl vinyl ether-alt-maleic acid) polymers (PMM-CVSx) containing 10 to 30 mol% pendant vinyl sulfone groups. Aqueous mixtures of these PMM-CVS and a dithiol crosslinker, alpha,omega-dithio polyethyleneglycol (HS-PEG-SH, Mn = 1 kDa), gelled through crosslinking by Michael addition within seconds to minutes, depending on pH, degree of functionalization, and polymer loading. Gelation efficiency, Young's modulus, equilibrium swelling and hydrolytic stability are described, and step-wise hydrogel post-functionalization with a small molecule thiol, cysteamine, was demonstrated. Cytocompatibility of these crosslinked hydrogels towards entrapped 3T3 fibroblasts was confirmed using a live/dead fluorescence assay. PMID- 30288535 TI - Influence of the donor unit on the rectification ratio in tunnel junctions based on donor-acceptor SAMs using PTM units as acceptors. AB - Dyads formed by an electron donor unit (D) covalently linked to an electron acceptor (A) by an organic bridge are promising materials as molecular rectifiers. Very recently, we have reported the charge transport measurements across self-assembled monolayers (SAMs) of two D-A systems consisting of the ferrocene (Fc) electron-donor linked to a polychlorotriphenylmethane (PTM) electron-acceptor in its non-radical (SAM 1) and radical (SAM 2) forms. Interestingly, we observed that the non-radical SAM 1 showed rectification behavior of 2 orders of magnitude higher than its radical analogue dyad 2. In order to study the influence of the donor unit on the transport properties, we report herein the synthesis and characterization of two new D-A SAMs in which the electron-donor Fc unit is replaced by a tetrathiafulvalene (TTF) moiety linked to the PTM unit in its non-radical (SAM 3) and radical (SAM 4) forms. The observed decrease in the rectification ratio and increased current density for TTF-PTM based SAMs 3 and 4 in comparison to Fc-PTM based SAMs 1 and 2 are explained, supported by theoretical calculations, by significant changes in the electronic and supramolecular structures. PMID- 30288536 TI - Polyamidoxime chain length drives emergent metal-binding phenomena. AB - Emergence is complex behavior arising from the interactions of many simple constituents that do not display such behavior independently. Polyamidoxime (PAO) uranium adsorbents show such phenomena, as recent works articulate that the polymer binds uranium differently than the monomeric constituents. In order to investigate the origins of this emergent uranium-binding behavior, we synthesized a series of amidoxime polymers with low polydispersity and small molecules with lengths ranging from 1 to 125 repeat units. Following immersion in a uranyl containing solution, the local, intermediate, and macroscopic structures were investigated by X-ray absorption fine structure (XAFS) spectroscopy, small angle neutron scattering (SANS), and dynamic light scattering (DLS). Fits of the extended XAFS (EXAFS) region revealed a progressive change in uranium coordination environment as a function of polymer molecular weight, identifying chain length as a driving force in emergent metal binding and resolving the controversy over how amidoxime adsorbents bind uranium.

AB - A variety of unsymmetrical 1,3-diynes can easily be accessed in good yields under catalyst- and transition metal-free conditions by reacting terminal alkynes with hypervalent iodine-based electrophilic alkyne-transfer reagents. PMID- 30288538 TI - UPS and UV spectroscopies combined to position the energy levels of TiO2 anatase and rutile nanopowders. AB - An accurate experimental determination of electronic structures in semi-conductor nanopowders is a challenging task. We propose here to combine UPS and UV-Vis spectroscopies in order to get the full description of the electronic band alignment of powder samples, TiO2 rutile and anatase. For UPS measurements, two preparation methods, namely the dropping method and electrophoretic deposition, were used to prepare layers of titania powders on a conducting substrate, ITO or Ag. Both methods lead to comparable results, with a quantitative description of the energy levels from the valence band. Combining these results with the UV-Vis spectra of the same powders enables the determination of the absolute position of the valence band maximum and the conduction band minimum. Combined UPS-UV-Vis spectroscopy provides a better insight into the properties of a powdered material which can differ from single crystal model systems. It can also be used to predict the electronic transfer in mixed phase systems during photocatalytic processes.

AB - Under catalyst-free conditions, an efficient method for the synthesis of 2 aminopyridine derivatives through the nucleophilic substitution and hydrolysis of 2-fluoropyridine and acetamidine hydrochloride has been developed. This amination uses inexpensive acetamidine hydrochloride as the ammonia source and has the advantages of a high yield, high chemoselectivity and wide substrate adaptability. The results suggest that other N-heterocycles containing fluorine substituents can also complete the reaction via these reaction conditions and yield the target products. PMID- 30288540 TI - Electric-field control of non-volatile 180 degrees switching of the unidirectional anisotropy field in a multiferroic heterostructure. AB - We investigate the room-temperature, electric-field-mediated, non-volatile 180 degrees switching of the unidirectional anisotropy field in an IrMn/CoFeB/Ta/Pb(Mg1/3Nb2/3)O3-PbTiO3 heterostructure. The variation in exchange bias under different electric fields appears clearly in the magnetic hysteresis loops. The remnant magnetization as a function of electric field, as determined by static magnetic measurements, exhibits a non-volatile behavior, which is consistent with the results of the ferromagnetic resonance field as a function of electric field. Moreover, the measured ferromagnetic resonance shows that the uniaxial magnetic anisotropy field is non-volatile and the unidirectional anisotropy field undergoes 180 degrees switching that can be acquired and separated distinctly. This result is attributed to the piezo-strain effect. The electric-field-mediated non-volatile 180 degrees switching of the unidirectional anisotropy field paves the way for sensors and other spintronic devices. PMID- 30288541 TI - A DFT analysis of the ground and charge-transfer excited states of Sc3N@Ih-C80 fullerene coupled with metal-free and zinc-phthalocyanine. AB - Endohedral metallofullerenes and phthalocyanine derivatives are recognized as excellent active materials in organic photovoltaics (OPVs). The tri-metallic nitride endohedral C80 fullerenes have greater absorption coefficients in the visible region and electron-accepting abilities similar to C60, which can allow for higher efficiencies in OPV devices. In this work, we have investigated the ground and charge transfer excited states of two co-facial donor-acceptor (D-A) molecular conjugates formed by the non-covalent coupling of trimetallic nitride endohedral fullerene (Sc3N@Ih-C80) with metal-free (H2Pc) and zinc-phthalocyanine (ZnPc) chromophores using DFT calculations. The charge transfer (CT) excitation energies are calculated using the perturbative delta-SCF method that enforces orthogonality between the ground and excited states. The binding energies calculated using the PBE and DFT-D3 methods indicate that the dispersion effects play an important role in the stabilization of these complexes. The ground state dipole moment of the Sc3N@C80-H2Pc dyad is much larger than that of Sc3N@C80 ZnPc, but this is reversed in the excited state where the dipole moment of Sc3N@C80-ZnPc increases significantly. The lowest few excitation energies in the gas phase for the two complexes are very close, in the range of 1.51-2.66 eV for Sc3N@C80-ZnPc and 1.51-2.71 eV for the Sc3N@C80-H2Pc complex. However, the lower ionization potential and lower exciton binding energy make the Sc3N@C80-ZnPc dyad a better candidate for OPVs as compared to the Sc3N@C80-H2Pc dyad.

AB - The present review gives an overview over non-toxic cyanation agents and cyanide sources used in the synthesis of structurally diverse products containing the nitrile function.

AB - The catalytic redox activity of Cu(ii) bound to the motif NH2-Xxx-Zzz-His (ATCUN) with ascorbate and H2O2/O2 is very low and can be stopped via Cu(i)-chelation.

PMID- 30288544 TI - Genetic and Genome Analyses Reveal Genetically Distinct Populations of the Bee Pathogen Nosema ceranae from Thailand. AB - The recent global decline in Western honeybee (Apis mellifera) populations is of great concern for pollination and honey production worldwide. Declining honeybee populations are frequently infected by the microsporidian pathogen Nosema ceranae. This species was originally described in the Asiatic honeybee (Apis cerana), and its identification in global A. mellifera hives could result from a recent host transfer. Recent genome studies have found that global populations of this parasite are polyploid and that humans may have fueled their global expansion. To better understand N. ceranae biology, we investigated its genetic diversity within part of their native range (Thailand) and among different hosts (A. mellifera, A. cerana) using both PCR and genome-based methods. We find that Thai N. ceranae populations share many SNPs with other global populations and appear to be clonal. However, in stark contrast with previous studies, we found that these populations also carry many SNPs not found elsewhere, indicating that these populations have evolved in their current geographic location for some time. Our genome analyses also indicate the potential presence of diploidy within Thai populations of N. ceranae. PMID- 30288545 TI - Fungal, Bacterial, and Archaeal Diversity in Soils Beneath Native and Introduced Plants in Fiji, South Pacific. AB - The Fiji Islands is an archipelago of more than 330 islands located in the tropics of the South Pacific Ocean. Microbial diversity and biogeography in this region is still not understood. Here, we present the first molecular characterization of fungal, bacterial, and archaeal communities in soils from different habitats within the largest Fijian island, Viti Levu. Soil samples were collected from under native vegetation in maritime-, forest-, stream-, grassland , and casuarina-dominated habitats, as well as from under the introduced agricultural crops sugarcane, cassava, pine, and mahogany. Soil microbial diversity was analyzed through MiSeq amplicon sequencing of 16S (for prokaryotes), ITS, LSU ribosomal DNA (for fungi). Prokaryotic communities were dominated by Proteobacteria (~ 25%), Acidobacteria (~ 19%), and Actinobacteria (~ 17%), and there were no indicator species associated with particular habitats. ITS and LSU were congruent in beta-diversity patterns of fungi, and fungal communities were dominated by Ascomycota (~ 57-64%), followed by Basidiomycota (~ 20-23%) and Mucoromycota (~ 10%) according to ITS, or Chytridiomycota (~ 9%) according to LSU. Indicator species analysis of fungi found statistical associations of Cenococcum, Wilcoxina, and Rhizopogon to Pinus caribaea. We hypothesize these obligate biotrophic fungi were co-introduced with their host plant. Entoloma was statistically associated with grassland soils, and Fusarium and Lecythophora with soils under cassava. Observed richness varied from 65 (casuarina) to 404 OTUs (cassava) for fungi according to ITS region, and from 1268 (pine) to 2931 OTUs (cassava) for bacteria and archaea. A major finding of this research is that nearly 25% of the fungal OTUs are poorly classified, indicative of novel biodiversity in this region. This preliminary survey provides important baseline data on fungal, bacterial, and archaeal diversity and biogeography in the Fiji Islands. PMID- 30288548 TI - Predatory journals: a major threat in orthopaedic research. AB - Predatory publishing is a major threat to contemporary publishing, as it offers 'to unaware scientist's', a quick open-access publication against fees without peer-review procedures.. Lack of peer-review leads to unethical practices, as plagiarism, publication of unscientific falsified data, and even unsafe clinical practices. As these journals threaten the credibility of academic publishing, significant work has been done from many scientific teams, in the last years, in establishing discriminating criteria between predatory and legitimate publishing. In the present review, we include mechanisms used by predatory editors to convince eager researchers to submit to their journals. We also provide useful links giving information about potential predatory journals and publishers, as well as scholarly writing. Joining the efforts of different scientific disciplines which compiled "green" lists with journals in their field, we conducted a "green" list with genuine orthopaedic research journals based on the directory of open-access journals (DOAJ) and Thomson Reuters journal citation reports. Ninety-six legitimate orthopaedic journals were identified based on the Thomson Reuters journal citation reports. One hundred thirty hits were found on the DOAJ site using the keywords "orthopaedics, orthopedics, sports medicine, musculoskeletal, trauma, traumatology, osteoarthritis, osteoporosis, cartilage, bone, hand, shoulder, knee, hip, foot, wound." Twenty-one journals on the DOAJ site occurred overlapping with keywords. Researchers and clinicians in the field of orthopaedics are advised to use all available tools in order to recognize predatory practices and avoid publishing in predatory journals. PMID- 30288546 TI - Trichostatin A, a histone deacetylase inhibitor, induces synergistic cytotoxicity with chemotherapy via suppression of Raf/MEK/ERK pathway in urothelial carcinoma. AB - In this study, we aimed to investigate the antitumor effects of trichostatin A (TSA), an antifungal antibiotic that inhibits histone deacetylase (HDAC) family of enzymes, alone or in combination with anyone of the three chemotherapeutic agents (cisplatin, gemcitabine, and doxorubicin) for the treatment of human urothelial carcinoma (UC). Two high-grade human UC cell lines (T24 and NTUB1) were used. Cytotoxicity and apoptosis were assessed by MTT assay and flow cytometry, respectively. The expression of phospho-c-Raf, phospho-MEK1/2, and phospho-ERK1/2 was measured by western blotting. ERK siRNA knockdown and the specific MEK inhibitor U0126 were used to examine the role of Raf/MEK/ERK signaling pathway in combined cytotoxicity of TSA and chemotherapy. TSA co treatment with any one of the three chemotherapeutic agents induced synergistic cytotoxicity (combination index < 1) and concomitantly suppressed chemotherapeutic drug-induced activation of Raf-MEK-ERK pathway. Combination of ERK siRNA knockdown and treatment with the specific MEK inhibitor (U0126) enhanced the cytotoxic effects of the chemotherapy on UC cells. These observations were confirmed in a xenograft nude mouse model. Moreover, activated Raf/MEK/ERK pathway was observed in human bladder UC specimens from patients with chemoresistant status. In conclusion, TSA elicits a synergistic cytotoxic response in combination with chemotherapy via targeting the Raf/MEK/ERK pathway. TSA elicits synergistic cytotoxic response in combination with three DNA-damaging drugs (cisplatin, gemcitabine, and doxorubicin). Activated Raf/MEK/ERK pathway is involved in chemoresistant mechanism of UC. Combining chemotherapeutic agents with HDAC inhibitor (TSA) or with targeting Raf/MEK/ERK pathway is promising to circumvent chemoresistance in UCs.

PMID- 30288550 TI - Head skeleton malformations in zebrafish (Danio rerio) to assess adverse effects of mixtures of compounds. AB - The EU-EuroMix project adopted the strategy of the European Food Safety Authority (EFSA) for cumulative risk assessment, which limits the number of chemicals to consider in a mixture to those that induce a specific toxicological phenotype. These so-called cumulative assessment groups (CAGs) are refined at several levels, including the target organ and specific phenotype. Here, we explore the zebrafish embryo as a test model for quantitative evaluation in one such CAG, skeletal malformations, through exposure to test compounds 0-120 hpf and alcian blue cartilage staining at 120 hpf, focusing on the head skeleton. Reference compounds cyproconazole, flusilazole, metam, and thiram induced distinctive phenotypes in the head skeleton between the triazoles and dithiocarbamates. Of many evaluated parameters, the Meckel's-palatoquadrate (M-PQ) angle was selected for further assessment, based on the best combination of a small confidence interval, an intermediate maximal effect size and a gentle slope of the dose response curve with cyproconazole and metam. Additional test compounds included in the CAG skeletal malformations database were tested for M-PQ effects, and this set was supplemented with compounds associated with craniofacial malformations or cleft palate to accommodate otherwise organized databases. This additional set included hexaconazole, all-trans-retinoic acid, AM580, CD3254, maneb, pyrimethanil, imidacloprid, pirimiphos-methyl, 2,4-dinitrophenol, 5-fluorouracil, 17alpha-ethynylestradiol (EE2), ethanol, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), PCB 126, methylmercury, boric acid, and MEHP. Most of these compounds produced a dose-response for M-PQ effects. Application of the assay in mixture testing was provided by combined exposure to cyproconazole and TCDD through the isobole method, supporting that in this case the combined effect can be modeled through concentration addition. PMID- 30288551 TI - Single-phase CT angiography: collateral grade is independent of scan weighting. AB - PURPOSE: Collateral grading may vary on single-phase CTA (sCTA) depending on whether the CTA is arterial (A), arteriovenous (AV), or venous (V) weighted. We studied the impact of sCTA weighting on collateral grading using the Tan, MAAS, and Menon methods, and their ability to predict infarct and clinical outcome hypothesizing that AV-weighted sCTA should better predict these outcomes. METHODS: Multicenter retrospective analysis of 212 patients undergoing baseline CTP/sCTA. sCTA weighting was determined by comparing ICA to torcula AV ratios with those from concomitant CTP time-density curves at peak arterial or venous contrast attenuation. A generalized linear mixed model investigated the predictive value for infarct volume or 90-day mRS of the three collateral scores stratified by sCTA weighting and adjusting for age, sex, clot burden score (CBS), and NIHSS. Bayesian information criterion (BIC) differences were calculated between the null and fitted models. RESULTS: Mean age, baseline median NIHSS, ASPECTS, and onset to treatment time were 69.89 +/- 14.45, 13 (6-18), 10 (8-10), and 128 (66-181) minutes. sCTA scans were AV-weighted in 137/212 (65%) and A weighted in 73 (34%). No association was demonstrated between sCTA weighting, hospital site, and sCTA technique. All collateral scores were related to infarct volume irrespective of sCTA weighting, with greatest fit with the regional leptomeningeal score (BIC 18.29, p = 0.0001). No association was shown between sCTA weighting, collateral grade, and clinical outcome. CONCLUSION: sCTA weighting did not significantly impact collateral grade using three common collateral scores or their ability to predict final infarct. PMID- 30288552 TI - Nulliplex-branch, a TERMINAL FLOWER 1 ortholog, controls plant growth habit in cotton. AB - KEY MESSAGE: Nulliplex-branch (nb) mutants in cotton display a specific architecture. The gene responsible for the nb phenotype was identified, and its modulation mode was further studied. Plant architecture is an important agronomic factor influencing various traits such as yield and variety adaptability in crop plants. Cotton (Gossypium) simultaneously displays monopodial and sympodial growth. Nulliplex-branch (nb) mutants showing determinate sympodial shoots have been reported in both G. hirsutum (Ghnb) and G. barbadense (Gbnb). In this study, the gene responsible for the nb phenotype was identified. GhNB and GbNB were found to be allelic loci and are TERMINAL FLOWER 1 orthologs on the Dt subgenome, though the At copies remain native. Sequencing and association analyses identified four (Gh-nb1-Gh-nb4) and one (Gb-nb1) type of point mutation in the coding sequences of Ghnb and Gbnb, respectively. The NB gene was mainly expressed in the root and shoot apex, and expression rhythms were also observed in these tissues, suggesting that the expression of the NB gene could be regulated by photoperiod. Constitutive overexpression of GhNB suppresses the differentiation of the reproductive shoots. Knockout of both copies of GhNB caused the main and lateral shoots to terminate in flowers, which is a more determinate architecture than that of the nb mutants and implies that its function might be dosage dependent. A protein lipid overlay assay indicated that the amino acid substitutions in Gh-nb1 and Gb-nb1 weaken the ligand-binding activity of the NB protein in vitro. These findings suggest that the NB gene plays crucial roles in regulating the determinacy of shoots, and the modulation of this gene should constitute an effective crop improvement approach through adjusting the growth habit of cotton. PMID- 30288553 TI - Genomic selection efficiency and a priori estimation of accuracy in a structured dent maize panel. AB - KEY MESSAGE: Population structure affects genomic selection efficiency as well as the ability to forecast accuracy using standard GBLUP. Genomic prediction models usually assume that the individuals used for calibration belong to the same population as those to be predicted. Most of the a priori indicators of precision, such as the coefficient of determination (CD), were derived from those same models. But genetic structure is a common feature in plant species, and it may impact genomic selection efficiency and the ability to forecast prediction accuracy. We investigated the impact of genetic structure in a dent maize panel ("Amaizing Dent") using different scenarios including within- or across-group predictions. For a given training set size, the best accuracies were achieved when predicting individuals using a model calibrated on the same genetic group. Nevertheless, a diverse training set representing all the groups had a certain predictive efficiency for all the validation sets, and adding extra-group individuals was almost always beneficial. It underlines the potential of such a generic training set for dent maize genomic selection applications. Alternative prediction models, taking genetic structure explicitly into account, did not improve the prediction accuracy compared to GBLUP. We also investigated the ability of different indicators of precision to forecast accuracy in the within- or across-group scenarios. There was a global encouraging trend of the CD to differentiate scenarios, although there were specific combinations of target populations and traits where the efficiency of this indicator proved to be null. One hypothesis to explain such erratic performances is the impact of genetic structure through group-specific allele diversity at QTLs rather than group specific allele effects. PMID- 30288554 TI - Lymphomatoid granulomatosis mimicking cancer and sarcoidosis. AB - Two cases of misdiagnoses of lymphomatoid granulomatosis are discussed here. Lymphomatoid granulomatosis is an Epstein-Barr virus-associated lymphoproliferative disorder with aggressive behavior. Due to its rarity and many presentations, delay in diagnosis and treatment is common. Its histological features including large atypical B-cells, T cell predominance, angiocentricity, necrosis, and evidence of EBV-positive cells should elicit the diagnosis of lymphomatoid granulomatosis. The settings that are described here have not yet been described in the literature. PMID- 30288555 TI - Results of Duodenopancreatic Reoperations in Multiple Endocrine Neoplasia Type 1. AB - BACKGROUND: To evaluate the outcome of duodenopancreatic reoperations in patients with multiple endocrine neoplasia type 1 (MEN1). METHODS: MEN1 patients who underwent reoperations for duodenopancreatic neuroendocrine neoplasms (dpNENs) were retrieved from a prospective database and retrospectively analyzed. RESULTS: Twelve of 101 MEN1 patients underwent up to three reoperations, resulting in a total of 18 reoperations for dpNEN recurrence. Patients initially underwent either formal pancreatic resections (n = 7), enucleations (n = 3), or duodenotomy with lymphadenectomy for either NF-pNEN (seven patients), Zollinger-Ellison syndrome (ZES, three patients), organic hyperinsulinism (one patient) or VIPoma (one patient). Six patients had malignant dpNENs with lymph node (n = 5) and/or liver metastases (n = 2). The indication of reoperations was NF-pNEN (five patients), ZES (five patients), organic hyperinsulinism (one patient), and recurrent VIPoma (one patient). Median time to first reoperation was 67.5 (range 6-251) months. Five patients required a second duodenopancreatic reoperation for 60-384 months after initial surgery, and one patient underwent a third reoperation after 249 months. The rate of complications (Clavien-Dindo >=3) was 28%. Four patients required completion pancreatectomy. Six patients developed pancreoprivic diabetes. After a median follow-up of 18 (6-34) years after initial surgery, ten of 12 patients are alive, one died of metastatic pancreatic VIPoma, and one died of metastatic thymic NEN. CONCLUSION: Reoperations are frequently necessary for dpNEN in MEN1 patients, but are not associated with an increased perioperative morbidity in specialized centers. Organ-sparing resections should be preferred as initial duodenopancreatic procedures to maintain pancreatic function and avoid completion pancreatectomy. PMID- 30288556 TI - C-reactive protein as a biomarker of severe H1N1 influenza. AB - BACKGROUND: C-reactive protein (CRP) is an acute-phase reactant downstream of the pro-inflammatory cytokines released during influenza infection. However, the role of this inflammatory marker in influenza severity and complications is yet to be elucidated. OBJECTIVES: We aim to systematically review and evaluate the levels of CRP in severe and non-severe H1N1 influenza cases and assess its utility as a biomarker in predicting the severity of infection. METHODS: We conducted a comprehensive search in Ovid MEDLINE, Ovid MEDLINE (R) Epub ahead of Print, Embase and Embase Classic to identify human studies reporting measurements of CRP levels in patients infected with H1N1 influenza at various levels of disease severity. RESULTS: Our search identified ten studies eligible for inclusion in this systematic review. The results of the data analysis show that the average CRP levels upon diagnosis were significantly higher (P < 0.05) in patients who developed severe H1N1 influenza compared to their counterparts with a no severe disease. Furthermore, levels of CRP were associated with the degree of H1N1 severity. Subjects with H1N1-related pneumonia and patients who were hospitalized or died of the disease complications, respectively, had 1.4- and 2.5-fold significantly higher CRP levels (P < 0.05) than those with no severe disease outcome. CONCLUSION: CRP levels have been consistently shown to be significantly higher in H1N1 influenza patients who develop a severe disease outcome. The resuts of the present study suggest that serum CRP can be employed-in combination with other biomarkers-to predict the complications of H1N1 influenza.

AB - Until the late twentieth century, it was believed that different sensory modalities were processed by largely independent pathways in the primate cortex, with cross-modal integration only occurring in specialized polysensory areas. This model was challenged by the finding that the peripheral representation of the primary visual cortex (V1) receives monosynaptic connections from areas of the auditory cortex in the macaque. However, auditory projections to V1 have not been reported in other primates. We investigated the existence of direct interconnections between V1 and auditory areas in the marmoset, a New World monkey. Labelled neurons in auditory cortex were observed following 4 out of 10 retrograde tracer injections involving V1. These projections to V1 originated in the caudal subdivisions of auditory cortex (primary auditory cortex, caudal belt and parabelt areas), and targeted parts of V1 that represent parafoveal and peripheral vision. Injections near the representation of the vertical meridian of the visual field labelled few or no cells in auditory cortex. We also placed 8 retrograde tracer injections involving core, belt and parabelt auditory areas, none of which revealed direct projections from V1. These results confirm the existence of a direct, nonreciprocal projection from auditory areas to V1 in a different primate species, which has evolved separately from the macaque for over 30 million years. The essential similarity of these observations between marmoset and macaque indicate that early-stage audiovisual integration is a shared characteristic of primate sensory processing. PMID- 30288558 TI - Rheumatoid pulmonary nodules: clinical and imaging features compared with malignancy. AB - OBJECTIVES: The objective of this study was to identify clinical and imaging features that distinguish rheumatoid lung nodules from malignancy. METHODS: We conducted a retrospective review of 73 rheumatoid patients with histologically proven rheumatoid and malignant lung nodules encountered at Mayo Clinic, Rochester, MN (2001-2016). Medical records and imaging were reviewed including a retrospective blinded review of CT and PET/CT studies. RESULTS: The study cohort had a mean age of 67 +/- 11 years (range 45-86) including 44 (60%) women, 82% with a smoking history, 38% with subcutaneous rheumatoid nodules, and 78% with rheumatoid factor seropositivity. Subjects with rheumatoid lung nodules compared to malignancy were younger (59 +/- 12 vs 71 +/- 9 years, p < 0.001), more likely to manifest subcutaneous rheumatoid nodules (73% vs 20%, p < 0.001) and rheumatoid factor seropositivity (93% vs 68%, p = 0.034) but a history of smoking was common in both groups (p = 0.36). CT features more commonly associated with rheumatoid lung nodules compared to malignancy included multiplicity, smooth border, cavitation, satellite nodules, pleural contact, and a subpleural rind of soft tissue. Optimal sensitivity (77%) and specificity (92%) (AUC 0.85, CI 0.75 0.94) for rheumatoid lung nodule were obtained with >= 3 CT findings (>= 4 nodules, peripheral location, cavitation, satellite nodules, smooth border, and subpleural rind). Key 18FDG-PET/CT features included low-level metabolism (SUVmax 2.7 +/- 2 vs 7.2 +/- 4.8, p = 0.007) and lack of 18F-fluorodeoxyglucose (FDG) avid draining lymph nodes. CONCLUSION: Rheumatoid lung nodules have distinct CT and PET/CT features compared to malignancy. Patients with rheumatoid lung nodules are younger and more likely to manifest subcutaneous rheumatoid nodules and seropositivity. KEY POINTS: * Rheumatoid lung nodules have distinct clinical and imaging features compared to lung malignancy. * CT features of rheumatoid lung nodules include multiplicity, cavitation, satellite nodules, smooth border, peripheral location, and subpleural rind. * Key PET/CT features include low-level metabolism and lack of FDG-avid draining lymph nodes. PMID- 30288560 TI - The current status of MRI in the pre-operative assessment of intramedullary conventional appendicular osteosarcoma. AB - Osteosarcoma is the commonest primary malignant bone tumour in children and adolescents, the majority of cases being conventional intra-medullary high-grade tumours affecting the appendicular skeleton. Treatment is typically with a combination of neo-adjuvant chemotherapy, tumour resection with limb reconstruction and post-operative chemotherapy. The current article reviews the role of magnetic resonance imaging (MRI) in the pre-operative assessment of high grade central conventional osteosarcoma. PMID- 30288559 TI - Cognitive-behavioral therapy effects on alerting network activity and effective connectivity in panic disorder. AB - Given the particular relevance of arousal and alerting in panic disorder (PD), here the alerting network was investigated (1) contrasting patients with PD and healthy controls, (2) as a function of anxiety sensitivity constituting a dimensional measure of panic-related anxiety, and (3) as a possible correlate of treatment response. Using functional magnetic resonance imaging (fMRI), 45 out patients with PD (f = 34) and 51 matched healthy controls were investigated for brain activation patterns and effective connectivity (Dynamic Causal Modeling, DCM) while performing the Attention Network Task (ANT). Anxiety sensitivity was ascertained by the Anxiety Sensitivity Index (ASI). Forty patients and 48 controls were re-scanned after a 6 weeks cognitive-behavioral treatment (CBT) or an equivalent waiting time, respectively. In the alerting condition, patients showed decreased activation in fronto-parietal pathways including the middle frontal gyrus and the superior parietal lobule (MFG, SPL). In addition, ASI scores were negatively correlated with connectivity emerging from the SPL, the SFB and the LC and going to the MFG in patients but not in healthy controls. CBT resulted in an increase in middle frontal and parietal activation along with increased connectivity going from the MFG to the SPL. This change in connectivity was positively correlated with reduction in ASI scores. There were no changes in controls. The present findings point to a pathological disintegration of the MFG in a fronto-parietal pathway in the alerting network in PD which was observed to be reversible by a successful CBT intervention. PMID- 30288561 TI - Caballeronia ginsengisoli sp. nov., isolated from ginseng cultivating soil. AB - A Gram-stain-negative, strictly aerobic, non-motile, ivory colored and rod-shaped bacterium (designated Gsoil 652T) isolated from ginseng cultivating soil, was characterized using a polyphasic approach to clarify its taxonomic position. Strain Gsoil 652T was observed to grow optimally at 30 degrees C and at pH 7.0 on R2A agar medium. Phylogenetic analysis, based on 16S rRNA gene sequences similarities, indicated that Gsoil 652T belongs to the genus Caballeronia of the family Burkholderiaceae and was most closely related to Caballeronia choica LMG 22940T (98.9%), Caballeronia udeis LMG 27134T (98.9%), Caballeronia sordidicola LMG 22029T (98.2%) and Caballeronia humi LMG 22934T (98.1%). The DNA G+C content was 62.1 mol% and Q-8 was the major isoprenoid quinone. The main polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, unidentified aminophospholipid, and unidentified phospholipid. The predominant fatty acids were C16:0, C17:0 cyclo and C19:0 cyclo omega8c. The DNA-DNA relatedness value between strain Gsoil 652T and closely related type strains of Caballeronia species were less than 36.0%. Moreover, strain Gsoil 652T could be distinguished phenotypically from the recognized species of the genus Caballeronia. The novel isolate, therefore, represents a novel species, for which the name Caballeronia ginsengisoli sp. nov. is proposed, with the type strain Gsoil 652T (= KACC 19441T = LMG 30326T). PMID- 30288562 TI - Isolation and identification of Ammodendron bifolium endophytic bacteria and the action mechanism of selected isolates-induced seed germination and their effects on host osmotic-stress tolerance. AB - This study aimed to identify Ammodendron bifolium endophytic bacteria, and to evaluate promoting mechanism of selected isolates on seed germination and their effects on host osmotic-stress tolerance. Forty-five strains were isolated from A. bifolium and were classified into 13 different genera by 16S rDNA gene sequence analysis. AY3, AY9 and AG18, which were identified as Staphylococcus, Kocuria, Bacillus sp., promoted host seed ethylene release during germination. Ethrel and 1-aminocyclopropane-1-carboxylic acid (ACC) imitated the effect of AY3, AY9 and AG18 on seed germination. The data suggest that ethylene mediates AY3-, AY9-, AG18-induced A. bifolium seed germination. In addition, osmotic stress prevented seed germination and radicle elongation. However, the inhibitory effect of osmotic stress on seed germination and radicle elongation were rescued by AY3, AY9 and AG18. The results show that AY3, AY9 and AG18 increased osmotic stress tolerance in A. bifolium. AY3, AY9, AG18 induced A. bifolium seed germination through promoting ethylene production during endophytic bacteria plant interaction, and increase osmotic-stress tolerance in A. bifolium. AY3, AY9 and AG18 are potential candidates for the protection of A. bifolium. PMID- 30288563 TI - Oral Isotretinoin in the Treatment of Postoperative Edema in Thick-Skinned Rhinoplasty: A Randomized Placebo-Controlled Clinical Trial. AB - BACKGROUND: The thick-skinned nose is still one of the most challenging aspects of rhinoplasty. The possible effects of oral isotretinoin on cosmetic results of rhinoplasty in patients with thick nasal skin have been considered during recent years. METHODS: In this double-blind placebo-controlled clinical trial, 48 cases were divided into two groups randomly. Oral isotretinoin (0.5-mg/kg) was started on the 31st day after surgery and given every other day for 1 month and after that daily for two additional months in the first group. The second group received a placebo in the same form, sequence and interval as the first group. The cosmetic results based on patient satisfaction and ranking by an expert surgeon were compared between the two groups at 3 months, 6 months and 1 year after surgery. RESULTS: Patient satisfaction and ranking by an expert surgeon in the isotretinoin group at 3 months and 6 months after surgery were significantly better than in the placebo group (p value < 0.05); however, at 12 months after surgery there was no statistically significant difference between the two groups (p value > 0.05). CONCLUSION: Though postoperative use of oral isotretinoin in patients with thick nasal skin accelerates improvement in cosmetic results during the early months after surgery, it does not significantly affect the final cosmetic result 1 year after surgery.

PMID- 30288564 TI - The Ideals of Facial Beauty Among Chinese Aesthetic Practitioners: Results from a Large National Survey. AB - : As the demand for cosmetic procedures increases, the importance of patient centred care in this field becomes more prominent. The aesthetic practitioners' ideals of beauty, in addition to their knowledge and perception of patients' ideals of beauty and expectations, are important during doctor-patient communication. These are important in strengthening practices of patient-centred communication and treatment. This study was conducted to investigate ideals of facial beauty among Chinese aesthetic practitioners. A questionnaire with simple sketches of facial features was given to aesthetic practitioners in Chinese cosmetology hospitals and clinics to assess aesthetic practitioners' ideals of beauty and their preferences for facial shapes, facial profile, nose and lip shape, jaw angle, and chin shape. A total of 596 surveys were completed. This survey revealed that Chinese aesthetic practitioners preferred a heart/inverted triangular facial shape with a reduced lower face height, a straight and small nose, as well as lips that are full medially and taper off laterally with well defined borders and Cupid's bow. An obtuse jaw angle for women and a square well defined jaw angle for men, and a round and pointy chin for both women and men were the most preferred. A majority (66.7%) of the respondents said they would have plastic surgery. However, if given the choice 82.9% indicated they would opt for non-surgical procedures. Finally, a clear majority (90.5%) believed that being beautiful would improve their daily life. The results were then compared to a similar previous study in which the same ideals of beauty were investigated among Chinese laypersons. This information will help the aesthetic professionals to understand their patient's requests and expectations better and therefore aid in offering and providing treatments that are in line.

PMID- 30288565 TI - Complication of Ruptured Poly Implant Prothese(r) Breast Implants Combined with AQUAfilling(r) Gel Injection: A Case Report and Literature Review. AB - INTRODUCTION: We describe the first case of a patient who received AQUAfilling(r) gel (Biomedica, Prague, Czech Republic) after augmentation with Poly Implant Prothese(r) (PIP) breast implants and later developed breast deformity with bilateral implant rupture. CASE REPORT: A 49-year-old Korean female patient who received breast augmentation with PIP implants 18 years ago and subsequent insertion of AQUAfilling(r) gel 1 year ago visited our center with a chief complaint of pain and decreased implant sizes in both breasts. Breast implant and foreign body removal operation was performed for both breasts under general anesthesia. Intraoperative gross findings, pathologic findings, and tissue culture results were analyzed. RESULTS: Our diagnosis included rupture of the implants in both breasts with leakage of injected material resulting in inflammation of the pericapsular area and pectoralis muscle. The intraoperative gross findings and results of the pathologic report showed that the implants were exposed with massive leakage of AQUAfilling(r) gel in the pericapsular space, and the pectoralis major was mixed with AQUAfilling(r) gel-like liquid and tissue with an inflammatory reaction. CONCLUSIONS: Surgeons should be careful in performing AQUAfilling(r) gel injection for breast augmentation, especially when combined with breast implant insertion. AQUAfilling(r) gel itself is not yet proven safe in the long term, so more research on this topic is warranted. Additionally, surgeons should be aware of the comparatively high risk of implant rupture and foreign body reaction with PIP implants, and warn patients accordingly.

PMID- 30288566 TI - Comparison of leg loader and treadmill exercise for evaluating patients with peripheral artery disease. AB - The exercise ankle-brachial index (ABI) helps diagnose lower extremity peripheral artery disease (PAD). Patients with comorbidities may be unable to perform treadmill exercise, the most common stress loading test. While the active pedal plantar flexion (APP) test using the leg loader, simple and easy stress loading device, could be an alternative, there are no data comparing the leg loader and treadmill exercise. Therefore, we aimed to compare APP using the leg loader and treadmill exercise to evaluate PAD. A total of 27 patients (54 limbs) diagnosed with PAD with intermittent claudication and considered for angiography and/or endovascular treatment were recruited prospectively, and both the leg loader and treadmill were performed. There was a strong correlation (r = 0.925, p < 0.001) between the leg loader ABI and treadmill ABI; however, the decrease rate of the leg loader ABI was significantly less than that of treadmill ABI (14.0% [5.6, 30.1] vs. 25.8% [6.1, 53.1], p < 0.001). The number of patients who terminated the exercise prematurely due to dyspnea was four during the treadmill and zero during the leg loader. There was a good correlation between the leg loader ABI and treadmill ABI. Although leg loader, a simple, safe, and easy method, could be an alternative to diagnose PAD, further studies are needed to evaluate the diagnostic value of the leg loader in patients with borderline ABI or those unable to perform the treadmill. PMID- 30288567 TI - Prevalence of early repolarization syndrome and long-term clinical outcome in patients with the diagnosis of idiopathic ventricular fibrillation. AB - Idiopathic ventricular fibrillation (IVF) is diagnosed in up to 14% of sudden cardiac death (SCD) survivors. Early repolarization syndrome (ERS) in patients with ventricular tachyarrhythmia is characterized by an elevated J-point in inferior and/or antero-lateral leads. Our objectives were to determine the prevalence of ERS in IVF patients, and to evaluate potential differences in clinical outcome. Out of 3,552 implantable cardioverter defibrillator (ICD) carriers, 758 SCD survivors were retrospectively identified from the databases of the Medical Universities of Vienna and Innsbruck within the last three decades. Early repolarization pattern (ERP) was classified either as "notching" or "slurring". Endpoints were defined as appropriate ICD therapies for ventricular tachyarrhythmia, either anti-tachycardia pacing or shock, and all-cause mortality. After exclusion of recognized reasons for SCD, 50 patients were assigned to the diagnosis of IVF (6.6%). An ERP was identified in 10 patients, most of them with notching (n = 8). After a mean follow-up of 11.2 +/- 6.7 years (539.3 patient years), appropriate ICD therapies were found in 50% of ERS and 43% of IVF patients without ERP (p = 0.732). In ERS patients, all ICD therapies were found in patients with notching pattern. Similarly, incidence of inappropriate ICD therapies, and all-cause mortality was comparable (30% vs. 23%, p = 0.707; 10% vs. 5%, p = 0.496, respectively). In 758 SCD survivors, we found a low prevalence of IVF and ERS. Similar event rates were reported concerning all-cause mortality and ICD therapies for ventricular tachyarrhythmia after long-term follow-up in this cohort. PMID- 30288568 TI - Abnormal tibial alignment is a risk factor for lateral meniscus posterior root tears in patients with anterior cruciate ligament ruptures. AB - PURPOSE: The purpose of this study was to identify if abnormal tibial alignment was a risk factor for lateral meniscus posterior root tears (LMPRT) in patients with acute anterior cruciate ligament (ACL) ruptures. METHODS: The medical charts of 200 patients treated for ACL ruptures between 2013 and 2016 were retrospectively reviewed and evaluated. MRI images and reports were assessed for concurrent meniscal tears. Radiographs were reviewed for tibia vara and tibial slope angles and MRI reports identifying lateral root tears were compared to intraoperative reports to determine accuracy. Multiple logistic regression models were constructed to identify potential risk factors for LMPRTs. RESULTS: Of the 200 patients reviewed, a total of 97 individuals with concurrent meniscal injuries were identified. In patients sustaining a concurrent meniscal injury, there was a 4% incidence of medial meniscus posterior root tears and a 10.3% incidence of LMPRTs. Patients sustaining an ACL injury with an LMPRT were found to have greater tibia vara angles (4.2 +/- 1.0 vs. 2.9 +/- 1.7; p = 0.024), increased tibial slopes (12.6 +/- 1.5 vs. 10.7 +/- 2.9; p = 0.034), and higher BMIs (27.3 +/- 2.9 vs. 25.3 +/- 5.9; p = 0.034) when compared to patients without meniscus tears. There was low agreement between MRI and arthroscopic findings (kappa rate = 0.54). Multiple logistic regression analysis demonstrated that a tibia vara angle > 3 was associated with a 5.2-fold increase (95% CI 0.99-27.01; p = 0.050), and a tibial slope > 12 with a 5.4-fold increase (95% CI 1.03-28.19; p = 0.046) in LMPRTs. CONCLUSIONS: Patients with greater tibia varus angles, increased tibial slopes, and higher BMIs were found to have an increased risk of LMPRTs when sustaining an ACL rupture. There was a low rate of agreement between MRI and arthroscopy in identifying LMPRTs. In patients with ACL ruptures who have abnormal tibial alignment or increased BMI, physicians should be watchful for lateral meniscus posterior root tears. LEVEL OF EVIDENCE: 3. PMID- 30288569 TI - A load-measuring device can achieve fine-tuning of mediolateral load at knee arthroplasty but may lead to a more lax knee state. AB - PURPOSE: A balanced knee arthroplasty should optimise survivorship and performance. Equilibration of medial and lateral femorotibial load requires guided judicious pericapsular ligament release. The null hypothesis was that there would be no difference between use of a tensiometer device and a remote load sensor final load transfer across the joint through functional arc of motion. METHODS: A cadaveric study, using eight knees, was performed to define the impact of an established gap distraction device against load sensor-aimed soft tissue release in a TKA setting. Using validated measures of laxity in six degrees of freedom and true real-time load sensing four states were examined: native knee, TKA using spacer blocks (TKA), TKA with soft tissue release aided by a monogram tensiometer (TKA-T) and finally where load across the tibiofemoral articulation remains unbalanced final soft tissue release using a sensor device (TKA-OS). RESULTS: The laxity pattern was equivalent for TKA-T and TKA-OS. However, in only four of these seven knees despite the tensiometer confirming equivalence of rectangular flexion-extension gap dimensions and centralisation of collateral ligament distraction, there remained a > 15lb medial to lateral load difference for at least one point of the flexion arc. This was corrected by further final soft tissue release guided by the OS sensor device in the final three knees. CONCLUSION: Tensiometer-guided soft tissue release at two points of flexion failed to achieve balance for three out of seven knee arthroplasty procedures. Sensor technology guided final soft tissue balancing to equilibrate load across the joint through full arc of motion. This work argues for the role of continuous sensor readings to guide the soft tissue balancing during total knee arthroplasty. PMID- 30288570 TI - Pre-existing patellofemoral disease does not affect 10-year survivorship in fixed bearing unicompartmental knee arthroplasty. AB - PURPOSE: The purpose of this study was to assess 10-year functional outcome and survivorship analysis of patients with significant radiographic evidence of patellofemoral joint arthritis treated with fixed bearing unicompartmental knee arthroplasty. METHODS: Two hundred and sixteen patients (263 knees) that underwent UKA from 2003 to 2005 for a mean of 10.5 +/- 2.1 years were prospectively followed up. Preoperative radiological assessment of the patellofemoral joint state was assessed according to the Ahlback classification by an independent assessor and radiographically significant patellofemoral disease was defined as grade 2 or more. Patients with significant bone-on-bone contact in the patellofemoral joint were excluded. RESULTS: Of the 263 knees, 222 (84.4%) had normal patellofemoral joint state and 41 (15.6%) radiologically significant patellofemoral disease. At 10 years' follow-up, the normal and patellofemoral groups had similar OKS (20 +/- 7 vs 20 +/- 8, n.s.) and KSS scores (79 +/- 20 vs 81 +/- 20, n.s.), respectively. There were 12 revision surgeries in the normal group and the most common indication for revision was progression of contralateral compartment osteoarthritis (6 of 12 cases). There was only one revision in the patellofemoral group and it was due to progression of contralateral compartment osteoarthritis (n.s.). When all secondary surgeries to the operated knee were considered as failures, the 10-year survival rate was 95.1% (CI 95%: 92.2-97.7%). CONCLUSION: The presence of significant preoperative radiological patellofemoral disease does not affect long-term implant survival and patients have excellent functional outcomes 10 years postoperatively. These patients should not be contraindicated from undergoing unicompartmental knee arthroplasty. LEVEL OF EVIDENCE: III. PMID- 30288572 TI - Serum kidney injury molecule 1 and beta2-microglobulin perform as well as larger biomarker panels for prediction of rapid decline in renal function in type 2 diabetes. AB - AIMS/HYPOTHESIS: As part of the Surrogate Markers for Micro- and Macrovascular Hard Endpoints for Innovative Diabetes Tools (SUMMIT) programme we previously reported that large panels of biomarkers derived from three analytical platforms maximised prediction of progression of renal decline in type 2 diabetes. Here, we hypothesised that smaller (n <= 5), platform-specific combinations of biomarkers selected from these larger panels might achieve similar prediction performance when tested in three additional type 2 diabetes cohorts. METHODS: We used 657 serum samples, held under differing storage conditions, from the Scania Diabetes Registry (SDR) and Genetics of Diabetes Audit and Research Tayside (GoDARTS), and a further 183 nested case-control sample set from the Collaborative Atorvastatin in Diabetes Study (CARDS). We analysed 42 biomarkers measured on the SDR and GoDARTS samples by a variety of methods including standard ELISA, multiplexed ELISA (Luminex) and mass spectrometry. The subset of 21 Luminex biomarkers was also measured on the CARDS samples. We used the event definition of loss of >20% of baseline eGFR during follow-up from a baseline eGFR of 30-75 ml min-1 [1.73 m] 2. A total of 403 individuals experienced an event during a median follow-up of 7 years. We used discrete-time logistic regression models with tenfold cross validation to assess association of biomarker panels with loss of kidney function. RESULTS: Twelve biomarkers showed significant association with eGFR decline adjusted for covariates in one or more of the sample sets when evaluated singly. Kidney injury molecule 1 (KIM-1) and beta2-microglobulin (B2M) showed the most consistent effects, with standardised odds ratios for progression of at least 1.4 (p < 0.0003) in all cohorts. A combination of B2M and KIM-1 added to clinical covariates, including baseline eGFR and albuminuria, modestly improved prediction, increasing the area under the curve in the SDR, Go-DARTS and CARDS by 0.079, 0.073 and 0.239, respectively. Neither the inclusion of additional Luminex biomarkers on top of B2M and KIM-1 nor a sparse mass spectrometry panel, nor the larger multiplatform panels previously identified, consistently improved prediction further across all validation sets. CONCLUSIONS/INTERPRETATION: Serum KIM-1 and B2M independently improve prediction of renal decline from an eGFR of 30-75 ml min-1 [1.73 m]-2 in type 2 diabetes beyond clinical factors and prior eGFR and are robust to varying sample storage conditions. Larger panels of biomarkers did not improve prediction beyond these two biomarkers. PMID- 30288575 TI - ? PMID- 30288574 TI - [Boys' consultation-support for boys with problems during puberty].

AB - Mechanisms involved in fine adaptation of fungi to their environment include differential gene regulation associated with single nucleotide polymorphisms and indels (including transposons), horizontal gene transfer, gene copy amplification, as well as pseudogenization and gene loss. The two Podospora genome sequences examined here emphasize the role of pseudogenization and gene loss, which have rarely been documented in fungi. Podospora comata is a species closely related to Podospora anserina, a fungus used as model in several laboratories. Comparison of the genome of P. comata with that of P. anserina, whose genome is available for over 10 years, should yield interesting data related to the modalities of genome evolution between these two closely related fungal species that thrive in the same types of biotopes, i.e., herbivore dung. Here, we present the genome sequence of the mat + isolate of the P. comata reference strain T. Comparison with the genome of the mat + isolate of P. anserina strain S confirms that P. anserina and P. comata are likely two different species that rarely interbreed in nature. Despite having a 94-99% of nucleotide identity in the syntenic regions of their genomes, the two species differ by nearly 10% of their gene contents. Comparison of the species-specific gene sets uncovered genes that could be responsible for the known physiological differences between the two species. Finally, we identified 428 and 811 pseudogenes (3.8 and 7.2% of the genes) in P. anserina and P. comata, respectively. Presence of high numbers of pseudogenes supports the notion that difference in gene contents is due to gene loss rather than horizontal gene transfers. We propose that the high frequency of pseudogenization leading to gene loss in P. anserina and P. comata accompanies specialization of these two fungi. Gene loss may be more prevalent during the evolution of other fungi than usually thought. PMID- 30288582 TI - Shear wave elastography prior to transjugular intrahepatic portosystemic shunt may predict the decrease in hepatic vein pressure gradient. AB - BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure used to treat portal hypertension complications. Our aim was to evaluate liver and spleen stiffness measurement (LSM and SSM, respectively) changes using acoustic radiation force impulse imaging (ARFI) in comparison to Child-Pugh scores for predicting hepatic venous pressure gradient (HVPG) decreases after TIPS implantation. METHODS: This prospective study included 31 consecutive clinically significant portal hypertension patients with TIPS indication. All patients received LSM and SSM before TIPS, at baseline, 2 days (follow-up 1) and 6 weeks (follow-up 2) post-implantation. HVPG was performed during the TIPS procedure. RESULTS: The mean decrease in HVPG after TIPS was 63%. LSM and SSM decreased significantly between baseline and follow-up 2 (p < 0.001 and p < 0.001, respectively). At baseline, follow-up 1 and follow-up 2, significant correlations were detected between mean SSM and mean HVPG (p = 0.026; p = 0.018; p = 0.002, respectively). HVPG decreased to <= 10 mmHg in 61% of patients for which LSM, SSM, and Child-Pugh score were predictors (p = 0.033, p = 0.002 and p = 0.030, respectively). The area under the curve (AUC) for LSM, SSM, and Child Pugh was 0.88, 0.90, and 0.84, respectively, with close sensitivity and specificity. SSM had the highest diagnostic accuracy for predicting an HVPG decrease to <= 10 mmHg in comparison to LSM and Child-Pugh score. CONCLUSION: Spleen stiffness is superior to liver stiffness and Child-Pugh score as a non invasive surveillance tool for evaluating patients with clinically significant portal hypertension (HVPG >= 10 mmHg) prior to TIPS.

AB - The American Diabetes Association and the European Association for the Study of Diabetes convened a panel to update the prior position statements, published in 2012 and 2015, on the management of type 2 diabetes in adults. A systematic evaluation of the literature since 2014 informed new recommendations. These include additional focus on lifestyle management and diabetes self-management education and support. For those with obesity, efforts targeting weight loss, including lifestyle, medication and surgical interventions, are recommended. With regards to medication management, for patients with clinical cardiovascular disease, a sodium-glucose cotransporter-2 (SGLT2) inhibitor or a glucagon-like peptide-1 (GLP-1) receptor agonist with proven cardiovascular benefit is recommended. For patients with chronic kidney disease or clinical heart failure and atherosclerotic cardiovascular disease, an SGLT2 inhibitor with proven benefit is recommended. GLP-1 receptor agonists are generally recommended as the first injectable medication. PMID- 30288584 TI - The little rose sign.

AB - Imaging has a central role in surveillance of cervical cancer, guiding decision on when to initiate treatment for recurrent disease and to guide management in advanced cervical cancer. Due to the increased availability of pelvic radiation therapy, the rate of atypical presentation of recurrent disease has increased. Simultaneously, the array of systemic therapies now available for advanced cervical cancer has considerably expanded in the last few years, with therapies now available in mid and low-income countries. While pelvic recurrences are amenable of loco-regional treatment, recurrent disease may present with metastases to the thoracoabdominal organs, lymph nodes, bones, skin and brain, for which systemic treatment represent the standard of care. Besides combined chemotherapy regimens, alternative chemotherapies, biosimilars and immune checkpoint inhibitors are now available, each associated with a definite pattern of response and toxicity. In this review, after describing the typical and atypical presentations of recurrent and advanced cervical carcinoma on cross sectional imaging, we will discuss systemic treatment for recurrent or advanced disease and their associated radiographic sequelae, in light of the newly available therapies. PMID- 30288586 TI - Effect of thyme essential oil against Bacillus cereus planktonic growth and biofilm formation. AB - The objective of this study was to determine the effect of thyme essential oil (TEO) on the planktonic growth and biofilm formation of Bacillus cereus (B. cereus). GC-MS analysis of TEO allowed the detection of 13 compounds, and the major constituents were p-cymene (29.7%), thymol (23.73%), gamma-terpinene (16.21%), and 1,8-cineole (9.74%). TEO exhibited a minimum inhibitory concentration (MIC) value against planktonic B. cereus of 0.25 mg/mL. The potent effect of TEO to inhibit the growth of planktonic B. cereus was due to cell membrane damage, as evidenced by reduced cell viability, protein changes, decreased intracellular ATP concentration, increased extracellular ATP concentration and cell membrane depolarization, and cellular morphological changes. In addition, TEO exerted a significant inhibitory effect on B. cereus biofilm formation, as confirmed by environmental scanning electron microscopic images. These findings suggested that TEO has the potential to be developed as a natural food additive to control foodborne contamination associated with B. cereus and its biofilm. PMID- 30288587 TI - A new strategy for fed-batch process control of HEK293 cell cultures based on alkali buffer addition monitoring: comparison with O.U.R. dynamic method. AB - The increasing demand for biopharmaceuticals produced in mammalian cells has driven the industry to enhance productivity of bioprocesses through different strategies. This is why fed-batch and perfusion cultures are considered more attractive choices than batch processes. In this context, the availability of reliable online measuring systems for cell density and metabolic activity estimation will help the application of these processes. The present work focuses on the comparison of two different monitoring tools for indirect estimation of biomass concentration in a HEK293 cell cultures producing IFN-gamma: on one side, the oxygen uptake rate (O.U.R.) determination, by means of application of the dynamic method measurement which is already a widely used tool and, on the other side, a new robust online monitoring tool based on the alkali buffer addition used to maintain the pH set point. Both strategies allow a proper monitoring of cell growth and metabolic activity, with precise identification of the balanced cell growth and the most important action in the process, as is the media feeding. The application of these monitoring systems in fed-batch processes allows extending the growth of HEK293 cells, which in turn results in higher final cell concentrations compared with Batch strategy (7 . 106 cells mL-1), achieving 14 . 106 cells mL-1 for the fed-batch based on O.U.R. and 19 . 106 cells mL-1 for the fed-batch based on the alkali addition. Product titter is also increased in respect of the batch strategy (3.70 mg L-1), resulting in 8.27 mg L 1 when fed-batch was based on O.U.R. and 11.49 mg L-1 when it was based on the alkali buffer strategy. Results prove that fed-batch strategy based on the alkali buffer addition is a robust online monitoring method that has shown its great potential to optimize the feeding strategy in HEK293 fed-batch cultures. PMID- 30288588 TI - Radiofrequency Wire Recanalization of Chronically Occluded Venous Stents: A Retrospective, Single-Center Experience in 15 Patients. AB - INTRODUCTION: Chronically occluded venous stents may be difficult to salvage, necessitating multiple approaches and adjunctive techniques. Radiofrequency wires have been used to cross chronic obstructions in a variety of settings. Herein, radiofrequency wire recanalization (RFWR) of chronically occluded venous stents is presented. MATERIALS AND METHODS: Fifteen patients (8 males; 7 females) aged 23-74 years (median 42 years) underwent prior venous stenting in the setting of venous occlusions. Seven had an underlying coagulopathy, three had May-Thurner syndrome, three had provoked deep venous thrombosis, one had a dialysis fistula, and one had pacer leads in situ. All indwelling venous stents were chronically occluded and symptomatic. Out of 15 patients, 13 (87%) had iliocaval venous stents, while two (13%) had superior vena cava and/or upper extremity venous stents. After failing conventional and blunt recanalization techniques, RFWR was performed to traverse the chronic occlusions. Technical success and complications were recorded. RESULTS: Fifteen patients underwent 19 procedures. Twelve patients underwent one procedure, two patients had two procedures, and one patient had three procedures. RFWR alone was used in 12/19 (63%) procedures, while 7/19 (37%) required adjunctive sharp recanalization techniques. Technical success or crossing of the occlusion with flow restoration through the occluded segments was achieved in 17/19 (89%). One major and one minor complication occurred. CONCLUSION: Radiofrequency wire recanalization is an effective adjunct to revise chronically occluded venous stents, potentially increasing procedural success in challenging cases. PMID- 30288589 TI - Ablation Volume Measurement After Percutaneous Cryoablation Using a Two-cryo probe Technique for Small Hepatocellular Carcinomas. AB - PURPOSE: To calculate the ablation volume of percutaneous cryoablation (PCA) with a two-cryo-probe technique for small hepatocellular carcinomas (HCCs) and to assess risk factors for local tumor recurrence (LTR). MATERIALS AND METHODS: Between January 2013 and June 2017, 96 patients (mean age, 60.7 years; range, 37 83 years) with 106 small HCCs were retrospectively analyzed. The ablation volume, technical success, LTR rates, and complications were evaluated. Ablation volume was measured after the first freezing and immediately after completing PCA twice via computed tomography imaging. Prognostic factors associated with LTR were analyzed. RESULTS: Technical success was achieved in all patients. The mean final ablation volume was 19.1 +/- 4.8 cm3, which was significantly higher than the first freezing ablation volume (14.7 +/- 4.3 cm3, p < 0.001). During the median follow-up period of 16.7 months (range, 5-52 months), LTR-free survival rates based on Kaplan-Meier analyses at 6 months, 1 year, and 2 years were 87.7%, 84.0%, and 80.2%, respectively. Only one major complication of post-procedural arterial bleeding occurred. A final ablation volume/tumor volume < 10 was a significant risk factor for LTR (p = 0.044). CONCLUSIONS: A ratio of final ablation volume to tumor volume < 10 was a significant prognostic factor for LTR. Therefore, the measurement and prediction of the final ablation volume are important to reduce LTR. PMID- 30288590 TI - Long-Term Evaluation of Percutaneous Groin Access for EVAR. AB - BACKGROUND: Percutaneous endovascular aneurysm repair (PEVAR) has been shown to have high success rates, shorter operating times and length of stay compared to open access. However, there exists a lack of long-term follow-up data on these patients, and questions remain regarding longer-term outcomes. This study aims to assess the long-term complications and evolution of accessed vessels post-PEVAR. METHODS: Sixty-one cases of bilateral PEVAR (122 groins) with > 36 months follow up were analysed. Vessel diameter, calcification, dissection, lymphocele, pseudoaneurysm and thrombus formation were reviewed at 30th day and at the most recent follow-up CT. Notes were reviewed for groin infections, haematomas and nerve injury. Complications were considered 'major' if they required intervention or treatment. RESULTS: Mean follow-up time from procedure to most recent scan was 49.9 months. There were no major short- or long-term complications. The early complication rate was 9.8%, with six pseudoaneurysms, four dissections, one thrombus, one nerve injury and no lymphoceles, haematomas or groin infections. The long-term complication rate was 0.8%, with only one pseudoaneurysm. The remainder of early complications resolved naturally without intervention. Accessed vessel showed significantly (P <= 0.05) increased diameter and calcification between 30th day and last follow-up scan. CONCLUSION: This study provides the largest clinical cohort and the longest mean follow-up time reported in the literature and demonstrates the long-term safety of PEVAR. PEVAR has a very low long-term complication rate, without any major complications in our cohort. The accessed common femoral arteries do not show stenosis or thrombosis. Minor short-term complications appear to gradually resolve without intervention. Larger multi-centre studies are recommended. PMID- 30288591 TI - Uterine Artery Embolization in Women with Symptomatic Cervical Leiomyomata: Efficacy and Safety. AB - PURPOSE: To perform an evaluation on safety and efficacy of uterine artery embolization (UAE) in the patients with symptomatic cervical leiomyomata. METHODS: Patients with symptomatic cervical leiomyomata who underwent UAE in one specialized hospital were retrospectively analyzed, both clinically and with MR imaging. The 3-month outcomes were assessed with MR imaging and a validated questionnaire. Long-term follow-up was assessed by direct contact or file review. To determine the efficacy of UAE for cervical leiomyomata, the primary objective was to assess the clinical outcome with the UFS-QOL questionnaire, containing the health-related quality of life (HRQOL) and symptom severity score (SSS). To assess safety, the secondary objective included leiomyomata volume reduction, the infarction/complication rate and secondary interventions were needed. RESULTS: Between 2006 and 2017, eight of 1180 patients underwent UAE and were eligible for inclusion. All embolizations were technically successful (n = 8). At 3 months, all patients showed cervical leiomyomata volume reduction with a median reduction of 41.5% (38.8 cm3) compared to baseline (p = 0.012). No complications occurred. At a median follow-up of 3 months (range 1-7, n = 7), the HRQOL and SSS improved with a median difference of 13 points (range - 5 to 60, p = 0.063) and - 13 points (range - 79 to 3, p = 0.046), respectively. Long-term follow-up showed two secondary interventions (median of 43.5 months). Six patients reported no symptom recurrence. CONCLUSION: UAE in women with symptomatic cervical leiomyomata is effective and safe with significant improvement in symptoms and quality of life. UAE is a valuable option for women seeking a non-surgical solution. PMID- 30288592 TI - Factors Associated with Secondary Functional Patency After Percutaneous Transluminal Angioplasty of the Early Failing or Immature Hemodialysis Arteriovenous Fistula. AB - PURPOSE: To evaluate the efficacy of percutaneous transluminal angioplasty for early failing hemodialysis arteriovenous fistulas (AVFs) and predictors of secondary functional patency (FP). METHODS: A review of our endovascular registry database showed that 61 patients with early failure after a surgically created AVF underwent endovascular intervention between 2011 and 2016. Median time from AVF creation to first intervention was 5.6 weeks. Median duration of follow-up was 14 months. Items related to the technical success rate and primary and secondary FP, and factors associated with secondary FP were analyzed. RESULTS: Technical success was achieved in 55 (90%) of 61 patients. The primary and secondary FP rates were 42% and 65% at 12 months, respectively. Multivariate analysis showed that lesion length (HR; 1.15, P = 0.001) and lesions including juxta-AVF (the portion of fistula vein within 2 cm of the arteriovenous anastomosis, HR; 6.23, P = 0.008) were factors associated with reduced secondary FP. ROC curve analysis indicated lesion length with cutoff value >= 9 cm as a risk factor for reduced secondary FP. Secondary FP at 12 months for patients with no risk factors, with 1, and with 2 was 86%, 65%, and 0%, respectively. There was a significant difference in secondary FP rates among these groups (P = 0.001). CONCLUSIONS: A lesion length and juxta-AVF lesion are the risk factors for reduced secondary FP. The secondary FP rate at 12 months is acceptable in patients without risk factors. PMID- 30288593 TI - Real-Time US-18FDG-PET/CT Image Fusion for Guidance of Thermal Ablation of 18FDG PET-Positive Liver Metastases: The Added Value of Contrast Enhancement. AB - PURPOSE: To assess the feasibility of US-18FDG-PET/CT fusion-guided microwave ablation of liver metastases either poorly visible or totally undetectable with US, CEUS and CT, but visualized by PET imaging. MATERIALS AND METHODS: Twenty three patients with 58 liver metastases underwent microwave ablation guided by image fusion system that combines US with 18FDG-PET/CT images. In 28/58 tumors, 18FDG-PET/CT with contrast medium (PET/CECT) was used. The registration technical feasibility, registration time, rates of correct targeting, technical success at 24 h, final result at 1 year and complications were analyzed and compared between the PET/CT and PET/CECT groups. RESULTS: Registration was successfully performed in all cases with a mean time of 7.8 + 1.7 min (mean + standard deviation), (4.6 + 1.5 min for PET/CECT group versus 10.9 + 1.8 min for PET/CT group, P < 0.01). In total, 46/58 (79.3%) tumors were correctly targeted, while 3/28 (10.7%) and 9/30 (30%) were incorrectly targeted in PET/CT and PET/CECT group, respectively (P < 0.05). Complete ablation was obtained at 24 h in 70.0% of cases (n = 40 tumors), 23/28 (82.1%) in the PET/CECT group and 17/30 (56.7%) in the PET/CT group (P < 0.037). Fourteen tumors underwent local retreatment (11 ablations, 2 with resection and 1 with stereotactic body radiation therapy), while 4 tumors could not be retreated because of distant disease progression and underwent systemic therapy. Finally, 54/58 (93.1%) tumors were completely treated at 1 year. One major complication occurred, a gastrointestinal hemorrhage which required surgical repair. CONCLUSIONS: Percutaneous ablation of 18FDG-PET positive liver metastases using fusion imaging of real-time US and pre-acquired 18FDG-PET/CT images is feasible, safe and effective. Contrast-enhanced PET/CT improves overall ablation accuracy and shortens procedural duration time. PMID- 30288596 TI - Diagnosis and management of nocturia in current clinical practice: who are nocturia patients, and how do we treat them? AB - OBJECTIVE: To characterize the current evaluation, and efficacy of treatments in patients with the primary complaint of nocturia. METHODS: A retrospective chart review was performed of new patient encounters seen in a tertiary urology practice from May 2010 to September 2016 with the primary diagnosis of nocturia (ICD-9 788.43 and ICD-10 R35.1). RESULTS: 595 patients were identified. 403 met inclusion criteria. The median patient reported that nocturia episodes were 4 (1 20). 192 patients (48%) reported previous treatment for nocturia. After the index visit, a bladder diary (BD) was utilized in 50% of patients, with a 62% (n = 124) completion rate at follow-up visit. On BD analysis, the most common etiologies of nocturia were nocturnal polyuria 76% (n = 90) and overactive bladder in 21% (n = 26). Patient reported improvement with therapy after BD completion was 46% (n = 34), similar to patients without voiding diaries (43% improvement, n = 153). Anticholinergics and alpha blockers were the most commonly recommended drug, but no specific medication was associated with nocturia improvement. Oral desmopressin was used in 5% of patients. CONCLUSION: Nocturia is a common condition and very commonly patients have sought treatment prior to presentation. Bladder diaries were recommended to half of the patients. Patient reported that improvement did not seem to correlate with completion of a bladder diary. Though most patients had NP the use of desmopressin was very low. Current treatments used in managing nocturia may lack efficacy. PMID- 30288595 TI - Effect of temperature on the locomotor performance of species in a lizard assemblage in the Puna region of Argentina. AB - Locomotion is relevant to the ecology of reptiles because of its presumed influence on an organism's Darwinian fitness. Moreover, in ectothermic species, physiological performance capacity is affected by body temperature. We analyzed two components of locomotor performance in three species of lizards, Phymaturus extrilidus, Liolaemus parvus, and Liolaemus ruibali, in the Puna environment of Argentina. First, we estimated the thermal sensitivity of locomotion by measuring sprint speed at four different body temperatures. We included two measures of sprint speed: initial velocity and long sprint for sustained runs. Based on these data, we calculated the optimal temperature for performance and the optimal performance breadth. We also estimated endurance capacity at a single temperature. Maximum sprint speed for L. parvus was greater than L. ruibali and P. extrilidus in both initial velocity and long sprint. In contrast, L. parvus exhibited lower levels of endurance than L. ruibali and P. extrilidus. However, endurance in L. ruibali exceeded that of P. extrilidus. The species differed in the optimal temperature for the initial velocity with the lowest for L. ruibali (31.8 degrees C) followed by P. extrilidus (33.25 degrees C) and then L. parvus (36.25 degrees C). The optimal temperature for long sprint varied between 32 and 36 degrees C for all species. We found that all species attained maximum performance at body temperatures commonly experienced during daily activity, which was higher than the thermal quality of the environment. We found evidence for thermal sensitivity in locomotor performance in these species. However, we also show that the broad thermal breadth of performance suggests that the lizards are capable of sustaining near optimal levels of locomotor performance at ambient temperatures that would appear to be suboptimal. Thus, this lizard assemblage is capable of coping with the highly variable climatic conditions in the Puna region of Argentina. PMID- 30288594 TI - The neuropharmacology of sleep paralysis hallucinations: serotonin 2A activation and a novel therapeutic drug. AB - Sleep paralysis is a state of involuntary immobility occurring at sleep onset or offset, often accompanied by uncanny "ghost-like" hallucinations and extreme fear reactions. I provide here a neuropharmacological account for these hallucinatory experiences by evoking the role of the serotonin 2A receptor (5-HT2AR). Research has shown that 5-HT2AR activation can induce visual hallucinations, "mystical" subjective states, and out-of-body experiences (OBEs), and modulate fear circuits. Hallucinatory experiences triggered by serotonin-serotonergic ("pseudo") hallucinations, induced by hallucinogenic drugs-tend to be "dream like" with the experiencer having insight ("meta-awareness") that he is hallucinating, unlike dopaminergic ("psychotic" and "life-like") hallucinations where such insight is lost. Indeed, hallucinatory experiences during sleep paralysis have the classic features of serotonergic hallucinations, and are strikingly similar to perceptual and subjective states induced by hallucinogenic drugs (e.g., lysergic acid diethylamide [LSD] and psilocybin), i.e., they entail visual hallucinations, mystical experiences, OBEs, and extreme fear reactions. I propose a possible mechanism whereby serotonin could be functionally implicated in generating sleep paralysis hallucinations and fear reactions through 5-HT2AR activity. Moreover, I speculate on the role of 5-HT2C receptors vis-a-vis anxiety and panic during sleep paralysis, and the orbitofrontal cortex-rich with 5-HT2A receptors-in influencing visual pathways during sleep paralysis, and, in effect, hallucinations. Finally, I propose, for the first time, a drug to target sleep paralysis hallucinations and fear reactions, namely the selective 5-HT2AR inverse agonist, pimavanserin. This account implicates gene HTR2A on chromosome 13q as the underlying cause of sleep paralysis hallucinations and could be explored using positron emission tomography. PMID- 30288597 TI - Fiducial markers: can the urologist do better? AB - INTRODUCTION: Radiotherapy to the bladder has a risk of toxicity to pelvic structures, which can be reduced by using fiducial markers for targeting. Injectable contrast offers an alternative marker to gold seeds, which may fall out or exacerbate scarring. Combining contrast agents with tissue glue can minimize dispersion through tissue, enhancing its utility. We evaluated combinations of contrast agents and tissue glue using porcine bladder, for feasibility and utility as fiducial markers to aid image-guided radiotherapy. METHODS: Different contrast agents (Lipiodol ultra or Urografin) were combined with different tissue glues (Histoacryl, Tisseal or Glubran2). The mixtures were endoscopically injected into porcine bladder submucosa to identify the area of interest with multiple fiducial markers. The porcine bladders were imaged within a phantom porcine pelvis using standard radiation therapy imaging modalities. The feasibility as an injectable fiducial marker and visibility of each fiducial marker on imaging were scored as binary outcomes by two proceduralists and two radiation therapists, respectively. RESULTS: Lipiodol-glue combinations were successfully administered as multiple fiducials that were evident on CT and CBCT. Lipiodol with Histoacryl or Glubran2 was visible on kV imaging. The Lipiodol Glubran2 combination was deemed subjectively easiest to use at delivery, and a better fiducial on KV imaging. CONCLUSION: This study demonstrates the feasibility of mixing contrast medium Lipiodol with Histoacryl or Glubran2 tissue glue, which, injected endoscopically, provides discrete and visible fiducial markers to aid image-guided radiotherapy. Although promising, further study is required to assess the durability of these markers through a course of radiotherapy. PMID- 30288598 TI - Aquablation of the prostate: single-center results of a non-selected, consecutive patient cohort. AB - PURPOSE: Aquablation of the prostate using the AquaBeamTM system promises equivalent functional outcomes, reduced learning curve, and improved sexual function compared to transurethral prostate resection as shown in prospective randomized trials. This prospective cohort study aims to evaluate if published results can be transferred into the clinical routine in a non-selected patient collective. METHODS: This study includes all patients treated between September 2017 and June 2018 with Aquablation of the prostate. Patients have been evaluated prospectively for the perioperative course and early follow-up. Besides voiding parameter and symptom score, TRUS-volume change, ejaculatory function, and adverse events have been recorded. RESULTS: 118 consecutive patients have been treated in the given time. Aquablation could be carried out successfully in all patients. IPSS, QoL, Qmax, and PVR improved significantly after the procedure and continued to improve during 3-month follow-up. Mean OR time was 20 min, TRUS volume decreased by 65%, and 73% of the patients retained antegrade ejaculation. Thirteen adverse events (> Clavien-Dindo I) occurred in 10 patients. CONCLUSION: The surgical ablation of the prostate using Aquablation achieved significant and immediate improvement of functional voiding parameters Qmax and PVR as well as symptomatic improvement of IPSS and QoL. Aquablation seems to be safe and effective with a low perioperative complication profile even in a non-selected group of patients. PMID- 30288599 TI - Reference Intervals and Percentile Curves of Echocardiographic Left Ventricular Mass, Relative Wall Thickness and Ejection Fraction in Healthy Children and Adolescents. AB - Despite the clinical utility of echocardiography to measure cardiac target organ injury (TOI) there are scarcities of data about the reference intervals (RIs) and percentiles of left ventricular (LV) mass (LVM) and derived indexes (LVMI and LVMI2.7), relative wall thickness (LVRWT) and ejection fraction (LVEF) from population-based studies in children and adolescents. The aim of this study was to generate reference intervals RIs of LVM and derived indexes (LVMI and LVMI2.7), LVRWT, and LVEF obtained in healthy children, adolescents, and young adults from a South-American population. Echocardiographic studies were obtained in 1096 healthy subjects (5-24 years). Age and sex-specific RIs of LVM, LVMI, LVMI2.7, LVRWT, and LVEF were generated using parametric regression based on fractional polynomials. After covariate analysis (i.e., adjusting by age, body surface area) specific sex-specific RIs were evidenced as necessaries. Age and sex-specific 1st, 2.5th, 5th, 10th, 25th, 50th, 75th, 90th, 95th, 97.5th, and 99th percentile and curves were reported and compared with previously reported RIs. RIs showed high concordance and complementarity with what was previously reported for the population of North-American children (0-18 years old). In conclusion, in children and adolescents the interpretation of the LVM, LVMIs, LVRWT, and LVEF RIs requires sex-related RIs. This study provides the largest Argentinean database concerning RIs and percentile curves of LVM, LVMIs, LVRWT, and LVEF as markers of cardiac TOI obtained in healthy children and adolescents. These data are valuable in that they provide RIs values with which data of populations of children, adolescents can be compared. PMID- 30288600 TI - Respiratory Testing and Hospital Outcomes in Asymtomatic Infants Undergoing Heart Surgery. AB - Respiratory viral infections in infants undergoing congenital heart surgery lead to prolonged intubation time, hospital (HLOS) and cardiac intensive care unit length of stay (CICU LOS). The objective of this study was to evaluate the prevalence of respiratory viruses using molecular testing in otherwise healthy infants presenting for low complexity heart surgery, and to evaluate the impact of a positive viral screen and study questionnaire on post-surgical HLOS, CICU LOS, intubation time, respiratory complications, and oxygen therapy at home discharge. Sixty-nine infants (1 month to 1 year) undergoing cardiac surgery from November to May of the years 2012 to 2014 were prospectively enrolled, surveyed and tested. We compared the outcomes of positive molecular testing and positive study questionnaire to test negative subjects. We also evaluated the predictive value of study questionnaire in identification of viruses by molecular testing. Of the 69 enrolled infants, 58 had complete information available for analysis. 17 (30%) infants tested positive by molecular testing for respiratory pathogens. 38 (65%) had a "positive" questionnaire. Among the 20 viruses detected, Human Rhinovirus was the most common 12 (60%). Seven (12%) of the 58 patients developed respiratory symptoms following surgery prompting molecular testing. Four of these tested positive for a respiratory virus post-surgically. Neither positive molecular testing nor a positive questionnaire prior to surgery was associated with greater post-operative HLOS, CICU LOS, intubation time, respiratory complications, or use of oxygen at discharge compared to negative testing. The questionnaire poorly predicted positive molecular testing. Routine screening for respiratory viruses in asymptomatic infants may not be an effective strategy to predict infants at risk of post-operative complications.

AB - Endoscopic negative-pressure therapy (ENPT) is becoming a valuable tool in surgical complication management of transmural intestinal defects and wounds in the upper and lower gastrointestinal tract. Innovative materials for drains have been developed, endoscopic techniques adapted, and new indications for ENPT have been found. Based on our broad clinical experience, numerous tips and tricks are described, which contribute to the safety of dealing with the new therapy. The aim of this work is to present these methods. The focus is on describing the treatment in the esophagus. PMID- 30288602 TI - Exercise improves functional capacity and lean body mass in patients with gastrointestinal cancer during chemotherapy: a single-blind RCT. AB - PURPOSE: Although growing evidence underlines the benefits of physical activity as supportive intervention for cancer patients, sparse data are available for exercise in patients with advanced disease stages, in particular for gastrointestinal cancer (GIC) patients who experience specific disease-associated limitations. Thus, the aim of this study is to evaluate the effects of home-based moderate intensity exercise on functional capacity, activities of daily living (ADL) and body composition in patients with advanced GIC during first-line chemotherapy. METHODS: Participants (GIC, UICC III-IV; n = 44) were randomly assigned to home-based physical activity programme of 150 min moderate walking per week or a control group (CG). Functional status (SPPB: gait speed, balance, lower extremity muscle strength), postural sway, chemotherapy-induced peripheral neuropathy, nutritional state (Mini Nutritional Assessment, MNA) and lean body mass were assessed according to established recommendations. All tests were performed before chemotherapy (T0), after two chemotherapy cycles (T1) and after 12 weeks (T2). RESULTS: SPPB changes from T1 to T2 differed between groups with a comparably greater decrease in the CG (p < .05), but no changes or group differences over the whole study period (T0 to T2) were found. Exercise improved postural sway (T0 to T1; T0 toT2) and lean body mass (T1 to T2; T0 to T2) compared to the control group (p < .05). Gait speed, peripheral neuropathy and strength did not differ between groups (p > .05). CONCLUSIONS: Our results indicate that a home-based physical activity improves postural sway and body composition and might stabilize functional capacity in patients with advanced GIC during chemotherapy. Although the other outcomes did not differ between groups, aforementioned effects might contribute to a maintenance of independency in ADL and a better treatment tolerance and thus enhance patients' quality of life. PMID- 30288603 TI - A conformationally restricted GABA analogue based on octahydro-1H cyclopenta[b]pyridine scaffold. AB - An approach to rel-(4aS,6R,7aR)-octahydro-1H-cyclopenta[b]pyridine-6-carboxylic acid-a bicyclic conformationally restricted gamma-aminobutyric acid (GABA) analogue was developed. The eight-step sequence relied on the reaction of 2,3 bis(chloromethyl)pyridine and a C1-binucleophile and the catalytic reduction of the pyridine ring as the key steps and allowed for the preparation of the title compound in 9.0% overall yield.

AB - Consecutive multicomponent reactions have been applied for the synthesis of novel pseudo-peptides bearing dithiocarbamate and N,X-heterocyclic groups (X = S, O) in only one structure. The first multicomponent reaction includes the synthesis of dithiocarbamates using an amine or amino acid, CS2 and an electrophile. The second MCR is synthesis of Asinger imines using 2-chloroisobutyraldehyde, NaXH (X = S, O), ketone and ammonia. The final MCR is Ugi reaction to afford the corresponding three-dimensional pseudo-peptides. Various Asinger imines, carboxylic acids and isocyanides were applied in this protocol to provide diversities of pseudo-peptides in high to excellent yields.

AB - PURPOSE: Harvesting bone from the ascending ramus of the mandible is a common procedure. However, mandibular fracture may occur after grafting bone blocks. This study aimed to investigate the resulting force distribution of stress and strain in the mandibular donor site after harvesting bone grafts of different sizes and various loadings. METHODS: Finite element analysis was performed for virtual harvesting of bone blocks of nine different sizes between 15 * 20 and 25 * 30 mm and three different chewing loads (incisal, ipsilateral and contralateral). von Mises stress and first principal stress distributions were measured. RESULTS: von Mises stress was distributed between 35.01 (10 * 15 mm graft, incisal load) and 333.25 MPa (30 * 20 mm graft ipsilateral load), whereas first principal stress distributions were between 48.27 (10 * 15 mm graft, incisal load) and 414.69 MPa (30 * 20 mm graft ipsilateral load). In general, the least stress was observed with incisal load followed by ipsilateral load and finally contralateral load. The critical value of 133 MPa was found after removing almost all grafts with a width of 20 or 30 mm. CONCLUSIONS: Incisal loading led to less stress compared with contralateral and ipsilateral loads. Increasing graft size led to increasing weakness of the donor site. Graft width exerted a greater influence on stress development than its height. CLINICAL RELEVANCE: Ipsilateral chewing and increasing width of the bone graft result in maximum stress in the mandibular donor side, and critical values regarding to the possibility of fractures are already to expect from a graft size of 20 * 15 mm. PMID- 30288606 TI - Distances of root apices to adjacent anatomical structures in the anterior maxilla: an analysis using cone beam computed tomography. AB - OBJECTIVES: The aim was to assess the anatomical relationship of anterior maxillary teeth to the nasal floor in patients referred for apical surgery. MATERIALS AND METHODS: Cone beam computed tomographic images (CBCT) of 83 patients were analysed retrospectively to quantify the distances between the root apices of maxillary anterior teeth (canine to canine) to the nasal floor or maxillary sinus (whichever was closer). Secondary outcome variables were the distances of the periapical lesion to the nasal floor, distances of the apices to the labial and palatal bone plates as well as to the neighbouring teeth. RESULTS: A total of 93 teeth (39 central, 35 lateral incisors and 19 canines) were analysed. The mean shortest distances of the apices to the nasal floor (or maxillary sinus) were 8.54 mm for central incisors, 9.49 mm for lateral incisors and 5.39 mm for the canines. The canines exhibited a significantly shorter distance to the nasal floor/maxillary sinus. In the presence of an osteolysis, the distance to the nasal floor was significantly shorter compared to the teeth without lesions. The lateral and central incisors showed significant proximity to each other at the level of the future surgical resection (3 mm from the apex). CONCLUSIONS: A close proximity between apices and adjacent anatomical structures such as nasal floor, maxillary sinus or adjacent roots could be shown in some cases. CLINICAL RELEVANCE: CBCT could be a valuable adjunctive imaging tool prior to apical surgery in the anterior maxilla to assess the risk for and decrease the incidence of damage to neighbouring anatomical structures such as the nasal floor, maxillary sinus or adjacent roots.

AB - An orthotospovirus distinct from all other orthotospoviruses was isolated from naturally infected alstroemeria plants. Disease symptoms caused by this virus mainly consisted of yellow spots on the leaves based on which the name alstroemeria yellow spot virus (AYSV) was coined. A host range analysis was performed and a polyclonal antiserum was produced against purified AYSV ribonucleoproteins which only reacted with the homologous antigen and not with any other (established or tentative) orthotospovirus from a selection of American and Asian species. Upon thrips transmission assays the virus was successfully transmitted by a population of Thrips tabaci. The entire nucleotide sequence of the M and S RNA segments was elucidated by a conventional cloning and sequencing strategy, and contained 4797 respectively 2734 nucleotides (nt). Simultaneously, a next generation sequencing (NGS) approach (RNAseq) was employed and generated contigs covering the entire viral tripartite RNA genome. In addition to the M and S RNA nucleotide sequences, the L RNA (8865 nt) was obtained. The nucleocapsid (N) gene encoded by the S RNA of this virus consisted of 819 nucleotides with a deduced N protein of 272 amino acids and by comparative sequence alignments to other established orthotospovirus species showed highest homology (69.5% identity) to the N protein of polygonum ringspot virus. The data altogether support the proposal of AYSV as a new orthotospovirus species within a growing clade of orthotospoviruses that seem to share the Middle East basin as a region of origin.

PMID- 30288608 TI - Nitrogen enrichment in host plants increases the mortality of common Lepidoptera species. AB - The recent decline of Lepidoptera species strongly correlates with the increasing intensification of agriculture in Western and Central Europe. However, the effects of changed host-plant quality through agricultural fertilization on this insect group remain largely unexplored. For this reason, we tested the response of six common butterfly and moth species to host-plant fertilization using fertilizer quantities usually applied in agriculture. The larvae of the study species Coenonympha pamphilus, Lycaena phlaeas, Lycaena tityrus, Pararge aegeria, Rivula sericealis and Timandra comae were distributed according to a split-brood design to three host-plant treatments comprising one control treatment without fertilization and two fertilization treatments with an input of 150 and 300 kg N ha-1 year-1, respectively. In L. tityrus, we used two additional fertilization treatments with an input of 30 and 90 kg N ha-1 year-1, respectively. Fertilization increased the nitrogen concentration of both host-plant species, Rumex acetosella and Poa pratensis, and decreased the survival of larvae in all six Lepidoptera species by at least one-third, without clear differences between sorrel- and grass-feeding species. The declining survival rate in all species contradicts the well-accepted nitrogen-limitation hypothesis, which predicts a positive response in species performance to dietary nitrogen content. In contrast, this study presents the first evidence that current fertilization quantities in agriculture exceed the physiological tolerance of common Lepidoptera species. Our results suggest that (1) the negative effect of plant fertilization on Lepidoptera has previously been underestimated and (2) that it contributes to the range-wide decline of Lepidoptera. PMID- 30288610 TI - Impact of a prenatal episode and diagnosis in women with serious mental illnesses on neonatal complications (prematurity, low birth weight, and hospitalization in neonatal intensive care units). AB - Pregnancy in women with mental disorders is increasingly common. The aim of this study was to determine, in women with severe mental illnesses, whether a prenatal episode was related to neonatal complications and if a specific disorder was associated with a higher risk. A population of infants and their mothers (n = 1439) jointly admitted to psychiatric Mother-Baby Units in France and Belgium (2001-2010) was assessed respectively for prematurity, low birth weight (LBW), hospitalization in neonatal intensive care units (NICUs), and maternal mental health during pregnancy. Logistic regression was used to explore the association between neonatal complications and a prenatal episode of mental illness and if the presence of a specific disorder was related to a higher risk, taking into account maternal socio-demographic characteristics, pregnancy data, and antenatal exposure to psychotropic drugs. Among the children, 145 (10.2%) were premature, 226 (15.8%) had a LBW, and 348 (24.3%) have been hospitalized in neonatology. The presence of an episode of mental illness during pregnancy was linked to LBW (OR = 2.21 [1.44-3.38]; p = 0.003) and NICU hospitalizations (OR = 1.53 [1.06-2.19], p = 0.002). Among diagnoses, the presence of a severe substance use disorder in these women was related to LBW (OR = 2.96 [1.49-5.85]; p = 0.002) and NICU (OR = 2.88 [1.56-5.29]; p = 0.04). Our results underline the importance of systematic and early detection of psychiatric symptoms and substance use disorders during pregnancy in preventing neonatal complications in women with serious mental illness. PMID- 30288611 TI - In situ assessment of mitochondrial calcium transport in tobacco pollen tubes. AB - Pollen tubes require functional mitochondria in order to achieve fast and sustained growth. In addition, cell wall expansion requires a calcium gradient in the tube apex formed by a dedicated array of calcium pumps and channels. Most studies have traditionally focused on the molecular aspects of calcium interactions and transport across the pollen tube plasmalemma. However, calcium transients across mitochondrial membranes from pollen tubes are beginning to be studied. Here, we report the presence of a ruthenium red-sensitive mitochondrial calcium uniporter-like activity in tobacco pollen tubes with functional oxidative phosphorylation. The present study provides a framework to measure in situ specifics of mitochondrial transport and respiration in pollen tubes from different plants. The relevance of a mitochondrial calcium uniporter for pollen tube growth is discussed.

PMID- 30288614 TI - Investigating the effect of climatic parameters on mental disorder admissions. AB - The main objective of this study was to evaluate the role of climatic parameters and phenomena including the monthly number of dusty/rainy/snowy/foggy days, cloudiness (Okta), horizontal visibility, and barometric pressure (millibar) on major depressive disorder, bipolar, schizophrenia, and schizoaffective admissions. The monthly data related to the number of admissions in Farshchian hospital and climatic parameters from March 2005 to March 2017 were extracted. Random forest regression and dynamic negative binomial regression were used to examine the relationship between variables; the statistical significance was considered as 0.05. The number of dusty/rainy/snowy/foggy days, cloudiness, and the number of days with vision less than 2 km had a significant positive relationship with admissions due to schizophrenia (p < 0.05). Barometric pressure had a negative effect on schizophrenia admissions (p < 0.001). The number of dusty/rainy/snowy/foggy days and cloudiness had a significant effect on schizoaffective admissions (p < 0.05). Bipolar admissions were negatively associated with rainy days and positively associated with dusty days and cloudiness (p < 0.05). The number of rainy/dusty/snowy days and cloudiness had a positive significant effect on major depressive disorder admissions. The results of the present study confirmed the importance of climatic parameter variability for major depressive disorder, bipolar, schizophrenia, and schizoaffective admissions. PMID- 30288615 TI - Colorimetric determination of dopamine by exploiting the enhanced oxidase mimicking activity of hierarchical NiCo2S4-rGO composites. AB - A composite consisting of NiCo2S4 and reduced graphene oxide (rGO) was prepared via a hydrothermal process. Compared to individual NiCo2S4 nanomaterials or reduced graphene oxide, the composite exhibits enhanced oxidase-like activity. It is found that dopamine (DA) inhibits the ability of NiCo2S4-rGO to oxidize the substrate 3,3',5',5'-tetramethylbenzidine (TMB) to form blue colored ox-TMB. Based on these findings, a colorimetric method for determination of DA was worked out. The absorption, best measured at 652 nm, increases linearly in the 0.5-100 MUM DA concentration range, and the limit of detection is 0.42 MUM. This method was successfully applied to the detection of DA in spiked human serum samples. Graphical abstract A hierarchical NiCo2S4-rGO composite was prepared through two step hydrothermal process. It exhibits enhanced oxidase-like activity which, however, is inhibited by dopamine (DA). Hence, less blue colored ox-TMB is formed by oxidation of 3,3',5,5'-tetramethylbenzidine in the presence of dopamine. PMID- 30288616 TI - Medical Image Quality Assessment Using CSO Based Deep Neural Network. AB - This manuscript proposed a hybrid method of Deep Neural Network (DNN) and Cuckoo Search Optimization (CSO) with No-Reference Image Quality Assessment (NR-IQA) for achieving high accuracy, low computational complexity, flexibility and etc. of a medical image. NR-IQA is proposed due to till now there is no perfect reference image for finding the quality of real time medical imaging. It is an effective method for assessing the real-world medical images. The proposed method takes the distorted image as an input and estimate the quality of the image without the assistance of reference image. The techniques CSO and DNN with NR-IQA produces the quality of the image with high quality score and low Mean Square Error (MSE). Also, the proposed method is used to improve the quality score thereby improving the quality of the image. So that the resultant image has good visual properties which is useful for the analysis of further medical proceedings. The simulation result shows that the proposed system improves the quality score by 8% when compared to the other existing systems. The SROCC value can be increased as 6%, 14%, 6 and 2% for the different existing methods such as NR-BIQA, SBVQP-ML, PTQL/PTVC and NR-SIQA (3D) respectively. PMID- 30288617 TI - Long-term outcomes after prophylactic use of onlay mesh in midline laparotomy. AB - BACKGROUND: The prevalence of incisional hernias (IHs) is still high after midline laparotomy (ML). There is an increasing body of evidence that prophylactic mesh placement (PMP) can be safe and efficient in the short-term outcomes, but there still are some concerns about the potential long-term complications of these meshes. This study describes our long-term PMP experience. METHODS: Observational and prospective study including all patients undergoing the use of prophylactic onlay large-pore polypropylene meshes for the closure of ML since 2008 to 2014. Outcome measures included demographics, perioperative details, wound complications, recurrences, reoperations and chronic complications. RESULTS: A cohort of 172 patients was analysed: 75% elective surgery, 25% emergency cases. Mean age was 68 years with mean body mass index (BMI) of 28.6 kg/m2. Wound classification: 6.4% clean; 85% clean-contaminated; 1.2% contaminated and 8.1% dirty. Follow-up of patients was up to 8 years (mean: 5 +/- 1.6). Two meshes were removed due to chronic infection in first six postoperative months. Of the 13 patients (9.02%) who developed IH, 5 of them have been reoperated for IH repair without any difficulty related to previous mesh. During follow-up, 8 patients have been reoperated for other reasons and the integrity of abdominal wall was also checked. After the comparative study, higher BMI and emergency surgery were still risk factors for IH despite PMP. CONCLUSIONS: In our setting, the use of polypropylene prophylactic meshes in MLs is safe, efficient and durable.

AB - To address the growing challenges from drug-resistant microbes and tumor incidence, approaches are being undertaken to phytosynthesize metal nanoparticles, particularly silver nanoparticles, to get remedial measure. In this study, an attempt has been made to utilize a major biowaste product, pomegranate fruit peel (Punica granatum), to synthesize silver nanoparticles. The silver nanoparticles (AgNPs) were synthesized using the aqueous extract of pomegranate peel. The formation of synthesized AgNPs was confirmed through UV-Vis spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX) as well as through the change of the colorless aqueous solution to a dark brown solution. Using UV-Vis spectroscopy, the dark brown solution showed a Plasmon resonance band peak at 378 nm in UV-Vis spectroscopy after reacting for 24, 48, and 72 h. The XRD report revealed that the AgNPs had a cubic structure. The TEM and SEM report showed the nanoparticles were equally distributed in the solution, with a spherical shape and size ranging from 20 to 40 nm and with an average particle size of 26.95 nm. EDX imaging also confirmed the presence of AgNPs. The synthesized AgNPs were found to exhibit good antimicrobial effects on Gram-negative and Gram-positive bacteria, particularly the pathogens Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27584), Proteus vulgaris (ATCC 8427), Salmonella typhi (ATCC 14028), Staphylococcus aureus (ATCC 29213), Staphylococcus epidermidis (MTCC 3615), and Klebsiella pneumonia. The cytotoxic effects of AgNPs were also tested against a colon cancer cell line (RKO: ATCC(r) CRL-2577TM), and it was observed that the viabilities were 56% and 61% on days 3 and 5, respectively, with exposure to 12.5 MUg of AgNPs. This simple, economic, and eco-friendly method suggests that the AgNPs biosynthesized using pomegranate peel extract may be a novel, potent solution for the development of a drug for colon cancer that also has antibacterial activity. PMID- 30288619 TI - Efficient Trilayer Phosphorescent Organic Light-Emitting Devices Without Electrode Modification Layer and Its Working Mechanism. AB - At present, numerous functional layers are introduced to improve the carrier injection and balance the carrier transport in organic light-emitting devices (OLEDs). Although it may be a good way to enhance the efficiency of devices, the introduction of functional layers would also result in extra process and long manufacture period. Actually, with the enrichment of material system, many appropriate materials could be chosen to share two or even more functions in OLEDs. Here, via impedance spectroscopy and transient electroluminescence analysis, di-[4-(N,N-ditolyl-amino)-phenyl] cyclohexane (TAPC) and 4,7-diphenyl 1,10-phenanthroline (Bphen) are demonstrated to serve as carrier injection and transport layers simultaneously. As a result, efficient trilayer OLEDs are achieved with comparable performances to conventional multilayer devices. Further studies have also been carried out to analyze the recombination and quenching mechanisms in devices. TAPC can block electrons effectively, while Bphen avoids the accumulation of holes. It makes carriers in emitting layer become more balanced, resulting in the reduction of efficiency roll-off. PMID- 30288620 TI - Seed-Mediated Synthesis of Tunable-Aspect-Ratio Gold Nanorods for Near-Infrared Photoacoustic Imaging. AB - Tunable-aspect ratio gold nanorods have been synthesized by a modified seed mediated synthesis method. Ascorbic acid was employed as a shape controller to induce anisotropic growth, which made the aspect ratio of the synthesized gold nanorods range from 8.5 to 15.6. These nanorods possess tunable longitudinal surface plasmon resonance absorption band, covering a broad near-infrared (NIR) range, from ~ 680 to 1100 nm. When modified with thiol-polyethylene glycol (SH PEG), the synthesized Au nanorods showed excellent biocompatibility and stability, which foreshadowed the great potential of their NIR application as photoacoustic contrast agent. Due to their adjustable absorbance in the NIR, the synthesized Au nanorods could offer stronger contrast (3.1 times to the control group without contrast agent used) and higher signal-noise ratio values (SNR; 5.6 times to the control group) in photoacoustic imaging, both in vitro and in vivo experiments. Our work presented here not only added some novel Au-based photoacoustic contrast agents but also described a possibility of contrast agent preparation covering the whole biological NIR window. PMID- 30288621 TI - Necrotizing fasciitis as a complication of osteonecrosis of the jaw related to oral bisphosphonate application in a patient with osteoporosis: a case report. AB - BACKGROUND: Necrotizing fasciitis has been reported as a complication secondary to bisphosphonate-related osteonecrosis of the jaw (BRONJ) in a low number of patients. The only report of such a case in an osteoporosis patient found in current literature was related to short-term bisphosphonate but long time corticosteroid and methotrexate treatment. CASE PRESENTATION: In this article, we report a case of necrotizing fasciitis secondary to osteonecrosis of the jaw related to long-term oral bisphosphonate treatment in an osteoporosis patient additionally suffering from poorly controlled type 2 diabetes. Diabetes mellitus not only has been reported to be a systemic risk factor regarding BRONJ but also to be the most common comorbidity in patients presenting with necrotizing fasciitis and to increase mortality of this condition. Necrotizing fasciitis and BRONJ in the patient could eventually be resolved by a surgical approach and intravenous antibiotic therapy. CONCLUSIONS: The case presented suggests diabetes mellitus potentially having been an important factor in the particularly unfavorable course of therapy. It emphasizes the importance of an adequate therapy and surveillance of modifiable systemic risk factors like diabetes mellitus in patients being at risk for development of BRONJ. If necrotizing fasciitis is suspected, early diagnosis and aggressive surgical and medical management are essential to minimize morbidity and mortality. PMID- 30288622 TI - In-situ electrochemical analysis of microbial activity. AB - Microbes have a wide range of metabolic capabilities available that makes them industrially useful organisms. Monitoring these metabolic processes is a crucial component in efficient industrial application. Unfortunately, monitoring these metabolic processes can often be invasive and time consuming and expensive, especially within an anaerobic environment. Electrochemical techniques, such as cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) offer a non-invasive approach to monitor microbial activity and growth. EIS and CV were used to monitor Clostridium phytofermentans, an anaerobic and endospore-forming bacterium. C. phytofermentans ferments a wide range of sugars into hydrogen, acetate, and ethanol as fermentation by-products. For this study, both traditional microbiological and electrochemical techniques were used to monitor the growth of C. phytofermentans and the formation of fermentation products. An irreversible reduction peak was observed using CV beginning at mid-logarithmic phase of growth. This peak was associated with C. phytofermentans and not the spent medium and was indicative of a decrease in carbon and energy sources to the cells. Additionally, EIS analysis during growth provided information related to increased charge transfer resistance of the culture also as a function of carbon and energy source depletion. Results demonstrate that CV and EIS are useful tools in the monitoring the physiological status of bioprocesses. PMID- 30288623 TI - Rheumatology in and from Slovenia. PMID- 30288624 TI - Assessment of groundwater nitrate contamination hazard in a semi-arid region by using integrated parametric IPNOA and data-driven logistic regression models. AB - Groundwater hazard assessments involve many activities dealing with the impacts of pollution on groundwater, such as human health studies and environment modelling. Nitrate contamination is considered a hazard to human health, environment and ecosystem. In groundwater management, the hazard should be assessed before any action can be taken, particularly for groundwater pollution and water quality. Thus, pollution due to the presence of nitrate poses considerable hazard to drinking water, and excessive nutrient loads deteriorate the ecosystem. The parametric IPNOA model is one of the well-known methods used for evaluating nitrate content. However, it cannot predict the effect of soil and land use/land cover (LULC) types on calculations relying on parametric well samples. Therefore, in this study, the parametric model was trained and integrated with the multivariate data-driven model with different levels of information to assess groundwater nitrate contamination in Saladin, Iraq. The IPNOA model was developed with 185 different well samples and contributing parameters. Then, the IPNOA model was integrated with the logistic regression (LR) model to predict the nitrate contamination levels. Geographic information system techniques were also used to assess the spatial prediction of nitrate contamination. High-resolution SPOT-5 satellite images with 5 m spatial resolution were processed by object-based image analysis and support vector machine algorithm to extract LULC. Mapping of potential areas of nitrate contamination was examined using receiver operating characteristic assessment. Results indicated that the optimised LR-IPNOA model was more accurate in determining and analysing the nitrate hazard concentration than the standalone IPNOA model. This method can be easily replicated in other areas that have similar climatic condition. Therefore, stakeholders in planning and environmental decision makers could benefit immensely from the proposed method of this research, which can be potentially used for a sustainable management of urban, industrialised and agricultural sectors. PMID- 30288626 TI - Life beyond the Tanimoto coefficient: similarity measures for interaction fingerprints. AB - BACKGROUND: Interaction fingerprints (IFP) have been repeatedly shown to be valuable tools in virtual screening to identify novel hit compounds that can subsequently be optimized to drug candidates. As a complementary method to ligand docking, IFPs can be applied to quantify the similarity of predicted binding poses to a reference binding pose. For this purpose, a large number of similarity metrics can be applied, and various parameters of the IFPs themselves can be customized. In a large-scale comparison, we have assessed the effect of similarity metrics and IFP configurations to a number of virtual screening scenarios with ten different protein targets and thousands of molecules. Particularly, the effect of considering general interaction definitions (such as Any Contact, Backbone Interaction and Sidechain Interaction), the effect of filtering methods and the different groups of similarity metrics were studied. RESULTS: The performances were primarily compared based on AUC values, but we have also used the original similarity data for the comparison of similarity metrics with several statistical tests and the novel, robust sum of ranking differences (SRD) algorithm. With SRD, we can evaluate the consistency (or concordance) of the various similarity metrics to an ideal reference metric, which is provided by data fusion from the existing metrics. Different aspects of IFP configurations and similarity metrics were examined based on SRD values with analysis of variance (ANOVA) tests. CONCLUSION: A general approach is provided that can be applied for the reliable interpretation and usage of similarity measures with interaction fingerprints. Metrics that are viable alternatives to the commonly used Tanimoto coefficient were identified based on a comparison with an ideal reference metric (consensus). A careful selection of the applied bits (interaction definitions) and IFP filtering rules can improve the results of virtual screening (in terms of their agreement with the consensus metric). The open-source Python package FPKit was introduced for the similarity calculations and IFP filtering; it is available at: https://github.com/davidbajusz/fpkit .

AB - Nitrogen-doped microporous carbon spheres (NMCSs) are successfully prepared via carbonization and KOH activation of phenol-formaldehyde resin polymer spheres synthesized by a facile and time-saving one-step hydrothermal strategy using triblock copolymer Pluronic F108 as a soft template under the Stober-like method condition. The influence of the ethanol/water volume ratios and carbonation temperatures on the morphologies, pore structures and electrochemical performances of the prepared NMCSs are investigated systematically. The optimal NMCSs have a large specific surface area of 1517 m2 g- 1 with a pore volume of 0.8 cm3 g- 1. The X-ray photo-electron spectroscopy analysis reveals a suitable nitrogen-doped content of 2.6 at.%. The as-prepared NMCSs used as supercapacitor electrode materials exhibit an outstanding specific capacitance of 416 F g- 1 at a current density of 0.2 A g- 1, also it shows an excellent charge/discharge cycling stability with 96.9% capacitance retention after 10,000 cycles. The constructed symmetric supercapacitors using PVA/KOH as the gel electrolyte can deliver a specific capacitance of 60.6 F g- 1 at current density of 1 A g- 1. A maximum energy density of 21.5 Wh kg- 1 can be achieved at a power density of 800 W kg- 1, and the energy density still maintains 13.3 Wh kg- 1 even at a high power density of 16 kW kg- 1. The results suggest that this work can open up a facile and effective way to synthesize the NMCSs for electrode materials of high performance energy storage devices. PMID- 30288627 TI - Graphene-Based Nanoscale Vacuum Channel Transistor. AB - We report the fabrication and electrical performance of nanoscale vacuum channel transistor (NVCT) based on graphene. Ninety-nanometer-width vacuum nano-channel could be precisely fabricated with standard electron beam lithography process. The optimization and treatment of surface damage and adhesive residue on graphene are carried out by ultrasonic cleaning and thermal annealing. Additionally, in situ electric characteristics are directly performed inside a vacuum chamber of scanning electron microscope (SEM) with the nanomanipulator. By modulating the gate voltage, the NVCT could be switched from off-state to on-state, exhibiting an on/off current ratio up to 102 with low working voltages (< 20 V) and leakage current (< 0.5 nA). Furthermore, the nanoscale vacuum channel could enable to scale down the size of vacuum devices with high integration, making NVCT a promising candidate for high speed applications.

AB - Highly uniformed decorations of Cu2O nanoparticles on the sidewalls of silicon nanowires (SiNWs) with high aspect ratio were prepared through a two-step electroless deposition at room temperature. Morphology evolutions and photocatalytic performance of SiNWs decorated with aggregated and dispersed Cu2O nanoparticles were unveiled, and the correlated photodegradation kinetics was identified. In comparison with the conventional direct loadings where the aggregated Cu2O/SiNW structures were created, the uniform incorporation of Cu2O with SiNWs exhibited more than three and nine times of improved photodegradation efficiency than the aggregated-Cu2O/SiNWs and sole SiNWs, respectively.

AB - BACKGROUND: Hemorrhoidal prolapse is a common benign disease. The introduction of circular-stapled hemorrhoidopexy as an alternative to the conventional hemorrhoidectomy led to a new spectrum of postoperative outcomes and complications. The aim of the present study was to evaluate long-term results after stapled hemorrhoidopexy. METHODS: All the patients who had stapled hemorrhoidopexy using a PPH03 stapler, from January 2003 to December 2005, were retrospectively collected in a dedicated database. Between March and May 2016, all the patients were asked by phone to complete a questionnaire. The study evaluated anatomical recurrence, symptom recurrence and frequency, and satisfaction after surgery. The postoperative complications recorded were hemorrhage, hematoma, urinary retention, anastomotic stenosis, persistent anal pain, tenesmus, and impaired anal continence evaluated also with the Faecal Incontinence Severity Index score. RESULTS: One hundred and ninety four patients were identified and 171 completed the questionnaire. The mean follow-up was 12 +/ 0.8 years (range 11-13 years). Anatomical self-reported prolapse recurrence was 40.9% (n = 70). In 75.6% (n = 129) of patients, the severity and frequency of symptoms improved. The overall complication rate was 56.7% (n = 40) with a serious adverse event rate of 8.7% (n = 15). The overall tenesmus rate was 38.2% (n = 65) and the overall impaired continence rate was 39.1% (n = 67). Medical therapy was still required occasionally by 40.3% (n = 69) of the patients and 9.3% (n = 16) of the patients underwent surgery for recurrence. Patient satisfaction rate was good (>= 3 on a scale of 1 to 5) in 81.2% (n = 139) of cases. CONCLUSIONS: The study showed that stapled hemorrhoidopexy using the first generation devices is safe and feasible but associated with a high recurrence and incontinence rate. More stringent selection criteria in association with the use of large volume devices can lead to better results in the future. PMID- 30288632 TI - The biology of ageing and the omics revolution.

In this study, we reported the molecular cloning, tissue expression, and pharmacological characterization of Megalobrama amblycephala MC5R (MamMC5R), as well as the effect of catching stress on its expression. The full-length cDNA of Mammc5r gene was 1237 bp, consisted of a 990-bp open reading frame encoding 329 amino acids. Sequence analyses revealed that the nucleotide and amino acid sequences of Mammc5r were highly homologous (> 90%) with MC5Rs of zebrafish, common carp, and goldfish. Tissue expression profile analysis showed that Mammc5r was widely expressed in both central and peripheral tissues, with the highest expression in the brain. Catching stress significantly changed the expression of Mammc5r in the skin, brain, and eye. In the skin, the expression level of Mammc5r was significantly reduced at 1 h and 4 h and increased at 24 h after catching stress. The Mammc5r expression level was rapidly upregulated in the brain and eye at 1 h and then decreased to the level before stress at 4 h and 24 h. With human MC5R (HsaMC5R) as a control, several agonists including alpha-melanocyte stimulating hormone (alpha-MSH), and beta-MSH in addition to an analogue [Nle4, D Phe7]-alpha-MSH (NDP-MSH), were used to investigate the binding and signaling properties of MamMC5R. The results revealed that MamMC5R had the highest affinity for NDP-MSH, followed by alpha- and beta-MSH. Taken together, the data suggested that MamMC5R might play a role in stress response in M. amblycephala.

AB - In Parkinson's disease and other Lewy body disorders, the propagation of pathology has been accredited to the spreading of extracellular alpha-synuclein (alpha-syn). Although the pathogenic mechanisms are not fully understood, cell-to cell transfer of alpha-syn via exosomes and other extracellular vesicles (EVs) has been reported. Here, we investigated whether altered molecular properties of alpha-syn can influence the distribution and secretion of alpha-syn in human neuroblastoma cells. Different alpha-syn variants, including alpha-syn:hemi-Venus and disease-causing mutants, were overexpressed and EVs were isolated from the conditioned medium. Of the secreted alpha-syn, 0.1-2% was associated with vesicles. The major part of EV alpha-syn was attached to the outer membrane of vesicles, whereas a smaller fraction was found in their lumen. For alpha-syn expressed with N-terminal hemi-Venus, the relative levels associated with EVs were higher than for WT alpha-syn. Moreover, such EV-associated alpha-syn:hemi Venus species were internalized in recipient cells to a higher degree than the corresponding free-floating forms. Among the disease-causing mutants, A53T alpha syn displayed an increased association with EVs. Taken together, our data suggest that alpha-syn species with presumably lost physiological functions or altered aggregation properties may shift the cellular processing towards vesicular secretion. Our findings thus lend further support to the tenet that EVs can mediate spreading of harmful alpha-syn species and thereby contribute to the pathology in alpha-synucleinopathies.

AB - Our objective was to determine the relationship of T1rho and T2 relaxation mapping to the biochemical and biomechanical properties of articular cartilage through selective digestion of proteoglycans and collagens. Femoral condyles were harvested from porcine knee joints and treated with either chondroitinase ABC (cABC) followed by collagenase, or collagenase followed by cABC. Magnetic resonance images were acquired and cartilage explants were harvested for biochemical, biomechanical, and histological analyses before and after each digestion. Targeted enzymatic digestion of proteoglycans with cABC resulted in elevated T1rho relaxation times and decreased sulfated glycosaminoglycan content without affecting T2 relaxation times. In contrast, extractable collagen and T2 relaxation times were increased by collagenase digestion; however, neither was altered by cABC digestion. Aggregate modulus decreased with digestion of both components. Overall, we found that targeted digestion of proteoglycans and collagens had varying effects on biochemical, biomechanical, and imaging properties. T2 relaxation times were altered with changes in extractable collagen, but not changes in proteoglycan. However, T1rho relaxation times were altered with proteoglycan loss, which may also coincide with collagen disruption. Since it is unclear which matrix components are disrupted first in osteoarthritis, both markers may be important for tracking disease progression.

AB - Acute lung injury (ALI), developing as a component of the systemic inflammatory response syndrome (SIRS), leads to significant morbidity and mortality. Reactive oxygen species (ROS), produced in part by the neutrophil NADPH oxidase 2 (Nox2), have been implicated in the pathogenesis of ALI. Previous studies in our laboratory demonstrated the development of pulmonary inflammation in Nox2 deficient (gp91phox-/y) mice that was absent in WT mice in a murine model of SIRS. Given this finding, we hypothesized that Nox2 in a resident cell in the lung, specifically the alveolar macrophage, has an essential anti-inflammatory role. Using a murine model of SIRS, we examined whole-lung digests and bronchoalveolar lavage fluid (BALf) from WT and gp91phox-/y mice. Both genotypes demonstrated neutrophil sequestration in the lung during SIRS, but neutrophil migration into the alveolar space was only present in the gp91phox-/y mice. Macrophage inflammatory protein (MIP)-1alpha gene expression and protein secretion were higher in whole-lung digest from uninjected gp91phox-/y mice compared to the WT mice. Gene expression of MIP-1alpha, MCP-1, and MIP-2 was upregulated in alveolar macrophages obtained from gp91phox-/y mice at baseline compared with WT mice. Further, ex vivo analysis of alveolar macrophages, but not bone marrow-derived macrophages or peritoneal macrophages, demonstrated higher gene expression of MIP-1alpha and MIP-2. Moreover, isolated lung polymorphonuclear neutrophils migrate to BALf obtained from gp91phox-/y mice, further providing evidence of a cell-specific anti-inflammatory role for Nox2 in alveolar macrophages. We speculate that Nox2 represses the development of inflammatory lung injury by modulating chemokine expression by the alveolar macrophage. PMID- 30288636 TI - Statins Inhibit Cytokines in a Dose-Dependent Response in Patients with Systemic Sclerosis. AB - Although statins have been successfully administered in the treatment of hypercholesterolemia and cardiovascular disease due to their lipid-lowering and anti-atherosclerotic action, they have shown immunomodulatory effects in several studies with immune-mediated diseases. The aim of this study was to investigate the effects of statins treatment on Th1, Th2, and Th17 cytokines production from stimulated peripheral blood mononuclear cells (PBMCs) obtained from Systemic Sclerosis (SSc) patients. We recruited 21 patients classified according to the American College of Rheumatology criteria for SSc for PBMCs culture analysis. Cytokine levels (IL-2, IL-4, IL-6, IL-10, TNF, IFN-gamma, IL-17A, and IL-17F) were quantified by ELISA or CBA, and patients were assessed for clinical and exam's variables. Simvastatin and atorvastatin at 50 MUM promoted reduction in all cytokine levels with statistical significance, except for IL-6, which had its reduction only induced by the use of simvastatin. Statins, particularly simvastatin, appear to have an immunosuppressive effect in reducing all cytokine secretion levels from PBMCs of SSc in a dose-dependent manner. PMID- 30288637 TI - Ultrasound evaluation of fetal critical aortic stenosis using the left atrium area/cardiac area ratio and the Doppler patterns in the pulmonary veins. AB - In fetal critical aortic stenosis (AS), a double reverse pattern in the pulmonary veins (PVs) is associated with a poor prognosis. We evaluated the hemodynamic changes using PV Doppler and the left atrium area/cardiac area (LA/CA) ratio in a fetus at 28 weeks of gestation with critical AS complicated with hydrops fetalis, polyhydramnios, and cardiac abnormality. A markedly enlarged LA and severe mitral regurgitation with critical AS were detected, with LA/CA ratio = 0.40 and double reverse pattern with forward/reverse velocity time integral ratio (FRVR) = 1.18 on PV Doppler. After amniotic reduction at 31 weeks, the LA/CA ratio decreased (0.24) and the FRVR in PV increased (7.11). Forward flow through the fetal aorta was seen spontaneously, and hydrops fetalis was relieved with LA volume reduction. A male neonate weighing 2171 g was delivered via cesarean section at 36 weeks with an Apgar score of 5 and 6 at 1 and 5 min, respectively. He required atrial septal opening and bilateral pulmonary artery banding after birth, followed by Norwood operation. The double reverse pattern in PVs might be reversible. The change in FRVR in PVs and LA/CA ratio would be helpful in understanding the hemodynamic change in fetal critical AS. PMID- 30288638 TI - Ready player one? Autophagy shapes resistance to photodynamic therapy in cancers. AB - Photodynamic therapy (PDT) is a procedure used in cancer therapy that has been shown to be useful for certain indications. Considerable evidence suggests that PDT might be superior to conventional modalities for some indications. In this report, we examine the relationship between PDT responsiveness and autophagy, which can exert a cytoprotective effect. Autophagy is an essential physiological process that maintains cellular homeostasis by degrading dysfunctional or impaired cellular components and organelles via a lysosome-based pathway. Autophagy, which includes macroautophagy and microautophagy, can be a factor that decreases or abolishes responses to various therapeutic protocols. We systematically discuss the mechanisms underlying cell-fate decisions elicited by PDT; analyse the principles of PDT-induced autophagy, macroautophagy and microautophagy; and present evidence to support the notion that autophagy is a critical mechanism in resistance to PDT. A combined strategy involving autophagy inhibitors may be able to further enhance PDT efficacy. Finally, we provide suggestions for future studies, note where our understanding of the relevant molecular regulators is deficient, and discuss the correlations among PDT-induced resistance and autophagy, especially microautophagy. PMID- 30288639 TI - TAK1 mediates convergence of cellular signals for death and survival. AB - TGF-beta activated kinase 1, a MAPK kinase kinase family serine threonine kinase has been implicated in regulating diverse range of cellular processes that include embryonic development, differentiation, autophagy, apoptosis and cell survival. TAK1 along with its binding partners TAB1, TAB2 and TAB3 displays a complex pattern of regulation that includes serious crosstalk with major signaling pathways including the C-Jun N-terminal kinase (JNK), p38 MAPK, and I kappa B kinase complex (IKK) involved in establishing cellular commitments for death and survival. This review also highlights how TAK1 orchestrates regulation of energy homeostasis via AMPK and its emerging role in influencing mTORC1 pathway to regulate death or survival in tandem. PMID- 30288640 TI - Position and Content Paradigms in Genome Rearrangements: The Wild and Crazy World of Permutations in Genomics. AB - Modellers of large-scale genome rearrangement events, in which segments of DNA are inverted, moved, swapped, or even inserted or deleted, have found a natural syntax in the language of permutations. Despite this, there has been a wide range of modelling choices, assumptions and interpretations that make navigating the literature a significant challenge. Indeed, even authors of papers that use permutations to model genome rearrangement can struggle to interpret each others' work, because of subtle differences in basic assumptions that are often deeply ingrained (and consequently sometimes not even mentioned). In this paper, we describe the different ways in which permutations have been used to model genomes and genome rearrangement events, presenting some features and limitations of each approach, and show how the various models are related. This paper will help researchers navigate the landscape of permutation-based genome rearrangement models and make it easier for authors to present clear and consistent models. PMID- 30288641 TI - A Kinetic Analysis of Coupled (or Auxiliary) Enzyme Reactions. AB - As a case study, we consider a coupled (or auxiliary) enzyme assay of two reactions obeying the Michaelis-Menten mechanism. The coupled reaction consists of a single-substrate, single-enzyme non-observable reaction followed by another single-substrate, single-enzyme observable reaction (indicator reaction). In this assay, the product of the non-observable reaction is the substrate of the indicator reaction. A mathematical analysis of the reaction kinetics is performed, and it is found that after an initial fast transient, the coupled reaction is described by a pair of interacting Michaelis-Menten equations. Moreover, we show that when the indicator reaction is fast, the quasi-steady state dynamics are governed by three fast variables and one slow variable. Timescales that approximate the respective lengths of the indicator and non observable reactions, as well as conditions for the validity of the Michaelis Menten equations, are derived. The theory can be extended to deal with more complex sequences of enzyme-catalyzed reactions.

AB - This study was designed to screen the crossbred pigs for SNPs in five candidate genes, associated with pork quality traits and to differentiate their genotypes by PCR-RFLP. The results indicated that genotypes of crossbred pigs were NN (90%) and Nn (10%) for RYR1; RR (83%) and QR (17%) for PRKAG3; HH (98%), Hh (1%) and hh (1%) for HFABP; DD (99%) and CD (1%) for MYF-5; and AG (57%), GG (26%) and AA (17%) for MC4R SNPs, respectively. Allelic frequencies for five SNPs {RYR1 (1843C>T), PRKAG3 (c.599G>A), HFABP (c.1322C>T), MYF-5 (c.1205A>C) and MC4R (c.1426A>G)} were 0.95 and 0.05 (N/n), 0.08 and 0.92 (Q/R), 0.99 and 0.01 (H/h), 0.00 and 1.00 (C/D) and 0.45 and 0.55 (A/G), respectively. The effect of RYR1 (1843C>T) SNP was significant on pH45 (P < 0.05), pH24 (P < 0.05) and protein % (P < 0.05). The PRKAG3 (c.599G>A) and MC4R (c.1426A>G) SNP had significant association with dressing percentages. The results revealed that RYR1, PRKAG3 and MC4R SNPs may be used in marker associated selection for pork quality traits in crossbred pigs. PMID- 30288643 TI - TCF4 and GRM8 gene polymorphisms and risk of schizophrenia in an Iranian population: a case-control study. AB - TCF4 and GRM8, two significant genes involved in the normal nervous development and glutamate pathway, are thought to be involved in the pathogenesis of schizophrenia (SCZ). We aimed to explore the association of TCF4 and GRM8 gene polymorphisms with risk of SCZ. The rs8766 in TCF4 and rs712723 in GRM8 were selected for genotyping in a set of Iranian case-control samples including 215 patients and 220 matched healthy controls using polymerase chain reaction restriction fragment length polymorphism. Although rs8766 increased the OR, we found that rs8766 allele and genotype frequencies were not significantly different between case and control groups and a significant association cannot be suggested for the selected SNP. However, allele C and genotype CC (allele C: OR 1.48, 95% CI 1.13-1.94; genotype CC: OR 1.71, 95% CI 1.09-2.68) of rs712723 polymorphism was found to have a significant association with risk of SCZ. Frequency of allele C (P = 0.003) and genotype CC (P = 0.017) was higher in the schizophrenic patients, while allele T (P = 0.003) and genotype TT (P = 0.028) frequencies were found lower in patients. Our findings indicate that rs712723 in GRM8 may play an important role in the pathogenesis of SCZ. However, our conclusion needs to be confirmed in other population. PMID- 30288644 TI - SMER28 Attenuates Dopaminergic Toxicity Mediated by 6-Hydroxydopamine in the Rats via Modulating Oxidative Burdens and Autophagy-Related Parameters. AB - Parkinson's disease is the second most common neurodegenerative disease that occurs due to cellular autophagy deficiency and the accumulation of alpha synuclein in the dopaminergic neurons of the substantia nigra pars compacta (SNc) of the brainstem. The SMER28 (also known as 6-Bromo-N-prop-2-enylquinazolin-4 amine) is an autophagy inducer. In this study, the neuroprotective effects of SMER28 were evaluated on autophagy induction, antioxidant system activation, and microgliosis attenuation. The Parkinson's disease model was developed in the male Wistar rats by injection of 6-OHDA into the left striatum. Apomorphine-induced behavior assessment test and SNc cell counting were performed to investigate the neuroprotective effects of SMER28. This study examined the pharmacological roles of SMER28, especially by focusing on the autophagy (p62/ SQSTM1 and LC3II/LC3I ratio where LC3 is microtubule-associated protein 1A/1B-light chain 3), inhibiting free radicals, and activating the antioxidant system. The levels of malondialdehyde (MDA), reactive oxygen species (ROS), glutathione (GSH), GSH/glutathione peroxidase (GPX), superoxide dismutase (SOD) activity and nuclear factor-erythroid 2-related factor-2 (Nrf2) were measured to evaluate the antioxidant activity of SMER28. Moreover, Iba-1 (ionized calcium binding adaptor molecule, indicating microgliosis) and tyrosine hydroxylase immunoreactivities were evaluated in the SNc. In the behavioral assessment, SMER28 (50 ug/kg) attenuated damages to the SNc dopaminergic neurons, characterized by improved motor function. The tissue observations revealed that SMER28 prevented the destruction of SNc neurons and attenuated microgliosis as well. It also reduced MDA and ROS production and increased GSH, GPX, SOD, and Nrf2 activities by inducing autophagy (decreasing p62 and increasing LC3II/LC3I ratio). Consequently, possibly with further studies, it can be considered as a drug for neurodegenerative diseases with proteinopathy etiology.

PMID- 30288646 TI - Repeated Valsalva maneuvers promote symptomatic manifestations of cerebral microhemorrhages: implications for the pathogenesis of vascular cognitive impairment in older adults. AB - Multifocal cerebral microhemorrhages (CMHs, also known as "cerebral microbleeds"), which are associated with rupture of small intracerebral vessels, have been recognized as an important cause for cognitive decline in older adults. Although recent studies demonstrate that CMHs are highly prevalent in patients 65 and older, many aspects of the pathogenesis and clinical significance of CMHs remain obscure. In this longitudinal observational study, a case of a 77-year-old man with multifocal CMHs is described, in whom the rupture of intracerebral vessels could be linked to repeatedly performing extended Valsalva maneuvers. This patient was initially seen with acute aphasia after performing a prolonged Valsalva maneuver during underwater swimming. T2-weighted magnetic resonance imaging revealed a left acute frontal intracerebral hemorrhage (ICH) with multiple CMHs. The aphasia was resolved and no cognitive impairment was present. Two years later, he developed unsteadiness and confusion after performing two prolonged Valsalva maneuvers during underwater swimming separated by about 12 days. Repeat brain imaging revealed an acute right and a subacute left ICH, with a marked interval increase in the number of CMHs. The patient also exhibited manifest memory loss after the second admission and was diagnosed with dementia. These observations suggest that prolonged Valsalva maneuver is potentially a common precipitating cause of both CMHs and symptomatic ICHs. The Valsalva maneuver both increases the systolic arterial pressure and gives rise to a venous pressure wave transmitted to the brain in the absence of the competent antireflux jugular vein valves. This pressure increase is superimposed on existing hypertension and/or increases in blood pressure due to exercise and increased venous return due to immersion of the body in water. We advocate that further studies are needed to distinguish between CMHs with arterial and venous origins and their potential to lead to ICH induced by Valsalva maneuver as well as to determine whether these lesions have a predilection for a particular location. PMID- 30288647 TI - Distribution of polycyclic aromatic hydrocarbons (PAHs) in commonly consumed seafood from coastal areas of Bangladesh and associated human health implications. AB - Levels, distribution, possible sources and potential risks of 16 USEPA priority polycyclic aromatic hydrocarbons (PAHs) were investigated comprehensively in frequently consumed seafood species collected from the coastal areas of Bangladesh. Samples were collected in winter and summer, 2015. The total concentration of PAHs (?PAHs) in the examined seafood was 184.5-2806.6 ng/g wet weight (ww) in winter and 117.9-4216.8 ng/g ww in summer, respectively. The levels of ?PAHs were comparable to or higher than those reported from other coastal areas. Seasonal variation was not significant for the majority of the monitored PAHs. Spatial distribution revealed that the seafood collected from areas with recent urbanization and industrialization (Chittagong, Cox's Bazar and Sundarbans) was more contaminated with PAHs than those from the unindustrialized area (Meghna Estuary). Low-molecular-weight isomers dominated the PAH composition. Molecular ratios suggested the abundance of mixed sources of PAHs in the Bangladeshi coastal areas with a slight imposition toward the petrogenic origin. A preliminary evaluation of human health risk indicated that the dietary PAH exposure from consumption of Bangladeshi seafood would certainly induce adverse health effects. This finding suggests the need to enhance risk management regarding seafood consumption through public advisory in Bangladesh. PMID- 30288648 TI - Do Beliefs About Whether Others Can See Modulate Social Seeking in Autism? AB - Autistic people process gaze differently than typical people, but it is not yet clear if these differences lie in the processing of eye-shapes or the belief in whether others can see (perceptual mentalizing). We aimed to investigate whether these two models of gaze processing modulate social seeking in typical and autistic adults. We measured preferences of participants to view videos of an actress with visible or hidden eyes, who can or cannot see out. While typical participants preferred videos where the actress can see through and has visible eyes, autistic people showed no preference for these videos. These findings are discussed in the context of perceptual mentalizing and the social motivation theory of autism.

AB - Postoperative suture dehiscence is an important mode of short-term mitral and tricuspid valve (MV, TV) repair failure. We sought to evaluate suture pullout forces and collagen density in human atrioventricular valves for a better understanding of the comparative physiology between the valves and the underlying mechanobiological basis for suture retention. Mitral and tricuspid annuli were each excised from hearts from human donors age 60-79 with no history of heart disease (n = 6). Anchor sutures were vertically pulled until tearing through the tissue. Suture pullout force (FP) was measured as the maximum force at dehiscence. Subsequently, tissue samples from each tested suture position were evaluated for collagen content using a standard hydroxyproline assay. Among all mitral positions, no significant differences were detected among positions or regions with mean FP values falling between 6.9 +/- 2.6 N (posterior region) and 10.3 +/- 4.7 N (anterior region). Among all tricuspid positions, the maximum FP and minimum FP were 24.0 +/- 9.2 N (trigonal region) and 4.5 +/- 2.6 N (anterior region). Although for the MV, a given sample's collagen content had no correlation to its corresponding FP, the same relationship was significant for the TV. Further, the TV exhibited comparable FP to the MV overall, despite a nearly 40% reduction in collagen content. These findings suggest that sutures placed in the trigonal region of the TV have higher pullout force than those placed along other segments of the annuli. Furthermore, there are likely differences in collagen orientation between the mitral and tricuspid annuli, such that collagen content strongly impacts FP in one, but not the other.

AB - BACKGROUND: Systemic inflammatory response, as measured by C-reactive protein (CRP), is associated with prognosis in various types of human malignancies. However, to the best of our knowledge, the clinical significance of CRP in patients with locally advanced rectal cancer that undergo preoperative chemoradiation has not been investigated in detail. This retrospective study validates CRP as a potential predictive marker for survival outcomes in rectal cancer patients. METHODS: In this study, we enrolled 125 patients that received total mesorectal excision after preoperative chemoradiation for rectal cancer between January 2003 and December 2010. We investigated the association between preoperative CRP and clinicopathological characteristics and assessed the prognostic value of CRP. RESULTS: The median follow-up was 41 months. Elevated CRP showed significant correlation with high histological grade (P = 0.009) and cancer recurrence (P = 0.027). The 5-year disease-free survival and cancer specific survival were significantly lower in the elevated CRP group (P = 0.001). Moreover, CRP was the strongest predictive factor for cancer-specific survival in multivariate analysis (P = 0.001). In the subgroup analysis, elevated CRP was a significant prognostic factor in patients with node-positive disease (P = 0.025) and was associated with poorer tumor regression (TRG4-5; P = 0.011). CONCLUSIONS: The results of our study suggest that preoperative CRP level shows prognostic significance in rectal cancer patients that have undergone chemoradiation. Therefore, preoperative CRP may help clinicians to identify patients that need additional therapy to reduce systemic failure. PMID- 30288656 TI - Intercalated discs: cellular adhesion and signaling in heart health and diseases. AB - Intercalated discs (ICDs) are highly orchestrated structures that connect neighboring cardiomyocytes in the heart. Three major complexes are distinguished in ICD: desmosome, adherens junction (AJ), and gap junction (GJ). Desmosomes are major cell adhesion junctions that anchor cell membrane to the intermediate filament network; AJs connect the actin cytoskeleton of adjacent cells; and gap junctions metabolically and electrically connect the cytoplasm of adjacent cardiomyocytes. All these complexes work as a single unit, the so-called area composita, interdependently rather than individually. Mutation or altered expression of ICD proteins results in various cardiac diseases, such as ARVC (arrhythmogenic right ventricular cardiomyopathy), dilated cardiomyopathy, and hypotrophy cardiomyopathy, eventually leading to heart failure. In this article, we first review the recent findings on the structural organization of ICD and their functions and then focus on the recent advances in molecular pathogenesis of the ICD-related heart diseases, which include two major areas: i) the ICD gene mutations in cardiac diseases, and ii) the involvement of ICD proteins in signal transduction pathways leading to myocardium remodeling and eventual heart failure. These major ICD-related signaling pathways include Wnt/beta-catenin pathway, p38 MAPK cascade, Rho-dependent serum response factor (SRF) signaling, calcineurin/NFAT signaling, Hippo kinase cascade, etc., which are differentially regulated in pathological conditions. PMID- 30288657 TI - Genome-wide exploration of C2H2 zinc finger family in durum wheat (Triticum turgidum ssp. Durum): insights into the roles in biological processes especially stress response. AB - C2H2 type of zinc finger transcription factors (C2H2-ZFP TFs) play crucial roles in plant developments and stress response. Regarding its importance, genome-wide study of C2H2-ZFs were performed in multiple important plant species, but any such investigation was not fulfilled in Triticum turgidum ssp. Durum (durum wheat) as an important nutritional crop. The present study identified 122 C2H2 ZFs in durum wheat and physically mapped them onto the genome. The phylogenetic analysis classified these TFs into six major groups. Genes structure and conserved motifs assay showed TtC2H2-ZF involvement in the important cellular functions. Comparative phylogeny between durum wheat TtC2H2-ZF genes and the orthologs in rice revealed the evolutionary relationships of C2H2-ZF proteins. The gene ontology and promoter cis-element analysis indicated that most of TtC2H2 ZF genes are involved in multiple molecular functions including metal ion-binding and various stimuli responses. Further, the miRNAs targeting TtC2H2-ZF transcripts, homology modeling and proteins interaction network were also demonstrated, suggesting the vital cellular functions of TtC2H2-ZFs during various circumstances. The expression heatmap demonstrated differential and tissue-specific expression patterns of these genes. Expression profiling of this gene family members in response to dehydration and heat stresses showed differential expression pattern of these genes at multiple time points of stresses. This study can prepare a comprehensive overview of the durum wheat C2H2 ZF gene family and may provide a new perspective on the evolution of them, which will form the basis for further investigation of the roles of this family members and future genetic engineering studies in crops. PMID- 30288658 TI - Selenium-Rich Yeast protects against aluminum-induced peroxidation of lipide and inflammation in mice liver. AB - To investigate the effect of Selenium Rich Yeast (SeY) on hepatotoxicity of Aluminium (Al), SeY (0.1 mg/kg) was orally administrated to aluminium-exposed mice (10 mg/kg) for 28 days. The risk of oxidative stress was assessed by detecting the total antioxidant capacity (T-AOC), catalase activity, H2O2 content, and mRNA levels of the Keap1/Nrf-2/HO-1 pathway. Inflammatory reactions were assessed by detecting the mRNA levels of inflammatory biomarkers. Our results showed that SeY protected against the liver histological changes induce by Al. The body weight gain of mice treated with SeY + Al restore to normal compare with mice exposed to Al alone. Al treatment significantly decreased the activities of antioxidant enzymes, reduced T-AOC levels, and up-regulated the mRNA level of Nrf2 and HO-1, thereby ultimately leading to peroxidation. SeY shown a significant protective effect against oxidative stress caused by Al. In addition, Al exposure induced inflammatory responses in rat liver by promoting the release of inflammatory cytokines (TNF-a, NF-kB, TNF-R1, IL-1, IL-6, and COX 2). SeY protected against changes in liver by regulating the mRNA expression levels of inflammatory factors. These results suggested that Se protected the liver from the Al-induced hepatotoxicity by regulating the mRNA level of Keap1/Nrf2/HO-1, and inhibited inflammatory responses by down-regulating the expression level of inflammatory cytokine. PMID- 30288659 TI - Clinical Significance of the Thioredoxin System and Thioredoxin-Domain-Containing Protein Family in Hepatocellular Carcinoma. AB - BACKGROUND: Oxidative stress occurs due to the excessive generation of cellular reactive oxygen species and antioxidant system dysfunction. The thioredoxin (TXN) system and TXN-domain-containing protein (TXNDC) family form networks maintaining the cellular reducing environment. Recently, the importance of these genes in the tumor environment has been emphasized. AIM: To investigate the clinical significance of TXNs and TXNDC family members in HCC. METHODS: Genomic data from 367 hepatocellular carcinoma (HCC) patients who underwent hepatic resections were analyzed to determine genetic alterations in mRNA and protein levels between patients and healthy controls. In addition, functional enrichment and survival analyses were performed. RESULTS: HCC patients were shown to have enhanced expression of TXN, TXNRD1, and TXNDC7/9/14 mRNA and protein compared with controls. In accordance with the survival analyses, strong associations were found that patients with TXN, TXNRD1, and TXNDC1/7/9 alterations were proven to have poor prognosis in overall survival. Moreover, gene set enrichment analysis and network analyses revealed that positive correlations were found in mRNA expression of TXN, TXNRD1, and TXNDC7/9 genes with upregulation of the tumor promoting genes, specifically mTORC1, E2F targets, and Myc targets. On the other hand, elevated expressions of TXNIP and TXNDC11 genes were correlated with suppression of the above tumor-promoting genes. CONCLUSIONS: TXN system and TXNDC family gene panel obtained from the resected tissue of the HCC patients could be used to predict survival prognosis of HCC, and these genes could be considered as potential therapeutic targets for improving HCC survival.

Unfortunately, the antifibrotic agents are limited. Thrombin activates hepatic stellate cells (HSCs). Therefore, we investigated the effects of a direct thrombin inhibitor, dabigatran, on liver fibrosis. METHODS: Adult male Sprague-Dawley rats were injected intraperitoneally with thioacetamide (TAA, 200 mg/kg twice per week) for 8 or 12 weeks to induce liver fibrosis. The injured rats were assigned an oral gavage of dabigatran etexilate (30 mg/kg/day) or vehicle in the last 4 weeks of TAA administration. Rats receiving an injection of normal saline and subsequent oral gavage of dabigatran etexilate or vehicle served as controls. RESULTS: In the 8-week TAA-injured rats, dabigatran ameliorated fibrosis, fibrin deposition, and phosphorylated ERK1/2 in liver, without altering the transcript expression of thrombin receptor protease activated receptor-1. In vitro, dabigatran inhibited thrombin-induced HSC activation. Furthermore, dabigatran reduced intrahepatic angiogenesis and portal hypertension in TAA-injured rats. Similarly, in the 12-week TAA-injured rats, a 4 week treatment with dabigatran reduced liver fibrosis and portal hypertension. CONCLUSIONS: By inhibiting thrombin action, dabigatran reduced liver fibrosis and intrahepatic angiogenesis. Dabigatran may be a promising therapeutic agent for treatment of liver fibrosis.

AB - Objectives The Advisory Committee on Immunization Practices (ACIP) and the American College of Obstetricians and Gynecologists (ACOG) recommend that pregnant women receive the Tdap vaccine during every pregnancy. The objectives of this paper are to evaluate disparities in Tdap vaccination among pregnant women in the U.S., and to assess whether race/ethnicity and other characteristics are associated with factors that inform pregnant women's decisions about Tdap vaccination. Methods We conducted a nationwide cross-sectional web-based survey of pregnant women in the U.S. during June-July 2014. The primary outcome was self reported vaccination status with Tdap during pregnancy, categorized as vaccinated, unvaccinated with intent to be vaccinated during the current pregnancy, and unvaccinated with no intent to be vaccinated during the current pregnancy. Secondary outcomes included factors that influenced women's decisions about vaccination and information needs. We used multivariable logistic regression models to estimate odds ratios for associations between race/ethnicity and the outcomes. Results Among pregnant women who completed the survey, 41% (95% CI 36-45%) reported that they had received Tdap during the current pregnancy. Among those women in the third trimester at the time of survey, 52% (95% CI 43 60%) had received Tdap during the current pregnancy. Hispanic women had higher Tdap vaccination than white women and black women (53%, p < 0.05, compared with 38 and 36%, respectively). In logistic regression models adjusting for maternal age, geographic region, education, and income, Hispanic women were more likely to have been vaccinated with Tdap compared with white women (aOR 2.29, 95% CI 1.20 4.37). Higher income and residing in the western U.S. were also independently associated with Tdap vaccination during pregnancy. Twenty-six percent of surveyed women had not been vaccinated with Tdap yet but intended to receive the vaccine during the current pregnancy; this proportion did not differ significantly by race/ethnicity. The most common factor that influenced women to get vaccinated was a health care provider (HCP) recommendation. The most common reason for not getting vaccinated was a concern about safety of the vaccine. Conclusions This study found that some disparities exist in Tdap vaccination among pregnant women in the U.S., and HCPs have an important role in providing information and recommendations about the maternal Tdap recommendation to pregnant women so they can make informed vaccination decisions.

AB - Postoperative visual function is a major concern in transsphenoidal surgery (TSS). Although several reports have demonstrated the importance of visual evoked potential (VEP) monitoring during TSS, the usefulness of VEP monitoring have been controversial because of its reproducibility. Efficacy of VEP was analyzed in 20 consecutive cases of patients who underwent endoscopic endonasal TSS surgery. We adapted a high-power light-emitting diode stimulator with electroretinography using venous anesthesia. In addition, we used black shield patch and braided codes to obtain reproducible VEP amplitudes. Stable and reproducible VEP waveforms were obtained in 38 of 39 eyes (97.4%) before surgery. Fifteen eyes had deteriorated VEP amplitude during operation, and nine eyes had improved VEP amplitude at the end of surgery, and six eyes had not improved VEP amplitude. But no postoperative visual impairment was observed in all cases by temporary halting the surgical manipulation when the VEP was deteriorated. In conclusion, VEP monitoring could be a warning sign to avoid postoperative visual dysfunction. We recommend VEP as a routine monitoring in TSS. PMID- 30288663 TI - The Time Course of Dorsal and Rostral-Ventral Anterior Cingulate Cortex Activity in the Emotional Stroop Experiment Reveals Valence and Arousal Aberrant Modulation in Patients with Schizophrenia. AB - This paper aims to investigate the temporal dynamics within the dorsal anterior cingulate cortex (dACC) and the rostral-ventral (rv) ACC during the interaction of emotional valence and arousal with cognitive control in patients with Schizophrenia (SZ). Although cognitive deficits in SZ are highly relevant and emotional disturbances are common, the temporal relationship of brain regions involved in the interaction of emotional and cognitive processing in SZ is yet to be determined. To address this issue, the reaction time (RT), event-related potential (ERP) and temporal dynamics of the dACC and rvACC activity were compared between SZ subjects and healthy controls (HC), using a modified emotional Stroop experiment (with factors namely congruence, arousal and valence). EEG was recorded with 64 channels and source localisation was performed using the sLORETA software package. We observed slower initial increase and lower peaks of time course activity within the dACC and rvACC in the SZ group. In this particular group, the dACC activity during late negativity was negatively correlated with a significantly higher RT in the high arousal conflict condition. In contrast to HC subjects, at the N450 window, there was no significant valence (ERP and rvACC ROI) modulation effect in the SZ subjects. Using high density EEG and source localisation, it was possible to distinguish various disturbances within the dACC and rvACC in patients with SZ, during emotion-cognition processing. PMID- 30288664 TI - Does proton pump inhibition change the on-treatment anti-Xa activity in xabans treated patients with atrial fibrillation? A pilot study. AB - Proton pump inhibition (PPI) reduces gastrointestinal bleeding on direct oral anticoagulants. However, PPI may affect dabigatran on-treatment levels; and there is no information regarding the effect of PPI on xabans on-treatment activity. Thus, the aim of this study was to determine the impact of PPI on therapeutic anti-Xa activity in rivaroxaban- and apixaban-treated patients with atrial fibrillation (AF). This single-centre pilot prospective study enrolled 77 consecutive xabans-treated patients (42 rivaroxaban-treated and 35 apixaban treated patients) with AF. PPI was administrated in 44 patients. Trough and peak anti-Xa activity was assessed with factor Xa-calibrated anti-Xa chromogenic analysis. There were no significant differences in trough anti-Xa activity comparing PPI-treated patients and patients without PPI (80.5 +/- 66.5 ng/mL in PPI group vs. 71.6 +/- 64.1 ng/mL in non-PPI group, p = 0.57, Table 2). Similarly, there were no significant differences in peak anti-Xa activity between compared groups (175.2 +/- 102.5 ng/mL in PPI group vs. 202.9 +/- 84.1 ng/mL in non-PPI group, p = 0.21). This pilot study did not reveal significant changes in xabans on-treatment anti-Xa activity according the PPI status.

PMID- 30288666 TI - Work disability and its determinants in patients with pituitary tumor-related disease. AB - INTRODUCTION: Pituitary tumors may have a considerable impact on patients' functional status, including paid employment, yet research in this area is sparse. OBJECTIVE: To describe work disability and its determinants in patients treated for a pituitary tumor. METHODS: Cross-sectional study including patients treated for a pituitary tumor in the working age (18-65 years), who completed five validated questionnaires assessing work disability [Short Form-Health and Labour Questionnaire, Work Role Functioning Questionnaire 2.0 (WRFQ)], health related quality of life (HRQoL) and utility (Short Form-36, EuroQoL) and disease burden (Leiden Bother and Needs Questionnaire-Pituitary). Additional data were extracted from the medical records (age, gender, tumor type, treatment, date of diagnosis) and self-reports (marital status, education, endocrine status). Associations of disease-specific and sociodemographic characteristics, HRQoL, and disease burden with (not) having a paid job were examined through multivariate logistic regression. RESULTS: We included 241 patients (61% female, median age 53 years, median time since diagnosis 11 years), of whom 68 (28%) were without a paid job. Patients who had acromegaly, Cushing's disease, (pan)hypopituitarism, radiotherapy, were single, less educated, lower HRQoL, and increased disease burden were more often without a paid job (p < 0.05). Among those with paid jobs, 41% reported health-related absenteeism in the previous year. The three work incapacitating problems reported by the largest proportion of patients were within the mental and social domain (WRFQ). CONCLUSION: Work disability among patients treated for a pituitary tumor is substantial. As impact on social functioning is high, it is strongly advised to incorporate work disability during clinical guidance of patients. PMID- 30288668 TI - L-Norvaline Reverses Cognitive Decline and Synaptic Loss in a Murine Model of Alzheimer's Disease. AB - The urea cycle is strongly implicated in the pathogenesis of Alzheimer's disease (AD). Arginase-I (ARGI) accumulation at sites of amyloid-beta (Abeta) deposition is associated with L-arginine deprivation and neurodegeneration. An interaction between the arginase II (ARGII) and mTOR-ribosomal protein S6 kinase beta-1 (S6K1) pathways promotes inflammation and oxidative stress. In this study, we treated triple-transgenic (3*Tg) mice exhibiting increased S6K1 activity and wild type (WT) mice with L-norvaline, which inhibits both arginase and S6K1. The acquisition of spatial memory was significantly improved in the treated 3*Tg mice, and the improvement was associated with a substantial reduction in microgliosis. In these mice, increases in the density of dendritic spines and expression levels of neuroplasticity-related proteins were followed by a decline in the levels of Abeta toxic oligomeric and fibrillar species in the hippocampus. The findings point to an association of local Abeta-driven and immune-mediated responses with altered L-arginine metabolism, and they suggest that arginase and S6K1 inhibition by L-norvaline may delay the progression of AD. PMID- 30288669 TI - Comparison between Enteroscopy-Based and Laparoscopy-Assisted ERCP for Accessing the Biliary Tree in Patients with Roux-en-Y Gastric Bypass: Systematic Review and Meta-analysis. AB - Although balloon-assisted enteroscopy-endoscopic retrograde cholangiopancreatography (BAE-ERCP) is a well-described means of accessing the duodenal papilla in patients with Roux-en-Y gastric bypass (RYGB), it is associated with modest clinical success rates. Laparoscopy-assisted ERCP (LA ERCP)-performed by advancing a standard duodenoscope through a gastrostomy into the excluded stomach and duodenum-has emerged as a viable alternative to BAE ERCP, with apparently higher success rates. In this systematic review, we compare LA-ERCP with enteroscopy-based techniques in post-RYGB patients, including 22 case series that provided data on papilla identification, papilla cannulation, and complications. We found that LA-ERCP was superior to the enteroscopy-based techniques in its capacity to reach the duodenal papilla, although complication rates were lower for the latter. Comparative studies are needed in order to corroborate our findings. PMID- 30288667 TI - Contributions of TaSUTs to grain weight in wheat under drought. AB - KEY MESSAGE: The homologous genes to OsSUT1-5 in wheat were identified and detailed analysed. TaSUT1 was the predominant sucrose transporter group and it illustrated the genotypic variations towards drought during grain filling. Sucrose transporters (SUT) play crucial roles in wheat stem water soluble carbohydrate (WSC) remobilization to grain. To determine the major functional SUT gene groups in shoot parts of wheat during grain development, drought tolerant varieties, Westonia and Kauz, were investigated in field drought experiments. Fourteen homologous genes to OsSUT1-5 were identified on five homeologous groups, namely TaSUT1_4A, TaSUT1_4B, TaSUT1_4D; TaSUT2_5A, TaSUT2_5B, TaSUT2_5D; TaSUT3_1A, TaSUT3_1D; TaSUT4_6A, TaSUT4_6B, TaSUT4_6D; TaSUT5_2A, TaSUT5_2B, and TaSUT5_2D, and their gene structures were analysed. Wheat plants above the ground were harvested from pre-anthesis to grain maturity and the stem, leaf sheath, rachis, lemma and developing grain were used for analysing TaSUT gene expression. Grain weight, thousand grain weight, kernel number per spike, biomass and stem WSC were characterized. The study showed that among the five TaSUT groups, TaSUT1 was the predominant sucrose transporting group in all organs sampled, and the expression was particularly high in the developing grain. In contrast to TaSUT1, the gene expression levels of TaSUT2, TaSUT3 and TaSUT4 were lower, except for TaSUT3 which showed preferential expression in the lemma before anthesis. The TaSUT5 gene group was very weakly expressed in all tissues. The upregulated gene expression of TaSUT1 Westonia type in stem and grain reveal a crucial role in stem WSC remobilization to grain under drought. The high TaSUT1 gene expression and the significant correlations with thousand grain weight (TGW) and kernel number per spike demonstrated the contribution in Kauz's high grain yield in an irrigated environment and high TGW in Westonia under drought stress. Further molecular level identification is required for gene marker development. PMID- 30288670 TI - Is There a Better Design for a Bariatric Procedure? The Case for a Single Anastomosis Duodenal Switch. AB - The majority of bariatric surgical stapling procedure concepts were developed prior to the understanding of obesity as an energy storage disease. Conventional treatments did not consider the impact of macronutrients on hormones and glucose variability. Current recommendations suggest diets low in glycemic load, with moderate protein and unsaturated fat. Roux-en-Y gastric bypass promotes glucose variability which can be harmful for health and encourage weight regain. Classic duodenal switch with short common channels may prevent absorption of measurable fat-soluble vitamins and frequently untested essential fatty acids. The purpose of this review is to discuss these factors and explain why single anastomosis duodenal switch reduces glucose variability, allows for absorption of critical fats and fat-soluble vitamins, and has potential to offer better weight loss and metabolic outcomes. PMID- 30288671 TI - Order matters: Alphabetizing in-text citations biases citation rates. AB - Though citations are critical for communicating science and evaluating scholarly success, properties unrelated to the quality of the work-such as cognitive biases can influence citation decisions. The primacy effect, in particular, is relevant to lists, which for in-text citations could result in citations earlier in the list receiving more attention than those later in the list. Therefore, how citations are ordered could influence which citations receive the most attention. Using a sample of 150,000 articles, we tested whether alphabetizing in-text citations biases readers into citing more often articles with first authors whose surnames begin with letters early in the alphabet. We found that surnames earlier in the alphabet were cited more often than those later in the alphabet when journals ordered citations alphabetically compared with chronologically or numerically. This effect seemed to be stronger in psychology journals (which have a culture of alphabetizing citations) compared with biology or geoscience journals (which primarily order chronologically or numerically) and was strongest among moderately and highly cited articles. Therefore, alphabetizing in-text citations biases citation decisions toward authors with surnames occurring early in the alphabet. These citation decisions result from an interaction between cognitive biases (more attention devoted to items earlier in a list) and the structure of the citation environment (the style in which citations are ordered). We suggest that journals using alphabetically ordered citations switch to chronological ordering to minimize this arbitrary alphabetical citation bias. PMID- 30288673 TI - Activation of peroxymonosulfate by Fe-N complexes embedded within SBA-15 for removal of organic contaminants via production of singlet oxygen. AB - Persulfates are recognized as promising oxidants and an alternative to Fenton reaction for water treatment. However, activation methods in hand restrict the practical application. Herein, we explore the possibility of Fe-N complexes being a catalyst for persulfate activation for the first time. The catalyst denoted as Fe-Im-SBA was synthesized from ferric chloride, imidazole, and SBA-15 at high temperature. The internal pore structure of Fe-Im-SBA was maintained well; Fe, N and C elements are evenly distributed on the catalyst. This catalyst presents an extraordinarily catalytic activity for Rh B removal by PMS activation with a removal rate of Rh B that reached up to 97.0% in the first 5 min. It also performed well in a wide pH range with complete removal of Rh B in pH ranged from 0.5 to 10, suggesting the stability of this catalyst in both acidic and alkaline conditions. It also showed high adaptability to degrade different kinds of pollutants, which could give an attractive advantage of Fe-Im-SBA for environmental implications. Through X-ray absorption spectroscopies analysis, it shows that the active sites of Fe-Im-SBA are composed of Fe-N4 sites and Fe2-N2 sites. 1O2 were proved to generate in the Fe-Im-SBA/PMS system and serve as the major ROS. Meanwhile, graphitic carbon can accelerate the transfer of electrons, which may also be the reason for its high catalytic performance. PMID- 30288672 TI - Distribution of organic and inorganic mercury in the tissues and organs of fish from the southern Baltic Sea. AB - The aim of this study was to determine the distribution of total mercury (THg), methylmercury (CH3Hg+), and inorganic mercury (Hginorg) in the tissues and organs of fish depending on species, tissue, and organ, and their bioaccumulation in tissues and biomagnification throughout the trophic web. The study included four species of fish (herring, sprat, cod, and eel) from the southern Baltic Sea. The concentrations of the different forms of mercury were determined in tissues and internal organs. Intra-specific differences in levels of THg, CH3Hg+, and Hginorg in the tissues and organs were determined. Muscle contained the highest proportions of THg and CH3Hg+ in comparison to that in the internal organs. Differences in concentrations of THg, CH3Hg+, and Hginorg in the tissues and organs of fish were related to their preferred prey. The bioaccumulation of CH3Hg+ in the tissues and organs of predatory fish at the highest trophic levels was greater than in the liver and digestive tract of fish species at lower trophic levels, in which Hginorg predominated. The high concentrations of CH3Hg+ in eel and cod and the low levels in herring and sprat were linked with their food and the transfer of this element among species. The results suggested that the type of food, feeding habits, and trophic position were important parameters that influenced the transfer and biomagnification of mercury in fish. PMID- 30288674 TI - Dietary propionic acid enhances antibacterial and immunomodulatory effects of oxytetracycline on Nile tilapia, Oreochromis niloticus. AB - This study was carried out to evaluate the potential antibacterial and immunomodulatory effects of the dietary acidifier propionic acid (PA) when given alone or in combination with oxytetracycline (OTC) on Nile tilapia (Oreochromis niloticus). Apparently healthy O. niloticus (n = 240; 52 +/- 3.75 g) were randomly allocated into four equal groups (n = 60/group): control group fed a basal diet alone and the other three groups fed basal diets supplemented with either PA (200 mg /kg of diet, PA group) or OTC (500 mg/kg of diet, OTC group) alone or in combination (PA + OTC group). Each group was subdivided into two subgroups (n = 30/subgroup, each subgroup had triplicate of 10 fish); subgroup (A) was used to evaluate the antibacterial effects with the aforementioned 2 weeks feeding regime, and subgroup (B) was used to evaluate the immunomodulatory effects against Aeromonas hydrophila infection with similar 2 weeks feeding regime. Among the four groups, PA + OTC group showed the highest significant (p < 0.0001) antibacterial activity as indicated by widest inhibition zones against A. hydrophila and lowest total gastrointestinal bacterial counts. Additionally, this group had the best immunomodulatory effect as noticed by a significant (p < 0.05) increase in total serum protein, globulin, IgM, phagocytic activity and index, lysosome activity, and significant (p < 0.05) upregulation in the expression levels of immunity-related genes (MHC I, MHC IIA, MHC IIB, Tlr7, IgM heavy chain, TNFalpha, and IL1beta) in head-kidney. Notably, the combined dietary PA and OTC improved the hematological parameters and reduced the oxidative damage of hepatopancreas and head-kidney induced by OTC. This data suggests dietary PA as potential adjuvant to OTC in O. niloticus diets to get maximal antibacterial and immunomodulatory effects.

PMID- 30288675 TI - Risk assessment of some organic contaminants: a case study based on food consumption in Tanta and Ismailia cities, Egypt. AB - The impact of some organic pollutants on some residents of Tanta and Ismailia cities of Egypt through their consumption of vegetables, fruits and fish (Nile tilapia and catfish) was examined. Residues of organochlorine (OCS) and organophosphorus (OPS) as some polychlorinated biphenyls (PCBS) were compared with pesticides as well maximum residue limits (MRLS). Probable health risk to consumers was also assessed. P, P'-DDT, P, P'-DDE, P, P'-DDD, endrin, alpha-BHC, (lindane), and hexachlorbenzene (HCB) were the most detected organochlorine compounds, but did not exceed MRLs.However, OPS residues were the most frequently detected contaminants. PCBs congeners 28, 70, 52, and 180 were detected in tilapia fish from Tanta, but congeners 28 and 180 were the only detected congeners in samples collected from Ismailia region. ?PCBS values in all matrices did not exceed MRLS. Hazard index (HI) exhibited unity for all compounds at 50 the decreasing order: catfish > vegetables > fruits > Nile tilapia in Tanta, while in Ismailia the order was Nile tilapia > fruit > vegetables. Results also revealed that risk values for adults were greater than those of children categories. PMID- 30288677 TI - Peak Neutrophil-to-Lymphocyte Ratio Correlates with Clinical Outcomes in Patients with Severe Traumatic Brain Injury. AB - BACKGROUND: Studies suggested that the neutrophil-to-lymphocyte ratio (NLR) was associated with unfavorable outcomes in different diseases such as intracerebral hemorrhage, cardiovascular problem, cancer, and severe traumatic brain injury (sTBI). We aimed to evaluate the relationship between peak NLR and 1-year outcomes in patients with sTBI. METHODS: We retrospectively reviewed the clinical data of patients with sTBI who were treated in our department between January 2013 and January 2017. NLRs between day 1 and day 12 after admission as well as other related indicators were collected. The relationship between peak NLR and 1 year outcomes was analyzed. Factors associated with larger peak NLR were also explored. RESULTS: A total of 316 patients were included, and 81.3% (257/316) experienced unfavorable outcomes. Peak NLR was identified as an independent predictor for unfavorable outcomes after sTBI in multivariable logistic regression analysis (odds ratio, 1.086; 95% confidence interval, 1.037-1.137; P < 0.001). Its predictive value was confirmed by receiver operating characteristic analysis (area under curve = 0.775; P < 0.001). The day 1 NLR as well as admission Glasgow Coma Scale score was independently correlated with increased peak NLR. CONCLUSION: Peak NLR was associated with the clinical prognosis after sTBI and was a promising predictor for 1-year outcomes. PMID- 30288679 TI - Coronary microvascular dysfunction: Filling the research gaps with careful patient selection. PMID- 30288680 TI - Long-term prognostic value of quantitative myocardial perfusion in patients with chest pain and normal coronary arteries. AB - BACKGROUND: Patients with chest pain and no obstructive coronary artery disease have shown a high incidence of major adverse cardiovascular events (MACE). We evaluated the role of absolute myocardial perfusion quantification in predicting all-cause mortality and MACE during long-term follow-up in this group of patients. METHODS: We studied 79 patients who underwent Nitrogen-13 ammonia PET for quantification of global myocardial blood flow (MBF) and myocardial flow reserve (MFR) due to suspected impaired myocardial perfusion. Patients with coronary artery disease (i.e., > 30% stenosis in one or more coronary arteries) were excluded. We assessed all-cause mortality and MACE. MACE was defined as the composite incidence of death, myocardial infarction (MI), or hospitalization due to heart failure. RESULTS: Median follow-up was 8 (IQR: 3-14) years. Univariate Cox regression showed that only MFR (P = 0.01) was a predictor of all-cause mortality. Univariate Cox regression analysis showed that both MFR and Stress MBF were predictors of the composite endpoint of MACE (P < 0.001 and P = 0.01, respectively). CONCLUSION: Quantitative assessment of myocardial perfusion may predict all-cause mortality and MACE in patients with chest pain and normal coronary arteries in the long-term follow-up. PMID- 30288678 TI - Non-granulomatous cerebellar infection by Acanthamoeba spp. in an immunocompetent host. AB - Acanthamoeba spp. is a free-living amoeba, frequently involved in keratitis by contact lens in immunocompetent hosts. Anecdotal reports associate Acanthamoeba spp. as a cause of severe granulomatous encephalitis in immunocompromised and, less frequently, in immunocompetent subjects. Data regarding clinical and therapeutic management are scanty and no defined therapeutic guidelines are available. We describe an unusual case of non-granulomatous Acanthamoeba cerebellitis in an immunocompetent adult male, with abrupt onset of neurological impairment, subtle hemorrhagic infarction at magnetic resonance imaging, and initial suspicion of cerebellar neoplasm. Histopathological findings of excised cerebellar mass revealed the presence of necrosis and inflammation with structure resembling amoebic trophozoites, but without granulomas. Polymerase chain reaction from cerebellar tissue was positive for Acanthamoeba T4 genotype. Due to gastrointestinal intolerance to miltefosine, the patient was treated with long term course of fluconazole and trimethoprim/sulphamethoxazole, obtaining complete clinical and neuroradiological resolution.

PMID- 30288682 TI - Safety, Tolerability, and Pharmacokinetics of the Novel Anti-influenza Agent Baloxavir Marboxil in Healthy Adults: Phase I Study Findings. AB - BACKGROUND AND OBJECTIVE: Baloxavir marboxil, a prodrug that is metabolized to baloxavir acid, suppresses viral replication by inhibiting cap-dependent endonuclease. This first-in-human phase I study evaluated the safety, tolerability, and pharmacokinetics of baloxavir marboxil/baloxavir acid in healthy Japanese volunteers (Study 1), while food effects were evaluated in a separate phase I, crossover study in healthy Japanese volunteers (Study 2). METHODS: Study 1 participants were randomized to single-dose oral baloxavir marboxil (6, 20, 40, 60, or 80 mg; n = 6 per dose) or placebo (n = 10), while Study 2 participants (n = 15) received single-dose oral baloxavir marboxil 20 mg in fasted, fed, and before-meal states. RESULTS: Baloxavir marboxil was well tolerated; there were few treatment-emergent adverse events and no serious adverse events/deaths. The mean plasma baloxavir acid concentration 24 h after single-dose (C24) oral baloxavir marboxil 6 mg was 6.92 ng/mL, exceeding the target C24 (6.85 ng/mL) estimated in nonclinical studies. In Study 1, baloxavir acid exposure demonstrated dose-proportional increases in the fasted state, with maximum plasma concentration generally attained within 3.5 h. Terminal elimination half-life ranged from 49 to 91 h. In Study 2, exposure was decreased and apparent clearance increased in the fed and before-meal states versus the fasted state; however, exposure exceeded the target C24 in all states. CONCLUSION: Single-dose oral baloxavir marboxil was well tolerated, had a favorable safety profile, and had favorable pharmacokinetic characteristics, including a long half-life, supporting single oral dosing. The baloxavir acid area under the plasma concentration-time curve decreased with food intake by approximately 40%.

AB - The Multi-component HIV Intervention Packages for Chinese MSM (China MP3) project sought to facilitate engagement in care and initiation of antiretroviral therapy among newly HIV-diagnosed men who have sex with men in Beijing, China through the implementation of in-person peer-counseling (PC) and a weekly short message service (SMS)-based outreach text with as-needed follow-up during the first 12 months of living with HIV. Implementation of the interactive text-based intervention used a 'ticket system' to monitor and document responses to texted check-ins and PC follow-up. Using this tracking system, we characterized the 1521 tickets generated during the China-MP3 intervention across 184 intervention participants. A wide variety of topics were the focus of interactions prompted by texted outreach although most appeared to focus on issues related to ART and CD4 and viral load. Almost all participants engaged in at least one SMS-related discussion. Sending regular check-ins may offer unique opportunities to newly diagnosed MSM to ask questions or gather support between face-to-face visits. PMID- 30288684 TI - The Depression Treatment Cascade: Disparities by Alcohol Use, Drug Use, and Panic Symptoms Among Patients in Routine HIV Care in the United States. AB - Little is known about disparities in depression prevalence, treatment, and remission by psychiatric comorbidities and substance use among persons living with HIV (PLWH). We conducted a cross-sectional analysis in a large cohort of PLWH in routine care and analyzed conditional probabilities of having an indication for depression treatment, receiving treatment, receiving indicated treatment adjustments, and achieving remission, stratified by alcohol use, illicit drug use, and panic symptoms. Overall, 34.7% (95% CI 33.9-35.5%) of participants had an indication for depression treatment and of these, 55.3% (53.8 56.8%) were receiving antidepressants. Among patients receiving antidepressants, 33.0% (31.1-34.9%) had evidence of remitted depression. In a subsample of sites with antidepressant dosage data, only 8.8% (6.7-11.5%) of patients received an indicated treatment adjustment. Current drug users (45.8%, 95% CI 43.6-48.1%) and patients reporting full symptoms of panic disorder (75.0%, 95% CI 72.9-77.1%) were most likely to have an indication for antidepressant treatment, least likely to receive treatment given an indication (current drug use: 47.6%, 95% CI 44.3 51.0%; full panic symptoms: 50.8%, 95% CI 48.0-53.6%), or have evidence of remitted depression when treated (22.3%, 95% CI 18.5-26.6%; and 7.3%, 95% CI 5.5 9.6%, respectively). In a multivariable model, drug use and panic symptoms were independently associated with poorer outcomes along the depression treatment cascade. Few differences were evident by alcohol use. Current drug users were most likely to have an indication for depression treatment, but were least likely to be receiving treatment or to have remitted depression. These same disparities were even more starkly evident among patients with co-occurring symptoms of panic disorder compared to those without. Achieving improvements in the depression treatment cascade will likely require attention to substance use and psychiatric comorbidities.

AB - INTRODUCTION: To investigate treatment outcomes after switching from ranibizumab to aflibercept intravitreal injections in patients with macular oedema (MO) secondary to branch retinal vein occlusion (BRVO). METHODS: Eligible patients with refractory MO secondary to BRVO, post treatment with a minimum of three intravitreal injections of ranibizumab at 4-weekly intervals were recruited. Suboptimal or non-responders were defined as patients who had persistent intraretinal fluid (< 75% decrease from baseline) despite a minimum of three consecutive injections. These patients were switched to aflibercept injections on an as-needed basis. The primary study outcomes assessed trends in best-corrected distance visual acuity (BCVA) and central retinal thickness (CRT). To compare means of BCVA and CRT, a paired t test two-tailed with a level of significance set at 0.05 was used. Pearson correlation coefficient was also applied to demonstrate correlation. Participants were followed up for a period of 24 weeks after switching. RESULTS: Thirty-eight eyes of 38 patients were included in the study. Patients had an average of 8.37 ranibizumab intravitreal injections over a mean period of 12 months presenting suboptimal or no response. A significant decrease of mean CRT from 388.63 +/- 93.4 MUm to 290.29 +/- 93.5 MUm (p < 0.001) and an improvement in mean BCVA from logMAR 0.66 +/- 0.38 to logMAR 0.57 +/- 0.27 (p = 0.025) was achieved after an average of 2.27 aflibercept injections. CONCLUSIONS: Given the spectrum of therapies available to date for the management of MO secondary to BRVO, aflibercept appears to be an effective treatment option in cases refractory to ranibizumab. This study based on a small cohort of patients indicates that satisfactory results on retinal anatomy and visual outcomes can be accomplished with a smaller number of injections. Larger-scale studies are needed to extrapolate these promising results. PMID- 30288686 TI - One mirror effect: The regularities of recognition memory. AB - The mirror effect is a pattern of results generally found in two-condition recognition memory experiments that is consistent with normative signal detection theory as a model of recognition. However, the claim has been made that there is a distinct mirror effect, the "strength mirror effect," that differs from the normative one. This claim is based on experiments on recognition memory in which repetition or study time is varied to produce differences in accuracy, where typically the ordinary mirror effect pattern is absent. If this claim is correct, it has major implications for theories of recognition memory. Therefore, a full examination of the data that support the claim was called for. To do that, we replicated the basic demonstration of the no-mirror-effect data and analyzed it further in a series of experiments. The analysis showed the following: (1) Whether or not the mirror effect occurs is determined by whether the experimenter furnishes effective discriminanda that distinguish the weak and strong conditions for the participant. (2) Once Finding 1 is taken into account, no adjustments of or additions to the normative signal detection theory explanations are necessary. (3) There is only one mirror effect, and no separate "strength mirror effect."

AB - Considering bioethanol production, extensive research has been performed to decrease inhibitors produced during pretreatments, to diminish energy input, and to decrease costs. In this study, sugarcane bagasse was pretreated with NaOH, H2SO4, and water. The higher concentration of phenols, 3.3 g/L, was observed in biomass liquid fraction after alkaline pretreatment. Acid pretreatment was responsible to release considerable acetic acid concentration, 2.3 g/L, while water-based pretreatment was the only to release formic acid, 0.02 g/L. Furans derivatives were not detected in liquid fractions regardless of pretreatment. Furthermore, washing step removed most of the phenols from pretreated sugarcane bagasse. Saccharification of alkali-pretreated biomass plus polyethylene glycol (PEG) at 0.4% (w/v) enhanced 8 and 26% the glucose and the xylose release, respectively, while polyvinylpyrrolidone (PVP) also at 0.4% (w/v) increased the release by 10 and 31% of these sugars, respectively, even without washing and filtration steps. Moreover, these polymers cause above 50% activation of endoglucanase and xylanase activities which are crucial for biomass hydrolysis. PMID- 30288688 TI - Association of CILP, COL9A2 and MMP3 Gene Polymorphisms with Lumbar Disc Degeneration in an Indian Population. AB - Lumbar disc degeneration (LDD) is a multifactorial disorder caused by genetic and environmental factors. Polymorphisms in several structural and inflammatory genes like collagens, aggrecan, matrix metalloproteinases are associated with the risk of disc degeneration. In this study, we analyzed the role of a few important single nucleotide polymorphisms in cartilage intermediate layer protein (CILP), collagen 9A2 (COL9A2) and matrix metalloproteinase 3 (MMP3) genes in LDD from an Indian population. Two hundred patients with LDD and 200 healthy controls were recruited for the study. Genotyping was performed by allelic discrimination assay. The rs2073711 polymorphism (CILP gene - GG genotype) was associated with reduced risk of LDD in the Indian population (OR = 0.43, p = 0.016). The rs591058 polymorphism (MMP3 gene - TT genotype) is found to be associated with lower risk among women (OR = 0.34, p = 0.041). No significant association was found between COL9A2 polymorphism rs7533552 and the risk of LDD. We conclude that the CILP gene polymorphism (rs2073711) is associated with a lower risk of LDD, the MMP3 (rs591058) gene polymorphism is associated with LDD among women, and the TT genotype confers a lower risk of LDD. PMID- 30288690 TI - Feature-based attention across saccades: Pop-out in color search is spatiotopic. AB - Our perception of the world remains stable despite the retinal shifts that occur with each saccade. The role of spatial attention in matching pre- to postsaccadic visual information has been well established, but the role of feature-based attention remains unclear. In this study, we examined the transsaccadic processing of a color pop-out target. Participants made a saccade towards a neutral target and performed a search task on a peripheral array presented once the saccade landed. A similar array was presented just before the saccade and we analyzed what aspect of this preview benefitted the postsaccadic search task. We assessed the preview effect in the spatiotopic and retinotopic reference frames, and the potential transfer of feature selectivity across the saccade. In the first experiment, the target and distractor colors remained identical for the preview and the postsaccadic array and performance improved. The largest benefit was observed at the spatiotopic location. In the second experiment, the target and distractor colors were swapped across the saccade. All responses were slowed but the cost was least at the spatiotopic location. Our results show that the preview attracted spatial attention to the target location, which was then remapped, and suggest that previewed features, specifically colors, were transferred across the saccade. Furthermore, the preview induced a spatiotopic advantage regardless of whether the target switched color or not, suggesting that spatiotopy was established independently of feature processing. Our results support independent priming effects of features versus location and underline the role of feature-based selection in visual stability. PMID- 30288689 TI - Agaricus bisporus supplementation reduces high-fat diet-induced body weight gain and fatty liver development. AB - Obesity is a global epidemic characterized not only by excessive fat deposition but also by important complications such as nonalcoholic liver steatosis. Beneficial antiobesogenic effects have been described for some mushrooms. The current study aimed to demonstrate the protective effect of Agaricus bisporus (AB) supplementation against the metabolic alterations induced by high-fat-diet (HFD) feeding. Eight-week-old C57BL/6J mice were fed for 10 weeks with one of the following diets: (1) control diet (n = 7), (2) HFD (n = 7), (3) HFD supplemented with 5% AB (n = 9), and (4) HFD supplemented with 10% AB (n = 9). A pair-fed group was also included for the 10% AB group (n = 6). The impact of AB supplementation on food intake, body weight gain, and liver and fat pad weights was examined. Biochemical, histological, and molecular parameters were also analyzed. Dietary supplementation with 10% AB reduced the HFD-induced increase in body, epididymal, and mesenteric fat weights (p < 0.01, p < 0.05, and p < 0.05, respectively). Supplementation with AB also reduced liver damage in a dose dependent manner (p < 0.01 and p < 0.001). This effect was confirmed by histological analysis that showed that liver steatosis was markedly reduced in mice fed with AB. The beneficial properties of 10% AB supplementation appear to be mediated through a decrease in food intake and via stimulation of mesenteric and hepatic free-fatty acid beta-oxidation, along with a decrease in epidydimal and hepatic expression of CD36. In conclusion, supplementation with AB prevents excessive body weight gain and liver steatosis induced by HFD consumption. PMID- 30288691 TI - Surgical Management of Gastroesophageal Reflux Disease in Patients with Severe Esophageal Dysmotility. AB - BACKGROUND: Gastroesophageal reflux disease (GERD) and esophageal dysmotility are often disqualifying criteria for fundoplication due to dysphagia complications. A tailored partial fundoplication may improve GERD in patients with severe esophageal motility disorders. We evaluate this approach on GERD improvement in non-achalasia esophageal dysmotility patients. METHODS: A single-institution prospective database was reviewed (2007-2016), with inclusion criteria of GERD, previous diagnosis of non-achalasia esophageal motility disorder, and laparoscopic partial fundoplication. Diagnosis of previous achalasia diagnosis or diffused esophageal spasm was excluded. Motility studies, pre- and post-upper gastrointestinal imaging (UGI), esophageal symptom scores, antacid, and PPI use were collected pre-op, 6 months, 12 months, and long-term (LT). Statistical analysis was made using SPSS v.23.0.0, alpha = 0.05. RESULTS: Fifty-two patients met the inclusion criteria. A total of 17.3% had esophageal body amotility, 79.6% had severe esophageal dysmotility. A total of 65.9% women (mean age 64 +/- 15.7), mean peristalsis 45.3 +/- 32.6%, and failed peristalsis 36.0 +/- 32.2%. Mean LES residual pressure was 15.0 +/- 18.0 mmHg, and 40.7% had hypotensive LES. Mean follow-up time was 25 months [1-7 years], with significant improvement in symptoms and reduction in PPI and antacid use at all time-points compared to pre op. A total of 74% had UGI studies at 12 months; all showed persistent dysmotility. Six patients had radiographic hiatal hernia recurrence, with only one being clinically symptomatic postoperatively. Three required dilation for persistent dysphagia. CONCLUSIONS: A tailored partial fundoplication may be effective in symptom relief for non-achalasia patients with esophageal motility disorders and GERD. Significant symptom improvement, low HHR, and PPI use clearly indicate this approach to be effective for this population. PMID- 30288692 TI - Abdominal Aortic Aneurysm Volumetric Evaluation During Mid-term Follow-Up After Endovascular Sealing Using the NellixTM Device. AB - OBJECTIVES: To analyze the volumetric evolution of abdominal aortic aneurysms after endovascular sealing (EVAS) with the NellixTM device during follow-up. METHODS: Patients who underwent elective EVAS in our institution in 2014 and 2015 were retrospectively reviewed. Preoperative, postoperative and 1-year scans were processed. A custom software was conceived to assess semi-automated measurements of the aneurysm sac and the endograft sizes including volume, maximum diameter, sectional area and perimeter. Thrombus volume, aneurysm length, mean distance between the stents inside the polymer-filled sacs and endograft migration were also estimated. Manual maximum diameters were measured for comparison. Inter and intra-observer variability of the proposed semi-automated method was evaluated. RESULTS: Pre-EVAS, post-EVAS and last follow-up scans of 12 patients were finally analyzed during a mean follow-up of 17 +/- 5 months. No endograft migration or endoleak were detected. During follow-up, aneurysm volume and perimeter slightly increased compared to post-EVAS scans (+ 1 and + 5%, respectively, p < 0.05). A systematic 6% enlargement of the endobag volume was also observed (range 1-15 mL, p < 0.001). Endobag maximum diameter, area and perimeter increased 4, 8, and 8%, respectively (all p < 0.01). Mean plane-by-plane distance between stents increased 4% (p < 0.05). Mean thrombus volume did not change during follow-up, although a high variability was observed. Aneurysm and thrombus volume changes were highly correlated (r = 0.93, p < 0.001). No associations were observed between aneurysm and endobag volume changes. Intra- and inter-observer variability was below 1.7 and 2.4% for diameter and volume measurements, respectively. The automated measurements of post-EVAS aneurysm diameter and volume were higher than preoperative (p < 0.05). Maximum diameters measured manually did not differ between scans. CONCLUSION: Small aneurysm volume enlargement detected during a mid-term follow-up was associated with thrombus size change, whereas systematic endograft expansion resulted independent from the aortic growth. Volumetric measurements using a semi-automated method could quantify small changes in aneurysm, endograft and thrombus sizes not detected by manually defined maximal diameters. PMID- 30288693 TI - Early ileostomy reversal after minimally invasive surgery and ERAS program for mid and low rectal cancer. AB - Diverting loop ileostomy following low anterior resection (LAR) is known to decrease quality of life and prolongs the return back to patients' baseline activity. The aim of this retrospective study was to explore feasibility and safety of an early ileostomy reversal strategy in a cohort of patients undergoing minimally invasive LAR within an enhanced recovery after surgery (ERAS) program. Prospectively collected data from 15 patients who underwent minimally invasive LAR and diverting ileostomy at the Division of General and Hepatobiliary Surgery, University of Verona Hospital Trust between September 2015 and December 2016 were retrospectively analyzed. Of 15 patients, 10 patients underwent laparoscopic LAR and 5 patients a robot-assisted procedure. Post-operative complications were observed in 5 patients. Four patients suffered Clavien-Dindo grade 1 or 2 complications, and one patient required redo surgery due to bowel obstruction at the ileostomy site (grade 3b). Following ileostomy reversal, 10 out of 15 patients experienced complications. Two patients required redo surgery for bowel obstruction (grade 3b), whilst eight patients suffered grade 1 or 2 complications, being surgical site infection the most frequently observed (6 cases). Despite that, 80% of patients had their ileostomy reversed within 30 days and median time from initial surgery to ileostomy reversal was 22 days (range 10 150). Early ileostomy closure after minimally invasive LAR and ERAS program is feasible although it carries non-negligible risk of severe complications which, however, does not hinder its accomplishment. PMID- 30288694 TI - Neuron-Type Specific Loss of CDKL5 Leads to Alterations in mTOR Signaling and Synaptic Markers. AB - CDKL5 disorder is a devastating neurodevelopmental disorder associated with epilepsy, developmental retardation, autism, and related phenotypes. Mutations in the CDKL5 gene, encoding CDKL5, have been identified in this disorder. CDKL5 is a protein with homology to the serine-threonine kinases and incompletely characterized function. We generated and validated a murine model bearing a floxed allele of CDKL5 and polyclonal antibodies to CDKL5. CDKL5 is well expressed in the cortex, hippocampus, and striatum, localized to synaptosomes and nuclei and developmentally regulated in the hippocampus. Using Cre-mediated mechanisms, we deleted CDKL5 from excitatory CaMKIIalpha-positive neurons or inhibitory GABAergic neurons. Our data indicate that loss of CDKL5 in excitatory neurons of the cortex or inhibitory neurons of the striatum differentially alters expression of some components of the mechanistic target of rapamycin (mTOR) signaling pathway. Further loss of CDKL5 in excitatory neurons of the cortex or inhibitory neurons of the striatum leads to alterations in levels of synaptic markers in a neuron-type specific manner. Taken together, these data support a model in which loss of CDKL5 alters mTOR signaling and synaptic compositions in a neuron-type specific manner and suggest that CDKL5 may have distinct functional roles related to cellular signaling in excitatory and inhibitory neurons. Thus, these studies provide new insights into the biology of CDKL5 and suggest that the molecular pathology in CDKL5 disorder may have distinct neuron-type specific origins and effects. PMID- 30288695 TI - Cortical Excitability and Activation of TrkB Signaling During Rebound Slow Oscillations Are Critical for Rapid Antidepressant Responses. AB - Rapid antidepressant effects of ketamine become most evident when its psychotomimetic effects subside, but the neurobiological basis of this "lag" remains unclear. Laughing gas (N2O), another NMDA-R (N-methyl-D-aspartate receptor) blocker, has been reported to bring antidepressant effects rapidly upon drug discontinuation. We took advantage of the exceptional pharmacokinetic properties of N2O to investigate EEG (electroencephalogram) alterations and molecular determinants of antidepressant actions during and immediately after NMDA-R blockade. Effects of the drugs on brain activity were investigated in C57BL/6 mice using quantitative EEG recordings. Western blot and qPCR were used for molecular analyses. Learned helplessness (LH) was used to assess antidepressant-like behavior. Immediate-early genes (e.g., bdnf) and phosphorylation of mitogen-activated protein kinase-markers of neuronal excitability-were upregulated during N2O exposure. Notably, phosphorylation of BDNF receptor TrkB and GSK3beta (glycogen synthase kinase 3beta) became regulated only gradually upon N2O discontinuation, during a brain state dominated by slow EEG activity. Subanesthetic ketamine and flurothyl-induced convulsions (reminiscent of electroconvulsive therapy) also evoked slow oscillations when their acute pharmacological effects subsided. The correlation between ongoing slow EEG oscillations and TrkB-GSK3beta signaling was further strengthened utilizing medetomidine, a hypnotic-sedative agent that facilitates slow oscillations directly through the activation of alpha2-adrenergic autoreceptors. Medetomidine did not, however, facilitate markers of neuronal excitability or produce antidepressant-like behavioral changes in LH. Our results support a hypothesis that transient cortical excitability and the subsequent regulation of TrkB and GSK3beta signaling during homeostatic emergence of slow oscillations are critical components for rapid antidepressant responses. PMID- 30288696 TI - Early Manifestations of Brain Aging in Mice Due to Low Dietary Folate and Mild MTHFR Deficiency. AB - Folate is an important B vitamin required for methylation reactions, nucleotide and neurotransmitter synthesis, and maintenance of homocysteine at nontoxic levels. Its metabolism is tightly linked to that of choline, a precursor to acetylcholine and membrane phospholipids. Low folate intake and genetic variants in folate metabolism, such as the methylenetetrahydrofolate reductase (MTHFR) 677 C>T polymorphism, have been suggested to impact brain function and increase the risk for cognitive decline and late-onset Alzheimer's disease. Our study aimed to assess the impact of genetic and nutritional disturbances in folate metabolism, and their potential interaction, on features of cognitive decline and brain biochemistry in a mouse model. Wild-type and Mthfr+/- mice, a model for the MTHFR 677 C>T polymorphism, were fed control or folate-deficient diets from weaning until 8 and 10 months of age. We observed short-term memory impairment measured by the novel object paradigm, altered transcriptional levels of synaptic markers and epigenetic enzymes, as well as impaired choline metabolism due to the Mthfr+/ genotype in cortex or hippocampus. We also detected changes in mRNA levels of Presenillin-1, neurotrophic factors, one-carbon metabolic and epigenetic enzymes, as well as reduced levels of S-adenosylmethionine and acetylcholine, due to the folate-deficient diet. These findings shed further insights into the mechanisms by which genetic and dietary folate metabolic disturbances increase the risk for cognitive decline and suggest that these mechanisms are distinct. PMID- 30288697 TI - Inhibition of Autophagy by Captopril Attenuates Prion Peptide-Mediated Neuronal Apoptosis via AMPK Activation. AB - Accumulation of prion protein (PrPc) into a protease-resistant form (PrPsc) in the brains of humans and animals affects the central nervous system. PrPsc occurs only in mammals with transmissible prion diseases. Prion protein refers to either the infectious pathogen itself or the main component of the pathogen. Recent studies suggest that autophagy is one of the major functions that keep cells alive and which has a protective effect against neurodegeneration. In this study, we investigated whether the anti-hypertensive drug, captopril, could attenuate prion peptide PrP (106-126)-induced calcium alteration-mediated neurotoxicity. Treatment with captopril increased both LC3-II (microtubule-associated protein 1A/1B-light chain 3-II) and p62 protein levels, indicating autophagy flux inhibition. Electron microscopy confirmed the occurrence of autophagic flux inhibition in neuronal cells treated with captopril. Captopril attenuated PrP (106-126)-induced neuronal cell death via AMPK activation and autophagy inhibition. Compound C suppressed AMPK activation as well as the neuroprotective effects of captopril. Thus, these data showed that an anti-hypertensive drug has a protective effect against prion-mediated neuronal cell death via autophagy inhibition and AMPK activation, and also suggest that anti-hypertensive drugs may be effective therapeutic agents against neurodegenerative disorders, including prion diseases. PMID- 30288698 TI - A robust method for segmenting pectoral muscle in mediolateral oblique (MLO) mammograms. AB - PURPOSE: Accurately detecting and removing pectoral muscle areas depicting on mediolateral oblique (MLO) view mammograms are an important step to develop a computer-aided detection scheme to assess global mammographic density or tissue patterns. This study aims to develop and test a new fully automated, accurate and robust method for segmenting pectoral muscle in MLO mammograms. METHODS: The new method includes the following steps. First, a small rectangular region in the top left corner of the MLO mammogram which may contain pectoral muscle is captured and enhanced by the fractional differential method. Next, an improved iterative threshold method is applied to segment a rough binary boundary of the pectoral muscle in the small region. Then, a rough contour is fitted with the least squares method on the basis of points of the rough boundary. Last, the fitting contour is subjected to local active contour evolution to obtain the final pectoral muscle segmentation line. The method has been tested on 720 MLO mammograms. RESULTS: The segmentation results generated using the new scheme were evaluated by two expert mammographic radiologists using a 5-scale rating system. More than 65% were rated above scale 3. When assessing the segmentation results generated using Hough transform, morphologic thresholding methods and Unet-based model, less than 20%, 35% and 47% of segmentation results were rated above scale 3 by two radiologists, respectively. Quantitative data analysis results show that the Dice coefficient of 0.986 +/- 0.005 is obtained. In addition, the mean rate of errors and Hausdorff distance between the contours detected by automated and manual segmentation are FP = 1.71 +/- 3.82%, FN = 5.20 +/- 3.94% and 2.75 +/- 1.39 mm separately. CONCLUSION: The proposed method can be used to segment the pectoral muscle in MLO mammograms with higher accuracy and robustness. PMID- 30288699 TI - Conditions for reliable grip force and jaw angle estimation of da Vinci surgical tools. AB - PURPOSE: This work presents an estimation technique as well as corresponding conditions which are necessary to produce an accurate estimate of grip force and jaw angle on a da Vinci surgical tool using back-end sensors alone. METHODS: This work utilizes an artificial neural network as the regression estimator on a dataset acquired from custom hardware on the proximal and distal ends. Through a series of experiments, we test the effect of estimation accuracy due to change in operating frequency, using the opposite jaw, and using different tools. A case study is then presented comparing our estimation technique with direct measurements of material response curves on two synthetic tissue surrogates. RESULTS: We establish the following criteria as necessary to produce an accurate estimate: operate within training frequency bounds, use the same side jaw, and use the same tool. Under these criteria, an average root mean square error of 1.04 mN m in grip force and 0.17 degrees in jaw angle is achieved. Additionally, applying these criteria in the case study resulted in direct measurements which fell within the 95% confidence bands of our estimation technique. CONCLUSION: Our estimation technique, along with important training criteria, is presented herein to further improve the literature pertaining to grip force estimation. We propose the training criteria to begin establishing bounds on the applicability of estimation techniques used for grip force estimation for eventual translation into clinical practice. PMID- 30288700 TI - Intravitreal Ranibizumab Therapy for Diabetic Macular Edema in Routine Practice: Two-Year Real-Life Data from a Non-interventional, Multicenter Study in Germany. AB - INTRODUCTION: The prospective, non-interventional OCEAN study examined the use of intravitreal ranibizumab injections for the treatment of diabetic macular oedema (DME) in a real-world setting in Germany. METHODS: Adults with DME receiving >= 1 ranibizumab (0.5 mg) injections were recruited by 250 ophthalmologists. Best corrected visual acuity (VA) testing, imaging and treatments were performed according to the investigators' routine practice and documented over 24 months. RESULTS: The full analysis set included 1226 participants. Mean baseline VA was 60.6 [95% CI: 59.7; 61.5] Early Treatment Diabetic Retinopathy Study letters. VA improved by >= 15 letters in 21.5% and 23.5% of the participants at 12 months and 24 months, respectively. They received a mean number of 4.42 [95% CI: 4.30; 4.54] injections in the first year and 5.52 [95% CI: 5.32; 5.73] injections over 24 months, which was markedly lower than in clinical trials. Only 33.4% of the participants received an upload with four initial monthly injections as recommended by the German ophthalmologic societies. Time-to-event analyses that account for missing data inherent to a non-interventional study design demonstrated that participants receiving >= 7 injections in the first year had a faster response, but the duration of the response was shorter compared to the subgroups receiving 1-3 and 4-6 injections. Serious adverse events were reported for 143/1250 (11.4%) participants in the safety population. CONCLUSION: Under treatment is a major problem of DME anti- vascular endothelial growth factor therapy under real life conditions. Despite fewer injections given compared to randomised controlled trials with a consequently reduced overall mean visual gain, a profound functional improvement (>= 15 letters) was achieved over 2 years in 23.5% of eyes with DME. TRIAL REGISTRATION NUMBER: NCT02194803, ClinicalTrials.gov. FUNDING: Novartis Pharma GmbH, Nuremberg, Germany. PMID- 30288701 TI - Gene Regulatory Networks Mediating Cold Acclimation: The CBF Pathway. AB - Under low nonfreezing temperature conditions, plants from temperate climates undergo physiological and biochemical adjustments that increase their tolerance to freezing temperatures. This response, termed cold acclimation, is largely regulated by changes in gene expression. Molecular and genetic studies have identified a small family of transcription factors, called C-repeat binding factors (CBFs), as key regulators of the transcriptomic rearrangement that leads to cold acclimation. The function of these proteins is tightly controlled, and an inadequate supply of CBF activity may be detrimental to the plant. Accumulated evidence has revealed an extremely intricate network of positive and negative regulators of cold acclimation that coalesce at the level of CBF promoters constituting a central hub where multiple internal and external signals are integrated. Moreover, CBF expression is also controlled at posttranscriptional and posttranslational levels further refining CBF regulation. Recently, natural variation studies in Arabidopsis have demonstrated that mutations resulting in changes in CBF expression have an adaptive value for wild populations. Intriguingly, CBF genes are also present in plant species that do not cold acclimate, which suggest that they may also have additional functions. For instance, CBFs are required for some cold-related abiotic stress responses. In addition, their involvement in plant development deserves further study. Although more studies are necessary to fully harness CBF biotechnological potential, these transcription factors are meant to be key for a rational design of crops with enhanced tolerance to abiotic stress. PMID- 30288702 TI - RNA Regulation in Plant Cold Stress Response. AB - In addition to plants, all organisms react to environmental stimuli via the perception of signals and subsequently respond through alterations of gene expression. However, genes/mRNAs are usually not the functional unit themselves, and instead, resultant protein products with individual functions result in various acquired phenotypes. In order to fully characterize the adaptive responses of plants to environmental stimuli, it is essential to determine the level of proteins, in addition to the regulation of mRNA expression. This regulatory step, which is referred to as "mRNA posttranscriptional regulation," occurs subsequent to mRNA transcription and prior to translation. Although these RNA regulatory mechanisms have been well-studied in many organisms, including plants, it is not fully understood how plants respond to environmental stimuli, such as cold stress, via these RNA regulations.A recent study described several RNA regulatory factors in relation to environmental stress responses, including plant cold stress tolerance. In this chapter, the functions of RNA regulatory factors and comprehensive analyses related to the RNA regulations involved in cold stress response are summarized, such as mRNA maturation, including capping, splicing, polyadenylation of mRNA, and the quality control system of mRNA; mRNA degradation, including the decapping step; and mRNA stabilization. In addition, the putative roles of messenger ribonucleoprotein (mRNP) granules, such as processing bodies (PBs) and stress granules (SGs), which are cytoplasmic particles, are described in relation to RNA regulations under stress conditions. These RNA regulatory systems are important for adjusting or fine-tuning and determining the final levels of mRNAs and proteins in order to adapt or respond to environmental stresses. Collectively, these new areas of study revealed that plants possess precise novel regulatory mechanisms which specifically function in the response to cold stress. PMID- 30288703 TI - The Mechanism Enabling Hibernation in Mammals. AB - Some rodents including squirrels and hamsters undergo hibernation. During hibernation, body temperature drops to only a few degrees above ambient temperature. The suppression of whole-body energy expenditure is associated with regulated, but not passive, reduction of cellular metabolism. The heart retains the ability to beat constantly, although body temperature drops to less than 10 degrees C during hibernation. Cardiac myocytes of hibernating mammals are characterized by reduced Ca2+ entry into the cell membrane and a concomitant enhancement of Ca2+ release from and reuptake by the sarcoplasmic reticulum. These adaptive changes would help in preventing excessive Ca2+ entry and its overload and in maintaining the resting levels of intracellular Ca2+. Adaptive changes in gene expression in the heart prior to hibernation may be indispensable for acquiring cold resistance. In addition, protective effects of cold-shock proteins are thought to have an important role. We recently reported the unique expression pattern of cold-inducible RNA-binding protein (CIRP) in the hearts of hibernating hamsters. The CIRP mRNA is constitutively expressed in the heart of a nonhibernating euthermic hamster with several different forms probably due to alternative splicing. The short product contained the complete open reading frame for full-length CIRP, while the long product had inserted sequences containing a stop codon, suggesting production of a C-terminal deletion isoform of CIRP. In contrast to nonhibernating hamsters, only the short product was found in hibernating animals. Thus, these results indicate that CIRP expression in the hamster heart is regulated at the level of alternative splicing, which would permit a rapid increment of functional CIRP when entering hibernation. We will summarize the current understanding of the cold-resistant property of the heart in hibernating animals. PMID- 30288704 TI - Freezing Tolerance of Plant Cells: From the Aspect of Plasma Membrane and Microdomain. AB - Freezing stress is accompanied by a state change from water to ice and has multiple facets causing dehydration; consequently, hyperosmotic and mechanical stresses coupled with unfavorable chilling stress act in a parallel way. Freezing tolerance varies widely among plant species, and, for example, most temperate plants can overcome deleterious effects caused by freezing temperatures in winter. Destabilization and dysfunction of the plasma membrane are tightly linked to freezing injury of plant cells. Plant freezing tolerance increases upon exposure to nonfreezing low temperatures (cold acclimation). Recent studies have unveiled pleiotropic responses of plasma membrane lipids and proteins to cold acclimation. In addition, advanced techniques have given new insights into plasma membrane structural non-homogeneity, namely, microdomains. This chapter describes physiological implications of plasma membrane responses enhancing freezing tolerance during cold acclimation, with a focus on microdomains. PMID- 30288705 TI - Natural Variation in Freezing Tolerance and Cold Acclimation Response in Arabidopsis thaliana and Related Species. AB - During low-temperature exposure, temperate plant species increase their freezing tolerance in a process termed cold acclimation. The molecular mechanisms involved in cold acclimation have been mostly investigated in Arabidopsis thaliana. In addition, other Brassicaceae species related to A. thaliana have been employed in recent years to study plant stress responses on a phylogenetically broader basis and in some cases with extremophile species with a much higher stress tolerance. In this paper, we briefly summarize cold acclimation responses in A. thaliana and current knowledge about cold acclimation in A. thaliana relatives with special emphasis on Eutrema salsugineum and two closely related Thellungiella species. We then present a transcriptomic and metabolomic analysis of cold acclimation in five A. thaliana and two E. salsugineum accessions that differ widely in their freezing tolerance. Differences in the cold responses of the two species are discussed. PMID- 30288706 TI - Ice Nucleation Activity in Plants: The Distribution, Characterization, and Their Roles in Cold Hardiness Mechanisms. AB - Control of freezing in plant tissues is a key issue in cold hardiness mechanisms. Yet freeze-regulation mechanisms remain mostly unexplored. Among them, ice nucleation activity (INA) is a primary factor involved in the initiation and regulation of freezing events in plant tissues, yet the details remain poorly understood. To address this, we developed a highly reproducible assay for determining plant tissue INA and noninvasive freeze visualization tools using MRI and infrared thermography. The results of visualization studies on plant freezing behaviors and INA survey of over 600 species tissues show that (1) freezing sensitive plants tend to have low INA in their tissues (thus tend to transiently supercool), while wintering cold-hardy species have high INA in some specialized tissues; and (2) the high INA in cold-hardy tissues likely functions as a freezing sensor to initiate freezing at warm subzero temperatures at appropriate locations and timing, resulting in the induction of tissue-/species-specific freezing behaviors (e.g., extracellular freezing, extraorgan freezing) and the freezing order among tissues: from the primary freeze to the last tissue remaining unfrozen (likely INA level dependent). The spatiotemporal distributions of tissue INA, their characterization, and functional roles are detailed. INA assay principles, anti-nucleation activity (ANA), and freeze visualization tools are also described. PMID- 30288707 TI - Investigating Freezing Patterns in Plants Using Infrared Thermography. AB - Since the discovery of infrared radiation in 1800, the improvement of technology to detect and image infrared (IR) has led to numerous breakthroughs in several scientific fields of study. The principle that heat is released when water freezes and the ability to image this release of heat using IR thermography (IRT) has allowed an unprecedented understanding of freezing in plants. Since the first published report of the use of IRT to study freezing in plants, numerous informative discoveries have been reported. Examples include barriers to freezing, specific sites of ice nucleation, direction and speed of ice propagation, specific structures that supercool, and temperatures at which they finally freeze. These and other observations underscore the significance of this important technology on plant research. PMID- 30288708 TI - Mechanism of Overwintering in Trees. AB - Boreal trees possess very high freezing resistance, which is induced by short-day length and low temperatures, in order to survive severe subzero temperatures in winter. During autumn, cooperation of photoreceptors and circadian clock system perceiving photoperiod shortening results in growth cessation, dormancy development, and first induction of freezing resistance. The freezing resistance is further enhanced by subsequent low temperature during seasonal cold acclimation with concomitant changes in various morphological and physiological features including accumulation of sugars and late embryogenesis abundant proteins. The mechanism of adaptation to freezing temperatures differs depending on the type of tissue in boreal trees. For example, bark, cambium, and leaf cells tolerate freezing-induced dehydration by extracellular freezing, whereas xylem parenchyma cells avoid intracellular freezing by deep supercooling. In addition, dormant buds in some trees respond by extraorgan freezing. Boreal trees have evolved overwintering mechanisms such as dormancy and high freezing resistance in order to survive freezing temperatures in winter. PMID- 30288709 TI - The Mechanism of Low-Temperature Tolerance in Fish. AB - In this chapter, we cover the life history of fish in low-temperature environments, including their overwintering behavior and the physiological mechanisms by which they maintain life in cold environments, based on research to date. There is relatively little research on low-temperature tolerance of fish, compared with research on this phenomenon in mammals and birds, which are also vertebrates, and the mechanisms in fish have not been fully elucidated. First, we cover the life history of fish that overwinter by entering dormancy or hibernation. Next, we describe the mechanism that controls body temperature in fish that survive low-temperature environments. Finally, we introduce the physiological mechanisms for survival in extremely low-temperature environments, particularly antifreeze proteins. PMID- 30288710 TI - Mechanisms Underlying Freezing and Desiccation Tolerance in Bryophytes. AB - Bryophytes are small land plants that have many morphological and physiological features different from vascular plants. With distinct water relations of bryophytes, many bryophyte species exhibit high degrees of tolerance to freezing and desiccation. The tolerance is sustained by the constitutive repair mechanism and the inducible mechanism regulated by environmental signals that provoke specific responses within the cells. Bryophyte cells sense changes in environmental conditions such as decreases in osmotic potential and temperature and that some responses are likely to be mediated by the stress hormone, abscisic acid. Due to their simple structures and high degrees of dehydration tolerance, bryophytes are useful for physiological studies on abiotic stress response and also for analysis of signal sensing and transduction of environmental signals. Furthermore, the basal phylogenetic position of bryophytes in land plants provides many insights into the evolutionary events for conquest of land by the ancestors of plants and subsequent diversification of species as well as their survival strategies in the terrestrial environment. PMID- 30288711 TI - Regulatory Gene Networks in Drought Stress Responses and Resistance in Plants. AB - Plant responses to drought stress have been analyzed extensively to reveal complex regulatory gene networks, including the detection of water deficit signals, as well as the physiological, cellular, and molecular responses. Plants recognize water deficit conditions at their roots and transmit this signal to their shoots to synthesize abscisic acid (ABA) in their leaves. ABA is a key phytohormone that regulates physiological and molecular responses to drought stress, such as stomatal closure, gene expression, and the accumulation of osmoprotectants and stress proteins. ABA transporters function as the first step for propagating synthesized ABA. To prevent water loss, ABA influx in guard cells is detected by several protein kinases, such as SnRK2s and MAPKs that regulate stomatal closure. ABA mediates a wide variety of gene expression machineries with stress-responsive transcription factors, including DREBs and AREBs, to acquire drought stress resistance in whole tissues. In this chapter, we summarize recent advances in drought stress signaling, focusing on gene networks in cellular and intercellular stress responses and drought resistance. PMID- 30288712 TI - Mechanism of Stomatal Closure in Plants Exposed to Drought and Cold Stress. AB - Drought is one of the abiotic stresses which impairs the plant growth/development and restricts the yield of many crops throughout the world. Stomatal closure is a common adaptation response of plants to the onset of drought condition. Stomata are microscopic pores on the leaf epidermis, which regulate the transpiration/CO2 uptake by leaves. Stomatal guard cells can sense various abiotic and biotic stress stimuli from the internal and external environment and respond quickly to initiate closure under unfavorable conditions. Stomata also limit the entry of pathogens into leaves, restricting their invasion. Drought is accompanied by the production and/or mobilization of the phytohormone, abscisic acid (ABA), which is well-known for its ability to induce stomatal closure. Apart from the ABA, various other factors that accumulate during drought and affect the stomatal function are plant hormones (auxins, MJ, ethylene, brassinosteroids, and cytokinins), microbial elicitors (salicylic acid, harpin, Flg 22, and chitosan), and polyamines . The role of various signaling components/secondary messengers during stomatal opening or closure has been a matter of intense investigation. Reactive oxygen species (ROS) , nitric oxide (NO) , cytosolic pH, and calcium are some of the well-documented signaling components during stomatal closure. The interrelationship and interactions of these signaling components such as ROS, NO, cytosolic pH, and free Ca2+ are quite complex and need further detailed examination.Low temperatures can have deleterious effects on plants. However, plants evolved protection mechanisms to overcome the impact of this stress. Cold temperature inhibits stomatal opening and causes stomatal closure. Cold acclimated plants often exhibit marked changes in their lipid composition, particularly of the membranes. Cold stress often leads to the accumulation of ABA, besides osmolytes such as glycine betaine and proline. The role of signaling components such as ROS, NO, and Ca2+ during cold acclimation is yet to be established, though the effects of cold stress on plant growth and development are studied extensively. The information on the mitigation processes is quite limited. We have attempted to describe consequences of drought and cold stress in plants, emphasizing stomatal closure. Several of these factors trigger signaling components in roots, shoots, and atmosphere, all leading to stomatal closure. A scheme is presented to show the possible signaling events and their convergence and divergence of action during stomatal closure. The possible directions for future research are discussed. PMID- 30288713 TI - Mechanisms of Maturation and Germination in Crop Seeds Exposed to Environmental Stresses with a Focus on Nutrients, Water Status, and Reactive Oxygen Species. AB - Environmental stresses can reduce crop yield and quality considerably. Plants protect cell metabolism in response to abiotic stresses at all stages of their life cycle, including seed production. As the production of vigorous seeds is important to both yield and crop growth, we analyzed causes of yield loss and reduced grain quality in staple crops exposed to environmental stresses such as drought and temperature extremes, with a focus on the remobilization of nutrients and water status during seed filling. Because water is one of the factors that limit seed development, seeds must have mechanisms that allow them to withstand water loss during seed maturation. In addition, analysis of the effects of reactive oxygen species (ROS) on transcription regulation and signaling should help to elucidate the regulation of seed dormancy and germination. In this review, we focus on nutrient remobilization, water mobility, plant hormones (gibberellins, abscisic acid, and ethylene), and ROS in sink and source organs and describe how rice, wheat, barley, soybean, and cowpea plants control seed maturation and germination under environmental stresses. PMID- 30288714 TI - The Antioxidant System in the Anhydrobiotic Midge as an Essential, Adaptive Mechanism for Desiccation Survival. AB - One of the major damaging factors for living organisms experiencing water insufficiency is oxidative stress. Loss of water causes a dramatic increase in the production of reactive oxygen species (ROS). Thus, the ability for some organisms to survive almost complete desiccation (called anhydrobiosis) is tightly related to the ability to overcome extraordinary oxidative stress. The most complex anhydrobiotic organism known is the larva of the chironomid Polypedilum vanderplanki. Its antioxidant system shows remarkable features, such as an expansion of antioxidant genes, their overexpression, as well as the absence or low expression of enzymes required for the synthesis of ascorbate and glutathione and their antioxidant function. In this chapter, we summarize existing data about the antioxidant system of this insect, which is able to cope with substantial oxidative damage, even in an intracellular environment that is severely disturbed due to water loss. PMID- 30288715 TI - Physicochemical Aspects of the Biological Functions of Trehalose and Group 3 LEA Proteins as Desiccation Protectants. AB - In this review, we first focus on the mechanism by which the larva of the sleeping chironomid, Polypedilum vanderplanki, survives an extremely dehydrated state and describe how trehalose and probably late embryogenesis abundant (LEA) proteins work as desiccation protectants. Second, we summarize the solid-state and solution properties of trehalose and discuss why trehalose works better than other disaccharides as a desiccation protectant. Third, we describe the structure and function of two model peptides based on group 3 LEA proteins after a short introduction of native LEA proteins themselves. Finally, we present our conclusions and a perspective on the application of trehalose and LEA model peptides to the long-term storage of biological materials. PMID- 30288716 TI - Supercooling-Promoting (Anti-ice Nucleation) Substances. AB - Studies on supercooling-promoting substances (SCPSs) are reviewed introducing name of chemicals, experimental conditions and the supercooling capability (SCC) in all, so far recognized, reported SCPSs and results of our original study are presented in order to totally show the functional properties of SCPSs which are known in the present state. Many kinds of substances have been identified as SCPSs that promote supercooling of aqueous solutions in a non-colligative manner by reducing the ice nucleation capability (INC) of ice nucleators (INs). The SCC as revealed by reduction of freezing temperature ( degrees C) by SCPSs differs greatly depending on the INs. While no single SCPS that affects homogeneous ice nucleation to reduce ice nucleation point has been found, many SCPSs have been found to reduce freezing temperatures by heterogeneous ice nucleation with a large fluctuation of SCC depending on the kind of heterogeneous IN. Not only SCPSs increase the degree of SCC ( degrees C), but also some SCPSs have additional SCC to stabilize a supercooling state for a long term to stabilize supercooling against strong mechanical disturbance and to reduce sublimation of ice crystals. The mechanisms underlying the diverse functions of SCPSs remain to be determined in future studies. PMID- 30288718 TI - Development and Application of Cryoprotectants. AB - Cryopreservation involves the preservation of biological materials, including cells, embryos, tissues, and organs, at ultra-low temperatures (in a state of suspended animation), for a long period of time, and in a way that allows them to be restored whenever required. Freezing of biological samples is generally accompanied by numerous undesirable outcomes such as intra- and extracellular freezing damage and osmotic stress. To prevent these adverse effects, cryoprotective agents (CPAs) are added to biological materials before freezing. Over the years, a number of CPAs have been identified and developed and have been employed successfully for numerous applications. Here, we review the history and development of cryoprotectants and the current understanding of the cryopreservation process. We conclude with a discussion about the application of cryopreservation for various clinical and academic studies. PMID- 30288717 TI - Applications of Antifreeze Proteins: Practical Use of the Quality Products from Japanese Fishes. AB - Numerous embryonic ice crystals are generated in water at the moment of freezing. These crystals grow and merge together to form an ice block that can be generally observed. Antifreeze protein (AFP) is capable of binding to the embryonic ice crystals, inhibiting such an ice block formation. Fish-derived AFP additionally binds to membrane lipid bilayers to prolong the lifetime of cells. These unique abilities of AFP have been studied extensively for the development of advanced techniques, such as ice recrystallization inhibitors, freeze-tolerant gels, cell preservation fluids, and high-porosity ceramics, for which mass-preparation method of the quality product of AFP utilizing fish muscle homogenates made a significant contribution. In this chapter, we present both fundamental and advanced information of fish AFPs that have been especially discovered from mid latitude sea area, which will provide a hint to develop more advanced techniques applicable in both medical and industrial fields. PMID- 30288719 TI - Cryopreservation of Plant Genetic Resources. AB - Cryopreservation encompasses several interconnect disciplines including physiology and cryophysics. This chapter reviews the current techniques for cryopreservation of plant genetic resources (PGRs). Vitrification is an effective ice crystal avoidance mechanism for hydrated cells and tissues. With any cryopreservation method, whole or partial parts of specimens which are sufficiently dehydrated can be vitrified by rapid cooling in liquid nitrogen (LN). Techniques discussed are the vitrification protocol, encapsulation vitrification protocol, droplet vitrification protocol (DV), vitrification protocol using cryo-plates (V cryo-plate), and air dehydration protocol using cryo-plates (D cryo-plate). In these DV, V, and D cryo-plate protocols, specimens to be cryopreserved are immersed directly into LN on aluminum foil strips or cryo plates; removal from LN to rewarming solution results in a high level of plant regrowth with ultrarapid cooling and warming. The protocols were applied to a wide array of plant species including wild and multi-ploid species, although fine tuning of the protocols was required for successful application to specific plant species and lines. These three protocols efficiently complement each other and appear highly promising to facilitate large-scale cryobanking of PGRs in genebanks. Cryo-scanning electron microscopy makes it possible to examine the cellular and water behavior in plant tissues when immersed in LN. It has been verified that tissues cryopreserved by the process of vitrification and the cryo plate protocols are cryopreservation methods for reliable long-term preservation of PGRs. PMID- 30288720 TI - Applications of Freezing and Freeze-Drying in Pharmaceutical Formulations. AB - Freeze-drying is a popular method to prepare pharmaceutical formulations containing structurally complex active ingredients and drug delivery system carriers. The solidification performed at lower temperature significantly improves storage stability of proteins, peptides, antibiotics, vaccines, and liposomes, which are marginally stable in aqueous solutions. Individual components of the freeze-drying process (freezing, primary drying, secondary drying), however, expose proteins to various stresses. Certain excipients, including disaccharides (e.g., sucrose, trehalose) and amino acids, can be added to protect the proteins and supramolecular drug delivery systems against physical stress associated with freezing and storage by substituting the molecular interactions provided by water molecules. Some excipients embed the active ingredients in glass-state solids with low molecular mobility, thereby reducing chemical reactivity. Thus, the use of appropriate excipients and process control is important to protect proteins during freeze-drying. This chapter describes the applications of freeze-drying in the pharmaceutical production process, mainly focusing on formulation and process optimization for protein therapeutics. PMID- 30288721 TI - Control of Physical Changes in Food Products. AB - Food is a multicomponent system that mainly comprises protein, carbohydrate, fat, and water. During food processing and preservation, various physical changes (e.g., melting, crystallization, glass transition) occur in food products, affecting their quality. This chapter specifically examines the effect of physical changes on the quality of dry and frozen food products. Dry food products are commonly in an amorphous state. Therefore, glass transition occurs during their dehydration-rehydration processing. To control their texture and physical stability, it is important to elucidate the effects of water contents on the glass transition temperature of dry food products. Frozen foods consist of ice crystals and freeze-concentrated matrix. The formation of ice crystal and the dynamics of ice crystal evolution affect food quality. Therefore control of ice crystals is important for high-quality frozen food. Moreover, because freeze concentrated matrix consists of solute that are plasticized by the unfrozen water and is in an amorphous state, it can undergo glass transition by freeze concentration. The physical state of freeze-concentrated matrix also strongly affects the stability of food quality during frozen storage.

AB - This review of Mammen's new book (2017), provides a brief summary of the first part, stressing the main points of the author's constructive critique of the unfortunate issues psychology inherited from the atomistic mechanism of classical physics. Driving the discussion on the ontological level, Mammen briefly shows how nowadays natural sciences provide the main components psychology needs to overcome the everlasting crisis of psychology since its constitution as a science: discontinuity, contextuality, etc. Making of the relation between subject and object the foundation of any science, Mammen contributes to a new ontology specific to human study with elements of last century mathematics, notably the axiom of choice, bridging the rift between natural and human sciences with a continuum from inert matter to more or less advanced life forms. Mammen's constructive proposal opens the building site of a new foundation for life sciences, avoiding both simplistic mechanism and nihilist post-modernism. PMID- 30288723 TI - Hoop training: a pilot study assessing the effectiveness of a multisensory approach to treatment of body image disturbance in anorexia nervosa. AB - PURPOSE: We tested in a pilot study a new intervention for body image disturbance in anorexia nervosa (AN). Unlike common treatment approaches our hoop training targeted not only cognitive-emotional and visual aspects of body image, but also tactile and body-scaled action components. METHODS: We assessed cognitive, visual, tactile and body-scaled action aspects of body image disturbance before and after completion of hoop training. Twelve AN patients completed treatment as usual (TAU) for body image, 14 completed hoop training in addition to TAU. RESULTS: Results show that patients who completed the 8-week individual hoop training in addition to TAU improved more on body image disturbance tasks from baseline to follow-up than patients who completed only TAU. Hoop training specifically seems to affect tactile body image and body-scaled action. CONCLUSIONS: Taken together, a treatment approach in which the full spectrum of body image disturbances in AN is targeted has a unique added effect over treatment as usual. LEVEL OF EVIDENCE: Level II, non-randomized controlled study. PMID- 30288724 TI - How do you feel when you check your body? Emotional states during a body-checking episode in normal-weight females. AB - PURPOSE: Cognitive-behavioral theories posit that body checking decreases negative emotions, but increases levels of arousal. However, few studies have investigated the effects of body checking on the course of emotional states. Therefore, the current study examined how normal-weight females with higher and lower eating, weight, and shape concerns feel during a checking episode of their most-liked and least-liked body parts. METHODS: In an online design, levels of negative emotions and arousal were retrospectively assessed before, during, immediately after, and 15 min after an individually remembered body-checking episode. Participants (N = 355) also rated their subjective satisfaction with specific body parts. RESULTS: Levels of negative emotions were lower 15 min after the checking episode of most-liked and least-liked body parts than before the episode. However, negative emotions increased during the checking episode of least-liked body parts, but subsided thereafter. The levels of arousal increased during the checking episodes of most-liked and least-liked body parts and decreased afterwards, and females with higher concerns reported greater levels of arousal than females with lower concerns. Furthermore, females with higher concerns reported more body checking than those with lower concerns. CONCLUSIONS: The results support the assumptions of the cognitive-behavioral theories, as body checking led to a decrease in negative emotions in the longer term, and levels of arousal increased during the checking episode. The greater levels of arousal in females with higher concerns, and their pronounced body-checking behavior, might enhance their existing concerns and increase the risk of disordered eating. LEVEL OF EVIDENCE: Level V, descriptive study. PMID- 30288725 TI - Affect, reward, and punishment in anorexia nervosa: a narrative overview. AB - INTRODUCTION: Anorexia nervosa (AN) is a serious psychiatric disorder that is difficult to treat and often follows a protracted course. A number of theoretical models have been proposed for the etiology and maintenance of AN. Two domains that have received substantial attention in the literature on AN are affect and reward/punishment processes. However, despite an overlap in the nature and implications of these processes, studies of AN addressing these constructs have typically investigated them independently. PURPOSE: The purpose of this narrative review is to integrate the literature on the role of affect, reward, and punishment in AN. METHOD: We provide a focused narrative overview of the literature relating to the affect, reward, and punishment in AN via a synthesis of recent reviews and meta-analyses. RESULTS: We first describe several prominent affect and reward/punishment-based conceptualizations of AN, followed by a brief overview of the existing empirical literature in these domains. CONCLUSION: We provide a critical discussion of the disparate nature of these literatures in AN, including associated limitations. We then conclude with an extensive discussion of directions for future research that integrate the study of affect and reward/punishment processes in AN. LEVEL OF EVIDENCE: Level V, narrative review.

PMID- 30288727 TI - Pelvic floor muscle training versus no treatment, or inactive control treatments, for urinary incontinence in women. AB - BACKGROUND: Pelvic floor muscle training (PFMT) is the most commonly used physical therapy treatment for women with stress urinary incontinence (SUI). It is sometimes also recommended for mixed urinary incontinence (MUI) and, less commonly, urgency urinary incontinence (UUI).This is an update of a Cochrane Review first published in 2001 and last updated in 2014. OBJECTIVES: To assess the effects of PFMT for women with urinary incontinence (UI) in comparison to no treatment, placebo or sham treatments, or other inactive control treatments; and summarise the findings of relevant economic evaluations. SEARCH METHODS: We searched the Cochrane Incontinence Specialised Register (searched 12 February 2018), which contains trials identified from CENTRAL, MEDLINE, MEDLINE In Process, MEDLINE Epub Ahead of Print, ClinicalTrials.gov, WHO ICTRP, handsearching of journals and conference proceedings, and the reference lists of relevant articles. SELECTION CRITERIA: Randomised or quasi-randomised controlled trials in women with SUI, UUI or MUI (based on symptoms, signs or urodynamics). One arm of the trial included PFMT. Another arm was a no treatment, placebo, sham or other inactive control treatment arm. DATA COLLECTION AND ANALYSIS: At least two review authors independently assessed trials for eligibility and risk of bias. We extracted and cross-checked data. A third review author resolved disagreements. We processed data as described in the Cochrane Handbook for Systematic Reviews of Interventions. We subgrouped trials by diagnosis of UI. We undertook formal meta-analysis when appropriate. MAIN RESULTS: The review included 31 trials (10 of which were new for this update) involving 1817 women from 14 countries. Overall, trials were of small-to-moderate size, with follow ups generally less than 12 months and many were at moderate risk of bias. There was considerable variation in the intervention's content and duration, study populations and outcome measures. There was only one study of women with MUI and only one study with UUI alone, with no data on cure, cure or improvement, or number of episodes of UI for these subgroups.Symptomatic cure of UI at the end of treatment: compared with no treatment or inactive control treatments, women with SUI who were in the PFMT groups were eight times more likely to report cure (56% versus 6%; risk ratio (RR) 8.38, 95% confidence interval (CI) 3.68 to 19.07; 4 trials, 165 women; high-quality evidence). For women with any type of UI, PFMT groups were five times more likely to report cure (35% versus 6%; RR 5.34, 95% CI 2.78 to 10.26; 3 trials, 290 women; moderate-quality evidence).Symptomatic cure or improvement of UI at the end of treatment: compared with no treatment or inactive control treatments, women with SUI who were in the PFMT groups were six times more likely to report cure or improvement (74% versus 11%; RR 6.33, 95% CI 3.88 to 10.33; 3 trials, 242 women; moderate-quality evidence). For women with any type of UI, PFMT groups were two times more likely to report cure or improvement than women in the control groups (67% versus 29%; RR 2.39, 95% CI 1.64 to 3.47; 2 trials, 166 women; moderate-quality evidence).UI-specific symptoms and quality of life (QoL) at the end of treatment: compared with no treatment or inactive control treatments, women with SUI who were in the PFMT group were more likely to report significant improvement in UI symptoms (7 trials, 376 women; moderate-quality evidence), and to report significant improvement in UI QoL (6 trials, 348 women; low-quality evidence). For any type of UI, women in the PFMT group were more likely to report significant improvement in UI symptoms (1 trial, 121 women; moderate-quality evidence) and to report significant improvement in UI QoL (4 trials, 258 women; moderate-quality evidence). Finally, for women with mixed UI treated with PFMT, there was one small trial (12 women) reporting better QoL.Leakage episodes in 24 hours at the end of treatment: PFMT reduced leakage episodes by one in women with SUI (mean difference (MD) 1.23 lower, 95% CI 1.78 lower to 0.68 lower; 7 trials, 432 women; moderate-quality evidence) and in women with all types of UI (MD 1.00 lower, 95% CI 1.37 lower to 0.64 lower; 4 trials, 349 women; moderate-quality evidence).Leakage on short clinic-based pad tests at the end of treatment: women with SUI in the PFMT groups lost significantly less urine in short (up to one hour) pad tests. The comparison showed considerable heterogeneity but the findings still favoured PFMT when using a random-effects model (MD 9.71 g lower, 95% CI 18.92 lower to 0.50 lower; 4 trials, 185 women; moderate-quality evidence). For women with all types of UI, PFMT groups also reported less urine loss on short pad tests than controls (MD 3.72 g lower, 95% CI 5.46 lower to 1.98 lower; 2 trials, 146 women; moderate-quality evidence).Women in the PFMT group were also more satisfied with treatment and their sexual outcomes were better. Adverse events were rare and, in the two trials that did report any, they were minor. The findings of the review were largely supported by the 'Summary of findings' tables, but most of the evidence was downgraded to moderate on methodological grounds. The exception was 'participant-perceived cure' in women with SUI, which was rated as high quality. AUTHORS' CONCLUSIONS: Based on the data available, we can be confident that PFMT can cure or improve symptoms of SUI and all other types of UI. It may reduce the number of leakage episodes, the quantity of leakage on the short pad tests in the clinic and symptoms on UI specific symptom questionnaires. The authors of the one economic evaluation identified for the Brief Economic Commentary reported that the cost-effectiveness of PFMT looks promising. The findings of the review suggest that PFMT could be included in first-line conservative management programmes for women with UI. The long-term effectiveness and cost-effectiveness of PFMT needs to be further researched. PMID- 30288729 TI - Slavery and institutional morality at Georgetown University: Reply to Nelson. PMID- 30288730 TI - Early parenting predicts hippocampal subregion volume via stress reactivity in childhood. AB - Rodent models indicate that parenting shapes offspring outcomes by programming the hypothalamic-pituitary-adrenal axis response to stress and, ultimately, altering brain structure and function. The present study tested this hypothesis and explored possible timing-dependent associations in a longitudinal sample of children (N = 63). At Time 1 (M = 4.23 +/- 0.84 years) and Time 2 (M = 7.20 +/- 0.89 years), children completed parent-child interaction tasks and a laboratory stressor after which salivary cortisol samples were collected. At Time 2, children also completed a structural MRI. Analyses revealed timing- and region dependent associations between early and concurrent parenting and cortisol reactivity and hippocampal subregion volumes. Moreover, greater negative parenting during early childhood predicted greater cortisol reactivity three years later, which, in turn, led to reduced left hippocampal tail volume. Findings suggest that the hippocampus is sensitive to environmental influences during early childhood, a result that parallels findings from rodent models. PMID- 30288731 TI - Use of intrapartum ultrasound in term pregnant women with contractions before hospital admission. AB - INTRODUCTION: The aim of this study was to test the hypothesis that transperineal ultrasound can be used to decide whether to admit a pregnant woman due to labor. MATERIAL AND METHODS: In this analytical cross-sectional observational study, transperineal ultrasound was performed on pregnant women with intact membranes who came to the hospital due to contractions. A decision was made to admit women due to labor based on the ultrasound measurements. The ultrasound measurements were used to determine cervical dilation, the angle of progression, and fetal head position. The managing midwives were blinded to the results and made the final decision to admit the women based on digital vaginal examination. RESULTS: It was possible to decide whether a woman had to be admitted for delivery or discharged due to the latent phase of labor according to the ultrasound examination in 55 of the 57 cases (96.5%). In 4 of the 55 cases, the decision based on ultrasound differed from the midwife's decision (7.3%). There was strong agreement between the decision to admit the pregnant women based on ultrasound measurements and the digital vaginal examination (Cohen's kappa: 0.844). It was possible to measure cervical dilation with ultrasound in 52 of the 57 cases (91.2%). The intraclass correlation coefficient for the cervical dilation measurements was 0.736 (95% confidence interval 0.539-0.848). CONCLUSIONS: There was strong agreement between the ultrasound and digital vaginal examination results in the decision to admit singleton pregnant women at term due to labor. A large number of vaginal examinations could be avoided by using intrapartum ultrasound. PMID- 30288732 TI - Repetitive neonatal pain and reduced maternal care alter brain neurochemistry. AB - Preterm infants are exposed to many stressors while in the neonatal intensive care unit including pain and reduced maternal care. Both stressors can have a profound negative impact on brain development, and the present study sought to investigate some of the biological mechanisms underlying this phenomenon. Rat pups underwent a series of repetitive needle pokes and/or reduced maternal care through a novel tea-ball infuser encapsulation model during the first four days of life. On postnatal day four, pups were sacrificed and serum was analyzed for corticosterone, while brains were tested for various neurotransmitters and brain metabolites through magnetic resonance spectroscopy. We found that exposure to maternal isolation and neonatal pain produced an increase in serum corticosterone but decreased glutamate levels in the hippocampus and frontal cortex. These alterations in stress responding and neurochemistry in response to the early-life stressors may help explain some of the negative outcomes seen in preterm infants. PMID- 30288733 TI - Interpregnancy interval and abnormally invasive placentation. AB - INTRODUCTION: The presence of a previous uterine scar is a strong risk factor for developing abnormally invasive placentation (AIP). We sought to determine whether a short interpregnancy interval predisposes to AIP. We hypothesized that a short interpregnancy interval after a previous cesarean delivery increases the risk of AIP in comparison with a longer interpregnancy interval. MATERIAL AND METHODS: We performed a retrospective cohort study of women with a histological diagnosis of AIP and a history of a previous cesarean section. Women were included in the control group if they had a previous cesarean section with a placenta underlying the previous uterine scar or an anterior previa. The time interval between pregnancy and AIP data was analyzed using the chi-square test and two-tailed Fisher's exact test. RESULTS: There was no statistical difference in the interpregnancy interval between women who had AIP vs the control group. Gravidity and parity were found to be significantly higher in the women with AIP vs the controls. CONCLUSIONS: These results suggest that a short interpregnancy interval may not increase the risk of developing AIP. PMID- 30288734 TI - Editorial - Maori's women's health in New Zealand.

AB - Biallelic exostosin-2 (EXT2) pathogenic variants have been described as the cause of the Seizures-Scoliosis-Macrocephaly syndrome (OMIM 616682) characterized by intellectual disability, facial dysmorphisms and seizures. More recently, it has been proposed to rename this disorder with the acronym AREXT2 (autosomal recessive EXT2-related syndrome). Here, we report the third family affected by AREXT2 syndrome, harboring compound missense variants in EXT2, p.Asp227Asn, and p.Tyr608Cys. In addition, our patients developed multiple exostoses, which were not observed in the previously described families. AREXT2 syndrome can be considered as a multiorgan Congenital Disorder of Glycosylation caused by a significant, but non-lethal, decrease in EXT2 expression, thereby affecting the synthesis of the heparan sulfate proteoglycans, which is relevant in many physiological processes. Our finding expands the clinical and molecular spectrum of the AREXT2 syndrome and suggests a possible genotype/phenotype correlation in the development of the exostoses. PMID- 30288736 TI - Supraglottic airway devices in difficult airway management: a retrospective cohort study of 658,104 general anaesthetics registered in the Danish Anaesthesia Database. AB - Indications for using supraglottic airway devices have widened over time and they now hold a prominent role in guidelines for difficult airway management. We aimed to describe the use of supraglottic airway devices in difficult airway management. We included adult patients undergoing general anaesthesia registered in the Danish Anaesthesia Database from 2008 to 2012 whose airway management had been recorded as difficult, defined as: >= 3 tracheal intubation attempts; failed tracheal intubation; or difficult facemask ventilation. In the Danish Anaesthesia Database, a separate difficult airway management module requires the technique used in each successive airway management attempt to be recorded. The primary aim of the study was to describe the use of supraglottic airway devices in cases of difficult airway management. Secondary aims were to examine success rates of supraglottic airway devices in difficult airway management cases, and specifically in the cases of 'cannot intubate, cannot facemask ventilate'. Difficult airway management occurred in 4898 (0.74% (95%CI 0.72-0.76%)) of 658,104 records of general anaesthesia. Supraglottic airway devices were used or use was attempted in 607 cases of difficult airway management (12.4% (95%CI 11.5 13.3%)), and were successful in 395 (65.1% (95%CI 61.2-68.8%)) cases. In 'cannot intubate, cannot facemask ventilate' situations, supraglottic airway devices were used in 86 (18.9% (95%CI 15.6-22.8%)) of 455 records and were successful in 54 (62.8% (95%CI 52.2-72.3%)) cases. We found that supraglottic airway devices are not widely used in the management of the difficult airway despite their prominent role in difficult airway management guidelines. PMID- 30288737 TI - The uses of disorder in negotiated information orders: information leveraging and changing norms in global public health governance. AB - The SARS epidemic that broke out in late 2002 in China's Guangdong Province highlighted the difficulties of reliance on state-provided information when states have incentives to conceal discrediting information about public health threats. Using SARS and the International Health Regulations (IHR) as a starting point, this article examines negotiated information orders in global public health governance and the irregularities in the supply of data that underlie them. Negotiated information orders within and among the organizations in a field (here, e.g., the World Health Organization, member states, government agencies, and international non-governmental organizations) spell out relationships among different categories of knowledge and non-knowledge - what is known, acknowledged to be known, and available for use in decision making versus what might be known but cannot be acknowledged or officially used. Through information leveraging, technically sufficient information then becomes socially sufficient information. Thus it is especially information initially categorized as non-knowledge - including suppressed data, rumour, unverified evidence, and unofficial information - that creates pressure for the renegotiation of information orders. The argument and evidence of the article also address broader issues about how international law and global norms are realigned, how global norms change, and how social groups manage risk. PMID- 30288738 TI - Individual-, family-, and school-level interventions targeting multiple risk behaviours in young people. AB - BACKGROUND: Engagement in multiple risk behaviours can have adverse consequences for health during childhood, during adolescence, and later in life, yet little is known about the impact of different types of interventions that target multiple risk behaviours in children and young people, or the differential impact of universal versus targeted approaches. Findings from systematic reviews have been mixed, and effects of these interventions have not been quantitatively estimated. OBJECTIVES: To examine the effects of interventions implemented up to 18 years of age for the primary or secondary prevention of multiple risk behaviours among young people. SEARCH METHODS: We searched 11 databases (Australian Education Index; British Education Index; Campbell Library; Cumulative Index to Nursing and Allied Health Literature (CINAHL); Cochrane Central Register of Controlled Trials (CENTRAL), in the Cochrane Library; Embase; Education Resource Information Center (ERIC); International Bibliography of the Social Sciences; MEDLINE; PsycINFO; and Sociological Abstracts) on three occasions (2012, 2015, and 14 November 2016)). We conducted handsearches of reference lists, contacted experts in the field, conducted citation searches, and searched websites of relevant organisations. SELECTION CRITERIA: We included randomised controlled trials (RCTs), including cluster RCTs, which aimed to address at least two risk behaviours. Participants were children and young people up to 18 years of age and/or parents, guardians, or carers, as long as the intervention aimed to address involvement in multiple risk behaviours among children and young people up to 18 years of age. However, studies could include outcome data on children > 18 years of age at the time of follow-up. Specifically,we included studies with outcomes collected from those eight to 25 years of age. Further, we included only studies with a combined intervention and follow-up period of six months or longer. We excluded interventions aimed at individuals with clinically diagnosed disorders along with clinical interventions. We categorised interventions according to whether they were conducted at the individual level; the family level; or the school level. DATA COLLECTION AND ANALYSIS: We identified a total of 34,680 titles, screened 27,691 articles and assessed 424 full-text articles for eligibility. Two or more review authors independently assessed studies for inclusion in the review, extracted data, and assessed risk of bias.We pooled data in meta-analyses using a random-effects (DerSimonian and Laird) model in RevMan 5.3. For each outcome, we included subgroups related to study type (individual, family, or school level, and universal or targeted approach) and examined effectiveness at up to 12 months' follow-up and over the longer term (> 12 months). We assessed the quality and certainty of evidence using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach. MAIN RESULTS: We included in the review a total of 70 eligible studies, of which a substantial proportion were universal school-based studies (n = 28; 40%). Most studies were conducted in the USA (n = 55; 79%). On average, studies aimed to prevent four of the primary behaviours. Behaviours that were most frequently addressed included alcohol use (n = 55), drug use (n = 53), and/or antisocial behaviour (n = 53), followed by tobacco use (n = 42). No studies aimed to prevent self-harm or gambling alongside other behaviours.Evidence suggests that for multiple risk behaviours, universal school-based interventions were beneficial in relation to tobacco use (odds ratio (OR) 0.77, 95% confidence interval (CI) 0.60 to 0.97; n = 9 studies; 15,354 participants) and alcohol use (OR 0.72, 95% CI 0.56 to 0.92; n = 8 studies; 8751 participants; both moderate-quality evidence) compared to a comparator, and that such interventions may be effective in preventing illicit drug use (OR 0.74, 95% CI 0.55 to 1.00; n = 5 studies; 11,058 participants; low-quality evidence) and engagement in any antisocial behaviour (OR 0.81, 95% CI 0.66 to 0.98; n = 13 studies; 20,756 participants; very low-quality evidence) at up to 12 months' follow-up, although there was evidence of moderate to substantial heterogeneity (I2 = 49% to 69%). Moderate-quality evidence also showed that multiple risk behaviour universal school-based interventions improved the odds of physical activity (OR 1.32, 95% CI 1.16 to 1.50; I2 = 0%; n = 4 studies; 6441 participants). We considered observed effects to be of public health importance when applied at the population level. Evidence was less certain for the effects of such multiple risk behaviour interventions for cannabis use (OR 0.79, 95% CI 0.62 to 1.01; P = 0.06; n = 5 studies; 4140 participants; I2 = 0%; moderate quality evidence), sexual risk behaviours (OR 0.83, 95% CI 0.61 to 1.12; P = 0.22; n = 6 studies; 12,633 participants; I2 = 77%; low-quality evidence), and unhealthy diet (OR 0.82, 95% CI 0.64 to 1.06; P = 0.13; n = 3 studies; 6441 participants; I2 = 49%; moderate-quality evidence). It is important to note that some evidence supported the positive effects of universal school-level interventions on three or more risk behaviours.For most outcomes of individual- and family-level targeted and universal interventions, moderate- or low-quality evidence suggests little or no effect, although caution is warranted in interpretation because few of these studies were available for comparison (n <= 4 studies for each outcome).Seven studies reported adverse effects, which involved evidence suggestive of increased involvement in a risk behaviour among participants receiving the intervention compared to participants given control interventions.We judged the quality of evidence to be moderate or low for most outcomes, primarily owing to concerns around selection, performance, and detection bias and heterogeneity between studies. AUTHORS' CONCLUSIONS: Available evidence is strongest for universal school-based interventions that target multiple- risk behaviours, demonstrating that they may be effective in preventing engagement in tobacco use, alcohol use, illicit drug use, and antisocial behaviour, and in improving physical activity among young people, but not in preventing other risk behaviours. Results of this review do not provide strong evidence of benefit for family- or individual-level interventions across the risk behaviours studied. However, poor reporting and concerns around the quality of evidence highlight the need for high-quality multiple- risk behaviour intervention studies to further strengthen the evidence base in this field. PMID- 30288739 TI - Inhaled nitric oxide. AB - Nitric oxide (NO) is a gas that induces relaxation of smooth muscle cells in the vasculature. Because NO reacts with oxyhaemoglobin with high affinity, the gas is rapidly scavenged by oxyhaemoglobin in red blood cells and the vasodilating effects of inhaled NO are limited to ventilated regions in the lung. NO therefore has the unique ability to induce pulmonary vasodilatation specifically in the portions of the lung with adequate ventilation, thereby improving oxygenation of blood and decreasing intrapulmonary right to left shunting. Inhaled NO is used to treat a spectrum of cardiopulmonary conditions, including pulmonary hypertension in children and adults. However, the widespread use of inhaled NO is limited by logistical and financial barriers. We have designed, developed and tested a simple and economic NO generation device, which uses pulsed electrical discharges in air to produce therapeutic levels of NO that can be used for inhalation therapy.

AB - Cricoid force is widely applied to decrease the risk of pulmonary aspiration and gastric antral insufflation of air during positive-pressure ventilation, yet its efficacy remains controversial. We compared manual oesophageal compression at the low left paratracheal and cricoid levels for the prevention of gastric antral air insufflation during positive-pressure ventilation by facemask in patients scheduled for elective surgery under general anaesthesia. After gaining written consent, participants were randomly allocated by sealed envelope to one of three groups: oesophageal compression by 30 N paratracheal force (paratracheal group); oesophageal compression by 30 N cricoid force (cricoid group); or no oesophageal compression (control group). Gastric insufflation of air was assessed before and after positive-pressure ventilation by ultrasound measurement of the antral cross sectional area and/or presence of air artefacts in the antrum. The primary outcome measure was the proportion of participants with ultrasound evidence of gastric insufflation. We recruited 30 patients into each group. Before facemask ventilation, no air artefacts were visible in the antrum in any of the participants. After facemask ventilation of the participant's lungs, no air artefacts were seen in the paratracheal group, compared with six subjects in the cricoid group and eight subjects in the control group (p = 0.012). Our results suggest that oesophageal compression can be achieved by the application of manual force at the low left paratracheal level and that this is more effective than cricoid force in preventing air entry into the gastric antrum during positive pressure ventilation by facemask. PMID- 30288742 TI - An analysis of a multiple biomarker panel to better predict prostate cancer metastasis after radical prostatectomy. AB - A plethora of individual candidate biomarkers for predicting biochemical relapse in localized prostate cancer (PCa) have been proposed. Combined biomarkers may improve prognostication, and ensuring validation against more clinically relevant endpoints are required. The Australian PCa Research Centre NSW has contributed to numerous studies of molecular biomarkers associated with biochemical relapse. In the current study, these biomarkers were re-analyzed for biochemical relapse, metastatic relapse and PCa death with extended follow-up. Biomarkers of significance were then used to develop a combined prognostic model for clinical outcomes and validated in a large independent cohort. The discovery cohort (n = 324) was based on 12 biomarkers with a median follow-up of 16 years. Seven biomarkers were significantly associated with biochemical relapse. Three biomarkers were associated with metastases: AZGP1, Ki67 and PML. Only AZGP1 was associated with PCa death. In their individual and combinational forms, AZGP1 and Ki67 as a dual BM signature was the most robust predictor of metastatic relapse (AUC 0.762). The AZPG1 and Ki67 signature was validated in an independent cohort of 347 PCa patients. The dual BM signature of AZGP1 and Ki67 predicted metastasis in the univariable (HR 7.2, 95% CI, 1.6-32; p = 0.01) and multivariable analysis (HR 5.4, 95% CI, 1.2-25; p = 0.03). The dual biomarker signature marginally improved risk prediction compared to AZGP1 alone (AUC 0.758 versus 0.738, p < 0.001). Our findings indicate that biochemical relapse is not an adequate surrogate for metastasis or PCa death. The dual biomarker signature of AZGP1 and Ki67 offers a small benefit in predicting metastasis over AZGP1 alone. PMID- 30288743 TI - Pathogen enrichment sequencing (PenSeq) enables population genomic studies in oomycetes. AB - The oomycete pathogens Phytophthora infestans and P. capsici cause significant crop losses world-wide, threatening food security. In each case, pathogenicity factors, called RXLR effectors, contribute to virulence. Some RXLRs are perceived by resistance proteins to trigger host immunity, but our understanding of the demographic processes and adaptive evolution of pathogen virulence remains poor. Here, we describe PenSeq, a highly efficient enrichment sequencing approach for genes encoding pathogenicity determinants which, as shown for the infamous potato blight pathogen Phytophthora infestans, make up < 1% of the entire genome. PenSeq facilitates the characterization of allelic diversity in pathogen effectors, enabling evolutionary and population genomic analyses of Phytophthora species. Furthermore, PenSeq enables the massively parallel identification of presence/absence variations and sequence polymorphisms in key pathogen genes, which is a prerequisite for the efficient deployment of host resistance genes. PenSeq represents a cost-effective alternative to whole-genome sequencing and addresses crucial limitations of current plant pathogen population studies, which are often based on selectively neutral markers and consequently have limited utility in the analysis of adaptive evolution. The approach can be adapted to diverse microbes and pathogens. PMID- 30288744 TI - Sadder but wiser: Emotional reactions and wisdom in a simulated suicide intervention. AB - Scholars within the Berlin paradigm have analysed participants' responses to a hypothetical vignette about a friend's suicide ideation. However, no study has yet focused on participants' emotional reactions to this scenario, an important aspect of wisdom performance. We conducted a Thin-Slice Wisdom study where participants were asked to give advice to a hypothetical friend contemplating suicide. We analysed their emotional profiles using facial expression analysis software (FACET2.1 and FACEREADER7.1). Participants' verbal responses were also transcribed and then scored by 10 raters using the Berlin criteria. Results revealed that the sadder the participants felt, the wiser their performance. Wiser participants may have been better at exploring this sad, but true, existential human dilemma. PMID- 30288745 TI - Comparative characterization of putative chitin deacetylases from Phaeodactylum tricornutum and Thalassiosira pseudonana highlights the potential for distinct chitin-based metabolic processes in diatoms. AB - Chitin is generally considered to be present in centric diatoms but not in pennate species. Many aspects of chitin biosynthetic pathways have not been explored in diatoms. We retrieved chitin metabolic genes from pennate (Phaeodactylum tricornutum) and centric (Thalassiosira pseudonana) diatom genomes. Chitin deacetylase (CDA) genes from each genome (PtCDA and TpCDA) were overexpressed in P. tricornutum. We performed comparative analysis of their sequence structure, phylogeny, transcriptional profiles, localization and enzymatic activities. The chitin relevant proteins show complex subcellular compartmentation. PtCDA was likely acquired by horizontal gene transfer from prokaryotes, whereas TpCDA has closer relationships with sequences in Opisthokonta. Using transgenic P. tricornutum lines expressing CDA-green fluorescent protein (GFP) fusion proteins, PtCDA predominantly localizes to Golgi apparatus whereas TpCDA localizes to endoplasmic reticulum/chloroplast endoplasmic reticulum membrane. CDA-GFP overexpression upregulated the transcription of chitin synthases and potentially enhanced the ability of chitin synthesis. Although both CDAs are active on GlcNAc5 , TpCDA is more active on the highly acetylated chitin polymer DA60. We have addressed the ambiguous characters of CDAs from P. tricornutum and T. pseudonana. Differences in localization, evolution, expression and activities provide explanations underlying the greater potential of centric diatoms for chitin biosynthesis. This study paves the way for in vitro applications of novel CDAs. PMID- 30288746 TI - Evolution and expression of core SWI/SNF genes in red algae. AB - Red algae are the oldest identifiable multicellular eukaryotes, with a fossil record dating back more than a billion years. During that time two major rhodophyte lineages, bangiophytes and florideophytes, have evolved varied levels of morphological complexity. These two groups are distinguished, in part, by different patterns of multicellular development, with florideophytes exhibiting a far greater diversity of morphologies. Interestingly, during their long evolutionary history, there is no record of a rhodophyte achieving the kinds of cellular and tissue-specific differentiation present in other multicellular algal lineages. To date, the genetic underpinnings of unique aspects of red algal development are largely unexplored; however, they must reflect the complements and patterns of expression of key regulatory genes. Here we report comparative evolutionary and gene expression analyses of core subunits of the SWI/SNF chromatin-remodeling complex, which is implicated in cell differentiation and developmental regulation in more well studied multicellular groups. Our results suggest that a single, canonical SWI/SNF complex was present in the rhodophyte ancestor, with gene duplications and evolutionary diversification of SWI/SNF subunits accompanying the evolution of multicellularity in the common ancestor of bangiophytes and florideophytes. Differences in how SWI/SNF chromatin remodeling evolved subsequently, in particular gene losses and more rapid divergence of SWI3 and SNF5 in bangiophytes, could help to explain why they exhibit a more limited range of morphological complexity than their florideophyte cousins. PMID- 30288747 TI - Transcriptomic analysis reveals the possible roles of sugar metabolism and export for positive mycorrhizal growth responses in soybean. AB - To elucidate molecular mechanisms controlling differential growth responses to root colonization by arbuscular mycorrhizal (AM) fungi varying in colonization and cooperative behavior, a pot experiment was carried out using two soybean genotypes and three AM inocula. The results showed that inoculation by cooperative Rhizophagus irregularis (Ri) or less cooperative Glomus aggregatum with high AM colonization (Ga-H) significantly promoted plant growth compared with inoculation by G. aggregatum with low AM colonization (Ga-L). A comparative RNA sequencing analysis of the root transcriptomes showed that fatty acid synthesis pathway was significantly enriched in all three AM inoculation roots. However, sugar metabolism and transport were significantly enriched only in Ri and Ga-H inoculation, which was consistent with positive growth responses in these two inoculation treatments. Accordingly, the expression levels of the key genes related to sugar metabolism and transport were also upregulated in Ri and Ga-H roots compared with Ga-L roots. Of them, two sugars will eventually be exported transporters (SWEET) transporter genes, GmSWEET6 (Glyma.04G198600) and GmSWEET15 (Glyma.06G166800), and one invertase (Glyma.17G227900) gene were exclusively induced only in Ri and Ga-H roots. Promoter analyses in transgenic soybean roots further demonstrated that GUS driven by the GmSWEET6 promoter was highly expressed in arbuscule-containing cortical cells. Additionally, Ri and Ga H inoculation increased the contents of sucrose, glucose and fructose in both shoots and roots compared with those of Ga-L and non-mycorrhizal. These results imply that positive mycorrhizal growth responses in plants might mostly be due to the stimulation of photosynthate metabolism and transport by AM fungal inoculum with high colonization capabilities. PMID- 30288748 TI - Avoiding damage to transvenous leads-A comparison of electrocautery techniques and two insulated electrocautery blades. AB - BACKGROUND: Electrocautery (cautery) can damage transvenous cardiac device leads. The purpose of this study was to compare lead damage from an insulated cautery blade when used with several different techniques that included coagulation (COAG) versus cutting (CUT) mode, perpendicular active edge (active) versus parallel flat blade (flat) orientation (phase 1), and using one commercially available blade (PhotonBlade) versus another (PlasmaBlade) (phase 2). METHODS: In phase 1, lesions were delivered using combinations of: (1) COAG and CUT; (2) active and flat orientation; and (3) polyurethane, silicone, and copolymer insulation. In phase 2, lesions were delivered using combinations of: (1) PlasmaBlade and PhotonBlade, (2) four power output levels, and (3) eight different lead models. Lead damage was scored on an ordinal scale of 0 to 4. RESULTS: Phase 1: more leads were damaged using COAG than CUT (48% vs 2%, P < 0.0001). When using COAG, 74% of lesions using active orientation had damage versus 22% of lesions using flat orientation (P = 0.0002). COAG lesions to copolymer (61%) and polyurethane (68%) leads had greater damage than silicone (17%) (P = 0.006 and P = 0.003, respectively). Phase 2: 75% of treatments using PlasmaBlade had damage versus 40% of treatments with PhotonBlade (P < 0.0001). Higher power resulted in more damage. At the commonly used setting of CUT 20 W, damage occurred in 39% of treatments using PlasmaBlade versus 13% using PhotonBlade (P = 0.0006). CONCLUSIONS: COAG resulted in more damage than CUT; this effect was greatest with the active edge, and with polyurethane or copolymer insulation. PhotonBlade was associated with less damage to leads than PlasmaBlade. PMID- 30288749 TI - Aging, the menopausal transition, and hormone replenishment therapy: retrieval of confidence and compliance. AB - The negative health consequences of age and the postmenopausal hypoestrogenic state and their clinical management are described in this paper. While some dysfunctional elements are irreversibly entrained, others can be modified by an updated menopausal hormone therapy (MHT) strategy reflecting revision and reassessment of the initial Women's Health Initiative (WHI) reports. However, until that positive outcome is realized, menopausal women and their healthcare providers must re-establish willingness to utilize these effective strategies. This reluctance is fueled by persistent mistaken application of WHI results that reflect the bundled risk and benefits of MHT in asymptomatic women aged 50-79 (average age 63), as opposed to women in their 40s and 50s who initiate therapy because of vasomotor symptoms. The absolute risk of adverse outcomes is much lower and the benefits dramatically higher in these younger women. In addition, newer FDA-approved formulations, lower dosage regimens, and transdermal delivery methodologies offer wider choice of approaches and promise even greater safety. The positive and negative lessons of the WHI have been learned and can be applied effectively. PMID- 30288750 TI - Albugo candida race diversity, ploidy and host-associated microbes revealed using DNA sequence capture on diseased plants in the field. AB - Physiological races of the oomycete Albugo candida are biotrophic pathogens of diverse plant species, primarily the Brassicaceae, and cause infections that suppress host immunity to other pathogens. However, A. candida race diversity and the consequences of host immunosuppression are poorly understood in the field. We report a method that enables sequencing of DNA of plant pathogens and plant associated microbes directly from field samples (Pathogen Enrichment Sequencing: PenSeq). We apply this method to explore race diversity in A. candida and to detect A. candida-associated microbes in the field (91 A. candida-infected plants). We show with unprecedented resolution that each host plant species supports colonization by one of 17 distinct phylogenetic lineages, each with an unique repertoire of effector candidate alleles. These data reveal the crucial role of sexual and asexual reproduction, polyploidy and host domestication in A. candida specialization on distinct plant species. Our bait design also enabled phylogenetic assignment of DNA sequences from bacteria and fungi from plants in the field. This paper shows that targeted sequencing has a great potential for the study of pathogen populations while they are colonizing their hosts. This method could be applied to other microbes, especially to those that cannot be cultured. PMID- 30288752 TI - Micra implantation in a patient with transposition of great arteries. AB - We describe a 56-year-old male with transposition of the great arteries and Mustard repair, superior vena cava obstruction, atrial fibrillation, and progressive deterioration of his epicardial lead performance. We were successful in deploying of Micra (Medtronic, Minneapolis, MN, USA) at the septo-apical area of his nonsystemic ventricle in a stable position with satisfactory pacing and sensing thresholds. PMID- 30288751 TI - FoxO1 is a critical regulator of M2-like macrophage activation in allergic asthma. AB - BACKGROUND: The pathogenesis of asthma and airway obstruction is the result of an abnormal response to different environmental exposures. The scientific premise of our study was based on the finding that FoxO1 expression is increased in lung macrophages of mice after allergen exposure and human asthmatic patients. Macrophages are capable of switching from one functional phenotype to another, and it is important to understand the mechanisms involved in the transformation of macrophages and how their cellular function affects the peribronchial stromal microenvironment. METHODS: We employed a murine asthma model, in which mice were treated by intranasal insufflation with allergens for 2-8 weeks. We used both a pharmacologic approach using a highly specific FoxO1 inhibitor and genetic approaches using FoxO1 knockout mice (FoxO1fl/fl LysMcre). Cytokine level in biological fluids was measured by ELISA and the expression of encoding molecules by NanoString assay and qRT-PCR. RESULTS: We show that the levels of FoxO1 gene are significantly elevated in the airway macrophages of patients with mild asthma in response to subsegmental bronchial allergen challenge. Transcription factor FoxO1 regulates a pro-asthmatic phenotype of lung macrophages that is involved in the development and progression of chronic allergic airway disease. We have shown that inhibition of FoxO1 induced phenotypic conversion of lung macrophages and downregulates pro-asthmatic and pro-fibrotic gene expression by macrophages, which contribute to airway inflammation and airway remodeling in allergic asthma. CONCLUSION: Targeting FoxO1 with its downstream regulator IRF4 is a novel therapeutic target for controlling allergic inflammation and potentially reversing fibrotic airway remodeling. PMID- 30288753 TI - Biatrial volume, estimated using magnetic resonance imaging, predicts atrial fibrillation recurrence after ablation. AB - INTRODUCTION: The predictive value of left atrial volume (LAV) in atrial fibrillation (AF) is known, but the relationship of right atrial volume (RAV) and biatrial volume (BAV) with AF recurrence after pulmonary vein isolation (PVI) is not clear. Cardiac magnetic resonance (CMR) imaging allows us to more precisely quantify atrial volume. We investigated LAV, RAV, and BAV as predictors of AF recurrence following PVI in AF patients. METHODS AND RESULTS: We assessed 100 AF patients (age = 59.8 +/- 9.5 years, 74 males, 26 females) who underwent nonenhanced CMR before their first PVI. LAV and RAV were measured using CMR. All patients were in sinus rhythm during CMR. BAV was calculated as the sum of LAV and RAV. During the 8-month follow-up, AF recurrence occurred in 23 patients. LAV, RAV, and BAV were significantly greater in patients with AF recurrence than in those without (LAV, 103.7 +/- 25.8 vs 81.8 +/- 24.2 mL, P < 0.001; RAV, 109.4 +/- 27.0 vs 82.2 +/- 19.6 mL, P < 0.001; BAV, 213.1 +/- 46.7 vs 164.1 +/- 38.7 mL, P < 0.001). Multivariate logistic regression analysis revealed that increased LAV, RAV, and BAV were significantly correlated with AF recurrence. The area under the receiver operation characteristic curve for BAV showed the largest value compared to that of LAV or RAV alone. CONCLUSIONS: LAV, RAV, and BAV were independent predictors of AF recurrence after PVI. Quantifying BAV may additionally improve prognostic stratification compared with LAV or RAV. PMID- 30288754 TI - The regulatory module MdPUB29-MdbHLH3 connects ethylene biosynthesis with fruit quality in apple. AB - The plant hormone ethylene is critical for climacteric fruit ripening, while glucose and anthocyanins determine the fruit quality of climacteric fruits such as apple. Understanding the exact molecular mechanism for this process is important for elucidating the interconnection of ethylene and fruit quality. Overexpression of apple MdbHLH3 gene, an anthocyanin-related basic helix-loop helix transcription factor (bHLH TF) gene, promotes ethylene production, and transgenic apple plantlets and trees exhibit ethylene-related root developmental abnormalities, premature leaf senescence, and fruit ripening. Biochemical analyses demonstrate that MdbHLH3 binds to the promoters of three genes that are involved in ethylene biosynthesis, including MdACO1, MdACS1, and MdACS5A, activating their transcriptional expression, thereby promoting ethylene biosynthesis. High glucose-inhibited U-box-type E3 ubiquitin ligase MdPUB29, the ortholog of Arabidopsis AtPUB29 in apple, influences the expression of ethylene biosynthetic genes and ethylene production by direct ubiquitination of the MdbHLH3 protein. Our findings provide new insights into the ubiquitination of MdbHLH3 by glucose-inhibited ubiquitin E3 ligase MdPUB29 in the regulation of ethylene biosynthesis as well as indicate that the regulatory module MdPUB29 MdbHLH3 connects ethylene biosynthesis with fruit quality in apple. PMID- 30288755 TI - Breakthrough percepts of famous faces. AB - Recently, we showed that presenting salient names (i.e., a participant's first name) on the fringe of awareness (in rapid serial visual presentation, RSVP) breaks through into awareness, resulting in the generation of a P3, which (if concealed information is presented) could be used to differentiate between deceivers and nondeceivers. The aim of the present study was to explore whether face stimuli can be used in an ERP-based RSVP paradigm to infer recognition of broadly familiar faces. To do this, we explored whether famous faces differentially break into awareness when presented in RSVP and, importantly, whether ERPs can be used to detect these breakthrough events on an individual basis. Our findings provide evidence that famous faces are differentially perceived and processed by participants' brains as compared to novel (or unfamiliar) faces. EEG data revealed large differences in brain responses between these conditions. PMID- 30288756 TI - Sonographic diagnosis of coexisting ectopic thyroid and fourth branchial cleft cyst. AB - Ectopic thyroid and fourth branchial cleft anomaly are rare congenital anomalies of the neck. This is a case report of the coexistence of these two rare congenital anomalies in a 1-year-old girl. She had ectopic lingual thyroid and asymptomatic abscess in the fourth branchial cleft cyst, which was found in ultrasonography carried out to evaluate congenital hypothyroidism. To the best of our knowledge, this is the first reported case of ectopic thyroid coexisting with fourth branchial cleft anomaly in the same patient.

AB - Potassium (K) and magnesium (Mg) are essential macronutrients for plants; they play crucial roles for photoassimilate production and transport. The knowledge on both individual and interactive effects of K and Mg nutrition in potato (Solanum tuberosum L.) is limited. We aimed to determine whether K or Mg deficiencies impair photoassimilate production and transport, and consequently the development of tubers which are strong sink organs for photoassimilates. Potato plants were grown in pots using sand culture under various K and Mg supplies. Biomass production, CO2 net assimilation, leaf sugar concentrations and transcript levels of H+ /sucrose symporters in leaves were measured. Both K and Mg deficiencies reduced CO2 net assimilation and biomass production, with stronger reductions during K deficiency. Sugars accumulated in K- and, more importantly, in Mg deficient leaves. Low K or Mg supplies resulted in increased transcript levels of H+ /sucrose symporters, but the increase was less pronounced during Mg deficiency. The lower increase of transcript levels of H+ /sucrose symporters under Mg deficiency was probably caused by an impaired sucrose transport already at an earlier step, namely the efflux of sucrose from mesophyll cells into the apoplast. Thus, we assume that K and Mg deficiencies caused sugar accumulation in separated cell compartments of source leaves leading to a different impact on the gene expression of sucrose transport systems. Tuber sugar and starch concentrations, however, remained unaffected under the various treatments. Nevertheless, the total amount of tuber sugar and starch per plant decreased significantly during K and Mg deficiencies. This article is protected by copyright. All rights reserved.

AB - PURPOSE: To design and implement a novel treatment planning algorithm based on a modification of dynamic conformal arc (DCA) therapy for the treatment of multiple cranial metastases with variable prescription doses. METHODS: A workflow was developed in which separate dose matrices were calculated for each target at each control point (i.e., the multileaf collimator (MLC) was fit conformally to that single target). A cost function was used to quantify the relative contributions of each dose matrix in the plan to the overall plan objectives. Simulated annealing was used to allow for the inclusion or exclusion of individual dose matrices at each control point. The exclusion of individual targets at a given control point is termed intra-arc binary collimation (iABC) in this work and is accomplished by closing the MLCs over the target for a duration specified by simulated annealing optimization. Dynamic collimator motions were employed to minimize the variation between the idealized dose matrices (i.e., perfectly collimated targets) and actual dose matrices (i.e., MLC apertures that include quantities of nontarget tissue due to the relative orientations of targets in the field). An additional simulated annealing optimization was performed to weight the relative contributions of dose at each control point [referred to as the monitor unit distribution (MUD)] to improve compliance with plan objectives. The algorithm was tested on seven previously treated multiple metastases patients and plans were compared to the clinically treated VMAT plans. RESULTS: Treatment plans generated with iABC used an average of 2716 (34%) fewer MU in the total plan than VMAT (P = 0.01). All normal tissue metrics for all plans and all patients were clinically acceptable. There were no statistically significant differences in any normal tissue dose metrics. Normalized prescription target coverage accuracy for all targets was 3% better on average for VMAT plans when compared to iABC (P = 0.07), and 14% better on average for iABC when compared to optimized DCA (P = 0.03). CONCLUSION: A novel method of aperture and dose distribution design has been developed to significantly increase the MU efficiency of single isocenter treatment of multiple metastases with variable prescription doses when compared to VMAT, and which improves target coverage accuracy significantly when compared to optimized DCA. By applying a DCA approach to subsets of targets across control points, a hybrid method of treatment delivery has been developed that combines the efficiency of dynamic conformal treatments and the dosimetric flexibility of VMAT. PMID- 30288759 TI - Hypoalbuminemia: Pathogenesis and Clinical Significance. AB - Hypoalbuminemia is associated with inflammation. Despite being addressed repeatedly in the literature, there is still confusion regarding its pathogenesis and clinical significance. Inflammation increases capillary permeability and escape of serum albumin, leading to expansion of interstitial space and increasing the distribution volume of albumin. The half-life of albumin has been shown to shorten, decreasing total albumin mass. These 2 factors lead to hypoalbuminemia despite increased fractional synthesis rates in plasma. Hypoalbuminemia, therefore, results from and reflects the inflammatory state, which interferes with adequate responses to events like surgery or chemotherapy, and is associated with poor quality of life and reduced longevity. Increasing or decreasing serum albumin levels are adequate indicators, respectively, of improvement or deterioration of the clinical state. In the interstitium, albumin acts as the main extracellular scavenger, antioxidative agent, and as supplier of amino acids for cell and matrix synthesis. Albumin infusion has not been shown to diminish fluid requirements, infection rates, and mortality in the intensive care unit, which may imply that there is no body deficit or that the quality of albumin "from the shelf" is unsuitable to play scavenging and antioxidative roles. Management of hypoalbuminaemia should be based on correcting the causes of ongoing inflammation rather than infusion of albumin. After the age of 30 years, muscle mass and function slowly decrease, but this loss is accelerated by comorbidity and associated with decreasing serum albumin levels. Nutrition support cannot fully prevent, but slows down, this chain of events, especially when combined with physical exercise. PMID- 30288761 TI - Zero-Balance Ultrafiltration of Priming Blood Attenuates Procalcitonin and Improves the Respiratory Function in Infants After Cardiopulmonary Bypass: A Randomized Controlled Trial. AB - Blood priming is needed for cardiopulmonary bypass (CPB) in neonates and infants to avoid exceeding hemodilution; however, transfusion-related inflammation affects post-CPB outcomes in infant open-heart surgery. Procalcitonin, a newly detected inflammatory moderator and a sensitive parameter for predicting pulmonary dysfunction secondary to CPB, rises after CPB. We hypothesized that the hemofiltration of priming blood before CPB might decrease inflammatory mediators in the blood and post-CPB inflammatory replications, thereby improving the respiratory function after CPB in infants. Sixty infants with a weight below 10 kg were divided randomly into two equal groups of CPB with the zero-balance ultrafiltration (Z-BUF) of priming blood and CPB without it. The procalcitonin level was measured before anesthesia, after admission to the intensive care unit (ICU), and 24 h afterward. The respiratory index and pulmonary compliance were measured after anesthesia, at the end of CPB, and 2 h after admission to the ICU. Additionally, time to extubation was recorded. The Z-BUF of priming blood maintained electrolytes within a physiologic level, and procalcitonin had a slighter rise in the Z-BUF Group at 24 h after admission to the ICU (P = 0.05). The respiratory index was decreased in the Z-BUF Group, but the difference with the control group did not reach statistical significance (P > 0.05). The change in pulmonary compliance was significantly increased in the cyanotic patients in the intervention group, but there was no significant difference between the two groups. The time to extubation and the ICU stay were shorter in the Z-BUF Group (P < 0.05). A positive correlation was found between the peak procalcitonin concentration and the time to extubation directly and pulmonary compliance reversely. These results suggest that the Z-BUF of priming blood may have some beneficial clinical effects such as improved respiratory function and attenuated procalcitonin. PMID- 30288760 TI - ZmMADS69 functions as a flowering activator through the ZmRap2.7-ZCN8 regulatory module and contributes to maize flowering time adaptation. AB - Flowering time is a major determinant of the local adaptation of plants. Although numerous loci affecting flowering time have been mapped in maize, their underlying molecular mechanisms and roles in adaptation remain largely unknown. Here, we report the identification and characterization of MADS-box transcription factor ZmMADS69 that functions as a flowering activator through the ZmRap2.7-ZCN8 regulatory module and contributes to adaptation. We show that ZmMADS69 underlies a quantitative trait locus controlling the difference in flowering time between maize and its wild ancestor, teosinte. Maize ZmMADS69 allele is expressed at a higher level at floral transition and confers earlier flowering than the teosinte allele under long days and short days. Overexpression of ZmMADS69 causes early flowering, while a transposon insertion mutant of ZmMADS69 exhibits delayed flowering. ZmMADS69 shows pleiotropic effects for multiple traits of agronomic importance. ZmMADS69 functions upstream of the flowering repressor ZmRap2.7 to downregulate its expression, thereby relieving the repression of the florigen gene ZCN8 and causing early flowering. Population genetic analyses showed that ZmMADS69 was a target of selection and may have played an important role as maize spread from the tropics to temperate zones. Our findings provide important insights into the regulation and adaptation of flowering time. PMID- 30288762 TI - Recovery of missing data in partial geometry PET scanners: Compensation in projection space vs image space. AB - PURPOSE: Robust and reliable reconstruction of images from noisy and incomplete projection data holds significant potential for proliferation of cost-effective medical imaging technologies. Since conventional reconstruction techniques can generate severe artifacts in the recovered images, a notable line of research constitutes development of appropriate algorithms to compensate for missing data and to reduce noise. In the present work, we investigate the effectiveness of state-of-the-art methodologies developed for image inpainting and noise reduction to preserve the quality of reconstructed images from undersampled PET data. We aimed to assess and ascertain whether missing data recovery is best performed in the projection space prior to reconstruction or adjoined with the reconstruction step in image space. METHODS: Different strategies for data recovery were investigated using realistic patient derived phantoms (brain and abdomen) in PET scanners with partial geometry (small and large gap structures). Specifically, gap filling strategies in projection space were compared with reconstruction based compensation in image space. The methods used for filling the gap structure in sinogram PET data include partial differential equation based techniques (PDE), total variation (TV) regularization, discrete cosine transform(DCT)-based penalized regression, and dictionary learning based inpainting (DLI). For compensation in image space, compressed sensing based image reconstruction methods were applied. These include the preconditioned alternating projection (PAPA) algorithm with first and higher order total variation (HOTV) regularization as well as dictionary learning based compressed sensing (DLCS). We additionally investigated the performance of the methods for recovery of missing data in the presence of simulated lesion. The impact of different noise levels in the undersampled sinograms on performance of the approaches were also evaluated. RESULTS: In our first study (brain imaging), DLI was shown to outperform other methods for small gap structure in terms of root mean square error (RMSE) and structural similarity (SSIM), though having relatively high computational cost. For large gap structure, HOTV-PAPA produces better results. In the second study (abdomen imaging), again the best performance belonged to DLI for small gap, and HOTV-PAPA for large gap. In our experiments for lesion simulation on patient brain phantom data, the best performance in term of contrast recovery coefficient (CRC) for small gap simulation belonged to DLI, while in the case of large gap simulation, HOTV-PAPA outperformed others. Our evaluation of the impact of noise on performance of approaches indicated that in case of low and medium noise levels, DLI still produces favorable results among inpainting approaches. However, for high noise levels, the performance of PDE4 (variant of PDE) and DLI are very competitive. CONCLUSIONS: Our results showed that estimation of missing data in projection space as a preprocessing step before reconstruction can improve the quality of recovered images especially for small gap structures. However, when large portions of data are missing, compressed sensing techniques adjoined with the reconstruction step in image space were the best strategy.

PMID- 30288765 TI - Power calculation of adjusted McNemar's test based on clustered data of varying cluster size. AB - McNemars test is often used to compare two proportions estimated from paired observations. When the observations are sampled in clusters, adjustment is needed to ensure that the size of McNemars test does not exceed the nominal level. Eliasziw and Donner (1991) developed an adjustment to McNemars test that involves first estimating the correlation between discordant pairs within a cluster, then using the estimate of the correlation to adjust the usual McNemar's test statistic. Gonen (2004) derived two approximations for calculating the power and sample size for the adjusted McNemar's test. He reported that the accuracy of the two approximations is compromised for large value of intracluster correlation and small value of proportion of discordant pairs; the error of the approximation can be higher than 10 per cent. In this paper, we extend his power formula, developed under fixed cluster size assumption, to accommodate the case where the cluster sizes are not constant. We show via simulations that the theoretical powers calculated from our proposed power formula are close to their empirical counterparts under a variety of settings. More significantly, in the case of fixed cluster size, our reduced power formula provides a more accurate power approximation than Gonen's power formula regardless of the values of intracluster correlation and the proportion of discordant pairs. PMID- 30288766 TI - The case against categorical risk estimates. AB - Risk estimates can be communicated in a variety of forms, including numeric and categorical formats. An example of the latter is "low/medium/high risk." The categorical format is preferred by judges and practitioners alike, and is mandated by the most commonly utilized forensic risk assessment instruments (the HCR-20 and the Static-99). This article argues against the practice of communicating risk in categorical terms on empirical and normative grounds. Empirically, there is no consensus about what level of risk corresponds to a particular category, such as "high risk." Moreover, recent studies indicate that categorizing an otherwise continuous risk estimate does not add incremental predictive validity to the risk estimate. Normatively, categorization obscures what is fundamentally a value judgment about the relative costs and benefits of correct (e.g., true positive) and incorrect (e.g., false positive) outcomes. Such a judgment is inherently non-scientific and invades the province of the jury. Indeed, categorical risk estimates are in principle no different than "dangerousness predictions," which are simply binary and which have been denounced by the field. The fact that alternative risk communication formats have limitations does not justify continuing the pervasive practice of communicating categorical risk estimates. PMID- 30288767 TI - Predictors of advanced fibrosis in non-cirrhotic non-alcoholic fatty liver disease in Germany. AB - BACKGROUND: Advanced fibrosis has been established as the most important predictor of overall mortality in patients with non-alcoholic fatty liver disease (NAFLD). In contrast to cirrhosis, advanced, non-cirrhotic NAFLD is difficult to identify and data from Germany are lacking. AIM: To identify clinical factors associated with advanced, non-cirrhotic fibrosis. METHODS: Patients were recruited in the prospectively enrolling European NAFLD Registry. Clinical characteristics and the performance of non-invasive surrogate scores compared with vibration-controlled transient elastography are reported. RESULTS: Two hundred and sixty-one patients with non-cirrhotic NAFLD on liver biopsy (mean age 51 years, equal sex distribution) were included. The prevalence of stage 3 fibrosis on liver biopsy was 15.7%. These patients were significantly older (57 vs 50 years, P < 0.01), had a higher body mass index (32.3 vs 30.5, P < 0.05), and more frequent arterial hypertension (78% vs 50%, P = 0.001) and type 2 diabetes (61% vs 24.1%, P < 0.001). On multivariate logistic regression, diabetes (OR = 4.68, 95% CI 2.17-10.10) and hypertension (OR = 2.91, 95% CI 1.12-7.18) were independent predictors of advanced fibrosis. Comedication included metformin in 50% and insulin in 33% of patients with diabetes. Despite the presence of cardiovascular risk factors, the use of statins was low. Liver stiffness measurement identified advanced fibrosis with an AUROC of 0.81 (95% CI 0.72 0.91). The performance of NAFLD fibrosis score, Fibrosis-4, and AST to platelet ratio index were lower with AUCs of 0.74, 0.71, and 0.67, respectively. CONCLUSIONS: The prevalence of metabolic comorbidities in a German population with non-cirrhotic biopsy-proven NAFLD is high. While the examined scores exhibit an acceptable specificity, liver stiffness measurement appeared to be superior to blood-based non-invasive surrogate scores in ruling out advanced fibrosis.

AB - In this study, the myco-reduction potential of fungi isolated from soil was ascertained by Norkrans shake flask experiment contaminated with chromium(VI). Fungal tolerance assay and induced tolerance training of the fungi were also carried out. Aspergillus niger, Penicillium, and Saccharomyces strains were isolated from the soil samples using culture based technique. Norkrans samples were collected and analyzed for Cr(VI) concentration using diphenylcarbazide spectrophotometric method. Penicillium strain was observed to be most effect at Cr(VI) concentrations of 16.1 and 8.1 mg L-1 since it was able to reduce Cr(VI) more than Saccharomyces strain and A. niger on day 20. Bio-sorption kinetics for this study was better described by pseudo second order model while Langmuir isotherm model fitted better to the equilibrium data. There was virtually steady increase in fungal growth for all the treatments through-out the experimental period. Significant negative correlation (p < 0.05) was observed between fungal growth and Cr(VI) reduction rate. The results from the induced tolerance training showed that Penicillium had the highest tolerance index (TI) values at 18, 20, and 25 mg L-1 concentrations of Cr(VI) compared to A. niger and Saccharomyces strain. These results demonstrated that these fungi have the potential to bio absorb Cr(VI) and if properly harnessed, could be used in place of conventional remediation technology to clean-up the Cr(VI) contaminant in the field. PMID- 30288771 TI - Review article: novel antivirals for hepatitis C sofosbuvir/velpatasvir/voxilaprevir, glecaprevir/pibrentasvir. AB - BACKGROUND: In 2017, the hepatitis C treatment regimens sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) and glecaprevir/pibrentasvir (G/P) received approval from the U.S. Food and Drug Administration. Although both SOF/VEL/VOX (NS5B polymerase inhibitor/NS5A inhibitor/NS3/4A protease inhibitor) and G/P (NS3/4A protease inhibitor/NS5A inhibitor) are pangenotypic regimens, they are indicated for distinct subsets of patients with hepatitis C. AIM: To compare and contrast available safety and efficacy data for SOF/VEL/VOX and G/P and outline their clinical utility. METHODS: For each of the regimens, this review outlines the indications, safety information, and the major clinical studies in which SOF/VEL/VOX and G/P were evaluated. RESULTS: SOF/VEL/VOX is positioned as a salvage regimen for patients previously treated with NS5A inhibitors and for genotype 1a- and 3-infected patients who had failed other sofosbuvir-containing regimens. G/P is the first pangenotypic regimen with an 8 week duration for treatment-naive, non-cirrhotic patients, and it is indicated for patients with any genotype who have advanced kidney disease, including those on dialysis. CONCLUSION: The addition of SOF/VEL/VOX and G/P to existing hepatitis C treatment options will expand the number of patients who are eligible for and responsive to treatment, thus increasing the possibility of eliminating hepatitis C as a public health issue. PMID- 30288770 TI - Upgrading of by-product from beverage industry through solid-state fermentation with Candida utilis and Bacillus subtilis. AB - Yellow wine lees (YWL) are the main co-products in yellow wine industry with unbalanced amino acid (AA) profiles. Solid-state fermentation was employed in this study to upgrade the YWL for ruminant animals. A 3 * 3 orthogonal design was conducted to optimize the fermentation condition for optimal crude protein (CP) yield as follows: ratio of water to total solid medium at 50 : 100 (v/w), temperature of 30 degrees C, and ratio of Candida utilis to Bacillus subtilis at 2 : 1. The contents of CP, peptides and AA of fermented products were 14.5, 40.9 and 26.1% higher than those of the unfermented respectively. In particular, the essential AA were highly improved, especially for lysine and methionine. The fermentation increased the in vitro microbial protein synthesis with higher CP digestibility and dramatically enhanced the ability of scavenging free radicals of the YWL. It is concluded that the microbial pretreatment can greatly improve the nutritional value of YWL, making these materials more suitable as feeds for animals, including ruminants. SIGNIFICANCE AND IMPACT OF THE STUDY: Yellow wine lees (YWL) are the main co-products in yellow wine industry with unbalanced amino acid (AA) profiles and are not well utilized. A strain combination of Candida utilis and Bacillus subtilis was employed to upgrade YWL. Contents of crude protein and peptides of YWL were greatly increased by microbial fermentation. Essential AAs of YWL were highly improved after the solid-state fermentation and no negative impact was observed in in vitro digestibility. Fermented YWL may be a good feed source for ruminants. PMID- 30288772 TI - Novel and recurrent mutations in keratin 1 cause epidermolytic ichthyosis and palmoplantar keratoderma. AB - Mutations in keratin genes underlie a variety of epidermal and nonepidermal cell fragility disorders, and are the genetic basis of many inherited palmoplantar keratodermas (PPKs). Epidermolytic PPK (EPPK) is an autosomal dominant disorder that can be due to mutations in the keratin 1 gene, KRT1. Epidermolytic ichthyosis (EI), the major keratinopathic ichthyosis, is characterized by congenital erythroderma, blistering and erosions of the skin. Causative mutations in KRT1 and KRT10 have been described, with PPK being present primarily in association with the former. We report four unrelated cases (one with sporadic EI and three with autosomal dominant PPK), due to two novel and two recurrent KRT1 mutations. Mutations in KRT1 are not only scattered throughout the keratin 1 protein, as opposed to being clustered, but can result in a range of phenotypes as further confirmed by these mutations, giving a complex genotype/phenotype pattern.

However, their association with mucosal healing is unknown. AIM: To examine the relationship between anxiety, depression and mucosal healing in coeliac disease. METHODS: Between 1969 and 2008, we collected data on all small intestinal biopsies with villous atrophy from Sweden's 28 pathology departments. We restricted our cohort to individuals with data on follow-up biopsy (either persistent villous atrophy [n = 3317] or mucosal healing [n = 4331]). Through Cox regression, we estimated hazard ratios (HRs) for anxiety or depression. RESULTS: During follow-up, 123 (2.8/1000 person-years) individuals with mucosal healing had developed anxiety, compared to 94 (2.1/1000 person-years) with persistent villous atrophy. Mucosal healing was hence associated with a higher risk of future anxiety (HR = 1.49; 95% CI = 1.12-1.96). Similarly, 167 (3.8/1000 person years) individuals with mucosal healing developed depression, compared to 148 (3.3/1000 person-years) with persistent villous atrophy, corresponding to a HR of 1.25 (95% CI = 0.99-1.59). Mucosal healing was more common in individuals with prior diagnoses of anxiety or depression before follow-up biopsy. Anxiety diagnosed between diagnostic and follow-up biopsy for coeliac disease was associated with an almost nine-fold increased chance of mucosal healing (odds ratio = 8.94; 95%CI = 2.03-39.27). CONCLUSION: Anxiety and depression are more common in coeliac disease patients with mucosal healing, both before and after follow-up biopsy, an association potentially mediated through more vigilant compliance with a gluten-free diet. This finding raises concern that achieving the goal of mucosal healing may come at a cost of an increased risk of mood disorders. PMID- 30288775 TI - Effects of consecutive monoculture of sweet potato on soil bacterial community as determined by pyrosequencing. AB - Soil bacteria play key roles in determining soil health and plant growth. In this study, four sweet potato fields that had been consecutively monocultured for 1, 2, 3, and 4 years were used to investigate the effect of monoculture on soil physicochemical properties and soil bacterial communities. The results revealed that continuous cropping led to a significant decline in soil pH, soil organic carbon, and soil bacterial abundance. Miseq pyrosequencing analysis of 16S rRNA genes revealed that Proteobacteria and Bacteroidetes were the main phyla in the sweet potato monoculture soils, comprising up to 66.24% of the total sequences. The relative abundances of beneficial bacteria, including Actinobacteria, Gemmatimonadetes, Firmicutes, Xanthomonadaceae, Rhodospirillaceae, and Syntrophobacteraceae, as well as their subgroups at the genus and operational taxonomic unit (OTU) levels, decreased considerably as the number of continuous cropping years increased. In contrast, the number of potentially pathogenic bacteria, such as Acidobacteria, Sphingomonadaceae, and Pedobacter accumulated with increasing years. The results also showed the alterations to the bacterial community in the sweet potato monoculture soils were mainly driven by soil pH and soil organic matter. Overall, the decline in soil quality after successive sweet potato monoculture can be attributed to the imbalance in soil properties and soil microbes, including the decrease in soil pH and soil organic carbon, and the enrichment of pathogenic bacteria at the expense of plant-beneficial bacteria. PMID- 30288776 TI - Handgrip Strength, but Not 5-Meter Walk, Adds Value to a Clinical Nutrition Assessment. AB - BACKGROUND: Decreased physical functioning is associated with malnutrition and common in acute care patients; determining loss of function is often considered part of a comprehensive nutrition assessment. Handgrip strength (HGS) and 5-meter timed walk (5m) are functional measures used in a variety of settings. This analysis sought to determine which functional measure could be added to a hospital nutrition assessment, based on its feasibility and capacity to discriminate patient subgroups. METHODS: Eligible medical patients (no delirium/dementia, admitted from community; n = 1250), recruited from 5 hospitals that participated in a previous multisite action research study, provided data on demographics, HGS, 5m, nutrition status, perceived disability, and other characteristics. RESULTS: Significantly more patients (z = 17.39, P < .00001) were able to complete HGS than 5m (92% versus 43%, respectively). Median HGS was 28.0 kg for men and 14.7 kg for women. Of patients who completed the 5m, mean completion time was 8.98 seconds (median, 6.79 seconds, SD = 6.59). 5m and HGS scores were significantly worse with patient-perceived disability (z = -9.56, t = 10.69, respectively; P < .0001; 95% confidence interval [CI], [7.33, 10.63]; [1.76, 3.18]). HGS was associated with nutrition status (t = 4.13, P < .001; 95% CI [2.02, 5.67]), although it showed poor validity as a single nutrition indicator. CONCLUSIONS: These data indicate that HGS is a more useful functional measure than 5m when added to a hospital nutrition assessment. Determination of HGS cutpoints to identify low strength in acute care patients will promote its use. PMID- 30288777 TI - Focal ultrasound strikes a new tune for targeted drug delivery.

PMID- 30288779 TI - History and future challenges of the subthalamic nucleus as surgical target: Review article. AB - For many years the subthalamic nucleus had a poor reputation among neurosurgeons as a result of the acute movement disorders that develop after its lesion or manipulation through different surgical procedures. However, this nucleus is now considered a key structure in relation to parkinsonism, and it is currently one of the preferred therapeutic targets for Parkinson's disease. The implication of the subthalamic nucleus in the pathophysiology of chorea and in the parkinsonian state is thought to be related to its role in modulating the basal ganglia, a fundamental circuit in movement control. Indeed, recent findings have renewed interest in this anatomical structure. Accordingly, this review aims to present a history of the subthalamic nucleus, evolving from the classic surgical concepts associated with the avoidance of this structure, to our current understanding of its importance based on findings from more recent models. Future developments regarding the relationship of the subthalamic nucleus to neuroprotection are also discussed in this review. (c) 2018 International Parkinson and Movement Disorder Society.

AB - BACKGROUND: The p.A53T point mutation in the alpha-synuclein gene (SNCA) is a rare but highly relevant cause of autosomal dominant Parkinson's disease (PD). OBJECTIVES: The objective of this study was to assess striatal dopaminergic denervation in a cohort of symptomatic carriers of the p.A53T SNCA mutation as compared to PD patients. METHODS: Data from the Parkinson's Progression Markers Initiative database of 11 symptomatic p.A53T SNCA mutation carriers who underwent 123I-FP-CIT SPECT [(123) I-2beta-carbomethoxy-3beta-(4-iodophenyl)-N-(3 fluoropropyl) nortropane single photon emission computed tomography] imaging at our site were compared with those of 33 age-, sex-, and disease duration-matched PD patients. RESULTS: The p.A53T mutation carriers had significantly lower caudate nucleus binding ratio both contralaterally and ipsilaterally to the most affected side (P = .002 and P = .006) and a decreased contralateral caudate/putamen signal ratio (P = .007) as compared to PD. A similar degree of striatal asymmetry was observed in both subgroups. No correlation between scores in neuropsychological tests and caudate nucleus dopaminergic denervation could be demonstrated. CONCLUSIONS: PD patients harboring the p.A53T SNCA mutation show evidence of a more severe nigrostriatal denervation, especially evident in the caudate nucleus. The lack of significant differences in the putaminal binding ratios may reflect a floor effect or a true preferential targeting of the caudate terminals in p.A53T SNCA-associated PD.

RESULTS: At 20 years of follow-up, control was seen in all on acromegaly-specific medication (n = 12) and 75% of those off medication (3/4). Time for 50% to achieve control on medication was 3 years, and 7.4 years off medication. Median marginal radiation dose was 27.5 Gy, and median follow-up was 166.5 months. 53% of patients developed new hypopituitarism at a median follow-up of 146 months, and the development of first onset of hypopituitarism occurred as late as 20 years after treatment. With MRI planning, no other complications were noted. Three patients underwent subsequent TSS due to poor biochemical control. During follow-up, 7 patients died at a median age of 65 years. There were no STRS related deaths. CONCLUSION: This is the longest follow-up of patients who have undergone primary STRS for acromegaly. It shows low morbidity, but significant latency to biochemical control and new-onset hypopituitarism. This mandates very long-term follow-up for these patients. STRS has shown good long-term efficacy providing initial control can be afforded by optimal medical management. While TSS remains best practice, STRS offers an alternative for those in whom surgery is not an option. PMID- 30288783 TI - JMFT Annual Report 2017. PMID- 30288784 TI - Faust, J. (2017).

PMID- 30288786 TI - Oxidative stress in hemodialysis: Causative mechanisms, clinical implications, and possible therapeutic interventions. AB - Oxidative stress (OS) is the result of prooxidant molecules overwhelming the antioxidant defense mechanisms. Hemodialysis (HD) constitutes a state of elevated inflammation and OS, due to loss of antioxidants during dialysis and activation of white blood cells triggering production of reactive oxygen species. Dialysis vintage, dialysis methods, and type and condition of vascular access, biocompatibility of dialyzer membrane and dialysate, iron administration, and anemia all can play a role in aggravating OS, which in turn has been associated with increased morbidity and mortality. Oral or intravenous administration of antioxidants may detoxify the oxidative molecules and at least in part repair OS mediated tissue damage. Lifestyle interventions and optimization of a highly biocompatible HD procedure might ameliorate OS development in dialysis.

AB - BACKGROUND: To evaluate the analytical performance of five commercial acetaminophen assays and select the best method for routine use. METHODS: Imprecision, accuracy, linearity, and interferences of three enzymatic assays (Beckman Coulter AU Paracetamol, Abbott MULTIGENT Acetaminophen, and Sekisui Acetaminophen L3K) and two immunoassay-based assays (Beckman Coulter SYNCHRON ACTM (Acetaminophen) Reagent and Siemens SYVA Emit-tox Acetaminophen) were evaluated on a Beckman Coulter AU680 chemistry analyzer. Hook effect for immunoassay-based assays and recovery in ultrafiltrate for enzymatic methods were studied. RESULTS: Within-run and between-run imprecision of the enzymatic assays ranged 0.26%-0.82% and 0.53%-2.86%, respectively, while that for the immunoassay based methods ranged 0.96%-6.34% and 1.50%-11.33%, respectively. All assays except the SYNCHRON assay fell within the program analytical performance specifications (+/-20 umol/L or 10%) for external quality assurance (EQA) samples, with the highest positive bias (31.7%) observed in the SYNCHRON assay. Icteric interference was demonstrated most significantly in the Abbott assay (up to 88 MUmol/L positive bias in blank serum). The lipemic interference on the SYNCHRON was significant (up to 110% positive bias at level of 100 MUmol/L). The immunoassay-based methods were less susceptible to hemolytic interference, while the Abbott and AU assays were more susceptible to N-acetylcysteine interference. Both immunoassay-based methods showed no hook effect up to 18 000 MUmol/L. Ultrafiltration recoveries for enzymatic methods were satisfactory, ranging from 80.0% +/- 5.1% to 89.5% +/- 3.0%. CONCLUSIONS: Proportional bias was observed in the SYNCHRON assay, while the Siemens and Sekisui assays were minimally affected by bilirubin interferences. PMID- 30288788 TI - Evaluation of the treatment costs and duration of topical treatments for multiple actinic keratosis based on the area of the cancerization field and not on the number of lesions. AB - BACKGROUND: The cost of topical treatments for actinic keratosis (AK) has historically been evaluated in relation to the number of lesions requiring treatment or simply by the price of a single tube/sachet of the drug used. OBJECTIVE: To demonstrate a new method of costing topical treatments in AK, which takes into account the actual cancerization area treated. METHODS: In order to evaluate the actual cost of each treatment, the official approval status of the drug was used to estimate the amount of cream needed per one cm2 . This value was then applied to the hypothetical cancerization area sizes to demonstrate the impact of the size treated on the actual cost of treatment. The price considered was the ex-factory price in Italy. RESULTS: Areas which could be treated with a single tube/sachet of Metvix(r) , Picato(r) , Aldara(r) , Solaraze(r) and Zyclara(r) were 200, 25, 25, 33.3 and 200 cm2 , respectively. For the treatment of smaller areas (<100 cm2 ), treatment with Metvix(r) was the most costly topical option in Italy. However, for the treatment of cancerization areas larger than 100 cm2 , Metvix(r) was the least expensive treatment option. Treatment with Metvix(r) was least long, requiring a single day of treatment for an area of up to 200 cm2 , compared with up to 224 days of treatment with Aldara(r) for the treatment of a similar size. CONCLUSION: Changing treatment costing strategy in the management of multiple AKs towards costing per cancerization area instead of costing per lesion is a much more accurate representation of the 'real world cost' for AK.

AB - Chimeric antigen receptor (CAR)-T cells are one of the impressive recent success stories of anti-cancer immunotherapy. Especially in haematological malignancies, this treatment strategy has shown promising results leading to the recent approval of two CAR-T cell constructs targeting CD19 in the United States and the European Union. After the huge success in haematological cancers, the next step will be the evaluation of its efficacy in different solid tumors, which is currently investigated in preclinical as well as clinical settings. A commonly examined tumor model in the context of immunotherapy is melanoma, since it is known for its immunogenic features. However, the first results of CAR-T cell therapy in solid tumors did not reveal the same impressive outcomes that were observed in haematological malignancies, as engineered cells need to cope with several challenges. Obstacles include the lack of migration of CAR-T cells from blood vessels to the tumor site as well as the immunosuppressive tumor microenvironment within solid tumors. Another hurdle is posed by the identification of an ideal target antigen to avoid on-target/off-tumor toxicities. Regarding immune escape mechanisms, which can be developed by tumor cells to bypass immune recognition, the observation of antigen loss should also be considered. This article gives an overview of the challenges displayed in CAR T cell therapy for the use in solid tumors and discusses different new strategies and approaches that deal with these problems in order to improve CAR-T cell therapy, particularly for its use in melanoma.

PMID- 30288791 TI - Network analysis of symptoms in a Parkinson patient using experience sampling data: An n = 1 study. AB - BACKGROUND: Around 50% of Parkinson's disease patients experience motor fluctuations after long-term treatment with levodopa. These fluctuations may be accompanied by mood fluctuations. Routine cross-sectional assessments cannot capture the extent of these motor and mood fluctuations and their possible associations. Experience sampling techniques that use frequently repeated measurements of symptoms over time are able to capture such fluctuations. Based on such data, longitudinal associations between symptoms can be studied using network analysis. AIM: The purpose of this study is to identify longitudinal associations between motor symptoms and mood states in a patient with Parkinson's disease. METHODS: A 53-year-old man with Parkinson's disease and motor fluctuations collected experience sampling data during 34 consecutive days. A set of dependent variables included tremor, rigidity, balance problems, and "on/off" state, and the mood variables anxiety, cheerful, and "down." Independent variables were the same variables assessed at the preceding measurement. Regression coefficients were calculated and presented in a network graph. RESULTS: In this patient, anxiety and cheerfulness had a central position within the symptom network. Higher anxiety was prospectively associated with increased rigidity and tremor and with feeling "down." Cheerfulness was associated with less tremor. Balance problems were not influenced by cheerfulness nor anxiety, but increased balance problems were associated with reduced cheerfulness at the next assessment. Feeling "down" did not influence self-reported motor symptom severity at the next assessment. CONCLUSION: This n = 1 study shows that network analysis of experience sampling data may reveal longitudinal associations of self reported motor symptoms and mood states that may have relevance for treatment strategies.

AB - To improve our understanding of chlorine chemistry indoors, reactive chlorine species such as hydrogen chloride (HCl) must be analyzed using fast time-response measurement techniques. Although well studied outdoors, sources of HCl indoors are unknown. In this study, mixing ratios of gaseous HCl were measured at 0.5 Hz in the indoor environment using a cavity ring-down spectroscopy (CRDS) instrument. The CRDS measurement rate provides a major advance in observational capability compared to other established techniques. Measurements of HCl were performed during three types of household activities: (a) floor exposure to bleach, (b) chlorinated and nonchlorinated detergent use in household dishwashers, and (c) cooking events. Surface application of bleach resulted in a reproducible increase of 0.1 ppbv in the affected room. Emissions of HCl from automated dishwashers were observed only when chlorinated detergents were used, with additional HCl emitted during the drying cycle. Increased mixing ratios of HCl were also observed during meal preparation on an electric element stovetop. These observations of HCl derived from household activities indicate either direct emission or secondary production of HCl via chlorine atoms is possible. Calculations of photolysis rate constants of chlorine atom precursors provide evidence that photolysis may contribute to indoor HCl levels. PMID- 30288794 TI - Magnetic resonance-guided focused ultrasound thalamotomy for treatment of essential tremor: A 2-year outcome study. AB - BACKGROUND: Magnetic resonance-guided focused ultrasound is an emerging, minimally invasive thermoablation technique for medically refractory essential tremor. Beyond the initial year, data regarding efficacy and potential predictors of efficacy are still preliminary. OBJECTIVES: The objective of this study was to assess the outcome at 2 years and the association between lesion volume and outcome 1 year after treatment. METHODS: We reviewed data from 37 patients who underwent unilateral magnetic resonance-guided focused ultrasound thalamotomy, with primary outcome being dominant tremor subscore of the Clinical Rating Scale for Tremor. We used multivariable linear regression to model initial lesion volume with 1-year outcome, adjusting for other clinically relevant variables. RESULTS: Although we detected a trend in loss of clinical benefit within the first year, the dominant tremor score at 2 years continued to be significantly improved (43.4%, 95% confidence interval 27.8%-59.0%) from baseline. Secondarily, initial lesion volume is significantly associated with 1-year outcome. CONCLUSION: Our findings show that magnetic resonance-guided focused ultrasound thalamotomy results in sustained tremor reduction for medically refractory essential tremor even in the long term, and we highlight areas for improvement.

AB - BACKGROUND: Federally Qualified Health Centers (FQHCs) deliver care to 26 million Americans living in underserved areas, but few offer telemental health (TMH) services. The social missions of FQHCs and publicly funded state medical schools create a compelling argument for the development of TMH partnerships. In this paper, we share our experience and recommendations from launching TMH partnerships between 12 rural FQHCs and 3 state medical schools. EXPERIENCE: There was consensus that medical school TMH providers should practice as part of the FQHC team to promote integration, enhance quality and safety, and ensure financial sustainability. For TMH providers to practice and bill as FQHC providers, the following issues must be addressed: (1) credentialing and privileging the TMH providers at the FQHC, (2) expanding FQHC Scope of Project to include telepsychiatry, (3) remote access to medical records, (4) insurance credentialing/paneling, billing, and supplemental payments, (5) contracting with the medical school, and (6) indemnity coverage for TMH. RECOMMENDATIONS: We make recommendations to both state medical schools and FQHCs about how to overcome existing barriers to TMH partnerships. We also make recommendations about changes to policy that would mitigate the impact of these barriers. Specifically, we make recommendations to the Centers for Medicare and Medicaid about insurance credentialing, facility fees, eligibility of TMH encounters for supplemental payments, and Medicare eligibility rules for TMH billing by FQHCs. We also make recommendations to the Health Resources and Services Administration about restrictions on adding telepsychiatry to the FQHCs' Scope of Project and the eligibility of TMH providers for indemnity coverage under the Federal Tort Claims Act. PMID- 30288799 TI - Position statement: topical calcineurin inhibitors in atopic dermatitis. AB - BACKGROUND: Atopic dermatitis (AD) is a common inflammatory skin disease in both adults and children. Whilst topical calcineurin inhibitors (TCIs), tacrolimus ointment and pimecrolimus cream, have proven efficacy for the treatment of AD, it is important to involve experts to obtain their opinion on its optimal treatment. OBJECTIVE: Using a modified Delphi approach, this project aimed to generate consensus amongst experts on the use of TCIs in the treatment of AD, with a focus on the differentiation between tacrolimus and pimecrolimus. METHODS: Six expert dermatologists from different European countries participated in this project based on their experience with AD and its treatment, which was evaluated by literature analysis and expert opinion. Consensus amongst the experts was generated using a modified Delphi approach, consisting of three distinct phases, during which a web meeting (June 2017), two online rounds of blinded Delphi voting (July-September 2017) and a face-to-face meeting (November 2017) were conducted. The consensus statements concerned two main topics: (i) Background of AD; and (ii) TCIs in AD. Hot topics in the treatment of AD not supported by meta analysis, clinical trials or large observational studies were also discussed based on clinical experience. RESULTS: In total, 25 consensus statements were defined and validated: eight statements on the general background of AD and 17 statements on the use of TCIs in AD, including their mechanism of action and therapeutic indications in AD, efficacy in adult and paediatric AD patients, pharmacokinetics, incidence of adverse events and safety concerns. Hot topics on the use of TCIs for the treatment of AD included cream vs. ointment, dosages, TCIs contact allergy, burning sensation management, superinfection and vaccination concerns. CONCLUSION: Topical calcineurin inhibitors are a suitable therapy for AD, and selection of the specific TCI should be based on factors which differentiate tacrolimus from pimecrolimus. PMID- 30288800 TI - A Porous Cobalt Tetraphosphonate Metal-Organic Framework: Accurate Structure and Guest Molecule Location Determined by Continuous-Rotation Electron Diffraction. AB - Single-crystal electron diffraction has shown to be powerful for structure determination of nano- and submicron-sized crystals that are too small to be studied by single-crystal X-ray diffraction. However, it has been very challenging to obtain high quality electron diffraction data from beam sensitive crystals such as metal-organic frameworks (MOFs). It is even more difficult to locate guest species in the pores of MOF crystals. Here, we present synthesis of a novel porous cobalt MOF with 1D channels, [Co2 (Ni-H4 TPPP)]?2 DABCO?6 H2 O, (denoted Co-CAU-36; DABCO=1,4-diazabicyclo[2.2.2]octane), and its structure determination using continuous rotation electron diffraction (cRED) data. By combining a fast hybrid electron detector with low sample temperature (96 K), high resolution (0.83-1.00 A) cRED data could be obtained from eight Co-CAU-36 crystals. Independent structure determinations were conducted using each of the eight cRED datasets. We show that all atoms in the MOF framework could be located. More importantly, we demonstrate for the first time that organic molecules in the pores, which were previously difficult to find, could be located using the cRED data. A comparison of eight independent structure determinations using different datasets shows that structural models differ only on average by 0.03(2) A for the framework atoms and 0.10(6) and 0.16(12) A for DABCO and water molecules, respectively.

AB - Imide-functionalized pi-conjugated polymer semiconductors have received great deal of interests owing to their unique physicochemical properties and optoelectronic characteristics, including excellent solubility, highly planar backbones, widely tunable bandgaps and energy levels of frontier molecular orbitals, and good film morphology. The organic electronics community has witnessed rapid expansion of materials library and remarkable improvement of device performance recently. This review summarizes the development of imide functionalized polymer semiconductors as well as their device performance in organic thin-film transistors and polymer solar cells, mainly achieved in the past three years. The materials mainly cover naphthalene diimide, perylene diimide, and bithiophene imide, and other type imide based polymer semiconductors are also discussed. The perspective offers our insights for developing new imide functionalized building blocks and polymer semiconductors with optimized optoelectronic properties. We hope that this review will generate more research interests in the community to realize further improved device performance by developing new imide-functionalized polymer semiconductors.

AB - OBJECTIVES: This exploratory study examined pain management practices among American Indians and Alaska Natives in the service area of a rural tribal clinic in Southern California. METHODS: Researchers invited 325 individuals to complete an anonymous survey in clinic waiting rooms and tribal gatherings. Analyses of the 295 eligible responses included calculating frequencies and conducting multiple logistic regressions and a Mantel-Haenszel analysis. RESULTS: Among respondents in this study, being male, younger, and having less education were strong predictors for riskier methods for managing pain. CONCLUSIONS: Understanding the methods individuals use to manage pain in a rural setting constitute a stepping-stone to develop strategies for reducing and preventing misuse and abuse of prescription medications and other drugs in rural American Indian and Alaska Native communities. PMID- 30288804 TI - Survival rates among Parkinson's disease patients who carry mutations in the LRRK2 and GBA genes. AB - BACKGROUND: The G2019S mutation in the LRRK2 gene generates a milder PD phenotype compared with GBA-PD; however, genetic based survival studies are lacking. OBJECTIVES: To compare mortality rates between LRRK2-PD, GBA-PD, and idiopathic PD patients (iPD). METHODS: Patients were screened for the G2019S mutation in the LRRK2 gene and the seven common GBA mutations among Ashkenazi Jews, classified as mild and severe (mGBA, sGBA). Motor symptoms onset and date of death were ascertained, with mortality rates calculated for each group of patients. RESULTS: Overall, 380 of 1,086 idiopathic PD patients, 49 of 159 LRRK2-PD, 56 of 148 mGBA PD, and 13 of 49 sGBA-PD participants died by the time of analysis. LRRK2-PD tended to have longer survival compared to idiopathic PD whereas GBA status did not affect mortality. Genetic status did not predict mortality in a multivariate analysis. CONCLUSION: Survival of patients with PD does not seem to be related to GBA status, whereas LRRK2 might confer higher survival rates.

AB - PURPOSE: Few studies have examined telehealth use among rural Medicaid beneficiaries. This study produced a descriptive overview of telehealth use in 2011, including the prevalence of telehealth use among rural and urban Medicaid beneficiaries, characteristics of telehealth users, types of telehealth services provided, and diagnoses associated with telehealth use. METHODS: Using data from the 2011 Medicaid Analytic eXtract (MAX), we conducted bivariate analyses to test the associations between rurality and prevalence and patterns of telehealth use among Medicaid beneficiaries. FINDINGS: Rural Medicaid beneficiaries were more likely to use telehealth services than their urban counterparts, but absolute rates of telehealth use were low-0.26% of rural nondual Medicaid beneficiaries used telehealth in 2011. Psychotropic medication management was the most prevalent use of telehealth for both rural and urban Medicaid beneficiaries, but the proportion of users who accessed nonbehavioral health services through telehealth was significantly greater as rurality increased. Regardless of telehealth users' residence, mood disorders were the most common reason for obtaining telehealth services. As rurality increased, significantly higher proportions of telehealth users received services to address attention deficit/hyperactivity disorder (ADHD) and other behavioral health problems usually diagnosed in childhood. CONCLUSIONS: These findings provide a baseline for further policy-relevant investigations including examinations of changes in telehealth use rates in Medicaid since 2011. Reimbursement policies and unique rural service needs may account for the observed differences in rural-urban Medicaid telehealth use rates. PMID- 30288809 TI - Effects of health-related quality of life on health service utilisation in patients with colorectal neoplasms. AB - This study was to assess the impact of HRQOL on health service utilisation using four different count data models. The HRQOL was measured using the Short-Form Six Dimension instrument and the functional assessment of cancer therapy-colorectal whereas health service utilisation was measured by the number of monthly clinical consultations and the number of monthly hospitalisation. Different count data models (Poisson's regression, negative binomial regression, zero-inflated Poisson's regression and zero-inflated negative binomial regression) were used to assess the association between HRQOL and health service utilisation. A performance comparison was made between the models. Goodness-of-fit statistics (the Pearson's chi-squared test statistic, the Akaike and Bayesian information criteria) were used to determine the best-fitting model. The negative binomial model performed the best in assessing the association between HRQOL measures and health service utilisation in patients with colorectal neoplasm and thus recommended. Physical well-being of patients was negatively and significantly associated with the monthly rate of health service utilisation after controlling for patient demographics. Both physical and function well-beings of patients were negatively and significantly associated with the number of monthly hospitalisations. If the data for the condition-specific FACT-C are not available, SF-6D showed a very strong negative relationship with health service utilisation. Such models can be used to guide the allocation of clinical resources and funding for the care of colorectal cancer patients.

AB - BACKGROUND: CD16 was previously suggested to be a new marker of basophils that is subject to downregulation by FcepsilonRI crosslinking. Certain compounds, including supraoptimal concentrations of the PKC inhibitors, bisindolylmaleimides, decouple the release of granules containing CD203c, CD63 and histamine, and may thus help to identify the mechanisms related to the CD16 externalization. OBJECTIVE: We hypothesized that CD16 is differentially expressed on the surface of basophils in patients with birch pollen or insect venom allergy and is subject to a regulation in response to allergens. We also employed CD203c and CD63 externalization decoupling by bisindolylmaleimides. METHODS: We performed a basophil activation test coupled with CD16 and histamine detection using cells isolated from patients with allergy to birch pollen or insect venom and negative controls. We employed two PKC inhibitors, bisindolylmaleimide II and Ro 31-8220 at their supraoptimal concentrations and, after difficulties reproducing previously published data, we analyzed the fluorescence of these inhibitors alone. We identified the CD16 isoforms by sequencing nested RT-PCR amplicons from flow cytometry sorted basophils and by cleaving the CD16b GPI anchor using a phospholipase C. RESULTS: We provide the first evidence that CD16a is expressed as a surface antigen on a small subpopulation of human basophils in patients with respiratory and insect venom allergy, and this antigen shows increased surface expression following allergen challenge or FcepsilonRI crosslinking. We rejected the apparent decoupling of the surface expression of basophil activation markers following the administration of bisindolylmaleimides. CONCLUSIONS & CLINICAL RELEVANCE: The inclusion of alphaCD16 in negative selection cocktails selects against a subset of basophils that are CD16+ or CD16dim . Using CD16dim basophils and unstained leucocytes, we show that previous studies with supraoptimal concentrations of bisindolylmaleimides are likely flawed and are not associated with the differential expression of CD203c and CD63. PMID- 30288811 TI - Kidney function during pregnancy: a systematic review and meta-analysis. AB - OBJECTIVES: To systematically review current literature on kidney function changes during pregnancy, to estimate the extent of adaptation over the course of both healthy physiological and hypertensive complicated singleton pregnancies and to determine healthy pregnancy reference values. METHODS: A meta-analysis was performed following a systematic review of current literature on kidney function during uncomplicated and complicated pregnancies. PubMed (NCBI) and Embase (Ovid) electronic databases were used for the literature search, which was performed from inception to July 2017. Studies were required to report a non-pregnant reference value of kidney function (either non-pregnant control group, pre pregnancy or postpartum measurement) and a pregnancy measurement during a predetermined and reported gestational age. Pooled mean differences between pregnancy measurements and reference value were calculated for predefined intervals of gestational age using a random-effects model described by DerSimonian and Laird. RESULTS: Twenty-nine studies were included with publication dates ranging from 1958 to 2016. As early as the first trimester, glomerular filtration rate (GFR) increases, up until 40 - 50% during physiologic pregnancy when compared to non-pregnant conditions. Inulin clearance was highest at 36 - 41 weeks with a 55.6% increase (? 53.7 ml/min CI 44.7 - 62.6), and creatinine clearance at 15 - 21 weeks with a 37.6% increase (?36.6 ml/min CI 26.2 - 46.9). Serum creatinine values decrease was most prominent at 15-21 weeks with a 23.2 % decrease (? -0.19 mg/dl (CI -0.23 - -0.15) compared to non-pregnant conditions. The meta-regression analysis, containing eight studies on complicated pregnancies, showed a significant difference in for all kidney function parameters when comparing uncomplicated to complicated gestation. CONCLUSIONS: In healthy pregnancy, GFR accelerates as early as the first trimester and remains to function at a higher rate throughout gestation. In contrast, kidney function is decreased in hypertensive gestation. This article is protected by copyright. All rights reserved. PMID- 30288813 TI - The relationship between cannabis use and diabetes: Results from the National Epidemiologic Survey on Alcohol and Related Conditions III. AB - INTRODUCTION AND AIMS: The relationship between cannabis use and diabetes is puzzling. Although cannabis users versus non-users should theoretically have a higher likelihood of diabetes, epidemiological studies suggest otherwise. However, previous epidemiological studies have not considered the potential confounding effects of mental health disorders. As such, the relationship between cannabis use and diabetes was examined while accounting for a range of potential confounders, including mental health disorders. DESIGN AND METHODS: Data were obtained from the National Epidemiologic Survey on Alcohol and Related Conditions III. Chi-square tests were used to compare socio-demographics, lifestyle behaviours, physical health disorders and mental health disorders between diabetics and non-diabetics. Measures that exhibited statistical significance in these tests were subsequently included in multiple logistic regression analyses to quantify the relationships between lifetime and 12-month cannabis use and diabetes. RESULTS: Although there was a considerable attenuation in the magnitude of the odds ratios after adjustment for confounders, there was still a decreased likelihood of diabetes for cannabis users versus non-users. The corresponding odds ratios of diabetes were 0.81 (95% confidence interval 0.70, 0.94) and 0.51 (95% confidence interval 0.41, 0.63) for lifetime and 12-month cannabis use, respectively. DISCUSSION AND CONCLUSIONS: A decreased likelihood of diabetes for cannabis users versus non-users was indicated after accounting for a range of potential confounders, including mental health disorders. Before the protective effects of cannabis use for diabetes can be suggested, further epidemiological studies are needed that incorporate prospective designs, as well as feature innovative exposure measurements and statistical analyses. PMID- 30288812 TI - Position Statement: Linear prurigo is a subtype of chronic prurigo. AB - BACKGROUND: Chronic prurigo (CPG) is a distinct disease characterized by chronic pruritus, history and/or signs of prolonged scratching and multiple pruriginous lesions. It may present with various clinical manifestations, including papules, nodules, plaques or umbilicated lesions. Some patients with chronic pruritus show pruriginous linear and scaring scratch lesions (LSSL) and it is unclear whether these lesions belong to the spectrum of CPG. OBJECTIVE: To achieve a consensus on the classification of pruriginous LSSL and establish criteria to differentiate them from similar appearing conditions of different nature. METHODS: Members of the Task Force Pruritus (TFP) of the European Academy of Dermatology and Venereology participated in the consensus conference, discussing representative clinical cases. Using the Delphi method, consensus was reached when >=75% of members agreed on a statement. RESULTS: Twenty-one members of the TFP with voting rights participated in the meeting. It was consented that LSSL occurs due to chronic pruritus and prolonged scratching, and share common pathophysiological mechanisms with CPG. LSSL were thus considered as belonging to the spectrum of CPG and the term 'linear prurigo' was chosen to describe this manifestation. CONCLUSION: Considering linear prurigo as belonging to the spectrum of CPG has important clinical implications, since both the diagnostic and therapeutic approach of these patients should be performed as recommended for CPG. Importantly, linear prurigo should be differentiated from self-inflicted skin lesions as factitious disorders or skin picking syndromes.

AB - DnaA initiates chromosome replication in bacteria. In Caulobacter crescentus, the Lon protease degrades DnaA to coordinate replication with nutrient availability and to halt the cell cycle during acute stress. Here, we characterize the mechanism of DnaA recognition by Lon. We find that the folded state of DnaA appears crucial for its degradation, in contrast to the well-known role of Lon in degrading misfolded proteins. We fail to identify a single degradation motif (degron) sufficient for DnaA degradation, rather we show that both the ATPase domain and a species-specific N-terminal motif are important for productive Lon degradation of full-length DnaA. Mutations in either of these determinants disrupt DnaA degradation in vitro and in vivo. However, analysis of truncation products reveals that appending other extensions to the ATPase domain is sufficient to trigger degradation, suggesting plasticity in Lon recognition. Our final working model is that Lon engages DnaA through at least two elements, one of which anchors DnaA to Lon and the other acting as an initiation site for degradation.

AB - BACKGROUND: Anaphylaxis hospitalizations are increasing in many countries, in particular for medication and food triggers in young children. Food-related anaphylaxis remains an uncommon cause of death, but a significant proportion of these are preventable. AIM: To review published epidemiological data relating to food-induced anaphylaxis and potential risk factors of fatal and/or near-fatal anaphylaxis cases, in order to provide strategies to reduce the risk of severe adverse outcomes in food anaphylaxis. METHODS: We identified 32 published studies available in MEDLINE (1966-2017), EMBASE (1980-2017), CINAHL (1982-2017), using known terms and synonyms suggested by librarians and allergy specialists. RESULTS: Young adults with a history of asthma, previously known food allergy particularly to peanut/tree nuts are at higher risk of fatal anaphylaxis reactions. In some countries, cow's milk and seafood/fish are also becoming common triggers of fatal reactions. Delayed adrenaline injection is associated with fatal outcomes, but timely adrenaline alone may be insufficient. There is still a lack of evidence regarding the real impact of these risk factors and co factors (medications and/or alcohol consumption, physical activities, and mast cell disorders). CONCLUSIONS: General strategies should include optimization of the classification and coding for anaphylaxis (new ICD 11 anaphylaxis codes), dissemination of international recommendations on the treatment of anaphylaxis, improvement of the prevention in food and catering areas, and dissemination of specific policies for allergic children in schools. Implementation of these strategies will involve national and international support for ongoing local efforts in relationship with networks of centres of excellence to provide personalized management (which might include immunotherapy) for the most at-risk patients. PMID- 30288818 TI - The proof is in the bulb: glycerol influences key stages of lily development. AB - A bulb is a whole plant condensed into an underground organ. A geophyte's bulb comprises both food reserves and important developmental history that may affect its whole growth. In Easter lily (Lilium longiflorum), bulb size is associated with the plant's flowering pathway - vernalization or photoperiod - and also affects sprouting, flower quality and abortion rate. The aim of this study was to investigate the reasons for the major physiological differences between large and small bulbs. Lily bulbs start their development from secondary meristems along the stem, with large bulbs being heavier and bear more scales than small ones. Peeling the outer scales of a large bulb converts its physiological responses into those of a small bulb, implying that the physiological discrepancies in plants developing from large or small bulbs are mediated by factors inherent to the bulb. We therefore performed broad analyses of the metabolite composition in the scales of bulbs subjected to temperature regimes affecting further plant development. We found a striking association between the level of glycerol, a primary metabolite mostly synthesized in the outer scales, and a delay in sprouting and flowering time, and reduction in abortion rate. Exogenous glycerol application to the bulbs before planting corroborated these results. Moreover, transcriptome analyses showed that flowering-promoting gene expression was downregulated in the bulb after glycerol treatment, while potential flowering inhibitor as well as a dormancy-related gene expressions were upregulated. Based on these studies, we postulate that glycerol is a major factor influencing both vegetative and reproductive development in lily.

AB - In eukaryotes, alternative splicing (AS) greatly expands the diversity of transcripts. However, it is challenging to accurately determine full-length splicing isoforms. Recently, more studies have taken advantage of Pacific Bioscience (PacBio) long-read sequencing to identify full-length transcripts. Nevertheless, the high error rate of PacBio reads seriously offsets the advantages of long reads, especially for accurately identifying splicing junctions. To best capitalize on the features of long reads, we used Illumina RNA seq reads to improve PacBio circular consensus sequence (CCS) quality and to validate splicing patterns in the rice transcriptome. We evaluated the impact of CCS accuracy on the number and the validation rate of splicing isoforms, and integrated a comprehensive pipeline of splicing transcripts analysis by Iso-Seq and RNA-seq (STAIR) to identify the full-length multi-exon isoforms in rice seedling transcriptome (Oryza sativa L. ssp. japonica). STAIR discovered 11 733 full-length multi-exon isoforms, 6599 more than the SMRT Portal RS_IsoSeq pipeline did. Of these splicing isoforms identified, 4453 (37.9%) were missed in assembled transcripts from RNA-seq reads, and 5204 (44.4%), including 268 multi exon long non-coding RNAs (lncRNAs), were not reported in the MSU_osa1r7 annotation. Some randomly selected unreported splicing junctions were verified by polymerase chain reaction (PCR) amplification. In addition, we investigated alternative polyadenylation (APA) events in transcripts and identified 829 major polyadenylation [poly(A)] site clusters (PACs). The analysis of splicing isoforms and APA events will facilitate the annotation of the rice genome and studies on the expression and polyadenylation of AS genes in different developmental stages or growth conditions of rice. PMID- 30288820 TI - Transcriptional effects of cadmium on iron homeostasis differ in calamine accessions of Noccaea caerulescens. AB - Calamine accessions of the zinc/cadmium/nickel hyperaccumulator, Noccaea caerulescens, exhibit striking variation in foliar cadmium accumulation in nature. The Ganges accession (GA) from Southern France displays foliar cadmium hyperaccumulation (>1000 MUg g-1 DW), whereas the accession La Calamine (LC) from Belgium, with similar local soil metal composition, does not (<100 MUg g-1 DW). All calamine accessions are cadmium hypertolerant. To find out the differences between LC and GA in their basic adaptation mechanisms, we bypassed the cadmium excluding phenotype of LC by exposing the plants to 50 MUm cadmium in hydroponics, achieving equal cadmium accumulation in the shoots. The iron content increased in the roots of both accessions. GA exhibited significant decreases in manganese and zinc contents in the roots and shoots, approaching those in LC. Altogether 702 genes responded differently to cadmium exposure between the accessions, 157 and 545 in the roots and shoots, respectively. Cadmium-exposed LC showed a stress response and had decreased levels of a wide range of photosynthesis-related transcripts. GA showed less changes, mainly exhibiting an iron deficiency-like response. This included increased expression of genes encoding five iron deficiency-regulated bHLH transcription factors, ferric reduction oxidase FRO2, iron transporters IRT1 and OPT3, and nicotianamine synthase NAS1, and decreased expression of genes encoding ferritins and NEET (a NEET family iron-sulfur protein), which is possibly involved in iron transfer, distribution and/or management. The function of the IRT1 gene in the accessions was compared. We conclude that the major difference between the two accessions is in the way they cope with iron under cadmium exposure.

PMID- 30288821 TI - Early-life exposure to sibling modifies the relationship between CD14 polymorphisms and allergic sensitization. AB - BACKGROUND: Markers of microbial exposure are thought to be associated with risk of allergic sensitization; however, the associations are inconsistent and may be related to gene-environment interactions. OBJECTIVE: To examine the relationship between polymorphisms in the CD14 gene and allergic sensitization and whether sibling exposure, as a marker of microbial exposure, modified this relationship. METHODS: We used data from the Tasmanian Longitudinal Health Study and the Melbourne Atopy Cohort Study. Two CD14 polymorphisms were genotyped. Allergic sensitization was defined by a positive response to a skin prick test. Sibling exposure was measured as cumulative exposure to siblings before age 6 months, 2 and 4 years. Logistic regression and multi-level mixed-effects logistic regression were used to examine the associations. Effect estimates across the cohorts were pooled using random-effects meta-analysis. RESULTS: CD14 SNPs were not individually associated with allergic sensitization in either cohort. In TAHS, cumulative sibling exposure before age 6 months, 2 and 4 years was each associated with a reduced risk of allergic sensitization at age 45 years. A similar effect was observed in MACS. Meta-analysis across the two cohorts showed consistent evidence of an interaction between cumulative sibling exposure before 6 months and the rs5744455-SNP (P = 0.001) but not with the rs2569190-SNP (P = 0.60). The pooled meta-analysis showed that the odds of sensitization with increasing cumulative exposure to sibling before 6 months of age was 20.9% smaller in those with the rs5744455-C-allele than the T-allele (OR = 0.83 vs 1.05, respectively). CONCLUSION AND CLINICAL RELEVANCE: Cumulative sibling exposure reduced the risk of sensitization from childhood to middle age in genetically susceptible individuals.

AB - AIM: The Baby Moves smartphone application is designed for parents to video their infants' spontaneous movement for remote General Movements Assessment (GMA). We aimed to assess the engagement with Baby Moves amongst high- and low-risk infants' families and the socio-demographic variables related to engagement. METHODS: Families of extremely preterm (EP; <28 weeks' gestational age) or extremely low-birthweight (ELBW; <1000 g) infants and term-born controls from a state-wide geographical cohort study were asked to download Baby Moves. Baby Moves provided reminders and instructions to capture videos of their infants' general movements. Parents were surveyed about Baby Moves' usability. RESULTS: The parents of 451 infants (226 EP/ELBW; 225 control) were recruited; 416 (204 EP/ELBW; 212 control) downloaded Baby Moves, and 346 (158 EP/ELBW; 188 control) returned at least one scorable video for remote GMA. Fewer EP/ELBW families submitted a scorable video than controls (70 vs. 83%, respectively; odds ratio (OR) 0.48, 95% confidence interval (CI) 0.3-0.79, P = 0.003), but the difference diminished when adjusted for socio-demographic variables (OR 1.09, 95% CI 0.59 2.0, P = 0.79). Families who received government financial support (OR 0.28, 95% CI 0.1-0.78, P = 0.015), who spoke limited English at home (OR 0.39, 95% CI 0.22 0.69, P = 0.001) or with lower maternal education (OR 0.38, 95% CI 0.21-0.68, P = 0.001) were less likely to return a scorable video. Surveyed parents responded mostly positively to Baby Moves' usability. CONCLUSIONS: Most parents in this study successfully used Baby Moves to capture infant movements for remote GMA. Families of lower socio-demographic status used Baby Moves less. PMID- 30288824 TI - Cutaneous diphtheria in a returned traveller. PMID- 30288825 TI - Increased risk of morbidities and health-care utilisation in children born following preterm labour compared with full-term labour: A population-based study. AB - AIM: Recent evidence is emerging indicating long-term effects in infants born after an episode of preterm labour (PTL), even if birth is at term. This population-based study compared long-term rates of outcomes and health-care utilisation (HCU) in children born following spontaneous preterm labour, irrespective of gestational age at delivery or of an uncomplicated pregnancy (SPTLu), with children born following full-term labour (FTL), overall stratified by comorbidity status and assessed using a composite morbidity measure (CM). METHODS: Retrospective data on mother-neonate pairs were collected from a patient linked dataset from the Netherlands Perinatal Registry and the PHARMO Database Network. Children born between 2000 and 2010 were followed until 2012. RESULTS: Of pregnancies in 134 006 mother-neonate pairs, 122 894 (92%) pregnancies resulted in FTL, and 11 112 (8%) resulted in PTL. Of the PTL pregnancies, 6599 (59%) were SPTLu. Mean follow-up after birth was 6.6-6.7 years. Children from SPTLu pregnancies were at increased risk of neurodevelopmental and respiratory conditions compared with those from FTL pregnancies. In children from SPTLu pregnancies, the presence of the CM was associated with an increased risk of respiratory conditions and failure to thrive. Post-natal hospitalisations (incidence rate (IR) per 100 patient-years: 18.1 vs. 11.7) and specialist referrals (IR per 1000 patient-years: 290.6 vs. 184.5) occurred significantly more frequently in children from SPTLu versus FTL pregnancies. CONCLUSION: The increased risk of morbidities and HCU in children born following SPTLu pregnancy in this population-based setting reinforces the need for safe interventions that can effectively halt labour and lead to an improvement in childhood outcomes.

PMID- 30288827 TI - Staphylococcus aureus-derived extracellular vesicles induce monocyte recruitment by activating human dermal microvascular endothelial cells in vitro. AB - BACKGROUND: Atopic dermatitis (AD) represents the most common inflammatory skin disorder in children showing massive infiltration of immune cells. The colonization of AD-afflicted skin by Staphylococcus aureus and S. aureus-derived extracellular vesicles (SEVs) has been associated with AD pathogenesis; however, the molecular mechanism underlying SEV-mediated inflammatory responses remains unclear. OBJECTIVE: We investigated how SEVs can mediate inflammatory responses in AD pathogenesis by examining the effect of SEVs on human dermal microvascular endothelia cells (HDMECs). METHODS: HDMECs were treated with SEVs, and the expression of cell adhesion molecules or cytokines was assessed using RT-qPCR, Western blot or cytokine array analyses. The receptor for SEVs and related signalling molecules in HDMECs were addressed and verified via gene knockdown or inhibitor experiments. The recruitment assay of human THP-1 monocytic cells on HDMECs was performed after SEV treatment in the presence or absence of the verified receptor or signalling molecule. RESULTS: SEVs, but not other gram positive bacteria-derived extracellular vesicles, directly activated HDMECs by increasing the expression of cell adhesion molecules (E-selectin, VCAM1 and ICAM1) and that of IL-6, the inflammatory cytokine; consequently, they enhanced the recruitment of THP-1 monocytic cells to HDMECs. The SEV-induced HDMEC activation was dependent on Toll-like receptor 4 and the NF-kappaB signalling pathway, which was rapidly activated within 1 hour post-treatment and followed by an upregulation of cell adhesion molecules and IL-6 at later time-points. Moreover, SEV-mediated HDMEC responses were more rapid and intense than those induced by the same protein concentrations of S. aureus extracts. CONCLUSIONS & CLINICAL RELEVANCE: SEVs as proinflammatory factors could mediate immune cell infiltration in AD by efficiently inducing endothelial cell activation and monocyte recruitment, which may provide insights into alleviating the S. aureus mediated onset or progression of AD and its phenotypes. PMID- 30288828 TI - Application of Box-Behnken design for ultrasound-assisted extraction and recycling preparative HPLC for isolation of anthraquinones from Cassia singueana. AB - INTRODUCTION: Cassia singueana Del. (Fabaceae) is a rare medicinal plant used in the traditional medicine preparations to treat various ailments. The root of C. singueana is a rich source of anthraquinones that possess anticancer, antibacterial and antifungal properties. OBJECTIVE: The objective of this study was to develop an ultrasound-assisted extraction (UAE) method for achieving a high extraction yield of anthraquinones using the response surface methodology (RSM), Box-Behnken design (BBD), and a recycling preparative high-performance liquid chromatography (HPLC) protocol for isolation of anthraquinones from C. singueana. METHODOLOGY: Optimisation of UAE was performed using the Box-Behnken experimental design. Recycling preparative HPLC was employed to isolate anthraquinones from the root extract of C. singueana. RESULTS: The BBD was well described by a quadratic polynomial model (R2 = 0.9751). The predicted optimal UAE conditions for a high extraction yield were obtained at: extraction time 25.00 min, temperature 50 degrees C and solvent-sample ratio of 10 mL/g. Under the predicted conditions, the experimental value (1.65 +/- 0.07%) closely agreed to the predicted yield (1.64%). The obtained crude extract of C. singueana root was subsequently purified to afford eight anthraquinones. CONCLUSION: The extraction protocol described here is suitable for large-scale extraction of anthraquinones from plant extracts.

AB - Somatic symptom disorder is a condition in which a patient's subjective report of physical symptoms is associated with distress; disruption of day-to-day functioning; or disproportionate thoughts, feelings and behaviours regarding the symptoms, whether or not they are associated with an identified medical condition. While somatic symptom disorder affects a considerable proportion of children and adolescents presenting to the emergency department (ED), it has not been well investigated in the ED literature, nor is there much formal training in, or guidelines for, how to care for affected patients in the ED. The aim of this paper is to highlight the historical clues commonly reported by these patients in order to try to help the emergency physicians recognise patients affected by a somatic symptom disorder. Adolescent age, the presence of daily subjective symptoms presenting daily for weeks or months, a long medical history record, an extensive diagnostic workup and, most of all, disproportionate functional impairment related to the symptoms are all features strongly suggestive of this disorder. Emergency physicians should become used to taking advantage of these clues to formulate a positive diagnosis of somatic symptom disorder according to the most recent diagnostic criteria. Emergency physicians have the unique opportunity to contribute to the correct diagnosis and treatment of these patients and to have a positive impact on their prognosis. PMID- 30288830 TI - Targeted ablation of specific electrogram patterns in low-voltage areas after pulmonary vein antral isolation in persistent atrial fibrillation: Termination to an organized rhythm reduces atrial fibrillation recurrence. AB - BACKGROUND: Ablation strategies have been developed to improve outcomes in patients with persistent atrial fibrillation (PsAF). However, the impact of atrial fibrillation (AF) termination on late AF recurrence is not well known. The aim of our study was to evaluate the impact of AF termination to atrial tachycardia (AT) or sinus rhythm (SR) during catheter ablation on late AF recurrence after the 3-month blanking period. METHODS AND RESULTS: We prospectively recruited 140 patients (mean age: 58.5 +/- 12.3 years old, 74.3% males) with uninterrupted PsAF of a mean duration of 3.7 months. Pulmonary vein antral isolation (PVAI) was the first ablation step, and if AF did not terminate (to SR or AT), we ablated low-voltage areas less than 0.4 mV with specific electrogram characteristics. We successfully converted AF to AT or SR in 56 patients (40%) during PVAI (n = 24) or low-voltage ablation ( n = 32). The remaining 84 patients (60%) were electrically cardioverted to SR at the end of the procedure. One hundred patients (71.4%) maintained SR after a single procedure during a mean follow-up of 21.1 +/- 0.8 months. Of the 56 patients with AF termination, 46 (82.1%) had no recurrence, while in the group of 84 patients without AF termination, 54 patients (64.3%) remained in SR ( P < 0.02). CONCLUSION: Ablation of PVAI and specific electrograms in low-voltage areas less than 0.4 mV can lead to encouraging outcomes with a low recurrence rate as well as a lower need for redo procedures. PMID- 30288832 TI - ZFAS1: A novel vital oncogenic lncRNA in multiple human cancers. AB - Long noncoding RNAs (lncRNAs) are a class of noncoding, endogenous, single stranded RNAs longer than 200 nucleotides in length that are transcribed by RNA polymerase II. Mounting evidence has indicated that lncRNAs play key roles in several physiological and pathological processes by modifying gene expression at the transcriptional, posttranscriptional, epigenetic, and translation levels. Many reports have demonstrated that lncRNAs function as potential oncogene or tumour suppressors and thus play vital regulatory roles in tumourigenesis and tumour progression. ZNFX1 antisense RNA 1 (ZFAS1), a novel lncRNA transcribed in the antisense orientation of zinc finger NFX1-type containing 1(ZNFX1), was found to be increased in multiple cancers, such as gastric cancer and hepatocellular carcinoma, contributing to cancer development and progression. In the present review, we summarized recent progression on study of the functions and underlying molecular mechanisms of ZFAS1 related to occurrence and development of multiple cancers. PMID- 30288833 TI - Placental histopathology in preterm fetal growth restriction. AB - AIMS: Approximately 6-9% pregnancies are affected by fetal growth restriction (FGR). Placental alterations related to utero-placental insufficiency in FGR may induce placental vascular remodelling to the detriment of the fetus. The objective of this article was to study histopathological features of placentae in a cohort of preterm growth-restricted infants in comparison to a cohort of preterm appropriately grown infants. METHODS: In a cohort of 40 preterm infants of 28-32 weeks' gestation, placental histopathology was evaluated by a histopathologist, who was blinded to the identity of the grouping. Twenty infants had FGR, while 20 were appropriate for gestational age (AGA). Predefined histopathological characteristics were assessed based on the Amsterdam Placental Workshop Group Consensus Statement. RESULTS: The gestational age and birthweight of the FGR and AGA cohorts were 29.8 +/- 1.3 versus 30 +/- 0.9 weeks, P = 0.78 and 923 +/- 168 versus 1403 +/- 237 g, <0.001, respectively. Maternal vascular malperfusion, accelerated villous maturation and fetal vascular malperfusion were features that were significantly more common in FGR placentae. CONCLUSION: Based on the results of the present study, specific placental histopathological changes may be present in FGR placentae, which may reflect the effects of utero-placental insufficiency. PMID- 30288834 TI - Needs of parents in a surgical neonatal intensive care unit. AB - AIM: While there is evidence of parental needs in the neonatal intensive care unit (NICU), parents of newborns admitted for general surgery are an under researched population. This study aimed to identify needs in parents of newborns admitted to the NICU for general surgery and whether health-care professionals meet these needs. METHODS: This was a prospective cohort study of 111 parents (57% mothers) of newborns admitted to a surgical NICU for general surgery in Australia from January 2014 to September 2015. Parents completed the Neonatal Family Needs Inventory (NFNI), comprising 56 items in five subscales (Support, Comfort, Information, Proximity, Assurance) at admission and discharge, as well as the Social Desirability Scale (SDS). Data were analysed using parametric and non-parametric techniques. RESULTS: At both admission and discharge, parents rated Assurance (M = 3.8, standard deviation (SD) = 0.24) needs as the most important, followed by Proximity (M = 3.6, SD = 0.32) and Information (M = 3.5, SD = 0.38). Mothers rated Assurance significantly more important than fathers (P < 0.02). Overall, parents' most important needs were having questions answered honestly (M = 3.96, SD = 0.19), seeing their infant frequently and knowing about the medical treatment (both M = 3.95, SD = 0.23). The 10 most important needs were met for more than 96% of parents, with no evidence of response bias. CONCLUSIONS: Reassurance is a priority need for parents in the surgical NICU. Mothers' and fathers' needs may be best met by practices based on family-centred, individualised care principles. PMID- 30288835 TI - Nurses' negative affective states, moral disengagement, and knowledge hiding: The moderating role of ethical leadership. AB - AIM: This study aims to investigate the influence of nurses' negative affective states on their knowledge-hiding behaviours through moral disengagement, and especially the moderating role of ethical leadership. BACKGROUND: Researchers have paid much attention to the harmfulness of knowledge hiding, yet the mechanisms of why and how nurses' negative affective states have an impact on their knowledge-hiding behaviours are less clear. METHOD: Two different questionnaire surveys were used in two different studies. In Study 1, a research design with three stages, including 323 nurses (64.47% response rate, 51.70% male) working in a hospital in Shanghai, China, was used. Study 2 involved 317 nurses (63.40% response rate, 51.74% male) working in five hospitals in Shanghai, China. The two studies shared the same statistical method, in which hierarchical regression analyses, the Sobel test, and bootstrap estimates were used to test hypotheses. RESULTS: We found that (a) nurses' negative affective states were positively related to their knowledge-hiding behaviours; (b) moral disengagement partially mediated this relationship in Study 1, but fully mediated it in Study 2; and (c) ethical leadership mitigated the indirect relationship between negative affective states and knowledge hiding via moral disengagement. CONCLUSION: Nurses with negative affective states are more likely to activate moral disengagement as a secondary cognitive process to make personal moral rules momentarily obscure, which, in turn, leads them to hide knowledge that is requested by other members. The above relationships will depend on the levels of ethical leadership. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers should try to reduce nurses' knowledge-hiding behaviours by addressing nurses' negative affective states, decreasing nurses' moral disengagement, and performing ethical leadership behaviours. PMID- 30288836 TI - Detailed comparison between the wall thickness and voltages in chronic myocardial infarction. AB - BACKGROUND: The relationship between the local electrograms (EGMs) and wall thickness (WT) heterogeneity within infarct scars has not been thoroughly described. The relationship between WT and voltages and substrates for ventricular tachycardia (VT) was examined. METHODS: In 12 consecutive patients with myocardial infarction and VT, WT, defined by a multidetector computed tomography, and voltage were compared. In multicomponent EGMs, amplitudes of both far- and near-field components were manually measured, and the performance of the three-dimensional-mapping system automatic voltage measurement was assessed. RESULTS: Of 15 748 points acquired, 2677 points within 5 mm of the endocardial surface were analyzed. In total, 909 (34.0%) multicomponent EGMs were identified; 785 (86.4%) and 883 (97.1%) were distributed in the WT less than 4 and 5 mm, respectively. Far-field EGM voltages increased linearly from 0.14 mV (0.08-0.28 mV) in the WT: 0 to 1 mm to 0.70 mV (0.43-2.62 mV) in the WT: 4 to 5 mm (rho = 0.430; P < 0.001), and a significant difference was demonstrated between any two WT-groups (P <= 0.001). In contrast, near-field EGM voltages varied from 0.27 mV (0.11-0.44 mV) in the WT: 0 to 1 mm to 0.29 mV (0.17-0.53 mV) in the WT: 4 to 5 mm with a poorer correlation (rho = 0.062, P = 0.04). The proportion of points where the system automatically measured the voltage on near-field EGMs increased from less than 10% in areas of WT: 4 to 5 mm to 50% in areas less than 2 mm. Of 21 VTs observed, seven hemodynamically stable VTs were mapped and terminated in WT: 1 to 4 mm area. CONCLUSIONS: Although far-field voltages gradually increase with the WT, near-field does not. The three-dimensional-mapping system preferentially annotates the near-field components in thinner areas (center of the scar) and the far-field component in thicker areas when building a voltage map. Critical sites of VT are distributed in WT: 1 to 4 mm areas. PMID- 30288837 TI - Nutritional assessment of resettled paediatric refugees in Western Australia. AB - AIM: Nutritional deprivation, inadequate diet and food insecurity are common refugee experiences. The growth and nutritional status of paediatric refugees following resettlement in developed countries and the related interplay with socio-economic factors remain less defined; this study aims to describe these features. METHODS: Standardised dietary, medical and socio-demographic health assessments of new refugee patients attending a multidisciplinary paediatric Refugee Health Service (RHS) in Western Australia between 2010 and 2015 were analysed. RESULTS: Demographic data from 1131 paediatric refugees are described (age 2 months to 17.8 years). The majority experienced socio-economic disadvantage, had limited parental education and required interpreters. Nutritional deficiencies were common but varied across ethnicities: iron deficiency (ID) (12.3%), anaemia (7.3%) and inadequate dairy intake (41.0%). A third of children (32.6%) did not consume meat. Infant breastfeeding was sustained (77.8%) in infants <12 months. Prolonged breastfeeding (44.9% aged 12 24 months) was associated with an increased risk of ID (odds ratio 4.0, 95% confidence interval 1.4-11.6). Median body mass index increased significantly for those >24 months between referral and RHS assessment (median period 1.8 months). Overall, 27.1% required additional formal dietetic follow-up, with higher nutritional concerns in refugee children <24 months compared to older patients. CONCLUSIONS: Identification of frequent post-settlement nutritional concerns has been captured through structured multidisciplinary paediatric health screening. Specific screening for socio-economic influencing factors, including education, poverty and food insecurity, during refugee clinical assessments is recommended. Development of targeted, culturally appropriate parental education resources and interventions may improve management following resettlement. Longitudinal research assessing resettlement growth trajectories is required. PMID- 30288838 TI - Coronary artery injury related to catheter ablation of cardiac arrhythmias: A systematic review. AB - INTRODUCTION: Catheter ablation (CA) has emerged as the preferred modality of treatment for many cardiac arrhythmias. Anatomical sites of ablation are often located in close proximity to coronary arteries. However, the incidence of CA related coronary injury has not been well studied. We sought to systematically evaluate all cases of CA-related coronary injuries. METHODS AND RESULTS: A PubMed search was conducted from inception until May 1, 2017 using the keywords "coronary artery" and "ablation." We identified 2817 published articles of which 43 articles met our inclusion criteria representing 61 cases of coronary artery injury attributed to CA procedures from 1992 to 2017. Posteroseptal accessory pathway ablation was associated with the highest incidence of coronary injury (35.6% of cases), followed by cavotricuspid isthmus-dependent flutter (19.3%). The right coronary artery was the site of injury in over two-thirds of all reported cases. Coronary injury was detected intraprocedurally in about half of the cases (43.1%), whereas it was a delayed presentation in the other half. Coronary intervention was performed in a third of all cases (32.7%). There were a total of three deaths attributed to coronary artery injury. CONCLUSIONS: Most (91.8%) coronary injuries are a result of anatomic proximity to the site of ablation. Awareness of the relation between coronary artery course and anatomical site of ablation could prevent myocardial damage and improve procedural safety. PMID- 30288840 TI - Intersession improvement and outcome in psychotherapy. AB - OBJECTIVE: Psychotherapy patients who experience large, stable symptomatic improvement between sessions are more likely than those without such sudden gains to benefit from treatment. However, there is limited empirical basis for the definition of sudden gains, and it is unclear how they may affect symptomatic change at other points in treatment. METHOD: In a psychotherapy training clinic, 149 adults completed a distress measure at each session. For each criterion in the definition of sudden gains, we evaluated the prediction of outcome, possible moderating variables, local score instability, and multisession change before and after score shifts. RESULTS: Large intersession improvement did not lead to increased rate of change later in treatment, but it did predict outcome, regardless of whether nearby session scores were stable. Early improvement during the first five treatment sessions was an independent predictor of outcome. Large intersession improvement generally occurred in the context of local score instability. CONCLUSION: Sudden gains appear to predict outcome because of improvement inherent in the gains themselves. Early overall improvement predicts outcome almost as effectively as do sudden gains. There may be advantages to redefining sudden gains as large intersession improvement, regardless of local score stability. PMID- 30288839 TI - Enrolment in paediatric oncology early-phase clinical trials: The health-care professionals' perspective. AB - AIM: Approximately 20-30% of children/adolescents with cancer will not respond to standard therapies. These children are usually offered experimental treatment in the form of an early-phase clinical trial. We examined the perspectives of health care professionals (HCPs) regarding obtaining informed consent for early-phase trials in paediatric oncology. METHODS: We collected survey data from 87 HCPs working in paediatric cancer centres across Australia and New Zealand. RESULTS: HCPs were, on average, 44 years old (range = 25-74), with 15.8 years' experience in paediatric oncology (range = 1-40). Few HCPs (17.4%) received training for early-phase trial consent; however, most were willing to attend training (77.9%). HCPs (61.6%) reported that they informed families about early-phase trials without any attempt to influence their decision. However, 23.3% of HCPs reported that they informed families that their child would benefit. HCPs' main obstacle in obtaining consent was their perception of parents' eagerness to 'try anything' (52.3%). HCPs perceived that many parents misunderstood key clinical trials concepts, with 25.2% of HCPs believing that not being given clear information influenced parents' decisions. Physicians were more likely than social workers/nurses to inform families that other children will benefit from enrolment in the study. Social workers/nurses appeared to rate the chance of benefits for the patient higher than physicians. CONCLUSIONS: HCPs may experience difficulty conducting early-phase trial consultations and obtaining valid informed consent. Our study highlights the need for formal training for HCPs and additional patient education tools.

AB - INTRODUCTION: Children living with parents who harmfully consume alcohol might experience more life events, in particular negative, than children living with parents who do not harmfully consume alcohol. They also primarily use less adaptive coping styles and often demonstrate lower resilience. No studies evaluated whether coping styles or psychological well-being might influence the risk of life events occurrence in children living with parents who harmfully consume alcohol. METHODS: Forty-five children living with parents who harmfully consume alcohol and 45 children living with parents who do not harmfully consume alcohol, matched for sex and age, were assessed via the Appendix Life Events of the Minnesota Multiphasic Personality Inventory-Adolescent, the Coping Inventory for Stressful Situations, and the Psychological Well-Being scales. RESULTS: Children living with parents who harmfully consume alcohol had more life events in the 6-month period before the assessment, mostly negative and neutral, and lower levels of psychological well-being than children living with parents who do not harmfully consume alcohol. The risk of having experienced at least one negative or neutral life event was higher in children living with parents who harmfully consume alcohol than in their peers and in those with lower psychological well-being. The risk of having had a positive life event was not related to parents' consumption of alcohol but to avoidant coping and low self acceptance behaviours. CONCLUSIONS: Children living with parents who harmfully consume alcohol need interventions aimed at improving psychological well-being to protect them from life events, especially from negative ones. PMID- 30288841 TI - Macroreentrant atrial tachycardia detouring the epicardium at the anterior wall of the left atrium. AB - A 79-year-old woman with a history of pulmonary vein isolation for persistent atrial fibrillation was admitted for recurrence of atrial tachycardia, with a tachycardia cycle length of 236 milliseconds. The ultra-high-resolution mapping system revealed that tachycardia circuit detouring the epicardium at the anterior wall scar and breaking through to the endocardium below the left atrial appendage. Radiofrequency energy was applied to this site, which successfully terminated the tachycardia. This case suggests that epicardial conduction could occur even at the left atrial anterior wall and identifies a variation in epicardial conduction around the left atrium, which could be a tachycardia circuit. PMID- 30288843 TI - Delayed cord clamping in term large-for-gestational age infants: A prospective randomised study. AB - AIM: To compare the post-natal effects of delayed cord clamping (DCC) and early cord clamping (ECC) in term large-for-gestational age (LGA) infants. METHODS: This prospective randomised study included 51 term LGA infants. The umbilical cords of these infants were clamped at 15 s in group 1 (ECC group (n = 26)) and at 60 s in group 2 (DCC group (n = 25)). Data for Apgar scores, cord blood, pH and lactate values, second haematocrit, 24th bilirubin levels, duration of hospital stay and admission to the neonatal intensive care unit (NICU) were recorded. RESULTS: The demographic characteristics of the infants in the study group were not significantly different. No statistically significant difference was observed in the post-natal haematocrit and bilirubin levels between the groups. Six infants (group 1, n = 3; group 2, n = 3) were diagnosed with polycythaemia (P = 0.79); however, these infants remained asymptomatic, and no treatment was required. One infant in each group developed hyperbilirubinemia, which required phototherapy (P = 1.00). The infant with hyperbilirubinemia in the DCC group presented with asymptomatic polycythaemia. Three neonates in the DCC group required admission to the NICU for transient tachypnoea. CONCLUSIONS: No significant increase in the rate of post-natal complications of DCC in term LGA infants was observed in the study. However, before recommending DCC on a routine basis, studies with a larger sample size and long-term follow-up are required to elucidate the risks and benefits of DCC in this group of infants. PMID- 30288844 TI - The biopsychosocial model of pain in the context of pediatric burn injuries. AB - BACKGROUND: Burns are a common and traumatic source of childhood injury in the United States. The treatment and recovery from burn injuries can be significantly painful and may lead to chronic or persistent pain for years following the initial incident. Further, burn injuries in youth have been found to increase the potential for significant psychosocial (e.g., anxiety, depression, PTSD) and physical (e.g., decreased mobility) impairment. Relatedly, the general experience and processing of pain in youth can also be associated with greater psychosocial (e.g., anxiety, depression) impairment and functional disability over time. However, the phenomenology and associated characteristics of the pain experience following burn injury and, in particular, the potential for combined impact on physical and psychosocial outcomes in youth with severe and/or prolonged pain and a history of burn injury is poorly understood. METHODS: A review of the literature was performed in the areas of burn injuries and outcomes associated with both acute and chronic pain with youth and adult populations. RESULTS: The current review highlights current gaps in the literature in important areas of function in youth with a history of burn injuries using the biopsychosocial model of pain. Future research and considerations for practice are also outlined. CONCLUSIONS: Gaining a greater understanding of the relationship between pain, physical impairment, and psychosocial functioning in these youth is significantly important in order to provide greater preventative and treatment-related intervention going forward. SIGNIFICANCE: Using a biopsychosocial framework, this review highlights the need for a greater understanding of pain processing and the long-term potential for persistent pain and pain-related impairment (e.g., functional disability) in youth with a history of burn injuries. PMID- 30288845 TI - The temporal signature of self: Temporal measures of resting-state EEG predict self-consciousness. AB - The self is the core of our mental life. Previous investigations have demonstrated a strong neural overlap between self-related activity and resting state activity. This suggests that information about self-relatedness is encoded in our brain's spontaneous activity. The exact neuronal mechanisms of such "rest self containment," however, remain unclear. The present EEG study investigated temporal measures of resting state EEG to relate them to self-consciousness. This was obtained with the self-consciousness scale (SCS) which measures Private, Public, and Social dimensions of self. We demonstrate positive correlations between Private self-consciousness and three temporal measures of resting state activity: scale-free activity as indexed by the power-law exponent (PLE), the auto-correlation window (ACW), and modulation index (MI). Specifically, higher PLE, longer ACW, and stronger MI were related to higher degrees of Private self consciousness. Finally, conducting eLORETA for spatial tomography, we found significant correlation of Private self-consciousness with activity in cortical midline structures such as the perigenual anterior cingulate cortex and posterior cingulate cortex. These results were reinforced with a data-driven analysis; a machine learning algorithm accurately predicted an individual as having a "high" or "low" Private self-consciousness score based on these measures of the brain's spatiotemporal structure. In conclusion, our results demonstrate that Private self-consciousness is related to the temporal structure of resting state activity as featured by temporal nestedness (PLE), temporal continuity (ACW), and temporal integration (MI). Our results support the hypothesis that self-related information is temporally contained in the brain's resting state. "Rest-self containment" can thus be featured by a temporal signature. PMID- 30288846 TI - Efficacy and safety of motherwort injection add-on therapy to carboprost tromethamine for prevention of post-partum blood loss: A meta-analysis of randomized controlled trials. AB - Motherwort (YiMuCao), a traditional Chinese herb, has been shown beneficial effects for women's diseases. This meta-analysis aimed to evaluate the efficacy and safety of motherwort injection add-on therapy to carboprost tromethamine for prevention of post-partum blood loss. A systematic literature search was conducted in PubMed, Embase, Cochrane Library, CNKI, VIP and Wanfang from their inception to December 2017. Randomized controlled trials that determined the add on effects of motherwort injection to carboprost for prevention of post-partum blood loss were eligible. Pooled risk ratio (RR) and mean difference (MD) with 95% confidence interval (CI) were used to summarize the effect sizes. Eight trials including 1276 pregnant women fulfilled the inclusion criteria. Prophylactic use of motherwort injection add-on therapy significantly reduced the post-partum 2 h (MD -127.5 mL; 95% CI -149.13 to -105.88) and 24 h (MD -146.85 mL; 95% CI -179.77 to -113.94) blood loss and incidence of post-partum hemorrhage (RR 0.28; 95% CI 0.17-0.45) than carboprost. Moreover, adjunctive treatment with motherwort injection significantly decreased the length of the third stage of labor (MD -3.41 min; 95% CI -4.33 to -2.49) and duration of lochia (MD -7.13 days; 95% CI -8.49 to -5.76). There was no statistical significant difference in the incidence of adverse events (RR 0.76; 95% CI 0.50-1.16). Prophylactic use of motherwort injection add-on therapy to carboprost tromethamine could reduce post partum blood loss. However, more well-designed trials are necessary to confirm the findings of this study due to the methodological flaws of the included trials. PMID- 30288847 TI - Musculoskeletal pain in adults born preterm: Evidence from two birth cohort studies. AB - BACKGROUND: Individuals born preterm are at risk of later developmental problems and long-term morbidities. There is conflicting evidence regarding musculoskeletal pain in young adulthood. We investigated the prevalence of self reported musculoskeletal pain in young adults born across the range of preterm birth compared with a term-born reference group. METHODS: From two Finnish birth cohorts, 184 individuals born early preterm (<34 weeks), 350 late preterm (34 to <37 weeks) and 641 at term completed a self-report questionnaire of musculoskeletal pain at mean age 24.1 (SD: 1.4) years. Group differences were examined by logistic regression models adjusting for sex, age and cohort (Model 1), potential early life confounders (Model 2) and lifestyle factors related to physical (Model 3) and mental health (Model 4). RESULTS: The late preterm group had lower odds for reporting neck pain (0.73; 95% confidence interval (CI): 0.56 0.96), which was further reduced when adjusting for early life confounders and lifestyle factors (Model 4). Odds for reporting peripheral pain were 0.69 (95% CI: 0.48-0.99, Model 4) in the early preterm group. The odds for reporting any pain, shoulder, low back or widespread pain did not differ significantly between groups, although odds for reporting widespread pain were 0.77 (95% CI: 0.58-1.03, Model 4) in the late preterm group. CONCLUSIONS: We did not find evidence of increased prevalence of musculoskeletal pain in adults born early or late preterm. In contrast, our results suggest that adults born preterm have a slightly lower risk of reporting musculoskeletal pain, also when we adjusted for lifestyle factors. SIGNIFICANCE: Young adults born preterm do not have increased rates of musculoskeletal pain. Our findings rather suggest that these rates may be slightly lower than among those born at term. PMID- 30288848 TI - Procedural findings and clinical outcome of second-generation cryoballoon ablation in patients with variant pulmonary vein anatomy. AB - INTRODUCTION: The procedural findings and clinical outcome of second-generation cryoballoon (CB2) ablation in patients with variant pulmonary vein (PV) anatomy have not been fully investigated. METHODS: A total of 424 consecutive patients who underwent PV isolation with CB2 were included. Computed tomographic (CT) scan was performed in all patients before the procedure. The study population was divided into common PV, accessory PV, and nonvariant PV groups according to the CT scan. Procedural findings and clinical outcome between the three groups were compared. RESULTS: Variant PV anatomy was observed in 118 of 424 (27.8%) patients. PV isolation was successfully achieved in all patients in three groups with low rates of need for touch-up ablation (P = 0.974). Total procedure time was longer in the accessory PV group compared with nonvariant PV group (53.7 +/- 12.9 vs 49.5 +/- 8.8 minutes; P < 0.001). More number of applications per patient were required in accessory PV group compared with the nonvariant PV and common PV groups (7.5 +/- 2.1 vs 6.5 +/- 1.6, P < 0.001; 7.5 +/- 2.1 vs 6.8 +/- 1.4, P = 0.027, respectively). No significant difference in phrenic nerve (PN) injury was observed between the three groups (P = 0.693). During mean follow-up duration of 16.1 +/- 3.3 months, there was no significant difference in rates of atrial fibrillation (AF) recurrences in the three groups (13 of 43 common PV group, 21 of 75 accessory PV group, and 80 of 306 nonvariant PV group, P = 0.178). CONCLUSION: Variant PV patterns are common in patients undergoing ablation for drug-resistant AF. CB2 ablation appears to be a reasonable strategy in the setting of the variant PV anatomy with a small increase in procedure time and the number of cryoapplications. PMID- 30288849 TI - Postablation cerebral embolisms in balloon-based atrial fibrillation ablation with periprocedural direct oral anticoagulants: A comparison between cryoballoon and HotBalloon ablation. AB - INTRODUCTION: This prospective observational study aimed to investigate the incidence of symptomatic and silent cerebral embolisms after balloon-based ablation of atrial fibrillation (AF) in patients receiving periprocedural anticoagulation with direct oral anticoagulants (DOACs), and compare that between cryoballoon and HotBalloon ablation (CBA and HBA). METHODS AND RESULTS: We enrolled 123 consecutive AF patients who underwent a balloon-based pulmonary vein isolation (PVI) and brain magnetic resonance (MR) imaging after the ablation procedure (CBA, n = 65; HBA, n = 58). The DOACs were continued in 62 patients throughout the periprocedural period and discontinued in 61 on the procedural day. Intravenous heparin was infused to maintain an activated clotting time of 300 to 400 seconds during the procedure. No symptomatic embolisms occurred in this series. Silent cerebral ischemic lesions (SCILs) were observed on MR imaging in 22 patients (17.9%), and the incidence of SCILs did not significantly differ between the CBA and HBA groups (21.5 vs 13.8%; P = 0.263). According to a multivariate logistic regression analysis, an older age was an independent positive predictor of SCILs (odds ratio, 1.062; 95% CI, 1.001-1.126; P = 0.046), but neither the balloon catheter type nor periprocedural continuation or discontinuation of the DOACs were significant predictors. The incidence of major and minor bleeding complications was comparable between the CBA and HBA groups (1.5 vs 0%, P = 0.528; 7.7 vs 5.2%, P = 0.424). CONCLUSIONS: Both CBA and HBA of AF revealed a similar incidence of postablation cerebral embolisms. Elderly patients may be at a risk of SCILs after a balloon-based PVI with periprocedural DOAC treatment. PMID- 30288850 TI - Sensory disturbances induced by sensorimotor conflicts are higher in complex regional pain syndrome and fibromyalgia compared to arthritis and healthy people, and positively relate to pain intensity. AB - BACKGROUND: Sensorimotor conflicts are well known to induce sensory disturbances. However, explanations as to why patients with chronic pain are more sensitive to sensorimotor conflicts remain elusive. The main objectives of this study were (a) to assess and compare the sensory disturbances induced by sensorimotor conflict in complex regional pain syndrome (n = 38), fibromyalgia (n = 36), arthritis (n = 34) as well as in healthy volunteers (HV) (n = 32); (b) to assess whether these disturbances were related to the intensity and duration of pain, or to other clinical variables assessed using questionnaires (abnormalities in sensory perception, depression and anxiety); and (c) to categorize different subgroups of conflict-induced sensory disturbances. METHODS: One hundred and forty participants performed in phase or anti-phase movements with their arms while viewing a reflection of one arm in a mirror (and the other arm obscured). They were asked to report changes in sensory disturbances using a questionnaire. RESULTS: First, results showed that patients with complex regional pain syndrome and fibromyalgia were more prone to report sensory disturbances than arthritis patients and HV in response to conflicts (small effect size). Second, conflict induced sensory disturbances were correlated with pain intensity (large effect size) and abnormalities in sensory perception (only in the CRPS group) but were not related to the duration of the disease or psychological factors. Finally, we identified two distinct subgroups of conflict-induced sensory disturbances. CONCLUSIONS: Our results suggest that pain lowers the threshold for the detection of sensorimotor conflicts, a phenomenon that could contribute to the maintenance of pain in clinical populations. SIGNIFICANCE: Individuals with complex regional pain syndrome and fibromyalgia were more sensitive to sensorimotor conflicts than arthritis patients and controls. Moreover, conflict-induced sensory disturbances were specific to higher pain intensity and higher sensory abnormalities in all groups, suggesting that pain lowers the threshold for the detection of sensorimotor conflicts. PMID- 30288851 TI - IRGM promotes glioma M2 macrophage polarization through p62/TRAF6/NF-kappaB pathway mediated IL-8 production. AB - Alternatively activated (M2) macrophage promotes glioma progression and immune escape as the most immunocyte in glioma microenvironment. Finding out the key protein regulating M2 macrophage polarization is necessary for improving treatment. Whether immunity related GTPase M (IRGM) is involved in glioma development and M2 macrophage polarization is unknown. IRGM and M2 macrophage marker CD206 expression were examined using immunohistochemistry among 35 glioma and 11 non-cancerous brain specimens. We found IRGM scores were positively correlated with CD206 scores in glioma specimens and monocyte proportion in blood samples. A172 glioma cells transfected with either IRGM knock-down lentivirus (Lenti-IRGM) or control lentivirus (Lenti-HK) were subcutaneously injected into nude mice. In vivo, xenografted glioma size of the Lenti-IRGM group was smaller and had weaker fluorescence signal than Lenti-HK control group. Immunofluorescence results showed that there was obviously decreased IRGM, CD206 and IL-8 expression in the mice glioma of Lenti-IRGM group than Lenti-HK control group. In vitro, flow cytometry results showed that M2 polarization from THP-1 cocultured with Lenti-IRGM glioma cells decreased in contrast to that with Lenti HK glioma cells; there were less interleukin-8 (IL-8) and macrophage inflammation protein 3-alpha (MIP-3alpha), but more interleukin-6 (IL-6) in the supernatant of Lenti-IRGM glioma cells than matched control. Western blot and immunofluorescence displayed that IRGM strongly promoted sequestosome-1 (p62/SQSTM1), necrosis factor receptor-activating factor 6 (TRAF6) expression and NF-kappaB transportation to the nucleus. Realtime PCR results demonstrated IRGM also promoted NF-kappaB downstream cytokines IL-8 and MIP-3alpha mRNA expression. These data suggested that IRGM could promote glioma development and M2 macrophage polarization by regulating p62/TRAF6/NF-kappaB pathway-mediated IL-8 production. PMID- 30288852 TI - Altered tactile localization and spatiotemporal integration in complex regional pain syndrome patients. AB - BACKGROUND: In complex regional pain syndrome (CRPS), altered perception of the affected hand and neglect-like symptoms of the affected body side are common features. In this study, we presented tactile stimuli to the affected hands in CRPS patients and matched healthy controls. METHODS: The participants' task was to point at the perceived positions of the stimuli using a tracking device. The spatial coordinates of the perceived positions were analysed for accuracy and consistency. We also presented patterns consisting of two stimuli at distinct positions with a delay of 100 ms. These patterns are known to induce spatiotemporal integration ("sensory saltation"). RESULTS: CRPS patients were less accurate and less consistent in the spatial perception of tactile stimuli on their hands. Furthermore, they showed increased spatiotemporal integration, although these effects were smaller than expected. These deficiencies were related to the clinically assessed intensity of recurrent pain episodes. Surprisingly, the intensity of clinically assessed ongoing pain was associated with increased precision. CONCLUSIONS: In line with earlier reports, our findings indicate that the representation of the affected hands in CRPS patients is less accurate than in healthy people, probably reflecting reorganization in somatosensory cortices. The exact relationships between these findings and other aspects of CRPS remain to be elucidated. SIGNIFICANCE: CRPS patients performed poorly in localizing positions on their affected hands via pointing and exhibited increased spatiotemporal integration. The presented method may prove useful in diagnostics as well as psychophysical and neurofunctional research on CRPS and other chronic pain disorders. PMID- 30288853 TI - Efficacy and Safety of Computed Tomography-Guided Pulsed Radiofrequency Modulation of Thoracic Dorsal Root Ganglion on Herpes Zoster Neuralgia. AB - OBJECTIVE: Pulsed radiofrequency (PRF) can relieve postherpetic neuralgia (PHN) caused by herpes zoster (HZ) infection. Nevertheless, its curative effect can vary and may be related to the duration of treatment period. The following study investigates the efficacy and safety of CT-guided PRF modulation on HZ neuralgia over different periods and different time points. MATERIALS AND METHODS: A total of 150 patients with HZ/PHN were enrolled at the Pain Department, Shengjing Hospital of China Medical University between January 2013 and December 2016. According to the course of disease, the patients were randomly divided into group A, which included patients with acute stage (n = 50; course <1 m); group B, which included patients with subacute stage (n = 50; 1 m 3 m). The PRF therapy was performed in all patients by targeting thoracic dorsal root ganglion (DRG). The visual analogue scale (VAS), SF-36, total effective rate of treatment, and dosage of antiepileptic analgesic drugs were observed at different time points, before and after the surgery. RESULTS: Compared to preoperative time, decreased VAS, improved SF-36, and the decreased dosage of antiepileptic analgesic drugs were observed at all time points, and in all groups after surgery (p < 0.05). In group A, pain relief lasted longer, and it further decreased over time. In addition, significantly lower VAS, higher SF-36, and lower dosage of antiepileptic analgesic drugs were found in group A compared to group B, and in group B compared to group C (all p < 0.05). Furthermore, the total effective rates in groups A, B, and C were 88, 72, and 52%, respectively. CONCLUSIONS: CT guided PRF targeting thoracic DRG for modulation of HZ neuralgia in different periods is safe and effective. It is recommended to perform early intervention therapy at the acute phase of HZ. PMID- 30288854 TI - Interesting case of dual tachycardia in a patient with surgical closure of atrial septal defect. AB - A 34-year-old gentleman, who had undergone pericardial patch closure of ostium secundum atrial septal defect (ASD) at 8 years of age, was evaluated for shortness of breath. Electrocardiogram revealed typical atrial flutter with varying atrioventricular conduction. Echocardiogram showed no residual ASD or pulmonary hypertension and good biventricular function. He was taken for an electrophysiological study with the intention of radiofrequency ablation of the typical flutter. PMID- 30288855 TI - Mesenchymal stem cells induced anti-inflammatory features in B cells from breast tumor draining lymph nodes. AB - The immune-modulatory effect of adipose-derived stem cells (ASCs) on B cells in cancer has not been well elucidated. Herein, the interaction between B cells and ASCs isolated from the breast fat of either normal (nASCs) or breast cancer women (cASCs) was investigated. B cells derived from breast tumor draining lymph nodes were co-cultured with nASCs or cASCs and B cells proliferation was assessed in direct and transwell assays. Moreover, B cells were co-cultured with cASCs, nASCs or mesenchymal stromal cells of the tumor tissue (TSCs) and B cell cytokine production was assessed using flow cytometery. cASCs or TSCs were co-cultured with either intact or B cell depleted lymphocytes and frequencies of CD25+ FoxP3+ Tregs, IL-10+ or IFN-gamma+ CD4+ T cells were assessed. Results showed that co culture of B cells with ASCs in transwell chambers did not affect B cell proliferation. nASCs, however, was able to significantly reduce B cell proliferation in direct co-culture experiments (P = 0.004). The frequencies of IL 10+ , TNF-alpha+ , IL-2+ , and IFN-gamma+ B cells were not significantly different in the co-cultures of B cells with ASCs or TSCs. But the TNF-alpha+ / IL-10+ B cells ratio decreased in all co-cultures, a reduction merely significant in B cell-cASCs co-culture (P = 0.01). The frequencies of CD4+ T cells subsets in either intact or B cell depleted lymphocytes did not undergo significant changes following co-culture with ASCs or TSCs. Therefore, ASCs is capable of inhibiting B cell proliferation in a contact dependent manner and shifting the cytokine profile of B cells toward an anti-inflammatory profile. PMID- 30288856 TI - Identification of incident pancreatic cancer in Ontario administrative health data: A validation study. AB - PURPOSE: To validate three approaches for identifying incident cases of pancreatic cancer in Ontario administrative claims data. METHODS: We created a cohort using Ontario (Canada) administrative health data from 2002 to 2012 and identified cases of pancreatic cancer with three approaches, using the Ontario Cancer Registry (OCR) as the reference standard. In the any diagnosis approach, cases were defined by primary or secondary diagnostic codes for pancreatic cancer in outpatient or inpatient records. In the any inpatient diagnosis approach, cases were defined using only diagnoses in hospital discharge abstracts. In the algorithm approach, cases were identified by an algorithm that combined the first two approaches. Comparing each approach to the OCR, we calculated the expected value and 95% confidence interval (CI) of the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). We also compared the event dates using each approach with those recorded in the OCR. RESULTS: Among a total of 12 060 837 patients in Ontario administrative health data sources, 13 999 incident pancreatic cancer cases were identified in the OCR. Sensitivity ranged from 72.5% (algorithm) to 97.5% (any diagnosis), and PPV ranged from 38.4% (any diagnosis) to 78.9% (any inpatient diagnosis). Specificity and NPV were ~100% for all approaches. The median absolute difference in cancer event date ranged 0 to 15 days. The any inpatient diagnosis method had the highest PPV (78.9%; 95% CI: 78.2-79.5%) and moderate sensitivity (86.6%; 95% CI: 86.0-87.2%). CONCLUSION: Inpatient diagnoses of pancreatic cancer in Ontario administrative heath data are suitable for pancreatic cancer case identification. PMID- 30288857 TI - Reply to the letter to editor by Zeki Gokhan Surmeli, M.D. PMID- 30288859 TI - Herniation of the amniotic sac through congenital uterine defect confirmed during operation: A case report. AB - Herniation of the amniotic sac into the peritoneal cavity or bladder is a rare but serious condition during pregnancy, which has not been reported in pored congenital uterine anomaly. Here, we report a rare case to draw obstetricians' attention to the atypical uterine rupture. A primigravida at 35 weeks of gestation was admitted for upper abdominal pain. A primary diagnosis of uterine rupture was made after finding the amniotic sac herniation through obstetric ultrasound. Exploration during emergent cesarean section revealed symmetrical pored defect on the uterine horn. The diagnosis of uterine anomaly was eventually made. The educational meaning of this rare case is that it is advisable to rule out uterine anomalies when signs of uterine rupture are suspected during pregnancy while contributory risk factors have not been identified. Besides, it is of vital importance to make a full assessment of both the mother and the fetus so to determine the appropriate time of termination. PMID- 30288858 TI - Preservation of the colo-anal reflex in colonic transection and post-operative Hirschsprung's disease: Potential extrinsic neural pathway. AB - BACKGROUND: The colo-anal reflex is a distinct reflex whereby the internal anal sphincter (IAS) relaxes in association with colonic high amplitude propagating contractions (HAPCs) in contrast to the recto-anal inhibitory reflex (RAIR), which is characterized by IAS relaxation upon rectal distension. The RAIR is mediated by the myenteric plexus and therefore absent in Hirschsprung disease. We retrospectively assessed the presence and the characteristics of the colo-anal reflex in children in whom large bowel continuity had been surgically disrupted to assess the role of the extrinsic nervous system in the reflex. METHODS: High resolution (HR) colonic manometry and HR-anorectal manometry were used to evaluate both colonic and anal motor activity in ten children with treatment unresponsive slow transit constipation (STC), who had previously undergone left sided colostomy formation with consequent disruption of the bowel continuity, and in two children with Hirschsprung's disease (HSCR), who had previously undergone distal colon resection followed by Duhamel pull-through. Eight children with STC, normal colonic motor activity, and preserved large bowel continuity served as a control group. The presence and characteristics of colo-anal reflex were analyzed. KEY RESULTS: In the study group, all patients showed the presence of both normal HAPCs and the presence of the colo-anal reflex. In two cases of HSCR, RAIR was absent; however, both patients demonstrated a colo-anal reflex. CONCLUSIONS: In children with disrupted continuity of the colon and/or abnormal anal reflex, the colo-anal reflex is still preserved suggesting that it is mediated by a different pathway from the RAIR, possibly an extrinsic neural pathway. PMID- 30288860 TI - Loganin prevents BV-2 microglia cells from Abeta1-42 -induced inflammation via regulating TLR4/TRAF6/NF-kappaB axis. AB - Neuroinflammation is closely related with the pathogenesis and progress of neurodegenerative diseases including Alzheimer's disease (AD). Loganin, an iridoid glycoside obtained from traditional Chinese medicine Cornus officinalis, has properties of inhibiting inflammation and improving memory. The present study was aimed to investigate effects of loganin on Abeta-induced inflammation and to explore the underlying mechanisms. BV-2 microglia cells were stimulated with 10 uM Abeta1-42 for 24 h to induce inflammatory damage. According to results of CCK 8 assay, the doses of loganin in present work were 10 and 30 uM. We found that treatment with loganin could inhibit Abeta1-42 -induced microglia activation. Furthermore, loganin treatment prevented the over-production of Tumor necrosis factor-alpha (TNF-alpha), Interleukin-6 (IL-6), Macrophage Chemotactic Protein 1(MCP-1), Nitric oxide (NO), Prostaglandin E2 (PGE2) and the up-regulation of inducible nitric oxide synthase (iNOS) and Cyclooxygenase 2 (COX-2) in Abeta1-42 stimulated BV-2 cells. Results from Western blots demonstrated that loganin inhibited Abeta1-42 -induced elevation in Toll-like receptor 4 (TLR4), Myeloid Differentiation Factor 88 (MyD88) and TNF receptor-associated factor 6 (TRAF6). Loganin treatment also attenuated the increased phosphorylation level of IRAK4 caused by Abeta1-42 . Additionally, loganin alleviated nuclear translocation of NF-kappaB p65 subunit in Abeta1-42 -stimulated BV-2 cells, and this phenomenon could be reversed by TLR4 agonist LPS. Further, the anti-inflammatory effects of loganin were attenuated when TLR4 signaling pathway was re-activated by LPS. Taken together, our data indicated that loganin could attenuate inflammatory response induced by Abeta in BV-2 microglia cells, partially through deactivating the TLR4/TRAF6/NF-kappaB axis. PMID- 30288861 TI - Inpatient disposition in overcrowded hospitals: is it safe and effective to use reverse triage and readmission screening tools for appropriate discharge? An observational prospective study of an Italian II level hospital. AB - BACKGROUND: Reverse triage (RT) identifies patients eligible for discharge and have been proposed to cope with daily surge. Nevertheless, early discharge could increase the rate of readmission. Our aim is to test the effectiveness and safety of RT alone and with readmission screening tools (Identification Senior At Risk [ISAR], HOSPITAL, and Groeningen Frailty Index [GFI] scores) to predict appropriate discharge. MATERIAL AND METHODS: We prospectively assessed every 4 days (t0 ) inpatients of medical divisions (High Dependency Unit (HDU), Internal Medicine (IM), and Geriatrics (Ger)) of an Italian Hospital. RT score was calculated for each patient and an RT <=3 identified those eligible for safe discharge. ISAR, HOSPITAL, and GFI were then applied. We assessed reinstituting of interventions and transferring to an increased level of care unit at 4 days as an ethical proxy of consequential medical events following hypothetical discharge. Date of effective discharge, death, and readmission were measured at 4, 7, 15, and 30 days after the first evaluation. RESULTS: Twenty-five (9.6%) out of 260 patients in our sample had an RT <=3. Twenty-four (96%) of them compared with 205 (87%) of the RT >3 group (P = NS) were discharged. Patients with RT <=3 were discharged significantly earlier (3.5 vs 8 days after t0 [P = 0.0002]). In the RT <=3 group, all but one patient were alive and healthy at 7, 15, and 30 days. The HOSPITAL score seemed to have the best concordance with RT (84%), in comparison with the ISAR (52%) and the GFI (48%) scores. RT showed a low sensitivity (22%) and high specificity (95%), which was even higher when using RT associated with readmission screening tools. CONCLUSIONS: Reverse triage proved to be a safe and conservative tool, with high specificity alone and with readmission screening tools. RT correctly identifies patients that will be discharged earlier. PMID- 30288863 TI - A case report demonstrating potential utility of topical imiquimod for cutaneous Rosai-Dorfman disease.

AB - AIMS: Bacterial microbiome on grape berry surface may play an important role in grape quality and health. This study aims to investigate the impact of grape varieties and clones on grape berry surface bacterial microbiome from the same vineyard. METHODS AND RESULTS: High-throughput sequencing strategy was used to investigate the bacterial diversity and abundance on the grape surfaces of 12 clones belonging to six varieties grown in the same vineyard of Zhengzhou Fruit Research Institute in Henan Province. In total, 45 bacterial phyla and 933 genera were detected from all samples. Cyanobacteria, Proteobacteria and Firmicutes were the most abundant and prevalent phyla, while Bacteroidetes, Chloroflexi, Acidobacteria and Planctomycetes were grape clone specific phyla. The nonrank genus from phylum Cyanobacteria occupied 30-81% of grape clones from Italian Riesling (GRX), Cabernet Franc (PLZ), Pinot Blanc (BBN) and Riesling (LSL). Interestingly, Bacillus, Pseudomonas and Lactococcus were the only three prevalent genera found on all the clones. Furthermore, the predicted functional activities of grape surface bacterial communities varied according to the clones. CONCLUSIONS: The present study revealed that in addition to the grape varieties, the variations in grape clone background may also affect the bacterial microbiome on grape surfaces which may ultimately determine their functional activities. SIGNIFICANCE AND IMPACT OF THE STUDY: This research provides an important information for grape planting and wine fermentation that not only the grape varieties need to be paid attention but also grape clones from the specific variety need to be concerned.

PMID- 30288865 TI - Phylogenetic identificationI of lactic acid bacteria isolates and their effects on the fermentation quality of sweet sorghum (sorghum bicolor) silage. AB - AIM: to isolate, screen and identify the lactic acid bacteria (LAB) from elephant silage during the process of the fermentation and their effects on the fermentation quality of sweet sorghum silage. METHODS AND RESULTS: The isolated strains were identified based on morphological, physiological and biochemical characteristics as well as 16S rRNA analysis. Seven LAB strains were isolated from elephant grass silage. Three strains (Pediococcus acidilactici (AZZ1), Lactobacillus plantarum subsp. Plantarum (AZZ4), Lactobacillus plantarum subsp. Argentoratensis (AZZ7) and one commercial bacteria Lactobacillus Plantarum, Ecosyl MTD/1(CB)) were chosen as additives at 6 log colony forming units (cfu)/g of fresh sweet sorghum grass in laboratory silos (680g). Silos for each treatment were opened after 5, 7, 14, 30 and 60 d, respectively.All isolates were characterized as gram-positive, catalase-negative and grow normally in 6.5% NaCl.The strains AZZ1, AZZ2, and AZZ5, were identified as Pediococcus genus while AZZ3, AZZ4, AZZ6, and AZZ7 were Lactobacillus genus.Compared to the control, all the isolatesimproved the silage quality of sweet sorghum silage, indicated by significantly (P<0.05) lower pH and ammonia nitrogen (NH3 -N) contents and undesirable microorganism counts, and higher lactic acid (LA) contents and ratios of lactic acid/acetic acid (LA/AA). During ensiling, AZZ4 performed better among of all inoculants, indicated by significantly (P<0.05) decreased on pH and ammonia-N contents and higher increased on lactic acid contents. CONCLUSION: strain AZZ4 is recommended as starter culture for sweet sorghum. SIGNIFICANCE AND IMPACT OF THE STUDY: This is the first time to investigate the effects of lactic acid bacteria isolates from elephant grass silage and use them as additives, which is to find out how LAB inoculants improve the fermentation quality of sweet sorghum silage.

AB - OBJECTIVES: The primary objective of this study was to explore the impact of noninvasive Vagal Nerve Stimulation (nVNS) on brain electrophysiology, as assessed through spontaneous resting-state EEG and stimulus-driven event-related potentials (ERPs). METHODS: A hand-held transcutaneous stimulator was placed on the neck over the main branch of the left vagus (active condition) or more laterally over neck muscles (sham condition), with two 120-sec long bursts of stimulation applied over a five-minute period. For each of eight neurotypical subjects, prior to stimulation, and then again beginning at 15, 120, and 240 min post-stimulation, ten minutes of background EEG data were collected, along with a series of ERPs-N100 auditory sensory-gating; the N1/P2 loudness dependent auditory evoked responses (LDAER); mismatch negativity; P300a; and P300b. Each subject participated in active and sham stimulation sessions. RESULTS: Brief nVNS had a significant (p < 0.05), and in some cases prolonged (>2 hours), impact on the spontaneous EEG (decreased theta and alpha, and increased beta and gamma), and on sensory gating, LDAER, and P300b evoked responses. Based on prior literature, these specific observations may reflect nVNS-induced modulation of particular neurotransmitter systems including those for GABA (gamma power and frequency); acetylcholine (sensory gating); serotonin (LDAER); and noradrenaline (P300b). CONCLUSIONS: Brief nVNS leads to changes in a sub-set of resting-state and event-related electrophysiologic indices of brain activity. These changes are believed to be mediated by vagal afferent projections to the nucleus of the solitary tract, which in turn regulates several neurotransmitter systems through known direct and indirect neuroanatomic pathways. PMID- 30288868 TI - Mexican-American adolescents' perceptions about causes of perinatal depression, self-help strategies, and how to obtain mental health information. AB - PROBLEM: Perinatal depression is a public health concern as it is associated with adverse pregnancy outcomes. Previous studies have recommended further examination of perinatal depression among Mexican-American adolescents. Thus, the purpose of this study was to understand pregnant and postpartum Mexican-American adolescents' knowledge and beliefs concerning perinatal depression. METHODS: This qualitative descriptive study examined perceptions about the causes of perinatal depression, self-help strategies, and how to obtain mental health information. Data were analyzed using deductive and inductive qualitative content analysis. A convenience sample, consisiting of 20 pregnant and postpartum adolescents, self identified as Mexican-Americans, between the ages of 15 and 19 years was interviewed. FINDINGS: The quality of relationships with their family and significant other and difficulties in transitioning to motherhood were described as potential causes for depression. Journaling, exercising, and spending time with friends and family were identified as self-help strategies. Healthcare providers, the internet, and mothers who have experienced depression were stated as helpful sources of mental health information. CONCLUSION: An assessment of their psychosocial environment is indicated to identify risk or protective factors for perinatal depression. Its consideration and inclusion in interventions may optimize mental health among perinatal adolescents.

PMID- 30288867 TI - Recombinant human follicle stimulating hormone purification by a short peptide affinity chromatography. AB - Peptide KVPLITVSKAK was selected to design a synthetic ligand for affinity chromatography purification of recombinant human follicle stimulating hormone (rhFSH), based on the interaction of the hormone with the exoloop 3 of its receptor. The peptide was acetylated to improve its stability to degradation by exopeptidases. A cysteine was incorporated at the C-termini to facilitate its immobilization to the chromatographic activated SulfoLink agarose resin. A sample of crude rhFSH was loaded to the affinity column, using 20 mM sodium phosphate, 0.5 mM methionine, and pH 5.6 and 7.2 as adsorption and elution buffers, respectively. The dynamic capacity of the matrix was 54.6 mg rhFSH/mL matrix and the purity 94%. The percentage of oxidized rhFSH was 3.4%, and that of the free subunits was 1.2%, both in the range established by the European Pharmacopeia, as also were the sialic acid content and the isoforms profile. PMID- 30288870 TI - Characterization of a peptide containing the major heparin binding domain of human hepatic lipase. AB - Human hepatic lipase (hHL) is a cell surface associated enzyme that hydrolyzes triacylglycerols and phospholipids within circulating lipoproteins. We hypothesized that an amino acid sequence mimicking the major heparin binding domain (HBD) of hHL will displace hHL from cell surfaces. To test this hypothesis, we generated a recombinant protein of thioredoxin linked with a cleavable, tagged sequence containing amino acids 442 to 476 of the mature hHL sequence, which contains the major HBD of hHL. The recombinant protein associated with heparin-sepharose, and its peak elution from heparin-sepharose occurred in the presence of 0.5 M NaCl. We cleaved and purified the tagged sequence containing the HBD from the recombinant protein and tested the ability of the peptide to displace full-length hHL from HEK-293 cells. The peptide indeed displaced hHL from cell surfaces, while no significant displacement was observed in the presence of a peptide with a scrambled sequence. Finally, we obtained structural information for the peptide containing the HBD. 1 H- and 15 N-NMR spectra of the peptide indicate the peptide is largely unstructured, although not completely random coil. The addition of heparin to the peptide induced some changes in chemical shift, suggesting changes in peptide structure and/or specific interactions with heparin. Molecular simulations confirm the largely unstructured nature of the isolated peptide, but they also indicate weak tendencies for both alpha- and beta-structure formation in different parts of the chain. Overall, these data provide a proof-of-principle for the use of mimetic peptides for the displacement of cell surface associated lipases. PMID- 30288871 TI - Paradox of meritocracy in surgical selection, and of variation in the attractiveness of individual specialties: to what extent are women still disadvantaged? AB - BACKGROUND: Evidence from outside surgery suggests that meritocracy-based processes around selection tend to reduce, rather than increase, diversity. In recent years, the surgical training boards have gone to considerable effort to achieve greater transparency and fairness in their selection processes, and to identify those attributes that are believed to best predict future success as a surgeon. This is consistent with the Royal Australasian College of Surgeons Diversity and Inclusion Plan, which places emphasis on gender equity and has goals that include increasing the attractiveness of surgery as a vocation for women, removing impediments to them applying to the surgical training programmes and removing any biases that might disadvantage them during the selection process. METHODS: This study uses the Female Opportunity Index and rate ratio metrics to measure the level of female disadvantage in surgical selection, whether it be by the perception of its attractiveness to women which influences their application rates, or by the likelihood of successful selection for those who have applied, compared with their male counterparts. RESULTS: There are marked differences between the nine surgical specialties and 13 specialty training boards in both the proportion of women who apply, and the proportion who are successful in gaining entry onto the Surgical Education and Training programmes. The Female Opportunity Index ranged from 0.21 to 0.87, which represents a wide variation between surgical specialties. CONCLUSION: These data raise the question as to whether unconscious bias is occurring in an apparently meritocracy-based selection process in some specialties. The data also suggest that some specialties are relatively unattractive to women, for which the reasons are likely to be complex. PMID- 30288872 TI - Secondary failure of TNF-alpha inhibitors in clinical practice. AB - Tumor necrosis factor alpha (TNF-alpha) is a leading inflammatory cytokine that plays a pivotal role in the pathogenesis of psoriasis. In case of a severe course of psoriasis and moderate-to-severe disease in which traditional systemic treatments are ineffective or contraindicated, TNF-alpha inhibitors (iTNF-alpha) are used. This class of drugs includes monoclonal antibodies and a fusion protein (etanercept) and can induce a humoral or cell-mediated immune response, leading to formation of anti-drug antibodies (ADAs). The immunogenicity may affect iTNF alpha drug pharmacokinetics, which would lead to hampering the clinical response (secondary drug failure), so a need to increase the drug dose arises. Antibodies against monoclonal antibodies (adalimumab, infliximab) have been associated with diminished clinical response, while against etanercept are non-neutralizing and appear to have no significant effect on clinical response and treatment safety. Switching of biologic agents may be one strategy in ADA-associated secondary failure of iTNF-alpha. However researches are needed to identify risk factors for ADA development and investigate management strategies for optimized treatment response. The authors reviewed the literature on the effectiveness of iTNF-alpha and pointed out the prevention of secondary failure in clinical practice. PMID- 30288873 TI - Transabdominal selective feticide in dichorionic twins: Ten years' experience at a single center. AB - AIM: The present study investigates the procedure-related fetal loss rate and obstetrical outcomes of selective feticide in dichorionic twins. METHODS: We retrospectively analyzed the data of 44 cases of dichorionic twins. Two different indications for selective feticide were set: (i) the presence of genetic or congenital anomaly; and (ii) an obstetrical indication specified as a past maternal history of preterm delivery that caused fetal death or cerebral palsy of the child. Primarily, data on procedure-related fetal loss and obstetrical outcomes were retrieved. Additionally, data on obstetrical outcomes by reduction time and by indication of SF were obtained. RESULTS: Selective feticide was performed in 44 cases - specifically, in 23 cases with genetic or congenital anomaly and in 21 cases with obstetrical indications. The median gestational age at delivery was 38 + 4 weeks. One pregnancy loss (2.3%, 1/44) occurred within 4 weeks after the procedure. The overall pregnancy loss rate throughout the pregnancy term was 2.3% (1/44). When selective feticide was performed at 15 weeks and beyond, the birth weight was significantly decreased compared with when selective feticide was performed earlier than 15 weeks. CONCLUSION: Transabdominal ultrasound-guided selective feticide in dichorionic twins is an effective and safe procedure. If a patient desires to maximize her chances of having a healthy child and decrease the risk of prematurity, the option of selective feticide should be considered in certain cases of twin pregnancies. Selective feticide may be a reasonable alternative to expectant management or termination of the whole twin pregnancy.

PMID- 30288875 TI - Implication of SLIT3-ROBO1/ROBO2 in granulosa cell proliferation, differentiation and follicle selection in the prehierarchical follicles of hen ovary. AB - The SLIT/ROBO pathway has been implicated in prehierarchical follicular development of hen ovary by an intrafollicular autocrine and/or paracrine fashion. SLIT3, one of the key components of the SLIT/ROBO family, serves as a ligand that potentially interacts with the four receptors, ROBO1, ROBO2, ROBO3 and ROBO4. But the exact roles and regulatory mechanism of SLIT3 in chicken ovarian follicle development remain largely unclear. The present study was conducted to investigate the potential roles and molecular regulation of SLIT3 in granulosa cell (GC) proliferation, differentiation and follicle selection within the prehierarchical follicles of hen ovary. We found that SLIT3 interacts physically with the four ROBO receptors, but the expression of the ROBO1 and ROBO2 genes are more susceptible to the regulation of SLIT3 ligand than that of the ROBO3 and ROBO4 genes. Moreover, the siRNA-mediated knockdown of SLIT3 in the follicular GCs leads to a significant increase in cell proliferation. Conversely, overexpression of SLIT3 results in a remarkable reduction in GC proliferation. Furthermore, the overexpressed SLIT3 has notably decreased the mRNA and protein expression levels of follicle-stimulating hormone (FSHR), growth and differentiation factor 9 (GDF9), steroidogenic acute regulatory protein (STAR) and cytochrome P450 11A1 (CYP11A1) in the GCs. These results indicated that SLIT3 may play an inhibitory effect on GC proliferation, differentiation and follicle selection, and these suppressive actions of SLIT3 in the GC proliferation can be prohibited by the siRNA-mediated knockdown of ROBO1 and ROBO2 receptors. The current data provide a basis for further investigation of molecular mechanisms of SLIT3-ROBO1/2 pathway in controlling the prehierarchical follicle development of the hen ovary. PMID- 30288876 TI - Experimentally manipulating light spectra reveals the importance of dark corridors for commuting bats. AB - The rapid global spread of artificial light at night is causing unprecedented disruption to ecosystems. In otherwise dark environments, street lights restrict the use of major flight routes by some bats, including the threatened lesser horseshoe bat Rhinolophus hipposideros, and may disrupt foraging. Using radio tracking, we examined the response of individual female R. hipposideros to experimental street lights placed on hedgerows used as major flight routes. Hedgerows were illuminated on one side over four nights using lights with different emission spectra, while the opposite side of the hedge was not illuminated. Automated bat detectors were used to examine changes in overall bat activity by R. hipposideros and other bat species present. R. hipposideros activity reduced significantly under all light types, including red light, challenging a previously held assumption that red light is safe for bats. Despite this, R. hipposideros rapidly adapted to the presence of lights by switching their flight paths to the dark side of the hedgerow, enabling them to reach foraging sites without restriction. Red light had no effect on the activity of the other species present. Slow-flying Myotis spp. avoided orange, white and green light, while more agile Pipistrellus spp. were significantly more active at these light types compared to dark controls, most probably in response to accumulations of insect prey. No effect of any light type was found for Nyctalus or Eptesicus spp. Our findings demonstrate that caution must be used when promoting forms of lighting that are thought to be safe for wildlife before they are tested more widely. We argue that it is essential to preserve dark corridors to mitigate the impacts of artificial light at night on bat activity and movements.

AB - Gaining control over supramolecular polymerization mechanisms is of high fundamental interest to understand self-assembly and self-organization processes at the nanoscale. It is also expected to significantly impact the design and improve the efficiency of advanced materials and devices. Up to now, supramolecular polymerization has been shown to take place from unimers in solution, mainly by variations of temperature or of concentration. Reported here is that supramolecular nucleation-growth of triarylamine monomers can be triggered by electrochemistry in various solvents. The involved mechanism offers new opportunities to precisely address in space and time the nucleation of supramolecular polymers at an electrode. To illustrate the potential of this methodology, supramolecular nanowires are grown an oriented over several tens of micrometers between different types of commercially available electrodes submitted to a single DC electric field, reaching a precision unprecedented in the literature. PMID- 30288879 TI - A DNA priming and protein boosting immunization scheme to augment immune responses against parvovirus in ducks. AB - AIMS: To evaluate the effect of a DNA priming and protein boosting immunization scheme in ducks. METHODS AND RESULTS: Pekin ducks were immunized with pTCY/VP2 DNA vaccine; on day 14 (D14) after primary immunization, the ducks were boosted with either the same vaccine (DNA + DNA) or the rVP2 vaccine (DNA + rVP2). CpG oligodeoxynucleotides containing three copies of GACGTT motifs were used as the adjuvant in the vaccines. Compared with unimmunized controls, both immunization schemes significantly increased the titre of antigen-specific antibodies, lymphocyte proliferation index, percentage of CD4+ and CD8+ cells in peripheral blood mononuclear cells (PBMCs) and mRNA expression of interferon (IFN)-alpha, IFN-gamma, interleukin (IL)-6 and IL-12 in antigen-stimulated PBMCs. Furthermore, compared with the DNA + DNA homologous scheme, the DNA + rVP2 heterologous scheme significantly increased lymphocyte proliferation, percentage of CD4+ and CD8+ cells in PBMCs and upregulation of mRNA expression of cytokines 2 weeks after the boost (D28). CONCLUSIONS: The DNA + rVP2 immunization scheme enhanced immune responses, mainly Th1 type, against parvovirus in ducks. SIGNIFICANCE AND IMPACT OF THE STUDY: The DNA priming and protein boosting heterologous immunization strategy can be applied to develop vaccines against viral infections in ducks. It can potentially be used in breeding ducks because of long-term immunity may confer protection for ducklings. PMID- 30288880 TI - Ocular abnormalities in a herd of Old Kladruber Horses: A cross-sectional study. AB - OBJECTIVE: To screen a closed herd of the Old Kladruber Horses (OKH) for the prevalence of ocular disorders and report normal ocular variations. ANIMALS STUDIED: Two hundred and sixty-one horses, 122 Old Kladruber Gray Horses, and 139 Old Kladruber Black Horses owned by the National Stud Farm Kladruby nad Labem, Czech Republic, were included in the study with signalment and pedigree information recorded. PROCEDURES: Bilateral ocular examination of manually restrained horses was performed in a darkened environment by a single examiner (RA), using a portable slit-lamp biomicroscope, direct ophthalmoscope, and monocular indirect ophthalmoscopy using a Finnoff transilluminator and 20 D condensing lens. Fluorescein testing was performed when indicated. RESULTS: The animal ages ranged from 3 months to 27 years (mean 7.82 years, median 6 years). The gender ratio (males:females) was 109:152. Ophthalmological abnormalities were found in 133 (50.96%) horses; with right and left eyes affected equally. The most common abnormalities were cataract formation (35 horses), iris hyperpigmentation (29 horses), alterations in corpora nigra size (26 horses), nonsenile vitreal degeneration (24 horses), linear keratopathy (11 horses), corneal stromal haze (nine horses) and corneal subepithelial punctate opacities (nine horses). The most frequent variations of normal ocular anatomy were posterior lenticular suture lines (222 horses), tapetal hypoplasia (95 horses) resulting in a multi colored tapetal fundus (31 horses), nuclear sclerosis (48 horses), and senile vitreal degeneration (30 horses). CONCLUSIONS: Ocular disorders were relatively common in OKH, but typically not vision threatening and not interfering with the quality of life. PMID- 30288881 TI - Intralesional 2% zinc sulfate solution for plane warts: A case report. AB - Warts are benign epithelial proliferations of the skin and mucous membranes caused by human papilloma viruses (HPVs). Plane warts are mainly caused by HPV-3 and HPV-10. There is no absolute effective single treatment, and multiple treatment modalities may be combined. One must take into consideration the probability of spontaneous regression, and so the therapeutic approach should not be too aggressive. We report a case of 11 years immunocompetent child presenting with recalcitrant multiple plane warts who was successfully treated with intralesional 2% zinc sulfate solution injection in one lesion after a failure of many other treatment modalities. Our case may represent a starting point for further studies to evaluate the best dose used for management and to avoid any side effects. Intralesional zinc sulfate injection could be a promising treatment option for plane warts.

PMID- 30288884 TI - Evaluation of axitinib to downstage cT2a renal tumours and allow partial nephrectomy: a phase II study. AB - OBJECTIVE: To evaluate the ability of neoadjuvant axitinib to reduce the size of T2 renal cell carcinoma (RCC) for shifting from a radical nephrectomy (RN) to a partial nephrectomy (PN) indication, offering preservation of renal function. PATIENTS AND METHODS: Patients with cT2aN0NxM0 clear-cell RCC, considered not suitable for PN, were enrolled in a prospective, multicentre, phase II trial (AXIPAN). Axitinib 5 mg, and up to 7-10 mg, was administered twice daily, for 2-6 months before surgery, depending on the radiological response. The primary outcome was the number of patients receiving PN for a tumour <7 cm in size after neoadjuvant axitinib. RESULTS: Eighteen patients were enrolled. The median (range) tumour size and RENAL nephrometry score were 76.5 (70-98) mm and 11 (7 11), respectively. After axitinib neoadjuvant treatment, 16 tumours decreased in diameter, with a median size reduction of 17% (64.0 vs 76.5 mm; P < 0.001). The primary outcome was considered achieved in 12 patients who underwent PN for tumours <7 cm. Sixteen patients underwent PN. Axitinib was tolerated in the present study, as has been previously shown in the metastatic setting. Five patients had grade 3 adverse events. Five patients experienced Clavien III-V post surgery complications. At 2-year follow-up, six patients had metastatic progression, and two had a recurrence. CONCLUSION: Neoadjuvant axitinib in cT2 ccRCC is feasible and, even with a modest decrease in size, allowed a tumour shrinkage <7 cm in 12 cases; however, PN procedures remained complex, requiring surgical expertise with possible morbidity. PMID- 30288886 TI - Rapid, Quantitative, and Ultrasensitive Point-of-Care Testing: A Portable SERS Reader for Lateral Flow Assays in Clinical Chemistry. AB - The design of a portable Raman/SERS-LFA reader with line illumination using a custom-made fiber optic probe for rapid, quantitative, and ultrasensitive point of-care testing (POCT) is presented. The pregnancy hormone human chorionic gonadotropin (hCG) is detectable in clinical samples within only 2-5 s down to approximately 1.6 mIU mL-1 . This acquisition time is several orders of magnitude shorter than those of existing approaches requiring expensive Raman instrumentation, and the method is 15-times more sensitive than a commercially available lateral flow assay (LFA) as the gold standard. The SERS-LFA technology paves the way for affordable, quantitative, and ultrasensitive POCT with multiplexing potential in real-world applications, ranging from clinical chemistry to food and environmental analysis as well as drug and biowarfare agent testing. PMID- 30288885 TI - Relationship between the Functional Independence Measure and Mann Assessment of Swallowing Ability in hospitalized patients with pneumonia. AB - AIM: Pneumonia ranks high among the causes of death worldwide. However, the predictive values of activities of daily living, the nutrition index and the aspiration index measured objectively remain unclear. The present study aimed to examine the associations of activity, nutrition and dysphagia with pneumonia. METHODS: We assessed 992 hospitalized patients. Logistic regression analysis was used to examine the predictors of pneumonia. Receiver operating characteristic curve analysis was used to determine the cut-off values of variables. Kaplan Meier and Cox hazards regression analyses were used to examine the incidence of pneumonia and the factors associated with pneumonia. RESULTS: We finally enrolled 393 inpatients. Of the 393 patients, 102 (26.0%) had pneumonia. On logistic regression analysis, age, Functional Independence Measure (FIM)-motor score and Mann Assessment of Swallowing Ability (MASA) score were independent predictors of pneumonia. The FIM-motor and MASA cut-off values were 19.5 (area under the curve 0.83, P < 0.01) and 170.5 (area under the curve 0.82, P < 0.01), respectively. Kaplan-Meier analysis showed that the no pneumonia rate was significantly lower among patients with FIM-motor scores <20 than among those with FIM-motor scores >=20 (log-rank test, P < 0.01), and was significantly lower among patients with MASA scores <171 than among those with MASA scores >=171 (log-rank test, P < 0.01). Cox regression analysis showed that FIM-motor (hazard ratio 0.97, P = 0.009) and MASA scores (hazard ratio 0.99, P < 0.01) were significantly associated with pneumonia. CONCLUSIONS: In addition to the infectious risk, the FIM-motor and MASA scales are useful tools to predict the development of pneumonia in older adults. Geriatr Gerontol Int 2018; **: **-**. PMID- 30288887 TI - A Tailored DNA Nanoplatform for Synergistic RNAi-/Chemotherapy of Multidrug Resistant Tumors. AB - Multidrug resistance (MDR) is a major obstacle in the clinical treatment of cancer. Herein, a facile strategy is reported to construct a versatile DNA nanostructure as a co-delivery vector of RNA interference (RNAi) and chemodrugs to combat multidrug-resistant tumor (MCF-7R) in vitro and in vivo. In the tailored nanocarrier, two linear small hairpin RNA (shRNA) transcription templates targeting MDR-associated genes (gene of P-glycoprotein, a typical drug efflux pump; and gene of survivin, a representative anti-apoptotic protein) are precisely organized in the chemodrug (doxorubicin, DOX) pre-loaded DNA origami. With the incorporation of active targeting and controlled-release elements, these multifunctional DNA nanocarriers can successfully enter the target MCF-7R cells and synergistically inhibit tumor growth without apparent systemic toxicity. This tailored DNA nanoplatform, which combines RNAi therapy and chemotherapy, provides a new strategy for the treatment of multidrug-resistant tumors.

SUMMARY: Background The complex, interdependent contact activation system has been implicated in thrombotic disease, although few genetic determinants of levels of proteins from this system are known. Objectives Our primary aim was to study the influence of common F11, F12, KLKB1, and KNG1 variants on factor (F) XI activity and FXI, FXII, prekallikrein (PK) and high-molecular-weight kininogen (HMWK) antigen levels, as well as the risk of myocardial infarction and ischemic stroke. Patients/methods We analyzed samples from all 630 healthy participants, 182 ischemic stroke patients and 216 myocardial infarction patients in the RATIO case-control study of women aged < 50 years. Forty-three tagging single nucleotide variants (SNVs) were genotyped to represent common genetic variation in the contact system genes. Antigen and activity levels were measured with sandwich-ELISA-based and one-stage clotting assays. We performed single variant, age-adjusted, linear regression analyses per trait and disease phenotype, assuming additive inheritance and determined conditionally independent associations. Haplotypes based on the lead SNV and all conditionally independent SNVs were tested for association with traits and disease. Results We identified two novel associations of KLKB1 SNV rs4253243 with PK antigen (betaconditional = 12.38; 95% CI, -20.07 to -4.69) and KNG1 SNV rs5029980 with HMWK antigen (betaconditional = 5.86; 95% CI, 2.40-9.32) and replicated previously reported associations in a single study. Further analyses probed whether the observed associations were indicative of linkage, pleiotropic effects or mediation. No individual SNVs or haplotypes were associated with the disease outcomes. Conclusion This study adds to current knowledge of how genetic variation influences contact system protein levels and clarifies interdependencies.

AB - Despite substantial progress made towards a better understanding of the importance of skeletal muscle K+ regulation for human physical function and its association with several disease states (eg type-II diabetes and hypertension), the molecular basis underpinning adaptations in K+ regulation to various stimuli, including exercise training, remains inadequately explored in humans. In this review, the molecular mechanisms essential for enhancing skeletal muscle K+ regulation and its key determinants, including Na+ ,K+ -ATPase function and expression, by exercise training are examined. Special attention is paid to the following molecular stressors and signaling proteins: oxygenation, redox balance, hypoxia, reactive oxygen species, antioxidant function, Na+ ,K+ , and Ca2+ concentrations, anaerobic ATP turnover, AMPK, lactate, and mRNA expression. On this basis, an update on the effects of different types of exercise training on K+ regulation in humans is provided, focusing on recent discoveries about the muscle fibre-type-dependent regulation of Na+ ,K+ -ATPase-isoform expression. Furthermore, with special emphasis on blood-flow-restricted exercise as an exemplary model to modulate the key molecular mechanisms identified, it is discussed how training interventions may be designed to maximize improvements in K+ regulation in humans. The novel insights gained from this review may help us to better understand how exercise training and other strategies, such as pharmacological interventions, may be best designed to enhance K+ regulation and thus the physical function in humans.

AB - BACKGROUND: Several unanswered questions surround the management of retroperitoneal sarcoma (RPS). Guidelines recommend treatment by a multidisciplinary team at a specialized referral centre. The objective of this study was to describe the management of RPS at an Australian specialist sarcoma centre, comparing outcomes to international standards and analysing for predictors of local failure. METHODS: A retrospective review of a prospectively maintained database was performed on patients with RPS treated between 2008 and 2016. A 5-year outcome analyses focussed on patients undergoing curative-intent surgery for primary, non-metastatic RPS. RESULTS: Eighty-eight patients underwent surgery for primary RPS. Five-year overall survival was 66%, 5-year freedom from local recurrence was 65% and 5-year freedom from distant metastasis was 71%. Overall survival was associated with tumour grade (hazard ratio (HR) 6.1, P < 0.001) and histologic organ invasion (HR 5.7, P < 0.001). Variables associated with improved freedom from local recurrence were macroscopically complete resection (HR 0.14, P < 0.001) and neoadjuvant radiotherapy (HR 0.33, P = 0.014). Treatment at a specialist sarcoma centre was associated with a higher rate of preoperative biopsy and neoadjuvant radiotherapy (both with P < 0.001). There was a trend towards improved local control for patients undergoing surgery at a specialist centre (P = 0.055). CONCLUSION: This is the largest Australian series of RPS and outcomes are comparable to major international sarcoma centres. Patients treated at a specialist centre had higher rates of preoperative diagnosis and tailored therapy which was associated with improved outcomes. Patients with suspected RPS should be referred to a specialist centre for optimal preoperative evaluation and multidisciplinary management. PMID- 30288893 TI - Update on diagnosis and anticoagulant therapy for venous thromboembolism. AB - Venous thromboembolism (VTE) continues to be a common medical problem requiring the need for rapid treatment with anticoagulant therapy. Until the recent availability of the direct oral anticoagulants for treatment of VTE, the option for oral anticoagulation was limited to warfarin therapy. The addition of these new medications has been welcomed, but has led to added complexities in deciding the most appropriate agent for each patient based on individual risk factors. Furthermore, there are several circumstances where optimal duration of therapy is not well established. This article will focus on the diagnosis of VTE, the choice of anticoagulant and treatment duration. PMID- 30288894 TI - No live vaccines for people being treated with leflunomide.

PMID- 30288895 TI - Supporting the on-call primary care physician with community paramedicine. AB - Prior to being referred to the emergency department (ED), patients such as the frail elderly often call their primary care physician. However, the on-call primary care physician or covering provider does not always have the tools to make an accurate and safe assessment over the phone or to treat patients remotely. This often results in preventable transport to an ED, avoidable admissions and iatrogenic events. An opportunity exists to reduce unnecessary ED referrals by enhancing the capabilities of the on-call primary care physician. In this communication, we describe the development of a community paramedicine programme that supports on-call primary care providers managing a high-risk patient population with the goal of reducing avoidable ED referrals.

AB - Hereditary haemorrhagic telangiectasia is characterised by abnormal blood vessel formation, producing telangiectasia and arteriovenous malformations in multiple organs. Information regarding possible renal involvement in hereditary haemorrhagic telangiectasia is limited. This study assessed renal structure and function in 11 patients with genetically confirmed diagnosis and known arteriovenous malformations in lung, liver, gastrointestinal tract or brain. All had significant current or past epistaxis. Despite the vascularity of the kidneys, we found no evidence of renal involvement. This observation warrants further consideration.

AB - Decompressive hemicraniectomy (DHC) has been shown to reduce mortality in malignant middle cerebral artery (MCA) infarction. Our primary objective was to compare 1-year mortality between patients receiving DHC for malignant MCA infarction at our institution based on hospital of origin. We retrospectively reviewed the medical records of all patients treated for malignant MCA infarction with DHC at our institution over a 3-year period. One-year mortality rates and time to surgery were comparable regardless of whether the patient first attended the tertiary referral centre or a peripheral centre.

AB - Incidental findings, including pulmonary nodules, on computed tomography coronary angiography (CTCA) are common. Previous authors have suggested CTCA could allow opportunistic screening for lung cancer, though the lung cancer risk profile of this patient group has not previously been established. Smoking histories of 229 patients undergoing CTCA at two tertiary hospitals were reviewed and only 25% were current or former smokers aged 55-80 years old. Less than half of this group were eligible for screening based on the PLCOm2012 risk model. We conclude that routine screening in the form of full thoracic field imaging, of individuals undergoing CTCA is not appropriate as it would likely result in net harm. PMID- 30288903 TI - Changing landscape of hereditary breast and ovarian cancer germline genetic testing in Australia. AB - Federal funding for germline genetic testing in hereditary breast and ovarian cancer (HBOC) was recently introduced. Germline testing for HBOC under Medicare Benefits Schedule items 73296/73297 can be requested by any specialist, whereas the previous state- and territory-funded testing was limited to those operating within a familial cancer service. The impact of this decentralisation of HBOC testing on health and economic outcomes is uncertain, primarily as it has potential to significantly disrupt the clinical framework that generated the evidence used to justify clinical implementation of the Medicare Benefits Schedules. PMID- 30288904 TI - Never too old for an inherited condition. AB - Primary ciliary dyskinesia is an uncommon, inherited condition causing progressive suppurative airway lung disease with subsequent bronchiectasis, chronic rhinitis-sinusitis, deafness and reduced fertility. Diagnosis is often delayed by lack of awareness of the condition in the medical community and limited access to the few centres in Australia able to do full diagnostic testing. This report details the late diagnosis of primary ciliary dyskinesia in two adults who have had long-standing interactions with medical services but in whom the diagnosis was never considered or even dismissed. Greater awareness of the condition will reduce time to diagnosis, prevent administration of ineffective therapy and allow earlier institution of targeted therapy. PMID- 30288905 TI - Author reply.

AB - OBJECTIVE: The aim of the study was to determine the lacrimal fluid (LF) contents of glucose, urea nitrogen, and creatinine in cats. ANIMAL STUDIED: A total of 96 cats were included in the study. PROCEDURE: Venous blood and LF samples were collected. For LF sampling, three small polyurethane sponges were placed in the ventral fornix of both eyes. Both LF and plasma concentrations of glucose, urea nitrogen, and creatinine were quantitatively analyzed and compared. RESULT: Glucose (n = 40) and urea nitrogen concentrations (n = 42) measured in LF from both eyes highly correlated. While there was a very strong correlation (rho = 0.97) between urea nitrogen concentrations in blood plasma and the corresponding tear levels (with the median LF urea nitrogen being 109% of that measured in plasma), the LF glucose concentrations were significantly lower than the corresponding plasma concentrations (with only 13% of the blood glucose concentration detected in the LF). The creatinine concentrations in tears were much lower than those in plasma, and LF creatinine was detectable in only 12/48 cats (25%). Hence, a comparison of the LF creatinine concentrations between both eyes or with the corresponding plasma creatinine concentration was not possible. CONCLUSION: Measurement of LF urea nitrogen concentrations in cats appears to be reliable and might have potential clinical utility. Measurement of LF glucose concentrations is less reliable but may still be useful in some cats. Creatinine is not reliably detected in the LF in cats. Further studies determining clinical utility of LF metabolites in cats and other companion animals are warranted. PMID- 30288907 TI - Discovery of an MLLT1/3 YEATS Domain Chemical Probe. AB - YEATS domain (YD) containing proteins are an emerging class of epigenetic targets in drug discovery. Dysregulation of these modified lysine-binding proteins has been linked to the onset and progression of cancers. We herein report the discovery and characterisation of the first small-molecule chemical probe, SGC iMLLT, for the YD of MLLT1 (ENL/YEATS1) and MLLT3 (AF9/YEATS3). SGC-iMLLT is a potent and selective inhibitor of MLLT1/3-histone interactions. Excellent selectivity over other human YD proteins (YEATS2/4) and bromodomains was observed. Furthermore, our probe displays cellular target engagement of MLLT1 and MLLT3. The first small-molecule X-ray co-crystal structures with the MLLT1 YD are also reported. This first-in-class probe molecule can be used to understand MLLT1/3-associated biology and the therapeutic potential of small-molecule YD inhibitors. PMID- 30288909 TI - Improving the accuracy of the initial rise method and extending its applicability to evaluate the order of kinetics of TL glow peaks. AB - The classical initial rise method is limited to evaluate the activation energy for signal levels that do not exceed 10-15% of the maximum intensity. When it becomes necessary to include higher signal levels the associated error in the activation energy increases. In the present work we introduced a new correction factor for the activation energy obtained by the initial rise method in terms of the percentage of maximum intensity and the geometrical factor of the glow peak. The new expression reflects the dependence of the correction factor on the order of kinetics through the geometrical factor, especially when high signal levels are involved in the analysis. With this correction, the initial rise method can be applied to signal levels up to 70% of the maximum intensity with errors lower than those encountered in applying the classical method at low intensity levels (~10% of the maximum intensity). In addition, the order of kinetics was evaluated based on the difference between the corrected value of E and the one obtained by the initial rise method. The present procedure was applied to the glow curve of Li2 B4 O7 :Mn single crystal. The obtained parameters show very good agreement with curve fitting, peak shape methods and the published data on this material which supports the validity and reliability of the present approach. PMID- 30288910 TI - Sexual dimorphism in immunity across animals: a meta-analysis. AB - In animals, sex differences in immunity are proposed to shape variation in infection prevalence and intensity among individuals in a population, with females typically expected to exhibit superior immunity due to life-history trade offs. We performed a systematic meta-analysis to investigate the magnitude and direction of sex differences in immunity and to identify factors that shape sex biased immunocompetence. In addition to considering taxonomic and methodological effects as moderators, we assessed age-related effects, which are predicted to occur if sex differences in immunity are due to sex-specific resource allocation trade-offs with reproduction. In a meta-analysis of 584 effects from 124 studies, we found that females exhibit a significantly stronger immune response than do males, but the effect size is relatively small, and became non-significant after controlling for phylogeny. Female-biased immunity was more pronounced in adult than immature animals. More recently published studies did not report significantly smaller effect sizes. Among taxonomic and methodological subsets of the data, some of the largest effect sizes were in insects, further supporting previous suggestions that testosterone is not the only potential driver of sex differences in immunity. Our findings challenge the notion of pervasive biases towards female-biased immunity and the role of testosterone in driving these differences.

PMID- 30288912 TI - Cell Wall Proteome Investigation of Bread Wheat (Triticum Aestivum) Developing Grain in Endosperm and Outer Layers. AB - The remodeling of cell wall polysaccharides is controlled by cell wall proteins (CWPs) during the development of wheat grain. This work describes for the first time the cell wall proteomes of the endosperm and outer layers of the wheat developing grain, which have distinct physiological functions and technological uses. Altogether 636 nonredundant predicted CWPs are identified with 337 proteins in the endosperm and 594 proteins in the outer layers, among which 295 proteins are present in both tissues, suggesting both common and tissue specific remodeling activities. These proteins are distributed into eight functional classes. Approximatively a quarter of them were predicted to act on cell wall polysaccharides, with many glycosylhydrolases and also expansin, lyases, and carbohydrate esterases. Therefore, these results provide crucial data to go further in the understanding of relationship between tissue-specific morphogenesis and cell wall remodeling in cereals.

AB - PURPOSE: The aim of this study was to evaluate the utility of merged balanced steady-state free precession (bSSFP) magnetic resonance cisternography images. MATERIALS AND METHODS: Twenty ears of 10 healthy volunteers (six men, four women; mean age +/- standard deviation, 26.7 +/- 1.6 yr) and 10 patients (two men, eight women; mean age, 46.3 +/- 10.9 yr) with neoplasm around the sella turcica were included. Two different devices (A and B) were used to confirm the versatility of our method for MR devices with different local magnetic field homogeneity. Images with different central frequencies (+/-10, +/-20, +/-30, +/-40, and +/-50 Hz) were merged with the maximum magnitude of corresponding pixels from the images acquired using both devices. Two neuroradiologists visually graded the image quality of 11 sites in the inner ear and three sites around the sella turcica (scale: 0-2) and compared the quality with that of the corresponding basic image (0 Hz). RESULTS: The image quality was better in merged images of the vestibule, superior semicircular canal (SCC), posterior SCC, and horizontal SCC (P = 0.005 to 0.020 mainly at +/-40 and +/-50 Hz on devices A and B), as well as in merged images of the sella turcica and right cavernous sinus (+/-50 Hz, P = 0.003 and 0.020 on device B, respectively), than it was in the corresponding basic images. CONCLUSIONS: The maximum magnitude merging of images with different central frequencies makes it possible to reduce banding artifacts on bSSFP images without the need for special pulse sequences and image processing programs. PMID- 30288918 TI - Extended follow-up for prostate cancer incidence and mortality among participants in the Prostate, Lung, Colorectal and Ovarian randomized cancer screening trial. AB - OBJECTIVE: To examine prostate cancer (PCa) incidence and mortality by arm in the randomized Prostate, Lung, Colorectal and Ovarian (PLCO) cancer screening trial. PATIENTS AND METHODS: Patients aged 55-74 years at 10 screening centres were randomized between 1993 and 2001 to an intervention or usual care arm. Patients in the intervention arm received six annual prostate-specific antigen (PSA) tests and four annual digital rectal examinations. The patients were followed for PCa incidence and for mortality via active follow-up processes and by linkage to state cancer registries and the National Death Index. For cancers identified through active follow-up, trial abstractors recorded the mode of diagnosis (screen-detected, symptomatic, other). RESULTS: A total of 38 340 patients were randomized to the intervention arm and 38 343 to a usual care arm. The median follow-up for mortality was 16.9 (intervention) and 16.7 years (usual care). There were 333 (intervention) and 352 (usual care) PCa cancer deaths, giving rates (per 10 000 person-years) of 5.5 and 5.9, respectively, and a rate ratio (RR) of 0.93 (95% confidence interval [CI] 0.81-1.08; P = 0.38). The RR for overall PCa incidence was 1.05 (95% CI 1.01-1.09). The RRs by Gleason category were 1.17 (95% CI 1.11-1.23) for Gleason 2-6, 1.00 (95% CI 0.93-1.07) for Gleason 7 and 0.89 (95% CI 0.80-0.99) for Gleason 8-10 disease. By mode of detection, during the trial's screening phase, 13% of intervention arm vs 27% of usual care arm cases were symptomatic; post-screening, these percentages were 18% in each arm. CONCLUSION: After almost 17 years of median follow-up, there was no significant reduction in PCa mortality in the intervention compared with the usual care arm. There was a significant increase in Gleason 2-6 disease and a significant reduction in Gleason 8-10 disease in the intervention compared with the usual care arm. PMID- 30288919 TI - Canonical Wnt/beta-catenin and Notch signaling regulate animal/vegetal axial patterning in the cephalochordate amphioxus. AB - In bilaterians, animal/vegetal axial (A/V) patterning is a fundamental early developmental event for establishment of animal/vegetal polarity and following specification of the germ layers (ectoderm, mesoderm, endoderm), of which the evolutionary origin is enigmatic. Understanding A/V axial patterning in a basal animal from each phylum would help to reconstruct the ancestral state of germ layer specification in bilaterians and thus, the evolution of mesoderm, the third intermediate cell layer. Herein, data show that the canonical Wnt/beta-catenin (cWnt) and Notch signaling pathways control mesoderm specification from the early endomesoderm in the basal chordate amphioxus. Amphioxus belongs to the deuterostome, one of the main superphyla in Bilateria. In the present study, genes (tcf, dsh, axin, gsk3beta) encoding cWnt components were expressed in the endomesoderm during the gastrula stages. Excess cWnt signaling by BIO, a GSK3 inhibitor, expanded the expression domains of outer endomesodermal genes that include future mesodermal ones and suppressed inner endomesodermal and ectodermal genes. Interfering Notch signaling by DAPT, a gamma-secretase inhibitor, resulted in decreased expression of ectodermal and endomesodermal markers. These results suggest that cWnt and Notch have important roles in mesoderm specification in amphioxus embryos. The evolution of the mesoderm is also discussed. PMID- 30288920 TI - Gender-Specific Body Areas Satisfaction and Body Weight Status in Adolescents: Mediating Effects of Physical Activity, Fruit and Vegetable Intake, and Energy Dense Food Intake. AB - BACKGROUND: Body satisfaction is one of the key modifiable cognitive determinants of eating behaviours, physical activity, and body mass index (BMI). As the sociocultural models suggest, low body satisfaction may explain unhealthy eating and exercise behaviours. Importantly, body satisfaction levels and body areas that individuals focus on vary across genders. This study aims at investigating links between the global index of body areas satisfaction (BAS), gender-specific BAS, fruit and vegetable (F&V) intake, energy-dense foods intake, moderate-to vigorous physical activity (MVPA), and BMI. METHODS: In all, 1,254 adolescents completed questionnaires and had their weight and height objectively measured with 2- and 13-month follow-ups. Indirect effects of three indices of BAS were tested in three models (male-specific BAS amongst boys; female-specific BAS amongst girls; the global BAS index in the total sample). RESULTS: Higher levels of all three BAS indices indirectly predicted lower BMI, with higher MVPA mediating this effect. In addition, higher energy-dense foods intake mediated higher global BAS-higher BMI relationship in the total sample. Thus, the global index of BAS acts as double-edged sword, predicting both higher MVPA and energy dense foods intake. CONCLUSION: BAS may operate in a complex manner, predicting behaviours which may have opposite effects on BMI.

AB - Crustaceans of the order Notostraca (Branchiopoda) are distributed worldwide and are known for the remarkable morphological stasis between their extant and Permian fossil species. Moreover, these crustaceans show relevant ecological traits and a wide range of reproductive strategies. However, genomic studies on notostracans are fairly limited. Here, we present the genome sequences of two notostracan taxa, Lepidurus arcticus and Lepidurus apus lubbocki. Taking advantage of the small genome sizes (~0.11 pg) of these taxa, genomes were sequenced for one individual per species with one run on the Illumina HiSeq X platform. We finally assembled 73.2 Mbp (L. arcticus) and 90.3 Mbp (L. apus lubbocki) long genomes. Assemblies cover up to 84% of the estimated genome size, with a gene completeness >97% for both genomes. In total, 13%-16% of the assembled genomes consist of repeats, and based on read mapping, L. apus lubbocki shows a significantly lower transposable element content than L. arcticus. The analysis of 2,376 orthologous genes indicates an ~7% divergence between the two Lepidurus taxa, with a nucleotide substitution rate significantly lower than that of Daphnia taxa. Ka /Ks analysis suggests purifying selection in both branchiopod lineages, raising the question of whether the low substitution rate of Lepidurus is correlated with morphological conservation or is linked to specific biological traits. Our analysis demonstrates that, in these organisms, it is possible to obtain high-quality draft genomes from single individuals with a relatively low sequencing effort. This result makes Lepidurus and Notostraca interesting models for genomic studies at taxonomic, ecological and evolutionary levels. PMID- 30288923 TI - Influence of glaucoma surgery on visual function: a clinical cohort study and meta-analysis. AB - PURPOSE: To determine the cost (loss of visual function associated with the procedure) and benefit (long-term preservation of the visual field) of glaucoma surgery. METHODS: We included 100 patients who underwent glaucoma surgery (Baerveldt glaucoma implant [BGI], n = 61; trabeculectomy [TE], n = 39). Preoperatively, the median (interquartile range [IQR]) standard automated perimetry mean deviation (MD) was -12 (-16 to -6) dB. We analysed the change in visual acuity (BCVA) and MD due to the procedure and, in a subset with at least 5 years of perimetric follow-up both pre- and postoperatively (n = 20), the change in rate of progression (ROP; time rate of change in MD). For the surgery-induced change in ROP, we also performed a meta-analysis including the current and previously published studies. From the surgery-induced decrease in MD and change in ROP, we calculated the average postoperative duration needed for the benefit to surpass the cost. RESULTS: Mean (standard deviation) MD decline was 1.3 (2.7) and 1.0 (2.3) dB for BGI (p < 0.001) and TE (p = 0.009), respectively; no significant surgery-induced changes in BCVA were found (p = 0.08 and p = 0.12, respectively). In our study, surgery was associated with a non-significant deceleration of ROP (from -0.37 [0.52] to -0.15 [0.48] dB/year; p = 0.23). The meta-analysis, based on eight studies, showed an overall surgery-induced change in ROP of 0.44 (95% confidence interval 0.25 to 0.64; p < 0.0001) dB/year. CONCLUSION: Glaucoma surgery significantly reduces the progression velocity in glaucoma. On average, the benefit of glaucoma surgery surpasses the cost after approximately 1.5 years.

AB - PURPOSE: To investigate the association between objectively measured ambient light exposure and longitudinal axial length changes (and their seasonal variations) over a period of 12 months in young adults. METHODS: This prospective longitudinal observational study included 43 healthy young adult university students (21 emmetropes and 22 myopes) aged between 18 and 30 years. Three axial length measurements were collected at 6-month intervals (i.e. at baseline, 6 and 12 months), in summer and winter to determine the axial eye growth. Personal ambient light exposure data were measured in winter and summer months with wearable sensors, from which the mean daily time exposed to bright (outdoor) light levels (>1000 lux) was derived. RESULTS: Greater daily bright light exposure was associated with less axial eye growth (beta = -0.002, p = 0.006) over 12 months. In summer, myopes exhibited significantly greater changes in axial length (mean change 0.04 +/- 0.05 mm) compared to emmetropes (-0.01 +/- 0.05 mm) (p = 0.001), but there was no significant difference between refractive groups in winter. Emmetropes also spent significantly greater time in outdoor light levels in summer compared to winter (p < 0.0001), while myopes spent similar time outdoors during both seasons (p = 0.12). Differences in light exposure between summer and winter were also associated with seasonal differences in axial eye growth (p = 0.026). CONCLUSION: In young adults, greater time spent in bright light was associated with slower longitudinal axial eye growth. Seasonal light exposure and axial length changes were dependent on refractive error in this population and also exhibited an inverse relationship. PMID- 30288927 TI - Inhibition of F1 -ATPase from Trypanosoma brucei by its regulatory protein inhibitor TbIF1. AB - Hydrolysis of ATP by the mitochondrial F-ATPase is inhibited by a protein called IF1 . In the parasitic flagellate, Trypanosoma brucei, this protein, known as TbIF1 , is expressed exclusively in the procyclic stage, where the F-ATPase is synthesizing ATP. In the bloodstream stage, where TbIF1 is absent, the F-ATPase hydrolyzes ATP made by glycolysis and compensates for the absence of a proton pumping respiratory chain by translocating protons into the intermembrane space, thereby maintaining the essential mitochondrial membrane potential. We have defined regions and amino acid residues of TbIF1 that are required for its inhibitory activity by analyzing the binding of several modified recombinant inhibitors to F1 -ATPase isolated from the procyclic stage of T. brucei. Kinetic measurements revealed that the C-terminal portion of TbIF1 facilitates homodimerization, but it is not required for the inhibitory activity, similar to the bovine and yeast orthologs. However, in contrast to bovine IF1 , the inhibitory capacity of the C-terminally truncated TbIF1 diminishes with decreasing pH, similar to full length TbIF1 . This effect does not involve the dimerization of active dimers to form inactive tetramers. Over a wide pH range, the full length and C-terminally truncated TbIF1 form dimers and monomers, respectively. TbIF1 has no effect on bovine F1 -ATPase, and this difference in the mechanism of regulation of the F-ATPase between the host and the parasite could be exploited in the design of drugs to combat human and animal African trypanosomiases. PMID- 30288928 TI - Raw regulates glial population of the eye imaginal disc. AB - Glia are critical for proper development, support, and function of the nervous system. The Drosophila eye has proven an excellent model for gaining significant insight into the molecular mechanisms regulating glial development and function. Recent studies have demonstrated that Raw is required in glia of the central and peripheral nervous systems; however, the function of Raw in glia of the developing eye has not been explored. These studies demonstrate that raw knockdown results in a reduction in the number of glia in the third instar eye imaginal disc and reduced glial spreading across the field of differentiating photoreceptor neurons. Expression of a raw enhancer trap reveals that raw is expressed in eye disc glia. Exploration of the mechanism by which raw knockdown results in glial reduction reveals that Raw is required for glial proliferation and migration into the eye disc. In addition, Raw negatively regulates Jun N terminal kinase (JNK) signaling in glia of the developing eye and increased JNK signaling results in a reduction in the number of glia populating the eye disc, similar to that observed upon raw knockdown. Thus, Raw functions as a critical regulator of glial population of the eye imaginal disc by regulating glial proliferation and migration and inhibiting JNK signaling.

AB - Cyclin-dependent kinase (CDK4/6) inhibitors in combination with endocrine therapy are currently the optimal first line treatment for hormone receptor (HR) positive, human epidermal growth factor receptor 2 (HER2) non-amplified metastatic breast cancer (MBC). However, not all patients benefit from this treatment and all patients will inevitably progress. Identifying therapeutic strategies in this setting is therefore of immediate clinical importance. We present an overview of the mechanisms of resistance to CDK4/6 inhibitors and review potential biomarkers that may guide therapy selection. We also discuss the use of CDK4/6 inhibitors in the context of non-HR-positive/HER2-non-amplified breast cancer and in combination with therapies other than endocrine therapy. PMID- 30288930 TI - Hormone receptor positive, HER2 negative metastatic breast cancer: Impact of CDK4/6 inhibitors on the current treatment paradigm. AB - Resistance to endocrine therapy is a significant therapeutic challenge in the treatment of women with hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) advanced breast cancer. Cyclin-dependent kinase (CDK)4/6 inhibitors in combination with endocrine therapy have been shown to improve progression free survival, overall response rate and clinical benefit rate in women with HR+ HER2- metastatic breast cancer compared with endocrine therapy alone. This review examines the clinical evidence to support the use of CDK4/6 inhibitors in first and second line settings. Practical guidance is provided for the use of CDK4/6 inhibitors, including tolerability data, monitoring requirements and management of key toxicities for each of the available agents.

AB - The rational design of electrochemically and mechanically stable Si anodes is of great importance for the development of high energy density lithium-ion batteries. In this study, patterned Si-based (Si/ZnO/C) trilayer composite films were synthesized by magnetron sputtering with the assistance of a patterned mask. The electron-conductive C layer at the top of the composite film is deposited to enhance the interfacial stability between active film and electrolyte. The ion- and electron-conductive Li2 O-Zn middle layer can be ingeniously introduced by means of the poor reversed conversion reaction between ZnO and Li+ ions after the first cycle. The resultant Si/Li2 O-Zn/C trilayer composite film delivers a high reversible capacity of 1536 mAh g-1 after 800 cycles at a current density of 1.0 A g-1 and a long high-rate cycling stability (1400 mAh g-1 after 6000 cycles even at a high current density of 10.0 A g-1 ). Excellent rate capability and improved Coulombic efficiency are also achieved. The influences of the patterned structure and each modified layer on the electrochemical properties are analyzed systematically. This work offers a new and promising direction to enhance the lithium-storage properties of Si-based thin-film anodes. PMID- 30288932 TI - The Neuropeptide Secretoneurin Exerts a Direct Effect on Arteriogenesis In Vivo and In Vitro. AB - It is well known that nerves modulate the development and remodeling of blood vessels by releasing different neuropeptides and neurotransmitters. Secretoneurin (SN), a neuropeptide located in nerve fibers along blood vessels, acts as a pro angiogenic agent and induces postnatal vasculogenesis. However, little is known about its involvement in arteriogenesis. In the present study, we tested the hypothesis that SN promotes arteriogenesis in a rat model of hind limb ischemia, as such, we evaluated the effect of this neuropeptide on proliferation and the production of adhesion and chemotaxis molecules in vascular smooth muscle cells (VSMCs), the main component that carries the burden of the transformation of a small arteriole into a large collateral vessel. In vivo, SN-immunoreactive nerve fibers were abundantly distributed in the adventitia of the collateral vessel. Moreover, administration of SN induced cell proliferation in the vascular wall and the infiltration of inflammatory cells/macrophages to promote collateral vessel growth. This was shown by an increased density of arterioles/arteries, together with a well-developed network of collateral vessels, and well-preserved skeletal muscles. In vitro, SN exerted proliferative effects on VSMCs and stimulated these cells to express adhesion molecules. In conclusion, our data demonstrate for the first time that SN acts as a mediator of inflammation, contributing to collateral vessel growth, in addition to directly stimulating cell proliferation in the vascular wall to promote collateral vessel growth in a rat model of hind limb ischemia.

AB - Rabies virus (RABV) does not persist in the environment as it is a very fragile agent. The primary hosts are mammalian species in the orders Carnivora and Chiroptera. Since the late 1980s, RABV has been isolated from non-human primates, Callithrix jacchus (the white-tufted marmoset), in four coastal states (Rio Grande do Norte, Ceara, Piaui and Pernambuco) in north-eastern Brazil, where this species is indigenous. The original habitat of C. jacchus consisted of two Brazilian biomes, the Atlantic Forest and the Caatinga. However, these marmosets have since adapted to other ecosystems as a result of human activities. Between 1988 and 1989, RABV isolates were obtained from white-tufted marmosets in the state of Rio Grande do Norte, but antigenic and genetic identification studies were not conducted at that time. In the following years, three additional states reported cases (Ceara, Piaui and Pernambuco). In two of these states (Ceara and Piaui), human cases of rabies transmitted by marmosets were reported. According to Brazilian Health Ministry data, at least 19 human cases in which this species was the source of infection were registered in between 1990 and 2016. Recent findings in laboratory tests of 12 rabid samples from humans and marmosets and the regional transmission among these animals for over 20 years, together with the gradual increase in the affected geographic area, support the concept of the emergence of a new RABV reservoir. Regional tourism, the wild animal trade and the cultural practice of maintaining these animals as pets, particularly in coastal regions, appear to be major risk factors for the increase in human cases. Additional epidemiological and ecological studies are required to better understand local disease dynamics and to identify ideal opportunities for prevention and control of this fatal infection. PMID- 30288934 TI - Rapid determination of anticoagulating effects of dabigatran in whole blood with rotational thromboelastometry and a thrombin-based trigger. AB - Essentials A rapid test to detect thrombin inhibition by dabigatran would be valuable in acute situations. A thrombin-based trigger was applied in whole blood using rotation thromboelastometry. Effects of dabigatran were assessed in vitro and in samples from patients on dabigatran. The test produced data rapidly and was sensitive to dabigatran concentrations from 20 to 500 ng mL-1 . SUMMARY: Background Rapid determination of the anticoagulant effect of dabigatran is essential in emergency situations. Objective To study a viscoelastic test (rotational thromboelastometry [ROTEM]) for rapid determination of dabigatran effects in whole blood samples. Method ROTEM measurements were performed with comparison of two triggers (thrombin-based versus the commercial tissue factor based trigger Ex-tem) in samples from 10 healthy donors spiked with dabigatran (20-500 ng mL-1 ) and in samples from 35 patients receiving dabigatran treatment; 10 healthy subjects served as controls. Clotting time (CT) and the difference in CT without versus with addition of the dabigatran antidote idarucizumab (CTdiff ) were measured. Addition of idarucizumab reveals the contribution of dabigatran to ROTEM measurements and its potential reversibility. Results In vitro studies showed that thrombin CT and thrombin CTdiff were more sensitive than Ex-tem CT and Ex-tem CTdiff in detecting dabigatran in whole blood samples. In patient samples, when thrombin CT and thrombin CTdiff were used, it was possible to detect dabigatran with a cut-off of dabigatran at 20 ng mL-1 , whereas, when Ex tem CT and Ex-tem CTdiff were used, the method was less sensitive. Data from patient samples were obtained within 15 min of blood sampling. Conclusions ROTEM CT with a thrombin-based trigger is more sensitive to dabigatran effects than Ex tem CT, and detects anticoagulant effects of drug concentrations in the low-very low therapeutic range. Analysis with idarucizumab (CTdiff ) reveals dabigatran specific effects. As data are rapidly obtained, this method could, with further development and validation of its performance, be suitable for detecting clinically significant dabigatran effects in emergency situations.

AB - Infection by HIV-1 requires protein-protein interactions involving gp120, CD4 and CCR5. We have previously demonstrated that the transferred nuclear Overhauser effect (TRNOE), in combination with asymmetric deuteration of a protein and a peptide ligand can be used to detect intermolecular interactions in large protein complexes with molecular weights up to ~ 100 kDa. Here, using this approach, we reveal interactions between tyrosine residues of a 27-residue peptide corresponding to the N-terminal segment of the CCR5 chemokine receptor, and a dimeric extended core YU 2 gp120 envelope protein of HIV-1 complexed with a CD4 mimic miniprotein. The TRNOE crosspeaks in the ternary complex were assigned to the specific Tyr protons in the CCR5 peptide and to methyl protons of isoleucine, leucine and/or valine residues of gp120. Site directed mutagenesis combined with selective deuteration and TRNOE resulted in the first discernment by a biophysical method of specific pairwise interactions between gp120 residues in the bridging sheet of gp120 and the N-terminus of CCR5. PMID- 30288936 TI - GammaKnife versus VMAT radiosurgery plan quality for many brain metastases. AB - The purpose of this work was to compare dose distributions between two radiosurgery modalities, single-isocenter volumetric modulated arc therapy (VMAT), and GammaKnife Perfexion (GK), in the treatment of a large number (>=7) of brain metastases. Twelve patients with 103 brain metastases were analyzed. The median number of targets per patient was 8 (range: 7-14). GK plans were compared to noncoplanar VMAT plans using both 6-MV flattening filter-free (FFF) and 10-MV FFF modes. Parameters analyzed included radiation therapy oncology group conformity index (CI), 12, 6, and 3 Gy isodose volumes (V12 Gy, V6 Gy, V3 Gy), mean and maximum hippocampal dose, and maximum skin dose. There were statistically significant differences in CI (2.5 +/- 1.6 vs 1.6 +/- 0.8 and 1.7 +/- 0.9, P < 0.001, P < 0.001), V12 Gy (2.8 +/- 6.1 cc vs 3.0 +/- 5.2 cc and 3.1 +/- 5.4 cc, P = 0.003, P < 0.001), and V3 Gy (323.0 +/- 294.8 cc vs, 880.1 +/- 369.1 cc and 937.9 +/- vs 361.9 cc, P = 0.005, P = 0.001) between GK versus both 6-MV FFF and 10-MV FFF. No significant differences existed for maximum hippocampal or skin doses. In conclusion, highly optimized VMAT produced improved conformity at the expense of a higher V12 Gy and V3 Gy volume when compared with highly optimized GK. PMID- 30288937 TI - The effects of endogenous and exogenous catecholamines on hypoxic cardiac performance in red-bellied piranhas. AB - Catecholamines protect the fish heart during hypoxia. However, the humoral adrenergic stress response may only be invoked in extremis. We investigated the hypothesis that endogenous (e.g., neuronal) myocardial catecholamines may also impact cardiac performance during hypoxia in a hypoxia-tolerant tropical fish, the red-bellied piranha (Pygocentrus nattereri). First, we measured endogenous tissue catecholamines and in vitro catecholamine release from piranha myocardium using ultraperformance liquid chromatography. Ventricle homogenates contained detectable levels of both adrenaline (7.27 ng/g) and noradrenaline (14.48 ng/g), but only noradrenaline was released from ventricular tissue incubated in Ringer's solution. Noradrenaline released in this assay was not affected by hypoxia but was promoted by the catecholamine releasing agent tyramine. Our second series of experiments explored cardiac contractile performance in vitro using tyramine, exogenous noradrenaline or adrenaline, and propranolol (a beta-adrenoceptor antagonist). In ventricular strip preparations, beta-adrenergic blockade with propranolol had no effects on twitch force or contraction kinetics in either normoxia or hypoxia, confirming that spontaneous endogenous catecholamine release did not impact cardiac performance. However, in the absence of propranolol, tyramine mimicked the positive inotropic effect of noradrenaline (10 uM) during hypoxia, although adrenaline was capable of generating larger effects. Our results suggest that, although it is not spontaneously released, inducible endogenous noradrenaline release may have a significant beta-adrenoceptor dependent impact on hypoxic performance in the fish heart. PMID- 30288938 TI - Clinical outcomes among morbidly obese patients hospitalized with diabetic foot complications. AB - The aim of the study is to investigate effects of morbid obesity on patients hospitalized with diabetic foot ulcers and infections (DFU/Is). This retrospective cohort study of hospitalized adults investigated patients with a principal diagnosis of DFU/Is, and compared outcomes based on weight. The primary outcome was lower limb amputations. Secondary outcomes included in-hospital mortality, morbidity (sepsis and discharge disposition), resource utilization (length of stay [LOS] and total hospitalization charges). Multivariate analyses adjusted for confounders. A total of 31 730 admissions were included; 14% were morbidly obese. Patients with morbid obesity had overall lower rates of amputations (adjusted odds ratio [aOR]: 0.60; 95% confidence interval [CI]: 0.45 0.80). There was no difference in mortality rates between those who were morbidly obese and the non-morbidly obese patients (aOR: 3.89 [95% CI: 0.79-19.30]). Combined data from 2010 to 2014 have found higher odds of sepsis in morbidly obese patients compared with non-morbidly obese patients after adjusting for confounders (aOR: 1.49 [1.09-2.02], P = 0.01). Patients with morbid obesity were less likely to be discharged to home (aOR: 0.82 [95% CI: 0.70-0.95]), had longer LOS (adjusted mean difference [aMD]: 0.47 [95% CI: 0.13-0.81]) and higher hospital charges (aMD: $3205 [95% CI: $3373-$6037]). Despite having lower amputation rates compared to those who are not morbidly obese, patients with morbid obesity hospitalized for DFU/Is succumbed to sepsis more frequently and had less favourable utilization metrics. Specialized care pathways may be needed to enhance the value of care delivered to this high-risk population. PMID- 30288939 TI - Change in subfoveal choroidal thickness secondary to orthokeratology and its cessation: a predictor for the change in axial length. AB - PURPOSE: To investigate changes in subfoveal choroidal thickness (SFChT) during orthokeratology (Ortho-K) lens wear and after its cessation and the association of short-term change in SFChT with the long-term eye elongation in Ortho-K subjects. DESIGN: A prospective clinical trial. METHODS: Fifty myopic children aged between 9 and 14 years were enrolled. Twenty-nine subjects continuously wore Ortho-K lens for 12 months and discontinued for 1 month. Twenty-one subjects wearing single vision distance spectacles for 12 months were included as the control group. SFChT was assessed using optical coherence tomography. Ocular parameters, including axial length (AL), central corneal thickness (CCT), anterior chamber depth (ACD), lens thickness (LT) and apical corneal power (ACP), were also measured. RESULTS: After 12 months of follow-up, AL elongation was larger and SFChT change was smaller in the control group compared to the Ortho-K group (both p < 0.001). In the Ortho-K group, SFChT increased by 16 MUm from baseline at the 1-month visit (p < 0.001), and the magnitude of choroidal thickening remained unchanged at the 6- and 12-month visit (p = 0.289). One month after discontinuation of Ortho-K lens, SFChT and ocular parameters of the anterior segment, including ACP, CCT and ACD recovered to baseline level (All p > 0.05), and AL increased by 0.23 +/- 0.18 mm compared to baseline (p = 0.018). SFChT change at 1-month was negatively associated with AL change at 13-month (standard beta, -0.581, p = 0.001) after adjusting for other influencing factors, including baseline age and the ocular parameters. CONCLUSION: Subfoveal ChT (SFChT) significantly increased after short-term Ortho-K lens treatment and the increase maintained throughout the period of treatment. One month after Ortho-K lens cessation, SFChT, ACP, CCT and ACD returned to baseline. Short-term response in SFChT is associated with long-term change in AL in children undergoing Ortho-K lens and may be a predictor for the effectiveness of the treatment. PMID- 30288940 TI - A Direct Approach for Process Development Using Single Column Experiments Results in Predictable Streamlined Multi-Column Chromatography Bioprocesses. AB - An emphasis on continuous monoclonal antibody (mAb) bioprocessing in the pharmaceutical industry necessitates effective approaches for downstream process development (PD). With a PD strategy, the process parameters are optimized to directly develop streamlined three-step continuous chromatography processes. A design of experiment (DoE) approach with single column (batch mode) is used to simulate a multi-column (continuous mode) purification method and characterize each chromatography step: Protein A capture, anion exchange, and mixed mode cation exchange. A novel and targeted approach to quickly characterize a DoE design space was employed and empirical modeling was used to define the capacity for multi-column chromatography to accurately transfer the batch process to continuous mode of purification. This PD approach effectively mimics the continuous mode of operation and provides the flexibility to develop multiple continuous processes with target mAb recovery and purity. By implementing this PD strategy and the process parameters defined in batch mode, two robust and predictable continuous bioprocesses were developed within 7 weeks of investigation, which resulted in a total product yield of recovery at or above 74%, host cell protein (HCP) content below 5 ppm, and aggregate content below 1%.

AB - The domestic swine eye resembles the human eye both anatomically and physiologically. Xenotransplantation of the swine cornea to humans in need of full keratoplasty shows promise as a potential therapeutic strategy to restore vision in individuals with advanced corneal disease, especially those residing in developing nations. That said, we characterized the morphology of corneas from miniature swine, which are smaller in size, easier to handle, and more cost effective compared to domestic swine. Eyes (N = 15) were harvested from miniature swine from different age groups: 1 month (N = 3), 2 month (N = 3), 4 month (N = 3), 8 month (N = 3), as well as 24 month old adult domestic swine (N = 3). They were immediately submerged in fixative and processed for histological examination at the light and transmission electron microscopic level. Gross anatomic measurements of the cornea were significantly less (P value <= 0.05) in miniature swine versus domestic swine. Corneal strata exhibited morphological characteristics similar to the domestic swine cornea. Adult miniature swine corneas show similar overall corneal thickness at 8 months of age versus domestic swine. Miniature swine exhibit similar corneal morphology with the domestic pig and humans, with the exception of Bowman's layer, which is absent in pigs. Therefore, miniature pigs may be a useful resource of corneal tissue for humans in need of full keratoplasty, as well as serve as a large eye model for ophthalmology residents to develop surgical skills and for development and testing of ocular therapeutic strategies that translate to humans.

PMID- 30288946 TI - Plasma markers of chronic low-grade inflammation in polypoidal choroidal vasculopathy and neovascular age-related macular degeneration. AB - PURPOSE: Ageing is the strongest predictor of neovascular age-related macular degeneration (AMD), where neuroinflammation is known to play a major role. Less is known about polypoidal choroidal vasculopathy (PCV), which is an important differential diagnosis to neovascular AMD. Here, we report plasma markers of inflammation with age (inflammaging) in patients with PCV, patients with neovascular AMD and a healthy age-matched control group. METHODS: We isolated plasma from fresh venous blood obtained from participants (n = 90) with either PCV, neovascular AMD, or healthy maculae. Interleukin(IL)-1beta, IL-6, IL-8, IL 10 and tumour necrosis factor receptor 2 (TNF-R2) were measured using U-PLEX Human Assays. Routine plasma C-reactive protein (CRP) was measured using Dimension Vista 1500. RESULTS: Patients with PCV had plasma levels of IL-1beta, IL-6, IL-8, IL-10 and TNF-R2 similar to that in healthy controls. Patients with neovascular AMD had significantly higher plasma IL-1beta, IL-6 and IL-10 than healthy controls, whereas no significant differences were observed for plasma IL 8 and TNF-R2. Differences between plasma IL-1beta, IL-6 and IL-10 possessed a positive but weak ability in discriminating neovascular AMD from PCV. Both patients with PCV and patients with neovascular AMD had significantly higher levels of routine plasma CRP. CONCLUSION: Patients with PCV differ from patients with neovascular AMD in terms of plasma inflammaging profile. Apart from increased CRP, no signs of inflammaging were observed in patients with PCV. In patients with neovascular AMD, we find a specific angiogenesis-twisted inflammaging profile. PMID- 30288947 TI - Ranking the stars. PMID- 30288948 TI - pH/Redox-Triggered Photothermal Treatment for Cancer Therapy Based on a Dual Responsive Cationic Polymer Dot. AB - In the present study, a pH/redox-responsive cationic polymer dot (CD) was successfully prepared for a near-infrared (NIR)-mediated, simultaneously controllable photothermal temperature guided imaging off/on system to monitor therapeutic delivery. Carbonized disulfide cross-linked branched polyethyleneimine (bPEI) was conjugated with folic acid (FA) as a targeting moiety and partially formed an ionic complex with anionic indocyanine green (ICG) to afford a bPEI-based CD (ICG-CD). This was responsive to mild reductive (glutathione, GSH) and acidic tumor conditions, which enabled the simultaneous biodegradation of those hydrophobic and complex sites. The ICG-CD internalized readily into the cytoplasm of cancer cells by a FA receptor and cationic-mediated endocytosis in the off state, whereas if ICG-CD met intracellular GSH at high concentrations, GSH contributed partially to the recovery of fluorescence and was then internalized into acidic endosomes to induce complete restoration of fluorescence. This tumor-sensitive degradability of the CD not only facilitated ICG release in the tumor location but also allowed controllable photothermal therapy effects of nanoparticles under NIR irradiation, which resulted in improved cancer therapy. Taken together, the results indicate great potential in tumor targeting, intracellular imaging, and controllable therapeutic delivery through a fluorescence off/on assay under the pH/redox conditions of cancer cells. PMID- 30288949 TI - Collagen chirality and three-dimensional orientation studied with polarimetric second-harmonic generation microscopy. AB - Polarization-dependent second-harmonic generation (P-SHG) microscopy is used to characterize molecular nonlinear optical properties of collagen and determine a three-dimensional (3D) orientation map of collagen fibers within a pig tendon. C6 symmetry is used to determine the nonlinear susceptibility tensor components ratios in the molecular frame of reference chizzz2/chizxx2 and chixyz2/chizxx2 , where the latter is a newly extracted parameter from the P-SHG images and is related to the chiral structure of collagen. The chixyz2/chizxx2 is observed for collagen fibers tilted out of the image plane, and can have positive or negative values, revealing the relative polarity of collagen fibers within the tissue. The P-SHG imaging was performed using a linear polarization-in polarization-out (PIPO) method on thin sections of pig tendon cut at different angles. The nonlinear chiral properties of collagen can be used to construct the 3D organization of collagen in the tissue and determine the orientation-independent molecular susceptibility ratios of collagen fibers in the molecular frame of reference. PMID- 30288950 TI - Imbalances in tissue inhibitors of metalloproteinases differentiate choroidal neovascularization from geographic atrophy. AB - PURPOSE: Tissue inhibitor of metalloproteinase (TIMP) is known to play a role in age-related macular degeneration (AMD). We wished to investigate alterations in different late stages of AMD: neovascular AMD and geographic atrophy (GA). METHODS: This was a prospective case-control study. A total of 125 participants were included consecutively during a period of 18 months. We included 46 patients with neovascular AMD, 46 patients with GA without any sign of choroidal neovascularization in either eye, and 33 healthy aged controls. Patients with immune-affecting disorders were not included. Commercial immunoassay kits were used to quantify levels of TIMP-1, TIMP-3, MMP-2 and MMP-9 in blood plasma. RESULTS: We found that patients with neovascular AMD had lower plasma concentration of TIMP-3 (p = 0.028) than healthy controls. Patients with GA had higher plasma levels of TIMP-1 (p < 0.001) and MMP-9 (p = 0.022) compared to healthy controls. Also, we found that TIMP-1 levels in patients with GA increased with age (Spearman's rho = 0.04, p = 0.006). CONCLUSION: Matrix metalloproteinases (MMPs) and TIMPs, which are known to be involved in age related changes in Bruch's membrane, are significantly altered systemically, suggesting the presence of an imbalance in the homeostasis of the extracellular matrix. These imbalances may explain differences in the clinical manifestation of late AMD. PMID- 30288951 TI - Tobacco Mosaic Virus as a Versatile Platform for Molecular Assembly and Device Fabrication. AB - Viruses are unique biological agents that infect living host cells through molecular delivery of a genomic cargo. Over the past two decades advancements in genetic engineering and bioconjugation technologies have allowed the unprecedented use of these "unfriendly" biological molecules, as nanoscopic platforms for the advancement of an array of nanotechnology applications. This mini-review focuses on providing a brief summary of key demonstrations leveraging the versatile characteristics of Tobacco mosaic virus (TMV) for molecular assembly and bio-device integration. A comprehensive discussion of genetic and chemical modification strategies along with potential limiting factors that impact the assembly of these macromolecules is presented to provide useful insights for adapting TMV as a potentially universal platform toward developing advanced nanomaterials. Additional discussions on biofabrication techniques developed in parallel to enable immobilization, alignment, and patterning of TMV based functional particles on solid surfaces will highlight technological innovations that can be widely adapted for creating nanoscopic device components using these engineered biomacromolecules. Further exploitation in the design of molecular specificity and assembly mechanisms and the development of highly controllable and scalable TMV-device integration strategies will expand the library of nanoscale engineering tools that can be used for the further development of virus-based nanotechnology platforms. PMID- 30288952 TI - Evaluating the yield of gastrointestinal testing in pediatric patients in aerodigestive clinic. AB - OBJECTIVE: To improve understanding of the interrelatedness of airway and esophageal diagnoses by evaluating the yield of procedural and radiographic testing of the gastrointestinal tract in children with airway conditions by their referring diagnoses in a pediatric aerodigestive clinic. METHODS: A retrospective chart review of all 325 patients seen in the aerodigestive program from 2010 to 2013 was performed in a single academic medical center. Demographics and results from esophagogastroduodenoscopies with biopsies (EGD), upper gastrointestinal fluoroscopy studies (UGI), and pH multichannel intraluminal impedance probe (pH MII) performed within 30 days of the clinic visit were evaluated according to presenting diagnoses. RESULTS: Mean patient age was 3.15 years (range 0.15-24 years) and 41.2% were born premature. 189/325 (58.1%) were on acid suppression. A total of 295 EGD, 193 pH-MII, and 54 UGI were performed. The most common diagnosis with an abnormal pH-MII was asthma. The most common diagnoses with an abnormal EGD were feeding difficulty and tracheal esophageal fistula/ esophageal atresia (TEF/EA). EGDs were normal in 188/295 (63.7%), while 39/295 (13.2%) demonstrated esophagitis, and 22/295 (7.5%) had >15 esophageal eosinophils per high power field. The majority of pH-MII (144/193 [74.6%]) and UGI (47/54 [87%]) were normal. CONCLUSIONS: Children with feeding difficulty, TEF/EA, and asthma were the mostly likely to have a histologic abnormality on EGD or an abnormal pH MII. The majority of children were previously prescribed acid suppression medication and had a referring diagnosis of gastroesophageal reflux disease but were subsequently found to have normal evaluation. Prospective studies are needed to optimize care of this population. PMID- 30288953 TI - Hand Factors in Cardiac Development. AB - Congenital heart defects account for 1% of infant mortality and 10% of in utero deaths. As the vertebrate embryo develops, multiple tissue types develop in tandem to morphologically pattern the functional heart. Underlying cardiac development is a network of transcription factors known to tightly control these morphological events. Members of the Twist family of basic helix-loop-helix transcription factors, Hand1 and Hand2, are essential to this process. The expression patterns and functional role of Hand factors in neural crest cells, endocardium, myocardium, and epicardium is indicative of their importance during cardiogenesis; however, to date, an extensive understanding of the transcriptional targets of Hand proteins and their overall mechanism of action remain unclear. In this review, we summarize the recent findings that further outline the crucial functions of Hand factors during heart development and in post-natal heart function. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30288954 TI - A repeated cross-sectional study of the epidemiology of Campylobacter and antimicrobial resistant Enterobacteriaceae in free-living Canada geese in Guelph, Ontario, Canada. AB - From May through October 2016, we conducted a repeated cross-sectional study examining the effects of temporal, spatial, flock and demographic factors (i.e. juvenile vs. adult) on the prevalence of Campylobacter and antimicrobial resistant Enterobacteriaceae among 344 fresh faecal samples collected from Canada geese (Branta canadensis) from four locations where birds nested in Guelph, Ontario, Canada. The overall prevalence of Campylobacter among all fresh faecal samples was 9.3% and was greatest in the fall when these birds became more mobile following the nesting season. Based on 40 gene comparative genomic fingerprinting (CGF40), the increase in prevalence noted in the fall was matched by an increase in the number of unique CGF40 subtypes identified. Resistance to colistin was detected most commonly, in 6% of Escherichia coli isolates, and was highest in the late summer months. All colistin-resistant isolates were negative for the mcr 1 to mcr-5 genes; a chromosomal resistance mechanism (PmrB) was identified in all of these isolates. The prevalence of samples with E. coli exhibiting multi-class resistance or extended spectrum beta-lactamase was low (i.e. <2% of samples). The intra-class correlation coefficients, estimated from the variance components of multilevel logistic regression models, indicated that the shedding of Campylobacter and antimicrobial resistant E. coli among geese within a flock (i.e. birds collected from the same site on the same day) was moderately correlated. Spatial, temporal, and spatiotemporal clusters identified using the spatial scan statistic, largely supported the findings from our multi-level models. Salmonella was not isolated from any of the fresh faecal samples collected suggesting that its prevalence in this population of birds was very low.

AB - The gastrointestinal tract of the alpaca (Vicugna pacos) is most efficiently adapted to its habitat at high altitudes. Alpacas, just like ruminants, feed on hardly digestible forage. However, it has been demonstrated that the anatomy of the camelid digestive tract has developed independently of ruminants and not in homology to them. Despite a long history of domestication and an increasing number of animals worldwide, little research has been done on the intestinal anatomy of alpacas. The purpose of this study was to describe the anatomical features of the alpaca's intestines and to explain anatomical peculiarities in the context of evolutionary function and morphology. Another goal of this study was the demonstration of weaknesses of the intestinal anatomy predisposing alpacas to certain clinical presentations. Six animals were used for dissection. The basic structure of the intestines was comparable to that in ruminants. However, a number of characteristic peculiarities were found in alpacas, like the duodenal ampulla and the proximal and distal loop of the ascending colon. The jejunum and ileum, unlike those of ruminants, had their own mesentery largely separated from the ascending mesocolon. The main blood supply was provided by the cranial and caudal mesenteric artery. The particular lymph nodes were located along the branches of these two arteries. The spiral colon seemed to play a major role in intestinal digestion and water resorption. The size of the distal fermentation chamber allows the presumption that alpacas belong to the group of animals practicing a fractionated fermentation in the proximal and distal fermentation chambers.

AB - The space between cardiac myocytes is commonly referred-to as the cardiac interstitium (CI). The CI is a unique, complex and dynamic microenvironment in which multiple cell types, extracellular matrix molecules, and instructive signals interact to crucially support heart homeostasis and promote cardiac responses to normal and pathologic stimuli. Despite the biomedical and clinical relevance of the CI, its detailed cellular structure remains to be elucidated. In this review, we will dissect the organization of the cardiac interstitium by following its changing cellular and molecular composition from embryonic developmental stages to adulthood, providing a systematic analysis of the biological components of the CI. The main goal of this review is to contribute to our understanding of the CI roles in health and disease. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30288957 TI - Filamin-A as a Balance between Erk/Smad Activities during Cardiac Valve Development. AB - Mitral valve prolapse (MVP) affects 2.4% of the population and has poorly understood etiology. Recent genetic studies have begun to unravel the complexities of MVP and through these efforts, mutations in the FLNA (Filamin-A) gene were identified as disease causing. Our in vivo and in vitro studies have validated these genetic findings and have revealed FLNA as a central regulator of valve morphogenesis. The mechanisms by which FLNA mutations result in myxomatous mitral valve disease are currently unknown, but may involve proteins previously associated with mutated regions of the FLNA protein, such as the small GTPase signaling protein, R-Ras. Herein, we report that Filamin-A is required for R-Ras expression and activation of the Ras-Mek-Erk pathway. Loss of the Ras/Erk pathway correlated with hyperactivation of pSmad2/3, increased extracellular matrix (ECM) production and enlarged mitral valves. Analyses of integrin receptors in the mitral valve revealed that Filamin-A was required for beta1-integrin expression and provided a potential mechanism for impaired ECM compaction and valve enlargement. Our data support Filamin-A as a protein that regulates the balance between Erk and Smad activation and an inability of Filamin-A deficient valve interstitial cells to effectively remodel the increased ECM production through a beta1-integrin mechanism. As a consequence, loss of Filamin-A function results in increased ECM production and generation of a myxomatous phenotype characterized by improperly compacted mitral valve tissue. Anat Rec, 2018.

AB - In this study, we examined the structure of the heart of the whale shark, Rhincodon typus, using a plastination technique and three-dimensional X-ray computer tomography (3DCT). Inspection of the atrium revealed a symmetric distribution of the pectinate muscles attached to the commissures of the sino atrial valve, suggesting some functional advantages. The majority of the ventricular wall comprised spongiosa, and compacta accounted for only ~3% of the entire thickness. There were three major fiber orientations in the spongiosa: the fibers on the endocardial side formed trabeculae that were aligned with the blood flow tract, whereas those on the epicardial side formed a circular pattern around the flow tract. Transmural myofibers connected the inner and outer layers in the spongiosa, which may serve as an intraventricular conduction pathway. Plastination and 3DCT is a powerful combination that allowed for multifaceted visualization of the internal structure of rare heart specimens in a nondestructive manner.

PMID- 30288960 TI - Light at night affects hippocampal and nidopallial cytoarchitecture: Implication for impairment of brain function in diurnal corvids. AB - Our previous studies have shown that light at night (LAN) impaired cognitive performance and affected neurogenesis and neurochemistry in the cognition associated brain regions, particularly the hippocampus (HP) and lateral caudal nidopallium (NCL) of Indian house crows (Corvus splendens). Here, we examined the cytoarchitecture and mapped out the morphology of neurons and glia-neuron density in HP and NCL regions of crows that were first entrained to 12-hr light (LL): 12 hr darkness (LD) and then exposed to the light regime in which 12-hr darkness was either replaced by daytime light (i.e., constant light, LL) or by dim light (i.e., dim light at night, dLAN), with controls continued on LD 12:12. Compared with LD, there was a significant decrease in the soma size, suggesting reduced neuronal plasticity without affecting the neuronal density of both HP and NCL of crows under LL and dLAN conditions. In parallel, we found a reduced number of glia cells and, hence, decreased glia-neuron ratio positively correlated with soma size in both, HP and NCL regions. These results for the first time demonstrate LAN-induced negative effects on the brain cytoarchitecture of a diurnal species and give insight for possible influence on the brain health and functions in animals including humans that might be inadvertently exposed to LAN in an emerging night-illuminated urban environment.

AB - BACKGROUND: Perilipin2 (Plin2) belongs to a family of five highly conserved proteins, known for their role in lipid storage. Recent data indicate that Plin2 has an important function in cell metabolism and is involved in several human pathologies, including liver steatosis and Type II diabetes. An association between Plin2 and lower muscle mass and strength has been found in elderly and inactive people, but its function in skeletal muscle is still unclear. Here, we addressed the role of Plin2 in adult muscle by gain and loss of function experiments. METHODS: By mean of in vivo Plin2 down-regulation (shPlin2) and overexpression (overPlin2) in murine tibialis anterior muscle, we analysed the effects of Plin2 genetic manipulations on myofiber size and lipid composition. An analysis of skeletal muscle lipid composition was also performed in vastus lateralis samples from young and old patients undergoing hip surgery. RESULTS: We found that Plin2 down-regulation was sufficient to induce a 30% increase of myofiber cross-sectional area, independently of mTOR pathway. Alterations of lipid content and modulation of genes involved in lipid synthesis occurred in hypertrophic muscles. In particular, we showed a decrease of triglycerides, ceramides, and phosphatidylcoline:phosphatidylethanolamine ratio, a condition known to impact negatively on muscle function. Plin2 overexpression did not change fibre size; however, lipid composition was strongly affected in a way that is similar to that observed in human samples from old patients. CONCLUSIONS: Altogether these data indicate that Plin2 is a critical mediator for the control of muscle mass, likely, but maybe not exclusively, through its critical role in the regulation of intracellular lipid content and composition. PMID- 30288962 TI - Uterine Receptivity in Merriam's Kangaroo Rat (Dipodomys merriami). AB - The uterine surface undergoes significant remodeling, termed the "plasma membrane transformation," during pregnancy to allow for implantation of the blastocyst and formation of the placenta in viviparous amniote vertebrates. Unlike other species within the superorder Euarchontoglires, which have a hemochorial (highly invasive) placenta, kangaroo rats (Dipodomys spp.) exhibit a less invasive endotheliochorial placenta. We characterized the changes that occur to membrane molecules and the cellular ultrastructure of the uterine epithelium during early pregnancy in Merriam's kangaroo rat, Dipodomys merriami using electron microscopy and immunofluorescence microscopy. Epithelial cadherin (E-cadherin) is an adhesion protein that forms the adherens junction and is localized to the lateral plasma membrane of uterine epithelium during the nonreproductive state but localizes nonspecifically in the uterine epithelium immediately preceding implantation. Desmosomes are a type of cadherin that form junctional complexes along the lateral plasma membrane of epithelium. Dsg-2, a marker for desmosomes, is localized along the lateral plasma membrane in non-pregnant animals but redistributes to the apical region of the lateral plasma membrane during early pregnancy. The shift in desmosome and cadherin distribution before implantation suggests that there is a reduction in lateral adhesion between epithelial cells to allow for invasion by the blastocyst. Surprisingly, although Kangaroo rats form a less invasive placenta, these same changes occur during pregnancy in species with highly invasive placentation, such as the laboratory rat and human. These commonalities suggest that it is not through the retention of lateral adhesion that the blastocyst is prevented from further invasion in this rodent species. Anat Rec, 301:1928-1935, 2018.

AB - BACKGROUND: Research about exercise adherence amongst adults with arthritis has been largely correlational, and theoretically based causal studies are needed. We used an experimental design to test the social cognitive theory premise that high self-efficacy helps to overcome challenging barriers to action. METHODS: Exercising individuals (N = 86; female = 78%; M age = 53; BMI = 27) with differential self-regulatory efficacy for managing salient, non-disease barriers were randomly assigned to many or few barrier conditions. Individuals responded about the strength of their anticipated persistence to continue exercise, and their self-regulatory efficacy to use exercise-enabling coping strategies. RESULTS: In the many barriers condition, higher barriers-efficacy individuals expressed (a) greater persistence (Cohen's d = 0.75 [-0.029, 1.79]) and (b) more confidence in their coping solutions (Cohen's d = 0.65 [-0.30, 1.60]) than lower barriers-efficacy counterparts. CONCLUSION: Experimental support was obtained for the theoretical premise that when facing the greatest barrier challenge, individuals highest in self-regulatory efficacy still view exercise as possible. Findings suggest that identifying lower efficacy exercisers with arthritis to tailor their exercise to increase self-regulatory efficacy might also improve their adherence.

AB - Integrating layered nanostructured MoS2 with a structurally stable TiO2 backbone to construct reciprocal MoS2 /TiO2 -based nanocomposites is an effective strategy. C@TiO2 /MoO3 composite nanofibers doped with 1T-phase MoS2 nanograins were fabricated by partially sulfurizing MoOx /TiO2 precursors. By controlling a suitable preoxidation temperature before severe thermolysis of polyvinylpyrrolidone (PVP), the MoOx /TiO2 precursors formed a polymer-embedded array through coordination of the Mo source and pyrrolidyl groups of PVP. Sulfidation under water/solvent hydrothermal conditions led to partial formation of metallic 1T-phase MoS2 from the MoOx precursor with preoxidation at 200 degrees C. After carbonization, the TiO2 /MoO3 /MoS2 nanograins were encapsulated in a carbon backbone in a vertical pattern, providing both chemical contact for confined electron transport and sufficient space to adapt to volume changes. The obtained carbon-based platform not only has the advantages of an integral structure, but also exhibited ultrastable specific capacities of 540 and 251 mAh g-1 for Li-ion batteries and Na-ion batteries, respectively, after 100 cycles.

Traditionally, a step-by-step scanning of the sample is applied to generate a Raman image, which, however, is too slow for routine examination of patients. By transferring the technique of integral field spectroscopy (IFS) from astronomy to Raman imaging, it becomes possible to record entire Raman images quickly within a single exposure, without the need for a tedious scanning procedure. An IFS-based Raman imaging setup is presented, which is capable of measuring skin ex vivo or in vivo. It is demonstrated how Raman images of healthy and cancerous skin biopsies were recorded and analyzed.

To provide reliable preclinical in vivo models of metastatic disease, this study characterized the metastatic spread of luciferase-expressing mouse pheochromocytoma (MPC) cells in mouse strains with different immunologic conditions. Bioluminescence imaging showed that, in contrast to subcutaneous non-metastatic engraftment of luciferase-expressing MPC cells in NMRI-nude mice, intravenous cell injection provided only suboptimal metastatic spread in both NMRI-nude mice and hairless SCID (SHO) mice. Treatment of NMRI-nude mice with anti-Asialo GM1 serum enhanced metastatic spread due to substantial depletion of natural killer (NK) cells. However, reproducible metastatic spread was only observed in NK cell-defective SCID/beige mice and in hairless immunocompetent SKH1 mice bearing disseminated or liver metastases, respectively. Liquid chromatography tandem mass spectrometry of urine samples showed that subcutaneous and metastasized tumor models exhibit comparable renal monoamine excretion profiles characterized by increasing urinary dopamine, 3 methoxytyramine, norepinephrine and normetanephrine. Metastases-related epinephrine and metanephrine were only detectable in SCID/beige mice. Positron emission tomography and immunohistochemistry revealed that all metastases maintained somatostatin receptor-specific radiotracer uptake and immunoreactivity, respectively. In conclusion, we demonstrate that intravenous injection of luciferase-expressing MPC cells into SCID/beige and SKH1 mice provides reproducible and clinically relevant spread of catecholamine-producing and somatostatin receptor-positive metastases. These standardized preclinical models allow for precise monitoring of disease progression and should facilitate further investigations on theranostic approaches against metastatic pheochromocytomas and paragangliomas.

AB - Solid-state nuclear magnetic resonance (SSNMR) methods have been routinely used for the characterization of both the structure and the dynamics of metal organic frameworks (MOFs), a collection of porous media investigated for potential applications in carbon capture technologies, selective separation of small molecules, and catalysis. (1) The use and development of SSNMR techniques that enable the nondestructive characterization of the adsorbed behavior have become essential steps in bettering our understanding of MOFs and are often complementary to traditional methods of structural characterization. This Review aims to give a brief introduction to the relevant concepts of SSNMR and the methods employed when investigating the phenomenon of adsorbed carbon dioxide gas in MOFs. We summarize the published SSNMR literature on CO2 in MOFs, as well as highlight the best experimental practices when working with these complex systems.

AB - Aluminum oxynitride (AlON) was commonly used in functional ceramic materials, including phosphors for white light-emitting diodes (LEDs). In the current work, a new polymorph of AlON structure, single phase [Mg1.25Si1.25Al2.5]O3N3, has been devised and synthesized through the solid-state reaction at a rather low temperature of 1550 degrees C. Its structure has been calculated by the Rietveld refinement. The [Mg1.25Si1.25Al2.5]O3N3 crystallizes in trigonal with lattice parameters of a = b = 3.0312 A, c = 41.5758 A, V = 330.83 A3, respectively, and it is formed by Mg2+ and Si4+ ions replacing partical Al3+ ions of Al5O3N3. The photoluminescence spectra of a series of Eu2+ doped [Mg1.25Si1.25Al2.5]O3N3 show a tunable light ranging from cyan to orange with a full-spectrum-covered emission and a wide excitation band with two peaks located at 290 and 335 nm. This is resulted from the two possible sites offered by the cation substitution for Eu2+ to occupy and thus broadening the emission spectra, which significantly enrich the monotonous luminescent properties of conventional AlON phosphors. Additionally, the energy transfer from one site to another has been identified using the decay curves and time-resolved emission spectra. The scanning electron microscopy and transmission electron microscopy characterization confirmed the sample's great crystallinity and the thermal stability with more than 85% of the initial intensity at 250 degrees C further indicates its potential in white LED applications. PMID- 30288973 TI - High-Throughput Open-Air Plasma Activation of Metal-Oxide Thin Films with Low Thermal Budget. AB - Sputter-processed oxide films are typically annealed at high temperature (activation process) to achieve stable electrical characteristics through the formation of strong metal-oxide chemical bonds. For instance, indium-gallium-zinc oxide (IGZO) films typically need a thermal treatment at 300 degrees C for >=1 h as an activation process. We propose an open-air plasma treatment (OPT) to rapidly and effectively activate sputter-processed IGZO films. The OPT effectively induces metal-oxide chemical bonds in IGZO films at temperatures as low as 240 degrees C, with a dwell time on the order of a second. Furthermore, by controlling the plasma-processing conditions (scan speed, distance a between plasma nozzle and samples, and gas flow rate), the electrical characteristics and the microstructure of the IGZO films can be easily tuned. Finally, OPT can be utilized to implement a selective activation process. Plasma-treated IGZO thin film transistors (TFTs) exhibit comparable electrical characteristics to those of conventionally thermal treated IGZO TFTs. Through in-depth optical, chemical, and physical characterizations, we confirm that OPT simultaneously dissociates weak chemical bonds by UV radiation and ion bombardment and re-establishes the metal oxide network by radical reaction and OPT-induced heat. PMID- 30288974 TI - Mild Reduction of the Cancer Cell Surface as an Anti-invasion Treatment. AB - Cancer cell invasion is the main reason for high mortality in patients with malignant cancers. There has been little improvement in cancer prognosis because of a high rate of infiltration. Therefore, successful treatment requires inhibition of cancer cell invasion. Here, we suggest a new approach to inhibit cancer cell invasion through mild reduction of cell surface proteins to expose free thiols. Through mild reduction, the cancer cell surfaces present free active thiols at the membranes, enhancing cell adhesion to extracellular matrix and decreasing motility. Collectively, we suggest cell surface modification as a new therapeutic approach to treat invading malignant cancers.

AB - We introduce solution-based, room temperature- and atmospheric pressure-processed silver nanocrystal (Ag NC)-based electrical circuits and interconnects for radio frequency (RF)/microwave frequency applications. We chemically designed the surface and interface states of Ag NC thin films to achieve high stability, dc and ac conductivity, and minimized RF loss through stepwise ligand exchange, shell coating, and surface cleaning. The chemical and structural properties of the circuits and interconnects affect the high-frequency electrical performance of Ag NC thin films, as confirmed by high-frequency electromagnetic field simulations. An all solution-based process is developed to build coplanar structures, in which Ag NC thin films are positioned at both sides of the substrates. In addition, we fabricated flexible transmission lines and broadband electrical circuits for resistors, interdigitated capacitors, spiral and omega shaped inductors, and patch antennas with maximum inductance and capacitance values of 3 nH and 2.5 pF at frequencies up to 20 GHz. We believe that our approach will lead to a cost-effective realization of RF circuits and devices in which sensing and wireless communication capabilities are combined for internet of-things applications.

AB - An integrated source apportionment methodology is developed by amalgamating the receptor-oriented model (ROM) and source-oriented numerical simulations (SOM) together to eliminate the weaknesses of individual SA methods. This approach attempts to apportion and dissect the PM2.5 sources in the Yangtze River Delta region during winter. First, three ROM models (CMB, PMF, ME2) are applied and compared for the preliminary SA results, with information from PM2.5 sampling and lab analysis during the winter seasons. The detailed source category contribution of SOM to PM2.5 is further simulated using the WRF-CAMx model. The two pieces of information from both ROM and SOM are then stitched together to give a comprehensive information on the PM2.5 sources over the region. With the integrated approach, the detailed contributing sources of the ambient PM2.5 at different receptors including rural and urban, coastal and in-land, northern and southern receptors are analyzed. The results are compared with previous data and shows good agreement. This integrative approach is more comprehensive and is able to produce a more profound and detailed understanding between the sources and receptors, compared with single models.

AB - Development of stimuli-responsive theranostics is of great importance for precise cancer diagnosis and treatment. Herein, bovine serum albumin (BSA) modified bismuth nanoraspberries (Bi-BSA NRs) are developed as cancer theranostic agents for multimodal imaging and chemo-photothermal combination therapy. The Bi-BSA NRs are synthesized in aqueous phase via a facile reduction method using Bi2O3 nanospheres as the sacrificial template. The morphology, biocompatibility, photothermal effect, drug loading/releasing abilities, chemotherapy effect, synergistic chemo-photothermal therapy efficacy, and multimodal imaging capacities of Bi-BSA NRs have been investigated. The results show that the NRs possess multiple unique features including (i) raspberry-like morphology with high specific surface area (~52.24 m2.g-1) and large cavity (total pore volume ~0.30 cm3.g-1), promising high drug loading capacity (~69 wt %); (ii) dual stimuli responsive drug release, triggered by acidic pH and NIR laser irradiation; (iii) infrared thermal (IRT), photoacoustic (PA) and X-ray computed tomography (CT) trimodality imaging with the CT contrast enhanced efficiency as high as ~66.7 HU.mL.mg-1; (iv) 100% tumor elimination through the combination chemo-photothermal therapy. Our work highlights the great potentials of Bi-BSA NRs as a versatile theranostics for multimodal imaging and combination therapy. PMID- 30288979 TI - Probing the Delicate Balance between Pauli Repulsion and London Dispersion with Triphenylmethyl Derivatives. AB - The long-known, ubiquitously present, and always attractive London dispersion (LD) interaction was probed with hexaphenylethane (HPE) derivatives. A series of all- meta hydrocarbyl [Me, iPr, tBu, Cy, Ph, 1-adamantyl (Ad)]-substituted triphenylmethyl (TPM) derivatives [TPM-H, TPM-OH, (TPM-O)2, TPM*] was synthesized en route, and several derivatives were characterized by single-crystal X-ray diffraction (SC-XRD). Multiple dimeric head-to-head SC-XRD structures feature an excellent geometric fit between the meta-substituents; this is particularly true for the sterically most demanding tBu and Ad substituents. NMR spectra of the iPr , tBu-, and Cy-derived trityl radicals were obtained and reveal, together with EPR and UV-Vis spectroscopic data, that the effects of all- meta alkyl substitution on the electronic properties of the trityl scaffold are marginal. Therefore, we concluded that the most important factor for HPE stability arises from LD interactions. Beyond all- meta tBu-HPE we also identified the hitherto unreported all- meta Ad-HPE. An intricate mathematical analysis of the temperature-dependent dissociation constants allowed us to extract Delta Gd298(exptl) = 0.3(5) kcal mol-1 from NMR experiments for all- meta tBu-HPE, in good agreement with previous experimental values and B3LYP-D3(BJ)/def2-TZVPP(C PCM) computations. These computations show a stabilizing trend with substituent size in line with all- meta Ad-HPE (Delta Gd298(exptl) = 2.1(6) kcal mol-1) being more stable than its tBu congener. That is, large, rigid, and symmetric hydrocarbon moieties act as excellent dispersion energy donors. Provided a good geometric fit, they are able to stabilize labile molecules such as HPE via strong intramolecular LD interactions, even in solution.

AB - Luminescent thermometers have attracted much attention, because of their fast response, high sensitivity, and noninvasive operation, relative to other traditional thermometers. The extensive studies on the temperature-dependent luminescent properties of Cu(I) complexes make this low-cost metal source a promising candidate as a component of thermometers. Herein, we prepared three luminescent phosphinine Cu(I) complexes whose emission lifetimes are precisely dependent on the temperature variations. For practical utilization, sensor films have been fabricated by doping these Cu(I) complexes into the matrices of polyacrylamide. These films not only exhibit excellent linear correlations between the temperature and emission lifetime over the wide range of 77-337 K, but also show high sensitivity (with the best one to -6.99 MUs K-1). These are essential factors for the application in luminescent molecular thermometers. Moreover, the emission mechanism for these Cu(I) complexes are rationalized by the combination of experimental and theoretical results.

AB - The dynamics of exciton quenching are critical to the operational performance of organic optoelectronic devices, but their measurement and elucidation remain ongoing challenges. Here, we present a method for quantifying small photoluminescence quenching efficiencies of organic semiconductors under steady state conditions. Exciton quenching efficiencies of three different organic semiconductors, PC70BM, P3HT, and PCDTBT, are measured at different bulk quencher densities under continuous low-irradiance illumination. By implementing a steady state bulk-quenching model, we determine exciton diffusion lengths for the studied materials. At low quencher densities we find that a secondary quenching mechanism is in effect, which is responsible for approximately 20% of the total quenched excitons. This quenching mechanism is observed in all three studied materials and exhibits quenching volumes on the order of several thousand cubic nanometers. The exact origin of this quenching process is not clear, but it may be indicative of delocalized excitons being quenched prior to thermalization. PMID- 30288983 TI - Direct in Situ Observation and Analysis of the Formation of Palladium Nanocrystals with High-Index Facets. AB - Synthesizing concave-structured nanoparticles (NP) with high-index surfaces offers a viable method to significantly enhance the catalytic activity of NPs. Current approaches for fabricating concave NPs, however, are limited. Exploring novel synthesis methods requires a thorough understanding of the competing mechanisms that contribute to the evolution of surface structures during NP growth. Here, by tracking the evolution of Pd nanocubes into concave NPs at atomic scale using in situ liquid cell transmission electron microscopy, our study reveals that concave-structured Pd NPs can be formed by the cointroduction of surface capping agents and halogen ions. These two chemicals jointly create a new surface energy landscape of Pd NPs, leading to the morphological transformation. In particular, Pd atoms dissociate from the {100} surfaces with the aid of Cl- ions and preferentially redeposit to the corners and edges of the nanocubes when the capping agent polyvinylpyrrolidone is introduced, resulting in the formation of concave Pd nanocubes with distinctive high-index facets. Our work not only demonstrates a potential route for synthesizing NPs with well defined high-index facets but also reveals the detailed atomic-scale kinetics during their formation, providing insight for future predictive synthesis. PMID- 30288984 TI - Exploring the neurocognitive correlates of challenging behaviours in young people with autism spectrum disorder. AB - Many young people with autism spectrum disorder display 'challenging behaviours', characterised by externalising behaviour and self-injurious behaviours. These behaviours can have a negative impact on a young person's well-being, family environment and educational achievement. However, the development of effective interventions requires greater knowledge of autism spectrum disorder-specific models of challenging behaviours. Autism spectrum disorder populations are found to demonstrate impairments in different cognitive domains, namely social domains, such as theory of mind and emotion recognition, but also non-social domains such as executive functioning and sensory or perceptual processing. Parent-rated self injurious behaviour and externalising behaviours, and neurocognitive performance were assessed in a population-derived sample of 100 adolescents with autism spectrum disorder. Structural equation modelling was used to estimate associations between cognitive domains (theory of mind, emotion recognition, executive functioning and perceptual processing) and self-injurious behaviour and externalising behaviours. Poorer theory of mind was associated with increased self-injurious behaviour, whereas poorer perceptual processing was associated with increased externalising behaviours. These associations remained when controlling for language ability. This is the first analysis to examine how a wide range of neurocognitive domains relate to challenging behaviours and suggests specific domains that may be important targets in the development of interventions in adolescents with autism spectrum disorder. PMID- 30288986 TI - Technology in Public Health Higher Education. AB - Streamed and recorded lectures as well as audience response technology are increasingly used in public health tertiary education, to train practitioners to address Asia-Pacific region's rapidly changing health needs. However, little is known about the impact on student performance, satisfaction, and understanding. This study aimed to assess postgraduate students' perceptions and their use of technology in a large epidemiology subject at an Australian university in internal and external modes. The study used both routinely collected student data (n = 453) and survey data (n = 88). Results indicate that students accept and use technology-based learning tools, and perceive audience response technology as well as streamed and recorded lectures as useful for their learning (96.6%). Students have shown a preference to review recorded lectures rather than viewing streamed lectures. Analyses further suggest that the use of recorded and streamed lectures may be linked to better student performance for external students (passing, any use odds ratio = 3.32). However, these effects are not consistent across all student subgroups and externally enrolled students may profit more than those enrolled internally. PMID- 30288985 TI - Measurement Equivalence and Convergent Validity of a Mental Health Rating Scale. AB - Emotional and behavioral problems among children and adolescents may be studied using the Strengths and Difficulties Questionnaire, containing five subscales, based on ratings by parents, teachers, or adolescents themselves. We investigate two measurement issues using data from a longitudinal sample of 8,806 participants aged 7 to 9 years and 11 to 13 years from the Bergen Child Study in Bergen, Norway. First, convergent validity of parent and teacher ratings is studied using a multitrait-multimethod approach. Second, longitudinal measurement equivalence is studied using confirmatory factor analysis, which requires us to deal with the considerable attrition. The multitrait-multimethod indicates not only good convergent validity but also considerable method variance for parents and teachers. The reliability and validity of some subscales are relatively low. Attrition analysis indicates that attrition is not missing completely at random, but estimation assuming missing at random makes no real difference. We conclude that assuming missing completely at random is acceptable. Comparing ratings by parents and teachers results in partial scalar equivalence. In addition, all subscales exhibit (partial) longitudinal scalar measurement equivalence. We recommend using latent variable modeling and not summated scales for longitudinal modeling using the Strengths and Difficulties Questionnaire.

PMID- 30288988 TI - Exploring and building autism service capacity in rural and remote regions: Participatory action research in rural Alberta and British Columbia, Canada. AB - Based in participatory action research, this project had the aim of building capacity in treatment and support for individuals and families impacted by autism spectrum disorder in remote and rural communities of Canada. Communities were selected based on their rurality and willingness to engage in change efforts for enhanced service delivery within their region. Fifteen discussion groups with key stakeholders were convened in seven communities with ~200 community stakeholders. Based on analyses of these data from the stakeholders, themes were distilled through interpretive description, which in turn were presented to community stakeholders for reflection and collective action. Findings indicate broad thematic domains consisting of: insufficient services, protective factors in community, change efforts via collectivity within community, limitations and benefits of residing in rural communities relative to care associated with autism spectrum disorder, a sense of "community" in rural contexts, and engaging in focused dialogue as a pathway to advancement. Opportunities for building capacity for support in autism spectrum disorder emerged within intersecting layers of leadership, contextual factors, and community collaboration. Consistent with participatory action research principles, emerging local knowledge was supported with strategies for improved autism spectrum disorder service development. PMID- 30288989 TI - Adults with autism spectrum condition have atypical perception of ambiguous figures when bottom-up and top-down interactions are incongruous. AB - We examined the perception of an ambiguous squares stimulus evoking bistable perception in a sample of 31 individuals with autistic spectrum condition and 22 matched typical adults. The perception of the ambiguous figure was manipulated by adaptation to unambiguous figures and/or by placing the ambiguous figure into a context of unambiguous figures. This resulted in four conditions testing the independent and combined (congruent and incongruent) manipulations of adaptation (bottom-up) and spatial context (top-down) effects. The strength of perception, as measured by perception of the first reported orientation of the ambiguous stimulus, was affected comparably between groups. Nevertheless, the strength of perception, as measured by perceptual durations, was affected differently between groups: the perceptual effect was strongest for the autistic spectrum condition group when combined bottom-up and top-down conditions were congruent. In contrast, the strength of the perceptual effect in response to the same condition in the typical adults group was comparable to the adaptation, but stronger than both the context and the incongruent combined bottom-up and top-down conditions. Furthermore, the context condition was stronger than the incongruent combined bottom-up and top-down conditions for the typical adults group. Thus, our findings support the view of stimulus-specific top-down modulation in autistic spectrum condition.

PMID- 30288991 TI - Quadriceps Function and Patient-Reported Outcomes After Anterior Cruciate Ligament Reconstruction in Patients With or Without Knee Osteoarthritis. AB - CONTEXT: Relationships between quadriceps function and patient-reported outcomes after anterior cruciate ligament reconstruction (ACLR) are variable and may be confounded by including patients at widely different time points after surgery. Understanding these relationships during the clinically relevant phases of recovery may improve our knowledge of specific factors that influence clinical outcomes. OBJECTIVE: To identify the relationships between quadriceps function and patient-reported outcomes in patients <2 years (early) and >2 years (late) after ACLR, including those with posttraumatic knee osteoarthritis. DESIGN: Cross sectional study. SETTING: Laboratory. PATIENTS OR OTHER PARTICIPANTS: A total of 72 patients after ACLR: early (n = 34, time from surgery = 9.0 +/- 4.3 months), late (n = 30, time from surgery = 70.5 +/- 41.6 months), or osteoarthritis (n = 8, time from surgery = 115.9 +/- 110.0 months). MAIN OUTCOME MEASURE(S): The total Knee Injury and Osteoarthritis Outcome Score (KOOS) and Veterans RAND 12 Item Health Survey (VR-12) were used to quantify knee function and global health. Predictors of patient-reported outcomes were involved-limb and symmetry indices of quadriceps function (isokinetic strength [peak torque, total work, average power], maximum voluntary isometric contraction torque, fatigue index, central activation ratio, Hoffmann reflex, active motor threshold) and demographics (age, activity level, pain, kinesiophobia, time since surgery). Multiple linear regression analyses were used to predict KOOS and VR-12 scores in each group. RESULTS: In the early patients, knee-extensor work, active motor threshold symmetry, pain, and activity level explained 67.8% of the variance in the KOOS score ( P < .001); knee-extensor work, activity level, and pain explained 53.0% of the variance in the VR-12 score ( P < .001). In the late patients, age and isokinetic torque symmetry explained 28.9% of the variance in the KOOS score ( P = .004). In the osteoarthritis patients, kinesiophobia and isokinetic torque explained 77.8% of the variance in the KOOS score ( P = .010); activity level explained 86.4% of the variance in the VR-12 score ( P = .001). CONCLUSIONS: Factors of muscle function and demographics that explain patient-reported outcomes were different in patients early and late after ACLR and in those with knee osteoarthritis.

AB - There has been accumulating evidence that several micronutrients may play a protective role in the risk of solid cancers. However, their role in hematological malignancies remains to be elucidated; this meta-analysis aims to evaluate the associations between micronutrient intake as well as supplementation and risk of hematological cancer in adults. Eligible cohort studies (examining intake of vitamin A, vitamin C, vitamin D, vitamin E, lycopene, folate, iron, carotenoids, beta-carotene, selenium, pyridoxine) were sought in PubMed up to July 31, 2016. Random-effects models were used for the calculation of pooled relative risks (RR) with their 95% confidence intervals (CI). Twelve cohort studies were deemed eligible. Null associations were noted regarding supplemented vitamin A (pooled relative risk [RR] = 0.92, 95% confidence interval [CI]: 0.80 1.07), supplemented vitamin C (pooled RR = 1.00, 95%CI: 0.90-1.12), total vitamin D (pooled RR = 1.05, 95%CI: 0.91-1.20), supplemented vitamin E (pooled RR = 0.98, 95%CI: 0.88-1.10), and dietary lycopene intake (pooled RR = 1.00, 95%CI: 0.86 1.16) and the risk of non-Hodgkin lymphoma. No summary estimates are provided for other hematological malignancies due to the limited number of studies. Future prospective trials should be conducted for a better understanding of this field; especially regarding Hodgkin lymphoma, leukemia and plasma cell neoplasms, on which data are scarce. PMID- 30288995 TI - Betulinic acid improves insulin sensitivity, hyperglycemia, inflammation and oxidative stress in metabolic syndrome rats via PI3K/Akt pathways. AB - This study investigated the influence of betulinic acid on high-fructose diet induced metabolic syndrome in rats. Oral administration of betulinic acid significantly reversed high-fructose diet-mediated increase in body mass index and blood glucose. Furthermore, betulinic acid restored high-fructose diet mediated alterations in metabolic hormones (insulin, leptin and adiponectin). Betulinic acid-mediated upregulation of protein kinase B (Akt) and phosphoinositde-3 kinase (PI3K) anulled high-fructose diet mediated depletion. Also, elevated tumour necrosis factor-alpha, interleukin-6 and -8 were significantly lowered. Administration of betulinic acid restored high-fructose diet-mediated increase in the levels of lipid profile parameters and indices of atherosclerosis, cardiac and cardiovascular diseases. High-fructose diet-mediated decrease in activities of antioxidant enzymes (superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase and glucose 6-phosphate dehydrogenase) and increase in oxidative stress biomarkers (reduced glutathione, lipid peroxidation products, protein oxidation and fragmented DNA) were significantly restored by the phenolic acids. Conclusively, betulinic acid improves insulin sensitivity, elevated blood glucose, inflammation and dyslipidaemia and oxidative stress in high-fructose diet-induced metabolic syndrome through the PI#Kand Akt pathways . PMID- 30288996 TI - Inhibition of Nf-?b prevents trauma-induced heterotopic ossification in rat model. AB - PURPOSE: To investigate the pathogenesis and find a better prophylactic method of acquired heterotopic ossification (HO). MATERIALS AND METHODS: In the first part, we designed the brain-traumatic/burn/tenotomy rat model and testified its efficacy as HO model. 44 rats were randomly divided into experimental group and control group. After operation, the bilateral tendons of 2 rats were collected at the 2nd, 3rd, 4th, 6th, 8th, and 10th weeks to determine the expression levels of p65. Additionally, the remaining rats were exposed to X-Ray examination at the 10th week. In the second part, 124 rats were randomly divided into four groups based on the administration dosage of Ammonium pyrrolidinedithiocarbamate (PDTC). Then, three rats of each group were euthanized every week in the first seven weeks to collect tendon to detect the expression levels of p65 by qRT-PCR and Western Blot. The remaining rats were exposed to X-Ray examination at the 10th week to assess the size of HO before being euthanized for HE staining. RESULTS: The success rate of Brain-traumatic/Burn/Tenotomy model was 100%. Pharmacologic inhibition of Nf-?b signaling pathway by PDTC could significantly reduce the expression levels of p53 and the size of HO, and the reduction was most significant in the 0.6mg dosage group. CONCLUSIONS: Brain-traumatic/Burn/Tenotomy model was highly reliable HO model. Inhibition of Nf-?b signaling pathway by PDTC could significantly reduce HO formation, and the most effective concentration was 6 mg/ml for local injection. PMID- 30288997 TI - Deep learning and virtual drug screening. AB - Current drug development is still costly and slow given tremendous technological advancements in drug discovery and medicinal chemistry. Using machine learning (ML) to virtually screen compound libraries promises to fix this for generating drug leads more efficiently and accurately. Herein, we explain the broad basics and integration of both virtual screening (VS) and ML. We then discuss artificial neural networks (ANNs) and their usage for VS. The ANN is emerging as the dominant classifier for ML in general, and has proven its utility for both structure-based and ligand-based VS. Techniques such as dropout, multitask learning and convolution improve the performance of ANNs and enable them to take on chemical meaning when learning about the drug-target-binding activity of compounds. PMID- 30288998 TI - Chemokine and Adhesion Molecule Profiles in Aqueous Humor of Clinically Quiescent Uveitic Cataracts. AB - PURPOSE: To investigate the chemokine and adhesion molecule profiles in aqueous humor (AH) of eyes with inactive uveitis and their correlations with inflammation relapse after cataract surgery. METHODS: Patients with inactive uveitis who underwent cataract surgery between July 2014 and January 2016 at our center were included. Undiluted AH samples (100-120 ul) were obtained through lateral corneal incisions during surgery, and concentrations of monocyte chemoattractant protein 1 (MCP-1/CCL2), macrophage inflammatory protein 1 (MIP-1), interleukin 8 (IL-8), regulated on activation, normal T cell expressed and secreted (RANTES/CCL5), soluble vascular cell adhesion molecule (sVCAM) and soluble intercellular adhesion molecule (sICAM) were measured by cytometric bead array (BD Bioscience, San Jose, CA). AH levels of these inflammatory factors were compared between different uveitis entities and non-inflammatory control. Risk factors for postoperative inflammation relapse were also analysed in uveitic eyes. RESULTS: As compared with the control group, the panuveitis group had significantly higher aqueous concentrations of MCP-1, IL-8, sVCAM, sICAM; the anterior uveitis group had significantly higher concentrations of MCP-1, MIP-1, sVCAM. Uveitic cataracts with postoperative inflammation relapse had significantly higher levels of MCP-1 and IL-8 in AH than those without. And multivariate cox regression analysis revealed that high AH levels of MCP-1 was an independent predictor for postoperative inflammation relapse. CONCLUSIONS: Clinically quiescent uveitic eyes have elevated levels of chemokines and soluble adhesion molecules in AH, of which MCP-1 is associate with inflammation relapses after cataract surgery. PMID- 30288999 TI - Women's Experiences of Day-and-Night Closed-Loop Insulin Delivery During Type 1 Diabetes Pregnancy. AB - AIMS:: Closed-loop insulin delivery has the potential to improve day-to-day glucose control in type 1 diabetes pregnancy. However, the psychosocial impact of day-and-night usage of automated closed-loop systems during pregnancy is unknown. Our aim was to explore women's experiences and relationships between technology experience and levels of trust in closed-loop therapy. METHODS:: We recruited 16 pregnant women with type 1 diabetes to a randomized crossover trial of sensor augmented pump therapy compared to automated closed-loop therapy. We conducted semistructured qualitative interviews at baseline and follow-up. Findings from follow-up interviews are reported here. RESULTS:: Women described benefits and burdens of closed-loop systems during pregnancy. Feelings of improved glucose control, excitement and peace of mind were counterbalanced by concerns about technical glitches, CGM inaccuracy, and the burden of maintenance requirements. Women expressed varied but mostly high levels of trust in closed-loop therapy. CONCLUSIONS:: Women displayed complex psychosocial responses to day-and-night closed-loop therapy in pregnancy. Clinicians should consider closed-loop therapy not just in terms of its potential impact on biomedical outcomes but also in terms of its impact on users' lives. PMID- 30289000 TI - Antimicrobial pentacyclic triterpenes and glycosides from the stem bark of Cussonia bancoensis. AB - The stem bark of Cussonia bancoensis is used traditionally for the treatment of different types of infection and pain. A bioassay guided fractionation of the methanol stem bark extract led to the isolation of five pentacyclic triterpenes and glycosides identified based on spectroscopic data as 23-hydroxyursolic acid (CB1), hederagenin (CB2), 3-O-alpha-L-arabinopyranosyl-echinocystic acid (CB3), 3 O-alpha-L-arabinopyranosyl- oleanolic acid (CB4) and 3-O-alpha-L-arabinopyranosyl ursolic acid (CB5). CB2 - CB5 are being reported for the first time from this species. The compounds were evaluated for antimicrobial activity against ten microorganisms using the HT-SPOTi method. CB3 demonstrated remarkable antimicrobial activity against S. aureus, S. pyogens, E. faecalis, S. typhi and C. albicans at MICs between 3.12 and 12.5 ug/mL. Among the studied compounds, it was observed that hydroxylation of position C-16 of the oleanane skeleton may enhance antimicrobial activity. This study gives insight into the anti-infective constituents of the stem bark of C. bancoensis and justifies its use in ethnomedicine. PMID- 30289002 TI - Phylogeny and acoustic signal evolution of a pure tone song katydid Pseudophyllus titan (Orthoptera: Tettigoniidae) based on the complete mitogenome. AB - Ensifera is an extremely diverse group in the order Orthoptera, and it has been the subject of considerable research, especially in terms of phylogeny and bioacoustics. Katydids are known for using high-frequency broadband signals whereas most cricket songs are pure tones with a frequency range of 2-8 kHz. Pseudophyllus titan is a special katydid emits low-frequency pure tone songs similar to that of crickets. Acoustic communication of Ensifera were widely studied, but song evolution could deserve new examination taking into account the newly available phylogenies. To examine the song evolution of P. titan in the Ensifera, the mitogenomes of P. titan and three other ensiferan species (Sphagniana ussuriana, Oecanthus sinensis, Truljalia hibinonis) were obtained by high-throughput sequencing. In addition, the phylogeny of Ensifera was reconstructed including 63 in-group taxa, and the divergence time was further estimated for major ensiferan lineages. Lastly, the evolutions of song frequency were evaluated based on an ancestral character state reconstruction (ACSR). Moreover, we have studied the calling songs of 78 katydids and performed ACSR based on five genes. All phylogeny analyses confirmed that the superfamily Schizodactyloidea was placed basally to the non-grylloid clade. P. titan was in the Pseudophyllinae clade, and this clade had a distant relationship form other lineages in Phaneropteridae. The ACSR showed that P. titan evolved low-frequency pure tone songs independently after ancestors of katydids evolved high-frequency broadband noise. Referring to the geologic time scale, we suggest that the song frequency evolution in the Ensifera to some extent caused by adaptations to the changing habitat under conditions of climate change and plant evolution. PMID- 30289001 TI - Extended Sinus Tarsi Approach for Treatment of Displaced Intraarticular Calcaneal Fractures Compared to Extended Lateral Approach. AB - BACKGROUND: We compared the radiographic results and clinical outcomes of patients operated on via the extended sinus tarsi approach (ESTA) and the extended lateral approach (ELA) for treatment of displaced intraarticular calcaneal fractures. METHODS: We retrospectively studied the utility of the ELA (46 patients, 52 feet) and the ESTA (56 patients, 64 feet) in patients operated on between January 2009 and March 2015. We evaluated pre- and postoperative x rays and computed tomography (CT) data. Pain, patient-reported functional outcomes, satisfaction, and postoperative complications were investigated at the 3-year follow-up. RESULTS: Neither the postoperative nor 3-year follow-up Bohler angles, nor the calcaneal width, differed significantly between the 2 groups (both P > .05). However, the maximum step-off of the posterior facet on the 3 month CT follow-up of the ESTA group was significantly less than that of the ELA group ( P < .05). We found no significant between-group differences in terms of postoperative translation ( P = .232) or angulation ( P = .132) of the sustentacular fragment on the 3-month CT follow-up. At the 3-year follow-up, we found no significant between-group difference in the mean visual analog scale pain score at rest ( P = .641) or during weightbearing ( P = .525). We found no significant between-group difference in the Foot Function Index (FFI) ( P = .712) or self-reported satisfaction ( P = .823). The ELA group experienced significantly more wound complications ( P = .041) and nonunions ( P = .041) than the ESTA group. Four instances of superficial peroneal nerve injury were reported in the ESTA group ( P = .127). CONCLUSION: Compared with the ELA, the ESTA afforded comparable, favorable radiological results and clinical outcomes, associated with fewer wound complications and nonunions. We suggest that the ESTA is an effective operative option when treating displaced, intraarticular calcaneal fractures. LEVEL OF EVIDENCE: Level III, comparative study. PMID- 30289003 TI - Vitamin B12 buccoadhesive tablets: auspicious non-invasive substitute for intra muscular injection: formulation, in vitro and in vivo appraisal. AB - Attempting to prepare a convenient bioavailable formulation of vitamin B12 (cyanocobalamin), 17 tablet formulations were prepared by direct compression. Different concentrations of hydroxypropyl methyl cellulose (HPMC), carbopol 971p (CP971p), and chitosan (Cs) were used. The tablets were characterized for thickness, weight, drug content, hardness, friability, surface pH, in vitro drug release, and mucoadhesion. Kinetic analysis of the release data was conducted. Vitamin B12 bioavailability from the optimized formulations was studied on rabbits by the aid of enzyme-linked immunosorbent assay. Neurotone(r) I.M. injection was used for comparison. HPMC (F1-F4), CP971p (F5-F8), and HPMC/CP971p (F12-F15)-based formulations showed acceptable mechanical properties. The formulated tablets showed maximum swelling indices of 232 +/- 0.13. The surface pH values ranged from 5.3 +/- 0.03 to 6.6 +/- 0.02. Bioadhesive force ranged from 66 +/- 0.6 to 150 +/- 0.5 mN. Results showed that CP971p-based tablets had superior in vitro drug release, mechanical, and mucoadhesive properties. In vitro release date of selected formulations were fitted well to Peppas model. HPMC/CP971p-based formulations showed bioavailability up to 2.7-folds that of Neurotone(r) I.M. injection. PMID- 30289004 TI - Real-world treatment patterns of PCSK9 inhibitors among patients with dyslipidemia in Germany, Spain, and the United Kingdom. AB - OBJECTIVE: Proprotein convertase subtilisin/kexin type 9 antibody inhibitors (PCSK9i) are approved as adjuncts to maximal tolerated statin therapy to lower low-density lipoprotein cholesterol (LDL-C). This study describes real-world use, characteristics of PCSK9i users and non-users, and factors influencing treatment choice. METHODS: A physician and patient survey was conducted in Germany, Spain, and the UK from December 2016 to April 2017 through the Adelphi Dyslipidemia Disease Specific Program. Physicians reported patients' lipid-lowering therapy (LLT) history and characteristics. PCSK9i users were systematically over-sampled. Results were summarized using frequencies and proportions. RESULTS: The study included 110, 123, and 117 physicians from Germany, Spain, and the UK, respectively, providing data on 3,073 patients (mean age = 62 years; 60% male). Most patients (63-73%) had prior statin and/or ezetimibe use. Compared to patients receiving other LLT (n = 2686), PCSK9i users (222 in Germany, 97 in Spain, 68 in the UK) were, on average, 5-7.5 years younger and had LDL-C at diagnosis averaging 23-53 mg/dl higher. Familial hypercholesterolemia (FH), coronary heart/artery disease, myocardial infarction, and acute coronary syndrome were more common among PCSK9i users than non-users. PCSK9i users were also more likely to use high-intensity statins in their current LLT regimen (64-89% vs 28 50%). Physicians commonly reported PCSK9i benefits on LDL-C and total cholesterol as reasons for initiating these agents, and PCSK9i users reported good knowledge of cardiovascular disease and treatment options. CONCLUSIONS: Results indicate that physicians are prescribing PCSK9i to patients with high cardiovascular risk in accordance with European guidelines and reimbursement requirements. PMID- 30289006 TI - A Commercially Available Thermogenic Dietary Supplement Increases Resting Metabolic Rate in Physically Active Males: A Randomized, Double-Blind, Placebo Controlled Investigation. AB - Males seeking to improve body composition may ingest thermogenic dietary supplements with the goal of elevating resting metabolic rate. The purpose of this study was to examine the effects of a commercially available dietary supplement (containing ingredients that promote thermogenesis) on resting metabolic rate (RMR) in a randomized, double-blind, placebo-controlled cross-over study. Ten healthy, physically active males (age: 26.5 +/- 6.4 years; height: 177.6 +/- 7.2 cm; body weight: 80.5 +/- 10.8 kg) underwent two testing sessions separated by approximately 7 days. Following baseline assessments of RMR, heart rate (HR), and blood pressure (BP), each participant ingested a thermogenic dietary supplement or a placebo. Assessments were repeated at 60, 120, and 180 minutes postingestion. Approximately 1 week later, participants ingested the alternative supplement and the assessments were repeated. Post hoc analyses revealed that the dietary supplement treatment demonstrated significant elevations in RMR during the postingestion period (p < 0.05) from 1,859 +/- 266 kcal to 2,027 +/- 288 kcal (increase of 9%) to 2,072 +/- 292 kcal (increase of 11.5%) and to 2,040 +/- 271 kcal (increase of 9.7%) at 60, 120, and 180 minutes postingestion, respectfully. No significant elevations were observed in the placebo treatment at any time point. HR and BP measures were within normal clinical values throughout the intervention. PMID- 30289005 TI - Phase II Trial of Acai Juice Product in Biochemically Recurrent Prostate Cancer. AB - BACKGROUND: Plant derivatives have been studied as therapies for prostate cancer based on their purported anti-inflammatory and antioxidant properties and low toxicities. The acai berry is an example of a plant rich in phytochemicals, which may slow the growth of prostate cancer. METHODS: This was a phase II, Simon 2 stage clinical trial in patients with biochemically recurrent prostate cancer with a primary endpoint of prostate-specific antigen (PSA) response. Patients were asymptomatic, with a rising PSA of at least 0.2 ng/mL, and were treated with twice daily intake of Acai Juice Product until PSA progression, with a primary endpoint of PSA response. RESULTS: Twenty-one patients were enrolled in the first stage of the trial. One of those patients had a PSA response within the study time period. The PSA doubling time was lengthened in 71% of patients (95% confidence interval = 48% to 89%) on the trial, and in a small number of responders, this was sustained over an extended time. CONCLUSIONS: This study did not meet its primary endpoint of 50% PSA response. Nevertheless, the overall tolerability and effects on PSA stabilization warrant further exploration in a biochemically recurrent population. PMID- 30289007 TI - Visceral leishmaniasis elimination targets in India, strategies for preventing resurgence. AB - INTRODUCTION: Visceral leishmaniasis (VL) is a fatal parasitic disease caused by a parasite belonging to the Leishmania donovani complex and transmitted by infected female Phlebotomous argentipes sand flies. The VL elimination strategy in the Indian subcontinent (ISC), which has a current goal of reducing the incidence of VL to below 1/10,000 of population by the year 2020, consists of rapid detection and treatment of VL to reduce the number of human reservoirs as well as vector control using indoor residual spraying (IRS). However, as the incidence of VL declines toward the elimination goal, greater targeting of control methods will be required to ensure appropriate early action to prevent the resurgence of VL. Area covered: We discuss the current progress and challenges in the VL elimination program and strategies to be employed to ensure sustained elimination of VL. Expert commentary: The VL elimination initiative has saved many human lives; however, for VL elimination to become a reality in a sustained way, an intense effort is needed, as substantial numbers of endemic subdistricts (primary health centers (PHCs) blocks level) are yet to reach the elimination target. In addition to effective epidemiological surveillance, appropriate diagnostic and treatment services for VL at PHCs will be needed to ensure long-term sustainability and prevent reemergence of VL. PMID- 30289008 TI - Calendula officinalis: Potential Roles in Cancer Treatment and Palliative Care. AB - A continuous challenge in cancer management is to improve treatment efficacy and to diminish its side effects. Consequently, new conventional and unconventional drugs and bioactive compounds from plants are constantly developed, characterized, and used for in vitro and in vivo models. This review focuses on the antitumor properties of Calendula officinalis, its biological and molecular effects in tumor cells and animal models, as well as its role in cancer palliative care. A systematic review of studies describing the cytotoxic role of C officinalis and its therapeutic role on cancer cells were carried out using the PubMed database. Albeit C officinalis extracts have cytotoxic activity toward different cancer cell lines, a high grade of variation between studies was observed, depending on plant organ subjected to extraction, extraction method, and the cancer cell lines used for each study. Nevertheless, its cytotoxic activity is related to a few bioactive compounds, presenting multiple roles in both activation of proapoptotic proteins and decreasing the expression of the proteins that inhibit cell death. Moreover, due to its anti-genotoxic/protective as well as antitumor and antimetastatic effects proven in animal models, C officinalis could have important future implications in developing novel cancer treatment strategies, while until now it has been used especially for diminishing the side effects of radiotherapy. PMID- 30289009 TI - The economic burden of uncontrolled gout: how controlling gout reduces cost. AB - AIM: To evaluate the burden of uncontrolled gout by examining estimated costs and cost drivers. MATERIALS AND METHODS: Data from the 2012 and 2013 US National Health and Wellness Survey (NHWS; 2012 NHWS, n = 71,157 and 2013 NHWS, n = 75,000) were utilized in this study. Based on self-reported gout diagnosis and gout symptoms, respondents were categorized into three groups: controlled gout (n = 344), uncontrolled gout (n = 2,215), and non-gout controls (n = 126,360). Chi square tests and one-way analysis of variance (ANOVAs) were used to assess group differences on work productivity loss, healthcare resource utilization, and costs. Zero-inflated negative binomial regressions were used to assess the burden of uncontrolled gout on total costs after controlling for covariates. RESULTS: Patients with uncontrolled gout had higher presenteeism, overall work impairment, activity impairment, and number of emergency department visits than those with controlled gout or controls. Overall, uncontrolled gout patients had both higher indirect and total costs compared to patients with controlled gout. After controlling for confounders, those with uncontrolled gout had higher total costs than controlled gout respondents and non-gout controls; there was no significant difference in total costs between patients with controlled gout and non-gout controls. LIMITATIONS: Results were based on cross-sectional, self-reported data, making causal inferences more uncertain. Additionally, sample size was small for controlled-gout respondents. Lastly, sampling weights were not used, thus potentially limiting generalizability. CONCLUSION: Gout can be an expensive condition, particularly if it is not properly controlled. This study provides support that controlling symptoms (e.g. flares) can reduce the economic and societal burden of gout. Therefore, more attention needs to be paid to effective management of gout symptoms. PMID- 30289010 TI - Evaluating the cost-effectiveness of secukinumab in moderate-to-severe psoriasis: a Japanese perspective. AB - AIM: To evaluate the cost-effectiveness of secukinumab, a fully human anti interleukin-17A monoclonal antibody, compared to other clinically used biologics (adalimumab, infliximab, and ustekinumab) in Japan for the treatment of moderate to-severe psoriasis from the healthcare system (total costs) and patient co payment (using different frequencies of drug purchase) perspectives. METHODS: A decision-tree (first year)/Markov model (subsequent years), with an annual cycle, was developed. The model adopted a 5-year time horizon. Efficacy inputs were obtained from a mixed-treatment comparison analysis, and other model inputs were collected from published literature and local Japanese sources. Model outcomes included quality-adjusted life years (QALYs) and an incremental cost effectiveness ratio (ICER) in terms of cost per QALY gained. The annual discounting rate of 2% was applied to both costs and outcomes. RESULTS: Results for the healthcare system perspective showed that secukinumab had the highest number of quality-adjusted life years (QALYs) (4.07) vs other biologics, dominated ustekinumab and infliximab, and the ICER of secukinumab compared to adalimumab was Y8,418,222/QALY gained. In the patient co-payment perspective with the monthly purchase of drugs, ustekinumab had the lowest co-payment cost, followed by infliximab, adalimumab, and secukinumab. In the patient co-payment perspective with a once every 3 months purchase of secukinumab and adalimumab, the co-payment costs of secukinumab, adalimumab, and ustekinumab became comparable, and infliximab had the highest co-payment cost. LIMITATIONS: Only short-term efficacy data was modeled, as there was a lack of data on long-term outcomes. Treatment sequencing was restricted to first-line biologic treatment. Drop-out rates for comparators were assumed to be equivalent to secukinumab in the absence of available data. CONCLUSIONS: Secukinumab is a cost-efficient treatment for moderate-to-severe psoriasis, providing greater health outcomes to patients at lower total costs compared to infliximab and ustekinumab, as well as comparable patient co-payment relative to other biologic treatments. PMID- 30289011 TI - Quality Control Standardization and Evaluation of Antimicrobial Potential of Daruhaldi (Berberis aristata DC) Stem Bark. AB - Berberis aristata is used for the treatment of diabetes, piles, and liver diseases. As the drug is broadly used in Indigenous systems of medicine, it was designed to set the quality standards and antimicrobial potential for the stem bark of Berberis aristata. Botanical, physicochemical, pharmacotoxicological, fluorescence, microbial load, and phytochemical parameters of the stem bark were determined. High-performance thin-layer chromatography (HPTLC) was carried out by the CAMAG-HPTLC system. Berberine, total phenolics, and flavonoids were estimated. The antimicrobial potential was determined against the bacteria Bacillus subtilis and Escherichia coli and fungi Penicillium citrinum and Aspergillus terreus. The foreign matter, foaming index, swelling index, bitterness value, resin content, loss on drying, total ash, acid-insoluble ash, water-soluble ash, heavy metals, microbial load, berberine content, total phenolic content, and total flavonoid content were found to be 0, 0, 5, 1.34, 0.86%, 2.07%, 4.33%, 0.28%, 2.66%, within limits, 6 colonies in 1/100 dilution, 0.032 mg/g, 144.04 ug/ml, and 85.61 ug/ml, respectively. Phytochemicals such as phenolics, flavonoids, and sterols were present in the methanolic extract. The fluorescences observed in UV light were of different colors in different solvents. The methanolic extract and standards exhibited antimicrobial activity at the tested concentrations against the microbial strains. Results confirmed the quality and purity of the drug B. aristata. Results also confirmed that methanolic extract of B. aristata stem bark possesses potent antimicrobial activity. Thus, the use of this quality-controlled plant-derived drug with established antimicrobial property could be of great significance in quality control standardization and preventive and therapeutic approaches to infectious diseases. PMID- 30289012 TI - Genipin crosslinked curcumin loaded chitosan/montmorillonite K-10 (MMT) nanoparticles for controlled drug delivery applications. AB - Here, we have reported the influence of MMT and genipin in releasing curcumin from the Genipin crosslinked Chitosan/MMT nanoparticles, prepared by ionic gelation method. The nanoparticles were characterised using Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffractometry (XRD), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM). Zeta potential and average diameter of the nanoparticles were found in the range 32-47 mV and 430 560 nm. Swelling and release of curcumin from the nanoparticles increased with the decrease in pH of the medium, MMT, and genipin content. Curcumin released from the nanoparticles reduced the viability of MCF-7 and Hep G2 cells as compared to untreated cells. The nanoparticles increased the level of reduced glutathione (GSH), superoxide dismutase (SOD), and catalase level in human PBMCs and decreased the level of Lipid peroxidation suggesting an enhanced protection against cellular damage. Lower pH and higher MMT concentration in the nanoparticles improved the mucoadhesive properties. PMID- 30289013 TI - Clinicopathological characteristics and renal outcomes of childhood-onset lupus nephritis with acute kidney injury: a multicenter study. AB - OBJECTIVES: Acute kidney injury (AKI) at onset of adult systemic lupus erythematosus (SLE) is a risk factor for end stage kidney disease (ESKD). However, data on childhood-onset lupus nephritis (LN) with AKI are scarce. METHODS: We retrospectively reviewed the complete files of pediatric SLE patients from 1995 to 2010. All patients underwent kidney biopsy promptly after diagnosis. RESULTS: Thirty-six patients (10 males and 26 females) were enrolled. Mean age at diagnosis and observation period were 11.6 +/- 2.4 years and 8.1 +/- 4.4 years, respectively. Seven patients had AKI at onset of SLE. Compared with those without AKI, patients with AKI had significantly higher proportions of pathologically proliferative LN. Only one patient with AKI progressed to ESKD without complete recovery of renal function. Overall and renal survival rates were 100% and 97.2%, respectively. There was no significant difference in estimated glomerular filtration rate at the final visit (85.0 ml/min/1.73 m2 in the AKI group vs. 103.2 ml/min/1.73 m2 in the non-AKI group; p = 0.11). CONCLUSIONS: Our study demonstrated favorable renal outcomes in childhood-onset LN with AKI in the near to midterm period. Inducing complete remission may be important for preserving renal function. PMID- 30289014 TI - Pharmacokinetics of mycophenolate mofetil in juvenile patients with autoimmune diseases. AB - OBJECTIVES: This study aimed to determine the association between the dosage and pharmacokinetics of mycophenolate mofetil (MMF) in juvenile patients with autoimmune diseases. METHODS: Totally, 29 patients were administered oral MMF. The blood concentrations of mycophenolate acid (MPA) at seven points, the area under the time-concentration curve (MPA-AUC0-12h), the peak concentration (Cmax), and the time to peak concentration (Tmax) were measured. To obtain a dose normalized MPA-AUC0-12h value, the actual measured MPA-AUC0-12h value was divided by the dose value of the morning administration corrected for body weight (BW) or body surface area (BSA). The patients were classified into three age groups (group 1, <=10 years; group 2, >10-<=15 years; and group 3, >15 years), and pharmacokinetic parameters were compared among the groups. RESULTS: In total, we obtained 37 measurements. The actual measured MPA-AUC0-12h values and the MPA AUC0-12h values corrected for dose per BW and Tmax were lower in young patients. The MPA-AUC0-12h values corrected for dose per BSA and Cmax were comparable among all the groups. CONCLUSIONS: In patients with juvenile autoimmune diseases, determining MMF administration dosage according to BSA may facilitate MPA-AUC0 12h value prediction. PMID- 30289015 TI - Cold hypersensitivity after hand injuries. A prospective 7-year follow-up. AB - We studied changes in cold hypersensitivity from 3 to 7 years following severe hand injuries. Data was collected using postal questionnaires 7 years after injury in 71 patients who had participated in a 3-year follow-up from the time of injury. There was no change in cold sensitivity measured using the McCabe Cold Sensitivity Severity scale (CSS) from 3 to 7 years after injury. However, there was a trend toward decreased severity measured using a five-level scale of self reported cold hypersensitivity. Compared to the 3-year follow-up, fewer respondents rated their condition as severe and two patients had recovered from their cold hypersensitivity at the 7-year follow-up. Furthermore, 21 (30%) of the respondents stated a decrease in cold hypersensitivity during the last 2 years. Limitations in cold associated activities and the importance of being less limited in leisure activities (NRS 0-10) did not change between the two follow ups. In conclusion, the CSS-scores did not change from 3 to 7 years after injury. Several patients experienced improvements in cold hypersensitivity, but few recovered completely from the condition. PMID- 30289016 TI - A new screening tool for self-neglect in community-dwelling older adults: IMSelf neglect questionnaire. AB - OBJECTIVE: We aimed to develop a new screening tool for self-neglect in community dwelling self-sufficient older adults. METHODS: Istanbul Medical School Elder Self-Neglect questionnaire (IMSelf-neglect) was developed as a screening tool. Community-dwelling, self-sufficient older adults were recruited in a geriatric outpatient clinic (n = 226, 142 female, 84 male). Construct validity was based on social-worker's interview as a gold-standard method. The cut-off threshold for IMSelf-neglect questionnaire was calculated from ROC-analysis using cut-off values that predicted social-worker's opinion whether the older adult has self neglect. RESULTS: Mean age was 74 +/- 6.5 years. The inter-rater and test-retest reliability were excellent (r = 0.887, p < .05; r = 0.942, p < .05, respectively). The internal consistency was good (Cronbach's alpha: 0.708). Cut off threshold for IM Self-neglect questionnaire was calculated as 7 with 92.1% sensitivity and 70.7% specificity. Positive predictive value and negative predictive value of IMSelf-neglect questionnaire were 38.9% and 97.8%, respectively. There was significant moderate agreement between social worker's assessment and results of IMSelf-neglect questionnaire (kappa = 0.407, p < .001). The social worker confirmed 16.8% of the participants have self-neglect by the gold-standard clinical interview. Participants with self-neglect had decreased functionality, worse quality of life and tended to have more depression compared with participants without self-neglect. DISCUSSION/CONCLUSION: We developed the IMSelf-neglect questionnaire as a valid and reliable tool to screen self-neglect in outpatient clinics complementary to comprehensive geriatric assessment. PMID- 30289017 TI - Anti-vasospastic effects of botulinum toxin B pretreatment in animal models. AB - BACKGROUND: Botulinum toxin has been recently known for its vasodilatory effect. The main purpose of our study was to demonstrate the anti-vasospastic effect of botulinum toxin B in animal models. METHOD: In this prospective experimental rat study, we used 10 male Sprague-Dawley rats. The right and left inguinal areas (femoral vessels) served as the experimental and control groups, respectively. Three days prior to the experimental procedure, botulinum toxin B and normal saline were subcutaneously injected in the experimental and control groups, respectively. After three days, the vascular diameter and flow were measured. Then, phenylephrine was injected, and after one hour the same parameters were measured. RESULTS: The changes in arterial diameter in the experimental and control group were 30.83 +/- 10.43% and 40.00 +/- 8.61%, respectively. The vein diameter decreased by 22.98 +/- 10.08% in the experimental group compared to 49.05 +/- 10.08% for the control group. Furthermore, the arterial flow change in the control group was 8.28 +/- 2.10% compared to 1.16 +/- 0.65% in the experimental group. In addition, the venous flow in the control group decreased by 9.27 +/- 2.75% compared to 0.92 +/- 0.56% in the experimental group. Both arterial and venous diameters and flows showed statistical significance between the experimental and control groups (p < .05). CONCLUSIONS: Our study demonstrated that pretreatment with botulinum toxin B led to significantly reduced change in vascular diameters and flows compared with the control group, supporting the anti-vasospastic effects of botulinum toxin B. PMID- 30289018 TI - The findings of musculoskeletal ultrasonography on primary Sjogren's syndrome patients in childhood with articular manifestations and the impact of anti-cyclic citrullinated peptide antibody. AB - OBJECTIVE: We researched the findings of musculoskeletal ultrasound sonography (MSUS) on primary Sjogren's syndrome in childhood (pSS-C) with articular manifestations. The correlation of rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibody (ACPA) were investigated to evaluate the usefulness of MSUS on their articular prognosis. METHOD: The objective patients are pSS-C cases who visited our hospital complaining joint pain and/or joint swelling and for whom MSUS was performed. RESULT: Eight patients included 6 female and 2 male, 5 RF-positive patients and 3 ACPA- positive patients. The mean age of onset was 11.1+/-3.0 years (352 physical joint findings and 284 MSUS findings The number of joints found clinical articular manifestations was 58/352 joints, and arthritis detected by MSUS was 30/284 joints). In multivariate analysis, odds ratio of clinical articular manifestations was significant high in RF-positivity (2.9, 95%CI 1.5-6.2). Odds ratio of arthritis detected by MSUS in ACPA-positivity was significant high (3.7, 95%CI 1.5-11.6), although odds ratio in RF-positivity had no statistical significance. And a similar trend was seen in odds ratios of subclinical arthritis (4.9, 95%CI 1.6-18.0). CONCLUSION: It was indicated that MSUS is useful for pSS-C. ACPA-positive pSS-C patients have arthritis and subclinical arthritis more frequently than ACPA-negative patients. PMID- 30289019 TI - Cafeteria diet during lactation and/or post-lactation altered lipid profile/lipid peroxidation and increased anxiety-like behavior in male rat offspring. AB - OBJECTIVE: Evaluate the impact of the cafeteria diet during lactation and/or post lactation on physiological parameters and anxiety in the offspring of Wistar rats. METHODS: Male offspring of Wistar rats (n = 60) were randomized into four groups: Control (C), Lactation Cafeteria (LC), Post-lactation Cafeteria (PC) and Total Cafeteria (TC). Later in adult life the animals were submitted to the behavioral (elevated plus-maze and open field) and biological (body weight, consumption and food preference, glycemia, total cholesterol, LDL cholesterol, HDL cholesterol, VLDL cholesterol, triglycerides, total proteins, urea, creatinine, bilirubin, serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, serum protein, and oxidative stress) evaluations. The data were submitted to ANOVA, followed by the Newman-Keuls test (p < 0.05). RESULTS: Animals treated with the cafeteria diet presented greater weight measurements compared to the control group. Triglyceride levels were higher in the PC group than in the other groups. MDA levels were higher in the PC and TC group than CL and C. The animals of the PC and TC groups presented higher levels of anxiety compared to the C and LC groups. No significant differences due to diet were observed in the locomotor and exploratory behaviors. CONCLUSIONS: The cafeteria diet ingestion was capable of triggering biological and behavioral alterations in rats. PMID- 30289021 TI - Semiparametric Bayesian kernel survival model for evaluating pathway effects. AB - Massive amounts of high-dimensional data have been accumulated over the past two decades, which has cultured increasing interests in identifying gene pathways related to certain biological processes. In particular, since pathway-based analysis has the ability to detect subtle changes of differentially expressed genes that could be missed when using gene-based analysis, detecting the gene pathways that regulate certain diseases can provide new strategies for medical procedures and new targets for drug discovery. Limited work has been carried out, primarily in regression settings, to study the effects of pathways on survival outcomes. Motivated by a breast cancer gene-pathway data set, which exhibits the "small n, large p" characteristics, we propose a semiparametric Bayesian kernel survival model (s-BKSurv) to study the effects of both clinical covariates and gene expression levels within a pathway on survival time. We model the unknown high-dimensional functions of pathways via Gaussian kernel machine to consider the possibility that genes within the same pathway interact with each other. To address the multiple comparisons problem under a full Bayesian setting, we propose a similarity-dependent procedure based on Bayes factor to control the family-wise error rate. We demonstrate the outperformance of our approach under various simulation settings and pathways data. PMID- 30289020 TI - The Self-Assessed Bekesy Procedure: Validation of a Method to Measure Intelligibility of Connected Discourse. AB - In clinical practice and research, speech intelligibility is generally measured by instructing the participant to recall sentences. Although this is a reliable and highly repeatable measure, it cannot be used to measure intelligibility of connected discourse. Therefore, we developed a new method, the self-assessed Bekesy procedure, which is an adaptive procedure that uses intelligibility ratings to converge to a person's speech reception threshold. In this study, we describe the new procedure and the validation in young, normal-hearing listeners. First, we compared the results on the self-assessed Bekesy procedure to a recall procedure for standardized sentences. Next, we evaluated the inter- and intrasubject variability of our procedure. Furthermore, we compared the thresholds for sentences in three masker types between the self-assessed Bekesy and a recall procedure to verify if these procedures resulted in similar conclusions. Finally, we compared the thresholds for two types of sentences and commercial recordings of stories. In general, the self-assessed Bekesy procedure is shown to be a valid and reliable procedure as similar thresholds (difference < 1 dB) and test-retest reliability (< 1.5 dB) were observed compared with standard speech audiometry tests. In addition, the time efficiency and similar differences between maskers to a recall procedure support the potential of this procedure to be implemented in research. Finally, significant differences between the thresholds of sentences and connected discourse materials were found, indicating the importance of controlling for differences in intelligibility when presenting these materials at the same signal-to-noise ratios or when comparing studies. PMID- 30289022 TI - Giving Back Is Receiving: The Role of Generativity in Successful Aging Among HIV Positive Older Adults. AB - OBJECTIVES: Successful aging has been identified as an important emphasis for people living with human immunodeficiency virus (HIV). Little is known about how this population conceptualizes aging successfully and how this relates to generativity. This qualitative study examined the importance of generativity among 30 HIV-positive older adults to determine the role of generativity in successful aging. METHOD: Participants aged 50+ years were recruited in Ontario, Canada, through acquired immunodeficiency syndrome (AIDS) service organizations, clinics, and community agencies. Qualitative interviews were analyzed to explore strategies participants employed to engage in successful aging within their own personal context. RESULTS: Participants saw themselves as pioneers and mentors, helping others to navigate the landscape of aging with HIV. Four themes were identified through consensus including (a) reciprocity, (b) mentoring, (c) pioneerism, and (d) connecting through volunteerism. DISCUSSION: Interventions that promote intergenerational connections, community involvement, and generative acts within the HIV community can facilitate successful aging among older adults living with HIV/AIDS. PMID- 30289023 TI - Narrating ethnicity and diversity in Middle Eastern national genome projects. AB - Most Middle Eastern populations outside Israel have not been represented in Western-based international human genome sequencing efforts. In response, national-level projects have emerged throughout the Middle East to decode the Arab, Turkish and Iranian genomes. The discourses surrounding the 'national genome' that shape scientists' representation of their work to local and international audiences evoke three intersecting analytics of nationalism: methodological, postcolonial and diasporic. Methodologically, ongoing human genome projects in Turkey and Iran follow the population logics of other national and international genome projects, for example justifying research with reference to projected health benefits to their fellow citizens. Meanwhile, assumptions about and representations of ethnicity and diversity are deeply inflected by local histories of scientific development and nationalist politics. While Iranian geneticists have transformed this paradigm to catalog national genetic diversity through a discourse of 'Iranian ethnicities', Turkish geneticists remain politically constrained from acknowledging ethnic diversity and struggle to distance their work from racialized narratives of Turkish national identity. Such nationally-framed narratives of genomic diversity are not confined to their original contexts, but travel abroad, as demonstrated by a US-based genome project that articulates a form of Iranian-American diasporic nationalism.

AB - The 1994 Rwandan genocide was characterized by brutal acts of widespread sexual violence against women that, for some, led to unwanted pregnancy, childbirth, and motherhood. This study explores the perspectives and experiences of 44 Rwandan women with children born of genocidal rape through in-depth qualitative interviews. Emerging from the data are the themes of identity and belonging, ambivalence, and truth-telling in the mother-child relationship. Findings highlight the lasting and intergenerational legacy of genocidal rape, and practice and policy implications are discussed. PMID- 30289025 TI - Determining energy requirement and evaluating energy expenditure in neurological diseases. AB - OBJECTIVES: It has been reported that in most neurological patients, resting energy expenditure due to hypermetabolism is increased. Physical activity, which is another component of energy expenditure, varies depending on the course of the disease. Different mechanisms are used to explain changes in energy expenditure in this population. Pathological problems of centers that regulate energy balance in the brain, endocrine and metabolic dysfunction, mitochondrial damage, autonomic dysfunction and inflammatory anomalies are thought to be at the root of this situation. In this review study, studies about energy expenditure and energy requirement in neurological diseases have been examined and suggested practices in this field have been presented. METHODS: We reviewed articles regarding selected from PubMed, Science Direct, EBSCO, and databases about energy expenditure and neurological diseases. RESULTS: Based on the type of neurological diseases; factors such as stage of the disease, disease complications, metabolic status, mechanical ventilation, body composition, movement restrictions or hyperactivity change energy expenditure and, as a result, nutrition requirement. Determination of the energy requirement is the basic variable for adjusting medical nutrition therapy. Despite an increase in resting energy expenditure as a result of metabolic processes in most neurological disorders, the daily energy expenditure is reported to change based on the restriction of physical activity due to the disorder. DISCUSSION: Determining patient's energy expenditure and energy requirements is regarded as the right approach in terms of improving the patient's quality of life, regulating appropriate medical nutrition treatment and increasing the effectiveness of other treatments. PMID- 30289026 TI - The pharmacodynamic profile of "Blackadder" blackcurrant juice effects upon the monoamine axis in humans: A randomised controlled trial. AB - Emerging evidence from human intervention trials indicates health benefits of consuming blackcurrant fruit, including improvements to cognitive performance, modulation of blood flow, regulation of blood glucose and inhibition of enzymes underpinning normal cognitive function. Of particular relevance is our previous demonstration of monoamine oxidase (MAO)-A and B inhibition after the consumption of a New Zealand "Blackadder" blackcurrant juice in humans. The current study uses a double-blind, placebo-controlled, randomised cross- over design to assess the pharmacodynamics of the effects on platelet MAO-B inhibition and associated substrates, plasma prolactin levels and blood glucose levels after consumption of a single serve of "Blackadder" blackcurrant juice standardised to 500 mg polyphenols. Eight healthy male (20--35 years) participants completed the trial. Measurements were obtained at baseline 15, 30, 45, 60, 100, 120, 150, 180, 240 mins and 24 h post dose. A fast, absolute and reversible inhibition of blood platelet MAO-B (P < 0.001) and a significant but delayed reduction in plasma prolactin (P < 0.001) were observed following the consumption of "Blackadder" blackcurrant juice when compared to a placebo control. No interpretable changes in substrates of MAO or associated metabolites were seen. These data provide a clear time course of the reversible inhibition of MAO-B after the single consumption of a of New Zealand "Blackadder" blackcurrant juice standardised at 500 mg of polyphenols and, therefore, provide a therapeutic window on which to base future nutritional interventions. PMID- 30289027 TI - On mountains and prophets: targeting majorities to support minorities by using norm-critics in health education. AB - This debate article advocates for norm-critics instead of empowering coping and pedagogy of tolerance as an educational approach to mitigate stigmatization as well as blame and guilt for health-deviant minorities within the field of health disparities. Norm-critics is a way of making members of the (presumably healthy) normative majority uncover and question their health-related norms and raise awareness for the processes by which members of that majority re/construct images of stereotypic figures (such as "the fatso" or "the couch-potato") with certain personal character traits which are to be condemned and, in doing so, limit the acting space of those identified as examples of those figures. The approach, its theoretical background, arguments promoting norm-critics, and some suggestions for its practical application are presented. It is concluded that norm-critics render a valuable and much needed addition to the health intervention repertoire. PMID- 30289028 TI - Do mental health patients learn what their cognitive-behaviour therapists think they do? A short report on qualitative interviews comparing perspectives. AB - PURPOSE: The acquisition of skills is essential to the conceptualization of cognitive-behavioural therapy. Yet, what experiences are encountered and what skills actually learned during therapy, and whether patients and therapists have concurrent views hereof, remains poorly understood. METHOD: An explorative pilot study with semi-structured, corresponding interview guides was conducted. Pilot data from our outpatient unit were transcribed and content-analyzed following current guidelines. RESULTS: The responses of 18 participants (patients and their psychotherapists) were assigned to six main categories. Educational and cognitive aspects were mentioned most frequently and consistently by both groups. Having learned Behavioural alternatives attained the second highest agreement between perspectives. CONCLUSIONS: Patients and therapists valued CBT as an opportunity to learn new skills, which is an important prerequisite also for the maintenance of therapeutic change. We discuss limitations to generalizability but also theoretical and therapy implications. PMID- 30289029 TI - Parents' experiences with sleep problems in children aged 1-3 years: a qualitative study from a health promotion perspective. AB - PURPOSE: The aim of this study was to explore the experiences of parents whose children aged 1-3 years have sleep problems, from a health promotion perspective. METHODS: This was a qualitative study, based on semi-structured interviews with 12 mothers in Norway. The material was analysed by qualitative content analysis. RESULTS: Parents experienced problems with getting their children to bed, getting them to fall asleep, and episodes of awakening at night. Parents expressed that it was time-consuming and difficult to teach their children sleep regulation. Parents handled the sleep problems through the following coping strategies: acknowledging challenges, clarifying one's self-understanding, implementing change measures, and safeguarding family well-being. These coping strategies resulted in this main theme: the health-promoting regulation of interactions, including parents' strengthening of sleep regulation in their small children and the safeguarding of well-being in the family. CONCLUSIONS: Early, individually customized guidance for parents, with a focus on revealing and acknowledging their experiences with sleep problems in children, is essential for parents to find opportunities to cope with such challenges. Appropriate goals seem to be important for them to succeed in strengthening sleep regulation in their children in a more satisfactory way. PMID- 30289030 TI - Energy flux: staying in energy balance at a high level is necessary to prevent weight gain for most people. AB - Energy flux, the rate of energy conversion from absorption to expenditure or storage, is a critical component of understanding weight management. Individuals who maintain body weight over time have common characteristics including a relatively high level of physical activity and minimal changes in body composition, muscle mass and metabolic rate. A higher state of energy flux resulting from high energy expenditure may provide for a greater 'sensitivity' between energy intake and expenditure. This sensitivity stabilizes body weight by enhancing reciprocal compensation among these components with changes in eating or activity. The energy balance framework suggests that a higher level of energy expenditure requires higher energy intake to maintain body mass. Maintaining energy balance at a higher caloric intake and expenditure should be a more successful long-term strategy for weight maintenance than reduced consumption or extreme caloric restriction at a low level of energy expenditure (a low energy flux) and improve intervention effectiveness for sustainable methods for body weight stability. PMID- 30289031 TI - The impact of fibroblast growth factor-23 on the cardiovascular system in chronic kidney disease. AB - Chronic kidney disease is associated with an accelerated risk of cardiovascular (CV) mortality. Seminal work over the last decade has identified abnormal bone metabolism as an important modulator of the increased CV burden in this cohort. In particular, FGF23, a phosphaturic hormone with serum levels found to be markedly elevated in chronic kidney disease, is independently associated with increased risks of all-cause mortality and CV events. This editorial will discuss the proposed mechanisms linking FGF23 to CV disease in chronic kidney disease, namely, direct cardiac myocyte toxicity, endothelial dysfunction and vascular calcification. PMID- 30289032 TI - Relevance, pathogenesis and clinical implications of thyroid disorders in children with celiac disease. AB - Celiac disease is a frequent chronic inflammatory small bowel disease which may present itself with associated autoimmune comorbidities. Among these comorbidities, thyroid disorders show a significant prevalence; even in the pediatric population. However, the exact epidemiology and clinical significance of such alterations are yet to be fully elucidated. The most updated guidelines do not currently offer any specific support. Focusing on the pediatric population, we will review the recent available literature that we believe might be helpful in advancing the clinician's knowledge-base regarding this issue. We also discuss which, to our knowledge, are the key pathophysiologic concepts behind the association between these two entities. Finally, we offer our own clinical perspective, recommending routine laboratory thyroid screening, possibly followed by an echographic thyroid evaluation as we believe such an approach to be appropriate when caring for children with celiac disease. PMID- 30289033 TI - Elosulfase alfa for the treatment of mucopolysacchoridosis IVA. AB - Mucopolysacchariodosis IVA is a lysosomal storage disorder characterized by deficiency of the enzyme N-acetylgalactosamine-6-sulfatase leading to accumulation of glycosaminoglycans. Mucopolysacchariodosis IVA affects many organs, especially the skeletal system. The disease is progressive, leads to serious cardiopulmonary problems and is severely debilitating. Enzyme replacement therapy with elosulfase alfa is the only approved treatment for this rare genetic condition. The results from a Phase III clinical trial demonstrated that elosulfase alfa at dose 2.0 mg/kg weekly given intravenously improved the walking distance in 6 min. The results of the 3-min stair climb test and respiratory function test did not show statistically significant improvement over the placebo. However, the composite end point analysis combining changes from baseline in walking distance in 6 min, 3-min stair climb test and respiratory function showed that at dose 2.0 mg/kg weekly, subjects performed better than the placebo, indicating that the effects of treatment are clinically meaningful. Serious side effects are uncommon and infusion-associated reactions are manageable. PMID- 30289034 TI - Dulaglutide, a GLP-1 receptor agonist, for the treatment of type 2 diabetes. AB - The prevalence of diabetes continues to rise worldwide. Over the past five years, available treatment options have expanded to allow individualized management of patients with diabetes. The glucagon-like peptide-1 (GLP-1) receptor agonists have become an essential tool in the management of type 2 diabetes mellitus (T2DM). This class provides several advantages for glycemic control with minimal risk of hypoglycemia. Based on the most recent guidelines for T2DM, GLP-1 receptor agonists can be prescribed as monotherapy or in combination with oral antidiabetic agents or insulin for the management of T2DM. Dulaglutide has become the most recent and available GLP-1 receptor agonist on the market. Dulaglutide is a once-weekly GLP-1 receptor agonist that can be used as monotherapy or as a second-line agent for T2DM. This review article summarizes the efficacy, safety, and clinical attributes of dulaglutide among patients with T2DM. PMID- 30289035 TI - Sodium-glucose co-transporter 2 inhibitors: evidence and place in therapy. AB - Type 2 diabetes effects millions of people yet remains difficult to treat with oral pharmacotherapy. Metformin is the first line recommended therapy, and current guidelines suggest individualized therapy for second line selection. Sodium-glucose co-transporter 2 (SGLT-2) inhibitors are the newest class of agents in treating type 2 diabetes via an insulin independent mechanism to lower blood glucose. Currently marketed agents, including canagliflozin, dapagliflozin, empagliflozin, and luseogliflozin, reduce hemoglobin A1c (HbA1c) ~0.8-1%, reduce fasting and post prandial glucose, and have little hypoglycemia associated with them when added to therapies including metformin, a sulfonylurea, pioglitazone, or insulin. Patients receiving SGLT-2 inhibitors have reduced weight and blood pressure, but are more susceptible to urinary tract infections and genital mycotic infections. This review summarizes current literature regarding the SGLT 2 inhibitors. PMID- 30289036 TI - Effects of anti-diabetic drugs on bone metabolism. AB - An increased fracture risk is observed in Type 1 and Type 2 diabetic patients. Although diabetes-related complications are important in the etiology of bone fracture in diabetes, the effect of anti-diabetic medications should not be neglected. Indeed, many drugs used commonly to treat diabetes can interfere with bone physiology, resulting in a positive or negative impact on skeletal health. The aim of the present review is to summarize the current evidence on the effects of anti-diabetic drugs on bone. PMID- 30289037 TI - Diagnosis, treatment and clinical perspectives of acromegaly. AB - Acromegaly is an insidious disease of the pituitary caused by a growth hormone secreting adenoma. Generally, the diagnosis is made rather late in the course of the disease. Currently, acromegaly can be cured in about half of the patients with the disease by expert surgery. The remainder of non-surgically cured patients often can be effectively treated with somatostatin analogs; either with the new generation of dopaminergic drugs or with Pegvisomant, a GH-receptor blocking agent. However, at the time of diagnosis many patients suffer from serious comorbidities, including hypertension, heart disease, arthrosis, sleep apnea and diabetes mellitus. Recent reports have shown that mortality risk can be normalized. Nevertheless, all efforts should be undertaken to treat comorbidities. New strategies for surgery and medical treatment are discussed. PMID- 30289038 TI - Precocious pubertal development: a challenge for pediatric endocrinologists. AB - Precocious puberty is one of the most common conditions encountered in the pediatric endocrinology clinic and can be defined as the appearance of secondary sexual characteristics in girls under 8 years and boys under 9 years of age. The timing of pubertal onset has received increasing attention because of a reported gradual decline in age at menarche in most populations. Proposed mechanisms for these changes include: an improvement in socioeconomic conditions with consequent increased nutritional status and a rise in a number of environmental pollutants. The challenges for pediatric endocrinologists are increasing: what are the mechanisms of precocious puberty in modern society? Should our diagnostic criteria be changed? When to treat? What are the consequences of treatment? Little is known of the short and long term consequences of GnRH-analog treatment, especially in terms of psychological consequences for children and their families. PMID- 30289039 TI - Recommendations for hormone therapy in hysterectomized women: importance of new data in clinical management. AB - Women with a prior hysterectomy with and without oophorectomy represent special cohorts among those who require menopausal hormone therapy (HT), as a progestogen is not required for endometrial protection. This is relevant in light of recent research demonstrating superiority of estrogen therapy alone compared with estrogen plus a progestogen with respect to breast cancer risk and perhaps even cardiovascular protection. No longer is it appropriate to lump all HT regimens together when advising patients. Unfortunately, there is a general reluctance in the healthcare community to prescribe HT even a decade after publication of the results of the Women's Health Initiative trial. However, with subsequent research showing a favorable benefit/risk balance of short-term estrogen therapy in symptomatic, recently menopausal women, especially those who have undergone hysterectomy with oophorectomy, the need for educating patients and providers on the matter cannot be overemphasized. PMID- 30289040 TI - Science of premix insulin: where have we reached? AB - Diabetes is a progressive disease and by achieving and maintaining optimal glycemic control, the onset of complications can be prevented or delayed. Insulin is most effective at any stage of diabetes. Although basal-bolus therapy is the gold standard treatment, it has its own limitations such as multiple pricks, close monitoring and cost. Premixed insulin on the other hand is convenient, requires fewer injections, is a single device and delivers both the basal and bolus component till the next meal. Although premixed insulin analogs have the advantages of mealtime flexibility, compliance and better post-prandial glucose control, no significant differences have been observed in HbA1c reduction and overall hypoglycemia when compared to premixed human insulin. This review will attempt to analyze the efficacy, safety and limitations of currently available premix human insulin and premix analogs including recent advancements in the area. PMID- 30289041 TI - Heterogeneity in diabetes-associated autoantibodies and susceptibility to Type 1 diabetes: lessons for disease prevention. AB - Autoantibodies against pancreatic islets are strong predictors of Type 1 diabetes. When persistent beta-cell autoantibodies against at least two autoantigens are detected, the probability of diabetes is extremely high, although the time period before disease development can vary from days up to more than 20 years. Insulin autoantibodies or antibodies specific to glutamate decarboxylase 65 enzyme are in most cases, the first autoantibodies to appear. Insulin autoantibodies typically emerge very early with a peak at the age of 1.5 years, whereas the onset of glutamic acid decarboxylase 65 antibody positivity has a more even distribution, peaking later in childhood. These differences in the timing of appearance suggest that different environmental factors might be involved in the initiation of beta-cell autoimmunity beginning either already in infancy or later on. This should be taken into account in studies aimed at identifying environmental factors triggering islet cell-specific autoimmunity and also in the design of prevention trials. PMID- 30289042 TI - The non-glycemic effects of incretin therapies on cardiovascular outcomes, cognitive function and bone health. AB - The incretin therapies, glucagon-like peptide-1 receptor agonists and dipeptidyl peptidase-4 inhibitors, have been developed to lower blood glucose levels in patients with Type 2 diabetes. However, in addition to being a treatment strategy to improve metabolic control, incretin therapies have shown effects independent of glycemic control, including the potential to positively impact cardiovascular events, cognitive deficits and bone mineral density. This paper outlines the non glycemic effects of incretin therapies on cardiovascular disease, cognitive function and bone health. PMID- 30289043 TI - Future challenges for pediatric diabetes management in developing countries: lessons from Africa. AB - In this review, we describe the epidemiology of diabetes mellitus in children and adolescents in Africa, noting that there is a paucity of data with regard to the burden of disease, prevalence of undiagnosed diabetes, healthcare and acute and chronic complications. Furthermore, access to care remains an issue of great concern. Our view is that in the next 5 years, more research will be undertaken on the burden of the disease and on interventions to provide better access to care. While the majority of African countries still have a low incidence of diabetes in children, it is predicted that the incidence will increase and it is therefore essential that governments develop sustainable policies to deal with such increases. PMID- 30289044 TI - Luteinizing hormone and human chorionic gonadotropin: a review of their varied clinical applications in assisted reproductive technology. AB - Luteinizing hormone (LH) and human chorionic gonadotropin (hCG) are often viewed as interchangeable from a functional standpoint because they are highly homologous members of the same glycoprotein hormone family that share a common alpha-subunit and receptor. However, technological advances yielding highly purified and recombinant gonadotropin preparations have revealed that LH and hCG fulfill different roles, both endogenously and when administered exogenously. These differences are becoming more apparent as the individual hormones are incorporated into the treatment of infertility - a therapeutic area that is continually advancing with the introduction of new agents and emerging clinical trial data. This review examines the unique attributes of LH and hCG that drive their distinctive applications in the treatment of female infertility. PMID- 30289045 TI - Insulin, carbohydrate restriction, metabolic syndrome and cancer. AB - We propose that dietary carbohydrate restriction, particularly ketogenic diets, may provide benefit as a therapeutic or preventive strategy in cancer, alone or as an adjunct to pharmacology. The argument derives from several points of evidence: There is a close association between cancer and both diabetes and obesity. Extensive evidence shows that low carbohydrate diets are the most effective dietary treatment of Type 2 diabetes and dietary adjunct in Type 1. Such diets also target all the markers of metabolic syndrome. Finally, de facto reduction in carbohydrate likely contributes to total dietary restriction, which is effective in the prevention and treatment of cancer. The idea is consistent with recent interest in treating cancer with drugs that target diabetes. To move forward, we must understand obesity and diabetes as response to a hyperglycemic state rather than simply a cause of downstream effects. PMID- 30289046 TI - Applying emerging science to contraception research: implications for the clinic. AB - Emerging science will make an important contribution towards the development of improved contraceptives. While long-acting reversible contraceptives remain the most effective method, new user-controlled, mid-acting methods will avoid the need for procedures requiring trained providers. Contraceptives combined with other agents may bring additional health benefits, such as dual protection against both pregnancy and sexually transmitted infections. Emerging research areas in proteomics allowed the discovery of new reproductive targets that may lead to non-hormonal contraceptives for both men and women. Current research objectives include the improvement of existing contraceptive methods, as well as discovery of new materials able to deliver new molecules more specifically to their target without systemic actions. PMID- 30289047 TI - Molecular genetic advances in pituitary tumor development. AB - Pituitary adenomas are a heterogeneous group of tumors that may occur as part of a complex syndrome or as an isolated endocrinopathy and both forms can be familial or non-familial. Studies of syndromic and non-syndromic pituitary adenomas have yielded important insights about the molecular mechanisms underlying tumorigenesis. Thus, syndromic forms, including multiple endocrine neoplasia type 1 (MEN1), MEN4, Carney Complex and McCune Albright syndrome, have been shown to be due to mutations of the tumor-suppressor protein menin, a cyclin dependent kinase inhibitor (p27Kip1), the protein kinase A regulatory subunit 1 alpha, and the G-protein alpha-stimulatory subunit (Gsalpha), respectively. Non syndromic forms, which include familial isolated pituitary adenoma (FIPA) and sporadic tumors, have been shown to be due to abnormalities of: the aryl hydrocarbon receptor-interacting protein; Gsalpha; signal transducers; cell cycle regulators; transcriptional modulators and miRNAs. The roles of these molecular abnormalities and epigenetic mechanisms in pituitary tumorigenesis, and their therapeutic implications are reviewed. PMID- 30289048 TI - Implementing a low-carbohydrate, ketogenic diet to manage type 2 diabetes mellitus. AB - INTRODUCTION: Type 2 diabetes mellitus (T2DM) has reached epidemic proportions in the modern world. For individuals affected by obesity-related T2DM, clinical studies have shown that carbohydrate restriction and weight loss can improve hyperglycemia, obesity, and T2DM. Areas covered: Reducing carbohydrate intake to a certain level, typically below 50 g per day, leads to increased ketogenesis in order to provide fuel for the body. Such low-carbohydrate, ketogenic diets were employed to treat obesity and diabetes in the 19th and early 20th centuries. Recent clinical research has reinvigorated the use of the ketogenic diet for individuals with obesity and diabetes. Although characterized by chronic hyperglycemia, the underlying cause of T2DM is hyperinsulinemia and insulin resistance, typically as a result of increased energy intake leading to obesity. The ketogenic diet substantially reduces the glycemic response that results from dietary carbohydrate as well as improves the underlying insulin resistance. This review combines a literature search of the published science and practical guidance based on clinical experience. Expert commentary: While the current treatment of T2DM emphasizes drug treatment and a higher carbohydrate diet, the ketogenic diet is an effective alternative that relies less on medication, and may even be a preferable option when medications are not available. PMID- 30289049 TI - Prospective bi-directional associations between sedentary time and physical activity with cognitive performance: a cohort study. AB - This prospective study determined whether: (1) objective physical activity (PA) and sedentary (SED) time at 9 years was associated with cognition at 15 years, (2) cognition at 9 years was associated with PA and SED at 15 years, and (3) the change in PA and SED from 9 to 15 years was associated with the change in cognition. Cognitive performance was assessed from picture vocabulary, verbal analogy, passage comprehension, and applied problem tasks. Regression models were used to explore each aim while adjusting for covariates. Among the combined sample, SED (min. day-1) at 9 years was unrelated with cognitive performance at 15 years, whereas participating in >= 60 min. day-1 of moderate-to-vigorous PA (MVPA) at 9 years predicted lower cognitive scores at 15 years. In the reverse direction, cognitive performance at 9 years was unrelated with SED and MVPA (min. day-1) at 15 years. Over 6 years, increased SED (min. day-1) predicted lower improvement to verbal analogy scores (B = -0.01, p = 0.028). In comparison, an increase (or relatively smaller decline) in MVPA (min. day-1) predicted greater improvement in applied problem scores (B = 0.06, p = 0.007). Contextual information regarding SED and MVPA behavior would help understand bi-directional associations of activity and cognition. PMID- 30289050 TI - Characteristics, behaviours and readiness of persons seeking hearing healthcare online. AB - This study describes characteristics, behaviours and readiness of people who are interested in seeking hearing healthcare (HHC) online. A non-profit clinic was established from which services through a virtual clinic are offered. Most of the patient-audiologist interactions are conducted online. We used online means to invite individuals to take a free online digit-in-noise (DIN) test. Upon failing the test, individuals reported their readiness to seek HHC by using two tools: the line and the staging algorithm. Individuals >=18 years of age, within the greater Durban area, South Africa, were eligible to participate in the study. A total of 462 individuals completed the online DIN test during the first 3 months. Of those, 58.66% (271/462) failed the test and 11.04% (51/462) submitted their details for further contact from the clinic audiologist. Five individuals proceeded to a comprehensive hearing evaluation and hearing aid trial: all those individuals showed readiness to seek further HHC on the measurement tools. These individuals have reported knowing of their hearing challenges prior to taking the test and have waited for a period of between 5 and 16 years before seeking HHC. A significant association between age and DIN test result was found. This explorative study is the first clinic to utilise digital tools across the entire patient journey in combination with face-to-face interactions in providing HHC. Internet-connected devices provide an opportunity for individuals to seek HHC and for providers to offer initial services to detect, counsel and support persons through the initial engagement process of seeking HHC. This may open up new audiology patient pathways through online hearing screening, assessment of readiness to seek further HHC and enhancement of service delivery using hybrid services by combining online and face-to-face modes of synchronous and asynchronous communication. PMID- 30289051 TI - Adolescent attachment insecurity and the influence of MBT. AB - The aim of this study in a high-risk adolescent sample with personality disorders receiving intensive mentalisation-based treatment (MBT), was first, to examine deviations in insecure attachment distribution of the normative pattern, and in borderline personality disorder and other personality disorders; second, to explore whether MBT alters attachment representations and whether these alterations are related to changes in psychological distress. A total of 60 adolescents were investigated pre-treatment for both categorical and continuous measures of the Adult Attachment Interview (AAI). Pre- and post-AAI (N = 33) data were compared with psychological distress measured by the Symptom Checklist-90. While the most disturbed category of insecure attachment, the "cannot classify" category, was overrepresented (46.7%) at pre-treatment, no differences were observed by type of personality disorder. At post-treatment, 48.5% of the participants showed positive change in the attachment representation, and their psychological distress lowered significantly (p = .002). The whole sample demonstrated change towards increased secure attachment (z = -2.85, p = .004). Attachment insecurity was found in all adolescent personality disorders which MBT seemed to be able to alter. However, as we included no control group, we cannot conclude that changes are due to the treatment itself. PMID- 30289052 TI - Management and prognosis of cancers in the accessory parotid gland. AB - Objective This study was performed to analyze the clinical management of accessory parotid gland (APG) cancer and possible risk factors for disease related death. Methods Patients diagnosed with primary APG cancers in the largest medical center in Northeast China were enrolled from January 1990 to December 2016. Results All 43 patients underwent resection of the tumors and superficial parotid gland by a standard Blair incision. Seven (16.3%) patients also required selective neck dissection. The most common lesion was mucoepidermoid carcinoma. Temporary facial paralysis occurred in 11 (25.6%) patients, and permanent facial paralysis occurred in 3 (7.0%) patients because of surgical resection of the facial nerve, which was involved with the tumor. The 5- and 10-year disease specific survival rates were 86.0% and 66.0%, respectively. The tumor stage, neck status, neck dissection, and tumor grade were significantly associated with disease-related death, but only the tumor grade was an independent risk factor. Conclusion Superficial parotidectomy is a reliable surgical procedure associated with a high survival rate and low morbidity in treating APG cancers. The tumor grade is the key prognostic factor. PMID- 30289053 TI - Multimodal antidepressant vortioxetine causes analgesia in a mouse model of chronic neuropathic pain. AB - Vortioxetine is a multimodal antidepressant that potently antagonizes 5-HT3 serotonin receptors, inhibits the high-affinity serotonin transporter, activates 5-HT1A and 5-HT1B receptors, and antagonizes 5-HT1D and 5-HT7 receptors. 5-HT3 receptors largely mediate the hyperalgesic activity of serotonin that occurs in response to nerve injury. Activation of 5-HT3 receptors contributes to explain why selective serotonin reuptake inhibitors, such as fluoxetine, are not indicated in the treatment of neuropathic pain. Here, we studied the analgesic action of vortioxetine in the chronic constriction injury model of neuropathic pain in mice. Vortioxetine was injected once a day for 27 days at doses (10 mg/kg, intraperitoneally) that determine >90% 5-HT3 receptor occupancy in the central nervous system. The action of vortioxetine was compared to the action of equal doses of the serotonin-noradrenaline reuptake inhibitor, venlafaxine (one of the gold standard drugs in the treatment of neuropathic pain), and fluoxetine. Vortioxetine caused a robust analgesia in chronic constriction injury mice, and its effect was identical to that produced by venlafaxine. In contrast, fluoxetine was inactive in chronic constriction injury mice. Vortioxetine enhanced mechanical pain thresholds in chronic constriction injury mice without changing motor activity, as assessed by the open-field and horizontal bar tests. None of the three antidepressants caused analgesia in the complete Freund's adjuvant model of chronic inflammatory pain. These findings raise the attractive possibility that vortioxetine can be effective in the treatment of neuropathic pain, particularly in patients with comorbid depression and cognitive dysfunction.

AB - The stem cell and regenerative medicine arena has become increasingly complicated in recent years with thousands of people involved. There are as many as a dozen or more main groups of stakeholders, who together may be viewed as one ecosystem that is now rapidly evolving. The nature of the ecosystem and its evolution have major implications for not just those within it, but also for medicine and society at large. Here, I describe this ecosystem and its evolution, as well as the negative impacts within the ecosystem of a constellation of hundreds of unproven for-profit clinics and related businesses. Finally, I propose approaches for how to positively influence and drive the future of the global stem cell ecosystem. PMID- 30289056 TI - Who enrols in voluntary micro health insurance schemes in low-resource settings? Experience from a rural area in Bangladesh. AB - BACKGROUND: Micro health insurance (MHI) has proved to be a potential health financing tool for many developing countries. Bangladesh also included MHI in its current health-financing strategy which aims to achieve universal health coverage. However, low uptake, low renewal and high dropouts have historically challenged financial sustainability of these schemes. OBJECTIVE: This study aims to identify factors influencing people from low-resource settings, particularly those from Bangladesh, to enrol in MHI schemes. METHODS: The study analyses the 'Amader Shasthya' MHI scheme operating in Chakaria, a sub-district under Cox's Bazar district, Bangladesh. A household survey was carried out during May-June 2016 among 2,000 households from the scheme coverage area. The Outreville's insurance-demand framework was used to identify enrolment influencing factors. Multivariate logistic regression analysis was carried out to identify significant influencing factors of enrolment. RESULTS: Enrolment influencing factors were identified in four dimensions: economic, socio-cultural, demographic and structural. Households with the main income earner having 10+ years of schooling (odds 1.9 [CI 1.2-2.9] compared to illiterate), having financial literacy (odds 1.5 [CI 1.2-1.8] compared to financially illiterate) and being a public/private service holder (odds 1.6 [CI 1.1-2.4] compared to menial labour) were more likely to enrol. Membership in development programmes of NGOs also influenced enrolment decision significantly (odds 1.3 [CI 1.0-1.5]). The presence of chronic illness in household encouraged enrolment (odds 1.5 [CI 1.2-1.8]). Households living closer to health centres were more likely to enrol (odds 2.1 [CI 1.6-2.7]) compared to those living further away. CONCLUSION: The findings are expected to have significant implications in terms of designing similar health insurance schemes, particularly in terms of designing demand-driven and context adapted schemes that have greater potential to attract a larger client pool, ensure effective risk pooling and eventually expedite the achievement of universal health coverage in low-resource settings. PMID- 30289054 TI - Assessing the function of pneumococcal neuraminidases NanA, NanB and NanC in in vitro and in vivo lung infection models using monoclonal antibodies. AB - Streptococcus pneumoniae isolates express up to three neuraminidases (sialidases), NanA, NanB and NanC, all of which cleave the terminal sialic acid of glycan-structures that decorate host cell surfaces. Most research has focused on the role of NanA with limited investigations evaluating the roles of all three neuraminidases in host-pathogen interactions. We generated two highly potent monoclonal antibodies (mAbs), one that blocks the enzymatic activity of NanA and one cross-neutralizing NanB and NanC. Total neuraminidase activity of clinical S. pneumoniae isolates could be inhibited by this mAb combination in enzymatic assays. To detect desialylation of cell surfaces by pneumococcal neuraminidases, primary human tracheal/bronchial mucocilial epithelial tissues were infected with S. pneumoniae and stained with peanut lectin. Simultaneous targeting of the neuraminidases was required to prevent desialylation, suggesting that inhibition of NanA alone is not sufficient to preserve terminal lung glycans. Importantly, we also found that all three neuraminidases increased the interaction of S. pneumoniae with human airway epithelial cells. Lectin-staining of lung tissues of mice pre-treated with mAbs before intranasal challenge with S. pneumoniae confirmed that both anti-NanA and anti-NanBC mAbs were required to effectively block desialylation of the respiratory epithelium in vivo. Despite this, no effect on survival, reduction in pulmonary bacterial load, or significant changes in cytokine responses were observed. This suggests that neuraminidases have no pivotal role in this murine pneumonia model that is induced by high bacterial challenge inocula and does not progress from colonization as it happens in the human host. PMID- 30289058 TI - Source flexibility in schizophrenia: specificity and role in auditory hallucinations. AB - INTRODUCTION: One important aspect of human cognition relies on the ability to bias attention towards stimulus-independent and stimulus-oriented thoughts and to switch between these states - or source flexibility. This mechanism has received very little attention in the literature, and in particular in schizophrenia. Moreover, there is good reason to believe that this mechanism could also be implicated in hallucinations, but this hypothesis has never been examined. Thus, the aim of the present study was, for the first time in the literature, to explore source flexibility abilities in schizophrenia and their potential relations with auditory hallucinations. METHODS: Forty persons diagnosed with schizophrenia and 26 healthy controls were evaluated with tasks assessing source flexibility, cognitive flexibility and processing speed. Patients were also assessed with a measure of hallucinations and delusions. RESULTS: Results revealed that persons diagnosed with schizophrenia presented a poorer performance than healthy controls for source flexibility. Moreover, results demonstrated that source flexibility performance could not be explained by a more general impairment of processing speed or buy difficulties in cognitive flexibility. Finally, source flexibility was found to be related to hallucinations. CONCLUSIONS: Source flexibility plays an important role in schizophrenia and in particular is a cognitive mechanism involved in hallucinations. PMID- 30289057 TI - Application of PLGA/FGF-2 coaxial microfibers in spinal cord tissue engineering: an in vitro and in vivo investigation. AB - AIM: Scaffolds are a promising approach for spinal cord injury (SCI) treatment. FGF-2 is involved in tissue repair but is easily degradable and presents collateral effects in systemic administration. In order to address the stability issue and avoid the systemic effects, FGF-2 was encapsulated into core-shell microfibers by coaxial electrospinning and its in vitro and in vivo potential were studied. Materials & methods: The fibers were characterized by physicochemical and biological parameters. The scaffolds were implanted in a hemisection SCI rat model. Locomotor test was performed weekly for 6 weeks. After this time, histological analyses were performed and expression of nestin and GFAP was quantified by flow cytometry. Results: Electrospinning resulted in uniform microfibers with a core-shell structure, with a sustained liberation of FGF-2 from the fibers. The fibers supported PC12 cells adhesion and proliferation. Implanted scaffolds into SCI promoted locomotor recovery at 28 days after injury and reduced GFAP expression. CONCLUSION: These results indicate the potential of these microfibers in SCI tissue engineering. [Formula: see text].

AB - Cryptochrome is a flavin-binding blue-light photoreceptor that functions in growth and development in plants, the circadian clock in animals and navigation in birds. However, a lack of purified cryptochrome has hindered studies of the structure and function of this protein. In this study, we obtained a substantial amount of the Columbia livia Cryptochrome1 (ClCry1) protein by using a prokaryotic expression system. In addition, we performed comprehensive experiments to assess the influence of several factors on the purification and yield of ClCry1, such as the inducer that was used, temperature, duration of expression and type of growth medium. These assays clearly indicated that such factors influenced the purification and yield of ClCry1. Moreover, flavin adenine dinucleotide (FAD) was added during expression and purification of ClCry1, which resulted in production of large amounts of ClCry1 protein with the FAD cofactor from the Escherichia coli (E. coli) heterologous expression system. We believe that this study provides a novel avenue to acquire large amounts of ClCry1 that contains FAD and lays the foundation for studies of the geomagnetic navigation mechanism of Aves. PMID- 30289061 TI - BaltPLA2: a new phospholipase A2 from Bothrops alternatus snake venom with antiplatelet aggregation activity. AB - In last decades, snake venoms have aroused great interest of the medicine due to the pathophysiological effects caused by their toxins. These include the phospholipases A2, low molecular weight proteins capable of causing haemorrhagic, myotoxic, inflammatory and neurotoxic effects after an ophidian accident. The present work describes the isolation and biochemical characterization of a new PLA2 isolated from the B. alternatus snake venom, which was named BaltPLA2. The rapid and efficient purification of this toxin was performed using only two chromatography steps (anion exchange and hydrophobic chromatography). BaltPLA2 is an acidic protein (pI 4.4) with an apparent molecular mass of 17000 (SDS-PAGE) and 14074.74 Da (MALDI TOF/TOF). Analysis of fragments ion by MS / MS showed the following internal amino acid sequence SGVIICGEGTPCEK, which did not exhibit homology with other PLA2 from the same venom. BaltPLA2 is a catalytically active, which displayed an anticoagulant action, inhibition of platelet aggregation induced by epinephrine (~ 80%) and ADP (24%). BaltPLA2 also was able to induce myonecrosis and the release of cytokines (IL-10, IL-12 and TNF-alpha) in macrophages culture. The results presented in this work greatly contribute to a better understanding of the mechanism of enzymatic and pharmacological actions of PLA2s from snake venoms and they may contribute to its application in medical research. PMID- 30289062 TI - QRPR and HCQRPQ, two peptides from soybean, have an inhibitory effect on the proliferation of HepG2 cells. AB - In this study, we investigated the possible inhibitory effect of soy peptides QRPR and HCQRPQ on human liver cancer cells (HepG2) and their underlying mechanisms. An MTS assay showed that QRPR used in combination with HCQRPQ had a significant inhibitory effect on the proliferation of HepG2 cells compared to the effect of QRPR or HCQRPQ alone, and the cytotoxicity was low. An Annexin V/PI assay revealed that QRPR used in combination with HCQRPQ induced apoptosis in HepG2 cells; this outcome was also confirmed by the increased expression of caspase-3. The ultrastructural changes of cells induced by soybean peptides were observed via transmission microscopy. In addition, the combination of QRPR and HCQRPQ had a significant effect on the cell cycle of HepG2 cells compared with the effect of the control group. Using the real-time quantitative reverse transcriptase-polymerase chain reaction method, the mRNA expression levels of caspase-8 were significantly increased by QRPR used in combination with HCQRPQ (P < 0.001). Western blot results showed that QRPR used in combination with HCQRPQ increased the expression of caspase-8 and caspase-3 in a dose- and time-dependent manner. ELISA showed that the combination of QRPR and HCQRPQ reduced the secretion of TNF-alpha. We speculated that QRPR used in combination with HCQRPQ exerts its inhibitory effect possibly through the TNF-alpha mediated pathway. Taken together, all results suggested the promising chemotherapeutic potential of QRPR and HCQRPQ for the treatment of hepatocellular carcinoma. PMID- 30289063 TI - Structural Insights on the Obscurin-Binding Domains in Titin. AB - INTRODUCTION: The giant muscular proteins titin and obscurin bind to each other at the Z-disk during muscle development. This binding event is mediated through two domains from each protein: ZIg9/10 from titin and Ig58/59 from obscurin. This interaction helps stabilize and organize the sarcomere; ablation of this binding leads to muscular dystrophy. OBJECTIVE: Here we solve the high-resolution solution structure of titin ZIg10 and further delineate which sections of titin bind to obscurin. MATERIALS AND METHODS: Solution NMR, Circular Dichroism, and SEC-MALS were used to biophysically characterize the titin domains involved in this titin-obscurin interaction. RESULTS AND CONCLUSION: We present the high resolution solution structure of titin ZIg10. Additionally, we show that titin ZIg9 drives the titin-obscurin interaction, while ZIg10 does not actively participate in the titin-obscurin interaction but instead acts to stabilize ZIg9. PMID- 30289064 TI - Neuroprotective effects of extracts from the radix Curcuma aromatic on H2O2 induced damage in PC12 cells. AB - : Aim & objectives: Curcumins, also known as diarylheptanoids, are regarded as characteristic constituents in Curcuma, which have obviously neuroprotective activities against oxidative stress. As one of Traditional Chinese Medicines from Curcuma, the radix of Curcuma aromatic is also rich in curcumins, but its neuroprotective activity and underlying mechanism remains unknown. The aim of current study is to evaluate the neuroprotective effects of different extracts from the radix of C. aromatic (ECAs) on hydrogen peroxide (H2O2) -damaged PC12 cells. MATERIAL AND METHODS: The model of oxidative stress damage was established by treatment of 400 uM hydrogen peroxide (H2O2) on PC12 to induce cell damage. After the treatment of ECWs for 24 h, the cell viability, the release rate of lactate dehydrogenase (LDH), and the activities of superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH) were measured to evaluate the neuroprotection of ECAs on that model. The possibly protecting mechanism of oxidative damage by measurement of level of ROS, cell apoptosis rate, mitochondrial membrane potential (MMP), morphologic change, the intracellular Ca2+ content (F340/F380) and the expressions of Bcl-2, Bax and Caspase-3. Additionally, the constituents from those extracts were analyzed by HPLC-DAD-Q TOF-MS method. RESULTS: Compared with a positive control, Vitamin E, 10 ug/ml of 95 % EtOH extract (HCECA) and 75 % EtOH extract (MCECA) can markedly increase the rate of cell survival and enhance the antioxidant enzyme activities of SOD, CAT, increase the levels of GSH, decrease LDH release and the level of ROS, attenuate the intracellular Ca2+ overloading, reduce the cell apoptotic rate and stabilize MMP, down-regulate Bcl-2 expression, up-regulate Bax and caspase-3 expression, improve the change of cell morphology. The chemical analysis showed diarylheptanoids and sesquiterpenoids are the major chemicals in those extracts and the former was richer in HCECA and MCECA than others. CONCLUSIONS: These findings indicated that the effects of HCECA and MCECA on inhibiting the cells damage induced by H2O2 in PC12 are better than other extracts from the radix of C. aromatic through the mechanisms of apoptosis inhibition in PC12, and the active constituents with neuroprotective effects consisting in those two extracts are diarylheptanoids.

AB - Surface Enhanced Raman Spectroscopy (SERS) has long history as ultrasensitive platform for the detection of biological species from small aromatic molecules to complex biological systems as circulating tumor cells. Thanks to unique properties of graphene, the range of SERS applications has largely expanded. Graphene is efficient fluorescence quencher improving quality of Raman spectra. It contributes also to the SERS enhancement factor through the chemical mechanism. In turn, the chemical flexibility of reduced graphene oxide (RGO) enables tunable adsorption of molecules or cells on SERS active surfaces. Graphene oxide composites with SERS active nanoparticles have been also applied for Raman imaging of cells. This review presents a survey of SERS assays employing graphene or RGO emphasizing the improvement of SERS enhancement brought by graphene or RGO. The structure and physical properties of graphene and RGO will be discussed too. PMID- 30289066 TI - Advances in gene therapy for erectile dysfunction: promises and challenges. AB - Erectile dysfunction (ED) is a major health problem in men. Over the past few decades, oral phosphodiesterase type 5 (PDE5) inhibitors have been adopted as the recommended strategy to treat ED in the majority of cases. However, these oral medications require on-demand access and are not effective in some hard-to-treat populations. Other alternative treatments are also not satisfactory. In recent years, a novel therapeutic approach against ED, gene therapy, has shown great potential in preclinical models designed to provide long-term improvement of erectile function and the underlying conditions. Gene therapy refers to the use of viral and non-viral vectors to deliver therapeutic genes to tissues via direct or transduced cell-mediated approaches. With the growing knowledge of the molecular mechanisms involved in the pathophysiology of ED, a number of therapeutic gene strategies have been extensively tested and proven to be effective in many animal models. However, only few of them have been evaluated in clinical trials. Safety concerns are the major obstacles to be addressed before clinical application can be considered. In this review, we summarize the advancements in gene therapy for ED treatment, with an emphasis on the emerging stem cell-based approaches, as well as other combinational strategies. The challenges facing its future application for ED treatment are also discussed. PMID- 30289067 TI - Bone Minimodeling, a Special Modeling Pattern and Potential as Therapeutic Target for Osteoporosis. AB - The concept of minimodeling is defined as a kind of focal bone formation that features the absence of preceding bone absorption by osteoclasts. In the process of minimodeling, osteogenetic and osteoclastic activities are decoupled. Linear boundary between old bone and new bone can be discovered. Frost et al. presumed that minimodeling in trabeculae can continue throughout life. The concept of minimodeling is not new, however its function and nature are still imperfectly understood. Our review will focus on minimodeling-based formation in 5 aspects below: 1. compare the minimodeling with remodeling regarding 10 items; 2. describe the histological observation to characterize remodeling and minimodeling formation sites; 3. present evidence of bone anabolic agents which start bone minimodeling; 4. discuss the mechanism and target cells involved in bone minimodeling; 5. interpretate the increased osteogenic potential and trabecular connectivity with minimodeling-based formation; 6. Depict modeling patterns of the bone implant interface and peri-implant osteogenesis in osteoporosis. This review provides an in-depth knowledge regarding minimodeling comprehensively and its potential contributions in skeletal homeostasis and application prospect in improving the success rate of dental implant in osteoporosis. PMID- 30289068 TI - Co-Existence of Novel PDE6A Mutations and A Recurrent RPGR Mutation: A Potential Explanation for Phenotypic Diversity in Female RPGR Mutation Carriers. AB - BACKGROUND: To report the co-existence of novel biallelic PDE6A mutations and heterozygous RPGR mutation in a Chinese female patient with retinitis pigmentosa (RP), and to analyze the intrafamilial phenotypic diversity. METHODS: Three patients with retinopathy and four healthy family members were included in genetic and clinical analyses. Personal medical records were obtained from another four unaffected female family members who refused blood donation. Family history was carefully recorded. Each patient received comprehensive ophthalmic tests. Targeted next-generation sequencing (NGS) approach was performed on the proband to determine the retinopathy causative mutation for this family. In silico analysis was also applied to analyze the pathogenesis of identified mutations. RESULTS: The two recruited male patients were diagnosed with RP, and the female patient RP sine pigmento (RPSP). Genetic assessments revealed a recurrent RPGR mutation, c.1926_1927insA, carried by all three patients and segregated the disease status. Three other unaffected female family members were confirmed as carriers for the identified RPGR mutation, and another four as obligate carriers. Interestingly, of all the eight female RPGR mutation carriers in this family, only one female developed retinal dystrophy. Comprehensive genetic analysis of this patient unraveled additional biallelic PDE6A mutations, c.[1066-9delT];[2324delG], carried solely by this individual. CONCLUSIONS: Taken together, we hypothesize that the phenotypic variability presented by female RPGR mutation carriers may be attributed to the co-existence of other disease causative mutations. Our study also emphasizes the importance of comprehensive genetic analysis in these female carriers, which will contribute to better diagnosis, prognosis, and treatment for these patients. PMID- 30289069 TI - Coding and Non-coding: Molecular Portrait of GIST and its Clinical Implication. AB - Gastrointestinal stromal tumours are the most common mesenchymal tumours of the gastrointestinal tract. Despite similar mutation pattern of activating mutations in KIT or PDGFRA receptors in 85% of cases, they demonstrate significantly heterogeneous clinical behaviour and pathological characteristics. This heterogeneity opens the question of the role of other factors and mechanisms of regulation in the development of GIST. Additional mutations in downstream effectors of GIST related signalling pathways or aberrant expression of non coding RNAs may be additional contributing factors, the latter being increasingly recognized in carcinogenesis in general. Recently, a substantial progress has been achieved in understanding the functional roles of lncRNAs in GIST suggesting their potential employment as biomarkers and therapeutic targets in GIST. Moreover, some miRNAs have recently been found to be able to sensitize cells to imatinib, which could be an attractive option to overcome the resistance to the drug, which hampers the efficacy of GIST treatment. Therefore, the advantage can be taken of both coding and non-coding parts of the genome in order to significantly improve prognostication and help find personalized therapy for patients, depending on a subtype of GIST and personal characteristics. PMID- 30289070 TI - Genetic Modifiers of Fetal Haemoglobin (HbF) and Phenotypic Severity in beta Thalassemia Patients. AB - BACKGROUND: The phenotypic severity of beta-thalassemia is highly modulated by three genetic modifiers: beta-globin (HBB) mutations, co-inheritance of alpha thalassemia and polymorphisms in the genes associated with fetal haemoglobin (HbF) production. This study was aimed to evaluate the effect of HbF related polymorphisms mainly in the HBB cluster, BCL11A (B-cell CLL/lymphoma 11A) and HBS1L-MYB (HBS1-like translational GTPase-MYB protooncogene, transcription factor) with regards to clinical severity. METHODS: A total of 149 patients were included in the study. HBA and HBB mutations were characterised using multiplex PCR, Sanger sequencing and multiplex ligationdependent probe amplification. In addition, 35 HbF polymorphisms were genotyped using mass spectrometry and PCR restriction fragment length polymorphism (PCRRFLP). The genotype-phenotype association was analysed using SPSS version 22. RESULTS: Twenty-one HBB mutations were identified in the study population. Patients with HBB mutations had heterogeneous phenotypic severity due to the presence of other secondary modifiers. Co-inheritance of alpha-thalassemia (n = 12) alleviated disease severity of beta-thalassemia. In addition, three polymorphisms (HBS1LMYB, rs4895441 [P = 0.008, odds ratio (OR) = 0.38 (0.18, 0.78)], rs9376092 [P = 0.030, OR = 0.36 (0.14, 0.90)]; and olfactory receptor [OR51B2] rs6578605 [P = 0.018, OR = 0.52 (0.31, 0.89)]) were associated with phenotypic severity. Secondary analysis of the association between single-nucleotide polymorphisms with HbF levels revealed three nominally significant SNPs: rs6934903, rs9376095 and rs9494149 in HBS1L-MYB. CONCLUSION: This study revealed 3 types of HbF polymorphisms that play an important role in ameliorating disease severity of beta-thalassemia patients which may be useful as a predictive marker in clinical management. PMID- 30289071 TI - MiR-19b Functions as a Potential Protector in Experimental Autoimmune Encephalomyelitis. AB - BACKGROUND: MicroRNA-19b (miR-19b) is essential in determining oligodendroglia proliferation. Phosphatase and tensin homologue on chromosome 10 (PTEN) is considered the target of miR-19b and participates in oligodendrocyte differentiation and proliferation. METHODS: Murine EAE was induced by myelin oligodendrocyte glycoprotein (MOG35- 55). For EAE reversal, artificially synthesized agomiR-19b was intravenous injected after immunization. RESULTS: We found that the expression of miR-19b is significantly reduced in an experimental autoimmune encephalomyelitis (EAE) mouse model. This downregulation, which is associated with the neurological scores, can be dramatically ameliorated by agomiR-19b. Our results show that agomiR-19b increases the expression of myelin basic protein (MBP) and cyclic nucleotide phosphodiesterase (CNP), which are regularly utilized as molecular markers of oligodendrocytes. Furthermore, our study also revealed that miR-19b probably affects the expression of PTEN in the EAE model. CONCLUSION: These results indicate that the restoration of miR-19b probably exerts its therapeutic effect by affecting PTEN in the pathogenesis of EAE. PMID- 30289072 TI - Probable Mechanisms Involved in Immunotoxin Mediated Capillary Leak Syndrome (CLS) and Recently Developed Countering Strategies. AB - Antibody-toxin fused agents or immunotoxins, are a newly engineered class of cytotoxic agents consisting of a bacterial or plant toxin moiety hooked up either to a monoclonal antibody or a specific growth factor. Nevertheless, acquiring a full potency in clinic is mostly restricted due to the Capillary leak syndrome (CLS), a serious immune provoked, life-threatening side effect, subsequent to the endothelial damage, resulting in fluid escape from the bloodstream into tissues including lungs, muscle and brain, developing organ failure and eventually death. Proposed underlying mechanisms include direct damage to endothelial cells, acute inflammation, Lymphokine-activated killer (LAK) cells engagement, alteration in cell-cell/cell-matrix connectivities and cytoskeletal dysfunction. Very poor biodistribution and heterogeneous extravasation pattern in tumor site result in accumulation of ITs close to the extravasation site, gradual toxin release and initiation of nearby endothelial cells lysis, secretion of pro-inflammatory cytokines, development of acute inflammation and engagement of Lymphokine activated killer (LAK) cells. Intrinsic immunogenicity of applied toxin moiety is another important determinant of CLS incidence. Toxins with more intrinsic immunogenicity possess more probability for CLS development. Recently, development of new generations of antibodies and mutated toxins with conserved cytotoxicity has partly tapered risk of CLS development. Here, we describe probable mechanisms involved in CLS and introduce some of the recently applied strategies for lessening incidence of CLS as much as possible. PMID- 30289073 TI - VEGFR2 and VEGF-C Suppresses the Epithelial-Mesenchymal Transition Via YAP in Retinal Pigment Epithelial Cells. AB - BACKGROUND: Whereas retinal pigment epithelial (RPE) cells are known to secrete VEGF-A and VEGFR2, the functions of the autocrine VEGF signaling remain unclear. Meanwhile, anti-VEGF therapies have been applied routinely to treat ocular vascular diseases. OBJECTIVE: The aim of this study was to determine the functions of the VEGF signaling in RPE cells and evaluate the consequences of its interruption. METHODS: The genes involved in the VEGF and Hippo signal pathways were knocked down with siRNAs in both ARPE-19 cell line and human primary RPE cells via transient transfection whereas overexpression of VEGFR2 was mediated via adenovirus transduction. Expression of the epithelial-mesenchymal transition (EMT) markers and the downstream genes of YAP were determined by real-time PCR and Western Blot analysis. Immunofluorescence staining was utilized to determine gene expression in tissue and mouse samples. RESULTS: Knockdown of VEGFR2 results in epithelial-mesenchymal transition in vitro and in vivo. Overexpression of VEGFR2 suppresses TGF beta-mediated EMT in RPE cells. Loss of VEGF-C rather than VEGF-A induces EMT. Mechanistically, the VEGFR2 ablation-induced EMT in RPE cells is mediated by activation of YAP, an effector of the Hippo pathway. Finally, the immunohistochemical analysis of VEGFR2 and YAP in human proliferative vitreoretinopathy (PVR) membranes indicates a tendency of an inverse correlation between VEGFR2-positive and YAP-positive cells. CONCLUSIONS: Our results disclose unexpected novel roles of VEGFR2 and VEGF-C in the process of EMT of RPE cells and in the Hippo pathway. The data shown here demonstrated that VEGFR2 and VEGF-C are important to maintain the normal physiological state of RPE cells. PMID- 30289074 TI - Nose to Brain Delivery of Galantamine Loaded Nanoparticles: In-vivo Pharmacodynamic and Biochemical Study in Mice. AB - BACKGROUND: Presence of blood brain barrier is one of the major hurdle in drug delivery to brain for the treatment of neurological diseases. Alternative and more effective drug delivery approaches have been investigated for the drug targeting to brain in therapeutic range. OBJECTIVE: The present investigation was carried out to improve the galantamine bioavailability in brain by intranasal drug delivery through thiolated chitosan nanoparticles and compared to nasal and oral delivery of its solution using pharmacodynamic activity as well as biochemical estimation. METHODS: Thiolated chitosan (modified) nanoparticles were fabricated using modified ionic gelation method and intranasal delivery is evaluated by reversal of scopolamine induced amnesia and biochemical estimation of acetylcholinesterase activity in Swiss albino mice brain. Scopolamine (0.4 mg/kg, i.p.) was used to induce amnesia. Piracetam (400mg/kg, i.p.) was used as positive control. Mice were treated with galantamine solution (4mg/kg) by oral and nasal route and formulated galantamine nanoparticles (equivalent to 4mg/kg) by intranasal administration for 7 successive days and the results were compared statistically. RESULTS: Intranasal delivery of galantamine loaded thiolated chitosan nanoparticles was found significant (p<0.05) as compared to oral and nasal administration of its solution, by pharmacodynamic study and biochemical estimation of acetylcholinesterase activity in Swiss albino mice brain. CONCLUSION: Significant recovery in amnesia induced mice model by intranasal administration of galantamine loaded thiolated chitosan nanoparticles established the relevance of nose to brain delivery over the conventional oral therapies for the treatment of Alzheimer's disease. PMID- 30289075 TI - Asymmetric Changes in Limbic Cortex and Planum Temporale in Patients with Alzheimer Disease. AB - BACKGROUND: There are several cortical areas related to the limbic system that form the output from the hippocampal formation whose cellular and morphological features are important for the onset and progression of AD. We hypothesized that there would be a significant difference in the size of cortical pyramidal neurons and that there would also be a hemispheric asymmetry between Alzheimer disease patients and controls. These differences would potentially be accompanied by an increase in the numbers of Fluoro-Jade B-positive degenerating cortical neurons and a corresponding decrease in the numbers of DAPI-stained cortical neuronal nuclei in subjects with AD compared to controls. Such changes could potentially be used as another marker in postmortem neuropathological diagnosis of AD. METHODS: We measured absolute numbers of DAPI and Fluoro-Jade B stained cells in five cortical areas of the limbic system and four subareas of planum temporale in the post-mortem brains of subjects with Alzheimer disease. We also measured the size of pyramidal neurons in layer III in the five cortical areas of the limbic system in these subjects. All measurements were performed separately for the left and right hemisphere in order to identify asymmetries between the two hemispheres. RESULTS: We observed a significant decrease in numbers of DAPI stained cells in layers IV-VI of the anterior cingulate gyrus on the right side, in layers I-III of the posterior cingulate gyrus on the left side, in layers IV VI in the transition region from superior temporal gyrus into planum temporale on the right and in layers IV-VI in the transition from planum temporale to insular cortex on the left. We also observed a significant increase in the numbers of Fluoro-Jade stained cells in layers I-III of the anterior cingulate gyrus and in layers I-III on the left and layers IV-VI of the right gyrus of Heschl. Shortening of the size of layer III pyramidal neurons in subjects with Alzheimer's disease was found in the anterior cingulate gyrus on the right, in the posterior cingulate gyrus and entorhinal cortex on the left and on the right in the parahippocampal gyrus. CONCLUSION: Our study demonstrates asymmetries in different cortical regions of the temporal lobe that can be used as another marker in the postmortem diagnosis of AD. PMID- 30289076 TI - The Implications of Autophagy in Alzheimer's Disease. AB - The pathogenic mechanisms of Alzheimer's Disease (AD) involve the deposition of abnormally misfolded proteins, amyloid beta protein (Abeta) and tau protein. Abeta comprises senile plaques, and tau aggregates form Neurofibrillary Tangles (NFTs), both of which are hallmarks of AD. Autophagy is the main conserved pathway for the degeneration of aggregated proteins, Abeta, tau and dysfunctional organelles in the cell. Many animal model studies have demonstrated that autophagy normally functions as the protective factor against AD progression associated with intracytoplasmic toxic Abeta and tau aggregates. The upregulation of autophagy can also be favorable in AD treatment. An improved understanding of the signaling pathways that regulate autophagy is critical to developing AD treatments. The cellular and molecular machineries of autophagy, their function in the pathogenesis of AD, and current drug discovery strategies will be discussed in this review. PMID- 30289077 TI - The association of neuronal stress with activating transcription factor 3 in dorsal root ganglion of in vivo and in vitro models of bortezomib-induced neuropathy. AB - The notion that proteasome inhibitor bortezomib (BTZ) induced intracellular oxidative stress resulting in peripheral neuropathy has been generally accepted. The association of mitochondrial dysfunction, cell apoptosis, and endoplasmic reticulum (ER) stress with intracellular oxidative stress is ambiguous and still needs to be investigated. Here we report a mechanism underlying the action of BTZ induced intracellular oxidative stress, mitochondrial dysfunction, cell apoptosis, and ER stress via the activation of activating transcription factor 3 (ATF3) in primary cultured dorsal root ganglion (DRG) neurons and in DRG from painful peripheral neuropathic rats. ATF3 is a stress-hub gene which was upregulated in DRG neurons after different kinds of peripheral nerve injuries. In the present study, BTZ administration caused the upregulation of ATF3 paralleled with intracellular oxidative stress, mitochondrial dysfunction, cell apoptosis, and ER stress in DRG neurons both in vitro and in vivo. Blocking ATF3 signaling by small interfering RNA (siRNA) gene silencing technology resulted in decreased intracellular oxidative stress, mitochondrial dysfunction, cell apoptosis, and ER stress in DRG neurons after BTZ treatment. This study exhibited important mechanistic insight into how BTZ induces neurotoxicity through the activation of ATF3 resulting in intracellular oxidative stress, mitochondrial dysfunction, cell apoptosis, and ER stress and provided a novel potential therapeutic target by blocking ATF3 signaling. PMID- 30289078 TI - Burden of Congenital Rubella Syndrome (CRS) in Bangladesh: Systematic review of existing literature and transmission modelling of sero-prevalence studies. AB - Background and objectives Congenital Rubella Syndrome (CRS) is the leading cause of vaccine preventable congenital anomalies. Comprehensive country-level data on the burden of CRS in low and middle-income countries, such as Bangladesh, are scarce. This information is essential for assessing the impact of rubella vaccination programs. We aim to systematically review literature on the epidemiology of CRS and estimate the burden of CRS in Bangladesh. Methods We conducted a systematic review of existing literature and transmission modelling of sero-prevalence studies to estimate the pre-vaccine period burden of CRS in Bangladesh. OVID Medline (1948 - 23 November 2016) and OVID EMBASE (1974 - 23 November 2016) were searched using a combination of database specific controlled vocabulary and free text terms. We used an age-stratified deterministic model to estimate the pre-vaccination burden of CRS in Bangladesh. Findings Ten articles were identified, published between 2000 and 2014, including seven cross-sectional studies, two case series and one analytical case-control study. Rubella sero positivity ranged from 47.0% to 86.0% among all age population. Rubella sero positivity rose with age. Rubella sero-positivity among women of childbearing age was 81.0% overall. The estimated incidence of CRS was 0*99 per 1,000 live births, which corresponds to approximately 3,292 CRS cases annually in Bangladesh. Conclusion The estimated burden of CRS in Bangladesh during the pre-vaccination period was high. This will provide important baseline information to assess the impact and cost-effectiveness of routine rubella immunisation, introduced in 2012 in Bangladesh. PMID- 30289079 TI - Epigenetics in neurodegenerative diseases: the role of histone deacetylases. AB - Imbalance in histone acetylation levels and consequently the dysfunction in transcription are associated with a wide variety of neurodegenerative diseases. Histone proteins acetylation and deacetylation is carried out by two opposite acting enzymes, histone acetyl-transferases and histone deacetylases (HDACs), respectively. In-vitro and in-vivo animal models of neurodegenerative diseases and post mortem brains of patients have been reported overexpressed level of HDACs. In recent past numerous studies have indicated that HDAC inhibitors (HDACIs) might be a promising class of therapeutic agents for treating these devastating diseases. HDACs being a part of repressive complexes, the outcome of their inhibition has been attributed to enhanced gene expression due to heightened histoneacetylation. Beneficial effects of HDACIs has been explored both in preclinical and clinical studies of these diseases. Thus, their screening as future therapeutics for neurodegenerative diseases has been widely explored. In this review, we focus on the putative role of HDACs in neurodegeneration and further discuss their potential as a new therapeutic avenue for treating neurodegenerative diseases. PMID- 30289080 TI - Cushing's Syndrome should be Cited as a Disease with High Cardiovascular Risk in Relevant Guidelines. AB - The intention of the paper is to give rationale and to suggest enlisting Cushing's syndrome (CS) amongst high cardiovascular (CV) risk conditions. A considerable amount of data refers to several-fold amplified mortality in CS. The causes are based on high occurrence of many CV risk factors in persons with CS (e.g., adiposity, arterial hypertension, dyslipidemia, as well as diabetes mellitus /DM/). Therefore, practically all individuals with CS have correspondingly the metabolic syndrome (MetSy), which is known as laden with high CV risk. Characteristically, in spite of the young average age, numerous of CS individuals dysplay a 'high' or a 'very high' CV risk, with the risk of a major CV event of over 20% in the following ten years. Although DM is listed as a condition with high cardiovascular risk CS is not, despite the fact that the greater part of CS population have either diabetes mellitus or diagnosed impaired glucose tolerance. CS is stated as a risk factor for aortic dissection in current guidelines, and it should be named as a disease with high CV risk (alike DM and chronic kidney disease) in the relevant guidelines, as well. PMID- 30289082 TI - Evaluation of salivary alkaline phosphatase and albumin in HIV infected patients: A historical cohort study AB - BACKGROUND: Saliva is very important complex biological oral fluid .Antioxidants are present in all body fluids. Uric acid, albumin, vitamins are some of non enzymatic molecular antioxidants.Alkaline phosphatase is related to cell injury and death. Objective: The aim of this study was evaluation of salivary alkaline phosphatase and albumin in HIV positive patients. METHODS: Case group were, 49 HIV positive subjects,compared with 49 healthy control group. Oral clinical examination was carried out . Five ml unstimulated whole saliva was collected during 5 min with Navazesh method. Alkaline phosphatase was determined with spectrophotometric assay. Albumin was assessed by the nephelometric method. RESULTS: The results of this study showed significantly lower salivary albumin in case group in comparison to healthy control group (p= 0.001).HIV positive group had grater alkaline phosphatase than healthy control group. But this difference was not statistically significant (p=0.458). CONCLUSION: Salivary albumin level was significantly decreased and salivary alkaline phosphatase level slightly increased in HIV positive patients in comparison to healthy control group. All of HIV infected patient were in early phase of HIV infection with normal immune status. It could be estimated more salivary changes in late phase and AIDS step. PMID- 30289081 TI - The Gulf Familial Hypercholesterolemia Registry (Gulf FH): Design, Rationale and Preliminary Results. AB - AIM: To determine the prevalence, genetic characteristics, current management and outcomes of familial hypercholesterolaemia (FH) in the Gulf region. METHOD: Adult (18-70 years) FH patients were recruited from 9 hospitals and centres across 5 Arabian Gulf countries. The study was divided into 4 phases and included patients from 3 different categories. In Phase 1, suspected FH patients (category 1) were collected according to the lipid profile and clinical data obtained through hospital record systems. In phase 2, patients from category 2 (patients with previous clinical diagnosis of FH) and category 1 were stratified into definitive, probable and possible FH according to the Dutch Lipid Clinic Network criteria. In phase 3, 500 patients with definitive and probable FH from categories 1 and 2 will undergo genetic testing for 4 common FH genes. In phase 4, these 500 patients with another 100 patients from category 3 (patients with previous genetic diagnosis of FH) will be followed for 1 year to evaluate clinical management and cardiovascular outcomes. The Gulf FH cohort was screened from a total of 34,366 patients attending out-patient clinics. RESULTS: The final Gulf FH cohort consisted of 3,317 patients (mean age: 47+/-12 years, 54% females). The number of patients with definitive FH is 203. In this initial phase of the study, the prevalence of (probable and definite) FH is 1/232. CONCLUSIONS: The prevalence of FH in the adult population of the Arabian Gulf region is high. The Gulf FH registry, a first-of-a-kind multi-national study in the Middle East region, will help in improving underdiagnosis and undertreatment of FH in the region. PMID- 30289084 TI - Mentha pulegium aqueous extract exhibits antidiabetic and hepatoprotective affects in streptozotocin-induced diabetic rats. AB - OBJECTIVE: The aim of this work was to evaluate the antihyperglycemic activity of aerial parts aqueous extract (A.P.A.E) of Mentha pulegium (M. pulegium) on blood glucose levels in normal and streptozotocin(STZ)-induced diabetic rat. Also the glucose tolerance was evaluated in normal rats. Moreover, the histological sections and morphometric analysis at the liver and pancreas have been carried out in this investigation both in normal and STZ-diabetic rats. METHODS: The effect of A.P.A.E of M. pulegium (20 mg/kg) on blood glucose levels was investigated in normal and diabetic rats (n=6). Histopathological changes in liver and pancreas were examined under phase contrast microscope and a preliminary screening for various bioactive constituents was realized according to standard methods. KEY FINDINGS: Both single and repeated oral administration of A.P.A.E (20 mg/kg) caused a significant reduction on blood glucose levels in STZ-diabetic rats (p<0.0001). The morphometric analysis and histological sections realized in pancreas and liver have showed the beneficial effect of the A.P.A.E in cellular population. According to oral glucose tolerance test (OGTT), the aqueous extract has revealed an improvement of glucose tolerance in normal rat. Furthermore the preliminary phytochemical screening of A.P.A.E of M. pulegium has demonstrated the presence of various metabolite compounds including polyphenols, flavonoids, terpenoids tannins, cyanidins, sesquiterpenes, and glycosides. CONCLUSION: we conclude that the A.P.A.E of M. pulegium (20 mg/kg) exhibits a potent antihyperglycemic activity in STZ diabetic rats. PMID- 30289083 TI - Extra-thoracic Extrinsic Compression: An Unusual Cause of Dysphagia. AB - BACKGROUND: Dysphagia affects one in twenty-five adults yearly in the United States. OBJECTIVE: While dysphagia may be common, the prevalence of dysphagia may be underestimated primarily due to under-reporting. Dysphagia may be caused by intraluminal, intrinsic, extrinsic, or motility disorders. METHOD/RESULTS: We present a case of dysphagia caused by extra-thoracic extrinsic compression due to bra use. CONCLUSION: Despite many published reports on dysphagia caused by other diagnoses, we occasionally overlook extrinsic abdominal compression as the culprit for dysphagia. PMID- 30289085 TI - Potential impact of microRNA-423 gene variability in coronary artery disease. AB - AIM: Studies have evaluated the association of miRNA-423 C>A genotyping with the susceptibility to coronary artery disease but the results were contradictory. However, no studies have reported the association between miRNA-423 rs6505162 C>A polymorphism and susceptibility of coronary artery disease. MicroRNAs regulate expression of multiple genes involved in atherogenesis. Therefore, we investigated the association of microRNA-423C>T gene variations with susceptibility to coronary artery disease. METHODOLOGY: This study was conducted on 100 coronary artery disease patients and 117 matched healthy controls. The ggenotyping of the microRNA-423 rs6505162C>A was performed by using Amplification refractory mutation system PCR method (ARMS-PCR). RESULTS: A significant difference was observed in the genotype distribution among the coronary artery disease cases and sex-matched healthy controls (p=0.042). The frequencies of all three genotypes CC, CA, AA reported in the patient's samples were 38%, 56% and 23% and in the healthy controls samples were 64%,48% and 4% respectively. Our findings showed that the microRNA-423 C>A variant was associated with an increased risk of coronary artery disease in codominant model (OR = 1.96, 95 % CI, 1.12-3.42; RR 1.35(1.05-1.75, p=0.017) of microRNA-423CA genotype and significant association in dominant model (OR 1.97(1.14.14-3.39), p=0.014) (CA+AA vs CC) and non-significant association for recessive model (OR=1.42, 95%CI=0.42 4.83, P=0.56, AA vs CC+CA).While, the A allele significantly increased the risk of coronary artery disease (OR =1,56, 95 % CI, 1.03-2.37; p=0.035) compared to C allele. Therefore, it was observed that more than 1.96, 1.97 and 1.56 fold increased risk of developing coronary artery disease. CONCLUSION: Our findings indicated that microRNA-423 CA genotype and A allele are associated with an increased susceptibility to Coronary artery disease. PMID- 30289087 TI - Verb-based prediction during language processing: the case of Dutch and Turkish. AB - This study investigated whether cross-linguistic differences affect semantic prediction. We assessed this by looking at two languages, Dutch and Turkish, that differ in word order and thus vary in how words come together to create sentence meaning. In an eye-tracking task, Dutch and Turkish four-year-olds (N = 40), five year-olds (N = 58), and adults (N = 40) were presented with a visual display containing two familiar objects (e.g., a cake and a tree). Participants heard semantically constraining (e.g., "The boy eats the big cake") or neutral sentences (e.g., "The boy sees the big cake") in their native language. The Dutch data revealed a prediction effect for children and adults; however, it was larger for the adults. The Turkish data revealed no prediction effect for the children but only for the adults. These findings reveal that experience with word order structures and/or automatization of language processing routines may lead to timecourse differences in semantic prediction. PMID- 30289086 TI - The Effects of D-aspartate in Neurosteroids, Neurosteroid Receptors, and Inflammatory Mediators in Experimental Autoimmune Encephalomyelitis. AB - OBJECTIVE: Experimental autoimmune encephalomyelitis (EAE) is a widely used model for multiple sclerosis. The present study has been designed to compare the efficiencies of oral and intraperitoneal (IP) administration of D-aspartate (D Asp) on the onset and severity of EAE, the production of neurosteroids, and the expression of neurosteroid receptors and inflammatory mediators in brain of EAE mice. METHODS: In this study, EAE was induced in C57BL/6 mice treated with D-Asp orally (D-Asp-Oral) or by IP injection (D-Asp-IP). On the 20th day, brains (cerebrums) and cerebellums of mice were evaluated by histological analyses. The brains of mice were analyzed for: 1) Neurosteroid (Progesterone, Testosterone, 17beta-estradiol) concentrations; 2) gene expressions of cytokines and neurosteroid receptors by reverse transcription polymerase chain reaction, and 3) quantitative determination of D-Asp using liquid chromatography-tandem mass spectrometry. Further, some inflammatory cytokines and matrix metalloproteinase-2 (MMP-2) were identified in the mouse serum using enzyme-linked immunosorbent assay kits. RESULTS: Our findings demonstrated that after D-Asp was administered, it was taken up and accumulated within the brain. Further, IP injection of D-Asp had more beneficial effects on EAE severity than oral gavage. The concentration of the testosterone and 17beta-estradiol in D-Asp-IP group was significantly higher than that of the control group. There were no significant differences in the gene expression of cytokine and neurosteroid receptors between control, D-Asp IP, and D-Asp-Oral groups. However, IP treatment with D-Asp significantly reduced C-C motif chemokine ligand 2 and MMP-2 serum levels compared to control mice. CONCLUSION: IP injection of D-Asp had more beneficial effects on EAE severity, neurosteroid induction and reduction of inflammatory mediators than oral gavage.

Literature regarding patterns of cerebrovascular injury (CVI) and outcomes among these patients is scarce. This is a descriptive study of the clinical profile, brain imaging findings, mechanisms of injury, vascular territory involvement and outcomes of CVI following scorpion and snake envenomation, in a tertiary care center in South India.MethodologyPatients with scorpion sting- and snake envenomation-related complications were retrospectively enrolled. Neuroimaging was performed on five patients with each envenomation, and they were found to have neurological involvement. On imaging, three patients were found to have a CVI. Clinical, radiological parameters and outcomes of these patients were studied. We also performed a review of the literature and analyzed the finding of all the cases.ResultIn all, three patients each had evidence of CVI in imaging. An additional 32 reports of scorpion sting-related CVI and 35 reports of snake envenomation-related CVI were identified from the literature. There was a male predominance among these patients. Mean age of the patients with scorpion sting was 42.8 years as compared with 33 years for the patients with snake envenomation. Features of severe envenomation were present in all patients. Persistently depressed sensorium and new-onset focal neurological deficits were seen in 70% of all patients. Infarcts were seen in 88% of patients with snake envenomation and 53% of patients with a scorpion sting. Mortality was 28% among patients with a scorpion sting as compared with 8% with snake envenomation. CONCLUSION: Cerebrovascular injuries are uncommon neurological manifestations following scorpion and snake envenomation. These tend to occur in younger patients. Infarcts are more common than bleeds.

AB - BACKGROUND: The role of panendoscopy in the modern investigation of head and neck cancer is changing with the development of improved radiological techniques, in office biopsy capabilities and the low rate of synchronous primary tumours. This study aimed to review the indications for panendoscopy in the investigation of newly diagnosed head and neck cancer. METHOD: A retrospective review was conducted of 186 patients with newly diagnosed head and neck cancer, between January 2014 and December 2015, at two tertiary centres. RESULTS: Obtaining a tissue diagnosis was the most common indication for panendoscopy (65 per cent), followed by surgical planning including transoral robotic surgery suitability assessment (22.6 per cent), and the investigation of carcinoma of an unknown primary (11.3 per cent). Two synchronous primary tumours were identified, generating a yield of 1.1 per cent. CONCLUSION: Panendoscopy remains integral in the assessment of transoral robotic surgery suitability. Refining indications for modern panendoscopy could reduce the need for this procedure in this cohort of patients. PMID- 30289090 TI - Added dietary cobalt or vitamin B12, or injecting vitamin B12 does not improve performance or indicators of ketosis in pre- and post-partum Holstein-Friesian dairy cows. AB - Vitamin B12 is synthesised in the rumen from cobalt (Co) and has a major role in metabolism in the peri-paturient period, although few studies have evaluated the effect of the dietary inclusion of Co, vitamin B12 or injecting vitamin B12 on the metabolism, health and performance of high yielding dairy cows. A total of 56 Holstein-Friesian dairy cows received one of four treatments from 8 weeks before calving to 8 weeks post-calving: C, no added Co; DC, additional 0.2 mg Co/kg dry matter (DM); DB, additional 0.68 mg vitamin B12/kg DM; IB, intra-muscular injection of vitamin B12 to supply 0.71 mg/cow per day prepartum and 1.42 mg/cow per day post-partum. The basal and lactation rations both contained 0.21 mg Co/kg DM. Cows were weighed and condition scored at drying off, 4 weeks before calving, within 24 h of calving and at 2, 4 and 8 weeks post-calving, with blood samples collected at drying off, 2 weeks pre-calving, calving and 2, 4 and 8 weeks post calving. Liver biopsy samples were collected from all animals at drying off and 4 weeks post-calving. Live weight changed with time, but there was no effect of treatment (P>0.05), whereas cows receiving IB had the lowest mean body condition score and DB the highest (P0.05) with mean values of 21.6 kg/day, 39.6 kg/day and 40.4 g/kg, respectively. Cows receiving IB had a higher plasma vitamin B12 concentration than those receiving any of the other treatments (P0.05) of treatment on homocysteine or succinate concentrations, although mean plasma methylmalonic acid concentrations were lower (P=0.019) for cows receiving IB than for Control cows. Plasma beta-hydroxybutyrate concentrations increased sharply at calving followed by a decline, but there was no effect of treatment. Similarly, there was no effect (P>0.05) of treatment on plasma non-esterified fatty acids or glucose. Whole tract digestibility of DM and fibre measured at week 7 of lactation were similar between treatments, and there was little effect of treatment on the milk fatty acid profile except for C15:0, which was lower in cows receiving DC than IB (P<0.05). It is concluded that a basal dietary concentration of 0.21 mg Co/kg DM is sufficient to meet the requirements of high yielding dairy cows during the transition period, and there is little benefit from additional Co or vitamin B12. PMID- 30289091 TI - Estimating the health and socioeconomic effects of cousin marriage in South Asia. AB - The effects of marriage between biological relatives on the incidence of childhood genetic illness and mortality are of major policy significance, as rates of consanguinity exceed 50% in various countries. Empirical research on this question is complicated by the fact that consanguinity is often correlated with poverty and other unobserved characteristics of households, which may have independent effects on mortality. This study has developed an instrumental variables empirical strategy to re-examine this question, based on the concept that the availability of unmarried cousins of the opposite gender at the time of marriage creates quasi-random variation in the propensity to marry consanguineously. Using primary data collected in Bangladesh in 2006-07 and Pakistan in 2009-10, the study found that previous estimates of the impact of consanguinity on child health were biased and falsely precise. The study also empirically investigated the social and economic causes of consanguinity (including marital quality) and concludes that marrying a cousin can have positive economic effects for one's natal family, by allowing deferral of dowry payments until after marriage. PMID- 30289092 TI - Ossicular chain mobilisation versus reconstruction in surgery for isolated malleus and/or incus fixation: systematic review and meta-analysis. AB - OBJECTIVE: To compare post-operative audiometric outcomes for the two prevailing surgical approaches for isolated malleus and/or incus fixation: ossicular mobilisation with preservation of the ossicular chain, and disruption and reconstruction of the ossicular chain. METHODS: A search was conducted, in December 2016, of PubMed, Scopus, and Cumulative Index to Nursing and Allied Health Literature articles written in English. Papers presenting original data regarding post-operative audiometric outcomes in patients who underwent surgical treatment for malleus and/or incus fixation with a mobile and intact stapes were included. A risk of bias assessment was performed on the 14 selected papers and a tier system was developed. Meta-analysis was accomplished by comparing pooled rates of surgical success by chi-square test and calculating odds ratios by logistical regression. Analysis was performed using Revman5 and R software.Results and conclusionAnalysis of the literature revealed no differences in audiometric outcomes between ossicular chain mobilisation and ossicular chain reconstruction in patients with isolated malleus and/or incus fixation. A large, prospective study comparing both short- and long-term hearing results for ossicular chain mobilisation and ossicular chain reconstruction in this population may identify whether a difference in outcomes exists between the two approaches. PMID- 30289093 TI - Neighborhood structural characteristics and Mexican-origin adolescents' development. AB - Ethnic-racial and socioeconomic residential segregation are endemic in the United States, representing societal-level sociocultural processes that likely shape development. Considered alongside communities' abilities to respond to external forces, like stratification, in ways that promote youth adaptive functioning and mitigate maladaptive functioning, it is likely that residence in segregated neighborhoods during adolescence has both costs and benefits. We examined the influences that early adolescents' neighborhood structural characteristics, including Latino concentration and concentrated poverty, had on a range of developmentally salient downstream outcomes (i.e., internalizing, externalizing, prosocial behaviors, and ethnic-racial identity resolution) via implications for intermediate aspects of adolescents' community participation and engagement (i.e., ethnic-racial identity exploration, ethnic-racial discrimination from peers, and school attachment). These mediational mechanisms were tested prospectively across three waves (Mage w1-w3 = 12.79, 15.83, 17.37 years, respectively) in a sample of 733 Mexican-origin adolescents (48.8% female). We found higher neighborhood Latino concentration during early adolescence predicted greater school attachment and ethnic-racial identity exploration and lower discrimination from peers in middle adolescence. These benefits, in turn, were associated with lower externalizing and internalizing and higher ethnic-racial identity resolution and prosocial behaviors in late adolescence. Findings are discussed relative to major guidelines for integrating culture into development and psychopathology. PMID- 30289094 TI - Development and implementation of an advance care planning program in Catalonia, Spain. AB - OBJECTIVE: Implementation of an advance care planning (ACP) program for people with advanced chronic conditions is a complex process. The aims of this paper are to describe (1) the development of the ACP program in Catalonia, Spain, for patients with advanced chronic conditions and complex needs and (2) the preliminary results of the implementation of this program in health and social services. METHOD: The ACP program was developed and implemented in a four-stage process as follows: (1) design and organization of the project; (2) selection of the professionals to carry out the project; (3) creation of four working groups to develop the conceptual model, guidelines, training program, and perform a qualitative evaluation; and (4) project implementation.ResultThe following deliverables were completed: (1) conceptual framework document; (2) practical guidelines for the application of the ACP; (3) online training course (3,763 healthcare professionals completed the online course, with an overall satisfaction rating of 8.4 on a 10-point scale); and (4) additional training activities (conferences, short courses, and seminars) in between 2015 and 2017.Significance of resultsThis project was led by the Catalan Ministry of Health. The strengths of the project development include the contribution of a wide range of professionals from the entire region, approval by the Catalan Bioethics Committee and the Social Services Ethics Committee, and the ongoing validation by members of the community. A standardized online training course was offered to all primary care professionals and included as a quality indicator for continuing education for those professionals in the period 2016-2020. The main outcome of this project is the establishment of a pragmatic ACP throughout the region and training of the health and social care professionals involved in the care of advanced chronic patients. PMID- 30289095 TI - Effect of adding heterologous versus homologous bovine seminal plasma prior to cryopreservation on bull sperm quality after thawing. AB - SummaryThe aim of this study was to investigate the effect of adding homologous or heterologous bovine seminal plasma (SP) to SP-free sperm samples before freezing on sperm quality after thawing. Ejaculates from bulls of known fertility were used as a source of SP. The SP was removed from further aliquots of the same ejaculates by colloid centrifugation to create SP-free sperm samples; the resuspended sperm pellets were treated with homologous or heterologous SP from high or low fertility bulls at 0%, 1% or 5% before freezing. After thawing, sperm quality was evaluated by computer-assisted sperm analysis and flow cytometry for membrane integrity, reactive oxygen species, chromatin structure, mitochondrial membrane potential and protein tyrosine phosphorylation. Data were analysed using Proc MIXED, SAS(r). Post-hoc comparisons were adjusted for multiplicity using Tukey's method. The addition of SP resulted in significant differences in sperm quality, namely velocity class A, Velocity Straight Line (VSL), Velocity Average Path (VAP), Velocity Curved Line (VCL), Amplitude of Lateral Head Displacement (ALH), Hyperactive (HYP), reactive oxygen species (ROS) production and % DNA fragmentation index (DFI) (P<0.05 for each). Although adding 5% homologous SP from high fertility bulls was beneficial to sperm kinematics, 5% heterologous SP from high fertility bulls had a deleterious effect on chromatin integrity and on sperm velocity. In conclusion, adding SP may have either a beneficial effect or a deleterious effect depending on the individuals involved. It might be feasible to use this method to improve sperm quality in some circumstances. PMID- 30289096 TI - Propensity in low-grade oocytes for delayed germinal vesicle breakdown compromises the developmental ability of sub-optimal grade Bubalus bubalis oocytes. AB - SummaryMaturing oocytes have diverse developmental potential and good quality oocytes exhibit a better ability to attain physiological milestones in a time dependent manner. This situation necessitates the confirmation of oocyte developmental status more precisely under an in vitro embryo production (IVEP) regime. The aim of this study was to explain timely events in germinal vesicle breakdown (GVBD), an important milestone of oocyte nuclear maturation, to delineate the developmental capacity of Bubalus bubalis oocytes. In addition, the expression profile of genes responsible for GVBD was assessed in order to understand the molecular context responsible for GVBD. The chronology of GVBD events at different time intervals during in vitro maturation (IVM) suggests that the rate at which oocytes undergo GVBD was strikingly different in the brilliant cresyl blue (BCB)+ and BCB- groups. The expression of AKT and CDC25B genes for BCB+ oocytes was maximum at 8 h of IVM, and CCNB (cyclin B) peaked at around 10 h, which suggested that GVBD was finished after 10 h in BCB+ oocytes, whereas the expression of AKT and CDC25B was found to peak at around 12-14 h of IVM. This difference consequently delays the GVBD event by 2-4 h in BCB- oocytes. Poor abundance of gene transcripts was mainly implicated in delay and lower rate of GVBD in BCB- oocytes which in turn strongly affected the translational ability of oocytes to blastocysts. The findings of this study support the idea that there is a propensity in sub-optimal grade oocytes for delayed GVBD that compromises the developmental ability of low grade buffalo oocytes. The study highlights the very small, but importantly vital and separate, time window of the GVBD event during which the competence levels of buffalo oocytes are altered along with their translational ability to develop into the prospective embryos.

Infographics are graphical illustrations of complex ideas that are broadly shared on social media platforms. What did this study ask? What is the effect of a social media strategy using infographics on the readership and dissemination of research articles? What did this study find? Infographic articles were associated with increased Altmetric scores and abstract views, but not full-text views. Why does this study matter to clinicians? The promotion of articles with infographics may increase awareness and dissemination of research findings among clinicians. PMID- 30289099 TI - Antioxidant and developmental capacity of retinol on the in vitro culture of rabbit embryos. AB - SummaryOxidative stress is a major cause of defective embryo development during in vitro culture. Retinoids are recognized as non-enzymatic antioxidants and may have an important role in the regulation of cell differentiation and vertebrate development. However, there are not enough reports discussing the antioxidant and developmental capacity of retinoids, including retinol (RT), on the in vitro development of embryos recovered from livestock animals, particularly in rabbit species. Therefore, morula embryos obtained from nulliparous Red Baladi rabbit does were cultured for 48 h in TCM199 medium in the absence of RT (control group) or in the presence of RT at concentrations of 10, 100 and 1000 nM. The developmental capacity to the hatched blastocyst stage, the antioxidant biomarker assay and the expression of several selected genes were analyzed in each RT group. The data show that RT significantly (P<0.001) promoted the embryo hatchability rate at the concentration of 1000 nM to 69.44% versus 29.71% for the control. The activity of malondialdehyde (MDA) level was significantly (P<0.05) lower in the RT groups than in the control group, while the total antioxidant capacity (TAC), superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities were significantly (P<0.05) higher following treatment with RT. Furthermore, RT treatment considerably upregulated the relative expression of gap junction protein alpha 1 (GJA1), POU class 5 homeobox 1 (POU5F1) and superoxide dismutase 1 (SOD1) genes compared with the control group. The current study highlights the potential effects of RT as antioxidant in the culture medium on the in vitro development of rabbit embryos. PMID- 30289100 TI - Changes in body composition and meat quality in response to dietary amino acid provision in finishing broilers. AB - In order to control and optimize chicken quality products, it is necessary to improve the description of the responses to dietary amino acid (AA) concentration in terms of carcass composition and meat quality, especially during the finishing period. The aim of this study was to investigate the effects of Lysine (Lys, i.e. a limiting AA used as reference in AA nutrition) and AA other than Lys (AA effect). In total, 12 experimental diets were formulated with four levels of digestible Lys content (7, 8.5, 10 and 11.5 g/kg) combined with either a low (AA ), adequate control (AAc) and high (AA+) amount of other essential AA (EAA) expressed as a proportion of Lys. They were distributed to male Ross PM3 from 3 to 5 weeks of age. No significant AA*Lys interaction was found for growth performance or carcass composition. Body weight and feed conversion ratio were significantly improved by addition of Lys but were impaired in broilers receiving the AA- diets, whereas breast meat yield and abdominal fat were only affected by Lys. No additional benefit was found when the relative amount of other EAA was increased. There was a significant AA*Lys interaction on most of the meat quality traits, including ultimate pH, color and drip loss, with a significant effect of both AA and Lys. For example, AA- combined with reduced Lys level favored the production of meat with high ultimate pH (>6.0), dark color and low drip loss whereas more acid, light and exudative meat (<5.85) was produced with AA+ combined with a low Lys level. In conclusion, growth performance, carcass composition and meat quality are affected by the levels of dietary Lys and AA in finishing broilers. In addition, interactive responses to Lys and AA are found on meat quality traits, leading to great variations in breast pHu, color and drip loss according AA balance or imbalance. PMID- 30289101 TI - Pumilio1 phosphorylation precedes translational activation of its target mRNA in zebrafish oocytes. AB - SummaryTranslational regulation of mRNAs is crucial for promoting various cellular and developmental processes. Pumilio1 (Pum1) has been shown to play key roles in translational regulation of target mRNAs in many systems of diverse organisms. In zebrafish immature oocytes, Pum1 was shown to bind to cyclin B1 mRNA and promote the formation of cyclin B1 RNA granules. This Pum1-mediated RNA granule formation seemed critical to determine the timing of translational activation of cyclin B1 mRNA during oocyte maturation, leading to activation of maturation/M-phase-promoting factor (MPF) at the appropriate timing. Despite its fundamental importance, the mechanisms of translational regulation by Pum1 remain elusive. In this study, we examined the phosphorylation of Pum1 as a first step to understand the mechanisms of Pum1-mediated translation. SDS-PAGE analyses and phosphatase treatments showed that Pum1 was phosphorylated at multiple sites during oocyte maturation. This phosphorylation began in an early period after induction of oocyte maturation, which preceded the polyadenylation of cyclin B1 mRNA. Interestingly, depolymerization of actin filaments in immature oocytes caused phosphorylation of Pum1, disassembly of cyclin B1 RNA granules, and polyadenylation of cyclin B1 mRNA but not translational activation of the mRNA. Overexpression of the Pum1 N-terminus prevented the phosphorylation of Pum1, disassembly of cyclin B1 RNA granules, and translational activation of the mRNA even after induction of oocyte maturation. These results suggest that Pum1 phosphorylation in the early period of oocyte maturation is one of the key processes for promoting the disassembly of cyclin B1 RNA granules and translational activation of target mRNA.

AB - SummaryThe objectives were to develop an effective protocol for transfection of ovine secondary follicles and to assess the effect of attenuating aquaporin 3 (AQP3) using a small interfering RNA (siRNA-AQP3) on antrum formation and follicular growth in vitro. Various combinations of Lipofectamine(r) volumes (0.5, 0.75 or 1.0 ul), fluorescent oligonucleotide (BLOCK-iT TM) concentrations (3.18, 27.12 or 36.16 nM) and exposure times (12, 14, 16, 18 or 20 h) were tested. The BLOCK-iTTM was replaced by siRNA-AQP3 in the transfection complex. Ovine secondary follicles were isolated and cultured in vitro for 6 days using standard protocols. Follicles were transfected on day 0 or 3 or on both days (0 and 3) and then cultured for an additional 3 or 6 days. As revealed by the fluorescence signal, the Lipofectamine(r)/BLOCK-iTTM complex (0.75 ul + 27.12 nM by 12 h of incubation) crossed the basement membrane and granulosa cell and reached the oocytes. In general, the rate of intact follicles was higher and the rate of antrum formation was lower in transfected follicles compared with control follicles. In conclusion, ovine secondary follicles can be successfully transfected during in vitro culture, and siRNA-mediated attenuation of AQP3 gene reduced antrum formation of secondary follicles. PMID- 30289104 TI - Wound healing after tonsillectomy - a review of the literature. AB - OBJECTIVE: To summarise the available literature related to wound healing post tonsillectomy, including the stages of healing, experimental models for assessing healing (in animals and humans) and the various factors that affect wound healing. METHODS: A search of the English literature was conducted using the Ovid Medline database, with the search terms 'tonsillectomy' or 'tonsil' and 'wound healing'. Thirty-one articles that objectively assessed tonsillectomy wound healing were included for analysis. RESULTS: The majority of assessments in humans investigating tonsillectomy wound healing involve serial direct clinical examinations of the oral cavity. Many patient and surgical factors have been shown to affect wound healing after tonsillectomy. There is some research to suggest that the administration of adjunctive treatment in the post-operative period may be beneficial to tonsillectomy wound healing. CONCLUSION: Wound healing post tonsillectomy has been poorly researched. Having a better understanding of the process of wound healing would allow surgeons to potentially prevent, anticipate and manage complications from the surgery that arise as part of the healing process. PMID- 30289105 TI - Awareness of High Blood Pressure by Nativity Among Black Men: Implications for Interpreting the Immigrant Health Paradox. AB - INTRODUCTION: Differences in the social determinants of health and cardiovascular health outcomes by nativity have implications for understanding the immigrant health paradox among black immigrants. We aimed to understand whether blood pressure awareness, a precursor to achieving blood pressure control among hypertensive patients, varied by nativity among a sample of black men. METHODS: Data were collected from 2010 through 2014. In 2016, we conducted logistic regression models using data from a large sample of urban-dwelling middle-aged and older black men. All men in the study had measured high blood pressure at the time of enrollment and were also asked whether they were aware of having high blood pressure. Independent variables included demographics, socioeconomic status, access to care, and health-related behaviors. RESULTS: Foreign-born participants were significantly less likely than US-born participants to report awareness of having high blood pressure (P < .001). We observed a significant positive relationship between proportion of life spent in the US and being aware of having hypertension (beta = 0.863; 95% CI, 0.412-1.314; P < .001). This relationship remained after adjusting the model for salient independent variables (beta = 0.337; 95% CI, 0.041-0.634; P = .03). CONCLUSIONS: Difference in hypertension awareness by nativity may skew surveillance estimates used to track health disparities by large heterogeneous racial categories. Our results also indicate that prior health care experience and circumstances should be considered when studying the immigrant health paradox. PMID- 30289106 TI - Inpatient Medicaid Usage and Expenditure Patterns After Changes in Supplemental Nutrition Assistance Program Benefit Levels. AB - INTRODUCTION: Food insecurity worsens health outcomes and is associated with increased health care usage and expenditures. The Supplemental Nutrition Assistance Program (SNAP) reduces but does not eliminate recipients' food insecurity. We sought to determine whether inpatient Medicaid usage and expenditure patterns responded to an April 2009 increase in SNAP benefit levels and a subsequent November 2013 decrease. METHODS: Interrupted time series models estimated responses to the 2009 and 2013 SNAP changes in the Medicaid population, compared responses between Medicaid and Medicare recipients, and compared responses between Medicaid recipients with different likelihoods of having a disability. Analyses used 2006 through 2014 Healthcare Cost and Utilization Project National (previously Nationwide) Inpatient Sample data. RESULTS: After the 2009 SNAP increase, Medicaid admission growth fell nationally from 0.80 to 0.35 percentage points per month (a difference of -0.45; 95% CI, -0.72 to -0.19), adjusting for enrollment. After the 2013 SNAP decrease, admission growth rose to 2.42 percentage points per month (a difference of 2.07; 95% CI, 0.68 to 3.46). Inflation-adjusted monthly Medicaid expenditures followed similar patterns and were associated with $26.5 billion (in 2006 dollars) in reduced expenditures over the 55 months of the SNAP increase, and $6.4 billion (in 2006 dollars) in additional expenditures over the first 14 months after the SNAP decrease. Effects were elevated for Medicaid compared with Medicare recipients and among people with a high likelihood of having a disability. CONCLUSION: Although alternative causal explanations warrant consideration, changes in SNAP benefit levels were associated with changes in inpatient Medicaid usage and cost patterns.

How to predict prostate cancer progression at the time of diagnosis remains challenging. OBJECTIVE: To identify single nucleotide polymorphisms (SNPs) associated with death from prostate cancer. DESIGN, SETTING, AND PARTICIPANTS: Blood samples from 11 506 men in Sweden were collected during 1991-1996. Of these, 1053 men were diagnosed with prostate cancer and 245 died from the disease. Stage and grade at diagnosis and outcome information were obtained, and DNA from all cases was genotyped. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: A total of 6 126 633 SNPs were tested for association with prostate-cancer-specific survival time using a Cox proportional hazard model, adjusted for age, stage, and grade at diagnosis. A value of 1*10-6 was used as suggestive significance threshold. Positive candidate SNPs were tested for association with gene expression using expression quantitative trait locus analysis. RESULTS AND LIMITATIONS: We found 12 SNPs at seven independent loci associated with prostate-cancer-specific survival time. One of 6 126 633 SNPs tested reached genome-wide significance (p<5*10-8) and replicated in an independent cohort: rs73055188 (p=5.27*10-9, per allele hazard ratio [HR]=2.27, 95% confidence interval [CI] 1.72-2.98) in the AOX1 gene. A second SNP reached a suggestive level of significance (p<1*10-6) and replicated in an independent cohort: rs2702185 (p=7.1*10-7, per-allele HR=2.55, 95% CI=1.76-3.69) in the SMG7 gene. The SNP rs73055188 is correlated with AOX1 expression levels, which is associated with biochemical recurrence of prostate cancer in independent cohorts. This association is yet to be validated in other ethnic groups. CONCLUSIONS: The SNP rs73055188 at the AOX1 locus is associated with prostate-cancer-specific survival time, and AOX1 gene expression level is correlated with biochemical recurrence of prostate cancer. PATIENT SUMMARY: We identify two genetic markers that are associated with prostate-cancer-specific survival time. PMID- 30289110 TI - Endobronchial ultrasound: Echoing in the field of pediatrics. AB - Endobronchial ultrasound (EBUS) is a useful technique for the diagnosis and staging of the lung and mediastinal lesions, which is crucial for selecting treatment protocol. Under EBUS guidance, transbronchial needle aspiration (TBNA) is widely applied for obtaining specimens for histological, cytological, and molecular evaluation. Recently, the EBUS scope designed for adults has been used in large pediatric candidates. The presence of lung masses and mediastinal lymphadenopathy in the pediatric population presents a diagnostic challenge; however, EBUS is a promising tool for pediatricians to address these challenging issues. In some centers, the adult EBUS echobronchoscope is applied in transesophageal procedures for pediatric patients. EBUS-guided TBNA can also be used to perform minimally invasive interventional therapy, such as fiducial marker placement for assisting precision radiation, brachytherapy, and radiofrequency ablation therapy. With the development of EBUS equipment designed specifically for children, pediatric EBUS will play an increasingly important role.

AB - Scleredema adultorum of Buschke is a rare fibromucinous, scleroderma-like connective tissue disease most commonly found in a post-infectious setting or linked to hematological disorders or diabetes. Lichen sclerosus et atrophicus is an autoimmune condition only in 2.5% of cases localized exclusively at an extragenital site, occurring in up to 34% of patients in association with other autoimmune diseases such as vitiligo, thyroid disorders, alopecia areata, lichen planus, morphea, pernicious anemia and systemic lupus erythematosus. In particular, a stronger link with an autoimmune background in lichen sclerosus et atrophicus has been observed in women who showed higher prevalence for autoimmune conditions and circulating autoantibodies. Literature reveals a genetic susceptibility linked to specific HLA types. We report three patients who developed lichen sclerosus et atrophicus superimposed on skin involved by scleredema adultorum of Buschke. Although the association of lichen sclerosus et atrophicus with scleredema adultorum of Buschke could be coincidental, both diseases could be considered part of the spectrum of sclerodermoid disorders with common underlying pathogenetic mechanisms; which could explain the sequential or simultaneous occurrence of both lesions in our patients.

PMID- 30289123 TI - Clinical Effectiveness of Er: YAG Lasers Adjunct to Scaling and Root Planing in Non-Surgical Treatment of Chronic Periodontitis: A Meta-Analysis of Randomized Controlled Trials. AB - BACKGROUND Er: YAG lasers (ERLs) show suitable characteristics for scaling and root planing, but previous studies have drawn conflicting conclusions. This meta analysis aimed to systematically appraise the available evidence concerning the effectiveness of ERLs as an adjunct to scaling and root planing (SRP) for non surgical periodontal treatment. MATERIAL AND METHODS Randomized controlled trials (RCTs) comparing ERLs+SRP with SRP alone for the treatment of chronic periodontitis were searched in 9 electronic biomedical databases up to January 2018. The weighted mean differences (WMDs) and 95% confidence intervals (CIs) were counted for probing depth (PD) reduction, clinical attachment level (CAL) gain, and visual analog scale (VAS) score. Heterogeneity was evaluated with the I2 statistic for interstudy comparisons and the chi2-based Q statistic for intra study comparisons. Sensitivity analysis was conducted by switching to a random or fixed effect model based on the heterogeneity. Publication bias was measured by Begg's test. RESULTS Ten related RCTs met the inclusion criteria. There were statistically significant differences in the assessed clinical parameters at the three-month follow-up: PD reduction (WMD=0.32, 95%CI range from 0.14 to 0.51, p<0.001; p=0.003, I2=69.7%); CAL gain (WMD=0.31, 95%CI range from 0.22 to 0.40, p<0.001; p=0.209, I2=28.8%); and VAS scores (WMD=-1.38, 95%CI range from -2.45 to -0.31, p<0.001; p=0.182, I2=44%). There were no significant differences at the six- and twelve-month follow-ups. Sensitivity analysis revealed that the results were consistent. No evidence of publication bias was detected. CONCLUSIONS This systematic analysis demonstrated that ERLs+SRP provides additional short-term effectiveness and that patients experience less pain compared to SRP. There were no significant differences at the medium-term and long-term follow-ups. Long-term well-designed RCTs are required. PMID- 30289125 TI - Determinants of preterm birth at Jimma University Medical Center, southwest Ethiopia. AB - Background: Preterm birth is the second leading cause of death next to pneumonia in children aged <5 years and the single-most important cause of death in the first month of life. Research examining determinants of preterm birth in Ethiopia is limited. Therefore, this study aimed to determine risk factors associated with preterm births at Jimma University Medical Center in southwest Ethiopia. Methods: This unmatched case-control study was conducted from March 15 to April 1, 2017 from medical records of mothers and newborns delivered at Jimma University Medical Center from January 1 to December 30, 2016. Data were extracted using a structured checklist for cases (preterm) and controls (term) by reviewing maternal and newborn medical records using a simple random-sampling technique. Risk factors for preterm delivery were determined using bivariate and multivariate logistic regression models. Statistically significant associations were declared at P<0.05. Results: The present study evaluated 218 maternal and newborn cases and 438 controls. Risk factors identified were history of previous preterm birth (AOR 6.4, 95% CI 2.9-13.9), preeclampsia (AOR 6.6, 95% CI 3.3 13.4), premature membrane rupture (AOR 11.7, 95% CI 6.2-21.9), antenatal care of fewer than four visits (AOR 4.8, 95% CI 1.2-19), birth interval <2 years (AOR 2.7, 95% CI 1.7-4.5), and multiple pregnancies (AOR 4.5, 95% CI 2.4-8.5). Conclusion: History of previous preterm births, preeclampsia, premature membrane rapture, antenatal care of fewer than four visits, birth interval <2 years, and multiple pregnancies were found to have a possible causal relationship with preterm births. Therefore, similar further studies should be conducted to generate more population-based evidence on determinants of preterm births.

AB - To obtain truly informed consent, we must be able to advise our patients accurately about the relative risk and benefit of any treatment plan. Percutaneous renal biopsy remains the gold standard investigation in the evaluation of intrinsic renal disease. There have been significant improvements in practice over the past decades with regards to percutaneous renal biopsy. Across centres, we appear now to have reached agreement on many aspects of this procedure, such as the need for blood pressure control, avoidance of coagulopathy, use of spring-loaded needles under direct imaging guidance and a need to monitor for complications. The authors from Rush University Medical Centre provide reassurance that renal biopsy in the modern era remains a safe procedure with a low rate of significant bleeding. There remain areas of divergence in practice that may have unintended and deleterious consequences: administration of desmopressin and discontinuation of aspirin, for example, both carry a risk of thrombosis. It is our opinion that it is time to reach consensus on our interpretation of the available data and to draw up guidelines to standardize our biopsy practice internationally. PMID- 30289129 TI - Risk of percutaneous renal biopsy of native kidneys in the evaluation of acute kidney injury. AB - Background: Percutaneous renal biopsy (PRB) of native kidneys (NKs) to better understand and treat acute kidney injury (AKI) is being advocated, but little is known about the risk of complications. Methods: We performed a retrospective study of PRB of NKs in 955 adults from 1991 to 2015 at an academic medical center with real-time ultrasound and automated biopsy needles. Patients undergoing PRB for evaluation of AKI (n = 160) were compared with 795 patients biopsied for other reasons (not-AKI) for postbiopsy complications [need for transfusion of packed red blood cells (PRBCs), an interventional radiologic or surgical procedure, readmission or death]. Results: Patients biopsied for AKI were older (58 +/- 16 versus 44 +/- 16 years; P < 0.0001), with a higher serum creatinine (SCr) (4.5 +/- 2.7 versus 1.8 +/- 1.6 mg/dL; P < 0.0001) and lower hemoglobin (Hgb) (10.4 +/- 1.7 versus 12.1 +/- 2.1; P < 0.0001) and a greater proportion had an abnormal bleeding time (12.5% versus 7.4%, P 0.04), partial thromboplastin time (15.2% versus 5.3%, P < 0.0001) and/or prothrombin time (27.0% versus 12.8%; P < 0.0001) compared with not-AKI patients. Complications post-PRB were significantly greater in patients biopsied for AKI {11.3% versus 6.7%; P=0.04; odds ratio [OR] 1.78 [95% confidence interval (CI) 1.01-3.12]} with patients biopsied for AKI requiring more blood transfusions (10.0% versus 5.3%; P 0.02; OR 2.04 (95% CI 1.12-3.74)]. By multivariate analysis, baseline features predictive of a complication were increased SCr and decreased Hgb level, as well as female gender and increased systolic blood pressure. Conclusion: Patients biopsied for evaluation of AKI are at greater risk of complications due to increased risk factors. PMID- 30289130 TI - Comparison of native and transplant kidney biopsies: diagnostic yield and complications. AB - Background: The safety and adequacy are established for the native percutaneous renal biopsy (PRB) but no prospective studies exist that directly compare these with transplant PRB. Methods: From 1995 to 2015, 1705 adults underwent percutaneous native [native renal biopsy (NRB)] or transplant renal biopsy (TRB) by the Nephrology service. Real-time ultrasound and automated biopsy needles (NRB, 14 or 16 gauge; TRB, 16 gauge) were used. Patients were observed for 24 h (NRB) or 8 h (TRB) post-procedure. Adequacy was defined as tissue required for diagnosis plus glomerular yield. Complications were defined as those resulting in the need for an intervention, such as surgery, interventional radiologic procedure, readmission, blood transfusion and death. Data were collected prospectively in all biopsies. Results: At the time of biopsy, NRB patients were younger (mean +/- SD, 47 +/- 17 versus 50 +/- 14 years, P < 0.0001) and more often female (62 versus 48%, P < 0.0001) compared with TRB. A fellow supervised by an attending performed the procedure in 91% of NRB compared with 63% of TRB (P < 0.0001). TRB patients were more hypertensive [systolic blood pressure (SBP) 140 +/- 22 versus 133 +/- 18 mmHg, P < 0.0001] and had a higher serum creatinine (3.1 +/- 1.8 versus 2.3 +/- 2.2 mg/dL, P < 0.0001), activated partial thromboplastin time (28 +/- 4.3 versus 27 +/- 5 s, P < 0.0001) as well as lower hemoglobin (Hgb) (11.2 +/- 1.8 versus 11.7 +/- 2.1 g/dL, P < 0.0001) compared with NRB. Adequate tissue for diagnosis was obtained in > 99% of NRB and TRB (P = 0.71). Compared with TRB, NRB had a greater drop in Hgb after the biopsy (0.97 +/- 1.1 versus 0.73 +/- 1.3 g/dL, P < 0.0001), a higher complication rate (6.5 versus 3.9%, P = 0.02) and higher transfusion rate (5.2 versus 3.3%, P = 0.045). There was one death in each group attributed to the biopsy. Conclusions: Although death is equally rare, the complication rate is higher in NRB compared with TRB despite TRB having more of the traditional risk factors for bleeding. Differences in technique, operator (fellow or attending) or needle gauge may explain this variability. PMID- 30289131 TI - Unravelling drug-induced hypertension: molecular mechanisms of aldosterone independent mineralocorticoid receptor activation by posaconazole. AB - Drug-induced hypertension offers the opportunity to further understand pathways involved in the regulation of blood pressure. Posaconazole is an antifungal agent known to induce hypertension and hypokalaemia. In recent months, a flurry of reports has unravelled the metabolic processes involved. In this issue of CKJ, Barton K, Davis TK, Marshall B et al. Posaconazole-induced hypertension and hypokalemia due to inhibition of the 11beta-hydroxylase enzyme. Clin Kidney J 2018; 11: 691-693 present convincing evidence of 11beta-hydroxylase inhibition resulting in a biochemical syndrome resembling genetic congenital adrenal hyperplasia and characterized by high 11-deoxycorticosterone and 11-deoxycortisol levels as well as androgen levels. This adds to prior evidence supporting inhibition of 11beta-hydroxysteroid dehydrogenase 2, the enzyme that inactivates cortisol in aldosterone-sensitive tissues such as the kidneys, yielding a syndrome resembling genetic apparent mineralocorticoid excess or licorice toxicity, characterized by a high cortisol/cortisone ratio. PMID- 30289132 TI - Posaconazole-induced hypertension and hypokalemia due to inhibition of the 11beta hydroxylase enzyme. AB - Posaconazole is an antifungal therapy reported to cause incident hypertension. Hypokalemia is also a known side effect. The combination of hypertension and hypokalemia suggests mineralocorticoid excess. We present the case of a 15-year old adolescent male with hypertensive urgency while on prophylactic posaconazole therapy for a combined immunodeficiency. We identify the mechanism of posaconazole-induced hypertension to be inhibition of the 11beta-hydroxylase enzyme, resulting in elevated levels of the mineralocorticoid receptor activator deoxycorticosterone. Loss of function of the 11beta-hydroxylase enzyme is responsible for a rare form of congenital adrenal hyperplasia and can be associated with life-threatening adrenal crisis. PMID- 30289133 TI - Assessing the capability of in silico mutation protocols for predicting the finite temperature conformation of amino acids. AB - Mutation protocols are a key tool in computational biophysics for modelling unknown side chain conformations. In particular, these protocols are used to generate the starting structures for molecular dynamics simulations. The accuracy of the initial side chain and backbone placement is crucial to obtain a stable and quickly converging simulation. In this work, we assessed the performance of several mutation protocols in predicting the most probable conformer observed in finite temperature molecular dynamics simulations for a set of protein-peptide crystals differing only by single-point mutations in the peptide sequence. Our results show that several programs which predict well the crystal conformations fail to predict the most probable finite temperature configuration. Methods relying on backbone-dependent rotamer libraries have, in general, a better performance, but even the best protocol fails in predicting approximately 30% of the mutations. PMID- 30289134 TI - Fluorescence response from the surface states of nitrogen-doped carbon nanodots: evidence of a heterogeneous population of molecular-sized fluorophores. AB - Fluorescent Nitrogen-doped Carbon Nanodots (NCDs) of ~4 nm diameter were prepared by acid-driven microwave irradiation of DMF solvent. Spectroscopic studies of the NCDs demonstrated that excitation of the carbon core did not contribute any fluorescence emission. Instead, the emission originated exclusively from the surface states. The fluorescence featured a prominent red edge excitation shift (REES), while changing the excitation wavelength over ~0.5 eV indicated the emergence of different emitter species in the temporal evolution of fluorescence. These results combined to indicate a large degree of heterogeneity in the population of these surface-localized emitters, so that working with different excitation energies produced different sets of excited surface fluorophores that evolved independently of each other. Fluorescence anisotropy dynamics in the NCDs was attributable to the reorientational motion of the surface fluorophores which was decoupled from the rotational diffusion of the carbon core of the NCD. The anisotropy decay rates revealed that the fluorophores had size comparable to typical organic fluorophores, irrespective of excitation energy. PMID- 30289135 TI - Unveiling CO adsorption on Cu surfaces: new insights from molecular orbital principles. AB - CO adsorption on Cu(100), (110), and (111) surfaces has been extensively studied using Kohn-Sham density functional theory calculations. A holistic analysis of adsorption energies, charge transfer, and structural changes has been employed to highlight the variations in adsorption mechanisms upon changing the surface type and the adsorption site. Each surface, with its unique arrangement of atoms, resulted in a varying adsorbate behavior, although the same adsorption site is considered. This directly reflects the influence of the atomic arrangement on the substrate-adsorbate interactions. Site-interactions are rigorously investigated using molecular-orbital and charge transfer principles taking into account the fundamental interaction of frontier (5sigma and 2pi*) orbitals. Considering the effects of the surface atomic arrangement and density of metal interacting orbitals, along with the relative d-5sigma and d-2pi* energy spacings, the calculated adsorption preference to higher coordination sites is explained, which also revealed valuable interpretations to the well-known DFT CO adsorption puzzle. In addition, we studied the perturbations occurring upon adsorption to the 3sigma and 1pi orbitals, which hold the internal C-O bond. Studying 3sigma and 1pi orbital perturbations provided a wealth of theoretical interpretations for the varying behavior of the adsorbate molecule when similar adsorption sites are compared at different facets.

AB - As an adsorbent of gaseous ammonia, cobalt hexacyanocobaltate (CoII3[CoIII(CN)6]2) was proved to have good sorption even at high temperatures, with thermal recyclability in sorption-desorption cycles. The maximum sorption capacities evaluated with a dual-site Langmuir model are 25.2, 18.6, 8.6, and 2.1 mmol g-1 at 20, 100, 150, and 250 degrees C, respectively.

Its superior sensing performance and practical applications were well demonstrated. PMID- 30289139 TI - Geometric deconstruction of core and electron activation of a pi-system in a series of deformed porphyrins: mimics of heme. AB - The predominant distortion of heme is responsible for its electronic activity, catalytic ability and spectral properties. In this work, altogether 12 new X-ray structures of saddled, waved and ruffled porphyrins are reported. Three types of deformed porphyrins as mimics of heme were evaluated and analyzed by geometric deconstruction, spectral comparison, and electrochemical tracking, which shows a unique relationship of deformation fashions and distortion degree to the geometry of the core and electron transfer ability of rings in these enzyme containing porphyrins. These mimics can adjust their core geometry for changing the structures of potential metals; while for rings themselves, they can also regulate the electron activity by switching the HOMO of the large pi systems. These deformed porphyrins can be used as ideal mimics for heme. These findings help us to understand the principle and contribution of these deformations to electron transfer in catalytic oxidation and photoreactions. The nonplanar mimics have been synthesized through a modular synthetic approach under Adler-Longo or Lindsey condensation conditions. PMID- 30289140 TI - Trigonal layered rosiaite-related antiferromagnet MnSnTeO6: ion-exchange preparation, structure and magnetic properties. AB - Ion-exchange treatment of Na2SnTeO6 in molten salt mixtures resulted in rosiaite (PbSb2O6)-related MnSnTeO6. Its crystal structure was refined by the Rietveld method. Of the three possible models of Sn/Te distribution, the disordered model (P3[combining macron]1m, a = 5.23093(11) A, c = 4.62430(16) A) was preferred based on bond distances. However, it is supposed that each individual (SnTeO6)2- layer retains complete ordering of the precursor and the apparent disorder is only due to stacking faults. Magnetic studies have shown that MnSnTeO6 orders antiferromagnetically at Neel temperature TN = 9.8 K. The effective magnetic moment reasonably agrees with theoretical estimations assuming high-spin configuration of Mn2+ (S = 5/2). Electron spin resonance reveals spin dynamics in accordance with antiferromagnetic ordering. Moreover, critical broadening of ESR linewidth indicates the low-dimensional type of exchange interactions. Based on the temperature and field-dependent magnetization studies, the magnetic phase diagram of the new compound was constructed. PMID- 30289141 TI - Light-induced morphological transition between unconjugated bilirubin photoisomers. AB - Morphology switching by an external stimulus creates the possibility to detect and control the activity and functionality of bio-molecules. Unconjugated bilirubin (UCB), a waste product resulting from heme catabolism, is highly sensitive towards blue light induced configurational conversion from (4Z,15Z) to (4Z,15E)-bilirubin. UCB has a distinct elongated nanostructure which is readily photoswitchable to spherical by external blue light (470 nm) irradiation. Herein, the morphology alteration by blue light was nicely correlated with the photoisomerisation of UCB, using different microscopic and spectroscopic techniques. To restrict the other photo-incidents during phototreatment on UCB, a suitable time frame was calibrated by monitoring the absorption, HPLC, lifetime distribution and 1H NMR studies. Furthermore, by the help of this morphological transition as a marker, UCB early stage photoisomerisation has also been triggered by two-photon irradiation (940 nm).

PMID- 30289143 TI - Dual purpose fibre - SERS pH sensing and bacterial analysis. AB - The exploitation of fibre based Raman probes has been challenged by often complicated fabrication procedures and difficulties in reproducibility. Here, we have demonstrated a simple and cost-effective approach for sensing pH through an optical fibre, by employing a wax patterned filter paper-based substrate for surface enhanced Raman spectroscopy (SERS). Through this method, high reproducibility between fibres was achieved. In addition to sensing pH, it was possible to extract fluid samples containing P. aeruginosa for further analysis. This dual purpose fibre is bronchoscope deployable, and is able to gather information about both the host and pathogen, which may lead to an improved treatment plan in future in vivo applications. PMID- 30289144 TI - A highly hydrolytically stable lanthanide organic framework as a sensitive luminescent probe for DBP and chlorpyrifos detection. AB - Organic pollutants have attracted increasing attention due to their strong persistence and extensive diffusivity. Plasticizers (PAEs) and organophosphorus pesticides (OPs), as the vital part of organic pollutants, have made extensive damage to the environment with the rapid development of modern agriculture and industry. Therefore, we have, for the first time, carried out a quantitative analysis of the PAEs and OPs by fluorescence recognition. A series of isostructural lanthanide organic frameworks, [Ln(tftpa)1.5(2,2'-bpy)(H2O)] (Ln = Gd 1, Eu 2 and Tb 3, H2tftpa = tetrafluoroterephthalic acid), were hydrothermally synthesized, of which 3 exhibited excellent hydrolytic resistance to both boiling acidic and basic aqueous solutions. Moreover, luminescence investigations show that 3 can be used as a highly sensitive and recyclable luminescence sensor for the detection of DBP (di-n-butyl phthalate) in simulated seawater and chlorpyrifos in ethanol with the detection limits of 2.07 and 0.14 ppb, respectively.

AB - Nowadays, agglomeration and leaching of metal active sites during reaction and recycle processes are considered to be a thorny problem for noble metal-based catalysts. Therefore, to make improvements, nano-gold was selected as a representative research object for many noble metals. In this study, Au nanoparticles (NPs) and magnetic gamma-Fe2O3 were intercalated in situ in the walls of MCM-41 via a one-pot hydrothermal method, in which the intercalation process was preceded by co-condensation of tetraethyl orthosilicate (TEOS) with MPTS-Au complexes ((3-mercaptopropyl)-trimethoxysilane (MPTS), HAuCl4.3H2O), and a Fe3O4 sol. By the confinement of silica, Au NPs and gamma-Fe2O3 were well dispersed in the walls of MCM-41, the sintering and loss of Au NPs was highly restricted, and the magnetic property of gamma-Fe2O3 facilitated the recycling of Au-based catalysts. Additionally, abundant void defects appeared in MCM-41 by assembly of micelles in different sizes and shapes, greatly improving the surface area of target catalysts (>1800 m2 g-1), which provided more opportunities for contact and collision between reactors and gold active sites, effectively solving the problem of mass transportation. As expected, a series FeAu@MCM-41 catalysts showed superior catalytic activity in the reduction of 4-nitrophenol (4-NP) and organic dyes (MB, RhB, and MO), and these catalysts were recycled five times without significant loss of metal species or catalytic activity. This is attributed to the confinement effect of the silica walls and the excellent magnetic properties of gamma-Fe2O3. This special structure of FeAu@MCM-41 catalysts provides more insights for designing and fabricating noble metal-based catalysts with desirable performances.

AB - A highly rigid spiro phosphine-oxazoline ligand skeleton with a spirocarbon stereogenic center was developed from 7-bromo-1-indanone. The catalytic performance of the ligand was demonstrated in palladium-catalyzed asymmetric allylic alkylation. Under optimized conditions, high yields (up to 99%) and enantioselectivities (up to 99.9% ee) were obtained for reactions of 1,3 diphenylallyl acetates and symmetrical 1,3-dicarbonyl substrates. PMID- 30289147 TI - An integrated microfluidic/microelectrode array for the study of activity dependent intracellular dynamics in neuronal networks. AB - In the central nervous system, neurons are organized in specific neural networks with distinct electrical patterns, input integration capacities, and intracellular dynamics. In order to better understand how neurons process information, it is crucial to keep the complex organization of brain circuits. However, performing subcellular investigations with high spatial and temporal resolution in vivo is technically challenging, especially in fine structures, such as axonal projections. Here, we present an on-a-chip system that combines a microfluidic platform with a dedicated matrix of electrodes to study activity dependent dynamics in the physiological context of brain circuits. Because this system is compatible with high-resolution video-microscopy, it is possible to simultaneously record intracellular dynamics and electrical activity in presynaptic axonal projections and in their postsynaptic neuronal targets. Similarly, specific patterns of electrical activity can be applied to both compartments in order to investigate how intrinsic and network activities influence intracellular dynamics. The fluidic isolation of each compartment further allows the selective application of drugs at identified sites to study activity-dependent synaptic transmission. This integrated microfluidic/microelectrode array (microMEA) platform is a valuable tool for studying various intracellular and synaptic dynamics in response to neuronal activity in a physiologically relevant context that resembles in vivo brain circuits.

AB - A series of new hybrid selenidostannates [Mn(en)2(hda)]2[Sn2Se6](1, en = ethylenediamine, hda = N-(2-hydroxyethyl)ethylenediamine), [Ni(teta)(en)][Ni(teta)(hda)][Sn4Se10] (2, teta = triethylenetetramine), [Mn(hda)2]n[SnMnSe4]n (3), [Mn(dien)2]n[SnMnSe4]n (4, dien = diethylenetriamine), and [Zn2(en)2(MU4-SnSe4)]n (5) were solvothermally synthesized in hda solvent and structurally characterized. 1 is composed of a discrete [Sn2Se6]4- anion and a complex [Mn(en)2(hda)]2+ cation as the counterion. 2 contains the [Ni(teta)(en)]2+ ion, [Ni(teta)(hda)]2+ ion and [Sn4S10]4- adamantane-like ion built from the corner-sharing connection of four [SnSe4]4- tetrahedra, which offers the rare example of hybrid selenidostannate combined with two different types of transition metal complexes as counterions. Both 3 and 4 contain a 1-D heterometallic [SnMnSe42-]n anionic chain constructed from [Sn/MnSe4] tetrahedra sharing opposite edges, whose Sn4+ and Mn2+ ions are situated at the same site in the lattice, but their chains exhibit two different configurations. 5 exhibits a new type of 2-D organic-decorated [Zn2(en)2(MU4-SnSe4)]n layer incorporating rare tetrahedral [ZnSe2(en)] complexes. Their optical and photocurrent response properties were studied, and density functional theory calculations for 5 were also performed. PMID- 30289149 TI - APOBEC3B protein expression and mRNA analyses in patients with high-grade serous ovarian carcinoma. AB - APOBEC3 enzymes are part of the innate immune system and they are important in retroviral defense. The number of mutations in ovarian cancer increases with rising levels of APOBEC3B mRNA. We could confirm that APOBEC3B mRNA is upregulated in ovarian cancer cell lines and in ovarian cancer tissue. We evaluated APOBEC3B expression in histologically defined subtypes of ovarian cancer to identify its influence on overall survival (OS) and progression-free survival (PFS). Tissue microarrays from 219 patients with high-grade serous (HGSC), 61 with low-grade serous (LGSC), 62 with endometrioid (EC) and 55 with clear cell (CCC) ovarian carcinoma were stained using an antibody against APOBEC3B. Real-time quantitative PCR was performed to detect APOBEC3B mRNA levels in 274 cases of HGSC, in 11 cases of LGSC, in 47 cases of EC and in 29 cases of CCC. Tumor-infiltrating lymphocytes (TILs) have been evaluated in a previous project. APOBEC3B staining was cytoplasmic as well as nuclear and both were positively correlated (P<0.001). In HGSC a trend was detectable for positive cytoplasmic staining as favorable regarding OS (P=0.283) and PFS (P=0.137). High levels of APOBEC3B mRNA were associated with prolonged PFS in HGSC in univariate analyses (P=0.043) and multivariate analyses (HR 0.55; 95%CI 0.35-0.88; P=0.012). APOBEC3B cytoplasmic staining and APOBEC3B mRNA were positively correlated with TILs. APOBEC3B in HGSC is related to an active immune infiltrate. However, there is no evidence for APOBEC3B as a clinically relevant prognostic biomarker.

AB - INTRODUCTION: Epilepsy is a chronic disease with high prevalence. Its impact in the quality of life is influenced by factors like disease characteristics, comorbidities, stigma perception and treatment adherence. AIM: To assess the quality of life, the social stigma and the treatment adherence of patients with epilepsy in our area. PATIENTS AND METHODS: Descriptive, observational and cross sectional study. Sociodemographic and clinical data were collected. We analyzed data on quality of life (QUOLIE-10), social stigma and treatment adherence through different questionnaires. RESULTS: 40 patients were studied. The mean age was 42.43 +/- 17.20 years, and the onset of epilepsy was 25.88 +/- 16.81 years. 55% were women. The score in the quality of life questionnaire was 19.28 +/- 8.03 points in men and 17.00 +/- 7.69 for women, this difference being not significant. There were also no significant differences for social stigma, with a mean of 11.50 +/- 13.47 points in men and 6.00 +/- 10.36 points for women (p = 0.152). According to the treatment adherence questionnaire (Morisky-Green), 70% of the patients studied were compliant with the treatment. CONCLUSIONS: Patients with epilepsy in our environment have a good quality of life, probably related to good treatment adherence and compliance. There is low perceived social stigma but people with epilepsy still trend to hide their condition. PMID- 30289151 TI - Neonatal hypotonia: is it a diagnostic challenge? AB - INTRODUCTION: Hypotonia is a frequent sign of disease in newborns. However, it's a nonspecific clinical finding: may be the presentation form of a systemic or neurological disease. AIMS: To study the main causes of neonatal hypotonia as well as to evaluate the diagnostic accuracy of the anamnesis and physical examination of the hypotonic newborn. PATIENTS AND METHODS: A 22-year retrospective study of hypotonic neonates admitted to the Neonatal Intensive Care Unit was conducted. It was performed an initial blind classification of hypotonia's type (central-CH, peripheral-PH or undetermined hypotonia) based on the clinical history and the recorded data of physical examination. RESULTS: 91 infants were included. 42 (46.2%) had prenatal history abnormalities: polyhydramnios (28.6%), intrauterine growth restriction (21.4%) and pelvic presentation (19.0%). 53 (58.2%) required resuscitation at birth. The main associated symptoms were respiratory distress (65.9%), feeding difficulties (36.5%) and decreased spontaneous movements (22.4%). The final diagnosis was reached in 64 newborns (70.3%): 81.3% with CH, 18.7% with PH. The positive predictive value of the initial classification was 97.9% in CH and 66.7% in PH group. The mortality rate was 8.8% and it was higher in PH group (58.3% vs 1.3%). CONCLUSIONS: Neonatal hypotonia can be associated to an extensive list of disorders. A detailed clinical history associated to a careful neurological evaluation present a high diagnostic predictive value that should guide the etiological investigation. PMID- 30289152 TI - Radiotherapy plus temozolomide or PCV in patients with anaplastic oligodendroglioma 1p19q codeleted. AB - INTRODUCTION: Radiotherapy with procarbazine, lomustine, and vincristine (PCV) improves overall survival in patients with anaplastic oligodendroglioma 1p19q codeleted. PATIENTS AND METHODS: This retrospective analysis investigated outcomes in patients with anaplastic oligodendroglioma 1p19q codeleted compared two different protocols (radiotherapy plus temozolomide or PCV). The primary end points were overall survival and progression-free survival. Secondary endpoint was the radiological response. RESULTS: A total of 48 patients were included. Mean age was 43 years (range: 19-66 years), 26 were male (54.1%). Twenty-one patients received PCV and 27 temozolomide. The baseline characteristics were not difference between the groups. The progression-free survival and overall survival in the PCV group were 7.2 and 10.6 years respectively and temozolomide were 6.1 and 9.2 years, both statistically significant. The radiological response was present in 80.9% in PCV arm and 70.2% in temozolomide arm there was not statistical differences. The multivariate Cox model showed only the significant parameters the use of PCV protocol. The toxicity grade 3 or 4 was present in 42.8% in PCV arm and 11.1% in temozolomide arm. CONCLUSIONS: The most common strategy in the Latin America community is the substitution of the PCV for temozolomide. This retrospective study showed superior efficacy of PCV than temozolomide. The Latin American community effort must be made to be able to have the drugs to available for using as a first line of treatment. PMID- 30289153 TI - [The importance of semiology and biochemistry in the diagnostic management of a peroxisomal biogenesis disorder]. AB - INTRODUCTION: Peroxisomal biogenesis disorders are due to mutations in the PEX genes, which code for peroxins that are required for peroxisomal biogenesis. Clinically, they are expressed as a Zellweger syndrome spectrum, and there is a wide phenotypic variety. They are diagnosed biochemically, and confirmation is molecular. The aim of this illustrative case is to highlight the importance of the clinical features and biochemical testing in the management of a peroxisomal disease. CASE REPORT: A 3-year-old boy with neonatal hypotonia, overall developmental delay and failure to thrive and a pattern of hypomyelinating leukodystrophy in brain resonance. The suspected diagnosis was a disorder affecting the biogenesis of the peroxisomes due to having found a variant with an uncertain meaning in PEX5. The clinical features, the biochemical studies and critical analysis, however, made this diagnosis unlikely. Emphasis is placed on the management that must be applied when a Zellweger syndrome spectrum is suspected. CONCLUSION: In the case reported here, a peroxisomal biogenesis disorder was suspected owing to an exome sequencing which, on being critically analysed together with the clinical features and the biochemical findings, made a peroxisomal disease very unlikely. In cases of clinical suspicion, backed up by neuroimaging, the main diagnostic management must be based on the biochemistry analysis. Although confirmation is molecular, these tests must be interpreted with caution. PMID- 30289154 TI - [Cognitive neurorehabilitation: the foundations and applications of neurologic music therapy]. AB - INTRODUCTION: Music is the result of a perception in the brain involving a number of cortical and subcortical areas in both brain hemispheres. Increased knowledge about brain plasticity and the numerous neuroimaging studies conducted in recent years have made it possible to further our understanding of the processing of musical stimuli in the brain. This has led to an interest in analysing and studying its application in the non-invasive treatment of certain dysfunctions or diseases with the aim of helping to achieve an improved quality of life. AIM: To outline the foundations and applications of the musical techniques that are used in cognitive neurorehabilitation. DEVELOPMENT: Following an initial summary of the processing of musical stimuli in the brain, the study goes on to explain the foundations of different techniques, as defined by neurologic music therapy, that are used efficaciously in cognitive neurorehabilitation. Sounds, which are the raw material of music, maintain a temporality and a sequencing that are a useful aid in the formation of temporal patterns of the cognitive functions, and constitute an assembly or framework that facilitates the learning of sequential information processing, such as memory. CONCLUSIONS: The techniques used in neurologic music therapy, which in recent years are being applied for cognitive neurorehabilitation, are not invasive and offer promising results that, together with further research, should be taken into account to be implemented alongside the conventional therapies of cognitive neurorehabilitation and stimulation.

PMID- 30289159 TI - Antagonistic recursivities and successive cover-ups: the case of private nuclear proliferation. AB - "Legal recursivity" is a concept introduced by socio-legal scholars to capture the progressive elaboration of transnational rules through policy linkages at the international and domestic levels, and the associated jurisdictional expansion of international institutions to new policy areas. Recursivity can take many forms, and this article introduces the concept of "antagonistic recursivity" to capture a dual process of recursive legal innovation and antagonistic obstruction by the same policy actors. The article shows how such antagonistic recursivity worked in the case of the global fight against private nuclear proliferators after the 2003 revelations about the reach of the A. Q. Khan network. In the case under study, antagonistic recursivities took the form of executive-driven innovation in rule making and simultaneous subversion of the same rules by the executive most implicated in the new cycle of policy innovation: the United States government. This paradox can be explained in the following manner. Antagonistic recursivity, the article demonstrates, is likely to emerge when legal rules of global governance have already been previously defined in an opaque manner, so as to help hegemons follow multiple foreign policy goals: the subversion of the most recent policy innovations is then the unfortunate result of attempts to hide prior cover-ups rather than a purposeful violation of new rules.

PMID- 30289161 TI - Long-term neurotoxicity and raynaud's phenomenon in patients treated with cisplatin-based chemotherapy for malignant ovarian germ cell tumor. AB - INTRODUCTION: The aim was to evaluate "overall neuropathy", defined as peripheral paresthesias and Raynaud's phenomenon, in long-term survivors of malignant ovarian germ cell tumors (MOGCTs) treated with cisplatin-based chemotherapy (CBCT) MATERIAL AND METHODS: Ninety-three MOGCT survivors recorded in Norway in 1980-2009 (median follow-up: 15 years) were included in this analysis. Forty-nine received CBCT (CBCT group) and 44 received other or no chemotherapy (non-CBCT group). Applying the scale for chemotherapy-induced neurotoxicity, the prevalence of overall neuropathy (i.e., score >1 on a 0 to 3 scale) was compared between the two groups. 40 women from the CBCT group also underwent neurophysiological and neurological examinations; results from the neurological examination were graded according to the National Cancer Institute-Common Terminology Criteria for Adverse Effects version 4 (NCI-CTCAE scale v4). These women were then categorized into subgroups of low (<=3 cycles of CBCT, n=23) and high CBCT (>=4 cycles of CBCT, n=17) RESULTS: Twenty-eight (57%) women from the CBCT group reported overall neuropathy, compared to 20 (45%) in the non-CBCT group (p=0.06). Of the 40 MOGCT survivors in the CBCT group who underwent neurophysiological and neurological examinations, 14 (35%) showed NCI-CTCAE grade >=1 signs or symptoms of peripheral neuropathy. Pathological findings of NCI-CTCAE grade 2 or 3 signs or symptoms were found in four survivors (10%) from the high CBCT subgroup, all of whom also showed objective signs of neuropathy CONCLUSIONS: Though about half of our MOGCT survivors reported overall neuropathy after CBCT, more severe pathological neurological/neurophysiological findings that impacted daily living were recorded in only 10% of them. Our observations of a similar prevalence of self-reported overall neuropathy in the CBCT and non-CBCT group, combined with limited objective neurological findings, warrant further study to increase the understanding of the specific patho-physiological pathways of long-term, CBCT induced neuropathy.

AB - We introduce a novel class of factor analysis methodologies for the joint analysis of multiple studies. The goal is to separately identify and estimate 1) common factors shared across multiple studies, and 2) study-specific factors. We develop an Expectation Conditional-Maximization algorithm for parameter estimates and we provide a procedure for choosing the numbers of common and specific factors. We present simulations for evaluating the performance of the method and we illustrate it by applying it to gene expression data in ovarian cancer. In both, we clarify the benefits of a joint analysis compared to the standard factor analysis. We have provided a tool to accelerate the pace at which we can combine unsupervised analysis across multiple studies, and understand the cross-study reproducibility of signal in multivariate data. An R package (MSFA), is implemented and is available on GitHub. This article is protected by copyright. All rights reserved. PMID- 30289164 TI - Plausible folk theories: throwing veils of plausibility over zones of ignorance in global governance. AB - In an age of expertise, where knowledge ostensibly reigns, global governance not infrequently settles for ignorance. To understand this puzzle, this article draws upon extensive empirical research on two sites within the global governance of finance. One is directed to the suppression of money laundering and combating the financing of terrorism by the Financial Action Task Force and International Monetary Fund. Another intends to stimulate the supply of otherwise scarce money to financial markets through global lawmaking by the UN Commission on International Trade Law. In both cases vast enterprises of global regulation and lawmaking proceed on weakly founded justificatory rhetorics designated here as 'plausible folk theories.' Six properties make a folk theory plausible: parsimony, face validity, rhetorical compactness, ambiguity, affinity with extant beliefs, and unexamined premises and logics. Plausible folk theories offer organizational benefits to IOs. They also allow a politics of temporality that may shorten temporal horizons, or weaken and eliminate IO accountability. Finally, three variants of ignorance contribute to choices by international organizations not to get beyond plausible folk theories to justify their regulatory and lawmaking initiatives: inadvertent ignorance, willful ignorance, and strategic or rational ignorance. PMID- 30289165 TI - Decreasing influence of arbitrarily applicable verbal relations of recreational gamblers: A randomized controlled trial. AB - Twenty-one recreational gamblers were randomly assigned to two groups; one group was exposed to a conditional discrimination relational training task to bias choice allocation to a black machine presented concurrently with a red machine, and the other group underwent the same relational training task immediately followed by a defusion procedure, designed to expand upon the relations developed in the initial relational task. Both groups completed a simulated slot-machine task before and after the relational training task, with or without the defusion procedure. Results showed that 9 of 11 participants in the relational training only group showed an increased bias toward the black machine, compared to only 4 of 10 in the relational training plus defusion group; this latter group also showed greater matched responding. Results suggest that expanding verbal relational networks may reduce the influence of any single verbal relation on gambling choice behavior. PMID- 30289166 TI - Individual differences in learning and biogenic amine levels influence the behavioural division between foraging honeybee scouts and recruits. AB - Animals must effectively balance the time they spend exploring the environment for new resources and exploiting them. One way that social animals accomplish this balance is by allocating these two tasks to different individuals. In honeybees, foraging is divided between scouts, which tend to explore the landscape for novel resources, and recruits, which tend to exploit these resources. Exploring the variation in cognitive and physiological mechanisms of foraging behaviour will provide a deeper understanding of how the division of labour is regulated in social insect societies. Here, we uncover how honeybee foraging behaviour may be shaped by predispositions in performance of latent inhibition (LI), which is a form of non-associative learning by which individuals learn to ignore familiar information. We compared LI between scouts and recruits, hypothesizing that differences in learning would correlate with differences in foraging behaviour. Scouts seek out and encounter many new odours while locating novel resources, while recruits continuously forage from the same resource, even as its quality degrades. We found that scouts show stronger LI than recruits, possibly reflecting their need to discriminate forage quality. We also found that scouts have significantly elevated tyramine compared to recruits. Furthermore, after associative odour training, recruits have significantly diminished octopamine in their brains compared to scouts. These results suggest that individual variation in learning behaviour shapes the phenotypic behavioural differences between different types of honeybee foragers. These differences in turn have important consequences for how honeybee colonies interact with their environment. Uncovering the proximate mechanisms that influence individual variation in foraging behaviour is crucial for understanding the ecological context in which societies evolve. PMID- 30289167 TI - The Outcome-Representation Learning Model: A Novel Reinforcement Learning Model of the Iowa Gambling Task. AB - The Iowa Gambling Task (IGT) is widely used to study decision-making within healthy and psychiatric populations. However, the complexity of the IGT makes it difficult to attribute variation in performance to specific cognitive processes. Several cognitive models have been proposed for the IGT in an effort to address this problem, but currently no single model shows optimal performance for both short- and long-term prediction accuracy and parameter recovery. Here, we propose the Outcome-Representation Learning (ORL) model, a novel model that provides the best compromise between competing models. We test the performance of the ORL model on 393 subjects' data collected across multiple research sites, and we show that the ORL reveals distinct patterns of decision-making in substance-using populations. Our work highlights the importance of using multiple model comparison metrics to make valid inference with cognitive models and sheds light on learning mechanisms that play a role in underweighting of rare events. PMID- 30289168 TI - Differentiation of self and trait anxiety: A cross-cultural perspective. AB - Cultural differences are likely to affect the ability to deal with anxiety. We investigated this issue among four cultural groups-Germans and Italians (Europeans living in South Tyrol, Italy), Jews and Arabs (Israelis)-in terms of their levels of differentiation of self, trait anxiety and somatic symptoms. We also examined the relationship of differentiation of self to trait anxiety and somatic symptoms. The sample consisted of 824 students: 387 Israelis (mean age 23.6) and 437 Europeans (mean age 22.3). Israeli participants reported lower levels of trait anxiety than European students. Jewish students reported lower trait anxiety than Arab students (mean difference = -.14, p < .009), while there was no difference between German and Italian students (mean difference = .03, p > .99). Jews reported a significantly lower level of emotional cutoff than Arabs (mean difference = -.45, p < .001), and Germans reported a significantly lower level of emotional reactivity than Italians (mean difference = .29, p < .001). Emotional reactivity and I-position predicted all participants' trait anxiety. On the whole, results point to the importance of examining differentiation of self when trying to reduce trait anxiety, as well as some important cultural differences. PMID- 30289169 TI - Internalising symptoms and verbal working memory in school-age children: A processing efficiency analysis. AB - The current study investigated differential contributions of internalising symptoms (state anxiety, trait anxiety, depression) to school-age children's verbal short-term (STM) and working memory (WM) span accuracy and efficiency (microanalysis of response times). Children's (N = 125, Mage = 11.44 years) STM/WM was assessed with simple/complex span tasks. Our analyses revealed that: (a) children with high levels of state anxiety displayed reduced simple span accuracy (on Word span) and poorer efficiency on both simple (preparatory intervals, interword pauses) and complex span (preparatory intervals) response time segments; (b) trait anxiety was a negative predictor of children's complex span accuracy, as well as their efficiency on both simple (word durations) and complex span (interword pauses) response time measures; (3) depressive symptoms predicted longer simple span interword pauses. Findings indicate that while all internalising symptoms were predictive of children's poorer memory search efficiency, especially during the "silent", executive intervals (interword pauses), anxiety symptoms were specifically predictive of children's impaired span accuracy and other efficiency indicators (preparatory intervals, word durations). The study highlights the differential contributions of state, trait anxiety, and depressive symptoms to STM/WM in children, emphasising the need to measure both accuracy and efficiency to assess the role that such symptoms play in children's performance. PMID- 30289170 TI - Disentangling the contributions of maternal and fetal factors to estimate stillbirth risks for intrapartum adverse events in Tanzania and Uganda. AB - OBJECTIVE: To estimate the stillbirth risk associated with intrapartum adverse events, controlling for fetal and maternal factors. METHODS: The present study was an analysis of cross-sectional patient-record and facility-file data from women with viable fetuses who experienced obstetric adverse events at 23 hospitals and 38 health centers in Tanzania (between December 2015 and October 2016), and 22 hospitals, 16 level-4 health centers, and five level-3 health centers in Uganda (between May 2016 and September 2017). Adverse events were categorized in three severity groups (postpartum, intrapartum non-near-miss, and intrapartum near-miss) to calculate stillbirth rates and adjusted prevalence ratios. RESULTS: Data from 3816 women in Tanzania and 8305 in Uganda were included. Compared with postpartum adverse events, intrapartum near-miss was associated with a 3.73- and 4.55-fold higher prevalence of stillbirth in Uganda and Tanzania, respectively. Most women who experienced near-miss had organ dysfunction on arrival or developed it soon after. The risk of stillbirth was higher among preterm deliveries compared with term deliveries, and was 42% and 59% lower in Tanzania and Uganda, respectively, for cesarean deliveries compared with vaginal deliveries after intrapartum non-near-miss adverse events. CONCLUSION: Stillbirth risk increased with severity of complications and was higher among premature deliveries. Survival was higher for cesarean deliveries in intrapartum non-near-miss complications, identifying the opportunity to prevent deterioration by timely actions. PMID- 30289171 TI - Managing tensions in assessment: moving beyond either-or thinking. AB - CONTEXT: In health professions education, assessment systems are bound to be rife with tensions as they must fulfil formative and summative assessment purposes, be efficient and effective, and meet the needs of learners and education institutes, as well as those of patients and health care organisations. The way we respond to these tensions determines the fate of assessment practices and reform. In this study, we argue that traditional 'fix-the-problem' approaches (i.e. either-or solutions) are generally inadequate and that we need alternative strategies to help us further understand, accept and actually engage with the multiple recurring tensions in assessment programmes. METHODS: Drawing from research in organisation science and health care, we outline how the Polarity ThinkingTM model and its 'both-and' approach offer ways to systematically leverage assessment tensions as opportunities to drive improvement, rather than as intractable problems. In reviewing the assessment literature, we highlight and discuss exemplars of specific assessment polarities and tensions in educational settings. Using key concepts and principles of the Polarity ThinkingTM model, and two examples of common tensions in assessment design, we describe how the model can be applied in a stepwise approach to the management of key polarities in assessment. DISCUSSION: Assessment polarities and tensions are likely to surface with the continued rise of complexity and change in education and health care organisations. With increasing pressures of accountability in times of stretched resources, assessment tensions and dilemmas will become more pronounced. We propose to add to our repertoire of strategies for managing key dilemmas in education and assessment design through the adoption of the polarity framework. Its 'both-and' approach may advance our efforts to transform assessment systems to meet complex 21st century education, health and health care needs. PMID- 30289172 TI - Prolonged exposure to carbon nanoparticles induced methylome remodeling and gene expression in zebrafish heart. AB - Growing black carbon (BC) emission has become one of the major urgent environmental issues facing human beings. Usually, BC or BC-containing carbon nanoparticles (CNPs) were recognized as non-directly toxic components of atmospheric particulate matter. However, epidemiology studies have provided much evidence of the associations of exposure of particulate-containing carbon particles with cardiovascular diseases. There are still no related studies to support the epidemiological conclusions. Hence, in this article we exposed adult zebrafish to CNPs for 60 days, and then explored the heart location and potential adverse effects on cardiac tissues of these nanosized carbon particles. Our results first showed direct visualization of cardiac endothelial uptake and heart deposition of CNPs in zebrafish. In addition, CNPs caused significant ultrastructural alterations in myocardial tissue and induced the expression of inflammatory cytokines in a dose-dependent manner, resulting in sub-endocardial inflammation and cell apoptosis. Moreover, our data demonstrated the perturbations caused by CNPs on DNA methylation, suggesting that DNA methylome remodeling might play a critical role in CNP-induced cardiotoxicity in zebrafish heart. Therefore, this study not only proved a laboratory link between CNP exposure and cardiotoxicity in vivo, but also indicated a possible toxicity mechanism involved. PMID- 30289173 TI - Beta-lactam-induced severe neutropaenia: a descriptive study. AB - The objectives of this study were to describe the characteristics and natural history of beta-lactam-induced severe neutropaenia and to evaluate the risk of recurrences after another beta-lactam readministration. Reports of pure agranulocytosis associated with a beta-lactam exposure within the 10 days preceding the neutropaenia were extracted from the French Pharmacovigilance Database over the year 2010. Cases with another evident cause or more likely attributable to another drug were excluded. Data were analyzed for demographics, clinical and biological features, prognosis factors, granulocyte colony stimulating factors administration and outcome. Sixty-two cases were included (median age: 65 years). The median duration of treatment before neutropaenia was 16 days. In 47% of cases, the diagnosis was made on a systematic blood cell count. The median neutrophil count at nadir was 0.125 * 109 /L, and bone marrow examination evidenced features of neutrophilic maturation arrest or aplasia in 21 patients, hyperplasia of granulopoietic cells in three and normal findings in five. Three patients developed severe sepsis. All but one recovered a normal blood cell count within 2-56 days after beta-lactam discontinuation. The last patient died from recurrent severe septic shock. No significant effect of granulocyte colony stimulating factor on the mean duration of haematological recovery was found. Among the 21 patients who later received another beta-lactam, two experienced recurrence of the neutropaenia after receiving a beta-lactam from another subfamily. Beta-lactam-induced agranulocytosis was usually observed after prolonged treatment, and severe complications are uncommon. In most patients, a subsequent treatment with another beta-lactam was well tolerated. PMID- 30289174 TI - Knowledge regarding and patterns of genetic testing in patients newly diagnosed with breast cancer participating in the iCanDecide trial. AB - BACKGROUND: The current study reports rates of knowledge regarding the probability of a BRCA1 and/or S pathogenic variant and genetic testing in patients with breast cancer, collected as part of a randomized controlled trial of a tailored, comprehensive, and interactive decision tool (iCanDecide). METHODS: A total of 537 patients newly diagnosed with early-stage breast cancer were enrolled at the time of their first visit in 22 surgical practices, and were surveyed 5 weeks (496 patients; Response Rate [RR], 92%) after enrollment after treatment decision making. Primary outcomes included knowledge regarding the probability of carrying a BRCA1 and/or BRCA2 pathogenic variant and genetic testing after diagnosis. RESULTS: Overall knowledge regarding the probability of having a BRCA1 and/or BRCA2 pathogenic variant was low (29.8%). Significantly more patients in the intervention group compared with the control group had knowledge regarding the probability of a BRCA1 and/or BRCA2 pathogenic variant (35.8% vs 24.4%; P <.006). In multivariable logistic regression, the intervention arm remained significantly associated with knowledge regarding the probability of having a BRCA1 and/or BRCA2 pathogenic variant (odds ratio, 1.79; 95% confidence interval, 1.18-2.70). CONCLUSIONS: The results of the current study suggest that although knowledge concerning the probability of having a BRCA1 and/or BRCA2 pathogenic variant remains low in this patient population, the interactive decision tool improved rates compared with a static Web site. As interest in genetic testing continues to rise, so will the need to integrate tools into the treatment decision process to improve informed decision making. PMID- 30289175 TI - The toll like receptor 4-myeloid differentiation factor 88 pathway is essential for particulate matter-induced activation of CD4-positive cells. AB - Asian sand dust (ASD), a type of particulate matter (PM) found in Asia, can be transported to East Asia. We recently found that acute splenic inflammation is induced by ASD in mouse models. In this study, we examined the effect of sub chronic ASD exposure on mouse immune cells. Mice were intratracheally administered ASD once every 2 weeks for 8 weeks and killed 24 hours after the final administration. Wild-type (WT) mice showed increased cell viability after ASD administration. In contrast, ASD administration induced splenocyte activation in toll-like receptor (TLR)2-/- , but not TLR4-/- mice. Furthermore, concanavalin A-induced interleukin-2 production increased after ASD administration in WT and TLR2-/- mice, but not in TLR4-/- or myeloid differentiation factor (MyD)88-/- mice. Immunoblotting demonstrated that nuclear factor kappaB (NF-kappaB) was activated in WT mice, but not in TLR4-/- or MyD88-/- mice. The NF-kappaB dependent gene products CDK2 and intercellular cell adhesion molecule-1 were upregulated upon ASD administration in WT mice, but not in TLR4-/- or MyD88-/- mice. Furthermore, the particles themselves, rather than particle constituents, activated NF-kappaB in CD4-positive cells through the TLR4 or MyD88 pathway. Taken together, these results indicate that particle-induced splenic inflammation occurs via TLR4-MyD88 signaling. PMID- 30289176 TI - Improved, one-pot synthesis of 6-[18 F]fluorodopamine and quality control testing for use in patients with neuroblastoma. AB - 6-[18 F]Fluorodopamine ([18 F]F-DA) is taken into cells via the norepinephrine transporter (NET). Recent [18 F]F-DA positron emission tomography-computed tomography (PET-CT) imaging of adult neuroendocrine tumors shows a dramatic improvement in sensitivity over the standard-of-care, meta-iodobenzylguanidine (MIBG) single-photon emission computed tomography (SPECT)-CT. A new precursor (ALPdopamineTM) allows no-carrier-added synthesis resulting in high-molar activity [18 F]F-DA. Automated synthesis of [18 F]F-DA was performed in a single reactor using a two-step procedure: 1) fluorination via thermolysis of a diaryliodonium salt precursor, followed by 2) acid hydrolysis. Phase transfer agents, Kryptofix 222 and two tetraalkylammonium salts, were investigated. Optimized synthesis of [18 F]F-DA was achieved in 56 to 60 minutes (26% end of synthesis [EOS], nondecay corrected). The product passed all Food and Drug Administration (FDA)-required quality control testing for human use. Accumulation of [18 F]F-DA in SK-N-BE(2)-C (high NET expression) cells was significantly higher than in SH-EP (minimal NET expression) cells (P < 0.0001). ALPdopamine provides an effective scaffold for the routine production of [18 F]F-DA for human use. Validation of uptake by neuroblastoma (NB) cell lines supports the use of [18 F]F-DA for imaging NB patients. A pediatric NB imaging trial using [18 F]F-DA PET has been approved (Investigational New Drug application (IND) no. 138638) based on the methods reported here. We expect [18 F]F-DA will be localized in NB tumors and that high-quality functional images will be obtained within minutes after injection. PMID- 30289177 TI - An ex vivo bladder model with detrusor smooth muscle removed to analyse biologically active mediators released from the suburothelium. AB - KEY POINTS: Studies of urothelial cells, bladder sheets or lumens of filled bladders have suggested that mediators released from urothelium into suburothelium (SubU)/lamina propria (LP) activate mechanisms controlling detrusor excitability. None of these approaches, however, has enabled direct assessment of availability of mediators at SubU/LP during filling. We developed an ex vivo mouse bladder preparation with intact urothelium and SubU/LP but no detrusor, which allows direct access to the SubU/LP surface of urothelium during filling. Pressure-volume measurements during filling demonstrated that bladder compliance is governed primarily by the urothelium. Measurements of purine mediators in this preparation demonstrated asymmetrical availability of purines in lumen and SubU/LP, suggesting that interpretations based solely on intraluminal measurements of mediators may be inaccurate. The preparations are suitable for assessments of release, degradation and transport of mediators in SubU/LP during bladder filling, and are superior to experimental approaches previously used for urothelium research. ABSTRACT: The purpose of this study was to develop a decentralized (ex vivo) detrusor smooth muscle (DSM)-denuded mouse bladder preparation, a novel model that enables studies on availability of urothelium derived mediators at the luminal and anti-luminal aspects of the urothelium during filling. Urinary bladders were excised from C57BL6/J mice and the DSM was removed by fine-scissor dissection without touching the mucosa. Morphology and cell composition of the preparation wall, pressure-volume relationships during filling, and fluorescent dye permeability of control, protamine sulfate- and lipopolysaccharide-treated denuded bladders were characterized. The preparation wall contained intact urothelium and suburothelium (SubU)/lamina propria (LP) and lacked the DSM and the serosa. The utility of the model for physiological research was validated by measuring release, metabolism and transport of purine mediators at SubU/LP and in bladder lumen during filling. We determined asymmetrical availability of purines (e.g. ATP, ADP, AMP and adenosine) in lumen and at SubU/LP during filling, suggesting differential mechanisms of release, degradation and bilateral transurothelial transport of purines during filling. Some observations were validated in DSM-denuded bladder of the cynomolgus monkey (Macaca fascicularis). The novel model was superior to current models utilized to study properties of the urothelium (e.g. cultured urothelial cells, bladder mucosa sheets mounted in Ussing chambers or isolated bladder strips in organ baths) in that it enabled direct access to the vicinity of SubU/LP during authentic bladder filling. The model is particularly suitable for understanding local mechanisms of urothelium-DSM connectivity and for broad understanding of the role of urothelium in regulating continence and voiding.

AB - The principal outcome was to identify which hypnotics substances, medicated (benzodiazepines, antihistamine, antidepressant...) or not medicated (herbal medicine, homeopathy, melatonin...), were consumed by community pharmacy patients who reported taking something for sleep disorder, and which factors can influence the consumption of medicated substance rather than nonmedicated substance. Data were collected via a network of 73 partner pharmacies around Nantes, France. Patients who reported taking a substance to sleep completed a questionnaire that collected data relative to the different substances consumed by that person for sleep, and the desired effect. Substances were classified in Hypnotic Drug Substances and nonmedicated hypnotic substances. A logistical regression was done in order to highlight the factors associated with the consumption of Hypnotic Drug Substance rather than nonmedicated hypnotic substances. Six hundred and forty-seven patients were included, with an average age of 58 years and 74% female. The principal strategy employed to combat sleep disorder was the consumption of Hypnotic Drug Substance (54%), followed by herbal medicine (32%) and homeopathy (19%). The factors positively associated with the consumption of a Hypnotic Drug Substance are age, living alone, being out of work, or in the process of looking for a job and being a parent. In our survey, the use of Hypnotic Drug Substance to help patients with sleep is far from systematic. On the other hand, among patients who consume HDS, misuse is still significant, particularly in terms of the duration of consumption. PMID- 30289179 TI - Peripheral T-cell non-Hodgkin lymphoma manifesting as a primary lesion on the lip: A rare case report. AB - Primary manifestations of extraganglion non-Hodgkin lymphoma (NHL) from T-cells in the oral cavity are rare and often difficult to diagnose. Herein, we describe a case of T-cell NHL with a primary lesion on the lip diagnosed with a 25-year old woman. The patient reported the appearance of the initial lesion on the upper lip, which advanced to the hard palate and oral mucosa. Histological examination and immunohistochemistry were compatible with peripheral T-cell NHL without further specifications. The proposed treatment consisted of six cycles of multiagent chemotherapy. The patient died from complications of the disease before the third cycle of chemotherapy. Understanding the clinical signs of lymphoma is important for the early diagnosis of this disease to avoid aggressive and potentially fatal behavior.

PMID- 30289180 TI - Psychotic experiences are associated with health anxiety and functional somatic symptoms in preadolescence. AB - BACKGROUND: Health anxiety (HA) is an increasing public health problem related to increased health service costs, and associated with functional somatic symptoms (FSS) and considerable personal suffering. Abnormal bodily experiences which may resemble HA and FSS are common in psychotic disorders, but a potential link between HA and psychosis vulnerability in childhood is largely unexplored. The current study estimates the association between subclinical psychotic experiences (PE) and HA and FSS in a general population cohort of preadolescents. METHODS: The study population consisted of 1,572 11-12-year-old children from the Copenhagen Child Cohort 2000. PE were comprehensibly assessed as either present or not present using the Kiddie Schedule of Affective Disorders and Schizophrenia psychosis section. HA and FSS were assessed by self-report on validated questionnaires. Additional variables on general psychopathology, puberty, and chronic somatic illness were also obtained. RESULTS: Psychotic experiences were associated with the top 10% high scores of HA (Odds Ratio (OR) 3.2; 95% CI: 2.1 4.8) and FSS (OR 4.6; 95% CI: 3.1-6.9) in univariate analyses. After mutual adjustment, the association was reduced to (HA: OR 2.3; 95% CI: 1.5-3.5; FSS: OR 3.7; 95% CI: 2.4-4.7), suggesting interdependence. Further adjustment for potential confounders and general psychopathology only reduced the associations slightly: HA OR 2.2 (95% CI: 1.4-3.4); FSS OR 3.3 (95% CI: 2.1-5.2). Secondary analyses of subdimensions of HA showed that PE were associated with fears (OR 3.0; 95% CI: 2.0-4.6) and daily impact of HA symptoms (OR 5.0; 95% CI: 3.4-7.5), but not help seeking (OR 1.2; 95% CI: 0.7-2.1). CONCLUSIONS: This is the first study to investigate the associations between PE and HA and FSS, respectively. PE were significantly associated with HA and FSS over and above general psychopathology in preadolescence. Individuals with PE expressed high levels of health-related fears and daily impact, but no corresponding help-seeking behavior. PMID- 30289183 TI - The Importance of Statistical Power Calculations. PMID- 30289184 TI - Molecular receptors for recognition and sensing of nucleotides. AB - Nucleotides have a variety of functions in cellular metabolism and they are the constitutes of nucleic acids. Synthetic receptors and sensors are required to reveal the role of nucleotides in living organisms and mechanisms of signal transduction events. In recent years, a large number of nucleotide-selective synthetic receptors have been devised that utilize different molecular designs and sensing mechanisms. This Minireview presents a recent progress in the design of synthetic molecular receptors for selective recognition of nucleotides in aqueous solution. The binding properties of receptors and the origins of their selectivity for a particular nucleotide are discussed. PMID- 30289185 TI - Primary hyperparathyroidism: should surgery be performed on all patients? Current evidence and residual uncertainties. AB - Primary hyperparathyroidism (pHPT) is the third most common endocrine disease and is characterized by hypercalcaemia and elevated or inappropriately 'normal' levels of the parathyroid hormone (PTH). The main target organs of PTH are the skeletal system and the kidneys. Before the 1970s, pHPT was a rarely detected disease associated with notable morbidity and premature mortality. Introduction of biochemical screening, allowing for a wide range of indications, has contributed to the detection of the full spectrum of the disease. A new entity with an isolated elevation of PTH, normocalcaemic HP, has emerged and is currently being explored. The highest incidence of pHPT, 3-5%, is observed amongst women, and the prevalence increases with age. The female-to-male ratio is 3-4 : 1 except in younger patients where distribution is equal and known hereditary causes account for approximately 10% of the cases. In the last few decades, it has become evident that fewer patients than previously believed are truly asymptomatic. The cause of pHPT is often a benign tumour, a parathyroid adenoma, and the only definite treatment is parathyroidectomy (PTX). No medical treatment, single or combined, can achieve a curing of pHPT. Recent data indicate that PTX, despite being proven to be cost-effective compared to conservative treatment, is underutilized, especially in elderly pHPT patients. The decision of PTX should always be based on a safe diagnosis, and the potential benefits of curative treatment should not be outweighed by the risks of surgery or anaesthesia. PMID- 30289186 TI - Superselective endovascular tissue access using trans-vessel wall technique: feasibility study for treatment applications in heart, pancreas and kidney in swine. AB - OBJECTIVES: With the emergence of targeted cell transplantation and gene therapy, there is a need for minimally invasive tissue access to facilitate delivery of therapeutic substrate. The objective of this study was to demonstrate the suitability of an endovascular device which is able to directly access tissue and deliver therapeutic agent to the heart, kidney and pancreas without need to seal the penetration site. METHODS: In vivo experiments were performed in 30 swine, including subgroups with follow-up to evaluate complications. The previously described trans-vessel wall (VW) device was modified to be sharper and not require tip detachment to seal the VW. Injections into targets in the heart (n = 13, 24-h follow-up n = 5, 72-h follow-up n = 3), kidney (n = 8, 14-day follow-up n = 3) and pancreas (n = 5) were performed. Some animals were used for multiple organ injections. Follow-up consisted of clinical monitoring, angiography and necropsy. Transvenous (in heart) and transarterial approaches (in heart, kidney and pancreas) were used. Injections were targeted towards the subepicardium, endomyocardium, pancreas head and tail, and kidney subcapsular space and cortex. RESULTS: Injections were successful in target organs, visualized by intraparenchymal contrast on fluoroscopy and by necropsy. No serious complications (defined as heart failure or persistent arrhythmia, haemorrhage requiring treatment or acute kidney injury) were encountered over a total of 157 injections. CONCLUSIONS: The trans-VW device can achieve superselective injections to the heart, pancreas and kidney for delivery of therapeutic substances without tip detachment. All parts of these organs including the subepicardium, pancreas tail and renal subcapsular space can be efficiently reached. PMID- 30289187 TI - Urine drug screening for early detection of unwitting use of fentanyl and its analogues among people who inject heroin in Sydney, Australia. AB - INTRODUCTION AND AIMS: North America has witnessed a dramatic rise in fatal opioid overdoses due to the unwitting consumption of non-pharmaceutical fentanyl and its analogues. While some of the drivers of this crisis-including profitability and access to high-potency opioids through internet sources-also apply in Australia, to our knowledge, there have been no ongoing surveillance studies of local populations. Therefore, this pilot study aimed to detect unintentional fentanyl consumption among people who inject heroin through instant urine screening, and determine the feasibility and acceptability of voluntary urinalysis of clients at the Medically Supervised Injecting Centre, Kings Cross, Sydney. DESIGN AND METHODS: Brief surveys and urine drug screens were conducted with 67 participants in Wave 1 (October 2017) and 51 participants in Wave 2 (March 2018). Urine samples were tested with BTNX Rapid ResponseTM fentanyl urine strip test at a detection level of 20 ng/mL norfentanyl. These strips also cross react to numerous fentanyl analogues. RESULTS: There were no cases where positive urine tests suggested unwitting fentanyl use detected in this study. DISCUSSION AND CONCLUSIONS: These negative findings contrast sharply with similar Canadian studies. While no cases of fentanyl-laced heroin use have been detected so far, we have demonstrated that this surveillance design is low-cost, feasible and scalable approach to monitoring the considerable public-health threat of undetected fentanyl and its analogues in Australia. Further validation of cross reactivity of test strips would strengthen this method. PMID- 30289188 TI - Effect of hemodialysis on respiratory mechanics in acute kidney injury patients. AB - INTRODUCTION: Hemodialysis (HD) is one treatment for acute kidney injury (AKI) patients. Studies have shown that this dialysis modality may lead to changes in pulmonary function with an impact on prognosis. The aim of our study was to evaluate changes in respiratory mechanics and oxygenation of AKI patients admitted to an intensive care unit who were undergoing intermittent mechanical ventilation (IMV) and daily HD. METHODS: This prospective cohort study evaluated 94 AKI patients and 234 HD sessions. Pulmonary static compliance (Pcs), resistance (Rsr), and arterial partial pressure of oxygen and the fraction of inspired oxygen (PaO2 /FiO2 ) ratio were assessed during the initial three-day period of daily HD therapy. FINDINGS: Psc increased progressively during HD sessions, from 39.4 +/- 21.4 mL/cm H2 O prior to the initial dialysis to 55.5 +/- 25.2 at the end of the last dialysis during the study period (P = 0.04). Similarly, Rsr and PaO2 /FiO2 ratio also improved, from 11.1 +/- 6.3 cm H2 O/L/s prior to the initial dialysis to 8.8 +/- 4.2 at the end of the last dialysis (P =0.0027) and from 228 +/- 85 prior to the initial dialysis to 312.1 +/- 111.5, P < 0.001, to the end of the last dialysis, respectively. CONCLUSION: This study showed that AKI patients undergoing IMV and daily HD improve their respiratory mechanics and oxygenation. PMID- 30289189 TI - Moving between ideologies in self-management support-A qualitative study. AB - BACKGROUND: Reforms in current health policy explicitly endorse health promotion through group-based self-management support for people with long-term conditions. Health promotion and traditional medicine are based on different logics. Accordingly, health professionals in health-promoting settings demand the adoption of new practices and ways of thinking. OBJECTIVES: The objective of our study was to investigate how health professionals perceive the health-promoting group-based self-management support that is politically initiated for people with long-term conditions. DESIGN: This study had a qualitative research design that included focus group interviews and was guided by a social constructivist paradigm in which group-based self-management was viewed as a social construction. Different logics at play were analysed through the theoretical lens of institutional logic. Discussions among participants show frames of references seen as logics. SETTING AND PARTICIPANTS: We recruited health professionals from group-based health-promoting measures for people with type 2 diabetes in Norway. Two focus groups comprising four and six participants each were invited to discuss the practices and value of health promotion through group-based self management support. RESULTS: The analysis resulted in three themes of discussion among participants that contained reflections of logics in movement. Health professionals' discussions moved between different logics based on the importance of expert-based knowledge on compliance and on individual lifestyle choices. DISCUSSION AND CONCLUSION: The study indicates that health promotion through self management support is still a field "in the making" and that professionals strive to establish new logics and practices that are not considered difficult to manage or do not contain incompatible understandings. PMID- 30289190 TI - Association between pain-related fear and presenteeism among eldercare workers with low back pain. AB - BACKGROUND: Presenteeism (work productivity loss at work) and low back pain (LBP) are prevalent among eldercare workers. Presenteeism is a serious emerging problem in an occupational setting. While many studies report the impact of pain-related fear on absenteeism, its impact on presenteeism remains unclear. METHODS: We conducted a cross-sectional study to investigate the association between pain related fear and presenteeism among 505 eldercare workers with LBP. We measured pain-related fear using the 11-item Tampa Scale for Kinesiophobia (TSK-11). We used the Work Limitations Questionnaire (WLQ) to estimate productivity loss due to presenteeism with items including Time Management, Mental-Interpersonal Demands, Physical Demands, and Output Demands. The presenteeism was categorized into no (<5%), mild (5%-10.9%), moderate (11%-16.9%), and severe presenteeism (>=17%). We further performed ordinal logistic regression analyses, and the covariates were age, sex, pain intensity, pain disability, and psychosocial factors. Multiple imputation was conducted to provide informed estimates for observations with missing data. RESULTS: After adjustment, a higher TSK score was significantly associated with a higher presenteeism (proportional OR = 1.10, 95% CI = 1.06-1.15). A significant association of TSK with all WLQ subscales was retained even after the adjustment (Time Management: proportional OR = 1.04, 95% CI = 1.01-1.08; Mental-Interpersonal Demands: proportional OR = 1.08, 95% CI = 1.04-1.12; Physical Demands: proportional OR = 1.04, 95% CI = 1.01-1.08; and Output Demands: proportional OR = 1.06, 95% CI = 1.02-1.10). CONCLUSIONS: Our findings suggest that pain-related fear is an important factor related to presenteeism among eldercare workers with LBP. This article is protected by copyright. All rights reserved. PMID- 30289191 TI - Neutral mechanisms and niche differentiation in steady-state insular microbial communities revealed by single cell analysis. AB - In completely insular microbial communities, evolution of community structure cannot be shaped by the immigration of new members. In addition, when those communities are run in steady state, the influence of environmental factors on their assembly is reduced. Therefore, one would expect similar community structures under steady-state conditions. Yet, in parallel setups, variability does occur. To reveal ecological mechanisms behind this phenomenon, five parallel reactors were studied at the single-cell level for about 100 generations and community structure variations were quantified by ecological measures. Whether community variability can be controlled was tested by implementing soft temperature stressors as potential synchronizers. The low slope of the lognormal rank-order abundance curves indicated a predominance of neutral mechanisms, i.e., where species identity plays no role. Variations in abundance ranks of subcommunities and increase in inter-community pairwise beta-diversity over time support this. Niche differentiation was also observed, as indicated by steeper geometric-like rank-order abundance curves and increased numbers of correlations between abiotic and biotic parameters during initial adaptation and after disturbances. Still, neutral forces dominated community assembly. Our findings suggest that complex microbial communities in insular steady-state environments can be difficult to synchronize and maintained in their original or desired structure, as they are non-equilibrium systems. PMID- 30289192 TI - Factors affecting TST level in patients undergoing dialysis: a multicenter study. AB - INTRODUCTION: The risk of TB is increased in patients with chronic kidney disease (CKD) when compared with individuals with normal renal function. We aimed to determine tuberculin skin test (TST) response and the factors which might affect the response in patients with CKD undergoing dialysis in this study. METHODS: The purified protein derivative solution was administered to the patients and the diameter of induration was measured. Additionally, the age, gender and smoking status of the patients were interrogated. Comorbidities were recorded both by patients' self-reports and data from the hospital files. The number of Bacille Calmette-Guerin (BCG) scars was recorded by checking both shoulders. FINDINGS: The study was conducted with a total of 371 patients (194 men and 177 women). The mean age was 60.09 +/- 15.88, TST was 6.99 +/- 6.9, duration of dialysis was 4.44 +/- 4.5 (3.8-0.1,24). A total of 229 patients have comorbodities (61.7%, the most frequent was hypertension). Logistic regression model was performed. Gender, vitamin D treatment and high parathormone (PTH) levels remained in the final stage of the analysis and vitamin D intake and PTH levels were detected to be statistically significant (P = 0.002, 0.007, respectively). DISCUSSION: This study is the first study which showed a correlation between TST negativity and increased PTH levels and receiving vitamin D treatment. Starting from this point, it was concluded that PTH may suppress the immune system and especially cellular immunity. PMID- 30289193 TI - Mycoviruses mediate mycotoxin regulation in Aspergillus ochraceus. AB - To date, no demonstration of a direct correlation between the presence of mycoviruses and the quantitative or qualitative modulation of mycotoxins has been shown. In our study, we transfected a virus-free ochratoxin A (OTA)-producing isolate of Aspergillus ochraceus with purified mycoviruses from a different A. ochraceus isolate and from Penicillium aurantiogriseum. Among the mycoviruses tested, only Aspergillus ochraceus virus (AoV), a partitivirus widespread in A. ochraceus, caused a specific interaction that led to an overproduction of OTA, which is regulated by the European Commission and is the second most important contaminant of food and feed commodities. Gene expression analysis failed to reveal a specific viral upregulation of the mRNA of genes considered to play a role in the OTA biosynthetic pathway. Furthermore, AoOTApks1, a polyketide synthase gene considered essential for OTA production, is surprisingly absent in the genome of our OTA-producing isolate. The possible biological and evolutionary implications of the mycoviral regulation of mycotoxin production are discussed. PMID- 30289194 TI - Migration of retrobulbar wooden foreign body between diagnostic imaging and surgical extraction in a German shepherd dog. AB - A 2-year-old, male castrated German shepherd dog was presented to the University of Tennessee Veterinary Medical Center (UTVMC) with periorbital swelling and conjunctival mucopurulent discharge 2 days following removal of a twig from the medial canthus by the owner. Diagnostic imaging was pursued due to the suspicion of a retrobulbar foreign body (FB). A cylindrical FB approximately 3.0 cm in length and 1.0 cm in diameter with concentric rings, suspected to be wooden material, was identified on computed tomography (CT) imaging. An attempt to remove the FB via a stab incision using ultrasound guidance was unsuccessful, and postmanipulation ultrasound confirmed the FB position was unchanged. An exploratory orbitotomy was performed, using the acquired CT images for guidance in locating the FB; however, the FB was not present at the predicted site. The CT imaging was repeated and showed that the FB had migrated rostrally approximately 3.0 cm, compared to the originally acquired study and its same location during attempted ultrasound-guided removal. A combination of CT-guided needle placement and contrast injection was then used with repeat imaging in an attempt to better localize the FB and its soft tissue tract. The dog was taken back into the operating room, and the wooden FB was successfully removed. PMID- 30289195 TI - Prospective monitoring of after-hours nursing and technologist support calls to a regional Canadian home hemodialysis program. AB - INTRODUCTION: Increasing renal care providers offer home hemodialysis (HD) as a modality choice. There is considerable variation in the provision of after-hours on-call support for self-dialyzing patients and no literature describing the utility of this service. In this prospective, observational study we sought to monitor and classify the number and nature of interactions between home patients and our on-call nurses and technologists, and enumerate the number of adverse events averted by the availability of on-call staff. METHODS: Our home HD unit provided 24-hour on-call patient support and during a 4-month period in 2012, we prospectively monitored all patient calls to this service. The nature of the calls was logged as nursing-related vs. technical. Call outcomes were classified according to whether patients were able to initiate/resume their treatments or whether additional interventions were required. FINDINGS: During this period, our program cared for 58 home HD patients. Nurses fielded 172 calls and dealt with 239 issues. One hundred nine (46%) were clinical issues including 5 (2%) of a serious nature involving potential harm; 67 (28%) related to machine setup or alarms, 36 (15%) required a technologist to resolve, and 27 (11%) were deemed non urgent. One hundred six issues were directed to technologists in 99 calls. Issues pertained to machine malfunction (45 calls-43%), machine set-up and alarms (25 calls-24%), or the water system (24 calls-23%). Only 12 calls (11.3%) were not of a technical nature. Nursing and technologist support allowed patients to initiate or continue their treatment 75% and 71% of the time, respectively. DISCUSSION: Home HD on-call services provide patients support to successfully continue their dialysis treatments by troubleshooting clinical and technical aspects of dialysis and by averting potential adverse events. PMID- 30289196 TI - Psychological distress, role, and identity changes in mothers following a diagnosis of cancer: A systematic review. AB - OBJECTIVE: To systematically review findings of the impact of cancer diagnosis and treatment on mothers' psychological well-being, roles, and identity and to explore the psychosocial factors that contribute to mothers' psychological well being. METHODS: Six databases were searched for research articles and theses exploring the association between the impact of cancer diagnosis and treatment on mothers' psychological well-being, identity, and role, and the psychosocial factors contributing to mothers' psychological distress regardless of their cancer type and stage. The Mixed-Method Appraisal Bias Tool was used to assess the selected studies' methodological quality. RESULTS: A total of 30 qualitative, quantitative, and mixed-method studies were deemed eligible for inclusion. Most studies reported that mothers experienced significant psychological distress, changes to or loss of parenting efficacy, maternal identity, and role. Psychosocial factors that contributed to mothers' distress included mothers' young age, presence of metastases, lower parenting efficacy, fear of cancer recurrence, higher illness intrusiveness, and lack of appropriate support. Four main themes emerged from the qualitative studies: psychological impact of cancer on mothers, changes in maternal identity and role, relationship changes and concerns for their children, and meaning-making in cancer experience. CONCLUSIONS: Changes in mothers' psychological well-being, role, and identity occurred across cancer diagnoses, treatment, and recovery trajectories. The evidence suggests that mothers may benefit from continued and tailored psychosocial support to cope with these challenges, even after treatment is completed. Further studies with improved methodological quality are needed to explore these issues in depth. PMID- 30289197 TI - Iron- and aluminium-induced depletion of molybdenum in acidic environments impedes the nitrogen cycle. AB - Anthropogenic nitrate contamination is a serious problem in many natural environments. Nitrate removal by microbial action is dependent on the metal molybdenum (Mo), which is required by nitrate reductase for denitrification and dissimilatory nitrate reduction to ammonium. The soluble form of Mo, molybdate (MoO4 2- ), is incorporated into and adsorbed by iron (Fe) and aluminium (Al) (oxy) hydroxide minerals. Herein we used Oak Ridge Reservation (ORR) as a model nitrate-contaminated acidic environment to investigate whether the formation of Fe- and Al-precipitates could impede microbial nitrate removal by depleting Mo. We demonstrate that Fe and Al mineral formation that occurs as the pH of acidic synthetic groundwater is increased, decreases soluble Mo to low picomolar concentrations, a process proposed to mimic environmental diffusion of acidic contaminated groundwater. Analysis of ORR sediments revealed recalcitrant Mo in the contaminated core that co-occurred with Fe and Al, consistent with Mo scavenging by Fe/Al precipitates. Nitrate removal by ORR isolate Pseudomonas fluorescens N2A2 is virtually abolished by Fe/Al precipitate-induced Mo depletion. The depletion of naturally occurring Mo in nitrate- and Fe/Al contaminated acidic environments like ORR or acid mine drainage sites has the potential to impede microbial-based nitrate reduction thereby extending the duration of nitrate in the environment. PMID- 30289198 TI - Long-term efficacy of novel therapies in moderate-to-severe plaque psoriasis: a systematic review and network meta-analysis of PASI response. AB - BACKGROUND: Patients with moderate-to-severe psoriasis require long-term treatment, yet few trials compare outcomes beyond a short-term induction period. Quantitative comparisons of long-term outcomes in patients with psoriasis are limited. To our knowledge, no network meta-analysis (NMA) of such data has been performed. OBJECTIVE: To compare novel systemic therapies, both biologic and non biologic, approved for moderate-to-severe psoriasis by conducting a systematic review (SR) and NMA of Psoriasis Area and Severity Index (PASI) outcomes measured at or around 1 year. METHODS: An SR was conducted to identify studies reporting PASI 75, PASI 90 and PASI 100 responses. Feasibility of an NMA on maintenance phase endpoints was assessed and sources of heterogeneity considered. Data appropriate for analysis were modelled using a Bayesian multinomial likelihood model with probit link. Wherever possible, data corresponding to an intention-to treat approach with non-responder imputation were used. RESULTS: Twenty-four studies reporting outcomes at 40-64 weeks were identified, but heterogeneity in study design allowed synthesis of only 17. Four 52-week randomized controlled trials (RCTs) comprised the primary analysis, which found brodalumab was significantly more efficacious than secukinumab, ustekinumab and etanercept. Secukinumab was also more efficacious than ustekinumab and both outperformed etanercept. In a secondary analysis, evidence from 13 additional studies and 4 further therapies (adalimumab, apremilast, infliximab and ixekizumab) was included by comparing long-term outcomes from active interventions to placebo outcomes extrapolated from induction. Results were consistent with the primary analysis: brodalumab was most effective, followed by ixekizumab and secukinumab, then ustekinumab, infliximab and adalimumab. Etanercept and apremilast had the lowest expected long-term efficacy. Results were similar when studies with low prior exposure to biological therapies were excluded. CONCLUSION: Results suggest that brodalumab is associated with a higher likelihood of sustained PASI response, including complete clearance, at week 52 than comparators. Further long term active-comparator RCT data are required to better assess relative efficacy across therapies. PMID- 30289199 TI - Neuropathy and inflammation in diabetic bone marrow. AB - Diabetes impairs the bone marrow (BM) architecture and function as well as the mobilization of immature cells into the bloodstream and number of potential regenerative cells. Circadian regulation of bone immature cell migration is regulated by beta-adrenergic receptors, which are expressed on haematopoietic stem cells, mesenchymal stem cells, and osteoblasts in the BM. Diabetes is associated with a substantially lower number of sympathetic nerve terminal endings in the BM; thus, diabetic neuropathy plays a critical role in BM dysfunction. Treatment with mesenchymal stem cells, BM mononuclear cells, haematopoietic stem cells, and stromal cells ameliorates the dysfunction of diabetic neuropathy, which occurs, in part, through secreted neurotrophic factors, growth factors, adipokines, and polarizing macrophage M2 cells and inhibiting inflammation. Inflammation may be a therapeutic target for BM stem cells to improve diabetic neuropathy. Given that angiogenic and neurotrophic effects are two major barriers to effective diabetic neuropathy therapy, targeting BM stem cells may provide a novel approach to develop these types of treatments. PMID- 30289200 TI - Clinical characteristics and risk factors for stent-stone complex formation following biliary plastic stent placement in patients with common bile duct stones. AB - BACKGROUND: Stent-stone complex (SSC) formation is one of the complications of endoscopic biliary stent placement. This study aimed to clarify the clinical characteristics and risk factors for SSC formation following plastic stent (PS) placement in patients with common bile duct (CBD) stones. METHODS: We retrospectively reviewed the charts of 78 patients with CBD stones who had undergone 107 biliary stent placements as palliative treatment. Demographic, historical, and stent-related data were collected and analyzed. RESULTS: At PS removal, SSC formations were observed in 18% of the 107 cases (SSC group) studied and not in the remaining 82% (non-SSC group). The duration of PS placement was significantly longer in the SSC group. The increase in CBD diameter during the stenting period as well as the incidence of cholangitis at PS removal was significantly greater in the SSC group. Multivariate analysis identified long term (>=301 days) PS placement and the increase in CBD diameter during the stenting period as independent factors for SSC formation. CONCLUSIONS: Long-term PS placement induces a risk of SSC formation in patients with CBD stones. The increase in diameter of CBD during the period of PS placement is a predictive factor for SSC formation in this situation. PMID- 30289201 TI - New tools for high-throughput expression of fungal secretory proteins in Saccharomyces cerevisiae and Pichia pastoris. AB - Heterologous protein expression in yeast, mostly in Saccharomyces cerevisiae and Pichia pastoris, is a well-established and widely used technique. It typically requires the construction of an expression vector in Escherichia coli containing the foreign gene and its subsequent transformation into yeast. Although simple, this procedure has important limitations for the expression of large numbers of proteins, that is, for the generation of protein libraries. We describe here the development of a novel system for the easy and fast expression of heterologous proteins both in S. cerevisiae and in P. pastoris, under the control of the GAL1 and AOX1 promoters respectively. Expression in S. cerevisiae requires only the transformation of yeast cells with an unpurified PCR product carrying the gene to be expressed, and the expression of the same gene in P. pastoris requires only the isolation of the plasmid generated in S. cerevisiae and its transformation into this second yeast, thus making this system suitable for high-throughput projects. The system has been tested by the extracellular expression of 30 secretory fungal proteins. PMID- 30289202 TI - How Does Oocyte Uptake Occur? A Macroscopic Study of the Ovarian and Oviductal Modifications for Egg Capture in the Coral-Snake Micrurus corallinus. AB - The processes of follicular development, ovulation, egg capture, and egg transport vary among vertebrates. Therefore, analysis of the reproductive tract of several lineages is needed for understanding the evolutionary changes of the reproductive system. In turtles, the ovulated eggs are released into the coelomic cavity and taken up by one of the two oviducts, a phenomenon called extrauterine migration of eggs. However, the process of egg uptake in lizards is different. The egg is ovulated directly into the infundibulum, and oocyte uptake by the contralateral oviduct rarely occurs. The same pattern has been hypothesized to occur in snakes. To test this hypothesis, we analyzed the reproductive tract of female Micrurus corallinus preserved in zoological collections. We examined the anatomical characteristics of the infundibulum and ovary and compared the reproductive output between the ovaries to verify the mechanism of egg capture and the anatomical viability of extrauterine migration of eggs. The reproductive output of the right ovary was higher than that of the left ovary, and the higher number of eggs in the right oviduct is due exclusively to the production of the ipsilateral ovary. Several anatomical features prevent extrauterine migration of eggs, including the asymmetry of the reproductive system, the arrangement of the ovarian follicles in a single row, and the formation of a wrapping around the ovary and infundibulum by the visceral pleuroperitoneum membrane (preventing against ectopic eggs). Therefore, the hypothesis of egg capture by the contralateral oviduct is anatomically infeasible in M. corallinus and possibly in other snakes. Anat Rec, 301:1936-1943, 2018.

AB - Primary cilia are small organelles projecting from the cell surface of many cell types. They play a crucial role in the regulation of various signaling pathway. In this study, we investigated the importance of cilia for heart development by conditionally deleting intraflagellar transport protein Ift88 using the col3.6 cre mouse. Analysis of col3.6;Ift88 offspring showed a wide spectrum of cardiovascular defects including double outlet right ventricle and atrioventricular septal defects. In addition, we found that in the majority of specimens the pulmonary veins did not properly connect to the developing left atrium. The abnormal connections found resemble those seen in patients with total anomalous pulmonary venous return. Analysis of mutant hearts at early stages of development revealed abnormal development of the dorsal mesocardium, a second heart field-derived structure at the venous pole intrinsically related to the development of the pulmonary veins. Data presented support a crucial role for primary cilia in outflow tract development and atrioventricular septation and their significance for the formation of the second heart field-derived tissues at the venous pole including the dorsal mesocardium. Furthermore, the results of this study indicate that proper formation of the dorsal mesocardium is critically important for the development of the pulmonary veins. Anat Rec, 2018.

AB - Organogenesis is a complex coordinated process of cell proliferation, growth, migration, and apoptosis. Differential growth rates, particularly during cardiogenesis, play a role in establishing morphology. Studies using stereological and cell sorting methods derive averages of morphogenetic parameters for an organ. To understand tissue composition and differential growth, the researcher must determine a number of morphogenetic parameters in the developing organ. Such measurements require sectioning to enable identification of organ borders, tissue components and cell types, three-dimensional (3D) reconstruction of sections to visualize morphology and a 3D-measurement scheme to build local morphogenetic information. Although thick the section confocal microscopy partially solves these issues, information loss at the section surface hampers the reconstruction of 3D morphology. Episcopic imaging provides the correct morphology but lacks histological procedures to identify multiple cell types. The 3D-measurement scheme is based on systematic sampling, with overlapping sample volumes, of the entire organ in the aligned image stack. For each sample volume, morphogenetic variables are calculated and results projected back to the cube (boxel) at the sample volume center. Boxel size determines spatial resolution of the final quantitative 3D-reconstruction whereas size of the sample volume determines the precision of the morphogenetic information. The methods described here can be used to measure tissue volume, proliferation and cell size, to determine contribution and distribution of cell types in a tissue and to display this information in a quantitative 3D-reconstruction.

PMID- 30289207 TI - Current status and future trends on automated multidimensional separation techniques employing sorbent-based extraction columns. AB - Determination of target analytes present in complex matrices requires a suitable sample preparation approach to efficiently remove the analytes of interest from a medium containing several interferers while at the same time preconcentrating them aiming to improve the output signal detection. Online multidimensional solid phase separation techniques have been widely used for the analysis of different contaminants in complex matrices such as food, environmental, and biological samples, among others. These online techniques usually consist of two steps performed in two different columns (extraction and analytical column), the first being employed to extract the analytes of interest from the original medium and the latter to separate them from the interferers. The extraction column in multidimensional techniques presents a relevant role since their variations as building material (usually a tube), sorbent material, modes of application, and so on can significantly influence the extraction success. The main features of such columns are subject of constant research aiming improvements directly related to the performance of the separation techniques that utilize multidimensional analysis. The present review highlights the main features of extraction columns online coupled to chromatographic techniques, inclusive for in tube solid-phase microextraction, online solid phase and turbulent flow, aiming the determination of analytes present at very low concentrations in complex matrices. It will critically describe and discuss some of the most common instrumental set up as well as comments on recent applications of these multidimensional techniques. Besides that, the authors have described some properties and enhancements of the extraction columns that are used as first dimension on these systems, such as type of column material (poly (ether ether ketone), fused silica, stainless steel, and other materials) and the way that the extractive phase is accommodated inside the tubing (filled and open tubular). Practical applications of this approach in fields such as environment, food, and bioanalysis are also presented and discussed. PMID- 30289208 TI - Neuropil Distribution in the Anterior Cingulate and Occipital Cortex of Artiodactyls. AB - Relatively little neuroscience research has been focused on artiodactyls. Recent observations of complex social interactions in domestic and wild species suggest that analyses of artiodactyl brain anatomy would be of comparative value. In this study, we examined how the distribution of cortical neuropil space (a proxy for connectivity) varies across representative members of this diverse clade. Using image analysis techniques, we quantified the neuropil space in the anterior cingulate cortex (ACC) and the occipital (putative primary visual) cortex (OC) of 12 artiodactyl species from adult specimens. Additionally, we conducted a preliminary investigation of variation in ACC neuropil space in a developmental series of five white-tailed deer (Odocoileus virginianus). Results indicate a consistent pattern of greater neuropil space in the ACC in comparison to the OC among all species, and a gradual increase in ACC neuropil space toward maturity in the white-tailed deer. Given the taxa that have the greatest cortical neuropil space, we hypothesize that such enhanced connectivity might be needed to support behaviors such as group foraging and attentiveness to conspecifics. These results help advance a broader understanding of diversity in neural circuitry in artiodactyls and point to the need for more in-depth comparisons of cortical neuron morphology and organization in this relatively understudied taxonomic group.

AB - With the bromodomain (BRD) inhibitor JQ1, a remarkable success story of BRD4 as a novel drug target has been set off that yielded many anti-cancer drugs that are now in clinical trials. But not all of the great prospects of BRDs as drug targets may become true. First evaluations of ongoing clinical trials revealed that treatment with BET-inhibitors can be accompanied with significant toxic side effects and the validation of the therapeutic benefit of BET-inhibitors compared to existing therapies is still pending. New strategies that may overcome possible obstacles in BRD drug discovery include combination therapies with other agents, dual target inhibitors, and proteolysis targeting chimeras (PROTACs). Furthermore, non-BET proteins seem promising drug targets as well. Most recently, BRDs have been identified as putative targets to treat parasitic diseases such as malaria. Milestones in BRD drug discovery are reviewed and promising new developments are evaluated. PMID- 30289210 TI - Immunopathogenesis of ophthalmological paraneoplastic syndromes: Recent findings. AB - The aim of this study was to summarize the current knowledge of paraneoplastic syndromes involving eyes. The main interest was the immunopathogenesis of the abovementioned entities. A web search was conducted using Medline, Web of Science and Scopus engines. Key words concerning ocular paraneoplastic syndromes (OPS) such as: "ocular paraneoplastic syndrome", "cancer-associated retinopathy", "cancer-associated cone dysfunction", "melanoma-associated retinopathy", "bilateral diffuse uveal melanocytic proliferation", and "paraneoplastic optic neuritis" were combined with "immunology", "immune response", "antibodies", or "autoantibodies". Numerous papers were found as a result of "ocular paraneoplastic syndrome" search and many of them matched the chosen criteria. We focused on the most recent papers - published in the last 5 years - and eventually, 92 items were found. Only several papers from each detailed category fulfilled both OPS and immunologic criteria. Site-specific paraneoplastic syndromes still remain a difficult clinical challenge. The immunopathogenesis of some of them seems to be more complex than previously thought. PMID- 30289211 TI - An evaluation of the effect on lower extremity fracture healing of collagen-based fusion material containing 2 different calcium phosphate salts: An experimental rat model. AB - BACKGROUND: Collagen-based synthetic bone grafts which contain tricalcium phosphate (TCP) and hydroxyapatite (HA), and collagen-based synthetic bone grafts containing only TCP have some advantages compared to autografts. Therefore, these grafts are frequently used to fill bone defects and pseudoarthrosis. OBJECTIVES: The aim of this study was to evaluate and compare the clinical, radiological and histopathological effects of TCP-HA and TCP alone + Type-1 collagen in healing lower extremity fractures in a pseudoarthrosis model in rat femurs. MATERIAL AND METHODS: A total of 36 female Wistar rats were randomly separated into 4 groups. Group 1 (n = 10) was the control group. A femur pseudoarthrosis model was created in Groups 2, 3 and 4. On the 90th day after the 1st surgery in Group 2 (n = 10), TCP-HA + Type-1 collagen was applied, in Group 3 (n = 10), TCP alone + type-1 collagen was applied, and in Group 4 (n = 6, the placebo group), saline solution was applied. Fixation was performed with an intramedullar pin. After 60 days and clinical and radiological scoring, all animals were sacrificed and a histopathological evaluation of the pseudoarthrosis areas was conducted. RESULTS: In all the clinical, radiological and histopathological measurements used in the evaluations of the differences between the groups, a higher rate of union was determined in Group 2 (TCP-HA). No significant difference was determined between Group 3 and Group 4 in terms of union rates. CONCLUSIONS: The clinical, radiological and histopathological results of this study showed that TCP alone was less effective than TCP-HA in the union of a femur pseudoarthrosis model in rats. The reason for this difference was considered to be hydroxyapatite (HA). PMID- 30289212 TI - Gastroesophageal reflux disease: current views and prospects.

The need for a multidisciplinary approach to the development of combined treatment programs is underlined taking into account the multifactorial pathogenesis of obesity. A combination of optimal physical activity and diet therapy with active personal involvement in the process of recovery is accentuated among the priority areas of excess body weight correction, as well as the treatment and prevention of obesity. It is shown that the physical rehabilitation should focus on the individualization of the physical exertion, its adequate dosing and intensity control using heart rate monitors to ensure the safety and effectiveness of the training sessions. The article also presents data on the effectiveness of rational medical and other types of treatment of obesity when the adjustment of physical activities and nutrition is insufficient. In particular, the results of the world's largest observation program of safe weight loss for the treatment of patients with alimentary obesity held in Russia from 2012 to 2015 are described.

AB - The principles of primary prevention of bleeding from esophageal varices in patients with liver cirrhosis are discussed with reference to the stage ofportal hypertension. The information was collectedfrom the PubMed database, Google Scholar retrieval system, Cochrane reviews, and lists of references from relevant publications for 1980-2015 using the key words "bleeding from esophageal varices", "prophylaxis", "portal hypertension". Inclusion criteria were confined to primary prophylaxis of bleeding from esophageal varices in patients with liver cirrhosis. The analysis showed that the drugs of choice for primary prophylaxis of bleeding from esophageal varices in patients with liver cirrhosis are non selective beta-adrenoblockers, but their application is indicated only in case of clinicallyl significant portal hypertension in patients with large and mediumsize esophageal varices. When the use of these drugs is contraindicated, endoscopic ligation of esophageal varices can be recommended. PMID- 30289216 TI - Personified strategy for the correction of cardiometabolic risk factors in the alien population of the Arctic. AB - Aim. To estimate the efficacy and prognostic value of individual consulting in Far North inhabitants during a 5 year survey. Materials and methods. 125 patients with metabolic syndrome were included in the study (24.8% women, 24.8% men, age median 45 years (39-48); p > 0.05). All the participants were divided into 2 groups dependence on the consulting frequency in the framework of the non surgical body mass reduction programs (group 1 - single consulting, group 2 - repeated consultings in 12 months). Results. Individual consulting of patients with MS within 3 months after the onset of the study allowed the target body mass to be achieved in 50% of the patients in association with the reduction of atherogenic lipid fractions (p < 0,05), insulin resistance (p < 0,05), inflammation markers, hemostasis disorders markers (p < 0,05) and decrease in the number of patients with behavioral risk factors. Repeated educational module increased the relative probability 1,9 (95% CI 1,03-3,6) and odds ratio - 2.4 (95% CI 1,01-5,4) of body mass maintenance within 24 months and also reduced the risk of type 2 DM development (Cox's F-Test: F = 2,7; p = 0,041) and atherogenicity of lipid profile after 5 year observations. Conclusion. Our results proves the necessity of active utilization of educational modules at least as often as once a year. For the successful use of these modules based at outpatient facilities of the Far North it is necessary to include a dietologist in the staff of prophylactic departments which encounters difficulty under the modern funding mode. PMID- 30289218 TI - The role of cytokine gene polymorphism in the formation of arterial hypertension associated with metabolic syndrome. AB - We investigated the association of polymorphisms of genes tumor necrosis factors and their receptors (-308G/A TNFa, +250A/G Lta, +36 A/G TNFR1, +1663 A/G TNFR2) with the predisposition to the development of essential hypertension (EH) and the features of its clinical course in patients with metabolic syndrome. It has been demonstrated that the molecular genetic marker +36G TNFR1 (OR=1,25) is involved in the formation EH in individuals with metabolic syndrome. The risk of stage III EH in patients with metabolic syndrome is enhanced by genetic variants -308GA TNFa (OR=2,72), -308A TNFa (OR=2,72), +250G Lta (OR=1,80), and combinations thereof -308A TNFa with +1663G TNFR2 (OR=3,85), +250G Lta with +36G TNFR1 (OR=3,85), +250G Lta with +1663G TNFR2 (OR=3,85) while protective properties are inherent in -308GG TNFa (OR=0,32), +250AA Lta (OR=0,45), -308G TNFa (OR=0,37), +250A Lta (OR=0,56) and a combination of genetic markers -308GG TNFa with +250A Lta (OR=0,31), -308G TNFa with +250AA Lta (OR=0,39), -308G TNFa with +250A Lta (OR=0,31).

AB - The aim of this study was to investigate the efficiency of metabolic therapy in correction of cognitive impairment in patients with type 2 diabetes. We undertook the analysis of results of the treatment of cognitive dysfunction in 80 patients with a diagnosis of type 2 diabetes. All patients received basic hypoglycemic therapy. 32 patients (study group) received in addition to the basal glucose lowering therapy daily intravenous infusion of 10 mlcytoflavindiluted in 200 ml of a 0.9% sodium chloride solution for 10 days, followed by 2 tablets b.i.d. for 25 days.The group of comparison consisted of 29 patients given in addition to the basal glucose-lowering therapy daily intravenous infusion of 24 ml (600 mg) thioctacid diluted in 200 mL of a 0.9% sodium chloride solution for 10 days. Thereafter, they received 1 tablet of thioctacid BV once daily for 30 days. The control group consisted of 19 patients who received basic hypoglycemic therapy without additional metabolic therapy.Inclusion of cytoflavin in the combined treatment of patients with type 2 diabetes ensured a more effective correction of cognitive impairment. There was a statistically significant improvement in optical-spatial activities (p = 0.001), attention (p = 0.001), abstract thinking (p = 0.046), and memory (p<0.001) compared to those in other groups, according to the MOS test. Positive dynamics was expressed as the improvement of the optical spatial activities by 9,8 +/- 10,3%, attention by 13,5 +/- 11,8%, abstract thinking by 7,0 +/- 8,9%, and memory by 23.0 +/- 14 6%. The study of variations of the serum level of brain neurotrophic factor (BDNF) over time during the treatment with metabolic preparations reveal edits statistically significant increase (p = 0.002) in the patients treated with cytoflavin compared with comparison (p = 0.139) and control (p = 0.078) groups. These results suggest the influence of cytoflavin on the processes of neuroplasticity under conditions of hyperglycemia, improvement of cerebral microcirculation and cerebroprotective action of this medication.

Special attention is given to such issues as the doctor's authority, patient's confidence, and professional preparation of the first patient's visit. The authority of the physician depends on his professional skills and moral qualities, such as sense of duty, humanism, and love for his occupation. The causes behind failed relationships between the doctor and the patient are considered with special reference to deontological flaws on the part of the physician.

PMID- 30289235 TI - Three-Dimensional Nanostructured Palladium with Single Diamond Architecture for Enhanced Catalytic Activity. AB - Fuel cells are a key new green technology that have applications in both transport and portable power generation. Carbon-supported platinum (Pt) is used as an anode and cathode electrocatalyst in low-temperature fuel cells fueled with hydrogen or low-molecular-weight alcohols. The cost of Pt and the limited world supply are significant barriers to the widespread use of these types of fuel cells. Comparatively, palladium has a 3 times higher abundance in the Earth's crust. Here, a facile, low-temperature, and scalable synthetic route toward three dimensional nanostructured palladium (Pd) employing electrochemical templating from inverse lyotropic lipid phases is presented. The obtained single diamond morphology Pd nanostructures exhibited excellent catalytic activity and stability toward methanol, ethanol, and glycerol oxidation compared to commercial Pd black, and the nanostructure was verified by small-angle X-ray scattering, scanning tunneling electron microscopy, and cyclic voltammetry. PMID- 30289236 TI - Gene Dysfunction Mediates Immune Response to Dopaminergic Degeneration in Parkinson's Disease. AB - Many publications reported that genetic dysfunction mediates abnormal immune responses in the brain, which is important for the development of neurodegenerative diseases, especially for Parkinson's disease (PD). This immune disorder results in subsequent inflammatory reaction, which stimulates microglia or other immune cells to secrete cytokines and chemokines and disturbs the proportion of peripheral blood lymphocyte subsets contributing to dopaminergic (DA) neuron apoptosis. Furthermore, the abnormal immune related signal pathways caused by genetic variants promote chronic inflammation destroying the blood brain barrier, which allows infiltration of different molecules and blood cells into the central nervous system (CNS) exerting toxicity on DA neurons. As a result, the inflammatory reaction in the CNS accelerates the progression of Parkinson's disease and promotes alpha-synuclein aggregation and diffusion among DA neurons in the procession of Parkinson's disease. Thus, for disease evaluation, the genetic mediated abnormal immune response in PD may be assessed based on the multiple immune molecules and inflammatory factors, as well as the ratio of lymphocyte subsets from PD patient's peripheral blood as potential biomarkers. PMID- 30289237 TI - Tuning Microstructures of Graphene to Improve Power Capability of Rechargeable Hybrid Aqueous Batteries. AB - Low conductivity and structural degradation of LiMn2O4 lead to poor power capability and severe capacity fading of hybrid aqueous Zn/LiMn2O4 battery. Here, we propose an effective strategy by tuning the microstructures of graphene to optimize its electrical and interfacial properties and electrode dynamics of LiMn2O4/graphene cathodes, which successfully prompt significant improvements in electrical conductivity and structural stability, thus essentially leading to a promising electrochemical performance. More importantly, it reveals different electrochemical properties prompted by different conductivity, which mainly depends on the microstructures of graphene. This dependence is due to the influence of electronic channels and conductive paths on the conductivity of LiMn2O4/graphene electrodes. A well-designed mesoporous graphene composed of about two graphene-layers exhibits an excellent high-rate performance; even after 300 cycles, a highly reversible capacity of 75 mAh g-1 is retained at 4C rate. The results of this study suggest that the structural tuning of electronic channels of graphene can be used as an effective means to improve the performance of LiMn2O4 cathodes in hybrid aqueous batteries. PMID- 30289238 TI - Ultraviolet Irradiation Treatment for Enhanced Sodium Storage Performance Based on Wide-Interlayer-Spacing Hollow C@MoS2@CN Nanospheres. AB - The photochemistry and sodium storage process have been generally considered as two separated approaches without strong connection. Here, ultraviolet (UV) irradiation was applied to sodium-ion batteries to improve the electrochemical performance of MoS2-based composites. C@MoS2@CN nanospheres consist of double protective structures, including inner hollow carbon spheres with a thin wall (C) and outer N-doping carbon nanosheets (CNs) derived from polydopamine. The special nanostructure possesses the virtues such as wide-interlayer spacing, flexible feature with great structure integrity, and rich active sites, which endow the fast electron transfer and shorten the ion diffusion pathways. Under the excitation of UV-light, intense electrons and holes are accumulated within MoS2 based composites. The excited electrons can promote the preinsertion of Na+. More importantly, dense electrons promote the electrolyte to decompose and hence form a stable solid electrolyte interphase in advance. After UV-light irradiation treatment in the electrolyte, the initial Coulombic efficiency of C@MoS2@CN electrodes increased from 48.2 to 79.6%, and benefiting from the fine nanostructure, the C@MoS2@CN electrode with UV irradiation treatment delivered a great rate performance 116 mAh g-1 in 20 s and super cycling stability that 87.6% capacity was retained after 500 cycles at 500 mA g-1. When employed as anode for sodium-ion hybrid capacitors, it delivered a maximum power density of 6.84 kW kg-1 (with 114.07 Wh kg-1 energy density) and a maximum energy density of 244.15 Wh g-1 (with 152.59 W kg-1 power density). This work sheds new viewpoints into the applications of photochemistry in the development of energy storage devices. PMID- 30289239 TI - Application of Electronic Counting Rules for Ligand-Protected Gold Nanoclusters. AB - Understanding special stability of numerous ligand-protected gold nanoclusters has always been an active area of research. In the past few decades, several theoretical models, including the polyhedral skeletal electron pair theory (PSEPT), superatom complex (SAC), and superatom network (SAN), among others, have been developed for better understanding the stabilities and structures of selected ligand-protected gold nanoclusters. This Account overviews the recently proposed grand unified model (GUM) to offer some new insights into the structures and growth mechanism of nearly all crystallized and predicted ligand-protected gold nanoclusters. The main conceptual advancement of the GUM is identification of the duet and octet rules on the basis of the "big data" of 70+ reported ligand protected gold nanoclusters. According to the two empirical rules, the cores of the gold nanoclusters can be regarded as being composed of two kinds of elementary blocks (namely, triangle Au3 and tetrahedron Au4), each having 2 e closed-shell valence electrons (referred as Au3(2 e) and Au4(2 e)), as well as the secondary block (icosahedron Au13) with 8 e closed-shell valence electrons (referred as Au13(8 e)). The two elementary blocks (Au3(2 e) and Au4(2 e)) and the secondary block (Au13(8 e)), from electron counting point of view, can be regarded as an analogy of the highly stable noble-gas atoms of He and Ne, respectively. In each elementary block, the Au atoms exhibit three different valence-electron states (i.e., 1 e, 0.5 e, and 0 e), depending on the type of ligands bonded with these Au atoms. Such three valence-electron states are coined as three "flavors" of gold (namely, bottom, middle, and top "flavor"), a term borrowed from the quark model in the particle physics. Upon application of the duet and octet rules with accounting the three valence states of gold atoms, the Au3(2 e), Au4(2 e), and Au13(8 e) blocks can exhibit 10 (denoted as Delta1 Delta10), 15 (denoted as T1-T15), and 91 (denoted as I1-I91) variants of valence states, respectively. When packing these blocks (with distinct electronic states) together, it forms the gold core of ligand-protected gold nanocluster. As such, the special stabilities of the ligand-protected gold nanoclusters are explained based on the local stability of each block. With GUM, rich and complex structures of ligand-protected gold nanoclusters have been analyzed through structure anatomy. Moreover, the growth of these clusters can be simply viewed as sequential addition of the blocks, rather than as addition of the gold atoms. Another useful application of the GUM is to analyze the structural isomerism. The three types of isomerism for the gold nanoclusters, i.e., core, staple, and complex isomerism, can be considered as an analogy of chain, point, and functional isomerism (known in organic chemistry), respectively. GUM can be applied to predict new clusters, thereby guiding experimental synthesis. Indeed, a number of ligand-protected gold nanoclusters with high stabilities were rationally designed based on the GUM.

AB - Hierarchical nanosheet-based nanotubes are very attractive because their unique structure endows them with large surface areas and exposes massive active sites for functional applications. We herein demonstrate a facile one-pot hydrothermal approach to fabricate the hierarchical nanosheet-based MS2 (M = Re, Mo, W) nanotubes by using Te nanowires as sacrificial templates. The hierarchical nanotubes show tube channels of ~30 nm and hierarchical channel walls with a tunable thickness of up to ~50 nm. As exemplified for application in Li-ion and Na-ion batteries, the ReS2 hierarchical nanotubes exhibit excellent specific capacities (1137 mA h g-1 for Li-ion batteries and 375 mA h g-1 for Na-ion batteries at 0.1 A g-1 after 100 cycles), good cycling stabilities, and high rate capabilities, demonstrating their promising applicability in rechargeable batteries. This work may open up new opportunities for further exploration of new types of hierarchical nanostructures for applications, e.g., in catalysis, energy chemistry, and gas adsorption and separation.

AB - The optical and electronic properties of semiconductor quantum dots (QDs) make them attractive candidates for applications in photovoltaics, spintronics, photocatalysis, and optoelectronics. Understanding how to control the flow of charge in QD assemblies is essential for realizing novel applications. This Account explores some unique characteristics of charge transport in QD dyads, triads, and their assemblies. The emerging features of these assemblies that provide new opportunities to manipulate charge flow at the nanoscale are (1) cascading energy landscapes and band offsets to inhibit charge recombination, (2) electrostatic fields that direct charge flow through QD-QD and QD-conjugated polymer junctions, and (3) QD chirality and chiral imprinting that promotes vectorial electron and spin selective transport. Charge flow kinetics is determined by a combination of familiar electron transfer parameters (reaction free energy, reorganization energy, and electronic coupling), donor and acceptor electronic densities of states, and internal electric fields. Electron transfer and electronic structure theory, combined with kinetic modeling, place the measured kinetics of QD electron transfer donor-acceptor assemblies into a unified conceptual context. The experimental transfer rates measured in these systems depend upon structure and the internal electric fields that are present in the assemblies. A negatively charged donor and positively charged acceptor, for example, facilitates (inhibits) electron (hole) transfer, while an electric field of opposite orientation (reversal of charges) inhibits (promotes) electron (hole) transfer. These and other emerging rules that govern charge flow in NP assemblies provide a strategy to design the directionality and yield of interfacial charge transport. Chirality at the nanoscale can induce spin selective charge transport, providing new ways to direct charge (and spin) flow in QD assemblies. Magnetoresistance and magnetic conductive probe atomic force microscopy experiments show spin selective electron transport for chirally imprinted QD assemblies. Photoinduced electron transfer from achiral donor-QDs to chiral acceptor-QDs depends on the electron spin and chiroptical properties of the acceptor-QDs. These assemblies show transport characteristics that correlate with features of the QDs' circular dichroism spectra, presenting intriguing challenges to theory, and indicating that spectroscopic signatures may assist in the design and diagnosis of functional molecular assemblies. Theoretical and experimental studies of charge transport in well-defined QD assemblies are establishing design principles for vectorial charge transport and are also refining questions surrounding the mechanism and control of these processes. These intensified efforts are forging links between fundamental discoveries regarding mechanism and practical applications for these novel assembled nanostructures.

AB - Antibody-based diagnostic and therapeutic reagents armed with effector molecules such as dyes and drugs offer hope in the battle against cancer. Several site specific conjugation methods have been developed to equip antibodies with such effector molecules, but they tend to be expensive and involve multiple reaction steps. The conjugation of two different effector molecules to a single antibody also remains a major challenge. Here we describe a simple, controlled, and robust method for the dual site-specific conjugation of an antibody with two effector molecules in a single-pot reaction using the self-labeling SNAP and CLIP protein tags. We verified the principle of the method by labeling an epidermal growth factor receptor (EGFR)-specific single-chain antibody fragment (scFv-425) simultaneously with IRDye700 and Alexa-Fluor647. This dual-labeled antibody bound to EGFR+ ovarian cancer cell lines and tissue samples with high specificity, and its phototherapeutic efficacy was confirmed by the selective killing of EGFR+ cells in vitro.

AB - We illustrate that the extent of hydration and consequently the heat of hydration of alkali metal ions can be utilized to control their insertion/deinsertion chemistry in a redox active metal coordination polymer framework (CPF) electrode. The formal redox potential of CPF electrode for cation intercalation is inversely correlated to hydrated ionic radii, with clear distinction between the intercalation of ions across alkali metal series. This leads to noninvasive identification and differentiation of cations in the alkali metal series by utilizing a single sensing platform. PMID- 30289244 TI - Probing Electrocatalysis at Individual Au Nanorods via Correlated Optical and Electrochemical Measurements. AB - A novel analytical methodology based on correlated optical and electroanalytical measurements was developed to probe electrocatalytic reactions at individual nanoparticles (NPs) with well-defined geometries. The developed methodology, Optically Targeted ElectroChemical Cell Microscopy (OTECCM), relies on a combination of optical hyperspectral imaging, to locate individual NPs and provide structural information, and Scanning ElectroChemical Cell Microscopy (SECCM), to provide direct information on the electrochemical behavior of the same NPs. This complementary strategy allows for SECCM measurements to be carried out in a "targeted" fashion, offering significant throughput advantages over conventional, scanning-based approaches. The developed methodology was applied to study the electrocatalytic oxidation of hydrazine at individual Au nanorods (NRs). Correlated electron microscopy investigations were carried out to conclusively demonstrate the ability of the proposed methodology to probe electrochemical reactions at individual NRs. A wide variety in behavior of the individual NRs was observed, with surface reactions at Au playing a prominent role in the observed response. In situ spectroscopic investigations at individual NRs suggest surface restructuring and/or residual ligand desorption leads to significant changes in catalytic activity over time. Results from the correlated electron microscopy investigations as well as the statistical analyses of data obtained for hundreds of individual nanostructures suggest that the gross geometry of a NR is a poor predictor of its electrocatalytic performance. PMID- 30289245 TI - Label-Free, Single-Particle, Colorimetric Detection of Permanganate by GNPs@Ag Core-Shell Nanoparticles with Dark-Field Optical Microscopy. AB - Rapid quantification of permanganate (MnO4-) in aqueous solution with a convenient and sensitive single-particle-detection (SPD) method is demonstrated by dark-field optical microscopy. The design is based on the selective etching of the Ag shell of a glucose-protected GNPs@Ag nanoparticle by MnO4-. In the presence of MnO4-, a noticeable red-shift of localized surface-plasmon resonance (LSPR, from blue to green) together with a tremendous decrease in the extinction coefficient from individual GNPs@Ag nanoparticles is observed. MnO4- can then be quantified by calculating the ratio between the number of green and blue particles on the cover glass surface after the etching process. A linear dynamic range of 0-6 MUM and a limit of detection (LOD) as low as 46 nM were readily achieved, which are much lower than those of spectroscopic measurements in bulk solution. In tap water, a comparable LOD (50 nM) and satisfactory recovery efficiency are demonstrated. As a consequence of these merits, the method demonstrated herein will find promising applications for the ultrasensitive detection of MnO4- under complex milieu in the future. PMID- 30289246 TI - A Slick Solution to a Sticky Problem. PMID- 30289247 TI - Methane Activation by Gas Phase Atomic Clusters. AB - The increasing supply of natural gas has created a strong demand for developing efficient catalytic processes to upgrade methane, the most stable alkane molecule, into value-added chemicals. Currently, methane conversion in laboratory and industry is mostly performed under high-temperature conditions. A lot of effort has been devoted to exploring chemical entities that are able to activate the C-H bond of methane at lower temperatures, preferably room temperature. Gas phase atomic clusters with limited numbers of atoms are ideal models of active sites on heterogeneous catalysts. The cluster systems are being actively studied to activate methane under room-temperature conditions. State-of-the-art mass spectrometry, photoelectron imaging spectroscopy, and quantum chemistry calculations have been combined in our laboratory to reveal the molecular-level mechanisms of methane activation by atomic clusters. In this Account, we summarize our recent progress on thermal methane activation by metal oxide clusters doped with noble-metal atoms (Au, Pt, and Rh) as well as by oxygen-free species including carbides and borides of base metals (V, Ta, Mo, and Fe). In contrast to the generations of CH3* free radicals in many of the previously reported cluster reactions with methane, the generations of stable products such as formaldehyde, acetylene, and syngas as well as closed-shell species AuCH3 and B3CH3 have been identified for the cluster reaction systems herein. Besides the well recognized mechanisms of methane activation by the O-* radicals through hydrogen atom abstraction and by metal atoms through oxidative addition, the new mechanisms of synergistic methane activation by Lewis acid-base pairs (such as Audelta+-Odelta- and Bdelta+-Bdelta-) and by dinuclear metal centers (such as Ta Ta) have been recently revealed. In the reactions between methane and oxide clusters doped with noble-metal atoms, the oxide cluster "supports" can accept the H atoms and the CH x species delivered through the noble-metal atoms and then transform methane into stable oxygenated compounds. The product selectivity (such as formaldehyde versus syngas) can be controlled by different noble-metal atoms (such as Pt versus Rh). The electronic structures of base metal centers can be engineered through carburization so that the low-spin states can be accessible to reduce the C-H bond of methane. Such active base metal centers in low-spin states resemble related noble-metal atoms in methane activation. The boron clusters (such as B3 in VB3+) can be polarized by the metal cations to form the Lewis acid base pair Bdelta+-Bdelta- to cleave the C-H bond of methane very easily. These molecular-level mechanisms may well be operative in related heterogeneous catalysis and can be a fundamental basis to design efficient catalysts for activation and conversion of methane under mild conditions. PMID- 30289248 TI - Photoelectrochemical Approach to Apoptosis Evaluation via Multi-Functional Peptide- and Electrostatic Attraction-Guided Excitonic Response. AB - The excitonic response between nanomaterials is distance-dependent, and thus, interparticle distance is a key factor in fabricating diverse photoelectrochemical (PEC) systems. Current studies focus on DNA-mediated regulation of interparticle distance. However, limited by high demands of base pairing and flexibility of DNA, it is hard for DNA to achieve precise regulation, especially in a short distance. To pursue better PEC performances in bioanalyses, alternative biological materials should be explored to replace DNA as new "distance controllers". In this work, a peptide with three functional sequences is designed to control interparticle distance between positive-charged Au nanoparticles ((+) AuNPs) and negative-charged CdTe quantum dots ((-) CdTe QDs). Relying on the function of binding sequence, (+) AuNPs and (-) CdTe QDs may be separated to a certain distance by the multifunctional peptide. In this case, the excitonic response is relatively weak, and an evident PEC response can be observed. Because it contains the substrate sequence of caspase-3, the peptide is cleaved in the presence of caspase-3. As a result, without the support of intact peptide, electrostatic attraction plays a dominant role, leading to the aggregation of oppositely charged AuNPs and CdTe QDs, which strengthens the excitonic response and attenuates the PEC response. On the basis of these principles, a novel PEC approach was fabricated to sensitively quantify caspase 3. Meanwhile, caspase-3 in staurosporine-treated A549 cells are also determined by the approach, and the obtained results agree well with the fluorescent intensity of confocal images, manifesting that the proposed PEC method can monitor apoptosis in a label-free strategy. Overall, the study reveals the capability of peptides in controlling interparticle distance of nanomaterials, which may accelerate the development of peptide-based PEC analytical methods. PMID- 30289249 TI - Machine Learning Algorithms for Liquid Crystal-Based Sensors. AB - We present a machine learning (ML) framework to optimize the specificity and speed of liquid crystal (LC)-based chemical sensors. Specifically, we demonstrate that ML techniques can uncover valuable feature information from surface-driven LC orientational transitions triggered by the presence of different gas-phase analytes (and the corresponding optical responses) and can exploit such feature information to train accurate and automatic classifiers. We demonstrate the utility of the framework by designing an experimental LC system that exhibits similar optical responses to a stream of nitrogen containing either 10 ppmv dimethyl-methylphosphonate (DMMP) or 30% relative humidity (RH). The ML framework is used to process and classify thousands of images (optical micrographs) collected during the LC responses and we show that classification (sensing) accuracies of over 99% can be achieved. For the same experimental system, we demonstrate that traditional feature information used in characterizing LC responses (such as average brightness) can only achieve sensing accuracies of 60%. We also find that high accuracies can be achieved by using time snapshots collected early in the LC response, thus providing the ability to create fast sensors. We also show that the ML framework can be used to systematically analyze the quality of information embedded in LC responses and to filter out noise that arises from imperfect LC designs and from sample variations. We evaluate a range of classifiers and feature extraction methods and conclude that linear support vector machines are preferred and that high accuracies can only be achieved by simultaneously exploiting multiple sources of feature information.

AB - Molecular dynamics (MD) simulations allow for accurate prediction of the thermodynamic profile of binding-site water molecules critical for protein-ligand association. Whereas this hydration-site profiling converges rapidly for solvent exposed sites independent of the initial water placement, an accurate and reliable placement is required for water molecules in occluded binding sites. Here, we present an accurate and efficient hydration-site prediction method for occluded binding sites combining water placement based on 3D-RISM and MD simulations using WATsite. PMID- 30289251 TI - Half-Sandwich Iridium and Ruthenium Complexes: Effective Tracking in Cells and Anticancer Studies. AB - Half-sandwich metal-based anticancer complexes suffer from uncertain targets and mechanisms of action. Herein we report the observation of the images of half sandwich iridium and ruthenium complexes in cells detected by confocal microscopy. The confocal microscopy images showed that the cyclopentadienyl iridium complex 1 mainly accumulated in nuclei in A549 lung cancer cells, whereas the arene ruthenium complex 3 is located in mitochondria and lysosomes, mostly in mitochondria, although both complexes entered A549 cells mainly through energy dependent active transport. The nuclear morphological changes caused by Ir complex 1 were also detected by confocal microscopy. Ir complex 1 is more potent than cisplatin toward A549 and HeLa cells. DNA binding studies involved interaction with the nucleobases 9-ethylguanine, 9-methyladenine, ctDNA, and plasmid DNA. The determination of bovine serum albumin binding was also performed. Hydrolysis, stability, nucleobase binding, and catalytic NAD+/NADH hydride transfer tests for complexes 1 and 3 were also carried out. Both complexes activated depolarization of mitochondrial membrane potential and intracellular ROS overproduction and induced cell apoptosis. Complex 3 arrested the cell cycle at the G0/G1 phase by inactivation of CDK 4/cyclin D1. This work paves the way to track and monitor half-sandwich metal complexes in cells, shines a light on understanding their mechanism of action, and indicates their potential application as theranostic agents. PMID- 30289254 TI - Sensoproteomics: A New Approach for the Identification of Taste-Active Peptides in Fermented Foods. AB - Aiming at the identification of the key bitter peptides in fermented foods, a new approach, coined "sensoproteomics", was developed and applied to fresh cheese samples differing in bitter taste intensity. By means of MPLC fractionation of the water-soluble cheese extracts in combination with taste dilution analysis, complex fractions with intense bitter taste were located and then screened by UPLC-MS/MS for the entire repertoire of ~1600 candidate peptides, extracted from a literature meta-analysis on dairy products, by using a total of 120 selected reaction monitoring methods computed in silico. A total of 340 out of the 1600 peptides were found in the cheese samples, among which 17 peptides were identified as candidate bitter peptides by considering only peptides that were located in the bitter-tasting MPLC fractions (signal-to-noise ratio: >=10) with a fold-change of >=3 when comparing the less bitter to the more bitter cheese sample and that were validated by comparison with the synthetic reference peptides. While EIVPNS[phos]VEQK (alphas1-CN70-78) and INTIASGEPT (kappa-CN122 131) did not exhibit any bitter taste up to 2000 MUmol/L, 15 of the 17 target peptides showed bitter taste thresholds ranging from 30 (ARHPHPHLSFM, kappa-CN96 106) to 690 MUmol/L (IQKEDVPS, alphas1-CN81-88). Finally, quantitative peptide analysis followed by calculation of dose-overthreshold factors revealed a primary contribution of MAPKHKEMPFPKYPVEPF (beta-CN102-119) and ARHPHPHLSFM (kappa-CN96 106) to the perceived bitter taste of the fresh cheese samples. Finally, the evolution of the bitter peptides throughout two different fresh cheese manufacturing processes was quantitatively recorded. PMID- 30289253 TI - Unexplored Nucleotide Binding Modes for the ABC Exporter MsbA. AB - The ATP-binding cassette (ABC) transporter MsbA is an ATP-driven lipid-A flippase. It belongs to the ABC protein superfamily whose members are characterized by conserved motifs in their nucleotide binding domains (NBDs), which are responsible for ATP hydrolysis. Recently, it was found that MsbA could catalyze a reverse adenylate kinase (rAK)-like reaction in addition to ATP hydrolysis. Both reactions are connected and mediated by the same conserved NBD domains. Here, the structural foundations underlying the nucleotide binding to MsbA were therefore explored using a concerted approach based on conventional- and DNP-enhanced solid-state NMR, pulsed-EPR, and MD simulations. MsbA reconstituted into lipid bilayers was trapped in various catalytic states corresponding to intermediates of the coupled ATPase-rAK mechanism. The analysis of nucleotide-binding dependent chemical shift changes, and the detection of through-space contacts between bound nucleotides and MsbA within these states provides evidence for an additional nucleotide-binding site in close proximity to the Q-loop and the His-Switch. By replacing Mg2+ with Mn2+ and employing pulsed EPR spectroscopy, evidence is provided that this newly found nucleotide binding site does not interfere with the coordination of the required metal ion. Molecular dynamic (MD) simulations of nucleotide and metal binding required for the coupled ATPase-rAK mechanism have been used to corroborate these experimental findings and provide additional insight into nucleotide location, orientation, and possible binding modes. PMID- 30289255 TI - Interactions between the Molecular Components of the Cowpea Chlorotic Mottle Virus Investigated by Molecular Dynamics Simulations. AB - The formation of a viral particle generally involves hundreds of proteins, making the assembly process intricate. Despite its intrinsic complexity, the production of a viral particle begins through the interaction between the basic assembly components. For the cowpea chlorotic mottle virus (CCMV), the first steps of the assembly process involve dimers of the capsid protein. Here, we carried out atomistic molecular dynamics simulations to investigate the initial assembly process of CCMV to get insight into the interactions at the molecular level. We found that salinity not only affects the electrostatic interactions between dimers but also changes the conformation of the positively charged N-terminal tails and can cause a serious steric hindrance for other dimers binding to the hydrophobic domains. An RNA rod was used to mimic a long segment of a viral genome and to study its interaction with dimers. We observed that the dimer with tails prefers to bind on the RNA rod with its positively charged inner side. The dimer-RNA interaction was found to be as strong as the dimer-dimer interaction, whereas the association energies between a dimer and a pentamer or a hexamer of dimers were high but strongly depended on the presence of the tails. Upon heating, the capsid experienced a shrinkage accompanied by a loss of order in the icosahedral crystal structure. PMID- 30289256 TI - Quantitative Evaluation of Optical Free Carrier Generation in Semiconducting Single-Walled Carbon Nanotubes. AB - Gauging free carrier generation (FCG) in optically excited, charge-neutral single walled carbon nanotubes (SWNTs) has important implications for SWNT-based optoelectronics that rely upon conversion of photons to electrical current. Earlier investigations have largely provided only qualitative insights into optically triggered SWNT FCG, due to the heterogeneous nature of commonly interrogated SWNT samples and the lack of direct, unambiguous spectroscopic signatures that could be used to quantify charges. Here, employing ultrafast pump probe spectroscopy in conjunction with chirality-enriched, length-sorted, ionic polymer-wrapped SWNTs, we develop a straightforward approach for quantitatively evaluating the extent of optically driven FCG in SWNTs. Owing to the previously identified trion transient absorptive hallmark (Tr+11 -> Tr+nm) and the rapid nature of trion formation dynamics (<1 ps) relative to established free-carrier decay time scales (>ns), we correlate FCG with trion formation dynamics. Experimental determination of the trion absorptive cross section further enables evaluation of the quantum yields for optically driven FCG [Phi(E nn->h ++e -)] as a function of optical excitation energy and medium dielectric strength. We show that (i) E33 excitons give rise to dramatically enhanced Phi(E nn->h ++e -) relative to those derived from E22 and E11 excitons and (ii) Phi(E33->h ++e -) monotonically increases from ~5% to 18% as the solvent dielectric constant increases from ~32 to 80. This work highlights the extent to which the nature of the medium and excitation conditions control FCG quantum yields in SWNTs: such studies have the potential to provide new design insights for SWNT-based compositions for optoelectronic applications that include photodetectors and photovoltaics.

AB - The biological functions of the dual bromodomains of human transcription initiation-factor TFIID subunit 1 (TAF1(1,2)) remain unknown, although TAF1 has been identified as a potential target for oncology research. Here, we describe the discovery of a potent and selective in vitro tool compound for TAF1(2), starting from a previously reported lead. A cocrystal structure of lead compound 2 bound to TAF1(2) enabled structure-based design and structure-activity relationship studies that ultimately led to our in vitro tool compound, 27 (GNE 371). Compound 27 binds TAF1(2) with an IC50 of 10 nM while maintaining excellent selectivity over other bromodomain-family members. Compound 27 is also active in a cellular-TAF1(2) target-engagement assay (IC50 = 38 nM) and exhibits antiproliferative synergy with the BET inhibitor JQ1, suggesting engagement of endogenous TAF1 by 27 and further supporting the use of 27 in mechanistic and target-validation studies.

AB - The possible formation of the (AlF4(HF) n)- ( n = 1-8 and 12), (AsF6(HF) n)-, and (SbF6(HF) n)- ( n = 1-6 and 12) anionic clusters of a superhalogen nature is predicted in the solutions of binary HF/AlF3, HF/AsF5, and HF/SbF5 Lewis-Bronsted superacids on the basis of ab initio calculations. Our results show that all systems investigated represent extremely strongly bound anions characterized by vertical electron detachment energies (VDEs) that significantly exceed 10 eV. The VDE values estimated for the (AlF4(HF)12)-, (AsF6(HF)12)-, and (SbF6(HF)12)- systems are predicted to be 13.96, 14.03, and 14.03 eV, respectively, and are the largest vertical electron detachment energies reported in the literature thus far. PMID- 30289259 TI - Asymmetric Boron-Cored Aggregation-Induced Emission Luminogen with Multiple Functions Synthesized through Stepwise Conversion from a Symmetric Ligand. AB - Multifunction luminogens have emerged as promising candidates in high-performance sensor and imaging systems. Concise approaches to the synthesis of such molecules are urgently required both for fundamental research and technological applications. In this study, a new symmetric ligand of di(2 hydroxyphenyl)phthalazine with multiple binding sites around a phthalazine unit was readily synthesized, which could be converted efficiently into an asymmetric luminogen (OBN-DHPP) through the formation of oxygen-boron-nitrogen bonding. This molecule has a twistable pi-extended backbone with a tetracoordinated boron core bearing two bulky phenyl groups, giving it abundant optical properties including a large Stokes shift piezochromism and aggregation-induced emission enhancement. Importantly, the presence of a free phenolic hydroxyl group in the backbone of OBN-DHPP enables the incorporation of various functional moieties into the asymmetric luminogen. As an example, polyethylene glycol (PEG)-modified luminogen (OBN-DHPP-PEG45) was synthesized. In the aqueous medium, OBN-DHPP-PEG45 could self-assemble into spherical nanoparticles with low cytotoxicity and excellent emission performance as well as high solubility. The results of flow cytometry and fluorescence microscopy reveal that these nanoparticles could be internalized successfully by HeLa cells, demonstrating their potential application in bioimaging.

AB - This study is the first large-scale survey of the presence of dihydroxyacetone (DHA) in the nectar of the Australian Leptospermum tree species. The work undertaken supports the growing global demand for bioactive Leptospermum honey. Leptospermum honey derived from L. scoparium in New Zealand, also referred to as Manuka honey, has a reputation for wound-healing and antimicrobial properties, which is based on its methylglyoxal (MGO) content. High-DHA nectar correlates to high-MGO honey, but not all Leptospermum species produce DHA in their nectar. This study investigates 55 of the 84 Leptospermum species native to Australia for their DHA-producing capability, with the DHA to total sugar (DHA:Tsugar) ratio of nectar samples determined by HPLC-PDA. DHA:Tsugar ranged from nondetectable in L. laevigatum, L. coriaceum, and L. trinervium to >16 000 mg/kg in L. speciosum and L. whitei. High-DHA Leptospermum species were identified for beekeepers to target for honey production and plantation development. PMID- 30289261 TI - Cell Volume Controls Protein Stability and Compactness of the Unfolded State. AB - Macromolecular crowding is widely accepted as one of the factors that can alter protein stability, structure, and function inside cells. Less often considered is that crowding can be dynamic: as cell volume changes, either as a result of external duress or in the course of the cell cycle, water moves in or out through membrane channels, and crowding changes in tune. Both theory and in vitro experiments predict that protein stability will be altered as a result of crowding changes. However, it is unclear how much the structural ensemble is altered as crowding changes in the cell. To test this, we look at the response of a FRET-labeled kinase to osmotically induced volume changes in live cells. We examine both the folded and unfolded states of the kinase by changing the temperature of the media surrounding the cell. Our data reveals that crowding compacts the structure of its unfolded ensemble but stabilizes the folded protein. We propose that the structure of proteins lacking a rigid, well-defined tertiary structure could be highly sensitive to both increases and decreases in cell volume. Our findings present a possible mechanism for disordered proteins to act as sensors and actuators of cell cycle or external stress events that coincide with a change in macromolecular crowding.

Control experiments and DFT calculations indicate that the CF3SO2Na/K2S2O8 system is capable of trifluoromethylating the substrate of alkenes without a transition metal catalyst and the oxidation of CF3SO2Na to .CF3 by K2S2O8 is involved in the rate-determining step. PMID- 30289262 TI - Amino Acid Stabilization of Nucleic Acid Secondary Structure: Kinetic Insights from Single-Molecule Studies. AB - Amino acid and nucleic acid interactions are central in biology and may have played a role in the evolutionary development of protein-based life from an early "RNA Universe." To explore the possible role of single amino acids in promoting nucleic acid folding, single-molecule Forster resonance energy transfer experiments have been implemented with a DNA hairpin construct (7 nucleotide double strand with a 40A loop) as a simple model for secondary structure formation. Exposure to positively charged amino acids (arginine and lysine) is found to clearly stabilize the secondary structure. Kinetically, each amino acid promotes folding by generating a large increase in the folding rate with little change in the unfolding rate. From analysis as a function of temperature, arginine and lysine are found to significantly increase the overall exothermicity of folding while imposing only a small entropic penalty on the folding process. Detailed investigations into the kinetics and thermodynamics of this amino acid induced folding stability reveal arginine and lysine to interact with nucleic acids in a manner reminiscent of monovalent cations. Specifically, these observations are interpreted in the context of an ion atmosphere surrounding the nucleic acid, in which amino acid salts stabilize folding qualitatively like small monovalent cations but also exhibit differences because of the composition of their side chains. PMID- 30289264 TI - Energy-Resolved Photoconductivity Mapping in a Monolayer-Bilayer WSe2 Lateral Heterostructure. AB - Vertical and lateral heterostructures of van der Waals materials provide tremendous flexibility for band-structure engineering. Because electronic bands are sensitively affected by defects, strain, and interlayer coupling, the edge and heterojunction of these two-dimensional (2D) systems may exhibit novel physical properties, which can be fully revealed only by spatially resolved probes. Here, we report the spatial mapping of photoconductivity in a monolayer bilayer WSe2 lateral heterostructure under multiple excitation lasers. As the photon energy increases, the light-induced conductivity detected by microwave impedance microscopy first appears along the heterointerface and bilayer edge, then along the monolayer edge, inside the bilayer area, and finally in the interior of the monolayer region. The sequential emergence of mobile carriers in different sections of the sample is consistent with the theoretical calculation of local energy gaps. Quantitative analysis of the microscopy and transport data also reveals the linear dependence of photoconductivity on the laser intensity and the influence of interlayer coupling on carrier recombination. Combining theoretical modeling, atomic-scale imaging, mesoscale impedance microscopy, and device-level characterization, our work suggests an exciting perspective for controlling the intrinsic band gap variation in 2D heterostructures down to a regime of a few nanometers.

AB - A novel multicomponent reaction of p-(trifluoromethyl)- p-quinolsilyl ethers, ketones, and nitriles was developed for the efficient synthesis of p trifluoromethylated N-benzylamides. The key step of the reaction involves the formation of an unstable condensation precursor in situ generated form the condensation of p-(trifluoromethyl)- p-quinolsilyl ethers with ketones. This work provides a significant expansion to the Ritter-type reaction, and the reaction can proceed under mild reaction conditions and tolerate various nitriles including both aryl and aliphatic nitriles. PMID- 30289267 TI - Eosinophilic Angiocentric Fibrosis: A Review and Update of Its Association With Immunoglobulin G4-Related Disease. AB - Eosinophilic angiocentric fibrosis is a rare indolent lesion of the head and neck region that has characteristic histologic findings of onionskin fibrosis and prominent eosinophils. Its pathogenesis has been poorly understood and has been most commonly attributed to hypersensitivity or previous trauma. Recently, the lesion has been included in the spectrum of immunoglobulin G4 (IgG4)-related disease. However, few of the existing cases of eosinophilic angiocentric fibrosis have been evaluated for IgG4+ and IgG+ plasma cells. Therefore, we provide an update on the clinical and histologic features of eosinophilic angiocentric fibrosis to increase awareness of the entity and encourage its further characterization as an IgG4-related disease. PMID- 30289268 TI - Comparing Spore Resistance of Bacillus Strains Isolated from Hydrothermal Vents and Spacecraft Assembly Facilities to Environmental Stressors and Decontamination Treatments. AB - Submarine hydrothermal vents are inhabited by a variety of microorganisms capable of tolerating environmental extremes, making them ideal candidates to further expand our knowledge of the limitations for terrestrial life, including their ability to survive the exposure of spaceflight-relevant conditions. The spore resistance of two Bacillus spp. strains, APA and SBP3, isolated from two shallow vents off Panarea Island (Aeolian Islands, Italy), to artificial and environmental stressors (i.e., UVC radiation, X-rays, heat, space vacuum, hydrogen peroxide [H2O2], and low-pressure plasma), was compared with that of two close phylogenetic relatives (Bacillus horneckiae and Bacillus oceanisediminis). Additional comparisons were made with Bacillus sp. isolated from spacecraft assembly facilities (B. horneckiae, Bacillus pumilus SAFR-032, and Bacillus nealsonii) and the biodosimetry strain and space microbiology model organism Bacillus subtilis. Overall, a high degree of spore resistance to stressors was observed for the strains isolated from spacecraft assembly facilities, with an exceptional level of resistance seen by B. pumilus SAFR-032. The environmental isolate SBP3 showed a more robust spore resistance to UVC, X-rays, H2O2, dry heat, and space vacuum than the closely related B. horneckiae. Both strains (SBP3 and APA) were more thermotolerant than their relatives, B. horneckiae and B. oceanisediminis, respectively. SBP3 may have a novel use as a bacterial model organism for future interrogations into the potential of forward contamination in extraterrestrial environments (e.g., icy moons of Jupiter or Saturn), spacecraft sterilization and, broadly, microbial responses to spaceflight-relevant environmental stressors.

Although SDH subunits and assembly factors form part of the same enzyme complex, mutations in their respective genes lead to significantly different clinical phenotypes. Remarkable discoveries in the last 17 years have led to the delineation of the SDH complex deficiency syndrome and its multiple pathogenic branches. Here we provide an updated overview of SDH deficiency in order to raise awareness of its multiple connotations including nonneoplastic associations and pertinent features of the continually growing list of SDH-mutant tumors so as to better direct genetic counseling and predict prognosis.

AB - Goat milk powder is a nutritious and easy-to-store product that is highly favored by consumers. However, the presence of contaminating bacteria and their metabolites may significantly affect the flavor, solubility, shelf life, and safety of the product. To comprehensively and accurately understand the sanitary conditions in the goat milk powder production process and potential threats from bacterial contamination, a combination of Pacific Biosciences single molecule real-time sequencing and droplet digital PCR was used to evaluate bacterial contamination in seven goat milk powder samples from three dairies. Ten phyla, 119 genera, and 249 bacterial species were identified. Bacillus, Paenibacillus, Lactococcus, and Cronobacter were the primary genera. Bacillus cereus, Lactococcus lactis, Alkaliphilus oremlandii, and Cronobacter sakazakii were the dominant species. With droplet digital PCR, 6.3 * 104 copies per g of Bacillus cereus and 1.0 * 104 copies per g of Cronobacter spp. were quantified, which may increase the risk of food spoilage and the probability of foodborne illness and should be monitored and controlled. This study offers a new approach for evaluating bacterial contamination in goat milk powder and supplies a reference for the assessment of food safety and control of potential risk, which will be of interest to the dairy industry. PMID- 30289271 TI - Sedentary time, metabolic abnormalities, and all-cause mortality after myocardial infarction: A mediation analysis. AB - Background Sedentary time was associated with myocardial infarction (MI) and metabolic diseases in previous studies. Purpose To investigate whether sedentary time measured before disease onset was associated with all-cause mortality among MI survivors and whether the sedentary time-mortality association was mediated by physical activity status and metabolic phenotypes. Methods In this prospective community-based cohort including 101,510 Chinese adults, we used sedentary time, evaluated at 2006 (baseline), to predict further all-cause mortality among individuals who then developed new onset MI from 2006 to December 2013 ( n = 989). The post-MI mortality was ascertained after the first non-fatal MI until December 2014. We assessed the mediating effects of physical inactivity and metabolic factors on the sedentary time-mortality association. Results During 7 years follow up, 180 deaths occurred among these participants with incident MI. Prolonged sedentary time was associated with a higher risk of mortality among MI survivors. The adjusted hazard ratio (HR) of mortality for sedentary time 4-8 hours/day versus <4 hours/day, was 1.62 (95% confidence interval (CI) 1.14-2.31). A high amount of sedentary time (>4 hours/day) and inactive physical activity had an increased risk of all-cause mortality (HR: 2.74, 95% CI 1.34-5.60), relative to those with sedentary time <=4 hours/day and moderate/vigorous physical activity. Physical inactivity and metabolic factors mediated a small proportion (<=9.2 % for all) of the total association between sedentary time and post-MI mortality. Conclusion High sedentary time was significantly associated with all cause mortality among MI survivors, independent of physical activity status and metabolic abnormalities.

PMID- 30289273 TI - Effectiveness of different outreach strategies to identify individuals at high risk of diabetes in a heterogeneous population: a study in the Swedish municipality of Sodertalje. AB - BACKGROUND: Identifying type 2 diabetes mellitus (T2DM) is a prerequisite for the institution of preventive measures to reduce future micro and macrovascular complications. Approximately 50% of people with T2DM are undiagnosed, challenging the assumption that a traditional primary healthcare setting is the most efficient way to reach people at risk of T2DM. A setting of this kind may be even more suboptimal when it comes to reaching immigrants, who often appear to have inferior access to healthcare and/or are less likely to attend routine health checks at primary healthcare centres. OBJECTIVES: The objective of this study was to identify the best strategy to reach individuals at high risk of T2DM and thereby cardiovascular disease in a heterogeneous population. METHODS: All 18-65 year-old inhabitants in the Swedish municipality of Sodertalje ( n~51,000) without known T2DM and cardiovascular disease were encouraged to complete the Finnish Diabetes Risk Score (FINDRISC: score > 15 indicating a high and > 20 a very high risk of future T2DM and cardiovascular disease) through the following communication channels: primary care centres, workplaces, Syrian orthodox churches, pharmacies, crowded public places, mass media, social media and mail. Data collection lasted for six weeks. RESULTS: The highest response rate was obtained through workplaces (27%) and the largest proportion of respondents at high/very high risk through the Syrian orthodox churches (18%). The proportion reached through primary care centres was 4%, of whom 5% were at elevated risk. The cost of identifying a person at elevated risk through the Syrian orthodox church was ?104 compared with ?8 through workplaces and ?112 through primary care centres. CONCLUSIONS: The choice of communication channels was important to reach high/very high-risk individuals for T2DM and for screening costs. In this immigrant-dense community, primary care centres were inferior to strategies using workplaces and churches in terms of both the proportion of identified at-risk individuals and costs.

AB - The Tanpopo mission has two objectives: (1) test the panspermia hypothesis and (2) test whether organic compounds may have been transferred to Earth before the origin of life. We developed an exposure panel (EP) designed to expose microbes and organic compounds to the space environment and a capture panel designed to capture high-velocity particles on the International Space Station (ISS) using aerogel contained in an aluminum container. The panels returned after 1 year of exposure at the Exposure Facility of the Japan Experimental Module, ISS. In this communication, we report the measurements of temperature, radiation dosimeter and vacuum ultraviolet dosimeter in the EP, and survival data of Deinococcus aetherius. The environmental data are consistent with survival data of microbes and organic compounds, which will be presented elsewhere in detail. PMID- 30289275 TI - Return to Play and In-Game Performance Statistics Among Pitchers After Ulnar Collateral Ligament Reconstruction of the Elbow: A Systematic Review. AB - BACKGROUND: Injury to the ulnar collateral ligament of the elbow is relatively common among baseball pitchers. Ulnar collateral ligament reconstruction (UCLR) has revolutionized the management of this injury, allowing a greater proportion of pitchers to return to play. PURPOSE: To assess the return to play and in-game performance specific to baseball pitchers who have undergone primary UCLR. STUDY DESIGN: Systematic review. METHODS: This review was conducted according to the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta Analyses). The electronic databases MEDLINE, EMBASE, and PubMed were searched for relevant studies, and pertinent data were abstracted. Only studies reporting in game performance statistics (earned run average [ERA], pitching velocity, innings pitched per season, etc) of pitchers after UCLR were included. The methodological index for nonrandomized studies (MINORS) was used to assess study quality. RESULTS: A total of 14 studies and 1520 pitchers were included in this systematic review. All studies were of level 3 or 4 evidence, and the mean +/- SD MINORS score was 14.4 +/- 3.0, which indicates fair quality of evidence for nonrandomized studies. The rates of return to any level of pitching after UCLR ranged from 79% to 100%. Subgroup analysis revealed that 79% to 87% of Major League Baseball (MLB) pitchers returned to preinjury levels of pitching. The mean time to return to play was 19.8 +/- 13.5 months, and the mean time to return to competition for MLB pitchers was 17.3 +/- 2.4 months. Of the 5 studies reporting ERA, 2 cited a significant increase after UCLR, and 1 indicated a significant decrease. Of the 4 studies reporting fastball velocity, 3 cited decreased pitching velocities after UCLR. All studies found that pitchers pitched, on average, fewer innings per game or season after UCLR. CONCLUSION: There was a high rate of return to pitching after UCLR. However, most studies showed that UCLR was associated with a prolonged recovery and significant decline in pitching performance as objectively measured by in-game statistics. The strength of these conclusions is limited by the quality of the available literature and inconsistencies in the reporting of outcomes. PMID- 30289277 TI - Assessment of radiation dose from radon ingestion and inhalation in commercially bottled drinking water and its annual effective dose in Eastern Province, Saudi Arabia. AB - The isotopes of radium, uranium, polonium, lead, and short-lived radon are the common radionuclides found in drinking water. The abnormal amount of radon in drinking water causes health risks. In this study, an attempt has been made to estimate the level of radon concentrations and its annual effective dose from bottled water brands and tap drinking water. A total of 77 samples of drinking water sources; 47 bottled water brands and 27 tap water samples including 3 samples from water storage tank supplier were collected and examined. The measurements were performed using active detection method technique called Durridge RAD7-H2O with closed loop. The minimum and maximum level of average radon concentrations was 0.10 +/- 0.02 BqL-1 and 9.2 +/- 0.02 BqL-1. The results were below the limit recommended by the Environmental Protection Agency (11 BqL 1). The annual effective dose for children and adults was in the range from almost 0.51 uSvy-1 to 46.69 uSvy-1. There are no indications of significant threat from radon concentrations in bottled water brands or tap drinking water, and it is safe as far as health hazard is concerned. PMID- 30289279 TI - Paleolakes of Northeast Hellas: Precipitation, Groundwater-Fed, and Fluvial Lakes in the Navua-Hadriacus-Ausonia Region, Mars. AB - The slopes of northeastern Hellas Basin, Mars exhibit a wide variety of fluvial landforms. In addition to the Dao-Niger-Harmakhis-Reull Valles outflow channels, many smaller channels and valleys cut into this terrain, several of which include discontinuous sections. We have mapped these channels and channel-associated depressions to investigate potential paleolakes from the Navua Valles in the West, through the Hadriacus Mons volcano in the center, to the Ausonia Montes in the East. We have identified three groups of candidate paleolakes at the source regions of major drainages and a fourth paleolake type scattered along the lower reaches of these drainages. Each paleolake group has a distinct character, determined by different formative processes, including precipitation and groundwater for lakes at the channel sources, and fluvially transported water at the lower channel reaches. Only one of these 34 basins had been cataloged previously in paleolake basin databases. Several of these sites are at proximity to the Hadriacus volcanic center, where active dikes during the Hesperian could have produced hydrothermal systems and habitable environments. Deposits within these paleolake depressions and at the termini of channels connected to these candidate paleolakes contain the geological and potentially biological record of these environments. PMID- 30289278 TI - Altered Functional Connectivity of the Executive Functions Network During a Stroop Task in Children with Reading Difficulties. AB - Children with reading difficulties (RDs) often receive related accommodations in schools, such as additional time for examinations and reading aloud written material. Existing data suggest that these readers share challenges in executive functions (EFs). Our study was designed to determine whether children with RDs have specific challenges in EFs and define neurobiological signatures for such difficulties using magnetic resonance imaging (MRI) data. Reading and EFs abilities were assessed in 8-12-year-old children with RDs and age-matched typical readers. Functional MRI data were acquired during a Stroop task, and functional connectivity of the EFs defined network was calculated in both groups and related to reading ability. Children with RDs showed lower reading and EFs abilities and demonstrated greater functional connectivity between the EFs network and visual, language, and cognitive control regions during the Stroop task, compared to typical readers. Our results suggest that children with RDs utilize neural circuits supporting EFs more so than do typical readers to perform a cognitive task. These results also provide a neurobiological explanation for the challenges in EFs shared by children with RDs and explain challenges this group shares outside of the reading domain. PMID- 30289280 TI - Altered Functional Connectivity Observed at Rest in Children and Adolescents Prenatally Exposed to Alcohol. AB - Studies of brain structure in fetal alcohol spectrum disorder (FASD) have shown the global and focal effects that prenatal alcohol exposure (PAE) has on the brain, suggesting but not measuring altered function in FASD. This study aimed to (1) identify resting-state functional networks in children and adolescents with FASD, (2) investigate functional connectivity differences compared with healthy controls, and (3) assess the links to cognitive deficits. Participants included 66 children/adolescents with FASD (aged 5.5-18.9 years) and 67 healthy controls (aged 5.8-18.5 years) scanned across four sites as part of the NeuroDevNet study. Six core functional networks with 27 regions of interest (ROIs) were examined using seed-based and ROI-to-ROI analyses. Average seed-based connectivity maps showed significant spatial overlap of positively correlated regions for all six core networks between FASD and controls, but there was less overlap for negatively correlated regions. ROI-to-ROI matrices demonstrated lower internetwork connectivity between regions primarily associated with the salience network (anterior cingulate cortex and bilateral insula), frontal-parietal network (bilateral posterior parietal cortex), and language network (right posterior superior temporal gyrus). Post hoc correlations of the FASD participants without medication revealed a relationship between functional connectivity and performance on two cognitive tests associated with mathematics ability and attention. Even though participants with PAE exhibit very similar intranetwork functional connectivity patterns as controls, their lower internetwork functional connectivity suggests underlying deficits in the functional network brain architecture that may be related to cognitive impairment. PMID- 30289281 TI - Evaluation of Common Variants in Matrix Metalloproteinase-9 Gene with Lumbar Disc Herniation in Han Chinese Population. AB - OBJECTIVE: Lumbar disc herniation (LDH) is a common and frequent orthopedic disease with strong genetic determinants. The disruption of the intervertebral disc extracellular matrix has been found to play a key role in the development of LDH, suggesting that abnormal matrix metalloproteinases (MMPs) may promote the degradation of the disc matrix. MMP-9, an important member of the MMP family, is a good candidate for the LDH susceptibility gene. The present study aimed to investigate the association of common variants in the MMP-9 gene with the risk, severity, and clinical characteristic variables of LDH. MATERIALS AND METHODS: Fourteen tag single nucleotide polymorphisms (SNPs) entirely covering the region of the MMP-9 gene were analyzed in a sample of 845 patients and 1751 healthy controls. RESULTS: The SNP rs17576 was found to be significantly associated with susceptibility to LDH (OR = 0.77, p = 0.0002), which was also confirmed by haplotype-based analyses (rs79845319-rs17576-rs45437897, global p < 0.001). Our results indicated that the A allele of rs17576 reduced the risk of LDH by ~23% on average. Furthermore, the G allele of rs17576 was found to correlate with more severe grades of disc degeneration. CONCLUSION: Our results provide additional evidence supporting an important role of the MMP-9 gene in the pathogenesis of LDH. PMID- 30289282 TI - Immunoregulatory effects of indole-3-carbinol on monocyte-derived macrophages in systemic lupus erythematosus: A crucial role for aryl hydrocarbon receptor. AB - Macrophages are versatile phagocytic cells in immune system with immunoregulatory functions. However, the removal of apoptotic cells by macrophages is disturbed in systemic lupus erythematosus (SLE). Aryl hydrocarbon receptor (AhR) is a ligand activated cytoplasmic receptor and transcription factor with diverse effects on immune response. Indole-3-carbinol (I3C) is an AhR agonist which has been implicated as a beneficial factor in regulating inflammation and cytokine expression in murine models of SLE. However, the molecular mechanisms are not thoroughly studied. Here, we aimed to investigate the ex vivo effects of I3C on polarization of monocyte-derived macrophages (MDMs) in SLE patients and the expression of regulatory cytokines upon AhR activation. MDMs from 15 newly diagnosed SLE patients and 10 normal subjects were induced by Jurkat apoptotic bodies (JABs) and treated with I3C. I3C enhanced the nuclear accumulation of AhR among MDMs of SLE patients and altered the expression of AhR target genes including CYP1A1, IL1- beta, IDO-1 and MRC-1. The imbalanced expression of pro- and anti- inflammatory cytokines (IL-10, IL-12, TGFbeta1, TNFalpha, IL-23, IL-6 and IFN-gamma) was compensated in response to I3C. AhR activation was also associated with the overexpression of M2 markers (CD163) and downregulation of M1 markers (CD86). Thus, macrophages are activated alternatively in response to I3C. The obtained data indicate that I3C-mediated AhR activation possess immunoregulatory effects on macrophages of SLE patients by exerting an obvious downregulation in the expression of pro-inflammatory and overexpression of anti inflammatory cytokines. Therefore, AhR could be targeted and further investigated as a choice of anti-inflammatory therapies for autoimmune disorders such as SLE. PMID- 30289283 TI - A Systematic Review of the Outcomes Used to Assess Upper Body Lymphedema. AB - PURPOSE: To ascertain how change in upper body lymphedema is assessed and understand how clinically significant change is determined. METHOD: A systematic search of the literature resulted in 55 eligible studies for analysis. RESULTS: A range of assessment methods, measurement protocols, and outcomes were used in the literature. Of the 21 studies in which thresholds for change were set a priori, 20 different thresholds were reported. CONCLUSION: How data was measured, analysed and reported was inconsistent across studies. Consensus on a core outcome set with standardised assessment protocols and reporting; and investigation into empirically based minimum important differences (MID) is needed. PMID- 30289284 TI - Effect of poly (l-lactic acid) scaffolds seeded with aligned diaphragmatic myoblasts overexpressing connexin-43 on infarct size and ventricular function in sheep with acute coronary occlusion. AB - Diaphragmatic myoblasts (DM) are stem cells of the diaphragm, a muscle displaying high resistance to stress and exhaustion. We hypothesized that DM modified to overexpress connexin-43 (cx43), seeded on aligned poly (l-lactic acid) (PLLA) sheets would decrease infarct size and improve ventricular function in sheep with acute myocardial infarction (AMI). Sheep with AMI received PLLA sheets without DM (PLLA group), sheets with DM (PLLA-DM group), sheets with DM overexpressing cx43 (PLLA-DMcx43) or no treatment (control group, n = 6 per group). Infarct size (cardiac magnetic resonance) decreased ~25% in PLLA-DMcx43 [from 8.2 +/- 0.6 ml (day 2) to 6.5 +/- 0.7 ml (day 45), p < .01, ANOVA-Bonferroni] but not in the other groups. Ejection fraction (EF%) (echocardiography) at 3 days post-AMI fell significantly in all groups. At 45 days, PLLA-DM y PLLA-DMcx43 recovered their EF% to pre-AMI values (PLLA-DM: 61.1 +/- 0.5% vs. 58.9 +/- 3.3%, p = NS; PLLA DMcx43: 64.6 +/- 2.9% vs. 56.9 +/- 2.4%, p = NS), but not in control (56.8 +/- 2.0% vs. 43.8 +/- 1.1%, p < .01) and PLLA (65.7 +/- 2.1% vs. 56.6 +/- 4.8%, p < .01). Capillary density was higher (p < .05) in PLLA-DMcx43 group than in the remaining groups. In conclusion, PLLA-DMcx43 reduces infarct size in sheep with AMI. PLLA-DMcx43 and PLLA-DM improve ventricular function similarly. Given its safety and feasibility, this novel approach may prove beneficial in the clinic. [Formula: see text]. PMID- 30289285 TI - Ubiquitin Associated and SH3 Domain Containing B (UBASH3B) Gene Association with Behcet's Disease in Iranian Population. AB - PURPOSE: To evaluate the possible association of UBASH3B gene rs4936742 (T > C) polymorphism with Behcet's disease (BD) and posterior uveitis in BD. MATERIALS AND METHODS: One hundred and thirty-one patients with BD (51 Behcet's posterior uveitis and 80 non-ocular Behcet's patients) and 61 unrelated age-matched healthy individuals as a control group without any inflammatory disease were selected. All BD cases were under follow-up and treatment in uveitis or rheumatology clinics for at least 5 years. All research subjects, including control individuals, received a comprehensive rheumatologic evaluation. All patients and controls were genotyped for UBASH3B rs4936742 (T > C) polymorphism by PCR-RFLP technique. RESULTS: The observed frequencies of genotypes were significantly different among patients and controls (19.7% versus 30.5% for TT, OR = 2.9, P = 0.011 and 36.1% versus 45.8% for CT, OR = 2.38, P = 0.017). Frequencies of T allele showed significantly higher values in Behcet's patients (OR = 1.9, P = 0.004). Subgroup genotypic and allelic analyses disclosed no significant difference between Behcet's posterior uveitis and control groups, neither between Behcet's posterior uveitis and non-ocular BD groups. However, genotypic and allelic analyses between non-ocular BD and control groups revealed statistically significant difference (36.3% versus 19.7% for TT, OR = 4.08, P = 0.003 and 43.8% versus 36.1% for CT, OR = 2.68, P = 0.018, 58.1% versus 37.7% for T allele, OR = 2.29, P = 0.001). Individuals carrying the TT genotype for UBASH3B were four times more likely to develop non-ocular BD than unaffected, control individuals. CONCLUSION: Our results showed that the UBASH3B gene rs4936742 (T > C) polymorphism is associated with an increased risk of Behcet's disease, especially non-ocular BD, in Iranian population. We could not find any susceptibility role of this genetic locus for posterior uveitis in Behcet's disease. PMID- 30289286 TI - Trust, Sexual Trust, and Sexual Health: An Interrogative Review. AB - Trust is experienced almost constantly in all forms of social and interpersonal relationships, including sexual relationships, and may contribute both directly and indirectly to sexual health. The purpose of this review is to link three aspects of trust to sexual health: (1) the role of trust in sexual relationships; (2) the role of trust in sexually transmitted infection (STI) prevention, particularly condom use; and (3) the relevance of trust in sexual relationships outside of the traditional model of monogamy. The review ends with consideration of perspectives that could guide new research toward understanding the enigmas of trust in partnered sexual relations in the context of sexual and public health. PMID- 30289287 TI - A randomized double-blind parallel-group phase III study to compare the efficacy and safety of NI-071 and infliximab reference product in Japanese patients with active rheumatoid arthritis refractory to methotrexate. AB - OBJECTIVES: This study aimed to demonstrate the equivalence of NI-071, an infliximab biosimilar (BS), and the infliximab reference product (RP) for treating Japanese patients with active rheumatoid arthritis (RA) refractory to methotrexate. METHODS: In this multicenter two-period phase III study, patients were treated with BS or RP for 30 weeks (Period I) in a randomized double-blind manner and then with BS for the following 24 weeks (Period II). The efficacy and safety of BS and RP were compared. RESULTS: The disease activity score in 28 joint count based on erythrocyte sedimentation rate or C-reactive protein and the American College of Rheumatology 20/50/70-based efficacy profiles of BS were similar to those of RP during Period I (30 weeks) including evaluations at Week 14, a critical time point. BS efficacy was maintained throughout the 54-week study period. BS efficacy profile matched the RP profile until Week 54 after the drug switch from RP to BS at Week 30. The safety profiles of BS and RP were comparable and the long-term safety of BS was confirmed. CONCLUSIONS: BS demonstrated equivalent efficacy and safety to RP at treatment weeks 14 and 30, and long-term safety until Week 54 in Japanese RA patients. PMID- 30289288 TI - CORRECTION.

PMID- 30289290 TI - Managing Acute Insomnia in Prison: Evaluation of a "One-Shot" Cognitive Behavioral Therapy for Insomnia (CBT-I) Intervention. AB - OBJECTIVES/BACKGROUND: Insomnia is a serious condition that affects over 60% of the prison population and has been associated with aggression, anger, impulsivity, suicidality, and increased prison health care use. Nonpharmacological interventions for prison inmates are scarce despite the high prevalence and significant consequences of insomnia among those incarcerated. The aim of the present study was to examine the preliminary efficacy and effectiveness of a one-shot session of cognitive behavioral therapy for insomnia (CBT-I) for prison inmates with acute insomnia in an open trial. Method/Participants: The intervention consisted of one 60-70 min session of CBT-I and a self-management pamphlet. A consecutive series of 30 adult male offenders with acute insomnia from a UK prison completed measures of prospective sleep (daily sleep diary), insomnia symptoms severity (Insomnia Severity Index), and mood symptoms (Patient Health Questionnaire and General Anxiety Disorder) one week before and four weeks after receiving the intervention. RESULTS: Pairwise t tests revealed that a single shot of CBT-I was effective in reducing the severity of insomnia in adult male offenders (t = [29], 12.65, p < 0.001). Further, the results demonstrated moderate to large effect sizes for reductions in depressive (dRM = 0.77) and anxious (dRM = 0.83) symptoms, as well as insomnia severity (dRM = 2.35). CONCLUSIONS: A single-shot session of CBT-I is effective in managing acute insomnia and mood (depression, anxiety) symptoms in adult male prison inmates. Future research should focus on testing if the single-shot CBT-I intervention can be implemented and disseminated in other settings and populations (e.g., female and juvenile or youth offenders). PMID- 30289291 TI - Adaptive radiotherapy for head and neck cancer. AB - INTRODUCTION: Large anatomical variations can be observed during the treatment course intensity-modulated radiotherapy (IMRT) for head and neck cancer (HNC), leading to potential dose variations. Adaptive radiotherapy (ART) uses one or several replanning sessions to correct these variations and thus optimize the delivered dose distribution to the daily anatomy of the patient. This review, which is focused on ART in the HNC, aims to identify the various strategies of ART and to estimate the dosimetric and clinical benefits of these strategies. MATERIAL AND METHODS: We performed an electronic search of articles published in PubMed/MEDLINE and Science Direct from January 2005 to December 2016. Among a total of 134 articles assessed for eligibility, 29 articles were ultimately retained for the review. Eighteen studies evaluated dosimetric variations without ART, and 11 studies reported the benefits of ART. RESULTS: Eight in silico studies tested a number of replanning sessions, ranging from 1 to 6, aiming primarily to reduce the dose to the parotid glands. The optimal timing for replanning appears to be early during the first two weeks of treatment. Compared to standard IMRT, ART decreases the mean dose to the parotid gland from 0.6 to 6 Gy and the maximum dose to the spinal cord from 0.1 to 4 Gy while improving target coverage and homogeneity in most studies. Only five studies reported the clinical results of ART, and three of those studies included a non-randomized comparison with standard IMRT. These studies suggest a benefit of ART in regard to decreasing xerostomia, increasing quality of life, and increasing local control. Patients with the largest early anatomical and dose variations are the best candidates for ART. CONCLUSION: ART may decrease toxicity and improve local control for locally advanced HNC. However, randomized trials are necessary to demonstrate the benefit of ART before using the technique in routine practice. PMID- 30289292 TI - Potential Pitfalls in Analyzing Structural Uncoupling of Endothelial NO Synthase: Aging is Not Associated with Increased Enzyme Monomerization. AB - Homodimer formation is essential for the normal activity of endothelial NO synthase (eNOS). Structural uncoupling of eNOS with generation of enzyme monomers is thought to contribute to endothelial dysfunction in several vascular disorders including aging. However, published reports on healthy arteries using low temperature SDS-PAGE has revealed considerable variation between studies in the relative expression of eNOS dimers and monomers. While assessing structural uncoupling of eNOS in aging arteries, we identified methodological pitfalls that might contribute to such variation. Experiments therefore investigated optimal approaches for analyzing expression of eNOS monomers and dimers, using human cultured aortic endothelial cells and aortas from young and aged F344 rats. The results demonstrate that published differences in treatment of cellular lysates can significantly impact the relative expression of several eNOS species including denatured monomers, partially-folded monomers, dimers and higher-order oligomers. In aortas, experiments initially confirmed a large increase in eNOS monomers in aging arteries, consistent with structural uncoupling. However, these monomers were actually endogenous IgG, which under these conditions has similar mobility to eNOS monomers. Increased IgG levels in aged aortas likely reflect the aging-induced disruption of endothelial junctions and increased arterial penetration of IgG. After removing the IgG signal, there was low levels of eNOS monomers in young arteries, which were not significantly different in aged arteries. Therefore, structural uncoupling of eNOS is not a prominent feature in young healthy arteries and the process is not increased by aging. The study also identifies optimal approaches to analyze eNOS dimers and monomers. PMID- 30289293 TI - Sex-specific effects of advanced maternal age on cardiovascular function in aged adult rat offspring. AB - Pregnancy at an advanced maternal age has an increased risk of complications for both the mothers and their offspring. We have previously shown that advanced maternal age in a rat model leads to poor fetal outcomes, maternal vascular dysfunction and hypertension, concordant with findings in humans. Moreover, offspring from aged dams had sex-specific cardiovascular dysfunction in young adulthood. Yet, the detrimental impact of aging on the cardiovascular system of the offspring in this model is unknown. We hypothesized that offspring born to aged dams (9.5-10 months old) would have impaired cardiovascular function at 12 months of age. Echocardiographic data revealed signs of mild left ventricular (LV) diastolic dysfunction in only male offspring from aged dams (Isovolumetric relaxation time (IVRT); young 34.27+/-2.04 vs. aged dam 27.61+/-0.99 msec; P<0.01 and E'/A'; young 1.08+/-0.04 vs. aged dam 0.96+/-0.02; P<0.05). In young adulthood (4 months of age), we previously showed that male, but not female, offspring born from aged dams had impaired recovery from ischemia/reperfusion (I/R) injury. Aging did not alter the susceptibility of female offspring to I/R injury. Interestingly, wire myography data revealed that male offspring from aged dams had enhanced vascular sensitivity to methacholine (MCh pEC50: young 7.4+/ 0.08 vs. aged dam 7.9+/-0.11; P=0.007) due, in part, to increased prostaglandin mediated vasodilation. Despite intact endothelium-dependent relaxation, female offspring from aged dams had elevated systolic blood pressure (young 125.3+/-4.2 mmHg vs. aged dam 144.0+/-6.9 mmHg, P=0.03). These data highlight sex-specific mechanisms underlying cardiovascular programming in offspring born to dams of advanced age. PMID- 30289294 TI - Sex Differences in the Central and Peripheral Manifestations of Ischemia-induced Heart Failure in Rats. AB - Sex differences in the presentation, outcome and responses to treatment of systolic heart failure (HF) have been reported. We examined the effect of sex on central neural mechanisms contributing to neurohumoral excitation and its peripheral manifestations in HF rats. Male and female SD rats underwent coronary ligation (CL) to induce HF. Age-matched rats served as controls. Infarct size and left ventricular function were similar 24 hours and 4 weeks after CL. Female HF rats had a lower mortality rate and less hemodynamic compromise, pulmonary congestion and right ventricular remodeling 4 weeks after CL. Plasma angiotensin II (ANG II), arginine vasopressin (AVP) and norepinephrine levels were increased in HF rats in both sexes, but AVP and norepinephrine levels increased less in females. In hypothalamic paraventricular nucleus, a key cardiovascular-related nucleus contributing to neurohumoral excitation in HF, mRNA levels for the pro inflammatory cytokines tumor necrosis factor-alpha and interleukin-1beta, cyclooxygenase-2, and the ANG II type 1a receptor were increased in HF rats of both sexes, but less so in females. Angiotensin converting enzyme 2 protein increased in female HF rats but decreased in male HF rats. AVP mRNA was lower in both control and HF females, compared with the respective males. ERK1/2 activity increased similarly in both sexes in HF. The results suggest that female HF rats have less central neural excitation and less associated hemodynamic compromise than male HF rats with the same degree of initial ischemic cardiac injury. PMID- 30289295 TI - ENDOCRINOLOGY FELLOWS' PERCEPTION OF THEIR CONFIDENCE AND SKILL LEVEL IN PROVIDING TRANSGENDER HEALTHCARE. AB - OBJECTIVE: Both educational content and hours devoted to transgender health training of endocrinology fellows are suboptimal. The objective of this study was to assess the perspectives of endocrinology fellows on their training in transgender health. METHODS: We evaluated the state of comfort and knowledge of transgender healthcare among endocrinology fellows attending Endocrine University. Pre- and post-surveys were administered to fellows following participation in a case-based session on transgender health. RESULTS: The majority of fellows felt that training in transgender health is important (95.9% 189/197); however only 58.9% reported inclusion of dedicated transgender content in their training programs. Fellows who had received transgender healthcare education, and those who had seen more transgender patients in their training, were more likely to be confident in treating patients with hormone therapy (P<0.001 and p<0.0001, respectively). Following the case-based session, 62.4 % of fellows reported that they would change their practice, 72.8% felt that their comfort level with transgender care had improved, and 91% felt that transgender content such as that provided in the educational session should be mandatory in endocrinology training programs. Methods most desired by fellows to improve their education included lectures from visiting professors (70.3%), participation in elective rotations (62.1%), online training modules (57.9%), and attendance at meetings with transgender topics (57.4%). CONCLUSION: Transgender health education of US endocrinology fellows is suboptimal. Participation in a case based session significantly increased the comfort level of endocrinology fellows in key areas of transgender health.

PMID- 30289298 TI - THE CLINICAL PRESENTATION OF PRIMARY HYPERPARATHYROIDISM: A SOUTHERN EUROPEAN PERSPECTIVE OVER THE LAST TWO DECADES. AB - BACKGROUND: The clinical presentation of primary hyperparathyroidism (PHPT) has changed widely in developed countries in the last few decades. We evaluated its variations in our series over a 20-year period, i.e. 1997-2016. PATIENTS: A retrospective survey was conducted in our series of 364 well-characterized consecutive patients, arbitrarily divided into four consecutive 5-year periods at diagnosis. RESULTS: In the overall series, only eGFR and urinary calcium showed a significant upward trend (p=0.032 and 0.039, respectively), whereas demographic and clinical characteristics were stable. The urinary calcium upward trend was confirmed also for the subgroup of symptomatic patients (p=0.013). No difference was observed in the demographic, clinical and biochemical characteristics of asymptomatic patients, or in the fraction of patients meeting surgical criteria. CONCLUSIONS: Clinical presentation of PHPT was stable over 20 years in our large series.

PMID- 30289299 TI - PRIMARY HYPERPARATHYROIDISM IN THE YOUNG: COMPARISON WITH THE ADULT PRIMARY HYPERPARATHYROIDISM. AB - OBJECTIVES: Primary hyperparathyroidism (PHPT) is relatively common among adults; however, rarely encountered in children and adolescents. According to the western literature, young PHPT is different from adult PHPT and is associated with more severe hypercalcaemia. PHPT in adult Indian population is different from its western counterpart. Here we present the clinical, biochemical and surgical characteristics of young PHPT from our tertiary care centre. METHODS: PHPT patients were divided into adult (age >=25 years) and young (age <25 years) PHPT groups. The clinical, biochemical, hormonal, histopathological characteristics and treatment outcome of young PHPT patients were compared with adult PHPT patients. RESULTS: Out of total 358 patients, 47 patients were young and 311 patients were adult PHPT. The mean age of young and adult patients were19+/-4 and 45+/-12 years, respectively; with female to male ratio of 1.24:1 and 3.38:1, respectively (p<0.05). The nature and frequency of presenting symptoms were comparable between the two groups. The most common symptom in young PHPT was bone pain, and was not significantly different from adults (57% vs. 61%, respectively). While, the most common symptom in adult PHPT was fatigue, which was also not significantly different from young patients (63% vs. 53% respectively), The serum calcium, phosphate, 25(OH)D, ALP Z-score and PTH levels were comparable between the two groups. Parathyroid adenoma was the commonest histopathological finding, while hyperplasia was rare in both the groups. CONCLUSIONS: In this series of young PHPT, we observed that young PHPT is not much different from adult counterpart in Indian scenario.

PMID- 30289300 TI - MANAGEMENT OF THYROTOXICOSIS: PRECONCEPTION, PREGNANCY, AND THE POSTPARTUM PERIOD. AB - OBJECTIVE: To review the diagnosis and management of thyrotoxicosis in women who are preconception, pregnant, and in the postpartum period. METHODS: Literature review of English-language papers published 1980-2018. RESULTS: Overt thyrotoxicosis occurs in 0.2% of pregnancies and subclinical thyrotoxicosis in 2.5%. Hyperthyroidism in women of childbearing age most frequently is caused by Graves' disease. Gestational thyrotoxicosis, transient hCG-mediated hyperthyroidism, may develop in the first trimester of pregnancy. In the first year following delivery, postpartum thyroiditis, which frequently includes a thyrotoxic phase, occurs in 5% of women. Hyperthyroidism from nodular autonomy is uncommon in women of childbearing age. It is essential to understand the underlying etiology for thyrotoxicosis in order to recommend appropriate treatment. Gestational thyrotoxicosis requires supportive care, without anti thyroid drug therapy. Graves' disease may be treated with anti-thyroid drugs, radioactive iodine, or thyroidectomy. Pregnancy, plans for pregnancy, and lactation have important implications for the choice of Graves' disease treatment. When thyrotoxicosis presents following delivery, postpartum thyroiditis must be differentiated from Graves' disease. CONCLUSION: The diagnosis and management of thyrotoxicosis in the peri-pregnancy period present specific challenges. In making management decisions it is essential to weigh the risks and benefits of treatments not just for the mother but also for the fetus, and for breastfed infants. A team approach to management, with close collaboration between endocrinologists, maternal-fetal medicine specialists, and neonatologists, is essential.

PMID- 30289302 TI - PROACTIVE PROTOCOL-BASED MANAGEMENT OF HYPERGLYCEMIA AND DIABETES IN COLORECTAL SURGERY PATIENTS. AB - OBJECTIVE: The management of diabetic patients undergoing elective abdominal surgery continues to be unsystematic, despite evidence that standardized perioperative glycemic control is associated with fewer postoperative surgical complications. We examined the efficacy of a pre-operative diabetes optimization protocol implemented at a single institution in improving perioperative glycemic control with a target blood glucose of 80 to 180 mg/dL. METHODS: Patients with established and newly diagnosed diabetes who underwent elective colorectal surgery were included. The control group comprised 103 patients from January 1, 2011, through December 31, 2013, before protocol implementation. The glycemic optimized group included 96 patients following protocol implementation from January 1, 2014, through July 31, 2016. Data included demographic information, blood glucose levels, insulin doses, hypoglycemic events, and clinical outcomes (length of stay, re-admissions, complications, and mortality). RESULTS: Patients enrolled in the glycemic optimization protocol had significantly lower glucose levels intra-operatively (145.0 mg/dL vs. 158.1 mg/dL; P = .03) and postoperatively (135.6 mg/dL vs. 145.2 mg/dL; P = .005). A higher proportion of patients enrolled in the protocol received insulin than patients in the control group (0.63 vs. 0.48; P = .01), but the insulin was administered less frequently (median [interquartile range] number of times, 6.0 [2.0 to 11.0] vs. 7.0 [5.0 to 11.0]; P = .04). Two episodes of symptomatic hypoglycemia occurred in the control group. There was no difference in clinical outcomes. CONCLUSION: Improved peri operative glycemic control was observed following implementation of a standardized institutional protocol for managing diabetic patients undergoing elective colorectal surgery.

PMID- 30289304 TI - PITUITARY EVALUATION IN PATIENTS WITH LOW PROSTATE SPECIFIC ANTIGEN. AB - OBJECTIVE: To evaluate pituitary function in men with a low screening PSA of <=0.1 ng/ml, and test the hypothesis that low PSA is associated with hypogonadism alone or other hormone deficiency. METHODS: This is a case-controlled study evaluating the rates of hypogonadism and low IGF-1 in a cohort of men, with low or normal screening PSA level. Sixty-four men >40 years old without known prostate disease were divided into low PSA group (PSA <=0.1 ng/ml) and normal PSA group (PSA 1-4 ng/ml). Hormonal evaluation included total testosterone, prolactin, LH, FSH, IGF-1, GH, TSH, FT4, AM cortisol, and ACTH. The difference between each patient's observed IGF-1 and the IGF-1 age-specific lower limit was calculated. The odds ratios (OR) for having hypogonadism and associated 95% confidence intervals were calculated using the Cochran-Mantel-Haenszel test. RESULTS: The rate of hypogonadism was significantly higher in the low PSA group (N=44) compared with the normal PSA control group (N=20) (45.5% vs. 15.0%, OR = 4.7, 95% CI for OR = 1.2 to 18.4, p = 0.027). The total testosterone in the low PSA group was significantly lower compared with control group (181.7 vs. 263.7 ng/dl, p = 0.008). IGF-1 values were below their lower bound in 18.6 % of subjects in the low PSA group, compared with 0% in the control group. CONCLUSION: Men with low PSA have significantly higher rates of hypogonadism and low IGF-1 compared with those with normal PSA. In such men, we recommend hormonal evaluation to exclude associated pituitary dysfunction.

PMID- 30289305 TI - ASSOCIATIONS OF SERUM IONIZED CALCIUM, PHOSPHATE, AND PTH LEVELS WITH TECHNETIUM 99 SESTAMIBI PARATHYROID SPECT/CT SCAN IN PRIMARY HYPERPARATHYROIDISM. AB - OBJECTIVE: To evaluate the relationship between various biochemical parameters in patients with PHPT with positive and negative technetium-99 sestamibi parathyroid scans SPECT/CT (Tc scan). METHOD: Retrospective analysis. Development of a logistic probability model. There were 218 patients with PHPT evaluated. Main outcome measures were serum total calcium, ionized calcium, intact PTH, albumin, alkaline phosphatase, phosphate, 25-hydroxy vitamin D, 1,25-dihydroxy vitamin D, 24-hour urine calcium levels and parathyroid adenoma weight. RESULTS: Individually, using cut-off levels of 6.0 mg/dL for ionized calcium, 3.0 mg/dL for phosphate, and 90 pg/mL for intact PTH, we found that 91.3% (p=0.005) , 70.7% (p=0.004) and 87.90% (p=0.023) of the patients had a positive Tc scan with their corresponding strengths of associations in the parentheses. Similar significant association was sustained in multivariate setting for serum ionized calcium (p = 0.015), phosphate (p=0.016) and intact PTH (p=0.028). A logistic probability model was designed to predict the probability of being positive for Tc scan given a set of covariates. CONCLUSION: There is a significant association between the levels of serum ionized calcium, phosphate, intact PTH, and the positivity of Tc scan. Further studies with larger patient populations are needed.

PMID- 30289307 TI - RISK FACTORS FOR CENTRAL LYMPH NODE METASTASES IN PATIENTS WITH PAPILLARY THYROID MICROCARCINOMA. AB - OBJECTIVES: Papillary thyroid carcinoma with a maximum tumor diameter no more than 10 mm is defined as papillary thyroid microcarcinoma (PTMC). The proportion of newly diagnosed PTMC has increased significantly in recent years. Different guidelines have different comments about optimal management of PTMC, especially on prophylactic central lymph node (CLN) dissection. The aim of the present study is to analyze the risk factors for CLN metastases in patients with PTMC. METHODS: A total of 4389 patients underwent thyroid surgery at our center from January 2017 to March 2018, and 2129 patients with PTMC were selected and assessed retrospectively. The relationship between CLN metastases and clinicopathologic features of PTMC were analyzed by both univariate and multivariate analyses. RESULTS: Of the 2129 patients with PTMC, CLN metastases were confirmed by pathology in 923 patients. Univariate and multivariate analyses found several independent factors associated with CLN metastases. They were male gender (OR=1.694, 95% CI 1.386 - 2.071; p<0.001), younger age (< 45 years) (OR=2.687, 95% CI 2.196 - 3.288; p<0.001), larger tumor size (> 5 mm) (OR=2.168, 95% CI 1.782 - 2.636; p<0.001), positive CLN metastases via ultrasound (OR=4.939, 95% CI 3.534 - 6.902; p<0.001), and multifocality (OR=1.424, 95% CI 1.176 - 1.724; p<0.001). CONCLUSION: CLN metastases are common in PTMC patients. Male gender, younger age (< 45 years), larger tumor size (> 5 mm), positive CLN metastases via ultrasound, and multifocality are independent factors for CLN metastases. Our data should be considered in the decision process relating to performing CLN dissection.

PMID- 30289308 TI - GOALS FOR MEDICAL TREATMENT IN OBESITY AND PREDIABETES: IMPROVING OUTCOMES FOR BOTH. AB - OBJECTIVE: The purpose of this review is to expose the surprising prevalence of diabetes-related complications in people with persistent prediabetes, and hence, to expand the paradigm of diabetes prevention to include the prevention of complications related to both hyperglycemia and obesity. METHODS: Published literature was reviewed. RESULTS: Approximately 84 million Americans have prediabetes, 85% of whom are overweight or obese. Although the incidence of diabetes-related complications is lower in people with prediabetes vs. type 2 diabetes, the overall prevalence is virtually identical. Further, many people with prediabetes not only suffer from the complications of related to hyperglycemia, they also experience complications of obesity. Treating obesity as a disease has the potential to prevent complications of both hyperglycemia and obesity. Emerging data reveals the untapped potential for clinicians to enhance the effectiveness of anti-obesity medications through a mindful health care delivery style. This involves an understanding and ethical utilization of the placebo effect in conjunction with active medical therapy. This approach is not intended to mislead patients, but rather to activate neurocircuitry that synergizes with the central action of the approved anti-obesity medications to potentiate weight loss. CONCLUSIONS: Mindful administration of anti-obesity medications has the potential for widespread health benefits in people with obesity and prediabetes.

AB - OBJECTIVE: The patterns of emergency department (ED) visits in patients with diabetes are not well understood. The Emergency Department Diabetes Rapid referral Program (EDRP) allows direct booking of ED patients presenting with urgent diabetes needs into a diabetes specialty clinic within 1 day of ED discharge. The objective of this secondary analysis was to examine characteristics of patients with diabetes who have frequent ED visits and determine reasons for revisits. METHODS: A single-center analysis was conducted comparing patients referred to the EDRP (n = 420) to historical unexposed controls (n = 791). The primary outcome was the proportion of patients in each frequency group of ED revisits (none, 1 to 3 [infrequent], 4 to 10 [frequent], or >10 [superfrequent]) in the year after the ED index visit. Secondary outcomes were hospitalization rates and International Classification of Diseases-Ninth Revision (ICD-9) diagnoses at ED revisits. RESULTS: Superfrequent users, responsible for >20% of total ED visits, made up small but not significantly different proportions of EDRP and control populations, 3.6% and 5.2%, respectively. Superfrequent groups had lower hospital admission rates at ED revisits compared to frequent groups. Mental health disorders (including substance abuse) were the primary, secondary, or tertiary ICD-9 codes in 30.6% (95% confidence interval [CI], 27.7% to 33.5%) and 6.6% (95% CI, 5.1% to 8.2%) in the superfrequent and infrequent groups, respectively. CONCLUSION: Direct access to diabetes specialty care from the ED is effective in reducing ED recidivism but not amongst a small subgroup of superfrequent ED users. This group was more likely to have mental health disorders recorded at ED revisits, suggesting that more comprehensive approaches are needed for this population.

AB - OBJECTIVE: To review literature and present a schematic approach to Hypophosphatasia (HPP) evaluation and management applicable to practicing physicians to ease its recognition and diagnosis. METHODS: Studies were obtained from online databases PubMed and MEDLINE using keyword Hypophosphatasia. RESULTS: HPP is a rare disease characterized by low serum alkaline phosphatase, along with diverse musculoskeletal symptoms, that mimic different disorders. To date, the prevalence of HPP and its impact on adults has been unrecognized. There is lack of evidence of larger and long term studies examining the adult type of this condition. CONCLUSION: It is essential to increase awareness on the complexity of the pathophysiology and clinical features of Hypophosphatasia. HPP causes debilitating physical conditions which severely affects quality of life. A better comprehension of adult forms of HPP is essential to reduce a delay in diagnosis, as well as suitable management.

PMID- 30289313 TI - CALCIUM CREATININE CLEARANCE RATIO IS NOT HELPFUL IN DIFFERENTIATING PRIMARY HYPERPARATHYROIDISM FROM FAMILIAL HERPERCALCEMIC HYPOCALCIURIA: A STUDY OF 1000 PATIENTS. AB - OBJECTIVE: With increasing recognition of more subtle presentations of primary hyperparathyroidism (pHPT), laboratory values are frequently seen in a range that would be expected for patients who have familial hypercalcemic hypocalciuria (FHH). Calcium creatinine clearance ratio (CCCR) has been advocated as a diagnostic tool to differentiate between these two disorders. However, it is limited by an indeterminate range (0.01-0.02). The aim of this study is to assess the relevance of CCCR in a modern series of patients with surgically managed pHPT. METHODS: We performed a retrospective cohort study of 1000 patients who underwent parathyroid surgery for pHPT over eleven years. CCCR was evaluated by degree of biochemical derangement, single versus multiple gland disease and interfering medications. RESULTS: Patient demographics and resected histopathology were typical for a current series of patients with pHPT. In retrospect, none of the patients were suspected to have FHH post operatively. CCCR was less than 0.01 for 19.0%, between 0.01-0.02 for 43.7% and greater than 0.02 in 37.3%. Distribution of CCCR for patients free from interfering medications and different histological subtypes were the same. One third of the cohort had mild calcium elevations, more typical for FHH. Of these, almost two thirds had a CCCR in a range suspect for FHH (<0.02). CONCLUSION: To our knowledge this is the largest series to evaluate the validity of CCCR for patients with surgically confirmed pPHT. The utility of CCCR in screening for FHH is limited, as 63% of modern patients with confirmed pHPT have low values. PMID- 30289314 TI - MAKING A DIFFERENCE IN ADRENAL FATIGUE. PMID- 30289315 TI - REGULATION OF FREE FATTY ACIDS BY SITAGLIPTIN MONOTHERAPY IN DRUG NAIVE SUBJECTS WITH TYPE 2 DIABETES. AB - OBJECTIVES: The aim of this study is to investigate the effects of sitagliptin on the regulation of FFA and other metabolic parameters in drug-naive subjects with T2DM. SUBJECTS AND METHODS: This is a prospective, non-randomized, observational study. Drug naive subjects with T2DM received 25-50 mg/day sitagliptin monotherapy (n=64). At 3 months, FFA and other metabolic parameters were compared with those at baseline. FFA was measured by colorimetry with enzymatic reactions. As a comparator, 12.5-25mg/day alogliptin monotherapy was given to drug naive subjects with T2DM (n=55). RESULTS: Significant reductions in FFA (-13.2 %, p<0.01) levels were observed with sitagliptin, however, not with alogliptin. Both drugs showed similar glycemic efficacies. Significant correlations were observed between the changes (Delta) of FFA and DeltaHbA1c, DeltaT-C, Deltanon-HDL-C or DeltaLDL-C, and significant negative correlations were seen between DeltaFFA and DeltaHOMA-B, DeltaCPR-index or DeltaBMI in the sitagliptin group. The subjects in the sitagliptin group were further divided into two subgroups (n=32 each) according to the changes of FFA (group B [above the median] DeltaFFA =23.1 %, p<0.0005; group A [below the median] DeltaFFA=-37.3 %, p<0.00001). At baseline, FFA levels were significantly higher in group A versus group B (p<0.001). Higher degrees of reductions of FBG (-14.6% vs. -9.3%, p<0.05) or HbA1c (-20.6% vs. 16.9%, p<0.05), and increases of HOMA-B (52.7% vs. 38.3%, p<0.03) or CPR-index (37.5% vs. 18.8%, p<0.02) were observed in group A versus group B. Significant reductions of T-C (-5.8%, p<0.002), non-HDL-C (-7.8%, p<0.001) or LDL-C (-6.3%, p<0.02), and significant increases of C-peptide (11.3%, p<0.05) were seen only in group A. CONCLUSIONS: Sitagliptin could down-regulate high FFA levels. Subjects with reductions of FFA levels had better glycemic efficacies and higher degrees of enhancement of beta-cell function than others. Reductions of atherogenic cholesterols were seen in these populations.

METHOD: Children (N = 3) between the ages of 2-3 years who were diagnosed with CP classified as GMFCS levels IV and V participated in BWSTT three times per week. The Segmental Assessment of Trunk Control (SATCo) and the gross motor function measure (GMFM-66) were assessed before and after the 6-week intervention. RESULTS: Final testing revealed that all participants improved on the SATCo and GMFM. CONCLUSION: BWSTT is a viable intervention that may improve trunk control and gross motor outcomes in young children with severe CP. Further research is needed to explore the impact of BWSTT for young children classified as GMFCS levels IV and V.

DESIGN: Exploratory qualitative design. SETTING: HCPs who perform CCS: general practitioners, midwives and private gynaecologists, working in Oslo, Norway. SUBJECTS: We interviewed 26 general practitioners, 3 midwives and 3 gynaecologists. METHOD: Both focus groups and personal in depth semi structured interviews. Interview transcripts were analysed using a thematic analysis approach. RESULTS: Some of the HCPs' experiences related to CCS were common for all women regardless of their immigrant background, such as the understanding of routines and responsibilities for prevention. Aspects specific for immigrant women were mainly related to organization, language, health literacy levels, culture and gender. Several strategies targeting organizational (longer consultations), language (using interpreters), health literacy (using anatomy models to explain) and culture (dealing with the expression of pain) were reported. Most HCPs had not previously reflected upon specific challenges linked to CCS among immigrant women, thus the interviews were an eye-opener to some extent. HCPs acknowledged that they need more knowledge on immigrant women's' reproductive health. CONCLUSION: HCPs' biases, stereotypes and assumptions could be a key provider-level barrier to low uptake of CCS test among immigrants if they remained unexplored and unchallenged. HCPs need more information on reproductive health of immigrant women in addition to cultural awareness. Key Points The participation rate of immigrant women to cervical cancer screening in Norway is low, compared to non-immigrants. This might be partly attributed to health care system and provider, and not only due to the women's preferences. Our focus groups and interviews among health care providers show, that in addition to cultural competence and awareness, they need knowledge on reproductive health of immigrants. We recommend an intervention targeting health care providers to close the gap in cervical cancer screening.

AB - PURPOSE: To investigate whether significant differences exist in everyday memory between youth with Fetal Alcohol Spectrum (FASD) compared with a nonexposed (NE) control group, while controlling for socioeconomic status and other comorbidities. METHODS: Caregiver ratings using the Everyday Memory Questionnaire were obtained for 105 youth (9-17 years of age). Scores were compared between youth with a FASD diagnosis (N = 41; 56% male) and the NE group (N = 64; 53% male) using multivariate analysis of variance. RESULTS: Significantly poorer scores were found across all domains of everyday memory in youth with FASD (p<0.01 for all comparisons). Findings maintained significance after controlling for group differences in socioeconomic status, presence of learning, and attention disorders, as well as exposure to other teratogens. CONCLUSIONS: This study provides important insights regarding the memory issues that underlie daily functional challenges faced by youth with FASD and the need for future intervention research. PMID- 30289319 TI - Novel causative variants in patients with achromatopsia. AB - PURPOSE: To report five novel genetic variants in seven unrelated consanguineous families with achromatopsia (ACHM). METHODS: Patients were examined with multimodal retinal imaging and full-field electroretinography (ffERG). Genetic testing was conducted using next-generation sequencing (NGS). RESULTS: Three novel homozygous variants were detected in CNGA3: a missense c.967G > C (p.Ala323Pro) variant was detected in exon 8 (one patient), a splice site variant c.101 + 1G > A in intron 2 (three patients), and a splice site variant c.395 + 1G > T in intron 4(one patient). Another two novel variants were found in PDE6C: a homozygous missense variant c.1899C > A (p.His633Gln) in exon 15 (one patient) and a homozygous splice site variant c.1072-1G > C in intron 7 (one patient). Mutation segregation assessment was possible in 3 of the 7 families. All patients had nonrecordable ffERG 30-Hz flicker responses, reduced single-flash cone responses but preserved rod responses. Patients presented with variable degrees of foveal outer retinal layer loss and variable patterns of foveal hyperautofluorescence. CONCLUSIONS: These novel variants expand the genotypes associated with ACHM and may help in future therapy development for ACHM. PMID- 30289320 TI - First four years of operation of a municipal acute bed unit in rural Norway. AB - OBJECTIVE: To evaluate the use of a small municipality acute bed unit (MAU) in rural Norway resulting from the Coordination reform regarding occupancy-rate, patient characteristics and healthcare provided during the first four years of operation. Further, to investigate whether implementation of the new municipal service avoided acute hospital admissions. DESIGN: Observational study. SETTING: A two-bed municipal acute bed unit. SUBJECTS: All patients admitted to the unit between 2013 and 2016. MAIN OUTCOME MEASURES: Demographics, comorbidity, main diagnoses and level of municipal care on admission and discharge, diagnostic and therapeutic initiatives, MAU occupancy rate, and acute hospital admission rate. RESULTS: Altogether, 389 admissions occurred, 215 first-time admissions and 174 readmissions. The mean MAU bed occupancy rate doubled from of 0.26 in 2013 to 0.50 in 2016, while acute hospital admission rates declined. The patients (median age 84.0 years, 48.9% women at first time admission) were most commonly admitted for infections (28.0%), observation (22.1%) or musculoskeletal symptoms (16.2%). Some 52.7% of the patients admitted from home were discharged to a higher care level; musculoskeletal problems as admission diagnosis predicted this (RR =1.43, 95% CI 1.20-1.71, adjusted for age and sex). CONCLUSION: Admission rates to MAU increased during the first years of operation. In the same period, there was a reduction in acute hospital admissions. Patient selection was largely in accordance with national and local criteria, including observational stays. Half the patients admitted from home were discharged to nursing home, suggesting that the unit was used as pathway to a higher municipal care level. Key Points Evaluation of the first four years of operation of a municipality acute bed unit (MAU) in rural Norway revealed: * Admission rates to MAU increased, timely coinciding with decreased acute admission rates to hospital medical wards. * Most patients were old and had complex health problems. * Only half the patients were discharged back home; musculoskeletal symptoms were associated with discharge to a higher care level. PMID- 30289321 TI - An evaluation of the additive effects of lag schedules of reinforcement. AB - Lag schedules of reinforcement represent an increasingly researched strategy for addressing restricted and repetitive social communication of individuals with autism spectrum disorder (ASD). Although the body of literature suggests that lag schedules of reinforcement are generally effective for this purpose, studies have varied in their utilization of verbal rules describing the contingency. Furthermore, research has yet to evaluate generalized effects of lag schedules of reinforcement to social communication with peers. This study evaluated the implementation of a social skills curriculum, modified to incorporate lag schedules of reinforcement, on novel responding of participants with ASD. Participants attended training twice per week, with probes of novel responding collected with both researchers and non-participating peers. Results indicate that social skills training that incorporated lag schedules of reinforcement generally resulted in larger increases in novel responding than social skills training alone. Furthermore, effects of training generalized to novel responding to non-participant peers. PMID- 30289322 TI - Association analysis of genetic polymorphisms and expression levels of selected genes involved in extracellular matrix turnover and angiogenesis with the risk of age-related macular degeneration. AB - BACKGROUND: Age-related macular degeneration is a progressive eye disease affecting the macula and causing acute visual loss particularly in elder people. The aim of the study was an attempt to discern an influence of expression levels and functional genetic polymorphisms of selected genes related to the extracellular matrix turnover or neovascularization on age-related macular degeneration occurrence and progression. METHODS: We conducted a case-control study of 200 polish patients with recognized age-related macular degeneration (dry and wet) and compared the results with those obtained from matched 100 healthy control subjects. TaqMan Genotyping Assays were employed to examine the following single nucleotide polymorphisms: matrix metalloproteinase (MMP)-2 735C/T, MMP-7 -181A/G, MMP-9 -1702T/A, and -1562C/T; tissue inhibitors of metalloproteinase (TIMP)-2 -418G/C; vascular endothelial growth factor (VEGF) +405 G/C and +936 C/T, VEGFR-2 +1719 T/A and -271 G/A. Real-time polymerase chain reaction was assessed to determine the mRNA quantity. Serum levels of proteins were measured using enzyme-linked immunosorbent assay. RESULTS: The single nucleotide polymorphism genotyping showed that TT genotype for MMP-9 -1702T/A and CC genotype for VEGF +936C/T increase markedly the risk of age-related macular degeneration but do not influence on its progression. Additionally, the possible protective effect of CC genetic variant in MMP-9 -1562C/T polymorphism against progression of age-related macular degeneration was observed. We also found significant differences in systemic expression levels of MMP-2, -7, -9, TIMP-2, vascular endothelial growth factor, VEGFR-2, and pigment epithelium-derived factor between studied group. The research demonstrated evident differences in serum levels of MMP-2, -7, -9, TIMP-2, vascular endothelial growth factor, and pigment epithelium-derived factor between wet and dry age-related macular degeneration patients. CONCLUSIONS: We can conclude that disturbances in angiogenic homeostasis and processes of extracellular matrix turnover occurring in age-related macular degeneration-affected ocular tissues may be reflected in changes in systemic expression levels of the investigated genes. PMID- 30289324 TI - Management of Polyarthritis Affecting Sea Turtles at Kelonia, the Reunion Island Sea Turtle Observatory (2013-17). AB - All sea turtle species are listed on the Red List of the International Union for the Conservation of Nature due to multiple threats. Among these, disease is a frequent cause of stranded sea turtles encountered in rehabilitation centers. Since 2013, we found joint swelling in 13 sea turtles belonging to all four sea turtle species submitted to the Kelonia Sea Turtle Observatory of Reunion Island, France. Affected sea turtles presented with lameness, anorexia, and lethargy. Polyarthritis was radiographically confirmed and lesions were characterized by progressive osteolysis of bones surrounding joints. Anterior flippers were affected in all cases and posterior flippers were also involved in some cases. We isolated several bacterial agents from blood and synovial fluid. We attempted a collective treatment with injectable florfenicol, based on sensitivity results, which was continued for 4 wk and then as needed based on radiographic evolution of the lesions. Radiographic stabilization of the lesions occurred in nine of 13 cases. We reviewed environmental conditions and optimized them to minimize stress that could predispose these rehabilitated sea turtles to opportunistic infections. Handling techniques used to move sea turtles were also improved. While we can make no conclusion regarding the cause of polyarthritis in this population of sea turtles, we successfully managed this poorly described problem in a rehabilitation setting.

AB - Given the limited number of pediatric-specific palliative care programs, palliative care providers of all disciplines may be called on to care for infants, children, and adolescents with serious illness. This article provides a review of the unique components of pediatric palliative care, including key roles within an interdisciplinary team, pediatric developmental considerations, use of medical technology and complexities of symptom management in children with serious illness, hospice utilization, as well as pointers for discussions with families regarding a patient's quality of life and goals of care. PMID- 30289326 TI - Serologic Survey of Selected Viral Pathogens in Free-Ranging Eurasian Brown Bears ( Ursus arctos arctos) from Slovakia. AB - We tested sera of 24 free-ranging European brown bears ( Ursus arctos) from six regions of Slovakia for antibodies to 10 viral agents. We tested sera by an indirect fluorescence antibody test for antibodies to canine distemper virus (CDV), canine coronavirus (CCV), canine parvovirus type 2 (CPV-2), canine adenovirus, canine parainfluenza virus type 2 (CPIV-2), and canine herpesvirus type 1 (CHV-1). We used an enzyme-linked immunosorbent assay for detection of antibodies to hepatitis E virus, bluetongue virus, West Nile virus (WNV), and Aujeszky's disease virus (ADV). We detected antibodies to CDV, CHV-1, CPV-2, CPIV 2, CCV, WNV, and ADV in seven (29%), three (12%), two (8%), two (8%), one (4%), one (4%), and one (4%) bear, respectively. Evidence of exposure of free-ranging European brown bears to CCV and ADV has not been reported. PMID- 30289327 TI - Long-term quality of life after comprehensive surgical staging of high-risk endometrial cancer - results from the RASHEC trial. AB - PURPOSE: The health-related quality of life (HRQoL) outcomes after comprehensive surgical staging including infrarenal paraaortic lymphadenectomy in women with high-risk endometrial cancer (EC) are unknown. Our aim was to investigate the long-term HRQoL between robot-assisted laparoscopic surgery (RALS) and laparotomy (LT). PATIENTS AND METHODS: A total of 120 women with high-risk stage I-II EC were randomised to RALS or LT for hysterectomy, bilateral salpingoophorectomy, pelvic and infrarenal paraaortic lymphadenectomy in the previously reported Robot Assisted Surgery for High-Risk Endometrial Cancer trial. The HRQoL was measured with the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-30) and its supplementary questionnaire module for endometrial cancer (QLQ-EN24) questionnaire. Women were assessed before and 12 months after surgery. In addition, the EuroQol Eq5D non-disease specific questionnaire was used for descriptive analysis. RESULTS: There was no difference in the functional scales (including global health status) in the intention to treat analysis, though LT conferred a small clinically important difference (CID) over RALS in 'cognitive functioning' albeit not statistically significant -6 (95% CI-14 to 0, p = .06). LT conferred a significantly better outcome for the 'nausea and vomiting' item though it did not reach a CID, 4 (95% CI 1 to 7, p = .01). In the EORTC-QLQ/QLQ-EN24, no significant differences were observed. Eq5D-3L questionnaire demonstrated a higher proportion of women reporting any extent of mobility impairment 12 months after surgery in the LT arm (p = .03). CONCLUSION: Overall, laparotomy and robot-assisted surgery conferred similar HRQoL 12 months after comprehensive staging for high-risk EC. PMID- 30289328 TI - Hematologic and Serum Chemistry Values of Endangered San Joaquin Kit Foxes ( Vulpes macrotis mutica) with Sarcoptic Mange. AB - A fatal outbreak of sarcoptic mange caused by Sarcoptes scabiei in San Joaquin kit foxes ( Vulpes macrotis mutica) in Bakersfield, California, USA is causing the once-stable population to decline. Given the fatality of the disease in this already-endangered species experiencing continued population declines, city-wide interventions are underway. To optimize medical management of mange-infested kit foxes, we documented serum biochemistry and hematology values for 11 kit foxes with mange collected from January-May 2015 and compared them to historical data from 18 healthy Bakersfield kit foxes. Results from kit foxes with mange were consistent with chronic illness and inflammation, protein loss, hypoglycemia, and dehydration. These findings contribute to our understanding of this debilitating, multisystemic disease that can progress to death in individuals without intervention and will aid in the treatment and care of rehabilitated individuals. PMID- 30289329 TI - Topical Cyclosporine Pretreatment of Ocular Surface in Allogeneic Hematopoietic Stem Cell Transplant Recipients. AB - PURPOSE: Dry eye disease (DED) of ocular graft-versus-host disease (GVHD) is a common complication after allogeneic hematopoietic stem cell transplantation (HSCT). Ongoing inflammation and irreversible fibrotic changes of the ocular surface and adnexa are obstacles for effective treatment of ocular GVHD. We hypothesized that topical cyclosporine A (CsA) pretreatment might be effective in preventing ocular GVHD. METHODS: In this prospective, randomized, comparative study, patients were randomly assigned to the topical CsA treatment (4 times daily in both eyes for a month before allogeneic HSCT and continued use of eye drops after transplantation) or control (no treatment) groups. Participants underwent thorough ophthalmic examination-including Ocular Surface Disease Index questionnaire survey, Schirmer test, tear break-up time (TBUT) evaluation, and corneal fluorescein staining-before and 1, 2, and 3 months after allogeneic HSCT. RESULTS: Fifty-eight participants completed the study. Among patients with baseline Schirmer values <10 mm and TBUT <5 s before allogenic HSCT, those in the topical CsA treatment group exhibited significantly better corresponding values after transplantation than patients in the control group. CONCLUSIONS: Topical CsA pretreatment might be beneficial in the early stage of DED and might prevent further inflammation and consequent irreversible fibrosis, especially in patients with preexisting DED components. PMID- 30289330 TI - Changes in Detected Anticoagulant Rodenticide Exposure in Barn Owls ( Tyto alba) in Kentucky, USA, in 2012-16. AB - Anticoagulant rodenticides (ARs) are widely used across North America to control rodent infestations but may cause direct mortality or nonlethal effects when secondarily consumed by raptors. Barn Owls ( Tyto alba) are at high risk for secondary consumption because they specialize in rodent prey and often live in human-made structures. We investigated the exposure of Barn Owls in Kentucky, US, to ARs and to dicoumarol, an anticoagulant compound naturally found in certain moldy forages. We tested the liver tissue of 48 Barn Owl carcasses collected during 2012-16. We confirmed exposure to one or more ARs in 33% of the birds examined and detected dicoumarol in 13% of the samples. Rodenticides detected included brodifacoum, coumachlor, and bromadiolone. The prevalence of detected exposure to brodifacoum for after-hatch-year birds (65%) was significantly ( P=0.012) higher than hatch-year birds (22%). Brodifacoum was the most commonly detected AR, found in 88% of AR-positive birds. The pesticide registration for this chemical in the US was canceled in 2015 for general consumer products, which likely resulted in a decreasing rate of detected exposure to brodifacoum during our study. We present these results as an example of secondary exposure rates during a period when a pesticide has been restricted and then removed from the consumer market. PMID- 30289331 TI - Survey of Arctic Alaskan Wildlife For Influenza A Antibodies: Limited Evidence For Exposure of Mammals. AB - Influenza A viruses (IAVs) are maintained in wild waterbirds and have the potential to infect a broad range of species, including wild mammals. The Arctic Coastal Plain of Alaska supports a diverse suite of species, including waterfowl that are common hosts of IAVs. Mammals co-occur with geese and other migratory waterbirds during the summer breeding season, providing a plausible mechanism for interclass transmission of IAVs. To estimate IAV seroprevalence and identify the subtypes to which geese, loons, Arctic foxes ( Vulpes lagopus), caribou ( Rangifer tarandus), and polar bears ( Ursus maritimus) are potentially exposed, we used a blocking enzyme-linked immunosorbent assay (bELISA) and a hemagglutination inhibition (HI) assay to screen for antibodies to IAVs in samples collected during spring and summer of 2012-16. Apparent IAV seroprevalence using the bELISA was 50.7% in geese (range by species: 46.1 52.8%), 9.2% in loons, (range by species: 3.4-20.0%), and 0.4% in Arctic foxes. We found no evidence for exposure to IAVs in polar bears or caribou by either assay. Among geese, we estimated detection probability from replicate bELISA analyses to be 0.92 and also found good concordance (>85%) between results from bELISA and HI assays, which identified antibodies reactive to H1, H6, and H9 subtype IAVs. In contrast, the HI assay detected antibodies in only one of seven loon samples that were positive by bELISA; that sample had low titers to both H4 and H5 IAV subtypes. Our results provide evidence that a relatively high proportion of waterbirds breeding on the Arctic Coastal Plain are exposed to IAVs, although it is unknown whether such exposure occurs locally or on staging or wintering grounds. In contrast, seroprevalence of IAVs in concomitant mammals is apparently low. PMID- 30289333 TI - 7th International Society for Physical Activity and Health Congress.

AB - BACKGROUND: Urological symptoms such as gross hematuria, lower and upper urinary tract symptoms, and bladder pain are common in and distressing for patients with advanced cancer. Although palliation of urological symptoms is important to improve the quality of life of cancer patients and their families and caregivers, clinical guidelines for managing urological symptoms in patients with cancer have not been published. METHODS: Following the formal guideline development process, the Japanese Society for Palliative Medicine (JSPM) developed comprehensive clinical guidelines for the management of urological symptoms in patients with cancer. RESULTS: This article summarizes the recommendations and their rationales and provides a short summary of the development process of the JSPM urological symptom management guidelines. We established five recommendations, all of which were based on the best available evidence and expert consensus. CONCLUSION: JSPM released the first edition of the "Clinical Guidelines for Urological Symptoms in Cancer Patients." Future clinical research and continuous guideline updates are required to improve the quality of managing urological symptoms in patients with cancer. PMID- 30289334 TI - Genetic Characterization of Canine Parvovirus 2 Detected in Wild Raccoon Dogs ( Nyctereutes procyonoides) in the Republic of Korea. AB - Canine parvovirus (CPV) was detected in three of 136 samples from dead raccoon dogs ( Nyctereutes procyonoides) in the Republic of Korea (South Korea) during 2016-17. By sequence and phylogenetic analysis of the complete VP2 gene, the strain belonged to CPV-2 and would be distinct from the previous reported CPV-2a and CPV-2b strains from Korean domestic dogs ( Canis lupus familiaris). The results indicated that the CPV strains from raccoon dogs and domestic dogs might be not circulated between wild and domestic carnivores in Korea. PMID- 30289335 TI - Activated kinase screening identifies the IKBKE oncogene as a positive regulator of autophagy. AB - : Macroautophagy/autophagy is one of the major responses to stress in eukaryotic cells and is implicated in several pathological conditions such as infections, neurodegenerative diseases and cancer. Interestingly, cancer cells take full advantage of autophagy both to support tumor growth in adverse microenvironments and to oppose damages induced by anti-neoplastic therapies. Importantly, different human oncogenes are able to modulate this survival mechanism to support the transformation process, ultimately leading to 'autophagy addiction'. Still, oncogenic signaling events, impinging on the control of autophagy, are poorly characterized, limiting our possibilities to take advantage of these mechanisms for therapeutic purposes. Here, we screened a library of activated kinases for their ability to stimulate autophagy. By this approach, we identified novel potential regulators of the autophagic process and, among them, the IKBKE oncogene. Specifically, we demonstrate that this oncoprotein is able to stimulate autophagy when overexpressed, an event frequently found in breast tumors, and that its activity is strictly required for breast cancer cells to support the autophagic process. Interestingly, different oncogenic pathways typically involved in breast cancer, namely ERBB2 and PI3K-AKT-MTOR, also rely on IKBKE to control this process. Ultimately, we show that IKBKE-dependent autophagy is necessary for breast cancer cell proliferation, suggesting an important supporting role for this oncogene and autophagy in these tumors.

AB - : During development of colon cancer, Protein Kinase Cs (PKCs) are involved in regulation of many genes controlling several cellular mechanisms. Here, we examined the changes in cell adhesion molecules and PKCs for colorectal cancer progression. We identified that PKCs affected expression of EpCAM, claudins, tetraspanins. Treatment with low concentrations of PKC inhibitors resulted in decreased cell viability. In addition, immunoblotting and qRT-PCR analysis showed that apoptosis was inhibited while autophagy was induced by PKC inhibition in colon cancer cells. Furthermore, we observed decreased levels of intracellular Reactive Oxygen Species (ROS), lipid peroxidation and protein carbonyl, confirming the ROS-induced apoptosis. Taken together, our results reveal that PKC signalling modulates not only cell adhesion dynamics but also cell death-related mechanisms.

PMID- 30289337 TI - Metagenomic Next-Generation Sequencing Reveals Miamiensis avidus (Ciliophora: Scuticociliatida) In the 2017 Epizootic of Leopard Sharks ( Triakis semifasciata) In San Francisco Bay, California, USA. AB - During March to August of 2017, hundreds of leopard sharks ( Triakis semifasciata) stranded and died on the shores of San Francisco Bay, California, USA. Similar mass stranding events occurred in 1967 and 2011, but analysis of those epizootics was incomplete, and no etiology was confirmed. Our investigation of the 2017 epizootic revealed severe meningoencephalitis in stranded sharks, raising suspicion for infection. We pursued a strategy for unbiased pathogen detection using metagenomic next-generation sequencing followed by orthogonal validation and further screening. We showed that the ciliated protozoan pathogen, Miamiensis avidus, was present in the central nervous system of leopard ( n=12) and other shark species ( n=2) that stranded in San Francisco Bay but was absent in leopard sharks caught elsewhere. This ciliated protozoan has been implicated in devastating outbreaks in teleost marine fish but not in wild elasmobranchs. Our results highlight the benefits of adopting unbiased metagenomic sequencing in the study of wildlife health and disease. PMID- 30289338 TI - Isolation, Not Loneliness or Cynical Hostility, Predicts Cognitive Decline in Older Americans. AB - OBJECTIVE: To jointly examine isolation, loneliness, and cynical hostility as risk factors for cognitive decline in older adults. METHOD: Data came from the 2006 to 2012 waves of the Health and Retirement Study (HRS), a longitudinal study of U.S. older adults (age ? 65 years, n = 6,654). Measures included frequency of contact with social network (objective isolation), the Hughes Loneliness Scale (loneliness), a modified version of the Cook-Medley Hostility Inventory (cynical hostility), and a modified version of the Telephone Interview for Cognitive Status (cognitive function). Multilevel modeling (random slope + intercept) was used to examine the association between these factors and trajectories of cognitive function. RESULTS AND DISCUSSION: After controlling for demographic characteristics, self-reported health, and functional limitations, loneliness (beta = -.34, 95% confidence interval [CI] = [-0.56, -0.11), and cynical hostility (beta = -.14, 95% CI = [-0.24, -0.04) correlated with lower cognitive function, but none predicted change in cognitive function. Objective social isolation was associated with lower cognitive function (beta = -.27, 95% CI = [ 0.41, -0.12]) and steeper decline in cognitive function (beta = -.09, 95% CI = [ 0.16, -0.01]). PMID- 30289339 TI - A Determinants of Health Conceptual Model for Fish and Wildlife Health. AB - Our objectives were to establish if the determinant of health model used in the fields of human population and public health could be adapted to wildlife health; if it was applicable to more than one species; and if it reflected how fish and wildlife managers conceptualized health in practice. A conceptual model was developed using a scoping review on fish and wildlife health and resilience coupled with a participatory process with experts on barren ground caribou ( Rangifer tarandus groenlandicus) and sockeye salmon ( Oncorhynchus nerka) health. Both the literature and experts supported the concept of wildlife health as a cumulative effect involving multiple factors that extend beyond the disease and pathogen focus of many wildlife health studies and legislation. Seven themes were associated with fish and wildlife health: 1) the biologic endowment of the individual and population; 2) the animal's social environment; 3) the quality and abundance of the animal's needs for daily living; 4) the abiotic environment in which the animal lives; 6) sources of direct mortality; and 7) changing human expectations. These themes were shared between salmon and caribou and conformed to expert perceptions of health. Determinants of health used in human public health are used for planning, development of policy, and guiding of research. The model we produced may also have use as a wildlife health planning tool to help managers identify health protection priorities and to promote actions across the determinants of health. PMID- 30289340 TI - Density override in treatment planning to mitigate the dosimetric effect induced by gastrointestinal gas in esophageal cancer radiation therapy. AB - PURPOSE: To investigate the dosimetric effect of variable gas volume in esophageal cancer radiation therapy (RT) and whether a density override (DO) in treatment planning can effectively mitigate this dosimetric effect. MATERIAL AND METHODS: Nine patients with gastrointestinal gas pockets in the planning computed tomography (pCT) were retrospectively included. Per patient, the intensity modulated RT (IMRT) and volumetric-modulated arc therapy (VMAT) plans associated with no DO, DO = 0.5, and DO = 1 in the gas pockets were made. Initial and follow up gas volumes were assessed from the pCTs and cone-beam CTs (CBCTs), respectively. Fractional CTs were created based on the pCT and CBCTs to calculate the fractional doses using all six plans. We then investigated for all six plans the correlation between the gas volume difference (relative to initial gas volume) and the dose difference (relative to planned dose). We also calculated and compared the accumulated dose by summing the fractional doses using two strategies: single-plan strategy (i.e. using each of the six plans separately) and plan-selection strategy (i.e. selecting one of the three plans depending on the fractional gas volume for IMRT and VMAT planning separately). RESULTS: The dose difference was approximately linearly correlated to the gas volume difference. Underdoses of >3.5% and overdoses of >7% were found for gas volume decreases >160 mL/330 mL and increases >260 mL/370 mL for IMRT/VMAT planning, respectively. Moreover, for most patients, the single-plan strategy with the use of DO = 0.5 resulted in neither undesired underdose nor much overdose. The plan selection strategy, however, can always ensure sufficient target coverage and minimize high dose regions to the most extent. CONCLUSIONS: The variation in gas volume during the treatment course can result in clinically undesired underdose or overdose. The DO-based plan-selection strategy can effectively mitigate the gas-induced underdose and minimize the overdose for esophageal cancer RT. PMID- 30289341 TI - Beyond diagnosis: the relevance of social interactions for participation in inclusive preschool settings. AB - PURPOSE: This study aims to explore the role of three specific factors within the child-environment interaction process - engagement, independence and social interactions - in influencing development and learning of children with disabilities in inclusive preschool settings. The main question is whether children can be categorised in homogenous groups based on engagement, independence and social interactions (proximal variables within a biopsychosocial framework of human development). The study also examined whether children with the same diagnosis would group together or separately, when trying to identify clusters of engagement, independence and social interactions, and additionally whether such clusters vary as a function of individual child characteristics, and/or as a function of structural and process characteristics of preschool environment. METHODS: Data was taken from an intervention study conducted in mainstream preschools in Portugal. A person-centered cluster analysis was conducted to explore group membership of children with various diagnoses, based on their engagement, independence and social interaction profiles. RESULTS: Results show that children clustered based on similarity of engagement, independence and social interaction patterns, rather than on diagnosis. Besides, it was found that quality of peer interaction was the only predictor of cluster membership. CONCLUSION: These findings support the argument that participation profiles may be more informative for intervention purposes than diagnostic categories, and that preschool process quality, namely peer interaction, is crucial for children's participation.

AB - The epidemiological tracking of a bacterial outbreak may be jeopardized by the presence of multiple pathogenic strains in one patient. Nevertheless, this fact is not considered in most of the epidemiological studies and only one colony per patient is sequenced. On the other hand, the routine whole genome sequencing of many isolates from each patient would be costly and unnecessary, because the number of strains in a patient is never known a priori. In addition, the result would be biased by microbial culture conditions. Herein we propose an approach for detecting mixed-strain infection, providing C. difficile infection as an example. The cells of the target pathogenic species are collected from the bacterial suspension by the fluorescence activated cell sorting (FACS) and a shallow genome sequencing is performed. A modified sequencing library preparation protocol for low-input DNA samples can be used for low prevalence gut pathogens (< 0.1% of the total microbiome). This FACS-seq approach reduces diagnostics time (no culture is needed) and may promote discoveries of novel strains. Methodological details, possible issues and future directions for the sequencing of these natural pan-genomes are herein discussed.

AB - BACKGROUND: Total-laparoscopic intragastric surgery (T-LIGS) has gradually been accepted for the treatment of endogenous gastric submucosal tumors. However, it is difficult to perform T-LIGS when the tumor is located at the esophagogastric junction (cardia endogenous gastric submucosal tumor [CEGSMT]) without special laparoscopic instruments that are not available in most developing countries. We have successfully treated 12 cases of CEGSMTs using conventional laparoscopic instruments and achieved acceptable outcomes. This study was conducted to evaluate the surgical techniques for CEGSMT management. METHODS: A retrospective analysis was conducted involving all the CEGSMT patients who were treated with T LIGS in the General Surgery Department of Guangdong General Hospital from August 2014 to June 2016. RESULTS: There were 12 patients successfully treated with T LIGS. The surgical time ranged from 56 to 108 minutes, and the blood loss was 5 70 mL. The distance to the tumor from the dentate line was 12-24 mm, and the tumor diameter was 17-28 mm. The tumor margins were 9-15 mm, and the eating time was 2-4 days. The drainage tube indwelling time was 2-4 days, and the discharge time was 4-6 days. The follow-up exams revealed no recurrences, dysphagia, acid reflux, or other digestive symptoms. CONCLUSIONS: It is safe and feasible to perform T-LIGS using conventional laparoscopic instruments to treat CEGSMTs. We suggest that T-LIGS can be performed for endogenous mucosal tumors within 3 cm from the cardiac dentate line and less than 3 cm in size. PMID- 30289345 TI - The authors reply.

AB - INTRODUCTION: Although laparoendoscopic single-site adrenalectomy (LESS-A) is feasible, it is still considered as a challenging procedure because of technical limitations. Making an optimal retraction is one of major obstacles in LESS-A, and it sometimes requires additional ports or needlescopic devices. Internal organ retractor (IOR) is a novel retraction device that is applied intracorporeally without additional port. In this study, we investigated the clinical usefulness of IOR in LESS-A. MATERIALS AND METHODS: Medical records of 73 consecutive patients who underwent LESS-A from March 2009 to December 2014 were reviewed. Twenty-two patients underwent LESS-A with IOR and 51 patients without IOR. RESULTS: Mean age, body mass index, tumor size, operation time, estimated blood loss, and hospital stay were not significantly different between two groups. In IOR group, median number of applied IOR was 2.0 (1.0-3.0) per single operation. Mean time for application and removal was 80.0 and 46.5 seconds for a single IOR, respectively. There were no complications related to the IOR. In without IOR group, there were nine cases that needed needlescopic trocars, six cases that needed 5 mm or larger trocars, and one case that was converted to hand assisted laparoscopy. However, we did not use any needlescopic instrument or additional trocar in IOR group. There was no case of open conversion in both groups. CONCLUSION: LESS-A could be done effectively and safely using IOR. IOR system maintained optimal retraction throughout the operation. Its application and removal are intuitive and take only a few minutes. We think IOR system is an attractive retraction method in LESS-A.

PMID- 30289350 TI - Normothermic ex vivo liver perfusion: platform for liver graft assessment and therapeutic modification. AB - Liver transplantation as a treatment for end stage liver failure remains limited in the United States by the number and quality of donor allografts. Static cold storage, the current standard of care for organ storage prior to transplantation, offers no method for assessment or therapeutic modification. Cold ischemia and its attendant hypoxia deplete cellular adenosine triphosphate (ATP) stores, promote cellular damage, and degrade overall organ quality. Normothermic ex vivo liver perfusion (NEVLP) offers the potential for assessment of allograft function and restoration of intracellular energy stores prior to transplantation. A completed phase III randomized trial demonstrated livers undergoing NEVLP prior to transplantation demonstrate superior early graft function and less early graft dysfunction. NEVLP offers a platform for modification of the allograft via the application of defatting or therapeutic cocktails, missense RNA technology, or gene editing modalities. The wide versatility of NEVLP appears to be a promising tool to expand the current pool of transplantable liver allografts. PMID- 30289349 TI - Physician Choice of Hypothyroidism Therapy: Influence of Patient Characteristics. AB - BACKGROUND: Most endocrinologists encounter patients who are dissatisfied with their current hypothyroidism therapy and request combination therapy with either liothyronine (LT3) or thyroid extract. METHODS: A survey of American Thyroid Association members was conducted in 2017. Respondents were presented with 13 scenarios describing patients with hypothyroidism and were asked to choose among six therapeutic options. The index patient was satisfied taking levothyroxine (LT4) therapy. Twelve variations introduced parameters that potentially provide reasons for considering combination therapy (presence of symptoms, low serum triiodothyronine concentration, documentation of deiodinase polymorphisms). Therapeutic options included (i) continuing LT4, (ii) increasing LT4, (iii) adding LT3 to a reduced LT4 dose, (iv) adding LT3 to the current LT4 dose, (v) replacing LT4 with thyroid extract, and (vi) replacing LT4 with LT3. Repeated measures logistic regression analysis was performed to examine both the prescribing of LT4 (options i and ii) versus all other therapies and the choice of continuing LT4 (option i) versus either increasing LT4 (option ii), adding LT3 (options iii and iv), or replacing LT4 with thyroid extract or LT3 (options v and vi). RESULTS: Of the 389 survey respondents, 363 physicians prescribed therapy for hypothyroidism. For the index patient, 98% of physicians continued current LT4 therapy. However, as the patient scenario incorporated other patient characteristics, physicians opted to increase LT4 dose or prescribe other therapies. The tendency to prescribe alternative therapies was powerfully increased by patient symptoms (odds ratio = 25.6 [confidence interval 9-73], p < 0.0001). Older age and the presence of a comorbidity reduced the likelihood that an alternative therapy was prescribed (p = 0.0002 and <0.0001, respectively). All other characteristics, except athyreotic status, patient sex, and body mass index, significantly increased the likelihood that alternative therapies would be prescribed in multivariate analyses (p < 0.0001). CONCLUSIONS: Even with the acknowledged limitations of survey methodology, this analysis appears to show a marked increase in the willingness of physicians to prescribe combination therapy in specific circumstances. If current prescribing patterns do incorporate the use of therapies other than LT4, there is a critical need for more research into the benefits and risks of these therapies.

AB - OBJECTIVE: The feasibility and perspective of pyloric chisel were discussed through the comparison of pyloric chisel and knife in the treatment of hypertrophic pyloric stenosis (HPS) in single-site umbilical laparoscopic pyloromyotomy (SSULP). METHODS: Fifty-eight cases of HPS treated in our hospital from February 2011 to March 2016 were retrospectively analyzed, in which 30 patients underwent pyloric chisel (Pyloric chisel Group) and 28 patients underwent knife (Knife Group). Operative time, estimated blood loss, and complications between the two groups were analyzed. RESULTS: The operative time was shorter in Pyloric chisel Group than Knife Group (P < .05). The estimated blood loss was lower in Pyloric chisel Group than Knife Group (P < .05). The complication was less in Pyloric chisel Group than Knife Group (P < .05). There were 2 cases of mucosal perforations requiring conversions to open in Knife Group. Five cases of serous tearing occurred in the Knife Group. There was 1 case of serous tearing in the Pyloric chisel Group. All patients were followed up for 3 months, and there was no distinct scar in the umbilical. CONCLUSIONS: Patients were satisfied with no distinct scars in abdominal wall by pyloric chisel or knife to treat HPS in SSULP, but pyloric chisel is more effective and safer.

AB - Laboratory investigations of the pathogenesis of Pseudogymnoascus destructans, the fungal causal agent of bat White Nose Syndrome (WNS), presents unique challenges due to its growth requirements (4 degrees -15 degrees C) and a lack of infectivity in the current disease models. Pseudogymnoascus pannorum is the nearest fungal relative of P. destructans with wider psychrophilic - physiological growth range, and ability to cause rare skin infections in humans. Our broad objectives are to create the molecular toolkit for comparative study of P. destructans and P. pannorum pathogenesis. Towards these goals, we report the successful development of an invertebrate model in the greater wax moth Galleria mellonella. Both P. destructans and P. pannorum caused fatal disease in G. mellonella and elicited immune responses and histopathological changes consistent with the experimental disease. PMID- 30289354 TI - Alpha ketoglutarate levels, regulated by p53 and OGDH, determine autophagy and cell fate/apoptosis in response to Nutlin-3a. AB - Activated p53 can promote apoptosis or cell cycle arrest. Differences in energy metabolism can influence cell fate in response to activated p53. Nutlin-3a is a preclinical drug and small molecule activator of p53. Alpha-ketoglutarate (alphaKG) levels were reduced in cells sensitive to Nutlin-3a-induced apoptosis and increased in cells resistant to this apoptosis. Add-back of a cell-permeable alphaKG analog (DMKG) rescued cells from apoptosis in response to Nutlin-3a. OGDH is a component of the alphaKGDH complex that converts alphaKG to succinate. OGDH knockdown increased endogenous alphaKG levels and also rescued cells from Nutlin 3a-induced apoptosis. We previously showed reduced autophagy and ATG gene expression contributes to Nutlin-3a-induced apoptosis. DMKG and OGDH knockdown restored autophagy and ATG gene expression in Nutlin-3a-treated cells. These studies indicate alphaKG levels, regulated by p53 and OGDH, determine autophagy and apoptosis in response to Nutlin-3a. PMID- 30289356 TI - Understanding your body matters: Effects of an entertainment-education serial radio drama on fertility awareness in Rwanda. AB - Given widespread misunderstanding of pregnancy risk, awareness of one's fertility has the potential to influence sexual and reproductive health behaviors. This mixed-methods study examined the impact of a serial radio drama in Rwanda, Impano n'Impamba, on fertility awareness and other factors related to family planning uptake by comparing listeners and non-listeners in a nationally representative household survey (n = 1477) and analyzing in-depth interviews with 32 listeners. Listeners had higher fertility awareness than non-listeners for key concepts, including the menstrual cycle, onset of fertility, and postpartum pregnancy risk. Qualitative interviews suggest discussion groups provided an invaluable opportunity to ask questions to a knowledgeable facilitator and clarify the fertility awareness information. No significant differences in modern family planning use or intention to use were found between listeners and non-listeners, but listeners reported greater supportive norms, self-efficacy, and discussion of family planning. Qualitative interviews suggest that increased discussion about family planning occurred because the drama emboldened people to talk about uncomfortable and taboo topics. Post-broadcast, listeners of Impano n'Impamba had greater fertility awareness then non-listeners and were more likely to experience intermediate outcomes related to family planning such as perception of positive family planning norms, a feeling of self-efficacy, and increased communication with others related to family planning. The study provides lessons for future interventions with the aim of increasing fertility awareness to improve sexual and reproductive health. PMID- 30289357 TI - Combining Two Outcome Frames to Promote Support for Obesity-Related Policies. AB - Guided by construal level theory (CLT), this study investigates the interplay between two framing approaches that address outcomes of obesity-related policies. A randomized experiment (N = 299) was conducted with a 2 (gain- vs. loss-frame) X 2 (societal- vs. individual-frame) between-participants design. Consistent with CLT, frame combinations with consistent construal levels were more persuasive. Compared to a societal-loss frame, a societal-gain frame was perceived as a stronger argument, which in turn increased policy support. Participants were also more likely to engage in healthier diets and physical activity when messages highlighted societal-gain rather than societal-loss. This study offers important insights for combining multiple framing approaches in a persuasive message to improve policy support as well as individual health decisions. PMID- 30289355 TI - Infection risk with alemtuzumab decreases over time: pooled analysis of 6-year data from the CAMMS223, CARE-MS I, and CARE-MS II studies and the CAMMS03409 extension study. AB - BACKGROUND: Reduced MS disease activity with alemtuzumab versus subcutaneous interferon beta-1a (SC IFNB-1a) in core phase 2/3 studies was accompanied by increased incidence of infections that were mainly nonserious and responsive to treatment. Alemtuzumab efficacy was durable over 6 years. OBJECTIVE: To evaluate infections over 6 years in alemtuzumab-treated patients. METHODS: Three randomized trials (CAMMS223, Comparison of Alemtuzumab and Rebif Efficacy in Multiple Sclerosis (CARE-MS) I, and CARE-MS II) compared two courses of alemtuzumab 12 mg with SC IFNB-1a 44 MUg in patients with active relapsing remitting MS. An extension study (CAMMS03409) provided further evaluation and as needed alemtuzumab retreatment. RESULTS: Infections occurred more frequently with alemtuzumab 12 mg than SC IFNB-1a during Years 1 (58.7% vs 41.3%) and 2 (52.6% vs 37.7%), but declined for alemtuzumab-treated patients in Years 3 (46.6%), 4 (42.8%), 5 (40.9%), and 6 (38.1%). Serious infections were uncommon (1.0%-1.9% per year). Infections were predominantly (>95%) mild to moderate and included upper respiratory tract infections, urinary tract infections, and mucocutaneous herpetic infections. Prophylactic acyclovir reduced herpetic infections. Lymphocyte counts after alemtuzumab therapy did not predict infection risk. CONCLUSION: Infections with alemtuzumab were mostly mild to moderate and decreased over time, consistent with preservation of components of protective immunity. PMID- 30289358 TI - Swimmers' Compliance to Training as a Function of Observation: A Pilot Study. AB - : Adherence to prescribed training intensity (i.e., swim speed) has been conveyed as a key parameter regarding improvements in seasonal performance. Evidence has also suggested swimmers have difficulty complying with coach-prescribed training. How this compliance is affected by a coaching presence and oversight has yet to be examined. PURPOSE: The purpose of this study was to determine swimmers' compliance to prescribed training intensity during 3 observational conditions using activity monitors. METHOD: Individualized prediction equations were created via linear regression analyses for intensity using arm-stroke and leg-kick activity counts during a series of seven 91.4-m swim bouts in a group of 17 collegiate swimmers. Equations were used to calculate intensity performed during a standardized training session during which only the observational condition varied (e.g., a coach present on deck, no coach present on deck, and an appointed observer in addition to the coach present on deck). Compliance was calculated from the difference between prescribed training intensity and performed swim intensity. Comparisons were made between observed coaching conditions for compliance using a repeated-measures analysis of variance. RESULTS: Swimmers' compliance to prescribed training intensity during the no-coach condition was less compared with the other conditions, including (a) when a coach was present and (b) when a coach and an additional observer were present (eta2 = .58). CONCLUSION: The presence of a coach or lack thereof appeared to be critical in terms of swimmers' compliance to prescribed training intensity. Additional observation by nonsupervisory individuals appeared to have no significant effect on swimmers' compliance. PMID- 30289359 TI - The War Within: Diaries From the Siege of Leningrad.

AB - PURPOSE: To investigate the effect of generalization of engagement in parkour from physical education (PE) to organized and supervised recess on voluntary participation and moderate-to-vigorous physical activity (MVPA). METHOD: Children received a 6-day parkour unit in PE and every two lessons they could voluntarily participate in 20-min parkour recess. Fourteen elementary school classes constituting 281 children (8-10 years old) and 16 PE teachers were randomized to either three supervised or three organized parkour recess sessions. During supervised recess, PE teachers supervised to ensure safety, and children could play freely on the parkour landscape. During organized recess, PE teachers provided instructional tasks as well as supervision for safety on the parkour landscape. The parkour landscape in the gymnasium was identical in both recess conditions and similar to previous parkour landscape in PE. Participation and MVPA were measured using systematic observation. RESULTS: Significantly more children from organized compared to supervised recess participated in all three sessions (60% vs. 43%, p = .008, V = .16). Children showed significantly less sedentary behavior (24% vs. 30%, p = .013, eta2 = .063) and more MVPA (76% vs. 70%, p = .012, eta2 = .066) during organized compared to supervised recess. The proportion of total MVPA spent doing parkour was significantly higher in organized compared to supervised recess for low- (36% vs. 24%, p = .005, eta2 = .082) and high-skilled children (33% vs. 26%, p = .034, eta2 = .048). CONCLUSION: Generalization of engagement in parkour was higher in organized compared to supervised recess. PMID- 30289361 TI - Richmond Barthe: Black Homoeroticism and the Raptures of the Hermaphroditic Body. AB - African American sculptor Richmond Barthe (1901-1989) conjoined issues of sexuality and race in works that foreground the aesthetic worth of Black bodies. While exposing Western figuration practices that exclude Black people from artistic visibility, Barthe also targeted the African American distaste for the explicit treatment of nudity. Barthe's androgynous sculptures have by now become the trademark of his art, but Barthesian scholarship still neglects the significance of a small group of statues, which de-emphasize the aura of same-sex desire, in order to explore the intricacies of corporeal ambisexuality. In view of his homoerotic depictions and the presence of the hermaphrodite at the core of his disruption of the sexual dichotomy, the frequent assumption that Barthe remained "closeted all his life" does not stand critical scrutiny. Instead of taking refuge in the sexual closet, Barthe debunked the man/woman binary as the foremost epistemic construct that prompts the societal need for sexual self misrepresentations. PMID- 30289362 TI - Second-generation Western Muslims: A qualitative analysis of multiple social identities. AB - The relationships between social identities are important when discussing the national and religious identities of Muslims in Western contexts. This study explored the identity narratives of second-generation Muslim young adults to consider the relevance of bicultural identity and acculturation theories commonly employed in research with this group. The sample comprised 20 Muslim young adults of diverse ethnicities and backgrounds from Montreal, Berlin, and Copenhagen who participated in semi-structured interviews that explored how they negotiate their social identities in light of their unique life course trajectories. This article focuses on two major themes underlying second-generation identity development: the importance of personal experience in the development of social identities; and the enmeshment of multiple social identities. We then discuss the results of our findings in light of the complex nature of social identity, group membership, and political categorization. PMID- 30289363 TI - Disconnectomics: Stroke-related disconnection and dysfunction in distributed brain networks. AB - Modern clinical neuroscience was built on observations of how localized damage caused specific functional, cognitive and behavioral deficits. Stroke neurology was a cornerstone of understanding this functional specialization in the brain. But most lesion-symptom mapping provides little prognostic value above clinical observations. Stroke topography remains a poor indicator of long-term outcome, and with stroke a major risk factor for dementia, there is strong incentive to find markers of predictive value. There is now growing recognition that the damage caused by stroke does not occur in isolation but is embedded within a complex, highly interconnected, organized and dynamic system: the connectome. Early theories of the widespread effect of focal lesions are resurfacing, buoyed by sophisticated new methods and large-scale data sets. As with all emerging methods and technologies, there may be healthy skepticism as to the appropriateness of the method to the population under investigation or doubt that connectivity-derived metrics will ever be clinically translatable. While we acknowledge that there remain significant technical challenges to overcome, we argue that the methods provide real potential to illuminate our understanding of the widespread effects and clinical syndromes that can arise from diverse focal damage. PMID- 30289364 TI - Profiles of Trauma in Primary and Permanent Teeth of Children and Adolescents. AB - This retrospective study aimed to evaluate the dental trauma profile in primary and permanent teeth from patients between 0 and 15 years old who attended the Faculty of Dentistry of the Federal University of Rio de Janeiro. Data regarding gender, age, trauma classification, tooth type, and affected tissues were obtained from dental records. The data were analyzed descriptively and by the chi2 test (p < 0.05). Data associated with 333 traumatized teeth (70% primary and 30% permanent teeth) were included. The mean ages of children with affected primary and permanent teeth were 3.35 +/- 2.02 and 9.09 +/- 2.43 years, respectively. Males presented more permanent teeth with trauma (64.4%) than primary ones (55.6%; p = 0.085). The upper central incisors, both primary (68.9%) and permanent (69.4%), were the teeth most commonly affected. Primary teeth showed a higher frequency (p < 0.001) of supportive tissue trauma (73.3%) and lower frequency (p = 0.001) of hard tissue trauma (40.7%) than those in permanent ones (51.5% and 60.6%, respectively). The most frequent trauma in the supportive tissue was subluxation (27.2%) and permanent lateral luxation (42.0%). In the hard tissues, permanent teeth presented a higher prevalence of trauma than primary ones (p = 0.001), however this difference was not statistical significant when each type of fracture injury was evaluated individually (p > 0.005). With affected primary teeth, there was a greater frequency of trauma in the gingival mucosa (31.0%; p = 0.022); in the permanent ones, traumatic lesions in the chin region were the most prevalent (20.8%; p = 0.009). Trauma was recurrent in 26.3% of primary teeth and in 20.2% permanent teeth. Therefore, primary and permanent teeth showed distinct trauma profiles, suggesting that distinct preventive and therapeutic approaches are needed for these two groups. PMID- 30289365 TI - Clinical and Radiographic Evaluation of Formocresol and Chloramphenicol, Tetracycline and Zinc Oxide-Eugenol Antibiotic Paste in Primary Teeth Pulpotomies: 24 month follow up. AB - OBJECTIVE: The purpose of the present study was to evaluate clinically and radiographically the effectiveness of formocresol and the antibiotic paste CTZ (chloramphenicol, tetracycline and zinc oxide-eugenol) in primary teeth pulpotomies, during a 6, 12 and 24 month period. STUDY DESIGN: A total of 80 pulpotomies were performed in 58 patients between three and six years of age. The patients were selected and assigned to two groups: Group I Formocresol (FC, n=40), Group II chloramphenicol-tetracycline-zinc oxide eugenol (CTZ, n=40). The teeth were restored with glass ionomer and pre-formed stainless steel crowns. The treated teeth were evaluated clinically and radiographically at 6, 12 and 24 months. RESULTS: After 24 months of follow up a 100% and 94.3% clinical success was obtained, in the CTZ and formocresol groups respectively (x2= 0.450, p>0.05). The radiographic success was of 97.4% and 94.3% respectively (x2= 0.920, p>0.05). CONCLUSION: The performance of the antibiotic paste CTZ was superior to formocresol. No statistically significant differences were observed between the treatment groups either clinically or radiographically. More randomized clinical trials should be performed before it can be indicated safely. PMID- 30289366 TI - Salivary Factors Related to Caries in Children with Autism. AB - : Many predisposing factors to caries are present in autism, however, it is unlikely that autistic patients exhibit higher caries indexes than the rest of the population. OBJECTIVE: To evaluate salivary factors related to caries in autistic patients. STUDY DESIGN: 34 autistics and 34 controls aged between 4-13 years old were included. Decayed, missing, and filled teeth (DMFT) index and oral hygiene simplified index (IHO-S) were assessed, as well as, pH, total proteins, phosphate, calcium and IgA in saliva. All data were analyzed by chi2 and Student t tests for independent samples. P values<0.05 were considered statistically significant. RESULTS: Autistic patients showed less caries than controls (p<=0.001), DMFT was 1+/-1 and 3+/-2 respectively (p<=0.001). In relation to IHO S, values increased (p=0.008) in autistic patients (2.25+/-0.78) compared to controls (1.79+/-0.59), however Salivary ph means were similar (7.20+/-0.48 and 7.27+/-0.34 respectively). Decreased calcium levels (p=0.013) were observed in autistics (0.621+/-0.35 mmol/L) compared to controls (0.89+/-0.51 mmol/L), but phosphate levels were similar (6.17+/-4.22 M, 5.51+/-4.86 M respectively). When total proteins of saliva were assessed, autistics showed a slight increment (2.65+/-1.81 mg/mL) compared to controls (2.24+/-1.27 mg/mL) and zymography showed a higher proteolytic activity in autistic children. Finally, IgA concentration reached 116.55+/-90.97 MUg/mL in autistics and 161.61 +/- 193.37MUg/mL (p=0.527) in the control group. CONCLUSIONS: Even though patients with autism exhibited a poorer oral hygiene, caries indexes were lower, calcium levels in saliva were found to be lesser and phosphate levels higher. PMID- 30289367 TI - Posterior Available Space for Uprighting Horizontally Impacted Mandibular Second Molars Using Orthodontic Microimplant Anchorage. AB - Treatment of horizontally and deeply impacted mandibular molars is challenging for both orthodontists and oral surgeons because of the limited access and anchorage control. We report on two patients who had horizontally and mesially impacted mandibular second molars (MM2s). Both patients were treated by a surgical orthodontic approach, and the crowns of the impacted teeth were brought into the arches by closed forced eruption. Mesially impacted MM2s were uprighted with orthodontic microimplants, inserted in the retromolar area, and then moved into their ideal position. The first patient was in an active growing stage, while the second patient was beyond the active growing stage. Therefore posterior available space (PAS) should be analyzed before treatment of impacted MM2s to prevent periodontal problems after uprighting of impacted teeth. If PAS is not enough for uprighting impacted MM2s, alternative treatment should be considered based on the stage of growth. PMID- 30289368 TI - Fluoride Intake of Infants from Formula. AB - OBJECTIVE: This study aimed to assess fluoride intake in infants from formula reconstituted with water, with fluorosis risk in mind. STUDY DESIGN: Data on water source, formula brand/type, volume of formula consumption and infant weight were collected for infants at two-, four-, six-, nine- and twelve-month pediatrician well child visits. Identified formula brands and water types were reconstituted and analyzed for fluoride concentration. Patient body mass and volume consumed/day were used to estimate fluoride intake from reconstituted formula. Descriptive statistics, one-way analysis of variance and chi-square tests were utilized. RESULTS: All infants consumed formula reconstituted with minimally fluoridated water (0.0- 0.3 ppm). 4.4% of infants exceeded the recommended upper limit (UL) of 0.1mg/kg/day. Although mean daily fluoride consumption significantly differed among all groups, the proportion of infants at each visit milestone that exceeded daily fluoride intake of 0.1mg/kg/day was not statistically significantly different (p>0.05) for any age group. Predicted values calculated with optimally fluoridated water (0.7ppm) resulted in 36.8% of infants exceeding the UL. CONCLUSIONS: Optimally fluoridated water may increase fluorosis risk for patients younger than six months. Future investigation should include multiple sites and multi-year follow-up to assess actual fluorosis incidence. PMID- 30289369 TI - Titanium Dioxide Nanoparticles and Cetylpyridinium Chloride Enriched Glass Ionomer Restorative Cement: A Comparative Study Assessing Compressive Strength and Antibacterial Activity. AB - OBJECTIVE: To evaluate the addition of titanium dioxide (TiO2) nanoparticles and cetylpyridinium chloride (CPC) on the compressive strength and antibacterial activity of conventional glass-ionomer cement (GIC). STUDY DESIGN: TiO2 nanoparticles enriched GIC was prepared by adding 3% TiO2 nanoparticles (w/w) into the powder component of conventional GIC. CPC containing GIC was developed by incorporating 1% CPC (w/w) into conventional GIC powder. Samples were segregated into three groups: GIC with 3% TiO2 nanoparticles, GIC with 1% CPC and unmodified conventional GIC. Compressive strength was assessed using the universal testing machine on cylindrical specimens made from each material. Antibacterial activity was assessed by measuring inhibition zones on Mitis Salivarius Bacitracin (MSB) agar inoculated with pure strain of Streptococcus mutans (S. mutans). RESULTS: GIC containing TiO2 nanoparticles exhibited significantly greater compressive strength as compared with CPC and conventional GIC groups (P < 0.01). However, there was no significant difference between the compressive strengths of CPC and conventional GIC group (P >0.05). Antibacterial activity was significantly greater for TiO2 group than conventional GIC (P <0.05). CPC increased the antibacterial activity of conventional GIC, though not significantly. CONCLUSION: The addition of 3% TiO2 nanoparticles improves the compressive strength of GIC as well as its antibacterial activity against S. mutans. PMID- 30289370 TI - Oral Manifestations of Autoimmune Neutropenia: A Case Report. AB - Autoimmune neutropenia is a self-limiting condition characterized by the presence of granulocyte-specific autoantibodies. This case report describes a 2-year-old female who presented to the Department of Pediatric Dentistry with a history of oral ulceration, complicated by high temperature, gingival hypertrophy and gingival hemorrhage. These symptoms had precipitated an admission to a district general hospital and diagnosis of viral tonsillitis. The severity of the presentation to the Pediatric Dental Department prompted a review of recent discharge blood investigations, which revealed a neutrophil count of 0.07*109/L(1.0-8.5 *109/L) indicating severe neutropenia. Urgent referral to Pediatric Hematology resulted in same-day admission and a diagnosis of autoimmune neutropenia was established. The patient was managed with chlorhexidine mouthwash, prophylactic antimicrobial and antifungal medication and granulocyte colony stimulating factor (G-CSF). Neutropenia may present with features exclusive to the oral cavity. Recognition of atypical presentations such as oral ulceration with associated systemic illness may assist in early diagnosis.

AB - OBJECTIVE: To compare postoperative pain among children who received an oral dose of paracetamol, ibuprofen or a placebo, prior to tooth extractions. STUDY DESIGN: Thirty minutes prior to dental treatment, children received a liquid dosage, fruit flavored and orange colored, of paracetamol, ibuprofen, or a placebo. Data accessed included children's dental history, their behavior, and their feeling of pain or anxiety according to Wong-Baker FACES: before treatment, following local anesthesia, and following treatment. Parents were interviewed by telephone regarding their children's need for a postoperative analgesia (paracetamol or ibuprofen), and their feeling of pain at four and 24 hours posttreatment. RESULTS: Parents reported administering paracetamol or nurofen following the dental procedure to 9/43 (21%), 2/33 (6%) and 12/29 (41%) of the children in the preemptive paracetamol, ibuprofen, and placebo groups, respectively. For the 3 groups, mean pain assessment were similar: around the middle of the Wong-Baker FACES scale at baseline, slightly higher following local anesthesia, and low (pain-free) at four and 24 hours postoperative. CONCLUSION: Children who received paracetamol or ibuprofen prior to tooth extractions were less likely to need an analgesic following treatment, compared to children who received a placebo. PMID- 30289372 TI - A person-centered analysis of sleep and emotion dysregulation: Short- and long term links with depression and alcohol use. AB - OBJECTIVE: Our objective was to examine the co-occurrence of sleep problems and emotion dysregulation and its short- and long-term links to depressive symptoms and alcohol use in a sample of university students. METHOD: Participants included 1132 first-year university students from Southern Ontario (70.5% women). Time 1 data were collected in February/March, 2010, and Time 2 data (n = 746) were collected in February/March, 2014. Participants were surveyed about sleep problems and emotion dysregulation (Time 1), and depressive symptoms and alcohol use (Times 1 and 2). RESULTS: A latent class analysis revealed four groups: (1) Low Co-Occurrence, (2) Sleep Problems Only, (3) Emotion Dysregulation Only, and (4) High Co-occurrence. Group 4 had more depressive symptoms than all other groups in both the short- and long-term. CONCLUSIONS: First year university students with high co-occurrence of sleep problems and emotion dysregulation may be a target group for programs focused on reducing adjustment difficulties. PMID- 30289373 TI - Baby Boomer's Substance Abuse and Researcher Indifference. AB - The current older adult population is more likely to need and seek treatment for alcohol and drug abuse than previous cohorts of older adults, which necessitates the need for age-appropriate substance use treatment. Building on previous research that examined the lack of attention on substance use among older adults, this study examines articles addressing substance use disorders among older adults in leading gerontological and substance abuse journals and federal funding between 2011 and 2017. Publications were identified from ten leading gerontological and ten leading substance abuse journals using Medical Subject Heading (MeSH) terms. During this time-period, there were 68 and 44 articles published in gerontology and substance abuse journals respectively related to substance use disorders in older adults. Most (59.8%) addressed alcohol abuse and 7% involved intervention studies. In the 7-year period, there were 13 federal grants. A paucity of published or funded work exists in this area despite growing misuse and treatment seeking among older adults with substance use disorders. Effectively addressing substance abuse in older adults will require a coordinated effort between researchers and practitioners to establish and implement best practices for practitioners to rely on when working with substance abusing older adults. PMID- 30289374 TI - Building resilient families: Developing family interventions for preventing adolescent depression and HIV in low resource settings. AB - Depression contributes significantly to the global burden of disease in low- and middle-income countries. In South Africa, individuals may be at elevated risk for depression due to HIV and AIDS, violence, and poverty. For adolescents, resilience-focused prevention strategies have the potential to reduce onset of depression. Involving families in promoting adolescent mental health is developmentally appropriate, but few existing interventions take a family approach to prevention of adolescent depression. We conducted a qualitative investigation from 2013-2015 to inform the development of a family intervention to prevent adolescent depression in South Africa among families infected or at risk for HIV. Using focus groups with adolescents and parents (eight groups, n = 57), and interviews (n = 25) with clinicians, researchers, and others providing mental health and related services, we identified context-specific factors related to risk for family depression, and explored family interactions around mental health more broadly as well as depression specifically. Findings indicate that HIV and poverty are important risk factors for depression. Future interventions must address linguistic complexities in describing and discussing depression, and engage with the social interpretations and meanings placed upon depression in the South African context, including bewitchment and deviations from prescribed social roles. Participants identified family meetings as a context-appropriate prevention strategy. Family meetings offer opportunities to practice family problem solving, involve other family members in communal parenting during periods of parental depression, and serve as forums for building Xhosa-specific interpretations of resilience. This study will guide the development of Our Family Our Future, a resilience-focused family intervention to prevent adolescent depression (ClinicalTrials.gov #NCT02432352).

AB - This short communication focuses on the potential use of paper sludge ash, a waste product of the paper making industry, as an innovative binder partially replacing cement in concrete with glass aggregate. After preliminary testing using binary or ternary CEM-II mixes with paper sludge ash/pulverised fly ash, a suitable mix for concrete with glass aggregate was identified. Concrete mixes with partial or full natural sand replacement by waste glass aggregate were then produced and showed appropriate strengths and overall similar or better water absorption characteristics than control mixes with natural aggregates, without manifest alkali-silica reaction problems. This shows potential for applications in precast dry mix concrete units based on the required strengths that were achieved. PMID- 30289375 TI - HcPT1.2 participates in Pi acquisition in Hebeloma cylindrosporum external hyphae of ectomycorrhizas under high and low phosphate conditions. AB - Ectomycorrhizal fungi improve tree phosphorus nutrition through transporters specifically localized at soil-hyphae and symbiotic interfaces. In the model symbiosis between the fungus Hebeloma cylindrosporum and the maritime pine (Pinus pinaster), several transporters possibly involved in phosphate fluxes were identified, including three H+:Pi transporters. Among these three, we recently unraveled the function of one of them, named HcPT2, in both pure culture and symbiotic interaction with P. pinaster. Here we investigated the transporter named HcPT1.2, by analyzing inorganic phosphate transport ability in a yeast complementation assay, assessing its expression in the fungus associated or not with the plant, and immunolocalizing the proteins in ectomycorrhizas. We also evaluated the effect of external Pi concentration on expression and localization of HcPT1.2. Our results revealed that HcPT1.2 is involved in Pi acquisition by H. cylindrosporum mycelium, irrespective of the external Pi concentrations.

AB - CRISPR/Cas systems confer molecular immunity against phages and conjugative plasmids in prokaryotes. Recently, CRISPR/Cas9 systems have been used to confer interference against eukaryotic viruses. Here, we engineered Nicotiana benthamiana and tomato (Solanum lycopersicum) plants with the CRISPR/Cas9 system to confer immunity against the Tomato yellow leaf curl virus (TYLCV). Targeting the TYLCV genome with Cas9-single guide RNA at the sequences encoding the coat protein (CP) or replicase (Rep) resulted in efficient virus interference, as evidenced by low accumulation of the TYLCV DNA genome in the transgenic plants. The CRISPR/Cas9-based immunity remained active across multiple generations in the N. benthamiana and tomato plants. Together, our results confirmed the efficiency of the CRISPR/Cas9 system for stable engineering of TYLCV resistance in N. benthamiana and tomato, and opens the possibilities of engineering virus resistance against single and multiple infectious viruses in other crops. PMID- 30289379 TI - Insights into microbiome research 2: Experimental design, sample collection, and shipment. AB - Conducting a robust experiment is not trivial in microbiome research, and as with any study, experimental methods, environmental factors, and analysis methods can affect results. Standards for data collection and analysis are still emerging in the field, and notably, many of the most fundamental issues that concern microbiome studies arise from statistical and experimental design issues. The most important challenge for the field is to integrate new approaches that are unique to microbiome studies, while remembering standard practices that are broadly applicable to all scientific studies. In this section, attention is focused on sample collection, storage and shipping of microbiome-related samples, and how careful, purposeful design can increase the statistical power of these studies.

AB - Waterlogging stress has two phases like waterlogging phase and post-waterlogging phase where both are injurious to plants. Susceptible plants normally die at post waterlogging phase due to damaged root system, sudden rexoygenation, dehydration and photoinhibition of the desubmerged tissues. Formation of reactive oxygen species (ROS) is the main result of reoxygenation stress that can cause oxidative damage of the functional tissues responsible for normal physiological activities. There are almost all types of hormones responsible to recover plants from these destructive phenomenons. Among these hormones ethylene and abscisic acid (ABA) are the main regulators to overcome the reoxygenation and drought like stresses in plants at post-waterlogging condition. The balanced crosstalk among the hormones is highly important for the survival of plants at these stresses. So this paper is completely a precise summary of hormonal homeostasis of post waterlogged plants through physiological, biochemical and signaling pathways. PMID- 30289382 TI - Meat and fat quality of Krskopolje pigs reared in conventional and organic production systems. AB - Data on production traits of the only Slovenian autochthonous pig breed, the Krskopolje pig, is very scarce. Krskopolje pigs are reared in conventional and organic production systems, which were compared in the present study. After weaning, 24 barrows were assigned within litter to either conventional (CON) or organic (ECO) rearing system. Group CON (n=12) was housed indoors in two pens (7.5 m2) with partly slatted floor. Group ECO (n=12) was held in a sty with sheltered area (concrete floor, bedded with straw, 16 m2) and outdoor paddock area (100 m2). The trial started when pigs had 68+/-8 kg BW and 157+/-6 days of age. Two diets were formulated with equivalent ingredients and composition. For ECO diet the ingredients used were ecological. Group ECO received a diet with 12.4 MJ metabolisable energy (ME) per kilogram and 12.9% CP and group CON a diet with 12.7 MJ ME/kg and 13.6% CP. Feed distribution was limited to 3.5 kg per pig daily. In line with the rules for organic production, ECO pigs were additionally given alfalfa hay ad libitum. After 73 days on trial, the pigs were slaughtered and carcass, meat and fat quality was evaluated. Meat quality traits (pH, colour, water holding capacity), fatty acid composition, lipid and protein oxidation, collagen content and solubility were analysed in longissimus lumborum (LL) muscle. Fatty acid composition, lipid oxidation, and vitamins A and E concentrations were determined in backfat. There were no significant differences in growth rate and carcass traits between ECO and CON pigs, however, ECO pigs tended (P<0.10) to have higher daily gain and lower dressing percentage, higher (P<0.001) pH 45 min and lower (P<0.01) pH 24 h postmortem, affecting (P<0.10) also water holding capacity and objective colour parameters (P<0.05) of LL muscle. There were no differences in intramuscular fat (IMF) content of LL muscle, however, IMF of ECO pigs had lower (P<0.05) proportion of saturated and higher (P<0.01) proportion of monounsaturated fatty acids accompanied by higher (P<0.001) values of thiobarbituric reactive substances (TBARS). In backfat, ECO pigs showed lower (P<0.05) vitamin E content, higher (P<0.001) TBARS, higher (P<0.01) degree of unsaturation (percentage of polyunsaturated fatty acids), and also higher (P<0.05) vitamin A concentration than CON pigs, which can be related to alfalfa hay supplementation of ECO pigs. In brief, organic rearing of Krskopolje pigs did not affect performances but had an effect on meat and fat quality. PMID- 30289383 TI - A carbapenem-resistant clinical isolate of Aeromonas hydrophila in Japan harbouring an acquired gene encoding GES-24 beta-lactamase. AB - Several species of Aeromonas produce the enzyme CphA metallo-beta-lactamase. This study describes an isolate of Aeromonas hydrophila harbouring an acquired gene encoding the carbapenemase GES-24. This isolate was obtained from an inpatient in Okinawa, Japan, with no apparent record of travelling overseas. The minimum inhibitory concentrations of carbapenems against this isolate were 8 ug ml-1 for imipenem and 16 ug ml-1 for meropenem. Recombinant GES-24 hydrolyzed all of the tested beta-lactams, including imipenem and meropenem. The genomic environment surrounding blaGES-24 was intI1-blaGES-24-aac(6')-IIc-qacEdelta1-sulI-orfX-tetR tetE. This is the first report of A. hydrophila producing a GES-type carbapenemase. PMID- 30289384 TI - The decoration of specialized metabolites influences stylar development. AB - Plants produce many different specialized (secondary) metabolites that function in solving ecological challenges; few are known to function in growth or other primary processes. 17-Hydroxygeranylinalool diterpene glycosides (DTGs) are abundant herbivory-induced, structurally diverse and commonly malonylated defense metabolites in Nicotiana attenuata plants. By identifying and silencing a malonyltransferase, NaMaT1, involved in DTG malonylation, we found that DTG malonylation percentages are normally remarkably uniform, but when disrupted, result in DTG-dependent reduced floral style lengths, which in turn result from reduced stylar cell sizes, IAA contents, and YUC activity; phenotypes that could be restored by IAA supplementation or by silencing the DTG pathway. Moreover, the Nicotiana genus-specific JA-deficient short-style phenotype also results from alterations in DTG malonylation patterns. Decorations of plant specialized metabolites can be tuned to remarkably uniform levels, and this regulation plays a central but poorly understood role in controlling the development of specific plant parts, such as floral styles. PMID- 30289385 TI - Crystal structure of the full Swi2/Snf2 remodeler Mot1 in the resting state. AB - Swi2/Snf2 ATPases remodel protein:DNA complexes in all of the fundamental chromosome-associated processes. The single-subunit remodeler Mot1 dissociates TATA box-binding protein (TBP):DNA complexes and provides a simple model for obtaining structural insights into the action of Swi2/Snf2 ATPases. Previously we reported how the N-terminal domain of Mot1 binds TBP, NC2 and DNA, but the location of the C-terminal ATPase domain remained unclear (Butryn et al., 2015). Here, we report the crystal structure of the near full-length Mot1 from Chaetomium thermophilum. Our data show that Mot1 adopts a ring like structure with a catalytically inactive resting state of the ATPase. Biochemical analysis suggests that TBP binding switches Mot1 into an ATP hydrolysis-competent conformation. Combined with our previous results, these data significantly improve the structural model for the complete Mot1:TBP:DNA complex and suggest a general mechanism for Mot1 action. PMID- 30289386 TI - Simulation of spontaneous G protein activation reveals a new intermediate driving GDP unbinding. AB - Activation of heterotrimeric G proteins is a key step in many signaling cascades. However, a complete mechanism for this process, which requires allosteric communication between binding sites that are ~30 A apart, remains elusive. We construct an atomically detailed model of G protein activation by combining three powerful computational methods: metadynamics, Markov state models (MSMs), and CARDS analysis of correlated motions. We uncover a mechanism that is consistent with a wide variety of structural and biochemical data. Surprisingly, the rate limiting step for GDP release correlates with tilting rather than translation of the GPCR-binding helix 5. beta-Strands 1 - 3 and helix 1 emerge as hubs in the allosteric network that links conformational changes in the GPCR-binding site to disordering of the distal nucleotide-binding site and consequent GDP release. Our approach and insights provide foundations for understanding disease-implicated G protein mutants, illuminating slow events in allosteric networks, and examining unbinding processes with slow off-rates. PMID- 30289387 TI - Feedback optimizes neural coding and perception of natural stimuli. AB - Growing evidence suggests that sensory neurons achieve optimal encoding by matching their tuning properties to the natural stimulus statistics. However, the underlying mechanisms remain unclear. Here we demonstrate that feedback pathways from higher brain areas mediate optimized encoding of naturalistic stimuli via temporal whitening in the weakly electric fish Apteronotus leptorhynchus. While one source of direct feedback uniformly enhances neural responses, a separate source of indirect feedback selectively attenuates responses to low frequencies, thus creating a high-pass neural tuning curve that opposes the decaying spectral power of natural stimuli. Additionally, we recorded from two populations of higher brain neurons responsible for the direct and indirect descending inputs. While one population displayed broadband tuning, the other displayed high-pass tuning and thus performed temporal whitening. Hence, our results demonstrate a novel function for descending input in optimizing neural responses to sensory input through temporal whitening that is likely to be conserved across systems and species. PMID- 30289388 TI - The ectodomains determine ligand function in vivo and selectivity of DLL1 and DLL4 toward NOTCH1 and NOTCH2 in vitro. AB - DLL1 and DLL4 are Notch ligands with high structural similarity but context dependent functional differences. Here, we analyze their functional divergence using cellular co-culture assays, biochemical studies, and in vivo experiments. DLL1 and DLL4 activate NOTCH1 and NOTCH2 differently in cell-based assays and this discriminating potential lies in the region between the N-terminus and EGF repeat three. Mice expressing chimeric ligands indicate that the ectodomains dictate ligand function during somitogenesis, and that during myogenesis even regions C-terminal to EGF3 are interchangeable. Substitution of NOTCH1-interface residues in the MNNL and DSL domains of DLL1 with the corresponding amino acids of DLL4, however, does not disrupt DLL1 function in vivo. Collectively, our data show that DLL4 preferentially activates NOTCH1 over NOTCH2, whereas DLL1 is equally effective in activating NOTCH1 and NOTCH2, establishing that the ectodomains dictate selective ligand function in vivo, and that features outside the known binding interface contribute to their differences. PMID- 30289390 TI - Laparoscopic splenectomy and azygoportal disconnection combining with pre- and postoperative endoscopic intervention - A sandwich-style sequential therapy for portal hypertensive bleeding: A retrospective cohort study. AB - BACKGROUND/AIMS: In patients who survive the first esophageal variceal bleeding (EVB) resulting from portal hypertension, the probability of fatal esophageal variceal re-bleeding (EVR) is high. We have developed a sandwich-style sequential therapy combining laparoscopic splenectomy and azygoportal disconnection (LSD) with preoperative and postoperative endoscopic intervention (LSDE). The aim of the present study was to investigate whether LSDE is safe and effective and to evaluate whether the postoperative EVR rate for LSDE was lower than that for LSD without periodical postoperative endoscopic intervention (NLSDE). MATERIALS AND METHODS: We retrospectively investigated the outcomes of 226 patients with cirrhosis with EVB and secondary hypersplenism who all received preoperative endoscopic variceal ligation (EVL) to manage emergency EVB then underwent NLSDE (n=106) or LSDE (n=120) between February 2012 and April 2016. The perioperative and follow-up variables of the two groups were evaluated. RESULTS: Between the two groups, there were no differences in number of blood transfusions, intraoperative blood loss, postoperative complications, and hospital stay. LSDE showed shorter operation time (p=0.001) and lower EVR rates during the periods ranging from 1 to 12 months, 4 to 6 months, 4 to 12 months, and 7 to 12 months (all p<0.05) than NLSDE. Dynamic changes in the diameter of the esophageal varices and the rates of EVL in the LSDE group both decreased gradually and significantly over the 12-month follow-up period (all p<0.0001). CONCLUSION: Laparoscopic splenectomy and azygoportal disconnection with periodical postoperative endoscopy is safe and effective for reducing the EVR rate in cirrhotic portal hypertension. PMID- 30289391 TI - Predictors of poor outcomes in 488 patients with herbinduced liver injury. AB - BACKGROUND/AIMS: Herb-induced liver injury (HILI) can lead to chronic liver injury, liver transplantation, or even death. This study aimed to identify the predictors of poor HILI outcomes, especially chronic HILI. MATERIALS AND METHODS: Clinical data of 488 patients with HILI were retrospectively analyzed from a Chinese center between January 2010 and January 2014. Logistic regression and C statistic were used to identify risk factors and prognostic models for HILI outcomes. RESULTS: In all patients, 69 (14.1%) developed chronic HILI, and 20 (4.1%) died due to liver injury or underwent liver transplantation. To predict the fatal HILI prognosis, the model for end-stage liver disease (MELD) with a C statistic of 0.981 (95%CI 0.968-0.995) was better than Hy's law (C-statistic 0.569; 95%CI 0.449-0.689). The latency, course of peak alanine aminotransferase decreasing >=50% after discontinuation of herb application, peak triglyceride value, and platelet count at liver injury onset were identified as independent risk factors for chronicity with the adjusted odds ratios of 1.268 (95% confidence interval [CI] 1.034-1.554), 2.303 (95%CI 1.588-3.340), 0.580 (95%CI 0.343-0.978), and 0.183 (95%CI 0.091-0.368), respectively. A prognostic model for chronic HILI based on these four factors yielded the best prediction with a C statistic of 0.812 (95%CI 0.755-0.868), compared with MELD (C-statistic 0.506; 95%CI 0.431-0.581) and Hy's law (C-statistic 0.418; 95%CI 0.343-0.492). CONCLUSION: Model for end-stage liver disease can be used to predict the fatal prognosis of HILI. A long latency, slow recovery, and low triglyceride value and platelet counts are important determinants for chronic HILI. PMID- 30289392 TI - Low molecular weight heparin treatment of acute moderate and severe pancreatitis: A randomized, controlled, open-label study. AB - BACKGROUND/AIMS: Acute pancreatitis (AP) runs a moderately severe and severe course in 20%-30% of cases. The purpose of the present study was to determine the effect of low molecular weight heparin (LMWH) for the prevention of pancreatic necrosis (PN) in moderately severe and severe AP (MSAP). MATERIALS AND METHODS: A total of 100 patients with MSAP were randomized to receive either standard care (SC) or SC plus LMWH. LMWH was administered at 1 mg/kg via subcutaneous injection twice a day between days 1 and 7. The revised Atlanta criteria were used in the diagnosis of MSAP. Patients with a Harmless AP Score of >=1 and a Balthazar computed tomography (CT) score of D and E were included in the study. RESULTS: The mean age+/-SD of the patients (46 male and 54 female) was 52+/-19 years (range, 17-100). There were 50 patients in each group. On admission, clinical and laboratory parameters and Balthazar CT scores were similar between the groups. Initially, PN was present in one patient in the LMWH group and two in the SC group. Over the course, PN developed in 3 (6.1%) patients in the LMWH group and 11 (22.9%) in the SC group (p<0.05). Local and systemic complications were significantly lower in the LMWH group (p<0.05). No hemorrhagic complication occurred. Mortality was not significantly different between the groups (p=0.056). CONCLUSION: Low molecular weight heparin treatment is safe and provides better prognosis in MSAP. PMID- 30289389 TI - Multiple serine transposase dimers assemble the transposon-end synaptic complex during IS607-family transposition. AB - IS607-family transposons are unusual because they do not have terminal inverted repeats or generate target site duplications. They encode two protein-coding genes, but only tnpA is required for transposition. Our X-ray structures confirm that TnpA is a member of the serine recombinase (SR) family, but the chemically inactive quaternary structure of the dimer, along with the N-terminal location of the DNA binding domain, are different from other SRs. TnpA dimers from IS1535 cooperatively associate with multiple subterminal repeats, which together with additional nonspecific binding, form a nucleoprotein filament on one transposon end that efficiently captures a second unbound end to generate the paired-end complex (PEC). Formation of the PEC does not require a change in the dimeric structure of the catalytic domain, but remodeling of the C-terminal alpha-helical region is involved. We posit that the PEC recruits a chemically-active conformer of TnpA to the transposon end to initiate DNA chemistry. PMID- 30289393 TI - Relationship between irritable bowel syndrome and plasma and tissue ghrelin levels. AB - BACKGROUND/AIMS: This study aimed to evaluate the relationship between irritable bowel syndrome (IBS) and plasma and tissue ghrelin levels. MATERIALS AND METHODS: Patients who had undergone gastroscopy procedure for any reason previously were enrolled in the study. Among these, patients with IBS symptoms were evaluated according to the Roma III criteria. The healthy control group comprised patients with no IBS symptom and had undergone gastroscopy procedure for another reason. The plasma ghrelin level and tissue ghrelin level obtained by immunohistochemical examination of biopsy specimens taken from the gastric antrum and corpus were evaluated in all participants. RESULTS: The mean age of 90 participants was 43.64?}12.64 years. The median value of the plasma ghrelin level was 3.29 (1.2 12.7) in the diarrhea group (IBS-D), 1.49 (0.82-7.08) in the constipation group (IBS-C), and 1.5 (0.2-3.7) in the control group. The plasma ghrelin levels between the groups were found to be significantly higher in IBS-D than in IBS-C and the control groups (p=0.001 and p=0.001, respectively). On comparing antral mucosal gland biopsy outcomes among the groups, staining intensity score was found to be significantly high in IBS-C as compared with the control group, whereas no significant difference was observed between IBS-D and the control groups (p=0.020 and p=0.429, respectively). CONCLUSION: The plasma ghrelin level in IBS-D and the staining intensity in the antral mucosal gland in IBS-C were found to be significantly higher. In addition, there was no difference between the groups in terms of ghrelin staining intensity in the gastric corpus. PMID- 30289394 TI - Positive effect of single nucleotide RAD51 135G>C polymorphism and low Ku70 protein expression on female rectal cancer patients survival after preoperative radiotherapy. AB - BACKGROUND/AIMS: This is a retrospective analysis of 103 patients having locally advanced rectal cancer who received short-course radiotherapy (SCRT). The objective of the study was to check whether a polymorphism in the RAD51 gene (135 G>C), Ku70 protein expression, and tumor microenvironment: proliferation rate measured by BrdUrdLI and Ki-67LI, hypoxia (glucose transporter-1 expression), P53 protein expression, and DNA ploidy can influence DNA repair capacity, the factors contributing to patient overall survival (OS) and the incidence of recurrences and metastases. MATERIALS AND METHODS: RAD51 (135 G>C) polymorphism was evaluated using restriction fragment length polymorphism polymerase chain reaction, and proteins were identified using immunohistochemistry. RESULTS: There were 3 (2.9%) tumors with RAD51 CC, 75 (72.8%) with GG, and 25 (24.3%) with GC genotypes. The median follow-up time was 63.1 months (range 2-120). Patients with CC genotype survived significantly longer than those with GG and GC genotypes and did not develop any recurrences or distant metastases. Female patients with Ku70 expression (<=75.1) or RAD51CC genotype (impaired DNA damage repair and radiosensitive) had significantly longer OS (p=0.013) than those with Ku70>75.1 % or RAD51GG,GC (radioresistant phenotype) and male patients in the log-rank test. In multivariate analysis, positive prognostic factors for OS in the male patients were grade=1 and <=17 days break in the treatment, whereas in the female subgroup, only radiosensitive phenotype (Ku70 <=75.1% or RAD51CC genotype). CONCLUSION: To the best of our knowledge, this is the first study to provide evidence for the positive effect of CC genotype of RAD51 or low Ku70 expression on OS in females with rectal cancer after SCRT. PMID- 30289395 TI - The evaluation of the effect of Helicobacter pylori infection on choroidal thickness. AB - BACKGROUND/AIMS: To evaluate the effects of Helicobacter pylori infection on choroidal thickness (CT) using enhanced depth imaging spectral domain-optical coherence tomography (SD-OCT). MATERIALS AND METHODS: A total of 63 right eyes of 63 patients who tested positive for H. pylori (Group 1) and 46 right eyes of 46 patients who tested negative for H. pylori (Group 2) were evaluated. The CTs at the subfoveal area and at 1 mm ranging up to 3 mm from the fovea at the nasal and temporal quadrants were measured and compared. After the eradication of H. pylori, the CT values were also compared with the pre-eradication values in 38 patients. RESULTS: The mean age of patients was 43.6?}9.5 years in Group 1 and 46.6?}11.5 years in Group 2 (p=0.13). Differences in CT values between Groups 1 and 2 before and after H. pylori eradication were not statistically significant (p>0.05 for all values). CONCLUSION: The CT values of H. pylori positive and H. pylori negative patients were similar. Eradication of H. pylori infection appears to have produced no change in short-term CT. PMID- 30289396 TI - Molecular and presymptomatic analysis of a Moroccan Lynch syndrome family revealed a novel frameshift MLH1 germline mutation. AB - Lynch syndrome (LS) is an autosomal dominant disorder characterized by an increased risk of extracolonic cancers and early age of onset. It is associated with germline mutations in the DNA mismatch repair (MMR) genes. We report a case of a patient with colorectal cancer referred to our medical genetics department for molecular analysis and genetic counseling. The proband is a 64-year-old woman diagnosed with a tumor of the cecum. Histopathological examination showed a moderately differentiated mucinous adenocarcinoma categorized by pT3 N0. Analysis of her pedigree revealed three siblings who had colon cancer, as well as one relative with brain cancer. Based on these findings, molecular genetic investigation was found to be necessary in order to identify the disease-causing mutation. Immunohistochemistry staining of MMR proteins was performed on the tumor sample of the index proband. Mutational analysis of the MLH1/MSH2 genes was carried out. Analysis was extended to the family members and the general population. This led to the identification of a heterozygous frameshift duplication in the MLH1 gene at position 910 (c.910dupG). Three siblings had inherited the mutation from their mother, two of whom were asymptomatic at the time of diagnosis. To the best of our knowledge, this is a novel pathogenic duplication that has not been reported in the databases and literature. The outcome of the present case suggests that this mutation was the primary cause of LS in the family.

AB - BACKGROUND/AIMS: Hypertriglyceridemia (HTG) is the third most common cause of acute pancreatitis. In patients with severe HTG (TG level>1000 mg/dL), it may be beneficial to immediately lower the levels of triglyceride (TG) and chylomicrons. In this study, we present one of the largest case series on the use of therapeutic plasma exchange (TPE) for hypertriglyceridemia-induced acute pancreatitis (HTG-AP). MATERIALS AND METHODS: Overall, 33 patients who were admitted to our clinic for HTG-AP and underwent TPE between January 2007 and July 2017 were included in the study. Clinical data and outcomes and the reduction of triglyceride levels were examined retrospectively. RESULTS: The TG level decreased by 54.4%, and the total cholesterol level decreased by 52.1% after one TPE session. The TG decrease after the second TPE session was found to be 79.4%. There were 20 (60.6%) patients with mild acute pancreatitis, 10 (30.3%) patients with moderetaly severe acute pancreatitis, and 3 (9.1%) patients with severe acute pancreatitis based on the categorization according to the revised Atlanta criteria. Regarding local complications, the acute peripancreatic fluid collection was observed in 13 (39.4%) patients, acute necrotic collection was observed in 1 (3%) patient, walled-off necrosis was observed in 1 (3%) patient, and pancreatic pseudocyst was not observed in any patient. Mortality was not determined in patients with mild and moderately severe acute pancreatitis, and its rate was 33.3% in patients with severe acute pancreatitis. The overall mortality rate was 3%. No significant complications related to TPE were noted. CONCLUSION: TPE is a safe and helpful therapeutic treatment method for patients with HTG-AP and may be considered particularly in patients with severe acute pancreatitis.

AB - The biological conversion of lignocellulosic matter into high-value chemicals or biofuels is of increasing industrial importance as the sector slowly transitions away from nonrenewable sources. Many industrial processes involve the use of cellulolytic enzyme cocktails - a selection of glycoside hydrolases and, increasingly, polysaccharide oxygenases - to break down recalcitrant plant polysaccharides. ORFs from the genome of Teredinibacter turnerae, a symbiont hosted within the gills of marine shipworms, were identified in order to search for enzymes with desirable traits. Here, a putative T. turnerae glycoside hydrolase from family 8, hereafter referred to as TtGH8, is analysed. The enzyme is shown to be active against beta-1,4-xylan and mixed-linkage (beta-1,3,beta 1,4) marine xylan. Kinetic parameters, obtained using high-performance anion exchange chromatography with pulsed amperometric detection and 3,5 dinitrosalicyclic acid reducing-sugar assays, show that TtGH8 catalyses the hydrolysis of beta-1,4-xylohexaose with a kcat/Km of 7.5 * 107 M-1 min-1 but displays maximal activity against mixed-linkage polymeric xylans, hinting at a primary role in the degradation of marine polysaccharides. The three-dimensional structure of TtGH8 was solved in uncomplexed and xylobiose-, xylotriose- and xylohexaose-bound forms at approximately 1.5 A resolution; the latter was consistent with the greater kcat/Km for hexasaccharide substrates. A 2,5B boat conformation observed in the -1 position of bound xylotriose is consistent with the proposed conformational itinerary for this class of enzyme. This work shows TtGH8 to be effective at the degradation of xylan-based substrates, notably marine xylan, further exemplifying the potential of T. turnerae for effective and diverse biomass degradation. PMID- 30289407 TI - Co-crystallization of human inositol monophosphatase with the lithium mimetic L 690,330. AB - Lithium, which is still the gold standard in the treatment of bipolar disorder, has been proposed to inhibit inositol monophosphatase (IMPase) and is hypothesized to exert its therapeutic effects by attenuating phosphatidylinositol (PI) cell signalling. Drug-discovery efforts have focused on small-molecule lithium mimetics that would specifically inhibit IMPase without exhibiting the undesired side effects of lithium. L-690,330 is a potent bisphosphonate substrate based inhibitor developed by Merck Sharp & Dohme. To aid future structure-based inhibitor design, determination of the exact binding mechanism of L-690,330 to IMPase was of interest. Here, the high-resolution X-ray structure of human IMPase in complex with L690,330 and manganese ions determined at 1.39 A resolution is reported. PMID- 30289406 TI - Precipitant-ligand exchange technique reveals the ADP binding mode in Mycobacterium tuberculosis dethiobiotin synthetase. AB - Dethiobiotin synthetase from Mycobacterium tuberculosis (MtDTBS) is a promising antituberculosis drug target. Small-molecule inhibitors that target MtDTBS provide a route towards new therapeutics for the treatment of antibiotic resistant tuberculosis. Adenosine diphosphate (ADP) is an inhibitor of MtDTBS; however, structural studies into its mechanism of inhibition have been unsuccessful owing to competitive binding to the enzyme by crystallographic precipitants such as citrate and sulfate. Here, a crystallographic technique termed precipitant-ligand exchange has been developed to exchange protein-bound precipitants with ligands of interest. Proof of concept for the exchange method was demonstrated using cytidine triphosphate (CTP), which adopted the same binding mechanism as that obtained with traditional crystal-soaking techniques. Precipitant-ligand exchange also yielded the previously intractable structure of MtDTBS in complex with ADP solved to 2.4 A resolution. This result demonstrates the utility of precipitant-ligand exchange, which may be widely applicable to protein crystallography. PMID- 30289405 TI - Rational modification of vanillin derivatives to stereospecifically destabilize sickle hemoglobin polymer formation. AB - Increasing the affinity of hemoglobin for oxygen represents a feasible and promising therapeutic approach for sickle cell disease by mitigating the primary pathophysiological event, i.e. the hypoxia-induced polymerization of sickle hemoglobin (Hb S) and the concomitant erythrocyte sickling. Investigations on a novel synthetic antisickling agent, SAJ-310, with improved and sustained antisickling activity have previously been reported. To further enhance the biological effects of SAJ-310, a structure-based approach was employed to modify this compound to specifically inhibit Hb S polymer formation through interactions which perturb the Hb S polymer-stabilizing alphaF-helix, in addition to primarily increasing the oxygen affinity of hemoglobin. Three compounds, TD-7, TD-8 and TD 9, were synthesized and studied for their interactions with hemoglobin at the atomic level, as well as their functional and antisickling activities in vitro. X ray crystallographic studies with liganded hemoglobin in complex with TD-7 showed the predicted mode of binding, although the interaction with the alphaF-helix was not as strong as expected. These findings provide important insights and guidance towards the development of molecules that would be expected to bind and make stronger interactions with the alphaF-helix, resulting in more efficacious novel therapeutics for sickle cell disease. PMID- 30289408 TI - Identification of the site of oxidase substrate binding in Scytalidium thermophilum catalase. AB - The catalase from Scytalidium thermophilum is a homotetramer containing a heme d in each active site. Although the enzyme has a classical monofunctional catalase fold, it also possesses oxidase activity towards a number of small organics, including catechol and phenol. In order to further investigate this, the crystal structure of the complex of the catalase with the classical catalase inhibitor 3 amino-1,2,4-triazole (3TR) was determined at 1.95 A resolution. Surprisingly, no binding to the heme site was observed; instead, 3TR occupies a binding site corresponding to the NADPH-binding pocket in mammalian catalases at the entrance to a lateral channel leading to the heme. Kinetic analysis of site-directed mutants supports the assignment of this pocket as the binding site for oxidase substrates. PMID- 30289410 TI - Crystallography on a chip - without the chip: sheet-on-sheet sandwich. AB - Crystallography chips are fixed-target supports consisting of a film (for example Kapton) or wafer (for example silicon) that is processed using semiconductor microfabrication techniques to yield an array of wells or through-holes in which single microcrystals can be lodged for raster-scan probing. Although relatively expensive to fabricate, chips offer an efficient means of high-throughput sample presentation for serial diffraction data collection at synchrotron or X-ray free electron laser (XFEL) sources. Truly efficient loading of a chip (one microcrystal per well and no wastage during loading) is nonetheless challenging. The wells or holes must match the microcrystal size of interest, requiring that a large stock of chips be maintained. Raster scanning requires special mechanical drives to step the chip rapidly and with micrometre precision from well to well. Here, a 'chip-less' adaptation is described that essentially eliminates the challenges of loading and precision scanning, albeit with increased, yet still relatively frugal, sample usage. The device consists simply of two sheets of Mylar with the crystal solution sandwiched between them. This sheet-on-sheet (SOS) sandwich structure has been employed for serial femtosecond crystallography data collection with micrometre-sized crystals at an XFEL. The approach is also well suited to time-resolved pump-probe experiments, in particular for long time delays. The SOS sandwich enables measurements under XFEL beam conditions that would damage conventional chips, as documented here. The SOS sheets hermetically seal the sample, avoiding desiccation of the sample provided that the X-ray beam does not puncture the sheets. This is the case with a synchrotron beam but not with an XFEL beam. In the latter case, desiccation, setting radially outwards from each punched hole, sets lower limits on the speed and line spacing of the raster scan. It is shown that these constraints are easily accommodated. PMID- 30289409 TI - Using sound pulses to solve the crystal-harvesting bottleneck. AB - Crystal harvesting has proven to be difficult to automate and remains the rate limiting step for many structure-determination and high-throughput screening projects. This has resulted in crystals being prepared more rapidly than they can be harvested for X-ray data collection. Fourth-generation synchrotrons will support extraordinarily rapid rates of data acquisition, putting further pressure on the crystal-harvesting bottleneck. Here, a simple solution is reported in which crystals can be acoustically harvested from slightly modified MiTeGen In Situ-1 crystallization plates. This technique uses an acoustic pulse to eject each crystal out of its crystallization well, through a short air column and onto a micro-mesh (improving on previous work, which required separately grown crystals to be transferred before harvesting). Crystals can be individually harvested or can be serially combined with a chemical library such as a fragment library. PMID- 30289413 TI - Structural insights into the recognition of phosphorylated Hop1 by Mek1. AB - The FHA domain-containing protein Mek1 is a meiosis-specific kinase that is involved in the regulation of interhomolog recombination in meiosis in Saccharomyces cerevisiae. The recruitment and activation of Mek1 require the phosphorylation of the chromosome axis protein Hop1 at Thr318 (pT318), which is necessary for recognition by the Mek1 FHA domain. Here, crystal structures of the Mek1 FHA domain in the apo state and in complex with the Hop1 pT318 peptide are presented, demonstrating that the hydrophobic residues Phe320 and Val321 at the pT+2 and pT+3 positions in the ligand contribute to the preferential recognition. It was further found that in Schizosaccharomyces pombe Mek1 FHA binds both pT15 in its N-terminal SQ/TQ cluster domain (SCD) and pT270 in the Hop1 SCD. The results revealed the structural basis for the preferential recognition of phosphorylated Hop1 by Mek1 in S. cerevisiae and facilitate the understanding of the interaction between the S. pombe Mek1 FHA domain and its binding targets. PMID- 30289411 TI - The X-ray structure of human calbindin-D28K: an improved model. AB - Calbindin-D28K is a widely expressed calcium-buffering cytoplasmic protein that is involved in many physiological processes. It has been shown to interact with other proteins, suggesting a role as a calcium sensor. Many of the targets of calbindin-D28K are of therapeutic interest: for example, inositol monophosphatase, the putative target of lithium therapy in bipolar disorder. Presented here is the first crystal structure of human calbindin-D28K. There are significant deviations in the tertiary structure when compared with the NMR structure of rat calbindin-D28K (PDB entry 2g9b), despite 98% sequence identity. Small-angle X-ray scattering (SAXS) indicates that the crystal structure better predicts the properties of calbindin-D28K in solution compared with the NMR structure. Here, the first direct visualization of the calcium-binding properties of calbindin-D28K is presented. Four of the six EF-hands that make up the secondary structure of the protein contain a calcium-binding site. Two distinct conformations of the N-terminal EF-hand calcium-binding site were identified using long-wavelength calcium single-wavelength anomalous dispersion (SAD). This flexible region has previously been recognized as a protein-protein interaction interface. SAXS data collected in both the presence and absence of calcium indicate that there are no large structural differences in the globular structure of calbindin-D28K between the calcium-loaded and unloaded proteins. PMID- 30289412 TI - High-resolution crystal structures of the D1 and D2 domains of protein tyrosine phosphatase epsilon for structure-based drug design. AB - Here, new crystal structures are presented of the isolated membrane-proximal D1 and distal D2 domains of protein tyrosine phosphatase epsilon (PTPE), a protein tyrosine phosphatase that has been shown to play a positive role in the survival of human breast cancer cells. A triple mutant of the PTPE D2 domain (A455N/V457Y/E597D) was also constructed to reconstitute the residues of the PTPE D1 catalytic domain that are important for phosphatase activity, resulting in only a slight increase in the phosphatase activity compared with the native D2 protein. The structures reported here are of sufficient resolution for structure based drug design, and a microarray-based assay for high-throughput screening to identify small-molecule inhibitors of the PTPE D1 domain is also described. PMID- 30289414 TI - Remoulding a MOF's pores by auxiliary ligand introduction for stability improvement and highly selective CO2-capture. AB - A new highly porous mixed-valence metal-organic framework, Co-pydc, was synthesized and characterized. Upon guest loss, Co-pydc irreversibly transformed to a closed structure and lost pore functionality. Then an auxiliary ligand was introduced as a girder to support the framework in the synthesis process, and successfully afforded a new porous MOF, Co-pydc-TPB. This displays a considerably enhanced robust framework which is resistant to guest loss and stable up to 400 degrees C, retains single-crystallinity at 300 degrees C, shows good water and alkali resistance, and selective adsorption of CO2 over N2 at room temperature. PMID- 30289415 TI - Application of electrochemical surface plasmon resonance (ESPR) to the study of electroactive microbial biofilms. AB - Electrochemical surface plasmon resonance (ESPR) monitors faradaic processes optically by the change in refractive index that occurs with a change in redox state at the electrode surface. Here we apply ESPR to investigate the anode-grown Geobacter sulfurreducens biofilm (GSB), a model system used to study electroactive microbial biofilms (EABFs) which perform electrochemical reactions using electrodes as metabolic electron acceptors or donors. A substantial body of evidence indicates that electron transfer reactions among hemes of c-type cytochromes (c-Cyt) play major roles in the extracellular electron transfer (EET) pathways that connect intracellular metabolic processes of cells in an EABF to the electrode surface. The results reported here reveal that when the potential of the electrode is changed from relatively oxidizing (0.40 V vs. SHE) to reducing (-0.55 V vs. SHE) and then back to oxidizing, 70% of c-Cyt residing closest to the biofilm/electrode (within hundreds of nm from the electrode surface) appear to remain trapped in the reduced state, requiring as long as 12 hours to be re-oxidized. c-Cyt storing electrons cannot contribute to EET, yet turnover current resulting from cellular oxidation of acetate coupled with EET to the electrode surface is unaffected. This suggests that a relatively small fraction of c-Cyt residing closest to the biofilm/electrode interface is involved in EET while the majority store electrons. The results also reveal that biomass density at the biofilm/electrode interface increases rapidly during lag phase, reaching its maximum value at the onset of exponential biofilm growth when turnover current begins to rapidly increase.

AB - A copper-catalyzed asymmetric propargylic [3+3] cycloaddition with 1H-pyrazol 5(4H)-ones as C,O-bisnucleophiles through the desilylation-activated strategy has been developed. With the catalysis of Cu(OAc)2.H2O in combination with a chiral tridentate P,N,N-ligand, the reaction displayed a broad substrate scope, and thus provided a variety of chiral dihydropyrano[2,3-c]pyrazoles in high yields and with excellent enantioselectivities (up to 96% ee). PMID- 30289417 TI - Bubble-bubble pinch-off in symmetric and asymmetric microfluidic expansion channels for ordered foam generation. AB - By incorporating the techniques of geometrically mediated splitting and bubble bubble breakup, the present work offers a novel microfluidic foam generation system via production of segregated, mono- or bidisperse bubbles at capacities exceeding 10 000 bubbles per second. Bubble-bubble pinch-off is precise at high capillary numbers (Ca > 0.065), generating monodisperse or bidisperse daughter bubbles for a symmetric or an asymmetric expansion respectively. Bi- or tridisperse foam is produced as pinch-off perfectly alternates such that the system contains twice the number of fragmented bubbles as intact bubbles. A relationship between the upstream bubble extension and the capillary number demarcates the different regimes of pinch-off defined with respect to frequency and precision: non-splitting, irregular, polydisperse, and monodisperse (or bidisperse for an asymmetric expansion). For tridisperse foam generation via a fixed asymmetric expansion geometry, the wall bubble confinement can be tuned to adjust the pinch-off accuracy in order to access a spectrum of fragmented bubble size ratios. The simplicity in operating and characterizing our system will enable studies on dynamic bubble interactions and ordered, wet foam applications.

AB - Near-infrared spectroscopy of the C2H2-Ar, Kr complexes was performed in the spectral region overlapping the nu3/nu2 + nu4 + nu5 Fermi-type resonance of C2H2. The experiment was conducted along the HElium NanoDroplet Isolation (HENDI) technique in order to study the coupling dynamics between a floppy molecular system (C2H2-Ar and C2H2-Kr) and a mesoscopic quantum liquid (the droplet). Calculations were performed using a spectral element based close-coupling program and state-of-the-art 2-dimensional potential energy surfaces to determine the bound states of the C2H2-Ar and C2H2-Kr complexes and simulate the observed spectra. This furnished a quantitative basis to unravel how the superfluid and non-superfluid components of the droplet affect the rotation and the deformation dynamics of the hosted complex.

PMID- 30289420 TI - Probing the band gap of liquid ammonia with femtosecond multiphoton ionization spectroscopy. AB - The electronic band gap, i.e. the energy difference between the top of the valence band and the bottom of the conduction band, is widely recognized as the key property characterizing the electronic structure of bulk liquids and liquid solvents like water or ammonia. Here, the band gap of liquid ammonia at 270 K and 300 bar was studied with 2-photon ionization spectroscopy using the solvated electron primary yield as a near-infrared action-spectroscopic probe. The experimentally determined escape probability, which is the fraction of solvated electrons that is able to avoid geminate recombination within the first nanosecond after ionization, was used to extract a value of -(1.27 +/- 0.03) eV for the vertical electron affinity of the liquid. PMID- 30289421 TI - Ultrafast unidirectional chiral rotation in the Z-E photoisomerization of two azoheteroarene photoswitches. AB - Unidirectional rotation represents a very important functional feature in photochemistry, such as in the design of light-driven molecular rotary motors. Great attention has recently been devoted to the unidirectional preference of the torsional motion of azobenzene and other molecules. Azoheteroarenes offer functional advantages over their more conventional azobenzene counterparts due to the introduction of heteroaromatic rings. In this paper, the Z-E photoisomerization dynamics of two azoheteroarenes, 1,2-bis(1-methyl-1H-imidazol 2-yl)diazene and 1,2-bis(1H-imidazol-2-yl)diazene, are investigated with trajectory surface-hopping molecular dynamics at the semi-empirical OM2/MRCI level. Starting from the S1 excited state of the M-helical Z-isomer of both azoheteroarenes, more than 99% of the trajectories decay to their ground states through the M-helical conical intersections by twisting about the central N[double bond, length as m-dash]N double bond. This chiral path preference can be well understood by the energy profiles generated by the linear interpolation between the Franck-Condon geometry of the M-helical Z-isomer and the relevant S1/S0 conical intersections. The Z-E photoisomerization mechanisms of these two azoheteroarenes display a higher preference for unidirectional rotary dynamics under a chiral path than their counterpart azobenzene. PMID- 30289422 TI - Qualitative analysis of antibody-drug conjugates (ADCs): an experimental comparison of analytical techniques of cysteine-linked ADCs. AB - Antibody-drug conjugates (ADCs) are an emerging type of biotherapeutics that utilize multiple tissue-specific antibodies combined with a range of linker designs to enable the transportation and selective release of cytotoxic drugs in close proximity to tumours. Consisting of antibodies conjugated to small drug molecules through a variety of linkers, ADCs are chemically complex analytes. Here we present a unique experimental comparison of four techniques for ADC analysis: hydrophobic interaction chromatography (HIC-UV/Vis), reversed phase liquid chromatography mass spectrometry (RPLC-MS), using either a QToF or an Orbitrap analyser, and matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Four different ADCs consisting of Trastuzumab, monomethyl auristatin E (MMAE) and a peptidic linker moiety differing in their respective stoichiometric ratios in regard to drug-to-antibody ratio (DAR) were used for the comparison. We found that the determined DAR from all techniques was comparable, while the accuracy of the molecular weights for the conjugated light and heavy chain differed more extensively. This indicates that the choice of a mass analyser is more crucial for determining the accurate weights of the light and heavy chains than to evaluate the DAR of a given batch. However, ambiguous DAR assignment in HIC-UV/Vis or bias for either the light or heavy chain fragments in the mass spectrometry-based techniques can influence the obtained average DAR value and the use of complementary techniques is advisable. Out of the four techniques evaluated, HIC-UV/Vis and MALDI required less time to obtain an average DAR value and would therefore be good for initial screenings in the early stages of the discovery phase of new ADCs. PMID- 30289423 TI - Axially perpendicular offset scheme for obtaining Raman spectra of housed samples in glass bottles with minimized glass-peak background. AB - An axially perpendicular offset (APO) scheme based on an axially perpendicular geometrical arrangement of laser illumination and photon detection, enabling spatially offset Raman spectroscopy (SORS), is proposed as a versatile tool for the minimization of the glass background in direct measurements of Raman spectra of samples housed in glass bottles. This strategy is based on the possibility of isolating glass photons from sample photons by properly locating a detector beneath the sample-housing bottle, because glass photons are much more localized near the glass wall while sample photons are widely distributed throughout the bottle. In addition, the curved bottom of the glass vial enabling forming the conical photon-detection volume would be further effective in exclusion of the glass photons in the acquisition of sample spectra. The APO scheme was validated by measuring the Raman spectra of 66% ethanol housed in four glass bottles of different sizes and colors; the measurements were performed by varying the offset distance from 2 mm to 20 mm. The intensity of the glass background decreased rapidly with increasing the offset distance; on the other hand, the variation in the ethanol intensity was relatively insignificant. In all cases, the offset distance of 16 mm minimized the presence of glass background in the spectra, thereby helping to highlight the pure ethanol bands and producing nearly similar sample spectral features regardless of contained bottles. The results of the Monte Carlo simulation were in accordance with the experimental observations, and the suppression of glass photons in the APO scheme was clearly explained and visualized by the simulation. PMID- 30289424 TI - Ethanol, O, and CO adsorption on Pt nanoparticles: effects of nanoparticle size and graphene support. AB - Pt nanoparticles dispersed over carbonaceous supports are widely used as catalysts for different applications, making studies on the interplay between size and support effects indispensable for rational catalyst design. Here, we use DFT calculations to simulate the interaction between O, CO, and ethanol with free platinum cuboctahedral nanoparticles with up to 147 atoms and with the same Pt nanoparticles supported on a single layer of graphene with up to 720 carbon atoms. We compute adsorption energies for each adsorbate on different adsorption sites for supported and unsupported Pt nanoparticles. We show that as the Pt nanoparticle grows the adsorption energy decreases, and that the size effect is more important for O and CO adsorption than for ethanol. We observe that the generalized coordination number of each adsorption site controls the interaction strength for O and CO to a much larger extent than for ethanol. Electronic charge redistributions and density of states projected on the d band of the interacting Pt facets are used to obtain a better understanding of the differences between the electronic interactions for each adsorbate. For Pt nanoparticles supported on graphene, the support effects weaken the adsorption energies for all the adsorbates, but this effect rapidly decreases with larger nanoparticles, and it is only significant for our smallest nanoparticle Pt13. By demonstrating that the effects of nanoparticle size and support are different for ethanol as compared with O and CO, we conclude that it should be possible to modify different parameters in the catalyst design in order to tune the Pt nanoparticle to interact with specific adsorbates. PMID- 30289425 TI - A randomized controlled trial of the impact of protein supplementation on leg lean mass and integrated muscle protein synthesis during inactivity and energy restriction in older persons. AB - Background: In older persons, muscle loss is accelerated during physical inactivity and hypoenergetic states, both of which are features of hospitalization. Protein supplementation may represent a strategy to offset the loss of muscle during inactivity, and enhance recovery on resumption of activity. Objective: We aimed to determine if protein supplementation, with proteins of substantially different quality, would alleviate the loss of lean mass by augmenting muscle protein synthesis (MPS) while inactive during a hypoenergetic state. Design: Participants (16 men, mean +/- SD age: 69 +/- 3 y; 15 women, mean +/- SD age: 68 +/- 4 y) consumed a diet containing 1.6 g protein . kg-1 . d-1, with 55% +/- 9% of protein from foods and 45% +/- 9% from supplements, namely, whey protein (WP) or collagen peptides (CP): 30 g each, consumed 2 times/d. Participants were in energy balance (EB) for 1 wk, then began a period of energy restriction (ER; -500 kcal/d) for 1 wk, followed by ER with step reduction (ER + SR; <750 steps/d) for 2 wk, before a return to habitual activity in recovery (RC) for 1 wk. Results: There were significant reductions in leg lean mass (LLM) from EB to ER, and from ER to ER + SR in both groups (P < 0.001) with no differences between WP and CP or when comparing the change from phase to phase. During RC, LLM increased from ER + SR, but in the WP group only. Rates of integrated muscle protein synthesis decreased during ER and ER + SR in both groups (P < 0.01), but increased during RC only in the WP group (P = 0.05). Conclusions: Protein supplementation did not confer a benefit in protecting LLM, but only supplemental WP augmented LLM and muscle protein synthesis during recovery from inactivity and a hypoenergetic state. This trial was registered at http://www.clinicaltrials.gov as NCT03285737. PMID- 30289427 TI - Bcl-3 promotes proliferation and chemosensitivity in BL1 subtype of TNBC cells. AB - Bcl-3 is an established oncogene in diverse malignant tumors. In this study, we investigated a dual role of Bcl-3 in BL1-subtype triple-negative breast cancer (TNBC). The BL1-subtype TNBC is featured by increasing cell cycle gene expression and the highest sensitivity to chemotherapy among all subtypes. Bcl-3 is associated with a better prognosis in BL1 patients. Bcl-3 knockdown in BL1 cell MDA-MB-468 induces the inhibition of cell proliferation and the G1/S transition arrest by promoting p27 and reducing the expressions of c-Myc and skp2 at mRNA and protein levels. Meanwhile, Bcl-3 enhances the sensitivity of MDA-MB-468 to chemotherapeutics ABX and PTX. Furthermore, the regulation mechanisms are restricted to BL1 cell and do not occur in SUM159PT, a typical MSL subtype of TNBC cell. These data suggest that Bcl-3 may be a potential clinical biomarker for diagnosis, treatment, and prognosis of patients with BL1-subtype TNBC. PMID- 30289426 TI - The Association of Changes in Pain Acceptance and Headache-Related Disability. AB - Background: Migraine accounts for substantial suffering and disability. Previous studies show cross-sectional associations between higher pain acceptance and lower headache-related disability in individuals with migraine, but none has evaluated this association longitudinally during migraine treatment. Purpose: This study evaluated whether changes in pain acceptance were associated with changes in headache-related disability and migraine characteristics in a randomized controlled trial (Women's Health and Migraine) that compared effects of behavioral weight loss (BWL) treatment and migraine education (ME) on headache frequency in women with migraine and overweight/obesity. Methods: This was a post hoc analysis of 110 adult women with comorbid migraine and overweight/obesity who received 16 weeks of either BWL or ME. Linear and nonlinear mixed effects modeling methods were used to test for between-group differences in change in pain acceptance, and also to examine the association between change in pain acceptance and change in headache disability. Results: BWL and ME did not differ on improvement in pain acceptance from baseline across post-treatment and follow up. Improvement in pain acceptance was associated with reduced headache disability, even when controlling for intervention-related improvements in migraine frequency, headache duration, and pain intensity. Conclusions: This study is the first to show that improvements in pain acceptance following two different treatments are associated with greater reductions in headache-related disability, suggesting a potential new target for intervention development.

AB - Background and Aims: In woody species, the juvenile period maintains the axillary meristems in a vegetative stage, unable to flower, for several years. However, in adult trees, some 1-year-old meristems flower whereas others remain vegetative to ensure a polycarpic growth habit. Both types of trees, therefore, have non flowering meristems, and we hypothesize that the molecular mechanism regulating flower inhibition in juvenile trees is different from that in adult trees. Methods: In adult Citrus trees, the main endogenous factor inhibiting flower induction is the growing fruit. Thus, we studied the expression of the main flowering time, identity and patterning genes of trees with heavy fruit load (not flowering adult trees) compared to that of 6-month-old trees (not-flowering juvenile trees). Adult trees without fruits (flowering trees) were used as a control. Second, we studied the expression of the same genes in the meristems of 6-month, and 1-, 3-, 5- and 7-year-old juvenile trees compared to 10-year-old flowering trees. Key Results: The axillary meristems of juvenile trees are unable to transcribe flowering time and patterning genes during the period of induction, although they are able to transcribe the FLOWERING LOCUS T citrus orthologue (CiFT2) in leaves. By contrast, meristems of not-flowering adult trees are able to transcribe the flowering network genes but fail to achieve the transcription threshold required to flower, due to CiFT2 repression by the fruit. Juvenile meristems progressively achieve gene expression, with age-dependent differences from 6 months to 7 years, FD-like and CsLFY being the last genes to be expressed. Conclusions: During the juvenile period the mechanism inhibiting flowering is determined in the immature bud, so that it progressively acquires flowering ability at the gene expression level of the flowering time programme, whereas in the adult tree it is determined in the leaf, where repression of CiFT2 gene expression occurs.

AB - Background and Aims: Sexual dimorphism in morphology, physiology or life history traits is common in dioecious plants at reproductive maturity, but it is typically inconspicuous or absent in juveniles. Although plants of different sexes probably begin to diverge in gene expression both before their reproduction commences and before dimorphism becomes readily apparent, to our knowledge transcriptome-wide differential gene expression has yet to be demonstrated for any angiosperm species. Methods: The present study documents differences in gene expression in both above- and below-ground tissues of early pre-reproductive individuals of the wind-pollinated dioecious annual herb, Mercurialis annua, which otherwise shows clear sexual dimorphism only at the adult stage. Key Results: Whereas males and females differed in their gene expression at the first leaf stage, sex-biased gene expression peaked just prior to, and after, flowering, as might be expected if sexual dimorphism is partly a response to differential costs of reproduction. Sex-biased genes were over-represented among putative sex-linked genes in M. annua but showed no evidence for more rapid evolution than unbiased genes. Conclusions: Sex-biased gene expression in M. annua occurs as early as the first whorl of leaves is produced, is highly dynamic during plant development and varies substantially between vegetative tissues.

PMID- 30289432 TI - The Clinical Significance and Application of Vascular Stiffness Measurements. AB - Increasing evidence points out at vascular stiffness (and in particular aortic stiffness measured by pulse wave velocity) as a reliable biomarker of vascular aging, able to integrate in a single measure the overall burden of cardiovascular (CV) risk factors on the vasculature over time; furthermore, it may be per se a mechanism of disease, by inducing microcirculatory damage and favoring CV events. Increased aortic stiffness has been shown to predict future CV events and improve risk reclassification in those at intermediate risk. However, several questions in this field are still open, limiting the wide use of these tools in the clinical practice. This article will review the basic aspects of physiology of large artery stiffness, as well as current evidence about its possible clinical applications. PMID- 30289434 TI - Modeling liver cancer and therapy responsiveness using organoids derived from primary mouse liver tumors. AB - The current understanding of cancer biology and development of effective treatments for cancer remain far from satisfactory. This in turn heavily relies on the availability of easy and robust model systems that resemble the architecture/physiology of the tumors in patients to facilitate research. Cancer research in vitro has mainly been based on the use of immortalized 2D cancer cell lines that deviate in many aspects from the original primary tumors. The recent development of the organoid technology allowing generation of organ-buds in 3D culture from adult stem cells has endowed the possibility of establishing stable culture from primary tumors. Although culturing organoids from liver tumors is thought to be difficult, we now convincingly demonstrate the establishment of organoids from mouse primary liver tumors. We have succeeded in culturing 91 lines from 129 liver tissue/tumors. These organoids can be grown in long-term cultures in vitro. About 20% of these organoids form tumors in immunodeficient mice upon (serial) transplantation, confirming their tumorigenic and self-renewal properties. Interestingly, single cells from the tumor organoids have high efficiency of organoid initiation, and a single organoid derived from a cancer cell is able to initiate a tumor in mice, indicating the enrichment of tumor initiating cells in the tumor organoids. Furthermore, these organoids recapitulate, to some extent, the heterogeneity of liver cancer in patients, with respect to phenotype, cancer cell composition and treatment response. These model systems shall provide enormous opportunities to advance our research on liver cancer (stem cell) biology, drug development and personalized medicine.

AB - Background: Many dietary indexes exist for chronic disease prevention, but the optimal dietary pattern for colorectal cancer prevention is unknown. Objective: We sought to determine associations between adherence to various dietary indexes and incident colorectal cancer in 2 prospective cohort studies. Design: We followed 78,012 women in the Nurses' Health Study and 46,695 men in the Health Professionals Follow-up Study from 1986 and 1988, respectively, until 2012. We created dietary index scores for the Dietary Approaches to Stop Hypertension (DASH) diet, Alternative Mediterranean Diet (AMED), and Alternative Healthy Eating Index-2010 (AHEI-2010) and used Cox regression to estimate HRs and 95% CIs for risk of colorectal cancer (CRC) and by anatomic subsite. We also conducted latency analyses to examine associations between diet and CRC risk during different windows of exposure. We conducted analyses in men and women separately, and subsequently pooled these results in a random-effects meta-analysis. Results: We documented 2690 colorectal cancer cases. Pooled multivariable HRs for colorectal cancer risk comparing the highest to lowest quintile of diet scores were 0.89 (95% CI: 0.74, 1.08; P-trend = 0.10) for DASH, 0.89 (95% CI: 0.73, 1.10; P-trend = 0.31) for AMED, and 0.95 (95% CI: 0.83, 1.09; P-trend = 0.56) for AHEI-2010 (P-heterogeneity >= 0.07 for all). In sex-specific analyses, we observed stronger associations in men for all dietary indexes (DASH: multivariable HR = 0.81, 95% CI: 0.66, 0.98; P-trend = 0.003; AMED: multivariable HR = 0.80, 95% CI: 0.65, 0.98; P-trend = 0.02; AHEI-2010: multivariable HR = 0.88, 95% CI: 0.72, 1.07; P-trend = 0.04) than in women (multivariable HRs range from 0.98 to 1.01). Conclusions: Adherence to the DASH, AMED, and AHEI-2010 diets was inversely associated with colorectal cancer risk in men. These diets were not associated with colorectal cancer risk in women.

PMID- 30289435 TI - Phase 1 Safety and Pharmacokinetics Study of MK-2048/Vicriviroc (MK-4176)/MK 2048A Intravaginal Rings. AB - Background: Vaginal rings (VR) containing antiretroviral (ARV) drugs can be utilized for prevention of human immunodeficiency virus (HIV) with potential for improved adherence compared to daily pills. Combination ARV VRs could improve efficacy. Methods: MTN-027, a single-blind, randomized, placebo-controlled trial in 48 women, evaluated VRs containing MK-2048 (30 mg) and vicriviroc (VCV, 182 mg), alone or in combination, and placebo used continuously for 28 days. Safety was assessed by recording adverse events. Drug concentrations were quantified in plasma, vaginal fluid, cervical tissue, and rectal fluid. Cervical tissue was utilized for ex vivo HIV inhibition analysis. Results: There was no difference in related genitourinary adverse events between treatment arms compared to placebo. VCV and MK-2048 released from single or combination VRs both achieved peak concentrations in vaginal fluids, which were substantially higher compared to plasma (200* for VCV, 30* for MK-2048) and rectal fluid. In an ex vivo challenge assay, the antiviral activity of VCV and/or MK-2048 was not correlated with tissue-associated drug concentrations. Most women (77%) were fully adherent to 28 days of continuous VR use and found the VR acceptable. Conclusions: VCV and/or MK 2048 containing VRs were safe and acceptable. Both VCV and MK-2048 were quantifiable in all matrixes tested with peak compartmental drug concentrations similar for single and combination drug VRs. Tissue-associated VCV and/or MK-2048 did not correlate with inhibition of HIV infection. These data highlight the need to assess adequacy of drug dosing in the VR and measuring genital tissue drug concentrations to develop more precise concentration-response relationships.

AB - The purpose of this study is to compare the effect of unpredictable (U) or predictable (P) food delivery on health and longevity in mice. From 2 months of age until end of life, singly-housed male C57BL/6 mice were fed a semisynthetic diet either ad libitum (AL), or as imposed meals delivered as small pellets at either P or U times, frequencies, or amounts. The total daily food consumed by all groups was the same. The AL group gained body weight faster than either P or U groups, and had ~12% shorter median life span compared with either P or U groups. Bimonthly non-invasive body composition determinations showed that the differences in body weights were due to differences in fat and lean mass. Post mortem examinations revealed that the organ pathologies were similar in all groups, but a larger fraction of P and U mice were euthanized due to end-of-life suffering. There were no systematic differences in outcome measures between P and U groups suggesting that, within the range studied, the temporal pattern of food delivery did not have a significant metabolic effect. PMID- 30289439 TI - XY oocytes of sex-reversed females with a Sry mutation deviate from the normal developmental process beyond the mitotic stage. AB - The fertility of sex-reversed XY female mice is severely impaired by a massive loss of oocytes and failure of meiotic progression. This phenomenon remains an outstanding mystery. We sought to determine the molecular etiology of XY oocyte dysfunction by generating sex-reversed females that bear genetic ablation of Sry, a vital sex determination gene, on an inbred C57BL/6 background. These mutant mice, termed XYsry- mutants, showed severe attrition of germ cells during fetal development, resulting in the depletion of ovarian germ cells prior to sexual maturation. Comprehensive transcriptome analyses of primordial germ cells and postnatal oocytes demonstrated that XYsry- females had deviated significantly from normal developmental processes during the stages of mitotic proliferation. The impaired proliferation of XYsry- PGCs was associated with aberrant beta catenin signaling and the excessive expression of transposable elements. Upon entry to the meiotic stage, XYsry- oocytes demonstrated extensive defects, including the impairment of crossover formation, the failure of primordial follicle maintenance, and no capacity for embryo development. Together, these results suggest potential molecular causes for germ cell disruption in sex reversed female mice, thereby providing insights into disorders of sex differentiation in humans, such as "Swyer syndrome," in which patients with an XY karyotype present as typical females and are infertile. PMID- 30289440 TI - Mesenchymal Stem Cells for Periodontal Tissue Regeneration in Elderly Patients. AB - Mesenchymal stem cell (MSC) grafting is a highly promising alternative strategy for periodontal regeneration in periodontitis, which is one of the primary causes of tooth loss in the elderly. However, aging progressively decreases the proliferative and differentiation potential of MSCs and diminishes their regenerative capacity, which represents a limiting factor for their endogenous use in elderly patients. Therefore, tissue regeneration therapy with MSCs in this age group may require a cellular source without the physiological limitations that MSCs exhibit in aging. In this sense, exogenous or allogeneic MSCs could have a better chance of success in regenerating periodontal tissue in elderly patients. This review examines and synthesizes recent data in support of the use of MSCs for periodontal regenerative therapy in patients. Additionally, we analyze the progress of the therapeutic use of exogenous MSCs in humans. PMID- 30289441 TI - Deletion of Adam6 in Mus musculus leads to male subfertility and deficits in sperm ascent into the oviduct. AB - The A disintegrin and metalloprotease domain-containing (ADAM) family of proteins is involved in cell adhesion, migration, proteolysis, and signaling. Many ADAMs are required for reproduction; however, the role of Adam6 has remained largely unknown. In the course of humanizing the mouse immunoglobulin heavy chain (IgH) locus we generated Adam6-deficient mice that demonstrate severe subfertility. We decided to elucidate the role of ADAM6 in fertility and explore the underlying mechanisms. Despite normal sperm development and motility, Adam6-deficient mice display diminished male fertility, have abnormal sperm adhesion, and most importantly cannot transition from uterus to oviduct. To test whether ADAM6 is required for sperm's binding to extracellular matrix components (ECM), we used a panel of ECM components and showed that unlike normal sperm, Adam6-deficient sperm cannot bind fibronectin, laminin, and tenascin. Reintroduction of Adam6 into these deficient mice repaired sperm interaction with ECM, restored male fertility, and corrected the sperm transport deficit. Together our data suggest that ADAM6, either alone or in complex with other proteins, aids sperm transport through the female reproductive tract by providing a temporary site of attachment of sperm to ECM components prior to ascent into the oviduct. PMID- 30289442 TI - Quantifying Waddington's epigenetic landscape: a comparison of single-cell potency measures. AB - MOTIVATION: Estimating differentiation potency of single cells is a task of great biological and clinical significance, as it may allow identification of normal and cancer stem cell phenotypes. However, very few single-cell potency models have been proposed, and their robustness and reliability across independent studies have not yet been fully assessed. RESULTS: Using nine independent single cell RNA-Seq experiments, we here compare four different single-cell potency models to each other, in their ability to discriminate cells that ought to differ in terms of differentiation potency. Two of the potency models approximate potency via network entropy measures that integrate the single-cell RNA-Seq profile of a cell with a protein interaction network. The comparison between the four models reveals that integration of RNA-Seq data with a protein interaction network dramatically improves the robustness and reliability of single-cell potency estimates. We demonstrate that underlying this robustness is a correlation relationship, according to which high differentiation potency is positively associated with overexpression of network hubs. We further show that overexpressed network hubs are strongly enriched for ribosomal mitochondrial proteins, suggesting that their mRNA levels may provide a universal marker of a cell's potency. Thus, this study provides novel systems-biological insight into cellular potency and may provide a foundation for improved models of differentiation potency with far-reaching implications for the discovery of novel stem cell or progenitor cell phenotypes. PMID- 30289443 TI - Human-like layout algorithms for signalling hypergraphs: outlining requirements. AB - The use of signalling pathway hypergraphs represented as process description diagrams is steadily becoming more pervasive in the field of biology. This makes ever more evident the necessity for an effective automated layout that can replicate high-quality manually drawn diagrams. The complexity and idiosyncrasies of these diagrams, as well as the specific tasks the end users perform with them, mean that a layout must meet many requirements beyond the simple metrics used in existing automated computational approaches. In this paper we outline these requirements, examine existing ones and describe new ones. We demonstrate state of-the-art layout techniques enhanced with novel functionalities to meet part of the requirements. For comparatively small signalling pathways our enhanced algorithm provides results close to manually drawn layouts. In addition, we suggest technical approaches that may be suited for fulfilling the identified requirements currently not covered. PMID- 30289444 TI - Phase 1 Pharmacokinetic Trial of 2 Intravaginal Rings Containing Different Dose Strengths of Vicriviroc (MK-4176) and MK-2048. AB - Background: Vaginal rings (VRs) are a promising approach for sustained delivery of antiretroviral (ARV) medication to prevent human immunodeficiency virus (HIV) infection in women. Combination ARV VRs could increase efficacy. Methods: MTN 028, a phase 1 trial in 19 HIV-uninfected women, evaluated 2 VRs containing vicriviroc (VCV) and MK-2048. Participants were randomized 2:1 to a low-dose (VCV, 91 mg; MK-2048, 10 mg) or original-dose (VCV, 182 mg; MK-2048, 30 mg) ring used for 28 days. Safety was assessed by documenting adverse events (AEs). Drug concentrations were evaluated in plasma, cervicovaginal fluid (CVF), and cervical tissue samples. Results: All AEs reported were grade 1 or 2, with no statistically significant differences in related genitourinary AEs or grade >=2 AEs observed between arms (P = >.99). VCV/MK-2048 concentrations rose rapidly, with higher plasma area under the concentration-time curve (AUC) in the original dose arm (geometric mean ratio, 3.29 for VCV and 1.49 for MK-2048) and similar AUCs across arms for CVF samples. Cervical tissue concentrations were higher in the original-dose arm (geometric mean ratio, 7.94 for VCV and 6.45 for MK-2048), with greater drug released based on residual drug levels. Plasma and CVF concentrations for both drugs fell rapidly after ring removal. Conclusions: In this first study evaluating 2 doses of a combination VCV/MK-2048 VR, both rings were found to be safe and well tolerated. VCV and MK-2048 were detectable in plasma, CVF, and cervical tissue samples, and drug release and plasma drug exposure were higher for the original-dose than for the low-dose ring.

PMID- 30289445 TI - Dysregulation of Cortisol Metabolism in Equine Pituitary Pars Intermedia Dysfunction. AB - Equine Cushing disease [pituitary pars intermedia dysfunction (PPID)] is a common condition of older horses, but its pathophysiology is complex and poorly understood. In contrast to pituitary-dependent hyperadrenocorticism in other species, PPID is characterized by elevated plasma ACTH but not elevated plasma cortisol. In this study, we address this paradox and the hypothesis that PPID is a syndrome of ACTH excess in which there is dysregulation of peripheral glucocorticoid metabolism and binding. In 14 horses with PPID compared with 15 healthy controls, we show that in plasma, cortisol levels and cortisol binding to corticosteroid binding globulin were not different; in urine, glucocorticoid and androgen metabolites were increased up to fourfold; in liver, 11beta hydroxysteroid dehydrogenase type 1 (11beta-HSD1) expression was reduced; in perirenal adipose tissue, 11beta-HSD1 and carbonyl reductase 1 expression was increased; and tissue cortisol levels were not measurably different. The combination of normal plasma cortisol with markedly enhanced urinary cortisol metabolite excretion and dysregulated tissue-specific steroid-metabolizing enzymes suggests that cortisol clearance is increased in horses with PPID. We infer that the ACTH excess may be compensatory and pituitary pathology and autonomous secretion may be a secondary rather than primary pathology. It is possible that successful therapy in PPID may be targeted either at lowering ACTH or, paradoxically, at reducing cortisol clearance. PMID- 30289447 TI - Variability in a permanent cyanobacterial bloom: species-specific responses to environmental drivers. AB - Cyanobacterial blooms are characterized by intense growth of one or few species that will dominate the phytoplankton community for periods of few months to an entire year or more. However, even during persistent blooms, important seasonal changes among dominant species can be observed. Pampulha reservoir is a tropical eutrophic reservoir presenting permanent blooms. To identify the main species in this environment, a closer analysis performed by microscopy and 16S-rRNA DGGE revealed Cylindrospermopsis raciborskii as highly dominant throughout the year. The second most abundant group comprised species belonging to the Microcystis genus. They followed a well-defined seasonal pattern described by interesting species-specific ecological trends. During thermal stratification in the rainy/warmer season, C. raciborskii dominated in the water column, while Microcystis spp. were abundant at the end of the dry season, a period characterized by higher total phosphorus concentrations. Phylogenetic analyses confirmed the two dominant taxa and their seasonal trends. The results showed that cyanobacteria major controlling factors were strongly species dependent, shifting from physical/climate related (stratification) to more chemical driven (nutrients/eutrophication). Identifying these drivers is therefore essential for the understanding of the bloom dynamics and the real risks associated with each species, and to eventually adopt the most appropriate and effective management strategies. PMID- 30289449 TI - The screening and identification of the biological control fungi Chaetomium spp. against wheat common root rot. AB - Bipolaris sorokiniana is a soil-borne fungal pathogen causing common root rot in wheat, and is difficult to control through chemical and agricultural means. Chaetomium spp. have been documented as potential biological control agents for plant diseases. In this study, seven Chaetomium strains were screened for their abilities to control B. sorokiniana on agar plates. Strain 22-10 significantly inhibited the growth of B. sorokiniana on potato dextrose agar plates, up to 66.7%. Its filtrate of liquid culture also inhibited the mycelial growth of B. sorokiniana, indicating that strain 22-10 produced secondary metabolites against B. sorokiniana. The incidence and disease indexes of common root rot significantly decreased in wheat after treatment with the crude extract of strain 22-10. Six active compounds were purified from crude extract of this fungus culture against B. sorokiniana. Chaetoviridin A showed the highest efficiency to inhibit the growth of B. sorokiniana. Strain 22-10 was identified as Chaetomium globosum based on phylogenetic analysis of the rDNA internal transcribed spacer region and microscopic characteristics. The high control efficiency of strain 22 10 of C. globosum against B. sorokiniana suggested it has potential to be a biocontrol agent for B. sorokiniana. PMID- 30289448 TI - Prokaryotic communities of Indo-Pacific giant barrel sponges are more strongly influenced by geography than host phylogeny. AB - Sponges harbor complex communities of microorganisms that carry out essential roles for the functioning and survival of their hosts. In some cases, genetically related sponges from different geographic regions share microbes, while in other cases microbial communities are more similar in unrelated sponges collected from the same location. To better understand how geography and host phylogeny cause variation in the prokaryotic community of sponges, we compared the prokaryotic community of 44 giant barrel sponges (Xestospongia spp.). These sponges belonged to six reproductively isolated genetic groups from eight areas throughout the Indo-Pacific region. Using Illumina sequencing, we obtained 440 000 sequences of the 16S rRNA gene V3V4 variable region that were assigned to 3795 operational taxonomic units (OTUs). The prokaryotic community of giant barrel sponges was characterized by 71 core OTUs (i.e. OTUs present in each specimen) that represented 57.5% of the total number of sequences. The relative abundance of these core OTUs varied significantly among samples, and this variation was predominantly related to the geographic origin of the sample. These results show that in giant barrel sponges, the variation in the prokaryotic community is primarily associated with geography as opposed to phylogenetic relatedness. PMID- 30289450 TI - Lack of Vitamin D Receptor Leads to Hyperfunction of Claudin-2 in Intestinal Inflammatory Responses. AB - Background: Vitamin D3 and vitamin D receptor (VDR) are involved in the pathogenesis of inflammatory bowel disease (IBD) and bacterial infection. Claudin 2 is a junction protein that mediates paracellular water transport in epithelia. Elevation of Claudin-2 is associated with active IBD. However, VDR involved in epithelial junctions under inflammation and infection remains largely unknown. We investigated the mechanisms on how VDR and Claudin-2 are related in inflamed states. Methods: Using cultured VDR-/- enteroids, human intestinal epithelial cells, VDR-/- mice with Salmonella- or DSS-colitis, and human IBD samples, we investigated the mechanisms how VDR and Claudin-2 are related in inflamed states. Results: After Salmonella infection had taken place, we observed significantly enhanced Claudin-2 and an increased bacterial invasion and translocation. A lack of VDR regulation led to a robust increase of Claudin-2 at the mRNA and protein levels post-infection. In DSS-treated VDR-/- mice, Claudin-2 was significantly increased. Location and quantification of Claudin-2 protein in the mouse colons treated with DSS also confirmed these results. Inflammatory cytokines were significantly higher in the serum and mRNA levels in intestine, which are known to increase Claudin-2. Furthermore, in inflamed intestine of ulcerative colitis patients, VDR expression was low and Claudin-2 was enhanced. Mechanistically, we identified the enhanced Claudin-2 promoter activity through the binding sites of NF-kappaB and STAT in inflamed VDR-/- cells. Conclusions: Our studies have identified a new role for intestinal epithelial VDR in regulating barrier functions in the context of infection and inflammation.

AB - Monoclonal antibodies (mAbs) are currently the largest and fastest growing class of biopharmaceuticals, and they address unmet medical needs e.g., in oncology and in auto-immune diseases. Their clinical efficacy and safety is significantly affected by the structure and composition of their glycosylation profile which is commonly heterogeneous, heavily dependent on the manufacturing process, and thus susceptible to variations in the cell culture conditions. Glycosylation is therefore considered a critical quality attribute (CQA) for mAbs. Commonly, in currently marketed therapeutic mAbs, the glycosylation profile is suboptimal in terms of biological properties such as antibody-dependent cell-mediated cytotoxicity (ADCC) or may give rise to safety concerns due to the presence of non-human glycans.This article will review recent innovative developments in chemo-enzymatic glycoengineering, which allow generating mAbs carrying single, well-defined, uniform Fc glycoforms, which confers the desired biological properties for the target application. This approach offers significant benefits such as enhanced Fc effector functions, improved safety profiles, higher batch-to batch consistency, decreased risks related to immunogenicity and manufacturing process changes, and the possibility to manufacture mAbs, in an economical manner, in non-mammalian expression systems. Overall, this approach could facilitate and reduce mAb manufacturing costs which in turn would translate into tangible benefits for both patients and manufacturers. The first glycoengineered mAbs are about to enter clinical trials and it is expected that, once glycoengineering reagents are available at affordable costs, and in-line with regulatory requirements, that targeted remodelling of antibody Fc glycosylation will become an integral part in manufacturing the next-generation of immunotherapeutics. PMID- 30289454 TI - Dusp6 is a genetic modifier of growth through enhanced ERK activity. AB - Like other single gene disorders, muscular dystrophy displays a range of phenotypic heterogeneity even with the same primary mutation. Identifying genetic modifiers capable of altering the course of muscular dystrophy is one approach to deciphering gene-gene interactions that can be exploited for therapy development. To this end, we used an intercross strategy in mice to map modifiers of muscular dystrophy. We interrogated genes of interest in an interval on mouse chromosome 10 associated with body mass in muscular dystrophy as skeletal muscle contributes significantly to total body mass. Using whole genome sequencing of the two parental mouse strains combined with deep RNA sequencing, we identified the Met62Ile substitution in the Dusp6 gene from the DBA/2J mouse strain. DUSP6 is a broadly expressed dual specificity phosphatase protein, which binds and dephosphorylates ERK, leading to decreased ERK activity. We found that the Met62Ile substitution reduced the interaction between DUSP6 and ERK resulting in increased ERK phosphorylation and ERK activity. In dystrophic muscle, DUSP6 Met62Ile is strongly upregulated to counteract its reduced activity. We found that myoblasts from the DBA/2J background were insensitive to a specific small molecule inhibitor of DUSP6, while myoblasts expressing the canonical DUSP6 displayed enhanced proliferation after exposure to DUSP6 inhibition. These data identify DUSP6 as an important regulator of ERK activity in the setting of muscle growth and muscular dystrophy. PMID- 30289455 TI - DNA phosphorothioate modification - a new multi-functional epigenetic system in bacteria. AB - Synthetic phosphorothioate (PT) internucleotide linkages, in which a nonbridging oxygen is replaced by a sulfur atom, share similar physical and chemical properties with phosphodiesters but confer enhanced nuclease tolerance on DNA/RNA, making PTs a valuable biochemical and pharmacological tool. Interestingly, PT modification was recently found to occur naturally in bacteria in a sequence-selective and RP configuration-specific manner. This oxygen-sulfur swap is catalysed by the gene products of dndABCDE, which constitute a defence barrier with DndFGH in some bacterial strains that can distinguish and attack non PT-modified foreign DNA, resembling DNA methylation-based restriction modification (R-M) systems. Despite their similar defensive mechanisms, PT- and methylation-based R-M systems have evolved to target different consensus contexts in the host cell because when they share the same recognition sequences, the protective function of each can be impeded. The redox and nucleophilic properties of PT sulfur render PT modification a versatile player in the maintenance of cellular redox homeostasis, epigenetic regulation and environmental fitness. The widespread presence of dnd systems is considered a consequence of extensive horizontal gene transfer, whereas the lability of PT during oxidative stress and the susceptibility of PT to PT-dependent endonucleases provide possible explanations for the ubiquitous but sporadic distribution of PT modification in the bacterial world.

Using problem-based learning to test the 5-second rule and promote scientific literacy. AB - Defining appropriate student learning outcomes for general education science courses is a daunting task. We must ask ourselves how to best prepare our students to understand the role of science in their lives and in society at large. In the era of social media and armchair experts, life-changing scientific advancements such as vaccination are being dismissed or actively resisted, emphasizing the critical need to teach science literacy skills. One active classroom method known as problem-based learning promotes self-motivated learning and synthesis skills that, when applied in a science-literacy context, can provide students with the ability to generate informed opinions on new scientific advances throughout their lifetime. This piece describes one such problem-based course, designed to tackle the scientific basis (or lack thereof) of the 5-second rule for eating food dropped on the floor. In this course, first year students experimentally engage this issue, while also applying their developing skill set to sort out scientific controversies such as vaccine safety and genetically modified foods.

PMID- 30289459 TI - Helicobacter pylori induces intracellular galectin-8 aggregation around damaged lysosomes within gastric epithelial cells in a host O-glycan-dependent manner. AB - Galectin-8, a beta-galactoside-binding lectin, is upregulated in the gastric tissues of rhesus macaques infected with Helicobacter pylori. In this study, we found that H. pylori infection triggers intracellular galectin-8 aggregation in human-derived AGS gastric epithelial cells, and that these aggregates colocalize with lysosomes. Notably, this aggregation is markedly reduced following the attenuation of host O-glycan processing. This indicates that H. pylori infection induces lysosomal damage, which in turn results in the accumulation of cytosolic galectin-8 around damaged lysosomes through the recognition of exposed vacuolar host O-glycans. H. pylori-induced galectin-8 aggregates also colocalize with autophagosomes, and galectin-8 ablation reduces the activation of autophagy by H. pylori. This suggests that galectin-8 aggregates may enhance autophagy activity in infected cells. We also observed that both autophagy and NDP52, an autophagy adaptor, contribute to the augmentation of galectin-8 aggregation by H. pylori. Additionally, vacuolating cytotoxin A, a secreted H. pylori cytotoxin, may contribute to the increased galectin-8 aggregation and elevated autophagy response in infected cells. Collectively, these results suggest that H. pylori promotes intracellular galectin-8 aggregation, and that galectin-8 aggregation and autophagy may reciprocally regulate each other during infection. PMID- 30289460 TI - An Adjuvant That Increases Protective Antibody Responses to Polysaccharide Antigens and Enables Recall Responses. AB - Protection against encapsulated bacteria can be elicited using polysaccharide vaccines. These antigens often behave as T-cell-independent type 2 antigens (TI-2 Ags). However, TI-2 Ags, including pneumococcal polysaccharides, often elicit weak immunoglobulin G (IgG) responses and are refractive to boosting. Conjugate vaccines have not completely overcome this challenge and hence, alternative strategies are required to enhance polysaccharide vaccine responses. Herein, we describe an adjuvant consisting of a Toll-like receptor and C-type lectin receptor agonist pairing that significantly increases primary immunoglobulin M and IgG responses to TI-2 Ags as well as enables significant boosting when coadministered with polysaccharide vaccines. Consistent with this, the adjuvant significantly increased the generation of both TI-2 memory B cells and long-lived antibody secreting cells. Adjuvant effects were highly dependent on B-cell intrinsic MyD88, but not Trif expression. Importantly, coadministration of the adjuvant with the Pneumovax vaccine significantly increased the protective efficacy of vaccination in a lethal challenge mouse model of pneumococcal respiratory infection. Collectively, these data provide evidence that B-cell directed adjuvants have promise in significantly improving the quality and quantity of serologic and B-cell memory responses to clinically relevant polysaccharide vaccines. PMID- 30289461 TI - Environmental health in Australia: overlooked and underrated. AB - Improvements in environmental health have had the most significant impact on health status. In Australia, life expectancy has significantly increased through provision of vaccination, safe food and drinking water, appropriate sewage disposal and other environmental health measures. Yet the profession that is instrumental in delivering environmental health services at the local community level is overlooked. Rarely featuring in mainstream media, the successes of Environmental Health Officers (EHOs) are invisible to the general public. As a consequence, students entering university are unaware of the profession and its significant role in society. This has resulted in there being too few EHOs to meet the current regulatory requirements, much less deal with the emerging environmental health issues arising as a consequence of changing global conditions including climate change. To futureproof Australian society and public health this workforce issue, and the associated oversight of environmental health must be addressed now.

AB - The Transphlebotomus subgenus has been drawing attention in last decade due to the uncertain vector capacity and cryptic life history of the group. During a 2015 entomological survey, Phlebotomine flies were collected in western locations of Slovenia, with a total of 22 specimens of the Transphlebotomus subgenus collected. In addition to morphological identifications, we confirmed the presence of Phlebotomus mascittii Grassi, 1908 (Diptera: Psychodidae) by nucleotide sequences of the mitochondrial cytochrome b gene. During the study, we found that P. mascittii is most abundant in the area of coastal-karst region of Slovenia, while in rare occasions can also be collected in Northeastern part of the country, near the Austrian border. Vector competence of P. mascitii, like all other member species of the Transphlebotomus subgenus, is unclear, but potential to transmit Leishmania (Kinetoplastida: Trypanosomatidae) pathogens or phleboviruses is strongly suspected.

AB - Large synthetic genetic circuits require the simultaneous expression of many regulators. Deactivated Cas9 (dCas9) can serve as a repressor by having a small guide RNA (sgRNA) direct it to bind a promoter. The programmability and specificity of RNA:DNA basepairing simplifies the generation of many orthogonal sgRNAs that, in theory, could serve as a large set of regulators in a circuit. However, dCas9 is toxic in many bacteria, thus limiting how high it can be expressed, and low concentrations are quickly sequestered by multiple sgRNAs. Here, we construct a non-toxic version of dCas9 by eliminating PAM (protospacer adjacent motif) binding with a R1335K mutation (dCas9*) and recovering DNA binding by fusing it to the PhlF repressor (dCas9*_PhlF). Both the 30 bp PhlF operator and 20 bp sgRNA binding site are required to repress a promoter. The larger region required for recognition mitigates toxicity in Escherichia coli, allowing up to 9600 +/- 800 molecules of dCas9*_PhlF per cell before growth or morphology are impacted, as compared to 530 +/- 40 molecules of dCas9. Further, PhlF multimerization leads to an increase in average cooperativity from n = 0.9 (dCas9) to 1.6 (dCas9*_PhlF). A set of 30 orthogonal sgRNA-promoter pairs are characterized as NOT gates; however, the simultaneous use of multiple sgRNAs leads to a monotonic decline in repression and after 15 are co-expressed the dynamic range is <10-fold. This work introduces a non-toxic variant of dCas9, critical for its use in applications in metabolic engineering and synthetic biology, and exposes a limitation in the number of regulators that can be used in one cell when they rely on a shared resource. PMID- 30289464 TI - The antimicrobial photodynamic inactivation resistance of Candida albicans is modulated by the Hog1 pathway and the Cap1 transcription factor. AB - Candida albicans is the most important fungal pathogen afflicting humans, particularly immunocompromised patients. However, currently available antifungal drugs are limited and ineffective against drug-resistant strains. The development of new drugs or alternative therapeutic approaches to control fungal infections is urgent and necessary. Photodynamic inactivation (PDI) is a new promising therapy for eradicating microorganism infections through combining visible light, photosensitizers, and oxygen to generate reactive oxygen species (ROS). Although cytoprotective responses induced by photodynamic therapy (PDT) have been well studied in cancer cells, the mechanisms by which C. albicans responds to PDI are largely unknown. In this study, we first demonstrated that PDI induces C. albicans Hog1p activation. Deletion of any of the SSK2, PBS2, and HOG1 genes significantly decreased the survival rate after photochemical reactions, indicating that the Hog1 SAPK pathway is required for tolerance to PDI. Furthermore, the basic leucine zipper transcription factor Cap1 that regulates several downstream antioxidant genes was highly expressed during the response to PDI, and loss of CAP1 also resulted in decreased C. albicans survival rates. This study demonstrates the importance of the Hog1 SAPK and the Cap1 transcription factor, which regulates in resistance to PDI-mediated oxidative stress in C. albicans. Understanding the mechanisms by which C. albicans responds to PDI and consequently scavenges ROS will be very useful for the further development of therapeutics to control fungal infectious diseases, particularly those of the skin and mucosal infections. PMID- 30289466 TI - Health and mass unemployment events-developing a framework for preparedness and response. AB - Background: Mass unemployment events are not uncommon yet the impact on health is not well recognised. There is a need for a preparedness and response framework, as exists for other events that threaten population health. Methods: Framework informed by a narrative review of the impact of mass unemployment on health (studies published in English from 1990 to 2016), and qualitative data from 23 semi-structured interviews with individuals connected to historical national and international events, addressing gaps in published literature on lessons learnt from past responses. Results: Economic and employment shock triggered by mass unemployment events have a detrimental impact on workers, families and communities. We present a public health informed response framework which includes (i) identify areas at risk, (ii) develop an early warning system, (iii) mobilise multi-sector action including health and community, (iv) provision of support across employment, finance and health (v) proportionate to need, (vi) extend support to family members and (vii) communities and (viii) evaluate and learn. Conclusion: Mass unemployment events have an adverse impact on the health, financial and social circumstances of workers, families, and communities. This is the first framework for action to mitigate and address the detrimental impact of mass unemployment events on population health. PMID- 30289467 TI - A prospective survey of Aspergillus spp. in respiratory tract samples: Species identification and susceptibility patterns. AB - We analyzed the species distribution and susceptibility patterns of 433 strains of Aspergillus spp. isolated from respiratory samples of 419 in-patients included in multicenter prospective study (FUNGAE-IFI) between July 2014 and October 2015. Identification was carried out by conventional methods at each participating center and by molecular sequencing of a portion of the beta-tubulin gene at one of the centers. In vitro susceptibility was evaluated by broth microdilution methods and using the E-test (for cryptic species). Species identified included 249 A. fumigatus sensu stricto, 60 A. terreus sensu stricto, 47 A. flavus sensu stricto, 44 A. tubingensis, 18 A. niger sensu stricto , five A. nidulans sensu stricto, three A. tamarii, two A. calidoustus, two A. carneus, one A. acuelatus, one A. carbonarius, and one A. sydowii. Cryptic species were found in 12.5% of isolates (n = 54). The frequency of non-wild-type isolates for amphotericin B was 3.4% (n = 15) of the isolates tested and for azoles 3% (n = 10). None of the Aspergillus spp. were non-wild type to echinocandins. Of the 54 cryptic species only two strains were non-wild-type strains by microdilution method (3.7%) (two A. tubingensis, one to amphotericin B and another one to voriconazole) and by E test method five strains of A. tubingensis showed high minimal inhibitory concentration (MIC) to amphotericin B (11.4%) and five to azoles (12.1%), one A. calidoustus strain showed high MICs for three azoles (50%), A. carneus to itraconazole (100%) and A. sydowii to amphotericin B and itraconazole (100%). These results provide relevant information on susceptibility patterns, frequency, and epidemiology of species involved in respiratory tract samples and of the incidence of recently described cryptic species. PMID- 30289470 TI - Knock-out IFNL4 gene variant is associated with protection from sexually transmitted HIV-1 infection. AB - The IFNL4 knock-out allele (rs368234815-TT) is associated with spontaneous and IFNA-dependent cure of HCV. The role of this polymorphism in susceptibility to HIV-1 infection is controversial. This study is aimed to assess the association of this knock-out IFNL4 gene variant and sexually transmitted HIV-1 infection. 228 HIV-1 positive and 136 HIV-exposed seronegatives were investigated for their association with IFNL4 rs368234815 genotypes. The IFNL4 ?G functional allele is associated to increased susceptibility to HIV-1 infection through sexual route OR: 2.1 95% CI (1.2-3.6), P=0.004. A meta-analysis including an IDU population suggests a codominant mode of inheritance of this risk factor OR: 2.0 95% CI (1.3 3.2), P=0.001.

PMID- 30289469 TI - Oxidative damage to epigenetically methylated sites affects DNA stability, dynamics and enzymatic demethylation. AB - DNA damage can affect various regulatory elements of the genome, with the consequences for DNA structure, dynamics, and interaction with proteins remaining largely unexplored. We used solution NMR spectroscopy, restrained and free molecular dynamics to obtain the structures and investigate dominant motions for a set of DNA duplexes containing CpG sites permuted with combinations of 5 methylcytosine (mC), the primary epigenetic base, and 8-oxoguanine (oxoG), an abundant DNA lesion. Guanine oxidation significantly changed the motion in both hemimethylated and fully methylated DNA, increased base pair breathing, induced BI->BII transition in the backbone 3' to the oxoG and reduced the variability of shift and tilt helical parameters. UV melting experiments corroborated the NMR and molecular dynamics results, showing significant destabilization of all methylated contexts by oxoG. Notably, some dynamic and thermodynamic effects were not additive in the fully methylated oxidized CpG, indicating that the introduced modifications interact with each other. Finally, we show that the presence of oxoG biases the recognition of methylated CpG dinucleotides by ROS1, a plant enzyme involved in epigenetic DNA demethylation, in favor of the oxidized DNA strand. Thus, the conformational and dynamic effects of spurious DNA oxidation in the regulatory CpG dinucleotide can have far-reaching biological consequences.

AB - Structural valve deterioration is a well-studied phenomenon in bioprosthetic heart valves. Conversely, structural valve deterioration after transcatheter aortic valve implantation is not as well-elucidated. Therefore, late surgical explantation after transcatheter aortic valve implantation is an infrequent procedure, and thus, surgical findings and management of such cases remain unclear, particularly in patients previously labelled as 'inoperable' or at 'high risk'. Herein, we report the case of a late surgical explantation of a transcatheter heart valve (THV) 7 years after its implantation in a patient with a porcelain aorta and periprosthetic regurgitation.

PMID- 30289472 TI - Genomic Analyses of Human European Diversity at the Southwestern Edge: Isolation, African Influence and Disease Associations in the Canary Islands. AB - Despite the genetic resemblance of Canary Islanders to other southern European populations, their geographical isolation and the historical admixture of aborigines (from North Africa) with sub-Saharan Africans and Europeans have shaped a distinctive genetic makeup that likely affects disease susceptibility and health disparities. Based on single nucleotide polymorphism array data and whole genome sequencing (30*), we inferred that the last African admixture took place ~14 generations ago and estimated that up to 34% of the Canary Islander genome is of recent African descent. The length of regions in homozygosis and the ancestry-related mosaic organization of the Canary Islander genome support the view that isolation has been strongest on the two smallest islands. Furthermore, several genomic regions showed significant and large deviations in African or European ancestry and were significantly enriched in genes involved in prevalent diseases in this community, such as diabetes, asthma, and allergy. The most prominent of these regions were located near LCT and the HLA, two well-known targets of selection, at which 40-50% of the Canarian genome is of recent African descent according to our estimates. Putative selective signals were also identified in these regions near the SLC6A11-SLC6A1, KCNMB2, and PCDH20-PCDH9 genes. Taken together, our findings provide solid evidence of a significant recent African admixture, population isolation, and adaptation in this part of Europe, with the favoring of African alleles in some chromosome regions. These findings may have medical implications for populations of recent African ancestry. PMID- 30289476 TI - Long-term stability of curve of Spee levelled with continuous archwires in subjects with different vertical patterns: a retrospective study. AB - Objectives: The aim of the study was to evaluate the curve of Spee (COS) stability in patients treated with continuous archwires with different vertical patterns. Methods: The study sample consisted of 60 patients (28 males, 32 females; mean age 19.8 +/- 1.4 years) presenting with COS depth of at least2 mm at baseline. For each subject, lateral cephalograms and dental casts were available before treatment (T1), at the end of orthodontic therapy (T2), and 2 years after the end of treatment (T3). All subjects were divided into three groups according to vertical facial patterns. Cephalometric parameters were used to evaluate the dental movements after treatment. COS depth was measured on digital casts. Mean differences between vertical facial subgroups were contrasted by means of analysis of variance test (P < 0.01). Results: In low-angle subjects, COS levelling occurred through advancement and intrusion of lower incisors, whereas in high-angle patients, the COS was flattened through extrusion and uprighting of lower posterior teeth. In the low-angle group, a significant relapse of lower incisors inclination was observed. Differently, the high-angle group exhibited a greater stability of COS obtained by stable extrusion of posterior teeth. Conclusions: The long-term instability of flared incisors determined the relapse of overbite and COS depth in the low-angle group. PMID- 30289477 TI - RRSP and RID Effector Domains Dominate Virulence Impact of Vibrio vulnificus MARTX Toxin. AB - Background: The bacterial pathogen Vibrio vulnificus causes severe septic foodborne infections. The multifunctional autoprocessing repeats-in-toxins (MARTX) toxin is an important secreted virulence factor. The effector domain region is essential for lethal intestinal infection in mice, but the contribution of each of the five effector domains to infection has not been investigated. Methods: V. vulnificus mutants with varying effector domain content were inoculated intragastrically to mice and time-to-death was monitored to establish the contribution of each effector domain to overall virulence. Each strain was also tested for bacterial dissemination from the intestine to internal organs and for inhibition of phagocytosis. Results: The effector domain region was required for V. vulnificus to inhibit phagocytosis by J774 macrophages, but no single effector domain was required. No single MARTX effector domain was necessary for bacterial dissemination. Nonetheless, overall survival of infected mice did differ dependent upon the infecting V. vulnificus strain. Removal of rid or rrsp significantly reduced V. vulnificus virulence potential, while deletion of duf1 or abh accelerated time to death. Conclusion: RID and RRSP each exert greater effects on virulence compared to other MARTX domains suggesting that modulation of Rho/Ras family GTPases is a critical function of the toxin during intestinal infection. PMID- 30289478 TI - Isavuconazole versus Caspofungin in the Treatment of Candidemia and Other Invasive Candida Infections: The ACTIVE Trial. AB - Background: Isavuconazole was compared to caspofungin followed by oral voriconazole in a phase 3, randomized, double-blind, multinational clinical trial (ACTIVE; NCT00413218) for primary treatment of patients with candidemia or invasive candidiasis. Methods: Adult patients were randomized 1:1 to isavuconazole (200 mg IV TID for 2 days, followed by 200 mg IV QD) or caspofungin (70 mg IV QD on day 1, followed by 50 mg IV QD [70 mg in patients >80 kg]) for a maximum of 56 days. After day 10, patients could switch to oral isavuconazole (isavuconazole arm) or voriconazole (caspofungin arm). The primary efficacy endpoint was successful overall response at end of IV therapy (EOIVT) in patients with proven infection who received >=1 dose of study drug (modified-intent-to treat [mITT] population). The pre-specified noninferiority margin was 15%. Secondary outcomes (mITT) were successful overall response at 2 weeks after end of treatment, all-cause mortality at days 14 and 56, and safety. Results: Of 450 patients randomized, 400 comprised the mITT population. Baseline characteristics were balanced between groups. Successful overall response at EOIVT was observed in 60.3% of patients in the isavuconazole arm, and 71.1% in the caspofungin arm, (adjusted difference [95% confidence interval] -10.8 [-19.9, -1.8]). The secondary endpoints, all-cause mortality, and safety were similar between arms, while median time to clearance of the bloodstream was comparable in both groups. Conclusions: This study did not demonstrate the non-inferiority of isavuconazole to caspofungin for primary treatment of invasive candidiasis. Secondary endpoints were similar between both groups. PMID- 30289479 TI - Prevalence of venous thromboembolism after lung surgery in China: a single centre, prospective cohort study involving patients undergoing lung resections without perioperative venous thromboembolism prophylaxis. AB - OBJECTIVES: Venous thromboembolism (VTE) is a common postoperative complication. Previous studies have shown that the incidence of VTE after major thoracic surgery ranges from 2.3% to 15%. However, there have been no such data from China so far. To evaluate the incidence of postoperative VTE, we conducted a single centre, prospective cohort study. METHODS: Patients who underwent lung resections between July 2016 and March 2017 were enrolled in this study. None of the patients received any prophylaxis perioperatively. All patients were screened for deep venous thrombosis (DVT) using non-invasive duplex lower-extremity ultrasonography 30 days before surgery and within 30 days after surgery and before discharge. Chest tomography, pulmonary embolism protocol was carried out if patients had one of the following conditions: (i) typical symptoms of pulmonary embolism, (ii) high Caprini score (>=9 points) and (iii) newly diagnosed postoperative DVT. RESULTS: Two hundred and sixty-two patients undergoing lung surgery were enrolled, including 115 benign and 147 malignant disease cases. The procedures included 84 sublobar lung resections, 161 lobectomies, 5 pneumonectomies and 12 mixed procedures. The overall postoperative incidence of VTE was 11.5% (30 of 262). Twenty-four patients were diagnosed with DVT (80.0%) and 6 with DVT + pulmonary embolism (20.0%). None of the patients diagnosed with VTE had obvious symptoms of VTE. The median time for VTE detection was 5 days postoperatively. The incidence of VTE was 7.0% in patients with benign lung diseases and 15.0% in those with malignant lung diseases (P < 0.05). Using the Caprini risk assessment model, 63 cases were scored as low risk, 179 as moderate risk and 20 as high risk, and each group had an incidence of postoperative VTE of 0%, 12.3% (22 of 179) and 40.0% (8 of 20), respectively (P < 0.05). In patients with lung cancer, 98% were moderate or high risk, and only 3 patients were scored in the low risk category. The incidence of VTE in patients at moderate risk and high risk was 12.0% and 36.8%, respectively, while it was 0 in low-risk patients. CONCLUSIONS: The following conclusions were drawn: (i) the overall incidence of postoperative VTE after lung surgery without VTE prophylaxis is substantial; (ii) lower-extremity ultrasonography was helpful in detecting asymptomatic DVT in symptomatic or high-risk patients; and (iii) VTE prophylaxis should be considered as a mandatory part of perioperative care.

AB - OBJECTIVES: Depletion in skeletal muscle is closely associated with limited physical ability and high mortality. In this study, we evaluated the prognostic significance of skeletal muscle depletion in patients with early-stage non-small cell lung cancer. METHODS: A retrospective analysis of patients with pathological stages I-II lung cancer, who underwent curative resection between 2009 and 2013, was conducted. The truncal muscle index (TMI) (area/height2) at the first lumbar vertebral level was measured by preoperative axial computed tomography. Overall survival and recurrence-free survival were compared between the lowest gender specific quartile of the TMI and the other quartiles. RESULTS: A total of 314 subjects were included in the study. The cumulative 5-year recurrence-free and overall survival rates were significantly shorter in patients with lower TMIs (69% vs 83.5%, P = 0.028; 64.8% vs 80.1%, P = 0.003, respectively). In multivariable models, the TMI was identified as an independent prognostic factor for overall survival (P = 0.017, hazard ratio 1.84, 95% confidence interval 1.12 3.05), after adjusting for age, gender, preoperative serum albumin, carcinoembryonic antigen, neutrophil to lymphocyte ratio and pathological stage. CONCLUSIONS: A low preoperative TMI was associated with a poor postoperative outcome in patients with early-stage non-small-cell lung cancer. This factor may be included in the preoperative assessment of patients, for whom surgical intervention is considered.

AB - Background: Postmenopausal women have unique sociobiological human immunodeficiency virus (HIV) risks. We evaluated the safety, pharmacokinetics, and acceptability of a microbicide dapivirine (DPV) vaginal ring (VR) versus placebo in postmenopausal women. Methods: We enrolled 96 HIV-negative postmenopausal US women in a phase 2a double-blind, randomized (3:1) trial of monthly VRs containing 25 mg DPV or placebo used continuously for 12 weeks. We assessed safety by adverse events (AEs). DPV concentrations were quantified in plasma and vaginal fluid. Steady-state concentrations were analyzed at 4, 8, and 12 weeks using repeated measures ANOVA. We assessed acceptability by self-report. Results: We found no differences in the proportion of women with related grade 2 or higher reproductive system AEs (DPV: 6/72 (8%), placebo: 3/24 (13%), P = .68) or grade 3 or higher AEs (DPV: 4/72 (6%), placebo: 0/24 (0%), P = .57). In the DPV arm, 2/72 (3%) declined to resume product use due to AEs. Median DPV concentrations in plasma (262.0 pg/mL at week 12) and vaginal fluid (40.6 ng/mg at week 12) were constant over 12 weeks and exceeded the in vitro 50% effective concentration by 5000-fold in vaginal fluid by week 4. VR acceptability was high; 84/93 (90%) "very much liked or liked" the VR. Conclusions: DPV VRs were safe, well tolerated, and acceptable in postmenopausal women. Plasma concentrations were comparable to published data on DPV use in reproductive-age women (median plasma concentration: 264 pg/mL). Given the reassuring safety and pharmacokinetic data, the DPV VR is promising for preexposure prophylaxis in postmenopausal women.

AB - The possible presence of Pneumocystis in a bronchoscopy unit of a tertiary hospital was examined by detecting Pneumocystis-specific DNA by polymerase chain reaction in prospectively obtained samples of oropharyngeal wash from seven healthcare workers (HCWs) and air from three areas of the unit at different time points (baseline, days +15,+30,+60,+90 after initiation of the study). Positive samples were genotyped at two genetic loci: the mitochondrial large subunit ribosomal RNA (mtLSUrRNA) fragment by direct sequencing and the gene for dihydropteroate synthase (DHPS) by restriction fragment-length polymorphism. Pneumocystis DNA was identified in 13/24 samples from HCWs, in 4/14 air samples and also in two patients with Pneumocystis pneumonia (PcP) and another with a Pneumocystis-associated disease subjected to bronchoscopy on days +15 and +60 after initiation of the study. The HCWs harbored a high rate of mtLSU-rRNA genotypes 1 and 3 and samples from air and patients with only genotype 3. DHPS mutations related to sulpha resistance were detected in three samples from HCWs and in one from air; 65% of the positive samples showed genotypic concordance. The study demonstrates that HCWs of bronchoscopy units represent a new dynamic reservoir and a possible source of infection for human Pneumocystis species, including DHPS genotypes related to sulpha resistance that could be transmitted within hospitals to immunosuppressed hosts in whom a PcP can develop. The results provide the first evidence of the risk of Pneumocystis transmission in the bronchoscopy units and arguments to improve prevention and control of this infection in nosocomial setting. PMID- 30289487 TI - The NTP binding site of the polymerase ribozyme. AB - A previously developed RNA polymerase ribozyme uses nucleoside triphosphates (NTPs) to extend a primer 3'-terminus, templated by an RNA template with good fidelity, forming 3'-5'-phosphordiester bonds. Indirect evidence has suggested that the ribozyme's accessory domain binds the NTP with a highly conserved purine rich loop. To determine the NTP binding site more precisely we evolved the ribozyme for efficient use of 6-thio guanosine triphosphate (6sGTP). 6sGTP never appeared in the evolutionary history of the ribozyme, therefore it was expected that mutations would appear at the NTP binding site, adapting to more efficient binding of 6sGTP. Indeed, the evolution identified three mutations that mediate 200-fold improved incorporation kinetics for 6sGTP. A >50-fold effect resulted from mutation A156U in the purine-rich loop, identifying the NTP binding site. This mutation acted weakly cooperative with two other beneficial mutations, C113U in the P2 stem near the catalytic site, and C79U on the surface of the catalytic domain. The preference pattern of the ribozyme for different NTPs changed when position 156 was mutated, confirming a direct contact between position 156 and the NTP. The results suggest that A156 stabilizes the NTP in the active site by a hydrogen bond to the Hoogsteen face of the NTP. PMID- 30289488 TI - Effect of hydrocolloids on the quality of restructured hams with duck skin. AB - We investigated the quality of duck ham restructured with various hydrocolloids (Alginic acid, Konjac, Carrageenan) on proximate composition, cooking loss, emulsion stability, pH, color, texture profile analysis (TPA), protein solubility, sensory characteristics, and apparent viscosity. Restructured duck ham was prepared as follows: control with no hydrocolloids, T1 (Alginate 1%), T2 (Alginate 0.5% + Konjac 0.5%), T3 (Alginate 0.7% + Konjac 0.3%), T4 (Alginate 0.5% + Carrageenan 0.5%), and T5 (Alginate 0.7% + Carrageenan 0.3%). The restructured duck hams with hydrocolloids had higher value for moisture content, ash content, and apparent viscosity than the control (P < 0.05). The cooking loss, total expressible fluid and fat separation, redness, hardness, cohesiveness, gumminess, and chewiness of restructured duck hams with hydrocolloids was lower than those of the control (P < 0.05). The sensory score for overall acceptability of restructured duck ham with T1 (1% alginate) and T2 (0.5% alginate + 0.5% konjac) was higher than that of the control (P < 0.05). Thus, this study showed that adding 1% alginate or 0.5% alginate + 0.5% konjac in restructured duck ham formulations results in optimized quality characteristics. PMID- 30289489 TI - The Effect of Negative Aging Self-Stereotypes on Satisfaction With Social Support. AB - Objectives: Previous studies have demonstrated a relationship between negative age self-stereotypes and social support satisfaction. This study examined whether negative age stereotype plays a causal role, and whether health anxiety is a possible mediator, in this relationship. Methods: A total of 114 Chinese older persons were randomly assigned into three experimental conditions. In two of the conditions, participants were primed with either negative or positive age stereotypes using a sentence unscrambling task, before responding to measures of self-perception of aging, health anxiety, and satisfaction with family and nonfamily support. Those in the control condition responded to the same questions without priming. Results: Main effects of priming were found across the board except for satisfaction with nonfamily support. In general, participants primed with negative age stereotypes reported more negative self-perception of aging, higher health anxiety, and lower satisfaction with family support, compared with control or those primed with positive age stereotypes. However, the effect on family support satisfaction could not be explained by concomitant experimental effect on health anxiety. Discussion: The central role of the family as a support provider might be the reason why the activation of negative age stereotypes led to less satisfaction with family, but not nonfamily.

AB - The emerging 5 G wireless devices working at frequencies above 6 GHz are expected to have antenna arrays formed by dipoles, slots, patches or their combination. At lower frequencies, the accepted criteria for exposure compliance is stated in terms of specific absorption rate. IEEE and ICNIRP are adopting epithelial or transmitted power density (PD through body surface) as the dosimetric reference for frequencies above 6 GHz, which entails the measurement of free space PD. Theoretical and numerical results presented in this article show that it is possible to perform meaningful free space PD assessments at half wave (lambda/2) distance from arrays and, with the proper instrumentation, as close as lambda/(2pi). However, if a dissipative body is placed very close (= 5 years of PTDM were included from a cohort of 895 kidney recipients transplanted in 2000-2011. Diabetic retinopathy was evaluated by fundus photographs and optical coherence tomography (OCT). Diabetes kidney disease was evaluated by protein to creatinine ratio (PCR) and estimated glomerular filtration rate (eGFR). Distal polyneuropathy was assessed by Michigan Protocol and 10 g-monofilament feet exams. The Ewing protocol identified cardiovascular autonomic neuropathy. Renal transplant recipients without PTDM diagnosis (NPTDM) were considered controls. Results: After 144.5 months of follow-up, 135 (15%) patients developed PTDM, and 64 had a PTDM duration >= 5 years. None of PTDM patients presented diabetic retinopathy at fundus photographs but thinning of inner retinal layers was observed with OCT. More than 60% of PTDM patients had distal polyneuropathy (OR 1.55; CI 1.26-1.91; p<0.001). Cardiovascular reflex tests abnormalities were similar between PTDM and NPTDM patients (p=0.26). During the 1st year and after 8.5+/-3.0 years of renal transplantation, eGFR and PCR did not differ significantly between patients with and without PTDM. Conclusions: This is the first longitudinal study to assess microvascular complications in renal PTDM patients. A lower than expected prevalence as well as a different clinical course of the complications was observed. PTDM seems to be a unique type of diabetes and its consequences may be milder than expected in type 1 and type 2 diabetes. PMID- 30289494 TI - Race and Objective Social Isolation: Older African Americans, Black Caribbeans, and Non-Hispanic Whites. AB - Objectives: Social isolation is a major risk factor for poor physical and mental health among older adults. This study investigates the correlates of objective social isolation among older African Americans, black Caribbean immigrants, and non-Hispanic whites. Methods: The analysis is based on the older subsample (n = 1,439) of the National Survey of American Life. There are eight indicators of objective social isolation: no contact with neighbors, neighborhood groups, friends, family members, religious congregation members, not being married and no romantic involvement, living alone, and not being a parent. Results: Very few older Americans are socially isolated from family and friends. Non-Hispanic whites are more likely than both African Americans and black Caribbeans to live alone, to be childless, and have limited contact with religious congregation members. For both African Americans and black Caribbeans, being female is protective against social isolation, but for both populations, men are more likely to be married or have a romantic partner. For African Americans, residing in the South is also protective against social isolation. Discussion: This analysis provides greater clarity on racial and ethnic differences in social isolation among older adults, as well as within-group differences in objective social isolation among African Americans and black Caribbeans. PMID- 30289495 TI - THE INVESTIGATION OF MICRONUCLEI FREQUENCY DISTRIBUTION FOR EXPOSED AND UNEXPOSED PERSONNEL TO IONIZING RADIATION. AB - To establish at which extent the micronuclei (MN) frequency is influenced by occupational exposure to ionizing radiation, peripheral blood samples collected from 2151 subjects of both genders, smokers and non-smokers were analyzed. Among them, 378 (17.6%) were unexposed while the other 1773 (82.4%) were exposed to ionizing radiation for periods between 1 year and more than 30 years, at levels never overpassing legally regulated limits. The final results showed that for all investigated categories, MN frequency monotonously increases with the age by 1.75 +/- 0.17 times in the case of exposed subjects, but independent on gender and smoking habit. PMID- 30289496 TI - Ameliorating deleterious effects of heat stress on growing Muscovy ducklings using feed withdrawal and cold water. AB - We studied the effect of feed withdrawal and cold water on the growth performance and health status of 180 Muscovy ducklings (28 days old) during the summer season. The experiment used a 3 * 2 factorial design consisting of 3 and 2 feeding and water systems, respectively. The birds were divided into 6 experimental groups of 30 birds each (10/replicate). The 3 feeding systems were ad libitum, full-feeding (AD); afternoon, feed withdrawn from 8 am to 2 pm daily (AF); and diurnal, feed withdrawn from 2 pm to 8 am daily (DI). The 2 water systems were tap water (TW) or cold water (CW). The results indicated that the different feeding systems with cold water positively affected the growth performance, dressed carcass, liver, gizzard, meat tenderness, juiciness, susceptibility, body temperature, tonic immobility, and blood biochemistry (glucose, aspartate aminotransferase, alanine aminotransferase, total antioxidant capacity, and malondialdehyde) of Muscovy ducklings. However, no differences in percentages of plumage, leg problems, breast blister scores, and most blood parameters were found among all groups. In conclusion, AF feeding of ducklings in combination with CW during hot conditions was more suitable than other feeding methods. PMID- 30289497 TI - Impact of induced anxiety on neural responses to monetary incentives. AB - Previous research demonstrates that aversive stimuli can interrupt appetitive processing and that brain regions involved with the processing of potential rewards, such as the ventral striatum (VS), also respond to threatening information. Potential losses can likewise activate the VS and, thus, the full extent to which threat can impact neural responses during incentive processing remains unclear. Here, unpredictable threat of shock was used to induce anxiety while participants performed the monetary incentive delay (MID) task during functional magnetic resonance imaging (fMRI). During anticipation, anxiety impacted neural responses within the bilateral VS and distributed regions of the occipital cortex. Anxiety enhanced activity within the VS to both gain and loss trials. Furthermore, anxiety enhanced activity to both gain and loss trials within dorsal areas of BA19. However, anxiety only enhanced activity during gain, but not loss trials, within ventral areas of BA19. These results suggest that during anticipation, induced anxiety enhanced VS activity to incentives generally, which might reflect changes in the subjective salience of gains and losses. Collectively, these results suggest that the impact of induced anxiety on responses to monetary incentives depend on the neural region, type of incentive, and stage of processing. PMID- 30289498 TI - PATIENT DOSES IN COMMON DIAGNOSTIC X-RAY EXAMINATIONS. AB - A local survey was conducted, to evaluate the radiation dose to adult patients who underwent diagnostic X-ray examinations. Patient-related and technical data were recorded, in 1504 patients, for each of the 11 individual projections, of the 7 most common examinations performed in an X-ray room, with 1 digital radiography system. The patient entrance surface air kerma (ESAK) and the effective dose (ED) were calculated based on the X-ray tube output and the exposure parameters, as well as utilisation of suitable conversion coefficients, respectively. The 75th percentiles of the distribution of the ESAK and kerma area product (KAP) values were also established. The mean, median and 75th percentiles were compared with the national reference levels and the most common values reported at the European level through the DOSE DATAMED II project. The corresponding ED values were also compared with the average values reported for all European countries. The mean ESAK, KAP and ED values along with the uncertainty U values for chest PA, chest LAT, cranium AP, cranium LAT, cervical spine AP, cervical spine LAT, lumbar spine AP, lumbar spine LAT, pelvis AP, abdomen AP, kidneys and urinary bladder (KUB) AP were 0.12 (0.001) mGy, 0.66 (0.023) mGy, 1.01 (0.034) mGy, 0.69 (0.098) mGy, 0.72 (0.014) mGy, 0.63 (0.011) mGy, 4.12 (0.050) mGy, 5.74 (0.082) mGy, 2.57 (0.024) mGy, 1.94 (0.017) mGy, 2.47 (0.073) mGy, and 0.09 (0.001) Gy cm2, 0.38 (0.012) Gy cm2, 0.32 (0.009) Gy cm2, 0.27 (0.052) Gy cm2, 0.17 (0.004) Gy cm2, 0.21 (0.006) Gy cm2, 1.18 (0.018) Gy cm2, 1.86 (0.023) Gy cm2, 1.41 (0.012) Gy cm2, 1.27 (0.010) Gy cm2, 1.28 (0.038) Gy cm2, as well as 0.01 (0.0001) mSv, 0.05 (0.0016) mSv, 0.02 (0.0006) mSv, 0.01 (0.0012) mSv, 0.03 (0.0008) mSv, 0.03 (0.0006) mSv, 0.26 (0.0038) mSv, 0.17 (0.0022) mSv, 0.20 (0.0016) mSv, 0.23 (0.0018) mSv, 0.23 (0.0068) mSv, respectively. The 75th percentiles along with the uncertainty U values for chest PA, chest LAT, cranium AP, cranium LAT, cervical spine AP, cervical spine LAT, lumbar spine AP, lumbar spine LAT, pelvis AP, abdomen AP, kidneys and urinary bladder (KUB) AP were 0.14 (0.006) mGy, 0.88 (0.031) mGy, 1.22 (0.049) mGy, 0.94 (0.098) mGy, 0.93 (0.027) mGy, 0.78 (0.013) mGy, 5.16 (0.073) mGy, 7.24 (0.134) mGy, 2.96 (0.047) mGy, 2.59 (0.036) mGy, 3.07 (0.116) mGy, as well as 0.10 (0.0006) Gy cm2, 0.51 (0.017) Gy cm2, 0.37 (0.020) Gy cm2, 0.33 (0.040) Gy cm2, 0.23 (0.007) Gy cm2, 0.26 (0.011) Gy cm2, 1.50 (0.036) Gy cm2, 2.26 (0.035) Gy cm2, 1.61 (0.023) Gy cm2, 1.67 (0.017) Gy cm2, 1.56 (0.069) Gy cm2, in terms of ESAK and KAP values, respectively. The results were significantly lower compared with the national reference levels, the most common DRL values reported at the European level and other previously reported dose values. Patient dose surveys could contribute towards optimising radiation protection for patients, therefore, highlighting the necessity to increase the awareness and knowledge of the radiation dose in conjunction with the required image quality. PMID- 30289499 TI - A mono-component microbial protease improves performance, net energy, and digestibility of amino acids and starch, and upregulates jejunal expression of genes responsible for peptide transport in broilers fed corn/wheat-based diets supplemented with xylanase and phytase. AB - A total of 90 male Ross 308 broiler chicks were used in a digestibility and performance bioassay to explore the effect of reduction in dietary protein and digestible amino acids and inclusion of an exogenous mono-component protease on amino acid digestibility, net energy, jejunal gene expression, and bird performance. Four dietary treatments were created by the supplementation, or not, of 2 control diets with a mono-component exogenous protease. The control diets were corn/wheat/soybean meal-based and were formulated to be either nutritionally adequate or reduced in protein and amino acids (around 3%). The 2 control diets were supplemented with xylanase and phytase (2000 FYT). Treatments were therefore arranged as a 2 * 2 factorial design. The reduction in diet nutrient density had no significant effect on various experimental outcomes (including bird performance, amino acid digestibility, and net energy [NE]) that were measured with the exception of a reduction in the expression of aminopeptidase N and glucose transporter 2. However, the addition of exogenous protease resulted in an increase in weight gain and a reduction in feed conversion ratio (around 4%; P < 0.05) and an increase in the digestibility of several amino acids (P < 0.05) and starch (P = 0.06). Protease addition also resulted in an increase in both apparent metabolizable energy (AME) (+73 kcal/kg; P < 0.05) and NE (+107 kcal/kg; P < 0.05). The addition of exogenous protease to the diet also increased the jejunal expression of genes responsible for peptide transport (PepT2; P < 0.01) and starch digestion (sucrase isomaltase; P = 0.06). These results confirm the efficacy of exogenous protease in broiler diets that contain both xylanase and phytase and suggest substantial beneficial effects that extend beyond protein and amino acid nutrition. The effect of exogenous protease on energy partitioning, starch digestibility and the efficiency of nitrogen cycling is an area for further study. PMID- 30289500 TI - Self-Measured Arm Circumference in Women With Breast Cancer Is Reliable and Valid. AB - Background: Prospective surveillance by physical therapists enables early detection and treatment of breast cancer-related lymphedema (BCRL). Strategies to increase access to prospective surveillance could reduce the burden of BCRL on patients and the health system. One potential solution is self-managed surveillance that does not require in-person assessment by a specialized physical therapist. Objective: The objective was to develop and test the reliability and validity of a written and video-supported protocol for women with breast cancer to self-measure arm circumference. Design: This was a cross-sectional reliability and validity study. Methods: Participants with (n = 20) and without (n = 21) BCRL completed self-measurement of arm circumference on both arms at home (CIRself_home) and at the lab (CIRself_lab) (intrarater reliability). The CIRself_lab was subsequently compared to measures performed by a specialized physical therapist (CIRther) (interrater reliability). To test validity, arm volume calculated from the self-measurements (VOLself_lab) was compared to perometry measurements (VOLper). Participants completed a questionnaire to assess attitudes for performing self-managed surveillance for BCRL. Results: The intrarater reliability between CIRself_home and CIRself_lab and the interrater reliability between CIRself_lab and CIRther was high to excellent for both arms in both groups (ICC >= 0.86). VOLself_lab correlated strongly with VOLper (r >= 0.95), demonstrating excellent validity. Participants reported strong intention, self-efficacy, and positive attitude towards the performance of self-managed surveillance for BCRL, which was not perceived to increase worry about having or getting BCRL. Limitations: These findings need to be replicated in a clinical setting to confirm the reliability and acceptability of self-managed surveillance for BCRL among women newly diagnosed with breast cancer. Conclusions: Self measured arm circumference is reliable and valid among women with and without BCRL. Self-managed surveillance for BCRL may support self-efficacy without increasing anxiety. PMID- 30289501 TI - A SCREENING SURVEY EXERCISE FOR THYROID INTERNAL EXPOSURE FROM RADIOIODINE AFTER A NUCLEAR ACCIDENT. AB - In the aftermath of the 2011 Fukushima nuclear disaster, a screening survey for thyroid internal exposure from intake of radioiodine was performed on 1080 children using handheld NaI(Tl) survey meters. This article presents the design and results of a practical exercise conducted to develop the skills of personnel who would be potentially engaged in such a survey. Participants of this exercise were asked to measure manikin heads in which point sources were installed under normal (~0.05 MUSv h-1) and elevated (~0.5 MUSv h-1) background conditions. The results demonstrated that the measurements were less dependent on the background radiation level, and the deviation of net signals obtained by the participants were within 10-20% for dose rates above 0.2 MUSv h-1. This result suggests that dose rates can be reliably obtained above a provisional operational intervention level for the device, 0.5 MUSv h-1 under a real nuclear accident situation. PMID- 30289502 TI - The development of antioxidant system in the intestinal tract of broiler chickens. AB - The gastrointestinal tract is the site for the uptake of nutrients from the external environment. We hypothesized that the antioxidant system in the intestinal tract has a vital protective role from the oxidative damage induced by oxidants in foods. The aim of this study was to investigate the development of the antioxidant system in the intestine of chickens. The activity and gene expression of the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) and the content of the non-enzymatic substance glutathione (GSH) were measured in the duodenum, jejunum, and ileum of chickens at 1, 3, 7, 11, 14, 21, 35, and 42 d of age. The results showed that the small intestinal tract had relatively higher SOD activity and GSH concentration and lower CAT and GSH-Px activities, compared with those of other visceral organs. CAT and GSH-Px activities and GSH concentration showed a decreasing trend with age, whereas SOD activity was not significantly influenced by age. The gene expression of SOD1, SOD2, and GSH-Px7 showed a dramatic decrease from 3 d of age. The results indicated that SOD and GSH were highly expressed in the first week of age after hatching. To conclude, the results suggest that SOD and GSH play a vital protective role in the small intestine after hatching, which contributes to rapid development of the intestine. PMID- 30289504 TI - Phenotypic and Genotypic Plasticity of Acaricide Resistance in Populations of Tetranychus urticae (Acari: Tetranychidae) on Peppermint and Silage Corn in the Pacific Northwest. AB - Tetranychus urticae Koch is a generalist pest of economic crops and is notorious for its rapid development of acaricide resistance. This poses a significant threat to the sustainability of integrated pest management (IPM) in cropping systems plagued by T. urticae. It is critical to evaluate the resistance status of T. urticae populations on crops and identify any underlying resistance mechanisms. This study investigated the efficacy of five major acaricides on T. urticae populations on peppermint and silage corn in the Pacific Northwestern United States and identified the underlying resistance mechanisms. Significant variations in acaricide resistance status of T. urticae populations were identified to abamectin, bifenthrin, fenpyroximate, hexythiazox, and spirodiclofen. In most cases, T. urticae populations from silage corn exhibited greater levels of acaricide resistance relative to peppermint populations. We detected known target-site mutations: F1534S and F1538I (conferring resistance to bifenthrin), G126S (linked with resistance to bifenazate), and I1017 (conferring resistance to hexythiazox and etoxazole) in 10, 90, and 90% of the populations, respectively, from peppermint fields. These four mutations were identified in all the populations collected from silage corn fields. Significantly higher transcript levels of metabolic genes associated with resistance to abamectin, fenpyroximate, and spirodiclofen were observed in some T. urticae populations collected from both peppermint and silage corn fields. This study provides evidence of multiple resistance to diverse active ingredients in field populations of T. urticae and the reliability of known molecular markers for active acaricide resistance monitoring. The observed resistance pattern will help in designing a sustainable IPM program for T. urticae. PMID- 30289503 TI - NATURAL RADIOACTIVITY AND EVALUATION OF RADIATION HAZARDS IN SOILS FROM GRANITOIDE-GRANITE GEOLOGICAL FORMATION IN CUBA. AB - The natural radioactivity and the associated radiation hazards of soils from the Cumanayagua Granitoide-Granitic massif in the central south of Cuba have been studied. Mass activities of the natural radionuclides 238U, 232Th and 40K varied in the ranges 10.4-33, 4.6-21.7 and 381-1201 Bq kg-1, respectively. The radium equivalent activity (91.4 +/- 22.1 Bq kg-1), absorbed dose rate (45.6 +/- 11.1 nGy h-1), annual effective dose rate (56.1 +/- 13.7 MUSv y-1) and the external hazard index (0.25 +/- 0.06) have been calculated and compared with the internationally approved values. According to these results, the area can be regarded as an area with normal natural background radiation and may not pose radiological risks to the inhabitants owing to harmful effects of ionizing radiation from the natural radionuclides in soils. This study provides background radioactivity concentrations in Cumanayagua Granitoide area and generate a baseline data for radiological mapping of Cuba in the future. PMID- 30289505 TI - Selection of Reference Genes for Optimal Normalization of Quantitative Real-Time Polymerase Chain Reaction Results for Diaphorina citri Adults. AB - The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), can cause direct damage to citrus trees and is the main vector for the devastating disease, citrus greening disease or huanglongbing. Most molecular studies on this important insect pest use real-time reverse-transcription quantitative polymerase chain reaction (RT-qPCR) to quantify gene expression, including analyzing molecular basis for insecticide resistance in field populations. One critical factor to cause inaccuracy in RT-qPCR results is the lack of appropriate internal reference genes for optimal data normalization. In this study, the expression levels of 10 selected reference genes were evaluated in different tissue samples of psyllid adults and in the insects treated with different temperatures and insecticides. Data were analyzed using different computational algorithms, including Delta Ct, BestKeeper, NormFinder, geNorm, and RefFinder. According to our results, at least two reference genes should be used for the normalization of RT-qPCR data in this insect. The best choices of reference genes for different samples are as follows: ACT1 and Ferritin for different tissue samples, RPS20 and Ferritin for samples treated with different temperatures, TBP and EF1alpha for samples treated with imidacloprid, and Ferritin and TBP for samples treated with beta-cypermethrin. The reference genes identified in this study should be useful for future studies to analyze the expression patterns of target genes, especially for genes linked with temperature adaptability and insecticide resistance in this insect species in the future. PMID- 30289506 TI - Disruption of Phosphatidylserine Synthesis or Trafficking Reduces Infectivity of Ebola Virus. AB - The outer leaflet of the viral membrane of Ebola virus (EBOV) virions is enriched with phosphatidylserine (PtdSer), which is thought to play a central role in viral tropism, entry, and virus-associated immune evasion. We investigated the effects of inhibiting synthesis and/or export of PtdSer to the cell surface of infected cells on viral infectivity. Knockdown of both PtdSer synthase enzymes, PTDSS1 and PTDSS2, effectively decreased viral production. Decreased PtdSer expression resulted in an accumulation of virions at the plasma membrane and adjacent of intracellular organelles, suggesting that virion budding is impaired. The addition of inhibitors that block normal cellular trafficking of PtdSer to the plasma membrane resulted in a similar accumulation of virions and reduced viral replication. These findings demonstrate that plasma membrane-associated PtdSer is required for efficient EBOV budding, increasing EBOV infectivity, and could constitute a potential therapeutic target for the development of future countermeasures against EBOV. PMID- 30289507 TI - Healthy Post-Menarchal Adolescent Girls Demonstrate Multi-Level Reproductive Axis Immaturity. AB - Context: Menstrual irregularity after menarche has been attributed to immature estrogen positive feedback activity (E+FB) but data are conflicting. Objective: To determine the hypothalamic-pituitary-ovarian contributions to menstrual irregularity in adolescents. Methods: 23 healthy girls (aged 12.8-17.6 years, 0.4 3.5 years post-menarche, BMI [body mass index] percentile 41.0-99.3) underwent serial hormone measurements and pelvic ultrasounds during 2 consecutive menstrual cycles. Hormones and follicle growth were compared with 65 adult historic controls with ovulatory cycles (OV). Results: Girls had anovulatory cycles (ANOV; 30%), OV with a short luteal phase (short OV; 22%), or OV with normal luteal phase (normal OV; 48%) without differences in cycle length, chronologic or gynecologic age, or BMI. Adolescents showed a spectrum of E+FB (mid-cycle LH adjusted for pre-ovulatory estradiol [E2]); only normal OV girls were comparable to adults. All OV girls had lower E2, progesterone, and gonadotropins during the luteal phase and luteal-follicular transition compared with adults. Normal OV girls also had lower follicular phase LH and FSH levels, a longer follicular phase, a slower dominant follicle growth rate, and smaller estimated pre ovulatory follicle size than adults. Follicular phase E2 and INHB levels were lower in normal OV girls than in adults even after adjusting for differences in FSH and follicle size. Conclusions: Early post-menarchal girls with normal OV cycles demonstrate mature E+FB but continue to have lower gonadotropin levels, diminished ovarian responsiveness, and decreased corpus luteum sex steroid synthesis compared with adults, indicating that reproductive axis maturity requires coordinated development of all components of the hypothalamic-pituitary ovarian axis. PMID- 30289508 TI - The linc00152 Controls Cell Cycle Progression by Regulating CCND1 in 16HBE Cells Malignantly Transformed by Cigarette Smoke Extract. AB - Smoking is one of the major environmental risk factors for lung cancer. In recent years, the role of long-chain non-coding RNAs (lncRNA) in chemical carcinogenesis has attracted extensive research attention. In this study, we treated human bronchial epithelial cells with cigarette smoke extract (CSE) at a dose of 2 MUg/mL to establish a malignantly transformed cellular model (16HBE-M). Screening of lncRNAs highly expressed in transformed cells via differential analysis revealed a crucial role of linc00152 in CSE-induced malignant transformation. The linc00152 serum level in cigarette smoke extract-exposed individuals was increased in a dose-dependent manner and its high expression associated with metastasis and proliferation of lung cancer tissue. In malignantly transformed 16HBE-M cells, linc00152 was involved in regulation of cell adhesion, epithelial transition and other malignant phenotypes, which in turn, affected in vivo metastasis. Interference with linc00152 expression led to G1/S arrest and inhibition of proliferation of 16HBE-M and H1299 cells. Furthermore, linc00152 promoted cyclin D1 expression and G1/S transition by functioning as an endogenous competitive RNA targeting miR-193b. Our collective findings supported a critical regulatory role of linc00152 in cell cycle alterations and abnormal proliferation in CSE-induced malignant transformation of human bronchial epithelial cells. PMID- 30289509 TI - RADIATION DOSE TO PATIENTS IN CORONARY INTERVENTIONAL PROCEDURES: A SURVEY. AB - The objective of this study was to evaluate dose-area product (DAP) and peak skin dose (PSD) for coronary angiography (CA) and percutaneous coronary intervention (PCI). The DAP and PSD of 300 randomly selected patients who were referred to CA and/or PCI, over a period of 3 months were recorded and analyzed. The mean DAP of 32 Gy cm2 and mean PSD of 412 mGy for CA were lower than 118 Gy cm2 and 857 mGy, respectively, for PCI. The DAP range of 2-84 Gy cm2 for CA and 12-378 mGy for PCI were also established. The maximum value of PSD for PCI procedures reached above the 2 Gy threshold for erythema. However, these values are similar to those available in literature. Periodic surveys may be required to monitor and/or reduce radiation doses in coronary interventional procedures. PMID- 30289510 TI - Dual practice of public hospital physicians in Vietnam. AB - Although many public hospital physicians in Vietnam offer private service on the side, little is known about the magnitude and nature of the phenomenon so-called dual practice, let alone the dynamics between the public and private health sectors. This study investigates how and to what degree public hospital physicians engage in private practice. It also examines the commitment of dual practitioners to the public sector. The analysis is based on a hospital-based survey of 483 physicians at 10 public hospitals in four provinces of Vietnam. Nearly half of the participants in the study sample reported themselves as dual practitioners. Various types of private practice were mentioned. Private practice at health facilities owned by the private sector was the most prevalent, followed by private practice delivered at health facilities owned by the dual practitioners themselves. Private practice inside public hospitals was also noted. Dual practitioners were likely to be senior and hold management positions inside their public hospitals. Substantial income differences were found between dual practitioners and those physicians practicing exclusively in the public sector. The majority of dual practitioners, however, reported the willingness to give up private practice if certain conditions were met, such as a basic salary increase or non-pecuniary benefits. The main reasons dual practitioners gave for not leaving the public sector included a sense of public responsibility and opportunities to gain a broader professional network and more training. This study reiterates the significant challenges associated with dual practice, including its financial implications and possible effects on health care quality and access. The need for a high-quality workforce committed to the public sector is particularly critical, given the possibility of universal insurance coverage. Future research should address the need to improve data collection on physicians' dual practice and incorporate the topic in policy debates on health reform. PMID- 30289511 TI - The impact of ASEAN economic integration on health worker mobility: a scoping review of the literature. AB - The Association of Southeast Asian Nations (ASEAN) Economic Community (AEC) was inaugurated in December 2015 with the primary aim of achieving a strong and prosperous community through accelerating economic integration. The notion of a single market, underpinned by the free flow of trade in services and skilled labour, is integral to the spirit of the AEC. To facilitate the intra-regional mobility of health professionals, Mutual Recognition Arrangements (MRAs) were signed, for nursing in 2006 and for medicine and dentistry in 2009, and now sit within the AEC objectives. This study examines the observed and potential impact of the health-related MRAs on health worker mobility within the region, particularly with regard to qualified doctors and nurses. To explore the available evidence, the authors undertook a narrative literature and document review, consistent with the RAMESES guidelines for qualitative research in international development and policy making in the area of health. Peer-reviewed articles and the grey literature from the period beginning in 2005 were reviewed. We find that the implementation of health-related MRAs has been slow and complex due to a number of barriers and challenges, such as resistance to the inflow of health professionals by the local workforce, shortcomings in the implementing mechanisms and an individual preference among health professionals for seeking better opportunities outside the region. Despite increasing worker mobility generally within ASEAN through formal and informal mechanisms, the MRAs themselves do not appear yet to have facilitated the freer movement of health workers. To strengthen health worker mobility, the full implementation of the health-related MRAs is essential, requiring support from broader trade and immigration policies and a stronger political commitment. Policy makers in ASEAN Member States will need to manage competing national interests in order to harness support for effective implementation. PMID- 30289513 TI - Quality of low-fat chicken sausages with added chicken feet collagen. AB - The present study aimed to replace the fat in cooked chicken sausages with commercial hydrolyzed collagen powder and chicken feet gelatin and to assess the qualities underlying physicochemical and sensory parameters. Three sausages were prepared: SS (15% fat), SC (7.5% fat and 7.5% hydrolyzed collagen powder), and SG (7.5% fat and 7.5% chicken feet collagen). The reduction of fat increased the values of a*, b*, and Hue. With regard to emulsion stability, SG had the closest value (95.86%) to the standard (SS) value and was more stable than the SC sausage (87.33%). With regard to texture profile, the SC sausage had similar parameters to SS, and the SG sample had lower adhesiveness, gumminess, and chewiness. With regard to fatty acid profile, SG had the lowest atherogenic and thrombogenic indices. The use of 50% gelatin was viable because it increased emulsion stability and water retention, in addition to using byproduct to prepare healthier sausages, especially regarding fat reduction. PMID- 30289512 TI - Dietary deoxynivalenol and oral lipopolysaccharide challenge differently affect intestinal innate immune response and barrier function in broiler chickens. AB - Dietary deoxynivalenol (DON) impairs the intestinal immune system and digestive functions of broiler chickens. However, little is known whether increasing doses of DON similarly affect the intestinal functions in different segments of the small intestine in chickens and whether a second oral challenge may potentiate those effects. The present objective was to investigate the effect of increasing dietary DON concentrations on the relative expression of genes for tight junction proteins, mucins, toll-like receptors (TLR), and cytokines in duodenum and jejunum, jejunal mucosal permeability, as well as on alpha-1-acid glycoprotein and IgA in serum with or without an additional oral lipopolysaccharide (LPS) challenge. Eighty 1-d-old chickens were fed diets with increasing DON concentrations (0, 2.5, 5, and 10 mg DON/kg diet) for 5 wk. One day before sampling, half of the chickens received an oral challenge with 1-mg Escherichia coli O55:B5 LPS/kg BW. Ussing chambers were used to measure the jejunal permeability in birds receiving 10-mg DON/kg feed with or without LPS challenge and 0-mg DON/kg feed without LPS. Increasing DON concentrations of up to 5-mg DON/kg increased (P < 0.05) the duodenal expression of TLR2, IL6, and Claudin 1 (CLDN1) by up to 84%, 88%, and 48%, respectively, compared with the noncontaminated diet. Likewise, jejunal CLDN1 expression increased up to 23% in the chickens fed DON concentrations of up to 5-mg DON/kg diet (P < 0.05). Moreover, increasing DON concentrations linearly and quadratically decreased (P < 0.05) the jejunal expression of TLR2 and transforming growth factor-beta 1, respectively. The additional LPS challenge increased (P < 0.040) duodenal occludin expression by 10% as well as the jejunal tissue conductance in chickens of the 10 DON group (P = 0.050). In conclusion, dietary DON differently affected the duodenal and jejunal expression of genes for tight-junction proteins and proinflammatory signaling pathways. The additional LPS challenge did not potentiate the DON effect but it seemed to induce a certain up-regulation of the proinflammatory response in the duodenum and enhanced the mucosal permeability in the jejunum.

PMID- 30289525 TI - Feeding and lighting practices on small-scale extensive pastured poultry commercial farms in the united states. AB - As commercial free-range and pastured poultry production has gained increased popularity in the United States in recent years, there is a greater need to understand basic husbandry practices including feeding and lighting practices. Because husbandry practices vary greatly between individual commercial pastured poultry and free-range operations, gaining knowledge across a wide cross-section of producers is necessary to better understand current practices. Specifically, because feed is considered the most expensive part of poultry production with respect to operating cost, in collaboration with the American Pastured Poultry Producers Association, an on-line survey of commercial free-range and pastured poultry producers was conducted aimed primarily at evaluating feeding and lighting practices. Data were collected from 14 commercial pastured (n = 13) and free-range (n = 1) producers (6 broiler, 1 layer, and 7 broiler/layer facilities) across 9 U.S. states. Results showed that these operations most commonly use Cornish Cross for broiler production and ISA Brown and Australorp for egg production. Only 1 of the 14 farms calculates feed conversion ratio on a monthly basis. Estimates of Hen Month Egg Production (HMEP) resulted in HMEP percentages that were over 100% in 6 of the 7 farms that provided data. 5 of the 7 farms that have layers used supplemental lighting but do not use a lux meter. These lack of data reflect an important challenge with this segment of the poultry industry. Extension based outreach focused on enabling data collection and record-keeping and analysis are necessary. Despite its small sample size, this study's results provide some valuable insights with respect to feeding equipment and the current state of data collection for this segment of the poultry industry. PMID- 30289522 TI - Natural Disease Course of Ulcerative Colitis During the First Five Years of Follow-up in a European Population-based Inception Cohort-An Epi-IBD Study. AB - Background and Aims: Few population-based cohort studies have assessed the disease course of ulcerative colitis [UC] in the era of biological therapy and widespread use of immunomodulators. The aim of this study was to assess the 5 year outcome and disease course of patients with UC in the Epi-IBD cohort. Methods: In a prospective, population-based inception cohort of unselected patients with UC, patients were followed up from the time of their diagnosis, which included the collection of their clinical data, demographics, disease activity, medical therapy, and rates of surgery, cancers, and deaths. Associations between outcomes and multiple covariates were analysed by Cox regression analysis. Results: A total of 717 patients were included in the study. During follow-up, 43 [6%] patients underwent a colectomy and 163 [23%] patients were hospitalised. Of patients with limited colitis [distal to the left flexure], 90 [21%] progressed to extensive colitis. In addition, 92 [27%] patients with extensive colitis experienced a regression in disease extent, which was associated with a reduced risk of hospitalisation (hazard ratio [HR]: 0.5 95% CI: 0.3-0.8]. Overall, patients were treated similarly in both geographical regions; 80 [11%] patients needed biological therapy and 210 [29%] patients received immunomodulators. Treatment with immunomodulators was found to reduce the risk of hospitalisation [HR: 0.5 95% CI: 0.3-0.8]. Conclusions: Although patients in this population-based cohort were treated more aggressively with immunomodulators and biological therapy than in cohorts from the previous two decades, their disease outcomes, including colectomy rates, were no different. However, treatment with immunomodulators was found to reduce the risk of hospitalisation. PMID- 30289526 TI - West Nile in Europe: an increasing public health problem. PMID- 30289527 TI - Comparative effects of in ovo versus subcutaneous administration of the Marek's disease vaccine and pre-placement holding time on the intestinal villus to crypt ratios of Ross 708 broilers during early post-hatch development,. AB - Villus to crypt ratio (VCR) is used to quantify the microanatomical response of the intestine to various treatments. In early age chickens, comparative effects of the in ovo (i.o.) and s.c. methods of administration (moa) of the Marek's disease (MD) vaccine on 2 types of measurement of small intestinal VCR at 0 and 4 h post-hatch (poh) were investigated. The effects of moa and 4 and 18 h pre placement holding times (pht) on the VCR measurements at 168 h (7 d) poh were also investigated. In the jejunum of the small intestine, a standard method for VCR determination, based on 10 villus and crypt length measurements, was utilized for the calculation of villus to crypt length ratio (VCLR). In that same region, a single histomorphometric determination of the crypt and total mucosa areas using image analysis software was also used. Subtraction of the crypt area from the total mucosa area provided the villus area, allowing for calculation of the villus to crypt area ratio (VCAR). Across 0, 4, and 18 h of poh bird age, the VCLR of birds that received an s.c. vaccination was higher in comparison to that of those that received an i.o. vaccination. The highest and lowest VCAR values were observed in the s.c. treatment at 0 h poh and in the i.o. treatment at 4 h poh, respectively. Furthermore, at 168 h poh, VCLR values in the 18 h pht and s.c. vaccination group were higher than those in the 4 h pht and s.c. vaccination or 18 h and i.o. vaccination groups. In conclusion, the effects of pht and MD vaccine moa on VCR were dependent on the use of either the VCLR or VCAR method of measurement. However, regardless of method, s.c. injection overall led to a higher VCR through 4 h poh in Ross 708 broilers, and the effects of moa on VCLR at 168 h were influenced by pht. PMID- 30289529 TI - Specific mutations in presenilin 1 cause conformational changes in gamma secretase to modulate amyloid beta trimming. AB - gamma-Secretase generates amyloid beta peptides (Abeta) from amyloid precursor protein (APP) through multistep cleavages, such as endoproteolysis (epsilon cleavage) and trimming (gamma-cleavage). Familial Alzheimer's disease (FAD) mutations within the catalytic subunit protein of presenilin 1 (PS1) decrease gamma-cleavage, resulting in the generation of toxic, long Abetas. Reducing long Abeta levels has been proposed as an AD therapeutic strategy. Previously, we identified PS1 mutations that are active in the absence of nicastrin (NCT) using a yeast gamma-secretase assay. Here, we analyzed these PS1 mutations in the presence of NCT, and found that they were constitutively active in yeast. One triple, 13 double, and five single mutants enhanced epsilon-cleavage activity up to 2.7-fold. Furthermore, L241I, F411Y, S438P, and F441L mutations modulated trimming activities to produce more short-Abeta in yeast microsomes. When introduced in mouse embryonic fibroblasts, these mutations possessed similar or reduced epsilon-cleavage activity. However, two mutations, L241I and S438P, modulated trimming activities and changed the conformation of transmembrane domain 1, the substrate recognition site. These mutants had the opposite modulatory effects of FAD mutations and produced more short Abetas and fewer long Abetas. Our results provide insights into the relationship between PS1 conformational changes and gamma-secretase activities.

PMID- 30289530 TI - Validation of in vitro digestion using simulated small intestinal fluid with specific digestive activity to predict the metabolizable energy of feed ingredients for duck. AB - Two experiments were conducted to validate a method to prepare simulated small intestinal fluid (SSIF) for in vitro digestion in ducks. Experiment 1 compared the in vitro digestible energy (IVDE) of SSIF to endogenous small intestinal fluid (ESIF) on four feeds. The ESIF 1 or 2 obtained from two groups of jejunal cannulated ducks offered diet 1 (3,050 kcal/kg of ME and 19.95% of CP) or 2 (2,801 kcal/kg of ME and 14.90% of CP) was purified into raw enzyme power (REP) 1 or 2. SSIF 1 to 3 or 4 to 6 were prepared to mimic ESIF 1 or 2, respectively. The enzyme sources were REP 1 for SSIF 1 and 4, REP 2 for SSIF 2 and 5 or reagent enzymes for SSIF 3 and 6, respectively. The IVDE of each feed was determined with SSIF or ESIF. Experiment 2 was to validate whether REP 1 was more effective than only reagent enzymes to prepare SSIF. Ten feeds were determined with pepsin following SSIF 1 or 3 for IVDE 1 or 2, respectively. The accuracy of prediction model of true metabolizable energy (TME) from IVDE 1 or 2 was evaluated to validate the efficacy of SSIF. In experiment 1, higher activities of amylase, trypsin and chymotrypsin were observed in ESIF 1 than ESIF 2 (P < 0.05). The IVDE determined with SSIF 1 and 2 or 3 and 4 were more comparable to that of ESIF 1 or 2 than determinations with SSIF 3 or 6. In experiment 2, the mean IVDE 1 or 2 was 97.22% or 96.23% relative to TME, respectively, and both were highly correlated with TME (P < 0.01; R2 >= 0.98). However, the residual SD of TME prediction model with IVDE 1 was less than that generated with IVDE 2 (55 vs. 71 kcal/kg). In conclusion, the IVDE determined with in vitro digestion of pepsin following SSIF prepared with REP can predict accurately TME of feed for ducks. PMID- 30289532 TI - The arogenate dehydratase ADT2 is essential for seed development in Arabidopsis. AB - Phenylalanine (Phe) biosynthesis in plants is a key process, as Phe serves as precursor of proteins and phenylpropanoids. The prephenate pathway connects chorismate, final product of the shikimate pathway, with the biosynthesis of Phe and Tyr. Two alternative routes of Phe biosynthesis have been reported: one depending on arogenate, and the other on phenylpyruvate. Whereas the arogenate pathway is considered the main route, the role of the phenylpyruvate pathway remains unclear. Here, we report that the deficiency in ADT2, a bifunctional arogenate dehydratase (ADT)/ prephenate dehydratase (PDT) enzyme, causes embryo arrest and seed abortion. This result makes a clear distinction between the essential role of ADT2 and the five remaining ADTs from Arabidopsis, which display mostly overlapping functions. We have found that PHA2, a monofunctional PDT from yeast, restores the adt2 phenotype when it is targeted within the plastids, but not when is expressed in the cytosol. Similar results can be obtained by expressing ADT3, a monofunctional ADT. These results suggest that Phe can be synthesized from phenylpyruvate or arogenate when the bifunctional ADT2 is replaced by other ADT or PDT enzymes during seed formation, highlighting the importance of Phe biosynthesis for embryo development, and providing further insights into the plasticity of Phe biosynthesis. PMID- 30289533 TI - In vitro assessment of antifungal, antibacterial, and antiprotozoal drugs against clinical isolates of Conidiobolus lamprauges. AB - We have determined the in vitro activity of antifungal, antibacterial, and antiprotozoal drugs alone and in combination against seven Conidiobolus lamprauges clinical isolates. The assays were based on the M38-A2 protocol and the checkerboard microdilution method. The lowest inhibitory concentrations were observed for amphotericin B, miconazole (MCZ), terbinafine, and miltefosine (MTF) (MIC range 0.25-1; 2-8; 0.25-2; 2-16 MUg/ml, respectively). The main synergism observed was through the combination of azithromycin (AZI)+MTF and dapsone (DAP)+MTF (100%), AZI+DAP (85.7%), AZI+MCZ (57.1%) as well as MCZ plus CTX and DAP (42.9%). The in vitro activities suggest that the combination of MTF and AZI or DAP are promising candidate therapies for conidiobolomycosis. PMID- 30289531 TI - Role of Transmembrane Protein 16F in the Incorporation of Phosphatidylserine Into Budding Ebola Virus Virions. AB - Viral apoptotic mimicry, which is defined by exposure of phosphatidylserine (PtdSer) into the outer leaflet of budding enveloped viruses, increases viral tropism, infectivity and promotes immune evasion. Here, we report that the calcium (Ca2+)-dependent scramblase, transmembrane protein 16F (TMEM16F), is responsible for the incorporation of PtdSer into virion membranes during Ebola virus infection. Infection of Huh7 cells with Ebola virus resulted in a pronounced increase in plasma membrane-associated PtdSer, which was demonstrated to be dependent on TMEM16F function. Analysis of virions using imaging flow cytometry revealed that short hairpin RNA-mediated down-regulation of TMEM16F function directly reduced virion-associated PtdSer. Taken together, these studies demonstrate that TMEM16F is a central cellular factor in the exposure of PtdSer in the outer leaflet of viral membranes. PMID- 30289534 TI - Randomized controlled trials and real-world data: differences and similarities to untangle literature data. AB - Randomized controlled trials (RCTs) represent the gold-standard of medical evidence to assess the efficacy and safety of therapeutic interventions. However, the need to minimize bias and ensure the correct design to explore the study aims often affects the generalizability of results. As a consequence, the evidence derived from the most rigorous research strategy available is not always representative of the real-world settings for which this evidence is ultimately intended. Observational studies, in contrast, although affected by a number of potential confounders, can more effectively capture treatment characteristics and safety issues that had not been identified by previous RCTs, owing to the short duration of follow-up or highly selective inclusion criteria. The aim of this review is to provide a comparative summary of the main advantages and pitfalls of RCTs and real-world data, emphasizing the need for a constant integration of all available levels of evidence to provide the best care for patients. PMID- 30289535 TI - 20 years of experience with tumour necrosis factor inhibitors: what have we learned? AB - TNF inhibitors are biologic DMARDs approved for the treatment of active RA in mid 1990s. They still represent a valuable therapeutic option to control the activity, disability and radiographic progression of the disease. In the context of TNF inhibitors, there are currently several molecules and different administration routes that provide optimal treatment personalization, allowing us to respond to a patient's needs in the best possible way. The increasing use of TNF inhibitors has not only improved the management of RA, but it has also helped in our understanding of the pathogenetic mechanisms of the disease. This review focuses on the basis of this targeted therapy and on the knowledge gained from their use about therapeutic effects and adverse events. Effectiveness analysed from drug registries and safety issues are presented together with recent data on infections (in particular, Mycobacterium tuberculosis and hepatitis B), cancer (lymphoma, skin cancers) and cardiovascular risk. PMID- 30289536 TI - Tailored approach to rheumatoid arthritis treatment with TNF inhibitors: where do we stand? PMID- 30289537 TI - The influence of comorbidities on the efficacy of tumour necrosis factor inhibitors, and the effect of tumour necrosis factor inhibitors on comorbidities in rheumatoid arthritis: report from a National Consensus Conference. AB - Objective: To define the safety and efficacy of TNF inhibitors (TNFi) in RA patients with comorbidities. Methods: A National Consensus Conference adopted a five-step process to better address the place of TNFi in the treatment of RA. Here we report the work focused on the influence of comorbidities on TNFi efficacy and the effect of TNFi on comorbidities using a Population Intervention Comparison Outcome-based strategy from 8 April 2013 to 15 January 2016. Results: A total of 4453 hits were analysed, of which 10 were eligible for full review. Data show that the presence of comorbidities influences the treatment strategy and several clinical outcomes. The risk of solid cancer is similar in RA patients treated with TNFi or with conventional synthetic DMARDs, and the risk of recurrent breast cancer is not higher in RA patients treated with TNFi. The risk of developing serious infections is higher in RA patients receiving TNFi than conventional synthetic DMARDs. Patients with previous serious infections before starting TNFi are not at increased risk of subsequent serious infection. The hazard rate of hospitalization due to infections is not different among patients remaining on the same TNFi, or switching to a different TNFi or to an agent with another mechanism of action. Longer exposure to TNFi is associated with a reduction in the risk of cardiovascular events. Conclusion: Comorbidities affect RA treatment strategies and the efficacy of TNFi. TNFi treatment may decrease the risk of cardiovascular diseases and their use in patients with previous infection is not associated with a higher risk of recurrences. PMID- 30289538 TI - Immediate treatment with tumour necrosis factor inhibitors in synthetic disease modifying anti-rheumatic drugs-naive patients with rheumatoid arthritis: results of a modified Italian Expert Consensus. AB - Objective: To establish clinical consensus for the optimal placement of TNF inhibitor (TNFi) in DMARDs-naive RA patients. Methods: The steering group was composed of 15 Italian rheumatologists expert in the field of RA, who proposed and selected by consensus the clinically relevant questions on the role of TNFi treatment in DMARDs-naive RA patients. The question was rephrased according to the population, intervention, comparison and outcome statement. The available scientific evidence on this topic were collected by updating the systematic literature reviews used for the EULAR 2013 recommendations up to January 2016. The aspects evaluated in the studies concerned clinical efficacy, radiographic structural damage and safety. After the systematic literature review the expert panel formulated a consensus statement, and a modified Delphi panel evaluated the level of agreement between panellists (strength of recommendation). Results: From a total of 1080 records we have included 6 studies, 2 randomized clinical trials and 4 open-label extension trials. Evidence from publications generated three statements for the final consensus document. The systematic literature review and the consensus statements developed showed that, for patients with early RA and in the presence of a treat-to-target strategy, the immediate use of anti-TNFi compared with an early (within 12 weeks) step-up to anti-TNF therapy did not confer a significant advantage regarding clinical, functional and radiographic outcomes. Conclusion: The most appropriate placement of the TNFi therapy in the treatment algorithm of early RA still remains a challenging clinical question that needs to be further addressed. PMID- 30289539 TI - Switch or swap strategy in rheumatoid arthritis patients failing TNF inhibitors? Results of a modified Italian Expert Consensus. AB - Objective: To establish evidence-based and experts' opinion filtered statements on the optimal treatment choice between cycling (switch) and changing mode of action strategies (swap) in RA patients failing TNF inhibitors (TNFis). Methods: The relevant question (switch vs swap) was rephrased into a research question according to the population, intervention, comparison and outcome (PICO) strategy, considering all the available scientific evidence published from the 2013 EULAR set of recommendations up to mid-January 2016. Final statements derived from the retrieved scientific evidence and experts' consensus, with eventual rephrasing through a Delphi method during a national consensus of Italian rheumatologists. Results: From a total of 365 records, 12 studies were finally included. The final statements argued that, until head-to-head comparison data are available, switch and swap can be still considered suitable strategies in RA patients failing first TNFi, even though some data seem to lend more support to a different mode of action-targeted strategy. Conclusion: After failure of first TNFi course, switch and swap can be currently considered as alternative suitable approaches in RA patients.

PMID- 30289542 TI - ESTIMATION OF ORGAN DOSES AND EFFECTIVE DOSES BASED ON IN-PHANTOM DOSIMETRY FOR INFANT DIAGNOSTIC CARDIAC CATHETERISATIONS WITH NOVEL X-RAY IMAGING TECHNOLOGY. AB - The present study evaluated the organ and effective doses in infant diagnostic cardiac catheterisation performed using a modern x-ray imaging unit by in-phantom dosimetry. In addition, conversion factors from dose-area product (DAP) to effective dose were determined. The organ and effective doses in 1-year old during diagnostic cardiac catheterisations were measured using radiophotoluminescence glass dosemeters implanted into an infant anthropomorphic phantom. The mean effective doses, evaluated according to the International Commission on Radiologic Protection Publication 103, were 4.0 mSv (range: 1.5-8.7 mSv). The conversion factors from DAP to effective dose were 2 and 3.5 mSv (Gy cm2)-1 for posteroanterior and lateral fluoroscopy, respectively, and 1.8 and 3.3 mSv (Gy cm2)-1 for posteroanterior and lateral cineangiography, respectively. The dose data and conversion factors evaluated in the present study may be useful for estimating radiation exposure in infants during diagnostic cardiac catheterisation. PMID- 30289540 TI - Dose adjustments and discontinuation in TNF inhibitors treated patients: when and how. A systematic review of literature. AB - Objectives: To review the available evidence concerning the possibility of discontinuing and/or tapering the dosage of TNF inhibitors (TNFi) in RA patients experiencing clinical remission or low disease activity. Methods: A systematic review of the literature concerning the low dosage and discontinuation of TNFi in disease-controlled RA patients was performed by evaluation of reports published in indexed international journals (Medline via PubMed, EMBASE), in the time frame from 8 April 2013 to 15 January 2016. Results: We analysed the literature evaluating the efficacy and the safety of two different strategies using TNFi, decreasing dosage or discontinuation, in patients experiencing clinical remission or low disease activity. After the analysis of online databases, 25 references were considered potentially relevant and 16 references were selected. The majority of data concerned etanercept and adalimumab. Results suggested the induction of stable clinical remission or low disease activity by using TNFi followed by a dosage tapering and/or discontinuation of such drugs may be associated with the maintenance of a good clinical response in a subset of patients affected by early disease. Conclusion: RA patients treated early with TNFi and achieving their therapeutic clinical targets seem to maintain their clinical response after tapering or discontinuing TNFi. These data may allow physicians a more dynamic and tailored management of RA patients. PMID- 30289544 TI - Dietary amino acids under hypoxic conditions exacerbates muscle myopathies including wooden breast and white stripping. AB - The occurrence of wooden breast (WB) and white striping (WS) of broiler breast myopathies may be associated with least-cost feed formulations and the inclusion of greater amounts of synthetic amino acids. Two experiments were conducted to evaluate the effects of supplemental glutamine (Gln-/+, 0 and 1%) and arginine (Arg-/+, 0 and 0.25%) in a 2 * 2 factorial arrangement. Experiment 1 consisted of 8 replicates using 32 pens and focused on live performance to 44 d of age, carcass yield, and meat quality evaluations at 45 d of age. Live performance parameters including feed intake, BW gain, mortality, and feed conversion were evaluated. Post-harvest carcass yield, breast muscle quality (including WB and WS), proximate analysis, and mineral analysis of breast muscle and tibia bone were also evaluated. Experiment 2 comprised 4 replicates using 8 pens with weekly measurements of blood physiology and muscle myopathy development from 21 to 45 d of age. Broilers fed supplemental Gln and Arg (Gln+/Arg+) produced broilers with greater BW and improved FCR. The WB and WS severity increased with Gln+ diets, while only WB increased using Arg+ diets. Weekly observations revealed the greatest increase in WB myopathies occurred between 28 to 35 d, while WS significantly increased one week later (35 to 42 d). When comparing broilers of similar BW at 45 d, Gln+ diets resulted in greater WS scores and percentage breast muscle fat. Further analysis of WB and WS scores (independent of treatment affect) revealed that increased myopathy scores were associated with increased blood CO2, H2CO3, and reduced O2 with increased meat pH, moisture content, and Ca concentration. These results indicated that increased muscle Ca is associated with increased WB, while increased dietary glutamine and lack of oxygen may have resulted in a reverse flux of the citric acid cycle and reduced electron transport chain activity resulting in increased WS. PMID- 30289543 TI - Adrenoleukodystrophy: Guidance for Adrenal Surveillance in Males Identified by Newborn Screen. AB - Context: Adrenoleukodystrophy (ALD) is a peroxisomal disorder associated with neurologic decompensation and adrenal insufficiency. Newborn screening for ALD has recently been implemented in five states with plans to expand to all 50 states in the United States. Adrenal insufficiency ultimately develops in most males with ALD, but the earliest age of onset is not well established. Objective: These clinical recommendations are intended to address screening for adrenal insufficiency in boys identified to have ALD by newborn screen. Participants: Seven members of the Pediatric Endocrine Society Drug and Therapeutics/Rare Diseases Committee, with clinical experience treating children with ALD and adrenal insufficiency, and a pediatric endocrinologist and laboratory director were selected to be on the working committee. Consensus Process: The authors comprised the working group and performed systematic reviews of the published literature regarding adrenal insufficiency and ALD. The recommendations were reviewed and approved by the larger Pediatric Endocrine Society Drug and Therapeutics/Rare Diseases Committee and then by the Pediatric Endocrine Society Board of Directors. Conclusions: There is limited literature evidence regarding monitoring of evolving adrenal insufficiency in male infants and children with ALD. The recommendations suggest initiating assessment of adrenal function at diagnosis with ALD and regular monitoring to identify boys with adrenal insufficiency in a timely manner and prevent life-threatening adrenal crisis. These recommendations are intended to serve as an initial guide, with the understanding that additional experience will inform future guidelines. PMID- 30289545 TI - AN ASSESSMENT OF RADIATION EXPOSURE DOSES IN PATIENTS UNDERGOING PRIMARY PERCUTANEOUS CORONARY INTERVENTION BASED ON ANGIOGRAPHIC RECORDS. AB - The stochastic and non-stochastic (deterministic) effects of radiation dose in patients undergoing primary percutaneous coronary intervention (PPCI) have been investigated using data recorded by an angiographic monitoring system. A total of 132 patients with acute myocardial infarction referred to the angiography department of Vali-Asr hospital, Fasa, Iran, during the second half of 2016 were recruited. Quantities like dose-area product (DAP), total air kerma (Ka,r) and fluoroscopy time (FT) were calculated and converted into effective dose (ED) and peak skin dose (PSD). The values for Ka,r, DAP and FT equaled 80 399.20 +/- 63 312 mGy cm2, 1392.80 +/- 1155.373 mGy and 524.11 +/- 423.057 s, respectively, which were within the ranges reported in previous studies. After considering standard dose thresholds for Ka,r and PSD, it was revealed that only a small portion of patients had reached these thresholds and exceeded them (<3%). Moreover, ED < 20 mSv for the majority of patients was fairly consistent with results from a recent research in eight Belgian hospitals. It was shown that angiographic records are reliable for assessing radiation dose in patients. PMID- 30289547 TI - Mitochondrial Heat Shock Protein 60s Interact with What's This Factor 9 to Regulate RNA Splicing of ccmFC and rpl2. AB - Mitochondrial intron splicing is a plant-specific feature that was acquired during the coevolution of eukaryotic host cells and mitochondria. The elimination of these introns is facilitated by mitochondrial-targeted proteins encoded by its host, nucleus. What's this factor 9 (WTF9), a nucleus-encoded plant organelle RNA recognition (PORR) protein, is involved in the splicing of the mitochondrial group II introns rpl2 and ccmFC. Disruption of WTF9 causes developmental defects associated with the loss of cytochromes c and c1 in Arabidopsis. In the present study, using a co-immunoprecipitation assay, we found that HSP60s interacted with WTF9, which was further confirmed by a pull-down assay. HSP60s are molecular chaperones that assist with protein folding in both eukaryotic and prokaryotic cells. However, accumulating evidence suggests that HSP60s also participate in other biological functions such as RNA metabolism and RNA protection. In this study, we found that consistently with their interaction with WTF9, HSP60s interacted with 48 nucleotides of the ccmFC intron. In mutant studies, the double mutant hsp60-3a1hsp60-3b1 exhibited a small stature phenotype and reduced splicing efficiency for rpl2 and ccmFC. These observations were similar to those in wtf9 mutants and suggest that HSP60s are involved in the RNA splicing of rpl2 and ccmFC introns in mitochondria. Our findings suggest that HSP60s participate in mitochondrial RNA splicing through their RNA-binding ability. PMID- 30289546 TI - Efficiency and precision of microRNA biogenesis modes in plants. AB - Many evolutionarily conserved microRNAs (miRNAs) in plants regulate transcription factors with key functions in development. Hence, mutations in the core components of the miRNA biogenesis machinery cause strong growth defects. An essential aspect of miRNA biogenesis is the precise excision of the small RNA from its precursor. In plants, miRNA precursors are largely variable in size and shape and can be processed by different modes. Here, we optimized an approach to detect processing intermediates during miRNA biogenesis. We characterized a miRNA whose processing is triggered by a terminal branched loop. Plant miRNA processing can be initiated by internal bubbles, small terminal loops or branched loops followed by dsRNA segments of 15-17 bp. Interestingly, precision and efficiency vary with the processing modes. Despite the various potential structural determinants present in a single a miRNA precursor, DCL1 is mostly guided by a predominant structural region in each precursor in wild-type plants. However, our studies in fiery1, hyl1 and se mutants revealed the existence of cleavage signatures consistent with the recognition of alternative processing determinants. The results provide a general view of the mechanisms underlying the specificity of miRNA biogenesis in plants. PMID- 30289548 TI - A bZIP transcription factor, CaLMF, mediated light-regulated camptothecin biosynthesis in Camptotheca acuminata. AB - Camptothecin (CPT) has powerful biological activities and its analogs, irinothecan and topothecan, are effective anti-cancer drugs for clinical therapy. Camptothecin was first isolated from Camptotheca acuminata and its low accumulation in planta limits drug supply in the market. Previous works have confirmed that many environmental factors and plant hormones/elicitors could regulate CPT biosynthesis, but only light irradiance has a negative effect on CPT production in C. acuminata. Although light irradiance has been identified as a negative CPT biosynthesis regulator in C. acuminata for many years, the mechanisms of this regulation are still unknown. In order to search possible signal components involved in the process of light-regulated CPT biosynthesis, coexpression analysis was carried out according to the transcriptome database of Camptotheca above-ground green tissues. From coexpression analysis, a light responsive bZIP transcription factor, CaLMF (Light-Mediated CPT biosynthesis Factor), was identified and further investigations showed that overexpression of CaLMF down-regulated the expression of CPT biosynthesis genes and decreased the accumulation of CPT in leaves, while light-regulated expression of CPT biosynthesis genes and CPT production were abolished in CaLMF silencing leaves under shading treatment. Our results show that CaLMF is a significant light signaling component, which mediates light-regulated CPT biosynthesis in C. acuminata. PMID- 30289549 TI - CellMarker: a manually curated resource of cell markers in human and mouse. AB - One of the most fundamental questions in biology is what types of cells form different tissues and organs in a functionally coordinated fashion. Larger-scale single-cell sequencing and biology experiment studies are now rapidly opening up new ways to track this question by revealing substantial cell markers for distinguishing different cell types in tissues. Here, we developed the CellMarker database (http://biocc.hrbmu.edu.cn/CellMarker/ or http://bio bigdata.hrbmu.edu.cn/CellMarker/), aiming to provide a comprehensive and accurate resource of cell markers for various cell types in tissues of human and mouse. By manually curating over 100 000 published papers, 4124 entries including the cell marker information, tissue type, cell type, cancer information and source, were recorded. At last, 13 605 cell markers of 467 cell types in 158 human tissues/sub tissues and 9148 cell makers of 389 cell types in 81 mouse tissues/sub-tissues were collected and deposited in CellMarker. CellMarker provides a user-friendly interface for browsing, searching and downloading markers of diverse cell types of different tissues. Furthermore, a summarized marker prevalence in each cell type is graphically and intuitively presented through a vivid statistical graph. We believe that CellMarker is a comprehensive and valuable resource for cell researches in precisely identifying and characterizing cells, especially at the single-cell level. PMID- 30289550 TI - Quantitative Systems Toxicology Analysis of In Vitro Mechanistic Assays Reveals Importance of Bile Acid Accumulation and Mitochondrial Dysfunction in TAK-875 induced Liver Injury. AB - TAK-875 (fasiglifam), a GPR40 agonist in development for the treatment of type 2 diabetes (T2D), was voluntarily terminated in Phase III trials due to adverse liver effects. The potential mechanisms of TAK-875 toxicity were explored by combining in vitro experiments with quantitative systems toxicology (QST) using DILIsym(r), a mathematical representation of drug-induced liver injury. In vitro assays revealed that bile acid transporters were inhibited by both TAK-875 and its metabolite, TAK-875-Glu. Experimental data indicated that human bile salt export pump (BSEP) inhibition by TAK-875 was mixed while sodium taurocholate co transporting polypeptide (NTCP) inhibition by TAK-875 was competitive. Furthermore, experimental data demonstrated that both TAK-875 and TAK-875-Glu inhibit mitochondrial electron transport chain (ETC) enzymes. These mechanistic data were combined with a physiologically-based pharmacokinetic (PBPK) model constructed within DILIsym to estimate liver exposure of TAK-875 and TAK-875-Glu. In a simulated population (SimPopsTM) constructed to reflect T2D patients, 16/245 (6.5%) simulated individuals developed alanine aminotransferase (ALT) elevations, an incidence similar to that observed with 200 mg daily dosing in clinical trials. Determining the mode of bile acid transporter inhibition (Ki) was critical to accurate predictions. In addition, simulations conducted on a sensitive subset of individuals (SimCohortsTM) revealed that when either BSEP or ETC inhibition was inactive, ALT elevations were not predicted to occur, suggesting that the two mechanisms operate synergistically to produce the observed clinical response. These results demonstrate how utilizing QST methods to interpret in vitro experimental results can lead to an improved understanding of the clinically relevant mechanisms underlying drug-induced toxicity. PMID- 30289551 TI - Kids Nowadays Hear Better Than We Did: Declining Prevalence of Hearing Loss in US Youth, 1966-2010. AB - OBJECTIVES/HYPOTHESIS: To investigate factors associated with hearing impairment (HI) in adolescent youths during the period 1966-2010. STUDY DESIGN: Cross sectional analyses of US sociodemographic, health, and audiometric data spanning 5 decades. METHODS: Subjects were youths aged 12 to 17 years who participated in the National Health Examination Survey (NHES Cycle 3, 1966-1970; n = 6,768) and youths aged 12 to 19 years in the Third National Health and Nutrition Examination Survey (NHANES III, 1988-1994; n = 3,057) and NHANES (2005-2010; n = 4,374). HI prevalence was defined by pure-tone average (PTA) >= 20 dB HL for speech frequencies (0.5, 1, 2, and 4 kHz) and high frequencies (3, 4, and 6 kHz). Multivariable logistic models were used to estimate the odds ratio (OR) and 95% confidence interval (CI). RESULTS: Overall speech-frequency HI prevalence was 10.6% (95% CI: 9.7%-11.6%) in NHES, 3.9% (95% CI: 2.8%-5.5%) in NHANES III, and 4.5% (95% CI: 3.7%-5.4%) in NHANES 2005 to 2010. The corresponding high-frequency HI prevalences were 32.8% (95% CI: 30.8%-34.9%), 7.3% (95% CI: 5.9%-9.0%), and 7.9% (95% CI: 6.8%-9.2%). After adjusting for sociodemographic factors, overall high-frequency HI was increased twofold for males and cigarette smoking. Other significant risk factors in NHANES 2005 to 2010 included very low birth weight, history of ear infections/otitis media, ear tubes, fair/poor general health, and firearms use. CONCLUSIONS: HI declined considerably between 1966 to 1970 and 1988 to 1994, with no additional decline between 1988 to 1994 and 2005 to 2010. Otitis media history was a significant HI risk factor each period, whereas very low birth weight emerged as an important risk factor after survival chances improved. Reductions in smoking, job-related noise, and firearms use may partially explain the reduction in high-frequency HI. Loud music exposure may have increased, but does not account for HI differences. LEVEL OF EVIDENCE: NA. PMID- 30289552 TI - The effectiveness of peer support on self-efficacy and quality of life in adults with type 2 diabetes: A systematic review and meta-analysis. AB - BACKGROUND: Peer support has been suggested as a promising approach for diabetes management. No conclusive evidence exists on the effects of peer support on self efficacy and quality of life in adults with type 2 diabetes. OBJECTIVE: To assess the effectiveness of peer support on self-efficacy and the quality of life in adults with type 2 diabetes. DESIGN: A systematic review and meta-analysis of randomized controlled studies. DATA SOURCES: We searched PubMed, Embase, Cochrane Central Register of Controlled Trials and Allied Health Literature database guide for relevant literatures from inception to 30 September 2017. REVIEW METHODS: The review was conducted according to the guidelines of Cochrane Collaboration. The outcomes were self-efficacy and quality of life. The standardized mean difference and 95% confidence intervals were calculated for pooled results. RESULTS: A total of 15 studies met the inclusion criteria. The pooled results revealed that peer support did not significantly improve self-efficacy and quality of life in adults with type 2 diabetes, but significantly improved self-efficacy and quality of life in studies with intervention duration <=6 months. There was no evidence of publication bias. CONCLUSION: Peer support intervention did not lead to better effects on the improvement in self-efficacy and quality of life among adults with type 2 diabetes. However, peer support with intervention duration not more than 6 months had positive effects on self-efficacy and quality of life. More high quality studies with large sample size are needed to support or counter the results. PMID- 30289553 TI - Ethylene signaling regulates natural variation in the abundance of antifungal acetylated diferuloylsucroses and Fusarium graminearum resistance in maize seedling roots. AB - The production and regulation of defensive specialized metabolites play a central role in pathogen resistance in maize (Zea mays) and other plants. Therefore, identification of genes involved in plant specialized metabolism can contribute to improved disease resistance. We used comparative metabolomics to identify previously unknown antifungal metabolites in maize seedling roots, and investigated the genetic and physiological mechanisms underlying their natural variation using quantitative trait locus mapping and comparative transcriptomics approaches. Two maize metabolites, smilaside A (3,6-diferuloyl-3',6' diacetylsucrose) and smiglaside C (3,6-diferuloyl-2',3',6'-triacetylsucrose), were identified that could contribute to maize resistance against Fusarium graminearum and other fungal pathogens. Elevated expression of an ethylene signaling gene, ETHYLENE INSENSITIVE 2 (ZmEIN2), co-segregated with a decreased smilaside A : smiglaside C ratio. Pharmacological and genetic manipulation of ethylene availability and sensitivity in vivo indicated that, whereas ethylene was required for the production of both metabolites, the smilaside A : smiglaside C ratio was negatively regulated by ethylene sensitivity. This ratio, rather than the absolute abundance of these two metabolites, was important for maize seedling root defense against F. graminearum. Ethylene signaling regulates the relative abundance of the two F. graminearum-resistance-related metabolites and affects resistance against F. graminearum in maize seedling roots. PMID- 30289554 TI - In Vitro Hydrodynamic Evaluation of a Scaffold for Heart Valve Tissue Engineering. AB - Although prosthetic heart valves have saved many lives, the search for a living substitute continues with the aid of tissue engineering. Much progress has been made so far, but the translation of this technology to clinical reality remains a challenge, especially due to the structural complexity of heart valves and the harsh environment they are in. In a joint effort, researchers from Federal University of ABC and Institute Dante Pazzanese of Cardiology have conceived a new bioresorbable scaffold for heart valve tissue engineering (HVTE), whose hydrodynamic performance was first assessed and described in this work. The scaffold was studied at the mitral position of a left heart simulator from Escola Politecnica of the University of Sao Paulo, under 60 bpm and with no cell seeding. In this condition, two-dimensional particle image velocimetry was performed to investigate the flow during diastolic and systolic phases. The results indicate that the scaffold can withstand the required intraventricular pressures for a simulated normal physiologic condition in a bioreactor. Furthermore, the averaged (N = 150) velocity vector maps showed a smooth and well distributed flow during diastole and qualitatively demonstrated no-significant regurgitation at systole. PMID- 30289555 TI - Imaging microstructure of the barley rhizosphere: particle packing and root hair influences. AB - Soil adjacent to roots has distinct structural and physical properties from bulk soil, affecting water and solute acquisition by plants. Detailed knowledge on how root activity and traits such as root hairs affect the three-dimensional pore structure at a fine scale is scarce and often contradictory. Roots of hairless barley (Hordeum vulgare L. cv Optic) mutant (NRH) and its wildtype (WT) parent were grown in tubes of sieved (<250 MUm) sandy loam soil under two different water regimes. The tubes were scanned by synchrotron-based X-ray computed tomography to visualise pore structure at the soil-root interface. Pore volume fraction and pore size distribution were analysed vs distance within 1 mm of the root surface. Less dense packing of particles at the root surface was hypothesised to cause the observed increased pore volume fraction immediately next to the epidermis. The pore size distribution was narrower due to a decreased fraction of larger pores. There were no statistically significant differences in pore structure between genotypes or moisture conditions. A model is proposed that describes the variation in porosity near roots taking into account soil compaction and the surface effect at the root surface. PMID- 30289556 TI - Music intervention for pain and anxiety management of the primiparous women during labour: A systematic review and meta-analysis. AB - AIMS: To determine the effect of music on the management of pain and anxiety in primiparous women during labour. BACKGROUND: Music is cost-effective intervention in clinical practice to reduce pain, stress, and anxiety. However, a systematic review with meta-analysis for investigating its effects during labour is still lacking. DESIGN: A systematic review with meta-analysis. DATA SOURCES: MEDLINE, EMBASE, and CINAHL databases. REVIEW METHODS: Randomized controlled trials or quasi-experimental trials concerning the effects of music among primiparous women who were expected to give normal spontaneous delivery were searched and screened up to 31 July 2017. The recruited trials for this review were compliant with the standards of the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS: A total of 392 primiparous pregnant women (197 in the music intervention group and 195 in the routine care group) from five studies were included in this review. Music as an intervention seemed to lower the pain scores for primiparous women during labour, but the effect was not statistically significant. However, there was a significant benefit of music intervention compared with routine care for primiparous women during labour. In the sensitivity analysis, music intervention showed significant effect on the improvement of pain and anxiety for primiparous women during labour. CONCLUSION: Music intervention may be an effective intervention for the management of pain and anxiety for primiparous women during labour. PMID- 30289557 TI - Bibliometric analysis of six nursing journals from the Web of Science, 2012-2017. AB - AIM: The purpose of this study was to perform a bibliometric analysis of the six most important nursing journals according to the impact factor of the Science Citation Index through Web of Science(r) . The following journals were included: International Journal of Nursing Studies, Nurse Education Today, Journal of Nursing Scholarship, Nursing Outlook, Worldviews on Evidence-Based Nursing and the Journal of Advanced Nursing. BACKGROUND: In the nursing field, bibliometric analysis and maps have been used to analyse the production of some journals but not for the comparison of different journals. DESIGN/METHOD: Using descriptive bibliometrics, we studied scientific production of different journals and bibliometric maps were used to visualize the content of published articles. RESULTS: The six journals included showed that 3,937 articles were written by 1,1371 authors from 2,980 institutions and 84 countries from 2012 - 2017. Journal of Advanced Nursing had a greater number of publications and citations. The most prolific authors showed a tendency to publish first in Journal of Advanced Nursing and then in International Journal of Nursing Studies and Nurse Education Today. The frequency of citation was higher in International Journal of Nursing Studies followed by Journal of Advanced Nursing. The most collaborative authors and those with the most co-citations published more than half of their publications in Journal of Advanced Nursing. The topics most commonly researched by these authors were job satisfaction, collaborative practices, and nurse leaders. CONCLUSION: This bibliometric analysis contributes to the understanding of the current state of nursing research and its evolution. PMID- 30289558 TI - Eyes on the future - evidence for trade-offs between growth, storage and defense in Norway spruce. AB - Carbon (C) allocation plays a central role in tree responses to environmental changes. Yet, fundamental questions remain about how trees allocate C to different sinks, for example, growth vs storage and defense. In order to elucidate allocation priorities, we manipulated the whole-tree C balance by modifying atmospheric CO2 concentrations [CO2 ] to create two distinct gradients of declining C availability, and compared how C was allocated among fluxes (respiration and volatile monoterpenes) and biomass C pools (total biomass, nonstructural carbohydrates (NSC) and secondary metabolites (SM)) in well-watered Norway spruce (Picea abies) saplings. Continuous isotope labelling was used to trace the fate of newly-assimilated C. Reducing [CO2 ] to 120 ppm caused an aboveground C compensation point (i.e. net C balance was zero) and resulted in decreases in growth and respiration. By contrast, soluble sugars and SM remained relatively constant in aboveground young organs and were partially maintained with a constant allocation of newly-assimilated C, even at expense of root death from C exhaustion. We conclude that spruce trees have a conservative allocation strategy under source limitation: growth and respiration can be downregulated to maintain 'operational' concentrations of NSC while investing newly-assimilated C into future survival by producing SM. PMID- 30289559 TI - Enhancing validity through cognitive interviewing. A methodological example using the Epilepsy Monitoring Unit Comfort Questionnaire. AB - AIMS: To identify problematic items, assess completeness and user-friendliness, and undertake modifications to enhance face validity of the newly developed Epilepsy Monitoring Unit Comfort Questionnaire. DESIGN: Qualitative-descriptive cross-sectional study. METHODS: Five iterative rounds of cognitive interviewing were conducted with members of the target population between July - November 2017. Think-aloud technique, verbal probing, and observation were used, to assess how respondents understood and answered questions. Data analysis was based on the framework method; an eight-column framework matrix was created for this purpose. RESULTS: In 25 interviews, problems regarding completeness of the item pool, comprehension of items, retrieval of information, judgment while finding answers and reporting the appropriate responses could be detected. According to the results, 27 items remained unchanged, 11 items were reworded, and six items were added. Instructions section of the questionnaire was reworked, too. CONCLUSION: Although time-consuming, cognitive interviewing turned out to be a valuable approach for revealing problems in an instrument, which would, otherwise, remain undetected and threaten validity. PMID- 30289560 TI - OsTPS8 controls yield-related traits and confers salt stress tolerance in rice by enhancing suberin deposition. AB - Class I TREHALOSE-PHOSPHATE-SYNTHASE (TPS) genes affect salinity tolerance and plant development. However, the function of class IITPS genes and their underlying mechanisms of action are unknown. We report the identification and functional analysis of a rice class IITPS gene (OsTPS8). The ostps8 mutant was characterised by GC-MS analysis, an abscisic acid (ABA) sensitivity test and by generating transgenic lines. To identify the underlying mechanism, gene expression analyses, genetic complementation and examination of suberin deposition in the roots were conducted. The ostps8 mutant showed salt sensitivity, ABA sensitivity and altered agronomic traits compared to the wild type (WT), which could be rescued upon complementation. The dsRNAi line phenocopied the mutant, while the overexpression lines exhibited enhanced salt tolerance. The ostps8 mutant showed significantly reduced soluble sugars, Casparian bands and suberin deposition in the roots compared to the WT and overexpression lines. The mutant also showed downregulation of SAPKs (rice SnRK2s) and ABA-responsive genes. Furthermore, ostps8pUBI::SAPK9 rescued the salt sensitive phenotype of ostps8. Our results suggest that OsTPS8 may regulate suberin deposition in rice through ABA signalling. Additionally, SAPK9-mediated regulation of altered ABA-responsive genes helps to confer salinity tolerance. Overexpression of OsTPS8 was adequate to confer enhanced salinity tolerance without any yield penalty, suggesting its usefulness in rice genetic improvement. PMID- 30289561 TI - Quantitative measure of fitness in tri-trophic interactions and its influence on diet breadth of insect herbivores. AB - Herbivore-plant interactions should be studied using a tri-trophic approach, but we lack a quantitative measure of the combined effect of top-down and bottom-up forces on herbivore fitness. We propose the combination of the bi-trophic fitness slopes as a tri-trophic fitness measure. We use the relationship between fitness associated with top-down and bottom-up forces and the frequency of host plant use to calculate the top-down and bottom-up fitness slopes, which we then combine to obtain three possible directions of tri-trophic slopes. A positive tri-trophic slope indicates that herbivores have overall greater tri-trophic fitness on the more frequently used hosts. A null tri-trophic fitness slope indicates that herbivores have similar fitness on all host plants. A negative tri-trophic slope indicates that herbivores have generally lower fitness on the more frequently used hosts. We tested the explanation power of our method using data from the literature that tested herbivore host shifts and experimentally using a generalist herbivore with variable diet breadth across populations. We found that in host shifts, herbivores have higher tri-trophic fitness on the novel host, while in generalist populations, herbivores use most frequently the best host available. We present applications in other research areas and consider the limitations of our approach. Our approach is a first step towards a comprehensive model of multiple selective forces acting on the evolution of interactions. PMID- 30289562 TI - Maternal functional hemodynamics in uncomplicated twin pregnancies: A longitudinal study using impedance cardiography. AB - INTRODUCTION: Longitudinal studies of maternal hemodynamics in twin pregnancy are scarce and preload reserve in twin pregnancies has not been studied. Thus, we aimed to investigate serial changes in maternal systemic hemodynamics from the first to third trimester, and cardiovascular response to passive leg raising to evaluate preload reserve using impedance cardiography in a cohort of uncomplicated twin pregnancies. MATERIAL AND METHODS: This was a prospective longitudinal study of 50 twin pregnancies. Maternal hemodynamics was assessed at baseline and 120 seconds after passive leg raising using impedance cardiography, at five time points during gestation. Women were excluded from the analysis if there were pregnancy complications or fewer than three of five planned assessments were available. RESULTS: Data from 37 uncomplicated twin pregnancies were available for analysis. Mean arterial pressure slightly decreased until 17 weeks' gestation, then increased. Systemic vascular resistance was constant in the first half of pregnancy before rising steadily thereafter, whereas the cardiac output increased from the first trimester, peaked by the end of the second trimester and then decreased in the third trimester. The change in stroke volume and cardiac output following passive leg raising during pregnancy ranged from -2.2% to 1.6% and from -3.7% to 3.2%, respectively. Although passive leg raising caused no significant changes in systemic vascular resistance, cardiac output or heart rate, mean arterial pressure decreased in the first and second trimesters. CONCLUSIONS: In uncomplicated twin pregnancies, maternal cardiovascular adaptation is evident from the first trimester. Twin pregnancies show a reduced preload reserve in the second half of gestation. PMID- 30289563 TI - Determinants of non-adherence to antiretroviral therapy among Option B+ cases in Ndop and Fundong health districts, Northwest Region, Cameroon. PMID- 30289564 TI - Regulatory IFN-gamma-producing killer dendritic cells are enhanced in B6.MLR Faslpr /J lupus-prone mice. AB - A novel cell population denominated IFN-gamma-producing killer dendritic cells (IKDCs) have been recently described. These cells are lymphocytes lacking B- or T receptors, but they can be identified by the presence of B220+ CD38+ CD49b+ and low CD11c, among other cell surface markers. The main characteristics of IKDCs are the production of IFN-gamma and the ability to spontaneously kill tumor cells. We found that this population increases in B6.MLR-Faslpr /J mice. Interestingly, IKDCs increase with age and are more abundant in mice older than 6 months onward. To analyze whether these cells have any role in the induction of the lupus-like phenotype in the B6.MLR-Faslpr /J mice, IKDCs were purified and transferred into 6-month-old B6.MRL-Faslpr /J mice, then the presence of anti nuclear antibodies (ANAS) and anti-dsDNA antibodies were analyzed 2 and 4 months after the transfer. The results showed a reduction in the levels of these autoantibodies and increased survival of these mice, indicating that these cells may have a regulatory function. In vitro assays demonstrated that IKDCs reduced the proliferation of both autoreactive B and T cells, suggesting that these may be the mechanisms used by these cells to ameliorate the lupus-like phenotype in the B6.MRL-Faslpr /J mice. PMID- 30289565 TI - Interventionist versus expectant care for severe pre-eclampsia between 24 and 34 weeks' gestation. AB - BACKGROUND: Severe pre-eclampsia can cause significant mortality and morbidity for both mother and child, particularly when it occurs remote from term, between 24 and 34 weeks' gestation. The only known cure for this disease is delivery. Some obstetricians advocate early delivery to ensure that the development of serious maternal complications, such as eclampsia (fits) and kidney failure are prevented. Others prefer a more expectant approach, delaying delivery in an attempt to reduce the mortality and morbidity for the child that is associated with being born too early. OBJECTIVES: To evaluate the comparative benefits and risks of a policy of early delivery by induction of labour or by caesarean section, after sufficient time has elapsed to administer corticosteroids, and allow them to take effect; with a policy of delaying delivery (expectant care) for women with severe pre-eclampsia between 24 and 34 weeks' gestation. SEARCH METHODS: For this update, we searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) on 27 November 2017, and reference lists of retrieved studies. SELECTION CRITERIA: Randomised trials comparing the two intervention strategies for women with early onset, severe pre-eclampsia. Trials reported in an abstract were eligible for inclusion, as were cluster-trial designs. We excluded quasi randomised trials. DATA COLLECTION AND ANALYSIS: Three review authors independently assessed trials for inclusion and risk of bias, extracted data, and checked them for accuracy. We assessed the quality of the evidence for specified outcomes using the GRADE approach. MAIN RESULTS: We included six trials, with a total of 748 women in this review. All trials included women in whom there was no overriding indication for immediate delivery in the fetal or maternal interest. Half of the trials were at low risk of bias for methods of randomisation and allocation concealment; and four trials were at low risk for selective reporting. For most other domains, risk of bias was unclear. There were insufficient data for reliable conclusions about the comparative effects on most outcomes for the mother. Two studies reported on maternal deaths; neither study reported any deaths (two studies; 320 women; low-quality evidence). It was uncertain whether interventionist care reduced eclampsia (risk ratio (RR) 0.98, 95% confidence interval (CI) 0.06 to 15.58; two studies; 359 women) or pulmonary oedema (RR 0.45, 95% CI 0.07 to 3.00; two studies; 415 women), because the quality of the evidence for these outcomes was very low. Evidence from two studies suggested little or no clear difference between the interventionist and expectant care groups for HELLP (haemolysis, elevated liver enzymes, and low platelets) syndrome (RR 1.09, 95% CI 0.62 to 1.91; two studies; 359 women; low-quality evidence). No study reported on stroke. With the addition of data from two studies for this update, there was now evidence to suggest that interventionist care probably made little or no difference to the incidence of caesarean section (average RR 1.01, 95% CI 0.91 to 1.12; six studies; 745 women; Heterogeneity: Tau2 = 0.01; I2 = 63%).For the baby, there was insufficient evidence to draw reliable conclusions about the effects on perinatal deaths (RR 1.11, 95% CI 0.62 to 1.99; three studies; 343 women; low-quality evidence). Babies whose mothers had been allocated to the interventionist group had more intraventricular haemorrhage (RR 1.94, 95% CI 1.15 to 3.29; two studies; 537 women; moderate-quality evidence), more respiratory distress caused by hyaline membrane disease (RR 2.30, 95% CI 1.39 to 3.81; two studies; 133 women), required more ventilation (RR 1.50, 95% CI 1.11 to 2.02; two studies; 300 women), and were more likely to have a lower gestation at birth (mean difference (MD) -9.91 days, 95% CI -16.37 to -3.45 days; four studies; 425 women; Heterogeneity: Tau2 = 31.74; I2 = 76%). However, babies whose mothers had been allocated to the interventionist group were no more likely to be admitted to neonatal intensive care (average RR 1.19, 95% CI 0.89 to 1.60; three studies; 400 infants; Heterogeneity: Tau2 = 0.05; I2 = 84%). Babies born to mothers in the interventionist groups were more likely to have a longer stay in the neonatal intensive care unit (MD 7.38 days, 95% CI -0.45 to 15.20 days; three studies; 400 women; Heterogeneity: Tau2 = 40.93, I2 = 85%) and were less likely to be small-for-gestational age (RR 0.38, 95% CI 0.24 to 0.61; three studies; 400 women). There were no clear differences between the two strategies for any other outcomes. AUTHORS' CONCLUSIONS: This review suggested that an expectant approach to the management of women with severe early onset pre-eclampsia may be associated with decreased morbidity for the baby. However, this evidence was based on data from only six trials. Further large, high-quality trials are needed to confirm or refute these findings, and establish if this approach is safe for the mother. PMID- 30289566 TI - Drivers of species turnover vary with species commonness for native and alien plants with different residence times. AB - Communities comprising alien species with different residence times are natural experiments allowing the assessment of drivers of community assembly over time. Stochastic processes (such as dispersal and fluctuating environments) should be the dominant factors structuring communities of exotic species with short residence times. In contrast, communities should become more similar, or systematically diverge, if they contain exotics with increasing resident times, due to the increasing importance of deterministic processes (such as environmental filtering). We use zeta diversity (the number of species shared by multiple assemblages) to explore the relationship between the turnover of native species and two categories of alien species with different residence times (archaeophytes [introduced between 4000 BC and 1500 AD] and neophytes [introduced after 1500 AD]) in a network of nature reserves in central Europe. By considering multiple assemblages simultaneously, zeta diversity allows us to determine the contribution of rare and widespread species to turnover. Specifically, we explore the relative effects of assembly processes representing isolation by distance, environmental filtering, and environmental stochasticity (fluctuating environments) on zeta diversity using Multi-Site Generalized Dissimilarity Modelling (MS-GDM). Four clusters of results emerged. First, stochastic processes for structuring plant assemblages decreased in importance with increasing residence time. Environmental stochasticity only affected species composition for neophytes, offering possibilities to predict the spread debt of recent invasions. Second, native species turnover was well explained by environmental filtering and isolation by distance, although these factors did not explain the turnover of archaeophytes and neophytes. Third, native and alien species compositions were only correlated for rare species, whereas turnover in widespread alien species was surprisingly unrelated to the composition of widespread native species. Site specific approaches would therefore be more appropriate for the monitoring and management of rare alien species, whereas species-specific approaches would suit widespread species. Finally, the size difference of nature reserves influences not only native species richness, but also their richness-independent turnover. A network of reserves must therefore be designed and managed using a variety of approaches to enhance native diversity, while controlling alien species with different residence times and degrees of commonness. PMID- 30289567 TI - Manipulating host resistance structure reveals impact of pathogen dispersal and environmental heterogeneity on epidemics. AB - Understanding how variation in hosts, parasites, and the environment shapes patterns of disease is key to predicting ecological and evolutionary outcomes of epidemics. Yet in spatially structured populations, variation in host resistance may be spatially confounded with variation in parasite dispersal and environmental factors that affect disease processes. To tease apart these disease drivers, we paired surveys of natural epidemics with experiments manipulating spatial variation in host susceptibility to infection. We mapped epidemics of the wind-dispersed powdery mildew pathogen Podosphaera plantaginis in five populations of its plant host, Plantago lanceolata. At 15 replicate sites within each population, we deployed groups of healthy potted 'sentinel' plants from five allopatric host lines. By tracking which sentinels became infected in the field and measuring pathogen connectivity and microclimate at those sites, we could test how variation in these factors affected disease when spatial variation in host resistance and soil conditions was minimized. We found that the prevalence and severity of sentinel infection varied over small spatial scales in the field populations, largely due to heterogeneity in pathogen prevalence on wild plants and unmeasured environmental factors. Microclimate was critical for disease spread only at the onset of epidemics, where humidity increased infection risk. Sentinels were more likely to become infected than initially healthy wild plants at a given field site. However, in a follow-up laboratory inoculation study we detected no significant differences between wild and sentinel plant lines in their qualitative susceptibility to pathogen isolates from the field populations, suggesting that primarily non-genetic differences between sentinel and wild hosts drove their differential infection rates in the field. Our study leverages a multi-faceted experimental approach to disentangle important biotic and abiotic drivers of disease patterns within wild populations.

Temperature compensation IV. Temperature regulation of circadian behaviors V. Thermal adaptation of the clock: evolutionary considerations VI. Light and temperature information for the clock function - synergic or individual? VII. Concluding remarks and future prospects Acknowledgements References SUMMARY: Plant growth and development is widely affected by diverse temperature conditions. Although studies have been focused mainly on the effects of stressful temperature extremes in recent decades, nonstressful ambient temperatures also influence an array of plant growth and morphogenic aspects, a process termed thermomorphogenesis. Notably, accumulating evidence indicates that both stressful and nonstressful temperatures modulate the functional process of the circadian clock, a molecular timer of biological rhythms in higher eukaryotes and photosynthetic prokaryotes. The circadian clock can sustain robust and precise timing over a range of physiological temperatures. Genes and molecular mechanisms governing the temperature compensation process have been explored in different plant species. In addition, a ZEITLUPE/HSP90 mediated protein quality control mechanism helps plants maintain the thermal stability of the clock under heat stress. The thermal adaptation capability and plasticity of the clock are of particular interest in view of the growing concern about global climate changes. Considering these circumstances in the field, we believe that it is timely to provide a provoking discussion on the current knowledge of temperature regulation of the clock function. The review also will discuss stimulating ideas on this topic along with ecosystem management and future agricultural innovation. PMID- 30289569 TI - Prevalence and risk indicators of peri-implant diseases in Spain. AB - AIM: To evaluate the prevalence of peri-implant diseases in Spain, as well as the associated risk indicators. MATERIAL AND METHODS: This is a cross-sectional study using a network of sentinel dentists, who randomly selected 10 patients with implants (placed, at least, 5 years before), which were clinically and radiographically evaluated. Case definitions were established for peri-implant mucositis [bleeding on probing (BOP) and no bone level >=2 mm] and peri implantitis (BOP plus bone level >=2 mm). Potential predictor variables, at univariate and multivariate levels, were explored by means of binary logistic regression. RESULTS: A total of 49 sentinel dentists provided complete data from 474 implants in 275 patients. At implant level, prevalences for peri-implant mucositis and peri-implantitis were 27% (95% confidence interval [CI] 22-32) and 20% (95% CI: 15-24), respectively, with 17% of implants (14-21) with bone level >=2 mm without BOP. At patient level, prevalences were 27% (22-32), 24% (19-29) and 18% (13-22), respectively. In the multiple regression analysis, statistically significant associations for peri-implantitis (p < 0.10) were found for gender, peri-implant supportive therapy, implant location, diameter and surface, type of prosthesis and access to interproximal hygiene. CONCLUSIONS: In this representative subject sample across Spain, the prevalence of peri-implant diseases was high (51%).

AB - AIM: To synthesize the evidence relating to the ability of specialist care home support services to prevent the hospital admission of older care home residents, including hospital admission at the end-of-life. DESIGN: Systematic review and narrative synthesis. METHODS: Ten electronic databases will be searched from 2010 - 31 December 2018 using predetermined search terms. All studies of specialist healthcare services to meet care home residents' physical healthcare needs which provide outcome data on hospital admission or place of death compared with usual care will be included. Two reviewers will independently assess studies' eligibility and methodological quality using the Effective Public Health Practice Project Quality Assessment Tool. Data will be extracted by one reviewer and checked by a second according to predetermined categories. Data will be synthesized in evidence tables and narrative. Funder: National Institute for Health Research School for Social Care Research, November 2016. DISCUSSION: Care of older people in care home settings is a key aspect of nursing nationally and internationally. This review will increase understanding of the extent to which different models of specialist healthcare support for care homes are associated with key resident outcomes. IMPACT: Standard healthcare support for care home residents is often inadequate, resulting in avoidable hospital admissions and lack of resident choice as to place of death. Although a range of specialist healthcare services are emerging, little is known about their relative effectiveness. This paper marshalls evidence of relevance to commissioners investing in healthcare provision to care homes to meet NHS targets. PMID- 30289571 TI - Integrating spatial and phylogenetic information in the fourth-corner analysis to test trait-environment relationships. AB - The fourth-corner analysis aims to quantify and test for relationships between species traits and site-specific environmental variables, mediated by site specific species abundances. Since there is no common unit of observation, the significance of the relationships is tested using a double permutation procedure (site based and species based). This method implies that all species and sites are independent of each other. However, this fundamental hypothesis might be flawed because of phylogenetic relatedness between species and spatial autocorrelation in the environmental data. Here, using a simulation-based experiment, we demonstrate how the presence of spatial and phylogenetic autocorrelations can, in some circumstances, lead to inflated type I error rates, suggesting that significant associations can be misidentified. As an alternative, we propose a new randomization approach designed to avoid this issue, based on Moran's spectral randomization. In this approach, standard permutations are replaced by constrained randomizations so that the distribution of the statistic under the null hypothesis is built with additional constraints to preserve the phylogenetic and spatial structures of the observed data. The inclusion of this new randomization approach provides total control over type I error rates and should be used in real studies where spatial and phylogenetic autocorrelations often occur.

AB - There have been no established parameters to predict responsiveness to i.v. cyclophosphamide (IVCY) pulse therapy in combination with corticosteroids in patients with interstitial lung disease (ILD) related to systemic sclerosis (SSc). This retrospective study was conducted to determine predictive factors for efficacy of IVCY at the time of before and during the treatment. Thirty-two Japanese SSc patients, ever treated for ILD with IVCY in combination with prednisolone, were analyzed retrospectively. We performed detailed time-course analyses of parameters derived from blood samples and pulmonary function tests. With the exclusion of eight unclassified patients, 24 patients were classified into 14 good responders (GR) or 10 poor responders (PR) on the basis of changes in percent predicted diffusing capacity for carbon monoxide (DLco). Pretreatment percent predicted DLco was significantly reduced in PR compared with GR. In addition, serum parameters such as Krebs von den Lungen-6 (KL-6), surfactant protein D (SP-D) and C-reactive protein were significantly higher in PR than in GR. Furthermore, our time-course analyses revealed a transient increase in serum KL-6 levels with a peak at 3 months after the first infusion of cyclophosphamide, which showed no relation to therapeutic efficacy. Moreover, continuously high serum KL-6 levels (>2000 U/mL) and rapid decrease in SP-D levels (<200 ng/mL) during IVCY were remarkably characteristic of PR and GR, respectively. ILD severity/activity before treatment and variability of serum KL-6 and SP-D levels during treatment may be useful to predict therapeutic effects of IVCY on SSc-ILD.

AB - Serum amyloid A (SAA) is an acute phase protein, which activates immune cells and induces cytokines and chemokine. SAA levels in blood have been reported to be elevated in case of inflammation, infections, neoplasia and tissue injury. In this study, we examined SAA levels in the blood of patients with atopic dermatitis (AD) and cutaneous T-cell lymphoma (CTCL). SAA levels in sera of AD patients, those of CTCL patients and those of healthy controls were not significantly different. When AD or CTCL patients were classified by disease severity, there was still no difference in SAA levels. In AD patients, however, SAA levels positively correlated with the number of eosinophils in peripheral blood and serum soluble interleukin-2 receptor (sIL-2R) levels. There were significant correlations between SAA levels in blood and the number of white blood cells in peripheral blood and serum sIL-2R levels in CTCL patients. AD patients without topical steroid treatment and CTCL patients without narrowband ultraviolet B therapy showed increased levels of SAA, which suggested that SAA levels may easily fluctuate with treatment. These results imply a possible contribution of SAA in development of AD and CTCL. PMID- 30289575 TI - Exploration of resistance mechanisms for epidermal growth factor receptor tyrosine kinase inhibitors based on plasma analysis by digital polymerase chain reaction and next-generation sequencing. AB - Liquid biopsy offers a potential alternative to tissue biopsy for detection of genetic alterations in cancer, and it has been introduced into clinical practice to detect the tyrosine kinase inhibitor (TKI) resistance-conferring T790M mutation of epidermal growth factor receptor (EGFR) in patients with non-small cell lung cancer (NSCLC). We prospectively collected tumor and plasma samples from 25 NSCLC patients who harbored activating mutations of EGFR and experienced failure of treatment with afatinib. The samples were analyzed by digital PCR (dPCR) and next-generation sequencing (NGS). T790M was detected in plasma with a respective sensitivity and specificity of 83.3% and 70.0% by dPCR and 50.0% and 70.0% by NGS relative to analysis of corresponding tumor samples. Quantitation of T790M based on the ratio of the number of T790M alleles to that of activating mutation alleles (T/A ratio) improved the specificity of plasma analysis to 100% for both dPCR and NGS without a reduction in sensitivity. Although several afatinib resistance mechanisms other than T790M-including copy number gain of NRAS or MET-were identified in tumor samples, the corresponding genetic alterations were not detected in plasma. TP53 mutations were frequently identified in plasma and tumor samples, with most such mutations also having been detected before afatinib treatment. The presence of de novo TP53 mutations was associated with reduced progression-free survival. Quantitation of T790M in plasma is thus a clinically relevant approach to determine the T790M status of tumors. In addition, genetic alterations coexisting with EGFR mutations can affect the efficacy of EGFR-TKI treatment.

AB - The enantioselective cobalt(III)-catalyzed C-H alkylation was achieved through the design of a novel chiral acid. The cobalt(III)-catalyzed enantioselective C-H activation was characterized by high position-, regio- and enantio-control under exceedingly mild reaction conditions. Thereby, the robust cooperative cobalt(III) catalysis proved tolerant of valuable electrophilic functional groups, including hydroxyl, bromo, and iodo substituents. Mechanistic studies revealed a considerable additive effect on kinetics and on a negative non-linear-effect. PMID- 30289578 TI - Medication history assessment in research: A randomized controlled trial comparing tablet-based (eMedHAT) versus structured interview (MedHAT). AB - PURPOSE: Accurate capture of medication use is important for high quality research. For epidemiologic studies, medication histories are the most common measure of exposure when trying to identify associations between medications and outcomes. Concomitant medications can alter the efficacy or safety of study drugs in clinical trials. However, there are few studies evaluating the accuracy and efficiency of methods to collect these histories. The objective of this study is to compare the accuracy of medication histories collected by structured interview to histories captured using a tablet-based application. METHODS: This was a randomized controlled trial. Subjects were instructed to record all prescription medications, non-prescription medications, vitamins, and dietary supplements in a diary for 30 days. At the end of the diary collection, subjects were randomized to providing a medication history during a structured interview by a trained research assistant (MedHAT) or using a tablet-based application (eMedHAT). The accuracy of these histories was compared using an adjusted analysis. We also measured the duration of the history collection and data entry. RESULTS: A total of 111 subjects were in the MedHAT group and 109 subjects were in the eMedHAT group. Recall of medications for the 30-day period was similar for MedHAT and eMedHAT (76.9% versus 75.2%, respectively). The total time required for researchers and subjects for history collection and data entry was 16 minutes shorter for the tablet-based method. CONCLUSIONS: Tablet-based medication histories were as accurate as histories obtained by research assistants and required less time for the researcher. PMID- 30289579 TI - Ion-Reagent Interactions Contributing to Ionic Liquid Solvent Effects on a Condensation Reaction. AB - Molecular dynamics simulations of solutions of hexan-1-amine or 4 methoxybenzaldehyde in acetonitrile, an ionic liquid/acetonitrile mixture (chiIL =0.2), and a number of different (neat) ionic liquids were performed, to further understand the solvent effects on the condensation reaction of these species. This work indicates that, in the presence of an ionic liquid, the amine group of hexan-1-amine is exclusively solvated by the components of the ionic liquid, and not by acetonitrile, and that the anion interacts with the aldehyde group of 4 methoxybenzaldehyde. These interactions showed little dependence on the proportion of the ionic liquid present. When varying the cation of the ionic liquid there were changes in the cation-amine interaction, and 1-butyl-2,3 dimethylimidazolium bis(trifluoromethanesulfonyl)imide ([Bm2 im][N(CF3 SO2 )2 ]) was found to order more than expected about the amine. This ordering is likely the origin of the large rate constant values determined in [Bm2 im][N(CF3 SO2 )2 ] for this condensation reaction and explains an anomaly seen previously. When changing the anion, changes were seen in the interactions between both the cation and anion with hexan-1-amine, and the anion with 4-methoxybenzaldehyde. The differing magnitude of these interactions likely causes subtle changes in the activation parameters for this condensation reaction, and provides an explanation for the anomalous rate constant values previously determined when varying the anion. PMID- 30289580 TI - In-Plane Epitaxial Growth of Highly c-Oriented NH2 -MIL-125(Ti) Membranes with Superior H2 /CO2 Selectivity. AB - Preferred-orientation control has significant impact on the separation performance of MOF membranes. Under most conditions the preferred orientation of MOF membranes is dominated by the Van der Drift mechanism of evolutionary growth selection so that the obtained orientation may not be optimized for practical application. In this study, highly c-oriented NH2 -MIL-125 membranes were prepared on porous alpha-alumina substrates by combining oriented seeding and controlled in-plane epitaxial growth. Dynamic air-liquid interface-assisted self assembly of c-oriented NH2 -MIL-125(Ti) seed monolayers, the use of layered TiS2 as the metal precursor, and single-mode microwave heating were crucial in ensuring the preferred c-orientation while simultaneously suppressing undesired twin growth. Owing to reduced grain boundary defects, the prepared c-oriented membranes showed an ideal H2 /CO2 selectivity of 24.8, which was 6.1 times higher than that of their randomly oriented counterparts under similar operating conditions. PMID- 30289576 TI - Transduced caudal-type homeobox (CDX) 2/CDX1 can induce growth inhibition on CDX deficient gastric cancer by rapid intestinal differentiation. AB - Intestinal metaplasia induced by ectopic expression of caudal-type homeobox (CDX)2 and/or CDX1 (CDX) is frequently observed around gastric cancer (GC). Abnormal expression of CDX is also observed in GC and suggests that inappropriate gastrointestinal differentiation plays essential roles in gastric tumorigenesis, but their roles on tumorigenesis remain unelucidated. Publicly available databases show that GC patients with higher CDX expression have significantly better clinical outcomes. We introduced CDX2 and CDX1 genes separately into GC originated MKN7 and TMK1 cells deficient in CDX. Marked suppression of cell growth and dramatic morphological change into spindle-shaped flat form were observed along with induction of intestinal marker genes. G0-G1 growth arrest was accompanied by changed expression of cell cycle-related genes but not with apoptosis or senescence. Microarray analyses additionally showed decreased expression of gastric marker genes and increased expression of stemness associated genes. Hierarchical clustering of 111 GC tissues and 21 non-cancerous gastric tissues by selected 18 signature genes based on our transcriptome analyses clearly categorized the 132 tissues into non-cancer, "CDX signature" positive GC, and "CDX signature"-negative GC. Gene set enrichment analysis indicated that "CDX signature"-positive GC has lower malignant features. Immunohistochemistry of 89 GC specimens showed that 50.6% were CDX2-deficient, 66.3% were CDX1-deficient, and 44.9% were concomitant CDX2/CDX1-deficient, suggesting that potentially targetable GC cases by induced intestinal differentiation are quite common. In conclusion, exogenous expression of CDX2/CDX1 can lead to efficient growth inhibition of CDX-deficient GC cells. It is based on rapidly induced intestinal differentiation, which may be a future therapeutic strategy. PMID- 30289581 TI - Fluoride-Free Synthesis of Two-Dimensional Titanium Carbide (MXene) Using A Binary Aqueous System. AB - Two-dimensional (2D) titanium carbide (Ti3 C2 ) is emerging as an important member of the MXene family. However, fluoride-based synthetic procedures remain an impediment to the practical applications of this promising class of materials. Here we demonstrate an efficient fluoride-free etching method based on the anodic corrosion of titanium aluminium carbide (Ti3 AlC2 ) in a binary aqueous electrolyte. The dissolution of aluminium followed by in situ intercalation of ammonium hydroxide results in the extraction of carbide flakes (Ti3 C2 Tx , T=O, OH) with sizes up to 18.6 MUm and high yield (over 90 %) of mono- and bilayers. All-solid-state supercapacitor based on exfoliated sheets exhibits high areal and volumetric capacitances of 220 mF cm-2 and 439 F cm-3 , respectively, at a scan rate of 10 mV s-1 , superior to those of LiF/HCl-etched MXenes. Our strategy paves a safe way to the scalable synthesis and application of MXene materials. PMID- 30289583 TI - "To know or not to know...?" Push and pull in ever smokers lung screening uptake decision-making intentions. AB - BACKGROUND: In the United States, lung cancer screening aims to detect cancer early in nonsymptomatic current and former smokers. A lung screening pilot service in an area of high lung cancer incidence in the United Kingdom has been designed based on United States trial evidence. However, our understanding of acceptability and reasons for lung screening uptake or decline in a United Kingdom nontrial context are currently limited. OBJECTIVE: To explore with ever smokers the acceptability of targeted lung screening and uptake decision-making intentions. DESIGN: Qualitative study using semistructured focus groups and inductive thematic analysis to explore acceptability and uptake decision-making intentions with people of similar characteristics to lung screening eligible individuals. SETTING AND PARTICIPANTS: Thirty-three participants (22 ex-smokers; 11 smokers) men and women, smokers and ex-smokers, aged 50-80 were recruited purposively from community and health settings in Manchester, England. RESULTS: Lung screening was widely acceptable to participants. It was seen as offering reassurance about lung health or opportunity for early detection and treatment. Participant's desire to know about their lung health via screening was impacted by perceived benefits; emotions such as worry about a diagnosis and screening tests; practicalities such as accessibility; and smoking-related issues including perceptions of individual risk and smoking stigma. DISCUSSION: Decision making was multifaceted with indications that current smokers faced higher participation barriers than ex-smokers. Reducing participation barriers through careful service design and provision of decision support information will be important in lung screening programmes to support informed consent and equitable uptake. PMID- 30289582 TI - Efficacy of liquid-based genetic diagnosis of endometrial cancer. AB - Although liquid-based cytology (LBC) has increased the sensitivity of cytological diagnosis of endometrial cancer (EC) compared with conventional smear cytology, the sensitivity of LBC for the detection of EC is between 70% and 96% and remains unsatisfactory. In the present study, we compared the efficacy of LBC with liquid based genetic diagnosis (LBGDx) by amplicon sequencing of five genes including PTEN, PIK3CA, CTNNB1, KRAS, and TP53 in 48 LBC subjects who underwent endometrial screening. Consequently, LBC classified 15 samples as "positive or suspicious for malignancy" and the 15 were later confirmed as EC. However, LBC failed to identify five cases who were diagnosed as EC by additional transvaginal ultrasound and endometrial curettage, indicating that the sensitivity of cytology alone was 75% (15/20). LBGDx identified 11 pathogenic PTEN variants in 10 subjects, six PIK3CA variants in nine, three CTNNB1 variants in five, two KRAS variants in four, and three TP53 variants in three. Collectively, at least one pathogenic variant was identified in 19 subjects, which included 17 EC (15 endometrioid carcinoma and 2 endometrial carcinosarcomas), and one cervical adenocarcinoma. However, LBGDx did not identify any pathogenic mutations in three of the 20 EC, indicating that the sensitivity of LBGDx alone was 85% (17/20). Although five EC were negative for malignancy by LBC and three were negative for pathogenic mutations by LBGDx, the combination of LBC and LBGDx would successfully diagnose all 20 EC. These data suggested that LBGDx is a useful strategy to improve the sensitivity of screening of EC by LBC. PMID- 30289584 TI - Diffusion of advanced medical imaging technology, CT, and MRI scanners, in Iran: A qualitative study of determinants. AB - BACKGROUND: Low-income and middle-income countries have a lot of problems in providing the financial, human, and capital resources for advanced medical imaging technologies (AMITs). Proper distribution of such expensive equipment might increase access to these services and enhance the quality and efficiency of health care. The present study aimed to identify the factors affecting the diffusion of AMITs including CT and MRI in Iran. METHODS: This is a qualitative research conducted in 2017. A number of purposively chosen policy makers and managers from Ministry of Health, medical universities, hospitals, health insurance, and vendor companies were approached for face-to-face and semistructured interviews. Data analysis was done using thematic analysis method. RESULTS: Three categories of influential factors were identified, including contextual, stakeholder related, and situational factors. With regards to the stakeholders, the ministry and physicians played the most important role in the diffusion process of the AMITs. Health insurance organizations and vendor companies played a minor role in distribution of the equipment. Application of political pressure by the authorities on the Ministry of Health to issue licenses for the acquisition of AMITs was taken as the most important factor and the greatest challenge in the diffusion of devices. CONCLUSION: The results sought to assist health system authorities to manage diffusion of AMITs effectively and assign an equitable access to the expensive resources. The diffusion management together with utilization management could largely improve efficiency and cost containment. Medical technology diffusion management de facto needs policy instruments in both supply and demand sides. PMID- 30289585 TI - Development of an LC-MS/MS method for monitoring long term exposure to the parabens. AB - RATIONAL: Parabens, the alkyl esters of 4-hydroxybenzoic acid, are a family of compounds widely used as preservatives in cosmetic products, including for children, and some are permitted in foods. Parabens are known to be weak endocrine disruptor because they interfere with the function of endogenous hormones through binding to estrogen receptors. Therefore, the levels of parabens in biological samples indicate endocrine disruptive exposure. In particular, hair samples can provide information on accumulated exposure to parabens. METHODS: For monitoring of long term exposure to parabens, an improved analytical method for rapid and direct determination of parabens in hair sample was developed by ultra performance liquid chromatography-tandem mass spectrometry using on-line extraction. Five parabens (methyl-, ethyl-, propyl-, butyl-, and benzyl-paraben) were separated within 10 min after incubation with 1 N HCl. Parabens were separated using a Waters BEH C18 column (2.1 mm * 100 mm, 1.7 MUm) and a mobile phase consisting of 10 mM ammonium acetate in water and acetonitrile with a gradient program at a flow rate of 300 MUL/min. The analysis of the separated parabens was monitored with electrospray negative ionization tandem mass spectrometry (ESI/MS/MS). RESULTS: The linearities of the method was demonstrated by r2 >= 0.994. The limits of detection as defined by a signal to noise (S/N) ratio of 3 were 1 ~ 5 ng/g. The mean concentration of five parabens in human subjects hair was measured to be 55.6 +/- 24.3 ~ 136.9 +/- 48.5 ng/g. CONCLUSIONS: The levels of parabens in hair samples may play important role to understanding probable endocrine disruptive exposure, and the described method could be used to evaluate and monitor long term exposure of parabens as endocrine disruptor. PMID- 30289586 TI - Assessing performance of Taiwan hospitals using data envelopment analysis: In view of ownership. AB - With rapid economic development in Taiwan, people have greater awareness of health care and are paying more attention to it. From the perspective of hospital management, the scale of hospitals and efficiency improvement are of concern to hospital managers. However, the extent of efficiency will differ between public and private hospitals due to their different ownership and goals. The study aims to evaluate the efficiency of public and private hospitals and to investigate the influence of ownership on efficiency of hospitals. The differences between hospitals can be understood by analyzing the features of the organization of hospitals and their geographic environment. In this way, hospitals with relatively low efficiency will be able to make improvements based on concrete evidence. By means of the two-stage method, the efficiency scores of 182 hospitals in Taiwan are compared. In the first stage, the data envelopment analysis is applied to obtain the efficiency scores of hospitals. The results show that private hospitals are more efficient than public hospitals. In the second stage, Tobit regression is used to investigate the factors influencing efficiency obtained by the data envelopment analysis. The results indicate that there are differences between ownership in market competition and the average length of stay. PMID- 30289587 TI - Predictors of mitochondrial DNA copy number and damage in a mercury-exposed rural Peruvian population near artisanal and small-scale gold mining: An exploratory study. AB - Mitochondrial DNA (mtDNA) copy number (CN) and damage in circulating white blood cells have been proposed as effect biomarkers for pollutant exposures. Studies have shown that mercury accumulates in mitochondria and affects mitochondrial function and integrity; however, these data are derived largely from experiments in model systems, rather than human population studies that evaluate the potential utility of mitochondrial exposure biomarkers. We measured mtDNA CN and damage in white blood cells (WBCs) from 83 residents of nine communities in the Madre de Dios region of the Peruvian Amazon that vary in proximity to artisanal and small-scale gold mining. Prior research from this region reported high levels of mercury in fish and a significant association between food consumption and human total hair mercury level of residents. We observed that mtDNA CN and damage were both associated with consumption of fruit and vegetables, higher diversity of fruit consumed, residential location, and health characteristics, suggesting common environmental drivers. Surprisingly, we observed negative associations of mtDNA damage with both obesity and age. We did not observe any association between total hair mercury or, in contrast to previous results, age, with either mtDNA damage or CN. The results of this exploratory study highlight the importance of combining epidemiological and laboratory research in studying the effects of stressors on mitochondria, suggesting that future work should incorporate nutritional and social characteristics, and caution should be taken when applying conclusions from epidemiological studies conducted in the developed world to other regions, as results may not be easily translated. 2018 Wiley Periodicals, Inc. PMID- 30289588 TI - White matter microstructure in fetal alcohol spectrum disorders: A systematic review of diffusion tensor imaging studies. AB - Diffusion tensor imaging (DTI) has revolutionized our understanding of the neural underpinnings of alcohol teratogenesis. This technique can detect alterations in white matter in neurodevelopmental disorders, such as fetal alcohol spectrum disorder (FASD). Using Prisma guidelines, we identified 23 DTI studies conducted on individuals with prenatal alcohol exposure (PAE). These studies confirm the widespread nature of brain damage in PAE by reporting diffusivity alterations in commissural, association, and projection fibers; and in relation to increasing cognitive impairment. Reduced integrity in terms of lower fractional anisotropy (FA) and higher mean diffusivity (MD) and radial diffusivity (RD) is reported more consistently in the corpus callosum, cerebellar peduncles, cingulum, and longitudinal fasciculi connecting frontal and temporoparietal regions. Although these interesting results provide insight into FASD neuropathology, it is important to investigate the clinical diversity of this disorder for better treatment options and prediction of progression. The aim of this review is to provide a summary of different patterns of neural structure between PAE and typically developed individuals. We further discuss the association of alterations in diffusivity with demographic features and symptomatology of PAE. With the accumulated knowledge of the neural correlates of FASD presenting symptoms, a comprehensive understanding of the heterogeneity in FASD will potentially improve the disease management and will highlight the diagnostic challenges and potential areas of future research avenues, where neural markers may be beneficial. PMID- 30289589 TI - Heterolysis of Dihydrogen by Nucleophilic Calcium Alkyls. AB - beta-Diketiminato (BDI) calcium alkyl derivatives undergo hydrogenolysis with H2 to regenerate [(BDI)CaH]2 , allowing the catalytic hydrogenation of a wide range of 1-alkenes and norbornene under very mild conditions (2 bar H2 , 298 K). The reactions are deduced to take place with the retention of the dimeric structures of the calcium hydrido-alkyl and alkyl intermediates via a well-defined sequence of Ca-H/C=C insertion and Ca-C hydrogenation events. This latter deduction is strongly supported by DFT calculations (B3PW91) performed on the 1-hexene/H2 system, which also indicates that the hydrogenation transition states display features which discriminate them from a classical sigma-bond metathesis mechanism. In particular, NBO analysis identifies a strong second order interaction between the filled alpha-methylene sp3 orbital of the n-hexyl chain and the sigma* orbital of the H2 molecule, signifying that the H-H bond is broken by what is effectively the nucleophilic displacement of hydride by the organic substituent. PMID- 30289590 TI - User involvement in digital health: Working together to design smart home health technology. AB - BACKGROUND: Public involvement adds value to numerous aspects of health research, yet few studies have attempted to evaluate its impact on research. Evidence of such impact is needed to develop recommendations for best practice and ensure adequate resourcing. AIM: To evaluate public involvement within a large interdisciplinary Science, Technology, Engineering and Mathematics (STEM) research project that focused on digital health. METHODS: The evaluation was conducted with members of the project's Public Advisory Groups (PAG) and with researchers who had participated in involvement activities. Two questionnaires were designed based on a public involvement value systems and clusters framework. RESULTS: Responses from members of the PAG (n = 10) were mostly positive towards normative values, which include moral, ethical and political aspects of involvement in research, and towards values concerning the conduct of public involvement and best practices. Researchers' responses (n = 16) indicated they felt that involvement was generally effective and increased the quality, relevance and generalizability of their work. However, their responses about the validity of involvement in research were varied. They also highlighted several challenges including how well public involvement impacted on research, how decisions made in the research might differ from the views generated from public involvement, and barriers to researchers' participation. DISCUSSION AND CONCLUSION: Our evaluation suggests that members of the public and the researchers value involvement. However, there is a need to consider how to embed public involvement to an even greater extent in STEM contexts and a need to address any barriers for researchers' own involvement. PMID- 30289591 TI - Effect of preparation design on marginal and internal adaptation of translucent zirconia laminate veneers. AB - This study investigated the effect of preparation design on the marginal and internal adaptation of laminate veneers (LVs) fabricated from translucent zirconia. Thirty-three resin teeth were prepared for LVs of three designs: window preparation (WP); incisal shoulder preparation (ISP); and incisal palatal chamfer preparation (IPP). Marginal adaptation was evaluated by measuring the vertical discrepancy between the LV margin and the finish line at 60 points. The internal adaptation was assessed by measuring the internal space width as the distance between the LV and the tooth at cervical, central, and incisal sites after sectioning. At the incisal, mesial, and distal sites, mean marginal discrepancies were significantly lower in the WP group than in the other two groups; the IPP group had the highest marginal discrepancies. At incisal sites, the median internal space was significantly higher in the IPP group than in the WP and ISP groups and higher in the ISP group than in the WP group. At the incisal site, marginal and internal adaptations were better for the non-overlap translucent zirconia LV design (WP) than for the overlap designs (ISP and IPP). The characteristics of the translucent zirconia LVs used in the present study indicate acceptable clinical performance.

AB - BACKGROUND: Coproduction is an approach increasingly recognized across public services internationally. However, awareness of the term and the barriers and facilitators to its implementation in the NHS are not widely understood. This study examines clinician and public perceptions of coproduction within the context of the Prudent Healthcare initiative. OBJECTIVES: To provide insights into how coproduction is viewed by clinicians and the public and identify perceived barriers and facilitators to its implementation. DESIGN: Using qualitative research methods, interviews were conducted with the public (n = 40) and clinicians (n = 40). Five focus groups were also conducted with the public (n = 45) and six focus groups with clinicians (n = 26). The COM-B model was used to analyse the data; key domains include Capability, Opportunity and Motivation. SETTING: This is an all-Wales study, involving six Health Boards, an NHS trust and community and patient groups. RESULTS: Key barriers relating to Capability include lack of awareness of the term coproduction and inadequate communication between clinicians and citizens. Opportunity-centred barriers include service and time constraints. Conversely, facilitators included utilizing partnerships with community organizations. Motivation-related barriers included preconceptions about patients' limitations to coproduce. CONCLUSIONS: There were broadly positive perceptions among participants regarding coproduction, despite initial unfamiliarity with the term. Despite study limitations including underrepresentation of employed public participants and junior doctors, our analysis may assist researchers and policymakers who are designing, implementing and evaluating interventions to promote coproduction.

AB - The architecture and composition of bone tissue engineering scaffolds play important roles in modulating the growth of bone tissue. Composite fibers composed of poly(lactic-co-glycolic acid) (PLGA) skeleton coated with hydroxyapatite (HA) or hydroxyapatite/collagen (HA/Col) were successfully produced via electrospinning, biomimetic process, and adsorption. The PLGA skeleton fabricated by electrospinning process with a nanofibrous structure (diameter ranging from 200 to 400 nm) showed a morphologic similarity to the extracellular matrix (ECM). SEM, EDX, and XRD analysis confirmed the presence of HA and Col on the composite fibers. Mesenchymal stem cells were used to evaluate the cellular behaviors including cell attachment and spreading, proliferation, and osteogenic differentiation on these fibers (PLGA, PLGA/HA, and PLGA/HA/Col). The results demonstrated that the HA and HA/Col coating improved the interaction between mesenchymal stem cells and the composite fibers reflected by accelerated cell spreading, increased alkaline phosphatase (ALP) activity and enhanced expression of osteogenic-related genes. The HA/Col coating was more effective in improving this interaction compared with HA coating. The PLGA/HA/Col composite fibers may be promising as a candidate scaffold for bone tissue engineering.

PMID- 30289594 TI - Haploinsufficiency of NCOR1 associated with autism spectrum disorder, scoliosis, and abnormal palatogenesis. AB - NCOR1 (nuclear receptor corepressor 1) is a transcriptional coregulatory protein that regulates the balance between histone acetylation and histone deacetylation. NCOR1 is listed as one of the 3,230 dose-sensitive genes which very rarely show truncating mutations in the pediatric population without severe diseases, even in a heterozygous state. In a large cohort study of intellectual disability/autism spectrum disorder, splicing mutations were identified in two individuals, however, the truncating effects of these splicing mutations have not been examined at the transcription level. We describe a 3-year-old girl who had behavior consistent with autism spectrum disorder, a bifid uvula, and early-onset scoliosis. Trio exome analysis showed a de novo heterozygous mutation at the splice donor site in exon 19 of NCOR1, c.2182 + 1G > T (NM_00190440.1). Reverse transcription polymerase chain reaction assay confirmed that the splicing mutation results in skipping of exon 19, a shift in the reading frame and then to nonsense-mediated mRNA decay. This patient represents the first patient who has had unequivocal documentation of haploinsufficient for the NCOR1 gene. Based on our observations, we conclude that NCOR1 is indeed a human disease-causing gene. We further suggest that bifid uvula, a micro form of cleft palate, may well be causally related to de novo NCOR1 haploinsufficiency, in that a previously reported deletion mapping study of atypical Smith-Magenis syndrome patients with large deletions and cleft palate identified that NCOR1, the only loss-of-function intolerant gene within the region, is located in the smallest region of overlap.

PMID- 30289596 TI - Preliminary observations of mitochondrial dysfunction in Prader-Willi syndrome. AB - Prader-Willi syndrome (PWS) is a complex multisystem disorder because of errors in genomic imprinting with severe hypotonia, decreased muscle mass, poor suckling, feeding problems and failure to thrive during infancy, growth and other hormone deficiency, childhood-onset hyperphagia, and subsequent obesity. Decreased energy expenditure in PWS is thought to contribute to reduced muscle mass and physical activity but may also relate to cellular metabolism and disturbances in mitochondrial function. We established fibroblast cell lines from six children and adults with PWS and six healthy controls for mitochondrial assays. We used Agilent Seahorse XF extracellular flux technology to determine real-time measurements of several metabolic parameters including cellular substrate utilization, Adenosine Triphosphate (ATP)-linked respiration, and mitochondrial capacity in living cells. Decreased mitochondrial function was observed in the PWS patients compared to the healthy controls with significant differences in basal respiration, maximal respiratory capacity, and ATP-linked respiration. These results suggest disturbed mitochondrial bioenergetics in PWS although the low number of studied subjects will require a larger subject population before a general consensus can be reached to identify if mitochondrial dysfunction is a contributing factor in PWS. PMID- 30289597 TI - Effect of hydroxyapatite nanoparticles and wedelolactone on osteoblastogenesis from bone marrow mesenchymal stem cells. AB - Regenerative medicine has a high demand for the development of scaffold materials combined with other osteogenic inducers to generate bioactive composite materials for bone replacement therapies. Previously, we reported that wedelolactone promoted osteoblastogenesis of bone marrow mesenchymal stem cells (BMSCs). In this study, the effect of hydroxyapatites (HAps), bone composite materials we prepared, and the combined effect of wedelolactone and HAps on osteoblastogenesis differentiation was first evaluated. Three kinds of HAps constructed by a rod like shape with particle size of 25 nm (HAp-1), 37 nm (HAp-2), and 33 nm (HAp-3) did not affect BMSC survival, but induced activity of alkaline phosphatase(ALP), a marker enzyme for osteoblastogenesis. HAp-1 treatment resulted in a more significant increase in the number of ALP staining-positive BMSC, and maintained an extended time for the increased number of ALP staining-positive BMSC. Moreover, HAp-1 combined with wedelolactone induced a higher ALP activity for a longer time than HAp-2 and HAp-3, and also increased the bone mineralization level. Osteoblastogenesis-related marker genes expression including osteorix, osteocalcin, and runx2 were increased after BMSC were treated with HAp-1 for 6 days. Although three kinds of HAps treatment for 9 days increased osteorix mRNA expression, osteocalcin, and runx2 mRNA expression levels were upregulated only by HAp-1. Similarly, only HAp-1 enhanced wedelolactone-induced osteocalcin, osteorix, and runx2 mRNA expression after 9 days treatment. Together, these results suggested that HAps with different sizes generated different effect on osteoblastogenesis. HAp-1 combined with wedelolacone can exert an enhanced effect on osteoblastogenesis, which has potential for treating osteoporosis. (c) 2018 Wiley Periodicals, Inc.

AB - Nitric oxide (NO)-generating materials are beneficial for vascular tissue engineering (VTE) scaffold because the produced NO would enhance endothelial cells viability while inhibit smooth muscle cell (SMC) proliferation and reduce platelet adhesion, resulting in ideal hemocompatibility and endothelialization. Herein, poly(epsilon-caprolactone) (PCL)/keratin biocomposite mats were first fabricated, followed by in situ gold (Au) nanoparticles loading to afford PCL/keratin/AuNPs mats. These mats were characterized using field emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), X ray diffraction (XRD), and thermogravimetric analysis (TGA). The PCL/keratin/AuNPs mats were demonstrated to be capable of catalyzing NO release in the mimicked blood microenvironments. The generated NO could enhance human umbilical vein endothelial cell growth and inhibit human umbilical arterial SMC viability. In addition, these mats maintained the antibacterial activity of Au nanoparticles with good blood compatibility. Taken together, these keratin-based composite mats have potential usage in the VTE.

AB - Hypoplastic right heart syndrome (HRHS) is a rare congenital defect characterized by underdeveloped and malformed structures of the right heart. Familial recurrence of HRHS indicates genetic factors contribute to its etiology. Our study investigates the presence of copy number variants (CNVs) in HRHS cases. We genotyped 42 HRHS cases identified from live births throughout California (2003 2010) using the Illumina HumanOmni2.5-8 array. We identified 14 candidate CNVs in 14 HRHS cases (33%) based on the genes included in the CNVs and their functions. Duplications overlapping part of ERBB4 were identified in two unrelated cases. ERBB4 is a neuregulin receptor with a pivotal role in cardiomyocyte differentiation and heart development. We also described a 7.5 Mb duplication at 16q11-12. Multiple genes in the duplicated region have previously been linked to heart defects and cardiac development, including RPGRIP1L, RBL2, SALL1, and MYLK3. Of the 14 validated CNVs, we identified four CNVs in close proximity to genes linked to the Wnt signaling pathway. This study expands on our previous work supporting the role of genetics in HRHS. We identified CNVs affecting crucial genes and signaling pathways involved in right heart development. ERBB4 and duplication of the 16q11-12 region are important areas for future investigation. PMID- 30289600 TI - The characteristics of temper outbursts in Prader-Willi syndrome. AB - The purpose of this study was to develop a comprehensive understanding of temper outbursts in Prader-Willi syndrome (PWS). A survey was developed from interviews conducted with individuals with PWS and their caregivers. The survey was completed by 101 primary caregivers. The findings suggest that outburst frequency decreases with age while duration increases. Adolescents exhibited more severe behaviors than children or adults. No differences were found across gender or genetic subtype. Provocations fit into three themes: goal blockage, social injustice, and difficulty dealing with change. Distracting the person or giving them space to calm down were the only management strategies judged effective. Risperidone, sertraline, and fluoxetine were the most common medications prescribed for outbursts, though parents reported only minor effects. PMID- 30289601 TI - Prenatal profile of Pallister-Killian syndrome: Retrospective analysis of 114 pregnancies, literature review and approach to prenatal diagnosis. AB - Pallister-Killian syndrome (PKS) is a tissue limited mosaic disorder, characterized by variable degrees of neurodevelopmental delay and intellectual disability, typical craniofacial findings, skin pigmentation anomalies and multiple congenital malformations. The wide phenotypic spectrum of PKS in conjunction with the mosaic distribution of the i(12p) makes PKS an underdiagnosed disorder. Recognition of prenatal findings that should raise a suspicion of PKS is complicated by the fragmentation of data currently available in the literature and challenges in diagnosing a mosaic diagnosis on prenatal testing. Ultrasound anomalies, especially congenital diaphragmatic hernia, congenital heart defects, and rhizomelic limb shortening, have been related to PKS, but they are singularly not specific and are not present in all affected fetuses. We have combined prenatal data from 86 previously published reports and from our cohort of 114 PKS probands (retrospectively reviewed). Summarizing this data we have defined a prenatal growth profile and identified markers of perinatal outcome which collectively provide guidelines for early recognition of the distinctive prenatal profile and consideration of a diagnosis of PKS as well as for management and genetic counseling.

PMID- 30289602 TI - Using microarray-based subtyping methods for breast cancer in the era of high throughput RNA sequencing. AB - Breast cancer is a highly heterogeneous disease that can be classified into multiple subtypes based on the tumor transcriptome. Most of the subtyping schemes used in clinics today are derived from analyses of microarray data from thousands of different tumors together with clinical data for the patients from which the tumors were isolated. However, RNA sequencing (RNA-Seq) is gradually replacing microarrays as the preferred transcriptomics platform, and although transcript abundances measured by the two different technologies are largely compatible, subtyping methods developed for probe-based microarray data are incompatible with RNA-Seq as input data. Here, we present an RNA-Seq data processing pipeline, which relies on the mapping of sequencing reads to the probe set target sequences instead of the human reference genome, thereby enabling probe-based subtyping of breast cancer tumor tissue using sequencing-based transcriptomics. By analyzing 66 breast cancer tumors for which gene expression was measured using both microarrays and RNA-Seq, we show that RNA-Seq data can be directly compared to microarray data using our pipeline. Additionally, we demonstrate that the established subtyping method CITBCMST (Guedj et al., ), which relies on a 375 probe set-signature to classify samples into the six subtypes basL, lumA, lumB, lumC, mApo, and normL, can be applied without further modifications. This pipeline enables a seamless transition to sequencing-based transcriptomics for future clinical purposes.

PMID- 30289605 TI - Basan gets a new fingerprint: Mutations in the skin-specific isoform of SMARCAD1 cause ectodermal dysplasia syndromes with adermatoglyphia. AB - Basan syndrome is an autosomal dominant ectodermal dysplasia (ED) with congenital adermatoglyphia, transient neonatal acral bullae, and congenital facial milia. Autosomal dominant adermatoglyphia (ADG) is characterized as adermatoglyphia with hypohidrosis. Recently mutations in the skin-specific isoform of the gene SMARCAD1 have been found in both syndromes. This report proposes to unify these two previously distinct ED, into one syndrome. We offer a new acronym: SMARCAD syndrome (SMARCAD1-associated congenital facial Milia, Adermatoglyphia, Reduced sweating, Contractures, Acral Bullae, and Dystrophy of nails). Sanger sequencing was performed on genomic DNA from a patient with Basan syndrome using primers designed to flank SMARCAD1. Sanger sequencing revealed a novel variant, NM_001254949.1:c.-10 + 2 T > G, in the donor splice site of exon 1 of the skin specific isoform. This variant and the other five previously reported variants in Basan syndrome and ADG are all within the same donor splice site. We conclude that Basan syndrome and ADG are on a phenotypic spectrum of a monogenic syndrome which is better described by the acronym SMARCAD syndrome. PMID- 30289606 TI - Suppressing inflammation and enhancing osteogenesis using novel CS-EC@Ca microcapsules. AB - The aim of this study was to investigate the suppression of inflammation and enhancement of osteogenesis using chitosan-coated calcium hydroxide-loaded microcapsules (CS-EC@Ca microcapsules) in vivo. Circular defects were created in the mandibular bones of rabbits and filled with Ca(OH)2 , Bio-oss, or CS-EC@Ca microcapsules, and rabbits without drug implantation served as the controls. Lipopolysaccharides were injected in situ daily in all groups for 7 days. Mandibular bones were investigated at 4 and 12 weeks after surgery using micro CT, histological observations, and real-time PCR analysis. At the postoperation, there was more substantial nascent bone in the microcapsule and Bio-oss groups than in the control group. The recovery of the rabbits in the Ca(OH)2 group was slower than the control group, as determined using micro-CT and histological staining. Osteocalcin and collagen type I production was not significantly different between the microcapsule and Bio-oss groups (p > 0.05), but the expression levels of the two molecules were significantly increased compared to the control and Ca(OH)2 groups at postoperation (p < 0.05). The mRNA transcript levels of inflammatory factors in the microcapsule group had the most reduced expression of IL-6 and TNF-alpha (p < 0.05). The microcapsules significantly reduced inflammation and promoted osteogenesis in this rabbit model of inflammatory bone destruction. Our findings indicate that CS-EC@Ca microcapsules hold potential for use in apical periodontitis treatment. (c) 2018 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 106A: 3222-3230, 2018. PMID- 30289607 TI - A de novo in-frame deletion of CASK gene causes early onset infantile spasms and supratentorial cerebral malformation in a female patient. AB - We report a female patient with a novel, heterozygous, de novo in-frame deletion in the CASK gene (c.2179-2181 del GTA, p.Val727del) who presents with early onset infantile spasms, hypsarrhythmia on electroencephalogram (EEG), and frontal lobe abnormalities on brain magnetic resonance imaging (MRI) without microcephaly and pontocerebellar hypoplasia. This is the first case report of an in-frame deletion in the CASK gene causing early onset infantile spasms and supratentorial focal brain malformation on brain MRI in the literature. This is also the first report of a female with CASK-related disorder with hypsarrhythmia pattern on EEG. This report expands the clinical phenotypic spectrum in CASK-related disorders in female patients. A heterozygous de novo variant in RORA (c.88 C>G, p.Gln 30Glu) was reported in this patient as a variant of uncertain significance. PMID- 30289608 TI - Stress and sleep remain significant predictors of health after controlling for negative affect. AB - Prior research has shown that the predictive power of a stress-health model can be improved by the addition of sleep as a predictor variable. However, negative affect (NA) may act as a confounding variable in stress-health relationships: a source of bias that potentially inflates the observed relationship between stress and health. The current study examines whether stress and sleep remain significant predictors of health after controlling for trait NA. An online survey containing well-established measures of stress, sleep, health, and NA was completed by 460 undergraduates. Hierarchical regression analyses revealed that stress and sleep remained significant predictors of self-reported health after controlling for the effects of NA. Our findings support the notion that stress health models can be improved by the integration of sleep as an additional predictor variable and demonstrate that the stress/sleep-health relationships are not fully explained by dispositional NA. From a theoretical perspective, the inclusion of NA measures allows researchers to tease apart the unique contributions of predictor variables. This knowledge can subsequently be put to the test with greater confidence in the design of interventions that seek to improve health through stress reduction and improved sleep. PMID- 30289610 TI - Morphological and isotopic changes of heterocystous cyanobacteria in response to N2 partial pressure. AB - Earth's atmospheric composition has changed significantly over geologic time. Many redox active atmospheric constituents have left evidence of their presence, while inert constituents such as dinitrogen gas (N2 ) are more elusive. In this study, we examine two potential biological indicators of atmospheric N2 : the morphological and isotopic signatures of heterocystous cyanobacteria. Biological nitrogen fixation constitutes the primary source of fixed nitrogen to the global biosphere and is catalyzed by the oxygen-sensitive enzyme nitrogenase. To protect this enzyme, some filamentous cyanobacteria restrict nitrogen fixation to microoxic cells (heterocysts) while carrying out oxygenic photosynthesis in vegetative cells. Heterocysts terminally differentiate in a pattern that is maintained as the filaments grow, and nitrogen fixation imparts a measurable isotope effect, creating two biosignatures that have previously been interrogated under modern N2 partial pressure (pN2 ) conditions. Here, we examine the effect of variable pN2 on these biosignatures for two species of the filamentous cyanobacterium Anabaena. We provide the first in vivo estimate of the intrinsic isotope fractionation factor of Mo-nitrogenase (epsilonfix = -2.71 +/- 0.090/00) and show that, with decreasing pN2 , the net nitrogen isotope fractionation decreases for both species, while the heterocyst spacing decreases for Anabaena cylindrica and remains unchanged for Anabaena variabilis. These results are consistent with the nitrogen fixation mechanisms available in the two species. Application of these quantifiable effects to the geologic record may lead to new paleobarometric measurements for pN2 , ultimately contributing to a better understanding of Earth's atmospheric evolution.

AB - A quantitative survey was completed by 103 primary care physicians (PCPs) and 59 cardiologists who regularly prescribed beta-blockers to assess knowledge and use of this heterogeneous drug class for hypertension. More cardiologists than PCPs chose beta-blockers as initial antihypertensive therapy (30% vs 17%, P < 0.01). Metoprolol and carvedilol were the most commonly prescribed beta-blockers. Cardiologists rated "impact on energy" and "arterial vasodilation" as more important than PCPs (P < 0.05/<0.01, respectively). Awareness of vasodilation was greater for carvedilol (52%) than nebivolol (31%). Association between beta blockers and clinical variables included nebivolol with beta1 -selectivity, nebivolol and carvedilol with vasodilation and efficacy in older patients and African Americans, metoprolol with heart rate reduction, and atenolol and metoprolol with weight gain and hyperglycemia. Physicians preferred prescribing beta-blockers with lower risk of incident diabetes. Clinical practice guidelines influenced physician prescribing more than formularies or performance metrics. This survey captures physicians' perceptions/use of various beta-blockers and clinically relevant knowledge gaps. PMID- 30289612 TI - Risk of hepatic neoplasms in Wolf-Hirschhorn syndrome (4p-): Four new cases and review of the literature. AB - Wolf-Hirschhorn syndrome (WHS) is a rare contiguous gene deletion disorder characterized by distinctive craniofacial features, prenatal/postnatal growth deficiency, intellectual disability, and seizures. Various malformations of internal organs are also seen. Neoplasia has not been documented as a typical feature of WHS. We review the three prior reports of hepatic neoplasia in WHS and add four previously unreported individuals. We propose that, in the context of the rarity of WHS, these seven cases suggest that hepatocellular neoplasia may be a feature of WHS. PMID- 30289613 TI - Development of mechanically compliant 3D composite scaffolds for bone tissue engineering applications. AB - Cancellous bone region of the human native bone has the potential to bear significant mechanical loads. However, due to the following parameters such as low trabecular volume, more porosity, less thickness and more interconnectivity, cancellous bone is accessible to damage in accidents or when aging. This research led to the effective fabrication and engineering of cancellous region of the bone for its application in reconstruction or filling of bone voids after resection of large tumor mass. Scaffolds containing hydroxyapatite (HAp), polyvinyl alcohol (PVA) and polyvinyl pyrrolidone (PVP) (5% polymer and HAp concentrations) at different HAp: polymer composite ratios (50:50, 70:30 and 80:20), were fabricated by freeze-drying method using only water as solvent and ribose as crosslinker for the scaffolds. The fabricated scaffolds were characterized for its mechanical (compressive) strength, chemical properties using FT-IR and XRD analyses, swelling and degradation studies, confirmation of mineralization process by immersion in simulated body fluid (SBF) for 7, 15 and 30 days, morphological analysis using scanning electron microscopy (SEM), and biocompatibility properties by performing MTT analysis. From the combined interpretation of the above mentioned tests, it was proven that 80:20 ratio of HAp to polymers was found to be the most suitable scaffold in terms of its optimal properties for its use as bone graft material for trabecular bone.

AB - Severe forms of osteogenesis imperfecta (OI) are usually caused by mutations in genes that code for collagen Type I and frequently are associated with craniofacial abnormalities. However, the dental and craniofacial characteristics of OI caused by the p.Ser40Leu mutation in the IFITM5 gene have not been reported. We investigated a 15-year-old girl with severe OI caused by this mutation. She had marked deformations of extremity long bones. There were no clinical or radiological signs of dentinogenesis imperfecta, but one tooth was missing and several teeth were impacted. Cone beam computed tomography revealed a generalized osteopenic appearance of the craniofacial skeleton, bilateral enlargement of mandibular bodies, and areas of cortical erosions. The cranial base and skull showed a generalized granular bone pattern with a mixture of osteosclerosis and osteolysis. Sphenoid and frontal sinuses were congenitally missing. Cephalometric analysis indicated a Class III growth pattern. In this case, the IFITM5 p.Ser40Leu mutation did not affect tooth structure but was associated with deformities in craniofacial bones that resemble those in the other parts of the skeleton.

AB - DCPS gene encodes for a protein involved in gene expression regulation through promoting cap degradation during mRNA decapping processes. Mutations altering the DCPS function have been associated to a distinct disorder, Al-Raqad syndrome, so far described only in two families. We report on a patient harboring a novel homozygous missense mutation in DCPS, presenting with growth retardation, craniofacial anomalies, skin dyschromia, and neuromuscular defects. This case study explains the molecular spectrum of DCPS mutations and might contribute to the phenotypic delineation of this rare condition. PMID- 30289616 TI - Photoluminescent arginine-functionalized polycitrate with enhanced cell activity and hemocompatibility for live cell bioimaging. AB - Development of biodegradable and highly biocompatible polymer with intrinsical photoluminescence and high photostability for real-time live cell bioimaging has attracted much attention recently. Here, a biodegradable and amphiphilic poly (citrate)-co-poly (ethylene glycol) (PEG) grafted with arginine (PCGA) polymer with intrinsical fluorescence was synthesized for targeted live cell bioimaging. The physicochemical structure, photoluminescent properties, hemocompatibility, cytotoxicity, and fluorescent bioimaging studies in live cells were determined in detail. PCGA showed a significantly high hemocompatibility, low cytotoxicity, and excellent photostability, which allows for imaging the live cells attachment and proliferation. Furthermore, PCGA could efficiently enhance cell attachment and proliferation due to the presence of arginine, suggesting their high cellular biocompatibility. Importantly, PCGA could selectively stain the lysosome in cells. Our results demonstrated that the amino acid-based polymer functionalization may be an important strategy to develop multifunctional biomaterials with enhanced biocompatibility for targeted bioimaging, cancer therapy, and regenerative medicine.

AB - INTRODUCTION: Tuberculosis (TB) is a significant health problem in developing countries. There are limited data on TB among end stage renal disease (ESRD) patients on maintenance dialysis in India. Clinical profile and outcome of TB in dialysis were studied. METHODS: Retrospective study of ESRD patients who were on maintenance dialysis (either peritoneal dialysis [PD] or hemodialysis (HD]) and diagnosed to have TB over a period of 11 years. FINDINGS: Thirty-two patients had a diagnosis of TB. Mean age of the patients was 50.3 +/-13.9 years. The majority (56.2%) of the patients were female. The modality of dialysis was HD in 53.1% and PD in 46.9%. Mean duration of dialysis at the diagnosis of TB was 15.1 +/- 13.9 months. Over three-quarter of the patients had an extrapulmonary involvement. Pleuro-pulmonary (40.6%), peritoneum (34.4%), and lymph node (15.6%) were the most common sites for TB. About 6.3%patients had disseminated TB, and 3.1% had pericardial TB. The clinical presentation of TB was: fever/pyrexia of unknown origin 28.1%, constitutional symptoms of anorexia, fever, night sweats and weight loss 34.4%, abnormal chest radiograph 37.5%, ascites/peritonitis 34.4%, pleural effusion 25%, lymphadenopathy 18.8%, meningoencephalitis 6.3%, and pericardial effusion 3.1%. Peritoneal TB presented as nonresolving peritonitis in PD and ascites in HD. The diagnosis was a microbiological/histological in 50% and rest 50% only on clinical grounds. Nine (29%) patients had adverse effects of anti-TB drugs. Four patients of TB peritonitis had a poor gastrointestinal tolerance of anti-TB drugs and defaulted on the treatment and had an adverse outcome. About 53.1% of the patients survived, and 46.9% died. DISCUSSION: TB in dialysis is mostly extrapulmonary. Early diagnosis is difficult, and the adverse effects of anti-TB medications complicate the treatment. TB in dialysis carries high morbidity and mortality. TB peritonitis has a poor prognosis. PMID- 30289618 TI - HMGA2 as a functional antagonist of PARP1 inhibitors in tumor cells. AB - Poly(ADP-ribose) polymerase 1 inhibitors alone or in combination with DNA damaging agents are promising clinical drugs in the treatment of cancer. However, there is a need to understand the molecular mechanisms of resistance to PARP1 inhibitors. Expression of HMGA2 in cancer is associated with poor prognosis for patients. Here, we investigated the novel relationship between HMGA2 and PARP1 in DNA damage-induced PARP1 activity. We used human triple-negative breast cancer and fibrosarcoma cell lines to demonstrate that HMGA2 colocalizes and interacts with PARP1. High cellular HMGA2 levels correlated with increased DNA damage induced PARP1 activity, which was dependent on functional DNA-binding AT-hook domains of HMGA2. HMGA2 inhibited PARP1 trapping to DNA and counteracted the cytotoxic effect of PARP inhibitors. Consequently, HMGA2 decreased caspase 3/7 induction and increased cell survival upon treatment with the alkylating methyl methanesulfonate alone or in combination with the PARP inhibitor AZD2281 (olaparib). HMGA2 increased mitochondrial oxygen consumption rate and spare respiratory capacity and increased NAMPT levels, suggesting metabolic support for enhanced PARP1 activity upon DNA damage. Our data showed that expression of HMGA2 in cancer cells reduces sensitivity to PARP inhibitors and suggests that targeting HMGA2 in combination with PARP inhibition may be a promising new therapeutic approach.

AB - Insistence on sameness (IS) in individuals with autism spectrum disorder (ASD) and their families may have utility in identifying meaningful subgroups for studying the pathophysiological and genetic pathways affected in ASD. The primary objectives of the current study were to (1) characterize features of IS in parents of children with ASD and (2) examine their relationships with child IS symptoms. Participants were 2760 families who participated in the Simons Simplex Collection. Levels of parent IS were measured using the Broader Autism Phenotype Questionnaire (BAPQ). A factor analysis generated a BAPQ-IS scale, consisting of a subset of 11 items from the original BAPQ-Rigid scale. Correlations were run to examine the relationship between parent BAP and child IS variables. Correlations were found between parent IS and measures of child IS. Although relationships between parent and child IS features were statistically significant in this large sample, effect sizes were small. Results may be reflective of sample design that only included simplex families, where ASD severity may be predominantly driven by spontaneous mutations and less by common inherited risk from parents. In addition, child and parent measures used may have differentially captured features and severity of IS. Further research is needed on how IS can be accurately measured throughout development and across individuals with ASD and their unaffected family members to facilitate future studies on IS as a possible endophenotype for ASD. Autism Res 2018, 11: 1253-1263. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Previous research has suggested that insistence on sameness (IS) may be a heritable trait in autism spectrum disorder (ASD). The study examined whether children with high levels of IS had parents with IS tendencies. A small relationship was found between parent and child measures of IS. Future research is needed on measurement of insistence on sameness across individuals with and without ASD to further examine this relationship and improve understanding of the genetics of ASD.

AB - SCOPE: The prevalence of celiac disease has increased since the last half of the 20th century and is now about 1% in most western populations. At present, people who suffer from celiac disease have to follow a gluten-exclusion diet throughout their lives. Compliance to this restrictive diet is demanding and the development of alternative strategies has become urgent. METHODS AND RESULTS: In this context, it is found that the biocompatible aminopolysaccharide chitosan imposes a different gluten reorganization after gluten redox reaction producing in situ mechanically interlocked supramolecular assemblies between gluten and chitosan. These new structures result in the decrease of gluten digestibility, tissue transglutaminase deamidation activity, and interferon-gamma production in intestinal T cell lines generated from biopsy specimens of celiac disease patients. CONCLUSION: Overall, the results demonstrate the potential of this research avenue to celiac disease is problematic, as the reorganization of gluten proteins to a novel supramolecular architecture shows a positive impact on known pathogenesis mechanisms of the disease. At present, the only therapy for celiac disease is adherence to a gluten-free diet. Here, it is shown that chitosan imposed gluten reorganization to an interlocked self-assembled supramolecular architecture reduces gluten digestibility, R5-reactivity, tissue transglutaminase deamidation activity, and its capacity to stimulate a T-cell-mediated immune response in celiac disease. PMID- 30289621 TI - Measuring costs and quality of life for venous leg ulcers. AB - Venous leg ulcers (VLUs) result in substantial economic costs and reduced quality of life (QoL); however, there are few Australian cost estimates, especially using patient-level data. We measured community-setting VLU management costs and the impact on the QoL of affected individuals. VLU patients were recruited from a specialist wound clinic, an outpatient clinic, and two community care clinics in Queensland. Cost data were collected at the baseline visit. QoL (EQ-5D-5L) and wound status data were collected at baseline, 1, 3, and 6 months. Patients were classified into guideline-based/optimal care and usual care groups. Average weekly costs per patient were statistically significantly different between the usual care and optimal care groups-$214.61 and $294.72, respectively (P = 0.04). Baseline average QoL score for an unhealed ulcer was significantly higher in the optimal care group compared with usual care (P = 0.025). Time to healing differed between the usual care group and the optimal care group (P = 0.04), with averages of 3.9 and 2.7 months, respectively. These findings increase the understanding of the costs, QoL, and healing outcomes of VLU care. Higher optimal care costs may be offset by faster time to healing. This study provides data to inform an economic evaluation of guideline-based care for VLUs. PMID- 30289622 TI - The birth prevalence, severity, and temporal trends of congenital heart disease in the middle-income country: A population-based study. AB - OBJECTIVES: There is limited data on congenital heart disease (CHD) from the lower- and middle-income country. We aim to study the epidemiology of CHD with the specific objective to estimate the birth prevalence, severity, and its trend over time. DESIGN: A population-based study with data retrieved from the Pediatric Cardiology Clinical Information System, a clinical registry of acquired and congenital heart disease for children. SETTING: State of Johor, Malaysia. PATIENTS: All children (0-12 years of age) born in the state of Johor between January 2006 and December 2015. INTERVENTION: None. OUTCOME MEASURE: The birth prevalence, severity, and temporal trend over time. RESULTS: There were 531,904 live births during the study period with 3557 new cases of CHD detected. Therefore, the birth prevalence of CHD was 6.7 per 1000 live births (LB) (95% confidence interval [CI]: 6.5-6.9). Of these, 38% were severe, 15% moderate, and 47% mild lesions. Hence, the birth prevalence of mild, moderate, and severe CHD was 3.2 (95% CI: 3.0-3.3), 0.9 (95% CI: 0.9- 1.1), and 2.6 (95% CI: 2.4-2.7) per 1000 LB, respectively. There was a significant increase in the birth prevalence of CHD, from 5.1/1000 LB in 2006 to 7.8/1000 LB in 2015 (P < .0001) due to increase in detection of both mild (1.9/1000 LB in 2006 to 3.9/1000 LB in 2015, P < .001) and severe CHD (1.8/1000 LB in 2005 to 2.9/1000 LB in 2015, P < .001). CONCLUSIONS: The birth prevalence of CHD was 6.7 per 1000 live births, and two in five were severe and significantly associated with syndrome and extracardiac defect. There was a significant increase in the detection of severe lesions in recent years leading to more burden to resources that are already limited in the middle-income country. Therefore, strategic and comprehensive pediatric and congenital heart surgery program is required. PMID- 30289623 TI - Application of solid-phase microextraction in current biomedical research. AB - Extraction of endogenous compounds and drugs and their corresponding metabolites from complex matrices, such as biofluids and solid tissues, requires adequate analytical approach facilitating qualitative and quantitative analysis. To this end, solid-phase microextraction has been introduced as modern technology that is capable of efficient and high-throughput extraction of compounds due to its ability to amalgamate sampling, extraction, and pre-concentration steps, while requiring minimal use of organic solvents. The ability of solid-phase microextraction to enable analyses on small-volume biological samples and growing availability of biocompatible solid-phase microextraction coatings make it a highly useful technology for variety of applications. For example, solid-phase microextraction is particularly useful for identifying biomarkers in metabolomics studies, and it can be successfully applied in pharmaceutical and toxicological studies requiring the fast and sensitive determination of drug levels, especially those that are present at low levels in biological matrices such as plasma, urine, saliva, and hair. Moreover, solid-phase microextraction can be directly applied in in vivo studies because this extraction technique is non-exhaustive and its biocompatible probes offer minimal invasiveness to the analyzed system. In this article, we review recent progress in well-established solid-phase microextraction technique for in vitro and in vivo analyses of various metabolites and drugs in clinical, pharmaceutical, and toxicological applications. PMID- 30289624 TI - A prediction tool for hospital-acquired pressure ulcers among surgical patients: Surgical pressure ulcer risk score. AB - Surgical patients are prone to developing hospital-acquired pressure ulcers (HAPU). Therefore, a better prediction tool is needed to predict risk using preoperative data. This study aimed to determine, from previously published HAPU risk factors, which factors are significant among our surgical population and to develop a prediction tool that identifies pressure ulcer risk before the operation. A literature review was first performed to elicit all the published HAPU risk factors before conducting a retrospective case-control study using medical records. The known HAPU risks were compared between patients with HAPU and without HAPU who underwent operations during the same period (July 2015 December 2016). A total of 80 HAPU cases and 189 controls were analysed. Multivariate logistic regression analyses identified eight significant risk factors: age >= 75 years, female gender, American Society of Anaesthesiologists >= 3, body mass index < 23, preoperative Braden score <= 14, anaemia, respiratory disease, and hypertension. The model had bootstrap-corrected c-statistic 0.78 indicating good discrimination. A cut-off score of >=6 is strongly predictive, with a positive predictive value of 73.2% (confidence interval [CI]: 59.7%-84.2%) and a negative predictive value of 80.7% (CI: 74.3%-86.1%). SPURS contributes to the preoperative identification of pressure ulcer risk that could help nurses implement preventive measures earlier.

PMID- 30289627 TI - Rapid therapeutic advances in CFTR modulator science. AB - Cystic fibrosis (CF) is an autosomal recessive genetic disease caused by variants in the gene encoding the cystic fibrosis transmembrane conduction regulator (CFTR) protein. Loss of CFTR function disrupts chloride, bicarbonate and regulation of sodium transport, producing a cascade of mucus obstruction, inflammation, pulmonary infection, and ultimately damage in numerous organs. Established CF therapies treat the downstream consequences of CFTR dysfunction and have led to steady improvements in patient survival. A class of drugs termed CFTR modulators has recently entered the CF therapeutic landscape. These drugs differ fundamentally from prior therapies in that they aim to improve the function of disease-causing CFTR variants. This review summarizes the science behind CFTR modulators, including their targets, mechanism of action, clinical benefit, and future directions in the field. CFTR modulators have dramatically changed how CF is treated, validated CFTR as a therapeutic target, and opened the door to truly personalized therapies and treatment regimens. PMID- 30289625 TI - Variance of IQ is partially dependent on deletion type among 1,427 22q11.2 deletion syndrome subjects. AB - The 22q11.2 deletion syndrome is caused by non-allelic homologous recombination events during meiosis between low copy repeats (LCR22) termed A, B, C, and D. Most patients have a typical LCR22A-D (AD) deletion of 3 million base pairs (Mb). In this report, we evaluated IQ scores in 1,478 subjects with 22q11.2DS. The mean of full scale IQ, verbal IQ, and performance IQ scores in our cohort were 72.41 (standard deviation-SD of 13.72), 75.91(SD of 14.46), and 73.01(SD of 13.71), respectively. To investigate whether IQ scores are associated with deletion size, we examined individuals with the 3 Mb, AD (n = 1,353) and nested 1.5 Mb, AB (n = 74) deletions, since they comprised the largest subgroups. We found that full scale IQ was decreased by 6.25 points (p = .002), verbal IQ was decreased by 8.17 points (p = .0002) and performance IQ was decreased by 4.03 points (p = .028) in subjects with the AD versus AB deletion. Thus, individuals with the smaller, 1.5 Mb AB deletion have modestly higher IQ scores than those with the larger, 3 Mb AD deletion. Overall, the deletion of genes in the AB region largely explains the observed low IQ in the 22q11.2DS population. However, our results also indicate that haploinsufficiency of genes in the LCR22B-D region (BD) exert an additional negative impact on IQ. Furthermore, we did not find evidence of a confounding effect of severe congenital heart disease on IQ scores in our cohort. PMID- 30289630 TI - Tobacco Smoking and Psychotic-Like Experiences in a General Population Sample. AB - OBJECTIVE: Recent findings suggest an association between tobacco and psychosis, but whether this association is mediated by confounding factors is unknown. Psychosis-like experiences (PLEs) are a subclinical expression of psychosis. To disentangle the association of tobacco with PLEs, we examined data from a large US population-based, nationally representative sample. METHODS: Analysis was conducted on Wave 2 of the National Epidemiologic Survey of Alcohol and Related Conditions (N = 34,653 adults, conducted from 2004 to 2005). Participants were assessed with the Alcohol Use Disorder and Associated Disabilities Interview Schedule-IV. Twenty-two PLEs previously described as observed indicators of psychosis were used. Participants were stratified according to their smoking status (never/former/current) for 5 different types of tobacco. RESULTS: There was a significant association (ie, with 95% CIs for which the lower value was >= 1) between smoking status and 14 of the 22 assessed PLEs. These associations remained significant after adjustment for sociodemographic variables (including urbanicity or ethnicity), lifetime drug use disorder, and past-year cannabis use. While 26.33% of nonsmokers reported at least 1 PLE, this prevalence was slightly higher in former smokers (27.48%) and rose as high as 39.09% in current smokers (for current smokers vs lifetime abstainers, adjusted OR = 1.33; 95% CI, 1.23 1.45). All 22 PLEs had higher prevalence in smokers than in former smokers or lifetime abstainers. A total of 8.56% of smokers reported at least 5 PLEs, compared to 3.42% in lifetime abstainers (aOR = 1.56; 95% CI, 1.32-1.84). CONCLUSIONS: In a large population-based, nationally representative sample, smoking status was associated with various PLEs. This association was not explained only by other known risk factors of PLEs or schizophrenia. There is a need to identify the potential neurobiological mechanisms by which smoking and PLEs are associated, for patients and from a public health perspective. PMID- 30289629 TI - Suicide Methods and Specific Types of Accidental Death and Fatal Poisoning Among Discharged Psychiatric Patients: A National Cohort Study. AB - OBJECTIVE: Persons discharged from inpatient psychiatric units are at greatly elevated risk of dying unnaturally. We conducted a comprehensive examination of specific causes of unnatural death post-discharge in a national register-based cohort. METHOD: A cohort of 1,683,645 Danish residents born 1967-1996 was followed from their 15th birthday until death, emigration, or December 31, 2011, whichever came first. Survival analysis techniques were used to estimate incidence rate ratios (IRRs) comparing risk for persons with and without psychiatric admission history in relation to (a) suicide method, (b) accidental death type, (c) fatal poisoning type, and (d) homicide. RESULTS: More than half (52.5%, n = 711) of all unnatural deaths post-discharge were fatal poisonings, compared with less than a fifth (17.0%, n = 1,012) among persons in the general population not admitted. Just 6.8% (n = 92) of all unnatural deaths post discharge were due to transport accidents-the most common unnatural death type in the general population (53.4%, n = 3,184). Suicide risk was 32 times higher among discharged patients (IRR 32.3; 95% CI, 29.2-35.8) and was even higher during the first year post-discharge (IRR 70.4; 95% CI, 59.7-83.0). Among the suicide methods examined, relative risk values were significantly larger for intentional self-poisoning (IRR 40.8; 95% CI, 33.9-49.1) than for "violent" suicide methods (IRR 29.4; 95% CI, 26.1-33.2). The greatest relative risk observed was for fatal poisoning (irrespective of intent) by psychotropic medication (IRR 93.7; 95% CI, 62.5-140.5). The highest post-discharge mortality rate was for accidental self poisoning among persons diagnosed with a psychoactive substance abuse disorder: 290.1 per 100,000 person-years. CONCLUSIONS: Closer liaison between inpatient services and community care, more effective early treatment for comorbid substance abuse, enhanced psychosocial assessment following self-harm, and tighter medication surveillance could decrease risk of unnatural death post discharge. PMID- 30289631 TI - Safety of Pregabalin in Pregnancy. AB - In different parts of the world, pregabalin is an approved treatment for neuropathic pain syndromes, fibromyalgia, partial-onset seizures, and generalized anxiety disorder. Few studies have examined the safety of pregabalin exposure during pregnancy. Among 4 studies identified through a PubMed search conducted in September 2018, one small study (exposed n = 30) recorded a major malformation rate of 3.3%, which was similar to that in unexposed controls. Another small study (exposed n = 30) recorded increased rates of spontaneous abortion (23.3%), preterm birth (25.0%), and major malformations (7.7%), none of which reached statistical significance even in unadjusted analyses. A third study (exposed n = 116) identified a significantly increased rate of major malformations (6.0%) but no increase in the rates of other adverse birth outcomes. The fourth and largest study (exposed n = 477 and n = 174; 2 datasets), which also presented the best statistical analysis, found no increase in the major malformation risk associated with pregabalin exposure. A subjective conclusion is that there is no clear signal that pregabalin exposure during pregnancy is associated with adverse gestational outcomes; however, this conclusion is limited by the consideration that all analyses were underpowered. Pregabalin use in pregnancy is therefore best restricted to circumstances in which the risk-benefit ratio is clearly favorable, and then, only after shared decision-making.

AB - As healthcare professionals, we deal daily with "aging"'factors relating to our patients' dental treatment planning (and to ourselves). We are all are expressions of our DNA-the long molecules in our cells' nuclei that contain our genes which determine how proteins will be made to express who we are. Although genetics can be a confusing subject to understand, when trying to understand DNA, perhaps consider that you Do Not Abandon learning some of the basics of genetics. In today's evolving world of medical science, there is a major focus on genetics and genomics; analyzing one's genetic makeup to help in diagnosing and managing disease, and prescribing of medications (pharmacogenetics/pharmacogenomics). One aspect of interest is what we call "aging" or getting older, an expression of cellular "senescence"-most of our cells are programmed to commit suicide (apoptosis) over time. So we get wrinkles, our stomach sags and our hair goes gray. As described below, a normal physiologic process takes place at the end of your chromosomes to protect them. Over many years, this process can no longer protect your chromosomes and the cells die. However, if normal processes are not functioning correctly, the chromosomes continue to reproduce-if this is a cancer cell, the lack of cell suicide allows tumors to grow.

AB - It has been suggested that circulating immune complexes containing low density lipoproteins (LDL-CIC) play a role in atherogenesis and are involved in the formation of early atherosclerotic lesions. The complexes, as well as anti-LDL antibody were found in the blood of patients with atherosclerotic process in various cardiovascular diseases, well as in the blood of animals with experimentally modulated atherosclerosis. One can assume that the presence anti LDL antibodies in blood is a result of an immune response that is induced by modification of lipoproteins. LDL-CIC differ from native LDL in many aspects. They have much lower levels of sialic acid, a smaller diameter and a higher density electronegativity than native LDL. The fraction of the LDL-CIC in serum is an important manifestation of the atherosclerotic process. LDL-CIC, unlike the native LDL is able to induce intracellular accumulation of neutral lipids, especially esterified cholesterol in cell cultures obtained from healthy human aortic intima and macrophages in culture. After removal of the LDL-CIC, the serum of CHD-patients loses its atherogenic properties. The titer of the LDL-CIC in the blood serum significantly correlate with the progression of atherosclerosis and in vivo has the highest diagnostic yield of measured among other lipid parameters. Increasing CIC- cholesterol could also increase the risk of coronary artery atherosclerosis. PMID- 30289643 TI - [Obesity: the modern view of a problem]. AB - The article is a review of recent epidemiological observations concerning the prevalence of overweight and obesity in different countries among people of different gender, age. social and ethnic groups. It also presents and analyses health risks and comorbidities leading to disability and death as reported by domestic and foreign researchers. It was found that obesity has multifactorial pathogenesis directly related to energy balance, consumed and expended calories. The need of a multidisciplinary approach to the treatment and prevention of the disease is emphasized taking into consideration the influence of the environment and increasing urbanization on the development of the pathology as well as the role of government efforts to stimulate physical activity of the population in the framework of integral interdisciplinary programs and control over the quality of food. The priority areas for the correction of overweight include optimization of motor activity and diet correction.

AB - The review describes peculiarities of the choice of time and methods of osteosynthesis offemur fractures of different localization in patients with multiple injuries in accordance with modern concepts of treatment of severe multiple and associated lesions. Analysis of domestic and foreign literature shows that earlyfixation of the femur in case of polytrauma can reduce the mortality rate associated with complications and improve the functional outcome. Terms of osteosynthesis of the femur in polytrauma should be chosen taking into account the severity of the injury, the patient's condition, and the period of traumatic disease. The procedure of osteosynthesis must not be a threat to the clinical condition. The choice of the method for fixation of the femur depends of fracture type and location, the presence of fractures in the adjacent and remote segments. The minimally invasive techniques of osteosynthesis of the femur and staged surgical treatment of the victims in an unstable state should be chosen for the treatment of multiple injury in accordance with the concept of "Damage Control Orthopedics".

AB - The knowledge of blood types frequency in hospital patients helps to plan and perform transfusion therapy at blood donor centers. The distribution of patients' blood by ABO groups and RhD allows to more efficiently organize and use donor blood banks. The risk of a disease is related to genome composition and is inherited with an ABO blood type. Every person should know his (her) ABO blood type and RhD to enable early identification of the first symptoms of an illness. Materials and methods. This work is based on the study of 4831 blood samples from patients treated at the Center of Cardiovascular Surgery in 2013 (2885 (59,7%) men of the mean age 55 years and 1946 (40,3 %) women of the mean age 57 years). Results. Type A blood occurred most frequently (1787 or 37,0% samples) followed by group O (1625 or 33,6% samples). Samples of group B made up 1025 of the total (21,2%), AB blood group was found in 394 samples (8,2%). Conclusion. The blood types distribution of the ABO system in the patients treated at the Center of Cardiovascular Surgery was characterized by the following pattern: A > O > B > AB. Group A was identified in 37,0% of the patients. Its frequency is similar to that in the population of the western part of Russia and Moscow but different from that in the people living in nearby regions. The frequency of RhD system antigens is comparable in all regions of Russia. CcDEe, ccDEe, CcDee, CCDee are considered to be the most widespread phenotypes. The residents of the Krasnoyarsk region and some nearby regions having blood type A apply to the Center of Cardiovascular Surgery with cardiovascular disorders more frequently than those with others ABO blood types. PMID- 30289647 TI - [The prognostic value of transient arterial hypertension in patients with chronic heart insufficiency and preserved left ventricular ejection function]. AB - : There is a J-like dependence of mortality among patients with chronic heart insufficiency (CHI) on arterial pressure (AP). This implies the possibility of not only elevation but also fall of AP in such patients. The aim of the study was to determine the frequency and prognostic value of arterial hypotension episodes in CHI patients with preserved left ventricular ejection function (CHI-PEF). . Materials and methods: The study included 169patients (74 men and 95 women) with CHI (mean age 56,3+/-10,9 yr). All of them had PEF higher than 50%. 105 patients had FCII CHI, 64 ones FCIII CHI. Stage IIA was documented in 136 and stage IIB in 33 patients. Duration of the study 24 months. The combined end point included non fatal myocardial infarction and cardiovascular death. Results: Arterial hypotension at office AP was diagnosed in 16 (9,5%) patients, transient arterial hypotension based at 24 hr AP monitoring in 104 (61,6%) patients. A total of 8 combined end points were documented during the study period. All these patients had transient systole-diastolic and/or systolic arterial hypotension . No myocardial infarction or lethal outcome developed in CHI patients without episodes of arterial hypotension (x=4,28, r=0,04). Conclusion: 24 hr AP monitoring in CHI-PEF patients permits to significantly increase the frequency of detection ofpotentially dangerous changes of AP. Transient arterial pressure occurs in 61.6% of the FCII-III CHI-PEF patients. Transient systole-diastolic arterial hypotension significantly increases the risk of non-fatal myocardial infarction and cardiovascular death in CHI-PEF patients PMID- 30289648 TI - [Diurnal rhythm of arterial pressure in patients with acromegaly]. AB - 24 hr monitoring of arterial pressure (AP) in 46 patients with acromegaly in active phase revealed systolic-diastolic arterial hypertension.

PMID- 30289649 TI - [Pulmonary function in patients with type 2 diabetes and coronary artery disease]. AB - : Currently, there is no convincing evidence of respiratory failure in patients with diabetes mellitus (DM) and coronary artery disease (CAD). Aim: To evaluate the differences in the main parameters of pulmonary function in patients with isolated type 2 diabetes and diabetic patients with CAD. Materials and methods: Patients with diabetes were allocated to two groups depending to the presence of CAD. The assessment of carbohydrate and lipid metabolism, as well as the measurement of inflammatory markers were performed using standard methods of clinical and biochemical analysis. Respiratory function and diffusion capacity of the lungs (DLCO) were assessed using a body plethysmograph Elite Dl-220v. Results: Main pulmonary functional test parameters were within normal values, except residual volume in diabetic patients. Patients with concomitant CAD demonstrated lower values of the studied parameters compared to non-diabetic ones. A number of volume and flow rate parameters as well as DLCO correlated with systemic inflammation, decompensation of carbohydrate and lipid metabolism, and duration of diabetes. Conclusion: Diabetic patients with CAD suffered from respiratory failure, manifested as decline in pulmonary function and DLCO. Blood glucose levels, inflammation symptoms, dyslipidemia and myocardial dysfunction are among suspected causes contributing to the development and acceleration of this decline. PMID- 30289650 TI - [Respiratory sleep disorders in vehicle drivers]. AB - Aim: To determine the frequency of respiratory sleep disorders (RSD) in vehicle drivers, peculiarities of their clinical status and workability. Material and methods: The study included the main group of 106 vehicle drivers (VD) and control group of 104 of subjects of other professions. The following methods were used: fibrooptic endoscopy, standard questionnaire, pulsoxymetry, 24 hour blood pressure and ECG monitoring, psychophysiological testing of 86 VD with RSD, arterial hypertension with and without complications. Results: The clinical and instrumental signs of RSD were found in 65.1% VD of the main group and 47,1% of controls. Transitory ischemic attacks, cardiac arrhythmias and their combination occurred more frequently in VD (82.6, 59.2, and 52.2% respectively) than in controls (51.0, 44.8, and 32.6%). In most observations of VD, the smoking rate (98.1%), alcohol intake (95.3%), increased body mass (74.5%), obese (21,7%) dyslypoproteidemia (73.6%), left ventricular hypertrophy (54.7%) and arterial hypertension (57.5%) were significantly higher than in controls : S (76.9%), AI (75.0%), IBM (56.7%), O (18.3%), DLP (59.6%), LVH (41.3%), AH (39.4%). Chronic obstructive pulmonary diseases was diagnosed in 55.6% of VD and 51.9% of controls, diabetes mellitus in 34.9% and 20.2%, epidemiological forms of ischemic heart disease in 22.6% VD and 20.2% controls. Psychophysilogical testing of VD group revealed deterioration of professional qualities and functions of the drivers with respiratory sleep disorders. Conclusion: Significant frequency of RSD among VD (65.1%) in comparison with subjects of other professions (47.1%) was documented.

AB - We studied relative content of CD14+HLA-DR in 214 patients including those with aseptic instability and stable implants of the knee and the hip, periprosthetic infection of the hip, chronic posttraumatic osteomyelitis of long tubular bones, and osteomyelitis generalization (sepsis). We determined HLA-DR expression on monocytes by laser flow cytofluorometry using Beckman Coulter Epics XL (USA) cytometer and monoclonal antibodies (Immunotech Company, France). It has been demonstrated, that the decrease in HLA-DR expression on monocytes can be one of the mechanisms of increasing immune disorders in patients with orthopedic pathology and monitoring HLA-DR monocytic expression can be used as a prognostic criterion of developing pyoinflammatory processes at the stages of surgical treatment.

AB - Antiphospholipid syndrome (APS) is one of the important but poorly known conditions. Its symptoms are ofparticular interest for neurologists since thrombi are most often localized in the cerebral blood vessels which leads to ischemic cerebrovascular accidents (AICS). APS can also manifest itself in the following symptoms: epileptic attacks, dementia, headache, chorea, peripheral neuropathy, myelo- and encephalopathy phenomenologically similar to multiple sclerosis. This article presents a clinical case of secondary APS with the neurological manifestations in a 25-year-old female patient.

AB - The literature data on the effectiveness of remote ischemic preconditioning (RIP) in the prevention of lung injury are contradictory. Authors of some works argue that RIP prevents lung damage during surgical interventions, the authors of other publications claim that the RIP does not protect lung against pathological processes. It is obvious that there is an urgent need for multicenter, randomized trials aimed at studying RIP protective effects against pathological processes in lung. Also required is clinical evaluation of the effectiveness of RIP in the thromboembolism of pulmonary arteries, the transplantation of the lungs and intestinal infarction. Remote preconditioning prevents the intestine injury associated with abdominal aortic aneurysm repair. Experimental data indicate that RIP has the hepatoprotective effect during ischemia and reperfusion injury of liver, septic or haemorrhagic shock. The question of whether the DIP has a protective effect during ischemia-reperfusion of the pancreas remains open.

AB - This review provides an outline of circadian disorders associated with neurodegenerative diseases of the brain in the elderly, including Alzheimer's (AD) and Parkinson's diseases (PD). Since light is one of the most powerful environmental cues synchronizing physiological rhythms, exposure to bright light is often used to treat sleep disorders, behavior of patients with severe dementia, gait, and other functions disordered in CNS pathologies. Photobiomodulation effects of the low-energy laser and LED radiation is also considered as a potential tool for the rehabilitation of patients with various pathologies. It yielded positive results in the treatment of both PD and AD. An external factor that can exacerbate a course of neurodegenerative diseases is light pollution. Irrational artificial lighting can cause jet lag, affect visual and cognitive functions. The review also summarizes the current understanding of fractal dynamics of physiological rhythms in healthy subjects (including brain activity) and their reduced complexity in pathological conditions. The loss of multiscale complexity of brain electrical activity has been documented for patients with AD, PD, epilepsy, and schizophrenia. It is thought to reflect fundamental changes in the regulation of the body's circadian rhythms. Recently, M.V Zueva proposed and theoretically substantiated the hypothesis that allows taking another look at the prospects for the use of light stimulation. It is expected that the use of stimuli with fractal structure can help to restore the retina and brain's functions in neurodegenerative diseases by reactivation of neuronal plasticity and be an innovative method for the treatment of neurodegenerative disorders.

AB - : The article considers the influence of arterial hypertension on the frequency of intra-atrial thrombosis in patients with atrial fibrillation (AF) of non valvular etiology. Materials and methods: 38 patients were examined (26 men and 12 women) aged 35 to 75 years with documented AF. Paroxysmal AF was diagnosed in 10 patients (26.32%). The persistent and permanent forms of arrhythmia were revealed in 14 cases (36.84%). Stage II-III hypertensive disease (HD) was diagnosed in 27 patients (71.1%). The transthoracic and transesophageal echocardiography was performed with the use of ultrasonic devices such as Aloka SSD-4000 ProSound (Japan) and PhilipsIE 33 (USA). Results: The analysis of results of echocardiography (both transthoracic and transesophageal) made it possible to detect intra-atrial clots in 54,8% of the patients with AF of non valvular etiology. Atrial cavity thrombosis was registered in 15 of the 22 cases (68,2%) among the patients with hypertension as a direct cause of AF or another concomitant pathology. Lower blood flow velocity from the left atrial appendage was registered in hypertensive patients compared to those without hypertension - 29.0 (4.2) and 35.4 respectively (8.1) mm/s (p = 0.038; Student's t-test). The reduction of the peak bloodflow velocity in the left atrial appendage was proportional to the increase of hypertension (R = -0,861; p <0,001; R - Spearman's coefficient). The frequency of intra-atrial thrombosis did not depend on the form of atrialfibrillation and duration of the arrhythmic anamnesis. Conclusion: Hypertension is an independent predictor of thromboembolic complications in atrial fibrillation of non-valvular etiology.

Objective: To show the interdependence of this condition and mental disorders and their relation to disturbances of melatonin production . Materials and Methods: 15 patients with seasonal DU and 15 healthy subjects of the control group were examined during 3 years using laboratory, endoscopic, and standard psychodiagnostic methods. Results. It was found that all patients with exacerbation of DU experienced enhanced anxiety, reduced background mood, and impaired quality of life based on general health and mental health scoring scales. The circadian rhythm of melatonin production was markedly distorted throughout the observation period but especially during exacerbations of the disease. Conclusions. The results indicate a high degree of correlation between DU and mental disorders caused by impaired production of melatonin. It suggests common etiological mechanisms of DU and psychosomatic symptom complex. PMID- 30289664 TI - [Biliary reflux-gastritis: etiology, pathogenesis and modern principles of treatment].

AB - Background: The aim of the present article was to report our experience with the treatment of patients with hallux valgus and to perform comparative analysis of the results of the newly proposed and standard methods for its surgical correction. Methods: The data on 70patients (101 feet) with hallux valgus that were operated on between 2011 and 2015 in St. Petersburg Hospital No 2 using the new and standard methods were analysed. The functional assessment (AOFAS score) and X-ray examination were performed preoperatively, 3 and 12 months after the procedure. Comparative analysis between patients undergoing surgical correction by the new and standard methods has been undertaken. Results: We did not find any significant difference between the two groups in mean AOFAS score 12 months after surgery. Nevertheless, the function score of the patients treated by the newly proposed method (79.4+/-6.5 in 3 months) was significantly better than in those given the standard treatment (72.2+/-7.6 in 3 months). Mean intermetatarsal angle 12 months after surgery by standard and new methods was 9,7+/-0,7 degrees and 8,6+/-0,7 degrees (p<0.05), mean metatarsophalangeal angle 13,6+/-0,9 degrees and 13,0+/-1,1 degrees (p<0,05) respectively. Conclusion: According to the data obtained, the original method of hallux valgus surgical correction allows to improve its functional and x-ray results.

AB - The aim of the study was to compare the incidence, onset, and the course of acute myocardial infarction (AMI) among the population of Tomsk in 1984 and 2013. Materials and Methods: The study was based on the analytic database of the World Health Organization epidemiology program AMI Registry (RAMI). Epidemiology of AMI was studied among the urban population aged 20 years and older. A total of 739 and 983 AMI cases were analyzed in 1984 and 2013 respectively. Results: The proportion ofpatients older than 60 years significantly increased in the age structure of AMI patients during the study period. The occurrence of AMI with atypical clinical onset increased by three times; anamnestic background of AMI worsened; and the number of episodes with preinfarction angina increased. Analysis of the AMIpicture revealed an increase in the occurrence of Q (QS)-wave myocardial infarction and a significant rise in the frequency of complications; the frequency of chronic heart failure, cardiac arrhythmias, and recurrent AMI was especially high. Conclusion: An increase in the proportion of elderly and senile people in the age structure resulted in an aggravation of the diagnostic and prognostic features of AMI during the study period. Evidently, the existing situation requires optimization of medical assistance for patients of older age groups with emphasis on the development and the implementation of recommendations concerning the prediction, diagnosis, treatment, and rehabilitation of these patients.

AB - Clinical rhetoric is a science concerned with consistent patterns of speech behavior in different situations of interaction with colleagues, patients, and specialists in various disciplines with a view to extending their practical applications for the enhancement of efficiency of meaningful contacts. The history of this science as a means of rational communication with patients and medical profession dates back to the times of Hippocrates. Its importance greatly increased under the present-day conditions of high-technology and therapeutically aggressive medicine. Clinical rhetoric is based on the principles of general rhetoric. A clinician must be prepared for he fruitful and constructive relations with a variety of partners including patients, healthy subjects, administrators, lawyers, businessmen, and colleagues. Four main peculiarities of clinical rhetoric are distinguished: any debate is possible only in the form of discussion, both the form and content of the opponent's arguments should be treated with respect, the speaker must himself draw attention to the weak points of his theses, all discussions must have the form of a "captain council" in which the shipboy is the first and the captain the last to speak. Traditional forms of clinical discussion include counselling, doctor's rounds, consilia, and demonstrations. Collective forms of stimulating creative thinking, such as brainstorming and foresight have especially good prospects. These approaches appear to be of special value for the solution of heuristic problems. Teaching clinical rhetoric should be initiated since term IV when students begin to understand the role of a doctor as a key figure in the organization of the diagnostic and therapeutic process. Further development of Hippocrates' traditions of collective communication may significantly promote the intellectual return from clinical and scientific discussions in medicine.

PMID- 30289671 TI - [Clinical significance of heart rhythm variability in patients with gastroesophageal reflux disease]. AB - Cardiac manifestations of gastroesophageal reflux disease (GERD) including retrosternal pain and cardiac rhythm disorders were often mentioned in early publications. However, classification of GERD adopted at the 2005 Montreal congress does not include such conditions. Non-coronarogenic pain in the thoracic cage is recognized to be a typical esophageal syndrome while the reflex spasm of coronary arteries and cardiac rhythm disorders associated with GERD should be regarded as manifestations of comorbidity of GERD and cardiovascular diseases. Arrhythmias occur in 30% of patients with GERD, but relevant therapeutic and preventive modalities are poorly developed. Nor are there reliable predictors of arrhythmias. An important role in their pathogenesis in patients with GERD is played bydisbalance of sympathetic and parasympathetic components of vegetative nervous system (VNS). One of the approaches to studying this issue is the analysis of heart rhythm variability (HRV). We consider basic principles of clinical interpretation of the results of HRV research that allow to evaluate the state of VNS and interaction of its components. Analysis of recent publications gives evidence that many HRV parameters depend not only on the balance between components of VNS as was believed by earlier authors (for the lack of their reciprocal relationship) but also on the activity of these components. Other modulating factors include the heart rate, respiratory pattern, intrathoracic pressure, and diastolic atrial extension. We report the results of HRV assessment in patients with GERD that illustrate heart rhythm rigidity and predominant disorders of activity of the parasympathetic component of VNS especially well apparent in patients with erosive reflux esophagitis. However, other authors demonstrate oppositely directed changes and the involvement of the sympathetic component. A possible cause of this discrepancy is factors other than VNS influencing HRV. It is concluded that analysis of HRV can be used to develop a method for the prevention of GERD-associated arrhythmia. The diagnostic value of such method is limited and requires new algorithms for data interpretation taking account of their multifactorial origin. PMID- 30289672 TI - [Atheromatosis of arterial intima]. AB - Phylogenetically late arterial intima of the elastic type contains no proteins for the transfer of ligandless oxidized low density lipoproteins (LDLP) for sedentary macrophages adsorbed on the matrix. Phylogenetically early cells realize the extracellular digestive reaction by releasing proteolytic enzymes (metalloproteinases) into intimal matrix that hydrolize matrix proteoglycans, adsorbed ligandless LDLP, detritus, and complete lysosomal hydrolysis of the most hydrophobic polyenic cholesterol esters (poly-ECS). Smooth muscle cells migrate from the middle muscular layer of the arterial wall, change their contractile phenotype to secretory one, and synthesize in situ de novomatrix proteoglycans. The arterial wall has three layers (monolayer endothelium, intimal media (smooth muscle cells), and adventitia) only in elastic type arteries. It is desirable to elucidate functional differences between phylogenetically early sedentarymacrophages and monocytes-macrophages of later origin and understand whether theydepends on specific features of activity of scavenger eceptors, CD36 translocases, expression of acid hydrolases synthesis for poly-ECS or realization of the extracellular digestion reaction. We believe that formation of atheromatous masses takes place in the matrix of arterial intima rather than in lysosomes taking into account limited possibilities for monocytes-macrophages to realize endocytosis of ligandless LDLP from the matrix. Given that atheromatosis is a syndrome of deficit of essential polyenic fatty acids (PFA) in the cells, intimal atheromatosisshould be regarded only as partial utilization of excess PFA in the matrix of elastic type arteries. At later stages of phylogenesis, intima was formed from media smooth muscle cells. PMID- 30289673 TI - Welcome Changes for ASSE.

AB - : The modern medical literature practically does not contain clinical publications reporting studies of factors responsible for progression of atrial fibrillation (AF) in patients with coronary heart disease (CHD). It accounts for the importance of investigations into evolution of the clinical course of AF in such patients. Aim: To elucidate evolution of the clinical course of AF in patients with CHD in a long-term prospective study. Materials and methods: The study included. 112 patient aged 57-74 (mean 67.44+/-3.3) years with CHD and paroxysmal form of AF carried outfrom 2011 to 2015. Evolution of the clinical course of AF was evaluated based on the number of arrhythmic attacks during the last 3 months. The appearance of prolonged persistent AF episodes or permanent AF was regarded as progression of arrhythmia. Results: During the 4 year study, 64 (57,2%) patients (group 1) did not experiencea rise in the frequency and duration of AF attacks. Progression of arrhythmia was documented in 48 (42,8%) of the 112 (100%) patients (group 2). These patients more frequently had the history of myocardial infarction and chronic heart failure than patients of group 1. The latter had the mean values of left ventricular (LV) ejection fraction 61,23+/ 6,24%, i.e. significantly higher than 48,47+/-8,4% in group 2.47 and 28 % of the patients in group 2and 1 respectively suffered mitral regurgitation (p<0,05). Patients of group 2 had significantly more akineticzones. Intake of nitroglycerin in group 1 resulted in positive dynamics of local LV contractility that did not change in patients of group 2. Conclusion: 42,8% of the patients with CHD and paroxysmal form of AF experienced progression of arrhythmia into a persistent or permanent form. Predictors of AF progression in patients with CHD are the history of myocardial infarction, chronic heart failure, mitral regurgitation, and irreversible changes in local myocardial LV contraction. PMID- 30289676 TI - [Polymorphisms of genesencoding enzymes of the xenobiotic detoxification system and the risk of infectious endocarditis]. AB - Infectioue endocarditis (IE) is frequently associated with the use of narcotic drugs, glucocorticosteroids, and cytostatics that are metabolized in the body by enzymes of the xenobiotic detoxification system (XDS). This work was aimed at elucidating association between IE and mononucleotide polymorphisms of genes encoding XDS enzymes. 46 IE patients and 114 subjects without cardiovascular diseases (controls) underwent genotyping for polymorphic loci of cytochrome P450 1A1 gene I462V (CYP1A1), I105VandA114V gene of glutathione-S-transferase Pi1 (GSTP1) using allele-specific PCR. The study revealed association of CYP1A1 I462VandGSTP1 I105V with IE while IE proved unrelated to GSTP1 A114V polymorphism. Combination of homozygous variant I462I of the CYP1A1 gene and heterozygous variant I105V/ of the GSTP1 gene was associated with the 9-fold increase of the risk of IE in the subjects practicing intravenous druginjections or having congenital and acquired heart failure or implanted valve prostheses. These findings suggest the necessity of further studies on the role of XDS in pathogenesis of IE and other infectious diseases.

AB - Aim: To characterize differences in the risk of development (RD) of myocardial infarction (MI) and stroke during 16 years in an open Siberian population aged 25 64 years and suffering vital exhaustion (VE). Materials and methods: We examined a random representative sample of 657 men and 870 women from the Novosibirsk population in the framework of the WHO "MONICA-psychosocial" screening III program (1954). It included registration of socio-demographic data and cases of VE. A total of 15 episodes of MI and 35 strokes were documented in 30 women and 22 men. Results: The level of VE in men was 66,8% (high in 14,6%), in women75,7% (high in 44,4%). RD of MI estimated from the relative risk (RR) in men with VE(RR=2) was higher than in women. It was higher in divorced women (RR=5,4) than in men (RR=4,7). RD of MI was higher in men with VE (OR=2,2 in subjects having elementary education, OR=3,7 in bachelors, OR = 7 in widowers;at the age from 45 to 54 years OR=3,8, at the age from 55 to 64 years OR=5,9) than in women. The overall RD of stroke in subjects of either sex with VE was not significantly different (OR=3,34 in women and 3,1). However, it was higher than in women in men with VE having partially completed secondary-level and elementary education RR=4.8), in divorced and widowed men (RR=3.8 and 3.6 respectively. Conclusion: The study showed that the prevalence of VE in the population aged 25-64yearsis higher than in other age groups and higher in women than in men. VE is a more reliable predictor of MI in men than in women; it is a predictor of stroke in either sexes. PMID- 30289680 TI - Ultraviolet-Assisted Direct Ink Write to Additively Manufacture All-Aromatic Polyimides. AB - All-aromatic polyimides have degradation temperatures above 500 degrees C, excellent mechanical strength, and chemical resistance, and are thus ideal polymers for high-temperature applications. However, their all-aromatic structure impedes additive manufacturing (AM) because of the lack of melt processability and insolubility in organic solvents. Recently, our group demonstrated the design of UV-curable polyamic acids (PAA), the precursor of polyimides, to enable their processing using vat photopolymerization AM. This work leverages our previous synthetic strategy and combines it with the high solution viscosity of nonisolated PAA to yield suitable UV-curable inks for UV-assisted direct ink write (UV-DIW). UV-DIW enabled the design of complex three-dimensional structures comprising of thin features, such as truss structures. Dynamic mechanical analysis of printed and imidized specimens confirmed the thermomechanical properties typical of all-aromatic polyimides, showing a storage modulus above 1 GPa up to 400 degrees C. Processing polyimide precursors via DIW presents opportunity for multimaterial printing of multifunctional components, such as three-dimensional integrated electronics. PMID- 30289681 TI - Fast and Scalable Hydrodynamic Synthesis of MnO2/Defect-Free Graphene Nanocomposites with High Rate Capability and Long Cycle Life. AB - The integration of metal oxides and carbon materials provides a great potential for enhancing the high energy and power densities of supercapacitors, but the rational design and scalable fabrication of such composite materials still remain a challenge. Herein, we report a fast, scalable, and one-pot hydrodynamic synthesis for preparing ion conductive and defect-free graphene from graphite and MnO2/graphene nanocomposites. The use of this hydrodynamic method using Taylor Couette flow allows us to efficiently fast shear-exfoliate graphite into large quantities of high-quality graphene sheets. Deposition of MnO2 on graphene is subsequently performed in a fluidic reactor within 10 min. The prepared MnO2/graphene nanocomposite shows outstanding electrochemical performances, such as a high specific capacitance of 679 F/g at 25 mV/s, a high rate capability of 74.7% retention at an extremely high rate of 1000 mV/s, and an excellent cycling characteristic (~94.7% retention over 20 000 cycles). An asymmetric supercapacitor device is fabricated by assembling an anode of graphene and a cathode of MnO2/graphene, which resulted in high energy (35.2 W h/kg) and power (7.4 kW/kg) densities (accounting for the mass of both electrodes and the electrolyte) with a high rate capability and long cycle life. PMID- 30289682 TI - Applications of gamma,delta-Unsaturated Ketones Synthesized by Copper-Catalyzed Cascade Addition of Vinyl Grignard Reagents to Esters. AB - gamma,delta-Unsaturated ketones, so-called homoallylic ketones, have served as versatile building blocks for the synthesis of a variety of heterocycles, carbocycles, natural products, and reactive intermediates. Procured by a variety of processes, including conjugate addition of vinyl organometallic reagents to unsaturated ketones, allylation of silyl enol ethers, and rearrangements, homoallylic ketones are often synthesized by step-intensive methods. The cascade addition of 2 equiv of vinyl Grignard reagent to a carboxylate was reported by the Lubell laboratory in 2003 to give effective access to homoallylic ketones from a variety of aromatic, aliphatic, and alpha-amino methyl esters. Employing readily accessible vinyl magnesium halides in the presence of a catalytic amount of copper salt, this cascade reaction provides high yields of homoallylic ketones with minimal side product by a process featuring the assembly and collapse of a tetrahedral intermediate with expulsion of alkoxide ion, followed by conjugate addition to the resulting enone. Application of the cascade reaction to the synthesis of various homoallylic ketones has provided versatile building blocks for the synthesis of targets for different applications. For example, by employing (hetero)aryl di- and tricarboxylates as precursors, copper-catalyzed cascade additions have provided donor-acceptor and star-shaped monomers for optical-electronic materials. Amino ester starting materials have given homoallylic ketones for the synthesis of various peptidomimetics, including heteroarylalanines, hydroxyethylene isoesters, and diazepinone turn mimics. Moreover, anthranilate has served as building block to prepare various pyrrole, quinoline, benzodiazepine, and benzotriazepine heterocyles. In addition, cascade additions on hydroxyprolinates have given access to bipyrrole precursors of the prodigiosin family of natural products. In the interest to highlight the utility of the copper-catalyzed cascade addition of vinyl Grignard reagents to carboxylates, this Account provides details on the broad scope of substrates that deliver homoallylic ketone products as well as an overview of the wide range of applications in which this method may impact including materials and peptide science, heterocycle and natural product synthesis, and medicinal chemistry. PMID- 30289683 TI - Soft-Templated Synthesis of Lightweight, Elastic, and Conductive Nanotube Aerogels. AB - Conductive polymer (CP) nanotubes are fascinating nanostructures with high electrical conductivity, fast charge/discharge capability, and high mechanical strength. Despite these attractive physical properties, progress in the synthesis of CP nanotube hydrogels is still limited. Here, we report a facile and effective approach for the synthesis of polypyrrole (PPy) nanotube hydrogels by using the weakly interconnected network of self-assembled nanotubes of lithocholic acid as a soft template. The PPy nanotube hydrogels are then converted to aerogels by freeze drying, in which PPy nanotubes form elastic and conductive networks with a density of 38 mg/cm3 and an electrical conductivity of 1.13 S/m. The PPy nanotube aerogels are able to sustain a compressive strain as high as 70% and show an excellent cyclic compressibility due to their robust nanotube networks and hierarchically porous structures, which allow the compressive stress to be easily dissipated. Furthermore, PPy nanotube aerogels show negative strain-dependent electrical resistance changes under compressive strains. The lightweight, elastic, and conductive PPy nanotube aerogels may find potential applications in strain sensors, supercapacitors, and tissue scaffolds. PMID- 30289684 TI - Real-Time Accumbal Dopamine Response to Negative Stimuli: Effects of Ethanol. AB - Activity in the mesolimbic dopamine (DA) pathway is known to have a role in reward processing and related behaviors. The mesolimbic DA response to reward has been well-examined, while the response to aversive or negative stimuli has been studied to a lesser extent and produced inconclusive results. However, a brief increase in the DA concentration in terminals during nociceptive activation has become an established but not well-characterized phenomenon. Consequently, the interpretation of the significance of this neurochemical response is still elusive. The present study was designed to further explore these increases in subsecond DA dynamics triggered by negative stimuli using voltammetry in anesthetized rats. Our experiments revealed that repeated exposure to a tail pinch resulted in more efficacious DA release in rat nucleus accumbens. This fact may suggest a protective nature of immediate DA efflux. Furthermore, a sensitized DA response to a neutral stimulus, such as a touch, was discovered following several noxious pinches, while a touch applied before these pinches did not trigger DA release. Finally, it was found that the pinch-evoked DA efflux was significantly decreased by ethanol acutely administrated at an analgesic dose. Taken together, these results support the hypothesis that subsecond DA release in the nucleus accumbens may serve as an endogenous antinociceptive signal.

AB - This Feature addresses the analysis of the reactive species generated by nonthermal atmospheric pressure plasmas, which are widely employed in industrial and biomedical research, as well as first clinical applications. We summarize the progress in detection of plasma-generated short-lived reactive oxygen and nitrogen species in aqueous solutions, discuss the potential and limitations of various analytical methods in plasma-liquid systems, and provide an outlook on the possible future research goals in development of short-lived reactive species analysis methods for a general nonspecialist audience. PMID- 30289685 TI - Preparation of Superhydrophilic Adsorbents with 3DOM Structure by Water-Soluble Colloidal Crystal Templates for Boron Removal from Natural Seawater. AB - Three-dimensionally ordered macroporous cross-linked poly(glycidyl methacrylate) (3DOM) was constructed by water-soluble colloidal crystal templates and further functionalized with N-methyl-d-glucamine (NMDG) to prepare superhydrophilic adsorbents for boron removal from natural seawater. 3DOM adsorbents possess features of interconnected macropore structure, ultrathin pore wall, and superhydrophilicity, making efficient adsorption possible. The effect of cross linking degree on the adsorption capacity toward boron was investigated. The NMDG modified 3DOM adsorbent with rich vicinal diol functional groups showed superhydrophilicity and outstanding performance of adsorption. Significantly, its adsorption effect in boron removal from natural seawater indicated that the concentration of boron in natural seawater could decline to 0.16 from 4.24 mg.L-1 when the adsorbent dosage was 1 g.L-1, whereas the boron rejection reached 96.2%. After 10 regeneration-adsorption cycles, the adsorption capacity of 3DOM adsorbent remained over 85% of the initial value and the ordered structure was hardly changed. Additionally, 3DOM adsorbent could be directly and quickly separated from the seawater by a filter mesh of 16 mesh number. Research shows that the 3DOM adsorbent exhibits an adsorption performance for practical applications in boron removal from natural seawater. PMID- 30289687 TI - Development of Mannopyranoside Therapeutics against Adherent-Invasive Escherichia coli Infections. AB - Preventing bacterial adhesion to host cells is a provocative and alternative approach to traditional antibiotic treatments given the increasing microbial resistance. A brief overview of common antibiotic treatments is described in light of their respective resistance and remaining susceptibility. This strategy has been seriously considered in the context of adherent-invasive infections in Crohn's disease and urinary tract infections in particular. The adhesions of various pathogenic Escherichia coli strains to host cells are primarily mediated through carbohydrate-protein interactions involving bacterial organelles called fimbriae that can recognize specific glycoconjugate receptors on host cells. Of particular interest are the FimH and PapG fimbriae, which bind to mannosylated glycoproteins and glycolipids of the galabiose series, respectively. Therefore, blocking FimH- and PapG-mediated bacterial adhesion to uroepithelial cells by high-affinity carbohydrate antagonists constitutes a challenging therapeutic target of high interest. This is of particular interest since bacterial adhesion to host cells is a parameter unlikely to be the subject of bacterial mutations without affecting the carbohydrate ligand binding interactions at the basis of the recognition and infection processes. To date, there have been several families of potent FimH antagonists that include natural O-linked as well as unnatural analogues of alpha-d-mannopyranosides. These observations led to a thorough understanding of the intimate binding site interactions that helped to reveal the so-called "tyrosine gate mechanism" at the origin of the strong necessary interactions with sugar-possessing hydrophobic aglycones. By modification of the aglycones of single monosaccharidic d-mannopyranosides, it was possible to replace the natural complex oligomannoside structure by simpler ones. An appealing and successful series of analogues have been disclosed, including nanomolecular architectures such as dendrimers, polymers, and liposomes. In addition, the data were compared to the above multivalent architectures and confirmed the possibility of working with small sugar candidates. This Account primarily concentrates on the most promising types of FimH inhibitors belonging to the family of alpha-C-linked mannopyranosides. However, one of the drawbacks associated with C-mannopyranosides has been that they were believed to be in the inverted chair conformation, which is obviously not recognized by the E. coli FimH. To decipher this situation, various synthetic approaches, conformational aspects, and restrictions are discussed using molecular modeling, high-field NMR spectroscopy, and X-ray analysis. These combined techniques pointed to the fact that several alpha-C-linked mannopyranosides do exist in the required 4C1 chair conformation. Ultimately, recent findings in this growing field of interest culminated in the identification of drug candidates that have reached clinical phase I. PMID- 30289689 TI - Fluorescent Benzothiazinone Analogues Efficiently and Selectively Label Dpre1 in Mycobacteria and Actinobacteria. AB - Benzothiazinones (BTZ) are highly potent bactericidal inhibitors of mycobacteria and the lead compound, BTZ043, and the optimized drug candidate, PBTZ169, have potential for the treatment of tuberculosis. Here, we exploited the tractability of the BTZ scaffold by attaching a range of fluorophores to the 2-substituent of the BTZ ring via short linkers. We show by means of fluorescence imaging that the most advanced derivative, JN108, is capable of efficiently labeling its target, the essential flavoenzyme DprE1, both in cell-free extracts and after purification as well as in growing cells of different actinobacterial species. DprE1 displays a polar localization in Mycobacterium tuberculosis, M. marinum, M. smegmatis, and Nocardia farcinica but not in Corynebacterium glutamicum. Finally, mutation of the cysteine residue in DprE1 in these species, to which BTZ covalently binds, abolishes completely the interaction with JN108, thereby highlighting the specificity of this fluorescent probe. PMID- 30289690 TI - Stretching and Breaking of Ultrathin 2D Hybrid Organic-Inorganic Perovskites. AB - Two-dimensional (2D) hybrid organic-inorganic perovskites (HOIPs) are recent members of the 2D materials family with wide tunability, highly dynamic structural features, and excellent physical properties. Ultrathin 2D HOIPs and their heterostructures with other 2D materials have been exploited for study of physical phenomena and device applications. The in-plane mechanical properties of 2D ultrathin HOIPs are critical for understanding the coupling between mechanical and other physical fields and for integrated devices applications. Here we report the in-plane mechanical properties of ultrathin freestanding 2D lead iodide perovskite membranes and their dependence on the membrane thickness. The in-plane Young's moduli of 2D HOIPs are smaller than that of conventional covalently bonded 2D materials. As the thickness increases from monolayer to three-layer, both the Young's modulus and breaking strength decrease, while three-layer and four-layer 2D HOIPs have almost identical in-plane mechanical properties. These thickness-dependent mechanical properties can be attributed to interlayer slippage during deformation. Our results show that ultrathin 2D HOIPs exhibit outstanding breaking strength/Young's modulus ratio compared to many other widely used engineering materials and polymeric flexible substrates, which renders them suitable for application into flexible electronic devices. PMID- 30289688 TI - Ligand Density and Nanoparticle Clustering Cooperate in the Multivalent Amplification of Epidermal Growth Factor Receptor Activation. AB - Multivalent presentation of ligands on nanoparticles (NPs) is considered a general strategy for enhancing receptor binding and activation through amplification of ligand-receptor interactions within the footprint of the individual NPs. The spatial clustering of ligand-functionalized NPs represents an additional, less well understood mechanism for increasing local ligand-receptor interactions, especially for receptors that form higher-order assemblies, such as the epidermal growth factor (EGF) receptor (EGFR). To shed light on the interplay between ligand density ( i.e., multivalency) and NP clustering in signal amplification, we apply EGF-functionalized 72 +/- 1 nm gold nanoparticles (NP EGF) with known ligand loading (10-200 EGF/NP) as quantifiable and experimentally tractable units of EGFR activation and characterize the NP-mediated amplification of EGFR phosphorylation as a function of both EGF surface density and NP-EGF clustering for two cancer cell lines (HeLa and MDA-MB-468). The measurements confirm a strong multivalent amplification of EGFR phosphorylation through NP-EGF on the cellular level that results in EGF-loading-dependent maximum EGFR phosphorylation levels. A microscopic analysis of NP-EGF-induced EGFR phosphorylation reveals a heterogeneous spatial distribution of EGFR activation across the cell surface. Clustering of multivalent NP-EGF on sub-diffraction limited length scales is found to result in a local enhancement of EGFR phosphorylation in signaling "hot spots" from where the signal can spread laterally in an EGF-independent fashion. Increasing EGF loadings of the NP enhances NP-EGF clustering and intensifies EGFR phosphorylation. These observations suggest that NP-EGF clustering and the associated local enhancement of ligand-receptor interactions are intrinsic components of the multivalent amplification of phosphorylation for the heterogeneously distributed EGFR through NP-EGF.

AB - Substituted 1,3-dienes are valuable synthetic intermediates used in myriad catalytic transformations, yet modern catalytic methods for their preparation in a highly modular fashion using simple precursors are relatively few. We report here an aerobic boron Heck reaction with cyclobutene that forms exclusively linear 1-aryl-1,3-dienes using (hetero)arylboronic acids, or 1,3,5-trienes using alkenylboronic acids, rather than typical Heck products (i.e., substituted cyclobutenes). Experimental and computational mechanistic data support a pericyclic mechanism for C-C bond cleavage that enables the cycloalkene to circumvent established limitations associated with diene reagents in Heck-type reactions. PMID- 30289692 TI - Discovery and Characterization of a Thioesterase-Specific Monoclonal Antibody That Recognizes the 6-Deoxyerythronolide B Synthase. AB - Assembly line polyketide synthases (PKSs) are large multimodular enzymes responsible for the biosynthesis of diverse antibiotics in bacteria. Structural and mechanistic analysis of these megasynthases can benefit from the discovery of reagents that recognize individual domains or linkers in a site-specific manner. Monoclonal antibodies not only have proven themselves as premier tools in analogous applications but also have the added benefit of constraining the conformational flexibility of their targets in unpredictable but often useful ways. Here we have exploited a library based on the naive human antibody repertoire to discover a Fab (3A6) that recognizes the terminal thioesterase (TE) domain of the 6-deoxyerythronolide B synthase with high specificity. Biochemical assays were used to verify that 3A6 binding does not inhibit enzyme turnover. The co-crystal structure of the TE-3A6 complex was determined at 2.45 A resolution, resulting in atomic characterization of this protein-protein recognition mechanism. Fab binding had minimal effects on the structural integrity of the TE. In turn, these insights were used to interrogate via small-angle X-ray scattering the solution-phase conformation of 3A6 complexed to a catalytically competent PKS module and bimodule. Altogether, we have developed a high-affinity monoclonal antibody tool that recognizes the TE domain of the 6-deoxyerythronolide B synthase while maintaining its native function. PMID- 30289693 TI - Rare-Earth-Doped Ceria Systems and Their Performance as Solid Electrolytes: A Puzzling Tangle of Structural Issues at the Average and Local Scale. AB - Rare-earth (RE)-doped ceria systems, in particular when RE = Nd, Sm, or Gd, are well-known to be characterized by high values of ionic conductivity in the intermediate temperature range, which, in principle, makes them ideal solid electrolytes in solid oxide fuel and electrolysis cells. Defect chemistry turns out to be a pivotal issue in this framework because ionic conductivity is driven by the ability of oxygen vacancies to move through the lattice, and any form of defect clustering tends to depress the efficiency of oxygen transport. In this viewpoint, not only are factors at the average scale assessed, such as the compositional extent of the CeO2-like solid solution, but also the occurrence of local inhomogeneities due to vacancy-dopant association is discussed in correlation with its central role in hindering the migration of vacancies. The relationship between the stability of the hybrid phase and the RE3+ ionic size is presented, and the highly complementary role of Raman spectroscopy toward X-ray diffraction is described in detail. The key points of the whole discussion are finally used to identify the most relevant structure-related parameters affecting ionic conductivity in the studied material. PMID- 30289694 TI - Small Structural Variations Have Large Effects on the Assembly Properties and Spin State of Room Temperature High Spin Fe(II) Iminopyridine Cages. AB - Small changes in steric bulk at the terminus of bis-iminopyridine ligands can effect large changes in the spin state of self-assembled Fe(II)-iminopyridine cage complexes. If the added bulk is properly matched with ligands that are either sufficiently flexible to allow twisted octahedral geometries at the Fe centers or can assemble with unusual mer configurations at the metals, room temperature high spin Fe(II) cages can be synthesized. These complexes maintain their high spin state in solution at low temperatures and have been characterized by X-ray crystallographic and computational methods. The high spin M2L3 meso helicate and M4L6 cage complexes display longer N-Fe bond distances and larger interligand N-Fe-N bond angles than their diamagnetic counterparts, and these structural changes invert the ligand selectivity in narcissistic self-sorting and accelerate subcomponent exchange rates. The paramagnetic cages can be easily converted to diamagnetic cages by subcomponent exchange under mild conditions, and the intermediates of the exchange process can be visualized in situ by NMR analysis. PMID- 30289695 TI - Nanofibers with Incorporated Autochthonous Bacteria as Potential Probiotics for Local Treatment of Periodontal Disease. AB - The conventional treatment of periodontal disease does not solve the high incidence of recolonization of periodontal pockets by pathogens. Here, we introduce an innovative concept of incorporating autochthonous bacteria as potential probiotics into nanofibers for local treatment. We selected and isolated the strain 25.2.M from the oral microbiota of healthy volunteers. It was identified as Bacillus sp. based on 16S rRNA sequence analyses. The strain is nonpathogenic, produces antimicrobial substances, and can grow over the periodontal pathogen Aggregatibacter actinomycetemcomitans in vitro, making it a promising probiotic candidate. The strain 25.2.M was successfully incorporated into the nanofibers in the form of spores (107 CFU/mg), the viabilities of which were exceptional (max. change of 1 log unit) both during electrospinning and after 12 months of storage. The release of the bacteria was delayed from chitosan/poly(ethylene oxide) compared to poly(ethylene oxide) nanofibers, and the antimicrobial activity against A. actinomycetemcomitans was confirmed. The developed nanodelivery system for administration into periodontal pockets thus offers a promising approach for the inhibition of periodontal pathogens and restoration of healthy oral microbiota.

These complexes disproportionate at pH <= 6, but are stable in anaerobic water at pH 7 10 for several days. PMID- 30289697 TI - Antiparallel Coiled-Coil Interactions Mediate the Homodimerization of the DNA Damage-Repair Protein PALB2. AB - Deficits in DNA damage-repair pathways are the root cause of several human cancers. In mammalian cells, DNA double-strand break repair is carried out by multiple mechanisms, including homologous recombination (HR). The partner and localizer of BRCA2 (PALB2), which is an essential factor for HR, binds to the breast cancer susceptibility 1 (BRCA1) protein at DNA double-strand breaks. At the break site, PALB2 also associates with the breast cancer susceptibility 2 (BRCA2) protein to form a multiprotein complex that facilitates HR. The BRCA1 PALB2 interaction is mediated by association of predicted helical coiled-coil regions in both proteins. PALB2 can also homodimerize through the formation of a coiled coil by the self-association of helical elements at the N-terminus of the PALB2 protein, and this homodimerization has been proposed to regulate the efficiency of HR. We have produced a segment of PALB2, designated PALB2cc (PALB2 coiled coil segment) that forms alpha-helical structures, which assemble into stable homodimers. PALB2cc also forms heterodimers with a helical segment of BRCA1, called BRCA1cc (BRCA1 coiled coil segment). The three-dimensional structure of the homodimer formed by PALB2cc was determined by solution NMR spectroscopy. This PALB2cc homodimer is a classical antiparallel coiled-coil leucine zipper. NMR chemical-shift perturbation studies were used to study dimer formation for both the PALB2cc homodimer and the PALB2cc/BRCA1cc heterodimer. The mutation of residue Leu24 of PALB2cc significantly reduces its homodimer stability, but has a more modest effect on the stability of the heterodimer formed between PALB2cc and BRCA1cc. We show that mutation of Leu24 leads to genomic instability and reduced cell viability after treatment with agents that induce DNA double-strand breaks. These studies may allow the identification of distinct mutations of PALB2cc that selectively disrupt homodimeric versus heterodimeric interactions, and reveal the specific role of PALB2cc homodimerization in HR.

AB - This paper quantifies and compares the life cycle GHG emissions and costs of production of diesel and jet fuel derived from municipal solid waste (MSW) in the United States via three thermochemical conversion pathways: conventional gasification and Fischer-Tropsch (FT middle distillate, MD), plasma gasification and Fischer-Tropsch (Plasma FT MD), and conventional gasification, catalytic alcohol synthesis, and alcohol-to-jet upgrading (ATJ MD). We use expanded system boundaries to capture the change in existing MSW use and disposal, and account for parameter uncertainty with Monte Carlo simulations. We estimate median life cycle GHG emissions of 32.9, 62.3, and 52.7 gCO2e/MJ for FT, Plasma FT and ATJ MD fuels, respectively, compared to a baseline of 90 gCO2e/MJ for conventional MD fuels. Median minimum selling prices are estimated at 0.99, 1.78, and 1.20 $ per liter with the probability of achieving a positive net present value of fuel production at market prices of 14%, 0.1% and 7% for FT, Plasma FT and ATJ MD fuels, respectively. If the societal perspective rather than an investor's perspective is evaluated, then the probability of positive net present value of fuel production increases to 93%, 67%, and 92.5% for the FT, Plasma FT, and ATJ MD fuels, respectively.

AB - [4]Chrysaorene, a fully conjugated carbocyclic coronoid, is shown to be a low bandgap pi-conjugated system with a distinct open-shell character. The system shows good chemical stability and can be oxidized to well-defined radical cation and dication states. The cavity of [4]chrysaorene acts as an anion receptor toward halide ions with a particular selectivity toward iodides ( Ka = 207 +/- 6 M-1). The interplay between anion binding and redox chemistry is demonstrated using a 1H NMR analysis in solution. In particular, a well-resolved, paramagnetically shifted spectrum of the [4]chrysaorene radical cation is observed, providing evidence for the inner binding of the iodide. The radical cation-iodide adduct can be generated in thin solid films of [4] chrysaorene by simple exposure to diiodine vapor. PMID- 30289700 TI - Identification and Quantitative Analysis of 2-Methyl-4-propyl-1,3-oxathiane in Wine. AB - On the basis of the chemistry of wine and the co-occurrence of 3-sulfanylhexan-1 ol (3-SH) and acetaldehyde, we investigated the existence of 2-methyl-4-propyl 1,3-oxathiane (1) and identified the presence of a single detectable geometric isomer, cis-1, in wines for the first time. A stable isotope dilution assay (SIDA) using headspace-solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS) was developed and validated, and used to quantitate cis-1 in a survey of wines, revealing a range from undetectable (limit of detection = 2.6 ng/L) to 460 ng/L. The odor detection threshold of 1 (using a standard comprising 85% cis-1 and 15% trans-1) in neutral white wine was determined to be 7.1 MUg/L. Despite cis-1 not appearing above the determined sensory threshold in the studied wines, the findings demonstrated the presence of a new volatile sulfur compound with a strong correlation to 3-SH concentration ( r = 0.72), showing that cis-1 has potential implications for the fate of the important wine aroma compound 3-SH. PMID- 30289701 TI - Controlling the Morphology of Au-Pd Heterodimer Nanoparticles by Surface Ligands. AB - Controlling the morphology of noble-metal nanoparticles is mandatory to tune specific properties such as catalytic and optical behavior. Heterodimers consisting of two noble metals have been synthesized, so far mostly in aqueous media using selective surfactants or chemical etching strategies. We report a facile synthesis for Au@Pd and Pd@Au heterodimer nanoparticles (NPs) with morphologies ranging from segregated domains (heteroparticles) to core-shell structures by applying a seed-mediated growth process with Au and Pd seed nanoparticles in 1-octadecene (ODE), which is a high-boiling organic solvent. The as-synthesized oleylamine (OAm) functionalized Au NPs led to the formation of OAm Au@Pd heteroparticles with a "windmill" morphology, having an Au core and Pd "blades". The multiply twinned structure of the Au seed particles (? ~ 9-11 nm) is associated with a reduced barrier for heterogeneous nucleation. This leads to island growth of bimetallic Au@Pd heteroparticles with less-regular morphologies. The reaction process can be controlled by tuning the surface chemistry with organic ligands. Functionalization of Au NPs (O ~ 9-11 nm) with 1-octadecanethiol (ODT) led to the formation of ODT-Au@Pd NPs with a closed Pd shell through a strong ligand-metal binding, which is accompanied by a redistribution of the electron density. Experiments with varied Pd content revealed surface epitaxial growth of Pd on Au. For OAm-Pd and ODT-Pd seed particles, faceted, Au-rich domain NPs and impeded core-shell NPs were obtained, respectively. This is related to the high surface energy of the small Pd seed particles (? ~ 5-7 nm). The metal distribution of all bimetallic NPs was analyzed by extended (aberration corrected) transmission electron microscopy (HR-TEM, HAADF-STEM, EDX mapping, ED). The Au and Pd NPs, as well as the ODT-Au@Pd and OAm-Pd@Au heteroparticles, catalyze the reduction of 4-nitrophenol to 4-aminophenol with borohydride. The catalytic activity is dictated by the particle structure. OAm-Au@Pd heteroparticles with faceted Au domains had the highest activity because of a mixed Au-Pd surface structure, while ODT-Au@Pd NPs, where the active Au core is covered by a Pd shell, had the lowest activity. PMID- 30289703 TI - Evolutionarily Conserved Allosteric Communication in Protein Tyrosine Phosphatases. AB - Protein tyrosine phosphatases (PTPs) are an important class of regulatory enzymes that exhibit aberrant activities in a wide range of diseases. A detailed mapping of allosteric communication in these enzymes could, thus, reveal the structural basis of physiologically relevant-and, perhaps, therapeutically informative perturbations (i.e., mutations, post-translational modifications, or binding events) that influence their catalytic states. This study combines detailed biophysical studies of protein tyrosine phosphatase 1B (PTP1B) with bioinformatic analyses of the PTP family to examine allosteric communication in this class of enzymes. Results of X-ray crystallography, molecular dynamics simulations, and sequence-based statistical analyses indicate that PTP1B possesses a broadly distributed allosteric network that is evolutionarily conserved across the PTP family, and findings from both kinetic studies and mutational analyses show that this network is functionally intact in sequence-diverse PTPs. The allosteric network resolved in this study reveals new sites for targeting allosteric inhibitors of PTPs and helps explain the functional influence of a diverse set of disease-associated mutations. PMID- 30289702 TI - Self-Assembly of Supramolecular Fractals from Generation 1 to 5. AB - In the seeking of molecular expression of fractal geometry, chemists have endeavored in the construction of molecules and supramolecules during the past few years, while only a few examples were reported, especially for the discrete architectures. We herein designed and constructed five generations of supramolecular fractals (G1-G5) based on the coordination-driven self-assembly of terpyridine ligands. All the ligands were synthesized from triphenylamine motif, which played a central role in geometry control. Different approaches based on direct Sonogashira coupling and/or ?tpy-Ru(II)-tpy? connectivity were employed to prepare complex Ru(II)-organic building blocks. Fractals G1-G5 were obtained in high yields by precise coordination of organic or Ru(II)-organic building blocks with Zn(II) ions. Characterization of those architectures were accomplished by 1D and 2D NMR spectroscopy, electrospray ionization mass spectrometry (ESI-MS), traveling-wave ion mobility mass spectrometry (TWIM-MS), and transmission electron microscopy (TEM). Furthermore, the two largest fractals also hierarchically self-assemble into ordered supramolecular nanostructures either at solid/liquid interface or in solution on the basis of their well-defined scaffolds. PMID- 30289704 TI - Best of Two Worlds? How MD Simulations of Amphiphilic Helical Peptides in Membranes Can Complement Data from Oriented Solid-State NMR. AB - The membrane alignment of helical amphiphilic peptides in oriented phospholipid bilayers can be obtained as ensemble and time averages from solid state 2H NMR by fitting the quadrupolar splittings to ideal alpha-helices. At the same time, molecular dynamics (MD) simulations can provide atomistic insight into peptide membrane systems. Here, we evaluate the potential of MD simulations to complement the experimental NMR data that is available on three exemplary systems: the natural antimicrobial peptide PGLa and the two designer-made peptides MSI-103 and KIA14, whose sequences were derived from PGLa. Each peptide was simulated for 1 MUs in a DMPC lipid bilayer. We calculated from the MD simulations the local angles which define the side chain geometry with respect to the peptide helix. The peptide orientation was then calculated (i) directly from the simulation, (ii) from back-calculated MD-derived NMR splittings, and (iii) from experimental 2H NMR splittings. Our findings are that (1) the membrane orientation and secondary structure of the peptides found in the NMR analysis are generally well reproduced by the simulations; (2) the geometry of the side chains with respect to the helix backbone can deviate significantly from the ideal structure depending on the specific residue, but on average all side chains have the same orientation; and (3) for all of our peptides, the azimuthal rotation angle found from the MD-derived splittings is about 15 degrees smaller than the experimental value. PMID- 30289705 TI - Smart Polymersomes Dually Functionalized with cRGD and Fusogenic GALA Peptides Enable Specific and High-Efficiency Cytosolic Delivery of Apoptotic Proteins. AB - Low cell selectivity and uptake coupled with endosomal entrapment pose critical hurdles for intracellular delivery and clinical translation of therapeutic proteins. Herein, we report that smart polymersomes dually functionalized with cRGD and fusogenic GALA peptides (cRGD/GALA-Ps) enable alphanubeta3-specific and high-efficiency cytosolic delivery of cytochrome C (CC), a model apoptotic protein, to A549 human lung cancer cells. cRGD/GALA-Ps was prepared with 20 mol % cRGD and varying GALA contents from 2 to 4 to 6 mol % via coassembly of PEG- b poly(trimethylene carbonate- co-dithiolane trimethylene carbonate)-spermine (PEG- b-P(TMC- co-DTC)-spermine), cRGD-PEG- b-P(TMC- co-DTC), and maleimide-PEG- b P(TMC- co-DTC) and postmodification using GALA-SH (sequence: CWEAALAEALAEALAEHLAEALAEALEALAA). cRGD/GALA-Ps loaded with ~13 wt % CC displayed a small size of about 65 nm and fast glutathione-triggered protein release. Interestingly, cRGD/GALA-Ps maintained a similar targeting ability to cRGD-Ps in alphanubeta3-positive A549 lung cancer cells, while markedly enhanced cytosolic release of FITC-labeled CC, as revealed by confocal microscopy. MTT assays exhibited that CC-loaded cRGD/GALA-Ps was significantly more potent than CC loaded cRGD-Ps, in which cell viabilities of 76.2, 51.0, 29.6, and 35.5% were discerned for cRGD/GALA-Ps with 0, 2, 4, and 6 mol % GALA, respectively, at 15.4 MUM CC. Apoptosis assays corroborated that cRGD/GALA-Ps-CC with 4 mol % GALA induced better apoptosis of A549 cells than cRGD-Ps-CC (cell apoptosis: 36.4 vs 14.4%). These results highlight that dual-functionalization of polymersomes with targeting and fusogenic peptides provides an appealing strategy for cytosolic protein delivery. PMID- 30289706 TI - Lipid- and Cholesterol-Mediated Time-Scale-Specific Modulation of the Outer Membrane Protein X Dynamics in Lipid Bilayers. AB - Membrane protein function fundamentally depends on lipid-bilayer fluidity and the composition of the biological membrane. Although dynamic interdependencies between membrane proteins and the surrounding lipids are suspected, a detailed description is still missing. To uncover lipid-modulated membrane protein backbone dynamics, time-scale-specific NMR relaxation experiments with residue resolution were recorded. The data revealed that lipid order, modified either biochemically or biophysically, changes the dynamics of the immersed membrane protein in a specific and time-scale-dependent manner. A temperature-dependent dynamics analysis furthermore suggests a direct coupling between lipid and protein dynamics in the picosecond-nanosecond, microsecond, and millisecond time scales, caused by the lipid's trans-gauche isomerization, the segmental and rotational motion of lipids, and the fluidity of the lipid phase, respectively. These observations provide evidence of a direct modulatory capability of the membrane to regulate protein function through lipid dynamics ranging from picoseconds to milliseconds. PMID- 30289707 TI - Structural Approach To Identify a Lead Scaffold That Targets the Translesion Synthesis Polymerase Rev1. AB - Translesion synthesis (TLS) is a mechanism of replication past damaged DNA through which multiple forms of human cancer survive and acquire resistance to first-line genotoxic chemotherapies. As such, TLS is emerging as a promising target for the development of a new class of anticancer agents. The C-terminal domain of the DNA polymerase Rev1 (Rev1-CT) mediates assembly of the functional TLS complex through protein-protein interactions (PPIs) with Rev1 interacting regions (RIRs) of several other TLS DNA polymerases. Utilizing structural knowledge of the Rev1-CT/RIR interface, we have identified the phenazopyridine scaffold as an inhibitor of this essential TLS PPI. We demonstrate direct binding of this scaffold to Rev1-CT, and the synthesis and evaluation of a small series of analogues have provided important structure-activity relationships for further development of this scaffold. Furthermore, we utilized the umbrella sampling method to predict the free energy of binding to Rev1-CT for each of our analogues. Binding energies calculated through umbrella sampling correlated well with experimentally determined IC50 values, validating this computational tool as a viable approach to predict the biological activity for inhibitors of the Rev1 CT/RIR PPI. PMID- 30289708 TI - Crystalline 2D Covalent Organic Framework Membranes for High-Flux Organic Solvent Nanofiltration. AB - Two-dimensional (2D) covalent organic framework (COF) materials have the most suitable microstructure for membrane applications in order to achieve both high flux and high selectivity. Here, we report the synthesis of a crystalline TFP-DHF 2D COF membrane constructed from two precursors of 1,3,5-triformylphloroglucinol (TFP) and 9,9-dihexylfluorene-2,7-diamine (DHF) through the Langmuir-Blodgett (LB) method, for the first timed. A single COF layer is precisely four unit cells thick and can be transferred to different support surfaces layer by layer. The TFP-DHF 2D COF membrane supported on an anodic aluminum oxide (AAO) porous support displayed remarkable permeabilities for both polar and nonpolar organic solvents, which were approximately 100 times higher than that of the amorphous membranes prepared by the same procedure and similar to that for the best of the reported polymer membranes. The transport mechanism through the TFP-DHF 2D COF membrane was found to be a viscous flow coupled with a strong slip boundary enhancement, which was also different from those of the amorphous polymer membranes. The membrane exhibited a steep molecular sieving with a molecular weight retention onset (MWRO) of approximately 600 Da and a molecular weight cutoff (MWCO) of approximately 900 Da. The substantial performance enhancement was attributed to the structural change from an amorphous structure to a well defined ordered porous structure, which clearly demonstrated the high potential for the application of 2D COFs as the next generation of membrane materials.

AB - Herein, we reported a successful Suzuki-Miyaura coupling of dimethyl aryl amines to forge biaryl skeleton via Ni catalysis in the absence of directing groups and preactivation. This transformation proceeded with high efficiency in the presence of magnesium. Preliminary mechanism studies demonstrated dual roles of magnesium: (i) a reductant that reduced Ni(II) species to active Ni(I) catalyst; (ii) a unique promoter that facilitated the Ni(I)/Ni(III) catalytic cycle.

AB - Food fraud can be highly lucrative, and high accuracy authentication of various foodstuffs is becoming essential. Olive oil is one of the most investigated food matrices, due to its high price and low production globally, with recent food fraud examples showing little or no high quality olive oil in the tested oils. Here a simple method using a 405 nm LED flashlight and a smartphone is developed for edible oil authentication. Identification is fingerprinted by intrinsic fluorescent compounds in the oils, such as chlorophylls and polyphenols. This study uses the hue parameter of HSV-colorspace to authenticate 24 different edible oils of 9 different types and 15 different brands. For extra virgin olive oil, all nine samples are well separated from the other oil samples. The rest of the samples were also well type-distinguished by the hue parameter, which is complemented by hue-histogram analysis. This opens up opportunities for low-cost and high-throughput smartphone field-testing of edible oils on all levels of the production and supply chain. PMID- 30289710 TI - Automated Topology Builder Version 3.0: Prediction of Solvation Free Enthalpies in Water and Hexane. AB - The ability of atomic interaction parameters generated using the Automated Topology Builder and Repository version 3.0 (ATB3.0) to predict experimental hydration free enthalpies (Delta Gwater) and solvation free enthalpies in the apolar solvent hexane (Delta Ghexane) is presented. For a validation set of 685 molecules the average unsigned error (AUE) between Delta Gwater values calculated using the ATB3.0 and experiment is 3.8 kJ.mol-1. The slope of the line of best fit is 1.00, the intercept -1.0 kJ.mol-1, and the R2 0.90. For the more restricted set of 239 molecules used to validate OPLS3 ( J. Chem. Theory Comput. 2016 , 12 , 281 - 296 , DOI: 10.1021/acs.jctc.5b00864 ) the AUE using the ATB3.0 is just 2.7 kJ.mol-1 and the R2 0.93. A roadmap for further improvement of the ATB parameters is presented together with a discussion of the challenges of validating force fields against the available experimental data. PMID- 30289712 TI - Reproducibility of Free Energy Calculations across Different Molecular Simulation Software Packages. AB - Alchemical free energy calculations are an increasingly important modern simulation technique to calculate free energy changes on binding or solvation. Contemporary molecular simulation software such as AMBER, CHARMM, GROMACS, and SOMD include support for the method. Implementation details vary among those codes, but users expect reliability and reproducibility, i.e., for a given molecular model and set of force field parameters, comparable free energy differences should be obtained within statistical bounds regardless of the code used. Relative alchemical free energy (RAFE) simulation is increasingly used to support molecule discovery projects, yet the reproducibility of the methodology has been less well tested than its absolute counterpart. Here we present RAFE calculations of hydration free energies for a set of small organic molecules and demonstrate that free energies can be reproduced to within about 0.2 kcal/mol with the aforementioned codes. Absolute alchemical free energy simulations have been carried out as a reference. Achieving this level of reproducibility requires considerable attention to detail and package-specific simulation protocols, and no universally applicable protocol emerges. The benchmarks and protocols reported here should be useful for the community to validate new and future versions of software for free energy calculations. PMID- 30289713 TI - Structurally Diverse Sesquiterpenoids from the Endangered Ornamental Plant Michelia shiluensis. AB - A preliminary phytochemical investigation on the MeOH extract of the leaves and twigs of the endangered ornamental plant Michelia shiluensis led to the isolation of 16 sesquiterpenoids. The isolated compounds comprised germacrane- (1-4, 13, 14), guaiane- (5-9, 15), amorphane- (10), and eudesmane-type (11, 12, 16) sesquiterpenoids. The new structures (1-12) were elucidated by spectroscopic and computational methods, and their absolute configurations (except for 9) were assigned by single-crystal X-ray diffraction crystallographic data and/or electronic circular dichroism spectra. Shiluolides (A-D, 1-4) are unprecedented C16 or C17 homogermacranolides, and their putative biosynthetic pathways are briefly discussed. Shiluone D (8) is a rare 1,10- seco-guaiane sesquiterpenoid featuring a new ether-containing spirocyclic ring, whereas shiluone E (9) represents the first example of a 1,5-4,5-di- seco-guaiane with a rare 5,11 lactone moiety. Shiluone F (10) is the first amorphane-type sesquiterpenoid possessing an oxetane ring bridging C-1 and C-7. Bioassay evaluations indicated that lipiferolide (13) showed noteworthy cytotoxicities toward human cancer cell lines MCF-7 and A-549, with IC50 values of 1.5 and 7.3 MUM, respectively. Shiluone D (8) exerted inhibition against protein tyrosine phosphatase 1B (IC50: 46.3 MUM). PMID- 30289714 TI - Prevention and Disintegration of Human Serum Albumin Fibrils under Physiological Conditions: Biophysical Aspects. AB - An anomaly in the protein folding process can lead to aggregation or fibrillation of proteins which has been related to neurodegenerative and peripheral diseases. Therefore, it is important to understand the mechanism of prevention of aggregation/fibrillation and to design suitable inhibitors for this process. Literature information suggests that most of the work on these systems has been done on heat induced fibrils (57-65 degrees C). As a step ahead, in the present study, efforts have been made to understand the inhibition process under physiological conditions (37 degrees C, pH 7.4), which is more relevant to the fibrils formed under natural cellular environment. The qualitative and quantitative aspects of the interactions of the surfactant sodium dodecyl sulphate (SDS) and antiinflammatory drug diclofenac sodium (DCF) with human serum albumin at different stages of the fibrillation process have been studied employing a combination of spectroscopic, calorimetric, and microscopic techniques. Fibril formation understudied conditions was confirmed by transmission electron microscopy images and thioflavin T binding assay along with dynamic light scattering measurements. Energetics from isothermal titration calorimetry provided insights into the nature of interactions and the mechanism of inhibition. We found inhibition efficiency of the additives in the order, micellar SDS > 45 mM DCF > monomeric SDS > 5 mM DCF. The energetics of interaction, correlated with the molecular structure of inhibitors provides guidelines for effective synthesis and design of inhibitors. ITC results have imparted important relationship between inhibition efficiency and exothermicity of interactions and have demonstrated the significance of polar interactions in fibril prevention by these inhibitors. Interestingly it was found that the micellar SDS not only inhibits the process but also effectively disintegrates the formed fibrils. PMID- 30289715 TI - ASV-ID, a Proteogenomic Workflow to Predict Candidate Protein Isoforms based on Transcript Evidence. AB - One of the goals of the Chromosome-centric Human Proteome Project (C-HPP) is to map and characterize the functions of protein isoforms produced by alternative splicing of genes. However, identifying alternative splice variants (ASVs) via mass spectrometry remains a major challenge, because ASVs usually contain highly homologous peptide sequences. A routine protein sequence analysis suggests that more than half of the investigated proteins do not generate two or more uniquely mapping peptides that would enable their isoforms to be distinguished. Here, we develop a new proteogenomics method, named "ASV-ID" (alternative splicing variants identification), which enables identification of ASVs by using a cell type-specific protein sequence database that is supported by RNA-Seq data. Using this workflow, we identify 1,935 distinct proteins under highly stringent conditions. In fact, transcript evidence on these 841 proteins helps us distinguish them from other isoforms, despite the fact that these proteins are not predicted to make 2 or more uniquely mapping peptides. We also demonstrate that ASV-ID enables detection of 19 differently expressed isoforms present in several cell lines. Thus, a new workflow using ASV-ID has the potential to map yet-to-be-identified difficult protein isoforms in a simple and robust way.

AB - HIF-2alpha, a member of the HIF family of transcription factors, is a key oncogenic driver in cancers such as clear cell renal cell carcinoma (ccRCC). A signature feature of these cancers is the overaccumulation of HIF-2alpha protein, often by inactivation of the E3 ligase VHL (von Hippel-Lindau). Herein we disclose our structure based drug design (SBDD) approach that culminated in the identification of PT2385, the first HIF-2alpha antagonist to enter clinical trials. Highlights include the use of a putative n -> pi*Ar interaction to guide early analog design, the conformational restriction of an essential hydroxyl moiety, and the remarkable impact of fluorination near the hydroxyl group. Evaluation of select compounds from two structural classes in a sequence of PK/PD, efficacy, PK, and metabolite profiling identified 10i (PT2385, luciferase EC50 = 27 nM) as the clinical candidate. Finally, a retrospective crystallographic analysis describes the structural perturbations necessary for efficient antagonism. PMID- 30289717 TI - Long-Lasting Complex Reaction Behavior in a Closed Ferroin-Bromate Hydroxybenzenesulfonate System. AB - The bromate-phenolsulfonate reaction was found to exhibit spontaneous oscillations in a batch reactor, where the addition of small amounts of ferroin would result in nonoscillatory behavior. As the ferroin concentration was increased, the system produced very rich nonlinear behavior, including three isolated oscillatory regimes that were separated by as long as 48 h nonoscillatory period. The long-lasting nonlinear behavior may be attributed to the slow desulfonation of phenolsulfonate in an acidic solution, forming phenol like intermediates. However, unlike the bromate-phenol oscillator, oxygen was found to greatly influence the reaction, and various complex oscillations could be observed by tuning the oxygen concentration. Mechanistic studies performed through employing 1H NMR spectroscopy and mass spectrometry to measure intermediate species at different stages of the reaction were able to identify 1,4-benzoquinone, 2-bromo-1,4-benzoquinone, 2,6-dibromo-1,4-benzoquinone, and 2,4,6-tribromophenol as major components during the reaction. PMID- 30289718 TI - Relevance of the Resonance Junctions on the Arnold Web to Dynamical Tunneling and Eigenstate Delocalization. AB - We study the competition and correspondence between the classical and quantum routes to intramolecular vibrational energy redistribution (IVR) in a three degrees of freedom model effective Hamiltonian. Specifically, we focus on the classical and the quantum dynamics near the resonance junctions on the Arnold web that are formed by an intersection of independent resonances. The regime of interest models the IVR dynamics from highly excited initial states near dissociation thresholds of molecular systems wherein both classical and purely quantum, involving dynamical tunneling, routes to IVR coexist. In the vicinity of a resonance junction, classical chaos is inevitably present, and hence one expects the quantum IVR pathways to have a strong classical component as well. We show that with increasing resonant coupling strengths the classical component of IVR leads to a transition from coherent dynamical tunneling to incoherent dynamical tunneling. Furthermore, we establish that the quantum IVR dynamics can be predicted based on the structures on the classical Arnold web. In addition, we investigate the nature of the highly excited eigenstates to identify the quantum signatures of the multiplicity-2 junctions. For the parameter regimes studies herein, by projecting the eigenstates onto the Arnold web, we find that eigenstates in the vicinity of the junctions are primarily delocalized due to dynamical tunneling. PMID- 30289719 TI - Discovery of a Branched Peptide That Recognizes the Rev Response Element (RRE) RNA and Blocks HIV-1 Replication. AB - We synthesized and screened a unique 46 656-member library composed of unnatural amino acids that revealed several hits against RRE IIB RNA. Among the hit peptides identified, peptide 4A5 was found to be selective against competitor RNAs and inhibited HIV-1 Rev-RRE RNA interaction in cell culture in a p24 ELISA assay. Biophysical characterization in a ribonuclease protection assay suggested that 4A5 bound to the stem-loop region in RRE IIB while SHAPE MaP probing with 234 nt RRE RNA indicated additional interaction with secondary Rev binding sites. Taken together, our investigation suggests that HIV replication is inhibited by 4A5 blocking binding of Rev and subsequent multimerization.

AB - The first asymmetric decarboxylative [4 + 3] annulation of propargylic carbamates with C, N-cyclic azomethine imines has been developed successfully by a copper- N heterocyclic carbine system. This strategy led to a series of optically active isoquinoline-fused triazepine derivatives in good yields and with excellent enantio- and diastereoselectivities. Remarkably, Cu-allenylidene intermediates play a crucial role in this transformation. PMID- 30289721 TI - Design, Synthesis, and Pharmacological Evaluation of Novel beta2/3 Subunit Selective gamma-Aminobutyric Acid Type A (GABAA) Receptor Modulators. AB - Subunit-selective modulation of gamma-aminobutyric acid type A receptors (GABAAR) is considered to exert fewer side effects compared to unselective clinically used drugs. Here, the beta2/3 subunit-selective GABAAR modulators valerenic acid (VA) and loreclezole (LOR) guided the synthesis of novel subunit-selective ligands with simplified structures. We studied their effects on GABAARs expressed in Xenopus laevis oocytes using two-microelectrode voltage clamp technique. Five compounds showed significantly more efficacious modulation of GABA-evoked currents than VA and LOR with retained potency and selectivity. Compound 18 [( E) 2-Cyano-3-(2,4-dichlorophenyl)but-2-enamide] induced the highest maximal modulation of GABA-induced chloride currents ( Emax: 3114 +/- 242%), while 12 [( Z)-3-(2,4-dichlorophenyl)but-2-enenitrile] displayed the highest potency (EC50: 13 +/- 2 MUM). Furthermore, in hippocampal neurons 12 facilitated phasic and tonic GABAergic inhibition, and in vivo studies revealed significantly more potent protection against pentylenetetrazole (PTZ)-induced seizures compared to VA and LOR. Collectively, compound 12 constitutes a novel, simplified, and subunit-selective GABAAR modulator with low-dose anticonvulsant activity. PMID- 30289723 TI - Sequential Prodrug Strategy To Target and Eliminate ACPA-Selective Autoreactive B Cells. AB - Autoreactive B cells are thought to play a pivotal role in many autoimmune diseases. Rheumatoid arthritis (RA) is an autoimmune disease affecting ~1% of the Western population and is hallmarked by the presence of anticitrullinated proteins antibodies (ACPA) produced by autoreactive B cells. We intend to develop a method to target and selectively eliminate these autoreactive B cells using a sequential antigen prodrug targeting strategy. As ACPA-expressing B cells are thought to play essential roles in RA-disease pathogenesis, we used this B cell response as a prototype to analyze the feasibility to generate a construct consisting of a biologically silenced, that is, blocked, antigen connected to a cytotoxic prodrug. Blocking of the antigen is considered relevant as it is anticipated that circulating autoantibodies will otherwise clear the antigen prodrug before it can reach the target cell. The antigen-prodrug can only bind to the autoantigen-specific B cell receptor (BCR) upon enzymatic removal of the blocking group in close proximity of the B cell surface. BCR binding ultimately induces antigen-specific cytotoxicity after internalization of the antigen. We have synthesized a cyclic citrullinated peptide (CCP) antigen suitable for BCR binding and demonstrated that binding by ACPA was impaired upon introduction of a carboxy- p-nitrobenzyl (CNBz) blocking group at the side chain of the citrulline residue. Enzymatic removal of the CNBz moiety by nitroreductase fully restored citrulline-specific recognition by both ACPA and ACPA-expressing B cells and showed targeted cell death of CCP-recognizing B cells only. These results mark an important step toward antigen-specific B cell targeting in general and more specifically in RA, as successful blocking and activation of citrullinated antigens forms the basis for subsequent use of such construct as a prodrug in the context of autoimmune diseases. PMID- 30289722 TI - Predicting the Binding of Fatty Acid Amide Hydrolase Inhibitors by Free Energy Perturbation. AB - Since a goal of most drug discovery projects in either academia or industry is to design molecules that selectively bind to the desired protein, determination of protein-ligand binding free energies is of utmost importance in computer aided drug design. With the help of significant improvements in computer power, enhanced sampling techniques and accuracy of force fields, FEP (free energy perturbation) is becoming an important tool to estimate binding free energies in many drug discovery projects both retrospectively and prospectively. We have evaluated the ability of Schrodinger's FEP+ to predict relative binding free energies of a congeneric series of noncovalent fatty acid amide hydrolase (FAAH) inhibitors using an in-house crystal structure. This study shows that although an impressively accurate correlation can be obtained with experimental IC50s considering small perturbations on the deeper side of the pocket, the same was not observed with small perturbations on the relatively more open-ended and solvent-accessible side of the pocket. To understand these observations, we thoroughly investigated several key factors including the sampling of asymmetrically substituted rings, different perturbation maps, impact of simultaneous perturbations at two different ends of the ligand, and selecting the perturbations in a "chemically sensible" way. PMID- 30289724 TI - UV-Responsive Behavior of Multistate and Multiscale Self-Assemblies Constructed by Gemini Surfactant 12-3-12.2Br- and trans- o-Methoxy-cinnamate. AB - Photoresponsive systems with adjustable self-assembly morphologies and tunable rheological properties have aroused widespread concern of researchers in recent years because of their prospect applications in controlled release, microfluidics, sensors, and so forth. In this paper, we combine a cationic Gemini surfactant 12-3-12.2Br- and trans-2-methoxy-cinnamate ( trans-OMCA) together to create a representative UV-responsive self-assembly system. The system displays abundant self-assembly behaviors, and the self-assemblies with different states and different scales including wormlike micelles, vesicles, and lyotropic liquid crystals (LCs) as well as an aqueous two-phase system (ATPS) are observed even at lower surfactant concentration. The UV-responsive behavior of the formed self assemblies is investigated systematically. The results have shown that the photoisomerization of OMCA from trans form to cis form under UV light irradiation alters the hydrophobicity and steric hindrance effect of OMCA and thus affects the molecular packing at the micellar interface and further leads to the transformation of assembly morphologies. The long wormlike micelles can gradually transform into much shorter rodlike micelles under UV irradiation and companied by the decrease of solution viscosity by 2 orders of magnitude. In addition, the vesicles can evolve into multistate self-assembly structures including the ATPS, wormlike micelles, rod-like micelles, and small spherical micelles depending on the UV irradiation time. The ATPS and its adjacent anisotropic LC phase can respectively combine into a single phase and separate into ATPS under UV irradiation. The morphologies of assemblies in the 12-3-12.2Br-/ trans-OMCA mixed system can be tailored by adjusting the system composition and duration of UV light irradiation on purpose. The photoresponsive system with abundant self assembly behaviors and tunable rheological properties has wide application prospect in numerous fields such as drug delivery, materials science, smart fluids, and so forth, and the macroscopic phase separation and combination provide novel strategies for effective separation and purification of certain substances. PMID- 30289725 TI - Synthesis and Property of Copper-Impregnated alpha-MnO2 Semiconductor Quantum Dots. AB - Because of the superior optical and electrical properties, copper-impregnated size tuneable high-temperature stable manganese dioxide semiconductor quantum dots (SQDs) have been successfully synthesized by a modified chemical synthesis technique. Their size-dependent dielectric properties, semiconducting properties, and current-voltage ( I- V) characteristics have been investigated. X-ray diffraction pattern and Raman spectra confirmed that the required phase is present. Because of the different sintering temperature tuneable size of SQDs has been found and confirmed by high-resolution transmission electron microscopy. The band gap energy of the material is found to be 1.25-1.67 eV, measured from Tauc plot using UV-vis absorbance spectrum and their semiconducting properties have been confirmed by the non linear current-voltage ( I- V) behavior. Most intense green emission peak of photoluminescence (PL) spectroscopy confirms the oxygen vacancy defect state. The stoke shifting of Raman spectra, UV absorption, and PL emission are the footprint of quantum confinement effect. Incorporation of a little amount of Cu in tetragonal hollandite structure of alpha-MnO2 generates strain within that structure. This leads to create sufficient crystal defect state as well as rise in dielectric constant accompanied with low dielectric loss and higher ac conductivity. All these highly desirable properties make the SQDs a potential candidate for developing multifunctional photo-electronic devices. Owing to the tuneable band gap and electronic transport of the SQDs, we realized that the controllable size paves the way for designing SQDs possessing unique properties for optical and electronic device applications. Using this material as a high dielectric separator, a high-performance supercapacitor has been successfully fabricated which can light up 15 light-emitting diodes for 47 min 23 s after charging them only for 30 s. PMID- 30289726 TI - Scalable Microfluidic Platform for Flexible Configuration of and Experiments with Microtissue Multiorgan Models. AB - Microphysiological systems hold the promise to increase the predictive and translational power of in vitro substance testing owing to their faithful recapitulation of human physiology. However, the implementation of academic developments in industrial settings remains challenging. We present an injection molded microfluidic microtissue (MT) culture chip that features two channels with 10 MT compartments each and that was designed in compliance with microtiter plate standard formats. Polystyrene as a chip material enables reliable, large-scale production and precise control over experimental conditions due to low adsorption or absorption of small, hydrophobic molecules at or into the plastic material in comparison with predecessor chips made of polydimethylsiloxane. The chip is operated by tilting, which actuates gravity-driven flow between reservoirs at both ends of every channel, so that the system does not require external tubing or pumps. The flow rate can be modulated by adjusting the tilting angle on demand. The top-open design of the MT compartment enables efficient MT loading using standard or advanced pipetting equipment, ensures oxygen availability in the chip, and allows for high-resolution imaging. Every channel can be loaded with up to 10 identical or different MTs, as demonstrated by culturing liver and tumor MTs in the same medium channel on the chip. PMID- 30289727 TI - The Influence of Temperature on Embryonic Respiration, Growth, and Sex Determination in a Western Australian Population of Green Turtles (Chelonia mydas). AB - The thermal environment of sea turtle embryos has marked effects on many aspects of their development and energetics and has consequences for posthatching stages. Here we incubated Chelonia mydas embryos from Ningaloo Reef in Western Australia at a range of temperatures (27 degrees , 29 degrees , 30 degrees , 31 degrees , 32 degrees , and 30 degrees +/- 5 degrees C) to determine development rates and the pivotal temperature for sex determination. We also measured embryonic growth, oxygen consumption, and carbon dioxide production throughout development at 27 degrees and 31 degrees C. Metabolic rates were higher at 31 degrees C than at 27 degrees C, but total energy expenditure was greater at 27 degrees C, with 2,281 mL of oxygen consumed compared with 1,992 mL at 31 degrees C. Respiration at both temperatures showed a pattern typical of sea turtle embryos, with peak rates occurring at approximately 85% of development and then declining toward hatching. Hatchlings produced at higher incubation temperatures developed faster, were smaller, and had larger residual yolk masses than hatchlings produced at lower temperatures. The pivotal temperature that produced an equal sex ratio was 29.2 degrees C, with mixed sexes produced between 27.9 degrees and 30.4 degrees C. Our results showed that the Ningaloo population of C. mydas has somewhat different thermal sensitivities than other C. mydas populations and justified why is it necessary to collect population-specific data to accurately project the impacts of global warming on focal populations. PMID- 30289728 TI - Pharmacotherapeutic management of comorbid polycystic ovary syndrome and diabetes. AB - INTRODUCTION: Polycystic ovary syndrome (PCOS) is a common endocrine disorder in premenopausal women. Insulin resistance and glucose intolerance are very prevalent metabolic complications in women with PCOS, especially in those presenting with weight excess. Therapeutic strategies targeting insulin resistance in PCOS are of interest because of their overall safety and their beneficial effects on metabolic and reproductive features. Areas covered: The authors review systematically all of the available therapeutic interventions targeting insulin resistance and/or disturbances of glucose metabolism in women with PCOS. Expert opinion: The diagnosis of glucose tolerance disorders in women with PCOS requires an oral glucose tolerance test. Strategies addressing weight excess and abdominal adiposity, from lifestyle modification to insulin sensitizers, may improve insulin resistance and glucose tolerance in women with PCOS. However, amelioration of signs and symptoms of PCOS usually requires the loss of large amounts of weight for it to be noticeable. Bariatric surgery has emerged as the most successful approach for obese patients with PCOS, because glucose intolerance, diabetes, and PCOS resolve in most cases through follow-ups. At present, the role of novel drugs targeting insulin resistance and/or diabetes such as inositols, berberine, resveratrol, and incretin-based therapies are yet to be properly established. PMID- 30289729 TI - Mutation Profiles in Glioblastoma 3D Oncospheres Modulate Drug Efficacy. AB - Glioblastoma (GBM) is a lethal brain cancer with a median survival time of approximately 15 months following treatment. Common in vitro GBM models for drug screening are adherent and do not recapitulate the features of human GBM in vivo. Here we report the genomic characterization of nine patient-derived, spheroid GBM cell lines that recapitulate human GBM characteristics in orthotopic xenograft models. Genomic sequencing revealed that the spheroid lines contain alterations in GBM driver genes such as PTEN, CDKN2A, and NF1. Two spheroid cell lines, JHH 136 and JHH-520, were utilized in a high-throughput drug screen for cell viability using a 1912-member compound library. Drug mechanisms that were cytotoxic in both cell lines were Hsp90 and proteasome inhibitors. JHH-136 was uniquely sensitive to topoisomerase 1 inhibitors, while JHH-520 was uniquely sensitive to Mek inhibitors. Drug combination screening revealed that PI3 kinase inhibitors combined with Mek or proteasome inhibitors were synergistic. However, animal studies to test these drug combinations in vivo revealed that Mek inhibition alone was superior to the combination treatments. These data show that these GBM spheroid lines are amenable to high-throughput drug screening and that this dataset may deliver promising therapeutic leads for future GBM preclinical studies.

AB - INTRODUCTION: Malaria in pregnancy continues to be a significant public health burden globally, with over 100 million women at risk each year. Sulfadoxine pyrimethamine (SP) is the only antimalarial recommended for intermittent preventive therapy in pregnancy (IPTp) but increasing parasite resistance threatens its viability. There are few other available antimalarial therapies that currently have sufficient evidence of tolerability, safety, and efficacy to replace SP. Areas covered: Novel antimalarial combinations are under investigation for potential use as chemoprophylaxis and in IPTp regimens. The present review summarizes currently available therapies, emerging candidate combination therapies, and the potential challenges to integrating these into mainstream policy. Expert opinion: Alternative drugs or combination therapies to SP for IPTp are desperately required. Dihydroartemisinin-piperaquine and azithromycin-based combinations are showing great promise as potential candidates for IPTp but pharmacokinetic data suggest that dose modification may be required to ensure adequate prophylactic efficacy. If a suitable candidate regimen is not identified in the near future, the success of chemopreventive strategies such as IPTp may be in jeopardy.

PMID- 30289732 TI - Adjuvant Gemcitabine Plus Docetaxel Followed by Doxorubicin Versus Observation for High-Grade Uterine Leiomyosarcoma: A Phase III NRG Oncology/Gynecologic Oncology Group Study. AB - PURPOSE: We conducted a randomized phase III trial to determine whether adjuvant chemotherapy improves survival in women with uterine leiomyosarcoma. METHODS: Women with uterus-confined, high-grade leiomyosarcoma who were confirmed disease free by imaging were randomly assigned to four cycles of gemcitabine plus docetaxel, followed by four cycles of doxorubicin, or to observation. All were followed for evidence of recurrence. The primary end point was overall survival (OS). RESULTS: With international collaboration, 38 of the targeted accrual of 216 patients were enrolled, after which the study was closed by the National Cancer Institute for accrual futility. Twenty patients were assigned to chemotherapy, 18 to observation. Among the 17 patients treated with at least one cycle of chemotherapy, grade 3 or 4 toxicities were observed in 47%; among the 18 patients assigned to observation, one had grade 3 hypertension. There were six deaths (chemotherapy, n = 5; observation, n = 1), all due to disease. The restricted mean survival time for OS was estimated as 34.3 months (95% CI, 25.3 to 43.3 months) in the chemotherapy arm and as 46.4 months (95% CI, 43.6 to 49.1 months) in the observation arm. There were eight recurrences in each arm. The restricted mean survival time for recurrence-free survival was estimated as 18.1 (95% CI, 14.2 to 22.0) months in the chemotherapy arm and as 14.6 months (95% CI, 10.3 to 19.0 months) in the observation arm. Neither survival outcome comparison was considered statistically robust, due to the small sample size. CONCLUSION: Despite international collaboration to test the role of adjuvant chemotherapy in uterine-confined leiomyosarcoma, this study was closed for accrual futility. Although the sample size precludes robust statistical comparison, observed OS and recurrence-free survival data do not show superior outcomes with adjuvant chemotherapy. PMID- 30289734 TI - IgG4-related Cardiovascular Disease from the Aorta to the Coronary Arteries: Multidetector CT and PET/CT. AB - Immunoglobulin G4 (IgG4)-related disease can affect the cardiovascular system, including the coronary arteries and pericardium and especially the walls of large and medium-sized vessels. The presence of coronary involvement is critical, as this condition can cause myocardial ischemia or sudden cardiac death. Although histopathologic examination remains the reference standard for detecting organ involvement and diagnosing IgG4-related disease, obtaining biopsy or surgical specimens from the vessel wall is still challenging. Because patients may be only mildly symptomatic, noninvasive imaging evaluation of IgG4-related cardiovascular disease (CVD) has an essential role in not only the diagnosis but also the management of this condition. Multidetector CT is a useful noninvasive examination for establishing the primary diagnosis and defining anatomic landmarks and their relationships. The spectrum of vessel involvement is vast, with varied manifestations. Radiologists should be familiar with inflammatory vasculitis, aneurysmal change, and pseudotumor formation in all vessels and the distribution of these conditions throughout the body. Electrocardiographically gated CT enables accurate, fast, and noninvasive characterization of coronary pathologic conditions and thus has an important advantage over catheter angiography. Combined PET/CT can depict inflammatory processes and help distinguish IgG4-related CVD from atherosclerosis. Familiarity with the PET/CT and CT findings of inflammatory processes involved in IgG4-related CVD is important for accurate diagnosis and evaluation of therapeutic response during follow-up. The multidetector CT and PET/CT characteristics of IgG4-related CVD, such as aortitis, periaortitis, arteritis, and periarteritis and including coronary artery involvement and pericarditis, are reviewed. In addition, the inflammatory process, quantification of active inflammation, and therapeutic response during follow-up associated with IgG4-related CVD are described.

AB - The Liver Imaging Reporting and Data System (LI-RADS) standardizes performance of liver imaging in patients at risk for hepatocellular carcinoma (HCC) as well as interpretation and reporting of the results. Developed by experts in liver imaging and supported by the American College of Radiology, LI-RADS assigns to observations categories that reflect the relative probability of benignity, HCC, or other malignancy. While category assignment is based mainly on major imaging features, ancillary features may be applied to improve detection and characterization, increase confidence, or adjust LI-RADS categories. Ancillary features are classified as favoring malignancy in general, HCC in particular, or benignity. Those favoring malignancy in general or HCC in particular may be used to upgrade by a maximum of one category up to LR-4; those favoring benignity may be used to downgrade by a maximum of one category. If there are conflicting ancillary features (ie, one or more favoring malignancy and one or more favoring benignity), the category should not be adjusted. Ancillary features may be seen at diagnostic CT, MRI performed with extracellular agents, or MRI performed with hepatobiliary agents, with the exception of one ancillary feature assessed at US. This article focuses on LI-RADS version 2018 ancillary features seen at MRI. Specific topics include rules for ancillary feature application; definitions, rationale, and illustrations with clinical MRI examples; summary of evidence and diagnostic performance; pitfalls; and future directions.

AB - BACKGROUND:: Transitioning low-risk cancer survivors back to their primary care provider (PCP) has been shown to be safe but the effect on health system resources and costs has not been examined. METHODS:: A Well Follow-Up Care Initiative (WFCI) was implemented in the publicly funded health system. Low-risk breast cancer (BC) survivors in the WFCI intervention group were transitioned from oncologist-led cancer clinics to PCPs. We compared health system costs ($2,014 in Canadian dollars) and resource utilization in this intervention group with that in propensity-score-matched nontransitioned BC survivors (ie, controls) diagnosed in the same year, with similar disease profile and patient characteristics using publicly funded administrative databases. RESULTS:: A total of 2,324 BC survivors from the WFCI intervention group were 1:1 matched to controls and observed for 25 months. Compared with controls, survivors in the intervention group incurred a similar number of PCP visits (6.9 v 7.5) and fewer oncologist visits (0.3 v 1.2) per person-year. Fewer survivors in the intervention group (20.1%) were hospitalized than in the control group (24.4%). There were no differences in emergency visits. More survivors in the intervention group had mammograms (82.6% v 73.1%), but other diagnostic tests were less frequent. There was a 39.3% reduction in overall mean annual costs ($6,575 v $10,832) and a 22.1% reduction in overall median annual costs ($2,261 v $2,903). Overall survival in the intervention group was not worse than controls. CONCLUSION:: Transitioning low-risk BC survivors to PCPs was associated with lower health system resource use and a lower annual cost per patient than matched controls. The WFCI model represents a reasonable approach at the population level to delivering quality care for low-risk BC survivors that seems to be cost effective. PMID- 30289737 TI - Returning Results to Family Members: Professional Duties in Genomics Research in the United States. AB - This article critically appraises the ethical and legal duties to disclose findings to the family members of research participants. These family members stand to benefit in important ways from discoveries that can inform their own health and reproductive risks. However, careful appreciation of how medical research differs from clinical practice and of the uncertainties at stake in genomic research complicates any warning to relatives. Research laboratories should generally be immune from liability for failing to diagnose or disclose a genetic disorder in time to prevent adverse outcomes for a participant's family members or to return properly interpreted test results for even direct findings under investigation, let alone incidental ones. The only exception is where warning relatives of medical risks is very likely to prevent imminent harm and would not override known participant wishes. Genomic autopsy studies for sudden death satisfy these conditions of life-saving potential for relatives without disrespect to subjects. These are among the rare instances in which we conclude that offering results to family members is not just permissible but obligatory, not just as a moral matter but as a legal one.

AB - BACKGROUND: Pediatric sports specialization, defined as intense year-round training in a single sport as a result of excluding other sports for more than 8 months per year, is common in the United States. There are demonstrated physical and social risks to early pediatric sports specialization (defined as before age 12 years). While thought to be needed to acquire appropriate experience and excel in a given sport, there remains little information on when athletes at the highest levels of their sport specialized. This study aimed to define when professional and collegiate ice hockey players specialized. HYPOTHESIS: Early sports specialization before age 12 years will not be common among elite-level (professional and collegiate) ice hockey players. STUDY DESIGN: Retrospective cross-sectional survey study. LEVEL OF EVIDENCE: Level 3. METHODS: Male professional and collegiate ice hockey players within 1 National Hockey League organization and 2 National Collegiate Athletic Association (NCAA) organizations who were 18 years of age or older completed a survey at training camp detailing their history of sports participation and specialization. RESULTS: A total of 91 athletes participated in the study (mean age, 22.8 years; range, 18-39 years). The mean age at the start of any sports participation was 4.5 years, and the mean age of sports specialization was 14.3 years. The mean age of specialization in the professional group, the NCAA Division I group, and the NCAA Division III group was 14.1, 14.5, and 14.6 years, respectively. CONCLUSION: Early pediatric sports specialization is not common in elite-level (professional and collegiate) ice hockey players. CLINICAL RELEVANCE: Early pediatric sports specialization before age 12 years is not necessary for athletic success in professional and collegiate ice hockey. This study provides further evidence supporting the recommendations of the American Medical Society for Sports Medicine, American Academy of Pediatrics, and American Orthopaedic Society for Sports Medicine against early sports specialization. PMID- 30289743 TI - NRG1 PLGA MP locally induce macrophage polarisation toward a regenerative phenotype in the heart after acute myocardial infarction. AB - Neuregulin-1 loaded poly(lactic-co-glycolic acid) (PLGA) microparticles hold great promise for treating acute myocardial infarction, as they have been proved to recover heart function and induce positive heart remodelling in preclinical studies. More recently, the inflammatory response of the heart after acute myocardial infarction (AMI) has been identified as one of the major mechanisms in cardiac tissue remodelling and repair. However, the connection between neuregulin 1 PLGA microparticles and inflammation is still not well characterised. In the present study we assessed this relationship in a mouse AMI model. First, in vitro evidence indicated that neuregulin-1 PLGA microparticles induced a macrophage polarisation toward a regenerative phenotype (CD206+ cells), preventing macrophages from evolving toward the inflammatory phenotype (B7-2+ cells). This correlated with in vivo experiments, where neuregulin-1 PLGA microparticles locally improved the CD206+/B7-2+ ratio. Moreover, neuregulin-1 PLGA microparticles were administered at different time points (15 min, 24, 72 and 168 h) after infarction induction without causing secondary inflammatory issues. The time of treatment administration did not alter the inflammatory response. Taken together, these results suggest that neuregulin-1 PLGA microparticles can be administered depending on the therapeutic window of the encapsulated drug and that they enhance the heart's reparative inflammatory response after acute myocardial infarction, helping cardiac tissue repair. PMID- 30289745 TI - Proteome and transcriptome profiling of equine myofibrillar myopathy identifies diminished peroxiredoxin 6 and altered cysteine metabolic pathways. AB - Equine myofibrillar myopathy (MFM) causes exertional muscle pain and is characterized by myofibrillar disarray and ectopic desmin aggregates of unknown origin. To investigate the pathophysiology of MFM, we compared resting and 3 h post-exercise transcriptomes of gluteal muscle and the resting skeletal muscle proteome of MFM and control Arabian horses using RNA-sequencing and iTRAQ analyses. Three hours after exercise, 191 genes were identified as differentially expressed (DE) in MFM vs. control muscle with > 1 log2 fold change [FC] in genes involved in sulfur compound/ cysteine metabolism such as cystathionine-beta synthase [CBS, ?4.51], a cysteine and neutral amino acid membrane transporter [SLC7A10, ?1.80 MFM] and a cationic transporter [SLC24A1, ?1.11 MFM). In MFM vs. control at rest, 284 genes were DE with > 1 log2 FC in pathways for structure morphogenesis, fiber organization, tissue development and cell differentiation including> 1 log2 FC in cardiac alpha actin [ACTC1 ?2.5 MFM], cytoskeletal desmoplakin [DSP ?2.4 MFM] and basement membrane usherin [USH2A ?2.9 MFM]. Proteome analysis revealed significantly lower antioxidant peroxiredoxin 6 content (PRDX6, ?4.14 log2 FC MFM), higher fatty acid transport enzyme carnitine palmitoyl transferase (CPT1B, ?3.49 MFM) and lower sarcomere protein tropomyosin (TPM2, ?3.24 MFM) in MFM vs. control muscle at rest. We propose that in MFM horses, altered cysteine metabolism and a deficiency of cysteine-containing antioxidants combined with a high capacity to oxidize fatty acids and generate ROS during aerobic exercise causes chronic oxidation and aggregation of key proteins such as desmin.

AB - Total number born(TNB),number born alive(NBA)and litter weight born alive(LWB)are critically important traits in pig production.The sow's parity is one of the major factors influencing litter traits.Because of monogenic or polygenic contributions and the presence of temporal gene effects in different sows' parities,it is difficult to clarify the biological and genetic background.To systematically explore the genetic mechanism of litter traits,18 GWASs were conducted using single-step GWAS(ssGWAS) based on two breeds(908 Landrace and 1130 Large White sow litter records)for each litter trait in different parities.A total of 300 Landrace and 300 Large White sows were genotyped by sequencing(GBS).ssGWAS was performed separately for each breed and each parity due to population stratification and temporal gene effect.In summary,we identified 80(15 for Landrace and 65 for Large White),227(52 for Landrace,175 for Large White),and 187(34 for Landrace,153 for Large White) SNPs affecting TNB,NBA and LWB respectively.Of them,we suggested that a total of 22 loci were shared by TNB,NBA and LWB.These results indicated the existence of gene temporal effect in each parity.Furthermore,our findings suggested four interesting candidate genes (FBXL7,ALDH1A2,LEPR and DDX1)associated with litter traits in different parities that have a major effect on embryonic development progression.In conclusion,22 crucial SNPs and 4 interesting candidate genes were identified for three litter traits across six parities.These findings advance our understanding of the genetic architecture of litter traits and confirm the presence of temporal gene effects in different parities.Importantly, functional validation studies for findings of particular interest are recommended in litter traits. PMID- 30289747 TI - A Transcriptomic Analysis of the Development of Skeletal Muscle Atrophy in Cancer Cachexia in Tumor-Bearing Mice. AB - Cancer-Cachexia (CC) is a wasting condition directly responsible for 20-40% of cancer-related deaths. The mechanisms controlling development of CC-induced muscle wasting are not fully elucidated. Most investigations focus on the post cachectic state and do not examine progression of the condition. We recently demonstrated mitochondrial degenerations precede muscle wasting in time course progression of CC. However, the extent of muscle perturbations prior to wasting in CC is unknown. Therefore, we performed global gene expression analysis in CC induced muscle wasting to enhance understanding of intramuscular perturbations across the development of CC. Lewis Lung Carcinoma (LLC) was injected into the hind-flank of C57BL6/J mice at 8 wks age with tumor allowed to develop for 1, 2, 3, or 4 wks and compared to PBS injected control. Muscle wasting was evident at 4 wks LLC. RNA sequencing of gastrocnemius muscle samples showed widespread alterations in LLC compared to PBS animals with largest differences seen in 4 wk LLC suggesting extensive transcriptomic alterations concurrent to muscle wasting. Commonly altered pathways included: Mitochondrial Dysfunction and Protein Ubiquitination, along with other less studied processes in this condition regulating transcription/translation and cytoskeletal structure. Current findings present novel evidence of transcriptomic shifts and altered cellular pathways in CC-induced muscle wasting. PMID- 30289748 TI - Role of phosphatidylcholine-DHA in preventing APOE4-associated Alzheimer's disease. AB - Dietary and supplemental intake of the omega-3 fatty acid docosahexaenoic acid (DHA) reduces risk of Alzheimer's disease (AD) and ameliorates symptoms. The apolipoprotein E ( APOE) 4 allele is the strongest risk factor for sporadic AD, exclusive of age. APOE4 carriers respond well to the DHA present in fish but do not respond as well to dietary supplements. The mechanisms behind this varied response remain unknown. I posit that the difference is that fish contain DHA in phospholipid form, whereas fish oil supplements do not. This influences whether DHA is metabolized to nonesterified DHA (free DHA) or a phospholipid form called lysophosphatidylcholine DHA (DHA-lysoPC). Free DHA is transported across the outer membrane leaflet of the blood-brain barrier (BBB) via passive diffusion, and DHA-lysoPC is transported across the inner membrane leaflet of the BBB via the major facilitator superfamily domain-containing protein 2A. I propose that APOE4 carriers have impaired brain transport of free DHA but not of DHA-lysoPC, as a consequence of a breakdown in the outer membrane leaflet of the BBB, putting them at increased risk for AD. Dietary sources of DHA in phospholipid form may provide a means to increase plasma levels of DHA-lysoPC, thereby decreasing the risk of AD.-Patrick, R. P.

AB - Obesity is a major public health problem worldwide. In the United States, one third of women of reproductive age are obese. Human studies show that maternal obesity (MO) predisposes offspring to cardiovascular disease. However, the underlying mechanisms remain unclear. Given the similarities between pregnancy in sheep and humans, we studied sheep to examine the impact of MO on fetal cardiomyocyte contractility at term. We observed that MO impaired cardiomyocyte contractility by reducing peak shortening and shortening/relengthening velocity, prolonging time to relengthening. MO disrupted Ca2+ homeostasis in fetal cardiomyocytes, increasing intracellular Ca2+ and inducing cellular Ca2+ insensitivity. The Ca2+-release channel was impaired, but Ca2+ uptake was unaffected by MO. The upstream kinases that phosphorylate the Ca2+-release channel-ryanodine receptor-2, PKA, and calmodulin-dependent protein kinase II were activated in MO fetuses. Contractile dysfunction was associated with an increased ratio of myosin heavy chain (MHC)-beta to MHC-alpha and upregulated cardiac troponin (cTn)-T and tropomyosin, as well as cTn-I phosphorylation. In summary, this is the first characterization of the effects of MO on fetal cardiomyocyte contractility. Our findings indicate that MO impairs fetal cardiomyocyte contractility through altered intracellular Ca2+ handling, overloading fetal cardiomyocyte intracellular Ca2+ and aberrant myofilament protein composition. These mechanisms may contribute to developmental programming by MO of offspring cardiac function and predisposition to later life cardiovascular disease in the offspring.-Wang, Q., Zhu, C., Sun, M., Maimaiti, R., Ford, S.

PMID- 30289750 TI - Deletion in mice of X-linked, Brugada syndrome- and atrial fibrillation associated Kcne5 augments ventricular KV currents and predisposes to ventricular arrhythmia. AB - KCNE5 is an X-linked gene encoding KCNE5, an ancillary subunit to voltage-gated potassium (KV) channels. Human KCNE5 mutations are associated with atrial fibrillation (AF)- and Brugada syndrome (BrS)-induced cardiac arrhythmias that can arise from increased potassium current in cardiomyocytes. Seeking to establish underlying molecular mechanisms, we created and studied Kcne5 knockout ( Kcne5-/0) mice. Intracardiac ECG revealed that Kcne5 deletion caused ventricular premature beats, increased susceptibility to induction of polymorphic ventricular tachycardia (60 vs. 24% in Kcne5+/0 mice), and 10% shorter ventricular refractory period. Kcne5 deletion increased mean ventricular myocyte KV current density in the apex and also in the subpopulation of septal myocytes that lack fast transient outward current ( Ito,f). The current increases arose from an apex-specific increase in slow transient outward current-1 ( IKslow,1) (conducted by KV1.5) and Ito,f (conducted by KV4) and an increase in IKslow,2 (conducted by KV2.1) in both apex and septum. Kcne5 protein localized to the intercalated discs in ventricular myocytes, where Kv2.1 was also detected in both Kcne5-/0 and Kcne5+/0 mice. In HL-1 cardiac cells and human embryonic kidney cells, KCNE5 and Kv2.1 colocalized at the cell surface, but predominantly in intracellular vesicles, suggesting that Kcne5 deletion increases IK,slow2 by reducing Kv2.1 intracellular sequestration. The human AF-associated mutation KCNE5-L65F negative shifted the voltage dependence of KV2.1-KCNE5 channels, increasing their maximum current density >2-fold, whereas BrS-associated KCNE5 mutations produced more subtle negative shifts in KV2.1 voltage dependence. The findings represent the first reported native role for Kcne5 and the first demonstrated Kcne regulation of KV2.1 in mouse heart. Increased KV current is a manifestation of KCNE5 disruption that is most likely common to both mouse and human hearts, providing a plausible mechanistic basis for human KCNE5-linked AF and BrS.-David, J-P., Lisewski, U., Crump, S.

A practical approach to identifying an underlying cause is to first screen for common ones and then proceed with further testing as needed. Treatment consists of correcting the underlying cause, managing pain, and modifying lifestyle. PMID- 30289759 TI - When stroke runs in the family.

The paragraph should read as follows: The exact pathogenesis of alcoholic hepatitis is incompletely understood, but alcohol is primarily metabolized by the liver, and damage likely occurs during metabolism of the ingested alcohol. AST elevations tend to be higher than ALT elevations; the reason is ascribed to hepatic deficiency of pyridoxal 5'-phosphate, a cofactor of the enzymatic activity of ALT, which leads to a lesser increase in ALT than in AST.

PMID- 30289765 TI - Operative Management of Abdominal Wound Dehiscence: Outcomes and Factors Influencing Time to Healing in Patients Undergoing Surgical Debridement With Primary Closure. AB - INTRODUCTION: Plastic surgeons are often consulted by other surgical teams for management of wound dehiscence following abdominopelvic surgery. OBJECTIVE: The purpose of this study is to determine whether operative debridement and primary closure of abdominopelvic wounds are safe and expeditious for patients. MATERIALS AND METHODS: A retrospective analysis was conducted on a database of patients who underwent operative debridement and closure at a single institution between January 2011 and December 2015 for dehisced abdominal or pelvic wounds acquired from prior obstetric, gynecologic, transplant, plastic, or general surgery procedures. RESULTS: Of the 163 patient records identified, 43 patients met inclusion criteria. The median time from final debridement and primary surgical closure to complete wound healing was 27 days. Time to healing differed significantly by index procedure type (P = .004), with obstetric procedures requiring the shortest median time (12.0 days) and general surgery procedures requiring the longest (39.5 days). Wound healing took 3.6 times longer for patients with diabetes (P = .046) and 11.4 times longer for patients who experienced delayed superficial wound healing or redehiscence (P = .003). Nevertheless, with the exception of 4 patients who died of other causes, all wounds (39/39; 100%) achieved complete wound closure. CONCLUSIONS: Operative debridement and closure of abdominopelvic wound dehiscence through a multidisciplinary team approach with plastic surgery results in expeditious wound healing with minimal complications, and it may be safer and more cost effective than healing by secondary intention. PMID- 30289766 TI - Scaling of resistive random access memory devices beyond 100 nm2: influence of grain boundaries studied using scanning tunneling microscopy. AB - Resistive Random Access Memory (ReRAM) has emerged as the successor to FLASH in memory technology due to its multi-level fabrication possibilities and prospects of scaling down virtually to atomic dimensions. However, as we report here, when polycrystalline switching materials are used, the ReRAM devices scaled down to the sub-5 nm2 area show complete randomness due to inhomogeneous conductance values of grains and grain boundaries. By measuring the switching properties of grains and grain boundaries individually using a scanning tunneling microscope, we demonstrate that the doublet and triplet grain boundaries behave like degenerate semiconductors and act as conduction channels that bypass the resistive switching of the devices. Fabricating virtual devices using gold clusters deposited on top, we show that the random distribution of such highly conducting grain boundaries reduces the reliability of nano-scale ReRAM devices when scaled down to the sub-10 nm scale. PMID- 30289767 TI - Sexual Counseling Provided by Cardiovascular Nurses: Attitudes, Beliefs, Perceived Barriers, and Proposed Solutions. AB - BACKGROUND: Although sex lives of patients with cardiovascular disease (CVD) are affected in various ways and degrees, nurses working with these patients refrain from talking about sexual matters with their patients or encounter barriers trying to do so. OBJECTIVE: The purpose of this descriptive study was to identify attitudes and beliefs of cardiovascular nurses regarding talking to their patients about sexual problems, perceived barriers, and proposed solutions. METHODS: The sample included 170 nurses working for the cardiology and cardiac surgery departments of 1 university hospital, 2 ministry of health hospitals, and 2 private hospitals in Turkey. Data were collected between April and August 2015 through a 4-section questionnaire including the Sexual Attitude and Beliefs Scale. Descriptive, parametric, and nonparametric statistics were used to analyze the data. RESULTS: Most (73.5%) reported not talking to their patients about sexual issues, and only 35.9% stated that they had been educated on how to do so. The major reason for nurses avoiding discussions about sex with their patients was not considering sexuality as a patient care priority (86.4%). Establishing privacy for the patient (91.2%) was the solution proposed by most nurses. The average score of the nurses on the Sexual Attitude and Beliefs Scale was only medium. CONCLUSION: Most of the nurses were untrained about how to talk about sexual problems with their patients and therefore were unable to talk about it freely. PMID- 30289768 TI - Mental health and wellbeing during the transition to fatherhood: a systematic review of first time fathers' experiences. AB - OBJECTIVE: The aim of this systematic review was to identify and synthesize the best available evidence on first time fathers' experiences and needs in relation to their mental health and wellbeing during their transition to fatherhood. INTRODUCTION: Men's mental health and wellbeing during their transition to fatherhood is an important public health issue that is currently under-researched from a qualitative perspective and poorly understood. INCLUSION CRITERIA: Resident first time fathers (biological and non-biological) of healthy babies born with no identified terminal or long-term conditions were included. The phenomena of interest were their experiences and needs in relation to mental health and wellbeing during their transition to fatherhood, from commencement of pregnancy until one year after birth. Studies based on qualitative data, including, but not limited to, designs within phenomenology, grounded theory, ethnography and action research were included. METHODS: A three-step search strategy was used. The search strategy explored published and unpublished qualitative studies from 1960 to September 2017. All included studies were assessed by two independent reviewers and any disagreements were resolved by consensus or with a third reviewer. The recommended Joanna Briggs Institute (JBI) approach to critical appraisal, study selection, data extraction and data synthesis was used. RESULTS: Twenty-two studies met the eligibility criteria and were included in the review, which were then assessed to be of moderate to high quality (scores 5-10) based on the JBI Critical Appraisal Checklist for Qualitative Research. The studies were published between 1990 and 2017, and all used qualitative methodologies to accomplish the overall aim of investigating the experiences of expectant or new fathers. Nine studies were from the UK, three from Sweden, three from Australia, two from Canada, two from the USA, one from Japan, one from Taiwan and one from Singapore. The total number of first time fathers included in the studies was 351. One hundred and forty-four findings were extracted from the included studies. Of these, 142 supported findings were aggregated into 23 categories and seven synthesized findings: 1) New fatherhood identity, 2) Competing challenges of new fatherhood, 3) Negative feelings and fears, 4) Stress and coping, 5) Lack of support, 6) What new fathers want, and 7) Positive aspects of fatherhood. CONCLUSIONS: Based on the synthesized findings, three main factors that affect first time fathers' mental health and wellbeing during their transition to fatherhood were identified: the formation of the fatherhood identity, competing challenges of the new fatherhood role and negative feelings and fears relating to it. The role restrictions and changes in lifestyle often resulted in feelings of stress, for which fathers used denial or escape activities, such as smoking, working longer hours or listening to music, as coping techniques. Fathers wanted more guidance and support around the preparation for fatherhood, and partner relationship changes. Barriers to accessing support included lack of tailored information resources and acknowledgment from health professionals. Better preparation for fatherhood, and support for couple relationships during the transition to parenthood could facilitate better experiences for new fathers, and contribute to better adjustments and mental wellbeing in new fathers.

PMID- 30289769 TI - Assessing the Feasibility of Providing a Real-Time Response to Seizures Detected With Continuous Long-Term Neonatal Electroencephalography Monitoring. AB - PURPOSE: Continuous video electroencephalography (cEEG) monitoring is the recommended gold standard of care for at-risk neonates but is not available in many Neonatal Intensive Care Units (NICUs). To conduct a randomized treatment trial of levetiracetam for the first-line treatment of neonatal seizures (the NEOLEV2 trial), we developed a monitoring infrastructure at five NICUs, implementing recent technological advancements to provide continuous video EEG monitoring and real-time response to seizure detection. Here, we report on the feasibility of providing this level of care. METHODS: Twenty-five key informant interviews were conducted with study neurologists, neonatologists, coordinators, and EEG technicians from the commercial EEG monitoring company Corticare. A general inductive approach was used to analyze these qualitative data. RESULTS: A robust infrastructure for continuous video EEG monitoring, remote review, and real-time seizure detection was established at all sites. At the time of this survey, 260 babies had been recruited and monitored for 2 to 6 days. The EEG technician review by the commercial EEG monitoring company was reassuring to families and neonatologists and led to earlier detection of seizures but did not reduce work load for neurologists. Neurologists found the automated neonatal seizure detector algorithm provided by the EEG software company Persyst useful, but the accuracy of the algorithm was not such that it could be used without review by human expert. Placement of EEG electrodes to initiate monitoring, especially after hours, remains problematic. CONCLUSIONS: Technological advancements have made it possible to provide at-risk neonates with continuous video EEG monitoring, real-time detection of and response to seizures. However, this standard of care remains unfeasible in usual clinical practice. Chief obstacles remain starting a recording and resourcing the real-time specialist review of suspect seizures.

AB - Epithelioid fibrous histiocytoma (EFH) is a rare lesion believed to arise from dermal microvascular unit fibroblasts and dendritic histiocytes. EFH has long been considered a morphologic variant of benign fibrous histiocytoma (dermatofibroma), with prominent epithelioid cytomorphology that can mimic both vascular and melanocytic neoplasms. The molecular basis for the relationship between EFH and benign fibrous histiocytoma has remained largely unknown, with some authors suggesting that EFH represents an entity that is biologically distinct from benign fibrous histiocytoma. Recent molecular studies have identified the presence of recurrent anaplastic lymphoma kinase (ALK) gene rearrangements, a phenomenon that has not been described in benign fibrous histiocytoma. These new molecular findings highlight the uniqueness of this rare tumor and may prove useful as a diagnostic tool for differentiation from other histologic mimics. PMID- 30289774 TI - The Delicate Balance: Managing Oxygen Treatment in Neonates. AB - This review is based on a Mallinckrodt Pharmaceuticals-sponsored presentation, "The Delicate Balance of Managing Oxygen Treatment in Neonates," delivered by Amy R Koehn, PhD, NNP-BC, at the National Association of Neonatal Nurses (NANN) 33rd Annual Conference, held in Providence, Rhode Island on October 11, 2017. In addition to focusing on the potential risks associated with exposing newborn tissues to episodes of lower (hypoxic) and higher (hyperoxic) than normal concentrations of serum oxygen, the current guidance for target saturation ranges and methods of tissue oxygenation measurements in neonates was reviewed. A total of 181 neonatal nurses, neonatal nurse practitioners, nurse educators, and nurse managers were polled during the presentation using an audience response system (ARS). Results from this poll and two similar polls from previous years are discussed. PMID- 30289775 TI - Enhanced triage for patients with suspected cardiac chest pain: the History and Electrocardiogram-only Manchester Acute Coronary Syndromes (HE-MACS) decision aid. AB - OBJECTIVES: Several decision aids can 'rule in' and 'rule out' acute coronary syndromes (ACS) in the Emergency Department (ED) but all require measurement of blood biomarkers. A decision aid that does not require biomarker measurement could enhance risk stratification at triage and could be used in the prehospital environment. We aimed to derive and validate the History and ECG-only Manchester ACS (HE-MACS) decision aid using only the history, physical examination and ECG. METHODS: We undertook secondary analyses in three prospective diagnostic accuracy studies that included patients presenting to the ED with suspected cardiac chest pain. Clinicians recorded clinical features at the time of arrival using a bespoke form. Patients underwent serial troponin sampling and 30-day follow-up for the primary outcome of ACS. The model was derived by logistic regression in one cohort and validated in two similar prospective studies. RESULTS: The HE-MACS model was derived in 796 patients and validated in cohorts of 474 and 659 patients. HE-MACS incorporated age, sex, systolic blood pressure plus five historical variables to stratify patients into four risk groups. On validation, 5.5 and 12.1% (pooled total 9.4%) patients were identified as 'very low risk' (potential immediate rule out) with a pooled sensitivity of 99.5% (95% confidence interval: 97.1-100.0%). CONCLUSION: Using only the patient's history and ECG, HE MACS could 'rule out' ACS in 9.4% of patients while effectively risk stratifying remaining patients. This is a very promising tool for triage in both the prehospital environment and ED. Its impact should be prospectively evaluated in those settings.

PMID- 30289777 TI - Clinical Overview and Considerations for the Management of Opioid-induced Constipation in Patients with Chronic Noncancer Pain. AB - OBJECTIVES: Opioid analgesics may be associated with chronic adverse effects, such as opioid-induced constipation (OIC). Available and emerging prescription medications for OIC in patients with chronic noncancer pain are described, including concerns and challenges associated with OIC management. METHODS: Narrative review. RESULTS: Opioid-induced constipation is characterized by a change in bowel habits and defecation patterns that occurs when initiating opioid therapy and is associated with reduced bowel frequency, straining, sensation of incomplete evacuation, and/or patient distress related to bowel habits. Prescription medications are indicated when OIC persists despite conservative approaches (eg, increased fiber and fluid intake, exercise, over-the-counter laxatives and stool softeners). Phase 3 studies have demonstrated the efficacy of peripherally acting u-opioid receptor antagonists (PAMORA; methylnaltrexone, naloxegol, naldemedine), and a chloride channel activator (lubiprostone) for improving OIC in patients with chronic noncancer pain. While head-to-head studies are lacking, a meta-analysis demonstrated that MU -opioid receptor antagonists were more effective than placebo for the treatment of OIC. The most common adverse effects associated with prescription medications for OIC are gastrointestinal-related (eg, nausea, diarrhea, abdominal pain or distention), with most being mild or moderate in severity. Therapy currently in development for OIC includes the PAMORA axelopran. DISCUSSION: Health care providers should be aware of this complication in patients receiving opioids and should monitor and address constipation-related symptoms to optimize pain management and improve patient quality of life.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30289776 TI - Effect of hemorheological parameters on myocardial injury after primary or elective percutaneous coronary intervention. AB - BACKGROUND: Abnormal blood viscosity favors atherosclerosis owing to endothelial dysfunction and changes in shear stress. Its effect on coronary microvasculature during percutaneous coronary intervention (PCI) is still unknown. We aimed to investigate the role of hemorheological parameters in the incidence of microvascular obstruction (MVO) and the periprocedural necrosis after primary or elective PCI, and secondarily, we evaluated their prognostic significance. MATERIALS AND METHODS: We enrolled 25 patients with ST-elevation myocardial infarction (STEMI), 30 patients with non-ST-elevation myocardial infarction (NSTEMI), and 30 patients with stable angina (SA) undergoing PCI. MVO in patients with STEMI and periprocedural necrosis in patients with NSTEMI and those with SA were assessed using angiographic/electrocardiographic and laboratory methods, respectively. Hemorheological profile included blood viscosity (eta) at shear rates 200 s and 1 s, the erythrocyte aggregation index (eta1/eta200), and plasma viscosity. Major adverse cardiovascular events occurrence was evaluated at follow up. RESULTS: Patients with STEMI experiencing angiographic MVO (28%) had higher eta200 (5.42+/-1.28 vs. 3.98+/-1.22 mPa[BULLET OPERATOR]s; P=0.015). Similarly, patients with STEMI experiencing electrocardiographic MVO (56%) had higher eta200 (4.58+/-0.36 vs. 3.94+/-0.19 mPa[BULLET OPERATOR]s; P<0.001). Among patients with SA and patients with NSTEMI, those experiencing periprocedural necrosis (23.3%) had higher eta200 (5.30+/-0.86 vs. 4.37+/-0.88 mPa[BULLET OPERATOR]s; P=0.001), eta1 (19.52+/-9.62 vs. 13.29+/-7.65 mPa[BULLET OPERATOR]s; P=0.015) and eta1/eta200 values (3.64+/-1.50 vs. 2.72+/-0.92; P=0.007). These significant differences were maintained after adjustment for age, sex, and cardiovascular risk factors. At follow-up (30+/-6 months), 25 (29.4%) patients presented major adverse cardiovascular events, and they had higher eta200 (5.18+/-1.00 vs. 4.25+/ 1.01 mPa[BULLET OPERATOR]s; P<0.001). CONCLUSION: In patients undergoing either urgent or elective PCI, hemorheological parameters might contribute to myocardial injury and, if furtherly confirmed, to an unfavorable outcome.

PMID- 30289788 TI - Comparing the International Classification of Functioning, Disability, and Health Core Sets for Hearing Loss and Otorhinolaryngology/Audiology Intake Documentation at Mayo Clinic. AB - OBJECTIVES: The International Classification of Functioning, Disability, and Health (ICF) Core Sets for Hearing Loss (CSHL) consists of short lists of categories from the entire ICF classification that are thought to be the most relevant for describing the functioning of persons with hearing loss. A comprehensive intake that covers all factors included in the ICF CSHL holds the promise of developing a tailored treatment plan that fully complements the patient's needs. The Comprehensive CSHL contains 117 categories and serves as a guide for multiprofessional, comprehensive assessment. The Brief CSHL includes 27 of the 117 categories and represents the minimal spectrum of functioning of persons with HL for single-discipline encounters or clinical trials. The authors first sought to benchmark the extent to which Audiologist (AUD) and Otorhinolaryngologist (ORL) discipline-specific intake documentation, as well as Mayo Clinic's multidisciplinary intake documentation, captures ICF CSHL categories. DESIGN: A retrospective study design including 168 patient records from the Department of Otorhinolaryngology/Audiology of Mayo Clinic in Jacksonville, Florida. Anonymized intake documentation forms and reports were selected from patient records filed between January 2016 and May 2017. Data were extracted from the intake documentation forms and reports and linked to ICF categories using pre-established linking rules. "Overlap," defined as the percentage of ICF CSHL categories represented in the intake documentation, was calculated across document types. In addition, extra non-ICF CSHL categories (ICF categories that are not part of the CSHL) and extra constructs (constructs that are not part of the ICF classification) found in the patient records were described. RESULTS: The total overlap of multidisciplinary intake documentation with ICF CSHL categories was 100% for the Brief CSHL and 50% for the Comprehensive CSHL. Brief CSHL overlap for discipline-specific documentation fell short at 70% for both AUD and ORL. Important extra non-ICF CSHL categories were identified and included "sleep function" and "motor-related functions and activities," which mostly were reported in relation to tinnitus and vestibular disorders. CONCLUSION: The multidisciplinary intake documentation of Mayo Clinic showed 100% overlap with the Brief CSHL, while important areas of nonoverlap were identified in AUD- and ORL-specific reports. The ICF CSHL provides a framework for describing each hearing-impaired individual's unique capabilities and needs in ways currently not documented by audiological and otological evaluations, potentially setting the stage for more effective individualized patient care. Efforts to further validate the ICF CSHL may require the involvement of multidisciplinary institutions with commonly shared electronic health records to adequately capture the breath of the ICF CSHL.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

AB - Vesicular hand dermatitis is a type of eczema involving the fingers, hands, and sometimes the feet. It is common in primary care, requiring prompt treatment to prevent chronicity. The cause is often unknown, making the condition challenging to treat. Management consists of avoiding irritants and using emollients and topical corticosteroids. PMID- 30289790 TI - Comparisons of Health Promoting Behavior, Depression, and Life Satisfaction Between Older Adults in Rural Areas in South Korea Living in Group Homes and at Home. AB - BACKGROUND: In South Korea, population aging is advancing at a more rapid rate in rural areas than urban areas, leading to a particularly high percentage of rural dwelling older adults. PURPOSE: The aim of this study was to examine and compare health promoting behaviors, depression, and life satisfaction between rural dwelling older adults who live, respectively, in group homes and at home. METHODS: A cross-sectional descriptive study design was employed. Study participants included 160 older adults aged 65 years and older who were living in group homes (n = 80) and at home (n = 80) in Gyeonggi province, South Korea. The Health Promotion Lifestyle Profile-II was used to examine health promoting behaviors, the Korean Geriatric Depression Screening Scale was used to examine depression, and the Life Satisfaction Index was used to examine life satisfaction. Data were analyzed using SPSS Version 21.0. RESULTS: The data showed significant differences between the two groups in terms of health promoting behaviors (t = -9.035, p < .001), depression (t = 20.861, p < .001), and life satisfaction (t = -12.153, p < .001). CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The mean scores for health promotion behaviors and life satisfaction were higher, and the mean score for depression was lower in the group-home group than the at-home group. The findings from this study may be employed as basic data for establishing residence-appropriate nursing intervention protocols for older adults living in rural areas. PMID- 30289791 TI - DOCUMENTATION OF A NEW CHOROIDAL NEVUS. AB - PURPOSE: To describe the occurrence of an acquired choroidal nevus in a 73-year old white man. METHODS: Case report. RESULTS: A 73-year-old white man was referred for an evaluation and treatment of macular changes in his left eye consistent with pachychoroid neovasculopathy. Baseline funduscopic examination and color fundus photographs showed two small peripheral choroidal nevi in the right eye and a single small choroidal nevus in the far temporal macula of the left eye. Treatment with intravitreal aflibercept was initiated in the left eye on a treat-and-extend dosing regimen. Approximately 1 year later, a new pigmented choroidal lesion was detected in the left macula in an area where previous high resolution color fundus photographs had shown no abnormal pigmentation. Swept source optical coherence tomography of the new pigmented lesion showed flat hyperreflectivity within the inner choroid consistent with a small choroidal nevus. The patient was referred to his internist who found no evidence of an occult malignancy. Over the course of more than 4 additional years of continuous follow-up, the new choroidal nevus remained stable, no new fundus abnormalities were detected in either eye, and the patient remained medically stable. CONCLUSION: To the best of our knowledge, this is the first documented case of a new choroidal nevus. Multimodal imaging performed before lesion detection and over the ensuing 4 years showed its stability, thus allowing for the conclusion that it was a benign choroidal nevus rather than a neoplastic or paraneoplastic process. PMID- 30289792 TI - Recurrent Superior Oblique Myokymia Treated by Distal Tendon Extirpation. AB - BACKGROUND: We describe successful surgical treatment of superior oblique myokymia, which had recurred after superior oblique tenectomy. METHODS: Single case report. RESULTS: The distal stump of the superior oblique tendon was extirpated by stripping it from the globe. The ipsilateral superior rectus muscle also was recessed, to correct a hypertropia that had resulted from the original superior oblique tenectomy. CONCLUSIONS: Complete removal of the distal superior oblique muscle tendon provided definitive relief of superior oblique myokymia. Superior rectus muscle recession, combined with previous inferior oblique myectomy, compensated effectively for loss of superior oblique function.

PMID- 30289794 TI - Implementation of a Hip Fracture Care Pathway Using Lean Six Sigma Methodology in a Level I Trauma Center. AB - INTRODUCTION: The application of Lean Six Sigma (LSS) methodology with regard to hip fracture care remains unexamined. The aim of this study is to illustrate the application of LSS principles in the implementation of a hip fracture integrated care pathway (ICP). METHODS: A multidisciplinary team at a level I trauma center formed a hip fracture ICP using LSS principles. An ICP aimed toward decreasing time to surgery to <48 hours was implemented in April 2012. RESULTS: A total of 505 hip fracture patients met inclusion criteria. A total of 221 patients entered the preimplementation cohort, and 284 were incorporated in the postimplementation cohort. The percentage of patients who received surgical fixation beyond 48 hours significantly decreased (9.50% versus 4.23%; P = 0.01). Significantly more complications were detected in the postimplementation cohort (62.44% versus 80.10%; P < 0.01). The postimplementation cohort showed a significantly shorter length of stay (P = 0.02) and decreased hospital cost (P = 0.016). CONCLUSION: Our findings suggest that using LSS methods in an ICP at our institution resulted in markedly greater percentage of patients receiving surgical care within 48 hours, greater detection of complication, and reduced resource consumption. PMID- 30289795 TI - Prescription Opioid Type and the Likelihood of Prolonged Opioid Use After Orthopaedic Surgery. AB - INTRODUCTION: A common belief is that some narcotic medications have a higher association with prolonged use. We assessed whether the initial opiate type prescribed to postoperative, opiate-naive orthopaedic trauma patients was associated with prolonged opioid use. METHODS: We studied 17,961 adult, opiate naive patients treated for a surgical musculoskeletal injury. Discharge prescription in morphine milligram equivalents (MMEs, a standardized dosing unit that allows for comparison across opioid types) was calculated. Opioid prescribing beyond 90 days after injury was defined as prolonged use. RESULTS: Initial analysis demonstrated a higher likelihood of prolonged use for patients discharged on hydromorphone or morphine versus hydrocodone. However, when we adjusted for discharge MME, only opioid quantity was predictive of prolonged use (P < 0.001). In addition, discharge MME was associated with opioid type (P < 0.01). DISCUSSION: Persistent opiate use was associated with discharge opioid quantity, not the opioid type. These results highlight the importance of calculating equivalence doses when selecting opioid types and considering amount of narcotics prescribed. LEVEL OF EVIDENCE: Level III. PMID- 30289796 TI - Robotic-assisted Medial Unicompartmental Knee Arthroplasty: Options and Outcomes. AB - Medial unicompartmental knee arthroplasty (UKA) has several benefits over total knee arthroplasty for the surgical treatment of isolated medial compartmental arthritis in the knee, including reduced surgical risk and postoperative morbidity, rapid recovery, more normal kinematics, greater patient satisfaction, and shorter hospitalization. Nonetheless, there is substantial concern about the higher revision rates and lower survivorship in UKA compared to those in total knee arthroplasty. Robotic assistance has been advanced to improve the precision of bone preparation, component alignment, and quantified ligament balance in UKA, with the ultimate goal of improving kinematics and implant survivorship. Two currently available semiautonomous robotic platforms have demonstrated improved accuracy, and emerging short-term follow-up has demonstrated satisfactory functional outcomes. Further studies will be needed to determine if these technologies indeed have a meaningful impact on patient outcomes and survivorship in the mid- to long term. PMID- 30289797 TI - Total Hip Arthroplasty for Posttraumatic Conditions. AB - Posttraumatic arthritis accounts for a notable share of secondary osteoarthritis about the hip joint. Compared with total hip arthroplasty for primary osteoarthritis or inflammatory arthritis, total hip arthroplasty for posttraumatic arthritis offers greater technical challenges because of bone deformities and retained implants. Careful preoperative evaluation is necessary to prepare the approach, hardware removal strategy, and implants necessary to address bone deficiencies. Although arthroplasty is a highly successful procedure for posttraumatic arthritis, the results are less favorable than surgery for primary osteoarthritis. It is associated with a higher incidence of intraoperative and postoperative complications, including periprosthetic fractures, infection, instability, and decreased survivorship. PMID- 30289798 TI - Incidence and Risk Factors Associated with Venous Thromboembolism After Orthopaedic Below-knee Surgery. AB - INTRODUCTION: Among patients undergoing below-knee orthopaedic surgery, no consensus exists regarding the need for or type of postoperative prophylaxis to prevent venous thromboembolic (VTE) events. The purpose of this study was to assess the incidence and risk factors associated with symptomatic VTE among orthopaedic patients undergoing below-knee surgery who were subject to different types of pharmacologic thromboprophylactic strategies. METHODS: A total of 20,043 adult patients who underwent surgery for a below-knee orthopaedic condition between August 2005 and August 2015 were identified. Retrospective chart review recorded patient demographics, comorbid data, and anatomic location of any procedures performed. Multivariable logistic regression analysis was used to determine factors associated with postoperative development of symptomatic VTE among patients receiving various thromboprophylactic regimens. RESULTS: The incidence of symptomatic VTE in patients who underwent below-knee surgery was 2.5% (492/20,043). For patients who did not receive thromboprophylaxis, the incidence was 1.5% (134/9,127 patients). In this group, risk factors for developing VTE were male sex; nonwhite race; surgery performed below the knee but above the ankle; combination procedures of the forefoot/midfoot, hindfoot/ankle, and/or lower leg; history of VTE; and Charlson Comorbidity Index score greater than 2. Among patients who received an antiplatelet agent, the VTE incidence was 1.7% (33/1,992 patients). The incidence of VTE among patients who received an oral or injectable anticoagulant was 3.6% (325/8,924 patients). In this group, risk factors for developing VTE were male sex; surgery performed below the knee but above the ankle; combination procedures of the forefoot/midfoot, hindfoot/ankle, and/or lower leg; and history of VTE. CONCLUSION: Allowing for different types of thromboprophylactic strategies, the results of this study demonstrate a higher rate of symptomatic thromboembolic disease compared with previously reported <1% VTE incidence rates among orthopaedic patients undergoing below-knee surgery. Certain patients are at higher risk for thromboembolic disease after below-knee orthopaedic surgery. This risk was not found to be lowered by thromboprophylaxis as performed in patients in this database. Future research should be directed at determining what the best thromboprophylactic strategies are for lowering this risk. LEVEL OF EVIDENCE: Therapeutic study level III. PMID- 30289799 TI - Specialty Focus: Lower Extremity, Hip and Knee Issue. PMID- 30289800 TI - Neurodevelopmental outcomes in HIV-infected and uninfected African children. AB - OBJECTIVE: HIV infection is associated with cognitive impairments, but outcomes are poorly explored in children starting antiretroviral therapy (ART) early or in those exposed but uninfected. DESIGN: Nested cross-sectional evaluation of the neurocognitive and behavioural outcomes of HIV-infected, HIV-exposed uninfected (HEU) and HIV-unexposed (HUU) Cameroonian children at age 4-9 years prospectively followed. METHODS: Cognitive development was assessed in 127 HIV-infected, 101 HEU, 110 HUU children using the KABC-II, neurologic dysfunction using the Touwen examination and behavioural difficulties using the Strength and Difficulties Questionnaire (SDQ). Analyses were adjusted for children age, sex and primary language. Contextual factors were included in a second step to assess their effects on outcomes. RESULTS: All HIV-infected children were treated before 12 months. There was a negative linear gradient in KABC-II scores from HUU children to HEU and HIV-infected children [gradient: -6.0 (-7.7; -4.3) for nonverbal index, NVI, and -8.8 (-10.7; -6.8) for mental processing index, MPI]. After adjusting for contextual factors, scores of HEU children were not significantly different from those of HUU children (all P > 0.1) and differences between HIV uninfected and HUU children reduced [NVI: from -11.9 (-15.3; -8.5) to -3.4 (-6.8; -0.01), MPI: from -17.6 (-21.3; -13.8) to -5.5 (-9.3; -1.7)]. Compared with uninfected children, HIV-infected children had more neurological dysfunctions and higher SDQ scores (P = 0.002). CONCLUSION: Despite early ART, perinatal-HIV infection is associated with poorer neurocognitive scores and increased behavioural difficulties during childhood. Contextual factors play an important role in this association, which emphasizes the need for early nutritional and developmental interventions targeting both HIV-affected infants and their relatives. PMID- 30289801 TI - HIV messaging on Twitter: an analysis of current practice and data-driven recommendations. AB - OBJECTIVES: Social media messages have been increasingly used in health campaigns about prevention, testing, and treatment of HIV. We identified factors leading to the retransmission of messages from expert social media accounts to create data driven recommendations for online HIV messaging. DESIGN AND METHODS: We sampled 20 201 HIV-related tweets (posted between 2010 and 2017) from 37 HIV experts. Potential predictors of retransmission were identified based on prior literature and machine learning methods, and were subsequently analyzed using multilevel negative binomial models. RESULTS: Fear-related language, longer messages, and including images (e.g. photos, gif, or videos) were the strongest predictors of retweet counts. These findings were similar for messages authored by HIV experts, and also messages retransmitted by experts, but created by nonexperts (e.g. celebrities or politicians). CONCLUSIONS: Fear appeals affect how much HIV messages spread on Twitter, as do structural characteristics, like the length of the tweet and inclusion of images. A set of five data-driven recommendations for increasing message spread is derived and discussed in the context of current centers for disease control and prevention social media guidelines. PMID- 30289802 TI - Randomized controlled trial of a community-based intervention on HIV and nutritional outcomes at 6 months among women living with HIV/AIDS in rural India. AB - OBJECTIVE: To assess the impact of nurse-led Asha (Accredited Social Health Activist)-support behavioral and nutritional intervention among women living with HIV/AIDS (WLH/A) in rural India. DESIGN: Cluster randomized controlled trial. METHODS: Sixteen Primary Health Centers serving WLH/A in Andhra Pradesh were grouped into four regional clusters that were randomly allocated into one of four arms. All four groups included Asha-support and consisted of: Asha-support only (control group); nutrition education; nutrition supplementation; and the combination of supplementation and education. Differences between baseline and 6 month follow-up for key physiological outcomes (BMI, CD4 cell count) were analyzed using factorial mixed models that accounted for geographic clustering. RESULTS: At 6 months, all groups improved CD4 cell count: Asha only [mean difference score (D) = 343.97, standard deviation (SD) = 106.94], nutrition education (D = 356.15, SD = 0.69), nutrition supplement (D = 469.66, SD = 116.0), and nutrition supplement and education (D = 530.82, SD = 128.56). In multivariable models, Asha-support and nutrition, and Asha-support and nutrition supplement interventions demonstrated independent significant improvements in CD4 cell count; the interaction term was significant [estimate = 529.9; 95% confidence interval (CI) 512.0, 547.8; P = 0.006]. BMI also increased for all groups: Asha only (D = 0.95, SD = 0.82), Asha and nutrition education (D = 1.28, SD = 0.53), Asha and nutrition supplement (D = 2.38, SD = 0.60), nutrition supplement, and nutrition supplement and education (D = 2.72, SD = 0.84). Nutrition supplementation and nutrition education demonstrated independent effects on BMI; the interaction term was not significant (estimate = 0.27; 95% CI = 2.5, 2.7; P = 0.80). CONCLUSION: Interventions supported by community workers were efficacious at improving physiological outcomes and may be beneficial at meeting critical healthcare needs of vulnerable WLH/A in India. PMID- 30289803 TI - Sex differences in HIV-associated cognitive impairment: an observational cohort study. AB - OBJECTIVE: We determined whether there are sex differences in the prevalence and profile of HIV-associated neurocognitive impairment, and whether sex moderates the effect of HIV-serostatus on neurocognitive impairment among HIV+ and HIV- individuals. Secondarily, we assessed whether differences were explained by greater biopsychosocial risk factors in HIV+ women. DESIGN: Observational cohort study. METHODS: Analyses included 1,361 HIV+ (204 women) and 702 HIV- (214 women) (ages = 18-79) participants from the UCSD HIV Neurobehavioral Research Program. Demographically-corrected standardized T-scores from 15 neuropsychological tests were used to calculate domain-specific and global deficit scores (GDS). GDS>=0.5 defined neurocognitive impairment. Biopsychosocial risk factors included low education, low reading level (education quality), lifetime substance use disorders, depressed mood (clinically-significant depressive symptoms and/or current major depressive disorder), and a cumulative syndemic count (sum of biopsychosocial risk factors, range = 0-4). Race-stratified analyses were conducted. Analyses were adjusted for relevant demographic and clinical factors. RESULTS: HIV-associated neurocognitive impairment was more prevalent in women versus men; however, the difference was eliminated after adjustment for reading level. In sex-stratified logistic regressions, the association between HIV seropositivity and higher likelihood of neurocognitive impairment was stronger in women versus men; however, the association was attenuated in women, but not men, after adjusting for reading level. These results in the overall sample were specific to blacks. Sex differences in the profile of HIV-associated neurocognitive impairment varied by race. CONCLUSIONS: Women, particularly black women, were most at-risk for HIV-associated neurocognitive impairment. Higher rates of HIV-associated neurocognitive impairment in women versus men may reflect differences in educational quality.

AB - OBJECTIVE: Universal eligibility for lifelong antiretroviral therapy (ART) for pregnant and breastfeeding women ('Option B+') has been widely adopted, but concerns remain. We tested the hypothesis that the change from CD4-guided ART eligibility ('Option A'), to Option B+, would improve maternal ART uptake and retention. DESIGN: A stepped-wedge evaluation at 12 health facilities in eSwatini. METHODS: Primary outcome was maternal retention: proportion of women attending clinic within 56 days of delivery (antenatal retention) and clinic attendance within 84 days of 6-months postpartum (postnatal retention). Generalized estimating equations examined impact of Option B+ vs. Option A. RESULTS: Between 19 August 2013 and 29 August 2014, 2347 HIV-positive women, 55% (n = 1296) Option A, 45%, (n = 1051) Option B+ were included. ART initiation was observed in 36% (n = 469) of Option A women vs. 94% (n = 983) under Option B+ (P < 0.001). Overall 39% (n = 912) were retained from first ANC visit through 6 months postpartum. Retention was higher under Option B+ (53%, n = 559) vs. Option A (24%, n = 353) with variation by site and study month. Adjusting for age, gestational age, previous HIV diagnosis, and CD4, Option B+ women were significantly more likely to be retained antenatally (aRR 1.32; 95% CI 1.18-1.49; P < 0.001) and postnatally (aRR 2.11; 95% CI 1.79-2.49) compared with Option A. Restricted to women initiating ART, retention was lower under Option B+ (57%, n = 558) vs. Option A (66%, n = 309; aRR, 0.82; 95% CI 0.70-0.95; P < 0.0001). CONCLUSION: Compared with CD4-guided ART eligibility, universal ART resulted in substantial increases in pregnant women initiating ART and retained in care through 6 months postpartum. PMID- 30289805 TI - Phase I clinical trial of an intranodally administered mRNA-based therapeutic vaccine against HIV-1 infection. AB - OBJECTIVE: The efficacy of therapeutic vaccines against HIV-1 infection has been modest. New inerts to redirect responses to vulnerable sites are urgently needed to improve these results. DESIGN: We performed the first-in-human clinical trial with naked mRNA (iHIVARNA) combining a dendritic cell activation strategy (TriMix:CD40L+CD70+caTLR4 RNA) with a novel HIV immunogen sequences (HTI immunogen). METHODS: A dose escalation, phase I clinical trial was performed in 21 chronic HIV-1-infected patients under ART who received three intranodal doses of mRNA (weeks 0, 2 and 4) as follow: TriMix-100 g, TriMix-300 g, TriMix-300 g with HTI-300 g, TriMix-300 g with HTI-600 g, TriMix-300 g with HTI-900 g. Primary end-point was safety and secondary-exploratory end-points were immunogenicity, changes in viral reservoir and transcriptome. RESULTS: Overall, the vaccine was secure and well tolerated. There were 31 grade 1/2 and 1 grade 3 adverse events, mostly unrelated to the vaccination. Patients who received the highest dose showed a moderate increase in T-cell responses spanning HTI sequence at week 8. In addition, the proportion of responders receiving any dose of HTI increased from 31% at w0 to 80% postvaccination. The intervention had no impact on caHIV DNA levels, however, caHIV-RNA expression and usVL were transiently increased at weeks 5 and 6 in the highest dose of iHIVARNA, and these changes were positively correlated with HIV-1-specific-induced immune responses. CONCLUSION: This phase I dose-escalating trial showed that iHIVARNA administration was safe and well tolerated, induced moderate HIV-specific T-cell responses and transiently increased different viral replication readouts. These data support further exploration of iHIVARNA in a phase II study. CLINICALTRIALS. GOV IDENTIFIER: NCT02413645. PMID- 30289807 TI - Metabolic pathway activation distinguishes transcriptional signatures of CD8+ T cells from HIV-1 elite controllers. AB - OBJECTIVE: Elite controllers, defined as persons maintaining undetectable levels of HIV-1 replication in the absence of antiretroviral therapy, represent living evidence that sustained, natural control of HIV-1 is possible, at least in relatively rare instances. Understanding the complex immunologic and virologic characteristics of these specific patients holds promise for inducing drug-free control of HIV-1 in broader populations of HIV-1 infected patients. DESIGN: We used an unbiased transcriptional profiling approach to characterize CD8 T cells, the strongest correlate of HIV-1 immune control identified thus far, in a large cohort of elite controllers (n = 51); highly active antiretrovial therapy (HAART) treated patients (n = 32) and HIV-1 negative (n = 10) served as reference cohorts. METHODS: We isolated mRNA from total CD8 T cells isolated from peripheral blood mononuclear cell (PBMC) of each individual followed by microarray analysis of the transcriptional signatures. RESULTS: We observed profound transcriptional differences [590 transcripts, false discovery rate (FDR) adjusted P < 0.05] between elite controller and HAART-treated patients. Interestingly, metabolic and signalling pathways governed by mammalian target of rapamycin (mTOR) and eIF2, known for their key roles in regulating cellular growth, proliferation and metabolism, were among the top functions enriched in the differentially expressed genes, suggesting a therapeutically actionable target as a distinguishing feature of spontaneous HIV-1 immune control. A subsequent bootstrapping approach distinguished five different subgroups of elite controller, each characterized by distinct transcriptional signatures. However, despite this marked heterogeneity, differential regulation of mTOR and eIF2 signalling remained the dominant functional pathway in three of these elite controller subgroups. CONCLUSION: These studies suggest that mTOR and eIF2 signalling may play a remarkably universal role for regulating CD8 T-cell function from elite controllers. PMID- 30289806 TI - Are European HIV cohort data within EuroCoord representative of the diagnosed HIV population? AB - OBJECTIVE: HIV cohorts are an important source of clinical data for informing public health policies and programmes. However, the generalizability of cohort findings to the wider population of people diagnosed with HIV in each country remains unclear. In this work, we assessed the representativeness of six large national HIV cohorts within Europe. DESIGN AND METHODS: Individual-level cohort data were provided from national cohorts in France, Germany, Greece, Italy, Spain and the United Kingdom. Analysis focused on new HIV diagnoses reported to The European Surveillance System (TESSy) during three time periods (2000-2004, 2005 2009 and 2010-2013), to allow for temporal changes. Cohort and TESSy records were matched and compared by age, sex, transmission mode, region of origin and CD4 cell count at diagnosis. The probability of being included in each cohort given demographic characteristics was estimated and used to generate weights inversely proportional to the probability of being included. RESULTS: Participating cohorts were generally representative of the national HIV-diagnosed population submitted to TESSy. However, people who inject drugs, those born in a country other than that reporting the data, those with low CD4 cell counts at diagnosis, and those more than 55 years were generally underrepresented in the cohorts examined. CONCLUSION: These European cohorts capture a representative sample of the HIV diagnosed populations in each country; however some groups may be underrepresented. PMID- 30289808 TI - Inhibitory natural killer cell receptor KIR3DL1 with its ligand Bw4 constraints HIV-1 disease among South Indians. AB - OBJECTIVE: To investigate the role of genotypic and phenotypic characteristics of killer cell immunoglobulin-like receptors (KIRs) and their human leukocyte antigen (HLA) class-1 ligands in HIV-1 disease progression. STUDY DESIGN AND METHODS: This is a nested case-control study including 347 HIV seropositive (HIV 1) individuals from South India constituting 45 long-term nonprogressors (LTNPs) and 302 disease progressors. KIR genotyping was performed by multiplex sequence specific primer-directed PCR (SSP-PCR). Phenotypic expressions of KIR3DL1/S1 was studied using multiparametric flow cytometry assay. HLA-Bw4 and Bw6 epitopes were determined by ARMS-PCR. HLA-Bw4, HLA-Bw4, HLA-C1, HLA-C2, and HLA-Aw4 were genotyped using SSP-PCR. Serum levels of IFN-gamma was quantified using ELISA method. RESULTS: Overall, 37 different KIR genotypes were observed and the distribution of genotypes with AB-AB (OR = 2.2, P = 0.033) constellations showed significant increase among LTNPs. The frequencies of 3DL1-2DL3-2DL5 (OR = 2.2, Pc = 0.031), 3DL1-Bw4/Aw4 (OR = 2.49, Pc = 0.019), homozygous Bw4 (OR = 2.422, Pc = 0.011) were observed higher in LTNPs and 2DS1-2DS2-2DS3 (OR = 0.475, Pc = 0.03), homozygous Bw6 (OR = 0.413, Pc = 0.011) were higher in the disease progressors. Flow cytometry assay showed the increased expression and maintenance of 3DL1/S1NK cells in LTNPs (P = 0.0001). Further the expansion of 3DS1NK cells was higher than 3DL1NK cells in the heterozygous 3DL1/S1 LTNPs (P = 0.001). CONCLUSION: The inhibitory receptor 3DL1 with Bw4 and its A-haplotype defining KIR genes (2DL3/L5) confers protection against HIV-1 disease progression. An increased expression and maintenance of 3DL1/S1 natural killer cells may contribute to the efficient activation of the natural killer cells and subsequent long-term nonprogression (LTNPn) to the disease. PMID- 30289810 TI - Increase in HSV shedding at initiation of antiretroviral therapy and decrease in shedding over time on antiretroviral therapy in HIV and HSV-2 infected persons. AB - OBJECTIVES: HIV-infected persons with chronic herpesvirus infections may experience paradoxical worsening after initiation of antiretroviral therapy (ART), but the impact of longer term ART is unclear. We evaluated the relationships between genital herpes simplex virus (HSV) shedding and ART initiation and time on therapy in HIV and HSV-2-infected persons. DESIGN: Prospective observational study. METHODS: Rates of HSV shedding in 45 HIV and HSV 2-infected persons on or off ART were prospectively followed over up to three, noncontiguous, 60-day periods, during which participants performed daily genital swabs for HSV detection by real-time HSV DNA PCR and reported symptoms. Initiation or discontinuation of ART was at the discretion of participants' healthcare providers. RESULTS: In all, 6425 daily genital swabs were obtained from 45 persons (38 men and seven women) during 105 swabbing sessions. During the three sessions, 67, 74, and 92% of persons were on ART. HSV was detected on 26.5% of days in men and 22.3% of days in women. The overall rates of genital HSV shedding were 19.4% of days in persons not on ART, 30.2% in persons within 90 days of ART initiation, and 23.3% in persons on ART for longer than 90 days. After initiation of ART, HSV shedding decreased by 2% per month, or 23% per year (RR 0.98/month on ART; P = 0.0003 in adjusted analysis). This finding was consistent after including consideration of HIV viral load and CD4 cell count. CONCLUSIONS: HSV shedding increased significantly shortly after ART initiation, but decreased with time on prolonged ART. PMID- 30289809 TI - Pain in people living with HIV and its association with healthcare resource use, well being and functional status. AB - OBJECTIVE: We describe the prevalence of pain and its associations with healthcare resource utilization and quality-of-life. DESIGN: The POPPY Study recruited three cohorts: older people living with HIV (PLWH; >=50 years, n = 699), younger demographically/lifestyle similar PLWH (less than 50 years, n = 374) and older demographically/lifestyle similar HIV-negative (>=50 years, n = 304) people from April 2013 to February 2016. METHODS: Current pain and pain related healthcare use was collected via a self-reported questionnaire. Logistic regression assessed between-group differences in the prevalence of pain in the past month and current pain after controlling for potential confounders. Associations between current pain and healthcare resource use, reported joint problems, depressive symptoms, quality-of-life and functional status were assessed in PLWH using Mann-Whitney U and chi-squared tests. RESULTS: Pain in the past month was reported by 473 out of 676 (70.0%) older PLWH, 224 out of 357 (62.7%) younger PLWH and 188 out of 295 (63.7%) older HIV-negative controls (P = 0.03), with current pain reported in 330 (48.8%), 134 (37.5%) and 116 (39.3%), respectively (P = 0.0007). Older PLWH were more likely to experience current pain, even after adjustment for confounders. Of those with pain in the past month, 56 out of 412 (13.6%) had missed days of work or study due to pain, and 520 (59%) had seen a doctor about their pain. PLWH experiencing current pain had more depressive symptoms, poorer quality-of-life on all domains and greater functional impairment, regardless of age group. CONCLUSION: Even in the effective antiretroviral therapy era, pain remains common in PLWH and has a major impact on quality-of-life and associated healthcare and societal costs. Interventions are required to assist clinicians and PLWH to proactively manage pain. PMID- 30289811 TI - Women, incarceration and HIV: a systematic review of HIV treatment access, continuity of care and health outcomes across incarceration trajectories. AB - OBJECTIVE: The aim of this study was to systematically review the literature on gendered implications of incarceration for HIV outcomes and engagement in care for women living with HIV (WLWH). DESIGN: We systematically searched seven bibliographic databases, for peer-reviewed English-language studies, published between 2007 and 2017 reporting on incarceration, women (transgender inclusive) and HIV. METHODS: Articles were included for evaluation if they reported outcomes for at least one of three measures of interest: viral load, antiretroviral therapy (ART) adherence or engagement in care among WLWH along incarceration trajectories. RESULTS: Out of 1119 studies, 24 (2%) met the inclusion criteria. Of these 24 studies, the majority (n = 23) were conducted in the USA, 19 included samples of women and men and seven studies were transgender inclusive. Our review did not reveal clear sex differences in HIV outcomes during periods of incarceration; however, studies reporting postincarceration outcomes demonstrated significant sex disparities in all three outcomes of interest. Following incarceration, women were less likely to be virally suppressed, less likely to achieve optimal ART adherence and less likely to be engaged in care. CONCLUSION: Despite growing numbers of incarcerated WLWH globally, there is a substantial gap in research examining the impact of incarceration on HIV outcomes for WLWH. Significant sex disparities in HIV outcomes and engagement in care exist along incarceration trajectories for WLWH, especially postincarceration. For improved health outcomes, research is needed to examine the experiences of WLWH throughout incarceration trajectories to develop interventions tailored to the specific needs of WLWH both during and following incarceration. PMID- 30289812 TI - Predicting diabetes risk among HIV-positive and HIV-negative women. AB - OBJECTIVE: To assess the performance of an adapted American Diabetes Association (ADA) risk score and the concise Finnish Diabetes Risk Score (FINRISC) for predicting type 2 diabetes development in women with and at risk of HIV infection. DESIGN: Longitudinal analysis of the Women's Interagency HIV Study. METHODS: The women's Interagency HIV Study is an ongoing prospective cohort study of women with and at risk for HIV infection. Women without prevalent diabetes and 3-year data on fasting blood glucose, hemoglobin A1c, self-reported diabetes medication use, and self-reported diabetes were included. ADA and FINRISC scores were computed at baseline and their ability to predict diabetes development within 3 years was assessed [sensitivity, specificity and area under the receiver operating characteristics (AUROC) curve]. RESULTS: A total of 1111 HIV-positive (median age 41, 60% African American) and 454 HIV-negative women (median age 38, 63% African-American) were included. ADA sensitivity did not differ between HIV positive (77%) and HIV-negative women (81%), while specificity was better in HIV negative women (42 vs. 49%, P = 0.006). Overall ADA discrimination was suboptimal in both HIV-positive [AUROC = 0.64 (95% CI: 0.58, 0.70)] and HIV-negative women [AUROC = 0.67 (95% CI: 0.57, 0.77)]. FINRISC sensitivity and specificity did not differ between HIV-positive (72 and 49%, respectively) and HIV-negative women (86 and 52%, respectively). Overall FINRISC discrimination was suboptimal in HIV positive [AUROC = 0.68 (95% CI: 0.62, 0.75)] and HIV-negative women [AUROC = 0.78 (95% CI: 0.66, 0.90)]. CONCLUSION: Model performance was suboptimal in women with and at risk of HIV, while greater misclassification was generally observed among HIV-positive women. HIV-specific risk factors known to contribute to diabetes risk should be explored in these models. PMID- 30289814 TI - High prevalence of echocardiographic abnormalities in older HIV-infected children taking antiretroviral therapy. AB - BACKGROUND: Antiretroviral therapy (ART) has decreased mortality so that increasing numbers of children with HIV are reaching adolescence. However, longstanding HIV infection and/or its treatment in children is associated with noninfectious complications including cardiac disease. We investigated the prevalence, spectrum and risk factors for echocardiographic abnormalities among children established on ART. METHODS: HIV-infected children aged 6-16 years, on ART at least 6 months were enrolled into a cross-sectional study from a public sector paediatric HIV clinic in Harare, Zimbabwe. A standardized examination including transthoracic echocardiography was performed. Local echocardiographic reference ranges were used to define cardiac abnormalities. Logistic regression was used to examine the association between cardiac abnormalities and risk factors. RESULTS: Of the 201participants recruited, 92 (46%) were girls and median age was 11 (IQR 9-12) years; CD4 cell count was 727 cells/MUl (IQR 473 935) and 154 (78%) had viral load less than 400 copies/ml. Echocardiographic abnormalities were found in 83 (42%); left ventricular (LV) diastolic dysfunction was the most common abnormality 45 (23%) and LV hypertrophy in 22 (11%). LV and left atrial dilatation were found in 9 (5%) and 16 (8%), respectively. Right ventricular dilatation and systolic dysfunction were found in 13 (7%) and 4 (2%), respectively, of whom 60% had concurrent left heart abnormalities. Current use of nevirapine was associated with LVH [aOR 3.14 (1.13-8.72; P = 0.03)] and hypertension was associated with LV diastolic dysfunction [aOR 3.12 (1.48-6.57; P < 0.01)]. CONCLUSION: HIV-infected children established on ART have a high burden of echocardiographic abnormalities. Right heart disease was predominantly associated with left heart abnormalities and may be part of a global cardiomyopathic process. Further studies are needed to investigate the natural history, aetiology, and pathogenesis of these abnormalities, so that appropriate monitoring and treatment strategies can be developed. PMID- 30289813 TI - Age-disparate partnerships and incident HIV infection in adolescent girls and young women in rural South Africa. AB - OBJECTIVE: Adolescent girls and young women (AGYW) have a much higher risk of HIV infection than young men of the same age. One hypothesis for this disparity is AGYW are more likely to be in sexual partnerships with older men with HIV; however, evidence has been inconclusive. DESIGN: We used longitudinal data from a randomized trial in South Africa (HPTN 068) to determined whether partner age difference is associated with incident HIV infection in AGYW. METHODS: Age difference was examined continuously and dichotomously (>=5 years). We examined inverse probability of exposure weighted survival curves and calculated time specific risk differences and risk ratios over 5.5 years of follow-up. We also used a marginal structural Cox model to estimate hazard ratios over the entire study period. RESULTS: Risk of HIV was higher in AGYW with an age-disparate partnership versus not and the risk difference was largest at later time points. At 5.5 years, AGYW with an age-disparate partnership had a 12.6% (95% confidence interval 1.9-23.3) higher risk than AGYW with no age-disparate partnerships. The weighted hazard ratio was 1.91 (95% confidence interval 1.33-2.74), an association that remained after weighting for either transactional or condomless sex, and after examining continuous age-differences. CONCLUSION: Age-disparate partnerships increased risk of HIV infection, even after accounting for transactional sex and condomless sex. The relationship between age-disparate partnerships and HIV infection may be explained by increased exposure to infection from men in a higher HIV prevalence pool rather than differences in sexual behaviour within these partnerships. PMID- 30289815 TI - Effectiveness of a multivitamin supplementation program among HIV-infected adults in Tanzania. AB - OBJECTIVE: The objective of this study was to assess the effectiveness of a routine multivitamin supplementation program for adults living with HIV in Tanzania. DESIGN: We conducted a retrospective cohort study of 67 707 adults enrolled in the Dar es Salaam HIV care and treatment program during 2004-2012. METHODS: The Dar es Salaam HIV care and treatment program intended to provide all adult patients with multivitamin supplements (vitamins B-complex, C, and E) free of charge; however, intermittent stockouts and other implementation issues did not afford universal coverage. We use Cox proportional hazard models to assess the time-varying association of multivitamin supplementation with mortality and clinical outcomes. RESULTS: The study cohort contributed 41 540 and 129 315 person-years of follow-up time to the antiretroviral therapy (ART)-naive and ART experienced analyses, respectively. Among 48 207 ART-naive adults, provision of multivitamins reduced the risk of mortality [adjusted hazard ratio (aHR): 0.69; 95% confidence interval (CI): 0.59-0.81], incident tuberculosis (TB) (aHR: 0.83; 0.76-0.91), and meeting ART eligibility criteria (aHR: 0.78; 95% CI: 0.73-0.83) after adjustment for time-varying confounding. Among 46 977 ART-experienced patients, multivitamins reduced mortality (hazard ratio: 0.86; 95% CI: 0.80 0.92), incident TB (aHR: 0.78; 95% CI: 0.73-0.84), and immunologic failure (aHR: 0.70; 95% CI: 0.67-0.73). The survival benefits associated with provision multivitamins appeared to be greatest during the first year of ART and declined over time (P value <0.001). CONCLUSION: Multivitamin supplementation appears to be a simple, effective, safe, and scalable program to improve survival, reduce incidence of TB, and improve treatment outcomes for adult HIV patients in Tanzania. PMID- 30289816 TI - Variation in antiretroviral treatment coverage and virological suppression among three HIV key populations. AB - OBJECTIVES: We assessed differences in antiretroviral treatment (ART) coverage and virological suppression across three HIV key populations, as defined by self reported HIV transmission category: sex between men, injection drug use (IDU) and heterosexual transmission. DESIGN: A multinational cohort study. METHODS: Within the EuroSIDA study, we assessed region-specific percentages of ART-coverage among those in care and virological suppression (<500 copies/ml) among those on ART, and analysed differences between transmission categories using logistic regression. RESULTS: Among 12 872 participants followed from 1 July 2014 to 30 June 2016, the percentages of ART-coverage and virological suppression varied between transmission categories, depending on geographical region (global P for interaction: P = 0.0148 for ART-coverage, P = 0.0006 for virological suppression). In Western [adjusted odds ratio (aOR) 1.41 (95% confidence interval 1.14-1.75)] and Northern Europe [aOR 1.68 (95% confidence interval 1.25-2.26)], heterosexuals were more likely to receive ART than MSM, while in Eastern Europe, there was some evidence that infection through IDU [aOR 0.60 (95% confidence interval 0.31-1.14)] or heterosexual contact [aOR 0.58 (95% confidence interval 0.30-1.10)] was associated with lower odds of receiving ART. In terms of virological suppression, people infected through IDU or heterosexual contact in East Central and Eastern Europe were around half as likely as MSM to have a suppressed viral load on ART, while we observed no differences in virological suppression across transmission categories in Western and Northern Europe. CONCLUSION: In our cohort, patterns of ART-coverage and virological suppression among key populations varied by geographical region, emphasizing the importance of tailoring HIV programmes to the local epidemic. PMID- 30289817 TI - CD4+ cell count recovery after combined antiretroviral therapy in the modern combined antiretroviral therapy era. AB - OBJECTIVE: To assess CD4 recovery after combined antiretroviral therapy (cART) initiation with sustained virologic control. DESIGN: Cohort study based on the French Hospital Database on HIV (FHDH-ANRS CO4). METHODS: We selected naive HIV-1 infected individuals initiating cART between 2006 and 2014 with CD4 cell counts less than 500 cells/MUl who achieved virologic control, defined as two consecutive viral loads less than 50 copies/ml. We estimated the cumulative incidence of CD4 recovery at least 500 cells/MUl and identified associated factors, considering 'virologic failure,' 'loss to follow-up' and 'death' as competing events. RESULTS: We analyzed 6050 individuals with a median follow-up of 14.2 months since virologic control. The cumulative incidence for CD4 recovery after 6 years of virologic control reached 69.7%. The main factor associated with CD4 recovery was the CD4 count at treatment initiation [subdistribution hazard ratio (sHR) 9.64, 95% confidence interval (95% CI) 8.12-11.43 for CD4 cell counts between 350 and 500 cells/MUl compared with CD4 cell counts <100 cells/MUl). A higher CD4/CD8 ratio at initiation was also independently associated with a higher probability of CD4 recovery [sHR 1.67; 95% CI 1.34-2.09] for a CD4/CD8 ratio >=1.00 vs. < 0.30). Higher viral load at initiation was also associated with a higher probability of CD4 recovery, whereas time to viral suppression was not. CONCLUSION: After 6 years of sustained virologic control, a large majority of the population achieved CD4 recovery. A higher CD4 cell count at initiation was a strong predictor of CD4 recovery and, to a lesser extent, a higher CD4/CD8 ratio at initiation. These results confirm the necessity of early treatment. PMID- 30289818 TI - Pharmacokinetic testing of a first generation cabotegravir prodrug in rhesus macaques. AB - Long-acting antiretrovirals can improve therapy and prevention for HIV-1 infection. Current long-acting cabotegravir (CAB LAP) can be administered every other month. Previously, we demonstrated that a myristoylated CAB prodrug encased in poloxamer 407 provided extended plasma drug concentrations. We now demonstrate that this first-generation nanoformulated prodrug can sustain plasma CAB concentrations above the PA-IC90 for four months in rhesus macaques. A 2.5-fold extension in CAB half-life and a 1.6-fold increase in area under the concentration-time curve were observed compared to CAB LAP. PMID- 30289820 TI - Dysbiosis in Snoring Children: an Interlink to Comorbidities? AB - BACKGROUND AND OBJECTIVES: Early microbial colonization has a key impact on infant health through nutritional, immunological, and metabolic programming. The origin of child snoring is multifactorial and complex, and may thereby also generate long-term health problems. The link between child snoring and gut microbes remains unclear, although indirect evidence exists regarding this relationship. This study aimed to characterize the connection between gut microbiota and child snoring. METHODS: In a prospective, observational CHILD SLEEP birth cohort study, gut microbiota in a subcohort of 43 of these children at 2 years of life was profiled with 16S ribosomal RNA gene amplicon sequencing. RESULTS: A higher abundance of the Proteobacteria phylum, the Enterobacteriaceae family, and Erysipelotrichaceae family, as well as a higher ratio of Firmicutes to Bacteroidetes were detected in snorers as compared to controls. Furthermore, snorers showed significantly lower microbial diversity and richness than non snorers. CONCLUSIONS: The snoring children manifest different gut microbiota as compared with healthy children. Considering that snoring and sleep disorders can be a source of long-term consequences, including cardiovascular, metabolic, immunological, neurocognitive and behavioural consequences, our results proposes early microbiota as a new treatment target. PMID- 30289819 TI - Targeted sequencing identifies a missense variant in the BEST3 gene associated with antihypertensive response to hydrochlorothiazide. AB - Chromosome 12q15 was identified in Genetic Epidemiology of Response Assessment (GERA) and replicated in Pharmacogenomic Evaluation of Antihypertensive Responses (PEAR) for its association with blood pressure (BP) response to hydrochlorothiazide (HCTZ). However, the functional variant is unknown and we aimed to identify the likely functional variants through targeted sequencing. The chromosome 12q15 region was sequenced in 397 best and worst responders to HCTZ in PEAR (N=199) and GERA (N=198) hypertensive study participants. Logistic regression was used for the association analysis adjusting for age, sex, race, and principal components 1 and 2. For validation, the significant single nucleotide polymorphism was tested for association with the change in systolic (DeltaSBP) and diastolic BP (DeltaDBP) post-treatment in the entire PEAR (N=370) and GERA (N=570) cohorts. A novel missense polymorphism (G>A, Pro383Leu) in BEST3, rs61747221, was significantly associated with better HCTZ response (P=0.0021, odds ratio=2.05). It was validated in the entire cohort of PEAR (DeltaSBP: P=0.021, beta=-1.60, DeltaDBP: P=0.023, beta=-1.08) and GERA (DeltaSBP: P=0.028, beta=-1.95, DeltaDBP: P=0.032, beta=-1.28). BEST3 encodes the calcium sensitive chloride channel in the vascular smooth muscle implicated in the regulation of BP, especially in response to vasoconstrictors like angiotensin II. These results suggest that BEST3 is involved in the chronic BP lowering mechanism of thiazides and highlight its importance as a genetic predictor of the BP response to thiazide diuretics. PMID- 30289821 TI - Parental Factors in Pediatric Functional Abdominal Pain Disorders: A Cross Sectional Cohort Study. AB - OBJECTIVES: Parental factors are suggested to play a role in pediatric irritable bowel syndrome (IBS) and functional abdominal pain - not otherwise specified (FAP NOS) and may influence treatment. Since studies on parental factors mainly focus on mothers, this study aims to compare physical health, psychological distress, personality dimensions and parenting behavior of both parents of children with IBS or FAP-NOS to parents of controls. METHODS: Parents of 91 children with IBS or FAP-NOS were included in this explorative cross-sectional cohort study. Parents of 74 age-matched healthy children were used as controls. Questionnaires were used to measure demographics, physical health, psychological distress and symptoms, personality dimensions and child-rearing practices. RESULTS: 59 mothers and 52 fathers of 61 children with IBS/FAP-NOS (response rate 61.0%) and 56 mothers and 49 fathers of 59 controls completed the study (response rate 70.9%). Mothers of children with IBS/FAP-NOS reported more physical problems. Psychological distress and symptoms, personality dimensions and child-rearing practices did not differ between mothers of both groups. Fathers of children with IBS/FAP-NOS had significantly lower scores on the child-rearing practice subscale of ignoring of unwanted behavior. In the IBS/FAP-NOS group, fathers were more depressed and less agreeable than mothers. No differences on all assessed outcomes were found between parents of children with IBS and children with FAP NOS. CONCLUSIONS: Mothers of children with IBS/FAP-NOS and healthy peers differ with respect to physical health. Fathers in both groups differ with respect to child-rearing style. Clinicians should be aware of these differences when treating children with these disorders. PMID- 30289822 TI - Pediatric chronic inflammatory bowel disease in a German statutory health INSURANCE - incidence rates from 2009 - 2012. AB - OBJECTIVE: The incidence of pediatric inflammatory bowel disease (PIBD) varies over time and geographic region. We attempted to generate incidence rates form German health insurance data. METHODS: We used health care data for 2009-2015 provided by BARMER, a major statutory health insurance company in Germany, insuring approx. 8% of the pediatric population. We applied a Canadian case definition for PIBD based on ICD coding, documentation of (ileo)colonoscopy and the number of PIBD related visits, without external validation for Germany. An internal validation of the specificity of the diagnosis by checking whether the identified incident cases had also prescriptions of PIPD specific drugs was performed. RESULTS: In 2012, 187 pediatric patients were newly diagnosed, accounting for an overall PIBD incidence of 17.41 (95%-CI: 15.08-20.10) per 100,000 insured children and adolescents from 0-17.9 years per year compared to 13.65/100,000 (95%-CI: 11.63-16.01) in 2009. The age specific incidence showed a steep increase as of the age of 7 years. The PIBD prevalence in 2012 was 66.29/100,000. CONCLUSION: In conclusion, the incidence of PIBD in 0 -17.9-year olds in Germany with health BARMER health insurance in 2012 is among the highest reported in the literature. PMID- 30289823 TI - Prosthetic Replacement of the Ocular Surface Ecosystem (PROSE) Versus Standard of Care for Postsurgical Lagophthalmos and Exposure Keratopathy: Trends in Visual Outcomes. AB - PURPOSE: To compare baseline characteristics and visual acuity outcomes in patients treated with prosthetic replacement of the ocular surface ecosystem (PROSE) versus other standard-of-care (SOC) treatments for postsurgical lagophthalmos and exposure keratopathy. METHODS: An institutional review board approved, retrospective cohort study of 45 consecutive patients (53 eyes) with postsurgical lagophthalmos and exposure keratopathy following oculoplastic or skull base surgeries treated between August 2011 and August 2017 was performed. Patients treated with PROSE (22 patients, 27 eyes) were identified by referrals made to the PROSE treatment program at Weill Cornell Medical College. Patients treated with SOC treatments (23 patients, 26 eyes) were identified by International Classification of Diseases-9 and International Classification of Diseases-10 search of billing records. SOC treatments included ocular surface lubrication (artificial tears and/or punctal plugs), tape tarsorrhaphy and/or moisture chamber, or surgical correction. The primary outcome measure was best corrected visual acuity converted to logMAR at baseline and at 1, 3, 6, and 12 months. Secondary outcome measures were subjective patient reports of improvement in vision and comfort, as well as presence of punctate epithelial erosions and/or corneal haze on slit-lamp examination before and after treatment. RESULTS: Average age for all patients was 52 +/- 22 years (range: 7-87). Twenty-eight (62%) of total patients were male. Baseline corrected logMAR visual acuity was 0.58 +/- 0.40 (20/76) for PROSE and 0.27 +/- 0.39 (20/37) for SOC cohorts (p < 0.001). Mean number of failed prior treatments was 8.3 +/- 3 for PROSE and 2.1 +/ 2 for SOC (p < 0.0001). Mean difference in logMAR visual acuity for PROSE versus SOC, respectively, from baseline to 1 month was 0.33 +/- 0.26 (3-line improvement) versus 0.01 +/- 0.17 (no line improvement; p < 0.0001), to 3 months was 0.31 +/- 0.23 (3-line improvement) versus 0.08 +/- 0.30 (4-letter improvement; p = 0.0004), to 6 months was 0.31 +/- 0.28 (3-line improvement) versus 0.10 +/- 0.36 (1-line improvement; p = 0.02), and to 12 months was 0.32 +/ 0.28 (3-line improvement) versus 0.12 +/- 0.34 (1-line improvement; p = 0.01). CONCLUSIONS: Patients with postsurgical lagophthalmos and exposure keratopathy treated with PROSE are more likely to have failed a higher number of treatments and have worse initial best-corrected visual acuities than those treated with SOC. Prosthetic replacement of the ocular surface ecosystem causes rapid and substantial visual improvement within 1 month of use compared with SOC, with little change beyond this time and sustained best-corrected visual acuity at 3, 6, and 12 months after treatment. PMID- 30289825 TI - Low-Flow Orbital Venous Malformation Masquerading as Rhabdomyosarcoma. AB - A 15-month-old male was referred for biopsy of presumed rhabdomyosarcoma in the setting of rapidly progressing left-sided proptosis. Examination revealed left periorbital edema and left hypoglobus. MRI revealed a soft-tissue density mass within the left lateral retrobulbar space. Several days later, he developed acute periorbital ecchymosis and increasing edema. With high suspicion for a vascular lesion, a CT scan was performed with dynamic arterial and venous imaging. Central filling was noted in the lateral retrobulbar component with increased enhancement on delayed venous imaging in the middle cranial fossa component favoring the diagnosis of a low-flow orbital venous malformation. In the setting of spontaneous orbital hemorrhage and risk of future vision loss, the decision was made to proceed with a combined neurosurgical approach treating the intracranial component and debulking the orbital component. This case highlights the importance of thorough radiographic evaluation prior to proceeding with a surgical procedure in the appropriate clinical context. PMID- 30289824 TI - Undifferentiated Pleomorphic Sarcoma Metastatic to the Orbit. AB - Undifferentiated pleomorphic sarcoma is a malignancy of mesenchymal origin, which was previously known as malignant fibrous histiocytoma. It is known to occur on rare occasion as a primary orbital tumor, but no known cases of metastatic orbital involvement have been reported since 2002, when the reclassification of these tumors took place. The authors report a patient who presented with a metastasis to the left orbit 2 years after undergoing treatment of a high-grade undifferentiated pleomorphic sarcoma of the right thigh. Histopathology of the orbital mass was similar to the primary tumor biopsy prior to neoadjuvant chemotherapy and radiation. The appearance was markedly altered in the subsequent excisional tissue, which showed treatment changes. Immunohistochemistry and genetic testing also supported the metastatic nature of the orbital lesion. The patient's tumor progressed rapidly despite systemic targeted therapy and orbital exenteration was performed. At 2 years follow up, the patient remained without evidence of tumor recurrence in the socket. PMID- 30289826 TI - Magnetic Resonance Elastography: An Update. PMID- 30289829 TI - New and Emerging Applications of Magnetic Resonance Elastography of Other Abdominal Organs. AB - Increasing clinical experience and ongoing research in the field of magnetic resonance elastography (MRE) is leading to exploration of its applications in other abdominal organs. In this review, the current research progress of MRE in prostate, uterus, pancreas, spleen, and kidney will be discussed. The article will describe patient preparation, modified technical approach including development of passive drivers, modification of sequences, and inversion. The potential clinical application of MRE in the evaluation of several disease processes affecting these organs will be discussed. In an era of increasing adoption of multiparametric magnetic resonance imaging approaches for solving complex abdominal problems, abdominal MRE as a biomarker may be seamlessly incorporated into a standard magnetic resonance imaging examination to provide a rapid, reliable, and comprehensive imaging evaluation at a single patient appointment in the future. PMID- 30289830 TI - Quantifying Tumor Stiffness With Magnetic Resonance Elastography: The Role of Mechanical Properties for Detection, Characterization, and Treatment Stratification in Oncology. AB - The viscoelastic properties of tissue are significantly altered with the development of tumors and these alterations can be assessed with magnetic resonance elastography (MRE). Accurate detection and characterization of malignant and benign lesions can be obtained by quantifying tumor stiffness, improving the specificity and diagnostic accuracy of conventional magnetic resonance imaging. Furthermore, MRE can be used to stratify patients for treatment based on risk of normal tissue toxicity and surgical considerations including consistency and adherence of the tumor to surrounding structures. MRE is a reliable reproducible technique demonstrated in studies that include both patients with cancer and normal volunteers, and an average technical failure rate of <1%. The addition of MRE into a multiparametric magnetic resonance imaging assessment may improve the diagnosis and treatment of cancer. PMID- 30289827 TI - Stiffness and Beyond: What MR Elastography Can Tell Us About Brain Structure and Function Under Physiologic and Pathologic Conditions. AB - Brain magnetic resonance elastography (MRE) was developed on the basis of a desire to "palpate by imaging" and is becoming a powerful tool in the investigation of neurophysiological and neuropathological states. Measurements are acquired with a specialized MR phase-contrast pulse sequence that can detect tissue motion in response to an applied external or internal excitation. The tissue viscoelasticity is then reconstructed from the measured displacement. Quantitative characterization of brain viscoelastic behaviors provides us an insight into the brain structure and function by assessing the mechanical rigidity, viscosity, friction, and connectivity of brain tissues. Changes in these features are associated with inflammation, demyelination, and neurodegeneration that contribute to brain disease onset and progression. Here, we review the basic principles and limitations of brain MRE and summarize its current neuroanatomical studies and clinical applications to the most common neurosurgical and neurodegenerative disorders, including intracranial tumors, dementia, multiple sclerosis, amyotrophic lateral sclerosis, and traumatic brain injury. Going forward, further improvement in acquisition techniques, stable inverse reconstruction algorithms, and advanced numerical, physical, and preclinical validation models is needed to increase the utility of brain MRE in both research and clinical applications.

AB - OBJECTIVE: The aim of this study was to estimate the association between organochlorine pesticides and polychlorinated biphenyls (PCBs) and multiple myeloma (MM). METHODS: The risk of MM from organochlorine compounds was examined in a population-based case-control study in British Columbia, Canada. Congeners of PCBs and pesticides or pesticide metabolites were measured in plasma of 325 cases and 327 controls. RESULTS: Most organochlorine analytes showed a significant association with MM. The strongest association (highest vs lowest quartile) was oxychlordane (odds ratio = 7.44; 95% confidence interval = 4.19 to 13.21). No heterogeneity was detected between organochlorines levels and MM subtypes. Only oxychlordane and beta-hexachlorocyclohexane (beta-HCCH) were identified as significant independent predictors of MM. CONCLUSION: Our study provides evidence that organochlorines contribute to the risk of MM. PMID- 30289828 TI - Magnetic Resonance Elastography of Liver: Current Update. AB - The first clinical application of magnetic resonance elastography (MRE) was in the evaluation of chronic liver disease (CLD) for detection and staging of liver fibrosis. In the past 10 years, MRE has been incorporated seamlessly into a standard magnetic resonance imaging (MRI) liver protocol worldwide. Liver MRE is a robust technique for evaluation of liver stiffness and is currently the most accurate noninvasive imaging technology for evaluation of liver fibrosis. Newer MRE sequences including spin-echo MRE and 3 dimensional MRE have helped in reducing the technical limitations of clinical liver MRE that is performed with 2D gradient recalled echo (GRE) MRE. Advances in MRE technology have led to understanding of newer mechanical parameters such as dispersion, attenuation, and viscoelasticity that may be useful in evaluating pathological processes in CLD and may prove useful in their management.This review article will describe the changes in CLD that cause an increase in stiffness followed by principle and technique of liver MRE. In the later part of the review, we will briefly discuss the advances in liver MRE. PMID- 30289835 TI - Re: Health Status of Workers Exposed to Perfluorinated Alkylate Substances. PMID- 30289831 TI - Advances and Future Direction of Magnetic Resonance Elastography. AB - The mechanical properties of soft tissues are closely associated with a variety of diseases. This motivates the development of elastography techniques in which tissue mechanical properties are quantitatively estimated through imaging. Magnetic resonance elastography (MRE) is a noninvasive phase-contrast MR technique wherein shear modulus of soft tissue can be spatially and temporally estimated. MRE has recently received significant attention due to its capability in noninvasively estimating tissue mechanical properties, which can offer considerable diagnostic potential. In this work, recent technology advances of MRE, its future clinical applications, and the related limitations will be discussed.

PMID- 30289841 TI - Persistent Postural-Perceptual Dizziness-A Systematic Review of the Literature for the Balance Specialist. AB - OBJECTIVE: To present a systematic review of the current data on persistent postural-perceptual dizziness (PPPD), a useful and relatively new diagnosis for a disorder that has previously been known by many different names. In addition, to discuss diagnostic criteria and management strategies for this condition with the otologist in mind. DATA SOURCES: CINAHL, Embase, PubMed, Medline, PsycINFO, PubMed, Google Scholar. REVIEW METHOD: The phrase "persistent postural-perceptual dizziness" and its acronym "PPPD" were used. RESULTS: From 318 articles, 15 were selected for full analysis with respect to PPPD. Most were case-control studies, with one consensus paper from the Barany Society available. Overall, the pathophysiology of PPPD remains relatively poorly understood, but is likely to be a maladaptive state to a variety of insults, including vestibular dysfunction and not a structural or psychiatric one. Cognitive behavioral therapy, vestibular rehabilitation, selective serotonin uptake inhibitors (SSRIs), and serotonin norepinephrine reuptake inhibitors (SNRIs) all seem to have a role in its management. CONCLUSIONS: PPPD is useful as a diagnosis for those treating dizziness as it helps to define a conglomeration of symptoms that can seem otherwise vague and allows for more structured management plans in those suffering from it. PMID- 30289842 TI - What Effect Does Smoking Have on the Surgical Closure of Tympanic Membrane Perforations? A Review. AB - OBJECTIVES: The link between cigarette smoking and outcome following surgical repair of tympanic membrane perforation is unclear. The objective of this study was to conduct a systematic review on the link between smoking and success rate following surgical repair of tympanic membrane perforations. MATERIALS AND METHODS: Systematic review performed using the following data sources: 1) Cochrane central register of controlled trials (1997 to April 30, 2018), 2) Medline (February 1948 to April 30, 2018), and 3) Embase (1975 to April 30, 2018). Inclusion criteria for this study was: 1) studies reporting surgical closure of tympanic membrane perforations in smokers, 2)primary and revision cases, 3) English language literature, 4) minimum follow-up period of 6 months, and 5) pre and postoperative audiogram. The exclusion criteria were: 1) no identifiable data on smokers in reported outcomes, 2) less than 6 months follow up, 3) no audiometric outcomes, and 4) non-English language articles. RESULTS: A total of 75 studies were identified on initial search and 8 were eligible for the study. All studies were of level 4 evidence. In these eight studies, overall surgical closure of tympanic membrane perforation was successful in 512/577 (88.7%) of nonsmokers and 151/197 (76.6%) in smokers. This difference was statistically significant. CONCLUSIONS: Smokers may have a lower success rate compared against nonsmokers for surgical repair of tympanic membrane perforations. Our review has limitations and more prospective high-quality controlled trials are required to further study this association. PMID- 30289843 TI - Peripheral Vestibular Disorders: An Epidemiologic Survey in 70 Million Individuals. AB - BACKGROUND: Dizziness is a common complaint in medicine. Nevertheless, there is a lack of valid data concerning the age and gender distribution of dizziness disorders within a larger population. Therefore, the aim of the present study is to undertake a representative epidemiological survey that examines all age groups of an entire population and describes the age and gender distribution of the most common peripheral vestibular disorders. METHODS: A population-based epidemiological survey based on confirmed ICD-10 codes, of an entire national population was performed. The population-based data of 70,315,919 patients were leveraged, as provided by 123 statutory health insurance companies in Germany. Patients of all age groups were analyzed. Outcome measures were age and gender distribution and the prevalence of unspecific vertigo, Meniere's disease, benign paroxysmal positional vertigo, vestibular neuritis, and other peripheral vestibular disorders. RESULTS: The prevalence among the recorded diagnoses was 6.5% (6,461/100,000 individuals), with women (N = 2,973,323; 65.4%) being significantly more frequently affected by vertigo than men (N = 1,570,240; 34.6%; p < 0.001). Vertigo is rare in childhood (i.e., up to 10-14 yr of age). Subsequently, the prevalence of the analyzed diseases increases with age, up to a peak between 74 and 94 years. CONCLUSIONS: The results demonstrate that peripheral vestibular disorders are common in a developed country, across all age groups and a specific distribution of these disorders can be identified for every age group and gender. The impact of these disorders on the German healthcare system is currently underestimated. PMID- 30289844 TI - Prevalence of Radiographic Cochlear-Facial Nerve Dehiscence. AB - OBJECTIVE: To determine the prevalence of radiographic cochlear-facial nerve dehiscence (CFD). STUDY DESIGN: Retrospective radiological study. SETTING: Two tertiary-referral centers. PATIENTS: Two hundred six temporal-bone computed tomography (CT) scans (405 total ears) of otology/neurotology patients from two academic institutions between the years 2014 and 2017. INTERVENTION: Diagnostic. MAIN OUTCOME MEASURES: The cochlear-facial nerve partition width (CFPW) was measured on coronal CT sections and defined as the shortest distance between the cochlear basal turn and facial nerve (FN) labyrinthine segment. We used logistics regression analyses to determine positive predictors for radiographic evidence of CFD. RESULTS: The overall prevalence of radiographic CFD was 5.4% (22/406 ears). 9.2% of patients (19/206) had CFD. Of these 19 patients, only one patient had mixed hearing loss that could not be explained by any other vestibular or auditory etiology. Three out of 206 patients had dehiscence in both ears (1.4%). The average CFPW was 0.6 +/- 0.2 mm, and fallopian canal width was 1.1 +/- 0.02 mm (n = 405). Older age, use of traditional CT scans, and thinner CT slice thickness were significant predictors for radiographic CFD. CONCLUSIONS: The radiographic prevalence of CFD is higher than what is reported in histologic studies, and may over-estimate the true prevalence of CFD. The clinician should keep this in mind when considering this as potential cause for third-window symptoms. PMID- 30289845 TI - In vivo Assessment of an Endolymphatic Hydrops Gradient Along the Cochlea in Patients With Meniere's Disease by Magnetic Resonance Imaging-A Pilot Study. AB - OBJECTIVE: To assess three strategies for evaluation and description of potential endolymphatic hydrops (EH) gradients along the cochlea in patients with Meniere's disease. STUDY DESIGN: Prospective observational study. METHODS: Ten patients with definite Meniere's disease revealed by magnetic resonance imaging were included in this prospectively conducted pilot study. The presence of cochlear endolymphatic hydrops as well as a potential hydrops gradient along the cochlea were subjectively evaluated by two readers. Furthermore, both readers performed planimetric measurements of the relative extent of endolymphatic hydrops in the cochlear turns for calculation of an apico-basal-index (ABI) and an average gradient slope of the endolymphatic hydrops. These models were correlated with the available pure tone audiometry (PTA). RESULTS: Qualitatively, 13 of 16 inner ears presented an apical EH distribution. The median ABI was 1.69 for patients with low-tone hearing loss and 1.17 for patients with a flat PTA curve (p = 0.03). The median EH slope was 7.44 and correlated with the steepness of the PTA (rho = 0.583; p = 0.018). The subjective analysis and the slope model were best fit for prediction of a low-tone hearing loss type with sensitivities of 100% (specificity, 42.86%) and 88.9% (specificity, 71.4%), respectively. The inter reader agreement in all three approaches was considered substantial to perfect. CONCLUSION: The presented qualitative approach and the slope model represent reliable methods for the description of a potential EH gradient along the cochlea. Furthermore, the average EH steepness along the cochlea correlates with the type of hearing loss. PMID- 30289846 TI - Cochlear Implantation in Chronic Otitis Media: Investigation of Long-term Speech Comprehension and Rate of Complications. AB - OBJECTIVE: To analyze the long-term speech comprehension and rate of complications of cochlear implantation in chronic otitis media. STUDY DESIGN: Retrospective data analysis. SETTING: Tertiary referral center with a large cochlear implant program. MAIN OUTCOME MEASURE: Speech perception scores in quiet and background noise and rate of complications. PATIENTS: Forty ears from a total of 38 patients with a mean age of 63.28 +/- 2.16 years at the time of implantation were included. RESULTS: Patients with a history of multiple ear surgeries, with no alternative option for hearing restoration than a cochlear implant, were implanted with satisfactory results in regard to speech comprehension. Preoperative bone conduction PTA4 correlated to postoperative speech comprehension scores in background noise. The rate of complications was low, but higher than in cases of cochlear implantation in normal middle ears. CONCLUSION: Cochlear implantation in chronic otitis media can be a satisfactory and safe procedure, if the surgery technique and aftercare is appropriate to the altered anatomy. PMID- 30289848 TI - A Gunshot Injury to Temporal Bone: Saved by the Bone. PMID- 30289847 TI - Can Preoperative High Resolution Computed Tomography Be Rationalized in Adult Cochlear Implant Candidates? AB - OBJECTIVE: To establish whether criteria can be used to identify patients who do not need high resolution computed tomography (HRCT) scans before cochlear implant operations, by retrospectively applying a preoperative selection pathway, the Cambridge Cochlear Implant Protocol (CCIP). STUDY DESIGN: Retrospective case series. SETTING: Tertiary referral center, Queen Elizabeth Hospital, Birmingham, UK (QEHB). PATIENTS: One hundred adult patients receiving primary cochlear implantation (CI) operations from April 2015 to July 2016 performed at the QEHB who received preoperative HRCTs. MAIN OUTCOME MEASURES: Etiology of hearing loss and anatomical abnormalities were collected by reanalyzing HRCT scans. Patients were retrospectively grouped according to criteria to restrict HRCT use derived from the Cambridge Cochlear Implant Programme (CCIP). The two main outcomes, recorded management change and significant abnormalities, were compared between the two CCIP groups, scanned and not scanned. RESULTS: Twenty-six patients had significant abnormalities detected on imaging, 16 in the scanned group and 10 in the not scanned group (p = 0.152). Five patients had a recorded management change as a result of HRCT scan, four scanned group, one not scanned group (p = 0.107). Significant abnormalities and recorded management change were seen across all etiological subgroups of hearing loss. CONCLUSION: The anatomy within the temporal bone is variable amongst CI recipients. Recorded management change and significant abnormalities occurred in both CCIP groups and across many etiologies of hearing loss patients. No specific group, based on the etiology of their hearing loss could be identified that do not require preoperative HRCT. Therefore, it is recommended that all CI patients should continue to receive preoperative HRCT imaging. PMID- 30289849 TI - Plasma Angiopoietin-2/-1 Ratio is Elevated and Angiopoietin-2 Levels Correlate with Plasma Syndecan-1 Following Pediatric Trauma. AB - BACKGROUND: Angiopoietin-1 (Agpt-1) and Agpt-2 are cytokine regulators of vascular endothelial integrity. Elevated plasma Agpt-2 levels and ratios of Agpt 2:Agpt-1 are associated with adverse outcomes in adult trauma and pediatric sepsis populations. However, the behavior of the angiopoietins after pediatric trauma has not been characterized, and their relationship to endothelial glycocalyx damage, indicated by plasma syndecan-1 (Syn-1) levels, has not been established. METHODS: We performed a secondary analysis of prospectively collected data from 52 pediatric trauma patients and 12 control patients at a level one pediatric trauma center from 2013 to 2016. We measured Agpt-1, Agpt-2, and Syn-1 levels from plasma taken upon hospital arrival and 24 hours after admission. Angiopoietin levels were compared to controls, and the correlation between Agpt-2 and Syn-1 was assessed. RESULTS: Plasma Agpt-1 and Agpt-2 levels are elevated immediately after pediatric trauma compared to controls. At 24 hours, trauma patients demonstrated significantly elevated plasma Agpt-2:Agpt-1 ratios relative to controls due to decline of Agpt-1 levels to near that of controls. Higher 24-hour Agpt-2 levels are associated with more hypoperfusion, and elevated 24-hour Agpt-2:Agpt-1 ratios are associated with adverse clinical outcomes. Significant positive correlations between Agpt-2 and Syn-1 upon admission and at twenty-four hours after injury were identified. CONCLUSION: Our findings suggest dysregulation of circulating angiopoietins after pediatric trauma that may be linked to endothelial glycocalyx injury. Larger prospective studies are needed to validate these findings and determine the relationship of Agpt-2 with other markers of endotheliopathy. PMID- 30289850 TI - Whole Exome Sequencing of Adult and Pediatric Cohorts of the Rare Vascular Disorder Systemic Capillary Leak Syndrome. AB - OBJECTIVE: Systemic capillary leak syndrome (SCLS) is a rare disorder that presents with episodes of hypovolemic shock. The extent to which genetic abnormalities contribute to SCLS is unknown. We identified pediatric and adult cohorts with characteristic clinical courses. We sought to describe the clinical characteristics of both cohorts, identify a possible genetic contribution to SCLS, and demonstrate that whole exome sequencing (WES) may be conducted by critical care providers. DESIGN: Prospective observational study of WES of nine adult and eight pediatric SCLS patients and available unaffected first-degree relatives. SETTING: Tertiary children's hospitals and referral research laboratory. PATIENTS: Children and adults with SCLS. INTERVENTIONS: None. MEASUREMENTS: Patients and available first-degree relatives underwent WES. Data were analyzed for rare homozygous, bi-allelic, de novo and heterozygous variants with allelic enrichment and metabolic pathway analyses. MAIN RESULTS: Children with SCLS presented at a younger age with episodes similar to those experienced by adults. All patients and available relatives underwent satisfactory WES. No overlapping gene variants or metabolic pathways were identified across all SCLS patients. Multiple candidate genes with homozygous or bi-allelic mutations were identified in individual subjects with SCLS. There was no significant enrichment of genes with rare heterozygous variants. CONCLUSIONS: The clinical characteristics of children and adults with SCLS are similar. We did not identify a uniform germline exomic genetic etiology for SCLS. WES identified several candidate genes in individual patients for future research. WES is a viable way for critical care providers to investigate the etiology of diseases with presumed genetic contributions. PMID- 30289851 TI - Early Differential Value of Plasma Presepsin on Infection of Trauma Patients. AB - OBJECTIVE: Early differential diagnosis of an infection in a trauma patient is likely to have a significant influence on the prognosis. In the present study, we evaluated the early differential value of plasma presepsin, procalcitonin (PCT), C-reactive protein (CRP), and white blood cells (WBCs) on infection in trauma patients. METHODS: Trauma patients were divided into noninfected (n = 89) and infected trauma groups (n = 68); healthy adult volunteers (n = 60) and patients having sterile surgery (n = 60) were enrolled as the controls. Plasma presepsin, PCT, CRP, and WBC counts were measured and the injury severity score (ISS) was calculated. RESULTS: Plasma presepsin levels within the first 3 d of admission were only significantly increased in the infected trauma group, but not in the noninfected trauma and sterile groups. This indicated that presepsin might have an ability to differentiate the infection in trauma patients; however, plasma PCT, CRP, and WBCs were significantly increased in both the infected and noninfected trauma patients. Binary logistic regression analysis showed that only increased plasma presepsin, PCT, and ISS were significantly associated with an increased likelihood of infection in trauma patients. Both presepsin and PCT were valuable for diagnosing infection; presepsin had a higher area under the curve than PCT. CONCLUSIONS: Presepsin might be a superior biomarker for early differentiation of infection in trauma patients; however, trauma stress elevates PCT, CRP, and WBCs even in the absence of infection; therefore, caution is advised when using these indicators to diagnose infection. PMID- 30289852 TI - Remote Intestinal Injury Early After Experimental Polytrauma and Hemorrhagic Shock. AB - Dysfunction of the gut-blood barrier plays an important role in many diseases, such as inflammatory bowel disease, hemorrhagic shock (HS) or burn injury. However, little is known about gut barrier dysfunction after hemodynamically instable polytrauma (PT). Therefore, we aimed to evaluate the effects of PT and HS on remote intestinal damage and barrier dysfunction, especially regarding the role of Zonula occludens protein 1 (ZO-1) as an important tight junction protein.Male C57BL/6 mice were subjected to either PT (thorax trauma, closed head injury, soft tissue injury and distal femoral fracture), 60 min of pressure controlled HS (30 +/- 5 mmHg), or PT+HS, or sham procedures.Animals of all trauma groups showed an increase in abdominal girth and dilation of the intestine during the experimental period, which was largest in the PT+HS group. Increased blood tissue permeability to albumin (assessed by Evans blue dye) was found in the HS group. Experimental groups showed a slight increase in plasma concentration of intestinal fatty acid binding protein and some intestinal damage was histologically detectable. Of note, PT+HS animals revealed significantly reduced expression of ZO-1 in intestinal epithelial cells. In an in vitro model, stimulation of human colon epithelial cells with peptidoglycan, but not with lipopolysaccharide, resulted in elevated secretion of proinflammatory cytokines, reflecting inflammatory activity of the intestinal epithelium.Taken together, PT and HS lead to increased permeability of the gut-blood barrier. Bacterial components may lead to production of inflammatory and chemotactic mediators by gut epithelial cells, underlining the role of the gut as an immunologically active organ. PMID- 30289853 TI - Distinct Dynamics of Stem and Progenitor Cells in Blood of Polytraumatized Patients. AB - Endogenously mobilized stem and progenitor cells (SPCs) or exogenously provided SPCs are thought to be beneficial for trauma therapy. However, still little is known about the synchronized dynamics of the number of SPCs in blood after severe injury and parameters like cytokine profiles that correlate with these numbers. We determined the number of hematopoietic stem cells, common myeloid progenitors, granulocyte-macrophage progenitors and mesenchymal stem/stromal cells in peripheral blood (PB) 0-3 h, 8 h, 24 h, 48 h and 120 h after polytrauma in individual patients (injury severity score >= 21). We found that the number of blood SPCs follow on average a synchronous, inverse bell-shaped distribution, with an increase at 0-3 h, followed by a strong decrease, with a nadir in SPC numbers in blood at 24 h or 48 h. The change in numbers of SPCs in PB between 48 h and 120 h revealed two distinct patterns: Pattern 1 is characterized by an increase in the number of SPCs to a level higher than normal, pattern 2 is characterized by an almost absent increase in the number of SPCs compared to the nadir. Changes in the concentrations of the cytokines CK, MDC, IL-8, G-CSF Gro alpha, VEGF and MCP-1 correlated with changes in the number of SPCs in PB or were closely associated with Pattern 1 or Pattern 2. Our data provide novel rationale for investigations on the role of stem cell mobilization in polytraumatized patients and its likely positive impact on trauma outcome.

This editorial discusses leadership presence as an essential skill for professional case management practice and the impact of such relationships on the client/support system experience of care. It also presents a framework for building impactful and therapeutic relationships. In addition, it offers a list of key strategies that contribute to the success of the professional case manager. PMID- 30289855 TI - The New Age of Bullying and Violence in Health Care: Part 4: Managing Organizational Cultures and Beyond. AB - : Disrespect among the health and behavioral health workforce may have reached the point of no return. The industry is on heightened alert, as the disruptive behaviors of bullying and lateral violence, plus escalating incidents of workforce harassment and workplace violence incidents, impact every practice setting. These behaviors contribute to concerns around client and professional safety, quality-of-care processes, as well as workforce retention and mental health. PURPOSE/OBJECTIVES: This article: PRIMARY PRACTICE SETTING(S):: Applicable to all health and behavioral health settings where case management is practiced. FINDINGS/CONCLUSIONS: Despite glaring improvements in how care is rendered and an enhanced focus on quality delivery of care, organizations must address cultures that support as opposed to negate disruptive workplace behaviors. The emerging regulatory and organizational initiatives to reframe the delivery of care will become meaningless without consistent attention to enforcement of regulatory, policy, and prevention actions. IMPLICATIONS FOR CASE MANAGEMENT PRACTICE: Professionals who hesitate to confront and address incidents of disruptive and oppressive behavior in the health care workplace potentially practice unethically. Bullying has fostered a dangerous culture of silence in the industry, one which impacts client safety, quality care delivery, plus has longer term behavioral health implications for the professionals striving to render care. Add the escalating numbers specific to workplace violence and the trends speak to an atmosphere of safety and quality in the health care workplace that puts clients and professionals at risk.

AB - PURPOSE OF STUDY: Many hospitals established telephone follow-up (TFU) programs to improve care transitions and reduce hospital readmissions. However, there is a lack of knowledge on how to increase the outreach of TFU programs. This integrative review aims to answer the clinical practice question, "What is the best practice for increasing telephone follow-up reach rates post-hospital discharge?" PRIMARY PRACTICE SETTING: The primary setting evaluated in this review was hospital-based phone call programs that are conducting post-hospital discharge TFU. METHODOLOGY: In this integrative review, we searched studies published between January 2003 and November 2017. We searched 5 electronic databases including PubMed, EMBASE, CINAHL, Web of Science, and Cochrane. The Johns Hopkins Nursing Evidence-Based Practice model was used to critically analyze and synthesize the selected articles. RESULTS: Nine articles were reviewed, and this study uncovered that pre-hospital face-to-face meeting might increase TFU reach rates. However, most studies calculated reach rates using only frequencies/percentages. This contributed to our low-quality rating on most of the reviewed studies. IMPLICATIONS FOR CASE MANAGEMENT PRACTICE: This review identified that TFU, as a component of a care coordination program, may reduce hospital readmissions and control health care utilization. However, few studies (n = 2) used TFU reach rates as a major study outcome to determine the impact of face-to-face meetings on phone outreach. Therefore, the evidence is limited to inform case management practice to increase phone outreach post-hospital discharge. It is recommended to conduct further research and test different methods that may increase phone outreach.

AB - PURPOSE: To evaluate the ComPass program by (1) effectiveness in reducing 30-day hospital readmissions, (2) reach of program into target population, and (3) implementation of key program elements. PRIMARY PRACTICE SETTING: An academic hospital in New England (John Dempsey Hospital). METHODOLOGY AND SAMPLE: Retrospective analysis of Medicare fee-for-service (FFS) beneficiaries hospitalized at John Dempsey Hospital between May 1, 2012, and November 30, 2014. RESULTS: The program reached 34% of eligible Medicare FFS beneficiaries (n = 832; 61% female, mean age = 79 years). The unadjusted 30-day all-cause readmission rate decreased from 21% to 16.2% (p = .03). Implementation was high for postdischarge phone calls (89%) but low for home visits (34%). The mean change in patient activation scores following completion of the program was 0.15 (SD = 4.79), with no change in patient activation level, chi (6) = 3.82, p = .70. IMPLICATIONS FOR CASE MANAGEMENT PRACTICE: The ComPass program was consistent with the philosophy and standards of case management practice. Case managers will want to utilize an evidence-based instrument with real-time information to identify patients at risk for 30-day readmission. A physical presence of ComPass coaches within the hospital enabled a strong hospital-community-based organization (CBO) partnership, facilitating the coordination, communication, and collaboration. Case managers will want to advocate for policy incentivizing hospital-CBO partnerships. Patient activation is essential; case managers may benefit from training in motivational interviewing to improve patient activation and outcomes. Additional research is needed to further elucidate and mitigate barriers to posttransition home visits and patient activation.

PMID- 30289859 TI - Improving Functional Assessment in Older Adults Transitioning From Hospital to Home. AB - PURPOSE/OBJECTIVES: The purpose of this article is to highlight how scientists have assessed all components of functional status in older adults transitioning from hospital to home to date, discuss ways of improving assessment of functional status, and discuss implications for case management research and practice. PRIMARY PRACTICE SETTING(S): This article focuses on case management of older adults transitioning from hospital to home. FINDINGS/CONCLUSIONS: There any many ways to assess functional status, including basic activities of daily living (BADL), instrumental activities of daily living (IADL), and other nonphysical domains of function such as leisure, social, and productive activities. However, assessment of function in older adults transitioning from hospital to home is primarily limited to BADL. Nonphysical domains of functional status have been linked to important outcomes in community-dwelling older adults and could give clinicians and researchers a better understanding of how older adults are functioning, as well as allow for earlier recognition of those who are beginning to experience functional decline. IMPLICATIONS FOR CASE MANAGEMENT PRACTICE: In case management, it is important to ask older adults about goals regarding their functional status and how they think about their functioning in the hospital and at home. Early identification of older adults' functional goals while in the hospital is the first step toward regaining their ideal or premorbid function after discharge to home. To best determine baseline functional status, we may need to consider assessments that can measure multiple domains of functioning in older adults, such as the Sickness Impact Profile. Gaining a more comprehensive understanding and assessment of functional status for hospitalized older adults would help inform discharge destinations and improve transitions in care.

AB - Sekiguchi, Y, Huggins, RA, Curtis, RM, Benjamin, CL, Adams, WM, Looney, DP, West, CA, and Casa, DJ. Relationship between heart rate variability and acute:chronic load ratio throughout a season in NCAA D1 men's soccer players. J Strength Cond Res XX(X): 000-000, 2018-The purpose of this study was twofold: (a) to examine the relationship between heart rate variability (HRV) and acute:chronic workload ratio (ACWR)-based training load (TL) metrics and (b) to examine relationships across various A:C ratio-based TL metrics. Heart rate variability in 23 male college soccer players (mean +/- SD; age, 21 +/- 1 years; body mass, 80.3 +/- 5.8 kg; height, 181.9 +/- 6.5 cm; %body fat, 11.9 +/- 2.0%; and V[Combining Dot Above]O2max, 51.9 +/- 5.0 ml.kg.min) was measured at 5 time points: week(W)1, W3, W7, W12, and W14 during the 2015 NCAA men's soccer season. Heart rate variability was calculated from beat to beat intervals using a heart rate monitor. Players donned a global position satellite-enabled device that measured the following TL metrics: session time (ST), Player Load (PL), PL.min, and total distance (TD). Acute:chronic workload ratio was calculated for each TL metric: ACWR-based ST (ACWRST), ACWR-based PL (ACWRPL), ACWR-based PL.min (ACWRPLM), and ACWR-based TD (ACWRTD): ACWR = week average TLs/mo average (30 +/- 1 days) TLs. Relationships between HRV and ACWR-based each TL metric were evaluated using mixed effects models. Tukey pairwise comparisons were used to examine differences between types of ACWR-based TL metrics. An increase in ACWRST significantly reduced HRV throughout a season (-7.4 +/- 3.6 m.s; p = 0.04). There were significant differences between ACWRPLM and ACWRST, ACWRPL and ACWRTD at W1, ACWRPLM and ACWRST at W3 (p < 0.05). In conclusion, ACWRST, ACWRPL, and ACWRTD were significantly different from ACWRPLM. ACWRST was found to significantly predict HRV; higher ACWRST was significantly associated with lower HRV. Therefore, tracking of the ACWR using ST may help to optimize athlete's physiological state throughout a season.

AB - Fiogbe, E, Vassimon-Barroso, V, Catai, AM, de Melo, RC, Quiterio, RJ, Porta, A, and Takahashi, ACdM. Complexity of knee extensor torque: effect of aging and contraction intensity. J Strength Cond Res XX(X): 000-000, 2018-Assessing the knee extensors' torque complexity in old adults is relevant because these muscles are among the most involved in functional daily activities. This study aimed to investigate the effects of aging and isometric contraction intensity on knee extensor torque complexity. Eight young (24 +/- 2.8 years) and 13 old adults (63 +/- 2.8 years) performed 3 maximal (maximum voluntary contraction [MVC], duration = 10 seconds) and submaximal isometric contractions (SICs, targeted at 15, 30, and 40% of MVC, respectively) of knee extensors. Torque signals were sampled continuously, and the metrics of variability and complexity were calculated basing on the SIC torque data. The coefficient of variation (CV) was used to quantify the torque variability. The torque complexity was determined by calculating the corrected approximate entropy (CApEn) and sample entropy (SampEn) and its normalized versions (NCApEn and NSampEn). Young subjects produced greater isometric torque than old adults, and the CV was similar between both groups except at the highest force level (40% MVC) where young subjects' value was higher. The major novel finding of this investigation was that although the knee extensor torque complexity is reduced in old adults, its relationship with contraction intensity is similar to young subjects. This means that despite the age-related decrease of the interactions between the components of the neuromuscular system, the organization of force control remains preserved in old adults, at least up to just below the force midrange.

Pacing profiles of Olympic and International Association of Athletics Federations World Championship long distance runners. J Strength Cond Res XX(X): 000-000, 2018-The aim of this study was to analyze the pacing profiles of Olympic and International Association of Athletics Federations (IAAF) World Championship long-distance finalists, including the relationship with their recent best times. The times for each 1,000 m split were obtained for 394 men and women in 5,000- and 10,000-m finals at 5 championships. Athletes' best times from the previous 32 months were also obtained. Similar pacing profiles were used by athletes grouped by finishing position in 5,000-m races. Women adopted a more even pacing behavior, highlighting a possible sex-based difference over this distance. Pacing behavior over 10,000 m was more similar between men and women compared with over 5,000 m. The main difference between men and women was that in the men's 10,000 m, as in the men's 5,000 m, more athletes were able to follow the leading group until the final stages. There were large or very large correlations between athletes' best times from the previous 32 months and their result; the fastest finishers also ran closer to their previous 32 months' best times. Despite differences in pacing behavior between events, long-distance runners should nonetheless stay close to the front from the beginning to win a medal. PMID- 30289869 TI - Individualizing Acceleration in English Premier League Academy Soccer Players. AB - Abbott, W, Brickley, G, Smeeton, NJ, and Mills, S. Individualizing acceleration in English Premier League academy soccer players. J Strength Cond Res 32(12): 3512-3519, 2018-Global thresholds are typically used to band acceleration dependent on intensity. However, global thresholds do not account for variation in individual capacities, failing to quantify true intensity of acceleration. Previous research has investigated discrepancies in high-speed distance produced using global and individual speed thresholds, not yet investigated for acceleration. The current aim was to investigate discrepancies between global and individual thresholds when quantifying acceleration tasks. Acceleration data were recorded for 31 professional soccer players, using 10-Hz global positioning systems devices. Distances traveled performing low-, moderate-, and high intensity acceleration were calculated for athletes using global and individual thresholds. Global acceleration thresholds for low-, moderate-, and high intensity acceleration were classified as 1-2, 2-3, and >3 m.s, respectively, with individual thresholds classified as 25-50%, 50-75%, and >75% of maximum acceleration, respectively. Athletes were grouped low (LO), medium (ME), or high (HI) maximum accelerative capacity, determined using 3 maximal 40-m linear sprints. Two-way mixed-design analyses of variance were used to analyze differences in acceleration distances produced between analysis methods and athlete groups. No significant differences were identified between analysis methods for LO. For ME, no significant differences were demonstrated for low intensity. Moderate- and high-intensity acceleration distances were significantly higher for global compared with individual analysis method (p < 0.01). For HI, significantly higher acceleration distances were produced for all acceleration intensities using global thresholds (p < 0.01). Significant differences identified between analysis methods suggest practitioners must apply caution when using global thresholds. Global thresholds do not account for individual capacities and may provide an inaccurate representation of relative intensity of acceleration tasks.

AB - Weakley, J, Wilson, K, Till, K, Banyard, H, Dyson, J, Phibbs, P, Read, D, and Jones, B. Show me, tell me, encourage me: The effect of different forms of feedback on resistance training performance. J Strength Cond Res XX(X): 000-000, 2018-When performing resistance training, verbal kinematic feedback and visual kinematic feedback are known to enhance performance. In addition, providing verbal encouragement can assist in the attenuation of fatigue. However, the effects of these forms of feedback have never been compared. Consequently, this study aimed to quantify the effects of verbal kinematic feedback and visual kinematic feedback, and verbal encouragement on barbell velocity during the back squat. Furthermore, changes in performance were related to individual-reported conscientiousness. Twelve semiprofessional rugby union players volunteered to participate in the study that consisted of the subjects completing a set of the barbell back squat across 4 conditions (i.e., no-feedback [control], verbal feedback of kinematic information [verbal], visual feedback of kinematic information [visual], and verbal encouragement [encouragement]). In addition, participants completed a questionnaire before the study to assess conscientiousness. Magnitude-based inferences were used to assess differences between conditions, whereas Spearman's rank correlation coefficient was used to assess relationships between conscientiousness and changes in barbell velocity. All 3 forms of feedback showed almost certain improvements in barbell velocity, while differences between interventions were likely to very likely trivial. Changes in barbell velocity showed small to large inverse relationships with conscientiousness. These findings suggest that practitioners should supply kinematic feedback (verbally or visually) or, when technology is not available, provide athletes with encouraging statements while resistance training. Verbal encouragement may be of greatest benefit for individuals who demonstrate low levels of conscientiousness. Given these findings, practitioners are advised to use either technology or verbal encouragement to manipulate acute training outcomes.

Sleep profiles of elite swimmers during different training phases. J Strength Cond Res XX(X): 000-000, 2018-This study aims to describe the sleeping patterns during different training phases in competitive swimmers. Twelve national- and international-level swimmers (3 females and 9 males) were monitored during 4 different phases, consisting of a preparation training phase, a taper phase, a competition phase, and a rest phase. Sleep parameters were assessed using wrist activity monitors and self-reported sleep diaries. There was a moderately higher (d = 0.70-1.00) sleep onset latency during the competition phase compared with taper, train, and rest phases. Trivial to small differences were observed for total sleep time between phases (d = 0.05 0.40). Sleep efficiency was moderately higher (d = 0.60-0.75) in the training and taper phases compared with competition and rest. Restfulness and fragmentation index (FI) were lowest in the rest with differences between phases being small (d = 0.43-0.51) for restfulness and small to moderate (d = 0.43-0.62) for FI. Time in and out of bed was very largely later (d = 1.96-2.34) in rest compared with the other phases. Total nap time was moderately lower in rest (d = 1.13-1.18) compared with the training and competition phases, whereas there was a small difference (d = 0.46) compared with taper. To conclude, while there were trivial to small differences in sleep quantity between phases, there are small to moderate differences in other sleep parameters. Specifically, sleep onset latency was higher during the competition phase. In addition, this study highlights the substantial between-individual variations in sleep responses during different training phases.

Individual muscle hypertrophy and strength responses to high vs. low resistance training frequencies. J Strength Cond Res XX(X): 000-000, 2018-The aim of this short communication was to compare the individual muscle mass and strength gains with high (HF) vs. low (LF) resistance training (RT) frequencies using data from our previous study. We used a within-subject design in which 20 subjects had one leg randomly assigned to HF (5* per week) and the other to LF (2 or 3* per week). Muscle cross-sectional area and 1 repetition maximum were assessed at baseline and after 8 weeks of RT. HF showed a higher 8-week accumulated total training volume (TTV) (p < 0.0001) compared with LF. Muscle cross-sectional area and 1 repetition maximum values increased significantly and similarly for HF and LF protocols (p > 0.05). This short communication highlights that some individuals showed greater muscle mass and strength gains after HF (31.6 and 26.3% of individuals, respectively), other had greater gains with LF (36.8 and 15.8% of individuals, respectively), and even others showed similar responses between HF and LF, regardless of the consequent higher or lower TTV resulted from HF and LF, respectively. Importantly, individual manipulation of RT frequency can improve the intrasubject responsiveness to training, but the effect is limited to each individual's capacity to respond to RT. Finally, individual response to different frequencies and resulted TTV does not necessarily agree between muscle hypertrophy and strength gains.

Examination of physical fitness parameters between professional and amateur Greek soccer players during the transition period. J Strength Cond Res XX(X): 000-000, 2018-The aim of the study was to compare physical fitness parameters between professional and amateur soccer players of different levels. The sample consisted of 381 soccer players divided in 4 experimental groups: first division professional players (n = 115), second division professional players (n = 70), third division semiprofessional players (n = 93), and amateur soccer players (n = 103). Players were tested for several physiological parameters at the end of the transition period. Analysis of variance showed significantly lower body fat and increased maximum oxygen consumption (V[Combining Dot Above]O2max) and velocity of maximum oxygen consumption (vV[Combining Dot Above]O2max) values for first division professional players compared with the other experimental groups (p < 0.05). Similarly, first division professional players showed higher performance during squat jump and countermovement jump test compared with the other experimental groups (p < 0.05). Significant differences on flexibility test were observed between amateur players and the other group (p < 0.05). The results of the study indicated that Greek soccer players at the highest level overcome in almost all the underexamination physiological parameters probably because of less absence from training and better implementation of training programs during the transition period.

AB - Grindstaff, TL, Palimenio, MR, Franco, M, Anderson, D, Bagwell, JJ, and Katsavelis, D. Optimizing between-session reliability for quadriceps peak torque and rate of torque development measures. J Strength Cond Res XX(X): 000-000, 2018 Quadriceps peak torque and rate of torque development (RTD) have relevance for athletic performance and recovery after knee injury. The number of repetitions performed to determine RTD varies between studies, and the associated measurement error has not been established. The purpose of this study was to determine the number of repetitions necessary to optimize the between-session reliability for isometric quadriceps peak torque and RTD measures and to quantify estimates of measurement error. Twenty participants (age = 21.7 +/- 1.7 years, height = 172.5 +/- 16.0 cm, body mass = 76.0 +/- 15.5 kg, and Tegner = 7.1 +/- 1.2) volunteered for this study. Quadriceps isometric peak torque and RTD (50, 100, 150, 200, and 250 ms, and maximum torque) were obtained during 2 testing sessions. Between session reliability was determined using intraclass correlation coefficients (ICC2,k), using the minimal detectable change (MDC) and coefficient of variation (CoV) to quantify measurement error. Between-session reliability was best maximized by using the average of the 3 repetitions with the highest peak torque. Reliability was good for quadriceps peak torque (ICC2,3 = 0.98; MDC = 51.1 N.m; CoV = 38.0%) and ranged from moderate to good for quadriceps RTD measures (ICC2,3 = 0.61 to 0.91; MDC = 264.8 to 738.3 N.m.s; CoV = 38.1-57.9%). Measures of late RTD were less variable and more reliable than early RTD and average RTD measures. These results provide confidence when measuring between-session changes for late RTD measures, but changes in early RTD may be more difficult to distinguish from measurement error. Methods should be used to minimize variability between repetitions and sessions. PMID- 30289875 TI - Identification of Key Genes and Pathways Associated with RUNX1 Mutations in Acute Myeloid Leukemia Using Bioinformatics Analysis. AB - BACKGROUND RUNXl plays a key regulatory role in the process of hematopoiesis and is a common target for multiple chromosomal translocations in human acute leukemia. Mutations of RUNX1 gene can lead to acute leukemia and affect the prognosis of AML patients. We aimed to identify pivotal genes and pathways involved in RUNX1-mutated patients of with acute myeloid leukemia (AML) and to explore possible molecular markers for novel therapeutic targets of the disease. MATERIAL AND METHODS The RNA sequencing datasets of 151 cases of AML were obtained from the Cancer Genome Atlas database. Differentially expressed genes (DEGs) were identified using edgeR of the R platform. PPI (protein-protein interaction) network clustering modules were analyzed with ClusterONE, and the KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway enrichment analyses for modules were performed. RESULTS A total of 379 genes were identified as DEGs. The KEGG enrichment analysis of DEGs showed significantly enriched pathways in cancer, extracellular matrix (ECM)-receptor interaction pathway, and cyclic adenosine monophosphate (cAMP) signaling pathway. The top 10 genes ranked by degree were PRKACG, ANKRD7, RNFL7, ROPN11, TEX14, PRMT8, OTOA, CFAP99, NRXN1, and DMRT1, which were identified as hub genes from the protein-protein interaction network (PPI). Statistical analysis revealed that RUNX1-mutated patients with AML had a shorter median survival time (MST) with poor clinical outcome and an increased risk of death when compared with those without RUNX1 mutations. CONCLUSIONS DEGs and pathways identified in the present study will help understand the molecular mechanisms underlying RUNX1 mutations in AML and develop effective therapeutic strategies for RUNX1-mutation AML. PMID- 30289876 TI - Crafting your scientist brand. AB - That a scientist might shape and cultivate a personal brand is a relatively new concept but one that is finding increasing acceptance in this new age of rapid communications and social media. A key driver is the abrupt rise in well-funded and organized antiscience movements, especially in North America and Europe, such that society now benefits from scientists with strong personal brands and public personas who are willing to engage general audiences. In this sense, branding itself can advance science, the sharing of information, and the promotion of science as a public good. Still another dimension to branding is that it affords an opportunity to mentor younger scientists and helps you to become an important role model for the next generation. There is also a practical side, as today, fewer scientists spend their entire career at a single institution, so owning a strong brand can sometimes create easier paths for transitions and mobility. However, brand cultivation ideally begins in collaboration with your institutional office of communications and is done in a way that is seen as a win for both you and your university or research institution. Described here are some steps to consider when embarking on brand cultivation and how to avoid some of the potential pitfalls. PMID- 30289877 TI - Functional conservation of sequence determinants at rapidly evolving regulatory regions across mammals. AB - Recent advances in epigenomics have made it possible to map genome-wide regulatory regions using empirical methods. Subsequent comparative epigenomic studies have revealed that regulatory regions diverge rapidly between genome of different species, and that the divergence is more pronounced in enhancers than in promoters. To understand genomic changes underlying these patterns, we investigated if we can identify specific sequence fragments that are over enriched in regulatory regions, thus potentially contributing to regulatory functions of such regions. Here we report numerous sequence fragments that are statistically over-enriched in enhancers and promoters of different mammals (which we refer to as 'sequence determinants'). Interestingly, the degree of statistical enrichment, which presumably is associated with the degree of regulatory impacts of the specific sequence determinant, was significantly higher for promoter sequence determinants than enhancer sequence determinants. We further used a machine learning method to construct prediction models using sequence determinants. Remarkably, prediction models constructed from one species could be used to predict regulatory regions of other species with high accuracy. This observation indicates that even though the precise locations of regulatory regions diverge rapidly during evolution, the functional potential of sequence determinants underlying regulatory sequences may be conserved between species. PMID- 30289879 TI - Noise propagation in an integrated model of bacterial gene expression and growth. AB - In bacterial cells, gene expression, metabolism, and growth are highly interdependent and tightly coordinated. As a result, stochastic fluctuations in expression levels and instantaneous growth rate show intricate cross correlations. These correlations are shaped by feedback loops, trade-offs and constraints acting at the cellular level; therefore a quantitative understanding requires an integrated approach. To that end, we here present a mathematical model describing a cell that contains multiple proteins that are each expressed stochastically and jointly limit the growth rate. Conversely, metabolism and growth affect protein synthesis and dilution. Thus, expression noise originating in one gene propagates to metabolism, growth, and the expression of all other genes. Nevertheless, under a small-noise approximation many statistical quantities can be calculated analytically. We identify several routes of noise propagation, illustrate their origins and scaling, and establish important connections between noise propagation and the field of metabolic control analysis. We then present a many-protein model containing >1000 proteins parameterized by previously measured abundance data and demonstrate that the predicted cross-correlations between gene expression and growth rate are in broad agreement with published measurements. PMID- 30289878 TI - Human genetic variation in GLS2 is associated with development of complicated Staphylococcus aureus bacteremia. AB - The role of host genetic variation in the development of complicated Staphylococcus aureus bacteremia (SAB) is poorly understood. We used whole exome sequencing (WES) to examine the cumulative effect of coding variants in each gene on risk of complicated SAB in a discovery sample of 168 SAB cases (84 complicated and 84 uncomplicated, frequency matched by age, sex, and bacterial clonal complex [CC]), and then evaluated the most significantly associated genes in a replication sample of 240 SAB cases (122 complicated and 118 uncomplicated, frequency matched for age, sex, and CC) using targeted sequence capture. In the discovery sample, gene-based analysis using the SKAT-O program identified 334 genes associated with complicated SAB at p<3.5 x 10-3. These, along with eight biologically relevant candidate genes were examined in the replication sample. Gene-based analysis of the 342 genes in the replication sample using SKAT-O identified one gene, GLS2, significantly associated with complicated SAB (p = 1.2 x 10-4) after Bonferroni correction. In Firth-bias corrected logistic regression analysis of individual variants, the strongest association across all 10,931 variants in the replication sample was with rs2657878 in GLS2 (p = 5 x 10-4). This variant is strongly correlated with a missense variant (rs2657879, p = 4.4 x 10-3) in which the minor allele (associated here with complicated SAB) has been previously associated with lower plasma concentration of glutamine. In a microarray-based gene-expression analysis, individuals with SAB exhibited significantly lower expression levels of GLS2 than healthy controls. Similarly, Gls2 expression is lower in response to S. aureus exposure in mouse RAW 264.7 macrophage cells. Compared to wild-type cells, RAW 264.7 cells with Gls2 silenced by CRISPR-Cas9 genome editing have decreased IL1-beta transcription and increased nitric oxide production after S. aureus exposure. GLS2 is an interesting candidate gene for complicated SAB due to its role in regulating glutamine metabolism, a key factor in leukocyte activation. PMID- 30289880 TI - Heritability informed power optimization (HIPO) leads to enhanced detection of genetic associations across multiple traits. AB - Genome-wide association studies have shown that pleiotropy is a common phenomenon that can potentially be exploited for enhanced detection of susceptibility loci. We propose heritability informed power optimization (HIPO) for conducting powerful pleiotropic analysis using summary-level association statistics. We find optimal linear combinations of association coefficients across traits that are expected to maximize non-centrality parameter for the underlying test statistics, taking into account estimates of heritability, sample size variations and overlaps across the traits. Simulation studies show that the proposed method has correct type I error, robust to population stratification and leads to desired genome-wide enrichment of association signals. Application of the proposed method to publicly available data for three groups of genetically related traits, lipids (N = 188,577), psychiatric diseases (Ncase = 33,332, Ncontrol = 27,888) and social science traits (N ranging between 161,460 to 298,420 across individual traits) increased the number of genome-wide significant loci by 12%, 200% and 50%, respectively, compared to those found by analysis of individual traits. Evidence of replication is present for many of these loci in subsequent larger studies for individual traits. HIPO can potentially be extended to high dimensional phenotypes as a way of dimension reduction to maximize power for subsequent genetic association testing.

AB - BACKGROUND: Malalignment of the femoral stem in total hip arthroplasty (THA) can detrimentally affect outcome. Poor preparation of the femur intraoperatively is an important cause of stem malalignment. PURPOSES: The objective was to compare coronal alignment of three different stems using three different broaches. METHODS: Retrospective study of three groups of 60 patients following primary THA via direct anterior approach, by the same surgeon, between January 2015 and January 2016. Each group had a similar designed stem (Corail Depuy, Targos Lepine or Meije Tornier). Groups were matched for age, body mass index, gender, side, neck shaft angle and indications. The significant difference between groups was the broach shape. Broaches for the Corail and Meije stems had a prominent shoulder laterally, while the broach of the Targos stem had a rounded less prominent shape laterally. Coronal alignment was determined radiologically at 2 months. RESULTS: The mean varus was significantly lower for the Targos stems (1.1 degrees +/-0.8) compared to the Corail (2.3 degrees +/-1.5) and Meije stems (1.9 degrees +/-1.2) (p<0.0001). There were significantly less Targos stems with varus greater than 3 degrees (1.7%, n = 1) compared to the Corail (40%, n = 24) and Meije stems (20%, n = 12) (p<0.001). CONCLUSION: A femoral broach with a prominent lateral shoulder when performing a THA via direct anterior approach will increase the risk of varus femoral stem alignment compared to a less laterally prominent broach.

AB - Topical application of Vitamin K1 has been demonstrated to effectively treat papulopustular skin rash, a serious and frequently encountered side effect of Epidermal Growth Factor Inhibitors (EGFRIs). Systemic absorption of vitamin K1 from skin and the resultant consequence of antagonizing EGFRIs anticancer effects jeopardizes the clinical acceptability of this rather effective treatment. The purpose of the present study was to rationally formulate and evaluate the release rate and transdermal absorption of a wide range of Vitamin K1 dermal preparations with a variety of physiochemical properties. A library of 33 formulations with were compounded and tested for Vitamin K1 permeation using hydrophobic membranes and porcine skin mounted in a Fran diffusion cells. Our results demonstrate the lowest diffusion for water-in-oil emulsions, which also demonstrated a negligible transdermal absorption. The statistical analysis showed a significant correlation between in vitro and ex vivo results. While viscosity did not have a significant impact on the diffusion or absorption of vitamin K1, an increase in the lipid content was correlated with an increase in transmembrane diffusion (not with transdermal absorption). Overall, formulation design significantly impacts the release rate and transdermal absorption of vitamin K1, and confirms the possibility of minimal systemic distribution of this vitamin for this specific purpose.

AB - The development of ice-phobic, glass-substrate surfaces is important for many reasons such as poor visibility through the ice-covered windshields of vehicles. The present authors have developed new glass surfaces coated with a silane coupling agent and polypeptides whose amino-acid sequence is identical to a partial sequence of winter flounder antifreeze protein. We have conducted experiments on the freezing of sessile water droplets on the glass surfaces, and measured the droplet temperature, contact angle, contact area and surface roughness. The results show that the supercooling temperature decreased noticeably in the case where a higher concentration solution of polypeptide was used for the coating. The adhesion strength of frozen droplets was lowest in the same case. In addition, we observed many nanoscale humps on the coated surface, which were formed by polypeptide aggregates in the solution. We argue that the combination of the hydrophilic humps and the hydrophobic base surfaces causes water molecules adjacent to the surfaces to have a variety of orientations in that plane, even after the ice layer started to grow. This then induces a misfit of water-molecule spacing in the ice layers and consequent formation of fragile polycrystalline structure. This explains the lower values of ice adhesion strength and supercooling enhancement in the cases of the polypeptide-coated glass plates.

AB - BACKGROUND: Persons with human immunodeficiency virus (HIV) who get and keep a suppressed viral load are unlikely to transmit HIV. Simple, practical interventions to help achieve HIV viral suppression that are easy and inexpensive to administer in clinical settings are needed. We evaluated whether a brief video containing HIV-related health messages targeted to all patients in the waiting room improved treatment initiation, medication adherence, and retention in care. METHODS AND FINDINGS: In a quasi-experimental trial all patients (N = 2,023) attending two HIV clinics from June 2016 to March 2017 were exposed to a theory based, 29-minute video depicting persons overcoming barriers to starting treatment, taking medication as prescribed, and keeping medical appointments. New prescriptions at index visit, HIV viral load test results, and dates of return visits were collected through review of medical records for all patients during the 10 months that the video was shown. Those data were compared with the same variables collected for all patients (N = 1,979) visiting the clinics during the prior 10 months (August 2015 to May 2016). Among patients exposed to the video, there was an overall 10.4 percentage point increase in patients prescribed treatment (60.3% to 70.7%, p< 0.01). Additionally, there was an overall 6.0 percentage point improvement in viral suppression (56.7% to 62.7%, p< 0.01), however mixed results between sites was observed. There was not a significant change in rates of return visits (77.5% to 78.8%). A study limitation is that, due to the lack of randomization, the findings may be subject to bias and secular trends. CONCLUSIONS: Showing a brief treatment-focused video in HIV clinic waiting rooms can be effective at improving treatment initiation and may help patients achieve viral suppression. This feasible, low resource-reliant video intervention may be appropriate for adoption by other clinics treating persons with HIV. TRIAL REGISTRATION: http://www.ClinicalTrials.gov (NCT03508310).

AB - Proteins, metabolites, and 16S rRNA measurements were used to examine the community structure and functional relationships within a cellulose degrading anaerobic bioreactor. The bioreactor was seeded with bovine rumen fluid and operated with a 4 day hydraulic retention time on cellulose (avicel) as sole carbon and energy source. The reactor performance and microbial community structure was monitored during the establishment of the cellulose-degrading community. After stable operation was established in the bioreactor, the mixing intensity was increased in order to investigate the effect of a physical disruption of the microbial community structure. Finally, the original conditions were re-established to understand the stability of the microbial community after a perturbation. All factors measured were found to be inter-correlated during these three distinct phases of operation (establishment, perturbation and re establishment). In particular, the return of community structure and function to pre-perturbed conditions suggests that propionate fermentation and acetate utilization were the explanatory factors for community establishment and re establishment. PMID- 30289886 TI - A reassessment of global antenatal care coverage for improving maternal health using sub-Saharan Africa as a case study. AB - BACKGROUND: Antenatal period is an opportunity for reaching pregnant women with vital interventions. In fact, antenatal care (ANC) coverage was an indicator for assessing progress towards the Millennium Development Goals. This paper applies a novel index of service coverage using ANC, which accounts for every ANC visit. An index of service coverage gap is also proposed. These indices are additively decomposable by population groups and they are sensitive to the receipt of more ANC visits below a defined threshold. These indices have also been generalised to account for the quality of services. METHODS: Data from recent rounds of the Demographic and Health Survey (DHS) are used to reassess ANC service coverage in 35 sub-Saharan African countries. An index of ANC coverage was estimated. These countries were ranked, and their ranks are compared with those based on attaining at least four ANC visits (ANC4+). FINDINGS: The index of ANC coverage reflected the level of service coverage in countries. Further, disparities exist in country ranking as some countries, e.g. Cameroon, Benin Republic and Nigeria are ranked better using the ANC4+ indicator but poorly using the proposed index. Also, Rwanda and Malawi are ranked better using the proposed index. CONCLUSION: The proposed ANC index allows for the assessment of progressive realisation, rooted in the move towards universal health coverage. In fact, the index reflects progress that countries make in increasing service coverage. This is because every ANC visit counts. Beyond ANC coverage, the proposed index is applicable to assessing service coverage generally including quality education. PMID- 30289887 TI - The effect of modified locking methods and suture materials on Zone II flexor tendon repair-An ex vivo study. AB - The failure rate of intrasynovial tendon repair is high due to substantial elongation at the repair site and to the development of adhesions between the tendon's surface and the surrounding digital sheath. To minimize these complications, we sought to reduce the incidence of gapping and to facilitate the initiation of early motion by improving the time zero structural properties of repair. The Winters-Gelberman 8-strand repair technique was modified by adding surface lock loops and by using Fiberwire suture material. Forty-eight canine flexor digitorum profundus tendons were transected and repaired with one of three 8-strand techniques (Pennington modified Kessler, half hitch loops, or surface locking Kessler) using either 3-0 Supramid or 4-0 Fiberwire suture. Biomechanical testing was performed to determine the physiologic and failure mode properties of the repairs. The surface locking Kessler technique improved repair maximum load, load necessary to create a 2 mm repair site gap, and yield force compared to the modified Kessler and half hitch loop techniques. Fiberwire suture improved maximum load, the load necessary to create a 2 mm repair site gap, stiffness, and yield force compared to Supramid suture. Failure occurred by both suture pull out and by suture breakage in the modified Kessler, Supramid suture repair group. Failure occurred consistently by suture breakage in the surface locking Kessler, Supramid suture repair group. These results reveal that a novel locking Kessler repair is significantly stronger than the current state-of-the art flexor tendon suture repair technique. The use of a surface locking Kessler technique with Fiberwire suture markedly improves the mechanical properties of intrasynovial tendon repair by reducing the risk of post-operative gapping and rupture. PMID- 30289889 TI - Habitat complexity and benthic predator-prey interactions in Chesapeake Bay. AB - In Chesapeake Bay, the soft-shell clam Mya arenaria (thin-shelled, deep burrowing) exhibits population declines when predators are active, and it persists at low densities. In contrast, the hard clam Mercenaria mercenaria (thick-shelled, shallow-burrowing) has a stable population and age distribution. We examined the potential for habitat and predators to control densities and distributions of bivalves in a field caging experiment (Mya only) and laboratory mesocosm experiments (both species). In the field, clams exposed to predators experienced 76.3% greater mortality as compared to caged individuals, and blue crabs were likely responsible for most of the mortality of juvenile Mya. In mesocosm experiments, Mya had lower survival in sand and seagrass than in shell hash or oyster shell habitats. However, crabs often missed one or more prey items in seagrass, shell, and oyster shell habitats. Predator search times and encounter rates declined when prey were at low densities, likely due to the added cost of inefficient foraging; however, this effect was more pronounced for Mya than for Mercenaria. Mercenaria had higher survival than Mya in mesocosm experiments, likely because predators feeding on Mercenaria spent less time foraging than those feeding on Mya. Mya may retain a low-density refuge from predation even with the loss of structurally complex habitats, though a loss of habitat refuge may result in clam densities that are not sustainable. A better understanding of density-dependent predator-prey interactions is necessary to prevent loss of food-web integrity and to conserve marine resources. PMID- 30289888 TI - Species identity matters when interpreting trophic markers in aquatic food webs. AB - In aquatic systems, food web linkages are often assessed using diet contents, stable isotope ratios, and, increasingly, fatty acid composition of organisms. Some correlations between different trophic metrics are assumed to be well supported; for example, particular stable isotope ratios and fatty acids seem to reflect reliance on benthic or pelagic energy pathways. However, understanding whether the assumed correlations between different trophic metrics are coherent and consistent across species represents a key step toward their effective use in food web studies. To assess links among trophic markers, we compared relationships between major diet components, fatty acids, and stable isotope ratios in three fishes: yellow perch (Perca flavescens), round goby (Neogobius melanostomus), and spottail shiner (Notropis hudsonius) collected from nearshore Lake Michigan. Yellow perch and spottail shiner are native in this system, while round goby are a relatively recent invader. We found some evidence for agreement between different trophic metrics, especially between diet components, n-3:n-6 fatty acid ratios, and stable isotope ratios (delta13C and delta15N). However, we also observed significant variation in observed relationships among markers and species, potentially due to taxonomic variation in the specific diet items consumed (e.g., chydorid microcrustaceans and Dreissena mussels) and species specific biochemical processes. In many of these latter cases, the invasive species differed from the native species. Understanding the effects of taxonomic variation on prey and predator signatures could significantly improve the usefulness of fatty acids in food web studies, whereas diet contents and stable isotopes appear to be reliable indicators of trophic niche in aquatic food webs. PMID- 30289890 TI - Did you choose appropriate tracer for retrograde tracing of retinal ganglion cells? The differences between cholera toxin subunit B and Fluorogold. AB - Cholera toxin subunit B (CTB) and Fluorogold(FG) are two widely utilized retrograde tracers to assess the number and function of retinal ganglion cells (RGCs). However, the relative advantages and disadvantages of these tracers remain unclear, which may lead to their inappropriate application. In this study, we compared these tracers by separately injecting the tracer into the superior Colliculi (SC) in rats, one or 2 weeks later, the rats were sacrificed, and their retinas, brains, and optic nerves were collected. From the first to second week, FG displayed a greater number of labeled RGCs and a larger diffusion area in the SC than CTB; The number of CTB labeled RGCs and the diffusion area of CTB in the SC increased significantly, but there was no distinction between FG; Furthermore, CTB exhibited more labeled RGC neurites and longer neurites than FG, but no difference was evident between the same trace; The optic nerves labeled using CTB were much clearer than those labeled using FG. In conclusion, both CTB and FG can be used for the retrograde labeling of RGCs in rats at 1 or 2 weeks. FG achieves retrograde labeling of a greater number of RGCs than CTB, whereas CTB better delineates the morphology of RGCs. Furthermore, CTB seems more suitable for retrograde labeling of some small, non-image forming nuclei in the brain to which certain RGC subtypes project their axons. PMID- 30289891 TI - A quantile regression forest based method to predict drug response and assess prediction reliability. AB - Drug response prediction is a critical step for personalized treatment of cancer patients and ultimately leads to precision medicine. A lot of machine-learning based methods have been proposed to predict drug response from different types of genomic data. However, currently available methods could only give a "point" prediction of drug response value but fail to provide the reliability and distribution of the prediction, which are of equal interest in clinical practice. In this paper, we proposed a method based on quantile regression forest and applied it to the CCLE dataset. Through the out-of-bag validation, our method achieved much higher prediction accuracy of drug response than other available tools. The assessment of prediction reliability by prediction intervals and its significance in personalized medicine were illustrated by several examples. Functional analysis of selected drug response associated genes showed that the proposed method achieves more biologically plausible results. PMID- 30289892 TI - The TLR1 gene is associated with higher protection from leprosy in women. AB - Leprosy is an infectious disease with a complex genetic and immunological background. Polymorphisms in genes that encode cytokines and receptors involved in the immune response, such as the Toll-like receptor 1 (TLR1), may be associated with disease risk. We hypothesized that polymorphisms in innate immunity genes confer susceptibility to leprosy that differs between women and men. In this study, we investigate sex differences in the association between a single nucleotide polymorphism (SNP) in TLR1 and Nucleotide-binding oligomerization domain containing 2 (NOD2) genes and leprosy susceptibility in 256 clinically classified leprosy patients and 233 control subjects in a Brazilian population. Our results showed no association between the SNP rs8057341 in NOD2 and leprosy in this population. However, the heterozygous genotype of the TLR1 SNP (rs4833095) showed a statistically significant association in women (OR = 0.54, P = 0.02). Our findings suggest that the TLR1 polymorphism was associated with an increased protection from leprosy in women. PMID- 30289893 TI - Design and evaluation of selective butyrylcholinesterase inhibitors based on Cinchona alkaloid scaffold. AB - This paper describes the synthesis and anticholinesterase potency of Cinchona based alkaloids; ten quaternary derivatives of cinchonines and their corresponding pseudo-enantiomeric cinchonidines. The quaternization of quinuclidine moiety of each compound was carried out with groups diverse in their size: methyl, benzyl and differently meta- and para-substituted benzyl groups. All of the prepared compounds reversibly inhibited human butyrylcholinesterase and acetylcholinesterase with Ki constants within nanomolar to micromolar range. Five cinchonidine derivatives displayed 95-510 times higher inhibition selectivity to butyrylcholinesterase over acetylcholinesterase and four were potent butyrylcholinesterase inhibitors with Ki constants up to 100 nM, of which N-para-bromobenzyl cinchonidinium bromide can be considered a lead for further modifications and optimizations for possible use in the treatment of neurodegenerative diseases. PMID- 30289895 TI - Investigating the effect of wearing the hijab: Perception of facial attractiveness by Emirati Muslim women living in their native Muslim country. AB - The Hijab and other forms of Islamic veiling are important social, cultural, and religious symbols that are central to the identity of millions of Muslim women across the world. However, despite the large body of literature that exists on the political and socio-cultural aspects of Islamic veiling, little is known about how the appearance of women wearing the hijab is perceived by other Muslim women within their native Muslim country. To throw light on this important issue, the current study focussed on the effects of the hijab on female facial attractiveness perceived by practising Muslim Emirati women living in their native Muslim country (the United Arab Emirates) who themselves wore the hijab as everyday attire. Participants were shown frontal-head images of women in three different conditions: covered (heads fully covered by the hijab except for the face), partially covered (heads fully covered by the hijab except for the face and the hair around the forehead) and uncovered (heads with no covering). The findings showed that faces in images where heads were covered and partially covered by the hijab were rated as equally attractive but both were rated as significantly less attractive than faces in images where heads were uncovered. These findings suggest that, even for practising Muslim Emirati females living in their native Muslim country for whom wearing the hijab is a normal aspect of everyday life, perception of facial attractiveness is compromised by wearing this garment. We argue that this effect of wearing the hijab is not consistent with a preference for one's own cultural group (cultural endogamy) and may, instead, occur because wearing a hijab occludes external features, such as hair and ears, which normally contribute to the perception of human facial attractiveness. In sum, while wearing the hijab may be dominated by male attitudes towards suppressing female attractiveness towards males, the findings from this study suggest that female Muslims too perceive the negative influence of wearing the hijab on female facial attractiveness. PMID- 30289894 TI - The impact of heat and impaired kidney function on productivity of Guatemalan sugarcane workers. AB - BACKGROUND: Climate change has implications for human health and productivity. Models suggest that heat extremes affect worker health, reduce labor capacity, and commodity supply. Chronic health conditions are on the rise internationally. However there is a paucity of direct empirical evidence relating increasing temperatures to both agricultural worker health and productivity. METHODS AND FINDINGS: We evaluated the relationship between temperature exposure, kidney function, and two measures of productivity-tons of commodity produced and job attrition, of 4,095 Guatemalan sugarcane cutters over a 6-month harvest. We used distributed lag non-linear models to evaluate associations between wet bulb globe temperature (WBGT) and productivity of workers with normal or impaired kidney function. The cumulative effect of exposure to a max WBGT of 34 degrees C was 1.16 tons (95% CI: -2.87, 0.54) less sugarcane cut over the next five days by workers with impaired kidney function, compared to exposure to 29 degrees C. Impaired kidney function was associated with premature workforce attrition. Workers starting the harvest season with impaired kidney function were more than twice as likely to leave employment (HR: 2.92, 95% CI: 1.88, 4.32). CONCLUSIONS: Heat extremes may be associated with loss of agricultural worker productivity and employment, especially among those with impaired kidney function. Agricultural workers who develop health conditions, such as kidney disease, are particularly vulnerable in the face of climate change and increasing heat extremes. The resultant loss of employment and productivity has significant implications for global commodity supplies. PMID- 30289897 TI - Security and efficiency enhancement of an anonymous three-party password authenticated key agreement using extended chaotic maps. AB - Recently, Lu et al. claimed that Xie et al.'s three-party password-authenticated key agreement protocol (3PAKA) using chaotic maps has three security vulnerabilities; in particular, it cannot resist offline password guessing attack, Bergamo et al.'s attack and impersonation attack, and then they proposed an improved protocol. However, we demonstrate that Lu et al.'s attacks on Xie et al.'s scheme are unworkable, and their improved protocol is insecure against stolen-verifier attack and off-line password guessing attack. Furthermore, we propose a novel scheme with enhanced security and efficiency. We use formal verification tool ProVerif, which is based on pi calculus, to prove security and authentication of our scheme. The efficiency of the proposed scheme is higher than other related schemes. PMID- 30289896 TI - Proportion of adults in the general population of Stockholm County who want gender-affirming medical treatment. AB - The number of patients presenting for care at gender clinics is increasing, yet the proportion of adults in the general population who want gender-affirming medical treatment remains essentially unknown. We measured the wish for cross-sex hormones or gender-affirming surgery, as well as other aspects of gender incongruence, among the general adult population of Stockholm County, Sweden. A population-representative sample of 50,157 Stockholm County residents ages 22 and older comprise the Stockholm Public Health Cohort. They were enrolled in 2002, 2006, and 2010 and followed-up in roughly 4-year intervals, with questions on health, lifestyle and social characteristics. In 2014, participants received the item "I would like hormones or surgery to be more like someone of a different sex." Two additional items concerned other aspects of gender incongruence: "I feel like someone of a different sex", and "I would like to live as or be treated as someone of a different sex." Each item had four answer options ("Not at all correct", "Somewhat or occasionally correct", "Quite correct", and "Absolutely correct"). For each item, any of the three affirmative answer choices were considered as some level of agreement. Calibration weights were used to estimate population-representative rates with 95% confidence intervals. The desire for cross-sex hormones or surgery was reported by 0.5% (95% CI, 0.4%-0.7%) of participants. Feeling like someone of a different sex was reported by 2.3% (95% CI, 2.1%-2.6%). Wanting to live as or be treated as a person of another sex was reported by 2.8% (95% CI, 2.4%-3.1%). These findings greatly exceed estimates of the number of patients receiving gender-affirming medical care. Clinicians must be prepared to recognize and care for patients experiencing discomfort due to gender incongruence and those who would like gender-affirming medical treatment. PMID- 30289899 TI - Forensic analysis of Turkish elections in 2017-2018. AB - With a majority of 'Yes' votes in the Constitutional Referendum of 2017, Turkey continued its drift towards an autocracy. By the will of the Turkish people, this referendum transferred practically all executive power to president Erdogan. However, the referendum was confronted with a substantial number of allegations of electoral misconducts and irregularities, ranging from state coercion of 'No' supporters to the controversial validity of unstamped ballots. Here we report the results of an election forensic analysis of recent Turkish elections to clarify to what extent it is plausible that these voting irregularities were present and able to influence the outcome of the referendum. We apply statistical forensics tests to identify the specific nature of the alleged electoral malpractices. In particular, we test whether the data contains fingerprints for ballot stuffing (submission of multiple ballots per person during the vote) and voter rigging (coercion and intimidation of voters). Additionally, we perform tests to identify numerical anomalies in the election results. For the 2017 Constitutional Referendum we find systematic and highly significant statistical support for the presence of both ballot stuffing and voter rigging. In 11% of stations we find signs for ballot stuffing with a standard deviation (uncertainty of ballot stuffing probability) of 2.7% (4 sigma event). Removing such ballot-stuffing characteristic anomalies from the data would tip the overall balance from 'No' to a majority of 'Yes' votes. The 2017 election was followed by early elections in 2018 to directly vote for a new president who would now be head of state and government. We find statistical irregularities in the 2018 presidential and parliamentary elections similar in size and direction to those in 2017. These findings validate that our results unveil systematic and potentially even fraudulent biases that require further attention in order to combat electoral malpractices. PMID- 30289898 TI - Expected changes in obesity after reformulation to reduce added sugars in beverages: A modeling study. AB - BACKGROUND: Several strategies have been proposed to reduce the intake of added sugars in the population. In Mexico, a 10% sugar-sweetened beverages (SSBs) tax was implemented in 2014, and the implementation of other nutritional policies, such as product reformulation to reduce added sugars, is under discussion. WHO recommends that all individuals consume less than 10% of their total energy intake (TEI) from added sugars. We propose gradually reducing added sugars in SSBs to achieve an average 10% consumption of added sugars in the Mexican population over 10 years and to estimate the expected impact of reformulation in adult body weight and obesity. METHODS AND FINDINGS: Baseline consumption for added sugars and SSBs, sex, age, socioeconomic status (SES), height, and weight for Mexican adults were obtained from the 2012 Mexico National Health and Nutrition Survey (ENSANUT). On average, 12.6% of the TEI was contributed by added sugars; we defined a 50% reduction in added sugars in SSBs over 10 years as a reformulation target. Using a dynamic weight change model, sugar reductions were translated into individual expected changes in body weight assuming a 43% caloric compensation and a 2-year lag for the full effect of reformulation to occur. Results were stratified by sex, age, and SES. Twelve years after reformulation, the TEI from added sugars is expected to decrease to 10%, assuming no compensation from added sugars; 44% of the population would still be above WHO recommendations, requiring further sugar reductions to food. Body weight could be reduced by 1.3 kg (95% CI -1.4 to -1.2) in the adult population, and obesity could decrease 3.9 percentage points (pp; -12.5% relative to baseline). Our sensitivity analyses suggest that the impact of the intervention could vary from 0.12 kg after 6 months to 1.52 kg in the long term. CONCLUSIONS: Reformulation to reduce added sugars in SSBs could produce large reductions in sugar consumption and obesity in the Mexican adult population. This study is limited by the use of a single dietary recall and by data collected in all seasons except summer; still, these limitations should lead to conservative estimates of the reformulation effect. Reformulation success could depend on government enforcement and industry and consumer response, for which further research and evidence are needed. PMID- 30289900 TI - Knowledge gaps among South African healthcare providers regarding the prevention of neonatal group B streptococcal disease. AB - OBJECTIVE: To evaluate obstetric healthcare provider knowledge regarding the prevention of group B streptococcal disease in South African infants. METHODS: Questionnaires exploring knowledge, attitudes and beliefs around group B streptococcal prevention were administered to consenting doctors and maternity nurses in a tertiary academic hospital. Qualitative assessments (focus groups) were undertaken with junior doctors and nurses. RESULTS: 238 participants completed the questionnaire: 150 (63.0%) doctors and 88 (37.0%) nurses. Overall, 22.7% of participants correctly identified the risk-based prevention protocol recommended at this hospital. Most doctors (68.0%) and nurses (94.3%) could not correctly list a single risk factor. A third of doctors did not know the correct antibiotic protocols, and most (80.0%) did not know the recommended timing of antibiotics in relation to delivery. Focus group discussions highlighted the lack of knowledge, awareness and effective implementation of protocols regarding disease prevention. CONCLUSIONS: Our study highlighted knowledge gaps on the risk based prevention strategy in a setting which has consistently reported among the highest incidence of invasive group B streptococcal disease globally. In these settings, education and prioritization of the risk-based intrapartum antibiotic strategy is warranted, but an alternative vaccine-based strategy may prove more effective in preventing invasive group B streptococcal disease in the long-term. PMID- 30289901 TI - Human-modified biogeographic patterns and conservation in game birds: The dilemma of the black francolin (Francolinus francolinus, Phasianidae) in Pakistan. AB - The ever-increasing human-mediated wildlife reshuffling is raising concern for the conservation of biodiversity. The loss of biological distinctiveness among regions lessens the genetic diversity and consequently the evolutionary potential of local biotas to tackle present-day global change and human disturbance. This process may be sometimes cryptic unless investigated by means of a molecular approach. In this respect, game birds are a paradigmatic case. The black francolin (Francolinus francolinus, Phasianidae) is a medium-sized galliform whose distribution range stretches from Cyprus to the Gulf of Bengal. Six morphologic subspecies are known, with three of which occurring in Pakistan, where the species is heavily hunted and used as pet for chirping competitions. We genotyped 98 samples (feathers) at both the entire mitochondrial DNA Control Region gene and nine microsatellite loci to get a deeper insight into the genetic diversity of the black francolin in Pakistan in order to offer cogent recommendations for its conservation management. We identified several mtDNA lineages that were consistent with the currently described subspecies/taxonomy whose pattern of co-occurrence is compatible with the geological history and the faunal movement routes of the region under study. However, the biparentally inherited microsatellites returned a quite discordant picture of an extensive, sex-biased genetic mixing due to the intensive relocations of already overharvested male individuals for chirping competitions. Our results indicated that the genetic integrity of the black francolin in Pakistan could be seriously at risk and call for monitoring and limiting its trade other than enhancing the public awareness of the importance of local biodiversity resources. PMID- 30289903 TI - Willingness-to-pay for sustainable beer. AB - Breweries across the country are investing in energy efficient and low-carbon brewing practices. Drawing insights from the sustainable consumption and ecological economics literature, this analysis evaluates whether consumers are willing to pay more for sustainable beer and what predicts the value of the premium. Based on a survey of beer consumers from across the U.S. that contained one of two willingness-to-pay exercises, we evaluate what respondent attributes are associated with a higher willingness-to-pay for sustainably brewed beer. We find that the majority of beer consumers are willing to pay more for sustainable beer. Consumers who are prepared to pay a premium tend to already pay more per unit of beer, are more aware of their purchasing behavior and the manner in which their consumption patterns may affect the environment, and pursue lifestyles based on professional advancement, helping the environment, and helping other causes. PMID- 30289902 TI - Identification of the novel deletion-type PML-RARA mutation associated with the retinoic acid resistance in acute promyelocytic leukemia. AB - All-trans retinoic acid (ATRA) and arsenic trioxide (ATO) are essential for acute promyelocytic leukemia (APL) treatment. It has been reported that mutations in PML-RARA confer resistance to ATRA and ATO, and are associated with poor prognosis. Although most PML-RARA mutations were point mutations, we identified a novel seven amino acid deletion mutation (p.K227_T233del) in the RARA region of PML-RARA in a refractory APL patient. Here, we analyzed the evolution of the mutated clone and demonstrated the resistance of the mutated clone to retinoic acid (RA). Mutation analysis of PML-RARA was performed using samples from a chemotherapy- and ATRA-resistant APL patient, and the frequencies of mutated PML RARA transcript were analyzed by targeted deep sequencing. To clarify the biological significance of the identified PML-RARA mutations, we analyzed the ATRA-induced differentiation and PML nuclear body formation in mutant PML-RARA transduced HL-60 cells. At molecular relapse, the p.K227_T233del deletion and the p.R217S point-mutation in the RARA region of PML-RARA were identified, and their frequencies increased after re-induction therapy with another type of retinoiec acid (RA), tamibarotene. In deletion PML-RARA-transduced cells, the CD11b expression levels and NBT reducing ability were significantly decreased compared with control cells and the formation of PML nuclear bodies was rarely observed after RA treatment. These results indicate that this deletion mutation was closely associated with the disease progression during RA treatment.

AB - Based on a survey, the following study investigates opinions and also usage patterns relating to the ResearchGate social networking site for scientists and researchers. The survey consisted of 19 questions and was conducted online with 695 scientists from the disciplines of physics, biology, medicine, and neuroscience. Amongst other issues, the research questions concerned how much time and effort the interviewees expended on ResearchGate, what added value they perceived in using the site, the extent to which social aspects influence use, how participants planned to use the platform in future, and what role ResearchGate's own metric, the RG score, played for the scientists. In addition, we discuss which of the factors of age, sex, origin, and scientific discipline have a decisive influence on the responses of the interviewees and which are of no statistical significance The results clearly show that the origin of the participants is frequently decisive, but that the remaining factors also have a considerable influence on the responses for more than 25% of the questions.

AB - OBJECTIVE: To investigate the effect of the number of coaching sessions after communication skills training on the medical communicative performance of oncologists in clinical practice. METHODS/DESIGN: The training, consisting of a workshop and one (control group) vs. four (intervention group) sessions of individual coaching, was evaluated in a randomized controlled trial. Eligible participants included physicians working in any setting where patients with oncological diseases were treated. Real medical consultations were video recorded at three time points: before the workshop (t0), after the workshop (t1) and after completion of coaching (t2). The 1.5-day workshop was based on role-playing in small groups; in the coaching sessions, the videos recorded at t1 were analyzed in detail by both the trainer and the physician. The coaching sessions were manualized and based on the physician's learning goals. The primary hypothesis was that the intervention group would improve to a higher extent than the control group, as assessed by external raters using rating scales specially developed for this project. Physicians were stratified for sex and setting and randomized by an independent statistician. The group assignment was revealed for physicians and trainers at the end of the workshop, while the raters were blinded to group assignments and assessment points. RESULTS: A total of 72 physicians participated in one of 8 workshops and could be allocated to either the control or intervention group. The intervention group showed a statistically significant improvement (ES d = 0.41, p<.01) in the All items domain of the rating scales between t1 and t2 and showed a significant advantage compared with the CG (ES = .41, p = .04). The impact on diverse specified skills was heterogeneous; a larger sample is necessary for more detailed analysis. CONCLUSIONS: The training achieved some observable and significant changes in the communicative behavior of oncologists in clinical practice. The four coaching sessions showed some significant advantages compared to the single coaching session. Considerable effort is necessary to achieve sustained changes in communication in clinical every-day practice. Thus, our coaching concept is a promising method for this purpose.

AB - This study aimed to compare the components of force-velocity (F-V) and power velocity (P-V) profiles and the mechanical effectiveness of force application (or force ratio-RF) among various sled-towing loads during the entire acceleration phase of a weighted sled sprint. Eighteen sprinters performed four 50-m sprints in various conditions: unloaded; with a load corresponding to 20% of the athlete's body mass (BM); with a load of 30% BM; and with a load of 40% BM. Data were collected with five video cameras, and the images were digitised to obtain velocity from the derivation of the centre-of-mass position. F-V and P-V components and RF were estimated from sprinting velocity-time data for each load using a validated method that is based on an inverse dynamic approach applied to the sprinter's centre-of-mass (it models the horizontal antero-posterior and vertical ground reaction force components) and requires only measurement of anthropometric and spatiotemporal variables (body mass, stature and instantaneous position or velocity during the acceleration phase). The theoretical maximal velocity decreased with load compared with the unloaded condition (for 20% BM: 6%, effect size (ES) = 0,38; for 30% BM: -15%, ES = 1.02; for 40% BM: -18%, ES = 1.10). The theoretical maximal horizontal force (F0) and maximal power were not different among conditions. However, power at the end of the acceleration phase increased with load (40% BM vs 0%: 72%; ES = 2.73) as well as the maximal mechanical effectiveness (12%; ES = 0.85). The linear decrease in RF was different between 30 or 40% BM and the unloaded condition (-23%; ES = 0.74 and 0.66). Better effectiveness may be developed with 40% BM load at the beginning of the acceleration and with the various load-induced changes in the components of the F-V and P-V relationships, allowing a more accurate determination of optimal loading conditions for maximizing power.

AB - Human killing is the decisive and most critical expression of human-leopard conflict and needs to be addressed sensitively to maintain local support for leopard conservation in India. This research was undertaken to investigate the ecological aspects of human killing and injury, spatial characteristic and pattern of such sites, temporal and seasonal trends of attacks and perception of local communities towards leopard in the Indian Himalayan region (IHR). We surveyed two sites i) Pauri Garhwal in the western part and ii) North Bengal (Dooars) in the eastern part of IHR, compiled secondary data on human-leopard conflict records and made field visits to (N = 101) conflict sites. We also conducted (N = 186) semi-structured questionnaire surveys in each of the sites to assess perception of local communities towards leopard. We analyzed the conflict data using rare events model in a binary logistic regression framework to understand spatial patterns of such incidents for Pauri Garhwal and North Bengal. The average number of injuries and deaths to leopard attacks in Pauri was estimated to be 11 (SE 1.13) and 3 (SE 0.6) per year between 2006-2016 whereas in North Bengal it was estimated to be 70 (SE 9.2) and 1.6 (SE 0.3) respectively between 2004-2016. About 97% of the leopard attacks in North Bengal and 60% of the leopard attacks in Pauri resulted in human injuries. Majority of the leopard attack victims in Pauri were children and young people, whereas in North Bengal it was middle aged tea estate workers. Attack on humans in Pauri were recorded mostly near areas with dense scrub cover whereas in North Bengal it was reported within tea-estates. The percentage of human deaths to leopard attacks in Pauri were higher (40%) compared to a mere (3%) in North Bengal. Forty-one percent of respondents in Pauri and 75% in North Bengal were positive towards presence and conservation of leopard. A predictive risk map revealed central and northern regions of Pauri Garhwal and protected areas, peripheral areas in central and south-western dooars (North Bengal) as high "human-leopard conflict risk zones". This analytical procedure can be adopted in other sites to identify potential human-carnivore conflict risk zones.

AB - The aim of this study was to determine the predictors of post-traumatic enophthalmos (PE) in relation to the internal orbital changes following pure orbital blowout fractures. The design was a 10-year retrospective cross-sectional study analysing 629 medical records and computed tomography (CT) data of patients with orbital fractures from January 2008 to January 2017. Demographic, etiology, co-morbidity and clinical characteristics were obtained from the medical records. Assessment of the PE, fracture site and size, intraorbital structures and muscle change were performed using the Digital Imaging and Communications in Medicine (DICOM) viewer software, OsiriX v5.8.2. Of the 629 patients with orbital fractures, 87 were pure orbital blowout fractures. Demographic pattern showed that males outnumbered females in the series, with male: female ratio of 5.7:1. The mean age was 37.2 +/- 14.7 and the main etiology was motor vehicle accident. Orbital floor fracture was the most common fracture location (67.8%). The involvement of the posterior ledge and inferior orbital fissure showed statistical significant difference with PE (Fisher's exact test, p = 0.03). Binary logistic regression showed that after controlling for age, patients with fracture size of more than 150 mm2 had three times the odds of sustaining a PE, (adjusted odds ratio (AOR) = 3.01 (95% CI 1.17-7.92). Fracture size larger than 150 mm2 was a radiological predictor of PE. Additional research investigating further on the role of concurrent fracture of the posterior ledge and inferior orbital fissure is advocated.

AB - Sorghum (Sorghum bicolor) is a drought tolerant crop, which is being developed as a bioenergy feedstock. The monolignol biosynthesis pathway is a major focus for altering the abundance and composition of lignin. Caffeoyl coenzyme-A O methyltransferase (CCoAOMT) is an S-adenosyl methionine (SAM)-dependent O methyltransferase that methylates caffeoyl-CoA to generate feruloyl-CoA, an intermediate required for the biosynthesis of both G- and S-lignin. SbCCoAOMT was overexpressed to assess the impact of increasing the amount of this enzyme on biomass composition. SbCCoAOMT overexpression increased both soluble and cell wall-bound (esterified) ferulic and sinapic acids, however lignin concentration and its composition (S/G ratio) remained unaffected. This increased deposition of hydroxycinnamic acids in these lines led to an increase in total energy content of the stover. In stalk and leaf midribs, the increased histochemical staining and autofluorescence in the cell walls of the SbCCoAOMT overexpression lines also indicate increased phenolic deposition within cell walls, which is consistent with the chemical analyses of soluble and wall-bound hydroxycinnamic acids. The growth and development of overexpression lines were similar to wild-type plants. Likewise, RNA-seq and metabolite profiling showed that global gene expression and metabolite levels in overexpression lines were also relatively similar to wild type plants. Our results demonstrate that SbCCoAOMT overexpression significantly altered cell wall composition through increases in cell wall associated hydroxycinnamic acids without altering lignin concentration or affecting plant growth and development. PMID- 30289913 TI - Isolation and exploitation of minority: Game theoretical analysis. AB - We investigate various group-size distributions occurring in a situation where each group's resource is exposed to appropriation by other groups. The amount of appropriation depends on the size difference between groups. Our work focuses on the cases where the entire community isolates a small group or even an individual to maximize its gain. While people's basic motivation to form a group can be understood based on the group-size effect on multiplying a collective asset, sensitive factors that induce a asymmetric group distribution are the group efficiency and the ratio of secured assets to assets pending in a competition. We show that social rejection to a minor group may occur when the group efficiency is relatively low and their asset is severely exposed to possible appropriation. PMID- 30289911 TI - Dietary polysaccharide-rich extract from Eucheuma cottonii modulates the inflammatory response and suppresses colonic injury on dextran sulfate sodium induced colitis in mice. AB - Inflammatory bowel disease (IBD) is a known medical burden in most developed countries and a significant cause of morbidity. The IBD label includes Crohn's disease (CD) and ulcerative colitis (UC). Pharmacological and surgical intervention are the two main management approaches for IBD. Some drugs have been developed for IBD therapy, but accessibility is limited due to high costs. Furthermore, these agents have demonstrated inactivity over long-term treatment courses. Therefore, an urgent need is present for new treatment options that are safe, able to sustain clinical remission, and improve mucosal gut healing. Seaweed has received much attention in the pharmacological field owing to its various biomedical properties, including the prolongation of blood clotting time, as well as antitumor, anti-inflammation, and antioxidant effects. This study therefore aimed to examine the effects of a dietary polysaccharide-rich extract obtained from Eucheuma cottonii (EC) on a model of colitis. Colitis was induced in male BALB/c mice by the administration of 2.5% (w/v) dextran sulfate sodium (DSS) for 7 days. DSS-induced mice were treated with either one of three different doses of EC extracts (0.35, 0.70, and 1.75 g/kg body weight) or curcumin as a positive control (0.10 g/kg). Mice were sacrificed post-treatment and blood samples were collected. The disease activity index (DAI) and inflammatory cytokine levels (tumor necrosis factor (TNF)-alpha, interleukin (IL) 1beta, IL-6, IL-10) were measured. After treatment for 7 days, EC extract administration protected against weight loss and decreased the colon weight per length ratio. EC extract administration also decreased pro-inflammatory cytokine expression, increased IL-10 levels, and reduced colonic damage. Therefore, a dietary polysaccharide-rich extract from E. cottonii reduced DSS-induced bowel inflammation, thereby becoming a promising candidate for the treatment of colitis. PMID- 30289912 TI - Targeting obstetric providers in interventions for obesity and gestational weight gain: A systematic review. AB - BACKGROUND: Providers need to be comfortable addressing obesity and gestational weight gain so they may give appropriate care; however, health care providers lack guidelines for the most effective educational strategies to assist in providing optimal care. OBJECTIVE: To identify studies that involved the obstetric provider in interventions for either the perinatal management of obesity and/or gestational weight gain in a systematic review. SEARCH STRATEGY: A keyword search of databases was performed up to April 2017. SELECTION CRITERIA: Obstetric providers who participated in an intervention with the aim to change a provider's clinical practice, knowledge, and/or satisfaction with the intervention in relation to the perinatal management of obesity or gestational weight gain were included. Provider intervention could include training or education, changes in systems or organization of care, or resources to support practice. PROSPERO database #42016038921. DATA COLLECTION AND ANALYSIS: Bias was assessed according to the validated Mixed Methods Appraisal Tool. The following variables were synthesized: study location and setting, provider and patient characteristics, intervention features, outcomes and efficacy, and strengths and weakness. MAIN RESULTS: Of the 6,821 abstracts screened, seven studies (4 quantitative, 3 mixed-methods) with a total of 335 providers met the inclusion criteria; two of which focused on the management of obesity, three focused on gestational weight gain, and two focused on both topics. Interventions that incorporated motivational interviewing skills (n = 2), required additional training for the research study and addressed specific knowledge deficits such as nutrition and exercise (n = 3), and interfaced with the electronic medical record (n = 1) demonstrated the greatest impact on provider outcomes. Provider reported satisfaction scores were generally favorable, but none addressed provider-level efficacy in practice change. CONCLUSIONS: Given the limited number of studies, varying range of provider participation, and lack of provider-level efficacy, further evaluation of provider training and involvement in interventions for perinatal obesity or gestational weight gain is indicated to determine best practices for provider and patient outcomes. PMID- 30289914 TI - Routine analysis of ascitic fluid for evidence of infection in children with chronic liver disease: Is it mandatory? AB - Ascitic fluid infection is a major cause of morbidity and mortality in cirrhotic patients, requiring early diagnosis and therapy. We aimed to determine predictors of ascitic fluid infection in children with chronic liver disease. The study included 45 children with chronic liver disease and ascites who underwent 66 paracentesis procedures. Full history taking and clinical examination of all patients were obtained including fever, abdominal pain and tenderness and respiratory distress. Investigations included: complete blood count, C-reactive protein, full liver function tests, ascitic fluid biochemical analysis, cell count and culture. Our results showed that patients' ages ranged between 3 months to 12 years. Prevalence of ascitic fluid infection was 33.3%. Gram-positive bacteria were identified in six cases, and Gram-negative bacteria in five. Fever and abdominal pain were significantly more associated with infected ascites (p value = 0.004, 0.006). Patients with ascitic fluid infection had statistically significant elevated absolute neutrophilic count and C-reactive protein. Logistic regression analysis showed that fever, abdominal pain, elevated absolute neutrophilic count and positive C-reactive protein are independent predictors of ascitic fluid infection. Fever, elevated absolute neutrophilic count and positive C-reactive protein raise the probability of ascitic fluid infection by 3.88, 9.15 and 4.48 times respectively. The cut-off value for C-reactive protein for ascitic fluid infection was 7.2 with sensitivity 73% and specificity of 71%. In conclusion, prevalence of ascitic fluid infection in pediatric patients with chronic liver disease and ascites was 33.3%. Fever, abdominal pain, positive C reactive protein and elevated absolute neutrophilic count are strong predictors of ascitic fluid infection. Therefore an empirical course of first-line antibiotics should be immediately started with presence of any of these predictors after performing ascitic fluid tapping for culture and sensitivity. In absence of these infection parameters, routine ascitic fluid analysis could be spared. PMID- 30289915 TI - Lebbiea (Podostemaceae-Podostemoideae), a new, nearly extinct genus with foliose tepals, in Sierra Leone. AB - Lebbiea grandiflora (Podostemaceae), a rheophytic herb from the Sewa River rapids in Sierra Leone, is described as a new species. It is the first new African genus of Podostemaceae published for 30 years. First collected in May 2017, the species is assessed as Critically Endangered using the IUCN 2012 standard. It is on the edge of extinction with a small population at a single site threatened by deposition of gravel and sand from alluvial gold and diamond mining upstream, and a planned hydro-electric dam. The new genus is unique in Podostemaceae in a) its highly developed and robust style-stigma structure in which the bases of the two style-stigmas unite to form a bifurcate funneliform-cylindrical structure, with a reflexed, blade-like apex that extends half-way around the perimeter of the ovary fruit towards the base of the ovary-fruit, b) a specialised andropodium, with robust, self-supporting capacity, having differentiated thickened central, and angled, thinner marginal areas (in other Podostemaceae the andropodial structures are undifferentiated), c) the pillar-like haptera which completely elevate the crustose root above the substrate. Lebbiea is placed in Podostemoideae, necessitating amplification of the delimitation of that subfamily in which it is additionally unique in having the foliose tepals characteristic of the basal subfamilies Weddellinoideae and Tristichoideae. PMID- 30289916 TI - Analyzing bovine OCT4 and NANOG enhancer activity in pluripotent stem cells using fluorescent protein reporters. AB - Green fluorescent protein (GFP) reporters controlled by the regulatory region of OCT4 and NANOG-two master regulators for pluripotency are widely used in studies of pluripotent stem cell establishment and embryo development. Alongside the challenge in establishing bovine pluripotent stem cells, the application of bovine-specific gene reporters has rarely been explored. Using lentivirus-based GFP reporter, we investigated the upstream regulatory regions of bovine OCT4 and NANOG. These reporters show activity in both naive- and primed-state pluripotency when infected into mouse and human embryonic stem cells (ESCs), respectively. Consistent with what is found in humans and mice, the bovine OCT4-distal enhancer (bOCT4-DE) but not the proximal enhancer (bOCT4-PE) region is preferentially activated in naive-state pluripotency. Furthermore, the bOCT4-DE region is silenced upon conversion of naive-state ESCs into primed-state epiblast stem cells (EpiSCs). Co-infection of mouse fibroblasts with the reprograming factors for induced pluripotent stem cell (iPSC) induction leads to the generation of GFP positive colonies, demonstrating that these GFP reporters can serve as live indicators for induced pluripotent cell establishment. We further proved that the bovine OCT4 distal enhancer is active in bovine blastocysts. We established the lentiviral-based fluorescent reporters controlled by bovine OCT4 and NANOG enhancer sequences. These reporter constructs show activity in naive- and primed pluripotent states. These reporters may serve as versatile tools for bovine ESC/iPSC generation and identification, as well as for developmental studies of bovine embryos. PMID- 30289917 TI - The common rejection module in chronic rejection post lung transplantation. AB - RATIONALE: Recent studies suggest that similar injury mechanisms are in place across different solid organ transplants, resulting in the identification of a common rejection module (CRM), consisting of 11 genes that are overexpressed during acute and, to a lesser extent, chronic allograft rejection. OBJECTIVES: We wanted to evaluate the usefulness of the CRM module in identifying acute rejection (AR) and different phenotypes of chronic lung transplant rejection (CLAD), i.e., bronchiolitis obliterans syndrome (BOS) and restrictive allograft syndrome (RAS), using transbronchial brushings, broncho-alveolar lavage (BAL) samples, and explant tissue. METHODS: Gene expression measurements for the 11 CRM genes (CD6, TAP1, CXCL10, CXCL9, INPP5D, ISG20, LCK, NKG7, PSMB9, RUNX3, and BASP1) were performed via qRT-PCR in 14 transbronchial brushings (AR, n = 4; no AR, n = 10), 32 BAL samples (stable, n = 13; AR, n = 8; BOS, n = 9; RAS, n = 10), and 44 tissue specimens (unused donor lungs, n = 15; BOS, n = 13; RAS, n = 16). A geometric mean score was calculated to quantitate overall burden of immune injury and a new computational model was built for the most significant genes in lung transplant injury. RESULTS: Acute rejection showed a significant difference in almost every gene analysed, validating previous observations from microarray analysis. RAS tissue demonstrated a higher geometric mean score (6.35) compared to donor tissue (4.09, p = 0.018). Analysis of individual CRM genes showed an increased expression of ISG20, CXCL10 and CXCL9 in RAS. In BAL samples, no differences were detected in gene expression or geometric mean scores between the various groups (stable, 5.15; AR, 5.81; BOS, 5.62; RAS, 7.31). A newly modelled 2 gene tissue CRM score did not demonstrate any difference between BOS and RAS (p>0.05). However, the model was able to discriminate RAS from BOS tissue (AUC = 0.75, 95% CI = 0.55-0.94, p = 0.025). CONCLUSION: Transcriptional tissue analysis for CRM genes in CLAD can identify acute rejection and distinguish RAS from BOS. The immune activation in RAS seems similar to acute rejection after kidney/liver/heart transplantation. PMID- 30289918 TI - Simulation of the song motor pathway in birds: A single neuron initiates a chain of events that produces birdsong with realistic spectra properties. AB - Birdsong is a complex learned behavior regulated by Neuromuscular coordination of different muscle sets necessary for producing relevant sounds. We developed a heterogeneous and stochastically connected neural network representing the pathway from the high vocal center (HVC) to the robust nucleus of the arcopallium (RA) neurons that drive the muscles to generate sounds. We show that a single active neuron is sufficient to initiate a chain of spiking events that results to excite the entire network system. The network could synthesize realistic bird sounds spectra, with spontaneous generation of intermittent sound bursts typical of birdsong (song syllables). This study confirms experiments on animals and on humans, where results have shown that single neurons are responsible for the activation of complex behavior or are associated with high-level perception events. PMID- 30289919 TI - Long-term trends in incidence and risk factors for ischaemic stroke subtypes: Prospective population study of the South London Stroke Register. AB - BACKGROUND: As the average life expectancy increases, more people are predicted to have strokes. Recent studies have shown an increasing incidence in certain types of cerebral infarction. We aimed to estimate time trends in incidence, prior risk factors, and use of preventive treatments for ischaemic stroke (IS) aetiological subtypes and to ascertain any demographic disparities. METHODS AND FINDINGS: Population-based data from the South London Stroke Register (SLSR) between 2000 and 2015 were studied. IS was classified, based on the underlying mechanism, into large-artery atherosclerosis (LAA), cardio-embolism (CE), small vessel occlusion (SVO), other determined aetiologies (OTH), and undetermined aetiologies (UND). After calculation of age-, sex-, and ethnicity-specific incidence rates by subtype for the 16-year period, we analysed trends using Cochran-Armitage tests, Poisson regression models, and locally estimated scatterplot smoothers (loess). A total of 3,088 patients with first IS were registered. Between 2000-2003 and 2012-2015, the age-adjusted incidence of IS decreased by 43% from 137.3 to 78.4/100,000/year (incidence rate ratio [IRR] 0.57, 95% CI 0.5-0.64). Significant declines were observed in all subtypes, particularly in SVO (37.4-18; p < 0.0001) and less in CE (39.3-25; p < 0.0001). Reductions were recorded in males and females, younger (<55 years old) and older (>=55 years old) individuals, and white and black ethnic groups, though not significantly in the latter (144.6-116.2; p = 0.31 for IS). A 4-fold increase in prior-to-stroke use of statins was found (adjusted odds ratio [OR] 4.39, 95% CI 3.29-5.86), and despite the increasing prevalence of hypertension (OR 1.54, 95% CI 1.21-1.96) and atrial fibrillation (OR 1.7, 95% CI 1.22-2.36), preventive use of antihypertensive and antiplatelet drugs was declining. A smaller number of participants in certain subgroup-specific analyses (e.g., black ethnicity and LAA subtype) could have limited the power to identify significant trends. CONCLUSIONS: The incidence of ISs has been declining since 2000 in all age groups but to a lesser extent in the black population. The reported changes in medication use are unlikely to fully explain the reduction in stroke incidence; however, innovative prevention strategies and better management of risk factors may contribute further reduction. PMID- 30289920 TI - Position effect, cryptic complexity, and direct gene disruption as disease mechanisms in de novo apparently balanced translocation cases. AB - The majority of apparently balanced translocation (ABT) carriers are phenotypically normal. However, several mechanisms were proposed to underlie phenotypes in affected ABT cases. In the current study, whole-genome mate-pair sequencing (WG-MPS) followed by Sanger sequencing was applied to further characterize de novo ABTs in three affected individuals. WG-MPS precisely mapped all ABT breakpoints and revealed three possible underlying molecular mechanisms. Firstly, in a t(X;1) carrier with hearing loss, a highly skewed X-inactivation pattern was observed and the der(X) breakpoint mapped ~87kb upstream an X-linked deafness gene namely POU3F4, thus suggesting an underlying long-range position effect mechanism. Secondly, cryptic complexity and a chromothripsis rearrangement was identified in a t(6;7;8;12) carrier with intellectual disability. Two translocations and a heterozygous deletion disrupted SOX5; a dominant nervous system development gene previously reported in similar patients. Finally, a direct gene disruption mechanism was proposed in a t(4;9) carrier with dysmorphic facial features and speech delay. In this case, the der(9) breakpoint directly disrupted NFIB, a gene involved in lung maturation and development of the pons with important functions in main speech processes. To conclude, in contrast to familial ABT cases with identical rearrangements and discordant phenotypes, where translocations are considered coincidental, translocations seem to be associated with phenotype presentation in affected de novo ABT cases. In addition, this study highlights the importance of investigating both coding and non-coding regions to decipher the underlying pathogenic mechanisms in these patients, and supports the potential introduction of low coverage WG-MPS in the clinical investigation of de novo ABTs. PMID- 30289921 TI - A biomechanical assessment of hydraulic ankle-foot devices with and without micro processor control during slope ambulation in trans-femoral amputees. AB - Slope ambulation is a challenge for trans-femoral amputees due to a relative lack of knee function. The assessment of prosthetic ankles on slopes is required for supporting the design, optimisation, and selection of prostheses. This study assessed two hydraulic ankle-foot devices (one of the hydraulic ankles is controlled by a micro-processor that allows real-time adjustment in ankle resistance and range of motion) used by trans-femoral amputees in ascending and descending a 5-degree slope walking, against a rigid ankle-foot device. Five experienced and active unilateral trans-femoral amputees performed ascending and descending slope tests with their usual prosthetic knee and socket fitted with a rigid ankle-foot, a hydraulic ankle-foot without a micro-processor, and a hydraulic ankle-foot with a micro-processor optimised for ascending and descending slopes. Peak values in hip, knee and ankle joint angles and moments were collected and the normalcy Trend Symmetry Index of the prosthetic ankle moments (as an indication of bio-mimicry) were calculated and assessment. Particular benefits of the hydraulic ankle-foot devices were better bio-mimicry of ankle resistance moment, greater range of motion, and improved passive prosthetic knee stability according to the greater mid-stance external knee extensor moment (especially in descending slope) compared to the rigid design. The micro-processor controlled device demonstrated optimised ankle angle and moment patterns for ascending and descending slope respectively, and was found to potentially further improve the ankle moment bio-minicry and prosthetic knee stability compared to the hydraulic device without a micro-processor. However the difference between the micro-processor controlled device and the one without a micro-processor does not reach a statistically significant level. PMID- 30289922 TI - Changes in the West African forest-savanna mosaic, insights from central Togo. AB - The West African forest-savanna mosaic, an important habitat for biodiversity and humans, is severely degraded, fragmented and modified by human activities. However, few studies have quantified the land cover changes observed over time and/or analysed the drivers of change. This study focused on Fazao-Malfakassa National Park, the largest in Togo, uses a combination of remote sensing, ground surveys and questionnaires to: (i) quantify vegetation changes, (ii) determine the drivers of change, (iii) compare results with findings elsewhere in the region and (iv) suggest management interventions. The images used were Landsat 5 TM, Landsat 7 ETM and Sentinel-2. Different vegetation indices were computed including: number of fragments, index of dominance, mean area of a vegetation type and mean annual expansion rate. In total, 300 people (including park staff and local populations) were interviewed using a semi-structured questionnaire. Results indicate that between 1987 and 2015 closed-canopy forest and tree-savanna became severely degraded and fragmented, following trends in other parts of the West African forest-savanna mosaic. The main drivers of change were agricultural expansion, bush fires and timber extraction. Observed changes and drivers altered with time: e.g. agricultural expansion was greatest during 1987-2001 (linked with political instability) while illegal timber extraction augmented during 2001-2015 (following increased timber value). Park staff and local populations' perceptions on drivers of change did not differ. Our study highlights that action is urgently needed if we are to preserve this important habitat, the biodiversity it hosts and the services it provides to humans. We suggest several management interventions, learning from successful interventions elsewhere in the region.

AB - Ratings are present in many areas of assessment including peer review of research proposals and journal articles, teacher observations, university admissions and selection of new hires. One feature present in any rating process with multiple raters is that different raters often assign different scores to the same assessee, with the potential for bias and inconsistencies related to rater or assessee covariates. This paper analyzes disparities in ratings of internal and external applicants to teaching positions using applicant data from Spokane Public Schools. We first test for biases in rating while accounting for measures of teacher applicant qualifications and quality. Then, we develop model-based inter-rater reliability (IRR) estimates that allow us to account for various sources of measurement error, the hierarchical structure of the data, and to test whether covariates, such as applicant status, moderate IRR. We find that applicants external to the district receive lower ratings for job applications compared to internal applicants. This gap in ratings remains significant even after including measures of qualifications and quality such as experience, state licensure scores, or estimated teacher value added. With model-based IRR, we further show that consistency between raters is significantly lower when rating external applicants. We conclude the paper by discussing policy implications and possible applications of our model-based IRR estimate for hiring and selection practices in and out of the teacher labor market.

In this article, in order to obtain the S-parameters of the special twisted pair cable with rectangular connectors, a de-embedding method of the transmission matrix is proposed to deal with the two adapters ends of the cable. According to the frequency-dependent RLGC(f) model, the cable characteristics are extracted in the frequency range of 10 MHz to 200 MHz through conventional and modified methods respectively. The frequency-domain analysis shows that the inherent capacity of modified method can decrease the errors especially due to the discontinuities of hyperbolic functions. This research supplies an advantageous modelling approach for the cable to improve its robustness against disturbances in the S-parameters measurement that cannot be decreased with the calibration procedure. PMID- 30289925 TI - Corneal transplantation for Fuchs' endothelial dystrophy: A comparison of three surgical techniques concerning 10 year graft survival and visual function. AB - OBJECTIVE: Comparison of conventional Penetrating Keratoplasty (PKP), posterior mushroom PKP and Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK) regarding overall graft survival of primary corneal transplants for Fuchs' endothelial dystrophy (FED), best spectacle-corrected visual acuity (BSCVA) and astigmatism. METHODS: Single centre study using prospectively collected data from the national database for follow-up of corneal transplants. Main outcome parameters: 10 years graft survival, astigmatism at 24 months, pre- and post operative BSCVA. RESULTS: In total, 721 cases were included: PKP, n = 171; posterior mushroom PKP, n = 91; and DSAEK, n = 459. There was no significant difference in graft survival between PKP, posterior mushroom PKP and the DSAEK technique (log-rank test, P = 0.12). The overall post-operative BSCVA improvement in all treatment groups was significant (paired t-test, P<0.001). Pre-operative BSCVA was better for the DSAEK group (0.68 +/- 0.41 logMAR) as compared to the PKP (0.89 +/- 0.53) and posterior mushroom PKP group (0.90 +/- 0.58); ANOVA, P<0.001. After 24 months, BSCVA was significantly better for the DSAEK group (0.25 +/- 0.26 logMAR) compared to the PKP (0.35 +/- 0.29) and posterior mushroom PKP group (0.41 +/- 0.42); ANOVA, P<0.001. A significant difference in astigmatism was found (median test, P<0.001) between the DSAEK (1.7 +/- 1.1 D), PKP (4.6 +/- 2.7 D) and posterior mushroom PKP group (4.5 +/- 3.3 D). The significantly lower DSAEK-induced astigmatism was confirmed by vector analysis. CONCLUSION: There was no difference in graft survival and BSCVA improvement between conventional PKP, inverted mushroom PKP and DSAEK in this study. The significantly lower changes in astigmatism, wound stability and faster visual rehabilitation with DSAEK surgery are favourable aspects of this technique. The benefits of posterior lamellar keratoplasty warrant earlier intervention, which may contribute to preserve better vision for a prolonged period of remaining lifetime. PMID- 30289926 TI - Conceptual model for the health technology assessment of current and novel interventions in rheumatoid arthritis. AB - The objective of this study was to evaluate current approaches to economic modeling in rheumatoid arthritis (RA) and propose a new conceptual model for evaluation of the cost-effectiveness of RA interventions. We followed recommendations from the International Society of Pharmacoeconomics and Outcomes Research-Society of Medical Decision Making (ISPOR-SMDM) Modeling Good Research Practices Task Force-2. The process involved scoping the decision problem by a working group and drafting a preliminary cost-effectiveness model framework. A systematic literature review (SLR) of existing decision-analytic models was performed and analysis of an RA registry was conducted to inform the structure of the draft conceptual model. Finally, an expert panel was convened to seek input on the draft conceptual model. The proposed conceptual model consists of three separate modules: 1) patient characteristic module, 2) treatment module, and 3) outcome module. Consistent with the scope, the conceptual model proposed six changes to current economic models in RA. These changes proposed are to: 1) use composite measures of disease activity to evaluate treatment response as well as disease progression (at least two measures should be considered, one as the base case and one as a sensitivity analysis); 2) conduct utility mapping based on disease activity measures; 3) incorporate subgroups based on guideline recommended prognostic factors; 4) integrate realistic treatment patterns based on clinical practice/registry datasets; 5) assimilate outcomes that are not joint related (extra-articular outcomes); and 6) assess mortality based on disease activity. We proposed a conceptual model that incorporates the current understanding of clinical and real-world evidence in RA, as well as of existing modeling assumptions. The proposed model framework was reviewed with experts and could serve as a foundation for developing future cost-effectiveness models in RA. PMID- 30289927 TI - Clinical significance of the Kidney Donor Profile Index in deceased donors for prediction of post-transplant clinical outcomes: A multicenter cohort study. AB - BACKGROUND: We investigated whether the Kidney Donor Profile Index (KDPI) system is useful in predicting clinical outcomes in deceased donor kidney transplantation (DDKT). METHODS: Four hundred sixty-nine kidney transplant recipients (KTRs) receiving kidneys from 359 deceased donors were included in this study, which involved three transplant centers. KTRs were divided into high and low KDPI KTR groups based on the median KDPI score of 67%. We compared clinical outcomes between the high KDPI and low KDPI groups. RESULTS: There were no significant differences in the incidence of delayed graft function and acute rejection between high and low KDPI KTR groups. In comparison with histologic findings in allograft tissues obtained within three months from KT, the proportion of glomerulosclerosis was significantly higher in the high KDPI KTR group than in the low KDPI KTR group. With Kaplan-Meier analysis, the graft survival rate was significantly lower in the high KDPI KTR group than in the low KDPI KTR group (Log rank, P = 0.017), and multivariate analysis also demonstrated that a high KDPI score was a significant risk factor for death censored allograft failure (HR 2.62, 95% CI, 1.29-5.33, P = 0.008). CONCLUSION: The KDPI scoring system is useful in predicting allograft outcomes in a Korean DDKT cohort. PMID- 30289928 TI - Parenting behaviors that shape child compliance: A multilevel meta-analysis. AB - BACKGROUND: What are the parenting behaviors that shape child compliance? Most research on parent-child interactions relies on correlational research or evaluations of "package deal" interventions that manipulate many aspects of parenting at the same time. Neither approach allows for identifying the specific parenting behaviors that shape child compliance. To overcome this, we systematically reviewed and meta-analyzed available evidence on the effects of experimentally manipulated, discrete parenting behaviors-a niche in parent-child interaction research that contributes unique information on the specific parenting behaviors that shape child behavior. METHODS: We identified studies by systematically searching databases and through contacting experts. Nineteen studies (75 effect sizes) on four discrete parenting behaviors were included: praise, verbal reprimands, time-out, and ignore. In multilevel models, we tested for each parenting behavior whether it increased child compliance, including both observed and parent-reported measures of child compliance. RESULTS: Providing "time-out" for noncompliance robustly increased both observed and parent-reported child compliance (ds = 0.84-1.72; 95% CI 0.30 to 2.54). The same holds for briefly ignoring the child after non-compliance (ds = 0.36-1.77; 95% CI 0.04 to 2.90). When observed and parent-reported outcomes were combined, but not when they were examined separately, verbal reprimands also increased child compliance (d = 0.72; 95% CI 0.26 to 1.19). Praise did not increase child compliance (ds = 0.27-1.19; 95% CI -2.04 to 1.59). CONCLUSION: Our findings suggest that of the discrete parenting behaviors that are experimentally studied in multiple trials, especially time-out and ignore, and to some extent verbal reprimands, shape child compliance. PMID- 30289929 TI - Aminoglycoside-inducible expression of the mexAB-oprM multidrug efflux operon in Pseudomonas aeruginosa: Involvement of the envelope stress-responsive AmgRS two component system. AB - Exposure of P. aeruginosa to the aminoglycoside (AG) paromomycin (PAR) induced expression of the PA3720-armR locus and the mexAB-oprM multidrug efflux operon that AmgR controls, although PAR induction of mexAB-oprM was independent of armR. Multiple AGs promoted mexAB-oprM expression and this was lost in the absence of the amgRS locus encoding an aminoglycoside-activated envelope stress-responsive 2 component system (TCS). Purified AmgR bound to the mexAB-oprM promoter region consistent with this response regulator directly regulating expression of the efflux operon. The thiol-active reagent, diamide, which, like AGs, promotes protein aggregation and cytoplasmic membrane damage also promoted AmgRS-dependent mexAB-oprM expression, a clear indication that the MexAB-OprM efflux system is recruited in response to membrane perturbation and/or circumstances that lead to this. Despite the AG and diamide induction of mexAB-oprM, however, MexAB-OprM does not appear to contribute to resistance to these agents. PMID- 30289930 TI - Design and validation of an open-source modular Microplate Photoirradiation System for high-throughput photobiology experiments. AB - Research in photobiology is currently limited by a lack of devices capable of delivering precise and tunable irradiation to cells in a high-throughput format. This limits researchers to using expensive commercially available or custom-built light sources which make it difficult to replicate, standardize, optimize, and scale experiments. Here we present an open-source Microplate Photoirradiation System (MPS) developed to enable high-throughput light experiments in standard 96 and 24-well microplates for a variety of applications in photobiology research. This open-source system features 96 independently controlled LEDs (4 LEDs per well in 24-well), Wi-Fi connected control and programmable graphical user interface (GUI) for control and programming, automated calibration GUI, and modular control and LED boards for maximum flexibility. A web-based GUI generates light program files containing irradiation parameters for groups of LEDs. These parameters are then uploaded wirelessly, stored and used on the MPS to run photoirradiation experiments inside any incubator. A rapid and semi-quantitative porphyrin metabolism assay was also developed to validate the system in wild-type fibroblasts. Protoporphyrin IX (PpIX) fluorescence accumulation was induced by incubation with 5-aminolevulinic acid (ALA), a photosensitization method leveraged clinically to destroy malignant cell types in a process termed photodynamic therapy (PDT), and cells were irradiated with 405nm light with varying irradiance, duration and pulsation parameters. Immediately after light treatment with the MPS, subsequent photobleaching was measured in live, adherent cells in both 96-well and a 24-well microplates using a microplate reader. Results demonstrate the utility and reliability of the Microplate Photoirradiation System to irradiate cells with precise irradiance and timing parameters in order to measure PpIx photobleaching kinetics in live adherent cells and perform comparable experiments with both 24 and 96 well microplate formats. The high-throughput capability of the MPS enabled measurement of enough irradiance conditions in a single microplate to fit PpIX fluorescence to a bioexponential decay model of photobleaching, as well as reveal a dependency of photobleaching on duty-cycle-but not frequency-in a pulsed irradiance regimen. PMID- 30289931 TI - Compound C inhibits nonsense-mediated RNA decay independently of AMPK. AB - The nonsense mediated RNA decay (NMD) pathway safeguards the integrity of the transcriptome by targeting mRNAs with premature translation termination codons (PTCs) for degradation. It also regulates gene expression by degrading a large number of non-mutant RNAs (including mRNAs and noncoding RNAs) that bear NMD inducing features. Consequently, NMD has been shown to influence development, cellular response to stress, and clinical outcome of many genetic diseases. Small molecules that can modulate NMD activity provide critical tools for understanding the mechanism and physiological functions of NMD, and they also offer potential means for treating certain genetic diseases and cancer. Therefore, there is an intense interest in identifying small-molecule NMD inhibitors or enhancers. It was previously reported that both inhibition of NMD and treatment with the AMPK selective inhibitor Compound C (CC) induce autophagy in human cells, raising the possibility that CC may be capable of inhibiting NMD. Here we show that CC indeed has a NMD-inhibitory activity. Inhibition of NMD by CC is, however, independent of AMPK activity. As a competitive ATP analog, CC does not affect the kinase activity of SMG1, an essential NMD factor and the only known kinase in the NMD pathway. However, CC treatment down-regulates the protein levels of several NMD factors. The induction of autophagy by CC treatment is independent of ATF4, a NMD target that has been shown to promote autophagy in response to NMD inhibition. Our results reveal a new activity of CC as a NMD inhibitor, which has implications for its use in basic research and drug development. PMID- 30289932 TI - Hypoxia/reperfusion predisposes to atherosclerosis. AB - Surgical interventions on blood vessels bear a risk for intimal hyperplasia and atherosclerosis as a consequence of injury. A specific feature of intimal hyperplasia is the loss of vascular smooth muscle cell (VSMC) differentiation gene expression. We hypothesized that immediate responses following injury induce vascular remodeling. To differentiate injury due to trauma, reperfusion and pressure changes we analyzed vascular responses to carotid artery bypass grafting in mice compared to transient ligation. As a control, the carotid artery was surgically laid open only. In both, bypass or ligation models, the inflammatory responses were transient, peaking after 6h, whereas the loss of VSMC differentiation gene expression persisted. Extended time kinetics showed that transient carotid artery ligation was sufficient to induce a persistent VSMC phenotype change throughout 28 days. Transient arterial ligation in ApoE knockout mice resulted in atherosclerosis in the transiently ligated vascular segment but not on the not-ligated contralateral side. The VSMC phenotype change could not be prevented by anti-TNF antibodies, Sorafenib, Cytosporone B or N-acetylcysteine treatment. Surgical interventions involving hypoxia/reperfusion are sufficient to induce VSMC phenotype changes and vascular remodeling. In situations of a perturbed lipid metabolism this bears the risk to precipitate atherosclerosis. PMID- 30289933 TI - Risk of malignant skin neoplasms in a cohort of workers occupationally exposed to ionizing radiation at low dose rates. AB - Recently an increasing trend in skin cancer rates has been observed in various populations including those exposed to different radiation types. Risk and dose response following prolonged radiation exposure remain unclear. The present study was aimed to assess skin melanoma (SM) and non-melanoma skin cancer (NMSC) incidence risks in a cohort of workers occupationally exposed to ionizing radiation at low dose rates over prolonged periods. The study cohort included workers of a Russian nuclear production facility, Mayak Production Association (PA), who were first employed in 1948-1982 and followed up till the end of 2013 (the total of 22,377 individuals with 25% of females). Using AMFIT module of EPICURE software, relative risk and excess relative risk per unit dose (RR and ERR/Sv) were calculated. 60 SM and 294 NMSC cases were registered in members of the study cohort. SM and NMSC incidence was dependent on sex, attained age, age at first employment at the enterprise, type of facility, education level and was not dependent on calendar period of first employment, calendar period of diagnosis, duration of employment, smoking and alcohol consumption statuses. The risk of NMSC incidence was found to be significantly increased in workers occupationally exposed to ionizing radiation at cumulative doses above 2.0 Sv (RR = 2.52; 95% CI: 1.60, 3.97) compared to a reference dose category (0-0.05 Sv). NMSC incidence was found to be significantly associated with cumulative external gamma-dose with ERR/Sv of 0.49 (95% CI: 0.22, 0.90) without an adjustment for neutron dose and 0.51 (95% CI: 0.22, 0.93) while adjusted for neutron dose. Results of the analysis did not reveal a significant association of SM incidence with cumulative dose from external gamma-rays with ERR/Sv of 0.22 (95% CI: -0.29, 1.46) not including a neutron dose adjustment and of 0.15 (95% CI: -0.41, 1.31) while adjusted for dose from neutron exposure. PMID- 30289934 TI - Quantitative spectral assessment of intracardiac electrogram characteristics associated with post infarct fibrosis and ventricular tachycardia. AB - BACKGROUND: Post-myocardial infarction (MI) remodeling contributes to increased electrophysiological and structural heterogeneity and arrhythmogenesis. Utilising the post-infarct ovine model our aim was to determine unipolar electrogram frequency characteristics consequent to this remodeling and the development of Ventricular Tachycardia (VT). METHODS AND RESULTS: Mapping studies were performed on 14 sheep at >1 month post-MI induction. Sheep were divided into VT inducible (n = 7) and non-inducible (n = 7) groups. Multielectrode needles (n = 20) were deployed within and surrounding ventricular scar for electrophysiological assessment of electrogram amplitude and width. Spectral analysis of electrograms was undertaken using wavelet and fast fourier transformations (WFFT) to calculate root mean square (RMS) power intervals spanning 0-300Hz in 20Hz intervals. Quantitative assessment between electrophysiological and histological parameters including collagen density, and structural organization of the myocardium was performed. Increasing myocardial scar density resulted in attenuation of electrogram amplitude and RMS values. (all p<0.01). Between groups there were no differences in electrogram amplitude (p = 0.37), however WFFT analysis revealed significantly higher RMS values in the VT group (p<0.05) in association with high frequency fractional components of the electrogram. As scar density increased, greater between-group differences in RMS were observed spanning this high frequency (200-280Hz) spectrum and which were proportionally dependent on the degree of structural disorganisation of the myocardium (p<0.001) and number of extrastimuli required to induce VT (p<0.05). CONCLUSION: High frequency unipolar electrogram spectral characteristics were quantitatively co-influenced by the presence of fibrosis and degree of myocardial structural dissorganisation and were associated with the propensity for development of VT. PMID- 30289935 TI - Health system measurement: Harnessing machine learning to advance global health. AB - BACKGROUND: Further improvements in population health in low- and middle-income countries demand high-quality care to address an increasingly complex burden of disease. Health facility surveys provide an important but costly source of information on readiness to provide care. To improve the efficiency of health system measurement, we applied unsupervised machine learning methods to assess the performance of the service readiness index (SRI) defined by the World Health Organization and compared it to empirically derived indices. METHODS: We drew data from nationally representative Service Provision Assessment surveys conducted in 10 countries between 2007 and 2015. We extracted 649 items in domains such as infrastructure, medication, and management to calculate an index using all available information and classified facilities into quintiles. We compared three approaches against the full item set: the SRI, a new index based on sequential backward selection, and an enriched SRI that added empirically selected items to the SRI. We evaluated index performance with a cross-validated kappa statistic comparing classification using the candidate index against the 649-item index. RESULTS: 9238 facilities were assessed. The 49-item SRI performed poorly against the index using all 649 items, with a kappa value of 0.35. New empirically derived indices with 50 and 100 items captured much more information, with cross-validated kappa statistics of 0.71 and 0.80, respectively. Items varied across the indices and in sensitivity analyses. A 100-item enriched SRI reliably captured the information from the full index: 83% of the facilities were classified into correct quintiles of service readiness based on the full index. CONCLUSION: A facility readiness measure developed by global health experts performed poorly in capturing the totality of readiness information collected during facility surveys. Using a machine learning approach with sequential selection and cross-validation to identify the most informative items dramatically improved performance. Such approaches can make assessment of health facility readiness more efficient. Further improvements in measurement will require identification of external criteria-such as patient outcomes-to guide and validate measure development. PMID- 30289936 TI - Assessment of ecosystem services of an urbanized tropical estuary with a focus on habitats and scenarios. AB - Tropical estuaries are one of the most valuable ecosystems on the planet because of the number of ecosystem services they provide. The increasing anthropogenic pressure to which these estuaries are subject has caused a reduction in their natural capital stock. Therefore, the application of a pragmatic and rational ecosystem-based management approach to sustainably manage the multiple ecosystem services provided by this ecosystem is necessary. The aim of our study is to present an approach that combines prospective scenarios with habitat-based perspective to assess the supply capacity of ecosystem services, plus determine the impact of protected areas in an urbanized tropical estuary. The current situation and two scenarios were generated to evaluate the capacity of habitats to supply ecosystem services. This type of assessment will allow the decision makers to visualize the effect of their choices or the occurrence of events which might produce significant changes in the estuary. Thus, over time, measures can be taken to sustain the supply of ecosystem services. We determined that the establishment of protected areas have a positive impact; however, the effect is not the same for all of them. Consequently, indicating that actions such as community participation, research, education, management planning and infrastructure development must accompany the development of a protected area.

AB - Because using social media has become a major part of people's daily lives, many of their personal characteristics are often implicitly or explicitly reflected in the content they share. We present a study of two personal characteristics-age and gender-related to user engagement on Instagram that can be determined through the characterization of images and tags. We demonstrate the strong influence of age and gender on Instagram use in terms of topical and content differences. We then build age and gender classification models that yield F1 scores of up to 88% and 74% in the detection of age and gender, respectively, and that better characterize users by images than by tags. We further demonstrate the robustness of our models using a new set of test data, with which the models exhibit greater overall performance than human raters. Our study highlights that future research should look to exploit images to a greater degree because they complement text and there are many unexamined images with no embedded text available.

AB - The paper investigates the effect of preferential gathering sites on urban insurgency in an agent-based model (ABM). The ABM model was proposed in earlier work and has been validated using FBI data. There is a nonlinear tradeoff between the local density of citizens due to the number of preferential gathering sites and the ability of law enforcement officers (LEOs) to adequately patrol that leads to a non-monotonic behavior in the number of large scale outburst of insurgency with respect to the number of gathering sites. The inclusion of a moderate number of sites decreases the number of large-scale outbursts. Having no gathering sites or a large number of gathering sites has a dilutive effect on the number of large-scale outbursts. Thus, this non-monotonicity indicates that a small number of organized units produces a larger insurgency effect than a larger number of distributed units. It is also shown, using Koopman mode analysis, that the spatial morphology of agents due to the gathering sites gives rise to temporal organization of the model dynamics; there is a prominent quasi-periodic component in the number of active and intimidated citizens and in the spatial distribution of the LEOs.

AB - Phellinus igniarius, which is called Sanghuang in Chinese, is a fungal herb widely used in Traditional Chinese Medicine to treat stomachache, inflammation and tumors. Recent studies have demonstrated the antitumor, anti-diabetic, anti inflammatory and immunity-modulating activities of P. igniarius. In the present study, we investigated that ameliorating effect of the aqueous extract of P. igniarius fruiting body (SH) on dextran sodium sulfate (DSS)-induced colitis in C57BL/6 mice. Treatment with SH (250 and 400 mg/kg) for 8 weeks effectively alleviated the pathological indicators of colitis such as bodyweight reduction, disease activity index score, shortening of colon length and abnormal colon histology. The plasma levels of lipopolysaccharide (LPS) and inflammatory factors such as interleukin-6 (IL-6), IL-1beta and tumor necrosis factor (TNF)-alpha were all significantly reduced. Supplementation of SH (10 mg/L) also inhibited LPS elicited IL-1beta production by RAW264.7 macrophages. Real-time PCR and western blot showed that treatment with SH significantly inhibited the phosphorylation of nuclear factor kappa B inhibitor alpha (IkappaBalpha) and decreased the expression of IL-6/IL-1beta-maturation genes such as apoptosis-associated speck like protein (ASC3) and caspase-1 in the colon of DSS-induced colitis mice. These results suggest that SH is adequate for the treatment of colitis. Inhibiting the expression and release of inflammatory factors may participate in the colitis ameliorating effect of SH.

AB - INTRODUCTION: Relation between atrial fibrillation (AF) and cancer is known but not very well understood. The purpose of this prospective study was to find out whether subjects with cancer were at greater risk of AF than subjects without cancer. MATERIALS AND METHODS: The study was based on the OPERA (Oulu Project Elucidating Risk of Atherosclerosis) material and had 1045 subjects and the mean follow-up time of 16.3 years. During the follow-up AF and cancer diagnosis were made (atrial flutter included) if these events were listed in the National Death Registry and/or hospital discharge registry. RESULTS: In this study 130 subjects (12%) had cancer and 19% of these had AF, whereas only 9% of those without cancer experienced AF during the follow-up (p<0.001). Subjects in the cancer group had greater probability of developing atrial fibrillation during the follow-up time in comparison to the subjects without cancer (Hazard ratio (HR) 2.47 (95%CI) 1.57 3.88) in multivariate model including relevant confounding factors. CONCLUSION: The main finding of this OPERA study was that cancer is an independent risk factor of atrial fibrillation. Still it remains unclear whether this association is causative or whether cancer and atrial fibrillation just share the same pathophysiologic mechanisms. PMID- 30289946 TI - Effects of climatically-modulated changes in solar radiation and wind speed on spring phytoplankton community dynamics in Lake Taihu, China. AB - Many studies have focused on the interactive effects of temperature increases due to global warming and nutrient enrichment on phytoplankton communities. Recently, non-temperature effects of climate change (e.g., decreases in wind speed and increases in solar radiation) on large lakes have received increasing attention. To evaluate the relative contributions of both temperature and non-temperature effects on phytoplankton communities in a large eutrophic subtropical shallow lake, we analyzed long-term monitoring data from Lake Taihu, China from 1997 to 2016. Results showed that Lake Taihu's spring phytoplankton biovolume and composition changed dramatically over this time frame, with a change in dominant species. Stepwise multiple linear regression models indicated that spring phytoplankton biovolume was strongly influenced by total phosphorus (TP), light condition, wind speed and total nitrogen (TN) (radj2 = 0.8, p < 0.01). Partial redundancy analysis (pRDA) showed that light condition accounted for the greatest variation of phytoplankton community composition, followed by TP and wind speed, as well as the interactions between TP and wind speed. Our study points to the additional importance of non-temperature effects of climate change on phytoplankton community dynamics in Lake Taihu. PMID- 30289945 TI - Impact of current smoking on 2-year clinical outcomes between durable-polymer coated stents and biodegradable-polymer-coated stents in acute myocardial infarction after successful percutaneous coronary intervention: Data from the KAMIR. AB - OBJECTIVE: Data concerning the effect of current smoking on solely new-generation drug-eluting stents (DES) are limited. We investigated the impact of current smoking on 2-year clinical outcomes between durable-polymer (DP)-coated DES (zotarolimus-eluting [ZES] and everolimus eluting [EES]) and biodegradable polymer (BP)-coated biolimus-eluting stent (BES) in acute myocardial infarction (AMI) patients after successful percutaneous coronary intervention (PCI). METHODS: Finally, a total of 8357 AMI patients with current smoking underwent successful PCI with new-generation DES (ZES, EES, and BES) were enrolled and divided into three groups as ZES (n = 3199), EES (n = 3987), and BES group (n = 1171). The primary endpoint was the occurrence of major adverse cardiac events (MACE) defined as all-cause death (cardiac death [CD] or non-cardiac death), recurrent AMI (re-MI), any revascularization (target lesion revascularization [TLR], target vessel revascularization [TVR], and non-TVR). The secondary endpoint was the incidence of definite or probable stent thrombosis (ST). RESULTS: The 2-year adjusted hazard ratio (HR) of MACE for ZES vs. EES (1.055; 95% confidence interval [CI], 0.843-1.321; p = 0.638), ZES vs. BES (HR, 0.885; 95% CI, 0.626-1.251; p = 0.488), EES vs. BES (HR, 0.889; 95% CI, 0.633-1.250; p = 0.499), and ZES/EES vs. BES (HR, 0.891; 95% CI, 0.648-1.126; p = 0.480) were similar. The occurrence of ST after adjustment were also comparable. In addition, the 2-year adjusted HR for all-cause death, CD, re-MI, TLR, TVR, and non-TVR were not different. CONCLUSIONS: In this study, DP-DES and BP-DES showed comparable safety and efficacy during 2-year follow-up periods. Therefore, DP-DES or BP-DES are equally acceptable in AMI patients with current smoking undergoing PCI.

AB - Burn patients have a high risk of sepsis-related mortality even after surviving the initial injury. Immunosuppression increases the risk of sepsis after burn injury, as does the disruption of the intestinal epithelial barrier, which allows the translocation of bacteria and bacterial products into the circulation. The integrity of the intestinal epithelial barrier is largely maintained by the intestinal microbiota. Burn injury has been reported to result in significant changes in the intestinal microbiome composition. In this mouse study, we confirm these taxonomic differences in a full-thickness scald injury model using CF-1 mice. For the first time, we also address alterations in functional gene expression of the intestinal microbiota after burn injury to assess the microbiome's physiological capabilities for overgrowth and pathogenic invasion: 38 pathways were differentially abundant between the sham and burn injury mice, including bacterial invasion of epithelial cells and gap- and adherens junction pathways.

AB - BACKGROUND: We previously reported association of SCARB1 SNP rs10846744 with common carotid IMT (cIMT) and cardiovascular disease (CVD) events. Since rs10846744 has been reported in association with Lp-PLA2 mass and activity, we hypothesized that inflammatory pathways might mediate the association of rs10846744 with atherosclerosis. METHODS: We first examined association of rs10846744 in CVD in multiple large-scale consortium-based genome-wide association studies. We further examined 27 parameters of interest, including Lp PLA2 mass and activity, inflammatory markers, and plasma phospholipid fatty acids, and fatty acid ratios in participants from the Multi-Ethnic Study of Atherosclerosis (MESA), as potential mediators in the pathway linking rs10846744 with cIMT and incident CVD. Finally, we examined the association of rs10846744 with Lp-PLA2 activity, cardiovascular outcomes, and interaction with the Lp-PLA2 inhibitor, darapladib, in the Stabilization of Atherosclerotic Plaque by Initiation of Darapladib Therapy (STABILITY) and Stabilization of Plaque using Darapladib-Thrombolysis in Myocardial Infarction 52 (SOLID-TIMI 52) studies. RESULTS: SCARB1 rs10846744 was associated with coronary artery disease events in CARDIoGRAMplusC4D (odds ratio 1.05; 95% CI [1.02, 1.07]; P = 1.4x10-4). In combined analysis across race/ethnic groups in MESA, rs10846744 was associated with Lp-PLA2 mass (P = 0.04) and activity (P = 0.001), homocysteine (P = 0.03), LDL particle number (P = 0.01), docosahexaenoic acid [DHA] (P = 0.01), docosapentaenoic acid [DPA] (P = 0.04), DPA/ eicosapentaenoic acid [EPA] ratio (P = 0.002), and DHA/EPA ratio (P = 0.008). Lp-PLA2 activity was identified as a mediator of rs10846744 with cIMT in a basic model (P = 8x10-5), but not after adjustment for CVD risk factors. There was no interaction or modifier effect of the Lp-PLA2 inhibitor darapladib assignment on the relationship between rs10846744 and major CVD events in either STABILITY or SOLID-TIMI 52. SUMMARY: SCARB1 rs10846744 is significantly associated with Lp-PLA2 activity, atherosclerosis, and CVD events, but Lp-PLA2 activity is not a mediator in the association of rs10846744 with cIMT in MESA.

AB - PURPOSE: Human papillomavirus (HPV) infected oropharyngeal squamous cell carcinoma (OPSCC) patients have a better prognosis compared to HPV(-) counterparts. However, a subset of HPV(+) patients with a smoking history fail to respond to the standard of care treatments such as radiation and chemotherapy. To understand the underlying mechanism driving HPV(+) OPSCC patient resistance to treatment and recurrence, we sought to identify and characterize the differentially expressed miRNAs and their target genes in HPV(+) smokers and non smokers. EXPERIMENTAL DESIGN: MicroRNA expression analysis was performed using Nanostring in tumor tissues isolated from a prospective cohort of HPV(+) smoking (n = 9) and HPV(+) (n = 13) non-smoking OPSCC patients. Identified miRNAs of interest were further validated using qRT-PCR in cigarette smoke extract (CSE) treated HPV(+) and E6/E7 overexpressing HPV(-) cells. RESULTS: In comparison to OPSCC HPV(+) non-smokers, 38 miRNAs were significantly altered in the HPV(+) smoker patients cohort and out of that 9 were downregulated. Altered miRNA expression was also detected in the serum and metastatic lymph nodes of HPV(+) smokers versus non-smokers. Expression of miR-133a-3p was significantly downregulated in OPSCC smokers, HPV(+) cells and E6/E7 overexpressing HPV(-) cells treated with CSE. Reduction of miR-133a-3p induced the upregulation of miR 133a-3p target mRNAs EGFR and HuR. CONCLUSIONS: Our results indicate that miR 133a-3p is a target of smoking-induced changes in HPV(+) patients and alters the expression of EGFR and HuR which may promote HPV associated oropharyngeal cancer. Therefore, future treatment strategies for HPV(+) OPSCC smokers should focus on EGFR inhibition and the development of selective therapies to target HuR.

AB - Under certain conditions, amyloid-like fibrils can develop into three-dimensional networks and form hydrogels by a self-assembly process. When Cu/Zn superoxide dismutase (SOD1), an anti-oxidative enzyme, undergoes misfolding, fibrillar aggregates are formed, which are a hallmark of a certain form of familial amyotrophic lateral sclerosis (ALS). However, the issue of whether SOD1 fibrils can be assembled into hydrogels remains to be tested. Here, we show that the SOD1 polypeptides undergo hydrogelation accompanied by the formation of thioflavin T positive fibrils at pH 3.0 and 4.0, but not at pH 5.0 where precipitates are formed. The results of viscoelastic analyses indicate that the properties of SOD1 hydrogels (2%) were similar to and slightly more fragile than a 0.25% agarose gel. In addition, monitoring by a quartz crystal microbalance with admittance analysis showed that the denaturing of immobilized SOD1 on a sensor under the hydrogelation conditions at pH 3.0 and 4.0 resulted in an increase in the effective acoustic thickness from ~3.3 nm (a folded rigid form) to ~50 and ~100 nm (an extended water-rich state), respectively. In contrast, when SOD1 was denatured under the same conditions at pH 5.0, a compact water-poor state with an effective acoustic thickness of ~10 nm was formed. The addition of physiological concentrations of NaCl to the pH 4.0 sample induced a further extension of the SOD1 with larger amounts of water molecules (with an effective acoustic thickness of ~200 nm) but suppressed hydrogel formation. These results suggest that different denatured intermediate states of the protein before self-assembly play a major role in determining the characteristics of the resulting aggregates and that a conformational change to a suitable level of extended water-rich intermediate state before and/or during intermolecular assembling is required for fibrillation and hydrogelation in the case of globular proteins.

AB - The brown planthopper (BPH), Nilaparvata lugens, is a serious threat to rice production in Vietnam and insecticides are widely used for its control. Migration of the BPH have one of its roots in tropical Vietnam in the Mekong River Delta and the insecticide resistance status of BPH populations from Vietnam is thus important for East Asia. In the present investigation, we evaluate the susceptibility of BPH populations from nine provinces from the Red River Delta, the Central Coastal region and the Mekong River Delta of eight insecticides during 2015-17. BPH field populations of Vietnam have developed a low to moderate level of resistance to the neonicotinoids dinotefuran, nitenpyram and imidacloprid, the pyrethroid etofenprox, the anticholinesterase fenobucarb, as well as fipronil and pymetrozine, and the growth regulator buprofezin. There was a correlation of in toxicology of fipronil, dinotefuran, etofenprox, buprofezin, which represents four different modes of action. The neonicotinoid nitenpyram, pymetrozine and fenobucarb did not show correlation in toxicology to any of the investigated insecticides. For most insecticides, a gradient of susceptibility was established from the Red River Delta in the north, through the Central Coastal region and to the Mekong River Delta in the south of Vietnam. The most susceptible populations were from the north. Insecticide resistance of the BPH populations in Vietnam is not at an alarming level and they are not the direct origin of high insecticide resistance found in East Asia. The cross-resistance pattern of BPH populations in Vietnam, where insecticides with different modes of action correlated, indicate that insecticides should be used with caution. There could be a buildup of a general metabolic resistance, which alone or in combination with the emergence of target-site resistance mutations will cause control problems. The results will be beneficial for development of resistance management strategies to prevent and delay development of insecticide resistance in BPH not only for Vietnam, but also for more northern Asian regions due the migration of BPH from tropical Vietnam. PMID- 30289954 TI - Dual biomarkers long non-coding RNA GAS5 and microRNA-34a co-expression signature in common solid tumors. AB - Accumulating evidence indicates that non-coding RNAs including microRNAs (miRs) and long non-coding RNAs (lncRNAs) are aberrantly expressed in cancer, providing promising biomarkers for diagnosis, prognosis and/or therapeutic targets. We aimed in the current work to quantify the expression profile of miR-34a and one of its bioinformatically selected partner lncRNA growth arrest-specific 5 (GAS5) in a sample of Egyptian cancer patients, including three prevalent types of cancer in our region; renal cell carcinoma (RCC), glioblastoma (GB), and hepatocellular carcinoma (HCC) as well as to correlate these expression profiles with the available clinicopathological data in an attempt to clarify their roles in cancer. Quantitative real-time polymerase chain reaction analysis was applied. Different bioinformatics databases were searched to confirm the potential miRNAs lncRNA interactions of the selected ncRNAs in cancer pathogenesis. The tumor suppressor lncRNA GAS5 was significantly under-expressed in the three types of cancer [0.08 (0.006-0.38) in RCC, p <0.001; 0.10 (0.003-0.89) in GB, p < 0.001; and 0.12 (0.015-0.74) in HCC, p < 0.001]. However, levels of miR-34a greatly varied according to the tumor type; it displayed an increased expression in RCC [4.05 (1.003-22.69), p <0.001] and a decreased expression in GB [0.35 (0.04 0.95), p <0.001]. Consistent to the computationally predicted miRNA-lncRNA interaction, negative correlations were observed between levels of GAS5 and miR 34a in RCC samples (r = -0.949, p < 0.001), GB (r = -0.518, p < 0.001) and HCC (r = -0.455, p = 0.013). Kaplan-Meier curve analysis revealed that RCC patients with down-regulated miR-34a levels had significantly poor overall survival than their corresponding (p < 0.05). Hierarchical clustering analysis showed RCC patients could be clustered by GAS5 and miR-34a co-expression profile. Our results suggest potential applicability of GAS5 and miR-34a with other conventional markers for various types of cancer. Further functional validation studies are warranted to confirm miR-34a/GAS5 interplay in cancer. PMID- 30289951 TI - Pathologic findings and causes of death of stranded cetaceans in the Canary Islands (2006-2012). AB - This study describes the pathologic findings and most probable causes of death (CD) of 224 cetaceans stranded along the coastline of the Canary Islands (Spain) over a 7-year period, 2006-2012. Most probable CD, grouped as pathologic categories (PCs), was identified in 208/224 (92.8%) examined animals. Within natural PCs, those associated with good nutritional status represented 70/208 (33.6%), whereas, those associated with significant loss of nutritional status represented 49/208 (23.5%). Fatal intra- and interspecific traumatic interactions were 37/208 (17.8%). Vessel collisions included 24/208 (11.5%). Neonatal/perinatal pathology involved 13/208 (6.2%). Fatal interaction with fishing activities comprised 10/208 (4.8%). Within anthropogenic PCs, foreign body-associated pathology represented 5/208 (2.4%). A CD could not be determined in 16/208 (7.7%) cases. Natural PCs were dominated by infectious and parasitic disease processes. Herein, our results suggest that between 2006 and 2012, in the Canary Islands, direct human activity appeared responsible for 19% of cetaceans deaths, while natural pathologies accounted for 81%. These results, integrating novel findings and published reports, aid in delineating baseline knowledge on cetacean pathology and may be of value to rehabilitators, caregivers, diagnosticians and future conservation policies.

AB - INTRODUCTION: Cardiac surgery with the use of cardiopulmonary bypass is known to induce distinct metabolic changes. Respective changes in acid-base status including increased systemic lactate levels were previously related to clinical outcomes, but data remain controversial. Therefore, we aim to investigate the relevance of lactate and base excess (BE) levels on ICU-mortality in patients admitted to the ICU after cardiac surgery. MATERIALS AND METHODS: Perioperative data of patients treated in a tertiary care academic center admitted to the ICU after on-pump surgery were analyzed in a retrospective fashion. Receiver operation characteristic (ROC) curves were constructed for admission lactate levels and BE with calculation of optimal cut-off values to predict ICU mortality. Univariate followed by multivariate regression models were constructed to identify potential outcome-relevant indices. RESULTS: Data from 1,058 patients were included in the analysis. Area under the curves for prediction of ICU mortality were 0.79 for lactate levels at ICU admission (sensitivity 61.9%/ specificity 87.5%; optimal cut-off level 3.9mmol/l), and 0.7 for BE (sensitivity 52.4%/ specificity 93.8%, optimal cut-off level -6.7), respectively. Multivariate regression identified BE < -6.7 as the single metabolic predictor of ICU mortality (HR 4.78, 95%-CI 1.4-16.33, p = 0.01). Explorative subgroup analyses revealed that the combination of lactate <=3.9mmol/l and BE <= -6.7 has stronger impact on mortality than a combination of lactate of >3.9mmol/l and BE > -6.7 (HR 2.56, 95%-CI 0.18-37.17). CONCLUSIONS: At ICU-admission, severely reduced BE appears superior to hyperlactatemia with regard to prediction of ICU-mortality in patients after cardiac surgery.

AB - OBJECTIVES: To evaluate associations between high-density lipoprotein cholesterol (HDL) and non-HDL-C levels at specific ages and subsequent Alzheimer's disease (AD) risk. DESIGN: Prospective population-based cohort study. SETTING: Adult Changes in Thought (ACT) Study. PARTICIPANTS: Individuals aged 65 and older with no dementia at ACT Study entry. We identified separate, partially overlapping subcohorts of ACT participants who were eligible for each age band-specific analysis (50-59, n = 1,088; 60-69, n = 2,852; 70-79, n = 2,344; 80-89, n = 537). MEASUREMENTS: Exposure consisted of clinical measures of total cholesterol (TC) and HDL-C from laboratory data during a given age band. Outcomes of incident AD were assessed post-age band using standard research diagnostic criteria. Statistical analyses used adjusted Cox proportional hazards regression models for each exposure and outcome pair within an age band. Cholesterol exposures were modeled using cubic splines. RESULTS: For non-HDL-C, we found a statistically significant association with AD risk in the 60 to 69 (omnibus p = .005) and 70 to 79 (omnibus p = .04) age bands, suggesting a potential U-shaped relationship (greater risk at low and high levels). For example, in people aged 60 to 69, those with an average non-HDL-C level of 120 mg/DL had a 29% greater AD hazard (hazard ratio (HR)=1.29, 95% confidence interval (CI)=1.04-1.61) than those with an average non-HDL-C level of 160 mg/dL, whereas those with an average non-HDL-C level of 210 mg/dL had a 16% greater hazard (HR=1.16, 95% CI=1.01-1.33). We did not find a statistically significant association between HDL-C and AD risk. CONCLUSION: People with low (120 mg/dL) and high (210 mg/dL) non-HDL-C levels during their 60s and 70s had modestly higher risk of AD than those with intermediate (160 mg/dL) levels. The extreme age bands (50s and 80s) had small sample sizes. PMID- 30289960 TI - Reply to Comment on "Personality Changes During the Transition from Cognitive Health to Mild Cognitive Impairment".

AB - OBJECTIVES: To estimate the incremental direct medical care costs associated with first fracture observable in high-risk older adults. DESIGN: Retrospective analysis of claims and survey data over a 3-year period from the Health and Retirement Study (HRS), a nationally representative biennial study of individuals aged 50 and older. SETTING: United States. PARTICIPANTS: Participants were HRS respondents who consented to have their Medicare claims data linked to the HRS data, were aged 65 or older, had at least 1 risk factor for fracture observable in the data, and experienced a fracture between 1996 and 2008 (n = 689) and their propensity score-matched controls (n = 689). MEASUREMENTS: Total Medicare, inpatient, outpatient, emergency department, physician office visit, and prescription drug care expenditures were primary outcomes. Two-staged generalized linear models were estimated using a difference-in-differences model. RESULTS: Fracture cases' total Medicare expenditures increased by $13,929 (95% confidence interval (CI)=$11,920-15,938, p <.001) more than those of matched controls from the year before the index or fracture date to 1 year after the index date. Inpatient expenditures of $12,751 (95% CI=$10,790-14,7111, p < .001) more for fracture cases than comparison cases primarily drove this increase. Two and 3 years after fracture, there were no significant differences in growth in expenditures between the two groups. Results did not vary according to whether the fracture was at the hip or other site. CONCLUSION: Fractures impose a significant economic burden, especially in the first year after the fracture, in Medicare beneficiaries with at least 1 risk factor for fracture. Our sample was limited to community-dwelling individuals, and we are unable to control for fracture history before the study period. Costs may be greater for those in skilled nursing and similar facilities and for those who have had a previous fracture.

AB - Resistance to radiotherapy and to EGFR tyrosine kinase inhibitors (EGFR-TKIs), as well as therapy-related lung toxicity, are serious problems in the treatment of lung cancer. NF-kappaB has been reported to be associated with radioresistance. Therefore, we evaluated its effects on sensitivity to irradiation and to EGFR TKIs; irradiation-induced lung toxicity; and the effects of irradiation on sensitivity to EGFR-TKIs. We used IKKbeta inhibitor IMD 0354 or p65 depletion to explore their effects on sensitivity to irradiation and to EGFR-TKIs in vitro and in vivo. We evaluated the efficacy of IMD 0354 in a radiation-induced pulmonary fibrosis mouse model. Irradiation enhanced activation and expression of MET and therefore suppressed the sensitivity of lung cancer cells to irradiation or EGFR TKIs. Inhibition of NF-kappaB by IMD 0354 or by p65 depletion reversed irradiation-induced MET activation and increased the sensitivity of lung cancer cells to irradiation, to EGFR-TKIs and to the combination thereof in vitro and in vivo. In addition, IMD 0354 significantly reduced lung toxicity in a murine model of irradiation-induced pneumonia and lung fibrosis. These findings indicated that NF-kappaB inhibition can improve sensitivity to irradiation and to EGFR-TKIs and can decrease irradiation-induced lung toxicity in lung cancer.

AB - Many studies have shown that flavan-3-ols inhibit mammalian alpha-amylases but the published IC50 and Ki values vary up to a thousand times. We therefore tested the effects of 6 pure flavan-3-ols-abundant in green tea-on the activity of pure porcine pancreatic alpha-amylase (PPA) under steady-state kinetic conditions. We used both amylose and maltopentaose as substrates, along with spectrophotometry and chromatography as analytical tools, respectively. A Docking approach was also used to probe the interaction between PPA and each flavan-3-ol. The results showed that the 6 flavan-3-ols inhibit amylose hydrolysis with Ki comprised between 7 and 34 MUM, according to a mixed inhibition profile for gallocatechin gallate, and a competitive inhibition profile for the 5 other flavanols. Only the galloyl-containing flavan-3-ols inhibited the maltopentaose hydrolysis with a Ki of about 30 MUM according to a noncompetitive profile. We conclude that dietary flavan-3-ols could inhibit starch digestion nonnegligibly. The results of the docking trials were concordant with the kinetic data and have noticeably revealed that the cis-flavan-3-ols epigallocatechin gallate and epicatechin gallate bind similarly to PPA, involving pi-stacking with Trp59.

PMID- 30289966 TI - Frequent PTEN loss and differential HER2/PI3K signaling pathway alterations in salivary duct carcinoma: Implications for targeted therapy. AB - BACKGROUND: Patients with advanced primary and recurrent salivary duct carcinoma (SDC), a rare and lethal malignancy, have limited therapeutic options. Novel small-molecule agents aimed at targeting critical signaling associated with SDC tumorigenesis may lead to new therapeutic options for patients with these tumors. The human epidermal growth factor receptor 2 (HER2)/phosphoinositide 3-kinase (PI3K) axis, an important oncogenic pathway, has been targeted for therapy in several solid tumors. Currently, little is known about the role and clinical implications of alterations of the HER2/PI3K pathway in patients with SDC. METHODS: The authors investigated the clinicopathologic features, genetic alterations, and expression of key members of the HER2/PI3K pathway in 43 primary tumors and conducted in vitro functional and targeted drug-response analyses on cell lines derived from salivary epithelial carcinomas. RESULTS: In primary tumors, loss of phosphatase and tensin homolog (PTEN) expression was identified in 22 of 43 tumors (51%), overexpression of HER2 was observed in 12 of 43 tumors (28%), and phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) mutations were identified in 12 of 43 tumors (28%). Phosphorylated protein kinase B (p-AKT) was highly expressed in most tumors. Most tumors (70%) displayed mutually exclusive alterations of PI3K members, whereas 8 tumors (19%) had 2 or more concurrent abnormalities. In vitro studies demonstrated a direct association between PTEN loss and PI3K pathway activation and evidence of response to combined PI3Kalpha and PI3Kbeta and/or pan-PI3K inhibitors. CONCLUSIONS: The current analyses reveal frequent PTEN loss and mutually exclusive alterations of key PI3K pathway members in SDC and demonstrate in vitro evidence of a response to pan-PI3K inhibitors. These results provide a framework for a biomarker-based substratification of patients with SDC in future targeted therapy. Cancer 2018;124:3523-32. (c) 2018 American Cancer Society.

AB - OBJECTIVES: To describe an innovative model of care, the Surgery Wellness Program (SWP), that uses a multidisciplinary team to develop and implement preoperative care plans for older adults, and its effect on engagement in advance care planning (ACP). DESIGN: Retrospective analysis of clinical demonstration project. SETTING: Preoperative optimization program for older adults undergoing surgery at a 796-bed academic tertiary hospital. PARTICIPANTS: Older adults (N=131) who participated in the SWP from February 2015 to August 2017. INTERVENTION: All SWP participants met with a geriatrician who engaged them in a semistructured ACP discussion. Trained medical and nurse practitioner students were used as health coaches who contacted participants regularly to address and document ACP. MEASUREMENTS: Self-report of ACP engagement before and after participation in the SWP was determined using SWP geriatrician and health coach progress notes. Medical records were examined for scanned documentation. Feasibility data on number of health coach calls were collected. RESULTS: After completion of the program, the proportion of participants with a designated surrogate increased from 67% to 78% (p<.001), completed advance directive (AD) from 51% to 72% (p<.001), and an AD scanned into the medical record from 14% to 60% (p<.001). Participants who underwent surgery received a median of 4 health coaching calls over a median of 27 days between their clinic visit and surgery. Case examples are presented to highlight how the SWP attends to the many components of the ACP process. CONCLUSION: Preoperative optimization programs provide a unique opportunity to engage older adults in ACP. PMID- 30289970 TI - Low Clinical Trial Accrual of Patients With Myelodysplastic Syndromes: Causes and Potential Solutions. AB - Despite few effective therapies, only a small percentage of patients diagnosed with myelodysplastic syndromes (MDS) in the United States are enrolled in prospective, interventional clinical trials. MDS-specific barriers to trial accrual include a high frequency of elderly patients with comorbid conditions, atypical disease features and uncertainty regarding the diagnosis (because other nonclonal processes also can cause dysplasia and cytopenias), a history of another nonmyeloid neoplasm resulting in therapy-related MDS, rapid disease recurrence after allogeneic stem cell transplantation, and an arbitrary division between MDS and acute myeloid leukemia. In addition, barriers to accrual that are common to other oncology populations, such as difficulty traveling to clinical trial enrollment sites and narrow trial eligibility criteria, also prevent patients with MDS from enrolling in studies. Collectively these barriers must be assessed systematically, and creative solutions are needed to improve outcomes for this needy patient population. PMID- 30289971 TI - Association between treatment of superficial bladder cancer and 10-year mortality in older adults with multiple chronic conditions. AB - BACKGROUND: Multiple chronic conditions (MCC) are common among older patients with cancer; however, the exclusion of these patients from clinical trials has resulted in scarce knowledge concerning outcomes, resulting in variations in treatment. Superficial bladder cancer (SBC) disproportionately affects older adults, yet to the authors' knowledge few studies to date have examined whether treatment improves long-term survival. In the current study, the authors evaluated the association between treatment of SBC and 10-year mortality in medically complex older adults. METHODS: The authors identified 1800 older (aged >=60 years) patients with SBC (American Joint Committee on Cancer stage <=I) from 2 community-based health systems who received treatment (bladder instillation and/or transurethral resection) or observation. Cox proportional hazards regression was performed adjusting for age, sex, race, health system, stage of disease/grade, and MCC (>=2 baseline chronic conditions). Propensity score analysis using stabilized inverse probability of treatment weights was used to compare 10-year mortality in the 2 treatment groups with adjustment for covariates. RESULTS: Overall, 1485 patients (82.5%) and 315 patients (17.5%) received treatment and observation, respectively. In unweighted multivariable analysis, treatment was associated with a 30% reduction in death (adjusted hazard ratio [HR], 0.70; 95% confidence interval [95% CI], 0.58-0.85 [P<.01]) and MCC with a 72% increase in death (adjusted HR, 1.72; 95% CI, 1.44-2.05 [P<.01]). Weighted analysis with adjustment (doubly robust) also demonstrated a survival benefit for treatment (adjusted HR, 0.66; 95% CI, 0.52-0.84 [P<.01]). CONCLUSIONS: The results of the current study demonstrated a clinically meaningful association between cancer treatment and survival benefit in older, medically complex patients with SBC, even after adjustment for medical complexity. These data provide a foundation for future work aimed at personalizing the treatment guidance of older patients with cancer with MCC. PMID- 30289973 TI - CINP is a novel cofactor of KLF5 required for its role in the promotion of cell proliferation, survival and tumor growth. AB - Kruppel-like factor 5 (KLF5) both suppresses and promotes tumor growth depending on cellular context. The mechanisms underlying tumor promotion could be targetable for therapy. Although a number of transcriptional targets of KLF5 have been identified and implicated in KLF5-mediated tumor growth, how KLF5 regulates these genes remains to be addressed. Here we performed coimmunoprecipitation (co IP) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) in the TSU-Pr1 bladder cancer cell line, in which KLF5 is shown to promote tumor growth, to identify KLF5-interacting nuclear proteins that are necessary for KLF5's tumor promoting function. LC-MS/MS revealed 122 potential KLF5 binding proteins in the nuclear proteins precipitated by the KLF5 antibody, and the top nine candidates included AHNAK, TFAM, HSDL2, HNRNPC, CINP, IST1, FBL, PABPC1 and SNRNP40. SRB assays of these nine proteins indicated that silencing CINP had the most potent inhibitory effect on cell growth in KLF5-expressing cells but did not affect parental TSU-Pr1 cells. Further analyses not only confirmed the physical interaction between KLF5 and CINP, also demonstrated that knockdown of CINP attenuated the effects of KLF5 on cell cycle progression, apoptosis and tumorigenesis. Silencing CINP also attenuated the effect of KLF5 on the expression of a number of genes and signaling pathways, including cell cycle regulator Cyclin D1 and apoptosis-related Caspase 7. These results suggest that CINP is a cofactor of KLF5 that is crucial for the promotion of tumor growth, and that the KLF5-CINP interaction could be a novel therapeutic target for inhibiting KLF5-promoted tumor growth.

AB - There is a major, unmet need for the treatment of cancer pain, and new targets and medicines are required. The transient receptor potential ankyrin 1 (TRPA1), a cation channel expressed by nociceptors, is activated by oxidizing substances to mediate pain-like responses in models of inflammatory and neuropathic pain. As cancer is known to increase oxidative stress, the role of TRPA1 was evaluated in a mouse model of cancer pain. Fourteen days after injection of B16-F10 murine melanoma cells into the plantar region of the right hind paw, C57BL/6 mice exhibited mechanical and thermal allodynia and thigmotaxis behavior. While heat allodynia was partially reduced in TRP vanilloid 1 (TRPV1)-deficient mice, thigmotaxis behavior and mechanical and cold allodynia were absent in TRPA1 deficient mice. Deletion of TRPA1 or TRPV1 did not affect cancer growth. Intrathecal TRPA1 antisense oligonucleotides and two different TRPA1 antagonists (HC-030031 or A967079) transiently attenuated thigmotaxis behavior and mechanical and cold allodynia. A TRPV1 antagonist (capsazepine) attenuated solely heat allodynia. NADPH oxidase activity and hydrogen peroxide levels were increased in hind paw skin 14 days after cancer cell inoculation. The antioxidant, alpha lipoic acid, attenuated mechanical and cold allodynia and thigmotaxis behavior, but not heat allodynia. Whereas TRPV1, via an oxidative stress-independent pathway, contributes partially to heat hypersensitivity, oxidative stress dependent activation of TRPA1 plays a key role in mediating thigmotaxis behavior and mechanical and cold allodynia in a cancer pain model. TRPA1 antagonists might be beneficial in the treatment of cancer pain. PMID- 30289974 TI - Reduced expression of the ferroptosis inhibitor glutathione peroxidase-4 in multiple sclerosis and experimental autoimmune encephalomyelitis. AB - Glutathione peroxidase 4 (GPx4) is the only enzyme capable of reducing toxic lipid hydroperoxides in biological membranes to the corresponding alcohols using glutathione as the electron donor. GPx4 is the major inhibitor of ferroptosis, a non-apoptotic and iron-dependent programmed cell death pathway, which has been shown to occur in various neurological disorders with severe oxidative stress. In this study, we investigate whether GPx4 expression is altered in multiple sclerosis and its animal model experimental autoimmune encephalomyelitis (EAE). The results clearly show that mRNA expression for all three GPx4 isoforms (cytoplasmic, mitochondrial and nuclear) decline in multiple sclerosis gray matter and in the spinal cord of MOG35-55 peptide-induced EAE. The amount of GPx4 protein is also reduced in EAE, albeit not in all cells. Neuronal GPx4 immunostaining, mostly cytoplasmic, is lower in EAE spinal cords than in control spinal cords, while oligodendrocyte GPx4 immunostaining, mainly nuclear, is unaltered. Neither control nor EAE astrocytes and microglia cells show GPx4 labeling. In addition to GPx4, two other negative modulators of ferroptosis (gamma-glutamylcysteine ligase and cysteine/glutamate antiporter), which are critical to maintain physiological levels of glutathione, are diminished in EAE. The decrease in the ability to eliminate hydroperoxides was also evidenced by the accumulation of lipid peroxidation products and the reduction in the proportion of the docosahexaenoic acid in non-myelin lipids. These findings, along with presence of abnormal neuronal mitochondria morphology, which includes an irregular matrix, disrupted outer membrane and reduced/absent cristae, are consistent with the occurrence of ferroptotic damage in inflammatory demyelinating disorders. PMID- 30289976 TI - Proteomics of neurodegenerative diseases: analysis of human post-mortem brain. AB - Dementias are prevalent brain disorders in the aged population. Dementias pose major socio-medical burden, but currently there is no cure available. Novel proteomics approaches hold promise to identify alterations of the brain proteome that could provide clues on disease etiology, and identify candidate proteins to develop further as a biomarker. In this review, we focus on recent proteomics findings from brains affected with Alzheimer's Disease, Parkinson Disease Dementia, Frontotemporal Dementia, and Amyotrophic Lateral Sclerosis. These studies confirmed known cellular changes, and in addition identified novel proteins that may underlie distinct aspects of the diseases. PMID- 30289975 TI - The impact of obesity and bariatric surgery on circulating and tissue biomarkers of endometrial cancer risk. AB - Obesity is the strongest risk factor for endometrial cancer (EC). To inform targeted screening and prevention strategies, we assessed the impact of obesity and subsequent bariatric surgery-induced weight loss on endometrial morphology and molecular pathways implicated in endometrial carcinogenesis. Blood and endometrial tissue were obtained from women with class III-IV obesity (body mass index >=40 and >=50 kg/m2 , respectively) immediately prior to gastric bypass or sleeve gastrectomy, and at two and 12 months' follow up. The endometrium underwent pathological examination and immunohistochemistry was used to quantify proliferation (Ki-67), oncogenic signaling (PTEN, pAKT, pERK) and hormone receptor (ER, PR) expression status. Circulating biomarkers of insulin resistance, reproductive function and inflammation were also measured at each time point. Seventy-two women underwent bariatric surgery. At 12 months, the mean change in total and excess body weight was -32.7 and -62.8%, respectively. Baseline endometrial biopsies revealed neoplastic change in 10 women (14%): four had EC, six had atypical hyperplasia (AH). After bariatric surgery, most cases of AH resolved (5/6) without intervention (3/6) or with intrauterine progestin (2/6). Biomarkers of endometrial proliferation (Ki-67), oncogenic signaling (pAKT) and hormone receptor status (ER, PR) were significantly reduced, with restoration of glandular PTEN expression, at 2 and 12 months. There were reductions in circulating biomarkers of insulin resistance (HbA1c, HOMA-IR) and inflammation (hsCRP, IL-6), and increases in reproductive biomarkers (LH, FSH, SHBG). We found an unexpectedly high prevalence of occult neoplastic changes in the endometrium of women undergoing bariatric surgery. Their spontaneous reversal and accompanying down-regulation of PI3K-AKT-mTOR signaling with weight loss may have implications for screening, prevention and treatment of this disease. PMID- 30289977 TI - Thioridazine inhibits autophagy and sensitizes glioblastoma cells to temozolomide. AB - Glioblastoma multiforme (GBM) has a poor prognosis with an overall survival of 14 15 months following surgery, radiation and chemotherapy using temozolomide (TMZ). A major problem is that the tumors acquire resistance to therapy. In an effort to improve the therapeutic efficacy of TMZ, we performed a genome-wide RNA interference (RNAi) synthetic lethality screen to establish a functional gene signature for TMZ sensitivity in human GBM cells. We then queried the Connectivity Map database to search for drugs that would induce corresponding changes in gene expression. By this approach we identified several potential pharmacological sensitizers to TMZ, where the most potent drug was the established antipsychotic agent Thioridazine, which significantly improved TMZ sensitivity while not demonstrating any significant toxicity alone. Mechanistically, we show that the specific chemosensitizing effect of Thioridazine is mediated by impairing autophagy, thereby preventing adaptive metabolic alterations associated with TMZ resistance. Moreover, we demonstrate that Thioridazine inhibits late-stage autophagy by impairing fusion between autophagosomes and lysosomes. Finally, Thioridazine in combination with TMZ significantly inhibits brain tumor growth in vivo, demonstrating the potential clinical benefits of compounds targeting the autophagy-lysosome pathway. Our study emphasizes the feasibility of exploiting drug repurposing for the design of novel therapeutic strategies for GBM. This article is protected by copyright. All rights reserved. PMID- 30289979 TI - Landscape heterogeneity strengthens the relationship between beta-diversity and ecosystem function. AB - Consensus has emerged in the literature that increased biodiversity enhances the capacity of ecosystems to perform multiple functions. However, most biodiversity/ecosystem function studies focus on a single ecosystem, or on landscapes of homogenous ecosystems. Here, we investigate how increased landscape level environmental dissimilarity may affect the relationship between different metrics of diversity (alpha, beta, or gamma) and ecosystem function. We produced a suite of simulated landscapes, each of which contained four experimental outdoor aquatic mesocosms. Differences in temperature and nutrient conditions of the mesocosms allowed us to simulate landscapes containing a range of within landscape environmental heterogeneities. We found that the variation in ecosystem functions was primarily controlled by environmental conditions, with diversity metrics accounting for a smaller (but significant) amount of variation in function. When landscapes were more homogeneous, alpha, beta, and gamma diversity was not associated with differences in primary production, and only gamma was associated with changes in decomposition. In these homogeneous landscapes, differences in these two ecosystem functions were most strongly related to nutrient and temperature conditions in the ecosystems. However, as landscape level environmental dissimilarity increased, the relationship between alpha, beta, or gamma and ecosystem functions strengthened, with beta being a greater predictor of variation in decomposition at the highest levels of environmental dissimilarity than alpha or gamma. We propose that when all ecosystems in a landscape have similar environmental conditions, species sorting is likely to generate a single community composition that is well suited to those environmental conditions, beta is low, and the efficiency of diversity-ecosystem function couplings is similar across communities. Under this low beta, the effect of abiotic conditions on ecosystem function will be most apparent. However, when environmental conditions vary among ecosystems, species sorting pressures are different among ecosystems, producing different communities among locations in a landscape. These conditions lead to stronger relationships between beta and the magnitude of ecosystem functions. Our results illustrate that abiotic conditions and the homogeneity of communities influence ecosystem function expressed at the landscape scale. PMID- 30289978 TI - LKB1 regulates PRMT5 activity in breast cancer. AB - Protein arginine methyltransferase 5 (PRMT5) is the main enzyme responsible for the symmetrical dimethylation of arginine residues on target proteins in both the cytoplasm and the nucleus. Though its activity has been associated with tumor progression in various cancers, the expression pattern of this oncoprotein has been scarcely studied in breast cancer. In the current work, we analyzed its expression in a large cohort of breast cancer patients, revealing higher nuclear PRMT5 levels in ERalpha-positive tumors and an association with prolonged disease free and overall survival. Interestingly, high PRMT5 nuclear expression was also associated with higher nuclear liver kinase B1 (LKB1), suggesting that a functional relationship may occur. Consistently, several approaches provided evidence that PRMT5 and LKB1 interact directly in the cytoplasm of mammary epithelial cells. Moreover, although PRMT5 is not able to methylate LKB1, we found that PRMT5 is a bona fade substrate for LKB1. We identified T132, 139 and 144 residues, located in the TIM-Barrel domain of PRMT5, as target sites for LKB1 phosphorylation. The point mutation of PRMT5 T139/144 to A139/144 drastically decreased its methyltransferase activity, due probably to the loss of its interaction with regulatory proteins such as MEP50, pICln and RiOK1. In addition, modulation of LKB1 expression modified PRMT5 activity, highlighting a new regulatory mechanism that could have clinical implications. PMID- 30289980 TI - What Do Transplant Physicians Think About Palliative Care? A National Survey Study. AB - BACKGROUND: Despite its established benefits, palliative care (PC) is rarely utilized for hematopoietic stem cell transplant (HSCT) patients. We sought to examine transplant physicians' perceptions of PC. METHODS: We conducted a cross sectional survey of transplant physicians recruited from the American-Society-for Blood-and-Marrow-Transplantation. Using a 28-item questionnaire adapted from prior studies, we examined physicians' access to PC services, and perceptions of PC. We computed a composite score of physicians' attitudes about PC (mean = 16.9, SD = 3.37) and explored predictors of attitudes using a linear mixed model. RESULTS: 277/1005 (28%) of eligible physicians completed the questionnaire. The majority (76%) stated that they trust PC clinicians to care for their patients, but 40% felt that PC clinicians do not have enough understanding to counsel HSCT patients about their treatments. Most endorsed that when patients hear the term PC, they feel scared (82%) and anxious (76%). Nearly half (46%) reported that the service name 'palliative care' is a barrier to utilization. Female sex (beta = 0.85, P = .024), having <10 years of clinical practice (beta = 1.39, P = .004), and perceived quality of PC services (beta = 0.60, P < .001) were all associated with a more positive attitude towards PC. Physicians with a higher sense of ownership over their patients' PC issues (beta = -0.36, P < .001) were more likely to have a negative attitude towards PC. CONCLUSIONS: The majority of transplant physicians trust PC, but have substantial concerns about PC clinicians' knowledge about HSCT and patients' perception of the term 'palliative care'. Interventions are needed to promote collaboration, improve perceptions, and enhance integration of PC for HSCT recipients. PMID- 30289981 TI - Therapeutic activity of DCC-2036, a novel tyrosine kinase inhibitor, against triple-negative breast cancer patient-derived xenografts by targeting AXL/MET. AB - Triple-negative breast cancer (TNBC) is insensitive to endocrine therapies and targeted therapies to human epidermal growth factor receptor-2 (HER2), estrogen receptor (ER) and progesterone receptor (PR). New targets and new targeted therapeutic drugs for TNBC are desperately needed. Our study confirmed that DCC 2036 inhibited the proliferation, invasion, migration and epithelial-mesenchymal transition (EMT) of TNBC cells as well as induced apoptosis. Moreover, the antiproliferative activity of DCC-2036 was more efficient than that of most clinical drugs. In addition, the combination of DCC-2036 and cisplatin or lapatinib had synergistic effects on TNBC cells. Mechanistically, DCC-2036 targeted AXL/MET, especially AXL, and regulated the downstream PI3K/Akt-NFkappaB signaling to exert its antitumor effect in TNBC. DCC-2036 also inhibited the growth and metastasis of xenografted MDA-MB-231 cells (AXL/MET-high TNBC cells) but not MDA-MB-468 cells (AXL-low TNBC cells) in NSG mice in vivo. Furthermore, DCC-2036 significantly inhibited tumor growth and invasion of AXL/MET-high TNBC PDX tumors but not AXL/MET-low TNBC PDX tumors. These results highlighted the roles of AXL/MET in cancer growth and metastasis and further verified that the critical targets of DCC-2036 are AXL and MET, especially AXL. In addition, there was no significant toxicity of DCC-2036 even at a high dosage. Therefore, DCC 2036 may be a potential compound to treat TNBC, especially for tumors with AXL/MET overexpression. PMID- 30289982 TI - PNPLA3 and TM6SF2 variants as risk factors of hepatocellular carcinoma across various etiologies and severity of underlying liver diseases. AB - Few single nucleotide polymorphisms (SNPs) have been reproducibly associated with hepatocellular carcinoma (HCC). Our aim was to test the association between nine SNPs and HCC occurrence. SNPs in genes linked to HCC (DEPDC5, GRIK1, KIF1B, STAT4, MICA, DLC1, DDX18) or to liver damage (PNPLA3-rs738409, TM6SF2-rs58542926) in GWAS were genotyped in discovery cohorts including 1,020 HCC, 2,021 controls with chronic liver disease and 2,484 healthy individuals and replication was performed in prospective cohorts of cirrhotic patients with alcoholic liver disease (ALD, n = 249) and hepatitis C (n = 268). In the discovery cohort, PNPLA3 and TM6SF2 SNPs were associated with HCC (OR = 1.67 [CI95%:1.16-2.40], p = 0.005; OR = 1.45 [CI95%:1.08-1.94], p = 0.01) after adjustment for fibrosis, age, gender and etiology. In contrast, STAT4-rs7574865 was associated with HCC only in HBV infected patients (p = 0.03) and the other tested SNP were not linked with HCC risk. PNPLA3 and TM6SF2 variants were independently associated with HCC in patients with ALD (OR = 3.91 [CI95%:2.52-6.06], p = 1.14E-09; OR = 1.79 [CI95%:1.25-2.56], p = 0.001) but not with other etiologies. PNPLA3 SNP was also significantly associated with HCC developed on a nonfibrotic liver (OR = 2.19 [CI95%:1.22-3.92], p = 0.007). The association of PNPLA3 and TM6SF2 with HCC risk was confirmed in the prospective cohort with ALD. A genetic score including PNPLA3 and TM6SF2 minor alleles showed a progressive significant increased risk of HCC in ALD patients. In conclusion, PNPLA3-rs738409 and TM6SF2-rs58542926 are inherited risk variants of HCC development in patients with ALD in a dose dependent manner. The link between PNPLA3 and HCC on nonfibrotic liver suggests a direct role in liver carcinogenesis.

AB - BACKGROUND: Th17 cells have nonredundant roles in maintaining immunity, particularly at mucosal surfaces. These roles are achieved principally through the production of cytokines and the recruitment of other immune cells to maintain the integrity of mucosal barriers and prevent the dissemination of microorganisms. Th17 cells are heterogeneous and exhibit a considerable degree of plasticity. This allows these cells to respond to changing environmental challenges. However, Th17 cells also play pro-inflammatory roles in chronic autoimmune diseases. The trigger(s) that initiate these Th17 responses in chronic autoimmune diseases remain unclear. DESIGN: In this report, we provide an overview of studies involving animal models, patient data, genome wide association studies and clinical trials targeting IL-17 for treatment of patients to gain a better understanding of the pathogenic roles of Th17 cells play in a range of autoimmune diseases. RESULTS: The report sheds light on likely triggers that initiate or perpetuate Th17 responses that promote chronic inflammation and autoimmunity. The divergent effects of tumour necrosis factor alpha blockade on Th17 cells in patients, is explored. Furthermore, we highlight the role of Th17 cells in inducing autoreactive B cells, leading to autoantibody production. Pathogenic bacterial species can change Th17 cell phenotype and responses. These findings provide insights into how Th17 cells could be induced to promoting autoimmune disease pathogenesis. CONCLUSION: This article provides an overview of the distinct roles Th17 cells play in maintaining immunity at mucosal surfaces and in skin mucosa and how their functional flexibility could be linked with chronic inflammation in autoimmune rheumatic diseases. PMID- 30289987 TI - Visions of Eye Commensals: The Known and the Unknown About How the Microbiome Affects Eye Disease. AB - Until recently, the ocular surface is thought by many to be sterile and devoid of living microbes. It is now becoming clear that this may not be the case. Recent and sophisticated PCR analyses have shown that microbial DNA-based "signatures" are present within various ethnic, geographic, and contact lens wearing communities. Furthermore, using a mouse model of ocular surface disease, we have shown that the microbe, Corynebacterium mastitidis (C. mast), can stably colonize the ocular mucosa and that a causal relationship exists between ocular C. mast colonization and beneficial local immunity. While this constitutes proof-of concept that a bona fide ocular microbiome that tunes immunity can exist at the ocular surface, there remain numerous unanswered questions to be addressed before microbiome-modulating therapies may be successfully developed. Here, the authors will briefly outline what is currently known about the local ocular microbiome as well as microbiomes associated with other sites, and how those sites may play a role in ocular surface immunity. Understanding how commensal microbes affect the ocular surface immune homeostasis has the potential revolutionize how we think about treating ocular surface disease.

This review will also act as a guide and reference for researchers to explore promising applications in relevant research. PMID- 30289989 TI - Impact of all-oral direct-acting antivirals on clinical and economic outcomes in chronic hepatitis C patients in the U.S. AB - : Approved treatment for hepatitis C virus (HCV) with all-oral direct acting antivirals (DAA) therapy is now entering into its fourth year; however, little has been reported on the real world clinical [decompensated cirrhosis (DCC) and hepatocellular carcinoma (HCC)] and economic outcomes. A retrospective cohort analysis of the Truven Health MarketScan Database (2012 - 2016) was conducted. In a cohort of 26,105 newly diagnosed HCV patients, 30% received all-oral DAA therapy (DAA group) and 70% were not treated (untreated group). Multivariate Cox proportional hazards models were used to compare the risk of developing HCC and DCC, stratified by cirrhosis status. Among cirrhotic patients (n=2,157), DAA therapy was associated with a 72% and a 62% lower incidence of HCC (hazard ratio (HR): 0.28; 95% confidence interval (CI):0.15-0.52) and DCC (HR: 0.38; 95% CI: 0.26-0.56). Similarly, DAA therapy was associated with a 57% and a 58% lower incidence of HCC (HR: 0.43; 95% CI:0.26-0.71) and DCC (HR: 0.42; 95% CI: 0.30 0.58) in non-cirrhotic HCV patients (n=23,948). A propensity-score matched cohort of 8,064 HCV-infected patients who had at least a 12-month follow-up after HCV treatment was included for economic analysis. For cirrhotic patients in the DAA group, the mean adjusted liver-related costs ($1,749 vs $4,575; P<0.001) and all cause medical costs ($19,300 vs $33,039; P<0.001) were significantly lower compared to those in the untreated group. The mean adjusted costs were not statistically different between the two groups among non-cirrhotic patients. CONCLUSIONS: In the short term, all-oral DAA treatment for HCV infection was associated with a decreased risk of developing HCC and DCC resulting in decreased healthcare costs, especially in cirrhotic patients.

PMID- 30289991 TI - Proton pump inhibitors use and risk of hepatocellular carcinoma. AB - One cohort study using the Taiwan's database conducted by Kao et al published in Hepatology reported that proton pump inhibitors use was not associated with the risk of developing hepatocellular carcinoma in patients with chronic hepatitis B infection or chronic hepatitis C infection. The findings were compatible with our cohort analysis using the Taiwan's database showing no association between proton pump inhibitors use and hepatocellular carcinoma. In contrast, a recent case control study using the Taiwan's database conducted by Shao et al reported that proton pump inhibitors use might increase the risk of hepatocellular carcinoma in patients without hepatitis B infection or hepatitis C infection (odds ratio 2.86, 95% confidence interval 2.69-3.04).

AB - Accumulating evidence does not yet confirm the effect of power line frequency magnetic field (MF) on human health and fertility. We recently reported that, at continuous 60 Hz MF exposure in mice, the dose given as magnetic flux density (tesla; T) and duration of exposure was related to induce testicular germ cell apoptosis. We aimed to characterize the effect of a 20-week continuous exposure to 60 Hz MF on the motility, morphology, and number of sperm as well as the apoptosis of testicular germ cell in rats. Sprague-Dawley rats were exposed for 20 weeks to 60 Hz MF of 2, 20, or 200 MUT for 24 h/day with rats exposed to sham conditions, serving as the control. The exposure to 60 Hz MF of 2 and 20 MUT had no effects on testicular in this study. The exposure to 60 Hz MF of 200 MUT for 20 weeks induced increases of the apoptotic cells (P < 0.001) in germ cells and decreases of sperm numbers (P < 0.05). However, the MF did not significantly affect the body or testis mass, seminiferous tubule diameter, or the motility or morphology of sperm. This study concluded that exposure to 60 Hz MF of 200 MUT can increase testicular germ cell apoptosis, especially spermatogonia, and reduce sperm count. Also compared to previous mice studies, rats are less sensitive than mice to exposure to 60 Hz MF. Bioelectromagnetics. 39:539-546, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30289992 TI - Proton pump inhibitors are associated to minimal and overt hepatic encephalopathy and increase mortality in cirrhotics. AB - BACKGROUND: Minimal hepatic encephalopathy (MHE) is a subclinical cognitive impairment frequently observable in cirrhotics. Proton pump inhibitors (PPIs) can contribute to small-bowel bacterial overgrowth but no study investigated the link between PPIs and MHE. AIM: to investigate the relationship between minimal HE and PPIs use as well as the role of PPIs use in the development of overt HE and survival. PATIENTS AND METHODS: 310 consecutive cirrhotic patients were included in the study and followed up for 14.1+/-12.3 months. At entry, MHE was diagnosed when the Psychometric Hepatic Encephalopathy Score (PHES) was <= -4. Data were analyzed by logistic regression for the factors associated to MHE and by time related models for overt HE development and survival . RESULTS: at inclusion, 131 out of 310 cirrhotic patients (42%) were affected by MHE. One hundred and twenty five patients (40%) were using PPIs. The variables independently associated to the presence of MHE were: PPIs use, previous overt HE, low albumin, low sodium and age. During follow-up, the development of overt HE was higher (64% vs 25%; p<0.001) and overall survival lower (41% vs 81%; p<0.001) in PPIs users than in non-users. Variables independently associated to the development of overt HE were: PPIs, history of overt HE, low albumin, MHE and age while variables independently associated to mortality were: PPIs, development of overt HE, MELD score, age, low sodium and age. CONCLUSION: the study identifies a potentially removable factor associated to the presence of minimal HE and related to the development of overt HE and survival in patients with liver cirrhosis.

PMID- 30289993 TI - Custom edge-element FEM solver and its application to eddy-current simulation of realistic 2M-element human brain phantom. AB - Extensive research papers of three-dimensional computational techniques are widely used for the investigation of human brain pathophysiology. Eddy current analyzing could provide an indication of conductivity change within a biological body. A significant obstacle to current trend analyses is the development of a numerically stable and efficiency-finite element scheme that performs well at low frequency and does not require a large number of degrees of freedom. Here, a custom finite element method (FEM) solver based on edge elements is proposed using the weakly coupled theory, which separates the solution into two steps. First, the background field (the magnetic vector potential on each edge) is calculated and stored. Then, the electric scalar potential on each node is obtained by FEM based on Galerkin formulations. Consequently, the electric field and eddy current distribution in the object can be obtained. This solver is more efficient than typical commercial solvers since it reduces the vector eddy current equation to a scalar one, and reduces the meshing domain to just the eddy current region. It can therefore tackle complex eddy current calculations for models with much larger numbers of elements, such as those encountered in eddy current computation in biological tissues. An example is presented with a realistic human brain mesh of 2 million elements. In addition, with this solver, the equivalent magnetic field induced from the excitation coil is applied, and therefore there is no need to mesh the excitation coil. In combination, these significantly increase the efficiency of the solver. Bioelectromagnetics. 39:604 616, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30289995 TI - Suboptimal Clinical Response Rates with Newer Antibiotics Among Patients with Moderate Renal Impairment: Review of the Literature and Potential Pharmacokinetic and Pharmacodynamic Considerations for Observed Findings. AB - A number of antibacterial agents have emerged into the U.S. market in the last 2 decades to address growing concerns of antimicrobial resistance. These agents have demonstrated noninferiority to comparators for treatment of a range of complicated infections in their respective clinical trials. However, with select agents, a trend of reduced therapeutic efficacy was observed among study patients with baseline renal impairment. This phenomenon was seen in phase III studies involving ceftazidime-avibactam, ceftolozane-tazobactam, daptomycin, and telavancin. Although these were largely post hoc findings among small subpopulations, this observation is still concerning, given that renal impairment is a common occurrence among patients in real-world care settings. Cautions for use in this population are featured in the prescribing information of all four agents. Although well-defined reasons for these findings across trials are diverse or unknown, several potential pharmacokinetic and pharmacodynamic explanations for these discordant response rates exist. In this review, we summarize the phase III studies that observed lower response rates with ceftazidime-avibactam, ceftolozane-tazobactam, daptomycin, and telavancin relative to their comparators among patients with moderate renal impairment, discuss potential explanations for the observed findings, provide considerations for future antibiotic development, and offer strategies for optimizing antibiotic dosage selection among patients with moderate renal impairment in clinical settings. Although all of these agents are discussed, ceftazidime-avibactam is used as a motivating example to demonstrate the implications of inappropriate dosage selection. PMID- 30289994 TI - N-Acetylcysteine potentiates the haemodynamic-improving effect of sildenafil in a rabbit model of acute pulmonary thromboembolism via the p38 MAPK pathway. AB - The current study aimed to investigate the effects of sildenafil and N acetylcysteine (NAC) on the haemodynamics in a rabbit model of acute pulmonary thromboembolism (APT). We developed an APT model using healthy male China big-ear rabbits (2.7 +/- 0.4 kg). The rabbits were divided into five groups subjected to various interventions. We recorded the haemodynamic parameters and assessed the oxidative stress and lipid peroxidation response in the groups. Additionally, we detected apoptosis-associated molecules, FoxO1, Bad and Bcl-2, in the lung tissue. Gelatine zymography was used to detect matrix metalloproteinase (MMP) activity in bronchoalveolar lavage (BLA). Pulmonary artery endothelial cells were isolated, and their apoptosis rates and MMP activity were assayed. N acetylcysteine potentiated the haemodynamic-improving effect of sildenafil and significantly inhibited the oxidative stress response. N-acetylcysteine combined with sildenafil decreased MMP-2 and MMP-9 activity and NO consumption and inhibited apoptosis of pulmonary arterial endothelial cells. Moreover, NAC combined with sildenafil inhibited the expression of MCP-1 and p-p38 MAPK. Thus, NAC potentiates the haemodynamic-improving effect of sildenafil in a rabbit model of acute pulmonary thromboembolism via the MCP-1 and p38 MAPK signalling pathway. This study may provide a promising treatment method for APT. PMID- 30289996 TI - The antidepressant drug, sertraline, hinders bone healing and osseointegration in rats' tibiae. AB - AIM: Selective serotonin reuptake inhibitors (SSRIs) are one of the most common antidepressant drugs. SSRI use is associated with increased risk of bone fracture and titanium implant failure. The aim of this in vivo study was to investigate the effect of SSRIs on osseointegration and bone healing. MATERIALS AND METHODS: On a total of 24 Sprague-Dawley rats, a custom-made titanium implant was placed in the left tibia, while a unicortical defect was created in the right tibia. Rats were assigned randomly into two groups and received a daily dose of either sertraline (5 mg/kg) or saline. After two weeks, they were euthanized and bone healing and osseointegration were assessed by micro-CT and histology. RESULTS: Bone formation in bone defects was significantly lower (p < 0.05) in sertraline treated rats (BV/TV = 20.67 +/- 11.98%) compared to the controls (BV/TV = 37.87 +/- 9.56%). Furthermore, the percentage of osseointegration was significantly lower (p < 0.05) in sertraline-treated rats (34.40 +/- 7.17%) compared to the controls (54.37 +/- 8.58%). CONCLUSION: Sertraline hinders bone healing and implant osseointegration. PMID- 30289997 TI - Recent developments and highlights in biomarkers in allergic diseases and asthma. AB - The potential of precision medicine in allergy and asthma has only started to be explored. A significant clarification in the pathophysiology of rhinitis, chronic rhinosinusitis, asthma, food allergy and drug hypersensitivity was made in the last decade. This improved understanding led to a better classification of the distinct phenotypes and to the discovery of new drugs such as biologicals, targeting phenotype-specific mechanisms. Nevertheless, many conditions remain poorly understood such as non-eosinophilic airway diseases or non-IgE-mediated food allergy. Moreover, there is a need to predict the response to specific therapies and the outcome of drug and food provocations. The identification of patients at risk of progression towards severity is also an unmet need in order to establish adequate preventive or therapeutic measures. The implementation of precision medicine in the clinical practice requires the identification of phenotype-specific markers measurable in biological matrices. To become useful, these biomarkers need to be quantifiable by reliable systems, and in samples obtained in an easy, rapid and cost-efficient way. In the last years, significant research resources have been put in the identification of valid biomarkers for asthma and allergic diseases. This review summarizes these recent advances with focus on the biomarkers with higher clinical applicability. PMID- 30289998 TI - Association between periodontitis and risk of Alzheimer's disease, mild cognitive impairment and subjective cognitive decline: A case-control study. AB - AIMS: To test the hypothesis that periodontal disease contributes to increased risk of mild cognitive impairment (MCI), subjective cognitive decline (SCD) and Alzheimer's disease (AD). MATERIALS AND METHODS: This case-control study was conducted over a 3-year period in the municipality of Huddinge, Sweden. In total, 154 cases were consecutively enrolled from the Karolinska Memory Clinic at the Karolinska University Hospital and allotted to three diagnostic groups: AD, MCI and SCD, collectively referred to as "cases." Seventy-six cognitively healthy age and gender-matched controls were randomly sampled through the Swedish population register. All cases and controls underwent clinical and radiographic oral examinations. Statistical analysis was based on logistic regression models adjusted for potential confounders. RESULTS: Poor oral health and marginal alveolar bone loss were more prevalent among cases than among controls. The cases group was associated with generalized marginal alveolar bone loss (odds ratio [OR] = 5.81; 95% confidence interval [CI] = 1.14-29.68), increased number of deep periodontal pockets (OR = 8.43; CI 4.00-17.76) and dental caries (OR = 3.36; CI 1.20-9.43). CONCLUSION: The results suggest that marginal periodontitis is associated with early cognitive impairment and AD. However, the study design does not preclude noncausal explanations. PMID- 30289999 TI - Boron: the essential element for vascular plants that never was. AB - Although a requirement for boron is a well-established feature of vascular plants, its designation, for almost a century, as essential is challenged and, instead, the proposal is made that it has never been so as conventionally defined. This is because an alternative interpretation of published evidence negates its compliance with one of the criteria for essentiality, that its effects are direct. The alternative, here postulated, is that boron is, and always has been, potentially toxic, a feature which, for normal growth, development and reproduction, needed to be nullified. This was enabled by exploitation of boron's ability to be chemically bound to compounds with cis hydroxyl groups. Although particular cell wall carbohydrate polymers, glycoproteins and membrane glycolipids are among candidates for this role, it is here proposed that soluble phenolic metabolites of, or related to, the components of the pathway of lignin biosynthesis, themselves potentially toxic, are primarily used by vascular plants. When metabolic circumstances allow these phenolics to accumulate endogenously in the cytoplasm, their own inherent toxicity is also alleviated, partially at least, by formation of complexes with boron. This chemical reciprocity, enhanced by physical sequestration of the complexes in vacuoles and/or apoplast, thus achieves, in a flexible but indirect manner, a minimization of the inherent toxicities of both boron and relevant phenolics. In these ways, the multifarious outcomes of impairments, natural or experimental, to this interplay are responsible for the lack of consensus to explain the diverse effects observed in the many searches for boron's primary metabolic role, here considered to be nonexistent. In particular, since a toxic element cannot have 'deficiency symptoms', those previously so-called are postulated to be largely due to the expressed toxicity of phenylpropanoids. A principal requirement for the otherwise toxic boron is to nullify, by means of its indirect chemical and physical sequestration, such expression. In these ways, it is therefore neither an essential nor a beneficial element as currently strictly defined. PMID- 30290000 TI - Omadacycline Enters the Ring: A New Antimicrobial Contender. AB - Omadacycline is a novel aminomethylcycline approved for the treatment of community-acquired bacterial pneumonia and acute bacterial skin and skin structure infections. This article reviews existing data pertaining to the biochemistry, mechanism of action, pharmacokinetics/pharmacodynamics, in vitro activity, and current progress with omadacycline in clinical trials. Omadacycline inhibits protein synthesis by binding to the 30S subunit of the bacterial ribosome at the tetracycline-binding site with an affinity similar to glycylcyclines. It is able to bypass older tetracycline resistance mechanisms and demonstrates activity against bacterial strains that are tetracycline resistant. In addition, omadacycline displays broad-spectrum activity against gram-positive organisms (including methicillin-resistant Staphylococcus aureus and vancomycin resistant enterococci), gram-negative organisms, atypical organisms, and anaerobes. It has been evaluated against infections in adults both intravenously and orally. Dosage adjustments are not required for patients with renal impairment. Omadacycline displays a comparable efficacy and safety profile to standard-of-care agents, with the most common side effects observed being gastrointestinal. Currently available data for omadacycline suggest that this is a promising agent added to our antimicrobial armamentarium. PMID- 30290001 TI - Unfolding the pleiotropic facades of rosuvastatin in therapeutic intervention of myriads of neurodegenerative disorders. AB - Rosuvastatin, a 3-hydroxy-3-methylglutaryl-coenzyme (HMG-CoA) reductase inhibitor, and one of the most popular antihyperlipidemic medications has been found to possess pharmacodynamic activities much different from its usual indication. Recent research studies have revealed the efficacy of rosuvastatin in attenuating neuroinflammation, reducing the progression of Alzheimer's disease, providing protection against cerebral ischemia and spinal cord injury as well as ameliorating epilepsy. Mechanisms behind the neuroprotective potential of rosuvastatin can be attributed to its pleiotropic effects, independent of its ability to inhibit HMG-CoA reductase. These processes include modulation of several cellular pathways, isoprenylation, effects on oxidative stress, nitrosative levels, inflammation, and immune response. With this review, we aim to assimilate and summarize recent findings on the pharmacological actions of rosuvastatin in attenuating neurological disorders in order to give way for future research in this space.

AB - The availability of novel biomarkers in several branches of medicine opens room for refining prognosis by adding factors on top of those having an established role. It is accepted that the impact of novel factors should not rely solely on regression coefficients and their significance but also on predictive power measures, such as Brier score and ROC-based quantities. However, novel factors that are promising at the exploratory stage often result in disappointingly low impact in the predictive power. This motivated the proposal of the net reclassification improvement and the integrated discrimination improvement, as direct measures of predictive power gain due to additional factors based on the concept of reclassification tables. These measures became extremely popular in cardiovascular disease and cancer applications, given the apparently easy interpretation. However, recent contributions in the biostatistical literature enlightened the tendency to indicate as advantageous models obtained by adding unrelated factors. These measures should not be used in practice. A further measure proposed a decade ago, the net benefit, is becoming a standard in assessing the consequences in terms of costs and benefits when using a risk predictor in practice for classification. This work reviews the conceptual formulations and interpretations of the available graphical methods and summary measures for evaluating risk predictor models. The aim is to provide guidance in the evaluation process that from the model development brings the risk predictor to be used in clinical practice for binary decision rules. PMID- 30290003 TI - Tyrosine kinase inhibitor interruptions, discontinuations and switching in patients with chronic-phase chronic myeloid leukemia in routine clinical practice: SIMPLICITY. AB - SIMPLICITY (NCT01244750) is an observational study exploring tyrosine kinase inhibitor (TKI) use and management patterns in patients with chronic phase chronic myeloid leukemia in the US and Europe in routine clinical practice. Herein we describe interruptions, discontinuations and switching of TKI therapy during the initial 2 years of treatment among 1121 patients prospectively enrolled between October 1, 2010 and March 7, 2017. Patient characteristics were broadly similar between the imatinib (n = 370), dasatinib (n = 376), and nilotinib (n = 375) cohorts. Treatment interruptions occurred in 16.4% (year 1) and 4.0% (year 2) of patients, mainly attributed to hematologic intolerances. Treatment discontinuations occurred in 21.8% (year 1) and 10.2% (year 2) of patients, with the highest rate within the first 3 months for intolerance. Switching of TKI was seen in 17.8% (year 1) and 9.5% (year 2) of patients. Significant associations were found between TKI switching and female gender (year 1), age >=65 years at diagnosis (year 2) and treatment with imatinib (year 2). Intolerance was the most common reason given for patients discontinuing and for switching TKI therapy; however resistance was also cited. Lack of response monitoring in routine clinical practice may have resulted in lower identification of resistance in this dataset. Data from SIMPLICITY suggest that, in routine clinical practice, intolerance and resistance to TKIs influence decisions to change treatment. Changes in TKI therapy are frequent, with nearly a third of patients discontinuing their first-line TKI. PMID- 30290004 TI - Point-of-care screening for sickle cell disease in low-resource settings: A multi center evaluation of HemoTypeSC, a novel rapid test. AB - Sickle cell disease (SCD) is a common, life-threatening genetic disorder that is best managed when diagnosed early by newborn screening. However, SCD is most prevalent in low-resource regions of the world where newborn screening is rare and diagnosis at the point-of-care is challenging. In many such regions, the majority of affected children die, undiagnosed, before the age of 5 years. A rapid and affordable point-of-care test for SCD is needed. The diagnostic accuracy of HemoTypeSC, a point-of-care immunoassay, for SCD was evaluated in individuals who had SCD, hemoglobin C disease, the related carrier (trait) states, or a normal hemoglobin phenotype. Children and adults participated in low , medium- and high-resource environments (Ghana [n = 383], Martinique [n = 46], and USA [n = 158]). Paired blood specimens were obtained for HemoTypeSC and a reference diagnostic assay. HemoTypeSC testing was performed at the site of blood collection, and the reference test was performed in a laboratory at each site. In 587 participants, across all study sites, HemoTypeSC had an overall sensitivity of 99.5% and specificity of 99.9% across all hemoglobin phenotypes. The test had 100% sensitivity and specificity for sickle cell anemia. Sensitivity and specificity for detection of normal and trait states were >99%. HemoTypeSC is an inexpensive (<$2 per test), accurate, and rapid point-of-care test that can be used in resource-limited regions with a high prevalence of SCD to provide timely diagnosis and support newborn screening programs. PMID- 30290005 TI - The journey of metformin from glycaemic control to mTOR inhibition and the suppression of tumour growth. AB - Our knowledge of the effect of metformin on human health is increasing. In addition to its ability to improve the control of hyperglycaemia, metformin has been shown to reduce the burden o,f ageing via effects on damaged DNA and the process of apoptosis. Studies have shown that metformin may reduce the risk of cardiovascular disease through influences on body weight, blood pressure, cholesterol levels and the progression of atherosclerosis. Studies also suggest that metformin may be beneficial for neuro-psychiatric disorders, cognitive impairment and in reducing the risk of dementia, erectile dysfunction and Duchenne muscular dystrophy. In vivo and in vitro studies have shown that metformin has anti-cancer properties, and population studies have suggested that metformin may reduce the risk of cancer or improve cancer prognosis. It is thought that it exerts its anti-cancer effect through the inhibition of the mammalian target of rapamycin (mTOR) signalling pathway. Because of its effect on the mTOR pathway, there may be a role for metformin in slowing or reversing growth of life-threatening hamartomas in tuberous sclerosis complex. PMID- 30290006 TI - Protective role of skeletal muscle mass against progression from metabolically healthy to unhealthy phenotype. AB - OBJECTIVE: Metabolically healthy individuals are known to be resistant to cardiovascular disease development. However, a considerable fraction of those individuals shows deteriorated metabolic health over time. Although skeletal muscle is the primary insulin-responsive target organ, a longitudinal investigation of the skeletal muscle mass in relation to the development of metabolically unhealthy phenotype has not been performed. We aimed to evaluate whether greater skeletal muscle mass is an independent protective factor for the development of metabolically unhealthy phenotype. DESIGN, PARTICIPANTS AND MEASUREMENTS: We conducted a retrospective cohort study with 9033 metabolically healthy volunteers who underwent routine health examinations in 2012 and a follow up examination in 2016. Obesity was defined as Asian-Pacific body mass index criterion >=25 kg/m2 . Subjects with fewer than two risk factors (elevated blood pressure, triglyceride, glucose, high-sensitivity C-reactive protein, insulin resistance and decreased high-density lipoprotein cholesterol levels) were characterized as metabolically healthy using Wildman criteria. RESULTS: At the 4 year follow-up, approximately one-fourth of the nonobese participants and half of the participants with obesity showed metabolic deterioration. In nonobese men and women, higher appendicular skeletal muscle mass (ASM)/weight at baseline was significantly associated with decreased risk of metabolic deterioration. Compared to the lowest quartile of ASM/weight, the adjusted odds ratios (95% confidence intervals) of the highest quartile were 0.68 (0.52-0.89) in nonobese men and 0.64 (0.46-0.90) in nonobese women. However, this association was not observed in obese subjects. CONCLUSIONS: Greater skeletal muscle mass at baseline is significantly associated with maintenance of metabolically healthy status, especially in nonobese individuals. PMID- 30290007 TI - A 5-year prospective study on the clinical and aesthetic outcomes of alveolar ridge preservation and connective tissue graft at the buccal aspect of single implants. AB - AIM: To evaluate the 5-year aesthetic outcome of single implants following alveolar ridge preservation (ARP) and connective tissue graft (CTG) at the buccal aspect. MATERIALS AND METHODS: Thirty-seven periodontally healthy non-smoking patients received flapless tooth extraction, ARP with a deproteinized bovine bone mineral with 10% collagen (DBBMC), implant placement (4-6 months later), a provisional screw-retained crown and CTG at the buccal mucosa (3 months later) and a permanent crown (3 months later). The aesthetic results were the primary outcome and the clinical results the secondary outcome of the study. Both outcomes were compared to those after 1 year. Mucosal thickness (MT) was registered using a non-invasive ultrasonic device. RESULTS: Thirty-two patients attended the 5-year re-assessment, and all implants survived. Mean marginal bone loss was 0.53 mm at 1 year and 0.47 mm at 5 years (p = 0.439). Mesial Papilla showed a further re-growth between 1 and 5 years (p = 0.043). Mid-facial recession amounted to 0.05 mm and 0.12 mm at 1 and 5 years, respectively (p = 0.161). The Pink Esthetic Score was 11.00 and 11.17 at 1 and 5 years, respectively (p = 0.596). MT gain amounted to 0.97 mm (relative stability: 90.5%) and 0.91 mm (relative stability: 85%) at 1 and 5 years, respectively (p = 0.249). CONCLUSION: ARP and CTG resulted in favourable clinical and aesthetic outcomes. CTG substantially increased MT with acceptable stability over a 5-year period. PMID- 30290008 TI - Donepezil-melatonin hybrids as butyrylcholinesterase inhibitors: Improving binding affinity through varying mode of linking fragments. AB - Hybrid inhibitors of acetyl- and butyrylcholinesterase are compounds that combine structural motifs of two different classical inhibitors, leading to a dual binding ligand. A rapidly growing collection of those compounds involves a wide diversity of structural motifs, but the way of linking two active fragments and its impact on the affinity toward cholinesterases usually remains beyond the extent of investigation. We present hereby a detailed analysis of this aspect using melatonin-donepezil hybrids. A new series of compounds, in which two fragments are connected using a carbamate linker, exhibits excellent activity and selectivity toward butyrylcholinesterase. PMID- 30290009 TI - Neighbor balance and evenness of distribution of treatment replications in row column designs. AB - Row-column designs allow error control in field experiments by blocking in two dimensions. While this strategy can capture spatial heterogeneity aligned with blocks and account for effects due to the farming operations along rows and columns, it suffers from the occasional clustered occurrence of several replications of the same treatment. This property of classical row-column designs has hampered their more widespread use in practice. A further issue of practical importance is the degree of neighbor balance of a design, that is, the frequency of adjacencies of pairs of treatments. This paper proposes two design strategies to simultaneously optimize the evenness of spatial distribution of treatment replication as well as neighbor balance. Three examples are given to illustrate the proposed methods and demonstrate that both approaches yield comparable and satisfactory results. PMID- 30290010 TI - Verticillium dahliae transcription factors Som1 and Vta3 control microsclerotia formation and sequential steps of plant root penetration and colonisation to induce disease. AB - Verticillium dahliae nuclear transcription factors Som1 and Vta3 can rescue adhesion in a FLO8-deficient Saccharomyces cerevisiae strain. Som1 and Vta3 induce the expression of the yeast FLO1 and FLO11 genes encoding adhesins. Som1 and Vta3 are sequentially required for root penetration and colonisation of the plant host by V. dahliae. The SOM1 and VTA3 genes were deleted and their functions in fungus-induced plant pathogenesis were studied using genetic, cell biology, proteomic and plant pathogenicity experiments. Som1 supports fungal adhesion and root penetration and is required earlier than Vta3 in the colonisation of plant root surfaces and tomato plant infection. Som1 controls septa positioning and the size of vacuoles, and subsequently hyphal development including aerial hyphae formation and normal hyphal branching. Som1 and Vta3 control conidiation, microsclerotia formation, and antagonise in oxidative stress responses. The molecular function of Som1 is conserved between the plant pathogen V. dahliae and the opportunistic human pathogen Aspergillus fumigatus. Som1 controls genes for initial steps of plant root penetration, adhesion, oxidative stress response and VTA3 expression to allow subsequent root colonisation. Both Som1 and Vta3 regulate developmental genetic networks required for conidiation, microsclerotia formation and pathogenicity of V. dahliae. PMID- 30290011 TI - Cis-trans controls and regulatory novelty accompanying allopolyploidization. AB - Allopolyploidy is a prevalent process in plants, having important physiological, ecological and evolutionary consequences. Transcriptomic responses to genomic merger and doubling have been demonstrated in many allopolyploid systems, encompassing a diversity of phenomena including homoeolog expression bias, genome dominance, expression-level dominance and revamping of co-expression networks. Notwithstanding the foregoing, there remains a need to develop a conceptual framework that will stimulate a deeper understanding of these diverse phenomena and their mechanistic interrelationships. Here we introduce considerations relevant to this framework with a focus on cis-trans interactions among duplicated genes and alleles in hybrids and allopolyploids. By extending classic allele-specific expression analysis to the allopolyploid level, we distinguish the distinct effects of progenitor regulatory interactions from the novel intergenomic interactions that arise from genome merger and allopolyploidization. This perspective informs experiments designed to reveal the molecular genetic basis of gene regulatory control, and will facilitate the disentangling of genetic from epigenetic and higher-order effects that impact gene expression. Finally, we suggest that the extended cis-trans model may help conceptually unify several presently disparate hallmarks of allopolyploid evolution, including genome-wide expression dominance and biased fractionation, and lead to a new level of understanding of phenotypic novelty accompanying polyploidy. PMID- 30290012 TI - Maternal L-carnitine supplementation ameliorates renal underdevelopment and epigenetic changes in male mice offspring due to maternal smoking. AB - OBJECTIVES: Epidemiological and animal studies showed that L-carnitine (LC) supplementation can ameliorate oxidative stress-induced tissues damage. We have previously shown that maternal cigarette smoke exposure (SE) can increase renal oxidative stress in newborn offspring with postnatal kidney underdevelopment and renal dysfunction in adulthood, which were normalised by LC administration in the SE dams during pregnancy. Exposure to an adverse intrauterine environment may lead to alteration in the epigenome, a mechanism by which adverse prenatal conditions increase the susceptibility to chronic disease later in life. The current study aimed to determine whether maternal SE induces epigenetic changes in the offspring's kidney are associated with renal underdevelopment, and the protective effect of maternal LC supplementation. METHOD: Female Balb/c mice (7 weeks) were exposed to cigarette smoke (SE) or air (Sham) for 6 weeks prior to mating, during gestation and lactation. A subgroup of the SE dams received LC via drinking water (SE + LC, 1.5 mmol/L) throughout gestation and lactation. Male offspring were studied at postnatal day (P)1, P20, and 13 weeks. RESULTS: Maternal SE altered the expression of renal development markers glial cell line derived neurotrophic factor and fibroblast growth factor 2, which were associated with increased renal global DNA methylation and DNA methyltransferase 1 mRNA expression at birth. These disorders were reversed by maternal LC administration. CONCLUSION: The effect of maternal SE on renal underdevelopment involves global epigenetic alterations from birth, which can be prevented by maternal LC supplementation. PMID- 30290013 TI - Incidence of cytomegalovirus in cardiac transplant recipients receiving induction immunosuppression with antithymocyte globulin. AB - BACKGROUND: Cytomegalovirus (CMV) is a major cause of morbidity and mortality in cardiac transplant recipients. Use of induction immunosuppression in cardiac transplantation may have an impact on the incidence of CMV, but literature is limited. METHODS: Single-center, retrospective cohort study comparing the risk of CMV infection and disease in cardiac transplant patients receiving antithymocyte globulin (ATG) induction therapy to those receiving no antibody induction. RESULTS: A total of 75 patients were included in our analysis, 50 who received ATG induction and 25 who did not. CMV infection occurred in 10 (20%) and 5 (20%) patients in the ATG and No ATG groups, respectively (P > 0.99). CMV disease occurred in 10 (20%) and 4 (16%) patients in the ATG and No ATG groups, respectively (P = 0.763). The median time from transplant to CMV infection was 200.0 [142.5, 364.5] days in the ATG group vs 221.0 [192.0, 299.0] days in the No ATG group (P = 0.723). The median time from end of CMV prophylaxis to CMV infection was 94.5 [66.5, 151.0] days in the ATG group vs 53.0 [41.0,149.5] days in the No ATG group (P = 0.202). Freedom from CMV infection was highest in the D+/R+ group and lowest in the D+/R- group. CONCLUSION: In cardiac transplant recipients, ATG induction was not associated with an increased incidence of CMV infection or disease in the setting of valganciclovir prophylaxis and an initial maintenance immunosuppression regimen of primarily steroids, mycophenolate mofetil, and tacrolimus. PMID- 30290014 TI - Leptin impairs the therapeutic effect of ionizing radiation in oral squamous cell carcinoma cells. AB - PURPOSE: Leptin, an important hormone controlling energy homeostasis, has been linked to the pathogenesis of oral squamous cell carcinoma (OSCC). Evidence indicates that head and neck cancer patients undergoing radiotherapy show decreased leptin levels after radiotherapy treatment. Thus, we investigated, through phenotypic and molecular analyses, whether leptin can compromise the therapeutic effect of ionizing radiation and neoplastic behavior of OSCC cells. METHODS: The human OSCC-derived cell lines SCC9 and SCC4 were treated with human recombinant leptin and exposed to 6 Gy of irradiation. We performed the in vitro assays of cell migration, death, proliferation, and colony-forming ability. The reactive oxygen species (ROS) levels and proteome analysis by mass spectrometry were also conducted. RESULTS: Leptin was able to increase cell proliferation, migration, and colony-forming ability, despite the suppressive effect induced by irradiation. Furthermore, the leptin promoted a significant reduction of ROS intracellular accumulation, and increased expression of the cancer-related proteins, as ACTC1, KRT6A, and EEF2 in irradiated OSCC cells. CONCLUSIONS: Our findings suggest that leptin impairs responsivity of OSCC cells to the ionizing radiation, reducing the suppressive effects of irradiation on the neoplastic phenotype, and increasing protein expression critical to carcinogenesis. PMID- 30290015 TI - Concurrent Infection of Batrachochytrium dendrobatidis and Ranavirus among Native Amphibians from Northeastern Oklahoma, USA. AB - Global amphibian decline continues to be a great concern despite our increased understanding of the causes behind the observed patterns of the decline, such as habitat modification and infectious diseases. Although there is a large body of literature on the topic of amphibian infectious diseases, pathogen prevalence and distribution among entire communities of species in many regions remain poorly understood. In addition to these geographic gaps in our understanding, past work has focused largely on individual pathogens, either Batrachochytrium dendrobatidis (Bd) or ranavirus (RV), rather than dual infection rates among host species. We sampled for prevalence and infection load of both pathogens in 514 amphibians across 16 total sites in northeastern Oklahoma. Amphibians were caught by hand, net, or seine; they were swabbed to screen for Bd; and liver tissue samples were collected to screen for RV. Overall results of quantitative PCR assays showed that 7% of screened individuals were infected with RV only, 37% were infected with Bd only, and 9% were infected with both pathogens simultaneously. We also documented disease presence in several rare amphibian species that are currently being monitored as species of concern due to their small population sizes in Oklahoma. This study synthesizes a growing body of research regarding infectious diseases among amphibian communities in the central United States. PMID- 30290016 TI - The value of dermoscopy in diagnosing eyebrow loss in patients with alopecia areata and frontal fibrosing alopecia. AB - INTRODUCTION: Alopecia areata and frontal fibrosing alopecia are common causes of eyebrow loss (madarosis). OBJECTIVE: Assessment of trichoscopic markers of eyebrow loss in alopecia areata and frontal fibrosing alopecia. MATERIALS AND METHODS: The analysis included 50 patients with scalp alopecia areata with madarosis, 50 patients with scalp frontal fibrosing alopecia with madarosis and 50 healthy controls. In every case, trichoscopy of the eyebrow area was performed. RESULTS: Empty follicular and eccrine duct openings were observed in all patients and presented predominantly as yellow dots. Exclamation mark hairs were only detected in patients with alopecia areata (30%). Tapered hairs, broken hair, black dots and Pohl-Pinkus constrictions were observed in 14%, 36%, 26% and 4% of patients with alopecia areata, respectively, 4%, 16%, 2% and 0% of patients with frontal fibrosing alopecia, respectively, and they were not present in healthy controls. Dystrophic hairs and whitish areas were observed only in patients with frontal fibrosing alopecia (28% and 32%, respectively). Eyebrow regrowth in distinct directions was present in 32% of patients with frontal fibrosing alopecia, 8% of patients with alopecia areata and 4% of healthy controls. Diffuse erythema was detected in 60% of patients with alopecia areata and frontal fibrosing alopecia and 56% of healthy controls. Vellus hairs and upright regrowing hairs were observed in patients with alopecia areata (62% and 58%, respectively), frontal fibrosing alopecia (60% and 84%, respectively) and healthy controls (100% and 100%, respectively). CONCLUSION: Trichoscopy of the eyebrow area is useful in diagnosing patients with isolated eyebrow loss. The most characteristic trichoscopic features of eyebrow loss in alopecia areata include exclamation mark hairs, tapered hairs, broken hairs and black dots. Frontal fibrosing alopecia of the eyebrows is characterized by the presence of dystrophic hairs, white areas and eyebrow regrowth in distinct directions. PMID- 30290017 TI - Role of synovium-derived fibrous cartilage in temporomandibular joint synovial chondromatosis. AB - BACKGROUND: Synovial chondromatosis (SC) of temporomandibular joint (TMJ) occupies 3% SC cases. In other joints like hip and knee which were composed hyaline cartilage (HC), loose bodies (LBs) were reported to be a HC feature. However, condyle surface and disc in TMJ are fibrous cartilage (FC). Therefore, we proposed a different pathogenesis of TMJSC. METHODS: LBs and synovium were collected from seven TMJSC patients, and histological and immunohistological examinations were performed. RESULTS: Three ways of HC formation were discovered: regular-shaped cartilaginous nodules (CNs) in sublining layer (SL) of vascularized synovium, regional chondrification of SL, and finger-like tissue with a tail attaching to synovium. Detached LBs could fuse and were only positively stained by aggrecan. Without synovium attachment to LBs, fused LBs remained a hyaline extracellular matrix (ECM). However, after synovium attachment, transformation from HC to FC occurred. Two types of FC were observed. First type FC was featured by vertical-distributed type I collagen fibers imbedding few chondrocytes, suggesting mature phase with superior mechanical features. Second type FC was featured by medium-density chondrocytes with type I collagen and aggrecan-positive ECM, suggesting primary phase. The transformation process started in appearance of 2nd type FC deriving from synovium covering LB, and gradually replaced HC from periphery to center. CONCLUSIONS: Three ways of HC formation were closely related. Different with SC in other joints, hyaline ECM in LBs of TMJSC could be replaced by FC deriving from synovium, during which 2nd type FC first replaced HC and then transformed to 1st type FC. PMID- 30290018 TI - Brimonidine displays anti-inflammatory properties in the skin through the modulation of the vascular barrier function. AB - BACKGROUND: Rosacea is a chronic inflammatory skin disease. Characteristic vascular changes in rosacea skin include enlarged, dilated vessels of the upper dermis and blood flow increase. Brimonidine is approved for symptomatic relief of the erythema of rosacea. It acts by selectively binding to alpha2-adrenergic receptors present on smooth muscle in the peripheral vasculature, resulting in transient local vasoconstriction. OBJECTIVES: To provide further evidence of the anti-inflammatory potential of brimonidine across preclinical models of skin inflammation and its ability to decrease the neutrophil infiltration in human skin after ultraviolet light exposure. METHODS: The anti-inflammatory properties of brimonidine through modulation of the vascular barrier function were assessed using in vivo neurogenic vasodilation and acute inflammatory models and a well described in vitro transmigration assay. A clinical study assessed the neutrophil infiltration in human skin after exposure to UV in 37 healthy Caucasian male subjects. RESULTS: In vitro, brimonidine affects the transmigration of human neutrophils through the endothelial barrier by modulating adhesion molecules. In vivo, in the mouse, topical treatment with brimonidine, used at a vasoconstrictive dose, confirmed its anti-inflammatory properties and prevented leucocyte recruitment (rolling and adhesion) mediated by endothelial cells. Topical pretreatment with brimonidine tartrate 0.33% gel once a day for 4 days significantly prevented neutrophil infiltration by 53.9% in human skin after exposure to UV light. CONCLUSION: Results from in vitro, in vivo and from a clinical study indicate that brimonidine impacts acute inflammation of the skin by interfering with neurogenic activation and/or recruitment of neutrophils. PMID- 30290019 TI - Declining in liver stiffness cannot indicate fibrosis regression in patients with chronic hepatitis B: A 78-week prospective study. AB - BACKGROUND AND AIM: Little reliable data are available about the liver stiffness measurement (LSM) for fibrosis monitoring in chronic hepatitis B (CHB) patients on antiviral therapy. We aimed to assess the accuracy of LSM in fibrosis monitoring during 78-week antiviral therapy in CHB patients. METHODS: Five hundred fifty-six treatment-naive CHB patients with qualified LSM and liver biopsy at baseline were analyzed. Patients receiving entecavir-based therapy were prospectively followed to 78 weeks for second LSM and liver biopsy. Serologic detection, LSM, and liver biopsy were performed on the same day. Necro inflammatory activity was also evaluated. RESULTS: Areas under receiver operating characteristics curves of LSM at baseline and week 78 for significant fibrosis (>= F3), advanced fibrosis (>= F4), and liver cirrhosis (>= F5) was 0.84, 0.87, 0.83 and 0.76, 0.85, 0.88, respectively. Patients with the same fibrosis stage but higher histology activity index score tend to have higher LSM at baseline. Liver stiffness decreased rapidly (3.8 [1.6-8.6] kPa) in parallel with baseline histology activity index scores from 11.3 (7.8-16.7) kPa at baseline to 6.4 (5.1 8.8) kPa at week 78. Greater decline of LSM in patients with only inflammation improvement was observed as compared with those without inflammation improvement (5.2 [2.5-9.7] vs 1.8 [0.2-8.1] kPa, P = 0.013). Baseline Ishak fibrosis score was the only predictor of 78-week fibrosis improvement (odds ratio, 1.859; P = 0.000). CONCLUSIONS: In CHB patients receiving 78-week antiviral treatment, LSM could diagnosis different liver fibrosis stages, decrease in absolute LSM value could reflect the remission of liver inflammation, and baseline Ishak fibrosis score was the only predictor for 78-week fibrosis reversion. PMID- 30290020 TI - Nilotinib induction of melanogenesis via reactive oxygen species-dependent JNK activation in B16F0 mouse melanoma cells. AB - Nilotinib (AMN), a second-generation tyrosine kinase inhibitor, induces apoptosis in various cancer cells, and our recent study showed that AMN effectively reduced the viability of human ovarian cancer cells via mitochondrion-dependent apoptosis. The effect of AMN in the melanogenesis of melanoma cells is still unclear. In the present study, we found that the addition of AMN but not imatinib (STI) significantly increased the darkness of B16F0 melanoma cells, and the absorptive value increased with the concentration of AMN. A decrease in the viability of B16F0 cells by AMN was detected in a concentration-dependent manner, accompanied by increased DNA ladders, hypodiploid cells and cleavage of the caspase-3 protein. An in vitro tyrosinase (TYR) activity assay showed that increased TYR activity by AMN was detected in a concentration-dependent manner; however, induction of TYR activity by STI at a concentration of 40 MUmol/L was observed. Increased intracellular peroxide by AMN was detected in B16F0 cells, and application of the antioxidant, N-acetylcysteine (NAC), significantly reduced AMN-induced peroxide production which also reduced the darkness of B16F0 cells. Additionally, AMN induced c-Jun N-terminal kinase (JNK) protein phosphorylation in B16F0 cells, which was inhibited by the addition of NAC. AMN-induced melanogenesis of B16F0 cells was significantly inhibited by the addition of NAC and the JNK inhibitor, SP600125 (SP). Data of Western blotting showed that increased protein levels of melanogenesis-related enzymes of tyrosinase-related protein-1 (TRP1), TRP2 and TYR were observed in AMN-treated B16F0 cells which were inhibited by the addition of NAC and SP. Evidence is provided supporting AMN effectively inducing the melanogenesis of B16F0 melanoma cells via reactive oxygen species-dependent JNK activation. PMID- 30290021 TI - Evidence-based clinical guidelines on analgesia and sedation in newborn infants undergoing assisted ventilation and endotracheal intubation. AB - AIM: This review informed pain control guidelines for clinicians performing mechanical ventilation, nasal continuous positive airway pressure and endotracheal intubation on term and preterm newborn infants. METHODS: We reviewed literature published between 1986 and June 2017 on analgesia and sedation during assisted ventilation and before endotracheal intubation in newborn infants admitted to neonatal intensive care units. The subsequent guidelines were developed using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: Our review produced five strong standard of care recommendations. One, reduce neonatal stress and use nonpharmacological analgesia during invasive ventilation. Two, favour intermittent boluses of opioids, administered after pain scores and before invasive procedures, during short expected periods of mechanical ventilation, mainly in preterm infants affected by respiratory distress syndrome. Three, do not use morphine infusion in preterm infants under 27 gestational weeks. Four, always use algometric scores to titrate analgesic drugs doses. Five, use premedication before endotracheal intubation for a more rapid, less painful, less traumatic and safer manoeuvre. We also developed 30 conditional recommendations on therapeutic options. CONCLUSION: Our review produced 35 recommendations on standard care and therapeutic options relating to the analgesia and sedation of newborn infants during ventilation and before endotracheal intubation. PMID- 30290022 TI - Toxicity of iron oxide nanoparticles: Size and coating effects. AB - Toxicological research of novel nanomaterials is a major developmental step of their clinical approval. Since iron oxide magnetic nanoparticles have a great potential in cancer treatment and diagnostics, the investigation of their toxic properties is very topical. In this paper we synthesized bovine serum albumin coated iron oxide nanoparticles with different sizes and their polyethylene glycol derivative. To prove high biocompatibility of obtained nanoparticles the number of in vitro toxicological tests on human fibroblasts and U251 glioblastoma cells was performed. It was shown that albumin nanoparticles' coating provides a stable and biocompatible shell and prevents cytotoxicity of magnetite core. On long exposure times (48 hours), cytotoxicity of iron oxide nanoparticles takes place due to free radical production, but this toxic effect may be neutralized by using polyethylene glycol modification. PMID- 30290023 TI - Low irradiance compared with conventional photodynamic therapy in the treatment of actinic keratoses. AB - BACKGROUND: Photodynamic therapy (PDT) is an effective therapy treating photodamaged areas with multiple actinic keratoses (AK). Still pain during therapy is one of the most challenging obstacles for patients. This retrospective study compares pain and efficacy intra-individual in patients using conventional PDT (c-PDT) compared to a low irradiance PDT protocol (li-PDT) with a reduced irradiance to 25% of c-PDT. METHODS: Thirty-one patients were enrolled into this retrospective analysis treated with li-PDT and c-PDT on comparable fields of actinic damage on the forehead or the cheek. Pain was scored by the patients using a VAS. Moreover, number and time to therapy interruptions were documented. For effectiveness number and grade of AK were counted before and 4 weeks after PDT. RESULTS: Maintaining a total light dose of 37 J/cm2 , a decrease in irradiation in li-PDT patients resulted in significant less pain (VAS score 2.8 vs 7.6) and fewer therapy interruptions compared to treatment with c- PDT (P < 0.0005). No significant difference in treatment outcome was found (P = 0.068). CONCLUSION: Our data shows that li-PDT can reduce pain with at least comparable clinical outcome compared to c-PDT. Therefore, it is an effective and well tolerated treatment for patients with multiple AK. PMID- 30290024 TI - From the Editors. PMID- 30290025 TI - Cardiac xenografts show reduced survival in the absence of transgenic human thrombomodulin expression in donor pigs. AB - A combination of genetic manipulations of donor organs and target-specific immunosuppression is instrumental in achieving long-term cardiac xenograft survival. Recently, results from our preclinical pig-to-baboon heterotopic cardiac xenotransplantation model suggest that a three-pronged approach is successful in extending xenograft survival: (a) alpha-1,3-galactosyl transferase (Gal) gene knockout in donor pigs (GTKO) to prevent Gal-specific antibody mediated rejection; (b) transgenic expression of human complement regulatory proteins (hCRP; hCD46) and human thromboregulatory protein thrombomodulin (hTBM) to avoid complement activation and coagulation dysregulation; and (c) effective induction and maintenance of immunomodulation, particularly through co stimulation blockade of CD40-CD40L pathways with anti-CD40 (2C10R4) monoclonal antibody (mAb). Using this combination of manipulations, we reported significant improvement in cardiac xenograft survival. In this study, we are reporting the survival of cardiac xenotransplantation recipients (n = 3) receiving xenografts from pigs without the expression of hTBM (GTKO.CD46). We observed that all grafts underwent rejection at an early time point (median 70 days) despite utilization of our previously reported successful immunosuppression regimen and effective control of non-Gal antibody response. These results support our hypothesis that transgenic expression of human thrombomodulin in donor pigs confers an independent protective effect for xenograft survival in the setting of a co stimulation blockade-based immunomodulatory regimen.

PMID- 30290026 TI - Synthesis, Structure and Nickel Carbonyl Complexes of Dialkylterphenyl Phosphines. AB - The experimental and computational characterization of a series of dialkylterphenyl phosphines, PR2 Ar' is described. The new P-donors comprise five compounds of general formula PR2 Ar Dtbp2 (R=Me, Et, iPr, c-C5 H9 and c-C6 H11 ); Ar Dtbp2 = 2,6-C6 H3 -(3,5-C6 H3 -(CMe3 )2 )2 ), and another five PR2 Ar' phosphines containing the bulky alkyl groups iPr, c-C5 H9 or c-C6 H11 , in combination with Ar'=Ar Xyl2 , Ar Xyl'2 , or Ar Ph2 (L1-L10). Steric and electronic parameters have been determined computationally and from IR and X-ray data obtained for the phosphines and for some derivatives, including tricarbonyl and dicarbonyl nickel complexes, Ni(CO)3 (PR2 Ar') and Ni(CO)2 (PR2 Ar'). In the solid state, the free phosphines PR2 Ar' adopt one of the three possible structures formally related by rotation around the Cipso -P bond. Details on their relative energies and on the influence of the free phosphine structure on its coordination chemistry towards Ni(CO)n (n = 2, 3) fragments has been obtained by experimental and computational methods. PMID- 30290028 TI - INSM1 expression in pancreatic neuroendocrine tumors in endoscopic ultrasound guided fine needle aspiration cytology: an analysis of 14 patients. AB - BACKGROUND: Insulinoma-associated protein 1 (INSM1) has been reported to be a useful marker for diagnosing pancreatic neuroendocrine tumors (PNETs). However, INSM1 expression in endoscopic ultrasound-fine needle aspiration cytology (EUS FNAC) has not been examined. We evaluated INSM1 expression in the cytology of cases diagnosed with PNETs. METHODS: We immunocytochemically stained INSM1 and Ki 67 in 14 PNET cases, and according to the 2017 World Health Organization criteria, 7 PNET Grade 1 (G1) cases, 4 Grade 2 (G2) cases, and 3 Grade 3 (G3)/neuroendocrine carcinoma (NEC) cases were identified. As a control for INSM1 and Ki-67 expression, we used cytological specimens from 15 cases of pancreatic ductal adenocarcinoma (PDAC). RESULTS: In PNET cases, INSM1-expressing tumor cells were identified in all cytological specimens of PNET. The median INSM1 expression rate in G1 cases was 49.8% (mean+/-SD: 55.1+/-12.5%, min: 39.3%, max: 74.1%), and in G2 and G3/NEC cases was 81.1% (mean+/-SD: 77.6+/-18.6%, min: 50.3%, max: 100%). However, there was no correlation between INSM1 and Ki-67 expression (r= -0.15).The median expression rate in PNET cases was 64.3%, which was significantly higher than that in PDAC cases (p<0.0001). CONCLUSION: INSM1 immunocytochemistry of cytological specimens obtained from EUS-FNAC can accurately diagnose PNETs; therefore, INSM1 could be an important diagnostic tool in assessing therapeutic strategies, including molecular-targeted therapy.

AB - Depending on a person's goals, different aspects of stored knowledge are accessed. Decades of behavioral work document the flexible use of knowledge, but little neuroimaging work speaks to these questions. We used representational similarity analysis to investigate whether the relationship between brain activity and semantic structure of statements varied in two tasks hypothesized to differ in the degree to which knowledge is accessed: judging truth (semantic task) and judging oldness (episodic task). During truth judgments, but not old/new recognition judgments, a left-lateralized network previously associated with semantic memory exhibited correlations with semantic structure. At a neural level, people activate knowledge representations in different ways when focused on different goals. The present results demonstrate the potential of multivariate approaches in characterizing knowledge storage and retrieval, as well as the ways that it shapes our understanding and long-term memory. PMID- 30290030 TI - Microvesicles Secreted by Nitric Oxide-Primed Mesenchymal Stromal Cells Boost the Engraftment Potential of Hematopoietic Stem Cells. AB - Patients with leukemia, lymphoma, severe aplastic anemia, etc. are frequently the targets of bone marrow transplantation, the success of which critically depends on efficient engraftment by transplanted hematopoietic cells (HSCs). Ex vivo manipulation of HSCs to improve their engraftment ability becomes necessary when the number or quality of donor HSCs is a limiting factor. Due to their hematopoiesis-supportive ability, bone marrow-derived mesenchymal stromal cells (MSCs) have been traditionally used as feeder layers for ex vivo expansion of HSCs. MSCs form a special HSC-niche in vivo, implying that signaling mechanisms operative in them would affect HSC fate. We have recently demonstrated that AKT signaling prevailing in the MSCs affect the HSC functionality. Here we show that MSCs primed with nitric oxide donor, Sodium nitroprusside (SNP), significantly boost the engraftment potential of the HSCs co-cultured with them via intercellular transfer of microvesicles (MVs) harboring mRNAs encoding HSC supportive genes. Our data suggest that these MVs could be used as HSC-priming agents to improve transplantation efficacy. Since both, nitric oxide donors and MSCs are already in clinical use; their application in clinical settings may be relatively straight forward. This approach could also be applied in regenerative medicine protocols. Stem Cells 2018. PMID- 30290031 TI - Rethinking the evolution of property and possession: A review and methodological proposition. AB - Property is a key feature of modern human society; however, identifying the origin of this multifaceted behavior poses a formidable challenge. Here, we explore the methodologies for researching the origin of property. We discuss how an interdisciplinary approach can shed light on how our human ancestors shifted behaviorally from possessing an object to having exclusive property control over it. Possession occurs when social group members only respect an individual's claim to have exclusive access to an object when the individual has physical control over the object. Property occurs when an individual can claim exclusive access to an object, without challenge, regardless of whether the object is in their physical control or not. Researchers across different disciplines have asked what, if anything, distinguishes human property behavior from the behavior of other animals? Further, when and how did this behavior evolve in our lineage? Due to the considerable methodological challenges posed by researching this topic, few studies have been able to directly address these questions. In this review, we explore the challenges involved in defining property and possession and suggest a two-step approach to interdisciplinary definitions. Next, we evaluate four core approaches to the study of property behavior: evolutionary game theory, ethology, comparative cognition, and developmental psychology. Finally, we propose an empirical study, using an ethological approach to test the presence of property and possessive behavior in a natural setting, using our closest living relative, the chimpanzee (Pan troglodytes). Overall, we argue that this field of research is at a turning point, where the novel integration of various methods may provide an explanation to the origin of property. PMID- 30290032 TI - Family characteristics and children's knowledge on cardiovascular risk factors. AB - BACKGROUND: Cardiovascular disease has the highest mortality rates than any other disease globally. Some major risk factors seem to be established in early stages of life suggesting preventive strategies as a major mean to reduce cardiovascular mortality. The aim of the present work was to investigate the role of socioeconomic status and family characteristics on children's knowledge and perceptions concerning cardiovascular disease risk factors. METHODS: A cross sectional survey was conducted among 1728 children (46% male) aged 10 to 12 years, attending Greek primary schools in Athens, Heraklion (the capital City of the Island of Crete), Kalamata, Pyrgos and Sparti (Peloponnese peninsula), Greece. Sampling was conducted on school premises, during the school-years 2014 15 and 2015-16 (participation rate: 95-100%). Data were collected through a self administered, anonymous questionnaire. Children's knowledge concerning various issues related to cardiovascular risk, such as nutrition, physical activity and smoking was also examined. Data concerning family characteristics were collected through another questionnaire completed by parents. RESULTS: Paternal educational level and living with both parents instead of single-parent upbringing, were positively associated with children's knowledge regarding cardiovascular risk factors (b=0.42 (95%CI 0.01, 0.83), p=0.04 and b=0.78 (95%CI 0.013, 1.43), p=0.02 respectively). Moreover, children with more siblings seemed to have less sufficient knowledge compared to their peers who had fewer siblings (b per 1 sibling =-0.24 (95%CI -0.47, -0.014), p=0.04). CONCLUSIONS: The aforementioned findings enhance the link between the micro-environment and children's knowledge and perceptions concerning cardiovascular health, providing information to health care professionals while counseling youths.

PMID- 30290034 TI - Clinicopathological features of immunoglobulin G4-related pleural lesions and diagnostic utility of pleural effusion cytology. AB - OBJECTIVE: Immunoglobulin (Ig)G4-related disease is a recently described systemic immune-mediated fibro-inflammatory disease that frequently occurs in tumorous form. Herein, we elucidated the clinicopathological and cytological characteristics of IgG4-related pleural lesions (PLs). PATIENTS AND METHODS: Among 22 patients with fibro-inflammatory PLs of idiopathic aetiology, eight cases were diagnosed as IgG4-PL and the remaining 14 as non-IgG4-PL according to comprehensive diagnostic criteria for IgG4-related disease. Cell block examination of pleural effusion (CBPE) was performed in five patients with IgG4 PL and in six with non-IgG4-PL. Both groups were compared in terms of clinical presentation, laboratory data, histopathological features of resected pleura, and cytological features of pleural effusion (PE). RESULTS: PE was the most common (six patients, 75%) clinical presentation of IgG4-PL. IgG4-PL comparatively showed significantly more frequent concomitant allergic disease (P = .021), higher serum IgE levels (P = .012), higher adenosine deaminase levels in pleural fluid (P = .005), and rare spontaneous recovery without treatment (P = .046). The IgG4-PL group was histologically characterised by thicker fibrous pleura, storiform fibrosis, and infiltration of regulatory T cells, eosinophils and basophils. Using CBPE, IgG4-PL was cytologically distinct with numerous IgG4+ cells and eosinophils. The cytology of CBPE positively correlated with the histology of pleural tissue in the number of IgG4+ cells and eosinophils (R = .769 and .803, respectively). CONCLUSION: IgG4-PL frequently presents with PE and is histologically and cytologically characterised by abundant infiltration of IgG4+ cells and eosinophils. We believe that CBPE with immunohistochemistry/special staining could assist in the auxiliary diagnosis of IgG4-PL. PMID- 30290033 TI - Urea transport B gene induces melanoma B16 cell death via activation of p53 and mitochondrial apoptosis. AB - Urea Transporter B (UT-B) is a membrane channel protein that mediates the rapid transmembrane transport of urea and participates in urine concentration. Urea Transporter B is expressed in skin, but we found that there is little expression in human melanoma tissue. In this study, we examined the effects of UT-B overexpression in melanoma. The results indicated that there is no UT-B mRNA expression in B16 cells, and UT-B overexpression repressed B16 cell proliferation and induced apoptosis in vitro. We show that UT-B overexpression causes increased reactive oxygen species production, which may be caused by mitochondria dysfunction. The mitochondrial membrane potential (PsiDeltam) was lower in UT-B overexpressing B16 cells. The proteins involved in complexes I, III, IV and V of the respiratory chain were clearly downregulated in UT-B-overexpressing B16 cells, which would strongly reduce the activity of the electron transport chain. We found that mitochondrial release of cytochrome C into the cytoplasm also increased, indicating that apoptosis had been activated. In addition, UT-B overexpression reduced AKT phosphorylation and MDM2 expression and increased p53 expression; p53 activation may be involved in the anticancer effects of UT-B overexpression. Urea Transporter B overexpression also inhibited tumor growth in vivo. In conclusion, we demonstrated that UT-B may be related to the occurrence of melanoma and play a role in tumor development. PMID- 30290035 TI - Team-based parent training by child specialists helps maltreated children. AB - BACKGROUND: This study assessed the effects of the Parent Training (PT) technique, in which child specialists (CSs) such as preschool- and school teachers promote secure attachment in children with aberrant social behavior following maltreatment, using a team approach. METHODS: CSs confirmed the presence of child abuse, according to Japanese Ministry of Health, Labour and Welfare criteria. CSs such as homeroom, special education-related, student guidance-related, nursing teachers and co-workers received a PT course conducted by the authors. A homeroom teacher provided classroom management to model good examples of social life for the target child. A nursing teacher and assistant offered individualized instruction to foster the formation of secure attachments by the target child. RESULT: Behavioral abnormalities in both school and home resolved in 7 out of 12 cases. These cases received the intervention for 2 to 4 years. In the other cases, behavioral abnormalities disappeared or decreased in school, but continued at home. Almost all children met the alternative criteria of attachment disorder proposed by Borris and Zeanah. One child met the criteria for reactive attachment disorder (DSM-IV). This intervention is significantly more effective for children who have yet to begin elementary school than those in elementary school. CONCLUSIONS: This study indicates that the PT technique as applied by CSs using a team approach may be a useful intervention for fostering secure attachment in children with maltreatment who exhibit behavioral abnormalities. Early detection and intervention are necessary successfully to address the behavioral abnormalities of children with maltreatment. This article is protected by copyright. All rights reserved. PMID- 30290036 TI - A Systematic Study of Selective Protein Glycation. AB - Glycation is a non-enzymatic post-translational modification (PTM) that remains poorly understood, largely because it is unknown how it occurs selectively. Using mass spectrometry, it was possible to evaluate total glycation levels, identify distinct glycated products, assign unique glycation sites, and correlate these data with chemical and structural features for a panel of proteins glycated in vitro. It was determined that the extent of glycation does not correlate with pKa or surface exposure at reactive sites. Rather, the data reveal that primary sequence dictates the overall likelihood that a site will become glycated, while surrounding structure further sculpts the glycation outcome. Clustered acidic residues were found to prevent glycation, whereas a combination of tyrosine and polar residues appear to promote glycation. This work contributes important new knowledge about the molecular features that govern selective glycation. PMID- 30290037 TI - Testing the role of the posterior cingulate cortex in processing salient stimuli in cannabis users: an rTMS study. AB - The posterior cingulate cortex (PCC) and precuneus are hubs in the default mode network and play a role in processing external salient stimuli. Accordingly, activation in these regions has been associated with response to salient stimuli using drug cue-reactivity paradigms in substance using populations. These studies suggest that the PCC and precuneus may underlie deficits in processing salient stimuli that contribute toward the development of substance use disorders. The goal of this study was to directly test this hypothesis using repetitive transcranial magnetic stimulation (rTMS). Using a double-blind, placebo controlled design, we used rTMS to target the PCC and precuneus with a double cone coil at 10 Hz (high frequency) and 1 Hz (low frequency) in 10 adult cannabis users and 10 age- and sex-matched non-using controls. Electroencephalography data were collected before and after rTMS during a modified oddball paradigm with neutral, oddball, self-relevant, and cannabis-related stimuli. Cannabis users exhibited increased amplitude in P3 and faster latencies in the P3, N2, and P2 components in response to self-relevant stimuli compared to controls during baseline that normalized after rTMS. These results suggest that cannabis users exhibited heightened salience to external self-relevant stimuli that were modulated after rTMS. PCC dysfunction in cannabis users may be related to abnormalities in processing salient stimuli, such those during cue-reactivity, and provides a potential target for cannabis use disorder intervention. PMID- 30290039 TI - Double quantum filtered 23 Na MRI with magic angle excitation of human skeletal muscle in the presence of B0 and B1 inhomogeneities. AB - Double quantum filtered 23 Na MRI with magic angle excitation (DQF-MA) can be used to selectively detect sodium ions located within anisotropic structures such as muscle fibers. It might therefore be a promising tool to analyze the microscopic environment of sodium ions, for example in the context of osmotically neutral sodium retention. However, DQF-MA imaging is challenging due to various signal dependences, on both measurement parameters and external influences. The aim of this work was to examine how B0 in combination with B1 inhomogeneities alter the DQF-MA signal intensity. We showed that, in the presence of B0 inhomogeneities, flip angle schemes with only one 54.7 degrees pulse can be favorable compared with the classical 90 degrees -54.7 degrees -54.7 degrees scheme. DQF-MA images of the human lower leg were acquired at B0 = 3 T with a nominal spatial resolution of 12 * 12 * 36 mm3 within an acquisition time of TAcq < 10 min, and compared with spin density weighted (DW), as well as triple quantum filtration (TQF) 23 Na images. We found mean normalized signal-to-noise ratios of TQF/DW = 13.7 +/- 2.3% (tibialis anterior), 11.9 +/- 2.3% (soleus) and 11.4 +/- 2.2% (gastrocnemius medialis), as well as DQF-MA/DW = 4.7 +/- 1.1% (tibialis anterior), 3.3 +/- 0.73% (soleus) and 3.4 +/- 0.6% (gastrocnemius medialis). These ratios might serve as additional measures in future clinical studies of sodium retention within human skeletal muscle. However, the influence of B0 and B1 inhomogeneities should be considered when interpreting DQF-MA images.

PMID- 30290038 TI - A group of long noncoding RNAs identified by data mining can predict the prognosis of lung adenocarcinoma. AB - Long noncoding RNAs (lncRNA) are reported to be potential cancer biomarkers. This study aims to find new lncRNA biomarker relevant to lung adenocarcinoma. Gene expression profile and clinical data of lung adenocarcinoma and lung squamous cell carcinoma patients were downloaded from the UCSC Xena database. These data were analyzed to identify potential lncRNA prognostic biomarkers, and the candidate lncRNAs were analyzed and verified with association analysis, meta analysis, survival analysis, gene ontology analysis, gene set enrichment analysis, and other statistical methods. A group of 5 lncRNAs was identified from the 1965 differentially expressed (fold-change >2) genes. Four of these 5 lncRNAs were expressed at a lower level in lung adenocarcinoma tissues and the other one at a higher level (P < .0001). A risk score model was constructed using a linear combination of the expression levels of these lncRNAs. High-risk patients showed poorer overall survival (hazard ratio [HR] = 2.14; 95% confidence interval [CI], 1.67-3.06, P < .0001), disease-free survival (HR = 1.84; 95% CI, 1.26-2.35, P = .0007), and recurrence-free survival (HR = 1.51; 95% CI, 1.02-2.40, P = .04). The 5-fold cross-validation and subsequent meta-analysis further verified that patients in the low-risk group had better survival (95% CI, 0.74-1.79, Z = 4.72, P < .00001). Furthermore, both univariate and multivariate Cox regression analyses revealed that the prognostic value of these 5 lncRNAs was independent of other clinical prognostic factors. Further analysis indicated that these 5 lncRNAs might be associated with tumor metastasis. Taken together, our study suggests new prognostic lncRNA biomarkers for lung adenocarcinoma. PMID- 30290041 TI - Lymphadenitis by Non-tuberculous Mycobacteria in children. AB - BACKGROUND: Non-tuberculous Mycobacteria (NTM) constitute an important cause of cervical lymphadenitis in immunocompetent children. In this study we aimed at estimating the incidence of lymphadenitis due to NTM in children in Cyprus and describe the characteristics, diagnostic approaches, management and outcomes of such infections. METHODS: Children between the ages 1 to 5 years old, evaluated at our hospital from January 1st 2007 to December 31st 2016 for lymphadenopathy were included in the study. All children had a positive culture of a lymph node specimen for non-tuberculous Mycobacteria. RESULTS: A total of 22 cases of culture-positive lymphadenitis caused by NTM were reviewed. The patients' age ranged from 16 to 55 months. The tuberculin skin test revealed an induration in 81.0% of cases (diameter ranging from 4 - 17mm). M. avium was isolated in seventeen cases (77.3%), M. intracellulare in three (13.6%), M. paraffinicum in one (4.5%) and M. Kasansii in one case (4.5%). All 22 patients underwent surgical excision of affected nodes. Additional anti-mycobacterial treatment was given when complete excision was not achieved or for post-surgical recurrence. Complications were few and included scars in 3 children and a case of transient facial nerve palsy. CONCLUSION: Surgical excision of the infected lymph nodes by NTM is an effective diagnostic and therapeutic approach. In cases when total surgical excision is not feasible, a combination of partial excision with a clarithromycin including drug regimen appears safe, effective and causes milder and fewer complications as a result of surgery.

PMID- 30290043 TI - Role of Noxa in proliferation, apoptosis, and autophagy in human adenoid cystic carcinoma. AB - BACKGROUND: Noxa, which is subset of the Bcl-2 family of proteins, was previously reported to have considerable therapeutic potential in diverse cancers. However, its expression and role in salivary gland adenoid cystic carcinoma (ACC) have not been well studied. This study aimed to elucidate the expression and role of Noxa in salivary gland ACC. MATERIALS AND METHODS: The expression levels of NOXA and its association with overall survival in salivary gland ACC were analyzed by quantitative real-time PCR. We next examined the effects of Noxa overexpression or inhibition on colony formation, proliferation, apoptosis, and autophagy of salivary gland ACC cells. Furthermore, promoter analysis was performed to identify the potential transcriptional activator of NOXA. RESULTS: NOXA was markedly down-regulated and significantly correlated with a more aggressive phenotype and poor overall survival of salivary gland ACC. Ectopic expression of Noxa suppressed the viability and growth of ACC cells, which involved the induction of apoptosis and autophagy. Moreover, the transcriptional activity of NOXA gene could be enhanced by p53. CONCLUSION: The findings of this study indicate that Noxa, activated transcriptionally by p53, suppress the progression of ACC, whereby it regulates proliferation, apoptosis, and autophagy.

AB - The selective chloromethylenation of functionalized esters using chloroacetic acid (CA) and LiHMDS (HMDS=hexamethyldisilazide) in a continuous-flow setup is reported. This Claisen homologation is for the first time extended to bis chloromethylenation using dichloroacetic acid (DCA), thus giving access to under explored alpha,alpha'-bis-chloroketones. The use of flow conditions enables efficient generation and reaction of the unstable chloroacetate dianion intermediates, leading to unprecedented mild and scalable reaction conditions at an economical reagent stoichiometry (-10 degrees C, <1 min, 1.0-2.4 equiv dianion). The clean reaction profiles allow subsequent use of the unpurified crude products, which is demonstrated in the synthesis of various heterocycles of broad interest. Furthermore, we report a novel, catalyst-free substitution of the obtained monochloro ketone products with (hetero)aryl zinc enolates to give valuable 1,4-diketones.

Herein, we introduce the concept of kernel homology to describe the phenomenon of metal nanoclusters sharing the same "functional group" in kernels with some similar properties. To illustrate this point, we synthesized two novel gold nanoclusters, Au44 (TBBT)26 and Au48 (TBBT)28 (TBBTH=4-tert butylbenzenethiol), and solved their total structures by X-ray crystallography, which reveals that they have the same Au23 bi-icosahedron capped with a similar bottom cap (Au6 and Au8 , respectively) in the kernels. The two novel gold nanoclusters, together with the existing Au38 (PET)24 nanocluster (PETH=phenylethanethiol), have the same "functional group"-Au23 -in their kernels and have some similar properties (e.g., electrochemical properties); therefore, they are comparable to the homologues in organic chemistry.

AB - Biomacromolecular nanotubes play important physiological roles in transmembrane ion/molecule channeling, intracellular transport and inter-cellular communications. While genetically encoded protein nanotubes are predominant in vivo, the in vitro construction of biomimetic DNA nanotubes has attracted intense interest with the rise of structural DNA nanotechnology. The abiotic use of DNA assembly provides a powerful bottom-up approach for the rational construction of complex materials with arbitrary size and shape at the nanoscale. More specifically, a typical DNA nanotube can be assembled either with parallel aligned DNA duplexes or by closing DNA tile lattices. These artificial DNA nanotubes can be tailored and site-specifically modified to realize biomimetic functions including ionic or molecular channeling, bioreactors, drug delivery and biomolecular sensing. In this Minireview, we aim to summarize recent advances in design strategies, including the characterization and applications of biomimetic DNA nanotubes. PMID- 30290047 TI - Risk factors and epidemiology of pediatric ventriculoperitoneal shunt infections. AB - AIM: To identify independent risk factors for cerebrospinal fluid (CSF) shunt infection. METHODS: The medial records of all patients aged 0-18 years that underwent shunt-related surgeries for the treatment of hydrocephalus at our institution between January 1996 and December 2015 were reviewed. For each case, 2 randomly selected controls with no shunt infection were chosen. Demographic clinical and microbiological data were abstracted. RESULTS: A total of 1570 shunt related procedures met the inclusion criteria, yielding 68 infections (in 63 patients). The control group included 132 infection-free patients. The average annual infection rate was 4.2% cases per year. The median time between shunt procedures to infection was 19 days (range 1-2181). In multivariate analysis, risk factors associated with increased risk to develop an infection included: children who had two or more previous revisions in (odds ratio (OR) 4.8; 95%confidence interval (CI) 1.5-15.9), age of less than 5 years (OR 4.5; 95%CI 1.5-13.4). A neoplastic etiology for hydrocephalus was found to be a protective factor (p = 0.001) for shunt infection. CONCLUSIONS: A history of shunt revision was the most significant risk factor in the development of subsequent shunt infection. Age above 5 years was found to be a protective factor. Future efforts should focus on modalities to optimize revision procedures and reduce risks of subsequent infection This article is protected by copyright. All rights reserved.

AB - The incorporation of synthetic molecules as corner units in DNA structures has been of interest over the last two decades. In this work, we present a facile method for generating branched small molecule-DNA hybrids with controllable valency, different sequences, and directionalities (5'-3') using a "printing" process from a simple 3-way junction structure. We also show that the DNA imprinted small molecule can be extended asymmetrically using polymerase chain reaction (PCR) and can be replicated chemically. This strategy provides opportunities to achieve new structural motifs in DNA nanotechnology and introduce new functionalities to DNA nanostructures. PMID- 30290050 TI - Deaminative Borylation of Aliphatic Amines Enabled by Visible Light Excitation of an Electron Donor-Acceptor Complex. AB - A deaminative strategy for the borylation of aliphatic primary amines is described. Alkyl radicals derived from the single-electron reduction of redox active pyridinium salts, which can be isolated or generated in situ, were borylated in a visible light-mediated reaction with bis(catecholato)diboron. No catalyst or further additives were required. The key electron donor-acceptor complex was characterized in detail by both experimental and computational investigations. The synthetic potential of this mild protocol was demonstrated through the late-stage functionalization of natural products and drug molecules. PMID- 30290049 TI - Forkhead box C1 boosts triple-negative breast cancer metastasis through activating the transcription of chemokine receptor-4. AB - The transcription factor forkhead box C1 (FOXC1) has recently been proposed as a crucial regulator of triple-negative breast cancer (TNBC) and associated with TNBC metastasis. However, the mechanism of FOXC1 in TNBC development and metastasis is elusive. In this study, overexpression of FOXC1 in MDA-MB-231 cells significantly enhanced, whereas knockdown of FOXC1 in BT549 cells significantly reduced, the capabilities of TNBC cell invasion and motility in vitro and metastasis to the lung in vivo, when compared to their respective control cells. Mechanistic studies revealed that FOXC1 increased the expression of CXC chemokine receptor-4 (CXCR4), probably through transcriptional activation. AMD3100, an inhibitor of CXCR4, could block cell migration. In a zebrafish tumor model, AMD3100 could suppress cell invasion and metastasis. In addition, overexpressing CXCR4 in FOXC1-knockdown BT549 cells increased the capabilities of TNBC cell invasion and motility. In contrast, inhibition of CXCR4 with either AMD3100 or siRNA in MDA-MB-231 cells overexpressing FOXC1 reduced the capabilities of invasion and motility. Taken together, our results reveal a potential mechanism for FOXC1-induced TNBC metastasis.

AB - In this communication, the enantioselective synthesis of phthalides and isochromanones is described through a new palladium-catalyzed Heck-Matsuda arylation/NaBH4 -reduction/lactonization sequence of 2,3- and 2,5-dihydrofurans in good overall yields and excellent enantioselectivities (up to 98:2 er). This expeditious synthesis of chiral Heck lactol intermediates allowed the diversification of the strategy to obtain medicinally relevant chiral lactones, amines, and olefins. The natural product 3-butylphthalide was obtained in three steps with an overall yield of 33 % yield in 98:2 er. PMID- 30290052 TI - Effectiveness of Primary Care Interventions Using a Biopsychosocial Approach in Chronic Low Back Pain: A Systematic Review. AB - BACKGROUND AND OBJECTIVE: Recent systematic reviews show promising effects for multidisciplinary biopsychosocial (BPS) interventions in patients with chronic low back pain (CLBP). Nowadays, BPS interventions have also been developed for primary care physiotherapy settings. Our aim was to systematically review the evidence on the effectiveness of primary care BPS interventions in improving functional disability, pain, and work status for patients with CLBP. Secondly, we aimed to provide an elaborated overview of BPS intervention designs, physiotherapist training programs, and process-related factors (practical implementation). METHODS: We searched in scientific databases and reference lists. Randomized controlled trials (RCTs) evaluating primary care physiotherapist-led BPS interventions in adults (>=18 years) with nonspecific CLBP (>=12 weeks) were included. RESULTS: Our search resulted in 943 references; 7 RCTs were included (1,426 participants). Results show moderate-quality evidence (3 trials; 991 participants) that a BPS intervention is more effective than education/advice for reducing disability and pain in the short, medium, and long term. Low-quality evidence (4 trials; 435 participants) was found for no difference with physical activity treatments. CONCLUSIONS: BPS interventions seem more effective than education/advice and were found to be as effective as physical activity interventions in patients with CLBP. BPS interventions with a clear focus on psychosocial factors (understanding pain, unhelpful thoughts, coping styles, and goal setting) seem most promising. Sufficient delivery of BPS elements is expected when physiotherapists participate in training programs with extensive support prior and during delivery (manual, supervision, and informative resources). PMID- 30290053 TI - Sequences of Sequences: Spatial Organization of Coded Matter through Layer-by Layer Assembly of Digital Polymers. AB - A library of 16 digitally encoded polyanions was used in a layer-by-layer (LbL) polyelectrolyte assembly to nanofabricate thin films containing digitally coded strata. The polyanions were digital polyphosphodiesters (d-PPDE) prepared via an automated phosphoramidite process. Each component of the library contained 10 bytes of ASCII-encoded text (i.e. 80 coded monomers); thus the entire library allows the writing of a full sentence, which can be stored in a multilayer film as a sequence of sequences. To prepare fully segregated digital domains, non coded layers composed of poly(allylamine hydrochloride) (PAH)/poly(sodium 4 styrenesulfonate) (PSS) were included between the d-PPDE coded layers as an intermediate barrier. Detailed analysis of the film homogeneity indicated formation of 70 nm-thick films in which digital layers are kept apart from another by non-coded interlayers. As a result, the sequence-coded polymer library could be piled-up in a defined sequence of layers. PMID- 30290055 TI - Overview of sample introduction techniques prior to GC for the analysis of volatiles in solid materials. AB - Sample preparation and introduction techniques are very critical steps in gas chromatography analysis and particularly in the analysis of volatiles in solid samples. In these cases, they can be divided into two main categories: direct and indirect approaches, based on how the solid sample is treated, i.e. with and without dissolution (or extraction) of analytes from the solid sample. To enable routine application, coupling with sample preparation techniques (especially solid or solvent-based microextractions) is needed to achieve automation. Here, an overview of the most common sample introduction techniques for gas chromatography with their advantages and drawbacks is presented and discussed, including references to relevant examples. So, this review can serve as guidance for new users. PMID- 30290054 TI - Possible role of p53/Mieap-regulated mitochondrial quality control as a tumor suppressor in human breast cancer. AB - Mitochondria-eating protein (Mieap), encoded by a p53-target gene, plays an important role in mitochondrial quality control (MQC). Mieap has been reported to have a critical role in tumor suppression in colorectal cancer. Here, we investigated its role as a tumor suppressor in breast cancer. The enforced expression of exogenous Mieap in breast cancer cells induced caspase-dependent apoptosis, with activation of both caspase-3/7 and caspase-9. Immunohistochemistry revealed endogenous Mieap in the cytoplasm in 24/75 (32%) invasive ductal carcinomas (IDC), 15/27 (55.6%) cases of ductal carcinoma in situ (DCIS) and 16/18 (88.9%) fibroadenomas (FA) (IDC vs DCIS; P = 0.0389, DCIS vs FA; P = 0.0234, IDC vs FA; P < 0.0001). In IDC, the Mieap promoter was methylated in 6/46 (13%) cases, whereas p53 was mutated in 6/46 (13%) cases. Therefore, the p53/Mieap-regulated MQC pathway was inactivated in 12/46 IDC (26.1%). Interestingly, all tumors derived from the 12 patients with Mieap promoter methylation or p53 mutations pathologically exhibited more aggressive and malignant breast cancer phenotypes. Impairment of p53/Mieap-regulated MQC pathway resulted in significantly shorter disease-free survival (DFS) (P = 0.021), although p53 status is more prognostic in DFS than Mieap promoter methylation. These results indicate that p53/Mieap-regulated MQC has a critical role in tumor suppression in breast cancer, possibly in part through mitochondrial apoptotic pathway. PMID- 30290056 TI - Response anisocoria in the pupillary light and darkness reflex. AB - The pupil constricts or dilates in response to a luminance increase or decrease, and these transient pupillary responses are controlled by the parasympathetic and sympathetic pathways. Although pupillary responses of the two eyes are highly correlated, they are not always identical (referred to as anisocoria). For example, there are unequal direct and consensual pupillary constriction responses after an increase in luminance to one eye. While contraction anisocoria (i.e. constriction) has been demonstrated in the pupillary light reflex, it is not yet known if there is also dilation anisocoria in the pupillary darkness reflex. Unlike previous studies that focused on the pupillary light reflex, we examined response anisocoria in both pupillary light and darkness reflexes. While requiring participants to maintain central fixation, we presented a light or dark stimulus to either the right or left visual field to induce transient pupillary constriction or dilation. Both the pupillary light and darkness reflexes had significantly larger ipsilateral responses compared to the contralateral responses relative to the stimulated visual field. The observed ipsilateral effects occurred significantly faster in the light than darkness reflex, suggesting that larger ipsilateral pupillary dilation after a luminance decrease cannot be only attributed to the inhibition of the parasympathetic system, but is also mediated by the excitation of the sympathetic system. Together, our results demonstrated a larger ipsilateral pupil response in both the pupillary light and darkness reflex, indicating an asymmetry in ipsilateral and contralateral neural circuitry of the pupillary darkness reflex. PMID- 30290057 TI - Osteophytes in the Cervical Vertebral Bodies (C3-C7)-Demographical Perspectives. AB - Vertebral osteophytes are an age-dependent manifestation of degenerative changes in the spine. We aimed to determine the prevalence and severity of cervical osteophytosis in a large study population. To do so, we developed a grading system for osteophytosis, enabling the assessment of their presence and severity in the cervical spine, and applied it to the analysis of dried cervical vertebral bodies (C3-C7) from 273 individuals. Statistical analyses were carried out per motion segment, while testing for the effect of age, sex, and ethnicity. The highest prevalence of osteophytes was found in motion segment C5/C6 (48.2%), followed by C4/C5 (44.1%), and last C6/C7 and C3/C4 (40.5%). Severe osteophytes are most commonly seen in motion segment C5/C6. In all motion segments, the inferior discal surface of the upper vertebra manifests more osteophytes than the superior discal surface of the lower one. Osteophytes prevalence is sex-dependent only in the upper cervical vertebrae (C3-C4), and age- and ethnicity-dependent for all vertebrae. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30290058 TI - An in vitro and in vivo study of the role of long non-coding RNA-HOST2 in the proliferation, migration, and invasion of human glioma cells. AB - Gliomas are the most commonly occurring primary malignant brain tumors in the central nervous system of adults. They are rarely curable and the prognosis for high grade gliomas is generally poor. Recently, long non-coding RNA (lncRNA) human ovarian cancer-specific transcript 2 (HOST2) has been reported to be expressed at high levels in human ovarian cancer, involving tumorigenesis. However, little is still known about whether and how HOST2 regulates glioma development and progression. Therefore, this study aims to investigate the role of HOST2 in human glioma cells. Reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) was used to determine the expression of lncRNA HOST2, let-7b, and PBX3 in human glioma cells. Cultured human glioma cells were treated with siRNA (si)-lncRNA HOST2, let-7b mimic, si-lncRNA HOST2 + let-7b inhibitor, and si-PBX3. Parameters including cell viability, colony formation, cell migration, and cell invasion were detected by cell counting kit-8 assay, colony formation assay, scratch test, and Transwell assay respectively to determine the effects of down-regulated HOST2 on glioma cells. Tumor formation in nude mice was evaluated by subcutaneous tumor formation experiment. Results showed that HOST2 and PBX3 were highly expressed in glioma tissue whereas let-7b was expressed at much lower levels. In response to treatment with si-lncRNA HOST2, si-PBX3, and let-7b mimic, glioma cell lines exhibited decreased cell viability, suppressed cell migration, invasion, and reduced colony formation of glioma cells. This was accompanied by an attenuated tumor formation with smaller volume and weight in nude mice, suggesting that down-regulated HOST2 could inhibit the tumorigenicity of glioma cells. Lastly, we found that lncRNA HOST2 was highly expressed in glioma tissues and its down-regulation could inhibit the growth and invasion of glioma cells. (c) 2018 IUBMB Life, 2018. PMID- 30290059 TI - Critical evaluation of microextraction pretreatment techniques - Part 1: Single drop and sorbent-based techniques. AB - Sample pretreatment techniques or preconcentration constitute a very important step before the analysis of environmental, clinical, pharmaceutical, and other complex samples. Thanks to extraction techniques it is possible to achieve higher method sensitivities and selectivities. Miniaturization microextraction methods make them more environmentally friendly and only small amounts of samples are required. In the past 30 years, a number of microextraction methods have been developed and used and are documented in thousands of articles. Many reviews have been written focusing on their use in specified professional fields or on the latest trends. Unfortunately, no uniform nomenclature has been introduced for these methods. Therefore, this review attempts to classify all the essential microextraction techniques and describes their advantages, disadvantages, and the latest innovations. The methods are divided into two main groups: single drop and sorbent-based techniques according to the type of extraction phase. PMID- 30290060 TI - Aqueous Dual-Ion Battery Based on a Hematite Anode with Exposed {1 0 4} Facets. AB - The aqueous rechargeable lithium battery (ARLB) is one of the most promising devices for large-scale grid applications. Currently, a key issue for ARLBs is to develop promising anode materials with favorable electrochemical performances. Here, for the first time, we demonstrate an aqueous battery that utilizes the reversible redox reaction with hydroxide ions (OH- ) in the hematite (Fe2 O3 ) anode and a commercial Li ion intercalation compound in neutral solution as the cathode. The fabricated aqueous battery displays a reversible capacity of 92 mAh g-1 . The morphology of the used Fe2 O3 anode with exposed {1 0 4} facets for this aqueous battery is unique and attractive. Importantly, with the dual-pH neutral-alkaline hybrid electrolyte, many excellent anode materials that previously could only work in alkaline electrolytes can now be successfully combined with commercial cathodes in neutral solutions, which may significantly enrich the range of anode materials for ARLBs. In addition, the reported battery configuration can be extended to other aqueous batteries beyond Li-ion ones with lower cost. PMID- 30290061 TI - Early administration of dapagliflozin preserves pancreatic beta-cell mass through a legacy effect in a mouse model of type 2 diabetes. AB - AIMS/INTRODUCTION: The preservation of pancreatic beta-cell mass is an essential factor in the onset and development of type 2 diabetes mellitus. Recently, sodium glucose cotransporter 2 inhibitors have been launched as antihyperglycemic agents, and their organ-protective effects are attracting attention. They are also reported to have favorable effects on the preservation of pancreatic beta cell mass, but the appropriate timing for the administration of sodium-glucose cotransporter 2 inhibitors is obscure. MATERIALS AND METHODS: In the present study, we administered a sodium-glucose cotransporter 2 inhibitor, dapagliflozin, to an animal model of type 2 diabetes mellitus, db/db mice, and investigated the adequate timing and duration for its administration. We also carried out microarray analysis using pancreatic islets from db/db mice. RESULTS: We found that dapagliflozin preserved pancreatic beta-cell mass depending on the duration of administration and markedly improved blood glucose levels. If the duration was the same, the earlier administration of dapagliflozin was more effective in preserving pancreatic beta-cell mass, increasing serum insulin levels and improving blood glucose levels. From microarray analysis, we discovered that the expression of Agr2, Tff2 and Gkn3 was significantly upregulated after the early administration of dapagliflozin. This upregulated gene expression might provide a legacy effect for the preservation of pancreatic beta-cell mass. CONCLUSIONS: We expect that the early administration of dapagliflozin would provide a long lasting effect in preserving pancreatic beta-cell mass. PMID- 30290062 TI - Exploring the C-Terminal Tail Dynamics: Structural and Molecular Perspectives into the Therapeutic Activities of Novel CRMP-2 Inhibitors, Naringenin and Naringenin-7-O-glucuronide, in the Treatment of Alzheimer's Disease. AB - The collapsin response mediator protein (CRMP-2) is hyperphosphorylated in Alzheimer's disease (AD). These phosphorylation events are mediated by specific kinase proteins, GSK3beta and Cdk5, and occur at target phosphorylation sites majorly located at the C-terminal tail of CRMP-2. The abilities of naringenin (NAR) and naringenin-7-O-glucuronide (NAR-7-O-G) to selectively bind CRMP-2 and reduce its phosphorylation have been previously demonstrated; the molecular interplay between these events remains unresolved. Using computational tools, we unravel the possible mechanisms by which these molecules disrupt CRMP-2 phosphorylation. Structural and dynamic analyses revealed that while the C terminal tail of unbound CRMP-2 was extended and subtly organized, notable conformational disarray and rigidity characterized this region when bound by NAR and NAR-7-O-G. Consequentially, atomistic motions of constituent phosphorylation sites were restricted, indicative of structural occurrences that could distort the accessibility of interactive kinase proteins. A similar pattern was observed at a target phosphorylation site located in the globular domain of CRMP-2. MM/PBSA analyses revealed that both compounds interacted favorably with CRMP-2 while crucial residues that enhanced their selective binding include Glu353, Thr349, Lys254, Asp140 and Arg75. These structural insights provide mechanistic events that could contribute towards the structure-based design of anti-AD molecules which can bind CRMP2 selectively and alter its phosphorylation process. PMID- 30290063 TI - The Brain and Inner Ear of the Early Paleocene "Condylarth" Carsioptychus coarctatus: Implications for Early Placental Mammal Neurosensory Biology and Behavior. AB - Mammals underwent a profound diversification after the end-Cretaceous mass extinction, with placentals rapidly expanding in body size and diversity to fill new niches vacated by dinosaurs. Little is known, however, about the brains and senses of these earliest placentals, and how neurosensory features may have promoted their survival and diversification. We here use computed tomography (CT) to describe the brain, inner ear, sinuses, and endocranial nerves and vessels of Carsioptychus coarctatus, a periptychid "condylarth" that was among the first placentals to blossom during the few million years after the extinction, in the Paleocene. Carsioptychus has a generally primitive brain and inner ear that is similar to the inferred ancestral eutherian/placental condition. Notable "primitive" features include the large, anteriorly expanded, and conjoined olfactory bulbs, proportionally small neocortex, lissencephalic cerebrum, and large hindbrain compared to the cerebrum. An encephalization quotient (EQ) cannot be confidently calculated because of specimen crushing but was likely very small, and comparisons with other extinct placentals reveal that many Paleocene "archaic" mammals had EQ values below the hallmark threshold of modern placentals but within the zone of nonmammalian cynodonts, indicative of small brains and low intelligence. Carsioptychus did, however, have a "conventional" hearing range for a placental, but was not particularly agile, with semicircular canal dimensions similar to modern pigs. This information fleshes out the biology of a keystone Paleocene "archaic" placental, but more comparative work is needed to test hypotheses of how neurosensory evolution was related to the placental radiation. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30290064 TI - Long noncoding RNA FAL1 promotes proliferation and inhibits apoptosis of human colon cancer cells. AB - Aberrant expression of long non-coding RNAs (lncRNAs) has been associated with a variety of malignancies including colon cancer. In this study, we aimed to characterize the biological mechanisms of focally amplified lncRNA on chromosome 1 (FAL1) in colon cancers. Here, our results indicate that FAL1 expression was remarkably up-regulated in colon tumor tissues as compared to corresponding tumor adjacent normal tissues. Importantly, the cumulative survival rate of patients with high levels of FAL1 in tumor tissues was considerably lower than those with low FAL1 levels in tumor tissues. Cox regression analysis showed that lncRNA FAL1 could act as an independent prognostic factor in CRC. Knockdown of FAL1 in HT29 cells attenuated cell proliferation and stimulated cell apoptosis. In contrast, overmetastasis-related molecules Bcl-2, TGF-beta1, p65, and PCNA at the mRNA and protein levels. Mechanistically, FAL1 was found to interact with STAT3 at 200 to 400 bp and promote phosphorylation of STAT3. In addition, we found that knockdown of STAT3 in HT29 cells abolished the effects of FAL1 on cell proliferation as well as the expression of TGF-beta1 and Bcl-2. Based on these findings, we concluded that FAL1 might be a potential oncogene for the progression of colon cancer. (c) 2018 IUBMB Life, 70(11):1093-1100, 2018. PMID- 30290065 TI - Postpartum depression and child growth in Tanzania: a cohort study. AB - OBJECTIVE: To examine the association between postpartum depression and child growth in a Tanzanian birth cohort. DESIGN: Prospective cohort study. SETTING: Moshi, Tanzania. POPULATION: Pregnant women over the age of 18 who sought antenatal care at two health clinics in Moshi, and the children they were pregnant with, were assessed for inclusion in this study. METHODS: The women were interviewed twice during pregnancy and three times after birth, the final follow up taking place 2-3 years postpartum. Signs of postpartum depression were assessed approximately 40 days postpartum with the Edinburgh Postnatal Depression Scale. MAIN OUTCOME MEASURES: Child growth was assessed with anthropometric measurements at 2-3 years of age and expressed as mean z-scores. RESULTS: In all, 1128 mother-child pairs were followed throughout the duration of the study. In total, 12.2% of the mothers showed signs of postpartum depression. Adjusted mean height-for-age z-score (HAZ) was significantly lower at 2-3 years follow up for children of mothers with postpartum depression than for children of mothers without (difference in HAZ: -0.32, 95% CI-0.49 to -0.15). Adjusted mean weight for-height z-score (WHZ) was significantly increased for the children exposed to postpartum depression (difference in WHZ: 0.21, 95% CI 0.02-0.40), whereas there was no significant difference in adjusted weight-for-age z-score (WAZ; difference in WAZ: -0.04, 95% CI -0.20 to 0.12). CONCLUSIONS: We found that postpartum depressive symptoms predicted decreased linear height in children at 2-3 years of age and slightly increased weight-for-height. TWEETABLE ABSTRACT: Postpartum depression in Tanzanian mothers is associated with impaired child growth at 2-3 years of age. PMID- 30290066 TI - Thymoquinone attenuates lead-induced nephropathy in rats. AB - Kidney hazards from lead (Pb) exposure are one of the fastest growing areas of concern in toxicology today. The thymoquinone (TQ) renoprotective effect against Pb-induced nephropathy has not previously been studied. Therefore, adult male Wistar rats were treated with Pb (2000 ppm of Pb acetate in drinking water) and/or TQ (5 mg/kg/day, per os). All treatments were applied for 5 weeks. The results indicated that Pb exposure produced metal deposition, histopathological changes, functional impairment (significant elevation in plasma urea, uric acid, and creatinine levels), total antioxidant status decrease, and lipid peroxidation stimulation in the kidneys. Interestingly, TQ supplementation remarkably improved the Pb-induced renal adverse effects without significantly reducing the tissue metal accumulation. In conclusion, our data indicate for the first time a protective effect of TQ against Pb-induced nephropathy, most likely through an antioxidant mechanism. On this basis, TQ deserves more consideration and further examination as a potential therapeutic option. PMID- 30290067 TI - Being underweight in adolescence is independently associated with adult-onset diabetes among women: The Japan Nurses' Health Study. AB - AIMS/INTRODUCTION: To examine the association between adult-onset diabetes and life-course bodyweight changes. MATERIALS AND METHODS: In a cross-sectional study, 17,398 Japanese female nurses aged >=30 years completed a self administered questionnaire in 2001-2007. Bodyweight indices were calculated for three life stages: birthweight (adjusted for gestational age), body mass index (BMI) at age 18 years and current BMI. Odds ratios for being diagnosed with adult onset diabetes were calculated according to the combined bodyweight categories of two life stages: at birth and age 18 years; and at age 18 years and the survey (current). Path analysis was carried out to decompose the effect of each bodyweight index into direct and mediating effects. RESULTS: After adjustment for age at survey and parental diabetes history, "low" birthweight (<25th percentile), when combined with either "low" or "high" BMI (>=75th percentile) at age 18 years, had significant odds ratios (2.32, 95% confidence interval [CI] 1.22-4.44; 3.69, 95% CI 2.12-6.42, respectively) compared with the group of "middle" category (25th-74th percentile) at both life stages. The combination of "low" BMI at age 18 years and "high" current BMIs showed the highest odds ratio (7.97, 95% CI 3.97-16.00). Among women without parental diabetes history, "low" BMI at age 18 years showed a significantly high odds ratio (2.25, 95% CI 1.01 4.99), even when combined with the "middle" category of current BMI. Path analysis showed that both birthweight and BMI at age 18 years had a negative direct effect on adult-onset diabetes. CONCLUSIONS: Underweight at adolescence, as well as overweight, is a potential risk factor for adult-onset diabetes among Japanese women.

AB - Computational simulations of fracture healing are a valuable tool to improve fracture treatment and implants. Several finite-element models have been established to predict callus formation due to mechanobiological rules. This work provides a comprehensive simulation for virtual implantation through the combination of callus simulation and finite-element structural synthesis (FESS) of (re-)modeling during and after healing based on Pauwel's theory of histogenesis and Wolff's law. The simulation is based on a linear elastic material model and includes generation of fracture hematoma and initial mesenchymal stem cell concentration out of an unspecified solid, cell proliferation, migration, and differentiation due to mechanical stimuli and time dependent axial loading. Three nondisplaced femoral shaft fractures with initial interfragmentary movement of 0.2, 0.6, and 1 mm and one fracture with 4 mm translation are modeled. The predictions of interfragmentary movement during fracture healing, healing success, and healing time agree with observed clinical outcome, animal models, and other numerical models. Initial interfragmentary movement between 0.2 and 1 mm leads to healing success, with the fastest healing occurring at 0.2 mm. The model of the dislocated fractures shows no further bending after remodeling and is loaded with physiological stress of -13 MPa. Ideal load-time graphs may give insight into the bone's ability to withstand loads as healing time progresses, and thus holds potential for applications in rehabilitation planning. Better knowledge of the forces present during fracture healing is needed to deploy simulations for surgical planning and manufacturing of patient individualized implants. Anat Rec, 2018.

AB - The culture of Chinese Hamster Ovary (CHO) cells for modern industrial applications, such as expression of recombinant proteins, requires media that support growth and production. Such media must support high viable cell densities while also stimulating the synthesis and extracellular transport of biologic products. Early media development efforts in this area yielded basic formulations to sustain growth, viability, and cellular function, albeit comprising animal sourced components, and complex constituents used in batch culture mode. Subsequent improvements included the development of serum-free and chemically defined (CD) media, the identification of critical nutrients, growth factors, and potentially inhibitory or toxic cellular metabolites, and the use of fed-batch and perfusion culture techniques to optimize nutrient delivery while minimizing accumulation of unwanted waste products. This review is comprised of sections covering milestones in the evolution of mammalian cell culture media, nutrient composition and formulation requirements, optimization strategies, consistency and scalability of powder and liquid media preparation for industrial applications, and key recent advances driving progress in CHO cell culture medium design and development.

AB - Although minor salivary glands play a significant functional role in the oral cavity, their developmental morphology and cell differentiation has been scarcely studied. This study aimed to describe the development of rat palatine glands with regard to the ultrastructural morphology of the secretory cells and surrounding myoepithelial cells (MECs). Palatine glands from rats at embryonic ages (E) 18 and 20 days, and postnatal days (PN) 0, 3, 7, 10, 13, 21, 30, 42, and 60 were fixed and prepared for morphological analysis and immunocytochemical labeling of alpha-smooth muscle actin (alpha-SMA). At E18, epithelial cords were observed extending from the palatal epithelium and showed negative reactivity to alpha SMA. After luminization at E20, the cells of immature acini accumulated secretory granules of various densities: electron-dense, electron-lucent and some empty appearing granules. MECs were poorly differentiated at E20 and exhibited only slight alpha-SMA expression. At birth, mucous and serous cells were typically located around a common lumen. Thereafter, serous cells began to move to the periphery to form demilunes by PN7. The mucous secretory granules of intermediate electron density became predominant around PN13. At PN21, these granules were dramatically reduced in number and most of the acini in adults contained acinar cells with numerous electron-lucent granules, and a few serous demilune cells with electron-dense granules. After birth, MECs progressively accumulated actin microfilaments until prominent alpha-SMA expressing MECs invested the acini and the proximal part of the intercalated ducts in the adult.

PMID- 30290074 TI - Restoration of myocardial glucose uptake with facilitated myocardial glucose transporter 4 translocation contributes to alleviation of diabetic cardiomyopathy in rats after duodenal-jejunal bypass. AB - AIMS/INTRODUCTION: Duodenal-jejunal bypass (DJB) surgery has been reported to effectively relieve diabetic cardiomyopathy (DCM). However, the specific mechanisms remain largely unknown. The present study was designed to determine the alterations of myocardial glucose uptake (MGU) after DJB and their effects on DCM. MATERIALS AND METHODS: Duodenal-jejunal bypass and sham surgeries were carried out in diabetic rats induced by a high-fat diet and a low dose of streptozotocin, with chow-diet fed rats as controls. Bodyweight, food intake, glucose homeostasis and lipid profiles were measured at indicated time-points. Cardiac function was evaluated by transthoracic echocardiography and hemodynamic measurement. Cardiac remodeling was assessed by a series of morphometric analyses along with transmission electron microscopy. Positron-emission tomography with fluorine-18 labeled fluorodeoxyglucose was carried out to evaluate the MGU in vivo. Furthermore, myocardial glucose transporters (GLUT; GLUT1 and GLUT4), myocardial insulin signaling and GLUT-4 translocation-related proteins were investigated to elucidate the underlying mechanisms. RESULTS: The DJB group showed restored systolic and diastolic cardiac function, along with significant remission in cardiac hypertrophy, cardiac fibrosis, lipid deposit and ultrastructural disorder independent of weight loss compared with the sham group. Furthermore, the DJB group showed upregulated myocardial insulin signaling, hyperphosphorylation of AKT substrate of 160 kDa (AS160) and TBC1D1, along with preserved soluble N-ethylmaleimide-sensitive factor attachment protein receptor proteins, facilitating the GLUT-4 translocation to the myocardial cell surface and restoration of MGU. CONCLUSIONS: The present findings provide evidence that restoration of MGU is implicated in the alleviation of DCM after DJB through facilitating GLUT-4 translocation, suggesting a potential choice for treatment of human DCM if properly implemented. PMID- 30290075 TI - Combating Excessive Eating: A Role for Four Evidence-Based Remedies. AB - OBJECTIVE: The aim of this study is to review the control of energy balance and outline some causes of and remedies for excessive energy intake. METHODS: A narrative review was conducted. RESULTS: There is negative feedback control of energy intake and body weight, but, nonetheless, energy intake is only loosely coupled with energy expenditure. Consequently, we are vulnerable to eating in excess of energy requirements. In this context, energy density, portion size, and habitual meal patterns have strong influences on energy intake and, accordingly, can be targeted to reduce energy intake. For example, energy density can be reduced without much affecting food reward (approximately the pleasure gained from eating) because their relationship is such that reward value is affected relatively little by increments in energy density above 1.5 kcal/g. This and other strategies that increase reward per calorie eaten may be superior to increasing the satiety effect of products because fullness is not inherently rewarding. Low-calorie sweeteners provide a means to reduce energy density while largely preserving food or beverage reward value. Consistent with this, consumption of low-calorie sweeteners compared with consumption of sugars has been found to reduce energy intake and body weight. CONCLUSIONS: Understanding what causes excessive eating also provides insights into how to combat this problem. PMID- 30290076 TI - Low-Calorie Sweeteners: Exploring Underutilized Database Resources to Understand Dietary Patterns and Obesity. AB - The use and impact of low-calorie sweeteners (LCS) in relation to the national challenges of overweight and obesity are complex and controversial. Most research on LCS have focused on the prevalence of consumption of LCS in beverages. The 2015 Dietary Guidelines Advisory Committee emphasized dietary patterns and health rather than a focus on specific nutrients or foods. The committee took this approach to shift the national emphasis onto the context of total rather than individual nutrient consumption. A broader research paradigm is needed to elucidate the actual exposure to LCS and how they are consumed within dietary patterns in the US population. National-level databases exist that can be used to broaden scientific understanding of the effects of LCS and health outcomes. These databases are underutilized, and they provide potential tools for grasping a fuller picture of LCS in the US diet. PMID- 30290077 TI - Oral Post-Oral Actions of Low-Calorie Sweeteners: A Tale of Contradictions and Controversies. AB - OBJECTIVE: Many scientists and laypeople alike have concerns about low-calorie sweeteners (LCSs). These concerns stem from both a dissatisfaction with the taste of LCSs and reports that they cause metabolic disruptions (e.g., weight gain, glucose intolerance). METHODS: This article provides a critical review of the literature on LCSs from the standpoint of their taste, gastrointestinal, and metabolic effects; biological fate in the body; and impact on ingestion and glucose homeostasis. RESULTS AND CONCLUSIONS: Mammals can readily discriminate between LCSs and sugars because both types of sweetener activate distinct oral and post-oral sensory pathways. LCSs differ in their ability to access post-oral tissues, but few studies have incorporated this observation into their design. It is difficult to extrapolate results between mice, rats, and humans because of interspecies differences in the taste and post-oral actions of LCSs and the fact that investigators often use different response measures in rodents and humans. There is confounding in the experimental design of some of the most widely cited studies of LCS-induced metabolic disruptions. The uncritical acceptance of these studies has generated considerable controversy. More work is needed to obtain a clearer understanding of the metabolic effects of LCSs.

AB - AIMS/INTRODUCTION: To evaluate the contribution of pancreatic alpha-cell function to the dawn phenomenon, insulin sensitivity, hepatic glucose uptake and glycemic variability in patients with type 1 diabetes. MATERIALS AND METHODS: In 40 patients with type 1 diabetes, arginine stimulation tests were carried out, and the area under the curve (AUC) of glucagon was measured using radioimmunoassays (AUCglc RIA ) and enzyme-linked immunosorbent assays (AUCglc ELISA ). The ratio of the insulin dose delivered by an artificial pancreas to maintain euglycemia between 04.00 and 08.00 hours or between 00.00 and 04.00 hours was measured as the dawn index. The glucose infusion rate and hepatic glucose uptake were measured using hyperinsulinemic euglycemic clamp and clamp oral glucose loading tests. Glycemic variability in 96 h was measured by continuous glucose monitoring. RESULTS: The median dawn index (1.7, interquartile range 1.0-2.8) was not correlated with AUCglc RIA (R2 = 0.03, P = 0.39) or AUCglc ELISA (R2 = 0.04, P = 0.32). The median glucose infusion rate (7.3 mg/kg/min, interquartile range 6.4-9.2 mg/kg/min) was significantly correlated with AUCglc RIA (R2 = 0.20, P = 0.02) and AUCglc ELISA (R2 = 0.21, P = 0.02). The median hepatic glucose uptake (65.3%, interquartile range 40.0-87.3%) was not correlated with AUCglc RIA (R2 = 0.07, P = 0.26) or AUCglc ELISA (R2 = 0.26, P = 0.79). The standard deviation of glucose levels measured by continuous glucose monitoring was significantly correlated with AUCglc RIA (R2 = 0.11, P = 0.049), but not with AUCglc ELISA (R2 = 0.01, P = 0.75). CONCLUSIONS: Pancreatic alpha-cell function contributed to insulin sensitivity in patients with type 1 diabetes.

AB - Recently two atomic resolution crystal structures of Photosystem II, in the double flashed, nominal S3 intermediate state of its Mn4 Ca water oxidising complex (WOC), have been presented (Young et al., Nature 2016, 540, 453; Suga et al., Nature 2017, 543, 131). These structures are at 2.25 A and 2.35 A resolution, respectively. Although highly similar in most respects, the structures differ in a key region within the WOC catalytic site. In the 2.25 A structure, one oxy species (O5) is observed within the WOC cavity, weakly associated with the Mn centres, similar to that seen earlier in the 1.95 A XRD structure of the S1 intermediate (Suga et al., Nature, 2015, 517, 99). In the 2.35 A structure, two such species are seen (O5, O6), with the Mn centres and O5 positioned as in the 2.25 A structure and an O5-O6 separation of ~1.5 A, consistent with peroxo formation. This suggests O5 and O6 are substrate water derived species in this double flashed form. Recently we have presented (Petrie, et al., Chem. Phys. Chem., 2017) a large scale (220 atom) quantum chemical model of the Young et al. 2.25 A structure, which quantitatively explains all significant features within the WOC region of that structure, particularly the positions of the metal centres and O5 group. Critical to this was our assumption of a 'low' Mn oxidation paradigm (mean S1 Mn oxidation level of +3.0, Petrie et al., Angew. Chem. Int. Ed., 2015), rather than a 'high' oxidation model (mean S1 oxidation level of +3.5), widely assumed in the literature. Here we show that our same oxidation state model predicts two classes of energetically close S3 structural forms, analogous to the S1 state, one with the metal centres and O5 positioned as in the 2.25 A structure, and the other with the metals similarly placed, but with O5 located in the O6 position of the 2.35 A structure. We show that the Suga et al. 2.35 A structure is likely a superposition of two such forms, one from each class, which is consistent with reported atomic occupancies for that structure and the relative total energies we calculate for the two structural forms. PMID- 30290081 TI - Redesign of a New Manganese Peroxidase Highly Expressed in Pichia pastoris towards a Lignin-Degrading Versatile Peroxidase. AB - Manganese peroxidases, lignin peroxidases, and versatile peroxidases secreted by white rot fungi are supposed to play an essential role in lignin degradation. Thus, these enzymes have attracted significant attention as potential biocatalysts. Versatile peroxidases are the most interesting ones, since they comprise activities of manganese and lignin peroxidases. Herein, we demonstrate how the properties of a new manganese peroxidase from Moniliophthora roreri, designated MrMnP1, were shifted towards those of a versatile peroxidase. MrMnP1 was cloned in Pichia pastoris X-33 and highly expressed in a fed-batch fermentation, yielding 132 mg L-1 of active enzyme. To extend the substrate spectrum of MrMnP1, a catalytically active tryptophan present in lignin and versatile peroxidases was first introduced. Additionally, the role of five amino acids at positions adjacent to the catalytic tryptophan was elucidated through their replacement by those found in a versatile peroxidase from Pleurotus eryngii. The resulting mutants demonstrated new activities towards high-redox potential substrates, such as lignin dimers, veratryl alcohol, and the azo dye Reactive Black 5. PMID- 30290082 TI - Autophagy Induction Plays Time-Dependent Role in Viral Load of HCV Infected Huh7.5 Cell Line. AB - Autophagy provides an initial membranous platform for incoming hepatitis C virus (HCV) RNA translation and immune evasion. Once HCV replication is established, this infrastructure will be unnecessary for translation of HCV RNA progeny. So, the autophagy plays key role in the replication and immune pathogenesis of HCV virus. The aim of this study was to study the effect of autophagy induction in Huh7.5 cell on virus titer. The Huh7.5 cell was transfected with recombinant pcDNA-Beclin1. The autophagy induction was evaluated via microtubule associated protein 1 light chain 3 staining as autophagy formation marker using flow cytometry. The HCV (JFH1) was inoculated 12-h post-transfection. Next, to evaluate the viral load, viral RNA was extracted after 24 and 48 h and virus titer was calculated using real-time PCR. The result of the current study shows that the induction of autophagy before virus infection was able to enhance virus yield from 4 * 103 copies/mL to 1 * 104 copies/mL at 24-h post-infection, but reduced viral load after 48 h up to 6 * 103 copies/mL. The study of cross-talk between autophagy and HCV may bring new hope for human intervention and treatment of HCV. Also, it opens new avenue to improve virus cultivation in cell culture and understanding HCV and host cell responses. (c) 2018 IUBMB Life, 2018. PMID- 30290083 TI - The Embryonic Ascent of the Kidney Revisited. AB - Although the embryonic kidney's ascent is well established, the intermediate morphological changes that occur during the process are unclear. To evaluate the morphological events that accompany the kidney's ascent, we examined serial sagittal sections from 24 embryos at 5-7 weeks gestation. Six specimens had bilaterally ascending kidneys that were between the levels of the second to fifth lumbar vertebrae, and each kidney had a primitive renal cortex surrounding clusters of ampullae, which branched from the pelvis, and a dense tissue band that connected the renal cortex with the embryonic adrenal cortex or celiac ganglia, and there was no adipose capsule or renal artery. The tissue band contained abundant nerve twigs from the major splanchnic nerve; thus, it was conceivable that it was sufficiently rigid to support the length of the retroperitoneal tissue mass that included the embryonic adrenal cortex, celiac ganglia, and kidney. The lumbar vertebral body's height was much shorter than that of the ascending kidney. However, the lower vertebral column's curvature was often maintained, even when the kidneys had ascended. Therefore, vertebral column straightening was not the only factor required to drive the ascent. Together with the growth of the thorax and liver, the adrenal cortex, ganglia, and kidney appeared to change simultaneously at a position relative to the vertebrae. The renal artery established a connection to the renal cortex after the ascent. Evaluations of frontal sections from five additional specimens suggested that from its initial position, the kidney extended upwards between bilateral umbilical arteries. Anat Rec, 2018.

PMID- 30290084 TI - High-Fat Diet, Betaine, and Polydextrose Induce Changes in Adipose Tissue Inflammation and Metabolism in C57BL/6J Mice. AB - SCOPE: High-fat diets are a likely cause of low-grade inflammation and obesity related pathologies. This study measures the effects of a high-fat diet, in combination with two dietary supplements-betaine and polydextrose-on metabolism and inflammation in the adipose tissue of diet-induced obese mice. METHODS AND RESULTS: Forty male C57BL/6J mice are fed a high-fat diet for 8 weeks and compared with low-fat-diet-fed control animals (n = 10). For the last 4 weeks, the high-fat-diet-fed animals are supplemented with 1% betaine, 3.33% polydextrose, their combination, or plain water. Fat depots from subcutaneous and visceral adipose tissue are analyzed for inflammatory markers and nontargeted metabolomics by quantitative PCR and LC-QTOF-MS. The high-fat diet significantly increases adipose tissue inflammation in both fat depots. By metabolic profiling, clear differences are noted between low-fat-diet and high-fat-diet groups with regard to the levels of several metabolite species-primarily carnitines, lipids, and amino acids. Dietary betaine mitigates the high-fat-diet-induced IL-6 expression and significantly increases betaine and butyrobetaine levels in adipose tissue. CONCLUSIONS: The high-fat diet induces patent changes in carnitine and lipid metabolism in adipose tissue. Betaine supplementation elevates the levels of betaine and its derivatives and certain carnitine species, as reported in muscle and liver, and moderately reduces inflammation.

AB - INTRODUCTION: Diagnosis of myelodysplastic syndromes (MDSs) when anemia is the only abnormality can be complicated. The aim of our study was to investigate the primary causes of anemia and/or macrocytosis of uncertain etiology. METHODS: We conducted a multicenter, prospective study over 4 months in three hematology laboratories. In step 1, we used an automated informatics system to screen 137 453 hemograms for cases of anemia and/or macrocytosis (n = 2702). In step 2, we excluded all patients whose anemia appeared to be due to a known cause. This left 290 patients had anemia of uncertain etiology. In step 3, we conducted further investigations, including a peripheral blood smear, and analysis of iron, vitamin B12, folate, and thyroid hormone levels. RESULTS: A differential diagnosis was obtained in 139 patients (48%). The primary causes of anemia were iron deficiency (n = 59) and megaloblastic anemia (n = 39). In total, 25 hematologic disorders were diagnosed, including 14 patients with MDS (56%). The median age of MDS patients was 80 years, 12 had anemia as an isolated cytopenia, and most (n = 10) had lower-risk disease (IPSS-R <= 3.5). SF3B1 mutations were most frequent (n = 6) and correlated with the presence of ring sideroblasts (100%) and associated with better prognosis (P = 0.001). CONCLUSIONS: Our prospective, four-step approach is an efficient and logical strategy to facilitate the diagnosis of MDS on the basis of unexplained anemia and/or macrocytosis, and may allow the early diagnosis of the most serious causes of anemia. Molecular analysis of genes related to MDS could be a promising diagnostic and prognostic approach. PMID- 30290086 TI - Results of Questionnaire Survey on Gross Anatomy Education (March 2014).

AB - When providing dental treatment, the dental clinician (DC) is expected to be knowledgeable in recognition and emergency management of an allergic response. Common manifestations of localized allergic responses can present as a rash or hives (urticaria), running of the nose, and swelling of the lips, eyes, face, respiratory and gastrointestinal mucosa. More critically, there is the potential for breathing difficulties from laryngeal swelling. Airway obstruction can be potentially life threatening.' Anaphylactic shock can be another serious reaction. Although most of these allergic responses can be minimal and managed with an antihistamine (diphenhydramine), more serious allergic reactions (marked breathing difficulty, anaphylaxis) may require the use of an intramuscular injection of epinephrine. This case report describes a patient who had what appeared to be a common allergic response to some aspect of dental materials or treatment but was subsequently diagnosed with an allergic condition known as angioedema (AE) that had the potential to be non-responsive to dental office emergency medications. AE may be due to the more common histamine generated process as described below. However, if the patient's AE is due to alternate pathophysiology, the DC may not be able to manage breathing difficulties due to airway swelling, which could be rapidly fatal.

PMID- 30290093 TI - Comparison of Laser Versus Rotary Instrumentation- A Case Study. AB - The use of an erbium laser to treat carious teeth has proven to have several advantages when compared to rotary instruments. The clinician is able to remove a minimal amount of tooth structure, thus minimizing the risk of pulpal exposure. The extremely short pulses of erbium lasers combined with an aerosolized water spray have been shown to cool the pulp as opposed to rotary instruments which may create heat that could lead to a pulpitis. Bonding to the lased surfaces is improved because the smear layer is removed, bleeding is controlled, and the lased tooth surface appears etched with open dentinal tubules. The laser also provides a bactericidal effect and the need for local anesthetics is eliminated or reduced. The use of the erbium laser to prepare cavity preparations can be done as quickly, or oftentimes more quickly, than using a rotary instruments. In addition, patients appreciate the absence of the high speed drill noise and vibration.

AB - The success of composite restorations requires meticulous clinical technique in addition to reliable restorative materials and armamentarium. Early failure of restorations is undesirable and are usually replaced at no cost to patients. A metaanalysis study reported a mean annual failure rate of 1.46% for posterior composite restorations. At the University of Tennessee Health Science Center College of Dentistry (UTHSC CoD) predoctoral clinic the percentage of posterior composite restorations replaced within 12 months, retrieved from 2007-2014 electronic chart 'redo' records, was on average 0.58%. Several factors may have contributed to the quality of composite restorations placed by novice clinicians with modest experience. Student doctors are educated about composite placement in preclinical courses and then work under close supervision during their clinical training. This article describes restorative techniques for composites and the rationales taught at the UTHSC CoD Department of Restorative Dentistry.

AB - OBJECTIVE: To document the evolving economies of dental establishments in the State of Tennessee during a period of significant growth of the number of establishments before and after the "Great Recession." METHOD: Published results from the five-year economic surveys by the U.S. Census Bureau on business receipts and salaries of employees (including dentists) for the State of Tennessee and its counties were used to construct a review of these developments. RESULTS: Between 2007 and 2012, there were continued increases in average current dollar business receipts and employee salaries. However, in terms of standard dollars, removing the effects of inflation: 1) business receipts increased in 19 counties but decreased in 37 counties; 2) employee salaries increased in 13 counties but decreased in 30 counties. CONCLUSIONS: Results are in line with the reports by the ADA Health Policy Institute, which indicate that nationally the percentage of dentists who report they are not busy enough has increased and dentists' earnings are stagnating. The need is to expand the delivery of care to underserved populations, including the poor, individuals with disabilities, minorities and new immigrant populations, for whom oral health services may not be a priority commodity.

AB - OBJECTIVE: The evaluation of hard and soft tissue relationships is an important part of the study of facial morphology, craniofacial development and orthodontic treatment and outcomes. Historically, this evaluation has occurred in two dimensions. The purpose of this study was to develop a protocol to study the relationships of hard and soft tissues in three dimensions without the use of additional radiation. MATERIALS AND METHODS: Stereo photogrammetric images created by the 3dMDTM Face system and models digitized using the Motion View scanner were utilized. Using a previous lateral cephalometric image from the orthodontic records appointment, these hard tissue and soft tissue images were integrated. RESULTS: The integration of all data sets was accomplished with an average error rate of less than .05mm. A method was developed, thus allowing measurement of soft tissue thicknesses and changes over treatment time in relation to the underlying dentition. CONCLUSIONS: Evaluation of hard and soft tissue relationship in three dimensions can be accomplished without the use of additional radiographic studies.

AB - : Neuroleptic cardiomyopathy (NCMP) is a consequence of cardiotoxic side effect of antipsychotic drugs. Changes of ECG associated with this condition are poorly known. Aim: To elucidate dynamics of ECG at different clinical stages of NCMP and evaluate its diagnostic value. Methods. We determined the frequency and informative values of 8 different ECG signs includingQTinterval corrected based at theBazettformula (QTc). Their informative value was estimated from the Kullback formula. The data obtained were analyzed by parametric and non parametric statistics methods. Results: Pathological changes of ECG parameters associated with NCM Preflect processes of structural rearrangement in the heart at different levels of its organization. The analysis of the available information showed that almost all ECG parameters have high diagnostic value listed in the following rank order (frequency/informativeness): rhythm disorder - 1/8, prolongation of the QTc interval - 4/3, conduction disorder - 2/2, diffuse muscular changes - 3/1, right heart overload - 5/6, left ventricular hypertrophy 7-8/5, impaired electrical activity of myocardium - 7-8/5, deviation of the electrical axis to the left - 6/4. It seems appropriate to distinguish the following three maximally informative (and therefore most important) ECG signs indicative of developing NCMP: diffuse muscular changes, conduction disorder, and prolongation of the QTc interval. Conclusion: The analysis of the available information provides a new insight into dynamics of ECG signs associated with NCMP and permits to estimate the diagnostic value of pathological changes for its earlier detection.

AB - Attempts at optimizing classification of chronic obstructive pulmonary disease (COPD) reflect clinical heterogeneity of this pathology and provide a basis for the search of new phenotypic markers (especially at the early stages of the disease) that could be useful for prognostication of its severity in individual patients. One of the potential makers is phenotyping of COPD with distinguishing bronchitic, emphysemic, and mixed phenotypes. This paper presents results of analysis of functional characteristics of the patients with these phenotypes. They are shown to reflect clinical and functional features of the disease that may be of value for diagnostic purposes, the choice of the treatment strategy and prognosis of the outcome in individual patients.

AB - Aim: To study the influence of renal anemia on the clinical course of chronic kidney disease in patients with chronic glomerulonephritis (CGN) at the early stage of the disease. Materials and methods: This prospective 12 month study included evaluation of clinical and laboratory characteristics of 149 patients aged 17-66 (mean 37,6+/-12,6) years at the pre-dialysis stage of CGN (92 men (37,04+/-13,4 yr) and 57 women (38,2+/-11,2 yr). Results: By the end of prospective observation, patients of group 1 (CGN without anemia) showed a decrease of the hemoglobin level accompanied by the impairment of nitrogen releasing function with the glomerular filtration rate of 70,1 (43,1-111) ml/min compared with 87 (61,3-115,3) at the onset of observations (p<0,05). In group 2 (CGN with anemia), dynamics of the nitrogen-releasing function was similar but even more pronounced with the glomerular filtration rate reduced to 47,4 (32,2 91,8) ml/min compared with 80,7 (39,8-107,9) at the onset of observations (p<0,05) and the serum creatinine level increased to157 (92-242) mcmol/l compared with 123 (86-171) (p<0,05). Conclusion: Reduction of hemoglobin level in patients with CGN is apparent at the early stages of the disease in association with impairment of glomerular filtration. The data obtained indicate that anemia can be a laboratory predictor of deteriorated nitrogen-releasing function.

AB - Patients with diabetes mellitus (DM) are at risk of development of both diabetic foot syndrome and ulcers on the lower legs due to chronic venous insufficiency and other factors. The main group in this study was comprised of diabetic patients with ulcers of different etiology (venous, post-traumatic, mixed) treated at the Diabetic Foot Cabinet during 5 years (n=101). The group of comparison included simultaneously treated patients with diabetic foot syndrome (n=721). Patients of the main group was dominated by women (71%) and patients with type 2 DM. Ulcer healing due to the treatment, persistent non-healing ulcers, and high-level amputations occurred equally often in the two groups: 60 and 58%, 18 and 15%, 4 and 5% respectively (r>0,05). Lower leg ulcers in DM are very persistent and constitute a serious medico-social problem to be addresses based at Diabetic Foot cabinets. The frequency of such ulcers and related amputations must be taken into consideration in epidemiological surveys. PMID- 30290104 TI - [A case of mucoviscidosis in practical work of a pulmonologist].

PMID- 30290115 TI - Renewable Hydride Donors for the Catalytic Reduction of CO2: A Thermodynamic and Kinetic Study. AB - Increasing atmospheric CO2 concentration and dwindling fossil fuel supply necessitate the search for efficient methods for CO2 conversion to fuels. Assorted studies have shown pyridine and its derivatives capable of (photo)electrochemically reducing CO2 to methanol, and some mechanistic interpretations have been proposed. Here, we analyze the thermodynamic and kinetic aspects of the efficacy of pyridines as hydride-donating catalytic reagents that transfer hydrides via their dihydropyridinic form. We investigate both the effects of functionalizing pyridinic derivatives with electron-donating and electron-withdrawing groups on hydride-transfer catalyst strength, assessed via their hydricity (thermodynamic ability) and nucleophilicity (kinetic ability), and catalyst recyclability, assessed via their reduction potential. We find that pyridines substituted with electron-donating groups have stronger hydride-donating ability (having lower hydricity and larger nucleophilicity values), but are less efficiently recycled (having more negative reduction potentials). In contrast, pyridines substituted with electron-withdrawing groups are more efficiently recycled, but are weaker hydride donors. Functional group modification favorably tunes hydride strength or efficiency, but not both. We attribute this problematic coupling between the strength and recyclability of pyridinic hydrides to their aromatic nature and suggest several avenues for overcoming this difficulty. PMID- 30290116 TI - Ionic-Strength Effects on the Reactive Uptake of Ozone on Aqueous Pyruvic Acid: Implications for Air-Sea Ozone Deposition. AB - A vertical wetted-wall flow-tube technique was used to explore the ionic strength effects at the air-water interface in mediating the sea-surface reaction between ozone (O3) and pyruvic acid (PA). The uptake coefficients of ozone on aqueous PA increase substantially with the concentrations of bromide (Br-) ions, clearly indicating that the dry deposition of ozone could be significantly enhanced due to the presence of carbonyl compounds such as PA at the bromide-rich sea surface. Based on the observed uptake coefficients, the estimated deposition velocity of ozone (100 ppb) for a nanomolar range of PA concentrations is ~1 * 10-3 m s-1, which represents a significant contribution to the known deposition velocity of ozone at the sea surface. The analysis of reaction products by ultra-high resolution Fourier transform-ion cyclotron resonance mass spectrometry suggests the formation of oligomers during both the dark and light-induced heterogeneous reactions between gaseous O3 and PA occurring at the surface of a dilute aqueous phase (representative of cloud droplets). The detected high-molecular-weight compounds are much more complex than the oligomeric species identified during the photolytic degradation of bulk aqueous PA alone. PMID- 30290117 TI - Real Time Normalization of Fast Photochemical Oxidation of Proteins Experiments by Inline Adenine Radical Dosimetry. AB - Hydroxyl radical protein footprinting (HRPF) is a powerful method for measuring protein topography, allowing researchers to monitor events that alter the solvent accessible surface of a protein (e.g., ligand binding, aggregation, conformational changes, etc.) by measuring changes in the apparent rate of reaction of portions of the protein to hydroxyl radicals diffusing in solution. Fast Photochemical Oxidation of Proteins (FPOP) offers an ultrafast benchtop method for radical generation for HRPF, photolyzing hydrogen peroxide using a UV laser to generate high concentrations of hydroxyl radicals that are consumed on roughly a microsecond time scale. The broad reactivity of hydroxyl radicals means that almost anything added to the solution (e.g., ligands, buffers, excipients, etc.) will scavenge hydroxyl radicals, altering their half-life and changing the effective radical concentration experienced by the protein. Similarly, minute changes in peroxide concentration, laser fluence, and buffer composition can alter the effective radical concentration, making reproduction of data challenging. Here, we present a simple method for radical dosimetry that can be carried out as part of the FPOP workflow, allowing for measurement of effective radical concentration in real time. Additionally, by modulating the amount of radical generated, we demonstrate that effective hydroxyl radical yields in FPOP HRPF experiments carried out in buffers with widely differing levels of hydroxyl radical scavenging capacity can be compensated on the fly, yielding statistically indistinguishable results for the same conformer. This method represents a major step in transforming FPOP into a robust and reproducible technology capable of probing protein structure in a wide variety of contexts. PMID- 30290118 TI - Woven Kevlar Fiber/Polydimethylsiloxane/Reduced Graphene Oxide Composite-Based Personal Thermal Management with Freestanding Cu-Ni Core-Shell Nanowires. AB - Thermotherapy is a widespread technique that provides relief for muscle spasms and joint injuries. A great deal of energy is used to heat the surrounding environment, and heat emitted by the human body is wasted on our surroundings. Herein, a woven Kevlar fiber (WKF)-based personal thermal management device was fabricated by directly growing vertical copper-nickel (Cu-Ni) nanowires (NWs) on the WKF surface using a hydrothermal method. The treated WKF was combined with reduced graphene oxide (rGO) dispersed in polydimethylsiloxane (PDMS) to form composites using vacuum-assisted resin transfer molding (VARTM). This WKF-based personal thermal management system contained a conductive network of metallic NWs and rGO that promoted effective Joule heating and reflected back the infrared (IR) radiation emitted by the human body. It thus behaved as a type of thermal insulation. The Cu-Ni NWs were synthesized with a tunable Ni layer on Cu core NWs to enhance the oxidation resistance of the Cu NWs. The combined effect of the NW networks and rGO enabled a surface temperature of 70 degrees C to be attained on application of 1.5 V to the composites. The Cu3Ni1-WKF/PDMS provided 43% more thermal insulation and higher IR reflectance than bare WKF/PDMS. The absorbed impact energy and tensile strength was highest for the Cu1Ni3- and rGO-integrated WKF/PDMS samples. Those Cu-Ni NWs having higher Ni contents displayed better mechanical properties and those with higher Cu contents showed higher Joule heating performance and IR reflectivity at a given rGO loading. The composite shows sufficient breathability and very high durability. The high flexibility of the composites and their ability to generate sufficient heat during various human motions ensures their suitability for wearable applications. PMID- 30290119 TI - CRISPro: An Automated Pipeline for Protein Conformation Stabilization by Proline. AB - Recent studies have shown that the yield, antigenicity, and immunogenicity of an immunogen can be enhanced by stabilizing it into a specific conformation. Such stabilization often involves the engineering of proline mutations at residue positions where a proline is structurally compatible with the target conformation but not with an alternative conformation. However, there is no publicly available tool that can design proline mutations for this purpose automatically. Here we implemented an automated tool, CRISPro, that inputs structural coordinates of the target conformation and/or an alternative conformation and outputs a list of residue positions where proline mutations are predicted to stabilize the target conformation based on compatibility of phi-psi angles, secondary structure, and steric constraints. Thus, CRISPro can be used to engineer immunogens into specific conformation and to design serologic probes, capable of isolating antibodies that recognize a target shape.

PMID- 30290122 TI - Cell-Based Therapy for Bronchopulmonary Dysplasia in Preterm Infants: Workshop report. AB - Bronchopulmonary dysplasia (BPD) is the most common complication of extreme prematurity. Currently, there is no specific treatment available. Preclinical studies support cell-therapy as a promising therapy for BPD in preterm infants. A successful translation to a safe and effective clinical intervention depends on multiple factors including the perspective of neonatal health care providers. A 2 hour workshop with 40 Canadian neonatologists was held to enhance the design of a phase II trial of stem cells for babies at risk for BPD, with a focus on the population to target and the outcomes to measure in such a trial. The consensus was that infants recruited in an early trial of stem cells should be the ones with the highest risk of developing severe BPD. This risk should be established based on known antenatal, perinatal and postnatal risk factors. The primary outcome in a phase II trial will be focussed on a non-clinical outcome (e.g. a dose finding- or a safety-study). With other aspects of a translational study discussed, this workshop contributed to accelerate the design of a first Canadian clinical cell-therapy study for BPD in preterm infants. PMID- 30290123 TI - Inhibition of microRNA-155 attenuates concanavalin-A-induced autoimmune hepatitis by regulating Treg/Th17 cell differentiation. AB - Autoimmune hepatitis (AIH) is a chronic progressive autoimmune disease characterized by hepatic inflammation. This study aimed to investigate the effect of antagomir-155 on concanavalin A (ConA)-induced AIH, and its possible mechanisms. According to the results, the expression of miR-155 was raised in liver tissues after 48 h exposure to ConA. Treatment with antagomir-155 attenuated ConA-induced liver injury in mice by reducing serum alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase levels. In addition, antagomir-155 significantly alleviated the differentiation of Treg/Th17 cells in the livers of AIH mice, and suppressed Th17-cells-mediated production of pro-inflammatory cytokines IL-17A, IL-23, but not Treg-cells-mediated production of anti-inflammatory cytokine IL-10. Finally, the beneficial effect of antagomir 155 on ConA-induced AIH was abolished by administration of recombinant IL-17A. Our data demonstrated that antagomir-155 treatment could prevent AIH via regulating the differentiation of Treg and Th17 cells, suggesting that microRNA 155 may be an intriguing therapeutic target of AIH. PMID- 30290124 TI - Myeloid TBK1 Signaling Contributes to the Immune Response to Influenza. AB - Macrophages provide key elements of the host response to influenza A virus (IAV) infection, including expression of type I interferon (IFN) and inflammatory cytokines and chemokines. TANK-binding kinase 1 (TBK1) contributes to IFN expression and anti-viral responses in some cell types, but its role in the innate response to IAV in vivo is unknown. We hypothesized that macrophage TBK1 contributes to both IFN and non-IFN components of host defense and IAV pathology. We generated myeloid-conditional TBK1 knockout mice and assessed the in vitro and in vivo consequences of IAV infection. Myeloid-specific loss of TBK1 in vivo resulted in less severe host response to IAV, as assessed by decreased mortality, weight loss, and hypoxia and less inflammatory changes in BALF relative to wildtype (WT) mice despite no differences in viral load. Mice lacking myeloid TBK1 showed less recruitment of CD64+SiglecF-Ly6Chi inflammatory macrophages (InfMs), less expression of inflammatory cytokines in the BALF, and less expression of both interferon regulatory factor (IRF) and NF-kappaB target genes in the lung. Analysis of sorted AMs, InfMs, and lung interstitial macrophages (IMs) revealed that each subpopulation requires TBK1 for distinct components of the response to IAV infection. Our findings define roles for myeloid TBK1 in IAV induced lung inflammation apart from IFN type I expression and point to myeloid TBK1 as a central and cell type-specific regulator of virus-induced lung damage.

PMID- 30290126 TI - Design of the LifeArc Index Set and Retrospective Review of Its Performance: A Collection for Sharing. AB - Building, curating, and maintaining a compound collection is an expensive operation, beyond the scope of most academic organizations. Here we describe the selection criteria used to compile the LifeArc diversity set from commercial suppliers and the process we undertook to generate our representative LifeArc index set. The aim was to avoid a "junk in, junk out" screen collection to increase chemical tractability going forward, while maximizing diversity. Using historical LifeArc screening data, we demonstrate that the index set was predictive of ligandability and that progressable hits could be identified by mining associated clusters within our larger diversity set. Indeed, a higher percentage of index-derived hit clusters were found to have been progressed into hit-to-lead programs, reflecting better drug-likeness. In practice, the library has been shared widely with academic groups and used routinely within LifeArc to assess the ligandability of novel targets. Its small size is well suited to meet the needs of medium-throughput screening in labs with either limited automation, limited precious or expensive reagents, or complex cellular assays. The strategy of screening a small set in combination with rapid hit analog follow-up has demonstrated the utility of finding active clusters for potential development against challenging targets. PMID- 30290128 TI - High-Throughput DNA Plasmid Transfection Using Acoustic Droplet Ejection Technology. AB - The Labcyte Echo acoustic liquid handler allows accurate droplet ejection at high speed from a source well plate to a destination plate. It has already been used in various miniaturized biological assays, such as quantitative PCR (q-PCR), quantitative real-time PCR (q-RT-PCR), protein crystallization, drug screening, cell dispensing, and siRNA transfection. However, no plasmid DNA transfection assay has been published so far using this dispensing technology. In this study, we evaluated the ability of the Echo 550 device to perform plasmid DNA transfection in 384-well plates. Due to the high throughput of this device, we simultaneously optimized the three main parameters of a transfection process: dilution of the transfection reagent, DNA amount, and starting DNA concentration. We defined a four-step protocol whose optimal settings allowed us to transfect HeLa cells with up to 90% efficiency and reach a co-expression of nearly 100% within transfected cells in co-transfection experiments. This fast, reliable, and automated protocol opens new ways to easily and rapidly identify optimal transfection settings for a given cell type. Furthermore, it permits easy software-based transfection control and multiplexing of plasmids distributed on wells of a source plate. This new development could lead to new array applications, such as human ORFeome protein expression or CRISPR-Cas9-based gene function validation in nonpooled screening strategies. PMID- 30290127 TI - Structural and Functional Lung Impairment in Primary Ciliary Dyskinesia. Assessment with Magnetic Resonance Imaging and Multiple Breath Washout in Comparison to Spirometry. AB - RATIONALE: Primary ciliary dyskinesia (PCD) is an inherited disorder characterized by heterogeneous airway disease. Traditional lung function techniques (e.g., spirometry) may underestimate severity and complexity of PCD. OBJECTIVES: We assessed lung impairment in individuals with PCD using structural and functional magnetic resonance imaging (MRI) and different lung function techniques. METHODS: A total of 30 study participants with PCD (median, 13.4 yr; range, 5-28 yr) underwent structural and functional MRI, spirometry, and multiple breath washout (MBW) on the same day. Primary endpoints included structural MRI morphology scores, relative ventilation, and perfusion impairment from functional MRI, forced expiratory volume in 1 second (FEV1) from spirometry, and lung clearance index (LCI) from MBW. RESULTS: Severity and complexity of PCD lung disease varied significantly between individuals. Structural lung disease was detected in all subjects with a median (interquartile range) extent score of 10.3 (7-19; maximum score = 60). Functional MRI ventilation impairment was present in 52% of subjects, affecting 24.2% (21.1 to 25.2%) of the lung. Relative perfusion impairment was detected in 78% of individuals affecting 21.1% (19.4 to 25.9%) of the lung. LCI was abnormal in 83% (median, 8.3 [2.6 to 13.2] z-scores) and FEV1 was abnormal in 27% (-0.5 [-1.6 to 0.3] z-scores) of individuals. Concordance between spirometry and imaging outcomes was poor, with 52% of patients showing both abnormal MRI and LCI values, but normal FEV1. CONCLUSIONS: Discordance between lung function and imaging outcomes in patients with PCD supports the use of both imaging and lung function, such as MBW, for surveillance of this heterogeneous disease.

AB - The goal of nonrestorative or non- and microinvasive caries treatment (fluoride- and nonfluoride-based interventions) is to manage the caries disease process at a lesion level and minimize the loss of sound tooth structure. The purpose of this systematic review and network meta-analysis was to summarize the available evidence on nonrestorative treatments for the outcomes of 1) arrest or reversal of noncavitated and cavitated carious lesions on primary and permanent teeth and 2) adverse events. We included parallel and split-mouth randomized controlled trials where patients were followed for any length of time. Studies were identified with MEDLINE and Embase via Ovid, Cochrane CENTRAL, and Cochrane Database of Systematic Reviews. Pairs of reviewers independently conducted the selection of studies, data extraction, risk-of-bias assessments, and assessment of the certainty in the evidence with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Data were synthesized with a random effects model and a frequentist approach. Forty-four trials (48 reports) were eligible, which included 7,378 participants and assessed the effect of 22 interventions in arresting or reversing noncavitated or cavitated carious lesions. Four network meta-analyses suggested that sealants + 5% sodium fluoride (NaF) varnish, resin infiltration + 5% NaF varnish, and 5,000-ppm F (1.1% NaF) toothpaste or gel were the most effective for arresting or reversing noncavitated occlusal, approximal, and noncavitated and cavitated root carious lesions on primary and/or permanent teeth, respectively (low- to moderate-certainty evidence). Study-level data indicated that 5% NaF varnish was the most effective for arresting or reversing noncavitated facial/lingual carious lesions (low certainty) and that 38% silver diamine fluoride solution applied biannually was the most effective for arresting advanced cavitated carious lesions on any coronal surface (moderate to high certainty). Preventing the onset of caries is the ultimate goal of a caries management plan. However, if the disease is present, there is a variety of effective interventions to treat carious lesions nonrestoratively. PMID- 30290131 TI - Caring for Critically Ill Patients in Humanitarian Settings. AB - Critical care medicine is far from the first medical field to come to mind when humanitarian action is mentioned, yet both critical care and humanitarian action share a fundamental purpose to save lives and ease suffering of people caught in acute crises. Critically ill children and adults will be present regardless of resources limitations, irrespective of geography, regional/cultural contexts, insecurity or socioeconomic status and they may be even more prevalent in a humanitarian crisis. Critical care is not limited to the walls of a hospital and all hospitals will have critically ill patients regardless of designating a specific ward an Intensive Care Unit. Regular and consistent consideration of critical care principles in humanitarian settings provides crucial guidance to Intensivists and non-Intensivists alike. A multi-disciplinary, systematic approach to patient care that encourages critical thinking, checklists which encourage communication amongst team members, and context-specific critical care rapid response teams are examples of critical care constructs that can provide high quality critical care in all environments. Promoting critical care principles conveys the message that critical care is an integral part of healthcare and should be accessible to all, no matter the setting. These principles can be effectively adopted in humanitarian settings by normalizing them to everyday clinical practice. Equally, core humanitarian principles - dignity, accountability, impartiality, neutrality - can be applied to critical care. Applying principles of critical care in a context-specific manner and applying humanitarian principles to critical care can improve the quality of patient care and transcend barriers to resource limitations. PMID- 30290132 TI - Ezrin, a Membrane Cytoskeleton Cross Linker Protein, as a Marker of Epithelial Damage in Asthma. AB - RATIONALE: Bronchial epithelial cell damage occurs in patients with bronchial asthma. Ezrin, a membrane-cytoskeleton protein, maintains cellular morphology and intercellular adhesion and protects the barrier function of epithelial cells. OBJECTIVES: To study the role of ezrin in bronchial epithelial cells injury and correlate its expression with asthma severity. METHODS: Levels of ezrin were measured in exhaled breath condensate (EBC) and serum in asthma patients and bronchoalveolar lavage fluid (BALF) from a mouse model of asthma by ELISA. The regulation of IL-13 on ezrin protein levels was studied in primary bronchial epithelial cells (PBECs). Ezrin knockdown using shRNA was studied in human bronchial epithelial 16HBE cells. RESULTS: Ezrin levels were decreased in asthmatic EBC (392.7+/-34.99 vs 150.5+/-10.22 pg/ml, p<0.0001) and serum (700.7+/ 55.59 vs 279.2+/-25.83pg/ml, p<0.0001) compared to normal subjects. Levels were much lower in uncontrolled (p<0.001) and partly-controlled patients (p<0.01) compared to well-controlled subjects. EBC and serum ezrin levels correlated with lung function in asthma patients and serum ezrin levels were negatively correlated with serum IL-13 and periostin. IL-13-induced down-regulation of ezrin expression in PBECs was significantly attenuated by the JAK2 (Janus tyrosine kinase 2) inhibitor TG101348. Ezrin knockdown changed 16HBE cell morphology, enlarged intercellular spaces and increased their permeability. Ezrin expression was decreased in the lung tissue and BALF of 'asthmatic' mice and negatively correlated with BALF IL-13 level. CONCLUSIONS: Ezrin down-regulation is associated with IL-13-induced epithelial damage and might be a potential biomarker of asthma control.

PMID- 30290139 TI - A Paradigm Shift in Cancer Immunotherapy: From Enhancement to Normalization. AB - Harnessing an antitumor immune response has been a fundamental strategy in cancer immunotherapy. For over a century, efforts have primarily focused on amplifying immune activation mechanisms that are employed by humans to eliminate invaders such as viruses and bacteria. This "immune enhancement" strategy often results in rare objective responses and frequent immune-related adverse events (irAEs). However, in the last decade, cancer immunotherapies targeting the B7-H1/PD-1 pathway (anti-PD therapy), have achieved higher objective response rates in patients with much fewer irAEs. This more beneficial tumor response-to-toxicity profile stems from distinct mechanisms of action that restore tumor-induced immune deficiency selectively in the tumor microenvironment, here termed "immune normalization," which has led to its FDA approval in more than 10 cancer indications and facilitated its combination with different therapies. In this article, we wish to highlight the principles of immune normalization and learn from it, with the ultimate goal to guide better designs for future cancer immunotherapies.

We use these data to characterize the population genetic structure and to investigate genetic associations with maternal and infectious traits. We show that the present day distribution of alleles is a function of both ancient migration and very recent population movements. We reveal novel phenotype-genotype associations, including several replicated associations with height and BMI, an association between maternal age and EMB, and between twin pregnancy and NRG1. Finally, we identify a unique pattern of circulating viral DNA in plasma with high prevalence of hepatitis B and other clinically relevant maternal infections. A GWAS for viral infections identifies an exceptionally strong association between integrated herpesvirus 6 and MOV10L1, which affects piwi-interacting RNA (piRNA) processing and PIWI protein function. These findings demonstrate the great value and potential of accumulating NIPT data for worldwide medical and genetic analyses.

AB - Neanderthals and modern humans interbred at least twice in the past 100,000 years. While there is evidence that most introgressed DNA segments from Neanderthals to modern humans were removed by purifying selection, less is known about the adaptive nature of introgressed sequences that were retained. We hypothesized that interbreeding between Neanderthals and modern humans led to (1) the exposure of each species to novel viruses and (2) the exchange of adaptive alleles that provided resistance against these viruses. Here, we find that long, frequent-and more likely adaptive-segments of Neanderthal ancestry in modern humans are enriched for proteins that interact with viruses (VIPs). We found that VIPs that interact specifically with RNA viruses were more likely to belong to introgressed segments in modern Europeans. Our results show that retained segments of Neanderthal ancestry can be used to detect ancient epidemics. PMID- 30290144 TI - The Human Transcription Factors.

AB - Antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP) critically contribute to the efficacy of anti-tumor therapeutic antibodies. We report here an unexpected finding that macrophages after ADCP inhibit NK cell-mediated ADCC and T cell-mediated cytotoxicity in breast cancers and lymphomas. Mechanistically, AIM2 is recruited to the phagosomes by FcgammaR signaling following ADCP and activated by sensing the phagocytosed tumor DNAs through the disrupted phagosomal membrane, which subsequently upregulates PD-L1 and IDO and causes immunosuppression. Combined treatment with anti-HER2 antibody and inhibitors of PD-L1 and IDO enhances anti tumor immunity and anti-HER2 therapeutic efficacy in mouse models. Furthermore, neoadjuvant trastuzumab therapy significantly upregulates PD-L1 and IDO in the tumor-associated macrophages (TAMs) of HER2+ breast cancer patients, correlating with poor trastuzumab response. Collectively, our findings unveil a deleterious role of ADCP macrophages in cancer immunosuppression and suggest that therapeutic antibody plus immune checkpoint blockade may provide synergistic effects in cancer treatment.

PMID- 30290147 TI - Transcript Buffering: A Balancing Act between mRNA Synthesis and mRNA Degradation. AB - Transcript buffering involves reciprocal adjustments between overall rates in mRNA synthesis and degradation to maintain similar cellular concentrations of mRNAs. This phenomenon was first discovered in yeast and encompasses coordination between the nuclear and cytoplasmic compartments. Transcript buffering was revealed by novel methods for pulse labeling of RNA to determine in vivo synthesis and degradation rates. In this Perspective, we discuss the current knowledge of transcript buffering. Emphasis is placed on the future challenges to determine the nature and directionality of the buffering signals, the generality of transcript buffering beyond yeast, and the molecular mechanisms responsible for this balancing.

AB - Although recent studies provide evidence for a common genetic basis between complex traits and Mendelian disorders, a thorough quantification of their overlap in a phenotype-specific manner remains elusive. Here, we have quantified the overlap of genes identified through large-scale genome-wide association studies (GWASs) for 62 complex traits and diseases with genes containing mutations known to cause 20 broad categories of Mendelian disorders. We identified a significant enrichment of genes linked to phenotypically matched Mendelian disorders in GWAS gene sets; of the total 1,240 comparisons, a higher proportion of phenotypically matched or related pairs (n = 50 of 92 [54%]) than phenotypically unmatched pairs (n = 27 of 1,148 [2%]) demonstrated significant overlap, confirming a phenotype-specific enrichment pattern. Further, we observed elevated GWAS effect sizes near genes linked to phenotypically matched Mendelian disorders. Finally, we report examples of GWAS variants localized at the transcription start site or physically interacting with the promoters of genes linked to phenotypically matched Mendelian disorders. Our results are consistent with the hypothesis that genes that are disrupted in Mendelian disorders are dysregulated by non-coding variants in complex traits and demonstrate how leveraging findings from related Mendelian disorders and functional genomic datasets can prioritize genes that are putatively dysregulated by local and distal non-coding GWAS variants. PMID- 30290153 TI - Activating Mutations in PAK1, Encoding p21-Activated Kinase 1, Cause a Neurodevelopmental Disorder. AB - p21-activated kinases (PAKs) are serine/threonine protein kinases acting as effectors of CDC42 and RAC, which are members of the RHO family of small GTPases. PAK1's kinase activity is autoinhibited by homodimerization, whereas CDC42 or RAC1 binding causes PAK1 activation by dimer dissociation. Major functions of the PAKs include actin cytoskeleton reorganization, for example regulation of the cellular protruding activity during cell spreading. We report the de novo PAK1 mutations c.392A>G (p.Tyr131Cys) and c.1286A>G (p.Tyr429Cys) in two unrelated subjects with developmental delay, secondary macrocephaly, seizures, and ataxic gait. We identified enhanced phosphorylation of the PAK1 targets JNK and AKT in fibroblasts of one subject and of c-JUN in those of both subjects compared with control subjects. In fibroblasts of the two affected individuals, we observed a trend toward enhanced PAK1 kinase activity. By using co-immunoprecipitation and size-exclusion chromatography, we observed a significantly reduced dimerization for both PAK1 mutants compared with wild-type PAK1. These data demonstrate that the two PAK1 variants function as activating alleles. In a cell spreading assay, subject-derived fibroblasts showed significant enrichment in cells occupied by filopodia. Interestingly, application of the PAK1 inhibitor FRAX486 completely reversed this cellular phenotype. Together, our data reveal that dominantly acting, gain-of-function PAK1 mutations cause a neurodevelopmental phenotype with increased head circumference, possibly by a combined effect of defective homodimerization and enhanced kinase activity of PAK1. This condition, along with the developmental disorders associated with RAC1 and CDC42 missense mutations, highlight the importance of RHO GTPase members and effectors in neuronal development. PMID- 30290151 TI - A Recurrent De Novo Heterozygous COG4 Substitution Leads to Saul-Wilson Syndrome, Disrupted Vesicular Trafficking, and Altered Proteoglycan Glycosylation. AB - The conserved oligomeric Golgi (COG) complex is involved in intracellular vesicular transport, and is composed of eight subunits distributed in two lobes, lobe A (COG1-4) and lobe B (COG5-8). We describe fourteen individuals with Saul Wilson syndrome, a rare form of primordial dwarfism with characteristic facial and radiographic features. All affected subjects harbored heterozygous de novo variants in COG4, giving rise to the same recurrent amino acid substitution (p.Gly516Arg). Affected individuals' fibroblasts, whose COG4 mRNA and protein were not decreased, exhibited delayed anterograde vesicular trafficking from the ER to the Golgi and accelerated retrograde vesicular recycling from the Golgi to the ER. This altered steady-state equilibrium led to a decrease in Golgi volume, as well as morphologic abnormalities with collapse of the Golgi stacks. Despite these abnormalities of the Golgi apparatus, protein glycosylation in sera and fibroblasts from affected subjects was not notably altered, but decorin, a proteoglycan secreted into the extracellular matrix, showed altered Golgi dependent glycosylation. In summary, we define a specific heterozygous COG4 substitution as the molecular basis of Saul-Wilson syndrome, a rare skeletal dysplasia distinct from biallelic COG4-CDG. PMID- 30290152 TI - Bi-allelic Loss-of-Function Variants in DNMBP Cause Infantile Cataracts. AB - Infantile and childhood-onset cataracts form a heterogeneous group of disorders; among the many genetic causes, numerous pathogenic variants in additional genes associated with autosomal-recessive infantile cataracts remain to be discovered. We identified three consanguineous families affected by bilateral infantile cataracts. Using exome sequencing, we found homozygous loss-of-function variants in DNMBP: nonsense variant c.811C>T (p.Arg271*) in large family F385 (nine affected individuals; LOD score = 5.18 at theta = 0), frameshift deletion c.2947_2948del (p.Asp983*) in family F372 (two affected individuals), and frameshift variant c.2852_2855del (p.Thr951Metfs*41) in family F3 (one affected individual). The phenotypes of all affected individuals include infantile-onset cataracts. RNAi-mediated knockdown of the Drosophila ortholog still life (sif), enriched in lens-secreting cells, affects the development of these cells as well as the localization of E-cadherin, alters the distribution of septate junctions in adjacent cone cells, and leads to a ~50% reduction in electroretinography amplitudes in young flies. DNMBP regulates the shape of tight junctions, which correspond to the septate junctions in invertebrates, as well as the assembly pattern of E-cadherin in human epithelial cells. E-cadherin has an important role in lens vesicle separation and lens epithelial cell survival in humans. We therefore conclude that DNMBP loss-of-function variants cause infantile-onset cataracts in humans.

PMID- 30290156 TI - A Computational model of the mammalian external tufted cell. AB - We introduce a novel detailed conductance-based model of the bursting activity in external tufted (ET) cells of the olfactory bulb. We investigate the mechanisms underlying their bursting, and make experimentally-testable predictions. The ionic currents included in the model are specific to ET cells, and their kinetic and other parameters are based on experimental recordings. We validate the model by showing that its bursting characteristics under various conditions (e.g. blocking various currents) are consistent with experimental observations. Further, we identify the bifurcation structure and dynamics that explain bursting behavior. This analysis allows us to make predictions of the response of the cell to current pulses at different burst phases. We find that depolarizing (but not hyperpolarizing) inputs received during the interburst interval can advance burst timing, creating the substrate for synchronization by excitatory connections. It has been hypothesized that such synchronization among the ET cells within one glomerulus might help coordinate the glomerular output. Next we investigate model parameter sensitivity and identify parameters that play the most prominent role in controlling each burst characteristic, such as the burst frequency and duration. Finally, the response of the cell to periodic inputs is examined, reflecting the sniffing-modulated input that these cell receive in vivo. We find that individual cells can be better entrained by inputs with higher, rather than lower, frequencies than the intrinsic bursting frequency of the cell. Nevertheless, a heterogeneous population of ET cells (as may be found in a glomerulus) is able to produce reliable periodic population responses even at lower input frequencies. PMID- 30290157 TI - Long non-coding RNA HOXD-AS1 in cancer. AB - Cancer is one of the leading causes of death worldwide with a high risk of incidence and mortality. Long non-coding RNAs (lncRNAs) have been shown to participate in various biological processes, including tumorigenesis and progression. The HOXD-AS1 (also known as HAGLR and Mdgt) gene is located between the HOXD1 and HOXD3 genes in the HOXD cluster and has been reported to play a critical role in the development and progression of cancers. This review summarizes the current knowledge on the biological functions and mechanisms of HOXD-AS1 in different human cancers, including bladder, cervical, colorectal, gastric, ovarian, and prostate cancers, glioma, hepatocellular carcinoma, melanoma, osteosarcoma, and non-small cell lung cancer. The aberrant expression of HOXD-AS1 in these cancers was related with clinical features of patients with cancers. HOXD-AS1 regulates the growth, invasion, and migration of tumor cells through different underlying mechanisms. In conclusion, HOXD-AS1 may be considered as a promising diagnostic/prognostic biomarker or a novel therapeutic target for cancers. PMID- 30290154 TI - Mutations in KCNK4 that Affect Gating Cause a Recognizable Neurodevelopmental Syndrome. AB - Aberrant activation or inhibition of potassium (K+) currents across the plasma membrane of cells has been causally linked to altered neurotransmission, cardiac arrhythmias, endocrine dysfunction, and (more rarely) perturbed developmental processes. The K+ channel subfamily K member 4 (KCNK4), also known as TRAAK (TWIK related arachidonic acid-stimulated K+ channel), belongs to the mechano-gated ion channels of the TRAAK/TREK subfamily of two-pore-domain (K2P) K+ channels. While K2P channels are well known to contribute to the resting membrane potential and cellular excitability, their involvement in pathophysiological processes remains largely uncharacterized. We report that de novo missense mutations in KCNK4 cause a recognizable syndrome with a distinctive facial gestalt, for which we propose the acronym FHEIG (facial dysmorphism, hypertrichosis, epilepsy, intellectual disability/developmental delay, and gingival overgrowth). Patch-clamp analyses documented a significant gain of function of the identified KCNK4 channel mutants basally and impaired sensitivity to mechanical stimulation and arachidonic acid. Co-expression experiments indicated a dominant behavior of the disease-causing mutations. Molecular dynamics simulations consistently indicated that mutations favor sealing of the lateral intramembrane fenestration that has been proposed to negatively control K+ flow by allowing lipid access to the central cavity of the channel. Overall, our findings illustrate the pleiotropic effect of dysregulated KCNK4 function and provide support to the hypothesis of a gating mechanism based on the lateral fenestrations of K2P channels. PMID- 30290158 TI - Discovery of the Long Interspersed Nuclear Element-1 activation product [Open Reading Frame-1 (ORF1) protein] in human blood. AB - Long Interspersed Nuclear Element 1 is the only autonomous mobile DNA capable of self-propagation, and is an environmental biomarker that is activated upon an environmental trigger. We have developed an ELISA method to detect and measure Open Reading Frame-1 (ORF1) and have applied it to interrogate serum samples from men with equivocal prostate specific antigen (PSA) results. Polyclonal antibodies were developed using the first 14-amino acid peptide of N-terminal-ORF1 protein. Remnant serum samples from a total of 53 men, ages>50 yr, were analyzed for immunoreactive ORF1 (iORF1) and PSA concentrations; outcomes for the non-biopsied and biopsied groups were also recorded. The dynamic range of the ELISA was between (CV): 2.0 (14%) to 30 ng/mL (1.2%). The total imprecision (within run/inter-day) was: QC3 = 2.7%/21%, QC6 = 1.1%/18%, and QC20 = 0.33%/11%. The median iORF1 concentration in the non-biopsy group was 14.7 ng/mL (Q1 - Q3: 10.5 Q3:18.4), which was significantly lower than the Biopsy group at 25.0 ng/mL (Q1 Q3: 20.0-33.1), P-value = .003. In conclusion, we have developed a competitive ELISA and discovered the presence of iORF1 in serum, which could be used to advance future studies involving ORF1 measurement from blood. In addition, iORF1 may be a complement with the PSA screen to better detect prostate cancer. PMID- 30290159 TI - Rapamycin induces the expression of heme oxygenase-1 and peroxyredoxin-1 in normal hepatocytes but not in tumorigenic liver cells. AB - Rapamycin (sirolimus) is employed as an immunosuppressant following liver transplant, to inhibit the re-growth of cancer cells following liver resection for hepatocellular carcinoma (HCC), and for the treatment of advanced HCC. Rapamycin also induces the expression of antioxidant enzymes in the liver, suggesting that pretreatment with the drug could provide a potential strategy to reduce ischemia reperfusion injury following liver surgery. The aim of this study was to further investigate the actions of rapamycin in inducing expression of the antioxidant enzymes heme oxygenase-1 (HO-1) and peroxiredoxin-1 (Prx-1) in normal liver and in tumorigenic liver cells. A rat model of segmental hepatic ischemia and reperfusion, cultured freshly-isolated rat hepatocytes, and tumorigenic H4IIE rat liver cells in culture were employed. Expression of HO-1 and Prx-1 was measured using quantitative PCR and western blot. Rapamycin pre-treatment of normal liver in vivo or normal hepatocytes in vitro led to a substantial induction of mRNA encoding HO-1 and Prx-1. The dose-response curve for the action of rapamycin on mRNA expression was biphasic, showing an increase in expression at 0 - 0.1 MUM rapamycin but a decrease from maximum at concentrations greater than 0.1 MUM. By contrast, in H4IIE cells, rapamycin inhibited the expression of HO-1 and Prx-1 mRNA. Oltipraz, an established activator of transcription factor Nrf2, caused a large induction of HO-1 and Prx-1 mRNA. The dose response curve for the inhibition by rapamycin of HO-1 and Prx-4 mRNA expression, determined in the presence of oltipraz, was monophasic with half maximal inhibition at about 0.01 MUM. It is concluded that, at concentrations comparable to those used clinically, pre-treatment of the liver with rapamycin induces the expression of HO-1 and Prx-1. However, the actions of rapamycin on the expression of these two antioxidant enzymes in normal hepatocytes are complex and, in tumorigenic liver cells, differ from those in normal hepatocytes. Further studies are warranted to evaluate preconditioning the livers of patients subject to liver resection or liver transplant with rapamycin as a viable strategy to reduce IR injury following liver surgery. PMID- 30290160 TI - Inhibition of catechol-O-methyltransferase in the cynomolgus monkey by opicapone after acute and repeated administration. AB - INTRODUCTION: The aim of the study was to clarify the dose response for inhibition of catechol-O-methyltransferase (COMT) by opicapone, a third generation COMT inhibitor, after acute and repeated administration to the cynomolgus monkey with pharmacokinetic evaluation at the higher dose. METHODS: Three cynomolgus monkeys were used in the study. In the first experiment, COMT inhibition was evaluated over 24 h after the first and at 24 h after the last of 14 daily oral administrations of vehicle, 1, 10 and 100 mg/kg opicapone using a crossover design. In the second experiment, the effect of the maximally effective dose, 100 mg/kg, was retested under the same conditions with additional monitoring of plasma opicapone levels to explore the relationship between pharmacokinetics and pharmacodynamics. RESULTS: Opicapone dose-dependently inhibited COMT activity, significantly so at 10 and 100 mg/kg. Maximal inhibition was 13.1%, 76.4% and 93.2% at 1, 10 and 100 mg/kg respectively, and COMT remained significantly inhibited at 24 h after 10 and 100 mg/kg (42.6% and 60.2% respectively). Following repeated administration of opicapone residual COMT inhibition at 24 h was 15-25% greater at all doses. In contrast to its pharmacodynamic effect, opicapone was rapidly absorbed and eliminated, with no accumulation in plasma following repeated administration. CONCLUSION: Opicapone showed sustained and dose-dependent COMT inhibition despite being rapidly eliminated from plasma and with no evidence for accumulation in plasma after 14 days administration. Opicapone fills the unmet need for a compound with sustained COMT inhibition which will improve levodopa bioavailability in patients with Parkinson's disease.

AB - Geroprotectors, a class of drugs targeting multiple deficits occurring with age, necessitate the development of new animal models to test their efficacy. The COST Action MouseAGE is a European network whose aim is to reach consensus on the translational path required for geroprotectors, interventions targeting the biology of ageing. In our previous work we identified frailty and loss of resilience as a potential target for geroprotectors. Frailty is the result of an accumulation of deficits, which occurs with age and reduces the ability to respond to adverse events (physical resilience). Modelling frailty and physical resilience in mice is challenging for many reasons. There is no consensus on the precise definition of frailty and resilience in patients or on how best to measure it. This makes it difficult to evaluate available mouse models. In addition, the characterization of those models is poor. Here we review potential models of physical resilience, focusing on those where there is some evidence that the administration of acute stressors requires integrative responses involving multiple tissues and where aged mice showed a delayed recovery or a worse outcome then young mice in response to the stressor. These models include sepsis, trauma, drug- and radiation exposure, kidney and brain ischemia, exposure to noise, heat and cold shock. PMID- 30290162 TI - The expression of sex steroid receptors and sex steroid-synthesizing/metabolizing enzymes in metastasized lymph nodes of prostate Cancer. AB - The status of sex steroid receptors and sex steroid-metabolizing enzymes has been reported in primary prostate cancer lesions, but that in metastatic lymph nodes has remained unknown. Therefore, in this study, we immunolocalized these proteins in primary tumors and paired metastatic lymph nodes of prostate cancer and correlated the findings with clinicopathologic factors of individual patients. The expression status of androgen receptor (AR) and estrogen receptor beta (ERbeta) was significantly increased in metastatic lymph nodes compared to primary lesions, while that of 17betaHSD1, 17betaHSD2, 17betaHSD5 and STS immunoreactivity was decreased in metastatic lymph nodes. In metastatic lymph nodes, the status of 5alpha2 was significantly correlated with that of AR. In addition, 17betaHSD5, 5alpha1, STS and EST positive cases were significantly associated with Gleason score status (GS) (GS>8 vs GS<7) in metastatic lymph nodes. Results of our present study did demonstrate that in situ androgen and estrogen metabolism and action play roles in pathophysiology of prostate cancer in metastatic lymph nodes, but these steroidogenic effects could be different from those in primary lesion. PMID- 30290163 TI - Ocular surface and chronic pesticide exposure: Evaluating the alterations in corneal cellular turnover concerning cell cycle and apoptosis. AB - The consequences of chronic pesticide exposure on the ocular surface are not yet fully known and lacunae exist regarding the repercussions of this xenobiotic insult on cellular turnover. The present work aims to establish the mechanistic relationship between ocular morbidity and chronic pesticide exposure by analyzing the impact on key regulators responsible for cell cycle and death. Vital components of cell cycle and death were primarily explored in this study by mimicking the on-field scenario regarding chronic pesticide exposure in a murine model. Various cellular aspects were taken into consideration through culture analyses, flowcytometric evaluation, fluorescence microscopic studies etc. We observed downregulation of key players of the cell-cycle at different stages (viz. Cyclin-D1, CDK4, pRb, PCNA, PP1, PP2A, p-cdc 25c and Aurora kinase A) with a corresponding increase in the expression of cell-cycle inhibitors like p18 and p21, which lead to hypoproliferation of corneal epithelial cells post pesticide exposure. The expression of GSK 3beta, a master-molecule involved in both cell cycle and apoptotic pathways corresponded well with the scientific theme and indicated towards cellular hypoproliferation and increase of apoptosis. Key players of both the intrinsic (viz. Bax/Bcl2, JNK) and extrinsic (viz. CD 95) apoptotic pathways were found to be activated leading to enhanced cleaved Caspase 3 expression and corresponding cell death. We tried to highlight the mechanistic correlation between the alterations in cellular turnover as the reason behind the heightened ocular morbidity due to 'chronic pesticide exposure'- the xenobiotic stress exerted by these 'farmers' friends'. PMID- 30290164 TI - ERK1/2-mediated EGFR-signaling is required for TGFbeta-induced lens epithelial mesenchymal transition. AB - Epithelial-mesenchymal transition (EMT) of lens epithelial cells (LECs) plays a critical role in the pathogenesis of fibrotic cataract. Transforming growth factor-beta (TGFbeta) is a potent inducer of this fibrotic process in lens. Recent studies in cancer progression have shown that in addition to activating the canonical Smad signaling pathway, TGFbeta can also transactivate the epidermal growth factor receptor (EGFR) to enhance invasive cell migration. The present study aims to elucidate the involvement of EGFR-signaling in TGFbeta induced EMT in LECs. Treatment with TGFbeta2 induced transdifferentiation of LECs into myofibroblastic cells, typical of an EMT. TGFbeta2 induced the phosphorylation of the EGFR and upregulation of Egfr and Hb-egf gene expression. Pharmacologic inhibition of EGFR-signaling using PD153035 inhibited TGFbeta induced EMT, including the upregulation of mesenchymal markers and downregulation of epithelial markers. Crosstalk between TGFbeta2-induced EGFR and ERK1/2 was evident, with both pathways impacting on Smad2/3-signaling. Our finding that TGFbeta2 transactivates downstream EGFR-signaling reveals a previously unknown mechanism in the pathogenesis of cataract. Understanding the complex interplay between divergent canonical and non-canonical signaling pathways, as well as downstream target genes involved in TGFbeta-induced EMT, will enable the development of more effective targeted therapies in the pharmacological treatment of cataract. PMID- 30290165 TI - Spred negatively regulates lens growth by modulating epithelial cell proliferation and fiber differentiation. AB - Spred, like Sprouty (Spry) and also Sef proteins, have been identified as important regulators of receptor tyrosine kinase (RTK)-mediated MAPK/ERK signaling in various developmental systems, controlling cellular processes such as proliferation, migration and differentiation. Spreds are widely expressed during early embryogenesis, and in the eye lens, become more localised in the lens epithelium with later development, overlapping with other antagonists including Spry. Given the synexpression of Spreds and Spry in lens, in order to gain a better understanding of their specific roles in regulating growth factor mediated-signaling and cell behavior, we established and characterised lines of transgenic mice overexpressing Spred1 or Spred2, specifically in the lens. This overexpression of Spreds resulted in a small lens phenotype during ocular morphogenesis, retarding its growth by compromising epithelial cell proliferation and fiber differentiation. These in situ findings were shown to be dependent on the ability of Spreds to suppress MAPK-signaling, in particular FGF-induced ERK1/2-signaling in lens cells. This was validated in vitro using lens epithelial explants, that highlighted the overlapping role of Spreds with Spry2, but not Spry1. This study provides insights into the putative function of Spreds and Spry in situ, some overlapping and some distinct, and their importance in regulating lens cell proliferation and fiber differentiation contributing to lens and eye growth. PMID- 30290166 TI - Deoxynivalenol induces toxicity and apoptosis in piglet hippocampal nerve cells via the MAPK signaling pathway. AB - Deoxynivalenol (DON) is a mycotoxin capable of producing a variety of toxic effects in human and animals. In this study, the effect of DON treatment on cytotoxicity and apoptotic pathways in piglet hippocampal nerve cells (PHNCs) was determined. The effects of DON on cellular morphology, cell activity, lactate dehydrogenase (LDH) release, the protein expression of mitogen-activated protein kinase (MAPK) pathway, and the relative expression of key genes related to apoptosis were evaluated. The results indicated that DON significantly inhibited cellular viability and promoted the release of LDH by damaging the membrane integrity of PHNCs, however, the cellular viability was increased and LDH leakage rate were decreased after adding MAPK inhibitors. DON induced PHNCs apoptosis and phosphorylation of MAPK pathway proteins dose-dependently. The ratios of phospho p-JNK/JNK and p-p38/p38 significantly increased with the increase of DON concentration, while the p-ERK/ERK ratio significantly decreased. In addition, DON upregulated the BAX mRNA level, and downregulated the BCL2 mRNA level. Pre incubation with inhibitors of JNK (SP600125) and p38 (SB202190) significantly decreases the BAX/BCL2 ratio. However, pre-incubation with the inhibitor of ERK (U0126), significantly increased the BAX/BCL2 ratio. These data demonstrated that DON induces toxic effects and apoptosis in PHNCs via the MAPK signaling pathway. PMID- 30290167 TI - Inducible SHP-2 activation confers resistance to imatinib in drug-tolerant chronic myeloid leukemia cells. AB - BCR-ABL kinase mutations, accounting for clinical resistance to tyrosine kinase inhibitor (TKI) such as imatinib, frequently occur in acquired resistance or in advanced phases of chronic myeloid leukemia (CML). Emerging evidence implicates a critical role for non-mutational drug resistance mechanisms underlying the survival of residual cancer 'persister' cells. Here, we utilized non-mutational imatinib-resistant K562/G cells to reveal SHP-2 as a resistance modulator of imatinib treatment response during the early phase. SHP-2 phosphorylation was significantly higher in K562/G cells than in sensitive K562 cells. In K562 cells, both short-term and long-term exposure to imatinib induced SHP-2 phosphorylation. Consistently, gain- and loss-of-function mutants in SHP-2 proved its regulation of imatinib resistance. SHP-2 inhibitor and imatinib exhibited a strong antitumor synergy in in vitro and in vivo K562/G models. Mechanistically, dual SHP-2 and BCR-ABL inhibition blocked RAF/MEK/ERK and PI3K/AKT/mTOR pathways, respectively, leading to dramatic apoptotic death of K562/G cells. In conclusion, our results highlight that SHP-2 could be exploited as a biomarker and therapeutic target during the early phase of imatinib resistance development in CML. PMID- 30290168 TI - Metformin attenuates cardiovascular and renal injury in uninephrectomized rats on DOCA-salt: Involvement of AMPK and miRNAs in cardioprotection. AB - Hypertension is associated with major cardiovascular (CV) and renal complications. The molecular intricacy by which hypertension leads to end organ damage is not known. To address this, we aimed to determine the effect of deoxycorticosterone acetate (DOCA) -salt (sodium chloride)-induced hypertension on the alterations in renin-angiotensin system, leading to CV and renal dysfunction in uninephrectomized male Sprague Dawley rats. MicroRNAs involved in this were also not yet explored. Metformin was used to delineate the role of AMPK in mitigating the hypertension-induced CV and renal dysfunction. Administering DOCA and offering saline to uninephrectomized rats, induced hypertension and associated abnormalities of diastolic dysfunction, CV and renal hypertrophy and fibrosis via activating local renin angiotensin system. Western blotting and RT qPCR analysis of diseased heart revealed decreased SERCA2, p-AMPK, miR-146a, miR 99b and increased miR-155 and metformin administered, at dose of 300 mg/kg/day, for a period of 8 weeks prevented CV and renal damage. To our knowledge, we are the first to show that involvement of epigenetic alterations at microRNA level might be responsible for hypertension-induced cardiac dysfunction and metformin reverses these alterations. PMID- 30290169 TI - Salinomycin ameliorates oxidative hepatic damage through AMP-activated protein kinase, facilitating autophagy. AB - Salinomycin, a monocarboxylic ionophore in Streptomyces albus, has been studied as an anti-cancer agent. However, we wondered whether salinomycin has another effect such as an anti-oxidant and hepatic protectant, because some chemical drugs treating human diseases were sometimes related with their toxic effects. Therefore, this study was conducted to examine the effects of salinomycin against oxidative stress and mitochondrial impairment in vivo and in vitro as well as the cellular mechanisms of action. In hepatocyte, salinomycin inhibited arachidonic acid (AA) + iron-induced apoptosis, mitochondrial dysfunction and ROS production. As a molecular mechanism, salinomycin induced autophagy through AMP-activated protein kinase (AMPK) activation, as assessed by the accumulation of acidic vesicle organelles, p62 and LC3-II. Moreover, these protective effects were blocked by AMPK inhibition, which indicates the importance of AMPK in the process of salinomycin's effects. In mice, oral administration of salinomycin protected against carbon tetrachloride (CCl4)-induced oxidative stress and liver injury, and also activated AMPK as well as autophagy-related proteins in the liver. Collectively, salinomycin had the ability to protect hepatocytes against AA+iron induced reactive oxygen species production and mitochondrial dysfunction, as well as CCl4-induced liver injury. Although this beneficial effect was demonstrated under severe oxidative stress, this study showed that salinomycin protected the liver against the oxidative stress and liver damage through AMPK and autophagy, and suggest that salinomycin has a possibility to treat a broad range of diseases.

PMID- 30290178 TI - Stage-Specific Transcription Factors Drive Astrogliogenesis by Remodeling Gene Regulatory Landscapes. AB - A broad molecular framework of how neural stem cells are specified toward astrocyte fate during brain development has proven elusive. Here we perform comprehensive and integrated transcriptomic and epigenomic analyses to delineate gene regulatory programs that drive the developmental trajectory from mouse embryonic stem cells to astrocytes. We report molecularly distinct phases of astrogliogenesis that exhibit stage- and lineage-specific transcriptomic and epigenetic signatures with unique primed and active chromatin regions, thereby revealing regulatory elements and transcriptional programs underlying astrocyte generation and maturation. By searching for transcription factors that function at these elements, we identified NFIA and ATF3 as drivers of astrocyte differentiation from neural precursor cells while RUNX2 promotes astrocyte maturation. These transcription factors facilitate stage-specific gene expression programs by switching the chromatin state of their target regulatory elements from primed to active. Altogether, these findings provide integrated insights into the genetic and epigenetic mechanisms steering the trajectory of astrogliogenesis. PMID- 30290177 TI - Muscle Satellite Cell Cross-Talk with a Vascular Niche Maintains Quiescence via VEGF and Notch Signaling. AB - Skeletal muscle is a complex tissue containing tissue resident muscle stem cells (satellite cells) (MuSCs) important for postnatal muscle growth and regeneration. Quantitative analysis of the biological function of MuSCs and the molecular pathways responsible for a potential juxtavascular niche for MuSCs is currently lacking. We utilized fluorescent reporter mice and muscle tissue clearing to investigate the proximity of MuSCs to capillaries in 3 dimensions. We show that MuSCs express abundant VEGFA, which recruits endothelial cells (ECs) in vitro, whereas blocking VEGFA using both a vascular endothelial growth factor (VEGF) inhibitor and MuSC-specific VEGFA gene deletion reduces the proximity of MuSCs to capillaries. Importantly, this proximity to the blood vessels was associated with MuSC self-renewal in which the EC-derived Notch ligand Dll4 induces quiescence in MuSCs. We hypothesize that MuSCs recruit capillary ECs via VEGFA, and in return, ECs maintain MuSC quiescence though Dll4. PMID- 30290180 TI - Modulation of male mouse sociosexual and anxiety-like behaviors by vasopressin receptors. AB - Although the involvement of two types of vasopressin (AVP) receptors, v1a and v1b, in neural regulation of social behavior is well documented in rodents, there is no report on combined actions of them in regulation of social behavior. In this study, we investigated behavioral differences between wild-type (WT) and v1a and v1b double knockout (dKO) mice. For this, we measured olfactory preference, sexual behavior with receptive females (four weekly tests) in an enriched large observation cage, and anxiety-like behaviors. No difference between WT and dKO mice was found in olfactory preferences for estrous female odor to male odor. Over all four mating tests, the number of mounts and pursuits after receptive females was significantly greater in dKO mice than in WT mice. In the elevated plus maze and the open field test, dKO mice showed lower anxiety-like behavior than WT mice. Finally, we measured approach behavior to several types of objects, figurines, and caged anestrous or estrous females placed in the open field apparatus. The only difference observed was that dKO mice spent longer in the vicinity of estrous females than did WT mice. These findings suggest that vasopressin receptors are involved in the regulation of sociosexual behavior, presumably partly mediated by emotional responses, in male mice. PMID- 30290181 TI - Sexually experienced, but not naive, female rats show a conditioned object preference (COP) for mating after a single training trial. AB - Female rats with mating experience spend more time with the male rat, exhibit shorter contact-return latency to intromission, and display more proceptive behaviors in the male rat's compartment than during the first mating experience. The present study tested 1) whether mating induced conditioned object preference (COP) is possible with a single conditioning trial and 2) whether a preference is induced for an object associated with the first mating encounter or the fifth mating encounter in female rats. Ovariectomized, Long-Evans female rats were primed with estradiol benzoate + progesterone and either exposed to an empty paced mating chamber for 15 min (Naive) or received a 15 intromission test of paced mating behavior (Experienced) on four separate occasions before undergoing the COP procedure. Experienced, but not Naive, female rats developed a COP for a single mating bout, indicating that mating is highly rewarding for sexually experienced female rats. The findings raise questions about the effect of sexual experience on reward regions in the brain, the responsiveness of genital tissue, and learning mechanisms. PMID- 30290179 TI - Single-Cell Transcriptomic Analysis of Cardiac Differentiation from Human PSCs Reveals HOPX-Dependent Cardiomyocyte Maturation. AB - Cardiac differentiation of human pluripotent stem cells (hPSCs) requires orchestration of dynamic gene regulatory networks during stepwise fate transitions but often generates immature cell types that do not fully recapitulate properties of their adult counterparts, suggesting incomplete activation of key transcriptional networks. We performed extensive single-cell transcriptomic analyses to map fate choices and gene expression programs during cardiac differentiation of hPSCs and identified strategies to improve in vitro cardiomyocyte differentiation. Utilizing genetic gain- and loss-of-function approaches, we found that hypertrophic signaling is not effectively activated during monolayer-based cardiac differentiation, thereby preventing expression of HOPX and its activation of downstream genes that govern late stages of cardiomyocyte maturation. This study therefore provides a key transcriptional roadmap of in vitro cardiac differentiation at single-cell resolution, revealing fundamental mechanisms underlying heart development and differentiation of hPSC derived cardiomyocytes. PMID- 30290182 TI - Sick and grumpy: Changes in social behaviour after a controlled immune stimulation in group-housed gilts. AB - Poor health is associated with an increased risk of tail biting outbreaks in pigs. We propose that this is because illness changes social dynamics either by changing the behaviour of the sick pig towards its penmates, the behaviour of the healthy penmates towards the sick pig, or both. We tested the effect of immune stimulation (lipopolysaccharide (LPS) injection: O111:B4; 1.5 MUg kg-1 IV) on social behaviour in gilts housed in triplets in a cross-over experiment. Each pen was subjected to the control treatment (all three pigs injected with saline) and then LPS treatment (one pig injected with LPS, two injected with saline), or vice versa. LPS injected pigs had a shift in social motivation and performed more tail and ear- directed behaviour than saline pigs two days after injection. They seemed to fit the description of 'sick and grumpy'. This change was seen about 40 h after the signs of acute illness dissipated and was not accompanied by a similar increase in activity. We discuss possible mechanisms for this behavioural change in light of changes in neurotransmitter levels at three days after LPS injection described in a previous experiment. PMID- 30290183 TI - Cryptochrome 1 promotes osteogenic differentiation of human osteoblastic cells via Wnt/beta-Catenin signaling. AB - AIMS: The exact mechanism underlying osteoblast differentiation and proliferation remains to be further elucidated. The circadian clock has been universally acknowledged controls behavioral activities and biological process in mammals. Cryptochrome 1 (Cry1), one of the core circadian genes, is associated with bone metabolism. However, the exact role and potential mechanism of Cry1 in regulating osteogenesis are still unclear. MAIN METHODS: Western blotting and qRT-PCR were applied to detect Cry1 expression levels, molecules in osteogenesis related signaling pathways and osteogenic transcriptional markers. The ALP staining and Alizarin red S staining were performed to weigh osteogenic state, while CCK8 assay was used to detect cell growth rates. Osteogenic capability of osteoblasts was determined using an ectopic bone formation assay. KEY FINDINGS: Cry1 was upregulated in the process of osteoblast differentiation, along with osteogenic transcriptional factors. Then, Cry1 upregulation and knockdown cell lines were established and we found Cry1 overexpression promoted osteogenesis and proliferation of osteoblasts both in vitro and in vivo. Besides, the canonical Wnt/beta-Catenin signaling was increasingly activated by Cry1 overexpression, whereas inhibition of beta-Catenin restrained enhanced osteogenic capability of Cry1 upregulated osteoblasts. SIGNIFICANCE: In conclusion, these results suggest that Cry1 promotes osteogenic differentiation of human osteoblasts through the canonical Wnt/beta-Catenin signaling. PMID- 30290184 TI - Alternative mechanisms of translation initiation: An emerging dynamic regulator of the proteome in health and disease. AB - Eukaryotic mRNAs were historically thought to rely exclusively on recognition and binding of their 5' cap by initiation factors to effect protein translation. While internal ribosome entry sites (IRESs) are well accepted as necessary for the cap-independent translation of many viral genomes, there is now recognition that eukaryotic mRNAs also undergo non-canonical modes of translation initiation. Recently, high-throughput assays have identified thousands of mammalian transcripts with translation initiation occurring at non-canonical start codons, upstream of and within protein coding regions. In addition to IRES-mediated events, regulatory mechanisms of translation initiation have been described involving alternate 5' cap recognition, mRNA sequence elements, and ribosome selection. These mechanisms ensure translation of specific mRNAs under conditions where cap-dependent translation is shut down and contribute to pathological states including cardiac hypertrophy and cancer. Such global and gene-specific dynamic regulation of translation presents us with an increasing number of novel therapeutic targets. While these newly discovered modes of translation initiation have been largely studied in isolation, it is likely that several act on the same mRNA and exquisite coordination is necessary to maintain 'normal' translation. In this short review, we summarize the current state of knowledge of these alternative mechanisms of eukaryotic protein translation, their contribution to normal and pathological cell biology, and the potential of targeting translation initiation therapeutically in human disease. PMID- 30290185 TI - Application of induced pluripotent stem cell transplants: Autologous or allogeneic? AB - The development of induced pluripotent stem cells (iPS cells) has raised the prospect of patient-specific treatments for various diseases. Theoretically, iPS cell technology avoids the limitations of human embryonic stem cells (ES cells), including poor establishment, ethical issues, and immune rejection of allogeneic transplantation. However, the immunogenicity of iPS cells has attracted the attention of researchers, and it remains unclear whether iPS cells and their derivatives will be recognized as a patient's own cells. Even though iPS-derived functional cells have been used in the treatment of some diseases, the process of somatic cell reprogramming and iPS cell differentiation is time-consuming, making it difficult to use iPS cells in acute illness or injury. In recent years, it has been suggested that iPS cells may be used as allografts by establishing an iPS cell bank and HLA matching, providing a novel strategy for the clinical application of iPS cells. This article provides a concise overview of iPS cell immunogenicity, and summarizes published data regarding the application of iPS cells in both autologous and allogeneic transplantation in order to help develop more reliable biotechnical strategies utilizing iPS cells. PMID- 30290186 TI - Bone health consequence of adjuvant Anastrozole in monotherapy or associated with biochanin-A in ovariectomized rat model. AB - AIMS: We investigate the consequence of adjuvant anastrozole (ANA) in monotherapy or associated with biochanin A (BCA) in ovariectomized (OVX) rat model and the degree of developing bone loss in both conditions. MATERIALS AND METHODS: Sixty female rats were assigned to six groups. Five groups were bilaterally OVX, and one was sham operated. The five groups were; ANA group (0.5 mg/kg b.wt orally), BCA (5 mg/kg b.wt intraperitoneally (I/P), co-treated group (BCA + ANA), two control groups receiving even distilled water orally or DMSO I/P for twenty weeks. Bone turnover biomarkers BALP, OC, PTH, TRAP and TNFalpha were determined in serum. Bone mineral content, histological and morphometric measurements on rat femurs were performed. BMD by X-ray technique on tibias of rats and CT analysis of lumbar vertebrae of all treated and sham groups were applied. KEY FINDINGS: There was marked elevation in bone turnover biomarkers with high serum Ca and P content in the ANA-treated rats. Moreover marked elevation of TNFalpha, PTH, TC and TG, ANA caused severe changes in the BMD detected by X-ray in tibial bones and CT analysis of lumbar vertebrae of OVX rats. While I/P injection of BCA ameliorated the adverse bone health decrements caused by ANA. SIGNIFICANCE: The study highlights the importance of the BCA supplementation in accordance with the ANA therapy in case of ovariectomized rat model of osteoporosis which is clinically presented in Postmenopausal women with breast cancer during which considerable risk of developing osteoporosis is predicted during treatment. PMID- 30290187 TI - Updated review of current pharmacological and non-pharmacological management of irritable bowel syndrome. AB - Irritable bowel syndrome (IBS) is a functional disorder of the gastrointestinal tract that is usually associated with chronic abdominal pain and altered bowel habits. The two spectra of the disease include constipation-predominant IBS and Diarrhea-predominant IBS. Earlier it was thought to be an unexplained brain-gut disorder, but of late, various underlying causes suggesting primary gut disturbance have been identified. The initial management primarily includes the non-pharmacological measures such as dietary modifications, increasing physical activity, and psychological therapy. Pharmacological management is adjunct to non pharmacological management, and the drug is chosen based on the predominant symptom of bowel habit whether constipation or diarrhea. In this review, we aim to update the readers on the currently available management options in the treatment of IBS - both pharmacological and non-pharmacological options. Further, for the various pharmacological treatments, we summarize the clinical pharmacology, indications, contraindications, adverse effects and use in pregnancy. PMID- 30290188 TI - Cannabinoids in depressive disorders. AB - Cannabis sativa is one of the most popular recreational and medicinal plants. Benefits from use of cannabinoid agents in epilepsy, multiple sclerosis, Parkinson's disease, Alzheimer's disease, and others have been suggested. It seems that the endocannabinoid system is also involved in the pathogenesis and treatment of depression, though its role in this mental disease has not been fully understood yet. Both the pro- and antidepressant activity have been reported after cannabis consumption and a number of pre-clinical studies have demonstrated that both agonist and antagonist of the endocannabinoid receptors act similarly to antidepressants. Responses to the cannabinoid agents are relatively fast, and most probably, the noradrenergic, serotoninergic, glutamatergic neurotransmission, neuroprotective activity, as well as modulation of the hypothalamic-pituitary-adrenal axis are implicated in the observed effects. Based on the published data, the endocannabinoid system evidently gives novel ideas and options in the field of antidepressant treatment, however further studies are needed to determine which group of patients could benefit from this type of therapy.

PMID- 30290191 TI - Corticosteroids in the Management of Severe Coccidioidomycosis. AB - BACKGROUND: There is limited data suggesting that recovery from severe pulmonary infection with Coccidioides may be hastened by the addition of systemic corticosteroids. METHODS: We present a case report of 2 patients with persistent and progressive coccidioidomycosis who demonstrated a dramatic response to adjunctive corticosteroid therapy. RESULTS: Both patients had Coccidioides immitis cultured from respiratory samples. One was a 69-year-old man who had been treated with combination fluconazole and liposomal amphotericin for over 6 weeks, with persistent fever and pneumonia. The other was a 61-year-old man treated with fluconazole and then amphotericin for 3 weeks, with progression to acute respiratory distress syndrome and shock. Both received short courses of intravenous methylprednisolone and recovered to be discharged home. CONCLUSIONS: As opposed to associated hypersensitivity, corticosteroid treatment in these cases was directed at modulating the ongoing destructive effects of unchecked inflammation. Rapid improvement was noted in both cases and raises the possibility that the addition of systemic corticosteroids may hasten recovery in patients with severe coccidioidomycosis. PMID- 30290192 TI - Inferior Vena Cava Filters in Patients with Recurrent Pulmonary Embolism. AB - BACKGROUND: There are sparse data to support the recommendation for inferior vena cava (IVC) filters in patients with recurrent pulmonary embolism while on anticoagulant therapy. METHODS: This was a retrospective cohort study of administrative data from the Premier Healthcare Database, 2009-2014. All-cause mortality according to the use of IVC filters was evaluated in patients who suffered a recurrent pulmonary embolism within 3 months of an index pulmonary embolism. Patients were identified by International Classification of Disease, 9th Clinical Modification codes. A time-dependent analysis controlled for immortal time bias. RESULTS: An IVC filter was inserted in 603 of 814 (74.1%) of patients hospitalized for recurrent pulmonary embolism within 3 months of an index pulmonary embolism. Mortality with an IVC filter was 18 of 603 (3.0%) vs 83 of 211 (39.3%) (P < .0001) without a filter. Among patients with recurrent pulmonary embolism who were stable and did not receive thrombolytic therapy or undergo pulmonary embolectomy, mortality with an IVC filter was 15 of 572 (2.6%) vs 72 of 169 (42.6%) (P < .0001) without a filter. CONCLUSION: In the United States, usual practice was to insert an IVC filter in patients with early recurrent pulmonary embolism. Mortality was lower in those who received an IVC filter. Even stable patients with early recurrent pulmonary embolism showed a decreased mortality with IVC filters, even though in other circumstances, IVC filters do not reduce mortality in stable patients. Additional cohort studies would be useful in the absence of a randomized controlled trial. PMID- 30290193 TI - Variation in the Use of Warfarin and Direct Oral Anticoagulants in Atrial Fibrillation and Associated Cost Implications. AB - BACKGROUND: Little is known about national patterns of anticoagulant use among patients with atrial fibrillation after the availability of direct oral anticoagulants (DOACs) and the associated implications for healthcare spending. METHODS: The Medical Expenditure Panel Survey, a nationally representative survey, collects detailed information about prescription drug use, cost, and medical diagnoses. Using International Classification of Disease Ninth Edition (ICD-9) codes and self-reporting, adults with atrial fibrillation were estimated between 2010 and 2014. We examined proportions of patients receiving warfarin and DOACs overall and across sociodemographic and clinical groups. Total drug expenditures and out-of-pocket spending were calculated adjusting to 2014 US dollars. RESULTS: The study population ranged from 364 (equivalent to 4.7 million) in 2010 to 409 (equivalent to 5.5 million) in 2014. Overall use of any anticoagulant increased from 32.4% to 40.1%. DOAC use increased from 0.56% to 17.2%, and warfarin use declined from 32.8% to 22.9% (p trend < 0.01). This trend was seen in nearly all subgroups evaluated. Estimated prescription drug spending on DOACs and warfarin during this time rose from $330 million to $1.9 billion. Out-of-pocket costs for DOACs increased from $10 million to $218 million. CONCLUSION: In a large, nationwide cohort of adults with atrial fibrillation, we observed a rapid increase in the use of DOACs, significant disparities in medication use based on sociodemographic and clinical factors, and an increase in overall and out-of-pocket costs for anticoagulants corresponding to the increased use of DOACs. These patterns have important implications for healthcare quality, equity, and spending. PMID- 30290194 TI - Bacteriophage T7 transcription system: an enabling tool in synthetic biology. AB - Since its discovery in the 1970s, the T7 RNA polymerase (T7 RNAP) transcription system has been applied extensively as an effective tool in molecular biology because of its robust function in various hosts, including prokaryotic, eukaryotic and cell free systems. Recently, the T7 RNAP transcription system has emerged as a critical component for synthetic biology. The present paper summarizes the advances of the T7 RNAP transcription system in synthetic biology, including the recent progress of T7 RNAP structure and its cognate promoter and terminator and its application in cell free systems, logic gates and orthogonal genetic circuits. PMID- 30290195 TI - Biological impacts of organophosphates chlorpyrifos and diazinon on development, mitochondrial bioenergetics, and locomotor activity in zebrafish (Danio rerio). AB - The objectives of this study were to compare the biological responses in developing zebrafish to two organophosphate insecticides, chlorpyrifos (CPF) and diazinon (DZN). Zebrafish embryos were exposed to either solvent control (0.1% DMSO, v/v), or one dose of 0.1, 1.0, 10.0 and 25.0 MUM CPF, as well as one dose of 0.1, 1.0, 10.0 and 100.0 MUM DZN for 96 h. CPF at 10.0 and 25.0 MUM caused 70 80% and 100% mortality in embryos after 96 h exposure, whereas embryos treated with 10.0 and 100.0 MUM DZN showed 30-40% and 70-80% lethality. CPF at 10.0 MUM significantly decreased cumulative hatching rate, whereas hatching rate was significantly reduced in embryos treated with 100.0 MUM DZN. Spinal lordosis was primarily observed in larvae exposed to 1.0 and 10.0 MUM CPF, whereas pericardial edema was mainly detected with 10.0 and 100.0 MUM DZN exposure. Embryo exposed to 1.0, 10.0 and 25.0 MUM CPF exhibited no mitochondrial dysfunction; exposure to 100.0 MUM DZN significantly inhibited mitochondrial bioenergetics. To determine if CPF and DZN affected larval activity, dark photokinesis response was assessed in larvae following 7 days exposure to 0.1 and 1.0 MUM CPF, as well as to 0.1 1.0, and 10.0 MUM DZN. Larvae exposed to 1.0 MUM CPF showed hypoactivity, whereas the activity in the dark was not overtly changed in larvae exposed to DZN. In summary, CPF showed higher developmental toxicity compared to DZN. Moreover, based on the types of morphological deformities noted, as well as differences in locomotor activity, we conclude that OPs have unique chemical-specific modes of action that can result in varied biological responses during early development. PMID- 30290196 TI - Nasal immunization with RSV F and G protein fragments conjugated to an M cell targeting ligand induces an enhanced immune response and protection against RSV infection. AB - Human respiratory syncytial virus (RSV) is a major paediatric health concern worldwide. The development of an effective and safe vaccine against RSV is urgently needed. As RSV infects via the mucosal surfaces, developing a nasal vaccine may offer protective benefits over alternative administration routes. In this study, we tested a recombinant protein FG-Gb1 as an intranasal vaccine candidate against RSV. FG-Gb1 consists of the core fragments of the RSV fusion (F) and attachment (G) proteins conjugated to an microfold (M) cell-specific ligand Gb-1. Intranasal immunization with FG-Gb1 induced efficient systemic and mucosal immune responses as measured by the level of antigen-specific antibodies, cytokine-secreting cells and antigen-specific lymphocyte proliferation after exposure to antigen. Moreover, intranasal immunization induced protective immunity against nasal challenge with RSV, which was confirmed by a lack of weight loss and by viral clearance after challenge. Collectively, we confirmed that a ligand capable of targeting the conjugated antigen to nasopharynx associated lymphoid tissue (NALT) can be used as an effective nasal vaccine adjuvant to induce protective immunity against RSV infection. Moreover, FG-Gb1 may have promise as an RSV vaccine but requires further studies. PMID- 30290197 TI - Fluoxetine can inhibit coxsackievirus-B4 E2 in vitro and in vivo. AB - Group B Coxsackieviruses (CV-B) are responsible for various acute human diseases, and they are involved in chronic diseases such as type 1 diabetes. It has been reported that fluoxetine (FLX) inhibited CV-B4E2 in human cell lines in vitro. In so far as CV-B4E2 can replicate in CD1 mice, it was investigated whether FLX could inhibit CV-B4E2 in vitro and in vivo in mouse systems. When 5.5 MUM FLX was added to CV-B4E2-infected Min-6 cell (murine pancreas beta cell line) cultures, the virus-induced cytopathic effect was inhibited. In this system and in CV-B4E2 infected CD1 mouse pancreatic organotypic cultures treated with FLX the levels of infectious particles in supernatant fluids were below the limit of detection of the assay. The administration of FLX (10 mg/kg/day) by intraperitoneal route resulted in significant reduced levels of infectious particles in heart and pancreas of mice inoculated with CV-B4E2 by the same route. In conclusion FLX can inhibit CV-B4 in vitro and in vivo in mouse systems, additional studies are needed to investigate further the potential value of FLX to combat CV-B4 infections and to treat CV-B4-induced diseases. PMID- 30290198 TI - The relationship between naturalistic sleep variation and error monitoring in young adults: An event-related potential (ERP) study. AB - Sleep deprivation studies have highlighted the importance of adequate sleep for optimal daytime functioning. However, there is limited research exploring whether variations in natural sleep patterns produce similar difficulties to those seen in sleep deprivation studies. The aim of the current study was to explore whether naturalistic reductions in sleep duration and/or sleep quality were associated with behavioural and electrophysiological measures of cognitive control. Sixty undergraduate students were asked to wear an actigraph for 7 consecutive nights before completing a hybrid Flanker-Go/NoGo task whilst continuous EEG data were recorded. Participants were assigned to high or low sleep quality and short or long sleep duration groups using the National Sleep Foundation guidelines. Results indicated that individuals who, on average, slept <7 h each night showed inefficiencies in error-monitoring, as reflected by a reduction in amplitude of the error-related negativity (ERN) in comparison to those with longer sleep duration. These findings suggest that natural variations in sleep quantity are associated with atypical error detection. PMID- 30290199 TI - Effects of exposure to extremely low-frequency electromagnetic fields on spatial and passive avoidance learning and memory, anxiety-like behavior and oxidative stress in male rats. AB - There are many controversies about the safety of extremely low-frequency electromagnetic field (ELF-EMF) on body health and cognitive performance. In the present study, we explored the effects of ELF-EMF on oxidative stress and behaviors of rats. Seventy-two adult male Wistar rats were randomly divided into following groups, control, sham exposure group and the ELF-EMF exposure groups (1 MUT, 100 MUT, 500 MUT, and 2000 MUT). After 60 days exposure (2 h/day), elevated plus maze (EPM), Morris water maze (MWM) and Passive avoidance learning (PAL) tasks were used to evaluate the anxiety-like behavior, spatial and passive learning and memory, respectively. Some days after behavioral examination, oxidative stress markers were measured. During spatial reference memory test, animals in ELF-EMF exposure groups (100, and 2000 MUT) spent more time in target zone (F (4, 55) = 5.699, P = 0.0007, One-way ANOVA). In PAL retention, the step through latency in the retention test (STLr) in ELF-EMF exposure groups (100,500, and 2000 MUT) was significantly greater than control group (F (4, 55) = 29.13, P < 0.0001, One-way ANOVA). In EPM test, ELF-EMF exposure (500 and 2000 MUT) decreased the percentage of the entries into the open arms (F (4, 55) = 26.31, P < 0.0001, one-way ANOVA). ELF-EMF exposure (100, and 500 MUT) increased Malondialdehyde (MDA) concentration (F (4, 25) = 79.83, P < 0.0001, One-way ANOVA). Our results may allow the conclusion that exposure to ELF-EMFs can improve memory retention (but not acquisition) in the adult male rats. Although exposure to ELF-EMFs could be a factor in the development of anxious state or oxidative stress. PMID- 30290200 TI - Endocannabinoids, exercise, pain, and a path to health with aging. AB - Physical activity is an important lifestyle factor for growth, development, and sustained health throughout life. In recent years, the benefits of physical activity have drawn more attention to its physiological effects on the body, including well-being. The endocannabinoid system (ECS) has emerged as a focal point to ascertain the mechanisms for how exercise benefits the body and how it reduces or controls pain. The ECS, its ligands [the endocannabinoids (eCB)], receptors (CB1 and CB2), enzymes for the synthesis and degradation of eCB, and the polyunsaturated fatty acids (PUFA) that serve as substrates, comprise a powerful biological organization of multiple controls that affects mood, inflammation, pain, and other neurological aspects of the central nervous system and peripheral nervous system. Recently, investigators have reported increases in circulating levels of eCB after exercise, with some eCB exerting analgesic effects from exercise. The focus of this review is to discuss evidence for the role of eCB and the complexities of the ECS in exercise and pain. Some aspects presented herein are production of eCB and activation of the cannabinoid receptors in the brain following exercise; eCB, pain, and physical activity; oxylipins; and joint pain. Future research on the ECS must include mechanistic approaches to endocannabinoid signaling and explain the role of dietary PUFA in altering signaling of the receptors that affects pain. Additionally, how other types of exercise, such as Tai Chi, which is reported to improve well-being, should be investigated to ascertain if changes in eCB mediate the mind and body benefits of Tai Chi. As we age, exercise in the form of play has evolved with the exploration of our body from walking to running, recreational, and competitive sports, to midlife physical activity focusing on maintaining fitness and a healthy body weight. Furthermore, exercise has been a target of investigation to explore various hypotheses to explain the mechanisms for cognitive benefits in the young and in older adults. The science of exercise has matured to a level of importance in the life cycle to reduce pain with aging and include new investigations on the ECS to explain its role in well-being and improved quality of life in later years.

AB - Antidepressant drugs are recommended for the treatment of Parkinson's disease (PD)-associated depression but their role in the modulation of L-DOPA-induced behavioral and neurochemical markers is poorly explored. The aim of the present study was to examine the impact of the tricyclic antidepressant amitriptyline and L-DOPA, administered chronically alone or in combination, on rotational behavior, monoamine levels and binding of radioligands to their transporters in the dopaminergic brain structures of unilaterally 6-OHDA-lesioned rats. Binding of [3H]nisoxetine to noradrenaline transporter (NET), [3H]GBR 12,935 to dopamine transporter (DAT) and [3H]citalopram to serotonin transporter (SERT) were analyzed by autoradiography. Amitriptyline administered alone did not induce rotational behavior but in combination with L-DOPA increased the number of contralateral rotations much more strongly than L-DOPA alone. The combined treatment also significantly increased the tissue dopamine (DA) content in the ipsilateral striatum and substantia nigra (SN) vs. L-DOPA alone. 6-OHDA-mediated lesion of nigrostriatal DA neurons drastically reduced DAT and NET bindings in the ipsilateral striatum. In the ipsilateral SN, DAT binding decreased while NET binding rose. SERT binding increased significantly mainly in the SN. Amitriptyline administered alone or jointly with L-DOPA had no effect on DAT binding on the lesioned side, significantly decreased SERT binding in the striatum and SN while NET binding only in the SN. Since in the DA-denervated striatum, SERT is mainly responsible for reuptake of L-DOPA-derived DA while in the SN, SERT and NET are involved, the inhibition of these transporters by antidepressant drugs may improve dopaminergic transmission and consequently motor behavior.

The resistance genes always located in plasmids, phages and integrons, which get into bacteria cells by horizontal gene transfer (HGT). CRISPR-Cas systems are adaptive immune systems in bacteria that are beneficial to resist phage infection and other mobile genetic elements. But this can come at a cost of inhibiting the acquisition of other beneficial genes through HGT. Here, we investigate how Shigella regulate the activity of the CRISPR/Cas system spontaneously, when it wants acquire exogenous gene that is necessary for its survival. We found that IS elements were identified in cas genes, such as IS600 in cse2, ISSfl2 in cas6e, IS629 in cse1- cas3. The number of spacers in CRISPR/Cas which strain containing IS was fewer compare with none IS. Interestingly, fewer spacers were also found in multi-drug resistance Shigella strains. Furthermore, we have constructed the genetic transferred antibiotic resistant strain by resistance plasmid transfer, to detect the CRISPR/Cas system changes in this two group strains. We found that cse2 gene had a new IS elements (IS600) in the antibiotic-resistant strain. The bioinformatics analyses showed that the IS600 insert hotspots in the cse2 gene were the TGC-GGC gene motifs and the tertiary structure of the Cse2 protein was different with IS600 or not. IS600 could bring a 5-order of magnitude (105) decrease in the relative expression of cse2 gene. This study has significant implication for further revealing the mechanism underlying the CRISPR/Cas mediated antibiotic resistance gene horizontal transfer in Shigella. PMID- 30290203 TI - The crux of positive controls - Pro-inflammatory responses in lung cell models. AB - Positive controls are an important feature in experimental studies as they show the responsiveness of the model under investigation. An often applied reagent for a pro-inflammatory stimulus is the endotoxin lipopolysaccharide (LPS), which has been shown to induce a cytokine release by various cell cultures. The effect of LPS in monocultures of 16HBE14o-, a bronchial cell line, and of A549, an alveolar cell line, were compared in submerged and air-liquid interface cultures, as well as in co-cultures of the two epithelial cells with monocyte-derived macrophages and dendritic cells. The protein and mRNA levels of the two most relevant pro inflammatory mediators, Tumor necrosis factor alpha (TNF) and Interleukin 8 (CXCL8), were measured after 4 h and 24 h exposure. 16HBE14o- cells alone as well as in co-cultures are non-responsive to an LPS stimulus, but an already increased basal expression of both pro-inflammatory mediators after prolonged time in culture was observed. In contrary, A549 in monocultures showed increased CXCL8 production at the gene and protein level after LPS exposure, while TNF-levels were below detection limit. In A549 co-cultured with immune cells both mediators were upregulated. This study shows the importance of a careful evaluation of the culture system used, including the application of positive controls. In addition, the use of co-cultures with immune cells more adequately reflects the inflammatory response upon exposure to toxicants. PMID- 30290204 TI - Short term exposure to oxycodone alters the survival, proliferation and differentiation of rat embryonic neural stem cell in vitro. AB - As one of several opioids, oxycodone has been widely used, particularly in postoperative analgesia in children and cesarean section. However, the effect of oxycodone on developing brain still remains to be seen. Since there is a link between anesthetics exposure and long-term behavioral or cognitive dysfunction in young children, in the current study, the direct effect of oxycodone on neural stem cells (NSCs) biological behaviors was investigated. After exposed to a high dose of oxycodone (10 MUg/mL) for 48 h, NSCs survival and proliferation were significantly reduced, while NSCs apoptosis and differentiation were enhanced. These effects were significantly weaker than that when exposed to same dose of morphine. No significant difference was observed regarding to above biological behaviors when exposed to lower doses (0.1 MUg/mL and 1.0 MUg/mL) of oxycodone. The antagonist of opioid receptor, nalmefene, successfully reversed the influence of oxycodone. Taken together, our results indicated that short term exposure to oxycodone in low dose might be allowed for developing brain. PMID- 30290205 TI - The effects of repeated exposure and variety on vegetable intake in pre-school children. AB - Children's vegetable consumption in the UK remains lower than national recommendations, presenting potential long-term health risks. It is known that repeated exposure promotes intake of novel vegetables and that offering children variety and choice can also encourage intake. The current study aimed to compare the impact of offering variety over simple repeated exposure as a strategy for increasing pre-school children's vegetable consumption. Children (N = 95) aged 24 55 months were recruited through participating nurseries and assigned to receive repeated exposure (RE) to a single vegetable snack or a mixed snack consisting of five different vegetables (variety: V). A minimum of 5 (maximum 6) exposures were given for both RE and V conditions. Pre and post-intervention intake measures of both the RE and V snacks were taken for each child. Follow up measures took place 1 month post-intervention (n = 40). Vegetable intake increased significantly from pre to post intervention for snacks congruent to the condition to which children were assigned. Magnitude of change was smaller for the variety condition. Follow up data revealed that snack intake remained significantly higher than baseline 1 month post-intervention (p < 0.001). In agreement with previous work this study confirmed that repeated exposure was effective in promoting children's vegetable intake but there was no additional benefit of variety in this context. It may be that for moderately familiar vegetables, serving them alone encourages intake and for this age group, avoids contamination fears or effects of neophobia.

AB - Diagnoses of autism spectrum disorder (ASD) have increased considerably over the past 20 years. Because of this rise and the inherent complexity of ASD, there is a need for an increased number of scientifically valid basic and clinical research studies addressing this disorder. This manuscript serves as an introduction to the clinical presentation of ASD as well as the unique challenges and modifications required to conduct clinical research with this population. This includes detailing the current diagnostic criteria, process of receiving an ASD diagnosis, information on assessment measures, and special considerations when developing research. It is the hope that this information will provide researchers interested in conducting clinical trials with those with ASD with baseline information and considerations when developing their research topics and methodology. PMID- 30290206 TI - Repeat ablation for paroxysmal atrial fibrillation - Does adenosine play a role in predicting pulmonary vein reconnection patterns? AB - BACKGROUND: Pulmonary vein (PV) reconduction after PV isolation (PVI) unmasked by adenosine is associated with a higher risk for paroxysmal atrial fibrillation (PAF) recurrence. It is unknown if the reconnected PVs after adenosine testing and immediate re-ablation can predict reconnection and reconnection patterns of PVs at repeat procedures. We assessed reconnection of PVs with and without dormant-conduction (DC) during the first and the repeat procedure. METHODS: We included 67 patients undergoing PVI for PAF and a second procedure for PAF recurrence. DC during adenosine administration at first procedure was seen in 31 patients (46%). 264 PVs were tested with adenosine; DC was found in 48 PVs (18%) and re-ablated during first procedure. During the second procedure, all PVs where checked for reconnection. RESULTS: Fifty-eight patients (87%) showed PV reconnection during the second procedure. Reconnection was found in 152/264 PVs (58%). Of 216 PVs without reconnection during adenosine testing at the first ablation, 116 PVs (53.7%) showed reconnection at the repeat procedure. Overall, 14.9% of patients showed the same PV reconnection pattern in the first and second procedure, expected statistical probability of encountering the same reconnection pattern was only 6.6%(p = 0.012). CONCLUSIONS: In repeat procedures PVs showed significantly more often the same reconnection pattern as during first procedure than statistically expected. More than 50% of initial isolated PVs without reconnection during adenosine testing showed a reconnection during repeat ablation. Techniques to detect susceptibility for PV re-connection like prolonged waiting-period should be applied. Elimination of DC should be expanded from segmental to circumferential re-isolation or vaster RF application. PMID- 30290208 TI - Translational machine learning for psychiatric neuroimaging. AB - Despite its initial promise, neuroimaging has not been widely translated into clinical psychiatry to assist in the prediction of diagnoses, prognoses, and optimal therapeutic strategies. Machine learning approaches may enhance the translational potential of neuroimaging because they specifically focus on overcoming biases by optimizing the generalizability of pipelines that measure complex brain patterns to predict targets at a single-subject level. This article introduces some fundamentals of a translational machine learning approach before selectively reviewing literature to-date. Promising initial results are then balanced by the description of limitations that should be considered in order to interpret existing research and maximize the possibility of future translation. Future directions are then presented in order to inspire further research and progress the field towards clinical translation. PMID- 30290209 TI - Metastasis and chemoresistance in CD133 expressing pancreatic cancer cells are dependent on their lipid raft integrity. AB - Metabolic rewiring is an integral part of tumor growth. Among metabolic pathways, the Mevalonic-Acid-Pathway (MVAP) plays a key role in maintaining membrane architecture through cholesterol synthesis, thereby affecting invasiveness. In the current study, we show for the first time that CD133Hi pancreatic tumor initiating cells (TIC) have increased expression of MVAP enzymes, cholesterol content and Caveolin expression. Further, we show that CD133 in these cells is localized in the lipid-rafts (characterized by Cav-1-cholesterol association). Disruption of lipid-rafts by either depleting Cav-1 or by inhibiting MVAP by lovastatin decreased metastatic-potential and chemoresistance in CD133Hi cells while not affecting the CD133lo cells. Additionally, disruption of lipid-raft results in deregulation of FAK-signaling, decreasing invasiveness in pancreatic TICs. Furthermore, this also inhibits ABC-transporter activity resulting in sensitizing TICs to standard chemotherapeutic agents. Repurposing existing drugs for new clinical applications is one of the safest and least resource intensive approaches to improve therapeutic options. In this context, our study is extremely timely as it shows that targeting lipid-rafts with statins can sensitize the normally resistant pancreatic TICHi-cells to standard chemotherapy and decrease metastasis, thereby defining a novel strategy for targeting the TICHi-PDAC. PMID- 30290210 TI - S1PR2 antagonist alleviates oxidative stress-enhanced brain endothelial permeability by attenuating p38 and Erk1/2-dependent cPLA2 phosphorylation. AB - Both sphingosine-1-phosphate receptor-2 (S1PR2) and cytosolic phospholipase A2 (cPLA2) are implicated in the disruption of cerebrovascular integrity in experimental stroke. However, the role of S1PR2 in induction of cPLA2 phosphorylation during cerebral ischemia-induced endothelial dysfunction remains unknown. This study investigated the effect of S1PR2 blockade on oxidative stress induced cerebrovascular endothelial barrier impairment and explored the possible mechanisms. In bEnd3 cells, cPLA2 inhibitor CAY10502 as well as S1PR2 antagonist JTE013 profoundly suppressed hydrogen peroxide (H2O2)-induced changes of paracellular permeability and ZO-1 localization. Besides p38, extracellular signal-regulated kinase (Erk) 1/2 is required for H2O2-increased cPLA2 phosphorylation and endothelial permeability. Pharmacological and genetic inhibition of S1PR2 significantly suppressed their phosphorylation in response to H2O2. Especially lentivirus-mediated knockdown of S1PR2 inhibited H2O2-induced ZO 1 redistribution and paracellular hyperpermeability. Using the permanent middle cerebral artery occlusion (pMCAO) mouse model, we found JTE013 pretreatment markedly reduced Evans blue dye (EBD) extravasation and reversed the decrease in VE-cadherin, occludin, claudin-5 and CD31 expression in infarcted hemisphere. Lentivirus-mediated S1PR2 knockdown also attenuated EBD extravasation. Furthermore, JTE013 pretreatment attenuated neurological deficit, brain edema and infarction volume. Therefore, our findings suggest the protective effect of JTE013 on brain endothelial barrier integrity is likely mediated by suppressing p38 and Erk1/2-dependent cPLA2 phosphorylation under oxidative stress. PMID- 30290211 TI - Zeasesquiterpene A-E, new sesquiterpenes from the roots of Zea mays. AB - Zeasesquiterpene A-E (1-5), five new sesquiterpenes with two cyclohexanes, were isolated from the roots of Zea mays. Their structures were elucidated on the basis of 1D and 2D NMR spectral data and ECD analysis. A plausible biosynthetic pathway for the compounds (1-6) were hypothesized. All isolated compounds were screened for cytotoxicities against five human cancer cell lines (A549, MDA-MB 231, SK-Hep-1, SNU638 and HCT116) in vitro by MTT assay. Compound 4 showed potential cytotoxic activities against A549 (14.3 MUMU) and SNU638 (9.7 MUMU). By contrast, compound 1 exhibited moderate cytotoxicity to the four human cancer cell lines (A549, SK-Hep-1, SUN638 and HCT116), and the IC50 values are from 19.5 MUMU to 22.5 MUMU. PMID- 30290212 TI - The relationship between social anxiety and heartbeat evoked potential amplitude. AB - Past research suggests that social anxiety is associated with increased processing of cardiac activity. Cognitive theories propose that this is one aspect of self-focus, which is driven by concerns that features of the self, such as anxiety symptoms, will elicit evaluation from others. We investigated the relationship of social anxiety to the cortical processing of heartbeats as reflected in the heartbeat evoked potential (HEP) during false feedback of accelerated heart rate. Thirty-eight participants with high social anxiety (HSA; n = 19) and non-elevated social anxiety (NSA; n = 19) completed a cognitive task during which false feedback of accelerated heart rate was randomly provided on 50% of trials. HEP amplitude was larger in HSAs, but not NSAs, during false heartbeat acceleration cues compared to standard cues. HEP amplitude also was larger in HSAs compared to NSAs during acceleration cues. HEP amplitude during acceleration cues, but not standard cues correlated with social anxiety. Within the first second after the R-peak, social anxiety correlated with voltage at Fz from 223 to 305 ms. Social concerns about the consequences of anxiety symptoms accounted for an indirect relationship between social anxiety and the HEP. These data extend prior evidence of increased processing of cardiac activity in socially anxious individuals, providing support for cognitive theories. PMID- 30290213 TI - The role of the amygdala in enhanced remembrance of negative episodes and acquired negativity of related neutral cues. AB - Prior research on the interaction between emotion and episodic memory established that negatively charged events are better remembered compared to neutral events (i.e. enhanced remembrance), as well as that a priori neutral cues that were present in the environment during a negative event can attain aversive meaning by themselves (i.e. acquired negativity). Improved understanding the neural mechanisms that mediate enhanced remembrance of negative episodes and acquired negativity of related neutral cues may carry substantial clinical relevance, particularly in the context of posttraumatic pathophysiology. In order to address this point forty-nine healthy participants completed a novel fMRI task that involve the presentation of neutral pictures before and after a series of short neutral and aversive video-clips from which the neutral pictures were originally extracted, and a subsequent presentation of these pictures as cues for clip recall [termed, Picture-Clip-Picture-Recall (PCPR) task]. Behavioral results indicate that aversive clips were indeed better remembered compared to neutral clips (i.e. enhanced remembrance of negative episode) and that a priori neutral pictures that appeared in aversive clips were rated more negatively after relative to before the exposure to the aversive clips (i.e. acquired negativity of related neutral cues). Whole-brain fMRI analysis revealed that increased amygdala activation in response to pictures when presented as cues for clip recall predicted successful clip remembrance, particularly remembrance of aversive clips. This amygdala activation was also correlated with the magnitude of acquired negativity of the cues following their appearance in aversive clips. Taken together our findings implicate the PCPR as a novel, naturalistic, framework for investigating the neural interface of emotional episodic memory, while highlighting the role of the amygdala in enhanced remembrance of negative episodes and acquired negativity of related neutral cues. Clinical implications are discussed. PMID- 30290214 TI - Effects of the pesticide chlorpyrifos on breast cancer disease. Implication of epigenetic mechanisms. AB - Chlorpyrifos (CPF) is an organophosphorus pesticide used for agricultural pest control all over the world. We have previously demonstrated that environmental concentrations of this pesticide alter mammary gland histological structure and hormonal balance in rats chronically exposed. In this work, we analyzed the effects of CPF on mammary tumors development. Our results demonstrated that CPF increases tumor incidence and reduces latency of NMU-induced mammary tumors. Although no changes were observed in tumor growth rate, we found a reduced steroid hormone receptor expression in the tumors of animals exposed to the pesticide. Moreover, we analyzed the role of epigenetic mechanisms in CPF effects. Our results indicated that CPF alters HDAC1 mRNA expression in mammary gland, although no changes were observed in DNA methylation. In summary, we demonstrate that the exposure to CPF promotes mammary tumors development with a reduced steroid receptors expression. It has also been found that CPF affects HDAC1 mRNA levels in mammary tissue pointing that CPF may act as a breast cancer risk factor. PMID- 30290215 TI - Caspases orchestrate microglia instrumental functions. AB - Microglia, the resident immune cells of the brain, can acquire various cell phenotypes based on their location and current role. This level of plasticity is required to fulfil the vast variety of functions that microglia perform. Adequate microglial functions are crucial for a healthy brain. However, microglial activation can also contribute to both degenerative/traumatic and proliferative diseases. We review current evidence supporting roles for caspases, a family of proteases, in the overall control of microglia, from the regulation of their activation, their biological functions, to their death. Further, we discuss possible roles for these microglial caspase-dependent signaling pathways in brain diseases. PMID- 30290216 TI - Natural activators of adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) and their pharmacological activities. AB - Adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) is a heterotrimeric enzyme which monitors cellular energy status and regulates metabolism with energy balance. AMPK activation, as a master regulator of metabolism, plays role in key tissues like liver, skeletal muscles, and heart as well as central nervous system (CNS). Activation of the enzyme by indirect activators attracts scientific attentions to treat diabetes, obesity, cancer, and other related metabolic disorders like physiological and pathophysiological states in CNS. A number of hormones and pharmacological agents have been reported to activate AMPK including paroxetine, metformin, thiazolidinediones, adiponectin, leptin, interleukin-6, and etc. AMPK activity is prominent in regulation of glucose, lipid, and proteins metabolism as well as mitochondrial biogenesis and autophagy. Activation of AMPK in the liver decrease blood glucose and in skeletal muscles stimulates glucose uptake independently of insulin through modulation of activity of several downstream substrates. Activation of AMPK inhibits synthesis and induces oxidation of fatty acids, which may reduce ectopic lipid accumulation and improve insulin action. The enzyme activation promotes cardiovascular homeostasis by ensuring optimum redox balance of heart and vascular tissue. In addition, AMPK signaling may link to cancer development via regulation of checkpoints of cell cycle. Numerous of conventional drugs have been derived from natural resources, while the application of this fruitful source of chemical structures have not been explored in depth. A number of these compounds are discussed in this review that exhibit beneficial effects in metabolic disorders through AMPK activation. PMID- 30290217 TI - Novel ABCA1 peptide agonists with antidiabetic action. AB - Previously, apoE-derived ABCA1 agonist peptides have been shown to possess anti atherosclerotic and possibly antidiabetic properties. Here we assessed the in vitro and in vivo actions of a second generation of ABCA1 peptide agonists, CS6253 and T6991-2, on glucose homeostasis. The results show that these two peptides improve glucose tolerance in a prediabetic diet-induced obesity mouse model by enhancing insulin secretion. It was further demonstrated that T6991-2 also improved glucose tolerance in leptin-deficient (ob/ob) mice. CS6253 increased insulin secretion both under basal conditions and in response to high glucose stimulation in pancreatic INS-1 beta-cells rendered leptin receptor deficient with specific siRNA. Additional in vitro cell studies suggest that the CS6253 agonist attenuates hepatic gluconeogenesis and glucose transport. It also potentiates insulin-stimulated glucose uptake and utilization. These observed anti-diabetic actions suggest additional benefits of the CS6253 and T6991-2 ABCA1 peptide agonists for cardiovascular disease beyond their direct anti atherosclerosis properties previously described. PMID- 30290218 TI - Targeting glutathione S-transferase P and its interactome with selenium compounds in cancer therapy. AB - The glutathione (GSH) S-transferase family of detoxification and signalling proteins represents a major hub for the metabolism of Selenium-derived compounds. At the same time, these compounds can be used to modulate the expression and multiple activities of GSTs and other glutathione-dependent genes, that are important aspects in both the chemoprevention and therapy of drug-resistant cancers. In this context, the isoform GSTP-1 (GSTP) appears to play a fundamental role. Besides promoting GSH-dependent detoxification of cellular electrophiles, GSTP physically interacts with a number of small molecules and cellular proteins producing regulatory effects across the main signal transduction and transcription pathways (identified as the "regulatory interactome of GSTP"). An emerging molecular mechanism behind such regulatory function is the activity of GSTP as a redox chaperonine responsible for the selective glutathionylation of protein Cys residues in the different subcellular compartments. The redox sensitive transcription factor Nrf2 was recently identified as one of the regulatory nodes of this interactome at the interface between inflammation, adaptive stress response, and cell death pathways. The influence of Nrf2 in the stress response to cellular electrophiles and its regulatory interaction with GSTP are discussed in this review suggesting the hypothesis that this interaction may represent the actual pharmacological target of Se compounds with thiol peroxidase activity. These points are critically evaluated with a view to further development of these compounds in cancer prevention and the chemotherapy of drug resistant tumours. PMID- 30290219 TI - An improved water-soluble prodrug of propofol with high molecular utilization and rapid onset of action. AB - Water-soluble prodrugs of propofol often carry an excess of propofol at the effective dose and have a slower onset of action. Sustained release of the original drug can result in propofol accumulation in the body after administration, causing delays in wakefulness. This situation causes the prodrug to lose the benefits of rapid onset and recovery from the effects of propofol. In the present study, HX0921 (sodium 2-(2-(2,6-diisopropylphenoxy)-2 oxoethoxy)acetate), an improved prodrug of propofol with high utilization of propofol and fast onset of action, was studied. The rate of propofol release from HX0921 was much faster than that from fospropofol (a marketed propofol prodrug) in rat plasma. The 50% effective dose (ED50) of propofol, HX0921 and fospropofol to induce anesthesia in rats was 5.78, 22.19 and 42.44 mg/kg, respectively. After administration at 2 * ED50, the onset time of anesthesia in the HX0921 group was significantly shorter than that in the fospropofol group (0.26 +/- 0.15 min vs. 2.24 +/- 0.35 min, P < 0.01) and the duration of anesthesia in the HX0921 group was also significantly shorter than that in the fospropofol group (22.35 +/- 4.05 min vs. 29.15 +/- 5.25 min, P < 0.01). These results suggest that the rapid onset and short action time of HX0921 was due to the rapid release and high molecular utilization of propofol carried by HX0921. PMID- 30290220 TI - Production of Phosphorylated Ric-8A proteins using protein kinase CK2. AB - Resistance to Inhibitors of Cholinesterase-8 (Ric-8) proteins are molecular chaperones that fold heterotrimeric G protein alpha subunits shortly after biosynthesis. Ric-8 proteins also act as test tube guanine nucleotide exchange factors (GEF) that promote Galpha subunit GDP for GTP exchange. The GEF and chaperoning activities of Ric-8A are regulated by phosphorylation of five serine and threonine residues within protein kinase CK2 consensus sites. The traditional way that Ric-8A proteins have been purified is from Spodoptera frugiperda (Sf9) or Trichoplusia ni (Tni) insect cells. Endogenous insect cell kinases do phosphorylate the critical regulatory sites of recombinant Ric-8A reasonably well, but there is batch-to-batch variability among recombinant Ric-8A preparations. Additionally, insect cell-production of some Ric-8 proteins with phosphosite alanine substitution mutations is proscribed as there seems to be interdependency of multi-site phosphorylation for functional protein production. Here, we present a method to produce wild type and phosphosite mutant Ric-8A proteins that are fully occupied with bound phosphate at each of the regulatory positions. Ric-8A proteins were expressed and purified from E. coli. Purified Ric 8A was phosphorylated in vitro with protein kinase CK2 and then re-isolated to remove kinase. The phosphorylated Ric-8A proteins were ~99% pure and the completeness of phosphorylation was verified by chromatography, phos-tag SDS-PAGE mobility shifts, immunoblotting using phospho-site specific antibodies, and mass spectrometry analysis. E. coli-produced Ric-8A that was phosphorylated using this method promoted a faster rate of Galpha subunit guanine nucleotide exchange than Ric-8A that was variably phosphorylated during production in insect cells. PMID- 30290221 TI - A complete enzymatic capacity for long-chain polyunsaturated fatty acid biosynthesis is present in the Amazonian teleost tambaqui, Colossoma macropomum. AB - In vertebrates, the essential fatty acids (FA) that satisfy the dietary requirements for a given species depend upon its desaturation and elongation capabilities to convert the C18 polyunsaturated fatty acids (PUFA), namely linoleic acid (LA, 18:2n-6) and alpha-linolenic acid (ALA, 18:3n-3), into the biologically active long-chain (C20-24) polyunsaturated fatty acids (LC-PUFA), including arachidonic acid (ARA, 20:4n-6), eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3). Recent studies have established that tambaqui (Colossoma macropomum), an important aquaculture-produced species in Brazil, is a herbivorous fish that can fulfil its essential FA requirements with dietary provision C18 PUFA LA and ALA, although the molecular mechanisms underpinning such ability remained unclear. The present study aimed at cloning and functionally characterizing genes encoding key desaturase and elongase enzymes, namely fads2, elovl5 and elovl2, involved in the LC-PUFA biosynthetic pathways in tambaqui. First, a fads2-like desaturase was isolated from tambaqui. When expressed in yeast, the tambaqui Fads2 showed Delta6, Delta5 and Delta8 desaturase capacities within the same enzyme, enabling all desaturation reactions required for ARA, EPA and DHA biosynthesis. Moreover, tambaqui possesses two elongases that are bona fide orthologs of elovl5 and elovl2. Their functional characterization confirmed that they can operate towards a variety of PUFA substrates with chain lengths ranging from 18 to 22 carbons. Overall our results provide compelling evidence that demonstrates that all the desaturase and elongase activities required to convert LA and ALA into ARA, EPA and DHA are present in tambaqui within the three genes studied herein, i.e. fads2, elovl5 and elovl2. PMID- 30290222 TI - Idebenone is a cytoprotective insulin sensitizer whose mechanism is Shc inhibition. AB - When insulin binds insulin receptor, IRS1 signaling is stimulated to trigger the maximal insulin response. p52Shc protein competes directly with IRS1, thus damping and diverting maximal insulin response. Genetic reduction of p52Shc minimizes competition with IRS1, and improves insulin signaling and glucose control in mice, and improves pathophysiological consequences of hyperglycemia. Given the multiple benefits of Shc reduction in vivo, we investigated whether any of 1680 drugs used in humans may function as Shc inhibitors, and thus potentially serve as novel anti-diabetics. Of the 1680, 30 insulin sensitizers were identified by screening in vitro, and of these 30 we demonstrated that 7 bound Shc protein. Of the 7 drugs, idebenone dose-dependently bound Shc protein in the 50-100 nM range, and induced insulin sensitivity and cytoprotection in this same 100 nM range that clinically dosed idebenone reaches in human plasma. By contrast we observe mitochondrial effects of idebenone in the 5,000 nM range that are not reached in human dosing. Multiple assays of target engagement demonstrate that idebenone physically interacts with Shc protein. Idebenone sensitizes mice to insulin in two different mouse models of prediabetes. Genetic depletion of idebenone's target eliminates idebenone's ability to insulin-sensitize in vivo. Thus, idebenone is the first-in-class member of a novel category of insulin sensitizing and cytoprotective agents, the Shc inhibitors. Idebenone is an approved drug and could be considered for other indications such as type 2 diabetes and fatty liver disease, in which insulin resistance occurs.

AB - Invasion of host cells by apicomplexan parasites is mediated by proteins released from microneme, rhoptry, and dense granule secretory organelles located at the apical end of parasite invasive forms. Microneme secreted proteins establish interactions with host cell receptors and induce exocytosis of the rhoptry organelle. Rhoptry proteins are involved in target cell invasion as well as the formation of the parasitophorous vacuole in which parasites reside during development within the host cell. In Plasmodium merozoites, the rhoptry neck protein (RON) complex consists of RON2, RON4, and RON5, and interacts with apical membrane antigen 1 (AMA1) as a critical structure of the invasion moving junction. PfRON12 is known to localize to the rhoptry neck of merozoites, but its function remains obscure. The roles of RON proteins are largely unknown in sporozoites, the second invasive form of Plasmodium which possesses a conserved apical end secretory structure. Here, we confirm that RON12 is expressed in the rhoptry neck of merozoites in rodent malaria parasites, whereas in contrast we show that RON12 is localized to the rhoptry body in sporozoites. Phenotypic analysis of Plasmodium berghei ron12-disrupted mutants revealed that RON12 is dispensable for sporogony, invasion of mosquito salivary glands and mouse hepatocytes, and development in hepatocytes. PMID- 30290225 TI - Flow cytometric assessment of leukocyte kinetics for the monitoring of tissue damage. AB - Leukocyte populations quickly respond to tissue damage, but most leukocyte kinetic studies are not based on multiparameter flow cytometry. We systematically investigated several blood leukocyte populations after controlled tissue damage. 48 patients were assigned to either an anterior or posterolateral total hip arthroplasty. Peripheral blood was collected pre-operatively and at 2 h, 24 h, 48 h, 2 and 6 weeks postoperatively and assessed by flow cytometry for absolute counts of multiple leukocyte populations using standardized EuroFlow protocols. Absolute counts of leukocyte subsets differed significantly between consecutive time points. Neutrophils increased instantly after surgery, while most leukocyte subsets initially decreased, followed by increasing cell counts until 48 h. At two weeks all leukocyte counts were restored to pre-operative counts. Immune cell kinetics upon acute tissue damage exhibit reproducible patterns, which differ between the leukocyte subsets and with "opposite kinetics" among monocyte subsets. Flow cytometric leukocyte monitoring can be used to minimally invasively monitor tissue damage. PMID- 30290226 TI - Mesenchymal stem cell-driven activatable photosensitizers for precision photodynamic oncotherapy. AB - Precise targeting with minimal side effects is of particular interest for personalized medicine, although it remains a challenge. Herein, we demonstrate precision photodynamic therapy (PDT) utilizing human mesenchymal stem cells (MSCs) as cellular vehicles to deliver a new activatable photosensitizer (PcS). In vivo real-time optical imaging tests indicated that PcS-loaded MSCs possess excellent tumor-homing properties. More importantly, dye transfer assays confirm that MSCs precisely transfer PcS into human colon cancer cells (HCT116) via the "bystander effect." Upon localized light irradiation, the growth of intraperitoneal xenograft tumors was significantly inhibited by the photodynamic effect. These findings represent a promising strategy for precise oncotherapy. PMID- 30290227 TI - The role of PNPLA1 in omega-O-acylceramide synthesis and skin barrier function. AB - The human genome encodes nine enzymes belonging to the patatin-like phospholipase domain-containing lipase (PNPLA)/Ca2+-independent phospholipase A2 (iPLA2) family. Although most PNPLA/iPLA2 enzymes are widely distributed and act on phospholipids or neutral lipids as (phospho)lipases to play homeostatic roles in lipid metabolism, the function of PNPLA1 remained a mystery until a few years ago. However, the recent finding that mutations in the human PNPLA1 gene are linked to autosomal recessive congenital ichthyosis (ARCI), as well as evidence obtained from biochemical and gene knockout studies, has shed light on the function of this enzyme in skin-specific sphingolipid metabolism rather than glycerophospholipid metabolism. PNPLA1 is specifically expressed in differentiated keratinocytes and plays a crucial role in the biosynthesis of omega-O-acylceramide, a particular class of sphingolipids that is essential for skin barrier function. PNPLA1 acts as a unique transacylase that specifically transfers linoleic acid from triglyceride to omega-hydroxy fatty acid in ceramide, thus giving rise to omega-O-acylceramide. In this review, we overview the biosynthetic route and biological role of epidermal omega-O-acylceramide, highlight the function of PNPLA1 as a bona fide acylceramide synthase required for proper skin barrier function and keratinocyte differentiation, and summarize the mutations of PNPLA1 currently identified in ARCI patients.

PMID- 30290228 TI - A comparison of growth among growth friendly systems for scoliosis: a systematic review. AB - BACKGROUND: The optimal method for surgical treatment of early onset scoliosis is currently unknown. Although the aim of growth-friendly systems is to reduce the curve and maintain growth, there is no consensus on how to measure spinal growth during and after the treatment. Different measurements of different segments (T1 S1, T1-T12, instrumented length) are used for different time points to evaluate growth. The aim of this review is to assess what measurements are used and to compare the growth-friendly systems based on spinal growth during treatment. METHODS: The electronic MEDLINE, EMBASE and Cochrane databases were systematically searched for original articles that reported growth for traditional growing rods (TGR), VEPTR, Shilla, Magnetically controlled growing rods (MCGR) and Luque-trolley systems. All measurements were recorded and weighted averages calculated in centimeter per year were compared. RESULTS: We included 52 studies (26 TGR, 12 MCGR, 6 VEPTR, 4 Luque-trolley, 1 Shilla and 3 mixed). Often only one segment was reported (T1-S1 length in 22 studies, T1-T12 length in 2 studies and instrumented length in 5 studies). The remaining 22 studies reported T1-S1 length in combination with T1-T12 length (15 studies) or instrumented length (8 studies). Spinal growth achieved by initial correction only, was a considerable 3.9 cm (based on 34 studies) as well as the spinal growth achieved by the final fusion surgery (2.3 cm in 4 studies). To specifically assess growth achieved with the system, length gain after initial surgery and before final fusion in growth system graduates was considered. Only 4 TGR studies reported on this "true" spinal growth with 0.6 cm and 0.3 cm per year in the T1-S1 and T1-T12 segment respectively. CONCLUSION: Reporting on spinal growth is currently inadequate and does not allow a good comparison of different techniques. However, all systems often report growth similar to Dimeglio's T1-S1 spinal growth of 1 cm per year. It should be recognized though that a considerable portion of the reported spinal growth is due to the initial and final surgical correction and not due to the growth-friendly implant. PMID- 30290229 TI - The m6A-methylase complex and mRNA export. AB - During synthesis, mRNA undergoes a number of modifications such as capping, splicing and polyadenylation. These processes are coupled with the orderly deposition of the TREX complex on the mRNA and subsequent recruitment of the NXF1 P15 heterodimer which stimulates the nuclear export of mature mRNAs. mRNAs also undergo a number of internal modifications, the most common of which is the N6 methyladenosine (m6A) modification. In this review we discuss the recent evidence of coupling between the m6A modification, RNA processing and export. PMID- 30290230 TI - Dissecting cellulitis of the scalp successfully treated with ALA-PDT: Case report. AB - A case of recalcitrant dissecting cellulitis of the scalp (DCS) in a 23-year-old male patient was treated with 4 times of topical ALA-PDT at intervals of 10-15 days. The patient responded well without any unbearable adverse effects and presented satisfactory effects. Before applying this therapy, the patient and his doctors had tried other methods, specifically glucocorticoids, intradermal injection, and even surgical treatment, but none of them had presented satisfactory effects. This suggests that topical ALA-PDT could be an effective and safe alternative for DCS patients who are refractory to other standard therapies. PMID- 30290231 TI - Skin permeation, biocompatibility and antitumor effect of chloroaluminum phthalocyanine associated to oleic acid in lipid nanoparticles. AB - The objective of this study was to develop and characterize lipid nanoparticles (LNs) containing chloroaluminum phthalocyanine (ClAlPc) to reduce the aggregation of the drug and improve its skin penetration and its antitumor effect. LNs were prepared and characterized by using stearic acid (SA) as solid lipid and oleic acid (OA) as liquid lipid in different proportions. in vitro and in vivo skin penetration was evaluated using modified Franz diffusion cells and fluorescence microscopy, respectively. in vitro biocompatibility and Photodynamic Therapy (PDT) were performed using L929-fibroblasts cell line and A549 cancer cell line and melanoma BF16-F10, respectively. OA promoted the increase in the encapsulation efficiency and drug loading, reaching values of 95.8% and 4%, respectively. The formulation with 40% OA (NLC 40) showed a significantly higher (p < 0.01) amount of drug retained in the skin compared to other formulations. All formulations developed were considered biocompatible. PDT evidenced the antitumor efficacy of NLC 40 with reduced cell viability for approximately 10% of cancer cells, demonstrating that the presence of OA in the NLC seems to potentialize this antitumor effect. PDT in BF16-F10 melanoma using NLC 40 resulted in a reduction in mean cell viability of approximately 99%. According to the results obtained, the systems developed may be promising for the incorporation of ClAlPc in the treatment of skin cancer by photodynamic therapy. PMID- 30290232 TI - Microsatellite-based genetic diversity of Dermacentor reticulatus in Europe. AB - Dermacentor reticulatus, also known as ornate dog tick, is an important vector of the causative agents of various tick-borne diseases in humans, livestock and wild animals. The geographical range of D. reticulatus in Europe is fragmented and divided into two main zones: The Western European and the Eastern European zone. To investigate D. reticulatus population structure through its distribution range we used microsatellite markers and compared the genetic diversity of D. reticulatus in 26 selected sites in the western and eastern European distribution areas. A total of 254 unfed adult D. reticulatus ticks were collected from vegetation and genotyped at 5 microsatellite loci, and altogether 26 alleles were detected. The overall FST value of pairwise comparisons among 26 sampling sites was 0.128 and revealed a moderate genetic differentiation. Bayesian-clustering analysis showed that D. reticulatus forms two genetically distinct groups across Europe. Division of D. reticulatus distribution range into Eastern European and Western European populations with a possible recent overlap in Poland has been supported by molecular data obtained in this study. PMID- 30290233 TI - Defining the pathogenic threat of envenoming by South African shield-nosed and coral snakes (genus Aspidelaps), and revealing the likely efficacy of available antivenom. AB - While envenoming by the southern African shield-nosed or coral snakes (genus Aspidelaps) has caused fatalities, bites are uncommon. Consequently, this venom is not used in the mixture of snake venoms used to immunise horses for the manufacture of regional SAIMR (South African Institute for Medical Research) polyvalent antivenom. Aspidelaps species are even excluded from the manufacturer's list of venomous snakes that can be treated by this highly effective product. This leaves clinicians, albeit rarely, in a therapeutic vacuum when treating envenoming by these snakes. This is a significantly understudied small group of nocturnal snakes and little is known about their venom compositions and toxicities. Using a murine preclinical model, this study determined that the paralysing toxicity of venoms from Aspidelaps scutatus intermedius, A. lubricus cowlesi and A. l. lubricus approached that of venoms from highly neurotoxic African cobras and mambas. This finding was consistent with the cross-genus dominance of venom three-finger toxins, including numerous isoforms which showed extensive interspecific variation. Our comprehensive analysis of venom proteomes showed that the three Aspidelaps species possess highly similar venom proteomic compositions. We also revealed that the SAIMR polyvalent antivenom cross-reacted extensively in vitro with venom proteins of the three Aspidelaps. Importantly, this cross-genus venom-IgG binding translated to preclinical (in a murine model) neutralisation of A. s. intermedius venom induced lethality by the SAIMR polyvalent antivenom, at doses comparable with those that neutralise venom from the cape cobra (Naja nivea), which the antivenom is directed against. Our results suggest a wider than anticipated clinical utility of the SAIMR polyvalent antivenom, and here we seek to inform southern African clinicians that this readily available antivenom is likely to prove effective for victims of Aspidelaps envenoming. BIOLOGICAL SIGNIFICANCE: Coral and shield-nosed snakes (genus Aspidelaps) comprise two species and several subspecies of potentially medically important venomous snakes distributed in Namibia, Botswana, Zimbabwe, Mozambique and South Africa. Documented human fatalities, although rare, have occurred from both A. lubricus and A. scutatus. However, their venom proteomes and the pathological effects of envenomings by this understudied group of nocturnal snakes remain uncharacterised. Furthermore, no commercial antivenom is made using venom from species of the genus Aspidelaps. To fill this gap, we have conducted a transcriptomics-guided comparative proteomics analysis of the venoms of the intermediate shield-nose snake (A. s. intermedius), southern coral snake (A. l. lubricus), and Cowle's shield snake (A. l. cowlesi); investigated the mechanism of action underpinning lethality by A. s. intermedius in the murine model; and assessed the in vitro immunoreactivity of the SAIMR polyvalent antivenom towards the venom toxins of A. l. lubricus and A. l. cowlesi, and the in vivo capability of this antivenom at neutralising the lethal effect of A. s. intermedius venom. Our data revealed a high degree of conservation of the global composition of the three Aspidelaps venom proteomes, all characterised by the overwhelming predominance of neurotoxic 3FTxs, which induced classical signs of systemic neurotoxicity in mice. The SAIMR polyvalent antivenom extensively binds to Aspidelaps venom toxins and neutralised, with a potency of 0.235 mg venom/mL antivenom, the lethal effect of A. s. intermedius venom. Our data suggest that the SAIMR antivenom could be a useful therapeutic tool for treating human envenomings by Aspidelaps species. PMID- 30290234 TI - Alterations in non-type I collagen biomarkers in osteogenesis imperfecta. AB - Osteogenesis imperfecta [1] is a rare disorder of connective tissue caused by abnormalities in the synthesis or processing of type I collagen. Type I collagen is the most abundant type of collagen and is expressed in almost all connective tissues. Given that type I collagen interacts with other collagens based in the extracellular matrix (ECM), we hypothesized changes in type I collagen in OI would result in perturbations in the homeostasis of other collagen types. We measured serum biomarkers of several non-type I collagens in patients with mild (type I) and moderate-to-severe (type III/IV) OI. Compared to controls, those with moderate-to severe OI had a higher mean level of the synthesis markers of collagen III (ProC3) (P = 0.02), and levels of collagen V (ProC5) (P = 0.07) were slightly, but not significantly, higher. Degradation markers of collage type IV (C4M2) (P = 0.04) and type VI (C6M) (P = 0.003) were also higher. In each case, a test for trend suggested levels were higher in moderate-to-severe OI, intermediate in mild OI, and lowest in controls (P = 0.06-0.002). These changes supports the hypothesis that mutations in type I collagen induce a widespread alteration in the ECM, and that the diverse clinical manifestations of OI reflect an extensive disruption in ECM biology. PMID- 30290235 TI - Sleep and circadian rhythms as possible trait markers of suicide attempt in bipolar disorders: An actigraphy study. AB - BACKGROUND: The poor prognostic of Bipolar disorders (BD) is closely linked to deaths by suicide. Sleep and circadian abnormalities are observed during all phases of BD and are also associated with suicide attempt (SA). In this context, this study sought to identify specific sleep and circadian rhythms markers associated with suicidal attempt in euthymic patients with BD. METHODS: The sample (N = 236) comprised 3 groups: 147 patients with BD including 57 with a history of SA and 90 without (NoSA), and 89 healthy controls (HC). All participants were recorded during 21 days with actigraphy. RESULTS: SA was associated with women gender (p = 0.03), familial history of SA (p = 0.03), mixed episodes (p = 0.001), and benzodiazepines (p = 0.019). SA, compared to noSA, had a morning phase preference (p = 0.04), and were more vigorous on the circadian type inventory (p = 0.04), and tended to suffer more from insomnia (45% versus 25% respectively, p = 0.10). SA was also associated with an earlier onset of daily activity assessed with actigraphy (M10 onset: p = 0.01). Backward stepwise linear regression indicated that a combination of four variables (Gender, vigour, insomnia, M10onset) significantly differentiated patients with SA from NoSA (p = 0.03). LIMITATIONS: Cross-sectional design, and no examination of suicidal behaviors' subgroups such as first attempters or repeaters, or violent suicide attempt. CONCLUSIONS: Woman gender, vigorous circadian type, insomnia and an earlier daily activity appeared independently associated with SA in BD. If these biomarkers are confirmed in prospective studies, they should be screened and used to prevent suicide, with the development of personal and targeted chronobiological treatments. PMID- 30290237 TI - Methionine supplementation stimulates mitochondrial respiration. AB - Mitochondria play essential metabolic functions in eukaryotes. Although their major role is the generation of energy in the form of ATP, they are also involved in maintenance of cellular redox state, conversion and biosynthesis of metabolites and signal transduction. Most mitochondrial functions are conserved in eukaryotic systems and mitochondrial dysfunctions trigger several human diseases. By using multi-omics approach, we investigate the effect of methionine supplementation on yeast cellular metabolism, considering its role in the regulation of key cellular processes. Methionine supplementation induces an up regulation of proteins related to mitochondrial functions such as TCA cycle, electron transport chain and respiration, combined with an enhancement of mitochondrial pyruvate uptake and TCA cycle activity. This metabolic signature is more noticeable in cells lacking Snf1/AMPK, the conserved signalling regulator of energy homeostasis. Remarkably, snf1Delta cells strongly depend on mitochondrial respiration and suppression of pyruvate transport is detrimental for this mutant in methionine condition, indicating that respiration mostly relies on pyruvate flux into mitochondrial pathways. These data provide new insights into the regulation of mitochondrial metabolism and extends our understanding on the role of methionine in regulating energy signalling pathways. PMID- 30290236 TI - Rapid and accurate analysis of stem cell-derived extracellular vesicles with super resolution microscopy and live imaging. AB - Extracellular vesicles (EVs) have prevalent roles in cancer biology and regenerative medicine. Conventional techniques for characterising EVs including electron microscopy (EM), nanoparticle tracking analysis (NTA) and tuneable resistive pulse sensing (TRPS), have been reported to produce high variability in particle count (EM) and poor sensitivity in detecting EVs below 50 nm in size (NTA and TRPS), making accurate and unbiased EV analysis technically challenging. This study introduces direct stochastic optical reconstruction microscopy (d STORM) as an efficient and reliable characterisation approach for stem cell derived EVs. Using a photo-switchable lipid dye, d-STORM imaging enabled rapid detection of EVs down to 20-30 nm in size with higher sensitivity and lower variability compared to EM, NTA and TRPS techniques. Imaging of EV uptake by live stem cells in culture further confirmed the potential of this approach for downstream cell biology applications and for the analysis of vesicle-based cell cell communication. PMID- 30290238 TI - From APOBEC to ZAP: Diverse mechanisms used by cellular restriction factors to inhibit virus infections. AB - Antiviral restriction factors are cellular proteins that inhibit the entry, replication, or spread of viruses. These proteins are critical components of the innate immune system and function to limit the severity and host range of virus infections. Here we review the current knowledge on the mechanisms of action of several restriction factors that affect multiple viruses at distinct stages of their life cycles. For example, APOBEC3G deaminates cytosines to hypermutate reverse transcribed viral DNA; IFITM3 alters membranes to inhibit virus membrane fusion; MXA/B oligomerize on viral protein complexes to inhibit virus replication; SAMHD1 decreases dNTP intracellular concentrations to prevent reverse transcription of retrovirus genomes; tetherin prevents release of budding virions from cells; Viperin catalyzes formation of a nucleoside analogue that inhibits viral RNA polymerases; and ZAP binds virus RNAs to target them for degradation. We also discuss countermeasures employed by specific viruses against these restriction factors, and mention secondary functions of several of these factors in modulating immune responses. These important examples highlight the diverse strategies cells have evolved to combat virus infections. PMID- 30290239 TI - Induction of early growth response gene 1 (EGR1) by endoplasmic reticulum stress is mediated by the extracellular regulated kinase (ERK) arm of the MAPK pathways. AB - Endoplasmic reticulum (ER) stress activates three principal signaling pathways, collectively known as the unfolded protein response, leading to translational and transcriptional control mechanisms that dictate the cell's response as adaptive or apoptotic. The present study illustrates that for HepG2 human hepatocellular carcinoma cells the signaling pathways triggered by ER stress extend beyond the three principal pathways to include mitogen-activated protein kinase (MAPK) signaling, leading to activation of transcription from the early growth response 1 (EGR1) gene. Analysis provided evidence for a SRC-RAS-RAF-MEK-ERK cascade mechanism that leads to enhanced phosphorylation of the transcription factor ELK1. ELK1 and serum response factor (SRF) are constitutively bound to the EGR1 promoter and are phosphorylated by nuclear localized ERK. The promoter abundance of both phospho-SRF and phopsho-ELK1 was increased by ER stress, but the SRF phosphorylation was transient. Knockdown of ELK1 had little effect on the basal EGR1 mRNA content, but completely blocked the increase in response to ER stress. Conversely, knockdown of SRF suppressed basal EGR1 mRNA content, but had only a small effect on the induction by ER stress. This research highlights the importance of MAPK signaling in response to ER stress and identifies ELK1 as a transcriptional mediator and the EGR1 gene as a target. PMID- 30290240 TI - Adducins inhibit lung cancer cell migration through mechanisms involving regulation of cell-matrix adhesion and cadherin-11 expression. AB - Cell migration is a critical mechanism controlling tissue morphogenesis, epithelial wound healing and tumor metastasis. Migrating cells depend on orchestrated remodeling of the plasma membrane and the underlying actin cytoskeleton, which is regulated by the spectrin-adducin-based membrane skeleton. Expression of adducins is altered during tumorigenesis, however, their involvement in metastatic dissemination of tumor cells remains poorly characterized. This study investigated the roles of alpha-adducin (ADD1) and gamma-adducin (ADD3) in regulating migration and invasion of non-small cell lung cancer (NSCLC) cells. ADD1 was mislocalized, whereas ADD3 was markedly downregulated in NSCLC cells with the invasive mesenchymal phenotype. CRISPR/Cas9 mediated knockout of ADD1 and ADD3 in epithelial-type NSCLC and normal bronchial epithelial cells promoted their Boyden chamber migration and Matrigel invasion. Furthermore, overexpression of ADD1, but not ADD3, in mesenchymal-type NSCLC cells decreased cell migration and invasion. ADD1-overexpressing NSCLC cells demonstrated increased adhesion to the extracellular matrix (ECM), accompanied by enhanced assembly of focal adhesions and hyperphosphorylation of Src and paxillin. The increased adhesiveness and decreased motility of ADD1 overexpressing cells were reversed by siRNA-mediated knockdown of Src. By contrast, the accelerated migration of ADD1 and ADD3-depleted NSCLC cells was ECM adhesion-independent and was driven by the upregulated expression of pro-motile cadherin-11. Overall, our findings reveal a novel function of adducins as negative regulators of NSCLC cell migration and invasion, which could be essential for limiting lung cancer progression and metastasis. PMID- 30290242 TI - Tub and beta-catenin play a key role in insulin and leptin resistance-induced pancreatic beta-cell differentiation. AB - The aim of this study was to investigate the molecular mechanism of pancreatic islet-derived mesenchymal stem cell (PID-MSC) differentiation into beta-cells in the presence of insulin and leptin resistance stimulators. We determined that beta-cell differentiation was stimulated by glucose, insulin, and leptin. Co administration of insulin and leptin resulted in greater, at a further stage of differentiation but non-functional beta-cell formation. The levels of p AKT(Ser473) did not change; SOCS3, PTP1B, p-IRS1(Ser307), PTEN levels increased and p-IRS1(Try) levels decreased due to insulin and leptin co-administration. These findings suggest that co-administration of insulin and leptin to PID-MSCs results in the development of both insulin and leptin resistance together. We showed that this differentiation signaling is mainly mediated by AKT/GSK 3beta/beta-catenin and Tub. Moreover, beta-catenin and Tub were linked to each other in the nucleus under this condition. Furthermore, we found that Tub and beta-catenin contributes to insulin production by increasing the expression of transcription factors by binding to the promoter regions of ins1, ins2, and pdx1 genes. In addition, Tub is also bound to the promoter region of the MafA gene. These findings demonstrate that when insulin and leptin resistance develop together in rat PID-MSCs beta-cell differentiation increases markedly via beta catenin and Tub. New therapeutic agents that inhibit AKT/GSK-3beta/beta-catenin and in particular Tub may help prevent the development or retard the progression of type 2 diabetes. PMID- 30290243 TI - Peptide-decorated polymeric nanomedicines for precision cancer therapy. AB - The advancement of tissue and cell-specific drug delivery systems is a key to precision cancer therapy. Peptides, with easy synthesis, low immunogenicity and biological functions closely mimicking or surpassing natural proteins, have been actively engineered and explored to provide nanomedicines with the ability to overcome various extracellular and intracellular delivery barriers ranging from phagocytic clearance in the circulation, low tumor penetration, poor cancer cell selectivity, inferior cell penetration, to endosomal entrapment as well as poor blood brain barrier permeation for brain cancer therapy. Anti-tumor studies with peptide-decorated polymeric nanomedicines are currently in the experimental stage. Most of the reported peptide-directed polymeric nanomedicines do have a rather complex design requiring a multi-step reproducible fabrication process. Moreover, many of the proposed peptide-decorated polymeric nanomedicines are still not able to effectively overcome the drug delivery cascade barriers. Consequently, in order to facilitate clinical translation the complexity of the systems has to be reduced, while maintaining the added functions after the introduction of the different peptides and further progress has to be made in passing the various drug delivery barriers. In this review, we give an overview of the rational design, development and preclinical performance of peptide decorated polymeric nanomedicines, and further discuss their challenges and future perspectives as a next generation cancer treatment modality. PMID- 30290244 TI - Potent in vivo lung cancer Wnt signaling inhibition via cyclodextrin-LGK974 inclusion complexes. AB - Activation of the Wnt signaling pathway promotes lung cancer progression and contributes to poor patient prognosis. The porcupine inhibitor LGK974, a novel orally bioavailable cancer therapeutic in Phase I clinical trials, induces potent Wnt signaling inhibition and leads to suppressed growth and progression of multiple types of cancers. The clinical use of LGK974, however, is limited in part due to its low solubility and high toxicity in tissues that rely on Wnt signaling for normal homeostasis. Here, we report the use of host-guest chemistry to enhance the solubility and bioavailability of LGK974 in mice through complexation with cyclodextrins (CD). We assessed the effects of these complexes to inhibit Wnt signaling in lung adenocarcinomas that are typically driven by overactive Wnt signaling. 2D 1H NMR confirmed host-guest complexation of CDs with LGK974. CD:LGK974 complexes significantly decreased the expression of Wnt target genes in lung cancer organoids and in lung cancer allografts in mice. Further, CD:LGK974 complexes increased the bioavailability upon oral administration in mice compared to free LGK974. In a mouse lung cancer allograft model, CD:LGK974 complexes induced potent Wnt signaling inhibition with reduced intestinal toxicity compared to treatment with free drug. Collectively, the development of these complexes enables safer and repeated oral or parenteral administration of Wnt signaling inhibitors, which hold promise for the treatment of multiple types of malignancies. PMID- 30290241 TI - Who guards the guardian? Mechanisms that restrain APC/C during the cell cycle. AB - The cell cycle is principally controlled by Cyclin Dependent Kinases (CDKs), whose oscillating activities are determined by binding to Cyclin coactivators. Cyclins exhibit dynamic changes in abundance as cells pass through the cell cycle. The sequential, timed accumulation and degradation of Cyclins, as well as many other proteins, imposes order on the cell cycle and contributes to genome maintenance. The destruction of many cell cycle regulated proteins, including Cyclins A and B, is controlled by a large, multi-subunit E3 ubiquitin ligase termed the Anaphase Promoting Complex/Cyclosome (APC/C). APC/C activity is tightly regulated during the cell cycle. Its activation state increases dramatically in mid-mitosis and it remains active until the end of G1 phase. Following its mandatory inactivation at the G1/S boundary, APC/C activity remains low until the subsequent mitosis. Due to its role in guarding against the inappropriate or untimely accumulation of Cyclins, the APC/C is a core component of the cell cycle oscillator. In addition to the regulation of Cyclins, APC/C controls the degradation of many other substrates. Therefore, it is vital that the activity of APC/C itself be tightly guarded. The APC/C is most well studied for its role and regulation during mitosis. However, the APC/C also plays a similarly important and conserved role in the maintenance of G1 phase. Here we review the diverse mechanisms counteracting APC/C activity throughout the cell cycle and the importance of their coordinated actions on cell growth, proliferation, and disease. PMID- 30290245 TI - Exosomes: natural nanoparticles as bio shuttles for RNAi delivery. AB - Application of exosomes, natural nanoscale vesicles, as specific delivery vehicles has received considerable attention in recent past years. The presence of various adhesive proteins on the surface of these lipid bilayers, gives them the ability to interact with cellular membranes. Although the function of exosomes was not known for some time, further researches have suggested that they are effective in multiple cellular pathways, as well as pathogenesis of a broad range of diseases including neurodegenerative diseases, cardiovascular diseases, and more importantly, multiple human malignancies. As erstwhile research brought to light more aspects of exosomes' biogenesis and functions, researchers sought to benefit from their effects in therapeutic and diagnostic purposes. Gene therapy is one of these fields that has seen many endeavors made. The present review article looks at gene therapy and its latest advancements, structure and function of exosomes and their role as bio shuttles in various clinical contexts relating to gene therapy. PMID- 30290246 TI - Prospective evaluation of the adaptive immune response to SlpA in Clostridium difficile infection. AB - Clostridium difficile is a major cause of healthcare-associated diarrhea. SlpA is the precursor of the S-layer of C. difficile. The aim of this work was to evaluate the humoral immune response of hospitalized patients to SlpA and its potential role on CDI outcome. Sera of 87 included patients were collected the day of CDI diagnosis as well as at early and late periods after infection. SlpA appeared to be immunogenic with a heterogeneous response between patients after a CDI. Patients with a single episode had a significantly higher anti-SlpA IgG antibody level than patients with recurrent CDI (p = 0.0197). These preliminary results will be useful to understand better the inter-individual variability of immune responses to C. difficile as well as for the development of new therapeutics. PMID- 30290247 TI - Transcranial direct current stimulation modulates the brain's response to foot stimuli under dual-task condition: A fMRI study in elderly adults. AB - Previous behavioral studies have shown that high-intensity cognitive tasks weaken balance control in elder adults. Moreover, age-related loss of plantar sensation is considered to be an important contributing factor to the occurrence of falls. Recently, we have realized that transcranial direct current stimulation (tDCS) can effectively improve the balance of the elderly under the dual-task, but its underlying regulatory mechanism is not clear. In this study, task functional Magnetic Resonance Imaging (fMRI) was used to study the brain's response to foot stimuli under foot stimuli or dual-task (foot stimuli and cognitive task) conditions to explain the effect of the addition of cognitive tasks during balance in 16 healthy elderly adults. To study whether tDCS would counteract the effect of the added cognitive task, we further compared the differences in activity of the cerebral cortices of dual-task and tDCS-dual-task conditions. The results suggested added cognitive tasks significantly attenuated the response of the brain to foot stimuli in elderly adults. Moreover, the cortex excitability weakened by cognitive tasks was significantly promoted after 20 min of tDCS. In conclusion, a portion of the resources originally used for plantar sensory processing may be assigned to the processing of the cognitive task when the cognitive tasks are added, which results in insufficient resources for plantar sensory processing. tDCS improves the ability of the brain to respond to foot stimuli by modulating the excitability of the cognitive cortex and reverses the effects of cognitive tasks. PMID- 30290248 TI - Zebrafish bio-assay guided isolation of human acetylcholinesterase inhibitory trans-tephrostachin from Tephrosia purpurea (L.) Pers. AB - An acetylcholinesterase inhibitory compound was isolated from Tephrosia purpurea (L.) Pers. by zebrafish brain based bioassay guided isolation and predicted as trans-tephrostachin.Enzyme kinetics studies (Line weaver-Burk plots and Michaelis Menten equation) favored the reversible / mixed type, with the inhibition constant (Ki) of 53.0 +/- 7.4 MUM in zebrafish brain (IC50 value of 39.0 +/- 1.4 MUM). However, the inhibition constant (Ki) was found to be 36.0 +/- 0.4 MUM with IC50 value of 20.0 +/- 1.0 MUM, whereas donepezil showed 3.2 +/- 0.3 MUM with the IC50 value of 0.12 +/- 0.04 MUM for human acetylcholinesterase. Further, the molecular docking, dynamics and simulation for trans-tephrostachin obtained better binding affinity and efficacy than commercial drugs donepezil and galanthamine. Hence, the isolated compound trans - tephrostachin from T. purpurea shall be further considered for the development of potential drug for the counteraction of Alzheimer's disease progression. PMID- 30290249 TI - Non-invasive mapping of glutathione levels in mouse brains by in vivo electron paramagnetic resonance (EPR) imaging: Applied to a kindling mouse model. AB - Glutathione (GSH) is an important antioxidant that can protect cells under oxidative stress. Thus, a non-invasive method to measure and map the distribution of GSH in live animals is needed. To image the distribution of GSH levels in specific brain regions, a new method using electron paramagnetic resonance (EPR) imaging with a nitroxide imaging probe was developed. Pixel-based mapping of brain GSH levels was successfully obtained by using the linear relationship between reduction rates for nitroxides in brains, measured by an in vivo EPR imager, and brain GSH levels, measured by an in vitro biochemical assay. The newly developed method was applied to a kindling mouse model induced with pentylenetetrazole (PTZ) to visualize changes in GSH levels in specific brain regions after seizure. The obtained map of brain GSH levels clearly indicated decreased GSH levels around the hippocampal region compared to control mice.

AB - An efficient method was developed to prepare oxidized potato starch under the pasting point by Electro-Fenton system, in which a complex of sodium citrate and Fe2+ (SC-Fe2+) was used as catalyst, and H2O2 was used as oxidant. In the preparation process the oxidation degree of starch was controlled by the molar ratios of SC-Fe2+ and hydrogen peroxide. The structures and thermal properties of the prepared oxidized starch were characterized by FT-IR, XRD, SEM, DSC and DTG. The characterization results indicated that the obtained oxidized potato starch owned one grainy molecule structure, and displayed a high viscosity (not less than 63 Pa.s) by comparing to the raw starch. The carbonyl and carboxyl contents of oxidized potato starch achieved 0.81 per 100 AGU and 0.79 per 100 AGU, respectively after the raw starch was oxidized. And the oxidized starch showed good thermal stability, which can dramatically improve the application performance of starch-based biomaterials. PMID- 30290251 TI - Isolation and characterization of a galactose-specific lectin (EantH) with antimicrobial activity from Euphorbia antiquorum L. latex. AB - A homodimeric 75 kDa lectin with hemagglutination activity (HA) was purified from the crude latex of Euphorbia antiquorum L. by two types of chromatography, on cation exchange (HiTrap SP FF) and hydrophobic HiTrap Phenyl FF (high sub) columns. The purified protein was designated EantH, and is classified as a galactose-specific thermostable lectin. The HA of EantH was stable at pH values of 5-9 and temperature 5-65 degrees C. The lectin had bacteriostatic action on the Gram-positive bacteria Staphylococcus aureus and S. epidermidis, with a minimum inhibitory concentration (MIC) of 2000 MUg/ml and on a Gram-negative bacterium Samonella typhimurium, with a MIC of 1000 MUg/ml. EantH inhibited the growth of Propionibacterium acnes and Streptococcus agalactiae with MIC of 125 MUg/ml and 250 MUg/ml, respectively. EantH killed P. acnes and S. agalactiae with a minimum microbicidal concentration (MMC) of 1000 MUg/ml and 2000 MUg/ml, respectively. Scanning electron microscopy indicated that binding of EantH to the carbohydrates in the cell walls of P. acnes and S. typhimurium drastically altered the bacterial cells, and led to inhibition of growth and/or cell death. The antimicrobial activity of EantH could be neutralized by d-galactose, indicating that its bactericidal action involves binding to galactose in the cell wall. PMID- 30290252 TI - Fabrication and characterization of composite cryobeads based on chitosan and starches-g-PAN as efficient and reusable biosorbents for removal of Cu2+, Ni2+, and Co2+ ions. AB - Novel composite biosorbents were developed in this work as cryobeads by dual cross-linking of a mixture of chitosan (CS) and starch coming from different botanical sources, such as potato, wheat, and rice, grafted with poly(acrylonitrile) (PAN). Glutaraldehyde and poly(ethylene glycol diglycidyl ether) were used as cross-linkers. Composite cryobeads were characterized by FTIR, SEM-EDX, and swelling kinetics. Sorption of Cu2+, Ni2+, and Co2+ onto the novel biosorbents was investigated as a function of time and the concentration of the metal ion, at the optimum pH and sorbent dose. Pseudo-second-order kinetic model and Elovich model well fitted the kinetic results, indicating chemisorption as the most probable mechanism of sorption, while the Langmuir, and Sips isotherm models described the sorption at equilibrium for all metal ions. The values of the maximum sorption capacity of Cu2+, Ni2+, and Co2+ onto the composite sorbent based on CS and rice starch-g-PAN were as follows: 100.6 mg/g, 83.25 mg/g, and 74.01 mg/g, respectively. The nitrile groups present in the biocomposites CS/starch-g-PAN constitute a source to further increase the sorption capacity by their hydrolysis. A remarkable level of reusability was found for the composite cryobeads, no decrease of the sorption capacity being observed after five consecutive sorption/desorption cycles. PMID- 30290253 TI - Influence of photoinitiator concentration and irradiation time on the crosslinking performance of visible-light activated pullulan-HEMA hydrogels. AB - In-situ forming hydrogels were prepared from pullulan-HEMA copolymer using three component visible-light system composed of camphorquinone carboxylic acid-folic acid-iodonium salt. The relevance of double bond conversion and crosslinking density of hydrogels with the photoinitiator concentration and irradiation time were estimated by FT-IR analysis and swelling calculation using Flory-Rehner theory, respectively. The results revealed that the crosslinking density and degree of conversion of hydrogels were improved by photoinitiator concentration increasing until certain extend, then they decreased due to a primary radicals termination reaction occurred. The shortest irradiation time of 10 s was essential to obtain acceptable hydrogels for further characterizations. For the probability use of hydrogels as scaffold was investigated in vitro by measuring of the indirect cytotoxicity assay by MTT-assay using human bone Sarcoma cell as a reference cell lines. The majority of seeded SW1353 cells maintained a live with an accepted viability of ~85-92% over a four days culture period with irradiation of hydrogel 10 s, while cell viability has improved to ~95-98% with prolonging the irradiation time of hydrogel to 60 s. The current photoinitiating system is a proper system for in-situ crosslinking the activated-light biomaterials for bone regeneration, dental, or tissue engineering applications. PMID- 30290254 TI - Low-resolution envelope, biophysical analysis and biochemical characterization of a short-chain specific and halotolerant carboxylesterase from Bacillus licheniformis. AB - Esterases are widely applied in industrial processes due to their versatility, regio- and enantioselectivity, lack of cofactors and stability in organic solvents. Bacillus licheniformis, a microorganism frequently used in industrial and biotechnological applications such as dairy, baking, beverage, pulp and paper, detergent and cosmetics production, organic synthesis and waste management, is a promising source of esterases. Here we describe the biochemical and biophysical characterization of B. licheniformis carboxylesterase BlEst1 and its SAXS-derived molecular envelope. BlEst1 has optimal hydrolytic activity against p-nitrophenyl acetate at pH 7.0 and 40 degrees C. Furthermore, BlEst1 is stable in different organic solvents such as methanol, isopropanol and butanol. The BlEst1 homology model reveals a typical alpha/beta hydrolase core with an adjacent auxiliary domain, snuggly fitting the experimental low-resolution SAXS molecular envelope. Moreover, BlEst1 maintained considerable part of its activity in the presence of up to 5 M NaCl and its thermal stability was significantly enhanced by the presence of salt, revealing its halotolerant character. The ability to work under harsh conditions makes BlEst1 an interesting candidate for industrial applications. PMID- 30290255 TI - Comparative analysis of two mitochondrial genomes of flesh flies (Sarcophaga antilope and Sarcophaga dux) with phylogeny and evolutionary timescale for Sarcophagidae. AB - The complete mitochondrial genomes (mitogenomes) of two flesh flies (Sarcophaga antilope Bottcher and Sarcophaga dux Thomson) are amplified, sequenced, annotated, analyzed, and compared with 13 other species of the family Sarcophagidae. The mitogenomes of S. antilope and S. dux are 15,196 bp and 15,731 bp long, respectively, and each contains the typical set of 37 genes (13 protein coding genes (PCGs), 22 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes) and a non-coding control region with identical gene arrangement as typical arthropod mitogenome. The phylogenetic trees inferred from Bayesian inference (BI) and maximum likelihood (ML) analysis for 15 sarcophagid and five outgroup taxa are congruent, both not supporting the monophyly of Sarcophagidae but supporting the subfamily Sarcophaginae as a monophyletic group and the tribal relationship "Boettcheriini + (Raviniini + (Parasacophagini + Sarcophagini))". The molecular dating analyses indicate the Sarcophagidae was first divided within the Late Eocene epoch (35.52 million years ago (Mya), 95% high posterior density (HPD) interval: 26.70-45.01 Mya), and most Sarcophagini species diverged during the Miocene epoch (<17.09 Mya, 95% HPD: 10.76-24.36 Mya). PMID- 30290256 TI - Protective roles of Amanita caesarea polysaccharides against Alzheimer's disease via Nrf2 pathway. AB - This study explores the neuro-protective effects of Amanita caesarea polysaccharides (ACPS), obtained by 80% alcohol precipitation of water extract and purified using a DEAE-52 cellulose anion exchange column, related to antioxidant activity. A 3-h pre-treatment of ACPS prior to l-glutamic acid (l Glu) co-exposure reversed the decreased cell viability, inhibited apoptosis, suppressed the accumulation of intracellular reactive oxygen species and restored mitochondrial membrane potential in HT22 cells. Compared to l-Glu-exposed cells, ACPS enhanced the nuclear levels of NF-E2p45-related factor 2 (Nrf2), reduced the cytoplasmic levels of Nrf2 and cytochrome C, suppressed the expression of Kelch like ECH-associated protein 1, and enhanced the expression of heme oxygenase-1, superoxide dismutase 1 and cysteine ligase catalytic subunit. In a d-galactose and aluminum trichloride Alzheimer's disease (AD) mouse model, 42-day administration of ACPS improved the abnormal behaviors. ACPS suppressed the deposition of beta-amyloid peptide in the brain and ameliorated oxidative stress via modulating the levels of related enzymes. ACPS improved the functioning of the central cholinergic system, as indicated by an increase in acetylcholine and choline acetyltransferase concentrations, and reduced acetylcholine esterase levels in the serum, hypothalamus and cerebral cortex. Our data suggest that ACPS may be a promising candidate for the treatment of AD. PMID- 30290257 TI - Evaluation of the production of exopolysaccharide by plant growth promoting yeast Rhodotorula sp. strain CAH2 under abiotic stress conditions. AB - The capability of plant growth promoting microbes to survive under abiotic stresses has important significance for improving plant growth and productivity. Among the various plant growth promoting biomolecules produced by microbes, exopolysaccharide (EPS) help microbes to survive in inhospitable environments and endure environmental stressful conditions. In the present study, a yeast strain CAH2 was isolated from Beta vulgaris rhizosphere soil and identified as Rhodotorula sp., based on the partial 18S rRNA gene sequence analysis. Rhodotorula sp. strain CAH2 was found to tolerate higher concentrations of Al (6 mM), NaCl (150 mM) and PEG-6000 (15%, w/v). The strain CAH2 was shown to produce 7.5 g L-1 of EPS in the production medium with sucrose and yeast extract as a carbon and nitrogen sources, respectively. The EPS yield was increased constantly with increasing concentrations of Al, NaCl and PEG-6000. The structural feature of EPS studied through FT-IR and NMR spectral analysis confirmed the presence of glucose, mannose and galactose. The yeast strain CAH2 was produced multiple plant growth promoting traits in the presence and absence of abiotic stresses. Finally, these results indicate that the production of EPS could be safeguard the plant growth promoting Rhodotorula sp. strain CAH2 from unfavourable environmental conditions. PMID- 30290258 TI - Doxorubicin-loaded casein nanoparticles for drug delivery: Preparation, characterization and in vitro evaluation. AB - Casein, a milk protein that self-assembles to form micelles in aqueous solution, can bind to a wide range of drugs (hydrophilic and hydrophobic). Herein, a low cost and facile method was reported to prepare casein nanoparticles loaded with an anticancer drug, doxorubicin (DOX). The particles were fabricated by adding an excess of Ca2+ ions which brings the soluble casein present in the solution into the micellar framework to form dense nanoparticles. The binding between the drug and the macromolecule was confirmed using fluorescence studies. Circular Dichroism (CD) shows that upon addition of excess Ca2+ the protein chains rearrange. The nanoparticles were characterized by transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), and dynamic light scattering (DLS). The release at pH 1 was higher than the physiological pH making this formulation potent for delivering the drug to the stomach via the oral route. The DOX attached with casein showed improved efficacy, i.e., better cytotoxicity against human pancreatic carcinoma cell line, PANC 1 cells as compared to the free drug of the same concentration, owing to higher cell uptake of the macromolecule. PMID- 30290259 TI - Influence of the ionic strength on the amyloid fibrillogenesis of hen egg white lysozyme. AB - The study investigates the role of the electrostatic interactions in the fibrillation of the hen egg white lysozyme (HEWL). In order to achieve this aim the influence of the cations Na+, Mg2+ and Al3+ on the amyloid fibril formation and amorphous aggregation was tested. The amyloids are formed in the solution without added salt but the Thioflavin T fluorescence gives the false-negative result. In these conditions, the HEWL fibrils are long and curvy. If the ionic strength of the solution is sufficiently high, the formed amyloids are shorter and fragmented. Our study shows that the addition of the aluminium salt promotes protein fibrillation. The amorphous aggregation dominates in the high concentration of electrolyte. The in vitro amyloid fibril formation seems to be regulated by universal mechanisms. The theories implemented in the polymer science or for colloidal solutions give the qualitative description of the aggregation phenomena. However, the specific interactions and the additional effects (e.g. fibril fragmentation) modulate the amyloidogenesis. PMID- 30290260 TI - Overexpression of secreted sucrose isomerase in Yarrowia lipolytica and its application in isomaltulose production after immobilization. AB - Isomaltulose production by bacterial fermentation was limited, due to generation of undesirable products and reduced yields. Isomaltulose production using sucrose isomerase (SIase) catalyzed methods was expected to be more applicable, but was hampered by low SIase activity and lack of a secreted SIase producer. Here, we aimed to obtain high levels of secreted SIase by overexpressing the SIase gene from Pantoea dispersa UQ68J in Yarrowia lipolytica, a successful host for efficient secretory expression, with a newly characterized strong constitutive promoter. After optimization of the culture medium, the engineered strain JD secreted SIase with an activity of 49.3 U/mL. The recombinant SIase was effectively immobilized onto polyvinyl alcohol-alginate, and the enzymatic activity recovery rate was up to 82.4%. The stability of the SIase was significantly improved by immobilization. Batch production of isomaltulose catalyzed by the immobilized SIase was performed under optimal conditions, generating 620.7 g/L isomaltulose with a yield of 0.96 g/g. The conversion rate of sucrose after 13 batches remained above 90%. These results demonstrated that the proposed SIase expression and immobilization method was promising in the industrial production of isomaltulose. PMID- 30290261 TI - Influence of spray-drying, freeze-drying and vacuum-drying on physicochemical and functional properties of gelatin from Labeo rohita swim bladder. AB - Influence of different drying method on yield, physicochemical and functional properties of gelatin from rohu (Labeo rohita) swim bladder were investigated. Freeze-drying presented the highest gelatin yield (54.51 g/100 g, dry weight basis), followed by vacuum-drying (48.95 g/100 g) and spray-drying (41.76 g/100 g), respectively (P < 0.05). All gelatin samples showed glycine as the major amino acid followed by proline, glutamic acid, alanine, arginine and hydroxyproline, respectively. Freeze-dried gelatin (FDG) and spray-dried gelatin (SDG) showed alpha (alpha1 and alpha2), beta-chains and gamma-chain as the predominant components, whereas an absence of beta- and gamma-chains found in vacuum-dried gelatin (VDG). FTIR spectra revealed that the loss of the triple helix was found in all gelatins which indicated the conversion of collagen to soluble gelatin. FDG and SDG had the highest surface hydrophobicity, protein solubility, emulsifying, foaming and gelation property than VDG (P < 0.05). Moreover, SDG showed slightly higher surface hydrophobicity, protein solubility, emulsifying and foaming properties as compared to FDG (P < 0.05). However, no significant difference was found in gelation properties of FDG and SDG (P > 0.05). Therefore, freeze-drying or spray-drying could be an appropriate drying method for preparation of gelatin from rohu swim bladder with better functionalities. PMID- 30290262 TI - A novel milk-clotting cysteine protease from Ficus johannis: Purification and characterization. AB - Due to the need for calf rennet alternatives, many attempts have been made to find new proteases. A novel cysteine protease with milk-clotting activity was purified from Ficus johannis by cation exchange chromatography. The protease was stable in various pH (3.0-10.5) with the optimum at 6.5 and showed its maximum activity at 60 degrees C. The Km and Vmax values of the enzyme were obtained to be 0.604 mg/ml and 0.0273 MUmol Tyr/min, respectively. The purified protease exhibited considerable activity towards kappa-casein in comparison to alpha casein and beta-casein. The enzyme was almost completely active in the presence of high salt concentrations. Besides, it had high stability against autodigestion. The content of free amino acids was determined by HPLC, where leucine, lysine, valine, gamma-aminobutyric acid and tyrosine were the most abundant amino acids. The cheese manufactured by using the purified protease showed similar textural properties and physico-chemical compositions to cheese produced using commercial rennet. Considering the special characteristics, including high milk-clotting activity, considerable stability over wide ranges of pH and temperature, resistance towards solvents, salts, and surfactants, the new protease might be the promising candidate for the dairy industry as well as other food and biotechnological industries. PMID- 30290263 TI - Up- and downregulation of mature miR-1587 function by modulating its G-quadruplex structure and using small molecules. AB - Using bioinformatics analysis, we found some mature human miRNAs containing G rich sequences with four G-tracts that had a high probability of forming G quadruplex structures. Here, we chose G-rich miR-1587 as a model to characterize the function and regulation of miRNAs. Using electrospray ionization mass spectrometry, magnetic resonance imaging, circular dichroism spectrometry, we had confirmed that miR-1587 folded into a stable parallel G-quadruplex structure. By microarray, Q-RT-PCR and 3'UTR luciferase assay, TAGLN, an early marker of smooth muscle differentiation and tumor suppressor, was identified as a target gene of miR-1587, thus providing a direct target to study miR-1587 functions. We identified three aspects of miR-1587 regulation: 1) KCl induced miR-1587 G quadruplex formation, reducing the interaction between miR-1587 and the target gene, and inhibiting miR-1587 function; 2) pseudopalmatine ligand further inhibited miR-1587 binding to TAGLN mRNA, which disrupted its function and increased the TAGLN expression; 3) the addition of TMPyP4 ligand interfered G quadruplex formation, and significantly enhanced miR-1587 regulation of TAGLN expression. This study has revealed the possibility of using the G-quadruplex structure as a strategy to regulate miR-1587 function, showing potential for the development of up- and downregulation of mature G-rich microRNA function by modulating its G-quadruplex and using small molecules. PMID- 30290264 TI - Structure characterization and anti-leukemia activity of a novel polysaccharide from Angelica sinensis (Oliv.) Diels. AB - A new water-soluble polysaccharide, APS-1II, with a molecular weight of 42.1 kDa was isolated from the roots of Angelica sinensis (Oliv.) Diels. APS-1II consists of arabinose (Ara), glucose (Glc) and fucose (Fuc) with a molar ratio of 2.48:1.05:1.00. The backbone of APS-1II is composed of 1,3-alpha-l-Araf and 1,6 alpha-d-Glcp with the branches containing 1,5-alpha-l-Araf, 1,4-beta-d-Glcp, T beta-d-Glcp, 1,3-alpha-l-Fucp and T-alpha-l-Fucp. APS-1II inhibited the proliferation of human leukemia K562 and mouse L1210 cells in vitro and markedly prolonged the life span of L1210-bearing mice in vivo. APS-1II also increased the numbers of leukocytes and lymphocytes in peripheral blood, and significantly decreased plasma tumor necrosis factor, interleukin-2 and interferon-gamma levels in L1210-bearing mice. Moreover, APS-1II administration concentration-dependently promoted the proliferation of the splenocytes, enhanced phagocytic activity of peritoneal macrophages and cytotoxicity of natural killer cells. These results suggest that APS-1II could effectively inhibit leukemia and induce a protective immune response, and it may be used as a suitable candidate reagent for leukemia therapy. PMID- 30290265 TI - Role of cell division protein divIVA in Enterococcus faecalis pathogenesis, biofilm and drug resistance: A future perspective by in silico approaches. AB - Antibiotics resistance is the major problem in clinical settings which leads to the emergence of drug resistant bacteria. Biofilm formation is one of the grounds for the emergence of antibiotics resistant strains of Enterococcus faecalis. Our group previously reported in a comparative proteomic study of biofilm and planktonic state of E. faecalis that cell division protein divIVA was two folds overexpressed in biofilm state as compared to planktonic one and suggested its involvement in biofilm formation and antibiotics resistance. In this in silico study molecular docking showed that DNA bind to the conserved amino acid residues of divIVA domain and suggested that divIVA possibly secretes DNA into extra polymeric substance (EPS) which is the part of biofilm. We also performed the STRING analysis of cell division protein divIVA and predicted their interactive partners {cell division proteins/divisome complex (ftsZ, ftsA, divIV, ftsL, & gpsB), hypothetical proteins (sepF, EF_0261, EF_1000, EF_0998, EF_1006 & EF_1040), isoleucyl-tRNA synthetase (ileS), septation ring formation regulator (ezrA), S4 domain-containing protein (EF_1001), rod shape-determining protein (mreC), UDP-N-acetylmuramoyl-L-alanyl-d-glutamate synthetase (murD), UDP diphospho-muramoyl-pentapeptide beta-N- acetylglucosaminyltransferase (murG), Lipoprotein signal peptidase (lspA), adenylate kinase (adk) and DNA-binding response regulator (vicR)}. We suggest that cumulatively divIVA and its interactive partners might be directly or indirectly involved in E. faecalis cell division, growth, biofilm formation, virulence and resistance. PMID- 30290266 TI - Esculin prevents Lipopolysaccharide/D-Galactosamine-induced acute liver injury in mice. AB - Liver injury is an important cause of serious liver disease and is characterized by inflammatory and oxidative responses. Esculin, a coumarinic derivative found in Aesculus hippocastanum L., has been shown to exhibit anti-inflammatory and anti-oxidative effects. Here, we investigated the effects and molecular mechanism of esculin on Lipopolysaccharide/D-Galactosamine (LPS/D-Gal)-induced acute liver injury. A mouse model for acute liver injury was induced by intraperitoneal injection with D-Gal and LPS, and was assessed by histology, and serum transaminase analyses. The results showed that esculin significantly reduced the pathological symptoms of acute liver injury, as well as serum AST and ALT levels. LPS/D-Gal-induced liver myeloperoxidase (MPO) activity and malondialdehyde (MDA) content were also suppressed by esculin. Furthermore, LPS/D-Gal-induced liver tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) production were attenuated by esculin. Our data demonstrate that esculin can inhibit nuclear factor kappa B (NF-kappaB) activation as well as increase nuclear factor E2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) expression. In conclusion, this paper demonstrates that esculin protects liver injury induced by LPS/D-Gal via inhibiting inflammatory and oxidative responses. PMID- 30290267 TI - Endophytic entomopathogenic fungi enhance the growth of Phaseolus vulgaris L. (Fabaceae) and negatively affect the development and reproduction of Tetranychus urticae Koch (Acari: Tetranychidae). AB - Entomopathogenic fungi (EPF) have primarily been applied as an inundative approach to manage pests. However, in recent decade multifunctional role of EPF have been documented which provide multiple benefits to host plants when colonized as an endophyte. In this study five fungal isolates from the genus Beauveria (three), Isaria (one) and Lecanicillium (one) were evaluated for their ability to colonize common bean, Phaseolus vulgaris and to assess their effects in planta on plant growth promotion and possible negative effects on the two spotted spider mites, Tetranychus urticae. All the tested isolates in this study were able to endophytically colonize root, stem and even leaves of inoculated plants examined at 7 and 14 days post inoculation, indicating the systemic colonization of EPF. Colonized plants showed increased plant heights, fresh shoot and root weights compared to plants without inoculation. Survivorship of T. urticae significantly differed among the treatments with higher survival probability in control plants. Significant reduction in larval development, adult longevity and female fecundity of spider mites were observed when fed on treated plants compared to control plants. The negative effects were found to be carried over the second generation fed on fresh plants. Overall, our results show (i) the positive effects of fungal endophytes on plant growth, (ii) reduction in population growth rate and (iii) negative effects of endophytes on growth and reproduction of spider mites in successive generations. The study presents reports on the endophytic management of plant-feeding mites and highlights the possibility of utilizing entomopathogenic fungal endophytes in the integrated pest management program. PMID- 30290268 TI - Effects of Christensenella minuta lipopolysaccharide on RAW 264.7 macrophages activation. AB - Christensenella minuta (C. minuta) is a gram-negative gastrointestinal bacterium associated with weight loss. However, recent studies have shown that C. minuta might be a potential pathogen and thus limited its application in the control of obesity. Research into the genetic characteristics and pathogenicity of C. minuta remain elusive. As a major virulence factor of gram-negative bacteria, lipopolysaccharide (LPS) can induce various diseases. In this study, we report the complete genome sequence of C. minuta and have also identified some genes related to LPS biosynthesis. The structure of C. minuta LPS, detected by SDS PAGE, was different from that of Escherichia coli (E. coli) LPS. The incubation of RAW 264.7 macrophages with C. minuta LPS resulted in lower levels of cellular proliferation, phagocytosis and nuclear factor-kappa B (NF-kappaB) activation as compared to incubation with E. coli LPS. Furthermore, the expression of pro inflammatory cytokines, as well as nitric oxide and reactive oxygen species production, was induced in C. minuta LPS-treated cells but to a much lower extent than that by E. coli LPS. These findings show that C. minuta LPS acts as a weak agonist for RAW 264.7 macrophages and can only trigger a weak inflammatory response through the NF-kappaB signalling pathway. In conclusion, these results suggest that the toxicity of C. minuta LPS is significantly attenuated due to its atypical structure and weak agonist activity for RAW 264.7 macrophages.

AB - The antibacterial activity of sulfadiazine Au-PPh3, sulfadiazine Ph2P-Au-Au-PPh2, sulfamethoxazole Au-PPh3, sulfamethoxazole Ph2P-Au-Au-PPh2, sulfamethoxazole Au PPh3 were tested against Pseudomonas aeruginosa. The antibacterial activity of sulfonamide was tested against P. aeruginosa through the MIC assay, quantitative analysis of biofilm inhibition and observation of biofilm formation with fluorescence microscopy. Besides, the compounds presented remarkable inhibition of P. aeruginosa biofilm formation. Furthermore, molecular docking was performed to identify the key structural features of these compounds with the binding site of the LasR receptor. PMID- 30290270 TI - Single-copy expression of an amyotrophic lateral sclerosis-linked TDP-43 mutation (M337V) in BAC transgenic mice leads to altered stress granule dynamics and progressive motor dysfunction. AB - Mutations in the gene encoding the RNA-binding protein TDP-43 cause amyotrophic lateral sclerosis (ALS), clinically and pathologically indistinguishable from the majority of 'sporadic' cases of ALS, establishing altered TDP-43 function and distribution as a primary mechanism of neurodegeneration. Transgenic mouse models in which TDP-43 is overexpressed only partially recapitulate the key cellular pathology of human ALS, but may also lead to non-specific toxicity. To avoid the potentially confounding effects of overexpression, and to maintain regulated spatio-temporal and cell-specific expression, we generated mice in which an 80 kb genomic fragment containing the intact human TDP-43 locus (either TDP-43WT or TDP 43M337V) and its regulatory regions was integrated into the Rosa26 (Gt(ROSA26)Sor) locus in a single copy. At 3 months of age, TDP-43M337V mice are phenotypically normal but by around 6 months develop progressive motor function deficits associated with loss of neuromuscular junction integrity, leading to a reduced lifespan. RNA sequencing shows that widespread mis-splicing is absent prior to the development of a motor phenotype, though differential expression analysis reveals a distinct transcriptional profile in pre-symptomatic TDP 43M337V spinal cords. Despite the presence of clear motor abnormalities, there was no evidence of TDP-43 cytoplasmic aggregation in vivo at any timepoint. In primary embryonic spinal motor neurons and in embryonic stem cell (ESC)-derived motor neurons, mutant TDP-43 undergoes cytoplasmic mislocalisation, and is associated with altered stress granule assembly and dynamics. Overall, this mouse model provides evidence that ALS may arise through acquired TDP-43 toxicity associated with defective stress granule function. The normal phenotype until 6 months of age can facilitate the study of early pathways underlying ALS. PMID- 30290271 TI - Wwox deletion leads to reduced GABA-ergic inhibitory interneuron numbers and activation of microglia and astrocytes in mouse hippocampus. AB - The association of WW domain-containing oxidoreductase WWOX gene loss of function with central nervous system (CNS) related pathologies is well documented. These include spinocerebellar ataxia, epilepsy and mental retardation (SCAR12, OMIM: 614322) and early infantile epileptic encephalopathy (EIEE28, OMIM: 616211) syndromes. However, there is complete lack of understanding of the pathophysiological mechanisms at play. In this study, using a Wwox knockout (Wwox KO) mouse model (2 weeks old, both sexes) and stereological studies we observe that Wwox deletion leads to a significant reduction in the number of hippocampal GABA-ergic (gamma-aminobutyric acid) interneurons. Wwox KO mice displayed significantly reduced numbers of calcium-binding protein parvalbumin (PV) and neuropeptide Y (NPY) expressing interneurons in different subfields of the hippocampus in comparison to Wwox wild-type (WT) mice. We also detected decreased levels of Glutamic Acid Decarboxylase protein isoforms GAD65/67 expression in Wwox null hippocampi suggesting lower levels of GABA synthesis. In addition, Wwox deficiency was associated with signs of neuroinflammation such as evidence of activated microglia, astrogliosis, and overexpression of inflammatory cytokines Tnf-a and Il6. We also performed comparative transcriptome-wide expression analyses of neural stem cells grown as neurospheres from hippocampi of Wwox KO and WT mice thus identifying 283 genes significantly dysregulated in their expression. Functional annotation of transcriptome profiling differences identified 'neurological disease' and 'CNS development related functions' to be significantly enriched. Several epilepsy-related genes were found differentially expressed in Wwox KO neurospheres. This study provides the first genotype phenotype observations as well as potential mechanistic clues associated with Wwox loss of function in the brain. PMID- 30290272 TI - Multiple recycling routes: Canonical vs. non-canonical mitophagy in the heart. AB - The heart is composed of cardiomyocytes that require large amounts of energy to sustain contraction. Mitochondria are distinctive organelles of bacterial origin that generate most of the energy for the heart via oxidative phosphorylation. To ensure a healthy population of mitochondria that efficiently produce ATP, myocytes quickly eliminate any unhealthy or unwanted mitochondria via a process known as mitochondrial autophagy, or mitophagy. It is especially important to selectively remove damaged or aged mitochondria since they can become excessive producers of reactive oxygen species and release pro-death proteins. Because this is such a crucial cellular process, cells have several mechanisms in place to deal with potentially harmful mitochondria. Here, we review the various pathways identified to date and how they are regulated. We also discuss the importance of these canonical and non-canonical pathways in the heart and their link to cardiovascular health, disease and aging.

AB - Parkinson's disease (PD) is a common neurodegenerative disease which usually associates with neuroinflammation. The main pathological characteristics of PD are dopaminergic neurons death and the presence of Lewy bodies which are composed of aggregated alpha-synuclein (alpha-Syn). Truncated forms of alpha-Syn are found in the brain of PD patients, and account for 10-30% of total synuclein in Lewy bodies. Caspase-1, which plays an important role in neuroinflammation, cleaves full-length alpha-Syn (alpha-Syn FL) to generate a C-terminus 19-residues truncated alpha-Syn (alpha-Syn121). However, the role of truncated alpha-Syn in the onset and/or pathogenesis of PD is unclear. Here, we used alpha-Syn121 as a model to explore its aggregation, membrane disruption and cytotoxicity properties. Compared with alpha-Syn FL, alpha-Syn121 aggregated at an accelerated rate, and formed amorphous aggregates rich in random coil structures rather than beta-sheet-rich linear fibrils formed by alpha-Syn FL. Importantly, higher cytotoxicity with lower membrane disruption capacity was found for alpha-Syn121 aggregates. Furthermore, alpha-Syn121 aggregates could activate the apoptosis signaling pathway and stimulate the caspase-1-mediated cleavage of alpha-Syn FL to generate alpha-Syn121, which as a result leading to increased levels of endogenous alpha-Syn121 and intracellular S129 phosphorylated alpha-Syn inclusions. Together, our data suggests a hidden vicious cycle in PD that alpha Syn121 rapidly forms amorphous aggregates, which activate caspase-1 to cleave alpha-Syn FL and generate more alpha-Syn121, and this cycle may contribute to the onset and/or pathogenesis of PD. PMID- 30290274 TI - Asthma alleviates obesity in males through regulating metabolism and energy expenditure. AB - Many epidemiological studies suggested a correlation between obesity and asthma. However, little is known about the molecular details explaining this correlation. Here, we show that asthma decreased body weight of asthmatic male mice fed with high fat diet via increasing energy expenditure and insulin sensitivity. The increase of energy expenditure was mainly due to upregulation of pAMPK and Sirt1. The activation of AMPK/Sirt1/PGC1alpha signaling promoted the expression of the thermogenic genes like ucp1, PRDM16, cidea, Elovl3, PPARalpha, which occurred in brown adipocyte tissue and subcutaneous white adipose tissue. Besides, by activating IL33/ILC2/AAMac pathway in subcutaneous white adipose tissue, asthma promoted subcutaneous white adipose tissue into beige fat. In addition, insulin sensitivity was improved in the asthmatic male mice by decreasing the expression of G6Pase in the liver, which was recapitulated in HepG2. In human, we found that Body Mass Index (BMI) and waist circumference were significantly lower in males suffering asthma compared with the control in the National Health and Nutrition Examination Survey (NHANES) cohort. These data together suggest asthma in males decreases obesity by improving the metabolism function of brown and subcutaneous adipose tissue, and decreasing insulin resistant in the liver. PMID- 30290275 TI - A web-based program to improve treatment adherence in patients with type 2 diabetes: Development and study protocol. AB - BACKGROUND: Many patients with type 2 diabetes mellitus (T2DM) sub-optimally adhere to core treatment recommendations, such as healthy diets, sufficient physical activity and pharmacological support. This paper describes the development of the web-based computer-tailored program My Diabetes Profile (MDP), incorporating identified success factors of web-based interventions, and the protocol for testing the effectiveness of this program in a randomized multicentre trial. METHODS: Formative research - including the input of a program committee, qualitative and quantitative studies with patients and health professionals and a literature search - yielded input for the development of the MDP program. MDP provides video and text tailored advice, based on determinants and salient beliefs derived from the I-Change Model, on decreasing unhealthy snack intake, increasing physical activity, and improving adherence to both oral blood glucose lowering drugs and self-administered insulin therapy. Patients with T2DM recruited by practice nurses and diabetes nurses across the Netherlands fill in online questionnaires at baseline and six-months follow-up. Participants are randomized on patient level to the intervention group (access to the MDP program) or control group (receiving care as usual). DISCUSSION: The formative research using co-creation principles proved essential in the development of the MDP program and involved various disciplines in T2DM management including target group representatives. Co-creation revealed clearly that patients needed short and attractive messages. Consequently, a mix of video and short text messages were chosen for the ultimate program format. Pilot testing was useful to further shape the program to needs of patients and professionals.

PMID- 30290276 TI - Mobile health intervention for self-management of adolescent chronic pain (WebMAP mobile): Protocol for a hybrid effectiveness-implementation cluster randomized controlled trial. AB - INTRODUCTION: Approximately 5-8% of children report severe chronic pain and disability. Although evidence supports pain-self management as effective for reducing pain and disability, most youth do not have access to psychological intervention. Our prior studies demonstrate that an existing internet-delivered pain self-management program (WebMAP) can reduce barriers to care, is feasible, acceptable, and is effective in reducing pain-related disability in youth with chronic pain. The current trial seeks to: 1) determine the effectiveness of a mobile app version of WebMAP for improving patient pain-related outcomes, and 2) evaluate a novel implementation strategy to maximize the public health impact of the intervention including the determination of adoption, reach, and sustainability of WebMAP in specialty clinics serving children with chronic pain in the United States. METHODS: This hybrid effectiveness-implementation cluster randomized controlled trial employs a stepped wedge design in which the WebMAP mobile intervention is sequentially implemented in 8 specialty pain clinics following a usual care period. This trial aims to enroll a minimum of 120 youth (ages 10-17) who have chronic pain. Outcome analyses will determine effectiveness of treatment on adolescent pain-related outcomes as well as public health impact via reach, adoption, implementation, and maintenance. CONCLUSIONS: This trial examines an innovative approach to evaluate a technology-delivered pain self management program for youth with chronic pain. Findings are expected to yield a strategic approach for delivering a digital pain management program for youth with chronic pain that can be sustained in clinical settings.

AB - BACKGROUND: Real-time video communication technology (e.g. Skype) may be an effective mode for delivering smoking cessation treatment to regional and remote residents. This randomised trial examines the effectiveness of real-time video counselling compared to: 1) telephone counselling; and 2) written materials (control) in achieving smoking abstinence in regional and remote residents. DESIGN: A three-arm, parallel group, randomised trial will be conducted with smokers residing in regional and remote areas of New South Wales, Australia. Potential participants will complete an online screening survey and if eligible an online baseline survey. Participants will be randomly allocated into: 1) real time video counselling; 2) telephone counselling; or 3) written materials (control). In the video counselling intervention an advisor will deliver up to six video sessions (e.g. via Skype) to participants. Those who nominate a quit date within a month during the initial video session will be offered sessions on the quit date, 3-, 7-, 14- and 30-days after the quit date. Those not ready to set a quit date within a month during the initial video session will be offered sessions 2-, 4- and 6-weeks later. Other than delivery mode, the video counselling and telephone counselling will be identical in content and callback schedules. Control group participants will be mailed one-off written materials. Follow-up surveys will occur at 4-months, 7-months and 13-months post-baseline. The primary outcome will be 7-day point prevalence abstinence at 13-months post baseline. DISCUSSION: Real-time video counselling may be an effective strategy for smoking cessation that could be integrated into quitlines globally. PMID- 30290278 TI - Tardiness of starts of surgical cases is not substantively greater when the preceding surgeon in an operating room is of a different versus the same specialty. AB - STUDY OBJECTIVE: Switching from one specialty to another increases mean turnover times (i.e., interval between the exit and entrance of consecutive patients in an operating room [OR]). We estimate the effect on the mean tardiness of to-follow surgeons from following another surgeon of a different versus same specialty. Tardiness of a case's start time refers to the number of minutes the patient enters the OR later than scheduled; tardiness is 0 min if the patient enters early. Tardiness cause surgeon waiting. There are multiple causes of tardiness, but, most often, the preceding case(s) took longer than estimated. DESIGN: 10 year historical cohort study with all surgical cases performed during regular workdays. SETTING: Large teaching hospital. MEASUREMENTS: Estimated OR end times were calculated using a Bayesian method. Because tardiness is influenced by the estimated case start time (i.e., later starting cases have greater tardiness), tardiness values were adjusted to a 12 noon start time for the 2nd surgeon. MAIN RESULTS: The cases of to-follow surgeons in ORs had mean tardiness of 45.1 (SE 0.6) min. When the to-follow surgeon in the OR was of a different versus the same specialty from the first surgeon, the mean turnover time was 7.3 (0.4) min longer (P < 0.00001). However, the mean tardiness was not significantly affected (0.1 min, 95% confidence interval [CI] -2.7 to 3.0 min; P = 0.93). In comparison, if one or more of the preceding cases in an OR was an add-on case, the increase in mean tardiness was 35 min (95% CI 28 to 43 min; P < 0.00001). CONCLUSIONS: OR managers can assure surgeons with afternoon starts that following a surgeon of a different specialty generally will not increase their waiting time. Case scheduling should focus on reducing over-utilized OR time and thus the hours that anesthesiologists and nurses work late.

PMID- 30290280 TI - Synthesis, molecular docking and inhibition studies of novel 3-N-aryl substituted 2-heteroarylchromones targeting microtubule affinity regulating kinase 4 inhibitors. AB - A series of 3-N-aryl substituted-2-heteroarylchromones was efficiently synthesized via Pd-mediated oxidative coupling under the influence of hetero atoms neighboring group participation. Synthesized molecules were evaluated against human microtubule affinity regulating kinase 4 (MARK4) enzyme inhibitors, a recently identified anti-cancer drug target. Among 21 synthesized molecules, compounds 2, 3, and 14 exhibited excellent in vitro inhibitory effect against MARK4 with IC50 value (50% of ATPase activity) at 2.12 +/- 0.22 MUM, 1.98 +/- 0.34 MUM and 5.56 +/- 0.42 MUM respectively. The fluorescence binding and dot blot assay of these compounds were found in MUM range, indicating a better binding affinity. In vitro study of these compounds against cancerous cells (MCF 7 and HepG2) inhibited the cell viability, induced apoptosis and lowered the tau phosphorylation. Cell viability studies of compounds 2, 3, and 14 showed inhibition of cancerous cells growth with IC50 values of 3.22 +/- 0.42, 4.32 +/- 0.23 MUM and 16.22 +/- 1.33 MUM for human breast cancer cells (MCF-7) and 6.45 +/ 1.12, 5.22 +/- 0.72 MUM and 19.12 +/- 1.43 MUM for human liver carcinoma cells (HepG2) respectively. ROS quantification of these compounds showed oxidative stress to cancerous cells and molecular docking study showed hydrogen bonding, charge or polar and van der Waals interactions with the active site residues of MARK4. Owning to high binding fit nicely in the active site, offering the possibilities to be used as novel therapeutic molecules in the drug discovery against MARK4-related diseases. PMID- 30290281 TI - Is recovery from ankle sprains negatively affected by obesity? AB - OBJECTIVE: Ankle sprains are common injuries that may lead to long-term morbidity. Individuals with obesity are at increased risk for ankle sprains; however, prognostic associations between body mass index (BMI) and recovery are less well understood. This study investigated whether BMI status affects recovery from ankle sprains. METHODS: We included individuals>=16 years old with grade 1 or 2 ankle sprains who sought emergency department treatment in Kingston, Ontario, Canada. Height in centimeters and weight in kilograms were measured at baseline by using a height rod and a standard medical column scale, respectively. BMI was calculated and categorized as non-overweight,<25.0kg/m2; overweight, 25.0 29.9kg/m2; and obese,>=30kg/m2. Recovery was assessed at 1, 3 and 6 months post injury by the Foot and Ankle Outcome Score (FAOS). Continuous FAOS and binary recovery status were compared by BMI group at each assessment using a repeated measures linear mixed effects model and logistic regression, respectively. RESULTS: In total, 504 individuals were recruited and 6-month follow-up data were collected for 80%. We observed no significant differences in recovery at 1 and 3 months post-injury. At 6 months, between 53% and 66% of the participants were considered to have recovered according to the FAOS. The mean difference in unadjusted FAOS between participants classified as obese and non-overweight was 23.02 (95% confidence interval, -38.99 to -7.05) but decreased after adjusting for confounders. The odds ratio for recovery was 0.60 (0.37-0.97) before adjustment and 0.74 (0.43-1.29) after adjustment. Six-month recovery was significantly lower for participants with obesity than non-overweight participants on the FAOS Pain and Function in Daily Living subscales but were not clinically meaningful. CONCLUSIONS: All BMI groups showed improvements from ankle sprain over time. However, at 6 months, a sizeable proportion of the participants had not fully recovered particularly among individuals classified as obese. The findings suggest that individuals with obesity may benefit from specialized interventions focused on symptom management and functional activity. PMID- 30290282 TI - Orthopaedic surgery for patients with central nervous system lesions: Concepts and techniques. AB - Since ancient times, the aim of orthopedic surgery has been to correct limb and joint deformities, including those resulting from central nervous system lesions. Recent developments in the treatment of spasticity have led to changes in concepts and management strategies. The increase in life expectancy has increased the functional needs of patients. Orthopedic surgery, along with treatments for spasticity, improves the functional capacity of patients with neuro-orthopaedic disorders, improving their autonomy. In this paper, we describe key moments in the history of orthopedic surgery regarding the treatment of patients with central nervous system lesions, from poliomyelitis to stroke-related hemiplegia, from the limbs to the spine, and from contractures to heterotopic ossification. A synthesis of the current surgical techniques is then provided, and the importance of multidisciplinary evaluation and management is highlighted, along with indications for medical, rehabilitation and surgical treatments and their combinations. We explain why it is essential to consider patients' expectations and to set achievable goals, particularly before surgery, which is by nature irreversible. More recently, specialized surgical teams have begun to favor the use of soft-tissue techniques over bony and joint procedures, except for spinal disorders. We highlight that orthopedic surgery is no longer the end-point of treatment. For example, lengthening a contractured muscle improves the balance around a joint, improving mobility and stability but may be only part of the problem. Further medical treatment and rehabilitation, or additional surgery, are often necessary to continue to improve the function of the limb. Despite the recognized effectiveness of orthopedic surgery for neuro-orthopedic disorders, few studies have formally evaluated them. Hence, there is a need for research to provide evidence to support orthopedic surgery for treating neuro-orthopedic disorders. PMID- 30290283 TI - Physical activity level and association with behavioral factors in knee osteoarthritis. AB - BACKGROUND: The effects of physical activity (PA) in disease prevention and therapy have well-known effects on lower-limb osteoarthritis (OA), decreasing pain and improving function. OBJECTIVE: We aimed to describe the level and factors affecting PA practices of people with knee OA. DESIGN: Prospective epidemiological study. SETTING: In all, 548 people with knee OA were interviewed by use of self-administered anonymous questionnaires. MAIN OUTCOME MEASUREMENT: The main outcome was physical activity level evaluated by the International physical activity questionnaire (IPAQ) (short version). Secondary outcomes included sociodemographic and clinical data, comorbidities, and barriers to and facilitators of practicing regular PA evaluated by 24 specific elements. RESULTS: The mean (SD) age of the study population was 67.6 (7.9) years; 73.9% were women and 30.9% had obesity (mean [SD] body mass index [BMI] 28.2 [5.7] kg/m2). Multi joint OA affected 92% of the population, and 71.6% had comorbidities. The mean (SD) visual analog scale score for pain intensity was 4.5/10 (2.5), which was 51.4% better than the patient acceptable symptom state (PASS). The mean (SD) Western Ontario and McMaster Universities Osteoarthritis Index function score was 36.6/100 (20.7), which was 57.5% better than the PASS. In total, 67% of patients used analgesics, half of them at least once a week. According to the IPAQ, 42.6% of patients reported high, 38.6% moderate, and 18.8% low PA level; the median IPAQ total activity score was 2628 metabolic equivalent of task (MET)-min/week and time spent sitting was 257.1min/day. Only one third of participants received non-pharmacological treatment corresponding to the latest recommendations. Variables significantly related to inactive or minimally active PA levels were BMI (P=0.0294), sex (P=0.0008), and biomedical barriers, related to self-efficacy (P=0.0118). CONCLUSIONS: The OA study population was less active, more sedentary, and had more comorbidities and more barriers to PA practice than the overall population. PMID- 30290284 TI - Informal caregiving and diurnal patterns of salivary cortisol: Results from the Whitehall II cohort study. AB - The objective was to investigate the relationship between various aspects of informal caregiving and diurnal patterns of salivary cortisol, with special attention to the moderating effect of sex and work status. The study population was composed of 3727 men and women from the British Whitehall II study. Salivary cortisol was measured six times during a weekday. Aspects of caregiving included the relationship of caregiver to recipient, weekly hours of caregiving, and length of caregiving. Diurnal cortisol profiles were assessed using the cortisol awakening response (CAR) and diurnal cortisol slopes. Results showed that men, but not women, providing informal care had a blunted CAR compared with non caregivers (PInteraction = 0.03). Furthermore, we found a dose-response relationship showing that more weekly hours of informal care was associated with a more blunted CAR for men (Ptrend = 0.03). Also, the blunted CAR for men was especially pronounced in short-term caregivers and those in paid work. In women, the steepest cortisol slope was seen among those in paid work who provided informal care (PInteraction = 0.01). To conclude, we found different cortisol profiles in male and female informal caregivers. Male caregivers had a blunted CAR, which has previously been associated with chronic stress and burnout. Future research should investigate whether results are generalizable beyond UK citizens with a working history in the civil service. PMID- 30290285 TI - Parasitaemia and parasitic load are limited targets of the aetiological treatment to control the progression of cardiac fibrosis and chronic cardiomyopathy in Trypanosoma cruzi-infected dogs. AB - It is still unclear whether the progression of acute to chronic Chagas cardiomyopathy is predominantly associated with the limited efficacy of aetiological chemotherapy, or with the pharmacological resistance profiles and pathogenicity of specific Trypanosoma cruzi strains. Thus, we tested the hypothesis that parasitic load could be a limited target of aetiological chemotherapy to prevent chronic cardiomyopathy in dogs infected by different T. cruzi strains. Animals were infected with benznidazole-susceptible (Berenice-78) and -resistant (VL-10 and AAS) strains of T. cruzi. A quantitative real-time PCR strategy was developed to comparatively quantify the parasite load of the three different strains using a single standard curve. For dogs infected with the VL-10 strain, benznidazole treatment reduced cardiac parasitism during the acute phase of infection. However, similar parasite load and collagen deposition were detected in the myocardium of treated and untreated animals in the chronic phase of the infection. In animals infected with the AAS strain, benznidazole reduced parasite load, myocarditis and type III collagen deposition in the acute phase. However, increased type III collagen deposition was verified in the chronic phase. Dogs infected with the Berenice-78 strain showed a parasitological cure and no evidence of myocardial fibrosis. Parasitic load and cardiac fibrosis presented no correlation in acute or chronic phases of T. cruzi infection. Our findings in a canine model of Chagas disease suggest that parasite burden is a limited predictor for disease progression after treatment and show that benznidazole, although not inducing parasitological cure, is able to prevent total fibrosis in the early stages of infection, as well as complete prevention of cardiac damage when it eliminates parasites at the onset of infection. PMID- 30290286 TI - Network abnormalities in generalized anxiety pervade beyond the amygdala-pre frontal cortex circuit: Insights from graph theory. AB - Generalized anxiety disorder (GAD) has excessive anxiety and uncontrollable worry as core symptoms. Abnormal cerebral functioning underpins the expression and perhaps pathogenesis of GAD:. Studies implicate impaired communication between the amygdala and the pre-frontal cortex (PFC). Our aim was to longitudinally investigate whether such network abnormalities are spatially restricted to this circuit or if the integrity of functional brain networks is globally disrupted in GAD. We acquired resting-state functional magnetic resonance imaging data from 16 GAD patients and 16 matched controls at baseline and after 1 year. Using network modeling and graph-theory, whole-brain connectivity was characterized from local and global perspectives. Overall lower global efficiency, indicating sub-optimal brain-wide organization and integration, was present in patients with GAD compared to controls. The amygdala and midline cortices showed higher betweenness centrality, reflecting functional dominance of these brain structures. Third, lower betweenness centrality and lower degree emerged for PFC, suggesting weakened inhibitory control. Overall, network organization showed impairments consistent with neurobiological models of GAD (involving amygdala, PFC, and cingulate cortex) and further pointed to an involvement of temporal regions. Such impairments tended to progress over time and predict anxiety symptoms. A graph analytic approach represents a powerful approach to deepen our understanding of GAD. PMID- 30290287 TI - MYC Amplification as a Potential Mechanism of Primary Resistance to Crizotinib in ALK-Rearranged Non-Small Cell Lung Cancer: A Brief Report. AB - INTRODUCTION: Translocations of the anaplastic lymphoma kinase (ALK) can be effectively targeted in advanced non-small cell lung cancer by ALK-TKI inhibitors including Crizotinib. However, the development of acquired resistance often limits the duration of these therapies. While several mechanisms of secondary resistance have been already identified, little is known about molecular determinants of primary resistance. In our brief report we investigated the tumor molecular profile of a patient who failed to respond to Crizotinib. METHODS: Fluorescence in situ hybridization (FISH) and next-generation sequencing (NGS) were run on tumor specimen as well as search and characterization of circulating tumor cells (CTCs) in the blood. Confirmation of clinical findings was achieved using a translational cell-line in vitro model. RESULTS: We identified the amplification of MYC as a potential new mechanism of primary resistance to ALK inhibition. Human EML4-ALK rearranged cells infected with a lentiviral vector carrying full-length human MYC cDNA were treated in vitro with crizotinib and alectinib. Overexpression of MYC overexpression was associated with a reduced sensitivity to both ALK-inhibitors. MYC-overexpressing clones displayed also increased levels of both cyclin D and E and their growth was reduced by using Cdk4/6 inhibitors such as Palbociclib. CONCLUSIONS: We postulate that the MYC gene may be implicated in the mechanism of primary resistance to ALK inhibitors. We also suggest potential MYC-directed inhibition strategies to overcome primary resistance in advanced ALK-rearranged NSCLC. PMID- 30290288 TI - Political cycles in physician employment: A case of Japanese local public hospitals. AB - A shortage of physicians in local public hospitals is often a heated political issue. When local politicians have the authority to intervene in the management of a public hospital, they may increase the employment of physicians during election years in order to alleviate the shortage. We test this hypothesis empirically using a census of city hospitals in Japan from 2002 to 2011 (N = 4583). Our results support the hypothesis that the number of physicians increases in election years. This effect is stronger in cities with a greater population of elderly residents. We also find that physicians tend to come from university hospitals in the same region. Overall, this paper provides direct evidence of political intervention on physician employment. PMID- 30290289 TI - Design and baseline characteristics of the eValuation of ERTugliflozin effIcacy and Safety CardioVascular outcomes trial (VERTIS-CV). AB - BACKGROUND: Ertugliflozin is an inhibitor of sodium-glucose co-transporter-2 (SGLT2), approved in the United States and European Union to improve glycemic control in adults with type 2 diabetes mellitus (T2DM). The VERTIS cardiovascular (CV) outcomes trial (NCT01986881) has a primary objective to demonstrate non inferiority of ertugliflozin versus placebo on major adverse CV events: time to the first event of CV death, nonfatal myocardial infarction, or nonfatal stroke. Secondary objectives are to demonstrate superiority of ertugliflozin versus placebo on time to: 1) the composite outcome of CV death or hospitalization for heart failure (HF); 2) CV death; and 3) the composite outcome of renal death, dialysis/transplant, or doubling of serum creatinine from baseline. METHODS: Patients >=40 years old with T2DM (HbA1c 7.0-10.5%) and established atherosclerotic cardiovascular disease (ASCVD) of the coronary, cerebral, and/or peripheral arterial systems, were randomized 1:1:1 to once daily double-blind placebo, ertugliflozin 5 mg or 15 mg added to existing therapy. RESULTS: 8246 patients were randomized and 8238 received at least 1 dose of investigational product. Mean age was 64.4 years, 11.0% were >=75 years old, and mean diabetes duration was 12.9 years with screening HbA1c of 8.3%. At entry, coronary artery disease, cerebrovascular disease, and peripheral arterial disease were present in 76.3%, 23.1%, and 18.8% of patients, respectively. HF was present in 23.1%, and Stage 3 kidney disease in 21.6% of patients. CONCLUSION: The results from the VERTIS-CV trial will define the CV and renal safety and efficacy of ertugliflozin in patients with T2DM and ASCVD.

PMID- 30290291 TI - Opioid and cocaine use among primary care patients on buprenorphine-Self-report and urine drug tests. AB - BACKGROUND: Urine drug tests (UDTs) are recommended to monitor patients treated for opioid use disorder in primary care. The aims are to (1) estimate the frequency of self-report and UDT results of opioid and cocaine use and (2) evaluate the association between treatment time with non-disclosure of opioid or cocaine use and having a positive UDT. METHODS: We conducted a retrospective review of patients enrolled in a primary care-based buprenorphine program between January 2011-April 2013. We describe three clinical visits types: no disclosure of opioid/cocaine use and positive UDT; disclosure of opioid or cocaine use and a negative or positive UDT; and no disclosure of opioid or cocaine use and a negative UDT. We fit generalized estimating equations logistic regression models to evaluate whether treatment time is associated with non-disclosure of opioids or cocaine use and a positive UDT. RESULTS: Among all UDT results (n = 1755) from 130 patients, 10% were positive for illicit opioids and 4% for cocaine. Among UDTs with illicit opioid or cocaine positive results, in 57% and 76% of these scenarios, the patient did not disclose. The odds of non-disclosure and having a positive UDT was higher in the first 180 days for opioids and 90 days for cocaine. CONCLUSION: Among primary care patients treated with buprenorphine, a small but substantial percentage of UDTs were cocaine or opioid positive. As treatment time increased, non-disclosure was less common but persisted even after six months. Among primary care patients treated with buprenorphine, UDTs contribute information to optimize clinical care. PMID- 30290292 TI - A combined experimental and density functional theory investigation of the hydrogen bonding of 2-cyclohexen-1-one and 3-methyl- 2-cyclohexen-1-one in solvents. AB - Hydrogen bonding is a weak chemical interaction widely existed in the variety of organic and biological molecules. As an important structural motif of pyrimidine bases, the solvent effect of the hydrogen bonding of 2-cyclohexen-1-one (CHO) and 3-methyl- 2-cyclohexen-1-one (3MCHO) and its effect on the frequency shift of the CO stretching mode were investigated by using the FT-Raman and UV absorption spectra and density functional theory calculations. The electronic transitions associated with the UV absorptions in different solvents were calculated at B3LYP TD/6-31++G(d,p) level of theory and employing SCIPCM solvent model. The vibrational spectra of CHO and 3MCHO were assigned on the basis of the FT-Raman spectra in neat liquid and different solvents, the calculated vibrational spectra of monomer and CHO dimers, and the concentration dependent experiments of the band pair intensities. Hydrogen bonding energies of CHO-(H2O)n (n = 1,2) clusters were predicted. The results reveal that the CHO-(H2O)2 cluster and CHO monomer are respectively the major source of spectral observation in water and cyclohexane, while CHO dimmer and CHO monomer coexist in acetonitrile. The difference in the frequency of the nuC=O stretching mode between 3MCHO monomer and CHO monomer in cyclohexane were explored. PMID- 30290293 TI - Sex determination of silkworm pupae using VIS-NIR hyperspectral imaging combined with chemometrics. AB - To explore an accurate and non-destructive method to discriminate the sex of silkworm pupae, the visible and near-infrared (VIS-NIR) hyperspectral imaging (HSI) technique was employed in this paper. First, a total of 520 hyperspectral images of silkworm pupae of four species were captured using a push-broom HSI system in the spectral region of 363 nm to 1026 nm and then calibrated for reflectance. The mean spectral data were extracted from the region of interest (ROI). Second, five optimal wavelengths (403, 440, 505, 533, 721 nm) were selected by successive projection algorithm (SPA). Then gray-level co-occurrence matrix (GLCM) analysis was implemented on the 500 nm image. Finally, support vector machine (SVM) and radial basis function and neutral network (RBF-NN) models were established based on full spectra, textural data, spectral data and fusion data, respectively. The SVM and RBF-NN models using fusion data reached the most satisfactory performance with a high correct classification rate of 98.75%. Furthermore, the built SVM model based on fusion data could be promoted to identify the sex of another two species of silkworm pupae with accuracy of 97% and 96%, indicating that HSI technology can be served as a new method to differentiate the sex of silkworm pupae. PMID- 30290294 TI - Interferon gamma and interleukin 8 gene polymorphisms in patients with hepatitis C virus related oral lichen planus. AB - OBJECTIVES: This study aimed to determine the association of rs2430561 and rs4073 polymorphisms in the Interferon gamma (IFN-?) and Interleukin 8 (IL-8) genes, respectively, with hepatitis C virus-related oral lichen planus and disease severity. DESIGN: This is a case-control study. 60 subjects were equally divided into patients with and without oral lichen planus. They were further subdivided into hepatitis C virus seropositive and seronegative patients. All patients were genotyped for IFN-gamma rs2430561 thymine to adenine (T > A) and IL-8 rs4073 adenine to thymine (A > T) polymorphisms. All patients with oral lichen planus had their lesions measured and documented using the Escudier scoring system. RESULTS: Disease activity was significantly higher in the "oral lichen planus/hepatitis C virus-positive" patients than in the "oral lichen planus/hepatitis C virus-negative" patients (P = 0.003). IFN-gamma rs2430561 T > A and IL-8 rs4073 A > T genotypes and allele frequencies were not associated with the oral lichen planus group or the normal group. Stratification of the two groups into HCV and non-HCV-infected patients or into erosive and non-erosive types revealed no significant associations. The "A-allele-containing" genotypes of IL-8 rs4073 A > T were significantly more prevalent in the patients with oral lichen planus than in those without. CONCLUSION: Hepatitis C virus infection is associated with the development of erosive oral lichen planus. The A-allele of IL 8 rs4073 A > T may have a role in the development and progression of oral lichen planus. PMID- 30290295 TI - Erythromycin sensitivity across different taxa of marine phytoplankton. A novel approach to sensitivity of microalgae and the evolutionary history of the 23S gene. AB - Erythromycin has been recorded in coastal waters and could pose a severe threat to marine microbial life. Macrolides such as erythromycin may affect microalgae by inhibiting the pathways involved in protein synthesis. Toxicological testing of microalgae has proven to be a useful tool for the risk assessment of a substance affecting phytoplankton. Due to the controversial results concerning the sensitivity of microalgal species to erythromycin found in the literature, the goals of this work were, initially, to assess the erythromycin sensitivity of different species of marine microalgae from different and representative taxonomic groups; and, secondly, to examine whether the sensitivity to erythromycin could be explained by the differences in the phylogenetic evolution. We chose eight species: two green algae, four heterokonts, one haptophyte and one dinoflagellate, which were then exposed to erythromycin (0.1 to 10 mg L-1). Our results showed a wide range of sensitivities indicating that the biology of each species was primarily responsible for the variation observed. To test the second objective, we contrasted different ecotoxicological endpoints (growth, cellular properties and status of the photosynthetic apparatus) with the phylogenetic distribution [eukaryotic host (concatenated nuclear tree), evolutionary history of the chloroplast (16S tree), efficiency and repair of photosystem II (psbA tree), and the binding site of erythromycin (23S tree)] of the species. We found that the growth inhibition of microalgae as a toxicological endpoint was the endpoint best explained by the topology of the 23S rRNA gene tree when it was modelled following a non-stationary evolutionary process.

AB - Most recent studies on Janus particles have concentrated on amphiphilic Janus particles. Herein, a facile and efficient method based on polymerization-induced phase separation is presented to fabricate Janus particles with different morphologies. Theses novel hydrophilic Janus particles with two distinct hydrophilic domains have been prepared by combination of distillation precipitation polymerization (DPP) and seeded emulsion polymerization. Crosslinked poly(2-hydroxyehtyl methacrylate) (PHEMA) cores were synthesized via DPP and used as seed particles. Also, methacrylic acid (MAA) was used as second hydrophilic monomer. Effect of feeding approach, and reaction medium were investigated on the morphology of fabricated composite particles. Different morphologies such as cauliflower-like, dumbbell-like, and core-shell toward cauliflower-like structures were obtained by varying feeding approach and polymerization medium. The morphology of resultant particles was observed by means of FE-SEM and TEM images and their particle sizes were confirmed by DLS. Fabricated composite particles were used to simultaneously carry both DOX and ibuprofen. Drug release studies showed that Janus particles can be used in loading and release of two drugs simultaneously. However, release behaviors of DOX and ibuprofen were different at different pH values. Also, release behavior was significantly affected by the structure of composite particles. PMID- 30290297 TI - ECG authentication system design incorporating a convolutional neural network and generalized S-Transformation. AB - Electrocardiogram (ECG) is gaining increased attention as a biometric method in a wide range of applications, such as access control and security/privacy requirements. The majority of reported investigations using the ECG biometric method are usually based on fiducial or nonfiducial methods, which are always accompanied by a series of issues, such as locating fiducial points accurately is difficult, feature selection is subjective, and classifiers are limited by the quantity and structure of data. This paper proposes a new biometric authentication system for human identification that uses ECG signals as a biometric trait and integrates a generalized S-transformation and a convolutional neural network (CNN). Specifically, we first introduce a blind segmentation strategy that effectively avoids difficult data-specific heartbeat recognition and segmentation techniques. Then, a generalized S-transformation is performed on the blind signal-processed ECG signal, capturing the ECG trajectory at each time point in the frequency domain. Next, the getframe technology is used to capture an image of the ECG trajectories and convert the one-dimensional signal to a two dimensional image, which serves as the input layer of the CNN, thus fully reflecting the changing trend in the ECG signal spectrum characteristics over a continuous period. Finally, the CNN is used for automatic discriminative feature learning and representations, which avoids a tedious feature extraction algorithm. In addition, considering the possible impact of ECG signals with different signal behaviors on identification, experiments are performed on three ECG databases with diverse features, comprising normal individuals, atrial fibrillation patients, and a noisy database, to evaluate the effectiveness of the proposed algorithm. Promising identification rates of 99%, 98%, and 99% were achieved, respectively. Thus, our proposed ECG authentication system can be effectively used for identity recognition under various conditions. PMID- 30290298 TI - Perfusion abnormality on three-dimensional arterial spin labeling with a 3T MR system in pediatric and adolescent patients with migraine. AB - PURPOSE: Few studies have assessed the prevalence of perfusion abnormality with migraine. This study aimed to determine the prevalence and topography of perfusion abnormality on three-dimensional (3D) arterial spin labeling (ASL) and assess the correlation between perfusion abnormality and clinical data in pediatric and adolescent patients with migraine. METHODS: Forty-nine consecutive pediatric and adolescent patients with migraine were enrolled, and they underwent 3 T MRI, including 3D ASL. Perfusion abnormality on 3D ASL was qualitatively evaluated using a five-point grading system and was compared with non-ASL MR findings. In patients with perfusion abnormality, relative cerebral perfusion signal intensity (rCPS) was measured. Moreover, we compared clinical data and 3D ASL findings between patients with and those without perfusion abnormality. RESULTS: Of the 49 patients, 11 (22%) exhibited perfusion abnormality, and the occipital lobe was the most frequently involved (73%). One patient showed mild hyperperfusion (rCPS =2.474), and 10 showed hypoperfusion (mean rCPS = 0.405 +/- 0.134). There was no abnormality on non-ASL MRI, except in one case. We found statistically significant differences in the presence of aura (P < .001), motor disabilities (P = .019), confusion (P = .004), hospitalization (P = .004), between patients with and those without perfusion abnormality. CONCLUSION: In pediatric and adolescent patients with migraine, 3D ASL shows a high prevalence of perfusion abnormality, especially in the occipital lobe. Patients with perfusion abnormality tend to show the specific clinical symptoms at disease onset and need hospitalization. PMID- 30290299 TI - Factors associated with Quitline and pharmacotherapy utilisation among low socioeconomic status smokers. AB - AIMS: To examine factors associated with Quitline and pharmacotherapy utilisation in low socioeconomic status (low-SES) smokers enrolled in a smoking cessation trial. METHODS: Baseline data was used from a large-scale smoking cessation randomised controlled trial (RCT). Logistic regression models were used to examine predictors of treatment utilisation prior to entering the RCT and perceived effectiveness of past and future use. RESULTS: A total of 1047 smokers consented and prior to enrolment 92% had previously tried to quit smoking, 86% had ever used quit support, 83% had used pharmacotherapy at least once and 38% had ever utilised Quitline. For those who had used pharmacotherapies, 71% used NRT, of which 21% had used dual NRT products. In the last 12-months, 27% utilised Quitline and 50% utilised NRT. Ever use of Quitline was negatively associated with self-efficacy to quit (OR: 0.80; 95% CI: 0.68, 0.94 p < .01) and positively associated with being diagnosed with a mental health condition (OR: 1.50; 95% CI: 1.01, 2.25 p < .05). Recent use of NRT was positively associated with mental health condition (OR: 1.39; 95% CI: 1.02, 1.90 p < .05) and negatively associated with alcohol consumption (OR: 0.69; 95% CI: 0.52, 0.92 p < .01). CONCLUSION: Past use of Quitline and pharmacotherapy treatment was associated with self-efficacy to quit, sociodemographic variables, mental health conditions and alcohol consumption. Community-based strategies that target smoking, mental health and drug and alcohol problems may overcome some of the barriers that prevent low-SES populations from engaging with smoking cessation support. PMID- 30290300 TI - Very early drinking: Event history models predicting alcohol use initiation from age 4 to 11 years. AB - While it is not normative to initiate alcohol use prior to adolescence, substantial numbers of children do so. However, relatively little is known about the prevalence or predictors of alcohol initiation in childhood, compared to extensive research on adolescent initiation and alcohol use. The present study examines patterns and predictors of very early drinking initiation in childhood, focusing on child behavioral undercontrol and parent alcohol and drug use as time varying risk factors across childhood, independent of sociodemographic background variables. Event history analyses model and predict the age of alcohol initiation across ages 4 to 11 in the ongoing Millennium Cohort Study. Methodological strengths include the prospective design initiated in infancy (prior to any alcohol consumption), multiple reporters, and large representative sample of children and parents (n = 11,355). Key predictors are child behavioral undercontrol and parent alcohol and drug use assessed across childhood. Weighted results show that <2% of children had their first drink of alcohol prior to their 8th birthday, rising to 13% by age 10-11 years. Odds of initiation are higher when parents rated children as behaviorally undercontrolled and when at least one parent in the household reported drinking alcohol and/or using illegal drugs, independent of sociodemographic group differences. Thus, an important minority initiated drinking during childhood, and there are key risk factors for early drinking. Increased focus on the epidemiology, etiology, and prevention of childhood drinking is needed. PMID- 30290301 TI - Childhood maltreatment and perceived stress in young adults: The role of emotion regulation strategies, self-efficacy, and resilience. AB - Childhood maltreatment has many deleterious outcomes; however, trait resilience as well as emotion regulation strategies, including suppression and reappraisal, may mediate between childhood maltreatment and later perceived stress. For this study, 267 college students (183 females and 84 males; M age = 19.77, SD = 2.29) completed self-report measures of parental psychological and physical maltreatment, parental emotion neglect, habitual use of suppression and reappraisal strategies, emotion regulation self-efficacy, trait resilience, and recent perceived stress. Analyses were conducted to investigate gender-specific associations. In females, both suppression and reappraisal mediated the relationship between maternal/paternal emotional neglect and perceived stress, and suppression also mediated the relationship between maternal psychological maltreatment and perceived stress. Trait resilience mediated the relationships of all three types of maternal maltreatment, paternal psychological maltreatment, and paternal emotional neglect with perceived stress in females. There were no significant mediation effects in males. Thus, interventions aiming at reducing perceived stress associated with maternal or paternal emotional neglect or maternal psychological maltreatment in women may benefit from targeting both suppression and reappraisal. Such interventions may also be enhanced by efforts to strengthen trait resilience. PMID- 30290302 TI - Hydroxycobalamin catalyzes the oxidation of diethyldithiocarbamate and increases its cytotoxicity independently of copper ions. AB - It is known that some metals (Cu, Zn, Cd, Au) markedly increase the toxic effect of thiocarbamates. It was shown in the present study that hydroxycobalamin (a form of vitamin B12, HOCbl), which incorporates cobalt, significantly enhances the cytotoxicity of diethyldithiocarbamate (DDC), decreasing its IC50 value in tumor cells three to five times. The addition of HOCbl to aqueous DDC solutions accelerated the reduction of oxygen. No hydrogen peroxide accumulation was observed in DDC + HOCbl solutions; however, catalase slowed down the oxygen reduction rate. Catalase as well as the antioxidants N-acetylcysteine (NAC) and glutathione (GSH) partially inhibited the cytotoxic effect of DDC + HOCbl, whereas ascorbate, pyruvate, and tiron, a scavenger of superoxide anion, had no cytoprotective effect. The administration of HOCbl into DDC solutions (> 1 mM) resulted in the formation of a crystalline precipitate, which was inhibited in the presence of GSH. The data of UV and NMR spectroscopy and HPLC and Mass Spectrometry (LC/MS) indicated that the main products of the reaction of DDC with HOCbl are disulfiram (DSF) and its oxidized forms, sulfones and sulfoxides. The increase in the cytotoxicity of DDC combined with HOCbl occurred both in the presence of Cu2+ in culture medium and in nominally Cu-free solutions, as well as in growth medium containing the copper chelator bathocuproine disulfonate (BCS). The results indicate that HOCbl accelerates the oxidation of DDC with the formation of DSF and its oxidized forms. Presumably, the main cause of the synergistic increase in the toxic effect of DDC + HOCbl is the formation of sulfones and sulfoxides of DSF. PMID- 30290303 TI - Microstructural brain changes track cognitive decline in mild cognitive impairment. AB - Improved characterization of the microstructural brain changes occurring in the early stages of Alzheimer's disease may permit more timely disease detection. This study examined how longitudinal change in brain microstructure relates to cognitive decline in aging and prodromal Alzheimer's disease. At baseline and two year follow-up, 29 healthy controls and 21 individuals with mild cognitive impairment or mild Alzheimer's disease underwent neuropsychological evaluation and restriction spectrum imaging (RSI). Microstructural change in the hippocampus, entorhinal cortex, and white matter tracts previously shown to be vulnerable to Alzheimer's disease, was compared between healthy controls and impaired participants. Partial correlations and stepwise linear regressions examined whether baseline RSI metrics predicted subsequent cognitive decline, or change in RSI metrics correlated with cognitive change. In medial temporal gray and white matter, restricted isotropic diffusion and crossing fibers were lower, and free water diffusion was higher, in impaired participants. Restricted isotropic diffusion in the hippocampus declined more rapidly for cognitively impaired participants. Baseline hippocampal restricted isotropic diffusion predicted cognitive decline, and change in hippocampal and entorhinal restricted isotropic diffusion correlated with cognitive decline. Within controls, changes in white matter restricted oriented diffusion and crossing fibers correlated with memory decline. In contrast, there were no correlations between rates of cortical atrophy and cognitive decline in the full sample or within controls. Changes in medial temporal lobe microarchitecture were associated with cognitive decline in prodromal Alzheimer's disease, and these changes were distinct from microstructural changes in normal cognitive aging. RSI metrics of brain microstructure may hold value for predicting cognitive decline in aging and for monitoring the course of Alzheimer's disease. PMID- 30290304 TI - miR-7 Suppresses Tumor Progression by Directly Targeting MAP3K9 in Pancreatic Cancer. AB - Extensive research has suggested that miR-7 plays a critical role in cancer progression. However, the biological function of miR-7 in pancreatic cancer (PC) progression is poorly understood. Therefore, in the present study, we investigated the function of miR-7 and its molecular mechanism in PC progression. We used multiple methods, such as MTT, FACS, Transwell assay, RT-PCR, western blotting, and transfection to investigate the role of miR-7 in PC cells. We found that miR-7 suppressed cell growth, migration, and invasion but induced apoptosis in PC cells. Moreover, overexpression of miR-7 repressed tumor growth in mice, suggesting that miR-7 could exert its tumor-suppressive function in PC. Mechanistically, we validated that MAP3K9 is a direct target of miR-7, which significantly enhanced PC cell proliferation and inhibited cell apoptosis partly through activation of the MEK/ERK pathway and NF-kappaB pathway. Moreover, rescue experiments also showed that miR-7 suppressed PC cell proliferation and induced PC cell apoptosis by directly targeting MAP3K9, leading to inhibition of the MEK/ERK and NF-kappaB pathways. Taken together, these results suggest that miR 7/MAP3K9 is critically involved in PC progression and that miR-7 may be a potential target for PC treatment. PMID- 30290305 TI - Ablation of a Single N-Glycosylation Site in Human FSTL 1 Induces Cardiomyocyte Proliferation and Cardiac Regeneration. AB - Adult mammalian hearts have a very limited regeneration capacity, due largely to a lack of cardiomyocyte (CM) proliferation. It was recently reported that epicardial, but not myocardial, follistatin-like 1 (Fstl1) activates CM proliferation and cardiac regeneration after myocardial infarction (MI). Furthermore, bacterially synthesized human FSTL 1 (hFSTL1) was found to induce CM proliferation, whereas hFSTL1 synthesized in mammals did not, suggesting that post-translational modifications (e.g., glycosylation) of the hFSTL1 protein affect its regenerative activity. We used modified mRNA (modRNA) technology to investigate the possible role of specific hFSTL1 N-glycosylation sites in the induction, by hFSTL1, of CM proliferation and cardiac regeneration. We found that the mutation of a single site (N180Q) was sufficient and necessary to increase the proliferation of rat neonatal and mouse adult CMs in vitro and after MI in vivo, respectively. A single administration of the modRNA construct encoding the N180Q mutant significantly increased cardiac function, decreased scar size, and increased capillary density 28 days post-MI. Overall, our data suggest that the delivery of N180Q hFSTL1 modRNA to the myocardium can mimic the beneficial effect of epicardial hFSTL1, triggering marked CM proliferation and cardiac regeneration in a mouse MI model. PMID- 30290306 TI - Protecting Pax6 3' UTR from MicroRNA-7 Partially Restores PAX6 in Islets from an Aniridia Mouse Model. AB - Aniridia is a rare congenital syndrome that is associated with reduced visual acuity and progressive loss of vision. Aniridia patients may also develop systemic health issues associated with defects in the pancreas, digestive, and central nervous systems. The spectrum of symptoms associated with aniridia is due to haploinsufficiency of the paired box 6 gene (PAX6) and its role in the development and maintenance of the affected tissues. Here, we isolated pancreatic islets from mice heterozygous for Pax6 to test whether a Pax6-specific miRNA suppression (target protector) strategy can restore PAX6 protein levels. We show that miR-7 and miR-375 target specific sites within the Pax6 3' UTR in a mouse pancreatic beta-insulinoma cell line. Tough decoys (Tuds) against miR-7 and miR 375 increase expression of a mouse Pax6 3' UTR luciferase reporter and increase PAX6 protein levels in these cells. Finally, we demonstrate that the shielding of the miR-7 binding site with a target protector restores PAX6 protein levels in the Pax6 heterozygous islets. The data presented here represent a proof of concept for RNA-based therapy for the progressive defects associated with aniridia and suggest the target protector approach may be a useful therapeutic strategy for other haploinsufficiency diseases. PMID- 30290308 TI - Effects of OASIS(r) phenolic foam on hydraulic behaviour of permeable pavement systems. AB - Sustainable drainage is a major challenge for highway and environmental agencies to mitigate flooding and understand the optimum design parameters of pavement structure. This paper experiments the hydraulic properties of OASIS(r) phenolic foam material examining infiltration rate and steady-state behaviour, water storage capacity of different thicknesses of OASIS(r) material, and the effect of OASIS(r) material in deferring the water peak flow during rainfall intensities of 100 mm/h, 243 mm/h, 400 mm/h, and 563 mm/h. This paper designs an application programme that estimates the optimal thickness of OASIS(r) layer to retain 100% of stormwater for a duration of 15 min. The results from laboratory tests corroborate the performance efficiency of OASIS(r) material to delay peak stormwater flow and mitigate flooding. The OASIS(r) materials not only increase the ability of permeable pavement system to absorb and retain stormwater up to a saturation limit but also retain the nutrient contaminants infiltrate to groundwater. The designed application programme will help the designers and constructors to increases the drainage efficiency of pavement structure by estimating the optimal thickness of OASIS(r) layer required to delay peak stormwater flow during maximum rainfall intensities. PMID- 30290307 TI - miR-409 Inhibits Human Non-Small-Cell Lung Cancer Progression by Directly Targeting SPIN1. AB - Lung cancers, the leading cause of cancer mortality worldwide, are characterized by a high metastatic potential. Growing evidence reveals that Spindlin 1 (SPIN1) is involved in tumor progression and carcinogenesis. However, the role of SPIN1 in non-small-cell lung cancer (NSCLC) and the molecular mechanisms underlying SPIN1 in human NSCLC remain undetermined. Here we examined the function of SPIN1 in human NSCLC and found that the expression of SPIN1 was closely correlated with the overall survival and poor prognosis of NSCLC patients. Aberrant regulation of microRNAs (miRNAs) has an important role in cancer progression. We revealed that miR-409 inhibits the expression of SPIN1 by binding directly to the 3' UTR of SPIN1 using dual-luciferase reporter assays. Overexpression of miR-409 significantly suppressed cell migration, growth, and proliferation by inhibiting SPIN1 in vitro and in vivo. SPIN1 overexpression in miR-409-transfected NSCLC cells effectively rescued the suppression of cell migration, growth, and proliferation regulated by miR-409. miR-409 regulates the PI3K/AKT (protein kinase B) pathway in NSCLC. Moreover, clinical data showed that NSCLC patients with high levels of miR-409 experienced significantly better survival. miR-409 expression was also negatively associated with SPIN1 expression. Taken together, these findings highlight that the miR-409/SPIN1 axis is a useful pleiotropic regulatory network and could predict the metastatic potential in NSCLC patients early, indicating the possibility that miR-409 and SPIN1 might be attractive prognostic markers for treating NSCLC patients. PMID- 30290309 TI - Comprehensive evaluation and scenario simulation for the water resources carrying capacity in Xi'an city, China. AB - The quantity and quality of water resources are of great importance in maintaining urban socio-economic development. Accordingly, substantial research has been conducted on the concept of the water resources carrying capacity (WRCC). In this study, analytic hierarchy process (AHP) and system dynamics (SD) models were combined to construct a multi-criteria evaluation system of the WRCC and a socio-economic/water resources SD model for Xi'an. The developmental trends of the society, economy, water supply/demand, and wastewater discharge were obtained from 2015 to 2020 using five scenarios designed for distinct purposes; these scenarios and trends were comprehensively evaluated using a combination of qualitative and quantitative analyses. The results indicated that the WRCC (0.32 in 2020) in Xi'an will shift from a normal to a poor state if the current social development pattern is maintained; therefore, we conclude that the socio-economic development of Xi'an is unsustainable. However, under a comprehensive scheme, the WRCC index (0.64 in 2020) will increase by 48% compared with the WRCC index under a business-as-usual scenario. Further, some practical suggestions, including the promotion of industrial reforms and the improvement of water-use efficiency and recycling policies, were provided for improving the regional WRCC. PMID- 30290310 TI - An energy-friendly alternative in the large-scale production of soybean oil. AB - Soybean oil is widely used as cooking oil, whereas the soybean cake is a valuable ingredient for animal food. The extraction of soybean oil is an energy-intensive process, with additional significant impact on the environment via the wastewater and hexane emissions. The research investigated different ways to minimize the energy consumption. In a traditional process, both direct (live) steam and indirect steam heating (jackets, tubular exchangers) are used to deliver the required heat duty. Direct steam injection is restricted to the first evaporator and the stripper, for a total of 620 kg/h. Indirect steam is also applied in the evaporators for a total of 6.44 MW. The desolventizing process requires a steam energy input of 8.15 MW. Integration of a heat exchanger network in the evaporation and stripping part of the process reduces the amount of direct steam usage from 620 kg/h to 270 kg/h and of the indirect heat duty from 6.44 to 5.05 MW. In the cake desolventizing part of the process, the energy requirement is reduced from 8.15 to 2.12 MW. The overall gross energy saving is hence ~50%. The improvements moreover reduce both the waste water loadings by 56.5% and the CO2 emissions by 62.5%. Hexane emissions are moreover significantly (>90%) reduced. PMID- 30290311 TI - The avian influenza virus PA segment mediates strain-specific antagonism of BST 2/tetherin. AB - BST-2 is an antiviral protein described as a powerful cross-species transmission barrier for simian immunodeficiency viruses. Influenza viruses appear to interact with BST-2, raising the possibility that BST-2 may be a barrier for cross-species transmission. An MDCK-based cell line expressing human BST-2 was generated to study human-derived A/Puerto Rico/8/36 (H1N1; PR8) as well as two low pathogenic avian influenza viruses (subtypes H4N6 and H6N1). The H4N6 and H6N1 viruses were less affected by BST-2 expression than PR8, due to their ability to decrease BST 2 levels, a function localized to the PA segment of both avian viruses. Experiments with PA-mutant and -chimeric viruses confirmed that the avian PA segment conferred BST-2 downregulation and antagonism. These results indicate a species-specific ability of PA from low pathogenic avian viruses to mitigate human BST-2 antiviral activity, suggesting that BST-2 is unlikely to be a general cross-species barrier to transmission of such viruses to humans. PMID- 30290313 TI - Netrin-1 prevents the attachment of monocytes to endothelial cells via an anti inflammatory effect. AB - Netrin-1 is best known for its function guiding axon growth and migration. Netrin 1 has been shown to be involved in regulating cardiovascular function. In this study, we aimed to understand the biological role of Netrin-1 and its receptor Unc5b in endothelial cells. Our results demonstrate that Unc5b was moderately expressed in human aortic endothelial cells (HAECs) and TNF-alpha had a dose dependent inhibitory effect on Unc5b level. Netrin-1 potently suppressed TNF alpha-induced vascular adhesion molecules VCAM-1, ICAM-1, E-selectin and blocked the adhesion of monocytes to endothelial cells. Netrin-1 also suppressed TNF alpha-induced production of cytokines including MCP-1, IL-1beta, and IL-6. Importantly, Netrin-1 suppressed toll like receptor 4 (TLR4) expression and prevented NF-kappaB activation. Mechanistically, Netrin-1 reduced TNF-alpha induced IKK and IkappaBalpha activation and prevented degradation of IkappaBalpha. Netrin-1 reduced nuclear accumulation of p65 and strongly suppressed NF-kappaB promoter activation. Collectively, our data demonstrated that signaling of Netrin-1 and its receptor Unc5b had an anti-inflammatory effect in endothelial cells. Netrin-1 signaling could be imperative for normal endothelial function. PMID- 30290314 TI - TGF-beta1-Induced Airway Smooth Muscle Cell Proliferation Involves TRPM7 Dependent Calcium Influx via TGFbetaR/SMAD3. AB - BACKGROUND: TRPM7 in mast cells plays a key role in asthma. However, the effect of TRPM7 on TGF-beta1-induced airway smooth muscle cell (ASMC) proliferation remains unclear. Therefore, we designed this study to explore whether TRPM7 is involved in TGF-beta1-induced ASMC proliferation. METHODS: An asthmatic mouse model was established, and the expressions of TGF-beta1 and TRPM7 in mice lungs were detected using enzyme-linked immunosorbent assay (ELISA) and western blotting. In addition, murine ASMCs were cultured and stimulated with TGF-beta1. Possible TGF-beta1 and TRPM7 interactions were examined using RT-PCR and western blotting analyses with ASMCs. The effect of TRPM7 knockdown on ASMC calcium influx was assessed by the fluorescent indicator indo-1. MTT and flow cytometry were applied to evaluate the effects of TRPM7 knockdown on ASMC proliferation and apoptosis. RESULTS: TGF-beta1 elevated the expression of TRPM7 via TGFbetaR/SMAD3. Knocking down TRPM7 decreased the intracellular Ca2+ concentration and cellular proliferation of ASMCs, although apoptosis remained unaffected. CONCLUSIONS: Our initial findings suggest that TRPM7 inhibition may prevent asthma-induced airway remodeling. PMID- 30290312 TI - Versatile targeting system for lentiviral vectors involving biotinylated targeting molecules. AB - Conjugating certain types of lentiviral vectors with targeting ligands can redirect the vectors to specifically transduce desired cell types. However, extensive genetic and/or biochemical manipulations are required for conjugation, which hinders applications for targeting lentiviral vectors for broader research fields. We developed envelope proteins fused with biotin-binding molecules to conjugate the pseudotyped vectors with biotinylated targeting molecules by simply mixing them. The envelope proteins fused with the monomeric, but not tetrameric, biotin-binding molecules can pseudotype lentiviral vectors and be conjugated with biotinylated targeting ligands. The conjugation is stable enough to redirect lentiviral transduction in the presence of serum, indicating their potential in in vivo . When a signaling molecule is conjugated with the vector, the conjugation facilitates transduction and signaling in a receptor-specific manner. This simple method of ligand conjugation and ease of obtaining various types of biotinylated ligands will make targeted lentiviral transduction easily applicable to broad fields of research. PMID- 30290315 TI - Developing agent-based models of complex health behaviour. AB - Managing non-communicable diseases requires policy makers to adopt a whole systems perspective that adequately represents the complex causal architecture of human behaviour. Agent-based modelling is a computational method to understand the behaviour of complex systems by simulating the actions of entities within the system, including the way these individuals influence and are influenced by their physical and social environment. The potential benefits of this method have led to several calls for greater use in public health research. We discuss three challenges facing potential modellers: model specification, obtaining required data, and developing good practices. We also present steps to assist researchers to meet these challenges and implement their agent-based model. PMID- 30290316 TI - A senior high school-based survey on the long-term impact of the Wenchuan earthquake on survivors' quality of life: PTSD as a mediator. AB - Previous earthquake-related studies mostly focused on the prevalence and risk factors of post-traumatic stress disorder (PTSD), and there are only a few articles on the subsequent long-term outcomes of earthquakes. This study aimed to investigate the long-term impact of the Wenchuan earthquake on the quality of life (QOL) of surviving senior high school students 2-3 years post-disaster and to clarify whether PTSD was a mediator in the relationship of earthquake-related exposure and QOL. The study collected 1031 survivors' self-report questionnaires on socio-demographic data, earthquake-related experiences, PTSD symptoms (PCL-C), and QOL (WHOQOL-BREF). The results showed that earthquake-related exposure experiences were negatively associated with QOL scores, and the severity of PTSD symptoms was significantly and negatively related to QOL scores. Structural equation model (SEM) analysis showed that earthquake-related exposure was directly related to the severity of PTSD symptoms, while insignificantly directly related to QOL. Therefore, earthquake-related exposure was indirectly related to QOL (totally mediated by severity of PTSD symptoms). PTSD was a mediator in the relationship between earthquake-related exposure and QOL among adolescents: earthquake-related exposure affected the survivors' QOL mainly mediated by the PTSD symptoms that developed. Therefore, to improve the QOL of the survivors after an earthquake, more attention should be paid to survivors who have PTSD symptoms. PMID- 30290317 TI - Obsessive-compulsive symptom dimensions: Association with comorbidity profiles and cognitive-behavioral therapy outcome in pediatric obsessive-compulsive disorder. AB - Our aims were to examine: (1) classes of comorbid disorders in a sample of children and adolescents with Obsessive-Compulsive Disorder (OCD), (2) how these classes relate to obsessive-compulsive symptom dimensions, and (3) the extent to which obsessive-compulsive symptom dimensions predict Cognitive-Behavioral Therapy (CBT) outcome. Participants (N = 269) were assessed with the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS-PL) and the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS). Latent Class Analysis (LCA) was used to identify comorbidity classes. Regression analyses were used to evaluate symptom dimensions as predictors of treatment outcome and their relation to comorbidity classes. Comorbidity was included in the treatment outcome analyses as it can affect outcome. Comorbidity was best categorized by a three-class model and each class was distinctively correlated with the OCD symptom dimensions. Higher scores on the symmetry/hoarding factor increased the chance of responding to CBT by an odds ratio of 1.56 (p = 0.020) when controlled for age, gender, and comorbidity class. The harm/sexual factor (p = 0.675) and contamination/cleaning factor (p = 0.122) did not predict CBT outcome. Three clinically relevant comorbidity subgroups in pediatric OCD were identified. Patients who exhibited higher levels of symmetry/hoarding dimension were more prone to respond to CBT. PMID- 30290318 TI - Effects of perceived stress and professional values on clinical performance in practice nursing students: A structural equation modeling approach. AB - BACKGROUND: Clinical performance is regarded as a basic and core content of nursing quality. Professional values of nursing students may play an important role in improving clinical performance. Few studies reveal the relationship between professional values, perceived stress and clinical performance. This research has found that professional values play a moderating role in the relationship between perceived stress and clinical performance. OBJECTIVE: To examine the negative association between perceived stress and clinical performance among practice nursing students, and to determine whether professional values plays a moderating role in the relationship between perceived stress and clinical performance among Chinese practice nursing students. DESIGN: A cross-sectional descriptive design has been used. METHODS: From May to June 2017, a total of 435 Chinese practice nursing students from 4 hospitals filled out the questionnaires. The response rate was 94.57%. Three questionnaires including the Perceived Stress Scale (PSS), Nursing Professional Value Scale Revised (NPVS-R), and Clinical Performance Scale (CPS). Structural equation modeling was used to deal with the relationships among perceived stress, professional values, and clinical performance. RESULTS: Perceived stress was negatively associated with clinical performance (P < 0.01). Professional values significantly affected clinical performance (P < 0.01) and moderated the relationship between perceived stress and clinical performance (P < 0.01). CONCLUSIONS: Perceived stress is negatively related to clinical performance among Chinese practice nursing students, and professional values moderates the relationship between perceived stress and clinical performance, which can form scientific evidence to develop intervention strategies to improve clinical performance. PMID- 30290319 TI - The concept of caring amongst first year diagnostic radiography students: Original research. AB - Student radiographers start their work integrated learning from their first year of studying and they are in constant contact with patients. Based on this interaction, it is imperative for all diagnostic radiography students to be caring professionals. The purpose of this study was to gain an understanding of caring amongst diagnostic student radiographers by exploring and describing their experiences of caring in the clinical environment. A qualitative, exploratory, descriptive and contextual research design was utilized. Focus group interviews were conducted with first year diagnostic radiography students. Purposive sampling was used to ensure information rich data was obtained. In keeping with qualitative research, participants were interviewed until data saturation was reached. Appreciative inquiry was used as an interview technique to encourage storytelling and to engage in narrative - rich communication. The 4-D model of appreciative inquiry, namely; Discovery, Dream, Destiny and Design, formed the basis for the interview questions. Data was analysed and coded and themes were created based on the interpretation of the data. Three themes were identified as being; caring as an integral part of a career choice, unpreparedness for interpersonal interactions and barriers and enablers for the development of a caring identity. Participants expressed an idealistic vision of what caring means to them as a student radiographer. Participants felt unprepared for their daily interpersonal interactions with patients and other staff. Recommendations to radiography educators would be to engage in more role-playing exercises, reflective practices and peer discussions. PMID- 30290320 TI - Health anxiety and cyberchondria among Ege University health science students. AB - It is common among health science students to incorrectly believe that they have contracted certain diseases they have recently studied. This can also be seen in the form of health anxiety and investigating health-related information via the internet. Health anxiety, cyberchondria and affecting factors are determined among health science students. The study was conducted at the faculties of Medicine, Pharmacy, Dentistry and Nursing in 2016-2017 with the participation of 874 students. The data were gathered using a questionnaire as well as health anxiety and cyberchondria severity scales. In the presence of a health problem, 14.2% of students seek health information via the internet. 83.7% use mobile phone to access the internet, 1/4 of students conduct health scanning once a week or more. To 65.4%, internet information is correct at medium and above level. No statistically significant difference was found with respect to students' gender, high school, places they lived before, parents' education and scales' scores. The cyberchondria scores of students with health problems are higher in the whole scale and in "distress and mistrust of medical professional" subscales. As the frequency of scanning on the internet increases, the scores of cyberchondria also increase significantly. Medical students had significantly higher scores in "distress, excessiveness and reassurance" subscales. Male students' "mistrust of medical professional and compulsion" subscales scores were also higher. It was determined that the presence of the health problem was effective on the cyberchondria. Identification of somatoform problems like health anxiety and cyberchondria may help to regulate the education program. PMID- 30290321 TI - Nitritation, nitrous oxide emission pathways and in situ microbial community in a modified University of Cape Town process. AB - Achieving nitritation is a prerequisite to promote nutrients removal and save energy, but emission of nitrous oxide as a greenhouse gas cannot be ignored. This study established the nitritation in a continuous-flow MUCT process and investigated the mechanism of N2O generation. The nitrite accumulation ratio (NAR) reached 95% by controlling the low DO of 0.3-0.5 mg/L and short HRT of 8 h. The 15N-isotope tracer experiment indicated that the percentage of nitrifier denitrification (ND) pathway increased by 12.7% under the limited-aeration mode, improving the stable operating of nitritation. Meanwhile, the autotrophic anammox pathway increased with the contribution ratio of 14.7% to N2 emission under the nitritation mode. The 15N-DNA-SIP revealed that the Nitrosomonas executed the ND pathway and the Planctomycetes conducted the anammox process, respectively. The integration of autotrophic and heterotrophic process based on nitritation technique has potential to solve the carbon-limited issue for total nitrogen removal in mainstream WWTPs. PMID- 30290322 TI - Denitrification- and anammox-dominant simultaneous nitrification, anammox and denitrification (SNAD) process in subsurface flow constructed wetlands. AB - Simultaneous nitrification, anammox and denitrification (SNAD) process was developed in subsurface flow constructed wetlands (SFCWs) to treat polluted surface water. The effects of vegetation, hydraulic retention time (HRT), C/N, and influent nitrogen forms on nitrogen removal and microbial communities were investigated. Results showed that denitrification- and anammox-dominant SNAD corresponded to nitrate- and ammonia-dominant influent, respectively, and both could achieve more efficient nitrogen removal in planted SFCWs than the unplated. These higher efficiencies were due to the microbial growth, organic carbon release, oxygen supply and plant uptake promoted by vegetation. The electron donors accelerated denitrification but inhibited ammonia oxidation with deficient oxygen. Anammox contributed to nitrogen removal of 27.34% under oxygen-limited conditions without vegetation. Anammox combined with denitrification and plant uptake were over 90% in planted SFCWs. For the investigated factors, the ammonia, nitrate and C/N were the most significant ones influencing the microbial communities, further nitrogen removal pathways and performances. PMID- 30290323 TI - Bioconversion of plant biomass hydrolysate into bioplastic (polyhydroxyalkanoates) using Ralstonia eutropha 5119. AB - Pretreatment of lignocellulosic biomass results in the formation of byproducts (furfural, hydroxymethylfurfural [HMF], vanillin, acetate etc.), which affect microbial growth and productivity. Furfural (0.02%), HMF (0.04%), and acetate (0.6%) showed positive effects on Ralstonia eutropha 5119 growth and polyhydroxyalkanoate (PHA) production, while vanillin exhibited negative effects. Response optimization and interaction studies between the variables glucose, ammonium chloride, furfural, HMF, and acetate using the response surface methodology resulted in maximum PHA production (2.1 g/L) at optimal variable values of 15.3 g/L, 0.43 g/L, 0.04 g/L, 0.05 g/L, and 2.34 g/L, respectively. Different lignocellulosic biomass hydrolysates (LBHs), including barley biomass hydrolysate (BBH), Miscanthus biomass hydrolysate (MBH), and pine biomass hydrolysate (PBH), were evaluated as potential carbon sources for R. eutropha 5119 and resulted in 1.8, 2.0, and 1.7 g/L PHA production, respectively. MBH proved the best carbon source, resulted in higher biomass (Yx/s, 0.31 g/g) and PHA (Yp/s, 0.14 g/g) yield.

PMID- 30290325 TI - New-onset interictal headache in Persons with epilepsy (PWE): A case-control study. AB - PURPOSE: In our personal experience, headache is a frequent complaint in Persons with epilepsy (PWE) receiving antiepileptic drugs (AEDs), carbamazepine (CBZ) in particular. There is hardly any systematic study on AEDs-associated headache. We assessed the association of new-onset interictal headache in PWE with CBZ compared with other AEDs and factors associated with it. METHODS: Two thousand PWE on AEDs were screened, and 165 persons having new-onset interictal headache were identified. Eight persons were excluded because of comorbid illnesses that could potentially contribute to a headache. Finally, 157 were recruited for the study. One hundred fifty-seven age- and sex-matched PWE on AEDs, without headache, were recruited as controls. Headache questionnaire based on the International Classification of Headache Disorders (ICHD-II) criteria was used. Demographic factors, seizure characteristics, type and dose of AEDs, findings on electroencephalogram (EEG), and magnetic resonance imaging (MRI)/computerized tomography (CT) were recorded. RESULTS: Among PWE with headache, the majority [88 (56.1%)] were on CBZ compared with other AEDs but not significantly different from controls. In 71 (45%) persons, the headache had migrainous character. In both univariate and multivariate analyses, lower seizure frequency and fewer EEG abnormalities were found to be independent predictors of headache. CONCLUSIONS: New-onset interictal headache is a significant issue in PWE; nonmigrainous headache is more common than the migrainous type. Carbamazepine was not found to have any predilection for new-onset interictal headache compared with other AEDs. A lower frequency of seizures and EEG abnormalities in PWE with headache may suggest that seizures contribute less to the development of headache and may further support the hypothesis that AEDs may be significant contributing factors for the headache. PMID- 30290326 TI - Multivariable prediction model of drug resistance in adult patients with generalized epilepsy from Colombia: A case-control study. AB - INTRODUCTION: Patients with drug-resistant epilepsy (DRE) account for most of the burden of epilepsy, and they have poor prognosis in seizure control, higher morbidity, and mortality. OBJECTIVES: The objective of the study was to develop a prognostic model of drug resistance in adult patients with generalized epilepsy from Colombia. METHODS: In this case-control study of patients with generalized epilepsy, patients were separated into two groups: one group with DRE (cases) according to the new International League Against Epilepsy (ILAE) definition after a complete evaluation performed by an epileptologist and the other group without DRE (control). Variables were analyzed to identify statistical differences between groups and were then selected to construct a prognostic model from a logistic regression. RESULTS: One hundred thirty-three patients with generalized epilepsy were studied. Thirty-eight (28.5%) patients had DRE, and 95 (71.5%) did not have DRE. History of status epilepticus, abnormal findings from neurological examination, aura, any degree of cognitive impairment, epileptic seizures at any moment of the day, and any comorbidity were risk factors. The presence of seizures only in the waking state and idiopathic etiology were protective factors. A prognostic model was constructed with previously reported risk factors for DRE and other variables available in the population of this study. In the multivariable analysis, the history of status epilepticus (odds ratio (OR): 5.6, confidence interval (CI): 1.1-20.0, p = 0.031), abnormal findings from neurological examination (OR: 5.7, CI: 2.3-13.9, p = 0.000), and aura (OR: 6.1, CI: 1.8-20.8, p = 0.003) were strongly associated with DRE. CONCLUSIONS: In adult patients with generalized epilepsy, aura, abnormal findings from neurological examination, and history of status epilepticus were predictive factors for DRE. PMID- 30290327 TI - Plant-lead interactions: Transport, toxicity, tolerance, and detoxification mechanisms. AB - Natural and human activities introduced an excess level of toxic lead (Pb) to the environment. Pb has no known biological significance and its interactions with plants lead to the production of reactive oxygen species (ROS). Pb and/or ROS have the potential to cause phytotoxicity by damaging the tissue ultrastructure, cellular components, and biomolecules. These damaging effects may possibly result in the inhibition of normal cellular functioning, physiological reactions, and overall plant performances. ROS play a dual role and act as a signaling molecule in plant defense system. This system encircles enzymatic and non-enzymatic antioxidative mechanisms. Catalase, superoxide dismutase, peroxidase, and enzymes from the ascorbate-glutathione cycle are the major enzymatic antioxidants, while non-enzymatic antioxidants include phenols, flavonoids, ascorbic acid, and glutathione. Pb removal from contaminated sites using plants depend on the plant's Pb accumulation capacity, Pb-induced phytotoxicity, and tolerance and detoxification mechanisms plants adopted to combat against this phytotoxicity. However, the consolidated information discussing Pb-plant interaction including Pb uptake and its translocation within tissues, Pb-mediated phytotoxic symptoms, antioxidative mechanisms, cellular, and protein metabolisms are rather limited. Thus, we aimed to present a consolidated information and critical discussions focusing on the recent studies related to the Pb-induced toxicity and oxidative stress situations in different plants. The important functions of different antioxidants in plants during Pb stress have been reviewed. Additionally, tolerance responses and detoxification mechanisms in the plant through the regulation of gene expression, and glutathione and protein metabolisms to compete against Pb-induced phytotoxicity are also briefly discussed herein. PMID- 30290328 TI - The role of minocycline in alleviating aluminum phosphide-induced cardiac hemodynamic and renal toxicity. AB - Poisoning with aluminum phosphide (AlP) has been attributed to the high rate of mortality among many Asian countries. It affects several organs, mainly heart and kidney. Numerous literature demonstrated the valuable effect of minocycline in mitigating pathological symptoms of heart and kidney disease. The aim of the present study was to evaluate the probable protective effect of minocycline on cardiac hemodynamic parameters abnormalities and renal toxicity induced by AlP poisoning in the rat model. AlP was administered by gavage at 12 mg/kg body weight followed by injection of minocycline for two interval times of 12 and 24 h, at 40, 80, 120 mg/kg body weight. Electrocardiographic (ECG) parameters were monitored, 30 min after AlP gavage for 6 h using an electronic cardiovascular monitoring device. Kidney tissue and serum were collected for the study of histology, mitochondrial complexes I, II, IV, lactate dehydrogenase (LDH) and myeloperoxidase (MPO) activity, ADP/ATP ratio, mitochondrial cytochrome c release, apoptosis, lactate, BUN, and Cr levels. The results demonstrated that AlP induces ECG abnormalities, and failure of heart rate and blood pressure, which improved significantly by minocycline. Minocycline treatment significantly improved complexes I, IV, MPO and LDH activities, and also reduced the ADP/ATP ratio, lactate level, release of cytochrome c, and apoptosis in the kidney following AlP-poisoning. Also, the histological results showed an improvement of kidney injury in minocycline treated groups. In conclusion, the findings of this study showed that minocycline could improve cardiac hemodynamic abnormalities and kidney injury following AlP-poisoning, suggesting minocycline might be a possible candidate for the treatment of AlP-poisoning.

AB - Atomic Force Microscopy (AFM) plays a vital role in nanoscience and nanotechnology due to its nanoscale resolution. However, the realization of highly precise measurement for AFM is still a challenge. A main factor is the positioning accuracy of the piezoelectric scanner (PZT), affected significantly by the hysteresis of PZT. The paper reports a new dynamic polynomial fitting method modeling hysteresis to achieve the inverse model of the PZT. The inverse model is used as the feedforward input, combined with the fuzzy feedback controller proposed in our former paper, to correct the nonlinear errors induced by the hysteresis. The method is demonstrated to be effective in improving the positioning accuracy of the lateral PZT. Its accuracy can achieve 1 nm. PMID- 30290330 TI - Influence of phosphate on tungstate sorption on hematite: A macroscopic and spectroscopic evaluation of the mechanism. AB - The environmental fate of the tungstate (VI) oxyanion [ e.g. mono tungstate and several polytungstate, generally expressed by W (VI)] is largely controlled by sorption on soil minerals, especially on iron oxide minerals. Molecular scale evaluation of W (VI) retention on iron oxides in the presence of competing oxyanions is scarce in literature. Here we report surface interaction mechanisms of W (VI) on hematite in the presence of phosphate (P) using macroscopic and in situ attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopic experiments. Batch sorption experiments were conducted using 2 g L 1 hematite and 100 MUM W (VI) and P, in single ion system and in binary mixtures as a function of pH (4-11). In situ ATR-FTIR spectroscopic evaluation of P and W (VI) sorption on hematite was also carried out. The results from macroscopic experiments indicated that W (VI) sorption on hematite was not affected by P when W (VI) was added first. The influence of P on W (VI) sorption was noticed when W (VI) & P were added simultaneously or P was added first. The in situ ATR-FTIR spectroscopic data corroborated these findings. In addition, the spectroscopic data revealed that in the presence of P, the surface complexation mode of W (VI) differed as noted from either the absence of WO antisymmetric infrared (IR) band or the WOW stretching band. This study provides useful information on molecular level understanding of W (VI) surface complexation on hematite in the presence of competing ions such as P.

AB - Involvement of flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN) in cellular homeostasis has been well established for tissues other than the retina. Here, we present an optimized method to effectively extract and quantify FAD and FMN from a single neural retina and its corresponding retinal pigment epithelium (RPE). Optimizations led to detection efficiency of 0.1 pmol for FAD and FMN while 0.01 pmol for riboflavin. Interestingly, levels of FAD and FMN in the RPE were found to be 1.7- and 12.5-fold higher than their levels in the retina, respectively. Both FAD and FMN levels in the RPE and retina gradually decline with age and preceded the age-dependent drop in the functional competence of the retina as measured by electroretinography. Further, quantifications of retinal levels of FAD and FMN in different mouse models of retinal degeneration revealed differential metabolic requirements of these two factors in relation to the rate and degree of photoreceptor degeneration. We also found twofold reductions in retinal levels of FAD and FMN in two mouse models of diabetic retinopathy. Altogether, our results suggest that retinal levels of FAD and FMN can be used as potential markers to determine state of health of the retina in general and more specifically the photoreceptors. PMID- 30290332 TI - Dietary fatty acids augment tissue levels of n-acylethanolamines in n acylphosphatidylethanolamine phospholipase D (NAPE-PLD) knockout mice. AB - N-acylethanolamines (NAEs) are lipid signaling mediators, which can be synthesized from dietary fatty acids via n-acylphosphatidylethanolamine phospholipase D (NAPE-PLD) and in turn influence physiological outcomes; however, the roles of NAPE-PLD upon dietary fatty acid modulation are not fully understood. Presently, we examine if NAPE-PLD is necessary to increase NAEs in response to dietary fatty acid manipulation. Post-weaning male wild-type (C57Bl/6), NAPE-PLD (-/+) and NAPE-PLD (-/-) mice received isocaloric fat diets containing either beef tallow, corn oil, canola oil or fish oil (10% wt/wt from fat) for 9 weeks. Brain docosahexaenoic acid (DHA) levels were higher (P<.01) in NAPE-PLD (-/+) (10.01+/-0.31 MUmol/g) and NAPE-PLD (-/-) (10.89+/-0.61 MUmol/g) than wild-type (7.72+/-0.61 MUmol/g) consuming fish oil. In NAPE-PLD (-/-) mice, brain docosahexaenoylethanolamide (DHEA) levels were higher (P<.01) after fish oil feeding suggesting that NAPE-PLD was not necessary for DHEA synthesis. Liver and jejunum arachidonoylethanolamide, 1,2-arachidonoylglycerol and DHEA levels reflected their corresponding fatty acid precursors suggesting that alternate pathways are involved in NAE synthesis. NAPE-PLD (-/-) mice had lower oleoylethanolamide levels in the jejunum and a leaner phenotype compared to wild type mice. Overall, these results demonstrate that dietary fatty acid can augment tissue NAEs in the absence of NAPE-PLD. PMID- 30290333 TI - Possible interaction of ROS, antioxidants and ABA to survive osmotic stress upon acclimation in Vigna radiata L. Wilczek seedlings. AB - Acclimation is a process of adjustment to gradual environmental change that enables plants to survive further stress by triggering some tolerance mechanism possibly involving ABA, ROS and oxidative metabolism. Here we have studied acclimation responses in terms of the performances with regard to physiological (growth and relative water content) and biochemical (chlorophyll, carotenoids, protein, malondialdehyde, sugar content) attributes, ABA production and stomatal sensitivity to exogenous ABA, extracellular ROS production and activation of antioxidant system. Our study reveals that repeated exposure to short-term mild water stress simulated by polyethylene glycol (PEG-6000) induces acclimation in mung bean (Vigna radiata L. Wilczek) seedlings. Acclimation induced tolerance was associated with reduced leaf size and enhanced root growth, accumulation of soluble sugar as osmoprotectant, maintenance of water potential, lessening of membrane damage as indicated by lower MDA content. Acclimated mung bean seedlings have shown greater degree of tolerance through increased production of and enhanced sensitivity to ABA (as reflected by faster stomatal closure), enhanced production of extracellular O2.- and H2O2 and the elevated activities of antioxidative enzymes to control the oxidative burst. Taken together, the results convey that acclimated seedlings minimize osmotic stress-induced damage through a possible network of ABA, ROS and antioxidants. PMID- 30290334 TI - Soybean leaves transcriptomic data dissects the phenylpropanoid pathway genes as a defence response against Phakopsora pachyrhizi. AB - Asian soybean rust (ASR), caused by the obligate biotrophic fungus Phakopsora pachyrhizi, is responsible for severe yield losses of up to 90% in all soybean producing countries. Till today, eight resistance to Phakopsora pachyrhizi (Rpp) loci have been mapped in soybean. Their resistance mechanism is race specific but largely unknown. The transcriptomes of susceptible BRS184 and Rpp3 with ASR isolates T1-2 at 24 h after inoculation (hai) and without ASR inoculation (mock) were annotated by similarity searching with different databases. A total of 4518 differentially expressed genes were identified. We found 70.89%, 56.61%, 32.13%, and 56.04% genes in the protein family databases (PFAM), Gene Ontology (GO), Eukaryotic clusters of Orthologous Groups (KOG), and Kyoto Encyclopedia of Genes and Genomes Pathway (KEGG), respectively. KEGG disclosed that 52% of the phenylpropanoid pathway related genes were up-regulated. The relative gene expression study for selected genes of that pathway was conducted by RT-qPCR using Rpp1-Rpp4 carrying lines with T1-2 infection. The RT-qPCR results revealed that the Rpp lines utilized these genes in a rate limiting manner as a defence response. With the exception of glycinol 4-dimethylallyltransferase (G4DT) and chalcone reductase (CHR), all the genes showed the greatest expression at 12 hai, but the gene expressions which occur between 24 and 96 hai make these Rpp lines unique to their respective ASR isolates. Moreover, functional coordination of arogenate dehydratase 6 (ADT6) and 4-hydroxy-3-methylbut-2-enyl diphosphate synthase (ispG), chalcone synthase (CHS) and CHR, and G4DT and phytyltransferase 3 (PT3) may have a great impact on soybean resistance against ASR. PMID- 30290335 TI - Effects of non-uniform root zone salinity on growth, ion regulation, and antioxidant defense system in two alfalfa cultivars. AB - A split-root system was established to investigate the effects of uniform (0/0, 50/50, and 200/200 mM salt [NaCl]) and non-uniform (0/200 and 50/200 mM NaCl) salt stress on growth, ion regulation, and the antioxidant defense system of alfalfa (Medicago sativa) by comparing a salt-tolerant (Zhongmu No.1) and salt sensitive (Algonquin) cultivar. We found that non-uniform salinity was associated with greater plant growth rate and shoot dry weight, lower leaf Na+ concentration, higher leaf potassium cation (K+) concentration, lower lipid peroxidation, and greater superoxide dismutase (EC 1.15.1.1), catalase (EC 1.11.1.6), and peroxidase (EC 1.11.1.7) activities, compared to uniform salt stress in both alfalfa cultivars. Under non-uniform salinity, a significant increase in Na+ concentration and Na+ efflux and a decline in K+ efflux in the no saline or low-saline part of the roots alleviated salt damage. Our results also demonstrated that proline and antioxidant enzymes accumulated in both the no- or low-saline and high-saline roots, revealing that osmotic adjustment and antioxidant defense had systemic rather than localized effects in alfalfa plants, and there was a functional equilibrium within the root system under non-uniform salt stress. The salt-tolerant cultivar Zhongmu No.1 exhibited greater levels of growth compared to Algonquin under both uniform and non-uniform salt stress, with Na+ tolerance and efflux abilities more effective and greater antioxidant defense capacity evident for cultivar Zhongmu No.1. PMID- 30290336 TI - Climate change in Malaysia: Trends, contributors, impacts, mitigation and adaptations. AB - PURPOSE: This paper reviews the past and future trends of climate change in Malaysia, the major contributors of greenhouse gases and the impacts of climate change to Malaysia. It also reviews the mitigation and adaptations undertaken, and future strategies to manage the impacts of regional climate change. METHODOLOGY: The review encompasses historical climate data comprising mean daily temperature, precipitation, mean sea level and occurrences of extreme weather events. Future climate projections have also been reviewed in addition to scholarly papers and news articles related to impacts, contributors, mitigation and adaptations in relation to climate change. FINDINGS: The review shows that annual mean temperature, occurrences of extreme weather events and mean sea level are rising while rainfall shows variability. Future projections point to continuous rise of temperature and mean sea level till the end of the 21st century, highly variable rainfall and increased frequency of extreme weather events. Climate change impacts particularly on agriculture, forestry, biodiversity, water resources, coastal and marine resources, public health and energy. The energy and waste management sectors are the major contributors to climate change. Mitigation of and adaptations to climate change in Malaysia revolve around policy setting, enactment of laws, formulation and implementation of plans and programmes, as well as global and regional collaborations, particularly for energy, water resources, agriculture and biodiversity. There are apparent shortcomings in continuous improvement and monitoring of the programmes as well as enforcement of the relevant laws. ORIGINALITY/VALUE: This paper presents a comprehensive review of the major themes of climate change in Malaysia and recommends pertinent ways forward to fill the gaps of mitigation and adaptations already implemented. PMID- 30290337 TI - Size-dependent concentrations and bioaccessibility of organophosphate esters (OPEs) in indoor dust: A comparative study from a megacity and an e-waste recycling site. AB - Indoor dust ingestion is an important pathway in human exposure to environmental pollutants, and the bioaccessibility of pollutants can largely influence human exposure risk assessment. In the present study, the concentrations and compositions of organophosphate esters (OPEs) were investigated for different sizes (50 MUm to 2 mm) of indoor dust collected from a megacity, Guangzhou, and an e-waste recycling site. The concentrations of total OPEs were 5360 to 6830 ng/g and 560 to 20,500 ng/g across all sizes of dust from Guangzhou and the e waste site, respectively. The levels and compositions of OPEs were consistent in different fractions of dust from Guangzhou. The highest concentrations of OPEs were found in the finest fraction of dust from the e-waste site. OPEs in Guangzhou dust showed decreasing bioaccessibility when the log KOW of FRs increased from 4 to 11. The bioaccessibility of most OPEs in dust from the e waste site was much lower than those in Guangzhou dust, indicating low bioaccessibility in the components of dust, such as e-waste debris, from the e waste site. The human exposure risks of OPEs in dust from Guangzhou were generally higher than those in dust from the e-waste site. Chitosan and montmorillonite could significantly decrease the bioaccessibility of all OPEs, except for tri-ethyl phosphate (TEP) and tris-(2-butoxyethyl) phosphate (TBOEP) in dust (p < 0.05), indicating chitosan and montmorillonite as promising food additives to enhance the elimination of OPEs. PMID- 30290339 TI - Impact of sediment dredging on sediment phosphorus flux in a restored riparian wetland. AB - Many riverine wetlands have been drained for the creation of agricultural land; however, global declines in freshwater biodiversity have begun to motivate wetland restoration projects around the world. Legacy phosphorus (P) increases the risk that wetland restoration may liberate excess P to the water column and connecting waterbodies, resulting in a trade-off of restored habitat for degraded water quality. To avoid this trade-off, we dredged a former agricultural parcel prior to hydrologic reconnection, and evaluated restoration success by comparing sediment P dynamics before and after dredging. First, results from P adsorption isotherm experiments suggested that after dredging, the sediment would act as a sink for dissolved P only when water column soluble reactive phosphorus (SRP) concentrations exceeded 40 MUg L-1. Additionally, the dredging depth (~1 m on average) exposed sediment with significantly reduced P sorption capacities. Second, P release rates were measured in sediment cores that were incubated under two water temperatures (ambient; +2 degrees C) and two oxygen levels (oxic; hypoxic). Average maximum total phosphorus (TP) release rates ranged from 40 to 85 mg m-2 d-1 before dredging and from 0 to 7 mg m-2 d-1 after dredging, resulting in a 95-99% reduction in TP release rates after dredging. Similar reductions were measured also for SRP release rates. The significant reduction in sediment P release after dredging now creates a high potential for this restored wetland to reduce net P loads into downstream waters by facilitating the deposition and burial of particulate P. We conclude that sediment dredging can be a useful technique for balancing the goals of habitat restoration and water quality improvements in wetlands restored on former agricultural lands. PMID- 30290338 TI - Improvement of the electro-bioremediation process of a non-polar herbicide polluted soil by means of surfactant addition. AB - Oxyfluorfen is a non-polar herbicide that may cause severe soil pollution. The present work studies the possible improvement due to surfactant addition in the efficiency of electro-bioremediation of a clay soil polluted which such a non polar, low-mobility pollutant. Two-week-long batch electro-bioremediation experiments were performed in a bench-scale device. Oxyfluorfen-polluted soil (20 mg kg-1) was inoculated with an acclimated microbial culture, and several experiments were performed using different surfactant concentrations in the electrode wells (0.0, 2.5, 5.0, 10.0 and 20.0 g L-1 of SDS, sodium dodecyl sulphate). Experiments were performed under 1.0 V cm-1 and electrode polarity reversal. It was observed that the electro-osmotic flow (EOF) increased with SDS concentration and that SDS was successfully distributed across the soil, probably improving the oxyfluorfen mobility. Additionally, microbiological activity was fully maintained during the experiments. Electro-bioremediation without SDS removed 14% of the oxyfluorfen, while under 2.5 g L-1 SDS, the efficiency increased to 22% because of an expected improvement in the contact between the different species in the soil. However, higher SDS concentrations (between 10.0 and 20.0 g L-1) caused a decrease in the oxyfluorfen removal efficiency, as SDS is an easily biodegradable compound and was preferably used as substrate by the microbial culture instead of oxyfluorfen. Additionally, the use of high concentrations of SDS was clearly inefficient, as high amounts of the surfactant were lost through the EOF, and even low amounts of oxyfluorfen were removed to the electrode wells, which means that ex situ treatment of the polluted water would be needed.

AB - Zinc and aluminum layered double hydroxides (Zn-Al LDH) are a common group of major Zn species in various Zn-contaminated soil/sediment environments, yet their formation pathways and underlying mechanisms under varied conditions are not well understood. This study investigated the formation of Zn-Al LDHs through the direct interaction of two solid substrates, ZnO nanoparticles (NPs) and a representative Al oxide, gamma-Al2O3. Batch experiments and complementary microscopic and spectroscopic analyses were conducted to elucidate the reaction kinetics and mechanisms, as well as the morphologic and structural evolution of the products. Dissolved Zn and Al concentrations decreased significantly in a dual solid system compared to a single solid system. A bulk Zn-Al LDH phase was found to form under a wide pH range (6.5-9.5). Aside from Zn-Al LDH, gamma-Al2O3 was the main remaining solid phase at pH 6.5, whereas ZnO NPs were the main residual solid phases at pH 9.5. Formation of amorphous Zn(OH)2 was also observed at both pH values, likely due to Zn2+ release at low pH and Al(OH)4- adsorption at high pH. It is proposed that the formation of Zn-Al LDH occurs via a dissolution-sorption-coprecipitation process, where the solubility of ZnO NPs or gamma-Al2O3 solid phases determines the reaction pathways and kinetics under varied pH conditions. The results from this work revealed the transformation mechanisms for ZnO NPs under conditions from weakly acidic to alkaline pH with highly available Al particles and shed light on the environmental fate of ZnO NPs in Zn or ZnO NP contaminated environments.

AB - Although biochar amendment to soil has achieved widely recognized benefits such as plant growth improvement and carbon sequestration, what impact it would have on soil carbon cycling, especially on the behavior of the active dissolved organic matter (DOM), is still unclear. This study evaluated biochar's effects on soil properties and the characteristics of DOM exporting from a cropland Entisol. The soil is the major arable land resource in the upper reaches of the Yangtze River, China and noted for its low soil organic matter and prevalence of preferential flow. Surface runoff, soil pore water and leachate were collected from the field upon a series of natural rainfall. Concentration of dissolved organic carbon (DOC) of soil pore water was found to respond strongly toward the rainfalls. Biochar application led to relatively higher DOC levels within the soil (p > 0.05). Despite apparent increase of DOC and EEM intensities for the freshly-amended soil, PARAFAC analyses indicated no changes in DOM's fluorophore compositions after two years of ageing. The identified DOM components (C1 and C2) showed similar dynamics with the DOCs in responding to the rainfalls. On the other hand, total flux of DOM leaching from biochar-amended plots during three monitored storms was on average 59% higher than the control (p > 0.05), whereas DOM export via surface runoff was slightly diminished. Noticeably, biochar amendment had caused a significant increase of >1000 MUm macropores and thus the enhanced infiltration of soil water. Such changes led to increased flow discharge, which in turn resulted in elevated leaching of organic carbon during rainfalls. The results therefore implies that changes of soil structure and hydraulic properties that will take place after biochar application merits attention as they may play a continuous role in influencing the transport of DOM and possibly other solutes via runoff processes.

AB - This study assesses the sediment quality of the Guadalquivir River watercourse between the Alcala del Rio dam and the city of Seville. The main objective of this work is to address sediment quality in the area using an integrative approach that links sediment contamination and toxicity using the Asiatic clam (Corbicula fluminea) under field conditions. This is the first study conducted in the area that use of a battery of biomarkers from exposure (GST, GPx) to adverse biological effect (DNA and histopathological damage) to identify the contamination adverse effects in a river area affected by a cocktail of different anthropogenic activities (urban, industrial, agricultural, etc.). The sediment quality characterized in the area shows a significant biological stress related to metal(loid)s at station located in Alcala del Rio in the river upper part of the studied area, being this stress toxic when approaching the city of Seville. The sediments located nearby this city showed toxicity by means of positive values in the biomarkers of effects measured in the caged clams and related to contaminants with an industrial and urban discharge origins. These results have shown the useful and strength of the biomarker approach used in this study that combines biomarker responses from exposure to effects and allows identifying the contamination adverse effects by means of using caging individuals of the Asian clam. It has been proved in the different experiments how once the exposure biomarkers reach a maximum value of their system the detoxification ability of the organisms is collapsed and then the biomarkers of effect are measured significantly in the different tissues. The use of field surveys using tolerant specie such as the Asian clam is recommendable to determine sediment quality under an integrative point of view as here reported. PMID- 30290343 TI - Characteristics, sources, water quality and health risk assessment of trace elements in river water and well water in the Chinese Loess Plateau. AB - Water resources and water quality are restrictive factors in the Chinese Loess Plateau (CLP), a unique area with most severe soil erosion, fragile ecology and water shortage. River and well water samples were firstly analyzed, and multiple methods and indexes, including principal component analysis (PCA), correlation analysis (CA), sodium adsorption ratio (SAR), water quality index (WQI), hazard quotient (HQ), and hazard index (HI), were used to investigate characteristics, water quality and health risk assessment of trace elements in CLP. The average trace elements concentrations were higher than the world average with a slightly alkaline characteristic. PCA and CA showed that Al, Fe, Li, B, As, and F had natural origins from loess weathering and leaching; Cr, Pb, Cd, Cu, Ag, and Tl were mainly from anthropogenic input; Co, Ni, and Mn were dominated by both anthropogenic and natural sources. The poor river water quality was mainly related with high sodium (alkalinity) and salinity hazard. The poor well water quality samples with high WQI values, especially for As, Cr, and B, were distributed in the northwest and the Fenhe River sub-basin. The pollution level of trace elements in rivers in CLP was in medium level compared with other rivers worldwide. Arsenic pollution was the worst in well water and was the potential pollutant in river water especially for children. Arid climate together with anthropogenic input and special water characteristics (high Na, pH, and low Ca) aggravated As pollution. More work should be done to monitor the secular variation and remove As in the high As areas. The results of this study can provide the basic data for efficient water management and human health protection in CLP. PMID- 30290344 TI - Organ-specific differences in mercury speciation and accumulation across ringed seal (Phoca hispida) life stages. AB - Methylmercury (MeHg) is a central nervous system toxicant and exposures can adversely affect the health of marine mammals. Mercuric selenide (HgSe) in marine mammal tissues is hypothesized to result from a protective detoxification mechanism, but toxicokinetic processes contributing to its formation are poorly understood. Here, new data is reported on speciated Hg concentrations in multiple organs of n = 56 ringed seals (Phoca hispida) from Labrador, Canada, and compare concentrations to previously published data from Greenland seals. A higher proportion of Hg is found to accumulate in the kidney of young-of-the-year (YOY) ringed seals compared to adults. A toxicokinetic model for Hg species is developed and evaluated to better understand factors affecting variability in Hg concentrations among organs and across life stages. Prior work postulated that HgSe formation only occurs in the liver of mature seals, but model results suggest HgSe formation occurs across all life stages. Higher proportions of HgSe in mature seal livers compared to YOY seals likely results from the slow accumulation and elimination of HgSe (total body half-life = 500 days) compared to other Hg species. HgSe formation in the liver reduces modeled blood concentrations of MeHg by only 6%. Thus, HgSe formation may not substantially reduce MeHg transport across the blood-brain barrier of ringed seals, leaving them susceptible to the neurotoxic effects of MeHg exposure. PMID- 30290345 TI - What are the impacts of demographic structure on CO2 emissions? A regional analysis in China via heterogeneous panel estimates. AB - This study comprehensively investigated the impacts of demographic structure on CO2 emissions in China at the national level and the regional level for the first time. Panel cointegration modeling was employed to test the long-run relationships between CO2 emissions and six demographic structure variables, namely, dependency ratio, sex ratio, higher education ratio, industrial employment ratio, urbanization ratio, and average household size. The fully modified ordinary least squares method was then applied to estimate the long-run elasticity of CO2 emissions for the six demographic structure variables. The results suggested that long-run relationships between CO2 emissions and demographic structure existed at both the national level and the regional level. Dependency ratio was found to exert negative effects on CO2 emissions in China and its three sub-regions. Positive associations between sex ratio and CO2 emissions were revealed to exist in China and West China, and CO2 emissions elasticity for sex ratio was relatively high in West China. Higher education ratio had a positive effect on CO2 emissions in East China. Industrial employment ratio was found to positively correlate with CO2 emissions in China, East China, and Central China. Urbanization ratio was demonstrated to increase CO2 emissions at the national level and the regional level, and CO2 emissions elasticity for urbanization ratio decreased from West China to Central China, and then to East China. Negative correlations between average household size and CO2 emissions were detected at both the national level and the regional level. Based on the findings of this study, several practical recommendations were proposed, including optimizing age structure, promoting gender equality, advocating low carbon lifestyles and low-carbon consumption patterns, promoting industrial upgrading and industrial structure optimization, building low-carbon cities and less carbon-intensive public infrastructure systems, and improving residential energy efficiency. PMID- 30290346 TI - Effects of water deficit stress on agronomic and physiological responses of rice and greenhouse gas emission from rice soil under elevated atmospheric CO2. AB - Rice is the foremost staple food in the world, safeguarding the global food and nutritional security. Rise in atmospheric carbon dioxide (CO2) and water deficits are threatening global rice productivity and sustainability. Under real field conditions these climatic factors often interact with each other resulting in impacts that are remarkably different compared to individual factor exposure. Rice soils exposed to drought and elevated CO2 (eCO2) alters the biomass, diversity and activity of soil microorganisms affecting greenhouse gas (GHG) emission dynamics. In this review we have discussed the impacts of eCO2 and water deficit on agronomic, biochemical and physiological responses of rice and GHGs emissions from rice soils. Drought usually results in oxidative stress due to stomatal closure, dry weight reduction, formation of reactive oxygen species, decrease in relative water content and increase in electrolyte leakage at almost all growth and developmental phases of rice. Elevated atmospheric CO2 concentration reduces the negative effects of drought by improving plant water relations, reducing stomatal opening, decreasing transpiration, increasing canopy photosynthesis, shortening crop growth period and increasing the antioxidant metabolite activities in rice. Increased scientific understanding of the effects of drought and eCO2 on rice agronomy, physiology and GHG emission dynamics of rice soil is essential for devising adaptation options. Integration of novel agronomic practices viz., crop establishment methods and alternate cropping systems with improved water and nutrient management are important steps to help rice farmers cope with drought and eCO2. The review summarizes future research needs for ensuring sustained global food security under future warmer, drier and high CO2 conditions. PMID- 30290347 TI - NDVI-based vegetation dynamics and its response to climate changes at Amur Heilongjiang River Basin from 1982 to 2015. AB - Vegetation in Northern Hemisphere, being sensitive to climate change, plays an important role in the carbon cycles between land and the atmosphere. The response of vegetation to climate change was analyzed at pixel, biome and regional scale in Amur-Heilongjiang River Basin (AHRB) for growing season, spring, summer and autumn using Normalized Difference Vegetation Index and gridded climate data for the period 1982-2015. NDVI and climate variables trend detection methods and correlation analysis were applied. The potential impacts of human activities on growing season NDVI dynamics were investigated further using residual trend analysis. Results showed that at river basin scale, growing season vegetation experienced a discontinuous greening trend with two reversals, demonstrating that NDVI initially increased to mid-1990s, then declined to mid-2000s, and finally rebounded to 2015. This may be attributed to the shifting between drought and wet trends, indicating growing season NDVI was mainly regulated by precipitation. Temperature was the dominant factor on affecting spring vegetation growth while autumn NDVI showed negative correlation with precipitation due to the relation of precipitation with sunshine hours available for photosynthesis. The response of vegetation growth to climatic variations varied among vegetation types. Grassland NDVI exhibited positive correlation with precipitation in all time ranges. NDVI of needleleaved forest, broadleaved forest, mixed forest and woodland were positively correlated with temperature in all seasons, while showing significant negative correlation with autumn precipitation. Residual trend analysis revealed that human activities might lead to the vegetation degradation in China farming zone of AHRB. Fires also play an important role in regulating vegetation dynamics in the region. Results of our analysis can be used by national governments from three countries of AHRB in managing and negotiating vegetation resources of the region. PMID- 30290348 TI - Hepatorenal protective effects of taurine and N-acetylcysteine against fipronil induced injuries: The antioxidant status and apoptotic markers expression in rats. AB - Fipronil (FPN), a commonly used phenylpyrazole pesticide can induce oxidative tissue damage following hazard usage. Due to the extensive household and commercial usage of FPN, its toxic effects on mammals received considerable attention. Finding the proper antioxidant that can overcome FPN-induced damage is essential. Therefore, the present study aimed to assess the hepatorenal ameliorative outcomes of N-acetyl cysteine (NAC) and taurine (TAU) against hepatorenal damage induced by FPN in male Wistar rats. Compared to control rats, oral FPN (at a dose of 19.4 mg kg-1 BW for five successive days) significantly increased serum activities (p <= 0.05) of alkaline phosphatase, lactate dehydrogenase and transaminases, in addition to total cholesterol, urea and creatinine levels. Moreover, FPN provoked oxidative damage indicated by increased malondialdehyde and nitric oxide formation and decreased glutathione concentration and activities of enzymatic antioxidants (superoxide dismutase, glutathione peroxidase and catalase) in the hepatic and renal tissues. Furthermore, FPN administration induced overexpression of the proapoptotic (Bax), while it downregulated the expression of the anti-apoptotic (Bcl-2) protein. Interestingly, oral administration of TAU (50 mg Kg-1 BW) and NAC (50 mg Kg-1 BW), alone or in combination, five days prior to and five days along with FPN administration, significantly ameliorated (p <= 0.05) and normalized the harmful effects of FPN on serum biomarkers of hepatorenal injury, lipid peroxidation and tissue antioxidants. In conclusion, TAU and NAC, alone or in combination, provided significant hepatorenal protection against oxidative stress and apoptosis induced by FPN. PMID- 30290349 TI - Deriving nutrient criteria to support 'good' ecological status in European lakes: An empirically based approach to linking ecology and management. AB - European water policy has identified eutrophication as a priority issue for water management. Substantial progress has been made in combating eutrophication but open issues remain, including setting reliable and meaningful nutrient criteria supporting 'good' ecological status of the Water Framework Directive. The paper introduces a novel methodological approach - a set of four different methods - that can be applied to different ecosystems and stressors to derive empirically based management targets. The methods include Ranged Major Axis (RMA) regression, multivariate Ordinary Least Squares (OLS) regression, logistic regression, and minimising the mismatch of classifications. We apply these approaches to establish nutrient (nitrogen and phosphorus) criteria for the major productive shallow lake types of Europe: high alkalinity shallow (LCB1; mean depth 3-15 m) and very shallow (LCB2; mean depth < 3 m) lakes. Univariate relationships between nutrients and macrophyte assessments explained 29-46% of the variation. Multivariate models with both total phosphorus (TP) and total nitrogen (TN) as predictors had higher R2 values (0.50 for LCB1 and 0.49 for LCB2) relative to the use of TN or TP singly. We estimated nutrient concentrations at the boundary where lake vegetation changes from 'good' to 'moderate' ecological status. LCB1 lakes achieved 'good' macrophyte status at concentrations below 48-53 MUg/l TP and 1.1-1.2 mg/l TN, compared to LCB2 lakes below 58-78 MUg/l TP and 1.0-1.4 mg/l TN. Where strong regression relationships exist, regression approaches offer a reliable basis for deriving nutrient criteria and their uncertainty, while categorical approaches offer advantages for risk assessment and communication, or where analysis is constrained by discontinuous measures of status or short stressor gradients. We link ecological status of macrophyte communities to nutrient criteria in a user-friendly and transparent way. Such analyses underpin the practical actions and policy needed to achieve 'good' ecological status in the lakes of Europe. PMID- 30290350 TI - Ecotoxicity of the lipid-lowering drug bezafibrate on the bioenergetics and lipid metabolism of the diatom Phaeodactylum tricornutum. AB - Pharmaceutical residues impose a new and emerging threat to the marine environment and its biota. In most countries, ecotoxicity tests are not required for all pharmaceutical residues classes and, even when mandatory, these tests are not performed using marine primary producers such as diatoms. These microalgae are among the most abundant class of primary producers in the marine realm and key players in the marine trophic web. Blood-lipid-lowering agents such as bezafibrate and its derivatives are among the most prescribed drugs and most frequently found human pharmaceuticals in aquatic environments. The present study aims to investigate the bezafibrate ecotoxicity and its effects on primary productivity and lipid metabolism, at environmentally relevant concentrations, using the model diatom Phaeodactylum tricornutum. Under controlled conditions, diatom cultures were exposed to bezafibrate at 0, 3, 6, 30 and 60 MUg L-1, representing concentrations that can be found in the vicinity of discharges of wastewater treatment plants. High bezafibrate concentrations increased cell density and are suggested to promote a shift from autotrophic to mixotrophic metabolism, with diatoms using light energy generated redox potential to breakdown bezafibrate as carbon source. This was supported by an evident increase in cell density coupled with an impairment of the thylakoid electron transport and consequent photosynthetic activity reduction. In agreement, the concentrations of plastidial marker fatty acids showed negative correlations and Canonical Analysis of Principal coordinates of the relative abundances of fatty acid and photochemical data allowed the separation of controls and cells exposed to bezafibrate with high classification efficiency, namely for photochemical traits, suggesting their validity as suitable biomarkers of bezafibrate exposure. Further evaluations of the occurrence of a metabolic shift in diatoms due to exposure to bezafibrate is paramount, as ultimately it may reduce O2 generation and CO2 fixation in aquatic ecosystems with ensuing consequences for neighboring heterotrophic organisms. PMID- 30290351 TI - Differences of cell surface characteristics between the bacterium Pseudomonas veronii and fungus Ophiostoma stenoceras and their different adsorption properties to hydrophobic organic compounds. AB - The first step of microbial biodegradation is the adsorption of pollutants on the microorganisms' surface, which is determined by the microorganism type and pollutant hydrophobicity. One fungus Ophiostoma stenoceras LLC and one bacterium Pseudomonas veronii ZW were chosen for the investigation of cell surface hydrophobicity and adsorption abilities to various organic compounds. Results showed that the fungus could better capture and adsorb organic compounds in liquid and gas phases, and the adsorption was a physical monolayer adsorption process. Much smaller partition coefficient for gas-fungus suggested that direct gaseous adsorption was preferred. The XPS (X-ray photoelectron spectroscopy) characterization further confirmed that several functional groups changed after the adsorption of compounds. The time taken for complete degradation of hexane, tetrahydrofuran and chlorobenzene was shorter with the addition of O. stenoceras LLC. Such findings are useful in exploring the special cell surface of fungus in adsorption and bioenhancement for organic treatment of organic contaminants using bacteria. PMID- 30290352 TI - The value of information: Realising the economic benefits of mapping seagrass meadows in the British Virgin Islands. AB - Carbon capturing coastal and marine habitats around the world are decreasing in extent every year, habitats found in abundance in Small Island Developing States' territories. However, these habitats are under threat by increased levels of economic activities and extreme weather events. Consequently, as those ecosystems become scarce their value is expected to increase. In this paper the "value of information", the increase in knowledge that renders a system or a function more valuable, from marine habitat mapping is presented through the (monetary) valuation of one regulating service provided by the newly mapped habitats. Mapping a section of a channel with a multibeam echosounder revealed more seagrass resources than in previous studies. Using values for both the Social Cost of Carbon and Abatement Cost methods, from the literature we estimate the value of the carbon sequestration and storage service these seagrass meadows provide. The impacts of hurricanes in the newly mapped seagrasses were also investigated. Despite the costs of mapping, monitoring and of projected losses of ecosystem services provision due to hurricanes, net benefits over a time period of 50 years were considerably larger. The new information provided highlights carbon capturing habitats as more important, enabling the "value of information" to inform policymaking. PMID- 30290353 TI - Free phenolic compounds in waters of the Ross Sea. AB - The presence of free phenolic compounds (PC) in Antarctic sea water has been investigated to explain their source and particle size distribution in the atmospheric aerosols, as determined in our previous research. The sea water samples were filtered to distinguish the PC concentrations in the particulate and dissolved fractions. Two sample preparation procedures were developed to quantify nine PC in both fractions. The highest concentrations were found in the dissolved fraction of Ross Sea water, with vanillin, vanillic acid, acetovanillone and p coumaric acid being the most abundant PC. Dissolved PC were mainly found in the upper part of water column. This facilitated the sea water-air exchange by bubble busting processes. In the aerosol, they were mainly found in the fine fraction, where these compounds have a higher degree of oxidation than PC detected in seawater, suggesting that they were newly emitted and they have been not yet oxidized. These results supported our previous hypothesis that PC were locally emitted into the atmosphere from the Ross Sea. Three different possible sources of PC are hypothesized for Antarctic sea waters: 1) from the intrusion of Modified Circumpolar Deep Water that may transport oceanic lignin; 2) from phytoplankton biomass that may be a source of PC in Antarctic waters since diatoms produce exudates that contain vanillic acid, p-coumaric acid and syringic acid; 3) from the melting of glaciers and sea ice: glaciers contain lignin that can be degraded, while in the sea ice there are diatoms that may release PC. Statistical analysis and the low value of vanillic acid/vanillin ratio indicated that the most plausible source for PC in the dissolved fraction was the senescence of phytoplankton. As a contrast, particulate PC with higher vanillic acid/vanillin ratios were ascribed to degraded lignin or the sorption of diagenically oxidized material on particles. PMID- 30290354 TI - Stable isotope analyses revealed the influence of foraging habitat on mercury accumulation in tropical coastal marine fish. AB - Bioaccumulation of toxic metal elements including mercury (Hg) can be highly variable in marine fish species. Metal concentration is influenced by various species-specific physiological and ecological traits, including individual diet composition and foraging habitat. The impact of trophic ecology and habitat preference on Hg accumulation was analyzed through total Hg concentration and stable isotope ratios of carbon (delta13C) and nitrogen (delta15N) in the muscle of 132 fish belonging to 23 different species from the Senegalese coast (West Africa), where the marine ecosystem is submitted to nutrient inputs from various sources such as upwelling or rivers. Species-specific ecological traits were first investigated and results showed that vertical (i.e. water column distribution) and horizontal habitat (i.e. distance from the coast) led to differential Hg accumulation among species. Coastal and demersal fish were more contaminated than offshore and pelagic species. Individual characteristics therefore revealed an increase of Hg concentration in muscle that paralleled trophic level for some locations. Considering all individuals, the main carbon source was significantly correlated with Hg concentration, again revealing a higher accumulation for fish foraging in nearshore and benthic habitats. The large intraspecific variability observed in stable isotope signatures highlights the need to conduct ecotoxicological studies at the individual level to ensure a thorough understanding of mechanisms driving metal accumulation in marine fish. For individuals from a same species and site, Hg variation was mainly explained by fish length, in accordance with the bioaccumulation of Hg over time. Finally, Hg concentrations in fish muscle are discussed regarding their human health impact. No individual exceeded the current maximum acceptable limit for seafood consumption set by both the European Union and the Food and Agriculture Organization of the United Nations. However, overconsumption of some coastal demersal species analyzed here could be of concern regarding human exposure to mercury. PMID- 30290355 TI - Assessing microbial contamination and antibiotic resistant bacteria using zebra mussels (Dreissena polymorpha). AB - Aquatic pollution with faecal bacteria and subsequent consumption of contaminated water or food is a worldwide issue that causes severe health effects (e.g. meningitis, salmonellosis, dysentery). In addition, the excessive use of antibiotics in animal husbandry and human medicine has enhanced the selective pressure on pathogenic bacteria, further increasing human health risks and detrimental effects on natural microbial communities. This urges the need to monitor faecal contamination using a time-integrated approach, as grab water samples can miss pathogen peaks. We tested the ability of zebra mussels (Dreissena polymorpha) to take up and depurate faecal indicator bacteria such as Escherichia coli and intestinal enterococci. Furthermore, we quantified the frequency of antibiotic resistant bacteria in water and mussels both in controlled laboratory tests and under in situ conditions downstream of a sewage treatment plant (STP). Laboratory results show that bacterial indicators in mussels were 132 times higher than their concentration in water, and that mussels retained bacteria up to 2 days after pulse exposure. Field results show decreasing bacterial concentrations in both water and mussels downstream the STP, with maximum E. coli concentrations ranging 173-9 cfu mL-1 in water and 2970-330 cfu g-1 in mussels. Similarly, enterococci ranged 59-4 cfu mL-1 and 1450-240 cfu g-1 in water and mussels, respectively. High proportions of antibiotic resistant E. coli were found in mussels (72%) and water (65%), and slightly lower proportion of resistant enterococci was found in mussels (47%) and in water (34%). Moreover, 33% of the bacteria isolated from mussels were resistant to multiple antibiotics, which emphasizes that resistance is a common feature in surface waters and highlights the need for safe water management. Our results show that zebra mussels provide an efficient, time-integrating tool for quantifying faecal indicators, including resistant and multidrug resistant bacteria. PMID- 30290356 TI - Linking bioavailability and toxicity changes of complex chemicals mixture to support decision making for remediation endpoint of contaminated soils. AB - A six-month laboratory scale study was carried out to investigate the effect of biochar and compost amendments on complex chemical mixtures of tar, heavy metals and metalloids in two genuine contaminated soils. An integrated approach, where organic and inorganic contaminants bioavailability and distribution changes, along with a range of microbiological indicators and ecotoxicological bioassays, was used to provide multiple lines of evidence to support the risk characterisation and assess the remediation end-point. Both compost and biochar amendment (p = 0.005) as well as incubation time (p = 0.001) significantly affected the total and bioavailable concentrations of the total petroleum hydrocarbons (TPH) in the two soils. Specifically, TPH concentration decreased by 46% and 30% in Soil 1 and Soil 2 amended with compost. These decreases were accompanied by a reduction of 78% (Soil 1) and 6% (Soil 2) of the bioavailable hydrocarbons and the most significant decrease was observed for the medium to long chain aliphatic compounds (EC16-35) and medium molecular weight aromatic compounds (EC16-21). Compost amendment enhanced the degradation of both the aliphatic and aromatic fractions in the two soils, while biochar contributed to lock the hydrocarbons in the contaminated soils. Neither compost nor biochar affected the distribution and behaviour of the heavy metals (HM) and metalloids in the different soil phases, suggesting that the co-presence of heavy metals and metalloids posed a low risk. Strong negative correlations were observed between the bioavailable hydrocarbon fractions and the ecotoxicological assays suggesting that when bioavailable concentrations decreased, the toxicity also decreased. This study showed that adopting a combined diagnostic approach can significantly help to identify optimal remediation strategies and contribute to change the over conservative nature of the current risk assessments thus reducing the costs associated with remediation endpoint. PMID- 30290357 TI - Summer is in winter: Disturbance-driven shifts in macroinvertebrate communities following hydroelectric power exploitation. AB - In Alpine streams, humans have strongly modified the interactions between hydraulic processes, geomorphology and aquatic life through dams, flow abstraction at water intakes and river channel engineering. To mitigate these impacts, research has addressed both minimum flows and flow variability to sustain aquatic ecosystems. Whilst such environmental flows might work downstream of dams, this may not be the case for water intakes. Intakes, generally much smaller than dams, are designed to abstract water and to leave sediment behind. Sediment accumulation then results in the need to flush intakes periodically, often more frequently than daily in some highly glaciated basins. Sediment delivery downstream is then maintained through short duration floods with very high sediment loads. Here we tested the hypothesis that sediment flushing, and the associated high frequency of bed disturbance, controls in-stream habitat and macroinvertebrate assemblages. We collected macroinvertebrates over a 17-month period from an Alpine stream as well as a set of lateral unperturbed tributaries that served as controls. In contrast to established conceptual models, our results showed that the stream is largely void of life during summer, but that populations recover rapidly as the frequency of intake flushing falls in early autumn, producing richer and larger populations in winter and early spring. The recovery in autumn may be due to the recruitment of individuals from tributaries. We conclude that intake flushing in summer inverts expected summer-winter macroinvertebrate abundances, and questions the extent to which environmental flows in intake-impacted Alpine streams will lead to improvements in instream macrofauna unless sediment also is managed. PMID- 30290358 TI - LC-HRMS suspect screening to show spatial patterns of New Psychoactive Substances use in Australia. AB - New Psychoactive Substances (NPS) are an ever-changing class of compounds designed to imitate the effects of current recreational drugs. Such a diverse market is difficult to assess by traditional means, while collected information can become obsolete before it is available. Wastewater-based epidemiology is one technique which can capture information on where and when NPS appear at the community level. The aim of this study was to identify NPS in wastewater samples using a suspect screening approach. Weekend samples were collected from 50 wastewater treatment plants from Australian capital cities and regional areas across all eight States and Territories and screened against a database containing almost 200 NPS. A total of 22 different NPS were found across all regional and metropolitan wastewater treatment plants. Results showed that the most detected compounds were of the cathinone class, with both Alpha-PVP and methcathinone found in every region. In addition, five different synthetic cannabinoids were detected, at least once in half of the regions analysed. Herein, we report the first comprehensive nationwide analysis of NPS and show the utility of liquid chromatography-high resolution mass spectrometry screening for delivering spatial information of the NPS being consumed in communities. PMID- 30290359 TI - Using survival analysis to predict septic shock onset in ICU patients. AB - PURPOSE: To determine the efficacy of survival analysis for predicting septic shock onset in ICU patients. MATERIALS AND METHODS: We performed a retrospective analysis on ICU cases from Mercy Hospital St. Louis from 2012 to 2016. As part of the procedure for inclusion in the Apache Outcomes database, each case is reviewed by critical care clinicians to identify septic shock patients as well as the time of septic shock onset. We used survival analysis to predict septic shock onset in these cases and employed lagging to compensate for uncertainties in septic shock onset time. RESULTS: Survival analysis was highly effective at predicting septic shock onset, producing AUC values of >0.87. The methodology was robust to lag times as well as the specific method of survival analysis used. CONCLUSIONS: This methodology has the potential to be implemented in the ICU for real time prediction and can be used as a building block to expand the approach to other hospital wards or care environments. PMID- 30290360 TI - Microcystin-LR exposure induced nephrotoxicity by triggering apoptosis in female zebrafish. AB - Recently, several studies showed that microcystin-LR (MCLR) can accumulate and induce toxicity in kidney. However, the exact mechanism is unknown. The aim of this study was to explore the mechanism of MCLR-induced nephrotoxicity. To this end, adult zebrafish were exposed to MCLR (0, 1, 5 and 25 MUg/L) for 60 days. Exposure to MCLR caused histopathological lesions, which were characterized by renal tubules filled with eosinophilic casts, abnormal renal tubules, intertubular space decrease, and blood infiltration in renal cells. RNA-Seq analysis indicated that exposure to MCLR significantly interfered with renal gene expressions, and these genes were enriched in various pathways, such as oxidative phosphorylation, cell cycle, and protein processing in endoplasmic reticulum, which were related to apoptosis. Furthermore, terminal deoxynucleotide transferase-mediated deoxy-UTP nick end labelling (TUNEL) assay showed that MCLR exposure induced renal cell apoptosis. In addition, negative changes of the reactive oxygen species (ROS) level as well as apoptotic-related gene, protein expressions and enzyme activities suggested that MCLR could induce production of ROS, subsequently triggering apoptosis via p53-bcl-2 and caspase-dependent pathway in the kidney of zebrafish. Therefore, it can be concluded that apoptosis is a primary case of MCLR-induced nephrotoxicity.

AB - Arsenic (As), a non-threshold class I carcinogen, is a main source of human exposure to inorganic As for billions of people worldwide. Rice is much more effectual in accruing As into its grain and other parts. Therefore, strategies to reduce As accumulation in rice should be adopted. The impact of water [Alternate Wetting and Drying (AWD), incessant flooding (CF)] and fertilizer management [Silicon (Si@ control, 10 and 20 mg/kg soil) and Phosphorus (P@ control, 12.5 and 25.0 mg/kg soil)] on the bioaccumulation of As in rice plants under different As graded paddy soils (control, 10, 20 mg/kg) using an Australian rice variety (cv. Sherpa) was investigated under greenhouse conditions. Results indicated that, arsenite accounted for >80% of the total inorganic As in pore water and total As concentration declined from 933 MUg/L to 177 MUg/L with time. AWD irrigation practice with Si fertilization significantly reduced the total As levels in pore water. Arsenic concentration in different rice plant tissues showed significant variations due to water and fertilizer management. Lower concentrations of As in rice grains were observed using AWD (average 93.0 MUg/kg) than those observed in CF (average 121 MUg/kg) irrigation practice. The addition of Si also significantly (p < 0.03) decreased As uptake by rice plants while adding of P has no significant effect and this is also true for Si and P interaction. AWD irrigation practice with Si fertilization resulted in a reduction of grain As level at around 12%-21%, while grain yield increased by 13%.

AB - The non-proteinogenic amino acid beta-N-methylamino-l-alanine (BMAA) is associated with the development of neurodegenerative diseases such as Alzheimer's disease, amyotrophic lateral sclerosis/parkinsonism-dementia complex (ALS-PDC) and amyotrophic lateral sclerosis. BMAA is known to induce neurotoxic effects leading to neurodegeneration via multiple mechanisms including misfolded protein accumulation, glutamate induced excitotoxicity, calcium dyshomeostasis, endoplasmic reticulum stress and oxidative stress. In the present study, for the first time, genotoxic activity of BMAA (2.5, 5, 10 and 20 MUg/mL) was studied in human peripheral blood cells (HPBCs) using the comet and cytokinesis-block micronucleus cytome assays. In addition, the influence of BMAA on the oxidative stress was assessed. At non-cytotoxic concentrations BMAA did not induce formation of DNA strand breaks in HPBCs after 4 and 24 h exposure; however, it significantly increased the number of micronuclei after 24 and 48 h at 20 MUg/mL and nucleoplasmic bridges after 48 h at 20 MUg/mL. The frequency of nuclear buds was slightly though non-significantly increased after 48 h. Altogether, this indicates that in HPBCs BMAA is clastogenic and induces complex genomic alterations including structural chromosomal rearrangements and gene amplification. No influence on oxidative stress markers was noticed. These findings provide new evidence that environmental neurotoxin BMAA, in addition to targeting common pathways involved in neurodegeneration, can also induce genomic instability in non-target HPBCs suggesting that it might be involved in cancer development. Therefore, these data are important in advancing our current knowledge and opening new questions in the understanding of the mechanisms of BMAA toxicity, particularly in the context of genotoxicity.

AB - PURPOSE: Residential immersive life skills programs provide youth with the skills and outlooks needed to adopt new roles in life. Observed program opportunities and service providers' perceptions of opportunities were examined to determine program fidelity. Service providers' views of how the programs work were also examined. METHOD: 107 activity settings were observed across two summers at three programs, with opportunities assessed using the Measure of Environmental Qualities of Activity Settings (MEQAS-48). Activity settings were classified by session format (instructional versus experiential) and activity type (active physical, skill-based, self-improvement). Qualitative interviews were held with seven service providers. RESULTS: Service providers indicated the importance of life-preparatory learning opportunities for social interaction, choice, and skill development, which aligned with high observed MEQAS-48 opportunities for social interaction, choice in experiential session formats, and personal growth. Providers individualized program delivery to provide youth with personally meaningful and challenging experiences. Providers also discussed emergent, transformational outcomes, including enhanced awareness of strengths, enhanced confidence in skills, identity development, and greater awareness of future life possibilities. CONCLUSIONS: The study provided evidence of program fidelity, along with robust evidence for program opportunities as an active ingredient that may be transferable to the design and delivery of other transition-support programs. PMID- 30290363 TI - Creating and sustaining cooperative relationships between supervised injection services and police: A qualitative interview study of international stakeholders. AB - BACKGROUND: Supervised injection services (SIS) operate with special exemptions from drug law enforcement. Given the expansion of SIS and the opioid overdose crisis in numerous jurisdictions, now is a critical time to examine factors that contribute to cooperative SIS-police relationships. We sought to learn about SIS police relationships from international jurisdictions with well-established as well as newer SIS. METHODS: We conducted 16 semi-structured telephone interviews with SIS managers (n = 10) and police liaisons (n = 6) from 10 cities in seven different countries (Australia, Canada, Denmark, France, Germany, Netherlands, and Spain). All participants provided informed consent. We focused our coding and analysis on themes that emerged from the data. RESULTS: Five key contributors to cooperative SIS-police relationships emerged from the data: early engagement and dialogues; supportive police chiefs; dedicated police liaisons; negotiated boundary agreements; and regular face-to-face contact. Most participants perceived the less formalised, on-the-ground approach to relationship-building between police and SIS adopted in their city to be working well in general. SIS managers and police participants reported a lack of formal police training on harm reduction, and some thought that training was unnecessary given the relatively positive local SIS-police relationships they reported. CONCLUSION: Our qualitative study provides new, in-depth empirical examples of how police in varied international jurisdictions can come to accept and work cooperatively with, not against, SIS staff and clients. Investing ongoing effort in SIS-police relationships, in a manner that best suits local needs, may hold greater and more sustainable public health value than delivering specific curricula to police. PMID- 30290365 TI - Toxin diversity revealed by the venom gland transcriptome of Pardosa pseudoannulata, a natural enemy of several insect pests. AB - The pond wolf spider, Pardosa pseudoannulata, is one of the most dominant predators of several agriculture insect pests including mainly the rice planthoppers and leafhoppers in paddy fields in Asia. Venom has been an attractive subject as the powerful weapon of spiders due to the complex components secreted from venom gland. The transcriptome of P. pseudoannulata venom gland was sequenced in order to understand the diversity of venom components at the molecular level and provide a new perspective for insect pest management. A total of 48 potential peptide toxins were identified from 75,980 assembled transcripts. Among them, 32 putative neurotoxin precursors were classified into six families systematically. In addition to neurotoxins, peptide toxins with potential antiviral and antifungal activities were annotated as well as the protease inhibitors. The diversity of P. pseudoannulata venom was firmly demonstrated with the presence of astacin-like metalloprotease toxins, Kunitz type serine protease inhibitors, venom allergen 5, hyaluronidase and other important venom components. In addition, the tissue expression profiles of the toxin-related genes were investigated in venom gland, brain, and fat body. The present study classified the diverse venom components P. pseudoannulata and provided essential information of potential insecticidal toxins for the biological control of insect pests. PMID- 30290366 TI - Genome-wide identification of the entire 90 glutathione S-transferase (GST) subfamily genes in four rotifer Brachionus species and transcriptional modulation in response to endocrine disrupting chemicals. AB - Genome-wide identification of glutathione S-transferase (GST), a major phase II detoxification enzyme, was investigated in four different aquatic model rotifer species Brachionus koreanus, B. plicatilis, B. rotundiformis, and B. calyciflorus. GSTs are ubiquitous antioxidant enzymes that play versatile function including cellular detoxification, stress alleviation, and production of the radical conjugates. Among the four rotifers, B. rotundiformis was found with the least number of GST genes (total 19 GST genes), whereas the other three species shared 23 to 24 GST genes. Among the identified GST genes, belonging to the cytosolic GST superfamily, the expansion of GST sigma classes mainly occurs through tandem duplication, resulting in tandem-arrayed gene clusters on the chromosomes. Overall, the number of genes discovered in this study was highest in the sigma class, zeta, alpha, and omega in descending order. With integration of phylogenetic analysis and xenobiotic-mediated GST mRNA expression patterns along with previous enzymatic activities, the functional divergence among species specific GST genes was clearly observed. This study covers full identification of GST classes in three marine rotifer and one fresh-water rotifer species and their important role in marine environmental ecotoxicology. PMID- 30290367 TI - The influence of crouch gait on sagittal trunk position and lower lumbar spinal loading in children with cerebral palsy. AB - BACKGROUND: Crouch gait is a common pattern in children with CP. Little investigation has been performed as to the role of the trunk during crouch gait. A compensatory movement of the trunk may alter the position of the ground reaction force with the effect of reducing the moment arm about the knee or hip. While this may benefit these joints in the context of reduced loading, there may be implications further up the kinematic chain at the level of the lumbar spine. RESEARCH QUESTION: Are compensatory movements of the trunk present during crouch gait in children with CP and are levels of loading at the lower lumbar spine affected? METHODS: A full barefoot lower limb and trunk 3-dimensional kinematic and kinetic analysis, with kinetics estimated at the spinal position of L5/S1, was performed on 3 groups of children, namely CP Crouch, CP No-Crouch and TD. Differences in trunk position and L5/S1 loading were compared between groups. RESULTS: Mean trunk position in relation to the pelvis and laboratory was not statistically significant between groups. At the level of the spine, no differences were present in mean position between groups for L5/S1 sagittal moment or anterior/posterior force. SIGNIFICANCE: Crouch gait does not elicit a compensatory response of the trunk in children with CP and, consequently, reactive forces and moments at the lower lumbar spine remain within normal limits. With this in mind, it is unlikely that a crouch gait pattern will affect the health of the spine over time in these children. PMID- 30290368 TI - Isoliquiritigenin protects against blood-brain barrier damage and inhibits the secretion of pro-inflammatory cytokines in mice after traumatic brain injury. AB - Traumatic brain injury (TBI) caused by an external mechanical force acting on the brain is a serious neurological condition. Inflammation plays an important role in prolonging secondary tissue injury after TBI, leading to neuronal cell death and dysfunction. Isoliquiritigenin (ILG) is a flavonoid monomer with anti inflammatory characteristic. Thus, we had investigated the potential protective effects of ILG on TBI-induced injuries and identified the mechanisms underlying it. Here, we have demonstrated that ILG preserves blood brain barrier (BBB) integrity in vivo, suppresses the activation of microglia and inflammatory responses in mice after TBI, consequently leading to neurofunctional deficits, brain oedema, structural damage, and macrophage infiltration. In vitro, ILG exerts anti-inflammatory effect, and upregulates tight junction proteins 120-beta catenin and occludin in SH-SY5Y cells under oxygen glucose deprivation/reoxygenation (OGD/D) condition. Additionally, we found that PI3K/AKT/GSK-3beta signalling pathway is involved in ILG treatment for TBI. To further confirm it, we had used SC79 (ethyl 2-amino-6-chloro-4-(1-cyano-2-ethoxy 2-oxoethyl)-4H-chromene-3-carboxylate), an Akt specific activator, to activate Akt, we found that SC79 partially reduces the protective effect of ILG for TBI. Overall, our current study reveals the neuroprotective role of ILG on TBI-induced BBB damage, downregulated tight junction proteins via PI3K/AKT/GSK-3beta signalling pathway. Furthermore, ILG suppresses the secretion of pro-inflammatory cytokines after TBI through inhibiting the PI3K/AKT/GSK-3beta/NF-kappaB signalling pathway. Our findings suggest that GSK-3beta is a key regulatory factor during TBI-induced secretion of inflammatory cytokines, neuronal apoptosis and destruction of BBB. PMID- 30290369 TI - Rules to activate CD8+T cells through regulating subunits of opioid receptors by methionine enkephalin (MENK). AB - The goal of this work was to investigate how MENK could regulate the functions of CD8+T cells and to explore the relationship between this regulation and opioid receptor expression. Our results showed that the opioid receptors presented on the cell menbrane of CD8+T cells were MOR and DOR. MENK promoted the expression of opioid receptors as well as the elevation of the surface molecules such as CD28, PD-1, CTLA-4 and FasL and intracellular granzyme B. Selectively blocking the MOR by CTAP or DOR by NTI could result in inhibition of the corresponding CD8+T cells proliferation and the expressions of surface molecules. In addition, non-selectively blocking both MOR and DOR by NTX could further impair the functions and proliferation of CD8+T cells. Our currently data indicated that MENK could play a vital role in immune functions via precise regulation to subunits of opioid receptors.

PMID- 30290371 TI - Men's Participation and Performance in the Boston Marathon from 1897 to 2017. AB - This study examined men's participation and performance in the Boston Marathon. Data from all 368,940 official male finishers in the Boston Marathon from 1897 through 2017 were analyzed using different analyses and regression models for all runners, annual top hundred finishers, annual top ten finishers and annual winners. Effect of calendar year on race time was examined alone, in a uni variable model, and together with country of origin and weather conditions (average air temperature and precipitation) in a multi-variable model. The mean race time of all finishers increased across calendar years, in line with the participation, but it decreased when we considered the annual winners, 10 and 100 fastest. Kenyans and Ethiopians were the fastest nationalities (p<0.001) when we considered all finishers and the annual top 100 fastest but not when the annual 10 fastest were considered. Air temperature<=8 degrees C improved (p<0.001) race times compared to air temperature>8 degrees C. Precipitation (>0 mm) improved performance for the annual 100 fastest and annual 10 fastest (p=0.013-0.031) but not for all finishers. Our findings improved the knowledge about the evolution of male marathoners across calendar years, considering as main effects country of origin and particular weather conditions. PMID- 30290372 TI - Association of Monocarboxylate Transporter-1 (MCT1) A1470T Polymorphism (rs1049434) with Forward Football Player Status. AB - The aim of this study was to investigate the association between the MCT1 (monocarboxylate transporter 1) A1470T polymorphism and positional roles in a large cohort of professional football players from five different countries. We compared genotype distributions of the MCT1 A1470T polymorphism between football players (n=694) and non-athlete controls (n=781) from Italy, Poland, Lithuania, Ukraine and Malta, and we analyzed the MCT1 genotype distributions with respect to the players' positions in the field (e. g. forwards, midfielders, defenders and goalkeepers). Genomic DNA was extracted from either buccal epithelium or peripheral blood using a standard protocol. In the pooled cohort of Italian, Polish, Lithuanian and Ukrainian football players, forwards (n=148) were more likely than controls (n=781) to possess the A allele (chi2=7.067, p=0.029, FDR q value 0.116), with a greater likelihood of having the AA genotype compared with the TT genotype (OR=1.97; C.I.=1.07-3.64; p=0.021, FDR q value 0.086). The MCT1 AA genotype was significantly more frequent in forwards then in controls. Further studies are needed to confirm these findings in other professional football player cohorts. PMID- 30290373 TI - Plasma Steroids are Not Associated with Resting and Exercise Blood Pressure. AB - We investigated the associations between steroid hormones and resting and exercise blood pressure in the sedentary state and in response to an exercise program controlling for sex, body mass, ethnicity, age, oral contraceptives, hormone therapy, smoking and alcohol intake in subjects from the HERITAGE Family Study.: In the sedentary state, 267 men (28% Blacks) and 301 women (37% Blacks) were available, and 241 men and 254 women completed the exercise program. Fourteen steroid hormones and sex hormone-binding globulin concentrations were assayed in a fasted state. Statistical significance was set at a Bonferroni adjusted p<0.0001. After controlling for the various covariates, only testosterone came close to a significant correlation with exercise systolic blood pressure at 50 W (r=-0.21, P=0.0006) in men. No other correlations with resting and exercise blood pressure traits were found at baseline. There were significant changes in blood pressure in response to the exercise program, but none of the correlations with baseline plasma steroids reached statistical significance. Plasma steroids do not correlate with resting and exercise blood pressure in sedentary adults and do not associate with blood pressure changes in response to a 20-week endurance exercise program. PMID- 30290374 TI - Associations of the Force-velocity Profile with Isometric Strength and Neuromuscular Factors. AB - We aimed to explore relationships between the force-velocity (FV) profile and the isometric muscle torque performance during a knee extension task. The FV profile (force-intercept [F0], velocity-intercept [V0], maximum power [Pmax], and FV slope) during the countermovement jump (CMJ) exercise and isometric maximum voluntary torque (MVIC) and explosive voluntary torque production were assessed in 43 participants. Electromyography (EMG) was recorded during the isometric assessments and resting muscle architecture measurements were also performed (quadriceps thickness, vastus lateralis pennation angle and fascicle length). Pearson's correlation coefficients were computed to assess bivariate relationships between the FV profile, isometric torque, EMG activation and muscle architecture. F0 predictions from neuromuscular measurements were assessed through multiple linear regression. Associations of F0 and Pmax with isometric torque increased from explosive to MVIC torque (r>=0.47; P<0.05). Significant associations were found between muscle architecture and F0 and Pmax (r>=0.69; P<0.05), while V0 and FV slope were unrelated (r<=0.27; P>0.05). Quadriceps thickness and VL pennation angle explained ~62% of F0 variance. In conclusion, the knee extensors maximal isometric strength and their morphological architecture are strongly related to F0 estimated from a CMJ FV profile test.

AB - AIM OF THE STUDY: In order to develop an online portal for the preparation for inpatient psychosomatic rehabilitation, information requirements as well as the online use behavior of rehabilitants were determined first. METHODS: Four focus groups with rehabilitants (N=31) as well as two with the treatment team (N=18) were performed and evaluated qualitatively. RESULTS: A total of 419 statements by rehabilitants and 333 statements by the treatment team were coded and assigned to categories. Current information materials on rehabilitation have been regarded as too extensive and difficult to understand by rehabilitants. They were uncertain regarding the effectiveness and sustainability of the treatment. While practitioners assumed that rehabilitants expect wellness and relaxation during rehabilitation, rehabilitants themselves reported more of an active treatment orientation. CONCLUSION: Online portals for preparation should address the effectiveness and sustainability of psychosomatic rehabilitation by means of illustrative case studies. PMID- 30290376 TI - [Current Endoscopic Methods in Bariatric Surgery]. AB - The 2011 World Health Summit reported the epidemics of diabetes mellitus and morbid obesity. In Germany, 62.7% of the population have a BMI above 25 kg/m2 and 21.9% above 30 kg/m2. 10.5 patients per 100,000 inhabitants were treated with metabolic surgery, whereas in France 86.0 and in Sweden 114.8 patients per 100,000 inhabitants were given surgery. The development of endoscopic methods leads to the opportunity to bridge patients with a high risk profile before operation. Endoscopy is an excellent procedure with few complications. However, these methods need a selective and specialised concept of treatment. Endoscopy in metabolic surgery requires expertise in both endoscopy and in the techniques of metabolic surgery. The aim of the present paper is to report the new methods of endoscopy in the treatment of obese patients, on the basis of the literature and our own experience. PMID- 30290377 TI - Biological Actions, Electrical Conductance and Silicon-Containing Microparticles of Arsenicum Album Prepared in Plastic and Glass Vials. AB - INTRODUCTION: According to the "silica hypothesis" formulated to explain homeopathy, the information of starting materials would be transferred to cells by silica nanoparticles detached from the glassware walls by serial dilution and agitation through epitaxy. We compared the biological activity, electrical current and silicon microparticle content (by means of scanning electron microscopy/energy-dispersive X-ray spectroscopy) of high dilutions (HDs) of arsenic prepared in plastic and glass vials to investigate the role of silica in their biological effects in vitro. MATERIALS AND METHODS: Co-cultures of macrophages and yeast (Saccharomyces cerevisiae) were treated with different HDs of arsenic prepared in plastic and glass vials. Macrophage morphology, phagocytosis index, nitric oxide (NO), and cytokine production were evaluated. RESULTS: Measurable amounts of silicon microparticles were detected only in the HDs prepared in glass vials, but ultra-centrifugation eliminated them. Specific and non-specific results were observed. Non-specific pro-inflammatory effects were seen in all dilutions prepared in plastic vials, including elevation of pro inflammatory cytokines, NO and macrophage phagocytic index. Only the 200th centesimal dilution of arsenic produced specific decrease in interleukin-6 production in macrophages, and it was independent of the vial type or the presence of microparticles of silica in the medicine samples. The nature of the vials had an impact on the electric flow in the respective fluids. CONCLUSION: The non-specific, pro-inflammatory effects might be attributed to organic residuals detached from the vials' plastic walls during manipulation. Instead, specific silica-independent effects of the homeopathic medicine can be attributed to the decrease of interleukin-6 after treatment with the 200th centesimal dilution of arsenic. PMID- 30290378 TI - Electronic Registration in Complementary/Homeopathic Medical Practice with Identification of 'Best Homeopathic Cases': A Pilot Study. AB - BACKGROUND: Practice-based registration could identify 'general' and 'homeopathic' prognostic factors for therapeutic success in patients who seek complementary and alternative medicine (CAM)/homeopathic treatment. Identification of 'best homeopathic cases' within a database could inform clinical research and improve homeopathic practice. OBJECTIVE: To investigate the feasibility of registration in daily CAM/homeopathic practice, evaluate patient reported outcome measures and tools for identifying 'best homeopathic cases' and to make recommendations for an electronic database. METHODS: In 2015 and 2016, 25 homeopathic doctors registered details of a maximum of 20 patients each, with 6 months of follow-up (extended follow-up for 'best homeopathic cases'), in Excel or in the Homeopathic Administration and Registration Program (HARP) database. Informed consent was obtained from each patient. Patient-perceived change of main complaint was measured by a 7-point Likert scale. Best homeopathic cases were defined by treatment with one homeopathic medicine, >= 2 months of follow-up, result score +2 to +4 on a 9-point Likert scale by the doctor, and by changes that could be attributed to the homeopathic medicine. Association between scores for change of main complaint and scores for 'best homeopathic case' was analysed by the Kruskal gamma test. RESULTS: Three-hundred and ninety-nine patients were included. In 49.1%, the main complaint was present for >= 2 years. The most common diagnosis was 'fatigue' (N = 56; 14%). Major improvement in the main complaint (score +3) was reported by 22 to 26% at consecutive follow-up visits. One-hundred and ninety-six patients were treated with a single homeopathic medicine, among whom 66 'best homeopathic cases' were identified. The correlation between patient-reported changes of main complaint and assessment by the doctor was significant (gamma = 0.832; p < 0.001). CONCLUSIONS: Registration of (co )diagnoses, chronicity, treatments and outcomes in homeopathic practice with identification of 'best homeopathic cases' is feasible, using the tools provided. A user-friendly electronic database for efficient recording is recommended. PMID- 30290380 TI - ? PMID- 30290379 TI - Bilateral Globus Pallidus Internus Deep Brain Stimulation in a Case of Progressive Dystonia in Mohr-Tranebjaerg Syndrome with Bilateral Cochlear Implants. AB - INTRODUCTION: A 28-year-old man presented with a history of sensorineural deafness since early childhood treated with bilateral cochlear implants (CIs). He showed signs of debilitating dystonia that had been present since puberty. Dystonic symptoms, especially a protrusion of the tongue and bilateral hand tremor, had not responded to botulinum toxin therapy. We diagnosed Mohr Tranebjaerg syndrome (MTS). METHODS AND MATERIAL: Deep brain stimulation (DBS) of the bilateral globus pallidus internus was performed predominantly with stereotaxic computed tomography angiography guidance under general anesthesia. Electrophysiology was used to identify the target regions and to guide DBS electrode placement. RESULTS: In the immediate postoperative course and stimulation, the patient showed marked improvement of facial, extremity, and cervical dystonia. More than 2 years after implantation, his dystonic symptoms had dramatically improved by 82%. DISCUSSION: MTS is a rare genetic disorder leading to sensorineural deafness, dystonia, and other symptoms. The use of DBS for the dystonia in MTS was previously described but not in the presence of bilateral CIs. CONCLUSION: DBS in MTS may be a viable option to treat debilitating dystonic symptoms. We describe successful DBS surgery, despite the presence of bilateral CIs, and stimulation therapy over 2 years. PMID- 30290381 TI - ? PMID- 30290382 TI - ? PMID- 30290383 TI - ?

Injuries occur on the basis of degeneration or acute trauma. The understanding of anatomy and biomechanical function plays an essential role for choosing the right diagnostic methods and initiating successful treatment. Besides clinical examination ultrasound is a cost efficient primary diagnostic measure. Additional MRI can be beneficial for partial tears or chronic ruptures. Non-operative treatment is suitable for minor partial ruptures with sustained function. The most common methods for reattachment of the quadriceps and patellar tendon are either sutures placed through transpatellar drill holes or the use of suture anchors. For chronic ruptures various methods have been shown to be well accomplished. Most commonly local tendon flaps or harvested tendon transplants have shown good clinical outcomes. Early primary repair leads to mainly good functional outcomes. The results of chronic disruptions of the extensor mechanism of the knee vary widely. PMID- 30290394 TI - Effects of Repeated Bouts of Exercise on the Hemostatic System. AB - Physical activity is beneficial for health, for example, by lowering the risk of cardiovascular events. However, vigorous exercise is associated with the occurrence of thromboembolic events and sudden cardiac death, in particular in untrained individuals. Whereas acute exercise is known to cause a hypercoagulable state, repeated exposure to (strenuous) exercise by means of training may actually condition the hemostatic response to exercise. To date, the effects of exercise training on blood coagulability and the underlying mechanisms have yet to be fully discerned. In this review, the authors provide an overview of existing literature on how training programs and training status influence hemostasis in healthy individuals. Furthermore, they present data of a pilot study in which we studied the effects of repetitive submaximal intensity cycling on procoagulant and anticoagulant processes. It is known that factor VIII (FVIII) and von Willebrand factor (VWF) increase after exercise, but we found that this increase in FVIII and VWF (antigen, propeptide, and VWF in active conformation) was smaller on each of three subsequent days, suggesting either adaptation of endothelial activation or exhaustion of endothelial VWF supplies. With respect to thrombin generation, elevated FVIII significantly increased the thrombin generation peak but not the endogenous thrombin potential. In contrast, platelet activation in terms of P-selectin expression after stimulation with protease activated receptor-1 and glycoprotein VI agonists decreased after exercise and did not recover, indicating exhaustion of the platelet response to repetitive exercise.

Due to an overall increase in case numbers, the number of MDK examinations leading to the assessment of primary incorrect occupancy is also increasing. This results in a multitude of social court disputes in which medical assessments are required. With knowledge of the legal norms and relevant guidelines or other recommendations, the expert can take this topic step by step. The starting point here is the evaluation of the patient file, followed by the examination of the medical indication, the implementation of the therapy and, finally, the answers to the questions of proof. A test scheme based on the Schroter concept can further simplify this process. PMID- 30290396 TI - Infraspecific Variation of Huperzine A and B in Icelandic Huperzia selago Complex. AB - The alkaloids huperzine A and huperzine B were originally isolated from the Chinese club moss Huperzia serrata. They are known inhibitors of acetylcholinesterase, and especially huperzine A shows pharmaceutical potential for the treatment of Alzheimer's disease. Its supply heavily relies on natural plant sources belonging to the genus Huperzia, which shows considerable interspecific huperzine A variations. Furthermore, taxonomic controversy remains in this genus, particularly in the Huperzia selago group. With focus on Icelandic H. selago taxa, we aimed to explore the relatedness of Huperzia species using multi-locus phylogenetic analysis, and to investigate correlations between huperzine A contents, morphotypes, and genotypes. Phylogenetic analysis was performed with five chloroplastic loci (the intergenic spacer between the photosystem II protein D1 gene and the tRNA-His gene, maturase K, ribulose-1,5 bisphosphate carboxylase/oxygenase large subunit, tRNA-Leu, and the intergenic spacer region between tRNA-Leu and tRNA-Phe). Huperzine A and huperzine B contents were determined using an HPLC-UV method. The phylogenetic analysis suggests that previously proposed Huperzia appressa and Huperzia arctica should not be considered species, but rather subspecies of H. selago. Three genotypes of Icelandic H. selago were identified and presented in a haplotype networking diagram. A significantly (p < 0.05) higher amount of huperzine A was found in H. selago genotype 3 (264 - 679 ug/g) than genotype 1 (20 - 180 ug/g), where the former shows a typical green and reflexed "selago" morphotype. The huperzine A content in genotype 3 is comparable to Chinese H. serrata and a good alternative huperzine A source. Genotype 2 contains multiple morphotypes with a broad huperzine A content (113 - 599 ug/g). The content of huperzine B in Icelandic taxa (6 - 13 ug/g) is much lower than that in Chinese H. serrata (79 - 207 ug/g).

AB - Previous research has evaluated public risk perception and response to a natural hazards in various settings; however, most of these studies were conducted either with a single scenario or after a natural disaster struck. To better understand the dynamic relationships among affect, risk perception, and behavioral intentions related to natural disasters, the current study implements a simulation scenario with escalating weather intensity, and includes a natural experiment allowing comparison of public response before and after a severe tornado event with extensive coverage by the national media. The current study also manipulated the display of warning information, and investigated whether the warning system display format influences public response. Results indicate that (1) affect, risk perception, and behavioral intention escalated as weather conditions deteriorated, (2) responses at previous stages predicted responses at subsequent stages of storm progression, and (3) negative affect predicted risk perception. Moreover, risk perception and behavioral intention were heightened after exposure to the media coverage of an actual tornado disaster. However, the display format manipulation did not influence behavioral responses. The current study provides insight regarding public perception of predisaster warnings and the influence of exposure to media coverage of an actual disaster event. PMID- 30290398 TI - Comparison of Decision Tree and Logistic Regression Models for Utilization in Sexual Assault Kit Processing. AB - To combat the influx of sexual assault kits (SAKs) that need to be tested, an exploration of data from Ohio's SAK Testing Initiative was carried out to identify variables that impact whether a SAK contains a probative DNA profile that is eligible for the Combined DNA Index System (CODIS) database. A validation study was completed to confirm the existence of variable relationships from the initial examination of data; new and modified statistical models were introduced to improve the predictive accuracy to determine if a SAK will contain at least one CODIS eligible DNA profile. Descriptive statistics from the validation data set confirmed conclusions about the effects of days between the assault and kit collection, the age of the victim, and consensual sex around the time of the kit collection for obtaining CODIS eligibility of DNA. The decision tree was selected as the best model. PMID- 30290399 TI - Innervation of the Epithelium and Lamina Propria of the Urethra of the Female Rat. AB - The aim of this study was to characterize the number, type and distribution of immunochemically identified nerves in epithelium and lamina propria of the female rat urethra. Urethras from female Sprague-Dawley rats (n = 12) were fixed, frozen and sectioned (8 MUm). Standard immunohistochemical techniques were used to identify putative nerves using the following antibodies: calcitonin gene related peptide (cgrp), neuronal nitric oxide synthase (nNos), tyrosine hydroxylase (TH) and vesicular acetylcholine transporter (vacht). The number, distribution and characteristics of all immunoreactive (IR) structures adjacent to the urethral epithelium and in the lamina propria was assessed. In the bladder, few cgrp-IR and vacht-IR fibers were associated with the urothelium or suburothelium of the lateral wall. In contrast, large numbers of vacht-IR, nNos-IR and cgrp-IR fibers were found close to the epithelium and subepithelium of the bladder neck and throughout the urethra. The number of cgrp-IR fibers was significantly higher in the urethra in comparison with the bladder neck. A population of undescribed cgrp IR cells associated with the bladder neck and proximal urethra has been characterized. Each of these cells appears to be associated with a nerve fiber. In the distal urethra, the number of peptidergic fibers penetrating the epithelium was significantly higher than the rest of the urethra. Clearly, this study has revealed a highly complex and heterogeneous network of putative afferent nerves fibers along the length of the urethra. These structural specializations need to be taken into account when probing the different functions of the urethra. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30290400 TI - MiR-141-3p Suppresses Tumor Growth and Metastasis in Papillary Thyroid Cancer via Targeting Yin Yang 1. AB - MicroR-141-3p has been found to be downregulated in papillary thyroid carcinoma (PTC), while little is known about the cellular functions and precise signals elicited by miR-141-3p in PTC. The results of this study indicated that the expression of miR-141-3p was aberrantly down-regulated in PTC tissues and cell lines, compared with the adjacent normal tissues and normal thyroid epithelial cells. Furthermore, the miR-141-3p expression level was negatively associated with TNM stage and lymph node metastasis in PTC. Expression of miR-141-3p effectively inhibited cell growth, promoted apoptosis, and suppressed invasion in PTC cells. Meanwhile, miR-141-3p knockdown with miR-141-3p inhibitor reversed these effects. Consistent with the in vitro study, miR-141-3p also exhibited anti neoplastic activity in vivo. Moreover, the results revealed that miR-141-3p directly recognized the 3' untranslated region (3'UTR) of Yin Yang 1 (YY1) and negatively regulated the expression of YY1 at both protein and mRNA levels. Ectopic expression of YY1 could effectively abrogate the anti-metastatic and proapoptotic effects of miR-141-3p. In summary, the findings suggested that miR 141-3p can act as a tumor suppressor in PTC and may be a potential therapeutic target for PTC treatment. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc.

PMID- 30290401 TI - The changes of mitochondria in substantia nigra and anterior cerebral cortex of hepatic encephalopathy induced by thioacetamide. AB - Hepatic encephalopathy (HE) is a neuropsychiatric syndrome resulting from chronic or acute liver failure. Under the condition of hepatic encephalopathy, various factors such as reactive oxygen species (ROS), inflammatory factors, ammonia poisoning and amino acids alteration lead to changes of mitochondria. Selective depletion of damaged mitochondrion is essential for maintaining the morphology and function of mitochondria and cells. In this study, molecular biology analysis was used to analyze the mitochondrial morphology in the substantia nigra (SN) and anterior cerebral cortex (ACC) of the HE mice. The results revealed that the drp1, mfn1 and mfn2 increased in mRNA level of SN, which indicated the changes of mitochondrial morphology in HE mice. The drp1 and mfn2 genes were up-regulated, then, the Opa1 exhibited no significant change in the ACC of HE mice. Further study demonstrated that the mitochondrial autophagy related genes, pink1 and parkin, increased in SN, while the parkin reduced in ACC of HE mice. In addition, uncoupling protein (ucp2) increased in mRNA level of SN and ACC, and the ucp4 had no change or reduced in SN and ACC, respectively. These findings suggested that the mitochondrial dynamics is different in the substantia nigra and anterior cerebral cortex of hepatic encephalopathy mice. Therefore, our results indicated that mitochondrial dynamics provided a potential treatment strategy for hepatic encephalopathy through the fission, fusion and autophagy of genes.

AB - Trans-sphenoidal surgery, which is the most widely used technique for the treatment of pituitary tumors, has continued to evolve by introducing new approaches and technologies, such as the direct endonasal route and the endoscope. The endonasal approach is a minimally invasive route to the sella turcica with the advantages of using a simpler and more rapid nasal dissection and eliminating the nasal and lip complications. Restricted exposure provided by the endonasal approach is overcome by combined use of an endoscope that provides a more panoramic view of the surgical field beyond the area covered by the operating microscope. An operating microscope permits binocular vision and bimanual technique, which are familiar to neurosurgeons. Neurosurgeons should exploit the advantages of both modalities for the benefit of patients. This review describes the advances in trans-sphenoidal surgery focusing on the endoscopic approach. PMID- 30290407 TI - Approaches to dyslipidemia treatment in children and adolescents. AB - Atherosclerosis represents a disease that begins in childhood, and alterations in lipid concentration play a fundamental role in the development of this condition. Children and adolescents with high cholesterol levels are more likely than their peers in the general population to present with dyslipidemia in adulthood. Precocious identification of dyslipidemias associated with premature cardiovascular disease is crucial during childhood to delay or prevent the atherosclerotic process. The National Cholesterol Education Program has established guidelines for the diagnosis and treatment of dyslipidemia during pediatric age. It has been suggested that a heart-healthy diet should begin at 2 years of age, and no adverse effects on psychological aspects, growth, pubertal development and nutritional status in children and adolescents limiting total and saturated fat intake have been demonstrated. Pharmacotherapy should be considered in children aged 10 years or older when low-density lipoprotein cholesterol concentrations remain very high despite dietary therapy, especially when multiple risk factors are present. The lipid-lowering drugs recommended for childhood and adolescence are resins and statins. The increasing use of statins is dependent on their effectiveness and safety. Ezetimibe, a selective cholesterol absorption inhibitor, may provide a similar cholesterol-lowering effect as that reached with statin treatment. This review provides an update on recent advances in the therapy of dyslipidemia, especially hypercholesterolemia, during pediatric age and adolescence. PMID- 30290408 TI - Pendred syndrome. AB - Pendred syndrome (PDS) is an autosomal recessive disorder clinically characterized by sensorineural hearing loss and goiter. PDS is mainly caused by mutations in the SLC26A4 gene, although a few cases are due to mutations in the FOXI1 gene. SLC26A4 encodes pendrin, a sodium-independent transporter of iodide/chloride, chloride/formate and bicarbonate, that is expressed in the inner ear, thyroid gland, syncytiotrophoblast cells, endometrium and kidney. FOXI1 encodes a transcription factor necessary for pendrin expression. Patients with PDS show a bilateral and severe-to-profound hearing loss, although some cases present with a slowly progressive and fluctuating course. Temporal bone abnormalities with enlargement of the vestibular aqueduct, alone or with Mondini dysplasia, are common. Goiter appears most frequently in the second decade of life with a range of variations in size, depending on the amount of iodide intake and the effect that the mutation causes in pendrin function in any individual patient. A standard thyroid hormone-replacement regimen should be given to PDS patients with hypothyroidism to re-establish euthyroidism and prevent or decrease goiter growth. Total or partial thyroidectomy is occasionally the treatment of choice. Hearing aids and proper educational programs should also be offered to patients. PMID- 30290409 TI - Role of calcium metabolism in premenstrual syndrome. AB - Premenstrual syndrome has been the subject of many myths and misconceptions over the centuries. It is a very common problem affecting millions of young women during their reproductive lives and is characterized by numerous recurrent, cyclical emotional and physical symptoms during the luteal phase of the menstrual cycle. The etiology of this disorder has remained poorly understood until only recently. Alterations in calcium homeostasis have long been associated with many affective disorders. Cyclical fluctuations of the ovarian steroid hormones across the menstrual cycle influence calcium metabolism, affect intestinal calcium absorption and modulate 1,25-dihydroxyvitamin D synthesis. Evidence now strongly suggests that abnormalities in calcium and vitamin D metabolism, specifically calcium and vitamin D deficiency, are responsible for these luteal-phase symptoms. Calcium and vitamin D supplementation may offer a simple solution to millions of women affected with premenstrual syndrome. PMID- 30290410 TI - Imaging of hyperfunctioning adrenal masses. AB - Adrenal imaging not only aims to detect hyperfunctioning adrenal lesions responsible for distinct clinical syndromes (pheochromocytoma, Cushing's syndrome or primary aldosteronism) but also to differentiate malignant from benign disease. Computed tomography (CT), MRI and high-resolution ultrasound imaging methods are available for detection of adrenal masses with high sensitivities. Although the risk of malignancy increases with the size of the adrenal mass, this criterion does not discriminate malignant from benign disease with sufficient specificity. Attenuation values on unenhanced CT, contrast washout characteristics on CT and chemical-shift imaging on MRI help differentiate adrenal adenomas and nonadenomas. Adrenal lesions with equivocal results on CT and MRI can be characterized further by functional nuclear medicine imaging. Radiopharmaceutical agents specifically detect masses derived from the adrenal cortex (e.g.,131I-6-iodomethyl-norcholesterol) and from the adrenal medulla (e.g., 123I- and 131I-meta-iodobenzylguanidine). Unspecific tracers, such as 18F fluorodeoxyglucose, are very useful in discriminating malignant and benign adrenal tumors. PMID- 30290411 TI - Human PAF complexes in endocrine tumors and pancreatic cancer. AB - The human RNA polymerase II-associated factor (hPAF) complex is comprised of five subunits that include hPaf1, parafibromin, hLeo1, hCtr9 and hSki8. This multifaceted complex was first identified in yeast (yPAF) and subsequently in Drosophila and humans. Recent advances in the study on hPAF have revealed various functions of the complex in humans that are similar to yPAF, including efficient transcription elongation, mRNA quality control and cell cycle regulation. A major component of the hPAF complex, hPaf1, is amplified and overexpressed in pancreatic cancer. The parafibromin subunit of the hPAF complex is a product of the hereditary hyperparathyroidism type 2 (HRPT-2) tumor-suppressor gene, which is mutated in the germ line of hyperparathyroidism-jaw tumor patients. This review evaluates the role of the hPAF complex and its individual subunits in endocrine and pancreatic cancers. It focuses on the functions of the hPAF complex and its individual subunits and dysregulation of the complex, thus providing an insight into its potential involvement in the development of endocrine cancers and other tumor types. PMID- 30290412 TI - Sphingomyelin synthases and testicular function. AB - Sphingomyelin synthase (SMS) is a cellular enzyme that catalyzes de novo synthesis of sphingomyelin (SM), which is a vital lipid component of cell membranes. Both members of the SMS family, SMS1 and SMS2, are found in mammalian testes and they are located in distinctive subcellular compartments, with SMS1 in the Golgi apparatus and SMS2 in the plasma membrane. At present, the precise function of SMS in the testis remains unknown. Recent studies have demonstrated an unique association of SMS2 with spermatids, particularly near developing acrosomes and the junction restructuring site at the apical ectoplasmic specialization (a testis-specific atypical adherens junction type) and Leydig cells in the rat testis. These data illustrate the possible involvement of SMS2 in spermiogenesis and, perhaps, steroidogenesis in male reproductive function. This review summarizes the latest findings on SMS in the field, particularly its role in testicular function. PMID- 30290413 TI - Hypothalamic regulation of appetite. AB - The prevalence of obesity is steadily rising and has huge health and financial implications for society. Weight gain is due to an imbalance between dietary intake and energy expenditure and research has focused on trying to understand the complex pathways involved in controlling these aspects. This review highlights the key areas of research in the hypothalamic control of appetite. The hypothalamus consists of several nuclei that integrate peripheral signals, such as adiposity and caloric intake, to regulate important pathways within the CNS controlling food intake. The best characterized pathways are the orexigenic neuropeptide Y/Agouti-related protein and the anorexigenic pro opiomelanocortin/cocaine- and amphetamine-related transcript neurons in the arcuate nucleus of the hypothalamus. These project from the arcuate nucleus to other key hypothalamic nuclei, such as the paraventricular, dorsomedial, ventromedial and lateral hypothalamic nuclei. There are also projections to and from the brainstem, cortical areas and reward pathways, all of which influence food intake. The challenge at present is to understand the complexity of these pathways and try to find ways of modulating them in order to find potential therapeutic targets. PMID- 30290415 TI - Anti-estrogen therapy offers new hope for ovarian cancer patients. PMID- 30290414 TI - Identification, treatment and management of cardiovascular risks in patients with acromegaly. AB - Acromegaly, a syndrome related to growth hormone/IGF-1 excess, is frequently complicated by cardiovascular abnormalities (acromegalic cardiomyopathy). Extremely frequent are left ventricular hypertrophy and alterations of diastolic filling, which may progress to systolic dysfunction and eventually heart failure. Cardiac abnormalities may normalize after successful medical or surgical treatment of acromegaly, particularly in young patients with short-lasting disease, but this is less likely to occur in elderly patients. Both hypertension and cardiac valve disease are frequently encountered in acromegaly, but neither seems to be favorably influenced by disease control. The prevalence of coronary heart disease (CHD) is controversial but is probably not increased in acromegaly. Arrhythmias are relatively common in untreated acromegalic patients, although their clinical relevance is unknown. A cardiac evaluation of acromegalic patients should include echocardiography, basal electrocardiogram and blood pressure measurement, and evaluation of common risk factors for CHD. Appropriate and prompt treatment allowing a rapid control of growth hormone/IGF-1 hypersecretion is warranted because many features of acromegalic cardiomyopathy may be reverted, particularly in younger patients. In view of the lack of association with acromegaly, common risk factors for CHD, hypertension, arrhythmias or valve disease should be managed independently, irrespective of control of disease activity.

AB - Type 2 diabetes mellitus and chronic kidney disease in mild and moderate stages is a common and underestimated comorbidity with relevant therapeutic consequences. Available oral antidiabetic agents are effectively used in keeping blood glucose levels within the guideline range but long lists of contraindications often limit their use. Chronic kidney disease is a very common reason to withhold or discontinue an oral antidiabetic therapy, precluding many patients from drugs with proven benefit, such as metformin. Often contraindications are not based on data but on theoretical grounds or expert opinion. In this review, we critically review threshold levels of kidney function for common oral antidiabetic agents, the evidence from which they were derived and offer advice on how to monitor kidney function as an important procedure in clinical practice. PMID- 30290418 TI - Noncoding miRNAs as key controllers of pancreatic beta-cell functions. AB - miRNAs, a recently discovered family of small noncoding RNAs, are emerging as major controllers of gene expression and key determinants of pancreatic beta-cell function. These 19-22-nucleotide molecules govern gene expression by partially pairing to 3'-untranslated regions of target mRNAs and by inhibiting their translation. The elucidation of the role of miRNAs promises to unravel new aspects of beta-cell biology and to clarify the mechanisms leading to defective insulin secretion in diabetes mellitus. This information is expected to favor the design of new approaches for preserving functional beta-cells in prediabetic stages and the development of strategies for engineering insulin-secreting cells capable of replacing endogenous beta-cells in diabetic patients. PMID- 30290419 TI - Role of radiolabeled octreotide therapy in patients with metastatic neuroendocrine neoplasms. AB - Peptide receptor radionuclide therapy is a new therapeutic modality for patients with nonresectable neuroendocrine tumors. The technique is based on the unique ability of these tumors to express cell membrane-specific peptide receptors that can be targeted with radiolabeled somatostatin analogues. A high level of uptake on somatostatin receptor scintigraphy is a prerequisite for effective treatment. The efficacy of this method has been proven in several clinical trials. In a substantial number of patients, an improvement of life quality has been achieved in addition to a marked morphologic and biochemical tumor response. Serious side effects are rarely observed. Attention must be paid to kidney protection during the treatment. The present review summarizes the clinical experience with the treatment of advanced neuroendocrine tumors with radiolabeled somatostatin analogues and focuses on patient selection and the appropriate timing of the therapy. Finally, it emphasizes treatment-related issues that deserve attention in the future. PMID- 30290420 TI - Challenges in studies of the genetic basis of Type 2 diabetes. AB - The prevalence of diabetes is increasing worldwide in epidemic proportions. This increase is mainly due to increased incidence and prevalence of Type 2 diabetes, which accounts for 80-90% of all cases of diabetes. The susceptibility to develop Type 2 diabetes is determined by genetic and environmental factors. Major genes responsible for Type 2 diabetes have not yet been identified. The most replicated susceptibility gene for Type 2 diabetes is TCF7L2, recently published by investigators from Iceland. The second most widely replicated association between a genetic variation and the risk of Type 2 diabetes is that of the Pro12Ala polymorphism in the peroxisome proliferator-activated receptor gamma2 gene. Furthermore, the common E23K polymorphism in the KCJN11 gene, encoding the ATP sensitive potassium-channel subunit Kir6.2, and variants in the calpain-10 gene have been associated with increased susceptibility to Type 2 diabetes in meta analyses. Several studies have investigated the possibility that rare, highly penetrant mutations in the maturity-onset diabetes of the young genes lead to monogenic diabetes, while common polymorphisms increase the susceptibility to Type 2 diabetes. Indeed, there is increasing evidence that single nucleotide polymorphisms in hepatic nuclear factor-4alpha are significantly associated with the risk of Type 2 diabetes. In this review, different approaches to identify susceptibility genes for Type 2 diabetes are discussed. In particular, the importance of prospective population-based cohort studies and prospective intervention studies are emphasized. Finally, genome-wide association studies using single nucleotide polymorphisms randomly spaced across the entire genome may be useful in the identification of susceptibility genes for Type 2 diabetes. PMID- 30290421 TI - AIP gene in pituitary adenoma predisposition. AB - Germline mutations in the aryl hydrocarbon receptor interacting protein (AIP) gene were recently shown to cause susceptibility to pituitary adenoma predisposition. The purpose of this review is to briefly recapitulate the current knowledge on hereditary susceptibility to pituitary adenomas and what led to the identification of AIP as a novel predisposition gene. We will then concentrate on the data on AIP mutations and pituitary adenoma predisposition phenotype that have accumulated since the gene was identified. Major future challenges, as well as the possibilities for clinical practice based on this recent finding, will also be discussed. PMID- 30290422 TI - Renal hemodynamics in overweight and obesity: pathogenetic factors and targets for intervention. AB - Weight excess is a risk factor for progressive renal function loss, not only in subjects with renal disease or renal transplant recipients, but also in the general population. Considering the increasing prevalence of obesity worldwide, weight excess may become the main renal risk factor on a population basis, all the more so because the risk is not limited to morbid obesity, but is already apparent in the overweight range. The mechanism of the renal risk is multifactorial. In addition to the role of comorbid conditions such as hypertension and diabetes, current evidence supports a pathogenetic role for renal hemodynamics, specifically glomerular hyperfiltration, and also glomerular hypertension. Weight excess is associated with an elevated glomerular filtration rate and a less pronounced rise in renal plasma flow, resulting in an elevated filtration fraction. This suggests glomerular hypertension due to afferent efferent dysbalance, which impairs glomerular protection from systemic hypertension. Data in renal transplant recipients support the pathogenetic role of elevated glomerular pressure for long-term renal prognosis. Blockade of the renin-angiotensin-aldosterone system can reverse the renal hemodynamic abnormalities. The obesity-associated renal risk is unfavourably affected by high sodium intake. This may be due to the effects of sodium on blood pressure, which is often sodium-sensitive in obesity, but direct renal effects are also present. Interestingly, sodium restriction ameliorates overweight-associated hyperfiltration in overweight subjects. More focus on weight excess as a renal risk factor is warranted. Preventive measures should focus on weight excess as well as on specific protection against renal damage, by renin-angiotensin aldosterone system-blockade and moderate sodium restriction. PMID- 30290423 TI - Function of nuclear steroid receptors in apoptosis: role of ursodeoxycholic acid. AB - Nuclear steroid receptors such as the glucocorticoid and the mineralocorticoid receptors modulate apoptosis in different cell types through transactivation dependent and -independent mechanisms. They are involved in both the induction and prevention of apoptosis depending on cell type. However, it is unclear how nuclear steroid receptors can affect expression of the same gene in opposing ways for different cells. In addition to their function as modulators of gene expression, nuclear steroid receptors often act as nuclear transporters of other regulatory molecules, thus indirectly regulating several apoptosis-related genes. Curiously, nuclear steroid receptors are thought to cooperate with the antiapoptotic endogenous bile acid, ursodeoxycholic acid, to prevent programmed cell death. The next decade will almost certainly unveil the remarkable role of nuclear steroid receptors in modulating the life and death struggle of cells and organ systems in human development and function. PMID- 30290424 TI - Genetics and pharmacogenetics of estrogen response. AB - Estrogens are a steroid hormone group distributed widely in animals and human beings. Estrogens diffuse across cell phospholipidic membranes and interact with estrogen receptors. Their highest concentration is found in target tissues with reproductive function (breast, ovary, vagina and uterus). High estrogen levels are usually associated with tumor onset and progression, while loss of estrogen or its receptor(s) contributes to development and/or progression of various diseases (osteoporosis, neurodegenerative disease and cardiovascular disease). Despite the numerous efforts to highlight estrogen's mechanism of action, recent discoveries showed an unexpected degree of complexity of estrogenic response. PMID- 30290425 TI - Breathing disorders in Prader-Willi syndrome: the role of obesity, growth hormone treatment and upper respiratory tract infections. AB - Prader-Willi syndrome is a neurogenetic disorder characterized by a number of signs and symptoms, including muscular hypotonia in infancy, hypogonadism, obesity and short stature. Neurobehavioral abnormalities and cognitive impairment are common. In addition, breathing abnormalities have been described, including sleep-related breathing disorders, abnormal chemoreceptor sensitivity and pulmonary function abnormalities. Growth hormone treatment is now widely used in children with Prader-Willi syndrome to improve growth and body composition. Over the last 4 years, case reports have been published concerning unexpected death, many of which were related to respiratory abnormalities. This review focuses on breathing abnormalities in Prader-Willi syndrome individuals and the influence of obesity, growth hormone treatment and upper respiratory tract infections. PMID- 30290426 TI - The role of lanreotide Autogel(r) in the treatment of acromegaly. AB - Acromegaly is a rare disease, but all clinicians have to be aware of the diagnosis in order to minimize the negative consequences of increased levels of growth hormone and IGF-I, and the possible impact of a pituitary macroadenoma. Surgery remains the first-line therapy and may alleviate both hormonal excess and symptoms due to tumor mass effects. Postoperatively, however, many patients may need adjunctive therapy. Somatostatin analogs were marketed for clinical use in the 1980s. The depot formulations of the synthetic somatostatin analogs octreotide and lanreotide, octreotide acetate long-acting repeatable and lanreotide sustained release, were developed by incorporating the analogs into microspheres. The advantage of the new formulation of lanreotide, lanreotide Autogel(r), is the prefilled syringe of lanreotide and water. The choice of analog should be individualized for each patient based on level of efficacy, adverse event profile and preferred mode of administration. Approximately a third of acromegalic patients are resistant to the currently available somatostatin analogs. Monotherapy using cabergoline or pegvisomant is clinically available. Adding cabergoline to a somatostatin analog may be advantageous in selected patients and promising data exist regarding combination therapy with pegvisomant. Radiotherapy is still an option; however, although treating comorbidities and avoiding hypopituitarism is very important, radiotherapy should only be used for selected patients where treatment targets cannot be achieved by using the other therapies. PMID- 30290427 TI - Skeletal muscle AMP kinase as a target to prevent pathogenesis of Type 2 diabetes. AB - The metabolic property of skeletal muscle is highly malleable and adapts to various physiological demands by shifting energy-substrate metabolism. Skeletal muscle metabolism has a significant impact on whole-body metabolism and substrate utilization. Glucose and lipids are the main oxidative fuel substrates in skeletal muscle, and their utilization is coordinated by complex regulatory mechanisms. In people with Type 2 diabetes, glucose uptake and lipid oxidation in skeletal muscle are impaired. These metabolic defects are coupled to impaired insulin signaling. Exercise increases glucose uptake and lipid oxidation by an insulin-independent mechanism. The AMP-activated protein kinase (AMPK) cascade is activated in response to metabolic stress and has therefore been implicated in the regulation of exercise-induced metabolic and gene regulatory responses. AMPK is a heterotrimeric complex composed of a catalytic alpha, and regulatory beta and gamma subunits. Selective regulation of AMPK in skeletal muscle may be achieved by targeting alpha1/beta2/gamma3 heterotrimeric complexes. Activation of AMPK enhances GLUT4 translocation of glucose uptake in skeletal muscle from Type 2 diabetic patients and animal models of the disease by an insulin-independent mechanism. Transgenic overexpression of mutated forms of the AMPK gamma3 subunit provide evidence that activation of AMPK promotes lipid oxidation and prevents the development of skeletal muscle insulin resistance. Thus, AMPK provides a molecular entry point into novel regulatory pathways to enhance lipid and glucose metabolism in an effort to prevent and treat skeletal muscle insulin resistance associated with Type 2 diabetes.

AB - Hepatocyte nuclear factor (HNF)-1alpha and HNF-1beta are transcription factors that regulate many target genes in various tissues including liver, pancreas and kidney. Heterozygous mutations in the HNF-1alpha and HNF-1beta genes result in maturity-onset diabetes of the young (MODY)3 and MODY5, respectively. The discovery of these 'hepatocyte nuclear factors' as MODY-responsible genes provided a breakthrough in the field of diabetes. Patients with HNF-1alpha and HNF-1beta mutations, as well as their model mice, show impaired pancreatic beta cell function. The mechanism of impaired beta-cell function and the target genes has been intensively investigated by considerable in vitro and in vivo studies. The insulin gene is one of the target genes of HNF-1alpha and HNF-1beta in the beta-cells, and may contribute to the diabetes. The IGF-1 gene is also regulated by HNF-1alpha and HNF-1beta, and its decreased expression may contribute to growth failure and impaired beta-cell proliferation. Mutations in HNF-1beta result in symptoms in multiple organs, including kidney and liver, and several target genes have been reported to be involved in the pathogenesis. HNF-1alpha and HNF-1beta may be one of the master regulators of hepatocyte and islet transcription, and further investigations by microarray and genome-scale analyses are providing information for the better understanding of the complex transcriptional network involving HNF-1alpha and -1beta. PMID- 30290433 TI - Phosphatonins: new hormones that control phosphorus homeostasis. AB - Phosphorus (Pi) plays an important role in nucleic acid synthesis, energy metabolism, bone mineralization and cell signaling, and is also present in sugars, phospholipids and phosphoproteins. Phosphate homeostasis is controlled by processes that regulate the intestinal absorption and renal excretion of Pi, and bone turnover. These processes are influenced by peptide and sterol hormones, such as parathyroid hormone and 1alpha,25-dihydroxyvitamin D (1alpha,25[OH]2D3). Recently, a new class of phosphate-regulating peptides has been discovered: phosphatonins. These factors, such as FGF-23, secreted frizzled-related protein 4, matrix extracellular phosphoglycoprotein and FGF-7, are circulating peptides with potent phosphaturic activity. These peptides inhibit Na/Pi transporters in renal epithelial cells and, therefore, increase renal Pi excretion. In addition, FGF-23 and secreted frizzled-related protein-4 inhibit 25-hydroxyvitamin D 1alpha hydroxylase activity, reducing 1alpha,25(OH)2D3 synthesis and, thus, intestinal Pi absorption. Phosphatonins have been associated with hypophosphatemic diseases, such as tumor-induced osteomalacia, X-linked hypophosphatemic rickets, autosomal dominant hypophosphatemic rickets, autosomal recessive hypophosphatemic rickets and hyperphosphatemic disease (e.g., tumoral calcinosis). The aim of this article is to review the role of phosphatonins in Pi metabolism in normal and pathologic conditions and also to investigate the correlations among the various phosphatonins. PMID- 30290434 TI - Detection of medullary thyroid cancer: a focus on serum calcitonin levels. AB - Medullary thyroid cancer (MTC) is a neuroendocrine tumor derived from the C cells of the thyroid. C cells are responsible for the production of calcitonin, a sensitive and specific marker for MTC. Early detection of MTC is essential; overall survival from MTC is related to patient age, stage of disease and extent of surgical resection. Elevated preoperative serum calcitonin levels have been shown to predict the likelihood of biochemical remission postoperatively. The use of routine serum calcitonin measurements as a screening measure for MTC in patients with thyroid nodules has been advocated in Europe. To date, routine calcitonin measurement has not been widely practiced in the USA; a recent cost effectiveness analysis suggests routine serum calcitonin measurements in patients with thyroid nodules may be comparable to other widely accepted screening programs. PMID- 30290435 TI - Hypothyroxinemia of prematurity: cause, diagnosis and management. AB - Infants born at extreme prematurity are at a high risk of developmental disability. A major risk factor for disability is having a low level of thyroid hormone, described as hypothyroxinemia, which is recognized to be a frequent phenomenon in these infants. At present, there is uncertainty among clinicians regarding the most appropriate method of managing hypothyroxinemia of prematurity. The literature suggests that some, but not all, forms of thyroid supplementation may reduce the incidence of disability in infants born at extreme prematurity. There is a pressing need to confirm the benefit of treatment and to establish the optimal way to treat transient hypothyroxinemia in these infants. PMID- 30290436 TI - Thyroid-stimulating hormone/cAMP-mediated proliferation in thyrocytes. AB - Current research on thyrotropin-activated proliferation in the thyrocyte needs to be aimed at a better understanding of crosstalk and negative-feedback mechanisms with other proliferative pathways, especially the insulin/IGF-1-induced phosphoinositol-3 kinase pathway and the serum-induced MAPK or Wnt pathways. Convergence of proliferative pathways in mTOR is a hotspot of current research, and combined treatment using double class inhibitors for thyroid cancer may bring some success. New thyroid-stimulating hormone receptor (TSHR)-interacting proteins, a better picture of cAMP targets, a deeper knowledge of the action of the protein kinase A regulatory subunits, especially their interactions with the replication machinery, and a further understanding of mechanisms that lead to cell cycle progression through G1/S and G2/M checkpoints are areas that need further elucidation. Finally, massive information coming from microarray data analysis will prompt our understanding of thyroid-stimulating hormone-promoted thyrocyte proliferation in health and disease. PMID- 30290437 TI - Control of colon cancer development and progression by selected estrogen receptor modulators. AB - Estrogens behave as protective agents on the development of colorectal cancer, and hormonal-replacement therapy is associated with an increased survival rate in women with this disease, indicating that estrogenic therapy correlates with a better prognosis. The protective effect of estrogens on Fcolorectal cancer development and progression is presumably related to the expression of estrogen receptors in colon mucosa, with the estrogen receptor-beta isoform being the predominant one. This observation suggests that estrogen receptor-beta could have an inhibitory effect on colorectal cancer cell proliferation and a regulatory effect on colonic mucosa cell growth, opening the discussion on a pharmacologic approach to colorectal cancer prevention and therapy based on estrogenic compounds. PMID- 30290438 TI - Transcriptional control of the expression of MUC1. AB - MUC1 is a multifunctional cell surface glycoprotein that modulates cell adhesion, protects mucosa from infection and enzymatic attack, lubricates cell surfaces, participates in multiple signal-transduction pathways and is overexpressed by many tumors. MUC1 levels change dynamically in various cellular contexts. The primary mechanism for controlling MUC1 expression appears to be transcriptional through a complex combination of often overlapping regulatory motifs that control both tissue specificity and overall rate of transcription. This review will summarize the current knowledge of the factors known to control MUC1 transcriptional regulation, including cytokines, steroid hormones and the growth factors they stimulate, as well as suggest how this information may be exploited in the future to control MUC1 expression in specific biological contexts. PMID- 30290440 TI - Study results suggest that hypothalamic amenorrhea may have a genetic basis in some women. PMID- 30290439 TI - STAT5 activity in pancreatic beta-cells. AB - Signal transducer and activator of transcription (STAT)5A and -5B are latent transcription factors activated by cytokines and hormones of the cytokine family. In pancreatic insulin-secreting beta-cells, STAT5A and -5B are activated primarily by prolactin and growth hormone stimulation and are important mediators of the potent stimulation of proliferation and insulin production caused by these hormones. STAT5A and -5B are both expressed in beta-cells and control the expression of a number of mRNAs implicated in cell replication control, insulin biosynthesis and secretion. In addition to STAT5A and -5B being transcriptional activators, they may also repress gene transcription. By these means, STAT5 proteins increase the levels of anti-apoptotic transcripts in beta-cells and repress expression of pro-apoptotic genes. This review focuses on the anti apoptotic role of STAT5 signaling, providing a mechanism for beta-cell resistance to pro-apoptotic cytokines, Type 1 diabetes mellitus and obesity-associated beta cell stress. It is clear from studies of STAT5 signaling in pancreatic beta-cells that STAT5 is important for postnatal beta-cell compensatory growth (as in pregnancy or obesity) and in the defense against beta-cell stress factors. PMID- 30290441 TI - A comparison of strontium ranelate and PTH(1-84). AB - Evaluation of: Quesada-Gomez JM, Muschitz C, Gomez-Reino J, Greisen H, Andersen HS, Dimai HP. The effect of PTH(1-84) or strontium ranelate on bone formation markers in postmenopausal women with primary osteoporosis: result of a randomized, open-label trial. Osteoporosis Int. DOI: 10.1007/s00198-010-1460-6 (2010) (Epub ahead of print). A recent article compared parathyroid hormone (PTH[1-84]) and strontium ranelate with respect to their effects on bone formation and bone resorption markers, a study performed with the aim of shedding light on the potential differences in the mode of action of these two compounds. This study found that PTH(1-84) induces robust inductions of both the bone formation markers N-terminal propeptide of type I collagen and alkaline phosphatase, and the resorption marker c-terminal crosslinked telopeptide of type I collagen (CTX-I), data that correlate well with previous publications. However, for strontium ranelate, no induction of markers was observed. Furthermore, although the data were not significant, serum calcium levels in the two treatment groups exhibited opposing trends, with PTH(1-84) increasing these as expected and with strontium ranelate decreasing them. These data indicate that strontium ranelate utilizes another mode of action to the induction of turnover seen with PTH(1-84). Finally, a trend towards improved quality of life was seen with PTH(1 84), while strontium ranelate did not change these parameters. This article is a useful addition to the ongoing debate on how best to possibly treat osteoporosis. PMID- 30290442 TI - Variability in stress system regulatory control of inflammation: a critical factor mediating health effects of stress. AB - Chronic stress has been associated with disease but the biological pathways are not completely understood. Stress systems such as the hypothalamus-pituitary adrenal axis and the autonomic nervous system are prime candidates but alterations in their baseline activity are not consistently found in chronic stress. Evidence suggests that stress-related changes in the sensitivity of inflammatory pathways towards glucocorticoid regulation, that is, the development of glucocorticoid resistance, might help explain inflammatory disinhibition and the subsequent development of disease. Recent data show a similarly important role for sympathetic and parasympathetic modulation of the inflammatory cascade for the maintenance of health. This article argues that variation of target tissue sensitivity towards anti-inflammatory effects of the hypothalamus pituitary-adrenal axis, as well as sympathetic and parasympathetic signaling, might be involved in the development of low-grade inflammation under chronic psychosocial stress. PMID- 30290443 TI - Intraoperative adjuncts for parathyroid surgery. AB - In recent years, parathyroid surgery has evolved from traditional bilateral neck exploration to minimal invasive parathyroidectomy. This trend became possible due to preoperative localization imaging that guides the surgeon in the search for a parathyroid adenoma. Intraoperative adjuncts are complementary to preoperative localization and assist in localizing parathyroid glands, confirming parathyroid tissue and establishing a cure. Institutions and surgeons utilize different intraoperative adjuncts in different protocols with varying results. The purpose of this article is to review the available intraoperative adjuncts to parathyroid surgery and critically evaluate their utility, accuracy and their added value to the surgeon. PMID- 30290444 TI - The efficacy and safety of vildagliptin in the GALIANT trial: chronic kidney disease and other applications. AB - The number of mechanistically novel antidiabetes agents has dramatically increased over the past few years. Dipeptidyl peptidase-4 (DPP-4) inhibitors in particular have emerged as clinically efficacious oral agents for diabetes management with a low incidence of side effects. The Galvus in Addition to Metformin versus Tzd/Metformin in Lowering HbA1c (GALIANT) trial showed that vildagliptin as an add-on therapy was noninferior to thiazolidinedione therapy with regard to reduction in hemoglobin A1c, with both drugs having a similar incidence of side effects in patients with normal and impaired renal function. DPP-4 inhibitors have a low incidence of hypoglycemia without significant weight gain and there is strong evidence that the administration of vildagliptin results in improved alpha- and beta-cell function. New data suggest that DPP-4 inhibitors might also have a role in the setting of myocardial infarction and lipid management, and in the prevention of Type 2 diabetes. PMID- 30290445 TI - Osteocalcin: an endocrine link between bone and glucose metabolism. AB - Impaired glucose metabolism is common and contributes to the risk of diabetes and cardiovascular disease. Deletion of the gene for the osteoblast-derived protein, osteocalcin, leads to insulin resistance in mice, while the addition of osteocalcin increases insulin secretion from beta-cells and adiponectin expression in adipocytes. Osteocalcin deficiency in gamma-carboxyl groups, undercarboxylated osteocalcin, was found to improve insulin secretion and sensitivity in experiments. Recent studies have examined the relevance of these findings to glucose metabolism and cardiovascular risk in humans. Low total osteocalcin levels are associated with insulin resistance, diabetes and metabolic syndrome in observational studies. New therapeutic approaches to diabetes and heart disease may be anticipated if this bone-derived protein is involved in the regulation of glucose metabolism and cardiovascular risk. PMID- 30290446 TI - Physiological effects of Type 2 diabetes on mRNA processing and gene expression. AB - Characteristics of Type 2 diabetes include both high blood glucose (hyperglycemia) and raised cholesterol and triglycerides (hyperlipidemia). Several studies have now shown that both hyperglycemia and hyperlipidemia can alter gene expression by disrupting physiological mechanisms of gene regulation, including alternative mRNA splicing, epigenetic gene regulation and miRNA mediated regulation of gene expression. These processes may also be influenced by intracellular oxidative stress, which is increased in diabetes and in response to hyperglycemia and hyperlipidemia. Many pathways relevant to diabetes are affected by altered gene expression, including lipid and glucose metabolism and oxidative phosphorylation. This article considers how hyperglycemia and hyperlipidemia can alter gene expression in diabetes, which could potentially contribute to the worsening of the diabetic phenotype and diabetic complications. PMID- 30290447 TI - Gender differences in thyroid cancer: a critical review. AB - It has long been known that the incidence of thyroid cancer in women is significantly higher than that in men. The objective of this article is to review gender differences in thyroid cancer, as well as epidemiological, clinical and experimental research on the role of sex hormones, their receptors and other molecular factors in this well-established thyroid cancer gender discrepancy. Although more common in women, thyroid cancer typically presents at a more advanced stage and with a worse disease prognosis in men. Clinical evidence on the impact of estrogen and other sex hormones on thyroid cancer has remained inconclusive, although numerous experimental studies have suggested that these hormones and their receptors may play a role in tumorigenesis and tumor progression. Studies of thyroid cancer cell lines suggest that an imbalance between the two estrogen receptor (ER) isoforms, alpha and beta, may be responsible for the cell proliferation seen with estrogen treatment. Expression studies on thyroid tumors indicate that they express ER and possibly progesterone receptors and androgen receptors, but there is conflicting evidence as to whether or not there is a difference in receptor status between thyroid cancers, benign thyroid lesions and normal thyroid tissue. There have been few studies evaluating the ERalpha/ERbeta profiles in thyroid tumors and normal thyroid tissue. Our understanding of the underlying basis for sex differences in thyroid cancer has improved over the last few decades, but the relationship between gender and thyroid cancer risk has remained elusive. Areas for future research include ERalpha/ERbeta profiling of normal and neoplastic thyroid tissue, association between ER status and tumor dedifferentiation, and evaluation of the signaling pathways by which estrogen and other sex steroids exert their effects on thyroid cancer cells. Sex steroid receptors, and then downstream signaling pathways, represent promising future therapeutic targets for thyroid cancer treatment, and further study is required. PMID- 30290449 TI - Oral contraceptives in polycystic ovarian syndrome: the long and short of it. PMID- 30290450 TI - Postradiation therapy hypopituitarism. AB - The increasing use of radiation treatment for head and neck cancers and other tumors, including pituitary adenomas, from the mid-20th Century onwards led to the recognition that pituitary function may be affected - often leading to some degree of pituitary insufficiency. Our knowledge is mostly based on observational or retrospective rather than randomized prospective studies. The various axes may be impacted at the hypothalamic or pituitary levels, or both. Some axes - the somatotropic and gonadotropic - appear to be especially vulnerable to radiation damage and may be affected quite early, whereas posterior pituitary function is rarely affected. Increased use of stereotactic radiosurgery, which focuses the radiation dose on the abnormal tissue, may be expected to reduce the impact on normal pituitary function, but such studies that are available are, as yet, relatively short term. Prospective studies of the effect of stereotactic radiosurgery on pituitary function would be valuable. PMID- 30290451 TI - Genetic susceptibility in pituitary adenomas: from pathogenesis to clinical implications. AB - Pituitary adenomas usually present sporadically, with a multifactorial pathogenesis including somatic mutational events in cancer-related genes. Genetic predisposition implies the presence of germline DNA alterations with a range of impacts on pituitary cell biology, translating into a variable penetrance of the disease. Genetic causes must be considered in the presence of specific clinical settings, such as familial occurrence of pituitary adenoma, with or without extrapituitary diseases, and may also be suspected in young patients (<30 years of age) with macroadenomas. We review the clinical implications of genetic predisposition, with special attention on multiple endocrine neoplasia type 1, Carney complex and familial isolated pituitary adenoma. Genetic screening in selected patients with an apparently sporadic disease is also discussed. PMID- 30290453 TI - Bremelanotide: the female Viagra? PMID- 30290452 TI - Osteoporosis following organ transplantation: pathogenesis, diagnosis and management. AB - Organ transplantation has become popular for the management of various chronic illnesses. With the advent of modern immunosuppressive treatments, the longevity of transplant recipients has increased. Consequently, morbid complications such as osteoporosis and bone fractures are seen at an increasing frequency in this population. In most transplant recipients, bone mineral density (BMD) falls shortly after transplantation. However, bone fracture rate plateaus in all except for post-renal transplant patients. Although the underlying pathophysiologic mechanism for this difference is not fully understood, potential mechanisms for sustained bone loss in renal transplant recipients may be persistent phosphorus wasting and defective bone mineralization. Current treatment regimens are based on studies in a small numbers of subjects with BMD as the primary outcome. Although BMD is recognized as a gold standard in the assessment of bone fracture risk, to date, its association with bone fracture risk in the general post transplant population is not robust. Therefore, randomized controlled trials with bone fracture as the primary end point are crucial. The development of noninvasive bone markers in distinguishing bone turnover and bone mineralization status is also pivotal since skeletal lesions are heterogeneous in various organ transplantations. The elucidation of these underlying skeletal lesions is necessary for the consideration of selective treatment in this population. PMID- 30290454 TI - Ion channels of primate ovarian endocrine cells: identification and functional significance. AB - Ion channels are crucially involved in cellular functions, but little is known about molecular identity, subunit composition and the specific role of ion channels in ovarian endocrine cells in human and nonhuman primates. Using human luteinizing granulosa cells, a few groups have started to address these questions and have begun to show molecular identity of ion channels, electrophysiological functions and the relationship to hormone production, as well as regulation by hormones and intraovarian factors. Functional ion channels that have been identified so far include T- and L-type Ca2+ channels (Cav3.2, Cav1.2), a voltage dependent Na+ channel (Nav1.7), as well as voltage- (Kv4.2) and Ca2+-dependent K+ channels (BKCa). Since all these ion channels were found to be involved in steroid hormone synthesis and are expressed by endocrine ovarian cells in human and nonhuman ovary, it has been proposed that they are physiological key molecules for ovarian function. Furthermore, they may be novel targets for modulating ovarian functions. PMID- 30290455 TI - Proteomics for diabetes research: an update and future perspectives. AB - Diabetes is a common disease worldwide and can cause several complications, leading to systemic derangements and end-organ damage. Despite blood sugar control and adequate therapy with currently available drugs, diabetic complications remain a serious issue in clinical practice, indicating that our knowledge of diabetes and its complications is only at the tip of the iceberg. Better understanding of its pathogenesis and pathophysiology is crucial to achieve better therapeutic outcomes and to prevent its complications. This review provides an overview of proteomics and introduces proteomic technologies commonly used for diabetes research. Recent proteomic studies for the investigation of diabetes and its complications are summarized. Finally, the future perspectives for the field of proteomics in diabetes research are discussed. PMID- 30290456 TI - Obesity, insulin resistance, Type 2 diabetes and free fatty acids. AB - High levels of free fatty acids have emerged as a major link between obesity and insulin resistance/Type 2 diabetes. In pancreatic beta cells, free fatty acids potentiate glucose-stimulated insulin secretion precisely to the extent needed to compensate for the free fatty acid-induced insulin resistance. It is postulated that this prevents the development of Type 2 diabetes mellitus in the majority of obese, insulin-resistant individuals who have free fatty acid-mediated insulin resistance. In individuals with inherited defects of beta-cell function (prediabetics), this compensation fails and hyperglycemia develops. Elevated levels of free fatty acids also activate the proinflammatory and proatherogenic nuclear factor kappaB pathway. Thus, elevated plasma levels of free fatty acid in obese people can produce a low-grade inflammatory state, which may contribute to accelerated atherosclerosis (coronary artery disease, strokes and peripheral arterial disease) and to nonalcoholic steatohepatitis; these conditions are increased in obesity. PMID- 30290457 TI - Syndrome of inappropriate antidiuresis. AB - The syndrome of inappropriate antidiuresis is the most common cause of euvolemic hyponatremia and complicates a wide spectrum of diseases and neurosurgical conditions. The syndrome is characterized by clinical euvolemia, dilute plasma osmolality and inappropriately concentrated urine, with normal renal, adrenal and thyroid function. Hyponatremia in syndrome of inappropriate antidiuresis represents an excess of plasma water, rather than sodium deficiency. The severity of hyponatremia is limited by renal escape from antidiuresis. Treatment varies according to symptoms, severity and speed of onset of hyponatremia. Acute, severe, symptomatic hyponatremia may require rapid treatment with hypertonic saline, with care to avoid central pontine myelinosis. Chronic hyponatremia is managed with fluid restriction and demeclocycline for unresponsive cases. Vasopressin antagonists represent a new option for chronic hyponatremia of syndrome of inappropriate antidiuresis. PMID- 30290458 TI - Targeting 11beta-hydroxysteroid dehydrogenase type 1 in brain: therapy for cognitive aging? AB - Dementia care costs exceed those of cardiovascular diseases and cancer combined. Milder forms of functionally significant cognitive decline add further to the staggering human, societal and economic costs. However, the underlying mechanisms are poorly understood and few treatments are available. Cumulative exposure to high glucocorticoid levels is a major hypothesis of decline in cognitive function with aging. Current manipulations to maintain low circulating glucocorticoid levels throughout life (adrenalectomy with low-dose corticosterone replacement and neonatal handling), although effective in preventing the emergence of memory deficits with age in rodent models, are not clinically applicable. By contrast, recent data in cells, mice and humans suggest that inhibition of the tissue selective glucocorticoid-amplifying enzyme, 11beta-hydroxysteroid dehydrogenase type 1, may be an effective novel approach. PMID- 30290459 TI - Endocannabinoid system and its role in energy regulation. AB - Endocannabinoids are endogenous agonists for the two types of cannabinoid receptors identified to date, the CB1 and CB2 receptors. CB1 receptors and tissue concentrations of endocannabinoids sufficient to activate them are present in the brain structures controlling energy intake (i.e., the hypothalamus, nucleus accumbens and nodose ganglion), as well as in all peripheral organs mostly involved in the regulation of energy homeostasis (i.e., the duodenum, small and large intestine, adipose tissue, skeletal muscle, pancreas and liver). Several peripheral neuropeptides and hormones involved in energy balance, and type of diet, regulate endocannabinoid levels, whereas endocannabinoids, in turn, regulate the expression and release of hypothalamic mediators involved in nutrient intake. Dysregulation of the endocannabinoid system might contribute to the development of eating disorders and explain why CB1 receptor blockers are efficacious at reducing not only food intake but also the metabolic consequences of visceral adiposity and obesity. PMID- 30290460 TI - Role of inhaled human insulin in the management of Type 1 and 2 diabetes. AB - Inhaled human insulin (Exubera(r)) has been approved by the FDA and other regulatory bodies for treatment in Type 1 and 2 diabetes in the USA. It is the first alternative to injectable insulin since the discovery of the insulin compound to treat diabetes. This article will review results of recent clinical studies that support the therapeutic efficacy and safety of inhalable insulin for use in patients with diabetes. The pharmacological profile of inhaled insulin with particular reference to inhaled human insulin and the potential to influence diabetes care is also discussed. PMID- 30290461 TI - Neuroactive steroids as modulators of depression and anxiety. AB - In addition to the well-known genomic effects of steroid molecules, certain neuroactive steroids control neurotransmission through the modulation of specific neurotransmitter receptors. Preclinical studies suggested that neuroactive steroids may modulate anxiety and depression-related behavior and may contribute to the therapeutic effects of antidepressant drugs. However, nonpharmacological antidepressant treatment strategies did not affect neuroactive steroid composition. These studies suggest that the changes in neuroactive steroids observed after antidepressant pharmacotherapy probably reflect distinct pharmacological properties of antidepressants, rather than the clinical response. Nevertheless, initial studies investigating the antidepressive effects of exogenously administered dehydroepiandosterone revealed promising results. In addition, in various anxiety disorders, alterations of neuroactive steroid levels have been observed. In conclusion, neuroactive steroids contribute to the pathophysiology of affective disorders and the mechanisms of action of antidepressants. They are important endogenous modulators of depression and anxiety and might offer new targets for the development of novel anxiolytic compounds. PMID- 30290462 TI - Report on the 2nd Annual Metabolic Diseases World Summit. PMID- 30290463 TI - Rapid-acting insulin glulisine: a new tool for postprandial glucose control. AB - Insulin glulisine (Apidra(r), Sanofi-Aventis) is a novel, rapid-acting insulin analog that replicates normal mealtime insulin secretion more closely than regular human insulin. Compared with regular human insulin, glulisine has a more rapid onset of action and shorter duration of effect, affording greater flexibility in the timing and content of meals. Additionally, optional pre- or postmeal administration makes glulisine well suited for patients who eat erratically or have difficulty remembering premeal injections. This attribute is clinically relevant because addressing postprandial hyperglycemia may help attenuate cardiovascular morbidity and mortality among diabetic patients. Insulin glulisine is safe when used for pump therapy and its rapid-acting properties are maintained consistently across patient types and body mass indices, making it an effective and versatile tool for postprandial glucose control. PMID- 30290464 TI - Pegvisomant therapy for acromegaly. AB - Despite traditional, multimodality therapy that consisted of surgery, radiotherapy and medical therapies, many patients with acromegaly could not be adequately treated. Pegvisomant is a novel growth hormone receptor antagonist that became available for the treatment of acromegaly in 2003. This drug is a growth hormone variant that has nine mutations to human growth hormone. These give it high affinity for the growth hormone receptor as well as disrupting growth hormone receptor dimerization, with the net effect being antagonism of growth hormone at its receptor. Traditional methods of therapy for acromegaly treat the disease by reducing pituitary tumor secretion of growth hormone and, thus, lowering serum insulin-like growth factor-I levels. Pegvisomant, by contrast, blocks the actions of circulating growth hormone excess, but does not lower serum growth hormone levels. Its efficacy, therefore, is assessed by monitoring serum insulin-like growth factor-I levels. In clinical trials, pegvisomant has been shown to effectively normalize insulin-like growth factor-I levels in up to 97% of patients and to improve acromegaly-related signs and symptoms, and morbidities such as insulin resistance. As the action of pegvisomant does not rely on the tumor's receptor profile, it can be effective even in patients resistant to somatostatin analog therapy. Individually tailored therapy guided by serum insulin-like growth factor-I normalization goals and improvement in clinical signs and symptoms should be undertaken while growth hormone deficiency should be avoided. Pegvisomant is very well tolerated, but liver transaminase levels need to be monitored during therapy. As pegvisomant does not shrink pituitary tumors, the underlying rate of tumor growth may continue on this therapy and periodic pituitary imaging needs to be conducted during therapy. PMID- 30290465 TI - Sleep loss, obesity and diabetes: a fatal connection? PMID- 30290466 TI - Potential new diabetes treatment discovered during study of leptin. PMID- 30290467 TI - How growth hormone may be linked to cancer: concerns and perspective. AB - Recent evidence from epidemiology indicates that inter-individual variations in the growth hormone (GH)/IGF-I pathway affect the risk of individuals developing common epithelial cancers. This is supported by associations between normal common variants within genes from the pathway and these cancers, which excludes many potential confounding issues, such as reverse causality. This raises concern for the increasing numbers of patients treated with GH; although replacement therapy for GH-deficiency should aim to restore normality, which should then only incur a normal risk. The links with cancer also offers promising new opportunities. Clinical trials treating cancer patients with pharmaceuticals targeting the IGF-I receptor are well advanced with promising initial findings. In the future, there has to be much more emphasis within oncology on prevention and the GH/IGF-I pathway is one of few identified risk factors that are modifiable, not just by pharmaceutical, but also nutritional, interventions that may, in the long term, be more appropriate. Assessing the status of the GH/IGF-I pathway in individuals may also provide a means for targeting screening programs and preventative measures. PMID- 30290468 TI - Phenylketonuria: questioning the gospel. AB - Phenylketonuria (PKU) was first described over 70 years ago, treatment was developed 50 years ago and universal newborn PKU screening was introduced 40 years ago. Phenylalanine-restricted dietary treatment has prevented mental retardation in thousands of individuals worldwide. We acknowledge, however, that there is still much to learn in the field. The incidence of mental retardation in untreated PKU is likely to be considerably less than the original estimates. Since dietary control is suboptimal in late childhood, adolescence and adulthood, alternative methods of treatment are being explored. These include large neutral amino acids, phenylalanine ammonia lyase, tetrahydrobiopterin and gene replacement. Evidence has surfaced that the semisynthetic, low-protein diet used to treat PKU may be deficient in certain important nutrients. Maternal PKU treatment may be successful even if initiated as late as 8-10 weeks into pregnancy. A plea is made for the immediate establishment of adult treatment centers for PKU (and other inherited metabolic diseases) for long-term treatment, follow-up and research. PMID- 30290469 TI - Advances in medical treatment of Cushing's disease. AB - It is well known that transphenoidal surgery is the first line of treatment for Cushing's disease (CD). In case of recurrence, pituitary irradiation or adrenalectomy are usually performed; however, the morbidity due to these procedures is not negligible. For this reason, there is still a strong need for medical therapy, although there are only a few controlled data on this field. A variety of compounds are invaluable complementary tools in the management of this serious condition for which no treatment has yet been proven fully satisfactory. Pharmacological treatment could be employed by using neuromodulatory drugs (i.e., serotonin antagonists, dopamine, and GABA agonists) active only in a few cases of hypothalamic-pituitary-dependent CD. New approaches at the pituitary tumor level involve the potential use of other compounds (e.g., PPAR-gamma agonists and retinoic acid). Exciting news in treating CD includes the recent availability of new multiligand somatostatin analogues. This review focuses on the new potential pharmacologic approaches for the management of CD based on the recent identification of possible targets and/or pathogenetic mechanisms. PMID- 30290470 TI - Screening and diagnosis of primary aldosteronism. AB - Primary aldosteronism (PA) is the most common cause of mineralocorticoid hypertension. Different studies using the plasma aldosterone concentration (PAC) plasma renin activity ratio (ARR ratio) for the screening of patients with hypertension, have shown a marked increase in the detection rate of PA. PA is commonly caused by an adrenal adenoma (APA) or idiopathic bilateral adrenal hyperplasia of the adrenal zona glomerulosa (IHA) and, in rare cases, by the inherited condition of glucocorticoid-remediable aldosteronism (GRA). The early diagnosis of PA is important, not only because the forms caused by adrenal adenoma are surgically curable, but also because correlation between the duration of PA and the development of cardiovascular complications has been reported. Patients with resistant and/or severe hypertension, patients with hypokalemia, those with a family history of hypertension and stroke at an early age, or patients with an adrenal incidentaloma should be screened for PA using the ARR ratio. Suspicion of PA owing to a pathological ratio requires confirmatory testing, including fludrocortisone suppression test, saline infusion and captopril challenge. Adrenal gland imaging is important in subtype differentiation (APA vs IHA), but adrenal venous sampling is the gold standard and should be used when other tests prove inconclusive. Genetic testing has facilitated detection of GRA. PMID- 30290471 TI - Polycystic ovary syndrome: a focus on anti-Mullerian hormone levels. AB - Anti-Mullerian hormone (AMH) is a dimeric glycoprotein exclusively produced by the granulosa cells and reflects the size of the growing follicular pool. Serum AMH levels seem to correlate with the development of preantral and small-antral follicles during reproductive life. It has been established that AMH levels are two- to threefold higher in adult women with polycystic ovary syndrome (PCOS) compared with healthy women. This may be related to an increased number of growing follicles that secrete AMH or to an increased per granulosa cell production. Therefore, the understanding of its regulation is important to advance the comprehension of PCOS pathophysiology. Apparently, androgens may play an important role in this regard. Recently, our group documented higher serum levels of AMH in daughters of women with PCOS compared with control girls during three stages of sexual development, early infancy, childhood and peripuberty, suggesting the presence of an increased growing follicular pool in these girls that is established early in development and precedes the onset of clinical hyperandrogenism. In addition, clinical and experimental studies suggest that androgens could also have a role in determining an increased follicular mass during prenatal life, which, during postnatal life, may perpetuate hyperandrogenism. Currently, AMH determination is being progressively used in clinical practice as a marker of ovarian function. In the future, it may become a useful tool to assess ovarian aging and reserve, to diagnose PCOS and to evaluate treatment success. PMID- 30290472 TI - Characteristics of familial isolated pituitary adenomas. AB - The familial occurrence of pituitary adenomas has been recognized for many years and currently accounts for approximately 5% of all cases. Molecular, genetic and clinical features of familial pituitary adenomas have been well characterized in multiple endocrine neoplasia type 1 (MEN-1) and Carney's complex (CNC), which account for the majority of familial pituitary tumor cases. These conditions are caused by MEN1 and PRKAR1A gene mutations, respectively, and the clinical and pathological features of pituitary pathology in these diseases differ from those of sporadic pituitary tumors. Familial acromegaly has been recognized for many years and, more recently, the clinical features of this clinical phenotype, referred to as isolated familial somatotropinoma, have been clarified. Over the past decade, the concept of non-MEN-1/CNC familial pituitary tumors has been expanded significantly to include all phenotypes, a condition known as familial isolated pituitary adenomas (FIPA). In FIPA, tumors can present homogeneously (same phenotype) or heterogeneously (different tumor phenotypes) within the same family. Compared with sporadic pituitary adenomas, patients with FIPA have a younger age at diagnosis and have larger tumors. The clinical features of FIPA differ from those of MEN-1 in terms of a higher frequency of somatotropinomas and a lower frequency of prolactinomas. The recent discovery of the involvement of mutations in the aryl hydrocarbon receptor interacting protein (AIP) gene in association with pituitary tumors has provided new information regarding potential mechanisms of tumorigenesis in FIPA patients. While very infrequent in sporadic pituitary tumors, approximately 15% of FIPA patients have AIP mutations, rising to half of patients with familial acromegaly. In this review, we detail the clinical features of FIPA and discuss tumor pathology and genetic findings in this increasingly recognized clinical condition. PMID- 30290473 TI - Defective functional beta-cell mass and Type 2 diabetes in the Goto-Kakizaki rat model. AB - Increasing evidence indicates that decreased functional beta-cell mass is the hallmark of Type 2 diabetes mellitus. Therefore, the debate focuses on the possible mechanisms responsible for abnormal islet microenvironment, decreased beta-cell number, impaired beta-cell function and their multifactorial etiologies. The information available on the Goto-Kakizaki/Par rat line, one of the best characterized animal models of spontaneous Type 2 diabetes mellitus, are reviewed in such a perspective. We propose that the defective beta-cell mass and function in the Goto-Kakizaki/Par model reflect the complex interactions of multiple pathogenic players, including several independent loci containing genes responsible for some diabetic traits (but not decreased beta-cell mass), gestational metabolic impairment inducing an epigenetic programming of the pancreas (decreased beta-cell neogenesis), which is transmitted to the next generation, and loss of beta-cell differentiation due to chronic exposure to hyperglycemia, inflammatory mediators, oxidative stress and perturbed islet microarchitecture. PMID- 30290474 TI - International Society of Psychoneuroendocrinology Conference 2007. PMID- 30290475 TI - Role of nuclear receptor coregulators in metabolism. AB - Understanding the molecular regulation of metabolism will lead to a better understanding of the pathogenesis and treatment of common metabolic conditions, including obesity and diabetes. Nuclear receptors are a family of transcription factors, many of which play major roles in regulating metabolic genes in key tissues. They function by recruiting coregulators to the promoters of metabolic genes that can either activate or repress transcription. This review examines the roles of these coregulators in the control of metabolism in adipose tissue and skeletal muscle, and discusses how they result in coordinated and regulated control of metabolic pathways. In particular, the ligand-dependent recruitment of both coactivators and corepressors has potential implications for the treatment of obesity and diabetes. PMID- 30290476 TI - Systemic and endocrine manifestations of Langerhans' cell histiocytosis: current concepts in diagnosis and management. AB - Langerhans' cell histiocytosis (LCH) is a rare disease of unknown etiology and variable biologic behavior and course. Almost every organ can be affected; however, it frequently involves the bones, lungs, skin and lymph nodes. LCH exhibits a particular predilection for involvement of the hypothalamo-pituitary axis resulting in diabetes insipidus and/or other anterior pituitary deficiencies. Although LCH can sometimes resolve spontaneously, it usually follows a chronic course and systemic treatment is mandatory for the management of multisystem disease. However, a significant number of patients will develop at least one permanent sequela as a consequence of the disease, with diabetes insipidus being the most common. A multidisciplinary approach is always needed in diagnosis, treatment and follow-up of all patients with LCH. PMID- 30290477 TI - The future of forensic mental health services in Ireland. PMID- 30290478 TI - Psychiatric morbidity among women prisoners newly committed and amongst remanded and sentenced women in the Irish prison system. AB - OBJECTIVES: To estimate the prevalence of psychiatric morbidity, substance misuse problems and related health and social problems among women prisoners newly committed and a cross-section remanded and sentenced in the Irish prison population. In 2002 women represented 10.7% (1043) of all persons committed to the Irish Prison system, and 3.3% (104) of the daily average number of persons in custody. We surveyed psychiatric morbidity in these two groups to assess the need for psychiatric services for women prisoners, and to compare Irish morbidity with an international average. METHOD: We interviewed 94 newly committed women prisoners within 72 hours of committal, representing approximately 9% of female committals per year. We also interviewed a cross sectional sample of 92 women, representing approximately 90% of all women in custody. Mental illness and substance misuse was measured using the SADS-L, SODQ and a structured interview. RESULTS: Five (5.4%) of the committal and 5 (5.4%) of the cross-sectional sample had a psychotic illness within the previous six months. 8 (8.5%) of the committals and 15 (16.3%) of the women in the cross-sectional sample had a major depressive disorder in the last six months. 8 (8.6%) committals and 14 (15.2%) in the cross-sectional sample had an anxiety disorder within the last six months. 61 (65.6%) of the women interviewed at committal and 61 (65.2%) of the cross sectional sample had a substance misuse problem in the last six months. CONCLUSIONS: There is a high prevalence of mental illness and substance misuse problems amongst women newly committed to prison and in a cross section of those remanded or sentenced in prison in Ireland. We found evidence of a cycle of deprivation and institutionalisation. These findings highlight the need for the integration of community and forensic psychiatric services, and for ongoing collaboration with drug services. PMID- 30290479 TI - Psychiatric morbidity in the male sentenced Irish prisons population. AB - BACKGROUND: This is the first epidemiologically representative cross-sectional study of psychiatric morbidity using research diagnostic instruments in sentenced prisoners in Ireland. OBJECTIVE: To estimate the prevalence of psychiatric morbidity and psychiatric service requirements. METHOD: We interviewed 340 men serving a fixed sentence (14.6% of total) and 98 men serving a life sentence (82% of total). Prisoners were drawn from 15 different prisons using a random stratified sampling method. Mental illness and substance misuse was measured using the SADS-L, SODQ and a structured interview to generate ICD-10-DCR diagnoses. RESULTS: We found a high prevalence of mental illness. Our six month prevalence for psychosis (2.7%) was similar to an international meta-analysis. We found a significantly higher prevalence of psychosis in life sentenced prisoners (6.1%) compared to fixed sentenced prisoners (1.8%). Drugs and alcohol problems were very prevalent. CONCLUSIONS: Using the six month prevalence figures found for psychosis, we estimate that there are approximately 79 sentenced male prisoners with a severe mental illness who would require treatment in hospital additional to current provision. We discuss the relationship between drug availability and the prevalence of severe mental illnesses in prisons. PMID- 30290480 TI - Drug treatment programmes in prison: longitudinal outcome evaluation, policy development and planning interventions. AB - AIMS: The aim of this research is to evaluate a seven week abstinence-based drug treatment programme and to use this to assist policy makers in the planning and provision of future programmes. METHODS: Design: Seventy-nine clients were interviewed at two stages. Stage I, prior to the treatment programme, stage II, immediately after the treatment programme. A selected group of 20 clients were followed-up and interviewed at stage III, up to 24 months after the treatment programme. SETTING: All clients were prisoners at Mountjoy Prison, Dublin Ireland. PARTICIPANTS: Seventy-nine male prisoners were recruited. A sample of 20 of the original cohort of 79 was selected using a snowball sampling method approximately 24 months following treatment. This latter sample of 20 clients consisted of eight prisoners who had re-offended and returned to prison, three prisoners who were still in prison serving their original sentence and nine prisoners who were out of prison. These 20 also participated in a more detailed quantitative and qualitative survey. MEASUREMENTS: In order to measure prisoner's criminogenic attitudes and needs the Crime Pics II instrument was used. This is a semantic differential scale which measures attitudes toward offending behaviour. It includes a problem checklist which can be used to measure change over time. RESULTS: An 82% follow-up rate was achieved on the original group of 79 clients, similarly a follow-up rate of 100% was also achieved for the selected group of 20 clients who were interviewed three times. Regardless of category of client, findings demonstrate an improvement over time for the outcome variables, general attitude to offending, anticipation of re-offending and perception of current life problems. However, the study failed to demonstrate any significant change for the outcome variables victim hurt denial and evaluation of crime as worthwhile. CONCLUSIONS: These results were short lived for many prisoners, who failed to sustain the gains made. Interviews with the cohort of 20 who underwent stage III interviews possibly suggest that those clients who did not receive continuity of treatment post programme, in terms of case management and structured treatment did not fare as well as those who did. PMID- 30290481 TI - Variations in residential accommodation for adults with intellectual disabilities: the example of Northern Ireland. AB - OBJECTIVES: Over the past three decades, major changes have taken place internationally in the type of residential accommodation provided for people with intellectual disabilities but these appear to be less evident in Northern Ireland. METHOD: A census was undertaken of all persons in any form of residential placement using a range of existing databases to identify the population, with a short questionnaire completed for each resident. RESULTS: Around 440 persons lived in hospitals and 1,970 in some other form of provision but mostly in large congregated settings such as residential care homes and nursing homes. This was more marked in certain Health and Social Service Boards than in others. Most places are provided by the private sector although voluntary organisations and housing associations now manage around one-third of places. People living in hospitals reportedly had different characteristics to those in all other settings while those in nursing homes tended to require greater personal care. However the characteristics of people living in residential homes, supported living arrangements and village communities were broadly comparable. Around one in 10 persons were deemed to benefit from a move; mostly from residential homes to more independent living arrangements. CONCLUSIONS: Compared to Britain and the Republic of Ireland there is an under-provision of residential placements in Northern Ireland. To date, funding from outside of health and social services has been the main driver for the type of accommodation provided. The implications for future policy and provision are discussed. PMID- 30290482 TI - Psychiatry in contemporary Irish cinema: a qualitative study. AB - OBJECTIVE: Media portrayals of mental illness and psychiatry have a considerable impact on public perceptions of mental health issues. This paper aims to focus on portrayals of psychiatry and psychiatrists in four contemporary Irish feature films in order to make wider points on this theme. METHODS: Contemporary Irish feature-films that made substantial reference to psychiatry, psychiatrists or mental health in Ireland were identified though electronic searches and consultation with the Film Institute of Ireland. Selected films were viewed. Electronic searches were performed in the medical and film literatures, with broad search terms related to film, psychiatry, psychiatrists or mental health in Ireland. Additional books and papers were identified by tracking back through references and consulting with colleagues. RESULTS: The portrayal of psychiatrists in film is closely related to the development of both twentieth century psychiatry and twentieth century cinema. In common with recent European films, certain recent Irish films have tended to show psychiatrists as sympathetic, humane individuals (with some notable exceptions). While there have been a number of portrayals of dissocial personally disorder and various states of chronic alienation in recent Irish film, there have been fewer portrayals of psychosis or learning disability. Recent Irish films emphasise the role of alcohol in causing and perpetuating psychological distress. They generally provide unflinching portrayals of the effects of psychological distress and alienation, suicide and substance abuse at individual, family and community levels; nonetheless, there is still a regrettable tendency for films to associate mental illness with dissocial behaviour. CONCLUSIONS: The portrayal of mental health issues in film presents both challenges and opportunities to film-makers, mental health service-users and general audiences alike. It is to be hoped that the recent trend towards realistic explorations of mental health issues in many European films continues into the future. Increased research in this area would help clarify the role of cinema in shaping public understandings of mental illness, and may also help identify additional ways of addressing stigma in the future.

AB - OBJECTIVES: To examine a sample of adults with mental health disorders attending at an area psychiatric service, for the presence of impairments in language, communication and swallowing, using a test battery administered by speech and language therapists. METHOD: The study surveyed a randomly selected sample (n = 60) of patients from an acute psychiatric inpatient unit and associated community services, using several standardised measures of language, communication and swallowing. RESULTS: On this test battery, over 80% (50/60) of subjects studied demonstrated impairment in language; while over 60% (37/60) presented with impairment in communication and discourse. Over 30% (18/58) of subjects assessed showed some impairment in swallowing. CONCLUSION: Use of this test battery confirmed the presence of language, communication and swallowing impairments in many patients in this sample of attenders at a general psychiatry service. We suggest that this study provides evidence for a (currently unmet) need for specialist speech and language therapy assessment and support among this patient population. PMID- 30290488 TI - Information sharing and risk: a survey of psychiatrists. AB - OBJECTIVES: Historical information is central to decision making in mental health care. Clinical information in the Irish mental health services is currently mostly paper based. Mental health care in Ireland has moved from an institutional medical model towards a community based multidisciplinary model in recent years. This change has resulted in a dispersal of information between multiple sites and professionals, rendering it less accessible, particularly in emergency settings. This study sought to find out if psychiatrists working in Ireland were experiencing information problems, their ideas about and attitudes towards electronic solutions to these problems, and their views as to what particular pieces of information are indispensable in emergency mental health assessments. METHOD: A questionnaire was designed to answer these questions and sent to a representative sample of 150 psychiatrists working in Ireland. RESULTS: One hundred and nineteen questionnaires (79.3%) were returned complete. Of the 119 respondents 98(82.4%) stated that they had performed emergency mental health assessments within the past year without access to key information and 79(66.4%) said they would have made different decisions in some cases had they had all the available information. Information deficits were particularly apparent in liaison and forensic psychiatry. Of the respondents 110(92.4%) stated that they would welcome an electronic database designed to support emergency mental health assessments. Misgivings were expressed regarding forms of consent, data quality, breach of confidentiality, resources and much more. Risk factors (ie. self-harm potential), a high alert message and medication details were the data items thought to be most critical. CONCLUSIONS: A shareable set of essential pieces of information (a minimum data set) would offer a balance between patient safety, confidentiality and shareability. A wider debate about solutions to the information deficits in mental health care in Ireland needs to take place among all stakeholders so that this idea can be moved forward. PMID- 30290489 TI - Electroconvulsive therapy: International guidelines, clinical governance and patient selection. AB - Recent reports from the Inspector of Mental Health Services have highlighted marked variations in electroconvulsive therapy (ECT) prescriptions nationally. This article reviews six international guidelines in order to assess the question of which patients should be referred for ECT treatment and at what stage in their illness. The guidelines display a general consensus in terms of the acutely and severely ill, but differ dramatically in terms of access to ECT outside this category, such as the moderately depressed patient who is treatment resistant but non-psychotic and non-suicidal and who requests ECT due to a previous good response. The American Psychiatric Association guidelines strongly support the early consideration and use of ECT, highlighting the dangers associated with increased length of illness for individual prognosis. The National Institute of Clinical Excellence (UK) guidelines are the strictest, reserving ECT for the severely ill exclusively and only in cases with a demonstrable failure of alternative treatments. This confusion may ultimately need to be addressed by the Mental Health Commission as data relating to variations in practice may result in inappropriate reductions in access to an established treatment.

AB - The Richmond Asylum (St Brendan's Hospital) in Grangegorman, Dublin was established in 1815 to help address the unmet needs of the mentally ill in 19th century Ireland. This paper examines the Richmond Asylum Joint Committee Minutes from 1907 in order to explore specific aspects of management and clinical activity at the Richmond Asylum, including: (a) patient populations in the asylums; (b) staffing and management issues; (c) challenges presented by workhouse populations in the early 20th century; and (d) the clinical 'segregation' of patients performed by the Medical Superintendent, Dr Conolly Norman, in 1907. PMID- 30290491 TI - Disulfiram induced peripheral neuropathy: between the devil and the deep blue sea. AB - Disulfiram is widely used for the aversive treatment of alcoholism. It is well tolerated in most patients; however 1:15,000 will develop peripheral neuropathy, which is frequently misdiagnosed as alcoholic neuropathy. Most cases present with a motor-sensory neuropathy of the lower limbs, which tends to improve when administration ceases, though some cases may be left with permanent sequelae. This adverse reaction can be avoided by using the lowest effective dose. A literature review using the Medline revealed 66 citations relating disulfiram to peripheral neuropathy, and the number of cases reported is small.

AB - OBJECTIVES: This study evaluated the effectiveness of group cognitive behavioural therapy (GCBT) for the treatment of anxiety disorders in children over an initial period of 12 weeks and to one-month follow-up. Parents of the children receiving GCBT participated in adjunctive psycho-education sessions and the effect of these sessions on parental anxiety was also evaluated. METHODS: Participants were 12 children, six male and six female, aged between 11 and 15 years who were attending a child mental health service. Participants were interviewed with their parents and anxiety symptoms assessed, using the following measures: Anxiety Disorder Interview Schedule - revised, the Children's Depression Inventory, the Revised Children's Manifest Anxiety Scale, the Coopersmith Self-Esteem Inventory and the Child Behaviour Checklist. Parental anxiety levels were assessed using the Depression, Anxiety and Stress Scale. The 12 children were randomly assigned into two age- and sex-matched groups. While the first group received therapy, the second group acted as a treatment-as-usual control (TAU) group. The second group began group cognitive behavioural therapy after the 10-week waiting period. All participants and their parents provided structured feedback on the intervention. RESULTS: Group cognitive behavioural therapy was significantly effective in reducing both child-reported depressive symptoms, and anxiety on the physiological, worry and total anxiety subscales of the Revised Children's Manifest Anxiety Scale. There were associated significant increases in the childrens' subjective levels of general and total self-esteem, that relating to their self-confidence with peers and when engaging in social and academic pursuits. Diagnosis of anxiety disorder reduced by an average of 67% immediately post-treatment, and by 72% by the onemonth follow-up period. Parents reported significant reductions in their children's levels of internalising symptoms, thought and attention problems. However, parents reported no significantly positive changes in their own levels of depression, anxiety and stress symptoms. CONCLUSIONS: Group cognitive-behavioural therapy is a useful and clinically effective intervention for the treatment of anxiety disorder in children. PMID- 30290498 TI - The validity of a latent class typology of adolescent drinking patterns. AB - OBJECTIVES: This study examined the validity of a latent class typology of adolescent drinking based on four alcohol dimensions; frequency of drinking, quantity consumed, frequency of binge drinking and the number of alcohol related problems encountered. METHOD: Data used were from the 1970 British Cohort Study 16-year-old follow-up. Partial or complete responses to the selected alcohol measures were provided by 6,516 cohort members. The data were collected via a series of postal questionnaires. RESULTS: A five class LCA typology was constructed. Around 12% of the sample were classified as 'hazardous drinkers' reporting frequent drinking, high levels of alcohol consumed, frequent binge drinking and multiple alcohol related problems. Multinomial logistic regression, with multiple imputation for missing data, was used to assess the covariates of adolescent drinking patterns. Hazardous drinking was associated with being white, being male, having heavy drinking parents (in particular fathers), smoking, illicit drug use, and minor and violent offending behaviour. Non-significant associations were found between drinking patterns and general mental health and attention deficient disorder. CONCLUSION: The latent class typology exhibited concurrent validity in terms of its ability to distinguish respondents across a number of alcohol and non-alcohol indicators. Notwithstanding a number of limitations, latent class analysis offers an alternative data reduction method for the construction of drinking typologies that addresses known weaknesses inherent in more tradition classification methods. PMID- 30290499 TI - Alcohol dependence and mood state in a population receiving methadone maintenance treatment. AB - OBJECTIVES: The aim of this study was to assess the prevalence of alcohol dependence and anxiety and depressive disorder symptomatology among heroin users in drug treatment. METHOD: Fifty-five clients on methadone maintenance treatment programmes in Dublin were interviewed. RESULTS: Prevalence rates were found to be 56% [n = 31] for alcohol dependence, 56% [n = 31] for anxiety disorder symptomatology, and 42% [n = 23] for depressive disorder symptomatology. This finding of comorbid alcohol dependence and psychopathology among methadone maintenance treatment clients suggests that both clients' health and methadone maintenance treatment participation and completion rates may be compromised. CONCLUSIONS: Alcohol dependence and psychopathology among methadone maintenance treatment clients should be considered when providing effectively targeted services to the drug using population. PMID- 30290500 TI - Effectiveness of daily outpatient alcohol detoxification by an Irish public psychiatric hospital - A pilot study. AB - OBJECTIVE: To assess the effectiveness of daily outpatient alcohol detoxification in an Irish public psychiatric hospital. METHOD: The outpatient records of patients presenting to the Assessment Unit of St Brendan's Hospital in one year (August 2004-July 2005) with symptoms of Alcohol Dependence Syndrome (ADS) and commencing daily outpatient detoxification were examined retrospectively for parameters relevant to the objectives of the study. The results were compiled and analysed using descriptive statistics. RESULTS: Forty patients underwent outpatient alcohol detoxification in one year and complete records were available for 32 patients (80%). Twenty patients had fixed addresses in the hospital catchment areas, eight patients had no fixed addresses and the remaining four patients had addresses outside the catchment areas. Seven patients (22%) presented with a co-morbid psychiatric condition including depression (four patients), anxiety disorder (two patients) and personality disorder (one patient). All seven patients were known to psychiatric sector services. Of the 32 patients commencing detoxification, 28 patients (87.5%) attended on the second day whilst 22 patients (69%) attended their third day's appointment. Only 17 patients (53%) completed the outpatient detoxification. Thirteen patients (40.6%) received at least two outpatient detoxifications during the year; of whom seven patients (58%) received their second detoxification within two months of the first one. The record of 20 patients (62.5%) showed that they had received advice regarding selfreferral to counselling services. CONCLUSION: A high proportion of patients (47%) presenting with symptoms of ADS did not complete daily outpatient detoxifications. A high proportion of all patients (40.6%) also underwent multiple outpatient detoxifications during the year. It is possible that the separation between alcohol detoxification and alcohol counselling services in Ireland contributed to these disappointing results. PMID- 30290501 TI - Does psychoeducation influence carers' attitudes to treatment of schizophrenia? AB - OBJECTIVE: To measure the impact of a six-week Carer Psychoeducation Program (CPP) on factors that influence attitudes towards treatment among carers and relatives of people suffering from schizophrenia. We also examined which specific attitudes to treatment the CPP had the most effect on. METHOD: Between 2002 and 2004, all patients and their relatives continued standard care. During this period, we conducted a historically-controlled open trial, in which 64 relatives completed a 17-item adapted version of the Drug Attitudes Inventory (DAI) before and after the CPP. RESULTS: Attitudes to treatment improved significantly overall (p < 0.001), an improvement most marked in terms of attitudes to health and illness, attitudes towards the physician and attitudes towards the potentially harmful effects of treatment. No statistically significant improvement was found, however, in attitudes to locus of control or the preventative role of treatment. CONCLUSION: A CPP specifically improves family attitudes towards treatment. This finding is clinically important because such attitudes influence adherence which, in turn, influences outcome. The fact that certain attitudes are influenced by the CPP, while others are not, may help to explain the mechanism through which patient outcomes improve. PMID- 30290502 TI - International human rights law and mental illness. AB - The Irish State has been party to a collection of international treaties and declarations that directly affect the care of those who suffer from mental disorders. These documents set up what are considered as minimum core standards that outline the standard of care that should be provided as a basic human right. This article reviews the relevant sections of these documents and reflects as to how they have been applied in Ireland. International conventions, which have the status of a treaty, are monitored and interpreted by various commissions and committees. This article draws on the comments of these bodies as to how a state should provide for those with mental illness. Areas such as the rights of children who are mentally ill and those who are detained by the state are examined in detail. Other areas covered are the right to the highest attainable level of mental health care, the right not to be subjected to a clinical trial, equal access to mental health care, and the right to be safeguarded against unjust involuntary detention.

PMID- 30290507 TI - Violence and aggression in the Drug Treatment Centre Board. AB - OBJECTIVES: We sought to determine the prevalence of and the factors associated with violent and aggressive incidents among clients attending an out-patient methadone stabilisation and detoxification programme in Dublin. METHODS: We retrospectively examined all incident report forms over a two-year period. We also obtained information on demographics, main drug of abuse, timing and location of the incident as well as psychiatric and physical comorbidity among the perpetrators from case note review. RESULTS: Two hundred and ninety-five incidents occurred over the study period. The overall rate of violence and aggression was 85 per 1,000 clients attending the centre per year. Most incidents involved verbal abuse. Females were significantly more likely to be involved in assaults compared to males. A high proportion of clients (80%) who were physically aggressive tested positive for benzodiazepine medication. CONCLUSIONS: Levels of recorded violence have remained stable however racial abuse has increased in recent years. The relatively low overall rate of violence suggests that existing measures have helped reduce the number of aggressive and violent incidents in the centre. Most of the victims were either doctors, nursing staff or general assistants. This finding reflected their respective roles in the centre, which included limit setting and dealing with positive drug screens among clients. PMID- 30290508 TI - The assessment of need in patients presenting to psychiatrists in the general hospital. AB - OBJECTIVE: The evaluation of psychosocial need is an important part of the assessment of any patient who presents to a psychiatrist. The Camberwell Assessment of Need (CAN) instrument was developed for the systematic assessment of need in people with severe and enduring mental illness. Variations of the CAN have been developed for forensic, elderly and learning disability populations. Patients presenting to psychiatrists in the general hospital may also have different needs to those presenting to psychiatrists in other settings. We set out to examine whether the CAN would be useful in identifying needs in patients referred to psychiatrists in the general hospital with self-harm or alcohol problems. METHOD: Over a four-month period from September 2004 we prospectively assessed all patients with self-harm or alcohol problems referred to a liaison psychiatry service. We used the short version of the Camberwell Assessment of Need instrument (CANSAS) to assess psychosocial needs. Urgent referrals to a local psychiatric service of patients with severe enduring mental illness (SEMI) were assessed using identical methodology over the same time period and used as a comparison group. RESULTS: Over the study period 53 patients with self-harm, 42 with alcohol problems and 45 with SEMI were assessed. Patients presenting with self-harm and alcohol problems had significantly fewer needs than those with SEMI (4.40 vs 3.98 vs 7.96, p < 0.001). Looking after the home, self-care, daytime activity, psychotic symptoms, safety to others and sexual expression needs were significantly greater in the SEMI group than in either the DSH or alcohol groups. Only safety to self-needs in the DSH group and alcohol needs in the alcohol group were significantly higher than in the SEMI group. The proportion of needs that were unmet was similar in each group. CONCLUSIONS: The CANSAS instrument identified some needs in deliberate self-harm and alcohol problem patients that might not have been identified during the course of a standard psychosocial assessment. It was easy to administer and as such was a useful addition to the assessment process. However the development of a more specific instrument for the assessment of need in these populations would be useful. PMID- 30290509 TI - Detection, assessment and management of eating disorders; how involved are GPs? AB - OBJECTIVES: To determine the extent to which general practitioners are currently active in the screening, assessment, diagnosis and management of eating disorders. To identify current deficits in service delivery for eating disordered patients, as identified by general practitioners. METHOD: A postal questionnaire was circulated to 360 general practitioners within the greater Dublin area and North Eastern Health Service Executive. RESULTS: Response rate was 25%. Respondents had lower case-loads of eating disordered patients than would be expected given the epidemiology of anorexia and bulimia nervosa. Most do not routinely screen for eating disorders, even in at-risk populations and are unaware of the current evidence-based data for guidance. GPs do not feel confident at managing eating disorders within the primary care setting and see their chief role as that of referral to psychiatric services. Treatment outcomes are typically poor. Concern was expressed at the lack of access to specialist treatment in the public sector. Specific deficits in service provision were highlighted including delays in assessment, lack of services appropriate to the adolescent population, poor service transition, and poor availability of psychotherapy at primary care level. CONCLUSIONS: Eating disorders are currently underdiagnosed in the primary care setting. Use of simple screening tools might aid detection of pathological eating patterns, particularly in at-risk groups. General practitioners feel under-equipped to manage these complex disorders, given that the resources required to provide high quality care are not widely available. Better integration of primary and secondary services, coupled with training for GPs in the area of screening, assessment and diagnosis, may lead to earlier intervention and improved outcomes. PMID- 30290510 TI - Atypical antipsychotic monitoring: A survey of patient knowledge and experience. AB - OBJECTIVES: To examine the knowledge and experiences of side-effects and their monitoring in patients prescribed atypical antipsychotic medications. METHODS: A tick box survey was designed to ask questions of patients prescribed atypical antipsychotic medications about side-effects and monitoring for them. This survey was distributed anonymously to all suitable outpatient attendees over a three month period who had been prescribed atypical antipsychotic medication for at least one year. RESULTS: Seventy-four of the 90 surveys (82%) distributed were returned complete. Fifty-six (76%) of those surveyed said they were currently experiencing side-effects. Twenty-two (39%) said they had not told their psychiatrist about the side-effects. Weight gain was most commonly complained of (49%). Forty-five (61%) said that they had had no monitoring blood tests in the past year. Fifty-one (69%) did not know that certain monitoring blood tests were recommended. CONCLUSIONS: Patients prescribed atypical antipsychotic medications are not currently being monitored as best practice dictates. It cannot be assumed that GPs will pursue this monitoring. More resources are needed for mental health services so that adequate monitoring services can be provided. PMID- 30290511 TI - Tackling a long waiting list in a child and adolescent mental health service. AB - OBJECTIVE: Long waiting lists have a negative impact on client satisfaction, staff moral and referrer's opinion of the service. The aim of this project was to decrease a waiting list from a maximum wait of more than one year to a wait of no more than six weeks. METHOD: We introduced three simultaneous initiatives to decrease a long waiting list; (i) an individually led triage system (ii) setting up an attention deficit hyperactivity disorder (ADHD) specialist team and (iii) division of the residual waiting list between team members. These initiatives were introduced and analysed over a ten month period. The study period ran from 1/3/2004 to 31/12/2004. RESULTS: The waiting time to first appointment was significantly reduced. At the beginning of the study there were 62 people waiting to be seen and each had waited an average of 122 days with a waiting time range of 0-449 days. At the end of the study, there were 19 people waiting with a mean waiting time of 19 days and a range of 0-168 days. CONCLUSIONS: The single most powerful intervention was the triage system. The ADHD clinic allowed referrals to be streamlined in a very structured and efficient way. The division of the residual waiting list was not as onerous as it first appeared. The service saw more referrals then ever during the study period. Referrers and families appreciated being seen more quickly. By removing the burden of the waiting list from staff the potential for creative thinking around further development of the service increased. PMID- 30290512 TI - Survey of a second opinion clinic in child and adolescent psychiatry. AB - OBJECTIVES: Second opinion is a medical opinion provided by a second physician/ medical expert after first receiving an opinion by another physician/ medical expert. Little is known about the provision of second opinion in Child and Adolescent Mental Health Services (CAMHS). This study describes the second opinion service provided by the Child and Adolescent Mental Health Services (CAMHS) in the South Wales region. METHODS: We undertook a survey of a second opinion service in Child and Adolescent Mental Health Services (CAMHS). We also assessed whether the recommendations made by the second opinion clinic were implemented by the referrers. RESULTS: The diagnoses were not changed in 68% of the cases but alternative treatments were suggested. In 90% of the cases the treatment recommended by the clinic was implemented and nearly 70% of the patients showed improvement with the recommended treatment. CONCLUSION: A second opinion service can provide valuable support and expertise to CAMHS and the referred families.

AB - Early intervention in depression is important for many reasons including expeditious alleviation of suffering, assisting parenthood, suicide prevention and helping the economy. The fact that people with depression frequently employ maladaptive coping strategies, notably alcohol misuse, suggests the need for evidence-based self-help for sufferers. Self-help can be viewed as a philosophy of patient empowerment and as "a health technology solution to volume and demand". Bibliotherapy (self-help using written materials) provides information and encourages the reader to make changes leading to improved self-management. Enthusiasm for the use of bibliotherapy in depression should be tempered by pursuit of a sound evidence base. PMID- 30290514 TI - Olanzapine-induced rhabdomyolysis. AB - We present a case of possible olanzapine-induced rhabdomyolysis in the absence of other features of neuroleptic malignant syndrome (NMS). There is evidence to suggest that there are different underlying pathophysiological mechanisms for rhabdomyolysis occurring alone, in contrast to when it presents as part of NMS. This has possible implications for drug rechallenge which is discussed. PMID- 30290515 TI - Duloxetine-mirtazapine combination in depressive illness: The case for Limerick 'rocket fuel'. AB - The use of complex psychopharmacological regimens is increasingly advocated in more difficult to treat depressive illness. The combination of venlafaxine with mirtazapine - 'California rocket fuel' is one such example involving an SNRI combined with a NaSSA. We describe two cases that highlight the potential usefulness of duloxetine used in combination with mirtazapine that also emphasise the danger of drug-induced hypomanic switching. This combination may have a specific role for carefully selected patients but caution is needed given the potential to induce profound alterations in mental state.

AB - Abstrsct A case is described in which a man with chronic pain syndrome (CPS) presented to a city General hospital in suicidal crisis after referral from a provincial psychiatric unit, having taken an overdose of a variety of medications, precipitated by the absence of his opioid (Oxycontin) analgesia which he had been abusing intra-nasally. This is to our knowledge the first reported case in Europe of drug diversion from oral to intranasal use of Oxycontin, a controlled-release preparation of the synthetic opiate, oxycodone hydrochloride. There is also a dearth of reference to the abuse potential of this agent in the European literature. As sufferers from chronic pain syndrome increase in number, and opiate prescription rates worldwide are maintained, this case highlights the potential of opiate abuse or dependence and drug diversion emerging as a significant medical problem in CPS patients in Europe.

PMID- 30290523 TI - Empowerment, quality of life and service satisfaction: comparisons between a hospital and community placement group. AB - OBJECTIVES: Recent advances in mental healthcare policy and service delivery have lead to the development of community care initiatives which have enabled those individuals traditionally cared for in hospital environments to be resettled successfully in community living arrangements that foster an ethos of empowerment and recovery. This study sought to identify differences between a hospital continuing care group (n = 16) and a community placement group (n = 20) in relation to quality of life, satisfaction and levels of empowerment. METHOD: The study was a cross-sectional design. It follows up a cohort of individuals identified as the 'hospital continuing care group' (365+ consecutive days in psychiatric hospital care) by Homefirst Community Trust in Northern Ireland. A proportion of this population has been resettled into community care environments and some continue to reside in hospital. Patients both in the hospital continuing care group and the community placement group completed two standard questionnaires that covered a number of variables including empowerment, quality of life and service satisfaction. RESULTS: There were significant differences between the hospital continuing care and community placement groups across scores on service satisfaction, quality of life, and empowerment in the current study. Hypotheses relating to service satisfaction (z = -4.117; p < 0.01 ), quality of life (z = -3.944; p < 0.01) and empowerment (z = -4.645; p < 0.01) were supported with higher levels of each evidenced by the community placement group. CONCLUSIONS: The results are supportive of continued resettlement from continuing care in traditional psychiatric hospitals and suggests that such resettlement increases quality of life, satisfaction with services and levels of empowerment. The limitations of the research design are empowerment. The limitations of the research design are also discussed. PMID- 30290524 TI - Opiate-dependent adolescents in Ireland: a descriptive study at treatment entry. AB - OBJECTIVES: To describe the drug history and co-existing psycho-social problems among under-19 year olds accessing treatment for opiate dependency, including methadone maintenance, and examine for any gender differences. METHOD: A descriptive study of under-19 years assessed at the largest drug treatment clinic in Dublin, Ireland, between October 2000 and September 2006. Data was obtained through review of case notes, assessment questionnaires and urine drug screens. RESULTS: Eighty-six young people were included. Their mean age was 16.8 years. Forty-six (54%) were female. Only 26 (30%) reported an intact family of origin. Twenty-three (27%) had been in care. Mean age for first use of any illicit drug was 12.4 years, and for heroin was 14.8 years. The mean age of leaving school was 14.4 years; 42 (49%) first tried heroin after leaving school. Forty-one (48%) had a history of homelessness. Forty-four (51%) had previously injected; 26 (30%) were currently injecting. Fifty-six (65%) had not been screened for blood-borne diseases; twenty-one (24%) subsequently tested positive for hepatitis C. Thirty eight (48%) had previous convictions; 33 (38%) were facing charges. Forty-five (52%) had previously seen a psychiatrist; nine (11%) had received inpatient psychiatric treatment. Boys were more likely to leave school early, have a substance-abusing sibling, and to have a past conviction. Girls were more likely to have a partner, and have taken a deliberate overdose. CONCLUSIONS: This study highlights the multiple and complex needs of teenagers abusing opiates. Services seeking to meet their needs will require a broad range of interventions and excellent interagency co-operation. PMID- 30290525 TI - Male secondary school student's attitudes towards using mental health services. AB - OBJECTIVES: The rate of suicide among young men is rising. However, young men are reluctant to use mental health services. In this study we explored young men's attitudes towards mental illness and mental health services, as well as their willingness to use these services. METHODS: Four focus groups were conducted in two Dublin schools. A total of 18 students participated in the study. RESULTS: Students held negative views towards mental health services, particularly in respect to psychiatric hospitals and medication. Students were not well informed about whom to contact if they had depression and were very conscious about the stigma of going to see a 'professional'. Many students did not recognise depression as being a mental illness and could not differentiate between depression and feeling sad. CONCLUSIONS: This study shows that a lack of knowledge and understanding about mental illness, combined with prejudice against mental health professionals and fear of stigma, are important barriers to access of mental health services for young men. PMID- 30290526 TI - A survey of old age psychiatry consultation/liaison services in Ireland. AB - OBJECTIVES: The aim of this survey was to assess current structures for provision of consultation/liaison services to older people in the Republic of Ireland, and to ascertain the proportion of referrals to psychiatry of old age arising from consultation/liaison referrals. METHODS: A postal questionnaire was sent to the 19 public sector, old age psychiatry services, operating in 2005. Information was obtained from 15 of these 19 services regarding the referrals they received in 2005. FINDINGS: Consultation/liaison referrals make up 36% of total referrals to psychiatry of old age services. Two of 14 services had ring-fenced resources for consultation/liaison work. Three of 14 consultants described their service as having a significant liaison component. Location of the service and the criteria for accepting a referral are associated with the proportion of referrals that are consultation/liaison. CONCLUSIONS: Consultation/liaison referrals make up a significant proportion of referrals. To provide an effective consultation/liaison service ring-fenced resources are required. Despite this recent long term strategies for national service development have neglected this area. PMID- 30290527 TI - Clarithromycin induced mania.

AB - OBJECTIVES: This study examined the impact of psychiatric teaching on attitudes toward psychiatry of a cohort of medical students by means of a questionnaire survey. The impact of social desirability bias on questionnaire responses was also explored. Gender and nationality subgroups in the cohort were examined in more detail to determine whether these variables had any bearing on attitude change. METHODS: Fifth year medical students at NUI Galway completed the Attitudes to Psychiatry-30 questionnaire at the beginning and end of the psychiatric curriculum. This was coupled to the Marlowe-Crowne Social Desirability Scale (13 items) to determine the effect of this potential bias on responses to the attitudinal scale. Anonymity was ensured by using unique identification codes on the questionnaires, which facilitated individual comparisons of pre- and post-teaching responses. RESULTS: Attitudes toward psychiatry were positive prior to training but significantly improved following the teaching programme. There was no difference in attitudinal change between male and female subgroups. While students from outside the EU did show an improvement in mean scores on the ATP-30 this increase failed to reach significance. This finding was in contrast to the results for students from EU states whose mean increase on the ATP-30 was highly significant. Social desirability questionnaire scores fell significantly between the first and second administration, lending support to the findings being a true reflection of the students' attitudes toward psychiatry. CONCLUSIONS: These findings suggest that a teaching programme has the ability to influence students' attitudes. This is encouraging for recruitment into psychiatry and overall patient care. PMID- 30290530 TI - The Gloucester assertive community treatment team: A description and comparison with other services. AB - : Assertive Community Treatment (ACT) has developed globally as a model of community care for the severely mentally ill. However, in the United Kingdom there is mixed evidence regarding improvements in outcome and concerns about ACT teams having poor fidelity to the original ACT model. OBJECTIVE: This study presents the fidelity characteristics of an established ACT team serving Gloucester City. It describes service user demographic and illness data and compares these findings to other important studies in the United Kingdom. METHOD: The Dartmouth Assertive Community Treatment Scale was applied to rate the Gloucester ACT team's fidelity characteristics. The Gloucester Caseload Project Demographic Pro-Forma was collected from all of the team's 79 service users. RESULTS: The population of severely mentally ill ACT service users in Gloucester City were an older and more "disabled" group compared to the classic ACT studies. Furthermore, although findings indicate a high level of fidelity to the original ACT model, the team it is still associated with high levels of inpatient treatment. CONCLUSION: High fidelity ACT services appear to be associated with high admission rates. Therefore teams should not be viewed as alternatives to hospital admission but have goals of improving engagement and social functioning. Furthermore, findings have allowed the team to benchmark its service and target areas for further service development. More consistent reporting of fidelity data on ACT research would facilitate comparison across different services. PMID- 30290531 TI - Views of family carers to the future accommodation and support needs of their relatives with intellectual disabilities. AB - OBJECTIVES: The demand for places in supported accommodation is likely to rise due to the increasing longevity of people with intellectual disabilities and as their parents become unavailable or unable to care for them. However few attempts have been made to ascertain carer's views on alternative accommodation. METHOD: Four studies were undertaken in Northern Ireland to ascertain carer's views using three different methods. In all, 387 carers participated with the response being greatest for individual interviews conducted in the family home and least for self-completed questionnaires and attendance at group meetings. RESULTS: The majority of carers envisaged the person continuing to be cared for within the family. The most commonly chosen out-of-home provision was in residential or nursing homes, living with support in a house of their own and in homes for small groups of people. Few carers chose living with another family. However only small numbers of carers envisaged alternative provision being needed in the next two years and few had made any plans for alternative living arrangements. CONCLUSIONS: The implications for service planning are noted, primarily the need for individual reviews of future needs through person-centred planning; improved information to carers about various residential options and their differential benefits, along with more services aimed at improving the quality of life of people living with family carers. These need to be underpinned by a commitment of statutory agencies to partnership working with family carers. The implications for mental health services are noted. PMID- 30290532 TI - Older people with enduring or recurrent severe mental illness in the Eastern Region of Ireland. AB - OBJECTIVES: There has been no specific planning for older people with enduring or recurrent severe mental illness in Ireland. This survey aims to identify the number of affected over 65 year olds (graduates) and 55-64 year olds (prospective graduates) in the Health Service Executive, Eastern Region, their diagnoses and their use of psychiatric services. METHOD: A comprehensive survey of the ten general adult psychiatry and four old age psychiatry services in the (HSE) Eastern Region was undertaken for the year 2003 to determine the number of patients, their diagnoses and service utilisation. RESULTS: 649 people over 65 years old were identified within the general adult psychiatry services and a further 279 within the old age psychiatry services giving a total of 928. (This number rose to 1141 after correcting for missing outpatient data.) 1,397 people between the ages of 55-64 were identified. (This number rose to 1,916 after correcting for missing outpatient data.) Conclusions: There are substantial numbers of 'graduates' and 'prospective graduates' in the Eastern Region. It is essential that services for this population are specifically planned for and further qualitative research is required to inform this process. PMID- 30290533 TI - Older people with enduring or recurrent severe mental illness (graduates): A literature review. AB - OBJECTIVES: To review the literature on older people with enduring or recurrent severe mental illness with an onset earlier than 65 years (graduates) and, in particular, to look at the specific features and needs of this group. METHOD: A Medline literature search produced 41 relevant papers and reports on the subject. RESULTS: There are a substantial number of older people with severe mental illness and the number will rise in line with increased longevity. As they age these patients' psychiatric disabilities are compounded by medical and social problems. The move to community based care has largely ignored the needs of graduates who were previously cared for in psychiatric institutions. CONCLUSION: There is an urgent need to plan and develop adequate services for this vulnerable group. PMID- 30290534 TI - Anorexia nervosa or otherwise? The usefulness of adult diagnostic systems in child and adolescent eating disorders. AB - We report on the case of a 15-year-old boy referred to Warrenstown inpatient unit for management of what appeared to be a typical case of anorexia nervosa. Over the course of his admission however, this diagnosis was no longer considered appropriate and substituted for a food avoidance emotional disorder. This is one of a number of cases of young males who have recently been referred for inpatient management of anorexia nervosa but which emerged into something quite atypical. The limited usefulness of the ICD-10/DSM-IV criteria in the diagnosis of an eating disorder in childhood and adolescence in this case reflects a broader level of discontent with the application of such diagnostic classification systems in a paediatric population.

PMID- 30290539 TI - First admissions to inpatient care in Ireland for schizophrenia 1971-2004: trends in gender and age. AB - : First admissions for schizophrenia to inpatient psychiatric services in Ireland are declining. The reason for this decline has been debated and it has been proposed that it could be attributable to either a decline in incidence or to policy changes or to both. OBJECTIVES: This study examines the trends in first admission numbers for schizophrenia in Ireland and the influence of gender and marital status on age at first admission over the time period 1971-2004. METHOD: Data were derived from the National Psychiatric Inpatient Recording System (NPIRS) for the years 1971-2004 inclusive. All first admissions with a diagnosis of schizophrenia during these years were included in the analysis. RESULTS: The results showed a significant decline in the number of first admissions with the number of first admissions for males exceeding those for females. The average age of first admission was higher for females than males (p < 0.001). The average age of first admission showed a decline for males (p < 0.001), but not for females. Marital status was a stronger predictor of age of admission than gender (p < 0.001). Never married persons had a lower age of first admission than those married and the delaying effect of marriage on age at first admission was evident in males and females (p < 0.001). CONCLUSIONS: An examination of first admission hospital data confirm male disadvantage in schizophrenia. The study highlighted a number of areas for future research which include examining gender differences in more refined diagnostic sub groups of schizophrenia and the monitoring of first contacts with community-based mental health services. PMID- 30290540 TI - Psychological health and well-being among young Irish adults. AB - OBJECTIVES: The aim of this study was to examine and describe levels of psychological health and well-being in a group of young people living in Dublin. METHOD: A sample of 97 young people (50 males, 47 females) were assessed for psychological status, suicidal ideation, substance misuse, contact with the law, self-esteem and locus of control as well as various social indicators such as educational attainment and social connectedness. A screening version of the Structured Clinical Interview for DSM-IV Axis Diagnosis (SCID) was used to assess psychological functioning and the Beck Scale for Suicide Ideation was employed to ascertain suicidal ideation. Self-esteem was measured using the Rosenberg Self Esteem Scale and locus of control was measured using a scale devised by Pearlin, Menaghan, Lieberman and Mullan (1981). RESULTS: Symptom levels were high and approximately one fifth of respondents had a probable psychiatric condition (most commonly depression or anxiety). Yet, only a small percentage was receiving treatment for psychiatric difficulties. Over half of the participants had used nonprescription drugs at some time. Alcohol consumption was high, especially amongst male respondents. Over half of those interviewed were categorised as misusing alcohol and/or drugs and participants greatly underestimated their level of alcohol use. Approximately one-quarter had had some contact with the law which was related to deficits in educational attainment and the latter variable was associated with childhood economic disadvantage. CONCLUSIONS: These findings suggest that among a sample of 97 young Irish people, a high level of psychiatric symptomatology and excessive use of alcohol is evident. This remains largely untreated as only a small percentage of the group had sought help for psychological difficulties which suggests a need to address the issues of mental health awareness, alcohol use and the accessibility of services. The paper also underlines the association between economic disadvantage and lack of educational attainment with associated linkages to offending. PMID- 30290541 TI - Toxic psychosis? Duration of untreated psychosis, symptomatology and cognitive deterioration in first episode psychosis. AB - OBJECTIVES: To examine the relationship between cognitive deficits, the duration of untreated psychosis (DUP) and positive and negative symptoms in a first episode psychosis sample. METHOD: We assessed a consecutive sample of first episode psychosis participants from a catchment area service with a comprehensive neuropsychology battery, a family and service-user based measure of DUP and measures of symptomatology. RESULTS: Using correlations and stepwise linear regressions, we found strong relationships between measures of DUP and positive symptomatology. We found that positive and negative symptoms were associated with different time periods within DUP. However, we did not find evidence of a relationship between DUP and cognitive factors. CONCLUSIONS: There was no evidence of a relationship between DUP and cognitive deterioration. However, there does appear to be evidence of a relationship between positive symptoms and aspects of DUP. These results highlight the importance of the heterogeneity of DUP and the potential to reduce positive symptoms through early intervention.

PMID- 30290543 TI - Depression and cardiovascular disease: does antidepressant treatment improve cardiac outcome? AB - OBJECTIVE: The association between depression and cardiovascular disease has been well documented but the nature of this relationship continues to be defined. Given the accumulation of epidemiological evidence linking these diseases a number of interventional studies have been undertaken to assess the issue of whether antidepressant treatment in depressed patients with cardiovascular disease improves cardiac outcome. The objective of this paper is to review recent randomised controlled trials on this topic and to explore the implications that these may have for future research in this area. METHOD: This review is derived from a MEDLINE search using the search terms 'depressive disorder' and 'cardiovascular diseases'. Only randomised controlled trials published in English with clearly defined methods and interventions are included here. Reference sections from the articles were used to identify additional relevant studies. RESULTS: A small number of high quality trials were uncovered which indicated mixed results in terms of the treatment of depression in cardiovascular disease. None indicated a statistically significant difference in cardiac outcome. CONCLUSIONS: It is not possible at this time to recommend treatment for depression to reduce cardiovascular risk. However depression remains prevalent in patients with cardiovascular disease and is a treatable cause of morbidity in its own right.

AB - The full implementation of the Irish Mental Health Act 2001 brings about the introduction of an altered legal definition of mental disorder, mandatory review of involuntary detention within a 21-day period and new statutory rules regarding the use of seclusion and mechanical means of bodily restraint. This legislation came into full effect on November 1, 2006. The implications of this for the intellectual disability psychiatry sector are profound and the full ramifications of these changes will only become fully apparent over time. This also occurs at a time when we are facing unprecedented developments in government mental health policy, major changes to postgraduate training in psychiatry, difficulty recruiting appropriately skilled staff and increasing legal requirements on employers to ensure staff safety. Several of these drivers for change may appear at face value to be in conflict and a complex balance will be required if these changes are to be blended to ultimately improve the care provided to clients of our services. PMID- 30290550 TI - Determinants of duration of untreated psychosis in an Irish catchment area sample. AB - OBJECTIVE: To examine the variables that influence of duration of untreated psychosis (DUP) prior to presentation in persons with a first episode of psychosis. METHOD: Prospective examination of consecutive first presentations with DSM-IV psychosis attending a community based psychiatric service. RESULTS: One hundred and seventy-one patients had an average duration of untreated psychosis of 18 months and a median of five months. The mean duration of untreated mania was 1.5 months, median 0.75 months. DUP was predicted by social withdrawal and diagnosis in the total group and by prodrome in the schizophrenia/schizophreniform group. DUP was not associated with age at onset of psychosis, educational years or living status. CONCLUSIONS: There are significant differences in DUP between diagnostic groups. Increased social withdrawal is associated with a longer DUP. PMID- 30290551 TI - High prevalence of risk factors for physical illness in a long-stay psychiatric unit. AB - OBJECTIVE: The aim of this study was to determine the prevalence of risk factors for physical illness in a long stay psychiatric unit, where all care (both psychiatric and physical) is provided by the psychiatric team. METHOD: All patients in the long-stay ward had a full physical examination including calculation of BMI. All patients had blood sampling including FBC, U&E, LFTs, TFTs, lipid profile (total cholesterol, triglycerides, HDL and LDL), glucose, HbA1c, and prolactin. ATP111 criteria were used to determine the presence of the metabolic syndrome. RESULTS: We found the mean number of comorbid medical diagnosis was 2.7. The prevalence of metabolic syndrome was 40.7% (44.4% of females and 24.1% of males). The prevalence of obesity was 51%, and 51% also had a total cholesterols in excess of 5.0mmol/l. Prolactin was elevated in two-thirds of female patients. CONCLUSION: We conclude that the annual physical examination is of limited value in long-stay psychiatric unit. The high prevalence of physical illness and physical risk factors warrants primary care involvement in screening and treatment of long-stay psychiatric patients. PMID- 30290552 TI - Point prevalence of diabetes, obesity, hyperlipidaemia, hypertension and smoking in outpatients on clozapine. AB - OBJECTIVES: Patients with schizophrenia are known to be at higher risk than the general population of cardiovascular disease. Clozapine has been associated in the literature with high levels of cardiovascular risk factors such as weight gain, diabetes, hyperlipidaemia and hypertension. We set out to determine the prevalence of these risk factors in a population of Irish psychiatric patients. METHOD: In February 2006 we measured body mass index, fasting blood glucose, haemoglobin A1c (HbA1c), lipid levels, mean blood pressure and smoking rates among all outpatients prescribed clozapine attending an urban, community based mental health service. RESULTS: There were 50 outpatients (33 male; 17 female) on clozapine and they had been taking it for a mean of 5.4 years (mean daily dose 428.8mg). The mean body mass index was 28.3. Patients had gained a mean of 8kg since commencing clozapine. One patient had been diagnosed with diabetes. Of the other 49 none met diagnostic criteria for diabetes. The mean fasting blood glucose was 5.5mmol/l and the mean HbA1c was 5.7%. One patient was on treatment for hyperlipidaemia. The mean fasting cholesterol among the other 49 patients was 5.4mmol/l, while the mean fasting triglycerides was 2.1 mmol/l. Thirty (61.2%) had a fasting cholesterol greater than 5.0mmol/l, while 18 (36.7%) had triglycerides of greater than 2.0mmol/l. Three patients were on treatment for hypertension. Thirty-six of the 50 (72%) smoked (mean 13 cigarettes per day). CONCLUSIONS: The prevalence of obesity, diabetes, hyperlipidaemia and hypertension in this population was high but lower than might have been expected from US studies. It is important that cardiovascular risk factors are closely monitored and actively addressed in this at risk population. PMID- 30290554 TI - Suicide and the reluctance of young men to use mental health services. AB - Young men are grossly over represented in Irish suicide statistics, yet this group is the least likely to use mental health services. This paper outlines why young men are reluctant to access mental health services, framing the problem in the context of risk factors for suicide such as binge drinking and social change. The paper argues that de-stigmatising mental illness and encouraging young men to seek help for emotional problems should be a priority for policymakers. PMID- 30290553 TI - The homeless mentally ill - an audit from an inner city hospital. AB - OBJECTIVE: To determine the proportion of those that are homeless attending the Mater Misericordiae Hospital's (MUH) psychiatric service, including those presenting to accident and emergency who were homeless, and to compare the homeless group with the non-homeless so as to obtain a profile of this group. METHODS: All adults over 16, referred for psychiatric assessment, attending A&E were included, as were those attending outpatient clinics, liaison consultations and inpatients in the psychiatric unit, in the six-month period from January to June 2003. Excluded were those who were under 16, who refused to participate, who did not speak English, those with a diagnosis of personality disorder and organic brain damage. Questionnaires were completed by psychiatric registrars and a community psychiatric nurse, with an ICD-10 diagnosis recorded on each individual, in consultation with the treating consultant psychiatrist. RESULTS: A total of 628 patients were seen in MUH during the study period, and 13.8% were homeless. Of the homeless, 56.3% were seen as emergency referrals in the A&E, 23% were inpatients (including the psychiatric unit and consultations in medical/surgical wards) and 20.7% were seen in the outpatient department. Of all the A&E referrals to psychiatry, 34.8% were homeless. The homeless presented most commonly in suicidal crisis (26.6%) compared with 12.5% in the non-homeless group. Substance-abuse disorders were the primary diagnosis in 42.3% of the homeless group, accounting for 14.2% in the housed sample. Outcome for both groups was similar, with slightly more homeless being referred for psychiatric admission (17.8%), as compared to 12.0% in the nonhomeless group. CONCLUSIONS: Mental illness and the need for psychiatric services remain a serious issue for a significant segment of the homeless population. The homeless are overrepresented in our accident and emergency department, with their psychological and medical needs not being met in primary care. An integrated multi-disciplinary treatment approach, including outreach work, that addresses their many needs, appears to hold the greatest promise of success in this population. PMID- 30290555 TI - Integrating mental health and primary care services: a challenge for psychiatric training in Ireland. AB - A Vision for Change, the report of the Expert Group on Mental Health Policy asserts as one of its key recommendations the enhancement and formalisation of links between specialist mental health services and primary care. As part of a higher training post in psychiatry a consultation-liaison service was provided by a senior registrar in three rural general practices. This paper describes the experience of this initiative from an educational perspective and discusses the broader implications for Irish psychiatric training. With an emerging emphasis on collaborative mental health care there needs to be an appreciation of the specific set of skills that psychiatry trainees must learn in order to be effective in primary care settings. The tandem development of the appropriate services and training in an Irish context will require dedicated funding and resources. PMID- 30290556 TI - Characteristics of patients admitted to psychiatric intensive care units. AB - OBJECTIVE: A paucity of research exists on the types of patients admitted to psychiatric intensive care units (PICUs), which is important in terms of identifying patient needs, training and service provision. Questions have also been raised as to whether or not ethnic minorities are overrepresented in these units. METHOD: A literature review using MeSH headings from a wealth of databases was performed to identify such studies. In addition studies on ethnic minority overrepresentation in psychiatric care were also identified. RESULTS: Under a dozen studies were identified, mainly from the UK and Australia. Study designs tended to be basic and heterogeneous, but this was reflected in the nature of the study and the data gained. A typical PICU patient emerged, namely a young schizophrenic detained male, belonging to an ethnic minority (if in an inner city), known to mental health services with previous informal, detained and PICU admissions, admitted due to violence and often possessing a forensic history. If a complex need existed, it was usually substance misuse. The inpatient stay tended to be for less than two months and discharge was usually to an acute ward. Ethnic minorities were overrepresented in PICU care. CONCLUSIONS: The literature review highlighted a paucity of good-quality studies in this field. The establishment of a national association of intensive care units as well as national guidelines can only improve services. The reason for ethnic minority over-representation on these units is still far from clear. PMID- 30290557 TI - Psychosis? Beware - case series of clarithromycin and psychosis.

PMID- 30290560 TI - First episode schizophrenia in general practice: a national survey. AB - OBJECTIVE: We sought to establish the views of general practitioners about detecting and managing patients with a first episode of schizophrenia in Ireland. METHOD: Twenty per cent of GPs were invited to participate in a cross-sectional postal survey. RESULTS: Sixty-two per cent (n = 261) participated. Almost all (99.2%) see at least one case of suspected first episode schizophrenia annually. The most commonly (80.7%) encountered symptom is 'bizarre behaviour'. Many (47.7%) rarely or never prescribe antipsychotics to patients whom they suspect have a first episode of schizophrenia. However, 80.6% of GPs reported that they 'always' refer this group of patients to psychiatric services. Over half (57.8%) advised patients with schizophrenia to continue medication for less than a year. A large number of respondents reported that it is difficult to obtain a rapid psychiatric assessment. CONCLUSIONS: GPs want more information about identifying early psychosis, a closer liaison with psychiatric services and a rapid intervention service. PMID- 30290561 TI - Temporal trends in rates of dual diagnoses at a Canadian addictions hospital over a five-year period. AB - OBJECTIVES: Dual diagnosis refers to co-occurring substance use and psychiatric disorders. The principal aims of this investigation were two-fold: 1) to identify aspects of patients' drug use and prior treatment histories associated with their receiving a dual diagnosis upon admission to the Donwood Institute, a residential drug treatment facility located in Toronto, Canada; 2) to track temporal trends in the rates of diagnosed comorbidities over a five-year period at this same institution. METHODS: We conducted an analysis of the intake assessment forms and hospital records of 159 patients who had been admitted to a drug treatment facility during the month of September for each of the years between 1998 and 2002 inclusive. Comparisons were made between patients who had received a psychiatric diagnosis on admission and patients who had received no such diagnosis. We then employed logistic regression analyses to explore the relationship of the variable psychiatric diagnosis on admission to other patient variables. RESULTS: Among the patients studied in our sample, those receiving psychotherapy or taking prescription psychotropic medication at the time of their admission as well as patients whose primary problem substance was cannabis or who had been previously admitted to the treatment facility were significantly more likely to have received a psychiatric diagnosis on admission, in spite of our finding that several patients receiving psychotherapy or taking at least one psychotropic medication did not receive a psychiatric diagnosis on admission. CONCLUSIONS: Whilst our data indicate that psychiatric comorbidity is common among individuals in treatment for substance use disorders at the Donwood Institute, it is possible that some individuals with psychiatric illness in our sample were not diagnosed as such when presenting for treatment of their substance use difficulties. Moreover, temporal tracking of rates of dual diagnoses did not reveal a consistent increase during the period studied. PMID- 30290562 TI - The point-prevalence of alcohol use disorders and binge drinking in an Irish general hospital. AB - OBJECTIVES: There is a paucity of data concerning the prevalence of alcohol use disorders and binge drinking in the general hospital adult population in Ireland. We therefore examined the point-prevalence of alcohol use disorders and of binge drinking in the adult inpatient population of the acute wards of an Irish university teaching hospital. The secondary aim was to examine gender, age, and patient group (medical/surgical) as risk factors. METHOD: We administered the Alcohol Use Disorders Identification Test (AUDIT) to all consenting patients (n = 126) on the acute adult medical and surgical wards over one day. RESULTS: 76% of all inpatients on the acute medical and surgical wards were interviewed (n = 126) using the AUDIT. Of the subjects 28% screened positive for an alcohol use disorder. Of these 91% were identified as binge drinkers. A further 8% of the subjects screened positive for binge drinking but were not identified as having an alcohol use disorder. Overall, 36% of the subjects screened positive for either an alcohol use disorder and/or for binge drinking using the AUDIT. Male gender and under 65s were risk factors for both alcohol use disorders and binge drinking. CONCLUSIONS: The high point-prevalences of alcohol use disorders and binge drinking in hospital inpatients in particular are a cause for concern as they may have illness complicated by or secondary to undiagnosed alcohol excess. As this population is an easily accessible group for screening, and clinical and economic evidence supports intervention, we recommend screening all acute hospital admissions for alcohol use disorders and binge drinking, followed by appropriate management. PMID- 30290563 TI - Telepsychiatry in a Child and Adolescent Psychiatric Service. AB - OBJECTIVES: To carry out a survey on the use of video conferencing equipment by a rural child psychiatric multidisciplinary team and to determine what impact the introduction of this equipment had on service provision. METHOD: Several aspects were studied including user satisfaction and estimations of cost saving, on the basis of avoidance of travel to and from the regional base in Galway. A questionnaire was also developed to determine whether alternative contact would have been made if if this new technology were not in place. RESULTS: The results of the initial six months following commencement were investigated. Use of the equipment was attempted 17 times during this period. Most members of the child psychiatry team participated in its use. Visual problems accounted for 66.7% of reported technical difficulty and 88.9% of users rated their level of satisfaction with the equipment as 'Satisfied' or 'Very Satisfied'. CONCLUSIONS: Apart from the start-up cost implications of installing this equipment, it satisfied its aim of increasing contact between the rural service and St Anne's Children Centre in Galway. The equipment was easy to use and for the most part reliable. PMID- 30290564 TI - Bipolar affective disorder: advances in genetics and mood-stabilising medication.

There is insufficient evidence on which to make firm recommendations about the most effective forms of treatment This is remarkable considering the extent of the problem worldwide, and the importance of dealing with it appropriately in order to prevent further suicides. PMID- 30290566 TI - Music therapy in the treatment and management of mental disorders. AB - OBJECTIVES: An increasing number of research studies support the benefits of providing music therapy in addition to standard treatment for people who have mental disorders. The objective of this paper was to review and summarise recent research findings in relation to this work. METHOD: A review of music therapy studies published since 1994 was undertaken. Criteria for including papers were that they a) were published in English in an indexed, peer-reviewed journal, and b) were conducted as a randomised controlled trial (RCT) or a controlled trial (CT), or c) provided a meta-analysis of existing studies. The large number of papers pertaining to music therapy for older adults who have mental disorders, including Alzheimer's disease and other types of dementia was not included. RESULTS: The findings support a role for music therapy as a structured interaction that patients are able to use to participate successfully, manage some of their symptoms, and express feelings relating to their experiences. Music therapy is demonstrated to be a beneficial intervention for people who have enduring mental illness. Music therapy invites and encourages participation from people of lower functioning levels and employs a non-verbal medium with which people have prior positive associations and in most cases have lifelong experience of using music for self-expression and pleasure. Additionally, the available peer reviewed literature supports the proposition that clinical outcomes are available through the use of music therapy intervention in conjunction with standard, well-established treatment methods. CONCLUSIONS: Music therapy is beneficial for patients receiving care for mental disorders and establishing this therapy within mental health service provision should be considered. PMID- 30290567 TI - An Irish case of pulmonary emboli secondary to clozapine therapy. AB - BACKGROUND: Clozapine is the prototype atypical antipsychotic used for treatment resistant schizophrenia, but its use has been limited by the well-established association with agranulocytosis. An increased risk of other serious adverse events such as myocarditis and thromboembolism has also been suggested to be associated with clozapine therapy. AIMS: We describe an Irish case of multiple pulmonary emboli detected by CT pulmonary angiogram thought to be secondary to clozapine therapy. CONCLUSION: Although clozapine is a very efficacious antipsychotic its many side-effects limit its use. Pulmonary embolism must be remembered as a potential rare side-effect in clozapine therapy. Underlying mechanisms are still unclear although several have been proposed. PMID- 30290568 TI - Bullying and mental health in national school children.

AB - OBJECTIVES: To describe the characteristics of the patient groups with severe and enduring mental illness residing in high support community residences in Dublin North East Mental Health Service and the impact of a rehabilitation and recovery service on their outcomes since the instigation of that service. METHOD: Data was collected retrospectively on current and past residents from case notes and staff interviews. Data included demographics, psychiatric history and results of rehabilitation interventions. The results were compiled and analysed using descriptive statistics. RESULTS: Fifty patients were identified. The majority were male (62%) with a diagnosis of paranoid schizophrenia (66%).The levels of co morbid alcohol and drug misuse were 48% and 36% respectively. Histories of verbal/physical aggression were found in 70% and noncompliance in 60%. Two thirds of patients had a past history of being detained under the Mental Treatment Act (1945). Ninety-four per cent were unemployed at admission to the residence and following rehabilitation intervention 60% were linked with vocational training programmes and 10% with community employment schemes. 'New long-stay' and 'old long-stay' patients showed a trend towards poorer outcomes, whereas patients who had previously lived in the community showed a trend towards progressing to lower levels of support. CONCLUSIONS: Positive outcomes were achieved following active rehabilitation interventions, but there remained a cohort of patients whose needs could not be met in a supported community rehabilitation residential programme. This highlights the need to ensure that a range of rehabilitation services from inpatient to supported community placement are provided to meet the needs of patients with severe and enduring mental illness with complex needs. PMID- 30290573 TI - Routine investigations in paediatric psychopharmacology. AB - OBJECTIVES: This study examines (1) what are the minimum accepted baseline investigations recommended in the literature prior to prescribing in child psychiatry and (2) whether these investigations are routinely performed. METHOD: Medical literature on prescribing in child and adolescent psychiatry was reviewed, and a list of minimum baseline investigations recommended in the literature was established. A postal survey was performed to establish what current clinical practice is among child and adolescent psychiatrists. Current practice was compared with the recommendations in the literature. RESULTS: There are nine minimum accepted baseline investigations which are consistently recommended in the literature on child psychiatry. Six investigations are routinely performed by over 75% of respondents. However only 30% (n = 16) reported that they 'always' carried out eight or more of the nine recommended minimum investigations. CONCLUSIONS: A consensus statement is necessary, providing a list of recommended investigations prior to prescribing in child and adolescent psychiatry. Continuing medical education can then highlight the importance of these investigations. PMID- 30290574 TI - Admissions to a national forensic hospital 1997-2003. AB - OBJECTIVES: We set out to review all admissions from the criminal justice system to the Central Mental Hospital from January 1997 to December 2003, with particular attention to patient diagnoses, offences, source of admission, length of stay, and patterns of discharge. This study was undertaken to assist with future service planning and determination of resource needs. METHODS: The service maintains a combination of electronic and handwritten records of all admissions. Information was extracted concerning all admissions from January 1, 1997 to December 30, 2003. The data was analysed using a statistical package, SPSS 11.0 for Windows. RESULTS: Nine hundred and eighty-six admissions of 780 individuals from the criminal justice system were recorded from January 1997 to December 2003. There has been an increase in the proportion of patients admitted suffering with severe mental illness. There has also been a significant shift in the pattern of discharges, with a higher proportion of patients leaving to return to their local hospital. The proportion of admissions returned to prison has fallen from 91.1 % in 1999 to 64.7% in 2003, while 3.3% of individuals admitted became new long-stay cases. CONCLUSIONS: A shift in the profile of patients admitted in recent years reflects changes within the National Forensic Mental Health Service. An increased provision of regular and structured psychiatric input to the prisons has facilitated the identification of prisoners with mental illness. The shift from prison liaison to diversion from the Criminal Justice System to mental health services is however in its early stages. PMID- 30290575 TI - Analysis of referral letters to a department of old age psychiatry. AB - OBJECTIVE: There is a paucity of literature on the content of referral letters to psychiatric services and few relating specifically to referrals to a department of old age psychiatry. There has been a significant increase in referrals over the last five years to this service, which may reflect the ageing population and a greater awareness of the service. Our objective was to evaluate the quality and legibility of information received, clarity of reason for referral and details of pre-referral management. METHODOLOGY: The clinical records of the first 100 referrals in 2002 to this department were analysed. The referral letters were examined for the documentation of a number of demographic variables, reason for referral, interventions to date and level of urgency. RESULTS: The clinical records of nine patients did not have an identifiable referral letter at the time of this analysis. Of the remaining 91 analysed, 59% were referred by their GP, 33% were inpatient liaison referrals and 8% from outpatient departments. In the majority, patients' details were given, however, only 30% included a phone number. Next-of-kin was mentioned in 29%. GP's name was included in 71% of referrals from OPD and 7% of liaison referrals. The level of urgency was stated in 19%. Whether a domiciliary or OPD visit would be more appropriate was stated in 22%. The reason for referral was clear in 75%, with 43% including some aspect of Mental State Examination, 7% had included a MMSE score, 1% mentioned level of suicide risk. Thirty-one per cent had pre-referral investigations and 45% had pre referral treatment documented. The letters were clearly legible in 73%. CONCLUSION: The information in the referral letter in many cases was insufficient to prioritise and expedite appropriate assessment. It is planned to introduce a proforma referral form, specific to old age psychiatry, which would include the information which is required and which would, hopefully, lead to a more efficient service.

AB - PURPOSE: Planes of reference for orbital fractures (PROF) was developed to standardize measurements made on orbital computed tomography scans. This study describes the use of PROF in determining the location along the orbital floor where the posterior ledge (PL) most commonly occurs. The transverse inclination and anterior-posterior inclination of the orbital floor will also be measured. METHODS: This study evaluates 104 patients with unilateral orbital fracture. Fifty-two patients had intact infra-orbital margin (IM) and 52 had fractured IM. Facial computed tomography scans were analyzed using Osirix Lite Digital Imaging and Communications in Medicine Viewer version 7.0.1 (Geneva, Switzerland). All skull positions were standardized by orientation according to Frankfurt and mid sagittal planes. Measurements of distance of PL from IM were determined in the sagittal view. Measurements of the inclination of the orbital floor in the transverse and anterior-posterior sections were done on the coronal and sagittal views respectively. RESULTS: For patients with intact and fractured IM, the mean distances of PL from IM were 22.1 mm (95% CI: 21.2-23.0) and 21.1 mm (95% CI: 20.2-21.9) respectively. Mean transverse inclination was 19.4 degrees (95% CI: 18.3-20.5). Mean anterior-posterior inclination was 15.5 degrees (95% CI: 14.5 16.5). CONCLUSION: Planes of reference for orbital fractures is a simple and effective method to acquire standardized measurements of the orbital cavity on computed tomography scans. Understanding the commonest location of PL and the orientation of the orbital floor in 3-dimensional space allows surgeons to perform dissection with greater precision. PMID- 30290583 TI - Effect of Prior Radiotherapy on the Outcome of Submental Island Flap in Head and Neck Reconstruction. AB - The submental island flap is a new alternative to the reconstruction of various head and neck defects. But there has been a relative paucity of information about the use of this flap in irradiated patients. The authors present their preliminary experience in the use of this flap in irradiated and nonirradiated patients. Eighty-one patients (53 nonirradiated and 28 irradiated patients) underwent reconstruction with the submental island flap between March 2011 and August 2017. The authors have 13 patients of venous congestion (7 in nonirradiated and 6 in irradiated group), 7 patients of partial necrosis of the flap (4 in nonirradiated and 3 in irradiated group). The authors also have 3 patients of transient paralysis of marginal mandibular nerve (2 in the nonirradiated and 1 in irradiated group), and 2 patients of pharyngo-cutaneous fistula in nonirradiated group. The authors have no cases of total flap loss, permanent paralysis of marginal mandibular nerve but have dehiscence of the submental area after harvesting the flap in an irradiated patient. When combined with the reported experience of other surgeons, the authors' preliminary experience showed that the submental island flap was an excellent alternative in the reconstruction of head and neck defects in both irradiated and nonirradiated patients because of its reliability, versatility, and relatively acceptable complications. PMID- 30290584 TI - Comparing Spontaneous Closure and Paper Patching in Traumatic Tympanic Membrane Perforations. AB - The authors aim to analyze the effects of oral antibiotic treatment for traumatic tympanic membrane perforations and to compare the outcomes of patients with traumatic tympanic membrane perforation after paper-patching procedure and spontaneous healing.In this study, 80 patients with traumatic tympanic membrane perforation diagnosed in the otorhinolaryngology emergency department and outpatient clinic from March 2010 to January 2015 were retrospectively reviewed. If the patient is diagnosed at first week and the edge of perforation is moist with blood, our routine procedure is paper-patching (group 1). However, if the patients reject treatment or delay in admission, the authors follow up patients for spontaneous closure (group 2). Some of the patients got oral antibiotics for 7 days (amoxicillin/clavulanic acid, 1000 mg 2 times/d) while some others did not. Closure rates and effectivity of oral antibiotics were evaluated and compared between 2 groups.In total, 80 patients were analyzed. The closure rates of perforations were 95.2% for group 1 (n = 42) and 81.6% for group 2 (n = 38). Although the paper-patched patients (group 1) perforation closure rate (95.2%) is higher than the nontreated patients (group 2) closure rate (81.6%), it is not statistically significant (P > 0.05). Antibiotic administered 55 patients had a significantly higher closure rate (94.5%) than the 25 patients who are not treated with antibiotics (76%) (P = 0.023; P < 0.05).In patients with traumatic tympanic membrane perforations, spontaneous closure rate is quite high. This study showed us that antibiotherapy and paper-patch treatments increase the healing rates. PMID- 30290585 TI - Cavernous Sinus and Parasellar Region: An Endoscopic Endonasal Anatomic Cadaver Dissection. AB - The aim of this study was to investigate the neurovascular structures of the cavernous sinus with the endonasal endoscopic transpterygoid approach on fresh human cadavers. Additionally, the course of internal carotid artery (ICA) and relevant anatomy was thoroughly investigated to refine the anatomical landmarks, exposure difficulties, potential complications, and limitations using the endonasal endoscopic technique. This study was carried out at an otolaryngology department of a tertiary medical center between June 2014 and June 2015. The surgical dissection was performed on 10 fresh human cadaver specimens using paranasal sinus and skull base endoscopic instruments. Cavernous sinuses and parasellar area were explored via an endoscopic endonasal transpterygoid approach. Dehiscence was present in 5 (25%) cavernous ICAs. Projection of the cavernous ICA on the whole lateral sphenoid wall was prominent in 6 (%30) sphenoid sinuses. Anterior curve was prominent in 12 (60%) cavernous ICAs, whereas posterior was prominent in 7 (35%). Mean distance between the lateral wall of eustachian tube orifice and petrous ICA was 19.50 +/- 1.05 mm (range 18 22 mm). Cranial nerves of the cavernous sinus showed no variation. Control of the ICA is critical during the endonasal endoscopic approach to the cavernous sinus and skull base. The vidian nerve is a reliable and important landmark to the petrous ICA in the transpterygoid approach. Dissection of the eustachian tube and its relation to the ICA has to be kept in mind during nasopharyngeal surgery.

AB - Calvarial and dural metastases of papillary thyroid carcinomas (PTC) are rarely reported in the medical literature. Most frequent calvarial metastases are seen to originate from lung, breast, and prostate cancers. Thyroid cancer metastases are generally well vascularized and cause destruction in the bone tissues. First choice of treatment in distant metastases of PTC is surgery and radioactive iodine treatment for the primary cause. Postsurgical radiotherapy is used in accepted and suitable patients. PMID- 30290587 TI - Associations of TCF7L2 gene polymorphisms with the risk of diabetic nephropathy: A case-control study. AB - The aim of the study was to explore the correlation between rs7903146 and rs290487 polymorphisms in transcription factor 7-like 2 (TCF7L2) gene and diabetic nephropathy (DN) in Chinese Han population.Polymerase chain reaction restriction fragment length polymorphism was used to determine genotypes of TCF7L2 polymorphisms in 90 patients with DN and 96 diabetes patients without DN. The linkage disequilibrium (LD) and haplotype analysis were performed with haploview software. Hardy-Weinberg equilibrium was assessed in the control group based on the genotype distributions of TCF7L2 polymorphisms. The genotype, allele, and haplotype distribution differences between the case and control groups were analyzed by chi-squared test, and odds ratio (OR) and 95% confidence interval (CI) were used to indicate the relative risk of DN.People carrying TT genotype of rs7903146 were more easily to be attacked by DN than CC genotype carriers (P = .02, OR = 4.26, 95% CI = 1.12-16.24). Meanwhile, T allele also showed 1.85 times risk to suffer from DN compared with C allele (OR = 1.85, 95% CI = 1.02-3.10). However, there was no significant difference in genotypes and alleles frequencies of rs290487 between 2 groups. The strong LD existed between the 2 single nucleotide polymorphisms and haplotype T-T (rs7903146-rs290487) increased the susceptibility to DN (OR = 2.63, 95% CI = 1.31-5.25).TCF7L2 rs7903146 polymorphism may be associated with the susceptibility to DN in Chinese Han population, but rs290487 is not. Additionally, haplotype is also a risk factor for DN. PMID- 30290588 TI - Worldwide research productivity in the field of back pain: A bibliometric analysis. AB - BACKGROUND: This study aimed to show the world research productivity in the field of back pain and to help researchers follow the scientific development and promote the cooperation in this field. METHODS: Web of Science (WoS) database was searched from 1995 to 2016 without other restrictions. The keywords were as follows: "lumbar NEAR pain," "back pain," "dorsalgia," "backache," "lumbago," "back NEAR disorder," and "discitis." The following information of retrieved articles was analyzed: countries/territories, journals, publication year, authors, citation reports, and institutions. Publication activity was further adjusted for countries by gross domestic product (GDP) and population size. RESULTS: A total of 50,970 articles were retrieved in WoS database from 1995 to 2016. The United States published the biggest number of articles (16,818, 33.00%), followed by England (4,582, 8.99%), Germany (3,871, 7.60%), Canada (3,613, 7.09%), and Australia (3,063, 6.01%). Sweden ranked the first after adjusted for publication, and Netherlands ranked the first after adjusted for GDP. Besides, there was positive correlation between total number of publications and GDP for each country (P < .05). Harvard University was the most productive institution (917, 1.80%), Maher CG was the most productive author (229, 0.45%) and Spine was the most popular journal (3605, 7.07%) in the field of back pain research. Moreover, the article titled "Clinical importance of changes in chronic pain intensity measured on an 11-point numerical pain rating scale" in Pain had the highest citations (1749). CONCLUSION: There was a significant increase in annual publications concerning back pain research worldwide. The total number of publications was positively associated with GDP in main productive countries. The United States was the most productive country, Harvard University was the most productive institution, Maher CG was the most productive author and Spine was the most popular journal in the field of back pain. PMID- 30290589 TI - Increased serum pentraxin-3 level predicts poor prognosis in patients with colorectal cancer after curative surgery, a cohort study. AB - Pentraxin-3 (PTX3) is a glycoprotein involved in inflammation and immune regulation of cancer. The aim of this study was to evaluate the serum PTX3 level in patients with colorectal cancer (CRC) and analyze its prognostic significance.A total of 263 consecutive patients underwent radical resection for primary CRC and 126 healthy controls were enrolled in this study. Serum PTX3 level was measured within the day before surgery though enzyme-linked immunosorbent assays, comparing with the level of healthy control. Baseline demographic and clinical characteristics were recorded. The association between serum PTX3 level and survival outcome was analyzed by the Kaplan-Meier with Log Rank test and Cox regression methods.Mean serum PTX3 level in CRC patients was higher than that of healthy control (13.8 +/- 3.2ng/mL versus 3.3 +/- 1.2ng/mL, P < .001). Finally, 55 (20.9%) patients out of all 263 patients studied had died during following-up period. All patients were divided into 2 groups using the optimal cutoff value (12.6 ng/mL) of PTX3 level using a sensitivity of 68.0% and a specificity of 71.7% as optimal conditions from receiver operating curve analysis. Patients with a PTX3>=12.6ng/mL had poorer 5 years overall survival rate (76.6% versus 67.8%, P = .025) patients with a PTX3 < 12.6ng/mL in univariate analysis and serum PTX3 level also been confirmed as an independent predictor for survival for CRC in multivariate analysis (Hazard ratio, 1.468; 95% [confidence interval] CI, 1.081-1.976; P < .001).Serum PTX3 level can serve as an independent prognostic biomarker for CRC patients after curative resection. PMID- 30290590 TI - Malakoplakia as a cause of severe hypercalcemia through ectopic 25-hydroxyvitamin D3 1-alpha-hydroxylase expression: A case report. AB - RATIONALE: Malakoplakia is a rare disease characterized by the presence of nongranulomatous macrophage infiltration. In most cases, it affects the urinary tract. Malakoplakia can cause acute kidney injury when it is localized in the kidneys. PATIENT CONCERNS: Here, we report the case of a 65-year-old female patient with renal malakoplakia responsible for hypercalcemia. During her initial assessment, she was also diagnosed 25-OH vitamin D insufficiency, for which she was prescribed oral cholecalciferol. Three months later, she developed severe hypercalcemia with normal 25-OH vitamin D and parathyroid hormone levels and high 1,25-dihydroxyvitamin D levels. DIAGNOSES: After a superimposed granulomatous disease was excluded, malakoplakia cells were suspected to be responsible for the abnormal 25-hydroxyvitamin D3 1-alpha-hydroxylase activity, which was confirmed by immunohistochemistry. INTERVENTIONS: Cholecalciferol was stopped, the patient was rehydrated with intravenous physiological saline, and prednisone was initiated to decrease the enzyme activity. OUTCOMES: Six months later, she displayed normal serum calcium, 25-OH vitamin D and 1,25-dihydroxyvitamin D levels. LESSONS: This case illustrates that malakoplakia may exhibit ectopic 25 hydroxyvitamin D3 1-alpha-hydroxylase activity and cause severe hypercalcemia upon vitamin D supplementation. Therefore, such supplementation should not be given in malakoplakia patients without an actual deficiency and requires careful monitoring of serum calcium. PMID- 30290591 TI - Fatal case of hemophagocytic lymphohistiocytosis associated with group B streptococcus sepsis: A case report. AB - RATIONALE: Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease characterized by an excessive systemic inflammatory response. HLH is classified as primary or secondary, where the latter may occur in association with many infections. However, no case of HLH has been previously associated with group b streptococcus (GBS) sepsis. PATIENT CONCERNS: We present a fatal case of HLH in a 5-year-old girl with GBS sepsis. DIAGNOSIS: The present patient met 5 of the HLH criteria: fever, splenomegaly, bicytopenia, hypertriglyceridemia and/or hypofibrinogenemia, and hyperferritinemia. GBS was identified in 2 sets of peripheral blood bacterial cultures. INTERVENTIONS: Empirical antibiotics, inotropes, and immunoglobulins were administered. OUTCOMES: The clinical course of the patient was fulminant and the patient died of septic shock 10 hours after admission to the hospital. LESSONS: We suggest GBS infection can cause HLH and early awareness of HLH associated with GBS infection and proper effective treatment are necessary to reduce mortality.

AB - RATIONALE: Neuroendocrine tumors (NETs) with hyperprocalcitonin are relatively rare with a low incidence rate. PATIENT CONCERNS: An afebrile 63-year-old male with persistent low back pain unexpectedly presented with an extreme hyperprocalcitonin. Radiological assessment revealed thickening of the esophageal wall with vertebral bone destruction and liver lesions. Endoscopy showed an irregular-shaped esophageal lesion which turned out to be poorly-differentiated NETs. DIAGNOSIS: Esophageal NETs with multiple metastases. INTERVENTIONS: The patient was treated with chemotherapies, and was evaluated by procalcitonin level and radiology within follow-up. OUTCOME: The procalcitonin levels were altered in line with the therapeutic response and disease progression during the treatment course. LESSONS: Increased procalcitonin occurs in several malignancies with neuroendocrine components, such as NETs of the digestive system. PMID- 30290594 TI - Can radial bone mineral density predict spinal bone mineral density in patients with advanced Duchenne muscular dystrophy? AB - In advanced Duchenne muscular dystrophy (DMD), patients with high bone fracture risk due to osteoporosis, it is difficult to measure spinal bone mineral density (BMD) because of maintaining proper posture. This study began with the idea that if we diagnose and manage osteoporosis by predicting spinal BMD through easily testable radial BMD, we could prevent fracture and improve quality of life in DMD patients. In 61 DMD patients aged 20 years or older who were admitted to Gangnam Severance Hospital from April 2013 to May 2015, radial BMD and spinal BMD were measured to compare their Z-scores. In 45 patients, the z-score was less than 2.0 in spinal BMD defined as osteoporosis. And the optimal range of Z-score in the radius was -5.2 to -5.0 (sensitivity 78.9%, specificity 71.4%). Only through the radius BMD, spinal BMD can be predicted and we suggest appropriate times for treatments. PMID- 30290593 TI - Expressions of KAI1 and E-cadherin in nonsmall cell lung cancer and their correlation with vasculogenic mimicry. AB - BACKGROUND: Metastasis and recurrence are the most common reasons for treatment failure of nonsmall cell lung cancer (NSCLC). Vasculogenic mimicry (VM, new blood supply formation in malignant tumors), E-Cadherin (a calcium-dependent transmembrane glycoprotein that mediates intercellular adhesion), KAI1 (a suppressor gene of tumor metastasis) are all valuable factors for metastasis and prognosis in diverse common human cancers. However, the correlation of VM, E Cadherin, and KAI1 in NSCLC is still unclear. In this study, we analyzed the correlations among these factors as well as their respective correlations with clinicopathological parameters and survival in NSCLC. METHODS: The level of VM, E Cadherin, and KAI1 in 163 tissue samples of NSCLC was examined by immunhistochemistry. Clinical data were also collected. RESULTS: Levels of VM was significantly higher, and levels of KAI1 and E-Cadherin significantly lower in NSCLC tissues than in normal lung tissues. Levels of VM were positively associated with lymph node metastasis (LNM), size, grade, and tumor node metastasis (TNM) stages, and negatively associated with patients' overall survival (OS). Levels of KAI1 and E-Cadherin were negatively correlated with LNM, size, grade, and TNM stage, and positively associated with patients' OS. In multivariate analysis, high levels of VM, E-Cadherin, and KAI1, as well as TNM stages were independently correlated with lower OS in patients with NSCLC. CONCLUSION: VM and the expression of E-Cadherin and KAI1 may represent promising metastatic and prognostic biomarkers, as well as potential therapeutic targets for NSCLC. PMID- 30290595 TI - Risk factors related to metastasis of para-aortic lymph nodes in pancreatic ductal adenocarcinoma: A retrospective observational study. AB - This study was designed to explore the risk factors related to metastasis of para aortic lymph node (PALN).Clinicopathologic data of 241 patients with resectable or borderline resectable pancreatic cancer who underwent pancreaticoduodenectomy with extended lymphadenectomy between January 2008 and December 2015 were collected, potential factors related to metastasis of PALN were analyzed.Positive rate of PALN was 19.5% (47/241). Univariate analysis showed that back pain (P = .028), preoperative CA19-9 level (P < .001), tumor size (P < .001), portal vein (PV)/superior mesenteric vein (SMV) invasion (P < .001), superior mesenteric artery (SMA) invasion (P < .001), and diameter > 1.0 cm were in correlation with PALN involvement, multivariate analysis revealed that preoperative CA19-9 level, PV/SMV invasion, SMA invasion and diameter > 1.0 cm were independent risk factors to metastasis of PALN. Patients with LN8+ had a higher positive rate of PALN than with LN8- (38.1% vs 15.6%, P = .001), similar results could be found when LN12+ (35.8% vs 13.2%, P < .001) and LN14+ (41.2% vs 11.0%, P < .001), multivariate analysis showed that LN8+ and LN14+ were closely in correlation with PALN metastasis.Several factors were related to the status of PALN, preoperative CA19 9 level, PV/SMV invasion, SMA invasion and diameter > 1.0 cm were 4 independent risk factors to PALN metastasis. LN8+ and LN14+ were 2 strong predictors of PALN metastasis. A comprehensive analysis covering all possible risk factors related to metastasis of PALN should be given before design of treatment plan whenever involvement of PALN was suspected. PMID- 30290596 TI - Arthroscopic management of elbow synovial chondromatosis. AB - OBJECTIVE: We aimed to identify factors that affect pain, complications, and function following elbow arthroscopy for elbow synovial chondromatosis. METHODS: We retrospectively reviewed the cases of all patients with elbow synovial chondromatosis treated by arthroscopic synovectomy and loose body removal between January 2000 and January 2016 at our institution. Eleven patients were enrolled (8 male; mean age, 41.7 years). The mean duration of symptoms was 13.7 months, and all patients had a decreased range of motion (ROM) in the affected elbow. By Milgram criteria, there was 1 phase II case, and 10 cases were phase III. RESULTS: All patients were followed postoperatively (mean follow-up, 65 months). The preoperatively restricted ROM of 100 degrees flexion (range, 78 degrees -120 degrees ) and extension of 30 degrees (range, 15 degrees -40 degrees ) were improved to 130 degrees flexion (range, 120 degrees -140 degrees ) and -5 degrees hyperextension (range, -10 degrees -0 degrees ). Pain, recorded as the pain subscore of the American Shoulder and Elbow Surgeons questionnaire for elbows, was significantly improved from 32 points (range, 20-50) preoperatively to 85 (range, 70-100) postoperatively (on a scale ranging from 0 [worst pain] to 100 [pain-free]). Recurrence occurred in 2 patients (18.2%) who then received arthroscopic synovectomy and loose body removal again. There were no fractures or neurovascular complications, and no patient developed an infection. CONCLUSION: Arthroscopic management of synovial chondromatosis of the elbow was an effective and safe therapeutic method. After the intervention, immediate and durable improvement of elbow function can be expected. PMID- 30290598 TI - Clinical observation of 60 cases of treating cognitive disorder after cerebral injury in combination with scalp acupuncture and cognitive training. AB - To observe the clinical effect of scalp acupuncture combined with cognitive training on cognitive disorder after cerebral injury.Around 60 cases of cerebral injury patients for hospitalization in rehabilitation department of Chongqing Three Gorges Central Hospital from July in 2015 to June in 2017 are divided into control group and treatment group of 30 cases for each at random. The control group received routine treatment and cognitive rehabilitation training for 12 weeks. The treatment group received conventional treatment, cognitive rehabilitation training, and scalp acupuncture. Acupuncture with a scalp acupuncture is provided for the treatment group besides adopting above conventional treatment and rehabilitation training method.Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) score of both groups increases obviously after treatment compared with that before treatment, and there is difference (P < .01) through contrast. And LOTCA score of treatment group is higher than that of control group (P < .05) after treatment.Scalp acupuncture in combination with cognitive training can effectively improve cognitive disorder degree of patients with cerebral injury, and the effect is more significant compared with simple cognitive rehabilitation training, thus it is worth of research and application. PMID- 30290599 TI - Renal resistive index and aortic knob width relationship as a predictor of renal prognosis in essential hypertension. AB - The scientific studies that have been conducted so far highlight that renal resistive index (RI) and aortic knob width (AKW) indicate poor prognosis regarding renal and cardiovascular mortality. But the existence of a direct relationship RI and AKW is unclear. This study aims investigating the relationship between RI and the measured AKW in chest radiography of the patients with hypertensive nephropathy who do not require renal replacement therapy.This prospective study included 268 consecutive patients with essential hypertension. Patients were divided into 2 groups as RI >=0.7 and RI <0.7. The ROC curve, sensitivity, and specificity ratios were evaluated to determine which AKW value is the best predictive one for the RI >=0.7.The cutoff point of AKW was evaluated as >=36 for the cases with RI >=0.7: sensitivity was 71.22%; specificity was 71.32%; the positive predictive value (PPV) was 72.79; the negative predictive value (NPV) was 69.70, and the accuracy was 71.27. Area under the ROC curve +/- standard error (AUC +/- SE) = 0.729 +/- 0.031 (P < .001).AKW can provide important predictive information about the subclinical renal dysfunction in hypertensive patients with RI >=0.7. Moreover; AKW is a predictive factor for both the diagnostic and prognostic evaluation of renal pathologies. PMID- 30290597 TI - Normal pregnancy induced glucose metabolic stress in a longitudinal cohort of healthy women: Novel insights generated from a urine metabolomics study. AB - During normal pregnancy, mothers face a unique physiological challenge in the adaptation of glucose metabolism in preparation for the metabolic stress presented by fetal development. However, the responsible mechanism remains elusive. The purpose of this study is to investigate the mechanism of the metabolic stress of glucose metabolism in pregnant women using metabolomics method.A Ultra Performance Liquid Chromatography Quadrupole Time-of-Flight Mass Spectrometer-based untargeted metabolomics study was performed to investigate the dynamic urinary signature of the intermediates of glucose metabolism in a longitudinal cohort of 232 healthy pregnant women in their first, second, and third trimesters.Twelve glucose metabolic intermediates were screened out from hundreds of candidate metabolites using partial least squares discriminant analysis models. These 12 markers were mainly involved in the metabolic pathways of insulin resistance, glycolysis/gluconeogenesis, tricarboxylic acid cycle, nonabsorbable carbohydrate metabolism, and N-glycan biosynthesis. In particular, L-acetylcarnitine, a metabolite that is beneficial for the amelioration of insulin resistance, decreased in a time-dependent manner during normal pregnancy. Moreover, thiamine pyrophosphate, an intermediate product of glycolysis/gluconeogenesis, significantly increased in the second trimester, and argininosuccinic acid and oxalosuccinic acid, intermediates involved in the tricarboxylic acid cycle, significantly decreased in the third trimester, suggesting an increased glucose demand in the maternal body during fetal development.These findings provide novel insight into the normal pregnancy induced elevation of insulin resistance and glycolysis/gluconeogenesis, as well as the observed reduction in the aerobic oxidation of glucose. PMID- 30290600 TI - Manifestations and outcomes of nocardia infections: Comparison of immunocompromised and nonimmunocompromised adult patients. AB - Nocardia is a ubiquitous environmental pathogen that causes infection primarily following inhalation into the lungs. It is generally thought to cause infection primarily in immunocompromised patients, but nonimmunocompromised individuals are also at risk of infection. We sought to compare risk factors, clinical manifestations, diagnostic approach, treatment, and mortality in immunocompromised and nonimmunocompromised adults with nocardiosis.We studied all adults with culture-proven Nocardia infection at a tertiary care hospital from 1994 to 2015 and compared immunocompromised with nonimmunocompromised patients. The immunocompromised group included patients who had a solid organ transplant, hematopoietic cell transplant (HCT), hematological or solid tumor malignancy treated with chemotherapy in the preceding 90 days, inherited immunodeficiency, autoimmune/inflammatory disorders treated with immunosuppressive agents, or high dose corticosteroid therapy for at least 3 weeks before the diagnosis of nocardiosis.There were 112 patients, mean age 55 +/- 17 years; 54 (48%) were women. Sixty-seven (60%) were immunocompromised, and 45 (40%) were nonimmunocompromised. The lung was the site of infection in 54 (81%) immunocompromised and 25 (55%) nonimmunocompromised patients. Pulmonary nocardiosis in immunocompromised patients was associated with high-dose corticosteroids, P = .002 and allogeneic HCT, P = .01, and in nonimmunocompromised patients with cigarette smoking, bronchiectasis, and other chronic lung diseases, P = .002.Cavitation occurred only in the immunocompromised group, P < .001. Disseminated infection was more common in the immunocompromised, P = .01, and was highest in solid organ transplant recipients, P = .007. Eye infection was more common in nonimmunocompromised patients, P = .009. Clinical signs and symptoms did not differ significantly between the 2 groups. The initial treatment for most patients in both groups was trimethoprim-sulfamethoxazole with or without a carbapenem. All-cause 1-year mortality was 19%; 18 (27%) immunocompromised and 3 (7%) nonimmunocompromised patients died, P = .01.Immunocompromised patients with nocardiosis had more severe disease and significantly higher mortality than nonimmunocompromised patients, but clinical presentations did not differ. PMID- 30290601 TI - 99mTc-3PRGD2 single-photon emission computed tomography/computed tomography for the diagnosis of choroidal melanoma: A preliminary STROBE-compliant observational study. AB - Recent successes in monitoring and diagnosing a variety of tumors using Tc-PEG4 E[PEG4-c(RGDfK)]2 (Tc-3PRGD2) single-photon emission computed tomography (SPECT) imaging encouraged us to expand the use of this tracer. This case-control study aimed to evaluate the feasibility of Tc-3PRGD2 imaging for detecting choroidal melanoma (CM) and for monitoring tumor response to plaque brachytherapy (PB). Ten consecutive patients with CM who underwent Tc-3PRGD2 imaging before and 3 months after PB were reviewed. The tumor-to-occipital bone (T/O) and mirrored contralateral normal tissue-to-occipital bone (N/O) ratios were calculated by region of interest analysis at baseline and 3 months post-PB. T/O values were compared between patients with CM with comorbid secondary retinal detachment (RD) and those without RD. The relationship between T/O value and tumor volume was also investigated. Tc-3PRGD2 SPECT/CT showed focal uptake in CM. The mean T/O ratio before PB was 1.90 +/- 1.26 and the mean N/O ratio was 0.80 +/- 0.21 (P = .02). The Tc-3PRGD2 concentrations in 5 patients with CM with RD were higher (T/O = 2.69 +/- 1.39) than in those without secondary RD (T/O = 1.10 +/- 0.18) (P = .008). T/O ratios at 3 months post-PB were significantly lower than that at baseline (1.23 +/- 0.59, P = .03). There was a linear relationship between T/O and tumor volume (y-hat = 0.028 + 0.003x, R = 0.768, P = .001). The 95% confidence interval for the (T/O)/volume ratio was 0.002 to 0.005. Tc-3PRGD2 imaging is a feasible modality for the diagnosis of CM. Furthermore, follow-up for at least 20 months after PB indicated that coanalysis of Tc-3PRGD2 imaging and tumor volume may provide a promising prognostic predictor in patients with CM. PMID- 30290602 TI - Viabahn stent graft compared with prosthetic surgical above-knee bypass in treatment of superficial femoral artery disease: Long-term results of a retrospective analysis. AB - The prosthetic surgical above-knee bypass (pAKB) is a standard therapy in superficial femoral artery (SFA) occlusive disease in absence of suitable vein. Viabahn graft has been established as a promising alternative. Since limited comparative data are available, we conducted a retrospective study to compare long-term outcomes of these 2 therapies in a real-world setting.Records of 52 patients (60 limbs), who were treated by pAKB (29 limbs) or Viabahn (31 limbs) were reviewed. Patients were followed up by clinical assessment, physical examination, and resting ankle brachial index (ABI) after 3, 6, 12 months and yearly thereafter. Long-term data were available for 97% in the Viabahn and 93% for pAKB after 73 +/- 3.7 months (mean +/- standard error [SE]).Long-term primary and secondary patencies in Viabahn group were 40% and 70%, respectively, after 63 +/- 2.8 months (mean +/- SE). Total lesion length was 19 +/- 11.06 cm (mean +/- SE), graft size was 6 +/- 0.72 mm (mean +/- SE). Hospital stay was 4.8 +/- 0.72 days (mean +/- SE). Limb salvage was achieved in 90%. Patients in the pAKB group showed a total lesion length of 24.39 +/- 1.97 cm (mean +/- SE), graft size was 7 +/- 0.99 mm (mean +/- SE). Long-term analysis after 83 +/- 6.8 months (mean +/- SE) revealed a primary patency of 78% with a secondary patency of 94%. Hospital stay was 10.4 +/- 1.27 days (mean +/- SE). Limb salvage was ensured in 97%. Long term primary patency was lower for Viabahn (P = .044), secondary patency (P = .245), and leg salvage (P = .389) were not significantly different. However, hospital stay was shorter (P = .0002) for Viabahn.Long-term analysis of Viabahn revealed a significantly lower primary patency, a similar secondary patency, limb salvage, and significantly shorter hospital stay when compared with pAKB. Our data suggest that pAKB is still a valuable option in patients suitable for an open operation. However, Viabahn can be used as a less invasive treatment in high risk patients. PMID- 30290603 TI - The clinical efficacy of using autologous platelet-rich plasma in total hip arthroplasty: A retrospective comparative study. AB - This study evaluated whether intra-articular platelet-rich plasma (PRP) might prevent postoperative bleeding in total hip arthroplasty (THA).In this study, 260 hips that underwent THA were evaluated randomly by paramedical staffs, 130 of which involved the intraoperative use of PRP, and 130 of which served as control group. Postoperative blood loss (drain bag volume), estimated blood loss, and change in hemoglobin (Hb) at day 1, 2, 4, and 7 were analyzed, respectively.PRP treated group had a significant decrease in mean postoperative blood loss (92.6 +/- 168.2 mL) compared to control group (682.3 +/- 185.5 mL, P < .01). The mean postoperative estimated blood loss (526.1 +/- 236.1 mL) in the PRP-treated group was significantly less than that in the control group (629.2.2 +/- 142.3 mL, P < .01). There was a statistically significant difference in Hb value (mg/dL) at day 1, 2, 4, and 7 (-1.35 vs -1.98, -1.59 vs -2.52, -1.96 vs -2.82, and -1.76 vs 2.47, P < .05).We found a significant reduction in postoperative blood loss (drain bag volume), estimated blood loss, and change in Hb after the use of autologous platelet gel in patients of THA, and PRP appears to be effective in reducing postoperative bleeding in THA. PMID- 30290604 TI - Pain monitoring and management in a rehabilitation setting after total joint replacement. AB - Total hip replacement (THR) and, particularly, total knee replacement (TKR), are painful surgical procedures. Effective postoperative pain management leads to a better and earlier functional recovery and prevents chronic pain. Studies on the control of pain during the postoperative rehabilitation period are not common. The aim of this study is to present results of a perioperative anesthetic protocol, and a pain treatment protocol in use in the Orthopaedic and the Rehabilitation intensive units of our Hospital. 100 patients (50 THR and 50 TKR) were retrospectively included in this observational study. Numeric Rating Scale (NRS) for pain at rest registered in the clinical sheet was retrieved for all patients and analyzed with respect to the spinal anaesthesia given for the surgery, local analgesia, analgesia protocol adopted during the postoperative days in the Orthopaedic Unit, the antalgic treatment given during the stay within the Rehabilitation Unit, the postoperative consumption of rescue pain medication, and any collateral effect due to the analgesic therapy. Patients reached standard functional abilities (walking at least 50 meters and climbing/descending stairs) at a mean length of 8 days without medication-related complications. Mean NRS during the time of stay was 1.3 +/- 0.3 for THR and 1.3 +/- 0.2 for TKR) and maximum mean NRS was 1.8 +/- 0.5 for TKR and 1.8 +/- 0.6 for THR. The use of rescue therapy in the rehabilitation guard was correlated with the mean NRS pain and the maximum NRS pain. A very good control of pain with the perioperative anesthetic protocol and pain treatment protocol in use was obtained. PMID- 30290605 TI - Prognostic role of platelet to lymphocyte ratio in prostate cancer: A meta analysis. AB - BACKGROUND: Recently, the prognostic value of the platelet-to-lymphocyte ratio (PLR) has been identified in multiple cancers. However, the prognostic significance of the PLR in prostate cancer (PCa) remains conflicting. We therefore searched relevant studies and conducted a meta-analysis. METHODS: Papers from the databases of PubMed, Web of Science, and the Cochrane Library were retrieved. Six studies comprising 1324 patients were included. RESULTS: The pooled analysis demonstrated that an elevated PLR predicted poor overall survival (OS; HR = 1.85, 95% CI = 1.51-2.25, P < .001) and disease-free survival (DFS; HR = 1.4, 95% CI = 1.1-1.79, P = .007). Subgroup analyses showed that the PLR remained a significant prognostic factor for OS irrespective of ethnicity, tumor stage, or cut-off value. The PLR was an indicator of poor DFS in Asian patients, but not in Caucasian patients. No significant publication bias was detected. CONCLUSION: This meta-analysis showed that a high PLR was correlated with poor DFS and OS in patients with prostate cancer. Due to this meta-analysis being derived from a few studies, the results should be validated in clinical practice. PMID- 30290607 TI - Winged scapula caused by dorsal scapular neuropathy combined with suprascapular neuropathy: A case report. AB - RATIONALE: Scapular winging is caused by neuromuscular dysfunction of shoulder stabilizer muscles. Clinically, a winged scapula can be easily diagnosed by typical physical findings. We report a case of atypical winged scapula caused by dorsal scapular neuropathy combined with suprascapular neuropathy, which has rarely been reported. PATIENT CONCERNS: A 25-year-old right-handed male was admitted to the clinic due to right arm weakness for 1 year. On physical examination, right winged scapula with medially rotated inferior angle was observed on flexion. DIAGNOSES: Under the diagnostic impression of a winged scapula due to long thoracic nerve injury based on physical examination, electrodiagnostic study was performed. However, the results showed right dorsal scapular neuropathy combined with suprascapular neuropathy. INTERVENTIONS: Neck and right shoulder MRI were also performed to rule out other causes of winged scapula, but these showed only a partial thickness tear of the rotator cuff tendon. The patient received rehabilitation. OUTCOMES: The symptoms have not improved. LESSONS: In this case, combined suprascapular neuropathy might contribute to scapular winging and can confuse the diagnosis of winged scapula based on physical findings. This is the first report that indicates suprascapular neuropathy as a contributing factor of scapular winging. PMID- 30290606 TI - Phosphaturic mesenchymal tumor and related wound problem. AB - INTRODUCTION: Phosphaturic mesenchymal tumor mixed connective tissue type (PMT/MCT) is the most common type (up to 90%) of phosphaturic mesenchymal tumor (PMT), a rare clinicopathologic entity. Besides overproduction of fibroblast growth factor 23 (FGF23), there is a big variation of immunohistochemical characteristic across types of PMT, which makes it difficult to obtain an early diagnosis of PMT/MCT. As a benign tumor, PMT/MCT usually happens in subcutaneous tissues and leads to nonhealing of wound. A complete excision of PMT/MCT facilitates wound healing. CONCLUSIONS: Review of the existing evidence indicates that early diagnosis of PMT/MCT is critically important when treating PMT/MCT wound. Hence standardization of early diagnosis for PMT/MCT is mandated. PMID- 30290608 TI - Everolimus-induced pulmonary toxicity: Findings on 18F-FDG PET/CT imaging. AB - The everolimus-exemestane combination is indicated in advanced breast cancer treatment and usually well tolerated. The objective of the study was to determine the frequency of everolimus lung side effects and investigate their imaging characteristics on positron emission tomography with 18F-fluoro-deoxy-glucose combined with computerized tomography (F-FDG PET/CT).Our single-center retrospective descriptive study systematically included all patients with metastatic breast cancer treated by this combination (n = 29 representing 57 F FDG PET/CT). Number of segments involved was quantified. Maximum standardized uptake value (SUVmax), average standardized uptake value (SUVmean), metabolic target volume (MTV), and total lesion glycolysis (TLG) were measured. Severe pneumopathy was studied by subgroup analysis.Pleuroparenchymal anomalies rate detected on F-FDG PET/CT was 62%. Alveolar-interstitial lesions were mainly observed (89%) and affected 2.8 segments (0.5-11.5) with a median of 2 segments. S7 and S10 were the most involved segments with SUVmax 3.9 (1.3-8.8) and SUVmean 2.2 (0.7-4.9). Statistically significant difference (P = .02) was found with number of segment involved to characterize severe pneumopathy (average of 6.3 segments [2.5-11.5] vs 1.9 segments [0.5-8] for interstitial lung disease) but not with SUVmax, SUVmean, MTV, TLG (P = .14, 0.22, 0.22, and 0.17, respectively).The F-FDG PET/CT could highlight pulmonary everolimus side effects, with a typical imaging pattern: alveolar-interstitial opacities associated with moderate uptake, more or less extensive, mainly affecting the lower lobes. Rarely, a pseudotumoral aspect may be detected, corresponding to a pitfall. MTV or TLG showed a tendency to differentiate severe pneumopathy vs interstitial lung disease but no statistically significant differences was observed contrarily to the number of segments involved. Further studies are necessary to determine if the F-FDG PET/CT could early predict adverse effects of mTOR inhibitors. PMID- 30290609 TI - ICAM-1 gene rs5498 polymorphism decreases the risk of coronary artery disease. AB - BACKGROUND: Many studies investigated the association between intercellular adhesion molecule 1 (ICAM-1) gene rs5498 polymorphism and the risk of coronary artery disease (CAD). However, the results were inconsistent. METHODS: To clarify convincing association, we conducted a comprehensive meta-analysis by searching in PubMed, Embase, Web of sciences, Sciences citation index, Google scholar, Cochrane Library, and the CNKI databases. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. RESULTS: A total of 29 case-control studies with 5,494 cases and 6,364 controls for rs5498 polymorphism were included. The studied populations of this meta-analysis included Caucasians and Asians. Meta-analysis showed that rs5498 polymorphism was associated with the decreased risk of CAD. Stratification analysis of ethnicity found that rs5498 polymorphism decreased the risk of CAD among Caucasians, but not among Asians. Stratification by type of CAD revealed that ICAM-1 gene rs5498 polymorphism was also correlated with the decreased risk of myocardial infarction (MI). CONCLUSION: In conclusion, this meta-analysis indicates that ICAM-1 gene rs5498 polymorphism decreases the risk of CAD. PMID- 30290610 TI - One case report of giant atypical leiomyoma of the ovary. AB - RATIONALE: Ovarian leiomyoma is a rare ovarian tumor that occurs in 20-65 year old women, and is mostly misdiagnosed as malignant tumor. In most reports on this type of tumor, ovarian myoma has a benign histology. Herein,we describe a case of ovarian atypical leiomyoma. PATIENT CONCERNS: The patient is a 58-year-old woman. At the age of 40 years old, the patient underwent hysterectomy due to "hysteromyoma" and secondary anemia. The patient was admitted to our hospital due to palpation of lower abdominal mass and abdominal distention. DIAGNOSES: A mass was revealed at the left uterine appendage by pelvic ultrasound and CT.Pathology and immunohistochemistry confirmed the diagnosis of the left ovarian atypical leiomyoma. INTERVENTIONS: Pelvic cavity resection and right adnexectomy were performed during laparotomy for the patient. OUTCOMES: Without radiotherapy or chemotherapy, there were no signs of tumor recurrence in a 9-month follow-up period. LESSONS: When a solid mass appears in ovarian tissues, ovarian leiomyoma should be considered. Patients with this type of tumor are mostly asymptomatic. Preoperative diagnosis was difficult, intraoperative frozen section would be helpful for determining the scope of the surgery, and the correct diagnosis was made by identifying the properties of smooth muscles through postoperative pathology and immunohistochemistry. PMID- 30290611 TI - Effect of perioperative oral management on the prevention of surgical site infection after colorectal cancer surgery: A multicenter retrospective analysis of 698 patients via analysis of covariance using propensity score. AB - Surgical site infection (SSI) is 1 of the frequent postoperative complications after colorectal cancer surgery. Oral health care has been reported to reduce the risk of SSI or postoperative pneumonia in oral, esophageal, and lung cancer surgeries. The purpose of the study was to investigate the preventive effect of perioperative oral management on the development of SSI after a major colorectal cancer surgery.The medical records of 698 patients who underwent colorectal cancer surgery at 2 hospitals in Japan were reviewed. Among these patients, 563 patients received perioperative oral management (oral management group) and 135 did not (control group). Various demographic, cancer-related, and treatment related variables including perioperative oral management intervention and the occurrence of SSI were investigated. The relationship between each variable and the occurrence of SSI was examined via univariate and multivariate analyses using Fisher exact test, 1-way analysis of variance (ANOVA), and logistic regression. The occurrence of SSI in the 2 groups was evaluated via logistic regression using propensity score as a covariate. The difference in mean postoperative hospital stay between the oral management and control groups was analyzed using Student's t test.SSI occurred in 68 (9.7%) of the 698 patients. Multivariate analysis showed that operation time, blood loss, and perioperative oral management were significantly correlated with the development of SSI. However, after the propensity score analysis, not receiving perioperative oral management also became a significant risk factor for SSI. The odds ratio of the oral management group was 0.484 (P = .014; 95% confidence interval: 0.272-0.862). Mean postoperative hospital stay was significantly shorter in the oral management group than in the control group.Perioperative oral management reduces the risk of SSI after colorectal cancer surgery and shortens postoperative hospital stay. PMID- 30290612 TI - Synchronous hepatocellular carcinoma and lymphoepithelioma-like carcinoma arising from 2 different sites of the liver: A case report. AB - RATIONALE: Most cases of primary liver cancer involve hepatocellular carcinoma (HCC). Lymphoepithelioma-like carcinoma (LELC) is defined as a tumor composed of undifferentiated epithelial cells with a prominent lymphoid infiltrate, which is rarely reported. Lymphoepithelioma-like HCC (LEL-HCC) is an uncommon variant of HCC, having an unclear process of development. Here, we report the first case involving simultaneous HCC and LEL-HCC. PATIENT CONCERNS: A 77-year-old female was accidentally found to have a hypoechoic hepatic nodule via an abdominal ultrasound during a health examination. Abdominal computed tomography scan revealed 2 hepatic nodules with arterial phase enhancement and washout in the late phase. DIAGNOSES: We diagnosed the case with 2 distinct liver nodules, HCC and LEL-HCC. INTERVENTIONS: With suspicion of HCC, tumor resection (liver segments 4 and 5) was then performed. Histopathological examination of tumor 1 showed a moderately differentiated HCC and tumor 2 demonstrated a LEL-HCC. Immunohistochemically, the cells of tumor 2 were immunoreactive for cytokeratin (CK), CK7, and CK19. Epstein-Barr virus encoding small RNA (EBER) in situ hybridization results were negative. OUTCOMES: Six months after resection, intrahepatic tumor recurrence was noted. Radiofrequency ablation was conducted. LESSONS: This is an interesting case providing circumstantial evidence of simultaneous development of HCC and LEL-HCC in distinct nodules of the liver with a background of chronic hepatitis B virus infection. PMID- 30290613 TI - Splenic cystic lymphangiomatosis in association with omental varices and portal hypertension: A case report. AB - RATIONAL: Lymphangiomatosis is rare and benign, and slowly proliferating lymphatic vessels of unknown etiology and visceral lymphangiomatosis involving the spleen is rare. Since lymphangiomatosis may be asymptomatic or present as a sense of fullness, splenic cystic lymphangiomatosis is a disease of little concern. PATIENT CONCERNS: A 34-year-old woman suffering from progressive epigastric fullness after oral intake for two weeks. DIAGNOSES: Physical examination showed a palpable mass which was more than 10 cm in size over the left hypochondrium. An abdominal computed tomography disclosed marked splenomegaly with multiple cystic lesions in the spleen, causing external compression with right-sided deviation of the adjacent organs and varices in the upper abdomen. Esophagogastroduodenoscopy revealed portal hypertensive gastropathy. INTERVENTIONS: Conventional total splenectomy was performed in this patient because of an enlarged spleen and unknown etiology, preoperatively. Upon surgery, splenomegaly with polycystic content and varicose vessels over the omentum were noted. Autologous spleen transplantation was not performed because of limited orthotopic and vascularized spleen. OUTCOMES: The patient is doing well 18 months after splenectomy. LESSONS: This was a rare case presenting with splenic cystic lymphangiomatosis in association with omental varices and portal hypertension. Splenic cystic lymphangiomatosis should be considered in the differential diagnosis of patients with a palpable painless mass over the left hypochondrium. PMID- 30290614 TI - Herbal medicine Yukgunja-tang for functional dyspepsia protocol for a systematic review of randomized controlled trials. AB - BACKGROUND: Functional dyspepsia (FD) is a common functional gastrointestinal disorder characterized by recurrent dyspeptic symptoms. Yukgunja-tang (YGT) is a traditional herbal formula that has been used for treating FD. This systematic review protocol aims to provide a guideline for investigating the efficacy and safety of YGT in the treatment of FD. METHODS: The following databases will be searched from their inception until July 2018: Medline (via PubMed), EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), Allied and Complementary Medicine Database (AMED), KoreaMed, National Digital Science Library (NDSL), Korean Medical Database (KMbase), Oriental Medicine Advanced Searching Integrated System (OASIS), Korean Studies information Service System (KISS), China National Knowledge Infrastructure Database (CNKI), and Citation Information by Nii (CiNii). Randomized controlled trials (RCTs) that used YGT or modified YGT for treating FD will be included. The control groups in these RCTs will include placebo, no-treatment waiting, and conventional western medicine groups. Trials testing YGT as an adjunct to western medicine for synergistic effect will also be included. The main outcome will be the total clinical efficacy rate. Data extraction and risk of bias assessment will be performed by two independent assessors. RevMan V.5.3 will be used for data analysis. RESULTS: This study will provide a high-quality synthesis of current evidence of YGT for FD from several aspects including dyspepsia-related symptoms, quality of life and adverse events. CONCLUSION: The conclusion of our systematic review will provide evidence to judge whether YGT is an effective intervention for patient with FD. ETHICS AND DISSEMINATION: The protocol does not need ethics approval because identifying information of the participants will not be revealed. The systematic review will be published in a peer-reviewed journal and disseminated electronically and in print. TRIAL REGISTRATION NUMBER: PROSPERO CRD42018090139. PMID- 30290615 TI - Early post-operative cognitive dysfunction after closed-loop versus manual target controlled-infusion of propofol and remifentanil in patients undergoing elective major non-cardiac surgery: Protocol of the randomized controlled single-blind POCD-ELA trial. AB - INTRODUCTION: Post-operative cognitive dysfunction (POCD) is frequent in patients older than 60 years undergoing major non-cardiac surgery, and increases both morbidity and mortality. Anesthetic drugs may exert neurotoxic effects and contribute to the genesis of POCD. The hypothesis of the POCD-ELA trial was that closed-loop target-controlled infusion of propofol and remifentanil could reduce the occurrence of POCD by decreasing the risk of excessive depth of anesthesia and the dose of anesthetic drugs. METHODS AND ANALYSIS: We designed a single center, single-blind, randomized, controlled, parallel trial and aim to include 204 patients aged >60 years undergoing elective major non-cardiac surgery. Patients will be randomized to receive closed-loop versus manual target controlled infusion of propofol and remifentanil guided by bispectral index monitoring. Cognitive assessment will be performed the day before surgery (baseline) and within 72 hours after surgery, using a battery of validated neuropsychological tests. The primary outcome is the incidence of POCD within 72 hours after surgery. POCD is defined as a Z-score value > 1.96 for at least 2 different tests or a Z-score composite value >1.96. The calculation of the Z score is based on data from an age-matched control population who did not undergo surgery or general anesthesia. ETHICS AND DISSEMINATION: This study was approved by the Ethics Committee (Comite de Protection des Personnes Est-II) and authorized by the French Health Products Agency (Agence Nationale de Securite des Medicaments, Saint-Denis, France). The University Hospital of Besancon is the trial sponsor and the holder of all data and publication rights. Results of the study will be submitted for publication in a peer-review international medical journal and for presentation in abstract (oral or poster) in international peer reviewed congresses. REGISTRATION: The trial is registered with ClinicalTrials.gov (Identifier: NCT02841423, principal investigator: Prof Emmanuel Samain, date of registration: July 22, 2016). Last amendment of protocol: version 8.0 April 2018. PMID- 30290616 TI - Efficacy and safety of PDE5 inhibitors in the treatment of diabetes mellitus erectile dysfunction: Protocol for a systematic review. AB - INTRODUCTION: Diabetes mellitus erectile dysfunction (DMED) is a common complication of long-term hyperglycemia. With the increasing of diabetic patients, the number of DMED patients is gradually growing up, which has a serious impact on the quality of life of patients. PDE5 inhibitors have good clinical efficacy in DMED patients. This study is designed to evaluate the efficacy and safety of PDE5 inhibitors in DMED patients. METHODS AND ANALYSIS: We will systematically search all randomized controlled trials (RCTs) by electronic and manual search. Electronic retrieval of the database includes Pubmed, EMBASE, The Cochrane Library, the Chinese BioMedical Literature Database, the China National Knowledge Infrastructure (CNKI), the China Science and Technology Journal database (VIP) and the Wanfang database. Manual search will retrieve gray literature, including dissertations, ongoing experiments, grey literature, conference and unpublished documents. We use the IIEF-5 scale as the primary outcome of DMED. We also need to pay attention to the following outcomes: the sexual satisfaction of patients and their partners, like IIEF Q3 Q4; SEP 2, 3; GAQ. More importantly, the adverse reactions of patients during medication will also be taken seriously. Two reviewers will independently read the articles, extract the data information, and give the assessment of risk of bias. Data analysis will be used the special software like RevMan (version 5.3.5), ENDNOTE X7 and STATA 13. RESULTS: This study will provide a comprehensive assessment based on current evidence of PDE5 inhibitors for DMED, especially its impacts on International Index of Erectile Function, the sexual satisfaction of patients and their partners and safety. ETHICS AND DISSEMINATION: This systematic review will evaluate the efficacy and safety of PDE5 inhibitors on DMED. This review does not require ethical approval and will be reported in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: PROSPERO CRD42018095185. PMID- 30290617 TI - The association of polymorphisms in promoter region of MMP2 and MMP9 with recurrent spontaneous abortion risk in Chinese population. AB - This study aimed to reveal the genetic association between polymorphisms in promoter region of matrix metalloproteinase 2 (MMP2) and matrix metalloproteinase 9 (MMP9) and the risk of recurrent spontaneous abortion (RSA) in Chinese population.A total of 129 RSA patients and 116 relative controls were selected and the genotyping of polymorphism was conducted by polymerase chain reaction with sequencing. Genotype distribution of polymorphism in the control group was tested the status of Hardy-Weinberg equilibrium and then, genotype frequencies were compared between the case and control groups by chi-squared test. Odds ratio (OR) with the corresponding 95% confidence interval (95% CI) was computed to express the risk of RSA caused by polymorphism. Moreover, the linkage disequilibrium of polymorphisms in MMP2 was analyzed by Haploview software.CT genotype and T allele of rs243865 in MMP2 were significantly associated with the increased susceptibility to RSA in Chinese population (CT vs. CC: OR = 1.926, 95% CI = 1.101-3.368; T vs. C: OR = 1.751, 95% CI = 1.146-2.676). Similarly, CT genotype carriers of rs3918242 in MMP9 were obviously more in RSA patients than that of the controls (P = .037), which indicated it was associated with the risk of RSA occurrence (OR = 1.760, 95% CI = 1.034-2.995). So was T allele in RSA development (OR = 1.595, 95% CI = 1.061-2.398). Haplotypes C-T and T-C were also the risk factors of RSA (OR = 1.673, 95% CI = 1.103-2.536; OR = 2.171, 95% CI = 1.372-2.436).MMP2 rs243865 and MMP9 rs3918242 polymorphisms are significantly associated with the risk of RSA in Chinese population. PMID- 30290618 TI - Sex hormone therapy's effect on dry eye syndrome in postmenopausal women: A meta analysis of randomized controlled trials. AB - THE PURPOSE OF THE STUDY T: o assess the efficacy of sex hormone therapy in the treatment of dry eye syndrome in postmenopausal women.The following electronic databases were searched without language restrictions: PubMed, Embase, Cochrane, and the Chinese Biomedical Database. Two reviewers collected all the literature, which was searched for relevance in English and Chinese from January 1990 to July 2017. Both of the reviewers screened documents independently, identifying the studies that met the inclusion criteria. Then, the included studies were evaluated, and the data were extracted and conversed dependently. Finally, Review Manager 5.3 (offered by the Cochrane collaboration) was used to complete the meta analysis. An integrated mean difference (MD) with its corresponding 95% confidence interval (CI) was calculated.A total of 358 patients with dry eye were enrolled in 7 randomized controlled trials (RCTs). We observed statistically significant improvements in the Schirmer's test scores (MD, 2.06; 95% CI, 0.74 4.46; I = 97%; P = .006) after sex hormone treatment. However, the scores for tear breakup time (TBUT) (MD, 1.28; 95% CI, -1.03 to 4.68; I = 99%; P = .21) and the ocular comfort index (OCI) (MD, -1.12; 95% CI, -4.42 to 1.98; I = 95%; P = .48) were not improved.This meta-analysis of 7 RCTs suggests that sex hormone therapy may be associated with better Schirmer's test scores. However, no significant differences were detected in the TBUT and OCI test scores. Consequently, sex hormone therapy has a potentially useful role in the effective management of postmenopausal women with dry eye syndrome. PMID- 30290619 TI - Prognostic value of transcranial facial nerve motor-evoked potentials in predicting facial nerve function following cerebellopontine angle tumorectomy. AB - Facial nerve paralysis is a common complication following cerebellopontine angle (CPA) surgery. This study investigated the prognostic value of facial nerve motor evoked potentials (FNMEPs) elicited by transcranial electrical stimulation for facial nerve outcome after CPA tumorectomy.A total of 95 patients were enrolled in this study between January 2014 and January 2016. All these patients underwent CPA tumorectomy (unilateral, n = 95; bilateral, n = 1). Intraoperative FNMEP elicited by transcranial electrical stimulation was recorded. The short- and long term postoperative facial nerve functions were evaluated according to the House Brackmann (HB) scale. The correlation between perioperative changes in the FNMEP stimulus threshold (delta FNMEP = postoperative stimulus threshold level preoperative stimulus threshold level) and postoperative facial nerve functions were analyzed.On the first day postoperatively, the facial nerve function was HB grade I in 67, grade II in 17, grade III in 7, and grade IV in 5 facial nerves. One year postoperatively, the facial nerve function was grade I in 80, grade II in 11, grade III in 3, and grade IV in 2 facial nerves. The delta FNMEP was significantly correlated with the short- and long-term facial nerve function; receiver operating characteristic (ROC) curves yielded a cut-off delta FNMEP value of 30 V (sensitivity, 91.3%; specificity, 98.6%) and 75 V (sensitivity, 100%; specificity, 98.8%) for predicting short- and long-term facial nerve function damage, respectively.FNMEP elicited by transcranial electrical stimulation is an effective and safe approach for predicting facial nerve function in CPA tumorectomy. A high delta FNMEP is a potential indicator for the prediction of postoperative facial nerve damage. PMID- 30290620 TI - 99mTc-MIBI single photon emission computed tomography/computed tomography for the incidental detection of rare parathyroid carcinoma. AB - This study aimed to evaluate the characteristics of parathyroid carcinoma and to validate the diagnostic value of Tc-methoxyisobutylisonitrile (MIBI) single photon emission computed tomography/x-ray computed tomography (SPECT/CT) for differentiating between parathyroid carcinoma and hyperparathyroidism. Four consecutive patients with suspected primary hyperparathyroidism were enrolled in this study and underwent Tc-MIBI SPECT/CT, ultrasonography, enhanced CT, and MRI. Serum parathyroid hormone (PTH) and calcium were measured. All primary and recurrent lesions showed high focal uptake on Tc-MIBI image, whereas metastatic lymph nodes gave false negative results. The serum PTH was 165.14 +/- 90.26 pmol/L, which declined rapidly after surgery. One patient with a persistently high PTH (147.5 pmol/L) after surgery presented with multiple lymphadenopathy in the neck. Higher expression of chromogranin A (CgA) further confirmed parathyroid carcinoma as a rare endocrine tumor. Parathyroid carcinoma is thus usually diagnosed incidentally based on nonspecific multiorgan symptoms of hypercalcemia and hyperparathyroidism. Tc-MIBI SPECT/CT may help to localize the parathyroid carcinoma, while MRI is valuable for detecting metastasis. Serum PTH and CgA serve as circulating biomarkers in parathyroid carcinoma, and raised levels of PTH and CgA together with locoregional lymphadenopathy may indicate parathyroid carcinoma. Further studies are needed. PMID- 30290622 TI - Application of lower limb nerve block combined with slow induction of light general anesthesia and tracheal induction in elderly hip surgery. AB - BACKGROUND: This study aims to evaluate the effectiveness and safety of lower limb nerve block combined with slow induction of light general anesthesia and tracheal intubation in hip surgery in the elderly. METHODS: Thirty elderly patients who underwent hip surgery under the lower limb nerve block were randomly divided into 2 groups: slow induction of light general anesthesia and tracheal intubation group (group M), and laryngeal mask light general anesthesia group (group H). After undergoing total intravenous anesthesia without muscle relaxants, all patients received sciatic nerve, lumbar plexus, and paravertebral nerve blocks. The hemodynamic situations, dosage of anesthetics, time for awakening and extubation (or laryngeal mask removal), and incidence of respiratory adverse reactions in the induction period were recorded. RESULTS: Compared with baseline levels, the difference in mean arterial pressure (MAP) value at each time point after intubation/laryngeal mask removal in both groups was not statistically significant (P > .05). Furthermore, the time for awakening and extubation/laryngeal mask removal, and anesthetic dosage were significantly decreased in group M, when compared with group H (P < .05). For the incidence of adverse reactions, the incidence of poor sealing and hypoxia was significantly lower in group M than in group H (P < .05), and the incidence of sore throat was significantly lower in group H than in group M (P < .05). CONCLUSION: Lower limb nerve block combined with slow induction of light general anesthesia and tracheal intubation was associated with smaller anesthetic dosage, and shorter duration of anesthesia induction and extubation/laryngeal mask after surgery. PMID- 30290621 TI - Genetic polymorphisms of the drug-metabolizing enzyme CYP2J2 in a Tibetan population. AB - As an important metabolic enzyme, it is necessary to investigate the genetic polymorphisms of CYP2J2 among healthy Tibetan individuals. Genetic polymorphisms of CYP2J2 could affect enzyme activity and lead to differences among individual responses to drugs.We sequenced the whole gene of CYP2J2 in 100 unrelated, healthy Tibetan volunteers from the Tibet Autonomous Region and screened for genetic variants in the promoters, introns, exons, and the 3'-UTR regions.We detected 4 novel genetic polymorphisms of the CYP2J2 gene. The allelic frequencies of CYP2D6*1 and *7 were 0.955 and 0.045, respectively. CYP2D6*1/*7 decreased the activity of CYP2J2 and was expressed in 9% of the sample population.Our results provided basic data about CYP2J2 polymorphisms in a Tibetan population, suggested that the enzymatic activities of CYP2J2 might be different within the ethnic group, and offered a theoretical basis for individualized medical treatment and drug genomics studies. PMID- 30290623 TI - Comparison of transcatheter closure, mini-invasive closure, and open-heart surgical repair for treatment of perimembranous ventricular septal defects in children: A PRISMA-compliant network meta-analysis of randomized and observational studies. AB - OBJECTIVE: Our study was aimed to comprehensively compare the relative efficacy, safety, and the cost of transcatheter closure, mini-invasive closure, and open heart surgical repair to treat perimembranous ventricular septal defects (pmVSDs) in children using network meta-analysis method. METHODS: Five databases were systematically searched including Chinese Biomedical Literature Database, China National Knowledge Infrastructure, PubMed, EMBASE.com, and the Cochrane Central Register of Controlled Trials from the starting date of each database to February 2017. Tools for assessing the risk of bias in nonrandomized studies of interventions (ROBINS-I) were used to evaluate the risk of bias in observational studies and Cochrane Handbook version 5.1.0 was used for randomized controlled trials (RCTs). Data were analyzed using R-3.4.0 software and Review Manager 5.2. RESULTS: Three RCTs and 24 observational studies were included in our study. Network meta-analysis result demonstrated that transcatheter closure was the most effective treatment in terms of operative time [standardized mean difference (SMD) = -2.02, 95% confidence interval (CI): -3.92 to -0.12], major complications [odds ratio (OR) = 0.52, 95% CI = 0.30-0.91], ICU stay (SMD = -1.11, 95% CI = 2.13 to -0.08), and hospital stay (SMD = -1.81, 95% CI = -2.24 to -1.39). However, open-heart surgical repair showed a higher success rate of the procedure than transcatheter closure (OR = 0.36, 95% CI = 0.17-0.77).Statistical analysis result demonstrated that transcatheter closure had the best potential to lessen major complications, ICU stay, hospital stay, operative time, and significant residual shunt. CONCLUSIONS: Transcatheter closure has more benefit than mini invasive closure and open-heart surgical repair to treat pmVSDs. PMID- 30290624 TI - Eculizumab in a pregnant patient with laboratory onset of catastrophic antiphospholipid syndrome: A case report. AB - RATIONALE: Hypercoagulability and pregnancy morbidity are hallmarks of the antiphospholipid syndrome (APS). Catastrophic antiphospholipid syndrome (CAPS) is a potentially life-threatening omplication of APS, with widespread acute thrombotic microangiopathy (TMA) that can be precipitated by pregnancy and delivery and result in multiorgan damage. Unrestrained activation of the complement cascade is involved, favoring endothelial activation, tissue factor expression by leukocytes, and platelet aggregation. The complement block, which interrupts this amplification cycle, could prevent CAPS in patients with early TMA who face precipitating events. PATIENT CONCERNS: We present a nulliparous pregnant woman with APS at the 30 week of gestation who has developed thrombocytopenia, intravascular hemolysis, elevated creatinine, proteinuria, and hematuria. DIAGNOSES: These featurs were compatible with the diagnosis of CAPS. Consensually, serum C3 protein levels were rapidly decreasing, reflecting complement consumption. INTERVENTIONS: She was treated with eculizumab, a humanized monoclonal antibody against C5 that prevents the formation of the complement membrane attack complex. OUTCOMES: Laboratory parameters improved and the patient did not develop thrombosis or detectable organ/tissue damage. The patient safely delivered by cesarean section at week 32 of gestation a healthy 1640 g male infant. After 5 days, she received additional eculizumab, with complete resolution of the clinical condition. Low complement activity was detectable in the infant blood for a week after delivery. No infectious complication occurred. LESSONS: Inhibition of the terminal complement activation is safe and might be effective in patients with APS developing early TMA, enabling safe delivery and preventing thrombotic events both in the mother and in the newborn. PMID- 30290625 TI - Bidirectionality of the dentato-rubro-thalamo-cortical tract allows concurrent hypoperfusion in ipsilateral cerebellum and contralateral cerebral hemisphere: A case report. AB - RATIONALE: The brain circulation of the dentato-rubro-thalamo-cortical tract (DRTT) has been reported for decade, but is rarely observed using nuclear medicine imaging tools, to analyze a patient with midbrain hemiatrophy syndrome. We present a case that revealed notable interruption in the middle of the DRTT. Finding out whether the superior cerebellar peduncle of the midbrain was injured was a decisive element for developing bidirectional effect of DRTT. PATIENT CONCERNS: A 34-year-old right-handed female presented with progressive weakness and bradykinesia in the left-sided limbs for about 6 months. She had difficulty with hand dexterity for activities of daily life and general tasks. She reported poor balance during walking and sitting. Muscle strength was 3 in the left hand and 4 in the foot due to atrophy of left limbs. The circumference of 10 cm proximally/distally from the lateral epicondyle of the humerus was 25.7/23.8 cm at right and 24.2/20.8 cm at left in the upper limbs, and 15 cm proximally/distally from the lateral joint space was 42.1/35.0 cm at right and 43/30.8 cm at left in the lower limbs. The brain magnetic resonance imaging study revealed a small-sized right midbrain. DIAGNOSIS: Based on the distinct features of limbs atrophy and the locations of the lesions on the magnetic resonance (MR) imaging, the patient was diagnosed with midbrain hemiatrophy syndrome. INTERVENTIONS: The patient was only willing to accept physical and occupational training programs at our outpatient clinic. OUTCOMES: We utilized serial anatomic and functional neuroimaging of the brain to survey the neurologic deficit. Brain perfusion single-photon emission computed tomography (SPECT) showed hypoperfusion over the left fronto-parietal regions, left anterior temporal region, and left occipital region, and also the left striatum and right cerebellum. Symptoms were gradually recovered with rehabilitation, and he was transferred to a rehabilitation facility on hospital day 40. LESSONS: This is the first report to demonstrate concurrent hypoperfusion of ipsilateral cerebellum and contralateral cerebral hemisphere observed on SPECT images in a case of midbrain hemiatrophy syndrome. In our case, with midbrain hemiatrophy syndrome could be explained as mutual direction effect of DRTT. PMID- 30290626 TI - Lethal neonatal mitochondrial phenotype caused by a novel polymerase subunit gamma mutation: A case report. AB - RATIONALE: Polymerase subunit gamma (POLG) is a gene that codes for the catalytic subunit of the mitochondrial DNA polymerase, which is involved in the replication of mitochondrial DNA. Mutations in these genes are associated with a range of clinical syndromes characterized by secondary mtDNA defect including mtDNA mutation and mtDNA depletion which may culminate in complete failure of energy production (respiratory changes complex 1 defect) as in this case. PATIENT CONCERNS: We herein report a full term Saudi female neonate born to consanguineous parents, who was noticed immediately after birth to have severe hypotonia, poor respiratory effort, and dysmorphic features. She had 3 siblings who died with same clinical scenario in neonatal period. DIAGNOSES: Molecular genetic testing revealed a novel compound heterozygous mutation of POLG gene c.680G>A (p.Arg227Gin) and c.3098C>T (p.Ala1033Val). INTERVENTIONS: The patient remained in neonatal intensive care unit with multidisciplinary team management and was ventilator dependent until she passed away. OUTCOMES: The detected mutation had led to complete failure of energy production (respiratory changes complex 1 defect) until she died at the age of 5 months. LESSONS: Mitochondrial respiratory chain defect should be considered in patients with severe neonatal hypotonia,encephalopathy, and respiratory failure especially in highly consanguineous population. PMID- 30290627 TI - Comparison of blind intubation via supraglottic airway devices versus standard intubation during different airway emergency scenarios in inexperienced hand: Randomized, crossover manikin trial. AB - BACKGROUND: Securing the airway and enabling adequate oxygenation and ventilation is essential during cardiopulmonary resuscitation (CPR). The aim of the study was to evaluate the success rate of blind intubation via the I-Gel and the Air-Q compared with direct laryngoscopy guided endotracheal intubation by inexperienced physician and to measure time to successful intubation. METHODS: The study was designed as a randomized, cross-over simulation study. A total of 134 physicians, from specialties other than Anesthesia or Emergency Medicine, who considered themselves skilled in endotracheal intubation but who have never used any kind of supraglottic airway device performed blind intubation via the I-Gel and Air-Q and direct laryngoscopy guided endotracheal intubation in 3 randomized scenarios: normal airway without chest compression during intubation attempt; normal airway with continuous chest compression during intubation attempt; difficult airway with continuous chest compression. RESULTS: Scenario A: Success rate with initial intubation attempt was 72% for endotracheal intubation, 75% in Air-Q, and 81% in I-Gel. Time to endotracheal intubation and ease of intubation was comparable with all 3 airway devices used. Scenario B: Success rate with the initial intubation attempt was 42% for endotracheal intubation, compared with 75% in Air-Q and 80% in I-Gel. Time for endotracheal intubation was significantly prolonged in endotracheal intubation (42 seconds, 35-49), compared with Air-Q (21 seconds, 18 32) and I-Gel (19 seconds, 17-27). Scenario C: The success rate with the initial intubation attempt was 23% in endotracheal intubation, compared with 65% in Air-Q and 74% in I-Gel. Time to intubation was comparable with both supraglottic airway devices (20 vs 22 seconds) but was significantly shorter compared with endotracheal intubation (50 seconds, P < .001). CONCLUSIONS: Less to moderately experienced providers are able to perform endotracheal intubation in easy airways but fail during ongoing chest compressions and simulated difficult airway. Consequently, less to moderately experienced providers should refrain from endotracheal intubation during ongoing chest compressions during CPR and in expected difficult airways. Supraglottic airway devices are reliable alternatives and blind intubation through these devices is a valuable airway management strategy. PMID- 30290628 TI - Musculoskeletal complaints in healthcare personnel in hospital: An interdepartmental, cross-sectional comparison. AB - The objective of this study is to investigate musculoskeletal complaints (MSCs) in healthcare workers (HCWs) in 3 community hospital-based departments [internal medicine (IM), general surgery (GS), and emergency department (ED)] and its effects on the quality of work life (QWL) of hospital HCW.This prospective cross sectional study was performed in the 700-bed community training hospital. All HCW staffed in 3 departments (IM, GS, ED) of the hospital were asked to respond to items in the study data sheet. Enrolled personnel were inquired about their demographic data, work history and schedule, and medical history. The 16-item Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) Turkish version was applied to evaluate MSC. A total of 216 HCW constituted the study sample and demographic characteristics, history, and clinical findings were analyzed.Among all, 103 personnel (47.7%) were women (n = 42, 41.1% in physicians, n = 57, 87.6% in nurses and n = 4, 8% in other HCW) (P = .000). A total of 173 personnel (79.7%) reported MSC in some part of their bodies. Female personnel had MSC significantly more commonly than males (chi-square = 40.7, P = .000). Numbers and percentages of the personnel with MSC in 3 departments (IM, GS, ED) were 51/61, 52/65, and 70/90, respectively (P = .67). Total QWL score of those without MSC was significantly higher than others (74.7 + -12 vs 63.2 + -15, respectively; t test, P = .000). Total frequency score of MSC as elicited via CMDQ was significantly higher in those without MSC compared to the others (8.1 + -7.6 vs 0.1 + -0.6, respectively, t test, P = .000).Female sex, high-income, university graduation, being a nurse or a physician, and older age impose risk for HCW in hospital with respect to having MSC. Presence of MSC affects QWL negatively. PMID- 30290629 TI - Effect of gel seat cushion on chronic low back pain in occupational drivers: A double-blind randomized controlled trial. AB - BACKGROUND: Low back pain (LBP) is an exceedingly common medical condition that results in significant medical and social burden. Sitting for a long period is a common aggravating factor for LBP. Although seat cushion is known to promote comfort, relieve pressure, and correct posture, its effect on chronic LBP has not yet been investigated. This study aimed to evaluate the clinical effect of gel seat cushion on chronic LBP in occupational drivers. METHODS: Occupational drivers with chronic LBP lasting for >6 months were recruited. Subjects were double-blinded, randomly assigned to 2 groups (gel and foam cushion groups), and instructed to use the provided cushions while driving. Pain threshold and tissue hardness were measured at tender points using a digital algometer. Numeric pain intensity scale (NPIS), Roland-Morris Disability Questionnaire (RMDQ), and Oswestry Disability Index (ODI) were used to analyze the primary endpoint, whereas the Beck Depression Inventory and Short Form-6D were used for the secondary endpoint. RESULTS: Of 80 enrolled subjects, 75 (gel cushion group, 40; foam cushion group, 35) were included for analysis. Both groups showed significant improvement in NPIS and ODI scores following cushion use. Results for Beck Depression Inventory and Short Form-6D scores indicated that gel cushion use was significantly helpful. Change in NPIS score was significantly greater in the gel cushion group than in the foam cushion group. CONCLUSION: Gel cushion use may be effective in relieving LBP in occupational drivers seated for a long period compared with foam cushion use. PMID- 30290630 TI - Curative-intent radiotherapy in patients with oligometastatic lesions from colorectal cancer: A single-center study. AB - The purpose of the present study was to investigate the efficacy and safety of radiotherapy for patients with oligometastases from colorectal cancer (CRC).This was a retrospective cross-sectional study. Patients with liver and/or lung oligometastatic lesions from CRC treated with curative-intent radiotherapy in West China Hospital, Sichuan University, between 2009 and 2013 were included. Radiotherapy modality included 3-dimensional conformal radiation therapy (3D CRT), intensity-modulated radiation therapy (IMRT), and stereotactic body radiation therapy (SBRT); simultaneous chemotherapies along with radiotherapy of metastasis were allowed. Overall survival (OS) and progression-free survival (PFS) were calculated using the Kaplan-Meier method. Local control (LC) rates, toxicities, and factors of prognostic significance were also assessed.A total of 40 CRC patients with 57 liver and/or lung oligometastatic lesions were included. Most of the patients (95%) had received at least 1 line of previous systemic chemotherapy. Among them, 19 patients with 26 lesions received 3D-CRT with a median dose of 51.5 Gy in 16.1 fractions, 7 patients with 11 lesions received IMRT with a median dose of 49.3 Gy in 10.4 fractions, and 14 patients with 20 lesions received SBRT with a median dose of 56.4 Gy in 6.7 fractions, respectively. The median follow-up time was 34 months (range, 9-86 months). Median OS and PFS for patients were 30.0 months [95% confidence interval (95% CI), 21.3-38.7] and 11.0 months (95% CI, 9-13), respectively. One, 3, and 5 years' LC rates for metastasis were 63.2%, 24.6%, and 16.9%, respectively. In subgroup analysis, patients with metachronous metastases had longer OS (median, 41.0 months; 95% CI, 33.3-48.7) than patients with synchronous lesions (median, 17.0 months; 95% CI, 7.4-26.6, P = .001). All patients tolerated the radiation treatment well, and there was no treatment-related death. Multivariate analysis showed that number of metastasis lesions and simultaneous liver and lung metastases were potential survival predictors.The study demonstrated that curative radiotherapy might be a tolerable and potential alternative for the treatment of patients with liver and/or lung oligometastases from CRC, and patients with metachronous lesions might have better survival than those with synchronous lesions when treated with curative-intent radiotherapy.

AB - To report our preliminary experience with cerebral fetal magnetic resonance imaging (MRI) with a 3 Tesla (3T) scanner. We assessed feasibility, time of acquisition, and possibility to establish a diagnosis.Fifty-nine pregnant women had fetal MRI performed during the third trimester of pregnancy due to clinical or sonography concern of a central nervous system anomaly. No fetal or maternal sedation was used. The MRI protocol consisted of T2 turbo-spin-echo images in 3 planes of space. No T1-weighted images were performed. All images were analyzed by 2 pediatric neuroradiologists, who evaluated spatial resolution, artifacts, time of acquisition, and possibility to establish a diagnosis suspected by sonography.Examinations were performed safely for all patients. The images required longer time of acquisition (approximately 75 seconds for each plane in the space). The specific absorption rate was not exceeded in any fetus. Cerebral fetal MRI was normal in 22 cases. The spectrum of diagnostics included isolated ventriculomegaly, posterior fossa malformation, corpus callosum malformation, gyration anomalies, craniosynostosis, tuberous sclerosis, microcephaly, external hydrocephaly, midline arachnoid cyst, cerebral lesions, and persistent hyperplastic primitive vitreous.In our series, 3 T MRI of fetal brain was feasible and able to establish a diagnosis but required longer time of acquisition. PMID- 30290632 TI - Long-term follow-up of fibular graft for the reconstruction of bone defects. AB - The use of fibular graft for the reconstruction of bone defects has been demonstrated to be a reliable method. The aim of this study was to assess the clinical outcome of graft union, functional outcome (hypertrophy of the graft bones) and complications of both non-vascularized and vascularized grafts.From 1981 to 2015, 10 patients were treated using non-vascularized fibular graft or free vascularized fibular graft. The outcomes were bony union time, graft hypertrophy and complications based on radiograph and functional outcomes according to the Musculoskeletal Tumor Society (MSTS) score. Mobility of the ankle at the donor site was evaluated using the Kofoed ankle score system.This study included 10 patients with an average follow-up of 6.8 years. The union rate for all patients was 100%. The mean union time was 21.3 weeks for vascularized fibular grafts and 30.5 weeks for non-vascularized fibular grafts (P = .310). There was a significant difference between the upper limbs and the lower limbs regarding hypertrophy of the grafts in 5 patients (P = .003). The mean MSTS score in 10 patients was 84% (range 53%-97%). Stress fracture of the graft occurred in 1 patient. Donor site complications, including valgus deformity and length discrepancy, between 2 legs occurred in 2 patients who were under 18 years of age at the time of operation (P = .114). The mean Kofoed score was 96.8 (range 88 100).A greater increase in hypertrophy of grafts was observed with reconstruction in the lower limbs. There was no difference in MSTS score between these 2 types of grafts. Children were more likely to experience the valgus deformity at the donor site after harvesting the fibula. Keeping at least the distal 1/4 of the fibula intact during the surgery is a valid means of ensuring ankle stability at the donor site, and children should be considered for prophylactic distal tibiofibular synostosis creation to prevent the valgus deformity of the ankle at the donor site. PMID- 30290633 TI - Neck xanthogranuloma mimicking malignancy in a patient with diabetes mellitus: A case report and literature review. AB - RATIONALE: Xanthogranulomatous inflammation (XGI) is a rare inflammatory process, which mostly affects the kidney and gallbladder. It usually simulates an aggressive neoplastic process. Occurrences in the neck are extremely rare and would usually be associated with a preexisting cyst or glandular tissues. PATIENT CONCERNS: A 49-year-old diabetic patient presented with a right painful neck mass for a week. The pretreatment computed tomography (CT) imaging with contrast demonstrated a huge ill-defined heterogeneous-enhanced lesion abutting surrounding musculatures and great vessels. Both fine needle aspiration (FNA) and ultrasound-guided core biopsy of the neck mass showed inflammatory cells only. DIAGNOSES: Histologic evaluation found granulation tissue with histiocytes and occasional Touton giant cells confirming the diagnosis of xanthogranuloma. INTERVENTIONS: Open excisional biopsy demonstrated a yellowish mass-like lesion with abscess inside. OUTCOMES: The patient recovered from the disease without posttreatment comorbidities. LESSONS: This case highlights the need for physicians to maintain awareness of this clinical entity and delayed- or overtreatment should be avoided in these patients due to preoperative ambiguous diagnosis. PMID- 30290634 TI - Selection of pancreaticojejunostomy technique after pancreaticoduodenectomy: duct to-mucosa anastomosis is not better than invagination anastomosis: A meta analysis. AB - BACKGROUND: One of the most clinically significant current discussions is the optimal pancreaticojejunostomy (PJ) technique for pancreaticoduodenectomy (PD). We performed a meta-analysis to compare duct-to-mucosa and invagination techniques for pancreatic anastomosis after PD. METHODS: A systematic search of PubMed, Embase, Web of Science, the Cochrane Central Library, and ClinicalTrials.gov up to June 1, 2018 was performed. Randomized controlled trials (RCTs) comparing duct-to-mucosa versus invagination PJ were included. Statistical analysis was performed using RevMan 5.3 software. RESULTS: Eight RCTs involving 1099 patients were included in the meta-analysis. The rate of postoperative pancreatic fistula (POPF) was not significantly different between the duct-to mucosa PJ (110/547, 20.10%) and invagination PJ (98/552, 17.75%) groups in all 8 studies (risk ratio, 1.13; 95% CI, 0.89-1.44; P = .31). The subgroup analysis using the International Study Group on Pancreatic Fistula criteria showed no significant difference in POPF between duct-to-mucosa PJ (97/372, 26.08%) and invagination PJ (78/377, 20.68%). No significant difference in clinically relevant POPF (CR-POPF) was found between the 2 groups (55/372 vs 40/377, P = .38). Additionally, no significant differences in delayed gastric emptying, post pancreatectomy hemorrhage, reoperation, operation time, or length of stay were found between the 2 groups. The overall morbidity and mortality rates were not significantly different between the 2 groups. CONCLUSION: The duct-to-mucosa technique seems no better than the invagination technique for pancreatic anastomosis after PD in terms of POPF, CR-POPF, and other main complications. Further studies on this topic are therefore recommended. PMID- 30290635 TI - Acupotomy therapy for lumbar disc herniation: Protocol for a systematic review and meta-analysis. AB - BACKGROUND: Lumbar disc herniation (LDH) is a clinically common degenerative spinal disease that adversely affects patients' quality of life and work ability. Although several articles have reported that acupotomy can improve the clinical symptoms of LDH, the efficiency of acupotomy has not been scientifically or methodically evaluated. The primary objective of this study is to evaluate and synthesize evidence on the effectiveness and safety of acupotomy therapy in patients with LDH. METHOD: We plan to search eight English and Chinese electronic databases, including the Web of Science, Cochrane Library, PubMed, EMBASE, SinoMed, Wanfang, China Science and Technology Journal (VIP), and China National Knowledge Infrastructure (CNKI) databases, for potentially eligible studies. Randomized controlled trials (RCTs) on acupotomy treatment in LDH patients will be searched for independently by 2 reviewers in the databases from their inception to August 2018. We will combine data from clinically homogenous studies in a fixed effect meta-analysis using RevManV.5.3.5, and the evidence level will be assessed by using the method for Grading of Recommendations Assessment, Development, and Evaluation (GRADE). RESULTS: This systematic review and meta analysis will use high-quality evidence-based medicine to assess the efficacy and safety of acupotomy therapy in LDH. CONCLUSION: This study protocol will provide strong evidence to determine whether acupotomy therapy is an effective and safe intervention for patients with LDH. PMID- 30290636 TI - Blood homocysteine levels could predict major adverse cardiac events in patients with acute coronary syndrome: A STROBE-compliant observational study. AB - The Global Registry of Acute Coronary Events (GRACE) risk score independently predicts major adverse cardiac events (MACEs) in patients with acute coronary syndrome (ACS). This study aims to evaluate whether the level of plasma homocysteine in addition to the GRACE score enhances the predictive value for MACEs in patients with acute coronary syndrome.A total of 361 patients with ACS evaluated at our hospital were included in the study and tested for blood homocysteine levels. We recorded 40 (11.1%) instances of MACE during a median follow-up of 43.3 months (quartile 40.6-44.4 months), including 29 cases (8.0%) of all-cause death and 11 cases (3.1%) of nonfatal myocardial infarction.The GRACE score was significantly associated with homocysteine levels, and multivariate Cox regression analysis showed that both the GRACE risk score and homocysteine content were independent predictors of MACEs (HR 2.63; 95% confidence interval (CI) 1.54 to 4.49; P < .001 and 2.27; 1.06 to 4.86; P = .035, respectively). Moreover, meta-analysis showed that as the homocysteine level increased, the incidence of MACEs also increased (log-rank 8.41; P = .015). GRACE scores adjusted by homocysteine level increased the area under the curve (AUC) from 0.78 to 0.83 (P = 0.006).Blood homocysteine levels are significantly associated with the GRACE risk score, and using both parameters can further improve risk stratification in patients with acute coronary syndrome. PMID- 30290637 TI - Therapeutic outcome of spinal implant infections caused by Staphylococcus aureus: A retrospective observational study. AB - Spinal implant infection is a rare but significant complication of spinal fusion surgery, and the most common pathogen is Staphylococcus aureus. It is difficult to treat due to this pathogen's biofilm-forming ability and antibiotic resistance. We evaluated the therapeutic outcome of treatments for S aureus spinal implant infections. We retrospectively reviewed all patients with S aureus spinal implant infections at 11 tertiary-care hospitals over a 9-year period. Parameters predictive of treatment failure and recurrence were analyzed by Cox regression. Of the 102 patients with infections, 76 (75%) were caused by methicillin-resistant S aureus (MRSA) and 51 (50%) were late-onset infections. In all, 83 (81%) patients were managed by debridement, antibiotics, and implant retention (DAIR) and 19 (19%) had their implants removed. The median duration of all antibiotic therapies was 52 days. During a median follow-up period of 32 months, treatment failure occurred in 37 (36%) cases. The median time to treatment failure was 113 days, being <1 year in 30 (81%) patients. DAIR (adjusted hazard ratio [aHR], 6.27; P = .01) and MRSA infection (aHR, 4.07; P = .009) were independently associated with treatment failure. Rifampin-based combination treatments exhibited independent protective effects on recurrence (aHR, 0.23; P = .02). In conclusion, among patients with S aureus spinal implant infections, MRSA and DAIR were independent risk factors for treatment failure, and these risk factors were present in the majority of patients. In this difficult-to-treat population, the overall treatment failure rate was 36%; rifampin may improve the outcomes of patients with S aureus spinal implant infections. PMID- 30290638 TI - Rivaroxaban improves hidden blood loss, blood transfusion rate and reduces swelling of the knee joint in knee osteoarthritis patients after total knee replacement. AB - Osteoarthritis (OA) is the third most common diagnosis made by general practitioners in older patients. The purpose of the current study is to investigate effects rivaroxaban had on both hidden blood loss and blood transfusion rate (BTR) in patients with knee OA (KOA) after going through a total knee replacement (TKR).Between the time periods of December 2011 up until January 2015, a total of 235 patients underwent TKR and were selected to be assigned to either the rivaroxaban or nonanticoagulant groups. Coagulation function indexes before surgery and following administration of rivaroxaban, total blood loss, hidden blood loss, dominant blood loss, blood transfusion volume, hemoglobin reduction, degree of postoperative pain (visual analogue scale), the degree of knee swelling, and range of motion following surgery were all recorded. Hospital for special surgery (HSS) scores offered an objective evaluation for the knee joint functions before surgery at the intervals of 2 weeks and after surgery at intervals of 3 months, 6 months, 12 months, and 24 months.Patients in the rivaroxaban group had shown a higher hidden blood loss, as well as a higher BTR, compared to those involved in the nonanticoagulant group. BTR was found to have been 49.59% in the rivaroxaban group, and 35.09% for the nonanticoagulant group. Patients in the rivaroxaban group had lower degrees of knee swelling than those involved in the nonanticoagulant group. There was no deep vein thrombosis (DVT) detected in the rivaroxaban group, whereas 5 DVT cases were detected in the nonanticoagulant group. In the rivaroxaban group, the HSS scores of the knee joint functions were remarkably higher at the 2-week mark in succession to the surgery than those involved with the nonanticoagulant group.This overall data demonstrated that KOA patients after TKR had presented with a higher hidden blood loss, BRT, and lower swelling degrees of the knee joint after being treated by the rivaroxaban. PMID- 30290639 TI - Role of qSOFA in predicting mortality of pneumonia: A systematic review and meta analysis. AB - BACKGROUND: The concept of sepsis was redefined recently, and a new screening system termed the quick Sequential Organ Failure Assessment (qSOFA) was recommended for identifying infected patients at high risk for death. However, the predictive value of qSOFA for mortality in patients with pneumonia remains unclear. Thus, we performed a meta-analysis with the aim of determining the prognostic value of qSOFA in predicting mortality in patients with pneumonia. METHODS: Embase, Google Scholar, and PubMed (up to March 2018) were searched for related articles. We constructed a 2 * 2 contingency table according to mortality and qSOFA scores (<2 and >=2) in patients with pneumonia. Two investigators independently extracted data and assessed study eligibility. A bivariate meta analysis model was used to determine the prognostic value of qSOFA in predicting mortality. I index and Q-test were used to assess heterogeneity. RESULTS: Six studies with 17,868 patients were included. A qSOFA score >=2 was related to a higher risk for death in patients with pneumonia, with a pooled risk ratio (RR) was 3.35 (95% CI, 2.24-5.01) using a random-effects model (I = 89.4%). The pooled sensitivity and specificity of a qSOFA score >=2 to predict mortality in patients with pneumonia were 0.43 (95% CI, 0.33-0.53) and 0.86 (95% CI, 0.76-0.92), respectively. The diagnostic OR was 4 (95% CI, 3-6). The area under the summary receiver operator characteristic (SROC) curve was 0.67 (95% CI, 0.63-0.71). When we calculated the community-acquired pneumonia (CAP) subgroup, the pooled sensitivity and specificity were 0.36 (95% CI, 0.26-0.48) and 0.91 (95% CI, 0.84 0.95), respectively. The area under the SROC curve was 0.70 (95% CI, 0.66-0.74). CONCLUSIONS: A qSOFA score >=2 is strongly associated with mortality in patients with pneumonia, but the poor sensitivity of qSOFA may have limitations in the early identification of mortality in patients with pneumonia. PMID- 30290640 TI - A meta-analysis of safety and efficacy of regorafenib for refractory metastatic colorectal cancer. AB - BACKGROUND: Patients with metastatic colorectal cancer (mCRC) often suffer from progressive disease despite previous therapy. It has been a great challenge for those patients. In 2012, regorafenib was approved for mCRC. In this meta analysis, we aimed to collect and present existing data to explorethe clinical use of regorafenib. METHODS: The online electronic databases, such as PubMed, Embase, and the Cochrane library, updated to November 2017 were systematically searched. Trials on the effectiveness of regorafenib in patients who suffer from treatment-refractory metastatic colorectal cancer were included, of which the main outcomes included 3 parameters: overall survival (OS), progression-free survival (PFS), and grade 3/4 AE. RESULTS: Totally, 4 trials were included in this meta-analysis. The OD was significantly better with the use of regorafenib (OR = 0.78, 95%CI = 0.65-0.94, I = 69%, P = .008), and PFS (OR = 0.52, 95%CI = 0.34-0.79, I = 97%, P = .002). However, the most common toxicities occurred more frequently in the regorafenib group than the control group (OR = 3.73, 95%CI = 1.68-8.28, I = 79%, P = .001). CONCLUSION: Regorafenib demonstrates better efficacy and has manageable adverse-event profile for treatment-refractory mCRC. Considering the safety feature of regorafenib, further studies and clinical trials are warranted to investigate the dosing of regorafenib and alternative approaches are needed to explore predictive biomarker fortherapy selection. PMID- 30290641 TI - Relationship between the anxiety/depression and care burden of the major caregiver of stroke patients. AB - To investigate the anxiety/depression of caregivers of stroke patients.This study used a cross-sectional survey design and convenience sampling.Totally, 117 caregivers of stroke patients were enrolled. Data were collected from questionnaires. Hamilton anxiety scale, Hamilton depression scale, and Zarit caregiver burden interview were performed. Multiple linear regression and correlation analysis were used.The anxiety score, depression score and total burden score of 117 stroke caregivers were 16.56 +/- 8.02, 18.63 +/- 9.39, and 25.88 +/- 10.35, respectively. Anxiety symptoms, mild to moderate depressive symptoms, and severe depressive symptoms were found in 43.9%, 26.5%, and 27.4% of the caregivers, respectively. Daily care time and medical payment method were influencing factors for anxiety and depression (P < .05). Both anxiety and depression were positively correlated with total care burden score (P < .01).Anxiety and depression are common in the caregivers of stroke patients and are closely related to care burdens. In this regard, appropriate home care guidance, psychological counseling and social support should be provided to the caregivers to reduce their physical and mental burden. PMID- 30290642 TI - A case report of Legionella and Mycoplasma pneumonia: Co-incidence or co infection? AB - RATIONALE: Concurrent or sequential coinfections of Legionella pneumophila and Mycoplasma pneumoniae have been reported in the past though infrequently. Distinguishing a true co-infection from cross reactivity is often challenging as the diagnosis is mostly dependent on serological testing. PATIENT CONCERNS: A 77 year-old male presented with worsening dyspnea, cough with yellow sputum, diarrhea and fever of 2-days duration. Patient had history of chronic obstructive pulmonary disease (COPD) on home oxygen, bronchiectasis, rheumatoid arthritis (on methotrexate and leflunomide), treated pulmonary tuberculosis and 30-pack-year smoking. Chest X-ray showed bilateral interstitial changes with left lower lobe infiltrate. On day 5, his urine antigen for L pneumophila serogroup 1 was reported positive. The following day his serum M pneumoniae IgM antibody titers were reported elevated at 6647 U/mL. Patient was started on antibiotics and placed on non-invasive positive pressure ventilation. DIAGNOSIS: The patient was diagnosed with possible Legionella and Mycoplasma co-infection. OUTCOMES: Sputum Mycoplasma polymerase chain reaction (PCR) and serum cold agglutinins were obtained on day 6 and later reported negative. He was treated with azithromycin for 10 days with clinical improvement. LESSONS: Serological testing alone is an indirect measure with poor sensitivity and specificity and has its own limitations. Urine antigen detection confirms L pneumophila serogroup 1 infection in a patient with suggestive symptoms. However, diagnosis of M pneumonia should be based on combination of tests including serology and PCR to confirm true co infection. PMID- 30290643 TI - Induction therapy for clinical stage T2N0M0 esophageal cancer: A systematic review and meta-analysis. AB - OBJECTIVE: It is still controversial whether patients with clinical T2N0M0 (cT2N0M0) esophageal cancer are treated with induction therapy. The aim of this study was to determine the effect of induction therapy on cT2N0M0 esophageal cancer. METHODS AND MATERIALS: We searched PubMed, Embase, the Cochrane Library, and Medline databases from inception up to May 1, 2017. This meta-analysis was performed to compare odds ratios (OR) for 5-year overall survival (OS), pathologically understaged and overstaged after esophagectomy. RESULTS: Eight retrospective studies of 2646 patients were included in the meta-analysis. Data showed that no statistically significant difference in 5-year over survival was observed between induction therapy group and direct operation group. The pooled OR and 95% confidence interval (CI) for 5-year OS were 0.92 (95% CI = 0.72-1.18; P = .52). Whereas, compared with induction therapy group, direct operation group had more pathologically understaged and less overstaged after esophagectomy. CONCLUSIONS: Currentclinical staging for T2N0M0 esophageal carcinoma remains inaccurate. In this study, we found that direct operation group had more pathologically understaged and less overstaged after esophagectomy compared with induction therapy group. Induction therapy could degrade the tumor staging but not improve the patient's survival. PMID- 30290644 TI - Quantitative evaluation of retinal artery occlusion using optical coherence tomography angiography: A case report. AB - RATIONALE: Retinal artery occlusion (RAO) results in painless, catastrophic vision loss in a period of seconds. Optical coherence tomography angiography (OCTA) can image retinal microcirculation, which is helpful to evaluate treatment response during the follow-up period. Using a single case with central RAO, we report its retinal perfusion changes before and after treatment using OCTA. PATIENT CONCERNS: A 36-year-old Chinese man came to our clinic with a sudden, painless loss of vision (hand motion) in his left eye. A vasodilator (nicotinic acid) was used as the primary treatment. OCTA imaging and a visual field examination were performed to assess the retinal perfusion changes before and after treatment. DIAGNOSIS: Retinal artery occlusion was considered. INTERVENTIONS: This patient was treated with an inhaled oxygen-carbon dioxide mixture, nicotinic acid tablets (100 mg) taken orally twice a day, and intravenous infusion of nicotinic acid injections (60 mg) combined with 0.9% sodium chloride injections (100 ml) once a day for vasodilation. OUTCOMES: After treatment and 9 months of follow-up, the vessel density of the left eye at the 9 month follow-up appointment was improved in all quadrants. LESSONS: Retinal edema and retinal atrophy were observed at the RAO onset and several months later, respectively. However, macular perfusion gradually increased after treatment. The timely administration of a vasodilator and the presence of the cilioretinal artery play important roles in the prevention of profound vision loss. PMID- 30290645 TI - Th17 cells over 5.9% at admission indicate poor prognosis in patients with HBV related acute-on-chronic liver failure. AB - Our previous study demonstrated that Th17 cells increased significantly in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV ACLF). However, their prognostic role in HBV-ACLF patients remains unknown.Sixty eight consecutive HBV-ACLF patients were enrolled in this cohort study. Th17 cells were examined using flow cytometry. Disease severity scores were assessed. ROC curves were used to evaluate the value in predicting prognosis. Survival was analyzed using Kaplan-Meier curves. Predictors of mortality were determined by regression analysis.Th17 cells were significantly higher in HBV-ACLF patients compared to patients with chronic hepatitis B and normal controls (both P < .001). Also, Th17 cells were higher in nonsurviving HBV-ACLF patients than in surviving patients (P = .014). Th17 cells were positively correlated with CLIF Consortium ACLF (CLIF-C ACLF) score (r = 0.240, P = .048). ROC curves showed that the frequency of Th17 cells had accuracy in predicting 90-day prognosis equivalent to MELD, MELD-Na and CLIF-C ACLF scores in HBV-ACLF (P = .34, P = .26, and P = .15, respectively). More importantly, the area under the ROC curve (AUROC) increased when Th17 cells were combined with MELD, MELD-Na or CLIF-C ACLF score than using Th17 cells alone (P = .021, P = .006, and P = .023, respectively). Kaplan-Meier analysis revealed that higher Th17 cells (>=5.9%) were closely associated with poor overall survival in HBV-ACLF (P = .0086). Additionally, multivariate regression analysis showed that the frequency of Th17 cells over 5.9% was an independent predictor of mortality (OR = 0.154, P = .025).Circulating Th17 cells positively correlated with disease severity in HBV ACLF. The frequency of Th17 cells over 5.9% could serve as a prognostic biomarker for HBV-ACLF patients. PMID- 30290646 TI - Effect of Liuzijue Qigong on patients with chronic obstructive pulmonary disease: Protocol for a systematic review and meta-analysis. AB - BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide with a substantial and increasing social and economic burden. Liuzijue Qigong is a kind of traditional Chinese Qigong exercises that Traditional Chinese Medicine practitioners prescribe to individuals with COPD to strengthen the internal organs' function. Liuzijue Qigong was recommended for use in COPD rehabilitation, and some clinical trials indicate that Liuzijue Qigong would produce better functional capacity and quality of life of individuals with COPD. The objective of this study is to conduct a systematic review of the existing studies to assess effectiveness and safety of Liuzijue Qigong for the prevention or treatment of COPD in patients. METHODS: We will perform the comprehensive literature search in English and Chinese electronic database. The publication period will be from inception to the search date. In addition, the clinical trial registries, dissertations, informal publication, grey literature, reference lists of studies, systematic reviews, and conference abstracts will also be collected. Two reviewers will identify relevant studies, extract data information, and then assess the methodical quality by the Cochrane risk of bias assessment tool. Only randomized controlled trials comparing Liuzijue Qigong against other intervention or nonintervention will be included. Data will be synthesized by either fixed-effect or random-effect model regarding to a heterogeneity test. The routine lung function, arterial blood gas tensions, partial pressure of carbon dioxide, functional capacity, 30 seconds sit to-stand test, respiratory function, maximal inspiration pressure, maximal expiratory pressure, airway resistance, and specific airway conductance will be assessed as primary outcomes. The secondary outcomes involved dyspnea, and fatigue levels, respiratory muscle strength, upper and lower limb muscle strength, handgrip strength test, and health-related quality of life and safety. Meta-analysis will be performed by using Cochrane's Review Manager software (version 5.3.5). RESULTS: This systematic review and meta-analysis will provide a high-quality synthesis and evaluate the efficacy and safety based on current relevant literature evidence of Liuzijue Qigong intervention for COPD patient. CONCLUSION: Our systematic review will provide evidence to determine whether Liuzijue Qigong is an effective and safe approach to prevention and treatment of COPD patients. PMID- 30290647 TI - An observational study of the epidermal growth factor receptor-tyrosine kinase inhibitor resistance mechanism in epidermal growth factor receptor gene mutation positive non-small cell lung cancer. AB - Non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutation show a high response to EGFR-tyrosine kinase inhibitor (EGFR TKI). Clinically, EGFR-positive NSCLC acquires several resistance mechanisms during EGFR-TKI treatment, such as the emergence of a secondary mutation (T790M), MET gene amplification, and transformation to small cell lung cancer. However, the mechanism of resistance to afatinib, a second-generation EGFR-TKI, remains unclear. In this study, we prospectively investigate the mechanism of resistance to afatinib using proteomic analyses.In total, 35 EGFR-positive NSCLC patients of both sexes and >=20 years old will be included. NSCLC patients with major obstacles in major organs, such as bone marrow, heart, lung, liver, and kidney, will be excluded. Eligible patients will be administered afatinib or gefitinib until disease progression and proteomic analysis will be performed with biopsy samples before treatment and at disease progression.The primary outcome is to detect the potential predictive anomalies in proteins that can be candidates for the resistance factor of afatinib. The secondary outcome is to detect gene and protein abnormalities affecting progression-free survival, response rate, and rate of disease control in afatinib therapy.The protocol was approved by the institutional review boards of Kyoto Prefectural University of Medicine and all the participating hospitals. Written informed consent was obtained from all patients before registration, in accordance with the Declaration of Helsinki. The results of the study will be disseminated via publications in peer-reviewed journals.Trial registration number is UMIN000031013. PMID- 30290648 TI - Fecal microbiota transplantation for patients with irritable bowel syndrome: A meta-analysis protocol. AB - Irritable bowel syndrome (IBS) is a common functional bowel disease characterized by chronic or recurrent abdominal pain, bloating, constipation, and diarrhea. Many patients with IBS have a poor quality of life due to abdominal discomfort, diarrhea, constipation, and the presence of other diseases. At present, intestinal motility inhibitors, adsorbents, astringents, intestinal mucosal protective agents, and antidepressants have been combined to treat IBS, but the treatment process is long, which results in a large economic burden to patients. Fecal microbiota transplantation (FMT) is a treatment involving the transplantation of functional bacteria from healthy human feces into the gastrointestinal tract of patients; thus, replacing the intestinal flora and modulating intestinal and extra-intestinal diseases. In recent years, the efficacy and economic benefits of FMT in the treatment of IBS have received increasing attention from researchers.A search for randomized controlled trials (RCTs) on treating IBS with FMT will be performed using 9 databases, including PubMed, the Cochrane Library, Embase, ClinicalTrails, China National Knowledge Infrastructure, Sino Med, ScienceDirect, VIP, and Wanfang Data. Two reviewers will independently screen data extraction studies and assess study quality and risk of bias. The risk of bias for each RCT will be assessed against the Cochrane Handbook standards to assess methodological quality. RevMan V.5.3 software will be used to calculate data synthesis when meta-analysis is allowed.This study will provide a high-quality synthesis of existing evidence on the effectiveness and safety of FMT in the treatment of IBS.This study will determine if FMT is an effective and safe intervention for IBS.PROSPERO registration number is PROSPERO CRD42018108080.

AB - The purpose of this study was to identify the risk factors for adverse events during single-port video-assisted thoracoscopic (SPVATS) anatomical resections.We retrospectively reviewed patients who had undergone SPVATS anatomic resections between January 2014 and February 2017 in Coruna University Hospital's Minimally Invasive Thoracic Surgery Unit (CHUAC, Spain) and Chang Gung Memorial Hospital (CGMH, Taiwan). Four hundred forty-two patients (male: 306, female: 136) were enrolled in this study. Logistic regression analysis was performed on variables for postoperative complications.Postoperative complications with a 30-day mortality occurred in 94 patients (21.3%) and with a 90-day mortality in 3 patients (0.7%) while the major complication rate was 3.9%. Prolonged air leak (PAL > 5 days) was the most common complication and came by postoperative arrhythmia. Logistic regression indicated that pleural symphysis (odds ratio (OR), 1.91; 95% confidence interval (CI), 1.14-3.18; P = .014), computed tomography (CT) pulmonary emphysema (OR, 2.63; 95% CI, 1.41-4.76; P = .002), well developed pulmonary CT fissure line (OR, 0.49; 95% CI, 0.29-0.84; P = .009), and tumor size (>=3 cm) (OR, 2.15; 95% CI, 1.30-3.57; P = .003) were predictors of postoperative complications.Our preliminary results revealed that SPVATS anatomic resection achieves acceptable 30- and 90-day surgery related mortality (0.7%) and major complications rate (3.9%). Prolonged Air leak (PAL > 5 days) was the most common postoperative complication. Pleural symphysis, pulmonary emphysema, well developed pulmonary CT fissure line and tumor size (>=3 cm) were predictors of adverse events during SPVATS anatomic resection. PMID- 30290650 TI - New vertebral fractures after osteoporotic vertebral compression fracture between balloon kyphoplasty and nonsurgical treatment PRISMA. AB - BACKGROUND: Because of aging of population, osteoporotic vertebral compression fracture (OVCF) appears an increasing incidence rate. Conservative therapy (CT) and balloon kyphoplasty (BKP) have been used to treat OVCFs. However, an increase in new vertebral compression fractures at nontreated levels following BKP is of concern. It is still not clear whether new fractures were a result of BKP and the purpose of this meta-analysis was to evaluate the new fractures risk after BKP compared with CT. METHODS: An exhaustive literature search of PubMed, EMBASE, and the Cochrane Library was conducted to identify randomized controlled trials and prospective nonrandomized controlled study that compared BKP with CT for patients suffering OVCF. A random-effect model was used. Results were reported as standardized mean difference or risk ratio with 95% confidence interval. RESULTS: Twelve studies were included and there was no significant difference in total new fractures (P = .33) and adjacent fractures (P = .83) between 2 treatments. Subgroup analyses did not demonstrate significant differences in follow-up period, mean age, anti-osteoporosis therapy, and the proportion of women. CONCLUSION: Our systematic review revealed that an increased risk of fracture of vertebral bodies was not associated with BKP compared with CT. PMID- 30290651 TI - Inflammatory myofibroblastic lung tumor transforming into intracranial desmoplastic noninfantile ganglioglioma: A case report and literature review. AB - RATIONALE: Inflammatory myofibroblastic tumor (IMT) of the lung often arises from excessive inflammatory response. It is one of the rare benign tumors of the lung, while desmoplastic noninfant gangliogliomas (DNIG), on the contrary, are rare intracranial benign tumors often seen in children within the first one and a half years of life. PATIENT CONCERNS: We present a 12-year-old girl with 2 months history of none productive cough and right-sided chest pain. DIAGNOSES: Computer tomography scan of the chest revealed a soft tissue mass at the right upper lobe which was consistent with IMT. Histopathologic examination confirmed the diagnosis of IMT. INTERVENTIONS: Thoracic surgery was successfully carried out and she further received radiotherapy. The patient recovered initially. OUTCOMES: Two years later, she complained of seizures during follow-up. Magnetic resonance imaging of the head revealed DNIG. We achieved total resection of the major lesions and she was further treated with radiotherapy. She is currently well and in school. Histopathologic examination confirmed the diagnosis of DNIG. LESIONS: We speculate that IMT might have transformed into intracranial DNIG through metastatic process or as a result of genetic mutations or chromosomal abrasions. PMID- 30290652 TI - Early stage ovarian carcinoma with symptoms mimicking tuberculous peritonitis in a postmenopausal woman: A case report. AB - RATIONALE: Ovarian cancer has the poorest prognosis of the gynecological cancers. Early diagnosis and treatment are important, but early-stage ovarian carcinoma has nonspecific symptoms. Ultrasonography, computed tomography, magnetic resonance imaging, and serum CA-125 levels can be helpful but may not elucidate cases of diffuse peritoneal diseases mimicking carcinomatosis. PATIENT CONCERNS: The patient had intermittent abdominal discomfort and dysuria. Abdominal-pelvic computed tomography findings were suspicious for peritoneal tuberculosis (TB) and a small cystic mass in the left ovary. The CA-125 values were normal. DIAGNOSES: She underwent laparoscopy for pathologic confirmation of tuberculous peritonitis and management of the ovary mass. Bilateral adnexectomy was performed. Histopathological examination of the surgical specimen revealed a serous ovarian carcinoma in her left ovary and salpinx. INTERVENTIONS: Laparoscopic hysterectomy, pelvic lymphadenectomy, para-aortic nodal dissection, and omentectomy were carried out for staging evaluation. OUTCOMES: We encountered a rare case of ovary cancer stage IA serous ovarian carcinoma incidentally discovered by laparoscopy in a postmenopausal woman. She received adjuvant chemotherapy without relapse. LESSONS: Peritoneal TB may mimic peritoneal or ovarian carcinoma, but the reverse case is rare. Hence, gynecologists should be careful in assessment of patients before treatment. PMID- 30290653 TI - Prepregnancy obesity status and risks on pregnancy outcomes in Shanghai: A prospective cohort study. AB - Obesity in women of reproductive age is not only associated with numerous adverse maternal and fetal effects prenatally but also exerts a negative influence on female fertility. The aim of this study was to investigate the situation of prepregnant obesity in Shanghai and explore the impact of prepregnant obesity on gestational weight gain as well as other pregnancy outcomes. A prospective hospital-based pregnant women cohort was established in Shanghai since January 2015. All pregnant women who were registered and expected to deliver in this hospital were included in the cohort. Nearly one fourth of pregnant women in Shanghai were overweight/obese and the prevalence of overweight/obesity was more common among women with advancing age (P < .001). Women prepregnancy overweight/obesity was associated with 3.5-fold higher risk of excessive gestational weight gain (odds ratio, OR 3.58; 95% confidence interval, CI, 2.82 4.55; P < .001). Women prepregnancy BMI was statistically related to pregnancy outcomes as macrosomia (OR 2.24; 95% CI, 1.55-3.23; P < .001), cesarean delivery (OR 2.04; 95% CI, 1.60-2.62; P < .001), maternal complications (OR 1.53; 95% CI, 1.18-1.98; P < .001). Prepregnancy obesity is associated with a much higher risk of excessive gestational weight gain and pregnancy outcomes in Shanghai. Further interventions targeting maternal obesity, especially prepregnancy obesity are required. PMID- 30290654 TI - Bystander cardiopulmonary resuscitation training in primary and secondary school children in China and the impact of neighborhood socioeconomic status: A prospective controlled trial. AB - BACKGROUND: The World Health Organization (WHO) has endorsed school bystander cardiopulmonary resuscitation (CPR) training programs. But related researches in China are limited. Therefore, we conducted this study to assess bystander CPR training in school children in China and the impact of neighborhood socio economic status (SES) on. METHODS: A total of 1,093 students from seven schools in Zhejiang province participated in this study. Theoretical and practical bystander CPR training were conducted in instructor-led classes. Students completed a 10-statement questionnaire before and after training, and then underwent a skills assessment during a simulated basic life support (BLS) scenario. Subgroup analyses were stratified according to neighborhood SES. RESULTS: Before training, most students (72.83%) had a strong desire to learn bystander CPR and share with others. After training, bystander CPR theory was significantly improved (P < .01), and 92.64% students reached an 85-100% performance rate in a simulated BLS scenario. Students from low-SES neighborhoods had less pre-training knowledge of bystander CPR (P < .01). However, their performance was similar with students from higher-SES neighborhoods on the post training questionnaire and the skills assessment, and better among students aged 13-14 years. CONCLUSION: School children in China have a poor pre-training knowledge of bystander CPR. However, with training, there was a significant improvement in the basic theory and skills of CPR. Bystander CPR training efforts should be targeted to Chinese primary and secondary school children, especially in low-SES neighborhoods. PMID- 30290655 TI - Admissions to intensive cardiac care units in France in 2014: A cross-sectional, nationwide population-based study. AB - Geographic variation in admission to the intensive cardiac care unit (ICCU) might question about the efficiency and the equity of the healthcare system. The aim was to explain geographic variation in the rate of admission to ICCU for coronary artery disease (CAD) or heart failure (HF) in France.We conducted a retrospective study based on the French national hospital discharge database. All inpatient stays for CAD or HF with an admission to an ICCU in 2014 were included. We estimated population-based age and sex-standardized ICCU admission rates at the department level. We separately modeled the department-level admission rates for HF and CAD using generalized linear models.In all, 61,010 stays for CAD and 27,828 stays for HF had at least 1 ICCU admission. The ICCU admission rates were explained by the admission rate for CAD, by the diabetes prevalence, by the proportion of the population >75 years, and by the drive time to the ICCU.This work sheds light on the finding of substantial geographic variation in the ICCU admission rates for CAD and HF in France. This variation is explained by both the age and the health status of the population and also by the drive time to the closest ICCU for HF. Moreover, ICCU admission for HF might be more prone to unwarranted variations due to medical practice patterns. PMID- 30290656 TI - Comparing stand-alone oblique lumbar interbody fusion with posterior lumbar interbody fusion for revision of rostral adjacent segment disease: A STROBE compliant study. AB - Spinal fusion has become a standard treatment for symptomatic intervertebral degenerative disc disease. The present study aimed to compare perioperative parameters, clinical outcomes, and radiographic results of stand-alone oblique lumbar interbody fusion (OLIF) with posterior lumbar interbody fusion (PLIF) for the revision of rostral adjacent segment disease (ASD) following prior posterior lumbar fusion.Thirty-six patients who underwent revision surgeries for rostral ASD were retrospectively reviewed. Among them, 17 patients underwent stand-alone OLIF (OLIF group) and 19 patients underwent PLIF (PLIF group). The length of operation, intraoperative hemorrhage, bed rest duration, and length of hospital stay were compared between the 2 groups. Clinical results were evaluated with the Oswestry Disability Index (ODI) and visual analog scale (VAS). Radiological results were evaluated with disc height (DH), foraminal height (FH), retrolisthesis index (RI), and lumbar lordosis (LL), as well as the fusion rate and cage subsidence. Follow-up results at 1 week, 3 months, and 12 months postoperatively were compared between the 2 groups.The OLIF group had less intraoperative blood loss, shorter operative time, bed rest time, and hospital stay than did the PLIF group (P < .05). The OLIF group had lower VAS scores for back pain than the PLIF group at 1 week and 3 months postoperatively (P < .05), and lower VAS scores for leg pain than the PLIF group at 1 week postoperatively (P < .05). The OLIF group had lower ODI than the PLIF group at 1 week and 3 months postoperatively (P < .05). No significant differences were found in DH and FH between the 2 groups preoperatively (P > .05); the OLIF group showed higher DH and FH than the PLIF group at all time points (P < .05). No significant differences were found in RI and LL between the 2 groups at any time point. All patients achieved fusion at 12 months postoperatively, and cage subsidence was not observed in either group.OLIF is effective and safe for the treatment of rostral ASD following prior posterior lumbar fusion, and is superior to PLIF in terms of perioperative parameters, short-term clinical outcomes, and DH restoration, with similar fusion and reduction rates. PMID- 30290657 TI - Factors influencing class agreement and medical expenditure by age in South Korea. AB - BACKGROUND: There are not many studies evaluating the factors affecting medical expenditure for different age groups, income classes, and subjective social classes. Therefore, this study evaluates the agreement between income class, objective class, and subjective social class and analyzes the factors that affect medical expenditure by age group. METHODS: Multiple regression analysis and chi test were conducted to evaluate the compatibility between income quintiles and subjective social classes and to identify the factors influencing medical expenditure by subjective social class and age using raw data from the 2013 Korea Health Panel (n = 9,385) of the Korea Institute for Health and Social Affairs and the National Health Insurance Service. RESULTS: When the class compatibility between income quintiles and subjective social classes was analyzed by age group, young people in the first, second, and third income quintiles considered themselves to be in the second subjective social class while and those in the fourth and fifth income quintiles considered themselves to be in the third subjective social class. Moreover, middle-aged and old people in the first, second, third, and fourth income quintile considered themselves to be in the second subjective social class while those in the fifth income quintile considered themselves to be in the third subjective social class. CONCLUSION: Social support, public health approaches, and medical treatment service models are needed to eliminate comparative deprivation among individuals. PMID- 30290658 TI - Young male breast cancer, a small crowd, the survival, and prognosis?: A population-based study. AB - Women diagnosed with breast cancer at young age often have poorprognoses. Yet, few studies have focused on the prognoses of young men with breast cancer. We therefore used Surveillance, Epidemiology, and End Results (SEER) population based data and identified 151 male patients with breast cancer aged <40 years between 1988 and 2012. Propensity score matching analysis was used to balance the clinical variables among different groups. Kaplan-Meier curves were applied to compare the survival differences. The subgroup variables on cancer-specific survival (CSS) and overall survival (OS) were analyzed by the Cox proportional hazard model. Results showed that male patients with breast cancer aged <40 had a significant OS benefit compared with those aged >=40 years (P < .001). The significant difference of the CSS was not found (P > .05). Compared with the male patients with breast cancer aged >=40, those aged <40 had significant OS benefit in most subgroups (P < .05). Compared with the female patients with breast cancer aged <40, the male patients with breast cancer aged <40 had worse OS and CSS benefit only in the subgroup with progesterone receptor and estrogen receptor positive (P < .05). In conclusion, we demonstrated that young male patients with breast cancer had better OS compared with elder male patients with breast cancer. However, the survival benefit was not found compared with young female patients with breast cancer. PMID- 30290659 TI - Significance of contrast-enhanced ultrasonography in differential diagnosis of thyroid nodules. AB - The present study was aimed to compare the application values between 2 dimensional color Doppler ultrasonography (2DUS) and contrast-enhanced ultrasonography (CEUS) in the differential diagnosis of thyroid malignant nodules.A total of 124 patients suspectedly diagnosed with malignant thyroid nodules under conventional gray-scale ultrasonography were recruited in this study. All enrolled patients were examined by both 2DUS and CEUS.A total of 153 nodules (94.44%) and 45 cases (90.00%) with malignant nodules were detected by the CEUS. No significant differences were noted in nodule detection rates between 2DUS and CEUS (chi = 1.170, P = .279; chi = 0.796, P = .372). The aspect ratio, microcalcification, internal echo, borderline, Vmax, resistance index, and total scores of malignant nodules were higher than those of benign nodules (all P < .05) when diagnosed by 2DUS. The peripheral/internal enhancement time, peak intensity, local enhancement, ring enhancement, and total scores of malignant nodules were significantly higher compared with those of benign nodules (all P < .05) by CEUS. Total score of malignant nodules diagnosed by 2DUS was approximately 3.5 and 2.3 points for CEUS. The diagnostic accuracy of 2DUS as observed by area under the curve was 0.821 with the cut-off value of 3.9, the sensitivity was 82.5%, and the specificity was 85.6%. The diagnostic accuracy of CEUS was 0.862 with the cut-off value of 2.8, the sensitivity was 86.7%, and the specificity was 91.3%.Both 2DUS and CEUS are worthy of application values in the differential diagnosis from benign to malignant thyroid nodules. PMID- 30290660 TI - Comparison of diabetes risk estimate in the cities of Riyadh and Amman. AB - A significant rise in the prevalence of type 2 diabetes mellitus (T2DM) in the Middle-east and North Africa (MENA) region has seen over the last few decades. The present observational study aimed to evaluate and compare the risk of developing T2DM in the cities of Riyadh and Amman using the Arab Diabetes Risk Assessment Questionnaire (ARABRISK).The ARABRISK was administered in a total of 1116 healthy male and female individuals in the age group of 40 to 74 years with no prior history of diabetes in the city of Riyadh (Saudi Arabia) and Amman (Jordan). ARABRISK is an Arabic version of the Canadian Diabetes Risk Assessment Questionnaire (CANRISK), which was adapted and validated for the use in Arab speaking individuals in Saudi Arabia and Jordan.The participants from Amman region had higher mean total ARABRISK score compared to the Riyadh region for all categories of ARABRISK. However, the difference was significant in both low- and high-risk categories (P = .02 and P = .01, respectively) but not significant for moderate category (P = .17). In the Riyadh population, female participants had significantly higher ARABRISK total scores compared to male in both moderate- and high-risk categories (P = .01). However, in the Amman population, male participants had significantly higher ARABRISK total scores compared to female in both low- and moderate-risk categories (P = .01).The present study suggested an increased risk of developing T2DM in the cities of Riyadh and Amman. However, the population of Amman had a higher risk of developing T2DM compared to the population of Riyadh. PMID- 30290661 TI - Retrospective analysis of concurrent docetaxel and epirubicin neoadjuvant versus adjuvant chemotherapy: Which leads to better outcomes for different subtype breast cancer patients? AB - Different biological subtype breast cancers respond differently to neoadjuvant chemotherapy, but it is unknown whether neoadjuvant or adjuvant chemotherapy leads to different long-term survival in each specific subtype although equal outcomes have been reported in general population. This study sought to clarify whether the selection of either neoadjuvant or adjuvant chemotherapy was linked to a differential survival benefit based on breast cancer subtypes.A prospectively maintained breast cancer database was queried from 2000 to 2008. All patients with a diagnosis of stage II and III breast cancer who received neoadjuvant or adjuvant chemotherapy were identified, only patients receiving docetaxel and epirubicin (TA) regimen were included. Patients were divided according to the administration of neoadjuvant or adjuvant chemotherapy. The biological subtypes were determined by immunohistochemical tests. The outcomes between neoadjuvant and adjuvant chemotherapy were compared in each different subtype. Kaplan-Meier curves were generated, and the Cox model was used to estimate the association between death risk and chemotherapy timing while adjusting for potentially confounding factors. P values < .05 were considered statistically significant.Of the 406 patients included, 201 (49.5%) received neoadjuvant chemotherapy, and 205 (50.5%) received an adjuvant TA regimen. Patients with the HER2+ and TNBC subtypes showed significantly higher pCR rates than patients with luminal types (P < .05). In general population, the neoadjuvant and adjuvant chemotherapy groups showed little survival variance (HR=1.15, 95% confidence interval (CI) .69-1.91, P=.60). In luminal B-like patients, neoadjuvant chemotherapy led to worse overall survival (OS) than adjuvant therapy (HR=2.92, 95%CI 1.20 to 8.31, P = .02). In patients with the HER2+ subtype, neoadjuvant treatment corresponded to better OS (HR = .10, 95%CI .02-.58, P = .01). In contrast, patients with luminal A-like (HR = 1.14, 95%CI .53-2.43, P = .74) and TNBC disease (HR = 1.00, 95%CI .27-3.73, P = >.99) who underwent neoadjuvant chemotherapy showed equivalent OS when compared to patients undergoing adjuvant therapy.Neoadjuvant versus adjuvant chemotherapy results in a disparate impact on overall survival among patients with variant subtype breast cancer. When neoadjuvant chemotherapy was given, luminal B-like patients showed worse outcome, while patients with HER2+ disease had better OS. Prospective studies are necessary to determine and optimize the timing of chemotherapy for breast cancers with different molecular backgrounds. PMID- 30290662 TI - Indocyanine green angiography for preserving the ureteral branch of the uterine artery during radical hysterectomy: Two case report. AB - RATIONALE: Conventional radical hysterectomy is frequently associated with postoperative ureteral ischemic necrosis, urinary fistula, stenosis, and kidney seeper. Some have suggested that preserving the ureteral branch during radical hysterectomy may reduce the incidence of ureteral complications. However, the feasibility of such preservation has not been explored using intraoperative imaging techniques. PATIENT CONCERNS: Two cervical cancer patients aged 45 and 53 years were selected to undergo surgery in our hospital in October 2017. Both patients showed normal function of major organs and no special treatment was deemed necessary based on their subjective symptoms and preoperative examination. DIAGNOSES: Both patients were diagnosed with cervical cancer in stage Ib1 according to the staging scheme of the International Federation of Gynecology and Obstetrics (FIGO 2009). INTERVENTIONS: Two patients underwent ureteral branch sparing radical hysterectomy. During surgery, indocyanine green (ICG) fluorescence angiography was used to identify the ureteral branch and evaluate perfusion of the uterine artery, its ureteral branch and the ureter. OUTCOMES: The uterine artery and ureteral branch were clearly labeled by green fluorescence, as were the distal serous layer of the ureter and tissue supplied by the ureteral branch. During 4-month follow-up, neither patient suffered hydronephrosis, ureteral fistula or stricture. LESSONS: ICG angiography is a useful intraoperative imaging technique for identifying the ureteral branch and evaluating the branch-sparing surgery. Based on real-time angiography, sparing the ureteral branch can maintain blood supply to the ureter distal serous layer and neighboring tissues. PMID- 30290663 TI - The efficacy of accommodative versus monofocal intraocular lenses for cataract patients: A systematic review and meta-analysis. AB - INTRODUCTION: We performed a systematic review and meta-analysis to evaluate whether accommodative intraocular lenses (AC-IOLs) are superior for cataract patients compared with monofocal IOLs (MF-IOLs). METHODS: Pubmed, Embase, Cochrane library, CNKI, and Wanfang databases were searched through in August 2018 for AC-IOLs versus MF-IOLs in cataract patients. Studies were pooled under either fixed-effects model or random-effects model to calculate the relative risk (RR), weighted mean difference (WMD), or standard mean difference (SMD) and their corresponding 95% confidence interval (CI). Distance-corrected near visual acuity (DCNVA) was chosen as the primary outcome. The secondary outcomes were corrected distant visual acuity (CDVA), pilocarpine-induced IOL shift, contrast sensitivity, and spectacle independence. RESULTS: Seventeen studies, involving a total of 1764 eyes, were included. Our results revealed that AC-IOLs improved DCNVA (SMD = -1.84, 95% CI = -2.56 to -1.11) and were associated with significantly greater anterior lens shift than MF-IOLs (WMD = -0.30, 95% CI = 0.37 to -0.23). Furthermore, spectacle independence was significantly better with AC-IOLs than with MF-IOLs (RR = 3.07, 95% CI = 1.06-8.89). However, there was no significant difference in CDVA and contrast sensitivity between the 2 groups. CONCLUSION: Our study confirmed that AC-IOLs can provide cataract patients with DCNVA and result in more high levels of spectacle independence than MF-IOLs. Further studies with larger data set and well-designed models are required to validate our findings. PMID- 30290664 TI - The risk factors for bone metastases in patients with colorectal cancer. AB - This retrospective analysis aim to evaluate the potential risk factors for bone metastases (BM) in patients who were diagnosed with colorectal cancer (CRC).A total of 2790 patients diagnosed with CRC between January 2006 and December 2016 were collected in this study. All patients were divided into 2 groups, BM and no BM. The associations between biomarkers (including age, gender, histopathological types, alkaline phosphatase (ALP), carcinoembryonic antigen (CEA), cancer antigen 125, and so on), and BM in patients with CRC were analyzed. All the analyses were conducted by SPSS software (version 22.0, SPSS, Chicago, IL).Of all patients, 74 (2.7%) were identified with BM. The level of serum ALP, CEA, and cancer antigen 125 in patients with BM were obviously higher than those without BM (P < .001, P = .005, and P < .001). And the cut-off values of ALP, CEA, and cancer antigen 125 were 85.5 U/L, 6.9 mmol/L, and 16.8 mmol/L, respectively.ALP, CEA, and cancer antigen 125 were identified as the independent risk factors for BM in patients with CRC. PMID- 30290665 TI - Targeted high-throughput sequencing technique for the molecular diagnosis of primary immunodeficiency disorders. AB - The aim of this study was to investigate the usefulness of targeted high throughput sequencing (HTS) for the molecular diagnosis of primary immunodeficiency diseases (PID).A total of 56 clinically diagnosed or suspected PID patients were divided into 4 groups according to the International Union of Immunological Societies Expert Committee for Primary Immunodeficiency 2015 and their chief clinical presentations. Patients and their biological family members were examined by targeted HTS, which sequenced the exons and +/-10 bp flanking introns of 171 PID-related genes panel. All significant variants were confirmed by PCR-Sanger sequencing. Pathogenicity of the variants was evaluated by using bioinformatics.A total of 117 variants in 73 genes were found in 56 patients. Accurate molecular diagnosis of PID was made in 13 (23.2%) patients, and 12 novel mutations were detected in these patients. Twenty-seven patients carried heterozygous variants that are probably pathogenic in >=2 genes; 16 patients had only 1 missense variant, or had several variants but not >1 variant was deleterious as evaluated by bioinformatics. The meaning of the targeted HTS results of these patients remains to be studied.Targeted HTS can make a precise molecular diagnosis of PID and detect more novel pathogenic mutations. More and more variations with ambiguous significance are discovered and explanation of these variations is a challenge to the clinicians. PMID- 30290666 TI - A novel fibrinogen variant in a Chinese pedigree with congenital dysfibrinogenemia caused by FGA P. Arg38Thr mutation: A case report. AB - RATIONALE: Congenital dysfibrinogenemia (CD) is characterized by altered functional properties of the fibrinogen; people who suffer from CD often have a low activity of fibrinogen and the mutation in the genomic DNA. PATIENT CONCERNS: A 6-year-old child was examined with a low activity of fibrinogen measured by Von Clauss method and PT-derived method which indicated a normal level of fibrinogen; this abnormality was also detected in her mother. The genomic DNA of all the family members was extracted, and all exons of 3 fibrinogen genes which encode fibrinogen alpha chain (FGA), fibrinogen beta chain (FGB), and fibrinogen gamma chain (FGG) were amplified by polymerase chain reaction (PCR), in addition, sanger sequencing, homologous sequence alignment and bioinformatics software were performed for the further analysis. DIAGNOSES: CD in this pedigree is associated with c.113G>C in the exon 2 of FGA which caused Arg38Thr mutation. OUTCOMES: The child and her mother showed a low plasma concentration of fibrinogen measured by Von Clauss method, whereas a normal result measured by PT-derived method; finally, c.113G>C in the exon 2 of FGA was detected in the pedigree which caused Arg38Thr mutation and it is the first report on a pedigree with CD caused by AalphaArg38Thr. LESSONS: This case gives us the lesson that not all patients with CD showed typical symptoms and laboratory test results; the result of fibrinogen concentration and antigen which is tested by Von Clauss method and immunoturbidimetric assay is various according to the condition of each CD patient. PMID- 30290667 TI - Patient quality of recovery on the day of surgery after propofol total intravenous anesthesia for vitrectomy: A randomized controlled trial. AB - BACKGROUND: Vitrectomy under general anesthesia is considered as a candidate for ambulatory surgery. An anesthetic method with high quality of postoperative recovery should be selected for successful ambulatory surgery. We thus compared quality of postoperative recovery on the day of vitrectomy using the Quality of Recovery (QoR)-40 questionnaire between propofol total intravenous anesthesia (propofol group) and desflurane inhalation anesthesia (desflurane group) as the 2 representative anesthetic methods. METHODS: Eighty-four patients (20-80 years old) undergoing elective vitrectomy under general anesthesia were randomized into 2 groups. The propofol group received propofol and remifentanil using effect-site target-controlled infusion (TCI), and the desflurane group received desflurane inhalation and remifentanil using effect-site TCI. We assessed quality of recovery at 6 hours after surgery through interviews using the QoR-40 questionnaire. We also collected data related to recovery and complications during emergence and recovery period. RESULTS: The median of QoR-40 score on the day of surgery was significantly higher in the propofol group than that in the desflurane group (181.0 vs 169.5, respectively; P = .033). In particular, propofol group had significantly higher scores for physical comfort and physical independence dimensions. The amount of remifentanil administered was significantly higher, and the emergence time was significantly longer in propofol group. However, there were no significant differences in other complications between the 2 groups. CONCLUSIONS: Propofol total intravenous anesthesia provided significantly better quality of recovery on the day of surgery than desflurane inhalation anesthesia. PMID- 30290668 TI - Primary total knee arthroplasty for complex supracondylar femoral fractures in patients with knee arthritis: A retrospective study of a patient cohort. AB - When elder arthritis patients suffered from complex supracondylar femoral fractures, their joints condition and general health condition elevate the difficulties in operation and post-surgical recovery.Here, we aimed to simplify the operation procedure by using one-step Total Knee Arthroplasty (TKA) with a stemmed femoral implant. We also investigated if this method could improve the patients' experience after the operation. The surgery including femoral osteotomy and implantation was performed on all fourteen patients by the same orthopedic specialist. The patients' hospitalization time was recorded. The recovery of knee function and patient satisfaction was evaluated by a systematic follow-up with average time 38 months, up to 5 5 years, using Hospital for Special Surgery (HSS) knee scores, the range of motion (ROM), anteroposterior and lateral radiography, and Visual Analog Scale (VAS) scores. The average of hospitalization days was 16 days. No angular deformity, malunion, or shortening were found at radiography.The average ROM was 105.2 degrees at the end of the follow-up period. The knees in all the patients show adequate stability. All patients had returned to their former daily activities. Seventeen out of 24 patients were satisfied with the outcome of the surgery.The usage of TKA with a stemmed femoral implant is a reasonable method for elderly patients suffering from supracondylar femoral fractures and concomitant knee arthritis. PMID- 30290669 TI - Association of human leukocyte antigen alleles and supertypes with immunogenicity of oral rotavirus vaccine given to infants in China. AB - Rotavirus (RV) vaccines show distinct immunogenicity in dozens of clinical trials, which is associated with multiple host and environmental factors. Previous research has demonstrated that the highly polymorphic human leukocyte antigen (HLA) system plays an essential role in regulating immune response to a variety of vaccines. This study aims to investigate the relationship between HLA polymorphisms and immunogenicity of RV vaccine.A nested case-control study was carried out among infants enrolled in phase III clinical trial of trivalent human lamb reassortant vaccine (RV3) in Henan province, China. Serum RV specific immunoglobulin A (RV-IgA) was detected before and after a 3-dose vaccination series, followed by calculation of seroconversion rates. Seroconversion was defined as a 4-fold or greater increase in RV-IgA titers between pre-vaccination and 1-month post-dose 3 vaccination. The infants who seroconverted were defined as responders, and the others without seroconversion were considered as non responders. Their HLA genotypes were obtained by using the sequence-based typing method. The HLA allele and supertype frequencies of 2 groups were analyzed statistically.Eighty-three of 133 infants seroconverted after vaccination. Twenty one HLA-A, 45 HLA-B, 24 HLA-Cw, 29 HLA-DRB1 and 16 HLA-DQB1 distinct alleles were detected. The frequency of HLA-B4001 (corrected P = .01, adjusted OR = 0.152, 95% CI = 0.048-0.475) in non-responder group was significantly higher than that in responder group. Furthermore, significant association was found between HLA-B44 supertype (corrected P = .02, adjusted OR = 0.414, 95% CI = 0.225-0.763) and RV non-response.Certain HLA allele (HLA-B4001) and supertype (HLA-B44) are potentially associated with non-response after immunization with the novel RV3 vaccine in Chinese infants. PMID- 30290670 TI - No associations exists between red blood cell distribution width and serum uric acid in both sexes. AB - The aim of this study was to determine whether there was a significant association between red blood cell distribution width (RDW) and uric acid (UA) in a large Chinese population.This was a cross-sectional study with an enrollment of 80,298 ostensibly healthy participants (48,971 males, 31,327 females) during the period from 2011 to 2015. In the study, database was grouped by sex and the association between RDW and UA was analyzed by quartiles of RDW.UA values between different sexes and RDW subgroups were analyzed by 2-way analysis of variance and Bonferroni t tests. Prevalence of hyperuricemia in different sexes was calculated. The relationship between risks of hyperuricemia and RDW level was analyzed by binary logistic regression with or without adjustment for age and body mass index.UA values were not all the same between different sexes and RDW subgroups. Males had significantly higher hyperuricemia prevalence than females (20.00% vs 6.48%, P < .01). In addition, hyperuricemia prevalence in males decreased slightly across RDW quartiles, but was stable in females. No significant association between hyperuricemia risk and RDW was found in both sexes according to the results of multivariate logistic regression analysis. Similarly, negative results were also observed in multivariate linear analysis when both RDW and UA were considered as continuous variable.We could not find any significant relationship between RDW and UA in both sexes. PMID- 30290672 TI - A large retroperitoneal lipoblastoma: A case report and literature review. AB - INTRODUCTION: Lipoblastoma is a rare benign soft tissue tumor that occurs most commonly in infants and children. However, retroperitoneal lipoblastomas are rare, occurring in <5% of cases. We report a case of large retroperitoneal lipoblastoma and the largest collection of known retroperitoneal lipoblastomas in children in the literature. CASE PRESENTATION: A 3-year-old girl presented with left abdominal mass. Magnetic resonance imaging (MRI) revealed a soft tissue mass measuring 12 * 8 * 6 cm in the retroperitoneal region. The mass had a clearly defined margin and a reticular pattern with an interposing fat component. Based on these findings, the mass was suspected to be a soft-tissue tumor, most likely lipoblastoma.Laparotomy with resection of the retroperitoneal mass was performed. The tumor was easily dissected from the retroperitoneal space without injury to surrounding structure.A histopathological examination demonstrated the mature proliferation of adipocytes and spindle-shaped cells separated by fibrovascular septa accompanied by myxoid changes. The cells were separated into lobules by septa, and areas of immature adipocytes showing a signet-ring or multivacuolar appearance were present at the periphery. Histopathological diagnosis was lipoblastoma. Follow-up at 6 months revealed no evidence of recurrence. CONCLUSION: Retroperitoneal lipoblastoma is rare and tends to be large in size when diagnosed at presentation. Complete resection should not be delayed, as impingement on the surrounding structures is imminent. PMID- 30290671 TI - Curative resolution of chronic thromboembolic pulmonary hypertension with pulmonary thromboendarterectomy in primary antiphospholipid syndrome: A case report. AB - RATIONALE: Chronic thromboembolic pulmonary hypertension (CTEPH) is a severe complication of antiphospholipid syndrome (APS). Once diagnosed, the recommendation for the treatment of CTEPH is long-term anticoagulation and pulmonary thromboendarterectomy (PTE). However, cardiac surgeons apply PTE cautiously for these patients, as there is an increased risk of perioperative complications. Here, we present the curative case of a patient with severe APS associated CTEPH treated with PTE. PATIENT CONCERNS: A 29-year-old man presented with chest pain, decreased exercise capacity, dyspnoea, and haemoptysis. DIAGNOSES: He was triple positive for antiphospholipid antibodies. Computed tomography pulmonary angiography revealed multiple, recurrent pulmonary embolisms and complete obstruction of the left pulmonary artery. He was diagnosed with APS and CTEPH. INTERVENTIONS: After balancing the risk of thrombosis and haemorrhage, the patient underwent PTE. OUTCOMES: The patient experienced symptom relief after PTE, and electrocardiography at a six-month follow-up showed a recovery of cardiac structure and pulmonary arterial pressure. LESSONS: After evaluating the thrombosis risk at an experienced treatment centre and the application of standard anticoagulation treatment, PTE may be a curative resolution for APS associated CTEPH. PMID- 30290673 TI - Short bowel syndrome caused by laparoscopic loop enterostomy of the jejunum in an adult with undiagnosed intestinal malrotation: A case report. AB - RATIONALE: Failure to recognize intestinal malrotation in adults can cause complications during surgeries, especially those with a limited operative field. We report a case of short bowel syndrome caused by mistaken creation of a loop enterostomy in the jejunum due to undiagnosed intestinal malrotation. PATIENT CONCERNS: A 72-year-old man underwent a laparoscopic right hemicolectomy and ileocolostomy because of complicated diverticulitis. Six days after the surgery, he received laparoscopic exploration because of anastomotic leak, and a laparoscopic loop ileostomy was also performed as a protective diversion stoma. One month after surgery, he complained of severe diarrhea from the enterostomy after food and water intake. An upper gastrointestinal and small bowel series revealed that the duodenojejunal junction (DJJ) did not cross the midline and there was a short distance between the DJJ and the enterostomy in the right lower quadrant. DIAGNOSES: Short bowel syndrome caused by mistaken creation of a loop enterostomy in the jejunum due to undiagnosed intestinal malrotation. INTERVENTIONS: Total parental nutrition was used and the loop enterostomy was closed 3 months after the initial surgery. OUTCOMES: The patient was discharged uneventfully 2 weeks after the loop enterostomy. LESSONS: Intestinal malrotation in adults is often encountered during routine radiological examinations. However, it may cause complications during surgery if ignored. Radiologists should keep in mind that complications may occur if a complete presurgical evaluation of intestinal malrotation is not performed, and surgeons should take caution when performing surgeries, especially those with a limited operative field. PMID- 30290674 TI - Pleural effusion resulting from bronchial tuberculosis: A case report. AB - RATIONALE: The clinical manifestations in patients with bronchial tuberculosis (BTB) are nonspecific and may pose a great diagnostic challenge. PATIENT CONCERNS: Here we describe the case of a 57-year-old man presented with right chest pain, chest tightness, and discomfort for 2 days. DIAGNOSIS: Bronchoscopic biopsy was performed which revealed subepithelial and epithelioid cell granuloma of Langerhans cell structure. The definitive diagnosis was BTB with pleural effusion. INTERVENTIONS: Treatment with a quadruple combinational antituberculous therapy was initiated. OUTCOMES: Two months later, the patient's chest distress and discomfort significantly decreased. Repeat chest radiograph revealed that the pleural fluid had been absorbed. The patient recovered after 15 months of antituberculosis treatment. LESSONS: The patient exemplifies the difficulty of diagnosing BTB, particularly the low reliability of imaging modalities. The diagnosis of BTB currently relies on bronchoscopy as well as bacteriological or pathological evidence. This report will help to lower the incidences of misdiagnosis of this disease. PMID- 30290675 TI - Evidence supporting FDA approval and CMS national coverage determinations for novel medical products, 2005 through 2016: A cross-sectional study. AB - Food and Drug Administration (FDA) and Centers for Medicare and Medicaid Services (CMS) rely on evidence from clinical trials when approving a therapeutic for marketing and insurance coverage in the US, respectively. No study has compared the quality and quantity of evidence examined by these agencies.To characterize evidence used by FDA and CMS to support marketing approval and National Coverage Determinations (NCDs), respectively, of novel therapeutics reviewed for CMS coverage from 2005 through 2016.A cross-sectional study of clinical trials described in FDA approval documents and CMS NCD memoranda. We compared the number of clinical trials used by each agency as well as the following characteristics among original clinical trials: study size, randomization, double-blinding, and control arm.Twelve medical products met our inclusion criteria. FDA approvals of these products were based on 22 pivotal trials. CMS NCDs were based on 27 original clinical trials; 14 clinical trials were used by both agencies. Between FDA pivotal and CMS original clinical trials, there was no significant difference in study size (P = .53), use of randomization (P = .75), double-blinding (P = .55), or control arm (P = .54). There was no statistically significant difference in median age between participants in trials reviewed by CMS versus those reviewed by FDA (62 vs 59 years, P = .26). The median time from FDA approval to publication of CMS NCD memorandum was 17 (interquartile range, 13-36) months.FDA approvals and CMS NCDs are based on a similar number and quality of trials, although trial participants are not reflective of the Medicare population, and the process of finalizing coverage determinations requires an additional 17 months. PMID- 30290676 TI - Case report of mixed-type autoimmune hemolytic anemia in a patient with relapsing polychondritis. AB - RATIONALE: Relapsing polychondritis (RP) is a rare autoimmune-related disease and may be associated with other autoimmune diseases. PATIENT CONCERNS: Here we reported a case of RP patients with mixed-type AIHA. The patient was diagnosed with RP in March 2008 which was treated and the patient was in stable condition. Laboratory data revealed progressive decrease in hemoglobin during her hospitalization due to pulmonary infection in 2016. Positive Coombs' test and moderate titer of anti-cold agglutinin was detected. DIAGNOSIS: Mixed-type AIHA was diagnosed as a comorbidity in this case given the circumstance that her RP was stable and low-dose oral corticosteroids was enough to maintain remission. INTERVENTIONS: The patient was treated with intravenous immunoglobulin and steroids. OUTCOMES: The patient's body temperature dropped and hemoglobin levels rose in 2 weeks. LESSONS: Reports of RP patients with autoimmune hemolytic anemia (AIHA) are extremely rare and cases with the mixed-type AIHA has not been reported. Here we describe a case of RP with mixed-type AIHA which was considered as a comorbidity rather than a complication. PMID- 30290677 TI - Investigation of rare earth elements in urine and drinking water of children in mining area. AB - To compare the contents of rare earth elements in urine and drinking water of children in the mining and control areas and evaluate the health risk of children in the mining area.Urine and drinking water of 128 children in the mining area and 125 children in the control area were collected from June to July 2015. The contents of rare earth elements were determined using inductively coupled plasma mass spectrometry.The detection rates of rare earth elements, including yttrium (Y), lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), and samarium (Sm), in the urine of children in the exposed group were all 100%, except for samarium (98%); the rates in the control group were 85.7%, 100%, 100%, 98%, 98%, and 59.2%, respectively, and the remaining elements were not detectable. The concentrations of Y, La, Ce, Pr, Nd, and Sm in the urine of children in the exposed group were significantly higher than that in the control group (P < .01). In addition, the composition ratio of lanthanum was higher than that in the control group. The detection rates of lanthanum and Ce in the drinking water of children in the exposed group were 1.44% and 0.72%, respectively. The others were not detectable; the rates in the control group were all 0%.The pollution caused by the presence of Y, La, Ce, Pr, Nd, and Sm in the mining area might affect the health of children in the area, but drinking water might not be the cause. PMID- 30290678 TI - Analysis of the risk factor for the poor prognosis of localized neuroblastoma after the surgical. AB - Neuroblastoma is a unique malignancy in infants often presenting with either localized or metastatic disease. The study was carried out to explore the risk stratification of the poor prognosis for patients underwent surgical treatment.60 patients diagnosed with neuroblastoma were primarily enrolled in the study from April 2008 to April 2016. All the patients underwent surgical treatment and received 5-year follow-up. Clinical variables, including age, International Neuroblastoma Staging System (INSS) stage, tumor size and site, histology, and MYCN status were retrospectively analyzed, and EFS was chosen as the endpoint.The median age of patients was 8.2 months and average follow-up period was 40.2 +/- 8.6 months. Among 60 patients, complete remission was achieved in 35 patients and partial remission in 14 subjects. Poor prognosis including patient death and tumor progression were overserved in 11 patients. Cox multifactor regression analysis revealed that age, histology and MYCN status had significant prognostic effect on event-free survival (EFS) rate for neuroblastoma patients underwent surgical treatment.In our study, we identified a series of prognostic factors including age, histology, and MYCN status predicting the prognosis of neuroblastoma patients after surgical treatment. PMID- 30290679 TI - Infliximab as an alternative therapy for refractory adult onset Kawasaki disease: A case report. AB - RATIONALE: Kawasaki disease (KD) is an acute febrile illness predominantly affecting children less than 5 years of age and characterized by systemic inflammation in all medium-sized arteries. Adult-onset KD (AKD) is rare with only 105 case reports published. Recently, the efficacy of infliximab (IFX) for patients with refractory KD has been demonstrated. PATIENT CONCERNS: A previously healthy 24-year-old man was admitted because of a persistent fever, and elevated serum level of AST, ALT, LDH, and CRP. DIAGNOSIS: The patients met the diagnostic criteria for KD based on the findings of persistent fever, polymorphous exanthema, unilateral cervical lymphadenopathy, non-purulent palpebral conjunctivitis and membranous desquamation. Echocardiogram revealed the dilatation at the proximal sites of the right coronary artery (7.9 mm) and left anterior descending artery (5 mm). The patient was treated with high-dose intravenous immunoglobulin (1 g/kg/day for 2 days) and ASA (100 mg daily). However, his fever and arthralgia persisted. INTERVENTIONS: He was administered single 5 mg/kg doses of IFX. OUTCOMES: He became afebrile the next day and his arthralgia improved. LESSONS: We report the first case of administration of IFX in a patient with AKD refractory to intravenous immunoglobulin (IVIG), and successful reduction of systemic inflammation. However, the effectiveness of IFX in the regression of coronary artery aneurysm remains to be determined. PMID- 30290681 TI - Isolated extradural Rosai-Dorfman disease causing the spinal cord compression: A case report. AB - RATIONALE: Rosai-Dorfman disease (RDD) is a rare benign histiocytic disease that is commonly characterized by massive painless cervical lymphadenopathy and systemic manifestations. Isolated extranodal involvement, especially spinal involvement, is extremely rare. PATIENT CONCERNS: A 28-year-old man presented with intermittent dorsodynia and bilateral lower-limb weakness and numbness. A magnetic resonance scan (MRI) showed an extradural lesion of the T6-T9 thoracic spine that lead to cord compression. DIAGNOSES: Histopathological findings showed distinctive emperipolesis and immunohistochemistry results that were positive for cluster of differentiation CD68 and S100. Therefore, we diagnosed the Rosai Dorfman disease. INTERVENTIONS: we performed a nearly total surgical resection and a limited T6-T9 laminectomy. OUTCOMES: Postoperatively, the patient's symptoms were partially relieved and experienced no recurrence during the 6-month follow-up. The preoperative diagnosis of isolated spinal RDD still remains challenging. LESSONS: Thus, we should consider RDD in the differential diagnosis of the central nervous system. Besides surgical resection, the treatment also included radiation, chemotherapy or monoclonal antibodies. However, the optimal treatment remains controversial. Therefore, we should exert all our energies on the exploration of etiology and adjuvant therapy for this disease. PMID- 30290680 TI - Rationale and design of a randomized trial of early intensive blood pressure lowering on cerebral perfusion parameters in thrombolysed acute ischemic stroke patients. AB - BACKGROUND AND RATIONALE: Uncertainty persists over the optimal management of blood pressure (BP) in the early phase of acute ischemic stroke (AIS). This study aims to determine the safety and effects of intensive BP lowering on cerebral blood flow (CBF) and functional in AIS patients treated with intravenous thrombolysis. METHODS: In a randomized controlled trial, 54 thrombolysed AIS patients with a systolic BP of 160 to 180 mm Hg will be randomized to early intensive BP lowering (systolic target range 140-160 mm Hg) or guideline-based BP management (systolic range 160-180 mm Hg) during first 72-hours using primarily intravenous labetalol. We hypothesize that early intensive BP lowering will not reduce CBF by 20% and/or increase the volume of hypoperfused tissue by >20% on computed tomographic perfusion. Clinical outcome will be assessed using a dichotomized modified Rankin scale (scores 0-1 as excellent outcome vs scores 2-6 as dead or dependent) at 90 days. Other outcome would be symptomatic intracerebral hemorrhage. The trial is registered at ClinicalTrials.gov, NCT03443596. CONCLUSION: This randomized study will provide important information about the physiological effects of BP reduction on cerebral perfusion after intravenous thrombolysis in AIS. PMID- 30290682 TI - Progression of aggressive vertebral hemangiomas during pregnancy: Three case reports and literature review. AB - RATIONALE: Vertebral hemangiomas (VHs), one of the most common benign tumors of the spine, can be aggressive, which is a rare condition and causes neurological deficits. Pregnancy is related to the worsening of aggressive VHs. The diagnosis and treatment of aggressive VHs remain challenging, especially for pregnant cases. PATIENT CONCERNS: We report 3 cases of aggressive VH in women who developed progressive neurological deficits during pregnancy among 95 patients treated for aggressive VH in our hospital in the past 15 years. DIAGNOSES AND INTERVENTIONS: All 3 patients experienced progressive deterioration of neurological function and pain at 13, 28, and 41 weeks' gestation. On radiological examination, VHs were the suspected radiological diagnoses in 2 patients; 1 patient was preoperatively misdiagnosed with a spinal metastatic tumor. All 3 patients underwent decompression surgery with intraoperative vertebroplasty and/or postoperative radiotherapy. The pathological diagnosis after surgery was all hemangiomas. OUTCOMES: In all 3 patients, there were no tumor recurrences, and neurological functions remained normal at the last follow up of 75, 38, and 15 months after the treatment, respectively. LESSONS: Pregnancy might lead to the onset of aggressive VHs. The diagnosis and treatment of VHs during pregnancy remain controversial due to concern for both maternal and fetal safety. Timely surgery could preserve neurological function. Decompression surgery by laminectomy followed by adjuvant therapies require less skill and have a shorter surgery time, and can be considered more appropriate for aggressive VHs with pregnancy. PMID- 30290683 TI - Ultrasonographic features of testicular metastasis from renal clear cell carcinoma that mimics a seminoma: A case report. AB - RATIONALE: Testicular metastases from renal cell carcinoma (RCC) are extremely rare. To the best of our knowledge, only 35 cases have been described in the literatures. PATIENT CONCERNS: A 64-year-old male presented to our urology clinic for a palpable painless mass on his right side of the scrotum by self-examination 1 week ago, with a general abdominal ultrasonographic report showing a mass in his right kidney. DIAGNOSES AND INTERVENTIONS: Scrotal B-mode ultrasound revealed a 15 * 13 * 15 mm well-defined round homogenously hypoechoic nodule with a halo at the upper pole of the right testis. Color Doppler and spectral Doppler ultrasound detected abundant intranodular and perinodular blood flow signals including both arteries and veins. Malignancy was suspected. Abdominal contrast enhanced computed tomography identified an irregular tumor in the posterior side of the right kidney, highly suspicious for renal carcinoma. The patient received right radical nephrectomy and right partial orchiectomy. Histologically, the right renal mass was diagnosed as RCC, clear cell type, grade 2. As to the right testicular mass, a metastasis from renal clear cell carcinoma was confirmed. OUTCOMES: The patient has lived with no recurrence for at least 17 months without adjuvant therapy. LESSONS: In the case, we focus on the ultrasonographic features of the testicular metastasis from RCC. Ultrasound could provide initial and helpful information for diagnosis. When finding a mass in the testicle on the ultrasound, although most of them are primary, it is important to know whether the patient has tumor history from other parts of the body. A halo may be a special feature for metastases. Contrast-enhanced ultrasound (CEUS) and ultrasonic elastography could provide more information for differential diagnoses. PMID- 30290684 TI - Regaining body weight after weight reduction further increases pulse wave velocity in obese men with metabolic syndrome. AB - Subjects with metabolic syndrome (MetS) or obesity have worse arterial stiffness. However, there have been no studies addressing time-sequential changes in pulse wave velocity (PWV) after weight loss and then regaining weight in obese non diabetic men with MetS.We prospectively enrolled 40 obese, non-diabetic men with MetS undergoing a 3-month weight reduction program. Another 26 lean and healthy men were recruited for comparisons. Oral glucose tolerance test and brachial ankle (ba) PWV were assessed in study subjects. Eighteen obese non-diabetic MetS and 15 lean control subjects had follow-ups at the 60th month.The body weight of obese MetS decreased from 94.8 +/- 7.6 to 86.1 +/- 9.0 (N = 18, P < .001) after a 3-month weight reduction program but regained gradually thereafter to 93.6 +/- 11.6 kg at the 60th month (P < .001 versus 3rd month). baPWV decreased after weight loss slightly (P = .240) while weight regain significantly increased the baPWV (from 3rd month, 1358 +/- 168 to 60th month 1539 +/- 264 cm/sec, P < .001). Systolic and diastolic blood pressure increments correlated with the increment of baPWV after weight regain. At the 60th month, lean controls (N = 15) had increases in body weight while their baPWV increased non-significantly. The increments of baPWV after weight regain in obese MetS were significantly higher than the increment of baPWV in lean controls after weight gain.In conclusion, regaining body weight after weight reduction worsened arterial stiffness with significant increase of baPWV in obese non-diabetic MetS. PMID- 30290685 TI - Vitamin D supplementation to prevent vitamin D deficiency for children with epilepsy: Randomized pragmatic trial protocol. AB - BACKGROUND: Vitamin D deficiency is highly prevalent among children with epilepsy. Lack of high-quality evidence led to variability among scientific societies recommendations. Therefore, we aim to determine the efficacy of different common doses used in the pediatric practice to maintain optimal 25 hydroxy vitamin D (25 [OH] vitamin D) level in children with epilepsy and normal baseline 25 (OH) vitamin D level over 6 months of supplementation. METHODS: This is a protocol for phase IV pragmatic randomized superiority controlled open-label trial at King Saud University Medical City in Riyadh. Children with epilepsy and receiving chronic antiepliptic medication and normal baseline 25 (OH) vitamin D level will be randomly assigned to receive Cholecalciferol 400 IU/day versus 1000 IU/day for 6 months. Our primary outcome is the proportion of children with vitamin D insufficiency (25 (OH) vitamin D level < 75nmol/L) at 6 months. Secondary outcomes include seizure treatment failure, seizure frequency, parathyroid hormone (PTH) levels, bone mineral density, and safety. DISCUSSION: Our trial is set out to evaluate the efficacy of common different vitamin D maintenance doses on 25 (OH) vitamin D level, seizure control, and bone health for children with epilepsy. The results of our study will possibly help in shaping current vitamin D guidelines for vitamin D supplementation in children with epilepsy and provide a link between 25 (OH) vitamin D level and seizure control. PMID- 30290686 TI - Predictors of early weaning failure from mechanical ventilation in critically ill patients after emergency gastrointestinal surgery: A retrospective study. AB - Mechanical ventilation (MV) is the most common therapeutic modality used for critically ill patients. However, prolonged MV is associated with high morbidity and mortality. Therefore, it is important to avoid both premature extubation and unnecessary prolongation of MV. Although some studies have determined the predictors of early weaning success and failure, only a few have investigated these factors in critically ill surgical patients who require postoperative MV. The aim of this study was to evaluate predictors of early weaning failure from MV in critically ill patients who had undergone emergency gastrointestinal (GI) surgery.The medical records of 3327 adult patients who underwent emergency GI surgery between January 2007 and December 2016 were reviewed retrospectively. Clinical and laboratory parameters before surgery and within 2 days postsurgery were investigated.This study included 387 adult patients who required postoperative MV. A low platelet count (adjusted odds ratio [OR]: 0.995; 95% confidence interval [CI]: 0.991-1.000; P = .03), an elevated delta neutrophil index (DNI; adjusted OR: 1.025; 95% CI: 1.005-1.046; P = .016), a delayed spontaneous breathing trial (SBT; adjusted OR: 14.152; 95% CI: 6.571-30.483; P < .001), and the presence of postoperative shock (adjusted OR: 2.436; 95% CI: 1.138 5.216; P = .022) were shown to predict early weaning failure from MV in the study population.Delayed SBT, a low platelet count, an elevated DNI, and the presence of postoperative shock are independent predictors of early weaning failure from MV in critically ill patients after emergency GI surgery. PMID- 30290687 TI - Complications of percutaneous liver biopsy in living donor liver transplantation: Two case reports. AB - RATIONALE: According to previously published studies, major complications arising from a percutaneous liver biopsy are rare and occur in less than 0.1% of cases. This report describes an approach to percutaneous liver biopsy that can help avoid damage to the liver in a living donor liver transplantation (LDLT) setting. PATIENT CONCERNS: Case 1: In the first case a donor percutaneous liver biopsy (PLB) of both lobes of the liver was performed for pre-LDLT evaluation. The ultrasonography (US)-guided epigastric right-angle approach and an automatic one handed cocking disposable 18G biopsy gun was used to puncture the left liver lobe to determine the presence of fatty liver. A penetrating liver injury occurred, accompanied by massive bloody ascites (about 700 cc) and subcapsular hematoma at the left lateral segment. The bleeding was managed by bi-polar coagulation during the transplant and the following liver donation procedure proceeded smoothly without any subsequent complications. Case 2: In the second case, selective right lobe PLB for clinical assessment after LDLT was performed in the recipient. Hemorrhagic shock occurred following a puncture of the right posterior branch of the right hepatic artery when using the biopsy-gun via the right lateral intercostal approach. DIAGNOSES: Extravasation was documented by angiography and emergent transhepatic arterial embolization was performed. INTERVENTION: Extravasation was documented by angiography and emergent transhepatic arterial embolization with glue:lipiodol (1:4) was performed to stop bleeding. OUTCOMES: The recipient survived after medical management. LESSONS: To prevent complications, the right-angle approach of PLB may be changed to an oblique angle using a one-fire biopsy-gun. Use of a manual Menghini's needle should be considered for left lobe liver biopsies. Since US-guided manual Menghini's needle for PLB can be observed with the needle tip inserted in the liver, needle mediated compromising of the major vessels or biliary tree can be prevented, and it does not penetrate the liver again. A superficial puncture less than 0.5 cm away from the liver surface should be made during right lobe liver biopsy. This approach can help to avoid damage to the hepatic artery. PMID- 30290688 TI - A low abundance of Bifidobacterium but not Lactobacillius in the feces of Chinese children with wheezing diseases. AB - BACKGROUND: The intestinal microbiota is linked with allergic reaction diseases. However, the difference in the fecal microbiota composition between sensitized wheezy and nonsensitized subjects in Chinese children remains unknown. The aim of this study was to quantitate the amounts of fecal microbiota in wheezy children, and to explore the correlation between fecal microbiota and serum Th1/Th2/Th17 type cytokines and total IgE in these patients. METHODS: The amounts of Bifidobacterium and Lactobacillus were determined using a 16S-RNA real-time polymerase chain reaction (PCR) method in wheezy children (cases) and nonwheezy controls. Serum Th1/Th2/Th17-type cytokines levels were measured using flow a cytometric bead array assay. In addition, the concentrations of total serum IgE was also determined. RESULTS: In comparison with that in the healthy control (HC), significantly lower abundance of Bifidobacterium and lower levels of Th1 cytokines (IFN-gamma and TNF-alpha), but higher levels of Th2-type cytokines (IL 4, IL-5) and Th17-type (IL-17A) cytokine were detected in children with bronchiolitis and asthma. But there was no significant difference in the amounts of Lactobacillus. Interestingly, the amounts of fecal Bifidobacterium were correlated positively with serum Th1 cytokines IFN-gamma, and correlated negatively with serum Th17 cytokines IL-17A, Th2 cytokines IL-4 and serum total IgE in these patients. CONCLUSIONS: Our findings demonstrated that lower quantity of Bifidobacterium, but not Lactobacillus, may be correlated with asthma and bronchiolitis in chinese children. These results also may provide guidance in choosing the proper probiotics for wheezing children. PMID- 30290689 TI - Supra-inguinal fascia iliaca block under ultrasound guidance for perioperative analgesia during bipolar hip arthroplasty in a patient with severe cardiovascular compromise: A case report. AB - RATIONALE: The relief of selective hip pain may be difficult to attain. Therefore, a deep nerve block such as epidural anesthesia or lumbar plexus nerve block is required. However, deep nerve blocks may not be possible in patients with complications, including severe cardiovascular disease. PATIENTS CONCERNS: The patient in our report had coronary stents inserted previously and required continuous anticoagulant therapy owing to severe heart failure. DIAGNOSIS: Bipolar hip arthroplasty was required in our patient because of a fracture of the neck of femur on the left side. INTERVENTIONS: We decided to perform the surgery using a fascia iliaca block (block of the femoral and the lateral femoral cutaneous nerves) by the suprainguinal approach. The fascia iliaca nerve block was performed under ultrasound guidance, using 20 mL of levobupivacaine. OUTCOMES: The surgery was performed successfully with adequate sensory block around the hip region. LESSONS: Ultrasound-guided fascia iliaca nerve block by the supra-inguinal approach may be an effective anesthetic technique for patients undergoing surgery for fracture of the neck of femur.

AB - Drug dependence, which can exist concurrently with chronic pain, is seen as one of the major causes of rapidly increasing medical expenses. However, drug dependence in patients with chronic pain has not been evaluated. The aim of this study was to identify the risk factors for drug dependence in patients with chronic noncancer pain.This retrospective study included 151 patients with chronic noncancer pain (43 males, 108 females; mean age, 72 years). Low back pain (LBP) occurred in 96 patients, whereas 22 had shoulder pain, 8 had hip pain, and 77 had knee pain. Patients were divided into drug dependence and nondrug dependence groups based on the Severity of Dependence Scale (SDS) scores. Patients with SDS scores >=5 and <5 were classified into drug dependence and nondrug dependence groups, respectively. All patients completed self-report questionnaires. Factors that predict drug dependence were identified by performing univariate and multivariate analyses.Sixty (40%) of the 151 patients met the SDS criteria for drug dependence. Significant differences were found between patients with and without drug dependence for the LBP, hip pain, number of medications, and for the Numerical Rating Scale, Pain Disability Assessment Scale (PDAS), Hospital Anxiety and Depression Scale, and Pain Catastrophizing Scale (PCS) scores. Multiple regression analysis identified LBP, hip pain, PCS, and PDAS scores as factors related to drug dependence in patients with chronic noncancer pain.Drug dependence tends to differ in patients based on the location of their chronic pain. Pain catastrophizing and disability indicated a greater tendency for drug dependence. Thus, PCS and PDAS scores are useful screening tools for predicting drug dependence in patients with chronic pain.

AB - AIM: To identify the main predictors of the enlargement of ascending aorta and to assess the possible relation between reduced bone mineral density and a diameter of ascending aorta in the specific Turner syndrome (TS) population. METHODS: 50 adult females diagnosed with TS have been enrolled into the cross-sectional study. Dimensions of ascending aorta have been measured in four positions using thoracic magnetic resonance imaging, aortic size index (ASI) has been calculated. BMD has been assessed on dual - energy - X ray absorptiometry (DXA) in 1 - 4 lumbar vertebrae and neck of the femur. According to Z score on DXA two groups have been formed: a group of patients with normal BMD and a group with reduced BMD. Metabolic parameters and the measurements of ascending aorta have been compared between the two groups. RESULTS: Extremely high rate of the dilatation of the root of aorta (up to 50 %) was identified in this study. The larger ASI has been found in patients with reduced BMD, negative relation between BMD and ASI has been identified, although after the adjustment for SHRT this correlation remained insignificant. In the multivariate analysis, the main factors affecting ASI were age, body surface area and bicuspid aortic valve. CONCLUSIONS: The main factors associated with the enlargement of ascending aorta in Turner syndrome were age, body surface area and bicuspid aortic valve, the relation between diameter of ascending aorta and bone mineral density was not identified.

AB - INTRODUCTION: Cervical spondylotic myelopathy (CSM) most commonly occurs at the C3-7 levels and is successfully treated by multilevel anterior cervical discectomy and fusion (ACDF) or cervical laminectomy and fusion (CLF), but no procedure has clearly demonstrated superiority. Most prior investigations comparing approaches are limited by marked heterogeneity in the composition of the study groups. This investigation compares ACDF versus CLF surgery specifically at C3-7 in terms of long-term neurological outcome and the fate of the adjacent levels. METHODS: Over a twelve-year period, surgeries to treat CSM at C3-7 by ACDF or CLF were retrospectively reviewed. Demographic/clinical data were recorded, pre/post- operative modified Japanese orthopedic association scores (mJOA) were calculated, and any complications were noted. RESULTS: Of 781 cervical surgery patients, 15 underwent C3-7 ACDF and 49 CLF. There were no differences in patient characteristics or pre/postoperative mJOA scores. Mean follow-up was 52 and 44 months for the anterior and posterior groups respectively. A complication occurred in 3/15 (21%) of the anterior and 14/49 (28%) of the posterior group. No infections occurred in ACDF patients, but there were three in CLF patients. Pseudoarthrosis occurred in two ACDF patients, neither associated with symptoms. Four in the CLF group had asymptomatic pseudoarthroses; two others needed reoperation for kyphosis at the inferior level. CONCLUSIONS: Long-term neurological improvement occurs following C3-7 ACDF and CLF to a similar degree. While not statistically significant, fewer complications, were seen following ACDF. The absence of symptomatic adjacent segment degeneration (ASD) following ACDF in this series raises a question for further study whether the statistical likelihood of ASD changes once the C3-7 levels are already fused.

AB - Brain mapping techniques (intraoperative neurophysiology and intraoperative neuropsychology) represent the gold standard in glioma surgery; these techniques have been proven to be the gold standard in glioma resection. From the introduction of MRI in clinical routine, several advanced applications have been developed like functional MRI and tractography based on diffusion imaging. Both techniques have application in glioma surgery. The fMRI allows to identify cortical areas related to a specific function, DTI allow to reconstruct a model of the sub-cortical connectivity. This paper describes the clinical application of fMRI and DTI tractography, enlightening sensitivity and specificity in comparison to gold standard and underlining their limitation in surgical decision making.

AB - Survey data from a comprehensive national survey of ~34 000 households were analyzed for the mix status and transition trajectory of energy for boiling water in rural Chinese households from 1992 to 2012. In 1992, ~6% of households reported using electricity, biogas, or liquefied petroleum gas (LPG) to boil drinking water; in 2012, the proportion was ~60%. Income per capita appeared most strongly associated with this transition toward electricity and other clean fuels. Median annual incomes for households using biomass fuels, electric kettles, and LPG were RMB 15 000, 28 000, and 30 000, respectively. Overall, the transition was most pronounced in eastern China, a region which experienced relatively higher rates of economic growth over the same 20-year period. Energy type preferences appear to be highly dependent on fuel accessibility such that coal and straw usage was higher in provinces with higher coal and grain production. These trends suggest that electric kettle use would likely increase from ~29% (2012) to ~60% by 2030, at which point <5% of rural households would be expected to boil with solid fuels. Recent evidence suggests that this transition could contribute to reductions in water-related gastrointestinal illness as well as reductions in air pollutant emissions in rural China.

AB - INTRODUCTION: Remote communities across Australia lack the ready access to medical care generally afforded to metropolitan populations. The Royal Flying Doctor Service (RFDS) medical chest program provides medical resources to these communities allowing medications to be dispensed in conjunction with a telehealth consulting service. More than 3000 medical chests are located throughout Australia and each year the Queensland RFDS conducts approximately 20 000 telehealth consultations. The aim of this study was to review the use of the medical chest model within the state of Queensland and to analyse changes in the medical chest program from 10 years earlier to evaluate the changing healthcare needs of remote Australian populations. METHODS: All telehealth consultations and items dispensed from the medical chests were reviewed over a 1-year period from 1 July 2013 and 30 June 2014. Items dispensed were categorised and compared to those in 2005-06 in absolute terms by one-way ANOVA and proportionately by chi2 with Fisher's exact test. Consultations using the medical chest were categorised and compared to those in 2005-06 by chi2 with Fisher's exact test. RESULTS: The number of telehealth consultations conducted in 2013-14 (N=20 707) was not different to the number conducted in 2005-06 (N=21 470). Fewer items were dispensed from the medical chests in 2013-14 (3936 total items) than in 2005-06 (8607 total items; p<0.0001). In the specific categories of 'burns and other dressings' and 'antihistamines', the number of individual items dispensed increased. Resources from the medical chest were used more for genitourinary system consultations and less for consultations involving specific infectious diseases; the circulation, respiratory and abdominal systems; skin diseases; injury; symptoms without a diagnosis; and following other contact with a health service. CONCLUSIONS: The medical chests remain a vital tool for medical care of remote populations and the need for telehealth medical advice remains unchanged, although fewer items are being dispensed. The use of the medical chest for each diagnostic category of consultation has shown some variation over the past 10 years, reflective of changing patterns of accident, injury and disease.

AB - INTRODUCTION: The Rural Primary Health Services Delivery Project aims to improve the quality and coverage of health services to rural populations in Papua New Guinea. There are limitations in measuring performance of such projects through analysis of health information system data alone due to data quality issues and a multitude of unmeasured factors that affect performance. A mixed methods study was undertaken to understand the contextual factors that affect health service performance. METHODS: A performance assessment framework was developed including service delivery indicators derived from the National Health Information System. Prior to implementation, a baseline analysis of the indicators was undertaken. Subsequently, semi-structured interviews were conducted with health administrators, in which they were asked about factors they perceived to influence health facility performance. During the interviews, key informants were provided with health indicators for their province and asked to interpret the performance of facilities. Interviews were transcribed and inductive thematic analysis performed. RESULTS: Performance indicators varied greatly within and between districts. Key informants cited a number of reasons for this variation. Health facilities accessible by road in urban areas, with competent and/or higher level staff and health services operated by churches or private companies, were cited as contributors to high performance. For high performing districts, key informants also discussed use of health information, planning and targeted strategies to improve performance. Inadequate numbers of staff, poorly skilled staff, funding delays and challenging geography were major contributors noted for poor performance. CONCLUSION: Analysis of quantitative indicators needs to be performed at health facility level in order to understand district level performance. Interpretation of performance through key informant interviews provided useful insight into previously undocumented contextual factors affecting health delivery performance. The sequential explanatory mixed methods design could be applied to evaluations of other health service delivery programs in similar contexts.

AB - INTRODUCTION: An accurate diagnostic classification of thyroid lesions remains an important clinical aspect that needs to be addressed in order to avoid 'diagnostic' thyroidectomies. Among the several 'omics' techniques, proteomics is playing a pivotal role in the search for diagnostic markers. In recent years, different approaches have been used, taking advantage of the technical improvements related to mass spectrometry that have occurred. Areas covered: The review provides an update of the recent findings in diagnostic classification, in genetic definition and in the investigation of thyroid lesions based on different proteomics approaches and on different type of specimens: cytological, surgical and biofluid samples. A brief section will discuss how these findings can be integrated with those obtained by metabolomics investigations. Expert commentary: Among the several proteomics approaches able to deepen our knowledge of the molecular alterations of the different thyroid lesions, MALDI-MSI is strongly emerging above all. In fact, MS-imaging has also been demonstrated to be capable of distinguishing thyroid lesions, based on their different molecular signatures, using cytological specimens. The possibility to use the material obtained by the fine needle aspiration makes MALDI-MSI a highly promising technology that could be implemented into the clinical and pathological units. PMID- 30290701 TI - Increased use of illicit drugs in a Dutch cluster headache population. AB - Introduction Many patients with cluster headache report use of illicit drugs. We systematically assessed the use of illicit drugs and their effects in a well defined Dutch cluster headache population. Methods In this cross-sectional explorative study, 756 people with cluster headache received a questionnaire on lifetime use and perceived effects of illicit drugs. Results were compared with age and sex-matched official data from the Dutch general population. Results Compared to the data from the general population, there were more illicit drug users in the cluster headache group (31.7% vs. 23.8%; p < 0.01). Reduction in attack frequency was reported by 56% (n = 22) of psilocybin mushroom, 60% (n = 3) of lysergic acid diethylamide and 50% (n = 2) of heroin users, and a decreased attack duration was reported by 46% (n = 18) of PSI, 50% (n = 2) of heroin and 36% (n = 8) of amphetamine users. Conclusion In the Netherlands, people with cluster headache use illicit drugs more often than the general population. The question remains whether this is due to an actual alleviatory effect, placebo response, conviction, or common pathophysiological background between cluster headache and addictive behaviours such as drug use. PMID- 30290702 TI - The effectiveness of interventions targeting physical activity and/or sedentary behaviour in people with Multiple Sclerosis: a systematic review. AB - BACKGROUND: Remaining physically active is important to maintain functional ability and reduce the incidence of co-morbidities in people with Multiple Sclerosis. The aim of this review was to evaluate the effectiveness of interventions on physical activity or sedentary behaviour in people with Multiple Sclerosis. METHODS: A systematic search was conducted in May 2018 of the following databases: Web of Science Core Collections, Embase and Medline. Included studies were randomised controlled trials involving people with Multiple Sclerosis who completed an intervention, compared to any comparator. Outcomes included subjective or objective measures of physical activity or sedentary behaviour. Quality assessment was performed using the Physiotherapy Evidence Database scale. RESULTS: Twenty-five trials were included covering 1697 participants, the majority of which had mild-moderate disability (average Physiotherapy Evidence Database score 6.2 +/- 1.5). Experimental interventions included exercise prescription (n = 5), behaviour change interventions (n = 10), combined exercise, and behaviour change techniques (n = 7) and education (n = 3). Generally, subjective but not objective physical activity improved in those with mild-moderate disability. Insufficient data existed on the effectiveness on sedentary behaviour. CONCLUSIONS: A discrepancy seems to exists between the effectiveness of physical activity interventions in people with Multiple Sclerosis depending on whether physical activity was assessed objectively or subjectively, with the latter indicating effects. Effects on sedentary behaviour remain to be elucidated. Implications for Rehabilitation Remaining physically active is important to maintain functional ability, independence, quality of life, and to reduce the incidence of co-morbidity. Exercise prescription, behaviour change interventions, combined exercise and behaviour change interventions, and health promotion education appear to subjectively improve physical activity in people with Multiple Sclerosis with mild-moderate disability, yet this is often not the case when measured objectively. There is a lack of evidence to support the effectiveness of these interventions on sedentary behaviour. PMID- 30290703 TI - Factors influencing middle managers' commitment to the implementation of innovations in cancer care. AB - Objective To identify and illuminate influences on middle managers' commitment to innovation implementation. Methods A qualitative study was conducted, employing the methods of grounded theory. Semi-structured interviews were used to collect data from middle managers (n = 15) in Nova Scotia and New Brunswick, Canada. Data were collected and analysed concurrently, using an inductive constant comparative approach. Data collection and analysis continued until theoretical saturation was reached. Results The data revealed middle managers contemplate two central issues in terms of their commitment to implementation, that is whether or not they fully engage in and support the implementation of a particular innovation. These issues are (1) ease of implementation and (2) potential benefit for patients. Middle managers' views and expectations related to ease of implementation are influenced by available resources, fit with setting, and stakeholder buy-in. Their views on patient benefit are influenced by external evidence of benefit and local gaps in care. Conclusions These findings provide further insight into the factors that influence middle managers' commitment to innovation implementation, and how middle managers consider these factors in the context of their work settings.

AB - : Formation of the autolysosome involves SNARE-mediated autophagosome-lysosome fusion, which is mediated by a combination of the Qa SNARE STX17 (syntaxin 17), the Qbc SNARE SNAP29 and the R-SNAREs VAMP7/8. 2 very recent reports have now implicated another R-SNARE with a longin domain, YKT6, in this fusion process. Interestingly, these reports painted two different pictures of YKT6's involvement. Studies in HeLa cells indicated that YKT6, acting independently of STX17, could form a separate SNARE complex with SNAP29 and another Qa SNARE to mediate autophagosome-lysosome fusion. Conversely, work in Drosophila larvae fat cells showed that while Ykt6 could form a SNARE complex with Snap29 and Syx17/Stx17, it is readily outcompeted by lysosomal Vamp7 in this regard. Moreover, its activity in autophagosome-lysosome fusion is not impaired by mutation of the supposedly critical ionic zero-layer residue from R to Q. In this regard, YKT6 may therefore act in a noncanonical way to regulate fusion. Here, we ponder on the fresh mechanistic perspectives on the final membrane fusion step of macroautophagy/autophagy offered by these new findings. Further, we propose another possible mechanism as to how YKT6 might act, which may provide some reconciliation to the differences observed. ABBREVIATIONS: LD: longin domain. PMID- 30290707 TI - The cargo receptor SQSTM1 ameliorates neurofibrillary tangle pathology and spreading through selective targeting of pathological MAPT (microtubule associated protein tau). AB - Accumulating evidence suggests that misfolded MAPT (microtubule associated protein tau), the main component of neurofibrillary tangles in tauopathies, is subject to degradation by the autophagy-lysosomal pathway. Selective autophagy is a subtype of macroautophagy that requires cargo receptors, such as OPTN (optineurin) or SQSTM1, to recognize specific targets for their sequestration within the autophagosome and their eventual degradation by the lysosome, although their roles in targeting distinct MAPT species have not been fully investigated. Using cargo receptor knockout cell lines and a seeding-based cellular assay in which neurofibrillary tangle pathology can be modeled in vitro, we reveal that while OPTN primarily targets soluble MAPT expressed in physiological conditions, SQSTM1 predominantly degrades insoluble but not soluble mutant MAPT. Endogenous SQSTM1 colocalizes with misfolded and aggregated MAPT species in vitro and in vivo, and both this colocalization and its function in MAPT clearance require both the LC3-interacting region (LIR) motif and also the PB1 self-polymerization domain of SQSTM1. Further, pathogenic MAPT accumulation reduces basal macroautophagy/autophagy in vitro and is associated with a compensatory upregulation of the lysosomal pathway in vivo. Finally, increased expression of SQSTM1 in MAPT transgenic mouse brains ameliorates MAPT pathology and prion-like spreading. Our results uncover distinct properties of selective autophagy receptors in targeting different MAPT species, implicate compromised autophagy as a potential underlying factor in mutant MAPT deposition, and demonstrate a potent and specific role of SQSTM1 in targeted clearance of pathogenic MAPT, through which it blocks neurofibrillary tangle accumulation and pathological spreading.

However, STX17 is not absolutely required for fusion because STX17 knockout cells partially retain autophagosome-lysosome fusion activity. We recently identified YKT6, an R-SNARE, as another autophagosomal SNARE protein that acts independently of STX17 in mammals. Here, we discuss the features and functions of autophagosomal SNARE proteins by comparing STX17 and YKT6.

PMID- 30290709 TI - Therapeutic response to glucocorticoids, anticoagulation and plasma exchange in a patient with primary antiphospholipid syndrome presenting with purpura fulminans. AB - We report the case of a 25-year-old female patient who presented with purpura fulminans as a manifestation of primary antiphospholipid syndrome. Purpura fulminans is considered a rare cutaneous manifestation of antiphospholipid syndrome. Most frequently, it occurs in the context of catastrophic antiphospholipid syndrome and is associated with significant morbidity and mortality, either due to loss of affected extremities or thromboembolic damage to internal organs. After insufficient efficacy of parenteral anticoagulation and oral glucocorticosteroid treatment, we escalated treatment to high-dose intravenous glucocorticosteroid and five consecutive sessions of plasma exchange with good and sustained clinical response. At follow-up six months after admission, skin manifestations had healed with scarring, and no additional thrombotic events had occurred. Plasma exchange may hold promise as a therapeutic option in refractory or severe cases of antiphospholipid syndrome-related purpura fulminans with extensive cutaneous necrosis, although evidence is limited. PMID- 30290710 TI - Endovascular retrograde approach may be a better option for acute tandem occlusions stroke. AB - Objective The endovascular treatment strategy for acute tandem occlusion stroke is challenging, and controversy exists regarding which lesion should be treated first. This study addresses the uncertainty regarding the priority choice for thrombectomy in acute anterior circulation tandem occlusion stroke. Methods We analysed the clinical and angiographic data of tandem stroke patients who underwent interventional therapy from the endovAsCular Treatment of acUte Anterior circuLation ischaemic stroke (ACTUAL) registry. Recanalisation was assessed according to the modified thrombolysis in cerebral infarction score. Clinical outcome was evaluated at 90 days using the modified Rankin scale score. Results Sixty tandem occlusion stroke patients were enrolled. Thirty-one (51.7%) patients received anterograde therapy, while 29 (48.3%) patients underwent the retrograde approach. Successful recanalisation (modified thrombolysis in cerebral infarction score 2b-3) occurred in 78.3% (47/60) of patients, and 50.0% (30/60) of patients achieved a modified Rankin scale score of 0-2 at 90 days. Patients undergoing the retrograde approach spent less time in distal occlusion recanalisation (125 (86-167) vs. 95 (74-122) minutes; P = 0.04) and achieved better functional outcomes at 90 days (69.0% (20/29) vs. 32.3% (10/31); P = 0.004) than patients who received anterograde therapy. The retrograde approach was associated with favourable clinical outcomes (odds ratio 0.21; 95% confidence interval 0.07-0.64; P = 0.006). Conclusion For acute tandem occlusion stroke, favourable outcomes were better in patients undergoing retrograde therapy than in patients who received the anterograde approach. Future randomised trials are warranted to determine the optimal treatment. PMID- 30290711 TI - pH-dependent regulation of SQSTM1/p62 during autophagy. AB - During macroautophagy/autophagy, SQSTM1/p62 plays dual roles as a key mediator of cargo selection and as an autophagic substrate. SQSTM1 links N-degrons and/or ubiquitinated cargoes to the autophagosome by forming homo- or hetero-oligomers, although its N-degron recognition and oligomerization mechanisms are not well characterized. We recently found that SQSTM1 is a novel type of N-recognin whose ZZ domain provides a negatively-charged binding pocket for Arg-charged N-degron (Nt-Arg), a prototype type-1 substrate. Although differences in binding affinity exist for each N-degron, SQSTM1 also interacts with type-2 N-degrons, such as Nt Tyr and Nt-Trp. Intriguingly, interactions between SQSTM1's ZZ domain and various N-degrons are greatly influenced by pH-dependent SQSTM1 oligomerization via its PB1 domain. Because cellular pH conditions vary from neutral to acidic depending on the stage of autophagy, the pH-dependent regulation of SQSTM1's oligomerization must be tightly coupled with the autophagic process. PMID- 30290713 TI - Exploring lateralization during memory through hemispheric pre-activation: Differences based on the stimulus type. AB - The original approach of the Hemispheric Encoding/Retrieval Asymmetry model (HERA) was aimed at the operations of encoding and retrieving episodic memories. However, whether HERA presumptions can apply to different types of stimuli (e.g., words and pictures) continues to be a matter of debate. Therefore, in order to analyse the effects of brain pre-activation on subsequent memory, HERA was tested through a hand-clenching paradigm using four types of stimuli: words, fractal images, silhouettes of common objects, and pseudowords. Results revealed that only the memory of words and pseudowords was enhanced by hand-clenching pre activation, according to HERA predictions. Since the cognitive processes underlying recognition of verbal stimuli are considered to follow a cognitive route involving grapheme-morpheme conversion, it could be hypothesized that hand clenching pre-activation might be associated with a selective pre-activation of the brain circuits participating in that pathway. Hence, the present work broadens possible interpretations behind the effects of hand-clenching on memory, based on the process engaged and the type of stimulus to be remembered. PMID- 30290715 TI - Procalcitonin as an early indicator of urosepsis following prostate biopsy. AB - BACKGROUND: To investigate the usefulness of serum procalcitonin (PCT) in the early diagnosis of urinary tract infection (UTI) and urosepsis following transrectal prostate biopsy. METHODS: In this prospective observational study, 227 patients who underwent transrectal ultrasound-guided prostate biopsy were evaluated. The relationship between urosepsis and age, serum PCT, C-reactive protein, prostate-specific antigen (PSA), prostate volume, PSA density and pathologic results following biopsy was assessed. Serum PCT level was measured in all patients immediately before the biopsy and at the post-biopsy day 2. RESULTS: Of the 227 patients, 11 (4.8%) developed UTI with positive urine culture without urosepsis and 5 (2.2%) developed urosepsis within 30 days after biopsy. The concentration of PCT was within the normal range before the biopsy. Procalcitonin concentration at post-biopsy day 2 was significantly higher in patients who developed urosepsis (1.91 +/- 2.99 ng/ml vs. 0.05 +/- 0.08 ng/ml; p = .004) compared with non-UTI patients. Only elevated PCT level at post-biopsy day 2 was a statistically significant independent predictor of post-biopsy urosepsis. The area under the ROC curve for the prediction of urosepsis was 0.976 (95%CI: 0.941 1.000) and a cut-off 0.095 ng/ml in the level of PCT at post-biopsy day 2 yielded a sensitivity of 100% and specificity of 93.8% in detecting urosepsis following biopsy. CONCLUSIONS: Procalcitonin appears to be a useful early biomarker to predict the urosepsis following prostate biopsy. Patients with elevated PCT value should be closely monitored after the biopsy. PMID- 30290714 TI - PRKN-regulated mitophagy and cellular senescence during COPD pathogenesis. AB - : Cigarette smoke (CS)-induced accumulation of mitochondrial damage has been widely implicated in chronic obstructive pulmonary disease (COPD) pathogenesis. Mitophagy plays a crucial role in eliminating damaged mitochondria, and is governed by the PINK1 (PTEN induced putative protein kinase 1)-PRKN (parkin RBR E3 ubiquitin protein ligase) pathway. Although both increased PINK1 and reduced PRKN have been implicated in COPD pathogenesis in association with mitophagy, there are conflicting reports for the role of mitophagy in COPD progression. To clarify the involvement of PRKN-regulated mitophagy in COPD pathogenesis, prkn knockout (KO) mouse models were used. To illuminate how PINK1 and PRKN regulate mitophagy in relation to CS-induced mitochondrial damage and cellular senescence, overexpression and knockdown experiments were performed in airway epithelial cells (AEC). In comparison to wild-type mice, prkn KO mice demonstrated enhanced airway wall thickening with emphysematous changes following CS exposure. AEC in CS-exposed prkn KO mice showed accumulation of damaged mitochondria and increased oxidative modifications accompanied by accelerated cellular senescence. In vitro experiments showed PRKN overexpression was sufficient to induce mitophagy during CSE exposure even in the setting of reduced PINK1 protein levels, resulting in attenuation of mitochondrial ROS production and cellular senescence. Conversely PINK1 overexpression failed to recover impaired mitophagy caused by PRKN knockdown, indicating that PRKN protein levels can be the rate-limiting factor in PINK1-PRKN-mediated mitophagy during CSE exposure. These results suggest that PRKN levels may play a pivotal role in COPD pathogenesis by regulating mitophagy, suggesting that PRKN induction could mitigate the progression of COPD.

AB - Cancer stem cells (CSC) are thought to be an important source of cancer cells in tumors of different origins. Mounting evidence suggests they are generated reversibly from existing cancer cells, and supply new cancer cells during tumor progression and following therapy. Elegant lineage mapping stud(ies are identifying progenitors, and in some cases differentiated cells, as targets of transformation in a variety of tumors. Recent evidence suggests resulting tumor initiating cells (TIC) might be distinct from CSC. Molecular pathways leading from cells of tumor origin to precancerous lesions and cancer cells are only beginning to be unraveled. We review a pathway where asymmetric division of precancerous cells generates TIC in a K-Ras-initiated model of lung cancer. And, we compare unexpected steps in this asymmetric division to those evident in well studied stem cell models. PMID- 30290716 TI - Resolution of large aortic valve vegetations in antiphospholipid syndrome treated with therapeutic anticoagulation: a report of two cases and literature review. AB - Non-bacterial thrombotic endocarditis in antiphospholipid syndrome presents a management dilemma. Large mobile valvular lesions pose an increased risk of stroke and arterial embolization. However, surgical excision or valve replacement in such patients carries high morbidity and mortality, while anticoagulation alone has limited data. We describe two patients with antiphospholipid syndrome presenting with neurologic events and large non-bacterial aortic valve vegetations. Both patients were successfully managed with anticoagulation and demonstrated rapid dissolution of lesions without evidence of recurrent embolic events. We provide a literature review describing additional cases managed with anticoagulation with dissolution of valvular lesions over time. Our cases further support the efficacy and safety of anticoagulation in patients with antiphospholipid syndrome and non-bacterial thrombotic endocarditis in the context of arterial embolization. PMID- 30290717 TI - Therapeutic potential of allogeneic mesenchymal stromal cells transplantation for lupus nephritis. AB - Animal and human studies have suggested the potential of mesenchymal stromal cells (MSCs) to treat systemic lupus erythematosus (SLE). Here, we present the results of compassionate MSC treatments for three SLE patients to provide the proof of concept for a randomized and controlled clinical trial. Three patients of different ethnicities who suffer from chronic SLE, and who presented with class IV active proliferative nephritis confirmed by biopsy, were treated with allogeneic MSCs from healthy donors. Ninety million cells were infused intravenously into each patient during high and very high activity disease flare ups and follow-up was continued for 9 months. Multi-organic affectation was quantified by the SLE disease activity index (SLEDAI), and indicators of lupus nephritis activity, such as proteinuria, as well as lymphocyte and monocyte antigens and anti-HLA antibodies were measured at 1, 3, 6, and 9 months after treatment. Proteinuria levels improved dramatically during the 1st month after treatment and the ameliorations were sustained throughout the follow-up period. SLEDAI scores revealed early, durable, and substantial remissions that were complete for two patients and partial for the third patient and that permitted medication doses to be reduced 50-90%. These favourable outcomes support completion of the randomized and controlled MSC trial for SLE. PMID- 30290718 TI - RAB30 regulates PI4KB (phosphatidylinositol 4-kinase beta)-dependent autophagy against group A Streptococcus. AB - Macroautophagy/autophagy plays an important role in the immune response to invasion by intracellular pathogens such as group A Streptococcus (GAS; Streptococcus pyogenes). We previously identified RAB30, a Golgi-resident GTPase, as a novel anti-bacterial autophagic regulator in the formation of GAS-containing autophagosome-like vacuoles (GcAVs); however, the precise mechanism underlying this process remains elusive. Here, we elucidate a novel property of RAB30: the ability to recruit PI4KB (phosphatidylinositol 4-kinase beta) to the Golgi apparatus and GcAVs. We found that trans-Golgi network (TGN) vesicles were incorporated into GcAVs via RAB30 to promote GcAV formation. Moreover, depletion of phosphatidylinositol-4-phosphate (PtdIns4P), a phosphatidylinositol enriched in the TGN, by wortmannin and phenylarsine oxide, followed by subsequent repletion with exogenous PtdIns4P revealed that PtdIns4P is crucial for GcAV formation. Furthermore, we identify an interaction between RAB30 and PI4KB, in which the knockdown of RAB30 decreased the localization of PI4KB to the TGN and GcAVs. Finally, PI4KB knockout suppressed autophagy by inhibiting GcAV formation, resulting in the increased survival of GAS. Our results demonstrate a novel autophagosomal formation mechanism involving coordinative functions of RAB30 and PI4KB distinct from those utilized in canonical autophagy.

PMID- 30290719 TI - MITF-MIR211 axis is a novel autophagy amplifier system during cellular stress. AB - Macroautophagy (autophagy) is an evolutionarily conserved recycling and stress response mechanism. Active at basal levels in eukaryotes, autophagy is upregulated under stress providing cells with building blocks such as amino acids. A lysosome-integrated sensor system composed of RRAG GTPases and MTOR complex 1 (MTORC1) regulates lysosome biogenesis and autophagy in response to amino acid availability. Stress-mediated inhibition of MTORC1 results in the dephosphorylation and nuclear translocation of the TFE/MITF family of transcriptional factors, and triggers an autophagy- and lysosomal-related gene transcription program. The role of family members TFEB and TFE3 have been studied in detail, but the importance of MITF proteins in autophagy regulation is not clear so far. Here we introduce for the first time a specific role for MITF in autophagy control that involves upregulation of MIR211. We show that, under stress conditions including starvation and MTOR inhibition, a MITF-MIR211 axis constitutes a novel feed-forward loop that controls autophagic activity in cells. Direct targeting of the MTORC2 component RICTOR by MIR211 led to the inhibition of the MTORC1 pathway, further stimulating MITF translocation to the nucleus and completing an autophagy amplification loop. In line with a ubiquitous function, MITF and MIR211 were co-expressed in all tested cell lines and human tissues, and the effects on autophagy were observed in a cell-type independent manner. Thus, our study provides direct evidence that MITF has rate-limiting and specific functions in autophagy regulation. Collectively, the MITF-MIR211 axis constitutes a novel and universal autophagy amplification system that sustains autophagic activity under stress conditions.

AB - Background and purpose A direct aspiration first pass technique involves first line aspiration to remove the thrombus through a large-bore aspiration catheter in large vessel strokes. The aim of this study was to assess safety and clinical outcomes with a direct aspiration first pass technique using the new ARC catheter. Methods A retrospective analysis of prospectively collected data from three university hospitals was performed between June 2016 and May 2018. The following parameters of all acute ischemic stroke interventions using the ARC catheter were analyzed: use of intravenous thrombolysis, National Institutes of Health Stroke Scale scores at presentation and discharge, successful reperfusion (modified Thrombolysis in Cerebral Infarction 2b-3), procedure duration, procedure-related complications and 90-day clinical outcome (modified Rankin Scale score). Results In total, 41 patients were included in the study and anterior circulation occlusion was noted in 35 (85%). The median National Institutes of Health Stroke Scale at admission was 18 and prior intravenous thrombolysis was administered in 35 patients (85%). Only six (15%) patients required the use of a rescue stent retriever. Successful reperfusion was achieved in 40 patients (98%) with a median procedure time of 32 minutes. No catheter related complications were observed. Symptomatic intracerebral hemorrhage occurred in one patient (2%). Median National Institutes of Health Stroke Scale at discharge was 3; 49% were independent and 10% died at 90 days. Conclusions In the present study, the ARC catheter allowed a 98% successful reperfusion rate. The complication rate was in line with those of previous a direct aspiration first pass technique publications. PMID- 30290721 TI - RNase Y-mediated regulation of the streptococcal pyrogenic exotoxin B. AB - Endoribonuclease Y (RNase Y) is a crucial regulator of virulence in Gram-positive bacteria. In the human pathogen Streptococcus pyogenes, RNase Y is required for the expression of the major secreted virulence factor streptococcal pyrogenic exotoxin B (SpeB), but the mechanism involved in this regulation remains elusive. Here, we demonstrate that the 5' untranslated region of speB mRNA is processed by several RNases including RNase Y. In particular, we identify two RNase Y cleavage sites located downstream of a guanosine (G) residue. To assess whether this nucleotide is required for RNase Y activity in vivo, we mutated it and demonstrate that the presence of this G residue is essential for the processing of the speB mRNA 5' UTR by RNase Y. Although RNase Y directly targets and processes speB, we show that RNase Y-mediated regulation of speB expression occurs primarily at the transcriptional level and independently of the processing in the speB mRNA 5' UTR. To conclude, we demonstrate for the first time that RNase Y processing of an mRNA target requires the presence of a G. We also provide new insights on the speB 5' UTR and on the role of RNase Y in speB regulation. PMID- 30290722 TI - Fatal gastric distension in a gold thioglucose mouse model of obesity. AB - This case report addresses the problem of underreporting negative results and adverse side effects in animal testing. We present our findings regarding a hyperphagic mouse model associated with unforeseen high mortality. The results outline the necessity of reporting detailed information in the literature to avoid duplication. Obese mouse models are essential in the study of obesity, metabolic syndrome and diabetes mellitus. An experimental model of obesity can be induced by the administration of gold thioglucose (GTG). After transcending the blood-brain barrier, the GTG molecule interacts with regions of the ventromedial hypothalamus, thereby primarily targeting glucose-sensitive neurons. When these neurons are impaired, mice become insensitive to the satiety effects of glucose and develop hyperphagia. In a pilot study for optimising dosage and body weight development, C57BL/6 mice were treated with GTG (0.5 mg/g body weight) or saline, respectively. Animals were provided a physiological amount of standard diet (5 g per animal) for the first 24 hours after treatment to prevent gastric dilatation. Within 24 hours after GTG injection, all GTG-treated animals died of gastric overload and subsequent circulatory shock. Animals developed severe attacks of hyperphagia, and as the amount of provided chow was restricted, mice exhibited unforeseen pica and ingested bedding material. These observations strongly suggest that restricted feeding is contraindicated concerning GTG application. Presumably, the impulse of excessive food intake was a strong driving force. Therefore, the actual degree of suffering in the GTG-induced model of hyperphagia should be revised from moderate to severe. PMID- 30290723 TI - Improved care and support for people in mental health crisis. AB - District nurses are increasingly required to manage the physical health needs of patients who misuse substances or have mental health problems. Some patients have a mental health crisis in the community and come to the attention of the police. Concern over the use of police powers to detain people in a mental health crisis and in particular the use police cells as a place of safety has led to changes in the law. In this article the author updates district nurses on the amendments to police powers under the Mental Health Act 1983 introduced by the Policing and Crime Act 2017, part 4 chapter 4 designed to better manage those people experiencing a mental health crisis.

AB - An increasing number of people require insulin to manage their diabetes, many of them in supported environments such as residential care homes. Community nursing teams are likely to have a growing caseload of care home residents who require diabetes care, including insulin injections, and many unregistered practitioners are being asked to take on this role. If community nurse leads, matrons, frailty teams and pharmacy teams work together to provide training to staff in care homes (particularly unregistered practitioners), diabetes care can be improved. This has to be suitable for groups and for people with different levels of understanding, and supported by written resources. Courses are interactive to engage and motivate all learners, and methods of teaching include group work, visual teaching aids and games. Self-assessment around competencies, using a competency framework, not only demonstrates the development of staff but also highlights key areas of diabetes care.

Technology integrated health management (TIHM) for dementia is part of the NHS England National Test Bed Programme and has involved trailing the deployment of network enabled devices combined with artificial intelligence to improve outcomes for people with dementia and their carers. TIHM uses machine learning and complex algorithms to detect and predict early signs of ill health. The premise is if changes in a person's health or routine can be identified early on, support can be targeted at the point of need to prevent the development of more serious complications.

PMID- 30290729 TI - Supporting student nurses who have their first clinical placement in the community nursing team. AB - First year student nurses are increasingly undertaking their first placement with community nurses. The importance of how this initial learning experience is introduced by the higher education institution, as well as how the student is welcomed and integrated into the community nursing team, cannot be underestimated. Following positive anonymous feedback from students, which indicated that they had benefitted from the introduction, welcome and integration they experienced, the university and mentors reviewed how this had been done to identify good practice to share with colleagues. Students indicated that their welcome and integration had helped them to feel part of the team and enhanced learning, because they were so well supported, and mentors had facilitated learning experiences by acknowledging that this was their first placement experience. It is notable that mentors were committed to the students' learning and used workplace social capital to optimise the student experience. At a time when retention of students is essential to increase the future workforce, mentors dedicated to student learning are acting as ambassadors for the community workforce, and may well encourage students to have a career in community nursing.

AB - Frailty is a term that presents many difficulties for policy makers and clinicians due to the lack of consensus in defining frailty in a way that meets the needs of older people. A principle-based concept analysis was used to examine the scientific literature across four perspectives: medicine, nursing, social sciences, and occupational and physiotherapy. The purpose was to identify the conceptual components of frailty as revealed by analysis of the literature, and to develop a theoretical definition of frailty. The findings exposed commonalities in implied meanings both within and across perspectives. The strengths of frailty as a concept are revealed in the implications for clinical practice and relevance to health professionals. The limitations reflect a concept that is still evolving and further research is recommended but this should not stop health professionals engaging in this process. The definition developed in this study will enhance existing knowledge and promote a shared understanding to unite different disciplines in recognising frailty as an important concept.

AB - The maternal population in the UK has become an increasingly challenging group of patients to manage. Women with pre-existing and often complex medical conditions are successfully conceiving. Most physicians will have had some involvement in the care of obstetric patients admitted with medical problems, and a lack of experience and fear of causing harm may result in essential investigations and treatment being withheld. The physiological changes in pregnancy can complicate the interpretation of observations and test results. This article discusses the presentation of commonly encountered medical problems in the obstetric population, including breathlessness, chest pain, palpitations, seizure and headache. It covers specific investigations and suggested treatment in this subset of patients. These women should receive the same level of care and attention as those who are not pregnant. Early diagnosis and effective management can help to reduce maternal morbidity and mortality caused by medical problems arising during pregnancy.

AB - This article explains the approach to managing a patient with herpes simplex virus encephalitis. Acute encephalopathy is a common and often intimidating presentation in an acute general medical setting. Application of key principles will enable the generalist to take life-saving action before obtaining any specialist input. Viral infection is the most common cause (48.2%) of encephalitis; another large group is cases of autoimmune aetiology. Early diagnosis of encephalitis is crucial to ensure that the right treatment is given on time. Guidelines on the management of viral encephalitis were published by the British Association of Neurologists and British Infection Association ( Solomon et al, 2012 ), but adherence to these standards by clinicians has been found to be suboptimal ( Han and Coebergh, 2017 ). This puts lives in danger, in the context of a treatable, serious, acute presentation. Although viral infection is the most common cause of encephalitis, an awareness of rarer forms of autoimmune encephalitis is necessary. The differential diagnosis of autoimmune encephalitis is important because the disease is potentially treatable with immunosuppressive agents. Paraneoplastic limbic encephalitis may present months or years before the detection of a tumour. PMID- 30290745 TI - Use of antiretroviral drugs to prevent the transmission and acquisition of HIV.

They were first introduced by Light and Pillemer in 1984 . In scientific literature, funnel plots are used to identify the probability of bias in meta-analyses and compare institutional performance. The ability to identify variation is better with graphical than tabular display. In addition, the way data are presented can directly influence the interpretation of results. This was demonstrated by Marshall et al (2004) , who presented institutional mortality data in both a league table and control chart format. This study illustrated that when displayed as a league table, a greater number of units were identified for investigation than were actually required. The use of control charts or funnel plots may therefore show benefit in reducing the number of inappropriately labelled outliers. This article explains how clinicians should read and interpret funnel plots, and discusses their considerations and limitations.

PMID- 30290753 TI - Trauma radiology in the UK: an overview. AB - NHS Choices defines 'major trauma' as multiple, serious injuries that could result in disability or death. Worldwide, trauma is the leading cause of death and disability in people under 40 years of age. The National Audit Office estimates that there are at least 20 000 major trauma cases in England every year, resulting in 5400 deaths and leaving many others with serious permanent disability. Because the incidence of trauma is particularly high in younger patients, an average of 36 life years is lost for every trauma death ( Chaira and Cimbanassi, 2003 ). The landscape in major trauma imaging has evolved over the last 30 years, and this review chronicles these changes and the reasons for them, and looks at how the current guidelines have been formulated.

PMID- 30290756 TI - Prevalence of sarcopenia and its components in community-dwelling outpatient older adults and their relation with functionality. AB - AIM: Sarcopenia is recognized with its adverse functional outcomes. We aimed to report the prevalence of European Working Group on Sarcopenia in Older People (EWGSOP) defined sarcopenia and its individual components in community dwelling outpatient older adults and study the correlations of EWGSOP defined sarcopenia, muscle mass, muscle strength, and physical performance with functional status. MATERIAL AND METHODS: The subjects were prospectively recruited from the geriatrics outpatient clinics of our university hospital. Body composition was assessed with bioimpedance analysis. Muscle strength was assessed by measurement of hand grip strength with hydraulic hand dynamometer, physical performance was assessed by 4 meter usual gait speed (UGS). Impaired muscle function was defined as presence of low muscle strength and or slow gait speed. As a measure of functionality, modified version of Katz activities of daily living (ADL) and Lawton instrumental activities of daily living (IADL) were assessed. RESULTS: A total of 242 community dwelling outpatients with mean age of 79.4 +/- 5.7 years were enrolled. 31.8% were male. Prevalence of low muscle mass was 2.1% and impaired muscle function was 71.1%. Prevalence of EWGSOP defined sarcopenia was 0.8% (1.3% in men and 0.6% in women). Most correlated parameter with ADL and IADL was the usual gait speed (r = 0.49, r = 0.63; p < .001, respectively). Grip strength was also correlated with ADL and IADL (r = 0.28, r = 0.35; p < .001). However, the skeletal muscle mass index (SMMI) was not correlated with ADL, IADL (p = .22, p = .22, respectively). In regression analysis, both ADL score and IADL scores were most related to UGS (beta = 0.5 and 0.6, p < .001), age (beta = -0.25 and -0.2, p < .001) and then sarcopenia (beta = 0.1 and 0.1, p < .05) but was not related to hand grip strength or SMMI. CONCLUSIONS: The prevalence of sarcopenia was low as 0.8% albeit the presence of impaired muscle function in more than 2/3 of the cases. We have found that EWGSOP defined sarcopenia had association with ADL and IADL. The gait speed component of sarcopenia had the strongest associations with functional measures but SMMI component did not have any relation. We suggest that although low muscle mass may be a parameter related to worse functionality, it should not be regarded prerequisite for presence of sarcopenia analogous to low bone mineral density for osteoporosis. PMID- 30290757 TI - Gene expression profiling of postnatal lung development in the marsupial gray short-tailed opossum (Monodelphis domestica) highlights conserved developmental pathways and specific characteristics during lung organogenesis. AB - BACKGROUND: After a short gestation, marsupials give birth to immature neonates with lungs that are not fully developed and in early life the neonate partially relies on gas exchange through the skin. Therefore, significant lung development occurs after birth in marsupials in contrast to eutherian mammals such as humans and mice where lung development occurs predominantly in the embryo. To explore the mechanisms of marsupial lung development in comparison to eutherians, morphological and gene expression analysis were conducted in the gray short tailed opossum (Monodelphis domestica). RESULTS: Postnatal lung development of Monodelphis involves three key stages of development: (i) transition from late canalicular to early saccular stages, (ii) saccular and (iii) alveolar stages, similar to developmental stages overlapping the embryonic and perinatal period in eutherians. Differentially expressed genes were identified and correlated with developmental stages. Functional categories included growth factors, extracellular matrix protein (ECMs), transcriptional factors and signalling pathways related to branching morphogenesis, alveologenesis and vascularisation. Comparison with published data on mice highlighted the conserved importance of extracellular matrix remodelling and signalling pathways such as Wnt, Notch, IGF, TGFbeta, retinoic acid and angiopoietin. The comparison also revealed changes in the mammalian gene expression program associated with the initiation of alveologenesis and birth, pointing to subtle differences between the non functional embryonic lung of the eutherian mouse and the partially functional developing lung of the marsupial Monodelphis neonates. The data also highlighted a subset of contractile proteins specifically expressed in Monodelphis during and after alveologenesis. CONCLUSION: The results provide insights into marsupial lung development and support the potential of the marsupial model of postnatal development towards better understanding of the evolution of the mammalian bronchioalveolar lung. PMID- 30290759 TI - Intra and interrater reliability and clinical feasibility of a simple measure of cervical movement sense in patients with neck pain. AB - BACKGROUND: Pattern tracing tasks can be used to assess cervical spine movement sense (CMS). A simple clinical measure of CMS (tracing fixed figure-of-eight (F8) and zigzag (ZZ) patterns with a head mounted laser) has been proposed and assessed in asymptomatic subjects. It is important to determine if examiner ratings of the traces are reliable and feasible for clinical use in those with neck pain. We therefore examined the intra- and inter-rater reliability of rating video recordings of the CMS tasks, and the feasibility of undertaking the tests in clinic by comparing slow motion versus real-time video ratings. METHODS: Cross sectional study examining neck pain subjects from a physiotherapy clinic. F8 and ZZ patterns traced with a head-mounted laser pointer at two velocities (accurate; accurate & fast) were videoed and later examined. Time (total time taken to complete the pattern), error frequency (number of deviations) and error magnitude (sum of deviations multiplied by distance from the central line) were measured. Two assessors independently evaluated the laser tracing videos in slow motion; a third rated the videos in real time. Intraclass correlation coefficients (ICC) and standard error of measurements (SEM) were calculated for intra- and inter tester reliability, and feasibility. RESULTS: Twenty neck pain patient (13 women) videos were assessed. Intra-and inter-rater reliability was substantial to almost perfect (ICC 0.76-1.00; SEM < 0.01-2.50). Feasibility was moderate to almost perfect (ICC 0.54-1; SEM < 0.01-2.98). CONCLUSIONS: Video (slow motion) ratings of time and errors for F8 and ZZ movement patterns in neck pain subjects showed high intra and inter-rater reliability. Achieving reliable ratings in clinic (real-time) appears feasible. Synthesising our results, the most reliable and feasible CMS ratings appear to be when the subject uses accurate rather than accurate and fast execution. The ZZ movement pattern may be superior to F8 in terms of rating. Time and error frequency for tracing F8 and ZZ as accurately as possible in determining CMS appears promising for use in clinic. Future research directions were identified. PMID- 30290758 TI - A draft genome of the striped catfish, Pangasianodon hypophthalmus, for comparative analysis of genes relevant to development and a resource for aquaculture improvement. AB - BACKGROUND: The striped catfish, Pangasianodon hypophthalmus, is a freshwater and benthopelagic fish common in the Mekong River delta. Catfish constitute a valuable source of dietary protein. Therefore, they are cultured worldwide, and P. hypophthalmus is a food staple in the Mekong area. However, genetic information about the culture stock, is unavailable for breeding improvement, although genetics of the channel catfish, Ictalurus punctatus, has been reported. To acquire genome sequence data as a useful resource for marker-assisted breeding, we decoded a draft genome of P. hypophthalmus and performed comparative analyses. RESULTS: Using the Illumina platform, we obtained both nuclear and mitochondrial DNA sequences. Molecular phylogeny using the mitochondrial genome confirmed that P. hypophthalmus is a member of the family Pangasiidae and is nested within a clade including the families Cranoglanididae and Ictaluridae. The nuclear genome was estimated at approximately 700 Mb, assembled into 568 scaffolds with an N50 of 14.29 Mbp, and was estimated to contain ~ 28,600 protein coding genes, comparable to those of channel catfish and zebrafish. Interestingly, zebrafish produce gadusol, but genes for biosynthesis of this sunscreen compound have been lost from catfish genomes. The differences in gene contents between these two catfishes were found in genes for vitamin D-binding protein and cytosolic phospholipase A2, which have lost only in channel catfish. The Hox cluster in catfish genomes comprised seven paralogous groups, similar to that of zebrafish, and comparative analysis clarified catfish lineage-specific losses of A5a, B10a, and A11a. Genes for insulin-like growth factor (IGF) signaling were conserved between the two catfish genomes. In addition to identification of MHC class I and sex determination-related gene loci, the hypothetical chromosomes by comparison with the channel catfish demonstrated the usefulness of the striped catfish genome as a marker resource. CONCLUSIONS: We developed genomic resources for the striped catfish. Possible conservation of genes for development and marker candidates were confirmed by comparing the assembled genome to that of a model fish, Danio rerio, and to channel catfish. Since the catfish genomic constituent resembles that of zebrafish, it is likely that zebrafish data for gene functions is applicable to striped catfish as well.

However, these methods are time-consuming with low diagnostic accuracy and micro metastases might be missed. In this study, we aim to evaluate detection of metastatic cells in draining lymph nodes by flow cytometry. METHODS: To assess the sensitivity of micro-metastasis detection by FACS (Fluorescence-activated cell sorting), HeLa cells were titrated into Peripheral blood mononuclear cells (PBMCs) and expression of pan-cytokeratin AE1/AE3 was analyzed. Single cell suspensions were separately prepared from 10 regional lymph nodes obtained from 5 patients with invasive penile cancer undergoing radical surgery and lymph node dissection. Lymph node dereived cells were examined for cell surface expression of EpCAM, E-cadherin and intracellular expression of pan-cytokeratin AE1/AE3 by FACS. RESULTS: Ten lymph nodes from 5 penile cancer patients were investigated in a head-to-head comparison between FACS and pathology examination of sections. All metastatic lymph nodes verified by pathology examination were also identified by FACS. Two additional lymph nodes with micro-metastases were diagnosed by FACS only. CONCLUSIONS: FACS analyses of pan-cytokeratin AE1/AE3 stained single cells from tumor draining lymph nodes can be used to detect micro-metastases in patients with penile cancer patients. PMID- 30290762 TI - Three dimensional evaluation of soft tissue after orthognathic surgery. AB - BACKGROUND: To evaluate the nasolabial soft tissue change three-dimensionally after orthognathic surgery, using a structured light scanner. METHODS: Thirty-two malocclusion patients, who underwent orthognathic surgery, were evaluated. CBCT and 3D facial scans were obtained before surgery and 3 months after surgery. The 3D changes in the 26 landmarks, and the relative ratio of the soft tissue movement to the bony movement, were evaluated. RESULTS: In the Le Fort I advancement patients, the nasal tip moved 17% forward, compared to the maxillary bony movement, but the nasal prominence decreased 15%. The alar width increased 4 mm after the advancement, and the width decreased 4.7 mm after Le Fort I setback. The relative ratio of the soft tissue movement to the bony movement after bilateral sagittal split osteotomy was about 66% at the Li point in the anteroposterior direction, and it was 21% in the Le Fort I advancement and 14% in Le Fort I setback at the Ls point. CONCLUSION: Alar cinch suturing may not be sufficient to overcome the effect of the maxilla advancement compressing the nasal complex. Alar width widening was prevented in Le Fort I setback. However, it is uncertain that the alar cinch suturing was solely responsible. The soft tissue around the mandible tends to accompany the bony movement more than the maxillary area. In addition, structured light scanning system proved to be a useful tool to evaluate the nasolabial soft tissue. PMID- 30290761 TI - Tunneling nanotubes evoke pericyte/endothelial communication during normal and tumoral angiogenesis. AB - BACKGROUND: Nanotubular structures, denoted tunneling nanotubes (TNTs) have been described in recent times as involved in cell-to-cell communication between distant cells. Nevertheless, TNT-like, long filopodial processes had already been described in the last century as connecting facing, growing microvessels during the process of cerebral cortex vascularization and collateralization. Here we have investigated the possible presence and the cellular origin of TNTs during normal brain vascularization and also in highly vascularized brain tumors. METHODS: We searched for TNTs by high-resolution immunofluorescence confocal microscopy, applied to the analysis of 20-um, thick sections from lightly fixed, unembedded samples of both developing cerebral cortex and human glioblastoma (GB), immunolabeled for endothelial, pericyte, and astrocyte markers, and vessel basal lamina molecules. RESULTS: The results revealed the existence of pericyte derived TNTs, labeled by proteoglycan NG2/CSPG4 and CD146. In agreement with the described heterogeneity of these nanostructures, ultra-long (> 300 um) and very thin (< 0.8 um) TNTs were observed to bridge the gap between the wall of distant vessels, or were detected as short (< 300 um) bridging cables connecting a vessel sprout with its facing vessel or two apposed vessel sprouts. The pericyte origin of TNTs ex vivo in fetal cortex and GB was confirmed by in vitro analysis of brain pericytes, which were able to form and remained connected by typical TNT structures. CONCLUSIONS: None of the multiple roles described for TNTs can be excluded from a possible involvement during the processes of both normal and pathological vessel growth. A possible function, suggested by the pioneering studies made during cerebral cortex vascularization, is in cell searching and cell-to-cell recognition during the processes of vessel collateralization and vascular network formation. According to our results, it is definitely the pericyte-derived TNTs that seem to actively explore the surrounding microenvironment, searching for (site-to-site recognition), and connecting with (pericyte-to-pericyte and/or pericyte-to-endothelial cell communication), the targeted vessels. This idea implies that TNTs may have a primary role in the very early phases of both physiological and tumor angiogenesis in the brain. PMID- 30290763 TI - Involvement of K+ATP and Ca2+ channels in hydrogen sulfide-suppressed ageing of porcine oocytes. AB - BACKGROUND: Hydrogen sulfide has been shown to improve the quality of oocytes destined for in vitro fertilization. Although hydrogen sulfide is capable of modulating ion channel activity in somatic cells, the role of hydrogen sulfide in gametes and embryos remains unknown. Our observations confirmed the hypothesis that the KATP and L-type Ca2+ ion channels play roles in porcine oocyte ageing and revealed a plausible contribution of hydrogen sulfide to the modulation of ion channel activity. RESULTS: We confirmed the benefits of the activation and suppression of the KATP and L-type Ca2+ ion channels, respectively, for the preservation of oocyte quality. CONCLUSIONS: Our experiments identified hydrogen sulfide as promoting the desired ion channel activity, with the capacity to protect porcine oocytes against cell death. Further experiments are needed to determine the exact mechanism of hydrogen sulfide in gametes and embryos. PMID- 30290764 TI - Genome-wide association scan for heterotic quantitative trait loci in multi-breed and crossbred beef cattle. AB - BACKGROUND: Heterosis has been suggested to be caused by dominance effects. We performed a joint genome-wide association analysis (GWAS) using data from multi breed and crossbred beef cattle to identify single nucleotide polymorphisms (SNPs) with significant dominance effects associated with variation in growth and carcass traits and to understand the mode of action of these associations. METHODS: Illumina BovineSNP50 genotypes and phenotypes for 11 growth and carcass traits were available for 6796 multi-breed and crossbred beef cattle. After performing quality control, 42,610 SNPs and 6794 animals were used for further analyses. A single-SNP GWAS for the joint association of additive and dominance effects was conducted in purebred, crossbred, and combined datasets using the ASReml software. Genomic breed composition predicted from admixture analyses was included in the mixed effect model to account for possible population stratification and breed effects. A threshold of 10% genome-wide false discovery rate was applied to declare associations as significant. The significant SNPs with dominance association were mapped to their corresponding genes at 100 kb. RESULTS: Seven SNPs with significant dominance associations were detected for birth weight, weaning weight, pre-weaning daily gain, yearling weight and marbling score across the three datasets at a false discovery rate of 10%. These SNPs were located on bovine chromosomes 1, 3, 4, 6 and 21 and mapped to six putative candidate genes: U6atac, AGBL4, bta-mir-2888-1, REPIN1, ICA1 and NXPH1. These genes have interesting biological functions related to the regulation of gene expression, glucose and lipid metabolism and body fat mass. For most of the identified loci, we observed over-dominance association with the studied traits, such that the heterozygous individuals at any of these loci had greater genotypic values for the trait than either of the homozygous individuals. CONCLUSIONS: Our results revealed very few regions with significant dominance genetic effects across all the traits studied in the three datasets used. Regarding the SNPs that were detected with dominance associations, further investigation is needed to determine their relevance in crossbreeding programs assuming that dominance effects are the main cause of (or contribute usefully to) heterosis. PMID- 30290765 TI - Modified Robert Jones bandage can not reduce postoperative swelling in enhanced recovery after primary total knee arthroplasty without intraoperative tourniquet: a randomized controlled trial. AB - BACKGROUND: Compression therapy is commonly used to reduce lower limb swelling and blood loss after knee surgery. This study was performed to investigate whether modified Robert Jones bandage (MRJB) as a postoperative compression therapy is necessary for enhanced-recovery primary total knee arthroplasty without the tourniquet application. METHODS: In this prospective randomized controlled trial, 90 patients were grouped into 2 groups randomly. The experimental group received compression therapy with MRJB from toes to thigh for 24 h and the control group received no compression therapy. Knee swelling, blood loss, range of motion (ROM), pain, patient reported comfort level and complications were recorded. RESULTS: No significant differences were observed between the two groups when we compared knee swelling. Similarly, no significant difference on postoperative blood loss, pain, ROM, complications was found. However, patients in control group had significantly higher comfort ratings than compression group during the first 24 h. CONCLUSIONS: MRJB is not routinely indicated in enhanced-recovery primary total knee arthroplasty without tourniquet application. TRIAL REGISTRATION: The trial was registered in the Chinese Clinical Trial Registry ( ChiCTR-INR-16010177 ) dated 18th December 2016. PMID- 30290766 TI - Impact of cardiac catheterization timing and contrast media dose on acute kidney injury after cardiac surgery. AB - BACKGROUND: The association between pre-operative cardiac catheterization and cardiac surgery associated acute kidney injury (CSA-AKI) has been reported inconsistently. The purpose of this study is to evaluate the effect of the catheterization timing and contrast media dose on the incidence of postoperative acute kidney injury. METHODS: Patients who underwent cardiac catheterization and cardiac surgery successively from January 2015 to December 2015 were prospectively enrolled in this study. The primary outcome was CSA-AKI which was defined as the Kidney Disease: Improving Global Outcomes Definition and Staging (KDIGO) criteria. Univariate analysis and multivariate regression were performed to identify the predictors for CSA-AKI. Baseline characteristics were balanced with propensity score method for better adjustment. RESULTS: A total of 1069 consecutive eligible patients were enrolled into this study. The incidence of CSA AKI and AKI requiring renal replacement therapy (AKI-RRT) were 38.5% (412/1069) and 1.9% (20/1069) respectively. Preoperative estimated glomerular filtration rate less than 60 mL/min/1.73m2 (OR = 2.843 95% CI 1.374-5.882), the time interval between catheterization and surgery<=7 days (OR = 2.546, 95% CI 1.548 4.189) and the dose of contrast media (CM) > 240 mg/kg (OR = 2.490, 95%CI 1.392 4.457) were identified as predictors for CSA-AKI. In the patients with the dose of CM > 240 mg/kg, the incidence of CSA-AKI was higher in patients who underwent cardiac catheterization <=7 days before cardiac surgery than in those of > 7 days before cardiac surgery (39.4% vs. 28.8%, p = 0.025). The longer interval of more than 7 days was revealed to be inversely associated with CSA-AKI through logistic regression (OR = 0.579, 95% CI 0.337-0.994). CONCLUSION: Catheterization within 7 days of cardiac surgery and a dose of CM > 240 mg/kg were associated with the onset of CSA-AKI. For patients who received a dose of CM > 240 mg/kg, postponing the cardiac surgery is potentially beneficial to reduce the risk of CSA-AKI. PMID- 30290767 TI - Involvement of a dihydrodipicolinate synthase gene (FaDHDPS1) in fungal development, pathogenesis and stress responses in Fusarium asiaticum. AB - BACKGROUND: Dihydrodipicolinate synthase (DHDPS) is an allosteric enzyme, which catalyzes the first unique step of lysine biosynthesis in prokaryotes, higher plants and some fungi. To date, the biological roles of DHDPS in filamentous fungi are poorly understood. RESULTS: In this study, on the basis of comparative genome resequencing, a DHDPS gene was found to be specific in Fusarium asiaticum, named FaDHDPS1, which showed high amino acid identity to that of entomopathogenic fungus. Subcellular localization of the FaDHDPS1-GFP fusion protein was mainly concentrated in the cytoplasm of conidia and dispersed in the cytoplasm during conidial germination. To reveal the biological functions, both deletion and complementation mutants of FaDHDPS1 were generated. The results showed that the FaDHDPS1 deletion mutant was defective in conidiation, virulence and DON biosynthesis. In addition, deletion of FaDHDPS1 resulted in tolerance to sodium pyruvate, lysine, low temperature and Congo red. CONCLUSION: Results of this study indicate that FaDHDPS1 plays an important role in the regulation of vegetative differentiation, pathogenesis and adaption to multiple stresses in F. asiaticum. PMID- 30290768 TI - Potentially inappropriate medication use among hypertensive older African American adults. AB - BACKGROUND: Inappropriate use of medications, particularly among minority older adults with co-morbidity, remains a major public health concern. The American Geriatrics Society (AGS) reports that Potentially Inappropriate Medication (PIM) continues to be prescribed for older adults, despite evidence of poor outcomes. The main objective of this study was to examine the prevalence of PIM use among underserved non-institutionalized hypertensive older African-American adults. Furthermore, this study examines potential correlations between PIM use and the number and type of chronic conditions. METHODS: This cross-sectional study is comprised of a convenience sample of 193 hypertensive non-institutionalized African-American adults, aged 65 years and older recruited from several senior housing units located in underserved areas of South Los Angeles. The updated 2015 AGS Beers Criteria was used to identify participants using PIMs. RESULTS: Almost one out of two participants had inappropriate medication use. While the average number of PIMs taken was 0.87 drugs, the range was from one to seven medications. Almost 23% of PIMs were due to drugs with potential drug-drug interactions. The most common PIM was the use of proton pump inhibitors (PPI) and Central Nervous System (CNS) active agents. Nearly 56% of PIMs potentially increased the risk of falls and fall-associated bone fractures. The use of PIMs was significantly higher among participants who reported a higher number of chronic conditions. Nearly 70% of participants with PIM use reported suffering from chronic pain. CONCLUSIONS: The major reason for high levels of polypharmacy, PIMs, and drug interactions is that patients suffer from multiple chronic conditions. But it may not be possible or necessary to treat all chronic conditions. Therefore, the goals of care should be explicitly reviewed with the patient in order to determine which of the many chronic conditions has the greatest impact on the life goals and/or functional priorities of the patient. Those drugs that have a limited impact on the patient's functional priorities and that may cause harmful drug-drug interactions can be reduced or eliminated, while the remaining medications can focus on the most important functional priorities of the patient. PMID- 30290769 TI - Missed opportunities in antenatal care for improving the health of pregnant women and newborns in Geita district, Northwest Tanzania. AB - BACKGROUND: Despite the significant benefits of early detection and management of pregnancy related complications during antenatal care (ANC) visits, not all pregnant women in Tanzania initiate ANC in a timely manner. The primary objectives of this research study in rural communities of Geita district, Northwest Tanzania were: 1) to conduct a population-based study that examined the utilization and availability of ANC services; and 2) to explore the challenges faced by women who visited ANC clinics and barriers to utilization of ANC among pregnant women. METHODS: A sequential explanatory mixed method design was utilized. Household surveys that examined antenatal service utilization and availability were conducted in 11 randomly selected wards in Geita district. One thousand, seven hundred and nineteen pregnant women in their 3rd trimester participated in household surveys. It was followed by focus group discussions with community health workers and pregnant women that examined challenges and barriers to ANC. RESULTS: Of the pregnant women who participated, 86.74% attended an ANC clinic at least once; 3.62% initiated ANC in the first trimester; 13.26% had not initiated ANC when they were interviewed in their 3rd trimester. Of the women who had attended ANC at least once, the majority (82.96%) had been checked for HIV status, less than a half (48.36%) were checked for hemoglobin level, and only a minority had been screened for syphilis (6.51%). Among women offered laboratory testing, the prevalence of HIV was 3.88%, syphilis, 18.57%, and anemia, 54.09%. In terms of other preventive measures, 91.01% received a tetanus toxoid vaccination, 76.32%, antimalarial drugs, 65.13%, antihelminthic drugs, and 76.12%, iron supplements at least once. Significant challenges identified by women who visited ANC clinics included lack of male partner involvement, informal regulations imposed by health care providers, perceived poor quality of care, and health care system related factors. Socio-cultural beliefs, fear of HIV testing, poverty and distance from health clinics were reported as barriers to early ANC utilization. CONCLUSION: Access to effective ANC remains a challenge among women in Geita district. Notably, most women initiated ANC late and early initiation did not guarantee care that could contribute to better pregnancy outcomes. PMID- 30290770 TI - Genome-wide analysis of the plant-specific PLATZ proteins in maize and identification of their general role in interaction with RNA polymerase III complex. AB - BACKGROUND: PLATZ proteins are a novel class of plant-specific zinc-dependent DNA binding proteins that are classified as transcription factors (TFs). However, their common biochemical features and functions are poorly understood. RESULT: Here, we identified and cloned 17 PLATZ genes in the maize (Zea mays) genome. All ZmPLATZs were located in nuclei, consistent with their predicted role as TFs. However, none of ZmPLATZs was found to have intrinsic activation properties in yeast. Our recent work shows that FL3 (ZmPLATZ12) interacts with RPC53 and TFC1, two critical factors in the RNA polymerase III (RNAPIII) transcription complex. Using the yeast two-hybrid assay, we determined that seven other PLATZs interacted with both RPC53 and TFC1, whereas three had no protein-protein interaction with these two factors. The other six PLATZs interacted with either RPC53 or TFC1. These findings indicate that ZmPLATZ proteins are generally involved in the modulation of RNAPIII-mediated small non-coding RNA transcription. We also identified all of the PLATZ members in rice (Oryza sativa) and Arabidopsis thaliana and constructed a Maximum likelihood phylogenetic tree for ZmPLATZs. The resulting tree included 44 members and 5 subfamilies. CONCLUSIONS: This study provides insight into understanding of the phylogenetic relationship, protein structure, expression pattern and cellular localization of PLATZs in maize. We identified nine and thirteen ZmPLATZs that have protein protein interaction with RPC53 and TFC1 in the current study, respectively. Overall, the characterization and functional analysis of the PLATZ family in maize will pave the way to understanding RNAPIII-mediated regulation in plant development. PMID- 30290771 TI - Decoupling photo- and thermoperiod by projected climate change perturbs bud development, dormancy establishment and vernalization in the model tree Populus. AB - BACKGROUND: The performance and survival of deciduous trees depends on their innate ability to anticipate seasonal change. A key event is the timely production of short photoperiod-induced terminal and axillary buds that are dormant and freezing-tolerant. Some observations suggest that low temperature contributes to terminal bud initiation and dormancy. This is puzzling because low temperatures in the chilling range universally release dormancy. It also raises the broader question if the projected climate instabilities, as well as the northward migration of trees, will affect winter preparations and survival of trees. RESULTS: To gauge the response capacity of trees, we exposed juvenile hybrid aspens to a 10-h short photoperiod in combination with different day/night temperature regimes: high (24/24 degrees C), moderate (18/18 degrees C), moderate-low (18/12 degrees C) and low (12/12 degrees C), and analysed bud development, dormancy establishment, and marker gene expression. We found that low temperature during the bud formation period (pre-dormancy) upregulated dormancy-release genes of the gibberellin (GA) pathway, including the key GA biosynthesis genes GA20oxidase and GA3oxidase, the GA-receptor gene GID1, as well as GA-inducible enzymes of the 1,3-beta-glucanase family that degrade callose at plasmodesmal Dormancy Sphincter Complexes. Simultaneously, this pre-dormancy low temperature perturbed the expression of flowering pathway genes, including CO, FT, CENL1, AGL14, LFY and AP1. In brief, pre-dormancy low temperature compromised bud development, dormancy establishment, and potentially vernalization. On the other hand, a high pre-dormancy temperature prevented dormancy establishment and resulted in flushing. CONCLUSIONS: The results show that pre-dormancy low temperature represents a form of chilling that antagonizes dormancy establishment. Combined with available field data, this indicates that natural Populus ecotypes have evolved to avoid the adverse effects of high and low temperatures by initiating and completing dormant buds within an approximate temperature-window of 24-12 degrees C. Global warming and erratic temperature patterns outside this range can therefore endanger the successful propagation of deciduous perennials. PMID- 30290772 TI - Discovery of rare ancestry-specific variants in the fetal genome that confer risk of preterm premature rupture of membranes (PPROM) and preterm birth. AB - BACKGROUND: Preterm premature rupture of membranes (PPROM) is the leading identifiable cause of preterm birth, a complication that is more common in African Americans. Attempts to identify genetic loci associated with preterm birth using genome-wide association studies (GWAS) have only been successful with large numbers of cases and controls, and there has yet to be a convincing genetic association to explain racial/ethnic disparities. Indeed, the search for ancestry specific variants associated with preterm birth has led to the conclusion that spontaneous preterm birth could be the consequence of multiple rare variants. The hypothesis that preterm birth is due to rare genetic variants that would go undetected in standard GWAS has been explored in the present study. The detection and validation of these rare variants present challenges because of the low allele frequency. However, some success in the identification of fetal loci/genes associated with preterm birth using whole genome sequencing and whole exome sequencing (WES) has recently been reported. While encouraging, this is currently an expensive technology, and methods to leverage the sequencing data to quickly identify and cost-effectively validate variants are needed. METHODS: We developed a WES data analysis strategy based on neonatal genomic DNA from PPROM cases and term controls that was unencumbered by preselection of candidate genes, and capable of identifying variants in African Americans worthy of focused evaluation to establish statistically significant associations. RESULTS: We describe this approach and the identification of damaging nonsense variants of African ancestry in the DEFB1 and MBL2 genes that encode anti-microbial proteins that presumably defend the fetal membranes from infectious agents. Our approach also enabled us to rule out a likely contribution of a predicted damaging nonsense variant in the METTL7B gene. CONCLUSIONS: Our findings support the notion that multiple rare population-specific variants in the fetal genome contribute to preterm birth associated with PPROM. PMID- 30290774 TI - Impact of the epidermal growth factor receptor mutation status on the prognosis of recurrent adenocarcinoma of the lung after curative surgery. AB - BACKGROUND: The prognosis of patients with epidermal growth factor receptor (EGFR) mutant adenocarcinoma of the lung (Mt) and EGFR wild-type adenocarcinoma (Wt) after complete resection of the lung differ; however, the mechanisms responsible for these differences remain unclear. The present study examined the post-operative prognosis of recurrent pulmonary adenocarcinoma patients to evaluate the clinicopathological nature of Mt and contribution of EGFR - tyrosine kinase inhibitors (TKI) to the prognosis of patients. METHODS: The subjects were 237 patients with recurrent pulmonary adenocarcinoma who underwent EGFR mutation analysis, and consisted of 108 patients with recurrent Mt and 129 with recurrent Wt. Multivariate analyses were performed to investigate whether the EGFR status is a prognostic factor for relapse-free survival (RFS) and post-relapse survival (PRS). RESULTS: RFS was significantly better in Mt than in Wt patients; median RFS were 20.2 and 13.3 months, respectively (p < 0.001). The multivariate analysis identified EGFR mutation as an independent prognostic factor for a favorable RFS (hazard ratio = 0.68; 95% confidence interval, 0.52-0.89). Although, no significant differences were observed in PRS between Mt and Wt patients (median PRS were 33.9 and 28.2 months, respectively; p = 0.360), PRS was significantly better in Mt with EGFR - TKI than in Wt and Mt patients without EGFR - TKI (p = 0.008 and p < 0.001, respectively). PRS was also significantly better in Wt than in Mt patients without EGFR - TKI (p < 0.001). The multivariate analysis identified the administration of EGFR - TKI as an independent prognostic factor for PRS (hazard ratio = 0.60; 95% confidence interval, 0.40-0.89). CONCLUSIONS: EGFR mutation tumors were associated with a significantly better RFS for recurrent pulmonary adenocarcinoma after curative resection of the lung, which represented the less aggressive nature of Mt tumors. However, patients with Mt did not have a favorable prognosis after recurrence unless they received EGFR TKI. PMID- 30290773 TI - Preoperative oral antibiotic prophylaxis reduces Pseudomonas aeruginosa surgical site infections after elective colorectal surgery: a multicenter prospective cohort study. AB - BACKGROUND: Healthcare-associated infections caused by Pseudomonas aeruginosa are associated with poor outcomes. However, the role of P. aeruginosa in surgical site infections after colorectal surgery has not been evaluated. The aim of this study was to determine the predictive factors and outcomes of surgical site infections caused by P. aeruginosa after colorectal surgery, with special emphasis on the role of preoperative oral antibiotic prophylaxis. METHODS: We conducted an observational, multicenter, prospective cohort study of all patients undergoing elective colorectal surgery at 10 Spanish hospitals (2011-2014). A logistic regression model was used to identify predictive factors for P. aeruginosa surgical site infections. RESULTS: Out of 3701 patients, 669 (18.1%) developed surgical site infections, and 62 (9.3%) of these were due to P. aeruginosa. The following factors were found to differentiate between P. aeruginosa surgical site infections and those caused by other microorganisms: American Society of Anesthesiologists' score III-IV (67.7% vs 45.5%, p = 0.001, odds ratio (OR) 2.5, 95% confidence interval (95% CI) 1.44-4.39), National Nosocomial Infections Surveillance risk index 1-2 (74.2% vs 44.2%, p < 0.001, OR 3.6, 95% CI 2.01-6.56), duration of surgery >=75thpercentile (61.3% vs 41.4%, p = 0.003, OR 2.2, 95% CI 1.31-3.83) and oral antibiotic prophylaxis (17.7% vs 33.6%, p = 0.01, OR 0.4, 95% CI 0.21-0.83). Patients with P. aeruginosa surgical site infections were administered antibiotic treatment for a longer duration (median 17 days [interquartile range (IQR) 10-24] vs 13d [IQR 8-20], p = 0.015, OR 1.1, 95% CI 1.00-1.12), had a higher treatment failure rate (30.6% vs 20.8%, p = 0.07, OR 1.7, 95% CI 0.96-2.99), and longer hospitalization (median 22 days [IQR 15-42] vs 19d [IQR 12-28], p = 0.02, OR 1.1, 95% CI 1.00-1.17) than those with surgical site infections due to other microorganisms. Independent predictive factors associated with P. aeruginosa surgical site infections were the National Nosocomial Infections Surveillance risk index 1-2 (OR 2.3, 95% CI 1.03-5.40) and the use of oral antibiotic prophylaxis (OR 0.4, 95% CI 0.23-0.90). CONCLUSIONS: We observed that surgical site infections due to P. aeruginosa are associated with a higher National Nosocomial Infections Surveillance risk index, poor outcomes, and lack of preoperative oral antibiotic prophylaxis. These findings can aid in establishing specific preventive measures and appropriate empirical antibiotic treatment. PMID- 30290775 TI - Risk factors for paclitaxel-induced peripheral neuropathy in patients with breast cancer. AB - BACKGROUND: Paclitaxel induced peripheral neuropathy (PIPN) is a major debilitating side effect of paclitaxel in patients with breast cancer with no fully known mechanisms. The aim of the study was to find out the possible risk factors for PIPN. METHODS: Eligible patients with node positive breast cancer undergoing chemotherapy with paclitaxel were assessed. They belonged to an initial randomized controlled trial in which the effectiveness of omega-3 fatty acids in preventing and reducing severity of PIPN was evaluated (protocol ID: NCT01049295). Reduced total neuropathy score (r-TNS) was used for measuring PIPN. All analyses were performed adjusting for intervention effect. The association between age, BMI, BSA, pathological grade, molecular biomarkers and PIPN was evaluated. RESULTS: Fifty-seven patients with breast cancer were investigated. Age was significantly associated with risk of PIPN (RR:1.50, P value = .024). Body mass index and BSA had significant association with severity of PIPN (B:1.28, P = .025; and B: 3.88, P = .010 respectively). Also, BSA showed a significant association with the risk of PIPN (RR: 2.28, P = .035; B: 3.88, P = .035). Incidence and severity of PIPN were much more pronounced in progesterone receptor positive (PR+) patients (RR:1.88, P = .015 and B:1.54, P = .012). Multivariate analysis showed that age and the status of PR+ were independent risk factor for incidence and the status of PR+ was the only independent risk factor for severity of PIPN. CONCLUSION: Age, BSA and the status of PR+, should be considered as the risk factors for PIPN before commencement of chemotherapy with paclitaxel in patients with breast cancer. Older patients, those with greater BSA and PR+ patients may need closer follow up and more medical attention due to greater incidence and severity of PIPN. PMID- 30290776 TI - An exploratory analysis of the interactions between social norms and the built environment on cycling for recreation and transport. AB - BACKGROUND: There is growing evidence of the public health benefits of promoting cycling. The ways that the built environment and perceived social norms independently influence cycling participation is well established. However, whether these factors interact to influence cycling participation has not been examined. Such research is important because understanding the effect of multiple socio-ecological factors and the interactions between them is needed to guide the development of interventions and strategies to increase cycling participation. Therefore, the aim of this study is to explore the interactive effects of the built environment and perceived social norms on transport and recreational cycling. METHODS: Data was collected using a self-administered online questionnaire from 228 office workers in Metropolitan Melbourne, Australia. Measures used in previous research were employed to assess self-reported transport and recreation cycling in the last week, perceptions of neighbourhood built environment, perceived social norms towards cycling, and objective land-use mix, residential density and street connectivity of the suburbs in which participants lived and work. Multiple binary logistic regression analyses were conducted to explore the interactive effects of the built environment and perceived social norms on transport and recreation cycling. All interactive effects were considered significant at p < 0.10. RESULTS: There was a significant interactive effect between the workplace built environment and perceived group norm on transport cycling (p = 0.06). There were no other significant interactive effects observed between components of the built environment and perceived social norms on transport or recreational cycling. CONCLUSIONS: The interactive effect found in this study provides some evidence that the workplace built environment interacts with perceived group norms to influence cycling for transport. Positive perceptions of the workplace built environment, such as showers and secure bike racks, can somewhat compensate for the negative influence of when cycling is considered less of a norm among, family, friend or colleagues. However, the findings of this study did not support that the neighbourhood built environment and perceived social norms interact to influence cycling for recreation or transport. These findings contribute to the knowledge of how multiple factors may reciprocate to influence individual's decision to cycle. More research into the interactive effects of socio-ecological factors is warranted. PMID- 30290778 TI - Long-term desensitization for ABO-incompatible living related kidney transplantation recipients with high refractory and rebound anti-blood type antibody: case report. AB - BACKGROUND: ABO-incompatible living related kidney transplantation (ABO-iLKT) has increased the possibilities for kidney transplantation in patients with end stage renal disease. Due to advancements in immunosuppressive agents and the identification of immunological conditions following ABO-iLKT, this transplantation technique has achieved the same success rate as ABO-compatible LKT. However, some patients continue to generate anti-blood type antibodies, despite conventional immunosuppressant treatment. CASE PRESENTATION: A 60-year old man was referred to our hospital for kidney transplantation. The proposed transplant was ABO incompatible, from a donor with blood-type A to a recipient with blood-type O. The recipient's anti-A blood-type IgG antibody titer was measured at 4096-fold dilution. Following desensitization therapy, including mycophenolate mofetil (MMF) 750 mg/day for 3 months, intravenous Rituximab 200 mg, and two sessions of double filtration plasmapheresis, the anti-A blood-type IgG antibody titer decreased to only 516-fold dilution and did not meet our target of less than 128-fold dilution. MMF was thus continued for an additional 4 months and four additional sessions of plasmapheresis were undertaken. Following these interventions, antibody titers decreased to 128-fold dilution and ABO-iLKT was performed. Following transplant, antibody-mediated rejection was not observed and renal function was preserved. However, a post-operative renal biopsy 1.5 months later showed evidence of T-cell-mediated rejection IB. The patient was treated with steroids, with no increase in serum creatinine. CONCLUSION: Our findings suggest that the long-term single MMF desensitization therapy could be a suitable option for ABO-iLKT with high refractory and rebound anti-blood type antibody. Further studies are required to establish the optimal immunosuppression regimen to control B cell- mediated immunity in ABO-iLKT. PMID- 30290779 TI - Conventional immunosuppressive therapy in severe Behcet's Uveitis: the switch rate to the biological agents. AB - BACKGROUND: To report the switch rate of conventional immunosuppressive (CIS) therapies to the biological agents (BA) in patients with refractory Behcet's uveitis (BU). METHODS: In this retrospective study, clinical records were reviewed of 76 patients' 116 eyes presenting with BU who had been treated with immunosuppressive drug therapy. Mann Whitney U test was used for the intergroup comparisons of parameters without normal distribution as well as calculation of descriptive statistical methods (mean, standard deviation, median, frequency and rate). Wilcoxon Signed Ranks test was used for the intragroup comparisons of parameters without normal distribution. Pearson's Chi-Square test and Fisher Freeman-Halton test were used for the comparisons of qualitative data. RESULTS: Except for one, all patients were first treated with CIS regimens for BU. Thirty one patients (41.3%) who were unresponsive to CIS regimens were switched to IFNalpha2a therapy. After that, eight of these cases were switched to the anti TNF-alpha treatments. The presence of initial ocular complications were found to be statistically higher in BA treated patients than the CIS treated cases (p < 0.001). Both in CIS treated and in BA treated cases, an increase in visual acuity (VA) was observed during the last examination compared to the initial examination and was significant (p < 0.001 and p = 0.018, respectively). CONCLUSIONS: CIS treatment was found to be effective and safe, as suggested in the management guidelines for severe BU. Biological therapy was also found effective for the improvement of the VA. We observed that 58.7% of cases could be treated with strong immunosuppressive therapies, however, nearly half of the patients could have lost their VA if BAs were not existent. During the treatment course of severe cases with BU, classical therapy stage must still be protected as the first-line therapy due to the their reasonable activity and safety. PMID- 30290777 TI - Development of a 3D, networked multi-user virtual reality environment for home therapy after stroke. AB - BACKGROUND: Impairment of upper extremity function is a common outcome following stroke, to the detriment of lifestyle and employment opportunities. Yet, access to treatment may be limited due to geographical and transportation constraints, especially for those living in rural areas. While stroke rates are higher in these areas, stroke survivors in these regions of the country have substantially less access to clinical therapy. Home therapy could offer an important alternative to clinical treatment, but the inherent isolation and the monotony of self-directed training can greatly reduce compliance. METHODS: We developed a 3D, networked multi-user Virtual Environment for Rehabilitative Gaming Exercises (VERGE) system for home therapy. Within this environment, stroke survivors can interact with therapists and/or fellow stroke survivors in the same virtual space even though they may be physically remote. Each user's own movement controls an avatar through kinematic measurements made with a low-cost, KinectTM device. The system was explicitly designed to train movements important to rehabilitation and to provide real-time feedback of performance to users and clinicians. To obtain user feedback about the system, 15 stroke survivors with chronic upper extremity hemiparesis participated in a multisession pilot evaluation study, consisting of a three-week intervention in a laboratory setting. For each week, the participant performed three one-hour training sessions with one of three modalities: 1) VERGE system, 2) an existing virtual reality environment based on Alice in Wonderland (AWVR), or 3) a home exercise program (HEP). RESULTS: Over 85% of the subjects found the VERGE system to be an effective means of promoting repetitive practice of arm movement. Arm displacement averaged 350 m for each VERGE training session. Arm displacement was not significantly less when using VERGE than when using AWVR or HEP. Participants were split on preference for VERGE, AWVR or HEP. Importantly, almost all subjects indicated a willingness to perform the training for at least 2-3 days per week at home. CONCLUSIONS: Multi-user VR environments hold promise for home therapy, although the importance of reducing complexity of operation for the user in the VR system must be emphasized. A modified version of the VERGE system is currently being used in a home therapy study. PMID- 30290781 TI - Mineral and bone disorder management in hemodialysis patients: comparing PTH control practices in Japan with Europe and North America: the Dialysis Outcomes and Practice Patterns Study (DOPPS). AB - BACKGROUND: High-circulating level of parathyroid hormone (PTH) is associated with elevated mortality in dialysis patients. The Japanese Society for Dialysis Therapy guideline suggests a lower PTH target than other international guidelines; thus, PTH control may differ in Japan compared with other regions, and be associated with mortality. METHODS: We analyzed data from hemodialysis patients with >=3 measurements of PTH during the first 9 months after enrollment in the Dialysis Outcomes and Practice Patterns Study (DOPPS) phases 4-5 (2009 2015). PTH control was assessed by the mean, slope, and mean squared error (MSE) of all PTH measurements over the 9-month run-in period. Distribution of each PTH control was assessed by regions (Europe/Australia/New Zealand [Eur/ANZ], Japan and North America) and dialysis vintage. Mortality rates were compared across PTH control categories using Cox regression models. RESULTS: Mean PTH was lower in Japan than in other regions across dialysis vintage categories. In patients with dialysis vintage < 90 days, PTH level was more likely to decline > 5% per month in Japan (48% of patients) versus Eur/ANZ (35%) and North America (35%). In patients with dialysis vintage > 1 year, Japanese patients maintained steady PTH, while patients in Eur/ANZ and North America were more likely to experience a PTH increase. Mean PTH was associated with mortality in the overall samples (highest mortality rate for PTH > 600 pg/mL, hazard ratio, 1.35; 95% confidence interval, 1.20 to 1.52 vs PTH 200-399 pg/mL), and the association was obvious in the prevalent patients (hazard ratio, 1.44; 95% confidence interval, 1.26 to 1.65). PTH slope and MSE did not show significant association with mortality in the overall sample as well as in subjects stratified both by region and dialysis vintage. CONCLUSION: PTH control in hemodialysis patients, as measured by keeping a stable PTH level over 9 months, was observed in Japan contrasted with other regions. High PTH mean, but not increased PTH slope and MSE, was associated with mortality especially in prevalent patients. PMID- 30290780 TI - Genome-wide association study identifies loci and candidate genes for non idiopathic pulmonary hypertension in Eastern Chinese Han population. AB - BACKGROUND: Pulmonary hypertension (PH) is a rare disease characterized by proliferation and occlusion of small pulmonary arterioles, which has been associated with a high mortality rate. The pathogenesis of PH is complex and incompletely understood, which includes both genetic and environmental factors that alter vascular structure and function. METHODS: Thus we aimed to reveal the potential genetic etiology of PH by targeting 143 tag SNPs of 14 candidate genes. Totally 208 individuals from Chinese Han population were enrolled in the present study, including 109 non-idiopathic PH patients and 99 healthy controls. RESULTS: The data revealed that 2 SNPs were associated with PH overall susceptibility at p < 3*10- 4 after Bonferroni correction. The top hit was rs6557421 (p = 4.5*10- 9), located within Nox3 gene on chromosome 6. Another SNP rs3744439 located in Tbx4 gene, also showed evidence of association with PH susceptibility (p = 1.2*10- 6). The distribution of genotype frequencies of rs6557421 and rs3744439 have dramatic differences between PH patients and controls. Individuals with rs6557421 TT genotype had a 10.72-fold/14.20-fold increased risk to develop PH when compared with GG or GG/GT carriers in codominant or recessive model, respectively (TT versus GG: 95%CI = 4.79-24.00; TT versus GG/GT: 95%CI = 6.65-30.33). As for rs3744439, AG genotype only occurred in healthy controls but has not been observed in PH patients. We further validated the result by using 26 different populations from five regions around the globe, including African (AFR), American (AMR), East Asian (EAS), European (EUR), and South Asian (SAS). In consistent with the present case-control study's results, significantly different genotype frequencies of the observed SNPs existed between PH patients and healthy individuals from all over the world. CONCLUSIONS: The results suggested that rs6557421 variant in Nox3 and rs3744439 variant in Tbx4 might have potential effect on individual susceptibility to pulmonary hypertension, which could lead to therapeutic or diagnosis approaches in PH. PMID- 30290782 TI - A qualitative study on the stigma experienced by people with mental health problems and epilepsy in the Philippines. AB - BACKGROUND: Stigma towards people with mental health problems (PMHP) is known to have substantial negative impacts on their lives. More in-depth exploration of the stigma and discrimination experienced by PMHP in low- and middle-income countries is needed. Previous research suggests that negative attitudes towards PMHP are widespread among the Filipino general public. However, no study has investigated PMHP's own experiences of being stigmatised in the Philippines. METHODS: A qualitative study was conducted on the stigma experienced by PMHP (including people with epilepsy) and its related factors in the Philippines, employing the constructivist grounded theory approach. We analysed data on 39 PMHP collected through interviews with PMHP, their carers, and community health volunteers who know them well. RESULTS: The findings highlight the culturally and socio-economically specific contexts, consequences, and impact modifiers of experiences of stigma. Participants emphasised that PMHP face stigma because of the cultural traits such as the perception of mental health problem as a disease of the family and the tendency to be overly optimistic about the severity of the mental health problem and its impact on their life. Further, stigma was experienced under conditions where mental health care was not readily available and people in the local community could not resolve the PMHP's mental health crisis. Stigma experiences reduced social networks and opportunities for PMHP, threatened the economic survival of their entire family, and exacerbated their mental health problems. An individual's reaction to negative experiences can be fatalistic in nature (e.g. believing in it is God's will). This fatalism can help PMHP to remain hopeful. In addition, traditional communal unity alleviated some of the social exclusion associated with stigma. CONCLUSIONS: The study indicates that existing stigma-reduction strategies might have limitations in their effectiveness across cultural settings. Therefore, we propose context-specific practical implications (e.g. emphasis on environmental factors as a cause of mental health problems, messages to increase understanding not only of the possibility of recovery but also of challenges PMHP face) for the Philippines. PMID- 30290783 TI - Barriers to bowel scope (flexible sigmoidoscopy) screening: a comparison of non responders, active decliners and non-attenders. AB - BACKGROUND: Participation in bowel scope screening (BSS) is low (43%), limiting its potential to reduce colorectal cancer (CRC) incidence and mortality. This study aimed to quantify the prevalence of barriers to BSS and examine the extent to which these barriers differed according to non-participant profiles: non responders to the BSS invitation, active decliners of the invitation, and non attenders of confirmed appointments. METHODS: Individuals invited for BSS between March 2013 and December 2015, across 28 General Practices in England, were sent a questionnaire. Questions measured initial interest in BSS, engagement with the information booklet, BSS participation, and, where applicable, reasons for BSS non-attendance. Chi-square tests of independence were performed to examine the relationship between barriers, non-participant groups and socio-demographic variables. RESULTS: 1478 (45.8%) questionnaires were returned for analysis: 1230 (83.2%) attended screening, 114 (7.7%) were non-responders to the BSS invitation, 100 (6.8%) were active decliners, and 34 (2.3%) were non-attenders. Non responders were less likely to have read the whole information booklet than active decliners (x2 (2, N = 157) = 7.00, p = 0.008) and non-attenders (x2 (2, N = 101) = 8.07, p = 0.005). Non-responders also had lower initial interest in having BSS than either active decliners (x2 (2, N = 213) = 6.07, p = 0.014) or non-attenders (x2 (2, N = 146) = 32.93, p < 0.001). Overall, anticipated pain (33%) and embarrassment (30%) were the most commonly cited barriers to BSS participation. For non-attenders, however, practical, appointment-related reasons were most common (27%). CONCLUSIONS: Interventions to improve BSS uptake should be more nuanced and use targeted strategies to address the specific needs of each group. PMID- 30290784 TI - Hydrogel coils versus bare platinum coils for the endovascular treatment of intracranial aneurysms: a meta-analysis of randomized controlled trials. AB - BACKGROUND: Recent studies have shown conflicting results regarding the effect of hydrogel coils for treating intracranial aneurysm compared to bare platinum coils. We implemented a meta-analysis to assess the value of hydrogel coils in intracranial aneurysm treatment. METHODS: The MEDLINE, EMBASE, and Cochrane Library databases were searched for randomized controlled trials (RCTs) which had evaluated hydrogel coils versus bare platinum coils for intracranial aneurysms. RESULTS: We pooled 1526 patients from 4 RCTs with the mean follow-up time of more than 16 months. Hydrogel coils had reductions on mid-term recurrence (RR 0.78, 95% CI 0.65 to 0.94, P = 0.008) and residual aneurysm (RR 0.71, 95% CI 0.57 to 0.88, P = 0.002), but didn't show any significant differences in other favorable outcomes such as functional recovery, mortality and so on. In the subgroup analysis, we found that second-generation hydrogel coils might exhibit potential impacts on increasing mid-term complete occlusion (RR 1.26, 95% CI 1.07 to 1.48, P = 0.005) and decreasing residual aneurysm neck. (RR 0.54, 95% CI 0.34 to 0.86, P = 0.010). CONCLUSIONS: Hydrogel coils showed no significant efficacy on functional recovery but exhibited a lower rate of recurrences and residual aneurysms in patients with intracranial aneurysms. PMID- 30290785 TI - "I'm used to doing it by myself": exploring self-reliance in pregnancy. AB - BACKGROUND: Self-reliance (the need to rely on one's own efforts and abilities) is cited as a potential coping strategy for decreased or absent social support during pregnancy. Little data exists on how women view self-reliance in pregnancy. METHODS: We recruited women from urban, walk-in pregnancy testing clinics from June 2014-June 2015. Women aged 16 to 44 and at less than 24 weeks gestational age were eligible. Participants completed an enrollment survey and in person, semi-structured interviews. We used framework analysis to identify key concepts and assess thematic relationships. RESULTS: Eighty-four English-speaking women completed qualitative interviews. Participants averaged 26 years of age and 7 weeks estimated gestational age. Most identified as Black (54%) or Hispanic (20%), were unemployed or homemakers (52%), unmarried (92%), and had at least one child (67%). Most did not intend to get pregnant (61%) and planned to continue their pregnancy and parent (65%). We identified self-reliance as a prevalent concept that almost half (48%) of participants discussed in relationship to their pregnancy. Self-reliance in pregnancy consisted of several subthemes: 1) past experiences, 2) expectations of motherhood, 3) financial independence, 4) decision making, and 5) parenting. CONCLUSIONS: Self-reliance is an important aspect of women's reproductive lives and is threaded through women's past and current thoughts, feelings, experiences and decisions about pregnancy. Women's belief in their own self-reliance as well as a recognition of the limits of self reliance merits further research, especially as a potential strategy to cope with decreased or absent social support during pregnancy. PMID- 30290786 TI - Oral mucositis associated with anti-EGFR therapy in colorectal cancer: single institutional retrospective cohort study. AB - BACKGROUND: Chemotherapy-induced oral mucositis impairs the quality of life. The difference in severity of oral mucositis between different anti-epidermal growth factor receptor (EGFR) antibodies combined with cytotoxic drugs in colorectal cancer is unclear. The aim of this study was to investigate the differences in oral mucositis between panitumumab (Pmab) and cetuximab (Cmab) combined with 5 fluorouracil (5-FU). METHODS: We conducted a retrospective cohort study. A total of 75 colorectal cancer outpatients treated with an anti-EGFR antibody combined with FOLFOX, FOLFIRI, or 5-FU/leucovorin as the first- to third-line treatment were included. The primary endpoint was the incidence of grade 2-3 oral mucositis. The secondary endpoint was the time to onset of oral mucositis. We also compared the incidence of toxicities of interest, skin toxicity, hypomagnesaemia and neutropenia, and time to treatment failure (TTF) between the two groups. RESULTS: Thirty-two patients treated with Pmab and 43 patients treated with Cmab were evaluated. Patient characteristics were similar between the two groups. The incidence of grade 2-3 oral mucositis was significantly higher with Pmab than with Cmab (31.3% vs 9.3%, P < 0.05). Moreover, the incidence of grade 3 oral mucositis was significantly higher in patients treated with Pmab (18.8% vs 0%, P < 0.01). The mean (SD) cycles to onset of the worst oral mucositis was 3.0 (2.9) in the Pmab group and 2.3 (1.7) in the Cmab group (P = 0.29). Oral mucositis was characterized by glossitis and cheilitis. The incidences of other toxicities were the following (Pmab vs Cmab): grade 2-3 skin toxicity: 68.8% vs 74.4% (P = 0.61), grade 2-3 hypomagnesaemia: 9.3% vs 7.0% (P = 1.00), grade 3-4 neutropenia: 28.1% vs 37.2% (P = 0.46). The median TTF was not significantly different, i.e., 223 days vs 200 days (P = 0.39) for Pmab vs Cmab. CONCLUSIONS: Pmab-based chemotherapy resulted in significantly higher grades of oral mucositis compared with Cmab-based chemotherapy. The oral condition should be monitored carefully and early supportive care should be provided for patients treated with Pmab-based chemotherapy. PMID- 30290787 TI - Association between acromegaly and a single nucleotide polymorphism (rs2854744) in the IGFBP3 gene. AB - BACKGROUND: It has been reported that the single nucleotide polymorphism (SNP) rs2854744 at the - 202 locus of insulin-like growth factor binding protein-3 (IGFBP3) is associated with serum levels and a number of malignancies. However, the effect of IGFBP3 gene polymorphism on acromegaly is less clear. Therefore, in the current study, we aimed to investigate whether the -202A/C polymorphism of IGFBP3 constitutes a risk factor for acromegaly. METHODS: The study included 102 acromegalic patients and 143 control subjects in Beijing Tiantan Hospital. The genotyping of IGFBP3 was carried out using the MassARRAY method. Serum IGFBP3 concentrations were also determined. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the associations of genetic polymorphisms with the development of acromegaly and its different subtypes. RESULTS: The study revealed that the C allele of rs2854744 was associated with a reduced risk of acromegaly (OR 0.594, 95% CI 0.388-0.909), as well as with the female (OR 0.385, 95% CI 0.206-0.72), macroadenoma (OR 0.557, 95% CI 0.347-0.893) and monotherapy (OR 0.512, 95% CI 0.316-0.828) subgroups under the additive model. A higher serum IGFBP3 level was observed in patients with the AA genotype, but this difference was not significant (P = 0.331). CONCLUSION: This study is one of the first to show that the IGFBP3 polymorphism may have an influence on serum levels and that the C allele of rs2854744 is associated with a reduced risk of acromegaly. This correlation was more prominent in females, those with large tumours and those treated with monotherapy in a Chinese population. Genetic polymorphism of IGFBP3 may be involved in the development of acromegaly. PMID- 30290788 TI - Study of the reasons for the consumption of each type of vegetable within a population of school-aged children. AB - BACKGROUND: Several studies have evaluated the existence of factors that influence the consumption of vegetables in children, such as family environment, daily exposure to one or several vegetables, parents' consumption and consumption pattern and the way in which vegetables are prepared in the household, among others. The objective of this study was to investigate the reasons for consumption associated with each vegetable in school-aged children through a survey designed to be answered by the parents. METHODS: A preliminary study with 162 parents was carried out on the consumption of vegetables in children aged 6 to 12 years. Based on the information obtained, a survey was designed with 14 phrases to investigate the reasons for the low consumption of each type of vegetable among school-aged children, which was answered online by 419 parents. RESULTS: The results obtained allowed us to categorise the vegetables into 6 groups. Group A consisted of tomatoes, corn, pumpkin and carrots as the vegetables that children like to eat most. Group B contains the vegetables that are consumed mostly camouflaged in other preparations, such as onions and red peppers. Group C contains only cauliflower, which was negatively associated with senses, such as colour, smell and taste. This vegetable was never offered to children by a high percentage of parents. Group D consists of green vegetables: zucchini, spinach, chard and peas. Vegetables of this group are added to other foods and the child usually ingests them camouflaged or obliged. Group E consists of beetroot, lettuce and broccoli. Beetroot and lettuce were the vegetables parents reported were most often rejected by their children. This rejection, they stated, was due to sensory aspects, such as colour, texture and taste. CONCLUSIONS: The reasons for consumption among school-aged children depend on each type of vegetable and cannot be generalized. The sensory characteristics of the vegetable (mainly colour and flavour) and the habits of consumption in the family environment play a major role in children's acceptance or rejection of vegetables. PMID- 30290789 TI - Salivary cortisol in post-traumatic stress disorder: a systematic review and meta analysis. AB - BACKGROUND: Studies investigating salivary cortisol level as susceptibility marker for post-traumatic stress disorder (PTSD) produced inconsistent results. The aim of this study was to compare salivary cortisol concentration levels in PTSD patients with those in controls by synthesizing published data. METHODS: We did a systematic review, meta-analysis and meta-regression of studies comparing concentrations of salivary cortisol between patients with PTSD and controls. The electronic databases of PubMed, Embase, Web of Science and Psyc-ARTICLES were searched for relevant articles. A random-effects model with restricted maximum likelihood estimator is used to synthesize the effect size (assessed by standardized mean difference). RESULTS: A total of 784 articles were identified of which 22 were included in the final analysis. A trend of lower salivary cortisol levels was found in PTSD patients when compared with the controls (SMD = - 0.28, 95% CI-0.53;-0.04, p = 0.022). Subgroup analysis showed that the salivary cortisol levels were lower in patients with PTSD than in controls in studies conducted after 2007 or in studies using saliva samples collected in the morning. CONCLUSIONS: The evidence from this meta-analysis supports that salivary samples collected in the morning consistently showed a lower salivary cortisol level in patients with PTSD than in controls, although whether salivary cortisol could be used as a diagnostic tool requires further research. PMID- 30290790 TI - An enhanced regimen as post-exposure chemoprophylaxis for leprosy: PEP+. AB - The ongoing transmission of Mycobacterium (M.) leprae reflected in a very slow decline in leprosy incidence, forces us to be innovative and conduct cutting-edge research. Single dose rifampicin (SDR) as post-exposure prophylaxis (PEP) for contacts of leprosy patients, reduces their risk to develop leprosy by 60%. This is a promising new preventive measure that can be integrated into routine leprosy control programmes, as is being demonstrated in the Leprosy Post-Exposure Programme that is currently ongoing in eight countries.The limited (60%) effectiveness of SDR is likely due to the fact that some contacts have a preclinical infection beyond the early stages for which SDR is not sufficient to prevent the development of clinical signs and symptoms of leprosy. An enhanced regimen, more potent against a higher load of leprosy bacteria, would increase the effectiveness of this preventive measure significantly.The Netherlands Leprosy Relief (NLR) is developing a multi-country study aiming to show that breaking the chain of transmission of M. leprae is possible, evidenced by a dramatic reduction in incidence. In this study the assessment of the effectiveness of an enhanced prophylactic regimen for leprosy is an important component. To define the so called PEP++ regimen for this intervention study, NLR convened an Expert Meeting that was attended by clinical leprologists, public health experts, pharmacologists, dermatologists and microbiologists.The Expert Meeting advised on combinations of available drugs, with known efficacy against leprosy, as well as on the duration of the intake, aiming at a risk reduction of 80-90%. To come to a conclusion the Expert Meeting considered the bactericidal, sterilising and bacteriostatic activity of the potential drugs. The criteria used to determine an optimal enhanced regimen were: effectiveness, safety, acceptability, availability, affordability, feasibility and not inducing drug resistance.The Expert Meeting concluded that the enhanced regimen for the PEP++ study should comprise three standard doses of rifampicin 600 mg (weight adjusted when given to children) plus moxifloxacin 400 mg given at four-weekly intervals. For children and for adults with contraindications for moxifloxacin, moxifloxacin should be replaced by clarithromycin 300 mg (weight adjusted). PMID- 30290791 TI - The palatine tonsil bacteriome, but not the mycobiome, is altered in HIV infection. AB - BACKGROUND: Microbial flora in several organs of HIV-infected individuals have been characterized; however, the palatine tonsil bacteriome and mycobiome and their relationship with each other remain unclear. Determining the palatine tonsil microbiome may provide a better understanding of the pathogenesis of oral and systemic complications in HIV-infected individuals. We conducted a cross sectional study to characterize the palatine tonsil microbiome in HIV-infected individuals. RESULTS: Palatine tonsillar swabs were collected from 46 HIV infected and 20 HIV-uninfected individuals. The bacteriome and mycobiome were analyzed by amplicon sequencing using Illumina MiSeq. The palatine tonsil bacteriome of the HIV-infected individuals differed from that of HIV-uninfected individuals in terms of the decreased relative abundances of the commensal genera Neisseria and Haemophilus. At the species level, the relative abundances and presence of Capnocytophaga ochracea, Neisseria cinerea, and Selenomonas noxia were higher in the HIV-infected group than those in the HIV-uninfected group. In contrast, fungal diversity and composition did not differ significantly between the two groups. Microbial intercorrelation analysis revealed that Candida and Neisseria were negatively correlated with each other in the HIV-infected group. HIV immune status did not influence the palatine tonsil microbiome in the HIV infected individuals. CONCLUSIONS: HIV-infected individuals exhibit dysbiotic changes in their palatine tonsil bacteriome, independent of immunological status. PMID- 30290792 TI - Transcriptional profiling of embryos lacking the lipoprotein receptor SR-B1 reveals a regulatory circuit governing a neurodevelopmental or metabolic decision during neural tube closure. AB - BACKGROUND: The high-density lipoprotein receptor SR-B1 mediates cellular uptake of several lipid species, including cholesterol and vitamin E. During early mouse development, SR-B1 is located in the maternal-fetal interface, where it facilitates vitamin E transport towards the embryo. Consequently, mouse embryos lacking SR-B1 are vitamin E-deficient, and around half of them fail to close the neural tube and show cephalic neural tube defects (NTD). Here, we used transcriptomic profiling to identify the molecular determinants of this phenotypic difference between SR-B1 deficient embryos with normal morphology or with NTD. RESULTS: We used RNA-Seq to compare the transcriptomic profile of three groups of embryos retrieved from SR-B1 heterozygous intercrosses: wild-type E9.5 embryos (WT), embryos lacking SR-B1 that are morphologically normal, without NTD (KO-N) and SR-B1 deficient embryos with this defect (KO-NTD). We identified over 1000 differentially expressed genes: down-regulated genes in KO-NTD embryos were enriched for functions associated to neural development, while up-regulated genes in KO-NTD embryos were enriched for functions related to lipid metabolism. Feeding pregnant dams a vitamin E-enriched diet, which prevents NTD in SR-B1 KO embryos, resulted in mRNA levels for those differentially expressed genes that were more similar to KO-N than to KO-NTD embryos. We used gene regulatory network analysis to identify putative transcriptional regulators driving the different embryonic expression profiles, and identified a regulatory circuit controlled by the androgen receptor that may contribute to this dichotomous expression profile in SR-B1 embryos. Supporting this possibility, the expression level of the androgen receptor correlated strongly with the expression of several genes involved in neural development and lipid metabolism. CONCLUSIONS: Our analysis shows that normal and defective embryos lacking SR-B1 have divergent expression profiles, explained by a defined set of transcription factors that may explain their divergent phenotype. We propose that distinct expression profiles may be relevant during early development to support embryonic nutrition and neural tube closure. PMID- 30290794 TI - Determination of ED50 and time to effectiveness for intrathecal hydromorphone in laboring patients using Dixon's up-and-down sequential allocation method. AB - BACKGROUND: With the increasing occurrence of drug shortages, understanding the pharmacokinetics of alternative intrathecal opioid administration has gained importance. In particular, additional data are needed to comprehensively evaluate the analgesic properties of intrathecal hydromorphone in the laboring patient. In a phase 2 clinical trial, we set out to determine the median effective dose (ED50) and time to effectiveness for this drug in this population. METHODS: Using Dixon's up-and-down sequential allocation method, twenty women presenting for labor analgesia were prospectively enrolled. A combined spinal-epidural technique was used to deliver the determined dose of intrathecal hydromorphone. Visual analog pain scores were obtained assessing peak pain scores during serial uterine contractions. Effective pain relief was defined as achieving a pain score of less than or equal to 3 out of 10. The dose was deemed to be ineffective if the patient failed to achieve this level of relief after 30 min. RESULTS: The ED50 of hydromorphone in our population was 10.9 MUg (95% confidence interval 5.6-16.2 MUg). Amongst patients for whom the dose was effective, the median time to pain relief was 24 min. One patient experienced both nausea and pruritus. No other complications were noted. CONCLUSION: Due to the prolonged time to onset, hydromorphone cannot be recommended in favor of substantively better alternatives such as sufentanil and fentanyl. TRIAL REGISTRATION: Clinicaltrials.gov registration number: NCT01598506. PMID- 30290793 TI - Integrated motivational interviewing and cognitive behaviour therapy for lifestyle mediators of overweight and obesity in community-dwelling adults: a systematic review and meta-analyses. AB - BACKGROUND: The aim of this study was to investigate whether integrated motivational interviewing and cognitive behaviour therapy leads to changes in lifestyle mediators of overweight and obesity in community-dwelling adults. METHOD: Six electronic databases were systematically searched up to 04 October, 2017. Analyses were restricted to randomised controlled trials that examined the effect of integrated motivational interviewing and cognitive behaviour therapy on lifestyle mediators of overweight and obesity (physical activity, diet, body composition) in community-dwelling adults. Meta-analyses were conducted using change scores from baseline in outcome measures specific to the lifestyle mediators of overweight and obesity to determine standardized mean differences (SMD) and 95% confidence intervals (95% CI). The Grades of Recommendation, Assessment, Development and Evaluation approach was used to evaluate the quality of the evidence. RESULTS: Ten randomised controlled trials involving 1949 participants were included. Results revealed moderate quality evidence that integrated motivational interviewing and cognitive behaviour therapy had a significant effect in increasing physical activity levels in community-dwelling adults (SMD: 0.18, 95% CI: 0.06 to 0.31, p < 0.05). The combined intervention resulted in a small, non-significant effect in body composition changes (SMD: 0.12, 95% CI: -0.24 to 0.01, p = 0.07). Insufficient evidence existed for outcome measures relating to dietary change. DISCUSSION: The addition of integrated motivational interviewing and cognitive behaviour therapy to usual care can lead to modest improvements in physical activity and body composition for community dwelling adults. The available evidence demonstrates that it is feasible to integrate MI with CBT and that this combined intervention has the potential to improve health-related outcomes. CONCLUSION: This review details recommendations for future research including the adoption of uniform objective outcome measures and well-defined interventions with sufficient follow-up durations and assessments of treatment fidelity.

AB - BACKGROUND: Cecropin A (CeA), a natural cationic antimicrobial peptide, exerts potent antimicrobial activity against a broad spectrum of Gram-positive and Gram negative bacteria, making it an attractive candidate substitute for antimicrobials. However, the low production rate and cumbersome, expensive processes required for both its recombinant and chemical synthesis have seriously hindered the exploitation and application of CeA. Here, we utilized a short beta structured self-aggregating protein, ELK16, as a fusion partner of CeA, which allowed the efficient production of high-purity CeA antibacterial peptide with a simple inexpensive process. RESULTS: In this study, three different approaches to the production of CeA peptide were investigated: an affinity tag (His-tag)-fused protein expression system (AT-HIS system), a cell-free protein expression system (CF system), and a self-assembling peptide (ELK16)-fused protein expression system (SA-ELK16 system). In the AT-HIS and CF systems, the CeA peptide was obtained with purities of 92.1% and 90.4%, respectively, using one or more affinity-chromatographic purification steps. The procedures were tedious and costly, with CeA yields of only 0.41 and 0.93 MUg/mg wet cell weight, respectively. Surprisingly, in the SA-ELK16 system, about 6.2 MUg/mg wet cell weight of high-purity (approximately 99.8%) CeA peptide was obtained with a simple low-cost process including steps such as centrifugation and acetic acid treatment. An antimicrobial test showed that the high-purity CeA produced in this study had the same antimicrobial activity as synthetic CeA peptide. CONCLUSIONS: In this study, we designed a suitable expression system (SA-ELK16 system) for the production of the antibacterial peptide CeA and compared it with two other protein expression systems. A high yield of high-purity CeA peptide was obtained with the SA-ELK16 system, which greatly reduced the cost and time required for downstream processing. This system may provide a platform for the laboratory scale production of the CeA antibacterial peptide. PMID- 30290796 TI - Factors associated with anaemia in kidney transplant recipients in the first year after transplantation: a cross-sectional study. AB - BACKGROUND: Anaemia after kidney transplantation may reduce quality of life, graft or patient survival. We aimed to determine the prevalence and risk factors for anaemia in the initial 12 months after transplantation. METHODS: We conducted a cross-sectional study at 6 and 12 months after transplantation. Anaemia was defined by World Health Organization criteria taking into consideration erythropoietin use. Logistic regression was used to determine the association between demographic, clinical and pharmacological risk factors for the main outcome of moderate-severe anaemia. RESULTS: A total of 336 transplant recipients were included and the prevalence of moderate-severe anaemia was 27.4% at 6 months and 15.2% at 12 months. Lower kidney function, female gender, transferrin saturation below 10% and proteinuria were associated with moderate-severe anaemia at both time points. Recent intravenous immunoglobulin treatment was associated with anaemia at 6 months. Recent infection and acute rejection were also associated with anaemia 12 months. Around 20% of patients had at least one blood transfusion but they were uncommon beyond 3 months. CONCLUSIONS: Anaemia remains highly prevalent requiring treatment with erythropoietin and transfusions. Most identifiable risk factors relate to clinical problems rather than pharmacological management, while markers of iron-deficiency remain difficult to interpret in this setting. PMID- 30290797 TI - Reliability, ease of use and usefulness of I-MeDeSA for evaluating drug-drug interaction alerts in an Australian context. AB - BACKGROUND: Recently, attention has shifted to improving the design of computerized alerts via the incorporation of human factors design principles. The Instrument for Evaluating Human Factors Principles in Medication-Related Decision Support Alerts (I-MeDeSA) is a tool developed in the United States to guide improvements to alert design and facilitate selection of electronic systems with superior design. In this study, we aimed to determine the reliability, ease of use and usefulness of I-MeDeSA for assessing drug-drug interaction (DDI) alerts in an Australian context. METHODS: Using the I-MeDeSA, three reviewers independently evaluated DDI alert interfaces of seven electronic systems used in Australia. Inter-rater reliability was assessed and reviewers met to discuss difficulties in using I-MeDeSA and the tool's usefulness. RESULTS: Inter-rater reliability was high (Krippendorff's alpha = 0.76), however, ambiguous wording and the inclusion of conditional items impacted ease of use. A number of items were not relevant to Australian implementations and as a result, most systems achieved an I-MeDeSA score of less than 50%. CONCLUSIONS: The I-MeDeSA proved to be reliable, but item wording and structure made application difficult. Future studies should investigate potential modifications to the I-MeDeSA to improve ease of use and increase applicability to a variety of system configurations. PMID- 30290798 TI - Caesarean section rate and postnatal bed occupancy: a retrospective study replacing assumptions with evidence. AB - BACKGROUND: Obstetric units across the UK face resource pressures alongside a rising rate of Caesarean section (CS). It is assumed that this places a further burden in the form of postnatal bed demands. The number of inpatient beds has fallen nationally, and this may be used to justify attempts to restrict the CS rate. We set out to replace such assumptions with evidence. We did not find any similar contemporary analysis in a literature search. METHODS: The postnatal length of stay (LOS) of women delivering at Watford General Hospital, a large unit hosting around 5500 deliveries per annum, was stratified by mode of delivery. Differences within and across time periods were analysed. RESULTS: The CS rate rose from 14.5% in 1995 to 30.9% in 2015. The mean LOS post-CS declined from 4.2 to 2.4 days. These data were statistically significant to p < 0.001. Over this period the standardised total postnatal bed use for all delivery modes fell from 11083 days to 7894 days. A 113% rise in the CS rate was accommodated by only a 19.8% rise in postnatal bed use attributable to CS patients. CONCLUSIONS: Whatever pressures may be exacerbated by the rising CS rate, bed occupancy is not one of them. In discussion we widen our argument to suggest that resource pressures should not be used to justify limitations in the CS rate. PMID- 30290799 TI - Shady business: understanding the spatial ecology of exophilic Anopheles mosquitoes. AB - BACKGROUND: Understanding the ecology of exophilic anophelines is a key step toward developing outdoor control strategies to complement existing indoor control tools against malaria vectors. This study was conducted to assess the movement pattern of exophilic Anopheles mosquitoes between blood meal sources and resting habitats, and the landscape factors dictating their resting habitat choice. RESULTS: Resting clay pots were placed at 5 m, 25 m, 50 m, 75 m and 100 m away from isolated focal houses, radiating from them in four directions. The locations of the clay pots represent heterogeneous land cover types at a relatively fine spatial scale in the landscape. The effect of the landscape characters on the number of both female and male anophelines caught was modelled using zero-inflated negative binomial regression with a log link function. A total of 420 Anopheles mosquitoes (353 females and 67 males) belonging to three species; Anopheles arabiensis, Anopheles pharoensis, and Anopheles tenebrosus were caught in the resting clay pots, with An. arabiensis being the dominant species. Canopy cover, distance from the house, and land cover type were the significant landscape characters influencing the aggregation of resting mosquitoes. Both the count and binary models showed that canopy cover was the strongest predictor variable on the counts and the presence of Anopheles mosquitoes in the clay pots. Female Anopheles were most frequently found resting in the pots placed in banana plantations, and at sampling points that were at the greater distances (75 m and 100 m) from the focal house. CONCLUSIONS: This study showed that exophilic Anopheles mosquitoes tend to rest in shaded areas some distance away from human habitation. These findings are important when targeting mosquitoes outdoors, complementing the existing effort being made to control malaria vectors indoors. PMID- 30290800 TI - Comparative cardio and developmental toxicity induced by the popular medicinal extract of Sutherlandia frutescens (L.) R.Br. detected using a zebrafish Tuebingen embryo model. AB - BACKGROUND: Sutherlandia frutescens is one of the most promising commercialized, indigenous and medicinal plants of South Africa that is used as an immune booster, and a traditional treatment for cancer. However, few studies report on its toxicology and dosage in vivo. There is still room to better understand its cytotoxicity effects in animal systems. METHODS: We prepared two extracts, one with 80% (v/v) ethanol, and the other, with water. Both were studied to determine the maximum tolerable concentration when extracts were applied at 0 to 200 MUg/ml to a Tuebingen zebrafish embryo line. The development of zebrafish embryos after 24 h post fertilization (hpf) was studied. A concentration range of 5 MUg/ml to 50 MUg/ml was then chosen to monitor the ontological development of cultured embryos. A liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) method was used to study the differences of the two experimental extracts. Chemical variation between the extracts was illustrated using chemometrics. RESULTS: Both extracts led to bleeding and pericardial cyst formation when applied at high concentrations to the zebrafish embryo culture. Chronic teratogenic toxicities, leading to pericardial edema, yolk sac swelling, and other abnormal developmental characteristics, were detected. The aqueous extracts of S. frutescens were less toxic to the larvae than the ethanol extracts, validating preference for aqueous preparations when used in traditional medicine. Chemical differences between the water extracts and alcoholic extracts were analysed using LC-MS/MS. A supervised metabolomics approach, targeting the sutherlandiosides and sutherlandins using orthogonal partial least squares discriminant analysis (OPLS-DA), illustrated that sutherlandiosides were the main chemical features that can be used to distinguish between the two extracts, despite the extracts being highly similar in their chemical constituents. CONCLUSION: The water extract caused less cytotoxic and abnormal developmental effects compared to the ethanolic extract, and, this is likely due to differences in concentrations of extracted chemicals rather than the chemical profile per se. This study provides more evidence of cytotoxicity effects linked to S. frutescens using the zebrafish embryo bioassay as a study tool. PMID- 30290801 TI - Concomitant inhaled corticosteroid use and the risk of pneumonia in COPD: a matched-subgroup post hoc analysis of the UPLIFT(r) trial. AB - BACKGROUND: Use of inhaled corticosteroids (ICS) increases the risk of pneumonia in chronic obstructive pulmonary disease (COPD), but the magnitude of risk with different ICS remains unclear. METHODS: A post hoc analysis of the 4-year UPLIFT(r) trial to assess whether pneumonia risk differed by type of ICS (fluticasone propionate [FP], other ICS, or no ICS) in permanent users (defined by use until end of study) or in users at baseline (sensitivity analysis). RESULTS: For the permanent-users analysis, 825 patients receiving FP throughout the trial, 825 patients receiving other ICS and 825 patients not receiving ICS were matched on relevant baseline features 1:1:1. A significantly greater risk of pneumonia was observed for FP versus no ICS: the hazard ratio (HR) for risk of pneumonia was 1.33 (95% confidence interval [CI] 1.00, 1.75; p = 0.046) and the rate ratio (RR) was 1.58 (95% CI 1.05, 2.37; p = 0.028). A greater risk was also found for FP versus other ICS: HR 1.28 (95% CI 0.97, 1.68; p = 0.078) and RR 1.48 (95% CI 1.00, 2.19; p = 0.049). A higher proportion of patients on FP were hospitalized with pneumonia (7.9%) versus other ICS (6.7%) or no ICS (5.9%). Whilst other ICS use was associated with the highest number of fatal pneumonia events, the total number of fatal pneumonia incidents was low. A similar pattern was observed in the sensitivity analyses, which included 4002 patients on different treatments at baseline (FP, other ICS, and no ICS) and considered potential switches during the study. CONCLUSION: The results support existing evidence of an increased pneumonia risk with FP use compared with other ICS and no ICS use in patients with COPD. Healthcare professionals should evaluate the risk-benefit ratio of using ICS when making treatment decisions with their patients. TRIAL REGISTRATION: Post hoc analysis of UPLIFT(r). ClinicalTrials.gov number: NCT00144339 . Retrospectively registered September 2, 2005. PMID- 30290802 TI - An odorant receptor from Anopheles sinensis in China is sensitive to oviposition attractants. AB - BACKGROUND: Anopheles sinensis is an important vector for the spread of malaria in China. Olfactory-related behaviours, particularly oviposition site seeking, offer opportunities for disrupting the disease-transmission process. RESULTS: This is the first report of the identification and characterization of AsinOrco and AsinOR10 in An. sinensis. AsinOrco and AsinOR10 share 97.49% and 90.37% amino acid sequence identity, respectively, with related sequences in Anopheles gambiae. A functional analysis demonstrated that AsinOrco- and AsinOR10 coexpressing HEK293 cells were highly sensitive to 3-methylindole, but showed no significant differences in response to other test odorants when compared to DMSO. CONCLUSIONS: AsinOrco was characterized as a new member of the Orco ortholog subfamily. AsinOR10, which appears to be a member of the OR2-10 subfamily, is directly involved in identification of oviposition sites. This finding will help to elucidate the molecular mechanisms underlying olfactory signaling in An. sinensis and provide many more molecular targets for eco-friendly pest control. PMID- 30290803 TI - The randomised uterine septum transsection trial (TRUST): design and protocol. AB - BACKGROUND: A septate uterus is a uterine anomaly that may affect reproductive outcome, and is associated with an increased risk for miscarriage, subfertility and preterm birth. Resection of the septum is subject of debate. There is no convincing evidence concerning its effectiveness and safety. This study aims to assess whether hysteroscopic septum resection improves reproductive outcome in women with a septate uterus. METHODS/DESIGN: A multi-centre randomised controlled trial comparing hysteroscopic septum resection and expectant management in women with recurrent miscarriage or subfertility and diagnosed with a septate uterus. The primary outcome is live birth, defined as the birth of a living foetus beyond 24 weeks of gestational age. Secondary outcomes are ongoing pregnancy, clinical pregnancy, miscarriage and complications following hysteroscopic septum resection. The analysis will be performed according to the intention to treat principle. Kaplan-Meier curves will be constructed, estimating the cumulative probability of conception leading to live birth rate over time. Based on retrospective studies, we anticipate an improvement of the live birth rate from 35% without surgery to 70% with surgery. To demonstrate this difference, 68 women need to be randomised. DISCUSSION: Hysteroscopic septum resection is worldwide considered as a standard procedure in women with a septate uterus. Solid evidence for this recommendation is lacking and data from randomised trials is urgently needed. TRIAL REGISTRATION: Dutch trial registry ( NTR1676 , 18th of February 2009). PMID- 30290804 TI - Genetic diagnosis of neurofibromatosis type 1: targeted next- generation sequencing with Multiple Ligation-Dependent Probe Amplification analysis. AB - BACKGROUND: Neurofibromatosis type 1 (NF1) is a dominantly inherited tumor predisposition syndrome that targets the peripheral nervous system. It is caused by mutations of the NF1 gene which serve as a negative regulator of the cellular Ras/MAPK (mitogen-activated protein kinases) signaling pathway. Owing to the complexity in some parts of clinical diagnoses and the need for better understanding of its molecular relationships, a genetic characterization of this disorder will be helpful in the clinical setting. METHODS: In this study, we present a customized targeted gene panel of NF1/KRAS/BRAF/p53 and SPRED1 genes combined with Multiple Ligation-Dependent Probe Amplification analysis for the NF1 mutation screening in a cohort of patients clinically suspected as NF1. RESULTS: In this study, we identified 73 NF1 mutations and two BRAF novel variants from 100 NF1 patients who were suspected as having NF1. These genetic alterations are heterogeneous and distribute in a complicated way without clustering in either cysteine-serine-rich domain or within the GAP-related domain. We also detected fifteen multi-exon deletions within the NF1 gene by MLPA Analysis. CONCLUSIONS: Our results suggested that a genetic screening using a NGS panel with high coverage of Ras-signaling components combined with Multiple Ligation-Dependent Probe Amplification analysis will enable differential diagnosis of patients with overlapping clinical features. PMID- 30290806 TI - Dissociating motor learning from recovery in exoskeleton training post-stroke. AB - BACKGROUND: A large number of robotic or gravity-supporting devices have been developed for rehabilitation of upper extremity post-stroke. Because these devices continuously monitor performance data during training, they could potentially help to develop predictive models of the effects of motor training on recovery. However, during training with such devices, patients must become adept at using the new "tool" of the exoskeleton, including learning the new forces and visuomotor transformations associated with the device. We thus hypothesized that the changes in performance during extensive training with a passive, gravity supporting, exoskeleton device (the Armeo Spring) will follow an initial fast phase, due to learning to use the device, and a slower phase that corresponds to reduction in overall arm impairment. Of interest was whether these fast and slow processes were related. METHODS: To test the two-process hypothesis, we used mixed-effect exponential models to identify putative fast and slow changes in smoothness of arm movements during 80 arm reaching tests performed during 20 days of exoskeleton training in 53 individuals with post-acute stroke. RESULTS: In line with our hypothesis, we found that double exponential models better fit the changes in smoothness of arm movements than single exponential models. In contrast, single exponential models better fit the data for a group of young healthy control subjects. In addition, in the stroke group, we showed that smoothness correlated with a measure of impairment (the upper extremity Fugl Meyer score - UEFM) at the end, but not at the beginning, of training. Furthermore, the improvement in movement smoothness due to the slow component, but not to the fast component, strongly correlated with the improvement in the UEFM between the beginning and end of training. There was no correlation between the change of peaks due to the fast process and the changes due to the slow process. Finally, the improvement in smoothness due to the slow, but not the fast, component correlated with the number of days since stroke at the onset of training - i.e. participants who started exoskeleton training sooner after stroke improved their smoothness more. CONCLUSIONS: Our results therefore demonstrate that at least two processes are involved in in performance improvements measured during mechanized training post-stroke. The fast process is consistent with learning to use the exoskeleton, while the slow process independently reflects the reduction in upper extremity impairment. PMID- 30290807 TI - Equity assessment of the distribution of CT and MRI scanners in China: a panel data analysis. AB - BACKGROUND: Distribution equity assessment of computed tomography (CT) and magnetic resonance imaging (MRI) scanners is an important dimension of access to health technology. However, limited studies on the subject have been done in China. This study aims to reveal the distribution status of CT and MRI scanners and assess their distribution equity of them in China. METHODS: Five provinces with 66 cities from China were selected as the study sites. Descriptive analysis was used for the absolute number and number per million population of CT and MRI scanners in the study sites. Fixed effect model was used to examine the health service factors that were associated with the allocation of CT and MRI scanners. The Gini coefficient and concentration index was used to evaluate the distribution equity of CT and MRI scanners. RESULTS: The absolute number and number per million population of CT and MRI scanners in five provinces were lower than those of Organization for Economic Co-operation and Development (OECD) countries, but annual growth rates were relatively higher from 2005 or 2006 to 2013. Population, GDP, number of hospitals, number of health professionals, number of hospital beds, number of outpatient visits, and number of inpatient visits all had a positive correlation with the allocation number of CT and MRI scanners. Moreover, the number of health professionals and the number of beds had a much closer correlation than other variables. All the Gini coefficients of CT and MRI had decreased overall. The concentration indices of CT and MRI were all positive and no more than 0.30. CONCLUSIONS: Large gaps in the number of CT and MRI scanners per million population between China and OECD countries emerge, although the growth rate is higher in China. The distribution equity of CT and MRI scanners in China was relatively good from 2005 or 2006 to 2013. The overall distribution equity of CT and MRI scanners also improved during the period. However, consideration attention should be given to the area with large economic disparities. PMID- 30290805 TI - Biotechnological applications of archaeal enzymes from extreme environments. AB - To date, many industrial processes are performed using chemical compounds, which are harmful to nature. An alternative to overcome this problem is biocatalysis, which uses whole cells or enzymes to carry out chemical reactions in an environmentally friendly manner. Enzymes can be used as biocatalyst in food and feed, pharmaceutical, textile, detergent and beverage industries, among others. Since industrial processes require harsh reaction conditions to be performed, these enzymes must possess several characteristics that make them suitable for this purpose. Currently the best option is to use enzymes from extremophilic microorganisms, particularly archaea because of their special characteristics, such as stability to elevated temperatures, extremes of pH, organic solvents, and high ionic strength. Extremozymes, are being used in biotechnological industry and improved through modern technologies, such as protein engineering for best performance. Despite the wide distribution of archaea, exist only few reports about these microorganisms isolated from Antarctica and very little is known about thermophilic or hyperthermophilic archaeal enzymes particularly from Antarctica. This review summarizes current knowledge of archaeal enzymes with biotechnological applications, including two extremozymes from Antarctic archaea with potential industrial use, which are being studied in our laboratory. Both enzymes have been discovered through conventional screening and genome sequencing, respectively. PMID- 30290808 TI - A randomized trial of dihydroartemisinin-piperaquine versus artemether lumefantrine for treatment of uncomplicated Plasmodium falciparum malaria in Mali. AB - BACKGROUND: Artemether-lumefantrine (AL) and artesunate-amodiaquine are first line treatment for uncomplicated malaria in many endemic countries, including Mali. Dihydroartemisinin-piperaquine (DHA-PQ) is also an alternative first-line artemisinin-based combination therapy, but only few data are available on DHA-PQ efficacy in sub-Saharan Africa. The main aim of this study was to compare clinical efficacy of DHA-PQ versus AL, using the World Health Organization (WHO) 42-day in vivo protocol. METHODS: The efficacy of three-dose regimens of DHA-PQ was compared to AL combination in a randomized, comparative open label trial using the WHO 42-day follow-up protocol from 2013 to 2015 in Doneguebougou and Torodo, Mali. The primary endpoint was to access the PCR-corrected Adequate Clinical and Parasitological Responses at day 28. RESULTS: A total of 317 uncomplicated malaria patients were enrolled, with 159 in DHA-PQ arm and 158 in AL arm. The parasite positivity rate decreased from 68.4% (95% CI 60.5-75.5) on day 1 to 3.8% (95% CI 1.4-8.1) on day 2 for DHA-PQ and 79.8% (95% CI 72.3-85.7) on day 1 to 9.5% (95% CI 5.4-15.2) on day 2 for AL, (p = 0.04). There was a significant difference in the uncorrected ACPR between DHA-PQ and AL, both at 28 day and 42-day follow-up with 97.4% (95% CI 93.5-99.3) in DHA-PQ vs 84.5% (95% CI 77.8-89.8) in AL (p < 0.001) and 94.2% (95% CI 89.3-97.3) in DHA-PQ vs 73.4% (95% CI 65.7-80.2) in AL, respectively (p < 0.001). After molecular correction, there was no significant difference in ACPRc between DHA-PQ and AL, both at the 28-day and 42-day follow-up with 99.4% (95% CI 96.5-100) in DHA-PQ versus 98.1% (95% CI 94.5-99.6) in AL (p = 0.3) and 99.3% (95% CI 96.5-100) in DHA-PQ vs 97.4% (95% CI 93.5-99.3) in AL (p = 0.2). There was no significant difference between DHA-PQ and AL in QTc prolongation 12.1% vs 7%, respectively (p = 0.4). CONCLUSION: The results showed that dihydroartemisinin-piperaquine and artemether-lumefantrine were clinically efficacious on Plasmodium falciparum parasites in Mali. PMID- 30290809 TI - Antiestrogen- and tamoxifen-induced effects on calcium-activated chloride currents in epithelial cells carrying the ?F508-CFTR point mutation. AB - BACKGROUND: Although pharmacological treatment has increased the average life expectancy of patients with cystic fibrosis, the median survival of females is shorter than that of males. In vitro and in vivo studies have shown that estrogens play a relevant role in the disease progression. The aim of this study was to investigate the effects of 17beta-estradiol and tamoxifen citrate (TMX) on calcium-activated chloride channel (CaCC) currents in human bronchial epithelial cells carrying the DeltaPhe508-CFTR mutation both in homozygosis and in heterozygosis. METHODS: Perforated patch clamp experiments were performed on single cells of the immortalized cell lines CFBE and IB3-1. Gramicidin (10 or 20 MUM) was added to the electrode solution to reach the whole cell configuration. The electrical stimulation protocol consisted of square voltages ranging from - 80 to + 80 mV, in steps of 20 mV and with a duration of 800 msec. RESULTS: The presence of 17beta-estradiol significantly reduced the CaCC currents, both in basal conditions and in the presence of ATP (100 MUM). The addition of TMX (10 MUM) completely restored the currents abolished by 17beta-estradiol, in basal conditions and after stimulation with ATP in both CFBE and IB3-1 cells. TMX had a strong, direct action on membrane current density, which significantly increased more than 4-fold in both cases. The membrane current stimulation produced by TMX was further enhanced by the addition of ATP. CFBE cells incubated for 24 h with 3 MUM VX-809 (a CFTR corrector) and then acutely stimulated with VX-770 (a CFTR potentiator) in the presence of forskolin, showed an increase of chloride currents which were abolished by Inh-172. The chloride current density induced by TMX + ATP was, on average, greater than that obtained with VX-809 + VX-770 + forskolin. The currents elicited by TMX + ATP were abolished by the addition of NPPB, a CaCC inhibitor. The combined administration of TMX/ATP and VXs/FSK had an additional effect on chloride currents. CONCLUSIONS: Our results show that TMX restores CaCC currents inhibited by 17beta-estradiol and directly activates the transmembrane chloride currents potentiated by ATP, an effect which is mutation independent. The combined effect of TMX with current used treatments for cystic fibrosis could be of benefit to patients. PMID- 30290810 TI - Association of serum high-density lipoprotein cholesterol with microalbuminuria in type 2 diabetes patients. AB - BACKGROUND: The association of serum high-density lipoprotein cholesterol (HDL-C) with microalbuminuria in type 2 diabetes mellitus (T2DM) remains controversial. Therefore, a cross-sectional study was conducted on patients with T2DM to investigate the relationship of HDL-C with microalbuminuria. METHODS: A total of 524 participants with T2DM were recruited in this cross-sectional study. The patients were divided into four groups according to serum HDL-C quartile. A nonparametric test was employed to assess the relationships across quartiles with clinical parameters and demographics. Multivariate logistic regression analysis was further performed. RESULTS: Of the 524 patients, 138 (26.3%) were found to have microalbuminuria by urinary albumin excretion rate determination. Serum HDL C levels in microalbuminuria group were significantly lower than those in non microalbuminuria group (1.04 (0.90-1.21) vs. 1.10 (0.94-1.31) mmol/L, P = 0.002). The nonparametric test for trend showed that the prevalence of microalbuminuria was significantly reduced for subjects of the fourth quartile of HDL-C compared to the first to third quartile (13.5% vs. 33.1%, 28.6%, 29.4%, P = 0.001). Multivariate logistic regression showed that subjects within the highest quartile of HDL-C had lower odds of microalbuminuria than those within the lowest quartile of HDL-C (OR = 0.17, 95% CI 0.15-0.52, P = 0.004). CONCLUSIONS: Higher levels of serum HDL-C were associated with decreased rates of microalbuminuria in T2DM patients. PMID- 30290812 TI - Health and sustainable development; strengthening peri-operative care in low income countries to improve maternal and neonatal outcomes. AB - BACKGROUND: Uganda is far from meeting the sustainable development goals on maternal and neonatal mortality with a maternal mortality ratio of 383/100,000 live births, and 33% of the women gave birth by 18 years. The neonatal mortality ratio was 29/1000 live births and 96 stillbirths occur every day due to placental abruption, and/or eclampsia - preeclampsia and other unkown causes. These deaths could be reduced with access to timely safe surgery and safe anaesthesia if the Comprehensive Emergency Obstetric and Newborn Care services (CEmONC), and appropriate intensive care post operatively were implemented. A 2013 multi national survey by Epiu et al. showed that, the Safe Surgical Checklist was not available for use at main referral hospitals in East Africa. We, therefore, set out to further assess 64 government and private hospitals in Uganda for the availability and usage of the WHO Checklists, and investigate the post-operative care of paturients; to advocate for CEmONC implementation in similarly burdened low income countries. METHODS: The cross-sectional survey was conducted at 64 government and private hospitals in Uganda using preset questionnaires. RESULTS: We surveyed 41% of all hospitals in Uganda: 100% of the government regional referral hospitals, 16% of government district hospitals and 33% of all private hospitals. Only 22/64 (34.38%: 95% CI = 23.56-47.09) used the WHO Safe Surgical Checklist. Additionally, only 6% of the government hospitals and 14% not-for profit hospitals had access to Intensive Care Unit (ICU) services for postoperative care compared to 57% of the private hospitals. CONCLUSIONS: There is urgent need to make WHO checklists available and operationalized. Strengthening peri-operative care in obstetrics would decrease maternal and neonatal morbidity and move closer to the goal of safe motherhood working towards Universal Health Care. PMID- 30290811 TI - A new ALK isoform transported by extracellular vesicles confers drug resistance to melanoma cells. AB - BACKGROUND: Drug resistance remains an unsolved clinical issue in oncology. Despite promising initial responses obtained with BRAF and MEK kinase inhibitors, resistance to treatment develops within months in virtually all melanoma patients. METHODS: Microarray analyses were performed in BRAF inhibitor-sensitive and resistant cell lines to identify changes in the transcriptome that might play a role in resistance. siRNA approaches and kinase inhibitors were used to assess the involvement of the identified Anaplastic Lymphoma Kinase (ALK) in drug resistance. The capability of extracellular vesicles (EVs) to transfer drug resistant properties was investigated in co-culture assays. RESULTS: Here, we report a new mechanism of acquired drug resistance involving the activation of a novel truncated form of ALK. Knock down or inhibition of ALK re-sensitised resistant cells to BRAF inhibition and induced apoptosis. Interestingly, truncated ALK was also secreted into EVs and we show that EVs were the vehicle for transferring drug resistance. CONCLUSIONS: To our knowledge, this is the first report demonstrating the functional involvement of EVs in melanoma drug resistance by transporting a truncated but functional form of ALK, able to activate the MAPK signalling pathway in target cells. Combined inhibition of ALK and BRAF dramatically reduced tumour growth in vivo. These findings make ALK a promising clinical target in melanoma patients. PMID- 30290814 TI - Numerical simulation of embryo transfer: how the viscosity of transferred medium affects the transport of embryos. AB - BACKGROUND: Embryo transfer (ET) is a key step of assisted reproductive procedures, where the transferred medium containing the embryos is injected into the uterine cavity through a transcervical catheter and blended with intrauterine fluid in the uterine cavity. This procedure determines the delivery sites of embryos in the uterine cavity and has crucial impact on the implantation. Due to practical restrictions and ethical issues, it is often difficult to perform an in vivo study in humans to examine factors that affect the motions and delivery of embryos during ET. Alternatively, mathematical modeling is a powerful tool to that end. RESULTS: A computational model is developed to simulate the intrauterine mixing flow and track the embryo motions. Two important factors affecting the intrauterine flow are studied via this model: the viscosity of the transferred medium and the injection speed. Numerical results show that the dispersion pattern and the final delivery sites of the embryos are significantly influenced by the viscosity of the transferred medium. Specially, increasing the transferred medium viscosity close to that of the uterine fluid can enhance the probability that the embryos are delivered close to the fundus and keep them from being dragged backward to the cervix during catheter withdrawal. In addition, a slow injection speed can lower the driving force on the embryo during ET, which can prevent the embryo from being injured. CONCLUSIONS: Based on our study, the practice of using a transferred medium with similar viscosity to that of the uterine fluid and a slow injection speed is recommended for real embryo transfer procedures in clinic. PMID- 30290813 TI - Does it take three to tango? An unsuspected multimorbidity of CD8+ T cell lymphoproliferative disorder, malaria, and EBV infection. AB - BACKGROUND: Malaria is known to cause acute and deadly complications. However, malaria can cause unforeseen pathologies due to its chronicity. It increases the risk of endemic Burkitt Lymphoma development by inducing DNA damage in germinal centre (GC) B cells, and leading higher frequency of Epstein-Barr virus (EBV) infected cells in GCs. EBV is well known for its tropism for B cells. However, less is known about EBV's interaction with T cells and its association with T cell lymphoma. CASE PRESENTATION: A 43-year-old Sudanese male admitted to hospital in Istanbul, Turkey, a non-endemic country, with hyperpigmented painful skin rashes on his whole body. A complete blood count and a peripheral blood smear during admission revealed large granular lymphocytes (LGLs) with abnormally higher CD8 T cell numbers. Additional skin biopsy and pathology results were compatible with CD8+ T cell lymphoproliferative disorder with skin involvement. Patient was treated and discharged. However, a pathologist noticed unusual structures in skin tissue samples. Careful evaluation of skin biopsy samples by polarized microscopy revealed birefringent crystalloid structures resembling malarial haemozoin mainly loaded in macrophages and giant histiocytes. After purification of DNA from the skin biopsy samples, nested PCR was performed for the detection of Plasmodium parasites and Plasmodium falciparum DNA was amplified. Because, the co-presence of EBV infection with malaria is a well-known aetiology of lymphoma, EBV-early RNA (EBER) transcripts were investigated in paraffin-embedded tissue samples and found to be positive in macrophage-like histiocytes. CONCLUSIONS: This is a unique case of malaria and EBV infection in a T-LGL lymphoma patient who presented in a non-endemic country. This case emphasizes the clinical importance of EBV monitoring in T-LGL patients with skin involvement. Notably, Plasmodium infection should be examined in patients from malaria endemic regions by pathological and molecular investigations. PMID- 30290816 TI - Dietary patterns of university students in the UK: a cross-sectional study. AB - BACKGROUND: University represents a key transition into adulthood for many adolescents but there are associated concerns about health and behaviours. One important aspect relates to diet and there is emerging evidence that university students may consume poor quality diets, with potential implications for body weight and long-term health. This research aimed to characterise dietary patterns of university students in the UK and their sociodemographic and lifestyle antecedents. METHODS: An online, cross-sectional survey was undertaken with a convenience sample of 1448 university students from five UK universities (King's College London, Universities of St Andrews, Southampton and Sheffield, and Ulster University). The survey comprised a validated food frequency questionnaire alongside lifestyle and sociodemographic questions. Dietary patterns were generated from food frequency intake data using principal components analysis. Nutrient intakes were estimated to characterise the nutrient profile of each dietary pattern. Associations with sociodemographic variables were assessed through general linear modelling. RESULTS: Dietary analyses revealed four major dietary patterns: 'vegetarian'; 'snacking'; 'health-conscious'; and 'convenience, red meat & alcohol'. The 'health-conscious' pattern had the most favourable micronutrient profile. Students' gender, age, year of study, geographical location and cooking ability were associated with differences in pattern behaviour. Female students favoured the 'vegetarian' pattern, whilst male students preferred the 'convenience, red meat & alcohol' pattern. Less healthful dietary patterns were positively associated with lifestyle risk factors such as smoking, low physical activity and take-away consumption. The health-conscious pattern had greatest nutrient density. The 'convenience, red meat & alcohol' pattern was associated with higher weekly food spending; this pattern was also identified most consistently across universities. Students reporting greater cooking ability tended towards the 'vegetarian' and 'health-conscious' patterns. CONCLUSIONS: Food intake varied amongst university students. A substantial proportion of students followed health-promoting diets, which had good nutrient profiles obviating a need for dietary intervention. However, some students consumed poor diets, incurred greater food costs and practised unfavourable lifestyle behaviours, which may have long-term health effects. University policy to improve students' diets should incorporate efforts to promote student engagement in cooking and food preparation, and increased availability of low cost healthier food items. PMID- 30290815 TI - malariaAtlas: an R interface to global malariometric data hosted by the Malaria Atlas Project. AB - BACKGROUND: The Malaria Atlas Project (MAP) has worked to assemble and maintain a global open-access database of spatial malariometric data for over a decade. This data spans various formats and topics, including: geo-located surveys of malaria parasite rate; global administrative boundary shapefiles; and global and regional rasters representing the distribution of malaria and associated illnesses, blood disorders, and intervention coverage. MAP has recently released malariaAtlas, an R package providing a direct interface to MAP's routinely-updated malariometric databases and research outputs. METHODS AND RESULTS: The current paper reviews the functionality available in malariaAtlas and highlights its utility for spatial epidemiological analysis of malaria. malariaAtlas enables users to freely download, visualise and analyse global malariometric data within R. Currently available data types include: malaria parasite rate and vector occurrence point data; subnational administrative boundary shapefiles; and a large suite of rasters covering a diverse range of metrics related to malaria research. malariaAtlas is here used in two mock analyses to illustrate how this data may be incorporated into a standard R workflow for spatial analysis. CONCLUSIONS: malariaAtlas is the first open-access R-interface to malariometric data, providing a new and reproducible means of accessing such data within a freely available and commonly used statistical software environment. In this way, the malariaAtlas package aims to contribute to the environment of data-sharing within the malaria research community. PMID- 30290817 TI - Elevated serum soluble programmed cell death ligand 1 concentration as a potential marker for poor prognosis in small cell lung cancer patients with chemotherapy. AB - BACKGROUND: Potential relationship between serum soluble programmed cell death ligand 1 and prognosis of small cell lung cancer is not well explored. The aim of the study was to reveal the prognostic significance of serum soluble programmed cell death ligand 1 in patients with small cell lung cancer. METHODS: A total of 250 small cell lung cancer patients and 250 controls were included. Research information was obtained from their medical records. Blood samples were collected on admission. Serum concentration of programmed cell death ligand 1 was measured using Enzyme-Linked Immunosorbent Assay. The patients underwent cisplatin etoposide chemotherapy with a maximum of six cycles. Subsequently, they were followed-up for 12 months, and therapeutic response and cancer death were recorded. RESULTS: Serum concentration of programmed cell death ligand 1 was higher in the patients than in the controls on admission (P < 0.001). After chemotherapy, 112 patients had no response to this therapy. In the 12-month follow up period, 118 patients died due to this cancer. Multivariate Cox regression model revealed that the higher serum concentration of programmed cell death ligand 1 on admission was associated with the higher risk of no response to chemotherapy or cancer caused death (HR: 1.40, 95% CI: 1.05 ~ 1.87; HR: 1.43, 95% CI: 1.08 ~ 1.87). CONCLUSION: Elevated serum concentration of soluble programmed cell death ligand 1 might be an independent risk factor for non-response to chemotherapy and cancer caused death in small cell lung cancer patients. PMID- 30290818 TI - End-of-life situations in cardiology: a qualitative study of physicians' and nurses' experience in a large university hospital. AB - BACKGROUND: Professional societies call for integration of end-of-life discussions early in the trajectory of heart failure, yet it remains unclear where current practices stand in relation to these recommendations. We sought to describe the perceptions and attitudes of caregivers in cardiology regarding end of-life situations. METHODS: We performed a qualitative study using semi directive interviews in the cardiology department of a university teaching hospital in France. Physicians, nurses and nurses' aides working full-time in the department at the time of the study were eligible. Participants were asked to describe how they experienced end-of-life situations. Interviews were recorded, transcribed and coded using thematic analysis to identify major and secondary themes. RESULTS: All physicians (N = 16)(average age 43.5 +/- 13 years), 16 nurses (average age 38.5 +/- 7.6 years) and 5 nurses' aides (average age 49 +/- 7.8 years) participated. Interviews were held between 30 March and 17 July 2017. The main themes to emerge from the physicians' discourse were the concept of cardiology being a very active discipline, and a very curative frame of mind was prevalent. Communication (with paramedical staff, patients and families) was deemed to be important. Advance directives were thought to be rare, and not especially useful. Nurses also reported communication as a major issue, but their form of communication is bounded by several factors (physicians' prior discourse, legislation). They commonly engage in reconciling: between the approach (curative or palliative) and the reality of the treatment prescribed; performing curative interventions in patients they deem to be dying cases causes them distress. The emergency context prevents nurses from taking the time necessary to engage in end of-life discussions. They engage in comfort-giving behaviors to maximize patient comfort. CONCLUSION: Current perceptions and practices vis-a-vis end-of-life situations in our department are individual, heterogeneous and not yet aligned with recommendations of professional societies. PMID- 30290819 TI - Anatomical basis for the choice of laparoscopic surgery for low rectal cancer through the pelvic imaging data-a cohort study. AB - BACKGROUND: Low rectal cancer surgery without anus conservation needs permanent ileostomy or colostomy which seriously affects the quality of life of patients. Therefore, low rectal cancer surgery not only pays attention to the safety of surgical treatment but also to the anus conservation. METHODS: Sixty-seven patients suffering from low rectal cancer had undergone laparoscopic surgery which was analyzed through retrospective study. They were divided into the anus conserving and non-anus-conserving groups. Thirty-five set of pelvic data was obtained from the preoperative CT and MRI images. After that, the discriminant function was obtained to predict the surgery methods for patients with low rectal carcinoma. RESULTS: Anal-conserving group discriminant function (F1) = - 33.698 + 6.045 * anal margin distance (cm) + 1.105 * T4; non-anus-conserving group discriminant function (F2) = - 14.125 + 3.138 * anal margin distance (cm) + 0.804 * T4. If F1 is greater than F2, then the case can be treated as the anus reservation while if F2 is greater than F1 the case cannot be treated anus reservation. The accuracy of the discriminant function was evaluated which was found to be 97%. CONCLUSION: The discriminant function of pelvic data provides anatomical basis for the choice of surgical methods for low rectal cancer. PMID- 30290820 TI - The analgesic effects of buprenorphine (Vetergesic or Simbadol) in combination with carprofen in dogs undergoing ovariohysterectomy: a randomized, blinded, clinical trial. AB - BACKGROUND: Buprenorphine is a potent lipophilic opioid analgesic that is largely used in the multimodal treatment of acute pain. Simbadol (buprenorphine hydrochloride) is the first and only FDA-approved high-concentration formulation of buprenorphine for use in cats. The aim of this study was to evaluate the analgesic efficacy of carprofen in combination with one of two commercial formulations of buprenorphine (Simbadol and Vetergesic, 1.8 mg/mL and 0.3 mg/mL, respectively) in dogs undergoing ovariohysterectomy. Twenty-four dogs were included in a randomized, prospective, controlled, clinical trial. Patients were randomly divided into 2 groups as follows. Dogs were premedicated with acepromazine (0.02 mg/kg) and either 0.02 mg/kg of Vetergesic or Simbadol intramuscularly (Vetergesic group - VG; Simbadol group - SG, respectively; n = 12/group). General anesthesia was induced with propofol and maintained with isoflurane in 100% oxygen. Carprofen (4.4 mg/kg SC) was administered after induction of anesthesia. Heart rate, respiratory rate, blood pressure, pulse oximetry, pain scores using the Glasgow Composite Pain Scale Short Form (CMPS SF), sedation scores using a dynamic interactive visual analogue scale and adverse events were evaluated before and after ovariohysterectomy by an observer who was unaware of treatment administration. If CMPS-SF scores were >= 5/20, dogs were administered rescue analgesia (morphine 0.5 mg/kg IM). Statistical analysis was performed using linear mixed models and Fisher's exact test (p < 0.05). RESULTS: Pain and sedation scores and physiological parameters were not significantly different between treatments. Three dogs in VG (25%) and none in SG (0%) required rescue analgesia (p = 0.109). Adverse effects (i.e. vomiting and melena) were observed in two dogs in SG and were thought to be related to stress and/or nonsteroidal anti-inflammatory drug toxicity. CONCLUSIONS: The administration of buprenorphine with carprofen preoperatively provided adequate postoperative analgesia for the majority of dogs undergoing OVH without serious adverse events. Prevalence of rescue analgesia was not significantly different between groups; however, it could be clinically relevant and explained by a type II error (i.e. small sample size). Future studies are necessary to determine if analgesic efficacy after Simbadol and Vetergesic is related to individual variability or pharmacokinetic differences. PMID- 30290821 TI - Liposomal formulations of carboplatin injected by convection-enhanced delivery increases the median survival time of F98 glioma bearing rats. AB - BACKGROUND: Effectiveness of chemotherapy for treating glioblastoma (GBM) brain tumors is hampered by the blood-brain barrier which limits the entry into the brain of most drugs from the blood. To bypass this barrier, convection-enhanced delivery (CED) was proposed to directly inject drugs in tumor. However, the benefit of CED may be hampered when drugs diffuse outside the tumor to then induce neurotoxicity. Encapsulation of drugs into liposome aims at increasing tumor cells specificity and reduces neurotoxicity. However, the most appropriate liposomal formulation to inject drugs into brain tumor by CED still remains to be determined. In this study, four liposomal carboplatin formulations were prepared and tested in vitro on F98 glioma cells and in Fischer rats carrying F98 tumor implanted in the brain. Impact of pegylation on liposomal surface and relevance of positive or negative charge were assessed. RESULTS: The cationic non-pegylated (L1) and pegylated (L2) liposomes greatly improved the toxicity of carboplatin in vitro compared to free carboplatin, whereas only a modest improvement and even a reduction of efficiency were measured with the anionic non-pegylated (L3) and the pegylated (L4) liposomes. Conversely, only the L4 liposome significantly increased the median survival time of Fisher rats implanted with the F98 tumor, compared to free carboplatin. Neurotoxicity assays performed with the empty L4' liposome showed that the lipid components of L4 were not toxic. These results suggest that the positive charge on liposomes L1 and L2, which is known to promote binding to cell membrane, facilitates carboplatin accumulation in cancer cells explaining their higher efficacy in vitro. Conversely, negatively charged and pegylated liposome (L4) seems to diffuse over a larger distance in the tumor, and consequently significantly increased the median survival time of the animals. CONCLUSIONS: Selection of the best liposomal formulation based on in vitro studies or animal model can result in contradictory conclusions. The negatively charged and pegylated liposome (L4) which was the less efficient formulation in vitro showed the best therapeutic effect in animal model of GBM. These results support that relevant animal model of GBM must be considered to determine the optimal physicochemical properties of liposomal formulations. PMID- 30290822 TI - Self-nanoemulsifying system improves oral absorption and enhances anti-acute myeloid leukemia activity of berberine. AB - BACKGROUND: Recently, we found that berberine (BBR) exerts anti-acute myeloid leukemia activity, particularly toward high-risk and relapsed/refractory acute myeloid leukemia MV4-11 cells in vitro. However, the poor water solubility and low bioavailability observed with oral BBR administration has limited its clinical use. Therefore, we design and develop a novel oil-in-water self nanoemulsifying system for BBR (BBR SNE) to improve oral bioavailability and enhance BBR efficacy against acute myeloid leukemia by greatly improving its solubility. RESULTS: This system (size 23.50 +/- 1.67 nm, zeta potential - 3.35 +/- 0.03 mV) was prepared with RH40 (surfactant), 1,2-propanediol (co surfactant), squalene (oil) and BBR using low-energy emulsification methods. The system loaded BBR successfully according to thermal gravimetric, differential scanning calorimetry, and Fourier transform infrared spectroscopy analyses. The release profile results showed that BBR SNE released BBR more slowly than BBR solution. The relative oral bioavailability of this novel system in rabbits was significantly enhanced by 3.41-fold over that of BBR. Furthermore, Caco-2 cell monolayer transport studies showed that this system could help enhance permeation and prevent efflux of BBR. Importantly, mice with BBR SNE treatment had significantly longer survival time than BBR-treated mice (P < 0.001) in an MV4-11 engrafted leukemia murine model. CONCLUSIONS: These studies confirmed that BBR SNE is a promising therapy for acute myeloid leukemia. PMID- 30290823 TI - Identifying patterns of care for elderly patients with non-surgically treated stage III non-small cell lung cancer: an analysis of the national cancer database. AB - BACKGROUND: To compare patterns of care for elderly patients versus non-elderly patients with non-surgically treated stage III non-small cell lung cancer (NSCLC) using the National Cancer Database (NCDB). We hypothesize that elderly patients are less likely to receive curative treatments, including concurrent chemoradiation (CCRT), compared to non-elderly patients. METHODS: We identified patients from the NCDB between 2003 and 2014 with non-surgically treated stage III NSCLC. We defined elderly as >=70 years old and non-elderly <70 years old. Treatment categories included: no treatment, palliative treatment (chemotherapy alone, radiation (RT) alone <59.4 Gy or chemoradiation (CRT) <59.4 Gy), or definitive treatment (RT alone >=59.4 Gy or CRT >=59.4 Gy). Differences in treatment between elderly and non-elderly were tested using the chi2 test. RESULTS: We identified 57,602 elderly and 55,928 non-elderly patients. More elderly patients received no treatment (24.5% vs. 13.2%, P < 0.0001) and the elderly were less likely to receive definitive treatment (48.5% vs. 56.3%, P < 0.0001). CCRT was delivered in a significantly smaller proportion of elderly vs. non-elderly patients (66.0% vs. 78.9%, P < 0.0001 in patients treated with definitive intent; 32.0% vs. 44.5%, P < 0.0001 in patients receiving any treatment; and 24.2% vs. 38.6%, P < 0.0001 amongst all patients). CONCLUSIONS: In this large study of patients with non-surgically treated stage III NSCLC, elderly patients were less likely to receive any treatment or treatment with definitive intent compared to the non-elderly. The lack of use of concurrent or sequential chemotherapy in the elderly with stage III NSCLC suggests that the optimal treatment approach for this vulnerable population remains undefined. PMID- 30290824 TI - Influences on students' empathy in medical education: an exploratory interview study with medical students in their third and last year. AB - BACKGROUND: Empathy is beneficial for patients and physicians. It facilitates treatment and improves physical and psychosocial outcomes. The therapeutic relevance of empathy emphasizes the need to help medical students develop their empathic abilities. Our study aimed to identify factors which promote or hinder the development and expression of empathy in medical students during the course of their studies. METHODS: We interviewed 24 medical students (six male and six female students in their 6th semester as well as six male and six female students in their final clinical year) using semi-structured interviews. The interviews were recorded, transcribed verbatim and analyzed using Braun & Clarke's thematic analysis. RESULTS: We identified four main themes influencing the development and expression of empathy. 1) Course of studies: hands-on-experience, role models, science and theory, and emphasis on the importance of empathy; 2) students: insecurities and lack of routine, increasing professionalism, previous work experiences, professional distance, mood, maturity, and personal level of empathy; 3) patients: "easy" and "difficult" patients including their state of health; and 4) surrounding conditions: time pressure/stress, work environment, and job dissatisfaction. CONCLUSIONS: The development and use of empathy could be promoted by increasing: hands-on-experiences, possibilities to experience the patient's point of view and offering patient contact early in the curriculum. Students need support in reflecting on their actions, behavior and experiences with patients. Instructors need time and opportunities to reflect on their own communication with and treatment of patients, on their teaching behavior, and on their function as role models for treating patients empathically and preventing stress. Practical experiences should be made less stressful for students. The current changes implemented in some medical school curriculums (e.g., in Germany) seem to go in the right direction by integrating patient contact early on in the curriculum and focusing more on teaching adequate communication and interaction behaviors.

PMID- 30290825 TI - Efficacy of artemether-lumefantrine and dihydroartemisinin-piperaquine for the treatment of uncomplicated malaria in Papua New Guinea. AB - BACKGROUND: In 2009, the Papua New Guinea (PNG) Department of Health adopted artemether-lumefantrine (AL) and dihydroartemisinin-piperaquine (DHA-PPQ) as the first- and second-line treatments for uncomplicated malaria, respectively. This study was conducted to assess the efficacy of both drugs following adoption of the new policy. METHODS: Between June 2012 and September 2014, a therapeutic efficacy study was conducted in East Sepik and Milne Bay Provinces of PNG in accordance with the standard World Health Organization (WHO) protocol for surveillance of anti-malarial drug efficacy. Patients >= 6 months of age with microscopy confirmed Plasmodium falciparum or Plasmodium vivax mono-infections were enrolled, treated with AL or DHA-PPQ, and followed up for 42 days. Study endpoints were adequate clinical and parasitological response (ACPR) on days 28 and 42. The in vitro efficacy of anti-malarials and the prevalence of selected molecular markers of resistance were also determined. RESULTS: A total of 274 P. falciparum and 70 P. vivax cases were enrolled. The day-42 PCR-corrected ACPR for P. falciparum was 98.1% (104/106) for AL and 100% (135/135) for DHA-PPQ. The day 42 PCR-corrected ACPR for P. vivax was 79.0% (15/19) for AL and 92.3% (36/39) for DHA-PPQ. Day 3 parasite clearance of P. falciparum was 99.2% with AL and 100% with DHA-PPQ. In vitro testing of 96 samples revealed low susceptibility to chloroquine (34% of samples above IC50 threshold) but not to lumefantrine (0%). Molecular markers assessed in a sub-set of the study population indicated high rates of chloroquine resistance in P. falciparum (pfcrt SVMNT: 94.2%, n = 104) and in P. vivax (pvmdr1 Y976F: 64.8%, n = 54). CONCLUSIONS: AL and DHA-PPQ were efficacious as first- and second-line treatments for uncomplicated malaria in PNG. Continued in vivo efficacy monitoring is warranted considering the threat of resistance to artemisinin and partner drugs in the region and scale-up of artemisinin-based combination therapy in PNG. PMID- 30290827 TI - Focal ischemic stroke leads to lung injury and reduces alveolar macrophage phagocytic capability in rats. AB - BACKGROUND: Ischemic stroke causes brain inflammation, which we postulate may result in lung damage. Several studies have focused on stroke-induced immunosuppression and lung infection; however, the possibility that strokes may trigger lung inflammation has been overlooked. We hypothesized that even focal ischemic stroke might induce acute systemic and pulmonary inflammation, thus altering respiratory parameters, lung tissue integrity, and alveolar macrophage behavior. METHODS: Forty-eight Wistar rats were randomly assigned to ischemic stroke (Stroke) or sham surgery (Sham). Lung function, histology, and inflammation in the lung, brain, bronchoalveolar lavage fluid (BALF), and circulating plasma were evaluated at 24 h. In vitro, alveolar macrophages from naive rats (unstimulated) were exposed to serum or BALF from Sham or Stroke animals to elucidate possible mechanisms underlying alterations in alveolar macrophage phagocytic capability. Alveolar macrophages and epithelial and endothelial cells of Sham and Stroke animals were also isolated for evaluation of mRNA expression of interleukin (IL)-6 and tumor necrosis factor (TNF)-alpha. RESULTS: Twenty-four hours following ischemic stroke, the tidal volume, expiratory time, and mean inspiratory flow were increased. Compared to Sham animals, the respiratory rate and duty cycle during spontaneous breathing were reduced, but this did not affect lung mechanics during mechanical ventilation. Lungs from Stroke animals showed clear evidence of increased diffuse alveolar damage, pulmonary edema, and inflammation markers. This was associated with an increase in ultrastructural damage, as evidenced by injury to type 2 pneumocytes and endothelial cells, cellular infiltration, and enlarged basement membrane thickness. Protein levels of proinflammatory mediators were documented in the lung, brain, and plasma (TNF-alpha and IL-6) and in BALF (TNF-alpha). The phagocytic ability of macrophages was significantly reduced. Unstimulated macrophages isolated from naive rats only upregulated expression of TNF-alpha and IL-6 following exposure to serum from Stroke rats. Exposure to BALF from Stroke or Sham animals did not change alveolar macrophage behavior, or gene expression of TNF-alpha and IL-6. IL-6 expression was increased in macrophages and endothelial cells from Stroke animals. CONCLUSIONS: In rats, focal ischemic stroke is associated with brain-lung crosstalk, leading to increased pulmonary damage and inflammation, as well as reduced alveolar macrophage phagocytic capability, which seems to be promoted by systemic inflammation. PMID- 30290829 TI - Noise in the intensive care unit and its influence on sleep quality: a multicenter observational study in Dutch intensive care units. AB - BACKGROUND: High noise levels in the intensive care unit (ICU) are a well-known problem. Little is known about the effect of noise on sleep quality in ICU patients. The study aim is to determine the effect of noise on subjective sleep quality. METHODS: This was a multicenter observational study in six Dutch ICUs. Noise recording equipment was installed in 2-4 rooms per ICU. Adult patients were eligible for the study 48 h after ICU admission and were followed up to maximum of five nights in the ICU. Exclusion criteria were presence of delirium and/or inability to be assessed for sleep quality. Sleep was evaluated using the Richards Campbell Sleep Questionnaire (range 0-100 mm). Noise recordings were used for analysis of various auditory parameters, including the number and duration of restorative periods. Hierarchical mixed model regression analysis was used to determine associations between noise and sleep. RESULTS: In total, 64 patients (68% male), mean age 63.9 (+/- 11.7) years and mean Acute Physiology And Chronic Health Evaluation (APACHE) II score 21.1 (+/- 7.1) were included. Average sleep quality score was 56 +/- 24 mm. The mean of the 24-h average sound pressure levels (LAeq, 24h) was 54.0 dBA (+/- 2.4). Mixed-effects regression analyses showed that background noise (beta = - 0.51, p < 0.05) had a negative impact on sleep quality, whereas number of restorative periods (beta = 0.53, p < 0.01) and female sex (beta = 1.25, p < 0.01) were weakly but significantly correlated with sleep. CONCLUSIONS: Noise levels are negatively associated and restorative periods and female gender are positively associated with subjective sleep quality in ICU patients. TRIAL REGISTRATION: www.ClinicalTrials.gov, NCT01826799 . Registered on 9 April 2013. PMID- 30290828 TI - Decoding the role of TET family dioxygenases in lineage specification. AB - Since the discovery of methylcytosine oxidase ten-eleven translocation (TET) proteins, we have witnessed an exponential increase in studies examining their roles in epigenetic regulation. TET family proteins catalyze the sequential oxidation of 5-methylcytosine (5mC) to oxidized methylcytosines including 5 hydroxymethylcytosine (5hmC), 5-formylcytosine, and 5-carboxylcytosine. TETs contribute to the regulation of lineage-specific gene expression via modulating DNA 5mC/5hmC balances at the proximal and distal regulatory elements of cell identity genes, and therefore enhance chromatin accessibility and gene transcription. Emerging evidence suggests that TET dioxygenases participate in the establishment and/or maintenance of hypomethylated bivalent domains at multiple differentiation-associated genes, and thus ensure developmental plasticity. Here, we review the current state of knowledge concerning TET family proteins, DNA hydroxymethylation, their distribution, and function in endoderm, mesoderm, and neuroectoderm specification. We will summarize the evidence pertaining to their crucial regulatory roles in lineage commitment and development. PMID- 30290830 TI - Reconstruction of avian ancestral karyotypes reveals differences in the evolutionary history of macro- and microchromosomes. AB - BACKGROUND: Reconstruction of ancestral karyotypes is critical for our understanding of genome evolution, allowing for the identification of the gross changes that shaped extant genomes. The identification of such changes and their time of occurrence can shed light on the biology of each species, clade and their evolutionary history. However, this is impeded by both the fragmented nature of the majority of genome assemblies and the limitations of the available software to work with them. These limitations are particularly apparent in birds, with only 10 chromosome-level assemblies reported thus far. Algorithmic approaches applied to fragmented genome assemblies can nonetheless help define patterns of chromosomal change in defined taxonomic groups. RESULTS: Here, we make use of the DESCHRAMBLER algorithm to perform the first large-scale study of ancestral chromosome structure and evolution in birds. This algorithm allows us to reconstruct the overall genome structure of 14 key nodes of avian evolution from the Avian ancestor to the ancestor of the Estrildidae, Thraupidae and Fringillidae families. CONCLUSIONS: Analysis of these reconstructions provides important insights into the variability of rearrangement rates during avian evolution and allows the detection of patterns related to the chromosome distribution of evolutionary breakpoint regions. Moreover, the inclusion of microchromosomes in our reconstructions allows us to provide novel insights into the evolution of these avian chromosomes, specifically.

Pregnant patients performed a self-collected vaginal swab, then underwent a provider collected swab via speculum exam. DNA pyrosequencing of the 16S rRNA gene V1V3 and V3V5 variable regions was performed. Relative abundance of taxa, alpha diversity, and beta diversity of patient- and provider-collected swabs were compared. RESULTS: Ninety-four vaginal swabs from 47 women were analyzed. On non metric multi-dimensional scaling plots, paired patient- and provider-collected swabs clustered closely. The median Pearson correlation coefficient was 0.993 (interquartile range 0.951-0.999) for V1V3 and 0.987 (interquartile range 0.902 0.999) for V3V5. Among paired V1V3 and V3V5 sequences, 83.0% and 73.9% showed strong Pearson correlation (> 0.9), respectively, between patient- and provider collected swabs; V1V3 and V3V5 sequences with weaker Pearson correlation (< 0.9) had correlation coefficients 0.57-0.89 and 0.49-0.89, respectively. No taxa were preferentially detected by sampling method, with relative abundance of taxa highly conserved. No significant difference in Shannon diversity for V1V3 (p = 0.22) and V3V5 (p = 0.11) sequences among paired samples was seen. We demonstrate that bacterial communities defined from patient- and provider-collected vaginal swabs in pregnant women are similar, validating utilization of patient-collected swabs for vaginal bacterial microbiome sampling during pregnancy. PMID- 30290832 TI - Long-term exposure to road traffic noise and incidence of breast cancer: a cohort study. AB - BACKGROUND: Exposure to road traffic noise was associated with increased risk of estrogen receptor (ER)-negative (ER-) breast cancer in a previous cohort study, but not with overall or ER-positive (ER+) breast cancer, or breast cancer prognosis. We examined the association between long-term exposure to road traffic noise and incidence of breast cancer, overall and by ER and progesterone receptor (PR) status. METHODS: We used the data from a nationwide Danish Nurse Cohort on 22,466 female nurses (age > 44 years) who at recruitment in 1993 or 1999 reported information on breast cancer risk factors. We obtained data on the incidence of breast cancer from the Danish Cancer Registry, and on breast cancer subtypes by ER and PR status from the Danish Breast Cancer Cooperative Group, up to 31 December 2012. Road traffic noise levels at the nurses' residences were estimated by the Nord2000 method between 1970 and 2013 as annual means of a weighted 24 h average (Lden) at the most exposed facade. We used time-varying Cox regression to analyze the associations between the 24-year, 10-year, and 1-year mean of Lden and breast cancer, separately for total breast cancer and by ER and PR status. RESULTS: Of the 22,466 women, 1193 developed breast cancer in total during 353,775 person-years of follow up, of whom 611 had complete information on ER and PR status. For each 10 dB increase in 24-year mean noise levels at their residence, we found a statistically significant 10% (hazard ratio and 95% confidence interval 1.10; 1.00-1.20) increase in total breast cancer incidence and a 17% (1.17; 1.02-1.33) increase in analyses based on 611 breast cancer cases with complete ER and PR information. We found positive, statistically significant association between noise levels and ER+ (1.23; 1.06-1.43, N = 494) but not ER- (0.93; 0.70-1.25, N = 117) breast cancers, and a stronger association between noise levels and PR+ (1.21; 1.02-1.42, N = 393) than between noise levels and PR- (1.10; 0.89-1.37, N = 218) breast cancers. Association between noise and ER+ breast cancer was statistically significantly stronger in nurses working night shifts (3.36; 1.48-7.63) than in those not working at night (1.21; 1.02-1.43) (p value for interaction = 0.05). CONCLUSION: Long-term exposure to road traffic noise may increase risk of ER+ breast cancer. PMID- 30290834 TI - Comparing lethal dose ratios using probit regression with arbitrary slopes. AB - BACKGROUND: Evaluating the toxicity or effectiveness of two or more toxicants in a specific population often requires specialized statistical software to calculate and compare median lethal doses (LD50s). Tests for equality of LD50s using probit regression with parallel slopes have been implemented in many software packages, while tests for cases of arbitrary slopes are not generally available. METHODS: In this study, we established probit-log(dose) regression models and solved them by the maximum likelihood method using Microsoft Excel. The z- and chi2-tests were used to assess significance and goodness of fit to the probit regression models, respectively. We calculated the lethal doses (LDs) of the toxicants at different significance levels and their 95% confidence limits (CLs) based on an accurate estimation of log(LD) variances. We further calculated lethal dose ratios and their 95% CLs for two examples without assuming parallel slopes following the method described by Robertson, et al., 2017. RESULTS: We selected representative toxicology datasets from the literature as case studies. For datasets without natural responses in the control group, the slopes, intercepts, chi2 statistics and LDs calculated using our method were identical to those calculated using Polo-Plus and SPSS software, and the 95% CLs of the lethal dose ratios between toxicants were close to those calculated using Polo-Plus. For datasets that included natural responses in the control group, our results were also close to those calculated using Polo-Plus and SPSS. CONCLUSION: This procedure yielded accurate estimates of lethal doses and 95% CLs at different significance levels as well as the lethal dose ratios and 95% CLs between two examples. The procedure could be used to assess differences in the toxicities of two examples without the assumption of parallelism between probit-log(dose) regression lines. PMID- 30290835 TI - A rare case of large pyosalpinx in an elderly patient with well-controlled type 2 diabetes mellitus: a case report. AB - BACKGROUND: Pyosalpinx, which is one of the pelvic inflammatory diseases, is usually observed in young women; it is rarely found in older women. Possible causative agents are thought to be Chlamydia trachomatis and Neisseria gonorrhea in addition to some Enterobacteriaceae. On the other hand, type 2 diabetes is a disease with a lot of complications such as hyperglycemia, inflammation, and immune disorders. Therefore, patients with type 2 diabetes mellitus have an increased susceptibility to infection especially when glycemic control is poor. CASE PRESENTATION: We experienced a rare case of large pyosalpinx in an elderly patient with well-controlled type 2 diabetes mellitus. A 72-year-old Japanese woman with a 10-year history of type 2 diabetes mellitus had symptoms of diarrhea and persistent pain in left lower abdomen. She had mild tenderness to palpation in her abdomen. Inflammation markers were markedly elevated. Her abdominal computed tomography and magnetic resonance imaging on admission revealed a tumor in left side of intrapelvis and we diagnosed her as having pyosalpinx. Pathogenic bacteria were not detected. On admission, her glycemic control was relatively good; in addition, her glycated hemoglobin levels were around 6% for over 1 year. Although pathogenic bacteria were not detected, we started antibiotics therapy. Fourteen days after starting the antibiotics her laboratory data were improved. Three months later, the tumor was markedly smaller compared to that on admission. CONCLUSIONS: We should keep in mind that older patients with type 2 diabetes mellitus are immunocompromised hosts and thereby they could have rare pelvic inflammatory disease such as pyosalpinx even when good glycemic control is obtained for a long period of time. PMID- 30290836 TI - Sequential MRI in pontine and extrapontine myelinolysis following rapid correction of hyponatremia. AB - OBJECTIVE: This study describes the MRI changes associated with pontine and extrapontine myelinolysis secondary to rapid correction of hyponatremia in dogs. The authors discuss the relevance of the results for theories of pathogenesis and for diagnosis of patients. RESULTS: MRI changes associated with pontine and extrapontine myelinolysis first occur on diffusion-weighted imaging. As a generalization, gadolinium enhancement, flair image change and T2 weighted image abnormality appear sequentially. PMID- 30290833 TI - Acidic microenvironment plays a key role in human melanoma progression through a sustained exosome mediated transfer of clinically relevant metastatic molecules. AB - BACKGROUND: Microenvironment cues involved in melanoma progression are largely unknown. Melanoma is highly influenced in its aggressive phenotype by the changes it determinates in its microenvironment, such as pH decrease, in turn influencing cancer cell invasiveness, progression and tissue remodelling through an abundant secretion of exosomes, dictating cancer strategy to the whole host. A role of exosomes in driving melanoma progression under microenvironmental acidity was never described. METHODS: We studied four differently staged human melanoma lines, reflecting melanoma progression, under microenvironmental acidic pHs pressure ranging between pH 6.0-6.7. To estimate exosome secretion as a function of tumor stage and environmental pH, we applied a technique to generate native fluorescent exosomes characterized by vesicles integrity, size, density, markers expression, and quantifiable by direct FACS analysis. Functional roles of exosomes were tested in migration and invasion tests. Then we performed a comparative proteomic analysis of acid versus control exosomes to elucidate a specific signature involved in melanoma progression. RESULTS: We found that metastatic melanoma secretes a higher exosome amount than primary melanoma, and that acidic pH increases exosome secretion when melanoma is in an intermediate stage, i.e. metastatic non-invasive. We were thus able to show that acidic pH influences the intercellular cross-talk mediated by exosomes. In fact when exposed to exosomes produced in an acidic medium, pH naive melanoma cells acquire migratory and invasive capacities likely due to transfer of metastatic exosomal proteins, favoring cell motility and angiogenesis. A Prognoscan-based meta analysis study of proteins enriched in acidic exosomes, identified 11 genes (HRAS, GANAB, CFL2, HSP90B1, HSP90AB1, GSN, HSPA1L, NRAS, HSPA5, TIMP3, HYOU1), significantly correlating with poor prognosis, whose high expression was in part confirmed in bioptic samples of lymph node metastases. CONCLUSIONS: A crucial step of melanoma progression does occur at melanoma intermediate -stage, when extracellular acidic pH induces an abundant release and intra-tumoral uptake of exosomes. Such exosomes are endowed with pro-invasive molecules of clinical relevance, which may provide a signature of melanoma advancement. PMID- 30290837 TI - Chemical crystal identification with deep learning machine vision. AB - OBJECTIVE: This study was carried out with the purpose of testing the ability of deep learning machine vision to identify microscopic objects and geometries found in chemical crystal structures. RESULTS: A database of 6994 images taken with a light microscope showing microscopic crystal details of selected chemical compounds along with 180 images of an unknown chemical was created to train and test, respectively the deep learning models. The models used were GoogLeNet (22 layers deep network) and VGG-16 (16 layers deep network), based on the Caffe framework (University of California, Berkeley, CA) of the DIGITS platform (NVIDIA Corporation, Santa Clara, CA). The two models were successfully trained with the images, having validation accuracy values of 97.38% and 99.65% respectively. Finally, both models were able to correctly identify the unknown chemical sample with a high probability score of 93.34% (GoogLeNet) and 99.41% (VGG-16). The positive results found in this study can be further applied to other unknown sample identification tasks using light microscopy coupled with deep learning machine vision. PMID- 30290840 TI - Development of a core outcome set (COS) and selecting outcome measurement instruments (OMIs) for non-valvular atrial fibrillation in traditional Chinese medicine clinical trials: study protocol. AB - BACKGROUND: An increasing number of clinical trials of traditional Chinese medicine are being conducted in the treatment of non-valvular atrial fibrillation (NVAF) in China. However, the heterogeneity of outcomes and outcome measurement instruments has produced little evidence for traditional Chinese medicine in treating NVAF because many trials cannot be included in a meta-analysis. The majority of the trials did not report endpoint outcomes, side effects or other important outcomes for patients, which makes it difficult to evaluate the efficacy and safety of traditional Chinese medicine. Therefore, it is important to develop a core outcome set (COS). Although there are two related COSs for clinical trials of atrial fibrillation, the methodology is limited, and the perspectives of Chinese experts and patients are unclear. Therefore, we will develop a COS and recommend outcome measurement instruments after finishing the COS, which can be used for clinical trials of traditional Chinese medicine in NVAF. METHODS/DESIGN: The method of the study will include eight stages led by a national multidisciplinary Steering Committee: (1) A systematic review will be developed to identify currently reported outcomes and traditional Chinese medicine syndromes in clinical trials of NVAF, (2) Semi-structured interviews of patients will be conducted to fill gaps in potential outcomes, (3) Traditional Chinese medicine syndrome names will be identified from medical records, (4) A dataset of traditional Chinese medicine syndrome names will be developed, (5) The investigation of traditional Chinese medicine syndromes will be conducted from cross-sectional study, (6) Two rounds of Delphi surveys will be carried out, (7) A consensus meeting will be conducted to develop a COS, and (8) Recommendations of outcome measurement instruments (OMIs), which should be used in the COS, will be developed. DISCUSSION: The COS will improve the consistency of outcome reporting and reduce the reporting bias in NVAF clinical trials of traditional Chinese medicine to improve the value of traditional Chinese medicine clinical trials. TRIAL REGISTRATION: This study is not a clinical trial, so it is registered in Core Outcome Measures in Effectiveness Trials Initiative (COMET). Registration number: 941 . Registered on 22 December 2016. PMID- 30290838 TI - ADAR1-mediated RNA-editing of 3'UTRs in breast cancer. AB - BACKGROUND: Whole transcriptome RNA variant analyses have shown that adenosine deaminases acting on RNA (ADAR) enzymes modify a large proportion of cellular RNAs, contributing to transcriptome diversity and cancer evolution. Despite the advances in the understanding of ADAR function in breast cancer, ADAR RNA editing functional consequences are not fully addressed. RESULTS: We characterized A to G(I) mRNA editing in 81 breast cell lines, showing increased editing at 3'UTR and exonic regions in breast cancer cells compared to immortalized non-malignant cell lines. In addition, tumors from the BRCA TCGA cohort show a 24% increase in editing over normal breast samples when looking at 571 well-characterized UTRs targeted by ADAR1. Basal-like subtype breast cancer patients with high level of ADAR1 mRNA expression shows a worse clinical outcome and increased editing in their 3'UTRs. Interestingly, editing was particularly increased in the 3'UTRs of ATM, GINS4 and POLH transcripts in tumors, which correlated with their mRNA expression. We confirmed the role of ADAR1 in this regulation using a shRNA in a breast cancer cell line (ZR-75-1). CONCLUSIONS: Altogether, these results revealed a significant association between the mRNA editing in genes related to cancer-relevant pathways and clinical outcomes, suggesting an important role of ADAR1 expression and function in breast cancer. PMID- 30290839 TI - Clinical significance in pediatric oncology randomized controlled treatment trials: a systematic review. AB - BACKGROUND: Clinical significance in a randomized controlled trial (RCT) can be determined using the minimal clinically important difference (MCID), which should inform the delta value used to determine sample size. The primary objective was to assess clinical significance in the pediatric oncology randomized controlled trial (RCT) treatment literature by evaluating: (1) the relationship between the treatment effect and the delta value as reported in the sample size calculation, and (2) the concordance between statistical and clinical significance. The secondary objective was to evaluate the reporting of methodological attributes related to clinical significance. METHODS: RCTs of pediatric cancer treatments, where a sample size calculation with a delta value was reported or could be calculated, were systematically reviewed. MEDLINE, EMBASE, and the Cochrane Childhood Cancer Group Specialized Register through CENTRAL were searched from inception to July 2016. RESULTS: RCTs (77 overall; 11 and 66), representing 95 (13 and 82) randomized questions were included for non-inferiority and superiority RCTs (herein, respectively). The minority (22.1% overall; 76.9 and 13.4%) of randomized questions reported conclusions based on clinical significance, and only 4.2% (15.4 and 2.4%) explicitly based the delta value on the MCID. Over half (67.4% overall; 92.3 and 63.4%) reported a confidence interval or standard error for the primary outcome experimental and control values and 12.6% (46.2 and 7.3%) reported the treatment effect, respectively. Of the 47 randomized questions in superiority trials that reported statistically non significant findings, 25.5% were possibly clinically significant. Of the 24 randomized questions in superiority trials that were statistically significant, only 8.3% were definitely clinically significant. CONCLUSIONS: A minority of RCTs in the pediatric oncology literature reported methodological attributes related to clinical significance and a notable portion of statistically insignificant studies were possibly clinically significance. PMID- 30290842 TI - Just how plain are plain tobacco packs: re-analysis of a systematic review using multilevel meta-analysis suggests lessons about the comparative benefits of synthesis methods. AB - BACKGROUND: Comparisons between narrative synthesis and meta-analysis as synthesis methods in systematic reviews are uncommon within the same systematic review. We re-analysed a systematic review on the effects of plain packaging of tobacco on attractiveness. We sought to compare different synthesis approaches within the same systematic review and shed light on the comparative benefits of each approach. METHODS: In our re-analysis, we included results relating to attractiveness in included reports. We extracted findings from studies and converted all estimates of differences in attractiveness to Cohen's d. We used multilevel meta-analysis to account for clustering of effect sizes within studies. RESULTS: Of the 19 studies reporting results on attractiveness, seven studies that included between-subjects analyses could be included in the meta analysis. Plain packs were less attractive than branded packs (d = - 0.59, 95% CI [- 0.71, - 0.47]), with negligible but uncertain between-studies heterogeneity (I2 = 0%, 95% CI [0.00, 70.81]) and high within-study heterogeneity (I2 = 92.6%, 95% CI [91.04, 93.90]). CONCLUSIONS: The meta-analysis found, similar to the narrative synthesis, that respondents typically rated plain packaging as less attractive than alternative (e.g. branded) tobacco packs. However, there were several trade-offs between analysis methods in the types and bodies of evidence each one contained and in the difference between partial precision and breadth of conclusions. Analysis methods were different in respect of the role of judgement and contextual variation and in terms of estimation and unexpected effect modification. In addition, we noted that analysis methods were different in how they accounted for heterogeneity and consistency. PMID- 30290841 TI - Evolutionary and developmental dynamics of sex-biased gene expression in common frogs with proto-Y chromosomes. AB - BACKGROUND: The patterns of gene expression on highly differentiated sex chromosomes differ drastically from those on autosomes, due to sex-specific patterns of selection and inheritance. As a result, X chromosomes are often enriched in female-biased genes (feminization) and Z chromosomes in male-biased genes (masculinization). However, it is not known how quickly sexualization of gene expression and transcriptional degeneration evolve after sex-chromosome formation. Furthermore, little is known about how sex-biased gene expression varies throughout development. RESULTS: We sample a population of common frogs (Rana temporaria) with limited sex-chromosome differentiation (proto-sex chromosome), leaky genetic sex determination evidenced by the occurrence of XX males, and delayed gonadal development, meaning that XY individuals may first develop ovaries before switching to testes. Using high-throughput RNA sequencing, we investigate the dynamics of gene expression throughout development, spanning from early embryo to froglet stages. Our results show that sex-biased expression affects different genes at different developmental stages and increases during development, reaching highest levels in XX female froglets. Additionally, sex biased gene expression depends on phenotypic, rather than genotypic sex, with similar expression in XX and XY males; correlates with gene evolutionary rates; and is not localized to the proto-sex chromosome nor near the candidate sex determining gene Dmrt1. CONCLUSIONS: The proto-sex chromosome of common frogs does not show evidence of sexualization of gene expression, nor evidence for a faster rate of evolution. This challenges the notion that sexually antagonistic genes play a central role in the initial stages of sex-chromosome evolution. PMID- 30290845 TI - Bougie-in-channel intubation technique. PMID- 30290843 TI - Modularity of genes involved in local adaptation to climate despite physical linkage. AB - BACKGROUND: Linkage among genes experiencing different selection pressures can make natural selection less efficient. Theory predicts that when local adaptation is driven by complex and non-covarying stresses, increased linkage is favored for alleles with similar pleiotropic effects, with increased recombination favored among alleles with contrasting pleiotropic effects. Here, we introduce a framework to test these predictions with a co-association network analysis, which clusters loci based on differing associations. We use this framework to study the genetic architecture of local adaptation to climate in lodgepole pine, Pinus contorta, based on associations with environments. RESULTS: We identify many clusters of candidate genes and SNPs associated with distinct environments, including aspects of aridity and freezing, and discover low recombination rates among some candidate genes in different clusters. Only a few genes contain SNPs with effects on more than one distinct aspect of climate. There is limited correspondence between co-association networks and gene regulatory networks. We further show how associations with environmental principal components can lead to misinterpretation. Finally, simulations illustrate both benefits and caveats of co-association networks. CONCLUSIONS: Our results support the prediction that different selection pressures favor the evolution of distinct groups of genes, each associating with a different aspect of climate. But our results went against the prediction that loci experiencing different sources of selection would have high recombination among them. These results give new insight into evolutionary debates about the extent of modularity, pleiotropy, and linkage in the evolution of genetic architectures. PMID- 30290844 TI - Anemia and other hematological profiles of pregnant women attending antenatal care in Debre Berhan Referral Hospital, North Shoa, Ethiopia. AB - OBJECTIVE: The aim of the study was to determine level of anemia and other hematological profiles in pregnant women attending antenatal care clinic in Debre Berhan Referral Hospital, Ethiopia. RESULTS: Prevalence of anemia was 2.8% and that of thrombocytopenia was 10.2%. Out of the anemic pregnant mothers, 5 (62.5%) were mildly anemic and 2 (25%) were severely anemic. The factor age < 20 years of mothers was significantly associated with anemia (P < 0.05). In addition, the occurrence of anemia in mothers who visited antenatal clinic two times is two times higher than those mother who visited the antenatal clinic three times. Moreover, the prevalence of anemia is two times more likely to occur in pregnant mothers who did not take iron supplements as compared to their counter parts. According to pregnancy periods; mean white blood cells count was (8.48 +/- 3.09, 8.83 +/- 2.73, 8.86 +/- 2.67) * 109/L for the first, second and third trimesters, respectively. Red blood cells and platelet counts in the first trimester were significantly higher than their corresponding values in third trimester (P < 0.01), whereas mean hemoglobin and hematocrit values were not statistically significant within trimesters (P > 0.05). PMID- 30290847 TI - Newcastle disease virus V protein inhibits apoptosis in DF-1 cells by downregulating TXNL1. AB - Many viral proteins are related to suppressing apoptosis in target cells and are hence beneficial to viral replication. The V protein of Newcastle disease virus (NDV) is one such protein that plays an important role in inhibiting apoptosis in a species-specific manner. However, to date, there have been no reports clarifying the antiapoptotic mechanisms of the V protein. The present study was undertaken to determine the apoptotic potential of the V protein in a chicken embryo fibroblast cell line (DF-1 cell) and to elucidate its molecular mechanisms of action. Here, a yeast two-hybrid system was used to screen the host proteins that interact with the V protein and identified thioredoxin-like protein 1 (TXNL1) as a potential binding partner. Immuno-colocalization of V protein and TXNL1 protein in DF-1 cells further verified the interaction of the two proteins. Through the overexpression of TXNL1 protein and knockdown of TXNL1 protein in DF 1 cells, the effects of NDV replication and cell apoptosis were examined. Cell apoptosis was detected by flow cytometry. The mRNA and protein expression levels of Bax, Bcl-2 and Caspase-3 were detected by quantitative real-time PCR (Q-PCR) and Western blotting. NDV expression was detected by Q-PCR and plaque assay. The results revealed that the TXNL1 protein induced apoptosis and inhibited NDV replication in DF-1 cells. Furthermore, the Western blot and Q-PCR results suggested that TXNL1 induced cell apoptosis through a pathway involving Bcl-2?Bax and Caspase-3. Finally, this work provides insight into the mechanism by which the V protein inhibits apoptosis. PMID- 30290846 TI - A conditional Pax6 depletion study with no morphological effect on the adult mouse corneal epithelium. AB - OBJECTIVE: The corneas of heterozygous Pax6+/- mice develop abnormally and deteriorate further after birth but it is not known whether the postnatal deterioration is predetermined by abnormal development. Our objective was to identify whether depletion of Pax6 in adult mice caused any corneal abnormalities, similar to those in Pax6+/- mice, where Pax6 levels are low throughout development and adulthood. We used two tamoxifen-inducible, Cre-loxP experimental strategies to deplete Pax6 either ubiquitously or in a restricted range of cell types. RESULTS: In a preliminary study, ubiquitous depletion of Pax6 by tamoxifen treatment of E9.5 CAG-CreERTg/-;Pax6fl/fl embryos affected eye development. Tamoxifen treatment of 12-week old, adult CAG-CreERTg/-;Pax6fl/+ and CAG-CreERTg/-;Pax6fl/fl mice resulted in weak and/or patchy Pax6 immunostaining in the corneal epithelium but caused no corneal abnormalities. GFP staining in tamoxifen-treated CAG-CreERTg/-;RCE:loxP reporter mice was also patchy. We attribute patchy Pax6 staining to mosaic deletion of the Pax6fl allele, probably caused by mosaic CAG-CreERTg expression. In a parallel study, we treated adult Krt19-CreERTg/-;Pax6fl/+ mice with tamoxifen to try to deplete Pax6 in limbal epithelial stem cells (LESCs) which replenish the corneal epithelium. However, Pax6 staining remained strong after a 12-week chase period so the Krt19-CreERTg/- transgene may have failed to target LESCs. PMID- 30290848 TI - High failure rate of proximal femoral locking plates in fixation of trochanteric fractures. AB - BACKGROUND: The aim of this study was to report our previous results of treatments for trochanteric fractures with proximal femoral locking plates (PFLP) and to analyze the underlying mechanisms and possible risk factors associated with the high failure rate of this technique. METHODS: From January 2010 to October 2014, 273 consecutive patients with trochanteric femoral fractures were identified, and 95 patients (with 97 fractures) ultimately met the inclusion criteria. Clinical records regarding demographic features and intraoperative data including total incision length, operation time, blood loss, and failures detected in radiographs were documented and assessed. The collected data were analyzed with SPSS 19.0 software. RESULTS: The stable group (AO/OTA 31 A1 and A2.1) had less blood loss than the unstable group (AO/OTA 31 A2.2, A2.3, and A3). The ultimate failure rate was 36% in 97 fractures. The obvious complications in this study included nonunion in 7 (7.2%) fractures, implant breakage in 4 (4.1%) fractures, varus deformity in 34 (35%) fractures, and loosening of the proximal femoral screw in 21 (21.6%) fractures. Six patients received reoperations. The total failure rate in the stable group was 17% and was 50% in the unstable group. In patients greater than 60 years old in the unstable group, the failure rate was 60.5%. CONCLUSIONS: High failure rates of PFLP were observed in patients with trochanteric fracture, especially in patients who were greater than 60 years old with unstable fracture types. PFLP was not an appropriate treatment for trochanteric fractures. PMID- 30290849 TI - Effect of machine learning methods on predicting NSCLC overall survival time based on Radiomics analysis. AB - BACKGROUND: To investigate the effect of machine learning methods on predicting the Overall Survival (OS) for non-small cell lung cancer based on radiomics features analysis. METHODS: A total of 339 radiomic features were extracted from the segmented tumor volumes of pretreatment computed tomography (CT) images. These radiomic features quantify the tumor phenotypic characteristics on the medical images using tumor shape and size, the intensity statistics and the textures. The performance of 5 feature selection methods and 8 machine learning methods were investigated for OS prediction. The predicted performance was evaluated with concordance index between predicted and true OS for the non-small cell lung cancer patients. The survival curves were evaluated by the Kaplan-Meier algorithm and compared by the log-rank tests. RESULTS: The gradient boosting linear models based on Cox's partial likelihood method using the concordance index feature selection method obtained the best performance (Concordance Index: 0.68, 95% Confidence Interval: 0.62~ 0.74). CONCLUSIONS: The preliminary results demonstrated that certain machine learning and radiomics analysis method could predict OS of non-small cell lung cancer accuracy.

PMID- 30290851 TI - Behavioral economics-based incentives supported by mobile technology on HIV knowledge and testing frequency among Latino/a men who have sex with men and transgender women: Protocol for a randomized pilot study to test intervention feasibility and acceptability. AB - BACKGROUND: Mobile Technology and Incentives (MOTIVES) is a randomized pilot study of a mobile technology-based and behavioral economics-supported HIV prevention intervention. Behavioral economics (BE) uses financial incentives in a way that departs from the traditional focus on large monetary payments. Instead, BE suggests that relatively small "nudges" can effectively initiate and sustain behavior change. This pilot study examines the feasibility and acceptability of an HIV prevention intervention that uses text messages in combination with BE incentives to improve retention of HIV prevention information and increase frequency of HIV testing among Latino/a men who have sex with men (MSM) and transgender women (TGW). The pilot will also estimate mission-critical design parameters with point and confidence interval estimates of the intervention to inform a future, fully powered effectiveness study. METHODS: The project will be conducted in collaboration with Bienestar Human Services, Inc. (Bienestar), a non profit community-based service organization. The intervention is being tested in a small, randomized controlled trial to pilot the intervention's feasibility and acceptability among 200 Latino/a MSM and TGW from Bienestar's HIV testing sites. Information on feasibility will include recruitment, refusal, and retention rates as well as message sending success rates; acceptability will include perceived appropriateness based on responses to the intervention. Participants will be randomized into either the "information only" control group (e.g. receiving text messages with HIV prevention information) or the "information plus" intervention group (e.g. additionally receiving quiz questions that provide the possibility of winning prizes). Participants will be followed for 12 months from enrollment. In addition to using data abstracted from Bienestar's routine data collection mechanisms, we will also collect survey data (blinded outcome assessment) from participants at 0, 6, and 12 months to provide an initial assessment of whether incentives affect their level of HIV knowledge and testing frequency. DISCUSSION: If shown to be acceptable, feasible, and resource-efficient, MOTIVES will provide an innovative way to communicate the latest HIV prevention information and support trimestral HIV screening among Latino/a MSM and TGW.

PMID- 30290854 TI - Ionic Liquids Applied to Extraction of Xenobiotics from Food, Environmental, and Biological Samples and for Analysis by Liquid Chromatography. AB - Ionic liquids (ILs) are a class of unique substances composed purely by cation and anions. Because of the unique properties of ILs (e.g., electric conductivity, low volatility, thermostability, and tenability), their use has attracted considerable interest, including an increasing number of publications on their use in analytical separation techniques. ILs applied as extraction solvents in liquid-liquid extraction methods and promote interactions between the analyte and solvent because of their unique chemical functional groups. In solid-phase extraction, ILs are usually used for the modification of stationary phases.

PMID- 30290852 TI - An early increase in endothelial protein C receptor is associated with excess mortality in pneumococcal pneumonia with septic shock in the ICU. AB - BACKGROUND: This study investigated changes in plasma level of soluble endothelial protein C receptor (sEPCR) in association with outcome in patients with septic shock. We explored sEPCR for early sepsis prognosis assessment and constructed a scoring system based on clinical and biological data, in order to discriminate between surviving at hospital discharge and non-surviving patients. METHODS: Clinical data and samples were extracted from the prospective "STREPTOGENE" cohort. We enrolled 278 patients, from 50 intensive care units (ICUs), with septic shock caused by pneumococcal pneumonia. Patients were divided into survivors (n = 194) and non-survivors (n = 84) based on in-hospital mortality. Soluble EPCR plasma levels were quantified at day 1 (D1) and day 2 (D2) by ELISA. The EPCR gene A3 haplotype was determined. Patients were followed up until hospital discharge. Univariate and multivariate analyses were performed. A scoring system was constructed using least absolute shrinkage and selection operator (lasso) logistic regression for selecting predictive variables. RESULTS: In-hospital mortality was 30.2% (n = 84). Plasma sEPCR level was significantly higher at D1 and D2 in non-surviving patients compared to patients surviving to hospital discharge (p = 0.0447 and 0.0047, respectively). Early increase in sEPCR at D2 was found in non-survivors while a decrease was observed in the survival group (p = 0.0268). EPCR A3 polymorphism was not associated with mortality. Baseline sEPCR level and its variation from D1 to D2 were independent predictors of in-hospital mortality. The scoring system including sEPCR predicted mortality with an AUC of 0.75. CONCLUSIONS: Our findings confirm that high plasma sEPCR and its increase at D2 are associated with poor outcome in sepsis and thus we propose sEPCR as a key player in the pathogenesis of sepsis and as a potential biomarker of sepsis outcome.

AB - Background: Dexpanthenol is a widely used humectant in hair care products, especially anti-hairfall products. The hair care industry is highly regulated in East Asia and treats products containing the combination of dexpanthenol, zinc pyrithione, and nicotinamide (vitamin B3) as quasi-drugs. Objective: Because dexpanthenol lacks a UV chromophore, existing methodologies for analysis in finished products include pretreatments and/or HPLC-UV analysis at low wavelengths at which poor signal-to-noise is observed. These time-consuming methods lack the robustness needed for routine use in quality laboratories. This has resulted in the need for a simple, fast, accurate, and robust UHPLC-MS method to quantify dexpanthenol in hair care products that could be easily adapted in quality laboratories. Methods: The MS detection was performed in positive ion mode with data acquired in single-ion recording for dexpanthenol (206.14 m/z), dexpanthenol-d6 (212.29 m/z), and Leucine Enkephalin acetate salt (556.28 m/z). Quantitation was performed using peak area ratio of dexpanthenol to the internal standard. Results: The resulting linear curve R2 was 0.9998 with sample precision RSDs <2.5%. The accuracy recoveries were within 2% and the robustness results were within 3% of the nominal conditions. Conclusions: The resulting method for the quantitation of dexpanthenol is fast, accurate, and robust in the range of 170.24-1024.5 ng/mL in shampoo and conditioner, which is easily adaptable in quality laboratories. Highlights: This study determined optimal sample preparation and UHPLC-MS conditions to quantify dexpanthenol in finished hair care products.

AB - Background: Pesticides are applied for pest control during the production of cereal grains used in beer production. Given the risks for consumers, it is important to analyze the pesticide residues. Objective: Quick, easy, cheap, effective, rugged, and safe (QuEChERS)-based methods are very effective, and improvement in the clean-up step is an important approach. Methods: Primary secondary amine (PSA) and magnesium silicate were evaluated for dispersive-solid phase extraction (d-SPE) clean-up step in extracts provided by the QuEChERS method in combination with GC-tandem MS for the determination of acetamiprid, terburfos, alachlor, ametryn, atrazine, azoxystrobin, carbofuran, carbosulfan, cypermethrin, deltamethrin, difenoconazole, esfenvalerate, flutriafol, thiamethoxam, and parathion-methyl in lager beer. Results: The amount of 50 mg of magnesium silicate was suitable for cleaning up beer extract as an alternative d SPE material to PSA. The method was validated using beer fortified with pesticides at three concentration levels (0.002, 0.01, and 0.1 MUg/mL). Average recoveries ranged from 70 to 123%, with RSDs between 0.3 and 10.5 %. Matrix effects were observed by comparing the slope of matrix-matched standard calibration with that of solvent. The method provided good linearity at the concentration levels of 0.001-2.5 MUg/mL. Detection limits ranged from 0.0001 to 0.0007 MUg/mL and quantification limits ranged from 0.001 to 0.006 MUg/mL. The method was applied to nine beer brands. Conclusions: Results showed that magnesium silicate is an efficient alternative clean-up material to reduce analysis costs while maintaining the method reliability and accuracy. Highlights: Magnesium silicate was effective as adsorbent for d-SPE step in the analysis of pesticides in beer.

AB - Long-term exposure of nitrifiers to high concentrations of free ammonia (FA) and free nitrous acid (FNA) may affect nitrifiers activity and nitrous oxide (N2O) emission. Two sequencing batch reactors (SBRs) were operated at influent ammonium nitrogen (NH4-N) concentrations of 800mg/L (SBRH) and 335mg/L (SBRL), respectively. The NH4-N removal rates in SBRH and SBRL were around 2.4 and 1.0g/L/day with the nitritation efficiencies of 99.3% and 95.7%, respectively. In the simulated SBR cycle, the N2O emission factors were 1.61% in SBRH and 2.30% in SBRL. N2O emission was affected slightly by FA with the emission factor of 0.22% 0.65%, while N2O emission increased with increasing FNA concentrations with the emission factor of 0.22%-0.96%. The dominant ammonia oxidizing bacteria (AOB) were Nitrosomonas spp. in both reactors, and their relative proportions were 38.89% in SBRH and 13.36% in SBRL. Within the AOB genus, a species (i.e., operational taxonomic unit [OTU] 76) that was phylogenetically identical to Nitrosomonas europaea accounted for 99.07% and 82.04% in SBRH and SBRL, respectively. Additionally, OTU 215, which was related to Nitrosomonas stercoris, accounted for 16.77% of the AOB in SBRL. PMID- 30290859 TI - Strong enhancement of methylene blue removal from binary wastewater by in-situ ferrite process. AB - Dye wastewater containing heavy metal ions is a common industrial effluent with complex physicochemical properties. The treatment of metal-dye binary wastewater is difficult. In this work, a novel in-situ ferrite process (IFP) was applied to treat Methylene Blue (MB)-Cu(II) binary wastewater, and the operational parameters were optimized for MB removal. Results showed that the optimum operating conditions were OH/M of 1.72, Cu2+/Fe2+ ratio of 1/2.5, reaction time of 90min, aeration intensity of 320mL/min, and reaction temperature of 40 degrees C. Moreover, the presence of Ca2+ and Mg2+ moderately influenced the MB removal. Physical characterization results indicated that the precipitates yielded in IFP presented high surface area (232.50m2/g) and a multi-porous structure. Based on the Langmuir model, the maximum adsorption capacity toward MB was 347.82mg/g for the precipitates produced in IFP, which outperformed most other adsorbents. Furthermore, IFP rapidly sequestered MB with removal efficiency 5 to 10 times greater than that by general ferrite adsorption, which suggested a strong enhancement of MB removal by IFP. The MB removal process by IFP showed two different high removal stages, each with a corresponding removal mechanism. In the first brief stage (<5min), the initial high MB removal (~95%) was achieved by predominantly electrostatic interactions. Then the sweep effect and encapsulation were dominant in the second longer stage. PMID- 30290860 TI - The effects of hydrogen peroxide pre-oxidation on ultrafiltration membrane biofouling alleviation in drinking water treatment. AB - Pre-oxidation is widely used to reduce ultrafiltration membrane fouling. However, the variation in the composition of microbial communities and extracellular polymeric substances (EPSs) accompanying pre-oxidation in drinking water treatment has received little attention. In this study, hydrogen peroxide (H2O2) was used in a coagulation-ultrafiltration process with Al2(SO4)3.18H2O. A long term reactor experiment (60d) showed that pre-oxidation alleviated membrane fouling, mainly due to its inhibition of microbial growth, as observed by flow cytometry measurements of the membrane tank water. Further analysis of the formed cake layer demonstrated that the corresponding levels of EPS released from the microbes were lower with than without H2O2 treatment. In comparison to polysaccharides, proteins dominated the EPS. 2D-electrophoresis showed little difference (p>0.05, Student's t-test) in the composition of proteins in the cake layer between the treatments with and without H2O2. The molecular weights of proteins ranged from approximately 30-50kDa and the majority of isoelectric points ranged from 6 to 8. High-throughput sequencing showed that the predominant bacteria were Proteobacteria, Bacteroidetes, and Verrucomicrobia in both cake layers. However, the relative abundance of Planctomycetes was higher in the cake layer with H2O2 pre-oxidation, which was likely probably due to the strong oxidative resistance of its cell wall. Overall, our findings clarify the fundamental molecular mechanism in H2O2 pre-oxidation for ultrafiltration membrane bio-fouling alleviation in drinking water treatment. PMID- 30290861 TI - Influence of metal-contamination on distribution in subcellular fractions of the earthworm (Metaphire californica) from Hunan Province, China. AB - Earthworms have the ability to accumulate of heavy metals, however, there was few studies that addressed the metals in earthworm at subcellular levels in fields. The distributions of metals (Cd, Cu, Zn, and Pb) in subcellular fractions (cytosol, debris, and granules) of earthworm Metaphire californica were investigated. The relationship between soil metals and earthworms were analyzed to explain its high plasticity to inhabit in situ contaminated soil of Hunan Province, south China. The concentration of Cd in subcellular compartments showed the same pattern as Cu in the order of cytosol > debris > granules. The distribution of Zn and Pb in earthworms indicated a similar propensity for different subcellular fractions that ranked as granules > debris > cytosol for Zn, and granules > cytosol > debris for Pb. The internal metal concentrations in earthworms increased with the soil metals (p<0.05). Significant positive correlations were found between soil Cd and Cd concentrations in cytosol and debris (p<0.01). Moreover, the soil Pb concentration significantly influenced the Pb concentrations in cytosol and debris (p<0.01), similar to that of Cd. The soil Cu concentrations was only associated with the Cu in granules (p<0.05). Soil Zn concentrations correlated with the Zn concentrations in each subcellular fraction (p<0.05). Our results provide insights into the variations of metals partitioning in earthworms at subcellular levels and the relationships of soil metals, which could be one of the detoxification strategies to adapt the long-term contaminated environment. PMID- 30290862 TI - Enhanced photocatalytic activity of rGO/TiO2 for the decomposition of formaldehyde under visible light irradiation. AB - Due to the low concentration of indoor air contaminants, photocatalytic technology shows low efficiency for indoor air purification. The application of TiO2 for photocatalytic removal of formaldehyde is limited, because TiO2 can only absorb ultraviolet (UV) light. Immobilization of TiO2 nanoparticles on the surface of graphene can improve the visible light photocatalytic activity and the adsorption capacity. In this study, rGO (reduced graphene oxide)/TiO2 was synthesized through a hydrothermal method using titanium tetrabutoxide and graphene oxide as precursors, and was used for the degradation of low concentration formaldehyde in indoor air under visible light illumination. Characterization of the crystalline structure and morphology of rGO/TiO2 revealed that most GO was reduced to rGO during the hydrothermal treatment, and anatase TiO2 nanoparticles (with particle size of 15-30nm) were dispersed well on the surface of the rGO sheets. rGO/TiO2 exhibited excellent photocatalytic activity for degradation of formaldehyde in indoor air and this can be attributed to the role of rGO, which can act as the electron sink and transporter for separating photo-generated electron-hole pairs through interfacial charge transfer. Furthermore, rGO could adsorb formaldehyde molecules from air to produce a high concentration of formaldehyde on the surface of rGO/TiO2. Under visible light irradiation for 240min, the concentration of formaldehyde could be reduced to 58.5ppbV. rGO/TiO2 showed excellent moisture-resistance behavior, and after five cycles, rGO/TiO2 maintained high photocatalytic activity for the removal of formaldehyde (84.6%). This work suggests that the synthesized rGO/TiO2 is a promising photocatalyst for indoor formaldehyde removal.

AB - Tourism can form an important component of a nation's GDP, and Vietnam is among the most visited countries in Southeast Asia. Most studies on personal exposure focus on the general population, or occupational cohorts with exposure to specific pollutants. However, short-term exposure to air pollutants while visiting regions with high levels of air pollution can lead to acute health effects. A personal exposure study was conducted across three cities in Vietnam to estimate exposure to particulate matter (PM2.5) and black carbon for tourists. Measurements were conducted during the wet season in 2014 in Ho Chi Minh City, Da Lat and Nha Trang using portable instrumentation. Average 24-hr PM2.5 and BC exposures were estimated as 18.9+/-9.24 and 3.41+/-1.33MUg/m3 and among the three cities, Ho Chi Minh was found to have the highest PM2.5 concentrations. Environmental tobacco smoke, commuting and street food stands were found to contribute to highest levels of exposure to PM2.5 and BC across all cities.

AB - The effect of K deactivation on V2O5/WO3-TiO2 and Ce-doped V2O5/WO3-TiO2 catalysts in the selective catalytic reduction (SCR) of NOx by NH3 was studied. Ce-doped V2O5/WO3-TiO2 showed significantly higher resistance to K deactivation than V2O5/WO3-TiO2. Ce-doped V2O5/WO3-TiO2 with K/V=4 (molar ratio) showed 90% NOx conversion at 350 degrees C, whereas in this case V2O5/WO3-TiO2 showed no activity. The fresh and K-poisoned V2O5/WO3-TiO2 and Ce-doped V2O5/WO3-TiO2 catalysts were investigated by means of in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), NH3-temperature progress decomposition (NH3-TPD), X-ray photoelectron spectroscopy (XPS) and H2-temperature program reduction (H2-TPR). The effect of Ce doping on the improving resistance to K of V2O5/WO3-TiO2were discussed. PMID- 30290865 TI - Effect of biochar on fate and transport of manure-borne estrogens in sandy soil. AB - The feasibility of using two types of biochars to reduce steroid hormone pollution from poultry and swine manure application on agricultural land was evaluated. The sorption affinity and desorption resistance of softwood and hardwood biochars were also determined for two estrogen hormones, 17beta estradiol (E2) and its primary metabolite estrone (E1). The softwood and hardwood biochars demonstrated high retention capacity for both estrogens. The effective distribution coefficient (Kdeff) of soil-softwood-derived biochar (SBS450) was significantly higher than soil-hardwood-derived biochar (SBH750), indicating the stronger sorption affinity of SBS450 for estrogens. To validate the laboratory results, a field lysimeter experiment was conducted to study the fate and transport of E2 and E1 in soil and leachate in the presence of 1% softwood biochar (BS450) in topsoil and to compare it with soil without any amendments. The spatio-temporal distribution of both estrogens was monitored at four depths over a 46-day period. The lysimeters, in which the surface layer of soil was amended with biochar, retained significantly higher concentrations of both estrogen hormones. Although they leached through the soil and were detected in leachates, collected at 1.0m depth, the concentrations were significantly lower in the leachate collected from biochar-amended lysimeters. The result confirmed the efficacy of biochar amendment as a remediation technique to alleviate the manure-borne hormonal pollution of groundwater. PMID- 30290866 TI - High mercury leachate containing HgS22- complex ion: Detoxifying solidification and high efficiency Hg extraction. AB - Clean and efficient treatment of high-mercury leachate produced from remediation of mercury-polluted soil has become a huge challenge for environmental scientists. In this work, cement solidification was firstly adopted to treat the high-concentration mercury leachate, which had high alkalinity. Different mercury concentrations, namely 3.120mg/L Hg mercury leachate and 9.243mg/L Hg mercury concentrated leachate, were separately solidified by Portland cement. The results indicated that simply using the cement can properly solidify both the leachates to meet the waste landfill standard, with liquid (mL)/solid (g) ratio (L/S ratio) of 4:10-6:10. In order to make full use of mercury in the leachates, a Hg extraction method was subsequently carried out under different experimental parameters, such as temperature and pH value. It was shown that the Hg extraction ratio could reach as high as 99.84% and almost all the mercury in the leachate could be transformed to HgS precipitate; moreover, the Hg concentration in the treated leachate was reduced from 3.120 to 0.005mg/L at pH2.98 and 30 degrees C, which was much less than the limit of the national standard, indicating that the leachate had been completely cleaned and could be discharged freely. Hence, simple cement solidification renders high-mercury leachate nontoxic, and the Hg extraction method can successfully recover the Hg and enable the residual leachate to be discharged safely. PMID- 30290867 TI - Facile one-step synthesis of functionalized biochar from sustainable prolifera green-tide source for enhanced adsorption of copper ions. AB - The use of biochars formed by hydrothermal carbonization for the treatment of contaminated water has been greatly limited, due to their poorly developed porosity and low content of surface functional groups. Also, the most common modification routes inevitably require post-treatment processes, which are time consuming and energy-wasting. Hence, the objective of this research was to produce a cost-effective biochar with improved performance for the treatment of heavy metal pollution through a facile one-step hydrothermal carbonization process coupled with ammonium phosphate, thiocarbamide, ammonium chloride or urea, without any post-treatment. The effects of various operational parameters, including type of modification reagent, time and temperature of hydrothermal treatment, and ratio of modification reagent to precursor during impregnation, on the copper ion adsorption were examined. The adsorption data fit the Langmuir adsorption isotherm model quite well. The maximum adsorption capacities (mg/g) of the biochars towards copper ions followed the order of 40-8h-1.0-APBC (95.24)>140 8h-0-BC (12.52)>140-8h-1.0-TUBC (12.08)>140-8h-1.0-ACBC (7.440)>140-8h-1.0-URBC (5.277). The results indicated that biochars modified with ammonium phosphate displayed excellent adsorption performance toward copper ions, which was 7.6-fold higher than that of the pristine biochar. EDX and FT-IR analyses before and after adsorption demonstrated that the main removal mechanism involved complexation between the phosphate groups on the surface of the modified biochars and copper ions. PMID- 30290868 TI - Study of ciprofloxacin removal by biochar obtained from used tea leaves. AB - In this study, used tea leaves (UTLs) were pyrolyzed to obtain used tea-leaf biochar (UTC), and then the UTC was used as an adsorbent to remove ciprofloxacin (CIP) from aqueous solutions. Batch experiments were conducted to investigate the CIP adsorption performance and mechanism. The results showed that the CIP adsorbing ability first increased and then declined as the UTC pyrolysis temperature increased. The UTC obtained at 450 degrees C presented excellent CIP absorbing ability at pH6 and 40 degrees C. The maximum monolayer adsorption capacity was 238.10mg/g based on the Langmuir isotherm model. The pseudo-second order kinetic equation agreed well with the CIP adsorption process, which was controlled by both external boundary layer diffusion and intra-particle diffusion. The characterization analysis revealed that the OH groups, CC bonds of aromatic rings, CH groups in aromatic rings and phenolic CO bonds play vital roles in the CIP adsorption process, and that the NC, NO, OCO and COH groups of UTC were consumed in large quantities. pi-pi interactions, hydrogen bonding and electrostatic attraction are inferred as the main adsorption mechanisms. The present work provides not only a feasible and promising approach for UTLs utilization but also a potential adsorbent material for removing high concentrations of CIP from aqueous solutions. PMID- 30290869 TI - Oxidation of antimony (III) in soil by manganese (IV) oxide using X-ray absorption fine structure. AB - The oxidation of antimony (III) in soils was studied using X-ray absorption fine structure (XAFS) spectra. An andosol soil sample and artificial soil samples (SiO2 blended with iron (III) hydroxide and manganese (IV) oxide) were used herein. After adding antimony (III) oxide to all soil samples, the oxidation process was observed by recording the XAFS spectra of Sb K-edge, Fe K-edge, and Mn K-edge. The results indicated that manganese (IV) oxide played an important role in the oxidation of Sb(III); however iron (III) hydroxide was not directly related to the reaction. During a 2-hr continuous Sb K-edge X-ray absorption near edge structure (XANES) measurement with an interval of 1min of one of the artificial soil samples (SiO2+MnO2+Sb2O3), a pseudo-first-order reaction was determined with an average estimated rate of 0.52+/-0.04hr-1. Compared to the lower oxidation rate of andosol, it is suggested that because of the low concentration of Mn(IV) in natural soils, the oxidation process of Sb(III) might be relatively slow and require more time to convert Sb(III) to Sb(V). PMID- 30290870 TI - Effects of O3/Cl2 disinfection on corrosion and opportunistic pathogens growth in drinking water distribution systems. AB - The effects of O3/Cl2 disinfection on corrosion and the growth of opportunistic pathogens in drinking water distribution systems were studied using annular reactors (ARs). The corrosion process and most probable number (MPN) analysis indicated that the higher content of iron-oxidizing bacteria and iron-reducing bacteria in biofilms of the AR treated with O3/Cl2 induced higher Fe3O4 formation in corrosion scales. These corrosion scales became more stable than the ones that formed in the AR treated with Cl2 alone. O3/Cl2 disinfection inhibited corrosion and iron release efficiently by changing the content of corrosion-related bacteria. Moreover, ozone disinfection inactivated or damaged the opportunistic pathogens due to its strong oxidizing properties. The damaged bacteria resulting from initial ozone treatment were inactivated by the subsequent chlorine disinfection. Compared with the AR treated with Cl2 alone, the opportunistic pathogens M. avium and L. pneumophila were not detectable in effluents of the AR treated with O3/Cl2, and decreased to (4.60+/-0.14) and (3.09+/-0.12) log10 (gene copies/g corrosion scales) in biofilms, respectively. The amoeba counts were also lower in the AR treated with O3/Cl2. Therefore, O3/Cl2 disinfection can effectively control opportunistic pathogens in effluents and biofilms of an AR used as a model for a drinking water distribution system. PMID- 30290871 TI - A green method to synthesize flowerlike Fe(OH)3 microspheres for enhanced adsorption performance toward organic and heavy metal pollutants. AB - Dyestuffs and heavy metal ions in water are seriously harmful to the ecological environment and human health. Three-dimensional (3D) flowerlike Fe(OH)3 microspheres were synthesized through a green yet low-cost injection method, for the removal of organic dyes and heavy metal ions. The Fe(OH)3 microspheres were characterized by thermal gravimetric analysis (TGA), Fourier transform infrared (FT-IR), and transmission electron microscopy (TEM) techniques. The adsorption kinetics of Congo Red (CR) on Fe(OH)3 microspheres obeyed the pseudo-second-order model. Cr6+ and Pb2+ adsorption behaviors on Fe(OH)3 microspheres followed the Langmuir isotherm model. The maximum adsorption capacities of the synthesized Fe(OH)3 were 308, 52.94, and 75.64mg/g for CR, Cr6+, and Pb2+ respectively. The enhanced adsorption performance originated from its surface properties and large specific surface area of 250m2/g. The microspheres also have excellent adsorption stability and recyclability. Another merit of the Fe(OH)3 material is that it also acts as a Fenton-like catalyst. These twin functionalities (both as adsorbent and Fenton-like catalyst) give the synthesized Fe(OH)3 microspheres great potential in the field of water treatment. PMID- 30290872 TI - Effect of lanthanum loading on nanosized CeO2-ZnO solid catalysts supported on cordierite for diesel soot oxidation. AB - We report the application of a solid lanthanum-ceria-zinc catalyst in the catalytic regeneration of diesel particulate filters (DPF) in diesel engines. We synthesized a CeO2-ZnO-La2O3 (Ce-Zn-La) mixed oxide by a lactic acid-mediated sol gel method, which efficiently coated cordierite substrates for soot capture and combustion. We studied the effects of La loading on the physicochemical and catalytic properties of Ce-Zn mixed oxide during low-temperature soot combustion processes. We characterized the synthesized catalysts by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), N2 adsorption, Raman spectroscopy, oxygen storage capacity (OSC), and scanning and transmission electron microscopy (SEM and TEM). Thermogravimetric and differential thermal analysis (TGA/DTA) confirmed that the catalysts effectively reduced the soot oxidation temperature. The ternary Ce-Zn-La mixed oxide catalyst with Ce/Zn/La atomic ratio of 2:1:0.5 had the highest catalytic activity and promoted soot oxidation at temperatures below 390 degrees C. This indicated that the large number of oxygen vacancies in the catalyst structure generated oxygen species at low temperatures. Raman spectroscopy measurements revealed the presence of oxygen vacancies and lattice defects in Ce-Zn-La samples, which were key parameters concerning the stability and redox properties of the prepared catalysts. PMID- 30290873 TI - Size-resolved effective density of submicron particles during summertime in the rural atmosphere of Beijing, China. AB - Particle density is an important physical property of atmospheric particles. The information on high time-resolution size-resolved particle density is essential for understanding the atmospheric physical and chemical aging processes of aerosols particles. In the present study, a centrifugal particle mass analyzer (CPMA) combined with a differential mobility analyzer (DMA) was deployed to determine the size-resolved effective density of 50 to 350nm particles at a rural site of Beijing during summer 2016. The measured particle effective densities decreased with increasing particle sizes and ranged from 1.43 to 1.55g/cm3, on average. The effective particle density distributions were dominated by a mode peaked at around 1.5g/cm3 for 50 to 350nm particles. Extra modes with peaks at 1.0, 0.8, and 0.6g/cm3 for 150, 240, and 350nm particles, which might be freshly emitted soot particles, were observed during intensive primary emissions episodes. The particle effective densities showed a diurnal variation pattern, with higher values during daytime. A case study showed that the effective density of Aitken mode particles during the new particle formation (NPF) event decreased considerably, indicating the significant contribution of organics to new particle growth. PMID- 30290874 TI - Toxicity assessment and histopathological analysis of nano-ZnO against marine fish (Mugilogobius chulae) embryos. AB - The toxicity of nano-materials has received increasing attention in recent years. Nevertheless, relatively few studies have focused on their oceanic distributions and toxicities. In this study, we assessed nano-ZnO toxicity in marine organisms using the yellowstriped goby (Mugilogobius chulae). The relative differences in nano-ZnO dissolution and dispersal in seawater and fresh water were also investigated. The effects of nano-ZnO on embryonic development, deformity, hatching, mortality, and histopathology were analyzed. In addition, the effects of the Zn2+ concentration on M. chulae hatching and mortality were compared. The results showed that nano-ZnO had higher solubility in seawater than in fresh water. Nano-ZnO significantly inhibited hatching. By the fifth day of exposure, the LC50 of nano-ZnO was 45.40mg/L, and the mortality rate spiked. Hatching inhibition and lethality were dose-dependent over a range of 1-25mg/L nano-ZnO. Zn2+ inhibited hatching and increased lethality, but its effects were weaker than those of nano-ZnO at the same concentrations. Nano-ZnO also induced spinal bending, oedema, hypoplasia, and other deformities in M. chulae embryos and larvae. Histopathology revealed vacuolar degeneration, hepatocyte and enterocyte enlargement, and morphological abnormalities of the vertebrae. Therefore, nano ZnO caused malformations in M. chulae by affecting embryonic growth and development. We conclude that nano-ZnO toxicity in seawater was significantly positively correlated with the associated Zn2+ concentration and sedimentary behaviour. The toxicity of nano-ZnO was cumulative and showed a critical point, beyond which embryonic and developmental toxicity in marine fish was observed.

AB - Sulfonamides are used in human therapy, animal husbandry and agriculture but are not easily biodegradable, and are often detected in surface water. Sulfamethazine (SMZ) and sulfadiazine (SDZ) are two widely used sulfonamide antibiotics that are used heavily in agriculture. In this study, they were degraded in an aqueous system by chlorination after pre-oxidation with ferrate(VI) (FeVIO42-, Fe(VI)), an environmentally friendly oxidation technique that has been shown to be effective in degrading various organics. The kinetics of the degradation were determined as a function of Fe(VI) (0-1.5mg/L), free chlorine (0-1.8mg/L) and temperature (15-35 degrees C). According to the experimental results, SMZ chlorination followed second-order kinetics with increasing Fe(VI) dosage, and the effect of the initial free chlorine concentration on the reaction kinetics with pre-oxidation by Fe(VI) fitted a pseudo-first order model. The rate constants of SDZ and SMZ chlorination at different temperatures were related to the Arrhenius equation. Fe(VI) could reduce the levels of THMs formed and the toxicity of the sulfonamide degradation systems with Fe(VI) doses of 0.5-1.5mg/L, which provides a reference for ensuring water quality in drinking water systems.

Therefore, eight water-lifting aerators (WLAs) were installed in this reservoir, which could overcome thermal stratification and increase oxygenation with gas flows between 20 and 50m3/hr, and oxygenate the hypolimnion with gas flows less than 20m3/hr. To examine the destratification efficiency of the WLA system, we used a three-dimensional hydrodynamic module based on MIKE 3 to simulate the thermal structure of Heihe Reservoir and compared the simulations with measured data. Results showed that operation of the WLA system promoted water mixing and effectively oxygenated the hypolimnion. Through the established energy utilization assessment method, the energy utilization efficiency of the WLA system was between 5.36% and 7.30%, indicating the capability of the technique for destratification in such a large reservoir. When the surface water temperature dropped to the theoretical mixed water temperature calculated by the energy utilization assessment method, reducing gas flow could save energy. This would prevent anaerobic conditions from occurring in the bottom water and maintain good water quality in Heihe Reservoir.

PMID- 30290877 TI - Reduced graphene oxide-nano zero value iron (rGO-nZVI) micro-electrolysis accelerating Cr(VI) removal in aquifer. AB - Nanoscale zero-valent iron (nZVI) assembled on graphene oxide (GO) (rGO-nZVI) composites were synthesized by reduction of GO and ferrous ions with potassium borohydride, for use in Cr(VI) removal from aqueous solution. The results showed that the two-dimensional structure of GO could provide a skeleton support for Fe0, thus overcoming the bottleneck of aggregation for nZVI. Also, rGO-nZVI would form a ferric-carbon micro-electrolysis system in Cr(VI)-contaminated aquifers, enhancing and accelerating electron transfer, exhibiting high rate and capacity for Cr(VI) removal. The optimum dosage of the applied rGO-nZVI was linearly correlated with the initial Cr(VI) concentration. Characterization of rGO-nZVI before and after reaction with Cr(VI) revealed the process of Cr(VI) removal: rGO nZVI firstly transferred electrons from Fe0 cores via their Fe(II)/Fe(III) shells to the GO sheet; there, negatively charged Cr(VI) received electrons and changed into positively charged Cr(III), which was adsorbed by the negatively charged GO sheet, avoiding the capping and passivating of nZVI. rGO-nZVI formed a good electrically conductive network, and thus had long-term electron releasing properties, which was important for groundwater remediation.

PMID- 30290881 TI - Prevalence and Prognostic Significance of Right Ventricular Dysfunction in Patients With Hypertrophic Cardiomyopathy. AB - Few data are available regarding the prevalence and clinical significance of right ventricular systolic dysfunction (RVSD) in hypertrophic cardiomyopathy (HC) patients. This study aimed to evaluate right ventricular (RV) systolic function by cardiovascular magnetic resonance and explore the prevalence and prognostic significance of RVSD in HC patients. A total of 226 patients with HC assessed by cardiovascular magnetic resonance were included in this retrospective study. RVSD was defined by RV ejection fraction (RVEF) <=45% and was present in 26 (11.5%) patients. Association between RVSD, clinical characteristics, and outcomes were analyzed. RVEF was significantly lower in patients with RVSD than without RVSD (36.2 +/- 7.0% vs 60.5 +/- 7.4%, p < 0.001). There was a positive correlation between RVEF and left ventricular ejection fraction (r = 0.45; p < 0.001). During a mean follow-up of 30.5 +/- 23.9 months, there were 22 (9.7 %) all-cause mortality, including 12 (5.3%) cardiovascular death. Kaplan-Meier analysis showed a significantly higher risk for cardiovascular mortality in patients with RVSD (p = 0.026), but no significant difference in all-cause mortality (p = 0.118) and heart failure related rehospitalization (p = 0.485). On multivariate Cox regression analysis, RVSD (hazard ratio 5.36; confidence interval 1.39 to 20.77; p = 0.015) and RVEF (hazard ratio 0.94; confidence interval 0.89 to 0.98; p = 0.011) were independent predictors of cardiovascular mortality. In conclusion, RVSD is a common phenotype and a strong independent predictor of cardiovascular mortality in HC patients. PMID- 30290883 TI - Calcitriol increases nitric oxide production and modulates microbicidal capacity against Mycobacterium bovis in bovine macrophages. AB - Bovine tuberculosis, a re-emerging infectious disease caused by Mycobacterium bovis, can be transmitted to humans. Global prevalence of M. bovis in humans is underestimated and represents a serious public health risk in developing countries. In light of this situation, it is important to note that our understanding of the immunopathogenesis of human tuberculosis can be improved by studying this disease in the bovine model. Stimulation of the bovine innate immune system with calcitriol (1,25(OH)2D3) leads to an increase in bactericidal molecules involved in macrophage antimicrobial activity. It is unknown, however, if calcitriol's effect on bovine macrophages impacts intracellular bacterial replication. With these considerations in mind, this study sought to investigate the specific role of calcitriol in tuberculosis control in bovine macrophages, in the hopes of uncovering information applicable to human tuberculosis. As such, infection with M. bovis was shown to induce expression of CYP27B1 and VDR genes in macrophages. Moreover, addition of 1,25(OH)2D3 to cultures of macrophages previously infected with mycobacteria and/or activated by LPS triggered cellular expression of nitric oxide synthase (NOS2) and increased nitrite concentrations, both indicators of nitric oxide (NO) production. By means of a microbicidal assay, addition of 1,25(OH)2D3 was seen to increase macrophage phagocytosis and to decrease mycobacterial intracellular replication. Thus, taken together, our results show that calcitriol can help stimulate the innate immune system of bovines by increasing phagocytosis and decreasing intracellular replication of microorganisms, such as M. bovis, in macrophages, through the VDR pathway. PMID- 30290882 TI - Comparison of a new in-house HIV-1 TaqMan real-time PCR and three commercial HIV 1 RNA quantitative assays. AB - OBJECTIVES: The aim of this study was to compare the analytical performance of an In-House HIV-1 viral load determination technique with three commercial kits including COBAS(r) AmpliPrep, RealStar(r), and RTA(r) HIV-1 Real-Time PCR. RESULTS: A total of 100 HIV-1 suspicious plasma samples were tested by the In House TaqMan(r) Real-Time PCR assay along with the above-mentioned kits. Comparative analysis between In-House and reference method (COBAS(r) AmpliPrep/COBAS(r) TaqMan(r) HIV-1 Test version 2.0) showed high concordance with a mean difference of 0.08 log10 copies/ml. All samples results were within -0.16 0.31 log10 copies/ml. A suitable correlation was obtained with a coefficient (R2) of 0.82 between the In-House assay and RTA(r) Kit, however, two positive samples were not detected. The lowest agreement was detected with RealStar(r) HIV Kit 1.0 (R2 = 0.49, r = 0.7). CONCLUSIONS: The newly developed method has suitable sensitivity, accuracy, and precision. In addition, it is cost-effective and can be an alternative in all laboratories. PMID- 30290884 TI - Fine mapping epitope on glycoprotein-Gn from Crimean-Congo hemorrhagic fever virus. AB - Glycoprotein (GP) is a major antigen of Crimean-Congo hemorrhagic fever virus (CCHFV), and binds to its receptor on the host cell and induces protective immunity in the host. The aim of this study is to identify all linear B cell epitopes (BCEs) on the N-terminal glycoprotein (Gn) of CCHFV using a modified overlapping peptide biosynthesis method. The eight fine BCEs (Gn-E1a, 543RTQLV547; E1b, 553EIH555; E1c, 554IHEDSY559; E1d, 557DSYG560; E2, 615CKQGFC620; E3a, 657GDILVD662; E3b, 662DCSGGQQH669, and E4, 678LGCPNVPL685) were identified using the rabbit antisera, which all were recognized by serum from IgG-positive sheep CCHFV-infected naturally in Western blotting. The multiple sequence alignment (MSA) revealed high conservation of the identified BCEs among ten CCHFV strains from different areas. These mapped epitopes of the CCHFV Gn would provide a basis for further the elucidation of CCHFV pathogenesis, and the development of CCHFV multi-epitope vaccines and detection reagents.

AB - Toxoplasma gondii is an obligate intracellular parasitic protozoan that infects a wide variety of vertebrates as intermediate hosts. The aim of the current systematic review study is to clarify the latest status of studies in the literature regarding rhoptry-associated recombinant proteins or rhoptry associated recombinant DNAs as potential vaccines against toxoplasmosis. The search was performed systematically in 8 databases, four in English and four in Persian, up to February 2017. Overall, ROP2 was the most commonly used ROPs in DNA vaccines (27.27%) and protein vaccines (6.81%). Furthermore, regarding the type of adjuvants, route and dose of vaccination, animal models, challenge methods, and measurement of immune responses has been discussed in the text. It is hoped that this article help researchers to conduct more effective studies in the field of immunization against T. gondii. PMID- 30290886 TI - Clostridioides difficile in the environment, food, animals and humans in southern Italy: Occurrence and genetic relatedness. AB - One hundred and thirty-eight C. difficile isolates from different sources (66 from the environment, 36 from animals, 9 from food and 27 from humans) were ribotyped by capillary electrophoresis PCR ribotyping (CE-PCR). A multilocus variable tandem repeat analysis (MLVA) was carried out on a sample subset. The most frequently isolated PCR ribotypes were 126 (15.9%), 078 (14.5%), 011/018 (11.6%), 014/020/077 (10.1%), and 010 (2.8%). In particular, strains of PCR ribotype 011/018 were isolated from human, raw milk and environmental samples. The hypervirulent PCR ribotype 027 was isolated from two human samples. The majority of the strains were toxigenic (34.1% showed the toxigenic profile A+B+CDT+ and 38.9% the profile A+B+CDT-). MLVA allowed to identify 4 clonal complexes of genetically related isolates: complex n. 1 grouped together human, environmental and food strains, whereas complex n. 3 included human and environmental isolates. The use of MLVA gave further evidence to the possible role of environment, animals and food as routes of transmission of C. difficile infections to human. PMID- 30290887 TI - Genetic diversity and prevalence of piroplasm species in equids from Turkey. AB - Equine piroplasmosis (EP) is a protozoon disease caused by Babesia caballi and Theileria equi transmitted by ticks from the Ixodidae family. This study investigated the genetic heterogeneity and diversity of piroplasm genotypes using the Reverse Line Blotting (RLB) technique for piroplasm species in equids in Turkey. A total of 233 blood samples from 142 horses and 91 donkeys were collected in Sanliurfa, Tunceli, and Igdir. The RLB assay was performed for simultaneous detection of piroplasm species. The prevalence of piroplasm infection was 33.5% (95% CI; 27.4-39.9). T. equi was the most common species (%20.2; 95% CI 15.2-25.9), whereas B. caballi infection was not detected. Nine samples hybridized to the Theileria/Babesia and Theileria catch-all probes but did not hybridize to any species-specific probe tested, suggesting the presence of unrecognized Theileria variants or genotypes. Nine samples that gave Theileria spp. signal and two samples that gave T. equi specific signal were sent for sequence analysis and the A and D genotypes of T. equi were found. In addition, T. annulata, B. ovis, and B. canis species were detected in the samples and verified by sequence analysis in Turkey. More research is needed to understand the clinical impact of atypical piroplasm infections in equids. PMID- 30290889 TI - Immune response biomarkers in human and veterinary research. AB - Biomarkers are increasingly utilised in biological research and clinical practice for diagnosis of disease, monitoring of therapeutic prognosis, or as end points in clinical studies. Cytokines are small molecules that orchestrate immune responses and as such have great potential as biomarkers for both human and veterinary fields. Given the ease of sampling in the blood, and their high prevalence in clinical applications we will focus on protein detection as an area for biomarker discovery. This is facilitated by new technological developments such as digital ELISA that have led to significant increases in sensitivity. Two highly relevant examples include type I interferons, namely IFNalpha, that is now directly quantifiable by digital ELISA from biological samples. The application of this approach to the study of the unique bat interferon response may reveal novel findings with applications in both human and veterinary research. As a second example we will describe the use of CXCL10 as a disease biomarker in Tuberculosis, highlighting findings from human and mouse studies that should be considered in veterinary research. In summary, we describe how cytokines may be applied as novel biomarkers and illustrate two key examples where human and veterinary research may complement each other in line with the One Health objectives. PMID- 30290888 TI - Quantification of Toxoplasma gondii in the tissues of BALB/c mice after immunization with nanoliposomal excretory-secretory antigens using Real-Time PCR. AB - BACKGROUND: Toxoplasmosis is an infectious disease caused by the intracellular parasite Toxoplasma gondii. Although almost 1/3 of the world's population are seropositive, there is no effective vaccine against toxoplasmosis. Therefore, the development of an effective vaccine for control of toxoplasmosis is one of major concerns in parasitology. The aim of this study was to evaluate the efficacy of nano-liposomal excretory-secretory antigens (NLESA) in BALB/c mice. MATERIALS AND METHODS: Excretory-secretory antigens (ESA) was obtained from tachyzoites, encapsulated in the liposome and studied by scanning electron microscope. BALB/c mice were immunized with NLESA and ESA, sterile phosphate-buffered saline (PBS). Immunization was performed three times at 14-day intervals and challenged with 1 * 104 tachyzoites of T. gondii RH strain four weeks later. The parasite load of mice blood, brain and spleen tissues were determined using quantitative PCR targeted at the repeated element (RE) gene. RESULTS: The immunization with NLESA and ESA induced a significant increase of anti-Toxoplasma IgG antibody compared with PBS group (P < 0.05). After challenge with tachyzoites, qPCR analyses showed significant reduction of parasite load in NLESA and ESA immunized mice compared with control group (P < 0.05). Also, NLESAs were more effective than ESAs and showed significantly reduced parasite load in blood (P = 0.001) and brain tissue (P = 0.01). DISCUSSION: The vaccination with NLESA showed more promising results comparing to ESA. Further studies are recommended in order to achieve effectiveness of the vaccine against T. gondii.

PMID- 30290890 TI - Pentraxin 3 is up-regulated in epithelial mammary cells during Staphylococcus aureus intra-mammary infection in goat. AB - Pentraxin 3 is the prototypic long pentraxin and is produced by different cell populations (dendritic cells, monocytes/macrophages, endothelial cells, and fibroblasts) after pro-inflammatory stimulation. Different studies demonstrated the up-regulation of PTX3 during mastitis in ruminants, but its role is still unknown. We first investigated the conservation of PTX3 sequence among different species and its pattern of expression in a wide panel of organs from healthy goats. We studied the modulation of PTX3 during natural and experimental mammary infection, comparing its expression in blood, milk and mammary tissues from healthy and Staphylococcus aureus infected animals. We confirmed the high conservation of the molecule among different species. Goat PTX3 was expressed at high levels in bone marrow, mammary gland, aorta, rectum, pancreas, skin and lungs. PTX3 was up-regulated in epithelial mammary cells and in milk cells after S. aureus infection, suggesting that it represents a first line of defense in goat udder.

PMID- 30290902 TI - Brentuximab vedotin for paediatric relapsed or refractory Hodgkin's lymphoma and anaplastic large-cell lymphoma: a multicentre, open-label, phase 1/2 study. AB - BACKGROUND: Despite remarkable progress in the treatment of newly-diagnosed classical Hodgkin's lymphoma and systemic anaplastic large-cell lymphoma, treatment of relapsed or refractory disease remains challenging. The aims of this study were to assess the safety, tolerability, recommended phase 2 dose, and efficacy of brentuximab vedotin in paediatric patients with relapsed or refractory Hodgkin's lymphoma or systemic anaplastic large-cell lymphoma. METHODS: This open-label, dose-escalation phase 1/2 study was done at 12 centres across eight countries (France, Germany, Italy, Mexico, The Netherlands, Spain, UK, and USA). We recruited paediatric patients aged 7-18 years with relapsed or refractory classical Hodgkin's lymphoma or systemic anaplastic large-cell lymphoma, for whom standard treatment was unavailable or no longer effective. Participants were allocated to receive brentuximab vedotin at 1.4 mg/kg (phase 1) or 1.8 mg/kg (phases 1 and 2) via intravenous infusion once every 3 weeks for up to 16 cycles. Dose escalation was done via a 3+3 design. Key exclusion criteria were stem-cell transplantation less than 3 months before administration of the first dose of study drug, presence of cytomegalovirus infection after allogeneic stem-cell transplantation, previous treatment with an anti-CD30 antibody, and concurrent immunosuppressive or systemic therapy for chronic graft-versus-host disease. Primary outcomes were safety profile in the safety-evaluable population and maximum tolerated dose, recommended phase 2 dose, pharmacokinetics (phase 1), and proportion of patients who achieved best overall response (phase 2; evaluated by an independent review facility) in the response-evaluable population. This trial is registered with ClinicalTrials.gov, number NCT01492088. FINDINGS: Between April 16, 2012, and April 4, 2016, we screened 41 paediatric patients and enrolled 36 (aged 7-18 years), of whom 19 had relapsed or refractory classical Hodgkin's lymphoma and 17 had relapsed or refractory systemic anaplastic large cell lymphoma. At the data cutoff (Oct 12, 2016), all 36 patients had discontinued study drug treatment; the most common reason was progressive disease (15 patients). The maximum tolerated dose was not reached. The recommended phase 2 dose was 1.8 mg/kg. The proportion of patients who achieved overall response was 47% (95% CI 21-73) for classical Hodgkin's lymphoma and 53% (28-77) for systemic anaplastic large-cell lymphoma. All 36 patients had a treatment-emergent adverse event and 16 patients (44%) had at least one grade 3 or worse treatment emergent adverse event. The most common treatment-emergent adverse events were pyrexia (16 [44%] of 36) and nausea (13 [36%]). The most common grade 3 or worse treatment-emergent adverse events were neutropenia (four [11%]), increased gamma glutamyl transpeptidase (two [6%]), and pyrexia (two [6%]). 12 (33%) patients had transient, limited-severity peripheral neuropathy. Eight patients (22%) had a serious adverse event; three (8%) had a drug-related serious adverse event. One patient died of cardiac arrest (disease progression of a large huge mediastinal mass, unrelated to the study drug). Paediatric pharmacokinetic profiles were consistent with those from studies of adult patients. INTERPRETATION: Brentuximab vedotin has manageable toxicity and is associated with clinically meaningful responses in paediatric patients with relapsed or refractory Hodgkin's lymphoma or systemic anaplastic large-cell lymphoma, and could allow subsequent stem-cell transplantation in some patients who were initially ineligible for stem-cell transplantation. FUNDING: Millennium Pharmaceuticals Inc. PMID- 30290903 TI - Intensive treatment strategies in advanced-stage Hodgkin's lymphoma (HD9 and HD12): analysis of long-term survival in two randomised trials. AB - BACKGROUND: Although intensified chemotherapy regimens have improved tumour control and survival in advanced-stage Hodgkin's lymphoma, data on the long-term sequelae are scarce. We did preplanned follow-up analyses of the German Hodgkin Study Group (GHSG) trials HD9 and HD12 to assess whether the primary results of these trials-which had shown that intensive initial therapy in advanced-stage Hodgkin's lymphoma has a beneficial effect on treatment outcomes-would continue with longer follow-up. METHODS: In HD9 (Feb 1, 1993, to March 10, 1998), 1282 patients with newly diagnosed, histology-proven, advanced-stage Hodgkin's lymphoma received eight alternating cycles of COPP and ABVD (COPP/ABVD), eight cycles of bBEACOPP, or eight cycles of eBEACOPP. In HD12 (Jan 4, 1999, to Jan 13, 2003; registered with ClinicalTrials.gov [NCT00265031]), 1670 patients with newly diagnosed, histology-proven, advanced-stage Hodgkin's lymphoma received eight cycles of eBEACOPP or four cycles of eBEACOPP plus four cycles of bBEACOPP (4 + 4), plus consolidation radiotherapy to initial bulk and residual disease or no radiotherapy, to analyse two non-inferiority objectives. In both trials, randomisation was done centrally in the GHSG trial coordination centre using the minimisation method including a random component, stratified according to centre, age, stage, international prognostic score, the presence or absence of a large mediastinal mass, and bulky disease. Patients and investigators were not masked to treatment allocation. All analyses were done on the intention-to-treat principle. The primary endpoint of this follow-up analysis was progression-free survival (time from first diagnosis to progressive disease, relapse, or death from any cause or censoring at the date of last information on disease status). To assess whether long-term outcome might be impaired by long-term sequelae, we analysed overall survival and second primary malignant neoplasm incidence as key secondary endpoints. FINDINGS: Median observation time was 141 months (IQR 101 204) in HD9 and 97 months (69-143) in HD12. For HD9 trial patients, 15-year progression-free survival was 57.0% (95% CI 50.0-64.0) for COPP/ABVD, 66.8% (61.9 71.8) for bBEACOPP, and 74.0% (69.0-79.0) for eBEACOPP, 15-year overall survival was 72.3% (95% CI 66.5-78.1), 74.5% (70.1-78.9), and 80.9% (76.7-85.0), respectively. Progression-free survival and overall survival in the eBEACOPP group remained significantly better than in the COPP/ABVD group (hazard ratio [HR] 0.53, 95% CI 0.41-0.69, p<0.0001, and 0.68, 0.50-0.93, p=0.015, respectively). The 15-year cumulative incidence of second primary malignant neoplasms was 7.2% (95% CI 3.7-10.7) after COPP/ABVD, 13.0% (9.1-16.9) after bBEACOPP, and 11.4% (7.6-15.1) after eBEACOPP. For HD12 trial patients, non inferiority of 4 + 4 was shown, with 10-year progression-free survival of 82.6% (95% CI 79.6-85.6) for eBEACOPP and 80.6% (77.4-83.7) for 4 + 4 (HR 1.13 [0.89 1.43], within non-inferiority margin of 1.50), and 10-year overall survival of 87.3% (95% CI 84.7-89.9) and 86.8% (84.2-89.4), respectively (HR 1.02 [95% CI 0.77-1.36]). Among 555 (37%) patients with residual disease after chemotherapy, omission of radiotherapy was associated with significantly worse 10-year progression-free survival (89.7% [95% CI 85.8-93.6] radiotherapy vs 83.4% [78.2 88.5] for no radiotherapy; p=0.027) and 10-year overall survival (94.4% [91.4 97.3] vs 88.4% [83.8-93.0]; p=0.025). 10-year cumulative second primary malignant neoplasms incidence was 6.4% (95% CI 3.3-9.5) for 4 + 4 and 8.8% (5.2-12.4) for eBEACOPP. INTERPRETATION: Long-term follow-up of HD9 and HD12 shows an ongoing benefit of intensive first-line treatment and consolidation radiotherapy to residual disease in terms of progression-free survival and overall survival. Our results support the use of eBEACOPP in advanced-stage Hodgkin's lymphoma. However, because late toxicities such as second primary malignant neoplasms contribute to mortality, less toxic but equally effective treatments need to be developed to further improve overall survival. FUNDING: Deutsche Krebshilfe e.V. PMID- 30290904 TI - Passive transfer of anti-HBc after intravenous immunoglobulin administration in patients with cancer: a retrospective chart review. AB - BACKGROUND: Patients previously infected with hepatitis B virus (HBV; indicated by positivity for anti-HBc) can experience HBV reactivation during cancer chemotherapy. Intravenous immunoglobulin infusion, which is frequently used in supportive care, might facilitate passive transfer of anti-HBc. We aimed to estimate the probability of passive transfer of anti-HBc after intravenous immunoglobulin infusion in patients with cancer. METHODS: We reviewed institutional databases to identify adult patients who received outpatient chemotherapy between Jan 1, 2004, and Dec 31, 2011, at the University of Texas MD Anderson Cancer Center, Houston, TX, USA. Eligible patients had received intravenous immunoglobulin therapy, had tested negative for both anti-HBc and HBsAg before infusion, and had been tested for anti-HBc after infusion. The primary endpoint was the proportion of patients who became positive for anti-HBc after intravenous immunoglobulin infusion. FINDINGS: 950 of 18 874 patients who underwent chemotherapy within the study time frame received intravenous immunoglobulin, of whom 870 had been tested for anti-HBc before infusion. 199 patients who were negative for anti-HBc before receiving intravenous immunoglobulin were retested after infusion, of whom 29 (15% [95% CI 10-20]) became positive for anti-HBc. The probability of anti-HBc conversion at 1 week after intravenous immunoglobulin infusion was 34% (95% CI 22-48) and at 12 weeks was 4% (2-7). INTERPRETATION: Conversion of patients from anti-HBc negativity to anti-HBc positivity was common after intravenous immunoglobulin administration. However, the probability of a positive test decreased with time since infusion. Positive anti-HBc tests done shortly after intravenous immunoglobulin infusion should be interpreted with caution because they might indicate passive transfer instead of true infection. FUNDING: None. PMID- 30290905 TI - Thalidomide before and after autologous stem cell transplantation in recently diagnosed multiple myeloma (HOVON-50): long-term results from the phase 3, randomised controlled trial. AB - BACKGROUND: In patients with recently diagnosed multiple myeloma, the HOVON-50 phase 3 trial showed improved event-free survival for thalidomide-containing induction and maintenance regimens (in conjunction with high-dose melphalan and autologous stem cell transplantation [auto-SCT]) after a median of 52 months of follow-up, by comparison with regimens containing classical cytotoxic drugs. In this follow-up analysis, we aimed to determine the long-term effects of thalidomide in induction and maintenance therapy in multiple myeloma. METHODS: In this open-label, phase 3 randomised controlled trial, patients with recently diagnosed multiple myeloma were recruited from 44 Dutch and Belgian hospitals. Participants had been diagnosed with multiple myeloma of Durie-Salmon stage II or III and were aged 18-65 years. Patients were randomly assigned (1:1) either to receive three 28-day cycles of vincristine (0.4 mg, intravenous rapid infusion on days 1-4), doxorubicin (9 mg/m2, intravenous rapid infusion on days 1-4) and dexamethasone (40 mg, orally on days 1-4, 9-12, and 17-20; control group); or to receive the same regimen, but with thalidomide (200-400 mg, orally on days 1-28) instead of vincristine (thalidomide group). No masking after assignment to intervention was used. Patients were randomly assigned to groups, stratified by centre and treatment policy (one vs two courses of high-dose melphalan and auto SCT). After stem cell harvest, patients received one or two courses of 200 mg/m2 melphalan intravenously with auto-SCT. Patients with at least a partial response to high-dose melphalan and auto-SCT were eligible for maintenance therapy, starting 2-3 months after high-dose melphalan. Patients in the control group received maintenance therapy with interferon alfa (3 * 106 international units, subcutaneously, three times weekly). Patients in the thalidomide group received thalidomide as maintenance therapy (50 mg, orally, daily). Maintenance therapy was given until relapse, progression, or the occurrence of adverse events. The primary endpoint of the study was event-free survival (EFSc; censored at allogeneic stem cell transplantation), analysed by intention to treat. The study is closed for enrolment and this Article represents the final analysis. This trial was registered with the Netherlands Trial Register, number NTR238. FINDINGS: Between Nov 27, 2001 and May 31, 2005, 556 patients were enrolled in the study, of whom 536 (96%) were eligible for evaluation and were randomly allocated (268 [50%] to the control group and 268 [50%] to the thalidomide group). These 536 patients were assessed for the primary endpoint of EFSc. At an extended median follow-up of 129 months (IQR 123-136), EFSc was significantly longer in the thalidomide group compared with the control group (multivariate analysis hazard ratio [HR] 0.62, 95% CI 0.50-0.77; p<0.0001). Thalidomide maintenance was stopped because of toxicity in 65 (42%) of 155 patients in the thalidomide group (neuropathy in 49 [75%] patients, skin reactions in four [6%] patients, fatigue in two [3%] patients, and as other symptoms [such as abdominal pain, pancreatitis, and dyspnoea] in ten [15%] patients). 24 (27%) of 90 patients in the control group discontinued protocol treatment during maintenance therapy with interferon alfa because of toxicity (five [21%] patients with psychiatric side-effects, five [21%] patients with flu-like symptoms, four [17%] patients with haematological toxicity [thrombocytopenia and leucocytopenia], three [13%] patients with skin reactions, and seven [29%] patients with other symptoms [such as infections, cardiomyopathy, and headache]). The frequency of second primary malignancies was similar in both groups. There were 23 second primary malignancies in 17 patients in the control group and 29 second primary malignancies in 24 patients in the thalidomide group. There were 19 treatment related deaths in the control group, and 16 treatment-related deaths in the thalidomide group. INTERPRETATION: Our data indicate that thalidomide-based treatment could be a treatment option for patients with multiple myeloma who are eligible for auto-SCT who live in countries without access to proteasome inhibitors or lenalidomide. However, careful follow-up and timely dose adjustments are important to prevent the development of thalidomide-induced neurotoxicity. FUNDING: The Dutch Cancer Foundation. PMID- 30290906 TI - [Screening for familial hypercholesterolemia from low-density lipoprotein cholesterol levels at admission in the coronary care unit]. AB - BACKGROUND: Familial hypercholesterolemia (FH) is a frequent genetic disorder that leads to premature atherosclerosis and coronary artery disease. However, knowledge of FH by cardiologists is weak, and FH remains underdiagnosed in France. FH should be suspected when low-density lipoprotein cholesterol (LDLc) levels exceed 1.9g/L (4.9mmol/L) without lipid lowering therapy. PURPOSE: This multicenter retro- and prospective observational study aimed at estimating the prevalence of high LDLc levels in patients admitted in coronary care units, and the impact for the personal and familial follow-up for lipid status. METHODS: Retrospective analysis of all plasma lipid measurements performed at admission in coronary care unit of 4 hospitals in 2017. Retrospective analyses of demographic, clinical, and coronary data of consecutive patients with LDLc levels>=1.9g/L. Prospective 1 year follow-up focused on lipid levels, treatments, and personal and familial screening for FH. RESULTS: Lipid measurement has been performed in 2172 consecutive patients, and 108 (5%) had LDLc level>=1.9g/L (mean age 64+/-14 years, men 51%). The primary cause of the hospitalisation was acute coronary syndrome (78%), and 22% of patients were free off coronary artery disease. Lipid lowering therapy was present in 9% of patients at admission, and 84% at discharge, with high statins regimen. At 1-year follow-up, control of LDLc level was not performed in 20% of patients, and statin dose was decreased (36%) or withdrawn (7%) in 43%. Lipid measurement has been performed in at least one first degree relative in 37% of patients, and genetic exploration has been done for 3 patients. CONCLUSIONS: Screening of FH in CCU should be routinely performed using the Dutch Score when LDLc is above 1.9g/L. Individual and familial management of patients at high risk for FH screened in CCU should be optimized, both for diagnosis and therapeutic purposes.

PMID- 30290908 TI - [An unusual cause of hypertension]. AB - Secondary hypertension is relatively rare. Its etiologies are essentially renal or endocrine. The adrenocortical carcinoma, a rare malignant tumor, is one of the most exceptional causes of hypertension. We report the case of a young woman presenting with hypertension and ascites of great abundance. She had hypokalemia, hepatic cytolysis and cholestasis. Thoracic, abdominal and pelvic CT scans showed adrenal mass, liver and lung nodules, osteolytic lesions of the sacrum. The biopsy of liver nodules confirmed the diagnosis of a metastatic malignant adrenocortical carcinoma. The hormonal investigations revealed cortisol and testosterone hypersecretion. The evolution was quickly fatal, the patient passed out a few days after her hospitalization.

Its main feature is the existence of many deep heart-related ventricular trabeculations, generally located at the level of the apex of the left ventricle. Diagnosis is based on echocardiography and magnetic resonance imaging (MRI), and may be difficult in the atypical forms. The clinical presentation and the prognosis are very variable. Familial forms are not rare, ordering a family screening. PMID- 30290910 TI - Reduction of radiation exposure associated with renewal of the radiologic systems in coronary interventions. AB - PURPOSE: Interventional coronary procedures are an important source of radiation. This study sought to evaluate the effect of the renewal of the radiologic system on patient exposure during diagnostic coronary angiography (DCA) and percutaneous coronary interventions (PCIs). METHODS: DCA and PCIs were obtained from three centres, which renewed their radiologic systems during their participation in the multicentre prospective observational RAY'ACT-2 study. Data were analysed from the months before and after the radiologic system was changed. The primary outcomes were the dose reduction estimated by the kerma.area product (KAP in Gy.cm2) and the ratio of the KAP to fluoroscopy time (Gy.cm2.min-1). RESULTS: A total of 2148 patients underwent DCA (1575 before and 573 after the system change), and 1563 underwent PCI (1196 before and 367 after). A change in the radiologic system was associated with a KAP reduction of 43% for DCA (median [interquartile range]: 18.1Gy.cm2 [10.2-34.0] versus 31.5 [19.0-49.0], P<0.0001), and 38% for PCI (42.2Gy.cm2 [23.8-81.7] versus 70.1 [42.0-109.0], P<0.0001). Fluoroscopy time did not vary significantly, and the ratio KAP to fluoroscopy time significantly decreased by 54%. The dose reduction was homogeneous between the three centres and between different manufacturer's systems. CONCLUSIONS: In this multicentre study, the renewal of the radiologic system was associated with a highly significant 40%-50% reduction in radiation dose, irrespective of the manufacturer. A close interaction between manufacturers and operators is needed to optimise the use of new equipment and the effectiveness of radiation reduction tools and techniques.

The patient was followed for coronary artery disease. Low blood pressures were responsible for inferior acute myocardial infarction that revealed a sub occlusive stenosis of the right coronary artery. PMID- 30290913 TI - Speckle tracking echocardiography in systemic sclerosis: A useful method for detection of myocardial involvement. AB - BACKGROUND: Systemic sclerosis is a multisystem disorder characterized by tissue fibrosis and organ damage. Heart involvement is one of the main factors shortening survival, which may be underestimated by conventional echocardiography measurements. Two-dimensional speckle-tracking echocardiography is a powerful novel modality to assess subclinical myocardial dysfunction. AIM: The aim of this study is to investigate heart involvement in systemic sclerosis patients, and to determine the usefulness of ventricular longitudinal deformation using the Two dimensional speckle tracking technology for an early detection of ventricular dysfunction. PATIENTS AND METHODS: Between May 2016 and September 2016, 25 patients with systemic sclerosis and 25 healthy subjects underwent echocardiography to assess heart abnormalities and the strain of the two ventricles using two dimensions' speckle tracking echography. RESULTS: The two groups were comparable in age and gender. Despite comparable left ventricle systolic function (left ventricular ejection fraction patients 64.58+/-8.87 vs. in healthy 68.2+/-7.41, P=0.19), patients presented altered longitudinal peak systolic strain values (global longitudinal strain: patients -17.42+/-1.62 vs. healthy -19.24+/-8.85, P<0.0001). Despite comparable pulmonary artery systolic pressure, there was a significant alteration in right ventricular systolic and diastolic function assessed by standard measurement. Longitudinal peak systolic strain of the right ventricle was significantly lower in patients compared with controls (P<0.01). CONCLUSION: Ventricular deformation analysis by two dimensions' speckle tracking echocardiography appears to be a sensitive method to detect early ventricular impairment in patients with systemic sclerosis. PMID- 30290912 TI - [Echocardiographic profile of Congolese hypertensive patients]. AB - OBJECTIVES: To assess echocardiographic aspect of Congolese hypertensive patients, and to identify predictive factors of left ventricular hypertrophy (LVH). PATIENTS AND METHODS: A transversal study was lead in Brazzaville from January 2011 to December 2013 (36 months). In total, 1125 hypertensive patients under treatment underwent transthoracic echocardiography. The test was carried out either as part of an initial assessment of the hypertension disease or during the development of evocative symptom or complication. Patients' sociodemographic data and echocardiographic parameters were collected and analyzed. RESULTS: There were 621 males (55.2%) and 504 females (44.8%), mean age 54.7+/-12 years. The main indication of the test were the hypertension initial evaluation in 792 cases (70.4%), dyspnea in 122 cases (10.8%), investigation of ischemic stroke in 101 cases (9%), cardiac failure and chest pain in respectively 58 and 52 cases. 5.3+/ 4.7 years known duration of hypertension status was associated with overweight/obesity in 829 cases (73.7%), physical inactivity in 669 cases (59.5%), hypertension family history in 540 cases (48%), diabetes mellitus in 122 cases (10.8%), dyslipidemia in 82 cases (7.3%), smoking in 29 cases (2.6%). Echocardiographic test was abnormal in 590 cases (52.4%) and showed hypertrophic cardiomyopathy in 510 cases (45.2%), dilated and hypertrophic cardiomyopathy in 46 cases (4.1%), dilated cardiomyopathy with systolic dysfunction in 31 cases (2.8%), coronary artery disease in 4 cases (0.4%). LVH was concentric in 470 cases (84.6%), eccentric in 70 cases (12.6%), and in 16 cases (3%), it was a concentric left ventricular remodeling. The left ventricular's systolic ejection fraction average was 70.5+/-9.3%, relaxation disorders in 480 cases (42.6%). Age, male gender, income, known duration of hypertension and treatment were predictive factors of LVH. CONCLUSIONS: Echocardiographic profile of the Congolese hypertensive is quite various, left ventricular hypertrophy is the most predominant abnormality. Efficient management on the hypertension will lead to reduce its morbidity and mortality.

AB - INTRODUCTION: High-risk pulmonary embolism (PE) accounts for 5% of total acute PE and is a life-threatening emergency requiring immediate therapeutic management by fibrinolysis. The objective of this work is to describe the experience of thrombolysis in high-risk PE in a cardiology department in Togo. PATIENTS AND METHODS: This is an analytical and descriptive study carried out in the cardiology department of the Campus teaching hospital of Lome over a period of 5 years (August 2012 to July 2017) concerning patients hospitalized for high-risk mortality PE and having undergone streptokinase thrombolysis. RESULTS: Twenty eight of the 102 PE were at high risk of mortality (27.5%). They were 9 men and 19 women with an average age of 61.9+/-14.1 years. The mean systolic blood pressure was 65mmHg and 50% of the patients were placed on dobutamine. Thrombolysis was performed in 22 of the 28 patients (78.6%). Eighteen patients had a short protocol and 4 a long protocol. The mortality rate was 32.1% or 13.6% in the thrombolysis PE versus 100% in the non-thrombolysis PE (P=0.01). Causes of death in thrombolysis were persistent shock (2 cases) at the end of thrombolysis and sudden death occurred 1 month after hospitalization. The average hospital stay was 18.8 days. CONCLUSION: The high-risk PE remains today a pathology burdened with heavy mortality. Thrombolysis remains the first treatment to reduce this mortality. PMID- 30290915 TI - [Obesity, high blood pressure and physical activity levels in a black African population]. AB - PURPOSE OF THE STUDY: To determine the prevalence of general and abdominal obesity and to describe their association with high blood pressure and physical activity levels in a peri-urban population in West Africa. METHODS: A cross sectional study was conducted in Abidjan (Cote d'Ivoire) in the Anonkoi 3 district, from 24 April to 23 May 2014. Obesity, abdominal obesity and physical activity levels were assessed. Blood pressure was measured. The data were entered on the Epi data software (version 3.1) and analyzed with the R studio software version 1.1.447. The existence of associations was demonstrated by the Pearson Khi2 test at the 0.05 significance level. A multivariate analysis was performed. RESULTS: We recruited 486 adults 18 years of age and older, including 327 women and 159 men. The average age was 36.1 years with a standard deviation of 12.83 years. The prevalence of obesity was 14.8 %, that of abdominal obesity 50.8 % or more than half of the population. Females (P=0.000), ages 30 years and older (P=0.003), high blood pressure (P=0.000) and low activity (P=0.033) were significantly associated with obesity and abdominal obesity. Multivariate analysis showed that the relationship between female gender and abdominal obesity was very significant (OR=48.52; 95 % CI). CONCLUSION: This village located in a municipality of Abidjan has a heterogeneous population. This one adopts the sedentary habits of the city. PMID- 30290916 TI - [Analysis of cardiovascular complications occurring during inter-hospital transfers of patients with non-ST elevation myocardial infarction]. AB - AIM OF THE STUDY: Patients with non ST-segment elevated acute coronary syndrome justify specific management in a hospital with an Intensive Cardiac Care Unit. In our area, these transfers are often provided by the Emergency Medical Service. Nevertheless we wonder whether a quasi-systematic medicalization of these patients is rational. PATIENTS AND METHOD: We tried to authenticate the need for medicalization of these patients through a prospective study including any patient with acute non-ST elevation Coronary Syndrome managed in one of the peripheral hospitals of the area and transferred to the major hospital center in La Roche-sur-Yon. We noted all the complications that occurred during the transfer and, if need be, when these complications required medical intervention. RESULTS: Out of 226 patients included, 19 had a complicated form of acute non-ST elevation Coronary Syndrome. Out of the remaining 207 patients, 16 (7.7 %) showed a complication during their transfer, 5 of which underwent a medical intervention, none of which was immediately vital. Nevertheless, the statistical analysis did not highlight any significant worsening factors. CONCLUSION: The low rate of complications occurring during the transfer of initially stable patients encourages us to limit our indications of medicalization in favour of only the unstable patients or having a complication of their non-ST elevation acute coronary syndrome. PMID- 30290917 TI - [Prevalence and determinants of the increased carotid intima-media thickness in a population of 1203 black African hypertensive]. AB - OBJECTIVES: To evaluate the prevalence and determinants of increased carotid intima-media thickness (IMT) in a population of black hypertensive patients and it influence of on the assessment of their overall cardiovascular risk. PATIENTS AND METHODS: This was a 16-month, cross-sectional study conducted in the outpatient unit of the cardiology department of the Campus teaching hospital of Lome, and included 1203 hypertensive patients, both sexes, aged 35 years and more. Each patient benefited from a carotid IMT measure. Carotid IMT was increased if it was>0.9mm and the plaque was defined as a carotid IMT>1.2mm. RESULTS: The mean age of our patients was 53.3+/-10.4 years with a sex ratio of 1.6 in favor of women. The duration of hypertension was less than 5 years in 56.7% and hypertension was grade 1 in 47.7% of cases. The mean carotid IMT was 0.89mm+/-0.20. The prevalence of the increased carotid IMT was 45.8% and that of an atheroma plaque was 15.8%. Carotid IMT was correlated with age (P?0.0001), duration of arterial hypertension (P=0.01), history of stroke (P?0.0001), and presence of left ventricular hypertrophy to cardiac ultrasound (P=0.01). The overall cardiovascular risk was modified after taking into account the carotid IMT. An increase in cardiovascular risk was observed in 30.5% of hypertensive patients. CONCLUSION: Increased carotid intima-media thickness is frequent in Togolese hypertension. The determining factors are age, duration of arterial hypertension, left ventricular hypertrophy and stroke. The systematic measurement of the carotid intima-media thickness would better evaluate the overall cardiovascular risk for our patients. PMID- 30290918 TI - [Effect of frontal electrodes location on the electrocardiogram quality of obese subjects: Roots versus limb of extremities]. AB - INTRODUCTION: In obese patients, standard recording of electrocardiogram seems to have specific electrical modifications related to obesity. These modifications could be minimized by the use of alternative recording techniques. The aim of this study is to evaluate the effect of the recording technique (standard versus Lund) on the electrocardiogram quality in healthy obese patients. METHOD: This is an observational and descriptive study carried out in emergency medical services during a two years period. Healthy subjects with an age over 18 years and a body mass index (BMI)>=30kg/m2 were included. Each participant had an electrocardiogram according to Lund's technique immediately followed by a standard recording. Deflections amplitude and their respective axes were compared between the two techniques. The primary endpoint was the frequency of microvoltage. The secondary endpoints were the flat T wave at the inferior and the left axial deviations. RESULTS: Fifty obese patients were included. The average BMI was 36.8+/-6.6kg/m2. The average age was 45+/-13 years with a sex ratio of 0.52. The standard technique was associated with a higher incidence of microvoltage (40% versus 20%, P=0.029) and flattening of the T wave (40% versus 18%, P=0.015). Analysis of the variance of the P, QRS and T wave axes did not find any difference between the two techniques. CONCLUSION: The Lund technique reduces the incidence of electrical abnormalities in the electrocardiogram of healthy obese patients.

PMID- 30290930 TI - Focus on Idiopathic Pulmonary Fibrosis: Advancing Approaches to Diagnosis, Prognosis, and Treatment. AB - As seen in this CME online activity (available at http://courses.elseviercme.com/694), idiopathic pulmonary fibrosis (IPF) is a specific form of chronic, progressive, fibrotic lung disease of unknown cause that is associated with substantial health-care utilization and high rates of mortality. The clinical symptoms of IPF are nonspecific and overlap with many pulmonary and cardiac diseases making differential diagnosis challenging. The American Thoracic Society/European Respiratory Society/Japanese Respiratory Society/Latin American Thoracic Association (ATS/ERS/JRS/ALAT) guidelines strongly recommend a multidisciplinary approach to the diagnosis of interstitial lung diseases; however, there are several limitations to the feasibility of this approach in clinical practice. Although early diagnosis is relevant to any chronic, progressive, and irreversible disorder, it is crucially important that effective treatments for IPF are prescribed without delay. A window of opportunity may exist during which time treatment can have optimal outcomes. Evidence on the clinical management of IPF is rapidly evolving, and key updates were made to the most recent ATS/ERS/JRS/ALAT guidelines. The widely used combination of prednisone, azathioprine, and N-acetylcysteine has now been associated with increased risk of hospitalization and death compared with placebo in patients with IPF. These treatments and others for IPF have been mostly supportive, but recently pirfenidone and nintedanib have demonstrated efficacy in reducing functional decline and disease progression in IPF. A pooled analysis of three phase 3 studies of pirfenidone found a significant 48% reduction in all cause mortality, and a pooled analysis of a phase 2 and two phase 3 studies of nintedanib found a significant 43% reduction in on-treatment mortality. As patient exposure to these two new drugs increases, data continue to emerge on how and when to use these medications and on how to manage their side effects. Finally, several medications targeting the fibrotic pathobiology of IPF are currently in development. Given the limited treatment options for IPF, enrollment in a clinical trial may be the best chance to delay or prevent progression of IPF. This CME-certified expert video roundtable from CHEST reviews the ATS/ERS/JRS/ALAT guidelines with a specific focus on accurate and timely diagnosis of IPF and the latest data on the treatment of IPF. PMID- 30290931 TI - Breathing Life Into COPD Management: Ongoing Monitoring, Pulmonary Rehabilitation, and Individualized Care. AB - As seen in this CME online activity (available at http://copdcme.elsevierresource.com/, COPD is characterized by pulmonary airflow obstruction that is not completely reversible. COPD presents clinically with diverse phenotypes ranging from relatively asymptomatic people to patients with severe chronic cough, abnormal sputum production, and dyspnea with exertion. Exacerbations accelerate the downward cycle of breathing difficulties, activity avoidance, and physical decline that characterizes progressive COPD. Consequently, patients with COPD should be repeatedly assessed for symptom severity and duration, previous exacerbations, the degree of airflow limitation, and confounding comorbidities. Spirometry should be used to clarify COPD prognoses and longitudinally classify the disease from mild to very severe. Conversely, spirometry does not always capture the wide-ranging effects of COPD on patient function and quality of life, and other clinical assessment tools and evaluation strategies should be used to longitudinally monitor patients. Although COPD cannot currently be cured, all disease stages can be treated to slow progression, minimize symptoms, prevent exacerbations, and maximize function and quality of life. Importantly, all patients should participate in comprehensive pulmonary rehabilitation regardless of disease stage. Patients and providers, however, can be unaware of potential benefits or reluctant to initiate this modality. In many practice settings, finding a pulmonary rehabilitation program to accept the patient can be difficult, highlighting the need for well-defined referral pathways. Almost all patients with COPD also require pharmacotherapy to control symptoms, reduce complications, and maximize lung function. Evidence based education that addresses individualized maintenance regimens are needed to improve long-term outcomes in COPD. Within this CME/CE Snapshot educational series, an expert pulmonologist and a primary care educator discuss how to best longitudinally evaluate patients with COPD and incorporate the principles of pulmonary rehabilitation to maximize patient function and quality of life. They explain therapeutic tailoring over the course of disease and describe the importance of engaging patients in shared decision-making to promote acceptance of the diagnosis, appropriate physical activity, and treatment adherence. PMID- 30290932 TI - Clinical Issues in Severe Asthma: Consensus and Controversies on the Road to Precision Medicine. AB - As seen in this CME online activity (available at http://courses.elseviercme.com/708e), the various forms of asthma affect > 300 million people globally and > 25 million people in the United States. Asthma related symptoms and exacerbations result in nearly 2 million ED visits annually, and many of these visits lead to inpatient hospital stays. There is an urgent need to improve the care of the estimated 5% to 15% of patients who have severe asthma. Importantly, studies have shown that severe asthma accounts for an outsized proportion of the disease-related morbidity, mortality, and health-care costs. Examining cohorts from several large patient networks that were created to better understand clinical presentations, biopsychosocial consequences, and long term outcomes of severe asthma revealed substantial disease burden, significant gaps in longitudinal care, and a clear need for additional treatment options. This CME-accredited Clinical Issues program is intended for allergists/clinical immunologists, pulmonologists, and other health-care providers involved in the management of patients with severe asthma. During the activity, a panel of expert faculty will discuss and debate a series of topics related to the evaluation and long-term treatment of various severe asthma phenotypes. Activity topics include education regarding (1) The classification of severe asthma to differentially diagnose patients with disease that is uncontrolled despite relatively intensive therapy; (2) potential phenotypes and available biomarkers, including strengths, limitations, and how to translate results into the selection of therapies; and (3) the different mechanisms of action, efficacy, and safety of biologic therapies that target the pathophysiology of severe asthma. The goal is to provide clinician learners with the latest evidence and a fresh perspective on evolving management paradigms for severe asthma. PMID- 30290933 TI - Confronting the Challenge of COPD: What Is New in the Approaches to Diagnosis, Treatment, and Patient Outcomes. AB - As seen in this CME online activity (available at http://courses.elseviercme.com/730), COPD is the third leading cause of death in the United States among people 65 years of age and older and the fourth leading cause of death among people 45 to 65 years of age. A recent survey reported that about 12 to 15 million people in the United States have physician-diagnosed COPD. However, COPD is significantly underdiagnosed, and data suggest as many as 12 million people in the United States have undiagnosed COPD. In addition to being underdiagnosed, COPD is significantly undertreated, with numerous literature sources indicating that patients with COPD are not receiving guideline concordant pharmacotherapy. Consistent with these sources, an analysis of claims data for > 50,000 patients with COPD indicated a high degree of undertreatment in these patients. For patients using an inhaler, adherence to inhaler medications and correct inhaler device technique are crucial to successful COPD management. However, the literature indicates > 50% of patients with COPD demonstrate poor medication adherence and rates of incorrect inhalation technique range from 35% to 85%. Studies have shown that regular training by a physician improved inhaler techniques among patients with COPD. Further, studies have shown that repeated instruction on inhalation techniques improved both adherence and quality of life outcomes. This CME-certified webcast provides insights into new approaches to identifying patients with undiagnosed COPD, the importance of early initiation of pharmacologic treatment in a guideline-congruent manner, and the importance of repeated patient training in correct inhaler techniques to improve adherence and patient outcomes. Additionally, the online program is part of a larger learning platform (available at https://copd.elsevierresource.com/) that provides free access to the latest clinical information related to the diagnosis and management of COPD. The COPD Learning Center is a freely accessible platform that aims to increase clinical knowledge by providing CME activities, research articles, and resources for health-care providers who treat patients with COPD.

He also experienced continuous palpitations, which were regular, not associated with chest pain or dizziness, and aggravated on exertion. He had not taken any medication for his condition, except for antipyretic agents, nor had he sought medical advice. He was a nonsmoker, had a history of past alcohol dependence, and had been hospitalized twice for acute pancreatitis due to hypertriglyceridemia. He had also been diagnosed with diabetes mellitus, presumably poorly controlled because he mentioned not taking any medication or having regular follow-up.

Three months prior to presentation, she had spent 45 days travelling through India and Thailand. She presented with no signs of traveler's disease such as fever or diarrhea during that trip. Two weeks following her return to France, the patient presented with an episode of bronchitis and received 5 days of treatment with cefixime (a third-generation cephalosporin). Despite this antibiotic treatment, her symptoms worsened and she developed, over the following 3 weeks, general weakness and arthralgia/myalgia. Due to the severity of hypoxemia, the patient was immediately transferred to the ICU. PMID- 30290952 TI - A 26-Year-Old Man With a Pleural Effusion and Headache. AB - CASE PRESENTATION: A 26-year-old man presented to the ED with dizziness and gait imbalance. He noted dizziness for 3 months, but symptoms progressed more rapidly over the last 3 weeks when he began experiencing nausea, vomiting, and "wobbly legs." These symptoms would worsen with physical exertion, especially when lifting heavy objects. On review of systems, he also reported subjective fevers and chills. He had no appreciable dyspnea, cough, chest pain, or increased sputum production. The patient recalled a history of "brain surgery" approximately 4 years prior to his presentation, but no further details could be provided at the time.

AB - CASE PRESENTATION: A 67-year-old man with a history of atrial fibrillation (AF) presented to his physician with symptoms of episodic, nighttime palpitations and excessive daytime sleepiness. Four years prior he underwent radiofrequency ablation after a confirmed diagnosis of AF with subsequent resolution of his palpitations. His palpitations returned approximately 1 year following the ablation. These events would occur only at night and awake him from sleep. Holter monitoring showed baseline sinus rhythm with multiple episodes of AF with rates of 75 to 169 beats/min. These events were all nocturnal and correlated with the symptom diary; episodes ranged from 45 min to 2 h. An echocardiogram showed normal left ventricular size and ejection fraction with a mildly enlarged right atrium (4.38 cm) and no evidence of pulmonary hypertension. PMID- 30290956 TI - Genomic Differences Between "Primary" and "Secondary" Muscle-invasive Bladder Cancer as a Basis for Disparate Outcomes to Cisplatin-based Neoadjuvant Chemotherapy. AB - BACKGROUND: Cisplatin-based neoadjuvant chemotherapy (NAC) followed by radical cystectomy (RC) is the standard of care for patients with muscle-invasive bladder cancer (MIBC). It is unknown whether this treatment strategy is appropriate for patients who progress to MIBC after treatment for prior noninvasive disease (secondary MIBC). OBJECTIVE: To determine whether clinical and genomic differences exist between primary and secondary MIBC treated with NAC and RC. DESIGN, SETTING, AND PARTICIPANTS: Clinicopathologic outcomes were compared between 245 patients with clinical T2-4aN0M0-stage primary MIBC and 43 with secondary MIBC treated with NAC and RC at Memorial Sloan Kettering Cancer Center (MSKCC) from 2001 to 2015. Genomic differences were assessed in a retrospective cohort of 385 prechemotherapy specimens sequenced by whole-exome or targeted exon capture by the Cancer Genome Atlas or at MSKCC. Findings were confirmed in an independent validation cohort of 94 MIBC patients undergoing prospective targeted exon sequencing at MSKCC. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Pathologic response rates, recurrence-free survival (RFS), bladder cancer specific survival (CSS), and overall survival (OS) were measured. Differences in somatic genomic alteration rates were compared using Fisher's exact test and the Benjamini-Hochberg false discovery rate method. RESULTS AND LIMITATIONS: Patients with secondary MIBC had lower pathologic response rates following NAC than those with primary MIBC (univariable: 26% vs 45%, multivariable: odds ratio=0.4 [95% confidence interval=0.18-0.84] p=0.02) and significantly worse RFS, CSS, and OS. Patients with secondary MIBC treated with NAC had worse CSS compared with cystectomy alone (p=0.002). In a separate genomic analysis, we detected significantly more likely deleterious somatic ERCC2 missense mutations in primary MIBC tumors in both the discovery (10.9% [36/330] vs 1.8% [1/55], p=0.04) and the validation (15.7% [12/70] vs 0% [0/24], p=0.03) cohort. CONCLUSIONS: Patients with secondary MIBC treated with NAC had worse clinical outcomes than similarly treated patients with primary MIBC. ERCC2 mutations predicted to result in increased cisplatin sensitivity were enriched in primary versus secondary MIBC. Prospective validation is still needed, but given the lack of clinical benefit with cisplatin-based NAC in patients with secondary MIBC, upfront RC or enrollment in clinical trials should be considered. PATIENT SUMMARY: A retrospective cohort study of patients with "primary" and "secondary" muscle invasive bladder cancer (MIBC) treated with chemotherapy before surgical removal of the bladder identified lower response rates and shorter survival in patients with secondary MIBC. Tumor genetic sequencing of separate discovery and validation cohorts revealed that chemotherapy-sensitizing DNA damage repair gene mutations occur predominantly in primary MIBC tumors and may underlie the greater sensitivity of primary MIBC to chemotherapy. Prospective validation is still needed, but patients with secondary MIBC may derive greater benefit from upfront surgery or enrollment in clinical trials rather than from standard chemotherapy.

AB - This work aims to demonstrate the ability to evaluate bulk thermal aging of aeronautical composite materials using Lamb waves. These composite materials are bi-dimensional woven composite structures with polymers matrix. More than 20 different thermal aging profiles are obtained by modulating the temperature and curing duration. The impact on material properties is evaluated using normalized destructive characterization and x-ray computed tomography. Lamb waves are generated and detected using a single 3 MHz phased array transducer in contact with the composite structure. In that way, a spatio-temporal image of elastic wave propagation in the composite material is obtained. The dispersion curves are calculated by using a bi-dimensional discrete Fourier transform or singular value decomposition to project the experimental data into the wavenumber-frequency domain. Both methods allow for accurate estimation of the Lamb wave dispersion curves. Thermal aging is then evaluated by comparing experimental data with a set of dispersion curves that correspond to different controlled thermal aging profiles. Our promising results open the door toward quantitative evaluation of composite material thermal aging on the runway.

PMID- 30290960 TI - Fetal environment and fetal intestine are sterile during the third trimester of pregnancy. AB - Recent next generation sequencing studies on host-associated microbiomes generated debatable conclusions regarding the central dogma of fetal gut sterility. These observations challenge the concepts that microbial colonization of the gut begins during and after birth as well as the concept of antigen independent prenatal maturation of mucosal-associated lymphoid tissue in ruminants and humans. The placental barrier varies markedly among mammalian species with mice and humans having haemochorial placentas (fetal tissue in direct contact with maternal blood) versus epitheliochorial placentation (maternal and fetal blood separated by six tissue layers) in ruminants. Therefore, this study re-examined the question of fetal gut sterility using the fetal lamb as a model ruminant species with the most complete placental barrier. Use of PCR and quantitative real-time PCR with three different pairs of universal bacterial primers (27 F and 1492R, HDA1 and HDA2, U2F and U2R) to amplify 16S rRNA gene did not generate detectable PCR products from samples collected from the fetal environment (placenta, amniotic fluid) and fetal intestine during the third trimester of pregnancy. Procedures to further enrich microbial DNA from total extracted DNA also resulted in no detectable genomic DNA. Moreover, use of 16S amplicon sequencing confirmed the absence of bacteria in the fetal environment during the third trimester of pregnancy. A 'No Template' control containing only PCR reagents generated sequences that could be clustered into OTUs at 97% similarity and assigned to bacterial genera, including Staphylococcus, Lactobacillus and Escherichia-Shigella. Use of multiple molecular based approaches to profile fetal environment-associated microbiota supports the conclusion that the fetal environment and fetal intestine remain sterile during the third trimester of pregnancy. The use of appropriate controls, both positive and no template, revealed inherent contamination in reagents and that variations in the data analysis pipeline can produce artificial microbial profiles from host tissues containing low microbial biomass. Finally, these findings confirm that extensive development of gut-associated lymphoid tissue in the ruminant fetal intestine, characterized by active B cell proliferation and immunoglobulin V gene somatic mutation, is not associated with exposure to bacterial DNA and antigens.

PMID- 30290962 TI - Chronic kidney disease measures and the risk of abdominal aortic aneurysm. AB - BACKGROUND AND AIMS: Despite its strong link to cardiovascular outcomes, the association of chronic kidney disease (CKD) with abdominal aortic aneurysm (AAA) has not been explicitly and comprehensively investigated. METHODS: In 10,724 participants in the Atherosclerosis Risk in Communities Study (aged 53-75 years during 1996-1998), we evaluated the associations of two key CKD measures - estimated glomerular filtration rate (eGFR) and urine albumin-to-creatinine ratio (ACR) - with incident AAA (AAA diagnosis in outpatient, hospitalization discharge, or death records). Additionally, we performed a cross-sectional analysis for the CKD measures and ultrasound-based abdominal aortic diameter in 4258 participants during 2011-2013. RESULTS: During a median follow-up of 13.9 years, 347 participants developed AAA. The demographically-adjusted hazard ratio (HR) was 4.44 (95% CI 1.58-12.49) for eGFR <30, 3.29 (1.89-5.72) for 30-44, 2.03 (1.29-3.19) for 45-59, and 1.62 (1.11-2.35) for 60-74 compared to eGFR >=90 mL/min/1.73 m2 and was 2.49 (1.28-4.87) for ACR >=300, 1.99 (1.40-2.83) for 30 299, and 1.46 (1.08-1.97) for 10-29 compared to ACR <10 mg/g. The associations were generally similar after accounting for additional confounders, such as smoking (although attenuated), or after stratifying by subgroups, including diabetes. The cross-sectional analysis also showed continuous positive associations of these CKD measures with aortic diameter, particularly at the distal aortic segment assessed. CONCLUSIONS: Reduced eGFR and elevated albuminuria were independently associated with greater incidence of AAA and greater abdominal aortic diameter. Our results suggest the potential usefulness of CKD measures to identify persons at high risk of AAA and the need to investigate pathophysiological pathways linking CKD to AAA. PMID- 30290963 TI - Epigenetic processing in cardiometabolic disease. AB - Albeit a consistent body of evidence supports the notion that genes influence cardiometabolic features and outcomes, the "non-genetic regulation" of this process is gaining increasing attention. Plastic chemical changes of DNA/histone complexes - known as epigenetic changes - critically determine gene activity by rapidly modifying chromatin accessibility to transcription factors. In this review, we describe the emerging role of chromatin modifications as fine tuners of gene transcription in adipogenesis, insulin resistance, macrophage polarization, immuno-metabolism, endothelial dysfunction and metabolic cardiomyopathy. Epigenetic processing participates in the dynamic interplay among different organs in the cardiometabolic patient. DNA methylation and post translational histone modifications in both visceral and subcutaneous adipose tissue enable the transcription of genes implicated in lipo- and adipogenesis, inflammation and insulin resistance. Along the same line, complex networks of chromatin modifying enzymes are responsible for impaired nitric oxide bioavailability and defective insulin signalling in the vasculature, thus leading to reduced capillary recruitment and insulin delivery in the liver, skeletal muscle and adipose tissue. Furthermore, changes in methylation status of IL-4, IFNgamma and Forkhead box P3 (Foxp3) gene loci are crucial for the polarization of immune cells, thus leading to adipose tissue inflammation and atherosclerosis. Cell-specific epigenetic information could advance our understanding of cardiometabolic processes, thus leading to individualized risk assessment and personalized therapeutic approaches in patients with cardiometabolic disturbances. The development of new chromatin modifying drugs indicates that targeting epigenetic changes is a promising approach to reduce the burden of cardiovascular disease in this setting. PMID- 30290964 TI - [Acquisition of clinical observation skills by medical students improves with discipline-based teaching. The example of neurological examination]. AB - INTRODUCTION: Since 2014-2015, practical teaching of clinical observation skills for 2nd year medical students at our faculty has been discipline-based; previously, each clinical lecturer had to cover all medical fields. We assessed the impact of this teaching reform on the neurological examination skills of medical students in a before-and-after study. METHODS: Pre-reform 3rd and post reform 2nd and 3rd year medical students (n=62, n=71 and 52, respectively) had to perform 7 neurological examination items, for which performance criteria had been pre-defined. Subsequently, we assessed whether the mean grade in neurological examination skills during the test at the end of the 2nd year was different between students who had received neurological teaching from a neurologist (n=29) or another specialist (n=102). RESULTS: The median [interquartile range] number of items acquired by post-reform 3rd year students (4 [2-5]) was higher than that of pre-reform 3rd year students (2 [1-3]; P<0.001), but lower than that of post reform 2nd year students (5 [4-6]; P=0.01). The mean grade obtained during the practical test was not different in students trained by a neurologist or another specialist. CONCLUSION: Acquisition of neurological examination skills improved after the teaching reform which consisted of: (1) a discipline-based practical teaching of clinical observation skills; (2) a training of clinical lecturers to teach a limited list of educational objectives; and (3) the introduction of a practical test at the end of the 2nd year of medical studies. However, there was a decline in clinical observation skills between 2nd and 3rd year medical students. PMID- 30290965 TI - Reconstruction of anthropogenic 129I temporal variation in the Japan Sea using a coral core sample. AB - The anthropogenic long-lived radionuclide 129I is receiving increased attraction as a new oceanic tracer in addition to usage as a fingerprint of radionuclide contamination of the marine environment. To demonstrate the robustness of 129I as an oceanic tracer in the Northwest Pacific area, specifically in the Japan Sea, the input history of 129I to surface seawater was reconstructed using a hermatypic coral core sample from Iki Island in the Tsushima strait. Iodine isotopes in each annual band were measured using AMS and ICP-MS after appropriate pre-treatments of small amounts of coral powder. The 129I/127I ratios in the 1940s were almost at background levels (<1 * 10-11) and increased abruptly in the early 1950s. Thereafter, the ratios continuously increased with some fluctuations; the maximum ratio, 7.13 +/- 0.72 * 10-11, being found in the late 1990s. After that period, the ratios remained nearly constant until the present time (2011). The 129I originated mainly from the nuclear weapons testings of the 1950s and the early 1960s, and from airborne releasing by nuclear reprocessing facilities. The dataset obtained here was used to construct a simple model to estimate the diffusion coefficient of 129I in the Japan Sea. The 129I/236U ratios over the observation period were also reconstructed to help constraining sources of 129I to the marine environment. Based on the results, the 129I/236U ratio obtained here could be an endmember of the water mass in the Kuroshio Current area of the Northwest Pacific Ocean.

AB - This meta-analysis aimed to systematically review current literature measuring the thickness of retinal nerve fiber layer (RNFL) in patients with myelin oligodendrocyte glycoprotein antibodies (MOG-ab) associated optic neuritis. Ten studies were enrolled and the results showed that the degree of RNFL loss in MOG ab-positive optic neuritis patients may not differ from that of AQP4-ab patients. However, patients who were positive for MOG-ab showed more severe RNFL loss than those who were seronegative.

AB - Using vehicles with engaged automated driving systems (ADS) ('highly automated driving', HAD) will substantially impact on future society's mobility, yet the current understanding of human psychobiology related to HAD is still limited. Hence, we synthesized evidence on the psychobiology of subjects using HAD, informing an integrative model of the psychobiology of HAD, and providing guidance for reporting future research on this topic. We included (non )randomized studies assessing human peripheral biology markers of in-vehicle users in real or simulated driving environments, using vehicles with vs. without engaged ADS, published in English until April 2018. We systematically searched Web of Science, SCOPUS, and PubMed. The search consisted of a combination of terms describing HAD and psychobiological parameters. Risk of bias was assessed regarding randomization, blinding, incomplete outcome data, selective outcome reporting, and other potential causes. We extracted data using predefined data fields. Four out of five studies included in this review (N = 194 subjects) reported associations of use of vehicles with vs. without engaged ADS with various psychobiological parameters, including heart rate, respiratory sinus arrhythmia (RSA), indicators of electrodermal activity (EDA), and masseter electromyography (EMG). Heart rate tended to be reduced during HAD along with increased EDA and EMG, with no clear indication for changes in RSA. We cannot exclude substantial risk of bias, among others because the status of engagement of ADS was mostly non-randomized. Yet, findings suggest that HAD goes along with tractable changes in peripheral biology. Informed by the conceptual endophenotype approach (Hellhammer et al., 2018, Psychoneuroendocrinology), we propose the Embodied Driving (EMBODD) model that describes how HAD reshapes vehicle use experience, and highlight how to make future ADS equipped vehicles successful regarding user's health. Based on the review, we suggest reporting guidelines for future research on the psychobiology of HAD. PMID- 30290969 TI - Suspicion of acute appendicitis in adults. The value of ultrasound in our hospital. AB - OBJECTIVE: To evaluate the accuracy of ultrasonography for the diagnosis of acute appendicitis in adults, to calculate the negative appendicectomy rate in operated patients and the accuracy of pre-defined diagnostic categories and to identify statistically significant signs and symptoms of acute appendicitis in ultrasonography. MATERIAL AND METHODS: Descriptive prospective study in which we collected the findings of the urgent ultrasonographies ordered in a one-year period for adult patients with pain in the right iliac fossa (RIF), along with their symptoms. We classified them in 5 different diagnostic categories presented in the radiological report: normal appendix, non-visible appendix and no secondary signs, non-conclusive, probable appendicitis, certain appendicitis. By mean of the Stata14 software descriptive analysis, T-test and Chi-square were performed and the data were compared with the final pathological report. RESULTS: Population: 139 patients (45% men, 55% women), mean age: 32,68 (15-84). Prevalence of acute appendicitis: 50,35% (70/139). Negative appendicectomy rate: 0%. Negative predictive value for the categories 1,2 and 3 taken together: 90,78%. Positive predictive value for the categories 4 and 5 taken together: 100%. Ultrasound sensibility and specificity 90% and 100%, respectively. Statistically significant signs and symptoms (p<0.05): RIF pain, fever, leukocytosis, left shift, visible appendix, non-compressibility, hyperechogenic fat, appendicolith and free fluid. CONCLUSION: Ultrasound is very accurate for the diagnosis of acute appendicitis in adults. PMID- 30290970 TI - Metastatic melanoma-asociated poliosis.

PMID- 30290972 TI - The chronic intestinal pseudo-obstruction subtype has prognostic significance in patients with severe gastrointestinal dysmotility related intestinal failure. AB - BACKGROUND & AIMS: Severe gastrointestinal dysmotility (GID) is a significant cause of chronic intestinal failure (CIF) with unclear benefits of sub classifying into Chronic Intestinal Pseudo-obstruction (CIPO) and non-CIPO sub types. We compared outcomes between CIPO and non-CIPO sub-types in a tertiary cohort of patients with CIF resulting from severe GID. METHODS: Adults with primary GID, commenced on home parenteral nutrition (HPN) over a 16-year period at a national referral centre, were included. All patients satisfied GID clinical criteria which mandated evidence of small bowel involvement either objectively (abnormal antroduodenal manometry) or pragmatically (failure to progress on small bowel feeding). Clinical outcomes including HPN dependency and survival were compared between CIPO and non-CIPO sub-types. RESULTS: Patients with primary GID requiring HPN (n = 45, age 38 +/- 2, 33 females, 23/45 (51%) CIPO, 22/45 (49%) non-CIPO) were included. Patients with CIPO had more surgical interventions (P = 0.03), higher incidence of bacterial overgrowth (P = 0.006), greater parenteral energy (P = 0.02) and volume requirements (P = 0.05). Overall, during a mean 6 years' follow-up, 36/45 (80%) patients remained HPN dependent. Multivariate analyses confirmed that the non-CIPO sub-type (P = 0.04) and catheter related blood stream infections/1000 days (P = 0.01) were predictive factors for time to discontinuing HPN. Overall 5-year survival on HPN was 85%, with no difference between sub-types (P = 0.83). CONCLUSIONS: The CIPO sub-type is associated with higher HPN dependency and should be recognized as a separate entity in severe GID. In multidisciplinary settings with continuous close monitoring of risks and benefits, our data confirm HPN is a safe, life-preserving therapy in severe GID related CIF. PMID- 30290973 TI - An internet-based approach for lifestyle changes in patients with NAFLD: Two-year effects on weight loss and surrogate markers. AB - BACKGROUND & AIMS: Interventions aimed at lifestyle changes are pivotal for the treatment of non-alcoholic fatty liver disease (NAFLD), and web-based programs might help remove barriers in both patients and therapists. METHODS: In the period 2010-15, 716 consecutive NAFLD cases (mean age, 52; type 2 diabetes, 33%) were treated in our Department with structured programs. The usual protocol included motivational interviewing and a group-based intervention (GBI), chaired by physicians, dietitians and psychologists (five weekly meetings, n = 438). Individuals who could not attend GBI entered a web-based intervention (WBI, n = 278) derived from GBI, with interactive games, learning tests, motivational tests, and mail contacts with the center. The primary outcome was weight loss >=10%; secondary outcomes were alanine aminotransferase within normal limits, changes in lifestyle, weight, alanine aminotransferase, and surrogate markers of steatosis and fibrosis. RESULTS: GBI and WBI cohorts had similar body mass index (mean, 33 kg/m2), with more males (67% vs. 45%), younger age, higher education, and more physical activity in the WBI group. The two-year attrition rate was higher in the WBI group. Healthy lifestyle changes were observed in both groups and body mass index decreased by almost two points;the 10% weight target was reached in 20% of WBI cases vs. 15% in GBI (not significant). In logistic regression analysis, after adjustment for confounders and attrition rates, WBI was not associated with a reduction of patients reaching short- and long-term 10% weight targets. Liver enzymes decreased in both groups, and normalized more frequently in WBI. Fatty liver index was reduced, whereas fibrosis remained stable (NAFLD fibrosis score) or similarly decreased (Fib-4). CONCLUSION: WBI is not less effective than common lifestyle programs, as measured by significant clinical outcomes associated with improved histological outcomes in NAFLD. eHealth programs may effectively contribute to NAFLD control. LAY SUMMARY: In patients with non-alcoholic fatty liver disease, participation in structured lifestyle programs may be jeopardized by job and time constraints. A web-based intervention may be better suited for young, busy patients, and for those living far from liver units. The study shows that, following a structured motivational approach, a web-based, interactive intervention coupled with six-month face-to face meetings is not inferior to a standard group-based intervention with respect to weight loss, adherence to healthy diet and habitual physical activity, normalization of liver enzymes, and stable surrogate markers of fibrosis. PMID- 30290974 TI - A network view on brain regions involved in experts' object and pattern recognition: Implications for the neural mechanisms of skilled visual perception. AB - Skilled visual object and pattern recognition form the basis of many everyday behaviours. The game of chess has often been used as a model case for studying how long-term experience aides in perceiving objects and their spatio-functional interrelations. Earlier research revealed two brain regions, posterior middle temporal gyrus (pMTG) and collateral sulcus (CoS), to be linked to chess experts' superior object and pattern recognition, respectively. Here we elucidated the brain networks these two expertise-related regions are embedded in, employing resting-state functional connectivity analysis and meta-analytic connectivity modelling with the BrainMap database. pMTG was preferentially connected with dorsal visual stream areas and a parieto-prefrontal network for action planning, while CoS was preferentially connected with posterior medial cortex and hippocampus, linked to scene perception, perspective-taking and navigation. Functional profiling using BrainMap meta-data revealed that pMTG was linked to semantic processing as well as inhibition and attention, while CoS was linked to face and shape perception as well as passive viewing. Our findings suggest that pMTG subserves skilled object recognition by mediating the link between object identity and object affordances, while CoS subserves skilled pattern recognition by linking the position of individual objects with typical spatio-functional layouts of their environment stored in memory. PMID- 30290975 TI - [High-risk neuroblastoma treatment strategy: The experience of the SIOPEN group]. AB - High-risk neuroblastoma comprises nearly half of cases of neuroblastoma and the long-term survival is less than 50% despite complex and intensive treatments. Studies conducted in Europe and in North America in the last two decades have identified a strategy based on four therapeutic phases: an intensive induction therapy, a local control by surgery and radiation, a consolidation phase with single or tandem high dose chemotherapy and autologous transplant, and immunotherapy to eliminate residual disease. Future treatment improvements are based on progress at each of these therapeutic steps and ultimately a better stratification of the strategy adapted to the type of risk. A more extensive tumor molecular profiling at diagnosis and relapse will help to develop new therapeutics and to guide risk-based strategies. Earlier use of immunotherapy and identification of more effective combinations in induction or in maintenance treatment, identification of indications of more intense consolidations using high-dose chemotherapy combined or not with metabolic irradiation by 131I-MIBG and the introduction of other targeted treatments are tracks being explored. PMID- 30290976 TI - Consumption of processed and pickled food and esophageal cancer risk: A systematic review and meta-analysis. AB - Previous investigations yielded inconsistent results for association of esophageal cancer (EC) risk and intake of processed food (including pickled food) or pickled food alone. The aim of this study was to perform a systematic review and meta-analysis of data exploring association of EC risk and intake of processed food (including pickled food) or pickled food alone. We systematically searched on PubMed and Web of Science for association of EC risk and intake of processed and pickled food published from 1964 to April 2018. We computed the multivariate odd ratio (OR) or relative risk (RR) and 95% confidence intervals (CI), comparing the highest and the lowest categories of processed or pickled food intake. The present meta-analysis showed that the highest categories of processed food intake were associated with a 78% increase in EC risk compared with the lowest categories. In addition, meta-analysis results indicated that the combined OR/RRs (95%CI) of studies comparing the highest and lowest categories were 2.10 (1.64-2.69) for pickled food. Subgroup study indicated significant positive associations between EC risk and intake of processed food or pickled food in case-control studies (combined ORs: processed food: 1.93 (95%CI: 1.66 2.24), pickled food: 2.28 (95%CI: 1.93-2.70)), whereas no significant associations were detected between them in cohort studies (combined RRs: processed food: 1.24 (95%CI: 0.98-1.58), pickled food: 1.43 (95%CI: 0.85-2.42)). In conclusion, this study suggests that both a high consumption of processed and pickled food may increase the EC risk. PMID- 30290977 TI - Reversible psychiatric adverse effects related to deep brain stimulation of the anterior thalamus in patients with refractory epilepsy. AB - OBJECTIVE: Anterior nucleus of thalamus (ANT) deep brain stimulation (DBS) is becoming a more common treatment for drug-resistant epilepsy. Epilepsy and depression display a bidirectional association. Anterior nucleus of thalamus has connections to anterior cingulate cortex and orbitomedial prefrontal cortex, hence, a possible role in emotional and executive functions, and thus, ANT DBS might exert psychiatric adverse effects. Our aim was to evaluate previous and current psychiatric symptoms in patients with epilepsy undergoing ANT DBS surgery and assess the predictability of psychiatric adverse effects. Programming-related psychiatric adverse effects are also reported. METHOD: Twenty-two patients with ANT DBS for retractable epilepsy were examined, and a psychiatric evaluation of depressive and other psychiatric symptoms was performed with Montgomery and Asberg Depression Rating Scale (MADRS), Beck Depression Inventory (BDI), and Symptom Checklist prior to surgery, concentrating on former and current psychiatric symptoms and medications. The follow-up visit was one year after surgery. RESULTS: At the group level, no changes on mood were observed during ANT DBS treatment. Two patients with former histories of depression experienced sudden depressive symptoms related to DBS programming settings; these were quickly alleviated after changing the stimulation parameters. In addition, two patients with no previous histories of psychosis gradually developed clear paranoid and anxiety symptoms that also relieved slowly after changing the programming settings. CONCLUSION: The majority of our ANT DBS patients did not experience psychiatric adverse effects. Certain DBS parameters might predispose to sudden depressive or slowly manifesting paranoid symptoms that are reversible via programming changes. PMID- 30290978 TI - Efficacy and Safety of Micropulse(r) Transscleral Cyclophotocoagulation in Glaucoma. AB - OBJECTIVE: To report the results using Micropulse(r) transscleral cyclophotocoagulation (Iridex) in the treatment of glaucoma. METHODS: Retrospective study in adult patients with glaucoma with at least 6 months of follow-up, and only one session of Micropulse(r). The same surgical technique was used in all cases. The only laser parameter that could vary was the total treatment duration (in seconds). The remaining parameters were fixed at 2 Watts of power and 0.5ms (31.3%) of active cycle. RESULTS: A total of 22 eyes of 17 patients with glaucoma of various types and stages were included (mainly congenital and pseudoexfoliation). The mean follow-up time was 7.9 months. The total treatment duration varied from 100 to 180seconds. Definition of success: 5mmHg =20% of the baseline value and no addition of oral carbonic anhydrase inhibitors, and no re-operation. The overall success rate was 72.7% in the first month, 54% at 4 months, 41% at 6 months, and 27.3% at final follow-up. Patients with longer treatment durations (180s) achieved better results. The mean reduction in IOP in successful eyes was 36% (from 26.3 to 16.7mmHg, SD 4.58, P=.028). No complications were reported. CONCLUSIONS: In a heterogeneous population of glaucoma (mostly congenital and pseudoexfoliation types), a low success rate (27.3%) was obtained in the medium term with a single session of Micropulse(r).

AB - PURPOSE: Routine human immunodeficiency virus (HIV) screening reduces HIV progression and transmission. Our aims were to determine prevalence and factors associated with prior HIV screening among a cohort of youth living with HIV. METHODS: Retrospective chart review of youth living with HIV aged 14-26 at an HIV clinic comparing characteristics between those with and without HIV screening within the year prior to diagnosis RESULTS: Subjects (n = 301) were male (85%), African-American (87%), and men who have sex with men (84%). Subjects seen 1 year prior to diagnosis (n = 58) contributed 179 visits for missed opportunities with 59% having a documented sexual history in the electronic health record and 48% tested for HIV. Subjects with symptoms suggesting acute HIV infection (51%) were more likely to be tested (p = .04). In the adjusted model, documentation of sexual history and demographic factors was not associated with prior testing. CONCLUSION: We identified high rates of missed opportunities for HIV testing and sexual history documentation in the year prior to diagnosis, underscoring the need for routine HIV screening in adolescents. PMID- 30290981 TI - Equivalent dose calculation in simulation of lung cancer treatment and analysis of dose distribution profile. AB - Currently, lung cancer is one of the most lethal types of cancer (IARC, 2012), the pathology being detected in advanced stage, when the tumor has considerable volume because the disease in most cases asymptomatic in the early stages (INCA, 2016). Dosimetry analysis of healthy organs under real conditions is not feasible. Therefore, computational simulations are used to aid in dose verification in organs of patients submitted to radiotherapy. The goal of this study was to calculate the equivalent dose, due to photons, in the surrounding of healthy organs of patients submitted to radiotherapy for lung cancer, through computational modeling. The simulation was performed using the MCNPX code (MNCPX, 2006), Rex and Regina phantoms (ICRP 110, 2009), radiotherapy room, Siemens Oncor Expression accelerator operating at 6 MV and treatment protocol adopted at the INCA (National Cancer Institute - Brazil). The results obtained, considering the dose due to photons for both phantoms indicate that organs located inside the thoracic cavity received higher dose, being the bronchi, heart and esophagus more affected, due to their anatomical positioning. Clinical data describe the development of bronchiolitis, esophagitis and cardiomyopathies with decreased cardiopulmonary function as one of the major effects of lung cancer treatment. In the Regina phantom, the second largest dose was in the region of the breasts with 615.73 mSv/Gy, while in the Rex the dose was 514.06 mSv/Gy, event related to the difference of anatomical structure of the organ. A qualitative analysis was performed between the dose deposition profile of the treatment planning system and the simulated treatment through the tmesh command and a similar profile of dose distribution was verified throughout the patient's body.

AB - Pyramidal neuron dendrites integrate synaptic input from multiple partners. Different inputs converging on the same dendrite have distinct structural and functional features, but the molecular mechanisms organizing input-specific properties are poorly understood. We identify the orphan receptor GPR158 as a binding partner for the heparan sulfate proteoglycan (HSPG) glypican 4 (GPC4). GPC4 is enriched on hippocampal granule cell axons (mossy fibers), whereas postsynaptic GPR158 is restricted to the proximal segment of CA3 apical dendrites receiving mossy fiber input. GPR158-induced presynaptic differentiation in contacting axons requires cell-surface GPC4 and the co-receptor LAR. Loss of GPR158 increases mossy fiber synapse density but disrupts bouton morphology, impairs ultrastructural organization of active zone and postsynaptic density, and reduces synaptic strength of this connection, while adjacent inputs on the same dendrite are unaffected. Our work identifies an input-specific HSPG-GPR158 interaction that selectively organizes synaptic architecture and function of developing mossy fiber-CA3 synapses in the hippocampus. PMID- 30290983 TI - Evaluation of Glucomannan Powder as an Ultrasound Transmission Gel Alternative for Resource-Constrained Environments: A Prospective, Comparative Study. AB - INTRODUCTION: Resource and logistical constraints may limit the availability of commercial ultrasound (US) transmission gel (USTG) in austere environments. Glucomannan powder, a dietary fiber supplement, can be mixed with tap water to form a gel that may be a field-expedient substitute for USTG. We compared glucomannan gel with a commercial USTG for US image adequacy and quality. METHODS: A single clinician obtained 193 US video clips from 14 different examinations on live-tissue and simulation training models using both commercial and glucomannan USTGs. Four US fellowship-trained providers, blinded to type of gel used, independently reviewed the randomized US video clips. The primary outcome of US image adequacy was scored as "yes" or "no" and analyzed using Pearson chi2 analysis. The secondary outcome of image quality was rated on a 0 to 5 Likert scale and analyzed with the independent t test. RESULTS: For US image adequacy, commercial USTG was superior to glucomannan gel (P=0.042, 95% CI: 96.5 96.6%), with commercial USTG adequate in 96.6% of images (375 of 388 "yes"), whereas glucomannan USTG was adequate in 93.5% (359 of 384 "yes") of images. For US image quality there was no statistically significant difference between the 2 USTGs (P=0.176, 95% CI: 93.4-93.5%), with commercial USTG rated at 3.4+/-1.0 and glucomannan gel at 3.3+/-1.1. CONCLUSION: Despite a high image adequacy rate, glucomannan gel proved inferior to commercial USTG for US image adequacy but produced equivalent image quality. Glucomannan USTG may be a reasonable substitute when commercial USTG is unavailable. PMID- 30290984 TI - Outcomes of left trisectionectomy and right hepatectomy for perihilar cholangiocarcinoma. AB - BACKGROUND: Right hepatectomy (RH) is the standard surgical procedure for perihilar cholangiocarcinoma (PHC) with right-sided predominance in many centers. Although left trisectionectomy (LT) is aggressively performed for PHC with left sided predominance in high-volume centers, the surgical and survival outcomes of LT are unclear. Therefore, this study aimed to compare the outcomes of LT and RH for PHC. METHODS: Consecutive patients who underwent surgical resection for PHC at Chiba University Hospital from 2008 to 2016 were retrospectively reviewed. The outcomes of patients with PHC who underwent LT were compared with those who underwent RH following one-to-one propensity score matching. RESULTS: Of 171 consecutive PHC resection patients, 111 were eligible for the study; 41 (37%) underwent LT, and 70 (63%) underwent RH. In a matched cohort (LT: n = 27, RH: n = 27), major complication rates (67% vs. 52%; p = 0.42), 90-day mortality rates (15% vs. 0%; p = 0.11) and R0 resection rates (56% vs. 44%; p = 0.58) were similar in both groups. The 3-year recurrence-free survival rates (27% vs. 47%; p = 0.27) and overall survival rates (45% vs. 60%; p = 0.17) were also similar in both groups. CONCLUSIONS: In patients with PHC, LT could achieve similar surgical and survival outcomes as RH. PMID- 30290985 TI - [Place of partial nephrectomy assisted by robot: Review of the literature at the time of a request for a specific nomenclature]. AB - INTRODUCTION: Robot-assisted surgery is practiced more and more frequently in urology. Besides its place in prostatectomy for cancer, it also concerns partial nephrectomy (NP), in the treatment of renal tumors. The objective of this review is to compare the robot-assisted approach with laparoscopic or open approaches in partial nephrectomy in terms of functional or oncological outcomes and per- and postoperative complications. MATERIAL AND METHODS: A systematic review of the literature published from 2009 was carried out on PubMed. Clinical studies or meta-analyzes comparing robot-assisted surgery versus laparoscopic or open surgery in the NP domain were used. RESULTS: The clinical data presented in this review of the literature are based mainly on meta-analyzes of comparative studies. Patients operated with robotic assistance (NPAR) had significantly fewer postoperative complications than patients operated by open (RR 0.61; P=0.0002) or laparoscopic surgery (RR 0.84; P=0.007). Positive margins, at equivalent pathological stages, are comparable to the open and appear to be lower than the laparoscopic surgery (RR 0.53; P<0.001). After NP, the change in postoperative glomerular filtration rate (GFR) appears to be identical between the 3 pathways. Hot ischemia time is significantly shorter for NPAR compared to NPL. Finally, the estimated blood loss and length of stay are less severe in patients operated by NPAR compared to those operated by open surgery. CONCLUSION: Robot-assisted surgery offers the same oncological results (in the short and medium term) and appears to improve functional outcomes and morbidity. However, these findings need to be carefully analyzed, due to the low level of evidence from the studies presented and included in the meta-analyzes, and the lack of randomized clinical studies. PMID- 30290986 TI - Professional advancement, performance, and injury characteristics of baseball players entering the Major League Baseball draft after treatment for shoulder injuries. AB - BACKGROUND: How shoulder injuries treated before the Major League Baseball (MLB) draft affect the player's performance over their career is unclear. The purpose of this study was to determine whether prior shoulder injuries were associated with a difference in the level of performance and advancement of MLB draftees. METHODS: Before entering the draft, 119 professional baseball players from 2004 to 2010 were treated for a shoulder injury (73% treated surgically) as an amateur. A 3:1 matched case-control was performed to players without prior shoulder injuries by age, position, round selected, and signing bonus. Follow-up data were collected in 2016, and professional advancement, disabled list time, and in-game performance statistics for pitchers were analyzed and compared. RESULTS: Players with a prior shoulder injury had a statistically higher chance to be assigned to the disabled list then controls (P = .03), but there was no difference in disabled list time or professional advancement. Pitchers with a prior shoulder injury pitched a statistically lower number of innings per game than controls (P = .04). All other in-game performance statistics were not statistically different. The type of treatment did not have any effect on future performance or advancement. CONCLUSIONS: Professional baseball players treated for prior shoulder injuries at the amateur level were more likely to sustain future disability than their matched controls, but it did not affect professional advancement.

AB - Btk is an attractive target for the treatment of a range of Bcell malignancies as well as several autoimmune diseases such as murine lupus and rheumatoid arthritis. Several covalent irreversible inhibitors of Btk are currently in development including ibrutinib which was approved for treatment of B-cell malignancies. Herein, we describe our efforts using X-ray guided structure based design (SBD) to identify a novel chemical series of covalent Btk inhibitors. The resulting pyridine carboxamides were potent and selective inhibitors of Btk having excellent enzymatic and cellular inhibitory activity. PMID- 30290989 TI - Ferrocene-based inhibitors of hepatitis C virus replication that target NS5A with low picomolar in vitro antiviral activity. AB - An unprecedented series of organometallic HCV (hepatitis C virus) NS5A (nonstructural 5A protein) replication complex inhibitors that incorporates a 1,1'-ferrocenediyl scaffold was explored. This scaffold introduces the elements of linear flexibility and non-planar topology that are unconventional for this class of inhibitors. Data from 2-D NMR spectroscopic analyses of these complexes in solution support an anti (unstacked) arrangement of the pharmacophoric groups. Several complexes demonstrate single-digit picomolar in vitro activity in an HCV genotype-1b replicon system. One complex to arise from this investigation (10a) exhibits exceptional picomolar activity against HCV genotype 1a and 1b replicons, low hepatocellular cytotoxicity, and good pharmacokinetic properties in rat. PMID- 30290990 TI - Low microRNA-139 expression associates with poor prognosis in patients with tumors: A meta-analysis. AB - BACKGROUND: microRNA-139 (miR-139) is dysregulated in various types of tumors and plays a key role in carcinogenesis. miR-139 may be used as a diagnostic and prognostic biomarker of cancers. However, the data from the literature are not consistent. The present study aimed to verify the prognostic and diagnostic values of miR-139 in solid tumors. DATA SOURCES: PubMed, Web of Science and Embase databases were searched and publications from January 2011 to August 2017 were included. We used Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) database to further validate this meta-analysis. RESULTS: Eight individual studies from seven articles were included. Pooled analyses showed that low miR 139 expression was related to worse overall survival (OS) [hazard ratio (HR) = 2.27; 95% confidence intervals (CI): 1.74-2.95; P < 0.001] in solid tumors, including hepatocellular carcinoma (HCC) and glioblastoma multiforme (GBM), consisting with the results of TCGA. However, our results of CRC showed that low miR-139 expression was associated with poor OS which was contradictory with the results in TCGA database and need larger samples to validate the phenomenon; whereas for CRC patients, high miR-139 expression predicted poor RFS, which was in good accordance with TCGA results. The results of 27 microarrays from GEO database showed that miR-139 expression levels were lower in tumor tissues compared to adjacent non-tumor tissues or healthy tissues. Decreased miR-139 expression was also significantly correlated with poor differentiation grade (OR = 3.57; 95% CI: 1.44-8.85; P = 0.006). However, the combined data indicated that no associations between miR-139 expression and the following parameters such as age (pooled OR = 1.50; 95% CI: 0.69-3.24; P = 0.304), gender (pooled OR = 0.92; 95% CI: 0.56-1.51; P = 0.738), tumor size (pooled OR = 1.51; 95% CI: 0.69-3.31; P = 0.298), late tumor-node-metastasis stage (pooled OR = 1.63; 95% CI: 0.99-2.68; P = 0.057) and lymph-node-metastasis (pooled OR = 0.66; 95% CI: 0.34-1.28; P = 0.222). CONCLUSIONS: Low miR-139 expression was related to poor prognosis in HCC and GBM, which could be regarded as a potential prognostic biomarker. However, its precise functional role in CRC still need to be further investigated through larger samples and multicenter studies. PMID- 30290991 TI - Roux-en-Y gastric bypass versus sleeve gastrectomy: what factors influence patient preference? AB - BACKGROUND: Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are the most commonly performed bariatric procedures. RYGB involves altered gastrointestinal anatomy and 2 anastomoses, while SG involves gastric resection. When potential patients view images of the procedures, they may perceive RYGB to involve significant risk compared with SG, in which no significant gastrointestinal alterations are depicted. OBJECTIVE: To evaluate preferences for RYGB versus SG. SETTING: Survey of U.S. adults. METHODS: An electronic survey was distributed to 1000 U.S. adults. Respondents selected either RYGB or SG based on (1) procedural pictures alone, (2) only data on risks and benefits of each procedure, (3) pictures with corresponding risk/benefit profile, and (4) pictures with mismatched information. RESULTS: Overall, 999 individuals met inclusion criteria; 66 (7%) had undergone bariatric surgery and were excluded. Mean age and body mass index of respondents was 44.8 +/- 14.6 years (n = 922) and 28.7 +/- 8.0 kg/m2 (n = 915). A higher proportion of patients preferred RYGB to SG when images only were provided (54% versus 46%), when information only was provided (63% versus 37%), and when correct information with the procedure image was provided (57% versus 43%). When presented with mismatched information and images, 56% preferred RYGB information + SG image versus SG information + RYGB image (44%). CONCLUSIONS: Based on this survey, providing evidence-based risks and benefits of a procedure resulted in the majority of respondents choosing RYGB over SG. When procedure images were provided alone, preference for RYGB and SG were similar. There are likely other factors contributing to increasing SG volume aside from patient preference. PMID- 30290992 TI - [Characteristics of patients of the Cerebral Palsy Association]. AB - INTRODUCTION: As the life expectancy has increased in individuals with cerebral palsy, this has led to being able to assess the changes in the bio-psycho-social dimensions of their health. OBJECTIVE: The aim of the study is to describe the characteristics of individuals with cerebral palsy and to evaluate their functional situation. METHODS: Cross-sectional descriptive study conducted on a sample of 26 individuals between 27 and 65 years old with cerebral palsy. Data was collected during a semi-structured interview. The Cross Motor Function Classification System (GMFCS), the Manual Ability Classification System (MACS), and the Communication Function Classification System (CFCS), were used to evaluate the functional situation. RESULTS: The profile of the adult seen in the Cerebral Palsy Association of Burgos, Spain, is male, over 40 years old, single, illiterate, with no professional qualification, lives in a residence, receives social benefit, and with great functional disability. CONCLUSIONS: The functional capacity of people with cerebral palsy who are in adult care centres is low. It emphasises the low cultural level and the lack of professional qualification and all of them have a disability that limits their ability to perform daily activities, possibly related to the high mean age.

PMID- 30290994 TI - Evaluation of benchtop NMR Diffusion Ordered Spectroscopy for small molecule mixture analysis. AB - Diffusion Ordered Spectroscopy (DOSY) is an attractive method for analyzing chemical mixtures in the liquid state because it separates spectra by the molecular weight of the associated molecule. It has been compared with hyphenated chromatographic and analytical methods such LC-MS and has broad potential in servicing those same applications including forensics, reaction analysis, quality control, and fraud detection. Benchtop NMR can collect quality spectra on small molecules, however, lacks the chemical shift dispersion of high field instruments, can suffer from spectral overlap common in mixtures, and the diminished sensitivity of the lower field compounds these problems. In this work, we show that existing high field pulse sequences and processing methods perform well at 43 MHz. Spectra from molecular mixtures where the constituents had 20% differences in diffusion coefficients and significant overlap were able to be matched to a bespoke spectral library and identified correctly. In addition, spectra from mixtures with constituents that have severe overlap in the spectrum and differ by 50% in diffusion coefficients were also able to be match and identified correctly. The combination of benchtop NMR and easy implementation of modern pulse sequences and processing show promise of bringing these useful methods to chemistry laboratories in research and industrial environments. PMID- 30290995 TI - T1-D-T2 correlation of porous media with compressed sensing at low-field NMR. AB - 3D Laplace NMR can distinguish different components of confined fluid in sedimentary rocks, which is important to oil industry. However, the measurement time for such experiments is very long, which hinders the application in some cases such as NMR well logging. In this research, we accelerated T1-D-T2 experiment with compressed sensing (CS) method at low-field NMR. Simulation was first performed to examine the CS reconstruction method. The experiments were subsequently implemented on a 2 MHz spectrometer (Oxford instrument), which has a similar magnetic field strength to well logging tool. The T1, D and T2 information are obtained by the inversion recovery, pulsed field gradients and Carr-Purcell-Meiboom-Gill (CPMG) method, respectively. The subsampling is applied in T1 and D dimensions with pseudo-random sampling. The measurement time reduced from 3 h to 0.6 h with CS method and a relative error of around 5% is achieved for data with signal-to-noise ratio of 28. The water and oil peaks are clearly distinguished in the correlation maps from subsampled data. The samples with different oil-water ratio and glass bead volume fraction were measured to examine the sensitivity of this method. In addition, diffusion and relaxation properties of the correlation maps are discussed. PMID- 30290996 TI - Perfluoroalkyl substances and metabolic syndrome. AB - BACKGROUND: Perfluoroalkyl substances (PFAS) are a class of contaminants used in many industrial applications and consumer products. Certain PFAS are regulated or voluntarily limited due to concern about environmental persistence and adverse health effects. OBJECTIVES: In this analysis we examine PFAS levels and their association with metabolic syndrome and its components, using a representative sample of the U.S. POPULATION: METHODS: Data on PFAS levels and metabolic syndrome components were collected from the 2007-2008, 2009-2010, 2011-2012, and 2013-2014 cycles of the National Health and Nutrition Examination Survey. Twelve different PFAS were measured in serum samples from participants. Logistic regression models were used to identify associations between metabolic syndrome, its individual components, and serum PFAS concentrations. RESULTS: Over one-third (37%) of participants met the definition for metabolic syndrome, with increased waist circumference and elevated glucose being the most commonly reported components. Seven PFAS were detected in at least 30% of participants and were examined in subsequent analyses (PFDA, PFOA, PFOS, PFHxS, MPAH, PFNA, PFUnDA). The PFAS with the highest concentrations was PFOS (median 8.4 ng/mL), followed by PFOA, PFHxS and PFNA. After adjusting for potential confounders, PFNA was associated with increased risk of metabolic syndrome and well as several individual components, while the highest levels of PFHxS were associated with elevated triglycerides. Other PFAS were associated with decreased risk of at least one outcome. CONCLUSIONS: Associations between PFAS and metabolic syndrome are inconsistent within and across studies. PFNA was consistently associated with increased risk for components of the syndrome, a finding that warrants further investigation. PMID- 30290997 TI - Relation between adenoid size and otitis media with effusion. AB - AIMS: This study compares the efficacy of adenoidectomy on otitis media with effusion (OME) in patients with different size of adenoids and the connection between differently sized adenoids and middle ear effusion. MATERIAL AND METHODS: Children with a history of at least 3 months' OME underwent adenoidectomy and myringotomy without the insertion of a tympanostomy tube. Treatment assignment was stratified by adenoids' size causing choanal obstruction (grade I-III) and according to Eustachian tube ostium obstruction (grade A-C). The subjects were followed for 12 months. RESULTS: Adenoidectomy was significantly more effective in children with adenoids in contact with torus tubarius (grade B, C) compared to those with small adenoids without contact (P<0.001). The volume of the adenoids was irrelevant (P=0.146). The size of adenoids did not affect the viscosity of the middle ear secretion. The distribution of mucous and serous secretion was not dependent on the size of adenoids; the efficacy of adenoidectomy was 82% in mucous as well as serous secretion. CONCLUSION: The relation between adenoids and torus tubarius is more important than the volume of the adenoids. The viscosity of middle ear fluids (serous or mucous) did not influence the rate of treatment efficacy. PMID- 30290998 TI - Comparison of cancer diagnosis recording between the Clinical Practice Research Datalink, Cancer Registry and Hospital Episodes Statistics. AB - INTRODUCTION: The Clinical Practice Research Datalink (CPRD) is a large electronic dataset of primary care medical records. For the purpose of epidemiological studies, it is necessary to ensure accuracy and completeness of cancer diagnoses in CPRD. METHOD: Cases included had a colorectal, oesophagogastric (OG), breast, prostate or lung cancer diagnosis recorded in a least one of CPRD, Cancer Registry (CR) or Hospital Episodes Statistics(HES) between 2000 and 2013. Agreement in diagnosis between the datasets, difference in dates, survival at one and five-years, and whether patient characteristics differed according to the dataset or the timing of diagnosis were investigated. RESULTS: 116,769 patients were included. For each cancer, approximately 10% of cases identified from CPRD or HES were not confirmed in the CR. 25.5% colorectal, 26.0% OG, 8.9% breast, 32.0% lung and 18.6% prostate cases identified from the CR were missing in CPRD. The diagnosis date was recorded later in CPRD compared with CR for each cancer, ranging from 81.1% for prostate to 59.6% for colorectal, especially if the diagnosis was an emergency. Compared with the CR and HES, the adjusted risk of a missing diagnosis in CPRD was significantly higher if the patient was older, had more co-morbidities or was diagnosed as an emergency. Survival at one and five-years was highest for CPRD. CONCLUSION: Patient demographics and the route of diagnosis impact the accuracy of cancer diagnosis in CPRD. Although CPRD provides invaluable primary care data, patients should ideally be identified from the CR to reduce bias. PMID- 30290999 TI - Surface lipidome of the lone star tick, Amblyomma americanum, provides leads on semiochemicals and lipid metabolism. AB - Lipids extracted from the surface of the lone star tick, Amblyomma americanum, were analyzed by high resolution mass spectrometry. Prior to lipid extraction, the adult ticks were either unfed or fed on cattle, and the fed ticks were in groups either containing males and females together, or containing only males or females. Cholesteryl esters were found on the surfaces of fed females, and they may provide a more complete description of the composition of the mounting sex pheromone. Dihydrocholesteryl esters were detected on the surfaces of unfed males and females, suggesting a possible role in survival during host-seeking. Dehydrodeoxyecdysone, found on fed females, could be a component of the genital sex pheromone. The most abundant polar surface lipids detected were acylglycerides. High levels of sphingolipids and glycerophospholipids on males fed separately might be derived, in part, from sperm development. A high level of a 20:4 fatty acid, presumably arachidonic acid, was found on the surface of fed females, indicating that it may be a component of the genital sex pheromone. A high level of docosenamide was found on the surface of fed females. Wax esters were found on the surfaces of fed ticks but not on unfed ticks. These esters could be involved in elasticity of the cuticle of engorged females or in wax coating of eggs. N-acylethanolamines were found on the surfaces of male and female ticks fed together, and on male ticks fed separately, but were absent or at low levels on females fed separately and on unfed ticks. This pattern suggests a possible role as a metabolic coordination primer pheromone. PMID- 30291000 TI - Remote Viewing of Concealed Target Pictures Under Light and Dark Conditions. AB - CONTEXT: The belief that performing a nonlocal task in darkness plays a facilitating role in remote viewing and other psi-related phenomena is well established in esoteric and traditional beliefs (Grim, 1983; Hallowell, 1942; Lyon, 2012). However, the role of darkness in RV success is unclear beyond these esoteric explanations. OBJECTIVE: This study explored the differential effect of darkness/light on remote viewing ability alongside the effect of time and their potential interaction. DESIGN: From an initial sample of twenty, seven remote viewers contributed a total of nineteen sessions each (nine light/ten dark) which utilised randomized target selection, free-response descriptions, and ratings by both participants and an independent judge. RESULTS: The usable data gave the edge to dark condition performance; the difference was not statistically significant. A statistically significant difference between remote viewer and independent judge raw scores attributed to the target image was identified (t (132) = 4.56, p <.001 (two-tailed) Mdiff = 14.21 [8.05, 20.4]) with a medium effect size (d = 0.40 [0.21, 0.57]). Exploratory post-hoc analyses concerning the numinosity of target images were conducted, to determine if this characteristic was associated with success. For numinosity ratings of target images, a mean difference of 11.24, 95% CI [0.12, 22.3] was shown as significant, with the target images of participant 'hit' sessions containing higher numinosity ratings than unsuccessful 'miss' sessions (t (11.47) = 2.22, p (two-tailed) = .048) with a large effect size (d = 1.02, [0.01, 1.99]). CONCLUSION: The findings may have implications for the use of participant judgments in future remote viewing research. Furthermore, because there are several advantages to what parapsychologists refer to as "free response" targets as opposed to "forced choice" targets (Honorton, 1975), the findings for target numinosity may have implications for the future selection of target material. PMID- 30291001 TI - Are self-ligating brackets' slots dimensions accurate? AB - OBJECTIVE: The purpose of this study is to measure the dimensions of the slot's top and base of passive self-ligating brackets of three commercial and available systems and to compare the measured dimensions with the manufacturers' published dimensions. METHODS: Digital microscope was used to measure the slot's top and base of 40 Central incisor brackets by three different manufacturers, Carriere SLX (Ortho Organizer, USA), Damon Q (Oramco USA) and Smart Clip (3M Unitek USA). The measurements were taken after the doors of all brackets were removed and compared with the manufacturers' claimed dimensions. RESULTS: All brackets showed a significant increase in dimensions from both the slot's top and base compared to the manufacturers' published dimensions. For the base of the bracket's slot, Carriere SLX brackets showed the least difference while Damon Q brackets had the greatest. Moreover, for the top of the bracket's slot, the Smart clip brackets showed the greatest difference. The percentage of difference between the actual measurements and the manufacturers' prescriptions shows that for the slot's base, Carriere SLX brackets had the smallest percentage increase by .36%, followed by Smart clip by 6.7% and the Damon Q brackets by 8.1%. While for the slot's top Carriere SLX had the smallest percentage increase by .72%, followed by Damon Q by 12.3% increase and finally Smart Clip brackets by 12.8%. CONCLUSIONS: The actual measurements of passive self-ligating brackets from 3 manufacturers were larger than the manufacturers' published dimension. This amount of increase may affect the amount torque expression. PMID- 30291002 TI - ? PMID- 30291003 TI - Efficiency of colony formation and differentiation of human spermatogenic cells in two different culture systems. AB - Optimization of in vitro culture system for the expansion and the maturation of male germ cells to post meiotic stages is a valuable tool for studies exploring spermatogenesis regulation and the management of male infertility. Several studies have reported promising results of mouse spermatogonial stem cells culture in three-dimensional (3D) culture systems and a subsequent production of sperm. In the present study, we investigated the capacity of a three-dimensional soft agar culture system (SACS) supplemented with Knockout Serum Replacement (KSR) in colony formation and inducing human germ cells to reach post-meiotic stages. Testicular cells from testes of brain -dead donors were first cultured for three weeks in proliferation medium. The cells were subsequently cultured in the upper layer of the SACS (3D group) in a medium supplemented with KSR and hormones, and the results were compared with that of a two-dimensional (2D) culture system. We found that the number and diameter of colonies and the levels of expression of Scp3 and Integrin alpha6 in the 3D culture group were significantly higher than in the 2D group. Our findings indicate that SACS can reconstruct a microenvironment capable of regulating both proliferation and differentiation of cell colonies. PMID- 30291004 TI - The role of network ties to support implementation of a community pharmacy enhanced services network. AB - BACKGROUND: Limited evidence exists on how to integrate community pharmacists into team-based care models, as the inclusion of community pharmacy services into alternative payment models is relatively new. To be successful in team-based care models, community pharmacies need to successfully build relationship with diverse stakeholders including providers, care managers, and patients. OBJECTIVES: The aims of this study are to: (1) identify the role of network ties to support implementation of a community pharmacy enhanced services network, (2) describe how these network ties are formed and maintained, and (3) compare the role of network ties among high- and low-performing community pharmacies participating in an enhanced services network. METHODS: Using a semi-structured interview guide, we interviewed 40 community pharmacy representatives responsible for implementation of a community pharmacy enhanced services program. We analyzed for themes using social network theory to compare network ties among 24 high- and 16 low-performing community pharmacies. RESULTS: The study found that high performing pharmacies had a greater diversity of network ties (e.g., relationships with healthcare providers, care managers, and public health agencies). High-performing pharmacies were able to use those ties to support implementation of NC-CPESN. High- and low-performing pharmacies used similar strategies for establishing ties with patients, such as motivational interviewing and assigning staff members to be responsible for engaging high-risk patients. High-performing pharmacies used additional strategies such as assessing patient preferences to support patient engagement, increasing patient receptivity towards enhanced services. CONCLUSIONS: Community pharmacies may vary in their ability to develop relationships with other healthcare providers, care management and public agencies, and patients. As enhanced services interventions that require care coordination are scaled up and spread, additional research is needed to test implementation strategies that support community pharmacies with developing and maintaining relationships across a diverse group of stakeholders (e.g., healthcare providers, care managers, public health agencies, patients). PMID- 30291005 TI - Dentofacial deformities and the quality of life of patients with these conditions: a comparative study. AB - OBJECTIVES: The aim of the present study was to evaluate the quality of life of patients with dentofacial deformities and of patients subjected to orthognathic surgery to compare their results with those of patients who have no dentofacial deformity by applying the Orthognathic Quality of Life Questionnaire (OQLQ). STUDY DESIGN: Three groups of patients were interviewed, and the OQLQ instrument was applied to them by one examiner. RESULTS: Results showed statistical differences between groups and suggested that patients with no deformity and those subjected to orthognathic surgery have better quality of life compared with those with facial deformity. CONCLUSIONS: Orthognathic surgery with the consequent dentofacial correction seems to have a positive effect on quality of life. PMID- 30291006 TI - Multiple superficial mucoceles concomitant with oral lichen planus: a case series. AB - Superficial mucoceles are a relatively rare variant of common mucoceles and have an unclear etiology. Clinically, they are small, translucent, subepithelial vesicles affecting the oral mucosa in the retromolar region, the lower labial and buccal regions, and the bilateral soft palate. Superficial mucocele is easily misdiagnosed as pemphigoid, bullous lichen planus, herpes lesion, or venous lake when it is concomitant with oral lichen planus (OLP) or lichenoid disorders on the basis of the initial impression. An inflammatory mechanism related to OLP has been hypothesized to induce the development of superficial mucoceles. It is essential to be familiar with this entity. This report presents 9 cases of multiple superficial mucoceles that occurred sequentially concomitant with OLP and with consistent clinical and histopathologic features. Relevant studies reported in the literature are also reviewed to provide additional clarification of the etiology, clinicopathologic characteristics, and differential diagnosis. PMID- 30291007 TI - A clinicopathologic study on central odontogenic fibroma: with special reference to amyloid variant. AB - OBJECTIVE: The aim of this study was to clarify the clinicopathologic features of central odontogenic fibroma (OF), especially the amyloid variant, and to discuss its association with the Langerhans cell variant of calcifying epithelial odontogenic tumor (CEOT). STUDY DESIGN: The clinicopathologic features and immunophenotypes of 17 OFs, including 6 amyloid variants, were analyzed. The Langerhans cell variant of CEOT is reviewed, and its relationship with OF is discussed. RESULTS: Most OFs (13 of 17) were located at the anterior region of the jaws, often with root resorption. The amyloid variant exhibited the typical clinicopathologic features of OFs, characterized by dispersed small epithelial nests embedded in a fibrous stroma. Immunohistochemically, the epithelial component in all central OFs, including the amyloid variants, exhibited dispersed staining for CK10/13 but was negative for CK7 and CK8/18. Langerhans cells were positive for S-100 and Langerin in the epithelium of OFs, including the amyloid variants. CONCLUSIONS: The amyloid variant of OF is a rare benign tumor exhibiting the typical clinicopathologic features of conventional OFs and should not be diagnosed as CEOT even in the presence of amyloid deposits. Previously reported cases described as "Langerhans cell variant of CEOT" should be classified as the "amyloid variant of OF," given that it shares features more in common with OFs than with CEOTs. PMID- 30291008 TI - One-year risks of stroke and mortality in patients with atrial fibrillation from different clinical settings: The Gulf SAFE registry and Darlington AF registry. AB - BACKGROUND: Differences exist in oral anticoagulation (OAC) use between different populations with atrial fibrillation (AF), which may be associated with varying outcomes. PURPOSE: We aimed to provide patient level comparisons of two cohorts of patients with AF, from the United Kingdom (UK) and Middle East (ME). METHODS: The clinical characteristics, prescription of OAC, one-year risk of stroke and mortality were compared between individual patients with AF included into the Darlington AF registry (UK, n = 2258) and the Gulf SAFE (Survey of atrial fibrillation events) registry (ME, n = 1740). RESULTS: A high percentage of patients from the Darlington registry were candidates for OAC (i.e., CHA2DS2-VASc score >=2 in males or >=3 in females; 82.0% in Darlington and 57.1% in Gulf SAFE). OAC use was suboptimal (52.0% in Darlington vs 58.4% in Gulf SAFE). One year rates of stroke and mortality were high in both populations, especially in those with CHA2DS2-VASc score >=2 in males and >=3 in females (Darlington vs. Gulf SAFE: 3.51% vs. 5.63 for stroke; 11.4% vs. 16.8% for mortality). On multivariate analyses, female sex and previous stroke were independently associated with stroke events; while elderly age, female sex, vascular disease and heart failure were independent risk factors for mortality (all p < 0.05). Patients from Gulf SAFE registry had higher risk of stroke (odds ratio, 2.18 [1.47-3.23]) and mortality (odds ratio, 1.67 [1.31-2.14]) compared with those from Darlington registry. The CHA2DS2-VASc score showed good discrimination in predicting one-year risk of stroke (area under curve, 0.71 [0.65-0.76] in non anticoagulated patients) and mortality (area under curve, 0.70 [0.68-0.72]) in the whole study population, as well as in Darlington or Gulf SAFE registry separately. CONCLUSIONS: Stroke prevention was generally suboptimal in patient cohorts from the two registries, which was associated with high one-year risks of stroke and mortality, particularly so among patients from the Gulf SAFE registry. The higher risks for stroke and mortality in AF patients from the Gulf SAFE registry (compared to a UK cohort) merit further implementation of cardiovascular prevention strategies. PMID- 30291009 TI - Centrifugal wave-front propagation speed for localizing the atrial tachycardia origin. AB - BACKGROUND: The earliest activation site (EAS) on a centrifugally-propagated atrial tachycardia (AT) map may represent the true AT origin (true-focal pattern), or the earliest site resulting from passive activation of AT originating from neighboring tissue (pseudo-focal pattern). We assessed the benefits of using the wave-front propagation speed to distinguish between the true- and the pseudo-focal pattern. METHODS: AT mapping was performed using a novel ultra-high resolution mapping system with a 64-electrode mini-basket catheter. The true AT origin was defined as the site where radiofrequency application eliminated AT. The wave-front propagation speed was estimated from the area surrounded by the centrifugally-propagated wave front over a specific time interval. RESULTS: Total of 46 centrifugally propagated AT maps from 34 patients were analyzed, including 18 true-focal and 28 pseudo-focal pattern. The area surrounded by the propagated wave front was significantly smaller for the true-focal pattern than for the pseudo-focal pattern, 1-20 msec after the earliest activation. The true-focal pattern was identified by the area 13 msec after the earliest activation, with the best cut-off area value of <4.5 cm2. CONCLUSION: The presence or absence of a true origin of AT at the EAS on centrifugally-propagated AT maps can be distinguished using a wave-front propagation speed. PMID- 30291010 TI - Duration and complications of diabetes mellitus and the associated risk of infective endocarditis. AB - BACKGROUND: Long duration of diabetes mellitus (DM) is associated with an increased risk of infection, however no studies have yet focused on the duration of DM and the associated risk of infective endocarditis (IE). METHODS: Patients with DM were identified through the Danish Prescription Registry, 1996-2015. Duration of DM was split in follow-up periods of: 0-5 years, 5-10 years, 10-15 years, and >15 years. Multivariable adjusted Poisson regression was used to calculate incidence rate ratios (IRR) according to study groups. DM late-stage complications and the associated risk of IE were investigated as time-varying covariates using the validated Diabetes Complications Severity Index (DCSI). RESULTS: We included 299,551 patients with DM. In patients with DM duration of 0 5 years, 5-10 years, 10-15 years, and >15 years, the incidence rates of IE were 0.24, 0.33, 0.58, and 0.96 cases of IE/1000 person years, respectively. Patients with DM duration 5-10 years, 10-15 years, and >15 years were associated with a higher risk of IE with an IRR of 1.24 (95% CI: 1.02-1.51), 1.92 (95% CI: 1.52 2.43) and 3.05 (95% CI: 2.11-4.40), respectively, compared with DM duration 0-5 years. Patients with a DCSI score of 2, 3 and >3 were associated with a higher risk of IE compared with patients with a DCSI score of 0, IRR = 1.78 (95% CI: 1.34-2.36), IRR = 2.34 (95% CI: 1.73-3.16), and IRR = 2.59 (95% CI: 1.92-3.48), respectively. CONCLUSION: This study shows a stepwise increase in the risk of IE with DM duration and severity independent of age and known comorbidity. PMID- 30291011 TI - Effect of Intensive Blood Pressure Lowering on Kidney Tubule Injury: Findings From the ACCORD Trial Study Participants. AB - RATIONALE & OBJECTIVE: Random assignment to intensive blood pressure (BP) lowering (systolic BP<120mmHg) compared to a less intensive BP target (systolic BP<140mmHg) in the Action to Control Cardiovascular Risk in Diabetes BP (ACCORD BP) trial resulted in a more rapid decline in estimated glomerular filtration rate (eGFR). Whether this reflects hemodynamic effects or intrinsic kidney damage is unknown. STUDY DESIGN: Longitudinal analysis of a subgroup of clinical trial participants. SETTINGS & PARTICIPANTS: A subgroup of 529 participants in ACCORD BP. EXPOSURES: Urine biomarkers of tubular injury (kidney injury molecule 1, interleukin 18 [IL-18]), repair (human cartilage glycoprotein 39 [YKL-40]), and inflammation (monocyte chemoattractant protein 1) at baseline and year 2. OUTCOMES: Changes in eGFR from baseline to 2 years. ANALYTICAL APPROACH: We compared changes in biomarker levels and eGFRs across participants treated to an intensive versus less intensive BP goal using analysis of covariance. RESULTS: Of 529 participants, 260 had been randomly assigned to the intensive and 269 to the standard BP arm. Mean age was 62+/-6.5 years and eGFR was 90mL/min/1.73m2. Baseline clinical characteristics, eGFRs, urinary albumin-creatinine ratios (ACRs), and urinary biomarker levels were similar across BP treatment groups. Compared to less intensive BP treatment, eGFR was 9.2mL/min/1.73m2 lower in the intensive BP treatment group at year 2. Despite the eGFR reduction, within this treatment group, ACR was 30% lower and 4 urinary biomarker levels were unchanged or lower at year 2. Also within this group, participants with the largest declines in eGFRs had greater reductions in urinary IL-18 and YKL-40 levels. In a subgroup analysis of participants developing incident chronic kidney disease (sustained 30% decline and eGFR<60mL/min/1.73m2; n=77), neither ACR nor 4 biomarker levels increased in the intensive treatment group, whereas the level of 1 biomarker, IL-18, increased in the less intensive treatment group. LIMITATIONS: Few participants with advanced baseline chronic kidney disease. Comparisons across treatment groups do not represent comparisons of treatment arms created solely through randomization. CONCLUSIONS: Among a subset of ACCORD-BP trial participants, intensive BP control was associated with reductions in eGFRs, but not with an increase in injury marker levels. These findings support that eGFR decline observed with intensive BP goals in ACCORD participants may predominantly reflect hemodynamic alterations. PMID- 30291012 TI - Effects of Intensive Blood Pressure Lowering on Kidney Tubule Injury in CKD: A Longitudinal Subgroup Analysis in SPRINT. AB - BACKGROUND: Random assignment to the intensive systolic blood pressure (SBP) arm (<120mmHg) in the Systolic Blood Pressure Intervention Trial (SPRINT) resulted in more rapid declines in estimated glomerular filtration rates (eGFRs) than in the standard arm (SBP<140mmHg). Whether this change reflects hemodynamic effects or accelerated intrinsic kidney damage is unknown. STUDY DESIGN: Longitudinal subgroup analysis of clinical trial participants. SETTINGS & PARTICIPANTS: Random sample of SPRINT participants with prevalent chronic kidney disease (CKD) defined as eGFR<60mL/min/1.73m2 by the CKD-EPI (CKD Epidemiology Collaboration) creatinine-cystatin C equation at baseline. OUTCOMES & MEASUREMENTS: Urine biomarkers of tubule function (beta2-microglobulin [B2M], alpha1-microglobulin [A1M]), and uromodulin), injury (interleukin 18, kidney injury molecule 1, and neutrophil gelatinase-associated lipocalin), inflammation (monocyte chemoattractant protein 1), and repair (human cartilage glycoprotein 40) at baseline, year 1, and year 4. Biomarkers were indexed to urine creatinine concentration and changes between arms were evaluated using mixed-effects linear models and an intention-to-treat approach. RESULTS: 978 SPRINT participants (519 in the intensive and 459 in the standard arm) with prevalent CKD were included. Mean age was 72+/-9 years and eGFR was 46.1+/-9.4mL/min/1.73m2 at baseline. Clinical characteristics, eGFR, urinary albumin-creatinine ratio, and all 8 biomarker values were similar across arms at baseline. Compared to the standard arm, eGFR was lower by 2.9 and 3.3mL/min/1.73m2 in the intensive arm at year 1 and year 4. None of the 8 tubule marker levels was higher in the intensive arm compared to the standard arm at year 1 or year 4. Two tubule function markers (B2M and A1M) were 29% (95% CI, 10%-43%) and 24% (95% CI, 10%-36%) lower at year 1 in the intensive versus standard arm, respectively. LIMITATIONS: Exclusion of persons with diabetes, and few participants had advanced CKD. CONCLUSIONS: Among participants with CKD in SPRINT, random assignment to the intensive SBP arm did not increase any levels of 8 urine biomarkers of tubule cell damage despite loss of eGFR. These findings support the hypothesis that eGFR declines in the intensive arm of SPRINT predominantly reflect hemodynamic changes rather than intrinsic damage to kidney tubule cells.

PMID- 30291016 TI - Findings From a Randomized Trial of Weight Gain Prevention Among Overweight Puerto Rican Young Adults. AB - OBJECTIVE: Assess impact of multimodality weight gain prevention intervention. METHODS: Randomized clinical trial among 39 overweight young Puerto Rico college students using 10 weekly peer-support sessions promoting dietary, physical activity, and other lifestyle changes enhanced by stress-reduction and mindfulness approaches. Body mass index (BMI) and self-reported behaviors were measured at baseline and at 10 weeks and 6 months after baseline. RESULTS: At the completion of the intervention, BMIs in the experimental arm were 0.8 units lower than at baseline (z = -3.0; P = .008) and 1.2 lower at 6 months after baseline (z = -4.1; P < .001); BMIs in the control arm were 0.7 higher (z = 2.7; P = .02) at 10 weeks and 0.8 higher at 6 months (z = 3.1; P = .005). Group * time interaction confirmed that BMI differed significantly over time between arms (chi2 = 26.9; degrees of freedom = 2; P < .001). Analysis of behavioral changes was mostly inconclusive although the experimental arm reported a considerable increase in walking at 10 weeks. Qualitative data suggested that yoga and mindfulness components were particularly useful for motivating participants to maintain healthier lifestyle patterns. CONCLUSIONS: Body mass index in the experimental arm decreased at the end of intervention and was maintained at 6 months' follow up. PMID- 30291017 TI - Adjusted Citation Rate, an Alternative Metric to Measure the Impact of General Radiology Journals. AB - RATIONALE AND OBJECTIVES: The journal impact factor (JIF) is often used to assess the prestige of scientific journals. Citations from original articles and reviews as well as citations from noncitable items contribute to the numerator in these calculations. However, since noncitable articles are not included in the denominator, the JIF may be skewed by the types of articles and not accurately reflect the prestige of the journal. The purpose of our study was to develop an alternative and complementary metric by which journals may be assessed. This "adjusted citation rate metric" is based on citations that originate only from citable items in the journal. MATERIAL AND METHODS: We tabulated the number of citations and citable items for original articles from the Web of Science Core Collection for 5 consecutive years (2010-2014) for 20 general radiology journals. The adjusted citation rates (CR) per original article and reviews were calculated using only citations that originated from citable items. RESULTS: The adjusted CR in 2015 was similar to the JIF in 14 of the 20 journals, higher in four journals, and lower in two journals. Using this system, Radiology, Investigative Radiology, and European Radiology remained first, second, and third respectively among journals published in the field of general radiology. To allow for equal distribution of original articles vs reviews among general radiology journals, we calculated the adjusted CR where the standard distribution of original articles is 50%. CONCLUSION: Adjusted citation rate is an objective index for assessing journal impact that can serve as an alternative and complementary metric with which to measure the journal impact. PMID- 30291018 TI - Comorbid hypertension and diabetes among U.S. women of reproductive age: Prevalence and disparities. AB - AIMS: Diabetes is associated with significant pregnancy complications, which can be further exacerbated by comorbid hypertension. Racial/ethnic differentials in the burden of comorbid hypertension and diabetes among women of reproductive age have not been described. METHODS: Using Wave IV of the nationally representative National Longitudinal Study of Adolescent to Adult Health (Add Health), we analyzed survey and biological data from 6576 non-pregnant women who were aged 24 32 in 2007-2008. Hypertension and diabetes were identified by self-report of diagnosis and biological measurements taken during in-home interviews. We used logistic regression models to predict the presence of comorbid hypertension and diabetes and whether each was diagnosed. RESULTS: Over a third (36.0%) of women with diabetes had comorbid hypertension. Compared to non-Hispanic white women, more non-Hispanic black women had comorbid hypertension and diabetes (adjusted odds ratio (aOR) 5.93, 95% CI 3.84-9.16), and, if comorbid, were less likely to have a diabetes diagnosis (aOR 0.03, 95% CI 0.007-0.1) or hypertension diagnosis (aOR 0.22, 95% CI 0.08-0.65). CONCLUSION: Comorbid hypertension and diabetes are more common among non-Hispanic black women and less likely to be diagnosed, signaling disparities threatening maternal and child health among women with diabetes. PMID- 30291019 TI - Risk of Serious Bacterial Infection in Infants Aged <=60 Days Presenting to Emergency Departments with a History of Fever Only. AB - OBJECTIVE: To compare the risk of serious bacterial infection between infants aged <=60 days who are febrile in the emergency department (ED) and those who have only a history of fever and are afebrile on arrival to the ED. STUDY DESIGN: In this secondary analysis of a multicenter prospective study using data collected between December 2008 and May 2013, we compared the rate of serious bacterial infection (urinary tract infection [UTI], bacteremia, and/or bacterial meningitis) between infants who have a history of fever but are afebrile on arrival to the ED and those with fever documented in the ED (rectal temperature >=38.0 degrees C) using relative risk (RR) with 95% CI. Stratified analyses were performed for age (<=28 and 29-60 days) and serious bacterial infection type. Infants born prematurely and those with a clinical focal infection or serious illness were excluded. RESULTS: A total of 3825 infants (mean age, 35.2 days; 56.9% male) were included. Of the 1233 (32.2%) who were afebrile in the ED, 108 (8.8%) had a serious bacterial infection (UTI, n = 94 [7.6%]; bacteremia, n = 19 [1.5%]; bacterial meningitis, n = 8 [0.6%]). Of the 2592 infants (67.8%) who were febrile in the ED, 331 (12.8%) had a serious bacterial infection (UTI, n = 285 [11.0%]; bacteremia, n = 61 [2.4%]; bacterial meningitis, n = 17 [0.7%]). The RR for serious bacterial infection for afebrile vs febrile infants was 0.68 (95% CI, 0.56-0.84). A lower risk of serious bacterial infection was also seen among afebrile vs febrile infants aged <=28 days (RR, 0.69; 95% CI, 0.52-0.93) and age 29-60 days (RR, 0.67; 95% CI, 0.50-0.89). CONCLUSIONS: The prevalence of serious bacterial infection is lower in infants aged <=60 days with a history of fever compared with those who are febrile on arrival to the ED. The small risk reduction in this group is unlikely to alter decision making. PMID- 30291020 TI - Prognostic Factors and Management of Patients with Choanal Atresia. AB - OBJECTIVE: To analyze prognostic factors in the management of patients with choanal atresia. STUDY DESIGN: This is a review of 114 patients operated on for choanal atresia in a tertiary care center between November 1986 and November 2016, including clinical characteristics, surgical management, and postoperative course with final nasal patency. The data were collected in a database that was updated over time. RESULTS: Among the 114 patients, 78 were female, 77 presented with unilateral choanal atresia, and 37 presented with bilateral unilateral choanal atresia, corresponding to 151 nasal fossae. Forty-seven patients had associated abnormalities (41.2%), including CHARGE, diagnosed in 20 children (17.5%). At the end of follow-up, 91 patients (79.8%) had normal choanal patency. The identified risk factors of surgical failure were age <6 months (P = .004), weight <5 kg (P = .007), and bilateral choanal atresia (P < .001). The type of atresia, presence of associated abnormalities, surgical approach, stenting, and use of mitomycin were not significantly linked with the surgical results. CONCLUSIONS: This series highlights the importance of the timing of surgery, which is guided by the clinical ability of the infant to tolerate the procedure. Endoscopic approaches are widely performed, but a transpalatal approach, necessary in some cases of bilateral choanal atresia, does not alter the results. Unilateral choanal atresia surgery should be delayed after age 6 months and/or weight >5 kg when possible. PMID- 30291021 TI - Parent Perspectives on Readiness for Discharge Home after Neonatal Intensive Care Unit Admission. AB - OBJECTIVE: To explore the parent perspective on discharge home from the neonatal intensive care unit (NICU). STUDY DESIGN: We interviewed parents of NICU graduates with a range of demographic characteristics and medical complexities to explore parent perspectives on readiness for discharge. Interviews were transcribed and coded by a 6-member team. We performed content analysis to identify themes and develop a family-centered conceptual framework around readiness for NICU discharge. RESULTS: We interviewed a total of 15 parents who experienced NICU stays with 18 infants. Parents who have experienced NICU discharge have a spectrum of needs that evolve from the time the child is in the NICU, at time of discharge, and at home afterward. These needs consistently centered around 5 themes-communication, parent role clarity, emotional support, knowledge sources, and financial resources. CONCLUSIONS: Parents described many ways the system could have better prepared them and connected them with essential resources. Summarizing the voices of the parents who participated in this study, we have compiled a series of practical recommendations for clinicians to use in daily practice to help parents feel prepared and confident for the transition home from the NICU. PMID- 30291022 TI - Long-Term Cardiovascular Morbidity in Children Born Following Fertility Treatment. AB - OBJECTIVE: To determine the risk of long-term cardiovascular disease (CVD) among children born following in vitro fertilization (IVF) and compared with spontaneous pregnancies. STUDY DESIGN: A population-based cohort study including all singleton deliveries occurring between 1991and 2014 at a tertiary medical center was performed. Hospitalizations up to the age of 18 years involving CVD were evaluated in children delivered following IVF, ovulation induction, and spontaneous pregnancies. CVD included valvular disorders, hypertension, arrhythmias, rheumatic disease, cardiomyopathy, ischemic heart disease, and heart failure. Kaplan-Meier survival curves were used to compare cumulative morbidity incidence, and a Cox regression model controlled for confounders. RESULTS: During the study period, 242 187 singleton deliveries met the inclusion criteria; 1.1% following IVF (n = 2603), and 0.7% following ovulation induction (n = 1721). Hospitalizations up to the age of 18 years involving CVD (n = 1503) were comparable in children delivered following IVF (0.6%), ovulation induction (0.7%), and spontaneous pregnancies (0.6%; P = .884). No significant difference in the cumulative incidence of CVD was noted between the groups (log rank P = .781). Controlling for maternal age, gestational age, birthweight, maternal diabetes, and hypertensive disorders in pregnancy, fertility treatment was not noted as a risk factor for long-term pediatric CVD (IVF adjusted hazard ratio 1.05, 95% CI 0.63-1.74, P = .86; ovulation induction adjusted hazard ratio 0.97, CI 95% 0.55-1.71, P = .92). CONCLUSIONS: Singletons conceived via fertility treatments do not appear to be at an increased risk of long-term pediatric CVD.

PMID- 30291024 TI - Prostaglandin E-major urinary metabolite as a noninvasive surrogate marker for infantile necrotizing enterocolitis. AB - BACKGROUND: Early definitive diagnosis of necrotizing enterocolitis (NEC) based on Bell's staging criteria is difficult because there are few observable changes on abdominal imaging and blood chemistry tests at the onset of the disease. PURPOSE: To investigate whether prostaglandin E-2 major urinary metabolite (PGE MUM) can be a useful surrogate marker reflecting the disease state and severity of NEC in infants. METHODS: Infants were enrolled in this study between January 2014 and December 2016. NEC diagnosis was based on Bell's staging criteria > Stage II or necrotic bowel observed at surgery. After diagnosis, PGE-MUM level was measured and compared with that of the other disease and healthy infant groups. RESULTS: Median PGE-MUM value was highest in the NEC group (576 [65-3672] MUg/g*Cre/BSA * 1000), followed by the other disease group (94 [57-296] MUg/g*Cre/BSA * 1000) and the healthy infant group (19 [10-44] MUg/g*Cre/BSA * 1000) (sensitivity: 92.3%, specificity: 81.5%, accuracy: 85.0%; p < 0.01). PGE MUM level correlated with improved status of NEC, length of necrotic intestine, and Bell's staging criteria. CONCLUSIONS: PGE-MUM level may be a useful surrogate biomarker reflecting the disease state of NEC. The method of urine sample collection is also advantageous, being noninvasive for infants. This is the first study reporting PGE-MUM level in NEC. TYPE OF STUDY: Study of diagnostic test. LEVEL OF EVIDENCE: LEVEL II. PMID- 30291025 TI - Distribution, diagnosis, and treatment of pulmonary sequestration: Report of 208 cases. AB - OBJECTIVE: This study was performed to explore the clinical features, typing, distribution, and treatment of pulmonary sequestration (PS), with the aim of improving the awareness and treatment of this condition. METHODS: Clinical data regarding surgical procedures, outcomes, and prognosis of 208 pediatric patients with PS who were treated in our center from January 2005 to October 2017 were retrospectively analyzed. RESULTS: PS was confirmed by ultrasonography, enhanced computed tomography (CT), and/or magnetic resonance imaging (MRI) before surgery, and the surgeries were smoothly performed in all 208 patients (138 males, 70 females; age, 1 month to 14 years; mean age, 19.70 +/- 48.82 months). The operative time ranged from 10 to 230 min (mean, 70 +/- 48.75 min), and the intraoperative blood loss volume ranged from 1 to 200 ml (mean, 5 +/- 18 ml). PS was located in multiple sites of the thoracic cavity and was also found in some rare locations such as the neck and abdomen. The feeding arteries of the PS mainly arose from the thoracic aorta or abdominal aorta, and a few of them originated from other vessels in the systemic circulation. The venous drainage differed between intralobar and extralobar PS: in patients with intralobar PS, the venous drainage was mainly via the pulmonary veins, especially the lower pulmonary veins; in patients with extralobar PS, the venous drainage was via the azygos vein and hemiazygos vein or reached the right atrium via the vena cava. The infection rate in children with intralobar sequestration was 71.17% (79/111), and that in children with extralobar sequestration was 31.37% (16/51). CONCLUSION: PS has increasingly been detected by prenatal ultrasonography, and enhanced CT and MRI are the main techniques for diagnosing PS. Once confirmed, PS should be surgically resected. We choose an age of 6 to 12 months for surgical resection. Minimally invasive video-assisted thoracic surgery has many advantages in the treatment of PS and can be the treatment of choice for this condition. TYPE OF STUDY: Treatment Study. LEVEL OF EVIDENCE: Level III. PMID- 30291026 TI - Complications after proctocolectomy and ileal pouch-anal anastomosis in pediatric patients: A systematic review. AB - BACKGROUND/PURPOSE: Colectomy with ileal pouch-anal anastomosis (IPAA) is the standard of care for patients with familial adenomatous polyposis (FAP) and refractory ulcerative colitis (UC). The rates of postoperative complications are not well established in children. The objective of this systematic review is to establish benchmark data for morbidity after pediatric IPAA. METHODS: PubMed, Embase, and The Cochrane Library were searched for studies of colectomy with IPAA in patients <=21 years old. UC studies were limited to the anti-tumor necrosis factor-alpha agents era (1998-present). All postoperative complications were extracted. RESULTS: Thirteen studies met the inclusion criteria (763 patients). Compared to patients with FAP, UC patients had a higher prevalence of pouch loss (10.6% vs. 1.5%). Other major complications such as anastomotic leak, abscess, and fistula were uncommon (mean prevalence 4.9%, 4.2%, and 5.0%, respectively, for patients with UC; 8.7%, 4.2%, and 4.3% for FAP). The most frequent complication was pouchitis (36.4% of UC patients). CONCLUSIONS: Devastating complications from colectomy and IPAA are rare, but patients with UC have poorer outcomes than those with FAP. Much of the morbidity may therefore stem from patient or disease factors. Multicenter, prospective studies are needed to identify modifiable risks in patients with UC undergoing IPAA.

AB - B cells can present antigens to CD4+ T cells, but it is thought that dendritic cells (DCs) are the primary initiators of naive CD4+ T cell responses. Nanoparticles, including virus-like particles (VLPs), are attractive candidates as carriers for vaccines and drug delivery. Using RNA phage Qbeta-derived VLP (Qbeta-VLP) as a model antigen, we found that antigen-specific B cells were the dominant antigen-presenting cells that initiated naive CD4+ T cell activation. B cells were sufficient to induce T follicular helper cell development in the absence of DCs. Qbeta-specific B cells promoted CD4+ T cell proliferation and differentiation via cognate interactions and through Toll-like receptor signaling mediated cytokine production. Antigen-specific B cells were also involved in initiating CD4+ T cell responses during immunization with inactivated influenza virus. These findings have implications for the rational design of nanoparticles as vaccine candidates, particularly for therapeutic vaccines that aim to break immune tolerance.

AB - B cells thwart antigenic aggressions by releasing immunoglobulin M (IgM), IgG, IgA, and IgE, which deploy well-understood effector functions. In contrast, the role of secreted IgD remains mysterious. We found that some B cells generated IgD secreting plasma cells following early exposure to external soluble antigens such as food proteins. Secreted IgD targeted basophils by interacting with the CD44 binding protein galectin-9. When engaged by antigen, basophil-bound IgD increased basophil secretion of interleukin-4 (IL-4), IL-5, and IL-13, which facilitated the generation of T follicular helper type 2 cells expressing IL-4. These germinal center T cells enhanced IgG1 and IgE but not IgG2a and IgG2b responses to the antigen initially recognized by basophil-bound IgD. In addition, IgD ligation by antigen attenuated allergic basophil degranulation induced by IgE co ligation. Thus, IgD may link B cells with basophils to optimize humoral T helper type 2-mediated immunity against common environmental soluble antigens.

AB - BACKGROUND: Thrombectomy is the first choice for cardioembolism due to atrial fibrillation (AF), however, whether valvular AF and nonvalvular AF had different safety and functional outcomes has not been reported yet. We aimed to investigate the differences between patients with valvular AF and patients with nonvalvular AF on safety and functional outcomes in acute large artery occlusion undergoing thrombectomy. METHODS: Valvular AF refers to patients with mitral stenosis or artificial heart valves and valve repair. Rate of symptomatic intracerebral hemorrhage [sICH], modified Rankin Scale Score (mRS), and death at 90days were compared between valvular AF and nonvalvular AF groups. Univariate and multivariable logistic regression was performed to identify the predictors for unfavorable functional outcome (mRS 3-6). RESULTS: 18.8% (51/271) of AF were valvular AF. The valvular AF group had significantly higher proportion of mRS 0-2 (49% [25/51] versus 33.3% [73/219], P = .04) and less death (21.6% [11/51] versus 38.4% [84/219], P = .02) comparing with nonvalvular AF group. The rates of sICH between both groups were nonsignificantly different (21.5% [47/219] for nonvalvular AF versus 13.7% [7/51] for valvular AF, P = .46). Valvular AF was not an independent predictor for unfavorable functional outcome (odds ratio .67, 95% confidence interval: .24-1.84) with age, collateral flow, chronic heart failure, NIHSS at admission, recanalization status, glucose at admission, occlusion site, ASPECTS, and ICH as covariates. CONCLUSIONS: Valvular AF and nonvalvular AF have similar safety andfunctional outcomes in patients with acute anterior circulation large artery occlusion undergoing thrombectomy. PMID- 30291029 TI - Regulatory T Cells Promote Macrophage Efferocytosis during Inflammation Resolution. AB - Regulatory T (Treg) cell responses and apoptotic cell clearance (efferocytosis) represent critical arms of the inflammation resolution response. We sought to determine whether these processes might be linked through Treg-cell-mediated enhancement of efferocytosis. In zymosan-induced peritonitis and lipopolysaccharide-induced lung injury, Treg cells increased early in resolution, and Treg cell depletion decreased efferocytosis. In advanced atherosclerosis, where defective efferocytosis drives disease progression, Treg cell expansion improved efferocytosis. Mechanistic studies revealed the following sequence: (1) Treg cells secreted interleukin-13 (IL-13), which stimulated IL-10 production in macrophages; (2) autocrine-paracrine signaling by IL-10 induced Vav1 in macrophages; and (3) Vav1 activated Rac1 to promote apoptotic cell engulfment. In summary, Treg cells promote macrophage efferocytosis during inflammation resolution via a transcellular signaling pathway that enhances apoptotic cell internalization. These findings suggest an expanded role of Treg cells in inflammation resolution and provide a mechanistic basis for Treg-cell-enhancement strategies for non-resolving inflammatory diseases. PMID- 30291013 TI - Albiglutide and cardiovascular outcomes in patients with type 2 diabetes and cardiovascular disease (Harmony Outcomes): a double-blind, randomised placebo controlled trial. AB - BACKGROUND: Glucagon-like peptide 1 receptor agonists differ in chemical structure, duration of action, and in their effects on clinical outcomes. The cardiovascular effects of once-weekly albiglutide in type 2 diabetes are unknown. We aimed to determine the safety and efficacy of albiglutide in preventing cardiovascular death, myocardial infarction, or stroke. METHODS: We did a double blind, randomised, placebo-controlled trial in 610 sites across 28 countries. We randomly assigned patients aged 40 years and older with type 2 diabetes and cardiovascular disease (at a 1:1 ratio) to groups that either received a subcutaneous injection of albiglutide (30-50 mg, based on glycaemic response and tolerability) or of a matched volume of placebo once a week, in addition to their standard care. Investigators used an interactive voice or web response system to obtain treatment assignment, and patients and all study investigators were masked to their treatment allocation. We hypothesised that albiglutide would be non inferior to placebo for the primary outcome of the first occurrence of cardiovascular death, myocardial infarction, or stroke, which was assessed in the intention-to-treat population. If non-inferiority was confirmed by an upper limit of the 95% CI for a hazard ratio of less than 1.30, closed testing for superiority was prespecified. This study is registered with ClinicalTrials.gov, number NCT02465515. FINDINGS: Patients were screened between July 1, 2015, and Nov 24, 2016. 10 793 patients were screened and 9463 participants were enrolled and randomly assigned to groups: 4731 patients were assigned to receive albiglutide and 4732 patients to receive placebo. On Nov 8, 2017, it was determined that 611 primary endpoints and a median follow-up of at least 1.5 years had accrued, and participants returned for a final visit and discontinuation from study treatment; the last patient visit was on March 12, 2018. These 9463 patients, the intention-to-treat population, were evaluated for a median duration of 1.6 years and were assessed for the primary outcome. The primary composite outcome occurred in 338 (7%) of 4731 patients at an incidence rate of 4.6 events per 100 person-years in the albiglutide group and in 428 (9%) of 4732 patients at an incidence rate of 5.9 events per 100 person-years in the placebo group (hazard ratio 0.78, 95% CI 0.68-0.90), which indicated that albiglutide was superior to placebo (p<0.0001 for non-inferiority; p=0.0006 for superiority). The incidence of acute pancreatitis (ten patients in the albiglutide group and seven patients in the placebo group), pancreatic cancer (six patients in the albiglutide group and five patients in the placebo group), medullary thyroid carcinoma (zero patients in both groups), and other serious adverse events did not differ between the two groups. There were three (<1%) deaths in the placebo group that were assessed by investigators, who were masked to study drug assignment, to be treatment-related and two (<1%) deaths in the albiglutide group. INTERPRETATION: In patients with type 2 diabetes and cardiovascular disease, albiglutide was superior to placebo with respect to major adverse cardiovascular events. Evidence-based glucagon-like peptide 1 receptor agonists should therefore be considered as part of a comprehensive strategy to reduce the risk of cardiovascular events in patients with type 2 diabetes.

AB - BACKGROUND: QT dispersion, maximal interlead difference in QT interval on 12-lead electrocardiogram (ECG), measures cardiac repolarization abnormalities. Data are conflicting whether QT dispersion predicts adverse outcome in acute ischemic stroke (AIS) patients. Our objective is to determine if QT dispersion predicts: (1) short-term clinical outcome in AIS, and (2) stroke location (insular versus noninsular cortex). METHODS: Admission ECGs from 412 consecutive patients with acute stroke symptoms from 2 university-based stroke centers were reviewed. QT dispersion was measured. A neuroradiologist reviewed brain imaging for insular cortex involvement. Favorable clinical outcomes at discharge were modified Rankin Scale (mRS) score of 0-1, discharge National Institutes of Health Stroke Scale (NIHSS) score less than 2, and discharge to home. Multiple logistic regressions were performed for each outcome measure and to determine the association between insular infarct and QT dispersion. RESULTS: Of 145 subjects in the final analysis, median age was 65years (interquartile range [IQR] 56-75), male patients were 38%, black patients were 68%, median QT dispersion was 78 milliseconds (IQR 59-98), and median admission NIHSS score was 4 (IQR 2-6). QT dispersion did not predict short-term clinical outcome for mRS score (odds ratio [OR] = 1.001, 95% confidence interval [CI] .99-1.01, P = .85), NIHSS at discharge (OR = .994, 95% CI .98-1.01, P = .30), or discharge disposition (OR = 1.001, 95% CI .99-1.01, P = .81). Insular cortex involvement did not correlate with QT dispersion magnitude (OR = 1.009, 95% CI .99-1.02, P = .45). CONCLUSIONS: We could not demonstrate that QT dispersion is useful in predicting short-term clinical outcome at discharge in AIS. Further, the magnitude of QT dispersion did not predict insular cortical stroke location. PMID- 30291032 TI - Ten-year epidemiological study in an orthopaedic and trauma surgery centre: Are there risks involved in increasing scheduled arthroplasty volume without increasing resources? AB - BACKGROUND: Current trends in patient management include decreasing hospital stay lengths and reductions in available material and human resources. A shortening of hospital stays in university hospitals has been documented over the last decade. However, to our knowledge, no study has assessed possible relationships linking shorter stays to staffing levels or complication rates. The objectives of this study were: 1) to assess changes in case volume in a university orthopaedics and trauma surgery department between 2006 and 2016, 2) and to look for correlations linking these changes to staffing levels and the rates of significant complications, including the number of hip dislocations after total hip arthroplasty (THA) and the number of infections and complications resulting in malpractice litigation after hip, knee, or shoulder arthroplasty. HYPOTHESIS: The case volume increased during the study period, whereas resources remained unchanged or decreased. MATERIAL AND METHODS: A retrospective study was performed using the electronic database of an orthopaedics and trauma surgery department. Data collected between 2006 and 2016 were analysed. Mean hospital stay length, patient age, and surgical volume were recorded, and changes over time in case volume for trauma surgery and scheduled arthroplasties were evaluated. Changes in staffing levels and rates of complications (dislocation after THA and infections and complications resulting in malpractice litigation) between 2006 and 2016 were assessed. Only arthroplasty procedures performed in the department were considered for the study of complications and litigation. RESULTS: Between 2006 and 2016, mean hospital stay decreased from 8.7+/-10.8 days (range, 0-141 days) in to 7.0+/-9.4 days (range, 0-150 days). Mean patient age increased from 54.4+/ 21.2 years (range, 11.7-100.9 years) in 2006 to 59.3+/-20.9 years (range, 13.2 103.1 years) in 2016. The total number of procedures rose from 2158 in 2006 to 3100 in 2016 (+43.6%). The number of THAs increased by 16.2% and the number of total knee arthroplasties by 96.7%. The number of operations for trauma increased from 725 in 2006 to 1135 in 2016 (+56.0%). During the study period, the number of hospital beds declined from 70 to 55. No increase was seen in the frequencies of dislocation after THA (3/284 [1.4%] in 2006 and 4/330 [1.2%] in 2016) or prosthetic joint infection (5/439 [1.1%] in 2006 and 6/657 [0.9%] in 2016). In contrast, malpractice suits filed by patients after arthroplasty increased from 1/439 (0.2%) in 2006 to 8/657 (1.2%) in 2016. CONCLUSION: Over the last decade, trauma and arthroplasty surgical volumes increased substantially, whereas staffing levels remained unchanged and number of beds diminished. The frequency of significant complications such as dislocation after THA did not increase. In contrast, a marked rise was seen in malpractice litigation. However, the increased volume with unchanged resources found in this study should be interpreted in the light of the marked increase in patient dependency and of our role as a referral centre managing patients with complications after surgery performed at other institutions.

AB - BACKGROUND: Use of an age-adjusted D-dimer for the evaluation of acute pulmonary embolus (PE) has been prospectively validated in the literature and has become a practice recommendation from major medical societies. Most research on this subject involves the most common D-dimer assays reporting in Fibrinogen Equivalent Units (FEU) with a non-age-adjusted manufacturer-recommended cutoff of 500 ng/ml FEU. Limited research to date has evaluated age-adjustment in assays that report in D-Dimer Units (D-DU), which use a manufacturer-recommended cutoff of 230 ng/ml D-DU. Despite scant evidence, an age-adjusted formula using D-DU has been recently endorsed by the American College of Emergency Physicians (ACEP). This formula seems arbitrary in its derivation and unnecessarily deviates from existing thresholds, thus prompting the creation of our novel-age adjustment formula. The goal of this study was to retrospectively evaluate the test characteristics of our novel age-adjusted D-dimer formula using the D-DU assay in comparison to existing traditional and age-adjusted D-dimer thresholds for the evaluation of acute PE in the ED. METHODS: This was a retrospective chart review at an academic quaternary health system with three EDs and 195,000 combined annual ED visits. Only patients with D-dimer testing and CT PE protocol (CTPE) imaging were included. Admission and discharge diagnosis codes were used to identify acute PE. Outcome measures were sensitivity, specificity, negative predictive value (NPV) and positive predictive value (PPV) of an unadjusted traditional threshold (230) compared with both novel and ACEP-endorsed age adjusted thresholds, (Age * 5) - 20 and Age * 5 if >50, respectively. Estimates with their exact 95% threshold were performed. RESULTS: 4846 adult patients were evaluated from January 2012 to July 2017. Group characteristics include a mean age of 52 and a frequency of acute PE diagnosis by CTPE of 8.25%. Traditional D dimer cutoff demonstrated a sensitivity of 99.8% (95% CI 98.6-100), specificity of 16.7% (95% CI 15.6-17.8) and NPV of 99.9% (95% CI 99.3-100). Our novel age adjusted D-dimer thresholds had a sensitivity of 97.0% (95% CI 94.8-98.4), specificity of 27.9% (95% CI 26.6-29.2) and NPV of 99.0% (95% CI 98.3-99.5) with the ACEP-endorsed formula demonstrating similar test characteristics. CONCLUSION: Use of an age-adjusted D-dimer on appropriately selected patients being evaluated for acute PE in the ED with a D-DU assay increases specificity while maintaining a high sensitivity and NPV. Both our novel formula and the ACEP-endorsed age adjusted formula performed well, with our novel formula showing a trend towards improved testing characteristics. PMID- 30291036 TI - Intestinal pseudo-obstruction as the initial manifestation of systemic lupus erythematosus. AB - Small bowel obstruction is common in emergency departments. However, the exact cause of intestinal pseudo-obstruction (IPO) is often misdiagnosed. IPO is considered a severe manifestation of systemic lupus erythematosus (SLE). However, IPO is rare as the initial manifestation of SLE. This paper reports a female patient who presented with IPO as the initial manifestation and was ultimately diagnosed with SLE. The 31-year-old female was definitively diagnosed with SLE after IPO symptoms for 1 month. She then presented multiple organ dysfunction syndrome (MODS) leading to a poor prognosis. Patients with unexplained SBO symptoms should be aware of systemic diseases. Early diagnosis and prompt medical treatment are crucial to avoid unnecessary surgery and obtain satisfactory outcomes. PMID- 30291037 TI - The SDQ dysregulation profile is associated with self-injurious thoughts and behaviors in adolescents evaluated at a clinical setting. AB - INTRODUCTION: Suicidal ideation, suicidal behavior, and non-suicidal self-injury behavior are serious public health problems among adolescents. A significant proportion of adolescents evaluated in clinical settings meet criteria for the dysregulation profile (DP). DP is characterized by restlessness, irritability, "affective storms", mood instability, and aggression in a disproportionate grade to the situation. This DP might be related to increased risk of self-injurious thoughts and behaviors. METHODS: Two hundred and thirty-nine adolescents from the Child and Adolescent Outpatient Psychiatric Services of the Jimenez Diaz Foundation, Madrid, were assessed with the Strengths and Difficulties Questionnaire-Dysregulation Profile, the Self-Injurious Thoughts and Behaviors Interview and socio-demographic questionnaires. RESULTS: Logistic regression showed that DP adolescents were at increased risk for suicide plans, gestures, and suicide attempts. They also tended to present more self-injurious behaviors than adolescents without DP. CONCLUSIONS: Our results point to the role of self regulatory problems in the presence of suicide plans, suicide gestures, suicide attempts, and in non-suicidal self-injury behavior. Longitudinal studies are needed to confirm the relationship between the Strengths and Difficulties Questionnaire-Dysregulation Profile and self-injurious thoughts and behaviors.

PMID- 30291039 TI - Modelling cervical cancer elimination. PMID- 30291040 TI - The projected timeframe until cervical cancer elimination in Australia: a modelling study. AB - BACKGROUND: In 2007, Australia was one of the first countries to introduce a national human papillomavirus (HPV) vaccination programme, and it has since achieved high vaccination coverage across both sexes. In December, 2017, organised cervical screening in Australia transitioned from cytology-based screening every 2 years for women aged from 18-20 years to 69 years, to primary HPV testing every 5 years for women aged 25-69 years and exit testing for women aged 70-74 years. We aimed to identify the earliest years in which the annual age standardised incidence of cervical cancer in Australia (which is currently seven cases per 100 000 women) could decrease below two annual thresholds that could be considered to be potential elimination thresholds: a rare cancer threshold (six new cases per 100 000 women) or a lower threshold (four new cases per 100 000 women), since Australia is likely to be one of the first countries to reach these benchmarks. METHODS: In this modelling study, we used Policy1-Cervix-an extensively validated dynamic model of HPV vaccination, natural history, and cervical screening-to estimate the age-standardised incidence of cervical cancer in Australia from 2015 to 2100. We incorporated age-specific coverage of the Australian National HPV Vaccination Program in girls, including the catch-up programme, and the inclusion of boys into the vaccine programme from 2013, and a change from the quadrivalent to the nonavalent vaccine from 2018. We also modelled the effects of the transition to primary HPV screening. We considered two scenarios for future screening recommendations regarding the cohorts who will be and who have been offered the nonavalent vaccine: either that HPV screening every 5 years continues, or that no screening would be offered to these women. FINDINGS: We estimate that, in Australia, the age-standardised annual incidence of cervical cancer will decrease to fewer than six new cases per 100 000 women by 2020 (range 2018-22), and to fewer than four new cases per 100 000 women by 2028 (2021-35). The precise year of attaining these rates is dependent on the population used for age-standardisation, HPV screening behaviour and test characteristics, the incremental effects of vaccination of men on herd immunity in women, and assumptions about the future frequency of benign hysterectomies. By 2066 (2054-77), the annual incidence of cervical cancer will decrease and remain at fewer than one case per 100 000 women if screening for HPV every 5 years continues for cohorts who have been offered the nonavalent vaccine, or fewer than three cases per 100 000 women if these cohorts are not screened. Cervical cancer mortality is estimated to decrease to less than an age-standardised annual rate of one death per 100 000 women by 2034 (2025-47), even if future screening is only offered to older cohorts that were not offered the nonavalent vaccine. INTERPRETATION: If high-coverage vaccination and screening is maintained, at an elimination threshold of four new cases per 100 000 women annually, cervical cancer could be considered to be eliminated as a public health problem in Australia within the next 20 years. However, screening and vaccination initiatives would need to be maintained thereafter to maintain very low cervical cancer incidence and mortality rates.

AB - This study investigated the in vitro susceptibility of ceftobiprole and its potential synergistic activity in combination with other antimicrobials against 46 selected Gram-positive pathogens displaying resistance or decrease susceptibility to several drugs. The gradient-cross method was used to assess synergism between ceftobiprole and daptomycin, levofloxacin, linezolid, rifampicin and piperacillin/tazobactam. Time-kill curves were performed for seven representative isolates. Ceftobiprole MICs ranged from 0.25-6 mg/L for staphylococci; 4->=32 mg/L for Enterococcus faecalis, and 0.38->=32 mg/L for E. faecium. Ceftobiprole plus daptomycin was synergistic against all isolates. Ceftobiprole plus linezolid was synergistic against 4 isolates belonging to different species. Ceftobiprole plus levofloxacin was synergistic only against enterococci. In conclusion, ceftobiprole exhibited a potent in vitro antibacterial activity and exhibited synergy with daptomycin against all Gram positive isolates, despite their antibiotic resistance phenotypes. The use of ceftobiprole in combination may provide a promising alternative therapy for the treatment of resistant Gram-positive infections.

PMID- 30291044 TI - Replication protein A as a modulator of the poly(ADP-ribose)polymerase 1 activity. AB - Replication protein A contributes to all major pathways of DNA metabolism and is a target for post-translation modifications, including poly(ADP-ribosyl)ation catalyzed by PARP1. Here we demonstrate that the efficiency of RPA poly(ADP ribosyl)ation strongly depends on the structure of DNA used for PARP1 activation and on the polarity of RPA binding. Moreover, RPA influences PARP1 activity, and this effect also depends on DNA structure: RPA inhibits PAR synthesis catalyzed by PARP1 in the presence of ssDNA and stimulates it in the presence of a DNA duplex, in particular that containing a nick or a gap. Using fluorescently labeled proteins, we showed their direct interaction and characterized it quantitatively. RPA can accelerate the replacement of poly(ADP-ribosyl)ated PARP1 molecules bound to DNA by the unmodified ones. Thus, our data allow us to suggest that the balance between the affinities of PARP1 and RPA for DNA and the interaction of these proteins with each other are the cornerstone of the modulating effect of RPA on PARP1 activity. This effect might contribute to the regulation of PARP1 activity in various DNA processing mechanisms including DNA replication and repair pathways, where both PARP1 and RPA participate. PMID- 30291045 TI - The rising incidence and impact of non-medically indicated pre-labour cesarean section in Latin America. AB - In the poorest populations of the world the difficulties of performing a surgical procedure lead to extremely low cesarean section rates associated with very high perinatal mortality. Meanwhile the proportion of births by cesarean section has been increasing for several decades in many areas of the world, reaching alarmingly high rates especially in Latin America. This review aims to describe this secular trend. The causes of the increase in cesarean deliveries are analyzed with a multidimensional approach, trying to recognize the reasons behind the choice of the route of delivery. We are facing a shift in the guiding paradigm, leaving the classical biomedical one. Advantages and disadvantages of non-medically indicated cesarean section are being sought, comparing it with the results of vaginal delivery, with special emphasis on the short- and long-term morbidity of the newborn. Several variables involved in this controversial topic are considered, with the objective of stimulating critical thoughts about the medical, bioethical and social aspects of the increasing trend in the cesarean section rate.

AB - Full-thickness skin grafts (FTSGs) and flaps from the upper eyelid or cheek can be used for reconstruction of lower eyelid defects, including the anterior lamella. However, the upper eyelid has a limited and insufficient amount of skin, whereas cheek flaps have a restricted arch of rotation. Here we report the procedure and outcomes of a perforator/subcutaneous pedicled propeller flap for reconstruction of lower eyelid defects including the anterior lamella. A retrospective study of 12 patients who underwent treatment for eyelid anterior lamella defects with perforator/subcutaneous pedicled propeller flaps was conducted between March 2015 and June 2017. The propeller flap was planned to rotate around the perforator (as the pivot point), which was detected with a hand held Doppler in the vicinity of the defect. The flaps were perforator pedicled for 10 patients and subcutaneous pedicled for the other two patients. The flap was rotated around the pedicle and placed on each patient's defect without tension. No vascular compromise occurred with any of the flaps. The most important complications were post-operative oedema and ecchymosis. Inferior eyelid defects including the anterior lamella could be reconstructed by using propeller flaps from the adjacent tissue. The main advantages of this flap included easy access to the defect, no impairment in eyelid function and very good aesthetic results.

AB - BACKGROUND: This study aimed to investigate the versatility of septocutaneous thoracodorsal artery perforator (TDAP-sc) flaps in various areas in the body and the running pattern of septocutaneous perforators. METHODS: This retrospective cohort study included 20 consecutive patients who underwent reconstruction of an oncological defect with a TDAP-sc flap from May 2014 to January 2018. Fifteen flaps were free, and the remaining five were pedicled. Surgical details and postoperative complications were investigated. RESULTS: The flap size ranged from 13 * 6.5 to 22 * 15 cm. The defect location was the upper extremity in eight patients, the head and neck in six, the lower extremity in four, and the trunk in two. The septocutaneous perforator arose from the thoracodorsal vessels proximal to the serratus anterior branch in 10 (50.0%) patients, from the thoracodorsal vessels distal to the serratus anterior branch in six (30.0%), and from the serratus anterior branch in four (20.0%). All flaps completely survived, except the one with partial necrosis. The scapula was simultaneously harvested based on the angular branch in three patients who underwent mandibular reconstruction. CONCLUSIONS: The TDAP-sc flap can be a versatile option for various types of reconstruction if a dominant septocutaneous perforator is present. Prevalence of a dominant TDAP-sc is estimated at approximately 50%. However, this flap can be harvested without tedious intramuscular dissection, and the two-team approach is possible during tumor resection. The presence of a dominant septocutaneous perforator can expand indication of the TDAP flap.

AB - BACKGROUND: Breast reduction is one of the most common procedures performed by plastic surgeons. Despite good outcomes and high patient satisfaction, there are little national data on the predictors that lead to complications in this patient population. We accessed a national outcomes database to examine these factors. METHODS: This is a retrospective study examining the National Surgical Quality Improvement Program database from 2006 to 2015. Patients who underwent primary breast reduction were identified. Patients who underwent any cancer-related procedures were excluded. We identified patient-related and procedure-related factors for analysis. Univariate and multivariate logistic regression analyses were used to identify independent predictors of complications. RESULTS: In total, 16,812 individual cases were identified. The overall complication rate for the cohort was 6.2%, and the major complication rate was 3.0%. Diabetes, bleeding disorder, hypertension, obesity, smoking, steroid use, and prolonged operative time were associated with increased risk of complications (p < 0.05). Concurrent body contouring was a predictor of increased major complications; however, liposuction was not. CONCLUSIONS: Common surgical risk factors are associated with complications in breast reduction surgery. Although liposuction is not an independent risk factor, concurrent body contouring is associated with increased complications. Surgeons should be aware of these associations when discussing breast reduction with patients. PMID- 30291051 TI - Smartphone App Use for Diabetes Management: Evaluating Patient Perspectives. AB - BACKGROUND: Finding novel ways to engage patients in chronic disease management has led to increased interest in the potential of mobile health technologies for the management of diabetes. There is currently a wealth of smartphone apps for diabetes management that are available for free download or purchase. However, the usability and desirability of these apps has not been extensively studied. These are important considerations, as these apps must be accepted by the patient population at a practical level if they are to be utilized. OBJECTIVE: The purpose of this study was to gain insight into patient experiences related to the use of smartphone apps for the management of type 1 diabetes. METHODS: Adults with type 1 diabetes who had previously (or currently) used apps to manage their diabetes were eligible to participate. Participants (n=12) completed a questionnaire in which they were required to list the names of preferred apps and indicate which app functions they had used. Participants were given the opportunity to comment on app functions that they perceived to be missing from the current technology. Participants were also asked whether they had previously paid for an app and whether they would be willing to do so. RESULTS: MyFitnessPal and iBGStar were the apps most commonly listed as the best available on the market. Blood glucose tracking, carbohydrate counting, and activity tracking were the most commonly used features. Ten participants fulfilled all eligibility criteria, and indicated that they had not encountered any one app that included all of the functions that they had used. The ability to synchronize an app with a glucometer or insulin pump was the most common function that participants stated was missing from current app technology. One participant had previously paid for a diabetes-related app and the other 9 participants indicated that they would be willing to pay. CONCLUSIONS: Despite dissatisfaction with the currently available apps, there is interest in using these tools for diabetes management. Adapting existing technology to better meet the needs of this patient population may allow these apps to become more widely utilized. PMID- 30291052 TI - Mixed-Methods Research in Diabetes Management via Mobile Health Technologies: A Scoping Review. AB - BACKGROUND: Considering the increasing incidence and prevalence of diabetes worldwide and the high level of patient involvement it requires, diabetes self management is a serious issue. The use of mobile health (mHealth) in diabetes self-management has increased, but so far research has not provided sufficient information about the uses and effectiveness of mHealth-based interventions. Alternative study designs and more rigorous methodologies are needed. Mixed methods designs may be particularly useful because both diabetes self-management and mHealth studies require integrating theoretical and methodological approaches. OBJECTIVE: This scoping review aimed to examine the extent of the use of mixed-methods research in mHealth-based diabetes management studies. The methodological approaches used to conduct mixed-methods studies were analyzed, and implications for future research are provided. METHODS: Guided by Arksey and O'Malley's framework, this scoping review implemented a comprehensive search strategy including reviewing electronic databases, key journal searches, Web based research and knowledge centers, websites, and handsearching reference lists of the studies. The studies focusing on mHealth technologies and diabetes management were included in the review if they were primary research papers published in academic journals and reported using a combination of qualitative and quantitative methods. The key data extracted from the reviewed studies include purpose of mixing, design type, stage of integration, methods of legitimation, and data collection techniques. RESULTS: The final sample (N=14) included studies focused on the feasibility and usability of mHealth diabetes apps (n=7), behavioral measures related to the mHealth apps (n=6), and challenges of intervention delivery in the mHealth context (n=1). Reviewed studies used advanced forms of mixed-methods designs where integration occurred at multiple points and data were collected using multiple techniques. However, the majority of studies did not identify a specific mixed-methods design or use accepted terminology; nor did they justify using this approach. CONCLUSIONS: This review provided important insights into the use of mixed methods in studies focused on diabetes management via mHealth technologies. The prominent role of qualitative methods and tailored measures in diabetes self-management studies was confirmed, and the importance of using multiple techniques and approaches in this field was emphasized. This review suggests defining specific mixed-methods questions, using specific legitimation methods, and developing research designs that overcome sampling and other methodological problems in future studies. PMID- 30291053 TI - Use of Social Media in the Diabetes Community: An Exploratory Analysis of Diabetes-Related Tweets. AB - BACKGROUND: Use of social media is becoming ubiquitous, and disease-related communities are forming online, including communities of interest around diabetes. OBJECTIVE: Our objective was to examine diabetes-related participation on Twitter by describing the frequency and timing of diabetes-related tweets, the geography of tweets, and the types of participants over a 2-year sample of 10% of all tweets. METHODS: We identified tweets with diabetes-related search terms and hashtags in a dataset of 29.6 billion tweets for the years 2013 and 2014 and extracted the text, time, location, retweet, and user information. We assessed the frequencies of tweets used across different search terms and hashtags by month and day of week and, for tweets that provided location information, by country. We also performed these analyses for a subset of tweets that used the hashtag #dsma, a social media advocacy community focused on diabetes. Random samples of user profiles in the 2 groups were also drawn and reviewed to understand the types of stakeholders participating online. RESULTS: We found 1,368,575 diabetes-related tweets based on diabetes-related terms and hashtags. There was a seasonality to tweets; a higher proportion occurred during the month of November, which is when World Diabetes Day occurs. The subset of tweets with the #dsma were most frequent on Thursdays (coordinated universal time), which is consistent with the timing of a weekly chat organized by this online community. Approximately 2% of tweets carried geolocation information and were most prominent in the United States (on the east and west coasts), followed by Indonesia and the United Kingdom. For the user profiles randomly selected among overall tweets, we could not identify a relationship to diabetes for the majority of users; for the profiles using the #dsma hashtag, we found that patients with type 1 diabetes and their caregivers represented the largest proportion of individuals. CONCLUSIONS: Twitter is increasingly becoming a space for online conversations about diabetes. Further qualitative and quantitative content analysis is needed to understand the nature and purpose of these conversations. PMID- 30291054 TI - Data Mining of a Remote Behavioral Tracking System for Type 2 Diabetes Patients: A Prospective Cohort Study. AB - BACKGROUND: Complications from type 2 diabetes mellitus can be prevented when patients perform health behaviors such as vigorous exercise and glucose-regulated diet. The use of smartphones for tracking such behaviors has demonstrated success in type 2 diabetes management while generating repositories of analyzable digital data, which, when better understood, may help improve care. Data mining methods were used in this study to better understand self-monitoring patterns using smartphone tracking software. OBJECTIVE: Associations were evaluated between the smartphone monitoring of health behaviors and HbA1c reductions in a patient subsample with type 2 diabetes who demonstrated clinically significant benefits after participation in a randomized controlled trial. METHODS: A priori association-rule algorithms, implemented in the C language, were applied to app discretized use data involving three primary health behavior trackers (exercise, diet, and glucose monitoring) from 29 participants who achieved clinically significant HbA1c reductions. Use was evaluated in relation to improved HbA1c outcomes. RESULTS: Analyses indicated that nearly a third (9/29, 31%) of participants used a single tracker, half (14/29, 48%) used two primary trackers, and the remainder (6/29, 21%) of the participants used three primary trackers. Decreases in HbA1c were observed across all groups (0.97-1.95%), but clinically significant reductions were more likely with use of one or two trackers rather than use of three trackers (OR 0.18, P=.04). CONCLUSIONS: Data mining techniques can reveal relevant coherent behavior patterns useful in guiding future intervention structure. It appears that focusing on using one or two trackers, in a symbolic function, was more effective (in this sample) than regular use of all three trackers. PMID- 30291055 TI - Widely Viewed English Language YouTube Videos Relating to Diabetic Retinopathy: A Cross-Sectional Study. AB - BACKGROUND: An emergent source of information on health issues is the Internet. One such platform with 1 billion users is YouTube, the global video-sharing service. OBJECTIVE: The purpose of this study was to describe the content and characteristics of the most widely viewed YouTube videos related to diabetic retinopathy. METHODS: Videos were sorted according to number of views using the key words "diabetic retinopathy." For each video, general descriptive information was collected. This information included date and source of upload (news, professional, or consumer), length, and total number of views as of July 18, 2016. Content categories were largely informed by a National Eye Institute fact sheet. Each video was viewed to determine which, if any, of the given content categories were present. RESULTS: Of the 98 most widely viewed videos related to diabetic retinopathy, 42 were generated by consumers, 40 were generated by professionals, and 16 were generated from news-based sources. The largest number of views were generated from professionals (624,770/994,494, 63.82%). Compared with professional videos, consumer videos were viewed less frequently (W=622, P=.04). The main purpose of the majority of videos was to provide information (59/98, 60%), and most of the videos showed or mentioned retinopathy in general (75/98, 77%). Smaller numbers offered information about specific types of retinopathy, namely proliferative (26/98, 27%) and nonproliferative (17/98, 17%). Compared with consumer-generated videos, professional videos were 5.57 times more likely to mention that diabetic retinopathy can go unnoticed (95% CI 1.59-26.15). More than 80% (80/98) of the most widely viewed videos did not address the asymptomatic nature of the disease, only about one-third (33/98) mentioned prevention, and only 58 of the 98 videos (59%) mentioned screening. CONCLUSION: Future research is needed to identify aspects of YouTube videos that attract viewer attention and best practices for using this medium to increase diabetic retinopathy screening among people with diabetes. PMID- 30291056 TI - Evaluating the Accuracy of Google Translate for Diabetes Education Material. AB - BACKGROUND: Approximately 21% of the US population speaks a language other than English at home; many of these individuals cannot effectively communicate in English. Hispanic and Chinese Americans, in particular, are the two largest minority groups having low health literacy in the United States. Fortunately, machine-generated translations represent a novel tool that non-English speakers can use to receive and relay health education information when human interpreters are not available. OBJECTIVE: The purpose of this study was to evaluate the accuracy of the Google Translate website when translating health information from English to Spanish and English to Chinese. METHODS: The pamphlet, "You are the heart of your family...take care of it," is a health education sheet for diabetes patients that outlines six tips for behavior change. Two professional translators translated the original English sentences into Spanish and Chinese. We recruited 6 certified translators (3 Spanish and 3 Chinese) to conduct blinded evaluations of the following versions: (1) sentences translated by Google Translate, and (2) sentences translated by a professional human translator. Evaluators rated the sentences on four scales: fluency, adequacy, meaning, and severity. We performed descriptive analysis to examine differences between these two versions. RESULTS: Cronbach's alpha values exhibited high degrees of agreement on the rating outcome of both evaluator groups: .919 for the Spanish evaluators and .972 for the Chinese evaluators. The readability of the sentences in this study ranged from 2.8 to 9.0 (mean 5.4, SD 2.7). The correlation coefficients between the grade level and translation accuracy for all sentences translated by Google were negative (eg, rMeaning=-.660), which indicates that Google provided accurate translation for simple sentences. However, the likelihood of incorrect translation increased when the original English sentences required higher grade levels to comprehend. The Chinese human translator provided more accurate translation compared to Google. The Spanish human translator, on the other hand, did not provide a significantly better translation compared to Google. CONCLUSION: Google produced a more accurate translation from English to Spanish than English to Chinese. Some sentences translated by Google from English to Chinese exhibit the potential to result in delayed patient care. We recommend continuous training and credential practice standards for professional medical translators to enhance patient safety as well as providing health education information in multiple languages. PMID- 30291057 TI - The Use of Mobile Health to Deliver Self-Management Support to Young People With Type 1 Diabetes: A Cross-Sectional Survey. AB - BACKGROUND: Young people living with type 1 diabetes face not only the challenges typical of adolescence, but also the challenges of daily management of their health and evolving understanding of the impact of their diagnosis on their future. Adolescence is a critical time for diabetes self-management, with a typical decline in glycemic control increasing risk for microvascular diabetes complications. To improve glycemic control, there is a need for evidence-based self-management support interventions that address the issues pertinent to this population, utilizing platforms that engage them. Increasingly, mobile health (mHealth) interventions are being developed and evaluated for this purpose with some evidence supporting improved glycemic control. A necessary step to enhance effectiveness of such approaches is to understand young people's preferences for this mode of delivery. OBJECTIVE: A cross-sectional survey was conducted to investigate the current and perceived roles of mHealth in supporting young people to manage their diabetes. METHODS: Young adults (16-24 years) with type 1 diabetes in Auckland, New Zealand, were invited to take part in a survey via letter from their diabetes specialist. RESULTS: A total of 115 young adults completed the survey (mean age 19.5 years; male 52/115, 45%; European 89/115, 77%), with all reporting they owned a mobile phone and 96% (110/115) of those were smartphones. However, smartphone apps for diabetes management had been used by only 33% (38/115) of respondents. The most commonly reported reason for not using apps was a lack of awareness that they existed. Although the majority felt they managed their diabetes well, 63% (72/115) reported wanting to learn more about diabetes and how to manage it. A total of 64% (74/115) respondents reported that they would be interested in receiving diabetes self-management support via text message (short message service, SMS). CONCLUSIONS: Current engagement with mHealth in this population appears low, although the findings from this study provide support for the use of mHealth in this group because of the ubiquity and convenience of mobile devices. mHealth has potential to provide information and support to this population, utilizing mediums commonplace for this group and with greater reach than traditional methods. PMID- 30291058 TI - Telemonitoring and Health Counseling for Self-Management Support of Patients With Type 2 Diabetes: A Randomized Controlled Trial. AB - BACKGROUND: The prevalence of diabetes is increasing among adults globally, and there is a need for new models of health care delivery. Research has shown that self-management approaches encourage persons with chronic conditions to take a primary role in managing their daily care. OBJECTIVE: The objective of this study was to investigate whether the introduction of a health technology-supported self management program involving telemonitoring and health counseling had beneficial effects on glycated hemoglobin (HbA1c), other clinical variables (height, weight, body mass index, blood pressure, blood lipid profile), and health-related quality of life (HRQoL), as measured using the Short Form Health Survey (SF-36) version 2 in patients with type 2 diabetes. METHODS: This was a pragmatic randomized controlled trial of patients with type 2 diabetes. Both the control and intervention groups received usual care. The intervention group also participated in additional health promotion activities with the use of the Prescribed Healthcare Web application for self-monitoring of blood glucose and blood pressure. About every second month or when needed, the general practitioner or the diabetes nurse reviewed the results and the health care activity plan. RESULTS: A total of 166 patients with type 2 diabetes were randomly assigned to the intervention (n=87) or control (n=79) groups. From the baseline to follow-up, 36 patients in the intervention group and 5 patients in the control group were lost to follow-up, and 2 patients died. Additionally, HbA1c was not available at baseline in one patient in the intervention group. A total of 122 patients were included in the final analysis after 19 months. There were no significant differences between the groups in the primary outcome HbA1c level (P=.33), and in the secondary outcome HRQoL as measured using SF-36. A total of 80% (67/87) of the patients in the intervention group at the baseline, and 98% (47/50) of the responders after 19-month intervention were familiar with using a personal computer (P=.001). After 19 months, nonresponders (ie, data from baseline) reported significantly poorer mental health in social functioning and role emotional subscales on the SF-36 (P=.03, and P=.01, respectively). CONCLUSIONS: The primary outcome HbA1c level and the secondary outcome HRQoL did not differ between groups after the 19-month follow-up. Those lost to follow-up reported significantly poorer mental health than did the responders in the intervention group. TRIAL REGISTRATION: Clinicaltrials.gov NCT01478672; https://clinicaltrials.gov/ct2/show/NCT01478672 (Archived by WebCite at http://www.webcitation.org/6r4eILeyu). PMID- 30291059 TI - One Drop | Mobile: An Evaluation of Hemoglobin A1c Improvement Linked to App Engagement. AB - BACKGROUND: Three recent reviews evaluated 19 studies testing the hemoglobin A1c (HbA1c) benefit of 16 diabetes apps, including 5 publicly available apps. Most studies relied on small samples and did not link app engagement with outcomes. OBJECTIVE: This study assessed both HbA1c change in a large sample of people using the One Drop | Mobile app and associations between app engagement and changes in HbA1c. METHODS: The One Drop | Mobile app for iOS and Android is designed to manually and passively (via Apple HealthKit, Google Fit, and the One Drop | Chrome blood glucose meter) store, track, and share data. Users can schedule medication reminders, view statistics, set goals, track health outcomes, and get data-driven insights. In June 2017, we queried data on people with diabetes using the app who had entered at least 2 HbA1c values in the app >60 and <=365 days apart. Multiple imputation corrected for missing data. Unadjusted and adjusted mixed effects repeated measures models tested mean HbA1c change by time, diabetes type, and their interaction. Multiple regression models assessed relationships between using the app to track food, activity, blood glucose, and medications and HbA1c change. RESULTS: The sample (N=1288) included people with type 1 diabetes (T1D) (n=367) or type 2 diabetes (T2D) (n=921) who were 35% female, diagnosed with diabetes for a mean 9.4 (SD 9.9) years, and tracked an average 1646.1 (SD 3621.9) self-care activities in One Drop | Mobile between their first (mean 8.14% [SD 2.06%]) and second HbA1c entry (mean 6.98% [SD 1.1%]). HbA1c values were significantly associated with user-entered average blood glucose 90 days before the second HbA1c entry (rho=.73 to .75, P<.001). HbA1c decreased by an absolute 1.07% (unadjusted and adjusted F=292.03, P<.001) from first to second HbA1c entry. There was a significant interaction between diabetes type and HbA1c. Both groups significantly improved, but users with T2D had a greater HbA1c decrease over time than users with T1D (F=10.54, P<.001). For users with T2D (n=921), HbA1c decreased by an absolute 1.27% (F=364.50, P<.001) from first to second HbA1c entry. Finally, using One Drop | Mobile to record food was associated with greater HbA1c reductions even after adjusting for covariates and after also adjusting for insulin use for users with T2D (all P<.05). CONCLUSIONS: People with T1D and T2D reported a 1.07% to 1.27% absolute reduction in HbA1c during a median 4 months of using the One Drop | Mobile app. Using the app to track self-care was associated with improved HbA1c. More research is needed on the health benefits of publicly available diabetes apps, particularly studies associating app engagement with short- and long-term effects. PMID- 30291060 TI - The Effect of Telehealth on Quality of Life and Psychological Outcomes Over a 12 Month Period in a Diabetes Cohort Within the Whole Systems Demonstrator Cluster Randomized Trial. AB - BACKGROUND: Much is written about the promise of telehealth and there is great enthusiasm about its potential. However, many studies of telehealth do not meet orthodox quality standards and there are few studies examining quality of life in diabetes as an outcome. OBJECTIVE: To assess the impact of home-based telehealth (remote monitoring of physiological, symptom and self-care behavior data for long term conditions) on generic and disease-specific health-related quality of life, anxiety, and depressive symptoms over 12 months in patients with diabetes. Remote monitoring provides the potential to improve quality of life, through the reassurance it provides patients. METHODS: The study focused on participant reported outcomes of patients with diabetes within the Whole Systems Demonstrator (WSD) Telehealth Questionnaire Study, nested within a pragmatic cluster randomized trial of telehealth (the WSD Telehealth Trial), held across 3 regions of England. Telehealth was compared with usual-care, with general practice as the unit of randomization. Participant-reported outcome measures (Short-Form 12, EuroQual-5D, Diabetes Health Profile scales, Brief State-Trait Anxiety Inventory, and Centre for Epidemiological Studies Depression Scale) were collected at baseline, short-term (4 months) and long-term (12months) follow-ups. Intention-to treat analyses testing treatment effectiveness, were conducted using multilevel models controlling for practice clustering and a range of covariates. Analyses assumed participants received their allocated treatment and were conducted for participants who completed the baseline plus at least one follow-up assessment (n=317). RESULTS: Primary analyses showed differences between telehealth and usual care were small and only reached significance for 1 scale (diabetes health profile-disinhibited eating, P=.006). The magnitude of differences between trial arms did not reach the trial-defined minimal clinically important difference of 0.3 standard deviations for most outcomes. Effect sizes (Hedge's g) ranged from 0.015 to 0.143 for Generic quality of life (QoL) measures and 0.018 to 0.394 for disease specific measures. CONCLUSIONS: Second generation home-based telehealth as implemented in the WSD evaluation was not effective in the subsample of people with diabetes. Overall, telehealth did not improve or have a deleterious effect quality of life or psychological outcomes for patients with diabetes over a 12 month period. PMID- 30291061 TI - The Value of Children's Voices for a Video Game Development in the Context of Type 1 Diabetes: Focus Group Study. AB - BACKGROUND: Children with type 1 diabetes mellitus (T1DM) face daily challenges performing self-care tasks, controlling symptoms, and dealing with psychosocial issues. The use of video games to improve health is a successful support for persons with chronic diseases, promoting adequate self-management through simulations of real life. Involving future users in the development of games is essential to generating innovative, creative, and effective programs. OBJECTIVE: Our goal is to identify what children with T1DM need to know about their disease and their self-care tasks as well as their preferences in video games. METHODS: Children with T1DM provided input about their learning needs, self-care tasks, and preferences in video games. Three categories were identified through qualitative content analysis: dealing with emotions and knowledge, practical skills and awareness, and game preferences. RESULTS: Children expressed concerns about the difficulties of self-care, lack of knowledge about diabetes, and lack of awareness about the consequences of behaviors related to self-care, which contribute to inappropriate behaviors and significantly impact self-management of their disease. They expressed enthusiasm for a video game for children with diabetes that considered their needs and preferences. CONCLUSIONS: Findings support the potential benefits when children's input is considered in game design. Consideration of customer needs and preferences is a powerful resource in the development of video games with enhanced learning experience. PMID- 30291062 TI - A Novel Intervention Including Individualized Nutritional Recommendations Reduces Hemoglobin A1c Level, Medication Use, and Weight in Type 2 Diabetes. AB - BACKGROUND: Type 2 diabetes (T2D) is typically managed with a reduced fat diet plus glucose-lowering medications, the latter often promoting weight gain. OBJECTIVE: We evaluated whether individuals with T2D could be taught by either on site group or remote means to sustain adequate carbohydrate restriction to achieve nutritional ketosis as part of a comprehensive intervention, thereby improving glycemic control, decreasing medication use, and allowing clinically relevant weight loss. METHODS: This study was a nonrandomized, parallel arm, outpatient intervention. Adults with T2D (N=262; mean age 54, SD 8, years; mean body mass index 41, SD 8, kg.m-2; 66.8% (175/262) women) were enrolled in an outpatient protocol providing intensive nutrition and behavioral counseling, digital coaching and education platform, and physician-guided medication management. A total of 238 participants completed the first 10 weeks. Body weight, capillary blood glucose, and beta-hydroxybutyrate (BOHB) levels were recorded daily using a mobile interface. Hemoglobin A1c (HbA1c) and related biomarkers of T2D were evaluated at baseline and 10-week follow-up. RESULTS: Baseline HbA1c level was 7.6% (SD 1.5%) and only 52/262 (19.8%) participants had an HbA1c level of <6.5%. After 10 weeks, HbA1c level was reduced by 1.0% (SD 1.1%; 95% CI 0.9% to 1.1%, P<.001), and the percentage of individuals with an HbA1c level of <6.5% increased to 56.1% (147/262). The majority of participants (234/262, 89.3%) were taking at least one diabetes medication at baseline. By 10 weeks, 133/234 (56.8%) individuals had one or more diabetes medications reduced or eliminated. At follow-up, 47.7% of participants (125/262) achieved an HbA1c level of <6.5% while taking metformin only (n=86) or no diabetes medications (n=39). Mean body mass reduction was 7.2% (SD 3.7%; 95% CI 5.8% to 7.7%, P<.001) from baseline (117, SD 26, kg). Mean BOHB over 10 weeks was 0.6 (SD 0.6) mmol.L-1 indicating consistent carbohydrate restriction. Post hoc comparison of the remote versus on-site means of education revealed no effect of delivery method on change in HbA1c (F1,260=1.503, P=.22). CONCLUSIONS: These initial results indicate that an individualized program delivered and supported remotely that incorporates nutritional ketosis can be highly effective in improving glycemic control and weight loss in adults with T2D while significantly decreasing medication use. PMID- 30291063 TI - Improving Glycemic Control With a Standardized Text-Message and Phone-Based Intervention: A Community Implementation. AB - BACKGROUND: Type II diabetes mellitus (T2DM) presents a major disease burden in the United States. Outpatient glycemic control among patients with T2DM remains difficult. Telemedicine shows great potential as an adjunct therapy to aid in glycemic control in real-world settings. OBJECTIVE: We aimed to explore the effectiveness of EpxDiabetes, a novel digital health intervention, in improving hemoglobin A1c (HbA1c) and fasting blood glucose (FBG) among patients with uncontrolled diabetes. METHODS: We recruited 396 patients from a community clinic in St. Louis, Missouri, from a database of patients diagnosed with T2DM and with a most recent HbA1c >7% as part of a quality improvement project. An automated call or text-messaging system was used to monitor patient-reported FBG. If determined to be elevated, care managers were notified by email, text, or electronic medical record alert. Participants self-reported their FBG data by replying to EpxDiabetes automated phone calls or text messages. Data were subsequently analyzed, triaged, and shared with providers to enable appropriate follow-up and care plan adjustments. Absolute HbA1c reduction, patient engagement, and absolute patient-reported FBG reduction were examined at approximately 6 months post implementation. RESULTS: EpxDiabetes had an average 95.6% patient response rate to messages at least once per month and an average 71.1% response rate to messages at least once per week. Subsequent HbA1c drop with EpxDiabetes use over 4 months was -1.15% (95% CI -1.58 to -0.71) for patients with HbA1c >8% at baseline compared to the change in HbA1c over 4 months prior to the implementation of EpxDiabetes of only -0.005 points (95% CI -0.28 to 0.27), P=.0018. CONCLUSIONS: EpxDiabetes may help reduce HbA1c in patients with high HbA1c baselines (>8%). The intervention demonstrates high patient engagement sustainable for at least 6 months. PMID- 30291064 TI - Impact of Facebook on Glucose Control in Type 1 Diabetes: A Three-Year Cohort Study. AB - BACKGROUND: As the world is changing, traditional health care services should be adapted for the new era of technology and the Internet. One of the possible ways for communication between health care providers and patients is social media. There are several benefits of social media in health: increased interactions with others; more available and shared information; increased accessibility; social or emotional support. OBJECTIVE: The aim of this study was to evaluate the results of Facebook and CareLink software as a possible Internet tool to improve diabetes control in type 1 diabetes patients using a sensor augmented pump. METHODS: A total of 67 adolescents with type 1 diabetes and in the age range of 14-23 years were randomized in 2 groups: (1) Traditional group and (2) Internet group. In the traditional group, 34 patients were treated using standard medical protocol with regular clinic visits, where data were uploaded at the clinic and interventions (pump settings-basal bolus insulin and education) were delivered to the patient. In the Internet group, 33 patients were treated using Facebook and CareLink software (Medtronic Diabetes) on a monthly basis, where the data were uploaded by the patient at home and interventions (same as traditional group) were delivered via Facebook (written reports and chats). Both the traditional and Internet group had regular visits every 3 months with standard medical protocol. Glycosylated hemoglobin (HbA1c) was obtained before and every 3 months during the study for a 3-year-period. RESULTS: The improvement in glucose control was found in both groups: 7.9% (SD 1.4) [62.8 mmol/mol (SD 12.9)] to 6.9% (SD 1.2) [51.9 mmol/mol (SD 10.8)] in the traditional group, and 7.8% (SD 1.8) [61.7 mmol/mol (SD 17.2)] to 6.7% (SD 1.8) [49.7 mmol/mol (SD 17.3)] in the Internet group). Significant improvement of HbA1c (P<.05) was found in favor of the Internet group. CONCLUSIONS: Social media such as Facebook as a tool can assist in standard medical care to improve glucose control in a long term period in adolescents with type 1 diabetes using insulin pump therapy. PMID- 30291065 TI - Examining the Impact of a Novel Blood Glucose Monitor With Color Range Indicator on Decision-Making in Patients With Type 1 and Type 2 Diabetes and its Association With Patient Numeracy Level. AB - BACKGROUND: Many patients struggle to interpret and respond appropriately to the numerical blood glucose results displayed on their meter, with many regularly taking no action or self-care adjustment for out-of-range results. We recently reported that a glucose meter that provides automatic onscreen information using a color range indicator (ColorSure Technology) improved the ability of patients to categorize their blood glucose results. OBJECTIVE: The objective of this study was to examine how ColorSure Technology (or color) affected patient decision making on blood glucose results and how patient numeracy levels influenced such decisions. METHODS: We invited 103 subjects (56 with type 2 diabetes and 47 with type 1 diabetes) to a face-to-face in-clinic visit in a diabetes care center and showed them glucose results with or without color via interactive computer or paper logbook exercises. Before participating in these exercises, subjects completed surveys on numeracy and their understanding of blood glucose information. RESULTS: Subjects preferentially acted on high glucose results shown with color (55%, 57/103) compared to results without color (45%, 46/103; P=.001). When shown identical pairs of results, subjects preferentially acted on results shown with color (62%, 64/103) compared to results without color (16%, 16/103) (P<.001). Subjects more accurately identified days of the week in which results were low, in range, or high when reviewing logbooks with color (83%, 85/103) than without color (68%, 70/103; P=.012). Subjects with lower numeracy were more likely to consider taking action for high glucose results shown with color (59%, 18/31) than without color (41%, 13/31) and preferentially would take action on results shown with color (71%, 22/31) compared to results without color (16%, 5/31). CONCLUSIONS: Insulin- and noninsulin-using subjects were each more inclined to act when glucose results were shown with color, and associating glucose results with color was viewed as particularly beneficial by subjects with lower numeracy. PMID- 30291066 TI - How's Your Sugar? Evaluation of a Website for Aboriginal People With Diabetes. AB - BACKGROUND: Australia's Aboriginal and Torres Strait Islander peoples (hereafter referred to as "Aboriginal people") have the longest continuing culture in the world, living sustainably for at least 65,000 years on the Australian continent. In relatively recent times, colonization processes have resulted in Aboriginal people experiencing unacceptable health inequalities compared with other Australians. One disease introduced due to colonization is diabetes, the second leading cause of death for Aboriginal peoples. OBJECTIVES: The objective of this study was to describe the construction and utilization of the website "How's Your Sugar, " a website for Aboriginal people with type 2 diabetes (herein after referred to as diabetes). The questions for the evaluation were as follows: how was the website constructed; did target groups utilize the website; and did engagement with the website improve diabetes management. METHODS: A mixed-method study design was employed. A content analysis of project documents provided information about the website construction. Data from Google analytics provided information about website utilization. To describe patterns of website sessions, percentages and numbers were calculated. A voluntary survey provided more information on website utilization and diabetes self-management. Percentage, numbers, and 95% CIs were calculated for each variable. A chi-square test was performed for Aboriginal status, age, gender, and Aboriginal diabetic status using Australian population estimates and Aboriginal diabetes rates. RESULTS: The website development drew on Aboriginal health, social marketing, interactive health promotion frameworks, as well as evidence for diabetes self-management. The website build involved a multidisciplinary team and participation of Aboriginal diabetics, Aboriginal diabetic family members, and Aboriginal health workers. This participation allowed for inclusion of Aboriginal ways of knowing and being. The highest number of website sessions came from Australia, 98.15% (47,717/48,617) and within Australia, Victoria 50.97% (24,323/47,717). There were 129 survey respondents, and the distribution had more female, 82.9% (107/129, 95% CI 76-88), Aboriginal, 21.7% (28/129, 95% CI 16-30), and Aboriginal diabetic, 48% (13/27, 95% CI 31-66) respondents than expected with P<.001 for these three groups. Most common reasons for visits were university assignment research, 40.6% (41/101), and health workers looking for information, 20.8% (21/101). The sample size was too small to calculate diabetes self-management change. CONCLUSIONS: Inclusion of Aboriginal ways of knowing and being alongside other theoretical and evidence models in Web design is possible. Aboriginal people do utilize Web-based health promotion, and further understanding about reaching to this population would be of use. Provision of an education resource would likely have enhanced educational engagement. Web-based technologies are rapidly evolving, and these can potentially measure behavior change in engaging ways that also have benefits for the participant. A challenge for designers is inclusivity of cultural diversity for self-determination. PMID- 30291067 TI - Mutual Involvement in Families With Type 2 Diabetes Through Web-Based Health Care Solutions: Quantitative Survey Study of Family Preferences, Challenges, and Potentials. AB - BACKGROUND: Type 2 diabetes (T2D) is a prevalent chronic disease that affects not just patients but entire families. Both the patient and the rest of the family may benefit from gaining knowledge about the disease and from supportive interfamilial interaction. The Internet is becoming a widely-used resource for health information, so a Web-based solution could potentially promote awareness and knowledge on how to manage T2D as a family, while also providing support for the family. OBJECTIVE: We aim to assess the usage of online diabetes information by patients with T2D and their relatives, and explore the families' needs and preferences regarding online information on diabetes. METHODS: A quantitative self-reported questionnaire survey was performed with Danish families that had at least one family member diagnosed with T2D. The survey consisted of 36 closed questions on demographics, usage of the Internet, preferences in the source of information, interest in online information on six problem domains within family life related to T2D, preferences towards the delivery format of online information, and peer-to-peer communication. Two open-ended questions were also included to elicit any additional comments or suggestions about improving online information on T2D regarding family life. RESULTS: Fifty participants from 22 families with T2D answered the questionnaire individually. Relatives (25/28, 89%) and patients (22/22, 100%) indicated that information on T2D is relevant for them, while indicating that the Internet is the first or second preferred source when in need of information on T2D (25/28, 89% vs 21/22, 95%). Only a minority of the participants indicated that they had searched the Internet to gain knowledge on T2D regarding family life (9/28, 32% vs 10/22, 46%). Also, patients were more likely to have used the Internet to gain information on T2D (P=.027). Both groups indicated a preference for watching videos or reading about T2D in relation to family life while a minority of the participants indicated an interest in peer-to peer communication. Regarding the six problem domains, the domains Support, Knowledge, and Everyday Life were slightly more popular. These three domains were considered interesting by at least 79% (22/28) and 73% (16/22) of the relatives and patients respectively, while the domains Communication, Worries, and Roles were considered interesting by at least 46% (20/28) and 50% (11/22). CONCLUSIONS: Despite an interest in online information on T2D, there appears to be an unsatisfied need for more supportive online information on T2D aimed at Danish families with T2D. Based on family preferences, online information should focus on the six problem domains and be presented through text and videos by health care practitioners and peers. Peer-to-peer communication elements may be beneficial, but are only expected to be used by a very limited number of families. PMID- 30291068 TI - A Feasible and Efficacious Mobile-Phone Based Lifestyle Intervention for Filipino Americans with Type 2 Diabetes: Randomized Controlled Trial. AB - BACKGROUND: Filipino Americans have a high prevalence of obesity, type 2 diabetes (T2D), and cardiovascular disease compared with other Asian American subgroups and non-Hispanic whites. Mobile health (mHealth) weight loss interventions can reduce chronic disease risks, but these are untested in Filipino Americans with T2D. OBJECTIVE: The objective of this study was to assess feasibility and potential efficacy of a pilot, randomized controlled trial (RCT) of a culturally adapted mHealth weight loss lifestyle intervention (Pilipino Americans Go4Health [PilAm Go4Health]) for overweight Filipino Americans with T2D. METHODS: This was a 2-arm pilot RCT of the 3-month PilAm Go4Health intervention (phase 1) with an active waitlist control and 3-month follow-up (phase 2). The waitlist control received the PilAm Go4Health in phase 2, whereas the intervention group transitioned to the 3-month follow-up. PilAm Go4Health incorporated a Fitbit accelerometer, mobile app with diary for health behavior tracking (steps, food/calories, and weight), and social media (Facebook) for virtual social support, including 7 in-person monthly meetings. Filipino American adults >=18 years with T2D were recruited from Northern California. Feasibility was measured by rates of recruitment, engagement, and retention. Multilevel regression analyses assessed within and between group differences for the secondary outcome of percent weight change and other outcomes of weight (kg), body mass index (BMI), waist circumference, fasting plasma glucose, HbA1c, and steps. RESULTS: A total of 45 Filipino American adults were enrolled and randomized. Mean age was 58 (SD 10) years, 62% (28/45) were women, and mean BMI was 30.1 (SD 4.6). Participant retention and study completion were 100%, with both the intervention and waitlist group achieving near-perfect attendance at all 7 intervention office visits. Groups receiving the PilAm Go4Health in phase 1 (intervention group) and phase 2 (waitlist group) had significantly greater weight loss, -2.6% (-3.9 to 1.4) and -3.3% (-1.8 to -4.8), respectively, compared with the nonintervention group, resulting in a moderate to small effect sizes (d=0.53 and 0.37, respectively). In phase 1, 18% (4/22) of the intervention group achieved a 5% weight loss, whereas 82% (18/22) maintained or lost 2% to 5% of their weight and continued to maintain this weight loss in the 3-month follow-up. Other health outcomes, including waist circumference, BMI, and step counts, improved when each arm received the PilAm Go4Health, but the fasting glucose and HbA1c outcomes were mixed. CONCLUSIONS: The PilAm Go4Health was feasible and demonstrated potential efficacy in reducing diabetes risks in overweight Filipino Americans with T2D. This study supports the use of mHealth and other promising intervention strategies to reduce obesity and diabetes risks in Filipino Americans. Further testing in a full-scale RCT is warranted. These findings may support intervention translation to reduce diabetes risks in other at-risk diverse populations. TRIAL REGISTRATION: Clinicaltrials.gov NCT02290184; https://clinicaltrials.gov/ct2/show/NCT02290184 (Archived by WebCite at http://www.webcitation.org/6vDfrvIPp). PMID- 30291069 TI - New-Onset Diabetes Educator to Educate Children and Their Caregivers About Diabetes at the Time of Diagnosis: Usability Study. AB - BACKGROUND: Diabetes self-management education is essential at the time of diagnosis. We developed the New-Onset Diabetes Educator (NODE), an animation based educational web application for type 1 diabetes mellitus patients. OBJECTIVE: Our hypothesis is that NODE is a feasible, effective and user-friendly intervention in improving diabetes self-management education delivery to child/caregiver-dyads at the time of diagnosis. METHODS: We used a pragmatic parallel randomized trial design. Dyads were recruited within 48 hours of diagnosis and randomized into a NODE-enhanced diabetes self-management education or a standard diabetes self-management education group. Dyads randomized in the NODE group received the intervention on an iPad before receiving the standard diabetes self-management education with a nurse educator. The Diabetes Knowledge Test 2 assessed disease-specific knowledge pre- and postintervention in both groups, and was compared using t tests. Usability of the NODE mobile health intervention was assessed in the NODE group. RESULTS: We recruited 16 dyads (mean child age 10.75, SD 3.44). Mean Diabetes Knowledge Test 2 scores were 14.25 (SD 4.17) and 18.13 (SD 2.17) pre- and postintervention in the NODE group, and 15.50 (SD 2.67) and 17.38 (SD 2.26) in the standard diabetes self-management education group. The effect size was medium (Delta=0.56). Usability ratings of NODE were excellent. CONCLUSIONS: NODE is a feasible mobile health strategy for type 1 diabetes education. It has the potential to be an effective and scalable tool to enhance diabetes self-management education at time of diagnosis, and consequently, could lead to improved long-term clinical outcomes for patients living with the disease. PMID- 30291070 TI - Mobile App for Simplifying Life With Diabetes: Technical Description and Usability Study of GlucoMan. AB - BACKGROUND: Patients with diabetes can be affected by several comorbidities that require immediate action when occurring as they may otherwise cause fatal or consequential damage. For this reason, patients must closely monitor their metabolism and inject insulin when necessary. The documentation of glucose values and other relevant measurements is often still on paper in a diabetes diary. OBJECTIVE: The goal of this work is to develop and implement a novel mobile health system for the secure collection of relevant data referring to a person's metabolis and to digitize the diabetes diary to enable continuous monitoring for both patients and treating physicians. One specific subgoal is to enable data transmission of health parameters to secure data storage. METHODS: The process of implementing the system consists of (1) requirements analysis with patients and physicians to identify patient needs and specify relevant functionalities, (2) design and development of the app and the data transmission, and (3) usability study. RESULTS: We developed and implemented the mobile app GlucoMan to support data collection pertaining to a person's metabolism. An automated transfer of measured values from a glucometer was implemented. Medication and nutrition data could be entered using product barcodes. Relevant background knowledge such as information on carbohydrates was collected from existing databases. The recorded data was transmitted using international interoperability standards to the MIDATA.coop storage platform. The usability study revealed some design issues that needs to be solved, but in principle, the study results show that the app is easy to use and provides useful features. CONCLUSIONS: Data collection on a patient's metabolism can be supported with a multifunctional app such as GlucoMan. Besides monitoring, continuous data can be documented and made available to the treating physician. GlucoMan allows patients to monitor disease relevant parameters and decide who accesses their health data. In this way, patients are empowered not only to manage diabetes but also manage their health data. PMID- 30291071 TI - Health Care Professionals' Clinical Perspectives on Glycemic Control and Satisfaction With a New Blood Glucose Meter With a Color Range Indicator: Online Evaluation in India, Russia, China, and the United States. AB - BACKGROUND: We previously demonstrated in patients with diabetes that displaying blood glucose results in association with color improved their ability to interpret glucose results. OBJECTIVE: The objective of this study was to investigate the perceptions of health care professionals (HCPs) in specific countries about the value of color on a new glucose meter and to determine if HCP perspectives among countries differ on the value of this approach in clinical practice. METHODS: A total of 180 HCPs, including 105 endocrinologists, 34 primary care physicians, 25 diabetes educators, and 16 pharmacists, were recruited from India (n=50), Russia (n=50), China (n=50), and the United States (n=30). These HCPs experienced the OneTouch Select Plus Simple glucose meter online from their own office computer using interactive demonstrations (webpages, meter simulator, and video clips). After providing demographic and current clinical practice insights, HCPs responded to questions about the utility of the color-enhanced glucose meter. RESULTS: Mean age and years in their current professional role for the 180 HCPs was 41.3 (SD 8.1) and 13.3 (SD 6.8) years for endocrinologists, 41.3 (SD 8.3) and 14.1 (SD 6.8) years for primary care physicians, 37.5 (SD 8.7) and 12.7 (SD 6.8) years for diabetes educators, and 35.9 (SD 5.3) and 9.5 (SD 5.2) years for pharmacists. In all, 88% (44/50) of Russian and 83% (25/30) of American HCPs said their patients find it easy to recognize low, in-range, or high blood glucose results compared to 56% (28/50) of HCPs in China and 42% (21/50) in India. Regardless of country, HCPs had less confidence that their patients act on blood glucose results with 52% (26/50) in Russia, 63% (19/30) in the United States, 60% (30/50) in China, and 40% (20/50) in India responding positively. During the interactive online meter experience, HCPs from all countries responded positively to questions about a meter with color features. After reflecting on the value of this meter, most HCPs strongly agreed or agreed their patients would be more inclined to act on results using a meter with color features (Russia: 92%, 46/50; United States: 70%, 21/30; China: 98%, 49/50; India: 94%, 47/50). They also said that color was particularly useful for patients with lower numeracy or education who may struggle with interpreting results (Russia: 98%, 49/50; United States: 77%, 23/30; China: 100%, 50/50; India: 82%, 41/50). CONCLUSIONS: This multicountry online study provides evidence that HCPs had high overall satisfaction with the OneTouch Select Plus glucose meter, which uses color-coded information to assist patients with interpreting blood glucose results. This may be especially helpful in patient populations with low numeracy or literacy and limited access to health care and direct interaction with HCPs. PMID- 30291072 TI - Assessing Diabetes-Relevant Data Provided by Undergraduate and Crowdsourced Web Based Survey Participants for Honesty and Accuracy. AB - BACKGROUND: To eliminate health disparities, research will depend on our ability to reach select groups of people (eg, samples of a particular racial or ethnic group with a particular disease); unfortunately, researchers often experience difficulty obtaining high-quality data from samples of sufficient size. OBJECTIVE: Past studies utilizing MTurk applaud its diversity, so our initial objective was to capitalize on MTurk's diversity to investigate psychosocial factors related to diabetes self-care. METHODS: In Study 1, a "Health Survey" was posted on MTurk to examine diabetes-relevant psychosocial factors. The survey was restricted to individuals who were 18 years of age or older with diabetes. Detection of irregularities in the data, however, prompted an evaluation of the quality of MTurk health-relevant data. This ultimately led to Study 2, which utilized an alert statement to improve conscientious behavior, or the likelihood that participants would be thorough and diligent in their responses. Trap questions were also embedded to assess conscientious behavior. RESULTS: In Study 1, of 4165 responses, 1246 were generated from 533 unique IP addresses completing the survey multiple times within close temporal proximity. Ultimately, only 252 responses were found to be acceptable. Further analyses indicated additional quality concerns with this subsample. In Study 2, as compared with the MTurk sample (N=316), the undergraduate sample (N=300) included more females, and fewer individuals who were married. The samples did not differ with respect to race. Although the presence of an alert resulted in fewer trap failures (mean=0.07) than when no alert was present (mean=0.11), this difference failed to reach significance: F1,604=2.5, P=.11, n2=.004, power=.35. The modal trap failure response was zero, while the mean was 0.092 (SD=0.32). There were a total of 60 trap failures in a context where the potential could have exceeded 16,000. CONCLUSIONS: Published studies that utilize MTurk participants are rapidly appearing in the health domain. While MTurk may have the potential to be more diverse than an undergraduate sample, our efforts did not meet the criteria for what would constitute a diverse sample in and of itself. Because some researchers have experienced successful data collection on MTurk, while others report disastrous results, Kees et al recently identified that one essential area of research is of the types and magnitude of cheating behavior occurring on Web based platforms. The present studies can contribute to this dialogue, and alternately provide evidence of disaster and success. Moving forward, it is recommended that researchers employ best practices in survey design and deliberately embed trap questions to assess participant behavior. We would strongly suggest that standards be in place for publishing the results of Web based surveys-standards that protect against publication unless there are suitable quality assurance tests built into the survey design, distribution, and analysis. PMID- 30291073 TI - A Novel Approach to Identifying Barriers and Facilitators in Raising a Child With Type 1 Diabetes: Qualitative Analysis of Caregiver Blogs. AB - BACKGROUND: With rising incidence of type 1 diabetes (T1D) diagnoses among children and the high levels of distress experienced by the caregivers of these children, caregiver support is becoming increasingly important. Historically, relatively few support resources have existed. Increasing use of the Internet, and blogs in particular, has seen a growth of peer support between caregivers of children with T1D. However, little is known about the type and quality of information shared on T1D caregiver blogs. At the same time, the information on such blogs offers a new window into what challenges and successes caregivers experience in helping to manage their children's T1D. OBJECTIVE: The purpose of this study was to (1) analyze blogs of caregivers to children with T1D to better understand the challenges and successes they face in raising a child with T1D, and (2) assess the blogs for the presence of unsafe or inaccurate clinical information or advice. METHODS: An inductive thematic qualitative study was conducted of three blogs authored by caregivers of children living with T1D, which included 140 unique blog posts and 663 associated comments. Two physician investigators evaluated the blogs for presence of clinical or medical misinformation. RESULTS: Five major themes emerged: (1) the impact of the child's diagnosis, (2) the burden of intense self-management experienced in caring for a child with T1D, (3) caregivers' use of technology to ease their fear of hypoglycemia and impacts that device alarms associated with this technology have on caregiver burden, (4) caregivers' perceptions of frequently missed or delayed diagnosis of T1D and the frustration this causes, and (5) the resilience that caregivers develop despite the burdens they experience. Misinformation was exceedingly rare and benign when it did occur. CONCLUSIONS: Blog analysis represents a novel approach to understand the T1D caregiver's experience. This qualitative study found many challenges that caregivers face in raising a child with T1D. Despite the many barriers caregivers face in managing their children's T1D, they find support through advocacy efforts and peer-to-peer blogging. Blogs provide a unique avenue for support, with only rare and benign findings of medical misinformation, and may be a resource that diabetes care providers can consider offering to families for support. PMID- 30291074 TI - Change in Glycemic Control With Use of a Digital Therapeutic in Adults With Type 2 Diabetes: Cohort Study. AB - BACKGROUND: Intensive lifestyle change can treat and even reverse type 2 diabetes. Digital therapeutics have the potential to deliver lifestyle as medicine for diabetes at scale. OBJECTIVE: This 12-week study investigates the effects of a novel digital therapeutic, FareWell, on hemoglobin A1c (HbA1c) and diabetes medication use. METHODS: Adults with type 2 diabetes and a mobile phone were recruited throughout the United States using Facebook advertisements. The intervention aim was to effect a sustainable shift to a plant-based dietary pattern and regular exercise by advancing culinary literacy and lifestyle skill acquisition. The intervention was delivered by an app paired with specialized human support, also delivered digitally. Health coaching was provided every 2 weeks by telephone, and a clinical team was available for participants requiring additional support. Participants self-reported current medications and HbA1c at the beginning and end of the 12-week program. Self-efficacy related to managing diabetes and maintaining dietary changes was assessed via survey. Engagement was recorded automatically through the app. RESULTS: We enrolled 118 participants with a baseline HbA1c >6.5%. Participants were 81.4% female (96/118) and resided in 38 US states with a mean age of 50.7 (SD 9.4) years, baseline body mass index of 38.1 (SD 8.8) kg/m2, and baseline HbA1c of 8.1% (SD 1.6). At 12 weeks, 86.2% (94/109) of participants were still using the app. Mean change in HbA1c was -0.8% (97/101, SD 1.3, P<.001) for those reporting end-study data. For participants with a baseline HbA1c >7.0% who did not change medications midstudy, HbA1c change was -1.1% (67/69, SD 1.4, P<.001). The proportion of participants with an end study HbA1c <6.5% was 28% (22/97). After completion of the intervention, 17% (16/97) of participants reported a decrease in diabetic medication while 8% (8/97) reported an increase. A total of 57% (55/97) of participants achieved a composite outcome of reducing HbA1c, reducing diabetic medication use, or both; 92% (90/98) reported greater confidence in their ability to manage their diabetes compared to before the program, and 91% (89/98) reported greater confidence in their ability to maintain a healthy dietary pattern. Participants engaged with the app an average of 4.3 times per day. We observed a significantly greater decrease in HbA1c among participants in the highest tertile of app engagement compared to those in the lowest tertile of app engagement (P=.03). CONCLUSIONS: Clinically meaningful reductions in HbA1c were observed with use of the FareWell digital therapeutic. Greater glycemic control was observed with increasing app engagement. Engagement and retention were both high in this widely distributed sample. PMID- 30291075 TI - Perceptions of Persons With Type 2 Diabetes Treated in Swedish Primary Health Care: Qualitative Study on Using eHealth Services for Self-Management Support. AB - BACKGROUND: Digital health services are increasing rapidly worldwide. Strategies to involve patients in self-monitoring of type 2 diabetes (T2D) on a daily basis is of crucial importance, and there is a need to optimize the delivery of care such as self-management support. Digitalized solutions have the potential to modify and personalize the way in which people use primary health services, both by increasing access to information and providing other forms of support at a distance. It is a challenge to integrate core values of person-centered care into digitalized health care services. OBJECTIVE: The objective of this study was to describe perceptions of using electronic health (eHealth) services and related technologies for self-management support among people with T2D treated in Swedish primary health care. METHODS: This is a qualitative study based on interviews analyzed using qualitative content analysis conducted among people diagnosed with T2D. RESULTS: Findings suggest that the participants had mixed feelings regarding the use of digital health services for self-management support. They experienced potentials such as increased involvement, empowerment, and security, as well as concerns such as ambivalence and uncertainty. CONCLUSIONS: Digital health services for self-management are easily accessible and have the potential to reach a wide population. However, targeted training to increase digital skills is required, and personalized devices must be adapted and become more person centered to improve patients' involvement in their own care. PMID- 30291076 TI - Transitional Needs of Australian Young Adults With Type 1 Diabetes: Mixed Methods Study. AB - BACKGROUND: Young adulthood is marked by transitions that impact diabetes self management behaviors, which require ongoing diabetes education and support. Traditional diabetes education programs and services currently do not meet the needs of many young adults with type 1 diabetes mellitus (T1DM) as they continue to fall through the cracks of clinical services. Age-centered diabetes education programs and services present an opportunity for young adults to meet in a supportive environment and gain a better understanding about diabetes management. OBJECTIVE: The aim of the study was to identify the health and well-being needs of Australian young adults aged between 18 and 35 years with T1DM to develop appropriate solutions to keep them engaged with diabetes self-management. METHODS: In total, 13 semistructured individual interviews and self-reported surveys were obtained to understand participants' experiences with diabetes education programs and services. Together with survey data, transcribed interviews were analyzed into themes and categories using comparative analysis to identify the health and well-being needs of young adults with T1DM during young adulthood. RESULTS: Diabetes education and service needs for young adults with T1DM related to improving access to existing diabetes education programs and services, having credible informational resources, as well as having personalized diabetes management advice. Participants especially valued relevant and real-time information and opportunities for peer support, mostly sourced from Web-based platforms. CONCLUSIONS: There is a need for diabetes education programs and services to be age-appropriate and easily accessible, to provide relevant and credible information, and to provide opportunities for peer support to better support young adults with T1DM. These findings also support the use of diabetes education programs or services delivered online through mHealth systems in this population. PMID- 30291077 TI - An Interactive Simulation to Change Outcome Expectancies and Intentions in Adults With Type 2 Diabetes: Within-Subjects Experiment. AB - BACKGROUND: Computerized simulations are underutilized to educate or motivate patients with chronic disease. OBJECTIVE: The aim of this study was to test the efficacy of an interactive, personalized simulation that demonstrates the acute effect of physical activity on blood glucose. Our goal was to test its effects on physical activity-related outcome expectancies and behavioral intentions among adults with type 2 diabetes mellitus (T2DM). METHODS: In this within-subjects experiment, potential participants were emailed a link to the study website and directed through 7 tasks: (1) consent; (2) demographics, baseline intentions, and self-reported walking; (3) orientation to the diurnal glucose curve; (4) baseline outcome expectancy, measured by a novel drawing task in which participants use their mouse to draw the expected difference in the diurnal glucose curve if they had walked; (5) interactive simulation; (6) postsimulation outcome expectancy measured by a second drawing task; and (7) final measures of intentions and impressions of the website. To test our primary hypothesis that participants' outcome expectancies regarding walking would shift toward the outcome presented in the interactive simulation, we used a paired t test to compare the difference of differences between the change in area under the curve in the simulation and participants' two drawings. To test whether intentions to walk increased, we used paired t tests. To assess the intervention's usability, we collected both quantitative and qualitative data on participants' perceptions of the drawing tasks and simulation. RESULTS: A total of 2019 individuals visited the website and 1335 (566 males, 765 females, and 4 others) provided complete data. Participants were largely late middle-aged (mean=59.8 years; standard deviation=10.5), female 56.55% (755/1335), Caucasian 77.45% (1034/1335), lower income 64.04% (855/1335) t1334=3.4, P <=.001). Our second hypothesis, that participants' intentions to walk in the coming week would increase, was also supported; general intention (mean difference=0.31/7, t1001=10.8, P<.001) and minutes of walking last week versus planned for coming week (mean difference=33.5 min, t1334=13.2, P<.001) both increased. Finally, an examination of qualitative feedback and drawing task data suggested that some participants had difficulty understanding the website. This led to a post-hoc subset analysis. In this analysis, effects for our hypothesis regarding outcome expectancies were markedly stronger, suggesting that further work is needed to determine moderators of the efficacy of this simulation. CONCLUSIONS: A novel interactive simulation is efficacious in changing the outcome expectancies and behavioral intentions of adults with T2DM. We discuss applications of our results to the design of mobile health (mHealth) interventions. PMID- 30291078 TI - Models Used in Clinical Decision Support Systems Supporting Healthcare Professionals Treating Chronic Wounds: Systematic Literature Review. AB - BACKGROUND: Chronic wounds such as diabetic foot ulcers, venous leg ulcers, and pressure ulcers are a massive burden to health care facilities. Many randomized controlled trials on different wound care elements have been conducted and published in the Cochrane Library, all of which have only a low evidential basis. Thus, health care professionals are forced to rely on their own experience when making decisions regarding wound care. To progress from experience-based practice to evidence-based wound care practice, clinical decision support systems (CDSS) that help health care providers with decision-making in a clinical workflow have been developed. These systems have proven useful in many areas of the health care sector, partly because they have increased the quality of care, and partially because they have generated a solid basis for evidence-based practice. However, no systematic reviews focus on CDSS within the field of wound care to chronic wounds. OBJECTIVE: The aims of this systematic literature review are (1) to identify models used in CDSS that support health care professionals treating chronic wounds, and (2) to classify each clinical decision support model according to selected variables and to create an overview. METHODS: A systematic review was conducted using 6 databases. This systematic literature review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement for systematic reviews. The search strategy consisted of three facets, respectively: Facet 1 (Algorithm), Facet 2 (Wound care) and Facet 3 (Clinical decision support system). Studies based on acute wounds or trauma were excluded. Similarly, studies that presented guidelines, protocols and instructions were excluded, since they do not require progression along an active chain of reasoning from the clinicians, just their focus. Finally, studies were excluded if they had not undergone a peer review process. The following aspects were extracted from each article: authors, year, country, the sample size of data and variables describing the type of clinical decision support models. The decision support models were classified in 2 ways: quantitative decision support models, and qualitative decision support models. RESULTS: The final number of studies included in the systematic literature review was 10. These clinical decision support models included 4/10 (40%) quantitative decision support models and 6/10 (60%) qualitative decision support models. The earliest article was published in 2007, and the most recent was from 2015. CONCLUSIONS: The clinical decision support models were targeted at a variety of different types of chronic wounds. The degree of accessibility of the inference engines varied. Quantitative models served as the engine and were invisible to the health care professionals, while qualitative models required interaction with the user. PMID- 30291079 TI - Effect of Diabetes Online Community Engagement on Health Indicators: Cross Sectional Study. AB - BACKGROUND: Successful diabetes management requires ongoing lifelong self-care and can require that individuals with diabetes become experts in translating care recommendations into real-life day-to-day diabetes self-care strategies. The diabetes online community comprises multiple websites that include social media sites, blogs, and discussion groups for people with diabetes to chat and exchange information. Online communities can provide disease-specific practical advice and emotional support, allow users to share experiences, and encourage self-advocacy and patient empowerment. However, there has been little research about whether diabetes online community use is associated with better diabetes self-care or quality of life. OBJECTIVE: The aim of this study was to survey adults with diabetes who participated in the diabetes online community to better understand and describe who is using the diabetes online community, how they are using it, and whether the use of the diabetes online community was associated with health indicators. METHODS: We recruited adults diagnosed with diabetes who used at least one of 4 different diabetes-related online communities to complete an online survey. Participants' demographics, reported glycated hemoglobin (HbA1c), health-related quality of life (SF-12v2), level of diabetes self-care (Self-Care Inventory-Revised), and diabetes online community use (level of intensity and engagement) were collected. We examined the relationships between demographics, diabetes online community use, and health indicators (health-related quality of life, self-care, and HbA1c levels). We used binary logistic regression to determine the extent to which diabetes online community use predicted an HbA1c <7% or >=7% after controlling statistically for other variables in the model. RESULTS: A total of 183 adults participated in this study. Participants were mostly female (71.6%, 131/183), white (95.1%, 174/183), US citizens (82.5%, 151/183), had type 1 diabetes (69.7%, 129/183), with a mean age of 44.7 years (SD 14) and diabetes duration of 18.2 years (SD 14.6). Participants had higher diabetes self-care (P<.001, mean 72.4, SD 12.1) and better health-related quality of life (physical component summary P<.001, mean 64.8, SD 19; mental component summary P<.001, mean 66.6, SD 21.6) when compared with norms for diabetes. Diabetes online community engagement was a strong predictor of A1c, reducing the odds of having an A1c >=7% by 33.8% for every point increase in diabetes online community engagement (0-5). Our data also indicated that study participants are oftentimes (67.2%, 123/183) not informing their healthcare providers about their diabetes online community use even though most (91.2%, 161/181) are seeing their healthcare provider on a regular basis. CONCLUSIONS: Our results suggest that individuals highly engaged with diabetes online community are more likely to have better glycemic levels compared with those with lower engagement. Furthermore, diabetes online community users have high health-related quality of life and diabetes self-care levels. Supplementing usual healthcare activities with diabetes online community use may encourage knowledge and support among a population that needs to optimize its diabetes self-care. Further studies are needed to determine how diabetes online community engagement may affect health outcomes. PMID- 30291080 TI - The Case for Jointly Targeting Diabetes and Depression Among Vulnerable Patients Using Digital Technology. AB - It is well publicized that mobile and digital technologies hold great promise to improve health outcomes among patients with chronic illnesses such as diabetes. However, there is growing concern that digital health investments (both from federal research dollars and private venture investments) have not yet resulted in tangible health improvements. We see three major reasons for this limited real world impact on health outcomes: (1) lack of solutions relevant for patients with multiple comorbidities or conditions, (2) lack of diverse patient populations involved in the design and early testing of products, and (3) inability to leverage existing clinical workflows to improve both patient enrollment and engagement in technology use. We discuss each of these in depth, followed by new research directions to increase effectiveness in this field. PMID- 30291081 TI - Outcomes of a Digitally Delivered Low-Carbohydrate Type 2 Diabetes Self Management Program: 1-Year Results of a Single-Arm Longitudinal Study. AB - BACKGROUND: Type 2 diabetes mellitus has serious health consequences, including blindness, amputation, stroke, and dementia, and its annual global costs are more than US $800 billion. Although typically considered a progressive, nonreversible disease, some researchers and clinicians now argue that type 2 diabetes may be effectively treated with a carbohydrate-reduced diet. OBJECTIVE: Our objective was to evaluate the 1-year outcomes of the digitally delivered Low-Carb Program, a nutritionally focused, 10-session educational intervention for glycemic control and weight loss for adults with type 2 diabetes. The program reinforces carbohydrate restriction using behavioral techniques including goal setting, peer support, and behavioral self-monitoring. METHODS: The study used a quasi experimental research design comprised of an open-label, single-arm, pre-post intervention using a sample of convenience. From adults with type 2 diabetes who had joined the program and had a complete baseline dataset, we randomly selected participants to be followed for 1 year (N=1000; mean age 56.1, SD 15.7 years; 59.30% (593/1000) women; mean glycated hemoglobin A1c (HbA1c) 7.8%, SD 2.1%; mean body weight 89.6 kg, SD 23.1 kg; taking mean 1.2, SD 1.01 diabetes medications). RESULTS: Of the 1000 study participants, 708 (70.80%) individuals reported outcomes at 12 months, 672 (67.20%) completed at least 40% of the lessons, and 528 (52.80%) completed all lessons of the program. Of the 743 participants with a starting HbA1c at or above the type 2 diabetes threshold of 6.5%, 195 (26.2%) reduced their HbA1c to below the threshold while taking no glucose-lowering medications or just metformin. Of the participants who were taking at least one hypoglycemic medication at baseline, 40.4% (289/714) reduced one or more of these medications. Almost half (46.40%, 464/1000) of all participants lost at least 5% of their body weight. Overall, glycemic control and weight loss improved, especially for participants who completed all 10 modules of the program. For example, participants with elevated baseline HbA1c (>=7.5%) who engaged with all 10 weekly modules reduced their HbA1c from 9.2% to 7.1% (P<.001) and lost an average of 6.9% of their body weight (P<.001). CONCLUSIONS: Especially for participants who fully engage, an online program that teaches a carbohydrate reduced diet to adults with type 2 diabetes can be effective for glycemic control, weight loss, and reducing hypoglycemic medications. PMID- 30291082 TI - Web-Based Interventions for Depression in Individuals with Diabetes: Review and Discussion. AB - BACKGROUND: Depression is twice as common in people with diabetes, and this comorbidity worsens the course of both pathologies. In clinical practice guidelines, screening and treatment of depression in patients with diabetes are highly recommended. However, depression is still both underrecognized and undertreated. To find ways to enhance their reach, psychological treatments have taken advantage of benefits of internet and technological devices as delivery formats, providing interventions that require considerably less (or even no) interaction time with therapists. Web-based treatments hold promise for effective interventions at low cost with positive results. OBJECTIVE: The objectives of this review were to describe Web-based interventions for depression in individuals with diabetes and to discuss these studies' procedures and findings in light of evidence from a wider range of interventions for depression and diabetes. METHODS: A comprehensive literature search was conducted in PsycINFO and MEDLINE electronic databases. Studies were included when they met the following selection criteria: the study was available in a peer-reviewed journal mainly publishing studies written in either English or Spanish; the studied sample comprised individuals with diabetes; the intervention targeted depression symptomatology; the intervention was accessible via the internet; and the intervention was accessible via the internet with little or no clinician support. RESULTS: Overall, 5 research studies were identified in the review. All studies were randomized controlled trials, and most used a wait list as a control; 4 studies reported treatment dropout, rates of which varied from 13% to 42%. Studies supported the notion that the Web-based format is a suitable psychology service delivery option for diabetic individuals with depression (effect size range for completers 0.7-0.89). Interventions varied in their characteristics but most were clinical-assisted, had a cognitive behavioral therapy approach, used diabetes-specific topics, had a weekly modular display, used homework assignments, and had some adherence management strategy. These characteristics are consistent with the intervention features associated with positive results in the literature. CONCLUSIONS: The analyzed studies' findings and procedures are discussed in light of evidence drawn from a wider range of reviews on Web-based interventions for depression and diabetes. Consistent with previous research on depression treatment, Web-based interventions for depression among individuals with diabetes have shown positive results. Future research should contribute new evidence as to why these interventions are effective, for whom, and which particular aspects can increase patients' adherence. PMID- 30291083 TI - Information and Communication Technology-Powered Diabetes Self-Management Systems in China: A Study Evaluating the Features and Requirements of Apps and Patents. AB - BACKGROUND: For patients with diabetes, the self-monitoring of blood glucose (SMBG) is a recommended way of controlling the blood glucose level. By leveraging the modern information and communication technology (ICT) and the corresponding infrastructure, engineers nowadays are able to merge the SMBG activities into daily life and to dramatically reduce patient's burden. Such type of ICT-powered SMBG had already been marketed in the United States and the European Union for a decade, but was introduced into the Chinese market only in recent years. Although there is no doubt about the general need for such type of SMBG in the Chinese market, how it could be adapted to the local technical and operational environment is still an open question. OBJECTIVE: Our overall goal is to understand the local requirements and the current status of deploying ICT-powered SMBG to the Chinese market. In particular, we aim to analyze existing domestic SMBG mobile apps and relevant domestic patents to identify their various aspects, including the common functionalities, innovative feature, defects, conformance to standards, prospects, etc. In the long run, we hope the outcome of this study could help the decision making on how to properly adapt ICT-powered SMBG to the Chinese market. METHODS: We identified 289 apps. After exclusion of irrelevant apps, 78 apps remained. These were downloaded and analyzed. A total of 8070 patents related to glucose were identified from patent database. Irrelevant materials and duplicates were excluded, following which 39 patents were parsed to extract the important features. These apps and patents were further compared with the corresponding requirements derived from relevant clinical guidelines and data standards. RESULTS: The most common features of studied apps were blood health data recording, notification, and decision supporting. The most common features of studied patents included mobile terminal, server, and decision supporting. The main difference between patents and apps is that the patents had 2 specific features, namely, interface to the hospital information system and recording personal information, which were not mentioned in the app. The other major finding is that, in general, in terms of the components of the features, although the features identified in both apps and patents conform to the requirements of the relevant clinical guidelines and data standards, upon looking into the details, gaps exist between the features of the identified apps and patents and the relevant clinical guidelines and data standards. In addition, the social media feature that the apps and patents have is not included in the standard requirements list. CONCLUSIONS: The development of Chinese SMBG mobile apps and relevant patents is still in the primitive stage. Although the functionalities of most apps and patents can meet the basic requirements of SMBG, gaps have been identified when comparing the functionalities provided by apps and patents with the requirements necessitated by the standards. One of the most important gaps is that only a small portion of the studied apps provides the automatic data transmission and exchange feature, which may hamper the overall performance. The clinical guidelines can thus be further developed to leverage new features provided by ICT-powered SMBG apps (eg, the social media feature, which may help to improve the social intervention of patients with diabetes). PMID- 30291084 TI - Machine or Human? Evaluating the Quality of a Language Translation Mobile App for Diabetes Education Material. AB - BACKGROUND: Diabetes is a major health crisis for Hispanics and Asian Americans. Moreover, Spanish and Chinese speakers are more likely to have limited English proficiency in the United States. One potential tool for facilitating language communication between diabetes patients and health care providers is technology, specifically mobile phones. OBJECTIVE: Previous studies have assessed machine translation quality using only writing inputs. To bridge such a research gap, we conducted a pilot study to evaluate the quality of a mobile language translation app (iTranslate) with a voice recognition feature for translating diabetes patient education material. METHODS: The pamphlet, "You are the heart of your family...take care of it," is a health education sheet for diabetes patients that outlines three recommended questions for patients to ask their clinicians. Two professional translators translated the original English sentences into Spanish and Chinese. We recruited six certified medical translators (three Spanish and three Chinese) to conduct blinded evaluations of the following versions: (1) sentences interpreted by iTranslate, and (2) sentences interpreted by the professional human translators. Evaluators rated the sentences (ranging from 1-5) on four scales: Fluency, Adequacy, Meaning, and Severity. We performed descriptive analyses to examine the differences between these two versions. RESULTS: Cronbach alpha values exhibited high degrees of agreement on the rating outcomes of both evaluator groups: .920 for the Spanish raters and .971 for the Chinese raters. The readability scores generated using MS Word's Flesch-Kincaid Grade Level for these sentences were 0.0, 1.0, and 7.1. We found iTranslate generally provided translation accuracy comparable to human translators on simple sentences. However, iTranslate made more errors when translating difficult sentences. CONCLUSIONS: Although the evidence from our study supports iTranslate's potential for supplementing professional human translators, further evidence is needed. For this reason, mobile language translation apps should be used with caution. PMID- 30291085 TI - Use of a Mobile App to Facilitate Blood Glucose Monitoring in Adolescents With Type 1 Diabetes: Single-Subject Nonrandomized Clinical Trial. AB - BACKGROUND: Cloud-based glucose monitoring programs allow users with diabetes to wirelessly synchronize their glucometers to their mobile phones. They also provide visualization and remote access of their data through its mobile app. There have been very few studies evaluating their effectiveness in managing diabetes among adolescents with type 1 diabetes (T1D). OBJECTIVE: The purpose of this study was to assess the feasibility of using a mobile app to improve daily average blood glucose (BG) levels and increase BG monitoring frequency. METHODS: We used an ABA single-subject prospective study design. We recruited five participants aged 13 to 17 years with uncontrolled T1D, glycated hemoglobin A1c 9.0%-10.7%, self-monitoring behavior of <=5 checks/day, and on multiple daily insulin injections. The study consisted of 4-week intervals of three phases: (1) phase A: usual glucose monitoring log (fax); (2) phase B: mobile app; and (3) phase A': second phase A. A certified diabetes educator and endocrinologist reviewed logs and provided recommendations weekly. Data were analyzed using a quasi-Poisson model to adjust for overdispersion among individual participants, and a generalized estimating equation model for overall intervention effect in aggregate. RESULTS: For mean daily BG (mg/dL) levels, participant 1 had decreased values on the mobile app (298 to 281, P=.03) and maintained in phase A'. Participant 4 had an increase in mean daily BG in phase A' (175 to 185, P=.01), whereas participant 5 had a decrease in mean daily BG in phase A' (314 to 211, P=.04). For daily monitoring (checks/day), participant 3 increased in phase B (4.6 to 8.3, P=.01) and maintained in phase A'. Participant 5 also had increased daily monitoring at each phase (2.1 to 2.4, P=.01; 2.4 to 3.4, P=.02). For the five participants combined, the overall mean BG and BG checks per day in phase A were mean 254.8 (SD 99.2) and mean 3.6 (SD 2.0), respectively, mean 223.1 (SD 95.7) and mean 4.5 (SD 3.0) in phase B, and mean 197.5 (SD 81.3) and mean 3.7 (SD 2.1) in phase A'. Compared to phase A, mean glucose levels declined during phase B and remained lower during phase A' (P=.002). There was no overall change in BG checks by phase (P=.25). However, mean BG levels negatively correlated with daily BG checks (r=-.47, P<.001). Although all participants had positive opinions about the app, its utilization was highly variable. CONCLUSIONS: We demonstrated modest feasibility of adolescents with uncontrolled T1D utilizing a glucose monitoring mobile app. Further study is needed to better determine its effects on BG level and monitoring frequency. Psychosocial factors and motivational barriers likely influence adoption and continuous use of technology for diabetes management. PMID- 30291086 TI - Exploring the Use of Personal Technology in Type 2 Diabetes Management Among Ethnic Minority Patients: Cross-Sectional Analysis of Survey Data from the Lifestyle Intervention for the Treatment of Diabetes Study (LIFT Diabetes). AB - BACKGROUND: Minority populations have higher morbidity from chronic diseases and typically experience worse health outcomes. Internet technology may afford a low cost method of ongoing chronic disease management to promote improved health outcomes among minority populations. OBJECTIVE: The objective of our study was to assess the feasibility of capitalizing on the pervasive use of technology as a secondary means of delivering diabetic counseling though an investigation of correlates to technology use within the context of an ongoing diabetes intervention study. METHODS: The Lifestyle Intervention for the Treatment of Diabetes study (LIFT Diabetes) randomly assigned 260 overweight and obese adults with type 2 diabetes mellitus to 2 intervention arms. At baseline, we administered a survey evaluating access to and use of various technologies and analyzed the responses using descriptive statistics and logistic regression. RESULTS: The sample population had a mean age of 56 (SD 11) years; 67.3% (175/260) were female and 54.6% (n=142) self-identified as being from ethnic minority groups (n=125, 88.0% black; n=6, 4.3% Hispanic; and n=11, 7.7% other). Minority participants had higher baseline mean body mass index (P=.002) and hemoglobin A1c levels (P=.003). Minority participants were less likely to have a home computer (106/142, 74.7% vs 110/118, 93.2%; P<.001) and less likely to have email access at home (P=.03). Ownership of a home computer was correlated to higher income (P<.001), higher educational attainment (P<.001), full-time employment (P=.01), and ownership of a smartphone (P=.001). Willingness to complete questionnaires online was correlated to higher income (P=.001), higher education (P<.001), full-time employment (P=.01), and home access to a computer, internet, and smartphone (P<=.05). Racial disparities in having a home computer persisted after controlling for demographic variables and owning a smartphone (adjusted OR 0.26, 95% CI 0.10-0.67; P=.01). Willingness to complete questionnaires online was driven by ownership of a home computer (adjusted OR 3.87, 95% CI 1.14-13.2; P=.03). CONCLUSIONS: Adults who self-identified as being part of a minority group were more likely to report limited access to technology than were white adults. As ownership of a home computer is central to a willingness to use online tools, racial disparities in access may limit the potential of Web-based interventions to reach this population. TRIAL REGISTRATION: ClinicalTrials.gov NCT01806727; https://clinicaltrials.gov/ct2/show/NCT01806727 (Archived by WebCite at http://www.webcitation.org/6xOq2b7Tv). PMID- 30291087 TI - A Fully Automated Conversational Artificial Intelligence for Weight Loss: Longitudinal Observational Study Among Overweight and Obese Adults. AB - BACKGROUND: Type 2 diabetes is the most expensive chronic disease in the United States. Two-thirds of US adults have prediabetes or are overweight and at risk for type 2 diabetes. Intensive in-person behavioral counseling can help patients lose weight and make healthy behavior changes to improve their health outcomes. However, with the shortage of health care providers and associated costs, such programs do not adequately service all patients who could benefit. The health care system needs effective and cost-effective interventions that can lead to positive health outcomes as scale. This study investigated the ability of conversational artificial intelligence (AI), in the form of a standalone, fully automated text-based mobile coaching service, to promote weight loss and other health behaviors related to diabetes prevention. This study also measured user acceptability of AI coaches as alternatives to live health care professionals. OBJECTIVE: The objective of this study was to evaluate weight loss, changes in meal quality, and app acceptability among users of the Lark Weight Loss Health Coach AI (HCAI), with the overarching goal of increasing access to compassionate health care via mobile health. Lessons learned in this study can be applied when planning future clinical trials to evaluate HCAI and when designing AI to promote weight loss, healthy behavior change, and prevention and self-management of chronic diseases. METHODS: This was a longitudinal observational study among overweight and obese (body mass index >=25) participants who used HCAI, which encourages weight loss and healthy diet choices through elements of cognitive behavioral therapy. Weight loss, meal quality, physical activity, and sleep data were collected through user input and, for sleep and physical activity, partly through automatic detection by the user's mobile phone. User engagement was assessed by duration and amount of app use. A 4-question in-app user trust survey assessed app usability and acceptability. RESULTS: Data were analyzed for participants (N=70) who met engagement standards set forth by the Centers for Disease Control and Prevention criteria for Diabetes Prevention Program, a clinically proven weight loss program focused on preventing diabetes. Weight loss (standard error of the mean) was 2.38% (0.69%) of baseline weight. The average duration of app use was 15 (SD 1.0) weeks, and users averaged 103 sessions each. Predictors of weight loss included duration of AI use, number of counseling sessions, and number of meals logged. Percentage of healthy meals increased by 31%. The in-app user trust survey had a 100% response rate and positive results, with a satisfaction score of 87 out of 100 and net promoter score of 47. CONCLUSIONS: This study showed that use of an AI health coach is associated with weight loss comparable to in-person lifestyle interventions. It can also encourage behavior changes and have high user acceptability. Research into AI and its application in telemedicine should be pursued, with clinical trials investigating effects on weight, health behaviors, and user engagement and acceptability. PMID- 30291088 TI - Functionality, Implementation, Impact, and the Role of Health Literacy in Mobile Phone Apps for Gestational Diabetes: Scoping Review. AB - BACKGROUND: The increasing ownership of mobile phones and advances in hardware and software position these devices as cost-effective personalized tools for health promotion and management among women with gestational diabetes mellitus (GDM). Numerous mobile phone apps are available online; however, to our knowledge, no review has documented how these apps are developed and evaluated in relation to GDM. OBJECTIVE: The objective of our review was to answer the following 2 research questions: (1) What is known from the existing literature about the availability, functionality, and effectiveness of mobile phone apps on GDM prevention and management? (2) What is the role of health literacy in these apps? METHODS: We searched 7 relevant electronic databases for original research documents using terms related to mobile phone apps, GDM, and health literacy. We thematically categorized selected articles using a framework adapted from Arksey and O'Malley. RESULTS: We included 12 articles related to 7 apps or systems in the final analysis. We classified articles around 2 themes: (1) description of the development, feasibility, or usability of the apps or systems, and (2) trial protocols. The degree of personalization varied among the apps for GDM, and decision support systems can be used to generate time-efficient personalized feedback for both patients and health care providers. Health literacy was considered during the development or measured as an outcome by some apps. CONCLUSIONS: There is a limited body of research on mobile phone apps in relation to GDM prevention and management. Mobile phone apps can provide time- and cost efficient personalized interventions for GDM. Several randomized controlled trials have been launched recently to evaluate the effectiveness of the apps. Consideration of health literacy should be improved when developing features of the apps. PMID- 30291089 TI - Views of Patients on Using mHealth to Monitor and Prevent Diabetic Foot Ulcers: Qualitative Study. AB - BACKGROUND: People with diabetes are at risk for diabetic foot ulcers (DFUs), which can lead to limb loss and a significant decrease in quality of life. Evidence suggests that mHealth can be an effective tool in diabetes self management. mHealth presents an opportunity for the prevention and monitoring of DFUs. However, there is a paucity of research that explores its effectiveness in the DFU patient population, as well as the views and attitudes of these patients toward technology and mHealth. OBJECTIVE: This study aimed to explore the views, attitudes, and experiences of a diabetic patient population with or at risk of DFUs regarding technology, mHealth, and the diabetic foot. METHODS: We used a qualitative research approach using in-depth interviews with 8 patients with DFUs. Questions were structured around experience with technology, current health practices related to diabetic foot care, and thoughts on using an mHealth device that prevents and monitors DFUs. We transcribed and thematically analyzed all interviews. RESULTS: All patients had positive responses for an mHealth intervention aimed at preventing and monitoring DFUs. We found 4 themes in the data: diversity in use of technology, feet-checking habits, 2-way communication with health care professionals (HCPs), and functionality. There were varying levels of familiarity with and dependence on technology within this patient population. These relationships correlated with distinct generations found in North America, including baby boomers and Generation X. Furthermore, we found that most patients performed daily feet checks to monitor any changes in health. However, some did not perform feet checks prior to the development of a DFU. Patients expressed interest in 2-way communication with HCPs that would allow for easier appointment scheduling, sharing of medical data, decreased number of visits, and use of alerts for when medical attention is required. Patients also identified conditions of functionality for the mHealth intervention. These included consideration of debilitating complications because of diabetes, such as retinopathy and decreased mobility; ease of use of the intervention; and implementation of virtual communities to support continued use of the intervention. CONCLUSIONS: Our patient population expressed an interest in mHealth for preventing and monitoring DFUs, although some participants were not frequent users of technology. mHealth continues to show potential in improving patient outcomes, and this study provides a foundation for designing interventions specific to a DFU population. Further research is needed to confirm these findings. PMID- 30291090 TI - Addressing Disparities in Diabetes Management Through Novel Approaches to Encourage Technology Adoption and Use. AB - Type 2 diabetes (T2D) is one of the nation's leading drivers of disability and health care utilization, with elevated prevalence among individuals with lower education, income, and racial/ethnic minorities. Health information technology (HIT) holds vast potential for helping patients, providers, and payers to address T2D and the skyrocketing rates of chronic illness and associated health care costs. Patient portals to electronic health records (EHRs) serve as a gateway to consumer use of HIT. We found that disparities in portal use portend growing T2D disparities. Little progress has been made in addressing identified barriers to technology adoption, especially among populations with elevated risk of T2D. Patients often lack digital literacy skills and continuous connectivity and fear loss of the relationship with providers. Providers may experience structural disincentives to promoting patient use of HIT and apply hidden biases that inhibit portal use. Health care systems often provide inadequate training to patients and providers in use of HIT, and lack resources devoted to obtaining and optimizing use of data generated by HIT. Lastly, technology-related barriers include inadequate consideration of user perspectives, lack of evidence for patient-focused apps, and lack of features to enable providers and health care systems to readily obtain aggregate data to improve care and facilitate research. After discussing these barriers in detail, we propose possible solutions and areas where further research is needed to ensure that individuals and health care systems obtain the full benefit of the nation's planned $38 billion HIT investment. A digital inclusion framework sheds new light on barriers posed for patients with social health inequalities. We have determined that partnerships with community organizations focused on digital inclusion could help health systems explore and study new approaches, such as universal screening and referral of patients for digital skills, health literacy, and Internet connectivity. PMID- 30291091 TI - A Website to Promote Physical Activity in People With Type 2 Diabetes Living in Remote or Rural Locations: Feasibility Pilot Randomized Controlled Trial. AB - BACKGROUND: Research supports the use of Web-based interventions to promote physical activity in diabetes management. However, previous interventions have found poor levels of engagement or have not included health professionals and people with diabetes in the design of the tool. OBJECTIVE: To develop and explore the feasibility and indicative effect of a Web-based physical activity promotion intervention in people diagnosed with type 2 diabetes living in remote or rural locations. METHODS: A qualitative approach using focus groups that included patients with diabetes and health professionals were run to identify key concepts, ideas, and features, which resulted in the design of a physical activity website. This site was tested using a quantitative approach with a qualitative 6-month pilot study that adopted a three-armed approach. Participants were randomized into three groups: a control group who received written diabetes specific physical activity advice; an information Web group, a Web-based group who received the information online; and an intervention Web group, an interactive Web-based group who received online information plus interactive features, such as an activity log, personalized advice, and goal setting. RESULTS: A website was designed based on patient and health professional ideas for effective physical activity promotion. This website was tested with 31 participants, 61% (19/31) male, who were randomized into the groups. Website log ins decreased over time: 4.5 times in month 1, falling to 3 times in month 6. Both the information Web group-mean 134.6 (SD 123.9) to mean 154.9 (SD 144.2) min and the control group-mean 118.9 (SD 103.8) to mean 126.1 (SD 93.4) min, d=0.07 increased time spent in moderate-to-vigorous physical activity, but this decreased in the intervention Web group-mean 131.9 (SD 126.2) to mean 116.8 (SD 107.4) min. CONCLUSIONS: Access to online diabetes-specific physical information was effective in promoting physical activity in people with type 2 diabetes; access to interactive features was not associated with increases in activity.

PMID- 30291092 TI - Diabetes App-Related Text Messages From Health Care Professionals in Conjunction With a New Wireless Glucose Meter With a Color Range Indicator Improves Glycemic Control in Patients With Type 1 and Type 2 Diabetes: Randomized Controlled Trial. AB - BACKGROUND: Mobile diabetes apps enable health care professionals (HCPs) to monitor patient progress, offer remote consultations, and allow more effective and informed treatment decisions between patients and HCPs. The OneTouch Reveal app aggregates data from a blood glucose meter and provides analytics to help patients and HCPs visualize glycemic trends and patterns, enabling more informed treatment and lifestyle decisions. The app also allows patients and HCPs to keep connected by exchanging text messages (short message service [SMS]) or progress reports via email. OBJECTIVE: The primary objective of our study was to assess changes in glycemic control and overall experiences of patients and HCPs using the app in conjunction with the wireless OneTouch Verio Flex blood glucose meter. METHODS: We randomly assigned 137 adults with type 1 (T1DM) or type 2 diabetes mellitus (T2DM) and a glycated hemoglobin (HbA1c) level of >=7.5% and <=11.0% to use the glucose meter alone or glucose meter plus the app for 24 weeks. The meter + app group were scheduled to receive diabetes-related text messages from their HCP every 2 weeks (total of 12 texts). Clinical measures and self-reported outcomes were assessed during face-to-face clinic visits between the participant and a diabetes nurse at baseline, week 12, and week 24. RESULTS: In 128 completed participants, HbA1c decreased after 12 and 24 weeks in both the meter-only (n=66) (0.56% and 0.55%, respectively) and meter + app groups (n=62) (0.78% and 0.67%, respectively) compared with baseline (each P<.001). The difference in HbA1c reduction between the 2 groups was not statistically significant at 12 or 24 weeks (P=.12 and P=.45, respectively). However, the decrease in HbA1c was greater in T2DM participants using the meter + app after 12 weeks (1.04%) than in T2DM participants using the meter alone (0.58%; P=.09). In addition, decrease in HbA1c in participants using the meter + app who received at least 10 diabetes-related text messages (1.05%) was significantly greater than in meter-only participants (P<.01). CONCLUSIONS: Use of the OneTouch Verio Flex glucose meter alone or in combination with the OneTouch Reveal diabetes app was associated with significant improvements in glycemic control after 12 and 24 weeks. Improvements using the app were greatest in participants with T2DM and those participants who received the highest number of HCP text messages. This study suggests that real-time availability of patient data and the ability to send personalized diabetes related text messages can assist HCPs to improve glycemic control in patients between scheduled visits.

PMID- 30291093 TI - Digital Health for Medication Adherence in Adult Diabetes or Hypertension: An Integrative Review. AB - BACKGROUND: Optimal management of chronic diseases, such as type 2 diabetes and hypertension, often include prescription medications. Medication adherence (MA) is one component of self-management. Optimization through digital health-eHealth and mHealth-could enhance patient awareness and/or communication between the patient and provider. OBJECTIVE: Medication adherence is a major issue that affects 50%-60% of chronically ill adults. Digital health refers to eHealth and mHealth, collectively, and as these technologies become more accessible, remote health delivery is increasingly available as an adjunct to improve medication adherence; communicate with patients and providers; and provide education to patients, families, and communities. The objective of this integrative review was to examine the types of digital health technologies that targeted medication adherence in the adult population with diabetes or hypertension. METHODS: An integrative review was conducted using databases within EBSCOhost, PubMed, and Scopus. Eligible studies available as of September 2016 had to be written in English, had to contain digital health interventions to improve medication adherence to prescription medications in adults 18 years or older, and had to focus on diabetes or hypertension. RESULTS: Of the 337 located studies, 13 (3.9%) used a digital health intervention for medication adherence to prescribed medications for diabetes or hypertension and were assessed according to the Chronic Care Model. CONCLUSIONS: The 13 studies included in this review found no conclusive evidence of improved medication adherence using digital health interventions such as interactive voice response (IVR), short message service (SMS) text messaging, telemonitoring, and interactive software technology. Among the 13 studies were digital health interventions that foster medication adherence via one-way communication to the patient or two-way communication between the patient and health care provider for adjunct medication adherence strategies. More research is needed to determine which digital health interventions are most beneficial for individuals with diabetes or hypertension.

AB - BACKGROUND: Given disparities in diabetes prevalence, receipt of diabetes education, diabetes knowledge, and self-management behaviors among Latinos, there is a need to provide education and ongoing support to this population. Phone based interventions have the potential to reach and engage both patients and their family members and friends. OBJECTIVE: The aim of this study was to investigate the feasibility, perceived usefulness, and potential effectiveness of a short text or voice message (STVM) intervention to activate (1) physical activity (PA) behavior change among urban, low-income Latino adults with type 2 diabetes and (2) supportive behaviors by their family members and friends. METHODS: A 12-week pilot study randomized 42 participants recruited in person from a safety-net ambulatory care clinic in Los Angeles into one of the 3 study arms: control, phone messaging (PM), and phone messaging plus social support from family members and friends (PM+FF). All participants were prompted to set PA goals and to self-monitor PA behavior using pedometers and walking logs. PM and PM+FF participants received STVMs with reminders to review goals and self monitor, PA behavior change education, and feedback on performance. Participants in the PM+FF arm also had their family members and friends receiving STVMs with suggestions for how they could support the participant's PA behavior change efforts. Participants completed semistructured assessments in person at baseline, 6 weeks, and 12 weeks. Outcomes were PA (steps/day) and perceived social support from family members and friends. RESULTS: Among PM and PM+FF participants, those who opted to receive text messages (short message service, SMS) responded to 62.7% (128/204) of SMS text messages requiring a response while those who opted to receive voice messages responded 30% (12/40) of the time. Participants perceived guidance in self-regulation as useful, particularly self-monitoring, goal setting, self-instruction, feedback, and social support. All participants increased PA at 6 weeks, but only the PM and PM+FF arms increased PA at 12 weeks. All study arms experienced an increase in perceived social support from family members and friends at 6 weeks, but only those in the PM+FF arm had an increase in the perception of social support at 12 weeks. CONCLUSION: Designing an STVM intervention based on self-regulation techniques is feasible and perceived as useful by participants. The STVM intervention has the potential to improve PA in terms of daily steps and perceived social support from family members and friends.

PMID- 30291095 TI - Situation of Diabetes and Related Factors Among Qatari Adults: Findings From a Community-Based Survey. AB - BACKGROUND: Diabetes mellitus (DM) is a prominent public health problem in Qatar with one of the highest prevalence in the Gulf Cooperation Council region. Obesity continues to be a challenging public health problem in Qatar along with other social determinants contributing to the high DM prevalence. OBJECTIVE: This paper examines the data from Qatar National STEPS survey (2012) to determine diabetes prevalence among Qatari adults and identify the effect of both generalized and central obesity on it. The article also describes the contribution of selected social and demographic factors on diabetes prevalence in Qatar. METHODS: Secondary data analysis of 1471 Qatari adults (18-64 years) from STEP 3 component of the 2012 STEPS Survey was executed. Multivariate binary logistic regression analysis was carried out to assess the role of social and biomedical factors in the prevalence of DM. RESULTS: Among participants, 18.97% (279/1471) of the study population had DM. Both generalized (OR 1.8, P=.005) and central obesity (OR 1.9, P<.001) were significantly associated with DM when adjusted for various respondent characteristics. Older age (P<.001), marital status of ever married (P<.001), and lower educational status (P=.01) were associated with DM. Hypertension (OR 1.5, P=.003 total cholesterol level >=190 mg/dL (OR 2.2, P<.001) and triglyceride level >=150 mg/dL (OR 3.6, P<.001) were significantly associated with DM among the study participants. Although family history of DM was significantly associated with development of DM (OR 1.7, P=.01), parental consanguinity was not associated with DM (OR 0.96, P=.80). CONCLUSIONS: The DM prevalence in Qatar seems to be highly associated with obesity; however, various additional population characteristics and comorbidity factors should also require attention and should be incorporated while developing intervention strategies. PMID- 30291096 TI - iOS Appstore-Based Phone Apps for Diabetes Management: Potential for Use in Medication Adherence. AB - BACKGROUND: Currently, various phone apps have been developed to assist patients. Many of these apps are developed to assist patients in the self-management of chronic diseases such as diabetes. It is essential to analyze these various apps to understand the key features that would potentially be instrumental in helping patients successfully achieve goals in disease self-management. OBJECTIVE: The objective of this study was to conduct a review of all the available diabetes related apps in the iOS App Store to evaluate which diabetic app is more interactive and offers a wide variety of operations such as monitoring glucose, water, carbohydrate intake, weight, body mass index (BMI), medication, blood pressure (BP) levels, reminders or push notifications, food database, charts, exercise management, email, sync between devices, syncing data directly to the prescribers, and other miscellaneous functions such as (Twitter integration, password protection, retina display, barcode scanner, apple watch functionality, and cloud syncing). METHODS: Data was gathered using the iOS App Store on an iPad. The search term "diabetes" resulted in 1209 results. Many of the results obtained were remotely related to diabetes and focused mainly on diet, exercise, emergency services, refill reminders, providing general diabetes information, and other nontherapeutic options. We reviewed each app description and only included apps that were meant for tracking blood glucose levels. All data were obtained in one sitting by one person on the same device, as we found that carrying out the search at different times or on different devices (iPhones) resulted in varying results. Apps that did not have a feature for tracking glucose levels were excluded from the study. RESULTS: The search resulted in 1209 results; 85 apps were retained based on the inclusion criteria mentioned above. All the apps were reviewed for average customer ratings, number of reviews, price, and functions. Of all the apps surveyed, 18 apps with the highest number of user ratings were used for in-depth analysis. Of these 18 apps, 50% (9/18) also had a medication adherence function. Our analysis revealed that the Diabetes logbook used by the mySugr app was one of the best; it differentiated itself by introducing fun as a method of increasing adherence. CONCLUSIONS: A large variation was seen in patient ratings of app features. Many patient reviewers desired simplicity of app functions. Glucose level tracking and email features potentially helped patients and health care providers manage the disease more efficiently. However, none of the apps could sync data directly to the prescribers. Additional features such as graph customization, availability of data backup, and recording previous entries were also requested by many users. Thus, the use of apps in disease management and patient and health-care provider involvement in future app refinement and development should be encouraged. PMID- 30291097 TI - Design and Development of a Context-Aware Knowledge-Based Module for Identifying Relevant Information and Information Gaps in Patients With Type 1 Diabetes Self Collected Health Data. AB - BACKGROUND: Patients with diabetes use an increasing number of self-management tools in their daily life. However, health institutions rarely use the data generated by these services mainly due to (1) the lack of data reliability, and (2) medical workers spending too much time extracting relevant information from the vast amount of data produced. This work is part of the FullFlow project, which focuses on self-collected health data sharing directly between patients' tools and EHRs. OBJECTIVE: The main objective is to design and implement a prototype for extracting relevant information and documenting information gaps from self-collected health data by patients with type 1 diabetes using a context aware approach. The module should permit (1) clinicians to assess the reliability of the data and to identify issues to discuss with their patients, and (2) patients to understand the implication their lifestyle has on their disease. METHODS: The identification of context and the design of the system relied on (1) 2 workshops in which the main author participated, 1 patient with type 1 diabetes, and 1 clinician, and (2) a co-design session involving 5 patients with type 1 diabetes and 4 clinicians including 2 endocrinologists and 2 diabetes nurses. The software implementation followed a hybrid agile and waterfall approach. The testing relied on load, and black and white box methods. RESULTS: We created a context-aware knowledge-based module able to (1) detect potential errors, and information gaps from the self-collected health data, (2) pinpoint relevant data and potential causes of noticeable medical events, and (3) recommend actions to follow to improve the reliability of the data issues and medical issues to be discussed with clinicians. The module uses a reasoning engine following a hypothesize-and-test strategy built on a knowledge base and using contextual information. The knowledge base contains hypotheses, rules, and plans we defined with the input of medical experts. We identified a large set of contextual information: emotional state (eg, preferences, mood) of patients and medical workers, their relationship, their metadata (eg, age, medical specialty), the time and location of usage of the system, patient-collected data (eg, blood glucose, basal-bolus insulin), patients' goals and medical standards (eg, insulin sensitivity factor, in range values). Demonstrating the usage of the system revealed that (1) participants perceived the system as useful and relevant for consultation, and (2) the system uses less than 30 milliseconds to treat new cases. CONCLUSIONS: Using a knowledge-based system to identify anomalies concerning the reliability of patients' self-collected health data to provide information on potential information gaps and to propose relevant medical subjects to discuss or actions to follow could ease the introduction of self collected health data into consultation. Combining this reasoning engine and the system of the FullFlow project could improve the diagnostic process in health care. PMID- 30291098 TI - Experiences of Using Web-Based and Mobile Technologies to Support Self-Management of Type 2 Diabetes: Qualitative Study. AB - BACKGROUND: The prevalence of type 2 diabetes is rising, placing increasing strain on health care services. Web-based and mobile technologies can be an important source of information and support for people with type 2 diabetes and may prove beneficial with respect to reducing complications due to mismanagement. To date, little research has been performed to gain an insight into people's perspectives of using such technologies in their daily management. OBJECTIVE: The purpose of this study was to understand the impact of using Web-based and mobile technologies to support the management of type 2 diabetes. METHODS: In-depth interviews were conducted with 15 people with type 2 diabetes to explore experiences of using Web-based and mobile technologies to manage their diabetes. Transcripts were analyzed using the framework method. RESULTS: Technology supported the users to maintain individualized and tailored goals when managing their health. A total of 7 themes were identified as important to participants when using technology to support self-management: (1) information, (2) understanding individual health and personal data, (3) reaching and sustaining goals, (4) minimizing disruption to daily life, (5) reassurance, (6) communicating with health care professionals, and (7) coordinated care. CONCLUSIONS: Patients need to be supported to manage their condition to improve well-being and prevent diabetes-related complications from arising. Technologies enabled the users to get an in-depth sense of how their body reacted to both lifestyle and medication factors-something that was much more difficult with the use of traditional standardized information alone. It is intended that the results of this study will inform a new questionnaire designed to assess self management in people using Web-based and mobile technology to manage their health. PMID- 30291099 TI - Clinically Excellent Use of the Electronic Health Record: Review. AB - BACKGROUND: The transition to the electronic health record (EHR) has brought forth a rapid cultural shift in the world of medicine, presenting both new challenges as well as opportunities for improving health care. As clinicians work to adapt to the changes imposed by the EHR, identification of best practices around the clinically excellent use of the EHR is needed. OBJECTIVE: Using the domains of clinical excellence previously defined by the Johns Hopkins Miller Coulson Academy of Clinical Excellence, this review aims to identify best practices around the clinically excellent use of the EHR. METHODS: The authors searched the PubMed database, using keywords related to clinical excellence domains and the EHR, to capture the English-language, peer-reviewed literature published between January 1, 2000, and August 2, 2016. One author independently reviewed each article and extracted relevant data. RESULTS: The search identified 606 titles, with the majority (393/606, 64.9%) in the domain of communication and interpersonal skills. Twenty-eight of the 606 (4.6%) titles were excluded from full-text review, primarily due to lack of availability of the full-text article. The remaining 578 full-text articles reviewed were related to clinical excellence generally (3/578, 0.5%) or the specific domains of communication and interpersonal skills (380/578, 65.7%), diagnostic acumen (31/578, 5.4%), skillful negotiation of the health care system (4/578, 0.7%), scholarly approach to clinical practice (41/578, 7.1%), professionalism and humanism (2/578, 0.4%), knowledge (97/578, 16.8%), and passion for clinical medicine (20/578, 3.5%). CONCLUSIONS: Results suggest that as familiarity and expertise are developed, clinicians are leveraging the EHR to provide clinically excellent care. Best practices identified included deliberate physical configuration of the clinical space to involve sharing the screen with patients and limiting EHR use during difficult and emotional topics. Promising horizons for the EHR include the ability to augment participation in pragmatic trials, identify adverse drug effects, correlate genomic data to clinical outcomes, and follow data-driven guidelines. Clinician and patient satisfaction with the EHR has generally improved with time, and hopefully continued clinician, and patient input will lead to a system that satisfies all. PMID- 30291100 TI - Web-Based Weight Loss Intervention for Men With Type 2 Diabetes: Pilot Randomized Controlled Trial. AB - BACKGROUND: Rising obesity levels remain a major public health concern due to the clear link with several comorbidities such as diabetes. Diabetes now affects 6% of the UK population. Modest weight loss of 5% to 10% has been shown to be associated with significant reductions in blood sugar, lipid, and blood pressure levels. Men have been shown to be attracted to programs that do not require extensive face-to-face time commitments, illustrating the potential audience available for health behavior change via the Web. OBJECTIVE: The objective of our study was to evaluate the feasibility and acceptability of a Web-based weight loss intervention in men with type 2 diabetes. METHODS: We conducted a pilot, parallel 2-arm, individually randomized controlled trial with embedded process evaluation. Participants were randomly assigned in a one-to-one ratio to the usual care group or the 12-month Web-based weight loss intervention, including dietitian and exercise expert feedback. Face-to-face recruitment and assessment were performed by the researcher unblinded. Data collected included weight, height, body mass index (BMI), and waist circumference, together with an audit trail of eligibility, recruitment, retention, and adherence rates. A process evaluation (website use data and qualitative interviews) monitored adherence, acceptability, and feasibility of the intervention. RESULTS: General practice database searches achieved the recruitment target (n=61) for the population of men with type 2 diabetes, of whom 66% (40/61) completed 3-month follow-up measurements. By 12 months, the retention rate was 52% (32/61), with 12 of the 33 men allocated to the intervention group still active on the website. The intervention was seen as acceptable by the majority of participants. We gained insights about acceptability and use of the website from the parallel process evaluation. CONCLUSIONS: Recruitment to the Web-based weight loss intervention was successful. Results are descriptive, but there were positive indications of increased weight loss (in kilograms and as a percentage), and reduced waist circumference and BMI for the intervention group from 3 to 12 months, in comparison with control. This research adds to the evidence base in relation to incorporating a Web-based weight loss intervention within the UK National Health Service (NHS). NHS weight loss services are struggling to provide sufficient referrals. Therefore, alternative modes of delivery, with the potential to reduce health professional input and time per patient while still enabling individual and tailored care, need to be investigated to identify whether they can be effective and thus benefit the NHS.

PMID- 30291101 TI - Establishing a Demographic, Development and Environmental Geospatial Surveillance Platform in India: Planning and Implementation. AB - BACKGROUND: Inadequate administrative health data, suboptimal public health infrastructure, rapid and unplanned urbanization, environmental degradation, and poor penetration of information technology make the tracking of health and well being of populations and their social determinants in the developing countries challenging. Technology-integrated comprehensive surveillance platforms have the potential to overcome these gaps. OBJECTIVE: This paper provides methodological insights into establishing a geographic information system (GIS)-integrated, comprehensive surveillance platform in rural North India, a resource-constrained setting. METHODS: The International Clinical Epidemiology Network Trust International established a comprehensive SOMAARTH Demographic, Development, and Environmental Surveillance Site (DDESS) in rural Palwal, a district in Haryana, North India. The surveillance platform evolved by adopting four major steps: (1) site preparation, (2) data construction, (3) data quality assurance, and (4) data update and maintenance system. Arc GIS 10.3 and QGIS 2.14 software were employed for geospatial data construction. Surveillance data architecture was built upon the geospatial land parcel datasets. Dedicated software (SOMAARTH-1) was developed for handling high volume of longitudinal datasets. The built infrastructure data pertaining to land use, water bodies, roads, railways, community trails, landmarks, water, sanitation and food environment, weather and air quality, and demographic characteristics were constructed in a relational manner. RESULTS: The comprehensive surveillance platform encompassed a population of 0.2 million individuals residing in 51 villages over a land mass of 251.7 sq km having 32,662 households and 19,260 nonresidential features (cattle shed, shops, health, education, banking, religious institutions, etc). All land parcels were assigned georeferenced location identification numbers to enable space and time monitoring. Subdivision of villages into sectors helped identify socially homogenous community clusters (418/676, 61.8%, sectors). Water and hygiene parameters of the whole area were mapped on the GIS platform and quantified. Risk of physical exposure to harmful environment (poor water and sanitation indicators) was significantly associated with the caste of individual household (P=.001), and the path was mediated through the socioeconomic status and density of waste spots (liquid and solid) of the sector in which these households were located. Ground-truthing for ascertaining the land parcel level accuracies, community involvement in mapping exercise, and identification of small habitations not recorded in the administrative data were key learnings. CONCLUSIONS: The SOMAARTH DDESS experience allowed us to document and explore dynamic relationships, associations, and pathways across multiple levels of the system (ie, individual, household, neighborhood, and village) through a geospatial interface. This could be used for characterization and monitoring of a wide range of proximal and distal determinants of health. PMID- 30291104 TI - Can patient and carers' experiences shape services? AB - Dementia is an increasingly recognised medical condition which, towards its later stages, leads to the manifestation of symptoms that often require palliation. Hospice admission for patients with dementia has been shown to increase caregiver satisfaction. Yet, admission can be harmful for the patient. This feature follows the case of one patient, Mr Smith, who was admitted to Royal Trinity Hospice (RTH) for symptom control, along with providing respite for his carers. Shortly into Mr Smith's admission, he became increasingly agitated and was ultimately discharged home. After investigating the cause of early discharge, it was concluded that the newly built, modernised private rooms were in fact very dissimilar to the homes of patients with dementia. Adapting the clinical environment to improve patient and carer satisfaction has been explored in numerous studies. Significant amendments used by hospices and care homes include bold signs and natural lighting to facilitate way-finding, in addition to vintage furnishings to create a sense of familiarity. Taking recent evidence into consideration, RTH designed a new dementia-friendly bay situated on the ground floor of its inpatient unit. Since then, many other patients with dementia have been admitted to the hospice, one being Mr Thomas. Unlike Mr Smith, Mr Thomas was much more relaxed during his admission and his wife commented on how pleased she was with his care. This feature demonstrates the importance of being receptive to feedback and identifying the need for change. PMID- 30291105 TI - Implications of epigenetic drift in colorectal neoplasia. AB - Many normal tissues undergo age-related drift in DNA methylation, providing a quantitative measure of tissue age. Here we identify and validate 781 CpG-islands (CGI) that undergo significant methylomic drift in 232 normal colorectal tissues and show that these CGI continue to drift in neoplasia while retaining significant correlations across samples. However, compared with normal colon, this drift advanced (~3-4 fold) faster in neoplasia, consistent with increased cell proliferation during neoplastic progression. The observed drift patterns were broadly consistent with modeled adenoma-carcinoma sojourn time distributions from colorectal cancer (CRC) incidence data. These results support the hypothesis that, beginning with the founder premalignant cell, cancer precursors frequently sojourn for decades before turning into cancer, implying that the founder cell typically arises early in life. At least 77-89% of the observed drift variance in distal and rectal tumors was explained by stochastic variability associated with neoplastic progression, while only 55% of the variance was explained for proximal tumors. However, gene-CGI pairs in the proximal colon that underwent drift were significantly and primarily negatively correlated with cancer gene expression, suggesting that methylomic drift participates in the clonal evolution of CRC. Methylomic drift advanced in colorectal neoplasia consistent with extended sojourn time distributions, which accounts for a significant fraction of epigenetic heterogeneity in CRC. Importantly, these estimated long-duration premalignant sojourn times suggest that early dietary and lifestyle interventions may be more effective than later changes in reducing CRC incidence. PMID- 30291107 TI - Multi-environment Genomic Prediction of Plant Traits Using Deep Learners with Dense Architecture. AB - Genomic selection is revolutionizing plant breeding and therefore methods that improve prediction accuracy are useful. For this reason, active research is being conducted to build and test methods from other areas and adapt them to the context of genomic selection. In this paper we explore the novel deep learning (DL) methodology in the context of genomic selection. We compared DL methods with densely connected network architecture to one of the most often used genome enabled prediction models: Genomic Best Linear Unbiased Prediction (GBLUP). We used nine published real genomic data sets to compare a fraction of all possible deep learning models to obtain a "meta picture" of the performance of DL methods with densely connected network architecture. In general, the best predictions were obtained with the GBLUP model when genotype*environment interaction (G*E) was taken into account (8 out of 9 data sets); when the interactions were ignored, the DL method was better than the GBLUP in terms of prediction accuracy in 6 out of the 9 data sets. For this reason, we believe that DL should be added to the data science toolkit of scientists working on animal and plant breeding. This study corroborates the view that there are no universally best prediction machines. PMID- 30291108 TI - Multi-trait, Multi-environment Deep Learning Modeling for Genomic-Enabled Prediction of Plant Traits. AB - Multi-trait and multi-environment data are common in animal and plant breeding programs. However, what is lacking are more powerful statistical models that can exploit the correlation between traits to improve prediction accuracy in the context of genomic selection (GS). Multi-trait models are more complex than univariate models and usually require more computational resources, but they are preferred because they can exploit the correlation between traits, which many times helps improve prediction accuracy. For this reason, in this paper we explore the power of multi-trait deep learning (MTDL) models in terms of prediction accuracy. The prediction performance of MTDL models was compared to the performance of the Bayesian multi-trait and multi-environment (BMTME) model proposed by Montesinos-Lopez et al. (2016), which is a multi-trait version of the genomic best linear unbiased prediction (GBLUP) univariate model. Both models were evaluated with predictors with and without the genotype environment interaction term. The prediction performance of both models was evaluated in terms of Pearson's correlation using cross-validation. We found that the best predictions in two of the three data sets were found under the BMTME model, but in general the predictions of both models, BTMTE and MTDL, were similar. Among models without the genotype environment interaction, the MTDL model was the best, while among models with genotype environment interaction, the BMTME model was superior. These results indicate that the MTDL model is very competitive for performing predictions in the context of GS, with the important practical advantage that it requires less computational resources than the BMTME model. PMID- 30291109 TI - Role of Cis, Trans, and Inbreeding Effects on Meiotic Recombination in Saccharomyces cerevisiae. AB - Meiotic recombination is a major driver of genome evolution by creating new genetic combinations. To probe the factors driving variability of meiotic recombination, we used a high-throughput method to measure recombination rates in hybrids between SK1 and a total of 26 Saccharomyces cerevisiae strains from different geographic origins and habitats. Fourteen intervals were monitored for each strain, covering chromosomes VI and XI entirely, and part of chromosome I. We found an average number of crossovers per chromosome ranging between 1.0 and 9.5 across strains ("domesticated" or not), which is higher than the average between 0.5 and 1.5 found in most organisms. In the different intervals analyzed, recombination showed up to ninefold variation across strains but global recombination landscapes along chromosomes varied less. We also built an incomplete diallel experiment to measure recombination rates in one region of chromosome XI in 10 different crosses involving five parental strains. Our overall results indicate that recombination rate is increasingly positively correlated with sequence similarity between homologs (i) in DNA double-strand break-rich regions within intervals, (ii) in entire intervals, and (iii) at the whole genome scale. Therefore, these correlations cannot be explained by cis effects only. We also estimated that cis and trans effects explained 38 and 17%, respectively, of the variance of recombination rate. In addition, by using a quantitative genetics analysis, we identified an inbreeding effect that reduces recombination rate in homozygous genotypes, while other interaction effects (specific combining ability) or additive effects (general combining ability) are found to be weak. Finally, we measured significant crossover interference in some strains, and interference intensity was positively correlated with crossover number. PMID- 30291110 TI - Integration of Stress Signaling in Caenorhabditis elegans Through Cell Nonautonomous Contributions of the JNK Homolog KGB-1. AB - Dealing with physiological stress is a necessity for all organisms, and the pathways charged with this task are highly conserved in Metazoa . Accumulating evidence highlights cell-nonautonomous activation as an important mode of integrating stress responses at the organism level. Work in Caenorhabditis elegans highlighted the importance of such regulation for the unfolded protein response (UPR) and for gene expression downstream of the longevity-associated transcription factor DAF-16 Here we describe a role for the JNK homolog KGB-1 in cell-nonautonomous regulation of these two response modules. KGB-1 protects developing larvae from heavy metals and from protein folding stress (which we found to be independent of canonical UPR pathways), but sensitizes adults to the same stress, further shortening life span under normal conditions. This switch is associated with age-dependent antagonistic regulation of DAF-16 Using transgenic tissue-specific KGB-1 expression or tissue-specific KGB-1 activation we examined the contributions of KGB-1 to gene regulation, stress resistance, and life span. While cell-autonomous contributions were observed, particularly in the epidermis, cell-nonautonomous contributions of neuronal KGB-1 (and also in muscle) were effective in driving intestinal gene induction, age-dependent regulation of intestinal DAF-16, and stress resistance, and did not require KGB-1 expression in the target tissue. Additional genetic analyses revealed requirement for UNC-13 in mediating neuronal contributions, indicating involvement of neurotransmission. Our results expand the role of KGB-1 in stress responses from providing local cellular protection to integrating stress responses at the level of the whole organism. PMID- 30291106 TI - Management of Hyperglycemia in Type 2 Diabetes, 2018. A Consensus Report by the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD). AB - The American Diabetes Association and the European Association for the Study of Diabetes convened a panel to update the prior position statements, published in 2012 and 2015, on the management of type 2 diabetes in adults. A systematic evaluation of the literature since 2014 informed new recommendations. These include additional focus on lifestyle management and diabetes self-management education and support. For those with obesity, efforts targeting weight loss, including lifestyle, medication, and surgical interventions, are recommended. With regards to medication management, for patients with clinical cardiovascular disease, a sodium-glucose cotransporter 2 (SGLT2) inhibitor or a glucagon-like peptide 1 (GLP-1) receptor agonist with proven cardiovascular benefit is recommended.

PMID- 30291111 TI - Proteomic profiling identifies outcome-predictive markers in patients with peripheral T-cell lymphoma, not otherwise specified. AB - Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) constitutes a heterogeneous category of lymphomas, which do not fit into any of the specifically defined T-cell lymphoma entities. Both the pathogenesis and tumor biology in PTCL-NOS are poorly understood. Protein expression in pretherapeutic PTCL-NOS tumors was analyzed by proteomics. Differentially expressed proteins were compared in 3 distinct scenarios: (A) PTCL-NOS tumor tissue (n = 18) vs benign lymphoid tissue (n = 8), (B) clusters defined by principal component analysis (PCA), and (C) tumors from patients with chemosensitive vs refractory PTCL-NOS. Selected differentially expressed proteins identified by proteomics were correlated with clinico-pathological features and outcome in a larger cohort of patients with PTCL-NOS (n = 87) by immunohistochemistry (IHC). Most proteins with altered expression were identified comparing PTCL-NOS vs benign lymphoid tissue. PCA of the protein profile defined 3 distinct clusters. All benign samples clustered together, whereas PTCL-NOS tumors separated into 2 clusters with different patient overall survival rates (P = .001). Differentially expressed proteins reflected large biological diversity among PTCL-NOS, particularly associated with alterations of "immunological" pathways. The 2 PTCL NOS subclusters defined by PCA showed disturbance of "stress-related" and "protein metabolic" pathways. alpha-Enolase 1 (ENO1) was found differentially expressed in all 3 analyses, and high intratumoral ENO1 expression evaluated by IHC correlated with poor outcome (hazard ratio, 2.09; 95% confidence interval, 1.17-3.73; P = .013). High expression of triosephosphate isomerase (TPI1) also showed a tendency to correlate with poor survival (P = .057). In conclusion, proteomic profiling of PTCL-NOS provided evidence of markedly altered protein expression and identified ENO1 as a novel potential prognostic marker. PMID- 30291112 TI - Eculizumab in cold agglutinin disease (DECADE): an open-label, prospective, bicentric, nonrandomized phase 2 trial. AB - Cold agglutinin disease (CAD) is a complement-dependent disorder, with extravascular and intravascular hemolysis resulting from initial or terminal complement activation, respectively. We tested the efficacy and safety of eculizumab, an inhibitor of the terminal complement pathway. Treatment-requiring patients received 600 mg eculizumab weekly for 4 weeks, followed 1 week later by 900 mg every other week through week 26. The primary end point was the difference in the lactate dehydrogenase level between the first and the last day of therapy. Twelve patients with chronic CAD and 1 patient with an acute cold agglutinin syndrome were included. The median lactate dehydrogenase level decreased from 572 U/L (interquartile range [IQR], 534-685) to 334 U/L (IQR, 243-567; P = .0215), paralleled by an increase in hemoglobin from 9.35 g/dL (IQR, 8.80-10.80) to 10.15 g/dL (IQR, 9.00-11.35; P = .0391; Wilcoxon signed-rank test). Three patients maintained and 8 patients acquired transfusion independence, and 1 patient each showed a reduced or increased transfusion requirement, respectively (P = .0215; exact McNemar's test). Patients with cold agglutinins with a thermal amplitude of 37 degrees C tended to have less pronounced lactate dehydrogenase responses than patients with cold agglutinins with narrower thermal amplitudes. In the latter, responses were observed at lower serum levels of eculizumab than they were in the former. In contrast to hemolysis, cold-induced circulatory symptoms remained unaffected. In conclusion, eculizumab significantly reduced hemolysis and transfusion requirement in patients with CAD. Suppression of hemolysis caused by cold agglutinins with a wide thermal amplitude may require higher eculizumab doses than used here. The trial is registered with EudraCT (#2009-016966-97) and www.clinicaltrials.gov (#NCT01303952).

AB - New-onset autoimmune hemolytic anemia (AIHA) occurs in 2% to 6% of pediatric patients post-hematopoietic stem cell transplantation (HSCT) and is a significant complication.

In potentially life-threatening AIHA in the context of HSCT, daratumumab may be an effective rescue therapy. PMID- 30291114 TI - Incremental Elevations in TNFalpha and IL6 in the Human Colon and Procancerous Changes in the Mucosal Transcriptome Accompany Adiposity. AB - BACKGROUND: Obesity, a risk factor for colorectal cancer, raises systemic levels of proinflammatory mediators. Whether increased levels also reside in the colons of obese individuals and are accompanied by procancerous alterations in the mucosal transcriptome is unknown. METHODS: Concentrations of TNFalpha, IL1beta, and IL6 in blood and colonic mucosa of 16 lean and 26 obese individuals were examined. Differences in the mucosal transcriptome between the two groups were defined. RESULTS: Plasma IL6 and TNFalpha were 1.4- to 3-fold elevated in obese subjects [body mass index (BMI) >= 34 kg/m2] compared with the lean controls (P < 0.01). Among individuals with BMI >= 34 kg/m2 colonic concentrations of IL6 and TNFalpha were 2- to 3-fold greater than in lean subjects (P < 0.03). In a general linear model, adjusted for NSAID use, colonic IL6 (partial r = 0.41; P < 0.01) and TNFalpha (partial r = 0.41; P = 0.01) increased incrementally over the entire range of BMIs (18.1-45.7). Regular use of nonsteroidal anti-inflammatory drugs (NSAIDs) was associated with a reduction in colonic IL6 (beta = -0.65, P < 0.02). RNA sequencing (NSAID users excluded) identified 182 genes expressed differentially between lean and obese subjects. The two gene networks most strongly linked to changes in expression included several differentially expressed genes known to regulate the procarcinogenic signaling pathways, NFkappaB and ERK 1/2, in a pattern consistent with upregulation of each in the obese subjects. CONCLUSIONS: Incremental increases in two major proinflammatory colonic cytokines are associated with increasing BMI, and in the obese state are accompanied by procancerous changes in the transcriptome. IMPACT: These observations delineate means by which an inflammatory milieu may contribute to obesity-promoted colon cancer. PMID- 30291115 TI - Primary Colonizing Betaproteobacteriales Play a Key Role in the Growth of Legionella pneumophila in Biofilms on Surfaces Exposed to Drinking Water Treated by Slow Sand Filtration. AB - Slow sand filtration with extensive pretreatment reduces the microbial growth potential of drinking water to a minimum level at four surface water supplies in The Netherlands. The potential of these slow sand filtrates (SSFs) to promote microbial growth in warm tap water installations was assessed by measuring biofilm formation and growth of Legionella bacteria on glass and chlorinated polyvinylchloride (CPVC) surfaces exposed to SSFs at 37 +/- 2 degrees C in a model system for up to six months. The steady-state biofilm concentration ranged from 230 to 3,980 pg ATP cm-2 on glass and 1.4 (+/-0.3)-times-higher levels on CPVC. These concentrations correlated significantly with the assimilable organic carbon (AOC) concentrations of the warm water (8 to 24 ug acetate-C equivalents [ac-C eq] liter-1), which were raised about 2 times by mixing cold and heated (70 degrees C) SSFs. All biofilms supported growth of Legionella pneumophila with maximum concentrations ranging from 6 * 102 to 1.5 * 105 CFU cm-2 Biofilms after <=50 days of exposure were predominated by Betaproteobacteriales, mainly Piscinibacter, Caldimonas, Methyloversatilis, and an uncultured Rhodocyclaceae bacterium. These rapidly growing primary colonizers most likely served as prey for the host amoebae of L. pneumophila Alphaproteobacteria, mostly Xanthobacteraceae, e.g., Bradyrhizobium, Pseudorhodoplanes, and other amoeba resistant bacteria, accounted for 37.5% of the clones retrieved. A conceptual model based on a quadratic relationship between the L. pneumophila colony count and the biofilm concentration under steady-state conditions is used to explain the variations in the Legionella CFU pg-1 ATP ratios in the biofilms.IMPORTANCE Proliferation of L. pneumophila in premise plumbing poses a public health threat. Extended water treatment using physicochemical and biofiltration processes, including slow sand filtration, at four surface water supplies in The Netherlands reduces the microbial growth potential of the treated water to a minimum level, and the distributed drinking water complies with high quality standards. However, heating of the water in warm tap water installations increases the concentration of easily assimilable organic compounds, thereby promoting biofilm formation and growth of L. pneumophila Prevention of biofilm formation in plumbing systems by maintenance of a disinfectant residual during distribution and/or further natural organic matter (NOM) removal is not feasible in the supplies studied. Temperature management in combination with optimized hydraulics and material selection are therefore essential to prevent growth of L. pneumophila in premise plumbing systems. Still, reducing the concentration of biodegradable compounds in drinking water by appropriate water treatment is important for limiting the Legionella growth potential. PMID- 30291116 TI - Lavender Decline in France Is Associated with Chronic Infection by Lavender Specific Strains of "Candidatus Phytoplasma solani". AB - Lavender decline compromises French lavender production, and preliminary data have suggested the involvement of "Candidatus Phytoplasma solani" in the etiology of the disease. In order to evaluate the epidemiological role of "Ca Phytoplasma solani," a 3-year survey was conducted in southeastern France. "Ca Phytoplasma solani" was detected in 19 to 56% of the declining plants, depending on seasons and cultivars, and its prevalence was correlated with symptom severity. Autumn was more favorable than spring for phytoplasma detection, and "Ca Phytoplasma solani" incidence was higher in Lavandula angustifolia than in Lavandula intermedia hybrids. Detection of the phytoplasma fluctuated over months, supporting the chronicity of infection. Three "Ca Phytoplasma solani" secY genotypes, S17, S16, and S14, were the most prevalent in lavender fields and were also detected in nurseries, whereas strains detected in surrounding bindweed and wild carrots were mostly of the S1 and S4 genotypes. This suggests that lavender is the main pathogen reservoir of the epidemic. Adults and nymphs of the planthopper vector Hyalesthes obsoletus were commonly captured in lavender fields and were shown to harbor mainly the prevalent phytoplasma genotypes detected in lavenders. The "Ca Phytoplasma solani" genotype S17 was transmitted to Catharanthus roseus periwinkle by naturally infected H. obsoletus Finally, the inventory of the bacterial community of declining lavenders that tested negative for "Ca Phytoplasma solani" by 16S rRNA deep sequencing ruled out the involvement of other phloem-limited bacterial pathogens.IMPORTANCE The etiology and main pathways for the spread of lavender decline, an infectious disease affecting French lavender production since the 1960s, have remained unclear, hampering the development of efficient control strategies. An extensive survey of lavender fields led to the conclusion that "Candidatus Phytoplasma solani" was chronically infecting declining lavenders and was associated with large infectious populations of Hyalesthes obsoletus planthoppers living on the crop itself. Lavender appeared to be the main reservoir host for lavender-specific phytoplasma strains, an unusual feature for this phytoplasma, which usually propagates from reservoir weeds to various economically important crops. These results point out the necessity to protect young lavender fields from the initial phytoplasma inoculum coming from surrounding lavender fields or from infected nurseries and to promote agricultural practices that reduce the development of H. obsoletus vector populations. PMID- 30291117 TI - Behavior of Foodborne Pathogens Listeria monocytogenes and Staphylococcus aureus in Mixed-Species Biofilms Exposed to Biocides. AB - In nature and man-made environments, microorganisms reside in mixed-species biofilms, in which the growth and metabolism of an organism are different from these behaviors in single-species biofilms. Pathogenic microorganisms may be protected against adverse treatments in mixed-species biofilms, leading to health risk for humans. Here, we developed two mixed five-species biofilms that included one or the other of the foodborne pathogens Listeria monocytogenes and Staphylococcus aureus The five species, including the pathogen, were isolated from a single food-processing environmental sample, thus mimicking the environmental community. In mature mixed five-species biofilms on stainless steel, the two pathogens remained at a constant level of ~105 CFU/cm2 The mixed five-species biofilms as well as the pathogens in monospecies biofilms were exposed to biocides to determine any pathogen-protective effect of the mixed biofilm. Both pathogens and their associate microbial communities were reduced by peracetic acid treatments. S. aureus decreased by 4.6 log cycles in monospecies biofilms, but the pathogen was protected in the five-species biofilm and decreased by only 1.1 log cycles. Sessile cells of L. monocytogenes were affected to the same extent when in a monobiofilm or as a member of the mixed-species biofilm, decreasing by 3 log cycles when exposed to 0.0375% peracetic acid. When the pathogen was exchanged in each associated microbial community, S. aureus was eradicated, while there was no significant effect of the biocide on L. monocytogenes or the mixed community. This indicates that particular members or associations in the community offered the protective effect. Further studies are needed to clarify the mechanisms of biocide protection and to identify the species playing the protective role in microbial communities of biofilms.IMPORTANCE This study demonstrates that foodborne pathogens can be established in mixed-species biofilms and that this can protect them from biocide action. The protection is not due to specific characteristics of the pathogen, here S. aureus and L. monocytogenes, but likely caused by specific members or associations in the mixed-species biofilm. Biocide treatment and resistance are a challenge for many industries, and biocide efficacy should be tested on microorganisms growing in biofilms, preferably mixed systems, mimicking the application environment. PMID- 30291118 TI - Effective Soil Extraction Method for Cultivating Previously Uncultured Soil Bacteria. AB - Here, a new medium, named intensive soil extract medium (ISEM), based on new soil extract (NSE) using 80% methanol, was used to efficiently isolate previously uncultured bacteria and new taxonomic candidates, which accounted for 49% and 55% of the total isolates examined (n = 258), respectively. The new isolates were affiliated with seven phyla (Proteobacteria, Acidobacteria, Firmicutes, Actinobacteria, Verrucomicrobia, Planctomycetes, and Bacteroidetes). The result of chemical analysis showed that NSE included more diverse components of low molecular-weight organic substances than two conventional soil extracts made using distilled water. Cultivation of previously uncultured bacteria is expected to extend knowledge through the discovery of new phenotypic, physiological, and functional properties and even roles of unknown genes.IMPORTANCE Both metagenomics and single-cell sequencing can detect unknown genes from uncultured microbial strains in environments, and either method may find the significant potential metabolites and roles of these strains. However, such gene/genome-based techniques do not allow detailed investigations that are possible with cultures. To solve this problem, various approaches for cultivation of uncultured bacteria have been developed, but there are still difficulties in maintaining pure cultures by subculture. PMID- 30291119 TI - A Simple In Vitro Gut Model for Studying the Interaction between Escherichia coli and the Intestinal Commensal Microbiota in Cecal Mucus. AB - A novel in vitro gut model was developed to better understand the interactions between Escherichia coli and the mouse cecal mucus commensal microbiota. The gut model is simple and inexpensive while providing an environment that in large part replicates the non-adherent mucus layer of the mouse cecum. 16S ribosomal RNA gene profiling of the cecal microbial communities of streptomycin-treated mice colonized with E. coli MG1655 or E. coli Nissle 1917 and the gut model confirmed that the gut model properly reflected the community structure of the mouse intestine. Furthermore, the in vitro gut model mimics the results of published in vivo competitive colonization experiments. The gut model is initiated by colonization of streptomycin treated mice, then the community is serially transferred in microcentrifuge tubes in an anaerobic environment generated in anaerobe jars. The nutritional makeup of the cecum is simulated in the gut model by using a medium consisting of porcine mucin, mouse cecal mucus, HEPES-Hanks buffer (pH 7.2), Cleland's reagent, and agarose. Agarose was found to be essential for maintaining stability of the microbial community in the gut model. The outcome of competitions between E. coli strains in the in vitro gut model are readily explained by the "restaurant hypothesis" of intestinal colonization. This simple model system potentially can be used to more fully understand how different members of the microbiota interact physically and metabolically during colonization of the intestinal mucus layer.Importance Both commensal and pathogenic strains of Escherichia coli appear to colonize the mammalian intestine by interacting physically and metabolically with other members of the microbiota in the mucus layer that overlays the cecal and colonic epithelium. However, the use of animal models and complexity of the mammalian gut make it difficult to isolate experimental variables that could dictate the interactions between E. coli and other members of the microbiota, such as those that are critical for successful colonization. Here we describe a simple and relatively inexpensive in vitro gut model that in large part mimics in vivo conditions, and therefore can facilitate the manipulation of experimental variables for studying interactions of E.coli with the intestinal microbiota. PMID- 30291120 TI - Response of the Anaerobic Methanotroph "Candidatus Methanoperedens nitroreducens" to Oxygen Stress. AB - "Candidatus Methanoperedens nitroreducens" is an archaeon that couples the anaerobic oxidation of methane to nitrate reduction. In natural and man-made ecosystems, this archaeon is often found at oxic-anoxic interfaces where nitrate, the product of aerobic nitrification, cooccurs with methane produced by methanogens. As such, populations of "Ca Methanoperedens nitroreducens" could be prone to regular oxygen exposure. Here, we investigated the effect of 5% (vol/vol) oxygen exposure in batch activity assays on a "Ca Methanoperedens nitroreducens" culture, enriched from an Italian paddy field. Metagenome sequencing of the DNA extracted from the enrichment culture revealed that 83% of 16S rRNA gene reads were assigned to a novel strain, "Candidatus Methanoperedens nitroreducens Verserenetto." RNA was extracted, and metatranscriptome sequencing upon oxygen exposure revealed that the active community changed, most notably in the appearance of aerobic methanotrophs. The gene expression of "Ca Methanoperedens nitroreducens" revealed that the key genes encoding enzymes of the methane oxidation and nitrate reduction pathways were downregulated. In contrast to this, we identified upregulation of glutaredoxin, thioredoxin family/like proteins, rubrerythrins, peroxiredoxins, peroxidase, alkyl hydroperoxidase, type A flavoproteins, FeS cluster assembly protein, and cysteine desulfurases, indicating the genomic potential of "Ca Methanoperedens nitroreducens Verserenetto" to counteract the oxidative damage and adapt in environments where they might be exposed to regular oxygen intrusion.IMPORTANCE "Candidatus Methanoperedens nitroreducens" is an anaerobic archaeon which couples the reduction of nitrate to the oxidation of methane. This microorganism is present in a wide range of aquatic environments and man-made ecosystems, such as paddy fields and wastewater treatment systems. In such environments, these archaea may experience regular oxygen exposure. However, "Ca Methanoperedens nitroreducens" is able to thrive under such conditions and could be applied for the simultaneous removal of dissolved methane and nitrogenous pollutants in oxygen-limited systems. To understand what machinery "Ca Methanoperedens nitroreducens" possesses to counteract the oxidative stress and survive, we characterized the response to oxygen exposure using a multi-omics approach. PMID- 30291121 TI - Improvement of ST0452 N-Acetylglucosamine-1-Phosphate Uridyltransferase Activity by the Cooperative Effect of Two Single Mutations Identified through Structure Based Protein Engineering. AB - We showed previously that the Y97N mutant of the ST0452 protein, isolated from Sulfolobus tokodaii, exhibited over 4 times higher N-acetylglucosamine-1 phosphate (GlcNAc-1-P) uridyltransferase (UTase) activity, compared with that of the wild-type ST0452 protein. We determined the three-dimensional structure of the Y97N protein to explore the detailed mechanism underlying this increased activity. The overall structure was almost identical to that of the wild-type ST0452 protein (PDB ID 2GGO), with residue 97 (Asn) interacting with the O-5 atom of N-acetylglucosamine (GlcNAc) in the complex without metal ions. The same interaction was observed for Escherichia coli GlmU in the absence of metal ions. These observations indicated that the three-dimensional structure of the Y97N protein was not changed by this substitution but the interactions with the substrate were slightly modified, which might cause the activity to increase. The crystal structure of the Y97N protein also showed that positions 146 (Glu) and 80 (Thr) formed interactions with GlcNAc, and an engineering strategy was applied to these residues to increase activity. All proteins substituted at position 146 had drastically decreased activities, whereas several proteins substituted at position 80 showed higher GlcNAc-1-P UTase activity, compared to that of the wild type protein. The substituted amino acids at positions 80 and 97 might result in optimized interactions with the substrate; therefore, we predicted that the combination of these two substitutions might cooperatively increase GlcNAc-1-P UTase activity. Of the four double mutant ST0452 proteins generated, T80S/Y97N showed 6.5-times-higher activity, compared to that of the wild-type ST0452 protein, revealing that these two substituted residues functioned cooperatively to increase GlcNAc-1-P UTase activity.IMPORTANCE We demonstrated that the enzymatic activity of a thermostable protein was over 4 times higher than that of the wild-type protein following substitution of a single amino acid, without affecting its thermostability. The three-dimensional structure of the improved mutant protein complexed with substrate was determined. The same overall structure and interaction between the substituted residue and the GlcNAc substrate as observed in the well-characterized bacterial enzyme suggested that the substitution of Tyr at position 97 by Asn might slightly change the interaction. This subtle change in the interaction might potentially increase the GlcNAc-1-P UTase activity of the mutant protein. These observations indicated that a drastic change in the structure of a natural thermostable enzyme is not necessary to increase its activity; a subtle change in the interaction with the substrate might be sufficient. Cooperative effects were observed in the appropriate double mutant protein. This work provides useful information for the future engineering of natural enzymes. PMID- 30291122 TI - Feammox Acidimicrobiaceae sp. A6, a lithoautotrophic electrode-colonizing bacterium. AB - An Acidimicrobiaceae sp. A6 (A6), from the Actinobacteria phylum was recently identified as a microorganism that can carry out anaerobic ammonium oxidation coupled to iron reduction, a process also known as Feammox. Being an iron reducing bacterium, A6 was studied as a potential electrode-reducing bacterium that may transfer electrons extracellularly onto electrodes while gaining energy from ammonium oxidation. Actinobacteria species have been overlooked as electrogenic bacteria, and the importance of lithoautotrophic iron-reducers as electrode-reducing bacteria at anodes has not been addressed. By installing electrodes in soil of a forested riparian wetland where A6 thrives, in soil columns in the laboratory, as well as in A6 bioaugmented constructed wetland (CW) mesocosms, and finally operating microbial electrolysis (MECs) cells with pure A6 culture, characteristics and performances of this organism as an electrode reducing bacterium candidate were investigated. In this study, we show that Acidimicrobiaceae sp. A6, a lithoautotrophic bacterium, is capable of colonizing electrodes under controlled conditions. In addition, A6 appears to be an electrode-reducing bacterium since current production was boosted shortly after the CWs were seeded with enrichment A6 culture, and current production was detected in MECs operated with pure A6, with the anode as the sole electron acceptor and NH4 + as the sole electron donor.IMPORTANCE Most studies on electrogenic microorganisms have focused on the most abundant heterotrophs, while other microorganisms also commonly present in electrode microbial communities such as Actinobacteria have been overlooked. The novel Acidimicrobiaceae sp. A6 (Actinobacteria) is an iron-reducing bacterium that can colonize the surface of anodes and is linked to electrical current production, making it an electrode reducing bacteria candidate. Furthermore, A6 can carry out anaerobic ammonium oxidation coupled to iron reduction, therefore, findings from this study open up the possibility of using electrodes instead of iron as electron acceptors as a mean to promote A6 to treat NH4 + containing wastewater more efficiently. Altogether, this study expands our knowledge on electrogenic bacteria and opens up the possibility to develop Feammox-based technologies coupled to bioelectric systems for the treatment of NH4 + and other contaminants in anoxic systems. PMID- 30291123 TI - Rhizosphere Microbial Response to Multiple Metal(loid)s in Different Contaminated Arable Soils Indicates Crop-Specific Metal-Microbe Interactions. AB - In this study, we sampled rhizosphere soils from seven different agricultural fields adjacent to mining areas and cultivated with different crops (corn, rice, or soybean), to study the interactions among the innate microbiota, soil chemical properties, plants, and metal contamination. The rhizosphere bacterial communities were characterized by Illumina sequencing of the 16S rRNA genes, and their interactions with the local environments, including biotic and abiotic factors, were analyzed. Overall, these soils were heavily contaminated with multiple metal(loid)s, including V, Cr, Cu, Sb, Pb, Cd, and As. The interactions between environmental parameters and microbial communities were identified using multivariate regression tree analysis, canonical correspondence analysis, and network analysis. Notably, metal-microbe interactions were observed to be crop specific. The rhizosphere communities were strongly correlated with V and Cr levels, although these sites were contaminated from Sb and Zn/Pb mining, suggesting that these two less-addressed metals may play important roles in shaping the rhizosphere microbiota. Members of Gaiellaceae cooccurred with other bacterial taxa (biotic interactions) and several metal(loid)s, suggesting potential metal(loid) resistance or cycling involving this less-well-known taxon.IMPORTANCE The rhizosphere is the "hub" for plant-microbe interactions and an active region for exchange of nutrients and energy between soil and plants. In arable soils contaminated by mining activities, the rhizosphere may be an important barrier resisting metal uptake. Therefore, the responses of the rhizosphere microbiota to metal contamination involve important biogeochemical processes, which can affect metal bioavailability and thus impact food safety. However, understanding these processes remains a challenge. The current study illustrates that metal-microbe interactions may be crop specific and some less addressed metals, such as V and Cr, may play important roles in shaping bacterial communities. The current study provides new insights into metal-microbe interactions and contributes to future implementation and monitoring efforts in contaminated arable soils.

AB - Ly6Chi monocytes migrate to injured sites and induce inflammation in the acute phase of tissue injury. However, once the causes of tissue injury are eliminated, monocyte-derived macrophages contribute to the resolution of inflammation and tissue repair. It remains unclear whether the emergence of these immunoregulatory macrophages is attributed to the phenotypic conversion of inflammatory monocytes in situ or to the recruitment of bone marrow-derived regulatory cells de novo. Here, we identified a subpopulation of Ly6Chi monocytes that contribute to the resolution of inflammation and tissue repair. Ym1+Ly6Chi monocytes greatly expanded in bone marrow during the recovery phase of systemic inflammation or tissue injury. Ym1+Ly6Chi monocytes infiltrating into an injured site exhibited immunoregulatory and tissue-reparative phenotypes. Deletion of Ym1+Ly6Chi monocytes resulted in delayed recovery from colitis. These results demonstrate that a distinct monocyte subpopulation destined to act in immunoregulation is generated in bone marrow and participates in resolution of inflammation and tissue repair. PMID- 30291131 TI - The cysteinyl leukotriene 3 receptor regulates expansion of IL-25-producing airway brush cells leading to type 2 inflammation. AB - Respiratory epithelial cells (EpCs) orchestrate airway mucosal inflammation in response to diverse environmental stimuli, but how distinct EpC programs are regulated remains poorly understood. Here, we report that inhalation of aeroallergens leads to expansion of airway brush cells (BrCs), specialized chemosensory EpCs and the dominant epithelial source of interleukin-25 (IL-25). BrC expansion was attenuated in mice lacking either LTC4 synthase, the biosynthetic enzyme required for cysteinyl leukotriene (CysLT) generation, or the EpC receptor for leukotriene E4 (LTE4), CysLT3R. LTE4 inhalation was sufficient to elicit CysLT3R-dependent BrC expansion in the murine airway through an IL-25 dependent but STAT6-independent signaling pathway. Last, blockade of IL-25 attenuated both aeroallergen and LTE4-elicited CysLT3R-dependent type 2 lung inflammation. These results demonstrate that CysLT3R senses the endogenously generated lipid ligand LTE4 and regulates airway BrC number and function.

PMID- 30291136 TI - Prevalence of cystoid macular oedema, epiretinal membrane and cataract in retinitis pigmentosa. AB - BACKGROUND/AIMS: To report the prevalence of treatable complications (cystoid macular oedema, CME; epiretinal membrane, ERM and cataract) in patients with retinitis pigmentosa (RP). METHODS: Consecutive patients with RP attending a tertiary eye clinic in 2012. Spectral domain-optical coherence tomography was used to determine presence of CME and ERM. Clinic records were reviewed to identify cataract and pseudophakia. Multivariable analyses adjusted for age, gender and other confounders. RESULTS: Data are presented for 338 eyes from 169 patients. CME was present in 58.6% of patients and 50.9% of eyes and was bilateral in 73.7%. ERM, cataract and pseudophakia were present in 22.8%, 23.4% and 11.2% eyes, respectively. In multivariable analyses, CME was associated with younger age (OR 0.81, 95% CI 0.67 to 0.98) but not with gender. Patients with ERM and cataract/pseudophakia were less likely to also have CME (OR 0.19, 95% CI 0.09 to 0.40 and OR 0.37, 95% CI 0.16 to 0.84, respectively). CME was most prevalent in patients with autosomal-dominant inheritance (71.4%), followed by autosomal recessive/sporadic inheritance (58.9%) and least likely in persons with X linked inheritance (12.5%, p<0.001). CONCLUSIONS: The prevalence of treatable RP complications is high and suggests it may be clinically beneficial to screen patients with RP to identify those who may benefit from current or future interventions. PMID- 30291137 TI - Outcomes of cataract surgery performed by non-physician cataract surgeons in remote North Cameroon. AB - OBJECTIVE: To report the outcomes of cataract surgery performed by non-physician cataract surgeons due to lack of ophthalmologists in remote areas of North Cameroon. DESIGN: Prospective cohort study. SETTING: The main centre of the non governmental organisation Ophtalmo Sans Frontieres in Lagdo. PARTICIPANTS AND INTERVENTIONS: Age-related cataract surgery performed between 28 November 2016 and 17 May 2017. MAIN OUTCOMES MEASURES: The main outcome measure was presenting visual acuity (PVA) 1-4 weeks after surgery, classified according to the WHO as good (PVA >=6/18), borderline (PVA 6/60-6/18) and poor (PVA <6/60). The WHO definition of blindness (visual acuity <3/60) and severe visual acuity (visual acuity 3/60-6/60) was used to assess the proportion of patients with a change in WHO category. RESULTS: We included 474 eyes of 474 patients; the mean (SD) age was 63.9 (15) years (42.2% female). At 1-4 weeks after surgery, the surgical outcome was good for 170 patients (41.1%), borderline for 213 (51.5%) and poor for 31 (7.5%). In all, 224 patients (47.2%) had blindness or severe visual impairment before cataract surgery and 22 (5.3%) at 1-4 weeks after surgery. Poor visual outcome was associated with older age (p=0.018), preoperative blindness or severe impairment (p=0.012) and surgical complications (p=0.019). CONCLUSION: Blindness and severe visual impairment were significantly decreased in the early postoperative period. Poor outcomes were associated with older age, low preoperative binocular visual acuity and intraoperative complications. Non physician cataract surgeons may compensate for the lack of ophthalmologists in remote areas of low-income and middle-income countries. PMID- 30291138 TI - A critical period of susceptibility to sound in the sensory cells of cephalopod hatchlings. AB - The cephalopod statocyst and lateral line systems are sensory organs involved in orientation and balance. Lateral lines allow cephalopods to detect particle motion and are used for locating prey or predators in low light conditions. Here, we show the first analysis of damaged sensory epithelia in three species of cephalopod hatchlings (Sepia officinalis, Loligo vulgaris and Illex coindetii) after sound exposure. Our results indicate lesions in the statocyst sensory epithelia, similar to what was found in adult specimens. The novelty is that the severity of the lesions advanced more rapidly in hatchlings than in adult animals; i.e. the degree of lesions seen in hatchlings immediately after noise exposure would develop within 48 h in adults. This feature suggests a critical period of increased sensitivity to acoustic trauma in those species as has been described in developing mammalian cochlea and avian basilar papilla. The hair cells in the lateral lines of S. officinalis followed the same pattern of damage occurrence, while those of L. vulgaris and I. coindetii displayed a decreasing severity of damage after 24 h. These differences could be due to dissimilarities in size and life stages between the three species. PMID- 30291139 TI - Trends in the use of prenatal testing services for fetal aneuploidy in Ontario: a descriptive study. AB - BACKGROUND: In 2014, Ontario augmented its publicly funded multiple-marker screening program for prenatal aneuploidy by incorporating cell-free fetal DNA (cffDNA) analysis for high-risk pregnancies. We assessed trends in the use of multiple-marker screening, cffDNA screening and prenatal diagnostic testing before and after implementation of public funding. METHODS: We conducted a descriptive study based on data from the Better Outcomes Registry & Network (BORN) Ontario. The study population included all pregnant women in Ontario with a singleton pregnancy and an expected date of delivery between July 1, 2012, and Mar. 31, 2016, with pregnancy data captured in BORN. Pregnancy losses and terminations before 20 weeks' gestation not captured in BORN were excluded. We generated descriptive statistics to show trends and regional variations in use. RESULTS: The study sample included 534 210 singleton pregnancies. After cffDNA screening was funded for specific indications, uptake of multiple-marker screening increased slightly, from 66.5% to 68.1% (p < 0.001). Uptake of cffDNA screening among women with a positive multiple-marker screening result increased substantially, from 3.2% to 48.8% (p < 0.001). In contrast, the rate of prenatal diagnostic testing in this group decreased from 54.8% to 30.8% (p < 0.001). Although women aged 40 years or older are eligible for primary cffDNA screening, only a small decrease in the use of multiple-marker screening was observed in this group. The greatest use of cffDNA screening and greatest decline in prenatal diagnostic testing were seen in women with a level of risk for trisomy 21 of 1:101-1:200 based on multiple-marker screening. INTERPRETATION: After public funding of cffDNA screening was implemented in Ontario, there was a significant increase in cffDNA screening and a significant decrease in prenatal diagnostic testing among women with a positive multiple-marker screening result. These changing patterns show the significant impact of public policy and funding decisions on women's choices regarding prenatal testing.

PMID- 30291141 TI - Human DPP9 represses NLRP1 inflammasome and protects against auto-inflammatory diseases via both peptidase activity and FIIND domain binding. AB - The inflammasome is a critical molecular complex that activates IL-1 driven inflammation in response to pathogen- and danger-associated signals. Germline mutations in the inflammasome sensor, NLRP1 cause Mendelian systemic autoimmunity and skin cancer susceptibility, but its endogenous regulation remains less understood. Here we use a proteomics screen to uncover dipeptidyl dipeptidase, DPP9 as a novel interacting partner with human NLRP1 and a related inflammasome regulator, CARD8. DPP9 functions as an endogenous inhibitor of NLRP1 inflammasome in diverse primary cell types from human and mice. DPP8/9 inhibition via small molecule drugs and CRISPR/Cas9-mediated genetic deletion specifically activate human NLRP1 inflammasome, leading to ASC speck formation, pyroptotic cell death and secretion of cleaved IL-1beta. Mechanistically, DPP9 interacts with a unique auto-proteolytic domain (FIIND) found in NLRP1 and CARD8. This scaffolding function of DPP9 and its catalytic activity act synergistically to maintain NLRP1 in its inactive state and repress downstream inflammasome activation. We further identified a single patient-derived germline missense mutation in NLRP1 FIIND domain that abrogates DPP9 binding, leading to inflammasome hyper-activation seen in the Mendelian auto-inflammatory disease AIADK. These results unite recent findings on the regulation of murine Nlrp1b by Dpp8/9 and uncover a new regulatory mechanism for the NLRP1 inflammasome in primary human cells. Our results further suggest that DPP9 could be a multi-functional inflammasome regulator involved in human auto-inflammatory diseases. PMID- 30291142 TI - Inducible microRNA-590-5p inhibits host antiviral response by targeting the soluble interleukin-6 (IL6) receptor. AB - MicroRNA (miR)-590-5p has been identified as an important regulator of some signaling pathways such as cell proliferation and tumorigenesis. However, little is known about its role during viral infection. Here, we report that miR-590-5p was significantly induced by various viruses and effectively potentiated virus replication in different viral infection systems. Furthermore, miR-590-5p substantially attenuated the virus-induced expression of type I and type III interferons (IFNs) and inflammatory cytokines, resulting in impaired downstream antiviral signaling. Interleukin-6 receptor (IL6R) was identified as a target of miR-590-5p. Interestingly, the role of miR-590-5p in virus-triggered signaling was abolished in IL6R knockout cells, and this could be rescued by restoring the expression of the soluble IL6R (sIL6R) but not the membrane-bound IL6R (mIL6R), suggesting that sIL6R is indispensable for miR-590-5p in modulating the host antiviral response. Furthermore, miR-590-5p down-regulated endogenous sIL6R and mIL6R expression through a translational repression mechanism. These findings thus uncover a previously uncharacterized role and the underlying mechanism of miR-590-5p in the innate immune response to viral infection. PMID- 30291143 TI - Mechanistic basis for the evolution of chalcone synthase catalytic cysteine reactivity in land plants. AB - Flavonoids are important polyphenolic natural products, ubiquitous in land plants, that play diverse functions in plants' survival in their ecological niches, including UV protection, pigmentation for attracting pollinators, symbiotic nitrogen fixation, and defense against herbivores. Chalcone synthase (CHS) catalyzes the first committed step in plant flavonoid biosynthesis and is highly conserved in all land plants. In several previously reported crystal structures of CHSs from flowering plants, the catalytic cysteine is oxidized to sulfinic acid, indicating enhanced nucleophilicity in this residue associated with its increased susceptibility to oxidation. In this study, we report a set of new crystal structures of CHSs representing all five major lineages of land plants (bryophytes, lycophytes, monilophytes, gymnosperms, and angiosperms), spanning 500 million years of evolution. We reveal that the structures of CHS from a lycophyte and a moss species preserve the catalytic cysteine in a reduced state, in contrast to the cysteine sulfinic acid seen in all euphyllophyte CHS structures. In vivo complementation, in vitro biochemical and mutagenesis analyses, and molecular dynamics simulations identified a set of residues that differ between basal-plant and euphyllophyte CHSs and modulate catalytic cysteine reactivity. We propose that the CHS active-site environment has evolved in euphyllophytes to further enhance the nucleophilicity of the catalytic cysteine since the divergence of euphyllophytes from other vascular plant lineages 400 million years ago. These changes in CHS could have contributed to the diversification of flavonoid biosynthesis in euphyllophytes, which in turn contributed to their dominance in terrestrial ecosystems. PMID- 30291144 TI - A dominant dendrite phenotype caused by the disease-associated G253D mutation in doublecortin (DCX) is not due to its endocytosis defect. AB - Doublecortin (DCX[1]) is a protein needed for cortical development, and DCX mutations cause cortical malformations in humans. The microtubule-binding activity of DCX is well described and is important for its function, such as supporting neuronal migration and dendrite growth during development. Previous work showed that microtubule binding is not sufficient for DCX-mediated promotion of dendrite growth, and that domains in DCX's C-terminus are also required. The more C-terminal regions of DCX bind several other proteins, including the adhesion receptor neurofascin and clathrin adaptors. We recently identified a role for DCX in endocytosis of neurofascin. The disease-associated DCX-G253D mutant protein is known to be deficient in binding neurofascin, and we now asked if disruption of neurofascin endocytosis underlies the DCX-G253D-associated pathology. We first demonstrated that DCX functions in endocytosis as a complex with both the clathrin adaptor AP-2 and neurofascin: disrupting either clathrin adaptor binding (DCX-ALPA) or neurofascin binding (DCX-G253D) decreased neurofascin endocytosis in primary neurons. We then investigated a known function for DCX, namely, increasing dendrite growth in cultured neurons. Surprisingly, we found that the DCX-ALPA and DCX-G253D mutants yield distinct dendrite phenotypes. dnlike DCX-ALPA, DCX-G253D caused a dominant-negative dendrite growth phenotype. The endocytosis defect of DCX-G253D thus was separable from its detrimental effects on dendrite growth. We recently identified DCX-R59H as a dominant allele and can now classify DCX-G253D as a second DCX allele that acts dominantly to cause pathology, but does so via a different mechanism. PMID- 30291145 TI - Electrical Impedance Methods in Neuromuscular Assessment: An Overview. AB - Electrical impedance methods have been used as evaluation tools in biological and medical science for well over 100 years. However, only recently have these techniques been applied specifically to the evaluation of conditions affecting nerve and muscle. This specific application, termed electrical impedance myography (EIM), is finding wide application as it can provide a quantitative index of muscle condition that can assist with diagnosis, track disease progression, and assess the beneficial impact of therapy. Using noninvasive surface methods, EIM has been studied in a number of conditions ranging from amyotrophic lateral sclerosis to muscular dystrophy to disuse atrophy. Data support that the technique is sensitive to disease status and can offer the possibility of performing clinical trials with fewer subjects than would otherwise be possible. Recent advances in the field include improved approaches for using EIM as a "virtual biopsy" and the development of combined needle impedance-electromyography technology. PMID- 30291146 TI - Optogenetic Medicine: Synthetic Therapeutic Solutions Precision-Guided by Light. AB - Gene- and cell-based therapies are well recognized as central pillars of next generation medicine, but controllability remains a critical issue for clinical applications. In this context, optogenetics is opening up exciting new opportunities for precision-guided medicine by using illumination with light of appropriate intensity and wavelength as a trigger signal to achieve pinpoint spatiotemporal control of cellular activities, such as transgene expression. In this review, we highlight recent advances in optogenetics, focusing on devices for biomedical applications. We introduce the construction and applications of optogenetic-based biomedical tools to treat neurological diseases, diabetes, heart diseases, and cancer, as well as bioelectronic implants that combine light interfaced electronic devices and optogenetic systems into portable personalized precision bioelectronic medical tools. Optogenetics-based technology promises the capability to achieve traceless, remotely controlled precision dosing of an enormous range of therapeutic outputs. Finally, we discuss the prospects for optogenetic medicine, as well as some emerging challenges. PMID- 30291147 TI - Technobiology's Enabler: The Magnetoelectric Nanoparticle. AB - To enable patient- and disease-specific diagnostic and treatment at the intracellular level in real time, it is imperative to engineer a perfect way to locally stimulate selected individual neurons, navigate and dispense a cargo of biomolecules into damaged cells or image sites with relatively high efficacy and with adequate spatial and temporal resolutions. Significant progress has been made using biotechnology; especially with the development of bioinformatics, there are endless molecular databases to identify biomolecules to target almost any disease-specific biomarker. Conversely, the technobiology approach that exploits advanced engineering to control underlying molecular mechanisms to recover biosystem's energy states at the molecular level as well as at the level of the entire network of cells (i.e., the internet of the human body) is still in its early research stage. The recently developed magnetoelectric nanoparticles (MENPs) provide a tool to enable the unique capabilities of technobiology. Using exemplary studies that could potentially lead to future pinpoint treatment and prevention of cancer, neurodegenerative diseases, and HIV, this article discusses how MENPs could become a vital enabling tool of technobiology. PMID- 30291148 TI - Prostate Stem Cells and Cancer Stem Cells. AB - Stem/progenitor cells play central roles in processes of organogenesis and tissue maintenance, whereas cancer stem cells (CSCs) are thought to drive tumor malignancy. Here, we review recent progress in the identification and analysis of normal prostate stem/progenitor cells as well as putative CSCs in both genetically engineered mouse models as well as in human tissue. We also discuss studies that have investigated the cell type of origin for prostate cancer. In addition, we provide a critical assessment of methodologies used in stem cell analyses and outline directions for future research. PMID- 30291149 TI - Age-Related Hearing Loss. AB - Age-related hearing loss (ARHL) is the most prevalent sensory deficit in the elderly. This progressive hearing impairment leads to social isolation and is also associated with comorbidities, such as frailty, falls, and late-onset depression. Moreover, there is a growing evidence linking it with cognitive decline and increased risk of dementia. Given the large social and welfare burden that results from ARHL, and because ARHL is potentially a modifiable risk factor for dementia, there is an urgent need for therapeutic interventions to ameliorate age-related auditory decline. However, a prerequisite for design of therapies is knowledge of the underlying molecular mechanisms. Currently, our understanding of ARHL is very limited. Here, we review recent findings from research into ARHL from both human and animal studies and discuss future prospects for advances in our understanding of genetic susceptibility, pathology, and potential therapeutic approaches in ARHL. PMID- 30291150 TI - Function and Dysfunction of TMC Channels in Inner Ear Hair Cells. AB - The TMC1 channel was identified as a protein essential for hearing in mouse and human, and recognized as one of a family of eight such proteins in mammals. The TMC family is part of a superfamily of seven branches, which includes the TMEM16s. Vertebrate hair cells express both TMC1 and TMC2. They are located at the tips of stereocilia and are required for hair cell mechanotransduction. TMC1 assembles as a dimer and its similarity to the TMEM16s has enabled a predicted tertiary structure with an ion conduction pore in each subunit of the dimer. Cysteine mutagenesis of the pore supports the role of TMC1 and TMC2 as the core channel proteins of a larger mechanotransduction complex that includes PCDH15 and LHFPL5, and perhaps TMIE, CIB2 and others. PMID- 30291152 TI - "Fit notes" could become part of GP training, says deputy chief medical officer. PMID- 30291151 TI - An interview with Robb Krumlauf. AB - Robb Krumlauf is a developmental biologist who studies the Hox family of transcription factors, aiming to understand how these proteins regulate animal body plans. Robb, who is currently Scientific Director of the Stowers Institute for Medical Research, was recently awarded the 2018 SDB Edwin G. Conklin Award for his extraordinary contributions to the field of developmental biology and for his excellent mentoring skills. We met with Robb at this year's SDB Annual Meeting, where he was presented with the award, to find out more about his research, his career and his thoughts on mentorship. PMID- 30291153 TI - Protective effects of helmets on bicycle-related injuries in elderly individuals. AB - OBJECTIVE: The increasing frequency of bicycle-related injuries is due to the growing elderly population and their increasing physical activity. This study aimed to compare the protective effects of helmets on bicycle-related injuries in elderly individuals compared with those in younger adults. METHODS: Data from the Korean emergency department-based Injury In-depth Surveillance database from eight emergency departments during 2011-2016 were retrospectively analysed. The subjects sustained injuries while riding bicycles. Cases with unknown clinical outcomes were excluded. Covariates included mechanism, place and time of injury. The primary outcome was traumatic brain injury (TBI) incidence, and the secondary outcomes were in-hospital mortality and severe trauma. The effects of helmets on these outcomes were analysed and differences in effects were determined using logistic regression analysis. Subsequently, the differences in the effects of helmets use between age groups were examined by using interaction analysis RESULTS: Of 7181 adults, 1253 were aged >65 years. The injury incidents showed a bimodal pattern with peaks around ages 20 and 50 years. Meanwhile, the helmet wearing rate showed a unimodal pattern with its peak at age 35-40 years; it decreased consistently with age. By multivariate analysis, helmet-wearing was associated with a reduced TBI incidence (OR 0.76; 95% CI 0.57 to 0.99) and severe trauma (OR 0.78; 95% CI 0.65 to 0.93). The effects of helmets increased in elderly individuals (TBI (p=0.022) and severe trauma (p=0.024)). CONCLUSION: The protective effects of helmets on bicycle-related injuries are greater for elderly individuals, thus reducing TBI incidence. PMID- 30291154 TI - Challenges of enforcing cell phone use while driving laws among police: a qualitative study. AB - BACKGROUND: Cell phone use while driving laws do not appear to be heavily enforced in the USA. This study seeks to gain law enforcements' perspective and learn potential barriers to cell phone law enforcement. METHODS: Qualitative interviews (ie, focus groups) were conducted with officers (N=19) from five West Virginia law enforcement agencies. The officers who participated were >18 years of age, sworn into their departments and employed in law enforcement for >1 year. Focus group sessions lasted 45-60 min and followed a standardised, pilot-tested script. These sessions were audio recorded and transcribed. Qualitative content analysis was employed among three researchers to determine themes surrounding enforcement. RESULTS: Four themes emerged including current culture, the legal system, the nature of police work and issues with prevention. Specific barriers to enforcement included cultural norms, lack of perceived support from courts/judges, different laws between states, the need for a general distracted driving law, unclear legislation, officers' habits and perceived risk, wanting to maintain a positive relationship with the public, not being able to see the driver (impediments of vehicle design, time of day), phones having multiple functions and not knowing what drivers are actually doing, risk of crashing during traffic stops and lack of resources. Prevention activities were debated, and most felt that technological advancements implemented by cell phone manufacturers may deter use. CONCLUSIONS: Numerous barriers to cell phone law enforcement exist. Legislation could be amended to facilitate enforcement. Prevention opportunities exist to deter cell phone use while driving. PMID- 30291155 TI - Injury prevention class exercise: three-pronged list making. AB - It is difficult to find classroom exercises that have been specifically designed for injury prevention students. The suggested list-making classroom exercise forces students to recognise and devise many policy and programmatic options over and above the ones that normally spring to mind. Most important, it helps give students a better understanding of what is meant by, and the potential usefulness of, the public health approach to injury prevention. PMID- 30291156 TI - A solution to Nature's haemoglobin knockout: a plasma-accessible carbonic anhydrase catalyses CO2 excretion in Antarctic icefish gills. AB - In all vertebrates studied to date, CO2 excretion depends on the enzyme carbonic anhydrase (CA) that catalyses the rapid conversion of HCO3 - to CO2 at the gas exchange organs. The largest pool of CA is present within red blood cells (RBCs) and, in some vertebrates, plasma-accessible CA (paCA) isoforms participate in CO2 excretion. However, teleost fishes typically do not have paCA at the gills and CO2 excretion is reliant entirely on RBC CA - a strategy that is not possible in icefishes. As the result of a natural knockout, Antarctic icefishes (Channichthyidae) are the only known vertebrates that do not express haemoglobin (Hb) as adults, and largely lack RBCs in the circulation (haematocrit <1%). Previous work has indicated the presence of high levels of membrane-bound CA activity in the gills of icefishes, but without determining its cellular orientation. Thus, we hypothesised that icefishes express a membrane-bound CA isoform at the gill that is accessible to the blood plasma. The CA distribution was compared in the gills of two closely related notothenioid species, one with Hb and RBCs (Notothenia rossii) and one without (Champsocephalus gunnari). Molecular, biochemical and immunohistochemical markers indicate high levels of a Ca4 isoform in the gills of the icefish (but not the red-blooded N. rossii), in a plasma-accessible location that is consistent with a role in CO2 excretion. Thus, in the absence of RBC CA, the icefish gill could exclusively provide the catalytic activity necessary for CO2 excretion - a pathway that is unlike that of any other vertebrate. PMID- 30291157 TI - Hydrodynamics of linear acceleration in bluegill sunfish, Lepomis macrochirus. AB - In their natural habitat, fish rarely swim steadily. Instead they frequently accelerate and decelerate. Relatively little is known about how fish produce extra force for acceleration in routine swimming behavior. In this study, we examined the flow around bluegill sunfish Lepomis macrochirus during steady swimming and during forward acceleration, starting at a range of initial swimming speeds. We found that bluegill produce vortices with higher circulation during acceleration, indicating a higher force per tail beat, but they do not substantially redirect the force. We quantified the flow patterns using high speed video and particle image velocimetry and measured acceleration with small inertial measurement units attached to each fish. Even in steady tail beats, the fish accelerates slightly during each tail beat, and the magnitude of the acceleration varies. In steady tail beats, however, a high acceleration is followed by a lower acceleration or a deceleration, so that the swimming speed is maintained; in unsteady tail beats, the fish maintains the acceleration over several tail beats, so that the swimming speed increases. We can thus compare the wake and kinematics during single steady and unsteady tail beats that have the same peak acceleration. During unsteady tail beats when the fish accelerates forward for several tail beats, the wake vortex forces are much higher than those at the same acceleration during single tail beats in steady swimming. The fish also undulates its body at higher amplitude and frequency during unsteady tail beats. These kinematic changes likely increase the fluid dynamic added mass of the body, increasing the forces required to sustain acceleration over several tail beats. The high amplitude and high frequency movements are also likely required to generate the higher forces needed for acceleration. Thus, it appears that bluegill sunfish face a trade-off during acceleration: the body movements required for acceleration also make it harder to accelerate. PMID- 30291158 TI - Should I stay or should I go? The settlement-inducing protein complex guides barnacle settlement decisions. AB - Reproduction in barnacles relies on chemical cues that guide their gregarious settlement. These cues have been pinned down to several sources of settlement pheromones, one of which is a protein termed settlement-inducing protein complex (SIPC), a large glycoprotein acting as a pheromone to induce larval settlement and as an adhesive in surface exploration by the cyprids. Settlement assays in laboratory conditions with Amphibalanus (=Balanus) amphitrite cyprids in the presence of SIPC showed that cyprids exhibit settlement preference behaviour at lower concentrations of SIPC [half maximal effective concentration (EC50)=3.73 nmol l-1] and settlement avoidance behaviour at higher concentrations (EC50=101 nmol l-1). By using truncated fragments of SIPC in settlement assays, we identify that domains at the N-terminus of SIPC transduce settlement preference cues that mask the settlement avoidance cues transduced by domains at its C-terminus. Removing the N-terminal 600 amino acids from SIPC resulted in truncated fragments that transduced only settlement avoidance cues to the cyprids. From the sexual reproduction point of view, this bimodal response of barnacles to SIPC suggests that barnacles will settle gregariously when conspecific cues are sparse but will not settle if conspecific cues inform of overcrowding that will increase reproductive competition and diminish their reproductive chances. PMID- 30291159 TI - Hawkmoth flight in the unsteady wakes of flowers. AB - Flying animals maneuver and hover through environments where wind gusts and flower wakes produce unsteady flow. Although both flight maneuvers and aerodynamic mechanisms have been studied independently, little is known about how these interact in an environment where flow is already unsteady. Moths forage from flowers by hovering in the flower's wake. We investigated hawkmoths tracking a 3D-printed robotic flower in a wind tunnel. We visualized the flow in the wake and around the wings and compared tracking performance with previous experiments in a still-air flight chamber. As in still air, moths flying in the flower wake exhibit near-perfect tracking at the low frequencies at which natural flowers move. However, tracking in the flower wake results in a larger overshoot between 2 and 5 Hz. System identification of flower tracking reveals that moths also display reduced-order dynamics in wind compared with still air. Smoke visualization of the flower wake shows that the dominant vortex shedding corresponds to the same frequency band as the increased overshoot. Despite these large effects on tracking dynamics in wind, the leading edge vortex (LEV) remains bound to the wing throughout the wingstroke and does not burst. The LEV also maintains the same qualitative structure seen in steady air. Persistence of a stable LEV during decreased flower tracking demonstrates the interplay between hovering and maneuvering. PMID- 30291160 TI - Substantial heat tolerance acclimation capacity in tropical thermophilic snails, but to what benefit? AB - The theory for thermal acclimation of ectotherms suggests that (1) heat tolerance is traded off for thermal acclimation in thermophilic species and that (2) plasticity is constrained in tropically distributed ectotherms, which commonly experience relatively thermally stable environments. We observed substantial heat tolerance plasticity in a test of this theory using tropical, thermophilic marine intertidal snails that inhabit extremely hot and highly variable thermal environments. The implication of these results is that plasticity selection is largely driven by habitat temperature conditions irrespective of basal heat tolerance or latitude. However, heat tolerance of field-fresh snails was comparable with that of laboratory warm-acclimated snails, suggesting that snails in the field may often be unable to improve heat hardening with further environmental warming. These findings suggest that field referencing is crucial to using laboratory-measured acclimation capacity when inferring climate warming vulnerability in ectotherms, and overall they question how well current thermal biology theory predicts the outcomes of global change in intertidal environments. PMID- 30291162 TI - Inhibition of cell fate repressors secures the differentiation of the touch receptor neurons of Caenorhabditis elegans. AB - Terminal differentiation generates the specialized features and functions that allow postmitotic cells to acquire their distinguishing characteristics. This process is thought to be controlled by transcription factors called 'terminal selectors' that directly activate a set of downstream effector genes. In Caenorhabditis elegans, the differentiation of both the mechanosensory touch receptor neurons (TRNs) and the multidendritic nociceptor FLP neurons uses the terminal selectors UNC-86 and MEC-3. The FLP neurons fail to activate TRN genes, however, because a complex of two transcriptional repressors (EGL-44/EGL-46) prevents their expression. Here, we show that the ZEB family transcriptional factor ZAG-1 promotes TRN differentiation not by activating TRN genes but by preventing the expression of EGL-44/EGL-46. As EGL-44/EGL-46 also inhibits the production of ZAG-1, these proteins form a bistable, negative-feedback loop that regulates the choice between the two neuronal fates. PMID- 30291161 TI - Kinetics of adult hematopoietic stem cell differentiation in vivo. AB - Adult hematopoiesis has been studied in terms of progenitor differentiation potentials, whereas its kinetics in vivo is poorly understood. We combined inducible lineage tracing of endogenous adult hematopoietic stem cells (HSCs) with flow cytometry and single-cell RNA sequencing to characterize early steps of hematopoietic differentiation in the steady-state. Labeled cells, comprising primarily long-term HSCs and some short-term HSCs, produced megakaryocytic lineage progeny within 1 wk in a process that required only two to three cell divisions. Erythroid and myeloid progeny emerged simultaneously by 2 wk and included a progenitor population with expression features of both lineages. Myeloid progenitors at this stage showed diversification into granulocytic, monocytic, and dendritic cell types, and rare intermediate cell states could be detected. In contrast, lymphoid differentiation was virtually absent within the first 3 wk of tracing. These results show that continuous differentiation of HSCs rapidly produces major hematopoietic lineages and cell types and reveal fundamental kinetic differences between megakaryocytic, erythroid, myeloid, and lymphoid differentiation. PMID- 30291163 TI - Fam46a regulates BMP-dependent pre-placodal ectoderm differentiation in Xenopus. AB - The pre-placodal ectoderm (PPE) is a specialized ectodermal region which gives rise to the sensory organs and other systems. The PPE is induced from the neural plate border during neurulation, but the molecular mechanism of PPE formation is not fully understood. In this study, we examined the role of a newly identified PPE gene, Fam46a, during embryogenesis. Fam46a contains a nucleoside triphosphate transferase domain, but its function in early development was previously unclear. We show that Fam46a is expressed in the PPE in Xenopus embryos, and Fam46a knockdown induces abnormalities in the eye formation and the body color. At the neurula stage, Fam46a upregulates the expression of PPE genes and inhibits neural crest formation. We also show that Fam46a physically interacts with Smad1/Smad4 and positively regulates BMP signaling. From these results, we conclude that Fam46a is required for PPE formation via the positive regulation of BMP signaling. Our study provides a new mechanism of ectodermal patterning via cell autonomous regulation of BMP signaling in the PPE.

PMID- 30291164 TI - Distinct temporal requirements for Sonic hedgehog signaling in development of the tuberal hypothalamus. AB - Sonic hedgehog (Shh) plays well characterized roles in brain and spinal cord development, but its functions in the hypothalamus have been more difficult to elucidate owing to the complex neuroanatomy of this brain area. Here, we use fate mapping and conditional deletion models in mice to define requirements for dynamic Shh activity at distinct developmental stages in the tuberal hypothalamus, a brain region with important homeostatic functions. At early time points, Shh signaling regulates dorsoventral patterning, neurogenesis and the size of the ventral midline. Fate-mapping experiments demonstrate that Shh expressing and -responsive progenitors contribute to distinct neuronal subtypes, accounting for some of the cellular heterogeneity in tuberal hypothalamic nuclei. Conditional deletion of the hedgehog transducer smoothened (Smo), after dorsoventral patterning has been established, reveals that Shh signaling is necessary to maintain proliferation and progenitor identity during peak periods of hypothalamic neurogenesis. We also find that mosaic disruption of Smo causes a non-cell autonomous gain in Shh signaling activity in neighboring wild-type cells, suggesting a mechanism for the pathogenesis of hypothalamic hamartomas, benign tumors that form during hypothalamic development. PMID- 30291166 TI - IL-4 and IL-13 Guide Early Thymic Progenitors To Mature toward Dendritic Cells. AB - Recently we reported that IL-4 and IL-13 signaling in murine early thymic progenitors (ETPs) expressing the heteroreceptor (HR) comprising IL-4 receptor alpha (IL-4Ralpha) and IL-13 receptor alpha 1 (IL-13Ralpha1) activate STAT6 and inhibit ETP maturation potential toward T cells. In this study, we asked whether IL-4 and IL-13 signaling through the HR mobilizes other STAT molecules to shape ETP fate decision. The findings indicate that HR+ ETPs undergoing cytokine signaling display increased STAT1, but not STAT3, phosphorylation in addition to STAT6 activation. In parallel, the ETPs had a STAT1-dependent heightened expression of IRF-8, a transcription factor essential for development of CD8alpha+ dendritic cells (DCs). Interestingly, STAT1 phosphorylation and IRF-8 upregulation, which are independent of STAT6 activation, guided ETP maturation toward myeloid cells with a CD8alpha+ DC phenotype. Furthermore, these CD8alpha+ DCs display a thymic resident phenotype, as they did not express SIRPalpha, a molecule presumed to be involved in cell migration. These findings suggest that IL-4 and IL-13 cytokine-induced HR signaling provides a double-edged sword that simultaneously blocks T cell lineage potential but advances myeloid maturation that could impact T cell selection and central tolerance. PMID- 30291168 TI - Antecedents of Obesity Among Children Born Extremely Preterm. AB - BACKGROUND: Childhood obesity is a pervasive public health problem with risk factors such as maternal prepregnancy BMI and rapid infant weight gain. Although catch-up weight gain promotes more favorable neurodevelopment among infants born preterm, it is not clear whether faster weight gain early in life, or other correlates of preterm birth, are associated with later obesity in this population. METHODS: We used prospective data from the multicenter, observational Extremely Low Gestational Age Newborn Study. Among 1506 eligible individuals in the initial cohort, 1198 were eligible for follow-up at 10 years of age. We examined BMI in 871 children (58% of the cohort; 74% of survivors) and analyzed relationships between antecedents and overweight or obesity at 10 years of age. A time-oriented approach to multinomial multivariable regression enabled us to calculate odds of overweight and obesity associated with pre- and postnatal antecedents. RESULTS: Prepregnancy maternal BMI >=25 and top quartile infant weight gain in the first year were associated with increased risk of both overweight and obesity at 10 years of age. Single marital status was a risk factor for later child obesity and exposure to tobacco smoke was a risk factor for later child overweight. CONCLUSIONS: The risk profiles for overweight and obesity at 10 years of age among children born extremely preterm appear to be similar to the risk profiles of overweight and obesity among children born at term.

PMID- 30291167 TI - Helminth-Induced Production of TGF-beta and Suppression of Graft-versus-Host Disease Is Dependent on IL-4 Production by Host Cells. AB - Helminths stimulate the secretion of Th2 cytokines, like IL-4, and suppress lethal graft-versus-host disease (GVHD) after bone marrow transplantation. This suppression depends on the production of immune-modulatory TGF-beta and is associated with TGF-beta-dependent in vivo expansion of Foxp3+ regulatory T cells (Treg). In vivo expansion of Tregs is under investigation for its potential as a therapy for GVHD. Nonetheless, the mechanism of induced and TGF-beta-dependent in vivo expansion of Tregs, in a Th2 polarized environment after helminth infection, is unknown. In this study, we show that helminth-induced IL-4 production by host cells is critical to the induction and maintenance of TGF-beta secretion, TGF beta-dependent expansion of Foxp3+ Tregs, and the suppression of GVHD. In mice with GVHD, the expanding donor Tregs express the Th2-driving transcription factor, GATA3, which is required for helminth-induced production of IL-4 and TGF beta. In contrast, TGF-beta is not necessary for GATA3 expression by Foxp3+ Tregs or by Foxp3- CD4 T cells. Various cell types of innate or adaptive immune compartments produce high quantities of IL-4 after helminth infection. As a result, IL-4-mediated suppression of GVHD does not require invariant NKT cells of the host, a cell type known to produce IL-4 and suppress GVHD in other models. Thus, TGF-beta generation, in a manner dependent on IL-4 secretion by host cells and GATA3 expression, constitutes a critical effector arm of helminthic immune modulation that promotes the in vivo expansion of Tregs and suppresses GVHD. PMID- 30291170 TI - The structure and evolution of eukaryotic chaperonin-containing TCP-1 and its mechanism that folds actin into a protein spring. AB - Actin is folded to its native state in eukaryotic cytosol by the sequential allosteric mechanism of the chaperonin-containing TCP-1 (CCT). The CCT machine is a double-ring ATPase built from eight related subunits, CCT1-CCT8. Non-native actin interacts with specific subunits and is annealed slowly through sequential binding and hydrolysis of ATP around and across the ring system. CCT releases a folded but soft ATP-G-actin monomer which is trapped 80 kJ/mol uphill on the folding energy surface by its ATP-Mg2+/Ca2+ clasp. The energy landscape can be re explored in the actin filament, F-actin, because ATP hydrolysis produces dehydrated and more compact ADP-actin monomers which, upon application of force and strain, are opened and closed like the elements of a spring. Actin-based myosin motor systems underpin a multitude of force generation processes in cells and muscles. We propose that the water surface of F-actin acts as a low-binding energy, directional waveguide which is recognized specifically by the myosin lever-arm domain before the system engages to form the tight-binding actomyosin complex. Such a water-mediated recognition process between actin and myosin would enable symmetry breaking through fast, low energy initial binding events. The origin of chaperonins and the subsequent emergence of the CCT-actin system in LECA (last eukaryotic common ancestor) point to the critical role of CCT in facilitating phagocytosis during early eukaryotic evolution and the transition from the bacterial world. The coupling of CCT-folding fluxes to the cell cycle, cell size control networks and cancer are discussed together with directions for further research. PMID- 30291171 TI - New tools for evaluating protein tyrosine sulfation and carbohydrate sulfation. AB - Sulfation is a common modification of extracelluar glycans and tyrosine residues on proteins, which is important in many signalling pathways and interactions. Existing methods for studying sulfotransferases, the enzymes that catalyse sulfation, are cumbersome and low-throughput. Recent studies published in the Biochemical Journal have repurposed established biochemical assays from the kinase field and applied them to the characterisation of sulfotransferases. Biochemical screening of a library of kinase inhibitors revealed that compounds that target RAF kinases may also be repurposed to inhibit sulfotransferases. Together with the available structures of sulfotransferases, these studies open the door to the development of chemical tools to probe the biological functions of these important enzymes. PMID- 30291172 TI - Physicochemical Solubility of and Biological Sensitivity to Long-Chain Alcohols Determine the Cutoff Chain Length in Biological Activity. AB - The cutoff phenomenon associated with the effectiveness of long-chain alcohols in the induction of anesthesia is also observed for various antimicrobial activities, although the mechanism has remained unknown for over eight decades. The minimum inhibitory concentrations at 25 degrees C for budding yeast growth exponentially decreased with increasing chain length of n-alcohols (C2-C12), whereas alcohols >=C13 lost the inhibitory effect. Thus, growth inhibition by n alcohols obeys the Meyer-Overton correlation up to C12 and exhibits a cutoff phenomenon. The densities of n-alcohols are low, and the melting point and hydrophobicity increase with chain length. C13 and C14 inhibited yeast growth at 39.8 degrees C, above their melting points. Alcohols <=C14 inhibited thermophilic bacterial growth at 50 degrees C, whereas C16 inhibited it at 67.5 degrees C, above their melting points. Thus, the high melting points of long-chain alcohols contribute to the cutoff phenomenon. C14 did not effectively inhibit yeast growth in a static culture at 39.8 degrees C, in contrast to a shaking culture, in which the low density-dependent concentration gradient was eliminated. The duration of the transient growth inhibition of yeast by C12 was prolonged by sonication, which prevented hydrophobic aggregation. Therefore, a nonuniform distribution owing to low density and high hydrophobicity contributes to the cutoff. C14 inhibited the growth at 25 degrees C of the pdr1,3,5 mutant, defective in multidrug efflux pumps, whereas C12 did not inhibit the growth of yeast overexpressing PDR5, indicating that the sensitivity to long-chain alcohols contributed to the cutoff. A balance between the physicochemical solubility of and the biological sensitivity to long-chain alcohols determines the cutoff chain length. PMID- 30291173 TI - Safinamide Modulates Striatal Glutamatergic Signaling in a Rat Model of Levodopa Induced Dyskinesia. AB - Safinamide (Xadago) is a novel dual-mechanism drug that has been approved in the European Union and United States as add-on treatment to levodopa in Parkinson's disease therapy. In addition to its selective and reversible monoamine oxidase B inhibition, safinamide through use-dependent sodium channel blockade reduces overactive glutamatergic transmission in basal ganglia, which is believed to contribute to motor symptoms and complications including levodopa-induced dyskinesia (LID). The present study investigated the effects of safinamide on the development of LID in 6-hydroxydopamine (6-OHDA)-lesioned rats, evaluating behavioral, molecular, and neurochemical parameters associated with LID appearance. 6-OHDA-lesioned rats were treated with saline, levodopa (6 mg/kg), or levodopa plus safinamide (15 mg/kg) for 21 days. Abnormal involuntary movements, motor performance, molecular composition of the striatal glutamatergic synapse, glutamate, and GABA release were analyzed. In the striatum, safinamide prevented the rearrangement of the subunit composition of N-methyl-d-aspartate receptors and the levodopa-induced increase of glutamate release associated with dyskinesia without affecting the levodopa-stimulated motor performance and dyskinesia. Overall, these findings suggest that the striatal glutamate-modulating component of safinamide's activity may contribute to its clinical effects, where its long term use as levodopa add-on therapy significantly improves motor function and "on" time without troublesome dyskinesia. PMID- 30291174 TI - Celecoxib Treatment Improves Neurologic Deficit and Reduces Selective Neuronal Loss and Glial Response in Rats after Transient Middle Cerebral Artery Occlusion. AB - Areas of selective neuronal loss (SNL) represent the first morphologic signs of damage in the penumbra region and are considered putative targets for ischemic stroke therapy. We performed a novel assessment of measuring the effects of the anti-inflammatory agent celecoxib by analyzing simultaneously the different neural populations (neurons, astrocytes, and microglia cells) in SNL and non-SNL areas. Rats were subjected to 1 hour of middle cerebral artery occlusion (MCAO) and treated with celecoxib 1 and 24 hours after ischemia. Infarct volume measurements and triple immunostaining of neurons (neuronal nuclear antigen), microglia (ionized calcium-binding adaptor molecule 1), and astroglia were performed after 12 and 48 hours of reperfusion. Motor response was tested by standard behavioral assays at 3, 12, 24, and 48 hours. Confocal analysis revealed that the percentage of SNL areas, microglia densities, and glial activation increased at 48 hours of reperfusion. Celecoxib treatment improved the neurologic deficit, reduced the infarct volume by 50% after 48 hours of reperfusion, and resulted in a reduced percentage of SNL areas and microglia and astroglia reactivity after 48 hours of reperfusion. This study proves, for the first time, that celecoxib presents postischemic neuroprotective effects in a transient MCAO model, prevents or delays the presence of SNL areas, and reduces glial activation.

PMID- 30291175 TI - Engineering Artificial MicroRNAs for Multiplex Gene Silencing and Simplified Transgenic Screen. AB - Artificial microRNA (amiRNA) technology offers reversible and flexible gene inactivation and complements genome-editing technologies. However, obtaining transgenic plants with maximal gene silencing remains a major technical challenge in current amiRNA applications. Here, we incorporated an empirically determined feature of effective amiRNAs to the amiRNA design and in silico generated a database containing 533,429 gene-specific amiRNAs for silencing 27,136 genes in Arabidopsis (Arabidopsis thaliana), with a genome coverage of 98.87%. In both single-gene and multiple-gene silencing, we observed an overall improvement in performance by amiRNAs designed using our strategy in Arabidopsis protoplasts and transgenic plants. In addition, the endogenous tRNA-processing system was used to generate multiple amiRNAs from tRNA-pre-amiRNA tandem repeats for multiplex gene silencing. An intronic amiRNA-producing fluorescent reporter was explored as a visual screening strategy for transgenic Arabidopsis and rice (Oryza sativa) plants with maximal whole-plant or cell type-specific gene silencing. These improvements enable the amiRNA technology to be a functional gene knockout tool for basic and applied plant research.

PMID- 30291179 TI - Framing the challenges of artificial intelligence in medicine. PMID- 30291180 TI - Application of electronic trigger tools to identify targets for improving diagnostic safety. AB - Progress in reducing diagnostic errors remains slow partly due to poorly defined methods to identify errors, high-risk situations, and adverse events. Electronic trigger (e-trigger) tools, which mine vast amounts of patient data to identify signals indicative of a likely error or adverse event, offer a promising method to efficiently identify errors. The increasing amounts of longitudinal electronic data and maturing data warehousing techniques and infrastructure offer an unprecedented opportunity to implement new types of e-trigger tools that use algorithms to identify risks and events related to the diagnostic process. We present a knowledge discovery framework, the Safer Dx Trigger Tools Framework, that enables health systems to develop and implement e-trigger tools to identify and measure diagnostic errors using comprehensive electronic health record (EHR) data. Safer Dx e-trigger tools detect potential diagnostic events, allowing health systems to monitor event rates, study contributory factors and identify targets for improving diagnostic safety. In addition to promoting organisational learning, some e-triggers can monitor data prospectively and help identify patients at high-risk for a future adverse event, enabling clinicians, patients or safety personnel to take preventive actions proactively. Successful application of electronic algorithms requires health systems to invest in clinical informaticists, information technology professionals, patient safety professionals and clinicians, all of who work closely together to overcome development and implementation challenges. We outline key future research, including advances in natural language processing and machine learning, needed to improve effectiveness of e-triggers. Integrating diagnostic safety e-triggers in institutional patient safety strategies can accelerate progress in reducing preventable harm from diagnostic errors. PMID- 30291181 TI - Virtual outpatient clinic as an alternative to an actual clinic visit after surgical discharge: a randomised controlled trial. AB - BACKGROUND: It is standard practice to review all patients following discharge at a follow-up clinic but demands on all health services outweigh resources and unnecessary review appointments may delay or deny access to patients with greater needs. AIMS: This randomised trial aimed to establish whether a virtual outpatient clinic (VOPC) was an acceptable alternative to an actual outpatient clinic (OPC) attendance for a broad range of general surgical patients following a hospital admission. PATIENTS AND METHODS: All patients admitted under one general surgical service over the study period were assessed. If eligible for inclusion the rationale, randomisation and follow-up methods were explained, consent was sought and patients randomised to receive either a VOPC or an OPC appointment. RESULTS: Two-hundred and nine patients consented to study inclusion, of which 98/107 (91.6%) in the VOPC group and 83/102 (81.4%) in the OPC group were successfully contacted. Only 6 patients in the OPC group and 10 in the VOPC group reported ongoing issues. A further follow-up indicated 78 of 82 (95%) VOPC patients were very happy with their overall experience compared with 34/61 (56%) in the actual OPC group (p<0.001). A significant proportion of both cohorts-68/82 (83%) in VOPC group and 41/61 (67%) in OPC group (p = 0.029)-preferred a VOPC appointment as their future follow-up of choice. CONCLUSIONS: The majority of patients discharged from a surgical service could be better followed up by a virtual clinic with a significant proportion of patients reporting a preference for and a greater satisfaction with such a service. PMID- 30291182 TI - Clinical correlates of quantitative EEG in Parkinson disease: A systematic review. AB - OBJECTIVE: To assess the relevance of quantitative EEG (qEEG) measures as outcomes of disease severity and progression in Parkinson disease (PD). METHODS: Main databases were systematically searched (January 2018) for studies of sufficient methodologic quality that examined correlations between clinical symptoms of idiopathic PD and cortical (surface) qEEG metrics. RESULTS: Thirty six out of 605 identified studied were included. Results were classified into 4 domains: cognition (23 studies), motor function (13 studies), responsiveness to interventions (7 studies), and other (10 studies). In cross-sectional studies, EEG slowing correlated with global cognitive impairment and with diffuse deterioration in other domains. In longitudinal studies, decreased dominant frequency and increased theta power, reflecting EEG slowing, were biomarkers of cognitive deterioration at an individual level. Results on motor dysfunction and treatment yielded contrasting findings. Studies on functional connectivity at an individual level and longitudinal studies on other domains or on connectivity measures were lacking. CONCLUSION: qEEG measures reflecting EEG slowing, particularly decreased dominant frequency and increased theta power, correlate with cognitive impairment and predict future cognitive deterioration. qEEG could provide reliable and widely available biomarkers for nonmotor disease severity and progression in PD, potentially promoting early diagnosis of nonmotor symptoms and an objective monitoring of progression. More studies are needed to clarify the role of functional connectivity and network analyses. PMID- 30291183 TI - CSF sAPPbeta, YKL-40, and NfL along the ALS-FTD spectrum. AB - OBJECTIVE: To investigate the clinical utility of 3 CSF biomarkers along the clinical spectrum of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). METHODS: We analyzed 3 CSF biomarkers: the soluble beta-fragment of amyloid precursor protein (sAPPbeta), YKL-40, and neurofilament light (NfL) in FTD (n = 86), ALS (n = 38), and a group of age-matched cognitively normal controls (n = 49). Participants with FTD with a CSF profile of Alzheimer disease were excluded. We compared cross-sectional biomarker levels between groups, studied their correlation with cognitive and functional scales (global cognitive z score, frontotemporal lobar degeneration Clinical Dementia Rating, revised ALS Functional Rating Scale, and ALS progression rate), survival, and cortical thickness. RESULTS: We found increased levels of YKL-40 and decreased levels of sAPPbeta in both FTD and ALS groups compared to controls. The lowest sAPPbeta levels and sAPPbeta/YKL-40 ratio were found in the FTD group. In FTD, sAPPbeta and the sAPPbeta/YKL-40 ratio correlated with the disease severity. In the whole ALS-FTD spectrum, NfL levels and the NfL:sAPPbeta ratio correlated with global cognitive performance (r = -0.41, p < 0.001 and r = -0.44, p < 0.001, respectively). In the ALS group, YKL-40 correlated with disease progression rate (r = 0.51, p = 0.001) and was independently associated with shorter survival. In both FTD and ALS groups, the sAPPbeta/YKL-40 ratio showed a positive correlation with cortical thickness in frontotemporal regions. CONCLUSIONS: sAPPbeta, YKL-40, and NfL could represent valuable tools for the staging and prognosis of patients within the ALS-FTD clinical spectrum. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that CSF levels of sAPPbeta, YKL-40, and NfL are useful to assess frontotemporal neurodegeneration and the progression rate in the ALS-FTD continuum. PMID- 30291184 TI - Evidence of mild founder LMOD3 mutations causing nemaline myopathy 10 in Germany and Austria. AB - OBJECTIVE: To expand the clinical and genetic spectrum of nemaline myopathy 10 by a series of Austrian and German patients with a milder disease course and missense mutations in LMOD3. METHODS: We characterized the clinical features and the genetic status of 4 unrelated adolescent or adult patients with nemaline myopathy. RESULTS: The 4 patients showed a relatively mild disease course. They all have survived into adulthood, 3 of 4 have remained ambulatory, and all showed marked facial weakness. Muscle biopsy specimens gave evidence of nemaline bodies. All patients were unrelated but originated from Austria (Tyrol and Upper Austria) and Southern Germany (Bavaria). All patients carried the missense variant c.1648C>T, p.(Leu550Phe) in the LMOD3 gene, either on both alleles or in trans with another missense variant (c.1004A>G, p.Gln335Arg). Both variants were not reported previously. CONCLUSIONS: In 2014, a severe form of congenital nemaline myopathy caused by disrupting mutations in LMOD3 was identified and denoted as NEM10. Unlike the previously reported patients, who had a severe clinical picture with a substantial risk of early death, our patients showed a relatively mild disease course. As the missense variant c.1648C>T is located further downstream compared to all previously published LMOD3 mutations, it might be associated with higher protein expression compared to the reported loss-of-function mutations. The apparent clusters of 2 mild mutations in Germany and Austria in 4 unrelated families may be explained by a founder effect. PMID- 30291185 TI - Congenital myasthenic syndromes in adult neurology clinic: A long road to diagnosis and therapy. AB - OBJECTIVE: To investigate the diagnostic challenges of congenital myasthenic syndromes (CMS) in adult neuromuscular practice. METHODS: We searched the Mayo Clinic database for patients with CMS diagnosed in adulthood in the neuromuscular clinic between 2000 and 2016. Clinical, laboratory, and electrodiagnostic data were reviewed. RESULTS: We identified 34 patients with CMS, 30 of whom had a molecular diagnosis (14 DOK7, 6 RAPSN, 2 LRP4, 2 COLQ, 2 slow-channel syndrome, 1 primary acetylcholine receptor deficiency, 1 AGRN, 1 GFPT1, and 1 SCN4A). Ophthalmoparesis was often mild and present in 13 patients. Predominant limb girdle weakness occurred in 19 patients. Two patients had only ptosis. Age at onset ranged from birth to 39 years (median 5 years). The median time from onset to diagnosis was 26 years (range 4-56 years). Thirteen patients had affected family members. Fatigable weakness was present when examined. Creatine kinase was elevated in 4 of 23 patients (range 1.2-4.2 times the upper limit of normal). Repetitive nerve stimulation revealed a decrement in 30 patients. Thirty-two patients were previously misdiagnosed with seronegative myasthenia gravis (n = 16), muscle diseases (n = 15), weakness of undetermined cause (n = 8), and others (n = 4). Fifteen patients received immunotherapy or thymectomy without benefits. Fourteen of the 25 patients receiving pyridostigmine did not improve or worsen. CONCLUSION: Misdiagnosis occurred in 94% of the adult patients with CMS and causes a median diagnostic delay of nearly 3 decades from symptom onset. Seronegative myasthenia gravis and muscle diseases were the 2 most common misdiagnoses, which led to treatment delay and unnecessary exposure to immunotherapy, thymectomy, or muscle biopsy. PMID- 30291186 TI - Middle cerebral artery geometric features are associated with plaque distribution and stroke. AB - OBJECTIVE: We aimed to investigate the geometric features of the middle cerebral artery (MCA) and their relevance to plaque distribution and ischemic stroke. METHODS: We reviewed our institutional vessel wall imaging database. Patients with symptomatic MCA atherosclerosis, asymptomatic MCA atherosclerosis, or without MCA atherosclerosis were included. The MCA geometric features, including M1 segment shape and M1 curve orientation, were defined on magnetic resonance angiography. Plaque distribution and other plaque parameters were identified on vessel wall imaging. The association among MCA geometric features, plaque distribution, and ischemic stroke were analyzed. RESULTS: A total of 977 MCAs were analyzed (87 atherosclerotic symptomatic MCAs, 459 atherosclerotic asymptomatic MCAs, and 431 plaque-free MCAs). Overall, curved M1 segments were the predominant shape across all groups. In 91.1% of curved atherosclerotic MCAs, the plaque involved the inner wall of the curve. Plaque not involving the inner wall was shorter (p < 0.0001) and thinner (p = 0.005) compared to plaque involving the inner wall. Inferior plaque was observed in 39.9% of inferior oriented M1 curves compared to 21.7% in non-inferior-oriented M1 curves (p < 0.0001). The absence of an inferior-oriented M1 curve (odds ratio 0.45, 95% confidence interval 0.27-0.77) and presence of superior plaque (odds ratio 2.67, 95% confidence interval 1.52-4.67) were independently associated with stroke after adjusting for plaque length and thickness, degree of stenosis, and remodeling ratio. CONCLUSIONS: MCA geometric features are associated with plaque distribution and stroke. Our findings provide insight into the vascular pathophysiology of MCA atherosclerosis. PMID- 30291187 TI - Outcomes after ischemic stroke caused by intracranial atherosclerosis vs dissection. AB - OBJECTIVE: To compare the outcomes between patients with nontraumatic intracranial arterial dissection (ICAD) and intracranial atherosclerotic stenosis (ICAS) using high-resolution MRI (HR-MRI). METHODS: We conducted a prospective study using HR-MRI in patients with acute symptomatic cerebrovascular disease due to intracranial occlusive disease and no dissection on luminal images. Patients were followed-up for 27.9 +/- 19.3 months. We compared the functional outcome, recurrence, and changes in vascular status between patients with ICAD (dissection and no plaque on HR-MRI) and ICAS (atherosclerosis plaque on HR-MRI). RESULTS: We included 312 patients (mean age, 59.0 +/- 14.2 years; men, 58.3%), of whom 113 had ICAD and 199 had ICAS. The functional outcome (as measured by modified Rankin Scale score) on the 90th day after symptom onset was not different between the groups, after adjusted for other factors (p = 0.095). However, recurrent ischemic cerebrovascular disease on the relevant vascular territory was lower in the ICAD group (7 patients, 6.2%) than in the ICAS group (37 patients, 18.6%). ICAD was a significant independent determinant of disease recurrence (hazard ratio, 0.43; 95% confidence interval, 0.19-0.98). Improvement in vascular stenosis on follow up vascular studies was more frequently observed in ICAD (50.7%) than in ICAS (11.6%). ICAD was an independent determinant of vascular improvement (odds ratio, 7.94; 95% confidence interval, 3.32-19.01). CONCLUSION: Considering the high prevalence of ICAD in the patients with presumed ICAS and the differential outcomes between ICAD and ICAS, HR-MRI may be a useful diagnostic tool in this population. PMID- 30291189 TI - Glucose metabolism mediates disease tolerance in cerebral malaria. AB - Sickness behaviors are a conserved set of stereotypic responses to inflammatory diseases. We recently demonstrated that interfering with inflammation-induced anorexia led to metabolic changes that had profound effects on survival of acute inflammatory conditions. We found that different inflammatory states needed to be coordinated with corresponding metabolic programs to actuate tissue-protective mechanisms. Survival of viral inflammation required intact glucose utilization pathways, whereas survival of bacterial inflammation required alternative fuel substrates and ketogenic programs. We thus hypothesized that organismal metabolism would be important in other classes of infectious inflammation and sought to understand its role in the prototypic parasitic disease malaria. Utilizing the cerebral malaria model, Plasmodium berghei ANKA (PbA) infection in C57BL/6J male mice, we unexpectedly found that inhibition of glycolysis using 2 deoxy glucose (2DG) conferred protection from cerebral malaria. Unlike vehicle treated animals, 2DG-treated animals did not develop cerebral malaria and survived until ultimately succumbing to fatal anemia. We did not find any differences in parasitemia or pathogen load in affected tissues. There were no differences in the kinetics of anemia. We also did not detect differences in immune infiltration in the brain or in blood-brain barrier permeability. Rather, on pathological analyses performed on the entire brain, we found that 2DG prevented the formation of thrombi and thrombotic complications. Using thromboelastography (TEG), we found that 2DG-treated animals formed clots that were significantly less strong and stable. Together, these data suggest that glucose metabolism is involved in inflammation-induced hemostasis and provide a potential therapeutic target in treatment of cerebral malaria. PMID- 30291190 TI - Verifying Larche-Cahn elasticity, a milestone of 20th-century thermodynamics. AB - Many materials phenomena are governed by the interaction between chemistry and mechanics. However, it was only in the second half of the 20th century that the theory of open system elasticity by Francis Larche and John W. Cahn concatenated the fields of solid mechanics and alloy chemistry. As the theory's central materials descriptors, the open system elastic parameters describe how solids deform under stress when solute can rearrange at equilibrium while the chemical potential is held constant. Here, we report experiments verifying the predictions for these parameters. We study the elasticity of nanoporous Pd-H and Pd-Au-H during load cycles imposed by a dynamic mechanical analyzer. Short diffusion paths afford fast equilibration of H in the local strain gradients that carry the macroscopic elastic deformation. The experiment is in excellent agreement with the theory, confirming a central prediction of one of the key contributions to 20th-century thermodynamics. PMID- 30291188 TI - Quantitative and functional posttranslational modification proteomics reveals that TREPH1 plays a role in plant touch-delayed bolting. AB - Environmental mechanical forces, such as wind and touch, trigger gene-expression regulation and developmental changes, called "thigmomorphogenesis," in plants, demonstrating the ability of plants to perceive such stimuli. In Arabidopsis, a major thigmomorphogenetic response is delayed bolting, i.e., emergence of the flowering stem. The signaling components responsible for mechanotransduction of the touch response are largely unknown. Here, we performed a high-throughput SILIA (stable isotope labeling in Arabidopsis)-based quantitative phosphoproteomics analysis to profile changes in protein phosphorylation resulting from 40 seconds of force stimulation in Arabidopsis thaliana Of the 24 touch-responsive phosphopeptides identified, many were derived from kinases, phosphatases, cytoskeleton proteins, membrane proteins, and ion transporters. In addition, the previously uncharacterized protein TOUCH-REGULATED PHOSPHOPROTEIN1 (TREPH1) became rapidly phosphorylated in touch-stimulated plants, as confirmed by immunoblots. TREPH1 fractionates as a soluble protein and is shown to be required for the touch-induced delay of bolting and gene-expression changes. Furthermore, a nonphosphorylatable site-specific isoform of TREPH1 (S625A) failed to restore touch-induced flowering delay of treph1-1, indicating the necessity of S625 for TREPH1 function and providing evidence consistent with the possible functional relevance of the touch-regulated TREPH1 phosphorylation. Taken together, these findings identify a phosphoprotein player in Arabidopsis thigmomorphogenesis regulation and provide evidence that TREPH1 and its touch induced phosphorylation may play a role in touch-induced bolting delay, a major component of thigmomorphogenesis. PMID- 30291191 TI - Reducing dynamin 2 (DNM2) rescues DNM2-related dominant centronuclear myopathy. AB - Centronuclear myopathies (CNM) are a group of severe muscle diseases for which no effective therapy is currently available. We have previously shown that reduction of the large GTPase DNM2 in a mouse model of the X-linked form, due to loss of myotubularin phosphatase MTM1, prevents the development of the skeletal muscle pathophysiology. As DNM2 is mutated in autosomal dominant forms, here we tested whether DNM2 reduction can rescue DNM2-related CNM in a knock-in mouse harboring the p.R465W mutation (Dnm2 RW/+) and displaying a mild CNM phenotype similar to patients with the same mutation. A single intramuscular injection of adeno associated virus-shRNA targeting Dnm2 resulted in reduction in protein levels 5 wk post injection, with a corresponding improvement in muscle mass and fiber size distribution, as well as an improvement in histopathological CNM features. To establish a systemic treatment, weekly i.p. injections of antisense oligonucleotides targeting Dnm2 were administered to Dnm2 RW/+mice for 5 wk. While muscle mass, histopathology, and muscle ultrastructure were perturbed in Dnm2 RW/+mice compared with wild-type mice, these features were indistinguishable from wild-type mice after reducing DNM2. Therefore, DNM2 knockdown via two different strategies can efficiently correct the myopathy due to DNM2 mutations, and it provides a common therapeutic strategy for several forms of centronuclear myopathy. Furthermore, we provide an example of treating a dominant disease by targeting both alleles, suggesting that this strategy may be applied to other dominant diseases.

AB - 177Lu-PSMA-617 enables targeted delivery of beta-particle radiation to prostate cancer. We determined its radiation dosimetry and relationships to pre therapeutic imaging and outcomes. METHODS: 30 patients with prostate cancer receiving 177Lu-PSMA-617 within a prospective clinical trial (ACTRN12615000912583) were studied. Screening 68Ga-PSMA-11 PET-CT demonstrated high PSMA-expression in all patients. Following therapy patients underwent quantitative SPECT-CT at 4, 24 and 96 hours. Pharmacokinetic uptake and clearance at a voxel level was calculated and translated into absorbed dose using voxel S values. Volumes-of-interest were drawn on normal tissues and tumor to assess radiation dose and a 'whole-body' tumor dose was also defined. Correlations between PSMA PET-CT parameters, dosimetry and biochemical and therapeutic response were analyzed to identify relationships between absorbed dose, tumor burden, and patient physiology. RESULTS: Mean absorbed dose to kidneys, submandibular and parotid glands, liver, spleen and bone marrow were 0.39, 0.44, 0.58, 0.1, 0.06 and 0.11 Gy/MBq, respectively. Median 'whole body' tumor absorbed dose was 11.55 Gy and correlated with PSA response at 12 weeks. A median dose of 14.1 Gy was observed in patients achieving PSA>=50% decline vs. 9.6 Gy for those achieving PSA<50% (p<0.01). Of 11 patients receiving a tumor dose less than 10 Gy only one achieved a PSA response >=50%. On screening PSMA PET, "whole body" tumor SUVmean correlated with mean absorbed dose (r=0.62) and SUVmax of the parotids also correlated with absorbed dose (r=0.67). There was an inverse correlation between tumor volume and mean dose to the parotids (r=-0.41) and kidneys (r= 0.43). Mean parotid dose was also reduced with increasing body mass (r=-0.41) and body surface area (r=-0.37). CONCLUSION: 177Lu-PSMA-617 delivers high-absorbed doses to tumor with significant correlation between "whole body" tutor dose and PSA response. Patients receiving less than 10 Gy were unlikely to achieve a fall in PSA>=50%. Significant correlations between aspects of screening 68Ga-PET-CT and tumor and normal tissue dose were observed providing a rationale for patient specific dosing. Reduced salivary and kidney doses was observed in patients with a higher tumor burden. Parotid dose also reduced with increasing body mass and body surface area. PMID- 30291193 TI - Evidence of local concentration of alpha-particles from 211At-labeled antibodies in liver metastasis tissue. AB - We investigated the local concentration of alpha-particles from 211At-labeled trastuzumab antibodies against HER2 (human epidermal growth factor receptor type2) antigens in liver metastasis tissue of mice. Mice carrying metastatic cancer in their liver were injected with 211At-agent. After 12 hours, the liver was removed and sliced, and two tissue samples of liver tissues without lesions and one containing metastatic lesions were mounted on the CR-39 plastic nuclear track detector. Microscope images of the tissues on CR-39 were acquired. After irradiation for 31 hours, the tissues were removed from CR-39. A microscope image of alpha-particle tracks on CR-39 was acquired after chemical etching. The positions of each tissue sample and the emitted alpha-particle tracks were adjusted to the same coordinates. The positional distribution of alpha-particle tracks emitted from 211At was consistent within the tissue. The alpha-particle tracks were mainly allocated in the tumor region of the tissue. The absorbed dose in individual cells segmented by 10 um intervals was obtained by the spectroscopic analysis of the LET (linear energy transfer) spectrum. The concentration efficiency, the track density ratio of alpha-particle tracks in the necrotized tissue, which was the tumor region, to the normal tissue, was found to be 6.0 +/- 0.2. In the tumor region, the high LET alpha-particles deposited a large enough dose to cause lethal damage to the cancer cells. The total absorbed dose ranged from 1 to 7 Gy with a peak at around 2 Gy, which would correspond to 2-3 times higher biologically equivalent dose because of the high RBE of the alpha-particles emitted from 211At.

AB - The use of Cerenkov radiation (CR) to activate nanoparticles in situ has recently been shown to control cancerous tumor growth. While the methodology has been demonstrated to work, to better understand the mechanistic steps, we develop a mathematical model that integrates Cerenkov physics, light interaction with matter, and photocatalytic reaction engineering. The model describes a detailed pathway for localized reactive oxygen species (ROS) generation from the Cerenkov assisted photocatalytic activity of TiO2 The model predictions are verified by comparing to the experimental reports in the literature. It is then used to investigate the effect of various parameters - size of TiO2 nanoparticles, concentration of TiO2 nanoparticles, and activity of the radionuclide [2-deoxy-2 18F-fluoro-D-glucose (18F-FDG)] on the number of photons and ROS generation. The importance of nanoparticle size on ROS generation for cancerous tumor growth control is elucidated, and an optimal size is proposed. The model presented here can be used for other radionuclides and nanoparticles and can provide guidance to the concentration and size of TiO2 nanoparticles and activity of radionuclide needed for efficient cancer therapy. PMID- 30291194 TI - Efficacy and Safety of High-Specific-Activity I-131 MIBG Therapy in Patients with Advanced Pheochromocytoma or Paraganglioma. AB - Patients with metastatic or unresectable (advanced) pheochromocytoma or paraganglioma (PPGL) have poor prognoses and few treatment options. This multicenter, phase 2 trial evaluated the efficacy and safety of high-specific activity I-131 meta-iodobenzylguanidine (HSA I-131 MIBG) in patients with advanced PPGL. Methods: In this open-label, single-arm study, 81 PPGL patients were screened for enrollment, and 74 received a treatment-planning dose of HSA I 131 MIBG. 68 patients with advanced PPGL received at least one therapeutic dose (~18.5 GBq) of HSA I-131 MIBG intravenously. The primary endpoint was the proportion of patients with at least a 50% reduction in baseline antihypertensive medication use lasting at least 6 months. Secondary endpoints included objective tumor response as assessed by Response Evaluation Criteria in Solid Tumors version 1.0; biochemical tumor marker response; overall survival (OS); and safety. Results: Of the 68 patients who received at least one therapeutic dose of HSA I-131 MIBG, 17 (25%; 95% CI, 16-37%) had a durable reduction in baseline antihypertensive medication use. Among 64 patients with evaluable disease, 59 (92%) had a partial response or stable disease as the best objective response within 12 months. Decreases in elevated (>=1.5 times the upper limit of normal (ULN) at baseline) serum CgA levels were observed with confirmed complete and partial responses 12 months after treatment in 19 of 28 patients (68%). The median OS duration was 36.7 months (95% CI, 29.9-49.1 months). The most common treatment-emergent adverse events were nausea, myelosuppression, and fatigue. No patients had drug-related acute hypertensive events during or after the administration of HSA I-131 MIBG. Conclusion: HSA I-131 MIBG offers multiple benefits, including sustained blood pressure control and tumor response in PPGL patients. PMID- 30291196 TI - An imager's guide to perineural tumor spread in head and neck cancers: radiological footprints on 18F-FDG PET with CT and MRI correlates. AB - Perineural spread refers to tumor growth along large nerves, a macroscopic analogue of microscopic perineural invasion. This phenomenon most commonly occurs in head and neck, but its incidence varies with histologic tumor subtype. Perineural spread results from a complex molecular interplay between tumor cells, nerves, and connective stroma. Perineural spread is clinically underdiagnosed despite its impact on patients' prognosis and management. The role of 18F fluorodeoxyglucose positron emission tomography (18F-FDG PET) in assessment of perineural spread in head and neck cancer remains to be explored, in contrast to magnetic resonance imaging (MRI) as the established gold standard. In patients with perineural spread, 18F-FDG PET shows both abnormality along the course of the involved nerve and muscular changes secondary to denervation. Assessment of perineural spread on 18F-FDG PET requires knowledge of relevant neural pathways, and it can be improved by correlation with anatomic imaging, additional image processing, and review of clinical context. PMID- 30291197 TI - Nuclear Neuroimaging in Social Anxiety Disorder: A Review. AB - In psychiatric research, nuclear imaging complements MRI. A recent neuroimaging review of social anxiety disorder focused predominantly on MRI, omitting the contribution of nuclear imaging methods. Nuclear imaging investigations of neural activity are sparse but have generally yielded results consistent with studies performed using MRI. Evidence for disturbances in neurotransmitter systems in social anxiety disorder is limited but suggestive of both serotonergic and dopaminergic dysfunction. Research focusing on additional molecular targets using existing and novel tracers, combined with recent technologic innovations and trends in collaborative methodology, may shape future nuclear imaging endeavors in this field.

PMID- 30291200 TI - Towards 'a balanced delegation' or enhancing global health governance? Analysis of parties' participation in the Conference of the Parties to WHO Framework Convention on Tobacco Control. AB - INTRODUCTION: The success of the WHO Framework Convention on Tobacco Control (FCTC) depends on parties' active participation in its governance and implementation, particularly via biennial Conference of the Parties (COP) meetings. The COP's efficacy is threatened by declining attendance and reductions in travel support for low-income and middle-income countries, and there are growing concerns about transparency and representation in country delegations amid industry efforts to shape their composition. METHODS: We examined parties' participation in the COP based on official meeting records, and the relationship between attendance and strength of tobacco control based on national global tobacco control reports. RESULTS: Attendance at the COP has decreased over time, and at several meetings would have fallen below 66% (the threshold for decision making) if it was not for high levels of participation among low-income and lower middle-income countries. Despite their higher attendance at COP meetings, these countries represent a smaller share of meeting attendees due to the smaller size of their delegations. Additionally, there has been a decline in the proportion of delegates from ministries of health and tobacco control focal points. Nationally, COP participation is correlated with stronger tobacco control policies; attendance by low-income countries has a strong correlation with implementation of advertising bans, while attendance among high-income and lower-middle-income countries shows a moderate correlation with implementation of tobacco taxes. CONCLUSIONS: Supporting states to actively engage in the COP is crucial for ongoing FCTC implementation, strengthening national capacity for tobacco control, and protecting the legitimacy and efficacy of global health governance. PMID- 30291201 TI - Heated tobacco product regulation under US law and the FCTC. AB - Tobacco companies are marketing new 'heated tobacco products' (HTPs) composed of battery-powered holders, chargers and tobacco plugs or sticks. The non-tobacco HTP components have escaped effective regulation under many countries' tobacco control laws because they are packaged and sold separately from the tobacco containing components. In the USA, HTPs cannot be marketed unless the Food and Drug Administration determines that allowing their sale would be 'appropriate for the protection of the public health'. Philip Morris International (PMI) is seeking permission to market its IQOS HTP in the USA with 'modified risk tobacco product' (MRTP) claims that it reduces exposure to harmful substances and is less harmful than other tobacco products. However, PMI has not submitted adequate scientific evidence required by US law to demonstrate that the product is significantly less harmful to users than other tobacco products, that its labelling would not mislead consumers, or that its marketing-with or without MRTP claims-would benefit the health of the population as a whole. Parties to the WHO Framework Convention on Tobacco Control (FCTC) must take measures to reduce tobacco use and nicotine addiction, and prevent false or misleading tobacco product labelling, advertising and promotions; the introduction of new HTPs must be assessed according to these goals. All components of HTPs should be regulated at least as stringently as existing tobacco products, including restrictions on labelling, advertising, promotion and sponsorship, sales to minors, price and taxation policies and smokefree measures. There is nothing in US law or the FCTC that prevents authorities from prohibiting HTPs. PMID- 30291202 TI - Tobacco taxation, illegal cigarette supply and geography. AB - BACKGROUND: In Uruguay, real tobacco taxes increased significantly during 2005 2010 and 2014-2017 and decreased during 2010-2014. The effects of these tax changes on illegal and legal cigarette usage differed significantly when we compared cities in the middle and south of the country with cities on the border. OBJECTIVE: This paper analyses whether supply side factors such as geographical location, distribution networks and the effectiveness of tobacco control play a significant role in sales and use of illegal cigarettes when tobacco taxes change, particularly given the price gap between legal and lower-priced illegal cigarettes. METHODS: Using the International Tobacco Control Evaluation Project Uruguay Survey data (2008, 2010, 2012 and 2014), choices among illegal, legal and roll-your-own cigarettes are estimated as a function of smokers' geographical location, an indicator of illegal cigarette supply, and controlling for socioeconomic and demographic variables. Smoking behaviours in Montevideo, Durazno and Maldonado were compared with those in two border cities, Salto and Rivera, where illegal cigarette prevalence may differ. FINDINGS: An increase in taxes on manufactured legal and roll-your-own cigarettes increased the odds that smokers in cities near the borders and women switched down to illegal cigarettes. City geographical location, controls effectiveness and distribution networks may play a significant role in accessibility of illegal cigarettes. To improve the effectiveness of increased taxes and prices in reducing smoking, policy-makers may consider specific policies intended to reduce access to illegal cigarettes, such as ratification and effective implementation of the Protocol to Eliminate Illicit Trade in Tobacco Products of WHO. PMID- 30291203 TI - In Vivo Expansion of Regulatory T Cells with IL-2/IL-2 Antibody Complex Protects against Transient Ischemic Stroke. AB - Regulatory T cells (Tregs) are known to protect against ischemic stroke. However, the low frequency of Tregs restricts their clinical utility. This study investigated whether expanding the number of Tregs in vivo with the IL-2/IL-2 antibody complex (IL-2/IL-2Ab) could improve stroke outcomes and further elaborated the mechanisms of protection in male mice. C57BL/6 mice received IL 2/IL-2Ab or isotype IgG (IsoAb) intraperitoneally for 3 d before (pretreatment) or starting 2 h after (posttreatment) 60 min middle cerebral artery occlusion (MCAO). IL-2/IL-2Ab selectively increased the number of Tregs in the blood, spleen, and lymph nodes. The IL-2/IL-2Ab treatment significantly reduced infarct volume, inhibited neuroinflammation, and improved sensorimotor functions, as manifested by rotarod test and foot fault test, compared with IsoAb-treated stroke mice. Treg depletion was then achieved by diphtheria toxin (DT) injection into transgenic mice expressing the DT receptor under the control of the Foxp3 promoter (DTR mice). The depletion of Tregs completely eliminated IL-2/IL-2Ab afforded neuroprotection. Interestingly, adoptive transfer of Tregs collected from IL-2/IL-2Ab-treated mice demonstrated more potent neuroprotection than an equal number of Tregs prepared from IsoAb-treated mice, suggesting that IL-2/IL 2Ab not only elevated Treg numbers, but also boosted their functions. Mechanistically, IL-2/IL-2Ab promoted the expression of CD39 and CD73 in expanded Tregs. CD73 deficiency diminished the protective effect of IL-2/IL-2Ab-stimulated Tregs in stroke mice. The results show that IL-2/IL-2Ab expands Tregs in vivo and boosts their immunomodulatory function. The activation of CD39/CD73 signaling in Tregs may participate as a potential mechanism underlying IL-2/IL-2Ab-afforded neuroprotection against ischemic brain injury.SIGNIFICANCE STATEMENT Regulatory T cells (Tregs) are known to protect against ischemic stroke. However, the low frequency of Tregs restricts their clinical utility. This study reported that systemic administration of the IL-2/IL-2 antibody complex (IL-2/IL-2Ab) robustly and selectively expanded the number of Tregs after stroke. IL-2/IL-2Ab pretreatment or posttreatment significantly improved stroke outcomes in a rodent model of ischemic stroke. We further discovered that IL-2/IL-2Ab not only elevated Treg numbers, but also boosted their functions and enhanced the expression of CD39 and CD73. Using CD73-deficient mice, we confirmed the importance of CD73 in the protective effect of IL-2/IL-2Ab-stimulated Tregs in stroke mice. These results shed light on IL-2/IL-2Ab as a clinically feasible immune therapy to boost endogenous Treg responses and ameliorate ischemic brain injury. PMID- 30291204 TI - Instantaneous Midbrain Control of Saccade Velocity. AB - The ability to interact with our environment requires the brain to transform spatially represented sensory signals into temporally encoded motor commands for appropriate control of the relevant effectors. For visually guided eye movements, or saccades, the superior colliculus (SC) is assumed to be the final stage of spatial representation, and instantaneous control of the movement is achieved through a rate code representation in the lower brain stem. We investigated whether SC activity in nonhuman primates (Macaca mulatta, 2 male and 1 female) also uses a dynamic rate code, in addition to the spatial representation. Noting that the kinematics of amplitude-matched movements exhibit trial-to-trial variability, we regressed instantaneous SC activity with instantaneous eye velocity and found a robust correlation throughout saccade duration. Peak correlation was tightly linked to time of peak velocity, the optimal efferent delay between SC activity and eye velocity was constant at ~12 ms both at onset and during the saccade, and SC neurons with higher firing rates exhibited stronger correlations. Moreover, the strong correlative relationship and constant efferent delay observation were preserved when eye movement profiles were substantially altered by a blink-induced perturbation. These results indicate that the rate code of individual SC neurons can control instantaneous eye velocity and argue against a serial process of spatial-to-temporal transformation. They also motivated us to consider a new framework of saccade control that does not incorporate traditionally accepted elements, such as the comparator and resettable integrator, whose neural correlates have remained elusive.SIGNIFICANCE STATEMENT All movements exhibit time-varying features that are under instantaneous control of the innervating neural command. At what stage in the brain is dynamical control present? It is well known that, in the skeletomotor system, neurons in the motor cortex use dynamical control. In the oculomotor system, in contrast, instantaneous velocity control of saccadic eye movements is not thought to be enforced until the lower brainstem. Using correlations between residual signals across trials, we show that instantaneous control of saccade velocity is present earlier in the visuo-oculomotor neuraxis, at the level of superior colliculus. The results require us to consider alternate frameworks of the neural control of saccades. PMID- 30291206 TI - Balloon remodeling-assisted Woven EndoBridge technique: description and feasibility for complex bifurcation aneurysms. AB - BACKGROUND: Woven EndoBridge (WEB) deployment remains challenging in aneurysms with a complex shape or orientation. OBJECTIVE: To show that embolization of wide neck bifurcation aneurysms using the WEB device balloon remodeling-assisted technique is a feasible and elegant endovascular solution compared with other techniques, such as balloon remodeling or stent-assisted coiling. MATERIALS AND METHODS: 10 cases (10 aneurysms in 9 patients) of balloon remodeling-assisted WEB treatment of unruptured complex bifurcation aneurysms were treated in our institution and retrospectively analyzed. Details of clinical presentations, technical details, perioperative and postoperative complications, and outcomes were collected. Immediate and long-term angiographic results were also evaluated. RESULTS: Aneurysms included six middle cerebral artery aneurysms, one anterior communicating artery aneurysm, one posterior communicating artery aneurysm, one basilar artery aneurysm, and one T-shaped carotid aneurysm. Mean dome width was 6.55 mm, mean neck size 4.5 mm, mean height 4.79 mm, and mean dome-to-neck ratio was 1:1.46. Treatment was performed exclusively with the balloon remodeling assisted WEB technique in all cases. The device was successfully deployed in every case. Periprocedural thromboembolic or hemorrhagic events did not occur. The modified Rankin Scale score at discharge was 0 for all patients. At mid-term or long-term angiographic follow-up, adequate occlusion was observed in 7 aneurysms from 8 controlled cases (87.5%), and one patient (2 aneurysms) did not have angiographic follow-up. CONCLUSION: The balloon remodeling-assisted WEB technique seems to be a safe and effective solution for endovascular treatment of unruptured wide-neck bifurcation aneurysms with specific complex anatomy. However, further studies are needed to evaluate the rate of complications and long-term efficacy. PMID- 30291205 TI - Temporal Contingencies Determine Whether Adaptation Strengthens or Weakens Normalization. AB - A fundamental and nearly ubiquitous feature of sensory encoding is that neuronal responses are strongly influenced by recent experience, or adaptation. Theoretical and computational studies have proposed that many adaptation effects may result in part from changes in the strength of normalization signals. Normalization is a "canonical" computation in which a neuron's response is modulated (normalized) by the pooled activity of other neurons. Here, we test whether adaptation can alter the strength of cross-orientation suppression, or masking, a paradigmatic form of normalization evident in primary visual cortex (V1). We made extracellular recordings of V1 neurons in anesthetized male macaques and measured responses to plaid stimuli composed of two overlapping, orthogonal gratings before and after prolonged exposure to two distinct adapters. The first adapter was a plaid consisting of orthogonal gratings and led to stronger masking. The second adapter presented the same orthogonal gratings in an interleaved manner and led to weaker masking. The strength of adaptation's effects on masking depended on the orientation of the test stimuli relative to the orientation of the adapters, but was independent of neuronal orientation preference. Changes in masking could not be explained by altered neuronal responsivity. Our results suggest that normalization signals can be strengthened or weakened by adaptation depending on the temporal contingencies of the adapting stimuli. Our findings reveal an interplay between two widespread computations in cortical circuits, adaptation and normalization, that enables flexible adjustments to the structure of the environment, including the temporal relationships among sensory stimuli.SIGNIFICANCE STATEMENT Two fundamental features of sensory responses are that they are influenced by adaptation and that they are modulated by the activity of other nearby neurons via normalization. Our findings reveal a strong interaction between these two aspects of cortical computation. Specifically, we show that cross-orientation masking, a form of normalization, can be strengthened or weakened by adaptation depending on the temporal contingencies between sensory inputs. Our findings support theoretical proposals that some adaptation effects may involve altered normalization and offer a network-based explanation for how cortex adjusts to current sensory demands. PMID- 30291207 TI - Predictors and impact of hemorrhagic transformations after endovascular thrombectomy in patients with acute large vessel occlusions. AB - BACKGROUND: Predictors and impact of hemorrhagic transformation (HT) after thrombectomy remain to be elucidated. OBJECTIVE: To investigate the independent predictors and impact of each hemorrhagic infarction (HI) and parenchymal hematoma (PH) after thrombectomy in patients with acute stroke due to intracranial large vessel occlusion (LVO). MATERIALS AND METHODS: We retrospectively reviewed data from 400 patients with acute LVO who underwent thrombectomy. Logistic regression analyses were performed to determine independent predictors of HI and PH on post-treatment CT scans. Associations between HT and poor outcome (modified Rankin Scalescore >=3) at 90 days were analyzed. RESULTS: HT was observed in 98 patients (62 HIs (15.5%) and 36 PHs (9%)). Independent predictors of HI were male sex, atrial fibrillation, and time from symptom onset to groin puncture. Hyperlipidemia (OR=0.221, 95% CI 0.064 to 0.767, P=0.017) and successful reperfusion (OR=0.246, 95% CI 0.093 to 0.651, P=0.005) were independently associated with a lower chance of PH, while hypertension (OR=2.260, 95% CI 1.014 to 5.035, P=0.046) and longer procedure duration (OR=1.046, 95% CI 1.016 to 1.077, P=0.003) were independently associated with a higher chance of PH. Only PH (OR=10.154, 95% CI 3.260 to 31.632, P<0.001) was an independent predictor of poor outcome. CONCLUSIONS: PH is independently associated with poor outcome, whereas HI does not predict outcome after thrombectomy in patients with acute LVO. Our findings suggest that rapid and successful reperfusion is essential to prevent PH in patients undergoing thrombectomy for acute LVO. In addition, our study suggests that hyperlipidemia is associated with a lower risk of PH in such patients. PMID- 30291208 TI - Selective compromise of hypoplastic posterior communicating artery variants with aneurysms treatable by coil embolization: clinical and radiologic outcomes. AB - BACKGROUND: Posterior communicating artery (PcoA) compromise may serve as adjunctive treatment in patients with hypoplastic variants of PcoA who undergo coil embolization of PcoA aneurysms. However, procedural safety and the propensity for later recanalization are still unclear. OBJECTIVE: To evaluate clinical and radiologic outcomes of coil embolization in this setting, focusing on compromise of PcoA. METHODS: As a retrospective review, we examined 250 patients harboring 291 aneurysms of hypoplastic PcoAs, all consecutively treated by coil embolization between January 2004 and June 2016. PcoA compromise was undertaken in conjunction with 81 of the treated aneurysms (27.8%; incomplete 53; complete 28). Medical records and radiologic data were assessed during extended monitoring. RESULTS: During the mean follow-up of 33.9+/-24.6 months (median 36 months), a total of 107 (36.8%) coiled aneurysms showed recanalization (minor 50; major 57). Recanalization rates were as follows: PcoA preservation 40.5% (85/210); incomplete PcoA occlusion 34.0% (18/53); complete PcoA occlusion 14.3% (4/28). Aneurysms >7 mm (HR 3.40; P<0.01), retreatment for recanalization (HR 3.23; P<0.01), and compromise of PcoA (P<0.01) emerged from multivariate analysis as significant risk factors for recanalization. Compared with PcoA preservation, complete PcoA compromise conferred more favorable outcomes (HR 0.160), whereas incomplete compromise of PcoA fell short of statistical significance. Thromboembolic infarction related to PcoA compromise did not occur in any patient. CONCLUSION: PcoA compromise in conjunction with coil embolization of PcoA aneurysms appears safe in hypoplastic variants of PcoA, helping to prevent recanalization if complete occlusion is achieved. PMID- 30291209 TI - Direct endovascular thrombectomy and bridging strategies for acute ischemic stroke: a network meta-analysis. AB - OBJECTIVES: The present Bayesian network meta-analysis aimed to compare the various strategies for acute ischemic stroke: direct endovascular thrombectomy within the thrombolysis window in patients with no contraindications to thrombolysis (DEVT); (2) direct endovascular thrombectomy secondary to contraindications to thrombolysis (DEVTc); (3) endovascular thrombectomy in addition to thrombolysis (IVEVT); and (4) thrombolysis without thrombectomy (IVT). METHODS: Six electronic databases were searched from their dates of inception to May 2017 to identify randomized controlled trials (RCTs) comparing IVT versus IVEVT, and prospective registry studies comparing IVEVT versus DEVT or IVEVT versus DEVTc. Network meta-analyses were performed using ORs and 95% CIs as the summary statistic. RESULTS: We identified 12 studies (5 RCTs, 7 prospective cohort) with a total of 3161 patients for analysis. There was no significant difference in good functional outcome at 90 days (modified Rankin Scale score <=2) between DEVT and IVEVT. There was no significant difference in mortality between all treatment groups. DEVT was associated with a 49% reduction in intracranial hemorrhage (ICH) compared with IVEVT (OR 0.51; 95% CI 0.33 to 0.79), due to reduction in rates of asymptomatic ICH (OR 0.47; 95% CI 0.29 to 0.76). Patients treated with DEVT had higher rates of reperfusion compared with IVEVT (OR 1.73; 95% CI 1.04 to 2.94). CONCLUSIONS: To our knowledge, this is the first network meta-analysis to be performed in the era of contemporary mechanical thrombectomy comparing DEVT and DEVTc. Our analysis suggests the addition of thrombolysis prior to thrombectomy for large vessel occlusions may not be associated with improved outcomes. PMID- 30291210 TI - Novel role for cardiac myocyte-derived beta-2 microglobulin in mediating cardiac fibrosis. AB - Hypertension is a significant risk factor for the development of cardiovascular ailments, including ischemic heart disease and diastolic dysfunction. In a recent issue of Clinical Science, Li et al. [Clin. Sci. (2018) 132, 1855-1874] report that beta-2 microglobulin (beta2M) is a novel secreted soluble factor released by cardiac myocytes during pressure overload that promotes profibrotic gene expression in cardiac fibroblasts both in vitro and in vivo Their study further identifies elevated beta2M levels as a possible biomarker for hypertensive patients with cardiac complications. The authors propose a mechanism that mechanically stretched cardiomyocytes release soluble beta2M which, through paracrine communication with cardiac fibroblasts, transactivates epidermal growth factor receptor (EGFR) to initiate acute signal transduction and up-regulate profibrotic genes, thereby promoting fibrosis. Here, we will discuss the background, significance of the study, alternative mechanisms, and future directions. PMID- 30291211 TI - Protective effects of Fragaria ananassa methanolic extract in a rat model of cadmium chloride-induced neurotoxicity. AB - Cadmium (Cd) is a common environmental toxicant that has harmful effects on plants, animals, and humans. The present study evaluated the protective effects of Fragaria ananassa methanolic extract (SME) on cadmium chloride (CdCl2)-induced neuronal toxicity in rats. Male albino rats were intraperitoneally (i.p) injected with CdCl2 (6.5 mg/kg) for 5 days with or without the SME (250 mg/kg). We measured the levels of Cd, lipid peroxidation (LPO), nitric oxide, glutathione (GSH), and oxidative enzymes such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase, and glutathione reductase (GR) in the whole brain homogenate. Compared with the control group, the Cd-intoxicated group showed a marked increase in the brain levels of Cd, LPO, and nitric oxide and a decrease in the levels of GSH and all tested antioxidant enzymes. Compared with Cd intoxicated rats, the rats pretreated with SME showed restoration of oxidative balance in the brain tissue. While the expression of brain SOD2, CAT, glutathione peroxidase 1, and GR was down-regulated in the Cd-treated group, the expression of these enzymes was up-regulated in rats pretreated with SME. In addition, administration of SME before CdCl2 increased the Bcl-2 expression, but significantly decreased the expression of Bax. Immunohistochemical analysis showed that compared with Cd-intoxicated rats, rats pretreated with SME showed a decrease in the protein expression of tumor necrosis factor alpha (TNF-alpha). Our findings indicate that SME protects the brain tissue from Cd-induced neuronal toxicity by improving the antioxidant system and increasing antiapoptotic and anti-inflammatory activities.

AB - MiR-140-5p is low expression and acts as a tumor suppressor in various types of human cancers. However, the potential role of miR-140-5p in retinoblastoma (RB) remains unknown. In the present study, we performed the miRNA microarray analysis to investigate whether miRNAs expression are associated with RB tumorigenesis in RB tissues. We found that a large set of miRNAs were ectopic expressions and miR 140-5p is most significantly down-regulated in human RB tissues compared with normal retinas. In addition, low miR-140-5p expression is associated with clinicopathological features (differentiation, invasion, T classification, N classification, cTNM stage, and largest tumor base) and poor survival in RB patients. Furthermore, our results showed that overexpression of miR-140-5p suppresses proliferation and induces apoptosis and cell cycle arrest in RB cell. Meanwhile, we confirmed that c-Met is the functional target of miR-140-5p in RB cell, and miR-140-5p expression is negatively correlated with c-Met in RB tissues. We also found that inhibition of c-Met also suppresses proliferation and induces apoptosis and cell cycle arrest in RB cell. Interestingly, c-Met can rescue the suppressive effects of miR-140-5p on RB cell growth and cell cycle arrest. More importantly, our findings indicated that miR-140-5p may inhibit cell growth via blocking c-Met/AKT/mTOR signaling pathway. Collectively, these results suggested that miR-140-5p might be a potential biomarker and target in the diagnosis and treatment of RB. PMID- 30291213 TI - The association of POLR2E rs3787016 polymorphism and cancer risk: a Chinese case control study and meta-analysis. AB - How single nucleotide polymorphisms in long non-coding RNAs are involved in cancer susceptibility remains poorly understood. We hypothesized that polymerase II polypeptide E (POLR2E) rs3787016 polymorphism, identified in a genome-wide association study of prostate cancer, might be a common genetic risk factor for cancer risk. To address this issue, we here conducted a case-control study to investigate the association of POLR2E rs3787016 polymorphism with risk of liver and lung cancer (including 800 normal controls, 480 liver cancer patients, and 550 lung cancer patients), followed by a meta-analysis. The genotyping was performed by polymerase chain reaction-restriction fragment length polymorphism and confirmed by sequencing. Although no significant association was found for rs3787016 with risk of liver or lung cancer, the further stratified analysis identified that rs3787016 contributed to liver cancer risk particularly for over than 60 years individuals who drink. Moreover, the meta-analysis demonstrated that rs3787016 was associated with overall cancer risk and prostate cancer risk. Collectively, the POLR2E rs3787016 polymorphism may be a valuable biomarker for cancer predisposition. PMID- 30291214 TI - Placenta-specific 9, a putative secretory protein, induces G2/M arrest and inhibits the proliferation of human embryonic hepatic cells. AB - Background: Placenta-specific 9 (Plac9) is a putative secreted protein that was first discovered in the context of embryogenesis. The expression pattern of Plac9 during embryogenesis, together with the results of recent reports, suggest that Plac9 may play a role in the liver development. The present study was conducted to investigate the secretory characteristics of Plac9 and its potential role in liver cell physiology. Methods: Immunofluorescence was employed to identify the subcellular distribution of Plac9 Cellular proliferative activity was analyzed by MTT assay and cell colony formation. The cell cycle distribution of Plac9 was analyzed by flow cytometry, and a functional analysis was performed using L02 cells following their stable infection with a lentivirus over-expressing Plac9 Results: Plac9 is a novel protein that is localized to the cytoplasm and may be secreted through the classic endoplasmic reticulum-Golgi route. The overexpression of Plac9 inhibits cell growth and induces G2/M phase arrest. Conclusion: Our findings reveal a novel role for Plac9 in regulating cell growth. PMID- 30291215 TI - The Chinese medicine Chai Hu Li Zhong Tang protects against non-alcoholic fatty liver disease by activating AMPKalpha. AB - An effective treatment for non-alcoholic fatty liver disease (NAFLD) is urgently needed. In the present study, we investigated whether the Chinese medicine Chai Hu Li Zhong Tang (CHLZT) could protect against the development of NAFLD. Rats in an animal model of NAFLD were treated with CHLZT, and their serum levels of cholesterol (TC), triglycerides (TG), high density lipoprotein-cholesterol (HDL C), low density lipoprotein-cholesterol (LDL-C), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were detected with an automatic biochemical analyzer. A cellular model of NAFLD was also established by culturing HepG2 cells in a medium that contained a long chain fat emulsion. Those cells were treated with CHLZT that contained serum from rats. After treatment, the levels of adenylate-activated protein kinase (AMPK) alpha (AMPKalpha), p AMPKalpha, acetyl coenzyme A carboxylase (ACC) alpha (ACCalpha), pACCalpha, PPARgamma, and SREBP-2 were detected. The AMPK agonist, acadesine (AICAR), was used as a positive control compound. Our results showed that CHLZT or AICAR significantly decreased the serum levels of TG, TC, LDL-C, AST, ALT, and insulin in NAFLD rats, and significantly increased their serum HDL-C levels. Treatments with CHLZT or AICAR significantly decreased the numbers of lipid droplets in NAFLD liver tissues and HepG2 cells. CHLZT and AICAR increased the levels of p AMPKalpha and PPARgamma in the NAFLD liver tissues and HepG2 cells, but decreased the levels of ACC-alpha, p-ACC-alpha, SREBP-2, and 3-hydroxyl-3-methylglutaryl coenzyme A reductase (HMGR). CHLZT protects against NAFLD by activating AMPKalpha, and also by inhibiting ACC activity, down-regulating SREBP2 and HMGR, and up-regulating PPAR-gamma. Our results suggest that CHLZT might be useful for treating NAFLD in the clinic. PMID- 30291216 TI - Inhibition of N-glycosylation by tunicamycin attenuates cell-cell adhesion via impaired desmosome formation in normal human epidermal keratinocytes. AB - N-Glycosylation affects protein functions such as location, stability, and susceptibility to proteases. Desmosomes in keratinocytes are essential to maintain epidermal tissue integrity to protect against environmental insults. However, it is not yet known whether N-glycosylation affects desmosomal functions in primary keratinocytes. Tunicamycin is an inhibitor of N-glycosylation that has been a useful tool in glycobiology. Therefore, we investigated the effect of inhibiting N-glycosylation by tunicamycin treatment on desmosomes in primary keratinocytes. In our experiments, cell-cell adhesive strength was reduced in tunicamycin-treated primary keratinocytes. TEM showed that desmosome formation was impaired by tunicamycin. Desmogleins (Dsgs) 1 and 3, which constitute the core structure of desmosomes, were well transported to the cell-cell borders, but the amount decreased and showed an aberrant distribution at the cell borders in tunicamycin-treated keratinocytes. The stability of both desmoglein proteins was also reduced, and they were degraded through both proteasomal and lysosomal pathways, although inhibiting degradation did not restore the cell-cell adhesion. Finally, tunicamycin induced desmosomal instability, enhancing their disassembly. In conclusion, these results indicate that N-glycosylation is critical to the desmosome complex to maintain cell-cell adhesive strength in primary keratinocytes. PMID- 30291217 TI - Biomarkers as predictive tools to test the in vivo anti-sarcoptic mange activity of propolis in naturally infested rabbits. AB - This study was designed to investigate the use of specific biomarkers, such as albumin, serum total protein, aspartate amino transferase (AST), globulin, alanine amino transferase (ALT), serum cortisol and alkaline phosphatase (ALP), as predictive tools for sarcoptic mange in rabbits. A total of 30 infested rabbits were equally divided into three treatment groups. Each group was administered either propolis, ivermectin, or propolis with ivermectin. Treated rabbit results were then compared to those of 10 infested untreated rabbits and 10 healthy rabbits. The impact of treatment was assessed via microscopic examination of skin scrapings, clinical signs, and blood measurements relating to the liver. This study demonstrated that topical application of 10 % propolis ointment resulted in complete recovery from clinical signs and complete absence of mites based on microscopic examination after 10-15 days of treatment. Moreover, AST, ALP, ALT, and cortisol were determined to be acceptable biomarkers to track the response of diseased rabbits to the therapeutic use of propolis. PMID- 30291218 TI - Acidic pH promotes nucleus pulposus cell senescence through activating the p38 MAPK pathway. AB - BACKGROUND: Nucleus pulposus (NP) cell senescence is an important cellular feature within the degenerative disc. It is known that a very acidic niche exists in the degenerative disc, which participates in regulating disc cell viability and matrix metabolism. OBJECTIVE: The present study was aimed to investigate the role and potential signaling transduction pathway of an acidic pH in regulating NP cell senescence. METHODS: Rat NP cells were cultured in an acidic pH of 7.2 close to that in a healthy disc (Control group) or in an acidic pH of 6.2 close to that in a severe degenerative disc (Experiment group) for 10 days. Additionally, the experimental NP cells were incubated along with the inhibitor SB203580 to analyze the role of p38 MAPK pathway in this process. RESULTS: Compared with the control NP cells, experimental NP cells showed a suppressed cell proliferation potency, an increased G0/G1 phase fraction whereas a decreased S-phase fraction and a declined telomerase activity, an up-regulated expression of senescence-related molecules (p16 and p53), and a down-regulated expression of matrix-related moleucles (aggrecan and collagen II). Further analysis showed that inhibition of the p38 MAPK pathway partly reversed effects of acidic pH of 6.2 on the experimental NP cells. CONCLUSION: The very acidic niche identified in a severe degenerative disc promotes NP cell senescence through regulating the p38 MAPK pathway. The present study provides a new mechanism that drives NP cell senescence during disc degeneration. PMID- 30291219 TI - Efficacy of novel immunotherapy regimens in patients with metastatic melanoma with germline CDKN2A mutations. AB - BACKGROUND: Inherited CDKN2A mutation is a strong risk factor for cutaneous melanoma. Moreover, carriers have been found to have poor melanoma-specific survival. In this study, responses to novel immunotherapy agents in CDKN2A mutation carriers with metastatic melanoma were evaluated. METHODS: CDKN2A mutation carriers that have developed metastatic melanoma and undergone immunotherapy treatments were identified among carriers enrolled in follow-up studies for familial melanoma. The carriers' responses were compared with responses reported in phase III clinical trials for CTLA-4 and PD-1 inhibitors. From publicly available data sets, melanomas with somatic CDKN2A mutation were analysed for association with tumour mutational load. RESULTS: Eleven of 19 carriers (58%) responded to the therapy, a significantly higher frequency than observed in clinical trials (p=0.03, binomial test against an expected rate of 37%). Further, 6 of the 19 carriers (32%) had complete response, a significantly higher frequency than observed in clinical trials (p=0.01, binomial test against an expected rate of 7%). In 118 melanomas with somatic CDKN2A mutations, significantly higher total numbers of mutations were observed compared with 761 melanomas without CDKN2A mutation (Wilcoxon test, p<0.001). CONCLUSION: Patients with CDKN2A mutated melanoma may have improved immunotherapy responses due to increased tumour mutational load, resulting in more neoantigens and stronger antitumorous immune responses. PMID- 30291220 TI - AXL Is a Putative Tumor Suppressor and Dormancy Regulator in Prostate Cancer. AB - Prostate cancer bone metastasis remains lethal and incurable, and often arises years after elimination of the primary tumor. It is unclear what underlies the decades-long clinical latency before recurrence, but evidence points to the existence of dormant residual tumor cells that disseminated before the primary tumor was eliminated. To design therapies to prevent progression of disseminated tumor cells (DTC) into lethal metastases, it is crucial to understand the mechanism(s) underlying this dormancy. The current study functionally validated our previous observation that implicated the GAS6/AXL axis in mediating DTC dormancy in the bone marrow. AXL-null and AXL-overexpressing prostate cancer cell lines were generated to determine if AXL was necessary and/or sufficient for dormancy. Characterization of these cells in vitro and using in vivo mouse models of DTC growth demonstrated that AXL was indeed sufficient to induce dormancy, but was unable to maintain it long-term and was not absolutely required for a dormancy period. Clinically, AXL expression correlated with longer survival in prostate cancer patients, and AXL was not expressed by cancer cells in primary or metastatic tissue. These data point to a tumor-suppressive role for AXL in prostate cancer, and future work is required to determine if AXL is expressed on human bone marrow DTCs.Implications: The ability of AXL to initiate but not maintain dormancy, coupled with its dispensability, suggests that targeting AXL alone will not prevent lethal metastatic outgrowth, and likely a cooperative network of factors exists to mediate long-term cellular dormancy.

AB - BACKGROUND The aim of this study was to explore the influence of ubiquitin associated protein 2-like (UBAP2L) on the growth and metastasis of hepatocellular carcinoma (HCC) and its potential underlying mechanism. MATERIAL AND METHODS UBAP2L gene was knocked down in SMMC-7721 by RNA interference and cell function experiments were performed. A subcutaneous xenograft tumor model was constructed to examine the effect of UBAP2L silence on HCC growth. Finally, the whole genomic microarrays were used to screen the potential mechanism of UBAP2L in regulating the biological function of HCC. RESULTS Compared with those in the control group, the cell proliferation and clone formation were significantly reduced, cell cycle was arrested in G2/M phase, the number of apoptotic cells was remarkably increased, and the abilities of vascular formation and cell migration and metastasis were dramatically weakened in the shUBAP2L group (All P<0.05). UBAP2L knockdown significantly suppressed the tumor growth of HCC in vivo. Moreover, a total of 320 genes changed significantly after UBAP2L knockdown, among which, 159 genes were upregulated and 161 genes were downregulated. Then, gene enrichment analysis revealed that PI3K/AKT and P53 signal pathway were the most significant in the top 10 enrichments. Finally, Western blot analysis verified that UBAP2L knockdown caused the increase of P21 and PTEN and decrease of CDK1, CCNB1, p PI3K, and p-AKT. CONCLUSIONS UBAP2L plays an oncogenic role in HCC, and knockdown of its expression significantly inhibits HCC growth and metastasis, which may be related to the regulation of PI3K/AKT and P53 signaling pathways by UBAP2L. PMID- 30291222 TI - A Case Report of Recurrent Metastatic Sebaceous Carcinoma Which Showed Favorable Response Tt Non-Fluorouracil Based Chemotherapy. AB - BACKGROUND Sebaceous carcinoma is a rare malignant tumor of the skin adnexa. While surgical resection is a treatment of choice in localized disease, frequent recurrence and distant metastasis make treatment difficult. Moreover, due to its rarity, optimal systemic treatment has not been determined. CASE REPORT A 59-year old female presented with disseminated subcutaneous nodules. Past history indicated she received repeated surgery, radiation therapy, and fluorouracil based systemic chemotherapy for recurrent sebaceous carcinoma. Following a subcutaneous nodule biopsy, histopathologic examination confirmed recurrent metastasis of sebaceous carcinoma. Because there was no established regimen as salvage chemotherapy, we decided to administer paclitaxel plus Adriamycin as a combination regimen after a thorough search of previous reports on PubMed. After the patient received 6 cycles of chemotherapy, all masses dramatically regressed. Unfortunately, several new lesions appeared 3 months after cessation of chemotherapy. Therefore, she was treated with anti-HGF antibody through a clinical trial. After that, she received nivolumab. But treatment with all the new agents did not show any response. Furthermore, her disease progressed rapidly. We re-challenged with the paclitaxel and Adriamycin regimen, 2 cycles of chemotherapy, and the follow-up positron emission tomography - computed tomography revealed marked decrement of multiple metastatic nodules. CONCLUSIONS Although several clinical reports have shown the effectiveness of fluorouracil, especially 5-fluorouracil-based chemotherapy, there has been a paucity of reports on other chemotherapeutic agents. We report a case of metastatic sebaceous carcinoma which showed favorable response to non-fluorouracil-based chemotherapy.

PMID- 30291224 TI - IL-17A-associated IKK-alpha signaling induced TSLP production in epithelial cells of COPD patients. AB - Thymic stromal lymphopoietin (TSLP) is a cytokine expressed in the epithelium, involved in the pathogenesis of chronic disease. IL-17A regulates airway inflammation, oxidative stress, and reduction of steroid sensitivity in chronic obstructive pulmonary disease (COPD). TSLP and IL-17A were measured in induced sputum supernatants (ISs) from healthy controls (HC), healthy smokers (HS), and COPD patients by enzyme-linked immunosorbent assay. Human bronchial epithelial cell line (16HBE) and normal bronchial epithelial cells were stimulated with rhIL 17A or ISs from COPD patients to evaluate TSLP protein and mRNA expression. The effects of the depletion of IL-17A in ISs, an anticholinergic drug, and the silencing of inhibitor kappa kinase alpha (IKKalpha) on TSLP production were evaluated in 16HBE cells. Coimmunoprecipitation of acetyl-histone H3(Lys14)/IKKalpha was evaluated in 16HBE cells treated with rhIL-17A and in the presence of the drug. TSLP and IL-17A levels were higher in ISs from COPD patients and HS compared with HC. TSLP protein and mRNA increased in 16HBE cells and in normal bronchial epithelial cells stimulated with ISs from COPD patients compared with ISs from HC and untreated cells. IKKalpha silencing reduced TSLP production in 16HBE cells stimulated with rhIL-17A and ISs from COPD patients. RhIL-17A increased the IKKalpha/acetyl-histone H3 immunoprecipitation in 16HBE cells. The anticholinergic drug affects TSLP protein and mRNA levels in bronchial epithelial cells treated with rhIL-17A or with ISs from COPD patients, and IKKalpha mediated acetyl-histone H3(Lys14). IL-17A/IKKalpha signaling induced the mechanism of chromatin remodeling associated with acetyl-histone H3(Lys14) and TSLP production in bronchial epithelial cells. Anticholinergic drugs might target TSLP derived from epithelial cells during the treatment of COPD. PMID- 30291226 TI - Response to Sachdeva et al: Brain Fogginess and SIBO Is Not a Mirage. PMID- 30291225 TI - A novel rat model of comorbid PTSD and addiction reveals intersections between stress susceptibility and enhanced cocaine seeking with a role for mGlu5 receptors. AB - PTSD is highly comorbid with cocaine use disorder (CUD), and cocaine users with PTSD + CUD are more resistant to treatment. Here we sought to develop a rat model of PTSD + CUD in order to identify the neurobiological changes underlying such comorbidity and screen potential medications for reducing cocaine seeking in the PTSD population. We utilized a predator scent stress model of PTSD, wherein rats received a single exposure to the fox pheromone 2,5-dihydro-2,4,5 trimethylthiazoline (TMT). One week after TMT exposure, stress-susceptible (susceptible), intermediate, and resilient phenotypes were detected and were consistent with behavioral, corticosterone, and gene expression profiles 3 weeks post TMT. We assessed phenotypic differences in cocaine self-administration, extinction, and cue-primed reinstatement. Susceptible rats exhibited deficits in extinction learning and increased cue-primed reinstatement that was not prevented by Ceftriaxone, an antibiotic that consistently attenuates the reinstatement of cocaine seeking. TMT-exposed resilient rats displayed increased mGlu5 gene expression in the amygdala and medial prefrontal cortex and did not display the enhanced cocaine seeking observed in susceptible rats. Combined treatment with the mGlu5 positive allosteric modulator 3-Cyano-N-(1,3-diphenyl-1 H-pyrazol-5 yl)benzamide (CDPPB), fear extinction, and ceftriaxone prevented the reinstatement of cocaine seeking in susceptible rats with fear extinction an important mediating condition. These results highlight the need for animal models of PTSD to consider stress-responsivity, as only a subset of trauma-exposed individuals develop PTSD and these individuals likely exhibit distinct neurobiological changes compared with trauma-exposed populations who are resilient to stress. This work further identifies glutamate homeostasis and mGlu5 as a target for treating relapse in comorbid PTSD-cocaine addiction. PMID- 30291227 TI - Evidence for magmatic carbon bias in 14C dating of the Taupo and other major eruptions. AB - Prehistoric timescales, volcanic hazard assessment, and understanding of volcanogenic climate events rely on accurate dating of prehistoric eruptions. Most late Quaternary eruptions are dated by 14C measurements on material from close to the volcano that may be contaminated by geologic-sourced infinite-age carbon. Here we show that 14C ages for the Taupo (New Zealand) First Millennium eruption are geographically arrayed, with oldest ages closer to the vent. The current eruption wiggle match date of 232 +/- 5 years CE is amongst the oldest. We present evidence that the older, vent-proximal 14C ages were biased by magmatic CO2 degassed from groundwater, and that the Taupo eruption occurred decades to two centuries after 232 CE. Our reinterpretation implies that ages for other proximally-dated, unobserved, eruptions may also be too old. Plateauing or declining tree ring cellulose delta13C and Delta14C values near a volcano indicate magmatic influence and may allow forecasting of super-eruptions. PMID- 30291228 TI - Powerful turbidity currents driven by dense basal layers. AB - Seafloor sediment flows (turbidity currents) are among the volumetrically most important yet least documented sediment transport processes on Earth. A scarcity of direct observations means that basic characteristics, such as whether flows are entirely dilute or driven by a dense basal layer, remain equivocal. Here we present the most detailed direct observations yet from oceanic turbidity currents. These powerful events in Monterey Canyon have frontal speeds of up to 7.2 m s-1, and carry heavy (800 kg) objects at speeds of >=4 m s-1. We infer they consist of fast and dense near-bed layers, caused by remobilization of the seafloor, overlain by dilute clouds that outrun the dense layer. Seabed remobilization probably results from disturbance and liquefaction of loose-packed canyon-floor sand. Surprisingly, not all flows correlate with major perturbations such as storms, floods or earthquakes. We therefore provide a new view of sediment transport through submarine canyons into the deep-sea. PMID- 30291229 TI - Myelo-lymphoid lineage restriction occurs in the human haematopoietic stem cell compartment before lymphoid-primed multipotent progenitors. AB - Capturing where and how multipotency is lost is crucial to understand how blood formation is controlled. Blood lineage specification is currently thought to occur downstream of multipotent haematopoietic stem cells (HSC). Here we show that, in human, the first lineage restriction events occur within the CD19 CD34+CD38-CD45RA-CD49f+CD90+ (49f+) HSC compartment to generate myelo-lymphoid committed cells with no erythroid differentiation capacity. At single-cell resolution, we observe a continuous but polarised organisation of the 49f+ compartment, where transcriptional programmes and lineage potential progressively change along a gradient of opposing cell surface expression of CLEC9A and CD34. CLEC9AhiCD34lo cells contain long-term repopulating multipotent HSCs with slow quiescence exit kinetics, whereas CLEC9AloCD34hi cells are restricted to myelo lymphoid differentiation and display infrequent but durable repopulation capacity. We thus propose that human HSCs gradually transition to a discrete lymphoid-primed state, distinct from lymphoid-primed multipotent progenitors, representing the earliest entry point into lymphoid commitment. PMID- 30291230 TI - Direct electrical quantification of glucose and asparagine from bodily fluids using nanopores. AB - Crucial steps in the miniaturisation of biosensors are the conversion of a biological signal into an electrical current as well as the direct sampling of bodily fluids. Here we show that protein sensors in combination with a nanopore, acting as an electrical transducer, can accurately quantify metabolites in real time directly from nanoliter amounts of blood and other bodily fluids. Incorporation of the nanopore into portable electronic devices will allow developing sensitive, continuous, and non-invasive sensors for metabolites for point-of-care and home diagnostics. PMID- 30291231 TI - Self-induced mechanical stress can trigger biofilm formation in uropathogenic Escherichia coli. AB - Bacterial biofilms represent an important medical problem; however, the mechanisms of the onset of biofilm formation are poorly understood. Here, using new controlled methods allowing high-throughput and reproducible biofilm growth, we show that biofilm formation is linked to self-imposed mechanical stress. In growing uropathogenic Escherichia coli colonies, we report that mechanical stress can initially emerge from the physical stress accompanying colony confinement within micro-cavities or hydrogel environments reminiscent of the cytosol of host cells. Biofilm formation can then be enhanced by a nutrient access-modulated feedback loop, in which biofilm matrix deposition can be particularly high in areas of increased mechanical and biological stress, with the deposited matrix further enhancing the stress levels. This feedback regulation can lead to adaptive and diverse biofilm formation guided by the environmental stresses. Our results suggest previously unappreciated mechanisms of the onset and progression of biofilm growth.

PMID- 30291234 TI - Genome mining of cyclodipeptide synthases unravels unusual tRNA-dependent diketopiperazine-terpene biosynthetic machinery. AB - Cyclodipeptide synthases (CDPSs) can catalyze the formation of two successive peptide bonds by hijacking aminoacyl-tRNAs from the ribosomal machinery resulting in diketopiperazines (DKPs). Here, three CDPS-containing loci (dmt1-3) are discovered by genome mining and comparative genome analysis of Streptomyces strains. Among them, CDPS DmtB1, encoded by the gene of dmt1 locus, can synthesize cyclo(L-Trp-L-Xaa) (with Xaa being Val, Pro, Leu, Ile, or Ala). Systematic mutagenesis experiments demonstrate the importance of the residues constituting substrate-binding pocket P1 for the incorporation of the second aa tRNA in DmtB1. Characterization of dmt1-3 unravels that CDPS-dependent machinery is involved in CDPS-synthesized DKP formation followed by tailoring steps of prenylation and cyclization to afford terpenylated DKP compounds drimentines. A phytoene-synthase-like family prenyltransferase (DmtC1) and a membrane terpene cyclase (DmtA1) are required for drimentines biosynthesis. These results set the foundation for further increasing the natural diversity of complex DKP derivatives. PMID- 30291233 TI - A rapid rate of sex-chromosome turnover and non-random transitions in true frogs. AB - The canonical model of sex-chromosome evolution predicts that, as recombination is suppressed along sex chromosomes, gametologs will progressively differentiate, eventually becoming heteromorphic. However, there are numerous examples of homomorphic sex chromosomes across the tree of life. This homomorphy has been suggested to result from frequent sex-chromosome turnovers, yet we know little about which forces drive them. Here, we describe an extremely fast rate of turnover among 28 species of Ranidae. Transitions are not random, but converge on several chromosomes, potentially due to genes they harbour. Transitions also preserve the ancestral pattern of male heterogamety, in line with the 'hot potato' model of sex-chromosome transitions, suggesting a key role for mutation load accumulation in non-recombining genomic regions. The importance of mutation load selection in frogs might result from the extreme heterochiasmy they exhibit, making frog sex chromosomes differentiate immediately from emergence and across their entire length. PMID- 30291235 TI - Latitude-dependent finescale turbulent shear generations in the Pacific tropical extratropical upper ocean. AB - Turbulent mixing, which is critically important for the equilibrium of ocean circulation, is controlled by finescale turbulent shear (S2) of oceanic flows through shear instability. Although the relationship between S2 and mixing is well understood, the latitude-dependent generation processes of S2 remain poorly known due to the lack of geographically extensive, long-term finescale velocity measurements. Here, using one-year ADCP data from 17 moorings along 143 degrees E, we first show that the upper-ocean S2 and its resultant mixing rate have a W shaped latitudinal distribution in the tropical-extratropical northwest Pacific with peaks at 0-2 degrees N, 12-14 degrees N, and 20-22 degrees N, respectively. Further analyses reveal that these S2 peaks are caused by vertically-sheared equatorial currents, parametric subharmonic instability of diurnal tide, and anticyclonic eddy's inertial chimney effect, respectively. As climate model simulations are sensitive to the mixing parameterizations, our findings highlight the need to incorporate the latitude-dependent generation mechanisms of S2 to improve climate models' prediction capabilities. PMID- 30291236 TI - Bone protection by inhibition of microRNA-182. AB - Targeting microRNAs recently shows significant therapeutic promise; however, such progress is underdeveloped in treatment of skeletal diseases with osteolysis, such as osteoporosis and rheumatoid arthritis (RA). Here, we identified miR-182 as a key osteoclastogenic regulator in bone homeostasis and diseases. Myeloid specific deletion of miR-182 protects mice against excessive osteoclastogenesis and bone resorption in disease models of ovariectomy-induced osteoporosis and inflammatory arthritis. Pharmacological treatment of these diseases with miR-182 inhibitors completely suppresses pathologic bone erosion. Mechanistically, we identify protein kinase double-stranded RNA-dependent (PKR) as a new and essential miR-182 target that is a novel inhibitor of osteoclastogenesis via regulation of the endogenous interferon (IFN)-beta-mediated autocrine feedback loop. The expression levels of miR-182, PKR, and IFN-beta are altered in RA and are significantly correlated with the osteoclastogenic capacity of RA monocytes. Our findings reveal a previously unrecognized regulatory network mediated by miR 182-PKR-IFN-beta axis in osteoclastogenesis, and highlight the therapeutic implications of miR-182 inhibition in osteoprotection. PMID- 30291237 TI - Targeting of NLRP3 inflammasome with gene editing for the amelioration of inflammatory diseases. AB - The NLRP3 inflammasome is a well-studied target for the treatment of multiple inflammatory diseases, but how to promote the current therapeutics remains a large challenge. CRISPR/Cas9, as a gene editing tool, allows for direct ablation of NLRP3 at the genomic level. In this study, we screen an optimized cationic lipid-assisted nanoparticle (CLAN) to deliver Cas9 mRNA (mCas9) and guide RNA (gRNA) into macrophages. By using CLAN encapsulating mCas9 and gRNA-targeting NLRP3 (gNLRP3) (CLANmCas9/gNLRP3), we disrupt NLRP3 of macrophages, inhibiting the activation of the NLRP3 inflammasome in response to diverse stimuli. After intravenous injection, CLANmCas9/gNLRP3 mitigates acute inflammation of LPS induced septic shock and monosodium urate crystal (MSU)-induced peritonitis. In addition, CLANmCas9/gNLRP3 treatment improves insulin sensitivity and reduces adipose inflammation of high-fat-diet (HFD)-induced type 2 diabetes (T2D). Thus, our study provides a promising strategy for treating NLRP3-dependent inflammatory diseases and provides a carrier for delivering CRISPR/Cas9 into macrophages. PMID- 30291238 TI - Structural properties of a haemophore facilitate targeted elimination of the pathogen Porphyromonas gingivalis. AB - Porphyromonas gingivalis is a keystone bacterial pathogen of chronic periodontitis. P. gingivalis is unable to synthesise the porphyrin macrocycle and relies on exogenous porphyrin, including haem or haem biosynthesis intermediates from host sources. We show that under the iron-limited conditions prevailing in tissue environments, P. gingivalis expresses a haemophore-like protein, HusA, to mediate the uptake of essential porphyrin and support pathogen survival within epithelial cells. The structure of HusA, together with titration studies, mutagenesis and in silico docking, show that haem binds in a hydrophobic groove on the alpha-helical structure without the typical iron coordination seen in other haemophores. This mode of interaction allows HusA to bind to a variety of abiotic and metal-free porphyrins with higher affinities than to haem. We exploit this unusual porphyrin-binding activity of HusA to target a prototypic deuteroporphyrin-metronidazole conjugate with restricted antimicrobial specificity in a Trojan horse strategy that effectively kills intracellular P. gingivalis. PMID- 30291239 TI - Nickel nanoparticles set a new record of strength. AB - Material objects with micrometer or nanometer dimensions can exhibit much higher strength than macroscopic objects, but this strength rarely approaches the maximum theoretical strength of the material. Here, we demonstrate that faceted single-crystalline nickel (Ni) nanoparticles exhibit an ultrahigh compressive strength (up to 34 GPa) unprecedented for metallic materials. This strength matches the available estimates of Ni theoretical strength. Three factors are responsible for this record-high strength: the large Ni shear modulus, the smooth edges and corners of the nanoparticles, and the thin oxide layer on the particle surface. This finding is supported by molecular dynamics simulations that closely mimic the experimental conditions, which show that the mechanical failure of the strongest particles is triggered by homogeneous nucleation of dislocation loops inside the particle. The nucleation of a stable loop is preceded by multiple nucleation attempts accompanied by unusually large local atomic displacements caused by thermal fluctuations.

Rodent studies suggest that memory consolidation depends on replay of stimulus-specific activity patterns during fast hippocampal "ripple" oscillations. Here, we measured replay in intracranial electroencephalography recordings in human epilepsy patients, and related replay to ripples. Stimulus-specific activity was identified using representational similarity analysis and then tracked during waking rest and sleep after encoding. Stimulus-specific gamma (30-90 Hz) activity during early (100-500 ms) and late (500-1200 ms) encoding is spontaneously reactivated during waking state and sleep, independent of later memory. Ripples during nREM sleep, but not during waking state, trigger replay of activity from the late time window specifically for remembered items. Ripple-triggered replay of activity from the early time window during nREM sleep is enhanced for forgotten items. These results provide the first electrophysiological evidence for replay related to memory consolidation in humans, and point to a prominent role of nREM ripple triggered replay in consolidation processes.

AB - Engineering heterogeneous micro-mechano-microenvironments of extracellular matrix is of great interest in tissue engineering, but spatial control over mechanical heterogeneity in three dimensions is still challenging given the fact that geometry and stiffness are inherently intertwined in fabrication. Here, we develop a layer-by-layer three-dimensional (3D) printing paradigm which achieves orthogonal control of stiffness and geometry by capitalizing on the conventionally adverse effect of oxygen inhibition on free-radical polymerization. Controlled oxygen permeation and inhibition result in photo-cured hydrogel layers with thicknesses only weakly dependent to the ultraviolet exposure dosage. The dosage is instead leveraged to program the crosslink density and stiffness of the cured structures. The programmable stiffness spans nearly an order of magnitude (E ~ 2-15 kPa) within the physiologically relevant range. We further demonstrate that extracellular matrices with programmed micro-mechano environments can dictate 3D cellular organization, enabling in vitro tissue reconstruction. PMID- 30291241 TI - Copy number load predicts outcome of metastatic colorectal cancer patients receiving bevacizumab combination therapy. AB - Increased copy number alterations (CNAs) indicative of chromosomal instability (CIN) have been associated with poor cancer outcome. Here, we study CNAs as potential biomarkers of bevacizumab (BVZ) response in metastatic colorectal cancer (mCRC). We cluster 409 mCRCs in three subclusters characterized by different degrees of CIN. Tumors belonging to intermediate-to-high instability clusters have improved outcome following chemotherapy plus BVZ versus chemotherapy alone. In contrast, low instability tumors, which amongst others consist of POLE-mutated and microsatellite-instable tumors, derive no further benefit from BVZ. This is confirmed in 81 mCRC tumors from the phase 2 MoMa study involving BVZ. CNA clusters overlap with CRC consensus molecular subtypes (CMS); CMS2/4 xenografts correspond to intermediate-to-high instability clusters and respond to FOLFOX chemotherapy plus mouse avastin (B20), while CMS1/3 xenografts match with low instability clusters and fail to respond. Overall, we identify copy number load as a novel potential predictive biomarker of BVZ combination therapy. PMID- 30291243 TI - High-performance nanomaterials formed by rigid yet extensible cyclic beta-peptide polymers. AB - Organisms have evolved biomaterials with an extraordinary convergence of high mechanical strength, toughness, and elasticity. In contrast, synthetic materials excel in stiffness or extensibility, and a combination of the two is necessary to exceed the performance of natural biomaterials. We bridge this materials property gap through the side-chain-to-side-chain polymerization of cyclic beta-peptide rings. Due to their strong dipole moments, the rings self-assemble into rigid nanorods, stabilized by hydrogen bonds. Displayed amines serve as functionalization sites, or, if protonated, force the polymer to adopt an unfolded conformation. This molecular design enhances the processability and extensibility of the biopolymer. Molecular dynamics simulations predict stick slip deformations dissipate energy at large strains, thereby, yielding toughness values greater than natural silks. Moreover, the synthesis route can be adapted to alter the dimensions and displayed chemistries of nanomaterials with mechanical properties that rival nature. PMID- 30291244 TI - Lateral inhibition by Martinotti interneurons is facilitated by cholinergic inputs in human and mouse neocortex. AB - A variety of inhibitory pathways encompassing different interneuron types shape activity of neocortical pyramidal neurons. While basket cells (BCs) mediate fast lateral inhibition between pyramidal neurons, Somatostatin-positive Martinotti cells (MCs) mediate a delayed form of lateral inhibition. Neocortical circuits are under control of acetylcholine, which is crucial for cortical function and cognition. Acetylcholine modulates MC firing, however, precisely how cholinergic inputs affect cortical lateral inhibition is not known. Here, we find that cholinergic inputs selectively augment and speed up lateral inhibition between pyramidal neurons mediated by MCs, but not by BCs. Optogenetically activated cholinergic inputs depolarize MCs through activation of beta2 subunit-containing nicotinic AChRs, not muscarinic AChRs, without affecting glutamatergic inputs to MCs. We find that these mechanisms are conserved in human neocortex. Cholinergic inputs thus enable cortical pyramidal neurons to recruit more MCs, and can thereby dynamically highlight specific circuit motifs, favoring MC-mediated pathways over BC-mediated pathways. PMID- 30291245 TI - Suppressor mutations in Rpf2-Rrs1 or Rpl5 bypass the Cgr1 function for pre ribosomal 5S RNP-rotation. AB - During eukaryotic 60S biogenesis, the 5S RNP requires a large rotational movement to achieve its mature position. Cryo-EM of the Rix1-Rea1 pre-60S particle has revealed the post-rotation stage, in which a gently undulating alpha-helix corresponding to Cgr1 becomes wedged between Rsa4 and the relocated 5S RNP, but the purpose of this insertion was unknown. Here, we show that cgr1 deletion in yeast causes a slow-growth phenotype and reversion of the pre-60S particle to the pre-rotation stage. However, spontaneous extragenic suppressors could be isolated, which restore growth and pre-60S biogenesis in the absence of Cgr1. Whole-genome sequencing reveals that the suppressor mutations map in the Rpf2 Rrs1 module and Rpl5, which together stabilize the unrotated stage of the 5S RNP. Thus, mutations in factors stabilizing the pre-rotation stage facilitate 5S RNP relocation upon deletion of Cgr1, but Cgr1 itself could stabilize the post rotation stage. PMID- 30291246 TI - Antigen-selective modulation of AAV immunogenicity with tolerogenic rapamycin nanoparticles enables successful vector re-administration. AB - Gene therapy mediated by recombinant adeno-associated virus (AAV) vectors is a promising treatment for systemic monogenic diseases. However, vector immunogenicity represents a major limitation to gene transfer with AAV vectors, particularly for vector re-administration. Here, we demonstrate that synthetic vaccine particles encapsulating rapamycin (SVP[Rapa]), co-administered with AAV vectors, prevents the induction of anti-capsid humoral and cell-mediated responses. This allows successful vector re-administration in mice and nonhuman primates. SVP[Rapa] dosed with AAV vectors reduces B and T cell activation in an antigen-selective manner, inhibits CD8+ T cell infiltration in the liver, and efficiently blocks memory T cell responses. SVP[Rapa] immunomodulatory effects can be transferred from treated to naive mice by adoptive transfer of splenocytes, and is inhibited by depletion of CD25+ T cells, suggesting a role for regulatory T cells. Co-administration of SVP[Rapa] with AAV vector represents a powerful strategy to modulate vector immunogenicity and enable effective vector re-administration. PMID- 30291247 TI - Graphene-enabled and directed nanomaterial placement from solution for large scale device integration. AB - Directed placement of solution-based nanomaterials at predefined locations with nanoscale precision limits bottom-up integration in semiconductor process technology. We report a method for electric-field-assisted placement of nanomaterials from solution by means of large-scale graphene layers featuring nanoscale deposition sites. The structured graphene layers are prepared via either transfer or synthesis on standard substrates, and then are removed once nanomaterial deposition is completed, yielding material assemblies with nanoscale resolution that cover surface areas >1 mm2. In order to demonstrate the broad applicability, we have assembled representative zero-dimensional, one dimensional, and two-dimensional semiconductors at predefined substrate locations and integrated them into nanoelectronic devices. Ultimately, this method opens a route to bottom-up integration of nanomaterials for industry-scale applications. PMID- 30291248 TI - Thermal and electrical signatures of a hydrodynamic electron fluid in tungsten diphosphide. AB - In stark contrast to ordinary metals, in materials in which electrons strongly interact with each other or with phonons, electron transport is thought to resemble the flow of viscous fluids. Despite their differences, it is predicted that transport in both conventional and correlated materials is fundamentally limited by the uncertainty principle applied to energy dissipation. Here we report the observation of experimental signatures of hydrodynamic electron flow in the Weyl semimetal tungsten diphosphide. Using thermal and magneto-electric transport experiments, we find indications of the transition from a conventional metallic state at higher temperatures to a hydrodynamic electron fluid below 20 K. The hydrodynamic regime is characterized by a viscosity-induced dependence of the electrical resistivity on the sample width and by a strong violation of the Wiedemann-Franz law. Following the uncertainty principle, both electrical and thermal transport are bound by the quantum indeterminacy, independent of the underlying transport regime. PMID- 30291249 TI - Bright room temperature single photon source at telecom range in cubic silicon carbide. AB - Single-photon emitters (SPEs) play an important role in a number of quantum information tasks such as quantum key distributions. In these protocols, telecom wavelength photons are desired due to their low transmission loss in optical fibers. In this paper, we present a study of bright single-photon emitters in cubic silicon carbide (3C-SiC) emitting in the telecom range. We find that these emitters are photostable and bright at room temperature with a count rate of ~ MHz. Altogether with the fact that SiC is a growth and fabrication-friendly material, our result may be relevant for future applications in quantum communication technology. PMID- 30291250 TI - Dynamic intercellular transport modulates the spatial patterning of differentiation during early neural commitment. AB - The initiation of heterogeneity within a population of phenotypically identical progenitors is a critical event for the onset of morphogenesis and differentiation patterning. Gap junction communication within multicellular systems produces complex networks of intercellular connectivity that result in heterogeneous distributions of intracellular signaling molecules. In this study, we investigate emergent systems-level behavior of the intercellular network within embryonic stem cell (ESC) populations and corresponding spatial organization during early neural differentiation. An agent-based model incorporates experimentally-determined parameters to yield complex transport networks for delivery of pro-differentiation cues between neighboring cells, reproducing the morphogenic trajectories during retinoic acid-accelerated mouse ESC differentiation. Furthermore, the model correctly predicts the delayed differentiation and preserved spatial features of the morphogenic trajectory that occurs in response to intercellular perturbation. These findings suggest an integral role of gap junction communication in the temporal coordination of emergent patterning during early differentiation and neural commitment of pluripotent stem cells. PMID- 30291251 TI - Testicular cancer. AB - Testicular cancer is the most common malignancy among men between 14 and 44 years of age, and its incidence has risen over the past two decades in Western countries. Both genetic and environmental factors contribute to the development of testicular cancer, for which cryptorchidism is the most common risk factor. Progress has been made in our understanding of the disease since the initial description of carcinoma in situ of the testis in 1972 (now referred to as germ cell neoplasia in situ), which has led to improved treatment options. The combination of surgery and cisplatin-based chemotherapy has resulted in a cure rate of >90% in patients with testicular cancer, although some patients become refractory to chemotherapy or have a late relapse; an improved understanding of the molecular determinants underlying tumour sensitivity and resistance may lead to the development of novel therapies for these patients. This Primer provides an overview of the biology, epidemiology, diagnosis and current treatment guidelines for testicular cancer, with a focus on germ cell tumours. We also outline areas for future research and what to expect in the next decade for testicular cancer. PMID- 30291254 TI - Testicular cancer. PMID- 30291252 TI - Aberrant expression of CITED2 promotes prostate cancer metastasis by activating the nucleolin-AKT pathway. AB - Despite many efforts to develop hormone therapy and chemotherapy, no effective strategy to suppress prostate cancer metastasis has been established because the metastasis is not well understood. We here investigate a role of CBP/p300 interacting transactivator with E/D-rich carboxy-terminal domain-2 (CITED2) in prostate cancer metastasis. CITED2 is highly expressed in metastatic prostate cancer, and its expression is correlated with poor survival. The CITED2 gene is highly activated by ETS-related gene that is overexpressed due to chromosomal translocation. CITED2 acts as a molecular chaperone to guide PRMT5 and p300 to nucleolin, thereby activating nucleolin. Informatics and experimental data suggest that the CITED2-nucleolin axis is involved in prostate cancer metastasis. This axis stimulates cell migration through the epithelial-mesenchymal transition and promotes cancer metastasis in a xenograft mouse model. Our results suggest that CITED2 plays a metastasis-promoting role in prostate cancer and thus could be a target for preventing prostate cancer metastasis. PMID- 30291253 TI - Intestinal microbiome adjusts the innate immune setpoint during colonization through negative regulation of MyD88. AB - Host pathways mediating changes in immune states elicited by intestinal microbial colonization are incompletely characterized. Here we describe alterations of the host immune state induced by colonization of germ-free zebrafish larvae with an intestinal microbial community or single bacterial species. We show that microbiota-induced changes in intestinal leukocyte subsets and whole-body host gene expression are dependent on the innate immune adaptor gene myd88. Similar patterns of gene expression are elicited by colonization with conventional microbiome, as well as mono-colonization with two different zebrafish commensal bacterial strains. By studying loss-of-function myd88 mutants, we find that colonization suppresses Myd88 at the mRNA level. Tlr2 is essential for microbiota induced effects on myd88 transcription and intestinal immune cell composition. PMID- 30291255 TI - The Quantum Mechanics of a Rolling Molecular "Nanocar". AB - We formulate a mathematical model of a rolling "molecular wheelbarrow"-a two wheeled nanoscale molecular machine-informed by experiments on molecular machines recently synthesized in labs. The model is a nonholonomic system (briefly, a system with non-integrable velocity constraints), for which no general quantization procedure exists. Nonetheless, we successfully embed the system in a Hamiltonian one and then quantize the result using geometric quantization and other tools; we extract from the result the quantum mechanics of the molecular wheelbarrow, and derive explicit formulae for the quantized energy spectrum. We also study a few variants of our model, some of which ignore the model's nonholonomic constraints. We show that these variants have different quantum energy spectra, indicating that in such systems one should not ignore the nonholonomic constraints, since they alter in a non-trivial way the energy spectrum of the molecule. PMID- 30291256 TI - A genomic Neolithic time transect of hunter-farmer admixture in central Poland. AB - Ancient DNA genome-wide analyses of Neolithic individuals from central and southern Europe indicate an overall population turnover pattern in which migrating farmers from Anatolia and the Near East largely replaced autochthonous Mesolithic hunter-gatherers. However, the genetic history of the Neolithic transition in areas lying north of the European Neolithic core region involved different levels of admixture with hunter-gatherers. Here we analyse genome-wide data of 17 individuals spanning from the Middle Neolithic to the Early Bronze Age (4300-1900 BCE) in order to assess the Neolithic transition in north-central Poland, and the local impacts of hunter-farmer contacts and Late Neolithic steppe migrations. We evaluate the influence of these on local populations and assess if and how they change through time, reporting evidence of recurrent hunter-farmer admixture over three millennia, and the co-existence of unadmixed hunter gatherers as late as 4300 BCE. During the Late Neolithic we report the appearance of steppe ancestry, but on a lesser scale than previously described for other central European regions, with evidence of stronger affinities to hunter gatherers than to steppe pastoralists. These results help understand the Neolithic palaeogenomics of another central European area, Kuyavia, and highlight the complexity of population interactions during those times. PMID- 30291257 TI - VOC breath profile in spontaneously breathing awake swine during Influenza A infection. AB - Influenza is one of the most common causes of virus diseases worldwide. Virus detection requires determination of Influenza RNA in the upper respiratory tract. Efficient screening is not possible in this way. Analysis of volatile organic compounds (VOCs) in breath holds promise for non-invasive and fast monitoring of disease progression. Breath VOC profiles of 14 (3 controls and 11 infected animals) swine were repeatedly analyzed during a complete infection cycle of Influenza A under high safety conditions. Breath VOCs were pre-concentrated by means of needle trap micro-extraction and analysed by gas chromatography mass spectrometry before infection, during virus presence in the nasal cavity, and after recovery. Six VOCs could be related to disease progression: acetaldehyde, propanal, n-propyl acetate, methyl methacrylate, styrene and 1,1 dipropoxypropane. As early as on day four after inoculation, when animals were tested positive for Influenza A, differentiation between control and infected animals was possible. VOC based information on virus infection could enable early detection of Influenza A. As VOC analysis is completely non-invasive it has potential for large scale screening purposes. In a perspective, breath analysis may offer a novel tool for Influenza monitoring in human medicine, animal health control or border protection. PMID- 30291258 TI - Oleoylethanolamide treatment affects gut microbiota composition and the expression of intestinal cytokines in Peyer's patches of mice. AB - The lipid sensor oleoylethanolamide (OEA), an endogenous high-affinity agonist of peroxisome proliferator-activated receptor-alpha (PPAR-alpha) secreted in the proximal intestine, is endowed with several distinctive homeostatic properties, such as control of appetite, anti-inflammatory activity, stimulation of lipolysis and fatty acid oxidation. When administered exogenously, OEA has beneficial effects in several cognitive paradigms; therefore, in all respects, OEA can be considered a hormone of the gut-brain axis. Here we report an unexplored modulatory effect of OEA on the intestinal microbiota and on immune response. Our study shows for the first time that sub-chronic OEA administration to mice fed a normal chow pellet diet, changes the faecal microbiota profile, shifting the Firmicutes:Bacteroidetes ratio in favour of Bacteroidetes (in particular Bacteroides genus) and decreasing Firmicutes (Lactobacillus), and reduces intestinal cytokines expression by immune cells isolated from Peyer's patches. Our results suggest that sub-chronic OEA treatment modulates gut microbiota composition towards a "lean-like phenotype", and polarises gut-specific immune responses mimicking the effect of a diet low in fat and high in polysaccharides content. PMID- 30291259 TI - Aromatic thermosetting copolyester bionanocomposites as reconfigurable bone substitute materials: Interfacial interactions between reinforcement particles and polymer network. AB - Development of porous materials consisting of polymer host matrix enriched with bioactive ceramic particles that can initiate the reproduction of cellular organisms while maintaining in vivo mechanical reliability is a long-standing challenge for synthetic bone substitutes. We present hydroxyapatite (HA) reinforced aromatic thermosetting copolyester (ATSP) matrix bionanocomposite as a potential reconfigurable bone replacement material. The nanocomposite is fabricated by solid-state mixing a matching set of precursor oligomers with biocompatible pristine HA particles. During endothermic condensation polymerization reaction, the constituent oligomers form a mechanochemically robust crosslinked aromatic backbone while incorporating the HAs into a self generated cellular structure. The morphological analysis demonstrates near homogenous distributions of the pristine HAs within the matrix. The HAs behave as a crack-arrester which promotes a more deformation-tolerant formation with relatively enhanced material toughness. Chain relaxation dynamics of the nanocomposite matrix during glass transition is modified via HA-induced segmental immobilization. Chemical characterization of the polymer backbone composition reveals the presence of a hydrogen-advanced covalent interfacial coupling mechanism between the HAs and ATSP matrix. This report lays the groundwork for further studies on aromatic thermosetting copolyester matrix bionanocomposites which may find applications in various artificial bone needs. PMID- 30291260 TI - Epidemiology, microbiology and therapeutic consequences of chronic osteomyelitis in northern China: A retrospective analysis of 255 Patients. AB - The study aimed to explore the epidemiology and clinical characteristics of chronic osteomyelitis observed in a northern China hospital. Clinical data of 255 patients with chronic osteomyelitis from January 2007 to January 2014 were collected and analyzed, including general information, disease data, treatment and follow-up data. Chronic osteomyelitis is more common in males and in the age group from 41-50 years of age. Common infection sites are the femur, tibiofibular, and hip joint. More g+ than g- bacterial infections were observed, with S. aureus the most commonly observed pathogenic organism. The positive detection rate from debridement bacterial culture is 75.6%. The detection rate when five samples are sent for bacterial culture is 90.6%, with pathogenic bacteria identified in 82.8% of cases. The two-stage debridement method (87.0%) has higher first curative rate than the one-stage debridement method (71.2%). To improve detection rate using bacterial culture, at least five samples are recommended. Treatment of chronic osteomyelitis with two-stage debridement, plus antibiotic-loaded polymethylmethacrylate (PMMA) beads provided good clinical results in this study and is therefore recommended. PMID- 30291261 TI - High Speed, High Density Intraoperative 3D Optical Topographical Imaging with Efficient Registration to MRI and CT for Craniospinal Surgical Navigation. AB - Intraoperative image-guided surgical navigation for craniospinal procedures has significantly improved accuracy by providing an avenue for the surgeon to visualize underlying internal structures corresponding to the exposed surface anatomy. Despite the obvious benefits of surgical navigation, surgeon adoption remains relatively low due to long setup and registration times, steep learning curves, and workflow disruptions. We introduce an experimental navigation system utilizing optical topographical imaging (OTI) to acquire the 3D surface anatomy of the surgical cavity, enabling visualization of internal structures relative to exposed surface anatomy from registered preoperative images. Our OTI approach includes near instantaneous and accurate optical measurement of >250,000 surface points, computed at >52,000 points-per-second for considerably faster patient registration than commercially available benchmark systems without compromising spatial accuracy. Our experience of 171 human craniospinal surgical procedures, demonstrated significant workflow improvement (41 s vs. 258 s and 794 s, p < 0.05) relative to benchmark navigation systems without compromising surgical accuracy. Our advancements provide the cornerstone for widespread adoption of image guidance technologies for faster and safer surgeries without intraoperative CT or MRI scans. This work represents a major workflow improvement for navigated craniospinal procedures with possible extension to other image-guided applications. PMID- 30291262 TI - Pathological macromolecular crystallographic data affected by twinning, partial disorder and exhibiting multiple lattices for testing of data processing and refinement tools. AB - Twinning is a crystal growth anomaly, which has posed a challenge in macromolecular crystallography (MX) since the earliest days. Many approaches have been used to treat twinned data in order to extract structural information. However, in most cases it is usually simpler to rescreen for new crystallization conditions that yield an untwinned crystal form or, if possible, collect data from non-twinned parts of the crystal. Here, we report 11 structures of engineered variants of the E. coli enzyme N-acetyl-neuraminic lyase which, despite twinning and incommensurate modulation, have been successfully indexed, solved and deposited. These structures span a resolution range of 1.45-2.30 A, which is unusually high for datasets presenting such lattice disorders in MX and therefore these data provide an excellent test set for improving and challenging MX data processing programs. PMID- 30291263 TI - Machine-learning based lipid mediator serum concentration patterns allow identification of multiple sclerosis patients with high accuracy. AB - Based on increasing evidence suggesting that MS pathology involves alterations in bioactive lipid metabolism, the present analysis was aimed at generating a complex serum lipid-biomarker. Using unsupervised machine-learning, implemented as emergent self-organizing maps of neuronal networks, swarm intelligence and Minimum Curvilinear Embedding, a cluster structure was found in the input data space comprising serum concentrations of d = 43 different lipid-markers of various classes. The structure coincided largely with the clinical diagnosis, indicating that the data provide a basis for the creation of a biomarker (classifier). This was subsequently assessed using supervised machine-learning, implemented as random forests and computed ABC analysis-based feature selection. Bayesian statistics-based biomarker creation was used to map the diagnostic classes of either MS patients (n = 102) or healthy subjects (n = 301). Eight lipid-markers passed the feature selection and comprised GluCerC16, LPA20:4, HETE15S, LacCerC24:1, C16Sphinganine, biopterin and the endocannabinoids PEA and OEA. A complex classifier or biomarker was developed that predicted MS at a sensitivity, specificity and accuracy of approximately 95% in training and test data sets, respectively. The present successful application of serum lipid marker concentrations to MS data is encouraging for further efforts to establish an MS biomarker based on serum lipidomics. PMID- 30291264 TI - Unusual bidirectional frequency dependence of dynamical susceptibility in hexagonal intermetallic Pr2Ni0.95Si2.95. AB - In this study, the synthesis of a novel ternary intermetallic compound Pr2Ni0.95Si2.95 forming in single phase only by deliberately introducing vacancies in Ni/Si site is reported. The detailed studies on dc magnetization, heat capacity, ac magnetization & associated dynamical scaling, different types of non-equilibrium dynamical behaviour, viz., magnetic relaxation behaviour as a function of wait time and temperature, aging phenomena, and magnetic memory effect firmly establish that the compound exhibits spin freezing behaviour below 3.3 K (Tf). However, below Tf, temperature dependence of ac susceptibility data exhibit an additional peak that shows reverse frequency dependence to that generally observed in a glassy system. The unusual bidirectional frequency dependence in a single magnetic system is of significant interest and rarely reported in literature. Competing exchange interaction arising from c/a ~ 1 and crystallographic randomness driven magnetic phase separation has been argued to be responsible for such observation. The reverse frequency shift of the low temperature peak has been described on the basis of a simple phenomenological model proposed in this work. PMID- 30291265 TI - Site-Specific Labelling of Multidomain Proteins by Amber Codon Suppression. AB - The access to information on the dynamic behaviour of large proteins is usually hindered as spectroscopic methods require the site-specific attachment of biophysical probes. A powerful emerging tool to tackle this issue is amber codon suppression. Till date, its application on large and complex multidomain proteins of MDa size has not been reported. Herein, we systematically investigate the feasibility to introduce different non-canonical amino acids into a 540 kDa homodimeric fatty acid synthase type I by genetic code expansion with subsequent fluorescent labelling. Our approach relies on a microplate-based reporter assay of low complexity using a GFP fusion protein to quickly screen for sufficient suppression conditions. Once identified, these findings were successfully utilized to upscale both the expression scale and the protein size to full-length constructs. These fluorescently labelled samples of fatty acid synthase were subjected to initial biophysical experiments, including HPLC analysis, activity assays and fluorescence spectroscopy. Successful introduction of such probes into a molecular machine such as fatty acid synthases may pave the way to understand the conformational variability, which is a primary intrinsic property required for efficient interplay of all catalytic functionalities, and to engineer them. PMID- 30291266 TI - Cytometry meets next-generation sequencing - RNA-Seq of sorted subpopulations reveals regional replication and iron-triggered prophage induction in Corynebacterium glutamicum. AB - Phenotypic diversification is key to microbial adaptation. Currently, advanced technological approaches offer insights into cell-to-cell variation of bacterial populations at a spatiotemporal resolution. However, the underlying molecular causes or consequences often remain obscure. In this study, we developed a workflow combining fluorescence-activated cell sorting and RNA-sequencing, thereby allowing transcriptomic analysis of 106 bacterial cells. As a proof of concept, the workflow was applied to study prophage induction in a subpopulation of Corynebacterium glutamicum. Remarkably, both the phage genes and flanking genomic regions of the CGP3 prophage revealed significantly increased coverage upon prophage induction - a phenomenon that to date has been obscured by bulk approaches. Genome sequencing of prophage-induced populations suggested regional replication at the CGP3 locus in C. glutamicum. Finally, the workflow was applied to unravel iron-triggered prophage induction in early exponential cultures. Here, an up-shift in iron levels resulted in a heterogeneous response of an SOS (PdivS) reporter. RNA-sequencing of the induced subpopulation confirmed induction of the SOS response triggering also activation of the CGP3 prophage. The fraction of CGP3-induced cells was enhanced in a mutant lacking the iron regulator DtxR suffering from enhanced iron uptake. Altogether, these findings demonstrate the potential of the established workflow to gain insights into the phenotypic dynamics of bacterial populations. PMID- 30291267 TI - Realizing multi-functional all-optical data processing on nanoscale SiC waveguides. AB - All-optical logics are realized on nanoscale SiC waveguides with add-drop micro ring functionality, including the TE/TM polarized data decoding, the dual-port Kerr switching and gating beyond 12 Gbit/s. With employing the C-C bond enriched SiC thin film upon thermal oxide, the nonlinear refractive index of up to 2.44 * 10-12 cm2/W enables the asymmetric waveguide with polarization distinguishable transmission, which provides a polarization-selectivity to discreminate the TE/TM polarized data decoding with an nearly 9-dB extinction ratio. The TE/TM polarized decoding performance is comparable with a state-of-the-art fiberized in-line polarizer. The complementary transmission in the bus waveguide port facilitates the dual-port Kerr switching for data format conversion/inversion in both add/drop channels. Owing to the TE/TM polarization discriminated throughput, the asymmetric add-drop waveguide micro-ring also permits all-optical AND logic gating functions, where the ON-state outputs only if the pump bit is set at ON state and the probe bit with matched polarization. These results reveal the multi functionality of the nanoscale SiC add-drop micro-ring waveguide for future photonic logics on chip. PMID- 30291268 TI - Technology Transfer of the Microphysiological Systems: A Case Study of the Human Proximal Tubule Tissue Chip. AB - The adoption of a new technology into basic research, and industrial and clinical settings requires rigorous testing to build confidence in the reproducibility, reliability, robustness, and relevance of these models. Tissue chips are promising new technology, they have the potential to serve as a valuable tool in biomedical research, as well as pharmaceutical development with regards to testing for efficacy and safety. The principal goals of this study were to validate a previously established proximal tubule tissue chip model in an independent laboratory and to extend its utility to testing of nephrotoxic compounds. Here, we evaluated critical endpoints from the tissue chip developer laboratory, focusing on biological relevance (long-term viability, baseline protein and gene expression, ammoniagenesis, and vitamin D metabolism), and toxicity biomarkers. Tissue chip experiments were conducted in parallel with traditional 2D culture conditions using two different renal proximal tubule epithelial cell sources. The results of these studies were then compared to the findings reported by the tissue chip developers. While the overall transferability of this advanced tissue chip platform was a success, the reproducibility with the original report was greatly dependent on the cell source. This study demonstrates critical importance of developing microphysiological platforms using renewable cell sources. PMID- 30291269 TI - Real-time Brain Tumor imaging with endogenous fluorophores: a diagnosis proof-of concept study on fresh human samples. AB - The primary line of therapy for high-grade brain tumor is surgical resection, however, identifying tumor margins in vivo remains a major challenge. Despite the progress in computer-assisted imaging techniques, biopsy analysis remains the standard diagnostic tool when it comes to delineating tumor margins. Our group aims to answer this challenge by exploiting optical imaging of endogenous fluorescence in order to provide a reliable and reproducible diagnosis close to neuropathology. In this study, we first establish the ability of two-photon microscopy (TPM) to discriminate normal brain tissue from glioblastomas and brain metastasis using the endogenous fluorescence response of fresh human brain sample. Two-photon fluorescence images were compared to gold standard neuropathology. "Blind" diagnosis realized by a neuropathologist on a group of TPM images show a good sensitivity, 100%, and specificity, 50% to discriminate non tumoral brain tissue versus glioblastoma or brain metastasis. Quantitative analysis on spectral and fluorescence lifetime measurements resulted in building a scoring system to discriminate brain tissue samples. PMID- 30291270 TI - Chemical transfer of dissolved organic matter from surface seawater to sea spray water-soluble organic aerosol in the marine atmosphere. AB - It is critical to understand how variations in chemical composition in surface seawater (SSW) affect the chemistry of marine atmospheric aerosols. We investigated the sea-to-air transfer of dissolved organic carbon (DOC) via cruise measurements of both ambient aerosols and SSW in the Oyashio and its coastal regions, the western subarctic Pacific during early spring. Sea spray aerosols (SSAs) were selected based on the stable carbon isotope ratio of water-soluble organic carbon (WSOC) (delta13CWSOC) and concentrations of glucose as a molecular tracer in marine aerosols together with local surface wind speed data. For both SSA and SSW samples, excitation-emission matrices were obtained to examine the transfer of fluorescent organic material. We found that the ratios of fluorescence intensity of humic-like and protein-like substances in the submicrometer SSAs were significantly larger than those in the bulk SSW (~63%). This ratio was also larger for the supermicrometer SSAs than for the SSW. The results suggest significant decomposition of protein-like DOC on a timescale of <12-24 h and/or preferential production of humic-like substances in the atmospheric aerosols regardless of the particle size. This study provides unique insights into the complex transfer of DOC from the ocean surface to the atmosphere. PMID- 30291271 TI - Dual Porosity Protein-based Scaffolds with Enhanced Cell Infiltration and Proliferation. AB - 3D dual porosity protein-based scaffolds have been developed using the combination of foaming and freeze-drying. The suggested approach leads to the production of large, highly porous scaffolds with negligible shrinkage and deformation compared to the conventional freeze-drying method. Scanning electron microscopy, standard histological processing and mercury intrusion porosimetry confirmed the formation of a dual network in the form of big primary pores (243 +/- 14 um) embracing smaller secondary pores (42 +/- 3 um) opened onto their surface, resembling a vascular network. High interconnectivity of the pores, confirmed by micro-CT, is shown to improve diffusion kinetics and support a relatively uniform distribution of isolated human dental pulp stem cells within the scaffold compared to conventional scaffolds. Dual network scaffolds indicate more than three times as high cell proliferation capability as conventional scaffolds in 14 days. PMID- 30291272 TI - Structural insights into pro-aggregation effects of C. elegans CRAM-1 and its human ortholog SERF2. AB - Toxic protein aggregates are key features of progressive neurodegenerative diseases. In addition to "seed" proteins diagnostic for each neuropathy (e.g., Abeta1-42 and tau in Alzheimer's disease), aggregates contain numerous other proteins, many of which are common to aggregates from diverse diseases. We reported that CRAM-1, discovered in insoluble aggregates of C. elegans expressing Q40::YFP, blocks proteasomal degradation of ubiquitinated proteins and thus promotes aggregation. We now show that CRAM-1 contains three alpha-helical segments forming a UBA-like domain, structurally similar to those of mammalian adaptor proteins (e.g. RAD23, SQSTM1/p62) that shuttle ubiquitinated cargos to proteasomes or autophagosomes for degradation. Molecular modeling indicates that CRAM-1, through this UBA-like domain, can form tight complexes with mono- and di ubiquitin and may thus prevent tagged proteins from interacting with adaptor/shuttle proteins required for degradation. A human ortholog of CRAM-1, SERF2 (also largely disordered), promotes aggregation in SH-SY5Y-APPSw human neuroblastoma cells, since SERF2 knockdown protects these cells from amyloid formation. Atomistic molecular-dynamic simulations predict spontaneous unfolding of SERF2, and computational large-scale protein-protein interactions predict its stable binding to ubiquitins. SERF2 is also predicted to bind to most proteins screened at random, although with lower average stability than to ubiquitins, suggesting roles in aggregation initiation and/or progression. PMID- 30291273 TI - Novel multiplex PCR-SSP method for centromeric KIR allele discrimination. AB - Allelic diversity of the KIR2DL receptors drive differential expression and ligand-binding affinities that impact natural killer cell function and patient outcomes for diverse cancers. We have developed a global intermediate resolution amplification-refractory mutation system (ARMS) PCR-SSP method for distinguishing functionally relevant subgroups of the KIR2DL receptors, as defined by phylogenetic study of the protein sequences. Use of the ARMS design makes the method reliable and usable as a kit, with all reactions utilizing the same conditions. Six reactions define six subgroups of KIR2DL1; four reactions define three subgroups of KIR2DL2; and five reactions define four subgroups of KIR2DL3. Using KIR allele data from a cohort of 426 European-Americans, we identified the most common KIR2DL subtypes and developed the high-throughput PCR-based methodology, which was validated on a separate cohort of 260 healthy donors. Linkage disequilibrium analysis between the different KIR2DL alleles revealed that seven allelic combinations represent more than 95% of the observed population genotypes for KIR2DL1/L2/L3. In summary, our findings enable rapid typing of the most common KIR2DL receptor subtypes, allowing more accurate prediction of co-inheritance and providing a useful tool for the discrimination of observed differences in surface expression and effector function among NK cells exhibiting disparate KIR2DL allotypes. PMID- 30291274 TI - The quantum Zeno and anti-Zeno effects with non-selective projective measurements. AB - In studies of the quantum Zeno and anti-Zeno effects, it is usual to consider rapid projective measurements with equal time intervals being performed on the system to check whether or not the system is in the initial state. These projective measurements are selective measurements in the sense that the measurement results are read out and only the case where all the measurement results correspond to the initial state is considered in the analysis of the effect of the measurements. In this paper, we extend such a treatment to consider the effect of repeated non-selective projective measurements - only the final measurement is required to correspond to the initial state, while we do not know the results of the intermediate measurements. We present a general formalism to derive the effective decay rate of the initial quantum state with such nonselective measurements. Importantly, we show that there is a difference between using non-selective projective measurements and the usual approach of considering only selective measurements only if we go beyond the weak system environment coupling regime in models other than the usual population decay models. As such, we then apply our formalism to investigate the quantum Zeno and anti-Zeno effects for three exactly solvable system-environment models: a single two-level system undergoing dephasing, a single two-level system interacting with an environment of two-level systems and a large spin undergoing dephasing. Our results show that the quantum Zeno and anti-Zeno effects in the presence of non selective projective measurements can differ very significantly as compared to the repeated selective measurement scenario. PMID- 30291275 TI - Fiber-bundle illumination: realizing high-degree time-multiplexed multifocal multiphoton microscopy with simplicity. AB - High-degree time-multiplexed multifocal multiphoton microscopy was expected to provide a facile path to scanningless optical-sectioning and the fast imaging of dynamic three-dimensional biological systems. However, physical constraints on typical time multiplexing devices, arising from diffraction in the free-space propagation of light waves, lead to significant manufacturing difficulties and have prevented the experimental realization of high-degree time multiplexing. To resolve this issue, we have developed a novel method using optical fiber bundles of various lengths to confine the diffraction of propagating light waves and to create a time multiplexing effect. Through this method, we experimentally demonstrate the highest degree of time multiplexing ever achieved in multifocal multiphoton microscopy (~50 times larger than conventional approaches), and hence the potential of using simply-manufactured devices for scanningless optical sectioning of biological systems. PMID- 30291276 TI - Developmental asynchrony and antagonism of sex determination pathways in a lizard with temperature-induced sex reversal. AB - Vertebrate sex differentiation follows a conserved suite of developmental events: the bipotential gonads differentiate and shortly thereafter sex specific traits become dimorphic. However, this may not apply to squamates, a diverse vertebrate lineage comprising of many species with thermosensitive sexual development. Of the three species with data on the relative timing of gonad differentiation and genital dimorphism, the females of two (Niveoscincus ocellatus and Barisia imbricata) exhibit a phase of temporary pseudohermaphroditism or TPH (gonads have differentiated well before genital dimorphism). We report a third example of TPH in Pogona vitticeps, an agamid with temperature-induced male to female sex reversal. These findings suggest that for female squamates, genital and gonad development may not be closely synchronised, so that TPH may be common. We further observed a high frequency of ovotestes, a usually rare gonadal phenotype characterised by a mix of male and female structures, exclusively associated with temperature-induced sex reversal. We propose that ovotestes are evidence of a period of antagonism between male and female sex-determining pathways during sex reversal. Female sexual development in squamates is considerably more complex than has been appreciated, providing numerous avenues for future exploration of the genetic and hormonal cues that govern sexual development. PMID- 30291277 TI - Mathematical Modeling and Analyses of Interspike-Intervals of Spontaneous Activity in Afferent Neurons of the Zebrafish Lateral Line. AB - Without stimuli, hair cells spontaneously release neurotransmitter leading to spontaneous generation of action potentials (spikes) in innervating afferent neurons. We analyzed spontaneous spike patterns recorded from the lateral line of zebrafish and found that distributions of interspike intervals (ISIs) either have an exponential shape or an "L" shape that is characterized by a sharp decay but wide tail. ISI data were fitted to renewal-process models that accounted for the neuron refractory periods and hair-cell synaptic release. Modeling the timing of synaptic release using a mixture of two exponential distributions yielded the best fit for our ISI data. Additionally, lateral line ISIs displayed positive serial correlation and appeared to exhibit switching between faster and slower modes of spike generation. This pattern contrasts with previous findings from the auditory system where ISIs tended to have negative serial correlation due to synaptic depletion. We propose that afferent neuron innervation with multiple and heterogenous hair-cells synapses, each influenced by changes in calcium domains, can serve as a mechanism for the random switching behavior. Overall, our analyses provide evidence of how physiological similarities and differences between synapses and innervation patterns in the auditory, vestibular, and lateral line systems can lead to variations in spontaneous activity. PMID- 30291278 TI - Phenology determines the robustness of plant-pollinator networks. AB - Plant-pollinator systems are essential for ecosystem functioning, which calls for an understanding of the determinants of their robustness to environmental threats. Previous studies considering such robustness have focused mostly on species' connectivity properties, particularly their degree. We hypothesized that species' phenological attributes are at least as important as degree as determinants of network robustness. To test this, we combined dynamic modeling, computer simulation and analysis of data from 12 plant-pollinator networks with detailed information of topology of interactions as well as species' phenology of plant flowering and pollinator emergence. We found that phenological attributes are strong determinants of network robustness, a result consistent across the networks studied. Plant species persistence was most sensitive to increased larval mortality of pollinators that start earlier or finish later in the season. Pollinator persistence was especially sensitive to decreased visitation rates and increased larval mortality of specialists. Our findings suggest that seasonality of climatic events and anthropic impacts such as the release of pollutants is critical for the future integrity of terrestrial biodiversity. PMID- 30291279 TI - CCDC114 is mutated in patient with a complex phenotype combining primary ciliary dyskinesia, sensorineural deafness, and renal disease. AB - Ciliopathies-are widely recognized and associated with a wide variety of developmental and degenerative disorders. Most cilia-related diseases have renal manifestation, and there is a cross- overlapping relationship between gene mutations and cilia disease. Here, we investigated the clinical and pathological manifestation of a rare disease patient. We present the case of a 15-year-old child with dysplasia and multiple-organ damage who was initially diagnosed with nephrotic syndrome. The patient's kidney disease progressed to renal failure and received hemodialysis 10 months after renal biopsy. The individual presented primary ciliary dyskinesia (PCD) and additional symptoms including sensorineural deafness, kidney dysplasia, severe kidney function loss, and congenital heart disease which potentially linked to primary cilia deficiency. Cilia immunofluorescence of renal tissue showed a decrease in the number of cilium of the patient compared to the normal kidney. We identified a site mutation in CCDC114 (NM_144577 exon7 c. 596Ca T p. Ala199Val) by whole-exon sequences. We found that CCDC114 located at the basal body at cilia and the knockdown of CCDC114 could affect the occurrence of cilia in hRPE1 cells. The previous study of CCDC114 mainly lies in the motile cilia, and this study found that its impact on primary cilia thus broadened the understanding of overlapping function of different types of cilia. PMID- 30291280 TI - Evidence of a Causal Role for mid-Ventrolateral Prefrontal Cortex Based Functional Networks in Retrieving High-Fidelity Memory. AB - Functional neuroimaging studies have implicated regions of both ventrolateral prefrontal cortex (VLPFC) and angular gyrus in processes associated with retrieving goal-relevant information, which increases the fidelity and richness of long-term memory (LTM). To further investigate the roles of these cortical regions as nodes in functional networks with memory regions of the medial temporal lobe (MTL), we used fMRI-guided, 1 Hz repetitive transcranial magnetic stimulation (rTMS) to perturb normal neuronal function. The aim was to test the causal roles of left mid-VLPFC and left angular gyrus (AG) in MTL-VLPFC-parietal networks that have been associated with high-fidelity memory retrieval. rTMS treatments were administered immediately before blocks in an old/new recognition test, which was based on a mnemonic similarity task requiring discrimination of previously studied pictures of common objects. Capability for mnemonic discrimination was evaluated after each of three conditions: placebo control (rTMS at somatosensory cortex), mid-VLPFC target (rTMS at left pars triangularis) and parietal target (rTMS at left AG). The results showed the effect of rTMS perturbation of mid-VLPFC diminished subsequent discrimination-based memory performance, relative to placebo control, and no significant effect of perturbation of AG. These findings show a causal role for functional networks with left mid-VLPFC in high-fidelity retrieval. PMID- 30291281 TI - Relationship between Ocular Deviation and Visual Function in Retinitis Pigmentosa. AB - In retinitis pigmentosa (RP), peripheral visual-field loss starts in early stages, whereas central vision loss occurs in advanced stages. Sensory strabismus gradually occurs in RP. We investigated the relationship between ocular deviation and visual function and explored for sensory strabismus risk factors in 119 consecutive patients with RP at various stages. We assessed ocular deviation at far and near distances, that is the central visual field, using the mean deviation (MD) value and visual acuity (VA), and the residual binocular field area, using Goldmann perimetry (GP), in 33 patients. The horizontal ocular deviation at near distance was >10 degrees in 30% patients and correlated with residual visual function. Although there was no effective cut-off value for central visual function, a cut-off residual GP area of 40 cm2 distinguished patients with a larger from those with a smaller horizontal ocular deviation at far distance (P = 0.04). Our findings suggest that visual function is negatively associated with ocular deviation in patients with RP and that the sensory strabismus risk is relatively high for patients with a binocular visual field <40 cm2. Thus, screening for ocular alignment may be necessary for patients with RP associated severe vision loss as part of their comprehensive care. PMID- 30291282 TI - Genome-wide methylation analysis identifies ELOVL5 as an epigenetic biomarker for the risk of type 2 diabetes mellitus. AB - Genome-wide DNA methylation has been implicated in complex human diseases. Here, we identified epigenetic biomarkers for type 2 diabetes (T2D) underlying obesogenic environments. In a blood-based DNA methylation analysis of 11 monozygotic twins (MZTW) discordant for T2D, we discovered genetically independent candidate methylation sites. In a follow-up replication study (17 MZTW pairs) for external validation, we replicated the T2D-association at a novel CpG signal in the ELOVL fatty acid elongase 5 (ELOVL5) gene specific to T2D discordant MZTW. For concordant DNA methylation signatures in tissues, we further confirmed that a CpG site (cg18681426) was associated with adipogenic differentiation between human preadipocytes and adipocytes isolated from the same biopsy sample. In addition, the ELOVL5 gene was significantly differentially expressed in adipose tissues from unrelated T2D patients and in human pancreatic islets. Our results demonstrate that blood-derived DNA methylation is associated with T2D risk as a proxy for cumulative epigenetic status in human adipose and pancreatic tissues. Moreover, ELOVL5 expression was increased in cellular and mouse models of induced obesity-related diabetes. These findings may provide new insights into epigenetic architecture by uncovering methylation-based biomarkers. PMID- 30291283 TI - Formation of massive iron deposits linked to explosive volcanic eruptions. AB - The genetic link between magmas and ore deposit formation is well documented by studies of fossil hydrothermal systems associated with magmatic intrusions at depth. However, the role of explosive volcanic processes as active agents of mineralization remains unexplored owing to the fact that metals and volatiles are released into the atmosphere during the eruption of arc volcanoes. Here, we draw on observations of the uniquely preserved El Laco iron deposit in the Central Andes to shed new light on the metallogenic role of explosive volcanism that operates on a global scale. The massive magnetite (Fe3O4) ore bodies at El Laco have surface structures remarkably similar to basaltic lava flows, stimulating controversy about their origin. A long-standing debate has endured because all proposed models were constructed based exclusively on samples collected from surface outcrops representing the uppermost and most altered portion of the deposit. We overcome this sampling bias by studying samples retrieved from several drill cores and surface outcrops. Our results reveal complex lithological, textural and geochemical variations characterized by magmatic-like features and, most notably, a systematic increase in titanium concentration of magnetite with depth that account for an evolving system transitioning from purely magmatic to magmatic-hydrothermal conditions. We conclude that El Laco, and similar deposits worldwide, formed by a synergistic combination of common magmatic processes enhanced during the evolution of caldera-related explosive volcanic systems. PMID- 30291284 TI - The DNA Repair Protein OGG1 Protects Against Obesity by Altering Mitochondrial Energetics in White Adipose Tissue. AB - Obesity and related metabolic pathologies represent a significant public health concern. Obesity is associated with increased oxidative stress that damages genomic and mitochondrial DNA. Oxidatively-induced lesions in both DNA pools are repaired via the base-excision repair pathway, initiated by DNA glycosylases such as 8-oxoguanine DNA glycosylase (OGG1). Global deletion of OGG1 and common OGG1 polymorphisms render mice and humans susceptible to metabolic disease. However, the relative contribution of mitochondrial OGG1 to this metabolic phenotype is unknown. Here, we demonstrate that transgenic targeting of OGG1 to mitochondria confers significant protection from diet-induced obesity, insulin resistance, and adipose tissue inflammation. These favorable metabolic phenotypes are mediated by an increase in whole body energy expenditure driven by specific metabolic adaptations, including increased mitochondrial respiration in white adipose tissue of OGG1 transgenic (Ogg1Tg) animals. These data demonstrate a critical role for a DNA repair protein in modulating mitochondrial energetics and whole body energy balance. PMID- 30291285 TI - Contribution of SPI-1 bistability to Salmonella enterica cooperative virulence: insights from single cell analysis. AB - Salmonella enterica pathogenicity island 1 (SPI-1) is a gene cluster that encodes a type III secretion system and effectors involved in epithelial cell invasion. SPI-1 undergoes bistable expression, with concomitant formation of SPI-1ON and SPI-1OFF lineages. This study describes single cell analysis of SP1-1 bistability and epithelial cell invasion, and reports the unsuspected observation that optimal invasion of epithelial cells requires the presence of both SPI-1ON and SPI-1OFF subpopulations. The contribution of SPI-1OFF cells to optimal invasion may rely on their ability to invade epithelial cells if a SPI-1ON subpopulation is present. In fact, Salmonella SPI-1 mutants are also able to invade epithelial cells in the presence of SPI-1ON Salmonellae, a phenomenon described in the 1990's by Galan and co-workers. Invasion by SPI-1OFF cells does not seem to involve a diffusible factor. A small number of SPI-1ON cells is sufficient to endow the bacterial population with invasion capacity, a feature that may permit host colonization regardless of the bottlenecks encountered by Salmonella populations inside animals. PMID- 30291286 TI - Alteration of Serum Free Fatty Acids are Indicators for Progression of Pre leukaemia Diseases to Leukaemia. AB - Acute Leukaemia (AL) is a neoplasm of WBCs (white blood cells). Being an important class of metabolites, alteration in free fatty acids (FFAs) levels play a key role in cancer development and progression. As they involve in cell signaling, maintain membrane integrity, regulate homeostasis and effect cell and tissue functions. Considering this fact, a comprehensive analysis of FFAs was conducted to monitor their alteration in AL, pre-leukaemic diseases and healthy control. Fifteen FFAs were analyzed in 179 serum samples of myelodysplastic syndrome (MDS), aplastic anemia (APA), acute lymphoblastic leukaemia (ALL), acute myeloid leukaemia (AML) and healthy control using gas chromatography-multiple reaction monitoring-mass spectrometry (GC-MRM-MS). A multivariate statistical method of random forest (RF) was employed for chemometric analysis. Serum level of two FFAs including C18:0 and C14:0 were found discriminative among all five groups, and between ALL and AML, respectively. Moreover, C14:0 was identified as differentiated FFAs for systematic progression of pre-leukaemic conditions towards AML. C16:0 came as discriminated FFAs between APA and MDS/AML. Over all it was identified that FFAs profile not only become altered in leukaemia but also in pre-leukaemic diseases. PMID- 30291287 TI - Enhancement of PCR Sensitivity and Yield Using Thiol-modified Primers. AB - Various additives can enhance the quality of PCR amplification, but these generally require considerable optimization to achieve peak performance. Here, we demonstrate that the use of thiol-modified primers can enhance both PCR sensitivity and yield. In experiments with V. parahaemolyticus genomic DNA, this primer modification enhances PCR sensitivity by more than 100-fold, with accompanying improvements in amplicon yield. Then, an artificial plasmid with the same primer binding regions and different internal amplification sequence was designed. The result showed that the amplification also be improved by using the same thiol-modified primers. It indicated the enhancement was not caused by the effect of the thiol-modified primers on the second structure of amplification sequence. Subsequent experiments demonstrate that the effects of this modification are potentially due to altered interaction between the primers and proteins in the reaction mixture. Amplification with thiol-modified primers was strongly inhibited by the presence of extraneous proteins relative to standard DNA primers, which indicates that thiol-modified primers may be inhibited due to interaction with these proteins. In contaminant-free reactions, however, the thiol-modified primers might interact more strongly with DNA polymerase, which could in turn improve PCR amplification. PMID- 30291288 TI - Energy barriers at grain boundaries dominate charge carrier transport in an electron-conductive organic semiconductor. AB - Semiconducting organic films that are at the heart of light-emitting diodes, solar cells and transistors frequently contain a large number of morphological defects, most prominently at the interconnects between crystalline regions. These grain boundaries can dominate the overall (opto-)electronic properties of the entire device and their exact morphological and energetic nature is still under current debate. Here, we explore in detail the energetics at the grain boundaries of a novel electron conductive perylene diimide thin film. Via a combination of temperature dependent charge transport measurements and ab-initio simulations at atomistic resolution, we identify that energetic barriers at grain boundaries dominate charge transport in our system. This novel aspect of physics at the grain boundary is distinct from previously identified grain-boundary defects that had been explained by trapping of charges. We furthermore derive molecular design criteria to suppress such energetic barriers at grain boundaries in future, more efficient organic semiconductors. PMID- 30291290 TI - Analysis of coupling between magnetic dipoles enhanced by metasurfaces for wireless power transfer efficiency improvement. AB - In this paper, we investigate the possibility of improving efficiency in non radiative wireless power transfer (WPT) using metasurfaces embedded between two current varying coils and present a complete theoretical analysis of this system. We use a point-dipole approximation to calculate the fields of the coils. Based on this method, we obtain closed-form and analytical expressions which would provide basic insights into the possibility of efficiency improvement with metasurface. In our analysis, we use the equivalent two sided surface impedance model to analyze the metasurface and to show for which equivalent surface impedance the WPT efficiency will be maximized at the design frequency. Then, to validate our theory, we perform a full-wave simulation for analyzing a practical WPT system, including two circular loop antennas at 13.56 MHz. We then design a metasurface composed of single-sided CLSRRs to achieve a magnetic lensing based on the calculated equivalent surface impedance. The analytical results and full wave simulations indicated non-radiative WPT efficiency improvement due to amplifying the near evanescent field which can be achieved through inserting the proposed metasurface. PMID- 30291289 TI - Recommendations for improving accuracy of gene expression data in bone and cartilage tissue engineering. AB - Autogenous tissue grafting remains the gold standard in the treatment of critical sized bone and certain cartilage defects, while the translation of tissue engineered osteogenesis or chondrogenesis from the lab bench into clinical practice, utilizing natural or synthetic biomimetic devices, remains challenging. One of the crucial underestimated reasons for non-translatability could be the imprecision and inconsistency of generated gene expression profiles, utilizing improperly optimized and standardized quantitative gene assays. Utilizing GeNorm for downstream qRT-PCR applications, the stability of reference genes in relation to optimal cDNA amounts was assessed on human bone marrow-derived mesenchymal and adipose-derived stem cells neat and made to differentiate into chondrocytes including normal human derived chondrocytes and muscle tissue from rats. Results showed that reference genes can vary substantially across separately and/or combined cell lines and/or tissue types including treatment parameters. The recommendations to all bone and cartilage tissue engineers utilizing qRT-PCR is not to assume that reference gene stability and quantity remain conserved across cell lines or tissue types but to always determine, for each new experiment, the stability and normalization quantity of reference genes anew. PMID- 30291291 TI - First assessment of the comparative toxicity of ivermectin and moxidectin in adult dung beetles: Sub-lethal symptoms and pre-lethal consequences. AB - Among macrocyclic lactones (ML), ivermectin (IVM) and moxidectin (MOX) potentially affect all Ecdysozoan species, with dung beetles being particularly sensitive. The comparative effects of IVM and MOX on adult dung beetles were assessed for the first time to determine both the physiological sub-lethal symptoms and pre-lethal consequences. Inhibition of antennal response and ataxia were tested as two intuitive and ecologically relevant parameters by obtaining the lowest observed effect concentration (LOEC) values and interpolating other relevant toxicity thresholds derived from concentration-response curves (IC50, as the concentration of each ML where the antennal response is inhibited by half; and pLC50, as the quantity of ingested ML where partial paralysis was observed by half of treated individuals) from concentration-response curves. Both sub-lethal and pre-lethal symptoms obtained in this study coincided in that IVM was six times more toxic than MOX for adult dung beetles. Values of LOEC, IC50 and pLC50 obtained for IVM and MOX evaluated in an environmental context indicate that MOX, despite needing more time for tis elimination in the faeces, would be twice as harmful to dung beetles as IVM. This approach will be valuable to clarify the real impact of MLs on dung beetle health and to avoid the subsequent environmental consequences.

PMID- 30291293 TI - Ankyrin Repeat Domain 1 Overexpression is Associated with Common Resistance to Afatinib and Osimertinib in EGFR-mutant Lung Cancer. AB - Overcoming acquired resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) is critical in combating EGFR-mutant non-small cell lung cancer (NSCLC). We tried to construct a novel therapeutic strategy to conquer the resistance to second-and third-generation EGFR-TKIs in EGFR-positive NSCLC patients. We established afatinib- and osimertinib-resistant lung adenocarcinoma cell lines. Exome sequencing, cDNA array and miRNA microarray were performed using the established cell lines to discover novel therapeutic targets associated with the resistance to second-and third-generation EGFR-TKIs. We found that ANKRD1 which is associated with the epithelial-mesenchymal transition (EMT) phenomenon and anti-apoptosis, was overexpressed in the second-and third generation EGFR-TKIs-resistant cells at the mRNA and protein expression levels. When ANKRD1 was silenced in the EGFR-TKIs-resistant cell lines, afatinib and osimertinib could induce apoptosis of the cell lines. Imatinib could inhibit ANKRD1 expression, resulting in restoration of the sensitivity to afatinib and osimertinib of EGFR-TKI-resistant cells. In EGFR-mutant NSCLC patients, ANKRD1 was overexpressed in the tumor after the failure of EGFR-TKI therapy, especially after long-duration EGFR-TKI treatments. ANKRD1 overexpression which was associated with EMT features and anti-apoptosis, was commonly involved in resistance to second-and third-generation EGFR-TKIs. ANKRD1 inhibition could be a promising therapeutic strategy in EGFR-mutant NSCLC patients. PMID- 30291294 TI - Variability of crossing phase in older people with Parkinson's disease is dependent of obstacle height. AB - Our aim was investigating variability in spatiotemporal parameters and kinetics of obstacle avoidance steps of different height obstacles in people with Parkinson's disease (PD) and healthy older people. Twenty-eight participants have included (15 PD - stage disease: 2.1 +/- 0.4 pts) and 13 healthy older people (control group). Each subject performed 10 trials of the following tasks: low obstacle, intermediate obstacle and high obstacle. The presentation order was randomized by block for each condition and participant. The spatiotemporal parameters was collected by GAITRite. An optoelectronic system (Optotrak Northern Digital Inc.) with 100 Hz of frequency was used to collect obstacle parameters. The kinect parameters (propulsion impulse and braking impulse) were acquire through two force plates (AccuGait), with a frequency of acquisition 200 Hz. Intersteps variability was calculated throughout mean values, standard deviation and coefficient of variation of two obstacle avoidance steps for each trial. PD group presented greater variability than control group on vertical and horizontal distances to the obstacle. Obstacle height did not change kinect's parameters for both groups. The combination of task complexity (obstacle height) and disease impairments (gait alteration, loss of balance, etc) contributing for greater variability of Parkinson's group. Besides, low obstacle and high obstacle seem to exacerbate variability of distance between obstacle and foot. PMID- 30291295 TI - Empagliflozin Ammeliorates High Glucose Induced-Cardiac Dysfuntion in Human iPSC Derived Cardiomyocytes. AB - Empagliflozin, a sodium-glucose co-transporter (SGLT) inhibitor, reduces heart failure and sudden cardiac death but the underlying mechanisms remain elusive. In cardiomyocytes, SGLT1 and SGLT2 expression is upregulated in diabetes mellitus, heart failure, and myocardial infarction. We hypothesise that empagliflozin exerts direct effects on cardiomyocytes that attenuate diabetic cardiomyopathy. To test this hypothesis, cardiomyocytes derived from human induced pluripotent stem cells (hiPSCs) were used to test the potential effects of empagliflozin on neutralization of cardiac dysfunction induced by diabetic-like cultures. Our results indicated that insulin-free high glucose culture significantly increased the size of and NPPB, SGLT1 and SGLT2 expression of hiPSC-derived cardiomyocytes. In addition, high glucose-treated hiPSC-derived cardiomyocytes exhibited reduced contractility regardless of the increased calcium transient capacity. Interestingly, application of empagliflozin before or after high glucose treatment effectively reduced the high glucose-induced cardiac abnormalities. Since application of empagliflozin did not significantly alter viability or glycolytic capacity of the hiPSC-derived cardiomyocytes, it is plausible that empagliflozin exerts its effects via the down-regulation of SGLT1, SGLT2 and GLUT1 expression. These observations provide supportive evidence that may help explain its unexpected benefit observed in the EMPA-REG trial. PMID- 30291296 TI - Splenectomy modulates early immuno-inflammatory responses to trauma-hemorrhage and protects mice against secondary sepsis. AB - In polytrauma patients, the impact of splenectomy is equivocal, ranging from negative to protective. We investigated the impact of splenectomy on immune responses in the 1st-hit polytrauma alone and on survival in the post-traumatic sepsis (2nd hit). Female BALB/c mice underwent polytrauma (1st hit) consisting of either a) TH: femur fracture, hemorrhagic shock or b) TSH: splenectomy, femur fracture, hemorrhagic shock. Additionally, the polytrauma hit was followed by cecal ligation and puncture (CLP) 48 h later and compared to CLP alone. Splenectomy improved the 28-day survival in secondary sepsis to 92% (from 62%), while TH lowered it to 46% (p < 0.05). The improved survival was concurrent with lower release of inflammatory cytokines (IL-6, CXCL-1, MCP-1) and increase of C5a post-CLP. In the polytrauma hit alone, TSH induced stronger neutrophilia (1.9 fold) and lymphocytosis (1.7 fold) when compared to TH mice. Moreover, TSH resulted in a 41% rise of regulatory T-cells and reduced the median fluorescence intensity of MHC-2 on monocytes by 55% within 48 h (p < 0.05). Conversely, leukocyte phagocytic capacity was significantly increased by 4-fold after TSH despite a similar M1/M2 macrophage profile in both groups. Summarizing, splenectomy provoked both immuno-suppressive and immuno-stimulatory responses but was life-saving in secondary sepsis. Additionally, the polytrauma components in 2 hit models should be tested for their effects on outcome; the presumed end-effect of the 1st hit solely based on the common immuno-inflammatory parameters could be misleading. PMID- 30291297 TI - A new pharmacokinetic model for 90Y-ibritumomab tiuxetan based on 3-dimensional dosimetry. AB - Monoclonal antibodies (mAbs) are key components in several therapies for cancer and inflammatory diseases but current knowledge of their clinical pharmacokinetics and distribution in human tissues remains incomplete. Consequently, optimal dosing and scheduling in clinics are affected. With sequential radiolabeled mAb-based imaging, radiation dosing in tissues/organs can be calculated to provide a better assessment of mAb concentrations in tissues. This is the first pharmacokinetic model of 90Y-Ibritumomab tiuxetan (90Y-IT) in humans to be described, based on three-dimensional (3D) dosimetry using single photon emission computed-tomography coupled with computed-tomography. 19 patients with follicular lymphoma were treated initially with 90Y-IT in the FIZZ trial. Based on a compartmental approach individualising the vascular compartment within studied organs, this study proposes a reliable pharmacokinetic (PK) five compartment model replacing the currently used two-compartment model and constitutes a new direction for further research. This model provides exchange constants between the different tissues, Area Under the Curve of 111In-IT in blood (AUC) and Mean Residence Time (MRT) that have not been reported so far for IT. Finally, the elimination process appears to occur in a compartment other than the liver or the spleen and suggests the metabolism of mAbs may take place mainly on the vascular compartment level.

AB - Climate impacts on marine ecosystems may be exacerbated by other, more local stressors interacting synergistically, such as pollution and overexploitation of marine resources. The reduction of these human stressors has been proposed as an achievable way of retaining ecosystems within a "safe operating space" (SOS), where they remain resilient to ongoing climate change. However, the operability of an SOS requires a thorough understanding of the spatial distribution of these climate and human impacts. Using the Mediterranean Sea as a case study, we illustrate the spatial congruence between climate and human stressors impacting this iconic "miniature ocean" synergistically. We use long-term, spatially explicit information on the distribution of multiple stressors to identify those highly impacted marine areas where human stressors should be prioritized for management if the resilience to climate impacts is to be maintained. Based on our spatial analysis, we exemplify how the management of an essential supporting service (seafood provision) and the conservation of a highly impacted Mediterranean sub-region (the Adriatic Sea) may benefit from the SOS framework.

AB - We perform ab initio investigations of the bulk and surface band structures of LaSb and LaBi and resolve the existing disagreements about the topological property of LaSb, considering LaBi as a reference. We examine the bulk band structure for band inversion, along with the stability of surface Dirac cones (if any) to time-reversal-preserving perturbations, as a strong diagnostic test for determining the topological character of LaSb, LaBi and LaSb-LaBi multilayer. A detailed ab initio investigation of a multilayer consisting of alternating unit cells of LaSb and LaBi shows the presence of band inversion in the bulk and a massless Dirac cone on the (001) surface, which remains stable under the influence of time-reversal-preserving perturbations, thus confirming the topologically non-trivial nature of the multilayer in which the electronic properties can be tailored as per requirement.

PMID- 30291307 TI - Gut dysbiosis is associated with the reduced exercise capacity of elderly patients with hypertension. AB - Hypertension is a global health issue, and a reduced exercise capacity is unavoidable for older people. According to recent clinical studies, the intestinal microbiota play a crucial role in the pathogenesis of many human diseases. We investigated whether specific alterations in the gut microbiota contribute to the reduced exercise capacity of elderly patients with hypertension. This study enrolled 56 subjects, and all patients performed a cardiopulmonary exercise test and underwent fecal bacteria sequencing (16 s ribosomal RNA V4 region). According to peak oxygen uptake values, patients were divided into three groups (Weber A = 19, Weber B = 20, and Weber C = 17). The alpha diversity was not significantly different among the three groups. Regarding the beta diversity, Weber A samples were separate from the other two groups in the nonmetric multidimensional scaling ordination plot (ANOSIM pairwise comparisons generated an R > 0.5; p < 0.05). The abundance of Betaproteobacteria, Burkholderiales, Alcaligenaceae, Faecalibacterium and Ruminococcaceae was diminished in subjects with a reduced exercise capacity (LDA score > 4.0). Escherichia coli are a primary producer of trimethylamine and inflammation in the human gut, and the abundance of this bacteria was increased in patients with a reduced exercise capacity (LDA score > 4.0). On the other hand, Lachnospiraceae Eubacterium_hallii_group, Lachnospiraceae-Lachnoclostridium, Lachnospiraceae Blautia-Ruminococcus_sp__5_1_39BFAA, and Ruminococcaceae-Faecalibacterium belong to the order Clostridiales that are likely to produce short-chain fatty acids (LDA score > 4.0), and some of these species were enriched in the Weber B or Weber C group in multiple comparisons. Our data pointed to an altered gut microbiota as a potential contributor to the pathogenesis and progression of the reduced exercise capacity of elderly patients with hypertension.

PMID- 30291312 TI - Replication and novel analysis of age and sex effects on the neurologic and functional value of each spinal segment in the US healthcare setting. AB - STUDY DESIGN: Replication of previously developed prognostic model. OBJECTIVES: In motor complete injuries at admission to rehabilitation, perform; (1) replication analyses of the relationships between ISNCSCI motor level and motor scores and SCIM and (2) novel analyses to determine if age and/or sex moderate relationship between neurological impairment and function. SETTING: Admission to initial inpatient rehabilitation in the United States. METHODS: Post-Hoc analyses of data collected as part of a separate study. Replication analyses: (1) Pearson's correlation assessed relationship strength between neurologic impairment and function. (2) Multiple linear regression assessed if center or age influenced functional outcome. Novel analyses: (1) Moderated multiple regression assessed if age and/or sex moderated the lesion level-function relationship. RESULTS: Of the 406 datasets, 161 were motor complete injuries, and included in the analyses. Median time post injury at admission to rehabilitation was 19 days. Our replication analyses confirmed the neurologic and functional value of each spinal segment reported by the EM-SCI group (all p <= 0.018). We failed to confirm their reported age effect (p = 0.05) and non-effect of center (p = 0.037). Our novel analyses indicated that age coded as above/below 50 moderated the relationship between neurologic impairment and function (p = 0.038) in cervical injuries only, but that age coded as above/below 35 (all p >= 0.510) and sex (all p >= 0.465) did not. CONCLUSIONS: The neurological and functional value of each segment is consistent across very different healthcare settings in early and late sub-acute stages and minimally impacted by age and sex. Differences related to centers and age may confound efficacy trials. SPONSORSHIP: The Miami Project to Cure Paralysis; The Craig H. Neilsen Foundation (83492).

AB - There is an urgent need to develop improved, physiologically-relevant in vitro models of airway epithelia with which to better understand the pathological processes associated with infection, allergies and toxicological insults of the respiratory tract of both humans and domesticated animals. In the present study, we have characterised the proliferation and differentiation of primary bovine bronchial epithelial cells (BBECs) grown at an air-liquid interface (ALI) at three-day intervals over a period of 42 days from the introduction of the ALI. The differentiated BBEC model was highly representative of the ex vivo epithelium from which the epithelial cells were derived; a columnar, pseudostratified epithelium that was highly reflective of native airway epithelium was formed which comprised ciliated, goblet and basal cells. The hallmark defences of the respiratory tract, namely barrier function and mucociliary clearance, were present, thus demonstrating that the model is an excellent mimic of bovine respiratory epithelium. The epithelium was fully differentiated by day 21 post ALI and, crucially, remained healthy and stable for a further 21 days. Thus, the differentiated BBEC model has a three-week window which will allow wide-ranging and long-term experiments to be performed in the fields of infection, toxicology or general airway physiology. PMID- 30291313 TI - Cavernosal hydrogen sulfide levels are associated with nitric oxide and hemeoxygenase levels in diabetic rats. AB - Penile erection is a neuromuscular event modulated by psyche, hormones as well as neurotransmitters. This pre-clinical study aimed to assess hydrogen sulfide (H2S) relationship with nitric oxide (NO) and hemeoxygenase (HO) in the cavernous tissues of diabetic rats. Overall, 90 adult male rats were investigated (6 groups, n = 15 each). They were subdivided into the following groups; untreated rats, rats treated with H2S donor/inhibitor, induced diabetic rats, diabetic rats treated with H2S donor/inhibitor. At the 6th week, the rats were killed to assess cavernous tissue cGMP, NO, H2S, HO enzyme activity levels. The rats treated with H2S donor showed increased mean cavernous tissue cGMP, NO, H2S, and HO enzyme activity levels whereas induced diabetic rats and rats treated with H2S inhibitor showed significant decreases in these parameters compared with the untreated rats. On the other hands, diabetic rats treated with H2S donor showed elevated mean cavernous tissue cGMP, NO, H2S, and HO enzyme activity levels whereas diabetic rats treated with H2S inhibitor showed significant decreases in these parameters compared with diabetic rats. Cavernous tissue H2S levels exhibited significant positive correlations with the cavernous tissue levels cGMP, NO, and HO enzyme activity levels. From these results, it could be concluded that cavernous tissues H2S plays a role of male sexual health by affecting cavernous tissues NO and HO enzyme activity in general and in diabetics in particular.

PMID- 30291316 TI - Genetic Variations Linked to Hepatocellular Carcinoma: Personalized Medicine Takes a Step Forward. AB - : There are strong associations between candidate genetic polymorphisms associated with intrahepatocyte lipid droplet accumulation and the development of cirrhosis, via a common sequence in which lipid accumulation is followed by chronic inflammatory injury and fibrogenesis. Hepatocellular carcinoma (HCC) has also been linked to genetic polymorphisms associated with intracellular lipid trafficking, although, as shown in the present study, not all the candidate polymorphisms implicated in fibrogenesis are also tied to HCC. Genetic analysis may identify at-risk persons who would most benefit from modifying life-style factors linked to cirrhosis and HCC, and also persons most likely to benefit from HCC surveillance. PMID- 30291317 TI - Lifestyle interventions to prevent cognitive impairment, dementia and Alzheimer disease. AB - Research into dementia prevention is of paramount importance if the dementia epidemic is to be halted. Observational studies have identified several potentially modifiable risk factors for dementia, including hypertension, dyslipidaemia and obesity at midlife, diabetes mellitus, smoking, physical inactivity, depression and low levels of education. Randomized clinical trials are needed that investigate whether interventions targeting these risk factors can reduce the risk of cognitive decline and dementia in elderly adults, but such trials are methodologically challenging. To date, most preventive interventions have been tested in small groups, have focused on a single lifestyle factor and have yielded negative or modest results. Given the multifactorial aetiology of dementia and late-onset Alzheimer disease, multidomain interventions that target several risk factors and mechanisms simultaneously might be necessary for an optimal preventive effect. In the past few years, three large multidomain trials (FINGER, MAPT and PreDIVA) have been completed. The FINGER trial showed that a multidomain lifestyle intervention can benefit cognition in elderly people with an elevated risk of dementia. The primary results from the other trials did not show a statistically significant benefit of preventive interventions, but additional analyses among participants at risk of dementia showed beneficial effects of intervention. Overall, results from these three trials suggest that targeting of preventive interventions to at-risk individuals is an effective strategy. This Review discusses the current knowledge of lifestyle-related risk factors and results from novel trials aiming to prevent cognitive decline and dementia. Global initiatives are presented, including the World Wide FINGERS network, which aims to harmonize studies on dementia prevention, generate high quality scientific evidence and promote its implementation. PMID- 30291318 TI - Low rate of necrotizing enterocolitis in extremely low birth weight infants using a hospital-based preterm milk bank. AB - OBJECTIVE: We examined the effect of two strategies to prevent necrotizing enterocolitis (NEC) in extremely low birth weight (ELBW) infants-adherence to a standardized feeding protocol and use of a hospital-based milk bank to provide exclusive preterm human milk feedings. STUDY DESIGN: We conducted a single-center observational study from 2010 to 2015. Infants received preterm human milk, initially trophic feeds from days 7 to 14 after birth, followed by advancement of 15 mL/kg/day to reach a goal of 180 mL/kg/day. Fortification was used selectively for weight gain < 15 g/kg/day. We determined the incidence of NEC, other morbidities, and growth. RESULTS: The cohort included 398 ELBW infants who survived to day 14 without congenital anomalies. Mean gestational age was 26.2 +/ 1.9 weeks. Maternal milk was used as the sole feeding in 62% of infants; preterm donor milk was used solely or as supplement in 29%. Full feeds were reached at a median of 27 (IQR 23, 33) days. Four infants (1%) developed NEC. CONCLUSION: Use of standardized feedings with a hospital-based milk bank is associated with an incidence of NEC lower than previously reported. PMID- 30291319 TI - Hyaline membrane disease (HMD): an historical and Oslerian perspective. AB - Hyaline membrane disease (HMD) offers an illustration of a disease discovered during the lifetime of William Osler and effectively treated in the twentieth century-the perspective that suggests that there was a straightforward progressive identification of the disease process, a discovery of the underlying biochemical agent responsible for the pathophysiology, and the pharmacological refinement of that agent to be used to treat the disease is illusory. By reviewing the timeline from the earliest pathological description of what was to be later termed HMD to the discovery of surfactant and its impact on infant mortality, this narrative will demonstrate how various random historical events served to affect the progress of developing a treatment for HMD; how the marked reduction in deaths due to HMD may have set the stage for unrealistic expectations; and how the humanities have warned us of the potential for excessive optimism in our understanding of nature. PMID- 30291320 TI - Does inhaled budesonide for bronchopulmonary dysplasia affect the neurodevelopmental outcomes? PMID- 30291321 TI - Tidal volume monitoring during emergency neonatal transport. AB - OBJECTIVE: The study aim was to identify the frequency with which tidal volumes were achieved in a target range in infants requiring positive pressure ventilation on emergency transport. STUDY DESIGN: We performed a prospective observational study of infants requiring continued positive pressure ventilation during emergency transport after resuscitation and stabilization. Blindly recorded data were analyzed for percentage of breaths that were below range, in range, and above desired range of 4-6 mL/kg. RESULT: Fourteen patients were monitored during transport from the delivery room to the neonatal intensive care unit, and 15 patients were monitored during inter-facility transport. During delivery room transport, 21 and 7% of patients were in target range greater than 50 and 90% of the time, respectively. During inter-hospital transport, 60 and 7% of patients were in target range greater than 50 and 90% of the time, respectively. CONCLUSION: Clinical assessment of appropriate ventilation is difficult and often inaccurate during emergency neonatal transport. Improved monitoring of respiratory function to guide clinical status during transport is necessary. More investigation and implementation are urgently needed. PMID- 30291322 TI - Development of a points-based system for determining workload for a neonatology full-time equivalent. AB - Quantifying the workload for a hospital-based physician can be a challenge. We developed a novel approach to providing equity and flexibility for physicians working in a large system with heterogeneous clinical activities. In developing this points-based system, expected clinical work hours were calculated for a full time equivalent. A point value was assigned to each clinical service based upon the hours, complexity and intensity of the work. A hypothetical work schedule was created using the expected clinical hours and translated into points needed for a full-time clinician. Faculty appreciate the flexibility and feel appropriately valued and equitably paid. Our system serves as a recruitment tool and enables the division to better understand resource needs and predict the need for additional staff. Development of a point-based model for calculating clinical work has successfully created a homogeneous system to define and measure physician work expectations in a heterogeneous clinical environment. PMID- 30291323 TI - Mitochondrial pyruvate carrier 1 functions as a tumor suppressor and predicts the prognosis of human renal cell carcinoma. AB - Invasion and subsequent metastasis are major characteristics of malignant human renal cell carcinoma (RCC), though the mechanisms remain elusive. Mitochondrial pyruvate carrier (MPC), a key factor that controls pyruvate transportation in mitochondria, is frequently dysregulated in tumor cells and loss of MPC predicts poor prognosis in various types of cancer. However, the clinical relevance and functional significance of MPC in RCC remain to be elucidated. In this study, we investigated the expression of MPC1 and MPC2 in specimens from RCC patients and observed downregulation of MPC1, but not MPC2, in RCC tissues compared with adjacent non-cancerous tissue. Moreover, RCC patients with higher MPC1 expression exhibited longer overall survival rate than those with lower MPC1. Functionally, MPC1 suppressed the invasion of RCC cells in vitro and reduced the growth of RCC cells in vivo, possibly through inhibition of MMP7 and MMP9. Further studies revealed that loss of MPC1 was induced by hypoxia in RCC cells, and notably, MPC1 expression, was negatively correlated with HIF1alpha expression in RCC cells and patient samples. Taken together, our results identify anti-tumor function of MPC1 in RCC and revealed MPC1 as a novel prognostic biomarker to predict better patient survival. PMID- 30291324 TI - First trimester placental endothelial cells from pregnancies with abnormal uterine artery Doppler are more sensitive to apoptotic stimuli. AB - Failure of the placental capillary network to develop normally is associated with early onset fetal growth restriction (FGR) and pre-eclampsia (PE). Although the symptoms are observed at term, the problem begins in the first trimester. However, investigations at this clinically relevant time are hindered by difficulties in identifying earlystage pregnancies that are at risk of developing FGR/PE. Using uterine artery Doppler ultrasound in the first trimester as a proxy measure of poor placentation, we have identified pregnancies at increased risk of developing early onset FGR/PE. Placental endothelial cells (PEC) isolated from pregnancies at increased risk of developing FGR/PE grew more slowly and their basal rate of apoptosis was significantly higher than that seen in the normal group. The pro-apoptotic stimulus, TNFalpha, induced apoptosis in cells from both groups but this was significantly greater in the high risk group. TNF receptor expression was unaffected. Inhibition of nitric oxide (NO) production significantly increased the sensitivity of cells from the normal pregnancies to TNFalpha but not in the high risk group establishing a functional role for NO in this system. In conclusion, first trimester PEC from pregnancies at increased risk of developing early onset FGR/PE were inherently more sensitive to apoptotic stimuli and this was functionally linked to the synthesis of NO. This may contribute to the poor placental vascular development seen in on going pregnancies. PMID- 30291325 TI - The cofilin phosphatase slingshot homolog 1 restrains angiotensin II-induced vascular hypertrophy and fibrosis in vivo. AB - The dual specificity phosphatase slingshot homolog 1 (SSH1) contributes to actin remodeling by dephosphorylating and activating the actin-severing protein cofilin. The reorganization of the actin cytoskeleton has been implicated in chronic hypertension and the subsequent mechano-adaptive rearrangement of vessel wall components. Therefore, using a novel Ssh1-/- mouse model, we investigated the potential role of SSH1 in angiotensin II (Ang II)-induced hypertension, and vascular remodeling. We found that loss of SSH1 did not produce overt phenotypic changes and that baseline blood pressures as well as heart rates were comparable between Ssh1+/+ and Ssh1-/- mice. Although 14 days of Ang II treatment equally increased systolic blood pressure in both genotypes, histological assessment of aortic samples indicated that medial thickening was exacerbated by the loss of SSH1. Consequently, reverse-transcription quantitative PCR analysis of the transcripts from Ang II-infused animals confirmed increased aortic expression levels of fibronectin, and osteopontin in Ssh1-/- when compared to wild-type mice. Mechanistically, our data suggest that fibrosis in SSH1-deficient mice occurs by a process that involves aberrant responses to Ang II-induced TGFbeta1. Taken together, our work indicates that Ang II-dependent fibrotic gene expression and vascular remodeling, but not the Ang II-induced pressor response, are modulated by SSH1-mediated signaling pathways and SSH1 activity is protective against Ang II-induced remodeling in the vasculature. PMID- 30291326 TI - Single-mode, high-power, mid-infrared, quantum cascade laser phased arrays. AB - We demonstrate single-mode, 16-channel, optical phased arrays based on quantum cascade laser technology, with emission wavelengths around 4.8 um. The integrated device consists of a distributed feedback seed section, a highly-efficient tree array multi-mode interferometer power splitter, and a 16-channel amplifier array with a 4 degrees angled facet termination. With a single layer Y2O3 coating, the angled facet reflectivity is estimated to be less than 0.1% for suppressing amplifier self-lasing. A peak output power of 30 W is achieved with an emission spectrum narrower than 11 nm and a side mode suppression ratio over 25 dB. Far field distribution measurement result indicates a uniform phase distribution across the array output. Using the same phased array architecture, we also demonstrate single-mode 3.8 um QCL amplifier arrays with up to 20 W output power. PMID- 30291327 TI - Modeling microbial communities from atrazine contaminated soils promotes the development of biostimulation solutions. AB - Microbial communities play a vital role in biogeochemical cycles, allowing the biodegradation of a wide range of pollutants. The composition of the community and the interactions between its members affect degradation rate and determine the identity of the final products. Here, we demonstrate the application of sequencing technologies and metabolic modeling approaches towards enhancing biodegradation of atrazine-a herbicide causing environmental pollution. Treatment of agriculture soil with atrazine is shown to induce significant changes in community structure and functional performances. Genome-scale metabolic models were constructed for Arthrobacter, the atrazine degrader, and four other non atrazine degrading species whose relative abundance in soil was changed following exposure to the herbicide. By modeling community function we show that consortia including the direct degrader and non-degrader differentially abundant species perform better than Arthrobacter alone. Simulations predict that growth/degradation enhancement is derived by metabolic exchanges between community members. Based on simulations we designed endogenous consortia optimized for enhanced degradation whose performances were validated in vitro and biostimulation strategies that were tested in pot experiments. Overall, our analysis demonstrates that understanding community function in its wider context, beyond the single direct degrader perspective, promotes the design of biostimulation strategies. PMID- 30291328 TI - Pangenomic comparison of globally distributed Poribacteria associated with sponge hosts and marine particles. AB - Candidatus Poribacteria is a little-known bacterial phylum, previously characterized by partial genomes from a single sponge host, but never isolated in culture. We have reconstructed multiple genome sequences from four different sponge genera and compared them to recently reported, uncharacterized Poribacteria genomes from the open ocean, discovering shared and unique functional characteristics. Two distinct, habitat-linked taxonomic lineages were identified, designated Entoporibacteria (sponge-associated) and Pelagiporibacteria (free-living). These lineages differed in flagellar motility and chemotaxis genes unique to Pelagiporibacteria, and highly expanded families of restriction endonucleases, DNA methylases, transposases, CRISPR repeats, and toxin-antitoxin gene pairs in Entoporibacteria. Both lineages shared pathways for facultative anaerobic metabolism, denitrification, fermentation, organosulfur compound utilization, type IV pili, cellulosomes, and bacterial proteosomes. Unexpectedly, many features characteristic of eukaryotic host association were also shared, including genes encoding the synthesis of eukaryotic-like cell adhesion molecules, extracellular matrix digestive enzymes, phosphoinositol linked membrane glycolipids, and exopolysaccharide capsules. Complete Poribacteria 16S rRNA gene sequences were found to contain multiple mismatches to "universal" 16S rRNA gene primer sets, substantiating concerns about potential amplification failures in previous studies. A newly designed primer set corrects these mismatches, enabling more accurate assessment of Poribacteria abundance in diverse marine habitats where it may have previously been overlooked. PMID- 30291329 TI - Sulfurimonas subgroup GD17 cells accumulate polyphosphate under fluctuating redox conditions in the Baltic Sea: possible implications for their ecology. AB - The central Baltic Sea is characterized by a pelagic redox zone exhibiting high dark CO2 fixation rates below the chemocline. These rates are mainly driven by chemolithoautotrophic and denitrifying Sulfurimonas GD17 subgroup cells which are motile and fast-reacting r-strategists. Baltic Sea redox zones are unstable and a measurable overlap of nitrate and reduced sulfur, essential for chemosynthesis, is often only available on small scales and short times due to local mixing events. This raises the question of how GD17 cells gain access to electron donors or acceptors over longer term periods and under substrate deficiency. One possible answer is that GD17 cells store high-energy-containing polyphosphate during favorable nutrient conditions to survive periods of nutrient starvation. We used scanning electron microscopy with energy-dispersive X-ray spectroscopy to investigate potential substrate enrichments in single GD17 cells collected from Baltic Sea redox zones. More specific substrate enrichment features were identified in experiments using Sulfurimonas gotlandica GD1T, a GD17 representative. Sulfurimonas cells accumulated polyphosphate both in situ and in vitro. Combined genome and culture-dependent analyses suggest that polyphosphate serves as an energy reservoir to maintain cellular integrity at unfavorable substrate conditions. This redox-independent energy supply would be a precondition for sustaining the r-strategy lifestyle of GD17 and may represent a newly identified survival strategy for chemolithoautotrophic prokaryotes occupying eutrophic redox zones. PMID- 30291331 TI - Reviewer Recognition. PMID- 30291330 TI - Antiepileptic drug carbamazepine promotes horizontal transfer of plasmid-borne multi-antibiotic resistance genes within and across bacterial genera. AB - Antibiotic resistance is a severe global threat for public health, causing around 700,000 deaths per year. Horizontal gene transfer (HGT) is one of the most significant pathways to disseminate antibiotic resistance. It is commonly acknowledged that sub-minimum inhibition concentrations of antibiotics are major contributors in promoting antibiotic resistance through HGT. Pharmaceuticals are occurring in our environments at increased levels, yet little is known whether non-antibiotic pharmaceuticals cause or accelerate the dissemination of antibiotic resistance. Here, we report for the first time that the antiepileptic drug, carbamazepine, promotes conjugative transfer of antibiotic resistance genes. It was seen that environmentally relevant concentrations of carbamazepine (e.g., 0.05 mg/L) significantly enhanced the conjugative transfer of multiresistance genes carried by plasmid within and across bacterial genera. The underlying mechanisms of the enhanced HGT were revealed by detecting oxidative stress and cell membrane permeability, in combination with MinION DNA sequencing, genome-wide RNA sequencing, and proteomic analysis. Carbamazepine induced a series of acute responses, including increased levels of reactive oxygen species, the SOS response; increased cell membrane permeability, and pilus generation. Expressional levels of genes related to these processes were significantly upregulated during carbamazepine exposure. Given that HGT occurs widely among different species in various environments, these findings are an early warning for a wide assessment of the roles of non-antibiotic pharmaceuticals in the spread of antibiotic resistance. PMID- 30291332 TI - Phylogenetics of Mycoplasma hominis clinical strains associated with gynecological infections or infertility as disclosed by an expanded multilocus sequence typing scheme. AB - To our knowledge, the phylodistribution of M. hominis clinical strains associated with various pathological conditions of the urogenital tract has not been explored hitherto. Here we analyzed the genetic diversity and phylogenetic relationships among 59 M. hominis Tunisian clinical isolates, categorized as gynecological infections- or infertility-associated pathotypes. For this purpose, we developed an expanded multilocus sequence typing (eMLST) scheme, combining the previously reported multilocus sequence typing (MLST) loci (gyrB, tuf, ftsY, uvrA, gap) with a new selected set of putative virulence genes (p120', vaa, lmp1, lmp3, p60), referred herein to as multi-virulence-locus sequence typing (MVLST) loci. In doing so, M. hominis population was segregated into two distinct genetic lineages, which were differentially associated with each pathotype. Such a clear dichotomy was supported by several phylogenetic and population genetic analysis tools. Recombination was found to take place, but not sufficient enough to break down the overall clonal population structure of M. hominis, most likely as a result of purifying selection, which accommodated the most fit clones. In sum, and owing to the eMLST scheme described herein, we provide insightful data on the phylogenetics of M. hominis, arguing for the existence of genetically differentiable urogenital pathotypes.

PMID- 30291337 TI - Bone marrow hematopoietic dysfunction in untreated chronic lymphocytic leukemia patients. AB - The consequences of immune dysfunction in B-chronic lymphocytic leukemia (CLL) likely relate to the incidence of serious recurrent infections and second malignancies that plague CLL patients. The well-described immune abnormalities are not able to consistently explain these complications. Here, we report bone marrow (BM) hematopoietic dysfunction in early and late stage untreated CLL patients. Numbers of CD34+ BM hematopoietic progenitors responsive in standard colony-forming unit (CFU) assays, including CFU-GM/GEMM and CFU-E, were significantly reduced. Flow cytometry revealed corresponding reductions in frequencies of all hematopoietic stem and progenitor cell (HSPC) subsets assessed in CLL patient marrow. Consistent with the reduction in HSPCs, BM resident monocytes and natural killer cells were reduced, a deficiency recapitulated in blood. Finally, we report increases in protein levels of the transcriptional regulators HIF-1alpha, GATA-1, PU.1, and GATA-2 in CLL patient BM, providing molecular insight into the basis of HSPC dysfunction. Importantly, PU.1 and GATA 2 were rapidly increased when healthy HSPCs were exposed in vitro to TNFalpha, a cytokine constitutively produced by CLL B cells. Together, these findings reveal BM hematopoietic dysfunction in untreated CLL patients that provides new insight into the etiology of the complex immunodeficiency state in CLL. PMID- 30291336 TI - Histone deacetylase inhibitor targets CD123/CD47-positive cells and reverse chemoresistance phenotype in acute myeloid leukemia. AB - Chemoresistance may be due to the survival of leukemia stem cells (LSCs) that are quiescent and not responsive to chemotherapy or lie on the intrinsic or acquired resistance of the specific pool of AML cells. Here, we found, among well established LSC markers, only CD123 and CD47 are correlated with AML cell chemosensitivities across cell lines and patient samples. Further study reveals that percentages of CD123+CD47+ cells significantly increased in chemoresistant lines compared to parental cell lines. However, stemness signature genes are not significantly increased in resistant cells. Instead, gene changes are enriched in cell cycle and cell survival pathways. This suggests CD123 may serve as a biomarker for chemoresistance, but not stemness of AML cells. We further investigated the role of epigenetic factors in regulating the survival of chemoresistant leukemia cells. Epigenetic drugs, especially histone deacetylase inhibitors (HDACis), effectively induced apoptosis of chemoresistant cells. Furthermore, HDACi Romidepsin largely reversed gene expression profile of resistant cells and efficiently targeted and removed chemoresistant leukemia blasts in xenograft AML mouse model. More interestingly, Romidepsin preferentially targets CD123+ cells, while chemotherapy drug Ara-C mainly targeted fast-growing, CD123- cells. Therefore, Romidepsin alone or in combination with Ara-C may be a potential treatment strategy for chemoresistant patients.

PMID- 30291340 TI - Heterozygous loss-of-function variants of MEIS2 cause a triad of palatal defects, congenital heart defects, and intellectual disability. AB - Deletions on chromosome 15q14 are a known chromosomal cause of cleft palate, typically co-occurring with intellectual disability, facial dysmorphism, and congenital heart defects. The identification of patients with loss-of-function variants in MEIS2, a gene within this deletion, suggests that these features are attributed to haploinsufficiency of MEIS2. To further delineate the phenotypic spectrum of the MEIS2-related syndrome, we collected 23 previously unreported patients with either a de novo sequence variant in MEIS2 (9 patients), or a 15q14 microdeletion affecting MEIS2 (14 patients). All but one de novo MEIS2 variant were identified by whole-exome sequencing. One variant was found by targeted sequencing of MEIS2 in a girl with a clinical suspicion of this syndrome. In addition to the triad of palatal defects, heart defects, and developmental delay, heterozygous loss of MEIS2 results in recurrent facial features, including thin and arched eyebrows, short alae nasi, and thin vermillion. Genotype-phenotype comparison between patients with 15q14 deletions and patients with sequence variants or intragenic deletions within MEIS2, showed a higher prevalence of moderate-to-severe intellectual disability in the former group, advocating for an independent locus for psychomotor development neighboring MEIS2.

AB - The profession of genetic counseling (also called genetic counselling in many countries) began nearly 50 years ago in the United States, and has grown internationally in the past 30 years. While there have been many papers describing the profession of genetic counseling in individual countries or regions, data remains incomplete and has been published in diverse journals with limited access. As a result of the 2016 Transnational Alliance of Genetic Counseling (TAGC) conference in Barcelona, Spain, and the 2017 World Congress of Genetic Counselling in the UK, we endeavor to describe as fully as possible the global state of genetic counseling as a profession. We estimate that in 2018 there are nearly 7000 genetic counselors with the profession established or developing in no less than 28 countries. PMID- 30291343 TI - 1 in 38 individuals at risk of a dominant medically actionable disease. AB - Clinical genomic sequencing can identify pathogenic variants unrelated to the initial clinical question, but of medical relevance to the patients and their families. With ongoing discussions on the utility of disclosing or searching for such variants, it is of crucial importance to obtain unbiased insight in the prevalence of these incidental or secondary findings, in order to better weigh potential risks and benefits. Previous studies have reported a broad range of secondary findings ranging from 1 to 9%, merely attributable to differences in study design, cohorts tested, sequence technology used and genes analyzed. Here, we analyzed WES data of 1640 anonymized healthy Dutch individuals to establish the frequency of medically actionable disease alleles in an outbred population of European descent. Our study shows that 1 in 38 healthy individuals (2.7%) has a (likely) pathogenic variant in one of 59 medically actionable dominant disease genes for which the American College of Medical Genetics and Genomics (ACMG) recommends disclosure. Additionally, we identified 36 individuals (2.2%) to be a carrier of a recessive pathogenic disease allele. Whereas these frequencies of secondary findings are in line with what has been reported in the East-Asian population, the pathogenic variants are differently distributed across the 59 ACMG genes. Our results contribute to the debate on genetic risk factor screening in healthy individuals and the discussion whether the potential benefits of this knowledge and related preventive options, outweigh the risk of the emotional impact of the test result and possible stigmatization. PMID- 30291344 TI - Identification of a subset of microsatellite-stable endometrial carcinoma with high PD-L1 and CD8+ lymphocytes. AB - Immune checkpoint blockade has emerged as an effective therapeutic strategy for patients with advanced cancer. Identification of biomarkers associated with treatment efficacy will help to select patients more likely to respond to this approach. High levels of microsatellite instability, tumor expression of PD-L1, high tumor mutation burden, and increased tumor-infiltrating lymphocytes have all been associated with response to checkpoint inhibitor blockade. The purpose of this study was to determine if a subset of microsatellite-stable endometrioid endometrial carcinomas have higher immune cell infiltrates and/or expression of PD-L1. PD-L1 expression and characterization of immune cell infiltrates were analyzed in 132 microsatellite stable, FIGO grade 2 endometrioid carcinomas. PD L1 was positive in 48% (63/132) of the tumors. Tumor cell expression of PD-L1 was significantly associated with lymphatic/vascular invasion and deep myometrial invasion. PD-L1 expression was especially prominent at the invasive front and in foci of tumor-associated squamous metaplasia. Twenty-one cases (16% of the total) with more diffuse and/or especially strong PD-L1 expression were identified. This PD-L1 high subset was associated with significantly higher numbers of tumor associated CD3+ and CD8+ lymphocytes. Only one tumor in the PD-L1 high subset harbored a POLE mutation. PTEN immunohistochemical loss, a common event in endometrioid-type endometrial carcinoma and associated with local immune suppression in melanoma, was not associated with PD-L1 expression or lymphocyte/macrophage infiltration of the tumor. These results suggest that a subset of microsatellite-stable endometrial cancers has higher expression of PD L1 and increased tumor-associated CD3+ and CD8+ lymphocytes, characteristics more commonly associated with endometrial cancers with high levels of microsatellite instability. These results suggest that screening strategies to select only microsatellite instability-high advanced endometrial cancers for checkpoint inhibitor therapy might exclude patients who could potentially benefit from this therapeutic approach. PMID- 30291345 TI - Time series analysis of TP53 gene mutations in recurrent HPV-negative vulvar squamous cell carcinoma. AB - The impact of TP53 gene mutations in recurrent HPV-negative vulvar squamous cell carcinomas is unclear. TP53 gene mutations were analyzed in archival tissues of 24 primary squamous cell carcinoma and local vulvar recurrences arising in chronic inflammatory dermatoses by analyzing the full coding sequence of the TP53 gene and correlated with disease-free survival. After resection of the primary squamous cell carcinoma with clear margins 19/24 patients had one and 5/24 had multiple recurrences. The first recurrence occurred after median of 46 months (range 12-180 months). In all, 17/24 (71%) primary squamous cell carcinomas had TP53 gene mutations and recurred after median disease-free intervals of 33 months (range 12-180). 14/17 (88%) recurrent squamous cell carcinomas carried again TP53 gene mutations, five with identical and nine with different, more complex TP53 gene mutations. 7/24 (29%) patients with a p53 wild-type primary SCC had the first recurrence after median 65 months (range 14-144) featuring p53 wild-type in 3/7 (43%) and TP53 gene mutations in 4/7 (57%) recurrent squamous cell carcinomas. Disease-free intervals of > 5 years (60-180 months) were observed in 10/24 patients total (42%; equally divided among p53 wild-type (5/7; 71%) and TP53 gene mutated (5/17; 29%) squamous cell carcinomas). In summary, squamous cell carcinomas recurred in the residual vulvar dermatosis independent of TP53 gene mutational status of the primary squamous cell carcinoma. The majority of TP53 gene mutated cancers recurred with different TP53 gene mutations, some of them more complex, and patients with p53 wild type developed TP53 gene mutations in the recurrent squamous cell carcinomas, possibly indicating increased genetic instability in longstanding chronic inflammatory dermatoses. A change of TP53 gene mutational status after > 5 years suggests de novo oncogenic events/carcinogenesis. Longer disease-free intervals in patients with p53 wild type primary squamous cell carcinoma suggest that TP53 gene mutational status may serve as a prognostic marker for disease-free intervals. PMID- 30291347 TI - A novel analytical model of MGMT methylation pyrosequencing offers improved predictive performance in patients with gliomas. AB - The methylation status of the promoter of MGMT gene is a crucial factor influencing clinical decision-making in patients with gliomas. MGMT pyrosequencing results are often dichotomized by a cut-off value based on an average of several tested CpGs. However, this method frequently results in a "gray zone", representing a dilemma for physicians. We therefore propose a novel analytical model for MGMT methylation pyrosequencing. MGMT CpG heterogeneity was investigated in 213 glioma patients in two tested cohorts: cohort A in which CpGs 75-82 were tested and cohort B in which CpGs 72-78 were tested. The predictive performances of the novel and traditional averaging models were compared in 135 patients who received temozolomide using receiver operating characteristic curves and Kaplan-Meier curves, and in patients stratified according to isocitrate dehydrogenase gene mutation status. The results were validated in an independent cohort of 65 consecutive patients with high-grade gliomas from the Chinese Glioma Genome Atlas database. Heterogeneity of MGMT promoter CpG methylation level was observed in most gliomas. The optimal cut-off value for each individual CpG varied from 4-16%. The current analysis defined MGMT promoter methylation as occurring when at least three CpGs exceeded their respective cut-off values. This novel analysis could accurately predict the prognosis of patients in the methylation "gray zone" according to the standard averaging method, and improved the area under the curves from 0.67, 0.76, and 0.67 to 0.70, 0.84, and 0.72 in cohorts A, B, and the validation cohort, respectively, demonstrating superiority of this analytical method in all three cohorts. Furthermore, the advantages of the novel analysis were retained regardless of WHO grade and isocitrate dehydrogenase gene mutation status. In conclusion, this novel analytical model offers an improved clinical predictive performance for MGMT pyrosequencing results and is suitable for clinical use in patients with gliomas. PMID- 30291348 TI - Let there be nano. PMID- 30291346 TI - H3K27me3 deficiency defines a subset of dedifferentiated chondrosarcomas with characteristic clinicopathological features. AB - Dedifferentiated chondrosarcoma is a rare bone sarcoma, whose genetic background remains incompletely understood. Mutations in SUZ12 or EED, which encode polycomb repressive complex 2 (PRC2) components, and resulting deficiency in H3K27me3 are characteristic features of the majority of malignant peripheral nerve sheath tumors. Here, we investigated H3K27me3 and PRC2 status in dedifferentiated chondrosarcoma. Among 19 evaluable dedifferentiated chondrosarcoma cases, six (32%) showed immunohistochemical loss of H3K27me3 only in the dedifferentiated component, whereas the well-differentiated component retained H3K27me3. H3K27me3 deficient dedifferentiated chondrosarcoma occurred in two men and four women with a median age of 66. All of these tumors affected bones of the upper half of the body, with the ribs being preferentially involved, which represented a significantly different distribution compared to that in the 13 H3K27me3-intact dedifferentiated chondrosarcomas. H3K27me3-deficient dedifferentiated chondrosarcomas were histologically different from H3K27me3-intact dedifferentiated chondrosarcomas, as the former invariably demonstrated dedifferentiated histology with a striking similarity to classic malignant peripheral nerve sheath tumor, comprising sweeping to swirling fascicles of relatively uniform spindle cells. Heterologous rhabdomyoblastic differentiation, the focal presence of grade 3 chondrosarcoma histology, and a cartilaginous component in the metastatic sites were exclusively seen in some cases of H3K27me3 deficient dedifferentiated chondrosarcoma. In all three H3K27me3-deficient dedifferentiated chondrosarcomas that contained focal grade 3 histology, dedifferentiated components did not juxtapose to the grade 3 areas but transitioned abruptly from the grade 1-2 components. Targeted next generation sequencing, which was successfully performed on four H3K27me3-deficient dedifferentiated chondrosarcomas, identified an IDH2 mutation in one case and COL2A1 truncations in three cases. The dedifferentiated areas of three cases harbored SUZ12 or EED alterations, which were absent in the well-differentiated component, suggesting a role for PRC2 aberrations in dedifferentiation. H3K27me3 deficiency defines a novel subset of dedifferentiated chondrosarcoma that requires recognition because of its diagnostic and potential clinical implications. PMID- 30291349 TI - Interfacing nature's catalytic machinery with synthetic materials for semi artificial photosynthesis. AB - Semi-artificial photosynthetic systems aim to overcome the limitations of natural and artificial photosynthesis while providing an opportunity to investigate their respective functionality. The progress and studies of these hybrid systems is the focus of this forward-looking perspective. In this Review, we discuss how enzymes have been interfaced with synthetic materials and employed for semi-artificial fuel production. In parallel, we examine how more complex living cellular systems can be recruited for in vivo fuel and chemical production in an approach where inorganic nanostructures are hybridized with photosynthetic and non photosynthetic microorganisms. Side-by-side comparisons reveal strengths and limitations of enzyme- and microorganism-based hybrid systems, and how lessons extracted from studying enzyme hybrids can be applied to investigations of microorganism-hybrid devices. We conclude by putting semi-artificial photosynthesis in the context of its own ambitions and discuss how it can help address the grand challenges facing artificial systems for the efficient generation of solar fuels and chemicals.

PMID- 30291360 TI - A molecular mechanism for calcium-mediated synaptotagmin-triggered exocytosis. AB - The regulated exocytotic release of neurotransmitter and hormones is accomplished by a complex protein machinery whose core consists of SNARE proteins and the calcium sensor synaptotagmin-1. We propose a mechanism in which the lipid membrane is intimately involved in coupling calcium sensing to release. We found that fusion of dense core vesicles, derived from rat PC12 cells, was strongly linked to the angle between the cytoplasmic domain of the SNARE complex and the plane of the target membrane. We propose that, as this tilt angle increases, force is exerted on the SNARE transmembrane domains to drive the merger of the two bilayers. The tilt angle markedly increased following calcium-mediated binding of synaptotagmin to membranes, strongly depended on the surface electrostatics of the membrane, and was strictly coupled to the lipid order of the target membrane. PMID- 30291361 TI - Transcription-associated histone pruning demarcates macroH2A chromatin domains. AB - The histone variant macroH2A occupies large repressive domains throughout the genome; however, mechanisms underlying its precise deposition remain poorly understood. Here, we characterize de novo chromatin deposition of macroH2A2 using temporal genomic profiling in murine-derived fibroblasts devoid of all macroH2A isoforms. We find that macroH2A2 is first pervasively deposited genome wide at both steady-state domains and adjacent transcribed regions, the latter of which are subsequently pruned, establishing mature macroH2A2 domains. Pruning of macroH2A2 can be counteracted by chemical inhibition of transcription. Further, locus-specific transcriptional manipulation reveals that gene activation depletes pre-existing macroH2A2, while silencing triggers ectopic macroH2A2 accumulation. We demonstrate that the FACT (facilitates chromatin transcription) complex is required for macroH2A2 pruning within transcribed chromatin. Taken together, we have identified active chromatin as a boundary for macroH2A domains through a transcription-associated 'pruning' mechanism that establishes and maintains the faithful genomic localization of macroH2A variants. PMID- 30291362 TI - Structural basis for sigma1 receptor ligand recognition. AB - The sigma1 receptor is a poorly understood membrane protein expressed throughout the human body. Ligands targeting the sigma1 receptor are in clinical trials for treatment of Alzheimer's disease, ischemic stroke, and neuropathic pain. However, relatively little is known regarding the sigma1 receptor's molecular function. Here, we present crystal structures of human sigma1 receptor bound to the antagonists haloperidol and NE-100, and the agonist (+)-pentazocine, at crystallographic resolutions of 3.1 A, 2.9 A, and 3.1 A, respectively. These structures reveal a unique binding pose for the agonist. The structures and accompanying molecular dynamics (MD) simulations identify agonist-induced structural rearrangements in the receptor. Additionally, we show that ligand binding to sigma1 is a multistep process that is rate limited by receptor conformational change. We used MD simulations to reconstruct a ligand binding pathway involving two major conformational changes. These data provide a framework for understanding the molecular basis for sigma1 agonism.

AB - PURPOSE: The aim of the study was to investigate any metabolic changes on magnetic resonance spectroscopy (MRS) throughout the visual pathway of the brain in patients with glaucoma and a control group and correlate the results with clinical findings. MATERIAL AND METHODS: A total of 87 patients were enrolled in the study, 30 healthy controls, 25 glaucoma, 16 suspected glaucoma (GS) and 16 ocular hypertension (OHT) patients. A single voxel MRS on TE 30 ms was performed by placing the volume of interest (VOI) on the corpus geniculatum laterale (CGL) and primary visual cortex (VC). Peak values of metabolites, such as N-acetyl aspartate (NAA), creatine (Cr), choline (Cho) and Myo-inositol (Ins) were investigated on MRS. The MRS results were correlated with age, intraocular pressure (IOP), retinal nerve fiber length (RNFL), mean deviation (MD) and cup disk ratio (CD). RESULTS: The NAA values obtained from the CGL in glaucoma and GS cases were lower than the healthy control group. The Cho values at CGL in glaucoma were lower than GS and controls. There was a negative correlation between NAA values of the VC and CD in glaucoma cases. Additionally, there was a negative correlation between age and RNFL in both glaucoma and GS cases. CONCLUSION: The use of MRS can reveal neurodegeneration in CGL and VC in patients with glaucoma. Depiction of metabolic changes throughout the visual pathways via MRS will guide the treatment planning and follow-up in glaucoma and GS cases.

AB - We generalize chaos game representation (CGR) to higher dimensional spaces while maintaining its bijection, keeping such method sufficiently representative and mathematically rigorous compare to previous attempts. We first state and prove the asymptotic property of CGR and our generalized chaos game representation (GCGR) method. The prediction follows that the dissimilarity of sequences which possess identical subsequences but distinct positions would be lowered exponentially by the length of the identical subsequence; this effect was taking place unbeknownst to researchers. By shining a spotlight on it now, we show the effect fundamentally supports (G)CGR as a similarity measure or feature extraction technique. We develop two feature extraction techniques: GCGR-Centroid and GCGR-Variance. We use the GCGR-Centroid to analyze the similarity between protein sequences by using the datasets 9 ND5, 24 TF and 50 beta-globin proteins. We obtain consistent results compared with previous studies which proves the significance thereof. Finally, by utilizing support vector machines, we train the anticancer peptide prediction model by using both GCGR-Centroid and GCGR Variance, and achieve a significantly higher prediction performance by employing the 3 well-studied anticancer peptide datasets. PMID- 30291363 TI - XLF and APLF bind Ku80 at two remote sites to ensure DNA repair by non-homologous end joining. AB - The Ku70-Ku80 (Ku) heterodimer binds rapidly and tightly to the ends of DNA double-strand breaks and recruits factors of the non-homologous end-joining (NHEJ) repair pathway through molecular interactions that remain unclear. We have determined crystal structures of the Ku-binding motifs (KBM) of the NHEJ proteins APLF (A-KBM) and XLF (X-KBM) bound to a Ku-DNA complex. The two KBM motifs bind remote sites of the Ku80 alpha/beta domain. The X-KBM occupies an internal pocket formed by an unprecedented large outward rotation of the Ku80 alpha/beta domain. We observe independent recruitment of the APLF-interacting protein XRCC4 and of XLF to laser-irradiated sites via binding of A- and X-KBMs, respectively, to Ku80. Finally, we show that mutation of the X-KBM and A-KBM binding sites in Ku80 compromises both the efficiency and accuracy of end joining and cellular radiosensitivity. A- and X-KBMs may represent two initial anchor points to build the intricate interaction network required for NHEJ.

AB - Tenacibaculosis is a major bacterial disease that causes severe fish outbreaks and losses and limits the culture of a variety of commercially valuable anadromous and marine fish species in Europe, America, Asia and Oceania. Fish affected by tenacibaculosis have external lesions and necrosis that affect different areas of the body surface, reducing their commercial value. Several species of Tenacibaculum have been identified as the causal agent of tenacibaculosis in fish, including Tenacibaculum maritimum, Tenacibaculum soleae, Tenacibaculum discolor, Tenacibaculum gallaicum, Tenacibaculum dicentrarchi and "Tenacibaculum finnmarkense" (quotations marks denote species that have not been validly published). Diagnosis of tenacibaculosis is usually based on culture dependent detection and identification techniques which are time-consuming and do not allow to differentiate closely related species. The development of reliable techniques for studying the relationships between members of the genus Tenacibaculum and for distinguishing fish-pathogenic species of Tenacibaculum genus is, therefore, a key step in understanding the diversity and incidence of tenacibaculosis in global aquaculture, designing effective prevention strategies and early implementation of infection control measures. In this review, recent advances in molecular, serological, proteomic and chemotaxonomic techniques developed for the identification and differentiation of Tenacibaculum species, as well as for the analysis of their genetic and epidemiological relationships are discussed. Key features of current diagnostic methods likely to facilitate control and prevention of tenacibaculosis and to avoid the spread of its aetiological agents are also outlined. PMID- 30291368 TI - Long-term preservation of potato leafroll virus, potato virus S, and potato spindle tuber viroid in cryopreserved shoot tips. AB - Availability of and easy access to diverse plant viruses and viroids is a prerequisite in applied and basic studies related to viruses and viroids. Long term preservation of viruses and viroids is difficult. A protocol was described for long-term preservation of potato leafroll virus (PLRV), potato virus S (PVS), and potato spindle tuber viroid (PSTVd) in cryopreserved shoot tips of potato cv. Zihuabai. Shoot regrowth levels following cryopreservation were higher in 1.5 mm shoot tips (58-60%) than in 0.5-mm-ones (30-38%). All shoots recovered from 0.5 mm-shoot tips were PVS- and PSTVd-preserved, but none of them were PLRV preserved. Cryopreservation of 1.5-mm-shoot tips resulted in 35% and 100% of PLRV and PVS- and PSTVd-preserved shoots. Studies on cell survival patterns and virus localization provided explanations to the varying PLRV-preservation frequencies produced by cryopreservation of the two sizes of shoot tips. Although micropropagation efficiencies were low after 12 weeks of subculture following cryopreservation, similar efficiencies were obtained after 16 weeks of subculture in pathogen-preserved shoots recovered from cryopreservation, compared with the diseased in vitro stock shoots (the control). Pathogen concentrations in the three pathogens-preserved shoots analyzed by qRT-PCR were similar to those in micropropagated shoots. The three pathogens cryopreserved in shoot tips were readily transmitted by grafting and mechanical inoculation to potato plants. PLRV, PVS, and PSTVd represent a diverse range of plant viruses and viroid in terms of taxonomy and infectious ability. Therefore, shoot tip cryopreservation opens a new avenue for long-term preservation of the virus and viroid. PMID- 30291369 TI - Effects of chronic kidney disease stage 4, end-stage renal disease, or dialysis on the plasma concentrations of ombitasvir, paritaprevir, ritonavir, and dasabuvir in patients with chronic HCV infection: pharmacokinetic analysis of the phase 3 RUBY-I and RUBY-II trials. AB - PURPOSE: To characterize the pharmacokinetics of ombitasvir, paritaprevir, ritonavir, dasabuvir, and ribavirin in hepatitis C virus (HCV)-infected patients with chronic kidney disease stage 4 (CKD4) or end-stage renal disease (ESRD), including those on dialysis, in the open-label phase 3 RUBY-I and RUBY-II studies. METHODS: Patients (n = 18 CKD4, n = 68 ESRD) received ombitasvir/paritaprevir/ritonavir 25/150/100 mg once daily +/- dasabuvir 250 mg twice daily +/- ribavirin 200 mg once daily for 12 or 24 weeks. Intensive pharmacokinetic samples were collected from ten patients; sparse samples were collected from all patients. Arterial and venous samples were collected from three patients during hemodialysis. Area under the plasma concentration-time curve (AUC) was estimated using noncompartmental analyses for intensive data, and steady-state trough concentrations (Ctrough) were obtained from the sparse data. Pharmacokinetic results from RUBY-I and RUBY-II were compared empirically to historical data. RESULTS: The AUC values of ombitasvir, paritaprevir, ritonavir, and dasabuvir were comparable between CKD4 and ESRD patients and were within the range of values observed in historical studies; dialysis had no effect on drug exposures. Ribavirin was extracted during hemodialysis but had similar exposures on dialysis and non-dialysis days. Individual steady-state Ctrough values for each drug overlapped between CKD4 and ESRD patients, and values in both groups were similar to historical values. CONCLUSION: Plasma concentrations of ombitasvir, paritaprevir, ritonavir, and dasabuvir were not altered by renal impairment or dialysis, suggesting these agents can be administered to HCV infected CKD4 or ESRD patients, including those on dialysis, without dose adjustment.

AB - BACKGROUND AND PURPOSE: The purpose of this randomized, placebo-controlled, double-blind study was to investigate the preventive effect of topical administration of atorvastatin (ATV) on the acute radiation-induced skin toxicity in patients with breast cancer. PATIENTS AND METHODS: Seventy breast cancer patients were randomly assigned to use topical ATV 1% or placebo gels during radiotherapy twice daily. Radiation-induced dermatitis was classified according to the radiation therapy oncology group (RTOG) criteria, as well as pain and itching were scored according to VAS (visual analogue scale) for 6 weeks of treatment. RESULTS: Topical administration of ATV gel during radiotherapy reduced significantly radiation-induced breast swelling, itching, and pain in breast cancer patients by factors of 1.8, 1.7, and 1.5, respectively. ATV reduced the redness caused by radiotherapy in patients as compared with placebo; however, this difference was statistically not significant. CONCLUSION: ATV was able to reduce significantly itching, breast edema, and pain in patients during radiotherapy.

AB - In most cases of juvenile idiopathic arthritis (JIA), disease remission can be achieved by a multidisciplinary approach using modern medication. However, JIA is currently incurable An interdisciplinary concept is therefore needed for long term development of affected joints and tendons. Only early interdisciplinary treatment strategies can improve long-term outcomes in patients with a complicated disease course or persistent disease activity, thereby delaying or even avoiding joint replacement. An early interdisciplinary assessment and treatment planning according to surgical orthopedic rheumatology aspects is now state of the art and will continue to be in the future, especially in treatment refractory disease courses. PMID- 30291372 TI - [Therapeutic options in juvenile idiopathic arthritis : Part 1: Nonsurgical treatment]. AB - The treatment of children and adolescents with juvenile idiopathic arthritis (JIA) has progressed substantially during recent years. Multiple different factors have played a role in this advancement: improved medical treatment due to the introduction of new drugs, structural improvements with provision of units specializing in childhood rheumatology, multidisciplinary treatment concepts, structured educational programs for patients and parents, improved functional treatment including sports therapy, and selective surgical and orthopedic interventions improving functional capacities. Current treatment strategies in JIA are aimed at achieving disease remission, i.e., control of disease activity and re-establishment of age-appropriate functional capacities. This review summarizes important developments in the conservative treatment of JIA. Part 2 deals with orthopedic and surgical treatment strategies.

A review of the recent literature on the use of FDG PET for assessment of immunotherapy is presented, and recommendations are provided for assessing tumour response and reporting immune-related side effects with FDG PET based on published data and experts' experience. Representative clinical cases are also discussed. PMID- 30291374 TI - Metabotropic glutamate receptor subtype 5 is altered in LPS-induced murine neuroinflammation model and in the brains of AD and ALS patients. AB - PURPOSE: The aim of the present study was to determine the expression levels of mGluR5 in different mouse strains after induction of neuroinflammation by lipopolysaccharide (LPS) challenge and in the brains of patients with Alzheimer's disease (AD) and amyotrophic lateral sclerosis (ALS) post mortem to investigate mGluR5 expression in human neurodegenerative diseases. METHODS: C57BL/6 and CD1 mice were injected intraperitoneally with either 10 mg/kg LPS or saline. mGluR5 and TSPO mRNA levels were measured after 1 and 5 days by qPCR, and mGluR5 protein levels were determined by PET imaging with the mGluR5-specific radiotracer [18F]PSS232. mGluR5 expression was evaluated in the post-mortem brain slices from AD and ALS patients using in vitro autoradiography. RESULTS: mGluR5 and TSPO mRNA levels were increased in brains of C57BL/6 and CD1 mice 1 day after LPS treatment and remained significantly increased after 5 days in C57BL/6 mice but not in CD1 mice. Brain PET imaging with [18F]PSS232 confirmed increased mGluR5 levels in the brains of both mouse strains 1 day after LPS treatment. After 5 days, mGluR5 levels in CD1 mice declined to the levels in vehicle-treated mice but remained high in C57BL/6 mice. Autoradiograms revealed a severalfold higher binding of [18F]PSS232 in post-mortem brain slices from AD and ALS patients compared with the binding in control brains. CONCLUSION: LPS-induced neuroinflammation increased mGluR5 levels in mouse brain and is dependent on the mouse strain and time after LPS treatment. mGluR5 levels were also increased in human AD and ALS brains in vitro. PET imaging of mGluR5 levels could potentially be used to diagnose and monitor therapy outcomes in patients with AD and ALS. PMID- 30291375 TI - Tetraspanin 1 inhibits TNFalpha-induced apoptosis via NF-kappaB signaling pathway in alveolar epithelial cells. AB - OBJECTIVE: Tetraspanin family plays an important role in the pathogenesis of cancer, but its role in lung fibrosis is unknown. To determine whether tetraspanin 1 (TSPAN1), a member of the family, may be involved in the pathogenesis of pulmonary fibrosis. METHODS: TNFalpha -stimulated human alveolar epithelial (A549) and alveolar epithelial type II cell (AT2) were treated in vitro. Murine pulmonary fibrosis model was generated by injection of bleomycin (BLM). The expression of TSPAN1 was examined in vivo using the bleomycin-induced lung fibrosis model and tissue sample of IPF patients. Then we transfected the cells with TSPAN1 siRNA or plasmid and detected the expression changes of related proteins and cell apoptosis. RESULTS: In our study, we found that TSPAN1 was markedly down-regulated in lung tissue of patients with idiopathic pulmonary fibrosis (IPF) and in bleomycin-induced pulmonary fibrosis in mice. We also found that TSPAN1 was significantly down-regulated in A549 and primary (AT2) cells following exposure to TNFalpha. Meanwhile, TSPAN1 inhibited p-IkappaBalpha, which attenuated nuclear NF-kappaB translocation and activation and inhibited apoptosis. We demonstrated that TSPAN1 reduced Bax translocation and caspase-3 activation, inhibited the apoptosis by regulating the NF-kappaB pathway in response to TNFalpha. CONCLUSIONS: We conclude that TSPAN1 mediated apoptosis resistance of alveolar epithelial cells by regulating the NF-kappaB pathway. TSPAN1 may be a potential therapeutic target for pulmonary fibrosis or acute lung injury. PMID- 30291376 TI - Latent class analysis of ARDS subphenotypes: a secondary analysis of the statins for acutely injured lungs from sepsis (SAILS) study. AB - PURPOSE: Using latent class analysis (LCA), we have consistently identified two distinct subphenotypes in four randomized controlled trial cohorts of ARDS. One subphenotype has hyper-inflammatory characteristics and is associated with worse clinical outcomes. Further, within three negative clinical trials, we observed differential treatment response by subphenotype to randomly assigned interventions. The main purpose of this study was to identify ARDS subphenotypes in a contemporary NHLBI Network trial of infection-associated ARDS (SAILS) using LCA and to test for differential treatment response to rosuvastatin therapy in the subphenotypes. METHODS: LCA models were constructed using a combination of biomarker and clinical data at baseline in the SAILS study (n = 745). LCA modeling was then repeated using an expanded set of clinical class-defining variables. Subphenotypes were tested for differential treatment response to rosuvastatin. RESULTS: The two-class LCA model best fit the population. Forty percent of the patients were classified as the "hyper-inflammatory" subphenotype. Including additional clinical variables in the LCA models did not identify new classes. Mortality at day 60 and day 90 was higher in the hyper-inflammatory subphenotype. No differences in outcome were observed between hyper-inflammatory patients randomized to rosuvastatin therapy versus placebo. CONCLUSIONS: LCA using a two-subphenotype model best described the SAILS population. The subphenotypes have features consistent with those previously reported in four other cohorts. Addition of new class-defining variables in the LCA model did not yield additional subphenotypes. No treatment effect was observed with rosuvastatin. These findings further validate the presence of two subphenotypes and demonstrate their utility for patient stratification in ARDS. PMID- 30291377 TI - Performance of Doppler-based resistive index and semi-quantitative renal perfusion in predicting persistent AKI: results of a prospective multicenter study. AB - PURPOSE: The Doppler-based resistive index (RI) and semi-quantitative evaluation of renal perfusion using color Doppler (SQP) have shown promising results for predicting persistent acute kidney injury (AKI) in preliminary studies. This study aimed at evaluating the performance of RI and SQP to predict short-term renal prognosis in critically ill patients. METHODS: Prospective multicenter cohort study including unselected critically ill patients. Renal Doppler was performed at admission to the intensive care unit. The diagnostic performance of RI and SQP to predict persistent AKI at day 3 was evaluated. RESULTS: Overall, 371 patients were included, of whom 351 could be assessed for short-term renal recovery. Two thirds of the included patients had AKI (n = 233; 66.3%), of whom 136 had persistent AKI (58.4%). Doppler-based RI was higher and SQP lower in AKI patients and according to AKI recovery. Overall performance in predicting persistent AKI was however poor with area under ROC curve of respectively 0.58 (95% CI 0.52-0.64) and 0.59 (95% CI 0.54-0.65) for RI and SQP. Optimal cutoff was respectively 0.71 and 2 for RI and SQP. At optimal cutoff, sensitivity and specificity were 50% (95% CI 41-58%) and 68% (62-74%) for RI and 39% (32-45%) and 75% (66-82%) for SQP. CONCLUSION: Although statistically associated with AKI occurrence, RI and SQP perform poorly in predicting persistent AKI at day 3. Further studies are needed to adequately describe factors influencing Doppler based assessment of renal perfusion and to delineate whether these indicators may be useful at the bedside. CLINICALTRIAL.GOV: NCT02355314. PMID- 30291378 TI - Mechanical power of ventilation is associated with mortality in critically ill patients: an analysis of patients in two observational cohorts. AB - PURPOSE: Mechanical power (MP) may unify variables known to be related to development of ventilator-induced lung injury. The aim of this study is to examine the association between MP and mortality in critically ill patients receiving invasive ventilation for at least 48 h. METHODS: This is an analysis of data stored in the databases of the MIMIC-III and eICU. Critically ill patients receiving invasive ventilation for at least 48 h were included. The exposure of interest was MP. The primary outcome was in-hospital mortality. RESULTS: Data from 8207 patients were analyzed. Median MP during the second 24 h was 21.4 (16.2 28.1) J/min in MIMIC-III and 16.0 (11.7-22.1) J/min in eICU. MP was independently associated with in-hospital mortality [odds ratio per 5 J/min increase (OR) 1.06 (95% confidence interval (CI) 1.01-1.11); p = 0.021 in MIMIC-III, and 1.10 (1.02 1.18); p = 0.010 in eICU]. MP was also associated with ICU mortality, 30-day mortality, and with ventilator-free days, ICU and hospital length of stay. Even at low tidal volume, high MP was associated with in-hospital mortality [OR 1.70 (1.32-2.18); p < 0.001] and other secondary outcomes. Finally, there is a consistent increase in the risk of death with MP higher than 17.0 J/min. CONCLUSION: High MP of ventilation is independently associated with higher in hospital mortality and several other outcomes in ICU patients receiving invasive ventilation for at least 48 h. PMID- 30291380 TI - Impact of mode of delivery of twins on the pelvic floor 3 and 12 months post partum-part II. AB - INTRODUCTION AND HYPOTHESIS: To compare the impact of vaginal delivery (VD) versus cesarean section (CS) on the pelvic floor in twin primiparae at 3 and 12 months postpartum. METHODS: This comparative multicenter prospective cohort from a large French national cohort study consisted of primiparas who gave birth to live twins after 34 weeks of gestation. The primary end point was the postnatal urinary incontinence rate 3 months postpartum. The secondary end points were the pelvic floor dysfunction (PFD) at 3 and 12 months based on PFDI-20, PFIQ-7, PISQ 12, and SF-12 responses. RESULTS: A total of 2812 patients in 172 French maternity units were recruited between February 2014 and March 2015: 1076 (38%) responded at 3 and 12 months (61% at 3 months); 1155 were analyzed at 3 months (556 VD and 599 CS) and 800 at 12 months (394 VD and 406 CS). VD was associated with more symptoms at 3 months [median PFDI-20 score 25/300 (8-50) vs. 17/300 (4 36) after CS; p < 0.0001]. Vaginal bulge was more frequently reported after VD (9 vs. 4%; p = 0.0015). Abdnormal PFD-related quality-of-life scores (scores > 0) were more frequent after VD at 3 months (58 vs. 42%; p < 0.0001) and 12 months (57 vs. 43%; p = 0.0020), indicating greater discomfort. However, SF-12 scores were higher after VD [56 (53-59) vs. 55 (51-58)] at 12 months, indicating better general quality of life. CONCLUSIONS: Mode of delivery is significantly associated with pelvic organ prolapse symptoms 3 months postpartum, which regress by 12 months, probably because of the known spontaneous postnatal improvement of PFDs. PMID- 30291381 TI - Diagnostic yield of head CT in pediatric emergency department patients with acute psychosis or hallucinations. AB - BACKGROUND: Children presenting to the emergency department with acute psychosis or hallucinations sometimes undergo a head CT to evaluate for a causative lesion. The diagnostic yield of head CT in this scenario has not been reported. OBJECTIVE: To determine the yield for head CT in children with acute psychosis or hallucinations. MATERIALS AND METHODS: We retrospectively searched the radiology report database over a 7.5-year period for head CT reports for pediatric emergency department patients using the following keywords: hallucination, psychosis, psychotic or "hearing voices." All reports were categorized as normal or abnormal, and we reviewed and categorized the abnormal cases. We calculated the 95% confidence interval for abnormal CTs using the method of Clopper and Pearson. RESULTS: We identified 397 pediatric emergency department head CTs. We excluded one non-diagnostic exam. We excluded 34 additional cases (which were all normal) because of clinical indications that might have independently triggered a head CT. Of the remaining 362 cases, 12 reports described abnormalities or variants and we reviewed them individually. Based on consensus review, four were normal, four had congenital malformations, three had encephalomalacia versus demyelination and one demonstrated cortical atrophy. There were no cases with actionable findings such as mass, hemorrhage, infection or hydrocephalus. The 95% confidence interval for a CT demonstrating causative findings was calculated at 0 0.82%. CONCLUSION: In the absence of concerning factors such as focal neurological deficits, evidence of central nervous system infection, trauma or headache, routine screening head CT might not be warranted in children presenting with acute psychosis or hallucinations. PMID- 30291379 TI - Early PREdiction of sepsis using leukocyte surface biomarkers: the ExPRES-sepsis cohort study. AB - PURPOSE: Reliable biomarkers for predicting subsequent sepsis among patients with suspected acute infection are lacking. In patients presenting to emergency departments (EDs) with suspected acute infection, we aimed to evaluate the reliability and discriminant ability of 47 leukocyte biomarkers as predictors of sepsis (Sequential Organ Failure Assessment score >= 2 at 24 h and/or 72 h following ED presentation). METHODS: In a multi-centre cohort study in four EDs and intensive care units (ICUs), we standardised flow-cytometric leukocyte biomarker measurement and compared patients with suspected acute infection (cohort-1) with two comparator cohorts: ICU patients with established sepsis (cohort-2), and ED patients without infection or systemic inflammation but requiring hospitalization (cohort-3). RESULTS: Between January 2014 and February 2016, we recruited 272, 59 and 75 patients to cohorts 1, 2, and 3, respectively. Of 47 leukocyte biomarkers, 14 were non-reliable, and 17 did not discriminate between the three cohorts. Discriminant analyses for predicting sepsis within cohort-1 were undertaken for eight neutrophil (cluster of differentiation antigens (CD) CD15; CD24; CD35; CD64; CD312; CD11b; CD274; CD279), seven monocyte (CD35; CD64; CD312; CD11b; HLA-DR; CD274; CD279) and a CD8 T-lymphocyte biomarker (CD279). Individually, only higher neutrophil CD279 [OR 1.78 (95% CI 1.23-2.57); P = 0.002], higher monocyte CD279 [1.32 (1.03-1.70); P = 0.03], and lower monocyte HLA-DR [0.73 (0.55-0.97); P = 0.03] expression were associated with subsequent sepsis. With logistic regression the optimum biomarker combination was increased neutrophil CD24 and neutrophil CD279, and reduced monocyte HLA-DR expression, but no combination had clinically relevant predictive validity. CONCLUSIONS: From a large panel of leukocyte biomarkers, immunosuppression biomarkers were associated with subsequent sepsis in ED patients with suspected acute infection. CLINICAL TRIAL REGISTRATION: NCT02188992. PMID- 30291382 TI - Technical success and outcomes in pediatric patients undergoing transjugular intrahepatic portosystemic shunt placement: a 20-year experience. AB - BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) placement has been extensively studied in adults. The experience with TIPS placement in pediatric patients, however, is limited. OBJECTIVE: The purpose of this study was to report technical success and clinical outcomes in pediatric patients undergoing TIPS placement. MATERIALS AND METHODS: Twenty-one children - 12 (57%) boys and 9 (43%) girls, mean age 12.1 years (range, 2-17 years) - underwent TIPS placement from January 1997 to January 2017. Etiologies of hepatic dysfunction included biliary atresia (n=5; 24%), cryptogenic cirrhosis (n=4; 19%), portal or hepatic vein thrombosis (n=4, 14%), autosomal-recessive polycystic kidney disease (n=3; 14%), primary sclerosing cholangitis (n=2; 10%) and others (n=3, 14%). Indications for TIPS placement included variceal hemorrhage (n=20; 95%) and refractory ascites (n=1; 5%). Technical success, manometry findings, stent type, hemodynamic success, complications, liver enzymes, and clinical outcomes were recorded. RESULTS: TIPS placement was technically successful in 20 of 21 (95%) children, with no immediate complications. Mean pre- and post-TIPS portosystemic gradient was 18.5+/-10.7 mmHg and 7.1+/-3.9 mmHg, respectively. Twenty-two total stents were successfully placed in 20 children. Stents used included: Viatorr (n=9; 41%), Wallstent (n=7; 32%), Express (n=5; 23%), and iCAST (n=1; 5%). All children had resolution of variceal bleeding or ascites. TIPS revision was required in 9 (45%) children, with a mean of 2.2 revisions. Hepatic encephalopathy developed in 10 children (48%), at a mean of 223.7 days following TIPS placement. During the study, 6 (29%) children underwent liver transplantation. CONCLUSION: TIPS placement in pediatric patients has high technical success with excellent resolution of variceal hemorrhage and ascites. TIPS revision was required in nearly half of the cohort, with hepatic encephalopathy common after shunt placement. PMID- 30291383 TI - Association of miR-146a Gene Polymorphism at loci rs2910164 G/C, rs57095329 A/G, and rs6864584 T/C with Susceptibility to Kawasaki Disease in Chinese Children. AB - OBJECTIVE: To investigate the genetic association of miR-146a gene polymorphisms at loci rs2910164 G/C, rs57095329 A/G, and rs6864584 T/C in patients with Kawasaki disease (KD) and coronary artery lesions (CAL). METHODS: There were 120 patients with KD and 126 healthy subjects in this study. The genotype of loci rs2910164 G/C, rs57095329 A/G, and rs6864584 T/C of miR-146a gene were detected by polymerase chain reaction-sequence-based typing. RESULTS: For miR-146a gene polymorphisms at loci rs2910164 G/C, rs57095329 A/G, and rs6864584 T/C, there were no significant difference of genotype frequencies and allele frequencies between KD group and healthy control group, or between the IVIG-resistant group and IVIG-sensitive group (P > 0.05). In KD with coronary artery lesions (KD-CAL) group, the genotype frequencies of GG were higher than that in KD without coronary artery lesion (KD-WO) group at locus rs2910164 G/C polymorphisms of miR 146a gene (chi2 = 6.660, P = 0.036), patients with KD carried genotype of GG were at 3.636 times higher risk of getting coronary artery lesions than those of non carriers (chi2 = 6.455, P = 0.018, OR = 3.636, 95%CI = 1.280-10.262). While there was no significant difference of allele frequency of G and C between KD-CAL group and KD-WO group (P > 0.05). In KD-CAL group, the allele frequency of A was higher than that in KD-WO group at locus rs57095329 A/G polymorphisms of miR-146a gene (chi2 = 4.745, P = 0.035), carriers with allele A were at 2.422 times higher risk of getting coronary artery lesions than those of non-carriers (chi2 = 4.745, P = 0.035, OR = 2.422, 95%CI = 1.073-5.465), while there was no significant difference of genotype frequency of AA, AG, and GG types between KD-CAL group and KD-WO group (P > 0.05). There was no significant difference of genotype frequencies of TT, TC, and CC types and allele frequencies of T and C types between KD-CAL group and KD-WO group at locus rs6864584 T/C polymorphisms of miR 146a gene (P > 0.05). CONCLUSIONS: The significant association has been found between the genotype and allele frequency of the miR-146a gene loci rs2910164 G/C and rs57095329 A/G, the genotype GG of rs2910164 G/C, and allele A of rs57095329 A/G were risk factors for getting coronary artery lesions. PMID- 30291384 TI - Mortality and Resource Use Following Cardiac Interventions in Children with Trisomy 13 and Trisomy 18 and Congenital Heart Disease. AB - We sought to evaluate the mortality, risk factors for mortality, and resource utilization following cardiac interventions in trisomy 13 (T13) and 18 (T18) children. All T13 and T18 children who underwent a cardiac intervention from January 1999 to March 2015 were identified from the Pediatric Health Information System database. Data collected included demographics, type of congenital heart disease (CHD), cardiac interventions, comorbidities, length of stay (LOS), hospital charges, and deaths (within 30 days). Logistic regression analysis was used to determine factors associated with mortality. There were 49 (47% females) T13 and 140 (67% females) T18 subjects. The two cohorts were similar in distribution for race, geographic region, insurance type, and median household income. The most common CHD in both groups was a shunt lesion followed by conotruncal defects. Compared to T18, the T13 cohort had higher mortality (29% vs. 12%), tracheostomies (12% vs. 4%), gastrostomies (18% vs. 6%), and overall resource use (P < 0.05 for all). White race (OR 0.23, 95% CI 0.06-0.81) in T13 and older age (in weeks) at surgery in T18 (OR 0.75, 95% CI 0.64-0.86) were associated with lower mortality. A select group of T13 and T18 CHD patients can undergo successful cardiac interventions, albeit with a higher mortality and resource use. T13 patients have higher mortality and resource use compared to T18. In T13 and T18 patients, interventions for CHD may be an acceptable and ethical option following a careful individualized selection and counseling by a team of experts. PMID- 30291385 TI - Clinical Effects of Syncope on Disease Severity and Adverse Outcomes in Children with Idiopathic and Heritable Pulmonary Arterial Hypertension. AB - Syncope is more common in children with idiopathic pulmonary arterial hypertension (PAH) than in adults with PAH. Although syncope is associated with a poor prognosis in adult PAH, the clinical effects of syncopal events on disease severity and outcome in children have not been carefully investigated. This study assessed the prevalence of syncope in pediatric PAH and examined its clinical, hemodynamic, and prognostic importance. This retrospective study assessed clinical data, including syncope status, from 78 children (37 girls) with idiopathic and heritable PAH (median age at diagnosis, 11 years). Patients were classified as syncopal or non-syncopal, and clinical data from the two groups were compared. The primary outcome was a composite of lung transplantation and cardiac mortality. Overall, 31 (38%) children had a history of syncope at presentation. Median age at diagnosis, sex ratio, brain natriuretic peptide level, and 6-min walk distance at diagnosis did not differ between groups. The hemodynamic parameters of initial right heart catheterization were similar between the syncope and non-syncope group (mean pulmonary artery pressure, 67 versus 71 mm Hg; cardiac index, 2.9 versus 2.9 l/min/m2, respectively). There was not significantly difference in event-free survival rate between two groups. Although syncopal events are common in children with PAH, our findings suggest that syncope may not be correlated with disease severity or outcome in pediatric PAH. PMID- 30291386 TI - An investigation into the kinematics of magnetically driven droplets on various (super)hydrophobic surfaces and their application to an automated multi-droplet platform. AB - Magnetic actuation on digital microfluidic (DMF) platforms may provide a low cost, less cumbersome alternative for droplet manipulation in comparison to other techniques such as electrowetting-on-dielectric. Precise control of droplets in magnetically driven DMF platforms is achieved using a low-friction surface, magnetically susceptible material/droplet(s), and an applied magnetic field. Superhydrophobic (SH) surfaces offer limited friction for aqueous media as defined by their high water contact angles (WCA) (>150 degrees ) and low sliding angles (<10 degrees ). The low surface friction of such coatings and materials significantly reduces the force required for droplet transport. Here, we present a study that examines several actuation parameters including the effects of particle and particle-free actuation mechanisms, porous and non-porous SH materials, surface chemistry, droplet speed/acceleration, and the presence of surface energy traps (SETs) on droplet kinematics. Automated actuation was performed using an XY linear stepper gantry, which enabled sequential droplet actuation, mixing, and undocking operations to be performed in series. The results of this study are applied to a quantitative fluorescence-based DNA assay in under 2 min. Graphical abstract ?. PMID- 30291387 TI - Alumina/nano-graphite composite as a new nanosorbent for the selective adsorption, preconcentration, and determination of chromium in water samples by EDXRF. AB - Obtaining new nanocomposites with sorption properties towards chromium is highly important not only from the environmental point of view but also for developing eco-friendly methods of chromium determination. The potential use of aluminum oxide-coated nano-graphite (Al2O3/nano-G) as a new nanosorbent in ultrasound assisted dispersive micro-solid-phase extraction (DMSPE) for rapid speciation of trace chromium(III) and chromium(VI) ions in natural water was evaluated. In the developed method, the crucial issue is the new nanocomposite synthesized by coating alumina on a nano-graphite surface with sorption properties. Structural researches of the nanocomposite were carried out by scanning electron microscopy (SEM), powder X-ray diffraction (XRD), and Raman spectroscopy. Maximum adsorption capacity of Al2O3/nano-G towards Cr(III) was 32.8 mg g-1. The influence of the method's factors like pH, sample volumes, contact time, coexisting ions, and humic acid on the recovery of chromium was examined. The nanocomposites have been found to be stable and effective as a sorbent in water with high concentrations of selected cations and anions present in water as well as in water of various pH. Al2O3/nano-G is selective for Cr(III) in presence of Cr(VI). Cr(III) was determined by the developed method, total Cr after reduction of Cr(VI) to Cr(III), and Cr(VI) was calculated as the difference between total Cr and Cr(III). After sorption, the nanocomposite with chromium was collected on 5-mm diameter filters and analyzed by energy-dispersive X-ray fluorescence spectrometry (EDXRF) to determine the chromium concentration. The method was characterized by correlation coefficient 0.999, limit of detection (LOD) 0.04 ng mL-1, and relative standard deviation (RSD) 3.5%. Al2O3/nano-G combined with proposed DMSPE/EDXRF was verified by analysis of certificate reference material of natural water (NIST 1640a). Graphical abstract ?. PMID- 30291389 TI - Simultaneous determination of 14 urinary biomarkers of exposure to organophosphate flame retardants and plasticizers by LC-MS/MS. AB - Organophosphate flame retardants and plasticizers (PFRs) are a group of chemicals widely added to consumer products. PFRs are quickly metabolized in the human body into two types of metabolites, (1) dialkyl and diaryl phosphate esters (DAPs), such as diphenyl phosphate (DPHP) and bis(1,3-dichloro-2-propyl) phosphate (BDCIPP); and (2) hydroxylated PFRs (HO-PFRs), such as 1-hydroxy-2-propyl bis(1 chloro-2-propyl) phosphate (BCIPHIPP) and 2-hydroxyethyl bis(2-butoxyethyl) phosphate (BBOEHEP). Existing analytical methods usually focus on DAPs; therefore, human biomonitoring data on HO-PFRs remain scarce. In this study, an analytical procedure was developed for the simultaneous quantification of multiple PFR metabolites in human urine, covering eight DAPs and six HO-PFRs. Sample preparation was optimized to include all target compounds using Bond-Elut C18 solid-phase extraction cartridges, followed by instrumental analysis based on liquid-chromatography coupled to tandem mass spectrometry (LC-MS/MS). Method performance was validated according to established guidelines and satisfactory results were obtained for all metabolites in terms of recovery, linearity, limits of quantification, precision, and accuracy. Recoveries ranged from 87 to 112%. Method detection limits from 0.002 ng/mL for 2-ethyl-5-hydroxyhexyl diphenyl phosphate (5-HO-EHDPHP) to 0.66 ng/mL for 4-hydroxyphenyl phenyl phosphate (4-HO DPHP). Seven PFR metabolites were frequently detected in a small biomonitoring study (n = 14), among them bis(1,3-dichloro-2-propyl) phosphate (BDCIPP), di-n butyl phosphate (DNBP), 5-HO-EHDPHP, and BBOEHEP. Highest mean concentrations were found for DPHP, 2-ethylhexyl phenyl phosphate (EHPHP), and BCIPHIPP, while 4 HO-DPHP, 5-HO-EHDPHP, and EHPHP were detected in urine for the first time. Overall, the obtained results demonstrate that the developed method can be used for the simultaneous determination of 14 urinary biomarkers of exposure to PFRs. Graphical abstract ?.

PMID- 30291388 TI - Phenotyping the genus Hypericum by secondary metabolite profiling: emodin vs. skyrin, two possible key intermediates in hypericin biosynthesis. AB - A wide range of compounds that occur in the genus Hypericum are listed as effective drugs of natural origin. The main biological activities of several Hypericum representatives are due to the presence of naphthodianthrones, phloroglucinols, and other diverse groups of secondary metabolites that synergistically contribute to their therapeutic effects. The regulation of biosynthesis of hypericin as the key bioactive naphthodianthrone remains uncertain. Here, we present liquid chromatography mass spectrometry-based phenotyping of 17 Hypericum species, the results of which suggest an important role for skyrin and its derivatives in the polyketide pathway that leads to hypericin formation. Moreover, we report for the first time the presence of new metabolites in the genus Hypericum that are related to classes of anthraquinones, their derivatives, and phloroglucinols. As skyrin and other species of anthraquinones are rarely found in higher plants but frequently occur in fungal microorganisms, the obtained results suggest that further research on the synthesis pathways of hypericin and the role of anthraquinone derivatives in plant metabolism should be carried out. The fact that these compounds are commonly synthesized in endophytic fungi and perhaps there is some similarity in the metabolic pathways between these organisms should also be investigated. PMID- 30291391 TI - Robotic-assisted versus standard unicompartmental knee arthroplasty-evaluation of manuscript conflict of interests, funding, scientific quality and bibliometrics. AB - PURPOSE: Robotic-assisted unicompartmental knee arthroplasty (UKA) has gained popularity over the last decade claiming enhanced surgical precision and better joint kinematics, with peer-reviewed publications about this new technology also increasing over the past few years. The purpose of our study was to compare manuscripts about robotic-assisted UKA to those about standard UKA in terms of industry funding, author conflict of interest, scientific quality, and bibliometrics. METHODS: A systematic search using PRISMA guidelines on PubMed and Google Scholar from 2012 to 2016 resulted in 45 papers where robotic technology was performed for UKA and 167 papers that UKA were performed without the assistance of a robot. Between the two groups, we compared (1) rate of manuscripts with reported conflict of interest or industry funding, (2) journal impact factor, (3) level of evidence, and (4) relative citation ratio. RESULTS: Fifty-one percent (23/45) of robotic UKA manuscripts were industry-funded or had authors with financial conflict of interest, compared to 29% ([49/167], p < 0.01) of non-robotic UKA papers. Significantly more robotic UKA papers (24% [11/45] vs 9% [16/167), p < 0.01) were published in journals that were not assigned an impact factor by the Journal Citations Report. There was no difference in regard to bibliometrics or level of evidence. CONCLUSION: Manuscripts in which UKA was performed with the assistance of a robot were more likely to be industry funded or be written by authors with financial conflicts of interest and published in less prestigious journals. There were no differences in scientific quality or influence between the two groups. Readers analyzing published data should be aware of the potential conflicts of interests in order to more accurately interpret manuscripts data and conclusions.

PMID- 30291393 TI - Interleukin-22 and Its Correlation with Disease Activity in Plaque Psoriasis. AB - Psoriasis is a chronic debilitating skin disease with an estimated prevalence reaching 2% of the worldwide population. Psoriatic disease is driven by a network of complicated reciprocal interactions among innate and adaptive mechanisms of immune system with structural components of the skin. Interleukin (IL)-22 mediates keratinocyte proliferation and epidermal hyperplasia, inhibits terminal differentiation of keratinocytes, and induces the production of antimicrobial proteins. The aim of this study was the assessment of IL-22 levels and its correlation with disease activity in plaque psoriasis. The study group included 64 patients with mild, moderate and severe psoriasis. Control group was composed of 24 sex- and age-matched healthy volunteers. IL-22 concentration was assessed in supernatants of T-cell cultures as well as in the plasma of study and control group with the use of ELISA method. Statistical analysis showed that concentration of IL-22 in cultures exposed to staphylococcal enterotoxin B was significantly higher than in control samples (p = 0.005) and cultures treated with IL-12 (p = 0.005). Patients with psoriasis presented significantly higher concentrations of IL-22 than healthy individuals (p = 0.0000001). In conclusion, IL-22 may collaborate with other soluble factors and cells together forming inflammatory circuits that otherwise exist as constitutive or inducible pathways in normal skin and become pathologically amplificated in psoriasis. Targeting IL 22 may be promising as a potential therapeutic for plaque psoriasis. PMID- 30291394 TI - Biomechanical considerations are crucial for the success of tendon and meniscus allograft integration-a systematic review. AB - PURPOSE: This systematic review intends to give an overview of the current knowledge on how allografts used for the reconstruction of cruciate ligaments and menisci are integrated and specifically perform regarding their biomechanical function. METHODS: Two reviewers reviewed the PubMed and Central Cochrane library with focus on the biomechanical integration of tendon ligament and meniscus allografts. The literature search was conducted in accordance with the PRISMA statement for reporting systematic reviews and meta-analyses. RESULTS: The analysed literature on tendon allografts shows that they are more vulnerable to overstretching in the phase of degradation compared to autografts as the revascularization process starts later and takes longer. Therefore, to avoid excessive graft loads, allografts for cruciate ligament replacement should be selected that exhibit much higher failure loads than the native ligaments to counteract the detrimental effect of degradation. Further, placement techniques should be considered that result in a minimum of strain differences during knee joint motion, which is best achieved by near-isometric placement. The most important biomechanical parameters for meniscus allograft transplantation are secure fixation and proper graft sizing. Allograft attachment by bone plugs or by a bone block is superior to circumferential suturing and enables the allograft to restore the chondroprotective biomechanical function. Graft sizing is also of major relevance, because too small grafts are not able to compensate the knee joint incongruity and too large grafts may fail due to extrusion. Only adequate sizing and fixation together can lead to a biomechanically functioning allograft. The objective assessment of the biomechanical quality of allografts in a clinical setting is challenging, but would be highly desirable for monitoring the remodelling and incorporation process. CONCLUSIONS: Currently, indicators like ap stability after ACL reconstruction or meniscal extrusion represent only indirect measures for biomechanical graft integration. These parameters are at best clinical indicators of allograft function, but the overall integration properties comprising e.g. fixation and graft stiffness remain unknown. Therefore, future research should e.g. focus on advanced imaging techniques or other non-invasive methods allowing for in vivo assessment of biomechanical allograft properties. PMID- 30291395 TI - Cells, soluble factors and matrix harmonically play the concert of allograft integration. AB - Implantation of allograft tissues has massively grown over the last years, especially in the fields related to sports medicine. Beside the fact that often no autograft option exists, autograft related disadvantages as donor-site morbidity and prolonged operative time are drastically reduced with allograft tissues. Despite the well documented clinical success for bone allograft procedures, advances in tissue engineering raised the interest in meniscus, osteochondral and ligament/tendon allografts. Notably, their overall success rates are constantly higher than 80%, making them a valuable treatment option in orthopaedics, especially in knee surgery. Complications reported for allografting procedures are a small risk of disease transmission, immunologic rejection, and decreased biologic incorporation together with nonunion at the graft-host juncture and, rarely, massive allograft resorption. Although allografting is a successful procedure, improved techniques and biological knowledge to limit these pitfalls and maximize graft incorporation are needed. A basic understanding of the biologic processes that affect the donor-host interactions and eventual incorporation and remodelling of various allograft tissues is a fundamental prerequisite for their successful clinical use. Further, the importance of the interaction of immunologic factors with the biologic processes involved in allograft incorporation has yet to be fully dissected. Finally, new tissue engineering techniques and use of adjunctive growth factors, cell based and focused gene therapies may improve the quality and uniformity of clinical outcomes. The aim of this review is to shed light on the biology of meniscus, osteochondral and ligament/tendon allograft incorporation and how collection and storage techniques may affect graft stability and embodiment.Level of evidence V. PMID- 30291396 TI - Anatomical reconstruction produced similarly favorable outcomes as repair procedures for the treatment of chronic lateral ankle instability at long-term follow-up. AB - PURPOSE: The aim of this study was to compare long-term outcomes after anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) repair and reconstruction at 5-10 years after surgery. METHODS: Forty-five patients who underwent surgical repair or reconstruction of both ATFL and CFL were retrospectively investigated in this study. American Orthopedic Foot and Ankle Society (AOFAS), Karlsson Score, and Tegner activity scale were used to evaluate the ankle function at a follow-up of 5-10 years. Ultrasound examination was used to evaluate the ATFL and CFL, and MRI was used to evaluate the cartilage. RESULTS: At final follow-up, no patient had recurrent ankle instability. There were no significant differences in AOFAS (92.6 +/- 6.5 vs 89.6 +/- 3.4; n.s.) or Karlsson Score (93 +/- 8.2 vs 90.6 +/- 5.0; n.s.) between the reconstruction group (twenty patients) and the repair group (twenty-five patients) postoperatively. There were also no significant differences in activity level as measured by the Tegner activity score (6 (range 4 to 8) vs 6 (range 5 to 7); n.s.). Five patients in the reconstruction group complained of some tightness of the ankles. Ultrasound showed the reconstructed ligaments maintained good continuity and were thicker than the repaired ligaments. CONCLUSION: Patients in both the repair and the reconstruction cohort had high patient satisfaction with the outcomes and high function and activity levels that indicated recreational sports participation over a long period. LEVEL OF EVIDENCE: III. PMID- 30291397 TI - High tibial osteotomy increases patellofemoral pressure if adverted proximal, while open-wedge HTO with distal biplanar osteotomy discharges the patellofemoral joint: different open-wedge high tibial osteotomies compared to an extra articular unloading device. AB - PURPOSE: Valgus high tibial osteotomy (HTO) and a recently introduced extra articular absorber have been shown to efficiently unload the medial compartment of the knee. However, only little is known about the influence of these treatment modalities on biomechanics of the patellofemoral joint. The purpose of this study was to investigate and compare the impact of different HTO techniques and implantation of an extra-articular absorber on patellofemoral contact forces. METHODS: Fourteen fresh frozen cadaveric knees were tested in a specially designed knee simulator that allowed simulation of isokinetic flexion-extension motions under physiological loading. Mean contact pressure (ACP) and peak contact pressure (PCP) of the patellofemoral joint was measured continuously between 0 degrees and 120 degrees of knee flexion using a pressure sensitive film in the following conditions: native, after biplanar medial open-wedge HTO with 5 degrees and 10 degrees correction angle performing an ascending frontal osteotomy of the tibial tuberosity, and after implantation of an extra-articular absorber system (KineSpring(r)). Including a second testing cycle with a biplanar medial open-wedge HTO with 5 degrees and 10 degrees correction angle performing descending frontal osteotomy of the tibial tuberosity. Values after each procedure were compared to the corresponding values of the native knee. RESULTS: Biplanar proximal osteotomy leaded to a significant increase of retropatellar compartment area contact pressure compared to the first untreated test cycle (Delta 0.04 +/- 0.01 MPa, p = 0.04). Similar results were observed measuring peak contact pressure (Delta 1.41 +/- 0.15 MPa, p = 0.03). With greater correction angle 5 degrees , respectively, 10 degrees peak and contact pressure increased accordingly. In contrast, the biplanar distal osteotomy group showed significant decrease of pressure values (p = 0.004). The extracapsular, extra-articular absorber had no significant influence on pressure levels in the patellofemoral joint. CONCLUSION: HTO with a proximal biplanar osteotomy of the tuberositas tibia significantly increased patellofemoral pressure conditions depending on the correction angle. In contrast a distally directed biplanar osteotomy diminished these effects while implantation of an extracapsular, extra-articular absorber had no influence on the patellofemoral compartment at all. Consequently, patients with varus alignment with additional retropatellar chondropathia should be treated with a distally adverted osteotomy to avoid further undesirable pressure elevation in the patellofemoral joint. PMID- 30291398 TI - Individuals with recurrent ankle sprain demonstrate postural instability and neuromuscular control deficits in unaffected side. AB - PURPOSE: To compare proprioception, postural stability, and neuromuscular control between patients with mechanical laxity and recurrent ankle sprain. METHODS: Among 86 patients with ankle instability, 45 patients had mechanical laxity (mean age 27.2 +/- 7.0 years) and 41 had recurrent ankle sprain (mean age 25.1 +/- 9.2 years). Both the affected and unaffected ankles of each patient were evaluated. Proprioception and neuromuscular control tests were conducted using an isokinetic machine, and postural stability was tested using a postural stabilometry system. RESULTS: Proprioception was not significantly different between the unaffected or affected ankles of the mechanical laxity group compared with those of the recurrent ankle sprain group (n.s). Static and dynamic postural stability and neuromuscular control were similar in the affected ankles between the two groups (n.s). However, postural stability (static, overall: p = 0.009, anterior posterior: p = 0.028, medial-lateral: p = 0.022; dynamic, overall: p = 0.012, anterior-posterior: p = 0.004, medial-lateral: p = 0.001) and neuromuscular control (inversion: p = 0.031, eversion: p = 0.039, dorsiflexion: p = 0.029, plantarflexion: p = 0.035) were significantly decreased in the unaffected ankles of the recurrent ankle sprain group compared with those of the mechanical laxity group. CONCLUSION: The unaffected ankles of the recurrent ankle sprain group showed significant decreases in both postural stability and neuromuscular control compared with the mechanical laxity group. Clinicians and therapists should consider unaffected ankle rehabilitation in patients with recurrent ankle sprain to prevent future sprain events. LEVEL OF EVIDENCE: Case-control study, III. PMID- 30291399 TI - A high level of satisfaction after bicompartmental individualized knee arthroplasty with patient-specific implants and instruments. AB - PURPOSE: Customized Individually Made (CIM) Bicompartmental Knee Arthroplasty (BKA) implants and three-dimensional printed customized instruments are available to fit to each patient's unique anatomy, medial or lateral with patellofemoral. This study aimed to evaluate the clinical outcomes after CIM-BKA. METHODS: Fifty five patients [59 knees; average age, 51 years; standard deviation (SD), 6.8; range 37-65 years] who underwent CIM-BKA were evaluated over an average of 3.8 year follow-up (SD 1.6; range 1-6 years). Forty-one knees underwent BKA combined medial and patellofemoral replacement (BKA-MP) and 18 knees underwent BKA combined lateral with patellofemoral replacement (BKA-LP). Survival rates, the modified Cincinnati Knee Rating Scale, WOMAC, VAS, SF-36, a satisfaction survey, and radiographic evaluation were used to evaluate outcomes. RESULTS: Overall, survival rates were 98% and 92% at 2 and 5 years, respectively. Of 56 knees (95%) that did not fail, all patient-reported functional scores significantly improved post-operatively (P < 0.01), regardless of the previous surgeries, with a high level of satisfaction (51/56 knees, 91%). Radiographically, all the femoral components fit perfectly and 56 knees (95%) of the tibial components fit with less than 2 mm of undercoverage or overhang. Three knees (5%) required the conversion to TKA and 17 knees (29%) required subsequent surgical procedures, of which multiply operated knees had higher rate than virgin knee [14/40 (35%) vs. 3/16 (19%)]. CONCLUSION: CIM-BKA allowed precise fit of the components and provided a significant improvement post-operatively with a high level of satisfaction over short- to mid-term follow-up. This novel CIM-BKA is resurfacing, and does not require 10-mm faceted cuts, being only 3-mm-thick, which preserves bone stock for the future. It may be a promising option for relatively young active patients with bicompartmental osteoarthritis with a longer term follow-up being necessary. LEVEL OF EVIDENCE: IV.

PMID- 30291401 TI - Atmospheric PM2.5-Bound Polycyclic Aromatic Hydrocarbons (PAHs) in Guiyang City, Southwest China: Concentration, Seasonal Variation, Sources and Health Risk Assessment. AB - The polycyclic aromatic hydrocarbons (PAHs) bound to fine particulate matter (PM2.5) can cause long-term adverse health consequences and are a public concern. A total of 144 PM2.5-bound PAHs samples collected from Guiyang City, a typical plateau montane area in southwest China, from September 2012 to August 2013 were investigated to clarify their concentration, distribution, and potential sources. The health exposure risk also was evaluated. The samplers equipped with 90-mm glass fibre filters were operated at a flow rate of 100 L min-1 for 24 h. The concentrations of the 16 PAHs (US EPA priority) were analysed by using ultra performance liquid chromatography equipped with photo diode array detector. Diagnostic ratios and back-trajectories were performed for the 16 PAHs sources apportionment. The results showed that the 16 PAHs ranged from 2.9 to 231 ng m-3 with an annual average of 41 +/- 21 ng m-3. The PAHs concentrations exhibited obvious seasonal variation, with higher levels in winter than in summer. Diagnostic ratios indicated that PAHs mainly originated from the combustion of coal and biomass, followed by the emission of vehicle exhaust. Cluster analyses on back-trajectories illustrated that approximately 34% of the air mass came from abroad, as far as Laos and Vietnam, in summer, whereas more than 90% of the air mass came from domestic sources in winter. The lifetime excess cancer risk from exposure to PAHs was 3.63 * 10-4, approximately 360 times higher than the health guideline (10-6) recommended by the US EPA, reflecting a high risk of cancer. PMID- 30291402 TI - Do non-daily smokers compensate for reduced cigarette consumption when smoking very-low-nicotine-content cigarettes? AB - RATIONALE: The Food and Drug Administration is considering severely restricting the nicotine in cigarettes, to reduce smoking. A study showed that non-daily, intermittent smokers (ITS) randomized to very-low-nicotine-content cigarettes (VLNCCs) reduced their cigarette consumption. OBJECTIVES: To assess whether increased smoking intensity of VLNCCs compensated for some of the reduced cigarette consumption. METHODS: After a 2-week baseline smoking their own-brand cigarettes, 118 ITS were randomized to VLNCCs (~ 1 mg nicotine/g tobacco), and 120 to normal-nicotine-content cigarettes (NNCCs; ~ 16 mg/g) for 10 weeks. Laboratory measures of smoking intensity-total puff volume and carbon monoxide (CO) boost-assessed single cigarettes smoked in up to three laboratory topography sessions. Field measures assessed returned cigarette butts, averaged over up to five 2-week intervals: the mass of tobacco burned (computed from residual mass of butts) and the intensity of smoking (by scanning of returned filters). Analysis was by mixed model random effects models using baseline values as covariates. RESULTS: ITS in the VLNCC group puffed less smoke in topography sessions (-38.50 mL [-75.21, -1.78]; p < 0.04), but showed no difference in CO boost. Participants in the VLNCC group burned 0.02 [0.04, 0.002] grams less tobacco per cigarette (p < 0.03). Analysis of filters showed their smoking intensity declined over time, compared to NNCC participants (p < 0.04). "Cheating" by smoking normal cigarettes did not moderate these effects. CONCLUSIONS: ITS did not increase their smoking intensity when switched to VLNCCs; indeed, their smoking intensity decreased. Reductions in cigarette consumption seen when ITS are switched to VLNCCs were not compensated by increased smoking intensity. PMID- 30291403 TI - Social reinstatement: a rat model of peer-induced relapse. AB - BACKGROUND: An important factor that can lead to drug relapse is to re-associate with drug-using social peers, but there is little literature on the effect of social peers on relapse in animal models. METHODS: The current study used a dual compartment operant conditioning apparatus that allowed adult male rats to respond for cocaine in the presence of a conspecific. In experiment 1, rats were trained to self-administer cocaine in the presence of a social peer that was separated by a wire screen partition and then that peer was used as a reinstatement cue following a period of extinction. In the next experiments, rats were trained on alternating sessions to self-administer cocaine in the presence of one peer and to self-administer saline in the presence of a different peer using either a single-active lever procedure (experiment 2) or a double-active lever procedure (experiment 3). Following extinction of responding in the absence of the peers, the effect of re-exposure to the cocaine- and saline-associated peers on reinstatement of drug seeking was determined. This was tested using both single- and double-active lever procedures. RESULTS: In experiment 1, a peer that was present throughout cocaine self-administration was able to reinstate cocaine seeking following a period of extinction. In experiments 2 and 3, drug seeking was reinstated by the cocaine-associated peer (S+), but not the saline-associated peer (S-). This discrimination occurred when using either the single-active lever procedure or double-active lever procedure. CONCLUSION: These results indicate that a social peer can be used as a discriminative stimulus to signal cocaine availability and that re-introduction of a peer previously paired with cocaine can reinstate cocaine seeking, confirming clinical reports that peer affiliation among abstinent cocaine users is an important determinant of relapse. PMID- 30291404 TI - Comparison of major complications in children after laparoscopy-assisted gastrostomy and percutaneous endoscopic gastrostomy placement: a meta-analysis. AB - PURPOSE: A meta-analysis was performed to compare the rates of the major complications associated with two gastrostomy tube placement techniques in a pediatric population: laparoscopy-assisted gastrostomy (LAG) and percutaneous endoscopic gastrostomy (PEG). METHODS: The PubMed electronic database was queried for comparative studies of the two insertion techniques. The Newcastle-Ottawa scale (NOS) was used for the assessment of the quality and risk of bias in the included studies. The main outcome measure was the frequency of major complications defined as the need for reoperation within 30 days or death. RevMan 5.3, was used, with a p < 0.05 indicating statistical significance. RESULTS: Eight studies including 1550 patients met the inclusion criteria. The risk for major complications was higher in PEG than in LAG 3.86 (95% confidence interval 1.90-7.81; p < 0.0002). The number needed to treat to reduce one major complication by performing LAG instead of PEG was 23. There were no randomized controlled trials. Overall, the quality of the included studies was determined to be unsatisfactory. CONCLUSIONS: PEG placement was associated with a significantly higher risk of major complications compared to LAG placement. Therefore, LAG should be the preferred method for gastrostomy tube placement in children. PMID- 30291405 TI - [Management of the difficult airway : Overview of the current guidelines]. AB - Several national airway task forces have recently updated their recommendations for the management of the difficult airway in adults. Routinely responding to airway difficulties with an algorithm-based strategy is consistently supported. The focus is increasingly not on tools and devices but more on good planning, preparation and communication. In the case of anticipated airway difficulties the airway should be secured when the patient is awake with maintenance of spontaneous ventilation. Unaltered a flexible bronchoscopic intubation technique is advised as a standard of care in such patients. The importance of maintenance of oxygenation is emphasized. Face mask ventilation and the use of supraglottic devices are recommended if unexpected airway difficulties occur. Face mask ventilation may be facilitated and optimised by early administration of neuromuscular blocking agents. If required, in not fastened patients threatened by acute hypoxia, carefully applied and pressure-controlled ventilation may ensure sufficient oxygenation until the airway is secured. Apnoeic oxygen techniques are recommended in high-risk patients and to relieve the time pressure of falling oxygen saturation during decision-making processes. The early use of video laryngoscopy is advised for endotracheal intubation in the case of failed direct laryngoscopy or if intubation is expected to be difficult. For the coverage of cannot intubate-cannot oxygenate scenarios, second generation supraglottic devices and invasive airway access are advocated. The discussion regarding the optimal technique for emergency invasive airway access is still in progress. In the case of uncontrollable respiratory deterioration and progressive hypoxia, the algorithm must be consistently executed and without delay due to ineffective activities (straightforward strategy). Although there is no evidence to support the selection of a particular approach, the importance and the need for a defined airway concept/algorithm in any anesthesia department is fostered. Simplicity and clarity are essential for recall under stressful and time sensitive conditions. The algorithm should be adapted to local conditions and preferences and devices should be limited to a definite number. The acquisition and maintenance of expertise by education and training is demanded.

Ultrasound and computed tomography (CT)-guided kidney biopsy is a safe and accurate method in the diagnostics of renal lesions and can be helpful in the selection of new ablative and pharmaceutical forms of treatment and avoid unnecessary operations. This article describes the clinical indications for an image-guided biopsy and discusses factors which should be considered when performing a biopsy. PMID- 30291406 TI - Transcriptional Regulation Between the Two Global Regulators RovA and CRP in Yersinia pestis biovar Microtus. AB - Yersinia pestis is a dangerous bacterial pathogen that can cause plague. Both RovA and cyclic AMP receptor protein (cAMP-CRP) are required for regulating biofilm- and virulence-related genes in Y. pestis. In this study, the transcriptional regulation between RovA and cAMP-CRP were analyzed by using primer extension, quantitative RT-PCR, LacZ fusion, and electrophoretic mobility shift assay. The results indicated that RovA repressed crp transcription in an indirect manner, while that RovA had no regulatory action on cyaA at the transcriptional level. In addition, cAMP-CRP did not regulate the transcription of rovA. Taken together with our previous results, complex regulatory interactions of RovA, cAMP-CRP, and PhoP/PhoQ in Y. pestis were revealed, which would promote us gain deeper understanding about coordinative modulation of biofilm- and virulence-related regulator genes.

PMID- 30291411 TI - Impact of a prolonged interatrial conduction time for predicting the recurrence of atrial fibrillation after circumferential pulmonary vein isolation of persistent atrial fibrillation. AB - There are some cases that are difficult to cure with only circumferential pulmonary vein isolation (CPVI) of persistent atrial fibrillation (PerAF). Recently, prolonged interatrial conduction times (IACTs), which seem to be associated with progressive remodeled atria, have been reported as a predictor of new-onset AF. This study aimed to investigate the prognostic value of a prolonged IACT for predicting AF recurrences after CPVI of PerAF. One hundred thirteen patients who underwent CPVI without an empirical substrate modification of PerAF were retrospectively analyzed. The IACT was defined as the interval from the earliest P-wave onset on the ECG to the latest activation in the coronary sinus and was measured after achieving the CPVI and conversion to sinus rhythm. During a mean 22.7-month follow-up after the initial procedure, 56 patients (50%) had AF recurrences. Patients with AF recurrence had a longer IACT than those without AF recurrence (p < 0.001). The best discriminative cut-off value for the IACT was 123 ms (sensitivity 53%, specificity 85%). In a Cox multivariate analysis, a prolonged IACT of >= 123 ms was the only independent predictor (hazard ratio: 2.38; 95% confidence interval: 1.36-4.16, p = 0.002) of being associated with the incidence of an AF recurrence. Even after multiple CPVI procedures, patients with an IACT >= 123 ms had a higher AF recurrence rate than those with an IACT < 123 ms (p = 0.002). In conclusion, a prolonged IACT of >= 123 ms may be a useful marker for predicting AF recurrences after both initial and multiple CPVI procedures for PerAF. PMID- 30291412 TI - Effect of tofacitinib on the expression of noggin/BMP-4 and hair growth stimulation in mice. AB - Many hair loss disorders, including non-scaring alopecia, are caused by the arrest of hair follicles at the telogen phase, and the failure to enter the growth phase. Several studies report the efficacy of tofacitinib in promoting hair growth, by mechanisms not precisely known. The aim of this study was to identify other mechanisms by which tofacitinib, applied topically, promotes hair growth. The results showed that histopathological studies in mice treated topically with tofacitinib increased number of hair follicles, ratio of hair follicles in anagen phase, and length of hair infundibulum, and a reduced interfollicular epidermal thickness, compared to DMSO-treated mice. RT-PCR experiments showed significant increases in the expression of noggin (P < 0.05) and BMP4 (P < 0.05) mRNAs, which were greater than those in the vehicle controlled group. Moreover, the expression of noggin and BMP4 mRNAs was significantly higher in the tofacitinib-treated group than in the minoxidil treated group. This study would help understand the efficacy and mechanism by which tofacitinib, applied topically, triggers noggin and BMP4 mRNA expression, both being important molecules involved in the onset of the growth phase of hair growth cycles. PMID- 30291413 TI - Bite injuries caused by transcranial electrical stimulation motor-evoked potentials' monitoring: incidence, associated factors, and clinical course. AB - PURPOSE: The incidence of bite injuries associated with transcranial electrical stimulation motor-evoked potentials monitoring reportedly ranges from 0.13 to 0.19%. However, in clinical practice, bite injuries appear to occur more frequently than previously reported. Our aim was to identify the incidence of and perioperative risk factors associated with bite injuries caused by transcranial electrical stimulation motor-evoked potential monitoring. METHODS: Patients who underwent elective surgery with transcranial electrical stimulation motor-evoked potential monitoring at a single tertiary hospital in Japan between June 2017 and December 2017 were included in this study. All patients were assessed by oral surgeons preoperatively and postoperatively. The associated factors with bite injuries were explored by the univariate analysis. RESULTS: 12 of 186 patients experienced 13 bite injuries, including three lip, six oral mucosa, and four tongue injuries. No patient required suture repair. 11 of 12 patients had uneventful postoperative courses and were cured within 12 postoperative days. One patient with a tongue ulcer and a hematoma had difficulty in oral intake and persistent dysgeusia. Patient severe movement during transcranial electrical stimulation motor-evoked potential monitoring was associated with bite injuries (p = 0.03). CONCLUSIONS: The incidence of bite injuries assessed by oral surgeons was 6.5% in patients with transcranial electrical stimulation motor-evoked potential monitoring, and the patients with severe movement during the monitoring tended to incur bite injuries. In rare cases, transcranial electrical stimulation motor-evoked potential monitoring may cause difficulty in oral intake and dysgeusia. PMID- 30291414 TI - Ultrasound-guided quadratus lumborum block in pediatrics: trans-muscular versus intra-muscular approach. AB - PURPOSE: Quadratus lumborum (QL) block has four approaches. However, there is difference between the four approaches regarding efficacy, safety and adverse effects. The primary objective of this study is to compare the analgesic effect between trans-muscular and intra-muscular approaches of the QL block in pediatric patients for elective lower abdominal surgery. METHODS: 54 patients aged between 1 and 6 years were enrolled. Patients of both genders were selected. The patients were randomly classified into two groups: Group TQL includes patients (27 patients) in whom bilateral QL block was performed using trans-muscular approach, and Group IQL (27 patients), which underwent bilateral QL block using an intra muscular approach. The primary outcome measure was the number of patients who require rescue analgesia in the first 24 h. The secondary outcome measures were FLACC score, heart rate, non-invasive blood pressure at 2, 4, 6, 12, and 24 h postoperatively, and postoperative complications (e.g., quadriceps muscle weakness, local hematoma). RESULTS: In the first 24 h after surgery, 13 patients in the IQL group (48.1%) required rescue analgesia, whereas only five patients in the TQL group (18.5%) required rescue analgesia. The FLACC score was lower in the TQL group than the IQL group at all time intervals up to 24 h postoperatively. In the TQL group, eight patients (29.6%) developed quadriceps weakness; whereas, only one patient (3.7%) in the IQL group developed quadriceps weakness. CONCLUSION: TQL is better than IQL in the analgesic efficacy following the pediatric lower laparotomy. PMID- 30291415 TI - A dicyclic-type electrode-based biofilm reactor for simultaneous nitrate and Cr(VI) reduction. AB - A dicyclic-type electrode-based biofilm-electrode reactor (BER) was investigated for simultaneous removal of nitrate and Cr(VI). In the absence of Cr(VI), almost complete denitrification of 50 mg/L NO3--N was achieved at a very low C/N ratio of 0.8 with the optimal current of 50 mA. Cr(VI) was removed by biological reduction and co-precipitation when Cr(VI) was taken as the only electron acceptor, and the removal efficiencies of Cr(VI) were 99.8%. In the coexistent system of nitrate and Cr(VI), nitrate removal was the result of the cooperation of hydrogenotrophic denitrification and heterotrophic denitrification. The methanol and H2 were also used as electron donors for biological reduction Cr(VI). The denitrification process was slightly inhibited by 1.00 mg/L Cr(VI) and 94.15% removal efficiency was achieved at current = 50 mA and HRT = 8 h. The present results show that the biofilm-electrode reactor is an effective way to simultaneous remove co-contaminants.

AB - The effect of distillery waste product (fusel oil) as an alternative external organic carbon source (EOCS) was investigated in terms of the metabolic properties of denitrifying polyphosphate accumulating organisms (DPAOs). Samples of the non-acclimated biomass were collected from a local full-scale wastewater treatment plant employing A2/O type bioreactors. The acclimated biomass was obtained after cultivation (with fusel oil added) in a bench-scale reactor with a process configuration similar to the full-scale bioreactor. Changes in the functional properties of the biomass were investigated by measuring the phosphate release/uptake rates (PRRs and PURs), and nitrate utilization rates (NURs) with fusel oil in anaerobic-anoxic batch tests. Furthermore, a validated extended Activated Sludge Model no 2d (ASM2d) was used as a supporting tool to analyze the experimental results and estimate the contribution of DPAOs to the overall denitrification. In the non-acclimated biomass with fusel oil, the PRRs, PURs and NURs were low and close to the rates obtained in a reference test without adding EOCS. With the acclimated biomass, the PUR and NUR increased significantly, i.e., 3.5 and 2.7 times, respectively. In the non-acclimated biomass, approximately 60.0 +/- 3.6% and 20.0 +/- 2.2% of the total NUR was attributed to the utilization of endogenous carbon and examined EOCS, respectively. The remaining portion (20% of the total NUR) was attributed to PHA utilization (linked to PO4-P uptake) by DPAOs. With the acclimated biomass, the contribution of the EOCS to the NUR increased to approximately 60%, while the contribution of the endogenous carbon source decreased accordingly. Very accurate predictions of PURs and NURs (R2 = 0.97-1.00) were obtained with the extended ASM2d. Based on model simulations, it was estimated that the activity of DPAOs and denitrifying ordinary heterotrophic organisms corresponded to approximately 20% and 80% of the total NUR, respectively.

Biopsies were obtained from the inner bronchial wall before and a short time again after segmental allergen provocation. In most of the baseline biopsies and in all evaluable biopsies after segmental allergen provocation, the follicular lymphoid tissue was detected by immunohistochemistry in the epithelium of these asthmatic patients. The basic occurrence of the tertiary lymphoid tissue in the bronchial mucosa of mild asthmatics was unexpected and may have consequences for the interpretation of pathophysiology, e.g., as a cause or consequence of bronchial asthma. PMID- 30291418 TI - Age-related changes in the temporal focus and self-referential content of spontaneous cognition during periods of low cognitive demand. AB - An intriguing aspect of human cognition is the unique capacity to mentally retreat from our immediate surroundings to consider perspectives distinct from the here and now. Despite increasing interest in this phenomenon, relatively little is known regarding age-related changes in off-task, self-generated thought (often referred to as "mind-wandering"), particularly under conditions of low cognitive demand. While a number of studies have investigated the temporal orientation of mind-wandering with increasing age, findings have been largely inconsistent. Here, we explored the frequency, temporal focus, and self referential/social content of spontaneous task-unrelated, perceptually decoupled thought in 30 young and 33 healthy older adults using the Shape Expectations task, a validated experimental paradigm in which discrete facets of inner mentation are quantified along a conceptual continuum using open-ended report. Participants also completed the daydreaming subscale of the Imaginal Process Inventory (IPI) as a trait measure of mind-wandering propensity. Significant group differences emerged on the Shape Expectations task, with reduced instances of mind-wandering in the context of elevated task-related thoughts relative to younger adults. In terms of temporal focus, a preponderance of present/atemporal off-task thoughts was evident irrespective of group; however, significantly higher levels of future-oriented thoughts were provided by younger adults, contrasting with significantly higher instances of retrospection in the older group. In addition, older adults displayed significantly fewer incidences of self referential cognition relative to their younger counterparts. Our findings indicate a distinct attenuation of off-task, self-generated thought processes with increasing age, with evidence for a shift in temporal focus and self referential quality, during periods of low cognitive demand.

PMID- 30291422 TI - Age and infection history are revealed by different ornaments in a warbler. AB - Female preference for older or more disease-resistant males are both possible outcomes of parasite-mediated sexual selection, but the extent to which infection alters the development of ornaments to yield signals of male age and health has rarely been explored. In a longitudinal study of 61 male common yellowthroats (Geothlypis trichas), age-related increases in the size of the melanin-based mask and carotenoid-based bib were not correlated among young males, likely owing to differences in how blood parasites affect ornament development. Infection with trypanosomes and hemosporidians in a male's first breeding season was associated with slower growth of the mask; uninfected males attained large masks in their second breeding season, while infected males attained large masks in their third breeding season. In contrast, the bib size of males increased every year regardless of infection. As a consequence, different populations of males are identified by the largest ornaments-older males in the case of bib and a combination of older males and young, uninfected males in the case of mask. Although mask is thus the more informative trait with respect to male health, females prefer large bibs in our population. If infection is opportunistic, young, uninfected males may not possess good genes for parasite resistance but simply good luck, and it may benefit females to prefer older males who are more likely to have withstood prior episodes of selection. A "pure" signal of age may be a more reliable signal of resistance to parasites than an ornament whose expression is modulated by infection. PMID- 30291421 TI - Heterochromatin restricts the mobility of nuclear bodies. AB - Nuclear bodies are relatively immobile organelles. Here, we investigated the mechanisms underlying their movement using experimentally induced interphase prenucleolar bodies (iPNBs). Most iPNBs demonstrated constrained diffusion, exhibiting infrequent fusions with other iPNBs and nucleoli. Fusion events were actin-independent and appeared to be the consequence of stochastic collisions between iPNBs. Most iPNBs were surrounded by condensed chromatin, while fusing iPNBs were usually found in a single heterochromatin-delimited compartment ("cage"). The experimentally induced over-condensation of chromatin significantly decreased the frequency of iPNB fusion. Thus, the data obtained indicate that the mobility of nuclear bodies is restricted by heterochromatin. PMID- 30291423 TI - Comparison of outcome in stroke patients admitted during working hours vs. off hours; a single-center cohort study. AB - INTRODUCTION: We aimed to disprove an in-hospital off-hour effect in stroke patients by adjusting for disease severity and poor prognostic findings on imaging. PATIENTS AND METHODS: Our study included 5378 patients from a single center prospective stroke registry of a large teaching hospital in the Netherlands, admitted between January 2003 and June 2015. Patients were categorized by admission time, off-hours (OH) or working hours (WH). The in hospital mortality, 7-day mortality, unfavorable functional outcome (modified Rankin scale > 2) and discharge to home were analyzed. Results were adjusted for age, sex, stroke severity (NIHSS score) and unfavorable findings on imaging of the brain (midline shift and dense vessel sign). RESULTS: Overall, 2796 patients (52%) were admitted during OH, which had a higher NIHSS score [3 (IQR 2-8) vs. 3 (IQR 2-6): p < 0.01] and had more often a dense vessel sign at admission (7.9% vs. 5.4%: p < 0.01). There was no difference in mortality between the OH-group and WH-group (6.2% vs. 6.0%; p = 0.87). The adjusted hazard ratio of in-hospital mortality during OH was 0.87 (95% CI: 0.70-1.08). Analysis of 7-day mortality showed similar results. Unadjusted, the OH-group had an unfavorable outcome [OR: 1.14 (95% CI: 1.02-1.27)] and could less frequently be discharged to home [OR: 1.16 (95% CI: 1.04-1.29)], which was no longer present after adjustment. DISCUSSION AND CONCLUSIONS: The overall outcome of stroke patients admitted to a large Dutch teaching hospital is not influenced by time of admission. When studying OH effects, adjustment for disease severity and poor prognostic findings on imaging is crucial before drawing conclusions on staffing and material. PMID- 30291424 TI - Cerebral small vessel disease: neuroimaging markers and clinical implication. AB - Cerebral small vessel disease (CSVD) is a broad category of cerebrovascular diseases which primarily affect the perforating arterioles, capillaries and venules with multiple distinct etiologies. In spite of distinctive pathogenesis, CSVD shares similar neuroimaging markers, including recent small subcortical infarct, lacune of presumed vascular origin, white matter hyperintensity of presumed vascular origin, perivascular space and cerebral microbleeds. The radiological features of neuroimaging markers are indicative for etiological analysis. Furthermore, in sporadic arteriosclerotic pathogenesis associated CSVD, the total CSVD burden is a significant predictor for stroke events, global cognitive impairment, psychiatric disorders and later life quality. This review aims to summarize the radiological characteristics as well as the clinical implication of CSVD markers and neuroimaging interpretation for CSVD symptomatology. PMID- 30291425 TI - Hypoalgesia after bicycling at lactate threshold is reliable between sessions. AB - PURPOSE: Exercise decreases pain sensitivity known as exercise-induced hypoalgesia (EIH). However, the consistency of EIH after an acute exercise protocol based on subjective ratings of perceived exertion has been questioned. Objectives were to compare the effect on pressure pain thresholds (PPTs) after bicycling with work-rate at the lactate threshold compared with quiet rest, and investigate between-session reliability of EIH. METHODS: Thirty-four healthy subjects completed three sessions with 7 days in-between. In session 1, the lactate threshold was determined via blood samples (finger-tip pinprick, > 2 mmol/l increase from warm-up) during a graded bicycling task. In session 2 and 3, all subjects performed (1) 15 min quiet-rest, and (2) 15 min bicycling (work-rate corresponding to the lactate threshold) in the two identical sessions. PPTs at the quadriceps and trapezius muscles were assessed before and after both conditions. Reliability was assessed by intraclass correlations (ICCs). RESULTS: Bicycling increased quadriceps PPT compared with quiet-rest in both sessions [mean difference: 45 kPa (95% CI 19-72 kPa), P = 0.002]; however, the increase in trapezius PPT was not significant after exercise. The EIH responses demonstrated fair between-session test-retest reliability (quadriceps: ICC = 0.45; trapezius: ICC = 0.57, P < 0.05), and agreement in EIH responders and non-responders between sessions was significant (quadriceps: kappa = 0.46 and trapezius: kappa = 0.43, P < 0.05). CONCLUSIONS: In conclusion, bicycling at the lactate threshold increased PPT at the exercising muscle with fair reliability of the local EIH response. The results have implications for future EIH studies in subjects with and without pain and for clinicians who design exercise programs for pain relief. PMID- 30291426 TI - iNuc-ext-PseTNC: an efficient ensemble model for identification of nucleosome positioning by extending the concept of Chou's PseAAC to pseudo-tri-nucleotide composition. AB - Nucleosome is a central element of eukaryotic chromatin, which composes of histone proteins and DNA molecules. It performs vital roles in many eukaryotic intra-nuclear processes, for instance, chromatin structure and transcriptional regulation formation. Identification of nucleosome positioning via wet lab is difficult; so, the attention is diverted towards the accurate intelligent automated prediction. In this regard, a novel intelligent automated model "iNuc ext-PseTNC" is developed to identify the nucleosome positioning in genomes accurately. In this predictor, the sequences of DNA are mathematically represented by two different discrete feature extraction techniques, namely pseudo-tri-nucleotide composition (PseTNC) and pseudo-di-nucleotide composition. Several contemporary machine learning algorithms were examined. Further, the predictions of individual classifiers were integrated through an evolutionary genetic algorithm. The success rates of the ensemble model are higher than individual classifiers. After analyzing the prediction results, it is noticed that iNuc-ext-PseTNC model has achieved better performance in combination with PseTNC feature space, which are 94.3%, 93.14%, and 88.60% of accuracies using six fold cross-validation test for the three benchmark datasets S1, S2, and S3, respectively. The achieved outcomes exposed that the results of iNuc-ext-PseTNC model are prominent compared to the existing methods so far notifiable in the literature. It is ascertained that the proposed model might be more fruitful and a practical tool for rudimentary academia and research.

PMID- 30291429 TI - Kidney as modulator and target of "good/bad" HDL. AB - The strong inverse relationship between low levels of high-density lipoproteins (HDLs) and atherosclerotic cardiovascular disease (CVD) led to the designation of HDL as the "good" cholesterol. The atheroprotection is thought to reflect HDL's capacity to efflux cholesterol from macrophages, followed by interaction with other lipoproteins in the plasma, processing by the liver and excretion into bile. However, pharmacologic increases in HDL-C levels have not led to expected clinical benefits, giving rise to the concept of dysfunctional HDL, in which increases in serum HDL-C are not beneficial due to lost or altered HDL functions and transition to "bad" HDL. It is now understood that the cholesterol in HDL, measured by HDL-C, is neither a marker nor the mediator of HDL function, including cholesterol efflux capacity. It is also understood that besides cholesterol efflux, HDL functionality encompasses many other potentially beneficial functions, including antioxidant, anti-inflammatory, antithrombotic, anti-apoptotic, and vascular protective effects that may be critical protective pathways for various cells, including those in the kidney parenchyma. This review highlights advances in our understanding of the role kidneys play in HDL metabolism, including the effects on levels, composition, and functionality of HDL particles, particularly the main HDL protein, apolipoprotein AI (apoAI). We suggest that normal apoAI/HDL in the glomerular filtrate provides beneficial effects, including lymphangiogenesis, that promote resorption of renal interstitial fluid and biological particles. In contrast, dysfunctional apoAI/HDL activates detrimental pathways in tubular epithelial cells and lymphatics that lead to interstitial accumulation of fluid and harmful particles that promote progressive kidney damage. PMID- 30291430 TI - In vitro experimental models for examining the skeletal muscle cell biology of exercise: the possibilities, challenges and future developments. AB - Exercise provides a cornerstone in the prevention and treatment of several chronic diseases. The use of in vivo exercise models alone cannot fully establish the skeletal muscle-specific mechanisms involved in such health-promoting effects. As such, models that replicate exercise-like effects in vitro provide useful tools to allow investigations that are not otherwise possible in vivo. In this review, we provide an overview of experimental models currently used to induce exercise-like effects in skeletal muscle in vitro. In particular, the appropriateness of electrical pulse stimulation and several pharmacological compounds to resemble exercise, as well as important technical considerations, are addressed. Each model covered herein provides a useful tool to investigate different aspects of exercise with a level of abstraction not possible in vivo. That said, none of these models are perfect under all circumstances, and the choice of model (and terminology) used should be informed by the specific research question whilst accounting for the several inherent limitations of each model. Further work is required to develop and optimise the current experimental models used, such as combination with complementary techniques during treatment, and thereby improve their overall utility and impact within muscle biology research. PMID- 30291431 TI - Carbocisteine stimulated an increase in ciliary bend angle via a decrease in [Cl ]i in mouse airway cilia. AB - Carbocisteine (CCis), a mucoactive agent, is widely used to improve respiratory diseases. This study demonstrated that CCis increases ciliary bend angle (CBA) by 30% and ciliary beat frequency (CBF) by 10% in mouse airway ciliary cells. These increases were induced by an elevation in intracellular pH (pHi; the pHi pathway) and a decrease in the intracellular Cl- concentration ([Cl-]i; the Cl- pathway) stimulated by CCis. The Cl- pathway, which is independent of CO2/HCO3-, increased CBA by 20%. This pathway activated Cl- release via activation of Cl- channels, leading to a decrease in [Cl-]i, and was inhibited by Cl- channel blockers (5 nitro-2-(3-phenylpropylamino) benzoic acid and CFTR(inh)-172). Under the CO2/HCO3 -free condition, the CBA increase stimulated by CCis was mimicked by the Cl--free NO3- solution. The pHi pathway, which depends on CO2/HCO3-, increased CBF and CBA by 10%. This pathway activated HCO3- entry via Na+/HCO3- cotransport (NBC), leading to a pHi elevation, and was inhibited by 4,4'-diisothiocyano-2,2' stilbenedisulfonic acid. The effects of CCis were not affected by a protein kinase A inhibitor (1 MUM PKI-A) or Ca2+-free solution. Thus, CCis decreased [Cl ]i via activation of Cl- channels including CFTR, increasing CBA by 20%, and elevated pHi via NBC activation, increasing CBF and CBA by 10%. PMID- 30291434 TI - Mitochondrial disorder mimicking rheumatoid disease. AB - OBJECTIVE: Mitochondrial disorders (MIDs) may manifest phenotypically with a plethora of clinical features, but polyarthralgia and cutaneous lesions are still infrequently reported and recognized as phenotypic manifestations of a MID. CASE REPORT: The patient is a 27-year-old Caucasian female with a history of preterm birth, symptomatic myopathy, and polyarthralgia since infancy, followed by multiple endocrinopathies including pituitary insufficiency, cardiac conduction defects, nephrolithiasis, aseptic chronic pancreatitis and sialadenitis, anemia, hyperlipidemia, and dysmorphic features. The patient reported to have profited from hydrocortisone and long-term chloroquine, but hardly from long-term immunosuppression with various immunosuppressants. The diagnosis MID was established upon the multiorgan nature of the disease, presence of core clinical features of a MID, and a muscle biopsy indicative of a mitochondrial defect. The family history was positive for mitochondrial features in the mother and grandmother from the mother's side. CONCLUSION: Seronegative and non-destructive polyarthralgia and unexplained cutaneous features mimicking cutaneous lupus should be considered as a phenotypic feature of a multisystem MID (mitochondrial multiorgan disorder syndrome, MIMODS). Mitochondrial metabolic defects may trigger secondary immune reactions. Core clinical features of a non-specific MID with infantile onset include symptomatic myopathy, endocrine abnormalities, cardiac conduction defects, dysmorphism, hyperlipidemia, anemia, and nephrolithiasis.

AB - The causes of diseases and disorders of the immune system, which lead to the development of systemic lupus erythematosus (SLE), are not yet completely understood; however, it is known that there are various mechanisms, which can lead to SLE. The development of the disease is based on an underlying genetic disposition but is first triggered by exposure to environmental factors, such as sunburn, viral infections or vitamin D deficiency. Disease flares can also be triggered by environmental factors. Many disease manifestations are caused by pathogenic autoantibodies; hence, B-cells and plasma cells play a critical role in the pathogenesis of SLE. This review provides an overview of the most frequent factors leading to the development of SLE and describes the key mechanisms of its pathogenesis. PMID- 30291432 TI - Implication of non-coding PAX6 mutations in aniridia. AB - There is an increasing implication of non-coding regions in pathological processes of genetic origin. This is partly due to the emergence of sophisticated techniques that have transformed research into gene expression by allowing a more global understanding of the genome, both at the genomic, epigenomic and chromatin levels. Here, we implemented the analysis of PAX6, whose coding loss-of-function variants are mainly implied in aniridia, by studying its non-coding regions (untranslated regions, introns and cis-regulatory sequences). In particular, we have taken advantage of the development of high-throughput approaches to screen the upstream and downstream regulatory regions of PAX6 in 47 aniridia patients without identified mutation in the coding sequence. This was made possible through the use of custom targeted resequencing and/or CGH array to analyze the entire PAX6 locus on 11p13. We found candidate variants in 30 of the 47 patients. 9/30 correspond to the well-known described 3' deletions encompassing SIMO and other enhancer elements. In addition, we identified numerous different variants in various non-coding regions, in particular untranslated regions. Among these latter, most of them demonstrated an in vitro functional effect using a minigene strategy, and 12/21 are thus considered as causative mutations or very likely to explain the phenotypes. This new analysis strategy brings molecular diagnosis to more than 90% of our aniridia patients. This study revealed an outstanding mutation pattern in non-coding PAX6 regions confirming that PAX6 remains the major gene for aniridia.

PMID- 30291435 TI - New iPAD-based test for the detection of color vision deficiencies. AB - PURPOSE: To develop and validate a new iPad-based color vision test (Optopad). METHODS: A total of 341 student eyes were enrolled in a first comparative study between Optopad and the Isihara tests. In a second comparative study, Optopad vs. the Farnworth-Munsell test (FM 100H), a total of 66 adult eyes were included. Besides the agreement between tests, the correlation between FM 100H and Optopad outcomes were investigated. Multiple regression analysis was used to predict the total error score (TES) from contrast thresholds measured with the Optopad test. RESULTS: The Ishihara and Optopad tests detected the same anomalous patients. Concerning FM 100H vs. Optopad, 10 subjects were diagnosed as anomalous with both tests, 3 mild anomalous cases based on TES were classified as normal with Optopad, and 2 anomalous subjects based on Optopad test showed normal TES values. Statistically significant correlations of TES and partial error red-green (PTESRG) with thresholds measured with the red-green Optopad stimuli were found. A multiple quadratic regression model was obtained relating TES and chromatic contrast values from Optopad (R2 = 0.855), with only 13 cases showing residuals of >= 25 units. CONCLUSIONS: The design and implementation of a chromatic contrast discrimination test has been carried out, with promising clinical results. This test seems to provide comparable outcomes to those obtained with Ishihara and FM 100H tests. PMID- 30291437 TI - The significance of tissue biopsy for fungi in necrotizing otitis externa. AB - INTRODUCTION: The conventional treatment for necrotizing otitis externa (NOE) is prolonged anti-pseudomonas therapy, with surgical treatment in non-responsive patients. The aim of the present study is to describe the course of management of patients with non-responsive NOE undergoing hyperbaric oxygen therapy (HBOT), and to investigate the importance of tissue biopsy for fungi in this group of patients. MATERIALS AND METHODS: A retrospective study conducted between January 2010 and December 2013 at an Otolaryngology Head and Neck Surgery Department. Included were all 52 patients with NOE referred to our Medical Centre for further treatment including HBOT. RESULTS: Fifty-two consecutive patients, 29 men and 23 women, with a mean age of 70.6 years, were included in our study. Twenty seven (51.9%) underwent surgical debridement. No significant difference was found between the group having surgical intervention, and those who did not, with regard to sex, age, comorbidities, cranial nerve involvement or laboratory results. However, those who had surgical intervention had a statistically significant higher rate of fungal infection (P = 0.049). After completing 7 weeks of HBOT, a significantly lower WBC count was observed in the fungus-infected group (7000 vs 7.800, P = 0.03), and a tendency towards lower CRP levels in the fungus-infected group (16 vs 58, P = 0.087). CONCLUSION: Patients with NOE should have a comprehensive surgical intervention when delayed healing is observed, because proper fungal culturing might change the course of treatment and improve prognosis. LEVEL OF EVIDENCE: 4. PMID- 30291438 TI - Non-monotonic accumulation of spike time variance during membrane potential oscillations. AB - A spike-phase neural code has been proposed as a mechanism to encode stimuli based on the precise timing of spikes relative to the phase of membrane potential oscillations. This form of coding has been reported in both in vivo and in vitro experiments across several regions of the brain, yet there are concerns that such precise timing may be compromised by an effect referred to as variance accumulation, wherein spike timing variance increases over the phase of an oscillation. Here, we provide a straightforward explanation of this effect based on the theoretical spike time variance. The proposed theory is consistent with recordings of mitral neurons. It shows that spike time variance can increase in a nonlinear fashion with spike number, in a way that is dependent upon the frequency and amplitude of the oscillation. Further, non-monotonic accumulation of variance can arise from different combinations of oscillation parameters. Nonlinear accumulation sometimes leads to lower variance than that of a mean rate matched homogeneous Poisson process, particularly for spikes that occur in later phases of oscillation. However, such an advantage is limited to a narrow range of oscillation amplitudes and frequencies. These results suggest fundamental constraints on spike-phase coding, and reveal how certain spikes in a sequence may exhibit increased firing time precision relative to their neighbors.

PMID- 30291440 TI - Linked color imaging can enhance recognition of early gastric cancer by high color contrast to surrounding gastric intestinal metaplasia. AB - BACKGROUND: Linked color imaging (LCI) increases the visibility of early gastric cancers, which may be associated with characteristic findings including background purple mucosae. These lesions are found in areas of chronic gastritis and surrounding mucosa. The aim of this study is to objectively characterize these lesions by color differences and color component values using LCI. METHODS: Fifty-two patients with early gastric cancer were enrolled. Color differences were calculated prospectively in malignant lesions and adjacent mucosa and compared with histological findings in resected specimens. Color component values of L*, a*, and b* were compared between purple and non-purple mucosae in areas of chronic gastritis. Based on histological findings, the accuracy of identifying gastric intestinal metaplasia was calculated. RESULTS: Cancers and surrounding mucosa in 74% of lesions had similar colors using white light imaging (WLI), whereas purple mucosa surrounded part or all of cancers appearing orange-red, orange or orange-white using LCI. Greater color differences were seen using LCI compared to WLI, including flat-type cancers, leading to higher contrast. The surrounding purple mucosa corresponded histologically to intestinal metaplasia, facilitating the identification of malignant lesions. Forty lesions (83%) with purple mucosa and eight lesions (17%) with non-purple mucosa in areas of chronic gastritis were diagnosed as intestinal metaplasia by biopsy (83% accuracy). Color component values of purple mucosa differ significantly from those of non-purple mucosae. CONCLUSIONS: LCI images have higher color contrast between early gastric cancers and surrounding mucosa compared to WLI. A characteristic purple color around gastric cancers using LCI represents intestinal metaplasia. PMID- 30291441 TI - Impact of FAAH genetic variation on fronto-amygdala function during emotional processing. AB - Recent translational studies identified a common endocannabinoid polymorphism, FAAH C385A, in the gene for the fatty acid amide hydrolase (FAAH). This polymorphism alters endocannabinoid anandamide levels, which are known to be involved in the fronto-amygdala circuitry implicated in mood regulation and anxiety-like behaviors. While it has been shown that the variant that selectively enhances fronto-amygdala connectivity at rest is associated with decreased anxiety-like behaviors, no study so far has investigated whether this finding of FAAH-related differential plasticity extends to task-related differential functional expression and regulation during negative emotional processing. Using an imaging genetics approach, this study aimed to replicate and extend prior findings by examining functional activity and task-related connectivity in fronto amygdala regions during emotion reactivity and emotional down-regulation of negative affect. Therefore, 48 healthy young adults underwent a functional MRI resting state measurement, completed an emotion regulation paradigm and provided self-reports on anxiety and use of emotion regulation strategies. In line with previous studies, preliminary evidence suggests that A-allele carriers demonstrate stronger fronto-amygdala connectivity during rest. In addition, exploratory whole-brain analyses indicate differential functional activity of A allele carriers during emotion reactivity and emotion regulation. There were no associations with anxiety-related self-reports and use of emotional regulation strategies. Further research using larger samples and polygenic approaches is indicated to clarify the precise role and its underlying mechanisms in emotion processing. PMID- 30291442 TI - Asparagine alters action potential parameters in single plant cell. AB - Effect of amino acid L-asparagine on electrical signalling of single Nitellopsis obtusa (Characeaen) cell was investigated using glass-microelectrode technique in current-clamp and voltage-clamp modes. Cell exposure for 30 min to 0.1 mM and 1 mM of asparagine resulted in changes of electrically stimulated action potential (AP) parameters in comparison to standard conditions. Results indicate that asparagine acts in dose-dependent manner: increases AP amplitude by hyperpolarizing AP threshold potential (Eth), prolongs action potential repolarization, increases maximum Cl- efflux amplitude along with the increase of activation and inactivation durations. Presented findings provide new aspects of exogenous amino acids' effect on plants' electrical signalling with emphasis on separate single plant cell excitability and AP characteristics. PMID- 30291443 TI - Evolution of light-independent protochlorophyllide oxidoreductase. AB - The nonhomologous enzymes, the light-independent protochlorophyllide reductase (DPOR) and the light-dependent protochlorophyllide oxidoreductase (LPOR), catalyze the reduction of protochlorophyllide (Pchlide) to chlorophyllide (Chlide) in the penultimate step of biosynthesis of chlorophyll (Chl) required for photosynthetic light absorption and energy conversion. The two enzymes differ with respect to the requirement of light for catalysis and oxygen sensitivity. DPOR and LPOR initially evolved in the ancestral prokaryotic genome perhaps at different times. DPOR originated in the anoxygenic environment of the Earth from nitrogenase-like enzyme of methanogenic archaea. Due to the transition from anoxygenic to oxygenic photosynthesis in the prokaryote, the DPOR was mostly inactivated in the daytime by photosynthetic O2 leading to the evolution of oxygen-insensitive LPOR that could function in the light. The primary endosymbiotic event transferred the DPOR and LPOR genes to the eukaryotic phototroph; the DPOR remained in the genome of the ancestor that turned into the plastid, whereas LPOR was transferred to the host nuclear genome. From an evolutionary point of view, several compelling theories that explain the disappearance of DPOR from several species cutting across different phyla are as follows: (i) pressure of the oxygenic environment; (ii) change in the light conditions and temperature; and (iii) lineage-specific gene losses, RNA editing, and nonsynonymous substitution. Certain primary amino acid sequence and the physiochemical properties of the ChlL subunit of DPOR have similarity with that of LPOR suggesting a convergence of these two enzymes in certain evolutionary event. The newly obtained sequence data from different phototrophs will further enhance the width of the phylogenetic information on DPOR.

AB - BACKGROUND: The number of colorectal cancer cases is increasing, and so the number of laparoscopic colectomy procedures being performed is also increasing, leading to an increased workload for surgeons. However, operating for prolonged time periods may cause surgeons to lose their concentration and develop fatigue. We hypothesized that there is a time-of-day variation in outcome for patients with colorectal cancer who undergo laparoscopic colectomy. The present study aimed to compare the operative outcome between laparoscopic colectomy for colorectal cancer performed in the morning versus the afternoon. METHODS: This was a single-center, retrospective study. All 1961 consecutive patients who underwent laparoscopic surgery for colorectal cancer between 2007 and 2017 were included; 1006 of these patients underwent morning surgery, while 955 underwent afternoon surgery. These patients were analyzed using propensity score matching, giving 791 patients in each group. The short- and long-term outcomes in both groups were compared. RESULTS: Before propensity score matching, the morning group had a larger mean tumor size than the afternoon group (30 cm vs 35 cm; P = 0.0035). After matching, the two groups did not significantly differ in any patient characteristics. Compared with the afternoon group, the morning group had a significantly lesser incidence of intra-operative organ injury (0.25% vs 1.13%; P = 0.027), and a significantly greater incidence of post-operative abdominal abscess (2.03% vs 0.75% P = 0.028). The incidences of other complications and morbidities were similar in both groups. The median operative time in the morning group (201 min) was significantly longer than that in the afternoon group (193 min; P = 0.0124). The two groups did not differ in 5-year overall survival rates and 5-year disease-free rates within any disease stage. CONCLUSIONS: Surgical start times are correlated with surgical outcomes. Our data will help to ensure the safest possible surgeries. PMID- 30291445 TI - The frequency and diagnostic accuracy of hand deformities in Parkinson's disease. AB - Hand deformities are well-known abnormalities observed in patients with Parkinson's disease (PD). We determined the frequency and diagnostic accuracy of hand deformities in PD. We studied 44 consecutive patients with PD, 44 age- and gender-matched normal controls and 22 patients with essential tremor (ET). By means of photographs taken in both hands of all participants, the degree of metacarpophalangeal (MCP) joint flexion was quantified by software and by blinded evaluations using a semiquantitative scale from the radial aspect, we grouped hands into four grades. The presence of classical striatal hand deformity (CSHD), defined as MCP joint flexion, proximal interphalangeal joint extension and distal interphalangeal joint flexion was also evaluated. Patients with PD had a higher frequency of MCP joint flexion and CSHD compared to normal controls and patients with ET. Mean MCP joint flexion was higher in both hands in patients with PD: 20.8 degrees vs. normal controls (3.3 degrees -3.9 degrees ) and patients with ET (2.8 degrees -6.3 degrees ), P = 0.001. Concordance between evaluators for MCP joint flexion was fair: kappa = 0.34 (P < 0.001), but poor for CSHD: kappa = 0.142-0.235 (P < 0.05). A right hand MCP joint flexion of 12.5 degrees and left hand of 10.5 degrees , showed similar sensitivity (0.70) and specificity (between 0.75 and 0.80) than any degree of MCP joint flexion for the diagnosis of PD. CSHD had a sensitivity (0.60-0.80) and specificity (0.78-0.98) for the diagnosis of PD. Hand deformities are commonly observed in patients with PD, they may aid in the diagnosis of PD when compared to normal controls and patients with ET.

Recently, a new class of salts termed supersalts was reported, each of which contains a superalkali and a superhalogen that mimic an alkali metal cation and a halogen anion, respectively. Using three different functionals, namely B3LYP, wB97X, and M06-2X, we theoretically investigated a new subset of supersalts composed of Zintl-based superalkalis and inorganic superhalogens via computational modeling. The calculated dipole moment and first-order hyperpolarizability values for these supersalts indicate that they present nonlinear optical (NLO) behavior. The supersalts of Zintl superalkalis (Ca2P7, Sr2P7, Ba2P7) and superhalogens (BF4, BeF3, NO3) studied here were found to be stable. Graphical Abstract Using the first-principles calculation, a new class of supersalts by using Zintl-based superalkalis and inorganic superhalogens has been designed. PMID- 30291448 TI - Microbiota disruption leads to reduced cold tolerance in Drosophila flies. AB - It is now acknowledged that bacteria from gut microbiota deeply interact with their host by altering many physiological traits. Such interplay is likely to consequently affect stress tolerance. Here, we compared cold and heat tolerance of Drosophila melanogaster flies with undisrupted (control (Co)) versus disrupted gut microbiota (dechorionated eggs (De)). The disrupting treatment strongly reduced bacterial load in flies' guts, though 16S sequencing analysis did not evidence strong diversity changes in the remaining bacterial community. Both chill coma recovery and acute cold survival were repeatedly lower in De than in Co flies under our experimental conditions. However, heat tolerance was not consistently affected by gut disruption. Our results suggest that microbiota related effects on the host can alter ecologically relevant traits such as thermal tolerance. PMID- 30291447 TI - A salamander's toxic arsenal: review of skin poison diversity and function in true salamanders, genus Salamandra. AB - Terrestrial salamanders of the genus Salamandra represent one of the most prominent groups of amphibians. They are mainly distributed across Europe but also reach Northern Africa and the Near East. Members of the six currently accepted species have long been known to be poisonous; however, work on their toxins was mostly published in German language, and therefore, many nuances of these studies have remained hidden from the majority of herpetologists and toxinologists. Several Salamandra species are called fire salamanders due to their highly contrasted, black-yellow colouration which probably serves to deter predators, although thorough evidence for aposematism in Salamandra is still lacking. Salamandra skin toxins do not only represent a potent antipredator defence but may also have antimicrobial effects. A better understanding of this dual function of Salamandra skin secretions is of utmost importance in the face of the emergence of a fungal disease causing catastrophic declines of fire salamanders in Central Europe, caused by the fungus Batrachochytrium salamandrivorans. In this review, we summarize the knowledge on Salamandra toxins, providing a list of the compounds so far isolated from their secretion and focusing on the bioactivity of the major compounds in Salamandra secretions, the steroidal alkaloids. We identify priorities for future research, including a screening of co-occurrence of steroidal alkaloids and tetrodotoxins in salamandrids, chemical characterization of already identified novel steroidal compounds, elucidation of the presence and role of peptides and proteins in the secretion, and experimental in vitro and in vivo study of the interactions between bioactive compounds in Salamandra skin secretions and cutaneous fungal and bacterial pathogens. PMID- 30291449 TI - The first Gondwanan borioteiioid lizard and the mid-Cretaceous dispersal event between North America and Africa. AB - Borioteiioidea are an enigmatic group of Cretaceous lizards widely distributed in northern continents (Laurasia). Here, we describe the first borioteiioid lizard from Gondwana, represented by a new species of the polyglyphanodontine genus Bicuspidon, B. hogreli sp. nov., from the Cenomanian Kem Kem beds of Morocco. The discovery of Bicuspidon hogreli sp. nov., which is one of the oldest known member of Polyglyphanodontini, challenges previous assumptions on the center of origin and dispersal of the group. In addition, the known distribution of Bicuspidon (Cenomanian of Utah and Morocco, and Santonian-Maastrichtian of eastern Europe) suggests a complex palaeobiogeographical history for the genus. The existence of a terrestrial dispersal route persisting during the whole Early Cretaceous between North America and Africa is hypothesized to explain some similarities observed between the Cenomanian squamate assemblages of these two continents. Alternatively, dispersal between the two landmasses may have occurred by transatlantic rafting. During the Cenomanian-Santonian interval, Bicuspidon colonized the European archipelago probably from North Africa, like many "Eurogondwanan" taxa. PMID- 30291450 TI - Long noncoding RNA and gene expression analysis of melatonin-exposed Liaoning cashmere goat fibroblasts indicating cashmere growth. AB - Cashmere produced from Liaoning cashmere goat is highly valuable. Melatonin is an important factor affecting cashmere growth and can regulate the growth cycle via effects on gene expression. Long noncoding RNAs (lncRNAs) regulate gene expression, but detailed studies of their effect on hair growth are lacking. To explore how lncRNA mediates the effects of melatonin on cashmere growth, we used RNA-Seq including a control condition (C) and three melatonin treatments (1.0 g/L 24 h (M1_24H), 0.2 g/L 24 h (M2_24H), 0.2 g/L 72 h (M2_72H)). M1_24H, M2_24H, and M2_72H had 32, 10, and 113 differentially expressed lncRNAs, respectively. Gene ontology (GO) and pathway analyses results showed that melatonin was most beneficial to cashmere growth at 0.2 g/L 72 h, and nuclear factor (NF)-kappaB signaling corresponding to an effect of LncRNA MTC was involved in hair follicle development. We found that melatonin upregulated XLOC_005914 lncRNA (LncRNA MTC). Proliferation increased in the 0.2 g/L 72 h condition and cells with high LncRNA MTC expression, but it was reduced in fibroblasts with knocked down LncRNA MTC expression. This is the first report that LncRNA MTC promotes fibroblast proliferation and regulates hair follicle development and cashmere growth by activating NF-kappaB signaling. PMID- 30291451 TI - Spondyloarthropathy in vertebrae of the aquatic Cretaceous snake Lunaophis aquaticus, and its first recognition in modern snakes. AB - Inflammatory arthritis is documented for the first time in snakes. Ossification of the intervertebral capsule and zygapophyseal joints resulting in segmental vertebral fusion was observed in the aquatic Cretaceous snake Lunaophis aquaticus. Such pathologic alterations are pathognomonic for the spondyloarthropathy form of inflammatory arthritis. A survey of 2144 snakes in recent collections, performed to identify Holocene prevalence, revealed only two occurrences in extant snakes. The findings in Bitis gabonica and Elaphe taeniura were indistinguishable from those noted in Lunaophis aquaticus and identical to those previously recognized in modern varanids. The pathology likely represents a form of reactive arthritis related to enteropathic infection. While the disease probably did not affect general locomotion, its vertebral column position may have compromised mating. PMID- 30291452 TI - Snort acoustic structure codes for positive emotions in horses. AB - While the vocal coding of human and animal internal states has been widely studied, the possible acoustic expression of "positive" emotions remains poorly known. Recent studies suggest that snorts (non-vocal sounds produced by the air expiration through the nostrils) appear to be reliable indicators of positive internal states in several ungulate species. Here, we hypothesised in horses that the acoustic structure of the snort could vary with the subjects' current emotional state. Indeed, a preliminary sound analysis of snorts let us suggest structure variations related to the presence of pulsations. We recorded snorts from 20 horses living in a riding center. Auditory playbacks run with 20 humans first confirmed the existence of two snort subtypes, i.e. one pulsed and one non pulsed. Observations were then conducted to compare the distribution of these two subtypes according to the location (stall/pasture) of the signaller as a contextual determinant of its internal state and to its ears' position as a reflection of its emotional state. We found that both subtypes were preferentially observed in positive contexts, but that pulsed snorts were even more associated with highly appreciated situations (in pasture and with ears forward). This study is a step further in the identification of indicators of positive emotions in horses and more generally in the understanding of the acoustic emotions' coding. PMID- 30291453 TI - Enzymatic determination of uric acid using water-soluble CuInS/ZnS quantum dots as a fluorescent probe. AB - Glutathione-capped water-soluble CuInS/ZnS quantum dots (QDs) were prepared by a microwave-assisted method. Their fluorescence, with excitation/emission peaks at 380/570 nm, is found to be quenched by hydrogen peroxide (H2O2) that is produced by the uricase catalyzed oxidation of uric acid (UA) and oxygen. The findings are used in a quenchometric method for the determination of UA. The effects of different ligands on the QDs, of pH value, buffers, enzyme ratio and reaction time were optimized. The detection limit for UA is 50 nM which is lower than other QD-based method, and the detection ranges extends from 0.25-4.0 MUM. The assay is simple and sensitive, and no further modification of the QDs is required. Graphical abstract ?. PMID- 30291456 TI - Impact of environmental temperatures on mortality, sex and caste ratios in Melipona interrupta Latreille (Hymenoptera, Apidae). AB - Temperature is a major driver of biological phenomena, from metabolism to ecological interactions and rates of evolutionary diversification. However, species vary greatly in their thermal tolerance, as well as the temperature under which they perform best. This study aimed to investigate the effect of experimental manipulation of environmental temperatures on the individual mortality and phenotypic composition of colonies of Melipona interrupta. To fulfill these objectives, 30 colonies in equivalent developmental conditions were artificially subjected to different temperatures. Temperatures were monitored by thermo-hygrometers, and immature mortality and sex and caste ratios were observed in brood combs during 14 months. A strong effect of external temperature on immatures was detected on deviations from 28 to 30 degrees C (the natural average temperature inside the colony), causing an increase in mortality. Likewise, a significant effect of temperature on sex ratio was detected, with male:female ratio decreasing at temperatures below and above 28-30 degrees C. Lastly, there was no clear evidence for an effect of temperature on caste ratio, although queens appeared to become relatively more frequent at warmer temperatures. The results of this study allow us to conclude that anthropogenic changes, whose effect can be extrapolated to the similar natural changes, that modify the environmental temperatures to which M. interrupta colonies are exposed are likely to compromise their survival, mainly through individual mortality. PMID- 30291455 TI - Meta-networks for the study of biogeographical traits in ecological networks: the Mexican hummingbird-plant assemblage. AB - Recent studies on ecological networks have quantified the contribution of ecological, historical, and evolutionary factors on the structure of local communities of interacting species. However, the influence of species' biogeographical traits, such as migratory habits or phylogeographical history, on ecological networks is poorly understood. Meta-networks, i.e., networks that cover large spatial extensions and include species not co-occurring locally, enable us to investigate mechanisms that operate at larger spatial scales such as migratory patterns or phylogeographical distributions, as well as indirect relationships among species through shared partners. Using a meta-network of hummingbird-plant interaction across Mexico, we illustrate the usefulness of this approach by investigating (1) how biogeographical and morphological factors associate with observed interactions and (2) how species-specific biogeographical characteristics associate with species' network roles. Our results show that all studied hummingbird and plant species in the meta-network were interrelated, either directly or through shared partners. The meta-network was structured into modules, resulting from hummingbirds and plants interacting preferentially with subsets of species, which differed in biogeographical, and, to a lesser extent, morphological traits. Furthermore, migrants and hummingbirds from Nearctic, Transition, and widespread regions had a higher topological importance in the meta-network. Our study illustrates how meta-networks may contribute to our current knowledge on species' biogeographical traits and biotic interactions, providing a perspective complementary to local-scale networks. PMID- 30291454 TI - Seasonal changes in eicosanoid metabolism in the brown bear. AB - Polyunsaturated fatty acids (PUFAs) exert several important functions across organ systems. During winter, hibernators divert PUFAs from oxidation, retaining them in their tissues and membranes, to ensure proper body functions at low body temperature. PUFAs are also precursors of eicosanoids with pro- and anti inflammatory properties. This study investigated seasonal changes in eicosanoid metabolism of free-ranging brown bears (Ursus arctos). By using a lipidomic approach, we assessed (1) levels of specific omega-3 and omega-6 fatty acids involved in the eicosanoid cascade and (2) concentrations of eicosanoids in skeletal muscle and blood plasma of winter hibernating and summer active bears. We observed significant seasonal changes in the specific omega-3 and omega-6 precursors. We also found significant seasonal alterations of eicosanoid levels in both tissues. Concentrations of pro-inflammatory eicosanoids, such as thromboxane B2, 5-hydroxyeicosatetraenoic acid (HETE), and 15-HETE and 18-HETE, were significantly lower in muscle and/or plasma of hibernating bears compared to summer-active animals. Further, plasma and muscle levels of 5,6 epoxyeicosatrienoic acid (EET), as well as muscle concentration of 8,9-EET, tended to be lower in bears during winter hibernation vs. summer. We also found lower plasma levels of anti-inflammatory eicosanoids, such as 15dPGJ2 and PGE3, in bears during winter hibernation. Despite of the limited changes in omega-3 and omega-6 precursors, plasma and muscle concentrations of the products of all pathways decreased significantly, or remained unchanged, independent of their pro or anti-inflammatory properties. These findings suggest that hibernation in bears is associated with a depressed state of the eicosanoid cascade. PMID- 30291457 TI - Agriculture Occupational Exposures and Factors Affecting Health Effects. AB - PURPOSE OF REVIEW: Agriculture environments contain a variety of inflammatory aerosols that may increase risk for lung inflammation and disease in exposed individuals. In addition, epidemiological studies have also identified protective effects of rural environments and farming exposures. RECENT FINDINGS: In this review, we will discuss recent literature published since 2016 that investigates the impact of differing agricultural exposures on respiratory health. Discussions include the impact of farming modernization, education, and personal protective equipment usage among workers, timing and duration in mediating lung health outcomes, and population studies investigating the association between exposure and risk for numerous lung diseases. PMID- 30291458 TI - Photoelectrochemical determination of the activity of M.SssI methyltransferase, and a method for inhibitor screening. AB - A photoelectrochemical (PEC) method is described for the determination of the activity of M.SssI methyltransferase (MTase). The assay relies on enzyme-linkage reactions and a DNA intercalator Ru(bpy)2(dppz)2+ (where bpy is 2,2'-bipyridine, and dppz is dipyrido[3,2-a:2',3'-c]phenazine) which both serves as a PEC signal. The PEC electrode was obtained by immobilizing 5'-amino modified DNA strands (containing the methylation recognition site 5'-CCGG-3') on a polyethylenimine (PEI) coated ITO/SnO2 electrode with glutaraldehyde as crosslinking agent. In the presence of MTase and S-adenosyl-L-methionine, the 5'-CCGG-3' sequence in the DNA on the electrode is methylated. This protects the DNA strands from the shear of the methylation-sensitive restriction endonuclease HpaII. Consequently, more intact DNA strands remain on the surface of the electrode, providing more sites for Ru(bpy)2(dppz)2+ binding which in turn results in a high PEC response. The result demonstrates that the photocurrent increases linearly with the activity of MTase from 5 to 80 U.mL-1, and the limit of detection is 0.45 U.mL-1. The other MTases does not enhance the photocurrent, suggesting good selectivity of the assay. The method was also applied to rapid evaluate and screen the inhibitors of MTase. This strategy can be utilized to determinate the activity of other DNA MTases with specific DNA sequence.

PMID- 30291459 TI - A test strip for ochratoxin A based on the use of aptamer-modified fluorescence upconversion nanoparticles. AB - An aptamer-based test strip is described for visual and instrumental determination of the mycotoxin ochratoxin A (OTA). It is based on the use of NaYF4:Yb,Er upconversion nanoparticles (UCNPs) as a label for the aptamer and on the competition between OTA and its complementary sequence for an OTA-specific aptamer. To improve the analytical performance, the optical properties of the UCNPs, the fluidity of the UCNP-aptamer conjugate, and the migration rate on the nitrocellulose membranes were investigated. Under the optimal experimental conditions and by using a 980-nm laser, the relative fluorescence intensity (test line value/control line value) is proportional to the logarithm of the OTA concentration over a range from 5 to 100 ng.mL-1 (R2 = 0.9955). The limit of the detection is 1.86 ng.mL-1. This aptamer based flow assay can be performed within 15 min and has no serious cross-sensitivity to potentially interfering species. It was successfully applied to the determination of OTA in spiked wheat and beer samples. Graphical abstract An aptamer-based upconversion fluorescent strip based on the use of NaYF4:Yb,Er nanoparticles was developed for sensitive detection of Ochratoxin A. The limit of the detection was determined as 1.86 ng.mL-1. The assay can be performed within 15 min, indicating its great potential in point-of care testing. PMID- 30291460 TI - Silicon membrane filter designed by fluid dynamics simulation and near-field stress analysis for selective cell enrichment. AB - Selective cell enrichment technologies can play an important role in both diagnostic and therapeutic areas. However, currently used cell sorting techniques have difficulties in rapidly isolating only the desired target cells from a large volume of body fluids. In this work, we developed a filtering system that can quickly separate and highly concentrate cells from a large volume of solution, depending on their size, using a silicon membrane filter. To overcome the problems caused by material limitations of the brittle silicon, we designed a novel membrane filter with various pore designs. From these designs, the most optimal design with high pore density, while preventing crack formation was derived by applying fluid dynamics simulation and near-field stress analysis. The membrane filter system using the selected design was fabricated, and cell filtration performance was evaluated. The LNCaP cell in horse blood was recovered up to 86% and enriched to 187-fold compared to initial cell populations after filtration at a flow rate of 5 mL/min. The results demonstrate that the filter presented in this study can rapidly and selectively isolate target cells from a large volume of body fluid sample. PMID- 30291461 TI - RANKL-induced c-Src activation contributes to conventional anti-cancer drug resistance and dasatinib overcomes this resistance in RANK-expressing multiple myeloma cells. AB - The survival and growth of multiple myeloma (MM) cells are facilitated by cell cell interactions with bone marrow stromal cells and the bone marrow microenvironment. These interactions induce de novo drug resistance known as cell adhesion-mediated drug resistance. Our previous results recently revealed that the receptor activator of NF-kappaB (RANK) ligand (RANKL), which is expressed by bone marrow stromal cells, contributes to anti-cancer drug resistance through the activation of various signaling molecules and suppression of Bim expression in RANK-expressing MM cells. However, the detailed mechanisms underlying RANKL induced drug resistance remain uncharacterized. In the present study, we investigated the mechanism of RANKL-induced drug resistance in RANK-expressing MM cell lines. We found treatment of MM cells with RANKL-induced c-Src phosphorylation and activation of the downstream signaling molecules Akt, mTOR, STAT3, JNK, and NF-kappaB. In addition, treatment with dasatinib, a c-Src inhibitor, overcame RANKL- and bone marrow stromal cell-induced drug resistance to adriamycin, vincristine, dexamethasone, and melphalan by suppressing c-Src, Akt, mTOR, STAT3, JNK, and NF-kappaB activation and enhancing expression of Bim. Overall, RANKL- and bone marrow stromal cell-induced drug resistance correlated with the activation of c-Src signaling pathways, which caused a decrease in Bim expression. Dasatinib treatment of RANK-expressing MM cells re-sensitized them to anti-cancer drugs. Therefore, inhibition of c-Src may be a new therapeutic approach for overcoming RANKL-induced drug resistance in patients with MM. PMID- 30291462 TI - Identification and fine mapping of Bph33, a new brown planthopper resistance gene in rice (Oryza sativa L.). AB - BACKGROUND: Host-plant resistance is the most desirable and economic way to overcome BPH damage to rice. As single-gene resistance is easily lost due to the evolution of new BPH biotypes, it is urgent to explore and identify new BPH resistance genes. RESULTS: In this study, using F2:3 populations and near isogenic lines (NILs) derived from crosses between two BPH-resistant Sri Lankan rice cultivars (KOLAYAL and POLIYAL) and a BPH-susceptible cultivar 9311, a new resistance gene Bph33 was fine mapped to a 60-kb region ranging 0.91-0.97 Mb on the short arm of chromosome 4 (4S), which was at least 4 Mb distant from those genes/QTLs (Bph12, Bph15, Bph3, Bph20, QBph4 and QBph4.2) reported before. Seven genes were predicted in this region. Based on sequence and expression analyses, a Leucine Rich Repeat (LRR) family gene (LOC_Os04g02520) was identified as the most possible candidate of Bph33. The gene exhibited continuous and stable resistance from seedling stage to tillering stage, showing both antixenosis and antibiosis effects on BPH. CONCLUSION: The results of this study will facilitate map-based cloning and marker-assisted selection of the gene. PMID- 30291464 TI - Photobiomodulation on critical bone defects of rat calvaria: a systematic review. AB - Bone defects following trauma represent a high impact on the quality of life of millions of people around the world. The aim of this study was to review photobiomodulation (PBM) action in the treatment of bone critical defects in rat calvaria, related to evaluation of the current protocols applied. One hundred and forty-seven articles related to the subject were found by searching the main databases (Pubmed, Lilacs, Web of Science, and Scopus) considering the period of publication until the year 2017, and only 14 corresponded the inclusion criteria established for this systematic review. The main parameters of the PBM were expressed in Table 1. In addition, it was possible to observe the use of two different wavelengths (red and infrared), which are considered therapeutic. Most of the evaluated articles presented positive results that describe a greater amount of neoformed bone, an increase in collagen synthesis, and a contribution to microvascular reestablishment. However, two studies report no effect on the repair process when the PBM was used. In addition, we observed considerable variations between the values of power, fluence, and total energy, which make it difficult to compare the results presented between the selected studies. It was possible to conclude that the infrared laser was more effective in positively stimulating the bone repair process of critical defects. Furthermore, a discrepancy was found in the parameter values used, which made it difficult to choose the best protocol for the treatment of this type of lesion. PMID- 30291465 TI - Effectiveness of photopolymerization in composite resins using a novel 445-nm diode laser in comparison to LED and halogen bulb technology. AB - Challenges especially in the minimal invasive restorative treatment of teeth require further developments of composite polymerization techniques. These include, among others, the securing of a complete polymerization with moderate thermal stress for the pulp. The aim of this study is to compare current light curing sources with a blue diode laser regarding curing depth and heat generation during the polymerization process. A diode laser (445 nm), a LED, and a halogen lamp were used for polymerizing composite resins. The curing depth was determined according to the norm ISO 4049. Laser output powers of 0.1, 0.5, 1, and 2 W were chosen. The laser beam diameter was adapted to the glass rod of the LED and the halogen lamp (8 mm). The irradiation time was fixed at 40 s. To ascertain DeltaT values, the surface and ground area temperatures of the cavities were simultaneously determined during the curing via a thermography camera and a thermocouple. The curing depths for the LED (3.3 mm), halogen lamp (3.1 mm) and laser(0.5/1 W) (3/3.3 mm) showed no significant differences (p < 0.05). The values of DeltaTsurface as well as DeltaTground also showed no significant differences among LED, halogen lamp, and laser(1 W). The DeltaTsurface values were 4.1LED, 4.3halogen lamp, and 4.5 degrees C for the laser while the DeltaTground values were 2.7LED, 2.6halogen lamp, and 2.9 degrees C for the laser. The results indicate that the blue diode laser (445 nm) is a feasible alternative for photopolymerization of complex composite resin restorations in dentistry by the use of selected laser parameters. PMID- 30291463 TI - The Multifaceted B Cell Response in Allergen Immunotherapy. AB - While allergen immunotherapy (AIT) for IgE-mediated diseases holds curative potential, the considerable heterogeneity in clinical outcomes may relate to the complex mechanisms of tolerance. The regulation of humoral immunity by AIT contributes to the suppression of allergic responses. Recent findings have revealed novel roles for IgA and IgG antibodies in the induction of tolerance. These mechanisms synergize with their ability to block allergen-IgE binding and mediate inhibitory signaling of effector cells of the allergic response. In addition, the regulatory activity of B cells in AIT extends beyond IL-10 secretion and induction of IgG4. Here, we review the evolution of the B cell response during AIT with special emphasis on the novel protective mechanisms entailing humoral immunity. PMID- 30291466 TI - The downside of antimicrobial agents for wound healing. AB - The use of topical antimicrobials is beneficial for infection control in wound care because wound infection is the major cause of delayed healing. The advantages of topical over systemic antimicrobials include a higher concentration at the target site, fewer systemic adverse effects, and a lower incidence of antimicrobial resistance. Nowadays, topical antimicrobials are divided into three groups: disinfectants, antiseptics, and antibiotics. Only antiseptics and antibiotics can be applied to living skin; therefore, this review will focus only on these groups. The advantages of each topical antimicrobial are well established; however, their disadvantages remain prominent. It is widely known that antiseptics show higher cytotoxicity and a broader spectrum of activity than antibiotics, whereas antibiotics show a higher probability of bacterial resistance development. However, there are still many adverse effects, resulting from each topical antimicrobial. This review aims to summarize the possible adverse effects of commonly used antiseptics (biguanide, silver, iodine, chlorine compounds, and other antiseptics), antibiotics (bacitracin, mafenide, mupirocin, neomycin, and silver sulfadiazine), and natural antimicrobials (curcumin and honey). Moreover, the antimicrobials that should be avoided in particular populations are also summarized in this review in order to increase awareness for antimicrobial selection in those populations. PMID- 30291467 TI - Self-assessment reliability in multiple sclerosis: the role of socio-demographic, clinical, and quality of life aspects. AB - INTRODUCTION: Several multiple sclerosis studies matching self- and physician assessment of disease course and disability show moderate and high agreement respectively. However, the role played by socio-demographic, clinical, and quality of life (QoL) factors was not much investigated. The study aims at exploring how self-/physician agreement could depend on these variables. MATERIALS AND METHODS: Participants were asked to report own disease course and disability according to preset categories. Kappa-value and confidence interval (CI) for disease course and two-way random interclass correlation coefficient (ICC) and CI for disability were calculated to evaluate self-/physician agreement. Chi2 was applied to examine whether other factors (gender, age, education, civil status, disease duration, fatigue, quality of life) had systematic effects. RESULTS: Data analysis on 203 participants indicated fair agreement (Kappa-value = 0.30; 95% CI 0.23-0.38) and no dependency on the categories of each variable for disease course. Satisfactory correlation was found for disability (ICC = 0.74; 95% IC 0.67-0.80), good agreement was found for almost all variable categories, and significant differences were observed for education (better agreement for higher levels), disease duration, fatigue and QoL (better agreement for worse conditions). DISCUSSION: Results seem to suggest that higher education and worse clinical and QoL conditions could engage the patient in developing more disease awareness and realistic self-perception and self evaluation.

AB - The Japan Society of Gynecologic Oncology (JSGO) Guidelines 2017 for the Treatment of Uterine Cervical Cancer are for the purpose of providing standard treatment strategies for cervical cancer, indicating treatment methods currently considered appropriate for cervical cancer, minimizing variances in treatment methods among institutions, improving the safety of treatment and prognosis of diseases, reducing the economic and psychosomatic burden of patients by promoting performance of appropriate treatment, and enhancing mutual understanding between patients and healthcare professionals. The guidelines were prepared through consensus of the JSGO Guideline Committee, based on careful review of evidence gathered through the literature searches and in view of the medical health insurance system and actual clinical practice situations in Japan. The guidelines comprise eight chapters and five algorithms. The main features of the 2017 revision are as follows: (1) evidence was collected using a search formula and with cooperation of the Japan Library Association. The bibliographical search formula was placed at the end of the book; (2) regarding clinical questions (CQs) where evidence or clinical inspection in Japan was lacking, opinions of the Guidelines Committee were described as "proposals for future directions"; (3) cervical intraepithelial neoplasia (CIN) 3 and adenocarcinoma in situ (AIS) were treated as a cervical precancerous lesion; (4) the CQs of endoscopic surgery, radical trachelectomy, and sentinel node biopsy were newly added in Chapter 3, "primary treatment for stage IB-II cervical cancer"; and (5) the CQ about hormone replacement therapy after cancer treatment was newly established. Each recommendation is accompanied by a classification of recommendation categories based on the consensus reached by the Guideline Committee members. Here, we present the English version of the JSGO Guidelines 2017 for the Treatment of Uterine Cervical Cancer.

AB - Venovenous extracorporeal membrane oxygenation (VV-ECMO) is used not only support gas transfer of patients suffering from respiratory failure, but also to manage hypoxic patients with critical airway obstruction during various procedures. We present a case in which we electively used VV-ECMO to facilitate tube placement and tracheal biopsy in a 67-year-old female with critical tracheal stenosis. The patient was transferred to our hospital for a surgical treatment after emergent tracheostomy for postoperative management of cerebral hemorrhage in right putamen. Her trachea was severely stenotic and just enough for a 5.5 mm tracheostomy tube. Removal of tracheostomy tube, tracheal wall biopsy and intra tracheal tube placement were successfully performed under VV-ECMO support, drainage from inferior vena cava returned into the right ventricle (RV). RV perfusion was a very useful and effective method in VV-ECMO system, although some careful wire management was needed under fluoroscopic guidance.

AB - The federal law for higher academic medical professions (MedBG) constitutes a program accreditation as well as a federal licensing exam in medicine; both instruments influence the curricula and their further development.Parallel to the Bologna reform in Switzerland for all university degrees the federal licensing exam in medicine has been revised. The swiss catalogue of learning objectives (SCLO, 2nd edition 2008) served as mandatory content reference for the exam and initiated numerous curricular developments. The new federal licencing exam has been implemented in 2011 comprising a MCQ-Part and a structured clinical practical exam in the OSCE format. Particularly this exam triggered the introduction of OSCEs in Zurich as well as in other Swiss universities.The latest national initiative to increase the number of medical students and the introduction of the new edition of the catalogue of learning objectives in 2017 will have relevant effects on curricular developments in Switzerland. PMID- 30291470 TI - Dickkopf-1 (Dkk-1) serum levels in systemic sclerosis and rheumatoid arthritis patients: correlation with the Trabecular Bone Score (TBS). AB - The aim of this research was to determine any correlations between Dickkopf-1 serum levels (Dkk-1, a natural inhibitor of the Wnt signaling pathway promoting osteoclastogenesis) and the Trabecular Bone Score (TBS), in systemic sclerosis (SSc) and rheumatoid arthritis (RA) patients. It also aimed at determining any difference in Dkk-1 serum levels between SSc and RA patients and a control group (CNT) of healthy subjects. A prospective study was carried out in 60 SSc and 60 RA patients and 60 CNT. Dkk-1 serum levels were evaluated by the ELISA method (Quantikine Human Dkk-1 Immunoassay, R&D System, Minneapolis, USA). The severity of microvascular damage was evaluated by nailfold videocapillaroscopy (NVC patterns: "Early," "Active," "Late"), in the SSc patients. TBS analysis and bone mineral density (BMD, g/cm2) were measured in all patients/subjects. The SSc patients showed higher Dkk-1 serum levels than RA (p < 0.004) and CNT (p < 0.0001) patients. SSc patients, showing the "Late" NVC pattern had statistically higher Dkk-1 serum levels than patients with either the "Active" or "Early" (p < 0.004) patterns. Only in the "Late" NVC pattern group of SSc patients was there a significant negative correlation between Dkk-1 and TBS values (p < 0.0001). The increased Dkk-1 serum levels and decreased TBS values observed suggest a diffuse bone damage in SSc patients with advanced disease, as demonstrated by the concomitant presence of the "Late" NVC pattern. Moreover, the bone remodeling in SSc seems even higher than that in RA patients. PMID- 30291472 TI - Effect of achieved hemoglobin level on renal outcome in non-dialysis chronic kidney disease (CKD) patients receiving epoetin beta pegol: MIRcerA CLinical Evidence on Renal Survival in CKD patients with renal anemia (MIRACLE-CKD Study). AB - BACKGROUND: Previous randomized-controlled trials have shown that targeting higher hemoglobin (Hb) levels using high dose of ESA in non-dialysis chronic kidney disease (NDCKD) patients resulted in poorer cardiovascular outcome; however, it remains unknown how high Hb levels achieved by ESA in clinical practice dose could affect renal outcome. METHODS: In a multicenter prospective observational study, Japanese NDCKD patients with an estimated glomerular filtration rate (eGFR) of >= 6 mL/min/1.73 m2 and renal anemia (Hb < 11 g/dL) treated with epoetin beta pegol (C.E.R.A.) for the first time were divided into two groups by Hb level (< 11 g/dL or >= 11 g/dL) in Week 12 of C.E.R.A. treatment (Week 12 Hb). Renal outcome was defined as time until the first occurrence of one of the following: progression to renal replacement therapy, serum creatinine doubling, or eGFR falling below 6 mL/min/1.73 m2. The effect of Week 12 Hb on the onset of renal events was assessed by the Kaplan-Meier and multivariate Cox regression analyses. RESULTS: In the landmark analysis which included 2851 patients, Kaplan-Meier renal survival rate was 37.57% in the < 11 g/dL group and was significantly higher (51.47%) in the >= 11 g/dL group (P < 0.0001). Multivariate Cox regression analysis revealed significantly higher risk of renal events in the < 11 g/dL group than in the >= 11 g/dL group (hazard ratio: 1.26; 95% confidence interval: 1.05-1.51; P = 0.0103). CONCLUSIONS: The results suggest that week 12 Hb levels >= 11 g/dL achieved with C.E.R.A. treatment were associated with better renal outcomes than Hb levels < 11 g/dL. PMID- 30291473 TI - The urate-lowering efficacy and safety of febuxostat versus allopurinol in Chinese patients with asymptomatic hyperuricemia and with chronic kidney disease stages 3-5. AB - BACKGROUND: While the dose of allopurinol is limited in patients with chronic kidney disease (CKD), information is lacking concerning the efficacy, safety, and maintenance dose of febuxostat in Chinese patients with hyperuricemia and with CKD stages 3-5. METHODS: A single center, prospective cohort study was conducted in patients with CKD stages 3-5 and with hyperuricemia who had not yet begun to undergo renal replacement therapy. We enrolled 208 patients who were newly treated with febuxostat (n = 112) or allopurinol (n = 96) in this study. The efficacy of febuxostat was determined by the proportion of patients with serum uric acid (sUA) < 360 umol/L at the end of the study and changes of renal function. RESULTS: The target of sUA < 360 umol/L was reached by 96.4% of participants in the febuxostat group and 37.5% in the allopurinol group at 6 months. The eGFR in the febuxostat group showed an increase from 28.45 to 30.65 mL/min/1.73 m2 at 6 months, while in the allopurinol group, the eGFR decreased from 28.06 to 24.39 mL/min/1.73 m2. Linear regression analysis showed that the reduction in sUA was significantly associated with an increase in eGFR and decrease in proteinuria. We found that 83.0% of the patients could remain with sUA < 360 umol/L at a maintenance dose of febuxostat 20 mg/day. CONCLUSION: Febuxostat had superior urate-lowering efficacy to that of allopurinol in Chinese Han patients with hyperuricemia with CKD stages 3-5, and the reduction in sUA levels was associated with a slower progression of renal function. PMID- 30291474 TI - Macaca arctoides gammaherpesvirus 1 (strain herpesvirus Macaca arctoides): virus sequence, phylogeny and characterisation of virus-transformed macaque and rabbit cell lines. AB - Herpesvirus Macaca arctoides (HVMA) has the propensity to transform macaque lymphocytes to lymphoblastoid cells (MAL-1). Inoculation of rabbits with cell free virus-containing supernatant resulted in the development of malignant lymphomas and allowed isolation of immortalised HVMA-transformed rabbit lymphocytes (HTRL). In this study, the HVMA genome sequence (approx. 167 kbp), its organisation, and novel aspects of virus latency are presented. Ninety-one open reading frames were identified, of which 86 were non-repetitive. HVMA was identified as a Lymphocryptovirus closely related to Epstein-Barr virus, suggesting the designation as 'Macaca arctoides gammaherpesvirus 1' (MarcGHV-1). In situ lysis gel and Southern blot hybridisation experiments revealed that the MAL-1 cell line contains episomal and linear DNA, whereas episomal DNA is predominantly present in HTRL. Integration of viral DNA into macaque and rabbit host cell genomes was demonstrated by fluorescence in situ hybridisation on chromosomal preparations. Analysis of next-generation sequencing data confirmed this finding. Approximately 400 read pairs represent the overlap between macaque and MarcGHV-1 DNA. Both, MAL-1 cells and HTRL show characteristics of a polyclonal tumour with B- and T-lymphocyte markers. Based on analysis of viral gene expression and immunohistochemistry, the persistence of MarcGHV-1 in MAL-1 cells resemble the latency type III, whereas the expression pattern observed in HTRL was more comparable with latency type II. There was no evidence of the presence of STLV-1 proviral DNA in MAL-1 and HTRL. Due to the similarity to EBV mediated cell transformation, MarcGHV-1 expands the available in vitro models by simian and rabbit cell lines. PMID- 30291475 TI - Biogenic Au@ZnO core-shell nanocomposites kill Staphylococcus aureus without provoking nuclear damage and cytotoxicity in mouse fibroblasts cells under hyperglycemic condition with enhanced wound healing proficiency. AB - The aim of the present study is focused on the synthesis of Au@ZnO core-shell nanocomposites, where zinc oxide is overlaid on biogenic gold nanoparticles obtained from Hibiscus Sabdariffa plant extract. Optical property of nanocomposites is investigated using UV-visible spectroscopy and crystal structure has been determined using X-ray crystallography (XRD) technique. The presence of functional groups on the surface of Au@ZnO core-shell nanocomposites has been observed by Fourier transforms infrared (FTIR) spectroscopy. Electron microscopy studies revealed the morphology of the above core-shell nanocomposites. The synthesized nanocomposite material has shown antimicrobial and anti-biofilm activity against Staphylococcus aureus and Methicillin Resistant Staphylococcus haemolyticus (MRSH). The microbes are notorious cross contaminant and are known to cause infection in open wounds. The possible antimicrobial mechanism of as synthesized nanomaterials has been investigated against Staphylococcus aureus and obtained data suggests that the antimicrobial activity could be due to release of reactive oxygen species (ROS). Present study has revealed that surface varnishing of biosynthesized gold nanoparticles through zinc oxide has improved its antibacterial proficiency against Staphylococcus aureus, whereas reducing its toxic effect towards mouse fibroblast cells under normal and hyperglycaemic condition. Further studies have been performed in mice model to understand the wound healing efficiency of Au@ZnO nanocomposites. The results obtained suggest the possible and effective use of as synthesized core shell nanocomposites in wound healing. PMID- 30291476 TI - Developmental venous anomalies and brainstem cavernous malformations: a proposed physiological mechanism for haemorrhage. AB - The incidental diagnosis of both developmental venous anomalies (DVAs) and cavernous malformations (CMs) in the central nervous system is increasing with improved imaging techniques. While classically silent diseases, these cerebrovascular pathologies can follow an aggressive course, particularly when present in the brainstem. In the last decade, substantial research has focussed on KRIT1-mediated tight junction gene expression and their role in CM development. However, our understanding of the physiologic conditions precipitating symptomatic CM development or CM haemorrhage with and without concomitant DVAs, remains lacking. The only established risk factor for CM haemorrhage is a previous history of haemorrhage, and literature currently reports trauma as the only precipitant for symptomatic events. While plausible, this occurs in a minority, with many patients experiencing occult events. This manuscript presents a hypothesis for symptomatic CM events by first discussing the anatomical pathways for intracranial venous outflow via the internal jugular veins (IJV) and vertebral venous plexus (VVP), then exploring the role of venous flow diversion away from the IJVs under physiologic stress during dynamic postural shift. The resultant increase in intracranial venous pressure can exacerbate normal and pre-existing structural DVA pathologies, with repeated exposure causing symptomatic or CM-inducing events. This pathophysiological model is considered in the context of the role of the autonomic nervous system (ANS) in postural intracranial venous outflow diversion, and how this may increase the risk of DVA or CM events. It is hoped that this hypothesis invokes further investigation into precipitants for DVA or CM events and their sequela and, also, furthers the current knowledge on pathophysiological development of DVAs and CMs. PMID- 30291477 TI - Towards Accurate Segmentation of Retinal Vessels and the Optic Disc in Fundoscopic Images with Generative Adversarial Networks. AB - Automatic segmentation of the retinal vasculature and the optic disc is a crucial task for accurate geometric analysis and reliable automated diagnosis. In recent years, Convolutional Neural Networks (CNN) have shown outstanding performance compared to the conventional approaches in the segmentation tasks. In this paper, we experimentally measure the performance gain for Generative Adversarial Networks (GAN) framework when applied to the segmentation tasks. We show that GAN achieves statistically significant improvement in area under the receiver operating characteristic (AU-ROC) and area under the precision and recall curve (AU-PR) on two public datasets (DRIVE, STARE) by segmenting fine vessels. Also, we found a model that surpassed the current state-of-the-art method by 0.2 - 1.0% in AU-ROC and 0.8 - 1.2% in AU-PR and 0.5 - 0.7% in dice coefficient. In contrast, significant improvements were not observed in the optic disc segmentation task on DRIONS-DB, RIM-ONE (r3) and Drishti-GS datasets in AU-ROC and AU-PR. PMID- 30291478 TI - The Radiologist's Gaze: Mapping Three-Dimensional Visual Search in Computed Tomography of the Abdomen and Pelvis. AB - A radiologist's search pattern can directly influence patient management. A missed finding is a missed opportunity for intervention. Multiple studies have attempted to describe and quantify search patterns but have mainly focused on chest radiographs and chest CTs. Here, we describe and quantify the visual search patterns of 17 radiologists as they scroll through 6 CTs of the abdomen and pelvis. Search pattern tracings varied among individuals and remained relatively consistent per individual between cases. Attendings and trainees had similar eye metric statistics with respect to time to first fixation (TTFF), number of fixations in the region of interest (ROI), fixation duration in ROI, mean saccadic amplitude, or total number of fixations. Attendings had fewer numbers of fixations per second versus trainees (p < 0.001), suggesting efficiency due to expertise. In those cases that were accurately interpreted, TTFF was shorter (p = 0.04), the number of fixations per second and number of fixations in ROI were higher (p = 0.04, p = 0.02, respectively), and fixation duration in ROI was increased (p = 0.02). We subsequently categorized radiologists as "scanners" or "drillers" by both qualitative and quantitative methods and found no differences in accuracy with most radiologists being categorized as "drillers." This study describes visual search patterns of radiologists in interpretation of CTs of the abdomen and pelvis to better approach future endeavors in determining the effects of manipulations such as fatigue, interruptions, and computer-aided detection. PMID- 30291479 TI - Neural networks of aggression: ALE meta-analyses on trait and elicited aggression. AB - There is considerable evidence that emotion dysregulation and self-control impairments lead to escalated aggression in populations with psychiatric disorders. However, convergent quantitative evidence on the neural network explaining how aggression arises is still lacking. To address this gap, peak activations extracted from extant functional magnetic resonance imaging (fMRI) studies were synthesized through coordinate-based meta-analyses. A systematic search in the PubMed database was conducted and 26 fMRI studies met the inclusion criteria. Three separate activation likelihood estimation (ALE) meta-analyses were performed on (1) individual differences in trait aggression (TA) studies, (2) individual differences in TA studies examining executive functioning, and (3) elicited aggression (EA) studies across fMRI behavioral paradigms. Ensuing clusters from ALE meta-analyses were further treated as seeds for follow-up investigations on consensus connectivity networks (CCN) delineated from meta analytic connectivity modeling (MACM) and resting-state functional connectivity (RSFC) to further characterize their physiological functions. Finally, we obtained a data-driven functional characterization of the ensuing clusters and their networks. This approach offers a boarder view of the ensuing clusters using a boarder network perspective. In TA, aberrant brain activations were found only in the right precuneus. Follow-up analyses revealed that the precuneus seed was within the frontal-parietal network (FPN) associated with action inhibition, visuospatial processing and higher-level cognition. With further restricting to only experiments examining executive functioning, convergent evidence was found in the right rolandic operculum (RO), midcingulate cortex (MCC), precentral gyrus (PrG) and precuneus. Follow-up analyses suggested that RO, MCC and PrG may belong to a common cognitive control network, while the MCC seems to be the hub of this network. In EA, we only revealed a convergent region in the left postcentral gyrus. Follow-up CCN analyses and functional characterizations suggested that this region may also belong to the same cognitive control network found in the TA sub-analysis. Our results suggested that escalated aggression arises from abnormal precuneus activities within the FPN, disrupting the recruitment of other large-scale networks such as adaptive cognitive control network. Consequently, failure to recruit such a network results in an inability to generate adaptive responses, increasing the likelihood of acting aggressively. PMID- 30291480 TI - TMS of the occipital face area modulates cross-domain identity priming. AB - Accumulating evidence suggests that besides its function in early facial feature processing, the role of the right occipital face area (rOFA) extends to higher level, image-independent processing. Recent studies hint at the possibility that the activity of this region can be modulated by semantic information as well. To test whether the OFA is sensitive to semantic information in a functionally relevant way, we implemented a cross-domain, name-face priming paradigm combined with state-dependent transcranial magnetic stimulation, whereby stimulation preferentially facilitates the processing of attributes encoded by less active neural populations. Our volunteers performed a familiarity decision task for target face images preceded by primes that were either the name of the same identity (congruent), a name of a different person (incongruent), or the character string 'XXXXX' (no prime). Stimulating the rOFA at target stimulus onset, we observed the disappearance of the behavioral disadvantage of incongruent primes, compared to the vertex control condition. Performance in the congruent and no prime conditions remained intact. This result suggests the existence of neural populations in the rOFA that take part in the semantic processing of identity, probably in interplay with other nodes in the extended face network.

AB - PURPOSE: The commonest surgical procedure for women is cesarean delivery. Postpartum hemorrhage and intra-operative blood during cesarean delivery is a major concern to all obstetricians. This study was conducted to assess the efficacy of the adjuvant use of misoprostol and oxytocin in decreasing intra operative blood loss in cesarean delivery. METHODS: This was a double-blinded randomized clinical trial including 636 term pregnant woman scheduled for cesarean section at Ain Shams University Maternity Hospital, Cairo, Egypt, between February 2013 and February 2014. Participants received either 400-MUg misoprostol rectally or sublingually or placebo before cesarean section together with 5-IU oxytocin IV. The main outcome measure was intra-operative blood loss. Difference between the three groups was analyzed using one-way ANOVA test (for numeric variables) and Chi-square test (for categorical variables). P < 0.05 was considered statistically significant. RESULTS: Intra-operative blood loss was higher in patients who did not receive misoprostol (Placebo Group) (295-1075 ml, 641.7 +/- 135.7) than those who received it, regardless the route of administration, rectal (135-830 ml, 457.5 +/- 140.7; P < 0.001), and sublingual (135-680 ml, 357.8 +/- 129.7; P < 0.001). In addition, sublingual route was associated with significantly lower estimated intra-operative blood loss compared to rectal administration (P < 0.001). CONCLUSIONS: Misoprostol with oxytocin is an effective drug-combination for decreasing intra-operative blood loss during cesarian section with clinical superiority to sublingual over rectal route. PMID- 30291482 TI - Effect of intrauterine injection of human chorionic gonadotropin before fresh embryo transfer on IVF and ICSI outcomes: a meta-analysis. AB - PURPOSE: This analysis was performed to evaluate the effects of intrauterine injection of human chorionic gonadotropin (hCG) before fresh embryo transfer (ET) on the outcomes of in vitro fertilization and intracytoplasmic sperm injection. METHODS: Randomized controlled trials (RCTs) were identified by searching electronic databases. The outcomes of live birth, clinical pregnancy, implantation, biochemical pregnancy, ongoing pregnancy, ectopic pregnancy, and miscarriage between groups with and without hCG injections were analyzed. Summary measures were reported as risk ratios (RR) with 95% confidence intervals. RESULTS: Six RCTs on fresh embryo transfer (ET) were included in the meta analysis. A total of 2759 women undergoing fresh ET were enrolled (hCG group n = 1429; control group n = 1330). Intrauterine injection of hCG significantly increased rates of biochemical pregnancy (RR 1.61) and ongoing pregnancy (RR 1.58) compared to controls. However, there were no significant differences in clinical pregnancy (RR 1.11), implantation (RR 1.17), miscarriage (RR 0.91), ectopic (RR 1.65) or live birth rates (RR 1.13) between the hCG group and control group. CONCLUSION: The current evidence for intrauterine injection of hCG before fresh ET does not support its use in an assisted reproduction cycle. PMID- 30291484 TI - Birthweight thresholds for increased risk for maternal and neonatal morbidity following vaginal delivery: a retrospective study. AB - PURPOSE: To determine neonatal birthweight (BW) thresholds for adverse maternal and neonatal outcome following vaginal delivery. METHODS: A retrospective cohort study of all women with singleton pregnancies who underwent vaginal delivery in a university-affiliated tertiary hospital (1996-2015). The association between BW and adverse outcome in neonates with BW >= 3500 g (> 90th centile BW at 37 weeks' gestation) with 100 g-increment groups was explored. Pregnancies complicated by diabetes mellitus, fetal anomalies or cesarean deliveries were excluded. The composite neonatal outcome was defined as shoulder dystocia or brachial plexus injury. The composite maternal outcome was defined as postpartum hemorrhage or third- or fourth-degree perineal tears. RESULTS: Of the 121,728 deliveries during the study period, 26,920 (22.1%) met inclusion criteria. Of these, 1024 (3.8%) had a composite adverse maternal outcome and 947 (3.5%) had a composite adverse neonatal outcome. The rates of composite maternal outcomes increased significantly only at a BW of 4800 g and above. The composite neonatal outcomes increased significantly only at a BW of 4400 g and above. In multivariate analysis, after subcategorizing our cohort into 3 BW groups [3500-3999 g (control, n = 23,030); 4000-4399 g (n = 3494); >= 4400 g (n = 396)], BW was associated with adverse neonatal outcomes in a dose-dependent manner. In the BW >= 4400 g group, to prevent one case of shoulder dystocia or Erb's palsy, 12 cesarean deliveries needed to be performed. CONCLUSION: For non-diabetic mothers who deliver vaginally, neonatal BW >= 4400 g was associated with a significant increase in adverse neonatal outcomes, whereas neonatal BW >= 4800 g was associated with a significant increase in adverse maternal outcomes. PMID- 30291485 TI - The Molecular Identification and Antifungal Susceptibilities of Aspergillus Species Causing Otomycosis in Tochigi, Japan. AB - Aspergillus species are the most common pathogenic fungi involved in otomycosis, an infection of the outer ear canal. In this study, we examined the incidence of Aspergillus infections and the antifungal susceptibilities of 30 Aspergillus species isolates from patients with otomycosis who visited Saiseikai Utsunomiya Hospital between August 2013 and July 2016. Based on the morphological test results, the strains were identified as Aspergillus niger sensu lato (20 strains), A. terreus sensu lato (7 strains), and A. fumigatus sensu lato (3 strains). In contrast, the molecular identifications based on analyzing the isolates' partial beta-tubulin gene sequences revealed them to be A. niger sensu stricto (12 strains), A. tubingensis (8 strains), A. terreus sensu stricto (7 strains), and A. fumigatus sensu stricto (3 strains). The antifungal susceptibility test results indicated that strains of A. tubingensis and A. niger sensu stricto displayed lower susceptibilities to ravuconazole, compared with the other isolates. The Aspergillus strains from this study showed low minimum inhibitory concentrations toward the azole-based drugs efinaconazole, lanoconazole, and luliconazole. Therefore, these topical therapeutic agents may be effective for the treatment of otomycosis. PMID- 30291486 TI - Familias Unidas for Health and Wellness: Adapting an Evidence-Based Substance Use and Sexual Risk Behavior Intervention for Obesity Prevention in Hispanic Adolescents. AB - We describe the adaptation of Familias Unidas, an evidence-based substance use and sexual risk behavior intervention, for obesity prevention in Hispanic adolescents. Intervention developers and experts in pediatric obesity, exercise physiology, dietetics, and the local parks system provided input for changes. Hispanic families also provided input through a series of 21 focus groups conducted before, during, and after an initial pilot test of the adapted intervention. After transcribing audiotaped sessions, we used a general inductive approach and Dedoose qualitative software to derive themes. Results indicated the need for improved health-related family functioning, enhanced nutrition education and skill building, increased family engagement in physical activity, and stronger links between family and environmental supports. Parents who participated in the pilot test expressed high enthusiasm for hands-on nutrition training and reported improvements in family functioning. Adolescents liked outdoor physical activities but wanted parents to be more engaged in joint physical activity sessions. The adapted intervention maintains fidelity to Familias Unidas' core theoretical elements and overall structure, but also includes content focused on physical activity and nutrition, adolescent participation in physical activity sessions led by park coaches, and joint parent adolescent participation in physical activity and nutrition skill-building activities. PMID- 30291487 TI - Study of kinetics of 19F-MRI using a fluorinated imaging agent (19FIT) on a 3T clinical MRI system. AB - PURPOSE: To use 19F imaging tracer (19FIT-27) to evaluate kinetics in major organs. INTRODUCTION: Kinetics studies using proton MRI are difficult because of low concentration of 19FIT-27 protons relative to background water protons. Because there is no background source of 19F NMR in a biological body, 19F may be an ideal nucleus to directly trace 19FIT-27. However, there are several challenges for reliable 19F MR imaging and spectroscopy, particularly with clinical whole-body MRI systems, which include low concentrations and long 19F T1. METHODS AND MATERIALS: We performed a dynamic 19F MRI study on mice at a 3T whole-body MRI system using a homemade transmit/receive (Tx/Rx) switch and a Tx/Rx volume RF coil. We used a newly developed fluorine imaging agent, which has 27 identical fluorine atoms with identical chemical shift, a relatively short T1, and high hydrophilicity. Basic kinetics parameters were estimated from the 19F signal-time curve. RESULTS AND DISCUSSIONS: Resultant fluorine images show fairly high spatial (3 * 3 * 3 mm3) and temporal resolutions. Biodistribution and kinetics of 19FIT-27 are obtained via 19F images for major uptake organs. CONCLUSIONS: Whole-body dynamic 19F MRI of newly developed 19FIT-27 in mice was obtained with fairly high spatial and temporal resolutions on a 3T clinical MRI system. The present study demonstrates the feasibility of 19F MRI using our newly developed compound to investigate major organ kinetics. PMID- 30291488 TI - Association between clusterin concentration and dementia: a systematic review and meta-analysis. AB - Studies have showed that high clusterin (CLU) concentration was associated with increased risk of dementia. However, the results based on small samples remained controversial. The aim of our study was to determine the relationship between CLU concentration and the late-life cognitive outcomes including mild cognitive impairment (MCI), Alzheimer's disease (AD), vascular dementia (VAD), Parkinson's disease related dementia (PDD), Lewy body dementia (DLB) and frontotemporal dementia (FTD). A comprehensive search was conducted to screen the eligible studies in online database PubMed, Web of Science and Embase from 1950 to January 2017 according to the preferred reporting items for systematic reviews and meta analyses (PRISMA) checklist. The CLU concentration data in brain tissue, cerebrospinal fluid (CSF), serum and plasma was collected to determine the strength of this association. The results were presented with standard difference of the mean (SDM) with 95% confidence intervals (CIs). A total of 28 studies were identified to calculate the association between CLU concentration and dementia. The results showed that the CLU concentration in the plasma (SDM = 0.73, 95% CI 0.26-1.19, P = 0.002) and brain tissue (SDM = 0.71, 95% CI 0.10-1.32, P = 0.022) was increased in dementia compared to normal control. Subgroup analysis showed that the plasma CLU concentration was significantly increased only in the AD group (SDM = 1.85, 95% CI 0.84-2.85, P < 0.001), but not in MCI or other dementias. No association was found between serum and CSF clusterin concentration and dementia. This meta-analysis indicates that high CLU concentration in the plasma and brain is associated with dementia, especially in AD. PMID- 30291489 TI - Rescue Nuss procedure for inferior vena cava compression syndrome following posterior scoliosis surgery in Marfan syndrome. AB - PURPOSE: Scoliosis surgery in Marfan syndrome is common, even in the presence of a funnel chest. However, to date, no case has been reported with acute intra /postoperative decompensation caused by vena cava compression following posterior spinal derotation and fusion. METHODS: A 15-year-old male patient with Marfan syndrome, a funnel chest and severe scoliosis was treated with surgery for the spinal deformity. Intraoperatively, the patient developed a clinically relevant compression of the inferior vena cava with severe circular depression. Postoperatively, a cava compression syndrome with severe pleural effusion, ascites and enormous swelling of the lower limbs was developed. A conservative treatment of the symptoms, consisting of thoracic drainage and negative fluid balance, failed. Subsequently, the patient was transferred to pediatric intensive care unit for further treatment. Echocardiography and a CT scan demonstrated cava compression syndrome. A rescue Nuss procedure of the funnel chest deformity was performed since conservative treatment failed. The clinical course proceeded without complications and with a decrease in clinical symptoms of inferior inflow congestion. The patient was discharged after almost 3 weeks. CONCLUSION: The problem of congenital stenosis of the inferior vena cava in Marfan syndrome has not yet been investigated. In the case of simultaneously existing funnel chest and scoliosis in Marfan syndrome, an interdisciplinary discussion is required to decide whether a repair of the funnel chest should be performed first in order to prevent a clinically relevant compression syndrome. For the detection of a preoperatively relevant stenosis of the inferior vena cava, an MRI or thoracic/abdominal CT should be used preoperatively. PMID- 30291491 TI - Avidekel Cannabis extracts and cannabidiol are as efficient as Copaxone in suppressing EAE in SJL/J mice. AB - Multiple sclerosis (MS) is an autoimmune disease leading to the destruction of myelin with consequent axonal degeneration and severe physical debilitation. The disease can be treated with immunosuppressive drugs that alleviate the symptoms and retard disease aggravation. One such drug in clinical use is glatiramer acetate (Copaxone). The non-psychotropic immunosuppressive cannabinoid compound cannabidiol (CBD) has recently been shown to have beneficial effects on experimental autoimmune encephalomyelitis (EAE). The aim of our study was to compare the efficacy of CBD and standardized extracts from a CBD-rich, ?9-THClow Cannabis indica subspecies (Avidekel) with that of Copaxone. Our data show that CBD and purified Avidekel extracts are as efficient as Copaxone to alleviate the symptoms of proteolipid protein (PLP)-induced EAE in SJL/J mice. No synergistic effect was observed by combining CBD or Avidekel extracts with Copaxone. Our data support the use of Avidekel extracts in the treatment of MS symptoms. PMID- 30291490 TI - Immunomodulatory properties of captopril, an ACE inhibitor, on LPS-induced lung inflammation and fibrosis as well as oxidative stress. AB - BACKGROUND: The role of angiotensin converting enzyme inhibitors on the inflammation process has been demonstrated previously. In the present study, the effects of captopril on lung injury induced by lipopolysaccharide (LPS) were investigated. METHODS: Control, LPS, 12.5, 25 and 50 mg/kg captopril-treated before LPS administration and captopril 50 mg/kg before saline administration groups of rats were studied. Total and percentage of differential WBC, the levels of MDA, total thiol groups, the activities of SOD and CAT, the levels of IFN gamma, PGE2, TGF-beta1 and IL-4 in the BALF were evaluated. RESULTS: MDA concentration in LPS groups treated with all captopril concentrations, total WBC in LPS + Cap50, percent of neutrophils in LPS + Cap25 and LPS + Cap50, levels of IFN-gamma, PGE2, TGF-beta1 in LPS + Cap50 and IFN-gamma/IL-4 ratio in LPS + Cap25 and LPS + Cap50 were significantly decreased but total thiol groups and activity of SOD in LPS + Cap25 and LPS + Cap50, percent of lymphocyte, CAT activity and concentration of IL-4 only in LPS + Cap50 group were increased in comparison to the LPS group (p < 0.05 to p < 0.001). CONCLUSION: Captopril dose dependently improved oxidant-antioxidant biomarkers, the imbalance between pro-inflammatory and anti-inflammatory cytokines and showed specific immunomodulatory effect on Th1/Th2 balance in the BALF of lung injury induced by LPS. PMID- 30291492 TI - Neuronal Responses of Antennal Olfactory Sensilla to Insect Chemical Repellents in the Yellow Fever Mosquito, Aedes aegypti. AB - The yellow fever mosquito, Aedes aegypti, is a vector of many human diseases such as yellow fever, dengue fever, and Zika. As insecticide resistance has been widely reported, chemical repellents have been adopted as alternative options for mosquito and mosquito-borne disease control. This study characterized the responses of olfactory receptor neurons (ORNs) in different types of antennal olfactory sensilla in Ae. aegypti to 48 chemicals that exhibited repellent activity in various insect species. Both excitatory and inhibitory responses were observed from ORNs in response to these chemicals and differential tuning properties were also observed among ORNs. Remarkable excitatory responses were recorded from the ORNs in sensilla SST1, SST2, SBTI, SBTII, and LST2, while inhibitory activities were detected from a neuron in sensillum SST2 in response to several terpene/terpenoid compounds. Moreover, the temporal dynamics of neuronal responses were found to be compound-specific and concentration dependent. Hierarchical cluster analysis and principal component analysis of the response to each compound across ORNs in seven types of olfactory sensilla in Ae. aegypti revealed that odor reception depended not only on chemical class but also specific chemical structure. Results of this study give new insights into the sensory physiology of Aedes mosquitoes to the chemical repellents and should contribute to the development of new repellent reagents for human protection. PMID- 30291493 TI - Characteristics, treatment and outcome of bleeding after tooth extraction in patients on DOAC and phenprocoumon compared to non-anticoagulated patients-a retrospective study of emergency department consultations. AB - OBJECTIVES: Bleeding after tooth extraction range from minor bleeding to life threating haemorrhagic shock and are among the leading complications in patients under oral anticoagulation with direct oral anticoagulants (DOACs) or phenprocoumon. Little is known about how anticoagulation in patients under DOAC or phenprocoumon alters the characteristics, treatment or outcome of bleeding events, in comparison to non-anticoagulated patients. METHODS: Patients admitted to a tertiary ED in Bern, Switzerland, from June 1st 2012 to 31st May 2016 with bleeding related to tooth extraction under DOAC, phenprocoumon or without anticoagulation, were compared. RESULTS: Out of 161,458 emergency consultations, 64 patients with bleeding from tooth extraction were included in our study. In anticoagulation groups, we found significantly more delayed bleeding events than in patients without anticoagulation (9 (81.3%) DOAC, 19 (86.4%) phenprocoumon, 8 (30.8%) no anticoagulation, p < 0.001). Anticoagulated patients had to stay longer in the ED than non-anticoagulated patients, with no significant difference between DOAC or phenprocoumon (hours: 4.8 (3.2-7.6 IQR) DOAC, 3.0 (2.0-5.5 IQR) phenprocoumon, p = 0.133; 2.7 (1.6-4.6) no anticoagulation; p = 0.039). More patients with anticoagulation therapy needed surgery than patients without anticoagulant therapy (11 (68.8%) DOAC, 12 (54.6%) VKA, p = 0.506; 7(26.9%) no anticoagulation; p = 0.020). CONCLUSIONS: Delayed bleeding occur more often in anticoagulated patients with both DOAC and phenprocoumon compared to patients without anticoagulation. Bleeding events in anticoagulated patients with DOAC and phenprocoumon equally need longer ED treatment and more frequent surgical intervention. CLINICAL RELEVANCE: Caution with delayed bleeding in anticoagulated patients with DOACs and phenprocoumon is necessary and treatment of bleeding is resource-demanding. PMID- 30291494 TI - Effect of intermittent teriparatide (PTH 1-34) on the alveolar healing process in orchiectomized rats. AB - OBJECTIVE: To evaluate intermittent teriparatide therapy's influence on the alveolar healing process in rats with induced osteoporosis. MATERIALS AND METHODS: Fifty-four male rats were divided into three groups: fictitious surgery (SHAM), bilateral orchiectomy (ORQ NT), and bilateral orchiectomy treated with teriparatide (ORQ TERI). Right upper incisor extraction was performed. After 14 and 42 days, the rats were euthanized. Immunolabeling analysis was performed in order to characterize bone turnover through Wnt, alcaline phosphatase, osteocalcin, and TRAP presence in tissue; micro-CT analysis was performed in order to determine the bone volume fraction (BV/TV), trabecular thickness, separation, and number (Tb.Th, Tb.Sp, Tb.N). For the micro-CT data, statistical analysis was performed through one-way ANOVA and Tukey post-test, for parametrical data, with significance level adopted in p < 0.05. Days, Wnt, alkaline phosphatase, and osteocalcin revealed more labeling for ORQ TERI and less for TRAP. For the Tb.N in the ORQ NT group was 0.496 mm, a significant statistical difference was observed between the groups of ORQ NT and ORQ TERI (p < 0.05). For the BV/TV, Tb.Sp, and Tb.Th parameters, no significant statistical difference was observed among the three experimental groups (p > 0.05). CONCLUSIONS: Treatment with intermittent teriparatide reverted impairment in the metabolism of repairing bone tissue in orchiectomized animals. CLINICAL RELEVANCE: Cases of decreased bone density such as osteoporosis can lead to delayed alveolar repair process. PTH 1-34 has been shown to be a medication that improves this repair, making bone of low quality into one with normal features. PMID- 30291495 TI - Prevention of oral carcinogenesis in rats by Dracaena cinnabari resin extracts. AB - OBJECTIVES: In vivo study was performed to determine the chemopreventive efficacy of the DC resin methanol extract on a 4-nitroquinoline-1-oxide (4NQO) oral cancer animal model. MATERIALS AND METHODS: This study involves administration of 4NQO solution for 8 weeks alone (cancer induction) or with Dracaena cinnabari (DC) extract at 100, 500, and 1000 mg/kg. DC extract administration started 1 week before exposure until 1 week after the carcinogen exposure was stopped. All rats were sacrificed after 22 weeks, and histological analysis was performed to assess any incidence of pathological changes. Immunohistochemical expressions of selected tumor marker antibodies were analyzed using an image analyzer computer system, and the expression of selected genes involved in apoptosis and proliferative mechanism related to oral cancer were evaluated using RT2-PCR. RESULTS: The incidence of OSCC decreased with the administration of DC extract at 100, 500, and 1000 mg/kg compared to the induced cancer group. The developed tumor was also observed to be smaller when compared to the induced cancer group. The DC 1000 mg/kg group inhibits the expression of Cyclin D1, Ki-67, Bcl-2, and p53 proteins. It was observed that DC 1000 mg/kg induced apoptosis by upregulation of Bax and Casp3 genes and downregulation of Tp53, Bcl-2, Cox-2, Cyclin D1, and EGFR genes when compared to the induced cancer group. CONCLUSIONS: The data indicated that systemic administration of the DC resin methanol extract has anticarcinogenic potency on oral carcinogenesis. CLINICAL RELEVANCE: Chemoprevention with DC resin methanol extract may significantly reduce morbidity and possibly mortality from OSCC. PMID- 30291496 TI - Effects of replacing rice bran with tamarind seed meal in concentrate mixture diets on the changes in ruminal ecology and feed utilization of dairy steers. AB - Feed ingredients costs have been impacting the production cost. Attempts have been made to use local feed resources in order to reduce feed costs. The objective of this study was to identify effect of using crushed tamarind seed meal (TSM) in concentrate mixture on rumen fermentation, dry matter intake, and digestibility of dairy steers. Four rumen-fistulated dairy steers were used in a 4 * 4 Latin Square Design. Four levels of TSM were used to replace rice bran (RB) in the concentrate mixtures in four treatments (T1 = 0% replacement of RB, T2 = 30% replacement of RB, T3 = 60% replacement of RB, T4 = 100% replacement of RB). The findings revealed that replacement of TSM for RB resulted in similar digestibility of nutrients and intakes (P > 0.05). However, rumen fermentation parameters were remarkably improved, namely total VFA and the concentration of C3 especially at the highest level of replacements (100%, T4), (P < 0.05). Rumen protozoal population was found lowered in all replacements, especially those in higher levels of TSM replacement. Consequently, the rumen methane productions were significantly reduced. TSM can be a promising energy source to replace rice bran, hence lowering the cost of concentrate mixture. PMID- 30291497 TI - Stability of Autistic Traits from 5 to 8 Years of Age Among Children in the General Population. AB - Little is known about the across time stability of autistic traits during the transition period from preschool to school age in the general population. The current study compared autistic traits assessed by a mother-reported quantitative measure, the Social Responsiveness Scale, at age 5 and 8 years and examined the intraclass correlation coefficients of scores across the period for 168 Japanese community-based children. Results showed that total and two subdomain-related autistic trait scores remained primarily stable in males and females. This stability was observed for both children with higher and lower autistic traits scores with a possible sex-specific pattern. Our findings suggest that autistic traits in the general population can be reliably assessed using quantitative measures for this age period. PMID- 30291498 TI - Dissecting Tissue-Specific Super-Enhancers by Integrating Genome-Wide Analyses and CRISPR/Cas9 Genome Editing. AB - Recent advances in genome-wide sequencing technologies have provided researchers with unprecedented opportunities to discover the genomic structures of gene regulatory units in living organisms. In particular, the integration of ChIP-seq, RNA-seq, and DNase-seq techniques has facilitated the mapping of a new class of regulatory elements. These elements, called super-enhancers, can regulate cell type-specific gene sets and even fine-tune gene expression regulation in response to external stimuli, and have become a hot topic in genome biology. However, there is scant genetic evidence demonstrating their unique biological relevance and the mechanisms underlying these biological functions. In this review, we describe a robust genome-wide strategy for mapping cell-type-specific enhancers or super-enhancers in the mammary genome. In this strategy, genome-wide screening of active enhancer clusters that are co-occupied by mammary-enriched transcription factors, co-factors, and active enhancer marks is used to identify bona fide mammary tissue-specific super-enhancers. The in vivo function of these super-enhancers and their associated regulatory elements may then be investigated in various ways using the advanced CRISPR/Cas9 genome-editing technology. Based on our experience targeting various mammary genomic sites using CRISPR/Cas9 in mice, we comprehensively discuss the molecular consequences of the different targeting methods, such as the number of gRNAs and the dependence on their simultaneous or sequential injections. We also mention the considerations that are essential for obtaining accurate results and shed light on recent progress that has been made in developing modified CRISPR/Cas9 genome-editing techniques. In the future, the coupling of advanced genome-wide sequencing and genome-editing technologies could provide new insights into the complex genetic regulatory networks involved in mammary-gland development. PMID- 30291499 TI - The dramatic essence of the narrative approach. AB - Even though it is not a methodology on the level of principlism or casuistry, narrative bioethics nonetheless contributes to and guides decision-making in the field of biomedical ethics. However, unlike other methodologies, the narrative approach lacks a set of specific patterns and formal rules for doing so. This deficiency leaves this approach more vulnerable to the influence of historical factors; in fact, the vital history of a person is made up of thousands of scenes, which one must select and group under different norms. Yet the historicity of narrative does not destroy its normative value; rather, it gives rise to a confluence of stories that contradict one another on the basis of their practical consequences. This problem is less severe in traditional cultures, where some stories take precedence over others according to the normative value conferred through the supposed authority of their sources. But it manifests in an intense manner within current multicultural societies. It is imperative to find the thread that leads outside the labyrinth of subjectivity. This paper shows that the end of this thread lies, paradoxically, not in actions but in the subject-actors that perform them-specifically when such subjects are conceived as dramaturgical characters in narrative. PMID- 30291500 TI - "Tupanvirus", a new genus in the family Mimiviridae. AB - The genus "Tupanvirus" is a new proposed taxon to be included in the family Mimiviridae. The two known tupanvirus isolates were isolated from soda lake and oceanic sediments samples collected in Brazil and were named "tupanvirus soda lake" and "tupanvirus deep ocean", respectively. These viruses exhibit similarities to amoeba-infecting mimiviruses, but there are also several differences that place them in a separate group within the family Mimiviridae. Their virions have a mean size of 1.2 um, which include a mimivirus-like capsid and a large cylindrical tail, both covered by fibrils. The linear double-stranded DNA genomes of up to 1,516,267 base pairs encode over 1,200 genes, among which ~ 30% have no homologs in any database, including in other mimivirus genomes. Compared to other mimiviruses, tupanviruses exhibit a broader host range and cause a cytotoxic effect in host and non-host organisms, a phenotype that is not observed for other mimiviruses. Remarkably, these viruses possess the most complete gene set related to the protein synthesis process, including 20 aminoacyl-tRNA synthetases, 67-70 tRNAs, many translation factors, and genes involved in maturation and modification of tRNA and mRNA, among others. Moreover, diverse phylogenomic analyses put tupanviruses in a distinct group within the family Mimiviridae. In light of the set of different features observed for these giant viruses, we propose establishment of a new genus to allow proper classification of two known tupanviruses and possibly many more similar viruses yet to be characterized. PMID- 30291501 TI - Genetic characterization of a novel unique recombinant form of HIV-1 originating from subtype A1 and C in Guangdong Province, China. AB - The dominant human immunodeficiency virus type 1 (HIV-1) subtypes are CRF01_AE, CRF07_BC and CRF08_BC in Guangdong Province, China. In this study, we report a unique recombinant form (URF) of HIV-1 that was identified in an HIV/hepatitis B virus (HBV)/hepatitis C virus (HCV) triple-infected patient who was an intravenous drug user (IDU) in Heyuan City, Guangdong Province. The near full length genome was amplified, and the PCR products were sequenced by Sanger's method. The Recombination Identification Program (RIP 3.0) and jpHMM online tools showed that four subtype C fragments were inserted into the A1 backbone genome in the gag, pol, vpr and nef gene regions. In the phylogenetic tree analysis, the subtype A1 and C fragments clustered with HIV-1 A1 and C reference sequences, respectively. No similar breakpoints between our strain and the other strains in the Los Alamos HIV database were observed. The results of evolutionary analysis using BEAST software showed that the subtype A1 fragment originated from Guangzhou City, China; however, the subtype C fragment originated from East Africa. This is the first report of HIV-1 URF A1C in Guangdong Province, China. The identification of this URF suggested that further dynamic surveillance of new recombinant forms is needed. PMID- 30291502 TI - Evidence of avian poxvirus and papillomavirus infection in Gyps fulvus in Italy. AB - The identification of avian poxvirus and avian papillomavirus associated with cutaneous lesions in griffon vultures (Gyps fulvus) by histopathology, electron microscopy and PCR analysis is reported. Sequence analysis of the fpv140 gene revealed 99% identity to two poxviruses obtained from a white-tailed sea eagle (Haliaeetus albicilla) and a common buzzard (Buteo buteo). Partial sequence of the papillomavirus L1 gene showed sequence similarity to papillomavirus LI genes from African grey parrot (Psittacus erithacus) (69% identity), duck (Anas platyrhynchos) (68% identity), and yellow-necked francolin (Francolinus leucoscepus) (66% identity). To date, this is the first identification of avian poxvirus and papillomavirus in griffon vultures and the first evidence of infection of both viruses in live wild birds. PMID- 30291503 TI - Development and comparison of two H5N8 influenza A vaccine candidate strains. AB - Avian influenza viruses circulating in birds have caused outbreaks of infection in poultry and humans, thereby threatening public health. Recently, a highly pathogenic avian influenza (HPAI) virus (H5N8) of clade 2.3.4.4 emerged in Korea and other countries and caused multiple outbreaks in domestic and wild birds, with concerns for human infection. To combat HPAI viral infections, novel vaccines are likely to be the most effective approach. Therefore, in this study, we generated H5N8 vaccine candidate viruses based on a Korean isolate (A/broiler duck/Korea/Buan2/2014). The vaccine candidate viruses were 2:6 reassortants expressing the two surface glycoproteins of A/broiler duck/Korea/Buan2/2014 on an A/Puerto Rico/8/34 (PR8) backbone generated by using an eight-plasmid-based reverse genetics system with or without replacement of the multi-basic amino acid cleavage motif (MBCM, a crucial pathogenic factor in HPAI virus) with a bi-basic amino acid cleavage motif (BBCM) in their HA. An H5N8 vaccine candidate virus containing the BBCM showed attenuated pathogenesis in embryonated eggs and exhibited less virulence in the infected mice compared with the wild H5N8 virus containing an MBCM. Vaccination with an inactivated preparation of the vaccine candidate virus protected mice from lethal H5N8 viral challenge. This is the first report of the development and evaluation of H5N8 vaccine strains (with an MBCM or BBCM) of HA clade 2.3.4.4 as vaccine candidates. Our findings suggest that H5N8 strains with a BBCM instead of an MBCM might be considered for H5N8 vaccine seed virus development or as a reference vaccine against H5N8 viral strains. PMID- 30291504 TI - Crude extracts of recombinant baculovirus expressing rabbit hemorrhagic disease virus 2 VLPs from both insect and rabbit cells protect rabbits from rabbit hemorrhagic disease caused by RHDV2. AB - Vaccines against viral pathogens are often composed of recombinant proteins expressed in different systems. Such proteins expressed by recombinant baculoviruses have been proven to be effective for vaccination. Especially, after codon usage optimization high amounts of recombinant viral proteins can be obtained which can assemble to virus like particles (VLPs) spontaneously. In this study we compared two different codon usages of RHDV2-VP1 to improve the expression of recombinant VP1 of RHDV2 by recombinant baculoviruses after infection of insect SF9 cells or transduction of mammalian RK13 cells in order to gain high protein yields. Also the influence on the auto-assembly of RHDV2-VP1 to VLPs was investigated. Finally, the immunogenic potential of such recombinant vaccines against RHDV2 to induce a protective immune response in rabbits against RHDV2 should be characterized. There was no influence of different codon usages on RHDV2-VP1 gene expression in the respective cell lines detected. However, in insect cell line SF9 higher rates of recombinant VP1 were measured in comparison to the transduction of mammalian cells RK13. Auto-assembly of RHDV2-VP1 to VLPs was observed in both cell systems by electron microscopy. Finally, both RHDV-VP1 VLPs derived from mammalian and insect cells were able to induce a protective humoral immune response in rabbits against RHDV2. PMID- 30291505 TI - Phenotypic assortment by body shape in wild-caught fish shoals. AB - Phenotypic variation plays a critical role in determining the structural organisation and ecological function of wild populations. Animal groups are often structured according to factors such as species, sex, body size and parasite load, but it is unclear whether body shape also influences patterns of social organisation, and thus contributes to population phenotypic structure. Here, we use geometric morphometric analyses to determine whether wild-caught shoals of a freshwater fish, the western rainbowfish (Melanotaenia australis), are structured according to body size and shape. Using randomisation analyses, we show that the level of variation in size and shape observed in natural group assemblages is lower than that expected under a null model of random shoal composition. In addition, we found evidence of further phenotypic structuring along an upstream downstream environmental gradient. The putative benefits of morphological assortment include a reduction in predation risk (due to prey oddity and predator confusion effects) and increased hydrodynamic or foraging efficiency. We suggest that morphological variation is a neglected component of population social organisation that can affect population processes, such as patterns of gene flow, and ecological interactions, such as predator-prey dynamics. PMID- 30291506 TI - Multi-criteria Mapping of Stakeholders' Viewpoints in Five Southeast Asian Countries on Strategies to Reduce Micronutrient Deficiencies Among Children and Women of Reproductive Age: Findings from the SMILING Project. AB - BACKGROUND: Despite scientific evidence on the potential impact or importance of specific interventions to improve micronutrient status of vulnerable groups, political commitment and extensive support from national stakeholders is paramount to support introduction and implementation of these interventions at national level. In order to develop efficient nutritional strategies to improve the micronutrient status of children < 5 years of age and women of reproductive age that will be supported by a wide range of stakeholders, a better understanding of viewpoints on the nutrition politics and strategies is necessary. Multi-criteria mapping (MCM) was successfully used to assess the stakeholder's viewpoint in a wide variety of contexts since the late 1990s. OBJECTIVE: The objective of the present study was to assess the viewpoints of stakeholders on a wide range of potential nutritional interventions in the five Southeast Asian countries participating in the SMILING project. METHOD: MCM methodology was used to appraise the stakeholder's viewpoints in five countries. RESULTS: The results show that the overall stakeholders' preference was for actions already implemented in their country rather than for new, innovative options, even for supplementation. Indirect interventions such like food fortification (except in Indonesia), delayed cord clamping or food-based approaches were generally less favored by the stakeholders. However, the majority of stakeholders agreed that new approaches should be considered and put in place in the future provided that evidence of their impact was demonstrated, that they received adequate technical support for their implementation and their monitoring, and that they will be accompanied by strong advocacy among decision makers, civil society and beneficiaries. CONCLUSIONS FOR PRACTICE: To conclude, for the introduction of new, innovative strategies to reduce micronutrient deficiencies in South-East Asia, convincing stakeholders appears to be the first hurdle to be taken. PMID- 30291508 TI - Nimura lecture: why are you evaluating RV function in patients with pulmonary arterial hypertension? AB - LV is a pressure-generating pump which endures pressure overload, while RV is a flow-generating pump intolerant of pressure overload. Therefore, RV pump function (but not RV myocardial contractility) can easily fail in face of severe pulmonary arterial hypertension (PH) because of increased afterload. Available indexes of RV function are load dependent and incapable of accurately reflecting RV myocardial contractility. Animal RV in which myocardium is damaged extensively by either soldering iron or coronary occlusion can work well without causing systemic congestion or decreased SV. In clinical settings, evaluation of pre treatment RV function in patients with PH has limited value in predicting prognosis. Furthermore, in virtually all patients with PH after successful lung transplantation, RV function has been reported to improve indicating that deteriorated RV function in patients with PH is due to an increase in RV afterload, but not to decreased RV myocardial contractility. In view of these facts, evaluation of RV function seems hardly useful in patients with PH. PMID- 30291509 TI - Changes in dynamic mitral valve geometry during percutaneous edge-edge mitral valve repair with the MitraClip system. AB - BACKGROUND: The aim of this study was to quantify the acute dynamic changes of mitral valve (MV) geometry throughout the cardiac cycle-during percutaneous MV repair with the MitraClip system by 3-dimensional transesophageal echocardiography (3D TEE). METHODS: The MV was imaged throughout the cardiac cycle (CC) before and after the MitraClip procedure using 3D TEE in 28 patients (mean age, 77 +/- 8 years) with functional mitral regurgitation (FMR). Dynamic changes in the MV annulus geometry and anatomical MV orifice area (AMVOA) were quantified using a novel semi-automated software. RESULTS: Percutaneous MV repair decreased anterior-posterior diameter by up to 9% (at 50% of CC; from 34.5 to 31.9 mm; p < 0.001) throughout the CC and increased the diastolic lateral-medial diameter by up to 7% (at 60% of the CC; from 39.7 to 42.3 mm; p < 0.001), whereas the annular circumference and area were not significantly affected. Annulus sphericity index was reduced up to 13% (at 50% of the CC; from 0.89 to 0.78, p < 0.001). The AMVOA also decreased during systole, the maximum decrease being from 0.6 to 0.2 mm2 (at 0% of CC; p = 0.007), and during diastole the maximum decrease being from 4.6 to 1.6 cm2 (at 50% of CC; p < 0.001). CONCLUSIONS: Percutaneous MV repair reduces the MR by an improved coaptation of MV leaflets joint with a simultaneous indirect reduction of anterior-posterior diameter. Further, the MitraClip procedure leads to a reduction of AMVOA of more than 60% during diastole. PMID- 30291507 TI - Evolution of protein transport to the chloroplast envelope membranes. AB - Chloroplasts are descendants of an ancient endosymbiotic cyanobacterium that lived inside a eukaryotic cell. They inherited the prokaryotic double membrane envelope from cyanobacteria. This envelope contains prokaryotic protein sorting machineries including a Sec translocase and relatives of the central component of the bacterial outer membrane beta-barrel assembly module. As the endosymbiont was integrated with the rest of the cell, the synthesis of most of its proteins shifted from the stroma to the host cytosol. This included nearly all the envelope proteins identified so far. Consequently, the overall biogenesis of the chloroplast envelope must be distinct from cyanobacteria. Envelope proteins initially approach their functional locations from the exterior rather than the interior. In many cases, they have been shown to use components of the general import pathway that also serves the stroma and thylakoids. If the ancient prokaryotic protein sorting machineries are still used for chloroplast envelope proteins, their activities must have been modified or combined with the general import pathway. In this review, we analyze the current knowledge pertaining to chloroplast envelope biogenesis and compare this to bacteria. PMID- 30291510 TI - Extended mutualism between termites and gut microbes: nutritional symbionts contribute to nest hygiene. AB - All higher eukaryotes have established symbiotic relationships with diverse microorganisms. One of the most well-characterized symbiotic systems is that of termites and their intestinal microorganisms, which digest cellulose. Recently, diverse types of symbioses between gut microbes and host organisms including humans have received growing attention for various features of their complex interactions beyond nutrition. In termites, researchers are beginning to explore such function of gut symbionts, but only the contribution to internal immunity against entomopathogen is known in a few species. Here, we report that gut symbionts of the dampwood termite Zootermopsis nevadensis protect nests from the spread of the commensal bacterium Serratia marcescens, which has pathogenic potential. Defaunated termites dispersed S. marcescens in the surrounding environment by feeding on the bacteria, which then survived passage through their alimentary tracts, while non-defaunated termites did not. Loss of gut symbionts caused a significant reduction in intestinal acetate, which is an important carbon source for termites. Culture experiments showed that acetate had significant inhibitory effects on S. marcescens at a concentration as low as 12 mM, which indicated that the intestinal acetate of non-defaunated termites (40 130 mM) was capable of suppressing this bacterium. These results suggest that digestive derivatives produced by intestinal symbionts play an essential role in nest hygiene in addition to their nutritional function for termites. Our study provides a better understanding of the multifunctionality of symbiotic relationships in diverse organisms beyond nutrition. PMID- 30291511 TI - CAIX and pax-8 Commonly Immunoreactive in Endolymphatic Sac Tumors: A Clinicopathologic Study of 26 Cases with Differential Considerations for Metastatic Renal Cell Carcinoma in von Hippel-Lindau Patients. AB - Endolymphatic sac tumors (ELSTs) are rare, slowly growing temporal bone neoplasms which show a high association with von Hippel-Lindau (VHL) syndrome. The immunohistochemistry evaluation of these papillary-cystic neoplasms frequently raises the differential diagnosis with renal cell carcinoma, among other metastatic neoplasms, whether in VHL patients or not. A cohort of 26 patients with ELSTs were evaluated for histologic features, immunohistochemistry findings, and association with VHL. Standard immunohistochemistry evaluation was performed. Sixteen females and 10 males ranging in age from 10 to 69 years (mean 44; VHL mean: 32) at initial presentation, comprised the cohort of patients. Most (86%) experienced hearing changes or inner ear symptoms (vertigo, dizziness), with an average duration of symptoms for 39 months (range 2-240 months). The tumors were an average of 2.9 cm (range 0.4-8 cm), with 14 left, 11 right sided and one bilateral tumor. Nine patients had documented VHL, with 3 patients having a concurrent or subsequent clear cell renal cell carcinoma. Patients were followed an average of 6.2 years (available in 24 patients): 19 alive without disease, 7.5 years; 2 dead without disease, 1.2 years; and 3 alive with disease, 3.1 years. The neoplastic cells show the following immunohistochemistry findings: AE1/AE3, EMA, CK7, CAIX, GLUT1, VEGF: 100% of cases tested were positive; pax-8: 85% of cases positive; CD10 and RCC: 0% of cases reactive. Based on this cohort of 26 patients with ELST, 9 of whom had VHL, the strong pax-8 and CAIX should be used in conjunction with negative CD10 and RCC to help exclude a metastatic renal cell carcinoma. As CAIX is an enzyme overexpressed in hypoxia and hypoxia inducible factor is what VHL protein regulates, this is an expected, although previously unreported finding. Whether part of VHL or not, VHL mutations may be a somatic rather than germline finding in the tumors, a possible further explanation for the CAIX reaction. PMID- 30291512 TI - Ischemic heart disease in Latin American women current perspective and call to action. AB - Cardiovascular diseases (CVDs) constitute the main cause of death in Latin America (LA), with ischemic heart disease (IHD) as the principal cause in most countries. Women are particularly at risk of premature death by CVDs. Nevertheless, in LA, as in other parts of the world, there is a misconception at public level of the importance of CVDs in women; thus, CVDs do not get as much coverage as breast cancer campaigns. Women frequently have atypical symptoms and nonobstructive coronary artery disease as well as inequity in medical and interventional treatments; therefore, care should be built upon these differences. We show the epidemiological situation of IHD in LA women and present a strategy to face the problem, considering the control of risk factors, the optimized utilization of available resources, and the role of research. The role of the International Atomic Energy Agency is highlighted. To adequately face the problem of CVD in LA women, a coordinated approach is necessary, involving medical professionals, governments, scientific societies, and international organizations, as well as the population concerned. In low- and middle-income countries, where the best use of available financial and technological resources is mandatory, a clinical management combining prevention, guidelines, and clinical judgment is required. PMID- 30291513 TI - Improvement in hydrogen binding ability of closo-dicarboranes via functionalization and designing of extended frameworks. AB - Neutral closo-dicarboboranes are reported to have very low H2 binding ability. Herein, we report an improvement in H2 binding energy (Eb) of C2B4H6 by substituting H atoms with different functional groups like X = F, Cl, Br, and XY = BO, CN and NC via quantum-chemical density functional theory based computations. In going from B6H62- to C2B4H6, the Eb value is reduced from 14.6 kJ mol-1 to 2.7 kJ mol-1. C2B4X6 and C2B4(XY)6 systems, which can bind a total of eight H2 molecules, with one H2 molecule occupying at each B-B-C face, possess an Eb value per H2 in the range of 4.5 kJ mol-1 for X = F, 3.9 kJ mol-1 for X = Cl, 5.9 kJ mol-1 for X = Br, 6.8 kJ mol-1 for XY = BO, 5.8 kJ mol-1 for XY = CN and 5.2 kJ mol-1 for XY = NC. The improvement in Eb value is found to be the highest in case of C2B4(BO)6, which has the ability to bind 6.6 gravimetric wt% of H2. The situation can be made more favorable by applying an external electric field. Energy decomposition analysis reveals that although the dispersion interaction (ca. 55-65%) has significant role in binding H2 with such types of molecules, contribution from electrostatic and orbital interaction is also considerable. Further, we modeled an extended system by linking C2B4(BO)n through 'C = C' units for H2 storage purpose. The energy difference between the highest occupied and the lowest unoccupied molecular orbitals gradually lessens with the increase in molecular length. Therefore, it can be tuned gradually by controlling the chain length, which may further open up their potency in the field of electronics. Graphical abstract C2B4X6 (X = F, Cl, Br) and C2B4(XY)6 (XY = BO, CN, NC) show enhanced H2 binding ability from C2B4H6. Further, 1D, 2D and 3-D frameworks can be built by joining C2B4(BO)n units via 'C = C' linkage. PMID- 30291514 TI - Intravenous thrombolysis for ischemic stroke in the Veneto region: the gap between eligibility and reality. AB - Intravenous thrombolysis (IVT) is the treatment of choice for most patients with acute ischemic stroke. According to the recently updated guidelines, IVT should be administered in absence of absolute exclusion criteria. We aimed to assess the proportion of ischemic strokes potentially eligible and actually treated with IVT, and to explore the reasons for not administering IVT. We prospectively collected and analyzed data from 1184 consecutive ischemic stroke patients admitted to the 22 Stroke Units (SUs) of the Veneto region from September 18th to December 10th 2017. Patients were treated with IVT according to the current Italian guidelines. For untreated patients, the reasons for not administering IVT were reported by each center in a predefined model including absolute and/or relative exclusion criteria and other possible reasons. Out of 841 (71%) patients who presented within 4.5 h of stroke onset, 704 (59%) had no other absolute exclusion criteria and were therefore potentially eligible for IVT according to the current guidelines. However, only 323 (27%) patients were eventually treated with IVT. Among 861 (73%) untreated patients, 480 had at least one absolute exclusion criterion, 283 only relative exclusion criteria, 56 only other reasons, and 42 a combination of relative exclusion criteria and other reasons. Our study showed that only 46% (323/704) of the potentially eligible patients were actually treated with IVT in the SUs of the Veneto region. All healthcare professionals involved in the acute stroke pathway should make an effort to bridge this gap between eligibility and reality. PMID- 30291515 TI - CKD-MBD: from the Pathogenesis to the Identification and Development of Potential Novel Therapeutic Targets. AB - PURPOSE OF REVIEW: Although we have seen tremendous advances in the comprehension of CKD-MBD pathophysiology during the last few years, this was not accompanied by a significant change in mortality rate and quality of life. This review will address the traditional and updated pathophysiology of CKD-MBD along with the therapeutic limitations that affect CKD-MBD and proposed alternative treatment targets. RECENT FINDINGS: An innovative concept brings the osteocyte to the center of CKD-MBD pathophysiology, in contrast to the traditional view of the skeleton as a target organ for disturbances in calcium, phosphate, parathyroid hormone, and vitamin D. Osteocytes, through the synthesis of FGF-23, sclerostin, among others, are able to interact with other organs, making bone an endocrine organ. Thus, osteocyte dysregulation might be an early event during the course of CKD. This review will revisit general concepts on the pathophysiology of CKD-MBD and discuss new perspectives for its treatment. PMID- 30291517 TI - Toxic Metals and Trace Elements in Artisanal Honeys from the Canary Islands. AB - Honey is a natural product made by honey bees from the nectar of flowers or secretions produced by other living plant parts. The metal content of the honeys is related to the levels of metals in the environment. Due to the importance of honey in the human diet and the increase of environmental pollution, it is necessary to determine the content of metals in honey to evaluate the toxicological risk derived from its consumption. The objective of this study was to determine the content of 20 metals (Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Sr, V, and Zn) in different samples of artisanal honey from the Canary Islands (Spain) in order to evaluate the dietary intake derived from the consumption of these honeys. A total of 161 samples of different types of Canary honey were analyzed by ICP-OES (inductively coupled plasma-optical emission spectrometry). K (825 mg/kg) was the macroelement found in highest concentration, while B (4.25 mg/kg) was the trace element with the highest mean concentration. Al (3.33 mg/kg) was the most abundant toxic metal, followed by Pb (0.040 mg/kg) and Cd (0.002 mg/kg). A mean consumption of 25 g/day of honey mainly contributes to the recommended daily intake of Cu (1.34% adults) and K (0.67% adults). As regards the toxic metals, the contribution percentage to the TDI (tolerable daily intake) of Pb at 2.92% for adults is noteworthy. However, the consumption of honey does not imply a high intake of metals and, therefore, does pose a risk to the health of adult men and women. PMID- 30291518 TI - Effect of Fe and Cd Co-Exposure on Testicular Steroid Metabolism, Morphometry, and Spermatogenesis in Mice. AB - The mechanism of testicular toxicity of simultaneous multiple exposures to metals is poorly understood. Previous studies reported that the toxic effect of cadmium (Cd) is modified by tissue concentration of iron (Fe). Using the mice (Mus musculus) model in the present study, we demonstrated that combined Cd (25 mg kg 1 bw) and Fe (100 mg kg-1 bw) treatment increased both Cd and Fe testicular concentrations much more than separate exposures to either of the metals. Intratesticular Cd and Fe concentrations were inversely correlated (r = - 0.731, p < 0.05) on administration of Fe but not on combined exposure to both metals when they were positively correlated (versus Cd; r = 0.793, versus Fe; r = 0.779, p < 0.05). Additionally, Cd + Fe treatment increased testicular lipid peroxidation and depleted intratestesticular testosterone, cholesterol and glutathione concentrations much more than their separate treatment. This was also associated with decreased activity of the germ cell marker, testicular lactate dehydrogenase, and increased testicular myeloperoxidase activity. These changes resulted in decreased seminiferous epithelial height, tubular diameter, germ cell (spermatogonia, spermatocytes, and spermatids) numbers, and severe tissue damage. In conclusion, Cd + Fe intake have synergistic toxic effects on testicular steroid formation and spermatogenesis due to the high testicular concentrations of both metals. PMID- 30291516 TI - Obesity and Pulmonary Hypertension. AB - PURPOSE OF REVIEW: Whether the present obesity epidemic will increase the prevalence of pulmonary hypertension over the next decades is unclear. We review the obesity-related mechanisms that may further the development and progression of pulmonary hypertension. RECENT FINDINGS: Systemic and local inflammation, insulin resistance and oxidative stress contribute to the pathobiology of obesity and pulmonary arterial hypertension. Preliminary data suggest that expansion of adipose tissue surrounding the pulmonary artery may hasten the progression of pulmonary arterial hypertension in obese persons. Further, obesity-associated cardiac and pulmonary conditions may increase the prevalence of groups 2 and 3 pulmonary hypertension. The obesity epidemic is likely to increase the prevalence of pulmonary arterial hypertension by enabling vascular remodeling. Obesity associated cardiac and pulmonary conditions will increase pulmonary hypertension prevalence. PMID- 30291519 TI - Macrophage polarization as a novel weapon in conditioning tumor microenvironment for bladder cancer: can we turn demons into gods? AB - Macrophages are major components of the immune infiltration in cancer where they can affect tumor behavior. In the bladder, they play important roles during the resolution of infectious processes and they have been associated with a worse clinical prognosis in bladder cancer. The present review focused on the characteristics of these important immune cells, not only eliciting an innate immune surveillance, but also on their importance during the cancer immunoediting process. We further discuss the potential of targeting macrophages for anticancer therapy, the current strategies and the state of the art as well as the foreseen role on combined therapies on the near future. This review shows how a comprehensive understanding of macrophages within the tumor should translate to better clinical outcome and new therapeutic strategies focusing especially on bladder cancer.

AB - PURPOSE OF REVIEW: Migraine is a disabling and prevalent neurological disease, commonly affecting women during their reproductive years. It is crucial for providers to be able to adequately counsel women who are pregnant, planning pregnancy, or nursing, regarding preventive and abortive treatment options for episodic migraine. This review will discuss (1) the expected course of migraine during pregnancy and the post-partum period, (2) recommended preventive therapies for migraine during pregnancy and lactation, and (3) recommended abortive medications for migraine during pregnancy and lactation. RECENT FINDINGS: Recent research has indicated safety for triptan use during pregnancy and ibuprofen use during the first trimester of pregnancy. Considerations for use of emerging migraine-preventive treatment, such as non-invasive neurostimulators, are discussed. For clinical decision-making and patient counseling, it is important to understand both the limitations in determining teratogenic effects in humans and the principles affecting medication transmission from mother to breast milk. PMID- 30291523 TI - Effects of pseudoephedrine on parameters affecting exercise performance: a meta analysis. AB - BACKGROUND: Pseudoephedrine (PSE), a sympathomimetic drug, commonly used in nasal decongestants, is currently banned in sports by the World Anti-Doping Agency (WADA), as its stimulant activity is claimed to enhance performance. This meta analysis described the effects of PSE on factors relating to sport performance. METHODS: All included studies were randomised placebo-controlled trials and were conducted in a double blind crossover fashion. All participants (males and females) were deemed to be healthy. For the primary analysis, standardised mean difference effect sizes (ES) were calculated for heart rate (HR), time trial (TT) performance, rating of perceived exertion, blood glucose, and blood lactate. RESULTS: Across all parameters, effects were trivial with the exception of HR, which showed a small positive increase in favour of PSE ingestion (ES = 0.43; 95% confidence interval: - 0.01 to 0.88). However, subgroup analyses revealed important trends. Effect sizes for HR (increase) and TT (quicker) were larger in well-trained (VO2 max (maximal oxygen consumption) >= 65 ml/kg/min) and younger (< 28 years) participants, for shorter (< 25 mins) bouts of exercise and when PSE was administered less than 90 min prior to performance. There was evidence of a dose-response effect for TT and HR with larger doses (> 170 mg) resulting in small (ES = - 0.24) and moderate (ES = 0.85) effect sizes respectively for these variables. CONCLUSIONS: We conclude, however, that the performance benefit of pseudoephedrine is marginal and likely to be less than that obtained from permitted stimulants such as caffeine. PMID- 30291524 TI - Evaluation of silicon membranes for extracorporeal membrane oxygenation (ECMO). AB - While extracorporeal membrane oxygenation (ECMO) is a valuable therapy for patients with lung or heart failure, clinical use of ECMO remains limited due to hemocompatibility concerns with pro-coagulatory hollow fiber membrane geometries. Previously, we demonstrated the feasibility of silicon nanopore (SNM) and micropore (SMUM) membranes for transport between two liquid-phase compartments in blood-contacting devices. Herein, we investigate various pore sizes of SNM and SMUM membranes - alone or with a polydimethylsiloxane (PDMS) protective coating - for parameters that determine suitability for gas exchange. We characterized the bubble or rupture point of these membranes to determine sweep gas pressures at which gas emboli would form. The smallest pore size SNM and the SMUM with PDMS coating could be pressurized in excess of 260 cmHg without rupture, which is comparable to hollow fiber sweep gas pressures. Oxygen flux for the SMUM with and without PDMS was insignificantly different at 0.0306 +/- 0.0028 and 0.0297 +/- 0.0012 mL/min, respectively, while SNM flux was significantly lower at 0.0149 +/- 0.0040 mL/min. However, the area-normalized mass transfer coefficient of the SNM was 338 +/- 54 mL O2 m-2 min-1 cmHg-1 - an order of magnitude higher than that of the SMUM with and without PDMS (57.3 +/- 5.5 and 55.6 +/- 2.2 mL O2 m-2 min-1 cmHg-1). Ultimately, we conclude that SMUM-PDMS may make effective membranes for ECMO, since they are both mechanically robust and capable of high oxygen flux. PMID- 30291525 TI - The European Diploma in Radiology (EDiR): investing in the future of the new generations of radiologists. AB - This review aims to describe the organisation and the content of the European Diploma in Radiology (EDiR). The EDiR examination is available to radiologists and radiology residents in their last year of training. It certifies that their levels of knowledge and competency are in line with the ESR European Training Curriculum for Radiology (ETC) of the European Society of Radiology (ESR). The EDiR is an additional qualification of excellence, which serves the standardisation and accreditation of radiologists across European borders. It provides an international benchmark for general radiology and is officially and fully endorsed by the European Union of Medical Specialists (UEMS) and the ESR. The EDiR is recognised as an equivalent of the Polish exit training examination, the first part of the Turkish board examination and the image interpretation part of the Finnish national examination. Moreover, in order to practice radiology in The Netherlands, trainees must either pass their national board examination or the EDiR. It has significant value in many other countries. The examination consists of three parts: Multiple Response Questions (MRQs), Short Cases (SCs) and the Clinically Oriented Reasoning Evaluation (CORE). The committees that form the EDiR Scientific Board follow a structured workflow to prepare each examination, ensuring an adequate peer review system for quality assurance. KEY POINTS: * EDiR helps to standardise radiology training. * EDiR is an international certification method established across Europe. * Ideally all training programmes should embrace EDiR as exit examination after completing their training period. * The EDiR exam consists of multiple response questions, short cases and the Clinically Oriented Reasoning Evaluation.

PMID- 30291527 TI - Which is the proper reference tissue for measuring the change in FDG PET metabolic volume of cardiac sarcoidosis before and after steroid therapy? AB - BACKGROUND: Cardiac sarcoidosis (CS) is a rare but potentially life-threatening disease that causes conduction disturbance, systolic dysfunction, and, most notably, sudden cardiac death. 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) plays important roles not only in diagnosing CS but also in evaluating the effects of anti-inflammatory therapy. A volume-based analysis of parameters measured by FDG PET, so-called cardiac metabolic volume (CMV), has emerged as a new assessment tool. CMV is measured as the volume within the boundary determined by a reference tissue such as the liver and the blood pool uptake. However, there is a possibility that oral steroid therapy could lead to variations of the liver and the blood pool uptake. Here, we attempted to evaluate the steroid effects on the liver and the blood pool uptake. A total of 38 CS patients who underwent FDG PET/CT before and during steroid therapy were retrospectively enrolled. Volumes of interest (VOIs) were placed in the right lobe of the liver and descending aorta (DA). The maximum standardized uptake value (SUVmax), SUVmean, and SUVpeak of the liver and DA were compared between time points before and during steroid therapy. RESULTS: The SUVmax, SUVmean, and SUVpeak of the liver during steroid therapy significantly increased from the time point before the therapy (SUVmax 3.5 +/- 0.4 vs. 3.8 +/- 0.6, p = 0.014; SUVmean 2.7 +/- 0.3 vs. 3.0 +/- 0.5, p = 0.0065; SUVpeak 3.0 +/- 0.4 vs. 3.4 +/- 0.6, p = 0.006). However, the SUVmax, SUVmean, and SUVpeak in the DA did not significantly change (SUVmax 2.2 +/- 0.3 vs. 2.2 +/- 0.4, p = 0.46; SUVmean 1.9 +/- 0.3 vs. 2.0 +/- 0.4, p = 0.56; SUVpeak 2.0 +/- 0.3 vs. 2.0 +/- 0.3, p = 0.70). CONCLUSIONS: We measured FDG uptake in the liver and blood pool before and during steroid therapy. Steroid therapy increased the liver uptake but not the blood pool uptake. Our findings suggested that the DA uptake is a more suitable threshold than liver uptake to evaluate therapeutic effects using volume-based analysis of cardiac FDG PET. PMID- 30291526 TI - Novel Imaging Biomarkers for Huntington's Disease and Other Hereditary Choreas. AB - PURPOSE OF THE REVIEW: Imaging biomarkers for neurodegenerative disorders are primarily developed with the goal to aid diagnosis, to monitor disease progression, and to assess the efficacy of disease-modifying therapies in support to clinical outcomes that may either show limited sensitivity or need extended time for their evaluation. This article will review the most recent concepts and findings in the field of neuroimaging applied to Huntington's disease and Huntington-like syndromes. Emphasis will be given to the discussion of potential pharmacodynamic biomarkers for clinical trials in Huntington's disease (HD) and of neuroimaging tools that can be used as diagnostic biomarkers in HD-like syndromes. RECENT FINDINGS: Several magnetic resonance (MR) and positron emission tomography (PET) molecular imaging tools have been identified as potential pharmacodynamic biomarkers and others are in the pipeline after preclinical validation. MRI and 18F-fluorodeoxyglucose PET can be considered useful supportive diagnostic tools for the differentiation of other HD-like syndromes. New trials in HD have the primary goal to lower mutant huntingtin (mHTT) protein levels in the brain in order to reduce or alter the progression of the disease. MR and PET molecular imaging markers have been developed as tools to monitor disease progression and to evaluate treatment outcomes of disease-modifying trials in HD. These markers could be used alone or in combination for detecting structural and pharmacodynamic changes potentially associated with the lowering of mHTT. PMID- 30291529 TI - Apgar score and risk of autism. AB - Low Apgar score has been associated with higher risk for several neurological and psychiatric disorders, including cerebral palsy and intellectual disability. Studies of the association between Apgar score and autism spectrum disorder (ASD) have been inconsistent. We aimed to investigate (1) the association between low Apgar score at 5 min and risk for ASD, and (2) the modifying effects of gestational age and sex on this association in the largest multinational database of ASD. We included prospective data from 5.5 million individuals and over 33,000 cases of ASD from Norway, Sweden, Denmark and Western Australia who were born between 1984 and 2007. We calculated crude and adjusted risk ratios (RR) with 95% confidence intervals (95% CIs) for the associations between low Apgar score and ASD. All analyses for ASD were repeated for autistic disorder (AD). We used interaction terms and stratified analysis to investigate the effects of sex, gestational age, and birth weight on the association. In fully adjusted models, low Apgar scores (1-3) (RR, 1.42; 95% CI, 1.16-1.74), and intermediate Apgar scores (4-6) (RR, 1.50; 95% CI, 1.36-1.65) were associated with a higher RR of ASD than optimal Apgar score (7-10). The point estimates for low (RR, 1.88; 95% CI, 1.41-2.51) and intermediate Apgar score (RR, 1.54; 95% CI, 1.32-1.81) were larger for AD than for ASD. This study suggests that low Apgar score is associated with higher risk of ASD, and in particular AD. We did not observe any major modifying effects of gestational age and sex, although there seems to be substantial confounding by gestational age and birth weight on the observed association.

PMID- 30291531 TI - Does Religion Predict Health-Promoting Behaviors in Community-Dwelling Elderly People? AB - As the aging phenomenon gains importance in many societies, regular health promoting activities by the elderlies become more crucial for disability reduction and their health promotion. Religious viewpoints and perspectives can have an influence on the individuals' assessment of life events. Recent studies show a correlation between religiosity and mental health. However, there is limited number of studies on the relationship between religiosity and health behaviors, especially in elderly. The purpose of this research is to evaluate religion's predictive power in health-improving behaviors of the elderly. This cross-sectional study was conducted on 316 community-dwelling elderly with the mean age of 67.9 +/- 6.6 years, who were functionally independent without cognitive or mental impairments. Health-promoting lifestyle profile 2 assessment (HPLP2) and Alport questionnaires were used to assess health behaviors and religious orientation, respectively. Data analysis was performed by independent T test and multiple linear regression models with SPSS version 23. An internal religious orientation was found in 71 elderly; this accounts for 22.5% of the study population. Based on the health behavior scoring 154 individuals, 48.8% of the study population obtained a score of higher or equal to 139. These individuals were placed on third quartile and higher. Among the health behavior components, "the health responsibility" was the only component related to religious orientation [internal 25.1 +/- 6.6 (P < 0.001, r = 0.78) vs. external 22.6 +/- 6.5 (P > 0.05, r = 0.22)]. Based on the multiple linear regression models, no significant relationship was found between total health behavior score and religious orientation. However, a significant relationship existed between the participants' health behaviors and some of their profile. The results indicate that despite good health behaviors in nearly half of the elderlies, no significant relationship was found between health behavior and religious orientation. The results suggest possible impact of other religion-related concepts including private religious behaviors, devotion, spiritual transcendence, religious adaptation, and religious traditions and experiences on the health behaviors. These concepts require further study for better understanding of their impact. PMID- 30291532 TI - Investigating the Effect of Religious Intervention on Mental Vitality and Sense of Loneliness Among the Elderly Referring to Community Healthcare Centers. AB - The growth of elderly population is among the most important issues in the world, and religious interventions can help them to keep their health. For this reason, this study was conducted with the aim of determining the effect of religious intervention on subjective vitality and sense of loneliness of the elderly referring to healthcare centers. This semi-experimental study was conducted on 88 elderlies referring to community healthcare centers of Ilam City. The elderlies were randomly assigned into test and control groups, and subjective vitality and sense of loneliness questionnaire was distributed to them. For the elderly in the test group, twelve 30-45-min sessions of religious intervention were held. Then, at intervals of immediately, 1 month, and 2 months after the study, the studied questionnaires were redistributed again among the elderly, and the data were analyzed using SPSS 16 and through descriptive statistics as well as repeated measures of analysis of variance. Before intervention, there was no difference between mental vitality and fear of loneliness in the elderly, but after intervention, the amount of mental vitality increased and fear of loneliness decreased. Since in this study, implementation of religious intervention resulted in improved subjective vitality and diminished sense of loneliness among the elderly, it is suggested that this effective intervention be also used in other studies. PMID- 30291533 TI - Religiously/Spiritually Involved, but in Doubt or Disbelief-Why? Healthy? AB - The question of why atheists and agnostic theists attend religious services and pray (and what that might mean for their health) is examined through (1) a thematic analysis of commentaries, perspective pieces, and news articles from the popular literature, and (2) a critical review of scholarly research involving comparisons between religious and nonreligious individuals on a variety of health related outcomes. Findings suggest that atheists and agnostic theists can take pleasure in attending religious services, and they may be driven to pray at times. In many cases, this was explained by their efforts to stay connected and avoid or manage conflict with family members. Despite a pattern of friction between nonbelievers and believers across the dataset, they predominantly agreed on the whys and wherefores of religious service attendance and the prospect that congregants could "bridge the worlds of belief and nonbelief." The themes identified are intended to inform the development of qualitative interview protocols and survey instruments. Although health was not among the most salient themes in the narratives analyzed here, many of the reasons cited for religious service attendance and prayer can be tied to existing literature that has relevance for health. Atheists who experience dissonance between their self perception and nonbelief in God-and agnostic theists who are prone to existential uncertainty and have only moderate faith-might experience poorer health outcomes. Recommendations focus on the need to (a) supplement secondary analyses of archival survey data with qualitative descriptions of belief systems within groups, and (b) move away from the adversarial stance taken by some of the authors of recently published studies on atheism, nonreligion, and health. PMID- 30291534 TI - Structural basis of the nonribosomal codes for nonproteinogenic amino acid selective adenylation enzymes in the biosynthesis of natural products. AB - Nonproteinogenic amino acids are the unique building blocks of nonribosomal peptides (NRPs) and hybrid nonribosomal peptide-polyketides (NRP-PKs) and contribute to their diversity of chemical structures and biological activities. In the biosynthesis of NRPs and NRP-PKs, adenylation enzymes select and activate an amino acid substrate as an aminoacyl adenylate, which reacts with the thiol of the holo form of the carrier protein to afford an aminoacyl thioester as the electrophile for the condensation reaction. Therefore, the substrate specificity of adenylation enzymes is a key determinant of the structure of NRPs and NRP-PKs. Here, we focus on nonproteinogenic amino acid selective adenylation enzymes, because understanding their unique selection mechanisms will lead to accurate functional predictions and protein engineering toward the rational biosynthesis of designed molecules containing amino acids. Based on recent progress in the structural analysis of adenylation enzymes, we discuss the nonribosomal codes of nonproteinogenic amino acid selective adenylation enzymes. PMID- 30291536 TI - Differences in Stability, Activity and Mutation Effects Between Human and Mouse Leucine-Rich Repeat Kinase 2. AB - Mutations in the Leucine-rich repeat kinase 2 (LRRK2) gene have been implicated in the pathogenesis of Parkinson's disease (PD). Identification of PD-associated LRRK2 mutations has led to the development of novel animal models, primarily in mice. However, the characteristics of human LRRK2 and mouse Lrrk2 protein have not previously been directly compared. Here we show that proteins from different species have different biochemical properties, with the mouse protein being more stable but having significantly lower kinase activity compared to the human orthologue. In examining the effects of PD-associated mutations and risk factors on protein function, we found that conserved substitutions such as G2019S affect human and mouse LRRK2 proteins similarly, but variation around position 2385, which is not fully conserved between humans and mice, induces divergent in vitro behavior. Overall our results indicate that structural differences between human and mouse LRRK2 are likely responsible for the different properties we have observed for these two species of LRRK2 protein. These results have implications for disease modelling of LRRK2 mutations in mice and on the testing of pharmacological therapies in animals. PMID- 30291535 TI - Association of ERG/PTEN status with biochemical recurrence after radical prostatectomy for clinically localized prostate cancer. AB - We have previously demonstrated a significant correlative relationship between PTEN deletion and ERG rearrangement, both in the development of clinically localized prostate cancers and metastases. Herein, we evaluate the cooperative role of ERG and PTEN in oncological outcomes after radical prostatectomy for clinically localized prostate cancer. We evaluated ERG and PTEN status using three previously described cohorts. The first cohort included 235 clinically localized prostate cancer cases represented on tissue microarrays (TMA), evaluated using previously validated FISH assays for ERG and PTEN. The second cohort included 167 cases of clinically localized prostate cancer on TMAs evaluated for PTEN by FISH, and for PTEN and ERG by dual IHC. The third cohort comprised 59 clinically localized prostate cancer cases assessed by array comparative genomic hybridization (aCGH). Kaplan-Meir plots and long rank tests were used to assess the association of ERG and PTEN status with biochemical recurrence after radical prostatectomy for clinically localized prostate cancer. Of the 317 cases eligible for analyses with evaluable ERG and PTEN status, 88 (27.8%) patients developed biochemical recurrence over a median follow-up of 5.7 years. Overall, 45% (142/317) of cases demonstrated ERG rearrangement and 20% (62/317) of cases demonstrated PTEN loss. Hemizygous and homozygous deletion of PTEN was seen in 10% (18/175) and 3% (5/175) of ERG-negative cases, respectively. In contrast, hemizygous and homozygous deletion of PTEN was seen in 11% (15/142) and 17% (24/123) of ERG-positive cases, respectively. PTEN loss (heterozygous or homozygous) was significantly associated with shorter time to biochemical recurrence compared to no PTEN loss (p < 0.001). However, ERG rearrangement versus no rearrangement was not associated with time to PSA recurrence (p = 0.15). Patients who exhibited ERG rearrangement and loss of PTEN had no significant difference in time to recurrence compared to patients with wild-type ERG and loss of PTEN (p = 0.30). Our findings confirm a mutual cooperative role of ERG and PTEN in the pathogenesis of prostate cancer, particularly for homozygous PTEN deletion. ERG did not stratify outcome either alone or in combination with PTEN in this cohort. PMID- 30291537 TI - Distinct Cytokine and Chemokine Expression in Plasma and Calpeptin-Treated PBMCs of a Relapsing-Remitting Multiple Sclerosis Patient: A Case Report. AB - The cytokine/chemokine expression signature of a 60-year-old African American male with relapsing-remitting multiple sclerosis (RRMS) was analyzed using patient blood samples obtained from two separate visits to the clinic. Thirty-six different cytokines, chemokines, and growth factors were detected in the plasma of the RRMS patient using a multiplexed bead-based immunoassay. Results indicated that at least ten of these factors with a concentration of > 100 pg/mL are identified as pro-inflammatory. Calpain inhibition led to an anti-inflammatory effect, as indicated by a decrease in expression of pro-inflammatory cytokines/chemokines such as GM-CSF, IFNgamma, and IL-17A, and a relative increase in two of the anti-inflammatory cytokines (IL-13 and IL-4) in the peripheral blood mononuclear cells activated with anti-CD3/CD28. Overall, these results suggest that the unique cytokine/chemokine pattern observed in the plasma of the RRMS patient can be used as a prognostic marker and calpain inhibition may be used as a novel therapeutic strategy for treating excessive inflammatory response specific to RRMS patients. PMID- 30291539 TI - Cerebral arterial time constant calculated from the middle and posterior cerebral arteries in healthy subjects. AB - The cerebral arterial blood volume changes (?CaBV) during a single cardiac cycle can be estimated using transcranial Doppler ultrasonography (TCD) by assuming pulsatile blood inflow, constant, and pulsatile flow forward from large cerebral arteries to resistive arterioles [continuous flow forward (CFF) and pulsatile flow forward (PFF)]. In this way, two alternative methods of cerebral arterial compliance (Ca) estimation are possible. Recently, we proposed a TCD-derived index, named the time constant of the cerebral arterial bed (tau), which is a product of Ca and cerebrovascular resistance and is independent of the diameter of the insonated vessel. In this study, we aim to examine whether the tau estimated by either the CFF or the PFF model differs when calculated from the middle cerebral artery (MCA) and the posterior cerebral artery (PCA). The arterial blood pressure and TCD cerebral blood flow velocity (CBFVa) in the MCA and in the PCA were non-invasively measured in 32 young, healthy volunteers (median age: 24, minimum age: 18, maximum age: 31). The tau was calculated using both the PFF and CFF models from the MCA and the PCA and compared using a non parametric Wilcoxon signed-rank test. Results are presented as medians (25th-75th percentiles). The cerebrovascular time constant estimated in both arteries using the PFF model was shorter than when using the CFF model (ms): [64.83 (41.22 104.93) vs. 178.60 (160.40-216.70), p < 0.001 in the MCA, and 44.04 (17.15-81.17) vs. 183.50 (153.65-204.10), p < 0.001 in the PCA, respectively]. The tau obtained using the PFF model was significantly longer from the MCA than from the PCA, p = 0.004. No difference was found in the tau when calculated using the CFF model. Longer tau from the MCA might be related to the higher Ca of the MCA than that of the PCA. Our results demonstrate MCA-PCA differences in the tau, but only when the PFF model was applied. PMID- 30291538 TI - Evaluation of expressive writing for postpartum health: a randomised controlled trial. AB - Pregnancy, birth and adjusting to a new baby is a potentially stressful time that can negatively affect the health of women. There is some evidence that expressive writing can have positive effects on psychological and physical health, particularly during stressful periods. The current study aimed to evaluate whether expressive writing would improve women's postpartum health. A randomized controlled trial was conducted with three conditions: expressive writing (n = 188), a control writing task (n = 213), or normal care (n = 163). Measures of psychological health, physical health and quality of life were measured at baseline (6-12 weeks postpartum), 1 and 6 months later. Ratings of stress were taken before and after the expressive writing task. Intent-to-treat analyses showed no significant differences between women in the expressive writing, control writing and normal care groups on measures of physical health, anxiety, depression, mood or quality of life at 1 and 6 months. Uptake and adherence to the writing tasks was low. However, women in the expressive writing group rated their stress as significantly reduced after completing the task. Cost analysis suggest women who did expressive writing had the lowest costs in terms of healthcare service use and lowest cost per unit of improvement in quality of life. Results suggest expressive writing is not effective as a universal intervention for all women 6-12 weeks postpartum. Future research should examine expressive writing as a targeted intervention for women in high-risk groups, such as those with mild or moderate depression, and further examine cost effectiveness.Clinical trial registration number ISRCTN58399513 www.isrctn.com. PMID- 30291540 TI - Service Coordination by Public Sector Managers in a Human Service Contracting Environment. AB - Despite emerging evidence of contracting for evidence-based practices (EBP), little research has studied how managers lead contract-based human service delivery. A 2015 survey of 193 managers from five San Francisco Bay Area county human service departments examined the relationship between contract-based service coordination (i.e., structuring cross-sector services, coordinating client referrals and eligibility, overseeing EBP implementation) and the predictors of managerial role, involvement, and boundary spanning. Multivariate regression results suggested that county managers identified fewer service coordination challenges if they were at the executive and program levels, had greater contract involvement, and engaged in contract-focused boundary spanning. In conclusion, we underscore the organizational and managerial dimensions of contract-based service delivery. PMID- 30291541 TI - Four new species of dactylogyrids (Monogenea: Dactylogyridae) parasitic on gills of labrid and sparid fishes from Southeastern Pacific Ocean off Peru. AB - During a research on gill ectoparasites of Peruvian marine fishes, four dactylogyrid (Monogenea) species, parasitising two teleost species, Bodianus diplotaenia (Gill) (Labridae) and Calamus brachysomus (Lockington) (Sparidae), were found. Euryhaliotrema luisae n. sp. ex C. brachysomus is differentiated from other congeneric species by the morphology of the male copulatory organ, which comprises a coil of nine counterclockwise rings, and by the morphology of the anchors and bars. Euryhaliotrema magnopharyngis n. sp. ex C. brachysomus can be distinguished from all other congeners by having a well-developed pharynx occupying much of the anterior region and by the ventral bar, which is V-shaped, with well-elongated, thin arms. In addition, E. luisae n. sp. and E. magnopharyngis n. sp. can be differentiated from all other members of Euryhaliotrema Kritsky & Boeger, 2002 by the presence of a glandular oval plate lying on peduncle. Haliotrema diplotaenia n. sp. ex B. diplotaenia is characterised by the structure of the male copulatory organ, comprising a tapered shaped cirrus tube with twisted acute tip and a filament-shaped accessory piece with medial and distal expansions, and by the morphology of the ventral bar (inverted W-shaped, with short lateral ends and two anterior conical protuberances). Haliotrema saezae n. sp. ex B. diplotaenia differs from all other members of Haliotrema Johnston & Tiegs, 1922 by having a tubular copulatory organ with curved distal tip and a filament-shaped accessory piece without lateral expansions, and by the morphology of anchors and bars. The present findings are added to the other six marine dactylogyrids previously reported from Peru. PMID- 30291542 TI - Perioperative intervention by oral medicine team in cardiovascular surgery patients. AB - In brief, perioperative oral intervention consists of elimination of odontogenic foci and maintenance of oral hygiene in patients undergoing surgery. The importance of oral intervention before, during, and after medical treatments is well-known, especially in cancer patients, because odontogenic foci such as untreated deep dental caries or periodontitis can cause systemic infection in patients with myelosuppression resulting from chemotherapy. Although perioperative oral intervention is currently recommended for patients with cardiovascular disease, its efficacy in this population has not been established. This article consists of three sections: first, we review the current knowledge about the association between dental disease and cardiovascular disease to show the importance of oral hygiene maintenance and the risks of invasive dental procedures in patients with cardiovascular disease; second, we introduce pertinent, but limited evidence concerning the effect of oral care in preventing postoperative pneumonia; and finally, we present the optimal strategy for perioperative oral intervention in cardiovascular surgery patients. PMID- 30291543 TI - Lipomers (Lipid-polymer Hybrid Particles) of Vardenafil Hydrochloride: a Promising Dual Platform for Modifying the Drug Release Rate and Enhancing Its Oral Bioavailability. AB - Vardenafil hydrochloride is commonly used for the curing of erectile dysfunction. VAR suffers certain limitations: (i) short elimination half-life (4-5 h), (ii) low aqueous solubility (0.11 mg/mL), (iii) susceptibility to extensive first-pass metabolism and drug efflux transporters (P-glycoprotein), and (iv) limited (15%) oral bioavailability. The current study focused on the development of VAR lipomers as promising modified release systems able to enhance oral bioavailability. VAR-lipomers (lipid-polymer complexes) were successfully developed by a modified precipitation technique employing a lipid (polyglyceryl-6 distearate or glyceryl tristearate) and an amphiphilic polymer (Gantrez(r)). Three VAR:lipid ratios [1:1, 1:2, and 1:3] and three VAR:Gantrez(r) ratios [4:1, 2:1, and 1:1] were investigated. Solid-state characterization studies involved differential scanning calorimetry (DSC), X-ray diffraction (XRD), and Fourier transform infrared (FT-IR) spectroscopy. The systems were assessed for particle size, polydispersity index (PDI), zeta-potential, VAR entrapment-efficiency (EE%), morphology, and VAR released % after 2 h (Q2h) and 8 h (Q8h). The best achieved system (the highest desirability) was promoted for pharmacokinetic studies in fasted rabbits. Statistical analysis of data revealed that L9 system (PGDS, VAR, and Gantrez(r); 3:1:1, respectively) had the highest desirability (0.85) with respect to spherical particle size (622.15 nm), PDI (0.11), zeta potential (-27.90 mV), EE% (62.80%), Q2h (43.45%), and Q8h (77.40%). With respect to Levitra(r) tablets, the significantly higher relative bioavailability (170%), delayed Tmax, and extended MRT(0-infinity) clarified the dual ability of L9 system. Lipomers are emerging systems capable of modifying the rate of VAR release and promoting its oral bioavailability. PMID- 30291544 TI - Radiolabeling of Preformed Niosomes with [99mTc]: In Vitro Stability, Biodistribution, and In Vivo Performance. AB - Nanocarriers radiolabeled with [99mTc] can be used for diagnostic imaging and radionuclide therapy, as well as tracking their pharmacokinetic and biodistribution characteristics. Due to the advantages of niosomes as an ideal drug delivery system, in this study, the radiolabeling procedure of niosomes by [99mTc]-HMPAO complexes was investigated and optimized. Glutathione (GSH)-loaded niosomes were prepared using a thin-film hydration method. To label the niosomes with [99mTc], the preformed GSH-loaded niosomes were incubated with the [99mTc] HMPAO complex and were characterized for particle size, size distribution, zeta potential, morphology, and radiolabeling efficiency (RE). The effects of GSH concentration, incubation time, incubation temperature, and niosomal composition on RE were investigated. The biodistribution profile and in vivo SPECT/CT imaging of the niosomes and free [99mTc]-HMPAO were also studied. Based on the results, all vesicles had nano-sized structure (160-235 nm) and negative surface charge. Among the different experimental conditions that were tested, including various incubation times, incubation temperatures, and GSH concentrations, the optimum condition that resulted in a RE of 92% was 200-mM GSH and 15-min incubation at 40 degrees C. The in vitro release study in plasma showed that about 20% of radioactivity was released after 24 h, indicating an acceptable radiolabeling stability in plasma. The biodistribution of niosomes was clearly different from the free radiolabel. Niosomes carrying radionuclide were successfully used for tracking the in vivo disposition of these carriers and SPECT/CT imaging in rats. Furthermore, biodistribution studies in tumor-bearing mice revealed higher tumor accumulation of the niosomal formulation as compared with [99mTc]-HMPAO. PMID- 30291545 TI - The effect of dietary fucoidan on growth, immune functions, blood characteristics and oxidative stress resistance of juvenile red sea bream, Pagrus major. AB - We determined the supplementation effects of dietary fucoidan on growth, immune responses, blood characteristics, and oxidative stress resistance of juvenile red sea bream. A fishmeal (FM)-based basal diet supplemented with 0% (D1, control), 0.05% (D2), 0.1% (D3), 0.2% (D4), 0.4% (D5), and 0.8% (D6) mozuku fucoidan to formulate six experimental diets. Each diet was randomly allocated to triplicate groups of fish (3.8 g) for 60 days. Results showed that fish-fed diet D5 showed significantly higher (P < 0.05) growth performance compared to the control (D1). Diet groups D2 to D4 also showed intermediate values compared to D1. Feed conversion efficiency and protein efficiency ratio were significantly higher in diet group D5, which was not significantly different with D3. Fucoidan supplementation increased whole-body lipid, which was significantly higher in the D5 group. Condition factor (CF) was significantly higher in fish fed >= 0.2% fucoidan-supplemented diet groups. Diet group D5 and D4 showed significantly lower blood urea nitrogen (BUN) and aspartate aminotransferase (AST) level, respectively. Dietary fucoidan reduced the oxidative stress of fish. Among the measured nonspecific immune parameters, only peroxidase activity (PA) and total serum protein (TSP) were significantly influenced by dietary supplementation and it was higher in D4 group. Fucoidan supplementation reduces thiobarbituric acid reactive substance (TBARS) values numerically and it was lowest in fish-fed diet group D5. Under the present experimental condition, finally, we concluded that 0.3-0.4% dietary fucoidan supplementation enhanced the growth and health performance of red sea bream by increasing growth, immune response, blood characteristics, and oxidative stress resistance. PMID- 30291546 TI - Stereotactic Body Radiation Therapy (SBRT) Using CyberKnife in Oligometastatic Cancer Patients; Retrospective Evaluation, Single Institution Experience. AB - OBJECTIVES: We retrospectively evaluate local control rate at 6 months and 1 year in oligometastatic cancer patients treated with SBRT using CyberKnife. METHODS: Total of 21 patients with 24 treatment sites from February 2014 till June 2017 who were treated with SBRT in our institution were included in this study. RESULTS: Eleven patients were males, 10 patients were females, median age at diagnosis was 63 years, and colorectal cancer is the most commonly diagnosed cancer in 18 patients. The abdomino-pelvic lymph nodes were the commonest treatment site in 11 (45.8%), average PTV volume of 46.4 cc. All the patients received SBRT with average (BED) of 97 GY, 7 treatment sites received BED of < 100GYgroup 1, and 17 received BED >= 100GY group 2. No reported G3 or G4 acute or chronic toxicity. The 6 months and 1 year local control (LC) were 95.8 and 88.2%, respectively. After a median follow-up of 16.8 months, 19(90.5%) patients were alive; among them, local progression was observed in 1 (4.1%) treatment site, while systemic progression in 4 (16.6%), and two (9.5%) patients died; they had both local and systemic failures. The 1-year local PFS rate was 82%. In univariate analysis, PTV volume was significantly correlated with LC rate at 6 months (p = 0.001), while the site of metastasis appeared to significantly correlate with PFS (p = 0.03). CONCLUSION: SBRT using CyberKnife is feasible, safe, and effective treatment for oligometastatic sites. Six months and 1 year local control rate is 95.8 and 88.2% respectively in our patients cohort, treatment regimens with higher BED resulting in better 1-year local PFS, although it was not statistically significant. A larger cohort of patients and longer follow up is required for better evaluation. PMID- 30291547 TI - Animation as Supplementary Learning Material About Carcinogenic Liver Fluke in Classes for Primary Schoolchildren. AB - Carcinogenic liver fluke is still an issue of great concern in some countries of Southeast Asia, particularly in Thailand, Cambodia, the Lao People's Democratic Republic, and Vietnam. The infection, caused by Opisthorchis viverrini, is associated to cholangiocarcinoma and is endemic among human populations for whom raw fish is frequently consumed. Prevention and health education are required. Therefore, this study aimed to evaluate the effectiveness of educational intervention to improve knowledge among primary schoolchildren based on animation assisted education. In this study, 80 participants (40 participants in the experimental group and 40 participants in the comparison group) were selected in 2018. The effectiveness of an interactive animation program in improving the knowledge of students studying liver fluke was determined based on scores on tests given before and immediately after completion of a 4.29-min animated program on the liver fluke life cycle, risk factors, disease, diagnosis, treatment, prevention, and control. Data were analyzed using SPSS-22 via paired t tests and independent samples t tests at a significance level of 0.05. A marked and significant improvement was observed in the immediate posttest compared with the pretest scores. More importantly, the students who had used the animated program achieved a significantly higher score on the final test than the comparison group. The results offered in the first report show that the use of the animated program facilitated education about liver fluke. It is strongly believed that animations are good supplementary learning materials for students, particularly for learning about serious concepts. PMID- 30291548 TI - Sensor applications of polypyrrole for oxynitrogen analytes: a DFT study. AB - Density functional theory calculations are performed to evaluate the sensing ability of polypyrrole for oxynitrogen analytes. Interaction energies of PPy-X (X = NO2-, NO2, and NO) are calculated at B3LYP-CP/6-31G(d) and B3LYP/6-31G(d) levels of theory and compared with the high level calibrated method (M05-2X/aug cc-pVDZ). B3LYP-CP/6-31G(d) gives the best correlation with the high level calibrated method compared to B3LYP/6-31G(d). Interaction of oligopyrrole with analytes shows a significant effect on the geometric and electronic properties; the conjugation is increased in the pyrrole oligomers and movement of charge is increased over the polymeric backbone. The charge is transferred from analytes to pyrrole oligomers (except nPy-NO2), and a more pronounced effect of charge transfer is observed in the case of nitrite ion (NO2-) compared to NO. In nPy NO2, the charge is transferred from polymer to analyte. This transfer of charge indicates the n-type doping effect of analytes. The HOMO-LUMO gap decreases after interaction with analytes, which results in a drop of resistance (conductivity increases). These theoretical outcomes are consistent with the experimental results; polypyrrole has more sensing ability toward the nitrite anion (NO2-). Graphical abstract High sensitivity of polypyrrole towards NO over NO2 and NO2. PMID- 30291550 TI - A Short Review of the Treatment of Headaches Using Osteopathic Manipulative Treatment. AB - PURPOSE OF REVIEW: This review highlights the importance of osteopathic manipulative treatment (OMT) in headache sufferers. OMT is a viable option for patients who either do not wish to use pharmaceuticals or who have contraindications to pharmaceuticals. Patients with headaches that are refractory to other treatment options may also be candidates for OMT. Multiple headache etiologies are amenable to this non-invasive treatment option and they will be reviewed here. Although there are advantages to using this treatment method, there are also shortcomings in the literature, which will be discussed. RECENT FINDINGS: Roughly 45 million Americans suffer from headaches every year. Many headache sufferers are unable to find relief through conventional treatment options. OMT is a useful non-invasive treatment option with little to no side effects. There are multiple headache types. Migraine, tension-type headache, combat-related events, post-traumatic headache, sinusitis, tooth extraction, concussions, and others have all shown benefit from OMT. OMT is a non-invasive treatment option for individuals suffering from various types of headaches. This treatment option is tailored to the individual needs of the patient and is delivered by licensed and experienced osteopathic physicians. This review of literature also highlights where there is need for further research in the field. PMID- 30291549 TI - A Critical Exploration of Migraine as a Health Disparity: the Imperative of an Equity-Oriented, Intersectional Approach. AB - PURPOSE OF REVIEW: Despite recognition of rising prevalence and significant burden, migraine remains underestimated, underdiagnosed, and undertreated. This is especially true among groups who have been historically, socially, and economically marginalized such as communities of color, women, people experiencing poverty, people with lower levels of education, and people who hold more than one of these marginalized identities. While there is growing public and professional interest in disparities in migraine prevalence, there is a paucity of research focusing on racial/ethnic and socioeconomic disparities, and the social and structural determinants of health and equity that perpetuate these disparities. From a health equity perspective, migraine research and treatment require an examination not only of biological and behavioral factors, but of these identities and underlying, intersecting social and structural determinants of health. RECENT FINDINGS: Significant disparities in migraine incidence, prevalence, migraine-related pain and disability, access to care, and quality of care persist among marginalized and underserved groups: African Americans, Hispanics, people experiencing poverty, un- or under-employment, the un- and under-insured, people who have been exposed to stressful and traumatic events across the lifespan, and people experiencing multiple, overlapping marginalized identities. These same groups are largely underrepresented in migraine research, despite bearing disproportionate burden. Current approaches to understanding health disparities in migraine largely assume an essentializing approach, i.e., documenting differences between single identity groups-e.g., race or income or education level-rather than considering the mechanisms of disparities: the social and structural determinants of health. While disparities in migraine are becoming more widely acknowledged, we assert that migraine is more aptly understood as a health equity issue, that is, a condition in which many of the health disparities are avoidable. It is important in research and clinical practice to consider perspectives that incorporate a cultural understanding of racial, ethnic, and socioeconomic identity within and across all levels of society. Incorporating perspectives of intersectionality provides a strong foundation for understanding the role of these complex combination of factors on migraine pain and treatment. We urge the adoption of intersectional and systems perspectives in research, clinical practice, and policy to examine (1) interplay of race, gender, and social location as key factors in understanding, diagnosing, and treating migraine, and (2) the complex configurations of social and structural determinants of health that interact to produce health inequities in migraine care. An intentional research and clinical focus on these factors stands to improve how migraine is identified, documented, and treated among marginalized populations. PMID- 30291551 TI - Sustained conscious access to incidental memories in RSVP. AB - In visual search of natural scenes, differentiation of briefly fixated but task irrelevant distractor items from incidental memory is often comparable to explicit memorization. However, many characteristics of incidental memory remain unclear, including the capacity for its conscious retrieval. Here, we examined incidental memory for faces in either upright or inverted orientation using Rapid Serial Visual Presentation (RSVP). Subjects were instructed to detect a target face in a sequence of 8-15 faces cropped from natural scene photographs (Experiment 1). If the target face was identified within a brief time window, the subject proceeded to an incidental memory task. Here, subjects used incidental memory to discriminate between a probe face (a distractor in the RSVP stream) and a novel, foil face. In Experiment 2 we reduced scene-related semantic coherency by intermixing faces from multiple scenes and contrasted incidental memory with explicit memory, a condition where subjects actively memorized each face from the sequence without searching for a target. In both experiments, we measured objective performance (Type 1 AUC) and metacognitive accuracy (Type 2 AUC), revealing sustained and consciously accessible incidental memory for upright and inverted faces. In novel analyses of face categories, we examined whether accuracy or metacognitive judgments are affected by shared semantic features (i.e., similarity in gender, race, age). Similarity enhanced the accuracy of incidental memory discriminations but did not influence metacognition. We conclude that incidental memory is sustained and consciously accessible, is not reliant on scene contexts, and is not enhanced by explicit memorization. PMID- 30291552 TI - Helmets improve estimations of depth and visual angle to safe targets. AB - Egocentric distance estimation has been shown to depend on wearing safety gear, which promotes compensatory behavior, and on target type, which regulates fight or-flight responses. We hypothesized that the two factors interact, possibly in asymmetric fashion, and set out to uncover the limits of this interaction in a perceptual task where individuals wearing helmets or baseball caps estimated egocentric distance to non-threatening and threatening animals depicted on cards (i.e., safe and unsafe targets). We found that, compared to participants wearing caps, participants wearing helmets overshoot distance estimations and were able to distinguish not only between targets situated at two depth levels as participants wearing caps could, but also between safe targets situated at wide and narrow visual angles. Our findings help define the interaction between safety devices and target type, thereby contributing to the debate between advocates of prevention models and those who maintain that these are offset by compensatory strategies. PMID- 30291553 TI - The emotional attentional blink is robust to divided attention. AB - The emotional attentional blink (EAB) refers to a temporary impairment in the ability to identify a target when it is preceded by an emotional distractor. It is thought to occur because the emotional salience of the distractor exogenously captures attention for a brief duration, rendering the target unattended and preventing it from reaching awareness. Here we tested the extent to which the EAB can be attenuated by inducing a diffuse top-down attentional state, which has been shown to improve target identification in an analogous attentional phenomenon, the attentional blink. Rapid sequences of landscape images were presented centrally, and participants reported the orientation of a +/- 90 degrees rotation of a landscape target. To induce a diffuse state of attention, participants were given a secondary task of monitoring for the appearance of a colored dot in the periphery. We found that emotional distractors impaired target recognition performance to comparable extents, regardless of whether or not participants concurrently performed the peripheral-monitoring task. Moreover, we found that performance of the secondary task led to an impaired ability to ignore neutral distractors. Subjective ratings of target vividness mirrored the behavioral accuracy, with frequent reports of intermediate levels of vividness suggesting that the EAB might impair target visibility in a graded manner. Our results demonstrate that the EAB is robust to manipulations of top-down attention, suggesting that the temporary capture of attention by emotionally salient stimuli involves processes that are distinct from those that produce the attentional blink. PMID- 30291555 TI - Validation d'un questionnaire auto-administre sur les valeurs en politique publique de sante. AB - OBJECTIVES: The aims of this article are to describe the development of a self administered questionnaire assessing the core values in the field of public health ( radardesvaleurs.com ) and to report the results of a study testing the questionnaire's test-retest reliability, internal consistency and construct validity. METHOD: A 24-item questionnaire grounded in the conceptual framework of Shalom H. Schwartz (2000) was developed by a group of international experts in public health. Six scores were generated, each linked to a specific value and put on three axes: individualism-equity, autonomy-conformity and risk-security. The questionnaire was submitted to students attending the School of Public Health of the Universite de Montreal (ESPUM) (n = 700). A total of 401 students completed the questionnaire, 52 of whom completed it again one month later. RESULTS: For the test-retest reliability, all percentages of agreement were equal or superior to 60% except for a single question (50%). All Cohen's kappa coefficients of individual items were strong (> 0.60) except for three questions which presented a very high percentage of agreement. The Intraclass Correlation coefficients of the values' scores varied between 0.27 and 0.77. The three axes' internal consistency was estimated by Cronbach's alphas (between 0.46 and 0.74). The exploratory factorial analysis only partially confirmed the questionnaire's theoretical structure. CONCLUSION: Despite the limits of the results, the questionnaire has an interesting level of reliability and validity, which makes its pedagogical use pertinent to pursue. The limitation to four items/value, as well as the representativeness of the sampling (ESPUM students), could explain certain empirical shortcomings of the questionnaire. PMID- 30291554 TI - Episodic Migraine With and Without Aura: Key Differences and Implications for Pathophysiology, Management, and Assessing Risks. AB - PURPOSE OF REVIEW: To review the pathophysiologic, epidemiologic, and clinical evidence for similarities and differences between migraine with and without aura. RECENT FINDINGS: The ICHD-3 has recently refined the diagnostic criteria for aura to include positive symptomatology, which better differentiates aura from TIA. Although substantial evidence supports cortical spreading depression as the cause of visual aura, the role (if any) of CSD in headache pain is not well understood. Recent imaging evidence suggests a possible hypothalamic origin for a headache attack, but further research is needed. Migraine with aura is associated with a modest increase in the risk of ischemic stroke. The etiology for this association remains unclear. There is a paucity of evidence regarding treatments specifically aimed at the migraine with aura subtype, or whether migraine with vs without aura responds to treatment differently. Migraine with typical aura is therefore often treated similarly to migraine without aura. Lamotrigine, daily aspirin, and flunarizine have evidence for efficacy in prevention of migraine with aura, and magnesium, ketamine, furosemide, and single-pulse transcranial magnetic stimulation have evidence for use as acute treatments. Although triptans have traditionally been contraindicated in hemiplegic migraine and migraine with brainstem aura, this prohibition is being reconsidered in the face of evidence suggesting that use may be safe. The debate as to whether migraine with and without aura are different entities is ongoing. In an era of sophisticated imaging, genetic advancement, and ongoing clinical trials, efforts to answer this question are likely to yield important and clinically meaningful results. PMID- 30291556 TI - Initial Benchmarking of the Liquid Sampling-Atmospheric Pressure Glow Discharge Orbitrap System Against Traditional Atomic Mass Spectrometry Techniques for Nuclear Applications. AB - The integration of the liquid sampling-atmospheric pressure glow discharge (LS APGD) ion source with Orbitrap mass spectrometers has resulted in new opportunities in the field of isotope ratio mass spectrometry. In a field that has been dominated by thermal ionization mass spectrometry (TIMS) and inductively coupled plasma mass spectrometry (ICP-MS) on quadrupole and scanning-mode sector field analyzer platforms for highly accurate and precise measurements, the LS APGD-Orbitrap system offers a benchtop instrument capable of meeting the rigorous International Target Values for measurement uncertainty for uranium (U). In order to benchmark the LS-APGD-Orbitrap, a series of U certified reference materials with increasing 235U isotopic composition were analyzed. By using U samples ranging in enrichment from 1 to 80%, the ability of the system to measure isotope ratios over a wide range is demonstrated. This analysis represents the first time that the LS-APGD-Orbitrap system has been used to analyze highly enriched U samples, allowing for the measurement of each of the U isotopes, including 234U and 236U-related species, which had not been achieved previously. Ultimately, the LS-APGD-Orbitrap system was able to measure CRM U-800 (assayed as 235U / 238U = 4.265622) as 4.266922, with a combined uncertainty, (uc), of 0.040%. These results are compared to those obtained using traditional elemental mass spectrometers including TIMS and ICP-MS-based instruments. The effectiveness of the LS-APGD-Orbitrap MS system for measuring U isotopes shows excellent promise in nuclear forensics, safeguards, and other nuclear weapon-based applications. Graphical Abstract ?. PMID- 30291557 TI - Cytomegalovirus meningitis in a patient with relapsed acute myeloid leukemia. AB - Cytomegalovirus meningitis/meningoencephalitis is a potentially fatal complication following hematopoietic stem cell transplantation that causes significant morbidity and mortality. In the pre-transplant setting, a few cases involving lymphoid malignancies have been reported. However, there have been no reports of patients with myeloid malignancies. A 36-year-old man with relapsed acute myeloid leukemia received high-dose cytarabine-containing salvage chemotherapies and then developed grade 4 lymphopenia for more than one month. Subsequently, the patient developed pyrexia, accompanying headache, nausea, and vomiting with no abnormal brain imaging. Despite receiving antimicrobial treatment, his febrile status and headache persisted. Given that the patient had symptoms consistent with viral meningitis with no evidence of etiology other than positive cytomegalovirus-DNA in his cerebrospinal fluid and cytomegalovirus pp65 antigenemia, cytomegalovirus meningitis was diagnosed. After commencing ganciclovir treatment, the patient's headache and febrile status rapidly improved. Cytomegalovirus meningitis/meningoencephalitis is rare before hematopoietic stem cell transplantation, but may be useful in differential diagnoses in heavily treated acute myeloid leukemia patients with central nervous system symptoms. PMID- 30291558 TI - Venous thromboembolism in relapsed or refractory multiple myeloma patients treated with lenalidomide plus dexamethasone. AB - Lenalidomide plus dexamethasone (LD) is currently the mainstay of treatment for both untreated and relapsed or refractory multiple myeloma (RRMM). Although lenalidomide-associated venous thromboembolism (VTE) is a major clinical concern, its incidence and prognostic impact have not been delineated. In this nationwide retrospective cohort study, we aimed to determine the cumulative incidence of VTE and its prognostic value using two consecutive cohorts of LD-treated RRMM patients: the KMM151 cohort (N = 542) and the HIRA cohort (N = 1559). Data were collected from medical records for the KMM151 cohort and healthcare insurance claims database for the HIRA cohort. Throughout the study period, 24 patients (4.4%) in the KMM151 cohort and 80 patients (5.1%) in the HIRA cohort developed VTE. The cumulative incidence reached a plateau approximately 2 years after LD initiation. The 2-year incidence was 4.9% in the KMM151 cohort and 8% in the HIRA cohort. Higher starting dose of lenalidomide, previous history of VTE, and older age were associated significantly with an increased VTE risk. Early-onset VTE was associated significantly with poor survival. In conclusion, VTE occurred in 5-8% of RRMM patients treated with LD over 2 years, and early-onset VTE was a strong indicator of poor prognosis. PMID- 30291559 TI - Implementation of day of surgery admission for rectal cancer surgery in Ireland following a national centralisation programme. AB - BACKGROUND: Centralisation of rectal cancer surgery has altered the delivery of colorectal cancer care in Ireland. This has resulted in an increased demand for elective surgical beds in designated centres. AIM: This study aimed to assess if day of surgery admission (DOSA), in conjunction with implementation of a coordinated enhanced recovery pathway can reduce length of stay following elective rectal cancer resection. METHODS: This is a retrospective review from a single institution. Our prospectively maintained Dendrite(r) Database was interrogated. Three time points were analysed across a 7-year period (2011, 2012, 2016). The first predates the introduction of a dedicated DOSA programme, the next was directly thereafter, and the final was 5-years post-implementation. These dates coincide with the centralisation of rectal cancer surgery to this centre. Outcomes included unadjusted length of stay and rates of DOSA pre-and post-implementation of the programme. RESULTS: The introduction of a DOSA pathway resulted in a fivefold increase in day of surgery admissions and a related 3-day reduction in average length of stay within a single year of implementation. This further improved in 2016, showing an almost 83% increase (15.90-98.50%) in day of surgery admission and a reduction in average length of stay from 16.4 to 12.4 days when compared to 2011. CONCLUSIONS: Despite an increase in caseload of 54%, an estimated 272 bed days were saved. This demonstrated that DOSA is sustainable and highly effective in tackling the increased inpatient bed demands associated with the growing requirement for elective surgery. PMID- 30291560 TI - Inflammation as a Regulator of the Renin-Angiotensin System and Blood Pressure. AB - PURPOSE OF REVIEW: Mechanisms facilitating progression of hypertension via cross stimulation of the renin-angiotensin system (RAS) and inflammation have been proposed. Accordingly, we review and update evidence for regulation of RAS components by pro-inflammatory factors. RECENT FINDINGS: Angiotensin II (Ang II), which is produced by RAS, induces vasoconstriction and consequent blood pressure elevation. In addition to this direct action, chronically elevated Ang II stimulates several pathophysiological mechanisms including generation of oxidative stress, stimulation of the nervous system, alterations in renal hemodynamics, and activation of the immune system. In particular, an activated immune system has been shown to contribute to the development of hypertension. Recent studies have demonstrated that immune cell-derived pro-inflammatory cytokines regulate RAS components, further accelerating systemic and local Ang II formation. Specifically, regulation of angiotensinogen (AGT) production by pro inflammatory cytokines in the liver and kidney is proposed as a key mechanism underlying the progression of Ang II-dependent hypertension. PMID- 30291561 TI - Quality of diabetes care in breast, colorectal, and prostate cancer. AB - PURPOSE: Overlooking other medical conditions during cancer treatment and follow up could result in excess morbidity and mortality, thereby undermining gains associated with early detection and improved treatment of cancer. We compared the quality of care for diabetes patients subsequently diagnosed with breast, colorectal, or prostate cancer to matched, diabetic non-cancer controls. METHODS: Longitudinal cohort study using primary care records from the Clinical Practice Research Datalink, United Kingdom. Patients with pre-existing diabetes were followed for up to 5 years after cancer diagnosis, or after an assigned index date (non-cancer controls). Quality of diabetes care was estimated based on Quality and Outcomes Framework indicators. Mixed effects logistic regression analyses were used to compare the unadjusted and adjusted odds of meeting quality measures between cancer patients and controls, overall and stratified by type of cancer. RESULTS: 3382 cancer patients and 11,135 controls contributed 44,507 person-years of follow-up. In adjusted analyses, cancer patients were less likely to meet five of 14 quality measures, including: total cholesterol <= 5 mmol/L (odds ratio [OR] = 0.82; 95% confidence interval [CI], 0.75-0.90); glycosylated hemoglobin <= 59 mmol/mol (adjusted OR = 0.77; 95% CI, 0.70-0.85); and albumin creatinine ratio testing (adjusted OR = 0.83; 95% CI, 0.75-0.91). However, cancer patients were as likely as their matched controls to meet quality measures for other diabetes services, including retinal screening, foot examination, and dietary review. CONCLUSIONS: Although in the short-term, cancer patients were less likely to achieve target thresholds for cholesterol and HbA1c, they continued to receive high-quality diabetes primary care throughout 5 years post diagnosis. IMPLICATIONS FOR CANCER SURVIVORS: These findings are important for cancer survivors with pre-existing diabetes because they indicate that high quality diabetes care is maintained throughout the continuum of cancer diagnosis, treatment, and follow-up. PMID- 30291563 TI - Rapidly progressive encephalopathy caused by Coxsackie meningoencephalitis in an elderly male. AB - Enteroviruses and Coxsackie viruses are common causes of aseptic meningitis and encephalitis in children. These infections usually have a benign, self-limited course. However, they can have a florid presentation in immunocompromised patients, such as neonates, patients exposed to immunosuppressive drugs, such as transplant recipients and patients with agammaglobulinemia. We present a rare case of rapidly progressive acute encephalopathy caused by Coxsackie meningoencephalitis and complicated by refractory status epilepticus in an immunocompetent adult male. Our case highlights the importance of having a broad differential in patients presenting with rapidly progressive acute encephalopathy. Although rare, an enterovirus infection caused by a Coxsackie virus subtype can have a severe presentation causing significant morbidity. This case, also underscores the importance of searching for underlying immunodeficiency in malignant presentations of common viral infections. Hence, rapidly progressive acute encephalopathy due to coxsackievirus can occur in immunocompetent individuals. Aggressive and systematic diagnostic and therapeutic approach in such severe cases can influence overall outcomes. PMID- 30291564 TI - Genetic characterization of measles virus genotype D6 subacute sclerosing panencephalitis case, Alberta, Canada. AB - Subacute sclerosing panencephalitis (SSPE) is a progressive and eventually fatal neurological disease arising from a persistent infection with measles virus (MV) acquired at a young age. SSPE measles virus strains are defective and unable to produce progeny virions, due to multiple and extensive mutations in a number of key genes. We sequenced the full MV genome from our recently reported SSPE case, which typed as genotype D6, and compared it with other genotype D6 wild type and SSPE sequences. The Alberta D6 strain was significantly different from other reported SSPE D6 sequences. Mutations were observed in all the genes of the Alberta strain, with the greatest sequence divergence noted in the M gene with 17.6% nucleotide and 31% amino acid variation. The L gene showed the least variation with 1.3% nucleotide and 0.7% amino acid differences respectively. The nucleotide variability for 15,672 bases of the complete genome compared to the wild type and other SSPE D6 strains was around 3%.

Although experimental triggers such as glyceryl trinitrate reliably produce migraine, natural triggers are much less predictable and vary in importance between individuals. This review describes the most common triggers in episodic migraine and provides strategies for managing them in clinical practice. RECENT FINDINGS: Multiple migraine attack triggers have been established based on patient surveys, diary studies, and clinical trials. Stress, menstrual cycle changes, weather changes, sleep disturbances, alcohol, and other foods are among the most common factors mentioned. Clinical studies have verified that fasting, premenstrual periods in women, "letdown" after stress, and most likely low barometric pressures are migraine triggers. Premonitory symptoms such as neck pain, fatigue, and sensitivity to lights, sounds, or odors may mimic triggers. Multiple studies clearly demonstrate triggers in episodic migraine, often related to change in homeostasis or environment. Many common migraine triggers are not easily modifiable, and avoiding triggers may not be realistic. Healthy lifestyle choices such as exercise, adequate sleep, stress management, and eating regularly may prevent triggers and transformation to chronic migraine over time. PMID- 30291565 TI - Mechanisms of neuropathogenesis in HIV and HCV: similarities, differences, and unknowns. AB - HIV and hepatitis C virus (HCV) have both been associated with cognitive impairment. Combination antiretroviral therapy (cART) has dramatically changed the nature of cognitive impairment in HIV-infected persons, while the role of direct-acting antivirals (DAA) in neurocognition of HCV-infected individuals remains unclear. Also, whether HIV and HCV interact to promote neurocognitive decline or whether they each contribute an individual effect continues to be an open question. In this work, we review the virally mediated mechanisms of HIV- and HCV-mediated neuropathogenesis, with an emphasis on the role of dual infection, and discuss observed changes with HIV viral suppression and HCV functional cure on neurocognitive impairments. PMID- 30291566 TI - Incomplete myelopathy and human T cell lymphotropic virus type-1 (HTLV-1). AB - This was a cross-sectional prospective study. We performed a multivariate statistical analysis of the neurological signs and symptoms of patients infected with human T cell lymphotropic virus type 1 (HTLV-1) in an attempt to separate them into distinct groups and identify clinical-neurological manifestations that could differentiate the various profiles. The study was performed in the city of Belem (state of Para), located in the Amazon region of Brazil, from 2014 to 2016. We determined muscle strength and tone, reflexes, sensations, sphincter function, gait, and the Expanded Disability Status Scale score among individuals with HTLV I. We then used exploratory statistical methods in an attempt to find different profiles and establish distinct groups. We analyzed 60 patients with HTLV-1. The filtering of the data, performed with mixed PCA, gave rise to a streamlined database with the most informative data and suggested the formation of three statistically distinct groups: asymptomatic carriers (AC), mono/oligosymptomatic (MOS), and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSPd), AC and MOS (p = 0.002), AC and HAM/TSPd (p < 0.001), and HAM/TSPd and MOS (p = 0.001). The subsequent cluster analysis confirmed the formation of three clusters. The classification and regression tree demonstrated that altered gait was the most important variable for the classification of an individual with HAM/TSPd and that, in the absence of this impairment, hyperreflexia characterized MOS. The present study was able to separate patients infected by HTLV-1 into three clinical groups (AC, HAM/TSPd, and MOS) and identify clinical manifestations that could differentiate the various patient groups. PMID- 30291568 TI - Comparison of oral flora before and after triple therapy for Helicobacter pylori eradication in patient with gastric disease. AB - The oral cavity is recognized as a major route for infection by Helicobacter pylori, which colonizes the gastric mucosa. Therapeutic options for elimination in patients with digestive disease have been established, though whether antibiotics are effective for H. pylori harbored in the oral cavity as well as oral commensal bacteria remain unknown. A 29-year-old woman visited a gastrointestinal clinic with a chief complaint of stomach ache. Gastroscopy and urine test findings for H. pylori IgG led to a definitive diagnosis of goose bumps gastritis induced by bacteria in the stomach, and triple therapy for H. pylori eradication was administered. Oral samples were obtained 10 times at a dental hospital clinic from 1 week before until 6 months after starting triple therapy. Nested PCR amplifying the ureA gene and PCR assays using species specific primer sets were performed to detect H. pylori and major oral commensal bacterial species, respectively, in those samples. Bacterial DNA encoding the ureA gene of H. pylori in oral specimens was detected prior to starting therapy, which was then reduced during and not detected after finishing treatment. Although the populations of major oral pathogenic bacteria, such as periodontopathic and oral streptococcal species, were drastically reduced during triple therapy, most had recovered within approximately 1 week after ending treatment. These results suggest that a conventional triple therapy approach for eradication of H. pylori in cases of digestive disease is effective for elimination of the bacterium from the oral cavity. On the other hand, after finishing such therapy, the oral flora composition is not drastically changed. PMID- 30291567 TI - White matter damage, neuroinflammation, and neuronal integrity in HAND. AB - HIV-associated neurocognitive disorders (HANDs) persist even with virologic suppression on combination antiretroviral therapy (cART), and the underlying pathophysiological mechanisms are not well understood. We performed structural magnetic resonance imaging and MR spectroscopy (MRS) in HIV+ individuals without major neurocognitive comorbidities. Study participants were classified as neurocognitively unimpaired (NU), asymptomatic (ANI), mild neurocognitive disorder (MND), or HIV-associated dementia (HAD). Using structural MRI, we measured volumes of cortical and subcortical gray matter and total and abnormal white matter (aWM). Using single-voxel MRS, we estimated metabolites in frontal gray matter (FGM) and frontal white matter (FWM) and basal ganglia (BG) regions. Adjusted odds ratios were used to compare HAND to NU. Among 253 participants, 40% met HAND criteria (21% ANI, 15% MND, and 4% HAD). Higher risk of HAND was associated with more aWM. Both HAD and MND also had smaller gray and white matter volumes than NU. Among individuals with undetectable plasma HIV RNA, structural volumetric findings were similar to the overall sample. MND had lower FWM creatine and higher FGM choline relative to NU, whereas HAD and ANI had lower BG N-acetyl aspartate relative to NU. In the virologically suppressed subgroup, however, ANI and MND had higher FGM choline compared to NU. Overall, HAND showed specific alterations (more aWM and inflammation; less gray matter volume and lower NAA). Some MR measures differentiated less severe subtypes of HAND from HAD. These MR alterations may represent legacy effects or accumulating changes, possibly related to medical comorbidities, antiretroviral therapy, or chronic effects of HIV brain infection. PMID- 30291569 TI - Rhesus Macaque Brain Atlas Regions Aligned to an MRI Template. AB - To aid in the analysis of rhesus macaque brain images, we aligned digitized anatomical regions from the widely used atlas of Paxinos et al. to a published magnetic resonance imaging (MRI) template based on a large number of subjects. Digitally labelled atlas images were aligned to the template in 2D and then in 3D. The resulting grey matter regions appear qualitatively to be well registered to the template. To quantitatively validate the procedure, MR brain images of 20 rhesus macaques were aligned to the template along with regions drawn by hand in striatal and cortical areas in each subject's MRI. There was good geometric overlap between the hand drawn regions and the template regions. Positron emission tomography (PET) images of the same subjects showing uptake of a dopamine D2 receptor ligand were aligned to the template space, and good agreement was found between tracer binding measures calculated using the hand drawn and template regions. In conclusion, an anatomically defined set of rhesus macaque brain regions has been aligned to an MRI template and has been validated for analysis of PET imaging in a subset of striatal and cortical areas. The entire set of over 200 regions is publicly available at https://www.nitrc.org/ . Graphical Abstract ?. PMID- 30291570 TI - Estimation of annual effective dose due to ingestion of radioactive elements in Sri Lankan common meal plans. AB - Dietary ingestion of radionuclides by human may lead to many hazardous effects such as cancers. No studies have been conducted to estimate the levels of radioactivity dosage received from Sri Lankan homemade foods. In order to find out the levels of radionuclides in Sri Lankan cooked foods, meal plans (n = 11) that are most commonly consumed were analyzed for the activity concentrations of the radioisotopes 226Ra, 210Pb, 232Th, 137Cs, and 40K by means of gamma spectroscopy. 40K had the highest activity concentration present in the meal plans with a range of 80.56 +/- 17.53 to 143.41 +/- 24.6 Bq kg-1, and the radionuclides 226Ra, 210Pb, 137Cs, and 232Th were not detected in any of the analyzed meal plans. The annual intake of food was determined on the basis of their average annual consumption. The effective dose to an average adult who consumes the meal plans ranged from 0.030 to 0.051 mSv year-1. However, the effective dose and activity concentrations of radionuclides were lower than the guideline limit specified by United Nations Scientific Committee on the Effects of Atomic Radiation-1 and other countries. Hence, the consumption of cooked meal plans in Sri Lanka is safe in terms of radioactivity for the five radionuclides investigated in this study. PMID- 30291571 TI - Buprenorphine for Chronic Pain: a Systemic Review. AB - PURPOSE OF REVIEW: The purpose of this review is to evaluate and explain our current understanding of the clinical use of buprenorphine in the treatment of chronic pain. RECENT FINDINGS: There has been few high-quality, unbiased studies performed on the use of buprenorphine in the treatment of chronic pain. Buprenorphine is an effective and safe analgesic that is tolerated at least as well, if not better, than other opioids. Given its safety and mechanistic advantages, the authors believe there is an important role for buprenorphine in the treatment of chronic pain severe enough to warrant the use of an opioid analgesic. Though data is lacking for superiority in chronic pain states, the other advantages of the molecule make it the preferential first-line opioid for around-the-clock pain in our practice. PMID- 30291572 TI - What Are We Missing in the Diagnostic Criteria for Migraine? AB - PURPOSE OF REVIEW: This review is intended to examine how the diagnostic criteria for migraine have evolved over the past 45 years and to evaluate the strengths and weaknesses of the current diagnostic criteria promulgated by the International Classification of Headache Disorders (ICHD). RECENT FINDINGS: The ICHD is a comprehensive and systematic classification system for headache disorders. As the pathophysiology of migraine is more fully elucidated and more sophisticated diagnostic technologies are developed (e.g., the identification of biomarkers), the current diagnostic criteria for migraine will likely be further refined. The ICHD has allowed for more precise research study design in the field of headache medicine. The current diagnostic criteria for migraine outlined in the 3rd version of the ICHD are far more sensitive and specific than the clinical criteria proposed in 1962. In future iterations, dividing episodic and chronic migraine into subtypes based on frequency (i.e., low frequency vs high frequency; near-daily vs daily) potentially could assist in guiding clinical management. In addition, a better understanding of aura, vestibular migraine, migrainous infarction, and hemiplegic migraine likely will lead to more refined diagnostic criteria for those entities. PMID- 30291573 TI - Corticosteroid Receptors in the Brain: Transcriptional Mechanisms for Specificity and Context-Dependent Effects. AB - Corticosteroid hormones act in the brain to support adaptation to stress via binding to mineralocorticoid and glucocorticoid receptors (MR and GR). These receptors act in large measure as transcription factors. Corticosteroid effects can be highly divergent, depending on the receptor type, but also on brain region, cell type, and physiological context. These differences ultimately depend on differential interactions of MR and GR with other proteins, which determine ligand binding, nuclear translocation, and transcriptional activities. In this review, we discuss established and potential mechanisms that confer receptor and cell type-specific effects of the MR and GR-mediated transcriptional effects in the brain. PMID- 30291574 TI - Virtual touch IQ elastography in evaluation of Achilles tendon in patients with chronic renal failure. AB - PURPOSE: To evaluate the sonoelastographic changes in the Achilles tendon in patients with chronic renal failure (CRF) using virtual touch imaging quantification (VTIQ) elastography. METHODS: Twenty-six patients undergoing three hemodialysis sessions per week and 26 subjects admitted to our institution between January 2016 and April 2016 were included in this prospective study. The characteristics and body mass index of the patients were noted. Ultrasonography was performed parallel to the long axis of the bilateral Achilles tendons during relaxation of the legs using the Siemens Acuson S3000TM ultrasound device (Siemens HealthCare, Erlangen, Germany). Tendon thickness was reviewed, and tissue stiffness was quantitatively assessed using VTIQ elastography. Independent samples t test and Mann-Whitney U test were used for statistical analyses. RESULTS: The median values of shear wave velocities of the Achilles tendon in patients with CRF were 7.19 m/s (4.23-9.77 m/s) on the right and 6.98 m/s (4.00 9.82 m/s) on the left, while they were 5.11 m/s (4.09-8.82 m/s) on the right and 5.36 m/s (4.05-8.80 m/s) on the left in controls. The stiffness of the Achilles tendons in patients with CRF was found to be higher than that in controls (right: P < 0.001, left: P = 0.004). There was no statistically significant difference in tendon thickness between the CRF and control groups (P > 0.05). CONCLUSION: The thickness and stiffness of tendon can be effectively evaluated with sonoelastography. The thickness of the Achilles tendon did not significantly differ between the patients with CRF and healthy subjects. However, the stiffness of the Achilles tendon measured with VTIQ elastography was demonstrated to be increased in the patients with CRF. PMID- 30291575 TI - Three-dimensional sonographic minute structure analysis of fetal cerebellar vermis development and malformations: utilizing volume contrast imaging. AB - PURPOSE: To obtain three-dimensional ultrasonic (3D US) structural details and biometrics of the fetal cerebellar vermis and evaluate the value of developmental and malformation identification. METHODS: The 3D US minute structure of the fetal cerebellar vermis in mid-sagittal view was detected in normal fetuses (n = 438; 16-41 weeks). Biometric sizes were measured to establish the stage-specific norms and reproducibility analysis. Additionally, 28 fetuses with suspected abnormal posterior fossa contents were assessed to analyze the clinical value. RESULTS: The minute structure of normal fetuses, including cerebellar vermis contours and the fastigial recess of the fourth ventricle, were visible around Week 19. The main lobules and fissures were apparent around Week 22, and all nine lobules, fissures, and the fourth ventricle were clearly displayed by Week 28. Cerebellar vermis biometric sizes (anterior-posterior length, cranio-caudal length, circumference, and surface area (SA)) grew in a linear fashion with high reliability, especially SA measurements (for intraclass, ICC 0.989, 95% CI (0.980 0.994); for interclass, ICC 0.992, 95% CI (0.984-0.996)). On the middle sagittal section of 3D US, the SA reduced at least 50% in the Dandy-Walker group with no recognizable cerebellar vermis structures showing. The SA in vermian hypoplasia malformation reduced during [Formula: see text] to 50% with the primary/secondary fissures absent or partly absent and arborization of the lobules reduced. That would be an important diagnosis and antidiastole clue. Combined with minute structural observation, sonographic diagnoses were accurate in 88% of cases. CONCLUSION: Minute structures obtained by 3D US were clinically useful in the evaluation of cerebellar vermis development and cerebellar vermis malformations. PMID- 30291576 TI - Contrasted evolutionary constraints on carbohydrate active enzymes (CAZymes) in selected Frankia strains. AB - Carbohydrate active enzymes (CAZymes) are capable of breaking complex polysaccharides into simpler form. In plant-host-associated microorganisms CAZymes are known to be involved in plant cell wall degradation. However, the biology and evolution of Frankia CAZymes are largely unknown. In the present study, we took a genomic approach to evaluate the presence and putative roles of CAZymes in Frankia. The CAZymes were found to be potentially highly expressed (PHX) proteins and contained more aromatic amino acids, which increased their biosynthetic energy cost. These energy rich amino acids were present in the active sites of CAZymes aiding in their carbohydrate binding capacity. Phylogenetic and evolutionary analyses showed that, in Frankia strains with the capacity to nodulate host plants, CAZymes were evolving slower than the other PHX genes, whereas similar genes from non-nodulating (or ineffectively nodulating) Frankia strains showed little variation in their evolutionary constraints compared to other PHX genes. Thus, the present study revealed the persistence of a strong purifying selection on CAZymes of Frankia indicating their crucial role. PMID- 30291577 TI - Medication-related problems during transfer from hospital to home care: baseline data from Switzerland. AB - Background The shift from inpatient to ambulatory care has resulted in an increase in home care patients. Little is known regarding medication safety associated with patient transfer from hospital to home care. Objective To evaluate medication-related problems in patients transferring from hospital to home care in Switzerland. Setting A non-for-profit home care organization in the city of Lucerne/Switzerland. Methods We conducted a prospective observational study, including patients aged >= 64 years and receiving >= 4 medications at hospital discharge. Two structured questionnaires assessing the transfer process were completed by home care nurses. Prescription quality was assessed using a PCNE Type 2b Medication Review. Main outcome measures The quality of the transfer process was measured comparing agreed-upon with reported parameters. Prescription quality was analyzed assessing the unambiguity of the prescription. Potentially inappropriate medications (Priscus(r) list), contraindications, duplications and interactions, and clinical pharmacist-identified potential medication-related problems were collected. Results Study patients (n = 100) received 8.6 +/- 3.5 regularly administered medications. Only 5/100 patients had a complete set of written discharge information. At the time of the first visit, 13/100 patients had no written medication information available. Discharge medication prescriptions were clear to nurses in 62% of patients. In 20 patients, the required medications were unavailable, resulting in 19 medication errors. Assessment by a clinical pharmacist revealed only 33/100 patients had a clear discharge prescription. Of a total of 984 prescribed drugs, 16% were considered to be ambiguous, 22 (2.2%) were potentially inappropriate. 7/984 drugs were contraindicated, 8 were duplicates. Conclusion In addition to the known risk factors in patients transferring from hospital to home care (age, polymedication, multiple providers), 3 major problems impacted upon medication safety: fragmented communication, unreliable medication availability and a poor prescription quality. Clinical pharmacists are an important option to improve medication safety ass. PMID- 30291578 TI - Nutritional epidemiology and cancer: A Tale of Two Cities. AB - Recently, Ioannidis questioned whether nutritional epidemiology could be reconciled with good scientific principles, and suggested that the field needs radical reform. One of the reforms he advocated was more randomized trials; though what diet would be tested and how it would be measured were unspecified, how adherence would be monitored was unclear or unimportant, and the length of time vaguely stated as "lifelong". The other reform was reanalysis of shared data, which actually already exists in a large number of cohort consortia of individual pooled data. The 2018 report analysis of diet and cancer from the World Cancer Fund/American Institute of Cancer Research presents a sharply different picture of our knowledge of nutrition and cancer, which has evolved immensely in the past 3 decades. Based on current knowledge, factors related to energy balance, encompassed by body mass anthropometric measures might account for about 10-15% of the U.S. cancer burden. This 10-15% encompasses physical activity and obesogenic effects of diet. About 5% may be attributable to alcohol, and another 5% to specific dietary factors combined (e.g., red and processed meat, whole grains, fiber, calcium, fruits, and vegetables). Surrogates such as attained height and age at menarche are influenced by nutrition and are consistent risk factors for cancer, supporting the importance of early nutrition. Recent data suggest that early life dietary patterns, which may be modifiable, may be important. Though important questions remain, our understanding of nutrition and cancer over the life course is coherent and has been informed by nutritional epidemiology and other data. PMID- 30291579 TI - A Stepwise Approach in Learning Surgical Residents a Roux-en-Y Gastric Bypass. AB - INTRODUCTION: This study describes a stepwise training program to teach a laparoscopic Roux-en-Y gastric bypass (LRYGB). Results of a resident are compared to experienced bariatric surgeons (EBS). METHODS: The resident performed a varying amount of surgical steps and the duration of every step was measured using video analysis. In order to compare the resident's results to EBS, the average time per step was calculated for 30 procedures. RESULTS: The total procedure time of LRYGB was 61.15 (+/- 8.74) min for a novice resident. In comparison, the average of three EBS was 36.22 (+/- 9.06) min. Creation of the gastric pouch had an average of 12.82 (+/- 4.08) versus 6.93 (+/- 2.58) min. Duration of creating the stapled gastrojejunostomy was 7.43 (+/- 2.11) versus 4.48 (+/- 2.02) min. Suturing of the gastrojejunostomy was 12.60 (+/- 3.31) compared to 6.31 (+/- 2.53) min. Creating the jejunojejunal anastomosis had a duration of 7.12 ( +/-2.31) versus 4.22 (+/- 1.60) min and suturing this anastomosis was 13.93 (+/- 3.81) compared to 8.51 (+/- 3.37) min. At the end of the traineeship, the observed progression approximated the skills level of the EBS. CONCLUSION: The stepwise LRYGB-training program, analysed in this study, can result in an efficient and safe way to approach the learning curve to the level of the EBS. Within this training program, the total time of the operation is kept low in order to prevent adverse events for the patient and loss of efficiency in the bariatric program. The results of this study could act as a guideline for the development of such training programs. PMID- 30291580 TI - Baseline Pro-inflammatory Diet Is Inversely Associated with Change in Weight and Body Fat 6 Months Following-up to Bariatric Surgery. AB - OBJECTIVE: To evaluate whether the baseline Dietary Inflammatory Index (DII(r)) was associated with weight loss and body composition change after bariatric surgery. METHODOLOGY: This longitudinal study included 132 women with obesity (BMI >= 35 kg/m2, 43.0 +/- 9.7 years), followed up for 6 months after bariatric surgery. The DII(r) was calculated from dietary data collected using 24-h dietary recall interviews. Anthropometric variables, socio demographic variables, health related habits, history of disease, as well as gastrointestinal symptoms, both in the preoperative period (baseline) and 6 months after bariatric surgery were collected from the patients' medical records. RESULTS: Individuals with a more pro-inflammatory diet (DII > 0.35 median value) preoperatively experienced smaller weight loss (- 22.7% vs. - 25.3%, p = 0.02) and fat mass loss (- 31.9 vs. - 36.2%, p = 0.026), with no difference in lean mass (p = 0.14). In a linear regression model, the baseline DII score was negatively associated with percentage change in weight and fat mass and positively associated with weight and fat mass in the sixth month after surgery. In addition, a pro-inflammatory baseline DII score was correlated with a lower intake of fruit (r = - 0.26, p = 0.006), vegetables (r = - 0.47, p = 0.001), and legumes (r = - 0.21, p = 0.003) in the postoperative period. CONCLUSION: In this longitudinal study, a pro inflammatory diet at baseline was associated with smaller reductions in weight and body fat and poorer dietary quality (reduced consumption of fruits, vegetables, and legumes) 6 months after bariatric surgery. PMID- 30291581 TI - Citrate analysis using capillary electrophoresis and complexation with Eu3+ tetracycline. AB - A sensitive assay for citrate was developed. Citrate was incubated with 50 MUM Eu3+-tetracycline and the complex separated using capillary electrophoresis utilizing post-column laser-induced luminescence detection in a sheath flow cuvette. Signal was linear with citrate concentration from 10 MUM to 200 nM. Injection volumes were 320 pL. For the 200 nM sample, this corresponds to the injection of 64 amoles of citrate. Separation time was < 90 s with a total run time of 5 min. As an application the method was used to analyze citrate in agricultural and medicinal products. The method was also used to develop an assay for the enzyme citrate synthase. PMID- 30291582 TI - Ictal Source Locations and Cortico-Thalamic Connectivity in Childhood Absence Epilepsy: Associations with Treatment Response. AB - Childhood absence epilepsy (CAE), the most common pediatric epilepsy syndrome, is usually treated with valproic acid (VPA) and lamotrigine (LTG) in China. This study aimed to investigate the ictal source locations and functional connectivity (FC) networks between the cortices and thalamus that are related to treatment response. Magnetoencephalography (MEG) data from 25 patients with CAE were recorded at 300 Hz and analyzed in 1-30 Hz frequency bands. Neuromagnetic sources were volumetrically scanned with accumulated source imaging. The FC networks between the cortices and thalamus were evaluated at the source level through a connectivity analysis. Treatment outcome was assessed after 36-66 months following MEG recording. The children with CAE were divided into LTG responder, LTG non-responder, VPA responder and VPA non-responder groups. The ictal source locations and cortico-thalamic FC networks were compared to the treatment response. The ictal source locations in the post-dorsal medial frontal cortex (post-DMFC, including the medial primary motor cortex and the supplementary sensorimotor area) were observed in all LTG non-responders but in all LTG responders. At 1-7 Hz, patients with fronto-thalamo-parietal/occipital (F-T-P/O) networks were older than those with fronto-thalamic (F-T) networks or other cortico-thalamic networks (p = 0.000). The duration of seizures in patients with F-T-P/O networks at 1-7 Hz was longer than that in patients with F-T networks or other cortico-thalamic networks (p = 0.001). The ictal post-DMFC source localizations suggest that children with CAE might experience initial LTG monotherapy failure. Moreover, the cortico-thalamo-cortical network is associated with age. Finally, the cortico-thalamo-cortical network consists of anterior and posterior cortices and might contribute to the maintenance of discharges. PMID- 30291583 TI - Effects of Neutralizing Antibody Production on AAV-PHP.B-Mediated Transduction of the Mouse Central Nervous System. AB - Adeno-associated virus (AAV)-PHP.B, a capsid variant of AAV serotype 9, is highly permeable to the blood-brain barrier. A major obstacle to the systemic use of AAV PHP.B is the generation of neutralizing antibodies (NAbs); however, temporal profiles of NAb production after exposure to AAV-PHP.B, and the influence on later AAV-PHP.B administration, remains unknown. To address these, AAV-PHP.Bs expressing either GFP or mCherry by neuron-specific or astrocyte-specific promoters were intravenously administered to mice at various intervals, and brain expression was examined. Injection of two AAV-PHP.Bs, separated temporally, showed that as little as a 1-day interval between injections resulted in a significant decrease in expression of the second transgene, with a complete loss of expression after 7 days, paralleling an increase in serum NAb titers. Brain parenchymal injection was explored to circumvent the presence of NAbs. Mice systemically pre-treated with an AAV-PHP.B were injected intra-cerebrally with an AAV-PHP.B expressing GFP. After 2 weeks, marked GFP expression in the cerebellum was evident, showing that pre-existing NAbs did not affect the AAV-PHP.B directly injected into the brain. In contrast, reversing the injection order, i.e., cerebellar injection followed by systemic injection, completely eliminated expression of the second transgene. We confirmed that intra-cerebellar injection produced NAbs in the serum, but not in the cerebrospinal fluid (CSF). Our results indicate that the preclusion of brain transduction by a second AAV-PHP.B administration begins from the first day following systemic injection and is established within 1 week. Serum NAbs can be avoided by directly injecting AAV PHP.Bs into brain tissue. PMID- 30291584 TI - Crybb2 Mutations Consistently Affect Schizophrenia Endophenotypes in Mice. AB - As part of the betagamma-superfamily, betaB2-crystallin (CRYBB2) is an ocular structural protein in the lens, and mutation of the corresponding gene can cause cataracts. CRYBB2 also is expressed in non-lens tissue such as the adult mouse brain and is associated with neuropsychiatric disorders such as schizophrenia. Nevertheless, the robustness of this association as well as how CRYBB2 may contribute to disease-relevant phenotypes is unknown. To add further clarity to this issue, we performed a comprehensive analysis of behavioral and neurohistological alterations in mice with an allelic series of mutations in the C-terminal end of the Crybb2 gene. Behavioral phenotyping of these three betaB2 mutant lines Crybb2O377, Crybb2Philly, and Crybb2Aey2 included assessment of exploratory activity and anxiety-related behavior in the open field, sensorimotor gating measured by prepulse inhibition (PPI) of the acoustic startle reflex, cognitive performance measured by social discrimination, and spontaneous alternation in the Y-maze. In each mutant line, we also quantified the number of parvalbumin-positive (PV+) GABAergic interneurons in selected brain regions that express CRYBB2. While there were allele-specific differences in individual behaviors and affected brain areas, all three mutant lines exhibited consistent alterations in PPI that paralleled alterations in the PV+ cell number in the thalamic reticular nucleus (TRN). The direction of the PPI change mirrored that of the TRN PV+ cell number thereby suggesting a role for TRN PV+ cell number in modulating PPI. Moreover, as both altered PPI and PV+ cell number are schizophrenia-associated endophenotypes, our result implicates mutated Crybb2 in the development of this neuropsychiatric disorder. PMID- 30291585 TI - Inter-Laboratory Characterization of the Velocity Field in the FDA Blood Pump Model Using Particle Image Velocimetry (PIV). AB - PURPOSE: A credible computational fluid dynamics (CFD) model can play a meaningful role in evaluating the safety and performance of medical devices. A key step towards establishing model credibility is to first validate CFD models with benchmark experimental datasets to minimize model-form errors before applying the credibility assessment process to more complex medical devices. However, validation studies to establish benchmark datasets can be cost prohibitive and difficult to perform. The goal of this initiative sponsored by the U.S. Food and Drug Administration is to generate validation data for a simplified centrifugal pump that mimics blood flow characteristics commonly observed in ventricular assist devices. METHODS: The centrifugal blood pump model was made from clear acrylic and included an impeller, with four equally spaced, straight blades, supported by mechanical bearings. Particle Image Velocimetry (PIV) measurements were performed at several locations throughout the pump by three independent laboratories. A standard protocol was developed for the experiments to ensure that the flow conditions were comparable and to minimize systematic errors during PIV image acquisition and processing. Velocity fields were extracted at the pump entrance, blade passage area, back gap region, and at the outlet diffuser regions. A Newtonian blood analog fluid composed of sodium iodide, glycerin, and water was used as the working fluid. Velocity measurements were made for six different pump flow conditions, with the blood-equivalent flow rate ranging between 2.5 and 7 L/min for pump speeds of 2500 and 3500 rpm. RESULTS: Mean intra- and inter-laboratory variabilities in velocity were ~ 10% at the majority of the measurement locations inside the pump. However, the inter laboratory variability increased to more than ~ 30% in the exit diffuser region. The variability between the three laboratories for the peak velocity magnitude in the diffuser region ranged from 5 to 25%. The bulk velocity field near the impeller changed proportionally with the rotational speed but was relatively unaffected by the pump flow rate. In contrast, flow in the exit diffuser region was sensitive to both the flow rate and the rotational speed. Specifically, at 3500 rpm, the exit jet tilted toward the inner wall of the diffuser at a flow rate of 2.5 L/min, but the jet tilted towards the outer wall when the flow rate was 7 L/min. CONCLUSIONS: Inter-laboratory experimental mean velocity data (and the corresponding variance) were obtained for the FDA pump model and are available for download at https://nciphub.org/wiki/FDA_CFD . Experimental datasets from the inter-laboratory characterization of benchmark flow models, including the blood pump model presented herein and our previous nozzle model, can be used for validating future CFD studies and to collaboratively develop guidelines on best practices for verification, validation, uncertainty quantification, and credibility assessment of CFD simulations in the evaluation of medical devices (e.g. ASME V&V 40 standards working group). PMID- 30291586 TI - Utilization and Perceptions of Drop-in Center Services Among Youth Experiencing Homelessness. AB - Drop-in centers offer a range of services to assist unaccompanied youth experiencing homelessness, but little is known about their perceptions of drop-in centers or use of different services. A random sample of 273 youth experiencing homelessness in the Los Angeles area who had ever used a drop-in center was surveyed. Most youth heard about local drop-in centers from peers (65.1%). They generally reported positive perceptions of the drop-in center environment, staff, and clients; overall, 57.8% were "very" or "extremely" satisfied with the services they had received. Nearly all youth cited basic services (e.g., food, showers, clothes) as a reason they went to drop-in centers; far fewer reported going to obtain higher-level services (e.g., case management). Perceptions and utilization did not differ by sexual orientation; however, non-white youth were more likely than Whites to use drop-in centers for certain higher-level services. Strategies for engaging youth in drop-in center services are discussed. PMID- 30291587 TI - Superior Mesenteric Artery Syndrome: a Prospective Study in a Single Institution. AB - BACKGROUND: Superior mesenteric artery syndrome (SMAS) is a rare cause of duodenal obstruction, resulting from the compression of the duodenum between superior mesenteric artery and aorta. This prospective registry aims to describe demographic, clinical, and outcome features of patients suffering from SMAS and to point out the indications for surgery. METHODS: Between 2008 and 2016, patients with chronic gastrointestinal symptoms and diagnosis of SMAS were included. Demographics, clinical presentation, diagnosis, and surgical outcome were recorded. Symptoms were investigated with a standardized questionnaire. The diagnosis was achieved through barium swallow, CT/MR angiography (aortomesenteric angle <= 22 degrees , distance <= 8 mm), endoscopy. All patients underwent duodenojejunostomy +/- distal duodenum resection. At follow-up, symptom score and barium swallow were re-evaluated. RESULTS: Thirty-nine patients (11 M/28 F, median age 38 years, median BMI 17.8 kg/m2) were included. Barium swallow showed a gastroduodenal dilation in 57% of patients, and a delayed gastroduodenal emptying in 38%. Median aortomesenteric angle was 11 degrees and distance was 5 mm. All patients underwent duodenojejunostomy, and in 32 patients, a distal duodenum resection was also performed. At a median follow-up of 47 months, the overall symptom score significantly dropped (10 vs. 32, p < 0.0001) and BMI increased (19.5 vs. 17.8, p < 0.0001). Barium swallow at 2 months postoperatively showed an improvement in terms of gastroduodenal dilation and emptying in 38% of patients with preoperative pathological findings. CONCLUSIONS: SMAS is a rare condition that should be suspected in cases of chronic, refractory upper digestive symptoms, particularly in females with low BMIs. Surgical treatment may improve symptoms and quality of life, although it is not curative in all cases. ClinicalTrials.gov Identifier: NCT03416647. PMID- 30291588 TI - The epigenetic landscape in the cardiovascular complications of diabetes. AB - A growing body of evidence suggests that epigenetic modifications-changes to the genome that do not involve changes in DNA sequence-may significantly derail transcriptional programs implicated in angiogenesis, oxidative stress and inflammation, thus fostering cardiovascular damage in patients with diabetes. Notably, adverse epigenetic signals acquired over the life course can be transmitted to the offspring, and may contribute to early cardiovascular phenotypes in the young generations. Hyperglycaemia and insulin resistance-key hallmarks of diabetes-induce an array of epigenetic modifications (i.e., DNA methylation, histone marks, and non-coding RNAs) which are responsible for a long lasting impairment of vascular and cardiac function, even after intensive glycemic control. Hence, unveiling the "epigenetic landscape" in patients with diabetes may provide a post-genomic snapshot of global cardiovascular risk, and may furnish the tools to design personalized, epigenetic-based therapies to alleviate the burden of cardiovascular disease in diabetic patients. The present review aims to acquaint the scientific community with the rapidly advancing field of epigenetics and its implications in the cardiovascular complications of diabetes. PMID- 30291589 TI - Clinical inertia, reverse clinical inertia, and medication non-adherence in type 2 diabetes. AB - PURPOSE: Clinical inertia and medication non-adherence are thought to contribute largely to the suboptimal glycemic control in many patients with type 2 diabetes. The present review explores the relations between A1C targets, clinical inertia and medication non-adherence in type 2 diabetes. METHODS: We searched PubMed for English-language studies published from 2001 through June 1, 2018. We also manually searched the references of selected articles, reviews, meta-analyses, and practice guidelines. Selected articles were mutually agreed upon by the authors. RESULTS: Clinical inertia is the failure of clinicians to initiate or intensify therapy when indicated, while medication non-adherence is the failure of patients to start or continue therapy that a clinician has recommended. Although clinical inertia may occur at all stages of diabetes treatment, the longest delays were reported for initiation or intensification of insulin. Medication non-adherence to antidiabetic drugs may range from 53 to 65% at 1 year and may be responsible for uncontrolled A1C in about 23% of cases. Reverse clinical inertia can be acknowledged as the failure to reduce or change therapy when no longer needed or indicated. Clinical inertia and medication non-adherence are difficult to address: clinician-and patient-targeted educational programs, more connected communications between clinicians and patients, the help of other health professional figures (nurse, pharmacist) have been explored with mixed results. CONCLUSIONS: Both clinical inertia and medication non-adherence remain significant barriers to optimal glycemic targets in type 2 diabetes. Moreover, part of clinical inertia may be a way through which clinicians face current uncertainty in medicine, including some dissonance among therapeutic guidelines. Scientific associations should find an agreement about how to measure and report clinical inertia in clinical practice and should exhort clinicians to consider reverse clinical inertia as a cause of persisting inappropriate therapy in vulnerable patients. PMID- 30291590 TI - Representation of Multiple Cellular Phenotypes Within Tissue-Level Simulations of Cardiac Electrophysiology. AB - Distinct electrophysiological phenotypes are exhibited by biological cells that have differentiated into particular cell types. The usual approach when simulating the cardiac electrophysiology of tissue that includes different cell types is to model the different cell types as occupying spatially distinct yet coupled regions. Instead, we model the electrophysiology of well-mixed cells by using homogenisation to derive an extension to the commonly used monodomain or bidomain equations. These new equations permit spatial variations in the distribution of the different subtypes of cells and will reduce the computational demands of solving the governing equations. We validate the homogenisation computationally, and then use the new model to explain some experimental observations from stem cell-derived cardiomyocyte monolayers. PMID- 30291591 TI - A Continuum Mechanics Model of Enzyme-Based Tissue Degradation in Cancer Therapies. AB - We propose a mathematical model to describe enzyme-based tissue degradation in cancer therapies. The proposed model combines the poroelastic theory of mixtures with the transport of enzymes or drugs in the extracellular space. The effect of the matrix-degrading enzymes on the tissue composition and its mechanical response are accounted for. Numerical simulations in 1D, 2D and axisymmetric (3D) configurations show how an injection of matrix-degrading enzymes alters the porosity of a biological tissue. We eventually exhibit numerically the main consequences of a matrix-degrading enzyme pretreatment in the framework of chemotherapy: the removal of the diffusive hindrance to the penetration of therapeutic molecules in tumors and the reduction of interstitial fluid pressure which improves transcapillary transport. Both effects are consistent with previous biological observations. PMID- 30291592 TI - Real-time dual-modal vein imaging system. AB - PURPOSE: In this paper, we present a vein imaging system to combine reflectance mode visible spectrum images (VIS) with transmission mode near-infrared (NIR) images in real time. Clear vessel localization is achieved in this manner with combined NIR-VIS dual-modal imaging. METHODS: Transmission and reflectance mode optical instrumentation is used to combine VIS and NIR images. Two methods of displaying the combined images are demonstrated here. We have conducted experiments to determine the system's resolution, alignment accuracy, and depth penetration. Vein counts were taken from the hands of test subjects using the system and compared with vein counts taken by visual analysis. RESULTS: Results indicate that the system can improve vein detection in the human hand while detecting veins of a diameter < 0.5 mm at any working distance and of a 0.25 mm diameter at an optimal working distance of about 30 cm. The system has also been demonstrated to clearly detect silicone vessels with artificial blood of diameter 2, 1, and 0.5 mm diameter under a tissue depth of 3 mm. In a study involving 25 human subjects, we have demonstrated that vein visibility was significantly increased using our system. CONCLUSIONS: The results indicate that the device is a high-resolution solution to near-surface venous imaging. This technology can be applied for IV placement, morphological analysis for disease state detection, and biometric analysis. PMID- 30291593 TI - The role of semantic transparency in visual word recognition of compound words: A megastudy approach. AB - Previous studies on visual word recognition of compound words have provided evidence for the influence of lexical properties (e.g., length, frequency) and semantic transparency (the degree of relatedness in meaning between a compound word and its constituents) in morphological processing (e.g., to what extent is doorbell influenced by door and bell?). However, a number of questions in this domain, which are difficult to address with the available methodological resources, are still unresolved. We collected semantic transparency scores for 2,861 compound words at the constituent level (i.e., how strongly the overall meaning of a compound word is related to that of each constituent) and analyzed their effects on speeded pronunciation and lexical decision performance for the compound words using the English Lexicon Project ( http://elexicon.wustl.edu ) data. The results from both tasks indicated that our human-judged semantic transparency ratings for both the first and second constituents play a significant role in compound word processing. Moreover, additional analyses indicated that the human-judged semantic transparency scores at the constituent level accounted for more variance in compound word recognition performance than did either whole-word semantic transparency scores or corpus-based semantic distance scores. PMID- 30291594 TI - Hepatic arterialization can predict the development of collateral veins in patients with HCV-related liver disease. AB - PURPOSE: Arrival time parametric imaging (At-PI) using contrast-enhanced ultrasonography (CEUS) is a procedure for evaluating liver disease progression in chronic hepatitis C infection (CHC). We investigated At-PI diagnostic efficacy in predicting development of collateral veins. METHODS: In total, 171 CHC patients underwent CEUS and upper gastrointestinal (UGI) endoscopy before liver biopsy. Conventional US was performed before CEUS to identify paraumbilical veins (PV) or splenorenal shunts (SRS). After intravenous perflubutane, contrast dynamics of liver segments 5-6 and the right kidney were saved as raw data. At-PI image ratio of red (ROR) pixels to the entire liver was analyzed. Receiver operating characteristic (ROC) curves were generated to investigate the utility of At-PI for collateral vein identification. RESULTS: Conventional US revealed PV in two patients and SRS in five patients; UGI endoscopy detected esophageal varices (EV) in eight patients. Diagnostic capability of At-PI for detecting PV, SRS, and EV was satisfactory, and high for PV and SRS [PV; area under the ROC curve (AUROC) 0.929, cutoff value 77.9%, SRS; AUROC 0.970, cutoff value 82.0%, EV; AUROC 0.883, cutoff value 66.9%]. CONCLUSIONS: Evaluation of hepatic arterialization by At-PI was useful for predicting collateral vein development in CHC patients.

PMID- 30291598 TI - Sexual Behavior Mediates the Relationship Between Sexual Approach Motives and Sexual Outcomes: A Dyadic Daily Diary Study. AB - Recent studies show that sexual approach (SA) motives, i.e., having sex to achieve a positive state such as sexual pleasure, are associated with higher sexual and relationship satisfaction. However, mechanisms linking SA motives to these outcomes are poorly understood, and the important distinction between SA motives that are self-directed (e.g., self-gratification) and other-directed (e.g., pleasing one's partner) has received little empirical attention, particularly in the everyday context of couples' sexuality. The present study focused, at an event level, on the associations between self-directed and other directed SA motives, and sexual satisfaction and perceived partner responsiveness (PPR, an aspect of relationship intimacy). We also examined the mediating role of the couple's sexual behavior in these associations. Data were collected over a month-long daily diary study involving 35 newlywed heterosexual couples and analyzed using the Actor-Partner Interdependence Model. Results showed that men and women's self-directed SA motives were associated with their own higher sexual satisfaction and, in men, with their female partners' sexual satisfaction as well. For both men and women, these associations were mediated by sexual behavior: Self-directed SA motives were associated with more genitally focused sexual behavior (e.g., vaginal intercourse, oral sex), in turn associated with higher sexual satisfaction. For men, other-directed SA motives were associated with their own greater PPR and with that of their female partners. For women, self-directed SA motives were associated with their own greater PPR and with that of their male partners. Sexual behavior did not mediate associations with PPR. Theoretically, these findings support dyadic models of sexual satisfaction and intimacy and indicate that self-directed SA motives may be more important to sexual satisfaction than other-directed motives. Clinically, they support sex therapy approaches that integrate both partners and suggest that sexual motives and behavior may be relevant targets for intervention. PMID- 30291599 TI - Gender Identity and Sexual Function in 46,XX Patients with Congenital Adrenal Hyperplasia Raised as Males. AB - In individuals with congenital adrenal hyperplasia (CAH) and 46,XX karyotype, androgens produced by the adrenal glands during the intrauterine development promote virilization of the genitals, which may even result in the development of a well-formed penis. Some of these children with late diagnosis are registered as males after birth. After obtaining approval from the internal review board, we evaluated gender identity and sexual function in four 46,XX severely virilized patients with CAH, who were originally registered and raised as males, assisted in our Disorders of Sexual Development Clinic. The evaluation consisted of questionnaires to assess gender identity and sexual activity and interview with the multidisciplinary team that provides care for these patients. The patients underwent surgery to remove uterus, ovaries, and remaining vaginal structures, in addition to implantation of testicular prosthesis and correction of hypospadias, when necessary. All four patients have developed a clear male gender identity, and when evaluated for sexual activity, they have reported having erections, libido, orgasms, and sexual attraction to women only. Two of these 4 patients had satisfactory sexual intercourses when assessed using the International Index of Erectile Function questionnaire. The other two patients who never had sexual intercourse reported not having a partner for sexual activity; one is 18 years old, and the other is 14 years old. This study showed that this group of 46,XX severely virilized patients with CAH, registered and raised as males, adapted well to the assigned male gender, with satisfactory sexual function in patients who had sexual intercourse. PMID- 30291600 TI - Interactions Between Direct and Structural Violence in Sexual Harassment Against Spanish and Unauthorized Migrant Women. AB - This article analyzes the intersection of direct and indirect violence against Spanish women and unauthorized migrant women working in precarious jobs in Almeria (Spain). Specifically, it seeks to understand how unauthorized migrant women define violence, the relationship between sexual harassment and other types of direct violence (such as intimate partner violence), and structural, legal, and cultural violence. To do this, we apply a multilevel intersectional analysis focusing on 32 interviews with Spanish and unauthorized migrant women. Three levels of intersectionality are shown. In the first, the interviewees do not label verbal abuse as sexual harassment. They attribute the abuse to their work. In the second, sexual harassment seems to be tied to "respect" and not "love," which explains why sexual harassment has less devastating consequences for women than intimate partner violence. In the third, experiences of sexual harassment differ between Spanish women and unauthorized migrant women, and a combination of sexual harassment and xenophobic and racist behavior occasionally appeared. PMID- 30291602 TI - Screening for Adverse Drug Events: a Randomized Trial of Automated Calls Coupled with Phone-Based Pharmacist Counseling. AB - BACKGROUND: Medication adverse events are important and common yet are often not identified by clinicians. We evaluated an automated telephone surveillance system coupled with transfer to a live pharmacist to screen potentially drug-related symptoms after newly starting medications for four common primary care conditions: hypertension, diabetes, depression, and insomnia. METHODS: Cluster randomized trial with automated calls to eligible patients at 1 and 4 months after starting target drugs from intervention primary care clinics compared to propensity-matched patients from control clinics. Primary and secondary outcomes were physician documentation of any adverse effects associated with newly prescribed target medication, and whether the medication was discontinued and, if yes, whether the reason for stopping was an adverse effect. RESULTS: Of 4876 eligible intervention clinic patients who were contacted using automated calls, 776 (15.1%) responded and participated in the automated call. Based on positive symptom responses or request to speak to a pharmacist, 320 patients were transferred to the pharmacist and discussed 1021 potentially drug-related symptoms. Of these, 188 (18.5%) were assessed as probably and 479 (47.1%) as possibly related to the medication. Compared to a propensity-matched cohort of control clinic patients, intervention patients were significantly more likely to have adverse effects documented in the medical record by a physician (277 vs. 164 adverse effects, p < 0.0001, and 177 vs. 122 patients discontinued with documented adverse effects, p < 0.0001). DISCUSSION: Systematic automated telephone outreach monitoring coupled with real-time phone referral to a pharmacist identified a substantial number of previously unidentified potentially drug-related symptoms, many of which were validated as probably or possibly related to the drug by the pharmacist or their physicians. Multiple challenges were encountered using the interactive voice response (IVR) automated calling system, suggesting that other approaches may need to be considered and evaluated. TRIAL REGISTRATION: ClinicalTrials.gov : NCT02087293. PMID- 30291603 TI - Community Health Centers Could Provide Better Outsourced Primary Care for Veterans. AB - The "VA Mission Act of 2018" will expand the current "Choice Program" legislation of 2014, which has enabled outsourcing of VA care to private physicians. As the ranks of Veteran patients swell, Congress intended that the Mission Act will help relieve the VHA's significant access problems. We contend that this new legislation will have negative consequences for veterans by diverting support from our VA system of 1300 hospitals and clinics. We recommend modification of this legislation, promoting much greater utilization of Community Health Centers (CHCs) for veterans outsourced primary care. In support of this proposal, we describe (1) features of the "VA Mission Act" relevant to outsourcing, (2) the challenges of the present "Choice Program" and likely future obstacles with the new legislation, and (3) the advantages of expanding CHC VA outsourced primary care. This policy would focus more on providing specialized care for veterans in the VA system, while coordinating with CHCs for the necessary expanded outsourced, holistic primary care. We conclude that failure to develop an incremental, cost-effective alternative as described herein represents a potential threat to adequate future support of our VA hospital system, and thus outstanding care for our veterans. PMID- 30291604 TI - Patient Activation Changes as a Potential Signal for Changes in Health Care Costs: Cohort Study of US High-Cost Patients. AB - BACKGROUND: Programs to improve quality of care and lower costs for the highest utilizers of health services are proliferating, yet such programs have difficulty demonstrating cost savings. OBJECTIVE: In this study, we explore the degree to which changes in Patient Activation Measure (PAM) levels predict health care costs among high-risk patients. PARTICIPANTS: De-identified claims, demographic data, and serial PAM scores were analyzed on 2155 patients from multiple medical groups engaged in an existing Center for Medicare and Medicaid Innovation-funded intervention over 3 years designed to activate and improve care coordination for high-risk patients. DESIGN: In this prospective cohort study, four levels of PAM (from low to high) were used as the main predictor variable. We fit mixed linear models for log10 of allowed charges in follow-up periods in relation to change in PAM, controlling for baseline PAM, baseline costs, age, sex, income, and baseline risk score. MAIN MEASURES: Total allowed charges were derived from claims data for the cohort. PAM scores were from a separate database managed by the local practices. KEY RESULTS: A single PAM level increase was associated with 8.3% lower follow-up costs (95% confidence interval 2.5-13.2%). CONCLUSIONS: These findings contribute to a growing evidence base that the change in PAM score could serve as an early signal indicating the impact of interventions designed for high cost, high-needs patients.

PMID- 30291606 TI - Chitosan oligosaccharides alleviate PM2.5-induced lung inflammation in rats. AB - Air pollution of particulate matter (PM), especially PM2.5, has become a major public health problem in China. Exploration of therapeutic and preventive measures against PM2.5 toxicity is of practical significance. The aim of this study was to examine the inhibitory effects of chitosan oligosaccharides (COS) on PM2.5-induced lung inflammation in rats. Forty SPF (specific pathogen-free) male Wistar rats weighing 200-220 g were randomly divided into four groups: control group, COS group, PM2.5 group, and PM2.5+COS group. COS was pre-administered to rats by gavage at a single dose of 500 mg/kg 2 h before intratracheal instillation of PM2.5 at a single dose of 1.2 mg/kg daily for 3 consecutive days. Normal saline (NS) was used as negative control. Twenty-four hours after the last instillation of PM2.5, rats were sacrificed and subjected to bronchoalveolar lavage (BAL). The BAL fluids (BALF) were collected for measurement of levels of total proteins, lactate dehydrogenase (LDH), interleukin-1 (IL-1beta), IL-8, and tumor necrosis factor-alpha (TNF-alpha) using colorimetric or ELISA kits. Levels of total proteins, LDH activities, and pro-inflammatory mediators including IL 1beta, IL-8, and TNF-alpha in BALF of rats in PM2.5 group significantly increased in comparison with those of the control group. Pre-treatment of rats with COS markedly blocked PM2.5-induced increase in LDH, IL-8, and TNF-alpha levels in BALF. In conclusion, PM2.5 exposure induces rat lung inflammation, which could be ameliorated by the pre-treatment of COS. PMID- 30291607 TI - Magnesium depletion suppresses the anti-grazer colony formation in Scenedesmus obliquus. AB - In aquatic ecosystems, many phytoplankton species have evolved various inducible defense mechanisms against the predation. The expression of these defenses is affected by environmental conditions such as nutrient availability. Here, we investigated the anti-grazer colony formation in Scenedesmus obliquus at different magnesium concentrations (0-7.3 mg L-1 Mg2+) in the presence of zooplankton (Daphnia)-derived infochemicals. Results showed that at adequate Mg2+, S. obliquus formed high proportions of multi-celled (e.g., four- and eight celled) colonies, resulting in significantly increased number of cells per colony in response to Daphnia filtrate. On the other hand, in Mg2+-deficient treatment, the proportion of multi-celled colonies decreased, together with reduced algal growth rate and photosynthetic efficiency. Finally, the treatment without Mg2+ strongly suppressed the formation of large colony (mainly eight-celled colonies), whereas the algal growth rate was comparable to that in Mg2+ sufficient treatment. Despite the inhibition of colony formation, the time reaching the maximum number of cells per colony was not affected by the Mg2+ concentration, which generally took three days in all groups. Our results indicate that Mg2+ deficient/absent environments significantly reduced anti-grazing colony formation but not the algal growth, suggesting strong dependability of this morphological defensive trait to magnesium fluctuation in S. obliquus.

Using an event study analysis, we examine whether these price adjustments have impacted air quality. We test the abnormal returns of 12 price adjustments between 2014 and 2015 in 51 major cities of China. The results show that the impact on air quality of refined oil price decreases is larger than the impact of oil price increases. Although results indicate air quality has deteriorated, the impact is insignificant for most of the cities. Consequently, we conclude that price suspension of refined oil has had a negligible impact on air quality. This policy is not a viable method to improve the air quality in the short run. PMID- 30291609 TI - Genotoxicity of water samples from an area of the Pampean region (Argentina) impacted by agricultural and livestock activities. AB - The aim of this study was to assess the genotoxic potential of surface waters located in a rural area in the north east of Buenos Aires province (Argentina) using the Allium cepa test. Water samples were collected at four sites located in a drainage channel and two sites on the Burgos stream that receives water from the channel, taking into account the sowing and harvesting months and rainfall periods. Analytical determinations revealed high total concentrations of Cd, Cu, Pb, and Zn (maximum values: 0.030, 0.252, 0.176, and 0.960 mg L-1, respectively), and concentrations of glyphosate and its metabolite aminomethylphosphonic acid (AMPA), with maximum values of 13.6 and 9.75 MUg L-1, respectively. Statistically positive correlations were observed between the total metal concentrations and precipitation. No cytotoxicity (mitotic index MI) was observed in A. cepa. However, several water samples showed significant increases in micronucleus (MN) frequencies with respect to the controls. No correlations were observed between MN and the abiotic variables or precipitation. These results showed a state of deterioration in the water quality at the rural area studied in Buenos Aires province, and heavy metal contamination may contribute to the genotoxic activity. A. cepa was shown to be a useful tool for the detection of genotoxicity in water samples from areas with agricultural and livestock activities.

AB - In this paper, the modified multi-walled carbon nanotubes were prepared by beta cyclodextrin denoted as beta-CD-MWNTs. The structure and morphology of beta-CD MWNTs was characterized by TEM and the dynamic adsorption of p-nitrophenol on beta-CD-MWNTs was studied by the Thomas model. Some affecting factors of dynamic adsorption and the adsorbent regeneration process such as the sewage concentration, the amount of absorbent in column, including the type of reagent, solid-liquid ratio, regeneration time, and regeneration times were investigated and optimized. The results indicated that the p-nitrophenol removal rate could reach 84% under stuffing 2 g beta-CD-MWNTs. The curves of p-nitrophenol's dynamic adsorption conformed to the Thomas model. Moreover, the adsorption capacity of regenerated beta-CD-MWNTs was similar to the fresh beta-CD-MWNT column. The optimal conditions of regenerations of beta-CD-MWNTs were shown as follows: the type of reagent is anhydrous ethanol, the solid-liquid ratio is 200:40 (mg/mL) and the regeneration time is 120 min.

AB - This study presents an efficient and facile method for biosynthesis of silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) using aqueous extract of burdock root (BR), A. lappa, and their applications. The nanoparticles were characterized by ultraviolet-visible spectrophotometry, X-ray diffraction, transmission electron microscopy, energy dispersive X-ray, thermogravimetry, and differential thermal analysis. AgNPs capped the BR extract (BR-AgNPs) possessed roughly spherical geometry with an average diameter of 21.3 nm while uneven geometry of AuNPs capped the BR extract (BR-AuNPs) showed multi shapes in average size of 24.7 nm. The BR-AgNPs strongly inhibited five tested microorganism strains. In particular, the nanoparticles showed excellent catalytic activity for the conversion of pollutants within wastewater. Pseudo-first-order rate constants for the degradation of 4-nitrophenol, methyl orange, and rhodamine B were respectively found 6.77 * 10-3, 3.70 * 10-3, and 6.07 * 10-3 s-1 for BR-AgNPs and 6.87 * 10-3, 6.07 * 10-3, and 7.07 * 10-3 s-1 for BR-AuNPs.

AB - Chitosan (CS), synthesized from chitin chemically extracted from shrimp shells, was used for the synthesis of magnetic chitosan nanoparticles (Fe3O4-CSN), which makes the adsorbent easier to separate. Fe3O4-CSN was used for the removal of toxic metals such as vanadium (V(V)) and palladium (Pd(II)) ions from aqueous solutions. Influencing factors on the adsorption process such as pH, contact time, adsorbent dosage, and agitation speed were investigated. A competitive adsorption of V(V) and Pd(II) ions for the active sites was also studied. The monolayer maximum adsorption capacities (Qm) of 186.6 and 192.3 mg/g were obtained for V(V) and Pd(II) ions, respectively. The pseudo-second-order equation gave the best fit for the kinetic data, implying that chemisorption was the determining step. Freundlich model yielded a much better fit than the other adsorption models assessed (Langmuir, Temkin and Dubinin-Radushkevich). Thus, the adsorption of V(V) and Pd(II) ions onto Fe3O4-CSN is a combination of physical and chemical adsorption, as based on the kinetics and equilibrium study. Generally, physical adsorption is the mechanism that governs the system, while chemical adsorption is the slowest adsorption step that takes place. Thermodynamic studies displayed that the adsorption process was exothermic and spontaneous. Removal efficiencies of 99.9% for V(V) and 92.3% for Pd(II) ions were achieved, implying that Fe3O4-CSN adsorbent had an excellent ability for the removal of the metal ions from real industrial wastewaters without remarkable matrix effect. Graphical abstract ?. PMID- 30291615 TI - A response surface methodology for optimization of 2,4-dichlorophenoxyacetic acid removal from synthetic and drainage water: a comparative study. AB - The potential of a granular activated carbon (GAC), a rice husk biochar (BRH), and multi-walled carbon nanotubes (MWCNTs) for removing 2,4-dichlorophenoxyacetic acid (2,4-D) from simulated wastewater and drainage water has been evaluated. In this regard, a response surface methodology (RSM) with a central composite design (CCD) (CCD-RSM design) was used to optimize the removal of 2,4-D from simulated wastewater under different operational parameters. The maximum adsorption capacities followed the order GAC > BRH > MWCNTs, whereas the equilibrium time increased in the order MWCNTs < GAC < BRH. In the case of GAC and BRH, the 2,4-D removal percentage increased significantly upon increasing the adsorbent dosage and temperature and decreased upon increasing the initial 2,4-D concentration and pH. The results showed that the contact time and temperature were not important as regards the adsorption efficiency of 2,4-D by MWCNTs, whereas rapid removal of 2,4-D from simulated wastewater was achieved within the first 5 min of contact with the MWCNTs. The results confirmed that the Freundlich isotherm model with the highest coefficient of determination (R2) and the lowest standard error of the estimate (SEE) satisfactorily fitted the 2,4-D experimental data. In addition, successful usage of the three adsorbents investigated was observed for removal of 2,4-D from drainage water from an agricultural drainage system. An economic analysis with a rate of return (ROR) method indicated that BRH could be used as an eco-friendly, low-cost, versatile, and high adsorption capacity alternative to GAC and MWCNTs for the removal of 2,4-D.

AB - Fly ash, a coal combustion residue produced by Termotasajero in Colombia, has been hydrothermally treated after an alkaline fusion to produce zeolite without addition of silicon or aluminum. The starting material was thoroughly mixed with NaOH, in a 1:1.2 mass ratio, to obtain a homogeneous mixture that was heated to 100 degrees C during different times (6, 8, and 10 h) and three zeolite samples were produced. The samples were characterized by XRD, SEM, XRF, Mossbauer spectroscopy, and N2 physisorption. According to characterization results (high surface area and appropriate morphological properties including crystallinity) and synthesis time, zeolitic catalyst synthesized with 8 h of hydrothermal treatment was selected to perform further analysis. This sample consisted of a mixture of zeolite X and zeolite A of high surface area (301 m2 g-1) and a Fe content of 6% wt/wt. The zeolite was used as a catalyst for the Fenton oxidation of Orange II. Experiments were performed in a laboratory batch reactor at 70 degrees C and constant pH = 3, using different concentrations of H2O2. When the stoichiometric amount of H2O2 was used, good mineralization (XTOC = 45%), complete discoloration, and oxidant consumption were obtained after 240 min of reaction. The sample retained activity after 16 h of usage. The presence of Fe in the reaction media was always detected and a homogeneous Fenton mechanism induced by surface-leached iron is suggested.

AB - Cadmium (Cd) can be transferred and accumulated in spiders, posing a survival risk to them. To analyze potential biological damage caused by Cd accumulation and relevant detoxification strategies employed by spiders in response to Cd exposure, we conducted transcriptome analysis of the 5th instar spider P. pseudoannulata, a common spider species playing a vital role in natural pest control in agricultural fields of southern China. We obtained 92,778 unigenes with an average length of 1104 bp and identified 302, 655, and 424 differentially expressed genes (DEGs) in the spiders fed with Cd-containing fruit flies for 2, 5, and 8 days, respectively. Results showed that the body mass of Cd-containing P. pseudoannulata were reduced when compared with controls, presumably due to delayed maturation of tissues and organs. Meanwhile, functional analysis of DEGs indicated that Cd may have a negative effect on neural signal transduction and molt cycle of the spider. For defense strategies, detoxification enzymes like glutathione S-transferase (GST), catalase (CAT), superoxide dismutase (SOD), and P450, and typical proteins like heat shock protein and metallothionein were all differentially expressed in response to Cd stress. Besides, innate immune responses like toll-like receptor signaling pathways were also upregulated. Multiple critical Cd-responsive genes involved in biological damage, detoxification, and immune response were identified, providing referable foundation for further research on Cd toxicity to P. pseudoannulata.

AB - Alzheimer's disease is a progressive neurodegenerative disorder and the most common form of dementia. Like many neurological disorders, Alzheimer's disease has a sex-biased epidemiological profile, affecting approximately twice as many women as men. The cause of this sex difference has yet to be elucidated. To identify molecular correlates of this sex bias, we investigated molecular pathology in females and males using the 5XFamilial Alzheimer's disease mutations (5XFAD) genetic mouse model of Alzheimer's disease. We profiled the transcriptome and proteome of the mouse hippocampus during early stages of disease development (1, 2, and 4 months of age). Our analysis reveals 42 genes that are differentially expressed between disease and wild-type animals at 2 months of age, prior to observable plaque deposition. In 4-month-old animals, we detect 1,316 differentially expressed transcripts between transgenic and control 5XFAD mice, many of which are associated with immune function. Additionally, we find that some of these transcriptional perturbations are correlated with altered protein levels in 4-month-old transgenic animals. Importantly, our data indicate that female 5XFAD mouse exhibit more profound pathology than their male counterparts as measured by differences in gene expression. We also find that the 5XFAD transgenes are more highly expressed in female 5XFAD mice than their male counterparts, which could partially account for the sex-biased molecular pathology observed in this dataset. PMID- 30291624 TI - The neurobiology of impulsivity and substance use disorders: implications for treatment. AB - Impulsivity is strongly associated with substance use disorders (SUDs). Our review discusses impulsivity as an underlying vulnerability marker for SUDs, and treatment of co-occurring impulsivity in SUDs. Three factors should be considered for the complex relationship between impulsivity and a SUD: (1) the trait effect of impulsivity, centering on decreased cognitive and response inhibition, (2) the state effect resulting from either acute or chronic substance use on brain structure and function, and (3) the genetic and environmental factors (e.g., age and sex) may influence impulsive behavior associated with SUDs. Both subjective and objective measures are used to assess impulsivity. Together, treatment developments (pharmacological, behavioral, and neurophysiological) should consider these clinically relevant dimensions assessed by a variety of measures, which have implications for treatment matching in individuals with SUD. Despite its heterogeneity, impulsivity is a marker associated with SUDs and may be understood as an imbalance of bottom-up and top-down neural systems. Further investigation of these relationships may lead to more effective SUD treatments. PMID- 30291625 TI - Clinical factors predicting treatment resistant depression: affirmative results from the European multicenter study. AB - OBJECTIVES: Clinical variables were investigated in the 'treatment resistant depression (TRD)- III' sample to replicate earlier findings by the European research consortium 'Group for the Study of Resistant Depression' (GSRD) and enable cross-sample prediction of treatment outcome in TRD. EXPERIMENTAL PROCEDURES: TRD was defined by a Montgomery and Asberg Depression Rating Scale (MADRS) score >=22 after at least two antidepressive trials. Response was defined by a decline in MADRS score by >=50% and below a threshold of 22. Logistic regression was applied to replicate predictors for TRD among 16 clinical variables in 916 patients. Elastic net regression was applied for prediction of treatment outcome. RESULTS: Symptom severity (odds ratio (OR) = 3.31), psychotic symptoms (OR = 2.52), suicidal risk (OR = 1.74), generalized anxiety disorder (OR = 1.68), inpatient status (OR = 1.65), higher number of antidepressants administered previously (OR = 1.23), and lifetime depressive episodes (OR = 1.15) as well as longer duration of the current episode (OR = 1.022) increased the risk of TRD. Prediction of TRD reached an accuracy of 0.86 in the independent validation set, TRD-I. CONCLUSION: Symptom severity, suicidal risk, higher number of lifetime depressive episodes, and comorbid anxiety disorder were replicated as the most prominent risk factors for TRD. Significant predictors in TRD-III enabled robust prediction of treatment outcome in TRD-I. PMID- 30291626 TI - Aged human skin accumulates mast cells with altered functionality that localize to macrophages and vasoactive intestinal peptide-positive nerve fibres. AB - BACKGROUND: Skin health declines with age and this is partially attributed to immunosenescence. Mast cells (MCs) are innate immune cells that coordinate tissue immune responses integral to skin homeostasis and disease. OBJECTIVES: To understand how MCs contribute to human skin ageing, we investigated how intrinsic ageing impacts MC phenotype and MC relationships with other immune cells and skin structures. METHODS: In photoprotected skin biopsies from young (<= 30 years) and aged (>= 75 years) individuals, immunostaining and spatial morphometry were performed to identify changes in MC phenotype, number, distribution and interaction with the vasculature and nerve fibres. Quantitative polymerase chain reaction was used to measure changes in gene expression related to immune cell activity and neuropeptide signalling. RESULTS: Skin MCs, macrophages and CD8+ T cells increased in number in intrinsically aged vs. young skin by 40%, 44% and 90%, respectively (P < 0.05), while CD4+ T cells and neutrophils were unchanged. In aged skin, MCs were more numerous in the papillary dermis and showed a reduced incidence of degranulation (50% lower than in young, P < 0.01), a conserved tryptase-chymase phenotype and coexpression of granzyme B. In aged skin, MCs increased their association with macrophages (~ 48% vs. ~27%, P < 0.05) and nerve fibres (~29% vs. 16%, P < 0.001), while reducing their interactions with blood vessels (~34% vs. 45%, P < 0.001). Additionally, we observed modulation of gene expression of vasoactive intestinal peptide (VIP; increased) and substance P (decreased) with age; this was associated with an increased frequency of VIP+ nerve fibres (around three times higher in aged skin, P < 0.05), which were strongly associated with MCs (~19% in aged vs. 8% in young, P < 0.05). CONCLUSIONS: In photoprotected skin we observed an accumulation of MCs with increasing age. These MCs have both altered functionality and distribution within the skin, which supports a role for these cells in altered tissue homeostasis during ageing. PMID- 30291627 TI - Risk of excessive intake of vitamins and minerals delivered through public health interventions: objectives, results, conclusions of the meeting, and the way forward. AB - The excessive consumption of certain vitamins and minerals could have deleterious consequences on health and development of individuals and populations. Simultaneous micronutrient-delivery interventions could be challenging in terms of safety as the target populations may overlap, posing a risk of excessive intake of certain micronutrients. The Evidence and Programme Guidance Unit of the Department of Nutrition for Health and Development of the World Health Organization convened a technical consultation on the risk of excessive intake of vitamins and minerals delivered through public health interventions in October 2017. The technical consultation's working groups identified important and emerging technical issues, lessons learned, and research priorities related to (1) planning, implementing, monitoring, and evaluating nutrition programs for the detection and control of the risk of excessive intakes; (2) safety, quality control, and assurance considerations; (3) coordination between public health nutrition interventions and other interventions and sectors; and (4) the legislative framework and policy coherence needed for simultaneous nutrition interventions. This paper provides the background and rationale of the technical consultation, synopsizes the presentations, and provides a summary of the main considerations proposed by the working groups. PMID- 30291628 TI - Historical weather data for climate risk assessment. AB - Weather- and climate-related hazards are responsible for monetary losses, material damages, and societal consequences. Quantifying related risks is, therefore, an important societal task, particularly in view of future climate change. For this task, climate risk assessment increasingly uses model chains, which mainly build on data from the last few decades. The past record of events could play a role in this context. New numerical techniques can make use of historical weather data to simulate impacts quantitatively. However, using historical data for model applications differs from using recent products. Here, we provide an overview of climate risk assessment methodologies and of the properties of historical instrumental and documentary data. Using three examples, we then outline how historical environmental data can be used today in climate risk assessment by (1) developing and validating numerical model chains, (2) providing a large statistical sample which can be directly exploited to estimate hazards and to model present risks, and (3) establishing "worst-case" events which are relevant references in the present or future. The examples show that, in order to be successful, different sources (reanalyses, digitized instrumental data, and documentary data) and methods (dynamical downscaling and analog methods) need to be combined on a case-by-case basis. PMID- 30291629 TI - Analysis of catalase mutants underscores the essential role of CATALASE2 for plant growth and day length-dependent oxidative signalling. AB - Three genes encode catalase in Arabidopsis. Although the role of CAT2 in photorespiration is well established, the importance of the different catalases in other processes is less clear. Analysis of cat1, cat2, cat3, cat1 cat2, and cat2 cat3 T-DNA mutants revealed that cat2 had the largest effect on activity in both roots and leaves. Root growth was inhibited in all cat2-containing lines, but this inhibition was prevented by growing plants at high CO2 , suggesting that it is mainly an indirect effect of stress at the leaf level. Analysis of double mutants suggested some overlap between CAT2 and CAT3 functions in leaves and CAT1 and CAT2 in seeds. When plants had been grown to a similar developmental stage in short days or long days, equal-time exposure to oxidative stress caused by genetic or pharmacological inhibition of catalase produced a much stronger induction of H2 O2 marker genes in short day plants. Together, our data (a) underline the importance of CAT2 in basal H2 O2 processing in Arabidopsis; (b) suggest that CAT1 and CAT3 are mainly "backup" or stress-specific enzymes; and (c) establish that day length-dependent responses to catalase deficiency are independent of the duration of oxidative stress. PMID- 30291630 TI - The IMF failure that wasn't: risk ignorance during the European debt crisis. AB - This article builds on ignorance studies to revisit how we understand the role of expertise in international policymaking. A fundamental component of ignorance is concealing what you know. For experts, risk ignorance is a strategic resource when the policymaking process becomes a contested exchange. This article covers IMF lending programmes in Europe in 2008-13 with a special focus on Greece. Empirical data is drawn from policy documents. I find that risk ignorance at the IMF resulted from a joint process of 'private alteration' and 'public obfuscation': the alteration of normal scenarios of debt sustainability in private negotiations worked in tandem with the obfuscation of programme risks in the public stage. The empirical contribution of this article is to show that the 'failure' of the IMF programme for Greece can be reconceptualized as 'success'. The immediate goal of the programme was to bailout Greece's creditors and avoid the breakup of European monetary institutions. In this respect, the programme was successful. But success came at a huge cost for Greece. Analytically, this article suggests that knowledge procurement based on empirical fact-gathering is not always the ultimate goal of international organizations and the communities of experts working within them. PMID- 30291632 TI - Seasonal changes in neuronal turnover in a forebrain nucleus in adult songbirds. AB - Neuronal death and replacement, or neuronal turnover, in the adult brain are one of many fundamental processes of neural plasticity. The adult avian song control circuit provides an excellent model for exploring mature neuronal death and replacement by new neurons. In the song control nucleus, HVC of adult male Gambel's white-crowned sparrows (Zonotrichia leucophrys gambelli) nearly 68,000 neurons are added each breeding season and die during the subsequent nonbreeding season. To accommodate large seasonal differences in HVC neuron number, the balance between neuronal addition and death in HVC must differ between seasons. To determine whether maintenance of new HVC neurons changes within and between breeding and nonbreeding conditions, we pulse-labeled two different cohorts of new HVC neurons under both conditions and quantified their maintenance. We show that the maintenance of new HVC neurons, as well as new nonneuronal cells, was higher at the onset of breeding conditions than at the onset of nonbreeding conditions. Once a steady-state HVC volume and neuronal number were attained in either breeding or nonbreeding conditions, neuronal and nonneuronal maintenance were similarly low. We found that new neuronal number correlated with a new nonneuronal number within each cohort of new neurons. Together, these data suggest that sex steroids promote the survival of an initial population of new neurons and nonneuronal cells entering HVC. However, once HVC is fully grown or regressed, neuronal and nonneuronal cell turnover is regulated by a common mechanism likely independent of direct sex steroid signaling. PMID- 30291633 TI - Neurostimulation for the treatment of chronic migraine and cluster headache. AB - Small subsets of patients who fail to respond to pharmacological treatment may benefit from alternative treatment methods. In the last decade, neurostimulation is being explored as a potential treatment option for the patients with chronic, severely disabling refractory primary headaches. To alleviate pain, specific nerves and brain areas have been stimulated, and various methods have been explored: deep brain stimulation, occipital nerve stimulation, and sphenopalatine ganglion stimulation are among the more invasive ones, whereas transcranial magnetic stimulation and supraorbital nerve stimulation are noninvasive. Vagal nerve stimulation can be invasive or noninvasive, though this review included only data for noninvasive VNS. Most of these methods have been tested in small open-label patient series; recently, more data from randomized, controlled, and blinded studies are available. Although neurostimulation treatments have demonstrated good efficacy in many studies, it still has not been established as a standard treatment in refractory patients. This review analyzes the available evidence regarding efficacy and safety of different neurostimulation modalities for the treatment of chronic migraine and cluster headache. PMID- 30291634 TI - Facebook use and sleep quality: Light interacts with socially induced alertness. AB - It has been demonstrated that the use of social networking sites late at night can lead to sleep-related problems that extend into the next day. A common explanation is that the light emitted from screens is disrupting the users' circadian rhythms. An alternative explanation is that the social cognition inherent in the use of social networking sites is responsible. Here, the two factors were looked at together. Participants used Facebook on iPad tablets before sleep. This was done on different nights with two lighting conditions and with two levels of content. In the 'light' condition, blue wavelength light was manipulated so that it was either full wavelength or blue light filtered. In the 'alertness' condition, the personal significance of the content was changed from personally relevant to irrelevant. A modified version of the Pittsburgh Sleep Quality Index was used to measure sleep-related problems. No evidence was found that simply filtering blue light or simply removing relevant content improved sleep quality. However, the two factors interacted. The results suggest that the light emitted from screens can affect sleep quality under some conditions but this is behaviourally irrelevant in the context of normal Facebook usage. PMID- 30291635 TI - Ice segregation in the crown of winter cereals: Evidence for extraorgan and extratissue freezing. AB - Meaningful improvements in winter cereal cold hardiness requires a complete model of freezing behaviour in the critical crown organ. Magnetic resonance microimaging diffusion-weighted experiments provided evidence that cold acclimation decreased water content and mobility in the vascular transition zone (VTZ) and the intermediate zone in rye (Secale cereale L. Hazlet) compared with wheat (Triticum aestivum L. Norstar). Differential thermal analysis, ice nucleation, and localization studies identified three distinct exothermic events. A high-temperature exotherm (-3 degrees C to -5 degrees C) corresponded with ice formation and high ice-nucleating activity in the leaf sheath encapsulating the crown. A midtemperature exotherm (-6 degrees C and -8 degrees C) corresponded with cavity ice formation in the VTZ but an absence of ice in the shoot apical meristem (SAM). A low-temperature exotherm corresponded with SAM injury and the killing temperature in wheat (-21 degrees C) and rye (-27 degrees C). The SAM had lower ice-nucleating activity and freezing survival compared with the VTZ when frozen in vitro. The intermediate zone was hypothesized to act as a barrier to ice growth into the SAM. Higher cold hardiness of rye compared with wheat was associated with higher VTZ and intermediate zone desiccation resulting in the formation of ice barriers surrounding the SAM. PMID- 30291636 TI - Electrodiagnostic evidence of suprascapular nerve recovery after decompression. AB - INTRODUCTION: The purpose of this study was to determine whether surgical arthroscopic decompression or ultrasound-guided aspiration of a paralabral cyst would result in suprascapular nerve recovery from axonal regeneration based on electrodiagnostic testing. METHODS: Nine patients with preoperative electromyography (EMG) evidence of suprascapular neuropathy due to paralabral cysts at the suprascapular or spinoglenoid notch were prospectively studied. Eight patients underwent arthroscopic surgical decompression, and 1 patient underwent ultrasound-guided aspiration. Postoperative EMG was performed in all patients to evaluate nerve regeneration. RESULTS: Three (33%) patients had cysts at the suprascapular notch, whereas 6 (67%) patients had cysts at the spinoglenoid notch. All patients showed complete electrophysiological recovery after decompression. DISCUSSION: Decompression of paralabral cysts at the suprascapular or spinoglenoid notch resulted in postoperative EMG evidence of nerve recovery. Long-term studies with a greater number of patients are required to elucidate time to recovery. Muscle Nerve, 2018.

AB - OBJECTIVES: Diarrhea is one of the most common and deadly conditions affecting children, causing over 525,000 deaths annually, largely in resource-limited settings. Appropriate treatment depends on accurate determination of dehydration status. This study evaluated the accuracy of a new model using clinical and ultrasound measurements for predicting dehydration status in children with acute diarrhea. METHODS: The Dehydration: Assessing Kids Accurately (DHAKA) study was a prospective cohort study of children under 5 years of age with acute diarrhea presenting to the International Centre for Diarrhoeal Disease Research in Dhaka, Bangladesh. Clinical signs and sonographic measurements of the aorta-to-inferior vena cava ratio were recorded. Percent weight change with rehydration was used to classify dehydration severity. Logistic regression was used to create a combined DHAKA-US model based on clinical and sonographic measurements. Area under the curve and calibration slope were used to assess the model's accuracy and compare it to the original DHAKA score model. RESULTS: A total of 850 children were enrolled, with 736 included in the final analysis. The combined DHAKA-US model showed equivalent discrimination with the original DHAKA score, with an area under the curve of 0.79 for both models for severe dehydration (95% confidence interval, 0.74-0.84), as well as similar classification (48% versus 50% correctly classified) and calibration (calibration slopes of 0.900 versus 0.904 for presence of any dehydration). CONCLUSION: Adding sonographic measurements to the DHAKA score had no effect on discrimination, classification, or calibration when compared to the original DHAKA score. Clinical signs alone may be the most important predictors of dehydration status in children with diarrhea in limited resource settings. PMID- 30291640 TI - Decision rule approach applied to estimate occupational lead exposure in a case control study of kidney cancer. AB - BACKGROUND: We developed a systematic, data-driven approach to estimate metrics of occupational exposure to lead to aid in epidemiologic analyses in a case control study of kidney cancer. METHODS: Probability of exposure to ten lead sources was assigned using decision rules developed from an extensive literature review and expert judgement. For jobs with >50% probability of exposure, we assigned source-specific frequency based on subjects' self-reported task frequencies or means of subjects' job-groups and source-specific intensity estimates of blood lead (MUg/dL). RESULTS: In our study, 18.7% of employed person years were associated with high (>=80%) probability of exposure to any lead source. The most common medium (>50%) or high probability source of lead exposure was leaded gasoline (2.5% and 11.5% of employed person-years, respectively). The median blood lead attributed to occupational exposure was 3.1 MUg/dL. CONCLUSIONS: These rules can aid in future studies after population-specific adaption for geographic differences and different exposure scenarios. PMID- 30291641 TI - Longitudinal and personalized networks of eating disorder cognitions and behaviors: Targets for precision intervention a proof of concept study. AB - INTRODUCTION: Despite the high mortality and significant societal and personal costs associated with eating disorders (EDs) there are few evidence-based treatments. Part of the difficulty developing and implementing evidence-based treatments in EDs is due to the extremely high heterogeneity (e.g., variability in treatment outcome, symptom presentation etc) present. METHODS: To begin to identify specific symptom heterogeneity within persons, the current study used novel within and between group and intra-individual network analyses to create longitudinal and within-person networks of ED cognitions and behaviors (N = 66 individuals diagnosed with an ED). This article provides a proof of concept study for how to use between and within-person network analyses both for the EDs and other forms of psychopathology. RESULTS: We found that cognitions focused on desiring thinness played a likely maintaining role in ED pathology, across network type and across time. Furthermore, we showed that three individuals with the same diagnosis (anorexia nervosa) differed in which symptoms maintained the disorder. We use these participants to exemplify how to use intra-individual network analysis to personalize treatment focused on the primary maintaining symptoms. Finally, we found that amount of time (e.g., 4 hr vs. simultaneously) impacts how symptoms maintain each other. CONCLUSIONS: These findings have implications for the development of novel personalized evidence-based treatments for EDs, as well as implications for how the field understands how psychopathology maintains itself. These data represent a first-step towards using intra-individual network analyses in the ED field, as well as for hypotheses generation in future research.

Prognostic pathological factors in radical cystectomy after neoadjuvant chemotherapy. Histopathology 2018; DOI: 10.1111/his.13654. AB - We read with interest the report by Brimo questioning the relevance of the Tumour Regression-Grade (TRG) after neo-adjuvant chemotherapy (NAC) and cystectomy in muscle-invasive bladder cancer (MIBC). While classical prognosticators such as T stage, N-stage and margin status were independent predictors of survival, TRG of the primary tumours (TRGPT ) failed to do so. However, the informative nature of the TRGPT may be impacted by the influence of trans-urethral resection in the primary tumour. This article is protected by copyright. All rights reserved.

AB - Apolipoprotein A-I (ApoA-I)-related amyloidosis is a rare disease caused by missense mutations in the APOA1 gene. These mutations lead to protein aggregation and abnormal accumulation of ApoA-I amyloid fibrils in heart, liver, kidneys, skin, nerves, ovaries, or testes. Consequently, the carriers are at risk of single- or multi-organ failure and of need of organ transplantation. Understanding the basic molecular structure and function of ApoA-I amyloidogenic variants, as well as their biological effects, is, therefore, of great interest. However, the intrinsic low stability of this type of proteins makes their overexpression and purification difficult. To overcome this barrier, we here describe an optimized production and purification procedure for human ApoA-I amyloidogenic proteins that efficiently provides between 46 mg and 91 mg (depending on the protein variant) of pure protein per liter of Escherichia coli culture. Structural integrity of the amyloidogenic and native ApoA-I proteins were verified by circular dichroism spectroscopy and intrinsic fluorescence analysis, and preserved functionality was demonstrated by use of a lipid clearance assay as well as by reconstitution of high-density lipoprotein (HDL) particles. In conclusion, the use of the described high-yield protein production system to obtain amyloidogenic ApoA-I proteins, and their native counterpart, will enable molecular and cellular experimental studies aimed to explain the molecular basis for this rare disease. PMID- 30291644 TI - Blood draws up to 3% of blood volume in clinical trials are safe in children. AB - AIM: Recommendations for maximum blood draw in children range from 1 to 5% despite limited evidence. The aim of the study was to assess the safety of blood draws in children aged six months to 12 years targeting volumes of 3% of total blood volume. METHODS: Children who experienced three-monthly blood draws during participation in one of three investigators initiated clinical trials conducted in our institution were examined. In total, 629 venous blood draws were performed in 141 children. Adverse events and blood counts were assessed. RESULTS: Overall, 608 adverse events were reported. None of these included symptoms that reflected concerns on blood draw volumes or frequency. Anaemia and red cell or haemoglobin measurements outside the normal age range were not observed. A reduction in haemoglobin, haematocrit, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration and mean corpuscular volume was noted in children participating in one of the three trials analysed. CONCLUSION: Regular blood draws of up to 3% of total blood volume were not associated with signs of anaemia or hypovolaemia in young children. We suggest that the European recommendations be revised for clinical studies in which children are not exposed to treatments that are associated with anaemia risk.

AB - The present study was conducted to explore the occurrence of Flavobacteriaceae in wild (n = 108) and farmed (n = 187) Nile Tilapia (Oreochromis niloticus) collected from Lake Victoria and twelve ponds in the Morogoro region, respectively. The size of the ponds surveyed ranged from 130 - 150 m2 . Ponds parameters and fish morphometric data were recorded during sampling. A total of 67 (farmed n = 44 and wild = 23) Flavobacterium-like isolates were identified on the basis of colony morphology and biochemical tests. Sequences from 16S rRNA gene revealed that all 67 isolates belonged to the genera Flavobacterium and Chryseobacterium. Based on 16S rRNA nucleotide identity, 26 isolates showed high similarity with Chryseobacterium indologenes (99 to 100% identity), 16 to Chryseobacterium joostei (98 - 99.9%), 17 to diverse species of Chryseobacterium (97 - 99%). Three isolates were each similar to Flavobacterium aquatile and Flavobacterium indicum with 99 - 100% nucleotide identity respectively and 2 isolates were similar to Flavobacterium oryzae (99 - 100%). The findings obtained in this study provide a baseline for future studies and contribute to an understanding of the threats presented by the aquatic Flavobacteriaceae reservoir towards the development of healthy fish farming in Tanzania. Such knowledge is vital for the development of sustainable aquaculture industry in Tanzania that will contribute to increased food security. This article is protected by copyright.

AB - The intrinsic redox activity of the dithiolene ligand is presented here as the novel spin host in the design of a prototype molecular electron spin qubit, where the traditional roles of the metal and ligand components in coordination complexes are inverted. A series of paramagnetic bis(dithiolene) complexes with group 10 metals-nickel, palladium, platinum-provides a backdrop to investigate the spin dynamics of the organic ligand radical using pulsed EPR spectroscopy. The temperature dependence of the phase memory time (TM ) is shown to be dependent on the identity of the diamagnetic metal ion, with the short times recorded for platinum a consequence of a diminishing spin-lattice (T1 ) relaxation time driven by spin-orbit coupling. The utility of the radical ligand spin center is confirmed when it delivers one of the longest phase memory times ever recorded for a molecular two-qubit prototype.

AB - PROBLEM: The role of vitamin D (VD) in IVF outcome and immune parameters has not been elucidated well. METHOD OF STUDY: Women undergoing IVF treatment with GnRH agonist (Agonist) and progestin-primed ovarian stimulation (PPOS) protocols were divided into VD lower (VDL, 25(OH)VD <=20 ng/mL) and VD higher (VDH, 25(OH)VD >20 ng/mL) groups. Follicular fluid (FF) VD level, IVF outcomes, and peripheral blood immunophenotypes by flow cytometry were analyzed. RESULTS: FF VD levels of the whole subjects were positively correlated with peripheral blood VD level (r = 0.86, P < 0.001). The number of mature oocytes and the blastocyst formation rate were significantly higher in women with VDH group as compared with those of VDL group in both Agonist and PPOS groups (P < 0.05, respectively). In women with PPOS protocol, peripheral blood NK and B-cell proportions and T helper/T cytotoxic (Th/Tc) cell ratios of VDL group were significantly higher than those of VDH group (P < 0.05, respectively). In women with Agonist protocol, peripheral blood B-cell proportion and Th/Tc ratios of VDL group were significantly higher than those of VDH group (P < 0.05, respectively). CONCLUSION: VD level is associated with IVF outcomes possibly derived by T-cell immunity, particularly Th/Tc ratios. PMID- 30291648 TI - Evaluation of Effects of TGF-beta1 Inhibition on Gastric Cancer in Nude Mice by Diffusion Kurtosis Imaging and In-Line X-ray Phase Contrast Imaging With Sequential Histology. AB - BACKGROUND: Accurate and complete response evaluation after treatment is important to implement individualized therapy for gastric cancer. PURPOSE: To investigate the effectiveness of diffusion kurtosis imaging (DKI) and in-line X ray phase contrast imaging (ILXPCI) in the assessment of the therapeutic efficacy by transforming growth factor beta 1 (TGF-beta1) inhibition. STUDY TYPE: Prospective animal study. ANIMAL MODEL: Thirty nude mice subcutaneous xenotransplantation tumor model of gastric cancer for DKI and 10 peritoneal metastasis nude mice model for ILXPCI. FIELD STRENGTH/SEQUENCE: Examinations before and serially at 7, 14, 21, and 28 days after TGF-beta1 inhibition treatment were performed at 3T MRI including T2 -weighted imaging (T2 WI) and DKI with five b values of 0, 500, 1000, 1500, 2000 s/mm2 ; ILXPCI examinations were performed at 14 days after treatment. ASSESSMENT: DKI parameters (apparent diffusion coefficient [ADC], diffusivity [D] and kurtosis [K]) were calculated by two experienced radiologists after postprocessing. STATISTICAL TESTS: For the differences in all the parameters between the baseline and each timepoint for both the treated and the control mice, the Mann-Whitney test was used. The Spearman correlation test was used to evaluate correlations among the DKI parameters and corresponding pathologic necrosis fraction (NF). RESULTS: ADC, D, and K values were significantly different between the two groups after treatment (P < 0.05). Serial measurements in the treated group showed that the ADC, D, and K values were significantly different at 7, 14, 21, and 28 days compared with baseline (P < 0.05). There were significant correlations between DKI parameters and NF (ADC, r = 0.865, P < 0.001; D, r = 0.802, P < 0.001; K, r = -0.944, P < 0.001). The ILXPCI results in the treated group showed a stronger absorption area than the control group. DATA CONCLUSION: DKI may be used to evaluate the complete course therapeutic effects of gastric cancer induced by TGF-beta1 inhibition, and the ILXPCI technique will improve the tumor microstructure resolution.

PMID- 30291649 TI - Prospective Evaluation of an R2* Method for Assessing Liver Iron Concentration (LIC) Against FerriScan: Derivation of the Calibration Curve and Characterization of the Nature and Source of Uncertainty in the Relationship. AB - BACKGROUND: FerriScan is the method-of-choice for noninvasive liver iron concentration (LIC) quantification. However, it has a number of drawbacks including cost and expediency. PURPOSE/HYPOTHESIS: To characterize an R2*-based MRI technique that may potentially be used as an alternative to FerriScan. This was accomplished through the derivation of a calibration curve that characterized the relationship between FerriScan-derived LIC and R2*. The nature and source of uncertainty in this curve were investigated. It was hypothesized that the source of uncertainty is heterogeneity of LIC across the liver. STUDY TYPE: Prospective. SUBJECTS: In all, 125 patients (69 women, 56 men) undergoing chelation treatment for iron overload prospectively underwent FerriScan and R2* MRI during the same exam. FIELD STRENGTH/SEQUENCE: Pulse sequences included 2D multislice spin-echo pulse for FerriScan, and a prototype 3D 6-echo gradient echo acquisition for R2* mapping at 1.5T. ASSESSMENT: A linear calibration curve was derived from the relationship between FerriScan-derived LIC estimates and R2* through least squares fitting. STATISTICAL TESTS: The nature of the uncertainty in the curve was characterized through tests of normality and homoscedasticity. The source of uncertainty was tested by comparing the magnitude of LIC variation over the FerriScan ROI to the observed uncertainty in the R2*-derived LIC estimates. RESULTS: A linear relationship between logarithmically transformed FerriScan derived LIC and R2* (log{FerriScan-derived LIC} = 1.029 log{R2*} - 3.822) was confirmed. Uncertainty was random, with a behaviour that was normal and homoscedastic. The source of uncertainty was confirmed as iron heterogeneity across the liver. The nontransformed calibration curve was: FerriScan-derived LIC = 0.0266?R2*, with a constant coefficient-of-variation of 0.32. DATA CONCLUSION: FerriScan and R2* techniques were found to provide equivalent quantification of LIC in this study. Any difference in accuracy or precision was at a level lower than the uncertainty caused by variation in LIC over the liver. LEVEL OF EVIDENCE: 1 Technical Efficacy: Stage 2 J. Magn. Reson.

AB - BACKGROUND: One of the primary biomechanical factors influencing arterial health is their deformation across the cardiac cycle, or cyclic strain, which is often associated with arterial stiffness. Deleterious changes in the cardiovascular system, e.g., increased arterial stiffness, can remain undetected until the system is challenged, such as under a cardiac stressor like dobutamine. PURPOSE: To quantify cyclic strain in mice at different locations along the arterial tree prior to and during dobutamine infusion, while evaluating the effects of sex and age. STUDY TYPE: Control/cohort study. ANIMAL MODEL: Twenty C57BL/6 mice; male, female; ~12 and 24 weeks of age; n = 5 per group. FIELD STRENGTH/SEQUENCE: 7T; CINE MRI with 12 frames, velocity compensation, and prospective cardiac gating. ASSESSMENT: Prior to and during the infusion of dobutamine, Green-Lagrange circumferential cyclic strain was calculated from perimeter measurements derived from CINE data acquired at the carotid artery, suprarenal and infrarenal abdominal aorta, and iliac artery. STATISTICAL TESTS: Analysis of variance (ANOVA) followed by post-hoc tests was used to evaluate the influence of dobutamine, anatomical location, sex, and age. RESULTS: Heart rates did not differ between groups prior to or during dobutamine infusion (P = 0.87 and P = 0.08, respectively). Dobutamine increased cyclic strain in each group. Within a group, increases in strain were similar across arteries. At the suprarenal aorta, strain was reduced in older mice at baseline (young 27.6 > mature 19.3%, P = 0.01) and during dobutamine infusion (young 53.0 > mature 36.2%, P = 0.005). In the infrarenal aorta, the response (dobutamine - baseline) was reduced in older mice (young 21.9 > mature 13.5%, P = 0.04). DATA CONCLUSION: Dobutamine infusion increases circumferential cyclic strain throughout the arterial tree of mice. This effect is quantifiable using CINE MRI. The results demonstrate that strain prior to and during dobutamine is influenced by anatomical location, sex, and age. LEVEL OF EVIDENCE: 3 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2018. PMID- 30291651 TI - Increased iron deposition of deep cerebral gray matter structures in hemodialysis patients: A longitudinal study using quantitative susceptibility mapping. AB - BACKGROUND: The cerebral iron overload in hemodialysis patients has been reported in a previous study, in which the evaluation of the changes in iron content could be affected by the cross-sectional analysis. PURPOSE: To investigate the longitudinal changes of iron deposition in hemodialysis patients using quantitative susceptibility mapping (QSM) and correlate these findings with the longitudinal changes of neurocognitive function and clinical factors. STUDY TYPE: Prospective; longitudinal. POPULATION: In all, 34 patients and 30 healthy controls (HCs); the mean follow-up interval was 22 +/- 7 months. FIELD STRENGTH/SEQUENCE: 3.0T, susceptibility-weighted imaging (SWI). ASSESSMENT: QSM reconstructed from original phase data of SWI was used to measure the susceptibility of gray matter structures including bilateral caudate nucleus (CN), globus pallidus (GP), putmen (PUT), red nucleus (RN), substantia nigra (SN), dentate nucleus (DN), thalamus (THA), pulvinar of thalamus (PT). The Mini Mental State Examination (MMSE) test and clinical factors were recorded. STATISTICAL TESTING: Analysis of covariance adjusting for age and gender as covariates or a paired t-test for the differences in susceptibility, MMSE scores, and clinical factors among baseline, follow-up patients, and HCs. Correlation and stepwise regression analysis for the relationship between susceptibility, MMSE scores, and clinical factors. RESULTS: The susceptibility of bilateral CN, GP, PUT, RN, SN, DN, THA, PT in follow-up patients was significantly higher than that in baseline between patients and HCs except for left THA (all P < 0.05; Bonferroni corrected). MMSE scores significantly negatively correlated with the susceptibility of bilateral CN, PUT, and RRN in the baseline examination and bilateral CN, PUT, RN, and DN in the follow-up examination (all P < 0.05; false discovery rate [FDR] corrected). The follow-up interval, creatinine, phosphorus, and calcium were independent factors for the increased susceptibility of some nuclei (all P < 0.05). DATA CONCLUSION: The iron deposition of gray matter nuclei in hemodialysis patients increased over roughly a 2-year period and may be a risk factor for neurocognitive impairment. Creatinine and abnormal calcium-phosphorus metabolism were independent risk factors for abnormal iron deposition. LEVEL OF EVIDENCE: 2 Technical Efficacy: Stage 1 J. Magn. Reson. Imaging 2018. PMID- 30291652 TI - Quantitative MRI of Visually Intact Rotator Cuff Muscles by Multiecho Dixon-Based Fat Quantification and Diffusion Tensor Imaging. AB - BACKGROUND: Quantitative MRI allows assessment of shoulder rotator cuff (RC) muscles by Dixon MR sequences with calculation of fractional fat content (FF%) maps and diffusion tensor imaging (DTI) including tractography. PURPOSE: To compare FF% and DTI derived parameters among visually intact RC muscles, to compare 2D with 3D DTI measurements and to establish normative values. STUDY TYPE: Prospective. SUBJECTS: Forty patients aged >18 years undergoing shoulder MR arthrography were included. FIELD STRENGTH/SEQUENCE: MR arthrography of the shoulder including 3D multiecho Dixon and 3D echo-planar DTI sequences (15 gradient encoding directions, b-value 600 s/mm2 ) was performed at 3.0T. ASSESSMENT: Muscles affected by RC tears or fatty infiltration of Goutallier grade >=1 were excluded. Two independent radiologists measured FF%, apparent diffusion coefficient (ADC), and fractional anisotropy (FA) by region-of-interest (ROI) placements at the Y-position of the scapula and 3D tractography of each muscle with qualitative evaluation was performed. STATISTICAL TESTS: Intraclass correlation coefficients (ICCs) and Cohen's kappa were used for interreader agreement and Pearson correlation coefficient to correlate quantitative measures with each other and age, independent-samples t-test, one-way analysis of variance (ANOVA), and Kruskal-Wallis test were performed to investigate differences between genders and muscles. RESULTS: Qualitative and quantitative measurements showed moderate (kappa = 0.41-0.56) to almost perfect (ICC = 0.75-0.99) agreement. There were weak but significant positive correlations of FF% with age (r = 0.273, P < 0.05) and FA-2D (r = 0.319-0.383, P < 0.05). Significant differences were found among RC muscles for ADC, radial diffusivity (RD), and tract homogeneity (all P < 0.05) but not between genders (all P >= 0.05). High correlations of 2D with 3D measurements for ADC (r = 0.639, P < 0.001) and FA (r = 0.628, P < 0.001) were seen. DATA CONCLUSION: Quantitative MRI with estimation of FF% and DTI parameters shows significant age-associated changes and differences among visually intact RC muscles. High reproducibility and correlations of 2D with 3D DTI measurements can be expected. LEVEL OF EVIDENCE: 2 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2018.

PMID- 30291654 TI - Absolute Quantification of Phosphor-Containing Metabolites in the Liver Using 31 P MRSI and Hepatic Lipid Volume Correction at 7T Suggests No Dependence on Body Mass Index or Age. AB - BACKGROUND: Hepatic disorders are often associated with changes in the concentration of phosphorus-31 (31 P) metabolites. Absolute quantification offers a way to assess those metabolites directly but introduces obstacles, especially at higher field strengths (B0 >= 7T). PURPOSE: To introduce a feasible method for in vivo absolute quantification of hepatic 31 P metabolites and assess its clinical value by probing differences related to volunteers' age and body mass index (BMI). STUDY TYPE: Prospective cohort. SUBJECTS/PHANTOMS: Four healthy volunteers included in the reproducibility study and 19 healthy subjects arranged into three subgroups according to BMI and age. Phantoms containing 31 P solution for correction and validation. FIELD STRENGTH/SEQUENCE: Phase-encoded 3D pulse acquire chemical shift imaging for 31 P and single-volume 1 H spectroscopy to assess the hepatocellular lipid content at 7T. ASSESSMENT: A phantom replacement method was used. Spectra located in the liver with sufficient signal-to-noise ratio and no contamination from muscle tissue, were used to calculate following metabolite concentrations: adenosine triphosphates (gamma- and alpha-ATP); glycerophosphocholine (GPC); glycerophosphoethanolamine (GPE); inorganic phosphate (Pi ); phosphocholine (PC); phosphoethanolamine (PE); uridine diphosphate-glucose (UDPG); nicotinamide adenine dinucleotide-phosphate (NADH); and phosphatidylcholine (PtdC). Correction for hepatic lipid volume fraction (HLVF) was performed. STATISTICAL TESTS: Differences assessed by analysis of variance with Bonferroni correction for multiple comparison and with a Student's t-test when appropriate. RESULTS: The concentrations for the young lean group corrected for HLVF were 2.56 +/- 0.10 mM for gamma-ATP (mean +/- standard deviation), alpha-ATP: 2.42 +/- 0.15 mM, GPC: 3.31 +/- 0.27 mM, GPE: 3.38 +/- 0.87 mM, Pi : 1.42 +/- 0.20 mM, PC: 1.47 +/- 0.24 mM, PE: 1.61 +/- 0.20 mM, UDPG: 0.74 +/- 0.17 mM, NADH: 1.21 +/- 0.38 mM, and PtdC: 0.43 +/- 0.10 mM. Differences found in ATP levels between lean and overweight volunteers vanished after HLVF correction. DATA CONCLUSION: Exploiting the excellent spectral resolution at 7T and using the phantom replacement method, we were able to quantify up to 10 31 P containing hepatic metabolites. The combination of 31 P magnetic resonance spectroscopy imaging data acquisition and HLVF correction was not able to show a possible dependence of 31 P metabolite concentrations on BMI or age, in the small healthy population used in this study.

PMID- 30291655 TI - Disrupted functional connectivity and activity in the white matter of the sensorimotor system in patients with pontine strokes. AB - BACKGROUND: White matter (WM) blood oxygenation level-dependent (BOLD) signals are reported to be related to neural activity. However, sensitivity of WM BOLD signals to disease remains unclear. PURPOSE: To investigate WM BOLD signal changes, directional variations of resting-state correlations in sensorimotor system in patients with pontine strokes, and to determine the relationship between WM BOLD signals and motor deficits. STUDY TYPE: Prospective. SUBJECTS: Ethical approval was obtained from the local Ethics Committee and each participant gave written informed consent. Sixteen patients with focal pontine lesions and 16 age-matched control subjects were included. FIELD STRENGTH/SEQUENCE: 3.0T T1 -weighted anatomic images using a 3D magnetization prepared rapid gradient-echo sequence. Resting-state fMRI images using gradient echo echo-planar imaging sequence. Diffusion-weighted images using single-shot spin-echo diffusion echo-planar imaging. ASSESSMENT: Relevant WM tracts in the sensorimotor system by region of interest-wise analysis were identified. Power spectra of BOLD signals and anisotropy of resting-state correlations were measured in sensorimotor system and compared between two groups. Their relationships with clinical scores were analyzed. STATISTICAL TESTS: Two-sample t test; partial correlation analysis. RESULTS: Power spectra of BOLD signals in nerve tracts on the ipsilesional side were significantly decreased (P < 0.05). Compared with that in healthy subjects, the anisotropy of resting-state correlations along identified WM tracts was decreased in the thalamus dorsolateral prefrontal cortex bundle on the contralesional side, and all nerve tracts on the ipsilesional side. Partial least squares regression analysis showed the predicted outcome scores correlated significantly with actual Fugl-Meyer scores (R2 = 0.944, P = 0.013). DATA CONCLUSION: Our findings suggest that disrupted activity and functional connectivity in WM areas of the sensorimotor system can be detected in pontine strokes, and may serve as a biomarker for motor function prediction.

AB - : Positron emission tomography / magnetic resonance imaging (PET/MRI) is an emerging imaging technology that allows for the acquisition of multiple MRI parameters simultaneously with PET data. In this review, we address the technical requirements of PET/MRI including protocols and tracers, the potential of integrated localized breast PET/MRI exams, and possible applications of whole body PET/MRI in breast cancer patients. Currently, PET/MRI can be performed on sequential and integrated PET/MRI scanners but, as not all practices can access these dedicated machines, several studies look at PET and MRI exams that are performed separately on separate scanners within a short time frame. This practice likely provides similar clinical data, although exact colocalization for iso-voxel analysis, currently performed only in research, is not possible. In PET/MRI, the MRI sequences are flexible and can be customized according to the aim of the exam. The most commonly used radiotracer is 18 F-FDG; however, tracers that image hypoxia and drug targets such as estrogen receptors and HER2 are in development and may increase the utility of PET/MRI. For dedicated breast PET/MRI, a potential advantage over standard breast MRI alone may be the complementary sensitivities of MRI for extent of disease within the breast and PET for axillary and internal mammary nodal metastases. Moreover, layers of multiparametric MRI and PET metrics derived from the index lesion are being investigated as predictors of response to neoadjuvant therapy. These data may eventually be able to be quantified and mined in a way that furthers radiomics and also precision medicine. Finally, in whole-body imaging of breast cancer patients, single-institution studies have found that PET/MRI detects more metastases than PET at about half the radiation dose, although a survival benefit has not been shown. For now, whole-body PET/MRI in breast cancer patients may be most relevant for young patients who may undergo serial surveillance exams. LEVEL OF EVIDENCE: 3 Technical Efficacy: Stage 2 J. Magn.

AB - Life history traits differ between organisms living in the tropics, Northern and Southern Hemispheres, and sexual selection is thought to be stronger close to the equator than in temperate regions. Although birds are often supposed to be more brightly coloured in the tropics, the current evidence of geographic variation in the intensity of sexual selection and sex-specific natural selection is equivocal. Whether sex-specific traits signal aspects of individual quality better in the tropics than in the temperate regions of the Northern and Southern Hemispheres therefore remains an open question. We examined predictions of this hypothesis in the Tytonidae family (barn owls and their relatives) because females, on average, display larger black spots on the tip of their ventral body feathers than males, and this trait is associated with aspects of individual quality. We measured the size of melanic spots and the wing length of 7893 Tytonidae skins collected worldwide and preserved in natural history museums. The covariation between spot size and wing length was stronger in females than in males, in large- than small-spotted Tyto taxa and close to the equator than in temperate regions. This suggests that selection for spot size, which can be used by owls as an additional cue to assess individual body size and other aspects of phenotypic quality, is stronger in females than in males, particularly near the equator.

AB - In situ surface-enhanced Raman spectra of the headspace above cultures of six bacterial species showed strong characteristic bands from chemisorbed methyl sulfide. This marker compound is created by dissociation of dimethyl disulfide (DMDS), a fermentative metabolite of bacteria, on the surface of the enhancing Au or Ag nanoparticle films. Kinetic binding plots of media spiked with DMDS and of live cultures showed that the Au-based substrates were more suitable for the rapid detection of bacteria than Ag-based substrates. For E. coli DH5alpha, the sensitivity limit for headspace SERS detection was 1.5*107 CFU mL-1 , which corresponded to detection 15 min after inoculation of the growth medium. Since the metabolites are only produced by viable bacteria, antibiotic (gentamicin) treatment stopped the normal signal growth of the marker peak. This work is a promising step towards rapid bedside detection of bacterial infections and rapid screening of antibiotics against bacteria.

AB - In the presence of trifluoroacetic acid, on the basis of three-component condensation of phenylthiourea with its salicylaldehyde and methyl-3 oxobutanoate, an efficient method for the synthesis of 1-(4-(2-hydroxyphenyl)-6 methyl-1-phenyl-2-thioxo-1,2,3,4-tetrahydropyrimidin-5-yl)ethanone (I) has been worked out. These novel N-substituted tetrahydropyrimidines based on phenylthiourea showed good inhibitory action against acetylcholinesterase (AChE), alpha-glycosidase, and human carbonic anhydrase (hCA) isoforms I and II. K i values of AChE enzyme were in the range of 0.48 to 7.46 nM. The hCA I and II were effectively inhibited by the compounds, with K i values in the range of 502.44 to 923.11 nM for hCA I and 400.32 to 801.57 nM for hCA II, respectively. The antioxidant activity of the novel N-substituted tetrahydropyrimidines based on phenylthiourea was investigated by using different in vitro antioxidant assays; including 1,1-diphenyl-2-picrylhydrazyl (DPPH.) radical scavenging, Cu 2+ and Fe 3+ reducing activities.

AB - Differentiated cells telomere length is an indicator of senescence or lifespan; however, in peripheral blood leukocytes the relative shortening of the telomere has been considered as a biological marker of aging, and lengthening telomere as an associated risk to cancer. Individual's age, type of tissue, lifestyle, and environmental factors make telomere length variable. The presence of environmental carcinogens such as arsenic (As) influence as causal agents of these alterations, the main modes of action for As described are oxidative stress, reduction in DNA repair capacity, overexpression of genes, alteration of telomerase activity, and damage to telomeres. The telomeres of leukocytes resulting a finite capacity of replication due to the low or no activity of the telomerase enzyme, therefore, elongation telomere in this kind of cells is a potential biological marker associated with the development of chronic diseases and carcinogenesis.

We describe the case of a 37-year-old woman with a 2 years history of macerated erythematous plaques along with erosions, fissures, and crusts located on axillae and submammary areas, successfully treated with only oral supplementation of vitamin D (800 I.U./die) for 3 months. We reported this case to suggest that oral vitamin D may be enumerated in the various treatments proposed for HHD so far due to its rapid efficacy on skin lesions and symptoms.

AB - The union of photoredox and nickel catalysis has resulted in a renaissance in radical chemistry as well as in the use of nickel-catalyzed transformations, specifically for carbon-carbon bond formation. Collectively, these advances address the longstanding challenge of late-stage cross-coupling of functionalized alkyl fragments. Empowered by the notion that photocatalytically-generated alkyl radicals readily undergo capture by Ni complexes, wholly new feedstocks for cross coupling have been realized. Herein, we highlight recent developments in several types of alkyl cross-couplings that are accessible exclusively through this approach.

PMID- 30291663 TI - Phytochemical screening and antityrosinase activity of carvacrol, thymoquinone, and four essential oils of Lebanese plants. AB - OBJECTIVE: In our study, we aim to explore the ability of four essential oils (EO) of Lebanese plants to inhibit the tyrosinase activity and to correlate their efficiency level to their phytochemical compositions. METHODS: The EO have been extracted by hydrodistillation using a Clevenger apparatus and have been studied by GC-MS analysis. Active compounds of Origanum species were identified and antityrosinase activities of EO and active molecules (carvacrol and thymoquinone) have been tested in tubo. RESULTS: Antityrosinase activities were obtained as follows: EO of Origanum syriacum (80.41% +/- 2.00%), EO of Origanum ehrenbergii (45.33% +/- 2.20%), EO of Salvia fruticosa (14.62% +/- 2.30%), EO of Calamintha origanifolia (16.51% +/- 5.80%), Carvacrol (56.55% +/- 3.10%), and Thymoquinone (19.49% +/- 1.50%). CONCLUSION: Origanum essential oils resulted in the highest antityrosinase activity due to their high content in carvacrol. However, when present together with carvacrol, thymoquinone decreases the efficiency of carvacrol, which is the case of O. ehrenbergii essential oil. Thus, for improved antityrosinase activity, O. syriacum and O. ehrenbergii should be harvested during flowering stage where carvacrol is present at its highest dosage and thymoquinone at its lowest. PMID- 30291666 TI - Enantioselective synthesis of enantiopure chiral alcohols using carbonyl reductases screened from Yarrowia lipolytica. AB - AIMS: We aimed to explore Yarrowia lipolytica carbonyl reductases as effective biocatalysts and to develop efficient asymmetric reduction systems for chiral alcohol synthesis. METHODS AND RESULTS: Yarrowia lipolytica carbonyl reductase genes were obtained via homologous sequence amplification strategy. Two carbonyl reductases, YaCRI and YaCRII, were identified and characterized, and used to catalyse the conversion of 2-hydroxyacetophenone (2-HAP) to optically pure (S)-1 phenyl-1,2-ethanediol. Enzymatic assays revealed that YaCRI and YaCRII exhibited specific activities of 6.96 U mg-1 (99.8% e.e.) and 7.85 U mg-1 (99.9% e.e.), respectively, and showed moderate heat resistance at 40-50 degrees C and acid tolerance at pH 5.0-6.0. An efficient whole-cell two-phase system was established using reductase-expressing recombinant Escherichia coli. The conversion of 2-HAP (20.0 g l-1 ) conversion with the solvent of dibutyl phthalate was approximately 70-fold higher than in water. Furthermore, the two recombinant E. coli displayed biocatalyst activity and enantioselectivity towards several different carbonyl compounds, and E. coli BL21 (DE3)/pET-28a-yacrII showed a broad substrate spectrum. CONCLUSIONS: A new whole-cell recombinant E. coli-based bioreduction system for enantiopure alcohol synthesis with high enantioselectivity at high substrate concentrations was developed. SIGNIFICANCE AND IMPACT OF THE STUDY: We proposed a promising approach for the efficient preparation of enantiopure chiral alcohols. PMID- 30291667 TI - Synthesis of BCP Benzylamines From 2-Azaallyl Anions and [1.1.1]Propellane. AB - For bioactive molecules, bicyclo[1.1.1]pentanes (BCPs) are an emerging isostere of rigid spacer groups that have shown potential to improve drug-like qualities. As BCPs become an increasingly popular motif for evaluation in drug candidates, organic chemists must meet the demand to reliably incorporate them into new targets. To provide access to BCP analogues of diaryl methanamines, a ubiquitous scaffold in medicinal chemistry, we report the synthesis of BCP benzylamines through reactivity of [1.1.1]propellane with 2-azaallyl anions, which are generated in situ from N-benzyl ketimines. The reaction proceeds rapidly at room temperature and tolerates a broad substrate scope, providing straightforward access to 23 new BCP benzylamine derivatives. Initial experiments support the intermediacy of a BCP anion. Additionally, the reaction can be promoted by substoichiometric loadings of base, highlighting an unusual reactivity of both 2 azaallyls and [1.1.1]propellane.

However, the distribution pattern remains incompletely understood. Various examples show that very closely related species display different regenerative capacities. Why and how have diverse regenerative capacities evolved across species? One prevailing thought in the field of regeneration is that most regeneration associated factors are evolutionarily conserved, suggesting the existence of an innate tissue regeneration ability in all species. However, its regulation is differentially controlled in distinct species, resulting in heterogeneous regenerative capabilities. In this review, we discuss regeneration-associated enhancers, the key cis-regulatory elements controlling gene expression, their underlying molecular mechanisms, and their influence on regenerative capacity. Understanding the regulatory mechanisms of regeneration enhancers can provide fundamental insights into tissue regeneration and further help us develop therapeutic strategies to unlock latent healing powers in humans.

PMID- 30291669 TI - Application of the MADS classification system in a "mega mammoth" stent trial: Feasibility and preliminary clinical implications. AB - OBJECTIVES AND BACKGROUND: We attempted to test the feasibility of application of the MADS classification system in the largest stent trial to date and evaluate the preliminary clinical implications of this approach. METHODS: In the randomized GLOBAL LEADERS trial, testing two different antiplatelet strategies in patients undergoing PCI with bivalirudin and biolimus-eluting stents, the e-CRF was dedicated to bifurcation treatment according to the MADS classification. Based on this e-CRF, the techniques used for bifurcations treatment in GLOBAL LEADERS were described and compared with two large, all-comer registries of bifurcations treatment (I-BIGIS and COBIS), used as historical controls. RESULTS: Among 15,991 patients enrolled in the trial, 22,921 lesions treated at the index and staged procedure were available for analysis and 2,757 of these lesions were bifurcations and 7 were trifurcation lesions. The e-CRF-based MADS classification was achieved in 2,757 of these lesions (100%). 80.3% of bifurcations were treated using a single stent, 18.9% using 2 stents and 0.7% using 3 stents. Overall, the "main across side first" approach (A) was used in 77.4% with the "side branch first" approach (S) being the second most frequently used technique (10.2%). A single stent was used in the majority of the "A" approach (87.9%). A reduction in the use of 2-stent techniques (from 33.9 to 18.9%) was observed between GLOBAL LEADERS and I-BIGIS. The "A" approach was the most frequently used technique in GLOBAL LEADERS, while in COBIS the "S" strategy was most frequently employed. CONCLUSIONS: Application of the MADS classification through an e-CRF was feasible in the largest stent trial today and provided useful information about the trends observed overtime in the treatment of bifurcation lesions. PMID- 30291670 TI - Use of a novel 589-nm solid-state laser for treatment of facial erythema. AB - OBJECTIVE: To evaluate the efficacy and safety associated with use of a 589-nm solid-state laser for treatment of facial erythema. METHODS: A prospective, IRB approved study was conducted. Participants who were interested in treatment for facial erythema were recruited. They received four monthly treatments with the 589-nm laser. Erythema of the right and left face was graded on a scale of 0-4, 4 being most severe, by both investigators and participants prior to each treatment and at follow-up. Safety was assessed by any reported side effects. RESULTS: Twenty-four participants enrolled in the study, 16 women (67%) and 8 men (33%), with an average age of 51.1 years. Investigator grades showed a statistically significant improvement in erythema of 31% for both the right and left face. Participant grades showed a statistically significant improvement in erythema of 23.2% for the right face and 22.8% for the left face. Side effects were limited to transient erythema posttreatment. CONCLUSION: A 589-nm solid-state laser achieved a modest improvement in facial erythema when evaluating results 1 month after four monthly treatments. No major safety issues were reported. PMID- 30291671 TI - Highly Enantiospecific Borylation for Chiral alpha-Amino Tertiary Boronic Esters. AB - Herein we report a highly efficient and enantiospecific borylation method to synthesize a wide range of enantiopure (>99 % ee) alpha-amino tertiary boronic esters. The configurationally stable alpha-N-Boc substituted tertiary organolithium species and pinacolborane (HBpin) underwent enantiospecific borylation at -78 degrees C with the formation of a new stereogenic C-B bond. This reaction has a broad scope, enabling the synthesis of various alpha-amino tertiary boronic esters in excellent yields and, importantly, with universally excellent enantiospecificity (>99 % es) and complete retention of configuration. PMID- 30291672 TI - Sustained Virological Response Is Associated with a Decreased Risk of Posttransplant Diabetes Mellitus in Liver Transplant Recipients with Hepatitis C Related Liver Disease. AB - Posttransplant diabetes mellitus (PTDM), an increasingly recognized complication of solid organ transplantation, is associated with increased morbidity and mortality following liver transplantation (LT). Hepatitis C virus (HCV) infection is a consistent and modifiable risk factor for PTDM. Prior studies have demonstrated improvement in glucose metabolism following sustained virological response (SVR). However, the effect of SVR on the incidence of PTDM has not been previously investigated in a large cohort of LT recipients. We performed a single center retrospective cohort study of LT recipients with HCV from January 1, 2010 to June 30, 2015 to compare the risk of sustained posttransplant diabetes mellitus (s-PTDM) prior to and following SVR. SVR was treated as a discrete time varying exposure. The s-PTDM was defined as de novo diabetes mellitus following LT of a >6-month duration. Univariate and multivariate Cox proportional hazards models were used to compare crude and adjusted time to s-PTDM prior to and following SVR. There were 256 eligible LT recipients analyzed. Median follow-up was 41.2 months. Overall, 31 (12.1%) and 178 (69.5%) patients achieved SVR prior to LT and following LT, respectively. During follow-up, 71 (27.7%) patients developed s-PTDM. The incidence of s-PTDM was greatest in the first year after LT. After adjustment for potential confounders, SVR was associated with a significantly reduced risk of s-PTDM (HR, 0.40; P = 0.048). In conclusion, eradication of HCV is independently associated with a reduced incidence of s PTDM. This benefit appears to be most influenced by pre-LT SVR and persists throughout the post-LT period. Given the association between PTDM and posttransplant morbidity and mortality, these data provide another motivator for pre-LT or early post-LT treatment of HCV. PMID- 30291673 TI - Impact of face proportions on face attractiveness. AB - BACKGROUND: Proportions of face components appear to play a role in facial attractiveness. AIMS: The aim of the study was to establish the best proportions of face components in relation to whole face shape for facial attractiveness. METHODS: Only one face component (eye, nose, or lips) of a model in a series of photographs was altered using a computer program. Alterations consisted of size reduction or augmentation by 5% or 10%. Each photograph depicted a particular face component altered to either 90%, 95%, 100%, 105%, or 110% of its original size. Collages of photographs were shown to 167 individuals (male and female) for a fixed period of 7 seconds. Their task was to indicate the most attractive photograph of a model in a presented collage. RESULTS: In total, 48.1% of individuals preferred enhanced eyes both in males and females. We found that the preferred mean eye size in women was statistically significantly higher than that in men. In total, 64.8% of respondents preferred reduced nose proportions in women (27.5% found a reduction to 90% of the original size more attractive while 37.3% preferred a reduction to 95%). It was demonstrated that the preferred mean nose size was statistically significantly lower in females in comparison with males. Respondents expressed a greater preference for nose reduction in women in comparison with men. 38.4% of respondents (in regard to both male and female mouth) preferred reduced mouth. 40.7% of respondents preferred reduced mouth in the female model. CONCLUSIONS: Our work delivers statistically significant evidence that facial attractiveness increases together with the enlargement of the uncovered eye surface as well as the reduction in nose and lip size. Data were obtained using modern collective intelligence methods of validation. Written consent was obtained from all study participants. PMID- 30291674 TI - Luminescent Thermometry by a Y/Eu Binary Layered Rare-Earth Hydroxide (LRH) via In Situ Intercalation with Neutral Terbium(III) Complexes. AB - Temperature-sensitive luminescent materials have aroused great interest for practical applications in optical sensors. Layered rare-earth hydroxides (LRHs) possess rich interlayer chemistry and adjustable composition; thus, they are the promising candidates for designing functional materials, usually through an ion exchange process. Herein, the intercalation of neutral TbIII complex rather than ion exchange was successfully performed in situ into the gallery of Y/Eu binary LRHs by using a hydrothermal process. Interestingly, the swollen LRHs are chameleon luminophores, exhibiting color emissions from green to pink that were tunable through variations in temperature ranging from 77 to 450 K. Because of the highly sensitive and temperature-dependent emissions, novel optical temperature sensors for 1D and 2D thermal imaging were fabricated by employing the chameleon luminophores, which displayed luminescence capable of reversibly undergoing repeated thermocycles. The present work opens up new fields in layered inorganic materials. PMID- 30291677 TI - Marc Verstraete (1925-2018). PMID- 30291675 TI - Adenosine deaminase inhibition suppresses progression of 4T1 murine breast cancer by adenosine receptor-dependent mechanisms. AB - The activity of a cell-surface ecto-adenosine deaminase (eADA) is markedly increased in the endothelial activation and vascular inflammation leading to decreased adenosine concentration and alterations in adenosine signalling. Depending on the specific pathway activated, extracellular purines mediate host cell response or regulate growth and cytotoxicity on tumour cells. The aim of this study was to test the effects of adenosine deaminase inhibition by 2'deoxycoformycin (dCF) on the breast cancer development. dCF treatment decreased a tumour growth and a final tumour mass in female BALB/c mice injected orthotopically with 4T1 cancer cells. dCF also counteracted cancer-induced endothelial dysfunction in orthotopic and intravenous 4T1 mouse breast cancer models. In turn, this low dCF dose had a minor effect on immune stimulation exerted by 4T1 cell implantation. In vitro studies revealed that dCF suppressed migration and invasion of 4T1 cells via A2a and A3 adenosine receptor activation as well as 4T1 cell adhesion and transmigration through the endothelial cell layer via A2a receptor stimulation. Similar effects of dCF were observed in human breast cancer cells. Moreover, dCF improved a barrier function of endothelial cells decreasing its permeability. This study highlights beneficial effects of adenosine deaminase inhibition on breast cancer development. The inhibition of adenosine deaminase activity by dCF reduced tumour size that was closely related to the decreased aggressiveness of tumour cells by adenosine receptor-dependent mechanisms and endothelial protection. PMID- 30291676 TI - Dual functions of ARP101 in targeting membrane type-1 matrix metalloproteinase: Impact on U87 glioblastoma cell invasion and autophagy signaling. AB - Membrane type-1 matrix metalloproteinase (MT1-MMP) possesses both extracellular proteolytic and intracellular signal-transducing functions in tumorigenesis. An imbalance in MT1-MMP expression and/or function triggers a metastatic, invasive, and therapy resistance phenotype. MT1-MMP is involved in extracellular matrix (ECM) proteolysis, activation of latent MMPs, as well as in autophagy signaling in human hepatoma and glioblastoma cells. A low autophagy index in tumorigenesis has been inferred by recent studies where autophagic capacity was decreased during tumor progression. Here, we establish ARP101 as a dual-function small molecule inhibitor against MT1-MMP ECM hydrolysis and autophagy signal transducing functions in a model of grade IV glioblastoma cells. ARP101 inhibited concanavalin-A-mediated proMMP-2 activation into MMP-2, as well as MT1-MMP auto proteolytic processing. When overexpressing recombinant Wt MT1-MMP, ARP101 inhibited proMMP-2 activation and triggered the formation of MT1-MMP oligomers that required trafficking to the plasma membrane. ARP101 further induced cell autophagy as reflected by increased formation of acidic vacuole organelles, LC3 puncta, and autophagy-related protein ATG9 transcription. These were all significantly reversed upon siRNA-mediated gene silencing of MT1-MMP. ARP101 can thus concomitantly inhibit MT1-MMP extracellular catalytic function and exploit its intracellular transducing signal function to trigger autophagy-mediated cell death in U87 glioblastoma cancer cells. PMID- 30291678 TI - Gender and age differences in outcomes of patients with acute coronary syndromes referred for coronary angiography. AB - OBJECTIVES: The number of elderly patients undergoing coronary revascularization is steadily increasing, and data on the impact of gender on outcomes are scarce. This study sought to assess gender-related differences in outcomes in elderly patients with acute coronary syndromes (ACS). METHODS: We investigated outcomes in elderly ACS patients referred for coronary angiography and prospectively enrolled in the Swiss ACS Cohort between December 2009 and October 2012. Adjudicated major adverse cardiovascular and cerebrovascular events (MACCE) included all-cause death, non-fatal myocardial infarction, clinically indicated repeat coronary revascularization, definite stent thrombosis, and transient ischemic attack/stroke. RESULTS: Among 2,168 patients recruited, 481 (22%) patients were >75 years of age (37% women). In patients >75 years, 1-year MACCE rates were 15% and 23% in women and men (OR 0.59, 95% CI 0.36-0.97, P = 0.04), respectively, and differences remained significant after adjustments for baseline variables (adjusted OR 0.48, 95% CI 0.26-0.90, P = 0.02). Women >75 years had a lower cardiovascular mortality (6% versus 12%, adjusted OR 0.31, 95% CI 0.12 0.81, P = 0.02). In patients <=75 years, 1-year MACCE rates did not differ between gender (10% and 8% for women and men, adjusted OR 1.28, 95% CI 0.77-2.14, P = 0.34). Rates of TIMI major bleeding for women and men were 4% and 4% in patients >75 years (P = 0.96), and 5% and 3% in those <=75 years (P = 0.11). CONCLUSIONS: The low rates of MACCE observed in elderly women in this patient cohort suggest that with current interventional strategies the gender gap in ACS management has been attenuated. PMID- 30291679 TI - Acceleration of Enzymatic Degradation of Poly(ethylene terephthalate) by Surface Coating with Anionic Surfactants. AB - Enzymatic degradation of poly(ethylene terephthalate) (PET) is promising because this process is safer than conventional industrial approaches. Recently, a cationic PET hydrolase (PETase) was identified from Ideonella sakaiensis. Pre incubation of a low-crystallinity PET film with anionic surfactants prior to initiating the reaction was found to improve PETase activity 120-fold. After 36 h at 30 degrees C, the film thickness decreased by 22 %. The binding of surfactants to the film makes the surface anionic, thereby attracting the cationic PETase. Mutagenesis of PETase showed that the surface cationic region formed by R53, R90, and K95, which are located on the same side as the substrate binding pocket, was crucial for efficient acceleration of activity by the anionic surfactant. Thus, surfactant bound on PET aligns the orientation of the active site to the surface, resulting in efficient hydrolysis. We believe that this approach using PETase could be further improved by designing surfactant molecules for the more efficient enzymatic PET degradation. PMID- 30291680 TI - A Systematic Evaluation of Effect of Adherence Patterns on the Sample Size and Power of a Clinical Study. AB - The objective of our study was to evaluate the effect of adherence patterns on the sample size and power of a clinical trial. Simulations from a population pharmacokinetic/pharmacodynamic (PK/PD) model linked to an adherence model were used. Four types of drug characteristics, such as long (~35 hours) and short (~12 hours) half-life in combination with earlier or delayed time to reach steady state PD end points were studied. Adherence patterns were simulated using Markov chains. Our results clearly demonstrate the significant impact of varying levels and patterns of nonadherence on the sample size and power of a study. For drugs with short half-lives the evidence to support efficacy could be diluted by various patterns of nonadherence that would make its efficacy indistinguishable from the response to placebo. Prospectively utilizing clinical trial simulations with thorough incorporation of various adherence patterns would provide valuable information when designing a trial. PMID- 30291681 TI - Vertebral Comparative Anatomy and Morphological Differences in Anguine Lizards With a Special Reference to Pseudopus apodus. AB - The article reports on the first detailed vertebral and rib morphology of anguine taxon Pseudopus apodus using micro-computed tomography. A comparison shows significant morphological differences of vertebrae of Pseudopus relative to those of Anguis and Ophisaurus. Usually, there are 55 presacral vertebrae, two sacral, and 95-97 caudal vertebrae. Pseudopus apodus can be defined by 23 diagnostic features concerning the vertebral column. Although zygapophyseal articulation between atlas and axis is well developed in limbed anguid gerrhonotine lizards like Abronia or Barisia, it is absent in the extant representatives of the clade Anguinae, which are limbless. Thus, our study brings further support to the hypothesis about the complete reduction of this articulation in forms with reduced or absent limbs. Comparison of adult and juvenile morphology of vertebrae of P. apodus was also analyzed. Heterochrony in the evolution of this taxon was previously confirmed by its skull morphology and it can be also documented on the basis of vertebrae. Our data suggest that a peramorphic heterochronic process played a role in the evolution of this largest extant anguine species. Geometric morphometric analyses revealed a pattern of high vertebral disparity among species. We found a clear separation of limbless forms in morphospace. Pseudopus apodus always clusters within Ophisaurus-species confirming molecular and some morphological phylogenies. Only the first tail vertebra shows a distinct difference to those of other anguids, which might be related to altered locomotion associated to the larger body size in this species. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30291682 TI - Clinical evaluation of the lightening effect of cytidine on hyperpigmented skin. AB - BACKGROUND: Melanocytes, which reside in the basal layer of the epidermis, produce the pigment melanin in cytoplasmic organelles known as melanosomes. Melanosomes are transferred to keratinocytes which provide the color in our skin. Recently, Diwakar et al reported the crucial roles of protein glycosylation in both melanogenesis and melanosome transfer to keratinocytes, and each was inhibited by the nucleotide cytidine. OBJECTIVE: The main objective of this study was to determine the clinical effects of topical application of cytidine to the hyperpigmented regions of the face in a group of human volunteers. METHODS: A randomized, vehicle-controlled study was conducted for 12 weeks on healthy Korean female subjects. Cytidine was formulated into the lotion at concentrations of 2%, 3%, and 4% (w/w) and compared to the vehicle control formulation. The clinical outcomes were evaluated by performing visual assessment grading, measuring melanin index, skin brightness, and skin color parameters. In vitro skin penetration studies were conducted using Franz cell chambers for the 2% cytidine test formulation. RESULTS: The test group showed significant improvements in the visual assessment scores, melanin index, skin brightness, and skin color compared to the control group. Although significant dose-dependent improvements were seen in the clinical study, the in vitro Franz cell studies indicated that the clinical efficacy and potency of cytidine might be further enhanced by formulating a better topical delivery system, which will be the goal of our future studies. CONCLUSIONS: This randomized, double-blind, 12-week clinical study successfully demonstrated the efficacy of cytidine on skin depigmentation in a dose-dependent manner. PMID- 30291683 TI - The health consequences of falsified medicines- A study of the published literature. AB - OBJECTIVES: To analyse and present the literature describing the health consequences of falsified medicines, focusing on mortality and morbidity, as well as the scale of the issue, the geographic extent, the medicines affected, and the harm caused at both the individual and population levels. METHODS: We searched for articles in PubMed, using pre-optimized keywords '(counterfeit OR fake OR bogus OR falsified OR spurious) AND (medicine OR drug)'. Searches up to February 2017 yielded 2006 hits, of which 1791 were full-length articles in English. Among them, we found 81 papers that qualitatively or quantitatively described 48 incidents in which falsified medicines caused patients to suffer serious adverse effects, injury, symptoms or death. RESULTS: The distribution of incidents was examined according to the economic status of the countries involved, regional location in the world, therapeutic category of the medicines, number of incidents and victims by year, and characteristics of the falsified medicines. Among the 48 reported incidents, 27 (56.3%) occurred in developing countries and 21 (43.7%) in developed countries. These incidents involved a total of approximately 7200 casualties including 3604 deaths. CONCLUSIONS: Despite the poor quality of much of the reported data, the results of this study indicate that all types of medications have been targeted for falsification, and falsified medicines have had a serious impact on the health of both adults and children worldwide, with similar numbers of incidents in developing and developed countries. PMID- 30291684 TI - Possible Mechanisms for The Effects of Calcium Deficiency on Male Infertility. AB - Calcium (Ca) is a significant element that acts as an intracellular second messenger. It is necessary for many physiological processes in spermatozoa including spermatogenesis, sperm motility, capacitation, acrosome reaction and fertilization. Although influences of Ca deficiency on sperm function and male infertility have been widely studied, mechanisms for these abnormalities are not well considered. Poor sperm motility, impairment of chemotaxis, capacitation, acrosome reaction and steroidogenesis are the major mechanisms by which Ca deficiency induces male infertility. Therefore, an optimal seminal Ca concentration is required to strengthen sperm function and all steps leading to successful fertilization. Furthermore, identification of these mechanisms provides valuable information regarding the mechanisms of Ca deficiency on male reproductive system and the way for developing a better clinical approach. In this review, we aim to discuss the proposed cellular and molecular mechanisms of Ca deficiency on male reproductive system, sperm function and male fertility. Also we will discuss the valuable information currently available for the roles of Ca in male reproduction. PMID- 30291685 TI - An Overview of The Globozoospermia as A Multigenic Identified Syndrome. AB - Acrosome plays an integral role during fertilization and its absence in individuals with globozoospermia leads to failure of in vitro fertilization (IVF) and oocyte activation post-intracytoplasmic sperm injection (ICSI). A variety of processes, organelles and structures are involved in acrosome biogenesis including, trans-golgi network (TGN), acroplaxome and cellular trafficking. This review aims to explain roles of related signals and molecules involved in this process and also describe how their absence in form of mutation, deletion and knockout model may lead to phenomenon referred to globozoospermia. PMID- 30291686 TI - Prevalence of Sexual Dysfunction among Infertile Women in Iran: A Systematic Review and Meta-analysis. AB - Infertile women are at a higher risk of sexual dysfunction compared to fertile women. Infertility is a major source of stress, anxiety, and depression, which strongly affects sexual health. The aim of this study is to estimate the prevalence of female sexual dysfunction (FSD) among infertile Iranian women. We searched the main international databases (Web of Science, PubMed, Medline, and Scopus) and national databases (Scientific Information Database, Magiran, and IranMedex) from their inception until April, 2017. Due to heterogeneity between the studies, the extracted data were pooled using a random-effects model by Stata software. Out of 313 retrieved studies, we included 18 studies of 3419 infertile women in the meta-analysis. The pooled prevalence of FSD was 64.3% [95% confidence interval (CI): 53.3-75.3]. Our findings revealed that sexual desire (59.9%, 95% CI: 38.7-81.2) was the most prevalent disorder and vaginismus (19.2%, 95% CI: 11.3-27.2) was the least prevalent among infertile women. The results of our metaanalysis suggested that more than 64% of infertile Iranian women reported sexual dysfunction, which was meaningfully high. This study also showed that sexual desire was significantly more common than other sexual dysfunction dimensions and the prevalence of vaginismus was the least common. PMID- 30291687 TI - Association of Tumor Necrosis Factor-alpha (TNF-alpha) -308G>A and -238G>A Polymorphisms with Recurrent Pregnancy Loss Risk: A Meta-Analysis. AB - Background: Multiple studies have been carried out examining the association of tumor necrosis factor-alpha gene (TNF-alpha) promoter region polymorphisms with recurrent pregnancy loss (RPL) risk. However, the results remain controversial and incomplete. Hence, we performed a meta-analysis to evaluate the association of the TNF-alpha -308G>A and -238G>A polymorphisms with RPL risk. Materials and Methods: In this meta-analysis, a comprehensive search of PubMed, Web of Knowledge and EMBASE was performed to identify relevant studies published until December 1, 2017. The associations were assessed by odds ratio (OR) and its corresponding 95% confidence interval (CI). Results: A total of 29 case-control studies, comprising 20 studies on TNF-alpha -308G>A (3,461 cases and 3,895 controls) and nine studies on TNF-alpha -238G>A (2,589 cases and 2,664 controls), were included in the meta-analysis. Overall, we found TNF-alpha -308G>A to be associated with an increase in RPL risk under the homozygote (OR=1.716, 95% CI: 1.210-2.433, P=0.002) and the recessive (OR=1.554, 95% CI: 1.100-2.196, P=0.012) models. TNF-alpha -238G>A was also significantly associated with increased risk of RPL under the allele model (OR=1.554, 95% CI: 1.100-2.196, P=0.012). Stratified analysis revealed a more significant association between theTNF-alpha 308G>A polymorphism and increased RPL risk in Asians under the homozygote (OR=2.190, 95% CI: 1.465-3.274, P<=0.001), the dominant (OR=1.642, 95% CI: 1.269 2.125, P<=0.001) and the recessive (OR=1.456, 95% CI: 1.039-2.040, P=0.029) models, but not in Caucasians. A non-significant association was, however, identified between TNF-alpha -238G>A and RPL risk based on ethnicity. Moreover, TNF-alpha -308G>A and -238G>A polymorphisms were significantly associated with increased risk of RPL in high quality studies and polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) subgroups. Conclusion: The present meta-analysis demonstrates that TNF-alpha -308G>A and -238G>A polymorphisms are associated with an increased risk of RPL. PMID- 30291688 TI - Evaluation of Osteopontin Gene Expression in Endometrium of Diabetic Rat Models Treated with Metformin and Pioglitazone. AB - Background: Osteopontin (Opn) is one of the co-factors involved in cell adhesion and invasion during the implantation process. Several reports have shown Opn expression changes in diabetic condition in several tissues. In addition, an increased incidence of spontaneous abortion is reported in diabetic women. We, therefore, designed a study to evaluate the effects of diabetes on Opn expression at implantation time after treatment with metformin and pioglitazone. Materials and Methods: In this interventional and experimental study, 28 rats were randomly divided into four groups, namely control, diabetic, pioglitazone-treated diabetic rats and metformin-treated diabetic rats. Streptozotocin (STZ) and nicotinamide (NA) were used to induce type 2 diabetes (T2D). During the implantation window, the endometrium was removed and the expression of Opn was analysed by reverse transcription quantitative polymerase chain reaction (RT-qPCR). Results: Opn expression was significantly higher (30.70 fold-changes) in the diabetic group in comparison with the control group (P=0.04). Furthermore, the expression of Opn was significantly lower in the diabetic group treated with pioglitazone when compared with the diabetic group (P=0.04). Conclusion: According to the high Opn expression and the possibility of increased adhesion of endometrial epithelial cells, the invasion of blastocyst may be affected and thus reduced. As pioglitazone significantly reversed the upregulation of Opn in diabetic rats, it may be considered as a therapeutic compound for treating T2D. PMID- 30291689 TI - Detection of Partial AZFc Microdeletions in Azoospermic Infertile Men Is Not Informative of MicroTESE Outcome. AB - Background: Microdeletions of the Yq chromosome are among the most frequent genetic etiological factor of male infertility which spans the azoospermia factor regions (AZFa, AZFb and AZFc). Microdeletions are mostly seen in the AZFc region and usually cover genes actively involved in spermatogenesis. Partial AZFc microdeletions may also occur with various spans, namely gr/gr, b2/b3 and b1/b3. It is known that the outcome of microtesticular sperm extraction (TESE), the surgical process for sperm retrieval from the testis in infertile azoospermic men, may be predicted based on the type of AZF microdeletion. We therefore aimed to evaluate the correlation between partial AZFc microdeletions and microTESE results. Materials and Methods: In this cross-sectional study, 200 infertile azoospermic men referred to the Royan Institute were examined for the presence of partial AZFc microdeletions before undergoing microTESE. Partial AZFc microdeletions were detected by multiplex polymerase chain reaction (PCR) of seven different sequence-tagged site (STS) markers. The data were analyzed with the Chi-square test. Results: Among the 90 patients (45%) with a positive microTESE outcome, 9 (10%) showed a partial microdeletion in AZFc region. Of the 110 (55%) patients with a negative microTESE outcome, 7 (6.3%) had an AZFc partial microdeletion. With respect to the span of the microdeletions, among the 200 patients, 11 (5.5%) were gr/gr and 5 (2.5%) were b2/b3. Statistical analysis showed no significant difference between the patients with and without partial AZFc microdeletions with respect to microTESE outcome. Conclusion: Partial AZFc microdeletions is not a predictor of microTESE outcome in azoospermic men. PMID- 30291690 TI - Varicocelectomy May Improve Results for Sperm Retrieval and Pregnancy Rate in Non Obstructive Azoospermic Men. AB - Background: Assessing the net-results of microsurgical varicocelectomy in infertile men with non-obstructive azoospermic (NOA) and clinical varicocele in five years at Royan Institute. Materials and Methods: This is a descriptive retrospective cohort study. A backward-looking review of patients treated for NOA and varicocele from march 2011 to march 2016 was performed. In addition, MDTESE results of 57 patients with NOA and clinical varicocele, with 537 NOA patients without varicocele were compared. Results: Of 57 patients who underwent varicocelectomy, eight patients (14%) had sperm on sperm analysis post operatively. One of the eight patients was single, and one of them had spontaneous pregnancy (1/7) 14%, and one had a child by microinjection (1/7) 14%. Out of these 8 patients, 6 had hypospermatogenesis pathology. Of 38 patients who underwent MDTESE, 14 patients (36%) had sperm on their testis tissues, but one of them had no egg fertilization. Therefore, the fertilization rate was (92%). Of the remaining 13 patients, 3 had live child birth (3/13) 23%. Sperm retrieval rate (SRR) in NOA men without clinical varicocele was lower from those who had varicocele and NOA (22 vs. 36%). Also live birth rate in NOA men with varicocelectomy was higher than NOA men without varicocele (23 vs. 11%). Conclusion: Microsurgical varicocelectomy in NOA men may have positive effects on post-operative sperm in ejaculate and natural or assisted pregnancies, but it seems that the effect is more significant on MDTESE results and following successful microinjection. Meanwhile, SRR and live birth rate was higher in our patients compare to NOA men without clinical varicocele. PMID- 30291691 TI - Significant Correlation between High-Risk HPV DNA in Semen and Impairment of Sperm Quality in Infertile Men. AB - Background: Human papillomavirus (HPV) is a DNA virus that causes sexually transmitted infections (STI). Recent reports suggest that HPV may affect sperm parameters and lead to male infertility. This study aims to evaluate the correlation between seminal high-risk HPV infection and impairment of sperm quality in infertile Iranian men. Materials and Methods: In this case-control study, we collected fresh semen samples from 70 fertile men and 70 confirmed infertile men who referred to Yazd Infertility Centre in 2015. Semen analyses were performed according to the World Health Organization (WHO) guidelines. High risk HPV DNA was detected by real-time polymerase chain reaction (PCR). Results: A total of 140 subjects participated in the current study. Among 70 confirmed infertile males, only 8 (11.43%) cases tested positive for high-risk HPV and all fertile men were HPV-negative. This data revealed a significant association between high-risk HPV and male infertility (P=0.03). The percentage of normal sperm morphology and sperm motility rate significantly declined in men infected with HPV (P<0.001). Conclusion: There was a significantly higher prevalence of high-risk HPV in infertile men than fertile men. HPV infection seemed to be a risk factor for male infertility. Additional, larger studies should be conducted to confirm the impact of HPV on male infertility. PMID- 30291692 TI - Association between The Number of Retrieved Mature Oocytes and Insulin Resistance or Sensitivity in Infertile Women with Polycystic Ovary Syndrome. AB - Background: The objective of this study was to describe the association between luteinizing hormone (LH)/ follicle-stimulating hormone (FSH) ratio and demographic variables and maturation stage of oocytes in insulinresistant and insulin-sensitive patients with polycystic ovary syndrome (PCOS) in comparison with control group. Materials and Methods: In this case-control study, 60 patients with in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) indication were subdivided into 3 groups as follow: 20 subjects were assigned to control (fertile women with male infertility history) group, 20 subjects with PCOS were insulin resistant (IR) and 20 subjects with PCOS were insulin sensitive (IS). After puncture, retrieved oocytes were classified into metaphase II (MII) as mature and in metaphase I (MI) or germinal vesicle stage (GV) as immature. Regression analyses were used to explore the association between MII oocyte number and demographic and clinical variables. Results: LH/FSH ratio was significantly higher in PCOS-IR women compared to controls but not significantly different from that of PCOS-IS group. PCOS-IR women had lower MII oocyte number compared with that of controls. According to multiple regression analysis, the number of previous assisted reproductive technology (ART) cycles was negatively associated with the number of MII oocytes. Conclusion: Insulin resistance can be associated with reductions in MII oocyte number in patients with PCOS. PMID- 30291693 TI - Dietary Patterns and The Outcomes of Assisted Reproductive Techniques in Women with Primary Infertility: A Prospective Cohort Study. AB - Background: Infertility is one of the most common challenges that women in reproductive age would encounter today. The maternal nutritional status could be a determinant of oocyte quality and embryonic growth. This study was conducted to assess the relationship between dietary patterns and reproductive outcomes in infertile women. Materials and Methods: This prospective cohort study was conducted on 140 women with primary infertility who had referred to Isfahan Fertility and Infertility center, Isfahan, Iran. The average number of total oocytes and metaphase II oocytes, the fertilization rate, the ratio of good and bad quality embryo and biochemical and clinical pregnancy were considered as the outcomes of assisted reproductive techniques (ART). A 168-item food frequency questionnaire was used for estimating the dietary intakes during the last year. Factor analysis was used for identifying the dietary patterns and analysis of variance (ANOVA), analysis of covariance (ANCOVA), chi-square, and logistic regression analysis were used for assessing the relation between dietary patterns and ART's outcomes. Results: Three major dietary patterns (the healthy, western and unhealthy diet) were identified. Women with high adherence to the "healthy diet" had a higher educational level and were employed. There was a significant increase in the average number of total oocytes (P-trend=0.009) and metaphase II oocytes (P-trend=0.006) in the third tertile of "healthy diet" compared to the first tertile. Also, women with high adherence to the second tertile of "unhealthy" diet compared to the first tertile, had a significantly lower chance of getting pregnant [odds ratio (OR): 0.14, 95% confidence interval (CI): 0.3 0.7]. Conclusion: Nutrition status could affect infertility treatment outcomes. Greater adherence to the healthy diet may enhance oocyte quality and quantity. Unhealthy diet could adversely affect the chance of getting pregnant. PMID- 30291694 TI - Satisfaction with Information Provided to Infertile patient Who Undergo Assisted Reproductive Treatment. AB - Background: Potentially modifiable factors, such as the appropriate informing process given to infertile patients, can affect their infertility knowledge and information. This study aims to assess infertility information provided to Iranians who undergo assisted reproductive treatment. Materials and Methods: In this cross-sectional study, participants recruited were a convenience sample of all infertile patients who received assisted reproductive treatments from Royan Institute, Tehran, Iran. Inclusion criteria consisted of: patient's first time visit, no previous infertility treatment failures, and referral to the centre between January and March 2015. A 20-item tool designed by researchers measured patient satisfaction with the infertility informing process. This tool included cause of infertility, type of recommended treatment, diagnostic procedures, approximate treatment duration, success rate of the treatment, approximate cost of treatment, and non-therapeutic factors in treatment success. Results: A total of 235 infertile patients were invited to participate in the study, from which 200 (100 men and 100 women) participants completely responded to the questionnaire with a response rate of approximately 85%. The mean age of participants was 30.93 +/- 5.56 years. In terms of satisfaction with information provided about the cause of infertility, male responders reported the lowest mean score of 3.59 +/- 1.05 compared to female responders (3.82 +/- 0.85, P=0.078). Infertile women had a greater mean score of 3.85 +/- 0.78 than infertile men (3.58 +/- 1.29) in satisfaction with information provided about the type of recommended treatment (P=0.037). There was a statistically significant difference between males (3.26 +/- 1.04) and females (3.58 +/- 0.93) in satisfaction with approximate treatment duration (P=0.031). Conclusion: According to the results, most infertile patients were satisfied with the informing process related to the cause of infertility and recommended therapies. Information about infertility should be provided more systematically to all treated patients by medical staff, especially in terms of success rate of treatment and financial cost of therapy. PMID- 30291695 TI - Correlation of Maternal Stress Because of Positive Aneuploidy Screening Serum Analytes and Uterine Arteries' Doppler Ultrasound Index: A Prospective Cohort Study. AB - Background: Antenatal anxiety or maternal stress is a prevalent chronic mental disorder in pregnant women. We have assessed the effect of maternal stress from positive aneuploidy screening results on the changes in uterine artery blood flow. Materials and Methods: We performed a prospective cohort (one sample) pilot study at a hospital in Tehran, Iran. A total of 60 pregnant women who were candidates for amniocentesis due to abnormal sequential screening test results entered the study. We conducted 2 standard psychological tests, the Spielberger's State-Trait Anxiety Inventory and the Beck Anxiety Inventory, to determine anxiety levels in the participants before amniocentesis and two weeks after amniocentesis. The uterine artery resistance index was also measured before and two weeks after amniocentesis. The level of maternal stress was compared with the uterine artery resistance index. Results: Patients had a mean State Trait Anxiety Inventory score before amniocentesis of greater than 40, which meant that the mothers experienced high anxiety. There were no correlations between both inventories' anxiety scores and uterine artery blood flow before amniocentesis. However, two weeks after amniocentesis, we observed significant negative correlations between the State Anxiety (P=0.0041) and Trait Anxiety (P=0.010) Inventory scores and the uterine artery resistance indexes. Also, there was an association between the decreased right uterine artery resistance index and State Anxiety scores (P=0.036). There were significant correlations between State and Trait Anxiety scores and second trimester analytes of beta-human chorionic gonadotropin (beta-hCG, P<0.001), alpha-fetoprotein (P<0.001), and unconjugated estriol (P=0.048). Conclusion: Maternal anxiety because of positive aneuploidy screening serum analytes and amniocentesis can affect perinatal outcomes via mood based alterations in blood flow of the uterine arteries and the screening markers beta-hCG,unconjugated estriol, and alpha-fetoprotein. PMID- 30291696 TI - Expression of Ghrelin and Its Receptor mRNA in Bovine Oocyte and Cumulus Cells. AB - Energy balance is regulated by ghrelin which is a neuroendocrine modulator. Ghrelin is expressed in reproductive organs. However, the role of ghrelin during in vitro maturation (IVM) and bovine preimplantational development is limited. The purpose of this study was to measure the expression of ghrelin (GHRL) and its receptor growth hormone secretagogue receptor 1A (GHS-R1A) mRNA, and determine cumulus oocyte complex (COC) viability after IVM with 0, 20, 40 and 60 pM of ghrelin. Also, pronuclear formation was recorded after in vitro fertilization (IVF). GHRL and GHS-R1A mRNA expression in oocyte and cumulus cells (CCs) was assessed using reverse transcription-polymerase chain reaction (PCR). Oocyte and CC viability were analyzed with the fluorescein diacetate fluorochrome-trypan blue technique. Pronuclear formation was determined 18 hours after IVF with Hoechst 33342. The results demonstrated that ghrelin mRNA is present in oocyte and CCs before and after 24 hours IVM with all treatments. Ghrelin receptor, GHS R1A, was only detected in oocytes and CCs after 24 hours IVM with 20, 40 and 60 pM of ghrelin. Oocyte viability was not significantly different (P=0.77) among treatments. However, CC viability was significantly lower (P=0.04) when COCs were matured with ghrelin (77.65, 72.10, 66.32 and 46.86% for 0, 20, 40, and 60 pM of ghrelin, respectively). The chance of two pronuclei forming were higher (P=0.03) when ghrelin was not be added to the IVM medium. We found that ghrelin negatively impacts CC viability and pronuclear formation. PMID- 30291697 TI - COMFFETI, Combined Fresh and Frozen Embryo Transfers per Individual: A New Index of Quality Control for The Performance of emberyologic Labs in The Emerging Era of Segmentation of Cycle and Freeze-All Strategy. AB - The efficacy of in vitro fertilization (IVF) for treating human infertility has only one final efficacy index and that is the achievement of a delivery. However, with the evolution of the freeze-all strategy, a new problem is arising for evaluating the performance of an embryological team. The aim of the study was to present a new representative index, combining fresh and frozen embryo transfer success rates. In this opinion article, apart from the effectiveness of managing fresh gametes and embryos, we wish to evaluate the efficacy of the processes of both freezing and thawing of the produced embryos. The reporting of pregnancy rates of an IVF unit in the past was primarily laying in the fresh embryo transfer (ET) pregnancy rates. Now with the most frequent utilization of freeze all strategy, it does not seem logical to report only on poor prognosis patients as all the good cases are postponed for thawed cycles. Ongoing implementation of the freeze-all strategy has indicated the need to establish a new representative index that may combine the success of both fresh and frozen cycles performed in the same woman; an index that may not be biased by the policy of an IVF center towards or against the freeze-all strategy. This newly proposed index, which is referred to as COMFFETI (Combined Fresh #38; Frozen Embryo Transfers per Individual), describes the optimal way to report final reproductive outcomes in the present opinion article. PMID- 30291699 TI - Humanities in the undergraduate medical and midwifery curriculum: a descriptive Italian comparative study. AB - There is an increasing emphasis on humanized care in obstetric and midwifery practice. The goal of this paper is to investigate if and how medical humanities content was present in the undergraduate medical syllabus and how similar or different this is from the undergraduate midwifery program in Italy. A review of the 2017-18 curriculum for Italian Schools of Medicine and of Midwifery was carried out through institutional websites or mailing requests. The following details were collected for each program: the type of humanities content; the academic credits allocated, whether it was taught as a stand-alone (independent) topic or not, and the year(s) of the program when it was provided. Programs were included for 39 Schools of Medicine and 36 Schools of Midwifery. All midwifery schools included at least one subject with humanities content. Five medical schools (12.9) did not appear to have any subjects in this area. Psychology and ethics/bioethics were the most frequently found topics in both disciplines, but, apart from history of medicine, midwifery was much more likely than medicine to include other humanities topics, and especially pedagogy, anthropology, sociology and communication studies, philosophy and cross-cultural studies were rarely or never included in either discipline. A greater breadth of humanities studies was included in midwifery schools. However, their relative importance appears to be low, given the low level of academic credits and lack of presence as independent subjects. PMID- 30291698 TI - Perspective review of what is needed for molecular-specific fluorescence-guided surgery. AB - Molecular image-guided surgery has the potential for translating the tools of molecular pathology to real-time guidance in surgery. As a whole, there are incredibly positive indicators of growth, including the first United States Food and Drug Administration clearance of an enzyme-biosynthetic-activated probe for surgery guidance, and a growing number of companies producing agents and imaging systems. The strengths and opportunities must be continued but are hampered by important weaknesses and threats within the field. A key issue to solve is the inability of macroscopic imaging tools to resolve microscopic biological disease heterogeneity and the limitations in microscopic systems matching surgery workflow. A related issue is that parsing out true molecular-specific uptake from simple-enhanced permeability and retention is hard and requires extensive pathologic analysis or multiple in vivo tests, comparing fluorescence accumulation with standard histopathology and immunohistochemistry. A related concern in the field is the over-reliance on a finite number of chosen preclinical models, leading to early clinical translation when the probe might not be optimized for high intertumor variation or intratumor heterogeneity. The ultimate potential may require multiple probes, as are used in molecular pathology, and a combination with ultrahigh-resolution imaging and image recognition systems, which capture the data at a finer granularity than is possible by the surgeon. Alternatively, one might choose a more generalized approach by developing the tracer based on generic hallmarks of cancer to create a more "one-size-fits-all" concept, similar to metabolic aberrations as exploited in fluorodeoxyglucose - positron emission tomography (FDG-PET) (i.e., Warburg effect) or tumor acidity. Finally, methods to approach the problem of production cost minimization and regulatory approvals in a manner consistent with the potential revenue of the field will be important. In this area, some solid steps have been demonstrated in the use of fluorescent labeling commercial antibodies and separately in microdosing studies with small molecules. PMID- 30291700 TI - Optimal outcomes and women's positive pregnancy experience: a comparison between the World Health Organization guideline and recommendations in European national antenatal care guidelines. AB - BACKGROUND: The publication of the World Health Organization (WHO) recommendations on antenatal care in 2016 introduced the perspective of women as a necessary component of clinical guidelines in maternity care. WHO highlights the crucial role played by evidence-based recommendations in promoting and supporting normal birth processes and a positive experience of pregnancy. This paper aims to explore and critically appraise recommendations of national antenatal care guidelines across European countries in comparison with the WHO guideline. METHODS: We collected guidelines from country partners of the EU COST Action IS1405. Components of the documents structure and main recommendations within and between them were compared and contrasted with the WHO guideline on antenatal care with a particular interest in exploring whether and how women's experience was included in the recommendations. RESULTS: Eight out of eleven countries had a single national guideline on antenatal care while three countries did not. National guidelines mostly focused on care of healthy women with a straightforward pregnancy. The level of concordance between the national and the WHO recommendations varied along a continuum from almost total concordance to almost total dissonance. Women's views and experiences were accounted for in some guidelines, but mostly not placed at the same level of importance as clinical items. CONCLUSIONS: Findings outline convergences and divergences with the WHO recommendations. They highlight the need for considering women's views more in the development of evidence-based recommendations and in practice for positive impacts on perinatal health at a global level, and on the experiences of each family. PMID- 30291701 TI - Ovarian tumors secreting androgens: an infrequent cause of hyperandrogenism. AB - INTRODUCTION: The sex cord-stromal tumors are relative rare, comprising 5-8% of all ovarian neoplasms. OBJECTIVE: Review of 13 cases of androgen tumors and a description of 3 cases: Leydig tumor, steroid cell (NOS) tumor and Sertoli-Leydig tumor. RESULTS: Twelve patients were menopausal and one patient of reproductive age. In all cases, regardless of the histological variety, women presented symptoms of hyperandrogenism and virilization. All had increased values of total testosterone. In all cases surgical treatment was performed, with favorable clinical and biochemical evolution. CONCLUSIONS: Sex cord stromal tumors of the ovary are rare, and can be characterized by virilization for most patients. The majority of the tumors are benign, with few cases having low-grade malignancy. The suspicion and correct evaluation of these women will lead to an early diagnosis and improve their quality of life. PMID- 30291702 TI - Effectiveness, quality of life and sexual functions in women with anterior compartment prolapse treated by native tissue repair: a mini-review. AB - Anterior compartment defect is the most common pelvic organ prolapse. It is defined as the descent of the bladder into the anterior vaginal wall. The etiology is multifactorial and the main risk factors are vaginal delivery and conditions associated with increased abdominal strain. Aging is significantly associated with the prevalence and severity of pelvic organ prolapse. Treatment may be conservative or surgical according to symptoms, prolapse degree and not forgetting both patient and doctor preferences. The aim of this work is to identify the most efficient surgical treatment of cystocele and its recurrences. There are two different surgical approaches for the treatment of cystocele: traditional repair and mesh repair. Prosthetic treatment gives higher anatomical success rate but traditional anterior repair has less complication demonstrating a lower risk of reoperation. Surgical treatment in general improves both the quality of life and the sexual function. We carried out a research on the impact of the anterior defect before and after native tissue surgery on quality of life and sexual function. The efficacy and complications of the treatment were also assessed. PMID- 30291703 TI - Fulminant Staphylococcal Infections. AB - Fulminant staphylococcal infection indicates an explosive, intense, and severe infection occurring in a patient whose previous condition and antecedent would never have caused any anticipation of life-threatening development. This includes necrotizing pneumonia, necrotizing fasciitis, and to some extent toxic shock syndrome and infective endocarditis. In the three former diseases, toxin production plays a major role whereas in the latter (fulminant presentation of infective endocarditis), association with any particular toxinic profile has never been demonstrated. This article reviews the clinical, pathophysiological, and therapeutic aspects of these diseases. PMID- 30291705 TI - Physician Compensation, Accountability and Performance in Canada: Changing the Pas de Deux. AB - Physician bargaining with provincial governments has been a challenge in the provinces of Canada since the origins of medicare, when this bilateral negotiation first began in Saskatchewan and was eventually codified in the Canada Health Act. In recent years, the emergence of accountability for performance has become a central policy focus in advanced countries to raise the bar on the quality and value of physician services and their effective integration within the broader healthcare system. The challenge has been to create real accountability while balancing growth in physician incomes with fiscal capacity and affordability. This commentary reflects a rich variety of perspectives from our contributing authors. It also lays out a number of challenges and changes that may be required to strengthen the importance of accountability for fair payments within Canadian medicare. PMID- 30291706 TI - Doctors and Canadian Medicare: Improving Accountability and Performance. AB - Physician compensation has been a rapidly growing segment of healthcare costs in Canada since the late 1990s. In comparative terms, Canadian physicians are now well compensated compared to physicians in other high-income countries. This has caused provincial governments to begin constraining physician remuneration. However, physician payment should be examined in a larger governance context, including the potentially changing role of physicians, as provincial governments try to improve quality, increase coordination and improve overall health system performance. Although limited progress has been made through primary care reforms in a few jurisdictions, substantive improvement has been hampered by a misalignment between the policy goals and intentions of provincial governments and existing governance and accountability structures. This creates an environment in which both administrators and physicians feel they have limited input or control, seeding an adversarial rather than a collaborative relationship. Effective reform will require addressing governance and accountability at the same time as physician payment. PMID- 30291707 TI - Physician Service Costs: Is There Blame to Share Around? AB - The rising portion of national income devoted to healthcare in general and the portion allocated to physician services have been a focus of the health policy literature for some time. Greater recognition should be given to the fact that the observed trends in physician service expenditures are the product of the interaction between physicians and provincial governments. Improving the productivity of healthcare systems in the delivery of high-quality primary care will require moving beyond simple oversight to deeper engagement with physicians as partners in system improvement. PMID- 30291704 TI - Mycobacteriophages. AB - Mycobacteriophages are viruses that infect mycobacterial hosts. A large number of mycobacteriophages have been isolated and genomically characterized, providing insights into viral diversity and evolution, as well as fueling development of tools for mycobacterial genetics. Mycobacteriophages have intimate relationships with their hosts and provide insights into the genetics and physiology of the mycobacteria and tools for potential clinical applications such as drug development, diagnosis, vaccines, and potentially therapy. PMID- 30291708 TI - Healthcare Delivery and Physician Accountability in Quebec: A System Ready for Change. AB - In hindsight, there have been unintended systemic consequences stemming from the traditional roles physicians have assumed and the structures within which they have been permitted to organize themselves. It is critical that the national discussion take account of this because we must reconcile ourselves to the current reality in which all other allied healthcare professionals are practising at "the top of their licence." Furthermore, the pace of technological change, especially the deciphering of the genome and the digitalization of virtually everything, has engendered a revolution characterized by the democratization of knowledge and technology, so that the point of care will be wherever the patient is. Dysfunctional reimbursement schemes and a lack of accountability are merely symptoms of a system that must change. PMID- 30291709 TI - Doctors and Canadian Medicare: Improving System Performance Requires System Change. AB - Many of the issues raised and insights provided by Marchildon and Sherar (2018) in their essay on doctors and Canadian medicare are on target. The inadequacy of available data on physician payment, however, calls into question the robustness of some interprovincial comparisons, and when it comes to compensation, comparisons to US physicians would be most relevant. In contrast to their assertion of a steadily increasing growth rate in physician expenditure, a more recent and longer view shows historically low growth in the past few years. Furthermore, the blame assigned to physicians and their medical associations needs to be shared with governments and most of all could be attributed to the lack of system structures and supports for improvement. New governance arrangements at the group or regional levels are needed but are insufficient in themselves. The additional features embodied in the Patient's Medical Home are essential for advancing primary care. Going even further, full population registration, greater availability of alternate payment arrangements, active participation of physicians in healthcare administration and support for meaningful measurement and feedback loops are among the changes required to transform Canadian medicare. PMID- 30291710 TI - Improving Physician Accountability through Primary Care Reform in Alberta. AB - Like other Canadian provinces and territories, Alberta has been attempting to reform primary care since the mid-1990s. Although initially these efforts were focused almost exclusively on the method of payment for physicians, since 2003, the focus of government policy has broadened to include other aspects of practice, including governance and accountability, improved continuity, the use of a team-based approach and the use of electronic information systems. Although significant progress has been made, Alberta continues to face challenges. PMID- 30291711 TI - From Autonomous Gatekeepers to System Stewards: Can the Alberta Agreement Change the Role of Physicians in Canadian Medicare? AB - Marchildon and Sherar's (2018) "Doctors and Canadian Medicare" presents a specific dilemma for healthcare reform: the ability of physicians to negotiate ever-increasing incomes without reference to the consequences to healthcare costs or provincial budgeting. This commentary situates that discussion in the broader debate of the challenges to healthcare reform as exemplified by studies such as Paradigm Freeze (Lazar et al. 2013) and the ability of provincial medical associations to act as both system insiders (gatekeepers) and outsiders (with no responsibility for system finances). The resolution to this dilemma may be to follow the lead of the Alberta government by negotiating a stewardship role for physicians that requires them to take broader governmental goals into account. There is evidence to suggest that physicians may be the best actors to insist on and enforce changes in physician behaviour. Furthermore, adding physicians as stewards of the system may help create better checks and balances in the currently dysfunctional dynamics between federal and provincial stewards. PMID- 30291712 TI - Canada's Ailing Healthcare System: It's the Doctors' Fault? AB - The Marchildon and Sherar (2018) paper provides some useful insights: the role of primary care, improved approaches to physician compensation and the importance of accountability and governance. But their approach of focusing on doctors, including their compensation, misses the boat. Canada's healthcare system needs a major overhaul to improve integration and reward good performance for patient care going beyond medical practitioner compensation.

AB - This commentary responds to Marchildon and Sherar's (2018) paper, "Doctors and Canadian Medicare: Improving Accountability and Performance," in which they explore questions around governance and physician accountability in Canada. This response situates the issues raised in a northern context by sharing experiences with primary care reform in the Northwest Territories and exploring the implications these changes have had for physician accountability and reported system improvements. Physician leadership and accountability are further explored in the northern context, where health systems for Indigenous communities include multiple jurisdictions and transitions in governance advance the self-government, land claims and treaty rights of Indigenous peoples. PMID- 30291714 TI - Measuring Physicians' Incomes with a Focus on Canadian-Controlled Private Corporations. AB - Understanding physician remuneration and its growth is extremely complex, much more so than for a typical worker. Highlighting one narrow aspect of this issue, this paper focuses on governments' increased incentives for physicians to incorporate and the ensuing physician response in the period 1996-2011. Nationally, incorporation rates increased for both general practitioners and specialists between 1996 and 2011. We observe that the largest changes in provincial regulation were in Ontario, and incorporation increased from 18% in 2001 to 54% five years later. Incorporation is less common in Quebec, where the incentives were the weakest. Married male physicians, middle-aged physicians (regardless of sex), physicians with higher incomes and physicians born outside of Canada are all more likely to incorporate their practices. On average, incorporated physicians realized a 4% reduction in personal income taxes and accumulated retained earnings of at least $10,000 per annum in their Canadian controlled private corporations in our data period. The benefits of incorporation stem largely from retained earnings and income splitting. Many physicians benefit from one or both; however, the benefits of incorporation are not equally distributed. Sex, marital status and income affect the magnitude of the financial benefit of incorporation. PMID- 30291715 TI - Value for Money through Effective Stewardship. AB - The respondents all raised valuable, informative points in response to our Invited Essay. There was convergence around the need to alter governance structures at the same time as payment arrangements for physicians to achieve higher-performing health systems within Canada. At the same time, there were different views on how best to address the disconnect between levels of physician remuneration and accountability for healthcare performance and delivery. In addition to ongoing efforts to improve governance, such as the recent amendments to the government-physician agreement in Alberta, individual provincial governments can and should take the lead in initiating and evaluating further payment and governance experiments.

AB - PURPOSE: Neuroendocrine tumors (NETs) are now routinely treated by radiopeptide targeted therapy using somatostatin receptor-binding peptides such as 90 Y- and 177 Lu-DOTATOC. The objective of this work was to develop a biokinetics model of 90 Y labelled DOTATOC, which is applied in the therapy of NETs to estimate doses in kidney and tumor. METHODS: A multi-compartment model described by two sets of differential equations, one set for the actual 30-min infusion and the other set for the post-infusion period was developed and activities were measured by liquid scintillation counting in blood (compartment 1) and the urine (compartment 3). The inter-compartment transfer coefficients, lambdaij , were varied to yield the best fit of the calculated to the measured time-activity data and the 90 Y DOTATOC time-activity data in the five-compartments comprising the human body were thus determined. The resulting time-activity curves were integrated over the interval from 0 to 72 h post administration to obtain the number of radioactive decays in each compartment and, in case of the kidneys and tumor, then multiplied by the self-dose 90 Y beta particle absorbed fraction, determined by Monte Carlo (MC) simulation, the kidney and tumor absorbed doses. RESULTS: Transfer coefficients lambdaij , were determined for five-compartments for all patients. Time- activity curves of 90 Y-DOTATOC in 14 patients were determined, and two typical ones are shown graphically. Absorbed doses in the tumor and kidneys, obtained by the developed method, were determined. The mean absorbed dose in a kidney per unit of administered activity is 1.43 mGy/MBq (range 0.73-2.42 mGy/MBq). The tumor dose was determined as 30.94 mGy/MBq (range 20.05-42.31 mGy/MBq). CONCLUSION: Analytical solution of a biokinetic model for 90 Y-DOTATOC therapy enabled determination of the transfer coefficients and derivation of time activity curves and kidney and tumor absorbed doses for 14 treated patients. The model can be applied to other radionuclides where elimination is predominantly through urine, which is often the case in radiopharmaceuticals. PMID- 30291716 TI - Peptic Ulcer Is the Most Common Cause of Non-Variceal Upper-Gastrointestinal Bleeding (NVUGIB) in China. AB - BACKGROUND This study aimed to discover the common cause of non-variceal upper gastrointestinal bleeding (NVUGIB) by conducting a multi-center retrospective study from 2008 to 2012. MATERIAL AND METHODS Hospitalized patients ages >=18 years old, from 8 hospitals in China, diagnosed with NVUGIB by endoscopy from 1 January 2008 to 31 December 2012 were enrolled. Questionnaires were developed and a data-entry graphical user interface was designed by using EpiData software. RESULTS Total of 2977 hospitalized patients from 8 medical centers were included. A total of 95.47% (2842/2977) of patients were admitted to a general ward, 3.53% (105/2977) were admitted to an emergency ward, and 1.00% (31/2977) were admitted to an intensive care unit. Peptic ulcer remained the most common cause of NVUGIB (73.26%), but there was a declining trend in its constituent ratio, from 2008 to 2012. A total of 14.41% (429/2977) of patients had co-morbid conditions, 92.85% (2764/2977) used proton-pump inhibitors (PPIs) prior to endoscopic treatment, 19.65% (585/2977) underwent emergency endoscopy, and 23.45% (698/2977) received a transfusion of red blood cell suspensions. A total of 5.34% (159/2977) underwent endoscopic therapy, with a treatment rate of 16.9% in high-risk peptic ulcer patients (96/568). A total of 7.69% (237/2977) were administered aspirin, of whom 32.50% (77/237) resumed aspirin intake after gastrointestinal bleeding was controlled. The median length of hospitalization was 8 days (IQR, 5-11) and the mortality rate was 1.71% (51/2977). CONCLUSIONS Peptic ulcer was still the most common cause of NVUGIB in China. The proportion of patients with high-risk peptic ulcer bleeding who received endoscopic therapy was 16.9%. Only 19.65% of NVUGIB patients underwent emergency endoscopy. PMID- 30291718 TI - Infimal convolution-based regularization for SPECT reconstruction. AB - PURPOSE: Total variation (TV) regularization is efficient in suppressing noise, but is known to suffer from staircase artifacts. The goal of this work was to develop a regularization method using the infimal convolution of the first- and the second-order derivatives to reduce or even prevent staircase artifacts in the reconstructed images, and to investigate if the advantage in noise suppression by this TV-type regularization can be translated into dose reduction. METHODS: In the present work, we introduce the infimal convolution of the first- and the second-order total variation (ICTV) as the regularization term in penalized maximum likelihood reconstruction. The preconditioned alternating projection algorithm (PAPA), previously developed by the authors of this article, was employed to produce the reconstruction. Using Monte Carlo-simulated data, we evaluate noise properties and lesion detectability in the reconstructed images and compare the results with conventional total variation (TV) and clinical EM based methods with Gaussian post filter (GPF-EM). We also evaluate the quality of ICTV regularized images obtained for lower photon number data, compared with clinically used photon number, to verify the feasibility of radiation-dose reduction to patients by use of the ICTV reconstruction method. RESULTS: By comparison with GPF-EM reconstructed images, we have found that the ICTV-PAPA method can achieve a lower background variability level while maintaining the same level of contrast. Images reconstructed by the ICTV-PAPA method with 80,000 counts per view exhibit even higher channelized Hotelling observer (CHO) signal to-noise ratio (SNR), as compared to images reconstructed by the GPF-EM method with 120,000 counts per view. CONCLUSIONS: In contrast to the TV-PAPA method, the ICTV-PAPA reconstruction method avoids substantial staircase artifacts, while producing reconstructed images with higher CHO SNR and comparable local spatial resolution. Simulation studies indicate that a 33% dose reduction is feasible by switching to the ICTV-PAPA method, compared with the GPF-EM clinical standard. PMID- 30291719 TI - Instruments evaluating the clinical findings of laryngopharyngeal reflux: A systematic review. AB - OBJECTIVES: To identify the instruments for evaluating the clinical findings (ICFs) of laryngopharyngeal reflux (LPR) designed for use with regard to diagnosis and treatment effectiveness. METHODS: The PubMed, Scopus, and Cochrane databases were used to search for subject headings following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. Three investigators retrieved relevant studies published between 1990 and 2018 describing the evolution of laryngopharyngeal findings throughout LPR treatment. Issues of clinical relevance, that is, LPR diagnosis, treatments, and signs assessed for diagnosis or as therapeutic outcomes, were assessed. The investigators also evaluated the psychometric properties (conceptual model, content validity, consistency, reliability, concordance, convergent validity, known-groups validity, responsiveness to change, and interpretability) of the ICF. The risk of bias was assessed with the tool of the Clarity Group and Evidence Partners. RESULTS: The search identified 1,227 publications with a total of 4,735 LPR patients; of these studies, 53 met the inclusion criteria. Of these 53 studies, we identified 10 unvalidated and six validated ICFs. None of the validated ICFs included all the psychometric properties. The main identified deficiencies related to ICF psychometric validation included variable construct validity, disparate and uncertain reliabilities, and a lack of interpretability. The lack of consideration of certain LPR laryngeal and extralaryngeal signs is the main weakness of ICFs, biasing content, and construct validities. CONCLUSION: The low specificity of LPR signs, the lack of consideration of many findings, and the absence of a gold standard for diagnosis constitute barriers to the further validation of these ICFs. Additional studies are needed to develop complete and reliable ICFs. Laryngoscope, 2018. PMID- 30291720 TI - Convergence between Rorschach and self-report: A new look at some old questions. AB - OBJECTIVE: This study presents an examination of the influence of response format on convergence between performance-based and self-report assessments of similar mental health constructs, to determine if such method variance might account for prior findings of lack of relationship. METHODS: An online sample of 455 participants (57% male; average age, 35.5) completed a multiple-choice version of the Rorschach and two self-report instruments, the Personality Assessment Inventory (PAI) and the International Personality Item Pool (IPIP) representation of the domain traits of the five-factor model (FFM). RESULTS: Several significant interrelationships emerged between the Rorschach Amplified Multiple Choice Test and the PAI and IPIP five-factor scales. CONCLUSIONS: These findings suggest that the Rorschach can correlate meaningfully with similar constructs assessed using self-report methodology when comparable response formats are utilized.

AB - OBJECTIVE: Due to the limited effectiveness of extant prevention and intervention strategies, the current study is an initial evaluation of a cognitive behavioral group intervention, originally designed to treat symptoms of depression and anxiety, for youth who experienced peer victimization. METHODS: Twelve third- through fifth-grade youth participated in the intervention, and their data were compared with 12 youth who were a part of a naturalistic control group. Additionally, school-wide data are reported to provide overall school trends. RESULTS: Whereas the intervention group participants exhibited decreases in relational victimization, depressive symptoms, and passive coping, the control group participants exhibited nonsignificant increases in relational victimization, depressive symptoms, and passive coping. School-wide data also indicated overall increases in relational victimization and depressive symptoms, but no changes in passive coping. CONCLUSION: Findings suggest that cognitive behavioral group interventions may provide a promising avenue for addressing the mental health needs of victimized elementary school-age youth. PMID- 30291722 TI - Vps74p controls Golgi size in an Arf1-dependent manner. AB - The oncogene GOLPH3 is implicated in Golgi size regulation, a function yet to be experimentally linked to its PI4P effector function or the Golgi cisternal maturation in general. Moreover, its yeast homolog, Vps74p is not yet implicated in Golgi size regulation. Our results indicate that VPS74 deletion increases the late Golgi cisternal size and the cisternal maturation frequencies, and destabilizes the Golgi PI4P gradient in budding yeast. Overexpression of Arf1 can suppress this cisternal enlargement and increased maturation frequency phenotype of ?vps74. ?arf1 alters Vps74p and PI4P distribution along the Golgi stacks. We conclude that Vps74p, the downstream effector of Arf1, regulates Golgi size by altering its cisternal maturation frequency and by maintaining the PI4P distribution along the Golgi compartments. PMID- 30291723 TI - MicroRNA miR-181a/b-1 controls MAIT cell development. AB - Mucosal-associated invariant T (MAIT) cells constitute a major fraction of innate like T cells in humans with critical roles in defense against microbial pathogens and in maintaining mucosal integrity. However, the molecular mechanisms underlying MAIT cell development remain largely elusive. Here we investigated the role of miR-181a/b-1, a pair of microRNAs that serve as rheostat of TCR signal strength, in this process. Loss of miR-181a/b-1 in mice resulted in a profound arrest in early MAIT cell development. As a consequence, in the absence of miR 181a/b-1, thymic MAIT cells failed to acquire functional maturity based on expression of transcription factors PLZF, T-bet and RORgammat. Temporal analysis of development using a molecular timer in combination with loss of miR-181a/b-1 revealed that MAIT cells complete functional maturation in the periphery and indicates that functionally mature MAIT cells in the thymus are long-term resident cells. Thus, our study provides insight into the dynamics of MAIT cell development in vivo. Of note, deletion of miR-181a/b-1 alone completely mirrored loss of all miRNAs. PMID- 30291724 TI - Sensitivity of the IQM transmission detector to errors of VMAT plans. AB - PURPOSE: The integral quality monitor (IQM) transmission detector is a wedge shaped large area ionization chamber that reports a position-weighted dose area product for each control point of an IMRT or VMAT plan. In this study, the accuracy of the signal prediction is verified for the Synergy Agility MLC. Tolerance criteria for VMAT plan verification with the IQM were obtained from the observed sensitivity for the detection of incorrectly delivered plans. METHODS: The predicted IQM signal was compared to the measured signal recorded for a set of 30 VMAT plans for each beam quality of 6 and 10 MV. The system's capability to detect incorrectly delivered plans was tested by measuring altered plans containing small, random deviations. In addition, the observed deviations were related to measurements performed with a second QA phantom. RESULTS: The cumulative IQM signal per arc deviated from the respective calculation on average by -0.48% (6 MV) and +0.21% (10 MV) with a standard deviation of 1.08% in both cases, suggesting a 2% warning and 3% action threshold as plan acceptance criteria. This choice was confirmed by the optimum threshold of 2.5% obtained via receiver operating characteristic (ROC) analysis. Reproducibility of individual control points in multiply measured plans was low (on average 7% for 1SD) and thus, segment-by-segment comparison was impractical. A suitable criterion to resolve the angular distribution of the plan was identified by binning three to five control points as a running average. While the correlation between IQM signal deviations and gamma passing rates obtained with the ArcCHECK phantom was low for clinical plans, it was apparent for erroneous plans. Binning led to even higher sensitivity to errors. CONCLUSIONS: The IQM was able to detect induced errors at least as reliable as the standard phantom and showed the potential to be used in pretreatment plan verification to ensure the correct plan transfer and delivery. However, there is no direct correlation between the IQM signal deviation and DVH metrics, so the IQM should be primarily used to screen for errors. Finer diagnostics should then be carried out using a different phantom. PMID- 30291725 TI - Legends of allergy: Carla Bruijnzeel-Koomen. PMID- 30291726 TI - Caring for "Super-utilizers": Neoliberal Social Assistance in the Safety-net. AB - Hospitals throughout the United States are implementing new forms of care delivery meant to address social needs for structurally vulnerable patients as a strategy to prevent emergency department visits and hospitalizations and to thereby reduce costs. This article examines how the deployment of social assistance within a neoliberal institutional logic involves the negotiation and alignment of economistic values with ethics of care. We focus on care practices meant to stabilize the socioeconomic conditions of the most expensive patients in the health care system-the "super-utilizers"-through the provisioning of basic resources such as housing, food, transportation, and social support. These patients typically suffer from multiple chronic illnesses accompanied by conditions of poverty, housing and food insecurity, exposure to violence and trauma, and associated substance use and mental health problems. We offer an account of how practices of social assistance are being forged within contexts defined by neoliberal governance. PMID- 30291727 TI - Genetic characterization and diversity of porcine circovirus type 2 in non vaccinated South African swine herds. AB - The porcine circovirus type 2 (PCV2) is a swine infectious viral pathogen of great significance in global swine herds. It was recently detected at another Province of South Africa sequel to the first detection of North American-like strain (PCV2a) at Gauteng about two decades ago, but there is a dearth of information about the genomic features and diversity of the viral strains in circulation within the country and the entire sub-Saharan Africa region. To date, only one complete genome of the virus from South Africa is available on global data base. This current effort is therefore geared towards the full-genome characterization of the circulating PCV2 strains in the pigs of Eastern Cape Province. With the use of conventional polymerase chain reaction method, fifteen complete PCV2 genomes were successfully amplified, sequenced and assembled from field samples obtained from non-vaccinated pigs in the region. Neighbor Joining and Maximum Likelihood phylogenetic analyses of the ORF2 gene and full genomes unanimously showed that most of the assembled genomes (11) belong to genotype PCV2b. Furthermore, three of the characterized sequences formed clade with other reference mutant PCV2b and PCV2b subtype 1C (i.e. PCV2d) strains from the USA, China and South Korea. The last sequence, however, clustered with other reference strains belonging to PCV2 intermediate clade 2 (PCV2-IM2), recently identified in a global PCV2 strains phylogenetic analysis. This study reports the first complete genome sequences of PCV2b, PCV2d and PCV2-IM2 in pigs from South Africa, and it gives a possible insight into the genetic characteristics and variability of the viral strains presently in circulation within the country. It further emphasizes the need for more stringent measures in curtailing the introduction and spread of transboundary swine pathogens in the country and entire Southern African region. PMID- 30291728 TI - Predicting outcomes and complications following radioiodine therapy in Graves' thyrotoxicosis. AB - OBJECTIVE: Radioiodine (RAI) is an effective treatment for Graves' thyrotoxicosis but is associated with a failure rate of 15% and may be a risk factor for thyroid eye disease (TED) and weight gain. We sought to examine predictors of RAI failure, weight gain, TED and patient satisfaction. DESIGN: Retrospective cohort study. PATIENTS: A total of 655 episodes of RAI in Graves' thyrotoxicosis patients (2006-2015). MEASUREMENTS: Biochemical assessment, including TFTs and thyrotropin receptor antibodies (TRAb), clinical features (eg, TED, weight and thionamide use) and patient questionnaire. RESULTS: The treatment failure rate was 17%. Failure was greater with higher fT4 (P = 0.002) and higher TRAb (P = 0.004). Failure rate was 42.2% when TRAb >40 U/L. Median weight gain was 3.2 kg in those with normal fT4 prior to RAI and 5.8 kg when fT4 was elevated (P < 0.001). New TED developed in 7.6% but was not associated with post-RAI dysthyroidism. Treatment satisfaction was generally high (median response 8/10). CONCLUSIONS: Treatment failure after RAI occurs in predictable groups and this should be reflected in the information provided to patients. Weight gain is common and may not entirely be explained by a return to pre-thyrotoxic baseline. We were unable to detect any significant impact of post-RAI dysthyroidism on weight gain, TED or thyroid symptoms in this large cohort.

Reduction of cariogenic bacteria and promotion of remineralization are effective ways to control them. This study was to develop bifunctional anticaries peptides with antibacterial and remineralizing properties. METHODS: We designed peptides TDH19, TNH19, and TVH19 and selected one through comparing their minimal inhibitory concentrations (MICs) and minimal bactericidal concentrations (MBCs) against Streptococcus mutans and their reaction on mineralization. Then the bifunction of the selected peptide was studied through: (a) effects on S. mutans biofilm, (b) remineralizing effects on initial lesions and (c) stability in saliva and cytocompatibility to human oral keratinocytes (HOKs). RESULTS: TVH19 showed the lowest MIC and MBC and a better mineralizing ability. It inhibited new biofilm formation and reduced the viability of old biofilm (p < 0.05). Treating initial caries with TVH19 led to greater recovery of surface microhardness, shallower lesion depth, and higher mineral content (p < 0.05). No significant differences were observed between TVH19 and NaF samples (p > 0.05). TVH19 was stable in saliva and had little effect on HOKs. CONCLUSIONS: The novel bifunctional anticaries peptide TVH19 was developed with remarkable antibacterial activity and the potential to enhance remineralization of initial caries. PMID- 30291731 TI - Autophagy inhibition-enhanced assembly of the NLRP3 inflammasome is associated with cisplatin-induced acute injury to the liver and kidneys in rats. AB - The nucleotide-binding oligomerization domain-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome has a key role in the inflammatory response. We found that cisplatin (7.5, 15 mg/kg, IV) could induce acute injury to the liver and kidneys of rats. Western blot and immunohistochemical analyses showed that expression of NLRP3, caspase-1 and interleukin-1beta was upregulated significantly in a dose-dependent manner after cisplatin exposure. Autophagy could inhibit NLRP3 expression and assembly of the NLRP3 inflammasome. Expression of light chain 3 II/I and p62 suggested that autophagy was inhibited during injury to the liver and kidneys. These data suggested that cisplatin might activate NLRP3 by inhibiting autophagy in the liver and kidneys of rats. PMID- 30291732 TI - Isolation and genetic characterization of H13N8 low pathogenic avian influenza virus from migratory birds in eastern China. AB - Low pathogenic avian influenza virus (LPAIV) is an important zoonotic pathogen. Migratory birds are the natural reservoir for all 16 haemagglutinin (HA) and nine neuraminidase (NA) subtypes of LPAIV. Surveillance of LPAIV in migratory waterfowl and poultry is important for animal and public health. An understanding of the ecology and epidemiology of LPAI viruses in their reservoirs is beneficial for routine surveillance projects. Here, we report the isolation of an H13N8 LPAIV from black-tailed gulls in eastern China. Full genome sequences of this isolate were determined. Genetic analysis of the HA and NA segments of this isolate showed that this H13N8 LPAIV was derived from the Eurasian lineage. Additionally, we speculate that this H13N8 LPAIV was a reassortant between the North American and Eurasian lineages. Interestingly, we identified amino acid motifs responsible for increased virulence or transmission of influenza viruses in mammals. We also found weak but measurable haemagglutination inhibition antibody titers against H13N8 virus in serum samples collected from chickens. These results suggest that continued surveillance for LPAI viruses in migratory birds and poultry is required.

PMID- 30291735 TI - Nebivolol enhances the effect of alendronate against methylprednisolone-induced osteoporosis in rats. AB - This study aimed to assess the possible modulatory effect of nebivolol against methylprednisolone-induced osteoporosis in rats. Weekly administration of methylprednisolone (7 mg/kg), for six consecutive weeks caused significant increases in serum calcium, bone malondialdehyde, and hydroxyproline as well as serum alkaline phosphatase, but it significantly decreased serum phosphorous and osteocalcin, bone reduced glutathione, and nitric oxide (NO) as well as bone antioxidant enzymes activities compared with the control group. The results were confirmed by histopathological findings of femur bone. On the other hand, administration of alendronate (1 mg/kg) with nebivolol (1.5 mg/kg) orally and daily for seven consecutive days after methylprednisolone treatment caused marked mitigation in the above-mentioned parameters compared with methylprednisolone group. In conclusion, nebivolol proved to enhance the effect of alendronate in modulating methylprednisolone osteoporotic effect, which might be attributed to its release of NO together with its profound reducing capability in the oxidative cascade of bone tissue. PMID- 30291736 TI - Common health problems in safety-net primary care: Modeling the roles of trauma history and mental health. AB - OBJECTIVE: This study described trauma exposure and investigated mediational effects of mental health on the relationships between trauma and pain, sleep, smoking, and general health. METHOD: Participants were 210 low-income primary care patients. The study used a crosssectional, self-report survey design. RESULTS: Eighty-five percent of the sample reported adult trauma and 54% reported four or more childhood traumas. Moderate or higher depression and anxiety levels were present in 59% and 48% of participants, respectively. Structural equation model fit was good for sleep, pain, and general health, showing that trauma indirectly affected health variables via mental health. CONCLUSIONS: Participants endorsed substantial adult and childhood trauma, which likely had cascading effects on mental health and common primary care presenting health issues. PMID- 30291737 TI - Stimulation of the subparafascicular thalamic nucleus modulates dopamine release in the inferior colliculus of rats. AB - Although dopamine is commonly studied for its role in incentive motivation, cognition, and various neuropsychiatric disorders, evidence from Parkinson's disease (PD) patients that present auditory deficits suggest that dopamine is also involved in central auditory processing. It has been recently discovered that the subparafascicular thalamic nucleus (SPF) sends dopaminergic projections to the inferior colliculus (IC), an important convergence hub for the ascending and descending auditory pathways. In the present study, our aim was to provide neurochemical evidence that activation of SPF neurons evokes dopamine release in the IC of anesthetized rats using fast-scan cyclic and paired pulse voltammetry in combination with carbon fiber microelectrodes. Electrical stimulation of the SPF (60 and 90 Hz) evoked dopamine release in the IC in a frequency-dependent manner, with higher frequencies evoking greater amplitude dopamine responses. Optogenetic-evoked dopamine responses were similar to the effects of electrical stimulation suggesting that electrical stimulation-evoked dopamine release was not due to nonspecific activation of fibers of passage, but rather to activation of SPF cells projecting to the IC. Selective dopamine reuptake blockade enhanced the evoked dopamine response, while selective blockade of serotonin did not, confirming the selectivity of the neurochemical recordings to dopamine. Therefore, the SPF neuronal pathway functionally mediates dopamine release in the IC and thus may be involved in auditory processing deficits associated with PD. PMID- 30291739 TI - Making It Happen: Middle Managers' Roles in Innovation Implementation in Health Care. AB - BACKGROUND: Middle managers are given scant attention in the implementation literature in health care, where the focus is on senior leaders and frontline clinicians. AIMS: To empirically examine the role of middle managers relevant to innovation implementation and how middle managers experience the implementation process. METHODS: A qualitative study was conducted using the methods of grounded theory. Data were collected through semistructured interviews with middle managers (N = 15) in Nova Scotia and New Brunswick, Canada. Participants were purposively sampled, based on their involvement in implementation initiatives and to obtain variation in manager characteristics. Data were collected and analyzed concurrently, using an inductive constant comparative approach. Data collection and analysis continued until theoretical saturation was reached. RESULTS: Middle managers see themselves as being responsible for making implementation happen in their programs and services. As a result, they carry out five roles related to implementation: planner, coordinator, facilitator, motivator, and evaluator. However, the data also revealed two determinants of middle managers' role in implementation, which they must negotiate to fulfill their specific implementation roles and activities: (1) They perform many other roles and responsibilities within their organizations, both clinical and managerial in nature, and (2) they have limited decision-making power with respect to implementation and must work within the parameters set by upper levels of the organization. LINKING EVIDENCE TO ACTION: Middle managers play an important role in translating adoption decisions into on-the-ground implementation. Optimizing their capacity to fulfill this role may be key to improving innovation implementation in healthcare organizations. PMID- 30291740 TI - Cause of Death and End-of-Life Experiences in Individuals with Dementia with Lewy Bodies. AB - OBJECTIVES: To investigate the natural history, cause of death, and end-of-life experiences of individuals diagnosed with dementia with Lewy bodies (DLB). DESIGN: Twenty-question online survey administered through the Lewy Body Dementia Association. SETTING: United States. PARTICIPANTS: Caregivers, family, and friends of individuals who died in the past 5 years with a diagnosis of DLB (survey respondents: n = 658, 89% female, median age 50-69). MEASUREMENTS: The survey included 3 questions about the respondent's background and 17 about the end-of-life experiences of the person with DLB. Topics included time from symptom onset and diagnosis to death, cause of death, advance directive completion, end of-life education, hospice use, and location of death. Results were analyzed descriptively. RESULTS: Most individuals with DLB died within 5 years of diagnosis (median 3-4 years). Respondents indicated that physicians rarely discussed what to expect at the end of life (40% total, but only 22% to a helpful degree) and that the caregiver usually initiated such conversations. Death was usually expected, but fewer than half of respondents felt prepared for what to expect. Seventy-eight percent used hospice, usually at home or in skilled care, with wide variations in duration. Failure to thrive was the most common cause of death (65%), followed by pneumonia and swallowing difficulties (23%), other medical conditions (19%), and complications from falling (10%) (multiple causes allowed). CONCLUSION: Study results highlight a critical need for better prognostic counseling and education for persons and families living with DLB. The results of the current study can inform such counseling, but additional studies are needed to further explore expected prognosis of individuals diagnosed clinically with DLB and optimal use of palliative care services. PMID- 30291741 TI - Effects of psychosocial interventions on patient-reported outcomes in patients with psoriasis: a systematic review and meta-analysis. AB - BACKGROUND: Psoriasis can lead to high psychosocial burden, and the occurrence of psoriasis is related to psychological distress. OBJECTIVES: This study provides an overview of psychosocial interventions for patients with psoriasis and examines their effects on patient-reported outcomes. METHODS: A systematic search of four electronic databases (CENTRAL, MEDLINE, Embase and PsycINFO) was conducted in January 2017. All trials on psychosocial interventions for patients with psoriasis that used patient-reported outcomes and a comparison group were included. Data were extracted on intervention, study population and outcomes. Risk of bias was assessed according to the Cochrane Handbook. A meta-analysis on quality of life, depression and anxiety was performed. This review was registered on PROSPERO (CRD42016037934). RESULTS: Nineteen studies were included. Interventions primarily used cognitive behavioural or mindfulness-based techniques. Risk of bias was mostly rated 'unclear' due to nontransparent reporting (e.g. no study protocols were published, only one study reported blinding of patients). Meta-analysis using standardized mean differences between the intervention and control groups showed significant, small-to-medium effects (given with 95% confidence intervals) on quality of life (0.28, 0.04-0.51; six studies, n = 664) and anxiety (0.36, 0.15-0.57; six studies, n = 363). The effect on depression was not significant (0.37, -0.05 to 0.80; five studies, n = 326). CONCLUSIONS: Psychosocial interventions offer an effective means to improve quality of life and anxiety in patients with psoriasis. Although the importance of such psychosocial aspects for psoriasis is unquestioned, there is a lack of high-quality evaluation studies. Nontransparent reporting of risk of bias, low power and a lack of replication studies make it difficult to reach confident conclusions from the evidence.

AB - OBJECTIVES: To examine prostate-specific antigen (PSA) screening practice change in subgroups of men defined in guidelines and in various regions and to identify factors associated with change in screening practices. DESIGN: Observational study using serial cross-sections, 2003 to 2013. SETTING: National fee-for service Medicare. PARTICIPANTS: Men aged 68 and older eligible for prostate cancer screening. MEASUREMENTS: National PSA screening practices in men aged 68 and older from 2003 to 2013 and change in regional screening rates in men aged 75 and older. RESULTS: The PSA screening rate in men aged 68 and older was 17.2% in 2003, 22.3% in 2008, and 18.6% in 2013 (p < .001 for all differences); rates ended slightly lower than rates in 2003 only in men 80 and older. Racial disparities in screening became less pronounced over this period. In men aged 75 and older, change in regional screening rates varied widely, with absolute rates growing by 15 per 100 enrollees in some areas and declining by the same amount in others. Areas with high social capital, a measure associated with diffusion of new ideas, were more likely to decline; malpractice intensity and managed care penetration had no effect. CONCLUSION: Studying Medicare enrollees over time, we found little reduction in PSA screening and even increases according to race and in some regions. The heterogeneous changes across regions suggest that consistent reduction in the use of low-value care may require change strategies that go beyond evidence and guidelines to include monitoring and feedback on performance. PMID- 30291743 TI - Reduced Autobiographical Memory Specificity Among Maltreated Preschoolers: The Indirect Effect of Neglect Through Maternal Reminiscing. AB - Maternal reminiscing and preschoolers' (M = 5.00 years, SD = 1.11) autobiographical memory specificity (AMS) were examined among abusive (n = 24), neglecting (n = 78), emotionally maltreating (n = 32), and demographically similar nonmaltreating families (n = 74). Neglect was negatively associated with child AMS and the quantity of maternal elaborations. In a moderated mediation model, neglect was negatively associated with the quantity of maternal elaborations, which was positively associated with AMS when mothers reminisced in a coherent and sensitive manner (i.e., affective quality). In the context of high maternal affective quality, maternal elaborative quantity accounted for reduced AMS among neglected preschoolers. The findings extend observations of reduced AMS to neglected preschoolers and inform theoretical models of autobiographical memory development. PMID- 30291744 TI - Changes in health-related quality of life after discharge from an intensive care unit: a systematic review. AB - Quality of life after critical illness is becoming increasingly important as survival improves. Various measures have been used to study the quality of life of patients discharged from intensive care. We systematically reviewed validated measures of quality of life and their results. We searched PubMed, CENTRAL, CINAHL, Web of Science and Open Grey for studies of quality of life, measured after discharge from intensive care. We categorised studied populations as: general; restricted to level-3 care or critical care beyond 5 days; and septic patients. We included quality of life measured at any time after hospital discharge. We identified 48 studies. Thirty-one studies used the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) and 19 used the EuroQol-5D (EQ 5D); eight used both and nine used alternative validated measures. Follow-up rates ranged from 26-100%. Quality of life after critical care was worse than for age- and sex-matched populations. Quality of life improved for one year after hospital discharge. The aspects of life that improved most were physical function, physical role, vitality and social function. However, these domains were also the least likely to recover to population norms as they were more profoundly affected by critical illness. PMID- 30291745 TI - Inhaler Technique Education and Exacerbation Risk in Older Adults with Asthma or Chronic Obstructive Pulmonary Disease: A Meta-Analysis. AB - OBJECTIVES: To evaluate the effect of inhaler education programs on clinical outcomes and exacerbation rates in older adults with asthma or chronic obstructive pulmonary disease (COPD). DESIGN: Systematic review and meta analysis. SETTING AND PARTICIPANTS: Older adults with asthma or COPD, either in primary or secondary health care and pharmacy setting. MEASUREMENTS: We searched the Medline, Embase, and Central databases according to the main eligibility criteria for inclusion: systematic reviews, meta-analysis, clinical trials and quasi-experimental studies; participants aged 65 and older; education on inhaler technique and reporting of disease control and exacerbation rates. We used the Grading of Recommendations, Assessment, Development and Evaluations scale for quality assessment and used a random-effect model with Mantel-Haenszel adjustment to perform a meta-analysis. RESULTS: We included 8 studies (4 randomized, 4 quasi experimental) with a total of 1,812 participants. The most frequent type of intervention was physical demonstration of inhaler technique, training with placebo devices. Five studies showed significant reduction in exacerbation rates (pooled risk ratio=0.71, 95% confidence interval=0.59-0.86; p < .001), although effect on disease control and quality of life showed high discrepancy in the reported results, and all randomized studies revealed uncertainty in their risk of bias assessment. CONCLUSION: All interventions seemed to improve inhaler performance and clinically relevant outcomes, but a placebo device could be the most effective. There is evidence that interventions reduce exacerbation risk in older adults, although to an overall moderate degree. PMID- 30291746 TI - Orthographic-Phonological Mapping and the Emergence of Visual Expertise for Print: A Developmental Event-Related Potential Study. AB - The N1 effect is an electrophysiological marker of visual specialization for print. The phonological mapping hypothesis (Maurer & McCandliss, 2007) posits that the left-lateralized effect reflects grapheme-phoneme integration. In this event-related potential study, first (age = 7.06 years, N = 32) and third-grade readers (age = 9.29 years, N = 28) were presented with pairs of pseudowords and Armenian character strings in a novel implicit same-different paradigm. To test the phonological mapping hypothesis, stimuli were presented in visual-only and audiovisual conditions. The results demonstrated that tuning for print already emerges in first grade. Moreover, the parallel presentation of auditory stimuli enhanced the N1 effect suggesting a role of orthographic-phonological mapping in the development of specialization for print. PMID- 30291747 TI - Trends in Polypharmacy in Japan: A Nationwide Retrospective Study. AB - OBJECTIVES: To describe and examine trends in polypharmacy according to age in Japan from 2010 to 2016. DESIGN: Retrospective observational study. SETTING: Outpatient settings. PARTICIPANTS: Japanese individuals aged 20 and older. MEASUREMENTS: We analyzed pharmacy claims data that the Japanese Ministry of Health, Labor, and Welfare provided in the Survey of Medical Care Activities in Public Health Insurance from 2010 to 2016. The use of 5 or more oral prescription medications per month was defined as polypharmacy and of 10 or more as excessive polypharmacy. Regression analysis was used to estimate trends in polypharmacy with annual percentage changes. Using number of medications (polypharmacy vs excessive polypharmacy), trends in polypharmacy and crude and age-adjusted rates of polypharmacy per 1,000 persons were calculated according to year and age group (20-34, 35-49, 50-64, 65-79, >= 80). RESULTS: We analyzed 240 million pharmacy claims data. The age-adjusted monthly prevalence rate of polypharmacy increased from 85.2 to 93.8 per 1,000 persons per month and of excessive polypharmacy from 13.6 to 14.0 per 1,000 persons per month from 2010 to 2016 in the entire study population. The highest rate of polypharmacy (per 1,000 persons) was observed in 2016 in those aged 80 and older (326.8), followed by those aged 65 to 79 (167.3). The polypharmacy rate increased by 6.3% (95% confidence interval (CI)=4.0-8.7) per year from 2010 to 2012, then decreased by 0.7% (95% CI=-1.3-0.0) per year from 2012 to 2016. The rate of excessive polypharmacy increased by 4.5% (95% CI=1.1-8.0) per year from 2010 to 2013 and then decreased by 3.7% (95% CI=-6.7 to -0.6) per year from 2013 to 2016. CONCLUSION: The overall trend of polypharmacy in Japan increased during the study period, although the increase ceased in 2013 and then declined from 2013 to 2016. Policy changes in Japan might be responsible for some of the changes. PMID- 30291748 TI - Characteristics and Patterns of Marijuana Use in Community-Dwelling Older Adults. AB - OBJECTIVES: To understand patterns of marijuana use in community-dwelling older adults in Colorado. DESIGN: Anonymous survey. SETTING: Two academic geriatric primary care clinics. PARTICIPANTS: English-speaking individuals. MEASUREMENTS: We assessed self-reported characteristics and patterns of marijuana use and effect on targeted symptoms. Survey analysis focused on current users, defined as individuals who had used marijuana in the past 3 years. RESULTS: Three hundred forty-five individuals completed the survey (55% response rate); 113 (32%) had used marijuana in the past, of whom 55 (16%) had used since legalization. More than half of current users were aged 75 and older, and one-quarter were aged 85 and older. Most current users were white women. Of current users, 44% used marijuana products at least weekly for common conditions including chronic pain, depression, anxiety, and insomnia, and most found marijuana helpful for these conditions. Most respondents reported obtaining marijuana recreationally (67%) without a prescription. Nine respondents reported negative side effects attributable to marijuana use. CONCLUSION: To our knowledge, this is the first study to characterize marijuana use of older adults in a state in which it is legal for medical and recreational use. Marijuana was used for several common geriatric conditions, and respondents reported few side effects. The small number of survey respondents, the lack of generalizability in states where marijuana sales are illegal, and participation bias were the main study limitations. Further research is needed to better understand useful or harmful effects in this population. J Am Geriatr Soc 66:2167-2171, 2018. PMID- 30291749 TI - The effect of network size and sampling completeness in depauperate networks. AB - The accurate estimation of interaction network structure is essential for understanding network stability and function. A growing number of studies evaluate under-sampling as the degree of sampling completeness (proportional richness observed). How the relationship between network structural metrics and sampling completeness varies across networks of different sizes remains unclear, but this relationship has implications for the within- and between-system comparability of network structure. Here, we test the combined effects of network size and sampling completeness on the structure of spatially distinct networks (i.e., subwebs) in a host-parasitoid model system to better understand the within system variability in metric bias. Richness estimates were used to quantify a gradient of sampling completeness of species and interactions across randomly subsampled subwebs. The combined impacts of network size and sampling completeness on the estimated values of twelve unweighted and weighted network metrics were tested. The robustness of network metrics to under-sampling was strongly related to network size, and sampling completeness of interactions were generally a better predictor of metric bias than sampling completeness of species. Weighted metrics often performed better than unweighted metrics at low sampling completeness; however, this was mainly evident at large rather than small subweb size. These outcomes highlight the significance of under-sampling for the comparability of both unweighted and weighted network metrics when networks are small and vary in size. This has implications for within-system comparability of species-poor networks and, more generally, reveals problems with under-sampling ecological networks that may otherwise be difficult to detect in species-rich networks. To mitigate the impacts of under-sampling, more careful considerations of system-specific variation in metric bias are needed. PMID- 30291750 TI - Alda-1, an aldehyde dehydrogenase-2 agonist, causes deterioration in renal functions following ischemia-reperfusion injury due to crystalline nephropathy. AB - Renal ischemia-reperfusion injury (IRI) induces the production of aldehydes which are detoxified by aldehyde dehydrogenases (ALDHs). Alda-1 is a selective ALDH2 agonist and its protective effect was demonstrated in several conditions. The effect of Alda-1 on the kidney or on renal IRI was not investigated. We investigated the effect of Alda-1 on the renal dysfunction following IRI. Wistar rats underwent left IRI for 40 min. Group-Alda (n = 11) received Alda-1 starting 24 h before IRI and continued for 7 days thereafter when renal functions were measured. Group-Vx (n = 11) underwent similar protocol but received the dissolvent. Alda-1 did not affect renal blood flow or glomerular filtration rate in the left ischemic kidney in Group-Alda compared to Group-Vx (3.05 +/- 0.50 vs. 3.53 +/- 0.70, and 0.40 +/- 0.06 vs. 0.51 +/- 0.08, respectively, p > .05 for both). However, left renal fractional sodium excretion was higher in Group-Alda (2.80 +/- 0.43 vs. 1.37 +/- 0.36, p = .02). Alda-1 also adversely affected the gene expressions of kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin (217 +/- 38 vs. 99 +/- 13 and 49 +/- 13 vs. 20 +/- 5, respectively, p < .05 for both) and the alterations in tumor necrosis factor-alpha, transforming growth factor-beta1, plasminogen activator inhibitor-1, fibronectin 1 and p53 (4.4 +/- 0.9 vs. 2.1 +/- 0.3, 1.5 +/- 0.1 vs. 1.1 +/- 0.1, 30.0 +/- 2.7 vs. 11.7 +/- 2.3, 3.6 +/- 0.4 vs. 2.1 +/- 0.2 and 1.3 +/- 0.1 vs. 0.9 +/- 0.07, respectively, p <= .05 for all). This was associated with intratubular crystal deposition suggestive of crystalline nephropathy. Alda-1 exacerbated the IRI induced renal tubular dysfunction and alterations in markers of acute kidney injury, biomarkers of inflammation, fibrosis and apoptosis and this was associated with intratubular crystal deposition suggestive of crystalline nephropathy. PMID- 30291751 TI - A multicomponent approach toward understanding emotion regulation in schizophrenia. AB - OBJECTIVES: Emotion deficits are well documented in people with schizophrenia. Far less is known about their ability to implement emotion regulation strategies. We sought to explore whether people with schizophrenia can modify their emotion responses similar to controls. METHODS: People with (n = 25) and without (n = 21) schizophrenia were instructed to amplify positive-emotion expression, reappraise negative emotion experience, and suppress physiological response. Multiple components of emotion response were measured (experience, expression, and physiology). RESULTS: Although people with schizophrenia showed increased positive expressivity following amplification and decreased negative emotion experience following reappraisal, overall, they expressed less positive emotion and experienced more negative emotion compared with controls. Neither group was effective at physiological suppression. CONCLUSIONS: Together these findings suggest that people with schizophrenia can engage in amplification and reappraisal when explicitly instructed to do so, albeit additional practice may be necessary to modify emotion responses to levels similar to controls. PMID- 30291752 TI - What's in a name? Patient registration errors and their threat to transfusion safety. PMID- 30291753 TI - Soluble CD40L and CD62P levels differ in single-donor apheresis platelet concentrates and buffy coat-derived pooled platelet concentrates. AB - BACKGROUND: Platelet storage lesions are structural and biochemical changes in platelet concentrates (PCs), and depend on variables in collection and processing, as well as secondary procedures and storage conditions; such lesions can be mitigated by the use of platelet additive solutions (PASs). STUDY DESIGN AND METHODS: This study investigated release of the inflammatory markers sCD40L and sCD62P by single-donor apheresis platelet concentrates (SDA-PCs) and buffy coat-derived pooled platelet concentrates (PPCs) before and after storage. SDA-PC and PPC samples (n = 9089) processed by various methods and stored for different durations were obtained following production in one regional setting, the French National Blood Service. Soluble factors were quantified in PC supernatants immediately after processing and at the time of delivery, using biological testing technology (Luminex). RESULTS: SDA-PCs appeared more activated than PPCs at the end of the production step (i.e., prior to storage); however, proinflammatory soluble factors exhibited greater increases in PPCs than in SDA PCs during storage. In SDA-PCs, PAS-D (65%) led to reduced secretion of sCD62P, but favored secretion of sCD40L, compared with the alternative PAS-E. CONCLUSION: These data stress the importance of the production (processing) steps of PC manufacture and of storage. The extent to which they affect patient outcomes awaits further investigation in clinical studies. PMID- 30291754 TI - Cascadia Rising: thoughts on a Seattle earthquake disaster exercise. AB - BACKGROUND: The Cascadia subduction zone off the US Pacific Northwest coast produces a Force 9 earthquake once every 300 years. Cascadia Rising was a regional disaster drill modeled on such an event. Western Washington State has 5 million people and one Level I trauma center. STUDY DESIGN AND METHODS: The blood response of the trauma center and region were modeled under the conditions laid down in the disaster scenario. The scenario assumed structural damage to the 1931 reinforced concrete building housing the trauma hospital transfusion service with loss of electricity, data services, and water. The regional blood center, in a newer building located six blocks away, suffered less disruption. The regional blood inventory is in a blood component manufacturing facility 18 miles south of downtown. RESULTS: At best and at risk to life, the trauma center could issue universally compatible components at a rate of 60 components/hr from a damaged but still accessible transfusion service. Usable inventory would be expended in 4 hours with no clear mechanism and rules for resupply. The regional center has additional group O red blood cells and AB or A plasma to sustain that rate of usage for several more hours but no protocols for reestablishing communication or "push" resupply. Regional resources will be gone in less than a day. CONCLUSIONS: After a major Cascadia earthquake, blood resources may fail immediately, but even with luck, local resources used emergently at maximal issue rates will last 4 to 14 hours.(c) 2018 AABB. PMID- 30291755 TI - Blood transfusions in preterm infants: changes on perfusion index and intermittent hypoxemia. AB - BACKGROUND: Red blood cell (RBC) transfusion decreases intermittent hypoxemia (IH) events beyond the first week of life. This benefit may be related to improved perfusion to the respiratory control network. Perfusion index (PI) is a perfusion measure provided by the pulse oximeter. We hypothesized that the benefit in IH after RBC transfusion is associated with an increase in PI. In addition, we assessed the value of PI and clinical measures in predicting the effect of RBC transfusion on IH. STUDY DESIGN AND METHODS: We prospectively enrolled infants less than 30 weeks' gestation age. PI and oxygen saturation (SpO2 ) were monitored with high-resolution pulse oximeters 24 hours before and after RBC transfusion. Data were analyzed at three postnatal periods: Epoch 1, first week of life (1 to 7 days of life); Epoch 2, 2 to 4 weeks of life (8 to 28 days of life); and Epoch 3, 4 to 8 weeks of life. RESULTS: A total of 118 transfusions were analyzed. IH measures significantly decreased after transfusion in Epochs 2 and 3. PI significantly increased after transfusion, but it did not correlate with the decrease in IH measures. Mechanical ventilation, fraction of inspired oxygen (FiO2 ), and IH measures influenced the effects on oxygenation. CONCLUSIONS: RBC transfusion improved IH after the first week of life. The benefit in IH did not correlate with PI increase after transfusion. Pretransfusion respiratory support and IH measures predicted the effect of transfusion on oxygenation. PMID- 30291756 TI - Comparison of administration of platelet concentrates suspended in M-sol or BRS-A for pediatric patients. AB - BACKGROUND: Two different platelet additive solutions (PASs), M-sol and BRS-A, used in succession, have been reported as novel PASs in Japan. However, there are not enough clinical data comparing platelet concentrates (PCs) suspended in these PASs. STUDY DESIGN AND METHODS: A retrospective cohort study of consecutive cases was performed between 2013 and 2018. For the first 30 months, children with primary hematologic and/or malignant diseases were transfused resuspended PCs in M-sol (RPC-M) as plasma-replaced PCs. For the subsequent 30 months, children were transfused plasma-replaced PCs in BRS-A (RPC-B) under the same conditions. Children transfused with conventional PCs (containing residual plasma) were defined as controls. We evaluated the frequency of adverse events, corrected count increment (CCI), and bleeding occurrence in the children. RESULTS: Overall, 84 patients received 679 conventional PC transfusions. Allergic transfusion reactions (ATRs) occurred in 12 (14.3%) patients transfused with 12 (1.8%) bags. Fifty-nine patients received a total of 1182 bags of RPC-M, and one patient (1.7%) had five (0.4%) ATR episodes. During the last 30 months, 58 patients were transfused 1044 bags of RPC-B, with ATRs occurring in four (6.9%) patients transfused with four (0.4%) bags. No other adverse events were observed with either RPC-M or RPC-B. CCIs (24 hr) were not significantly different for the three different PCs, and posttransfusion bleeding was not observed. CONCLUSIONS: Plasma-replaced PC using two different PAS in children appeared to prevent ATRs accompanied without other adverse events in children. Transfusion efficacy was not significant; therefore, either of the PASs could be used with equivalent results based on the clinical situation. PMID- 30291757 TI - Early Crying, Sleeping, and Feeding Problems and Trajectories of Attention Problems From Childhood to Adulthood. AB - This study investigated if crying, sleeping or feeding problems that co-occur (multiple regulatory problems [RPs]) or are persistent predict attention problems and diagnoses of attention deficit hyperactivity disorder (ADHD) in childhood and adulthood. Participants were 342 individuals who were assessed at 5, 20, and 56 months for crying, sleeping, and feeding (RPs) and at 6, 8, and 28 years for ADHD diagnoses, attention problems, and attention span. Infants/toddlers with multiple/persistent RPs had an increased risk of receiving an ADHD diagnosis both in childhood and adulthood compared to those who never had RPs. Multiple/persistent RPs were further associated with a high-decreasing attention problems trajectory from childhood to adulthood. Interventions to alleviate early RPs may prevent the development of attention problems. PMID- 30291758 TI - Repeat whole blood donors with a ferritin level of 30 MUg/L or less show functional iron depletion. AB - BACKGROUND: Whole blood donors are screened for iron depletion through hemoglobin measurement alone or in combination with ferritin. Ferritin measurement gives the advantage of earlier detection of iron depletion. In a previous study we identified a ferritin level of 30 MUg/L or less as a possible indicator of suboptimal erythropoiesis. In this study, erythropoietic parameters were measured to determine if a ferritin level of 30 MUg/L or less is indicative of iron deficient erythropoiesis in repeat whole blood donors. STUDY DESIGN AND METHODS: Twenty-one healthy male repeat whole blood donors were divided into two groups according to their predonation ferritin values: 30 MUg/L or less (low-ferritin group) and greater than 30 MUg/L (normal-ferritin group). Ferritin and erythropoietic parameters were measured before whole blood donation and weekly in the 8 weeks after donation. RESULTS: A significantly lower value was found for hemoglobin, mean corpuscular volume (MCV), reticulocytes, and reticulocyte hemoglobin content on at least three of the nine time points in the low-ferritin group compared to the normal-ferritin group (p < 0.05). Of these parameters, MCV and reticulocyte hemoglobin content were significantly lower before donation as well as during all 8 weeks following donation (p < 0.05). CONCLUSION: Based on the lower values of the erythropoietic parameters in the low-ferritin group, it can be concluded that repeat whole blood donors with a ferritin value of 30 MUg/L or less have iron-deficient erythropoiesis and therefore require a longer donation interval than the current 56 days. PMID- 30291759 TI - Whole genome sequencing reveals rare off-target mutations and considerable inherent genetic or/and somaclonal variations in CRISPR/Cas9-edited cotton plants. AB - The CRISPR/Cas9 system has been extensively applied for crop improvement. However, our understanding of Cas9 specificity is very limited in Cas9-edited plants. To identify on- and off-target mutation in an edited crop, we described whole genome sequencing (WGS) of 14 Cas9-edited cotton plants targeted to three genes, and three negative (Ne) control and three wild-type (WT) plants. In total, 4188-6404 unique single-nucleotide polymorphisms (SNPs) and 312-745 insertions/deletions (indels) were detected in 14 Cas9-edited plants compared to WT, negative and cotton reference genome sequences. Since the majority of these variations lack a protospacer-adjacent motif (PAM), we demonstrated that the most variations following Cas9-edited are due either to somaclonal variation or/and pre-existing/inherent variation from maternal plants, but not off-target effects. Of a total of 4413 potential off-target sites (allowing <=5 mismatches within the 20-bp sgRNA and 3-bp PAM sequences), the WGS data revealed that only four are bona fide off-target indel mutations, validated by Sanger sequencing. Moreover, inherent genetic variation of WT can generate novel off-target sites and destroy PAMs, which suggested great care should be taken to design sgRNA for the minimizing of off-target effect. These findings suggested that CRISPR/Cas9 system is highly specific for cotton plants. PMID- 30291760 TI - Impact of household composition and family functioning on health of Hispanic mothers in mental health treatment: A secondary analysis study. AB - WHAT IS KNOWN ON THE SUBJECT?: Mothers with mental health problems are at risk of well-being and experience lack of support. There is little research focusing on the effect of household composition on health of Hispanic mothers with mental illness. As the family is a central feature in Hispanic lives and there is a high dependence on the family for help, it is crucial to understand how household composition and family functioning influences Hispanic mothers' health and well being. WHAT DOES THE PAPER ADDS TO EXISTING KNOWLEDGE?: Living with at least one other adult in the household are related to better Hispanic mothers' physical and psychological health. Mothers living with a greater number of adult in the house are more likely to have fatigue and depression. More family hassles are associated with worse health outcomes in Hispanic mothers with mental health problems WHAT ARE THE IMPLICATIONS FOR PRACTICE?: There is a need to assess family members who are supportive to Hispanic mothers and to address families' basic needs in the intervention. Interventions for Hispanic mothers with mental health problems should be grounded in supporting the strengths of the Hispanic familial networks. A family-centred approach for mothers with mental health problems requires integrated assessments and interventions including the families as units. ABSTRACT: Introduction Household composition is seen as a critical factor for recovery of Hispanic mothers with mental illness, but little research has examined the relationship of household composition and health. Aim This study examined how household composition and family functioning impact on both physical and psychological health of Hispanic mothers receiving outpatient mental health services. Method The study analysed baseline data of 137 Hispanic mothers participating in a randomized trial of "Healthy Home," a family-strengthening home health intervention. A bilingual (English/Spanish) research assessor interviewed participants regarding household composition, family hassles, family cohesion and mother's physical and psychological health. Results Mothers living with at least one other adult and having fewer family hassles had better health outcomes. Mothers living with a greater number of adult in the house were more likely to have fatigue and depression. Discussion Hispanic mothers having no adults to help them in the house are less able to maintain their physical and psychological health. A family-centred approach for mothers requires integrated assessments and interventions including the families as units. Implication for practice Interventions for Hispanic mothers with mental health problems should be grounded in supporting the values and strengths of the Hispanic familial networks. PMID- 30291761 TI - The psychometric properties of the Collaborative Assessment and Management of Suicidality rating scale. AB - OBJECTIVE: The CAMS Rating Scale (CRS) is an adherence measure for the Collaborative Assessment and Management of Suicidality (CAMS), a suicide-specific clinical intervention. This study examined the ability of the CRS to assess adherence to CAMS. METHODS: Video-recorded therapy sessions of clinicians delivering either CAMS or Enhanced Care-As-Usual (E-CAU) were rated with the CRS. These ratings (N = 98) were used to evaluate criterion validity, internal consistency, and factor structure. RESULTS: Criterion validity and factor analyses did not support the organization of the CRS into its current subscales. Furthermore, the identified factor model and item-level statistics revealed weak CRS items. Finally, internal consistency was higher among CAMS clinicians than among clinicians delivering E-CAU. CONCLUSION: These results establish the CRS as a measure that can effectively assess the adherence to CAMS in its current form. Potential revisions to future iterations of the CRS are discussed. PMID- 30291762 TI - Complications of a severe autoimmune hemolytic anemia crisis: transfusional iron overload and gangrenous cholecystitis. AB - BACKGROUND: Evans syndrome is a rare autoimmune disorder that is defined by the simultaneous or sequential presence of two or more cytopenias without an obvious underlying precipitating cause. Evans syndrome usually follows a chronic relapsing and remitting course and is quite rare, making it difficult to evaluate in clinical studies. CASE REPORT: A 66-year-old male patient with a 17-year history of Evans syndrome presented with fulminant autoimmune hemolytic anemia (AIHA). He presented with a markedly elevated C-reactive protein (CRP; 46 mg/L [normal, 0-5 mg/L]) before onset of a decrease in hemoglobin. He required the transfusion of 20 units of red blood cells while awaiting response to aggressive immunosuppressive therapy including high-dose corticosteroids, intravenous immunoglobin therapy, and rituximab. He achieved a complete hematologic response. RESULTS: His postdischarge course was complicated by acute cholecystitis requiring laparoscopic cholecystectomy. In addition, his transfusional iron overload requiring 16 phlebotomies to reduce his ferritin level from 4933 MUg/L to 326 MUg/L, with phlebotomies ongoing every 2 weeks to achieve a ferritin level of less than 100 MUg/L. CONCLUSION: Neither transfusional iron overload nor acute cholecystitis are well-recognized complications of a severe episode of AIHA. An elevated CRP has been recently recognized as an important prognostic marker in patients with immune thrombocytopenic purpura and this case suggests a need to evaluate its utility in AIHA. PMID- 30291763 TI - Electronic nicotine delivery system (ENDS) use in relation to mental health conditions, past-month serious psychological distress and cigarette smoking status, 2017. AB - BACKGROUND AND AIMS: Adults with mental health conditions (MHC) exhibit disproportionately high smoking prevalence and experience profound tobacco related disparities. US nationally representative surveys from 2012 to 2015 found relatively high usage of electronic nicotine delivery systems (ENDS; e.g. e cigarettes) among adults with MHC. However, research has not examined these associations specifically among never smokers. Aims were to examine associations among MHC diagnosis, serious psychological distress (SPD) and ENDS use and to test whether associations varied by cigarette smoking status. DESIGN: Cross sectional US nationally representative survey. SETTING: United States, 2017. PARTICIPANTS: A total of 5762 adults (52.0% female; 64.8% non-Hispanic white, 11.4% non-Hispanic black, 15.9% Hispanic, 7.9% non-Hispanic other). MEASUREMENTS: Outcomes were lifetime, current and current daily ENDS use. Predictors were lifetime MHC, past-month SPD and cigarette smoking status, and covariates were gender, age, race/ethnicity, education and annual household income. FINDINGS: lifetime MHC and past-month SPD were each associated with higher likelihood of having ever used ENDS (P <= 0.001), currently using ENDS (P <= 0.001) and currently using ENDS daily (P < 0.05). There were interactions between MHC and smoking status in predicting ENDS use, such that MHC status predicted higher lifetime and current ENDS use specifically among never and current smokers. Never smokers with MHC had 2.62 higher odds [95% confidence interval, (CI) = 1.54, 4.45] of current ENDS use than those without MHC. Among never smokers, those with MHC indicated higher expectations that ENDS would improve relaxation and concentration (P < 0.05). CONCLUSIONS: In 2017, US adults with versus without mental health conditions (MHC) were more likely to use electronic nicotine delivery systems (ENDS). In particular, both never and current smokers with MHC reported disproportionately high rates of current ENDS use. PMID- 30291764 TI - Amygdala subnuclei and healthy cognitive aging. AB - Amygdala is a group of nuclei involved in the neural circuits of fear, reward learning, and stress. The main goal of this magnetic resonance imaging (MRI) study was to investigate the relationship between age and the amygdala subnuclei volumes in a large cohort of healthy individuals. Our second goal was to determine effects of the apolipoprotein E (APOE) and brain-derived neurotrophic factor (BDNF) polymorphisms on the amygdala structure. One hundred and twenty-six healthy participants (18-85 years old) were recruited for this study. MRI datasets were acquired on a 4.7 T system. Amygdala was manually segmented into five major subdivisions (lateral, basal, accessory basal nuclei, and cortical, and centromedial groups). The BDNF (methionine and homozygous valine) and APOE genotypes (epsilon2, homozygous epsilon3, and epsilon4) were obtained using single nucleotide polymorphisms. We found significant nonlinear negative associations between age and the total amygdala and its lateral, basal, and accessory basal nuclei volumes, while the cortical amygdala showed a trend. These age-related associations were found only in males but not in females. Centromedial amygdala did not show any relationship with age. We did not observe any statistically significant effects of APOE and BDNF polymorphisms on the amygdala subnuclei volumes. In contrast to APOE epsilon2 allele carriers, both older APOE epsilon4 and epsilon3 allele carriers had smaller lateral, basal, accessory basal nuclei volumes compared to their younger counterparts. This study indicates that amygdala subnuclei might be nonuniformly affected by aging and that age-related association might be gender specific. PMID- 30291766 TI - Mini photopheresis for refractory chronic graft-versus-host disease in children and adolescents. AB - BACKGROUND: Extracorporeal photopheresis (ECP) has been established to treat graft-versus-host disease. Our mini ECP technique (mini-ECP) allows for treatment of patients with GVHD and contraindications for classical ECP or low body weight. The safety and efficacy of applying ECP for the long-term treatment of chronic GVHD (cGVHD) have not been described. STUDY DESIGN AND METHODS: A retrospective analysis of mini-ECP treatments for children and adolescents with cGVHD was performed. Mini-ECP with 100 to 200 mL of whole blood was used to treat 14 patients. The median age at the start of treatment was 7 years (range, 1-17 years), and median body weight was 20 kg (range, 8-53 kg). A total of 703 mini ECP treatments was performed. The median number of treatments per patient was 35 (range, 8-129), and median treatment duration was 11 months (range, 1.4-28.5 months). RESULTS: Mini-ECP was well tolerated. Four adverse events occurred in three patients, and two of them were related to the ECP procedure. Complete or partial responses were observed in 10 patients. Steroids were discontinued in seven patients and tapered in three others. Responses were seen in the skin, mouth, gastrointestinal tract, and eyes. CONCLUSION: Mini-ECP represents a less invasive ECP alternative for low-body-weight patients with cGVHD and contraindications for apheresis. PMID- 30291767 TI - In-house chemical library repurposing: A case example for Pseudomonas aeruginosa antibiofilm activity and quorum sensing inhibition. AB - Drug repurposing has become a recent trend in drug development programs, where previously developed drugs are explored for hit and redeveloped into potential therapeutic agents for new diseases. Globally, in any drug development program, a series of molecules are synthesized and evaluated for the hypothesized activity. Hits are developed into lead molecules or drugs, whereas the negative ones are shelved in the lab with no immediate use. We in this project took the previously sidelined small chemical molecules to the next level of utility, where previously developed in-house small molecules library are tested for the unexplored biological relevant activity. As biofilm formation and quorum sensing play a vital role in bacterial pathogenesis, we believe that they could be one of the most effective targets for antimicrobial agents. In this study, we report the evaluation of 50 different compounds for anti-biofilm and anti-quorum sensing activity against Pseudomonas aeruginosa. Out of the screened compounds, three hydrazine-carboxamide hybrid derivatives showed promising anti-biofilm property and inhibition of pyocyanin production without any direct antimicrobial activity and cytotoxicity issues. Hydrazine-carboxamide hybrids can be a new class and promising leads for further anti-biofilm and anti-virulence development against microbial infections.

AB - The purpose of this publication was to inform surgeons as to the modern state-of the-art evidence-based guidelines for management of the recurrent laryngeal nerve invaded by malignancy through blending the domains of 1) surgical intraoperative information, 2) preoperative glottic function, and 3) intraoperative real-time electrophysiologic information. These guidelines generated by the International Neural Monitoring Study Group (INMSG) are envisioned to assist the clinical decision-making process involved in recurrent laryngeal nerve management during thyroid surgery by incorporating the important information domains of not only gross surgical findings but also intraoperative recurrent laryngeal nerve functional status and preoperative laryngoscopy findings. These guidelines are presented mainly through algorithmic workflow diagrams for convenience and the ease of application. These guidelines are published in conjunction with the INMSG Guidelines Part I: Staging Bilateral Thyroid Surgery With Monitoring Loss of Signal. Level of Evidence: 5 Laryngoscope, 128:S18-S27, 2018.

PMID- 30291768 TI - Learning curve and surgical factors influencing the surgical outcomes during the initial experience with laparoscopic pancreaticoduodenectomy. AB - BACKGROUND: Laparoscopic pancreaticoduodenectomy (LPD) requires sufficient laparoscopic training for optimal outcomes. Our aim is to determine the learning curve and investigate the factors influencing surgical outcomes during the learning curve. METHODS: We analyzed surgical results of 150 consecutive cases of LPD performed by three hepatopancreatobiliary surgeons during their 50 first cases. Learning curves were constructed by cumulative sum (CUSUM) analysis. Preoperative factors influencing resection time and blood loss were investigated in the introductory and stable periods. RESULTS : The learning curve could be divided into three phases: initial (1-20 cases), plateau (21-30), and stable (31 50). Resection time with lymph node dissection was significantly longer during the introductory period (initial and plateau periods) (P < 0.01) but not the stable phase (P = 0.51). Multivariate analysis revealed that patients with pancreatitis had longer resection times and massive blood loss in both the introductory and stable periods (stable phase). High visceral fat area was also significantly related to massive blood loss in the introductory period (P = 0.04). CONCLUSIONS: Hepatopancreatobiliary surgeons need more than 30 cases until LPD becomes stable. Lymph node dissection and patients with high visceral fat area and concomitant pancreatitis should be avoided during the introductory period of the learning curve. PMID- 30291770 TI - Prepubertal exposure to low doses of sodium arsenite impairs spermatogenesis and epididymal histophysiology in rats. AB - For the first time, juvenile toxicity of inorganic arsenic (As) was investigated in male rats, focusing on reproductive effects. As is a metalloid naturally occurring in the environment, being the inorganic forms the most toxics. Contaminated drinking water and agricultural products are the main prospectors of intoxication for general population. In the present study, Wistar male rats (21 days old) were distributed into three groups (n = 10/group): control (received vehicle-filtered drinking water), As1 (received AsNaO2 at 0.01 mg L-1 ) and As2 (received AsNaO2 at 10 mg L-1 ). The animals were euthanized on PND 53. Testicular damages increased in As1 and As2 compared to control (ie, presence of vacuolization, acidophilic cells, and epithelium degeneration). Testicular interstitium of As1 and As2 presented fluid's increase and intense inflammatory infiltration. In the epididymis there was reduction of sperm amount in the lumen, besides epithelium areas presenting cribriform aspect in As1 and As2, exfoliation of cells in the light (in As1) and vacuoles (in As2). In epididymis interstitium, inflammatory infiltrates were observed in initial segment of As1 and As2. AsNaO2 changed immunolabeling pattern for androgen receptor in epididymis of As2, although serum testosterone levels was statistically comparable to control. Mass spectrometry revealed higher As concentrations in testis and epididymis of As2 compared to As1 and Control. These results indicate compromise of spermatogenesis and epididymal histophysiology in AsNaO2 -treated animals, possibly impairing sperm quality and fertility in long-term, even at low levels of exposure. Investigations about the reversibility of reproductive damages are necessary to better understand the mechanisms of As reproductive toxicity.

AB - Foodborne shrimp allergy events have occurred in recent years. To illustrate the mechanism of high hydrostatic pressure technology to change the allergenicity of shrimp, the major allergen tropomyosin was separated and purified from Litopenaeus vannamei, and indentified with matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS). The effect of temperature factor under high hydrostatic pressure was measured with indirect ELISA method, CD and fluorescence spectrum. The results showed that the antigenicity of TM protein had an increase after being heated at 35 or 45 C when treated at 300 MPa for 15 minutes, while the antigenicity decreased at 55, 65, and 75 C. With the increase of heat temperature, the secondary structure of TM also changed. The mutual transformation happened between the alpha-helix and beta sheet, beta-turn, and the random coil. The tertiary structure of TM was observed dynamic changes from the extended state to the folded state, and then re-extended state to re-folded state. These results suggested that high hydrostatic pressure combined with temperature could influence the antigenicity of TM by the change of conformation which would be useful as theoretical guidance on developing new methods or technologies for producing hypoallergenic shrimp products.

AB - In case of GMAW-P application, the product quality is strongly dependent on the arc plasma performances. Therefore, in order to improve the application, it is important to understand and characterize the fundamental plasma properties. In this paper, different techniques (high speed camera ,optical emission spectroscopy system, electrical data acquisition system, synchronous triggering device) were used to characterize the arc characteristic. The metal diffusion process from the peak time to the base time is discussed, as well as its physical characteristics. The results show that, in the peak time phase, a high concentration of metal vapor arc is concentrated in the plasma center of the range of about 1 mm, during the transition from the peak to the base pulse periods, the diffusion leads to an iron vapor flux from regions in the arc core to the arc fringes. The iron mol fraction of the peak time was up to 75%, only taking up 35% of the base time. PMID- 30291773 TI - [Research on Measurement Method of Gas Velocity Combined Absorption Spectroscopy Technique and Cross-Correlation]. AB - For the small frequency shift and large error of tunable diode laser absorption spectroscopy (TDLAS) velocity method based on Doppler Effect in measuring the gas velocity, velocity measurement method combined fixed wavelength absorption spectroscopy and cross correlation is proposed in this paper. Considering the characteristics of the hydrocarbon fuel combustion products, 7 158.597 cm(- 1) absorption line of H(2)O molecular was selected. Through arranging two beams of fixed wavelength absorption measurement point of upstream and downstream, the gas velocity can be calculated by analyzing the cross-correlation properties of the two signals. The flat flame burner experiment system was used in the experimental research of the velocity measurement. The change of gas velocity with time under variable working condition was obtained. Under the same condition, numerical calculation is carried out. And the measurement results are compared with the results of the numerical simulation with relative deviation less than 8%. Then the method is preliminarily applied to measure the high speed plume of the kerosene-fueled Rocket Based Combined Cycle (RBCC) engine, and the upstream and downstream fluctuant signals of detectors were obtained. The velocity of the plume was calculated with cross correlation analysis which verifies the feasibility of this method. The experimental results show that the gas velocity measurement method has a wide measuring range with high measuring accuracy and little environment interference. The method proposed in this paper provides a simple and reliable method for the measurement of engine gas velocity.

PMID- 30291775 TI - [Spectroscopic Studies on the Host Plant Selection Mechanism of Trabala vishnou gigantina Yang (Lepidoptera: Lasiocampidae)]. AB - Trabala vishnou gigantina Yang (Lepidoptera: Lasiocampidae) is a polyphagous forestry pest whose periodic breaking out results in great economic damage including total crop failure to forestry and fruit production in China. In this study, in order to improve the understanding of the host plant selection mechanism of T. vishnou gigantina larvae, locust, caragana, willow, poplar, apricot and sea-buckthorn were used as potential host plants for the test. Two way choice experiment method was used to study the T. vishnou gigantina Yang feeding preferences of the six kinds of plants. Moreover, the chemical component and physical structure of six plants were analyzed with Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD). Among the six plants, T. vishnou gigantina larvae showed a strong preference for sea-buckthorn, followed by, apricot, willow, poplar, locust, and caragana. The FTIR analysis displayed that those six plants presented similar characteristic on absorption peak position, peak amount, and shape. The targets (1 154/1 733, 1 154/898) by FTIR showed that lipids and polysaccharide were major nutriments to affect the host plant selection of T. vishnou gigantina larvae. The XRD results showed that crystallinity index (CrI) also could affect the host plant selection of T. vishnou gigantina larvae. In this research, spectroscopy technology was firstly applied to the study of interactive relationship between insect and host, which would blaze a trail for intensive study of host plant selection mechanism of insect at molecular level. PMID- 30291776 TI - [The Study on Combined Screening Method for TBS and Cervical Cancer Cell's DNA Quantitative Analysis Based on Multi-Spectral Imaging Technology]. AB - The traditional screening method of cervical cancer mainly involves TBS classification method and quantitative analysis method based on DNA, TBS screening method which has high diagnostic rate, but it needs experienced doctors to participate in the process with low sensitivity. Therefore, it is difficult to achieve early cervical cancer screening; cell's DNA quantitative analysis, only stained the nucleus, achieving a quantitative and automated analysis. Even with high sensitivity, the specificity is poor. So it is extremely necessary to realize the combination of screening for TBS and cell's DNA quantitative analysis, but the current TBS and DNA quantitative analysis combined screening method for the use of two different cell smear, time-consuming, laborious and very inconvenient, there is no screening method for cervical cancer on a combination of TBS and DNA quantitative analysis at home and abroad. This paper presents a method using TBS classification and DNA quantitative analysis on the same cell smear which was stained with Pap and Feulgen in order to solve the problem of the interference of the absorbance of DNA substance caused by multiple staining. a set of multi spectral imaging system and DNA absorbance peeling model are established based on linear multiple regression. With model solution, the real absorbance of the substance DNA was calculated, and the quantitative analysis of DNA was carried out. A pseudo color image is synthesized from 3 - band cell images with the close wavelength of RGB for TBS classification, so the organic combination of TBS and cell's DNA quantitative analysis is realized. Experiments show that the DNA quantitative analysis model of this method is stable, with small error and high diagnostic rate due to the fact that the pseudo color images used for TBS screening were bright, clear, and clear cytoplasm. Therefore, this method is very useful in the diagnosis and screening of cervical cancer. PMID- 30291777 TI - [Rapid Diagnosis of Sound, Yellow and Citrus Greening Leaves with Hyperspectral Imaging]. AB - The feasibility was investigated for identifying sound, yellow and citrus greening leaves of navel orange trees based on hyperspectral imaging combined with correlation analysis and discriminant partial least square (DPLS) methods. The hyperspectral data of sound, yellow and citrus greening leaves were recorded in the wavelength range of 374.28~1 016.89 nm. Two regions of interest (ROI) were marked symmetrically on both sides along main veins with an ellipse of major axis of 60 pixels and minor axis of 30 pixels. The average reflectance spectrum was extracted from ROI regions. A pair wavelengths of 502.79 and 374.28 nm were chosen with correlation analysis method in the wavelength range of 374.28~1 016.89 nm. The classification model was developed with the peak ratio of the pair wavelengths. This model was effective to sound leaves with the recognition accuracy of 1.7% but yellow and citrus greening leaves. The DPLS model was employed with the preprocessing spectra of second derivative and Savitzky-Golay smoothing. The recognition accuracy of this model was 100% for citrus greening leaves and yellow ones. The number of latent variables (LVs) was optimized with the leave one out cross validation method. The optimal LVs, correlation coefficient and standard error of calibration of the DPLS model were 17, 0.96 and 0.13, respectively. The correction classification rate of the DPLS model was 100% for yellow leaves and citrus greening ones. Two-step method of the peak ratio models combination with the DPLS was proposed for identifying sound, yellow and citrus greening leaves. The new samples were applied to evaluation the classification ability of the two-step method, which included sound leaves of 10, citrus greening leaves of 10 and yellow leaves of 10. The correction classification rate reached 96.7%. Experimental results showed that it was feasible to identify sound, yellow and citrus greening leaves by hyperspectral imaging coupled with the peak ratio and DPLS models. PMID- 30291778 TI - Molecular mechanisms of non-thermal plasma-induced effects in cancer cells. AB - Plasma is the fourth state of matter with higher energy than gas; non-thermal plasma (NTP) is currently available. As NTP is useful in sterilization, promoting wound healing and cancer treatments, the molecular mechanisms of plasma-induced effects in living cells and microorganisms are of significant interest in plasma medicine with medical-engineering collaboration. Molecular mechanisms of plasma induced effects in cancer cells will be described in this minireview. Both direct and indirect methods to treat cancer cells with NTP have been developed. NTP interacts directly with not only cancer cells but also the liquids surrounding cancer cells and the immune cells that target them. Reactive oxygen and nitrogen species play key roles in NTP-induced effects; however, other mechanisms have been suggested. The complex interactions between NTP, cells and liquids have been extensively studied. In the future, details regarding NTP-induced effects on gene regulatory networks, signaling networks, and metabolic networks will be elucidated. PMID- 30291779 TI - Microbial transglutaminase for biotechnological and biomedical engineering. AB - Research on bacterial transglutaminase dates back to 1989, when the enzyme has been isolated from Streptomyces mobaraensis. Initially discovered during an extensive screening campaign to reduce costs in food manufacturing, it quickly appeared as a robust and versatile tool for biotechnological and pharmaceutical applications due to its excellent activity and simple handling. While pioneering attempts to make use of its extraordinary cross-linking ability resulted in heterogeneous polymers, currently it is applied to site-specifically ligate diverse biomolecules yielding precisely modified hybrid constructs comprising two or more components. This review covers the extensive and rapidly growing field of microbial transglutaminase-mediated bioconjugation with the focus on pharmaceutical research. In addition, engineering of the enzyme by directed evolution and rational design is highlighted. Moreover, cumbersome drawbacks of this technique mainly caused by the enzyme's substrate indiscrimination are discussed as well as the ways to bypass these limitations. PMID- 30291780 TI - FAM134B promotes adipogenesis by increasing vesicular activity in porcine and 3T3 L1 adipocytes. AB - Family with sequence similarity 134, Member B (FAM134B), is a cis-Golgi transmembrane protein that is known to be necessary for the long-term survival of nociceptive and autonomic ganglion neurons. Recent work has shown that FAM134B plays a pivotal role in autophagy-mediated turnover of endoplasmic reticulum (ER) membranes, tumor inhibition and lipid homeostasis. In this study, we provide mechanistic links between FAM134B and ARF-related protein 1 (ARFRP1) and further show that FAM134B resides in the Golgi apparatus. Here, we found that FAM134B increased lipid accumulation in adipocytes. Transport vehicle number and ADP ribosylation factor (ARF) family gene expression were also increased by FAM134B overexpression, suggesting that vesicular transport activity enhanced lipid accumulation. ARF-related protein 1 (ARFRP1) is a GTPase that promotes protein trafficking. We show that FAM134B regulates the expression of ARFRP1, and the knockdown of ARFRP1 abolishes enhancement on lipid accumulation caused by FAM134B. In addition, FAM134B upregulates the PAT family protein (PAT), which associates with the lipid droplets (LDs) surface and promotes lipolysis by recruiting adipocyte triglyceride lipase (ATGL). These findings indicate that FAM134B promotes lipid accumulation and adipogenic differentiation by increasing vesicle transport activity in the Golgi apparatus and inhibiting the lipolysis of LDs. PMID- 30291781 TI - Formylglycine-generating enzymes for site-specific bioconjugation. AB - Site-specific bioconjugation strategies offer many possibilities for directed protein modifications. Among the various enzyme-based conjugation protocols, formylglycine-generating enzymes allow to posttranslationally introduce the amino acid Calpha-formylglycine (FGly) into recombinant proteins, starting from cysteine or serine residues within distinct consensus motifs. The aldehyde bearing FGly-residue displays orthogonal reactivity to all other natural amino acids and can, therefore, be used for site-specific labeling reactions on protein scaffolds. In this review, the state of research on catalytic mechanisms and consensus motifs of different formylglycine-generating enzymes, as well as labeling strategies and applications of FGly-based bioconjugations are presented. PMID- 30291782 TI - Non-invasive improved technique for lumbar discus hernia classification based on fuzzy logic. AB - This paper presents the improved technique for classification of the type of lumbar discus hernia based on fuzzy logic. The reduced mobility of the foot is one of the symptoms of the disease that occurs because of the displaced discs in the space of two vertebrae. This fact was used for non-invasive discus hernia diagnosis by measuring force values from four sensors placed on both feet (first, second and fourth metatarsal head as well as the heel). Hardware and software systems were constructed for the doctor to perform the measurements and have a graphical representation during the measuring procedure. The procedure included measuring force values of 18 subjects during normal standing, standing on forefeet and heels. All subjects were diagnosed by a specialist with either L4/L5 or L5/S1 discus hernia. Filtering and further preprocessing of acquired values included separation of forefeet and heel segments that were used as inputs to fuzzy system. The results showed that the accuracy of such a fuzzy system was around 72%, and the proposed system correctly recognizes healthy individuals. Obtained information about forces on characteristic points on the foot represents useful data in diagnosis which further can be processed in order to be a supportive tool to doctors.

AB - Background Diabetes has previously been linked to mental health problems in children and adolescents, but more recent studies have yielded mixed findings. The aim of the current study was to compare symptoms of mental health problems in children and adolescents with and without type 1 diabetes (T1DM). Methods Life quality, subjective well-being, self-rated health, depression and somatic symptoms in children and adolescents with diabetes (n=130) were measured and compared to the results of a socio-demographically joined control group (n=177) which consists of healthy children and adolescents. Results A significant difference could be observed between the groups in well-being and depressive symptoms as according to the results, the research sample namely the children with T1DM could be described with significantly higher subjective well-being and mood, but with less physical symptoms and lower level of depression as those in the control group. Conclusions These findings suggest that T1DM is not associated with an increased risk of psychosocial problems, and confirm that even a severe disease of a child can lead to personal growth. PMID- 30291786 TI - Influence of climate and environmental change in Nigeria: a review on vulnerability and adaptation to climate change. AB - This paper reviews the current issues that involve environmental changes in Nigeria and environmental threats within the country. The fundamental aim of scientific knowledge in environmental studies is to reconcile climate change and environmental sustainability with developmental goals. Therefore, information on impact adaptation to climate change and vulnerability research is required to develop specific, action-oriented, interdisciplinary, successful, sociopolitical and democratic reform for the entire population of a country. This condition requires large inclusion of environmental researchers, institutions, re-inventing of research structures and ideas to dominate the global environmental change research and the critical analysis of present decision making, power, structure and related information structures. This review presents the effect of climate change in Nigeria and encourages adaptation research with challenging innovation, such as the use of energy-efficient renewable energy sources to significantly reduce greenhouse gas emissions. This paper also highlighted the need for researchers to become detailed, action oriented and multiscalar and to attend communications structure problems in enhancing the environmental activity. PMID- 30291787 TI - Rats selectively bred for showing divergent behavioral traits in response to stress or novelty or spontaneous yawning with a divergent frequency show similar changes in sexual behavior: the role of dopamine. AB - Sexual behavior plays a fundamental role for reproduction in mammals and other animal species. It is characterized by an anticipatory and a consummatory phase, and several copulatory parameters have been identified in each phase, mainly in rats. Sexual behavior varies significantly across rats even when they are of the same strain and reared under identical conditions. This review shows that rats of the same strain selectively bred for showing a divergent behavioral trait when exposed to stress or novelty (i.e. Roman high and low avoidance rats, bred for their different avoidance response to the shuttle box, and high and low novelty exploration responders rats, bred for their different exploratory response to a novel environment) or a spontaneous behavior with divergent frequency (i.e. low and high yawning frequency rats, bred for their divergent yawning frequency) show similar differences in sexual behavior, mainly in copulatory pattern, but also in sexual motivation. As shown by behavioral pharmacology and intracerebral microdialysis experiments carried out mainly in Roman rats, these sexual differences may be due to a more robust dopaminergic tone present in the mesocorticolimbic dopaminergic system of one of the two sub-lines (e.g. high avoidance, high novelty exploration, and low yawning rat sub-lines). Thus, differences in genotype and/or in prenatal/postnatal environment lead not only to individual differences in temperament and environmental/emotional reactivity but also in sexual behavior. Because of the highly conserved mechanisms controlling reproduction in mammals, this may occur not only in rats but also in humans. PMID- 30291788 TI - Prognostic Value and Clinicopathologic Features of Platelet Distribution Width in Cancer: A Meta-Analysis. AB - BACKGROUND The association between platelet distribution width (PDW) and cancer has been evaluated by a few studies, but the influence of PDW on cancer prognosis is unclear. Therefore, we conducted the present meta-analysis. MATERIAL AND METHODS We identified relevant research using identical search strategies. The influence of PDW level on cancer prognosis, as well as clinical characteristics, was analyzed. RESULTS A total of 11 studies comprising 2625 cancer patients were included in our meta-analysis. The results suggested that high PDW level was obviously related to poor OS (HR=1.54, 95%CI 1.18-2.00), especially for breast cancer (HR=1.21, 95%CI 1.07-1.36) and pharyngolaryngeal cancer (HR=3.06, 95%CI 1.68-5.57). Furthermore, high PDW was obviously related to poor OS both in older and younger subgroups, with combined HR estimates of 1.58 (95%CI 1.15-2.16) and 1.64 (95%CI 1.19-2.26), respectively. High PDW level was notably related to poor OS in the cut-off value 316% subgroup (HR=1.84, 95%CI 1.01-3.40). Moreover, high PDW level was obviously associated with lymph node metastasis (OR=1.43, 95%CI 1.04-1.99). CONCLUSIONS The findings of this study suggest that PDW is an effective and convenient indicator of cancer prognosis. Furthermore, high PDW level is obviously associated with lymph node metastasis. PMID- 30291789 TI - Comparing outcomes of concurrent chemotherapy regimens in patients 65 years old or older with locally advanced oropharyngeal carcinoma. AB - BACKGROUND: The comparative efficacy of cisplatin (CDDP), carboplatin, and cetuximab (CTX) delivered concurrently with radiation for locally advanced oropharyngeal squamous cell carcinoma continues to be evaluated. METHODS: The linked Surveillance, Epidemiology, and End Results-Medicare database was used to identify and compare patient and disease profiles, mortality, toxicity, and overall cost for patients with oropharynx cancer undergoing definitive concurrent chemoradiation with CDDP, carboplatin, or CTX between 2006 and 2011. The human papillomavirus status was unknown. The primary outcome was 2-year overall survival (OS). RESULTS: Four hundred nine patients receiving concurrent CDDP (n = 167), carboplatin (n = 69), or CTX (n = 173) were included. Those who were older, those who were nonwhite, and those with a Charlson Comorbidity Index >= 2 were less likely to receive CDDP. Two-year OS was inferior with CTX (hazard ratio [HR], 1.68; 95% confidence interval [CI], 1.08-2.60; P = .020) and no different with carboplatin (HR, 1.31; 95% CI, 0.73-2.35; P = .362) in a Cox proportional hazards model (reference CDDP). There was no statistically significant difference between carboplatin and CTX (HR, 1.28; 95% CI, 0.77-2.14; P = .891). Rates of antiemetic use and hospital visits for nausea/emesis/diarrhea or dehydration were statistically higher with CDDP. Pneumonia rates were higher with carboplatin. In the multivariate model, the corrected mean per-patient spending was significantly higher for CTX and carboplatin than CDDP ($61,133 and $65,721 vs $48,709). CONCLUSIONS: Patients who received CDDP had improved OS. CDDP was also associated with slightly lower overall costs and higher antiemetic usage and hospital visit rates, although a strong selection bias was observed because those receiving CTX and carboplatin were older and had higher comorbidity scores. PMID- 30291790 TI - FNA of epithelioid sarcoma: Curie Institute experience and critical review of the literature. AB - BACKGROUND: Epithelioid sarcoma (ES) is a rare mesenchymal tumor that is divided into 2 types: classic and proximal. To the authors' knowledge, ES has been poorly studied in cytology, with fewer than 50 cases reported to date. The objective of the current study was to analyze the cytological and immunohistochemical information regarding 5 cases of ES. METHODS: Five cases of ES were analyzed: 4 of proximal type and 1 of classic type. The cases were taken from 4 female patients and 1 male patient. The patients ranged in age from 10 to 75 years. RESULTS: All smears obtained from the proximal type of ES were found to be hypercellular with a necrotic and inflammatory background. Smears from classic type ES were hypocellular with a hemorrhagic background. Large, dispersed epithelioid cells and loosely cohesive groups of cells were most frequently noted in all cases. All cases of proximal-type ES demonstrated rhabdoid cells and marked nuclear atypia, but in only one case were rhabdoid cells found to be dominant. ES diagnoses were confirmed by immunohistochemistry in histological material. In 4 cases, epithelial marker expression was noted, whereas CD34 was found to be positive in only the classic type of ES. In 2 cases, total loss of SMARCB1/INI1 nuclear expression was observed. In the 2 SMARCB1/INI1-positive cases, loss of SMARCA2/BRM expression was observed in one case and partial loss was observed in the other case. CONCLUSIONS: The proximal type of ES differs from the classic type by the presence of rhabdoid cells and marked nuclear atypia. A specific immunohistochemical profile demonstrating loss of SMARCB1/INI1 or other proteins from the SWI/SNF complex also may be indicative of this diagnosis. PMID- 30291791 TI - Optimal treatment of early stage HER2-positive breast cancer. AB - Significant advances have occurred in the treatment of human epidermal growth factor receptor 2 (HER2)-positive breast cancer that have changed its natural history. The addition of trastuzumab to standard therapy has dramatically improved the prognosis for patients with early stage, HER2-positive breast cancer to unprecedented survival outcomes. Yet, long-term follow-up data from adjuvant pivotal trials indicate that 15-24% of patients still develop recurrent disease. Most of the research has focused on the addition of novel anti-HER2 drugs to standard therapy, including studies evaluating the monoclonal antibody pertuzumab; the antibody-drug conjugate trastuzumab-emtansine (T-DM1); the selective, reversible HER2/epidermal growth factor receptor kinase inhibitor lapatinib; or the irreversible pan-HER2 inhibitor neratinib. Dual HER2 blockade has improved overall survival remarkably in metastatic breast cancer; however, in patients with early stage disease, it has led to small benefits in progression free survival. Moreover, biologic heterogeneity within HER2-positive disease may determine response to treatment and prognosis. Different subgroups of patients with HER2-positive breast cancer may benefit from different therapeutic approaches. Thus, there is ongoing work to optimize and de-escalate treatment in patients who may do just as well with less therapy and can avoid unnecessary treatments and their related toxicities. The objective of this review is to summarize the background and latest evidence on the current management of early stage, HER2-positive breast cancer and to present novel perspectives on its management. PMID- 30291792 TI - Toward the potential cure of leukemias in the next decade. AB - Historically, progress in leukemia research has been slow, but it has accelerated recently as a result of understanding the pathophysiology of leukemias and implementing more effective and targeted therapies. This review summarizes the progress across leukemia subsets and projects the potential cure of most leukemias in the next decade. PMID- 30291794 TI - A Single Extracellular Vesicle (EV) Flow Cytometry Approach to Reveal EV Heterogeneity. AB - Extracellular vesicles (EVs) actively participate in intercellular communication and pathological processes. Studying the molecular signatures of EVs is key to reveal their biological functions and clinical values, which, however, is greatly hindered by their sub-100 nm dimensions, the low quantities of biomolecules each EV carries, and the large population heterogeneity. Now, single-EV flow cytometry analysis is introduced to realize single EV counting and phenotyping in a conventional flow cytometer for the first time, enabled by target-initiated engineering (TIE) of DNA nanostructures on each EV. By illuminating multiple markers on single EVs, statistically significant differences are revealed among the molecular signatures of EVs originating from several breast cancer cell lines, and the cancer cell-derived EVs among the heterogeneous EV populations are successfully recognized. Thus, our approach holds great potential for various biological and biomedical applications. PMID- 30291793 TI - Klinefelter syndrome in males with germ cell tumors: A report from the Children's Oncology Group. AB - BACKGROUND: Males with Klinefelter syndrome (KS) (47,XXY) may be more likely to develop germ cell tumors (GCTs), particularly mediastinal GCTs. To date, there are no reports characterizing the prevalence of KS among male GCT cases. METHODS: The authors used array genotyping data from a Children's Oncology Group epidemiology study to estimate the prevalence of KS in males with GCTs (433 males aged birth-19 years). Using Fisher's exact tests, the authors examined differences in age at diagnosis, race/ethnicity, tumor location and histology, and several birth characteristics between cases of KS-GCT and GCT cases without chromosomal abnormalities. Using publicly available data, the authors estimated the 1-year risk, risk ratio, and corresponding 95% confidence interval of GCTs among KS cases. RESULTS: Based on analysis of array genotyping data, 3% of male GCT cases (13 cases) had KS. The additional X chromosome was of maternal origin in 7 of the 13 cases. Of these 13 KS cases, 5 of 9 KS-GCT cases with parental questionnaire data (56%) reported a diagnosis of KS. No significant differences were observed with regard to patient or birth characteristics between KS-GCT and non-KS-GCT cases. KS-GCT cases were significantly more likely to be diagnosed with mediastinal tumors than non-KS-GCT cases (P<.01). The authors estimated the risk of developing a GCT among males with KS to be 0.00025, or 1 per 4000 males (risk ratio, 18.8; 95% confidence interval, 11.7-30.0). CONCLUSIONS: Compared with males without chromosomal abnormalities, males with KS are more likely to be diagnosed with a mediastinal GCT. The presence of KS should be considered in males with a diagnosis of mediastinal GCT. In the current study, the authors report that approximately one-third of males with mediastinal germ cell tumors have Klinefelter syndrome, and therefore screening of these individuals for the syndrome may be warranted. Males with Klinefelter syndrome are 19 times as likely as males without Klinefelter syndrome to develop germ cell tumors. PMID- 30291795 TI - Intermolecular Dehydrative Coupling and Intramolecular Cyclization of Ruthenium Vinylidene Complexes Formed from Aromatic Propynes Containing Carbonyl Functionalities. AB - A remarkable intermolecular dehydrative coupling reaction with the formation of a C-C bond was found for the vinylidene complex 2 a, yielding the dinuclear bisvinylidene complex 4 a. Complex 2 a containing 1-hydroxyindan moiety was first formed from the reaction of o-propynyl benzaldehyde 1 a with [Ru]-Cl ([Ru]=Cp(PPh3 )2 Ru) by a cyclization process. For analogous aldehyde 1 b containing an additional 1,3-dioxolane group on the aryl ring, similar intermolecular coupling yields the dinuclear bisvinylidene complex 4 b. However, the fluoro group on the aryl ring in aldehyde 1 c inhibits the coupling reaction, giving only the vinylidene complex 2 c. For the reactions of [Ru]-Cl in MeOH with compounds 1 f, 1 g and 1 h, each with a ketone functionality, cyclization gives vinylidene complexes 2 f, 2 g and 2 h, respectively. However, no similar intermolecular coupling was observed, instead, the intramolecular dehydration yields 8 f, 8 g and 8 h, respectively. In CDCl3 , catalytic cyclization is observed for the o-propynylphenyl ketone 1 h with [Ru]-Cl at 50 degrees C giving the isochromene products 14 h. Furthermore, treatment of the o-propynylaryl alpha,beta-unsaturated ketones 1 k-m and 1 n with [Ru]-Cl in MeOH affords the corresponding vinylidene complexes 10 k-m and 11 n each with 1-benzosuberone moiety in the presence of NH4 PF6 . These intramolecular cyclization products were formed by the addition of Cbeta onto the terminal carbon of the alkene moiety. All these reaction products were characterized by spectroscopic methods. In addition, structures of complexes 4 a, and 10 l were confirmed by single crystal X-ray diffraction analysis. PMID- 30291796 TI - Phase 1 study of EGFR-antisense DNA, cetuximab, and radiotherapy in head and neck cancer with preclinical correlatives. AB - BACKGROUND: Cetuximab combined with radiation therapy (RT) is an evidence-based treatment for locally advanced head and neck squamous cell carcinoma (HNSCC); however, locoregional failure remains the primary cause of cancer-related death in this disease. Intratumoral injection of epidermal growth factor receptor (EGFR)-antisense plasmid DNA (EGFR-AS) is safe and has been associated with promising lesional responses in patients who have recurrent/metastatic HNSCC. For the current study, the authors investigated the antitumor effects of cetuximab and EGFR-AS in preclinical HNSCC models and reported their phase 1 experience adding intratumoral EGFR-AS to cetuximab RT. METHODS: Antitumor mechanisms were investigated in cell line and xenograft models. Phase 1 trial eligibility required stage IVA through IVC HNSCC and a measurable lesion accessible for repeat injections. Patients received standard cetuximab was for 9 weeks. EGFR-AS was injected weekly until they achieved a lesional complete response. RT was delivered by conventional fractionation for 7 weeks, starting at week 3. Research biopsies were obtained at baseline and week 2. RESULTS: When added to cetuximab, EGFR-AS decreased cell viability and xenograft growth compared with EGFR-sense control, partially mediated by reduced EGFR expression. Six patients were enrolled in the phase 1 cohort. No grade 2 or greater EGFR-AS-related adverse events occurred. The best lesional response was a complete response (4 patients), and 1 patient each had a partial response and disease progression. EGFR expression decreased in 4 patients who had available paired specimens. CONCLUSIONS: In preclinical models, dual EGFR inhibition with cetuximab and EGFR AS enhanced antitumor effects. In a phase 1 cohort, intratumoral EGFR-AS injections, cetuximab, and RT were well tolerated. A phase 2 trial is needed to conduct an extended evaluation of safety and to establish efficacy. PMID- 30291797 TI - Multimedia psychoeducation for patients with cancer who are eligible for clinical trials: A randomized clinical trial. AB - BACKGROUND: Supporting patients' decision making about clinical trials may enhance trial participation. To date, few theory-based interventions have been tested to address this issue. The objective of the current study was aimed to evaluate the effect of a multimedia psychoeducation (MP) intervention, relative to a print education (PE) intervention, on patients' decision support needs and attitudes about clinical trials. METHODS: Patients with cancer who were eligible for participation in a National Cancer Institute therapeutic cancer clinical trial were recruited through the nationwide University of Rochester Cancer Center National Cancer Institute Community Oncology Research Program from 2014 to 2016 and were randomized to the MP or PE intervention. Assessments at baseline (before intervention), postintervention, and at a 2-month follow-up visit included patients' decision support needs, attitudes regarding clinical trials, and clinical trial participation. RESULTS: In total, 418 patients with various types of cancer were recruited (ages 26-89 years). Relative to the PE intervention, the MP intervention did not significantly affect decision support needs. However, patients in the MP arm reported significantly more positive attitudes about clinical trials and were more likely to participate in a clinical trial than those in the PE arm (69% vs 62%; P = .01). Furthermore, an improvement in attitudes about clinical trials significantly mediated the effect of the intervention on participation in clinical trials. CONCLUSIONS: The MP intervention was able to improve patient attitudes toward clinical trials compared with the PE intervention, and this improvement led to increased rates of participation in trials. The MP intervention could be disseminated to improve attitudes about clinical trials among patients with cancer. PMID- 30291798 TI - Individualized survival prediction for patients with oropharyngeal cancer in the human papillomavirus era. AB - BACKGROUND: Accurate, individualized prognostication in patients with oropharyngeal squamous cell carcinoma (OPSCC) is vital for patient counseling and treatment decision making. With the emergence of human papillomavirus (HPV) as an important biomarker in OPSCC, calculators incorporating this variable have been developed. However, it is critical to characterize their accuracy prior to implementation. METHODS: Four OPSCC calculators were identified that integrate HPV into their estimation of 5-year overall survival. Treatment outcomes for 856 patients with OPSCC who were evaluated at a single institution from 2003 through 2016 were analyzed. Predicted survival probabilities were generated for each patient using each calculator. Calculator performance was assessed and compared using Kaplan-Meier plots, receiver operating characteristic curves, concordance statistics, and calibration plots. RESULTS: Correlation between pairs of calculators varied, with coefficients ranging from 0.63 to 0.90. Only 3 of 6 pairs of calculators yielded predictions within 10% of each other for at least 50% of patients. Kaplan-Meier curves of calculator-defined risk groups demonstrated reasonable stratification. Areas under the receiver operating characteristic curve ranged from 0.74 to 0.80, and concordance statistics ranged from 0.71 to 0.78. Each calculator demonstrated superior discriminatory ability compared with clinical staging according to the seventh and eighth editions of the American Joint Committee on Cancer staging manual. Among models, the Denmark calculator was found to be best calibrated to observed outcomes. CONCLUSIONS: Existing calculators exhibited reasonable estimation of survival in patients with OPSCC, but there was considerable variability in predictions for individual patients, which limits the clinical usefulness of these calculators. Given the increasing role of personalized treatment in patients with OPSCC, further work is needed to improve accuracy and precision, possibly through the identification and incorporation of additional biomarkers. PMID- 30291799 TI - OSCP subunit of mitochondrial ATP synthase: role in regulation of enzyme function and of its transition to a pore. AB - The permeability transition pore (PTP) is a latent, high-conductance channel of the inner mitochondrial membrane. When activated, it plays a key role in cell death and therefore in several diseases. The investigation of the PTP took an unexpected turn after the discovery that cyclophilin D (the target of the PTP inhibitory effect of cyclosporin A) binds to FO F1 (F)-ATP synthase, thus inhibiting its catalytic activity by about 30%. This observation was followed by the demonstration that binding occurs at a particular subunit of the enzyme, the oligomycin sensitivity conferral protein (OSCP), and that F-ATP synthase can form Ca2+ -activated, high-conductance channels with features matching those of the PTP, suggesting that the latter originates from a conformational change in F-ATP synthase. This review is specifically focused on the OSCP subunit of F-ATP synthase, whose unique features make it a potential pharmacological target both for modulation of F-ATP synthase and its transition to a pore. PMID- 30291800 TI - Enrollment on clinical trials does not improve survival for children with acute myeloid leukemia: A population-based study. AB - BACKGROUND: It is questionable whether enrollment on clinical trials offers any survival advantage at the population level over standard-of-care treatment. The objectives of this study were to describe the impact of trial enrollment on event free survival and overall survival in pediatric acute myeloid leukemia (AML) using the Cancer in Young People in Canada (CYP-C) database. METHODS: Children were included if they had had AML newly diagnosed between ages birth and 14 years from 2001 to 2012. CYP-C is a national pediatric cancer population-based database that includes all cases of pediatric cancer diagnosed and treated at 1 of the 17 tertiary pediatric oncology centers in Canada. Univariate and Cox proportional hazards models were used to evaluate the impact of initial trial enrollment on survival. RESULTS: In total, 397 eligible children with AML were included in the analysis, of whom 94 (23.7%) were enrolled on a clinical trial at initial diagnosis. The most common reason for non-enrollment was that no trial was available. The event-free survival rate at 5 years was 57.8% +/- 5.2% for those enrolled versus 54.8% +/- 2.9% for those not enrolled (P = .75). The overall survival rate at 5 years was 70.1% +/- 4.9% for those enrolled versus 66.3% +/- 2.8% for those not enrolled (P = .58). Enrollment on a trial was not associated with improved event-free or overall survival in multiple regression analyses. CONCLUSIONS: Enrollment on a clinical trial was not associated with improved survival for children with AML in a population-based cohort. Rationale for trial enrollment should not include the likelihood of benefit compared with non enrollment. PMID- 30291801 TI - Respiratory emergency department use from diagnosis through survivorship in children, adolescents, and young adults with cancer. AB - BACKGROUND: Children and adolescents and young adults (AYAs) with cancer often experience severe respiratory morbidity and mortality from the therapies used to treat their cancers. Few studies have examined respiratory outcomes among this population using emergency department (ED) visits as an objective measure of respiratory health. METHODS: ED visits for respiratory conditions were identified for children and AYAs diagnosed with cancer, 0-25 years of age, from 1997 through 2012 (2535 cases) and compared with a birthdate-matched and sex-matched cohort without cancer drawn from the general population (7605 controls). Negative binomial regression with robust standard errors was used to estimate incidence rates, rate ratios (RRs), and 95% confidence intervals for primary respiratory ED visits, combined and by diagnosis (asthma, respiratory disease, and respiratory infection) from 1997 through 2015. Analyses were performed for new cases (0 to <5 years from diagnosis) and survivors (5-18 years from diagnosis). RESULTS: Subjects were followed for an average of 8 years (range, 0-18 years). Relative to the comparison cohort, cancer cases had higher incidence rates for all types of respiratory ED visits over both follow-up times. New cases had significantly higher RRs for any respiratory condition (RR, 4.14), respiratory disease (RR, 4.62), and respiratory infection (RR, 4.74). Among survivors, the RRs for any respiratory condition (RR, 2.00) and respiratory infection (RR, 2.10) were significantly elevated, although the magnitude tended to decline in survivorship. Demographic and clinical risk factors found to be associated with respiratory ED visits included Hispanic/other race/ethnicity, male sex, exposure to chemotherapy, diagnosis at a younger age, and a diagnosis of leukemia. CONCLUSIONS: The results of the current study demonstrated that children and AYAs with cancer face an increased burden of respiratory complications compared with a comparison cohort without cancer from diagnosis through survivorship. PMID- 30291803 TI - MicroRNA-146a sponge therapy suppresses neointimal formation in rat vein grafts. AB - The long-term failure of vein grafts due to neointimal hyperplasia remains a difficult problem in cardiovascular surgery. Exploring novel approaches to prevent neointimal hyperplasia is important. MicroRNA-146a (miR-146a) plays an essential role in promoting vascular smooth muscle cell (VSMC) proliferation. Thus, the aim of the present study is to investigate whether adenovirus-mediated miR-146a sponge (Ad-miR-146a-SP) gene therapy could attenuate neointimal formation in rat vein grafts. (Ad-miR-146a-SP) was constructed to transfect cultured VSMCs and grafted veins. To improve the efficiency of transferring the miR-146a sponge gene into the grafted veins, 20% poloxamer F-127 gel incorporated with 0.25% trypsin was used to increase adenovirus contact time and penetration. miR-146a-SP transduction significantly reduced the expression of miR-146a both in cultured VSMCs and vein grafts. miR-146a sponge markedly attenuated VSMC proliferation and migration. Consistent with this, miR-146a sponge gene therapy significantly attenuated neointimal formation and also improved blood flow in the vein grafts. Mechanistically, we identified the Kruppel-like factor 4(KLF4) as a potential downstream target gene of miR-146a in vein grafts. Our data show that miR-146a sponge gene therapy could effectively reduce miR-146a activity and attenuate neointimal formation in vein grafts, suggesting its potential therapeutic application for prevention of vein graft failure.

PMID- 30291804 TI - A prospective comparison of cancer clinical trial availability and enrollment among adolescents/young adults treated at an adult cancer hospital or affiliated children's hospital. AB - BACKGROUND: Low cancer clinical trial (CCT) enrollment may contribute to survival disparities affecting adolescents and young adults (AYAs) (ages 15-39 years). The objective of this study was to evaluate whether differences in CCT availability related to treatment site could explain the low CCT enrollment. METHODS: This prospective, observational cohort study was conducted at an academic children's hospital and its affiliated but geographically separated adult cancer hospital within a National Cancer Institute-designated Comprehensive Cancer Center. For consecutive, newly diagnosed AYA patients, it was determined whether an appropriate CCT existed nationally, was available at the treatment site, and was used for enrollment. Proportions of AYAs in these categories were compared between sites using the chi-square test. RESULTS: One hundred fifty-two consecutive AYA patients were included from the children's hospital (n = 68; ages 15-20 years) and the adult cancer hospital (n = 84; ages 18-39 years). Although there was no difference in CCT existence for individual AYA patients by site (children's hospital [36 of 68 patients; 52.9%] vs adult cancer hospital [45 of 84 patients; 53.6%]; P = .938), CCT availability was significantly lower at the adult cancer hospital (14 of 84 patients [16.7%] vs 30 of 68 [44.1%] at the children's hospital; P < .001). The proportion of AYAs enrolled was low at both sites (8 of 68 patients [11.8%] vs 6 of 84 patients [7.1%], respectively; P = .327). Fewer existing CCTs were available at the adult cancer hospital (4 of 27 patients [14.8%] vs 8 of 14 patients [57.1%], respectively), and those were directed toward solid tumors and new agents. CONCLUSIONS: Efforts to improve low CCT enrollment among AYAs should be differentiated by treatment site. In the adult setting, these efforts should be aimed at improving CCT availability by overcoming site-level barriers to opening existing CCTs. PMID- 30291805 TI - Perioperative biobehavioral interventions to prevent cancer recurrence through combined inhibition of beta-adrenergic and cyclooxygenase 2 signaling. AB - Evidence suggests that excess perioperative activation of the sympathetic nervous system and the consequent release of catecholamines (ie, epinephrine and norepinephrine) in the context of cancer surgery and inflammation may significantly facilitate prometastatic processes. This review first presents biomedical processes that make the perioperative timeframe pivotal in determining long-term cancer outcomes nonproportionally to its short duration (days to weeks). Then, it analyzes the various mechanisms via which the excess release of catecholamines can facilitate the progression of cancer metastases in this context by directly affecting the malignant tissues and by regulating, via indirect pathways, immunological and other mechanisms that affect metastatic progression in the tumor microenvironment and systemically. In addition, this review addresses the need to supplement beta-adrenoreceptor blockade with cyclooxygenase 2 inhibition, especially during surgery and shortly thereafter, because similar mechanisms are simultaneously activated by surgery-induced inflammatory responses. Importantly, this review presents translational and clinical evidence showing that perioperative beta-adrenoreceptor blockade and cyclooxygenase 2 inhibition can reduce the prometastatic process and cancer recurrence, and the clinical feasibility and safety of this approach are demonstrated as well. Lastly, alternative psychophysiological approaches to the use of beta-adrenergic blockers are presented because a substantial portion of patients have medical contraindications to this pharmacological treatment. The adaptation of existing psychophysiological interventions to the perioperative period and principles for constructing new approaches are discussed and exemplified. Overall, pharmacobehavioral interventions, separately or in combination, could transform the perioperative timeframe from being a prominent facilitator of metastatic progression to an opportunity for arresting or eliminating residual disease, potentially improving long-term survival rates in cancer patients. PMID- 30291806 TI - Investigation of the Reaction Pathways of Biomass-Derived Oxygenate Conversion into Monoalcohols in Supercritical Methanol with CuMgAl-Mixed-Metal Oxide. AB - Reaction pathways for the conversion of cellulose into C2 -C6 monoalcohols by supercritical methanol depolymerization and hydrodeoxygenation (SCM-DHDO) over a CuMgAl oxide catalyst have been elucidated using a range of model compounds. SCM DHDO of intermediate oxygenates including glycerol, methyl lactate, and 1,2 ethanediol produces similar products as those produced from the SCM-DHDO of cellulose. The pathway to C2 -C6 monoalcohols occurs through rapid C-C coupling reactions between methanol and diols followed by C-C scission between vicinal alcohol groups to produce two monoalcohols. Methyl-branched monoalcohols are produced through a methyl shift in a secondary diol followed by dehydration. Esters are produced by dehydrogenative coupling between an adsorbed methoxy and a primary alcohol. Both dehydrogenation to a ketone and esterification to a methyl ester are in equilibrium with the corresponding alcohol and were reversible. Dehydration of diols is the slowest observed reaction and not a main pathway to monoalcohols. SCM-DHDO of glucose, dihydroxyacetone, and cellulose all produced similar high molecular weight species indicating that condensation of intermediates can produce undesired side products. PMID- 30291807 TI - Will my child do better if she enrolls in a clinical trial? AB - The question of whether children with cancer who enroll in clinical trials have superior outcomes compared with those who do not participate has been pursued for more than 4 decades, and recent studies have provided conflicting answers. Whether clinical trial participation influences outcome has important implications for how clinicians should present trial participation to patients and families. Methodological challenges limit generalizations about the impact of clinical trial participation on outcome compared with nonparticipation. Oncologists should inform patients and families that clinical trials are the engine for future progress because they identify more effective therapies and that clinical trial participation is a reasonable option to consider for children with cancer. However, as noted in by Truong and colleagues in this issue, the rationale for trial enrollment should not include an expectation of better outcomes compared with nonenrollment. PMID- 30291808 TI - Phytochemicals as mediators for host range expansion of a native invasive forest insect herbivore. AB - Mountain pine beetle (MPB) has recently invaded jack pine forests in western Canada. This invasion signifies a climate change-induced range expansion by a native insect. The mechanism underlying this invasion is unknown, but likely involves phytochemicals that play critical roles in MPB biology. Thus far, studies have investigated the compatibility of jack pine chemistry with beetles and their microbial symbionts. I have identified three phytochemical mechanisms that have likely facilitated the host range expansion of MPB. First, jack pine chemistry is overall similar to that of the historical hosts of MPB. In particular, jack pine chemistry is compatible with beetle pheromone production, aggregation on host trees and larval development. Furthermore, the compatibility of jack pine chemistry maintains beneficial interactions between MPB and its microbial symbionts. Second, compared with historical hosts, the novel host not only has lower concentrations of toxic and repellent defense chemicals, but also contains large concentrations of chemicals promoting host colonization by MPB. These patterns are especially pronounced when comparing novel hosts with well defended historical hosts. Finally, before MPBs arrived in jack pine forests, they invaded a zone of hybrids of novel and historical hosts that likely improved beetle success on jack pine, as hybrids show chemical characteristics of both hosts. In conclusion, the phytochemistry of jack pine has likely facilitated the biological invasion of this novel host by MPB. PMID- 30291809 TI - Role of clathrin-mediated endocytosis in the use of heme and hemoglobin by the fungal pathogen Cryptococcus neoformans. AB - Heme is a major source of iron for pathogens of humans, and its use is critical in determining the outcome of infection and disease. Cryptococcus neoformans is an encapsulated fungal pathogen that causes life-threatening infections in immunocompromised individuals. C. neoformans effectively uses heme as an iron source, but the underlying mechanisms are poorly defined. Non-iron metalloporphyrins (MPPs) are toxic analogues of heme and are thought to enter microbial cells via endogenous heme acquisition systems. We therefore carried out a mutant screen for susceptibility against manganese MPP (MnMPP) to identify new components for heme uptake in C. neoformans. We identified several genes involved in signalling, DNA repair, sugar metabolism, and trafficking that play important roles in susceptibility to MnMPP and in the use of heme as an iron source. We focused on investigating the role of clathrin-mediated endocytosis (CME) and found that several components of CME including Chc1, Las17, Rvs161, and Rvs167 are required for growth on heme and hemoglobin and for endocytosis and intracellular trafficking of these molecules. We show that the hemoglobin uptake process in C. neoformans involves clathrin heavy chain, Chc1, which appears to colocalise with hemoglobin-containing vesicles and to potentially assist in proper delivery of hemoglobin to the vacuole. Additionally, C. neoformans strains lacking Chc1, Las17, Rvs161, or Rvs167 were defective in the elaboration of several key virulence factors, and a las17 mutant was avirulent in a mouse model of cryptococcosis. Overall, this study unveils crucial functions of CME in the use of heme iron by C. neoformans and reveals a role for CME in fungal pathogenesis. PMID- 30291810 TI - Synchrotron radiation microtomography of brain hemisphere and spinal cord of a mouse model of multiple sclerosis revealed a correlation between capillary dilation and clinical score. AB - Multiple sclerosis is a neurological disorder in which the myelin sheaths of axons are damaged by the immune response. We report here a three-dimensional structural analysis of brain and spinal cord tissues of a mouse model of multiple sclerosis, known as experimental autoimmune encephalomyelitis (EAE). EAE-induced mice were raised with or without administration of fingolimod, which is used in the treatment of multiple sclerosis. Brains and spinal cords dissected from the EAE mice were lyophilized so as to reconstitute the intrinsic contrast of tissue elements, such as axons, in X-ray images. Three-dimensional structures of the brain hemispheres and spinal cords of the EAE mice were visualized with synchrotron radiation microtomography. Microtomographic cross sections reconstructed from the X-ray images revealed dilation of capillary vessels and vacuolation in the spinal cord of the EAE mice. Vacuolation was also observed in the cerebellum, suggesting that the neuroinflammatory response progressed in the brain. The vessel networks and vacuolation lesions in the spinal cords were modelled by automatically tracing the three-dimensional image in order to analyze the tissue structures quantitatively. The results of the analysis indicated that the distribution of vacuolations was not uniform but three-dimensionally localized. The mean vessel diameter showed a linear correlation with the clinical score, indicating that vasodilation is relevant to paralysis severity in the disease model. We suggest that vasodilation and vacuolation are related with neurological symptoms of multiple sclerosis.

AB - BACKGROUND: Cardiovascular disease (CVD) risk is an important health concern among survivors of breast cancer. However, few studies to date have examined whether trajectories of CVD risk and major risk factors are worse among women with a breast cancer diagnosis compared with those without. METHODS: Changes in weight, body mass index, waist circumference, systolic blood pressure, and 10 year CVD risk were compared between women with (813 women) and without (1049 women) an incident breast cancer diagnosis while they were enrolled in the National Institute of Environmental Health Sciences Sister Study cohort. Blood pressure and adiposity measures were collected by trained examiners at an enrollment visit (>=1 year before breast cancer diagnosis) and a second home visit 4 to 11 years later (>=1 year after breast cancer diagnosis). The non laboratory-based Framingham risk score, a measure of 10-year general CVD risk, was calculated at both the enrollment and second visits. All analyses were stratified by menopausal status at the time of enrollment. RESULTS: Women who were premenopausal at the time of enrollment experienced moderate increases in weight, waist circumference, systolic blood pressure, and CVD risk over the study period. Those who were postmenopausal at the time of enrollment demonstrated little change in weight, but were found to have increases in waist circumference, systolic blood pressure, and CVD risk. In both groups, changes over time did not differ significantly according to breast cancer status. Neither chemotherapy nor endocrine therapy were found to be associated with greater increases in CVD risk or risk factors. CONCLUSIONS: In the current study cohort, changes over time in CVD risk, adiposity measures, and blood pressure were similar between women who developed an incident breast cancer and those who did not. PMID- 30291811 TI - Self-reported fatigue in children with advanced cancer: Results of the PediQUEST study. AB - BACKGROUND: Pediatric cancer-related fatigue is prevalent and significantly impairs health-related quality of life, yet its patterns and correlates are poorly understood. The objectives of this study were to describe fatigue as prospectively reported by children with advanced cancer and to identify the factors associated with fatigue and associated distress. METHODS: Children (age >=2 years) with advanced cancer (N = 104) or their parents at 3 academic hospitals reported symptoms at most weekly over 9 months using the computer-based Pediatric Quality of Life Evaluation of Symptoms Technology (PediQUEST) system. PediQUEST administered a modified version of the Memorial Symptom Assessment Scale (PQ-MSAS) as part of a randomized controlled trial. Clinical information was abstracted from medical records. Primary outcomes were: 1) fatigue prevalence (yes/no response to PQ-MSAS fatigue item) and 2) fatigue distress (composite score of severity, frequency, and bother). Multivariable models were constructed to identify factors independently associated with fatigue prevalence and scores reflecting fatigue distress (ie, burden). RESULTS: Of 920 reports, 46% (n = 425) noted fatigue. When reported, fatigue was of high frequency in 41% of respondents (n = 174), severity in 25%of respondents (n = 107), and bother in 34%of respondents (n = 143). Most reports (84%; n = 358) were associated with scores indicating fatigue distress. In multivariable analyses, fatigue was associated with older age, lower hemoglobin, and distress from particular symptoms (anorexia, nausea, sleep disturbance, sadness, and irritability). In contrast, fatigue distress was associated with distress from nausea, cough, and pain. CONCLUSIONS: Fatigue is common among children with advanced cancer and is often highly distressing. Interventions focused on uncontrolled symptoms may ease fatigue distress in children with advanced cancer. PMID- 30291813 TI - Validating the predictors of outcomes after radical cystectomy for bladder cancer. AB - BACKGROUND: An assessment of surgical risk is essential for patient counseling and decision making, and it can provide rationale adjustment for patient populations as health care moves from a fee-for-service to a value-based reimbursement model. The modified Frailty Index (mFI) has been proposed as a risk stratification tool for radical cystectomy (RC), and the objective of the current study was to validate this potential use of the mFI using an institutional cohort. METHODS: A retrospective review of all patients who underwent RC for bladder cancer was conducted at the authors' institution from 2012 to 2016. In addition to detailed clinicopathologic and treatment parameters, patients were categorized according to the mFI, the Charlson Comorbidity Index (CCI), and the American Society of Anesthesiologists (ASA) classification. Covariates were analyzed to determine associations with 1-month complication rates (according to the Clavien-Dindo system), 3-month readmission rates, hospitalization length, and hospitalization costs. RESULTS: In total, 346 patients were included in the analysis. The overall complication rate was 56.6%, the major (Clavien grade >=3) complication rate was 19.4%, and the readmission rate was 27.9%. Receiver operating curve analysis demonstrated a weak association of all indices with major complications after RC: the area under the curve was 0.535 (95% confidence interval [CI], 0.460-0.611) for the ASA classification; 0.565 (95% CI, 0.485 0.645) for the CCI score; and 0.551 (95% CI, 0.471-0.631) for the mFI. There were no significant differences in the rate of major complications when stratifying the results according to the mFI, CCI, or ASA class. Length of hospitalization and associated costs were correlated with mFI. CONCLUSIONS: Frailty was not associated with postoperative complications and provided little additional predictive ability over the ASA classification and the CCI score. Further research is required to identify patients who are likely to suffer significant complications after RC. PMID- 30291814 TI - Massive mitochondrial DNA content in diplonemid and kinetoplastid protists. AB - The mitochondrial DNA of diplonemid and kinetoplastid protists is known for its suite of bizarre features, including the presence of concatenated circular molecules, extensive trans-splicing and various forms of RNA editing. Here we report on the existence of another remarkable characteristic: hyper-inflated DNA content. We estimated the total amount of mitochondrial DNA in four kinetoplastid species (Trypanosoma brucei, Trypanoplasma borreli, Cryptobia helicis, and Perkinsela sp.) and the diplonemid Diplonema papillatum. Staining with 4',6 diamidino-2-phenylindole and RedDot1 followed by color deconvolution and quantification revealed massive inflation in the total amount of DNA in their organelles. This was further confirmed by electron microscopy. The most extreme case is the ~260 Mbp of DNA in the mitochondrion of Diplonema, which greatly exceeds that in its nucleus; this is, to our knowledge, the largest amount of DNA described in any organelle. Perkinsela sp. has a total mitochondrial DNA content ~6.6* greater than its nuclear genome. This mass of DNA occupies most of the volume of the Perkinsela cell, despite the fact that it contains only six protein coding genes. Why so much DNA? We propose that these bloated mitochondrial DNAs accumulated by a ratchet-like process. Despite their excessive nature, the synthesis and maintenance of these mtDNAs must incur a relatively low cost, considering that diplonemids are one of the most ubiquitous and speciose protist groups in the ocean.

PMID- 30291817 TI - Perspectives and perceptions of urgent and alert values in surgical pathology and cytopathology: A survey of clinical practitioners and pathologists. AB - In previous editorials, Chapman and Otis in 2011 and Layfield in 2014 have summarized much of the work responsible for establishing the concept of critical diagnoses in surgical pathology and cytopathology. Both editorials end with a list of 8 key policy points needed for an effective strategy of handling and communicating critical diagnoses. We have developed and distributed a Web-based survey to elicit clinicians' attitudes regarding many of those key policy points, such as how, when, and to whom critical diagnoses should be reported; we have allowed some level of collaboration with the clinical staff when developing our communication policies as the Association of Directors of Anatomic and Surgical Pathology (ADASP) consensus statement recommends. We have identified important areas of disagreement between pathologists and clinicians regarding what entities should be considered critical and who should be responsible for correlating histologic findings with the larger clinical context. Identifying these discordant points of view and fostering interdepartmental agreement on the best practices in the communication of critical diagnoses is an important patient care and safety issue. Chapman and Otis have also suggested the importance of increased access to accurate patient information and the clinical history, including the level of clinical suspicion of malignancy, and of forming a periodic review and quality assurance process. Here we explore methods of increasing the ability of pathologists and cytopathologists to identify unexpected diagnoses, including optimization of their workstations for better access to the electronic medical record, and we examine the progress of quality assurance methods in surgical pathology and cytopathology since the ADASP consensus statement in 2012. PMID- 30291816 TI - Molecular analysis of peripheral lung adenocarcinoma in brush cytology obtained by EBUS plus fluoroscopy-guided bronchoscopy. AB - BACKGROUND: More than 60% of patients with lung cancer are diagnosed at advanced stages. The introduction of targeted therapies requires molecular diagnosis to guide treatment. The aim of this study was to evaluate the feasibility of performing mutational analysis with brushing specimens obtained by radial miniprobe endobronchial ultrasound (R-EBUS) plus fluoroscopy-guided bronchoscopy in patients with peripheral pulmonary adenocarcinoma. METHODS: Brushing specimens were deposited on cytological slides and were conserved in Roswell Park Memorial Institute (RPMI) culture medium. DNA was isolated to perform a mutational analysis with real-time quantitative polymerase chain reaction and Sanger sequencing for epidermal growth factor receptor (EGFR) and Kirsten rat sarcoma viral oncogene homolog (KRAS). RESULTS: Thirty patients with adenocarcinoma were prospectively included. In 100% of the patients, the molecular study was viable with brushing specimens. In 16 (53.3%), KRAS or EGFR mutations were detected: 10 KRAS mutations (33.3%) and 6 EGFR mutations (20%). In a comparison with histological samples, a correlation of 86.6% was detected, and only 2 patients with wild-type results from brushing specimens presented with an EGFR mutation in histological samples. CONCLUSIONS: Brushing specimens conserved in RPMI medium and obtained by R-EBUS plus fluoroscopy-guided bronchoscopy are valid for molecular studies. They allow the detection of EGFR/KRAS mutations in patients with peripheral adenocarcinoma. In addition, invasive techniques are avoided, the risk of complications is reduced, and the obtained samples are optimized. PMID- 30291818 TI - [Study on the Relationship between Soil Emissivity Spectra and Content of Soil Elements]. AB - In this paper, based on the measurements of soil elements content and infrared spectra of 26 soil samples collected in more than 10 places, the relationship between soil emissivity in mid-infrared bands and the content of 11 soil elements including organic matters such as NO(3)-N, P, K, Ca, Mg, Cu, Fe, Mn, Zn and pH are analyzed. The bands where the soil elements content are significantly correlated with emissivity are given. And soil elements content estimation method is established based on the soil emissivity spectra with the partial least squares regression model and multiple stepwise regression model. The results show that: (1) In 8~10 MUm, the correlation coefficient (R(2)) between Ca and soil emissivity is the highest, followed by Mg, Mn and Fe, with the highest correlation coefficient of 0.85 and the lowest, 0.52. In the range of 6~8 MUm, the correlations between the contents of K, Fe, NO(3)-N, Zn and emissivity decrease gradually, with the highest correlation coefficient of 0.75 and the lowest 0.48. In 10~14 MUm, the correlation between soil elements contents and emissivity is the highest for Mn, followed successively by P and K. (2) The scatter plot of soil emissivity and pH value has a parabola relation basically. The emissivity is the highest when pH value is 7, while the emissivity decreases gradually with the gradual decrease of pH value. (3) The accuracy of the estimated soil elements content from the partial least squares regression method is higher than that from the multiple stepwise regression method. It is noted that R(2) between the measurements and the estimates for the elements of Cu, Fe and Ca from the partial least squares regression method are very high (larger than 0.9). Additionally, using the simulated emissivity spectrum in the ASTER thermal infrared bands, modeling R(2) and validation R(2) between the measurements and the estimates for the elements of Ca from the multiple stepwise regression method are high (0.774 and 0.892, respectively). Using the simulated emissivity spectrum in the MODIS infrared bands, modeling R(2) and validation R(2) for Ca and Fe are higher than 0.85, and modeling R(2) and validation R(2) for Mg, K are higher than 0.5. As a whole, the emissivity spectrum in ASTER band 10 and band 11 and MODIS bands 28, 29, 30 are more sensitive to soil elements content, and thus they are more suitable for the estimation of soil elements content. PMID- 30291819 TI - [A Study on Predicting Model of Organic Matter Contend Incorporating Soil Moisture Variation]. AB - Soil organic matter (SOM) is one of the most important measuring indexes of soil fertility. How to predict SOM spatial distribution precisely has great significance to soil carbon storage estimation and precision agriculture development. Traditional measurement of SOM, although with higher accuracy, consumes a lot of labor resources and costs long-term monitoring period, therefore, it is hard to achieve dynamic monitor of SOM. Spectroscopy technique has been used in SOM and other soil physicochemical parameters quick measurement. However spatial inversion model accuracy of SOM based on remote sensing images is relatively lower than laboratory model accuracy due to the influence of soil moisture, roughness and so on. In recent years, most studies have not eliminated the effect of moisture. Since moisture has great influence on SOM spectra reflectance, this study introduced the temporal information combined with the spectral information in order to solve this problem. Soil moisture has differences in multi period remote sensing images, and the spectra reflectance is also different. Based on the combination of reflectance from of two periods remote sensing images, the spectral index was constructed to predict SOM in this study. MODIS images of study area acquired in this study area (Blacksoil zone) because of the advantage of high temporal resolution. Spectra reflectance of MODIS images were used to analyze the effect of moisture on soil spectral reflectance, and then the spectral prediction models of SOM were built based on the comprehensive impacts of SOM and soil moisture. The results shows that: (1) the accuracy of SOM prediction model based on single image was lower without consideration of moisture effect, The Root mean square error (RMSE) of SOM prediction model were 0.591, 0.522, 0.545, 0.553, and the determination coefficient (R(2)) were 0.505, 0.614, 0.562, 0.568, 0.645 respectively based on the day of year (DOY) 117, 119, 130, 140, 143 single image. (2) Model with multi temporal images (DOY119 and 143) which considered the effect of moisture and SOM showed better predictive ability. RMSE was 0.442 while R2 was 0.723. Therefore the accuracy and stability of the model were significantly improved, and it can be used to predict the spatial distribution of SOM in regional scale. This study provides important information for regional soil fertility evaluation, soil carbon storage estimation, and precision agriculture development.

AB - The reflectance of saline soil in the downstream of No.500 reservoir in Fukang, Xinjiang province was investigated. Through filed sampling and spectral test, using the method of spectral transform, correlation analysis and a quantitative analysis were conducted on the salt and water content of the soil under different disturbance degree. A multiple linear regression model was established between the soil reflectance and soil salinity content. The results show that: first, the human disturbance has a significantly positive correlation with the soil content while it has an extremely negative correlation with the water content. The correlation coefficients are 0.961 and -0.929 respectively. Secondly, it shows that those most heavily disturbed soil reflectance is about 10%higher than the slightly disturbed, while the slightly disturbed soil reflectance is about 17% higher than the undisturbed soil. The reason is that the soil surface of barren land with a small amount of vegetation, the biological creature and soil surface crust have been destroyed. The more the disturbance is, the greater chance the surface layer would be destroyed. Meanwhile, the surface layer of soil will be lack of the crust protective; the soil salinity of the bottom rises to the surface associated with the soil moisture will quickly evaporate. The salt is concentrated to the surface layer due to both little precipitation and a lack of protection of soil crust. Thirdly, the peak wavelength location of the spectrum is increased (999, 876~979, 1 182~1 370, 1 900 nm) while the soil is taken from undisturbed to heavily disturbed conditions, which means that with the increase of disturbance, the soil becomes more sensitive in the near infrared region. What's more, the three different prediction models are established though the reflectance R, the reflectivity of the first derivative R', the reflectance R+water. According to the R(2) and the RMSE to comprehensive judge the accuracy of the model. It is found that among those established prediction models of the same soil salinity in the different levels of disturbance, the smaller the degree of human disturbance is, the higher the accuracy of model is. It is found that among all of those established prediction models, the one based on the derivative of R works the best, of which R(2) is larger than 0.983, model accuracy is improved by 5%~10% ,which means that through a derivative transformation, the linear noises in the original spectrum can be removed.

AB - The properties of material composition in swine wastewater are closely related to its potential environmental effects, and it could provide theoretical bases for formulating scientific resource management measures to study the composition of organic matter in wastewater. In the present study, swine wastewater was directly collected from waste-retention basins in various scale pig farms with a different farming scale (based on the annual pig slaughter), namely Cheng Lin (CL, 5 000), Wu Yang-gao (WYG, 2 000), Wan Gu (WG, 20 000), and Zhang Bang (ZB, 24 000), located in Yujiang County of Jiangxi Province. The main purpose of this study was to characterize dissolved organic matter (DOM) in swine wastewater using three dimensional excitation-emission matrices (3DEEM) and parallel factor analysis (PARAFAC). Results of all samples examined showed, with respect to CL and WYG farm, chemical oxygen demand (COD), total nitrogen (TN), ammonium nitrogen (NH+4), and dissolved organic carbon (DOC) concentration in swine wastewater was significantly higher than WG and ZB farm. Three DOM components, including two protein-like components (C1, C2) and one humic-like component (C3), were identified in wastewater using 3DEEM and PARAFAC. Results of linear regression showed, the fluorescence intensity of C1 linked significantly with C2 (p<0.001) and C3 (p<0.001), respectively, suggesting a same source or similar variation trend existed possibly between different DOM components. Furthermore, consistent with the variation trend of nutrient concentration in wastewater, fluorescence intensity of each DOM component in CL and WYG farm was significantly higher than WG and ZB farm. The total contribution of C1 and C2 to DOM in swine wastewater was CL (89.7%), WG (77.5%), WYG (87.9%), and ZB (72.9%), respectively, and the percentage of C3 was CL (10.3%), WG (22.5%), WYG (12.1%), and ZB (27.1%), respectively. Thus, the percentage of two protein-like components was significantly higher than humic-like in swine wastewater. Meanwhile, the fluorescence indices FI370 and humification index (HIX) of WG and ZB farm were higher than CL and WYG. In addition, Pearson correlation analysis showed that the effects of environmental parameters on fluorescence indices were different, and COD and DOC concentrations were significantly correlated with the fluorescence intensities of DOM components in swine wastewater. In summary, to a certain degree, the nutrient levels affected formation of fluorescence characteristics and DOM compositions in swine wastewater between different scale pig farms. PMID- 30291822 TI - [Measurement of Soil Organic Matter with Near Infrared Spectroscopy Combined with Genetic Algorithm and Successive Projection Algorithm]. AB - Visible near infrared spectroscopy combined with genetic algorithm and successive projection algorithm was investigated to detect soil organic matter (OM). A total of 394 soil samples were collected from Wencheng, Zhejiang province. In order to simplify calibration model, a total of 18 characteristic wavelengths were selected with using genetic algorithm and successive projections algorithm. These characteristic wavelengths were subjected to partial least squares regression (PLSR) with leave-one-out cross validation to establish calibration model of soil organic matter (OM) with coefficient of determination (R2) of 0.81, 0.83, RMSEP of 0.22, 0.20 and residual prediction deviation (RPD) of 2.31, 2.45 for the calibration set and prediction set respectively. The results showed that using genetic algorithm and successive projections algorithm can simplify the model greatly while the assessing indexes of model such as R2, RMSEP and RPD were not reduced greatly compared with indexes of model using full spectra data to develop calibration model. Therefore, genetic algorithm combined with successive projections algorithm can be used to simply the model to predict soil organic matter. PMID- 30291823 TI - [Comparative Study on Laser Induced Breakdown Spectroscopy Based on Single Pulse and Re-Heating Orthogonal Dual Pulse]. AB - In order to improve the detection sensitivity and spectral characteristic of laser-induced breakdown spectroscopy (LIBS), re-heating orthogonal dual-pulse configuration is adopted to analyze Fe, Pb, Ca and Mg contained in the sample and soil sample contained different concentrations of heavy mental Cr. Variation relationship between spectral intensity, signal-to-background(SBR) of four characteristic spectral lines FeI:404.581 nm,PbI:405.78 nm,CaI:422.67 nm and MgI:518.361 nm and time interval of two laser pulses is discussed, the best time interval of two laser pulses is obtained 1.0 MUs. In the condition of single pulse and dual-pulse, the enhancement factor of spectral intensity of four characteristic spectral lines FeI:404.581 nm,PbI:405.78 nm,CaI:422.67 nm and MgI:518.361 nm is respectively 2.23,2.31,2.42 and 2.10; The time evolution characteristic of spectral intensity of characteristic spectral lines FeI:404.581 nm and CaI:422.67 nm is considered, and also the variation relationship between spectral acquisition delay time and SBR of four characteristic spectral lines, dual-pulse can prolong decay time of spectral intensity and improve the SBR of characteristic spectral lines; time evolution characteristic of plasma temperature and electron density is compared in the condition of single pulse and dual-pulse, maximum elevation of plasma temperature is found to be 730 K, and the maximum increase of electron density is 1.8*1016 cm-3. The limits of detection of heavy mental Cr are obtained 38 and 20 MUg.g-1 respectively in condition of single and double pulse, limit of detection of Cr is reduced approximately 2 times by the condition of re-heating orthogonal dual pulse. Results above indicate that re-heating orthogonal dual-pulse can improve detection sensibility and spectral characteristic of LIBS technique, which provides an effective method for decreasing the limit of detection of elements. PMID- 30291824 TI - [Elemental Analysis of Rock with Remote Laser Induced Breakdown Spectroscopy]. AB - As a kind of spectroscopic technique, the remote laser-induced breakdown spectroscopy (Remote LIBS) can qualitatively or quantitatively measure the elemental compositions of remote targets with high-power laser and focusing optical path. In this work, a Remote LIBS system was designed and established to probe the target from 2 to 10 meters. It is characterized with Cassegrain telescope structure and automatic focusing technique. Based on this system, a method to remotely retrieve the major elemental abundance of rocks is presented. With comparative experiment, the influences on spectral signal by pulse laser energy, acquisition delay time, integration time, accumulative pulse number are analyzed to find out the optimum parameters: the wavelength of laser is 1 064 nm, pulse energy is 120 mJ, delay time is 1.5 MUs, integration time is 1 ms, and each spectrum data acquired with averaging 30 times detection. 48 pieces of rock specimens and 6 kinds of standard rock samples (shale, granite, andesite, basalt, gneiss and pegmatite) are selected for the experiment. As to the atomic spectra database, 8 characteristic spectral lines of the major elements (SiI390.55 nm,AlI394.40 nm,AlI396.15 nm,CaII396.85 nm,FeI404.6 nm,SiI500.60nm,MgI518.36nm,NaI589.59 nm) were extracted for analyses. Then a PLS model is constructed to quantitatively analyze the rock elements. 48 rock specimens were selected as the training sets to serve the model. The 6 standard samples were used to test the solved model. The testing results shows that the elemental abundance of Si and Al can be predicted accurately with average relative error of only 9.4% and 9.6% respectively. PMID- 30291825 TI - Early posttraumatic changes in coagulation and fibrinolysis systems in isolated severe traumatic brain injury patients and its influence on immediate outcome. AB - OBJECTIVE/BACKGROUND: Early coagulopathy in isolated severe traumatic brain injury occurs despite the lack of severe bleeding, shock, and fluid administration. We aimed to correlate coagulation activation/inhibition, thrombin generation and fibrinolysis with the development of acute trauma induced coagulopathy (TIC) and its effects on early mortality in isolated severe traumatic brain injury (iSTBI) patients. METHODS: A prospective screening of iSTBI patients was done for two years. History of anticoagulants, liver disease, hypotension, extracranial injuries, transfusion, brain death were excluded. TIC was defined as international normalized ratio (INR) >= 1.27 and/or prothrombin time (PT) >= 16.7 seconds and/or activated partial thromboplastin Time (aPTT) >= 28.8 seconds on admission following iSTBI. Analysis of tissue factor (TF), tissue factor pathway inhibitor (TFPI), protein C (PC), protein S (PS), thrombin/antithrombin complex (TAT), soluble fibrin monomer (sFM), tissue plasminogen activator (tPA) and plasminogen activator inhibitor-1 (PAI-1) was done. Cases were categorized as presence or absence of TIC and 20 healthy controls participants were included. RESULTS: A total of 120 cases met the inclusion criteria, aged 35.7 +/- 12.12 years, 96% males. TIC was identified in 50 (41.6%). TIC occurred independently of age, sex, Glasgow coma scale (GCS) but was associated with acidosis (60%; p = .01). Following iSTBI significant decline was seen in coagulation activation. Thrombin generation and fibrinolysis were markedly increased. TF, TFPI, PC and PS were low in TIC compared with control. Significant depletion of PS was seen in TIC versus No-TIC. TBI patients with depleted PS had an odds ratio (OR) of 7.10 (1.61-31.2) for TIC. Receiver operating characteristic curve (ROC) analysis depicted area under the curve (AUC) of 0.73 (95% confidence interval [CI] 0.63-0.84) with a cut-off of >=74 of PS (specificity 63.9%, sensitivity 72.7%). In-hospital mortality was higher in TIC group (44%) compared with no-TIC (20%) with OR of 4.73 (95% CI 1.68-13.3) and hazard ratio [HR] of 2.8 (95 % CI 1.2-6.4). CONCLUSION: Incidence of TIC in iSTBI is 41.6%, with 4.7 times odds for mortality. Traumatic brain injury causes enhanced coagulation activation, inadequate inhibition, exacerbation of thrombin generation, and subsequent increased fibrinolysis. ROC curve analysis revealed a cut-off of PS <= 74 with specificity 63.8%, sensitivity 72.7% for development of TIC.

AB - Primary cutaneous CD8+ aggressive epidermotropic cytotoxic T-cell lymphoma (CD8+ PCAETL) is a rare disease characterized by aggressive clinical course and short survival. All available data are extracted from case reports and case series. The outcome is dismal and only two reported cases were cured after several lines of therapies including stem cell transplant. We herein present the case of a patient with CD8+ PCAETL who presented with rapidly progressive skin lesions and systemic symptoms. He was treated with aggressive multiagent chemotherapy comprising cyclophosphamide, vincristine, doxorubicin, and dexamethasone alternating with high-dose methotrexate and cytarabine (hyper-CVAD). The treatment resulted in durable complete remission with no evidence of disease recurrence after 58 months of follow-up. This is the first reported case of durable remission after first line treatment.

AB - OBJECTIVE: To investigate differences in facility characteristics, patient characteristics, and outcomes between skilled nursing facilities (SNFs) that participated in Medicare's voluntary Bundled Payments for Care Improvement (BPCI) initiative and nonparticipants, prior to BPCI. DESIGN: Retrospective, cross sectional comparison of BPCI participants and nonparticipants. SETTING: SNFs. PARTICIPANTS: All Medicare-certified SNFs (N=15,172) and their 2011-2012 episodes of care for chronic obstructive pulmonary disease, congestive heart failure, femur and hip/pelvis fracture, hip and femur procedures, lower extremity joint replacement, and pneumonia (N=873,739). INTERVENTIONS: Participation in a bundled payment program that included taking financial responsibility for care within a 90-day episode. MAIN OUTCOME MEASURES: This study investigates the characteristics of bundled payment participants and their patient characteristics and outcomes relative to nonparticipants prior to BPCI, to understand the implications of a broader implementation of bundled payments. RESULTS: SNFs participating in BPCI were more likely to be in urban areas (80.8%-98.4% vs 69.5%) and belong to a chain or system (73.8%-85.5% vs 55%), and were less likely to be located in the south (13.1%-20.2% vs 35.4%). Quality performance was similar or higher in most cases for SNFs participating in BPCI relative to nonparticipants. In addition, BPCI participants admitted higher socioeconomic status patients with similar clinical characteristics. Initial SNF length of stay was shorter and hospital readmission rates were lower for BPCI patients compared to nonparticipant patients. CONCLUSIONS: We found that SNFs participating in the second financial risk-bearing phase of BPCI represented a diversity of SNF types, regions, and levels of quality and the results may provide insight into a broader adoption of bundled payment for postacute providers. PMID- 30291829 TI - Spinal Emergencies in Primary Care Practice. AB - Atraumatic spinal emergencies often present a diagnostic and management dilemma for health care practitioners. Spinal epidural abscess, cauda equina syndrome, and spinal epidural hematoma are conditions that can insidiously present to outpatient medical offices, urgent care centers, and emergency departments. Unless a high level of clinical suspicion is maintained, these clinical entities may be initially misdiagnosed and mismanaged. Permanent neurologic sequela and even death can result if delays in appropriate treatment occur. A focused, critical review of 34 peer-reviewed articles was performed to identify current data about accurate diagnosis of spinal emergencies. This review highlights the key features of these 3 pathological entities with an emphasis on appropriate diagnostic strategy to intervene efficiently and minimize morbidity.

RESULTS: Intra-rater reliability for the CLUE tool was ICC: 0.88 (95% CI: 0.71, 0.96). Inter-rater reliability for the CLUE tool was ICC: 0.90 (95% CI: 0.79, 0.95). Concurrent validity of the CLUE score (Pearson's r) was 0.79 with perometric inter-limb difference, and 0.53 with the Norman Lymphedema overall score. CONCLUSIONS: The CLUE tool shows excellent inter- and intra-rater reliability. The overall CLUE score for the upper extremity also shows moderately strong concurrent validity with objective and subjective measures. This newly developed clinical, physical assessment of upper extremity lymphedema provides standardization and a single score that accounts for multiple constructs. Next steps include evaluation of sensitivity to change, which would establish usefulness to evaluate intervention efficacy. PMID- 30291830 TI - Behind the Curve: Late-Onset Axial Spondyloarthritis. PMID- 30291831 TI - Postmarket Experience With HeartMate 3 Left Ventricular Assist Device: 30-Day Outcomes From the ELEVATE Registry. AB - BACKGROUND: The HeartMate 3 left ventricular assist device (Abbott, Chicago, IL) is designed to provide circulatory support with enhanced hemocompatibility for patients with advanced heart failure. The purpose of this study was to compare the surgical outcomes between patients treated during the European Conformity Mark (CE Mark [CEM]) clinical trial and those treated in the postmarket era. METHODS: The prospective, observational, multinational ELEVATE (Evaluating the HeartMate 3 with Full MagLev Technology in a Post-Market Approval Setting) registry includes patients receiving the HeartMate 3 following CEM approval. Outcomes of patients in the ELEVATE registry are compared with patients in the CEM trial. RESULTS: Compared with the CEM trial (N = 50), the ELEVATE registry group (N = 463) was more severely ill, with more patients classified as INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) profile 1 to 2 (32% versus 10%; p < 0.001). The CEM trial group was younger and underwent fewer concomitant valve procedures. After adjustment for differences in baseline characteristics, the 30-day survival was comparable between the ELEVATE registry and CEM trial groups (95% versus 98%; p = 0.46). Length of intensive care unit stay was similar between the ELEVATE registry (7 days) and CEM trial (6 days) groups. Most adverse event rates were comparable between the 2 groups. ELEVATE registry patients had a lower rate of cardiac arrhythmias (13% versus 28%; p = 0.009). With increasing experience, the implant technique has evolved to include more versatile approaches such as less invasive and off-pump implantation. CONCLUSIONS: The 30-day outcomes for ELEVATE registry patients are comparable despite being sicker than CEM trial patients. Adverse event rates remain low, with no cases of pump thrombosis within the first 30 days. Implant techniques have evolved to include more versatile approaches. PMID- 30291832 TI - Decreased PGC-1alpha Post-Cardiopulmonary Bypass Leads To Impaired Oxidative Stress In Diabetic Patients. AB - BACKGROUND: The mechanism of mitochondrial dysfunction following cardiopulmonary bypass (CPB) in diabetics lacks understanding. We hypothesized that impaired beta oxidation of fatty acids leads to worsened stress response in this patient population after cardiac surgery. METHODS: After IRB approval, right atrial tissue samples were collected from 35 diabetic and 33 non-diabetics pre- and post CPB. Patients with HbA1c >= 6.0 and a clinical diagnosis of diabetes mellitus were considered to be diabetic. Immunoblotting and microarray analysis were performed to assess protein and gene expression changes. Blots were quantified with ImageJ and analyzed using one-way ANOVA with multiple t-test comparisons after normalization. P-values < 0.05 were considered significant. Immunohistochemistry was performed for cellular lipid deposition assessment. RESULTS: Diabetics had significantly lower levels of PGC-1alpha pre- and post-CPB (p < 0.01 for both) compared to non-diabetics. Several upstream regulators of PGC 1alpha (SIRT1 and CREB) were significantly higher in non-diabetics pre-CPB (p = 0.01 and 0.0018, respectively). Antioxidant markers (NOX4 and GPX4), angiogenic factors (TGF-beta, NT3, and Ang1), and the anti-apoptotic factor Bcl-xL were significantly lower in diabetics post-CPB (p < 0.05). The expression of genes supporting mitochondrial energy production (CREB5 and SLC25A40) and angiogenic genes (p < 0.05) was significantly down-regulated in diabetics post-CPB. Immunohistochemistry results showed significantly increased lipid deposition in diabetic myocardial tissue. CONCLUSIONS: Decreased PGC-1alpha in diabetics may lead to impaired mitochondrial function and attenuated anti-apoptotic and angiogenic responses post-CPB. PGC-1alpha and upstream regulators could serve as a target for improving beta-oxidation in diabetics. PMID- 30291833 TI - Minimally invasive awake mitral valve surgery and cardiopulmonary bypass without general anesthesia. AB - Herein, we report the case of a 49-year-old man with a potentially fatal allergy to propofol and remifentanil who underwent awake minimally invasive mitral valve surgery with cardiopulmonary bypass using thoracic epidural anesthesia, without the need for endotracheal general anesthesia. The aim was the management of spontaneous respiration during cardiopulmonary bypass surgery in an awake patient. PMID- 30291834 TI - Postoperative Pneumonia Prevention in Pulmonary Resections: A Feasibility Pilot Study. AB - BACKGROUND: Pneumonia after pulmonary resection occurs in 5% to 12% of patients and causes substantial morbidity. Oral hygiene regimens lower the incidence of ventilator-associated pneumonias; however, the impact in patients undergoing elective pulmonary resection is unknown. We conducted a prospective pilot study to assess the feasibility of an oral hygiene intervention in this patient cohort. METHODS: Patients undergoing elective pulmonary resection were prospectively enrolled in a single-arm interventional study with time-matched controls. Participants were asked to brush their teeth with 0.12% chlorhexidine three times daily for 5 days before their operations and 5 days or until the time of discharge after their operations. Patients were eligible if they had known or suspected lung cancer and were undergoing (1) any anatomic lung resection or (2) a wedge resection with forced expiratory volume in 1 second or diffusing capacity of lung for carbon monoxide less than 50% predicted. RESULTS: Sixty-two patients were enrolled in the pilot intervention group and compared with a contemporaneous cohort of 611 patients who met surgical inclusion criteria. Preoperative adherence to the chlorhexidine toothbrushing regimen was high: median 100% (interquartile range: 87% to 100%). Postoperatively, 80% of patients continued toothbrushing, whereas 20% declined further participation. Among those who participated postoperatively, median adherence was 86% (interquartile range: 53% to 100%). There was a trend toward reduction in postoperative pneumonia: 1.6% (1 of 62) in the intervention cohort versus 4.9% (30 of 611) in the time-matched cohort (p = 0.35). The number needed to treat to prevent one case of pneumonia was 30 patients. CONCLUSIONS: This pilot study demonstrated patients can comply with an inexpensive perioperative oral hygiene regimen that may be promising for reducing morbidity (Clinical Trials Registry: NCT01446874). PMID- 30291835 TI - Early Clinical Outcomes of Hybrid Arch Frozen Elephant Trunk Repair With the Thoraflex Hybrid Graft. AB - BACKGROUND: Hybrid aortic arch surgery has evolved to include several technical variations, with most including an off-label use of a conventional thoracic endograft. We describe the early clinical outcomes of the Thoraflex Hybrid graft (Vascutek, Glasgow, Scotland) specifically designed for the treatment of complex arch and proximal descending aortic disease. METHODS: Between January 2014 and April 2017, 40 consecutive patients (66 +/- 14 years of age, 45% women) underwent hybrid aortic arch and frozen elephant trunk repair with the multibranched Thoraflex Hybrid graft at 9 Canadian centers. Surgical indications included transverse arch or proximal descending aortic aneurysm in 100%, acute dissection in 10%, chronic dissection in 43%, and acute aortic rupture in 1 patient. Antegrade cerebral perfusion and moderate hypothermia (24.3 +/- 1.8 degrees C) were employed in all cases. RESULTS: All 40 device implants were successful. The 30-day or in-hospital mortality was 5%. Stroke and transient neurological deficits occurred in 5% and 3% of patients, respectively. Two (5%) patients experienced transient spinal cord ischemia-there were no instances of permanent paraplegia. Mean follow-up was 550 +/- 328 days and late complications included type A aortic dissection in 1 patient, type B dissection in 2 patients, and further distal endografting in 2 patients. Survival at 30 days, 1 year, and 2 years was 95%, 95%, and 90%, respectively. CONCLUSIONS: Hybrid aortic arch and frozen elephant trunk repair with the Thoraflex Hybrid graft appears to be associated with good clinical outcomes, despite being early in the learning curve with this graft. Further investigation with this device is warranted to establish its role within the variations of hybrid arch repair. PMID- 30291836 TI - Characterization of recombinant monoclonal antibody charge variants using WCX chromatography, icIEF and LC-MS/MS. AB - Charge heterogeneity is an important aspect of research into the development of monoclonal antibody drugs. In the present study, charge variants were separated into four fractions using weak cation exchange chromatography and were thoroughly analyzed using liquid chromatography-mass spectrometry at multiple levels. Molecular weight analysis of intact antibody and subunits confirmed the presence of heavy-chain leader sequences, light-chain leader sequences, dehydration, and cysteinylation. Peptide mapping of the fractions using different enzymes further localized the modified sites. Modified proportions identified at peptide level were compared with the purity detected by imaged capillary isoelectric focusing, the results showed that basic variant 1 consisted of cysteinylation and dehydration of asparagine, and basic variant 2 fully accounted for the N-terminal leader sequence of the heavy chain. About 14.8% of the acidic variant can be explained by N-terminal leader sequences in the light chain, and 18% of the acidic variant was demonstrated to be deamidation of asparagine in the heavy chain. There was approximately 54.2% of the acidic variant still cannot be explained. It was hypothesized that those acidic variants that have not yet been identified are an ensemble of molecules with slight molecular weight differences or the same molecular weight but different structures. PMID- 30291837 TI - Polymerase assays for lead discovery: An overall review of methodologies and approaches. AB - Polymerases represent an attractive molecular target for antibacterial drug development, antiviral intervention and cancer therapy. Over the past decade, academic groups and scientists from pharmaceutical industry have developed a large plethora of different functional assays to monitor the enzymatic reaction catalyzed by polymerases. These assays were used to enable high-throughput screening (HTS) for lead discovery purposes, as well as hit-to-lead (H2L) drug profiling activities. In both cases the choice of the assay technology is critical and to the best of our knowledge, there is no review available to help scientists to choose the most suitable assay. This review summarizes the most common functional assays developed to monitor the enzymatic activity of polymerases and discusses the advantages and disadvantages of each assay. Assays are presented and evaluated in term of cost, ease of use, high-throughput screening compatibility and liability towards delivering false positives and false negatives. PMID- 30291838 TI - Oligomerization and carbohydrate binding of glucan phosphatases. AB - Glucan phosphatases are a unique subset of the phosphatase family that bind to and dephosphorylate carbohydrate substrates. Family members are found in diverse organisms ranging from single-cell red algae to humans. The nature of their functional oligomerization has been a source of considerable debate. We demonstrate that the human laforin protein behaves aberrantly when subjected to Size Exclusion Chromotography (SEC) analysis due to interaction with the carbohydrate-based matrix. This interaction complicates the analysis of laforin human disease mutations. Herein, we show that SEC with Multi-Angle static Light Scattering (SEC-MALS) provides a method to robustly define the oligomerization state of laforin and laforin variants. We further analyzed glucan phosphatases from photosynthetic organisms to define if this interaction was characteristic of all glucan phosphatases. Starch EXcess-four (SEX4) from green plants was found to lack significant interaction with the matrix and instead exists as a monomer. Conversely, Cm-laforin, from red algae, exists as a monomer in solution while still exhibiting significant interaction with the matrix. These data demonstrate a range of oligomerization behaviors of members of the glucan phosphatase family, and establish SEC-MALS as a robust methodology to quantify and compare oligomerization states between different proteins and protein variants in this family. PMID- 30291839 TI - Role of bleeding recognition and evaluation in Black-White disparities in endometrial cancer. AB - BACKGROUND: Advanced stage at diagnosis is an independent, unexplained contributor to racial disparity in endometrial cancer. OBJECTIVE: We sought to investigate whether, prior to diagnosis, provider recognition of the cardinal symptom of endometrial cancer, postmenopausal bleeding, differs by patient race. STUDY DESIGN: Black and White women diagnosed with endometrial cancer (2001 through 2011) from Surveillance, Epidemiology, and End Results-Medicare who had at least 2 years of claims prior to diagnosis were identified. Bleeding diagnoses along with procedures done prior to diagnosis were captured via claims data. Multinomial logistic regression was used to evaluate the association of race with diagnostic workup and multivariate models built to determine the association of appropriate diagnostic procedures with stage at diagnosis. RESULTS: In all, 4354 White and 537 Black women diagnosed with endometrial cancer were included. Compared to White women, Black women were less likely to have guideline concordant care: postmenopausal bleeding and appropriate diagnostic evaluation (70% vs 79%, P < .001), with adjusted relative risk ratios of 1.12-1.73 for different nonguideline-concordant pathways: bleeding without diagnostic procedures, alternative bleeding descriptions, and neither bleeding nor procedures. These pathways were associated with higher odds of advanced stage at diagnosis (adjusted odds ratio, 1.90-2.88). CONCLUSION: The lack of recognition and evaluation of postmenopausal bleeding is associated with advanced stage at diagnosis in endometrial cancer. Older Black women are at highest risk for the most aggressive histology types, yet they are less likely to have guideline concordant evaluation of vaginal bleeding. Efforts aimed at improving recognition among patients and providers-of postmenopausal bleeding in Black women could substantially reduce disparities in endometrial cancer. PMID- 30291840 TI - A US population-based study of uterine fibroid diagnosis incidence, trends, and prevalence: 2005 through 2014. AB - BACKGROUND: Despite considerable public health burden, uterine fibroid population based incidence estimates are few. Secular trends over time are even more limited. OBJECTIVE: We sought to evaluate the incidence, 10-year secular trends, and prevalence of uterine fibroid diagnoses and describe the proportion of symptomatic women. STUDY DESIGN: We performed a retrospective population-based cohort study of women, aged 18-65 years, enrolled 2005 through 2014 in Kaiser Permanente Washington. Uterine fibroid diagnoses identified by International Classification of Diseases, Ninth Revision codes and potential covariates were extracted from computerized databases. Women with prior hysterectomy and, for incidence estimates, women with prior fibroid diagnoses were excluded. Linear trends in incidence rates over the 10-year study period were evaluated using Poisson regression models. Rates and trend tests were examined for all women, by age groups, and by race/ethnicity. RESULTS: Associated International Classification of Diseases, Ninth Revision symptom-related codes were observed in 90% of incident cases. Incidence rates for fibroid diagnoses were highest for the age group 45-49 years, 240.3 per 10,000 woman-years in 2014, and for black women across all years. Overall age-adjusted estimated incidence rates declined during the 10-year study interval, from 139.4 per 10,000 woman-years in 2005 to 101.4 in 2014 (P value trend .0008). Overall prevalence in 2014 was 9.6%, and was highest among women aged 50-54 years (15.9%). Black women had higher prevalence (18.5%) than other racial/ethnic groups. CONCLUSION: We found a decreasing trend of new uterine fibroid diagnoses among predominantly symptomatic women ages 18-65 years in a recent 10-year interval. This finding was due, perhaps in part, to secular trends of decreasing hysterectomies. Nonetheless, uterine fibroids remain a common health burden, with a prevalence of nearly 10%. Rates are disproportionately high and occur at younger ages for black women, and possibly for other non-white racial/ethnic groups. These findings are of concern, as current available long-term medical therapies remain limited. PMID- 30291841 TI - A first step to improving maternal mortality in a low-literacy setting; the successful use of singing to improve knowledge regarding antenatal care. AB - BACKGROUND: Preventable maternal mortality is related to delays in recognizing the problem, transport to a facility, and receiving appropriate care on arrival. Reducing maternal mortality in low-literacy settings is particularly challenging. In the rural villages of Nepal, the maternal mortality rate is among the highest in the world; the reasons include illiteracy and lack of knowledge of the needs of pregnant women. Culturally, singing and dancing are part of Nepalese daily life and present an opportunity to transmit knowledge of antenatal care and care at birth with a view to reducing the first 2 delays. OBJECTIVE: We hypothesized that health messages regarding the importance of antenatal care and skilled birth assistance would be effectively transmitted by songs in the limited literacy environment of rural Nepal. STUDY DESIGN: We randomly grouped 4 rural village development committees comprising 36 villages into 2 (intervention and control) clusters. In the intervention group, local groups were invited to write song lyrics incorporating key health messages regarding antenatal care to accompany popular melodies. The groups presented their songs and dances in a festival organized and judged by the community. The winning songs were performed by the local people in a song and dance progression through the villages, houses, and fields. A wall chart with the key health messages was also provided to each household. Knowledge of household decision makers (senior men and women) was assessed before and after the intervention and at 12 months using a structured questionnaire in all households that also assessed behavior change. RESULTS: Structured interviews were conducted at baseline, immediately postintervention in the control and intervention areas (intervention n = 735 interviews, control n = 775), and at 12 months in the intervention area only (n = 867). Knowledge scores were recorded as the number of correct items out of 36 questions at baseline and postintervention, and of 21 questions at follow-up. Postintervention, test score doubled in the intervention group from a mean of 11.60/36-22.33/36 (P < .001), with no practically significant change in the control population (17.48/36 18.26/36). Improvement was greatest among the most illiterate members of the community (6.8/36-19.8/36, P < .001). At 12 months follow-up, a majority of the participants (63.9%) indicated that they provided information learned from the songs to their neighbors and friends, and 41.3% reported still singing the songs from the intervention. CONCLUSION: The use of songs bypassed the limitations of literacy in communicating health messages that are key to improving maternal care in this low-literacy rural setting within a developing country. The improvements were maintained without further intervention for 12 months. With appropriate sociocultural adaptation to local contexts, this low-cost method of community education may be applicable to improving maternal health knowledge and behavior change in other low-resource and limited literacy settings that may lead to reductions in maternal mortality. PMID- 30291842 TI - Epidemiology and risk factors of asthma-chronic obstructive pulmonary disease overlap in low- and middle-income countries. AB - BACKGROUND: Asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO) represents the confluence of bronchial airway hyperreactivity and chronic airflow limitation and has been described as leading to worse lung function and quality of life than found with either singular disease process. OBJECTIVE: We aimed to describe the prevalence and risk factors for ACO among adults across 6 low- and middle-income countries (LMICs). METHODS: We compiled cross-sectional data for 11,923 participants aged 35 to 92 years from 4 population-based studies in 12 settings. We defined COPD as postbronchodilator FEV1/forced vital capacity ratio below the lower limit of normal, asthma as wheeze or medication use in 12 months or self-reported physician diagnosis, and ACO as having both. RESULTS: The prevalence of ACO was 3.8% (0% in rural Puno, Peru, to 7.8% in Matlab, Bangladesh). The odds of having ACO were higher with household exposure to biomass fuel smoke (odds ratio [OR], 1.48; 95% CI, 0.98-2.23), smoking tobacco (OR, 1.28 per 10 pack-years; 95% CI, 1.22-1.34), and having primary or less education (OR, 1.35; 95% CI, 1.07-1.70) as compared to nonobstructed nonasthma individuals. ACO was associated with severe obstruction (FEV1 %, <50; 31.6% of ACO vs 10.9% of COPD alone) and severe spirometric deficits compared with participants with asthma (-1.61 z scores FEV1; 95% CI, -1.48 to -1.75) or COPD alone (-0.94 z scores; 95% CI, -0.78 to -1.10). CONCLUSIONS: ACO may be as prevalent and more severe in LMICs than has been reported in high-income settings. Exposure to biomass fuel smoke may be an overlooked risk factor, and we favor diagnostic criteria for ACO that include environmental exposures common to LMICs. PMID- 30291843 TI - Loss of Sfrp2 contributes to the neurological disorders related with morphine withdrawal via Wnt/beta-catenin signaling. AB - Morphine administration is a medical problem characterized by compulsive opioid use that causes terrible negative consequences. The exact mechanisms of morphine induced dependence and morphine withdrawal symptoms remain unclear. Recent studies have revealed that the upregulation of Wnt/beta-catenin signaling plays important roles in morphine exposure and morphine withdrawal. Secreted frizzled related protein 2 (Sfrp2) can prevent the activation of Wnt/beta-catenin signaling by competing with the Frizzled receptor for Wnt ligands. We conducted this study aimed to evaluate the effect of iatrogenic trauma induced by stereotactic surgery and the protective effect of stereotaxic Sfrp2 injection on morphine withdrawal symptoms in Male Sprague Dawley (SD) rats. Many techniques including western blot analysis and immunoprecipitation were used. Anxiety related behaviors, morphine withdrawal syndrome, and dendritic spines were also examined in male SD rats after morphine treatment and stereotaxic injection of Sfrp2. Western blot results suggested that Wnt signaling was activated in the nucleus accumbens of SD rats suffering from morphine withdrawal and that Sfrp2 attenuated the overexpression of Wnt signaling. Similarly, the withdrawal-like symptoms of morphine dependent rats were abrogated by intracerebral Sfrp2 injection. The iatrogenic trauma induced by stereotactic surgery showed no influence on the Wnt signaling and withdrawal-like symptoms. Moreover, the results of Golgi-cox staining and DiI staining indicated that the damage on proximal spine density caused by morphine treatment was restored by intracerebral Sfrp2 injection. Together, the data presented here indicated that Sfrp2 abrogated the neurological disorders and loss of proximal spine related with morphine withdrawal via Wnt/beta-catenin signaling. PMID- 30291844 TI - Immunoinformatics and molecular docking studies reveal potential epitope-based peptide vaccine against DENV-NS3 protein. AB - Dengue, still a "Neglected Tropical Disease" is somehow injustice and remains uncontrolled globally. World Health Organization (2012-2020) reported that the world's half population is living in dengue-affected regions. Therefore, effective drug candidates or promising vaccines are urgently needed to control the dengue. It is an acute febrile disease caused by mosquito borne dengue viruses (DENVs) which belong to the genus Flavivirus with four serotypes. In present work, immunoinformatics approach was utilized to predict the antigenic epitopes of dengue proteins for the development of DENV vaccine. B-cell and cytotoxic T-lymphocyte epitopes were predicted for NS3 dengue protein. Docking complexes of 17 antigenic B-cell epitopes of various lengths and 4 CTL epitopes with antigenic sites were investigated followed by binding interaction analyses of top predicted peptides with MHC-I HLA-A2 molecule. These predicted epitopes with antigenic amino acids might present a preliminary set of peptides for future vaccine development against DENV. PMID- 30291845 TI - Conformational states of Zika virus non-structural protein 3 determined by molecular dynamics simulations with small-angle X-Ray scattering data. AB - Zika virus (ZIKV) has become a great public health emergency. Its non-structural protein 3 (NS3) is a key enzyme in viral replication and has been considered as a potential therapeutic target. A conformational characterization of ZIKV NS3 is critical for a comprehensive understanding of its molecular interactions and functions. However, the high conformational flexibility of solution NS3 obstacles the structural characterization of NS3 solely from the experimental observable that averages over its heterogeneous conformations. Here, we employed replica exchange with solute tempering (REST) method to simulate the di-domain protein ZIKV NS3. Three independent MD simulations identified a conserved conformational ensemble of NS3, consisting of a major conformational state and several minor states from compact to loose conformations. The major state agrees well with the scattering profile from small-angle X-ray scattering (SAXS) experiments. Moreover, the simulated ensemble is supported by a direct data-fitting result that requires both short- and long-range structural contacts to recover the experimental data. We discussed the interplay between simulation and experiment in ensemble construction of flexible biomolecules and shed light on the physically derived conformational ensembles. PMID- 30291846 TI - Overexpression of Desmoglein 2 in a mouse model of Gorlin syndrome enhances spontaneous basal cell carcinoma formation through STAT3-mediated Gli1 expression. AB - Activation of the Hedgehog (Hh) pathway is causative of virtually all sporadic and Gorlin syndrome-related basal cell carcinomas (BCC), with loss of function of Patched1 (Ptc1) being the most common genomic lesion. Sporadic BCCs also overexpress desmoglein-2 (Dsg2), a desmosomal cadherin normally found in the basal layer. Using a mouse model of Gorlin syndrome (Ptc1+/lacZ mice), we found that overexpressing Dsg2 in the basal layer (K14-Dsg2/Ptc1+/lacZ) or the superficial epidermis (Inv-Dsg2/Ptc1+/lacZ mice) resulted in increased spontaneous BCC formation at 3 and 6 months, respectively. The tumors did not show loss of heterozygosity of Ptc1, despite high levels of Gli1 and phosphorylated Stat3. A panel of sporadic human BCCs showed increased staining of both Dsg2 and P-Stat3 in 9/9 samples. Overexpression of Dsg2 in ASZ001 cells, a Ptc1-/- BCC cell line, induced Stat3 phosphorylation and further increased Gli1 levels, both in an autocrine and paracrine manner. Three different Stat3 inhibitors reduced viability and Gli1 expression in ASZ001 cells, but not in HaCaT cells. Conversely, stimulation of Stat3 in ASZ001 cells with IL-6 increased Gli1 expression. Our results indicate that Dsg2 enhances canonical Hh signaling downstream of Ptc1 to promote BCC development through the activation of P-Stat3 and regulation of Gli1 expression. PMID- 30291847 TI - Implementation of a reformulated Roche(r) bilirubin Gen.3 reagent did not affect the relationship between BiliChek transcutaneous and Roche total serum bilirubin. AB - OBJECTIVE: Determine whether introduction of a reformulated bilirubin reagent, the Roche bilirubin Gen.3 assay, changed the relationship between BiliChek transcutaneous bilirubin (TcB) and total serum bilirubin (TSB). DESIGN AND METHODS: TcB results from term infants in the level 1 nursery obtained within one hour of a TSB were reviewed over two periods, six months before and after the conversion from the previous generation Roche bilirubin reagent to the new Roche Gen.3 bilirubin assay. TcB measurements were performed using BiliChek transcutaneous devices (Respironics, Marietta GA). Distribution of TSB results, and TcB minus TSB bias, were compared before and after introduction of the reformulated Roche bilirubin Gen.3 assay. Median and interquartile range (IQR) TSB values and bias were calculated. A statistical difference between median TSB values and bias were assessed using Man-Whitney test. RESULTS: A total of 301 paired TcB and TSB results were obtained, 172 before and 129 after implementation of the reformulated Roche bilirubin Gen.3 reagent. Median (IQR) TSB was 7.8 (6.8 8.7)mg/dL (133.3 (116.3-148.8) MUmol/L) before and 7.6 (6.7-8.4)mg/dL (130 (114.6 143.6)MUmol/L) after implementation of the reformulated reagent (p = .1373). Median (IQR) bias between TcB and TSB was 2.9 (2.2-3.7) mg/dL (49.6 (37.6 63.3)MUmol/L) before the reformulated reagent was implemented; and did not change at 2.9 (2.1-3.9) mg/dL (49.6 (35.9-66.7)MUmol/L) after implementation (p = .8242). CONCLUSION: Implementation of the reformulated Roche bilirubin Gen.3 reagent did not affect the relationship between BiliChek transcutaneous and total serum bilirubin; thus no changes were needed to the neonatal TcB screening protocol as a result of the new bilirubin reagent. PMID- 30291848 TI - Traceability of immunosuppressant's mass concentration results obtained using different commercial calibrators. AB - BACKGROUND: Due to the high inter-variability in immunosuppressants pharmacokinetics, therapeutic drug monitoring of these drugs is essential in order to minimize the risk of rejection after organ transplantation. Thus, results facilitated to clinicians by clinical laboratories for these drugs should be as reliable as possible. The knowledge of metrological traceability and performing compatibility studies can allow ensuring reliability of these results, mainly, when laboratories introduce substantial changes in their measurement procedures, e.g., when they change the calibration materials. The aim of this study was to investigate, as an example, the traceability of the calibrator's assigned values from two manufacturers (Recipe and Chromsystems) and to perform compatibility studies for sirolimus and tacrolimus. MATERIAL AND METHODS: Traceability was described according to ISO 17511. Compatibility studies, based on the CLSI EP029-A guideline, were performed verifying the trueness processing the ERM(r)-DA111a and ERM(r)-DA110a reference materials. RESULTS: Traceability studies reveled that sirolimus and tacrolimus results were traceable to SI, except for sirolimus if Chromsystems' calibrators was used. Using Recipe's calibrators, the absolute relative biases and their expanded uncertainties were 1.23% and +/-6.10% for sirolimus, and 1.41% and +/-3.02% for tacrolimus. Furthermore, when Chromsystems' calibrators were used, these values were 12.2% and +/-6.02% for sirolimus, and 2.64% and +/-2.94% for tacrolimus. CONCLUSIONS: Results reported a lack of traceability and compatibility of sirolimus' results when Chromsystems' calibrators was used. In order to avoid it, laboratories should only use calibrators with assigned values traceable to highest reference materials or, alternatively, perform a compatibility study and apply a bias correction factor. PMID- 30291849 TI - Virtual chromoendoscopy using optical enhancement improves the detection of Barrett's esophagus-associated neoplasia. AB - BACKGROUND AND AIMS: The Seattle protocol for endoscopic Barrett's esophagus surveillance samples a small proportion of the mucosal surface area - risking a potentially high miss rate of early neoplastic lesions. We assess if the new iScan Optical Enhancement system (OE, Pentax) improves the detection of early BE associated neoplasia compared with high definition white light endoscopy (HD-WLE) in both expert and trainee endoscopists to target sampling of suspicious areas. Such a system may both improve early neoplasia detection and reduce the need for random biopsies. METHODS: 41 patients undergoing endoscopic BE surveillance from Jan 2016-Nov 2017 were recruited from 3 international referral centers. Matched still images in both HD-WLE (n=130) and iScan OE (n=132) were obtained from endoscopic examinations. Two experts, unblinded to the videos and histology, delineated known neoplasia, forming a consensus criterion standard. 7 expert and 7 trainee endoscopists marked one position per image where they would expect a target biopsy to identify dysplastic tissue. The same expert panel then reviewed magnification images and using a previously validated classification system attempted to classify mucosa as dysplastic or non-dysplastic based on the mucosal and vascular patterns observed on magnification endoscopy. Diagnostic accuracy, sensitivity, specificity, NPV, and PPV were calculated. Improvements in dysplasia detection in HD-WLE vs OE and interobserver agreement (IA) were assessed by multilevel logistic regression analysis and Krippendorff's alpha, respectively. Improvements in diagnostic performance were expressed as an odds ratio between the odds of an improvement in OE, compared with the odds of an improvement in WLE RESULTS: Accuracy of neoplasia detection was significantly higher in all trainees using OE versus WLE (76% vs 63%) and in 6 experts (84% vs 77%). OE improved sensitivity of dysplasia detection compared with WLE in 6 trainees (81% vs 71%) and 5 experts (77% vs 67%). Specificity improved in 6 trainees using OE vs WLE (70% vs 55%) and in 5 experts (92% vs 86%). PPV improved in both an expert and trainee cohort but NPV only improved significantly in trainees. Using the MV classification and OE magnification endoscopy compared with HD-WLE, we demonstrated improvements in accuracy (79.9% vs 66.7%), sensitivity (86.3% vs 83.4%) and specificity (71.2% vs 53.6%) of dysplasia detection. PPV improved (62% to 76.6%), as did NPV (67.7% to 78.5%).Interobserver agreement also improved using OE from 0.30 to 0.55. CONCLUSION: iScan OE may improve dysplasia detection on endoscopic imaging of BE, as well as the accuracy of histology prediction compared with HD-WLE, when using OE magnification endoscopy in conjunction with a simple classification system in both expert and non-expert endoscopists. PMID- 30291850 TI - Muscle damage and inflammation biomarkers after two ultra-endurance mountain races of different distances: 54 km vs 111 km. AB - The aims of this study were 1) to describe the effects of a 54 km and 111 km ultra-endurance mountain race on the biomarkers of muscle damage and inflammation, 2) to compare the effects between the two races regarding the biomarkers of muscle damage and inflammation. Sixteen ultra-endurance amateur runners volunteered to participate in this study. Ten runners completed a 54 km race (Group 1; age: 27.0 +/- 5.7; height: 179.5 +/- 5.8 cm; and body mass: 77.3 +/- 10.7 kg) and six completed a 111 km race (Group 2; age: 30.5 +/- 8.0; height: 179.4 +/- 5.5 cm; and body mass: 76.2 +/- 9.4 kg). Blood samples were taken at five different points during the investigation, 24 h before the race, immediately post-race, and again at 24, 48, and 72 h after the race. There were increases in leukocyte (Group 1: p <= .001, ES = 2.8; Group 2: p = .001, ES = 3.5) and platelet concentrations (Group 1: p <= .001, ES = 2.3; Group 2: p = .02, ES = 1.7) post-races. Significant inter-race differences were also observed in leukocyte at 72 h (Group 1: 5.5 +/- 0.9, Group 2: 4.2 +/- 0.9, p = .012, ES = 1.5). Erythrocytes, hematocrit and hemoglobin concentration decreased after 54 km and 111 km races at 24, 48 and 72 h (p <=.001, ES = 2.0-3.18). Serum uric acid concentration increased after the 54 km race (pre = 4.9 +/- 1.2 - post = 7.3 +/- 1.0 8 mg/dl; p <= .001, ES = 2.4), and also the 111 km race (pre = 5.3 +/- 0.9 - post = 6.7 +/- 0.8 mg/dl; p < .008, ES = 2.2). GPT, GOT and LDH had changed by the end of the races (p < .05) and differences between the groups were observed in GOT post-race (p = .008, ES = 1.7) 24 h (p = .004, ES = 1.8), 48 h (p = .007, ES = 1.6), and 72 h (p = .02, ES = 1.4) and also in LDH at 24, 48, 72 h. Serum creatinine decreased post-race in Group 1 (pre = 1.1 +/- 0.1 - post = 1.4 +/- 0.2 mg/dl; p = .001, ES = 1.5) and Group 2 (pre = 1.2 +/- 0.1, post = 1.5 +/- 0.2; p = .002, ES = 3.3) along with CK and myoglobin. In addition, values did not return to baseline levels after 72 h in Group 2 for C-reactive protein, myoglobin, and CK. Differences between the races were also observed post-race in Troponin I (Group 1 = 0.06 +/- 0.05, 111 km = 0.02 +/- 0.01 MUg/l, p = .047, ES = 1.1) and C reactive protein post-race (Group 2 = 2.5 +/- 1.6, 111 km = 18.2 +/- 6.4 mg/l, p <= .001, ES = 4.4) at 24 and 48 h. The athletes had increased concentrations of markers associated with damage, inflammation, muscle injury and cardiac damage after the races. Furthermore, athletes who completed the greater distance (111 km) had higher concentrations of the markers associated with muscle damage and muscle inflammation which remained changed for a period of 72 h. However, the participants of the 'shorter race' showed higher values associated with cardiac damage. Consequently, athletes who take part in these kinds of races should wait at least 72 h before training with high load. PMID- 30291851 TI - A Simple and Noninvasive DOSY NMR Method for Droplet Size Measurement of Intact Oil-In-Water Emulsion Drug Products. AB - In a typical oil-in-water emulsion drug product, oil droplets with varied sizes are dispersed in a water phase and stabilized by surfactant molecules. The size and polydispersity of oil droplets are critical quality attributes of the emulsion drug product that can potentially affect drug bioavailability. More critically, to ensure accuracy in characterization of the finished drug product, analytical methods should introduce minimal physical perturbation (e.g., temperature variation or dilution) before the analysis. The classical methods of dynamic light scattering or electron microscopy can be used but they generally require sample dilution or harsh preparation conditions, respectively. By contrast, the size distribution of emulsion formulations can be assessed with a simple and noninvasive solution nuclear magnetic resonance method, viz. two dimensional Diffusion Ordered SpectroscopY. The two-dimensional Diffusion Ordered SpectroscopY method probed signal decay of methyl resonances from oil and sorbate molecules and was applied to three types of U.S.-marketed emulsion drug products, that is, difluprednate, cyclosporine, and propofol, yielding measured droplet sizes of 40-280 nm in diameter. The high precision of +/-6 nm of the new nuclear magnetic resonance method allows analytical differentiation of lot-to-lot and brand-to-brand droplet size differences in emulsion drug products, critical for drug-quality development, control, and surveillance. PMID- 30291852 TI - The effects of exercise on cognition and gait in Parkinson's disease: A scoping review. AB - Cognitive and gait deficits are two debilitating symptoms that occur in Parkinson's disease (PD). Importantly, a relationship between cognitive and gait deficits exists in PD, suggesting reliance on cognition is increased to compensate for gait deficits and/or deterioration of cognition and gait may share common mechanisms. Rehabilitation strategies targeting one factor could lead to the improvement of the other, presenting a unique opportunity to treat both simultaneously. Gold-standard pharmaceuticals partially alleviate these deficits with significant side effects, highlighting the importance of investigating adjunct therapies like exercise. We critically reviewed the influence of three exercise modalities (aerobic, resistance, and goal-based) on cognition and/or gait in PD. Most studies showed improvements in cognition or gait, yet, a limited number investigated them concurrently. This is the first review examining exercise for cognition and gait in PD. Key gaps in the literature are identified; potential exercise-driven mechanisms for enhancements in cognition and gait proposed, and suggestions for the design of future studies investigating the effects of exercise on cognition and gait in PD. PMID- 30291853 TI - A Mesenchymal stem cell line (B10) increases angiogenesis in a rat MCAO model. AB - A human mesenchymal stem cell line (B10) transplantation has been shown to improve ischemia-induced neurological deficits in animal stroke models. To understand the underlying mechanism, we have investigated the effects of B10 transplantation on cerebral angiogenesis in a rat middle cerebral artery occlusion (MCAO) model. B10 cells were transplanted intravenously 24 h after MCAO. Immunofluorescence staining results showed that compared to PBS-groups, vWF positive vessel and endoglin positive new vessels were increased in B10 transplanted MCAO groups in the lesion areas. The mRNA of angiogenesis factors including placental growth factor and hypoxia inducible factor (HIF)-1alpha were increased 3 days after MCAO in the core and IBZ areas of B10-transplanted group. Angiopoetin1 mRNA was increased only in the IBZ. Western blotting results showed that HIF-1alpha and vascular endothelial growth factor (VEGF) proteins were increased in B10-transplanted group. Both HIF-1alpha and VEGF were expressed in macrophage/microglia in the core area. In the IBZ, however, HIF-1alpha was expressed both in astrocytes and macrophage/microglia, while VEGF was expressed only in macrophage/microglia. Moreover, TGFbeta protein levels were found to be increased in B10-transplanted group in the core and IBZ regions. Cell culture experiments using a human microglia cell line (HMO6) and B10 showed that IL-1beta induced VEGF mRNA expression in both cell types. IL-1beta was found to be highly expressed in B10 cells, and its co-culture with HMO6 further increased that in B10. Co-culture increased VEGF mRNA in both B10 and HMO6. In the rat brains, IL 1beta was expressed in macrophage/microglia and transplanted-B10 cells in the core. IL-1beta positive cell number was increased slightly, but significantly in B10-transplanted rats. To explore further, IL-1beta expression was silenced in B10 cells by transfecting mRNA specific siRNA, and then transplanted in MCAO rats. Immunostaining result showed that endoglin positive area was decreased in IL-1beta-silenced B10 transplanted groups compared to nonsilenced-B10 transplanted groups. Interestingly, vessel-like structure appeared as early as 3 days after MCAO in IL-1beta-silenced B10-transplanted group. Thus our results demonstrated that B10 cells increased angiogenesis in MCAO rat model, through the regulation of HIF-1alpha and VEGF expression, where IL-1beta might play a role. PMID- 30291854 TI - Matrices, scaffolds & carriers for cell delivery in nerve regeneration. AB - Nerve injuries can be life-long debilitating traumas that severely impact patients' quality of life. While many acellular neural scaffolds have been developed to aid the process of nerve regeneration, complete functional recovery is still very difficult to achieve, especially for long-gap peripheral nerve injury and most cases of spinal cord injury. Cell-based therapies have shown many promising results for improving nerve regeneration. With recent advances in neural tissue engineering, the integration of biomaterial scaffolds and cell transplantation are emerging as a more promising approach to enhance nerve regeneration. This review provides an overview of important considerations for designing cell-carrier biomaterial scaffolds. It also discusses current biomaterials used for scaffolds that provide permissive and instructive microenvironments for improved cell transplantation. PMID- 30291855 TI - Association of STAT4, TGFbeta1, SH2B3 and PTPN22 polymorphisms with autoimmune hepatitis. AB - : The physiopathology of autoimmune hepatitis (AIH) is complex and still not fully elucidated. The genes localized outside the histocompatibility complex involved in regulation and signal transduction of the immune system SH2B3, TGFbeta1, STAT4 and PTPN22 could be associated to the susceptibility and hepatocyte lysis mechanism of this lethal autoimmune disorder. PATIENTS AND METHODS: We investigated four polymorphic sites in SH2B3 (rs3184504), TGFbeta1 (rs1800471), STAT4 (rs7574865) and PTPN22 (rs2476601) in 45 AIH patients and 150 healthy controls from Tunisia using real-time PCR. RESULTS: Significant associations were found for SH2B3 T allele (OR = 1.861; p = 0.015, pc = 0.366) and PTPN22 A allele (OR = 7.070; p = 0.026; pc = 1.00) and AIH with opposite homozygous being protective against the disease (CC genotype with OR = 0.420, p = 0.025; GG genotype with OR = 0.136, p = 0.025, respectively). No statistically significant associations were found for the TGFbeta1 and STAT4 polymorphisms with AIH susceptibility. CONCLUSION: Our work enlarges information on non-HLA genes that are associated with AIH by focusing in a region of the world that was poorly molecularly characterized for this disease. PMID- 30291856 TI - State of the art in Stratum Corneum research: The biophysical properties of ceramides. AB - This review is summarizing an important part of the state of the art in stratum corneum research. A complete overview on discoveries about the general biophysical and physicochemical properties of the known ceramide species' is provided. The ceramides are one of the three major components of the lipid matrix and mainly govern its properties and structure. They are shown to exhibit very little redundancy, despite the minor differences in their chemical structure. The results are discussed, compared to each other as well as the current base of knowledge. New interesting aspects and concepts are concluded or suggested. A novel interpretation of the 3-dimensional structure of the lipid matrix and its influence on the barrier function will be discussed. The most important conclusion is the presentation of a new and up to date theoretical model of the nanostructure of the short periodicity phase. The model suggests three perpendicular layers: The rigid head group region, the rigid chain region and, a liquid-like overlapping middle layer. The general principle of the skin barrier function is highlighted in regard to this structure and the ceramides biophysical and physicochemical properties. As a result of these considerations, the entropy vs. enthalpy principle is introduced, shedding light on the function as well as the effectiveness of the skin barrier. Additionally, general ideas to effectively overcome this barrier principle for dermal and transdermal delivery of actives or how to use it for specific targeting of the stratum corneum are proposed. PMID- 30291857 TI - A simple SI-type model for HIV/AIDS with media and self-imposed psychological fear. AB - Infectious diseases can have a large impact on society, as they cause morbidity, mortality, unemployment, inequality and other adverse effects. Mathematical models are invaluable tools in understanding and describing disease dynamics with preventive measures for controlling the disease. The roles of media coverage and behavioral changes due to externally imposed factors on the disease dynamics are well studied. However, the effect of self-imposed psychological fear on the disease transmission has not been considered in extant research, and this gap is addressed in the present investigation. We propose a simple SI-type model for HIV/AIDS to assess the effects of media and self-imposed psychological fear on the disease dynamics. Local and global dynamics of the system are studied. Global sensitivity analysis is performed to identify the most influential parameters that have significant impact on the basic reproduction number. After calibrating our model using HIV case data-sets for Uganda and Tanzania, we calculate the basic reproduction numbers in the study period using the estimated parameters. Furthermore, a comparison of the effects of awareness and self-imposed psychological fear effects reveals that awareness is more effective in eliminating the burden of HIV infection. PMID- 30291858 TI - Metabolic responses of brown planthoppers to IR56 resistant rice cultivar containing multiple resistance genes. AB - The brown planthopper (Nilaparvata lugens Stal, BPH) is one of the most destructive pests in rice production, and rice resistance is thought to be an economical and environmentally friendly strategy against BPH. Although resistant rice cultivars have been widely applied to control BPH, little is known regarding the impact of the ingestion of resistant plant phloem on the BPH physiological metabolism. In this study, the differences in the metabolic responses of BPH nymphs during the first 72 h after ingesting susceptible TN1 and resistant IR56 plant phloem were compared. The results showed that BPH nymphs feeding on IR56 plants exhibited significant decreases in honeydew excretion and body weight, and significantly lower concentrations of most of the detected sugars, vitamins and some essential amino acids but higher levels of most amides, free fatty acids and some non-essential amino acids. These findings indicate that the energy metabolism and nutrition supply of these nymphs were disturbed by the resistant rice plants. The qPCR results revealed that BPH could actively adapt to IR56 plants by upregulating the gene expression levels of some detoxification enzymes, including GST, CarE and POD, to some extent. These results provide additional information to improve our understanding of physiological mechanism underlying the loss of BPH fitness caused by resistant rice varieties. PMID- 30291859 TI - A new interpretation of the mechanism underlying visual anomalies of astronauts. PMID- 30291860 TI - Early monocular enucleation selectively disrupts neural development of face perception in the occipital face area. AB - : Retinoblastoma generally occurs before 5 years of age and often requires enucleation (surgical removal of one eye) of the cancerous eye. We have previously shown using behavioural methods that this disruption in binocular vision during the critical period of visual development results in impaired face perception. In this case series study, we sought to determine the underlying neural correlates of this face perception deficit by examining brain activity in regions of cortex that preferentially respond to visual images of faces and places in 6 adults who had one eye enucleated early in life due to retinoblastoma. A group of 10 binocularly-intact adult controls were recruited for comparison. Functional magnetic resonance imaging (fMRI) was conducted over two separate runs for each participant in one scanning session. Each run consisted of 6 blocks each of face, place, and object images. Region-of-interest analyses were conducted to locate face-preferential [fusiform face area (FFA), occipital face area (OFA)] and place-preferential [parahippocampal place area (PPA), transverse occipital sulcus (TOS)] regions-of-interest. Descriptive statistics are reported. RESULTS: Enucleated adults exhibited reduced functional activation in face-preferential regions (left FFA, right OFA, left OFA), but similar activation within the face-preferential right FFA and the place preferential regions (bilateral PPA and TOS). CONCLUSIONS: These results indicate that early monocular enucleation prevents robust development of late-maturing face processing capabilities and that this disruption is specific to face networks and not to networks supporting other visual image categories. PMID- 30291861 TI - A quantitative analysis of the performance of computing architectures used in neural simulations. AB - BACKGROUND: Numerical solutions of neuron models are helping neuroscientists gain new insights into the behavior of neural systems. Although computing power is increasing, the complexity of the systems being simulated is also increasing. If the computation is not well matched to the computing hardware, simulations can take lengthy times to run, which can make it more difficult to draw inferences from those simulations and also to use them in feedback with living neurons such as in the dynamic clamp. NEW METHOD: In this paper, we perform a quantitative analysis to get a better sense of how much impact the hardware architectures can have on simulation performance. Three different architectures are implemented on the same hardware platform and compared with respect to simulation time, error, and resources used. RESULTS: The results indicate that a lookup table approach to evaluate functions can decrease simulation time by orders of magnitude with respect to the traditional approach of mathematical operations. COMPARISON WITH EXISTING METHOD(S): There are many different ways to implement a lookup table approach to evaluate a function. The method presented in this paper sacrifices some speed for greater generality and accuracy with respect to other published methods. CONCLUSIONS: Lookup tables with 32 interpolation points can dramatically speed up computation time of neural simulations without adding significant error. In this paper linear interpolation was used, but higher order interpolation could be used to further reduce simulation time. PMID- 30291862 TI - Regulation of obesity-associated metabolic disturbance by the antipsychotic drug olanzapine: Role of the autophagy-lysosome pathway. AB - Metabolic disturbance is commonly observed in schizophrenia patients, and the metabolic impacts of atypical antipsychotics such as olanzapine (OLA) have received much attention. Drug naive schizophrenia patients display metabolic abnormality to varying degrees, but how this shapes the metabolic responses to chronic OLA exposure is unknown. Using high-fat diet (HFD, 8 weeks) induced obesity, here we explored the metabolic outcome of chronic OLA exposure in conditions of pre-existing metabolic disturbance. OLA treatment (2 mg/kg) for 4 weeks led to markedly reduced body weight and adiposity in obese mice, concomitant with reduced adipose inflammation and hepatic steatosis. No significant change was observed on insulin sensitivity or energy expenditure after OLA exposure. Mechanistically, OLA restored autophagic clearance in the subcutaneous adipose tissue of obese mice, in line with its potentiation of lysosomal function in adipocytes. The metabolic phenotypes induced by OLA were partially reversed by chemical suppression of autolysosome. Together, these data uncover distinct metabolic effects of OLA in obesity involving the regulation of adipose tissue autophagy, and suggest a complicated link between OLA therapy and metabolic disturbance in schizophrenia. PMID- 30291863 TI - Tissue-specific gene regulation corresponds with seasonal plasticity in female testosterone. AB - Testosterone (T) is a sex steroid hormone that often varies seasonally and mediates trade-offs between territorial aggression and parental care. Prior work has provided key insights into the 'top-down' hypothalamic control of this seasonal plasticity in T, yet mechanisms acting outside of the brain may also influence circulating T levels. We hypothesized that peripheral mechanisms may be especially critical for females, because peripheral regulation may mitigate the costs of systemically elevated T. Here, we begin to test this hypothesis using a seasonal comparative approach, measuring gene expression in peripheral tissues in tree swallows (Tachycineta bicolor), a songbird with intense female-female competition and T-mediated aggression. We focused on the gonad and liver for their role in T production and metabolism, respectively, and we contrasted females captured during territory establishment versus incubation. During territory establishment, when T levels are highest, we found elevated gene expression of the hepatic steroid metabolizing enzyme CYP2C19 along with several ovarian steroidogenic enzymes, including the androgenic 5alpha-reductase. Despite these seasonal changes in gene expression along the steroidogenic pathway, we did not observe seasonal changes in sensitivity to upstream signals, measured as ovarian mRNA abundance of luteinizing hormone receptor. Together, these data suggest that differential regulation of steroidogenic gene expression in the ovary is a potentially major contributor to seasonal changes in T levels in females. Furthermore, these data provide a unique and organismal glimpse into tissue-specific gene regulation and its potential role in hormonal plasticity in females. PMID- 30291864 TI - Using a keratinase to degrade chicken feathers for improved extraction of glucocorticoids. AB - Stress in animals is a concern in conservation breeding programs and livestock production facilities. The biological stress response is mediated by the release of glucocorticoids, which can suppress reproduction, growth, and immunity if recurrently activated. Feathers can be used to extract and monitor concentrations of corticosterone, a primary glucocorticoid in birds. However, current techniques for extracting feather corticosterone present challenges, including difficulty assessing extraction efficiency or hormone recovery, inconsistent extraction across feather lengths or pieces, and several uncertainties regarding the mechanisms of hormone deposition into feathers. To overcome such challenges and to provide tools useful for facilitating conservation breeding and livestock production, we developed and validated an alternative procedure for extracting feather glucocorticoids. We first developed a protocol to enzymatically digest the protein matrix of feathers using a keratinase, such that non-protein analytes could be isolated by organic extraction. We then developed an extraction protocol and evaluated techniques by measuring extraction efficiency and by testing parallelism and hormone recovery (accuracy) using radioimmunoassay. Our results demonstrated high and consistent extraction efficiency, as well as high accuracy and reliable parallelism to a standard curve upon measurement of corticosterone concentrations from extracts. By dissolving feather material into solution prior to extraction, we were able to replicate hormone deposition into the feather matrix and ensure consistent extraction across feathers. This work provides additional support for the validity and practicality of extracting glucocorticoids from feathers. Our extraction protocol is likely to extend to other applications as well, including the isolation of numerous non-protein analytes from various keratinized tissues. PMID- 30291865 TI - Performance of Bt-susceptible and -heterozygous genotypes of Spodoptera frugiperda (J.E. Smith) possessing single- or dual-gene resistance alleles in sequential feedings of non-Bt and Cry1A.105/Cry2Ab2 maize leaf tissues. AB - We simulated larval feeding behavior in seed blends of non-Bt and Bt maize to determine if seed blends create more favorable conditions for heterozygous resistant insects over their Bt-susceptible counterparts. Survival, growth, development, and progeny production of four genotypes of the fall armyworm, Spodoptera frugiperda, Bt-susceptible (aabb), Cry1A.105 heterozygous resistant (Aabb), Cry2Ab2 heterozygous resistant (aaBb), and Cry1A.105/Cry2Ab2 heterozygous resistant (AaBb), were evaluated in eight feeding sequences (Seq 1-8) of non-Bt and MON89034 Bt maize leaf tissue expressing the Cry1A.105 and Cry2Ab2 proteins. We report variation in the performance of the four genotypes across the feeding sequences and biological parameters measured. Three heterozygous genotypes generally outperformed the susceptible genotype in larval survival, pupation rate, pupal weight, and progeny production. The performance was greater for Aabb over aaBb, AaBb over Aabb or aaBb, in two of the feeding sequences. The findings of this study could have important implications in assessing the risk of seed blends as refuge plantings for Bt crop resistance management where resistance in the target pest is not functionally recessive. PMID- 30291866 TI - Perkinsus olseni in the short neck yellow clam, Paphia malabarica (Chemnitz, 1782) from the southwest coast of India. AB - Parasites of the genus Perkinsus predominantly infect bivalves, and two species among them, P. olseni and P. marinus, are notifiable to OIE. P. olseni infections are known to cause extensive damage to wild as well as farmed bivalves globally with enormous implications to its fishery. Consequent to the initiation of a surveillance programme for aquatic animal diseases in India, Perkinsus infections were observed in many species of bivalves. The present paper describes P. olseni infections in the short neck yellow clam, Paphia malabarica from the southwest coast of India. Diagnosis of the parasite was carried out using Ray's Fluid Thioglycollate Medium culture, histology, in-situ hybridisation and molecular taxonomy. Pathology of infection and development of zoospores is also described. This forms the first report of a P. olseni infection in P. malabarica. High prevalence and intensity of infection of Perkinsus in clams raises concerns, as clam reserves in this geographical area sustain fisheries and the livelihoods of local fishing communities. PMID- 30291867 TI - NEAT1 contributes to the CSC-like traits of A549/CDDP cells via activating Wnt signaling pathway. AB - Long non-coding RNAs (lncRNAs) have been identified to exert crucial roles in tumorigenesis and can serve as novel biomarkers for cancer therapy including lung cancer. Cisplatin is a first-line chemotherapeutic agent in non-small cell lung cancer (NSCLC), but the therapeutic effect is unsatisfactory, partly due to drug resistance. Emerging evidence showed that chemo-resistance is associated with acquisition of cancer stem cell (CSC)-like properties. Cisplatin resistance remains a major obstacle in the treatment of lung cancer, and its mechanism is still not fully elucidated. Meanwhile, CSCs have been involved in tumor metastasis, tumor recurrence and chemotherapy resistance. So far, the mechanism of nuclear enriched abundant transcript 1 (NEAT1) in modulating CSCs in lung cancer remains barely known. Therefore, we aimed to explore the correlation between NEAT1 and cancer stem cells in lung cancer. In our current study, we observed that CSC-like traits were much more enriched in cisplatin-resistant A549/CDDP cells. In addition, NEAT1 was obviously up-regulated in A549/CDDP cells compared with parental A549 cells. Knockdown of NEAT1 decreased the CSC-like properties of A549/CDDP cells through inhibiting tumor cell sphere volume, repressing CSC-like biomarkers levels and restraining CD44 positive cell ratios. Oppositely, overexpression of NEAT1 enhanced the stemness respectively. Moreover, it has been reported that Wnt pathway is implicated in many vital cellular functions including cancer stem cells. Here, it was exhibited that Wnt signal pathway was inactivated by knockdown of NEAT1 whereas activated by NEAT1 overexpression in A549/CDDP cells. Taken these together, it was indicated that NEAT1 could exert a novel biological role in NSCLC chemo-resistance. PMID- 30291868 TI - Longitudinal correlations between MRE, MRI-PDFF, and liver histology in patients with non-alcoholic steatohepatitis: Analysis of data from a phase II trial of selonsertib. AB - BACKGROUND & AIMS: Non-invasive tools for monitoring treatment response and disease progression in non-alcoholic steatohepatitis (NASH) are needed. Our objective was to evaluate the utility of magnetic resonance (MR)-based hepatic imaging measures for the assessment of liver histology in patients with NASH. METHODS: We analyzed data from patients with NASH and stage 2 or 3 fibrosis enrolled in a phase II study of selonsertib. Pre- and post-treatment assessments included centrally read MR elastography (MRE)-estimated liver stiffness, MR imaging-estimated proton density fat fraction (MRI-PDFF), and liver biopsies evaluated according to the NASH Clinical Research Network classification and the non-alcoholic fatty liver disease activity score (NAS). RESULTS: Among 54 patients with MRE and biopsies at baseline and week 24, 18 (33%) had fibrosis improvement (>=1-stage reduction) after undergoing 24 weeks of treatment with the study drug. The area under the receiver operating characteristic curve (AUROC) of MRE-stiffness to predict fibrosis improvement was 0.62 (95% CI 0.46-0.78) and the optimal threshold was a >=0% relative reduction. At this threshold, MRE had 67% sensitivity, 64% specificity, 48% positive predictive value, 79% negative predictive value. Among 65 patients with MRI-PDFF and biopsies at baseline and week 24, a >=1-grade reduction in steatosis was observed in 18 (28%). The AUROC of MRI-PDFF to predict steatosis response was 0.70 (95% CI 0.57-0.83) and the optimal threshold was a >=0% relative reduction. At this threshold, MRI-PDFF had 89% sensitivity and 47% specificity, 39% positive predictive value, and 92% negative predictive value. CONCLUSIONS: These preliminary data support the further evaluation of MRE-stiffness and MRI-PDFF for the longitudinal assessment of histologic response in patients with NASH. LAY SUMMARY: Liver biopsy is a potentially painful and risky method to assess damage to the liver due to non alcoholic steatohepatitis (NASH). We analyzed data from a clinical trial to determine if 2 methods of magnetic resonance imaging - 1 to measure liver fat and 1 to measure liver fibrosis (scarring) - could potentially replace liver biopsy in evaluating NASH-related liver injury. Both imaging methods were correlated with biopsy in showing the effects of NASH on the liver. PMID- 30291869 TI - Amphiregulin potentiates airway inflammation and mucus hypersecretion induced by urban particulate matter via the EGFR-PI3Kalpha-AKT/ERK pathway. AB - Ambient particulate matter (PM) promotes the development and exacerbation of chronic respiratory diseases, including chronic obstructive pulmonary disease (COPD) and asthma, by increasing inflammation and mucus hypersecretion. However, the biological mechanisms underlying PM-induced airway inflammation and mucus hypersecretion remain unclear. Amphiregulin (AREG) is an important ligand for epidermal growth factor receptor (EGFR) and participates in the regulation of several biological functions. Here, the PM-exposed human bronchial epithelial cell (HBEC) model was used to define the role of AREG in PM-induced inflammation and mucus hypersecretion and its related signaling pathways. The expression of AREG was significantly increased in a dose-dependent manner in HBECs subjected to PM exposure. Moreover, PM could induce inflammation and mucus hypersecretion by upregulating the expression of IL-1alpha, IL-1beta, and Muc-5ac in HBECs. The EGFR, AKT, and ERK signaling pathways were also activated in a time- and dose dependent manner. The AREG siRNA markedly attenuated PM-induced inflammation and mucus hypersecretion, and activation of the EGFR-AKT/ERK pathway. Exogenous AREG significantly increased the expression of IL-1alpha, IL-1beta, and Muc-5ac, and induced activation of the EGFR-AKT/ERK pathway in HBECs. Further, under PM exposure, exogenous AREG significantly potentiated PM-induced inflammation and mucus hypersecretion, and activation of the EGFR-AKT/ERK pathway. Tumor-necrosis factor-alpha converting enzyme (TACE) and EGFR specific inhibitor pretreatment showed that AREG was secreted by TACE-mediated cleavage to regulate PM-induced inflammation and mucus hypersecretion by binding to the EGFR. Moreover, according to the inhibitory effect of specific inhibitors of the class I PI3K isoforms, AKT and ERK, PM-induced inflammation and mucus hypersecretion was regulated by PI3Kalpha activation and its downstream AKT and ERK pathways. This study strongly suggests the adverse effect of AREG in PM-induced inflammation and mucus hypersecretion via the EGFR-PI3Kalpha-AKT/ERK pathway. These findings contribute to a better understanding of the biological mechanisms underlying exacerbation of chronic respiratory diseases induced by PM exposure. PMID- 30291870 TI - Prevalence of latent tuberculosis infection in transplant candidates: A systematic review and meta-analysis. AB - INTRODUCTION: Tuberculosis (TB) is considered as a serious complication for organ transplant recipients; therefore, the detection and appropriate treatment of latent infection are recommended for preventing active TB infections in the future. The objective of this review is to conduct a systematic review and meta analysis of studies assessing the prevalence of latent TB infection (LTBI) in transplant candidates. METHODS: Electronic databases, including MEDLINE (via PubMed), SCOPUS were searched until 30 June 2017. The prevalence of LTBI was estimated using the random effects meta-analysis. Heterogeneity was evaluated by subgroup analysis. Data were analyzed by STATA version 14. RESULTS: The pooled prevalence of LTBI based on tuberculin skin test (TST) in different transplant types was as follows: liver 24% (14%-33%, 95% CI), lung 22% (18%-26%), renal 21% (16%-27%, 95% CI) and hematopoietic stem cell transplantation (HCT) 14% (9%-19%). The prevalence of LTBI based on Interferon Gamma Release Assay (IGRA) tests in renal transplant candidates was 31% (95% CI; 25-37%), which was much higher than the prevalence of LTBI in liver transplant candidates (25%, 95% CI; 17-33%) and HCT transplant candidates (13%, 95% CI; 10-16%) and there was statistically significant differences between them. The pooled prevalence of indeterminate results based on IGRAs test in different transplant types was as follows: renal 6% (4%-8%, 95% CI) and liver 12% (2%-21%, 95% CI). Subgroup analysis revealed that there were statistically significant differences between the overall prevalence of indeterminate results by using IGRA tests in liver transplant candidates (12%, 95% CI; 2-21%) and renal transplant candidates (6%, 95% CI; 4 8%). The pooled prevalence of post-transplant TB was 2% (1%-2%, 95% CI) and its occurrence was more common in renal recipients (4% (2%-7%, 95% CI)) than in the liver transplant patients (1% (0%-2%, 95% CI)). The prevalence of LTBI in the subgroup (i.e. the patients' mean age was <50 years) was significantly higher than the prevalence of LTBI by using TST/IGRAs in the other subgroup (i.e. the patients' mean age was >=50 years). CONCLUSION: Our study suggests fair overall agreement between IGRAs and TST in patients requiring liver and HCT transplantation, while a superiority of IGRAs over TST in patients requiring renal transplantation was seen. PMID- 30291871 TI - Mutations in the HFE gene can be associated with increased lung disease severity in cystic fibrosis. AB - BACKGROUND AND OBJECTIVE: Genetic modifiers contribute to variable disease phenotype in cystic fibrosis (CF). We explored the association between mutations in the hemochromatosis (HFE) gene and disease severity in adults with CF. METHODS: HFE genotyping was performed in 163 adults with CF attending a single centre. Results were correlated with lung disease severity, prevalence of CF related diabetes (CFRD) and history of meconium ileus (MI) or distal intestinal obstruction syndrome (DIOS). RESULTS: Subjects with the C282Y substitution in the HFE protein (C282Y mutation) had a lower FEV1 percentage predicted (54% versus 66%, p = 0.029) and accelerated rate of FEV1 decline (-110 mL versus -80 mL per year respectively, p < 0.001) compared to subjects with a normal HFE genotype. C282Y substitutions were associated with increased rates of CFRD (58% versus 33%, p = 0.026) and a trend towards increased MI or DIOS (38% versus 19%, p = 0.05). H63D HFE substitutions were associated with a more rapid rate of decline in forced vital capacity (p = 0.01) and increased risk of MI or DIOS (p = 0.02). CONCLUSIONS: In subjects with CF, the C282Y HFE substitution was associated with worse lung function, and increased rates of CFRD and gastrointestinal complications. The H63D HFE substitution also impacted on disease phenotype, but to a lesser extent. The results support a role for HFE gene mutations as modifiers of CF phenotype. PMID- 30291872 TI - Identification of several key genes by microarray data analysis of bovine mammary gland epithelial cells challenged with Escherichia coli and Staphylococcus aureus. AB - PURPOSE: This study was aimed at exploring the mechanisms and identifying the key candidate genes associated with S. aureus and E. coli mastitis. METHODS: A public microarray dataset GSE24560 was downloaded. Differentially expressed genes (DEGs) were screened in E. coli- and S. aureus-infected primary bovine mammary gland epithelial cell (pBMEC) samples, and compared with control samples at 1 h, 6 h, and 24 h. A functional enrichment analysis was performed, and construction of a gene co-expression network was performed based on genes that showed consistent changes over time, which were identified using time series expression analysis. Then, a miRNA/TF regulatory network was constructed based on the genes in the co expression network. The genes in the miRNA/TF regulatory network were screened for involvement in related diseases. Furthermore, the expression of several selected DEGs was further validated using real-time RT-PCR. RESULTS: In total, 92 and 81 DEGs showed continuous differential expression over time in the E. coli- and S. aureus-inoculated groups. DEGs in the E. coli-inoculated group were associated with the RIG-I-like receptor signaling pathway, and those in the S. aureus-inoculated group were associated with the lysosome pathway. Time series expression analysis identified two gene clusters. NFKBIZ and GRO1 in the gene co expression network were associated with inflammatory and defense responses. Moreover, several genes such as CXADR, APP, and CXCL2 in the miRNA/TF regulatory network, were associated with infection, inflammation, or stress-related diseases. CONCLUSION: RIG-I like receptor pathway and several DEGs such as NFKBIZ, GRO1, CXCL2, and CXADR may play critical roles in the response to infection in pBMECs. PMID- 30291873 TI - Neuronal and astrocytic primary cilia in the mature brain. AB - Primary cilia are tiny microtubule-based signaling devices that regulate a variety of physiological functions, including metabolism and cell division. Defects in primary cilia lead to a myriad of diseases in humans such as obesity and cancers. In the mature brain, both neurons and astrocytes contain a single primary cilium. Although neuronal primary cilia are not directly involved in synaptic communication, their pathophysiological impacts on obesity and mental disorders are well recognized. In contrast, research on astrocytic primary cilia lags far behind. Currently, little is known about their functions and molecular pathways in the mature brain. Unlike neurons, postnatal astrocytes retain the capacity of cell division and can become reactive and proliferate in response to various brain insults such as epilepsy, ischemia, traumatic brain injury, and neurodegenerative beta-amyloid plaques. Since primary cilia derive from the mother centrioles, astrocyte proliferation must occur in coordination with the dismantling and ciliogenesis of astrocyte cilia. In this regard, the functions, signal pathways, and structural dynamics of neuronal and astrocytic primary cilia are fundamentally different. Here we discuss and compare the current understanding of neuronal and astrocytic primary cilia. PMID- 30291874 TI - LVQ-KNN: Composition-based DNA/RNA binning of short nucleotide sequences utilizing a prototype-based k-nearest neighbor approach. AB - Unbiased sequencing is an upcoming method to gain information of the microbiome in a sample and for the detection of unrecognized pathogens. There are many software tools for a taxonomic classification of such metagenomics datasets available. Numerous of them have a satisfactory sensitivity and specificity for known organisms, but they fail if the sample contains unknown organisms, which cannot be detected by similarity-based classification employing available databases. However, recognition of unknowns is especially important for the detection of newly emerging pathogens, which are often RNA viruses. Here we present the composition-based analysis tool LVQ-KNN for binning unclassified nucleotide sequence reads into their provenance classes DNA or RNA. With a 5-fold cross-validation, LVQ-KNN reached correct classification rates (CCR) of up to 99.9% for the classification into DNA/RNA. Real datasets gained CCRs of up to 94.5%. Comparing the method to another composition-based analysis tool, similar or better classification results were reached. LVQ-KNN is a new tool for DNA/RNA classification of sequence reads from unbiased sequencing approaches that could be applicable for the detection of yet unknown RNA viruses in metagenomic samples. The source-code, training and test data for LVQ-KNN is available at Github (https://github.com/ab1989/LVQ-KNN). PMID- 30291875 TI - One-step multiplex real-time RT-PCR for detection and typing of dengue virus. AB - Previous studies reported that severity of dengue is associated with multiple factors, including secondary infection, age, viral load and infecting serotype and genotype. In addition, other studies have reported that a dengue virus-2 (DENV-2) infection is associated with a prognosis of more severe clinical manifestations than DENV-1 and DENV-4 infections. For these reasons, the ability to identify the DENV serotypes is critical for optimal patient diagnosis and epidemiological studies. In this study, we developed a TaqMan probe-based, one step real-time reverse transcriptase-polymerase chain reaction (RT-PCR) system for detection and serotyping DENV. Our linear dynamic range (101 to 107 copies/reaction) showed the R2 values of DENV-1, 2, 3 and 4 as 0.998, 0.998, 0.994, and 0.998, respectively. The detection limits of DENV-1, 2, 3, and 4, were 10 copies/reaction, 100 copies/reaction, 10 copies/reaction, and 100 copies/reaction, respectively. Specificity test results indicated that this system is specific for DENV-1, 2, 3, and 4 and does not react with other viruses. Finally, we validated our results with five different real-time PCR instruments. Our results showed that the Ct values of the four serotype templates were similar in five real-time PCR instruments. Thus, this system provides an accurate method for detection and serotyping of DENV, which can be applied in diagnostics, surveillance, and epidemiology. Dengue can be found in many nations with varying socioeconomic and monetary resources. The results of our validation analyses using five different real-time PCR instruments suggest that this method can easily and confidently be used world-wide. PMID- 30291876 TI - Temporal dynamics of audiovisual affective processing. AB - This study used event-related potentials (ERPs) to investigate the time course of auditory, visual, and audiovisual affective processing. Stimuli consisted of naturalistic silent videos, instrumental music clips, or combination of the two, with valence varied at three levels for each modality and arousal matched across valence conditions. Affective ratings of the unimodal and multimodal stimuli showed evidence of visual dominance, congruency, and negativity dominance effects. ERP results for unimodal presentations revealed valence effects in early components for both modalities, but only for the visual condition in a late positive potential. The ERP results for multimodal presentations showed effects for both visual valence and auditory valence in three components, early N200, P300 and LPP. A modeling analysis of the N200 component suggested its role in the visual dominance effect, which was further supported by a correlation between behavioral visual dominance scores and the early ERP components. Significant congruency comparisons were also found for N200 amplitudes, suggesting that congruency effects may occur early. Consistent differences between negative and positive valence were found for both visual and auditory modalities in the P300 at anterior electrode clusters, suggesting a potential source for the negativity dominance effect observed behaviorally. The separation between negative and positive valence also occurred at LPP for the visual modality. Significant auditory valence modulation was found for the LPP, implying an integration effect in which valence sensitivity of the LPP emerged for the audiovisual condition. These results provide a basis for mapping out the temporal dynamics of audiovisual affective processing. PMID- 30291877 TI - Bioavailability of protein therapeutics in rats following inhalation exposure: Relevance to occupational exposure limit calculations. AB - Protein therapeutics represent a rapidly growing proportion of new medicines being developed by the pharmaceutical industry. As with any new drug, an Occupational Exposure Limit (OEL) should be developed to ensure worker safety. Part of the OEL determination addresses bioavailability (BA) after inhalation, which is poorly understood for protein therapeutics. To explore this, male Sprague-Dawley rats were exposed intravenously or by nose-only inhalation to one of five test proteins of varying molecular size (10-150 kDa), including a polyethylene glycol-conjugated protein. Blood, lung tissue and bronchoalveolar lavage (BAL) fluid were collected over various time-points depending on the expected test protein clearance (8 minutes-56 days), and analyzed to determine the pharmacokinetic profiles. Since the BAL half-life of the test proteins was observed to be > 4.5 h after an inhalation exposure, accumulation and direct lung effects should be considered in the hazard assessment for protein therapeutics with lung-specific targets. The key finding was the low systemic bioavailability after inhalation exposure for all test proteins (~<=1%) which did not appear molecular weight-dependent. Given that this study examined the inhalation of typical protein therapeutics in a manner mimicking worker exposure, a default 1% BA assumption is reasonable to utilize when calculating OELs for protein therapeutics. PMID- 30291878 TI - The regulatory challenge of chemicals in the environment: Toxicity testing, risk assessment, and decision-making models. AB - Environmental assessment for chemicals relies on models of fate, exposure, toxicity, risk, and impacts. Together, these models should provide scientific support for regulatory risk management decision-making, assuming that progress through the data-information-knowledge-wisdom (DIKW) hierarchy is both appropriate and sufficient. Improving existing regulatory processes necessitates continuing enhancement of interpretation and evaluation of key data for use in decision-making schemes, including ecotoxicity testing data, physical-chemical properties, and environmental fate processes. Yet, as environmental objectives also increase in scope and sophistication to encompass a safe chemical economy, testing, risk assessment, and decision-making are subject to additional complexity due to the ongoing interaction between science and policy models. Problems associated with existing design and implementation choices in science and policy have both limited needed development beyond chemo-centric environmental risk assessment modeling and constrained needed improvements in environmental decision-making. Without a thorough understanding of either the scientific foundations or the disparate evaluation processes for validation, quality, and relevance, this results in complex technical and philosophical problems that increase costs and decrease productivity. Both over- and under management of chemicals are consequences of failure to validate key model assumptions, unjustified standardized views on data selection, and inordinate reification (i.e., abstract concepts are wrongly treated as facts). PMID- 30291879 TI - The expression of adenosine receptors changes throughout light induced retinal degeneration in the rat. AB - The modulation of adenosine receptors, A1 (A1R) and A2A (A2AR), is neuroprotective in different models of retinal injury. In order to understand the processes underlying retinal degeneration, we studied the expression of adenosine receptors in the retinas of control and continuously illuminated (CI) rats by qRT PCR, Western blot (WB) and immunohistochemistry (IHC). Significant increases of A1R, A2AR, and A2BR mRNAs at 1, 5, and 7 days of CI (P < 0.0001) were observed by qRT-PCR. Also, a significant increase of A3R mRNA was detected after 5 and 7 days of CI. WB studies showed a significant rise of A1R on day 1 of CI and on days 5 and 7 (P < 0.0001), while A2AR increase was seen from 2 days of CI on (P < 0.001). After 1 day of CI, A1R immunoreactivity (A1R-IR) increased in ganglion cell layer, inner nuclear layer, and in both the outer and inner plexiform layers. After 2 days of CI, the A1R-IR went back to control levels. After 5 days of CI, a second rise in A1R, which persisted until 7 days of CI, was measured (P < 0.0001). A significant rise of A2aR immunoreactivity was also observed at day 2 of CI at GCL and INL and subsided at days 5 and 7 (P < 0.0001). The observed up regulation of A1R after 1 day of CI, corresponds with the peak of oxidative stress; while the rise of A2aR at day 2 of CI, coincides with the massive apoptosis of photoreceptors. We postulate that an early modulation of adenosine receptors could delay or prevent the degeneration of photoreceptors. PMID- 30291881 TI - Antibacterial activity of lysozyme-binding proteins from chicken egg white. AB - The purpose of this study was to establish a method for determining the bacteriolytic activity after separation of lysozyme-binding proteins from egg white. Lysozyme-binding proteins such as ovotransferrin and ovalbumin were separated by non-denaturing two-dimensional electrophoresis (2DE) and transferred to a membrane. The lysozyme activity of the separated and immobilized egg white proteins was assessed directly to produce a non-denaturing 3D map of the egg white proteins by incorporating an axis that combined each spot's lysozyme activity with the non-denaturing 2DE pattern. Lysozyme-ovotransferrin and lysozyme-ovalbumin complexes could be reconstructed in vitro after the cathode end fraction containing lysozyme was added to purified ovotransferrin and ovalbumin, respectively. These complexes retained lysozyme activity even after separation by non-denaturing 2DE. Furthermore, when the lysozyme-ovotransferrin complex from egg white was extracted after separation by isoelectric focusing by replacing the cathodic sodium hydroxide solution with phosphoric acid solution, the complex possessed bacteriolytic activity against both Bacillus subtilis and Escherichia coli. These methods can be applied to investigate protein complexes possessing bacteriolytic activity against a wide range of both Gram-positive and Gram-negative bacteria. PMID- 30291880 TI - MicroRNA-21 attenuates oxygen and glucose deprivation induced apoptotic death in human neural stem cells with inhibition of JNK and p38 MAPK signaling. AB - Neural stem cells (NSCs) persist in the mammalian brain throughout life and protect against hypoxia-ischemia injury. NSCs are being increasingly recognized as a novel therapeutic target for various neurological disorders. Previous research indicates that miR-21 attenuates hypoxia-ischemia induced apoptotic death in various cell types. However, whether miR-21 plays a role in this protective effect mediated by NSCs is unknown, particularly in human NSCs (hNSCs). The present study investigated whether miR-21 could prevent hNSC injury induced by oxygen and glucose deprivation (OGD). Upon challenge with OGD treatment, loss of cell viability was observed in cultured hNSCs, as shown by CCK 8 assay. Moreover, quantitative real-time PCR (qRT-PCR) analysis indicated that expression of miR-21 increased in a time-dependent manner. TUNEL staining and Western blotting analysis showed that overexpression of miR-21 inhibited excessive hNSCs death induced by OGD treatment. Accordingly, knock down of miR-21 attenuated the neuroprotective effect observed in response to OGD treatment. Furthermore, JNK and p38 MAPKs inhibition was observed after overexpression of miR-21, and knock down of miR-21 had the opposite effect. We suggest that miR-21 prevents OGD-induced hNSCs death and apoptotic-associated protein activities through inhibiting JNK and p38 pathways in cultured hNSCs. Our findings may help to develop strategies for enhancing resident and transplanted NSCs survival after hypoxia-ischemic brain damage. PMID- 30291882 TI - Identification of Escherichia coli strains for the heterologous overexpression of soluble Clostridium difficile exosporium proteins. AB - Clostridium difficile infections are one of the leading causes of hospital acquired infections. C. difficile spores are considered the morphotype of transmission and recurrent infection due to its natural spore resistance properties. The outermost spore layer, the exosporium, provides the first contact with the environment and the host. However, molecular biology studies on exosporium proteins are lacking primarily due to difficulties in over-expressing these proteins under soluble conditions. In this work, we have developed a protocol to express soluble exosporium proteins of C. difficile spores in the heterologous Escherichia coli host. We found that the optimum soluble expression conditions may vary between 21, 30 and 37 degrees C, depending on the protein, and at least CdeC, BclA1 and BclA3, required E. coli strains that provided an oxidative environment such as Shuffle T7. These results will allow further studies with recombinant proteins of the exosporium of C. difficile spores. PMID- 30291883 TI - Therapeutic hypothermia after paediatric cardiac arrest: Pooled randomized controlled trials. AB - BACKGROUND: Separate trials to evaluate therapeutic hypothermia after paediatric cardiac arrest for out-of-hospital and in-hospital settings reported no statistically significant differences in survival with favourable neurobehavioral outcome or safety compared to therapeutic normothermia. However, larger sample sizes might detect smaller clinical effects. Our aim was to pool data from identically conducted trials to approximately double the sample size of the individual trials yielding greater statistical power to compare outcomes. METHODS: Combine individual patient data from two clinical trials set in forty one paediatric intensive care units in USA, Canada and UK. Children aged at least 48 h up to 18 years old, who remained comatose after resuscitation, were randomized within 6 h of return of circulation to hypothermia or normothermia (target 33.0 degrees C or 36.8 degrees C). The primary outcome, survival 12 months post-arrest with Vineland Adaptive Behaviour Scales, Second Edition (VABS II) score at least 70 (scored from 20 to 160, higher scores reflecting better function, population mean = 100, SD = 15), was evaluated among patients with pre arrest scores >=70. RESULTS: 624 patients were randomized. Among 517 with pre arrest VABS-II scores >=70, the primary outcome did not significantly differ between hypothermia and normothermia groups (28% [75/271] and 26% [63/246], respectively; relative risk, 1.08; 95% confidence interval [CI], 0.81 to 1.42; p = 0.61). Among 602 evaluable patients, the change in VABS-II score from baseline to 12 months did not differ significantly between groups (p = 0.20), nor did, proportion of cases with declines no more than 15 points or improvement from baseline [22% (hypothermia) and 21% (normothermia)]. One-year survival did not differ significantly between hypothermia and normothermia groups (44% [138/317] and 38% [113/ 297], respectively; relative risk, 1.15; 95% CI, 0.95 to 1.38; p = 0.15). Incidences of blood-product use, infection, and serious cardiac arrhythmia adverse events, and 28-day mortality, did not differ between groups. CONCLUSIONS: Analysis of combined data from two paediatric cardiac arrest targeted temperature management trials including both in-hospital and out-of-hospital cases revealed that hypothermia, as compared with normothermia, did not confer a significant benefit in survival with favourable functional outcome at one year. PMID- 30291884 TI - Number of treating team reviews prior to rapid response team activation. PMID- 30291885 TI - Evolution as a search for organizational equilibrium. AB - Evolution of living systems is a succession of historical changes in their equilibrium states. In the individual life cycle, every such state is realized as an equilibrium of developmental system, i.e. as its adult organizational norm. A trigger for a switching the system to a search for a new equilibrium is the loss under critical conditions of effective regulation of normal development towards uniform final state. This is manifested by replacement of the adult norm by its individual deviations. Thus, the organizational change begins with its adult state, which is the first to undergo the disturbance under new conditions. Accordingly, with the transition of the organization to a new equilibrium, the remodeling of the developmental system extends in generations from the adult stage to earlier ones. These premises contrast with the accepted belief that evolutionary events begin with individual changes in the germ cell. The only substantiated alternative to the last approach is objectively presented by the concepts of Schmalhausen and Waddington, in which the change in systemic organization starts with stabilization of selected phenotypic variations generated by violation of the current adult norm. The evolutionary spreading of organizational changes towards the early developmental stages constitutes in this case a natural consequence of the stabilization process. This course of events is actually reflected in different ways in the many empirical generalizations that have grown in the scope of more traditional views. It may be predicted that this pattern will come to provide a basis for a revised understanding of the evolutionary process. PMID- 30291887 TI - Axillary Transcatheter Aortic Valve Replacement in Patients With Peripheral Vascular Disease. AB - The axillary artery seems an interesting alternative in nonfemoral transaortic valve replacement (TAVR) patients. This study describes our experience with this technique and its short-term follow-up results. This is a retrospective single center study. All axillary TAVR performed in our department between 2015 and 2017 were included in the study. Mean follow-up was 13.2 +/- 9.5 months. All reporting was done according to the VARC-2 criteria. During the period covered, 43 patients had an axillary TAVR. Most patients were men (62.7%), had a mean age of 83.9 +/- 5.3 years and presented with EuroSCORE I, II, and STS score of 27.9 +/- 13.5%, 5.6 +/- 4.9%, and 7.7 +/- 4.05%, respectively. Vascular access was successful in all patients with a higher frequency of left approach (69.7%, n = 30). Both Medtronic CoreValve 37.2% (n = 16) and Edwards Sapien3 62.8% (n = 27) valves were used. An apical Certitude delivery system was preferentially used (24/27) in the latter group. There were no reported instances of valve migration or need for a second valve implantation. A single case (2.3%) of arterial vascular complication was reported. Central neurologic morbidity was 2.3%. No patient experienced brachial plexus injury. A pacemaker was implanted in 18.6% of cases (n = 8), with no significant difference between the 2 valves patient groups (S3 14.8% vs CV 25%, P 0.67). The 30-day mortality was 6.9% (n = 3) and 1-year survival was 86% [95% CI 72.6, 93.4]. Axillary TAVR is associated with acceptable morbidity, mortality, and leads to satisfactory short-term clinical outcomes. It has the potential to become the main alternative access route in nonfemoral TAVR patients. PMID- 30291886 TI - Biglycan gene connects metabolic dysfunction with brain disorder. AB - Dietary fructose is a major contributor to the epidemic of diabetes and obesity, and it is an excellent model to study metabolic syndrome. Based on previous studies that Bgn gene occupies a central position in a network of genes in the brain in response to fructose consumption, we assessed the capacity of Bgn to modulate the action of fructose on brain and body. We exposed male biglycan knockout mice (Bgn0/-) to fructose for 7 weeks, and results showed that Bgn0/- mice compensated for a decrement in learning and memory performance when exposed to fructose. These results were consistent with an attenuation of the action of fructose on hippocampal CREB levels. Fructose also reduced the levels of CREB and BDNF in primary hippocampal neuronal cultures. Bgn siRNA treatment abolished these effects of fructose on CREB and BDNF levels, in conjunction with a reduction in a fructose-related increase in Bgn protein. In addition, fructose consumption perturbed the systemic metabolism of glucose and lipids, that were also altered in the Bgn0/ mice. Transcriptomic profiling of hypothalamus, hippocampus, and liver supported the regulatory action of Bgn on key molecular pathways involved in metabolism, immune response, and neuronal plasticity. Overall results underscore the tissue-specific role of the extracellular matrix in the regulation of metabolism and brain function, and support Bgn as a key modulator for the impact of fructose across body and brain. PMID- 30291888 TI - Functional Evaluation of the Myocardial Ischemia after Coronary Artery Bypass Surgery using Coronary Flow Velocity Reserve in Left Ventricular Hypertrophy. AB - BACKGROUND: Patients with left ventricular hypertrophy (LVH) have reportedly higher than normal mortality and incidences of cardiovascular events. Coronary microvascular pathophysiology also appears to differ from other populations. Such coronary microcirculation dysfunctions are considered strong causes of cardiac events. OBJECTIVES: We compare the functional improvement of myocardial ischemia between LVH patients and other patients after successful coronary artery bypass surgery (CABG) using coronary flow velocity reserve (CFVR) by transthoracic echo cardiography. METHODS: Patients who underwent isolated coronary artery bypass surgery, including left anterior descending artery (LAD) revascularization via 'in-situ' internal thoracic artery (ITA) between June 2008 and July 2017 (n:155), were retrospectively reviewed. ITA grafts were patent in postoperative graft evaluation in all patients. Coronary flow velocity reserve was evaluated pre- and post-operatively, and data were compared between patients with severe left ventricular hypertrophy (LVH group) and those without (Non-LVH group). RESULTS: Preoperative mean CFVR was 1.77 +/- 0.75 in LVH group and 1.91 +/- 0.63 in Non LVH group (p=0.188). After the operation, ITA to LAD graft patency was confirmed in all patients. Postoperative CFVR was 2.23 +/- 0.70 in LVH group and 2.85 +/- 0.71 in Non-LVH group, respectively (p=0.002). Significant difference was observed between the two groups. CONCLUSION: CFVR values improved after ITA to LAD bypass grafting in both LVH and Non-LVH groups, but postoperative CFVR was significantly lower in patients with severe left ventricular hypertrophy than in patients without. Myocardial ischemia may exist in patients with left ventricular hypertrophy, despite patent graft, due to microvascular dysfunction. Comprehensive treatment, including long-term oral medication to improve microvascular dysfunction, is necessary for patients with left ventricular hypertrophy. PMID- 30291889 TI - Anaplastic large cell lymphoma of the palate: A case report. AB - Anaplastic large cell lymphoma (ALCL) is a very rare subtype of T-cell non Hodgkin's lymphoma (NHL). Similar to other types of NHL, ALCL primarily involves the nodal areas and sometimes it can involve several extranodal sites such as skin, lung and soft tissue. Primary oral involvement of systemic ALCL is very rare. We report a 55-year-old Thai female with anaplastic lymphoma kinase (ALK) negative ALCL primarily occurring at the hard palate. The patient was referred to the Department of Oral and Maxillofacial Surgery, Mahidol University, complaining of a swelling on her left palate. An incisional biopsy was performed and revealed a diffuse infiltration of large pleomorphic cells with prominent nuclei and sometimes eccentric horseshoe-shaped nuclei. The tumor cells showed a positivity for CD30, CD2, CD4, CD43 and EMA. A few tumor cells were positive to CD45 and CD3. They were negative for CD5, CD8, CD20, AE1/AE3, HMB45, ALK, TCRalphabeta, TCRgammadelta, and EBER. The patient reported a decrease in lesionsize after two courses of chemotherapy. However, approximately six months after beginning chemotherapy the tumor metastasized to the nasal cavities and brain. This case represented another rare systemic ALK-negative ALCL case primarily involving the oral cavity. PMID- 30291890 TI - Salvianolic acid B as an anti-emphysema agent I: In vitro stimulation of lung cell proliferation and migration, and protection against lung cell death, and in vivo lung STAT3 activation and VEGF elevation. AB - Emphysema causes progressive and life-threatening alveolar structural destruction/loss, yet remains irreversible and incurable to date. Impaired vascular endothelial growth factor (VEGF) signaling has been proposed as a new pathogenic mechanism, and if so, VEGF recovery may enable reversal of emphysema. Thus, we hypothesized that salvianolic acid B (Sal-B), a polyphenol in traditional Chinese herbal danshen, is an alveolar structural recovery agent for emphysema by virtue of VEGF stimulation/elevation via activation of Janus kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3), as stimulating lung cell proliferation and migration, and protecting against lung cell death. Using in vitro human lung microvascular endothelial (HMVEC-L) and alveolar epithelial (A549) cell systems, Sal-B was examined for 1) stimulation of cell proliferation by the MTT and BrdU assays; 2) promotion of cell migration by the scratch wound closure assay; 3) protection against emphysema-like induced cell death by the trypan blue exclusion and flow cytometry assays; and 4) mechanistic involvement of JAK2/STAT3/VEGF in these activities. Sal-B was also spray-dosed to the lungs of healthy rats for two weeks to verify the lung's STAT3 activation and VEGF elevation by western blot, as well as the absence of functional and morphological abnormalities. All the in vitro cell-based activities were concentration-dependent. At 25 MUM, Sal-B 1) stimulated cell proliferation by 1.4-2.6-fold; 2) promoted migratory cell wound closure by 1.5 1.7-fold; and 3) protected against cell death induced with H2O2 (oxidative stress) and SU5416 (VEGF receptor blockade) by 49-86%. JAK2 and STAT3 inhibitors and VEGF receptor antagonist each opposed these Sal-B's activities by over 65%, suggesting the mechanistic involvement of JAK2/STAT3 activation and VEGF stimulation/elevation. In rats, Sal-B at 0.2 mg/kg enabled 1.9 and 1.5-fold increased STAT3 phosphorylation and VEGF elevation in the lungs, respectively, while causing no functional and morphological abnormalities. Hence, Sal-B was projected to be a new class of anti-emphysema agent capable of reversing alveolar structural destruction/loss via JAK2/STAT3/VEGF-dependent stimulation of lung cell proliferation and migration, and inhibition of induced lung cell death.

AB - Patients with schizophrenia show impaired face and emotional expression processing that may be due to early perceptual deficits or late impairments in higher-order emotional facial recognition. This study examined event-related potentials (ERPs) in 23 patients with schizophrenia who experience auditory hallucinations and 19 healthy controls. EEG activity was recorded from 32 scalp sites positioned according to the 10-10 placement system. Linked left and right electrodes at the mastoids served as the reference. The P100, N170 and P300 were measured during an emotional facial identification task, which included neutral, joyful, sad, angry and fearful facial expressions and non-face stimuli (chairs). P100 was measured at O1/2 and P7/8. N170 was measured at P7/8. P300 was measured at Pz. Patients with schizophrenia were slower at identifying all facial expressions, including neutral ones. They also showed less positive P100 amplitude to sad, angry and fearful facial expressions. N170 amplitudes were smaller in patients in response to neutral, joyful, sad, angry, and fearful facial expression. Patients showed less positive P300 mean amplitudes to all facial expressions, including neutral ones. Within-group comparisons showed that patients exhibited a different pattern of ERP modulation across facial expressions than controls for P100 and N170, but not for P300. Our findings are compatible with the idea that behavioural and electrophysiological face processing deficits in schizophrenia arise from early-stage deficits in visual processing.

AB - Polyethyleneimine (PEI) has been used extensively for transient gene expression (TGE) in mammalian cell cultures. However, the relationship between DNA/PEI complex preparation and their biological activity has not been fully established. Here, a systematic study of DNA/PEI complexes, their physicochemical properties during formation and their transfection efficiency was performed on a virus-like particle (VLP) production platform. The same chemically defined cell culture medium for DNA/PEI complex formation was used as an alternative to simple ionic solutions to minimize changes in complex properties during transfection. Upon formation, an initial concentration of 1E + 10 DNA/PEI complexes/mL underwent partial aggregation with an average size of 300 nm. The participation of NaCl ions in the evolution of complexes was analyzed by X-ray spectroscopy, stressing the relevance of complexing media composition in TGE strategies. After 15 min incubation, 250 complexes plus aggregates per cell were estimated at the time of transfection. Such heterogeneous preparations cannot be easily characterized; subsequently, nanoparticle tracking analysis (NTA) and cryo-electron microscopy were combined to achieve a complete picture of the preparation. Finally, the contribution of each DNA/PEI complex subpopulation was tested by drug inhibition endocytosis. Interestingly, all complexes delivered DNA efficiently and high size aggregates, which enter through macropinocytosis, when inhibited presented a major contribution to transfection efficiency. There is a need to understand the physicochemical factors that participate in DNA delivery protocols. Hence, this study provides new insights into the characterization of DNA/PEI complexes that will assist in more productive and reproducible TGE strategies.

PMID- 30291894 TI - Challenges facing nanotoxicology and nanomedicine due to cellular diversity. AB - This review examines the interaction of nanomaterials (NMs) with cells from the perspective of major cellular differentiations. The structure and composition of cells reflect their role and function in a particular organ or environment. The normal differentiated-state and diseased cells may respond to NMs very differently. This review progresses with due care on nanotoxicology while emphasizing the potential of NMs in treating stress-associated disorders, including cancer and degeneration. The striking potential of NMs in inducing ROS, scavenging ROS, depleting cellular antioxidants, replenishing antioxidants, mimicking antioxidant enzyme activity, and modulating the immune system all show their considerable potential in treating cancer and other aging-associated disorders. It is now clear that NMs become more active and versatile when they come into contact with biological machinery, surprisingly in some cases, in a manner dependent on cell type. The mechanisms leading to the contrasting bioresponse of NMs ranging from toxicity to anticancer and from cell survival to carcinogenicity followed by their immuno-modulating potential show NMs to be a highly promising agent in biomedical therapy. This first-of-its-kind article seeks the challenges to be addressed that could provide a solid rationale in translating the promises of nanomedicine. A thorough understanding of normal and cancer biology could help to minimize the gap between basic and translational research in nanotechnology-based therapy. PMID- 30291895 TI - Sensitivity and colour intensity enhancement in lateral flow immunoassay tests by adjustment of test line position. AB - In this article, we have enhanced the sensitivity and limit of detection of lateral flow immunoassay tests, exemplified for the detection of human chorionic gonadotropin (pregnancy) through determination of proper test line position. Test line position affects the flow velocity and concentration profile of analytes at the test line, which itself impacts the reaction rate and thus the colour intensity. The flow velocity was precisely modelled, both analytically and numerically, and the predicted analytes' moving front (lateral) velocity was experimentally verified. Evolution of the velocity magnitude was determined to locate points with proper capillary velocity and accumulated bed-volume. This provides insights into the essence of LFIAs performance for simple and easy to practice improvements. The colour intensity was measured by quantifying the RGB of the resulting test line colours. The response colour intensity was enhanced for at least 20%, up to 40% by proper displacement of the test line position, and the limit of detection was cut by half to 10 IU/L. PMID- 30291896 TI - C-src tyrosine kinase gene rs1378942 polymorphism and hypertension in Asians: Review and meta-analysis. AB - BACKGROUND: The risk allele frequency of rs1378942 of c-src tyrosine kinase (CSK) gene is much higher in Asians (~ 0.80) than that in Europeans (~ 0.35), and the association between rs1378942 and blood pressure is controversial in Asians. Thus, the review and meta-analysis was performed to explore the effects of rs1378942 polymorphism on systolic blood pressure (SBP), diastolic blood pressure (DBP) levels and hypertension in Asians. METHODS: A literature search was conducted in electronic databases up to September 1, 2018. Beta, Odds Ratio (OR) and corresponding 95% confidence intervals (95%CI) were calculated to estimate the effects of rs1378942 on SBP, DBP and hypertension. Quanto software was used to estimate the statistical power. RESULTS: The results showed that the rs1378942 polymorphism significantly affected blood pressure levels in Asians, the C allele carriers had higher SBP and DBP levels: beta (95%CI): 0.71(0.38-1.04), P = 2.579 * 10-5, I2 = 43.5%, and beta (95%CI): 0.33(0.18-0.49), P = 2.092 * 10-5, I2 = 28.3%, respectively. This association was also found in East Asians, but not in South Asians. Furthermore, no significant association was observed with hypertension: OR (95%CI): 1.10 (0.97-1.25), P = .129, I2 = 81.2%. CONCLUSION: The meta-analysis demonstrates that the C allele of the CSK rs1378942 is associated with higher SBP and DBP levels in East Asians. PMID- 30291897 TI - Protein-based nanoparticles in cancer vaccine development. AB - Peptide and protein-based cancer vaccines usually fail to elicit efficient immune responses against tumors. However, delivery of these peptides and proteins as components within caged protein nanoparticles has shown promising improvements in vaccine efficacy. Advantages of protein nanoparticles over other vaccine platforms include their highly organized structures and symmetry, biodegradability, ability to be specifically functionalized at three different interfaces (inside and outside the protein cage, and between subunits in macromolecular assembly), and ideal size for vaccine delivery. In this review, we discuss different classes of virus-like particles and caged protein nanoparticles that have been used as vehicles to transport and increase the interaction of cancer vaccine components with the immune system. We review the effectiveness of these protein nanoparticles towards inducing and elevating specific immune responses, which are needed to overcome the low immunogenicity of the tumor microenvironment. PMID- 30291898 TI - Inorganic polyphosphate hydrolysis catalyzed by skeletal muscular actomyosin complexes is uncoupled with motility. AB - Hydrolysis of the triphosphate moiety of ATP, catalyzed by myosin, induces alterations in the affinity of the myosin heads for actin filaments via conformational changes, thereby causing motility of the actomyosin complexes. To elucidate the contribution of the triphosphate group attached to adenosine, we examined the enzymatic activity of heavy meromyosin (HMM) with actin filaments for inorganic tripolyphosphate (3PP) using a Malachite green method and evaluated using fluorescence microscopy the effects of 3PP on actin filament motility on HMM-coated glass slides. In the presence of MgCl2, HMM hydrolyzed 3PP at a maximum rate of 0.016 s-1 HMM-1, which was four times lower than the hydrolysis rate of ATP. Tetrapolyphosphate (4PP) was hydrolyzed at a rate similar to that of 3PP hydrolysis. The hydrolysis rates of 3PP and 4PP were enhanced by roughly 10 fold in the presence of actin filaments. In motility assays, the presence of polyphosphates did not lead to the sliding movement of actin filaments. Moreover, in the presence of ATP at low concentrations, the sliding velocity of actin filaments decreased as the concentration of added polyphosphate increased, indicating a competitive binding of polyphosphate to myosin heads with ATP. These results suggested that the energy produced by standalone triphosphate hydrolysis did not induce the unidirectional motion of actomyosin and that the link between triphosphate and adenosine was crucial for motility. PMID- 30291899 TI - Antithrombotic P2Y12 receptor antagonists: recent developments in drug discovery. AB - The P2Y12 receptor is one of eight known P2Y receptor subtypes, and belongs to the G-protein-coupled receptor (GPCR) family. The P2Y12 receptor is highly expressed on blood platelets and in the brain. Potent, selective, peripherally acting antagonists for the P2Y12 receptor are used clinically as antithrombotic drugs. Several different scaffolds have been identified as P2Y12 receptor antagonists, including irreversibly acting thienotetrahydropyridines (prodrugs), and reversible competitive antagonists, including adenine nucleotide analogs, piperazinyl-glutamate-quinolines, -pyridines, and -pyrimidines, and anthraquinone derivatives. Here, we provide an overview of the different scaffolds that have been developed as P2Y12 receptor antagonists, some of which have become important therapeutics. PMID- 30291900 TI - The future R&D landscape in non-alcoholic steatohepatitis (NASH). AB - Nonalcoholic steatohepatitis (NASH) is emerging as a major public health issue for the 21st century and is associated with significant liver-related morbidity and mortality. At present, there are no approved drug therapies for NASH. Consequently, NASH has become the focus of significant public and private research and development. In this review, we highlight the research and development (R&D) challenges and opportunities in this emerging therapeutic area. In particular, we consider the impact of the development of new biomarker strategies on clinical trial execution and design, and the positioning of single and combination therapies in future approaches to the treatment of NASH. PMID- 30291901 TI - First genome sequence of a blaKPC-2-carrying Citrobacter koseri isolate collected from a patient with diarrhoea. AB - OBJECTIVES: The blaKPC gene is rarely reported in Citrobacter koseri. Here we report the first draft genome sequence of a blaKPC-2-carrying C. koseri isolate from a patient with diarrhoea. METHODS: Transferability of the blaKPC-2-bearing plasmid was determined by the filter mating method. The whole genome sequence of C. koseri L168 was determined using an Illumina HiSeq platform. The genome was de novo assembled using Velvet 1.2.10. Acquired antimicrobial resistance genes and plasmid replicons were identified using ResFinder 2.1 and PlasmidFinder 1.3, respectively. RESULTS: Antimicrobial susceptibility testing (AST) showed that C. koseri L168 was resistant to multiple antibiotics but was susceptible to ciprofloxacin, gentamicin, tobramycin, amikacin, tigecycline and colistin. A KPC 2-harbouring plasmid was conjugative and the transconjugants conferred increased resistance to carbapenems confirmed by conjugation experiments and AST. In silico analysis revealed the presence of the beta-lactam resistance genes blaKPC-2 and blaMAL-1. Additionally, plasmids of incompatibility groups IncFII and IncX4 were identified in the genome by PlasmidFinder. BLAST analysis revealed that blaKPC-2 was located on a Tn3 transposon element in C. koseri L168 with the conserved linear structure ISKpn27-blaKPC-2-DeltaISKpn6-korC-klcA. CONCLUSIONS: To our knowledge, this is only the second report of C. koseri producing KPC-2, and we report the first draft genome sequence of a blaKPC-2-carrying C. koseri isolate from a patient with diarrhoea in China. This work may facilitate our understanding of the pathogenesis, multidrug resistance mechanisms and genomic features of this species. Further monitoring of bacteria carrying carbapenemase genes in patients' gut microbiota is warranted. PMID- 30291902 TI - Atopobium vaginae intrapartum bacteremia: A case report with a literature review. AB - Atopobium vaginae is an anaerobic Gram-positive bacterium recognized as a causative agent of bacterial vaginosis and associated with preterm delivery. Invasive infection and bacteremia have been rarely reported. We describe the case of a woman expecting her firstborn child who presented with a A. vaginae bacteremia during labor. Identification was performed using 16S rRNA gene sequencing. Both maternal and fetal outcomes were favorable due to the maternal treatment with amoxicillin-clavulanic acid. We identified three other cases in the literature with different fetal outcome. The genetic diversity of A. vaginae should be further explored in order to reveal potential strains with differential pathogenic potential. PMID- 30291903 TI - Characterization of the vaginal microbiota of Japanese women. AB - The composition of vaginal microbiota changes throughout life in response to health status, sexual activity, and pregnancy. Here the constitution of the vaginal microbiota among non-pregnant women, pregnant woman, and commercial sex workers (CSWs) in Japan were compared. Vaginal samples were obtained from 54 women between January 2014 and February 2015 and the microbiota of each was analyzed by 16S metagenomics as well as cluster and diversity analyses to identify differences. In addition, vaginal Lactobacillus spp. were isolated for comparison. Furthermore, data regarding the use of ritodrine hydrochloride by pregnant women was collected from medical charts. The vaginal microbiota were clustered into three groups. Group 1 was most often dominated by Lactobacillus spp., whereas groups 2 and 3 included not only Lactobacillus spp. but also Bifidobacterium, Atopobium, Prevotella, and Gardnerella spp., in addition to a few other taxa. In non-pregnant women, the proportions of microbes in groups 1, 2, and 3 were 31.8%, 36.4%, and 31.8%, respectively. In pregnant women, the abundance of group 1 microbes was notably greater than that of groups 2 and 3 (66.7% vs. 12.5% and 20.8%, respectively). In CSWs, the prevalence of group 3 microbes was far greater than that of group 1 (87.5% vs. 12.5%, respectively). The alpha diversity of non-pregnant women was significantly greater than that of pregnant women. The detection rate of live Lactobacillus spp. in CSWs was lower than in pregnant and non-pregnant women (25% vs. 50% and 68.2%, respectively). The vaginal microbiota of most pregnant women (60%) who received ritodrine hydrochloride was not dominated by Lactobacillus spp. These results suggest that there were clear differences in the colonization rate of Lactobacillus spp. among non-pregnant, pregnant, and CSW women groups. In addition, the dominance of Lactobacillus may influence the risk of preterm birth among women who received ritodrine hydrochloride during pregnancy. PMID- 30291904 TI - Waiting for a Pediatric Chronic Pain Clinic Evaluation: A Prospective Study Characterizing Waiting Times and Symptom Trajectories. AB - Chronic pain during childhood is prevalent and costly, but the access to interdisciplinary pain care is limited. Studies investigating adults waiting for pain clinic evaluation found that symptoms and quality of life deteriorate over the waiting period, but little is known about the experience of adolescents. Therefore, we aimed to determine wait list times and the longitudinal trends of pain and physical, mental, and social health over a 12-week period. In total, 97 adolescents, aged 10 to 18 years (M = 14.7 years, 82% female), waiting for evaluation at an interdisciplinary pediatric pain clinic completed assessments at enrollment and at 4-, 8-, and 12-week follow-up. We performed a review of the medical record of attendance patterns 12 months later. Twelve adolescents and their parents also completed qualitative interviews, describing their experience of waiting for evaluation. Wait times averaged 197.5 days (range = 69-758 days) from the time of referral to the first-attended appointment, and 86.6% of youths completed appointments. Longitudinal repeated measures analyses demonstrated little improvement in pain or other domains of functioning over the 12-week period. In qualitative interviews, families described anxious anticipation for the upcoming appointment, combined with frustration in waiting. Findings highlight the need to consider approaches to reduce wait times and provide early intervention for youths awaiting pain clinic evaluation. Perspective: This study extends the literature on the characteristics and symptom trajectories of adolescents during the wait period for interdisciplinary pain clinic evaluation, described previously only in adults with chronic pain. Findings demonstrated an average wait time of 6.5 months, during which youths' pain and physical and social health remained impaired. PMID- 30291905 TI - The Effects of Partners' Helping Motivation on Chronic Pain Patients' Functioning Over Time. AB - To understand when and why the provision of help by a partner of an individual with chronic pain (ICP) yields benefits, it is critical, according to self determination theory, to consider the extent to which partners' helping responses are supportive of the basic psychological needs of the ICP, as well as the motivations underlying these helping responses. The present study (N = 141 couples), spanning 3 measurement moments over 6 months, investigated temporal associations between partners' helping motivation, ICPs' psychological needs, and ICPs' functioning across time (ie, well-being, psychological distress, and disability). Results showed that partners' autonomous or volitional helping motivation (time 1) predicted decreases in ICPs' need frustration (time 2) and ICPs' need frustration (time 2) predicted increases in ICPs' psychological distress (time 3). Further, ICPs' need satisfaction (time 2) predicted increases in well-being (time 3) and decreases in psychological distress (time 3). The link between need frustration and ICPs' well-being (time 1-time 2) was bidirectional, with both relating reciprocally to one another over time. Finally, the associations between ICPs' disability and both partners' helping motivation and ICPs' need-based experiences were nonsignificant. Implications for research and clinical practice are discussed. Perspective: Partners' helping motivations and ICPs' psychological needs seem to be important to consider when investigating the role of spousal responses, because they could (indirectly) predict changes in the well-being and psychological distress of ICPs over time. PMID- 30291906 TI - Endothelins in inflammatory neurological diseases. AB - Endothelins were discovered more than thirty years ago as potent vasoactive compounds. Beyond their well-documented cardiovascular properties, however, the contributions of the endothelin pathway have been demonstrated in several neuroinflammatory processes and the peptides have been reported as clinically relevant biomarkers in neurodegenerative diseases. Several studies report that endothelin-1 significantly contributes to the progression of neuroinflammatory processes, particularly during infections in the central nervous system (CNS), and is associated with a loss of endothelial integrity at the blood brain barrier level. Because of the paucity of clinical trials with endothelin-1 antagonists in several infectious and non-infectious neuroinflammatory diseases, it remains an open question whether the 21 amino acid peptide is a mediator/modulator rather than a biomarker of the progression of neurodegeneration. This review focuses on the potential roles of endothelins in the pathology of neuroinflammatory processes, including infectious diseases of viral, bacterial or parasitic origin in which the synthesis of endothelins or its pharmacology have been investigated from the cell to the bedside in several cases, as well as in non-infectious inflammatory processes such as neurodegenerative disorders like Alzheimers Disease or central nervous system vasculitis. PMID- 30291907 TI - Fighting against depression with TREK-1 blockers: Past and future. A focus on spadin. AB - Depression is a devastating mood disorder and a leading cause of disability worldwide. Depression affects approximately one in five individuals in the world and represents heavy economic and social burdens. The neurobiological mechanisms of depression are not fully understood, but evidence highlights the role of monoamine neurotransmitter balance. Several antidepressants (ADs) are marketed to treat depression and related mood disorders. However, despite their efficacy, they remain nonspecific and unsafe because they trigger serious adverse effects. Therefore, developing new molecules for new targets in depression has become a real necessity. Eight years ago, spadin was described as a natural peptide with AD properties. This 17-amino acid peptide blocks TREK-1 channels, an original target in depression. Compared to the classical AD drugs such as fluoxetine, which requires 3-4 weeks for the AD effect to manifest, spadin acts rapidly within only 4 days of treatment. The AD properties are associated with increased neurogenesis and synaptogenesis in the brain. Despite the advantages of this fast acting AD, the in vivo stability is weak and does not last for >7 h. The present review summarizes different strategies such as retro-inverso strategy, cyclization, and shortening the spadin sequence that has led to the development and optimization of spadin as an AD. Shortened spadin analogs present increased inhibition potency for TREK-1, an improved AD activity, and prolonged in vivo bioavailability. Finally, we also discuss about other inhibitors of TREK-1 channels with a proven efficacy in treating depression in the clinic, such as fluoxetine. PMID- 30291908 TI - Acetylcholine signaling system in progression of lung cancers. AB - The neurotransmitter acetylcholine (ACh) acts as an autocrine growth factor for human lung cancer. Several lines of evidence show that lung cancer cells express all of the proteins required for the uptake of choline (choline transporter 1, choline transporter-like proteins) synthesis of ACh (choline acetyltransferase, carnitine acetyltransferase), transport of ACh (vesicular acetylcholine transport, OCTs, OCTNs) and degradation of ACh (acetylcholinesterase, butyrylcholinesterase). The released ACh binds back to nicotinic (nAChRs) and muscarinic receptors on lung cancer cells to accelerate their proliferation, migration and invasion. Out of all components of the cholinergic pathway, the nAChR-signaling has been studied the most intensely. The reason for this trend is due to genome-wide data studies showing that nicotinic receptor subtypes are involved in lung cancer risk, the relationship between cigarette smoke and lung cancer risk as well as the rising popularity of electronic cigarettes considered by many as a "safe" alternative to smoking. There are a small number of articles which review the contribution of the other cholinergic proteins in the pathophysiology of lung cancer. The primary objective of this review article is to discuss the function of the acetylcholine-signaling proteins in the progression of lung cancer. The investigation of the role of cholinergic network in lung cancer will pave the way to novel molecular targets and drugs in this lethal malignancy. PMID- 30291909 TI - Increased Mortality Among Patients With vs Without Cirrhosis and Autoimmune Hepatitis. AB - BACKGROUND & AIMS: There have been few reproducible studies of mortality in patients with autoimmune hepatitis (AIH) and its variants. We calculated mortality in a large national cohort of patients with AIH, with vs without cirrhosis, in the Netherlands. METHODS: We collected data from 449 patients with established AIH (77% female), from 6 academic and 10 non-academic hospitals in the Netherlands. We identified 29 patients with AIH and primary biliary cholangitis and 35 patients with AIH and primary sclerosing cholangitis (AIH PSC). Mortality and liver transplantation data were assessed from August 1, 2006 through July 31, 2016. Standardized mortality ratios (SMR) were calculated using age-, sex-, and calendar year-matched mortality for the general Dutch population. RESULTS: During the 10-year follow-up period, 60 patients (13%) died (mean age, 71 years; range, 33-94 years). Twenty-six causes of death were liver related (43%), whereas the others could not be attributed to liver disease. Patients with AIH and cirrhosis had significantly higher mortality than the general population (SMR, 1.9; 95% CI, 1.2-3.4), whereas patients without cirrhosis did not (SMR, 1.2; 95% CI, 0.8-1.8). Patients with AIH-PSC had the largest increase in mortality, compared to the general population (SMR, 4.7; 95% CI, 1.5-14.6), of all groups analyzed. Mortality in patients with AIH and primary biliary cholangitis was not greater than the general population. Four or more relapses per decade or not achieving remission was associated with an increase in liver related death or liver transplantation. Nine patients underwent liver transplantation; 2 died from non-liver related causes. Four of 9 patients on the waitlist for transplantation died before receiving a donated liver. CONCLUSION: In an analysis of data from a large national cohort of patients with AIH, we found increased mortality of patients with cirrhosis, but not of patients without cirrhosis, compared to the general Dutch population. Survival was significantly reduced in patients with AIH and features of concurrent PSC. PMID- 30291910 TI - No Change in Determining Crohn's Disease Recurrence or Need for Endoscopic or Surgical Intervention With Modification of the Rutgeerts Scoring System. AB - The postoperative endoscopic recurrence score, commonly referred to as the Rutgeerts score, was designed to predict clinical recurrence risk in Crohn's disease (CD) patients undergoing ileocolonic resection based on early endoscopic findings at the anastomosis and in the neoterminal ileum.1 In the pivotal publication, the i2 category, including aphthous lesions in the terminal ileum as well as ileocolonic anastomosis lesions, had a heterogeneous recurrence risk. Because anastomotic ulcers were suspected to be postsurgical ischemic lesions and less predictive of progressive disease,2 a modified Rutgeerts score (mRS) was proposed: i2a, lesions confined to the anastomosis +/-<5 isolated aphthous ulcers in the ileum; i2b, more than 5 aphthous ulcers in the ileum with normal mucosa in between, +/- anastomotic lesions.3,4. PMID- 30291911 TI - Augmentation of NAD+ levels by enzymatic action of NAD(P)H quinone oxidoreductase 1 attenuates adriamycin-induced cardiac dysfunction in mice. AB - BACKGROUND: Adriamycin (ADR) is a powerful chemotherapeutic agent extensively used to treat various human neoplasms. However, its clinical utility is hampered due to severe adverse side effects i.e. cardiotoxicity and heart failure. ADR induced cardiomyopathy (AIC) has been reported to be caused by myocardial damage and dysfunction through oxidative stress, DNA damage, and inflammatory responses. Nonetheless, the remedies for AIC are even not established. Therefore, we illustrate the role of NAD+/NADH modulation by NAD(P)H quinone oxidoreductase 1 (NQO1) enzymatic action on AIC. METHODS AND RESULTS: AIC was established by intraperitoneal injection of ADR in C57BL/6 wild-type (WT) and NQO1 knockout (NQO1-/-) mice. All Mice were orally administered dunnione (named NQO1 substrate) before and after exposure to ADR. Cardiac biomarker levels in the plasma, cardiac dysfunction, oxidative biomarkers, and mRNA and protein levels of pro inflammatory mediators were determined compared the cardiac toxicity of each experimental group. All biomarkers of Cardiac damage and oxidative stress, and mRNA levels of pro-inflammatory cytokines including cardiac dysfunction were increased in ADR-treated both WT and NQO1-/- mice. However, this increase was significantly reduced by dunnione in WT, but not in NQO1-/- mice. In addition, a decrease in SIRT1 activity due to a reduction in the NAD+/NADH ratio by PARP-1 hyperactivation was associated with AIC through increased nuclear factor (NF) kappaB p65 and p53 acetylation in both WT and NQO1-/- mice. While an elevation in NAD+/NADH ratio via NQO1 enzymatic action using dunnione recovered SIRT1 activity and subsequently deacetylated NF-kappaB p65 and p53, however not in NQO1-/- mice, thereby attenuating AIC. CONCLUSION: Thus, modulation of NAD+/NADH by NQO1 may be a novel therapeutic approach to prevent chemotherapy-associated heart failure, including AIC. PMID- 30291912 TI - 11beta-hydroxysteroid dehydrogenase type 1 inhibitor attenuates high-fat diet induced cardiomyopathy. AB - BACKGROUND: High-fat diet (HFD) induces cardiac hypertrophy; however, the underlying cellular and molecular mechanisms are yet unclear. In the present study, we investigated the roles of 11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1), an amplifier of local glucocorticoid activity, in the pathogenesis of cardiac dysfunction. METHODS: Male Wistar rats were fed normal chow diet (NC) or HFD and examined the cardiac remolding and functional alteration by echocardiography and histology. Primary neonatal rat ventricular cardiomyocytes (NRCMs) treated with palmitic acid (PA) or infected by lentivirus were used for identifying the role by 11beta-HSD1 in cardiac hypertrophy. Genome microarray of NRCMs was performed to further reveal the mechanism underlying cardiac dysfunction. RESULTS: Palmitic acid induced hypertrophy in NRCMs that upregulated 11beta-HSD1 expression in cardiomyocytes, which led to a significant enlargement in the cell size and expression of cardiac hypertrophy-specific genes. Conversely, a remarkable decrease in cardiomyocytes size was detected in either BVT.2733 (a selective inhibitor of 11beta-HSD1)-treated or 11beta-HSD1-deficient NRCMs. Furthermore, both glucocorticoid receptor (GR) antagonist RU486 and mineralocorticoid receptor (MR) antagonist spironolactone markedly attenuated the 11beta-HSD1-induced cardiomyocytes hypertrophy. Genome microarray revealed that cAMP and calcium signaling pathways are potential downstream signaling pathways regulated by 11beta-HSD1 in cardiomyocytes hypertrophy. Similar to in vitro results, BVT.2733 strikingly attenuated cardiac hypertrophy and improved cardiac function in HFD-fed rats. CONCLUSION: 11beta-HSD1 acts as an important regulator that controls the cardiac remolding via both GR and MR and the pharmacological inhibition of 11beta-HSD1 could be a new therapeutic approach in preventing HFD induced cardiac hypertrophy. PMID- 30291913 TI - Comparative Genomic Profiling of Refractory/Metastatic Penile and non-Penile Cutaneous Squamous Cell Carcinoma: Implications for Selection of Systemic Therapy. AB - BACKGROUND: Metastatic penile squamous cell carcinoma (mPSCC) is an aggressive malignancy with limited treatment options. We compared the potential therapy impacting genomic alterations (GA) between mPSCC and non-penile cutaneous metastatic squamous cell carcinoma (mCSCC). METHODS: DNA was extracted from 40 microns of FFPE samples from 78 cases of mPSCC and 338 mCSCC. Comprehensive genomic profiling (CGP), was performed using a hybrid-capture, adaptor ligation based next generation sequencing assay to a mean coverage depth of >500X. Tumor mutational burden (TMB) was determined on 1.1 Mbp of sequenced DNA and microsatellite instability (MSI) was determined on 114 loci. RESULTS: Potential targeted therapy opportunities in mPSCC included alterations in MTOR pathway (NF1 GA in 7% and PTEN GA in 4%) and DNA repair pathway (BRCA2 and ATM GA, each in 7%) and tyrosine kinase (EGFR GA in 6%; FGFR3 and ERBB2 GA each in 4%). TMB was significantly higher in the predominantly UV light exposed mSCC than mPSCC, making mSCC potentially more responsive to immunotherapies than mPSCC. MSI-High status was extremely rare for both mPSCC and mCSCC. CD274 (PD-L1) amplification was also rare in both tumor types. CONCLUSIONS: mPSCC is a unique subtype of SCC with distinctive genomic features that contrast with those identified in mCSCC of non-penile UV light exposed skin. Although not rich in predictors for response to immunotherapy (low TMB and MSI low), more than one quarter of mPSCC may potentially benefit from existing and available therapies targeting MTOR, DNA repair, and Tyrosine Kinase pathways.

AB - PURPOSE: Percent parenchymal mass-preserved (PPMP) is the primary determinant of functional outcomes after partial nephrectomy (PN). Accurate methods for predicting PPMP based on preoperative imaging could facilitate patient counseling. MATERIALS/METHODS: 428 PN patients with necessary studies to assess ipsilateral parenchymal mass/function preserved were evaluated. Preoperative/postoperative ipsilateral parenchymal mass were measured from contrast-enhanced CT<2 months prior and 3-12 months after PN and actual-PPMP was determined. Ipsilateral-PPMP and final global-GFR were estimated based on preoperative imaging using subjective estimation (SE), quantitative estimation (QE), or estimation derived from contact surface area (CSA) or R.E.N.A.L. RESULTS: Median tumor diameter was 3.5cm. Median CSA/R.E.N.A.L. were 24cm2 and 8, respectively. Median actual ipsilateral-PPMP and percent global-GFR preserved were 84%/89%, respectively. Median estimated ipsilateral-PPMP was 85%/87%/88%/83% based on SE/QE/CSA/R.E.N.A.L., respectively. Correlations between actual-PPMP and estimated-PPMP were relatively weak in all instances, (all r<=0.46). Prediction of final global-GFR was strong for all 4 methods (all r=0.91); however, similarly strong correlation was also obtained when presuming that 89% of the preoperative global-GFR will be saved in each case (r=0.91). On multivariable analyses, solitary-kidney, preoperative-GFR, and various estimates of PPMP significantly associated with final global-GFR. However, preoperative-GFR proved to be the strongest predictor; it was >10-fold more impactful than estimated-PPMP or solitary-kidney. CONCLUSIONS: Currently available methods for estimating PPMP have important limitations. Final global-GFR, the most important functional outcome, can be predicted fairly accurately by all of the tested methods but none are better than simply presuming that 89% of function will be saved, due to strong anchoring to preoperative-GFR.

AB - Traditional Greek Graviera cheese is often produced from thermized milk to control undesirable bacterial contaminants. Since thermization also reduces the desirable lactic acid bacteria (LAB) microbiota of raw milk, natural undefined or commercially defined starters are used. This study evaluated effects of the type of starter added to bulk thermized milk on the microbiology of mature (day-90) Graviera cheese. Cheeses produced with a natural starter culture (NSC) in non concentrated yogurt-like form or a commercial starter culture (CSC) containing Streptococcus thermophilus and various Lactococcus lactis strains in concentrated freeze-dried form, were analyzed microbiologically, and 200 LAB isolates (100 from each type of cheese) were identified. The LAB microbiota of the mature CSC cheeses was dominated by nonstarter strains of Lactobacillus paracasei and Lb. plantarum whereas indigenous Enterococcus faecium and E. durans strains of high phenotypic and genotypic diversity predominated in the respective NSC-cheeses. Populations of enterococci in CSC-cheeses were subdominant by 10 to 100-fold compared with those in NSC-cheeses; E. faecium was the most frequently isolated Enterococcus species from the mature CSC-cheeses. Sporadic or no isolates of other LAB species, including the commercial S. thermophilus and Lc. lactis starter strains in the CSC-cheeses and the natural S. thermophilus and Lactobacillus delbrueckii subsp. bulgaricus starter strains plus indigenous Lactococcus, Leuconostoc and E. faecalis in the NSC-cheeses, were detected. In conclusion, the replacement of the NSC with the CSC controlled growth of dairy enterococci in favor of mesophilic nonstarter lactobacilli during ripening. While safety concerns associated with the inefficiency of NSCs to prevent outgrowth of indigenous enterococci suggest that CSCs should be preferred by traditional Greek Graviera cheese processors, panel sensory evaluations showed that the NSC-ripened cheeses were of slightly lower appearance but of occasionally higher flavor scores than the CSC-ripened cheeses. PMID- 30291918 TI - Effect of different font sizes and of spaces between words on eye movement performance: An eye tracker study in dyslexic and non-dyslexic children. AB - The aim of the present study was to explore the possible change in eye movement performance in a group of dyslexic and non-dyslexic children reading four lines of a text with different font sizes and spaces between the words. Fifteen dyslexic children from 7 to 12 years old and two groups of fifteen non-dyslexic children, respectively reading and chronological age-matched group, participated in this study. Horizontal eye movements from both eyes were recorded by a video system (EyeBrain T2(r)) while the children were reading a text. Three different texts were used with different font sizes and spaces between words. Results showed that increasing font size and character spacing significantly reduced duration of the fixation and increased the number and amplitude of prosaccades in all groups of children tested. Interestingly, while reading texts in which the letters were larger and more spaced (Texts 2 and 3), the duration of fixations in dyslexic and in non-dyslexic children groups decreased, becoming similar to those reported in the non-dyslexic children group. We suggest that large letter spacing between words could be employed in schools to help dyslexic children in order to ameliorate their reading performance. PMID- 30291919 TI - These are the people in your neighbourhood: Consistency and persistence in infants' exposure to caregivers', relatives', and strangers' faces across contexts. AB - Faces are a frequent part of young infants' visual environments. Three-month-old infants spend approximately 25% of their time exposed to faces (Sugden, Mohamed Ali, & Moulson, 2014; Jayaraman, Fausey, & Smith, 2015). These faces belong primarily to familiar people, like their caregivers, and are heavily weighted towards female, adult-aged, and own-race faces. To date, descriptions of infants' exposure to faces have focused on frequency-both overall frequency and relative frequency of different face types (e.g., familiar vs. unfamiliar; own-race vs. other-race). It is less clear whether faces of different types distinguish themselves in other ways that have implications for infants' learning. Here, we move beyond an evaluation of frequency to determine the dimensions by which familiar faces (i.e., caregivers and relatives, as identified by parental report) differentiate themselves from unfamiliar (i.e., stranger's) faces in the infant's early visual environment. Measuring infants' natural visual ecology with head mounted infant-perspective cameras, we found that 3-month-olds were exposed to faces 21% of the time. The primary caregiver was the most frequent face (44% of exposure time) and non-primary caregivers were often second most frequent (17% of exposure time). Caregiver faces also distinguished themselves by their consistency across both contexts and time. For example, the primary caregiver's face was most likely to appear across contexts and locations. Primary caregiver faces were less likely to persist in the field of view, as compared to non primary caregiver and stranger faces. Thus, the socially important faces in the infant's visual environment distinguish themselves not only through their overall frequency, but also through their consistency across contexts. This has implications for understanding how the early visual environment shapes learning about faces. PMID- 30291920 TI - Estimates of edge detection filters in human vision. AB - Edge detection is widely believed to be an important early stage in human visual processing. However, there have been relatively few attempts to map human edge detection filters. In this study, observers had to locate a randomly placed step edge in brown noise (the integral of white noise) with a 1/f2 power spectrum. Their responses were modelled by assuming the probability the observer chose an edge location depended on the response of their own edge detection filter to that location. The observer's edge detection filter was then estimated by maximum likelihood methods. The filters obtained were odd-symmetric and similar to a derivative of Gaussian, with a peak-to-trough width of 0.1-0.15 degrees. These filters are compared with previous estimates of edge detectors in humans, and with neurophysiological receptive fields and theoretical edge detectors. PMID- 30291921 TI - pH dependent membrane binding of the Solanum tuberosum plant specific insert: An in silico study. AB - The Solanum tuberosum plant-specific insert (StPSI) has been shown to possess potent antimicrobial activity against both human and plant pathogens. Furthermore, in vitro, the StPSI is capable of fusing phospholipid vesicles, provided the conditions of net anionic vesicle charge and acidic pH are met. Constant pH replica-exchange simulations indicate several acidic residues on the dimer have highly perturbed pKas (<3.0; E15, D28, E85 & E100) due to involvement in salt bridges. After setting the pH of the system to either 3.0 or 7.4, all atom simulations provided details of the effect of pH on secondary structural elements, particularly in the previously unresolved crystallographic structure of the loop section. Coarse-grained dimer-bilayer simulations demonstrated that at pH 7.4, the dimer had no affinity for neutral or anionic membranes over the course of 1 MUs simulations. Conversely, at pH 3.0 two binding modes were observed. Mode 1 is mediated primarily via strong N-terminal interactions on one monomer only, whereas in mode 2, N- and C-terminal residues of one monomer and numerous polar and basic residues on the second monomer, particularly in the third helix, participate in membrane interactions. Mode 2 was accompanied by re orientation of the dimer to a more vertical position with respect to helices 1 and 4, positioning the dimer for membrane interactions. These results offer the first examination at near-atomic resolution of residues mediating the StPSI membrane interactions, and allow for the postulation of a possible fusion mechanism. PMID- 30291922 TI - VDAC electronics: 5. Mechanism and computational model of hexokinase-dependent generation of the outer membrane potential in brain mitochondria. AB - Glycolysis plays a key role in brain energy metabolism. The initial and rate limiting step of brain glycolysis is catalyzed mainly by hexokinase I (HKI), the majority of which is bound to the mitochondrial outer membrane (MOM), mostly through the mitochondrial inter-membrane contact sites formed by the voltage dependent anion channel (VDAC, outer membrane) and the adenine nucleotide translocator (ANT, inner membrane). Earlier, we proposed a mechanism for the generation of the mitochondrial outer membrane potential (OMP) as a result of partial application of the inner membrane potential (IMP) to MOM through the electrogenic ANT-VDAC-HK inter-membrane contact sites. According to this previous mechanism, the Gibbs free energy of the hexokinase reaction might modulate the generated OMP (Lemeshko, Biophys. J., 2002). In the present work, a new computational model was developed to perform thermodynamic estimations of the proposed mechanism of IMP-HKI-mediated generation of OMP. The calculated OMP was high enough to electrically regulate MOM permeability for negatively charged metabolites through free, unbound VDACs in MOM. On the other hand, the positive inside polarity of OMP generated by the IMP-HKI-mediated mechanism is expected to protect mitochondria against elevated concentrations of cytosolic Ca2+. This computational analysis suggests that metabolically-dependent generation of OMP in the brain mitochondria, controlled by many factors that modulate VDAC1-HKI interaction, VDAC's voltage-gating properties and permeability, might represent one of the physiological mechanisms of regulation of the brain energy metabolism and of neuronal death resistance, and might also be involved in various neurodegenerative disorders, such as Alzheimer's disease. PMID- 30291923 TI - Acylation of the S413-PV cell-penetrating peptide as a means of enhancing its capacity to mediate nucleic acid delivery: Relevance of peptide/lipid interactions. AB - BACKGROUND: Cell-penetrating peptides (CPPs) have been extensively exploited in gene therapy approaches as vectors for intracellular delivery of bioactive molecules. The ability of CPPs to be internalized into cells and their capacity to complex nucleic acids depend on their molecular structure, both primary and secondary, namely regarding hydrophobicity/hydrophilicity. CPP acylation has been used as a strategy to improve this structural feature. METHODS: Acyl groups (from 6 to 18 carbon atoms) were attached to the S413-PV peptide and their effects on the peptide competence to complex siRNAs and to mediate gene silencing in glioblastoma (GBM) cells were studied. A systematic characterization of membrane interactions with S413-PV acyl-derivatives was also conducted, using different biophysical techniques (surface pressure-area isotherms in Langmuir monolayers, DSC and 31P NMR) to unravel a relationship between CPP biological activity and CPP effects on membrane stability and lipid organization. RESULTS: A remarkable concordance was noticed between acylated-S413-PV peptide competence to promote gene silencing in GBM cells and disturbance induced in membrane models, the lauroyl- and myristoyl-S413-PV peptides being the most effective. A cut-off effect was described for the first time regarding the influence of acyl-chain length on CPP bioactivity. CONCLUSIONS: C12-S413-PV showed high capacity to destabilize lipid bilayers, to escape from lysosomal degradation and to mediate gene silencing without promoting cytotoxicity. GENERAL SIGNIFICANCE: Besides unraveling a new CPP with high potential to be employed as a gene delivery vector, this work emphasizes the benefit from allying biophysical and biological studies towards a proper CPP structural refinement for successful pre clinical/clinical application. PMID- 30291924 TI - Lipid bilayers cushioned with polyelectrolyte-based films on doped silicon surfaces. AB - Silicon semiconductors with a thin surface layer of silica were first modified with polyelectrolytes (polyethyleneimine, polystyrene sulfonate and poly(allylamine)) via a facile layer-by-layer deposition approach. Subsequently, lipid vesicles were added to the preformed polymeric cushion, resulting in the adsorption of intact vesicles or fusion and lipid bilayer formation. To study involved interactions we employed optical reflectometry, electrochemical impedance spectroscopy and fluorescent recovery after photobleaching. Three phospholipids with different charge of polar head groups, i.e. 1,2-dioleoyl-sn glycero-3-phosphocholine (DOPC), 1,2-dioleoyl-sn-glycero-3-phospho-l-serine (DOPS) and 1,2-dioleoyl-3-trimethylammonium-propane (DOTAP) were used to prepare vesicles with varying surface charge. We observed that only lipid vesicles composed from 1:1 (mole:mole) mixture of DOPC/DOPS have the ability to fuse onto an oppositely charged terminal layer of polyelectrolyte giving a lipid bilayer with a resistance of >100 kOmega. With optical reflectometry we found that the vesicle surface charge is directly related to the amount of mass adsorbed onto the surface. An interesting observation was that zwitterionic polar head groups of DOPC allow the adsorption on both positively and negatively charged surfaces. As found with fluorescent recovery after photobleaching, positively charged surface governed by the presence of poly(allylamine) as the terminal layer resulted in intact DOPC lipid vesicles adsorption whereas in the case of a negatively charged silica surface formation of lipid bilayers was observed, as expected from literature. PMID- 30291925 TI - Chest CT Scan at Radiation Dose of a Posteroanterior and Lateral Chest Radiograph Series: A Proof of Principle in Lymphangioleiomyomatosis. AB - BACKGROUND: Given the rising utilization of medical imaging and the risks of radiation, there is increased interest in reducing radiation exposure. The objective of this study was to evaluate, as a proof of principle, CT scans performed at radiation doses equivalent to that of a posteroanterior and lateral chest radiograph series in the cystic lung disease lymphangioleiomyomatosis. METHODS: From November 2016 to May 2018, 105 consecutive subjects with lymphangioleiomyomatosis received chest CT scans at standard and ultra-low radiation doses. Standard and ultra-low dose images, respectively, were reconstructed with routine iterative and newer model-based iterative reconstruction. Lymphangioleiomyomatosis severity can be quantified as cyst score (percentage of lung occupied by cysts), an ideal benchmark for validating CT scans performed at a reduced dose compared with a standard dose. Cyst scores were quantified using semi-automated software and evaluated by linear correlation and Bland-Altman analysis. RESULTS: Overall, ultra-low dose CT scans represented a 96% dose reduction, with a median dose equivalent to 1 vs 22 posteroanterior and lateral chest radiograph series (0.14 mSv; 5th-95th percentile, 0.10-0.20 vs standard dose 3.4 mSv; 5th-95th percentile, 1.5-7.4; P < .0001). The mean difference in cyst scores between ultra-low and standard dose CT scans was 1.1% +/- 2.0%, with a relative difference in cyst score of 11%. Linear correlation coefficient was excellent at 0.97 (P < .0001). CONCLUSIONS: In lymphangioleiomyomatosis, chest CT scan at substantial radiation reduction to doses equivalent to that of a posteroanterior and lateral chest radiograph series provides similar cyst score quantification as standard dose CT scan.

PMID- 30291926 TI - Building a Prediction Model for Radiographically Confirmed Pneumonia in Peruvian Children: From Symptoms to Imaging. AB - BACKGROUND: Community-acquired pneumonia remains the leading cause of death in children worldwide, and current diagnostic guidelines in resource-poor settings are neither sensitive nor specific. We sought to determine the ability to correctly diagnose radiographically confirmed clinical pneumonia when diagnostics tools were added to clinical signs and symptoms in a cohort of children with acute respiratory illnesses in Peru. METHODS: Children < 5 years of age with an acute respiratory illness presenting to a tertiary hospital in Lima, Peru, were enrolled. The ability to predict radiographically confirmed clinical pneumonia was assessed using logistic regression under four additive scenarios: clinical signs and symptoms only, addition of lung auscultation, addition of oxyhemoglobin saturation (Spo2), and addition of lung ultrasound. RESULTS: Of 832 children (mean age, 21.3 months; 59% boys), 453 (54.6%) had clinical pneumonia and 221 (26.6%) were radiographically confirmed. Children with radiographically confirmed clinical pneumonia had lower average Spo2 than those without (95.9% vs 96.6%, respectively; P < .01). The ability to correctly identify radiographically confirmed clinical pneumonia using clinical signs and symptoms was limited (area under the curve [AUC] = 0.62; 95% CI, 0.58-0.67) with a sensitivity of 66% (95% CI, 59%-73%) and specificity of 53% (95% CI, 49%-57%). The addition of lung auscultation improved classification (AUC = 0.73; 95% CI, 0.69-0.77) with a sensitivity of 75% (95% CI, 69%-81%) and specificity of 53% (95% CI, 49%-57%) for the presence of crackles. In contrast, the addition of Spo2 did not improve classification (AUC = 0.73; 95% CI, 0.69-0.77) with a sensitivity of 40% (95% CI, 33%-47%) and specificity of 72% (95% CI, 68%-75%) for an Spo2 <= 92%. Adding consolidation on lung ultrasound was associated with the largest improvement in classification (AUC = 0.85; 95% CI, 0.82-0.89) with a sensitivity of 55% (95% CI, 48%-63%) and specificity of 95% (95% CI, 93%-97%). CONCLUSIONS: The addition of lung ultrasound and auscultation to clinical signs and symptoms improved the ability to correctly classify radiographically confirmed clinical pneumonia. Implementation of auscultation- and ultrasound-based diagnostic tools can be considered to improve diagnostic yield of pneumonia in resource-poor settings. PMID- 30291928 TI - Controlled release of cephradine by biopolymers based target specific crosslinked hydrogels. AB - The novel silane crosslinked (TEOS) hydrogels based on eco-friendly biodegradable chitosan/guargum were prepared by blending with PEG to develop pH sensitive hydrogels (CGP) and achieved its hydrophilicity and target specificity for controlled release of drug. The crosslinker amount was varied to analyze its effect on the hydrogel properties and were characterized using FTIR, SEM, TGA, swelling studies (water, buffer and ionic solution) and in-vitro release of cephradine (CED). FTIR confirmed the presence of characteristic peaks and crosslinking between the components while SEM images showed the formation of clear micro- and macro-pores. The swelling behavior in water showed that compared to the controlled hydrogel, the crosslinked hydrogels revealed more swelling but a decrease in swelling with further increase in the amount of crosslinker was observed. The hydrogels showed low swelling at basic and neutral pH while maximum swelling was observed at acidic pH. This pH response made these hydrogels an ideal candidate for injectable controlled release. The CED was loaded on hydrogels and its release mechanism was studied in PBS, SGF and SIF which revealed that out of all hydrogels (CGP100, CGP150, CGP200 and CGP250), CGP100 has shown CED release of 85% in 130 min in PBS and 82.4% in SIF. PMID- 30291929 TI - Physiochemical characteristics and bone/cartilage tissue engineering potentialities of protein-based macromolecules - A review. AB - Protein-based macromolecules such as keratin, silk fibroin, collagen, gelatin, and fibrin have emerged as potential candidate materials with unique structural and functional characteristics. Despite many advantages, the development of tissue-engineered constructs that can match the biological context of real tissue matrix remains a challenge in tissue engineering (TE). The tissue-engineered constructs should also support vascularization. Protein-based macromolecules, in pristine or combine form, provide a promising platform to engineer constructs with unique design and functionalities which are highly essential for an appropriate stimulation and differentiation of cells in a specific TE approach. However, much work remains to be undertaken with particular reference to in-depth interactions between constructed cues and target host tissues. Thus, modern advancements are emphasizing to understand critiques and functionalization of protein-based macromolecule that organize not only cellular activities but also tissue regenerations. In this review, numerous physicochemical, functional, and structural characteristics of protein-based macromolecules such as keratin, silk fibroin, collagen, gelatin, and fibrin are discussed. This review also presents the hope vs. hype phenomenon for tissue engineering. Later part of the review focuses on different requisite characteristics and their role in TE. The discussion presented here could prove highly useful for the construction of scaffolds with requisite features. PMID- 30291930 TI - Study of the mechanical degradation mechanism of guar gum in turbulent flow by FTIR. AB - Guar gum is used in low concentrations as a drag reducing agent in turbulent flows to significantly accelerate flow in oil pipelines, oil well operations and aqueous systems. Drag reduction also promotes a decrease in energy demand in pumping systems. However, the polymers undergo mechanical degradation and lose the ability to promote drag reduction over time. In this paper, the drag reduction, the power required by the pumps and the degradation of the guar gum were evaluated during a turbulent flow of an aqueous solution containing the biopolymer. The results indicate the mechanism of degradation of guar gum by the hydrolysis of the bond alpha (1 -> 6), liberating the galactose, which justice to the loss of efficiency throughout the process. An understanding of this mechanism should allow for the development of more mechanically resistant polymers and the increase of drag reduction capacity over time. PMID- 30291931 TI - A review on injectable chitosan/beta glycerophosphate hydrogels for bone tissue regeneration. AB - Tissue engineering (TE) is a promising approach for repairing diseased and damaged bone tissue. Injectable hydrogel based strategies offer a wide range of applications in rapid recovery of bone defects by acting as filler materials and depots for delivering various bioactive molecules and averting the need for surgical intervention. Chitosan (CS), a natural polysaccharide, forms a thermosensitive injectable hydrogel through the addition of beta-glycerophosphate (beta-GP). This hybrid hydrogel possesses numerous advantages namely mimicking native extracellular matrix (ECM) and providing an amenable microenvironment for cell growth. In this review, a brief insight into the gelation mechanism of CS/GP hydrogels, modifications, bioactive additives and their applications in treating bone defects are presented. PMID- 30291932 TI - Fabrication of highly porous N/S doped carbon embedded with ZnS as highly efficient photocatalyst for degradation of bisphenol. AB - In the present study, a novel nanocomposite has been successfully fabricated that contain nitrogen and sulphur doped porous carbon and ZnS nanoparticles. The fabricated nanocomposite has been used as a photocatalyst for the photocatalytic degradation of bisphenol-A (BPA) under visible light. The prepared nanocomposite was characterized using FT-IR, XRD, Raman, SEM, TEM, SAED, BET and XPS. The results revealed that the fabricated nanocomposite (ZnS/NSDC) exhibited highly porosity due to large surface area 642.24 cm2/g and promising pore volumes. ZnS/NSDC nanocomposite was showed excellent photocatalytic performance for BPA degradation. During the photocatalytic degradation of BPA, several intermediate products with the molecular mass including m/z 151, m/z 133, and m/z 137 were observed using LC-MS analyses. The experimental outcomes are supported by theoretical calculations via, density functional theory (DFT) and elucidate the photocatalytic degradation mechanism of BPA. These efforts suggest that the fabricated ZnS/NSDC nanocomposite exhibits excellent properties to severe threat to environment and can be used as a reusable photocatalyst for the degradation of BPA in aqueous solution. PMID- 30291933 TI - Sulfated modification, characterization, antioxidant and hypoglycemic activities of polysaccharides from Sargassum pallidum. AB - The aim of this study was to investigate the effect of sulfated modification on the in vitro antioxidant and hypoglycemic activities of Sargassum pallidum polysaccharides (SPP). Three sulfated derivatives (S-SPP1-4, S-SPP1-6 and S-SPP1 8) were prepared using chlorosulfonic acid-pyridine method under different reaction conditions. Physicochemical characterization indicated that sulfated modification had successfully occurred. The degrees of substitution (DS) of S SPP1-4, S-SPP1-6 and S-SPP1-8 were determined to be ranging from 0.85 to 1.19. Sulfated modification resulted in some changes in chemical component, molecular weight and monosaccharide composition of SPP. Among these sulfated polysaccharides, S-SPP1-4 exhibited the best DPPH and ABTS radical scavenging activities, while S-SPP1-8 exhibited the best alpha-glucosidase inhibitory activity and promoting-effect on glucose consumption in insulin resistant (IR) HepG2 cells. Furthermore, all the sulfated derivatives exhibited better hypoglycemic ability than native SPP. These results suggest that appropriately sulfated modification could enhance the antioxidant and hypoglycemic activities of S. pallidum polysaccharides, which might be used as an alternative derivative of natural antioxidant and hypoglycemic agent. PMID- 30291934 TI - Production of levan by Bacillus licheniformis NS032 in sugar beet molasses-based medium. AB - The production of levan by Bacillus licheniformis NS032 in a medium based on sugar beet molasses was studied. High polysaccharide yields were produced by using diluted molasses (100-140 g/L of total sugars) with the addition of commercial sucrose up to 200 g/L of total sugars, as well as K2HPO4. A levan yield of 53.2 g/L was obtained on a medium optimized by response surface methodology, containing 62.6% of sugar originating from molasses, and 4.66 g/L of phosphate, with initial pH value of 7.2. In comparison to the media with 200 and 400 g/L sucrose, in the molasses optimized medium, the observed bacterial growth was faster, while the maximum production of polysaccharide was achieved over a shorter time interval (48 h). The polysaccharide produced in molasses medium had a weight average molecular weight of 5.82 * 106 Da, degree of branching 12.68%, viscosity of 0.24 dL/g, and based on methylation analysis and NMR data, it did not significantly differ from levan obtained in the medium with 200 g/L sucrose. PMID- 30291935 TI - Elongate mineral particles in the natural environment. AB - When considering elongate mineral particles (EMPs) in the natural environment it is important to first: 1) define what an elongate mineral is and 2) present what we as mineralogists and geologists know about their distribution. However, it is often very difficult to define the natural world, instead we physical scientists resort to describing it. For instance, we used 1,419 words spread over two pages of our mineralogy textbook (Dyar and Gunter, 2008) to describe a mineral. On the other hand, elongate has a rather simple non-quantitative definition as a particle longer than it is wide; however, to quantify it, we must select an aspect ratio. Cleary the term EMP was coined with the hopes to simplify some of the confusion resulting in the differing "meanings" of such words as asbestos, asbestiform, acicular, and most importantly "fiber" in the natural vs. built environment, especially when applied to amphiboles (Gunter, 2010), and non regulated asbestiform amphibole species. This paper draws on three sources: 1) the USDA-NRCS soil database (Thompson et al., 2011), 2) soil mineralogical data from USGS (Smith et al., 2013), and 3) the mineral database created in conjunction with the Dyar and Gunter (2008) textbook in an attempt to show issues created by use of the term EMP. PMID- 30291936 TI - The organophosphate pesticide methamidophos opens the blood-testis barrier and covalently binds to ZO-2 in mice. AB - Methamidophos (MET) is an organophosphate (OP) pesticide widely used in agriculture in developing countries. MET causes adverse effects in male reproductive function in humans and experimental animals, but the underlying mechanisms remain largely unknown. We explored the effect of MET on mice testes (5 mg/kg/day/4 days), finding that this pesticide opens the blood-testis barrier and perturbs spermatogenesis, generating the appearance of immature germ cells in the epididymis. In the seminiferous tubules, MET treatment changed the level of expression or modified the stage-specific localization of tight junction (TJ) proteins ZO-1, ZO-2, occludin, and claudin-3. In contrast, claudin-11 was barely altered. MET also modified the shape of claudin-11, and ZO-2 at the cell border, from a zigzag to a more linear pattern. In addition, MET diminished the expression of ZO-2 in spermatids present in seminiferous tubules, induced the phosphorylation of ZO-2 and occludin in testes and reduced the interaction between these proteins assessed by co-immunoprecipitation. MET formed covalent bonds with ZO-2 in serine, tyrosine and lysine residues. The covalent modifications formed on ZO-2 at putative phosphorylation sites might interfere with ZO-2 interaction with regulatory molecules and other TJ proteins. MET bonds formed at ZO-2 ubiquitination sites likely interfere with ZO-2 degradation and TJ sealing, based on results obtained in cultured epithelial cells transfected with ZO-2 mutated at a MET target lysine residue. Our results shed light on MET male reproductive toxicity and are important to improve regulations regarding the use of OP pesticides and to protect the health of agricultural workers. PMID- 30291937 TI - Andrographolide simultaneously augments Nrf2 antioxidant defense and facilitates autophagic flux blockade in cigarette smoke-exposed human bronchial epithelial cells. AB - Cigarette smoking is the leading cause of chronic obstructive pulmonary disease (COPD). Cigarette smoke heightens oxidative stress and impairs autophagy, advancing COPD progression. Andrographolide is a bioactive diterpenoid lactone isolated from the plant Andrographis paniculata which has been a traditional medicinal herb for respiratory diseases. As airway epithelial cells form the first interface to be exposed to cigarette smoke, this study aimed to explore the modulatory effects of andrographolide on oxidative stress and autophagy in human bronchial epithelial BEAS-2B cells exposed to cigarette smoke extract (CSE). CSE (2%) exposure increased autophagic markers p62 and LC3B-II levels in BEAS-2B cells. Andrographolide alone increased p62 and p-p62 (S349) but not LC3B-II in BEAS-2B cells. However, in the presence of CSE, andrographolide was able to simultaneously increase LC3B-II level and enhance antioxidant defense by decreasing oxidative stress and increasing total antioxidant capacity, through upregulation of nuclear Nrf2 via the p62-Nrf2 positive feedback loop. Using RFP GFP-LC3B transfected BEAS-2B cells exposed to CSE, andrographolide was found to impair autophagosome fusion with lysosome, which may account for the moderate increase in activated caspase 3/7 and annexin V levels. Our findings revealed for the first time that andrographolide simultaneously upregulated antioxidant defense through the p62-Nrf2 loop and moderately induced apoptosis through impairment of autophagic flux in CSE-exposed bronchial epithelium. Andrographolide facilitated cigarette smoke-induced apoptosis may be a potential toxicological outcome or may protect against chronic inflammation and aberrant DNA repair. Validation of these in-vitro findings in an experimental COPD model by andrographolide is warranted. PMID- 30291938 TI - Mechanisms underlying the rapid-acting antidepressant-like effects of neuropeptide VGF (non-acronymic) C-terminal peptide TLQP-62. AB - Previous studies have revealed that neuropeptide VGF (non-acronymic) C-terminal peptide TLQP-62 rapidly activates brain-derived neurotrophic factor (BDNF)/tropomyosin receptor kinase B (TrkB)/alpha-amino-3-hydroxy-5-methyl-4 isoxazolepropionic acid (AMPA) receptor/mammalian target of rapamycin (mTOR) signaling and produces antidepressant-like actions in rodents. In addition, acute TLQP-62 infusion also markedly changes the AMPA receptor GluA1 subunit phosphorylation at Ser 845 (pGluA1 Ser845) in the PFC of mice, indicating that the GluA1 may contributes to the rapid antidepressant-like effects of TLQP-62. However, how to regulate the TrkB-mediated signaling and GluA1 changes in the prefrontal cortex (PFC) by TLQP-62 remains unclear. Herein, acute administration of TLQP-62 into PFC produced rapid-acting antidepressant-like effects in mice. Additionally, we confirmed that TLQP-62 ameliorated the depression-like behaviors induced by chronic social defeat stress (CSDS) in mice. Further investigation demonstrated that this effect of TLQP-62 was mediated by activation of TrkB and mTOR, which proceeded to decrease bicaudal C homolog 1 gene (BICC1) and increase synaptic protein expression, including GluA1 subunit and pGluA1 Ser845. Notably, we further found that beneficial effects of TLQP-62 on depression-like behaviors and TrkB/mTOR/BICC1 signaling, GluA1 phosphorylation and GluA1 activation in the PFC of mice were significantly abolished by TrkB antagonist ANA-12. In conclusion, our findings indicate that TrkB/mTOR/BICC1 signaling, GluA1 phosphorylation and GluA1 activation in the PFC may involve in the rapid-acting antidepressant-like actions of TLQP-62 in mice. PMID- 30291939 TI - Dexpramipexole enhances hippocampal synaptic plasticity and memory in the rat. AB - Even though pharmacological approaches able to counteract age-dependent cognitive impairment have been highly investigated, drugs improving cognition and memory are still an unmet need. It has been hypothesized that sustaining energy dynamics within the aged hippocampus can boost memory storage by sustaining synaptic functioning and long term potentiation (LTP). Dexpramipexole (DEX) is the first in-class compound able to sustain neuronal bioenergetics by interacting with mitochondrial F1Fo-ATP synthase. In the present study, for the first time we evaluated the effects of DEX on synaptic fatigue, LTP induction, learning and memory retention. We report that DEX improved LTP maintenance in CA1 neurons of acute hippocampal slices from aged but not young rats. However, we found no evidence that DEX counteracted two classic parameters of synaptic fatigue such as fEPSP reduction or the train area during the high frequency stimulation adopted to induce LTP. Interestingly, patch-clamp recordings in rat hippocampal neurons revealed that DEX dose-dependently inhibited (IC50 814 nM) the IA current, a rapidly-inactivating K+ current that negatively regulates neuronal excitability as well as cognition and memory processes. In keeping with this, DEX counteracted both scopolamine-induced spatial memory loss in rats challenged in Morris Water Maze test and memory retention in rats undergoing Novel Object Recognition. Overall, the present study discloses the ability of DEX to boost hippocampal synaptic plasticity, learning and memory. In light of the good safety profile of DEX in humans, our findings may have a realistic translational potential to treatment of cognitive disorders. PMID- 30291941 TI - ASIC1a promotes high glucose and PDGF-induced hepatic stellate cell activation by inducing autophagy through CaMKKbeta/ERK signaling pathway. AB - It is well known that the diabetes mellitus complicates liver fibrosis with high morbidity, and Acid-sensing ion Channel 1a (ASIC1a) plays an important role in the development of diabetes and liver fibrosis. However, the underlying mechanism about how diabetes influences the progression of liver fibrosis remains unclear. This study was to investigate the relationship between autophagy and ASIC1a in the process of liver fibrosis under hyperglycemia. Interestingly, our study showed that the autophagy was elevated in the livers from diabetes combined with liver fibrosis double model in vivo and also in rat hepatic stellate cell line HSC-T6 after stimulation with high glucose and platelet-derived growth factor (PDGF) in vitro, and this response could be attenuated by treatment with ASIC1a nonspecific inhibitor Amiloride or specific ShRNA for ASIC1a. Furthermore, inhibition of autophagy treated with 3-MA significantly attenuated HSC-T6 activation and proliferation. Mechanistically, CaMKKbeta/ERK pathway was activated in HSC-T6 after stimulation with high glucose and PDGF, and could be suppressed by Amiloride. Collectively, we concluded that autophagy induced by ASIC1a contributes to HSC-T6 activation, which ing pathway. PMID- 30291940 TI - Effects of acute Delta9-tetrahydrocannabinol on next-day extinction recall is mediated by post-extinction resting-state brain dynamics. AB - We have previously demonstrated that an acute dose of Delta9 tetrahydrocanninbinol (THC), administered prior to extinction learning, facilitates later recall of extinction learning and modulates the underlying neural circuitry, including the ventromedial prefrontal cortex (vmPFC), hippocampus (HPC), and amygdala (AMYG). It remains unknown whether THC-induced changes in fear-extinction neural circuitry can be detected following extinction learning, which may reflect ongoing processes involved consolidation of the extinction memory. To address this gap, we used a randomized, double-blind, placebo-controlled, between-subjects design to compare acute pharmacological effects of THC (7.5 mg) vs. placebo (PBO) on post-extinction resting-state functional connectivity (RS-FC) within fear-extinction circuitry in 77 healthy adults (THC = 40; PBO = 37). RS-FC was examined between vmPFC, HPC, and AMYG using two complementary approaches: 1) static RS-FC (average correlation in ROI ROI pairs across the entire scan); and 2) dynamic (i.e., time-varying) RS-FC (sliding window correlation time series' variance). RS-FC was then linked to behavioral and brain measures of extinction recall. Compared to PBO, THC administration was associated with lower AMYG-HPC static RS-FC, but higher AMYG vmPFC dynamic RS-FC. Lower AMYG-HPC static RS-FC was associated with higher HPC activation, as well as, better extinction recall. Moreover, lower AMYG-HPC static RS-FC following extinction learning mediated the link between THC administration and extinction recall. Post-extinction RS-FC patterns may reflect sustained effects of THC on fear-extinction circuitry even in the absence of an overt task, and/or effects of ongoing processes that serve to strengthen the neural connections supporting the consolidation of the memory and better extinction recall.

PMID- 30291943 TI - Phytochemical analysis and anti-inflammatory effects of Filipendula vulgaris Moench extracts. AB - Filipendula vulgaris Moench (dropwort) is used in traditional medicine for relieving various inflammation-related diseases. In the present study, the phytochemical profile of F. vulgaris aerial part (FVA) and root (FVR) methanolic extracts was evaluated by LC-DAD-HRMS analysis. Furthermore, their in vitro and in vivo anti-inflammatory effects, as well as their potential cytotoxicity, were assessed. Results showed that the extracts mainly contain phenolics like flavonoids, hydrolyzable tannins, procyanidins, and phenolic acid derivatives, including gaultherin. No in vitro cytotoxicity was found at the highest concentration (50 MUg/mL). FVA extract (50 MUg/mL) significantly inhibited cyclooxygenase-1 and -2 (COX-1 and COX-2) activities in vitro (>50% inhibition), and FVR extract considerably inhibited COX-2 activity (52.5 +/- 2.7%) without affecting COX-2 gene expression in LPS-stimulated THP-1 cells. The extracts demonstrated prominent in vivo anti-inflammatory potential upon oral administration in rats. Especially FVA extract at 100 and 200 mg/kg significantly inhibited carrageenan-induced edema formation. From these results, it can be concluded that F. vulgaris extracts possess interesting anti-inflammatory properties. PMID- 30291944 TI - Coffee, caffeine, chlorogenic acid, and the purinergic system. AB - Coffee is a drink prepared from roasted coffee beans and is lauded for its aroma and flavour. It is the third most popular beverage in the world. This beverage is known by its stimulant effect associated with the presence of methylxanthines. Caffeine, a purine-like molecule (1,3,7 trymetylxantine), is the most important bioactive compound in coffee, among others such as chlorogenic acid (CGA), diterpenes, and trigonelline. CGA is a phenolic acid with biological properties as antioxidant, anti-inflammatory, neuroprotector, hypolipidemic, and hypoglicemic. Purinergic system plays a key role inneuromodulation and homeostasis. Extracellular ATP, other nucleotides and adenosine are signalling molecules that act through their specific receptors, namely purinoceptors, P1 for nucleosides and P2 for nucleotides. They regulate many pathological processes, since adenosine, for instance, can limit the damage caused by ATP in the excitotoxicity from the neuronal cells. The primary purpose of this review is to discuss the effects of coffee, caffeine, and CGA on the purinergic system. This review focuses on the relationship/interplay between coffee, caffeine, CGA, and adenosine, and their effects on ectonucleotidases activities as well as on the modulation of P1 and P2 receptors from central nervous system and also in peripheral tissue. PMID- 30291945 TI - Renal toxicity through AhR, PXR, and Nrf2 signaling pathway activation of ochratoxin A-induced oxidative stress in kidney cells. AB - Because ochratoxin A (OTA) is widely found in foods, people are susceptible to OTA exposure. The mechanism leading to renal toxicity induced by OTA remains unclear. The aim of this study was to investigate OTA-induced toxicity in human proximal tubule HK-2 cells. OTA decreased cell viability, and the expression of kidney injury molecule-1 (KIM-1), a kidney damage marker, was increased when HK-2 cells were exposed to OTA. Additionally, OTA treatment of cells increased intracellular reactive oxygen species and malondialdehyde and decreased glutathione levels. OTA-treated cells induced the aryl hydrocarbon receptor (AhR) and pregnane X receptor (PXR) genes followed by induction of the cytochrome P450 1A1 (CYP1A1), CYP1A2, and CYP3A4 genes representing phase I enzyme. The mRNA expression of phase II enzymes such as heme oxygenase-1, nicotinamide adenine dinucleotide phosphate-quinone oxidoreductase 1, and glutamate cysteine ligase catalytic subunit were upregulated by activation of NF-E2-related factor 2 (Nrf2) translocation by treatment with OTA. The response of OTA-orally administered mice also showed marked increases in these enzymes as well as KIM-1. These results indicate that OTA induces phase I and II enzymes through the AhR, PXR, and Nrf2 signaling pathways in HK-2 cells, which may lead to modulation of proximal tubule injury. PMID- 30291946 TI - Targeting thioredoxin glutathione reductase as a potential antischistosomal drug target. AB - Schistosomiasis represents a world health major problem affecting more than 206 million people worldwide. Up to date, praziquantel (PZQ) is the sole chemotherapeutic agent used in clinics for the treatment of schistosomiasis. The resistance to PZQ chemotherapy that has been emerged against some schistosome phenotypes represents the most serious PZQ-related problem so far. Therefore, it is clear that there is a substantial need to develop novel and effective antischistosomal agents in order to ensure the effective drug control of schistosomiasis in the future. It is well-documented that the thiol redox homeostasis of schistosomes is entirely based on a single enzyme named thioredoxin-glutathione reductase (TGR). Thus, TGR is an essential protein for the survival of schistosomes which means that TGR is a valid and promising target for the recent antischistosomal drug-discovery approaches. This review aimed to shed light on potential lead compounds that may inhibit TGR activity and consequently could be tested as a potential antischistsomal drugs. In the current review we discussed multiple drug discovery approaches for new compounds targeting TGR and its implementation. PMID- 30291947 TI - Loss of cAMP-dependent stimulation of isolated cilia motility by alcohol exposure is oxidant dependent. AB - Alcohol exposure is associated with decreased mucociliary clearance, a key innate defense essential to lung immunity. Previously we identified that prolonged alcohol exposure results in dysfunction of airway cilia that persists at the organelle level. This dysfunction is characterized by a loss of 3',5'-cyclic adenosine monophosphate (cAMP)-mediated cilia stimulation. However, whether or not ciliary dysfunction develops intrinsically at the organelle level has not been explored. We hypothesized that prolonged alcohol exposure directly to isolated demembranated cilia (axonemes) causes ciliary dysfunction. To test this hypothesis, we exposed isolated axonemes to alcohol (100 mM) for 1-24 h and assessed ciliary beat frequency (CBF) in response to cAMP at 1, 3, 4, 6 and 24 h post exposure. We found that after 1 h of alcohol exposure cilia axonemes do not increase CBF in response to cAMP. Importantly, by 6 h after the initial exposure to alcohol, cAMP-mediated CBF was restored to control levels. Additionally, we found that thioredoxin reverses ciliary dysfunction in axonemes exposed to alcohol. Finally, we identified, using a combination of a xanthine oxidase oxidant-generating system, direct application of hydrogen peroxide, and electron paramagnetic resonance, that hydrogen peroxide versus superoxide, is likely the key oxidant species driving alcohol-induced ciliary dysfunction in isolated axonemes. These data highlight the role of alcohol to stimulate local production of oxidants in the axoneme to cause ciliary dysfunction. Additionally, these data specifically add hydrogen peroxide as a potential therapeutic target in the treatment or prevention of alcohol-associated ciliary dysfunction and subsequent pneumonia. PMID- 30291948 TI - An association between MMP-9 and impaired T cell migration in ethanol-fed BALB/c mice infected with Respiratory Syncytial Virus-2A. AB - Matrix metalloproteinases are important for proper airway matrix structure and wound healing. These enzymes are also implicated in many airway diseases. Previously, chronic ethanol consumption was shown to prolong inflammation and delay viral clearance in respiratory syncytial virus (RSV)-infected mice. We hypothesize that alcohol alters anti-viral immunity by disrupting immune cell chemotaxis in the lung. BALB/c mice were randomly selected to consume 18% alcohol ad libitum for 8 weeks prior to infection with RSV-2A. Bronchoalveolar lavage (BAL) cell populations were measured by flow cytometry and chemokines detected by Western blot or ELISA. MMP-9 levels were determined by polymerase chain reaction (PCR) in mouse lungs and in BAL fluid by ELISA. T cells were acquired from the spleens of water-fed, non-infected control mice (CTRL); alcohol-fed, non-infected (ETOH); water-fed, RSV-infected (RSV); or ethanol-fed, RSV-infected (ETOH-RSV) 4 days after RSV infection. T cells were placed in a transmigration system where chemokines had been treated with and without activated MMP-9. Lymphocyte recruitment was significantly reduced in the BAL 4 days after RSV infection in ETOH-RSV mice, whereas chemokine levels were the highest in this group at all experimental time points examined in comparison to RSV (P< 0.05). MMP-9 mRNA and protein were detected at high levels in ETOH-RSV mice compared to RSV. Using ex vivo transmigration to CCL2 and CXCL10, T cell migration was not impaired between any of the treatment groups, yet when CCL2 and CXCL10 were treated with activated MMP-9, significantly fewer T cells migrated across collagen-coated 5MUm membranes (P < 0.05). Immune cell recruitment is necessary for viral clearance. We show that immune cells are decreased in the lungs of ETOH-RSV mice. In contrast to decreased cell recruitment, key inflammatory chemokines were elevated in the lungs of ETOH-RSV mice. These proteins may be prematurely degraded by MMP-9 in the lung, leading to defective immunity and reduced viral clearance. PMID- 30291949 TI - Control and Context Are Central for People With Advanced Illness Experiencing Breathlessness: A Systematic Review and Thematic Synthesis. AB - CONTEXT: Breathlessness is common and distressing in advanced illness. It is a challenge to assess, with few effective treatment options. To evaluate new treatments, appropriate outcome measures that reflect the concerns of people experiencing breathlessness are needed. OBJECTIVES: The objective of this study was to systematically review and synthesize the main concerns of people with advanced illness experiencing breathlessness to guide comprehensive clinical assessment and inform future outcome measurement in clinical practice and research. METHODS: This is a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology. MEDLINE (1946-2017), PsycINFO (1806-2017), and EMBASE (1974-2017), as well as key journals, gray literature, reference lists, and citation searches, identified qualitative studies exploring the concerns of people living with breathlessness. Included studies were quality-assessed using the Critical Appraisal Skills Program checklist and analyzed using thematic synthesis. RESULTS: We included 38 studies with 672 participants. Concerns were identified across six domains of "total" breathlessness: physical, emotional, spiritual, social, control, and context (chronic and episodic breathlessness). Four of these have been previously identified in the concept of "total dyspnea." Control and context have been newly identified as important, particularly in their influence on coping and help seeking behavior. The importance of social participation, impact on relationships, and loss of perceived role within social and spiritual domains also emerged as being significant to individuals. CONCLUSION: People with advanced illness living with breathlessness have concerns in multiple domains, supporting a concept of "total breathlessness." This adapted model can help to guide comprehensive clinical assessment and inform future outcome measurement in clinical practice and research.

PMID- 30291951 TI - Introduction of bifunctional alcohol/acetaldehyde dehydrogenase gene (adhE) in Fructobacillus fructosus settled its fructophilic characteristics. AB - Fructophilic lactic acid bacteria (FLAB) are unique in the sense that they prefer D-fructose over D-glucose as main carbon source. If D-glucose is metabolised, electron acceptors are required and significant levels of acetate are produced. These bacteria are found in environments rich in D-fructose, such as flowers, fruits and the gastrointestinal tract of insects feeding on fructose-rich diets. Fructobacillus spp. are representatives of this unique group, and their fructophilic characteristics are well conserved. In this study, the bifunctional alcohol/acetaldehyde dehydrogenase gene (adhE) from Leuconostoc mesenteroides NRIC 1541T was cloned into a plasmid and transferred to Fructobacillus fructosus NRIC 1058T. Differences in biochemical characteristics between the parental strain (NRIC 1058T) and the transformants were compared. Strain 1-11, transformed with the adhE gene, did not show any fructophilic characteristics, and the strain grew well on D-glucose without external electron acceptors. Accumulation of acetic acid, which was originally seen in the parental strain, was replaced with ethanol in the transformed strain. Furthermore, in silico analyses revealed that strain NRIC 1058T lacked the sugar transporters/permeases and enzymes required for conversion of metabolic intermediates. This may be the reason for poor carbohydrate metabolic properties recorded for FLAB.

PMID- 30291954 TI - The effect of age, sex and strains on the performance and outcome in animal models of stroke. AB - Stroke is one of the leading causes of death worldwide, and the majority of cerebral stroke is caused by occlusion of cerebral circulation, which eventually leads to brain infarction. Although stroke occurs mainly in the aged population, most animal models for experimental stroke in vivo almost universally rely on young-adult rodents for the evaluation of neuropathological, neurological, or behavioral outcomes after stroke due to their greater availability, lower cost, and fewer health problems. However, it is well established that aged animals differ from young animals in terms of physiology, neurochemistry, and behavior. Stroke-induced changes are more pronounced with advancing age. Therefore, the overlooked role of age in animal models of stroke could have an impact on data quality and hinder the translation of rodent models to humans. In addition to aging, other factors also influence functional performance after ischemic stroke. In this article, we summarize the differences between young and aged animals, the impact of age, sex and animal strains on performance and outcome in animal models of stroke and emphasize age as a key factor in preclinical stroke studies. PMID- 30291953 TI - Tyrosol attenuates pro-inflammatory cytokines from cultured astrocytes and NF kappaB activation in in vitro oxygen glucose deprivation. AB - Subsequent inflammation in stroke plays an important role in the damage of neurons in the perilesional area. Therapeutic intervention targeting inflammation may be a promising complementary strategy to current treatments of stroke. Here, we explored the possible beneficial effects of tyrosol, a derivative of phenethyl alcohol and natural antioxidant, playing an anti-inflammatory role in astrocyte culture and in vitro oxygen glucose deprivation (OGD) model. MTT, western blot, ELISA and EMSA assays were carried out to investigate cell viability, protein expression level, cytokine expression and NF-kappaB activity. We found tyrosol protected cultured astrocytes against OGD-induced cell viability loss in MTT test. Meanwhile, tyrosol attenuated the released TNF-alpha and IL-6 level from astrocyte via regulating Janus N-terminal kinase (JNK). The reduction of cytokines from astrocyte might be due to its inhibition of astrocyte activation and regulation of STAT3 signaling pathway since tyrosol attenuated the expression level of GFAP (glial fibrillary acidic protein) and the phosphorylation of STAT3. Additionally, we demonstrated that tyrosol prevented the degradation of IkappaBalpha and the increase of IkappaBalpha phosphorylation in astrocytes exposed to OGD, which led to the suppression of NF-kappaB function during ischemia. Collectively, our results showed that tyrosol may be a promising complementary treatment compound for stroke via modulating the inflammatory response in astrocytes during ischemia. PMID- 30291956 TI - Uncaria rhynchophylla ameliorates amyloid beta deposition and amyloid beta mediated pathology in 5XFAD mice. AB - One of the pathological hallmarks of Alzheimer's disease (AD) is the abnormal aggregation of amyloid beta (Abeta) peptides. Uncaria rhynchophylla (UR), one of the Uncaria species, has long been used to treat neurodegenerative disease. In particular, it has been reported that UR inhibits aggregation of Abeta in vitro. However, little is known about the histological effects of UR treatment on Abeta pathology in AD animal models. In the present study, we investigated the effect of UR on Abeta aggregation, Abeta-mediated pathologies and adult hippocampal neurogenesis in the brain of 5XFAD mice. First, using the thioflavin T assay and amyloid staining, we demonstrated that UR treatment effectively inhibited Abeta aggregation and accumulation in the cortex and subiculum. Second, immunofluorescence staining showed that administration of UR attenuated gliosis and neurodegeneration in the subiculum and cortex. Third, UR treatment ameliorated impaired adult hippocampal neurogenesis. The present results indicate that UR significantly alleviates Abeta deposition and Abeta-mediated neuropathology in the brain in 5XFAD mice, suggesting the potency of UR as a preventive and therapeutic agent for AD. PMID- 30291957 TI - A Poloxamer-407 modified liposome encapsulating epigallocatechin-3-gallate in the presence of magnesium: Characterization and protective effect against oxidative damage. AB - Epigallocatechin-3-gallate (EGCG) is a polyphenolic catechin from green tea, well known for being bioactive in age-associated pathologies where oxidative stress plays a preeminent role. The activity of this molecule is however contrasted by its high chemical and metabolic instability that determines a poor concentration of the antioxidant within the biological system after administration. In order to protect the molecule and increase its delivery efficiency, we have encapsulated EGCG inside anionic liposomes made of 1-palmitoyl-2-oleoyl-sn-glycero-3 phosphocholine, 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine and cholesteryl hemisuccinate. To maximize EGCG internalization, magnesium salt was added in the preparation. However stable nanodispersions suitable for drug delivery were obtained only after treatment with Poloxamer-407, a polyethylene-propylene glycol copolymer. The structural and morphological properties of the produced dispersion were studied by X-ray diffraction, which showed a multilamellar structure even after EGCG addition and an ordering effect of Poloxamer-407; Dynamic Light Scattering demonstrated serum stability of the liposomes. The characterization was completed by evaluating both encapsulation efficiency (100%, in the final formulation) and in vitro EGCG release. Since oxidative stress is involved in numerous retinal degenerative diseases, such as age-related macular degeneration, the ability of these liposomes to contrast H2O2-induced cell death was assessed in human retinal cells. Morphological changes at the subcellular level were analyzed by Transmission Electron Microscopy, which showed that mitochondria were better preserved in cells treated with liposomes then those treated with free EGCG. In conclusion, the results demonstrated that the produced formulation enhances the efficacy of EGCG under stress conditions, thus representing a potential formulation for the intracellular delivery of EGCG in diseases caused by oxidative damage. PMID- 30291958 TI - Prevention of rat liver fibrosis by selective targeting of hepatic stellate cells using hesperidin carriers. AB - Therapeutic efficacy of antifibrotic drugs can be improved by targeting hepatic stellate cells (HSCs). This study investigated the prospect of developing a carrier system for the effective delivery of hesperidin by selectively targeting HSCs in fibrotic rat model. Hesperidin-loaded surface modified liposome formulations were prepared with varying quantity of lipids to optimize physicochemical characteristics. Best liposome formulation was further conjugated with a homing ligand, recognized by HSCs, to achieve a carrier system that facilitates the targeting of hesperidin. This carrier system was characterized for various physicochemical properties. The effectiveness of the bioactive carrier to prevent liver fibrosis was investigated by carrying out biochemical, biodistribution, and histopathological analyses. The pharmaceutical properties demonstrated by the ligand conjugated carrier system were optimal to facilitate selective and preferential delivery to the liver. Steady and prolonged drug release behavior with zero order kinetics displayed by prepared carrier system established its prospect to increase efficiency and decrease dosing of hesperidin. The pharmacokinetic profile of the carrier system was very distinct and exhibited rapid plasma clearance. The bio-distribution data of formulated carrier system indicates higher uptake of hesperidin predominantly by fibrotic liver with insignificant amount in non-targeted organs, which is certainly beneficial due to low risk of toxicity and lower systemic distribution. In conclusion, this developed carrier represents a potentially beneficial approach for HSCs specific targeting of hesperidin in a rat model with liver fibrosis. PMID- 30291959 TI - Novel ultra-small micelles based on rebaudioside A: A potential nanoplatform for ocular drug delivery. AB - We investigated if the self-assembled micelles of rebaudioside A (RA) could potentially be utilized as an ocular drug-delivery system in this investigation. RA self-assembled into micelles with ultra-small particle sizes (<4 nm) in a homogeneous distribution state (polydispersity index < 0.3). RA had good cellular tolerance and no cytotoxicity was observed at concentrations <= 18.5 mg/ml at 72 h of incubation. RA also did not cause cell apoptosis at concentration <= 12 mg/ml. Coumarin-6 (Cou6)-loaded RA micelles had good cellular tolerance and in vivo non-irritants to the rabbit eyes. RA micelles dramatically improved the cellular uptake of Cou6 (compared to free-Cou6 P < 0.05); an energy-independent, active, intracellular endocytosis pathway was apparently involved, and cellular organelles such as lysosomes, endoplasmic reticuli, and mitochondria were observed with a high distribution of Cou6, while a much more sophisticated endocytosis pathway was apparently involved in the ex vivo corneal endocytosis mechanism tests. The use of RA micelles significantly improved in vivo corneal permeation of the encapsulated Cou6 when compared to free-Cou6 eye drops (P < 0.05). These findings indicate that RA micelle formulations have great potential as a novel ocular drug-delivery system to improve the bioavailability of hydrophobic drugs. PMID- 30291960 TI - A novel antibacterial agent based on AgNPs and Fe3O4 loaded chitin microspheres with peroxidase-like activity for synergistic antibacterial activity and wound healing. AB - In this study, a novel antibacterial agent was developed based on chitin nanofibrous microspheres loaded with AgNPs and Fe3O4 nanoparticles (Ag-Fe3O4-NMs) for synergistic antibacterial activity and wound healing. Ag-Fe3O4-NMs was prepared via an in situ synthetic method which showed an excellent porosity and wettability. Moreover, Ag-Fe3O4-NMs were capable of sustained release of Ag+ and catalysed the decomposition of low H2O2 concentrations to generate hydroxyl radical (OH). The OH and Ag+ showed higher antibacterial activity and inhibited the toxicity with high dose of AgNPs and H2O2. In vitro biocompatibility results suggested that Ag-Fe3O4-NMs have low toxicity and low hemolysis. Thus, a novel antibacterial agent with enhanced synergistic antibacterial activity was obtained by combination of Ag-Fe3O4-NMs and H2O2 at a low and biologlically safe dosage, which could facilitate fibroblast growth, accelerate epithelialization, and promote the healing rate of infected wounds. PMID- 30291961 TI - Smart pH responsive drug delivery system based on poly(HEMA-co-DMAEMA) nanohydrogel. AB - The advent of smart nanohydrogel has revealed new opportunities for scientists to develop the most efficient anti-cancer vehicles with safe and biocompatible profile. In this experiment, using reversible addition-fragmentation chain transfer polymerization method as a novel, safe and smart pH responsive formulation of poly (hydroxyethyl methacrylate-co-N,N-dimethylaminoethyl methacrylate) and poly (ethylene glycol)-diacrylate as cross-linker were synthesized. The synthesized structure was confirmed by Fourier-transform infrared spectroscopy and proton nuclear magnetic resonance methods. The pH responsive behavior of the synthesized particles was checked by size measurement in two different pH values (5.5 and 7.4) by dynamic light scattering and transmission electron microscopy. The prepared structure had nanometer sizes of 180 in medium with pH of 7.4, when it encountered acidic medium (e.g. pH 5.5), the particles swelled to about 400 nm. The efficiency of the prepared pH responsive nanohydrogels was tested as a drug delivery system. An anti-cancer drug, doxorubicin successfully interacted with this material. The release profiles of nanoparticles carrying drug molecules were checked in two different simulated pH of healthy organs (7.4) and tumor site (5.5). Despite lower release in pH of 7.4 (~20%), an increased drug release of 80% was obtained in pH of 5.5. The in vitro toxicity assay, apoptosis evaluation and uptake experiments were performed on breast cancer cell line (MCF-7), which showed a time dependency cellular entrance, an enhanced cytotoxicity and apoptosis induction by the doxorubicin loaded nanoparticles. Hemolysis assays confirmed the safety and hemocompatibility of the developed nanohydrogel. The suitable size (<200 nm), pH responsive behavior, anti-proliferative activity and apoptosis induction in cancer cells and hemocompatibility were the noticeable features of the developed doxorubicin adsorbed nanoparticle, which introduced this formulation as an ideal vehicle in anti-cancer drug delivery. PMID- 30291962 TI - A 5-lipoxygenase-specific sequence motif impedes enzyme activity and confers dependence on a partner protein. AB - Leukotrienes (LT) are lipid mediators of the inflammatory response that play key roles in diseases such as asthma and atherosclerosis. The precursor leukotriene A4 (LTA4) is synthesized from arachidonic acid (AA) by 5-lipoxygenase (5-LOX), a membrane-associated enzyme, with the help of 5-lipoxygenase-activating protein (FLAP), a nuclear transmembrane protein. In lipoxygenases the main chain carboxylate of the C-terminus is a ligand for the non-heme iron and thus part of the catalytic center. We investigated the role of a lysine-rich sequence (KKK653 655) 20 amino acids upstream of the C-terminus unique to 5-LOX that might displace the main-chain carboxylate in the iron coordination sphere. A 5-LOX mutant in which KKK653-655 is replaced by ENL was transfected into HEK293 cells in the absence and presence of FLAP. This mutant gave ~20-fold higher 5-LOX product levels in stimulated HEK cells relative to the wild-type 5-LOX. Co expression of the enzymes with FLAP led to an equalization of 5-LOX products detected, with wild-type 5-LOX product levels increased and those from the mutant enzyme decreased. These data suggest that the KKK motif limits 5-LOX activity and that this attenuated activity must be compensated by the presence of FLAP as a partner protein for effective LT biosynthesis.

AB - This study focussed on investigating the coupling of continuous manufacturing of drug substance and continuous manufacture of drug product. An important step in such an integrated end-to-end continuous manufacturing was envisioned by dosing the API as suspension into a twin-screw wet granulation process. To achieve this goal, a model drug substance (ibuprofen) was fed as a concentrated aqueous suspension (50% w/w) into a twin-screw granulator and compared against traditional solid feeding of the model drug substance to meet a target ibuprofen load of 60% w/w in the formulation. Granulation and compaction behaviour were evaluated to determine the impact of feeding API as suspension in twin-screw wet granulation on the critical quality attributes of the drug product. It was demonstrated that the ibuprofen suspension feed is comparable with the ibuprofen dry blend feed in twin-screw wet granulation. Next to enabling end-to-end continuous manufacturing, API suspension feed in twin-screw wet granulation could afford a number of additional advantages including manufacturing efficiency by removing the drying step for API, or overcoming processing issues linked to the bulk properties of the API powder (e.g. flowability).

AB - Inflammation processes are associated with significant decreases in tissue or lysosomal pH from 7.4 to 4, a fact that argues for the application of pH responsive drug delivery systems. However, for their design and optimization a full understanding of the release mechanism is crucial. In this study we investigated the pH-depending drug release mechanism and the influence of silk fibroin (SF) concentration and SF degradation degree of human serum albumin (HSA) SF nanocapsules. Sonochemically produced nanocapsules were investigated regarding particle size, colloidal stability, protein encapsulation, thermal stability and drug loading properties. Particles of the monodisperse phase showed average hydrodynamic radii between 438 and 888 nm as measured by DLS and AFM and a zeta potential of -11.12 +/- 3.27 mV. Together with DSC results this indicated the successful production of stable nanocapsules. ATR-FTIR analysis demonstrated that SF had a positive effect on particle formation and stability due to induced beta sheet formation and enhanced crosslinking. The pH-responsive release was found to depend on the SF concentration. In in-vitro release studies, HSA-SF nanocapsules composed of 50% SF showed an increased pH-responsive release for all tested model substances (Rhodamine B, Crystal Violet and Evans Blue) and methotrexate at the lowered pH of 4.5 to pH 5.4, while HSA capsules without SF did not show any pH responsive drug release. Mechanistic studies using confocal laser scanning microscopy (CLSM) and small angle X-ray scattering (SAXS) analyses showed that increases in particle porosity and decreases in particle densities are directly linked to pH-responsive release properties. Therefore, the pH-responsive release mechanism was identified as diffusion controlled in a novel and unique approach by linking scattering results with in-vitro studies. Finally, cytotoxicity studies using the human monocytic THP-1 cell line indicated non-toxic behavior of the drug loaded nanocapsules when applied in a concentration of 62.5 ug mL-1. Based on the obtained release properties of HSA-SF nanocapsules formulations and the results of in-vitro MTT assays, formulations containing 50% SF showed the highest requirements arguing for future in vivo experiments and application in the treatment of inflammatory diseases.

AB - Phytochemical study on the roots and rhizomes of Notopterygium incisum resulted in the isolation of six new coumarins, notoptetherins A - F (1-6), and 20 known analogues (7-26). Their structures were elucidated on the basis of extensive analyses of NMR and HRMS data, and the absolute configurations of 5 and 6 were established by Mo2(AcO)4-induced CD and exciton chirality, respectively. Moreover, a biomimetic synthesis of 6 from 21 was employed to confirm its absolute configuration. In a subsequent activity screening, compounds 12 and 17 exhibited potent inhibition against LPS-induced nitric oxide production in RAW 264.7 cells with IC50 values of 12.7 and 10.2 MUM, respectively. PMID- 30291966 TI - A pharmacokinetic study on oleracone C after oral and intravenous administration. AB - Oleracone C, a new homoisoflavanone recently isolated from the plant Portulaca oleracea L., has obvious pharmacological activities. Subsequently, its pharmacokinetic profiles in rats' plasma after oral and intravenous administrations were studied by a simple and rapid ultra high-performance liquid chromatography electrospray ionization quadrupole-time of flight mass spectrometry (UHPLC-ESI-Q-TOF/MS) with apigenin as an internal standard (IS). The analysis was performed on an Agilent Zorbax Eclipse Plus C18 Column (2.1 * 50 mm, 1.8 MUm) by elution with acetonitrile and water (containing 0.1% formic acid) at a flow rate of 0.3 mL/min. Electrospray ionization in negative ion mode was used to quantify oleracone C and apigenin, with monitored ion m/z values of 299.0915 [M - H]- and 269.0455 [M - H]-. The linear range was established over the concentration range 10-2000 ng/mL (r = 0.9971). The limit of detection (LOD) and limit of quantification (LOQ) were 3 and 10 ng/mL for oleracone C, respectively. The RSD and RE of intra- and inter- day accuracy and precision were all less than 15%. The pharmacokinetic results indicated that oleracone C was rapidly distributed with the time to peak concentrations of 0.03 h and 0.33 h, respectively after intravenous and oral administrations and presented a low absolute bioavailability of 8.32%. This is the first study to successfully examine the pharmacokinetics of homoisoflavanone in rats' plasma after oral and intravenous administrations, using rapid, sensitive and specific UHPLC-ESI-Q TOF/MS method. PMID- 30291967 TI - New antimicrobial compounds produced by endophytic Penicillium janthinellum isolated from Panax notoginseng as potential inhibitors of FtsZ. AB - A total of 180 fungal isolates, belonging to 20 genera and 47 species, were obtained from the roots, stems and leaves of Panax notoginseng. One isolate, the endophytic fungus Penicillium janthinellum SYPF 7899, displayed the strongest antibacterial activity and was studied for its production of secondary metabolites. In total, three new compounds, including rotational isomers 1a, 1b and 2 were isolated from the solid cultures of P. janthinellum, as well as eight known compounds (3-10). These structures were determined on the basis of 1D, 2D NMR and electronic circular dichroism (ECD) spectroscopic analyses as well as theoretical calculations. Compound 1 exhibited significant inhibitory activities against Bacillus subtilis and Staphylococcus aureus with MIC values of 15 and 18 MUg/ml, respectively. The other compounds showed moderate or weak activities. In addition, morphological observation showed the rod-shaped cells of B. subtilis growing into long filaments, which reached 1.5- to 2-fold of the length of the original cells after treatment with compound 1. The coccoid cells of S. aureus exhibited a similar response and swelled to a 2-fold volume after treatment with compound 1. In silico molecular docking was explored to study the binding interactions between the compounds and the active sites of filamentous temperature-sensitive protein Z (FtsZ) from B. subtilis and S. aureus. Compound 1a, 1b and 2 showed high binding energies, strong H-bond interactions and hydrophobic interactions with FtsZ. Based on the antimicrobial activities, cellular phenotype observation and docking studies, compound 1 is considered to be a promising antimicrobial inhibitor of FtsZ.

AB - Tomato mosaic virus (ToMV; genus, Tobamovirus) is a member of the alpha-like virus superfamily of positive-strand RNA viruses, which includes many plant and animal viruses of agronomical and clinical importance. The genomes of alpha-like viruses encode replication-associated proteins that contain methyltransferase, helicase and/or polymerase domains. The three-dimensional structure of the helicase domain fragment of ToMV has been determined, but the structures of the other domains of alpha-like virus replication proteins are not available. In this study, we expressed full-length ToMV replication-associated protein 130 K, which contains the methyltransferase and helicase domains, using the baculovirus silkworm expression system and purified the recombinant protein to near homogeneity. Purified 130 K, which was stable in phosphate buffer containing magnesium ions and ATP, formed a dimer in solution and hydrolyzed nucleoside 5' triphosphates. PMID- 30291969 TI - Improving access to psychological therapies (IAPT) for people with bipolar disorder: Summary of outcomes from the IAPT demonstration site. AB - Access to structured psychological therapy recommended for bipolar disorder (BD) is poor. The UK NHS Improving Access to Psychological Therapies initiative commissioned a demonstration site for BD to explore the outcomes of routine delivery of psychological therapy in clinical practice, which this report summarises. All clinically diagnosed patients with BD who wanted a psychological intervention and were not in acute mood episode were eligible. Patients were offered a 10-session group intervention (Mood on Track) which delivered NICE congruent care. Outcomes were evaluated using an open (uncontrolled), pre-post design. Access to psychological therapy increased compared to preceding 6 years by 54%. 202 people began treatment; 81% completed >5 sessions; median 9 sessions (range 6-11). Pre-post outcomes included personal recovery (primary outcome), quality of life, work and social functioning, mood and anxiety symptoms (secondary outcomes). Personal recovery significantly improved from pre to post therapy; medium effect-size (d = 0.52). Secondary outcomes all improved (except mania symptoms) with smaller effect sizes (d = 0.20-0.39). Patient satisfaction was high. Use of crisis services, and acute admissions were reduced compared to pre-treatment. It is possible to deliver group psychological therapy for bipolar disorder in a routine NHS setting. Improvements were observed in personal recovery, symptoms and wider functioning with high patient satisfaction and reduced service use. PMID- 30291970 TI - The 24-hour serum profiles of bone markers in healthy older men and women. AB - The process of bone turnover displays variations over 24 h, with C-terminal cross linked telopeptide of type 1 collagen (CTX) and osteocalcin exhibiting a nadir in the afternoon and a peak in the night. In contrast, N-terminal propeptide of type 1 procollagen (P1NP) did not display an apparent 24-hour rhythm. Other emerging novel biomarkers of bone, sclerostin and Dickkopf-related protein 1 (DKK1), are markers of osteocyte activity with limited data available regarding their 24-hour profiles. In this study, we aimed to extend available data on 24-hour profiles of CTX, osteocalcin, and P1NP and to assess the 24-hour profiles of sclerostin and DKK1 in healthy older men and women and to compare these between men and women. We measured these five bone markers in EDTA plasma collected every 4 h during 24 h in 37 healthy older men and women (range 52-76 years). Differences between time points were determined using repeated measures ANOVA and cosinor analyses were performed to determine circadian rhythmicity. The circadian rhythm of CTX was confirmed by the cosinor model, with women showing larger amplitude compared to men. Osteocalcin showed higher levels during nighttime compared to daytime in both men and women. For P1NP levels we observed a small but significant increase in the night in men. Sclerostin and DKK1 did not show a circadian rhythm, but sclerostin levels differed between time points. Because of the large intraindividual variation, DKK1 as measured in this study cannot be considered a reliable marker for diagnostic or research purposes. In conclusion, when measuring CTX, osteocalcin, P1NP, or sclerostin either in clinical practice or in a research setting, one should consider the 24-hour profiles of these bone markers. PMID- 30291971 TI - Combining VITEK(r) 2 with colistin agar dilution screening assist timely reporting of colistin susceptibility. AB - OBJECTIVES: The rise in carbapenem resistance among Gram-negative bacteria has renewed interest in colistin. Recently, the EUCAST-CLSI Polymyxin Breakpoints Working Group declared that broth microdilution (BMD) is the only valid method for colistin susceptibility testing. BMD is not easily incorporated into the routine work of clinical laboratories, and usually this test is incorporated serially, resulting in delayed susceptibility reporting. We tested a strategy of combining VITEK(r) 2 with a 2 MUg/mL colistin agar dilution (VITEK(r) 2/AD) screening plate to improve performance and time to reporting of colistin susceptibility. METHODS: Colistin susceptibility for 364 clinical isolates was determined by VITEK(r) 2/AD and compared with the reference standard BMD according to the ISO 20776-1:2007 and CLSI guidelines. The EUCAST colistin susceptibility breakpoint of <=2 MUg/mL was used. Escherichia coli NCTC 13846 served as quality control strain. Agreement, very major error (VME) and major error rates were determined using ISO 20776-2:2007. RESULTS: The VME rate for VITEK(r) 2 alone was 30.6% (15/49, 95% CI 18.3-45.4%), and was reduced to 10.2% (5/49, 95% CI 3.4-22.2%) using the VITEK(r) 2/AD combined testing. The combined testing had categorical agreement with BMD of 97% (354/364, 95% CI 95.0-98.7%), and a major error (ME) rate of 1.6% (5/315, 95% CI 0.5-3.7%). Using the combined testing, even against challenging strains, 349 (95.8%, 95% CI 93.3-97.7%) colistin susceptibility results could be reported, and only 15 isolates required further analysis by BMD. DISCUSSION: Our method is simple to apply and allows rapid reporting of colistin susceptibility. PMID- 30291972 TI - Changes in cognitive function among older adults: A latent profile transition analysis. AB - Cognitive decline in late life is a crucial health problem. It is important to understand the consistency and change of older adults' cognitive function in late life. Data for older adults (78 years and above) from the Health and Retirement Study (N = 1680) were used to explore meaningful subtypes of cognitive function and transitions patterns between those profiles across times. Age, gender, levels of education and nursing home were incorporated as covariates to explore the association between these variables and cognitive function transition pattern. Three cognitive function subgroups (Normal Cognitive Function, Fluid Intelligence Impairment and Cognitive Impairment) were identified. Individuals in Normal Cognitive Function status had a high probability to convert to the Fluid Intelligence Impairment status whereas the Cognitive Impairment status appeared a predominant tendency for stability. Increasing age played a significant role in fluid intelligence impairment and cognitive impairment process. Female and individuals with nursing home might be at higher risk of subsequent fluid intelligence impairment, while higher education did not protect against fluid intelligence impairment. These findings highlighted the usefulness to adopt a person-centered approach rather than a variable-centered approach, suggesting directions for future research and tailored interventions approaches to older adults with particular characteristics. PMID- 30291974 TI - Mapping the human brain's cortical-subcortical functional network organization. AB - Understanding complex systems such as the human brain requires characterization of the system's architecture across multiple levels of organization - from neurons, to local circuits, to brain regions, and ultimately large-scale brain networks. Here we focus on characterizing the human brain's large-scale network organization, as it provides an overall framework for the organization of all other levels. We developed a highly principled approach to identify cortical network communities at the level of functional systems, calibrating our community detection algorithm using extremely well-established sensory and motor systems as guides. Building on previous network partitions, we replicated and expanded upon well-known and recently-identified networks, including several higher-order cognitive networks such as a left-lateralized language network. We expanded these cortical networks to subcortex, revealing 358 highly-organized subcortical parcels that take part in forming whole-brain functional networks. Notably, the identified subcortical parcels are similar in number to a recent estimate of the number of cortical parcels (360). This whole-brain network atlas - released as an open resource for the neuroscience community - places all brain structures across both cortex and subcortex into a single large-scale functional framework, with the potential to facilitate a variety of studies investigating large-scale functional networks in health and disease. PMID- 30291975 TI - Multimodal evidence on shape and surface information in individual face processing. AB - The significance of shape and surface information for face perception is well established, yet their relative contribution to recognition and their neural underpinnings await clarification. Here, we employ image reconstruction to retrieve, assess and visualize such information using behavioral, electroencephalography and functional magnetic resonance imaging data. Our results indicate that both shape and surface information can be successfully recovered from each modality but that the latter is better recovered than the former, consistent with its key role for face representations. Further, shape and surface information exhibit similar spatiotemporal profiles, rely on the extraction of specific visual features, such as eye shape or skin tone, and reveal a systematic representational structure, albeit with more cross-modal consistency for shape than surface. More generally, the present work illustrates a novel approach to relating and comparing different modalities in terms of perceptual information content. Thus, our results help elucidate the representational basis of individual face recognition while, methodologically, they showcase the utility of image reconstruction and clarify its reliance on diagnostic visual information. PMID- 30291973 TI - Gustatory responses in macaque monkeys revealed with fMRI: Comments on taste, taste preference, and internal state. AB - Studies of the neural mechanisms underlying value-based decision making typically employ food or fluid rewards to motivate subjects to perform cognitive tasks. Rewards are often treated as interchangeable, but it is well known that the specific tastes of foods and fluids and the values associated with their taste sensations influence choices and contribute to overall levels of food consumption. Accordingly, we characterized the gustatory system in three macaque monkeys (Macaca mulatta) and examined whether gustatory responses were modulated by preferences and hydration status. To identify taste-responsive cortex, we delivered small quantities (0.1 ml) of sucrose (sweet), citric acid (sour), or distilled water in random order without any predictive cues while scanning monkeys using event-related fMRI. Neural effects were evaluated by using each session in each monkey as a data point in a second-level analysis. By contrasting BOLD responses to sweet and sour tastes with those from distilled water in a group level analysis, we identified taste responses in primary gustatory cortex area G, an adjacent portion of the anterior insular cortex, and prefrontal cortex area 12o. Choice tests administered outside the scanner revealed that all three monkeys strongly preferred sucrose to citric acid or water. BOLD responses in the ventral striatum, ventral pallidum, and amygdala reflected monkeys' preferences, with greater BOLD responses to sucrose than citric acid. Finally, we examined the influence of hydration level by contrasting BOLD responses to receipt of fluids when monkeys were thirsty and after ad libitum water consumption. BOLD responses in area G and area 12o in the left hemisphere were greater following full hydration. By contrast, BOLD responses in portions of medial frontal cortex were reduced after ad libitum water consumption. These findings highlight brain regions involved in representing taste, taste preference and internal state. PMID- 30291976 TI - A ready-to-use acidic, brushite-forming calcium phosphate cement. AB - Premixed calcium phosphate cements have been developed to simplify the usage of traditional calcium phosphate cements and reduce the influence of the setting reaction on the delivery process. However, difficulties in achieving a good cohesion, adequate shelf life and sufficient mechanical properties have so far impeded their use in clinical applications, especially for the more degradable acidic calcium phosphate cements. In this study, a brushite cement was developed from a series of ready-to-use calcium phosphate pastes. The brushite cement paste was formed via mixing of a monocalcium phosphate monohydrate (MCPM) paste and a beta-tricalcium phosphate (beta-TCP) paste with good injectability and adequate shelf life. The MCPM paste was based on a water-immiscible liquid with two surfactants and the beta-TCP paste on a sodium hyaluronate aqueous solution. The effect of citric acid as a retardant was assessed. Formulations with suitable amounts of citric acid showed good cohesion and mechanical performance with potential for future clinical applications. STATEMENT OF SIGNIFICANCE: Acidic calcium phosphate cements have attracted extensive attention as bone substitute materials due to their ability to resorb faster than basic calcium phosphate cements in vivo. However, traditionally, short working times and low mechanical strength have limited their clinical application. Premixed cements could simplify the clinical use as well as improve property reproducibility, but short shelf lives, low cohesion and low mechanical properties have restricted the development. In this study, an injectable ready-to-use two-phase system consisting of an MCPM paste and a beta-TCP paste was developed based on acidic cement. It shows good cohesion, compressive strength and adequate shelf life, which has the potential to be used in a dual chamber system for simplified and fast filling of bone defects in a minimally invasive manner. This will reduce surgery time, decrease the risk of contamination and ensure repeatable results. PMID- 30291977 TI - Antisynthetase syndrome and cardiac involvement: a rare association.

AB - Hypoxia is one of the most common physiological stressors in shrimp farming. Post transcriptional regulation by microRNAs has been recognized as a ubiquitous strategy to enable transient phenotypic plasticity and adaptation to stressful environment, but involvement of microRNAs in hypoxia stress response of penaeid shrimp remains elusive. In this study, small RNA sequencing and comparative transcriptomic analysis was conducted to construct a comprehensive microRNA dataset for the whiteleg shrimp Litopenaeus vannamei exposed to hypoxia challenge. A total of 3324 known miRNAs and 8 putative novel miRNAs were identified, providing a valuable resource for future investigation on the functional mechanism of miRNAs in shrimp. Upon hypoxia, 1213 miRNAs showed significant differential expression, and many well-known miRNAs involved in hypoxia tolerance such as miR-210, let-7, miR-143 and miR-101 were identified. Remarkably, the vast majority of these miRNAs were up-regulated, suggesting that up-regulation of miRNAs may represent an effective strategy to inhibit protein translation under stressful hypoxic condition. The differentially expressed miRNAs were potentially targeting a wide variety of genes, including those with essential roles in hypoxia tolerance such as HIF1a and p53. GO and KEGG enrichment analysis further revealed that a broad range of biological processes and metabolic pathways were over-represented. Several GO terms associated with gene transcription and translation and KEGG pathways related to cytoskeleton remodeling, immune defense and signaling transduction were enriched, highlighting the crucial roles of these cellular events in the adaptation to hypoxia. Taken together, our study revealed that the differentially expressed miRNAs may regulate host response to hypoxia by modulating the expression of stress response genes such as HIF1a and p53 and affecting key cellular events involved in hypoxia adaptation. The findings would expand our knowledge of the biochemical and molecular underpinnings of hypoxia response strategies used by penaeid shrimp, and contribute to a better understanding of the molecular mechanisms of hypoxia tolerance in decapod crustaceans. PMID- 30291982 TI - Phagocytosis and ROS production as biomarkers in Nile tilapia (Oreochromis niloticus) leukocytes by exposure to organophosphorus pesticides. AB - Organophosphorus pesticides (OPs) are broad-spectrum insecticides. One of the commonly used OPs is diazinon (DZN). The aim of this study was to evaluate the immunotoxic effect of DZN on phagocytic parameters of blood leukocytes using the teleost fish Oreochromis niloticus as a study model. For this purpose, fish were exposed in vivo to 0.97, 1.95 and 3.97 mg/L of DZN for 6 and 24 h. Our results indicated that phagocytic active cells decreased in fish exposed in vivo to 0.97 and 1.95 mg/L of DZN for 6 and 24 h. Regarding ROS production, H2O2 and O2- levels were higher on fish exposed to 1.95 mg/L for 6 and 24 h, while H2O2 production increased at 0.97 mg/L for 24 h. From this we can conclude that phagocytic parameters are sensitive to assess the effect of acute intoxication with organophosphorus pesticides on Nile tilapia. PMID- 30291983 TI - Effect of N-carbamoylglutamate supplementation on the growth performance, antioxidant status and immune response of mirror carp (Cyprinus carpio) fed an arginine-deficient diet. AB - The present study was conducted to determine the effect of dietary N carbamoylglutamate (NCG) supplementation on the growth performance, antioxidant capability and immune responses of mirror carp (Cyprinus carpio) fed an arginine (Arg)-deficient diet. A total of 630 mirror carp (41.65 +/- 0.14 g) were fed diets (Arg 1.24% of the diet) that were supplemented with 0.50% Arg (control diet) or graded levels of NCG at 0 (Arg deficiency diet), 0.04%, 0.08%, 0.12%, 0.16% and 0.20% for 8 weeks. The results showed that, compared with the control diet, the Arg-deficient diet supplementation with 0 NCG (1) decreased the final body weight (FWB), the weight gain rate (WGR) or the protein efficiency ratio (PER) and increased the feed conversion ratio (FCR); (2) decreased the concentration of Arg and nitric oxide (NO) and the activity of total nitric oxide synthetase (T-NOS) in the plasma; (3) decreased the activities of superoxide dismutase (SOD) in the proximal intestine (PI), catalase (CAT) in the PI and distal intestine (DI), and glutathione peroxidase (GPx) in PI and mid-intestine (MI) and increased the concentration of malondialdehyde (MDA) in the PI, MI and DI; and (4) decreased the activity of lysozyme in the plasma, increased the relative mRNA expression of tumor necrosis factor-alpha (TNF-alpha), interleukin1beta (IL-1beta) and interleukin 8 (IL-8) in the PI, MI and DI, and decreased the relative mRNA expression of interleukin 10 (IL-10) in the PI and MI, and transforming growth factor beta2 (TGF-beta2) in the PI, MI and DI. Compared with the Arg deficient-diet supplementation with 0 NCG, (1) 0.12% or 0.16% NCG increased the FBW, WGR and PER, and 0.16% NCG increased the FCR; (2) 0.08%-0.20% NCG increased the concentration of Arg, NO and the activity of T-NOS; (3) 0.08% NCG increased the activities of SOD in the PI and MI, and 0.12% NCG increased activities of CAT and GPx in the PI, MI and DI; and (4) 0.04%-0.20% NCG increased the activity of lysozyme, 0.04%-0.20% NCG decreased the relative mRNA expression of TNF-alpha, IL-1beta and IL-8 in the PI and MI, and 0.04%-0.20% NCG increased the relative mRNA expression of IL-10 and TGF-beta2 in the PI and MI. The present results indicated that dietary 0.12% or 0.16% NCG improved the growth performance, feed utilization, intestinal antioxidant capacity and immune response of mirror carp fed an Arg-deficient diet. PMID- 30291984 TI - Changes of microRNAs expression profiles from red swamp crayfish (Procambarus clarkia) hemolymph exosomes in response to WSSV infection. AB - MicroRNAs (miRNAs) as short noncoding RNAs play important regulatory roles in diverse biological processes by degrading the target mRNAs, and could be delivered by exosomes. WSSV is a highly pathogenic and prevalent virus, and has brought high mortality of P. clarkia. Till present, no studies focus on the miRNAs changes in exosomes during WSSV infection. To understand the different virulence of WSSV on miRNAs expression in P. clarkia hemolymph exosome, the deep sequencing was performed to compare the small RNA libraries from the hemolymph exosome of P. clarkia individuals with or without WSSV infections. From the TEM observations, NTA and Western Blot analysis, the extracted exosomes were well identified with classic characteristics. The 209 conserved miRNAs and 250 novel miRNAs were identified from the small RNA libraries. In response to WSSV infection, there were about 98 miRNAs significantly up-regulated and 59 miRNAs significantly down-regulated. The target genes prediction, GO and KEGG enrichment analysis revealed that some target genes of P. clarkia miRNAs were grouped mainly into the categories of biological regulation, immune system process, signal pathway and other more functions. This is the first report of comprehensive identification of P. clarkia hemolymph exosome miRNAs being differentially regulated in response to WSSV infection. These results will help to understand the hemolymph exosome miRNAs response to different virulence WSSV infection. PMID- 30291985 TI - Transcriptomic analysis of immunoglobulin novel antigen receptor (IgNAR) heavy chain constant domains of brownbanded bamboo shark (Chiloscyllium punctatum). AB - Cartilaginous fish are the evolutionarily oldest group of animals which possess antibodies, T cell receptors and major histocompatibility complex (MHC). The immunoglobulin novel antigen receptor (IgNAR) found in cartilaginous fish is a heavy chain homodimer which lacks light chain. The presence of non-canonical cysteine molecules and lack of CDR2 region make it more significant. To synthesize active binding domains based on variable region of IgNAR (VNAR), knowledge on the constant region dynamics play a significant role. The IgNAR exhibit species variations in its primary sequence features; hence, this study was conducted to determine the IgNAR heavy chain constant domain of the brownbanded bamboo shark (Chiloscyllium punctatum). Peripheral blood leukocytes (PBL) isolated from adult bamboo sharks were used to synthesize a cDNA library. A total of four billion residues of two million sequences (average length 218.41 bp) were obtained. Assembled sequences were aligned with published cartilaginous fish IgNAR constant region sequences. Transcriptome analysis revealed two distinct types of IgNAR in the brownbanded bamboo shark. Also, constant-1 domain sequences displayed 13 unique sequences which may reflect the least number of IgNAR gene clusters. The phylogenetic analysis revealed the closest relationship with the nurse shark (Ginglymostoma cirratum) followed by the wobbegong shark (Orectolobus maculatus) which belong to the same order Orectolobiformes. Analysis of the constant domains of the brownbanded bamboo shark IgNAR revealed an evolutionarily conserved nature and this knowledge can be used to design primers for VNAR cloning. Furthermore, knowledge on the structural features in IgNAR constant domains that increase the stability could be useful in the process of stabilizing human immunoglobulins. PMID- 30291986 TI - Chelation, formulation, encapsulation, retention, and in vivo biodistribution of hydrophobic nanoparticles labelled with 57Co-porphyrin: Oleylamine ensures stable chelation of cobalt in nanoparticles that accumulate in tumors. AB - BACKGROUND AND MOTIVATION: While small molecules can be used in cancer diagnosis there is a need for imageable diagnostic NanoParticles (NPs) that act as surrogates for the therapeutic NPs. Many NPs are composed of hydrophobic materials so the challenge is to formulate hydrophobic imaging agents. To develop individualized medical treatments based on NP, a first step should be the selection of patients who are likely responders to the treatment as judged by imaging tumor accumulation of NPs. This requires NPs with the same size and structure as the subsequent therapeutic NPs but labelled with a long-lived radionuclide. Cobalt isotopes are good candidates for NP labelling since 55Co has half-life of 17.5 h and positron energy of 570 keV while 57Co (t1/2 271.6 d) is an isotope suited for preclinical single photon emission tomography (SPECT) to visualize biodistribution and pharmacokinetics of NPs. We used the hydrophobic octaethyl porphyrin (OEP) to chelate cobalt and to encapsulate it inside hydrophobic liquid NPs (LNPs). We hypothesized that at least two additional hydrophobic axial ligands (oleylamine, OA) must be provided to the OEP-Co complex in order to encapsulate and retain Co inside LNP. RESULTS: 1. Cobalt chelation by OEP and OA. The association constant of cobalt to OEP was 2.49 * 105 M-1 and the formation of the hexacoordinate complex OEP-Co-4OA was measured by spectroscopy. 2. NP formulation and characterization: LNPs were prepared by the fast ethanol injection method and were composed of a liquid core (triolein) surrounded by a lipid monolayer (DSPC:Cholesterol:DSPE-PEG2000). The size of the LNPs loaded with the cobalt complex was 40 +/- 5 nm, 3. Encapsulation of OEP-Co-OA: The loading capacity of OEP-Co-OA in LNP was 5 mol%. 4. Retention of OEP-57Co-4OA complex in the LNPs: the positive effect of the OA ligands was demonstrated on the stability of the OEP-57Co-4OA complex, providing a half-life for retention in PBS of 170 h (7 days) while in the absence of the axial OA ligands was only 22 h. 5 Biodistribution Study: the in vivo biodistribution of LNP was studied in AR42J pancreatic tumor-bearing mice. The estimated half-life of LNPs in blood was about 7.2 h. Remarkably, the accumulation of LNPs in the tumor was as high as 9.4% ID/g 24 h after injection with a doubling time for tumor accumulation of 3.22 h. The most important result was that the nanoparticles could indeed accumulate in the AR42J tumors up to levels greater than those of other NPs previously measured in the same tumor model, and at about half the values reported for the molecular agent 57Co-DOTATATE. CONCLUSIONS: The additional hydrophobic chelator OA was indeed needed to obtain a stable octahedral OEP-Co-4OA. Cobalt was actually well retained inside LNP in the OEP-Co-4OA complex. The method described in the present work for the core-labelling of LNPs with cobalt is now ready for labeling of NPs with 55Co, or indeed other hexadentate radionuclides of interest for preclinical in vivo PET-imaging and radio-therapeutics.

AB - Pattern recognition receptors, including the Toll-like receptors (TLRs), are important in the induction and activation of two critical arms of the host defence to pathogens and microorganisms: the rapid innate immune response (as characterised by the production of Th1 promoting cytokines and type 1 interferons) and the adaptive immune response. Through this activation, ligands and agonists of TLRs can enhance immunotherapeutic efficacy. Resiquimod is a small (water-soluble) agonist of the endosome-located Toll-like receptors 7 and 8 (TLR7/8). However due to its molecular attributes it rapidly distributes throughout the body after injection. To circumvent this, these TLR agonists can be incorporated within delivery systems, such as liposomes, to promote the co delivery of both antigen and agonists to antigen presenting cells. In this present study, resiquimod has been chemically conjugated to a lipid to form a lipid-TLR7/8 agonist conjugate which can be incorporated within immunogenic cationic liposomes composed of dimethyldioctadecylammonium bromide (DDA) and the immunostimulatory glycolipid trehalose 6,6' - dibehenate (TDB). This DDA:TDB TLR7/8 formulation offers similar vesicle characteristics to DDA:TDB (size and charge) and offers high retention of both resiquimod and the electrostatically adsorbed TB subunit antigen Ag85B-ESAT6-Rv2660c (H56). Following immunisation through the intramuscular (i.m.) route, these cationic DDA:TDB-TLR7/8 liposomes form a vaccine depot at the injection site. However, immunisation studies have shown that this biodistribution does not translate into notably increased antibody nor Th1 responses at the spleen and draining popliteal lymph node compared to DDA:TDB liposomes. This work demonstrates that the conjugation of TLR7/8 agonists to cationic liposomes can promote co-delivery but the immune responses stimulated do not merit the added complexity considerations of the formulation. PMID- 30291988 TI - Stress, female reproduction and pregnancy. AB - Stress is one of the commonest and underappreciated causes of reproductive frailty in women. The stress system leads to adaptive responses via mobilization of hormonal systems. Adaptability and resistance to stress are fundamental to life. The response to stressors depends on the type of stressor, the timing and duration of stress, the genetic predisposition, personality characteristics, and the way of coping with stress. The hypothalamic-pituitary-adrenal (HPA) axis has a direct inhibitory action on the hypothalamic-pituitary-ovarian (HPO) axis at multiple levels. Acute and chronic stress impairs reproduction, eventually acting on varying mechanisms. Undernutrition, over-training, and psychological stress contribute to hypothalamic amenorrhea via reduced HPO activity. In utero stress exposure is a significant predictor of subsequent adult telomere length. Some of the metabolic consequences of intrauterine growth restriction can be mitigated by ensuring early appropriate catch-up growth, while avoiding excessive weight gain if relative hypercortisolism is not installed. The effect of maternal stress on fetuses regarding fetal HPA axis responsiveness (increased or decreased) remains under investigation. Maternal stress and depression are associated with structural and functional changes of brain parts such as hippocampus. In utero stress modifies epigenetically components of the HPA axis which can be transmitted transgenerationally. PMID- 30291989 TI - Multi-omics analysis: Repeated exposure of a 3D bronchial tissue culture to whole cigarette smoke. AB - Cigarette smoke (CS) is a major risk factor in the development of chronic inflammatory lung diseases such as chronic obstructive pulmonary disease. A comprehensive investigation of the biological impacts of chronic CS exposure on lung tissue is therefore important for understanding the pathogenesis of lung disease. We used three-dimensional (3D) organotypic human bronchial tissue cultures and metabolomics, transcriptomics, and proteomics to investigate changes in biological processes affected by repeated whole-CS exposure. We found that CS perturbed central carbon metabolism in relation with oxidative stress responses. Epidermal growth factor receptor, which is involved in the early-stage pathogenesis of airway diseases, was identified as a key regulator of the perturbed processes. Proteomic analysis of proteins in the apical surface liquid of the 3D bronchial tissue cultures indicated that repeated whole-CS exposure induced alterations in the secretion of several known biomarkers of airway diseases, including mucins and matrix metalloproteinases. These findings are consistent with observations from lung disease patients. Overall, our results suggest that 3D bronchial tissue cultures can provide valuable information on tissue-specific alterations in biological processes induced by chronic exposure to CS. PMID- 30291990 TI - SkinEthicTM HCE Eye Irritation Test: Similar performance demonstrated after long distance shipment and extended storage conditions. AB - Assessment of ocular irritation risk is an international regulatory requirement in the safety evaluation of products. In response to this need, L'Oreal developed the SkinEthicTM Human Corneal Epithelium (HCE) Eye Irritation Test (EIT) that has been included in OECD Test Guideline 492. SkinEthicTM HCE EIT is able to correctly and reliably identify chemicals not requiring classification versus labelling for eye irritation or serious eye damage according to UN GHS. In an effort to promote its global use, the performance of the method was evaluated after long-distance shipment and compared to European shipment conditions. Results obtained by Cosmos Technical Center (Japan) after extended tissues transit were compared to results obtained in L'Oreal (France). Thirty-nine out of 40 blinded chemicals, representing different functional chemical classes, were consistently classified in both laboratories. The SkinEthicTM HCE EIT test method was also evaluated for its performance after extended storage of the tissues. The performance was in agreement with the values reported in OECD TG 492, with an overall accuracy of 87.1% (based on 119 chemicals), sensitivity of 95.5% and specificity of 73.5%. The reliability and relevance of SkinEthicTM HCE EIT test method after long-distance shipment and extended storage remain in agreement with regulatory validation criteria. PMID- 30291991 TI - Microplastic testing in vitro: Realistic loading of pollutants, surfactant-free solid surface-dosing and bioanalytical detection using a sensitivity-optimized EROD assay. AB - Microplastic particles (MPs) are emerging contaminants in aquatic environments, which are assumed to play a role as vectors for lipophilic pollutants, as the particles bear a potential for the accumulation of lipophilic contaminants from the water phase on the MPs' surface and subsequent release in contact with organisms. In an attempt to allow the bioanalytical detection and quantitatively estimate bioavailability of MP-bound pollutants under realistic conditions in vitro, a protocol was developed for water-based loading of lipophilic substances to MPs using a solid-phase extraction (SPE) approach and subsequent detection of the substances in a sensitivity-enhanced 7-ethoxyresorufin-O-deethylase (EROD) assay with RTL-W1 cells. Exemplarily, particles were loaded with benzo[k]fluoranthene (BkF), which was shown to bind to MPs with high affinity. Spiked particles were added to the surface of the culture medium, where they released low, but consistent amounts of BkF, which were quantified by EROD induction. Additionally, a geometrical model was developed for the estimation of numbers, surface areas and masses of MPs interacting with medium. The approach presented allows the experimental in vitro examination of the postulated function of MP as a pollutant vector in a highly sensitive animal-experimentation-free test system. PMID- 30291992 TI - Influence of distortions of recorded diffraction patterns on strain analysis by nano-beam electron diffraction. AB - Images acquired in transmission electron microscopes can be distorted for various reasons such as e.g. aberrations of the lenses of the imaging system or inaccuracies of the image recording system. This results in inaccuracies of measures obtained from the distorted images. Here we report on measurement and correction of elliptical distortions of diffraction patterns. The effect of this correction on the measurement of crystal lattice strain is investigated. We show that the effect of the distortions is smaller than the precision of the measurement in cases where the strain is obtained from shifts of diffracted discs with respect to their positions in images acquired in an unstrained reference area of the sample. This can be explained by the fact that diffraction patterns acquired in the strain free reference area of the sample are distorted in the same manner as the diffraction patterns acquired in the strained region of interest. In contrast, for samples without a strain free reference region such as nanoparticles or nanoporous structures, where we evaluate ratios of lattice plane distances along different directions, the distortions are usually not negligible. Furthermore, two techniques for the detection of diffraction disc positions are compared showing that for samples in which the crystal orientation changes over the investigated area it is more precise to detect the positions of many diffraction discs simultaneously instead of detecting each disc position independently. PMID- 30291993 TI - Disseminated tumor cells predict efficacy of regional nodal irradiation in early stage breast cancer. AB - BACKGROUND: The disseminated tumor cells (DTC) are collected in the bone marrow and are the witness of micrometastatic spread. We previously reported that DTC could be a predictive factor of the efficacy of regional node irradiation (IMN/SCN: internal mammary nodes & supra-infra clavicular nodes). In this article, we report the long-term results (>10 years) on the impact of DTC status in early-stage breast cancer. METHODS: Patients with localized breast cancer were eligible for this prospective cohort. DTC was obtained from a medullary iliac crest sample performed prior to any primary therapy. DTC status was prospectively assessed by pathologists. Irradiation volumes were defined per standard of care. Cumulative incidence rates and hazard ratio were obtained using both Cox and Fine Gray models. Interaction tests were performed to confirm the predictive value of DTC status in a multivariate analysis. RESULTS: 620 patients with localized breast cancer were included. Overall, 94 patients (15.2%) were DTC-positive. After a median follow-up of 11.7 years, 47 patients (7.6%) experienced a locoregional relapse. DTC detection was associated with a higher risk of locoregional relapse in univariate and multivariate analyses (Cox, HR=3.26, 95%CI=[1.6;5.7], p=0.001). In the multivariate subgroup analysis, IMN/SCN irradiation significantly reduced locoregional relapse for DTC-positive patients comparing to DTC-negative patients (interaction test: HR=0.3, 95%CI [0.1;0.9], p=0.02). IMN/SCN was the only irradiation volume with a impact on locoregional relapse in patients, according to their DTC status, and the predictive value of DTC status for the benefit of locoregional irradiation was independent of the locoregional nodal status. CONCLUSION: This long-term analysis confirms the predictive impact of DTC status on the efficacy of regional radiotherapy on locoregional relapse in early breast cancer. After further studies, DTC status could be a decision tool to better tailor adjuvant radiation therapy in early stage breast cancer patients. PMID- 30291994 TI - Validation of Effective Dose as a Better Predictor of Radiation Pneumonitis Risk than Mean Lung Dose: Secondary Analysis of a Randomized Trial. AB - PURPOSE: To confirm the superiority of effective dose (Deff) over mean lung dose (MLD) for predicting risk of radiation pneumonitis (RP), using data from patients on a randomized trial of intensity-modulated radiotherapy (IMRT) versus passively scattered proton therapy (PSPT). METHODS: The prescribed target dose for the 203 evaluated patients was 66-74 Gy(RBE) in 33-37 fractions with concurrent carboplatin/paclitaxel. Time to grade >2 RP was computed from the start of radiotherapy, with disease recurrence or death considered censoring events. Generalized Lyman models of censored time to RP were constructed with MLD or Deff as the dosimetric parameter. Smoking status (current, former, never) was also analyzed. RESULTS: Of the 203 patients, 46 experienced grade >=2 RP (crude incidence 23%), at a median 3.7 months (range, 0.6-12.6 months). The volume parameter estimated for the Deff model was n=0.5, confirming estimates from earlier studies. Compared with MLD (in which n=1), the dosimetric parameter Deff, computed using n=0.5, resulted in a better fit of the Lyman model to the clinical data (P=0.010). Using Deff, the model describes RP risk for IMRT and PSPT data combined, as no further improvement was found from separate fits (P=0.558). Based on Deff, predicted RP risk per patient ranged from 24 percentage points lower to 19 percentage points higher than predictions based on MLD. For patients with similar MLD, Deff predicted higher risk, on average, for PSPT over IMRT. Current smokers had a lower risk of RP than former smokers and nonsmokers (P=0.021). CONCLUSIONS: We used data from a randomized trial to validate our previous finding that Deff with n=0.5 (corresponding to root mean squared dose) is a better predictor of RP than MLD. Differences between Deff and MLD indicate that delivering higher doses to smaller lung volumes (vs. lower doses to larger volumes) increases RP risk. We further corroborated that current smoking is associated with decreased RP risk. PMID- 30291995 TI - Treatment of diverticular disease, targeting symptoms or underlying mechanisms. AB - Diverticular disease (DD) is a highly prevalent disease in western industrialized countries that encompasses a complex set of disorders. Because of its complexity and heterogeneity, both from a pathogenic and a clinical point of view, the management of this disease represent a challenge in clinical practice. This review aims to analyze and summarize the most recent evidence on the medical strategies for DD, considering separately the different stages of the disease, from prevention of diverticula formation to treatment of acute diverticulitis and prevention of recurrences. Based on some evidence, dietary fiber is useful to prevent diverticula formation and in diverticulosis, with no pharmacological treatment in these settings. Treatment of symptomatic uncomplicated diverticular disease as well as primary prevention of acute diverticulitis is based on probiotics, fibres, mesalazine and rifaximin, individually or as combination therapy, although a standard approach has not yet been defined. On the contrary, in acute diverticulitis (AD) recent acquisitions have clarified and standardized the role of systemic antibiotics, reserving its use only to complicated forms and in selected cases of uncomplicated disease. Secondary prevention of AD is essentially based on mesalazine and rifaximin but, despite promising results, no strong evidence have been produced. To date, grey areas remain in the medical management of DD. PMID- 30291996 TI - Altered composition of the gut microbiome in patients with drug-resistant epilepsy. AB - OBJECTIVE: The relationship between the gut microbiota and the central nervous system has been gradually recognized while whether microbiome plays a role in the pathogenesis of drug-resistant epilepsy is still unknown. The aim of our work was to explore whether dysbiosis is involved in the mechanism of drug-resistant epilepsy. METHODS: Patients with epilepsy attending West China Hospital of Sichuan University were enrolled from March to May 2017. Patients were grouped into drug-resistant (n = 42) and drug-sensitive (n = 49) groups, another 65 healthy controls were from the same families of the patients. The fecal samples were collected and the microbiome composition was analyzed by high-throughout sequencing of the 16s ribosomal DNA. RESULTS: We found that the gut microbial community of drug-resistant epilepsy was significantly altered with an abnormal increased abundance of rare flora. While the gut microbiome composition of drug sensitive epilepsy was similar with that of healthy controls. Specifically, patients with four seizures per year or fewer showed an increase of Bifidobacteria and Lactobacillus than those with more than four seizures per year. CONCLUSIONS: Dysbiosis may be involved in the mechanism of drug-resistant epilepsy and restoring the gut microbial community may be a novel therapeutic method for drug-resistant epilepsy. PMID- 30291997 TI - Implementing community health worker-patient pairings at the time of hospital discharge: A randomized control trial. AB - BACKGROUND: In 2011, there were approximately 3.3 million adult 30-day all-cause hospital readmissions in the US generating $41.3 billion in hospital costs. Community health worker (CHW) care delivery is one of very few interventions demonstrated to reduce health care utilization among populations with chronic disease. While there are a number of studies demonstrating improved disease specific outcomes with CHW interventions, studies examining the effect of CHW care delivery on 30-day readmission rates are rare. METHODS: This study is a randomized control trial designed to determine if linking hospitalized patients with chronic disease to community health workers (CHWs) can decrease 30-day readmissions. Participants were randomly assigned to receive the 30-day CHW intervention or usual care (no CHW). All study participants completed surveys at baseline and the end of the study 30 days post-discharge. The primary outcome was 30-day readmission and secondary outcomes included emergency department visits, missed appointments, and patient satisfaction. RESULTS: We plan to enroll 1200 hospitalized patients during a 24-month intervals. As of December 2017, 350 patients have been consented and randomly assigned to either the intervention or control arm. A number of challenges have been encountered in implementing a CHW initiative at the time of hospital discharge. CONCLUSION: This trial tests the effectiveness of CHW care delivery at the time of hospital discharge in reducing 30-day readmission rates and improving outcomes among patients with chronic disease. We describe and discuss challenges in launching this CHW intervention and strategies utilized to overcome these obstacles.

PMID- 30291999 TI - Interaction of Group B Streptococcus sialylated capsular polysaccharides with host Siglec-like molecules dampens the inflammatory response in tilapia. AB - Group B Streptococcus (GBS, S. agalactiae) infection in tilapia (Oreochromis niloticus) causes widespread death of this species and is a significant issue for the aquaculture industry. The major virulence factor for GBS is its sialylated capsular polysaccharides (CPs). These CPs interact with sialic acid-binding immunoglobulin-like lectins (Siglecs) on the host immune cells to regulate the downstream inflammatory response and evade detection. Previously, we cloned multiple Siglec-like molecules from an O. niloticus cDNA library, all of which were shown to interact with the sialylated CPs of GBS. In the present study, we investigated the effects of GBS infection on the expression of pro- and anti inflammatory cytokines in O. niloticus as well as OnSiglec-like-transfected macrophage cells. Eukaryotic expression vectors containing full-length OnSiglec-1 like, -4b-like, -14-like were constructed and used to transfect RAW264 macrophages in vitro as well as live tilapia in vivo prior to GBS infection. The expression of the anti-inflammatory cytokine interleukin (IL)-10 and the pro inflammatory cytokines tumor necrosis factor (TNF)-alpha, IL-6, and interferon (INF)-beta were then analyzed by qPCR. Our results indicate that as infection progressed, IL-10 expression was significantly upregulated, while that of TNF alpha and IL-6 were significantly downregulated in the OnSiglec-like-transfected cells. INF-beta expression was also downregulated in cells transfected with OnSiglec-1-like and -4b-like, but was not significantly effected in OnSiglec-14 like-transfected cells. Notably, the magnitude of these cytokine expression changes was greatly decreased when a DeltaneuA GBS mutant was used to infect the OnSiglec-1-like-transfected cells. In GBS-infected tilapia, IL-10 expression was significantly upregulated in all tissues, whereas INF-beta expression in the spleen, kidney, and gills was significantly downregulated at 12 hpi. While the expression of TNF-alpha was slightly upregulated, this change was not significant. In GBS DeltaneuA mutant-infected O. niloticus, IL-10 expression in all of the tissues was significantly lower than that observed for the wild-type GBS group, while TNF-alpha expression was higher in the mutant infected group. There was no significant difference in INF-beta expression between the two groups. Taken together, sialylated CPs on GBS appear to interact with host OnSiglec-like molecules to transmit negative regulatory signals via enhanced anti inflammatory cytokine IL-10 production and reduced pro-inflammatory cytokine production, ultimately leading to dampening of the host immune response. The results of this study further elucidate the molecular mechanism underlying GBS infection in tilapia and also provide candidate drug target molecules. PMID- 30292000 TI - Incidence of postoperative nausea and vomiting after laparoscopic sleeve gastrectomy with staple line reinforcement with oversewing and staple line inversion vs buttressing material: A randomized clinical trial. AB - BACKGROUND: Postoperative nausea and vomiting are relevant complications after restrictive bariatric procedures, such as sleeve gastrectomy, mainly secondary to a drastic reduction in the gastric volume. However, other causes can be involved. The aim of this study was to determine the incidence of postoperative nausea and vomiting (PONV) after laparoscopic sleeve gastrectomy (LSG), with staple line reinforcement with oversewing vs buttressing material. PATIENTS AND METHODS: A prospective randomized clinical trial of all the patients undergoing LSG was performed. Patients were divided into 2 groups: patients undergoing staple line inversion (Group 1) and patients undergoing staple line reinforcement with buttressing material (Group 2). Nausea and vomiting were assessed by the Postoperative Nausea and Vomiting Intensity Scale. RESULTS: A total of 100 females were included in the study, 50 in each group. Mean operative time was 66.1 +/- 11.6 min in Group 1 and 55.4 +/- 9.4 in Group 2 (p < 0.001). There were no significant differences in staple line leaks and bleeds between groups. The PONV intensity score at 6 h was 316.4 in Group 1 and 77.1 in Group 2 (p < 0.001). 24 h after surgery, the PONV intensity score was 86 in Group 1 and 7.9 in Group 2 (p = 0.022). CONCLUSION: The reinforcement with a running suture in LSG creates more PONV and increases the duration of the symptoms during the first hours after surgery, and prevents from early oral intake in a greater number of cases, when compared with the use of buttressing material as reinforcement method. PMID- 30292001 TI - The efficacy and safety of parecoxib for reducing pain and opioid consumption following total knee arthroplasty: A meta-analysis of randomized controlled trials. AB - BACKGROUND: The goal of the current meta-analysis is to make a credible and overall assessment about the efficacy and safety of parenteral parecoxib for pain control in total knee arthroplasty (TKA). METHODS: The following online electronic databases, such as PubMed, Cochrane, Embase, were searched to identify the qualified studies updated to August 2018 according to the index words. Weight mean difference (WMD) or risk difference (RD) along with 95% confidence interval (CI) was utilized to analyze the main outcomes. To assess the heterogeneity of study trial and determine the model for analysis (random-effect model or fixed effect model), I2 tests and Chi-squared were conducted. We utilized the STATA 10.0 (TX, USA) to perform all statistical analyses. RESULT: Totally, four studies were involved in the meta-analysis with 418 patients. The present meta-analysis indicated that intravenous parecoxib was associated with a significantly improved pain relief and opioid consumption after TKA. There was no increased risk of adverse effects related to parecoxib. CONCLUSION: Intravenous parecoxib is effective in reducing knee pain and opioid consumption in patient with TKA. Further well-designed research with large simple sizes is necessary to confirm our conclusion. PMID- 30292002 TI - A novel hybrid fixation (coracoclavicular screw supplemented with K-wire) for the treatment of acute acromioclavicular joint dislocation: A prospective study. AB - OBJECTIVE: The aim of this study was to compare the radiological and clinical outcomes of clavicular hook plate fixation and the coracoclavicular lag screw supplemented with K-wire fixation in the treatment of acute acromioclavicular joint dislocation. METHODS: Between January 2012 to December 2015, 81 patients with acute acromioclavicular joint dislocation were included in this prospective study. 43 patients were treated with clavicular hook plate fixation (Group A) and 38 patients were treated with coracoclavicular lag screw supplemented with K-wire fixation (Group B). Incision length, operation duration, blood loss volume, intraoperative fluoroscopy times and length of hospitalization were recorded. Radiographic outcomes, functional outcomes and complications were also recorded. RESULTS: Both two groups could achieve good radiographic and functional outcomes after operation. Group B exhibited significantly shorter operation duration, shorter length of incision, less blood loss volume and shorter length of hospitalization than Group A (P < 0.001). In addition, significant difference could be found between the two groups regarding the VAS scores three month postoperatively and the final follow-up (P < 0.001). However, there was no significant difference in radiographic and functional outcomes between the two groups (P > 0.05). CONCLUSION: The two groups can both achieve satisfactory radiological and functional outcomes in treating acute AC joint dislocation. However, CC screw fixation supplemented with K-wire exerts some advantages regarding the incision length, operation duration, blood loss volume, length of hospitalization. Furthermore, it can better relieve the pain caused by dislocation. Therefore, the novel hybrid fixation (CC screw fixation supplemented with K-wire) provides an alternative treatment for acute AC joint dislocation. PMID- 30292003 TI - Polarization inversion applied to proton MAS-NMR spectroscopy - Methylene and methine free proton NMR spectra. AB - Polarization-inversion (PI) has been applied to proton magic angle spinning (MAS) NMR spectra recorded under fast MAS conditions. The combination of cross polarization (CP) from carbon to proton and subsequent polarization-inversion produces strong oscillatory behavior in the proton signal intensities at high MAS speeds of 60 kHz. It is observed that by a suitable choice of the polarization inversion time, a proton spectrum free of methylene and methine protons can be obtained. Such a spectrum, on the one hand, increases the resolution of the crowded proton spectrum and on the other hand provides exclusively chemical shifts of protons such as NH, OH and SH which might otherwise overlap with carbon attached protons. The oscillations observed during PI can also be used to estimate the dipolar coupling between proton and carbon by Fourier transformation of data acquired at equally incremented time periods. The utility of the above ideas has been demonstrated on a set of molecules with both 13C labeled and 13C in natural abundance. PMID- 30292004 TI - Mineralogy and buffer identity effects on RDX kinetics and intermediates during reaction with natural and synthetic magnetite. AB - Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) is known to undergo reduction mediated by ferrous iron in the presence of minerals, including magnetite. Idealized laboratory conditions may not provide representative reaction kinetics or pathways compared to field conditions. The effects of magnetite mineral morphology, the aquifer material matrix, the presence of aqueous Fe(II), and the buffer identity on RDX reduction kinetics and intermediate formation are investigated in this work. Reactions in bicarbonate buffer were substantially slower than those performed in 3-(N-morpholino)propanesulfonic acid (MOPS) buffer, and the presence of quartz and clays in magnetite-containing aquifer material resulted in slower reaction kinetics and production of additional iron oxide phases. Buffer identity also changed the rate controlling step and reaction product distribution. Conditions as close to those expected in field systems are necessary to evaluate the reaction rates and pathways of RDX in reduced groundwater systems.

PMID- 30292006 TI - Virus detection in high-throughput sequencing data without a reference genome of the host. AB - Discovery of novel viruses in host samples is a multidisciplinary process which relies increasingly on next-generation sequencing (NGS) followed by computational analysis. A crucial step in this analysis is to separate host sequence reads from the sequence reads of the virus to be discovered. This becomes especially difficult if no reference genome of the host is available. Furthermore, if the total number of viral reads in a sample is low, de novo assembly of a virus which is a requirement for most existing pipelines is hard to realize. We present a new modular, computational pipeline for discovery of novel viruses in host samples. While existing pipelines rely on the availability of the hosts reference genome for filtering sequence reads, our new pipeline can also cope with cases for which no reference genome is available. As a further novelty of our method a decoy module is used to assess false classification rates in the discovery process. Additionally, viruses with a low read coverage can be identified and visually reviewed. We validate our pipeline on simulated data as well as two experimental samples with known virus content. For the experimental samples, we were able to reproduce the laboratory findings. Our newly developed pipeline is applicable for virus detection in a wide range of host species. The three modules we present can either be incorporated individually in other pipelines or be used as a stand alone pipeline. We are the first to present a decoy approach within a virus detection pipeline that can be used to assess error rates so that the quality of the final result can be judged. We provide an implementation of our modules via Github. However, the principle of the modules can easily be re-implemented by other researchers. PMID- 30292007 TI - Mutations of Mycobacterium tuberculosis induced by anti-tuberculosis treatment result in metabolism changes and elevation of ethambutol resistance. AB - Selective pressure from antibiotic use is one of the most important risk factors associated with the development of drug resistance in Mycobacterium tuberculosis (MTB). However, the mechanisms underlying drug resistance at the molecular level remain partly unclear. Therefore, the purpose of this study was to investigate the potential functional effect of novel mutations arising from anti-tuberculosis treatment. We analyzed two multidrug-resistant TB (MDR-TB) isolates from the same patient; one collected before and one almost a year after commencing MDR-TB treatment. The post-treatment isolate exhibited elevated ethambutol resistance. We sequenced the whole genomes of the two clinical isolates and detected six novel polymorphisms affecting the genes Rv1026, nc0021, Rv2155c, Rv2437, and Rv3696c, and the intergenic region between Rv2764c and Rv2765. Metabolomics approach was used to reveal the effect of the found variation on the metabolic pathways of MTB. Partial least squares-discriminant analysis showed a clear differentiation between the two isolates, involving a total of 175 metabolites. Pathway analysis showed that these metabolites are mainly involved in amino sugar and nucleotide sugar metabolism, beta-alanine metabolism, sulfur metabolism, and galactose metabolism. The increased ethambutol resistance exhibited by the post treatment MDR-TB strain could speculatively be linked to the identified genetic variations, which affected the synthesis of a number of metabolites associated with sources of carbon and energy. This may have been the main factor underlying the increased ethambutol resistance of this isolate. PMID- 30292008 TI - Detection of radon with biosensors based on the lead(II)-induced conformational change of aptamer HTG and malachite green fluorescence probe. AB - The aim of this paper is to assemble a new biosensor for detecting the accumulated radon dose in the environment to achieve rapid monitor of radon. Based on the correlation between radon and its stable decay daughter 210Pb, a biosensor using the lead-induced specific aptamer HTG conformational changes, and the organic dye malachite green (MG) as a fluorescent probe was assembled. In these studies, we explored a novel, sensitive, label-free, fluorescence biosensing method for the detection of both radon and lead. The fluorescence intensity difference has a linear relationship with Pb2+ and the accumulated radon concentration from 6.87 * 103 Bq.h/m3 to 3.49 * 105 Bq.h/m3. The lead and radon detection limits of this method are 6.7 nmol/L and 2.06 * 103 Bq.h/m3, respectively. The student's t-test results indicated that the new method was reliable and stable. The detection method is sensitive, accurate, easy to operate, has a wide linear range and is highly selective. In the sampling and determination processes of radon, the radiation harm to human health can be effectively avoided. PMID- 30292009 TI - Peripheral Blood versus Bone Marrow from Unrelated Donors: Bone Marrow Allografts Have Improved Long-Term Overall and Graft-versus-Host Disease-Free, Relapse-Free Survival. AB - Peripheral blood (PB) and bone marrow (BM) from unrelated donors can serve as a graft source for hematopoietic cell transplantation (HCT). Currently, PB is most commonly used in roughly 80% of adult recipients. Determining the long-term impact of graft source on outcomes would inform this decision. Data collected by the Center for International Blood and Marrow Transplant Research from 5200 adult recipients of a first HCT from an 8/8 or 7/8 HLA antigen-matched unrelated donor for treatment of acute leukemia, chronic myelogenous leukemia, or myelodysplastic syndrome between 2001 and 2011 were analyzed to determine the impact of graft source on graft-versus-host disease (GVHD) relapse-free survival (GRFS), defined as freedom from grade III/IV acute GVHD, chronic GVHD requiring immunosuppressive therapy, relapse, and death, and overall survival. GRFS at 2 years was superior in BM recipients compared with PB recipients (16%; 95% confidence interval [CI], 14% to 18% versus 10%; 95% CI, 8% to 11%; P <.0001) in the 8/8 HLA-matched cohort and 7/8 HLA-matched cohort (11%; 95% CI, 8% to 14% versus 5%; 95% CI, 4% to 7%; P = .001). With 8/8 HLA-matched unrelated donors, overall survival at 5 years was superior in recipients of BM (43%; 95% CI, 40% to 46% versus 38%; 95% CI, 36% to 40%; P = .014). The inferior 5-year survival in the PB cohort was attributable to a higher frequency of deaths while in remission compared with the BM cohort. For recipients of 7/8 HLA-matched grafts, survival at 5 years was similar in BM recipients and PB recipients (32% versus 29%; P = .329). BM grafts are associated with improved long-term GRFS and overall survival in recipients of matched unrelated donor HCT and should be considered the unrelated allograft of choice, when available, for adults with acute leukemia, chronic myelogenous leukemia, and myelodysplastic syndrome. PMID- 30292010 TI - Patient Perspectives Regarding Allogeneic Bone Marrow Transplantation in Myelofibrosis. AB - Hematopoietic stem cell transplantation (HCT) is a curative treatment for patients with myelofibrosis (MF); however, many HCT-eligible patients decline this potentially life-saving procedure. The reasons behind this decision are not clear. We sought to survey patients with MF to understand their perspective on HCT. A 63-question survey was posted on myeloproliferative neoplasm patient advocacy websites. A total of 129 patients with MF responded to the survey. Among these patients, 49 (41%) were referred for HCT, and 41(32%) attended the transplantation consult. Of the patients who attended the transplantation consult, 24 (59%) did not plan on going on to HCT, and 16 (41%) intended to proceed with HCT. Reasons for the decision to not undergo transplantation included the desire to not be ill, desire to not spend time in the hospital, and concerns about overall quality of life. Specifically, concerns related to financial impact and the risk of graft-versus-host disease (GVHD) were expressed. Patients who decided to proceed with HCT felt that this would extend their survival and allow them to be around family for longer. This is the first survey to investigate patient perceptions regarding HCT for MF. Less than one-half of the patients were referred for HCT, and of those, less than one-half planned on proceeding with the transplantation, suggesting that many patients do not receive this life-saving procedure. Further exploration of the basis of patients' reluctance to proceed with HCT is warranted. PMID- 30292011 TI - Umbilical Cord Blood Transplantation Using Reduced-Intensity Conditioning without Antithymocyte Globulin in Adult Patients with Severe Aplastic Anemia. AB - Umbilical cord blood transplantation (UCBT) is a possible option for patients with aplastic anemia (AA) without a related or unrelated HLA-matched donor, particularly if immunosuppressive therapy (IST) has failed or transplantation is urgently needed. However, a higher rate of graft failure after UCBT remains a major problem, and the optimal conditioning regimen for stable engraftment after UCBT has not been established. Here we investigated 6 adult patients with AA who underwent UCBT using a reduced-intensity conditioning (RIC) regimen comprising fludarabine 125 mg/m2, cyclophosphamide 120 mg/kg, and 4 Gy of total body irradiation (Flu/CY/TBI4Gy) without antithymocyte globulin (ATG). Five patients underwent UCBT after IST failure, and 1 patient underwent UCBT as a first-line treatment due to a fulminant clinical finding of a neutrophil count of 0, despite granulocyte colony-stimulating factor administration. Regarding graft-versus-host disease (GVHD) prophylaxis, 2 patients received tacrolimus plus short-term methotrexate and 4 patients received tacrolimus plus mycophenolate mofetil, and all patients achieved sustained engraftment of both neutrophils and platelets, at a median of 17.5 days (range, 14 to 37 days) and 38.5 days (range, 31 to 86 days), respectively, with complete donor chimerism confirmed in all patients at a median of 14 days (range, 14 to 32 days). Three patients developed grade II acute GVHD (aGVHD), but grade III/IV aGVHD was not observed, whereas 4 patients developed chronic GVHD involving only skin. At the time of this report, all 6 patients were alive without the need for blood transfusion, at a median follow-up of 16 months (range, 12 to 131 months). Although further study is needed, our findings suggest that conditioning with Flu/CY/TBI4Gy without ATG might allow stable engraftment in UCBT for adults with AA. PMID- 30292012 TI - Development of aerobic granular sludge under tropical climate conditions: The key role of inoculum adaptation under reduced sludge washout for stable granulation. AB - Aerobic granular sludge (AGS) is a promising technology for wastewater treatment. However, the success of the process depends on the formation of stable granular biomass, which is associated with the microbiological aspects of the sludge and reactor operating conditions. In this study, the development of AGS from a poor nitrifying flocculent sludge obtained in a sewage treatment plant designed only for organic matter removal was assessed in a sequencing batch reactor (SBR) under tropical climate conditions (temperatures of 28 +/- 4 degrees C). The results showed that, despite the alternating anaerobic-aerobic conditions during the granules selection phase under high sludge washout rates (low settling time), readily biodegradable organic matter was mainly removed aerobically. The formed granules were unstable, exhibiting a substantial amount of filaments and pasty consistency. The biomass characteristics (e.g., sludge volume index, density, diameter and settling velocity) were negatively impacted as complete granulation was reached, while biomass loss and degranulation became inevitable. Poor nitrification and no enhanced biological phosphate removal (EBPR) were observed. Implementation of a new operational strategy incorporating an adaptation of the seed sludge under reduced washout conditions (high settling time) prior to the granules selection stage enabled most of the influent organics to be removed anaerobically. Besides allowing a feast-famine regime to be established in the reactor, the sludge acclimation phase favoured the development of slow-growing organisms and suppressed the appearance of filamentous-like structures. Fast settling granules with regular shape remained stable in the long-term, while high ammonium (>95%) and total nitrogen removal (>90%) was obtained. However, EBPR activity was very unstable, most likely due to the high temperatures. The findings of this study are important for the spreading of the AGS technology worldwide, especially in developing countries where the conditions are different in all aspects. PMID- 30292013 TI - Evaluation of direct and alternating current on nitrate removal using a continuous electrocoagulation process: Economical and environmental approaches through RSM. AB - This study aims to investigate the effects of alternating current (AC) and direct current (DC) for nitrate removal and its operating costs by using a continuous electrocoagulation (CEC) process. For this purpose, two series of 31 experiments, which were designed by response surface method (RSM), were carried out in both cases of the AC and the DC modes. In each series, the effect of selected parameters, namely, initial nitrate concentration, inlet flow rate, current density and initial pH along with their interactions on the nitrate removal efficiency as well as its operating costs, as responses, were investigated separately. According to the analysis of variance (ANOVA), there is a reasonable agreement between achieving results and the experimental data for both responses. The nitrate removal in the AC mode was slightly more efficient than that of the DC mode. In addition, the average operating costs of the DC mode, including the energy and the electrode consumption for the CEC process were achieved 54 US$/(kg nitrate removed); whereas this amount was calculated 29 US$/(kg nitrate removed) for the AC mode. Therefore, the average of the operating costs was improved more than 40% using the AC mode, which was mainly related to reduction of aluminum electrode consumption. PMID- 30292014 TI - The transition towards a bio-based economy: A comparative study based on social network analysis. AB - This paper focuses on the development of a bioplastics innovation niche as an important sector of the bio-based economy and a viable solution to promote sustainable long-term growth. Relying on the Strategic Niche Management framework, the following niche mechanisms are analysed: (1) convergence of expectations, (2) learning processes, and (3) networking with powerful actors in the sector. We conducted a comparative analysis, looking at Italy and Germany, two frontrunner countries in the bioplastic production who have enacted divergent policies in support of this sector. The comparative perspective has brought some interesting insights into the maturity level of the two respective niches, as well as into the emerging architectural properties of the underling social networks. Core findings show a general high level of expectations in the bioplastics sector in both countries, whereas key elements undermining the niche development refer either to the lack of policy support or to the changing and unstable institutional and regulatory framework. Regarding the architectural structure, the Italian network of actors was largely characterized by an active exchange of knowledge among firms, whereas the German network was characterized by the presence of several institutional actors actively participating in knowledge flows. This last result relates, in the authors' view, to the different policy strategies followed by national governments in the two countries: the German case being characterized by large public investment in R&D, whereas the Italian case is mostly characterized by demand side policies that effectively created a market for bioplastic shoppers. PMID- 30292015 TI - Utilizing of neodymium vanadate nanoparticles as an efficient catalyst to boost the photocatalytic water purification. AB - Neodymium Vanadate (NdVO4) nanostructures were successfully synthesized via a modified solid state method in the presence of ligand. These nanoparticles were further used as a photocatalyst. Primarily the best structural formations and smallest crystallite sizes of the systems were identified and optimized by changing the calcination time, calcination temperature and molar ratio of the ligand. The cationic (Methyl Violet (MV)), and anionic (Eosin Y (EY) and Eriochrome Black T (EBT)) dyes were used as a model to evaluate the photoactivity under UV-Vis irradiation. Several operational factors were examined to improve the photocatalytic efficiency include type of dye, type of light source, pH and dye concentration. As a result, the best efficiency in 5 ppm Eriochorome Black T at pH = 11 was achieved in the presence of 0.05 g NdVO4 nanocatalysts. PMID- 30292016 TI - Urban-centric resilience in search of theoretical stabilisation? A phased thematic and conceptual review. AB - Over the last decades 'resilience' has particularly arisen as an attractive perspective with respect to cities. As cities continue to expand, their susceptibility to uncertainties and new challenges, such as climate change, has increased, rendering 'urban resilience' an increasingly favoured concept in the realm of Urban Development, Planning and Management (UDPM). Despite recent reviews, an updated analysis of the concept is required to understand whether there is in fact scientific evidence to support the expansion and favouring of 'urban resilience' in UDPM. The need to understand how the concept evolved is further emphasised by the need to perceive how the distinct sciences have contributed to its development, and which were the focuses and conceptual underpinnings of such evolution. Thus, the objective of this paper is to provide a broader review of the multidimensional concept of 'urban resilience', while understanding how distinct research fields have contributed to its inception and expansion, and how distinct conceptualisations of resilience have influenced its evolution. Supported by a bibliometric analysis of urban-centric publications, this paper highlights the recent extensive growth and expanding application of 'urban resilience' to distinct research fields, as well as an apparent theoretical stabilisation of the concept, which reemphasises the idea of a three dimensional conceptual resilience perspective in scientific literature: (1) 'engineering', (2) 'ecological', and (3) 'social-ecological resilience'. Consequently, this research emphasises that, if the related conceptual underpinnings are clear, 'urban resilience' can potentially serve as an 'integrative metaphor', adapted by diverse stakeholders, to reinforce UDPM initiatives. PMID- 30292017 TI - Effects of light intensity on biomass, carbohydrate and fatty acid compositions of three different mixed consortia from natural ecological water bodies. AB - This study investigated the effect of light intensity on three various microalga consortia collected from natural ecological water bodies (named A, B and C) towards their fatty acid profiling and fractions, carbohydrate and protein production at different light intensities of 100, 200 and 300 MUmol m-2 s-1. The results indicating that increasing light intensity positively correlated with the lipid production than carbohydrate and protein. Irrespective to the solids (Total and Volatile Solid) content, lipids and carbohydrate has varied significantly. Consortia C showed higher productivity toward lipids, whereas consortia A and B accumulated more carbohydrate and protein, respectively. The microscopic images revealed the breakdown of cells during the increase in light intensity, in spite, the similar algal species were observed in all consortia experimented. Principal component analysis (PCA) revealed that low light intensity aid relatively in high protein, Total Nitrogen and Total Phosphorus, meanwhile high intensity attributed carbohydrates and unsaturated fatty acids (USFA) contents. PMID- 30292018 TI - Study of the effect mechanism of municipal solid waste gasification conditions on the production of H2 and CO using modelling technique. AB - The municipal solid waste (MSW) gasification process was numerically studied in the work. The effect mechanisms of particle size, temperature and gasification atmosphere on the production of H2 and CO were investigated in detail. The results demonstrated that the total volume fraction of H2 and CO dropped from 51.7% to 49.7% with particle size increasing from 20 < d < 30 mm to 80 < d < 100 mm under steam atmosphere. With the temperature increasing from 600 degrees C to 1000 degrees C, the total volume fraction of H2 and CO was raised from 56.1% to 65.8% under steam atmosphere. Five different gasifying agents: 100%CO2, 21%O2/79%N2, 21%O2/79%H2O, 21%CO2/79%H2O, 21%O2/79%CO2 were simulated, and the total volume fraction of H2 and CO was 51.87%, 19.1%, 56.13%, 48.36% and 42.98%, respectively. In the gasification conditions considered in this work, H + H2O<=>OH + H2 (R84) played a key role in the yield of H2, and the yield of CO was significantly affected by H + CO2<=>OH + CO (R99) and H + CH2CO<=>CH3+CO (R81). PMID- 30292019 TI - Effectiveness of pig sludge as organic amendment of different textural class mine tailings with different periods of amendment-contact time. AB - The present study assesses the effect of tailing texture (loamy sand (LT) and sandy loam (ST)), dose of pig sludge (0, 50, 100 and 200 t ha-1) and amendment contact time (14, 28 and 42 days) on physicochemical quality of amended substrate using Lolium perenne var Nui as a bioindicator. The main properties of LT differed of ST in levels of total organic carbon (0.19 and 0.58%), in pH (4.6 and 8.5), total Cu (202 and 1647 mg kg-1) and Zn content (31 and 137 mg kg-1). Soil pore water of experimental substrates was characterized for pH, electrical conductivity (EC) and Cu2+ ion activity (pCu2+) while ammonium nitrogen (NH4+-N), infiltration rate and general physicochemical characteristics were measured in substrates. Shoot biomass (SB), root biomass (RB) and the RB:SB ratio was calculated for L. perenne. The results showed there to be a significant interaction (p < 0.05) between tailing texture, sludge dose and amendment-contact time for pCu2+, infiltration rate, SB, RB, and RB: SB ratio, but not for pH, EC, or NH4+-N. However, sludge dose and amendment-contact time significantly affected all variables. By increasing dosages of pig sludge, pore water pH increased, and this was associated with decreases in pCu2+ and the infiltration rate. High doses of pig sludge (100 and 200 t ha-1) impaired growth of L. perenne irrespective of tailing texture and amendment-contact time, likely because of the rise of EC (up to 14 mS cm-1). For both tailing textures, the highest biomass was obtained after incorporation of 50 t ha-1 of pig sludge, with increasing values as amendment contact time rose. In conclusion, effective management of pig sludge for tailing reclamation should guarantee doses <50 t ha-1 and amendment-contact time >28 days, irrespective of tailing texture. PMID- 30292020 TI - Concurrent Guillain-Barre syndrome, transverse myelitis and encephalitis post Zika: A case report and review of the pathogenic role of multiple arboviral immunity. AB - We review post-infectious and post-vaccination neurological syndromes involving peripheral and central nervous system (CNS) and report an illustrative case of simultaneous occurrence of Guillain-Barre syndrome (GBS), confirmed by nerve conduction velocities, plus MRI-demonstrated transverse myelitis (TM) and acute encephalitis [acute disseminated encephalomyelitis] (ADEM+GBS) affecting a 24 year-old woman from Cucuta, Colombia, who developed acute Zika virus (ZIKV) infection confirmed by serum reverse transcriptase-polymerase chain reaction (RT PCR) and convalescent ZIKV IgG antibodies. With intensive care treatment, respiratory support, steroids, and intravenous immunoglobulin (IVIg), patient survived with residual flaccid paraparesis. She had preexisting immunity against Chikungunya virus (CHIKV) and Dengue virus (DENV) acquired before the arrival of ZIKV in Colombia. From reports in the Caribbean, Central and South America we review 19 cases of ZIKV-associated TM, encephalitis and ADEM occurring after a mean latent period of 10.5 days (range 1-96) post-infection. Although GBS and ADEM are usually considered post-infectious and associated with development of antibodies against peripheral nerve and CNS epitopes, we postulate that our case of ADEM+GBS is para-infectious, induced by acute ZIKV neurotropism boosted by active immunity against other arboviruses. Animal models of ZIKV demonstrated strong viral neurotropism enhanced by passive immunity with antibodies against arboviruses such as West Nile virus, CHIKV, or DENV. These considerations are relevant to prevent potential ZIKV vaccine-induced reactions involving central and peripheral nervous system. PMID- 30292021 TI - Mitochondrial DNA G15927A and G15928A variations in patients with multiple sclerosis. AB - BACKGROUND: Modern genetics has offered a fresh perspective on the pathology of Multiple Sclerosis (MS). As mitochondrial DNA (mtDNA) variations are held to be potential contributors to the complex pathobiology of MS, the present study tests the claim that mtDNA G15927A or G15928A variations, or both, are associated with MS in an Iranian population. MATERIALS AND METHODS: Following DNA extraction from blood samples of 100 subjects with relapsing-remitting MS, and 100 healthy unrelated control subjects, PCR-RFLP analyses was carried out by HpaII restriction enzyme reaction. Electrophoresis was then performed with 3% Agarose gel. As the restriction enzyme did not differentiate between two neighboring nucleotide positions (G15927A and G15928A), all PCR products with a variant allele were sequenced to determine the exact position of the variation. RESULTS: The MtDNA G15927A or G15928A variations were observed in 11 of all 100 cases of MS (11%) and in 7 of 100 healthy control subjects (7%) (P = 0.3, OR = 1.6, 95% CI = 0.5-5.2). Having sequenced all the PCR products with the variant allele (11 cases and 7 controls), the mtDNA G15927A variation was found in one of the 100 cases (1%) and 3 of 100 controls (3%) (P = 0.3, OR = 0.3, 95% CI = 0.0-4.1). Therefore, the mtDNA G15928A variation was present in 10 of the 100 cases (10%) and in 4 of 100 controls (4%) (P = 0.09, OR = 2.6, 95% CI = 0.7-12.0). CONCLUSION: Neither mtDNA variation, G15927A or G15928A, was associated with MS in the studied Iranian population. There was a non-significant association of the G15927A and the G15928A variations separately with MS. PMID- 30292022 TI - An evaluation of suicide prevention hotline results in Taiwan: Caller profiles and the effect on emotional distress and suicide risk. AB - BACKGROUND: Hotlines are among commonly available and recommended suicide prevention strategies in many countries, but only a few empirical studies have focused on people who used this service and the proximal outcomes of calls made to the hotlines. This study is designed to investigate the demographic characteristics of the Taiwan National Suicide Prevention Hotline (NSPH) callers and whether the NSPH service helps to alleviate the callers' emotional distress and suicide risk. METHODS: Descriptive statistics were used to describe the gender, age and county/city distribution of the 63,696 callers from 2009 to 2011. Three hundred telephone records of 100 acute suicidal callers, 100 suicidal callers, and 100 non-suicidal callers were then randomly selected for further investigation of the proximal changes in the callers' emotional disturbance and suicidality. RESULTS: Notwithstanding the suicide status of the callers, significant decreases in their emotional distress and suicidality could be detected during the course of the telephone session. Men, the elderly, and people living outside northern Taiwan, however, were less likely to call the NSPH. An unexpected yet significant finding is that people with an ongoing suicide attempt were less emotionally distressed than those with only suicidal thoughts. CONCLUSIONS: The hotline is a useful suicide preventive and crisis intervention service. However, further creative and consistent work is needed to make the service more appealing to the hard-to-reach population. PMID- 30292023 TI - Correlation between depression/anxiety symptom severity and quality of life in patients with major depressive disorder or bipolar disorder. AB - OBJECTIVE: To study the correlation between depression/anxiety severity and the quality of life (QOL) in patients with major depressive disorder (MDD) or bipolar disorder (BP). METHODS: Two hundred forty-three outpatients diagnosed with MDD or BP were used to study the relationship between depression/anxiety severity and QOL. Depression and anxiety symptom-severity were measured with the QIDS-16-SR (the 16 Item Quick Inventory of Depressive Symptomatology - Self Report), and Zung-SAS (Zung Self-Rating Anxiety Scale). The QOL was measured with the Q-LES-Q short-form (the Quality of Life, Enjoyment and Satisfaction Questionnaire). Correlation was assessed with regression analysis. RESULTS: The percentage of maximum possible scores (MPS) of Q-LES-Q was 72.1%, 70.5%, and 67.6% for euthymic MDD, BPI, and BPII, respectively. Increases in QIDS-16-SR total scores significantly correlated to decreases in Q-LES-Q total scores, with an R2 = 0.61, R2 = 0.52, and R2 = 0.45 for MDD, BPI, and BPII, respectively. Increases in Zung SAS scores also significantly correlated to decreases in Q-LES-Q total scores with an R2 = 0.20, R2 = 0.21, and R2 = 0.12 for MDD, BPI, and BPII. However, after controlling for depression severity, significant differences between Q-LES Q and Zung-SAS scores disappeared in MDD and BP. After controlling for anxiety and other clinical variables, the negative correlation between QIDS-16-SR and Q LES-Q scores remained significant in MDD and BP. CONCLUSIONS: In this outpatient sample, the MPS of Q-LES-Q in euthymic MDD and BP patients was at the lower end of non-psychiatric or medical community norm spectrum. Depression severity was the only independent variable negatively correlated to the QOL in both disorders. PMID- 30292024 TI - Immobilization of phenol-containing molecules on self-assembled monolayers on gold via surface chemistry. AB - Various phenol-containing molecules such as flavonoids have a wide range of biological effects including anticancer, antimicrobial, and anti-inflammatory properties, and, therefore, they have become subjects of active research for various medicinal and biological applications. To construct applicable materials incorporated with phenol-containing molecules, strategies for immobilization of phenol-containing molecules on solid substrates are required. Although several immobilization methods have been devised and reported, mostly harnessing phenol functionality, however, development of a general immobilization method has been hampered due to its complicated chemical reactions and low reaction yields on surfaces. Furthermore, the use of phenol as a reaction center may compromise the biological activity of phenol-containing molecules. Here, we describe a simple, fast, and reliable method for the surface immobilization of phenol-containing molecules by introducing chemical functional groups, carboxylic acid, thiol, and azide, while maintaining phenol functionality by way of the Mannich-type condensation reaction. We examined the chemical functionalization of naphthol, tyrosine, and flavanone and their immobilization to the self-assembled monolayers on gold via various surface chemistries: the carbodiimide coupling reaction, Michael addition, and the 'click' reaction. We strongly believe our method can be a general and practical platform for immobilization of various phenol-containing molecules on surfaces of various materials.

AB - The composite fiber membrane of polyvinyl alcohol (PVA)/sodium alginate (SA)/nano hydroxyapatite (nHAP) was fabricated by electrospinning method. In order to prevent the agglomeration and precipitation of nHAP in aqueous spinning solution, nHAP was ultrasonically suspended in aqueous solution using SA (the component of composite membrane) as stabilizer. The effect of nHAP on the morphology and mechanical property of composite fiber membrane was investigated. The in vitro biological properties including hemolysis, cytotoxicity, cell adhereing and proliferation of composite fiber membrane were evaluated. Results show that SA stabilized nHAP (SA-nHAP) suspension (1.67-10.02 mg/mL) can be obtained with SA/nHAP mass ratio of 1:33.4 for preparing homogeneous spinning solution. The electrospun membranes with PVA/SA/nHAP mass ratio of 9.33:(0.67-0.69):(0-0.668) show good fiber morphology, homogeneous incorporation and distribution of nHAP in fibers, and the content of SA-nHAP (6.25 wt%) in membrane is significantly increased compared to that of untreated nHAP (3.23 wt%). The incorporation of SA nHAP of 1.64 wt.% significantly improves the tensile strength of PVA/SA/nHAP fiber membrane with about 45% enhancement. The hemolysis and cytotoxicity tests show that the composite fiber membrane has good biocompatibility. Moreover, cells can be seeded and proliferate well on composite fiber membrane. Therefore, the obtained PVA/SA/nHAP composite fiber membrane has the potential use as a tissue regeneration material. PMID- 30292026 TI - Fractionated Radiotherapy Is Associated with Lower Rates of Treatment-Related Edema than Stereotactic Radiosurgery in Magnetic Resonance Imaging-Defined Meningiomas. AB - OBJECTIVE: Both stereotactic radiosurgery (SRS) and fractionated radiation therapy (FRT) techniques are used for treatment of intracranial meningiomas with excellent local control (LC) rates. Although SRS techniques are convenient, toxicity including treatment-related edema can significantly impact patient quality of life. The long-term clinical outcomes of patients with magnetic resonance imaging (MRI)-defined meningiomas treated with radiation therapy (RT) alone are reported. METHODS: The charts of 211 patients with meningiomas diagnosed by contrast-enhanced MRI treated with either SRS or FRT between 1991 and 2012 at a single institution were reviewed. Actuarial rates for LC and development of treatment-related radiographic edema (TRE) were determined by the Kaplan-Meier method. RESULTS: There were 211 patients who received radiation therapy for 223 lesions. Median follow-up was 5.7 years. Eleven patients experienced a local failure; of these, 2 were ultimately found to have pathologically proven metastatic carcinoma. Two- and 5-year LC was 97.8% and 94.6%, respectively, with no significant difference based on modality of therapy. Actuarial rate for development of TRE at 1 and 2 years was 30.1% and 34.6% for the SRS group and 1.6% and 2.5% for the FRT group, respectively (P < 0.001). CONCLUSIONS: RT alone using a limited margin is an effective treatment option for MRI-defined meningiomas and should be considered even without biopsy if surgery will present significant morbidity. Although LC with SRS versus FRT was comparable, FRT was associated with a significantly decreased risk of TRE.

PMID- 30292028 TI - Combined Lateral Transpsoas Anterior Column Realignment with Pedicle Subtraction Osteotomy to Treat Severe Sagittal Plane Deformity: Cadaveric Feasibility Study and Early Clinical Experience. AB - BACKGROUND: Traditional open approaches to correct lumbar spine deformities include 3-column osteotomies, such as a pedicle subtraction osteotomy (PSO). Minimally invasive surgical (MIS) techniques have been developed for lateral transpsoas anterior column realignment (ACR). These 2 techniques have not previously been combined. Our objective was to investigate the cadaveric feasibility of a combined hybrid MIS ACR-PSO technique for deformity correction and to review early clinical experience. METHODS: The feasibility of the combined ACR-PSO technique was evaluated in 4 fresh cadaveric specimens. The operative experience, complications, and early clinical outcomes in patients treated with the combined approach to correct global sagittal imbalance were reviewed. RESULTS: In the cadaveric study, the combined ACR-PSO resulted in a mean 46.0 degrees increase in lordosis (P < 0.001). Nine patients treated with ACR-PSO were evaluated (mean age, 65.2 years; 33.3% female). Most patients (6/9; 66.7%) underwent ACR at L1/2 or L3/4; 8 (88.8%) had PSO at L3 or L4. On average, 10.6 +/ 3.8 levels were fused. Significant decreases in mean pelvic tilt (P = 0.01), spinopelvic mismatch (P < 0.001), and T1 spinopelvic inclination (P = 0.03) were observed postoperatively; mean lumbar lordosis (P = 0.007), intradiscal angle (P = 0.001), and thoracic kyphosis (P = 0.04) significantly increased. The overall complication rate was 55.6% (5/9). CONCLUSIONS: Our early experience suggests that a combined ACR-PSO with posterior fixation allows for significant correction of segmental lordosis and global imbalance. This combined approach may maximize results attainable with hybrid MIS-open surgical techniques and represents a complementary option to PSO and other posterior approaches.

PMID- 30292030 TI - Lateral Lumbar Interbody Fusion Revisited: Complication Avoidance and Outcomes with the Mini-Open Approach. AB - OBJECTIVE: To discuss lessons learned from an initial lateral lumbar interbody fusion (LLIF) experience with a focus on evolving surgical technique, complication avoidance, and new motor and sensory outcomes after implementation of a modified surgical approach. METHODS: A retrospective analysis of a prospectively collected series of all patients undergoing LLIF by the senior author (A.D.L.) from January 2010 to January 2018 after implementation of a modified surgical mini-open technique, compared with previously reported institutional results with the originally recommended percutaneous technique. LLIF-specific complications examined included groin/thigh sensory dysfunction, flank bulge/pseudohernia, psoas-pattern weakness, and femoral nerve injury. RESULTS: The incidence (19%, n = 98 patients) of groin/thigh sensory dysfunction in our cohort was significantly lower than that of the historical control (60%, n = 59) (P < 0.0001). The incidence of abdominal flank bulge/pseudohernia (2.0%, n = 98 patients) in our cohort was improved but not significantly lower than that of the historical control (4.2%, n = 118) (P = 0.36). The incidence of psoas pattern weakness (3.1%, n = 98) in our cohort was significantly lower than that of the historical control (23.7%, n = 59) (P = 0.0001). The incidence of femoral nerve injury (0%, n = 98 patients) in our cohort was improved but was not significantly lower than that of the historical control (1.7%, n = 118) (P = 0.20). CONCLUSIONS: The adoption of an exclusive mini-open muscle-splitting approach with first-look inspection of the lumbosacral plexus nerve elements may improve motor and sensory outcomes in general and the incidence of postoperative groin/thigh sensory dysfunction and psoas-pattern weakness in particular.

AB - BACKGROUND: Craniocerebral injuries due to the induction of sharp objects are relatively rare and are nearly always observed in the pediatric rather than the adult population. Orbitocranial injuries involving a piece of smooth steel rod are an extremely rare incident and to our knowledge have yet to be reported in previous literary publications. When this particular category of injury does occur the invading intracranial foreign body usually remains lodged within its entry position. This is most often near the entry point and within the frontal lobe after penetrating the orbit. Migration of the penetrating objects far from the initial entry point is quite rare and has been historically confined to low velocity bullet wounds. CASE DESCRIPTION: An adult male who was injured on the right eyelid by a section of steel rod is presented. The rod had entered the cranium through the right orbital roof and was lodged within the corresponding right frontal lobe. An initial plain radiograph showed that the rod was within the right frontal lobe. However, brain CT angiography performed during the 2nd day of admission demonstrated displacement of the rod to the left hemisphere. This finding was clearly demonstrated through subsequent imaging. As a result of the migration, the rod could be distracted fairly easily via a left parasagittal and interhemispheric approach. Postoperatively, the patient made full recovery. CONCLUSION: Migration of traumatically introduced intracranial foreign bodies far from their initial entry places should be suspected in objects possessing a sufficient weight and a smooth surface. This means that a correct assessment of the final position of such objects is necessary before attempting surgery even while the patient is on the operating table. PMID- 30292034 TI - Determining the Optimal Shape-Related Indicator on Noncontrast Computed Tomography for Predicting Hematoma Expansion in Spontaneous Intracerebral Hemorrhage. AB - OBJECTIVE: Among several novel predictors on noncontrast computed tomography (CT) for hematoma expansion in spontaneous intracerebral hemorrhage (sICH), shape irregularity grade, satellite sign, and island sign are all related to irregular shape of hematoma. This study is aimed to compare the accuracy of these imaging markers for predicting hematoma expansion in the same cohort of sICH patients. METHODS: This retrospective study enrolled sICH patients who underwent diagnostic computed tomography (CT) scans within 6 hours after onset and another follow-up CT scan within 24 hours after initial CT scan. Shape irregularity grade, satellite sign, and island sign were assessed according to the definitions in previous studies. The accuracy of these imaging indicators for predicting hematoma expansion was analyzed using receiver operator analysis. RESULTS: Finally, a total of 196 patients were included. Shape irregularity grade >=3 was found in 87 (44.39%) patients, satellite sign was identified in 76 (38.78%) patients, and island sign was shown in only 41 (20.92%) patients. Only island sign remained an independent predictor for hematoma expansion in multivariate logistic regression. The sensitivity values of shape irregularity grade >=3, satellite sign, and island sign were 0.52, 0.63, and 0.48, respectively. By contrast, the specificity values of these 3 predictors were 0.58, 0.69, and 0.85, respectively. Shape irregularity grade >=3 had the smallest area under the curve (0.597), and island sign had the largest (0.676). CONCLUSIONS: Island sign seems to be the optimal shape-related predictor for hematoma expansion in sICH patients and could be included in the future predictive model for hematoma expansion. PMID- 30292035 TI - Central retinal artery thromboembolism without ophthalmic artery occlusion during stent-assisted coil embolization of an ophthalmic artery aneurysm. AB - BACKGROUND: Recent reports have described that endovascular treatment of coil embolization of ophthalmic artery (OphA) aneurysms has a relative risk of visual disruption caused by thromboembolic infarction of the central retinal artery (CRA), especially the OphA when it originates within the body of the aneurysm. Patent microthrombus in the OphA might also cause retinal infarction that affects visual acuity. We describe stent-assisted coil embolization of an OphA aneurysm complicated with a severe visual disturbance although normal flow was scrupulously maintained in the OphA during the procedure. The visual disturbance was recovered by early treatment. CASE DESCRIPTION: A 40-year-old woman who presented with an intracranial aneurysm arising from the right OphA underwent stent-assisted coil embolization under general anesthesia. Although the area around the origin of the OphA was intentionally avoided and anterograde flow in the OphA was monitored by repeated angiography during this procedure, sight in the right eye was lost immediately thereafter. The immediate application of ocular massage and intra-arterial fibrinolysis improved vision in the right eye to essentially normal status after discharge. CONCLUSIONS: Despite good anterograde flow in the OphA during aneurysm embolization, the procedural risk of a visual disturbance due to thromboembolic complications of CRA occlusion cannot be avoided. Anterograde flow in the OphA and retinochoroidal blush should be monitored by repeated angiography during coil embolization to prevent vision loss. Should vision be lost, a rapid response including ocular massage and intra arterial fibrinolysis is required for recovery. PMID- 30292036 TI - Hemiparesis without responsible hematomas in patients with subarachnoid hemorrhage undergoing early aneurysmal repair. AB - OBJECTIVE: The presence of hemiparesis on arrival in patients with subarachnoid hemorrhage (SAH) is presumed to affect their prognosis, and intracranial hematomas with a mass effect responsible for the hemiparesis are frequently observed in these patients. The purpose of this study was to clarify the characteristics and outcomes of patients who presented with hemiparesis on arrival and showed no responsible hematomas (hemiparesis w/o hematoma) having a mass effect on computed tomography. METHODS: Consecutive SAH patients treated with surgery for ruptured cerebral aneurysms within 5 days of onset between 2003 and 2015 were retrospectively reviewed. RESULTS: Hemiparesis w/o hematoma was present in 25 of 858 surgically treated patients (2.9%). Internal carotid artery (ICA) aneurysms were significantly more common in patients showing hemiparesis w/o hematoma than in the other patients (p<0.05). In 19 of 21 surviving patients (90.5%) with hemiparesis w/o hematoma on arrival, the hemiparesis improved at discharge. Favorable outcomes were achieved in 16 of 25 patients showing hemiparesis w/o hematoma (64%) and in 13 of 59 patients showing hemiparesis with hematomas (22.0%), and the difference was significant (p<0.05). CONCLUSIONS: The hemiparesis could be expected to improve in SAH patients with hemiparesis w/o hematoma, and such patients appear to have a better prognosis than those having SAH with hemiparesis and responsible hematomas. A possible major mechanism of hemiparesis w/o hematoma based on the characteristics identified was a combination of transient ipsilateral hemispheric functional failure caused by the impact of aneurysmal rupture and transient ischemia of the perforators originating from the ICA. PMID- 30292037 TI - Significance and Prognostic Value of The Coagulation Profile in Patients with Glioblastoma: Implications for Personalized Therapy. AB - BACKGROUND: Coagulation is an important aspect of the vascular microenvironment in which brain tumors evolve. Patients with tumor often show aberrant coagulation and fibrinolysis activation. In particular, glioblastoma (GBM), the most aggressive primary brain tumor, is associated with a state of hypercoagulability, and venous thromboembolism is a common complication of this cancer and its treatment. Our study aims to investigate the clinical and prognostic significance of routine laboratory tests to assess the coagulative state of patients with brain tumors, to identify potential new prognostic factors and targets for personalized therapy. METHODS: Blood samples were collected from patients with GBM (n = 58) and patients with meningioma (MNG, n = 22), before any treatment. The parameters analyzed were prothrombin time (PT), activated partial thromboplastin time (aPTT), D dimer (DD), fibrinogen, von Willebrand factor (VWF), leukocyte count, and hemoglobin levels. RESULTS: Plasma levels of PT and aPTT were significantly reduced in GBMs compared with MNGs (P < 0.05), whereas DD, VWF:Ag levels, and leukocyte count were significantly higher in GBMs than in MNGs (P < 0.01). Furthermore, we observed that patients with GBM with reduced PT and aPTT and high levels of DD and VWF, defined as hypercoagulable patients, showed reduced overall survival (P < 0.05) compared with nonhypercoagulable patients. CONCLUSIONS: Our data support the assumption that patients with GBM show a plasma hypercoagulable profile and that coagulation profile is related to adverse outcome in patients with GBM. If confirmed, hypercoagulability could play an important role as a prognostic factor of the disease and in the decision of an antithrombotic prophylaxis. PMID- 30292038 TI - Pituitary Apoplexy following Endoscopic Retrograde Cholangiopancreatography. AB - BACKGROUND: Pituitary apoplexy is an uncommon neurosurgical emergency which may be the initial presentation of undiagnosed pituitary adenomas. Though the exact pathogenesis is unclear, there appears to be an association between pituitary apoplexy and medical interventions which disturb the blood supply and venous drainage of the abnormal sellar region. We present the first case of pituitary apoplexy occurring after an endoscopic retrograde cholangiopancreatography (ERCP). CASE DESCRIPTION: A 43-year-old male who was several hours status post ERCP presented with severe headache, bilateral ptosis and multi-directional ophthalmoplegia. Computed tomography (CT) scan and magnetic resonance imaging (MRI) of the brain revealed a hemorrhagic and necrotic sellar mass with suprasellar extension compressing the optic chiasm and bilateral extension displacing the cavernous carotid arteries laterally. The patient underwent emergent endoscopic transsphenoidal resection of the underlying pituitary tumor apoplexy with eventual resolution of his cranial nerve palsies. CONCLUSIONS: Although pituitary apoplexy has been recognized as a sequela of surgical and laparoscopic procedures, it should also be considered in less invasive gastrointestinal (GI) procedures which may alter the intraabdominal pressures, such as ERCP. Early detection of this unusual complication allows for rapid diagnosis and timely surgical intervention in select cases to prevent debilitating cranial nerve palsies, preserve visual function, and retain normal pituitary function. PMID- 30292039 TI - Minimally Invasive Evacuation of Spontaneous Cerebellar Intracerebral Hemorrhage. AB - OBJECTIVE: Spontaneous cerebellar intracerebral hemorrhage (scICH) constitutes ~10% of all cases of spontaneous ICH, with a mortality of 20%-50%. Suboccipital craniectomy (SOC) is commonly performed for scICH causing brainstem compression or hydrocephalus. However, SOC requires long anesthesia times and results in a high complication rate. We present a series of patients who minimally invasive scICH evacuation as an alternative to traditional SOC. METHODS: We retrospectively reviewed the operative records for patients presenting to a single center from January 1, 2009 to March 1, 2017. All patients who had undergone evacuation of scICH were included in the present study. Clinical and radiographic variables were collected, including admission and postoperative Glasgow coma scale (GCS) scores, preoperative and postoperative hematoma volumes, and modified Rankin scale (mRS) scores at long-term follow-up. RESULTS: We identified 10 patients who had presented with scICH requiring surgery. All scICH evacuations were performed through a minicraniectomy positioned in the suboccipital area as close to the hematoma as possible. The mean patient age was 64.1 years. The mean presenting GCS score was 8.6, the mean initial hematoma volume was 25.4 mL, the mean procedure time was 57 minutes, and the mean postoperative hematoma volume was 2.8 mL. The mortality rate was 10% and mean long-term follow-up mRS score was 2. CONCLUSIONS: Minimally invasive scICH hematoma evacuation is a feasible alternative to SOC with numerous advantages that could lead to improved radiographic and clinical results. PMID- 30292040 TI - Subtotal Resection of Cervical Dumbbell Schwannomas: Radiographic Predictors for Surgical Considerations. AB - OBJECTIVE: Currently, radiologic predictors for the resectability of cervical dumbbell schwannomas remain unknown. To identify radiologic predictors for resectability, we retrospectively reviewed data from 72 patients. METHODS: From January 1995 to June 2017, 72 patients who underwent surgical treatment for cervical dumbbell schwannomas were enrolled. We focused on the relationship between preoperative magnetic resonance imaging (MRI) features and the extent of tumor removal. The MRI features evaluated were tumor size, tumor level, Eden classification, degree of vertebral artery (VA) involvement, and signal intensity (SI) on T2-weighted images (WIs). RESULTS: Among the 72 patients, gross total resection (GTR) and subtotal resection (STR) were achieved in 37 (51.4%) and 35 (48.6%) patients, respectively. Mean maximal tumor size (P = 0.011), mean size of foraminal and extraforaminal portion (P = 0.017), tumor level (P < 0.001), VA involvement (P < 0.001), and SI on T2-WIs (P = 0.006) were significantly different between the GTR and STR groups. Univariate analyses demonstrated that maximal tumor size (odds ratio [OR]: 0.93, P = 0.012), high cervical level (OR: 11.37, P < 0.001), pushed VA (OR: 0.11, P = 0.002), encased VA (OR: 0.02, P < 0.001), and hyper-SI on T2-WIs (OR: 12.46, P = 0.020) were significant predictors for GTR. In the multivariate analysis, only high cervical level (OR: 5.48, P = 0.033) and encased VA (OR: 0.07, P = 0.014) were significant predictors for GTR. CONCLUSIONS: The resectability of cervical dumbbell schwannomas may be predicted by MRI features, including tumor size, tumor level, and degree of VA involvement. PMID- 30292041 TI - Evaluation of Prognosis in Patients with Severe Traumatic Brain Injury Using Resting-State Functional Magnetic Resonance Imaging. AB - BACKGROUND: We investigate the change of the default mode network (DMN) by using amplitude of low-frequency fluctuation (ALFF) and functional connectivity (FC) methods in acute phase patients after severe traumatic brain injury (sTBI) and correlate these changes with prognosis. METHODS: Twenty-one patients with sTBI were included. Twenty-one healthy sex-, age-, and education-matched control subjects were recruited for the control group. Of the 21 patients with sTBI, 12 patients regained consciousness (Glasgow Outcome Scale [GOS] score >2) and 9 patients remained unconscious (GOS score <2). FC and ALFF values were measured in the DMN and compared between the groups. We further assessed and compared the FC and ALFF values in both groups. RESULTS: Patients with sTBI showed significantly decreased FC and ALFF values in the DMN. However, patients with a better prognosis showed a significant increase in FC and ALFF values in the DMN. The conscious subgroup showed significantly enhanced FC in the medial superior frontal gyrus, left temporal gyrus, anterior cingulate gyrus, precuneus, posterior cingulate gyrus, and parietal cortex compared with the coma subgroup. Increased ALFF values in the right frontal gyrus, right temporal gyrus, and right inferior parietal gyrus were significant in the conscious subgroup compared with the coma subgroup. CONCLUSIONS: Increases in FC and ALFF values in the DMN are related to better prognosis in patients with sTBI. PMID- 30292043 TI - Present Role of Surgery for Brain Metastases.

PMID- 30292044 TI - Elucidating the effects of different photoanode materials on electricity generation and dye degradation in a sustainable hybrid system of photocatalytic fuel cell and peroxi-coagulation process. AB - The hybrid system of photocatalytic fuel cell - peroxi-coagulation (PFC-PC) is a sustainable and green technology to degrade organic pollutants and generate electricity simultaneously. In this study, three different types of photocatalysts: TiO2, ZnO and alpha-Fe2O3 were immobilized respectively on carbon cloth (CC), and applied as photoanodes in the photocatalytic fuel cell of this hybrid system. Photocatalytic fuel cell was employed to drive a peroxi coagulation process by generating the external voltage accompanying with degrading organic pollutants under UV light irradiation. The degradation efficiency of Amaranth dye and power output in the hybrid system of PFC-PC were evaluated by applying different photoanode materials fabricated in this study. In addition, the effect of light on the photocurrent of three different photoanode materials was investigated. In the absence of light, the reduction of photocurrent percentage was found to be 69.7%, 17.3% and 93.2% in TiO2/CC, ZnO/CC and alpha-Fe2O3/CC photoanodes, respectively. A maximum power density (1.17 mWcm 2) and degradation of dye (93.8%) at PFC reactor were achieved by using ZnO/CC as photoanode. However, the different photoanode materials at PFC showed insignificant difference in dye degradation trend in the PC reactor. Meanwhile, the degradation trend of Amaranth at PFC reactor was influenced by the recombination rate, electron mobility and band gap energy of photocatalyst among different photoanode materials. PMID- 30292045 TI - A comparison study of in-situ coagulation and magnetic ion exchange (MIEX) as pre treatments for ultrafiltration: Evaluating effectiveness of organic matters removals and fouling mitigation. AB - This work was designed to compare the effectiveness of in-situ coagulation and MIEX as pre-treatments prior to ultrafiltration (UF) to improve organic matter (OM) removal and mitigate membrane fouling. Three kinds of OMs, i.e. salicylic acid (SA), humic acid (HA) and bovine serum albumin (BSA) were employed. The experimental results show that coagulation-UF led to most effective removal of HA (almost 90%), while the SA was uncoagulated and least removable, with the rejection rate of about 55%. Conversely, MIEX present superior ability for removing SA, contributing to additional efficiency of 71.95-77.21% than UF alone. Proper dosage of Al-based coagulants could alleviate flux loss, especially in the cases of HA and BSA. Increasing coagulant dose resulted in continuous decrement of irreversible resistance (Rir), which dominated the membrane fouling development by the SA water. For HA and BSA waters, alternatively, variations of Rr determined the flux declines. Floc compact degree was the decisive factor for Rr for coagulated SA; while for HA and BSA, Rr was most related to the floc size and foulant-foulant interaction. MIEX was most effective for alleviating flux loss when treating the hydrophilic SA with small molecules and for all the cases, MIEX exerted little influence on the Rr values. PMID- 30292046 TI - Efficient degradation of Orange G with persulfate activated by recyclable FeMoO4. AB - In this study, FeMoO4 was applied to activate persulfate (PS, S2O82-) for azo dye Orange G (OG) degradation. The catalyst was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS) and nitrogen adsorption-desorption isotherms. FeMoO4 showed excellent efficiency in activating PS for OG removal. More than 95% could be removed after 40 min under reaction conditions of 4 mM PS, 0.3 g L-1 FeMoO4 and 0.2 mM OG. The effect of different parameters (PS doses, FeMoO4 doses and pH) were evaluated. The results showed that acid condition provided higher efficiency and overdosing FeMoO4 and PS presented a scavenging effect. Major intermediates were identified and possible degradation pathway was proposed. Recycle tests presented that FeMoO4 had excellent recyclable stability in activating PS for OG removal. Sulfate radicals and hydroxyl radicals all occurred in the oxidation reactions and the former came first. The oxidation reaction was involved in the translation of Fe2+/Fe3+ occurred on the surface layer. This study revealed that the FeMoO4/PS system is a very promising method for degrading organic contaminants in the environment. PMID- 30292047 TI - Exposure to triclosan changes the expression of microRNA in male juvenile zebrafish (Danio rerio). AB - Triclosan (TCS) is a broad-spectrum antibacterial agent which is widely used in various personal care products and cosmetics. It has been found that TCS affects endocrine, immune, nervous, reproductive, and developmental system. Although microRNAs (miRNAs) act a pivotal part in lots of metabolic activities, whether and how they are related to the process of TCS-induced toxicity is unknown. In the present study, TCS induced changes in miRNAs and target gene expression in male zebrafish (Danio rerio) brain, and the potential mechanism was studied. Male juvenile zebrafish were exposed to 0 and 68 MUg/L TCS for 42 d. miRNA was isolated from the brain pool of the zebrafish and the expression profiles of 255 known zebrafish miRNAs were analysed by using Affymetrix miRNA 4.0 microarrays. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to assay the expression of 5 differentially expressed miRNAs in the microarray data and some related-genes in brains. The GO term analysis revealed that miRNAs significantly affected by TCS exposure were mainly involved in translation, transcription, DNA templated, protein transport, and motor neuron axon guidance biological process. Pathway analysis showed that target genes of 5 differentially expressed miRNAs prominently participate in basal transcription factors, purine metabolism, and ribosome biogenesis in eukaryotes. In addition, key genes in purine metabolism pathway and oxidative stress related-genes were significantly changed. These findings offer novel insight into the mechanisms of epigenetic regulation in TCS induced toxicity in male zebrafish, and distinguish novel miRNA biomarkers for exposure to TCS. PMID- 30292048 TI - Bioremediation of soils contaminated by PAHs: Mutagenicity as a tool to validate environmental quality. AB - Bioremediation can be used as one of the decontamination techniques for areas contamined by polycyclic aromatic hydrocarbons (PAHs). However the effective biodegradation of these compounds must take into account the possible toxic and mutagenic effects that might persist. In this study the mutagenic potential of soil samples from an area contaminated by wood preservatives was evaluated. The area had already been submitted to a simulated bioremediation process in a microcosm, using two different inoculums (1 and 2), and comparing them to the decay of PAHs. Organic extracts were prepared before and after bioremediation, where the 16 PAHs considered a priority by USEPA were analyzed and tested using the Salmonella/microsome assay. The extracts were analyzed in strains TA98, TA97a and TA100 (+S9mix/-S9mix), YG1041 and YG1042. Considering Inoculum 1 only as bioaugmented and Inoculum 2 also stimulated and enriched, the concentrations of PAHs and mutagenic effect were different. The former identified a greater reduction of mutagenesis and a smaller decrease of PAHs while the latter showed greater mutagenic power even associated with the greatest reduction of PAHS. The possible generation of degradation byproducts with high mutagenic power after a partial biodegradation process can be considered. In strains YG1041 and YG 1042 the mutagenesis values before bioremediation were 747 and 567 rev/g soil, respectively. Although the efficiency of bioremediation was observed, the associated damage indicates that the analysis of contaminants and their relationship with mutagenic effects are a fundamental stage for the effective evaluation of the risks and efficiency of bioremediation processes. PMID- 30292049 TI - Combined photoelectrocatalytic microbial fuel cell (PEC-MFC) degradation of refractory organic pollutants and in-situ electricity utilization. AB - A new photoelectrocatalytic (PEC) and microbial fuel cell (MFC) process was developed and applied to simultaneously remove refractory organic pollutants (i.e., phenol and aniline) from wastewater while recovering energy for in-situ utilization. The current generated by the MFC process was applied to drive the PEC reaction. Compared with single PEC or MFC processes, the PEC-MFC combined process showed higher pollutant and chemical oxygen demand (COD) removal capacities and electricity production. Over 95% of the phenol or aniline was removed by these process, even at high initial concentrations. The COD removal efficiencies for phenol and aniline were ca. 96% (from 700 to 29 mg L-1) and 70% (from 165 to 49 mg L-1), respectively. Although the PEC process showed a limited contribution to phenol and aniline removals (16.5% and 43%, respectively), the utilization of PEC-treated phenol or aniline streams resulted in a MFC with higher voltage output, higher coulombic efficiency, maximal volumetric power density, and lower internal resistance as compared to untreated water. High performance liquid chromatography coupled with mass spectrometry measurements revealed quinones/hydroquinones and low molecular weight organic acids to be produced as intermediates after the PEC process, which could improve the production of electricity in the MFC. PMID- 30292050 TI - Investigation of toxicological effects of amorphous silica nanostructures with amine-functionalized surfaces on Vero cells. AB - Amorphous silica (SiO2) nanostructures are described in the literature as having low toxicity and are widely used in many industrial products. However, surface modifications, such as amine-functionalization, can result in increased cytotoxicity. In this study, amorphous SiO2 nanostructures (SiO2 NS) were synthesized and amine-functionalized with two different amine molecules: primary (SiO2 NS@1) and tri-amine (SiO2 NS@3). The materials were characterized by transmission electron microscopy (TEM), zeta potential (ZP), effective diameter (ED) and surface area measurements, X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The toxicity of the three SiO2 NS samples toward Vero cells was evaluated. According to the methyl thiazolyl tetrazolium (MTT) assay, the IC50,24h was 1.477 +/- 0.12 g L-1 for SiO2 NS, 0.254 +/- 0.07 g L-1 for SiO2 NS@1 and 0.117 +/- 0.05 g L-1 for SiO2 NS@3. The order of cytotoxicity was SiO2 NS@3 > SiO2 NS@1 " SiO2 NS. There was an increase in malondialdehyde (MDA) levels and ROS productions in the cells exposed to all three materials. Also, TEM images showed damage on the mitochondria and rough endoplasmic reticulum. PMID- 30292051 TI - Interactions between microplastics and phthalate esters as affected by microplastics characteristics and solution chemistry. AB - Microplastics have become a major concern in recent years as they can be recognized as the transport vectors for pollutants in environment. In this study, the sorption behavior of two phthalate esters (PAEs), including diethyl phthalate (DEP) and dibutyl phthalate (DBP), onto three types of microplastics (PVC: polyvinyl chloride, PE: polyethylene, and PS: polystyrene) was investigated. The sorption isotherms of both DEP and DBP on microplastics were highly linear, suggesting that the partition was the main sorption mechanism. The Kd values of DBP were much higher than those of DEP, demonstrating that hydrophobic interaction governed the partition mechanism. Sorption of the two PAEs on the three microplastics followed the order of PS > PE > PVC, indicating that chemical properties of microplastics played an important roles in their sorption behaviors. Solution pH and natural organic matter had no significant impact on PAEs sorption by microplastics. However, the presence of NaCl and CaCl2 enhanced the sorption of both DEP and DBP because of the salting-out effect. The findings of the present study may have significant implications for the fate and transport assessment of both PAEs and microplastics. PMID- 30292052 TI - Rotating packed bed as a novel disinfection contactor for the inactivation of E. coli by ozone. AB - The intensification of mass transfer and mixing in ozone-based disinfection processes is very important in order to achieve a certain disinfection effect at a reasonable cost. This study employed rotating packed bed (RPB), an efficient process intensification device, as an ozone-disinfection contactor, and its performance on disinfection and mass transfer was evaluated by the inactivation of Escherichia coli (E. coli) and mass transfer coefficient (kLa). The ozone exposure (Ct value) and the log inactivation of E. coli in the RPB reached 0.0008 0.0014 min mg L-1 and 6.8-7.3 in phosphate buffered saline buffer, respectively. And the kLa in RPB rose from 0.030 to 0.186 s-1 with the increase of liquid flow rate from 10 to 60 L h-1. The increase of rotation speed of the RPB enhanced the log inactivation and kLa simultaneously. It was also noted that a higher gaseous ozone concentration at the identical applied ozone dosage is favorable for the inactivation of E. coli. The calculation of Hatta number indicated that the inactivation of E. coli in RPB is a diffusion-controlled process for which RPB is well suited. Compared to the conventional bubble reactor, the achievement of high disinfection efficacy at a low Ct value in RPB revealed that RPB is an efficient ozone disinfection contactor for the inactivation of microorganisms in water. PMID- 30292053 TI - Myocardial infarction after epilepsy onset: A population-based retrospective cohort study. AB - INTRODUCTION: Cardiovascular comorbidities of epilepsy such as hypertension, hyperlipidemia, and diabetes are associated with myocardial infarction (MI). Little data on the development of subsequent cardiovascular disease (CVD) in persons with epilepsy (PWE) are available, with inconsistent findings regarding the association between epilepsy and subsequent MI. A higher risk of MI among adults (without prior MI) following epilepsy diagnosis compared with that among controls was hypothesized. METHODS: This retrospective cohort study used statewide hospital and emergency department (ED) encounter data from 2000-2013 for South Carolina residents aged >18 years without prior MI at the onset of epilepsy, or the first encounter for controls. Persons with epilepsy were compared with 1) persons with migraine (PWM), whose neurological condition has characteristics similar to epilepsy; and 2) persons with isolated lower extremity fracture (PWLF). Subsequent MI was defined as a diagnosis of MI after the first clinical encounter for epilepsy, migraine, or lower extremity fracture (LEF); the association was evaluated with Cox proportional hazard modeling methods. RESULTS: In this study, 2.2% of PWE, 0.6% of PWM, and 1.2% of PWLF had a subsequent MI. Persons with epilepsy were significantly more likely to be non-Hispanic Black (NHB), be covered by Medicaid, and reside in a rural or low income area compared with PWM and PWLF. Specific cardiovascular disease risk factors were more prevalent in PWE than in PWM and PWLF. After adjustment, the hazard of subsequent MI in PWE was 48% higher than in PWM (hazard ratio (HR) = 1.48; 95% confidence intervals (CI) = 1.31-1.67) and 24% higher than in PWLF (HR = 1.24; 95% CI = 1.10 1.39). The hazard of MI increased with increasing age and number of additional comorbidities and was higher in males, those living in rural areas, and those with specific cardiovascular risk factors. CONCLUSION: Persons with epilepsy had moderately elevated risk of subsequent MI compared with PWM or PWLF. The association between epilepsy and MI needs to be further investigated, and clinical care of PWE should include evaluation and management of risk factors for MI. PMID- 30292054 TI - Automated quantification of EEG spikes and spike clusters as a new read out in Theiler's virus mouse model of encephalitis-induced epilepsy. AB - Intracerebral infection of C57BL/6 mice with Theiler's murine encephalomyelitis virus (TMEV) replicates many features of viral encephalitis-induced epilepsy in humans, including neuroinflammation, early (insult-associated) and late (spontaneous) seizures, neurodegeneration in the hippocampus, and cognitive and behavioral alterations. Thus, this model may be ideally suited to study mechanisms involved in encephalitis-induced epilepsy as potential targets for epilepsy prevention. However, spontaneous recurrent seizures (SRS) occur too infrequently to be useful as a biomarker of epilepsy, e.g., for drug studies. This prompted us to evaluate whether epileptiform spikes or spike clusters in the cortical electroencephalogram (EEG) may be a useful surrogate of epilepsy in this model. For this purpose, we developed an algorithm that allows efficient and large-scale EEG analysis of early and late seizures, spikes, and spike clusters in the EEG. While 77% of the infected mice exhibited early seizures, late seizures were only observed in 33% of the animals. The clinical characteristics of early and late seizures did not differ except that late generalized convulsive (stage 5) seizures were significantly longer than early stage 5 seizures. Furthermore, the frequency of SRS was much lower than the frequency of early seizures. Continuous (24/7) video-EEG monitoring over several months following infection indicated that the latent period to onset of SRS was 61 (range 16-91) days. Spike and spike clusters were significantly more frequent in infected mice with late seizures than in infected mice without seizures or in mock-infected sham controls. Based on the results of this study, increases in EEG spikes and spike clusters in groups of infected mice may be used as a new readout for studies on antiepileptogenic or disease-modifying drug effects in this model, because the significant increase in average spike counts in mice with late seizures obviously indicates a proepileptogenic alteration. PMID- 30292055 TI - The rise and fall of the alveolar process: Dependency of teeth and metabolic aspects. AB - The alveolar bone has a unique capacity to follow the teeth's movements. It is formed around erupting teeth and their periodontal ligaments: the more the teeth have erupted, the larger the alveolar process. Throughout life the teeth erupt and migrate in an occlusal and mesial direction to compensate for attrition, an evolutionary trait. After tooth extraction, the alveolar process is resorbed to varying degrees. The mandibular alveolar bone mirrors skeletal bone condition. Due to fast bone turnover (which is the fastest in the whole skeleton), low bone mass and increased fracture risk may first be seen here. If a periapical radiograph of the mandibular premolars shows a dense trabeculation with well mineralized trabeculae and small intertrabecular spaces, it is a reliable sign of normal skeletal bone density (BMD) and low skeletal fracture risk, whereas a sparse trabecular pattern indicates osteopenia and high fracture risk. The bone turnover rate in the mandible is twice that of the maxilla, and may, hypothetically, play a role in the development of osteonecrosis of the jaw (ONJ), which has been found mainly in the mandibular alveolar process?

AB - Methylisothiazolinone (MI) is a preservative used in consumer products to control bacterial and fungal growth. MI can be toxic, act as a skin sensitizer and irritant, and initiate lung diseases; therefore, it is important to understand the mechanisms underlying the toxicity of MI in the body. In this study, we developed a method to analyze plasma MI by using an LC-MS/MS-coupled multiple reaction monitoring (MRM) technique, which follows the fragments of a target metabolite in rat plasma. The MRM transition of MI was m/z 116 ? 101, and the lower limit of quantification (LLOQ) was set at 10 ng/mL. Including the concentration of LLOQ, a seven-point calibration curve explained much of the variation in the response, and it was strongly linear (R2 = 0.9998); its intra- and inter-day accuracy and precision values were within 15% of the standard deviation (SD%) and along with the FDA and Korea Ministry of Food and Drug Safety guidelines. For intravenous (iv) pharmacokinetic studies of MI using rats, we developed an analytical method that was useful in detecting the profile of MI in the plasma. We also determined half-life, and area under the curve (AUC) of MI using a non-compartment model, and these might be useful for the study of toxic mechanisms of MI in the body. PMID- 30292057 TI - Novel zwitterionic HILIC stationary phase for the determination of ethyl glucuronide in human hair by LC-MS/MS. AB - Some recent studies have described a shift from traditional reversed-phase to more hydrophilic LC chemistry for EtG determination in hair (hEtG). The reason relies on the poor retention of C8- and C18-based columns for polar compounds, even in presence of great amount of aqueous phase. This work presents the development, validation and application of a new hydrophilic interaction liquid chromatography-tandem mass spectrometry (HILIC-LC-MS/MS) method based on a novel zwitterionic stationary phase for the analysis of hEtG. The linearity was assessed in the range of 5-100 pg/mg hair, with a correlation coefficient of >0.99. The method was selective and sensitive, with a limit of detection (LOD) and limit of quantitation (LOQ) of 1.4 pg/mg and 4.5 pg/mg in hair, respectively. Suitable diagnostic sensitivity was achieved without the introduction of a sample purification step, or a post column solvent addition. The method was successfully applied to real hair samples after full validation. This method, based on a separation at neutral conditions, confirmed the optimum retention and thus selectivity for weak acids in zwitterionic HILIC columns. PMID- 30292058 TI - Type-I counter-current chromatography with the multilayer coil for protein separation. AB - In our recent study, the design and performance of type-I counter-current chromatography (CCC) were changed and improved by multilayer coil. In the present study, the performance of protein separation using the multilayer coil configuration in type-I CCC was investigated under various flow rates. In order to overcome the noise signal interrupting the target peaks, a hollow fiber membrane dialyzer was inserted between CCC column outlet and inlet of the monitor. The separation was performed with a two-phase solvent system composed of polyethylene glycol 1000/dibasic potassium phosphate each at 12.5% (w/w) in deionized water and lysozyme and myoglobin were used as the test samples. The retention of stationary phase in the head to tail elution mode was lower than that in the tail to head elution mode, but Rs (peak resolution) was opposite. The intermittently pressed tubing can efficiently improve the performance of protein separation by type-I CCC with the multilayer coil. The best Rs was 1.54 and obtained at the flow rate of 0.10 ml/min under a revolution speed of 200 rpm. The present result indicated that type-I CCC can be as a potential powerful tool of protein separation for the first time. PMID- 30292059 TI - Using simulation to help beginning nursing students learn about the experience of poverty: A descriptive study. AB - BACKGROUND: Increased numbers of individuals and families in the United States are living below the poverty level. Beginning nursing students must start to develop an understanding of the constraints of living in poverty and its relationship with health. OBJECTIVES: To describe the effects of a poverty simulation implemented in a freshman-level course as a beginning preparation for working with patients who face financial hardship. DESIGN: Descriptive study with a pre-test and post-test design. SETTING: School of Nursing within a private, religiously-affiliated university in the northeastern United States. PARTICIPANTS: 170 freshman-level Bachelor of Science in Nursing (BSN) students. METHODS: Students participated in a poverty simulation designed to sensitize participants to the experience and realities of living in a typical low-income family. Using the Undergraduate Perceptions of Poverty Tracking Survey, data were collected on students' general attitudes toward poverty, empathy for those living in poverty, and commitment to addressing poverty, two weeks prior to and one week after the poverty simulation experience. RESULTS: A significant decrease was noted in total scores from pre-simulation to post-simulation with a mean decrease of 7.9 +/- 10.1 points (+/-standard deviation), p < .001. Significant decreases were also noted in four of the six subscales, including the Welfare Attitudes, Poor are Different, Equal Opportunity and Lack of Resources subscales, ps < .001. Changes represent improvements in the students' attitudes toward poverty, empathy for those faced with poverty, and recognition of societal and structural barriers encountered by individuals living in poverty. CONCLUSIONS: This poverty simulation contributed to building empathy among freshman, BSN students and preparing them, early on, to provide more sensitive care to economically disadvantaged populations. Nursing programs should include similar learning experiences at the beginning of curricula, so that this knowledge becomes an integral part of the care students provide throughout their clinical experiences. PMID- 30292060 TI - Validation of Mentors' Behavior Scale among mentors. AB - BACKGROUND: The Mentors' Behavior Scale was developed and validated initially among nursing students by assessing the importance of mentors' behavior, showing satisfactory psychometrics and the potential to match mentors with students according to students' expectation. OBJECTIVES: This study aims to test the discriminant validity and the structure of the Mentor's Behavior Scale among mentors to assess mentors' performance. DESIGN: A cross-sectional survey was applied in the study. SETTING: Data were collected from mentors in seven hospitals in north, south, southwest China in 2016 and 2017. PARTICIPANT: 871 mentors participated in this study. METHODS: Purposeful sampling and online survey was used. RESULTS: Three factors (to guide personal growth, promote professional development, and provide psychosocial support) were identified by exploratory factor analysis. The cumulative contribution of variance was 61.03%. The Cronbach's alpha coefficient of the scale was 0.85, and those of the three subscale's were 0.84, 0.72, and 0.74. The results of discriminant validity showed that mentors who received training and who liked mentoring students scored higher in mentoring behavior. CONCLUSION: Mentors considered that mentoring behavior were to guide students' personal growth, promote professional development and provide them with psychosocial support. It will be useful to apply The Mentors' Behavior Scale among mentors to guide and evaluate their behaviors. PMID- 30292061 TI - Biomechanical evaluation of the first ray in pre-/post-operative hallux valgus: A comparative study. AB - BACKGROUND: Deformity of the first ray in hallux valgus patient has been deemed to mainly contribute to instability of the metatarsophalangeal joint. However, it is not clear whether the fixation of the distal osteotomy fragment and transposition of the sesamoid represent the best method for hallux valgus treatment. The aim of this study was to examine how postoperative hallux valgus osteotomy affects the stability of the first ray. METHODS: To accurately investigate the biomechanical behavior of the first ray in pre-/postoperative hallux valgus patients, we described the relative displacement and stress distribution of the first metatarsal bone and sesamoid by imageology, test measurement and foot finite element model. FINDINGS: Compared with the preoperative hallux valgus, the plantar pressure decreased by 47.8% and was redistributed on second metatarsal region. The peak stress and relative displacement of the distal osteotomy fragment increased by +55.7% and -59.9%, respectively. The movement of this component shifted toward the positive sagittal axis direction. In addition, the relative displacement of sesamoid decreased by 87.4% (0.18 mm) in vertical axis direction and the stress was also redistributed on medial and lateral region. Moreover, the strain of the medial main ligament was more favorable to reconstruct function of the first ray. INTERPRETATION: The findings showed that the osteotomy method was helpful for stability of the first ray. This would provide the stability suggestions for postoperative hallux valgus fixation and guide further rehabilitation. PMID- 30292062 TI - Lesser lower extremity mechanical loading associates with a greater increase in serum cartilage oligomeric matrix protein following walking in individuals with anterior cruciate ligament reconstruction. AB - BACKGROUND: Aberrant mechanical loading during gait is hypothesized to contribute to the development of posttraumatic osteoarthritis following anterior cruciate ligament reconstruction. Our purpose was to determine if peak vertical ground reaction force and instantaneous vertical ground reaction force loading rate associate with the acute change in serum cartilage oligomeric matrix protein following a 20-minute bout of walking. METHODS: We enrolled thirty individuals with a unilateral anterior cruciate ligament reconstruction. Peak vertical ground reaction force and instantaneous vertical ground reaction force loading rate were extracted from the first 50% of the stance phase of gait during a 60-second trial. Blood samples were collected immediately before and after 20 min of treadmill walking at self-selected speed. The change in serum cartilage oligomeric matrix protein from pre- to post-walking was calculated. Stepwise linear regression models were used to determine the association between each outcome of loading and the change in serum cartilage oligomeric matrix protein after accounting for sex, gait speed, time since anterior cruciate ligament reconstruction, graft type, and history of concomitant meniscal procedure (DeltaR2). FINDINGS: Lesser peak vertical ground reaction force (DeltaR2 = 0.208; beta = -0.561; P = 0.019) and instantaneous vertical ground reaction force loading rate (DeltaR2 = 0.168; beta = -0.519; P = 0.037) on the anterior cruciate ligament reconstructed limb associated with a greater increase in serum cartilage oligomeric matrix protein following 20 min of walking. INTERPRETATION: Mechanical loading may be a future therapeutic target for altering the acute biochemical response to walking in individuals with an anterior cruciate ligament reconstruction. PMID- 30292063 TI - Contact force between the tibial spine and medial femoral condyle: A biomechanical study. AB - BACKGROUND: Contact between the tibial spine and medial femoral condyle with internal tibial rotation (ITR) has been proposed as a factor for the development of osteochondritis dissecans lesions. We hypothesized that tibial spine contact force (CF) would increase significantly with applied internal tibial torque (IT). METHODS: A 20 mm diameter cylinder of bone encompassing the tibial spine was cored and attached to a load cell. The isolated bone cylinder included the tibial attachments of the anterior cruciate ligament (ACL) and anterior horn of the lateral meniscus (AHLM). Eleven human cadaveric knees were flexed from 0 degrees 50 degrees under 200 N of tibiofemoral compression (TFC), without and with 2 N-m IT. Tests were repeated with the AHLM cut, and again with both AHLM and ACL cut, where the load cell recorded CF alone without contributions from any ligamentous attachments. FINDINGS: There were no significant differences in CF, ITR, or valgus tibial rotation (VTR) after sectioning the AHLM, without or with applied IT. With no tibial torque, mean CFs were less than 20 N throughout the flexion range. Addition of IT significantly increased 1) mean CF by 44.4 N(SD 15.8 N) at 0 degrees (+240%) and 27.2 N(SD 5.0 N) at 20 degrees (+675%), 2), mean ITR by 10.2 degrees (SD 0.8 degrees ) at 0 degrees flexion and 18.6 degrees (SD 2.0 degrees ) at 20 degrees flexion, and 3) mean VTR by 1.3 degrees (SD 0.4 degrees ) at 0 degrees flexion and 4.4 degrees (SD 0.8 degrees ) at 20 degrees flexion. INTERPRETATION: Our hypothesis was confirmed only between 0 degrees and 20 degrees of knee flexion, where the intercondylar separation distance is relatively small and the possibility of tibial spine contact with ITR is greater. PMID- 30292064 TI - Phenotype of vigilin expressing breast cancer cells binding to the 69 nt 3'UTR element in CSF-1R mRNA. AB - Vigilin, a nucleocytoplasmic shuttling protein, post-transcriptionally suppresses proto-oncogene c-fms expression (encoding CSF-1R) in breast cancer by binding to a 69 nt cis-acting 3-UTR element in CSF-1R mRNA. CSF-1R is an important mediator of breast cancer development, metastasis, and survival. We confirm that vigilin decreases in vitro reporter luciferase activity as well as the translation rate of target mRNAs. We further explore the mechanism of suppression of CSF-1R. We show that the 69 nt binding element has profound effects on translation efficiency of CSF-1R mRNA, not seen in the presence of mutation of the element. Also, mutation of the 69 nt element in the CSF-1R mRNA 3'UTR both interferes with direct vigilin binding and obviates effect of vigilin overexpression on translational repression of CSF-1R. We show that stable vigilin binding requires the full length 69 nt CSF-1R element, including the 26 nt pyrimidine-rich core. Furthermore, titration of endogenous vigilin and other proteins which bind the 69 nt element, by exogenously introduced CSF-1R mRNA 3'UTR containing the pyrimidine rich sequence, increases the adhesion, motility, and invasion of breast cancer cells. This phenotypic effect is not seen when the 69 nt element is deleted. Lastly, we are the first to show that human breast tissues exhibit strong vigilin expression in normal breast epithelium. Our pilot data suggest decreased vigilin protein expression, along with shift from the nucleus to the cytoplasmic location, in the transition to ductal carcinoma in situ. PMID- 30292065 TI - Phenotypic and Expressional Heterogeneity in the Invasive Glioma Cells. AB - BACKGROUND: Tumor cell invasion is a hallmark of glioblastoma (GBM) and a major contributing factor for treatment failure, tumor recurrence, and the poor prognosis of GBM. Despite this, our understanding of the molecular machinery that drives invasion is limited. METHODS: Time-lapse imaging of patient-derived GBM cell invasion in a 3D collagen gel matrix, analysis of both the cellular invasive phenotype and single cell invasion pattern with microarray expression profiling. RESULTS: GBM invasion was maintained in a simplified 3D-milieue. Invasion was promoted by the presence of the tumorsphere graft. In the absence of this, the directed migration of cells subsided. The strength of the pro-invasive repulsive signaling was specific for a given patient-derived culture. In the highly invasive GBM cultures, the majority of cells had a neural progenitor-like phenotype, while the less invasive cultures had a higher diversity in cellular phenotypes. Microarray expression analysis of the non-invasive cells from the tumor core displayed a higher GFAP expression and a signature of genes containing VEGFA, hypoxia and chemo-repulsive signals. Cells of the invasive front expressed higher levels of CTGF, TNFRSF12A and genes involved in cell survival, migration and cell cycle pathways. A mesenchymal gene signature was associated with increased invasion. CONCLUSION: The GBM tumorsphere core promoted invasion, and the invasive front was dominated by a phenotypically defined cell population expressing genes regulating traits found in aggressive cancers. The detected cellular heterogeneity and transcriptional differences between the highly invasive and core cells identifies potential targets for manipulation of GBM invasion. PMID- 30292067 TI - Pediatric oral Epstein-Barr virus associated self-remitting CD30+ lymphoproliferative disorder: A distinct entity. AB - Epstein-Barr virus (EBV) has a well-known association with lymphoproliferative disorders of B and T cell origin. EBV-related B cell lymphoproliferative disorders include Hodgkin and Burkitt lymphomas, lymphomatoid granulomatosis, EBV positive diffuse large cell B cell lymphoma of the elderly, as well as B cell lymphomas associated with solid organ transplantation and methotrexate use. EBV related T cell disorders are primarily represented by NK/T- cell lymphoma. In a subset of patients, EBV has been implicated in CD30 positive B cell lymphoproliferative disorders of the oral mucosa falling under the rubric of the mucocutaneous ulcer of the oral cavity. We previously reported on an index series of endogenous CD30 positive T cell lymphoproliferative disorder of the oral cavity resembling borderline type C lymphomatoid papulosis. The clinical manifestation of type C oral lymphomatoid papulosis is that of a recurrent self remitting ulcer of the oral mucosa, which histologically resembles anaplastic large cell lymphoma. Such cases can be misdiagnosed as aggressive lymphoma leading to unnecessary treatment with aggressive chemotherapeutic regimens. Whereas none of the patients in our index series exhibited EBV positivity, here we discuss a very unique example of a 14-year-old girl diagnosed with EBV positive CD30 positive lymphoproliferative disorder strongly resembling the cases of intra-oral type C lymphomatoid papulosis. The patient was initially diagnosed by a senior hematopathology consultant as having EBV positive aggressive NK/T cell lymphoma. The significance of raising physician awareness regarding pediatric oral EBV associated CD30 positive lymphoproliferative disease of the oral cavity lies in preventing inadvertent exposure to toxic chemotherapeutic agents intended for treatment of aggressive look-alikes, namely anaplastic large cell lymphoma. Additionally, we include a literature review of similar reports of pediatric intra-oral EBV positive CD30 positive T cell lymphoproliferative disease. PMID- 30292066 TI - Targeting DDX3 in Medulloblastoma Using the Small Molecule Inhibitor RK-33. AB - Medulloblastoma is the most common malignant tumor that arises from the cerebellum of the central nervous system. Clinically, medulloblastomas are treated by surgery, radiation, and chemotherapy, all of which result in toxicity and morbidity. Recent reports have identified that DDX3, a member of the RNA helicase family, is mutated in medulloblastoma. In this study, we demonstrate the role of DDX3 in driving medulloblastoma. With the use of a small molecule inhibitor of DDX3, RK-33, we could inhibit growth and promote cell death in two medulloblastoma cell lines, DAOY and UW228, with IC50 values of 2.5 MUM and 3.5 MUM, respectively. Treatment of DAOY and UW228 cells with RK-33 caused a G1 arrest, resulted in reduced TCF reporter activity, and reduced mRNA expression levels of downstream target genes of the WNT pathway, such as Axin2, CCND1, MYC, and Survivin. In addition, treatment of DAOY and UW228 cells with a combination of RK-33 and radiation exhibited a synergistic effect. Importantly, the combination of RK-33 and 5 Gy radiation caused tumor regression in a mouse xenograft model of medulloblastoma. Using immunohistochemistry, we observed DDX3 expression in both pediatric (55%) and adult (66%) medulloblastoma patients. Based on these results, we conclude that RK-33 is a promising radiosensitizing agent that inhibits DDX3 activity and down-regulates WNT/beta-catenin signaling and could be used as a frontline therapeutic strategy for DDX3-expressing medulloblastomas in combination with radiation. PMID- 30292068 TI - The erector spinae plane (ESP) block: A pooled review of 242 cases. AB - STUDY OBJECTIVE: The erector spinae plane block (ESPB) was first described in 2016 as a regional block for thoracic neuropathic pain. Given its short history, there are a paucity of controlled clinical trials, yet an abundance of case reports. The primary aim of this review is to examine pooled clinical data from published literature to gain an understanding of ESPB characteristics. DESIGN: A PubMed search was conducted to identify all ESPB related publications. Inclusion criteria included reports of ESP single shot, continuous infusion, intermittent bolus, human and cadaveric studies. Only publications obtained in English were included. Measures included type of publication, year and country of publication, journal of publication, block technique, anatomic location, age, opioid and adjunct pain medication use, sensory and motor changes, side effects and adverse events. Qualitative statistics were used. MAIN RESULTS: The initial search yielded 201 publications. After application of inclusion and exclusion criteria, 85 publications from 21 journals were included in the pooled review which yielded 242 reported cases between 2016 and 2018. The majority of publications reported single shot techniques (80.2%), followed by intermittent boluses (12.0%) and continuous infusions (7.9%). 90.9% reported use of multimodal analgesia in addition to the ESPB and 34.7% reported sensory changes from ESPB. A reduction in opioid use was reported in 34.7% of cases. One adverse event involving a pneumothorax was reported. CONCLUSIONS: To our knowledge, this is the first review providing a pooled review of ESPB characteristics. The ESPB appears to be a safe and effective option for multiple types thoracic, abdominal, and extremity surgeries. PMID- 30292069 TI - Incidence of postoperative delirium in elderly ambulatory patients: A prospective evaluation using the FAM-CAM instrument. AB - BACKGROUND: While the incidence of postoperative delirium is high in aged hospitalized patients undergoing major surgery, little is known concerning patients undergoing ambulatory surgery. OBJECTIVE: To determine the incidence of postoperative delirium in aged patients after hospital discharge from an ambulatory surgery unit. DESIGN: Prospective observational study. PATIENTS: Elderly patients (>=75 years) scheduled for a surgical procedure on an ambulatory basis. INTERVENTIONS: Filling of the Family Confusion Assessment Method (FAM-CAM) questionnaire (11 items) during a phone interview of family caregivers on two separate occasions: five to three days before surgery, and three to five days after surgery. MAIN OUTCOME MEASURES: The detection of acute onset and fluctuating course inattention, disorganized thinking, altered level of consciousness, disorientation, perceptual disturbances, and psychomotor agitation from the observations of family caregivers. RESULTS: Signs of delirium appeared de novo in 2 of 141 patients (incidence 1.4%) in the postoperative period: a 80 years old man who was disoriented and had incoherent and illogical speech on postoperative day 1 of resection of a cephalic cutaneous melanoma under local anesthesia and sedation (midazolam, sufentanil, and propofol), and a 83-years old woman with a pre-existing mental confusion, who experienced visual and hearing hallucinations and had inappropriate behaviour on postoperative day 2 of cataract surgery performed under episcleral block. Both patients returned to their preoperative states within a few days. CONCLUSIONS: Using the FAM-CAM instrument for the detection of postoperative delirium in ambulatory patients, the study showed that the incidence of cognitive changes in the ambulatory setting is very low. Among several putative factors, the lightness of the surgical procedure, the wide use of regional anesthesia, and the short hospital stay may be contributing factors to this result. The findings of this study need to be confirmed in a larger sample of patients. PMID- 30292070 TI - Post-traumatic stress and gambling related cognitions: Analyses in inpatient and online samples. AB - Individuals with gambling disorder (GD) report much higher rates of post traumatic stress symptoms and post-traumatic stress disorder (PTSS/D) than the general population, and individuals with both PTSS/D and GD often report much greater distress and impairment in daily life in comparison to individuals with GD alone (Grubbs, Chapman, Milner, Gutierrez, & Bradley, 2018). Despite these associations, little is known about the specific ways in which PTSS/D and GD might influence each other. To address this gap in research, the present work sought to examine how PTSD might be related to the expression and experience of gambling related cognitions. Specifically, it was hypothesized that individuals with PTSD or symptoms of PTSD (i.e., subclinical levels of post-traumatic stress) would demonstrate greater cognitive distortions and erroneous beliefs about gambling. To test these hypotheses, we analyzed data from two samples, an inpatient sample of U.S. Armed Forces veterans seeking treatment for gambling disorder (n = 332) and an online sample of largely recreational gambling U.S. adults (n = 589). Results consistently revealed that, in both samples, individuals with PTSD or symptoms of PTSD were likely to report greater gambling related cognitions. These findings persisted, even when gambling symptom severity and trait neuroticism were held constant. Collectively, these results suggest that PTSD is uniquely associated with greater cognitive distortions and erroneous beliefs about gambling behaviors. These findings bear distinct implications for current understandings of how PTSS/D and GD are related, as well as for treatment of individuals with dealing with this comorbidity. PMID- 30292071 TI - High serum uric acid is associated with oxidation of nucleosides in patients with type 2 diabetes. AB - Uric acid presents different roles in an organism, since it can act as an antioxidant or a pro-oxidant molecule. High serum uric acid levels may cause damage to several structures, including nucleic acids and its components. Therefore, in this study the association between increased serum uric acid concentrations and oxidation of nucleosides was investigated by assessment of urinary 8-hydroxydeoxyguanosine (8-OHdG) in patients with type 2 diabetes (T2D) and in healthy individuals. Urinary 8-OHdG and biochemical parameters were assessed in 61 patients who were initially grouped into 2 groups based on the median serum uric acid levels (<5.3 mg/dL and >=5.3 mg/dL). Urinary 8-OHdG was higher in patients with T2D and serum uric acid levels >=5.3 mg/dL, when compared with the patients with serum uric acid levels <5.3 mg/dL; however, co-occurrence of high serum uric acid with high urinary 8-OHdG was not observed in healthy individuals. A significant positive correlation between 8-OHdG and uric acid (r = 0.40, P < 0.01) was observed in patients with T2D. High serum uric acid levels were associated with high urinary 8-OHdG levels in patients with T2D, and this association was independent of gender, hypertension, body mass index, and serum creatinine. PMID- 30292072 TI - Richer, wiser and in better health? The socioeconomic gradient in hypertension prevalence, unawareness and control in South Africa. AB - The socioeconomic gradient in chronic conditions is clear in the poorest and wealthiest of countries, but extant evidence on this relationship in low- and middle-income countries is inconclusive. We use data gathered between 2008 and 2012 from a nationally representative sample of over 10,000 South African adults, and objective health measures to analyse the differential effects of education, income and other factors on the prevalence of hypertension, individuals' awareness and control of hypertensive status. Prevalence of hypertension is high at 38% among women and 34% among men. 59% of hypertensive individuals are unaware of their status. We find prevalence and unawareness of hypertension are a public health concern across all income groups in South Africa. Higher income is however associated with effective control amongst men. Completing secondary education is associated with 7 mmHg lower blood pressure only in a small sub-group of women but is associated with 22 percentage point higher likelihood of effective hypertension control amongst women. We conclude that poorer and less educated individuals are particularly at high risk of cardiovascular disease in South Africa.

PMID- 30292074 TI - Rapid detection method and portable device based on the photothermal effect of gold nanoparticles. AB - Gold nanoparticle (GNP)-labeled immunochromatography test strip (ICTS) has been widely used in different fields, but its sensitivity still require further improvement. In this work, a rapid and quantitative test strip detection method based on the photothermal effect of GNPs was established using a temperature sensor. A portable sensor device was fabricated based on the above method, and the main operating parameters were optimized. Three types of analyte models (cells, macromolecules, and small molecules) were chosen to evaluate the application of the sensor device using the commercial ICTS. The detection limit is at least 1 order of magnitude lower than that of the traditional visual detection ICTS. The other strip type of dot immunogold filtration test was adopted to further improve the sensitivity. The sensitivity of the sensor detection method was similar to that of the infrared camera method, and the proposed sensor device has obvious advantage of low-cost, as well as the usage of a small portable instrument, ease of use and rapid test. The portable sensor device based on the photothermal effect of GNPs can be used as a new and promising device for simple, quantitative, rapid, and on-site screening of analyte by ICTS. PMID- 30292075 TI - Co3O4 nanostructures on flexible carbon cloth for crystal plane effect of nonenzymatic electrocatalysis for glucose. AB - This work accounts the influence of facet effect of Co3O4 nanocrystals towards nonenzymatic electrocatalysis of glucose induced by different crystal planes modified on carbon cloth (CC) electrode. Tuning the molar ratio of precursor compounds during hydrothermal synthesis of Co3O4, followed by thermal decomposition protocols, different crystal structure including nanocubes, nanothorns, nanooctahedrons and nanosheets were obtained with respective {001}, {110}, {111} and {112} facets. The electrochemical results of these different Co3O4 crystals demonstrate that the nanooctahedron with crystal plane of {111} displays the best nonenzymatic electro-catalytic glucose activity with widest linear range (0.5-1000 MUM), highest sensitivity (246.8 MUA mM-1) and detection limit of 0.012 MUM (S/N = 3). Interestingly, the electrocatalytic activity for nonenzymatic electro-catalytic glucose is ranked in the order of {111} > {112} > {110} > {001}. PMID- 30292078 TI - Control of adhesion and protrusion in cell migration by Rho GTPases. AB - Cell migration is a critical process that underpins a number of physiological and pathological contexts such as the correct functioning of the immune system and the spread of metastatic cancer cells. Central to this process are the Rho family of GTPases, which act as core regulators of cell migration. Rho GTPases are molecular switches that associate with lipid membranes and act to choreograph molecular events that underpin cell migration. Specifically, these GTPases play critical roles in coordinating force generation through driving the formation of cellular protrusions as well as cell-cell and cell-matrix adhesions. Here we provide an update on the many roles of Rho-family GTPases in coordinating protrusion and adhesion formation in the context of cell migration, as well as describing how their activity is controlled to by a variety of complex signalling networks. PMID- 30292076 TI - Altered topology of the functional speech production network in non fluent/agrammatic variant of PPA. AB - Non-fluent/agrammatic primary progressive aphasia (nfvPPA) is caused by neurodegeneration within the left fronto-insular speech and language production network (SPN). Graph theory is a branch of mathematics that studies network architecture (topology) by quantifying features based on its elements (nodes and connections). This approach has been recently applied to neuroimaging data to explore the complex architecture of the brain connectome, though few studies have exploited this technique in PPA. Here, we used graph theory on functional MRI resting state data from a group of 20 nfvPPA patients and 20 matched controls to investigate topological changes in response to focal neurodegeneration. We hypothesized that changes in the network architecture would be specific to the affected SPN in nfvPPA, while preserved in the spared default mode network (DMN). Topological configuration was quantified by hub location and global network metrics. Our findings showed a less efficiently wired and less optimally clustered SPN, while no changes were detected in the DMN. The SPN in the nfvPPA group showed a loss of hubs in the left fronto-parietal-temporal area and new critical nodes in the anterior left inferior-frontal and right frontal regions. Behaviorally, speech production score and rule violation errors correlated with the strength of functional connectivity of the left (lost) and right (new) regions respectively. This study shows that focal neurodegeneration within the SPN in nfvPPA is associated with network-specific topological alterations, with the loss and gain of crucial hubs and decreased global efficiency that were better accounted for through functional rather than structural changes. These findings support the hypothesis of selective network vulnerability in nfvPPA and may offer biomarkers for future behavioral intervention. PMID- 30292077 TI - Longitudinal changes in the mismatch field evoked by an empathic voice reflect changes in the empathy quotient in autism spectrum disorder. AB - Autism spectrum disorders (ASDs) are neurodevelopmental conditions with impairments in social communication and interaction. Empathy is the ability to understand and share another person's inner life, and it is an essential process in social cognition, which is deficient in ASD. The mismatch field (MMF) has been used as a neurophysiological marker for the automatic detection of changes in auditory stimuli. In the present study, we focused on long-term changes in MMF evoked by an empathic voice and changes in the empathy quotient (EQ) in ASD during an 8-week clinical trial using oxytocin (OT). Ten males with ASD without intellectual disability participated in this pilot study. The results demonstrated a significant positive correlation between the change in the MMF amplitude in the auditory cortex (i.e., right banks of the superior sulcus) and the change in the EQ score during the 8-week clinical trial, whereas no significant change was observed in the MMF amplitude or EQ score after the administration period of OT. Although we cannot conclude that the observed relationships were caused by OT's effect or by natural changes, our results suggest that MMF evoked by social voice can be a state-dependent marker of empathic abilities in male adults with ASD. PMID- 30292079 TI - Effect of subthalamic nucleus deep brain stimulation on visual scanning. AB - OBJECTIVE: Deep brain stimulation (DBS) can provide insights into the workings of the basal ganglia (BG) by interfering with their function. In patients with Parkinson's disease (PD) treated with DBS of the subthalamic nucleus, we studied the effect of DBS on scanning eye movements. METHODS: In the visual memory task, subjects viewed images of various complexities for later recall. In visual search tasks, subjects looked for and fixated one odd target ring, embedded among 48 Landolt rings, which either stood out or not from the distractors. We compared the parameters of scanning saccades when DBS was on and off. RESULTS: In the visual memory task, DBS increased the amplitude of saccades scanning simple but not complex drawings. In the visual search tasks, DBS showed no effect on saccade amplitude or frequency. CONCLUSIONS: Saccades when viewing simple images were affected by DBS since they are internally guided saccades, for which the involvement of BG is large. In contrast, saccades when viewing complex images or during visual search, made with the help of visual cues in the images (externally guided saccades) and less dependent on BG, were resistant to the effect of DBS. SIGNIFICANCE: DBS affects saccades differentially depending on the task. PMID- 30292080 TI - Little effort with big effect - implementing the new IFCN 2017 recommendations on standard EEGs. PMID- 30292081 TI - Pulmonary rehabilitation and oropharyngeal exercises as an adjunct therapy in obstructive sleep apnea: a randomized controlled trial. AB - OBJECTIVE: It is well recognized that the most effective treatment for obstructive sleep apnea (OSA) is continuous positive airway pressure (CPAP). Different treatment possibilities comprise surgery, mandibular advancement, pulmonary rehabilitation, and oropharyngeal and facial exercises (PR program). However, these treatments showed inconsistent results. The purpose of the study was to compare the short-term effects of CPAP and the combination of PR program with CPAP on OSA severity, ventilatory functions, and changes in body characteristics in a newly diagnosed patient. METHODS: This study was a single center, two-arm, parallel, randomized, controlled, open-label trial. Forty patients with OSA (20 men, 20 women, aged 54.2 +/- 6.8 years) with moderate to severe obstructive sleep apnea were randomized to CPAP and CPAP + PR. The PR group underwent six weeks of 60-min twice-weekly individual PR programs. The primary outcome measure was apnea/hypopnea index, oxygen desaturation index, and Epworth Sleepiness Scale. The secondary outcome measures were a percentage of total sleep time with oxygen saturation below 90%, body mass index (BMI), vital capacity and forced expiratory volume in 1 s (% of predicted), neck, waist, and hip circumferences. RESULTS: Five patients with OSA did not complete the program. The comparison between baseline and final assessment was made in 15 patients in the CPAP + PR group and 20 patients in the control group with CPAP only. Although OSA severity was controlled with CPAP treatment in both groups, a significant reduction of neck, waist, and hip circumferences, BMI, and improvement of pulmonary function were confirmed only in the CPAP + PR group after treatment. CONCLUSION: Treatment with CPAP combined with the PR program improved OSA patients to a greater extent than only CPAP. PMID- 30292082 TI - Yoga and body image: How do young adults practicing yoga describe its impact on their body image? AB - This study explored the perceived impact of yoga on body image. Young adults (n= 34 female, 12 male; Mage = 30.6 [SD = 1.6]) practicing yoga were interviewed and data were analyzed for emerging themes across weight status. In general, participants discussed the positive impact of yoga on their body image, but some described both a positive and negative impact. Yoga was perceived as having a positive impact on body image via perceived physical changes, gratitude for one's body, a sense of accomplishment within one's yoga practice, self-confidence, and witnessing different types of bodies practicing yoga. Yoga was perceived to have a negative impact on body image via comparative critique (e.g., upward comparisons with others) and inner critique (e.g., negative self-talk). Themes were generally similar across weight status; exceptions were that participants at higher weight status were more likely than those at lower weight status to discuss accomplishment within one's yoga practice as a positive impact on body image and comparative critique as a negative impact on body image. Yoga studios and instructors can take steps to further enhance the positive impact of yoga and to provide environments that are inclusive of participants with diverse body shapes and sizes. PMID- 30292084 TI - The association between suicidal ideation and lifetime suicide attempts is strongest at low levels of depression. AB - Suicidal ideation and depression alone are poor predictors of subsequent engagement in suicidal behavior. Evidence suggests, however, that the lethargy associated with depression may serve as a protective factor against suicide attempts. The purpose of this study was to examine whether suicidal ideation and depression symptoms interact in relation to lifetime suicide attempts among a sample of psychiatric outpatients. A sample of 739 psychiatric outpatients (Mage = 27.26, 60.8% female, 73.3% White/European American) from a university affiliated clinic completed a battery of self-report measures prior to their initial intake appointments. Consistent with hypotheses, a significant interaction emerged between suicidal ideation and depression symptoms in association with lifetime suicide attempts, such that the relationship between suicidal ideation and lifetime suicide attempts was strongest at low, as opposed to high, levels of depression. These findings align with previous research suggesting that lethargy may be a protective factor against suicide attempts, and conversely, that heightened arousal may serve as a suicide risk factor. Our results also point to a configuration of suicidal ideation and depression symptoms that might reflect higher suicide risk. PMID- 30292083 TI - Fragmentation of kidney epithelial cell primary cilia occurs by cisplatin and these cilia fragments are excreted into the urine. AB - The primary cilium, which protrudes from the cell surface, is associated with the pathogenesis of various diseases, including acute kidney injury (AKI). Primary cilium length dynamically changes during the progression of diseases. However, its relevance in disease and the underlying mechanism are largely unknown. In this study, we investigated the role of primary cilia in AKI induced by cisplatin, an effective anticancer drug, and the underlying mechanisms. In addition, we evaluated the usefulness of length alteration and deciliation of primary cilia into the urine for the diagnosis of AKI. Cisplatin induced shortening, elongation, and normalization of the primary cilia in kidney epithelial cells over time. During shortening, primary cilia fragments and ciliary proteins were excreted into the urine. During deciliation, cell proliferation and the expression of cyclin-dependent kinase inhibitor and proliferating cell nuclear antigen were not significantly changed. Shortening and deciliation of primary cilia were observed before significant increases in plasma creatinine and blood urea nitrogen concentration occurred. Pretreatment with Mito Tempo, a mitochondria-targeted antioxidant, prevented cisplatin-induced primary cilium shortening and inhibited the increases in superoxide formation, lipid peroxidation, blood urea nitrogen, and tissue damage. In contrast, isocitrate dehydrogenase 2 (Idh2) gene deletion, which results in defect of the NADPH associated mitochondrial antioxidant system, exacerbated cisplatin-induced changes in mice. Taken together, our findings demonstrate that cisplatin induces deciliation into the urine and antioxidant treatment prevents this deciliation, renal dysfunction, and tissue damage after cisplatin injection. These results suggest that cisplatin-induced AKI is associated with primary cilia and urine primary cilia proteins might be a non-invasive biomarker of kidney injury. PMID- 30292085 TI - Does mindfulness help people adapt to the experience of hearing voices? AB - Mindfulness-based interventions show promise in the treatment of psychotic symptoms. From a theoretical perspective, there may be several benefits of mindfulness for individuals who experience hearing voices. Related cross sectional findings suggest mindfulness may protect against distress, disruption, negative beliefs, dysfunctional relational style and responding, and mood symptoms for individuals who hear voices. To extend on previous findings, this study aimed to identify whether mindful relating to voices predicted voice related negative impacts (distress, disruption and resistance), when the influence of voice-topography and mood symptoms were controlled for. Overall, 62 participants with a psychotic disorder who had experienced hearing voices in the previous week were given the Southampton Mindfulness of Voices Questionnaire, Psychotic Symptom Rating Scales, Beliefs About Voices Questionnaire, Beck Depression Inventory-II, and Beck Anxiety Inventory. As predicted, greater mindfulness of voices predicted less voice-related distress and lower resistance to voices. Regression analyses revealed that when associated voice topography and mood symptoms were controlled for, mindful relating to voices explained a significant proportion of variance in voice-related distress and resistance. Conversely, mindfulness of voices did not significantly predict voice-related disruption. In the context of existing literature, these findings suggest further mindfulness-based protocols for persistent voices should be developed and trialled. PMID- 30292086 TI - Self-efficacy and emotionally dysregulated behaviour: An exploratory test of the role of emotion regulatory and behaviour-specific beliefs. AB - We examined the relationship between self-efficacy and three behaviours that can serve similar affect-regulatory functions (self-injury, risky alcohol use, disordered eating). We proposed that general self-efficacy would be indirectly related to each outcome, operating via emotion regulatory self-efficacy and behaviour-specific self-efficacy. A path analysis confirmed this proposal in a sample of 490 university students, who completed questionnaires assessing the constructs of interest. Emotion regulatory self-efficacy was a salient predictor of self-injury and disordered eating, evidencing both direct and indirect relationships. Self-efficacy to resist each of the behaviours was uniquely related to its target behaviour. We discuss these findings, outlining the implications for a theoretical understanding of emotion-regulatory behaviours, and offer suggestions for prevention and early intervention initiatives. PMID- 30292087 TI - Antipsychotics and cardiovascular risk: A case/non-case study. AB - Severe mental disorders have been reported to be associated with an increased cardiovascular risk. To measure the potential risk excess as compared, not with the baseline cardiovascular risk for the general population, but with the cardiovascular risk associated with drug iatrogenia. 197 reported cases of cardiovascular adverse reaction to antipsychotic drugs as compared to the reported cases of this type of adverse reactions to drugs other than antipsychotics entered in the Spanish Pharmacovigilance System database (FEDRA) (1995-2018) in an observational case/non-case study. Risk estimates of association were reporting odds ratio (ROR), and, chi-square test (chi2). Overall disproportionality for the whole drug class was found [ROR 2.3 (95% CI 2.0-2.7)], chi2 = 127.07]. When the two types of antipsychotics (typical and atypical) were analysed separately, we also found statistically significant disproportionality, and this disproportionality is similar between both groups, with disproportionality measures around 2.30, with the confidence intervals not including the 1. The disproportionality observed suggests a risk excess that might be greater than expected, which holds particularly true for torsade de pointes, sudden death and cardiac arrhythmias in patients treated with any of the two types of antipsychotics. There was no significant risk for ischaemic heart disease. PMID- 30292088 TI - White matter hyperintensities are linked to future cognitive decline in de novo Parkinson's disease patients. AB - White Matter Hyperintensities (WMHs) are associated with cognitive decline in aging and Alzheimer's disease. However, the pathogenesis of cognitive decline in Parkinson's disease (PD) is not as clearly related to vascular causes, and therefore the role of WMHs as a marker of small-vessel disease (SVD) in PD is less clear. Currently, SVD in PD is assessed and treated independently of the disease. However, if WMH as the major MRI sign of SVD has a higher impact on cognitive decline in PD patients than in healthy controls, vascular pathology needs to be assessed and treated with a higher priority in this population. Here we investigate whether the presence of WMHs leads to increased cognitive decline in de novo PD, and if these effects relate to cortical atrophy. WMHs and cortical thickness were measured in de novo PD patients and age-matched controls (NPD = 365, NControl = 174) from Parkinson's Progression Markers Initiative (PPMI) to study the relationship between baseline WMHs, future cognitive decline (follow up: 4.09 +/- 1.14 years) and cortical atrophy (follow-up: 1.05 +/- 0.10 years). PD subjects with high baseline WMH loads had significantly greater cognitive decline than i) PD subjects with low WMH load, and ii) control subjects with high WMH load. Furthermore, in PD subjects, high WMH load resulted in more cortical thinning in the right frontal lobe. Theses results show that the presence of WMHs in de novo PD patients predicts greater future cognitive decline and cortical atrophy than in normal aging. PMID- 30292091 TI - Immunomodulatory effect of natural and modified Citrus pectin on cytokine levels in the spleen of BALB/c mice. AB - Pectin is present in the cell wall of different vegetables and fruits. Beside its importance in the plant cell wall, pectin has enticed great attention for its beneficial effects on human health. It was shown to decrease cholesterol levels, to possess anti-oxidative, anti-bacterial and anti-cancer activity. The immunomodulatory activity of pectin and its mechanism of action is recently being investigated. In this study, the differential immunomodulatory activities of both CP (citrus pectin) and MCP (modified citrus pectin) were investigated. Females BALB/c mice (20-25 g) were randomly divided into 7 groups and different concentrations of CP and MCP (0%, 1.5%, 3% and 5%) were added to their drinking water for 21 days. Then, the splenic level of IL-1beta, IL-4, IL-10, IL-17, IFN gamma and TNF-alpha were evaluated using ELISA. Both CP and MCP exhibited immunomodulatory activities by increasing the levels of the pro-inflammatory cytokines IL-17, IFN-gamma and TNF-alpha levels. This tendency seems to be regulated by the up-regulation of IL-4 levels but with no major effect on those of IL-10. Therefore, CP and especially MCP have potential immunomodulatory effects which might be highly beneficial in immunotherapy. PMID- 30292092 TI - Viscoelastic properties of microgel thin films control fibroblast modes of migration and pro-fibrotic responses. AB - Cell behavior is influenced by the biophysical properties of their microenvironments, and the linear elastic properties of substrates strongly influences adhesion, migration, and differentiation responses. Because most biological tissues exhibit non-linear elastic properties, there is a growing interest in understanding how the viscous component of materials and tissues influences cell fate. Here we describe the use of microgel thin films with controllable non-linear elastic properties for investigating the role of material loss tangent on cell adhesion, migration, and myofibroblastic differentiation, which have implications in fibrotic responses. Fibroblast modes of migration are dictated by film loss tangent; high loss tangent induced ROCK-mediated amoeboid migration while low loss tangent induced Rac-mediated mesenchymal cell migration. Low loss tangent films were also associated with higher levels of myofibroblastic differentiation. These findings have implications in fibrosis and indicate that slight changes in tissue viscoelasticity following injury could contribute to early initiation of fibrotic related responses. PMID- 30292090 TI - CSF pro-orexin and amyloid-beta38 expression in Alzheimer's disease and frontotemporal dementia. AB - There is an unmet need for markers that can stratify different forms and subtypes of dementia. Because of similarities in clinical presentation, it can be difficult to distinguish between Alzheimer's disease (AD) and frontotemporal dementia (FTD). Using a multiplex targeted proteomic LC-MS/MS platform, we aimed to identify cerebrospinal fluid proteins differentially expressed between patients with AD and FTD. Furthermore analysis of 2 confirmed FTD genetic subtypes carrying progranulin (GRN) and chromosome 9 open reading frame 72 (C9orf72) mutations was performed to give an insight into the differing pathologies of these forms of FTD. Patients with AD (n = 13) demonstrated a significant (p < 0.007) 1.24-fold increase in pro-orexin compared to FTD (n = 32). Amyloid beta-38 levels in patients with AD were unaltered but demonstrated a >2-fold reduction (p < 0.0001) in the FTD group compared to controls and a similar 1.83-fold reduction compared to the AD group (p < 0.001). Soluble TREM2 was elevated in both dementia groups but did not show any difference between AD and FTD. A further analysis comparing FTD subgroups revealed slightly lower levels of proteins apolipoprotein E, CD166, osteopontin, transthyretin, and cystatin C in the GRN group (n = 9) compared to the C9orf72 group (n = 7). These proteins imply GRN FTD elicits an altered inflammatory response to C9orf72 FTD. PMID- 30292089 TI - A meta-analytic study of experimental and chronic orofacial pain excluding headache disorders. AB - Chronic orofacial pain (COFP) disorders are prevalent and debilitating pain conditions affecting the head, neck and face areas. Neuroimaging studies have reported functional and grey matter abnormalities, but not all the studies have reported consistent findings. Identifying convergent abnormalities across COFPs provides a basis for future hypothesis-driven research aimed at elucidating common CNS mechanisms. Here, we perform three coordinate-based meta-analyses according to PRISMA guidelines to elucidate the central mechanisms of orofacial pain disorders. Specifically, we investigated consistent patterns of: (1) brain function to experimental orofacial pain in healthy subjects, (2) structural and (3) functional brain abnormalities in COFP. We computed our coordinate-based meta analyses using GingerALE. The experimental pain meta-analysis revealed increased brain activity in bilateral thalami, posterior mid-cingulate cortices, and secondary somatosensory cortices, the right posterior parietal cortex extending to the orofacial region of the right primary somatosensory cortex and the right insula, and decreased activity in the right somatomotor regions. The structural COFP meta-analysis identified consistent higher grey matter volume/concentration in the right ventral thalamus and posterior putamen of COFP patients compared to healthy controls. The functional COFP meta-analysis identified a consistent increase in brain activity in the left medial and posterior thalamus and lesser activity in the left posterior insula in COFP, compared to healthy controls. Overall, these findings provide evidence of brain abnormalities in pain-related regions, namely the thalamus and insula, across different COFP disorders. The convergence of thalamic abnormalities in both structure and function suggest a key role for this region in COFP pathophysiology. PMID- 30292093 TI - Cystic mixed adenoneuroendocrine carcinoma of the pancreas: A case report. AB - INTRODUCTION: Pancreatic mixed adenoneuroendocrine carcinoma (MANEC) is a rare tumor. We report herein a case of pancreatic MANEC with cystic features. PRESENTATION OF CASE: A 67-year-old woman presented with jaundice. A CT scan revealed an 18-mm mass at the pancreatic head that obstructed the common bile duct and another 35-mm cystic lesion containing a mural nodule in the pancreatic body, which was suspected to be an intraductal papillary mucinous carcinoma. A biopsy of the head mass led to the diagnosis of adenocarcinoma. The patient underwent pancreatoduodenectomy, and the body cyst was resected with the head mass. A histopathological analysis revealed that the body cyst had two components, ductal adenocarcinoma and neuroendocrine tumor. We diagnosed the cystic tumor as MANEC. DISCUSSION: Cases of MANEC have been reported as originating from the stomach, small intestine, and colon, but pancreatic MANEC is rare. The histogenesis and the therapeutic strategy for pancreatic MANEC are controversial. CONCLUSION: The clinicopathological features of pancreatic MANEC remain unclear; therefore, more reports of cases of pancreatic MANEC are necessary for a complete analysis. PMID- 30292094 TI - Mediastinal ectopic thyroid mass with normal thyroid function and location: Case report. AB - INTRODUCTION: Mediastinal Ectopic Thyroid Gland is a rare entity, accounting for 1% of all mediastinal tumours. Here, we present a rare case of mediastinal mass that was proved to be an ectopic thyroid with normal thyroid function tests and normal thyroid gland in the cervical location. CASE PRESENTATION: A 32-year-old lady had a road traffic accident, with the incidental discovery of a mediastinal mass on chest radiography. Thyroid function tests were normal. CT scans of the neck and chest revealed a large mediastinal mass compressing the trachea from the left side and extending to the superior part of the anterior mediastinum with normal thyroid gland in the cervical position. Midline Partial Sternotomy was done with complete surgical excision of the mass. It was well circumscribed, multinodular, had firm inconsistency, and grossly looked like a thyroid tissue. Histopathology revealed ectopic thyroid tissue negative for malignancy. Postoperative thyroid ultrasound showed normal thyroid lobes in the neck. DISCUSSION: Ectopic thyroid tissue (ETT) occurs due to failure of the thyroid gland to migrate from foramen ceacum to its normal position in the cervical region in front of the trachea. The most common site of ETT is lingual thyroid and accounts for about 90% of all cases reported in the literature. ETT in the mediastinum is very rare, with only a few cases reported in the literature. CONCLUSION: ETT in the mediastinum is very rare and can be associated with normal thyroid function and normal thyroid anatomical location. It should be differentiated from substernal goiter. PMID- 30292095 TI - Transnationalism, parenting, and child disciplinary practices of African immigrants in Alberta, Canada. AB - Child discipline remains a topic of public health interest across the globe. Despite this enduring interest, very little is known about the child disciplinary practices of African immigrants in Canada. This paper explores the disciplinary practices of African immigrant parents in Alberta, a Canadian province with a recent surge in the population of African immigrants. Employing a critical ethnographic methodology, informed by transnational theory, we collected data through in-depth qualitative interviews with a purposive sample of African community leaders (n = 14), African immigrant parents (n = 32), policymakers (n = 2), and health and immigrant settlement workers (n = 10). As members of the African immigrant community, we were deeply immersed in the research settings, which afforded us the opportunity to collect pertinent observational data in the form of reflexive notes. Thematic analysis of the data revealed child disciplinary approaches that incorporate Canadian and African parenting practices, as well as practices that appear somewhat unique to this demographic. We found that African immigrant parents used corporal discipline, persuasive discipline, and a hybrid of the two, as well as emerging practices involving transnational fostering and emotional isolation of children who persistently misbehaved. These practices, in their totality, appeared to be influenced by the transnational experiences of parents and precepts that are traceable to Canada's legal and educational systems. We present theoretical, policy, and service implications of our findings, including a recommendation to incorporate sociocultural dimensions of child discipline into Canadian child welfare policies and practices. PMID- 30292096 TI - Maternal clinical predictors of preterm birth in twin pregnancies: A systematic review involving 2,930,958 twin pregnancies. AB - In twin pregnancies, which are at high risk of preterm birth, it is not known if maternal clinical characteristics pose additional risks. We undertook a systematic review to assess the risk of both spontaneous and iatrogenic early (<34 weeks) or late preterm birth (<37 weeks) in twin pregnancies based on maternal clinical predictors. We searched the electronic databases from January 1990 to November 2017 without language restrictions. We included studies on women with monochorionic or dichorionic twin pregnancies that evaluated clinical predictors and preterm births. We reported our findings as odds ratio (OR) with 95% confidence intervals (CI) and pooled the estimates using random-effects meta analysis for various predictor thresholds. From 12, 473 citations, we included 59 studies (2,930,958 pregnancies). The risks of early preterm birth in twin pregnancies were significantly increased in women with a previous history of preterm birth (OR 2.67, 95% CI 2.16-3.29, I2 = 0%), teenagers (OR 1.81, 95% CI 1.68-1.95, I2 = 0%), BMI > 35 (OR 1.63, 95% CI 1.30-2.05, I2 = 52%), nulliparous (OR 1.51, 95% CI 1.38-1.65, I2 = 73%), non-white vs. white (OR 1.31, 95% CI 1.20 1.43, I2 = 0%), black vs. non-black (OR 1.38, 95% CI 1.07-1.77, I2 = 98%), diabetes (OR 1.73, 95% CI 1.29-2.33, I2 = 0%) and smokers (OR 1.30, 95% CI 1.23 1.37, I2 = 0%). The odds of late preterm birth were also increased in women with history of preterm birth (OR 3.08, 95% CI 2.10-4.51, I2 = 73%), teenagers (OR 1.36, 95% CI 1.18-1.57, I2 = 57%), BMI > 35 (OR 1.18, 95% CI 1.02-1.35, I2 = 46%), nulliparous (OR 1.41, 95% CI 1.23-1.62, I2 = 68%), diabetes (OR 1.44, 95% CI 1.05-1.98, I2 = 55%) and hypertension (OR 1.49, CI 1.20-1.86, I2 = 52%). The additional risks posed by maternal clinical characteristics for early and late preterm birth should be taken into account while counseling and managing women with twin pregnancies. PMID- 30292097 TI - Fluorescence-based kinetic analysis of miniaturized protein microarrays. AB - Ideal monitoring devices should enjoy a combination of characteristics, e.g. high sensitivity, multiplexing, portability, short time-to-result (TTR). Typically, no device meets all of these demands since some of them are contradictory, to some extent. Herein, we present a miniaturized platform based on fluorescent detection, which is sensitive, readily allows multiplexing, and allows real-time monitoring of the signal, thus allowing extraction of kinetic information as well as drastic reduction of TTR. This is achieved via miniaturization of active spots, integration with microfluidics, and algorithmic approaches. We validate its performance by comparing with evanescent field excitation, which obtains similar results, however without the addition of the necessary complex hardware. PMID- 30292098 TI - Ectopic expression of a Musa acuminata root hair defective 3 (MaRHD3) in Arabidopsis enhances drought tolerance. AB - Genetic improvement is an important approach for crop improvement towards yield stability in stress-prone areas. Functional analysis of candidate stress response genes can provide key information to allow the selection and modification of improved crop varieties. In this study, the constitutive expression of a banana cDNA, MaRHD3 in Arabidopsis improved the ability of transgenic lines to adapt to drought conditions. Transgenic Arabidopsis plants expressing MaRHD3 had roots with enhanced branching and more root hairs when challenged with drought stress. The MaRHD3 plants had higher biomass accumulation, higher relative water content, higher chlorophyll content and an increase in activity of reactive oxygen species (ROS) scavenging enzymes; SOD, CAT, GR, POD and APX with reduced water loss rates compared to control plants. The analysis of oxidative damage indicated lower cell membrane damage in transgenic lines compared to control plants. These findings, together with data from higher expression of ABF-3 and higher ABA content of drought-stressed transgenic MaRHD3 expressing plants, support the involvement of the ABA signal pathway and ROS scavenging enzyme systems in MaRHD3 mediated drought tolerance. PMID- 30292099 TI - Trimethylamine in postmortem tissues as a predictor of postmortem interval estimation using the GC method. AB - Trimethylamine (TMA), a simple amine in volatile compounds, indicating the spoilage degree of meat, related with the late postmortem interval (PMI) during the cadaver decomposition process. In this paper, a headspace gas chromatography (HS-GC) method has been successfully built to analyze the content of TMA in postmortem rat tissues (liver, myocardial and skeletal muscle tissues), which is used for PMI estimation with the wide range of PMI (0-720 h postmortem) at 16 degrees C +/- 1 degrees C. Correspondingly, three equations about the relationship between the PMI and TMA content were established, in which they showed that the TMA content in all three tissues increased from the firstly detected time to 192 h and gradually decreased after 384 h. Furthermore, the TMA measurement in five human samples was carried out and the results (<35 h PMI) showed a good agreement about the change trend of TMA content between human and rat, which elucidated that this research might provide a new insight for the forensic scientist to band HS-GC technology together with TMA determination in the PMI estimation. PMID- 30292100 TI - Dynamic evaluation of simulated leg length inequalities and their effects on the musculoskeletal apparatus. AB - BACKGROUND: Leg length inequalities (LLI) are a common problem in medicine. So far, the diagnosis and treatment are performed under static conditions. Surface Topography (ST) is an optical, non-invasive technique that uses the principle of triangulation to measure spinal posture and pelvic position. This technique offers the opportunity to detect and treat LLIs and their effects under dynamic conditions. RESEARCH: question The aim of the study is to show that ST can detect simulated LLIs under dynamic conditions and to prove if there are differences between the effects on the human body under static and dynamic conditions. METHODS: In the clinical study a total of 30 test subjects were examined with a ST measuring device. LLIs (1 to 4 cm) were simulated using a custom- built sandal and insoles of various thickness. The pelvic obliquity, the surface rotation and lateral deviation of the spine were detected on a treadmill under static and dynamic conditions (3 km/h). RESULTS: Under static and dynamic conditions LLIs lead to a significant increase of all measured parameters. The pelvic obliquity reaches a significant level of p < 0.0001 under static and p = 0.0001-0.0421 under dynamic conditions. However, for all examined parameters the magnitudes of the parameters under dynamic conditions were smaller than under static conditions. SIGNIFICANCE: The study showed that simulated LLIs also have a significant effect on the human pelvis and spine under dynamic conditions, but with a smaller magnitude than under static conditions. The human individuum is a dynamic one. Because of that, for the future it should be of great interest to use dynamic measurements to detect and treat LLIs to provide an over correction of LLIs. PMID- 30292101 TI - Hypnotic and non-hypnotic suggestion to ignore pre-cues decreases space-valence congruency effects in highly hypnotizable individuals. AB - Previous studies have shown that the speed of identifying emotional words is affected by pre-cues of up or down arrows, called the space-valence congruency effect (Zhang, Hu, Zhang, & Wang, 2015). In the present study, we investigate whether this effect is influenced by hypnotic or non-hypnotic suggestions to ignore pre-cues in highly hypnotizable individuals (HHIs). In all conditions, target words (including positive words, negative words and neutral words) primed by up or down arrows were presented to pre-screened HHIs. They were asked to identify whether the target words had emotional valence. Behavioral results showed that the space-valence congruency effect was absent in the hypnotic and non-hypnotic suggestion groups, but present in the non-suggestion control group. Consistently, the amplitudes of P2 components elicited by negative words were significantly larger when primed by down than by up arrows in the non-suggestion control group, and this P2 effect was absent in the hypnotic and non-hypnotic suggestion groups. Moreover, the amplitudes of the late positive components (LPC) showed no significant arrow-priming difference for positive targets in the hypnotic-suggestion and control groups. However, in the non-hypnotic suggestion group, the amplitudes of LPC were significantly larger when primed by down than up arrows for positive targets. Our results showed that suggestions, even without a hypnotic induction, can de-automatize embodied emotional recognition processes and modulate early attentional processing.

AB - Triclosan, an antimicrobial micro-pollutant with a high bio-accumulation potential represented by its high octanol-water partition coefficient (log Kow) of 4.76 is commonly encountered in water and wastewater worldwide. The present study focuses on biomimetic surface modification of commercial activated carbon (PAC) with long chain fatty acid namely docosahexaenoic acid (DHA) resulting in enhanced affinity for the hydrophobic micro-pollutant; triclosan (TCS). The sorption process of the resulting modified lipophilic carbon (PACM) was investigated for the effect of various experimental conditions. The Freundlich isotherm and pseudo-second-order kinetic models had a better fit. PACM exhibited the maximum adsorption capacity of 395.2 mg g-1 in contrast to 71.5 mg g-1 obtained for PAC. The surface morphology in terms of surface area, surface acidity, pore size, contact angle, etc. and were also evaluated. The contact angle of 134.3 degrees obtained for PACM confirmed its highly hydrophobic nature. The efficacy of PACM was also evaluated using real-world secondary treated effluent containing triclosan confirming its applicability for tertiary treatment of wastewater. The study established that the biomimetic approach of creating lipid-like sites on the carbon surface results in the enhanced removal of lipophilic micro-pollutants. It can also be utilized for the removal and recovery of a wide variety of other organic micro-pollutants.

AB - The development of novel porous materials for CO2 capture and storage has received increasing attention due to the global warming problem. The aim of this work was to develop novel composites by merging Cu-BTC framework and porous carbon materials, including ordered mesoporous non-activated carbon (OMC), ordered mesoporous activated carbon (AC), and nitrogen-containing microporous carbon (NC) as efficient adsorbents for CO2 capture. The morphology, porosity and surface area of the parent materials and composites were fully characterized. All resulting composites were identified as microporous materials with type I adsorption isotherm. During synthesis of these composites, additional micropores were formed in the interfacial region between heterogeneous phases, which greatly enhances both their specific surface area and porosity. As compared to the parent materials, namely carbons and Cu-BTC, the CO2 uptake capability of the composites is greatly enhanced due to the presence of micropores at the interface. Specifically, NC-Cu-BTC composite exhibited the highest CO2 capacity with ~8.24 and ~4.51 mmol/g under 1 bar at 0 and 25 degrees C, respectively. These novel porous carbon/MOF composites may have great potential for adsorption application including CO2 capture.

AB - Paclitaxel (PTX) is a gold standard chemotherapeutic agent for breast, ovarian, pancreatic and non-small cell lung carcinoma. However, in clinical use PTX can have adverse side effects or inadequate pharmacodynamic parameters, limiting its use. Nanotechnology is often employed to reduce the therapeutic dosage required for effective therapy, while also minimizing the systemic side effects of chemotherapy drugs. However, there is no nanoformulation of paclitaxel with chemosensitization motifs built in. With this objective, we screened eleven pharmaceutical excipients to develop an alternative paclitaxel nanoformulation using a self-assembly method. Based on the screening results, we observed tannic acid possesses unique properties to produce a paclitaxel nanoparticle formulation, i.e., tannic acid-paclitaxel nanoparticles. This stable TAP nanoformulation, referred to as TAP nanoparticles (TAP NPs), showed a spherical shape of ~ 102 nm and negative zeta potential of ~ -8.85. The presence of PTX in TAP NPs was confirmed by Fourier Transform Infrared (FTIR) spectra, thermogravimetric analyzer (TGA), and X-ray diffraction (XRD). Encapsulation efficiency of PTX in TAP NPs was determined to be >=96%. Intracellular drug uptake of plain drug PTX on breast cancer cells (MDA-MB-231) shows more or less constant drug levels in 2 to 6 h, suggesting drug efflux by the P-gp transporters, over TAP NPs, in which PTX uptake was more than 95.52 +/- 11.01% in 6 h, as analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Various biological assays such as proliferation, clonogenic formation, invasion, and migration confirm superior anticancer effects of TAP NPs over plain PTX at all tested concentrations. P-gp expression, beta-tubulin stabilization, Western blot, and microarray analysis further confirm the improved therapeutic potential of TAP NPs. These results suggest that the TAP nanoformulation provides an important reference for developing a therapeutic nanoformulation affording pronounced, enhanced effects in breast cancer therapy. PMID- 30292105 TI - Assembly of pi-functionalized quaternary ammonium compounds with graphene hydrogel for efficient water disinfection. AB - Graphene hydrogels hold great potential for the disinfection of bacteria contaminated water. However, the intrinsic antibacterial activity of graphene hydrogels is not satisfactory, and the incorporation of other antibacterial agents often results in their unwanted releases. Here, we present a new strategy to improve the antibacterial activities of graphene hydrogels. We first synthesized a new pi-conjugated molecule containing five aromatic rings and two side-linked quaternary ammonium (QA) groups, denoted as piQA. Next, we fabricated composite gravity filters by assembling piQA with reduced graphene oxide (rGO) hydrogel. The rGO hydrogel helps to form a sponge-like physical sieve, contributes to the overall antibacterial activity, and provides abundant pi-rich surfaces. The large aromatic cores of piQA allow the formation of collectively strong pi-pi interactions with rGO, resulting in a high piQA mass loading of ~31 wt%. Due to the sieving effect of rGO hydrogel and the synergistic antibacterial activity of rGO and piQA, the filters prepared based on piQA-rGO assemblies can remove over 99.5% of Gram-negative Escherichia coli (E. coli) and Gram-positive Staphylococcus aureus (S. aureus) cells with a high-water treatment capacity of 10 L g-1. Furthermore, the piQA-rGO assemblies show low toxicity towards two different mammalian cell lines (L929 and macrophages), and the release of piQA is also negligible. Overall, the new piQA-rGO assembly demonstrates high potential for water disinfection applications. PMID- 30292106 TI - Understanding the adsorption of sulfonamide antibiotics on MIL-53s: Metal dependence of breathing effect and adsorptive performance in aqueous solution. AB - This investigation is based on experimental data to deeply understand the unusual adsorption behavior of the flexible MIL-53s in aqueous solution. In contrast to the strongly flexible MIL-53(Cr) and MIL-53(Al) with large pore form (lp) in water and in their anhydrous state, MIL-53(Fe) exhibits narrow pore form (np) or very narrow pore form (vnp), indicating that breathing effect depends on the nature of the metal. Sulfamethoxazole (SMZ) adsorption results demonstrated that the maximum adsorption capacities predicted by Langmuir model were 1.85, 1.78 and 0.314 mmol/g for MIL-53(Cr), MIL-53(Al), and MIL-53(Fe), respectively. The adsorption equilibrium was rapidly reached within 60 min and the kinetic data best fitted with the pseudo second order model. The lp form of MIL-53(Cr) and MIL 53(Al) in aqueous solution provided the easy entrance for contaminants, lead to lower binding energy and caused modifications of the hydrophobic/hydrophilic character, which all enhanced their adsorption capacities for SMZ. However, the np form of MIL-53(Fe) with small inner pores and hydrophilicity compromised its adsorption capacity for SMZ. The experimental results revealed electrostatic interactions, hydrogen bonding, and pi-pi interaction/stacking contributed to the adsorption of SMZ on MIL-53s as well. In summary, the complexation of different metal nodes to MOFs is accompanied by the diversity of properties, which significantly affect their adsorptive performance. PMID- 30292107 TI - Liraglutide modulates gut microbiota and reduces NAFLD in obese mice. AB - Metabolic disorders such as insulin resistance and diabetes are associated with obesity and nonalcoholic fatty liver disease (NAFLD). The aggressive form of a fatty liver disease may progress to cirrhosis and hepatocellular carcinoma. Furthermore, recent studies demonstrated that there is a dysbiosis in the gut microbiota associated with early stages of metabolic disease. Therefore, the identification and repurposing of drugs already used to treat insulin resistance may be an excellent option for other disorders. We evaluated the effect of liraglutide on obesity, NAFLD and gut microbiota modulation in two different animal models of obesity: the ob/ob mice and the high-fat diet (HFD)-fed mice. Liraglutide treatment induced significant weight loss in both obesity models, showed improvements in glycemic parameters and reduced inflammatory cell infiltration in the cecum and the liver. In ob/ob mice, the liraglutide treatment was able to reduce the accumulation of liver fat by 78% and reversed steatosis in the HFD mice. The gut microbiota analysis showed that liraglutide changed the overall composition as well as the relative abundance of weight-relevant phylotypes such as a reduction of Proteobacteria and an increase of Akkermansia muciniphila in the treated HFD group. We show that liraglutide can lead to weight loss and gut microbiota modulations, and is associated with an improvement of NAFLD. Furthermore, by generating a profile of the intestinal microbiota, we compiled a list of potential bacterial targets that may modulate metabolism and induce a metabolic profile that is considered normal or clinically controlled. PMID- 30292108 TI - Effect of Fe3O4 NPs application on fluoride (F) accumulation efficiency of Prosopis juliflora. AB - Fluoride (F) pollution is a major worldwide problem affecting approximately 200 million people. Hyperaccumulator plant Prosopis juliflora has been used for the removal of F from contaminated soils; however it's low F accumulation efficiency and low biomass limits the phytoremediation efficiency. Present study deals with enhancement of F uptake efficiency of plant P. juliflora through iron oxide nanoparticles (Fe3O4 NPs) application for remediation of agricultural soils. For the study, Fe3O4 NPs were synthesized through green route using waste jojoba leaves. The application of Fe3O4 NPs significantly increased the shoot and root length of plant P. juliflora. Fe3O4 NPs treatment also promoted the F accumulation in shoot and root tissues upto 28.43 and 34.64 mg kg-1, respectively. Microscopic (FESEM and light microscopic) and EDX spectrum analysis of plant tissues confirmed the accumulation and translocation of Fe3O4 NPs and F in plant tissues This nano-phytoremediation approach could be a better option for F remediation for agricultural and commercial purpose. PMID- 30292109 TI - Antioxidant systems responses and the compatible solutes as contributing factors to lead accumulation and tolerance in Lathyrus sativus inoculated by plant growth promoting rhizobacteria. AB - Short-term lead (Pb) uptake by plants is important to better understand the mechanisms of metal uptake, plant tolerance and detoxification strategy. Thus we examined the response of Lathyrus sativus to 1 mM Pb application in hydroponic sorption kinetics at 24, 48 and 72 h, and we investigated the contribution of two inocula I1 (R. leguminosarum (M5) + B. simplex + Luteibacter sp + Variovorax sp) and I5 (R. leguminosarum (M5) + P. fluorescens (K23) + Luteibacter sp + Variovorax sp) in plant mechanisms responses. Pb application induced its immediate uptake by L. sativus with highest concentrations, which increased gradually mostly for inoculated plants. The control plant shoots accumulated the highest concentration of lead at 24 h. However, at 48 and 72 h this potential uptake was significantly enhanced in plants inoculated with I5. Moreover, inoculation increased significantly root Pb-uptake with the maximum reached at 72 h. We observed a progressive decline in chlorophyll contents after Pb exposure in control plants that was higher than in PGPR-treated plants and the greatest improvement (152%) was recorded in I5 inoculated leaves. The PGPR also promoted significant elevation in the carotenoid content with the highest increases (188%) in plants inoculated with I5 at 72 h. Data illustrated remarkable augmentation in malondialdehyde, ion leakage level and decrease in membrane stability. Whereas, inoculation enhanced significantly cellular membrane integrity through increases in membrane stability index as compared to the control plants. In response to Pb, proline biosynthesis, as well as total soluble sugars concentration, immediately increased and the stimulatory effect was more pronounced in inoculated plants at 72 h. Lead considerably altered the activities of SOD, GPOX, CAT and APX enzymes in leaves and roots in a time- and inoculation- dependent manner. It is concluded that antioxidant enzymes, carotenoids, soluble sugars and proline were involved in the main defense mechanism and tolerance of Lathyrus sativus to Pb oxidative stress, as well lead accumulation, and are likely to operate in combination. PMID- 30292110 TI - Effect of Fe(II) on reactivity of heterotrophic denitrifiers in the remediation of nitrate- and Fe(II)-contaminated groundwater. AB - Heterotrophic denitrifiers, capable of simultaneous nitrate reduction and Fe(II) oxidation, can be applied for the remediation of nitrate and Fe(II) combined contamination in groundwater. Under strictly anaerobic condition, denitrifying microbial communities were enriched with the coexistence of soluble nitrate, Fe(II) and associated nutrient elements to monitor the denitrification process. Low abundance of Fe(II) (e.g., 10 mg L-1 in this study) tended to stimulate the activity of denitrifying microbial communities. However, elevated Fe(II) concentration (50 and 100 mg L-1 in this study), acted as a stress, strongly inhibited the activity and reproduction of denitrifiers. Besides, through thermodynamics calculations, methanol rather than Fe(II) was proved to be the preferable electron donors for both energy metabolism and anabolism. Betaproteobacteria was found to be the most predominant (sub)phylum in all enriched microbial assemblages. Methylovesartilis was the most predominant group mainly catalyzed for methanol based denitrification, and others denitrifiers included Methylophilaceae, Dechloromonas and Denitratisoma. Excessive Fe(II) in the solution greatly reduced the proportions of these denitrifying groups, while the influence seemed to be less apparent on functional genes composition. As such, a conceptional metabolism pathway of the most dominant genus (i.e., Methylovesartilis) for nitrate reducing as well as methanol and Fe(II) oxidation confirmed that biotic nitrate reducing and Fe(II) oxidizing were potentially proceeded in cytoplasm by enzymes such as NarGHI. The Fe(II) oxidation rate depended on the rate of Fe(II) entering into the cell. These findings provide a clear mechanistic understanding of heterotrophic denitrification coupling with Fe(II) oxidation, and environmental implication for the bioremediation of nitrate and Fe(II) contaminated groundwater. PMID- 30292111 TI - Characterization of the dissociation kinetics of Cd and Ni in soils based on diffusive gradients in thin films technique. AB - A new theoretical method was established for the combinatorial calculation of the dissociation rate constant (K-1) of the metal-organic complexes (MLs), the concentration of free ionic soil metals (CM), the labile concentration of soil metal-organic complexes (CML) based on diffusive gradients in thin-films (DGT) technique with a range of diffusive layer thicknesses (0.053-0.173 mm) in soils. The fitting results agreed well with the determined values. The values of K-1, CML and CM were calculated without other morphological analysis software and the fitting results agreed well with the determined values with some advantages such as the use of fewer hypothetical parameters, ease of calculation, the full embodiment of the contribution of MLs to the labile content. According to the results of model fitting, cation exchange capacity and soil organic matter were found to be the key environmental factors for K-1 values of Cd and Ni, respectively. The labile contents of Cd and Ni in soil were closely related with pH, soil organic matter and the total contents of heavy metals. PMID- 30292112 TI - Complexation of U(VI) with Cucurbit[5]uril: Thermodynamic and Structural investigation in aqueous medium. AB - The assessment of cucurbituril (CBn) for selective removal of actinides from nuclear waste streams requires comprehensive understanding of binding parameters and coordination of these complexes. The present work is the first experimental report on complexation of actinide ion with Cucurbit[5]uril (CB5) in solution. The thermodynamic parameters (DeltaG, DeltaH and DeltaS) for complexation of CB5 with U(VI) in formic acid water medium were determined using microcalorimetry and UV-Vis spectroscopy. The enthalpy and entropy of complexation revealed the partial binding of U(VI) to CB5 portal. The partial binding was confirmed by spectroscopic techniques viz. extended X absorption fine structure spectroscopy (EXAFS), 1H and 13C NMR. The EXAFS chi(r) versus r spectra for U-CB5 complex has been fitted from 1.4 to 3.5 A with two oxygen shells and a carbon shell. The presence of three carbon atom in secondary shell shows the involvement of only three carbonyl oxygens directly bonding to U(VI) which is in contrast to that calculated from gas phase DFT calculation of unhydrated system. The combined effect of hydration and formic acid encapsulation led to the enhanced stability of partially bound U(VI) to CB5. In the present work the binding of formic acid has also been studied by fluorescence spectroscopy. ESI-MS data shows the unusual stabilization of U(VI) by CB5 in gas phase. PMID- 30292113 TI - Defunct gold mine tailings are natural reservoir for unique bacterial communities revealed by high-throughput sequencing analysis. AB - Mine tailing dumps are arguably one of the leading sources of environmental degradation with often both public health and ecologically consequences. The present study investigated the concentration of heavy metals in gold mine tailings, and used high throughput sequencing techniques to determine the microbial community diversity of these tailings using 16S rRNA gene based amplicon sequence analysis. The concentration of detected metals and metalloids followed the order Si > Al > Fe > K > Ca > Mg. The 16S rRNA gene based sequence analysis resulted in a total of 273,398 reads across the five samples, represented among 7 major phyla, 41 classes, 77 orders, 142 families and 247 major genera. Phylum Actinobacteria was the most dominant, followed by Proteobacteria, Firmicutes, Chloroflexi, Cyanobacteria, Bacteroidetes, Acidobacteria and Planctomycetes. Redundancy analysis (RDA) and pairwise correlation analysis positively correlated the distribution of Alphaproteobacteria and Gammaproteobacteria to Al and K; Actinobacteria to Cr and Chloroflexi to Si. Negative correlations were observed in the distribution of Bacteroidetes with respect to As concentrations, Actinobacteria to Al, and Alphaproteobacteria and Gammaproteobacteria to high As and Te content of the soils. Predictive functional analysis showed the presence of putative biosynthetic and degradative pathways across the five sample sites. The study concludes that mine tailing sites harbour diverse and unique microbial assemblages with potentially biotechnologically important genes for biosynthesis and biodegradation. PMID- 30292114 TI - Environmental assessment of solar photo-Fenton processes in combination with nanofiltration for the removal of micro-contaminants from real wastewaters. AB - Scarcity of water and concerns about the ecotoxicity of micro-contaminants are driving an interest in the use of advanced tertiary processes in wastewater treatment plants. However, the life cycle environmental implications of these treatments remain uncertain. To address this knowledge gap, this study evaluates through life cycle assessment the following four advanced process options for removal of micro-contaminants from real effluents: i) solar photo-Fenton (SPF) operating at acidic pH; ii) acidic SPF coupled with nanofiltration (NF); iii) SPF operating at neutral pH; and iv) neutral SPF coupled with NF. The results show that acidic SPF coupled with NF is the best option for all 15 impacts considered. For example, its climate change potential is almost three times lower than that of the neutral SPF process (311 vs 928 kg CO2 eq./1000 m3 of treated effluent). The latter is the worst option for 12 impact categories. For the remaining three impacts (acidification, depletion of metals and particulate matter formation), acidic SPF without NF is least sustainable; it is also the second worst option for seven other impacts. Neutral SPF with NF is the second worst technology for climate change, ozone and fossil fuel depletion as well as marine eutrophication. In summary, both types of SPF perform better environmentally with than without NF and the acidic SPF treatment is more sustainable than the neutral version. Thus, the results of this work suggest that ongoing efforts on developing neutral SPF should instead be focused on further improvements of its acidic equivalent coupled with NF. These results can also be used to inform future development of policy related to the removal of micro-contaminants from wastewater. PMID- 30292115 TI - In situ arsenic speciation and the release kinetics in coastal sediments: A case study in Daya Bay, South China Sea. AB - In-situ study on arsenic speciation and the release kinetics in marine sediments was scarce. In this study, the distributions of labile As and their speciation in coastal sediments of Daya Bay were obtained by separate diffusive gradients in thin films (DGT) probes. Results showed that the DGT-labile As(V) was the main speciation in surface sediments (from -20 to 0 mm) with a concentration range of 0.07-3.05 MUg.L-1, while the labile As(III) was the main speciation in deep layers of sediments (from -100 to -20 mm). In coastal areas, mariculture farms was the most dominated contributor to As(V) contamination in surface sediments. Both the apparent diffusion flux estimation and the DGT induced flux in sediments (DIFS) simulation indicated that As(V) contamination in surface sediments of mariculture, harbor and petrochemical areas suffered the potential risk of As(V) release into the overlying water from sediments. DIFS modeling also found that the sediments of mariculture farms were the main sediment As pools. Linear regression analysis indicated that the mobility of As mainly attributed to the As(V) in sediments. PMID- 30292116 TI - Activated carbons of varying pore structure eliminate the bioavailability of 2,3,7,8-tetrachlorodibenzo-p-dioxin to a mammalian (mouse) model. AB - The use of activated carbon (AC) as an in situ sorbent amendment to sequester polychlorinated-dibenzo-p-dioxins and furans (PCDD/Fs) present in contaminated soils and sediments has recently gained attention as a novel remedial approach. This remedy could be implemented at much lower cost while minimizing habitat destruction as compared to traditional remediation technologies that rely on dredging/excavation and landfilling. Several prior studies have demonstrated the ability of AC amendments to reduce pore water concentrations and hence bioaccumulation of PCDD/Fs in invertebrate species. However, our recent study was the first to show that AC had the ability to sequester 2,3,7,8-tetrachlorodibenzo p-dioxin (TCDD) in a form that eliminated bioavailability to a mammalian (mouse) model. Here we show that three commercially available ACs, representing a wide range of pore size distributions, were equally effective in eliminating the bioavailability of TCDD based upon two sensitive bioassays, hepatic induction of cyp1A1 mRNA and immunoglobulin M antibody-forming cell response. These results provide direct evidence that a wide range of structurally diverse commercially available ACs may be suitable for use as in situ sorbent amendments to provide a cost-effective remedy for PCDD/F contaminated soils and sediments. Potentially, adaption of this technology would minimize habitat destruction and be protective of ecosystem and human health. PMID- 30292117 TI - Vent pipe emissions from storage tanks at gas stations: Implications for setback distances. AB - At gas stations, fuel vapors are released into the atmosphere from storage tanks through vent pipes. Little is known about when releases occur, their magnitude, and their potential health consequences. Our goals were to quantify vent pipe releases and examine exceedance of short-term exposure limits to benzene around gas stations. At two US gas stations, we measured volumetric vent pipe flow rates and pressure in the storage tank headspace at high temporal resolution for approximately three weeks. Based on the measured vent emission and meteorological data, we performed air dispersion modeling to obtain hourly atmospheric benzene levels. For the two gas stations, average vent emission factors were 0.17 and 0.21 kg of gasoline per 1000 L dispensed. Modeling suggests that at one gas station, a 1-hour Reference Exposure Level (REL) for benzene for the general population (8 ppb) was exceeded only closer than 50 m from the station's center. At the other gas station, the REL was exceeded on two different days and up to 160 m from the center, likely due to non-compliant bulk fuel deliveries. A minimum risk level for intermediate duration (>14-364 days) benzene exposure (6 ppb) was exceeded at the elevation of the vent pipe opening up to 7 and 8 m from the two gas stations. Recorded vent emission factors were >10 times higher than estimates used to derive setback distances for gas stations. Setback distances should be revisited to address temporal variability and pollution controls in vent emissions. PMID- 30292118 TI - Contrasting impacts of long-term application of manure and crop straw on residual nitrate-N along the soil profile in the North China Plain. AB - The effects of long-term animal manure application and crop straw incorporation on the migration of carbon (C) and nitrogen (N) deep into the soil profile and the associated N leaching risk in particular have not been thoroughly elucidated to date. Soil profile samples were collected from depths of up to 200 cm from the following four treatments in a 27-year field experiment on the North China Plain: N + phosphorus (P) + potassium (K) fertilizers (NPK), NPK + 22.5 t ha-1 swine manure (NPKM), NPK + 33.7 t ha-1 swine manure (NPKM+) and NPK + straw incorporation (NPKS). The results revealed that long-term manure application and straw incorporation significantly enhanced the soil organic C (SOC) and total N (TN) contents in the upper 20 cm and that this effect was weaker in the deeper soil layers (P < 0.05). Residual nitrate-N (NO3--N) contents at 0 to 40 cm and 120 to 200 cm in the NPKM and NPKM+ were 4-16 and 2-9 times higher than those in the NPK and NPKS, respectively. These results indicated a greater potential for N leaching from manure addition and a higher propensity for NO3--N leaching out of the 40-100 cm soil layer. Pearson relationship analysis demonstrated that NO3--N content was clearly affected by SOC and dissolved organic N (DON) contents along the soil profile (20-200 cm), implying that the higher residual NO3--N contents in the deeper soil from manure addition were partially attributable to the mineralization and nitrification of the downward SOC and DON. Interestingly, a low level of residual NO3--N combined with negative mineralization in the 120-200 cm soil layers of the NPKS treatment was observed, suggesting that straw incorporation promotes soil NO3--N retention. Thus, we concluded that long-term manure application is beneficial for soil NO3--N content retention, whereas long term straw incorporation benefits NO3--N retention. PMID- 30292119 TI - Analyses of tetracycline adsorption on alkali-acid modified magnetic biochar: Site energy distribution consideration. AB - As a widely used antibiotic, tetracycline has a huge hidden danger to human health. Municipal sludge rich in organic substances has the potential to produce biochar. In this work, the municipal sludge biochar from solid waste was modified by the alkali-acid binding method, and tetracycline was efficiently removed from the aqueous solution, the adsorption removal efficiency reached to 86% at initial concentration of 200 mg/L. The activation energy was determined by analyzing the adsorption kinetics at different temperatures and tetracycline concentrations. The results showed that tetracycline adsorption on modified biochar was endothermic reaction. Presenting the Langmuir-Freundlich model, adsorption site energy distributions was reckoned. The average adsorption site energy and corresponding standard deviation of the adsorption site energy distribution were deduced emphatically to inquiry the strength of tetracycline adsorption on modified biochar and the adsorption site heterogeneity. The method proposed of research further proves that modified biochar from sewage sludge remove tetracycline from contaminated water has great potential, and exploration of tetracycline adsorption mechanisms by quantifying average site energy. The results and methods of this work can be transferred to study water treatment systems. PMID- 30292120 TI - Implications of meteorological and physiographical parameters on dengue fever occurrences in Delhi. AB - Dengue Fever has become an increasing public health concern around the world due to its serious health consequences including death, lack of effective vaccine and specific treatment. Influence of area specific meteorological and physiographical characteristics on the spread of infectious diseases need to be studied to understand spatial-temporal aspects of infectious diseases in a particular area. Mathematical relationships between various explanatory variables (causative factors) and Dengue Fever incidences have been established to quantify and prioritize the influence of various factors. So that, effective health care services could be provided in these areas. The study successfully explains the occurrences of Dengue Fever in Delhi in term of geo-spatial phenomena/variables. Meteorological data of 13 stations in Delhi at hourly temporal scale for a period 2006-2015 have been used along with multi-spectral satellite data. Data on reported cases of Dengue Fever on daily basis and for a period of ten years from 2006 to 2015 have been obtained for Delhi. Python modules have been developed to extract values of geospatial parameters and to perform Poisson regression. To assess the accuracy of developed Poisson regression based equations, r-squared and error statistics have been calculated. Results indicate strong association of Dengue Fever incidences with temperature, humidity, wind speed, sunshine hours, built-up and vegetation density and distance from dairy locations, waterbodies and drainage network. Further, critical ranges of various parameters favouring high number of Dengue Fever incidences have been determined. These findings have significant public health implications for control and prevention of Dengue Fever incidences in Delhi city and surrounding region. Occurrences of Dengue Fever incidences are found to be highest in the month of September and October. These months represent transition period from rainy season to winter season. It is recommended that further study should focus on detailed analysis of causative factors in this period. PMID- 30292121 TI - Anti-cancer drugs in aquatic environment can cause cancer: Insight about mutagenicity in tadpoles. AB - Cyclophosphamide (Cyc) and 5-fluorouracil (5-FU) are two of the most used antineoplastic drugs (AD) in the world. However, their discharge in the environment became a yet-unknown environmental issue that has impact on some groups of animals, such as amphibians. We assessed tadpoles (Lithobates catesbeianus) exposed to environmental concentrations (EC) of Cyc and 5-FU to evaluate whether they can cause morphological and mutagenic changes in them. We defined the following groups: control, positive control (50 mg/L of Cyc), EC-Cyc I (0.2 MUg/L), EC-Cyc-II (0.5 MUg/L), EF-Cyc (2.0 MUg/L), EC-5-FU-I (13.0 MUg/L), EC-5-FU-II (30.4 MUg/L) and EF-5-FU (123.5 MUg/L). EC groups presented predictive AD concentrations in 10% and 25% hospital-effluent dilutions in water. EF groups met gross hospital-effluent concentrations. Based on our data, ADs caused intestinal changes and influenced the interocular distance in tadpoles after 30 day exposure. We also observed the aneugenic and clastogenic effect of ADs due to the higher frequency of micronucleated and binucleated erythrocytes, and blebbed, multilobulated, notched and kidney-shaped nuclei in animals exposed to them. Based on such changes, we assume that Cyc and 5-FU can trigger malignant cell transformation processes, and cancer, in animals exposed to them, even at low concentrations. Our study is the first to describe that Cyc and 5-FU, spread in the environment, cause damages in non-target organisms opposite to their original end. PMID- 30292122 TI - Development of physical modelling tools in support of risk scenarios: A new framework focused on deep-sea mining. AB - Deep-sea mining has gained international interest to provide materials for the worldwide industry. European oceans and, particularly, the Portuguese Exclusive Economic Zone present a recognized number of areas with polymetallic sulphides rich in metals used in high technology developments. A large part of these resources are in the vicinity of sensitive ecosystems, where the mineral extraction can potentially damage deep-ocean life services. In this context, technological research must be intensified, towards the implementation of environmental friendly solutions that mitigate the associated impacts. To reproduce deep-sea dynamics and evaluate the effects of the mining activities, reliable numerical modelling tools should be developed. The present work highlights the usefulness of a new framework for risk and impact assessment based on oceanographic numerical models to support the adoption of good management practices for deep-sea sustainable exploitation. This tool integrates the oceanic circulation model ROMS-Agrif with the semi-Lagrangian model ICHTHYOP, allowing the representation of deep-sea dynamics and particles trajectories considering the sediments physical properties. Numerical simulations for the North Mid Atlantic Ridge region, revealed the ability of ROMS-Agrif to simulate real deep sea dynamics through validation with in situ data. Results showed a strong diversity in the particle residence time, with a dependency on their density and size but also on local ocean conditions and bottom topography. The highest distances are obtained for the smaller and less dense particles, although they tend to be confined by bathymetric constrains and deposited in deepest regions. This work highlights the potential of this modelling tool to forecast laden plume trajectories, allowing the definition of risk assessment scenarios for deep-sea mining activities and the implementation of sustainable exploitation plans. Furthermore, the coupling of this numerical solution with models of biota inhabiting deep-sea vent fields into ecosystem models is discussed and outlined as cost-effective tools for the management of these remote ecosystems.

AB - Effective management and protection of water resources relies upon understanding how water-quality conditions are changing over time. Water-quality trends for ammonia, chloride, nitrate, sulfate, total dissolved solids (TDS), total nitrogen (TN) and total phosphorus (TP) were assessed at 762 sites located in the conterminous United States between 2002 and 2012. Annual mean concentrations at the start and end of the trend period were compared to an environmentally meaningful level of concern (LOC) to categorize patterns in water-quality changes. Trend direction, magnitude, and the proximity of concentrations to LOCs were investigated. Of the 1956 site-constituent combinations investigated, 30% were above the LOC in 2002, and only six (0.3%) crossed the LOC threshold, either from above or below, indicating that waterquality conditions are not substantially improving, nor are they degrading, in relation to the LOCs. The concentrations of ammonia, nitrate, sulfate, chloride, and TDS tended to be below the LOC, and in cases where the trend was increasing (concentrations approached the LOC from below), the increases were varied and small in magnitude. In contrast, concentrations of TN and TP tended to be above the LOC, and where the trend was decreasing (concentrations approached the LOC from above), the decreases were larger in magnitude and more consistent. These results indicate that if water-quality conditions continue to trend in the same direction, at the same rate, for all sites and constituents studied, elevated concentrations are more likely to drop below an LOC before low concentrations will exceed an LOC.

AB - Scientists, stakeholders and decision makers face trade-offs between adopting simple or complex approaches when modeling ecosystem services (ES). Complex approaches may be time- and data-intensive, making them more challenging to implement and difficult to scale, but can produce more accurate and locally specific results. In contrast, simple approaches allow for faster assessments but may sacrifice accuracy and credibility. The ARtificial Intelligence for Ecosystem Services (ARIES) modeling platform has endeavored to provide a spectrum of simple to complex ES models that are readily accessible to a broad range of users. In this paper, we describe a series of five "Tier 1" ES models that users can run anywhere in the world with no user input, while offering the option to easily customize models with context-specific data and parameters. This approach enables rapid ES quantification, as models are automatically adapted to the application context. We provide examples of customized ES assessments at three locations on different continents and demonstrate the use of ARIES' spatial multi-criteria analysis module, which enables spatial prioritization of ES for different beneficiary groups. The models described here use publicly available global- and continental-scale data as defaults. Advanced users can modify data input requirements, model parameters or entire model structures to capitalize on high resolution data and context-specific model formulations. Data and methods contributed by the research community become part of a growing knowledge base, enabling faster and better ES assessment for users worldwide. By engaging with the ES modeling community to further develop and customize these models based on user needs, spatiotemporal contexts, and scale(s) of analysis, we aim to cover the full arc from simple to complex assessments, minimizing the additional cost to the user when increased complexity and accuracy are needed.

AB - This paper aims to identify the chemical fingerprints of potential PM2.5 sources and estimate their contribution to Thessaloniki port-city's air quality. For this scope, Positive Matrix Factorization model was applied on a comprehensive PM2.5 dataset collected over a one-year period, at two sampling sites: the port and the city center. The model indicated six and five (groups of) sources contributing to particle concentration at the two sites, respectively. Traffic and biomass burning (winter months) comprise the major local PM sources for Thessaloniki (their combined contribution can exceed 70%), revealing two of the major control demanding problems of the city. Shipping and in-port emissions have a non negligible impact (average contribution to PM2.5: 9-13%) on both primary and secondary particles. Road dust factor presents different profile and contribution at the two sites (19.7% at the port; 7.4% at the city center). The secondary particle factor represents not only the aerosol transportation over relatively long distances, but also a part of traffic-related pollution (14% at the port; 34% at the city center). The study aims to contribute to the principal role of quantitative information on emission sources (source apportionment) in port cities for the implementation of the air quality directives and guidelines for public health. PMID- 30292126 TI - Natural regulatory plasma cells. AB - B cells can generate several types of antibody-secreting cells, including plasmablasts that divide and are short lived, as well as plasma cells that do not proliferate and can persist for extended time periods. Here, we discuss the identification of a novel subset of non-dividing plasma cells specialized in the production of interleukin(IL)-10. These cells develop at steady state, including in germ-free mice, via a mechanism dependent on the B cell receptor for antigen and possibly involving the recognition of damaged cells. They are characterized by the expression of the inhibitory receptor LAG-3, and also express CD200, PD L1, as well as PD-L2. Their specialized epigenome allows them to produce IL-10 within hours after stimulation, which altogether qualify these cells as natural regulatory plasma cells. PMID- 30292127 TI - High prevalence of Gammapapillomaviruses (Gamma-PVs) in pre-malignant cutaneous lesions of immunocompetent individuals using a new broad-spectrum primer system, and identification of HPV210, a novel Gamma-PV type. AB - Genus Gammapapillomavirus (Gamma-PV) is the most diverse and largest clade within the Papillomaviridae family. A novel set of degenerate primers targeting the E1 gene was designed and further used in combination with the well-known CUT PCR assay to assess HPV prevalence and genus distribution in a variety of cutaneous samples from 448 immunocompetent individuals. General HPV, Gamma-PV and mixed infections prevalence were significantly higher in actinic keratosis with respect to benign and malignant neoplasms, respectively (p = 0.0047, p = 0.0172, p = 0.00001). Gamma-PVs were significantly more common in actinic keratosis biopsies than Beta- and Alpha-PVs (p = 0.002). The full-length genome sequence of a novel putative Gamma-PV type was amplified by 'hanging droplet' long-range PCR and cloned. The novel virus, designated HPV210, clustered within species Gamma-12. This study provides an additional tool enabling detection of HPV infections in skin and adds new insights about possible early roles of Gamma-PVs in the development of cutaneous malignant lesions.

PMID- 30292129 TI - Insight into carbamazepine degradation by UV/monochloramine: Reaction mechanism, oxidation products, and DBPs formation. AB - UV/monochloramine (NH2Cl) process has attracted some attention for the elimination of contaminants of emerging concern as a novel advanced oxidation process. However, there is still much uncertainty on the performance and mechanisms of UV/NH2Cl process because of its complexity and generation of various species of radicals, including NH2*, HO*, Cl* and other reactive chlorine species (RCS). The mechanism and influence factors of degradation of carbamazepine (CBZ) in the UV/NH2Cl process were investigated, and a synergistic effect was observed. Degradation of CBZ under all investigated conditions followed pseudo-first order kinetics. The corresponding rate constant increased along with the dosage of NH2Cl, and was affected significantly by the presence of bicarbonate and natural organic matter. The process has little pH-dependency, while the specific contribution of RCS and HO* changed with solution pH, and RCS always act as a major contributor to the degradation of CBZ. Eleven byproducts of CBZ were identified and their respective evolution profiles were determined. The participation of UV in chloramination can reduce the formation of nitrogenous DBPs, but promote the formation of carbonaceous DBPs. Furthermore, when influent, sand filtered, and granular activated carbon filtered water was respectively used as background, degradation of CBZ was inhibited to different degree and more disinfection byproducts (DBPs) were generated, compared to deionized water. The electrical energy per order for degradation of CBZ in the UV/NH2Cl process was also calculated to obtain some preliminary cost information. PMID- 30292130 TI - Sustainable production of biomass and biodiesel by acclimation of non-acidophilic microalgae to acidic conditions. AB - The overwhelming response towards algal biodiesel production has been well recognized recently as a sustainable alternative to conventional fuels. Most microalgae cannot grow well at acidic pH. The present study, therefore, investigated whether non-acidophilic microalgae Desmodesmus sp. MAS1 and Heterochlorella sp. MAS3 can be acclimated to extreme-acidic pH for sustainable production of biomass and biodiesel. Growth analysis indicated that both the microalgal strains possessed a passive uptake of CO2 at pH 3.0 with biomass production of 0.25 g dry wt. L-1 in Desmodemus sp. and 0.45 g dry wt. L-1 in Heterochlorella sp.. Flow-cytometry analysis for reactive oxygen species, membrane permeability and neutral-lipids revealed the capabilities of both strains to adapt to the stress imposed by acidic pH. Lipid production was doubled in both the strains when grown at pH 3.0. In-situ transesterification of biomass resulted in 13-15% FAME yield in the selected microalgae, indicating their great potential in biofuel production. PMID- 30292131 TI - High-level production of short branched-chain fatty acids from waste materials by genetically modified Bacillus licheniformis. AB - Short branched-chain fatty acids (SBCFAs) are multi-functional platform chemicals used in many fields. Currently, SBCFAs are produced mainly by chemical synthesis, which is high cost and lead to environmental pollution. The aim of this study was to achieve high-level production of SBCFAs from waste materials, bean dreg and crude glycerol. The Bacillus licheniformis DWc9n* was genetically modified by overexpression of SBCFAs synthesis genes via replacement of native promoter of bkd operon, the mutant strain DWc9n*-PbacA produced 4.68 g/L of SBCFAs, increasing by 1.98-fold compared to wild-type strain. SBCFAs concentration was further increased to 7.85 g/L through process optimization. In a 5-L batch fermenter, the mutant showed SBCFAs production with high concentration (8.37 g/L) and productivity (0.20 g/L/h), which is the highest level of SBCFAs production based on low-value substrates fermentation. This is the first study describing efficient SBCFAs production by the modified B. licheniformis strain from bean dreg and crude glycerol. PMID- 30292133 TI - Aseptic production of citric and isocitric acid from crude glycerol by genetically modified Yarrowia lipolytica. AB - The unconventional yeast Yarrowia lipolytica is known for its capacity to produce citric or isocitric acid from glycerol. In this study a reduction of production cost was achieved by using cheap crude glycerol and conducting the production at pH 3 to prevent bacterial contamination. In this study a Y. lipolytica strain overexpressing Gut1 and Gut2 was used. For the modified strain, crude glycerol proved to be an excellent substrate for production of citric/isocitric acids in aseptic conditions, as the final concentration of these compounds reached 75.9 +/ 1.8 g L-1 after 7 days of batch production. Interestingly, the concentration of isocitric acid was 42.5 +/- 2.4 g L-1, which is one of the highest concentrations of isocitric acid obtained from a waste substrate. In summary, these data show that organic acids can be efficiently produced by the yeast Y. lipolytica from crude glycerol without any prior purification in aseptic conditions. PMID- 30292132 TI - Enhanced performance and hindered membrane fouling for the treatment of coal chemical industry wastewater using a novel membrane electro-bioreactor with intermittent direct current. AB - A membrane electro-bioreactor (MEBR) embracing biological treatment, electrokinetic phenomena and membrane filtration was established by applying intermittent direct current (DC) to MBR. MEBR exhibited significant improvement of treatment performance and reduction of membrane fouling. COD and total phenols removal efficiencies increased to 83.53% and 93.28% at an exposure mode of 24' OFF/6'-ON, compared to 71.24% and 82.43% in MBR. Trans-membrane pressure increment rate declined dramatically in MEBR, which was mainly attributed to the increase of sludge floc size and decrease of zeta potential, soluble microbial products and specific resistance to filtration, resulted from electrokinetic effects such as electrocoagulation, electrophoresis, electroosmosis and electromigration of ions. It was notable that DC exposure exerted distinct evolution on microbial community, with the improvement of microbial community richness and diversity. The relative abundances of functional genera were promoted noticeably in MEBR. An interactive relevance existed among microbial community structure, mixed liquor properties and operational parameters. PMID- 30292134 TI - Reduced nicotinamide adenine dinucleotide phosphate inhibits rat platelet aggregation and p38 phosphorylation. AB - Previous studies found that reduced nicotinamide adenine dinucleotide phosphate (NADPH) protected neurons against ischemia/reperfusion-induced injury. In addition to ROS reduction and ATP increment, preliminary data suggested that NADPH inhibited ADP and thrombin-induced platelet aggregation. As the effect of NADPH on platelet function was not reported by other investigators, the actions of NADPH on platelet function and mechanisms of actions were investigated in the present study. In vitro studies, the effects of different concentrations of NADPH on platelet aggregation induced by ADP (10 MUM), thrombin (0.05 U/mL) or AA (50 MUM) were determined. The results showed that NADPH could inhibit platelet aggregation induced by ADP, thrombin or AA in a concentration dependent manner. When the inhibitory effects of NAD+, NADH, NADP+ and NADPH on platelet aggregation were compared, NADPH demonstrated the relatively best effect on platelet aggregation. In vivo studies, the effects of NADPH on platelet aggregation, tail bleeding time, coagulation response and ferric chloride-induced thrombosis were determined in mice or rats. The maximum aggregation rate of platelets of rats injected with NADPH (5 mg/kg) was lower than platelets from control rats. NADPH transiently prolonged tail bleeding time in mice at 30 min after the injection of NADPH (7.5 mg/kg), while aspirin (15 mg/kg) significantly prolonged the tail bleeding time in mice at all time points examined. NADPH (5 mg/kg), as well as aspirin (10 mg/kg), had no effect on coagulation response in rats. Using a FeCl3-induced abdominal aorta injury thrombosis model, administration of NADPH (5 mg/kg) significantly delayed the onset of vessel occlusion, while aspirin (10 mg/kg) almost completely prevented the vessel occlusion. With microscopic examination the thrombi in injured vessel sections of rats received NADPH were much smaller and less dense than that of rats received vehicle treatment. ADP induced an increase in phosphorylation of p38 and the effect was markedly inhibited by the p38 inhibitor SB203580. Similarly, NADPH also inhibited ADP-induced phosphorylation of p38. Similar to NADPH, SB203580 robustly inhibited ADP- and thrombin-induced platelet aggregation. In addition, NADPH also reduced ADP-induced increases in ROS in platelets. The current results demonstrated that NADPH inhibited platelet aggregation, oxidative stress and p38 phosphorylation, suggesting that NADPH might be a novel compound for management of high risk of cardiovascular disease. PMID- 30292135 TI - Differences in the ease with which mutant viruses escape from human monoclonal antibodies against the HA stem of influenza A virus. AB - BACKGROUND: Broadly protective human monoclonal antibodies that recognize the conserved epitopes in the HA of influenza A virus are being developed as therapeutic agents. Emergence of resistant viruses must always be considered when developing therapeutic agents against influenza. OBJECTIVES: We examined human hetero-reactive mAbs against the HA stem of influenza A virus for the ease with which escape mutant viruses emerged. STUDY DESIGN: We attempted to generate the mutant viruses escaped from the hetero-reactive anti-HA stem antibodies. We also evaluated their protective efficacy, binding affinity, and epitopes. RESULTS: We obtained several human monoclonal antibodies (mAbs) that react with the HA of different HA subtypes of influenza A virus belonging to group 1. Upon attempting to generate escape mutant viruses, we found that the ease with which such viruses emerged differed among the mAbs; viruses barely escaped from two of the mAbs (clones S9-3-37 and F20C77), whereas escape from the third mAb (clone F5B7) occurred readily. Comparisons of the mAbs revealed that the HA stem epitopes, in vitro neutralization potency, binding affinity to H1-HA, and protective efficacy against lethal challenge with H1N1pdm09 virus were all comparable. CONCLUSIONS: These results demonstrate the importance of determining the ease with which escape mutant viruses emerge when evaluating anti-HA stem antibodies as antiviral agents during preclinical testing. PMID- 30292136 TI - Simultaneous determination of seven flavonoids, two phenolic acids and two cholesterines in Tanreqing injection by UHPLC-MS/MS. AB - A new ultra-high performance liquid chromatography combined with triple quadrupole mass spectrometry was developed to evaluate the quality of Tanreqing injection. Seven flavonoids (Rutin, Baicalin, Scutellarin, Chrysin-7-O-Beta-d glucoronide, Oroxylin A-7-O-beta-d-glucoronide, Wogonin, Luteolin-7-O-glucoside), two phenolic acids (Chlorogenic acid, Caffeic acid) and two cholesterines (Ursodeoxycholic acid, Chenodeoxycholic acid) in Tanreqing injection could be measured simultaneously. For the determination of the eleven compounds, the conditions were set as follows: The mobile phase was a gradient of 0.1% aqueous formic acid solution (A) and acetonitrile (B); the flow rate was 0.2 mL min-1, the column was Acquity UPLC HSS T3 column (2.1 mm * 100 mm, 1.8 MUm); and the multiple-reaction monitoring (MRM) with a negative electro spray ionization interface (ESI-) was selected. Within the test ranges, all the standard regression curves showed excellent linear regression (r > 0.99). In terms of (relative standard deviation) RSDs, the precision, repeatability and stability of the eleven compounds were all lower than 3%. The recovery rates of Tanreqing injection and the RSD were 97.8-103.7% and 0.4%-2.0%, respectively. The RSD value was in accordance with the requirements of less than 3.0%. This method has been successfully used in the analysis of Tanreqing injection. In summary, a fast, accurate and reliable UPLC-ESI--MS/MS method was successfully developed for the simultaneous detection of the eleven major active ingredients with different chemical structures in Tanreqing injection, and can be used for the quality control of Tanreqing injection as well. PMID- 30292137 TI - Global lower limb muscle coactivation during walking at different speeds: Relationship between spatio-temporal, kinematic, kinetic, and energetic parameters. AB - Muscle coactivation is the mechanism that regulates the simultaneous activity of antagonist muscles around the same joint. During walking, muscle joint coactivation varies within the gait cycle according to the functional role of the lower limb joints. In the present study, we used a time-varying multi-muscle coactivation function (TMCf) with the aim of investigating the coactivation of 12 lower limb muscles and its relationship with the gait cycle, gait speed (low, self-selected, and fast), ground reaction force, gait variability, and mechanical energy consumption, and recovery in a sample of 20 healthy subjects. Results show that the TMCf is speed dependent and highly repeatable within and between subjects, similar to the vertical force profile, and negatively correlated with energy recovery and positively correlated with both energy consumption and balance-related gait parameters. These findings suggest that the global lower limb coactivation behavior could be a useful measure of the motor control strategy, limb stiffness, postural stability, energy efficiency optimization, and several aspects in pathological conditions. PMID- 30292139 TI - A Novel Aurora-A Inhibitor (MLN8237) Synergistically Enhances the Antitumor Activity of Sorafenib in Hepatocellular Carcinoma. AB - Currently, sorafenib-based therapy is the standard treatment for advanced hepatocellular carcinoma (HCC), and there is a strong rationale for investigating its use in combination with other agents to achieve better therapeutic effects. Aurora-A, a member of a family of mitotic serine/threonine kinases, is frequently overexpressed in human cancers and therefore represents a target for therapy. Here, we investigated a novel Aurora-A inhibitor, MLN8237, together with sorafenib in HCC cells in vitro and in vivo, and elucidated the possible molecular mechanism. Here, it was found that MLN8237 was strongly synergistic with sorafenib in inhibition of HCC progression by altering cell growth, cell cycle regulation, apoptosis, migration, invasion, and angiogenesis. Mechanism dissection suggests that the combination of MLN8237 and sorafenib led to significant inhibition of the activation of phospho-Akt (p-Akt) and phospho-p38 mitogen-activated protein kinase (p-p38 MAPK) and their downstream genes including CDK4, cyclinD1, and VEGFA. The activators of p-Akt and p-p38 MAPK signaling partially reversed the synergistic inhibitory effects of sorafenib and MLN8237 on HCC progression. Subsequent in vivo studies further confirmed the synergistic effects of sorafenib and MLN8237. Collectively, the newly developed sorafenib-MLN8237 combination may be a novel therapy to better inhibit HCC progression. PMID- 30292140 TI - Metformin Protects against H2O2-Induced Cardiomyocyte Injury by Inhibiting the miR-1a-3p/GRP94 Pathway. AB - Ischemia-reperfusion (I/R) injury is a major side effect of the reperfusion treatment of the ischemic heart. Few therapies are available for the effective prevention of this injury caused by the oxidative stress-induced cardiomyocyte apoptosis. Metformin was shown to have a potential cardiac protective effect and ability to reduce cardiac events, but the exact mechanism remains unclear. Here, we aimed to confirm and investigate the mechanisms underlying potential metformin activity against I/R injury in response to oxidative stress. We determined that the expression of miR-1a-3p was significantly increased in neonatal rat ventricular cells (NRVCs), which were exposed to H2O2in vitro and in the hearts of mice that underwent the I/R injury. MiR-1a-3p was shown to target the 3' UTR of GRP94, which results in the accumulation of un- or misfolded proteins, leading to the endoplasmic reticulum (ER) stress. The obtained results demonstrated that C/EBP beta directly induces the upregulation of miR-1a-3p by binding to its promoter. Furthermore, as a direct allosteric AMPK activator, metformin was shown to activate AMPK and significantly reduce C/EBP beta and miR-1a-3p levels compared with those in the control group. In conclusion, metformin protects cardiomyocytes against H2O2 damage through the AMPK/C/EBP beta/miR-1a-3p/GRP94 pathway, which indicates that metformin may be applied for the treatment of I/R injury. PMID- 30292138 TI - Oligonucleotide Aptamer-Mediated Precision Therapy of Hematological Malignancies. AB - Precision medicine has recently emerged as a promising strategy for cancer therapy because it not only specifically targets cancer cells but it also does not have adverse effects on normal cells. Oligonucleotide aptamers are a class of small molecule ligands that can specifically bind to their targets on cell surfaces with high affinity. Aptamers have great potential in precision cancer therapy due to their unique physical, chemical, and biological properties. Therefore, aptamer technology has been widely investigated for biomedical and clinical applications. This review focuses on the potential applications of aptamer technology as a new tool for precision treatment of hematological malignancies, including leukemia, lymphoma, and multiple myeloma. PMID- 30292141 TI - Exon Skipping in a Dysf-Missense Mutant Mouse Model. AB - Limb girdle muscular dystrophy 2B (LGMD2B) is without treatment and caused by mutations in the dysferlin gene (DYSF). One-third is missense mutations leading to dysferlin aggregation and amyloid formation, in addition to defects in sarcolemmal repair and progressive muscle wasting. Dysferlin-null mouse models do not allow study of the consequences of missense mutations. We generated a new mouse model (MMex38) carrying a missense mutation in exon 38 in analogy to a clinically relevant human DYSF variant (DYSF p.Leu1341Pro). The targeted mutation induces all characteristics of missense mutant dysferlinopathy, including a progressive dystrophic pattern, amyloid formation, and defects in membrane repair. We chose U7 small nuclear RNA (snRNA)-based splice switching to demonstrate a possible exon-skipping strategy in this new animal model. We show that Dysf exons 37 and 38 can successfully be skipped in vivo. Overall, the MMex38 mouse model provides an ideal tool for preclinical development of treatment strategies for dysferlinopathy. PMID- 30292142 TI - The Fast Real-time Assessment of Combination Therapies in Immuno-ONcology (FRACTION) program: innovative, high-throughput clinical screening of immunotherapies. AB - BACKGROUND: The unprecedented success of immuno-oncology (I-O) agents targeting the cytotoxic T lymphocyte-associated antigen 4 and programmed death-1/programmed death-ligand 1 pathways has stimulated the rapid development of other I-O agents against novel immune targets. Bristol-Myers Squibb has designed a novel phase II platform trial, the Fast Real-time Assessment of Combination Therapies in Immuno ONcology (FRACTION) Program, to efficiently identify promising combinations for patients with specific malignancies. The concept and study design of the FRACTION Program-currently ongoing in patients with advanced non-small-cell lung cancer (FRACTION-Lung), gastric cancer (FRACTION-Gastric Cancer) and renal cell carcinoma (FRACTION-RCC)-are described. METHODS: The FRACTION Program comprises open-label, phase II studies that use adaptive randomisation designs with rolling combination regimens. Master Protocols provide the overall study design framework, whereas Sub-Protocols introduced over time provide details on specific I-O combination therapies to which patients may be randomised. In a Master Protocol, patients are enrolled into different Study Tracks based on characteristics such as prior I-O therapy experience. Patients who progress may be rerandomised to other combination regimens from any ongoing Sub-Protocol. Primary objectives are to assess objective response rate, median duration of response and progression-free survival rate at 24 weeks; the secondary objective is to investigate safety and tolerability. Biomarker collection before and on treatment will facilitate identification of patient subsets who benefit most from each therapy. CONCLUSIONS: The FRACTION Program allows for the evaluation of multiple I-O combinations through individual studies for specific tumours using an adaptive trial design and continuous enrolment. PMID- 30292143 TI - Predictors of urinary antibiotics in children of Shanghai and health risk assessment. AB - BACKGROUND: An extensive exposure to antibiotics has been confirmed in children, but the predictors and potential health risk remain unclear. OBJECTIVE: To investigate the predictors of antibiotics in urine and potential health risk in children of Shanghai. METHODS: We selected 284 school children aged 8-11 years from a central area of Shanghai, China, in 2017. Ultra-performance liquid chromatography coupled with high-resolution mass spectrometry was used to measure 20 antibiotics, including four human antibiotics (HAs), six veterinary antibiotics (VAs), 10 human/veterinary antibiotics (H/VAs), and three metabolites in first morning urine. Logistic regression model was used to examine the associations of 17 variables related to demographic and socioeconomic factors, recent antibiotic use, drinking water intake, food consumption, and anthropometric measurements with the detection frequency of HAs, VAs, or H/VAs in urine. After daily intake was estimated, health risk was assessed for VAs and H/VAs by using hazard quotient (HQ) and hazard index (HI) based on microbiological or toxicological effects. RESULTS: The detection frequencies of 20 antibiotics and three metabolites ranged from 0 to 27.8% with an overall detection frequency being 56.0%. The detection frequency of HAs increased with age and screen time at weekend. Sex, age, family income and screen time were positively associated with the detection frequencies of VAs and H/VAs. Children reporting antibiotic use in the past three months had a higher detection frequency of HAs. Children with a higher consumption frequency of dairy products had a higher detection frequency of VAs + H/VAs, but a lower detection frequency of HAs. An increased overall detection frequency of all antibiotics was seen in children with higher consumption frequencies of aquatic products, livestock and poultry meat, or milk and dairy products. HQ >1 was only found for ciprofloxacin (5.6%) and ofloxacin (0.4%) based on microbiological effect. HI >1 was found in 6.0% of children for microbiological effect and none was found for toxicological effect. CONCLUSIONS: Predictors for antibiotics in urine for children included sex, age, family income, screen time, clinical use, and animal-derived food consumption. There was potential health risk for children with exposure to antibiotics. PMID- 30292145 TI - Chiral pharmaceuticals: Environment sources, potential human health impacts, remediation technologies and future perspective. AB - Chiral pharmaceuticals (CPs), including non-steroid anti-inflammatory drugs (NSAIDs), beta-blockers and some herbicide and pesticides, are widely used in aquaculture, clinical treatment and many other fields. However, people are increasingly concerned about such ubiquitous pollutants, which can frequently be detected in contaminated soil and water. In large part, the significant sources of chiral pharmaceuticals stem from industrial processes, such as the direct discharge of untreated or incompletely treated wastewaters containing chiral pharmaceuticals, incorrect storage and use, animal wastes and biosolids. The main ways for human exposure to chiral pharmaceuticals are the disease treatment process and chiral pharmaceuticals contaminants. According to the results of a series of toxic studies, some diseases, even cancers, may be associated with exposure to certain chiral pharmaceuticals. Therefore, the treatment of chiral pharmaceuticals has become an important issue. The current advanced remediation techniques for chiral pharmaceuticals include the conventional method (sorption and sonolysis), biotransformation (an aerobic granular sludge-sequencing batch reactor and constructed wetland system) and advanced oxidation processes (ozonation and photocatalysis). Herein, in this review, we summarize the current status and sources of chiral pharmaceuticals, potential effects on human health, as well as the superiority, disadvantages and prospects of current advanced remediation technologies. Moreover, we also anticipate the prospect of the future research needed for chiral pharmaceuticals pollutant remediation. PMID- 30292144 TI - Mortality burden attributable to PM1 in Zhejiang province, China. AB - BACKGROUND: Limited evidence is available on the health effects of particulate matter with an aerodynamic diameter of <1 MUm (PM1), mainly due to the lack of its ground measurement worldwide. OBJECTIVES: To identify and examine the mortality risks and mortality burdens associated with PM1, PM2.5, and PM10 in Zhejiang province, China. METHODS: We collected daily data regarding all-cause (stratified by age and gender), cardiovascular, stroke, respiratory, and chronic obstructive pulmonary disease (COPD) mortality, and PM1, PM2.5, and PM10, from 11 cities in Zhejiang province, China during 2013 and 2017. We used a quasi-Poisson regression model to estimate city-specific associations between mortality and PM concentrations. Then we used a random-effect meta-analysis to pool the provincial estimates. To show the mortality burdens of PM1, PM2.5, and PM10, we calculated the mortality fractions and deaths attributable to these PMs. RESULTS: Daily concentrations of PM1, PM2.5, and PM10 ranged between 0-199 MUg/m3, 0-218 MUg/m3, and 0-254 MUg/m3, respectively; Mortality effects were significant in lag 0-2 days. The relative risks for all-cause mortality were 1.0064 (95% CI: 1.0034, 1.0094), 1.0061 (95% CI: 1.0034, 1.0089), and 1.0060 (95% CI: 1.0038, 1.0083) associated with a 10 MUg/m3 increase in PM1, PM2.5, and PM10, respectively. Age- and gender-stratified analysis shows that elderly people (aged 65+) and females are more sensitive to PMs. The mortality fractions of all-cause mortality were estimated to be 2.39% (95% CI: 1.28, 3.48) attributable to PM1, 2.53% (95% CI: 1.42, 3.63) attributable to PM2.5, and 3.08% (95% CI: 1.95, 4.19) attributable to PM10. The ratios of attributable cause-specific deaths for PM1/PM2.5, PM1/PM10, and PM2.5/PM10 were higher than the ratios of their respective concentrations. CONCLUSIONS: PM1, PM2.5 and PM10 are risk factors of all-cause, cardiovascular, stroke, respiratory, and COPD mortality. PM1 accounts for the vast majority of short-term PM2.5- and PM10-induced mortality. Our analyses support the notion that smaller size fractions of PM have a more toxic mortality impacts, which suggests to develop strategies to prevent and control PM1 in China, such as to foster strict regulations for automobile and industrial emissions.

AB - OBJECTIVES: This study aims to explore the clinical profiles and onset age related difference of executive dysfunctions and behavioral changes in early drug naive patients with Parkinson's disease (PD). METHODS: A cross-sectional analysis on 419 early stage drug-naive PD patients was conducted. The frontal assessment battery (FAB) was used to assess executive functions and the frontal behavioral inventory (FBI) was used to assess behavioral changes. RESULTS: Executive dysfunctions were detected in 113 patients (27.0%), and 219 patients (52.3%) displayed varied degrees of behavioral changes. The most frequent affected domain for the FAB was lexical fluency (31.7%), while the three most frequent affected domains for the FBI were apathy (26.0%), irritability (24.3%) and inattention (20.8%). Compared to the early-onset PD (EOPD) patients, the late-onset PD (LOPD) patients exhibited significantly higher frequent damage in FAB especially similarities, motor series, and conflicting instructions as well as lower frequent damage in lexical fluency. The frequencies of FBI-abnormal were not different between the two groups. Multivariate analyses indicated that age at PD onset was independently associated with FAB total score and its subscores including lexical fluency, motor series, conflicting instructions and go-no go task, but it has no relationship with FBI total score and its subscores. CONCLUSIONS: Executive deficits and behavioral changes are common in the early stage of PD. Age at PD onset is independently associated with the performance of executive functions. However, behavioral changes in PD may be not affected by onset age. PMID- 30292148 TI - Cortical biometals: Changed levels in suicide and with mood disorders. AB - BACKGROUND: Changes in levels of metals have been suggested to contribute to the pathophysiologies of several neurodegenerative disorders but to our knowledge this is the first metallomic study in CNS from patients with mood disorders. The focus of this study was on cortical regions affected by the pathophysiologies of bipolar disorders and major depressive disorders. METHODS: Levels of metals were measured using inductively coupled plasma mass spectrometry in Brodmann's areas (BA) 6, 10 and 17 from patients with major depressive disorders (n = 13), bipolar disorders (n = 12) and age / sex matched controls (n = 13). RESULTS: There were lower levels of cortical strontium (BA 6 & 10), ruthenium (BA 6 & 17) and cadmium (BA 10) from patients with major depressive disorder as well as lower levels of strontium in BA 10 from patients with bipolar disorders. Unexpectedly, there were changes in levels of 16 metals in the cortex, mainly BA 6, from suicide completers compared to those who died of other causes. LIMITATIONS: Cohort sizes were relatively small but comparable with many studies using human postmortem CNS. Like all studies on non-treatment naive patients, drug treatment was a potential confound in our experiments. CONCLUSIONS: Our exploratory study suggests changes in levels of metals in bipolar disorders and major depressive disorders could be affecting cortical oxidative balance in patients with mood disorders. Our data raises the possibility that measuring levels of specific biometals in the blood could be used as a biomarker for increased risk of suicide. PMID- 30292147 TI - Symptoms of social anxiety disorder and major depressive disorder: A network perspective. AB - BACKGROUND: We used network analyses to examine symptoms that may play a role in the co-occurrence of social anxiety disorder (SAD) and major depressive disorder (MDD). Whereas latent variable models examine relations among latent constructs, network analyses have the advantage of characterizing direct relations among the symptoms themselves. METHOD: We conducted network modeling on symptoms of social anxiety and depression in a clinical sample of 130 women who met criteria for SAD, MDD, both disorders, or had no lifetime history of mental illness. RESULTS: In the resulting network, the core symptoms of social fear and depressed mood appeared at opposite ends of the network and were weakly related; so-called "bridges" between these symptoms appeared to occur via intervening variables. In particular, the worthless variable appeared to play a central role in the network. LIMITATIONS: Because our data were cross-sectional, we are unable to draw conclusions about the direction of these effects or whether these variables are related to each other prospectively. CONCLUSIONS: Continued testing of these pathways using longitudinal data will help facilitate the development of more effective clinical interventions for these disorders. PMID- 30292149 TI - Portable and selective colorimetric film and digital image colorimetry for detection of iron. AB - Iron is an important trace element in environmental and biological systems, the development of simple and selective methods for the determination of iron is important. In this work, completely biodegradable tapioca starch was introduced as the substrate to entrap standard chromogenic probes (1,10-phenanthroline) for fabrication of a novel colorimetric sensor for ferrous. A clear plasticized thin film from tapioca starch was fabricated inside a small plastic tube as a portable test kit. A red complex was obtained by exposing the film to a ferrous solution, while no color changes were obtained with various other ions, indicating excellent selectivity. The developed films were applied in conjunction with a digital image colorimetry for quantification of ferrous. Calculated molecular absorption of the red complex showed the widest linear range (0 to 10 mg L-1) with good linearity (R2 < 0.9934) with ferrous concentrations. The developed method provided good inter-day precision (1.75 to 3.97%RSD, 5 days 15 sensors), good accuracy (+2.35% to +4.57% relative error), and low detection limit (0.09 +/ 0.01 mg L-1). The concentrations of ferrous ion in soil and water samples quantified by the developed method were not significantly different from atomic absorption spectrophotometry at 95% confidence level. The films were stable for at least three months. PMID- 30292150 TI - Investigations over optical properties of boron complexes of benzothiazolines. AB - Quantum chemical analyses over benzothiazolines and their boron complexes are performed. In calculations, M06-2X method was selected with 6-31 + G(d,p) level. Structural and spectral (IR and NMR) characterization of studied compounds are done in detail. Quantum chemical descriptors (QCDs) are calculated to investigate the optical properties. Furthermore, molecular electrostatic potential (MEP) maps of the studied compounds are calculated by using electro-static potential (ESP) charges. According to QCDs and MEP maps, NLO properties of boron complexes are more than those of benzothiazolines and (Z)-2-((pyridin-2-ylmethylene)amino) benzenethiolatebutane-1,3-bis(olate)boron(III), complex (7), has the most NLO activity in studied compounds. Finally, solvent effect on NLO activity are investigated by calculating UV-vis spectrum in gas phase (epsilon = 1), toluene (epsilon = 2.3741), chloroform (epsilon = 4.7113), methanol (epsilon = 32.613), water (epsilon = 78.3553) and n-methylformamide-mixture (epsilon = 181.56). According to these spectra results, NLO activity mainly increases with increasing of polarizability of media. PMID- 30292151 TI - Optical spectroscopic properties recorded for simple BOPHY dyes in condensed media: The mirror-symmetry factor. AB - The BOPHY structural scaffold provides opportunities for the synthesis of innumerable derivatives with linear geometries and well-controlled pi-conjugation pathways. The simpler BOPHY chromophores are highly fluorescent but exhibit poor mirror symmetry between absorption and fluorescence spectra at ambient temperature. In particular, the absorption (and excitation) spectra are broad and appear as two overlapping bands of comparable intensity. In constrained media, such as low-temperature rigid glasses or stretched poly(ethylene) films, mirror symmetry is restored. Analysis of the temperature dependence recorded for simple BOPHY derivatives indicates that the vibronic envelope accompanying the electronic transitions can be well described in terms of low- and medium frequency modes. Whereas the fluorescence spectral profile is only weakly dependent on temperature, the excitation spectrum is far more affected. The magnitude of the low-frequency mode, and the associated electron-phonon coupling, increase substantially with increasing temperature and is responsible for temperature broadening and distortion of the excitation spectrum in solution. This critical low-frequency vibronic mode is associated with out-of-plane torsional bending of the BOPHY unit. Variable temperature NMR studies failed to provide unequivocal evidence for conformational changes of one of the derivatives over the temperature range 193-353 K.

AB - The pristine BaTiO3 has been experimentally confirmed to catalyze hydrogen production from water splitting, but the reaction cannot be driven by the visible light because of the wide energy band gap of BaTiO3. To understand the feasibility of the reaction driven by the visible light of the strongest part of the solar energy, we have investigated the effect of different concentrations of oxygen group element dopants on the electronic and optical properties of BaTiO3 by using first-principles density functional theory calculations with meta-GGA + MBJ potential. The formation energy of each doped structure is calculated to examine the feasibility of synthesis in energy. The energy band gaps and the energy positions of conduction and valence bands are calculated and the results reveal that all the structures except the one that doped with 5 at% Te satisfy the conditions of water splitting although the energy band gaps of the doped BaTiO3 decrease obviously. The partial charge distributions of conduct band maximum and valence band minimum are used to demonstrate the electron-hole separation. The absorption coefficients are calculated for all the considered structures. The results demonstrate that the doped chalcogens can significantly enhance the absorption in visible light range, which implies that the doped BaTiO3 are promising to catalyze the hydrogen production from water splitting driven by solar energy. PMID- 30292153 TI - Growing practices and the use of potentially harmful chemical additives among a sample of small-scale cannabis growers in three countries. AB - BACKGROUND: With the growth of legal cannabis markets there has been recognition of the adverse impacts of certain cannabis growing practices, notably, use of harmful chemicals. A major concern has been the use of Plant Growth Regulators (PGRs) which limit plant size and stimulate bud production. These chemicals, many of which have been banned from food crops, have been found unlisted in cannabis growing nutrients sold online or in hydroponic stores. This study describes the cannabis growing practices used by small-scale recreational cannabis growers and specifically their self-reported use of chemicals. METHODS: Web survey data from 1722 current and recent cannabis growers in Australia, Denmark, and the UK, who were asked about their cannabis growing practices, including the use of fertilizers and supplements. RESULTS: Overall 44% of the sample reported using any chemical fertilizers, supplements or insecticides. Logistic regression indicated that the unique predictor of the use of chemicals was growing hydroponically. CONCLUSION: Problems associated with product labeling and uncertainty regarding product constituents made it difficult for growers and the researchers to determine which products likely contained PGRs or other harmful chemicals. There is a need for further research to analyze constituents of chemical products marketed to cannabis growers. PMID- 30292154 TI - Pollution status of marine protected areas worldwide and the consequent toxic effects are unknown. AB - Chemical pollution is considered a factor that may threaten marine protected areas (MPAs), and recent studies have found contamination and associated biological effects in some MPAs. However, organized data on this topic are lacking. This study reviewed the literature on pollution in MPAs in order to compile data, determine whether MPAs are influenced by pollution and, whenever possible, describe how they are being affected by contaminants. The results show that the pollution status is unknown in most MPAs worldwide. When any information is available, it is often insufficient to diagnose the threats to biodiversity or to support further actions. More robust and extensive information is available on a small number of MPAs, and much less information is available regarding the negative effects of pollution. More than 80% of the areas studied exhibited evidence of contamination at potentially toxic concentrations or were found to have a status that produced toxic effects on the biota. The scientific community is encouraged to study pollution in MPAs worldwide. PMID- 30292155 TI - Short- and medium-chain chlorinated paraffins in sediments from the Laizhou Bay area, North China: Implications for transportation from rivers to marine environment. AB - The concentrations of short- and medium-chain chlorinated paraffins (SCCPs and MCCPs) were measured for riverine and marine sediments from the Laizhou Bay area in order to investigate their spatial distributions, possible sources and transport behaviors. Concentrations of SCCPs and MCCPs in riverine sediments varied from 8.4 to 2000 ng g-1 dw and from 1.8 to 3200 ng g-1 dw, respectively. Higher concentrations were found exclusively at industrial sites. Emissions from local factories were the main source of CPs in river sediments of this region. It was 5-22 ng g-1 dw and 6-63 ng g-1 dw with an average value of 11 ng g-1 dw and 9 ng g-1 dw for SCCPs and MCCPs in marine sediments of Laizhou Bay, respectively. In addition to riverine input, ship related emissions are suggested to be another important source of CPs in the Laizhou Bay. MCCPs/SCCPs values and compositional profiles of SCCPs were found to vary along with CP concentrations. A distinct shift to congener groups with shorter carbon chains and lower chlorination from emission sources to remote areas was noticed. The role of log octanol-water partition coefficient (LogKow) values indicated decisive in their transportation from emission sources to remote areas in the Laizhou Bay area. PMID- 30292156 TI - Interactive effects of contamination and trematode infection in cockles biochemical performance. AB - Anthropogenic activities, especially those involving substances that pollute the environment can interfere with bivalve populations, as well as parasitism, a fundamental ecological interaction often neglected. In marine environments, organisms are concomitantly exposed to pollutants and parasites, a combination with synergistic, antagonistic or additive effects representing a potential threat to aquatic communities sustainability. In the present study, Cerastoderma edule (the edible cockle)-Himasthla elongata (trematode) was used as host parasite model. Cockles are worldwide recognized as good sentinel and bioindicator species and can be infected by several trematodes, the most abundant macroparasites in coastal waters. Tested hypotheses were: 1) cockles exposed to increasing parasite pressure will present greater stress response; 2) cockles exposure to arsenic (single concentration test: 5.2 MUg L-1) will change parasite infection success and cockles stress response to infection. Arsenic was used for being one of the most common pollutants in the world and stress response assessed using biochemical markers of glycogen content, metabolism, antioxidant activity and cellular damage. Results showed that intensity of parasite pressure was positively correlated to biochemical response, mainly represented by higher metabolic requirements. Contamination did not affect parasite infection success. Compared to arsenic, trematode infection alone exerted a stronger impact: higher glycogen storage, metabolism and cellular damage and antioxidant activity inhibition. In interaction, parasitism and arsenic reduced hosts metabolism and cellular damage. Therefore, to a certain extent and in a contamination scenario, cockles may benefit from trematode infection, working as a protection for the pollutant accumulation in the organisms, reducing overall ROS production, which can consequently led to less toxic effects. These findings highlighted the deleterious effects of trematode infection in their hosts and showed the importance of including parasitology in ecotoxicological studies. PMID- 30292157 TI - What are the effects of soil treatment procedures (sterilization by gamma irradiation and solvent-assisted spiking) on DDE bioaccumulation by earthworms? AB - Ionizing gamma-irradiation and solvent-assisted spiking are frequently applied to eliminate microbial activity and to induce hydrophobic organic compounds (HOCs) into soil, respectively, when studying the accumulation of chemicals in terrestrial organisms. However, the side-effects that may arise from these treatments on soil-HOC interaction and, subsequently, the kinetics and extents of bioaccumulation are not thoroughly understood. To this end, the accumulation of 1,1-dichloro-2,2-bis(p-chlorophenyl)etylene (p,p'-DDE) by Eisenia andrei was studied in sterilized or unsterilized and freshly spiked (FS) or historically contaminated (HC) soils in parallel with an analysis of aliphatic and hydrophilic soil organic matter (SOM) moieties using mid-infrared diffuse reflectance spectroscopy (DRIFT-S). Irradiation did not impart significant changes on spectral SOM descriptors. In contrast, earthworm inhabitation increased the relative presence of aliphatic moieties to a greater extent than hydrophilic ones, reaching or exceeding pre-treatment levels. Overall, effects on SOM chemistry can be ranked as earthworms > spiking > irradiation. Corresponding changes at the bioaccumulation level were observed for the FS soil (i.e., a 27% reduction in bioaccumulation upon sterilization) but not for the HC soil. This implies that in contrast to the interactions between aged p,p'-DDE and sterilized HC soil, the interactions established between freshly added p,p'-DDE and sterilized FS soil were altered by gamma-irradiation-induced secondary effects alone or in combination with earthworm inhabitation. Thus, although the soil treatment processes studied here should not drastically impact compound bioaccumulation, they should be considered in mechanistic studies where the qualitative and quantitative aspects of compound-soil (organic matter)-earthworm interactions are at the centre of attention. PMID- 30292158 TI - Uptake and transformation of steroid estrogens as emerging contaminants influence plant development. AB - Steroid estrogens are emerging contaminants of concern due to their devastating effects on reproduction and development in animals and humans at very low concentrations. The increasing steroid estrogen in the environment all over the world contrasts very few studies for potential impacts on plant development as a result of estrogen uptake. This study evaluated the uptake, transformation and effects of estradiol (17beta-E2) and ethinyl estradiol (EE2) (0.1-1000 MUg L-1) on lettuce. Uptake increased in leaves and roots in a dose-dependent manner, and roots were the major organ in which most of the estrogen was deposited. The transformation of estrogens to major metabolite and their further reverse biotransformation in lettuce tissue was identified. At low concentrations (0.1 and 50 MUg L-1) estrogens resulted in enhanced photosynthetic pigments, root growth and shoot biomass. Application of higher concentrations of estrogens (10 mg L-1) significantly reduced total root growth and development. This was accompanied by increased levels of hydrogen peroxide (H2O2), and malondialdehyde (MDA), and activities of antioxidant enzymes superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and ascorbate peroxidase (APX). Taken together, these findings suggest that at low concentrations estrogens may biostimulate growth and primary metabolism of lettuce, while at elevated levels they have adverse effects. PMID- 30292159 TI - Comparison of greenhouse and open field cultivations across China: Soil characteristics, contamination and microbial diversity. AB - A national scale survey was conducted to determine an array of inorganic and organic contaminants in agricultural soils from two cultivation modes (greenhouse vs. open field) in 20 provinces across China. The investigated contaminants include organochlorine pesticides (OCPs), phthalate esters (PAEs), polycyclic aromatic hydrocarbons (PAHs), lead (Pb), zinc (Zn), copper (Cu) and cadmium (Cd). The large amounts of agrochemicals used and special cultivation mode in greenhouse caused substantial soil pollution and deterioration of soil quality. Mean concentrations of both OCPs and PAEs in greenhouse soil were approximately 100% higher than those in open field. The pH values were 6.85 +/- 1.04 and 7.34 +/- 0.84 for greenhouse and open field, respectively (p > 0.05). The soil microbial community was predicted to be affected by pollution in greenhouse through the PICRUSt analysis of 16s rRNA sequences. The 12 variables including various chemicals and soil properties together explained 15% of the observed variation in the community composition. In the studied variables, PAEs and lead were the primary factors affecting microbial diversity in greenhouse soils, while pH had the greatest impact on the microbial community in open field soils. These findings enhanced our understanding of the environmental impact and contamination management of greenhouses worldwide. PMID- 30292160 TI - Two-generational reproductive toxicity assessment of 6:2 chlorinated polyfluorinated ether sulfonate (F-53B, a novel alternative to perfluorooctane sulfonate) in zebrafish. AB - As an alternative to perfluorooctane sulfonate (PFOS), 6:2 chlorinated polyfluorinated ether sulfonate (commercial name: F-53B) has been used in the Chinese chrome plating industry for over four decades. It has been increasingly detected in environmental matrices in recent years, causing great concern regarding its potential health risks to humans and wildlife. However, its adverse effects on biota remain largely unknown. To explore the chronic toxicity of F-53B on reproduction, a two-generational study was conducted using zebrafish (Danio rerio). Adult zebrafish (F0 generation) were chronically exposed to different concentrations of F-53B (0, 5, 50, and 500 MUg/L) for 180 d using a flow-through exposure system, with F1 and F2 generations reared without exposure. The reproductive toxicity endpoints were assessed in F0 and F1 adult fish. Results showed that F-53B accumulated in the F0 gonads and transferred to the F1 generation via maternal eggs, and even remained in F1 adult fish and their eggs (F2) after 180 d depuration. In the F0 generation, F-53B exposure significantly inhibited growth and induced reproductive toxicity, including decreased gonadosomatic index and egg production/female, changes in the histological structure of the gonads, and increased serum testosterone levels. In particular, serum estradiol and vitellogenin levels were significantly increased in 5 MUg/L F 53B-exposed adult males. The transcriptional levels of several genes along the hypothalamic-pituitary-gonadal axis were altered in F0 generation fish. Testis transcriptome analysis revealed that F-53B exposure disrupted spermatogenesis in F0 male zebrafish. Maternal transfer of F-53B also induced adverse effects on growth and reproduction in the F1 generation. Furthermore, the higher occurrence of malformation and lower survival in F1 and F2 embryos indicated that parental exposure to F-53B could impair the embryonic development of offspring. Taken together, this study demonstrated that F-53B could induce reproductive toxicity in zebrafish similar to that induced by legacy PFOS, and its potential adverse effects on offspring deserve further investigation. PMID- 30292161 TI - Morpho-physiological and proteomic responses of Aegilops tauschii to imposed moisture stress. AB - Moisture stress is the most important limitation of wheat production in the worldwide. Among the tribe Triticeae, Aegilops tauschii is one of the most valuable gene sources of resistance to abiotic stresses. In order to identify the most tolerant accession to moisture stress, and to understand its adaptive mechanisms at the molecular level, the present experiment was carried out on ten Ae. tauschii accessions under normal (95% soil pot capacity) and moisture stress (45% soil pot capacity) conditions. At the start of the heading time, the expanded flag leaves of treated and untreated plants were sampled for two dimensional electrophoresis (2-DE) based on proteomics approach. A19 accession was less affected by the imposed moisture stress; therefore, it was used for the proteomics experiment. Among 252 protein spots which were reproducibly detected in each given 2-DE gels, 25 spots showed significant differences between the two moisture treatments; 17 spots were upregulated and 8 spots were downregulated. The identified proteins by MALDI-TOF/TOF, were allocated to seven functional protein groups, which were mainly involved in photosynthesis/respiration (28.5%), carbohydrate metabolism (14.2%), energy metabolism (7.1%), chaperone (14.2%), protein translation and processing (14.2%), repair and stability of the genome (7.1%) and unknown function (14.2%). We report this for the first time that RMI2 protein (in the group of repair and stability of the genome) was significantly changed in wheat in response to moisture stress. We believe that, the identified proteins could play important roles in acclimation and tolerance to moisture stress and provide the genetic pathways for improving tolerance to moisture stress in wheat. PMID- 30292162 TI - Interaction of high seawater temperature and light intensity on photosynthetic electron transport of eelgrass (Zostera marina L.). AB - The interaction of widely recognized causes of eelgrass decline (high seawater temperature and limited light intensity) on photosynthetic electron transport was investigated via chlorophyll fluorescence technique. High seawater temperature combined light intensity significantly increasing the relative maximum electron transport rate (rETRmax); at critical temperature of 30 degrees C, the rETRmax increased with the enhancement of light intensity, indicating the elevation of overall photosynthetic performance. Based on the magnitude of effect size (eta2), light intensity was the predominant factor affecting the performance index (PIABS), indicating that photosystem II (PSII) was sensitive to light intensity. Moreover, the donor side was severely damaged as evidenced by the higher decrease amplitude of fast component and its subsequent incomplete recovery. The reaction center exhibited limited flexibility due to the slight decrease amplitude in maximum photochemical quantum yield. In contrast with PSII, photosystem I (PSI) was more sensitive to high seawater temperature, based on the magnitude of eta2 derived from the maximal decrease in slope. High seawater temperature significantly increased PSI activity, plastoquinol reoxidation capacity, and probability for electron transfer to final PSI electron acceptors. Moreover, it combined elevated light intensity significantly stimulated the activity of cyclic electron flow (CEF) around PSI. Higher activity of both PSI and CEF contributed to balancing the linear electron transport via alleviating the over-reduction of the plastoquinone pool, exhibiting flexible regulation of photosynthetic electron transport at critical temperature. Therefore, limited light intensity decreased the tolerance of eelgrass to critical temperature, which might be a factor contributing factor in the observed decline. PMID- 30292163 TI - Bio-priming mitigates detrimental effects of salinity on maize improving antioxidant defense and preserving photosynthetic efficiency. AB - Salinity is an abiotic stress which seriously affects crop production over the world, particularly in arid and semi-arid regions, with harmful effects on germination, growth and yield. Maize (Zea mays L.), cultivated in a wide spectrum of soil and climatic conditions, is the third most important cereal crop after rice and wheat, moderately sensitive to salt stress. A saline level more than 250 mM NaCl damages maize plants, causing severe wilting. In this study, the effects of hydro-priming (distilled water) and bio-priming (Rosmarinus officinalis L. and Artemisia L. leaf extracts) on seed germination and seedling growth of maize, under 100 mM NaCl salinity were investigated. The factorial experiments were carried out in greenhouse under controlled condition (25 degrees C in 12/12 h day/night) based on a completely randomized design with three replicates. Results showed that both hydro- and bio-priming increased germination percentage and germination indexes in maize seeds. Rosmarinus extract was the most effective in inducing salt resistance in 30 days old seedlings, with beneficial effects in the strengthening of the antioxidant system and in the maintenance of a higher photosynthetic efficiency under salt stress condition. PMID- 30292164 TI - The relationship between exclusive breastfeeding and infant development: A 6- and 12-month follow-up study. AB - BACKGROUND: Breastfeeding offers several advantages for infants with research suggesting that it benefits development, including cognitive and language development. However, limited research has examined the benefits in infants under one year. AIMS: To investigate the association between breastfeeding duration and infant development. STUDY DESIGN: A longitudinal study conducted over 12 months. SUBJECTS: Two hundred fifty-five mothers and their infants living in South Korea were seen at three time-points based on infants' age (4, 6, and 12 months). OUTCOME MEASURES: Breastfeeding data were collected at 4 and 6 months. The Korea Developmental Screening Test for Infants & Children was administered at 6 and 12 months to measure developmental milestones. We analyzed the relationship between breastfeeding duration in the first 6 months and infant development at 6 and 12 months using logistic regression analysis. RESULTS: Compared to infants who did not breastfeed at all, infants who were exclusively breastfed until 4 months of age followed by mixed breastfeeding had a better communication and social interaction at 6 months, and better cognition, communication, and social interaction at 12 months. Exclusive breastfeeding until 6 months of age had no apparent impact on the outcomes at 6 and 12 months. CONCLUSIONS: Exclusive breastfeeding up to 4 months of age followed by mixed breastfeeding might maximize the effects of infant development in their first year after birth. Breastfeeding programs should effectively communicate that exclusive breastfeeding for at least 4 months benefits infant development. PMID- 30292165 TI - Perspectives of vaccinators on the factors affecting uptake of meningococcal ACWY vaccine amongst school leavers in London. AB - OBJECTIVES: Uptake of meningococcal ACWY (Men ACWY) vaccine amongst school leavers is suboptimal in London (9.9% compared to 17.4% nationally in 2015/16). This study explores service delivery barriers and elicits insights from general practice staff on their interaction with this cohort. The purpose was to inform the National Health Service England (London) public health commissioning team's strategy to improve Men ACWY vaccination uptake in London. STUDY DESIGN: Qualitative semi-structured interviews study. METHODS: Purposive sampling of practice nurses from three general practices from each of the three London clinical commissioning group areas (Barnet, Camden and Newham) with the largest numbers of 18-20 year old registered patients. Participants were recruited through their practice managers. A thematic analysis approach was used. RESULTS: A total of ten interviews were conducted between June and August 2017. Five themes were identified: (1) Nurses unsupported by practice systems; (2) difficulty getting school leavers into the practice; (3) confused messaging; (4) reliance on parental responsibility for health; and (5) perception of complacency amongst adolescents. CONCLUSION: Little is known about the service factors that impede uptake of adolescent vaccinations. This exploratory study suggests that existing programmatic mechanisms for delivering the Men ACWY catch-up programme were not adequate. The number of adolescent vaccinations offered has increased in the UK in the last five years and is likely to continue. Although the findings need to be further extrapolated in quantitative research, general practice staff need more systematic guidance on their role and how they can support vaccine decision-making in later adolescence. PMID- 30292167 TI - Biochar derived from swine manure digestate and applied on the removals of heavy metals and antibiotics. AB - Swine manure digestate (SMD) is rich of functional groups. In this work, raw biochar (BC) was prepared from SMD by oxygen-limiting pyrolysis, and HCl-BC, NH3 BC and Mn-BC were obtained by modifying BC with HCl, NH3.H2O and KMnO4. The modified biochar was negatively charged and showed a larger specific surface area and total pore volume, and higher contents of Si-O-Si and O-H bonds and aromatic rings with CO bond. Among them, Mn-BC, was given a new Mn-O group. The adsorption capacities of biochar were determined using a model aqueous solution containing some metals and antibiotics. The adsorption experiment results showed that Mn-BC had a quite good capacity for Cu and Zn removal. And the removal efficiency of As (III), sulfadimidine and tylosin of 83.98%, 83.76%, and 77.34% respectively, was also observed by using Mn-BC. Mn-BC was considered to be a promising material for the adsorption of heavy metals and antibiotics. PMID- 30292166 TI - Proton therapy for low-grade gliomas in adults: A systematic review. AB - For adult patients with diffuse low-grade glioma (LGG) proton therapy is an emerging radiotherapy modality. The number of proton facilities is rapidly increasing. However, there is a shortage of published data concerning the clinical effectiveness compared to photon radiotherapy and potential proton specific toxicity. This study aimed to systematically review and summarize the relevant literature on proton therapy for adult LGG patients, including dosimetric comparisons, the type and frequency of acute and long-term toxicity and the clinical effectiveness. A systematic search was performed in several medical databases and 601 articles were screened for relevance. Nine articles were deemed eligible for in-depth analysis using a standardized data collection form by two independent researchers. Proton treatment plans compared favorably to photon-plans regarding dose to uninvolved neural tissue. Fatigue (27-100%), alopecia (37-85%), local erythema (78-85%) and headache (27-75%) were among the most common acute toxicities. One study reported no significant long-term cognitive impairments. Limited data was available on long-term survival. One study reported a 5-year overall survival of 84% and 5-year progression-free survival of 40%. We conclude that published data from clinical studies using proton therapy for adults with LGG are scarce. As the technique becomes more available, controlled clinical studies are urgently warranted to determine if the potential benefits based on comparative treatment planning translate into clinical benefits. PMID- 30292168 TI - The role of the secondary phloem during the development of the grapevine Berry Shrivel ripening disorder. AB - Berry Shrivel (BS) is a post-veraison physiological ripening disorder of grapevine berries. Its symptoms encompass low pH, reduced content of sugars and anthocyanins, and loss of turgor leading to berries shriveling. Evidence for the primary causes of BS is still speculative and anatomical studies are scarce. So far, anatomical studies have determined necrotic cells, degraded primary phloem cells and hardening of secondary phloem cells in the rachis of BS affected grapes. The picture is far from being complete. Herein we report in-depth analyses of the ultrastructure, anatomy and spatial elementary analysis of rachis and pedicel tissues of BS symptomatic grape clusters with different symptom severity. We hypothesize that structural changes in the vascular system of BS affected grape clusters could alter transport functions of the phloem tissue and contribute to the appearance of BS symptoms. By applying different microscopic techniques (LM, SEM, TEM and EDS) we found a number of anatomical differences in both, rachis and pedicels, between H and BS symptomatic grapes, which include: (i) extended areas of collapsed cells and cell wall thickenings in the secondary phloem in BS samples; (ii) reduced number of cell layers in the cambium in BS samples; (iii) higher rate of callose deposition on sieve plates that are additionally covered with a carbohydrate-like material in BS samples; and (iv) reduced (up to 60%) estimated sieve tube conductivity in BS samples.

AB - The application of high performance liquid chromatography (HPLC) to separate explosive chemicals was investigated by molecular dynamics (MD) simulations. The explosive ingredients including NG, RDX, HMX and TNT were assigned as solutes, while methanol (CH3OH) and acetonitrile (CH3CN) were assigned as solvents in the solution system. The polymeric-molecular siloxanes (SiC8) and poly-1,2 methylenedioxy-4-propenyl benzene (PISAF) compounds were treated as stationary phase in the simulation. The simulation results showed that the different species of explosive ingredients were separated successfully in the solutions by each of the constructed stationary phase of SiC8 and PISAF after a total simulation time of 12.0 ps approximately, which were consistent with the experimental analysis of HPLC spectra. The origin for the separation was found due to the electrostatic interactions between polymer and explosives.

AB - The presence and progression of neuromuscular pathology, including spasticity, Duchenne's muscular dystrophy and hyperthyroidism, has been correlated with changes in the intrinsic mechanical properties of skeletal muscle tissue. Tools for noninvasively measuring and monitoring these properties, such as Magnetic Resonance Elastography (MRE), could benefit basic research into understanding neuromuscular pathologies, as well as translational research to develop therapies, by providing a means of assessing and tracking their efficacy. Dynamic elastography methods for noninvasive measurement of tissue mechanical properties have been under development for nearly three decades. Much of the technological development to date, for both Ultrasound (US)-based and Magnetic Resonance Imaging (MRI)-based strategies, has been grounded in assumptions of local homogeneity and isotropy. Striated skeletal and cardiac muscle, as well as brain white matter and soft tissue in some other organ regions, exhibit a fibrous microstructure which entails heterogeneity and anisotropic response; as one seeks to improve the accuracy and resolution in mechanical property assessment, heterogeneity and anisotropy need to be accounted for in order to optimize both the dynamic elastography experimental protocol and the interpretation of the measurements. Advances in elastography methodology at every step have been aided by the use of tissue-mimicking phantoms. The aim of the present study was to develop and characterize a heterogeneous composite phantom design with uniform controllable anisotropic properties meant to be comparable to the frequency dependent anisotropic properties of skeletal muscle. MRE experiments and computational finite element (FE) studies were conducted on a novel 3D-printed composite phantom design. The displacement maps obtained from simulation and experiment show the same elliptical shaped wavefronts elongated in the plane where the structure presents higher shear modulus. The model exhibits a degree of anisotropy in line with literature data from skeletal muscle tissue MRE experiments. FE simulations of the MRE experiments provide insight into proper interpretation of experimental measurements, and help to quantify the importance of heterogeneity in the anisotropic material at different scales.

AB - In response to stress, cancer cells generate nutrients and energy through a cellular recycling process called autophagy, which can promote survival and tumor progression. Accordingly, autophagy inhibition has emerged as a potential cancer treatment strategy. Inhibitors targeting ULK1, an essential and early autophagy regulator, have provided proof of concept for targeting this kinase to inhibit autophagy; however, these are limited individually in their potency, selectivity, or cellular activity. In this study, we report two small molecule ULK1 inhibitors, ULK-100 and ULK-101, and establish superior potency and selectivity over a noteworthy published inhibitor. Moreover, we show that ULK-101 suppresses autophagy induction and autophagic flux in response to different stimuli. Finally, we use ULK-101 to demonstrate that ULK1 inhibition sensitizes KRAS mutant lung cancer cells to nutrient stress. ULK-101 represents a powerful molecular tool to study the role of autophagy in cancer cells and to evaluate the therapeutic potential of autophagy inhibition. PMID- 30292172 TI - Brain injury and adverse outcomes: a contemporary review of the evidence. AB - Recently, research focusing on the implications of brain injuries for deleterious outcomes spanning a wide range of developmental domains has flourished. Findings from this literature suggest that brain injury is a potent source of risk for negative outcomes including neurodegenerative diseases, cognitive impairment, behavioral problems, and psychiatric diagnoses. Despite this evidence, few studies have examined the extent to which these findings represent a causal relationship. This review outlines the expansive literature in this developing area and provides a discussion of potential threats to internal validity. Finally, suggestions for future research are provided with a particular emphasis on leveraging existing findings to better understand the role of brain injury in the development of deleterious outcomes. PMID- 30292174 TI - A Mystery of Patent Ductus Arteriosus and Serum Osmolality in Preterm Infants. AB - OBJECTIVE: Patent ductus arteriosus (PDA) is an important clinical problem associated with mortality and serious morbidities. It is thought that serum osmolality may affect ductal patency. We aimed to investigate the importance of serum osmolality related to ductal patency in preterm infants. STUDY DESIGN: Our study was conducted between January 2013 and December 2017. Premature infants, birth weight <1,500 g and gestational age <32 weeks were included in the study. Serum osmolality was compared between infants with hemodynamically significant PDA (hsPDA) and non-hsPDA. RESULTS: During the study period, 799 patients were evaluated. Mean serum osmolality levels were higher in the "hsPDA" group (297 +/- 10.9 vs. 292 +/- 8.3 mOsm/L) (p = 0.001). The area under the curve for osmolality was 0.582 (p = 0.0006, 95% confidence interval: 0.541-0.622) at the time of diagnosis for predicting hsPDA, with a cutoff value for osmolality of 300 mOsm/L. CONCLUSION: Serum osmolality may be recognized as an important contributing factor for ductal patency especially among extremely preterm infants who are most likely to have hsPDA in the early days of life. PMID- 30292173 TI - Matched-Pair Analysis of Local Infiltration Analgesia in Total Knee Arthroplasty: Patient Satisfaction and Perioperative Pain Management in 846 Cases. AB - In the recent past, numerous studies evaluating local infiltration analgesia (LIA) with controversial results have been reported. Efforts have been made to improve patients' outcome regarding operation techniques and material, as well as pain management and anesthetic methods. In this study, postoperative pain management and patient satisfaction were evaluated in patients undergoing total knee replacement surgery with or without intraoperative LIA. Within the context of the "Quality Improvement in Postoperative Pain Management" (QUIPS) project, parameters were collected on the first postoperative day. All patients included in this study underwent primary knee replacement surgery with general anesthesia. Parameters were compared after performing a 1:1 matched-pair analysis within 14 orthopaedic departments. Pain levels and pain management satisfaction were measured using the numerous rating scales, and pain medication use was compared. From 2010 to 2015, 2,789 patients who underwent primary knee arthroplasty with general anesthesia were evaluated within the project, of whom a total of 846 patients could be compared after performing a matched-pair analysis. Pain scores were significantly better in the LIA group (p = 0.019 for activity pain, p = 0.043 for maximum pain, p < 0.001 for minimum pain), but pain management satisfaction was not superior (p = 0.083). Patients with LIA required less opioids in the recovery room (p = 0.048), while nonopioid medication did not differ significantly (p = 0.603). At the ward, 24 hours postoperatively, no significant difference in the use for nonopioids (p = 0.789) could be measured, whereas patients in the LIA group received significantly more opioids (p < 0.001). Although LIA achieved improvement in pain score outcome, and a comparable patient satisfaction level in the immediate postoperative course, the use of LIA in knee arthroplasty, controversially discussed in the current literature, was not able to reduce the need for opioid pain medication in this study. PMID- 30292175 TI - The Association between Maternal Height, Body Mass Index, and Perinatal Outcomes. AB - OBJECTIVE: To test the hypothesis that maternal height is associated with adverse perinatal outcomes, controlling for and stratified by maternal body mass index (BMI). STUDY DESIGN: This was a retrospective cohort study of all births in California between 2007 and 2010 (n = 1,775,984). Maternal height was categorized into quintiles, with lowest quintile (<=20%) representing shorter stature and the uppermost quintile (>=80%) representing taller stature. Outcomes included gestational diabetes mellitus (GDM), preeclampsia, cesarean, preterm birth (PTB), macrosomia, and low birth weight (LBW). We calculated height/outcome associations among BMI categories, and BMI/outcome associations among height categories, using various multivariable logistic regression models. RESULTS: Taller women were less likely to have GDM, nulliparous cesarean, PTB, and LBW; these associations were similar across maternal BMI categories and persisted after multivariable adjustment. In contrast, when stratified by maternal height, the associations between maternal BMI and birth outcomes varied by specific outcomes, for example, the association between morbid obesity (compared with normal or overweight) and the risk of GDM was weaker among shorter women (adjusted odds ratio [aOR], 95% confidence interval [CI]: 3.48, 3.28-3.69) than taller women (aOR, 95% CI: 4.42, 4.19-4.66). CONCLUSION: Maternal height is strongly associated with altered perinatal risk even after accounting for variations in complications by BMI.

AB - Hydrogen sulfide (H2 S) is a gaseous mediator in various physiological and pathological processes, including neuroimmune modulation, metabolic pathways, cardiovascular system, tumour growth, inflammation and pain. Now the hydrogen polysulfides (H2 Sn ) have been recognised as signalling molecules modulating ion channels, transcription factors and protein kinases. Transient receptor potential (TRP) cation channels can be activated by mechanical, thermal or chemical triggers. Here, we review the current literature regarding the biological actions of sulfide and polysulfide compounds mediated by TRP channels with special emphasis on the role of TRPA1, best known as ion channels in nociceptors. However, the non-neuronal TRPA1 channels should also be considered to play regulatory roles. Although sulfide and polysulfide effects in different pathological circumstances and TRPA1-mediated processes have been investigated intensively, our review attempts to present the first comprehensive overview of the potential crosstalk between TRPA1 channels and sulfide-activated signalling pathways. PMID- 30292177 TI - [Plasma Mass Spectrometry of Sea Mountain Basalts in the Western Pacific and Its Geological Significance]. AB - As a kind of spectroscopic technique, the remote laser-induced breakdown spectroscopy (Remote LIBS) can qualitatively or quantitatively measure the elemental compositions of remote targets with high-power laser and focusing optical path. In this work, a Remote LIBS system was designed and established to probe the target from 2 to 10 meters. It is characterized with Cassegrain telescope structure and automatic focusing technique. Based on this system, a method to remotely retrieve the major elemental abundance of rocks is presented. With comparative experiment, the influences on spectral signal by pulse laser energy, acquisition delay time, integration time, accumulative pulse number are analyzed to find out the optimum parameters: the wavelength of laser is 1 064 nm, pulse energy is 120 mJ, delay time is 1.5 MUs, integration time is 1 ms, and each spectrum data acquired with averaging 30 times detection. 48 pieces of rock specimens and 6 kinds of standard rock samples (shale, granite, andesite, basalt, gneiss and pegmatite) are selected for the experiment. As to the atomic spectra database, 8 characteristic spectral lines of the major elements (SiI390.55 nm,AlI394.40 nm,AlI396.15 nm, Ca II 396.85 nm,FeI404.6 nm,SiI500.60nm,MgI518.36nm,NaI589.59 nm) were extracted for analyses. Then a PLS model is constructed to quantitatively analyze the rock elements. 48 rock specimens were selected as the training sets to serve the model. The 6 standard samples were used to test the solved model. The testing results shows that the elemental abundance of Si and Al can be predicted accurately with average relative error of only 9.4% and 9.6% respectively. PMID- 30292178 TI - [Plasma Mass Spectrometry of Sea Mountain Basalts in the Western Pacific and Its Geological Significance]. AB - Seamount basalts recorded important information of seamount and deep evolution process. Through the analysis of petrology and REE geochemical characteristics of Govorov Guyot, Niulang Guyot, Arnold Guyot, Skornyakova Guyot, Gordin Guyot, McDonnell Guyot, Lingyi Seamount, Xufu Seamounts basalts in the western Pacific, it shows that basalts in study area have amygdaloidal, fumarolic-amygdaloidal and porphyritic texture. Rocks are mainly composed of phenocrysts and matrix. Mineral composition of phenocrysts is mainly plagioclase, olivine and clinopyroxene. Mineral composition of matrix is plagioclase, olivine, clinopyroxene and glassy etc. REE patterns and parameters of each sea mountain basalts reflect the typical characteristics of oceanic island basalts. It indicates that the seamount in study area is a typical volcanic seamount in plate caused by multiple hotspots. At the same time, it may have been influenced by multi-stage fault and magmatic activity. PMID- 30292179 TI - [Determination of Impurity Elements in Rosin with Inductively Coupled Plasma Mass Spectrometry]. AB - An analytical method for the content determining of impurity elements in rosin was established. After being dissolved and diluted in ethanol, the rosin was analyzed directly with inductively coupled plasma mass spectrometry (ICP-MS). Some experiment conditions were optimized, such as the RF power, carrier gas flow, sample amount, and increase the temperature of plasma center channel, to improve the ionization efficiency. Proper oxygen concentration was added in plasma to make sure organic carbon been complete burned, resulting in carbon deposits eliminate and signal stable. Though equipment turn and isotopes selection can effectively eliminate interferences caused by oxide and doubly charged ions mass spectrums. A large amount of isobars and polyatomic ion interference were avoided. The collision reaction cell (CRC) technology was used to further eliminate the mass spectra interference, with He collision model and H2 reaction model, respectively. The results showed that detection limits of different impurity elements were within the range from 0.002 to 0.035 MUg.g-1, and the recoveries of real added sample were between the range from 94.00% to 106.00%, and relative standard deviation is less than 3.34%. This method enables to detect rosin dissolved in ethanol directly and needs no special sample preparation equipment. This simple, fast and accurate approach provides us a new analysis method for the quality valuation of impurity elements in rosin.

AB - In order to research the effect of X-ray fluorescence (XRF) analysis on the results in the sample's micro particles, MCNPX models had been established for an X-ray fluorescence analyzer in this paper. It had studied the characteristics of the samples with different particle sizes, the fluorescence peak counts, the peak to total ratios and the peak to source ratios. A micro particle analysis experiment had been designed for its verification. The results showed that: as for the relationship between the fluorescence intensity and the particle sizes, the MCNPX calculations were consistent with the theoretical, but contrary with the experimental results; the reason is that some hypotheses about samples in the MCNPX models were contrary with the actual states; the samples were crushed by grinding to small particles and tableting process, the MCNPX calculations and experimental results can be conversion; when the particle sizes of the samples reached the certain sizes, the fluorescence peak counts, the peak to total ratios and the peak to source ratios were stable value; within a particular size range, the influence of the particle size effects cannot be ignored, otherwise this influence can be ignored. The research methods and conclusions in this paper can provide a technical reference guide for X-ray analysis in practices. PMID- 30292181 TI - [Development and Output Characteristics of 785 nm Portable Grating-Coupled External Cavity Tunable Semiconductor Laser]. AB - Aiming at the miniaturization requirement of shifted excitation Raman spectroscopy test system, a portable grating-coupled external cavity (EC) tunable semiconductor laser in Littrow configuration is designed and fabricated with a commercial 785 nm high-power laser diode as the gain device. By using a new wavelength tuning method, aiming to change the position of gain device relative to the collimating lens in the horizontal direction, a miniaturized device with the size of 140 mm*65 mm*50 mm is designed. Compared to the traditional wavelength tuning method which is to change the light incident angle by rotating the diffraction grating, this new tuning method reduces the translational distance of semiconductor gain device effectively, thus it is conductive to the fast and broad wavelength tuning of portable EC laser. The experimental results show that the EC laser has a wide wavelength tuning range. Under any injection current from 340 to 900 mA, a wavelength tuning range of more than 10 nm can be realized. Especially at 900 mA, good performance including a 11.67 nm-wavelength tuning range from 779.40 to 791.07 nm, a less than 0.2 nm-spectral linewidth, an up to 280 mW-output power, and a more than 25 dB-amplified spontaneous emission suppression ratio is presented, which fully meets the basic testing requirements of shifted excitation Raman spectroscopy. Moreover, 1.35 nm-electric wavelength tuning range is achieved by applying a mini-piezoelectric actuator. This indicates that the home-made 785 nm portable grating-coupled EC tunable semiconductor laser is suitable as the light source of portable shifted excitation Raman spectroscopy testing system to eliminate the fluorescence background of Raman spectrum. PMID- 30292182 TI - Discrimination of GMOs Using Terahertz Spectroscopy and CS-SVM. AB - This paper develops an effective identification method to discriminate genetically modified (GM) and non-GM organisms. The method is proposed based on terahertz (THz) spectroscopy and support vector machines optimized by Cuckoo Search algorithm (CS-SVM). In this study, the THz spectra of three GM and non-GM soya seed samples were obtained by using terahertz time-domain spectroscopy (THz TDS) system between 0.2 and 1.2 THz. Then, the SVM model is employed to distinguish GM and non-GM soya seeds, in which the two crucial parameters, including the penalty factor and kernel parameter, are optimized by CS algorithm. The experimental results show that THz spectroscopy combined with CS-SVM can provide a rapid, reliable and non-invasive method for GMOs and non-GMOs discrimination. PMID- 30292183 TI - Direct Evidences of Shallow Donor Level Enhanced Green Emission in ZnO Quantum Dots. AB - ZnO Quantum dots with particle sizes about 5 nm were prepared by sol-gel method, the research about the photo luminescence(PL)/photoluminescence excitation(PLE) spectrum and the fluorescence lifetime indicated that the green emissions can be divided into two parts which were attributed to different transit mechanisms. The higher energy green emission was due to the electrons transit from conduction band to oxygen vacancies while the lower energy green emission was assigned to the electrons transit from the shallow donor levels which enhanced the green emission to the oxygen vacancies and the shallow donor levels was also the reason why the green emission reach strongest intensity when the excitation energy was a little lower than the band gap energy. While the blue emission can be explained by the electrons transiting from Zinc intervals to the valence band. The two mechanisms of green emission are first highlighted and should be considered in the optical application. PMID- 30292184 TI - Effect of the Nitrogen Incorporation on the Microstructure and Photoelectric Properties of N Type Nanocrystalline Silicon Thin Films. AB - N type silicon-rich nanocrystalline-SiN(x) ? H films were prepared by plasma enhanced chemical vapor deposition technique by changing NH3 flow rate. The effect of nitrogen incorporation on the microstructure and photoelectric properties of the thin films were characterized by Raman, Fourier transform infrared spectroscopy, ultraviolet-visible absorption spectra, and Hall effect measurement. The results indicated that with the increasing NH3, a phase transition from microcrystalline to amorphous silicon occured. Transmission electron microscope observation revealed that the size of silicon quantum dots could be adjusted by varying the flow rate of NH3. The microstructure order of the films reduced with increasing the flow rate of NH3, while the optical band gap increased, and the optical band tail became narrow. Meanwhile, Si-N bonds density increased and P doping was blocked. I-V testing results showed that with increasing NH3, the conductivity of films first decreased compared with nanocrystalline-Si and then increased. These behaviors reveal a competition in the mechanisms controlling the conductivity. However, with further increasing NH3, the conductivity decreased significantly due to rapid carrier recombination on the amorphous net structure.

AB - The pyrazoline was chosen as the luminescent functional group, and then four kinds of new polyamide polymer blue fluorescent materials were designed and synthesized. The structures of them were confirmed by using NMR (H 1NMR) and gel permeation chromatography (GPC). Furthermore, liquid and solid film fluorescence excitation and emission spectra of the compounds were measured, and three polymers J1, J2 and J3 showed good fluorescence properties. The polymeric materials showed good film capacity, low cost and good thermal stability, and are expected to be widely applied in electroluminescent devices. PMID- 30292186 TI - Study on Molecular Recognition of Cucurbit[6]uril with Oxytetracycline Molecules by Spectroscopic Methods. AB - The molecular recognition of Cucurbit[6]uril (CB[6]) with Oxytetracycline (OTC) was studied by fluorescence spectra and UV spectra. The results showed that the fluorescence intensity and the UV absorbance of OTC were enhanced as host molecules were added, which showed that CB[6] and OTC were interacted. The inclusion of OTC was detected by fluorescence spectra and UV spectra with an apparent 1?1 interaction, which was also observed through the Benesi-Hildebrand method, OTC can form 1?1 complex with CB[6] under acid condition and it can not form complex with CB[6] under basic condition. The thermodynamic parameters (stability constants Ks, Gibbs free energy change DeltaG, enthalpy change, and entropy change) for the complexation process were determined. The thermodynamic studies indicated that the inclusion reactions between CB[6] and OTC were the hydrophobic interaction and endothermic process. PMID- 30292187 TI - Determination of Pb, Cr, Cd, and As in Aluminum-Plastic Packaging Materials via Inductively Coupled Plasma-Mass Spectrometry with Microwave Digestion. AB - Microwave digestion was performed to study the pretreatment methods of aluminum plastic packaging materials (APPMs). Five different digestion reagent combinations and proportions were thoroughly considered. Digestion results indicated that the most suitable reagent combination was sulfuric and nitric acids with the optimal proportion of 1?7 after the orthogonal experiment. Moreover, the possible reasons of the experimental phenomenon were analyzed. The contents of Pb, Cr, Cd, and As in APPMs were subsequently determined via inductively coupled plasma-mass spectrometry (ICP-MS). The satisfactory linearity of calibration curves was obtained with the linear correlation coefficients above 0.999 5, and the instrument detection limits of Pb, Cr, Cd, and As for the current method were 0.215, 0.067, 0.006 and 0.020 ng.mL-1, respectively. Furthermore, the recoveries of standard addition ranged from 83.8% to 111.6%, and the relative standard deviations ranged from 0.5% to 7.4%. Two independent parallel determination results of Pb, Cr, Cd, and As in APPMs were approaching, and the student's t-test (confidence level, alpha=0.05) showed that the determination results had no significant differences. In conclusion, the present method exhibited fine linearity, low detection limit, high recovery, and good precision, which can accurately be utilized to analyze Pb, Cr, Cd, and As elements in APPMs or other similar materials. PMID- 30292188 TI - Improving the Accuracy of Camera-Based Heart Rate Measurement. AB - The heart rate (HR) measurements based on the camera (visible light) can be used to detect HR in non-contact mode, which has great application prospects both in the clinical application and home health care. However, CMOS sensors equipped with "rolling shutters", which distinguishes different lines per frame to become light sensitive at different moments in time, and stylized dithering of image acquisition (IMAQ) time caused by different computer programs running in the background will greatly influence the accuracy of the measured HR. In this paper, we analyze the phase error caused by CMOS sensor and the system error introduced by system sampling clock jitters. According to derivation, we propose two methods, amplitude-frequency superposition and a cubic spline interpolation reconstruction method based on actual schedules, that can be widely utilized in computer vision to overcome the camera phase error and sampling time fluctuation error. Amplitude of signal is analyzed and processed in amplitude-frequency domain in the method of amplitude-frequency superposition, which ignores the signal phase. Thus it can eliminate the phase error effectively. The cubic spline interpolation reconstruction method based on actual schedules can reconstructed the non-uniform sampling of images as uniform ones, so it can eliminate the system error involved by the system clock jitters. What's more, the properties of the methods are tested by applying them to both simulation experiments and real HR measurements. In the simulation, amplitude of measured signal is improved 4.58% relative to the amplitude measured without the method of amplitude frequency superposition; root mean square error of signal's frequency, detected by the cubic spline interpolation reconstruction method based on actual schedules, is reduced more than 30%. In the real HR measurements, the amplitude of HR is raised to 33.5% relatively based on amplitude-frequency superposition. And the accuracy of HR is raised to approximately 40% by the method of cubic spline interpolation reconstruction method based on actual schedules. Therefore, the simulation experiments and real HR measurement proof that we can effectively eliminate the camera phase error based on the amplitude-frequency superposition extraction method, and the cubic spline interpolation based on the timetable method can effectively reduce the random error in IMAQ due to system clock jitters. These methods can both be widely used in dynamic signal detection based on machine vision. PMID- 30292189 TI - The Laser Rangefinder System in Quadrature Modem and Ambiguity Resolution. AB - We propose a laser rangefinder system based on the quadrature modem to achieve amplitude modulation, the method improves the accuracy of the phase measuring and simplifies the hardware design compared to the system with the secondary mixing methods, and to solve the range ambiguity caused by the measuring process, the ranging ambiguity resolving algorithm based on the over-determined equation is proposed, which avoids the searching of the optimal solution, finally the two K60 laser rangefinders and three proposed rangefinders were experimented on the national standard baseline with the precision of 0.18 mm. the measuring time of the proposed system is less than 1.8 s, the average measuring error of those three prototypes is less than 2 mm, and the standard deviation is less than 1 mm within the measuring range 0~60 m. The experimental results show that the proposed design system of the rangefinder has higher measurement accuracy and speed in comparison with the traditional ones, which indicates the high reliability of the proposed design system. PMID- 30292190 TI - Supersonic jet spectroscopy of parent hemiporphycene: Structural assignment and vibrational analysis for S0 and S1 electronic states. AB - Hemiporphycene (HPc), a constitutional isomer of porphyrin, is studied under supersonic expansion conditions by means of laser-induced fluorescence, visible visible hole-burning experiments, single vibronic level fluorescence techniques, and quantum chemical calculations. Only one trans form of jet-cooled HPc is observed, in contrast to solution studies that evidence a mixture of two trans tautomeric forms separated in energy by ~1 kcal/mol. Reliable structural assignment is provided by simulating absorption and emission patterns at the density functional theory and time-dependent density functional theory levels of theory. The vibronic spectra are nicely reproduced for both electronic ground and lowest excited singlet states for the most stable trans form. In contrast to another porphyrin isomer, porphycene (Pc), no tunneling or photo-induced hydrogen transfer is detected. The lower symmetry of HPc compared with Pc and the concomitant non-equivalent positions of the inner-cavity nitrogen atoms result in a non-symmetric double minimum potential for tautomerization, larger energy barrier, and a longer tunneling distance, with the average intramolecular hydrogen bond length larger in HPc than in Pc. HPc readily forms hydrates that show red-shifted absorption relative to the bare molecule. PMID- 30292191 TI - Dissociation of GaN2+ and AlN2+ in APT: Electronic structure and stability in strong DC field. AB - We investigate from a theoretical point of view the stability of AlN2+ and GaN2+ dications produced under high static electric fields like those reached in Atom Probe Tomography (APT) experiments. By means of quantum chemical calculations of the electronic structure of these molecules, we show that their stability is governed by two independent processes. On the one hand, the spin-orbit coupling allows some molecular excited states to dissociate by inter-system crossing. On the other hand, the action of the electric field lowers the potential energy barrier, which ensures the dication stability in standard conditions. We present a detailed example of field emission dynamics in the specific case of the 11Delta states for a parabolic tip, which captures the essentials of the process by means of a simplified model. We show that the dissociation dynamics of AlN2+ and GaN2+ is completely different despite the strong resemblance of their electronic structure. PMID- 30292192 TI - Electronic structure and intramolecular interactions in three methoxyphenol isomers. AB - Electronic structures and intramolecular interactions of three methoxyphenol positional isomers and their rotamers have been studied using core X-ray photoelectron spectroscopy and quantum mechanical calculations. The structural calculations are benchmarked against published calculations of enthalpy of formation and rotational constants, and published experimental data. The good agreement obtained confirms the accuracy of the results. A single rotamer of each isomer was then selected and the C 1s photoelectron spectra calculated and compared with experiment. Good agreement is obtained, and the calculations were extended to investigate the effects of conformation. For 3-methoxyphenol, the difference in the C 1s binding energy of the conformers is small, <0.15 eV. For 2 methoxyphenol, whose ground state includes an OH?OCH3 hydrogen bond, the higher energy rotamers show the largest shifts for the methyl carbon atom, whereas the ring carbon bonded to OH hardly shifts The theoretical differences in core level energies of the two rotamers of 4-MP are still smaller, <0.05 eV. By comparing calculations neglecting or including final state relaxation upon ionization, the relaxation energy of the phenyl carbons in all isomers is found to be ~0.5 eV, while that of the methyl groups is ~1.3 eV.

AB - Using first-principles calculations, we studied the adsorption of alkali ions in pure silica Linde Type A (LTA) zeolite. The probability of adsorbing alkali ions from solution and the driving force for ion exchange between Na+ and other alkali ions at the different adsorption sites were analyzed. From the calculated ion exchange isotherms, we show that it is possible to exchange Na+ with K+ and Rb+ in water, but that is not the case for systems in a vacuum. We also demonstrate that a solvation model should be used for the accurate representation of ion exchange in an LTA and that dispersion interactions should be introduced with care.

AB - Solvent-mediated interactions emerge from complex mechanisms that depend on the solute structure, its wetting properties, and the nature of the liquid. While numerous studies have focused on the first two influences, here, we compare the results from water and Lennard-Jones liquid in order to reveal to what extent solvent-mediated interactions are universal with respect to the nature of the liquid. Besides the influence of the liquid, the results were obtained with classical density functional theory and brute-force molecular dynamics simulations which allow us to contrast these two numerical techniques. PMID- 30292195 TI - Spin-polarized and thermospin-polarized transport properties of phthalocyanine dimer based molecular junction with different transition metal atoms. AB - Based on the first-principles density functional theory combined with the non equilibrium Green's function method, we have studied the spin-polarized and thermospin-polarized transport properties of phthalocyanine (Pc) dimer based molecular junction with different transition metal (TM = Mn, Fe, Co, Ni) atoms. Our results show that the spin-polarized and thermospin-polarized transport properties can be effectively tuned by changing the central TM atoms, and only the MnPc dimer system exhibits perfect spin/thermal-spin filtering and sizeable giant magnetoresistance (GMR)/thermal-GMR effects. Meantime, the MnPc dimer system reveals a low-bias negative differential resistance effect under the parallel magnetic configuration. These findings suggest that the MnPc dimer system has great potential in developing the high-performance multifunctional spintronic and spin caloritronic devices.

There are two alternative ways of enforcing this proposal for i -> a transitions in a system (M): (1) by using only eigenvalues obtained for the cationic species reached after the removal of an electron from orbital i (M +) or (2) by combining these quantities with the eigenvalue associated with orbital i from the neutral M system. We demonstrate that those eigenvalues derived from the equation-of-motion formalism in terms of the coupled cluster approach including single and double substitutions for ionization potentials and electron affinities show excellent performance in reproducing these electronic transition energies by either path, with mean absolute deviations (MADs) between 0.02 and 0.06 eV. Moreover, the Kohn Sham Density Functional Theory (KS-DFT) methods from the Quantum Theory Project (QTP) family provide nice results in terms of the second approach (MADs from 0.21 to 0.47 eV). However, DFT is not as successful as long as one takes into account only the eigenvalues of M +, although the respective excitation energies from QTP functionals are still reasonable (MADs between 0.55 and 0.74 eV). Ultimately, these relations can be used as a new consistency condition to develop KS-DFT approximations to the correlated orbital theory.

AB - Recently, we have introduced a new generation of effective core potentials (ECPs) designed for accurate correlated calculations but equally useful for a broad variety of approaches. The guiding principle has been the isospectrality of all electron and ECP Hamiltonians for a subset of valence many-body states using correlated, nearly-exact calculations. Here we present such ECPs for the 3d transition series Sc to Zn with Ne-core, i.e., with semi-core 3s and 3p electrons in the valence space. Besides genuine many-body accuracy, the operators are simple, being represented by a few gaussians per symmetry channel with resulting potentials that are bounded everywhere. The transferability is checked on selected molecular systems over a range of geometries. The ECPs show a high overall accuracy with valence spectral discrepancies typically ~0.01-0.02 eV or better. They also reproduce binding curves of hydride and oxide molecules typically within 0.02-0.03 eV deviations over the full non-dissociation range of interatomic distances.

AB - An artificial glycan cluster, in which 24 monosialotetrahexosylganglioside (GM1) glycans are transplanted to the interface of a metal-ligand complex, was recently proposed to investigate the interaction between GM1 glycan clusters and amyloidogenic proteins by NMR analysis. In this study, all-atom molecular dynamics simulations were performed to characterize the conformational properties of the artificial GM1 glycan cluster. We found that more than 65% of GM1 glycans are clustered by interchain hydrogen bonds. Interchain hydrogen bonds are mainly formed between Neu5Ac and Gal'. Pentamers were most frequently observed in the metal-ligand complex. GM1 glycans are tilted and hydrophobically interact with ligand moieties. The hydrophobic surface of the metal-ligand complex increases intrachain hydrogen bonds in each conformation of the GM1 glycans. The increase of intrachain hydrogen bonds stabilizes the local minimum conformations of the GM1 glycan in comparison with the monomeric one. Interchain hydrogen bonding between glycans and glycan-ligand hydrophobic interactions also contribute to this conformational stabilization. Our results provide the physicochemical properties of the new artificial GM1 glycan cluster under the thermal fluctuations for understanding its protein recognition and designing the drug material for amyloidogenic proteins. PMID- 30292199 TI - Machine learning enhanced global optimization by clustering local environments to enable bundled atomic energies. AB - We show how to speed up global optimization of molecular structures using machine learning methods. To represent the molecular structures, we introduce the auto bag feature vector that combines (i) a local feature vector for each atom, (ii) an unsupervised clustering of such feature vectors for many atoms across several structures, and (iii) a count for a given structure of how many times each cluster is represented. During subsequent global optimization searches, accumulated structure-energy relations of relaxed structural candidates are used to assign local energies to each atom using supervised learning. Specifically, the local energies follow from assigning energies to each cluster of local feature vectors and demanding the sum of local energies to amount to the structural energies in the least squares sense. The usefulness of the method is demonstrated in basin hopping searches for 19-atom structures described by single or double-well Lennard-Jones type potentials and for 24-atom carbon structures described by density functional theory. In all cases, utilizing the local energy information derived on-the-fly enhances the rate at which the global minimum energy structure is found.

AB - Exciton formation leads to J-bands in solid pentacene. Describing these exciton bands represents a challenge for both time-dependent (TD) density-functional theory (DFT) and for its semi-empirical analog, namely, for TD density-functional tight binding (DFTB) for three reasons: (i) solid pentacene and pentacene aggregates are bound only by van der Waals forces which are notoriously difficult to describe with DFT and DFTB, (ii) the proper description of the long-range coupling between molecules, needed to describe Davydov splitting, is not easy to include in TD-DFT with traditional functionals and in TD-DFTB, and (iii) mixing may occur between local and charge transfer excitons, which may, in turn, require special functionals. We assess how far TD-DFTB has progressed toward a correct description of this type of exciton by including both a dispersion correction for the ground state and a range-separated hybrid functional for the excited state and comparing the results against corresponding TD-CAM-B3LYP/CAM-B3LYP+D3 results. Analytic results for parallel-stacked ethylene are derived which go beyond Kasha's exciton model [M. Kasha, H. R. Rawls, and A. El-Bayoumi, Pure Appl. Chem. 11, 371 (1965)] in that we are able to make a clear distinction between charge transfer and energy transfer excitons. This is further confirmed when it is shown that range-separated hybrids have a markedly greater effect on charge-transfer excitons than on energy-transfer excitons in the case of parallel stacked pentacenes. TD-DFT calculations with the CAM-B3LYP functional and TD-lc DFT calculations lead to negligible excitonic corrections for the herringbone crystal structure, possibly because of an overcorrection of charge-transfer effects (CAM refers to Coulomb attenuated method). In this case, TD-DFT calculations with the B3LYP functional or TD-DFTB calculations parameterized to B3LYP give the best results for excitonic corrections for the herringbone crystal structure as judged from comparison with experimental spectra and with Bethe Salpeter equation calculations from the literature. PMID- 30292201 TI - On the phase diagram of Mackay icosahedra. AB - Using Monte Carlo and molecular dynamics simulations, we investigate the equilibrium phase behavior of a monodisperse system of Mackay icosahedra. We define the icosahedra as polyatomic molecules composed of a set of Lennard-Jones subparticles arranged on the surface of the Mackay icosahedron. The phase diagram contains a fluid phase, a crystalline phase, and a rotator phase. We find that the attractive icosahedral molecules behave similar to hard geometric icosahedra for which the densest lattice packing and the rotator crystal phase have been identified before. We show that both phases form under attractive interactions as well. When heating the system from the dense crystal packing, there is first a transition to the rotator crystal and then another to a fluid phase. PMID- 30292202 TI - Numerical investigation of effects of curvature and wettability of particles on heterogeneous condensation. AB - The incipient process of water vapor condensation around an insoluble nanoscale particle is studied by a molecular dynamics method, and the emphasis is placed on the effects of particle surface curvature and wettability. With a high initial saturation, two different linear nucleation stages are observed. At the first stage, clusters are formed by the water molecules adsorbed on the surface such that the nucleation rate is significantly affected by both water molecule flux toward the surface and adsorption probability. The former decreases with the surface curvature, and the latter is in proportion to the wettability. At the second stage, the nucleation rate is enhanced by the contribution of homogeneous clusters adsorbed to the surface and reduced by cluster merging because of the space limitation on small particles. As a result, the nucleation rate is basically not affected by the particle size. The average size of clusters keeps constant for a while, then starts to grow with a gradually increased growth rate. It is concluded that both curvature and wettability of the particle surface promote the cluster growing. PMID- 30292203 TI - Multiphoton photoelectron circular dichroism of limonene with independent polarization state control of the bound-bound and bound-continuum transitions. AB - Photoionization of randomly oriented chiral molecules with circularly polarized light leads to a strong forward/backward asymmetry in the photoelectron angular distribution. This chiroptical effect, referred to as Photoelectron Circular Dichroism (PECD), was shown to take place in all ionization regimes, from single photon to tunnel ionization. In the Resonance Enhanced Multiphoton Ionisation (REMPI) regime, where most of the table-top PECD experiments have been performed, understanding the role of the intermediate resonances is currently the subject of experimental and theoretical investigations. In an attempt to decouple the role of bound-bound and bound-continuum transitions in REMPI-PECD, we photoionized the (+)-limonene enantiomer using two-color laser fields in [1 + 1'] and [2 + 2'] ionization schemes, where the polarization state of each color can be controlled independently. We demonstrate that the main effect of the bound-bound transition is to break the sample isotropy by orientation-dependent photoexcitation, in agreement with recent theoretical predictions. We show that the angular distribution of PECD strongly depends on the anisotropy of photoexcitation to the intermediate state, which is different for circularly and linearly polarized laser pulses. On the contrary, the helicity of the pulse that drives the bound bound transition is shown to have a negligible effect on the PECD. PMID- 30292204 TI - Dissociation of GaN2+ and AlN2+ in APT: Analysis of experimental measurements. AB - The use of a tip-shaped sample for the atom probe tomography technique offers the unique opportunity to analyze the dynamics of molecular ions in strong DC fields. We investigate here the stability of AlN2+ and GaN2+ dications emitted from an Al0.25Ga0.75N sample in a joint theoretical and experimental study. Despite the strong chemical resemblance of these two molecules, we observe only stable AlN2+, while GaN2+ can only be observed as a transient species. We simulate the emission dynamics of these ions on field-perturbed potential energy surfaces obtained from quantum chemical calculations. We show that the dissociation is governed by two independent processes. For all bound states, a mechanical dissociation is induced by the distortion of the potential energy surface in the close vicinity of the emitting tip. In the specific case of GaN2+, the relatively small electric dipole of the dication in its ground 13Sigma- and excited 11Delta states induces a weak coupling with the electric field so that the mechanical dissociation into Ga+ + N+ lasts for sufficient time to be observed. By contrast, the AlN2+ mechanical dissociation leads to Al2+ + N which cannot be observed as a correlated event. For some deeply bound singlet excited states, the spin-orbit coupling with lower energy triplet states gives another chance of dissociation by system inter-system crossing with specific patterns observed experimentally in a correlated time of flight map.

AB - Spectra reflecting the formation of single-site double-core-hole pre-edge states involving the N 1s and C 1s core levels of acetonitrile have been recorded by means of high-resolution single-channel photoelectron spectroscopy using hard X ray excitation. The data are interpreted with the aid of ab initio quantum chemical calculations, which take into account the direct or conjugate nature of this type of electronic states. Furthermore, the photoelectron spectra of N 1s and C 1s singly core-ionized states have been measured. From these spectra, the chemical shift between the two C 1s-1 states is estimated. Finally, by utilizing C 1s single and double core-ionization potentials, initial and final state effects for the two inequivalent carbon atoms have been investigated. PMID- 30292206 TI - Accurate quantum molecular dynamics for multidimensional systems by the basis expansion leaping multi-configuration Gaussian (BEL MCG) method. AB - Quantum phenomena are quite often of critical importance in chemical reactions. Thus the development of quantum molecular dynamics approaches is required to study the role of quantum effects such as tunnelling in chemical processes. The basis expansion leaping multi-configuration Gaussian (BEL MCG) method has been developed to obtain time-propagated wave packets describing reactive molecular systems. Here we examine the applicability of BEL MCG to double well problems in several dimensions. We pay particular attention to what is required to yield highly accurate dynamics with respect to several key features of the BEL MCG propagation. The importance of using basis functions of a width appropriate to the nature of the potential energy surface in the region of configuration space where each basis function is located is highlighted, which has implications for virtually all quantum molecular dynamics methods utilising Gaussian basis functions. PMID- 30292207 TI - Polytetrahedral structure and glass-forming ability of simulated Ni-Zr alloys. AB - Binary Cu-Zr system is a representative bulk glassformer demonstrating high glass forming ability (GFA). From the first glance, the Ni-Zr system is the most natural object to expect the same behavior because nickel and copper are neighbors in the periodic table and have similar physicochemical properties. However, it is known that the Ni-Zr system has worse GFA than the Cu-Zr one. To understand the underlying physics, we investigate the Ni alpha Zr1-alpha system in whole concentration range alpha ? [0, 1]. Doing molecular dynamic simulations with a reliable embedded atom model potential, we show that the simulated Ni-Zr system also has relatively low GFA, which is comparable to that for an additive binary Lennard-Jones mixture without any chemical interaction. Icosahedral local ordering in Ni-Zr alloys is known to be less pronounced than that in the Cu-Zr ones; we see that as well. However, the icosahedron is not the only structural motif responsible for GFA. We find that the local structure of glassy Ni alpha Zr1-alpha alloys at 0.3 < alpha < 0.65 can be described in terms of Z11-Z16 Kasper polyhedra with high density of topological defects including icosahedra as a part of this family. Concentration of topologically perfect Kasper polyhedra appears to be several times smaller than that in Cu-Zr. This is the reason for relatively poor GFA of the Ni-Zr system. PMID- 30292208 TI - Fully anharmonic infrared cascade spectra of polycyclic aromatic hydrocarbons. AB - The infrared (IR) emission of polycyclic aromatic hydrocarbons (PAHs) permeates our universe; astronomers have detected the IR signatures of PAHs around many interstellar objects. The IR emission of interstellar PAHs differs from their emission as seen under conditions on Earth as they emit through a collisionless cascade down through their excited vibrational states from high internal energies. The difficulty in reproducing interstellar conditions in the laboratory results in a reliance on theoretical techniques. However, the size and complexity of PAHs require careful consideration when producing the theoretical spectra. In this work, we outline the theoretical methods necessary to lead to fully theoretical IR cascade spectra of PAHs including: an anharmonic second order vibrational perturbation theory treatment, the inclusion of Fermi resonances through polyads, and the calculation of anharmonic temperature band shifts and broadenings (including resonances) through a Wang-Landau approach. We also suggest a simplified scheme to calculate vibrational emission spectra that retain the essential characteristics of the full IR cascade treatment and can directly transform low temperature absorption spectra in IR cascade spectra. Additionally we show that past astronomical models were in error in assuming a 15 cm-1 correction was needed to account for anharmonic emission effects. PMID- 30292209 TI - Communication: Optically induced decoupling of the smectic-A and nematic order parameters at the AN phase transition in phototropic liquid crystals. AB - In the present work, by means of the photopyroelectric calorimetric investigations in liquid crystal/naphtopyran (NP) molecule mixtures, the effect of the photoisomerization of NP by UV light on the critical behavior of specific heat could be studied over the smectic-nematic phase transition. It is shown that the UV light irradiation of the sample can shift the critical exponent from a non universal value typical of the non-irradiated mixture to one close to that of the 3D-XY universality class, predicted for such a transition. This witnesses the optically triggered reduction of the coupling between the smectic and nematic order parameters responsible for the deviation from the XY-like behavior. A tentative explanation is provided based on the weakening of the order parameter coupling caused by the NP molecules entering the smectic layers following the UV light illumination.

PMID- 30292211 TI - Exponential parameterization of wave functions for quantum dynamics: Time dependent Hartree in second quantization. AB - We derive equations for describing the time evolution of variational wave functions in linear and exponential parameterization with a second-quantization (SQ) formulation. The SQ formalism covers time-dependent Hartree (TDH), while exact states and approximate vibrational configuration interaction wave functions are described using state-transfer operators. We present detailed expressions for efficient evaluation of TDH in linear (L-TDH) and exponential (X-TDH) parametrization and an efficient implementation supporting linear scaling with respect to the number of degrees of freedom M when the Hamiltonian operator contains a constant number of terms per mode independently of the size of the system. The computational cost of the X-TDH method is reduced significantly compared to the L-TDH method for systems with many operator terms per mode such as is typical for accurate molecular potential-energy surfaces. Numerical results for L-TDH and X-TDH are presented which confirm the theoretical reduction of the M scaling compared to standard first-quantization formulations. Calculations on Henon-Heiles potentials with more than 105 dimensions and polycyclic aromatic hydrocarbons with up to 264 modes have been performed. Thus, the SQ formulation and the X-TDH method pave the way for studying the time-resolved quantum dynamics of large molecules. PMID- 30292212 TI - Accurate electron affinity of Ti and fine structures of its anions. AB - The high-resolution photoelectron energy spectra of atomic titanium and its hydride anions were obtained on a slow-electron velocity-map imaging spectrometer equipped with a cold ion trap. The cold ion trap employed in the present measurement was found to be very helpful for reducing the interference from the titanium hydride anions. The electron affinity of Ti was determined to be 609.29(34) cm-1 or 75.54(4) meV. The accuracy was improved by a factor of 350 compared with the previous result. The fine structures of Ti- were clearly resolved: 70.0(12)(4F5/2), 165.2(15)(4F7/2), and 285.2(15) cm-1 (4F9/2) above its ground state 4F3/2. Moreover, the measured electron affinity and vibrational frequency of TiH can be reproduced well using the high level calculations. PMID- 30292213 TI - Encoding and selecting coarse-grain mapping operators with hierarchical graphs. AB - Coarse-grained (CG) molecular dynamics (MD) can simulate systems inaccessible to fine-grained (FG) MD simulations. A CG simulation decreases the degrees of freedom by mapping atoms from an FG representation into agglomerate CG particles. The FG to CG mapping is not unique. Research into systematic selection of these mappings is challenging due to their combinatorial growth with respect to the number of atoms in a molecule. Here we present a method of reducing the total count of mappings by imposing molecular topology and symmetry constraints. The count reduction is illustrated by considering all mappings for nearly 50 000 molecules. The resulting number of mapping operators is still large, so we introduce a novel hierarchical graphical approach which encodes multiple CG mapping operators. The encoding method is demonstrated for methanol and a 14-mer peptide. With the test cases, we show how the encoding can be used for automated selection of reasonable CG mapping operators. PMID- 30292214 TI - Charged nanorods at heterogeneously charged surfaces. AB - We study the spatial and orientational distribution of charged nanorods (rodlike counterions) as well as the effective interaction mediated by them between two plane-parallel surfaces that carry fixed (quenched) heterogeneous charge distributions. The nanorods are assumed to have an internal charge distribution, specified by a multivalent monopolar moment and a finite quadrupolar moment, and the quenched surface charge is assumed to be randomly distributed with equal mean and variance on the two surfaces. While equally charged surfaces are known to repel within the traditional mean-field theories, the presence of multivalent counterions has been shown to cause attractive interactions between uniformly charged surfaces due to the prevalence of strong electrostatic couplings that grow rapidly with the counterion valency. We show that the combined effects due to electrostatic correlations (caused by the coupling between the mean surface field and the multivalent, monopolar, charge valency of counterions) as well as the disorder-induced interactions (caused by the coupling between the surface disorder field and the quadrupolar moment of counterions) lead to much stronger attractive interactions between two randomly charged surfaces. The interaction profile turns out to be a nonmonotonic function of the intersurface separation, displaying an attractive minimum at relatively small separations, where the ensuing attraction can exceed the maximum strong-coupling attraction (produced by multivalent monopolar counterions between uniformly charged surfaces) by more than an order of magnitude. PMID- 30292215 TI - Semiclassical transition state theory based on fourth order vibrational perturbation theory: Model system studies beyond symmetric Eckart barrier. AB - The following one-dimensional model potential barriers are studied to compute the tunneling probabilities using semiclassical transition state theory (SCTST) based on fourth order vibrational perturbation theory (VPT4): (i) Morse barrier, (ii) asymmetric Eckart barrier, (iii) adjacent well barrier, and (iv) first order approximation to the symmetric Eckart barrier. The current investigation extends a previous study performed for the symmetric Eckart barrier. The performance of VPT4-SCTST is investigated for a broad range of energies, including the very deep tunneling regime (approximately 1% of the barrier height), and the results are compared to the exact quantum mechanical treatment, as well as to the popular second order vibrational perturbation theory (VPT2)-SCTST approach. While the VPT4-SCTST results are in excellent agreement with their quantum mechanical counterparts for a wide range of energies above and below the barrier, it is found for systems (ii) and (iv) that higher order terms (in n+12 ) in energy expansion are important for similarly excellent agreement in the deep tunneling regime. For the asymmetric Eckart barrier, the convergence properties of SCTST are analyzed in terms of its analytically known Siegert eigenvalues. A simple empirical modification of VPT2-SCTST advocated in the aforementioned previous work for the symmetric Eckart barrier is also tested here for the new model systems, and it is shown not to provide a uniformly systematic improvement. PMID- 30292216 TI - Effects of electron-phonon coupling on quantum interference in polyenes. AB - It has been well accepted that when quantum interference (QI) occurs in a single molecular junction comprised of a pi-conjugated molecule, the elastic pi-electron transmission is blocked, while the elastic sigma-electron transmission remains unchanged. When it comes to inelastic transport, in which passing electrons across the molecule trapped in between two metallic electrodes lose their energy through electron-phonon coupling, it is not necessarily obvious whether vibration affects the QI feature or not. In this paper, on the basis of a Huckel/tight binding model, we address the inelastic transport through linear and cyclic polyenes which are conditioned to show QI. The zeroth-order Green's function approximated by the negative inverse of the adjacency matrix of a molecular graph is used in conjunction with the lowest order expansion of the self-consistent Born approximation. Owing to the simplification of the model, it just finds the limited applicability for the pi-to-pi scattering. Only topological aspects of dephasing are included. In such a theoretical construct, the alternant nature of the pi-conjugated molecule is found helpful for classifying the dephasing patterns based on the parity of atomic sites. A rule is proposed, and it says that when both starred or both unstarred atoms are connected with the electrodes, QI always occurs, and atoms which belong to a different partite set from that of the atoms connected with the electrodes contribute to the inelastic pi-to-pi scattering. If QI occurs when a starred atom and an unstarred atom are connected with the electrodes, the contribution of the inelastic pi-to-pi scattering to the transport is expected to be unimportant.

AB - The physical properties of a liquid crystal-ionic liquid system were investigated. Low-frequency dielectric spectroscopy for 4-cyano-4'-pentylbiphenyl (5CB) doped with 1-butyl-3-methylimidazolium tetrafluoroborate (bmimBF 4) for the nematic and isotropic phase of host substances was performed. We obtained electrical conductivity values in the range from 298.2 K to 313.2 K and the conductivity anisotropy was confirmed. Further study of the relaxation process for bmim + allowed us to extract the relaxation frequencies and amplitudes from experimental data and confirm the temperature scaling; the thickness of the interfacial layers was estimated for the homogeneous and homeotropic alignments of the prepared composite. An attempt to unfold the ion contribution on the charge transport was made in order to better understand the electrode polarization process. In this work, the influence of the alignment layer and phase state on the interfacial layer formation in liquid crystal media will be explained better. PMID- 30292218 TI - Onset of natural selection in populations of autocatalytic heteropolymers. AB - Reduction of information entropy along with ever-increasing complexity is among the key signatures of life. Understanding the onset of such behavior in the early prebiotic world is essential for solving the problem of the origin of life. Here we study a general problem of heteropolymers capable of template-assisted ligation based on Watson-Crick-like hybridization. The system is driven off equilibrium by cyclic changes in the environment. We model the dynamics of 2 mers, i.e., sequential pairs of specific monomers within the heteropolymer population. While the possible number of them is Z 2 (where Z is the number of monomer types), we observe that most of the 2-mers get extinct, leaving no more than 2Z survivors. This leads to a dramatic reduction of the information entropy in the sequence space. Our numerical results are supported by a general mathematical analysis of the competition of growing polymers for constituent monomers. This natural-selection-like process ultimately results in a limited subset of polymer sequences. Importantly, the set of surviving sequences depends on initial concentrations of monomers and remains exponentially large (2 L down from Z L for length L) in each of realizations. Thus, an inhomogeneity in initial conditions allows for a massively parallel search of the sequence space for biologically functional polymers, such as ribozymes. We also propose potential experimental implementations of our model in the contexts of either biopolymers or artificial nano-structures.

AB - Experimental electron scattering cross sections for thiophene in the impact energy range from 1 to 300 eV have been measured with a magnetically confined electron transmission-beam apparatus. Random uncertainty limits have been estimated to be less than 5%, and systematic errors derived from acceptance angle limitations have also been identified and evaluated. Experimental values are compared with our previous low energy (1-15 eV) R-matrix and intermediate/high energy (15-300 eV) IAM-SCAR+I calculations finding reasonable agreement, within the combined uncertainty limits. Some of the low energy shape and core-excited resonances predicted by previous calculations are experimentally confirmed in this study. PMID- 30292220 TI - Collective modes of two-dimensional classical Coulomb fluids. AB - Molecular dynamics simulations have been performed to investigate in detail collective modes spectra of two-dimensional Coulomb fluids in a wide range of coupling. The obtained dispersion relations are compared with theoretical approaches based on quasi-crystalline approximation, also known as the quasi localized charge approximation, in the plasma-related context. An overall satisfactory agreement between theory and simulations is documented for the longitudinal mode at moderate coupling and in the long-wavelength domain at strong coupling. For the transverse mode, satisfactory agreement in the long wavelength domain is only reached at very strong coupling, when the cutoff wave number below which shear waves cannot propagate becomes small. The dependence of the cutoff wave-number for shear waves on the coupling parameter is obtained. PMID- 30292221 TI - Nascent O2 (a 1Deltag, v = 0, 1) rotational distributions from the photodissociation of jet-cooled O3 in the Hartley band. AB - We report rotational distributions for the O2 (a 1Deltag) fragment from the photodissociation of jet-cooled O3 at 248, 266, and 282 nm. The rotational distributions show a population alternation that favors the even states, as previously reported for a 300 K sample by Valentini et al. [J. Chem. Phys. 86, 6745 (1987)]. The alternation from the jet-cooled precursor is much stronger than that observed by Valentini et al. and in contrast to their observations does not depend strongly on the O2 (a 1Deltag) vibrational state or photolysis wavelength. The odd/even alternation diminishes substantially when the ozone beam temperature is increased from 60 to 200 K, confirming its dependence on parent internal energy. The magnitude of the even/odd alternation in product rotational states from the cold ozone sample, its temperature dependence, and other experimental and theoretical evidence reported since 1987 suggest that the alternation originates from a Lambda-doublet propensity and not from a mass independent curve crossing effect, as previously proposed. PMID- 30292222 TI - Favoritism of quantum dot inter-Coulombic decay over direct and multi-photon ionization by laser strength and focus. AB - We study the dynamics of a two-electron system undergoing resonant excitation and inter-Coulombic decay (ICD) in a pair of quantum dots. The influence of the focus of the exciting laser on the ICD process is investigated for a pi-pulse with a close look on competing processes, i.e., direct ionization and multi-photon excitations. We scan through the field strength up to six Rabi cycles to show that ICD is still verifiable after several population inversions. With novel analyses, we determine for the first time populations of the different continuum states and thus conclude on the importance of several multi-photon excitation channels. Finally, we look into the influence of complex absorbing potentials on the dynamics. PMID- 30292223 TI - Accurate and efficient numerical simulation of dielectrically anisotropic particles. AB - A variety of electrostatic phenomena, including the structure of electric double layers and the aggregation of charged colloids and proteins, are affected by nonuniform electric permittivity. These effects are frequently ignored in analytical and computational studies and particularly difficult to handle in situations where multiple dielectric contrasts are present, such as in colloids that are heterogeneous in permittivity. We present an extension to the Iterative Dielectric Solver developed by Barros and Luijten [Phys. Rev. Lett. 113, 017801 (2014)] that makes it possible to accurately compute the polarization of anisotropic particles with multiple dielectric contrasts. This efficient boundary element-method-based approach is applicable to geometries that are not amenable to other solvers, opening the possibility of studying collective phenomena of dielectrically anisotropic particles. We provide insight into the underlying physical reasons for this efficiency. PMID- 30292225 TI - The rotational spectrum and potential energy surface of the Ar-SiO complex. AB - The rotational spectra of five isotopic species of the Ar-SiO complex have been observed at high-spectral resolution between 8 and 18 GHz using chirped Fourier transform microwave spectroscopy and a discharge nozzle source; follow-up cavity measurements have extended these measurements to as high as 35 GHz. The spectrum of the normal species is dominated by an intense progression of a-type rotational transitions arising from increasing quanta in the Si-O stretch, in which lines up to v = 12 (~14 500 cm-1) were identified. A structural determination by isotopic substitution and a hyperfine analysis of the Ar-Si17O spectrum both suggest that the complex is a highly fluxional prolate symmetric rotor with a vibrationally averaged structure between T-shaped and collinear in which the oxygen atom lies closer to argon than the silicon atom, much like Ar-CO. To complement the experimental studies, a full dimensional potential and a series of effective vibrationally averaged, two-dimensional potential energy surfaces of Ar + SiO have been computed at the CCSD(T)-F12b/CBS level of theory. The equilibrium structure of Ar-SiO is predicted to be T-shaped with a well depth of 152 cm-1, but the linear geometry is also a minimum, and the potential energy surface has a long, flat channel between 140 and 180 degrees . Because the barrier between the two wells is calculated to be small (of order 5 cm-1) and well below the zero point energy, the vibrationally averaged wavefunction is delocalized over nearly 100 degrees of angular freedom. For this reason, Ar-SiO should exhibit large amplitude zero-point motion, in which the vibrationally excited states can be viewed as resonances with long lifetimes. Calculations of the rovibrational level pattern agree to within 2% with the transition frequencies of normal and isotopic ground state Ar-SiO, and the putative K a = +/-1 levels for Ar-28SiO, suggesting that the present theoretical treatment well reproduces the salient properties of the intramolecular potential.

Previous theoretical models have made strong inroads in the analysis of beta (B)-factors by linearly fitting protein B factors from experimental data. However, the blind prediction of B-factors for unknown proteins is an unsolved problem. This work integrates machine learning and advanced graph theory, namely, multiscale weighted colored graphs (MWCGs), to blindly predict B-factors of unknown proteins. MWCGs are local features that measure the intrinsic flexibility due to a protein structure. Global features that connect the B-factors of different proteins, e.g., the resolution of X-ray crystallography, are introduced to enable the cross-protein B-factor predictions. Several machine learning approaches, including ensemble methods and deep learning, are considered in the present work. The proposed method is validated with hundreds of thousands of experimental B-factors. Extensive numerical results indicate that the blind B-factor predictions obtained from the present method are more accurate than the least squares fittings using traditional methods.

AB - A chemical dynamics simulation was performed to model experiments [N. A. West et al., J. Chem. Phys. 145, 014308 (2016)] in which benzene molecules are vibrationally excited to 148.1 kcal/mol within a N2-benzene bath. A significant fraction of the benzene molecules are excited, resulting in heating of the bath, which is accurately represented by the simulation. The interesting finding from the simulations is the non-statistical collisional energy transfer from the vibrationally excited benzene C6H6 * molecules to the bath. The simulations find that at ~10-7 s and 1 atm pressure there are four different final temperatures for C6H6 * and the bath. N2 vibration is not excited and remains at the original bath temperature of 300 K. Rotation and translation degrees of freedom of both N2 and C6H6 in the bath are excited to a final temperature of ~340 K. Energy transfer from the excited C6H6 * molecules is more efficient to vibration of the C6H6 bath than its rotation and translation degrees of freedom, and the final vibrational temperature of the C6H6 bath is ~453 K, if the average energy of each C6H6 vibration mode is assumed to be RT. There is no vibrational equilibration between C6H6 * and the C6H6 bath molecules. When the simulations are terminated, the vibrational temperatures of the C6H6 * and C6H6 bath molecules are ~537 K and ~453 K, respectively. An important question is the time scale for complete energy equilibration of the C6H6 * and N2 and C6H6 bath system. At 1 atm and 300 K, the experimental V-T (vibration-translation) relaxation time for N2 is ~10-4 s. The simulation time was too short for equilibrium to be attained, and the time for complete equilibration of C6H6 * vibration with translation, rotation, and vibration of the bath was not determined. PMID- 30292227 TI - Accurate double excitations from ensemble density functional calculations. AB - The recent use of a new ensemble in density functional theory (DFT) to produce direct corrections to the Kohn-Sham transitions yields the elusive double excitations that are missed by time-dependent DFT (TDDFT) with the standard adiabatic approximation. But accuracies are lower than for single excitations, and formal arguments about TDDFT suggest that a correction kernel is needed. In principle, ensemble DFT with direct corrections at the exchange level must yield accurate doubles in the weakly correlated limit. We illustrate with exact calculations and analytic results on the Hubbard dimer. We also explain the error in formal arguments in TDDFT. PMID- 30292228 TI - pi - pi stacking vs. C-H/ pi interaction: Excimer formation and charge resonance stabilization in van der Waals clusters of 9,9'-dimethylfluorene. AB - Studies of exciton and hole stabilization in multichromophoric systems underpin our understanding of electron transfer and transport in materials and biomolecules. The simplest model systems are dimeric, and recently we compared the gas-phase spectroscopy and dynamics of van der Waals dimers of fluorene, 9 methylfluorene (MF), and 9,9'-dimethylfluorene (F1) to assess how sterically controlled facial encumbrance modulates the dynamics of excimer formation and charge resonance stabilization (CRS). Dimers of fluorene and MF show only excimer emission upon electronic excitation, and significant CRS as evidenced in a reduced ionization potential for the dimer relative the monomer. By contrast, the dimer of F1 shows no excimeric emission, rather structured emission from the locally excited state of a tilted (non pi-stacked) dimer, evidencing the importance of C-H/pi interactions and increased steric constraints that restrict a cofacial approach. In this work, we report our full results on van der Waals clusters of F1, using a combination of theory and experiments that include laser induced fluorescence, mass-selected two-color resonant two-photon ionization spectroscopy, and two-color appearance potential measurements. We use the latter to derive the binding energies of the F1 dimer in ground, excited, and cation radical states. Our results are compared with van der Waals and covalently linked clusters of fluorene to assess both the relative strength of pi-stacking and C H/pi interactions in polyaromatic assemblies and the role of pi-stacking in excimer formation and CRS. PMID- 30292229 TI - Adsorption and phase behavior of water-like fluid models with square-well attraction and site-site association in slit-like pores: Density functional approach. AB - The adsorption and phase behavior of two model fluids, both with square well inter-particle attraction and site-site associative interaction, in slit-like pores have been studied in the framework of a density functional theory. The mean field approach and the first-order mean spherical approximation have been applied to account for the attractive interactions. The chemical association effects are taken into account by using the first-order thermodynamic perturbation theory of Wertheim. A set of parameters for each fluid model has been chosen according to the work of [Clark et al., Mol. Phys. 104, 3561 (2006)], to describe successfully the vapor-liquid coexistence of water in the bulk phase. The influence of the slit-like pore width and of the strength of gas-solid interaction energy on the vapor-liquid coexistence envelope under confinement has been explored in detail. The theory and the results of the present work are valuable for further exploration of a wide set of models of associating fluids and of fluids with complex molecular architecture in different adsorbents, and to deal with activated carbon surfaces. PMID- 30292230 TI - Conformational change of a biomolecule studied by the weighted ensemble method: Use of the diffusion map method to extract reaction coordinates. AB - We simulate the nonequilibrium ensemble dynamics of a biomolecule using the weighted ensemble method, which was introduced in molecular dynamics simulations by Huber and Kim and further developed by Zuckerman and co-workers. As the order parameters to characterize its conformational change, we here use the coordinates derived from the diffusion map (DM) method, one of the manifold learning techniques. As a concrete example, we study the kinetic properties of a small peptide, chignolin in explicit water, and calculate the conformational change between the folded and misfolded states in a nonequilibrium way. We find that the transition time scales thus obtained are comparable to those using previously employed hydrogen-bond distances as the order parameters. Since the DM method only uses the 3D Cartesian coordinates of a peptide, this shows that the DM method can extract the important distance information of the peptide without relying on chemical intuition. The time scales are compared well with the previous results using different techniques, non-Markovian analysis and core-set milestoning for a single long trajectory. We also find that the most significant DM coordinate turns out to extract a dihedral angle of glycine, and the previously studied relaxation modes are well correlated with the most significant DM coordinates. PMID- 30292231 TI - A novel cerclage wiring technique in intertrochanteric femoral fractures treated by intramedullary nails in young adults. AB - BACKGROUND: Intertrochanteric femoral fractures (IFFs) in young adults, generally due to severe trauma, are increasingly presented. Different from IFFs in the geriatric population, these fractures in young adults are always comminuted and substantially displaced. Natural traction induced by musculature following IFFs determines closed reduction on a fracture table is extremely difficult. METHODS: To achieve anatomical reduction before intramedullary nail (IMN) fixation, we made an extended or a mini petrotrochantetic incision to facilitate temporary reduction using a pointed clamp. Subsequently, a curved and cannulated wire passer was employed to pass through a multistrand cable to surround displaced fragments and strengthen intertrochanteric fixation. Afterward, a standard procedure was conducted to nail the fracture. RESULTS: We used the surgical technique in 9 young patients with an age range of 28~ 48 years old. The fractures were categorized as AO/OTA 31-A2.2 (3 cases) and 31-A2.3 (6 cases). The injury-to-surgery interval was 2.5 days on average. Mean operation time was 55 min. All fractures achieved anatomical reduction and healed within 14 weeks postoperatively without cable breakage, implant irritation or deep infection. CONCLUSIONS: In conclusion, the surrounding technique with cerclage wire in IFFs in young adults is an effective surgical technique with easily achieved anatomical reduction to facilitate operative maneuvers and fracture healing.

AB - The original article [1] contains a major error carried across the captions of Tables 1, 2, and 3. In each table caption, the data were expressed as "mean +/- standard deviation (SD)"; unfortunately, the authors had mistakenly expressed the data as "mean +/- standard error (SE)" instead. As such, all mentions of "mean +/ standard error" in those table captions should of course state "mean +/- standard deviation". The authors are deeply sorry for these errors. PMID- 30292233 TI - Tumor-derived exosomes induce N2 polarization of neutrophils to promote gastric cancer cell migration. AB - BACKGROUND: Exosomes are extracellular vesicles that mediate cellular communication in health and diseases. Neutrophils could be polarized to a pro tumor phenotype by tumor. The function of tumor-derived exosomes in neutrophil regulation remains unclear. METHODS: We investigated the effects of gastric cancer cell-derived exosomes (GC-Ex) on the pro-tumor activation of neutrophils and elucidated the underlying mechanisms. RESULTS: GC-Ex prolonged neutrophil survival and induced expression of inflammatory factors in neutrophils. GC-Ex activated neutrophils, in turn, promoted gastric cancer cell migration. GC-Ex transported high mobility group box-1 (HMGB1) that activated NF-kappaB pathway through interaction with TLR4, resulting in an increased autophagic response in neutrophils. Blocking HMGB1/TLR4 interaction, NF-kappaB pathway, and autophagy reversed GC-Ex-induced neutrophil activation. Silencing HMGB1 in gastric cancer cells confirmed HMGB1 as a key factor for GC-Ex-mediated neutrophil activation. Furthermore, HMGB1 expression was upregulated in gastric cancer tissues. Increased HMGB1 expression was associated with poor prognosis in patients with gastric cancer. Finally, gastric cancer tissue-derived exosomes acted similarly as exosomes derived from gastric cancer cell lines in neutrophil activation. CONCLUSION: We demonstrate that gastric cancer cell-derived exosomes induce autophagy and pro-tumor activation of neutrophils via HMGB1/TLR4/NF-kappaB signaling, which provides new insights into mechanisms for neutrophil regulation in cancer and sheds lights on the multifaceted role of exosomes in reshaping tumor microenvironment. PMID- 30292236 TI - Experiences of aging in place in the United States: protocol for a systematic review and meta-ethnography of qualitative studies. AB - BACKGROUND: By 2035, older adults will outnumber children for the first time in the United States (US). In light of its aging population, the US has supported services focused on enabling older adults to continue living in their current homes, a model commonly described as "aging in place." The lived experience of aging in place is not well documented in existing systematic reviews. The aims of this systematic review are to synthesize and evaluate the existing qualitative evidence on experiences of aging in place in the US and identify knowledge gaps and directions for future studies. METHODS: Six electronic bibliographic databases (PubMed, PsycINFO, CINAHL, Web of Science, EMBASE, and Sociological Abstracts) will be searched. Studies presenting qualitative data on the experiences of older adults currently aging in place in the US will be included. Covidence software will be used to screen studies and extract data. The Joanna Briggs Institute checklist for qualitative research will be used to assess quality and risk of bias of included studies. We will use meta-ethnography, following the method described by Noblit and Hare, to synthesize and evaluate the results of the included studies. DISCUSSION: To the best of our knowledge, this is the first systematic review to integrate and synthesize the findings of qualitative studies of aging in place focusing on older adults in the US. The findings of this review will provide in-depth knowledge on lived experiences of aging in place and address important gaps in existing work.

PMID- 30292235 TI - CpG binding protein (CFP1) occupies open chromatin regions of active genes, including enhancers and non-CpG islands. AB - BACKGROUND: The mechanism by which protein complexes interact to regulate the deposition of post-translational modifications of histones remains poorly understood. This is particularly important at regulatory regions, such as CpG islands (CGIs), which are known to recruit Trithorax (TrxG) and Polycomb group proteins. The CxxC zinc finger protein 1 (CFP1, also known as CGBP) is a subunit of the TrxG SET1 protein complex, a major catalyst of trimethylation of H3K4 (H3K4me3). RESULTS: Here, we used ChIP followed by high-throughput sequencing (ChIP-seq) to analyse genomic occupancy of CFP1 in two human haematopoietic cell types. We demonstrate that CFP1 occupies CGIs associated with active transcription start sites (TSSs), and is mutually exclusive with H3K27 trimethylation (H3K27me3), a marker of polycomb repressive complex 2. Strikingly, rather than being restricted to active CGI TSSs, CFP1 also occupies a substantial fraction of active non-CGI TSSs and enhancers of transcribed genes. However, relative to other TrxG subunits, CFP1 was specialised to TSSs. Finally, we found enrichment of CpG-containing DNA motifs in CFP1 peaks at CGI promoters. CONCLUSIONS: We found that CFP1 is not solely recruited to CpG islands as it was originally defined, but also other regions including non-CpG island promoters and enhancers. PMID- 30292237 TI - Nanomedicine for drug delivery in South Africa: a protocol for systematic review. AB - BACKGROUND: The emergence of nanomedicine in the past decade has changed the landscape of disease diagnosis and treatment. Nanomedicine makes use of nanostructures for applications in different fields of medicine, including drug delivery, biosensors, neuro-electronic interfaces, in vivo imaging, and cell specific molecular interactions. Despite its relative infancy, nanomedicine has generated a significant body of research as evidenced by peer reviewed literature and several patents. This proposed systematic review will focus specifically on drug delivery systems in which nanoparticles are used to enhance the pharmacological and therapeutic properties of drugs. The strength of nanoparticulate drug delivery systems is their ability to alter the pharmacokinetics and bio-distribution of drugs. Globally, the discourse on nanomedicine is dominated by research being done in the developed countries of Europe and in the United States of America. Less attention has been given to the applications of nanomedicine in developing countries, particularly Africa. There is dearth of information on the applications of nanomedicine in terms of drug delivery with particular reference to which diseases are being targeted generally in Africa. The review will describe the specific diseases that are being targeted and the progress being made in South Africa, with a view to determining whether the applications of nanomedicine are being appropriated to address the context specific challenges in this country or if they mimic what is being done globally. METHODS: Keywords related to nanomedicine and drug delivery will be combined to build a search strategy for each of the following databases: PubMed, Cochrane Library (including Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews, Cochrane Methodology Register), Google Scholar, NHS Health Technology Assessment Database and Web of Science. We will also check reference lists of included studies for other eligible reports and search unpublished data. To ensure that the search is comprehensive, grey literature will be searched extensively. Literature to be included will have nanomedicine in drug delivery as the primary application and report on the specific diseases that are targeted in South Africa. Two authors will independently screen the search output, select studies and extract data; discrepancies will be resolved by consensus and discussion. When no consensus is reached, the third author will be consulted DISCUSSION: The systematic review will inform the government, policy-makers, investors, health professionals, scientists, and engineers about the applications of nanomedicine in drug delivery. In particular, it will identify the diseases targeted by the application of nanomedicine for drug delivery and the progress being made in South Africa as the disease burden of this country differs from that of developed countries where nanomedicine has been widely used for drug delivery.

PMID- 30292239 TI - Population-based studies of relationships between dietary acidity load, insulin resistance and incident diabetes in Danes. AB - BACKGROUND: It has been suggested that the acidity of the diet may be related to increased risk of type 2 diabetes. To investigate this hypothesis, we tested if the acidity of the diet, measured as the Potential Renal Acid Load (PRAL) score, was associated with incident diabetes and diabetes-related intermediary traits. METHODS: A total of 54,651 individuals from the Danish Diet, Cancer and Health (DCH) cohort were included in the prospective cox regression analyses of incident diabetes over a 15 years follow-up period. Moreover, 5724 Danish individuals with baseline data from the Inter99 cohort were included in the cross sectional, multivariate and logistic regression analyses of measures of insulin sensitivity, insulin release and glucose tolerance status derived from an oral glucose tolerance test (OGTT). RESULTS: In the DCH cohort a trend analysis showed that quintiles of PRAL score were, after multifactorial adjustment, associated with a higher incidence of diabetes (ptrend = 6 * 10- 7). HR for incident diabetes was 1.24 (1.14; 1.35) (p = 7 * 10- 7) between first and fifth PRAL score quintile. In Inter99 higher PRAL score associated with insulin resistance as estimated by lower BIGTT-Si (an OGTT-derived index of insulin sensitivity) (p = 4 * 10- 7) and Matsuda index of insulin sensitivity (p = 2 * 10- 5) as well as higher HOMA-IR (p = 0.001). No association was observed for measures of insulin release, but higher PRAL score was associated with lower OGTT-based disposition index. CONCLUSIONS: A high dietary acidity load is associated with a higher risk of diabetes among middle-aged Danes. Although adjustment for BMI attenuated the effect sizes the association remained significant. The increased risk of diabetes may be related to our finding that a high dietary acidity load associates with impaired insulin sensitivity. PMID- 30292240 TI - Friend retrovirus infection induces the development of memory-like natural killer cells. AB - Traditionally, NK cells belong to the innate immune system and eliminate virus infected cells through their germline-encoded receptors. However, NK cells were recently reported to possess memory-like functions that were predominantly provided by hepatic NK cells. Memory properties were mainly documented in contact hypersensitivity models or during cytomegalovirus infections. However, the precise role and the physiologic importance of memory-like NK cells during retroviral infections are still under investigation. Here, we show that Friend retrovirus (FV) infection of mice induced a population of phenotypically memory like NK cells at 28 days post infection. Upon secondary antigen encounter, these NK cells showed an increased production of the pro-inflammatory cytokines IFNgamma and TNFalpha as well as the death ligand FasL in comparison to naive NK cells. Furthermore, we found an augmented elimination of antigen-matched but not antigen-mismatched target cells by these memory-like NK cells. In adoptive cell transfer experiments, equal antiviral activities of splenic and hepatic memory like NK cells during the late phase of acute FV infection were found. Our results strongly imply the existence and antiviral activity of spleen and liver memory like NK cells in FV infection, which efficiently respond upon secondary exposure to retroviral antigens.

PMID- 30292242 TI - Shared decision making and antibiotic benefit-harm conversations: an observational study of consultations between general practitioners and patients with acute respiratory infections. AB - BACKGROUND: Little research has examined whether shared decision making (SDM) occurs in consultations for acute respiratory infections (ARIs), including what, and how, antibiotic benefits and harms are discussed. We aimed to analyse the extent and nature of SDM in consultations between GPs and patients with ARIs, and explore communication with and without the use of patient decision aids. METHODS: This was an observational study in Australian general practices, nested within a cluster randomised trial of decision aids (for acute otitis media [AOM], sore throat, acute bronchitis) designed for general practitioners (GPs) to use with patients, compared with usual care (no decision aids). Audio-recordings of consultations of a convenience sample of consenting patients seeing a GP for an ARI were independently analysed by two raters using the OPTION-12 (observing patient involvement in decision making) scale (maximum score of 100) and 5 items (about communicating evidence) from the Assessing Communication about Evidence and Patient Preferences (ACEPP) tool (maximum score of 5). Patients also self completed a questionnaire post-consultation that contained items from CollaboRATE 5 (perceptions of involvement in the decision-making process), a decisional conflict scale, and a decision self-efficacy scale. Descriptive statistics were calculated for each measure. RESULTS: Thirty-six consultations, involving 13 GPs, were recorded (20 for bronchitis, 10 sore throat, 6 AOM). The mean (SD) total OPTION-12 score was 29.4 (12.5; range 4-54), with item 12 (need to review decision) the highest (mean = 3) and item 10 (eliciting patients' preferred level of decision-making involvement) the lowest (mean = 0.1). The mean (SD) total ACEPP score was 2 (1.6), with the item about discussing benefits scoring highest. In consultations where a decision aid was used (15, 42%), compared to the 21 usual care consultations, mean observer-assessed SDM scores (OPTION-12, ACEPP scores) were higher and antibiotic harms mentioned in all (compared to only 1) consultations. Patients generally reported high decision involvement and self efficacy, and low decisional conflict. CONCLUSIONS: The extent of observer assessed SDM between GPs and patients with ARIs was generally low. Balanced discussion of antibiotic benefits and harms occurred more often when decision aids were used. PMID- 30292244 TI - Sight and Perspective. PMID- 30292243 TI - Massive hemothorax due to two bleeding sources with minor injury mechanism: a case report. AB - BACKGROUND: Massive hemothorax resulting from a minor injury mechanism is considered to be rare particularly when the diaphragm is injured. We report a case of massive hemothorax with bleeding from the intercostal artery and diaphragmatic damage caused by minor blunt trauma. CASE PRESENTATION: An 83-year old Japanese man was transported to our hospital 3 hours after falling out of bed. Computed tomography revealed hemothorax and multiple rib fractures. He underwent fluid resuscitation and a tube thoracostomy, but he became hemodynamically unstable. Contrast-enhanced computed tomography revealed worsening hemothorax with contrast extravasation 4 hours after arrival at the hospital. Emergency angiography indicated hemorrhage in the area supplied by the tenth intercostal artery. Transcatheter arterial embolization stabilized his vital signs for a short period. However, further hemodynamic stabilization required a thoracotomy, which revealed diaphragmatic trauma, which was removed and sutured before fixing his fractured ribs. His postoperative course was uneventful, and he was transferred to another hospital for rehabilitation without complications on hospital day 29. CONCLUSIONS: Minor mechanisms of blunt trauma can cause rib fractures and massive hemothorax. Traumatic diaphragm injury should be considered a differential diagnosis if hemodynamic instability persists after transcatheter arterial embolization in patients with lower level rib fractures.

AB - Background: The aim of this methodological study was to assess the reliability and validity of the Sexual Quality of Life - Male (SQoL-M) questionnaire translated and adapted to measure the sexual quality of life of men in Turkey and Northern Cyprus. Methods: To assess the reliability and validity of the Turkish version of the SQoL-M questionnaire, in January and February 2017 we formed a sample of 128 men from Ankara, Turkey, and Girne, Northern Cyprus, to complete the questionnaire. Two weeks later, 65 of these men completed the questionnaire during a retest. Factor analysis was conducted to evaluate the questionnaire's factor structure, internal consistency and test-retest reliability analyses were used to assess reliability and Pearson's correlation coefficient was used to measure criterion-related validity. Results: Cronbach's alpha for the Turkish version of the SQoL-M questionnaire was 0.91, with corrected item-total score correlations ranging from 0.432 to 0.819. The test-retest correlation, calculated to compare scale scores of both groups of participants, was 0.83 (P<0.001). We also observed a statistically significant relationship between the Turkish version of the SQoL-M questionnaire and the Arizona Sexual Experience scale. Conclusions: The Turkish version of the SQoL-M questionnaire is a valid, reliable instrument for evaluating the sexual quality of life of men in Turkey and Northern Cyprus.

PMID- 30292252 TI - Preoperative evaluation of pelvine lymph node metastasis in high risk prostate cancer with intravoxel incoherent motion (IVIM) MRI. AB - OBJECTIVES: To evaluate benign and malignant pelvine lymph nodes in prostate cancer patients with biexponential intravoxel incoherent motion (IVIM) MRI of the prostate prior to radical prostatectomy. METHODS: The ethics committee approved this retrospective study with waiver of informed consent. From February 2012 to November 2013 43 patients with histopathologically proven prostatic cancer were included. All patients were examined applying a standardized MRI protocol including IVIM diffusion weighted imaging with multiple b-values ranging from 0 to 950 s/mm2. MR imaging was performed one day prior to radical prostatectomy. Thereafter, extended lymph node resection was performed. For each MRI all visible lymph nodes were registered and calculated as individual regions of interest. These findings were correlated with postoperative pathology. The apparent diffusion coefficient ADC, the diffusion coefficient D and the perfusion fraction f were calculated from IVIM DWI using a biexponential fit. RESULTS: A total of 120 lymph nodes were detected on MRI. 95 of these were determined as benign and 25 as malignant. The average ADC was significantly lower in malignant compared to benign lymph nodes (0.88 * 10-3 vs 1.67 * 10-3 mm2/s, p < 0.001). Likewise, the average diffusion coefficient D was significantly lower in lymph node metastasis (0.54 * 10-3 vs 1.10 * 10-3 mm2/s, p < .001). The signal rate due to perfusion was significantly higher in malignant compared to benign nodes (33.4% vs. 27.1%, p = 0.02). CONCLUSIONS: Applying biexponential IVIM MRI demonstrates significant differences in diffusion parameters ADC and D, as well as in the perfusion fraction f for benign and malignant lymph nodes. Therefore, IVIM might help to further improve the preoperative assessment of lymph nodes in MRI. PMID- 30292253 TI - The evolution of magnetic resonance enterography in the assessment of motility disorders in children. AB - Gastrointestinal symptoms including constipation, diarrhoea, pain and bloating represent some of the most common clinical problems for patients. These symptoms can often be managed with cheap, widely available medication or will spontaneously resolve. However, for many patients, chronic GI symptoms persist and frequently come to dominate their lives. At one end of the spectrum there is Inflammatory Bowel Disease (IBD) with a clearly defined but expensive treatment pathway. Contrasting with this is Irritable Bowel Syndrome (IBS), likely a collection of pathologies, has a poorly standardised pathway with unsatisfactory clinical outcomes. Managing GI symptoms in adult populations is a challenge. The clinical burden of gastrointestinal disease is also prevalent in paediatric populations and perhaps even harder to treat. In this review we explore some of the recent advances in magnetic resonance imaging (MRI) to study the gastrointestinal tract. Complex in both its anatomical structure and its physiology we are likely missing key physiological markers of disease through relying on symptomatic descriptors of gut function. Using MRI we might be able to characterise previously opaque processes, such as non-propulsive contractility, that could lead to changes in how we understand even common symptoms like constipation. This review explores recent advances in the field in adult populations and examines how this safe, objective and increasingly available modality might be applied to paediatric populations. PMID- 30292254 TI - Breast MRI for prediction of lymphovascular invasion in breast cancer patients with clinically negative axillary lymph nodes. AB - OBJECTIVE: To retrospectively assess magnetic resonance imaging (MRI) findings that can predict lymphovascular invasion (LVI) in invasive breast cancer patients who were diagnosed with clinically negative axillary lymph nodes (LNs) preoperatively. METHODS: This study included 140 lesions of 140 patients who underwent preoperative breast MRI and breast surgery, with omission of axillary LN dissection. Clinical characteristics and MRI findings were evaluated. The T2 signal intensity (SI) ratio (mean T2 SI of the tumor/mean T2 SI of the muscle), tumor apparent diffusion coefficient (ADC) value, peritumoral ADC value, peritumor-tumor ADC ratio (peritumoral maximum ADC value/tumor mean ADC value), and ADC value of the contralateral breast parenchyma were retrospectively assessed. Statistical analyses were performed to identify significant factors for predicting LVI. Inter-observer variability was calculated. RESULTS: The tumor ADC value (all ages: p = 0.005; age <= 55: p < 0.001), peritumoral ADC value (age <= 55: p = 0.04), and peritumor-tumor ADC ratio (all ages: p < 0.001; age <= 55: p < 0.001) were significantly associated with LVI on univariate analysis. Multivariate logistic regression analysis revealed significant differences in the pathological size of the invasive component and the tumor ADC value for predicting LVI (odds ratio [OR]: 3.43; 95% confidence interval [CI]: 1.41-8.32; p = 0.007; OR: 16.0; 95% CI: 1.89-136; p = 0.01, respectively). Inter-observer agreement was substantial for the tumor ADC value (intraclass correlation coefficient [ICC] = 0.77; 95% CI: 0.70-0.83) and the ADC value of the contralateral breast parenchyma (ICC = 0.68; 95% CI: 0.59-0.76). There was moderate agreement for the peritumoral ADC value (ICC = 0.53; 95% CI: 0.40-0.64) and the peritumor-tumor ADC ratio (ICC = 0.49; 95% CI: 0.35-0.61) and fair agreement for the T2 SI ratio (ICC = 0.30; 95% CI: 0.15-0.45). CONCLUSION: We found that the tumor ADC value, peritumoral ADC value, and peritumor-tumor ADC ratio were predictive MRI findings for LVI in patients aged <=55. The tumor ADC value was the most significant predictor for LVI; moreover, inter-observer agreement for the tumor ADC value was substantial between two blinded observers with differences in interpretation experience.

AB - PURPOSE: A positive circumferential resection margin (CRM) is regarded as a poor prognostic indicator in oesophageal cancer (OC) but its prediction can be challenging. MRI is used to predict a threatened CRM in rectal cancer but is not commonly performed in OC unlike PET/CT, which is now routinely used. Therefore, this study assessed the additional predictive value of PET-defined tumour variables compared with EUS and CT T-stage. The prognostic significance of CRM status was also assessed. MATERIALS AND METHODS: This retrospective study included 117 consecutive patients [median age 64.0 (range 24-78), 102 males, 110 adenocarcinomas, 6 squamous cell carcinoma (SCC), 1 neuro-endocrine] treated between 1st March 2012 and 31st July 2015. A binary logistic regression model tested 5 staging variables; EUS T-stage (<=T2 vs >= T3), CT T-stage (<=T2 vs >= T3), PET metabolic tumour length (MTL), PET metabolic tumour width (MTW) and the maximum standardised uptake value (SUVmax). RESULTS: The CRM was positive in 43.6%. Sixty-seven (57.3%) patients received neo-adjuvant chemotherapy (NACT), 31 patients (26.5%) underwent surgery alone and 19 patients (16.2%) had neo-adjuvant chemo-radiotherapy (NACRT). Median overall survival (OS) was 36.0 months (95% confidence interval (CI) 24.1-47.9) and the 2-year OS was 55.4%. A binary logistic regression model showed EUS >= T3 tumours were independently and significantly more likely to have a positive CRM than EUS <= T2 tumours (HR 5.188, 95% CI 1.265-21.273, p = 0.022). CT T-stage, PET MTL, PET MTW and SUVmax were not significantly associated with CRM status (p = 0.783, 0.852, 0.605 and 0.413, respectively). There was a significant difference in OS between CRM positive and negative groups (X2 4.920, df 1, p = 0.027). CONCLUSION: Advanced EUS T-stage is associated with a positive CRM, but PET-defined tumour variables are unlikely to provide additional predictive information. This study demonstrates the continued benefit of EUS as part of a multi-modality OC staging pathway.

AB - OBJECTIVES: To compare high b value (2000 s/mm2) reduced field-of-view (rFOV) diffusion-weighted imaging (DWI) with a conventional DWI sequence in terms of image quality, as well as diagnostic performance concerning prostate cancer (PCa) detection and tumor staging at 3 T. METHODS: Sixty-one patients underwent rFOV DWI and conventional DWI due to clinical suspicious of PCa were retrospectively recruited. Imaging qualities were evaluated qualitatively and quantitatively by two blinded radiologists. Thirty-two subjects with detailed pathology reports were further analyzed for diagnostic efficacy using the Prostate Imaging Reporting and Data System (PI-RADS) version 2. The PCa detection rate, sensitivity, specificity, and PI-RADS staging changes were compared between the DWI sequences. RESULTS: Qualitative evaluation regarding image quality was significantly better in rFOV DWI than in the conventional DWI (all P < 0.05). ADC contrast with rFOV DWI was rated significantly higher than the conventional DWI in both peripheral zone (PZ) and transition zone (TZ) (P = 0.001 for PZ, and P = 0.003 for TZ). Regarding diagnostic efficacy, rFOV DWI yielded higher tumor detection, sensitivity and the area under the curve (AUC) than the conventional DWI (all P < 0.05), except the AUC in the PZ for one reader (P = 0.262). Conventional DWI achieved slightly higher specificity for the PZ and TZ but with no significant difference except for one reader in the PZ (P = 0.009). CONCLUSION: The rFOV DWI could offer improved image quality and yielded better diagnostic performance in terms of higher tumor detection rate and relatively precise staging for PCa compared to the conventional sequence. PMID- 30292257 TI - Recurrent renal cell carcinoma following nephrectomy and ablation therapy: Radiology perspective. AB - Renal cell carcinoma (RCC) is the most common renal malignancy, accounting for approximately 2% of adult malignancies and 4% of new cancer cases in the United States every year. Imaging guided ablative therapy, including radiofrequency (RF) ablation, cryotherapy and microwave has gained popularity over the last decade in treatment of small tumors. Antiangiogenic therapy has set itself to be the standard of care for many patients with metastasis these days. With hope for more research, survival rates of metastatic RCC may increase from a current 2-year survival rate of approximately 20%. Variation in imaging surveillance protocol in terms of frequency, modality, and duration is noted among guidelines developed by several organizations. In this review article, we will discuss follow-up imaging protocols, patterns of RCC recurrence following different modalities of treatment, imaging appearance, as well as usual and unusual sites of metastatic disease. PMID- 30292258 TI - A comparison of full-field digital mammograms versus 2D synthesized mammograms for detection of microcalcifications on screening. AB - OBJECTIVES: To compare the observer agreement of microcalcification detection on synthetic 2D images to full field digital mammography (FFDM) at screening and determine if calcifications can be detected to the same degree and given the same BI-RADS assessment. MATERIAL AND METHODS: Two-experienced radiologists retrospectively reviewed synthetic 2D images and FFDM, in separate sessions, to detect microcalcifications and provide a BIRADS assessment. A third experienced breast radiologist reviewed the cases that were disagreed upon and gave a final assessment. Between March 2016-December 2016, 414 women obtained a screening mammogram with tomosynthesis and acquisition of FFDM. 71 cases had combined FFDM and tomosynthesis images, calcifications visible on FFDM or no calcifications present, which comprised the study group. Synthetic 2D images were constructed from the DBT images. During session 1, all synthetic 2D images for the 71 cases were reviewed. During session 2, all the FFDM images for the 71 cases were reviewed. Tomosynthesis images were not reviewed. The agreement of detection of calcifications and BIRADS assessment between radiologists for FFDM and synthetic 2D images were assessed using Cohen's kappa test. Fisher's exact test was used to detect the differences in calcification identification among various breast densities on FFDM and synthetic 2D images. RESULTS: For the detection of calcifications between synthetic 2D images and FFDM, there was moderate to substantial agreement (p-values < 0.0001) for the two radiologist. For the BIRADS assessments, the agreement between synthetic 2D imaging and FFDM was moderate (p values < 0.0001). The inter-reader agreement for detection of calcifications was fair for using synthetic 2D and moderate for using FFDM (p-value < 0.0001). The final inter-reader agreement between FFDM and synthetic 2D images for the detection of calcifications was moderate (p-values < 0.0001) with the addition of the third reader. For the final BI-RADS assessment, there was moderate agreement between synthetic 2D imaging and FFDM (p-value < 0.0001). The two readers did not demonstrate a significant difference in the detection of microcalcifications for those who were dense or non-dense (p-value range 0.076-0.302). CONCLUSION: Radiologist interpreting synthetic 2D imaging and FFDM have similar frequency for detection of calcifications and BIRADS assessment. A synthetic 2D mammogram may be a sufficient replacement for FFDM at screening. PMID- 30292259 TI - A prospective clinical study using a dynamic contrast-enhanced CT-protocol for detection of colorectal liver metastases. AB - OBJECTIVE: To evaluate a dynamic contrast-enhanced CT-protocol and compare this method with standard of care monophasic portovenous CT for detection of colorectal liver metastases. MATERIALS AND METHODS: A dynamic contrast-enhanced CT protocol was developed to detect liver metastasis in patients suffering from colorectal cancer, in clinical practice. The study was approved by the Hospital Ethics Committee. Written informed consent was obtained from all patients. 135 patients were included in this prospective study. All patients were naive to treatment. A dynamic contrast-enhanced CT was performed, followed by routine monophasic portovenous CT of thorax-abdomen-pelvis. 42 of these patients presented with liver metastasis. The number and lesion conspicuity of detected liver metastasis on dynamic contrast-enhanced CT using perfusion maps, was compared to monophasic CT. RESULTS: 135 patients were included, of which 42 presented with metastases to the liver. Dynamic contrast-enhanced CT outperformed portovenous CT for detection as well as conspicuity of colorectal liver metastasis, at a relatively low dose increment. Wilcoxon Signed Rank test had a p value of 0.016 and <0.001 respectively for detection and conspicuity of colorectal liver metastasis. CONCLUSION: Dynamic contrast-enhanced CT increases the detection of colorectal liver metastasis, especially for lesions smaller than 15 mm, when compared to monophasic portovenous CT. Dynamic contrast-enhanced CT also has the added advantage of improved lesion conspicuity, which can positively influence reader confidence and clinical workflow. PMID- 30292260 TI - Textural differences between renal cell carcinoma subtypes: Machine learning based quantitative computed tomography texture analysis with independent external validation. AB - OBJECTIVE: To develop externally validated, reproducible, and generalizable models for distinguishing three major subtypes of renal cell carcinomas (RCCs) using machine learning-based quantitative computed tomography (CT) texture analysis (qCT-TA). MATERIALS AND METHODS: Sixty-eight RCCs were included in this retrospective study for model development and internal validation. Another 26 RCCs were included from public databases (The Cancer Genome Atlas-TCGA) for independent external validation. Following image preparation steps (reconstruction, resampling, normalization, and discretization), 275 texture features were extracted from unenhanced and corticomedullary phase CT images. Feature selection was firstly done with reproducibility analysis by three radiologists, and; then, with a wrapper-based classifier-specific algorithm. A nested cross-validation was performed for feature selection and model optimization. Base classifiers were the artificial neural network (ANN) and support vector machine (SVM). Base classifiers were also combined with three additional algorithms to improve generalizability performance. Classifications were done with the following groups: (i), non-clear cell RCC (non-cc-RCC) versus clear cell RCC (cc-RCC) and (ii), cc-RCC versus papillary cell RCC (pc-RCC) versus chromophobe cell RCC (chc-RCC). Main performance metric for comparisons was the Matthews correlation coefficient (MCC). RESULTS: Number of the reproducible features is smaller for the unenhanced images (93 out of 275) compared to the corticomedullary phase images (232 out of 275). Overall performance metrics of the machine learning-based qCT-TA derived from corticomedullary phase images were better than those of unenhanced images. Using corticomedullary phase images, ANN with adaptive boosting algorithm performed best for discrimination of non-cc-RCCs from cc-RCCs (MCC = 0.728) with an external validation accuracy, sensitivity, and specificity of 84.6%, 69.2%, and 100%, respectively. On the other hand, the performance of the machine learning based qCT-TA is rather poor for distinguishing three major subtypes. The SVM with bagging algorithm performed best for discrimination of pc-RCC from other RCC subtypes (MCC = 0.804) with an external validation accuracy, sensitivity, and specificity of 69.2%, 71.4%, and 100%, respectively. CONCLUSIONS: Machine learning-based qCT-TA can distinguish non-cc-RCCs from cc-RCCs with a satisfying performance. On the other hand, the performance of the method for distinguishing three major subtypes is rather poor. Corticomedullary phase CT images provide much more valuable texture parameters than unenhanced images. PMID- 30292261 TI - Staging/restaging performance of F18-fluorodeoxyglucose positron emission tomography/magnetic resonance imaging in breast cancer: A review and meta analysis. AB - PURPOSE: This systematic review and meta-analysis was performed to assess the staging/restaging performance of F18-fluorodeoxyglucose (FDG) positron emission tomography (PET)/magnetic resonance imaging (MRI) in breast cancer. METHODS: A comprehensive search was performed in PubMed databases for studies reporting the staging performance of F18-FDG PET/MRI in breast cancer from the inception of these databases to January 29, 2018. Eight studies were included in this systematic review and meta-analysis. Pooled estimates of patient- and lesion based sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR) of F18-FDG PET/MRI were calculated alongside 95% confidence intervals (CIs). A summary receiver operating characteristic curve (SROC) was plotted and the area under the SROC curve (AUC) was determined alongside the Q* index. RESULTS: The patient-based overall pooled sensitivity, specificity, PLR, NLR, DOR, and AUC of F18-FDG PET/MRI for staging in breast cancer were 0.98 (95% CI, 0.95-0.99), 0.87 (95% CI, 0.76-0.95), 4.59 (95% CI, 1.91-11.05), 0.03 (95% CI, 0.01-0.09), 203.07 (95% CI, 50.33-819.38), and 0.99, respectively. The lesion-based overall pooled sensitivity, specificity, PLR, NLR, DOR, and AUC of F18-FDG PET/MRI for staging in breast cancer were 0.91 (95% CI, 0.88-0.94), 0.95 (95% CI, 0.92-0.97), 11.28 (95% CI, 4.25-29.96), 0.07 (95% CI, 0.02-0.22), 286.46 (95% CI, 64.15-1279.17), and 0.99, respectively. The overall diagnostic accuracies (Q* index) of the staging performance of F18-FDG PET/MRI in breast cancer were 0.96 (patient-based analysis) and 0.95 (lesion based analysis). CONCLUSION: F18-FDG PET/MRI has excellent diagnostic staging/restaging performance in patients with breast cancer, and thus should be considered for staging of patients with breast cancer. PMID- 30292262 TI - Sub-solid nodule detectability in seven observers of seventy-nine clinical cases: comparison between ultra-low-dose chest digital tomosynthesis with iterative reconstruction and chest radiography by receiver-operating characteristics analysis. AB - PURPOSE: To compare sub-solid nodules detectability (SSND) between ultra-low-dose chest digital tomosynthesis (ULD-CDT) with/without iterative reconstruction (IR) and chest radiography (CR) by using low-dose computed tomography (LDCT) as the standard of reference (SOR). MATERIALS AND METHODS: Institutional Review Board approved this study and written informed consent was obtained. In a single visit, 79 subjects underwent ULD-CDT at 120 kV and 10 mA, CR and LDCT (effective dose: 0.171, 0.117 and 3.52 mSv, respectively). Sixty-three coronal images were reconstructed using CDT with/without IR. SOR as to SSN presence was determined based on LDCT images. Seven radiologists recorded SSN presence and locations by continuously-distributed rating. Receiver-operating characteristic (ROC) analysis was used to compare SSND of ULD-CDT with/without IR and CR, in total and subgroups classified by nodular longest diameter (LD) (> or < 9 mm) and mean CT attenuation value (CTAV) (> or < -600 Hounsfield of Unit (HU)). Detection sensitivity (DS) was compared among 4 groups classified by combination of the identical thresholds: nodular LD (9 mm) and mean CTAV (-600 HU) in each of ULD CDT with/without IR and CR with Friedman and Wilcoxon signed rank test. RESULTS: SSND for total 105 SSNs as well as larger SSNs with nodular LD of 9 mm or more at ULD-CDT with IR was higher than either that at ULD-CDT without IR or CR, as the areas under the ROC curve were 0.66 +/- 0.02, 0.59 +/- 0.01 and 0.52 +/- 0.01, respectively (p < 0.05). DS at ULD-CDT with IR was 69.5 +/- 10.8% in groups with larger (LD > 9 mm) and more-attenuated (>-600 HU) SSNs, and higher than in the other 3 groups (p < 0.05). CONCLUSION: ULD-CDT with IR demonstrated better SSND than that without IR or CR, with increased DS for larger and more-attenuated SSNs compared with the remaining ones. PMID- 30292264 TI - Children centered care: Minimizing the need for anesthesia with a multi-faceted concept for MRI in children aged 4-6. AB - PURPOSE: To evaluate the need for general anesthesia (GA) in MRI in children aged 4-6 years, using a multi-faceted concept, Children Centered Care (CCC), compared to a standard setup. MATERIALS AND METHODS: In this prospective study of 81 children, we developed and tested a multi-faceted concept, CCC, for MRI in children aged 4-6 without GA, comparing it to a standard setup. The CCC included: 1) an interactive app, 2) a trained pediatric team, 3) a children's lounge with a toy-scanner, and 4) a child-friendly multimedia environment in the MRI room. Patients were included from February-September 2016 and 2017. The use of GA was evaluated, image quality was assessed and a cost-benefit analysis was done. RESULTS: We included 40 children in the control group and 41 in the CCC group. Mean age was 5.8 years and 48 (59%) were males. Neuro and orthopedic imaging accounted for 58 (72%) and 22 (27%), respectively. With the CCC setup 39/41 (95%) completed a diagnostic MRI without GA compared to 17/40 (43%) in the control group (p < 0.001). Image quality was not different between the groups (p = 0.37). The setup proved cost-effective with a payback time of two years in a Danish setting with 250 eligible patients per year. CONCLUSION: With the multi-faceted concept CCC, the use of GA for MRI in children aged 4-6 was markedly reduced to 5%, image quality was maintained and the setup was cost-effective. PMID- 30292263 TI - CT-response patterns and the role of CT-textural features in inoperable abdominal/retroperitoneal soft tissue sarcomas treated with trabectedin. AB - PURPOSE: To evaluate CT patterns and textural features of soft tissue sarcomas following trabectedin therapy as well as their suitability for predicting therapeutic response. MATERIAL AND METHODS: A total of 31 patients (18 female, 13 male; mean age, 58.0years; range, 38-79years) with sarcoma under trabectedin as a third-line therapy between October 2008 and July 2017 underwent baseline and follow-up contrast-enhanced CT. Response evaluation was based on modifiedCHOI criteria and RECIST1.1, classified as partial response(PR), stable disease(SD), progressive disease(PD). For CT-texture analysis (CTTA), mean, entropy and uniformity of intensity/skewness/entropy of co-occurrence matrix (COM) and contrast of neighboring-grey-level-dependence-matrix (NGLDM) were calculated. RESULTS: Following CHOI-criteria, 9 patients achieved PR, 10 SD and 12 PD. RECIST1.1. classified patients into 5 PR, 15 SD and 11 PD. A frequent (n = 6/31; 19.3%) pattern of response was tumor liquefaction. In responders differences in entropy of entropy-NGLDM(p = 0.028) and uniformity-NGLDM(p = 0.021), in non responders entropy of average(p = 0.039), deviation(p = 0.04) and uniformity of deviation(p = 0.013) occured between baseline and follow-up. Mean intensity and average were higher when liquefication occured(p = 0.03; p = 0.02), whereas mean deviation was lower(p = 0.02) at baseline compared to other response patterns. Differences in mean(p = 0.023), entropy(p = 0.049) and uniformity(p = 0.023) of entropy-NGLDM were found between responders and non-responders at follow-up. For the mean of heterogeneity a cut-off value was calculated for prediction of response in baseline CTTA (0.12; sensitivity 89%; specificity 77%). CONCLUSION: A frequent pattern of response to trabectedin was tumor liquefication being responsible for pseudoprogression, therefore modifiedCHOI should be preferred. Single CT-textural features can be used complementarily for prediction and monitoring response to trabectedin. PMID- 30292265 TI - Breast cancer staging: Combined digital breast tomosynthesis and automated breast ultrasound versus magnetic resonance imaging. AB - PURPOSE: To investigate whether combined Digital breast tomosynthesis and Automated breast volume scanner (DBT-ABVS) are comparable to Magnetic resonance imaging (MRI) in staging breast cancer. METHODS: We retrospectively included seventy-three patients with histologically proven breast cancer who underwent preoperative DBT, ABVS and 1.5 T MRI in the period July 2015-July 2016. Two radiologists in consensus recorded the number, site and Breast imaging-reporting and data system (BI-RADS) category of breast findings during two independent reading strategies, i.e. DBT-ABVS vs. MRI. Using histology or 1-year follow up as the standard of reference, we calculated the accuracy for cancer of both imaging strategies. Bland-Altman analysis was used to evaluate the agreement between MRI vs. DBT or ABVS in cancer size assessment. RESULTS: Patients showed a total of 160 lesions (108 malignant and 52 benign). Malignant lesions were unifocal, multifocal, multicentric and biltateral in 53, 15, 4 and 1 cases, respectively. Diagnostic accuracy of DBT-ABVS vs. MRI was comparable for all cancers (90.0% [95%C.I. 84.3-94.2] vs. 93.8% [95%C.I. 88.8-97.0], respectively). DBT-ABVS showed lower sensitivity and positive predictive values for additional disease (76.5% [95%C.I. 58.8-89.3] vs. 91.7% [95%C.I. 84.6-96.1], and 78.8% [95%C.I. 61.0-91.0] vs 93.4% [95%C.I. 86.9-97.3], respectively). Compared to MRI, ABVS + DBT missed 6 lesions, including two invasive cancers and one extensive intravascular invasion associated to ductal carcinoma in situ. Bland-Altman analysis showed ABVS to agree with MRI at a higher extent than DBT in assessing cancer size. CONCLUSIONS: Though less performing than MRI, DBT-ABVS showed acceptable diagnostic accuracy in staging breast cancer. This strategy might be used if MRI is unavailable or unfeasible. PMID- 30292266 TI - Clinical implication of radiographic scores in acute Middle East respiratory syndrome coronavirus pneumonia: Report from a single tertiary-referral center of South Korea. AB - The aim of this study is to determine the earliest cutoff of radiographic score as a potential prognostic indicator of fatal outcomes in patients with acute Middle East respiratory syndrome coronavirus (MERS-CoV) pneumonia. The institutional review board approved this retrospective study. Serial chest radiographies (CXRs) were obtained from viral exposure until death or discharge in 35 patients with laboratory confirmed MERS-CoV infection. Radiographic scores were calculated by multiplying a four-point scale of involved lung area and three point scale of abnormal opacification, in each of the six lung zones. Receiver operating characteristics (ROC) analyses were performed to identify optimal day and radiographic score for the prediction of respiratory distress, and univariate and multivariate logistic regression analyses were performed to assess significant predictive factors for intubation or tracheostomy. Among 35 patients (22 men, 13 women; median age: 48 years), 25 demonstrated abnormal opacity on CXR (MERS pneumonia), whereas no abnormality was detected in 10 patients (MERS upper respiratory tract infection). Seven patients required ventilator support (intubation group) and three of them eventually expired. The average incubation period was 5.4 days (standard deviation, +/-2.8; range, 2-11). Patients in the intubation group had a higher incidence of diffuse lung involvement, higher radiographic scores, and fibrosing sequela on follow up study compared with those in the non-intubation group. However, patients' age and comorbidity did not differ significantly between the two groups. The ROC analysis revealed an area under curve of 0.726 for the radiographic score on day 10 with an optimal cutoff score of 10 for prediction of intubation, with a sensitivity of 71% and specificity of 67%. Our study suggest that MERS patients with radiographic score > 10 on day 10 from viral exposure require aggressive therapy with careful surveillance and follow-up evaluation. PMID- 30292267 TI - Diagnostic value of diffusion-weighted imaging and 18F-FDG-PET/CT for the detection of unknown primary head and neck cancer in patients presenting with cervical metastasis. AB - BACKGROUND AND PURPOSE: Head and neck squamous cell carcinoma (HNSCC) may present with cervical metastases without an apparent primary tumor. Detecting the primary tumor results in more targeted treatment. Acquisition of DWI is improving with less artifacts and image distortion. We assessed the diagnostic value of DWI and 18F-FDG-PET/CT for detecting primary tumors in patients presenting with nodal metastasis of an unknown primary HNSCC. MATERIALS AND METHODS: For this retrospective study we included 31 patients (male/female ratio = 23/8, median age = 66 years, age range = 40-80 years) who presented with a pathologically proven cervical nodal metastasis from HNSCC without overt primary tumor location between January 2013 and November 2016 and underwent both DWI and 18F-FDG-PET/CT. Both modalities were assessed qualitatively and quantitatively. With ROC analysis we determined the optimal cut-off for imaging parameters in separating occult malignancy from benign tissue. RESULTS: Qualitative analysis of MRI including DWI resulted in a sensitivity of 81.3% (95%CI) = 53.7-95.0) and specificity of 73.3% (95%CI = 44.8-91.1). With qualitative scoring of 18F-FDG-PET/CT a sensitivity and specificity of 93.8% (95%CI = 67.8-99.7) and 73.3% (95%CI = 44.8-91.1) were found. With quantitative analysis sensitivity and specificity of SUVmax were 81.3% (95%CI = 53.6-95.0) and 93.3% (95%CI = 66.0-99.7), respectively. Combining DWI and 18F-FDG-PET/CT resulted in a sensitivity of 93.8% (95%CI = 67.7-99.7%) and specificity of 60.0% (95%CI = 32.9-82.5%). CONCLUSION: In this study on HNSCC patients presenting with clinically UP lesions the diagnostic accuracy of qualitative analysis with DWI and 18F-FDG-PET/CT and quantitative analysis of 18F FDG-PET/CT using SUVmax were high. Adding DWI did not improve the accuracy of 18F FDG-PET/CT. PMID- 30292268 TI - Native cardiac T1 Mapping: Standardized inline analysis of long and short axis at three identical 1.5 Tesla MRI scanners. AB - BACKGROUND: Interpretation of native T1 time values remains difficult due to limited hard- and software comparability and the lack of measurement recommendations for the number of slices and their orientation. To provide a standardized comparison of native T1 time values in short and long axis and to investigate the interscanner reproducibility. METHODS: 78 cardiac MRIs in 26 healthy volunteers were performed with three structurally identical 1.5 T MRI scanners. A commercially available software package for T1 mapping with automatic in-line motion correction was used for analysis. On T1 mapping images regions of interest were manually placed in each of the 16 myocardial segments according to the AHA model in three short and three long axis. RESULTS: A total of 2652 ROIs were drawn and 102 segments per volunteer were analysed. Interscanner reproducibility was high and the mean myocardial T1 time value for all evaluated segments was 996 +/- 34 ms. Significant variations of T1 time values were found between heart segments in the same axis. Mean T1 time values were comparable between long and short axis but differed in 33% of corresponding short and long axis segments. CONCLUSIONS: Native T1 time values in short and long axis are highly reproducible but can vary significantly between heart segments in the same axis. Comparability between corresponding short and long axis segments is limited. To get representative results native T1 time values should be obtained in more than one heart segment and for follow-up studies identical segments should be used to avoid a systematic bias. PMID- 30292269 TI - Radiological images of interstitial pneumonia in mixed connective tissue disease compared with scleroderma and polymyositis/dermatomyositis. AB - OBJECTIVE: Little has been reported on the radiological and pathological findings of interstitial pneumonia in mixed connective tissue disease (MCTD). There may be possible difference in treatment response and prognosis between the imaging patterns of systemic sclerosis (SSc)-like and polymyositis/dermatomyositis (PM/DM)-like. The purpose of this study was to examine whether the radiological images of interstitial pneumonia in MCTD presented SSc-like or PM/DM-like pattern, and to assess whether the imaging patterns corresponded to clinical and pathological features. MATERIALS AND METHODS: This retrospective study included 29 patients with interstitial pneumonia who underwent surgical lung biopsy; 10 with SSc, 10 with PM/DM, and 9 with MCTD. High resolution computed tomography (HRCT) images were classified as SSc, PM/DM, or the other pattern by two radiologists independently without clinical information. The pathology of the lung specimens from MCTD patients were evaluated and compared with the imaging pattern. RESULTS: The concordance rate between clinical diagnosis and radiological pattern was 100% in SSc patients, and 80% in PM/DM patients. Among patients with MCTD, imaging patterns were classified as SSc pattern in 4 (MCTD SSc), PM/DM pattern in 4 (MCTD-PM/DM) and other in one. The imaging patterns did not always correlate with the clinical findings in MCTD patients. Pathologically, plasma cell infiltration and organizing pneumonia were relatively more frequent in MCTD-PM/DM, and smooth muscle hyperplasia was relatively more frequent in MCTD SSc. CONCLUSION: HRCT images in MCTD patients can be classified as SSc pattern or PM/DM pattern. MCTD-SSc and MCTD-PM/DM were corresponded to similar pathological findings of SSc and PM/DM. PMID- 30292270 TI - Quantitative CT detects changes in airway dimensions and air-trapping after bronchial thermoplasty for severe asthma. AB - OBJECTIVES: Bronchial thermoplasty (BT) can be considered in the treatment of severe asthma to reduce airway smooth muscle mass and bronchoconstriction. We hypothesized that BT may thus have long-term effects on airway dimensions and air trapping detectable by quantitative computed tomography (QCT). METHODS: Paired in and expiratory CT and inspiratory CT were acquired in 17 patients with severe asthma before and up to two years after bronchial thermoplasty and in 11 additional conservatively treated patients with serve asthma, respectively. A fully automatic software calculated the airways metrics for wall thickness (WT), wall percentage (WP), lumen area (LA) and total diameter (TD). Furthermore, lung air-trapping was quantified by determining the quotient of mean lung attenuation in expiration vs. inspiration (E/I MLA) and relative volume change in the Hounsfield interval -950 to -856 in expiration to inspiration (RVC856-950) in a generation- and lobe-based approach, respectively. RESULTS: BT reduced WT for the combined analysis of the 2nd-7th airway generation significantly by 0.06 mm (p = 0.026) and WP by 2.05% (p < 0.001), whereas LA and TD did not change significantly (p = 0.147, p = 0.706). No significant changes were found in the control group. Furthermore, E/I MLA and RVC856-950 decreased significantly after BT by 12.65% and 1.77% (p < 0.001), respectively. CONCLUSION: BT significantly reduced airway narrowing and air-trapping in patients with severe asthma. This can be interpreted as direct therapeutic effects caused by a reduction in airway smooth muscle mass and changes in innervation. A reduction in air-trapping indicates an influence on more peripheral airways not directly treated by the BT procedure.

AB - PURPOSE: To retrospectively determine the frequency, natural history and factors associated with the presence of transient hepatic enhancement difference showing hypointensity on hepatobiliary phase images of gadoxetic acid-enhanced MRI. MATERIALS AND METHODS: Gadoxetic acid-enhanced MRI of 125 patients (91 men; 34 women) with transient hepatic enhancement difference were retrospectively reviewed. Three readers qualitatively and quantitatively evaluated MR imaging features and evolution at follow up. The Chi-square test, Fisher's exact test and Kruskall-Wallis rank test were used for statistical analysis. RESULTS: Transient hepatic enhancement difference were hypointense on hepatobiliary phase images in 20 of 125 cases (16%). At univariate analysis there was association with wedge shape morphology (p < 0.001), size >=21 mm (p < 0.001), hyperintensity on T2 weighted imaging (p < 0.001), restricted diffusion (p < 0.001) and previous treatment (p < 0.005). At multivariate analysis, the following factors were associated: previous treatment (p < 0.05), hyperintensity on T2-weighted imaging (p < 0.001) and size >=21 mm (p < 0.001). Of 12 patients with hypointense transient hepatic enhancement difference on hepatobiliary phase images who had follow-up MRI, nine showed reduction in size. CONCLUSION: Transient hepatic enhancement difference observations showing hypointensity on hepatobiliary phase images of gadoxetic acid-enhanced MRI are not infrequent and may shrink at follow up. They are more likely associated with size >=21 mm, hyperintensity on T2 weighted images and previous treatment of adjacent tumor. PMID- 30292272 TI - Magnetic resonance elastography of healthy livers at 3.0 T: Normal liver stiffness measured by SE-EPI and GRE. AB - PURPOSE: To determine the normal liver stiffness values using magnetic resonance elastography (MRE) at 3.0 T and to compare spin-echo echo-planar imaging (SE-EPI) and gradient-recalled-echo (GRE) MRE. MATERIALS AND METHODS: This retrospective study included 54 living liver donors who had normal clinical and pathological results without underlying liver disease and underwent MRE using both SE-EPI and GRE at 3.0 T. Two radiologists placed four or six freehand regions of interest (ROI) on the elastograms and measured liver stiffness as well as the area of ROIs. The mean liver stiffness values and area of ROIs were compared between genders, among age groups, and between groups of different body mass indexes using the t-test and one-way analysis of variance, respectively. Interobserver agreement was analyzed using intraclass correlation coefficient. The mean liver stiffness values and area of ROIs were compared between SE-EPI and GRE using the paired t-test and Bland-Altman analysis. RESULTS: The liver stiffness values in living liver donors ranged from 1.52 to 3.12 kPa on SE-EPI and 1.51 to 2.67 kPa on GRE. The mean liver stiffness values did not differ significantly according to the gender, age, and body mass index. Measurement of liver stiffness using MRE showed excellent interobserver agreement on both pulse sequences. The mean value of liver stiffness was higher on SE-EPI (2.14 +/- 0.33 kPa) than on GRE (2.06 +/- 0.25 kPa), and the difference was statistically significant (P < 0.05). The mean area of ROI was significantly larger with GRE (3387 mm2) than with SE-EPI (2691 mm2) (P < 0.05). CONCLUSIONS: The mean liver stiffness values in living donors measured by SE-EPI and GRE were not affected by gender, age, or body mass index and showed excellent interobserver agreement. The area of ROI was larger with GRE than with SE-EPI. PMID- 30292273 TI - CT temporal subtraction method for detection of sclerotic bone metastasis in the thoracolumbar spine. AB - PURPOSE: To assess the effectiveness of a CT temporal subtraction (TS) method on radiologists' performance in sclerotic metastasis detection in the thoracolumbar spine. MATERIALS AND METHODS: 20 pairs (current and previous CTs) of standard dose CT and their TS images in patients with sclerotic bone metastasis and 20 pairs (current and previous CTs) of those in patients without bone metastasis were used for an observer performance study. A total of 135 lesions were identified as the reference standard of actionable lesions (sclerotic metastasis newly appeared or increased in size or in attenuation). 4 attending radiologists and 4 radiology residents participated in this observer study. Ratings and locations of "lesions" determined by the observers were utilized for assessing the statistical significance of differences between radiologists' performances without and with the CT-TS images in JAFROC analysis. The statistical significance of differences in the reviewing time was determined by a two-tailed paired t-test. RESULTS: The average figure-of-merit (FOM) values for all but one radiologist increased to a statistically significant degree, from 0.856 without the CT-TS images to 0.884 with the images (P = .037). The average sensitivity for detecting the actionable lesions was improved from 60.7 % to 72.5% at a false positive rate of 0.15 per case by use of the CT-TS images. The average reading time with CT-TS images was significantly shorter than that without (150.6 s vs. 166.5 s, P = .004). CONCLUSION: The use of CT-TS would improve the observer performance for the detection of the sclerotic bone metastasis in the thoracolumbar spine. PMID- 30292274 TI - Metal artifact reduction techniques in musculoskeletal CT-imaging. AB - It is known that metal artifacts can be reduced by modifying standard acquisition and reconstruction, by modifying projection data and/or image data and by using virtual monochromatic imaging extracted from dual-energy CT. In this review we focus on the origin of metal artifacts, technical background of commercially available metal artifact reduction (MAR) algorithms and the value of dual-energy CT and MAR software for different metal hardware in current clinical practice. Virtual monochromatic imaging reduces beam-hardening artifacts, where metal artifact reduction software effectively reduces artifacts caused by extensive photon-starvation. Both techniques have their advantages and disadvantages, and the combination of both techniques is often but not always the best solution regarding metal artifact reduction. Advances in prosthetic imaging are reinforced by advances in prosthetic design. Providing implant specific information prior to scanning is important in order to adjust the metal artifact reduction approach, minimize artifacts and optimize image quality and diagnostic value of CT. PMID- 30292275 TI - Validation of water-fat MRI and proton MRS in assessment of hepatic fat and the heterogeneous distribution of hepatic fat and iron in subjects with non-alcoholic fatty liver disease. AB - BACKGROUND: Research studies demonstrated pathologic lesions were unevenly distributed in patients with non-alcoholic fatty liver disease (NAFLD) and non alcoholic steatohepatitis. As hepatic steatosis occurs prior to steatohepatitis and other late stage liver conditions, the distribution pattern of hepatic fat and iron concentration should be investigated to prevent sampling variability. The first purpose of this study was to perform comparison and validation of in house hepatic fat measurements using water-fat MRI and MRS. The second objective was to quantify hepatic fat-fraction and T2* values in left and right liver lobes using water-fat MRI. METHOD: Fifty-four non-alcoholic adults (27 NAFLD, age: 42.8 +/- 11.8), 27 non-NAFLD, age: 45.5 +/- 11.2) and 46 non-alcoholic teenagers (23 NAFLD (age: 15.4 +/- 2.6), 23 non-NAFLD (age: 13.9 +/- 2.3) were recruited. All participants underwent chemical shift water-fat MRI and 1H MRS at 3 T. Hepatic steatosis was defined by intrahepatic triglyceride more than the threshold of 5.56% using MRS (clinical reference) and non-alcoholic was defined by alcohol ingestion of no more than 30 g and 20 g per day for male and female respectively. Hepatic fat-fractions in left and right liver lobes were measured using regions of-interest (ROIs) approach. Three ROIs were drawn on the fat-fraction images and duplicated on to the co-registered T2* images at the inferior right, superior right and superior left liver lobes. Comparison and validation of water-fat MRI and MRS were performed using intraclass correlation coefficient (ICC) and Bland Altman plot. Hepatic fat-fraction and T2* measured from the ROIs were compared using repeated measures ANOVA. Independent t-test was used for between groups analysis. RESULTS: Statistical analysis indicated good correlation (R = 0.987) and agreement (ICC = 0.982) between MRS and water-fat MRI in hepatic fat measurements. Results indicated that hepatic fat was significantly higher in the right lobe compared to the left in NAFLD adults (p < 0.001) and NAFLD teenagers (p < 0.001). For T2*, significant difference between left and right lobes was observed in NAFLD adults (p < 0.001) and non-NAFLD adults (p < 0.001) but not in teenagers. CONCLUSION: Hepatic fat measurements using MRS and water-fat MRI are statistically equivalent. In subjects with NAFLD regardless of their age, hepatic fat is stored preferentially in the right live lobe probably due to the streamline of blood flow to the right liver. T2* value is significantly higher in the right liver lobe in adults but not in the teenagers regardless of their hepatic fat contents probably due to the longer time span of hepatic iron accumulation. PMID- 30292276 TI - Crossed cerebellar diaschisis in post-treatment glioma patients: A comparative study of arterial spin labelling and dynamic susceptibility contrast. AB - OBJECTIVES: To assess crossed cerebellar diaschisis (CCD) in post-treatment glioma patients, and to compare the performance of arterial spin labelling (ASL) and dynamic susceptibility contrast (DSC) in detecting CCD. METHODS AND MATERIALS: This retrospective study included 130 patients who had both DSC and ASL. Among them, 16 had underwent fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT). We investigated the relationship between CCD and the location and size of supratentorial lesions, and compared PET diagnostic performance with that of ASL and DSC. We assessed the inter-methods agreement for ASL and DSC, and performed quantitative analysis by calculating the asymmetry index (AI) between bilateral cerebellum and exploring how the AI values for ASL-CBF, DSC-rCBF, and DSC-rCBV maps correlated with each other. RESULT: Supratentorial lesions affecting the corona radiata (P < 0.001), basal ganglia (P < 0.001), and insula (P = 0.046) were significantly associated with the occurrence of CCD. Lesion size was significantly larger (P = 0.005) in the CCD positive group. With PET as a reference, ASL-CBF and DSC-rCBF maps exhibited the best diagnostic performance compared with the other DSC-generated maps (diagnostic accuracy = 83.3% for both, area under curve (AUC) of ASL = 0.967, AUC of rCBF = 0.983), although differences were not statistically significant. The kappa value for the inter-methods (ASL and DSC) agreement in detecting CCD was 0.893, while the degree of perfusion asymmetry was more significant in ASL- than DSC-generated maps. Bland-Altman plots showed that the AI for ASL-CBF was moderately correlated with those for DSC-rCBF and DSC-rCBV. CONCLUSIONS: CCD can present in post-treatment glioma patients and is detectable on MR-perfusion images including ASL-CBF, DSC-rCBF, and DSC-rCBV maps. PMID- 30292277 TI - Myocardial T1 and T2 mapping in severe aortic stenosis: Potential novel insights into the pathophysiology of myocardial remodelling. AB - PURPOSE: Severe aortic stenosis (AS) is known to be associated with substantial myocardial remodelling, leading to diffuse myocardial fibrosis (DMF). Native myocardial T1 is emerging as a novel imaging biomarker for the non-invasive assessment of DMF. In contrast, no studies exist elucidating changes of myocardial T2 reflecting myocardial oedema in the presence of AS. The purpose of the present study was to combine native T1 and T2 mapping in order to characterize myocardial tissue changes in the setting of severe AS. METHODS: After obtaining ethical approval and informed consent, a total of 26 prospectively selected patients with severe AS (13 women, mean age 81 +/- 7 years) and 17 healthy controls (12 women, mean age 63 +/- 6 years) underwent cardiac magnetic resonance (CMR) imaging on a clinical 3 T scanner. The CMR protocol included a native Modified Look-Locker (MOLLI) T1 mapping and a Gradient Spin Echo (GraSE) T2-mapping sequence in three short-axis slices and one long axis view. After segmentation, myocardial T1 and T2 values were averaged over the entire myocardium. Statistical analysis was performed using Wilcoxon sum-rank test, Welch's independent t-test and Pearson's correlation coefficient. RESULTS: Global native myocardial T1 was significantly increased in AS patients when compared to controls (1305 +/- 39 vs. 1272 +/- 21 ms, p = .005). Similarly, mean myocardial T2 was significantly elevated in AS patients (51 +/- 4 vs. 46 +/- 2 ms, p < .001) and showed a strong correlation with native T1 (r = .60, p < .001). An overlap was observed between T1 of both groups, whereas T2 discriminated nearly perfectly between the two groups (area under the curve in ROC analyses: 0.76 for T1, 0.87 for T2). CONCLUSIONS: Patients with severe AS exhibit significantly elevated native myocardial T1, which has previously been shown to correlate with the amount of myocardial collagen. Adding to this evidence, the present study is the first to show that native T1 and T2 are both significantly elevated and correlated in AS patients, pointing towards a potential role of oedematous/inflammatory processes in the pathophysiology of myocardial remodelling associated with AS. PMID- 30292278 TI - Single extracorporeal shock-wave lithotripsy for proximal ureter stones: Can CT texture analysis technique help predict the therapeutic effect? AB - PURPOSE: To explore whether the computed tomography texture analysis (CTTA) technique can help predict the curative effects of a single extracorporeal shock wave lithotripsy (ESWL) for proximal ureteral stones. MATERIALS AND METHODS: In all, 100 patients with proximal ureteral stone underwent non-enhanced multi detector computed tomography (MDCT) before ESWL. The patients were divided into success and failure groups. Success of ESWL was defined as the patients being stone-free or having residual stone fragments of <=2 mm. Traditional characteristics, such as stone size, body mass index (BMI), and skin-to-stone distance (SSD), and CTTA metrics, such as the mean Hounsfield unit (HU) density, entropy, kurtosis, and skewness, were analyzed and compared between two groups by univariate and multivariate logistic regression analyses. Receiver operating characteristic (ROC) curves were generated to determine Youden index-based cutoff values. RESULT: Failure of stone removal was observed in 36 patients (36%). Stone height, stone cross-sectional diameter, largest cross-sectional area, stone volume, stone density (mean HU), and CTTA metrics (kurtosis and entropy) were the significant independent predictors of ESWL success on univariate analysis (p < 0.05). On multivariate analysis, mean HU, skewness, and kurtosis were shown to be significant predictors of ESWL success (p < 0.05). In subgroup analysis based on the cutoff value of mean stone density (HU = 857), the only significant independent factor associated with both subgroups was kurtosis (p < 0.05). CONCLUSIONS: As a quantitative analysis method, CTTA may be helpful in selecting appropriate ESWL patients. High kurtosis and low mean HU values simultaneously indicate a relatively higher ESWL success rate. PMID- 30292279 TI - CT texture analysis can be a potential tool to differentiate gastrointestinal stromal tumors without KIT exon 11 mutation. AB - OBJECTIVE: To evaluate CT texture analysis as a tool to differentiate gastrointestinal stromal tumors (GISTs) without KIT exon 11 mutation. MATERIALS AND METHODS: This study consisted of a study group of 69 GISTs and a validation group of 17 GISTs. Clinical information of the patients were collected and analyzed. Two-dimensional and three-dimensional texture analysis was performed. The textural parameters were evaluated in the study group and were validated in the validation group. The repeatability of the textural parameters on the single region of interest (single-ROI), double-ROI, and whole volume of interest (whole VOI) was analyzed. The independent predictor for the GIST genotypes was analyzed with logistic regression models. The support vector machine (SVM) classifiers were also trained and 6-fold cross validation ROC curves were computed. Subjective heterogeneity scores of each lesion on enhanced CT images were given by radiologists and the corresponding difference of the heterogeneity rating was evaluated. RESULTS: The non-gastric location, lower CD34_stain level and higher textural parameter standard Deviation (stdDeviation) were associated with the GISTs without KIT exon 11 mutation in the study group. The cross validation SVM classifiers achieved with combination of stdDeviation, anatomic location and CD34_stain level demonstrated medium to good prediction efficiency (AUC = 0.864 0.904) regarding the GIST genotypes. The stdDeviation was an independent predictor of GISTs without KIT exon 11 mutation, and had a medium correlation with the GIST genotypes in the study group (AUC = 0.726-0.750). The stdDeviation showed good performance (AUC = 0.904-0.962) when validated in the validation group. The double-ROIs improved the performances of single-ROIs, decreasing the variances of single-ROIs brought by section-selection, and demonstrating excellent agreements between ROIs and whole-VOI. Subjective heterogeneity scores had no statistically significant differences between GIST genotypes. CONCLUSION: CT texture analysis can potentially help to differentiate GISTs without KIT exon 11 mutation from those GISTs with KIT exon 11 mutation on enhanced CT images. PMID- 30292280 TI - Computed tomography findings of arc-welders' pneumoconiosis: Comparison with silicosis. AB - OBJECTIVE: Arc-welders' pneumoconiosis (AWP) is a less fibrogenic pneumoconiosis with radiographic shadows that can improve after isolation from dusty environments. Therefore, early diagnosis is important. However, the exact role of chest radiograph and computed tomography (CT) for diagnosing AWP is not fully understood. This study was performed to assess the CT appearance of AWP using semi-quantitative methods and to compare the findings with those of silicosis. The profusion of pulmonary abnormality on chest radiograph were also compared with the semi-quantitative CT score. MATERIALS AND METHODS: Sixty-six patients with clinically diagnosed AWP were included and compared with 33 patients with silicosis. The CT images were interpreted according to the International Classification of HRCT for Occupational and Environmental Respiratory Diseases (ICOERD). Data on the profusion score by chest radiograph were also compared with CT score. RESULTS: Ill-defined centrilobular nodules, ground-glass opacity (GGO) and centrilobular branching opacity were more frequently observed (p = 0.0031) in AWP, whereas well-defined rounded opacity (p < 0.0001), progressive massive fibrosis (p < 0.0001), and mediastinal lymphadenopathy (p < 0.0001) were more frequently observed in silicosis. Regarding lung nodules, there was a high correlation between the ICOERD and CXR profusion scores in silicosis, but CXR underestimated AWP. CONCLUSION: Ill-defined centrilobular nodules, GGO and centrilobular branching opacity were more frequently observed in AWP than silicosis. Because these findings are difficult to detect by chest radiograph, CT should be considered for the assessment of patients with suspected AWP. PMID- 30292281 TI - Outcomes and Safety of Transcatheter Aortic Valve Implantation With and Without Routine Use of Transesophageal Echocardiography. AB - Transesophageal echocardiography (TEE) has been extensively used historically for Transcatheter aortic valve implantation (TAVI) but focus is shifting from routine use of TEE and general anesthesia to "as needed" use. We evaluated patients who had TAVI in our institution from September 2012 to February 2017. Decision for implantation and use of TEE during procedure was made by the structural heart team on a case-to-case basis, based on FDA approved indications. Data including procedural details, length of stay and rehospitalizations were obtained from all patients. TAVI was performed on 178 patients during the study period of which 104 of 178 had TEE during TAVI. Baseline characteristics were fairly comparable in both groups. Similar proportion of self-expanding and balloon expanding valves were deployed. Patients in TEE group had longer overall procedure time (107 minute vs 83 minute, p = 0.0002) and longer length of stay (5.01days vs 2.49days, p < 0.0001). Echocardiographic study postprocedure showed similar incidence of paravalvular leak and similar gradients and velocities across aortic valve. Rates of 30-day readmissions were similar in both groups. In conclusion, in this single center retrospective analysis-TAVI without the 'routine use' of TEE was comparable with those done with TEE guidance in terms of periprocedural complications and 30-day readmissions. Overall procedure length and length of stay was predictably higher in the TEE group. PMID- 30292282 TI - Effects of Gestational Age on Early Survivability in Neonates With Hypoplastic Left Heart Syndrome. AB - Prematurity increases pre- and postoperative mortality in children with congenital heart disease. There are no large, multicentered, studies that have evaluated this relation specifically in neonates with hypoplastic left heart syndrome (HLHS). We sought to determine the impact of gestational age (GA) on survival to Stage 1 palliation surgery and hospital discharge in infants with HLHS. We reviewed data from 1,913 neonates with HLHS born at or transferred to a Vermont Oxford Network expanded member hospital in the United States from 2009 to 2014. Demographic, diagnostic, and surgical codes, and outcome data within the Vermont Oxford Network database were used to determine the effect of GA and birth weight on survival to Stage 1 palliation surgery and hospital discharge. Risk models were developed controlling for common confounders to determine the relative risk of GA on the observed outcomes. These data demonstrate that, when compared with 39-week infants, those born at earlier GA were less likely to survive until surgery; <34 weeks adjusted risk ratio (ARR) for survival: 0.47 (95% confidence interval 0.37 to 0.60), 34 to 35 weeks ARR 0.73 (0.62 to 0.87), and 36 to 37 weeks ARR 0.88 (0.83 to 0.94). Higher GA also positively correlated with survival to hospital discharge, although there was no difference in 34 to 35 week infants and 36 to 37-week infants. In conclusion, these data show that GA was an independent risk factor for survival to Stage 1 palliation surgery and survival to hospital discharge. However, there is no significant difference in survival to hospital discharge between infants born in 34 to 37 weeks gestation. PMID- 30292283 TI - Preface. PMID- 30292284 TI - The Schistosoma mansoni lipidome: Leads for immunomodulation. AB - Schistosoma mansoni is a parasitic helminth that infects millions of people mostly in tropical parts of the world. Different life cycle stages of S.mansoni, that infect or develop in the human host, promote distinct immune responses and are known for their ability to modulate host immune responses. However, the molecular mechanisms through which the parasites interact with, and modulate the host immune system remain incompletely understood. Despite the well-known ability of various lipids to modulate immune responses, a comprehensive analysis of the lipidome of the different life cycle stages has not been performed. Using three complementary MS-based platforms to detect and quantify around 350 lipid species, we here characterized the lipid profiles of S. mansoni cercariae, worms and eggs, as well as extracts and excretory/secretory (ES) products of different life cycle stages of S. mansoni. We identified life cycle stage specific signatures of lipid classes of which cercariae were found to have the most distinct profile. Moreover, we detected several immunolomodulatory oxylipids in the different life cycle stages. Specifically, prostaglandins were found to be most highly enriched in egg preparations, while resolvins were specifically detected in cercariae. Together, the generation of this detailed lipid database of the different life cycle stages of S. mansoni will not only be important for a better understanding of the biology of the parasite itself but also of host-parasite interactions and how that could result in immunomodulation. PMID- 30292285 TI - Serially coupled reversed phase-hydrophilic interaction liquid chromatography tailored multiple reaction monitoring, a fit-for-purpose tool for large-scale targeted metabolomics of medicinal bile. AB - The acquisition of high-quality quantitative dataset is the prerequisite for large-scale targeted metabolomics. However, the goal is usually dampened by the complexity of the biological matrices in terms of structural diversity, concentration span, and polarity range. We attempted herein to propose an analytical approach being able to circumvent these technical obstacles, and medicinal bile was employed as a proof of concept. In the liquid chromatography (LC) domain, reversed phase LC and hydrophilic liquid interaction chromatography were coupled in series, namely RPLC-HILIC, to yield appropriate chromatographic behavior for each component regardless of the polarity. In-depth chemical characterization and widely quantitative analysis were successively conducted in the mass spectrometry (MS) domain. Hybrid ion trap-time of flight MS was jointly deployed with hybrid triple quadrupole-linear ion trap MS for metabolite searching because of their orthogonal natures. Afterwards, a tailored MRM strategy that integrated online parameter optimization, ion intensity tailoring, and scheduled monitoring, was subsequently constructed to accomplish comprehensive quantitation although authentic compounds weren't involved and concentration span was quite large. Calibration curve was constructed for each detected identity by preparing and serially diluting the universal metabolome standard (UMS) solution that merged chemical information from all bile samples. Quasi-contents of 164 components including bile acids, sterols, eicosanoids, amino acids, lipids, flavonoids, and so forth, were gained by applying those regressive calibration curves and replaced the role of peak areas to serve as the variables for multivariate statistical analysis. In particular, the concentration ratio between tauroursodeoxycholic acid (TUDCA) and taurohyodeoxycholic acid (THDCA) that were exactly co-eluted as a single peak was calculated from the intensity specific value of m/z 498 > 80 over 498 > 124. Different metabolome occurred among various animal bile samples, and significant variations were also observed for different batches of bear bile powders. Bile acids acted as the indicative components in either discrimination. Overall, RPLC-HILIC-tailored MRM enabled quantitative metabolome profiling of medicinal bile and was thereby a promising analytical tool for large-scale targeted metabolomics. PMID- 30292286 TI - Dark matter in host-microbiome metabolomics: Tackling the unknowns-A review. AB - The "dark matter" in metabolomics (unknowns) represents an exciting frontier with significant potential for discovery in relation to biochemistry, yet it also presents one of the largest challenges to overcome. This focussed review takes a close look at the current state-of-the-art and future challenges in tackling the unknowns with specific focus on the human gut microbiome and host-microbe interactions. Metabolomics, like metabolism itself, is a very dynamic discipline, with many workflows and methods under development, both in terms of chemical analysis and post-analysis data processing. Here, we look at developments in the mutli-omic analyses and the use of mass spectrometry to investigate the exchange of metabolites between the host and the microbiome as well as the environment within the microbiome. A case study using HuMiX, a microfluidics-based human microbial co-culture system that enables the co-culture of human and microbial cells under controlled conditions, is used to highlight opportunities and current limitations. Common definitions, approaches, databases and elucidation techniques from both the environmental and metabolomics fields are covered, with perspectives on how to merge these, as the boundaries blur between the fields. While reflecting on the number of unknowns remaining to be conquered in typical complex samples measured with mass spectrometry (often orders of magnitude above the "knowns"), we provide an outlook on future perspectives and challenges in elucidating the relevant "dark matter". PMID- 30292287 TI - Metabolomics studies on db/db diabetic mice in skeletal muscle reveal effective clearance of overloaded intermediates by exercise. AB - Type 2 diabetes mellitus (T2DM) is characterized by hyperinsulinemia, hyperglycemia and insulin resistance, which correlated with high mortality worldwide. Exercise is one of the effective lifestyle interventions in maintaining blood glucose level in the normal range and lowering risk factors. Metabolomics approaches are powerful tools in systematic study of overall metabolic changes in response to disease or interventions. In this study, mass spectrometry-based metabolomics studies were performed to investigate the regulatory effect of moderate intensity of exercise on db/db diabetic mice in skeletal muscle. Both liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS) have been carried out to monitor a wide range of regulated metabolites. Ninety-five metabolites were identified which contributing to the discrimination of db/m + control and db/db diabetic mice. The regulatory effects of exercise on these metabolites were mainly focusing on attenuating the levels of long-chain fatty acids (C14 to C18) and medium-to long chain acylcarnitines (C12 to C18), indicated that exercise might play a positive role in inhibiting the accumulation of excessive lipids, which is positively related to insulin resistance. In addition, uric acid, which is a risk factor for inflammation, cardiovascular complications, and fatty liver in diabetic patients, together with its intermediates (such as inosinic acid, hypoxanthine, etc.) in purine metabolism pathway, were also substantially down regulated after exercise, indicating exercise might also be protective against hyperuricemia related risks in T2DM. These findings reveal that moderate intensity of exercise might play a positive role in improving the efficiency of lipid metabolism in skeletal muscle and meanwhile enhancing uric acid clearance to prevent lipid accumulation, which might contribute to improved body fitness and body muscle composition. PMID- 30292288 TI - Metabolomics study of early metabolic changes in hepatic HepaRG cells in response to rosemary diterpenes exposure. AB - Rosemary diterpenes have demonstrated diverse biological activities, such as anti cancer, antiinflammatory, as well as other beneficial effects against neurological and metabolic disorders. In particular, carnosic acid (CA), carnosol (CS) and rosmanol (RS) diterpenes have shown interesting results on anti-cancer activity. However, little is known about the toxic effects of rosemary diterpenes at the concentrations needed to exert their antiproliferative effect on cancer cells. In our study, CA, CS and RS exhibited a concentration-dependent effect on cell viability of two human colon cancer cell lines (HT-29 and HCT116) after 24 h exposure. HT-29 cell line was more resistant to the inhibitory effect of the three diterpenes than HCT116 cell line. Among the three diterpenes, RS exerted the strongest effect in both cell lines. To investigate the hepatotoxicity of CA, CS and RS, undifferentiated and differentiated HepaRG cells were exposed to increasing concentrations of the diterpenes (from 10 to 100 MUM). Differentiated cells were found to be more resistant to the toxic activity of the three diterpenes than undifferentiated HepaRG, probably related to a higher detoxifying function of differentiated HepaRG cells compared with the undifferentiated cells. The metabolic profiles of differentiated HepaRG cells in response to CA, CS and RS were examined to determine biochemical alterations and deepen the study of the effects of rosemary phenolic diterpenes at molecular level. A multiplatform metabolomics study based on liquid- and gas-chromatography hyphenated to high resolution mass spectrometry revealed that rosemary diterpenes exerted different effects when HepaRG cells were treated with the same concentration of each diterpene. RS revealed a greater metabolome alteration followed by CS and CA, in agreement with their observed cytotoxicity. Metabolomics provided valuable information about early events in the metabolic profiles after the treatment with the investigated diterpenes from rosemary. PMID- 30292289 TI - An integrated method for direct interrogation of sphingolipid homeostasis in the heart and brain tissues of mice through postnatal development up to reproductive senescence. AB - Development of rapid metabolomic methods poised for pathway discovery is expected to facilitate the identification of therapeutic candidates in the metabolomic approach to translational medicine. Using sphingolipid homeostasis as a prototype, we present herein an integrated method to facilitate a fast interrogation of altered sphingolipid (and phospholipid) metabolism associated with perturbed endolysosomal functions in mammalian systems. Constructed upon high performance liquid chromatography coupled to mass spectrometry, this method allows semi-quantitative measurements of more than 300 individual species within 20 min. The method was applied to investigate cardiac- and neural-specific developmental changes in sphingolipid regulation from the postnatal stage to reproductive senescence in mice, revealing that endogenous lysobisphosphatidic acids and specific complex glycosphingolipids are tightly co-regulated to foster concerted reductions in sphingolipid levels at distinct stages of postnatal development. Our lipidomic data suggest that such changing regulatory patterns in sphingolipid homeostasis is attributed to differential endolysosomal degradation of complex sphingolipids, which may be critical in ensuring efficient sphingolipid catabolism and organismal health at each stage of postnatal development. PMID- 30292290 TI - A sensitive, high-throughput LC-MS/MS method for measuring catecholamines in low volume serum. AB - A robust, sensitive, high-throughput method for the detection and quantification of catecholamines in serum, including dopamine, 5-methoxytryptamine, tyramine, phenylethylamine (PEA), epinephrine (EPI), norepinephrine (NE), metanephrine (MN), and normetanephrine (NMN) is described. It is based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) in a positive scheduled multiple reaction monitoring (MRM) mode. Key to the success of the method is the inclusion of an amine derivatization step, using phenylisothiocyanate (PITC), prior to liquid chromatographic separation of the targeted analytes on a C18 reversed-phase column. Mass spectrometric conditions, e.g., characteristic fragmentations and quantification transitions were also optimized to obtain maximum sensitivity and specificity. The limits of detection for all the target analytes are in the low nanomolar range. The recovery rates of spiked serum samples with three different concentration levels, i.e., low, medium, and high, are in the range of 93.2%-113% with satisfactory precision values of less than 10.9%. This method was successfully applied to determine the concentrations of dopamine, 5-methoxytryptamine, tyramine, PEA, EPI, NE, MN, and NMN in multiple human serum samples, with results matching closely those reported in the literature. Comparisons to other reported methods for measuring catecholamines indicates this new approach requires 10-20X less volume, making it ideal for targeted metabolomics studies with volume-limited samples. The method has been adapted to a 96-well plate format and has allowed the quantitative determination of catecholamines in more than 800 serum samples on a single instrument in just nine days. PMID- 30292291 TI - Software-aided quality control of parallel reaction monitoring based quantitation of lipid mediators. AB - We characterized the performance of a micro-flow LC-ESI-MS2 approach to analyze lipid mediators (LMs) and polyunsaturated fatty acids (PUFA) that was optimized for SPE free lipid extraction. Tandem mass spectrometry was exclusively performed in parallel reaction monitoring (PRM) mode using TOF and Orbitrap analyzers. This acquisition strategy allowed in addition to quantitation by specific quantifier ions to perform spectrum comparisons using full MS2 spectra information of the analyte. Consequently, we developed a dedicated software SpeCS that allows to 1) process raw peak lists, 2) generate customized spectral libraries, 3) test specificity of quantifier ions and 4) perform spectrum comparisons. The dedicated scoring algorithm is based on signal matching and Spearman's rank correlation of intensities of matched signal. The algorithm was evaluated in respect of its specificity to distinguish structural related LMs on both instrument platforms. We show how high resolution mass spectrometry is beneficial to distinguish co eluted LM isomers and provide a generalized quality control procedure for PRM. The applicability of the approach was evaluated analyzing the lipid mediator response during M. tuberculosis infection in the mouse lung. PMID- 30292292 TI - Isotope-labeling derivatization with 3-nitrophenylhydrazine for LC/multiple reaction monitoring-mass-spectrometry-based quantitation of carnitines in dried blood spots. AB - Carnitines are diagnostic biomarkers of fatty acid oxidation defects and organic acidemias. Quantitative measurements of various carnitines in dried blood spot (DBS) have potential use in remote health applications for disease diagnosis and epidemiological surveillance. To provide an improved LC/multiple-reaction monitoring (MRM)-MS method for quantitation of carnitines in DBS, 3 nitrophenylhydrazine (3NPH) was tested as a high-efficiency chemical isotope labeling reagent for pre-analytical derivatization of 24 routinely-analyzed species. Reaction conditions were optimized and carnitine structural isomers were separated by reversed-phase LC with positive-ion MRM/MS detection, giving on column lower LOQs of sub- to low-femtomole levels. 13C6-3NPH was used to produce 13C6- or 13C12-labeled derivatives of the mono- and di-carboxylic carnitines in a "one-pot" reaction. These labeled analogues were used as stable isotope-labeled internal standards to compensate for possible ESI matrix effects. Combined with an optimized, two-step procedure for the extraction of carnitines from DBS, this isotope-labeling derivatizaiton - LC/MRM-MS method provided good linearity, high precision (intra-day CVs of <=7.8% and inter-day CVs of <=8.8%) and high accuracy (three levels of standard substances spiked in, with recoveries of 86.9%-109.7%) quantitation of carnitines in three sets of DBSs on cellulose or cotton filter paper. This method was then applied to determine the concentration changes of the analytes in the DBSs under two stability-testing regimes: 1) a one-time 4-h sunlight exposure and 2) a set of cycled temperature transitions (-20 degrees C for 2 days, 40 degrees C for 2 days, and back to -20 degrees C for 2 additional days). All of the carnitines showed good stabilities under the first testing condition. Under the second testing condition, free carnitine showed concentration increases of 9.3%-16.1%; acetyl carnitine, 3-OH butyryl carnitine, and malonyl carnitine showed concentration decreases of 12.2%-17.3%, 12.9%-17.1% and 10.7%-15.3%, respectively, and other 20 acyl carnitines showed concentration changes of <10% in three sets of DBSs on cellulose or cotton filter paper. These preliminary stability-testing results indicate a need to more systematically investigate the effects of various environmental conditions on the chemical stabilities of carnitines in DBS specimens if this sampling method is to be used in remote health applications. PMID- 30292293 TI - Targeted metabolomics in bladder cancer: From analytical methods development and validation towards application to clinical samples. AB - Bladder cancer constitutes the ninth most common cancer worldwide and, despite continuous development of new diagnostic approaches, the thirteenth leading cause of global cancer mortality. In our previous untargeted urine metabolomic investigation, seventeen metabolites were found to be statistically differentiating bladder cancer patients and healthy volunteers. Therefore, the main goal of this study was to develop and validate an analytical method for simultaneous quantitative determination of those metabolites using reversed phase high-performance liquid chromatography coupled with triple quadrupole mass spectrometry technique (RP-HPLC-QQQ/MS). Different chromatographic conditions, as well as various sample treatment procedures were tested in order to provide the best separation and the lowest limit of quantification (LOQ) values for studied compounds. The validation was performed according to the Food and Drug Administration guidelines (FDA). The limit of determination (LOD) and the LOQ values were in the range of 0.21-10.51 ng/ml and 0.69-35.02 ng/ml, respectively. The concentration range of compounds was developed between 2.5 and 12500 ng/ml. Only one compound (trimethyllysine) showed a significant matrix effect (61%) and consequently low process efficiency (64%). Overall, developed method presented recovery and precision values within the ranges proposed by FDA guidelines. The optimized and validated method was applied to urine samples obtained from 40 patients with bladder cancer and 40 healthy volunteers matched according to ones of the most important risk factors for developing urinary bladder tumors, e.i. age, gender and BMI. Afterwards, statistical analysis was provided by the use of Student's t-test or U-Mann Whitney test. The developed method was sensitive, selective and reproducible to be applied for the quantification of metabolites in the investigation of urine samples. As a consequence, ten out of previously chosen seventeen compounds, participating in different metabolites' pathways (gut floral metabolism, RNA degradation, purine metabolism, etc.), were found to be statistically significantly different in the urine concentration (p < 0.05) between cancer and control groups. PMID- 30292294 TI - Simultaneous determination of tryptophan and its 31 catabolites in mouse tissues by polarity switching UHPLC-SRM-MS. AB - Tryptophan (TRP) and its catabolites have attracted a lot of attention because of their clinical significance to human health. Recently, microbiome-gut-brain axis was found to have links to many diseases based on the imbalance of TRP catabolism. By using ultra-high performance liquid chromatography coupled to electrospray ionization triple quadrupole mass spectrometry, we present a rapid, robust and comprehensive method to determine 31 TRP catabolites covering three major pathways - kynurenic, serotonergic and bacterial degradation - within 5 min. Polarity switching was employed to analyze catabolites in both ionization modes simultaneously for greatly improved analytical throughput. The intra-day and inter-day precision were 0.5-15.8% and 1.5-16.7%, respectively. Accuracy was between 75.8 and 126.9%. The developed method was applied to study the tissue level of TRP catabolites in the liver, ileum, ileal contents, brain and plasma samples from 8 mice, and clear differences in the distribution of TRP catabolites were observed in different tissues. Ratios of key catabolites to TRP were used to evaluate the activities of specific enzyme and pathway in respective tissues. This method has potential in high throughput analysis of TRP catabolites in biological matrices, which can facilitate understanding the influence of TRP catabolites on microbiome-gut-brain axis and on human health. PMID- 30292296 TI - Assessment of chemical equivalence in herbal materials using chromatographic fingerprints by combination of three similarity indices and three-dimensional kernel density estimation. AB - An intuitive and practical way to control chemical equivalence of secondary metabolites in herbal materials based on chromatographic fingerprints deserves a thorough discussion, yet it is relatively unexplored. For the first time, we propose a mixture of three similarity indices, the congruence coefficient, the average of the peak area ratios, and the larger value between the maximum peak area ratio and the reciprocal of the minimum peak area ratio, to make up for the weak points of some widely used similarity indices and to evaluate the chemical equivalence of two fingerprints from various perspectives. The three similarity values are fed into a three-dimensional kernel density estimation to determine the quality of herbal materials. This estimation enables precise detection of anomalies in the absence of prior quality determination experience. Forty Atractylodes samples similar in appearance and indiscriminately used for medical purposes were used to demonstrate the effectiveness of the developed approach. After a reference sample was postulated, a quality assessment of the 40 samples was performed using the three similarity values and the estimated kernel density. The samples that were judged by the developed approach to be of good quality were compared with those chosen by the most popular approach using decision criterion of a single similarity index. The benefits of the proposed approach were evident in that the qualified samples had the composition ratio and individual concentrations of multi-components closer to those of the reference in general, and their inter-sample deviation was significantly smaller. PMID- 30292295 TI - Towards enhanced metabolomic data analysis of mass spectrometry image: Multivariate Curve Resolution and Machine Learning. AB - Large amounts of data are generally produced from mass spectrometry imaging (MSI) experiments in obtaining the molecular and spatial information of biological samples. Traditionally, MS images are constructed using manually selected ions, and it is very challenging to comprehensively analyze MSI results due to their large data sizes and highly complex data structures. To overcome these barriers, it is obligatory to develop advanced data analysis approaches to handle the increasingly large MSI data. In the current study, we focused on the method development of using Multivariate Curve Resolution (MCR) and Machine Learning (ML) approaches. We aimed to effectively extract the essential information present in the large and complex MSI data and enhance the metabolomic data analysis of biological tissues. Multivariate Curve Resolution-Alternating Least Squares (MCR-ALS) algorithm was used to obtain major patterns of spatial distribution and grouped metabolites with the same spatial distribution patterns. In addition, both supervised and unsupervised ML methods were established to analyze the MSI data. In the supervised ML approach, Random Forest method was selected, and the model was trained using the selected datasets based on the distribution pattern obtained from MCR-ALS analyses. In the unsupervised ML approach, both DBSCAN (Density-based Spatial Clustering of Applications with Noise) and CLARA (Clustering Large Applications) were applied to cluster the MSI datasets. It is worth noting that similar patterns of spatial distribution were discovered through MSI data analysis using MCR-ALS, supervised ML, and unsupervised ML. Our protocols of data analysis can be applied to process the data acquired using many other types of MSI techniques, and to extract the overall features present in MSI results that are intractable using traditional data analysis approaches. PMID- 30292297 TI - Application of ensemble deep neural network to metabolomics studies. AB - Deep neural network (DNN) is a useful machine learning approach, although its applicability to metabolomics studies has rarely been explored. Here we describe the development of an ensemble DNN (EDNN) algorithm and its applicability to metabolomics studies. As a model case, the developed EDNN approach was applied to metabolomics data of various fish species collected from Japan coastal and estuarine environments for evaluation of a regression performance compared with conventional DNN, random forest, and support vector machine algorithms. This study also revealed that the metabolic profiles of fish muscles were correlated with fish size (growth) in a species-dependent manner. The performance of EDNN regression for fish size based on metabolic profiles was superior to that of DNN, random forest, and support vector machine algorithms. The EDNN approach, therefore, should be helpful for analyses of regression and concerns pertaining to classification in metabolomics studies. PMID- 30292298 TI - A quantitative metabolomics study of bacterial metabolites in different domains. AB - Absolute metabolite concentrations are essential information for quantitative metabolomics studies, as concentrations are closely related to metabolic reactions, enzyme kinetics and other important biological activities. A well performed metabolites extraction procedure, a reliable detection method, and a robust quantitative approach are all critical factors for obtaining absolute metabolite concentrations. Here, we used a HPLC-MS/MS based platform to successfully develop a 13C-labeled quantitative metabolomics approach, and applied this novel method to quantify bacterial metabolite concentrations in three different domains (i.e., intracellularly, extracellularly and to the whole culture), with high accuracy for a model Escherichia coli bacteria. The bacterial culture was grown in universal 13C-labeled medium and the metabolites were extracted by 40/40/20/methanol/ACN/H2O with 0.1% formic acid. One hundred and twenty-five metabolites were initially screened and one hundred and six 13C metabolites were confidently detected from the model bacteria grown in 13C labeled medium. A subset of twenty-one metabolites was subsequently quantified using 12C-metabolite chemical standards to assist the calculation of 13C metabolite concentration. This rigorous 13C-labled quantitative method was then applied to characterize the metabolic profile changes in three domains of E. coli going through antibiotic treatment. Our results demonstrated that metabolites from all three domains can be used to significantly differentiate the ampicillin treatment group and control group (without ampicillin). In conclusion, our work demonstrated that the quantitative metabolomics approach can be used as a valuable tool to study bacterial metabolism in different domains and to understand their response to environmental perturbations. PMID- 30292299 TI - Free oxysterols and bile acids including conjugates - Simultaneous quantification in human plasma and cerebrospinal fluid by liquid chromatography-tandem mass spectrometry. AB - A liquid chromatography-electrospray ionization-tandem mass spectrometry (LC ESI(+)-MS/MS) assay was developed and qualified for analyzing 35 analytes of the cholesterol metabolism, including free cholesterol, 17 free, non-esterified oxysterols and 17 free and conjugated bile acids in plasma and cerebrospinal fluid. As internal standards, 25 commercially available stable deuterium-labeled analogs of the analytes were used. Pre-analytical investigations included stability tests of analyte concentrations affected by different anticoagulation additives: lithium heparin-, citrate-, EDTA-K3-stabilized plasma and serum, and the stability in EDTA whole blood at RT. This LC-ESI(+)-MS/MS method was successfully applied for the analysis of paired serum/cerebrospinal fluid samples of patients with and without blood-brain barrier disturbance, as well as of 100 plasma samples of a LIFE-Adult study sub-cohort. A fast and simple sample preparation including protein precipitation and on-line solid-phase extraction was developed. As little as 55 MUL of human plasma/serum or cerebrospinal fluid were needed for the analysis. It was possible to separate isomeric oxysterols and bile acids within 23 min using a C18 core-shell column. The assay is capable of quantifying in a linear range of 0.8-250 ng mL-1 for free hydroxycholesterols, 0.2-10 ng mL-1 for dihydroxycholesterols, 0.2-500 ng mL-1 for bile acids and 16 2000 MUg mL-1 for cholesterol with acceptable accuracy and precision. In cerebrospinal fluid one free oxysterols, five free and five conjugated bile acids could be quantified. No significant differences between patients with and without blood-brain barrier disturbance were obtained. In the LIFE-Adult sub-cohort two free oxysterols, four free and seven conjugated bile acids could be quantified in EDTA plasma. Men showed significantly higher concentrations of 26-OHC than women (p = 0.035). Furthermore, in women lower levels of cholic acid, glycocholic acid, glycodeoxycholic acid, chenodeoxycholic acid, glycochenodeoxycholic acid, glycoursodeoxycholic acid, glycolithocholic acid and higher levels of taurocholic acid, taurochenodeoxycholic acid, ursodeoxycholic acid/hyodeoxycholic acid were quantified. PMID- 30292300 TI - Exosomal lipids for classifying early and late stage non-small cell lung cancer. AB - Lung cancer is the leading cause of cancer deaths in the United States. Patients with early stage lung cancer have the best prognosis with surgical removal of the tumor, but the disease is often asymptomatic until advanced disease develops, and there are no effective blood-based screening methods for early detection of lung cancer in at-risk populations. We have explored the lipid profiles of blood plasma exosomes using ultra high-resolution Fourier transform mass spectrometry (UHR-FTMS) for early detection of the prevalent non-small cell lung cancers (NSCLC). Exosomes are nanovehicles released by various cells and tumor tissues to elicit important biofunctions such as immune modulation and tumor development. Plasma exosomal lipid profiles were acquired from 39 normal and 91 NSCLC subjects (44 early stage and 47 late stage). We have applied two multivariate statistical methods, Random Forest (RF) and Least Absolute Shrinkage and Selection Operator (LASSO) to classify the data. For the RF method, the Gini importance of the assigned lipids was calculated to select 16 lipids with top importance. Using the LASSO method, 7 features were selected based on a grouped LASSO penalty. The Area Under the Receiver Operating Characteristic curve for early and late stage cancer versus normal subjects using the selected lipid features was 0.85 and 0.88 for RF and 0.79 and 0.77 for LASSO, respectively. These results show the value of RF and LASSO for metabolomics data-based biomarker development, which provide robust an independent classifiers with sparse data sets. Application of LASSO and Random Forests identifies lipid features that successfully distinguish early stage lung cancer patient from healthy individuals. PMID- 30292301 TI - Utilizing ion mobility spectrometry and mass spectrometry for the analysis of polycyclic aromatic hydrocarbons, polychlorinated biphenyls, polybrominated diphenyl ethers and their metabolites. AB - Polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) are persistent environmental pollutants originating from incomplete combustion of organic materials and synthetic sources. PAHs, PCBs, and PBDEs have all been shown to have a significant effect on human health with correlations to cancer and other diseases. Therefore, measuring the presence of these xenobiotics in the environment and human body is imperative for assessing their health risks. To date, their analyses require both gas chromatography and liquid chromatography separations in conjunction with mass spectrometry measurements for detection of both the parent molecules and their hydroxylated metabolites, making their studies extremely time consuming. In this work, we characterized PAHs, PCBs, PBDEs and their hydroxylated metabolites using ion mobility spectrometry coupled with mass spectrometry (IMS-MS) and in combination with different ionization methods including electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI) and atmospheric pressure photoionization (APPI). The collision cross section and m/z trend lines derived from the IMS-MS analyses displayed distinct trends for each molecule type. Additionally, the rapid isomeric and molecular separations possible with IMS-MS showed great promise for quickly distinguishing the parent and metabolized PAH, PCB, and PDBE molecules in complex environmental and biological samples. PMID- 30292302 TI - Ratiometric quantitation of thiol metabolites using non-isotopic mass tags. AB - Ratiometric quantitation is used in mass spectrometry to account for variations in ionization efficiencies due to heterogenous sample matrixes. Isotopes are most commonly used to achieve ratiometric quantitation because of their ability to co elute chromatographically with each other and to have similar ionization efficiencies. In the work presented here, a new non-isotopic quantitative tagging approach is presented which allows chromatographic co-elution and similar ionization efficiencies. Using two variations of maleimide tags, t-butyl and cyclohexyl maleimide, thiols are quantified with a high degree of linearity up to five-fold concentration differences. Because these two tags have similar hydrophobcities, they elute simultaneously which allows them to be used for ratiometric quantitation. Beyond the five-fold linear range, signal compression is observed. This technique was able to quantify thiol changes in both in vitro pharmacological treatments as well as in vivo diabetic tissue. PMID- 30292303 TI - Recent advances in the applications of metabolomics in eye research. AB - Metabolomics, the identification and quantitation of metabolites in a system, have been applied to identify new biomarkers or elucidate disease mechanism. In this review, we discussed the application of metabolomics in several ocular diseases and recent developments in metabolomics regarding tear fluids analysis, data acquisition and processing. PMID- 30292304 TI - Supported liquid extraction coupled to gas chromatography-selective mass spectrometric scan modes for serum steroid profiling. AB - Although, steroid profiling is being applied in clinical and biochemical studies, improvement of the technique is still needed for accurate quantification of steroids in case of limited biological sample volumes. To improve analytical sensitivity and selectivity in comparison to that of conventional methods, a method that comprises supported liquid extraction (SLE) and gas chromatography mass spectrometry with a combination of selected-reaction and selected-ion monitoring modes (GC-SRM/SIM-MS) was developed. Here, this combination of SLE purification with GC-MS method was optimized with 37 different types of steroids and the results were compared to a solid-phase extraction (SPE) method. The devised assay led to an increase in extraction efficiency with the good chromatographic selectivity through a single extraction step. The limits of quantification of the serum steroids, ranged from 0.2 to 5 ng mL-1, except for cholesterol (0.2 MUg mL-1), and the correlation coefficients for calibration curves were higher than 0.99. The precision and accuracy were 1.4%-10.5% and 82.7%-115.3%, respectively. The overall recoveries of 30 steroids ranged from 62.1% to 104.3%, while that of 7 sterols was 44.7%-75.7%. Then, this validated method was applied to monitor the serum steroid levels of mice, which showed significant sex and age dependent metabolic patterns. This technique can be used to evaluate the metabolic changes occurring in animal models as well as in clinical patients. PMID- 30292305 TI - Serum or plasma, what is the difference? Investigations to facilitate the sample material selection decision making process for metabolomics studies and beyond. AB - In analytical chemistry serum as well as plasma are recommended as sample material of choice. However, blood processing for the generation of serum or plasma is rather different. Whether plasma or serum is the preferable sample material is still controversial discussed. We performed in paired samples three UHPLC-mass spectrometry-driven metabolomics studies. In study 1 metabolite profiles of serum vs plasma were compared. 46% out of 216 identified metabolites showed significant different levels (paired Wilcoxon signed-rank test, p < 0.05, FDR <0.01) with only three metabolites (methionine, C2:0- and C3:0-carnitine) showing lower levels in serum. In study 2 comparison of three different serum blood collection tubes revealed that coagulation and associated processes distinctly alter metabolite levels depending on the tube-specific clotting process. Most pronounced differences were found for the dipeptide phenylalanine phenylalanine (highest levels in silicate containing serum blood collection tubes). In study 3 possible adverse effects of platelets, which still remain in standard plasma even after correct processing, were investigated. No differences in a pattern of 216 metabolites were detected in the comparison of standard and platelet-free plasma (PFP). Our results give novel insights in fundamental differences between serum and plasma, thereby providing valuable information for analytical chemists for decision making to either use serum or plasma before starting complex and time-consuming analytical investigations. PMID- 30292306 TI - Recent advances in using mass spectrometry for mitochondrial metabolomics and lipidomics - A review. AB - Metabolomics and lipidomics generally targets a huge number of intermediate and end products of cellular metabolism in body fluids, tissues, and cells etc. At present, mass spectrometry (MS) based metabolic or lipid profiling of routine biological specimens including the whole cells, tissues, plasma, serum and urine etc., can cover hundreds of metabolites or lipid species in one analysis, which has qualified deep elucidation of global metabolic and lipid networks. Mitochondria are important intracellular organelles and many critical biochemical reactions occur here, they provide building block for new cells, control redox balance, participate in apoptosis and behave as a signalling platform. Evidence suggests high prevalence of mitochondrial dysfunction occurs in a variety of cancers and other diseases, thus there is an urgent demand for investigating and clarifying mitochondrial metabolic and lipid alterations induced by diseases. Nevertheless, mitochondria contribute a small fraction to cellular contents, profiling of whole cell is probably unsuitable for monitoring alterations in mitochondria. Therefore, metabolomics and lipidomics analyses specially for mitochondria are necessary to understand disturbed metabolic and lipid pathways induced by environment and diseases. However, methods for comprehensively profiling metabolites and lipids in mitochondria have been limited at present. This review summarizes the current states and progress of MS-based mitochondrial metabolomics and lipidomics study. Details of mitochondrial isolation procedure, analytical methods and their applications are described. The challenges and opportunities are also given. PMID- 30292307 TI - Comparison of modified Matyash method to conventional solvent systems for polar metabolite and lipid extractions. AB - In the last decade, metabolomics has experienced significant advances in the throughput and robustness of analytical methodologies. Yet the preparation of biofluids and low-mass tissue samples remains a laborious and potentially inconsistent manual process, and a significant bottleneck for high-throughput metabolomics. To address this, we have compared three different sample extraction solvent systems in three diverse sample types with the purpose of selecting an optimum protocol for subsequent automation of sample preparation. We have investigated and re-optimised the solvent ratios in the recently introduced methyl tert-butyl ether (MTBE)/methanol/water solvent system (here termed modified Matyash; 2.6/2.0/2.4, v/v/v) and compared it to the original Matyash method (10/3/2.5, v/v/v) and the conventional chloroform/methanol/water (stepwise Bligh and Dyer, 2.0/2.0/1.8, v/v/v) using two biofluids (human serum and urine) and one tissue (whole Daphnia magna). This is the first report of the use of the Matyash method for extracting metabolites from the US National Institutes of Health (NIH) model organism D. magna. Extracted samples were analysed by non targeted direct infusion mass spectrometry metabolomics or LC-MS metabolomics. Overall, the modified Matyash method yielded a higher number of peaks and putatively annotated metabolites compared to the original Matyash method (1-29% more peaks and 1-30% more metabolites) and the Bligh and Dyer method (4-20% more peaks and 1-41% more metabolites). Additionally the modified Matyash method was superior when considering metabolite intensities. The reproducibility of the modified Matyash method was higher than other methods (in 10 out of 12 datasets, compared to the original Matyash method; and in 8 out of 12 datasets, compared to the Bligh and Dyer method), based upon the observation of a lower mRSD of peak intensities. In conclusion, the modified Matyash method tended to provide a higher yield and reproducibility for most sample types in this study compared to two widely used methods. PMID- 30292308 TI - MetExpert: An expert system to enhance gas chromatography-mass spectrometry-based metabolite identifications. AB - Gas chromatography-mass spectrometry (GCMS) is an important analytical technique in metabolomics studies and has been routinely used for metabolite profiling of biological samples. Spectral matching to databases of authentic compounds are the preferred tools for metabolite identifications; however, the metabolic coverage of these databases is still limited compared to the number of known metabolites. Several computational tools have been developed to facilitate the interpretation of MS data but unfortunately most of them have limited applicability to GCMS based metabolite identification. In this paper, we introduce a computer-aided, metabolite expert system called MetExpert which emulates the metabolite identification ability of a human expert using orthogonal datasets including molecular formulas, retention indices, and EI-MS spectra to characterize the molecular structures. This system integrates four modules including in silico derivatization, metabolite-likeness evaluation, retention prediction, and substructure prediction. In silico derivatization increases the searchable chemical space for TMS-derivatized metabolites many of which are absent in molecular structure databases. Metabolite-likeness evaluations are an efficient approach to select metabolite-like molecules when querying large databases such as PubChem. An artificial neutral network then establishes the quantitative structure-retention relationships for the accurate prediction of RIs that further refines the candidate molecules. In addition, PLS-DA models establish quantitative structure-spectra relationships for the prediction of metabolite substructures. Finally, weighted scoring of three orthogonal evaluations increases the identification rates. MetExpert outperformed current state-of-the art methods such as MetFrag and CFM-ID for ranking the correct identifications. While spectral comparisons with chemical standards or de novo structural elucidations are necessary to validate the predictions, MetExpert provides an efficient and effective approach to prioritize the candidates. PMID- 30292309 TI - A global HILIC-MS approach to measure polar human cerebrospinal fluid metabolome: Exploring gender-associated variation in a cohort of elderly cognitively healthy subjects. AB - Cerebrospinal fluid (CSF) is a key body fluid that maintains the homeostasis in central nervous system (CNS). As a biofluid whose content reflects the brain metabolic activity, the CSF has been profiled in the context of neurological diseases to provide novel insights into the disease mechanisms. However, a global high-throughput approach to measure a broad diversity of polar metabolites present in CSF is lacking. Although still perceived as challenging and less reproducible, hydrophilic interaction liquid chromatography (HILIC) has recently evolved to offer the unprecedented coverage capacity of water-soluble metabolome. Here, we present a global HILIC high-resolution mass spectrometry-based (HRMS) approach that combines the profiling in acidic pH ESI (+) and basic pH ESI (-) mode to extend the coverage of CSF polar metabolome. This approach allowed us to annotate and measure a broad range of central carbon metabolites (implicated in glycolysis, TCA cycle, nucleotide, amino acid and fatty acid metabolism) in CSF collected from cognitively healthy elderly volunteers (n = 32), using a single extraction method. Metabolite annotation was achieved using the accurate mass, RT and MS/MS criteria, allowing for the characterization of 146 measurable metabolites. Exploration of characterized individual CSF profiles allowed for a discovery of intriguing gender-associated differences, with significantly higher acylcarnitine levels in men and higher taurine levels women. With this case study, we demonstrate the value of combined HILIC ESI +/- HRMS profiling to assess CSF metabolome in clinical research studies. PMID- 30292310 TI - The influence of culture media upon observed cell secretome metabolite profiles: The balance between cell viability and data interpretability. AB - The application of metabolomics to investigating the cell secretome has garnered popularity owing to the method's large-scale data output, biochemical insight, and prospects for novel target compound discovery. However, there are no standardized protocols for the use of cell growth media, a factor that can exert profound effects upon the detected metabolites, and thus in the interpretability of the resulting data. Herein, we applied a liquid chromatography-high resolution mass spectrometry-based metabolomics approach to examine the influence of 5 different media combinations upon the obtained secretome of two phenotypically different cell lines: human embryonic kidney cells (HEK293) and L6 rat muscle cells. These media combinations were, M1: Medium 199, M2: Medium 199 + 2% fetal bovine serum (FBS), M3: Dulbecco's Modified Eagle's Medium (DMEM), M4: DMEM + 2% FBS and M5: Krebs-Henseleit Modified Buffer (KHB). The effect of incubation (37 degrees C) vs. refrigeration (4 degrees C) on DMEM medium over a 24 h period was also investigated. Results were validated for a selected panel of 5 metabolites measured from an additional cell culture experiment. Metabolomics identified a total of 53 polar metabolites that exhibited differential patterns on a cell type and medium-specific basis. We observed that choice of media was the primary contributor to the secreted metabolite profile detected. The addition of FBS resulted in unique detected metabolites, compared to media-only controls (M199 and DMEM alone). Glutamine and pyroglutamate were more abundant in incubated relative to refrigerated DMEM medium. The overall metabolic pattern of the metabolites from the targeted approach matched with that exhibited across M1-M5 of the metabolomics experiment, and aided in further identifying the presence of compounds that were below the limit of detection in metabolomics. Based upon these findings, we highlight the following considerations in designing a cell secretome-based metabolite profiling experiment: (1) multiple media combinations (with and without FBS) should be tested for each cell line to be investigated; (2) cell-free media combinations should be plated separately, and incubated/treated in the same experimental conditions as the cells; and (3) a compromise between cell death and metabolite detection should be identified in order to avoid batch-specific contributions from FBS supplementation.

AB - The biological role of oxidized glycerophosphocholines (oxPCs) is a current topic of research importantly contributing to the understanding of health and disease. Global non-targeted metabolomics offers an interesting approach to expand current knowledge and link oxPCs to new biological functions. Although this strategy is successful, it also has some limitations which are clearly noticeable during the identification process. For this reason, clear rules related to the identification of each group of metabolites are needed. This work attempts to provide the reader with a guideline for the recognition and annotation of oxidation among phosphocholines (PCs). Using several chromatographic characteristics and spectral information from tandem mass spectrometry, rapid and reliable annotation of long and short chain oxPCs can be performed. Some of this knowledge has been implemented in the publicly available annotation tool 'CEU Mass Mediator' (CMM) for semi-automated assignment of oxidation. Additionally, this tool was supplemented with accurate monoisotopic masses of oxPCs, expanding current information in other databases. Moreover, the characterization of oxidization products of PC(16:0/20:4) known as PAPC has been performed, providing a list of accurate mass product ions and neutral losses.

AB - In order to profile the lipidome for untargeted lipidomics applications, analysis by ultra-high performance liquid chromatography - high resolution mass spectrometry (UHPLC-HRMS) typically requires the extraction of lipid content from sample matrices using matrix-specific conditions. The Folch, Bligh-Dyer, and Matyash extraction methods, while promising approaches, were originally tailored to specific matrices (brain tissue, fish muscle, and E. coli, respectively). Each of these methods have specific solvent ratios that must be adhered to achieve optimal extraction. Thus, the sample-to-solvent ratios for these methods should be optimized for the sample matrix of interest prior to employment. This study evaluated the appropriate sample-to-extraction solvent ratios for human plasma based lipidomics studies. An advantage of employing biphasic lipid extractions is the ability to investigate both the aqueous and organic layers for increased analyte coverage in untargeted studies. Therefore, this work also evaluated the multi-omic capability of each lipid extraction method for plasma in an effort to provide a workflow capable of increasing analyte coverage in a single extraction, thus providing a more complete understanding of complex biological systems. In plasma, a decrease in sample-to-solvent ratios from 1:4, 1:10, 1:20, to 1:100 (v/v) resulted in a gradual increase in the peak area of a diverse range of metabolite (aqueous layer) and lipid (organic layer) species for each extraction method up to the 1:20(v/v) sample-to-solvent ratio. The Bligh-Dyer and Folch methods yielded the highest peak areas at every plasma sample-to-solvent ratios for both metabolite and lipid species. Depending on the lipid class of interest, the Folch or Bligh-Dyer method is best suited for analysis of human plasma at a 1:20 (v/v) sample to total solvent ratio. PMID- 30292313 TI - Development of simultaneous targeted metabolite quantification and untargeted metabolomics strategy using dual-column liquid chromatography coupled with tandem mass spectrometry. AB - Targeted quantification and untargeted global profiling are the two mainstream approaches, a merging of which could provide enhanced analytical potential in metabolomics research. Here, a simultaneous targeted quantification and untargeted metabolomics (STQUM) strategy was developed for more efficient, accurate and comprehensive metabolomics research by using ultra-high-performance liquid chromatography coupled with high-resolution tandem mass spectrometry (UPLC HRMS/MS). First, we selected 110 cancer-related metabolites as targets and established a dual LC sequential separation method for simultaneous analysis of strong and weak polar metabolites. In order to achieve efficient acquisition for synchronous qualitative and quantitative analysis, high-resolution, data dependent parallel reaction monitoring (PRM) method and data-independent all ion fragmentation (AIF) method were established. Their performance in targeted confirmation and quantification, and untargeted analysis were systematically investigated and assessed. In total, 78 metabolites were confidently confirmed in positive ion mode in both PRM and AIF assays, in which 73 metabolites can be accurately quantified. In addition, simultaneously untargeted profiling of 4651 features of high reliability and validity were achieved. Both AIF and PRM methods revealed high confidence, sensitivity and accuracy. In the STQUM approach, another 15 metabolites could be accurately quantified in negative ion mode. The method offers a new perspective for merging the hypothesis-based targeted quantitative validation and untargeted biomarkers discovery in one run for improved analysis efficiency and integrity. PMID- 30292314 TI - Current and future perspectives of functional metabolomics in disease studies-A review. AB - Functional metabolomics is a new concept, which studies the functions of metabolites and related enzymes focused on metabolomics. It overcomes the shortcomings of traditional discovery metabolomics of mainly relying on literatures for biological interpretation. Functional metabolomics has many advantages. Firstly, the functional roles of metabolites and related metabolic enzymes are focused. Secondly, the in vivo and in vitro experiments are conducted to validate the metabolomics findings, therefore, increasing the reliability of metabolomics study and producing the new knowledge. Thirdly, functional metabolomics can be used by biologists to investigate functions of metabolites, and related genes and proteins. In this review, we summarize the analytical, biological and clinical platforms used in functional metabolomics studies. Recent progresses of functional metabolomics in cancer, metabolic diseases and biological phenotyping are reviewed, and future development is also predicted. Because of the tremendous advantages of functional metabolomics, it will have a bright future. PMID- 30292315 TI - Profiling of potential brassinosteroids in different tissues of rape flower by stable isotope labeling - liquid chromatography/mass spectrometry analysis. AB - Brassinosteroids (BRs) play crucial roles in a variety of physiological processes in plants. The full elucidation of the functions of RBs relies on sensitive detection and accurate measurement of BRs in plants. However, the identification and quantification of BRs are challenging due to their low abundance as well as poor ionization efficiencies during mass spectrometry-based analysis. Herein, we developed a highly sensitive and selective strategy for profiling potential BRs in plants by stable isotope labeling liquid chromatography multiple reaction monitoring scan mass spectrometry (SIL-LC-MRM-MS) analysis. In the strategy, we used a pair of stable isotope labeling reagents 4-phenylaminomethyl benzeneboronic acid (4-PAMBA) and d5-4-phenylaminomethyl-benzeneboronic acid (4 PAMBA-d5) that can react with C22-C23 cis-diol on BRs for profiling potential BRs in plant tissues. The 4-PAMBA and 4-PAMBA-d5 labeled BRs could generate two characteristic neutral loss under collision induced dissociation (CID), respectively, which is used to establish the MRM-based detection and screening. The precursor ions of BRs labeled with 4-PAMBA and 4-PAMBA-d5 were set according to the reported structures of BRs, and the corresponding product ions were predicted by subtracting the lost neutral loss. In this respect, corresponding precursor ions and product ions in MRM transitions are formed. The peak pairs with a fixed mass difference, similar retention times and intensities were assigned as potential BRs. Using the developed SIL-LC-MRM-MS strategy, we successfully found 13 potential BR in different tissues of rape flower. Taken together, the SIL-LC-MRM-MS analytical strategy is promising for profiling potential BRs as well as other compounds that have the same functional moiety from complex biological samples. PMID- 30292316 TI - Development of an LC-ESI(-)-MS/MS method for the simultaneous quantification of 35 isoprostanes and isofurans derived from the major n3- and n6-PUFAs. AB - Misregulation of oxidative and antioxidative processes in the organism - oxidative stress - contributes to the pathogenesis of different diseases, e.g. inflammatory or neurodegenerative diseases. Oxidative stress leads to autoxidation of polyunsaturated fatty acids giving rise to prostaglandin-like isoprostanes (IsoP) and isofurans (IsoF). On the one hand they could serve as biomarker of oxidative stress and on the other hand may act as lipid mediators, similarly as the enzymatically formed oxylipins. In the present paper we describe the development of an LC-ESI(-)-MS/MS method allowing the parallel quantification of 27 IsoP and 8 IsoF derived from 6 different PUFA (ALA, ARA, EPA, AdA, n6-DPA, DHA) within 12 min. The chromatographic separation was carried out on an RP-C18 column (2.1 * 150 mm, 1.8 MUm) yielding narrow peaks with an average width at half maximum of 3.3-4.2 s. Detection was carried out on a triple quadrupole mass spectrometer operating in selected reaction monitoring mode allowing the selective detection of regioisomers. The limit of detection ranged between 0.1 and 1 nM allowing in combination with solid phase extraction the detection of IsoP and IsoF at subnanomolar concentrations in biological samples. The method was validated for human plasma showing high accuracy and precision. Application of the approach on the investigation of oxidative stress in cultured cells indicated a distinct pattern of IsoP and IsoF in response to reactive oxygen species which warrants further investigation. The described method is not only the most comprehensive approach for the simultaneous quantification of IsoP and IsoF, but it was also integrated in a targeted metabolomics method (Ostermann et al. (2015) Anal Bioanal Chem) allowing the quantification of in total 164 oxylipins formed enzymatically and non-enzymatically within 30.5 min. PMID- 30292317 TI - Lipid metabolism in mouse embryonic fibroblast cells in response to autophagy induced by nutrient stress. AB - Autophagy is of great significance in maintaining cellular homeostasis. Aberrant autophagy has been reported to contribute to the disease aetiology of metabolic syndrome, especially several key lysosomal storage disorders. However, the molecular mechanisms and the correlation between autophagy and lipid metabolism remains unclear. This study was designed and aimed to reveal the alteration of lipid metabolism in response to the autophagy induced by nutrient stress to give new insights into the molecular mechanisms between autophagy and lipid metabolism. An online normal-phase/reversed-phase two-dimensional liquid chromatography-mass spectrometry (NP/RP 2D LC-MS) method was developed to perform the lipidomics analysis of Atg7-/- mouse embryonic fibroblast cells (MEFs) and wild-type MEFs under nutrient stress. 48 and 35 lipid species in wild-type and Atg7-/- MEFs respectively finally meet the screening criteria with p-value less than 0.05 and fold change more than 1.5 in response to nutrient stress. Their alterations indicated that autophagy participated lipid metabolism to generate energy and form autophagosomes with significantly increased free fatty acids and glycerophospholipids, which protected wild-type MEFs from serious damages and delayed cell death. However, in Atg7-/- MEFs, due to the inhibition of autophagy, lipids were continuously consumed and cells suffered from damages even death. These results illustrated the close relationship between autophagy and lipid metabolism comprehensively and revealed diverse lipid targets for the investigation of autophagy. PMID- 30292320 TI - Editorial. PMID- 30292318 TI - Lipidomics reveals a systemic energy deficient state that precedes neurotoxicity in neonatal monkeys after sevoflurane exposure. AB - Although numerous studies have raised public concerns regarding the safety of anesthetics including sevoflurane in children, the biochemical mechanisms leading to anesthetics-induced neurotoxicity remain elusive. Moreover, potential biomarker(s) for early detection of general anesthetics-induced brain injury are urgent for public health. We employed an enabling technology of shotgun lipidomics and analyzed nearly 20 classes and subclasses of lipids present in the blood serum of postnatal day (PND) 5 or 6 rhesus monkeys temporally collected after exposure to sevoflurane at a clinically relevant concentration or room-air as control. Lipidomics analysis revealed numerous significant anesthetic-induced changes of serum lipids and their metabolites as well as short chain acylcarnitines in the brain and cerebrospinal fluid after anesthetic exposure. These include decreased carnitine and acylcarnitines, unchanged triacylglycerol mass but accumulation of 16:0 and 18:1 fatty acyl chains in the triacylglycerol pool, losses of polyunsaturated fatty acids in both non-esterified fatty acid and phospholipid pools, and increased 4-hydroxynonenal content as early as 2 h after sevoflurane exposure. Importantly, the amounts of short chain acylcarnitines in the brain and cerebrospinal fluid were also significantly reduced after anesthetic exposure. We propose that this serum lipidomic profile can serve as indicative of neuronal damage. Our results reveal that sevoflurane exposure induces an energy deficient state in the brain evidenced by reduced free and acyl carnitine contents, as well as the presence of a pro-inflammatory state in the exposed animals, providing deep insights into the underlying mechanisms responsible for anesthetic-induced neurotoxicity. PMID- 30292319 TI - Development of a simple and efficient method of harvesting and lysing adherent mammalian cells for chemical isotope labeling LC-MS-based cellular metabolomics. AB - Chemical isotope labeling (CIL) liquid chromatography mass spectrometry (LC-MS) has a potential to become a very powerful platform for comprehensive and quantitative analysis of metabolites in cellular metabolomics. While CIL LC-MS with rationally designed reagents for labeling can provide much enhanced detection and quantification of metabolites, pre-analytical process such as cell harvest and cell lysis is also a critical step in the overall workflow for metabolomic analysis. In this study, we examined various combinations of cell harvest and cell lysis methods in order to develop a simple and efficient method for harvesting and lysing adherent mammalian cells tailored to CIL LC-MS-based cellular metabolomics. We evaluated and compared two cell harvest methods (physical scraping and trypsinization) and two cell lysis methods (glass-bead assisted lysis and freeze-thaw-cycle lysis). We used two types of commonly used mammalian cells, HeLa and MCF-7 cells, to cross-validate the findings. LC-UV quantification of the labeled metabolites after dansylation of cell extracts was used to compare the overall cell harvest and cell lysis efficiencies among different combination methods. It was found that scraping combined with freeze thaw-cycle lysis gave the highest total metabolite concentration. We also performed multivariate and univariate analyses of the amine/phenol submetabolome data generated from different preparations to investigate the impact of cell harvest and lysis methods on cellular metabolome profiles. Comparing to scraping, trypsinization caused more significant metabolome changes likely due to metabolite leakage and metabolite level changes. The cellular metabolomes obtained from the two lysis methods were found to be similar; however, freeze thaw-cycle lysis gave a higher lysis efficacy, compared to the glass bead method. We concluded that the combination of scraping and freeze-thaw-cycle was optimal for harvesting and lysing adherent mammalian cells for CIL LC-MS metabolomics. PMID- 30292321 TI - Histological investigations on the dura mater vascular system of mice. AB - The human dura mater encephali is a well innervated and vascularized membrane. Its vascular system plays a crucial role in disorders and pathological cases like dural hematoma, meningitis, and different headache types. To investigate these diseases mouse models are increasingly being used. However, the literature on the vascular system of the mouse dura mater is sparse and explicit studies concerned exclusively with its vasculature are lacking. Here we present a detailed light and scanning electron microscopic investigation of the supratentorial dura mater of the mouse species, with a focus on the largest part of it, the parietal dura mater. By utilizing different immunohistochemical and classical staining methods, a "cartography" of the vascular system was achieved. Additionally, the different blood vessel types with their mural cells were characterized. In contrast to humans, no arteries were found in the mouse parietal dura mater. Its supply is assured through frontolateral and occipital localized arteriolar branches. These arteriolar vessels exhibit in some specimens arteriolar anastomoses with one another. The venous blood is drained to the superior sagittal and transverse sinus through satellite venules accompanying the arterioles or through solitary venules. In all samples, large ruptured venules were identified in the frontolateral dural area. Scanning electron microscopy revealed that these vessels were ruptured on the dorsal side (skull bones-oriented side) of the dura. Our results contribute to the anatomical data on the mouse species and may set up a basis for fundamental investigation of disorders, for which the role of dural blood vessels is not yet clarified.

AB - INTRODUCTION: The genus Aspergillus contains more than 300 species, which are divided into closely related groups called sections. Molecular studies have revealed numerous cryptic species within different sections of this genus, which have different profiles of antifungal susceptibility and lack diagnostic morphological features. However, there are few studies on the prevalence and in vitro antifungal susceptibility of the cryptic species of this genus. The aim of this study was to investigate the distribution of Aspergillus spp. among clinical samples, and to study their in vitro susceptibility to different antifungal drugs. METHOD: Over a period of 2-years (2014-2015), a total of 379 strains of the genus Aspergillus were isolated. Most of the isolates were classified as respiratory colonizations; no cases of invasive aspergillosis were found. The strains were identified by MALDI-TOF mass spectrometry, and susceptibility testing was performed by the EUCAST reference procedure. RESULTS: Twenty species belonging to 8 sections were identified, being A. fumigatus the most prevalent (44.1%). The prevalence of cryptic species was 15.3%, with a clear predominance of A. tubingensis. Among the tested antifungal drugs, amphotericin B was the less active in vitro, followed by triazole drugs and echinocandins. The cryptic species had minimun inhibitory concentrations (MICs) higher than the corresponding type species. CONCLUSIONS: Accurate identification of the genus Aspergillus at the species level and in vitro antifungal susceptibility testing are necessary because, as it has been shown, some species of this genus may show resistance profiles against available antifungal drugs. PMID- 30292327 TI - The urban injury severity score (UISS) better predicts mortality following penetrating gunshot wounds (GSW). AB - BACKGROUND: The Injury Severity Score (ISS) and the New ISS (NISS) underscore injury severity after GSW. This study assesses the Urban ISS (UISS), which incorporates all injuries. METHODS: Complete trauma program registry (TPR) data and chart analyses were performed on 585 patients (pts) over 28 months. Factors analyzed included age, gender, ISS, NISS, UISS, time of admission, intent of injury, race, number GSW, weapon, and outcome. RESULTS: The 585 patients could be categorized within three groups. The first group included 98 pts with low ISS (1 2), no organ injuries, and early discharge; the second group included 47 patients with severe shock who died during operation; the third group of 442 pts were admitted after operation. All injury scores correlated (p < 0.001) with assault, number GSW, death, and length-of-stay (LOS). Death and LOS correlated closely with assault and the resultant number of GSW, best seen with UISS compared to ISS or NISS. Race and admission time did not correlate with death or LOS. CONCLUSIONS: UISS correlates better than ISS and NISS in victims of inner-city firearm injuries. PMID- 30292328 TI - Stop the Bleed Training empowers learners to act to prevent unnecessary hemorrhagic death. AB - BACKGROUND: Uncontrolled bleeding is a leading cause of preventable death from trauma. With the rise in mass casualty events, training of laypersons can be life saving. "Stop the Bleed" is a campaign to teach the public techniques of bleeding control. We believe that training in these techniques will increase participants' willingness and preparedness to intervene and increase knowledge of trauma/hemorrhage control. METHODS: We created a "Stop the Bleed" training program. School nurses, medical students, researchers, and community members participated in the program. Pre- and post-training questionnaires assessed participants' willingness/preparedness to intervene in a casualty event and knowledge of trauma/hemorrhage control. RESULTS: There was a significant change in attitudes after receiving training (p < 0.05). There was also an improvement in knowledge regarding bleeding control techniques. CONCLUSIONS: "Stop the Bleed" training empowers participants with the confidence and knowledge to aid others in preventable hemorrhagic death.

AB - The aim of this network meta-analysis is to assess the impact of strut thickness on clinical outcomes in patients who underwent percutaneous coronary intervention. We searched Medline/PubMed and performed a Bayesian network meta analysis to compare outcomes of patients who underwent percutaneous coronary intervention with drug-eluting stents (DES) of different strut thicknesses (ultrathin 60 to 80 MUm; thin 81 to 100 MUm; intermediate 101 to 120 MUm; thick >=120 MUm). Studies comparing DES with similar strut thickness, bare metal stents, and fully bioresorbable scaffolds were excluded. Odds ratios with credible intervals (OR [CrIs]) were generated with random-effects models to compare outcomes. Our primary end point was stent thrombosis (ST). We identified 69 RCTs including 80,885 patients (ultrathin group = 10,219; thin group = 36,575; intermediate group = 11,399; thick group = 22,692). Mean age was 64 +/- 11 years and 75% were male gender. When compared with thick-strut DES, ultrathin struts had significant less ST and myocardial infarction (OR 0.43 [CrI 0.27 to 0.68]; and OR 0.73 [CrI 0.62 to 0.92], respectively). Sensitivity analysis including only studies with permanent polymer DES gave similar results. Improvement in DES technology with thinner struts is associated with significant reduction in ST and myocardial infarction compared with thicker struts. PMID- 30292331 TI - Relation Between Lead Exposure and Trends in Blood Pressure in Children. AB - Obesity raises blood pressure (BP) in children and adults. Nevertheless, as obesity increased around the globe, population systolic and diastolic blood pressures were flat or fell. Examining children is insightful because pediatric trends are largely unconfounded by antihypertensive therapy. Decomposing BP into arterial types, large artery measures (pulse pressure) increased in concert with obesity while small artery measures (mean arterial pressure, [MAP]) decreased, suggesting small arteries are the locus of the countervailing temporal trends. Pediatric lead exposure decreased as pediatric obesity rose. Over the period of rising obesity, we examined the association between lead exposure and temporal trends in BP. We analyzed anthropometric, BP, and laboratory data on 8-17 year old children from the serial cross-sectional National Health and Nutrition Examination Surveys 1976 through 2008. Multivariable adjusted survey regression was used to examine temporal trends in blood pressure in relation to blood lead concentrations (N = 13,501). As obesity prevalence rose from 5.3% to 24.5%, age sex adjusted systolic BP was flat (-0.01 [95% confidence interval (CI) -0.06, 0.04] mm Hg/yr, p = 0.8), diastolic BP and MAP decreased (respectively -0.28 [ 0.32, -0.24] and -0.19 [CI -0.23, -0.15], both p<0.0001) while pulse pressure increased (0.28 [0.23, 0.32], p<0.001). Accounting for blood lead concentration attenuated the decreasing MAP trend by 67%. In conclusion, the contrary trends in pediatric BP during the rise of pediatric obesity may be substantially attributable to decreasing lead exposure acting on small resistance arteries. These results have implications for globally observed BP trends in youth and adults. Environmental policy altering lead levels may have long-lasting cardiovascular benefits. PMID- 30292332 TI - Comparison of Incidence, Predictors, and Outcomes of Early Infective Endocarditis after Transcatheter Aortic Valve Implantation Versus Surgical Aortic Valve Replacement in the United States. AB - Infective endocarditis (IE) of prosthetic or bioprosthetic heart valves is a serious complication associated with significant morbidity and mortality. Data on the incidence, risk factors, and outcomes of IE after transcatheter aortic valve implantation (TAVI) in the United States are limited. We used the 2013 to 2014 Nationwide Readmissions Databases to determine the incidence of early IE after TAVI and surgical aortic valve replacement (SAVR) in the US. Clinical characteristics, independent predictors, and outcomes of patients with IE post TAVI were examined. In 29,306 TAVI and 66,077 SAVR patients, the incidence rates of early IE were 1.7% (95% confidence interval [CI] 1.5% to 1.9%) and 2.5% (95% CI 2.3% to 2.9%) per person-year, respectively. In a propensity-matched cohort of 15,138 TAVI and 15,030 SAVR patients (weighted), there were no significant differences in the incidence rates of IE (1.7% [95% CI 1.4% to 2.0%] vs 1.9% [95% CI 1.6% to 2.2%] per person-year, log-rank p = 0.29) or in the median (interquartile range) time to IE (91 [48 to 146] vs 92 [61 to 214] days, p = 0.13). Staphylococcus (30.4%), Streptococcus (29.9%), and Enterococcus (20.5%) were the most common causative organisms of IE post-TAVI. Younger age, history of heart failure, need for permanent pacemaker placement, cardiac arrest, major bleeding, and sepsis during the index TAVI hospitalization were independently associated with an increased risk of IE. In-hospital mortality rate during readmission for IE was 15.6%. In conclusion, in a nationally representative cohort of TAVI patients in the US, the incidence rate of early IE was 1.7% per person-year. Age, co-morbid conditions, invasive procedures, and complications during the index hospitalization were associated with incident IE post-TAVI. PMID- 30292333 TI - Meta-Analysis of Carvedilol for the Prevention of Anthracycline-Induced Cardiotoxicity. AB - Anthracycline is a commonly prescribed antineoplastic agent. As a consequence of the growing number of cancer survivors, the incidence of anthracycline-induced cardiotoxicity is increasing. However, the optimal primary preventive strategy is lacking. Therefore, we conducted a meta-analysis of all randomized controlled trials to evaluate the efficacy of carvedilol for the primary prevention of anthracycline-induced cardiotoxicity. A comprehensive search of electronic databases was conducted. The primary and secondary outcomes were the occurrence of low left ventricular ejection fraction, and the absolute change in left ventricular ejection fraction (LVEF), respectively. We calculated the odds ratios for the primary outcome and the weighted mean differences for the secondary outcomes using a random-effects model. We included 8 randomized controlled trials (633 total patients). Our results showed significantly reduced rates of low LVEF favoring the carvedilol group (3.2% vs 5.8%; odds ratios: 0.42; 95% confidence interval: 0.18 to 0.99; p = 0.05). Furthermore, there were significantly smaller reductions in LVEF in carvedilol-treated patients than in placebo-treated patients (mean differences: 2.41%; 95% confidence interval: 0.01 to 4.81; p = 0.05). In conclusion, prophylactic administration of carvedilol in anthracycline treated cancer patients may reduce the early onset of left ventricular dysfunction compared with placebo. PMID- 30292334 TI - Clinical and Economic Outcomes of Ranolazine Versus Conventional Antianginals Users Among Veterans With Chronic Stable Angina Pectoris. AB - Real-world outcomes in patients with chronic stable angina treated with ranolazine and other antianginal medications as second- or third-line therapy are limited. In a historical cohort study of veterans with chronic stable angina, we compared time with coronary revascularization procedures, hospitalizations, and 1 year healthcare costs between new-users of ranolazine versus conventional antianginals (i.e., calcium channel blockers, beta blockers, or long-acting nitrates) as second- or third-line. Weighted regression models calculated adjusted hazard ratios (HR) at up to 8-year follow-up, and adjusted incremental costs in the first year. Weighted groups comprised 4,699 ranolazine users and 31,815 conventional antianginal users. Percutaneous coronary intervention (PCI) occurred more often in ranolazine users compared with conventional antianginal users (HR 1.16; 95% confidence intervals [CI] 1.08 to 1.25, p <0.001), and coronary artery bypass grafting occurred less often (HR 0.82; 95% CI 0.68 to 1.00, p <0.046). All-cause and atrial fibrillation (AF) hospitalizations were less common with ranolazine users compared with conventional users (all-cause: HR 0.94; 95% CI 0.90 to 0.99, p <0.010; AF:HR 0.74; 95% CI 0.67 to 0.82, p <0.001), and acute coronary syndrome was more common (HR 1.13; 95% CI 1.00 to 1.27, p <0.042). Adjusted 1-year costs were $24,517 in ranolazine users and $24,798 in conventional users (difference, $-280; 95% CI $-1,742 to $1,181, p = 0.71). In conclusion, ranolazine users had lower rates of coronary artery bypass grafting and all-cause and AF hospitalizations, but higher rates of percutaneous coronary intervention and hospitalizations due to acute coronary syndrome compared with conventional antianginal users. Healthcare costs were similar between ranolazine and conventional antianginal users. PMID- 30292335 TI - Effect of Gender and Genetic Mutations on Outcomes in Patients With Hypertrophic Cardiomyopathy. AB - Gender has been proposed to impact the phenotype and prognosis of hypertrophic cardiomyopathy (HC). Our aims were to study gender differences in the clinical presentation, phenotype, genotype, and outcome of HC. This retrospective single center cohort study included 1,007 patients with HC (62% male, 80% genotyped) evaluated between 1977 and 2017. Hazard ratios (HR) were calculated using multivariable Cox proportional hazard regression models. At first evaluation, female patients presented more often with symptoms (43% vs 35%, p = 0.01), were older than male patients (56 +/- 16 vs 49 +/- 15 years, p <0.001), and more frequently had hypertension (38% vs 27%, p <0.001), left ventricular outflow tract obstruction (37% vs 27%, p <0.001), and impaired left ventricular systolic (17% vs 11%, p = 0.01) and diastolic (77% vs 62%, p <0.001) function. Overall, the genetic yield was similar between genders (54% vs 51%, p = 0.4); however, in patients >=70 years, the genetic yield was less in women (15% vs 36%, p = 0.03). During 6.8-year follow-up (interquartile range 3.2 to 10.9), female gender was not independently associated with all-cause mortality (HR 1.25 [0.91 to 1.73]), cardiovascular mortality (HR 1.22 [0.83 to 1.79]), heart failure-related mortality (HR 1.77 [0.95 to 3.27]), or sudden cardiac death (SCD) and/or aborted SCD (HR 0.75 [0.44 to 1.30]). Interventions and nonfatal clinical events did not differ between the genders. In conclusion, female patients with HC present at a more advanced age with a different clinical, phenotypic, and genetic status. There is no independent association between female gender and all-cause mortality, cardiovascular mortality, heart failure-related mortality, or SCD.

AB - Anticoagulant therapy is an effective stroke prevention measurement for subjects with atrial fibrillation (AF) who are at high risk of ischemic stroke. However, it is reported that oral anticoagulants (OACs) are generally underused in clinical practice. A better awareness of current usage of anticoagulant therapy would enable prevention of stroke secondary to AF. Therefore, we determined the nationwide prevalence of AF and the frequency of OACs use among patients with ischemic stroke in China. Based on the China National Stroke Screening Survey, a representative nationwide sample of 1,252,703 adults over 40 years old during 2013 and 2014 was involved. Information on demographic data, diagnosis of stroke, behavioral risk factors, family history of stroke, related diseases, and medications was collected. The community-based survey data showed that 5,588 patients (12.0%) with ischemic stroke had previous, or newly diagnosed, AF. Therefore, more than 2.15 million ischemic stroke patients had AF in China. Among ischemic stroke patients with AF, the strongest risk factor was coronary heart disease (odds ratio = 2.53), whereas dyslipidemia accounted for the largest contribution (population-attributable risk proportion = 17.33%). Of ischemic stroke patients with AF, only 2.2% had taken OACs; of them, 98.2% had taken warfarin. In conclusion, a large number of ischemic stroke patients with AF are significantly undertreated with OACs in China. This highlights the need for improvement of prevention of ischemic stroke secondary to AF. PMID- 30292337 TI - Contrast-Induced Nephropathy After Percutaneous Coronary Intervention for Chronic Total Occlusion Versus Non-Occlusive Coronary Artery Disease. AB - Contrast volume is associated with the incidence of contrast-induced nephropathy (CIN), and CIN risk could be particularly high in chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Our aim was to evaluate the incidence of CIN in patients who underwent CTO versus non-CTO PCI. All PCIs performed at our institution from January 2012 to December 2016 were included in this study. CIN was defined as an increase of >=0.3 mg/dl or >=50% from baseline within 72 hours. Multivariable logistic regression analysis was performed to identify independent predictors of CIN. A total of 2,580 patients were included (n = 309 CTO PCI and n = 2271 non-CTO PCI). Estimated glomerular filtration rate was lower in the non-CTO group (73.9 +/- 27.3 vs 77.1 +/- 24.7 ml/min/1.73/m2, p = 0.05). Patients in the non-CTO PCI group presented more often with acute coronary syndrome (47% vs 15%, p < 0.001). Contrast volume (347 +/- 159 vs 215 +/- 107 ml, p < 0.001) and contrast-volume-to-creatinine-clearance ratio (4.7 +/- 2.1 vs 3.2 +/- 1.8, p < 0.001) were higher in the CTO group. There was no difference in CIN rates between CTO and non-CTO groups (9.4% vs 12.1%, p = 0.17). This was confirmed in a sensitivity analysis including only patients who underwent PCI in a stable clinical setting (7.7% vs 8.5%, p = 0.66). On multivariate analysis hypotension during/before PCI (odds ratio [OR] 2.86), acute coronary syndrome (OR 1.86), age (OR 1.54), female sex (OR 1.51), left ventricular ejection fraction (OR 0.64), diabetes mellitus (OR 1.49), and contrast volume (OR 1.17) were independent predictors of CIN, while CTO PCI was not. In conclusion, CTO PCI is associated with similar rates of CIN, compared with non-CTO PCI. These findings persisted on sensitivity and multivariable analyses.

PMID- 30292339 TI - Meta-analysis on the Association Between Norepinephrine Transporter Gene rs2242446, rs5569 Polymorphisms and Risk of Major Depressive Disorder. AB - BACKGROUND AND AIMS: The association between norepinephrine transporter (NET) gene polymorphisms and the risk of major depressive disorder (MDD) has been investigated extensively, but with contradictory findings. MATERIALS/METHODS: To clarify such contradiction, a comprehensive meta-analysis was conducted by searching PubMed, EMBASE, Web of Science and China Knowledge Resource Integrated Database. Odd ratios (ORs) and 95% confidence intervals (Cis) were used to evaluate the strength of the association. RESULTS: Totally 23 case-control studies regarding rs2242446 and rs5569 polymorphisms were included. Overall analysis and subgroup analysis indicated no significant association between NET gene rs2242446 polymorphism and MDD risk. However, recessive and homozygous models revealed a significant association between NET rs5569 polymorphism and increased risk of MDD. The stratified analysis further indicated significant associations in Asians, hospital-based studies and studies with other genotyping methods. CONCLUSIONS: In conclusion, NET gene rs5569 polymorphism could increase the risk of MDD, especially among Asians.

AB - During space missions, real-time monitoring of astronauts' health status is of crucial importance and therefore there is a strong demand for simple analytical devices that astronauts can use to perform clinical chemistry analyses directly onboard. As part of the "IN SITU Bioanalysis" project, we designed a biosensor for analysing salivary levels of cortisol in astronauts, a marker of chronic stress. The biosensor is based on the Lateral Flow Immunoassay (LFIA) approach coupled with chemiluminescence (CL) detection and c o m p r i s e s a 3D-printed plastic cartridge containing a sealed fluidic element with the LFIA strip, in which the flow of sample and reagents i s activated by pressing buttons on the cartridge and sustained by exploiting capillary forces. For measurement, the photon emission i s imaged employing a CL reader based on an ultrasensitive cooled charge-coupled device (CCD) camera. The payload was designed to operate in microgravity and to withstand mechanical stress, such as take-off vibrations, and onboard depressurization events, while the microfluidics was developed considering alterations of physical phenomena occurring in microgravity, such as bubble formation, surface wettability and liquid evaporation. The biosensor, which was successfully used by the Italian astronaut Paolo Nespoli during the VITA mission (July-December 2017), demonstrated the feasibility of performing sensitive LFIA analysis of salivary cortisol down to 0.4 ng/mL directly onboard the International Space Station. It could be easily adapted for the analysis of other clinical biomarkers, thus enabling the early diagnosis of diseases and the timely activation of appropriate countermeasures.

PMID- 30292346 TI - Attention and awareness: Representation of visuomotor space in split-brain patients. AB - Each cerebral hemisphere primarily controls and receives sensory input with regard to the contralateral hand. In the disconnected brain (split-brain), when the hands are uncrossed, direct visual access to each hand is available to the controlling (contralateral) hemisphere. However, when a hand crosses the midline, visual and tactile information regarding the hand are presented to different hemispheres. It is unknown how a contralateral hemisphere codes the position and orientation of a visually inaccessible hand in the disconnected brain. The present work addresses this issue. We ask how each hemisphere represents "its" hand across hand positions that span the midline in the absence of cortical input from the contralateral hemisphere. In other words, when a hand is placed across the midline and is visually inaccessible, is it represented by the controlling hemisphere: (1) in accordance with its new position with respect to the body (e.g., a left hand "becomes" a right effector when it crosses the midline), (2) with left/right position information unaltered (e.g., the left hand is represented as "left" regardless of its location), or (3) stripped of its location information altogether? The relationship between hand position and the spatial codes assigned to potential responses (an index of hand representation) was investigated in two split-brain patients using direct (Experiment 1) and orthogonal (Experiment 2) S-R compatibility paradigms. S-R compatibility effects in split-brain patients were consistent with those displayed by typical individuals. These findings suggest that position-based compatibility effects do not rely on cross-cortical connections. Rather, each hemisphere can accurately represent the full visuomotor space, a process that appears to be subserved by subcortical connections between the hemispheres.

AB - Circulating tumor-reactive immune cells link tumor responses at anatomically distant locations, yet this interconnectedness is poorly understood on a macro level. Can we use mathematical models to better understand these complex relationships? Recent work provides a framework to evaluate the effects that T cells generated at one site may have on metastases elsewhere in the body and suggests that in the era of immunotherapy the concept of 'local' therapy needs to be refined. PMID- 30292348 TI - Lighting Up Cancer Dynamics. AB - Live-cell microscopy has revealed that signaling pathways carry elaborate time varying activities. Yet, the connection between these dynamics and cellular disease has remained elusive. Recent work leverages cellular optogenetics to analyze the Ras-to-Erk transfer function in cancer cells. These analyses reveal how changes to the filtering properties of a pathway lead to the misperception of extracellular events. Overall, these studies suggest that mutations do not simply hyperactivate pathways but rather can also change their transmission properties in more subtle ways. PMID- 30292349 TI - Mutation Signatures Depend on Epigenomic Contexts. AB - Mutation signatures - the patterns of acquired genetic changes in somatic genomes - provide critical insights into DNA repair defects and exposure to mutagenic processes during development, aging, and cancer progression. Efforts to decipher the etiology of the emerging computationally predicted mutation signatures in cancer genomes are currently underway. Since chromatin and epigenomic contexts influence DNA damage and repair pathway choices, taking both epigenomic and sequence contexts of the mutations into consideration is likely to benefit interpretation of mutation signatures. PMID- 30292350 TI - Are Microbial Endophytes the 'Actual' Producers of Bioactive Antitumor Agents? AB - For millenia, plants have been a major source of medications against human and animal diseases. In the case of anticancer agents, a significant number of current agents can trace their source back to nominally plant secondary metabolites, with examples being taxol, vinca alkaloids, camptothecin (CPT), and their modified derivatives. However, it is now becoming apparent that these and other plant-derived materials, plus similar agents from marine sources may well have a microbe in their background. In this short Opinion, evidence for such claims are presented for some of the agents currently in use or in preclinical and clinical trials against cancer. PMID- 30292351 TI - Synthetic Lethality and Cancer - Penetrance as the Major Barrier. AB - Synthetic lethality has long been proposed as an approach for targeting genetic defects in tumours. Despite a decade of screening efforts, relatively few robust synthetic lethal targets have been identified. Improved genetic perturbation techniques, including CRISPR/Cas9 gene editing, have resulted in renewed enthusiasm for searching for synthetic lethal effects in cancer. An implicit assumption behind this enthusiasm is that the lack of reproducibly identified targets can be attributed to limitations of RNAi technologies. We argue here that a bigger hurdle is that most synthetic lethal interactions (SLIs) are not highly penetrant, in other words they are not robust to the extensive molecular heterogeneity seen in tumours. We outline strategies for identifying and prioritising SLIs that are most likely to be highly penetrant. PMID- 30292352 TI - Trinucleotide Repeat Expansion Diseases, RNAi, and Cancer. AB - Many neurodegenerative diseases are caused by unstable trinucleotide repeat (TNR) expansions located in disease-associated genes. siRNAs based on CAG repeat expansions effectively kill cancer cell lines in vitro through RNAi. They also cause significant reduction in tumor growth in a human ovarian cancer mouse model with no toxicity to the treated mice. This suggests that cancer cells are particularly sensitive to CAG TNR-derived siRNAs, and explains a reported inverse correlation between the length of CAG TNRs and reduced global cancer incidences in some CAG TNR diseases. This review discusses both mutant proteins and mutant RNAs as a cause of TNR diseases, with a focus on RNAi and its role in contributing to disease pathology and in suppressing cancer. PMID- 30292353 TI - Emerging Contributions of Cancer/Testis Antigens to Neoplastic Behaviors. AB - Tumors of nearly every origin activate the expression of genes normally restricted to gametogenic cells. These genes encode proteins termed cancer/testis (CT) antigens, since expression outside of their naturally immune-privileged site can evoke an immune response. Despite extensive efforts to exploit CT antigens as immunotherapeutic targets, investigation of whether these proteins participate in tumorigenic processes has lagged. Here, we discuss emerging evidence that demonstrates that CT antigens can confer a selective advantage to tumor cells by promoting oncogenic processes or permitting evasion of tumor-suppressive mechanisms. These advances indicate the inherent flexibility of tumor cell regulatory networks to engage aberrantly expressed proteins to promote neoplastic behaviors, which could ultimately present novel therapeutic entry points.

PMID- 30292355 TI - Optimization of sample preparation procedures for evaluation of the mineral composition of fish feeds using ICP-based methods. AB - This work describes the application of an experimental design in optimizing the decomposition and spectrometer operational conditions for analysis of fish feeds. The content of 22 elements (six macroelements, four microelements and eleven trace elements) in feeds for fishes (ornamental and for human consumption) was determined by inductively coupled plasma (ICP)-based methods. Limits of quantification were obtained and the values ranged between 0.02 mg kg-1 (Cd) and 76 mg kg-1 (Al). Evaluation of the methods was achieved through analysis of standard reference material, Oyster Tissue (NIST 1566b) and Tea (NCS DC 73351). Element concentrations in feed samples for ornamental fish ranged from <0.02 mg kg-1 (Cd) to 2.79% (P) and for fish breeding for human consumption from <0.02 mg kg-1 (Cd) to 2.00% (Ca). The concentrations of the elements obtained in the analyzed fish feeds were within the limits established by Brazilian and American legislation for regulated elements.

AB - A method using reversed-phase high-performance liquid chromatography with diode array detection (HPLC-DAD) was applied after extraction with acidified methanol, to determine 12 bioactive phenolic compounds in the peel and pulp of the mango fruit (Mangifera indica L.) cultivated in the Bahia, state of Brazil. The proposed methodology was previously fully validated and proven successful in the analysis of methanolic extracts of lyophilized samples. The limits of quantification ranged between 0.78 and 3.14 mg L-1 and the individual recovery values obtained for the spiked samples ranged from 80% to 120%. The results were evaluated using PCA and ANN. The results indicate that the fruits are rich in polyphenols, mainly: ellagic acid, gallic acid, rutin and catechin, which contribute to their greater use as functional foods, natural antioxidants and in the pharmaceutical industry, as well as other applications. PMID- 30292357 TI - Evaluation of olive oils from the Mediterranean region by UV-Vis spectroscopy and Independent Component Analysis. AB - Extra-virgin olive oil (EVOO) from Mediterranean were analyzed by Ultraviolet Visible (UV-Vis) spectroscopy and Independent Component Analysis (ICA). The use of ICA resolution provided information over dienes (primary oxidation compound), polyphenolic compounds, tocopherol, carotenoids and chlorophylls when EVOO was evaluated by UV-Vis spectroscopy. Based on these data, ICA could be used to determine the contribution of chemical compounds to the composition of EVOO produced in different regions from Mediterranean. The results suggest that the combination of UV-Vis measurements and ICA makes possible the EVOO evaluation, and can contribute to suggesting that a foodstuff comes from an alleged origin. The proposed methodology is a low cost, fast and sample preparation free methodology to highlights the EVOO characteristics produced in the Mediterranean region.

AB - A procedure using ICP OES for sample preparation for the determination of copper, iron and manganese in cashew nuts was developed. Constrained simplex-centroid design was applied in the optimization of the digestion in microwave oven procedure, and the results evaluated from topological maps of the Kohonen network. The best proportion evaluated for the digestion of the sample with HNO3, H2O2 and H2O was 10:45:45 (%). With optimized conditions, the detection limits were 0.63, 4.3 and 0.37 mg kg-1, and quantification 2.1, 14 and 1.2 mg kg-1 for Cu, Fe and Mg, respectively. The precision (% RSD) was 1.84, 2.31 and 2.73, for Cu, Fe and Mg, respectively. The procedure proposed had the accuracy confirmed using NIST 1568b (at 95% reliability) and was applied in the samples obtaining concentrations in the range of 10.7-19.4, 44.3-67.2 and 11.0-21.4 mg kg-1 for Cu, Fe and Mg, respectively. PMID- 30292360 TI - Discrimination between conventional and omega-3 fatty acids enriched eggs by FT Raman spectroscopy and chemometric tools. AB - This work developed an analytical method to differentiate conventional and omega 3 fat acids enriched eggs by Raman spectroscopy and multivariate supervised classification with Partial Least Squares Discriminant Analysis (PLS-DA). Forty samples of enriched eggs and forty samples of different types of common eggs from different batches were used to build the model. Firstly, gas chromatography was employed to analyze fatty acid profiles in egg samples. Raman spectra of the yolk extracts were recorded in the range from 3100 to 990 cm-1. PLS-DA model was able to correctly classify samples with nearly 100% success rate. This model was validated estimating appropriate figures of merit. Predictions uncertainties were also estimated by bootstrap resampling. The most discriminant Raman modes were identified based on VIP (variables importance in projection) scores. This method has potential to assist food industries and regulatory agencies for food quality control, allowing detecting frauds and enabling faster and reliable analyzes.

AB - The elemental/centesimal composition of dried fruits and capsules containing Goji berries (Lycium barbarum L.) was evaluated by ICP OES after two digestion procedures. Furthermore, phenolic acid compounds and flavonoids were quantified by HPLC-UV-DAD. Precision, accuracy, LOD and LOQ were evaluated. The samples showed similar contents of proteins, lipids and carbohydrates. The metal contents in the samples were found at different levels (minimum-maximum, in mg kg-1), as follows: Ca (181.1-200.2); Cu (1.703-2.145); Fe (7.420-7.852); K (81.78-83.59); Mg (92.58-95.12); Mn (1.630-2.570); Na (587.9-590.7); P (3.124-3.360); Se (2.812 3.345); V (0.055-0.062) and Zn (2.325-2.610). Al, As, Ba Cd, Co, Ni, P, Pb, Sb, Sn and Sr showed values below the LOD. Accuracy was assessed by analysis of tomato leaves (NIST 1573a). Eight bioactive phenolic compounds (caffeic, chlorogenic, ellagic, ferulic, gallic, p-coumaric, syringic and vanillic acids) and two flavonoids [(+)-catequin and rutin] were determined, in levels of 55.5 83.700 and 172.3-2982.4 mg kg-1, respectively.

AB - Statistical mixture design extraction and fractionation of Mikania plant samples were carried out to quantitatively study seasonal and solvent composition effects as well as their interactions on secondary metabolites. The mixture design consisted of ethanol, acetone, dichloromethane and chloroform solvents and their binary, ternary and quaternary mixtures. Yields were measured for the crude extract and its neutral, organic, basic, polar and fiber fractions obtained with each solvent composition from samples harvested during 2010. Two-way ANOVA found statistically significant seasonal and solvent effects for the crude extract and all the fractions except for the polar fraction solvent. The best solvent extractor depends the harvest season. High crude, organic and polar fraction yields in the summer are correlated with the coumarin UV-vis absorbance at 274 nm. Crude yields of mixtures containing ethanol are correlated with the coumarin absorbances in summer, winter and spring whereas mixtures without ethanol show no significant correlation.

AB - A microwave-assisted digestion procedure using diluted HNO3 and H2O2 was developed for multi-element determination in guarana samples by ICP OES. Optimization step was performed employing a mixture design with pseudocomponents using HNO3, H2O2 and H2O. The analytical signal of each element, residual acidity and residual carbon content were optimized simultaneously using the desirability function. The best condition for digestion of a 250 mg sample mass resulted from a mixture constituted by 1.0 mL of HNO3, 3.0 mL of H2O2 and 6.0 mL of H2O. This condition allowed final digests with residual acidity and residual carbon content of 0.4 mol L-1 and 6.5%, respectively. The method was validated and applied for the determination of K, Ca, Mg, S, P, Cu, Fe, Mn and Zn in 72 guarana seed samples from Bahia state.

AB - Sweet potato is a food consumed in the world. In this work, the minerals and centesimal composition in sweet potatoes of organic and conventional cultivars was investigated. The accuracy was confirmed with a certified reference material of apple leaves (NIST 1515). The quantification of the samples was performed by inductively coupled plasma optical emission spectrometry and the digestion efficiency was evaluated by residual carbon content. The mean concentrations (in mg/100 g) of minerals were: 23.5 and 40.7 (Ca); 0.082 and 0.159 (Cu); 0.303 and 0.481 (Fe); 197 and 381 (K); 166 and 35.7 (Mg); 0.183 and 1.15 (Mn); 68.6 and 0.433 (Na); 54.1 and 62.2 (P) and 0.197 and 0.261 (Zn) for conventional and organic cultivars, respectively. Average centesimal concentrations in conventional and organic cultivars (in %), were: 72 and 72 (moisture); 0.87 and 0.90 (ashes); 1.5 and 1.4 (proteins); 0.63 and 0.54 (lipids) and 24.8 and 23.9 (carbohydrates).

AB - This work evaluated the influence of the cooking methods (cooked in a water bath, in a stove, and in a microwave oven) on the mineral composition of mustard leaves (Sinapis alba). So, raw and cooked samples were digested and afterward the elements calcium, magnesium, potassium, sodium, iron, zinc, phosphor, barium and sulfur were determined using inductively coupled plasma optical emission spectrometry (ICP OES). The experimental work involved a set of five samples from different locations, processed in triplicates. The results were evaluated employing Principal Component Analysis (PCA), Hierarchical Cluster Analysis (HCA) and Linear Discriminate Analysis (LDA). All techniques showed that the mineral content of the raw and cooked samples in a water bath is different from the samples cooked in stove and microwave oven. Especially for potassium, whose content is strictly controlled for chronic renal patients, this study showed that cooking using microwave oven has the greatest efficiency for reduction. PMID- 30292366 TI - Attenuated Total Reflectance Fourier Transform Spectroscopy (ATR-FTIR) and chemometrics for discrimination of espresso coffees with different sensory characteristics. AB - Coffee cup quality, determined by the sensory attributes evaluated by professional tasters, is a decisive factor for evaluating coffee, with the "Specialty Coffee Association of America" (SCAA) classification being nowadays considered the most suitable. Panels of trained coffee tasters are used by the industry to describe and evaluate beverage quality, but those evaluations can be subjective and time demanding. Recent studies have demonstrated the potential of spectroscopy-based methods for establishing parameters of quality in the analysis of food products, including coffee. Thus, the aim of this study was to evaluate the potential of ATR-FTIR and chemometrics to discriminate espresso coffees with different sensory characteristics reported by a panel of coffee tasters. The results showed good consistency among coffee tasters. PLS-DA models based on spectroscopic data were able to classify samples according to sensory attributes, confirming the potential of FTIR and chemometrics in coffee quality evaluation.

Multivariate designs were performed to evaluate the variables and optimize the best condition of chemical vapor generation (CVG) and simultaneous determination of mercury and selenium by AFS. Fish samples were prepared via acid digestion in digester block with cold finger reflux system, which ensured that the elements were not lost by volatility. The proposed analytical method was validated, and excellent figures of merit have been achieved, such as detection limits of 0.33 and 9.18 ng g-1 for mercury and selenium, respectively. The method was applied for simultaneous determination of mercury and selenium in canned sardines. Mercury concentrations ranged from 0.057 to 0.203 MUg g-1 and selenium concentration from 1.76 to 2.21 MUg g-1, providing a mean molar ratio (Se:Hg) equivalent to 36.

AB - This work presents a simple and low-cost analytical approach to detect adulterations in ground roasted coffee by using voltammetry and chemometrics. The voltammogram of a coffee extract (prepared as simulating a home-made coffee cup) obtained with a single working electrode is submitted to pattern recognition analysis preceded by variable selection to detect the addition of coffee husks and sticks (adulterated/unadulterated), or evaluate the shelf-life condition (expired/unexpired). Two pattern recognition methods were tested: linear discriminant analysis (LDA) with variable selection by successive projections algorithm (SPA), or genetic algorithm (GA); and partial least squares discriminant analysis (PLS-DA). Both LDA models presented satisfactory results. The voltammograms were also evaluated for the quantitative determination of the percentage of impurities in ground roasted coffees. PLS and multivariate linear regression (MLR) preceded by variable selection with SPA or GA were evaluated. An excellent predictive power (RMSEP = 0.05%) was obtained with MLR aided by GA.

Six phenolic acids (Gallic, trans-cinnamic, caffeic, ferulic and p-coumaric acids) and two methylxanthines (caffeine, theobromine) were studied, according to the principles of green chemistry, with the goal of comparing teas with different processing level. After development and validation of separation and extraction methods was applied to 11 extracts obtained by infusions of green and black tea samples in commercial areas of the city of Salvador-BA, showing feasible and efficient. Was employed multivariate data analysis and the Tukey test to correlate the chromatographic profile with the different samples. Principal component and analysis and hierarchical cluster analysis were used for the chromatographic analysis, allowing the visualization of two groups, formed by green and black tea samples.

Carbonyl compounds were analyzed by High Performance Liquid Chromatography (HPLC-UV), BTEX (Benzene, Toluene, Ethylbenzene and Xylenes) by gas chromatoghaphy (GC-FID), and trace elements by inductively coupled plasma optical emission spectrometry (ICP-OES). Seven carbonyl compounds were quantified including acrolein (<3-115 ug L-1), which is considered a potent mutagenic agent, above the potability limit in 75% of the cases. Trace elements such as copper, zinc, barium, aluminum and lead, more frequently found, were also quantified, and lead (<0,56-99 ug L-1) was above the tolerable limit for drinking water of 10 MUg L-1 in 73% of the cases. The results show that the stored water in polyethylene cisterns in the Brazilian semiarid region does not present satisfactory conditions for human consumption.

AB - Thermal rice oil degradation was evaluated by UV-Vis and NIR in three-way arrays assembled with samples, different temperatures, and the absorbance at different wavelengths by applying PARAFAC chemometric method. The loadings matrix of the mode corresponding to the samples (scores) contains the information related to the samples. The loadings on the temperature mode resemble kinetics profiles. These profiles change with the nature of the component responsible for the factor and evolve with the heating temperature. The loadings on the spectral mode reveal the antioxidants gamma-oryzanol and tocopherol, and oxidation products are the components responsible for the two factors. The results achieved showed that the antioxidants concentration decreases starting at 70 degrees C while oxidation products start to increase more pronounced after 90 degrees C. The proposed method is shown to be a simple and fast way to obtain information about the oxidative stability of rice oils.

AB - The fractional factorial and Doehlert designs for optimization of a slurry sampling procedure to determine of nutrients in sugarcane juice by inductively coupled plasma optical emission spectrometry (ICP OES) were applied. External calibration curves were used for direct analysis of the slurry. This procedure allowed determination of Ca, Cu, Fe, K and Mg with limits of detection (LoD) obtained of 2.0, 0.04, 0.2, 1.0 and 1.5 mg L-1, respectively. The precision was expressed as relative standard deviation (%RSD), being better than 1.4% (n = 3). Accuracy was confirmed by comparison with sample digestion method. The results for analysis of fourteen sugarcane juices samples demonstrated that the nutrients Ca, Cu, Fe, K and Mg have average contents of 108, 0.506, 6.40, 470 and 114 mg L 1, respectively. The proposed analytical method is a good alternative for simultaneous determination of nutrients in sugarcane juice using introduction of slurries and detection by ICP OES.

AB - Four species of bivalve molluscs (Anomalocardia brasiliana, Iphigenia brasiliana, Lucina pectinata and Trachycardium muricatum) were collected in the Todos os Santos Bay (TSB), Bahia, Brazil, in order to evaluate As, Cd, Co, Cu, Cr, Fe, Mn, Ni, Pb, Se, V and Zn levels and, consequently, the risk of bivalve mollusc consumption in humans. The samples were analyzed by inductively coupled plasma optical emission spectrometry (ICP OES) and inductively coupled plasma mass spectrometry (ICP-MS) after closed-vessel microwave digestion. The accuracy was confirmed using the certified reference materials of oyster tissue (NIST 1566b) and mussel tissue (NIST 2977), and the results were statistically equivalent to the certified values. Application of principal component analysis (PCA) and hierarchical cluster analysis (HCA) showed a tendency to form two groups between samples of Lucina pectinata and Trachycardium muricatum. All species showed As and Cr concentrations higher than the maximum tolerable limit specified in Brazilian legislation.

AB - Doehlert design and desirability function were used in the optimization of an ultrasound assisted dissolution method of fish fillet samples with tetramethyl ammonium hydroxide (TMAH) for the determination of Ca, Fe, Zn and Mg by flame atomic absorption spectrometry. The variables values after optimization were 620 MUL (volume of TMAH), 25 min (sonication time) and 46 degrees C (bath temperature). The quantification limits for Ca, Mg, Fe and Zn were 56, 107, 23 and 2.9 MUg g-1, respectively. Accuracy was evaluated by comparing the results generated from the analysis of the samples treated by the proposed method and by wet digestion. Additionally, accuracy for Fe and Zn was assessed by the analysis of certified reference materials Tort-3 (Lobster hepatopancreas), ERM-CE 278 (mussel tissue) and Dolt-4 (Fish liver). There were no significant differences between the results obtained at a 95% confidence level when results were evaluated by t-test application. PMID- 30292378 TI - Simultaneous identification of the wood types in aged cachacas and their adulterations with wood extracts using digital images and SPA-LDA. AB - Cachaca is a sugarcane-derived alcoholic spirit exclusively produced in Brazil. It can be aged in barrels made from different types of wood, similar to other distilled beverages. The choice of wood type promotes different effects on color, flavor, aroma and consequently the price of cachaca, favoring fraudulent activities. This paper proposes the simultaneous identification of different wood types in aged cachacas and their adulterations with wood extracts using a digital image based methodology employing color histograms obtained from digital images associated with pattern recognition methods, without any sample preparation step. Linear Discriminant Analysis, coupled with Successive Projections Algorithm for variable selection (SPA-LDA), obtained the best results, reaching accuracy, sensitivity, and specificity rates higher than 90.0% in the test set. This can be a rapid and reliable tool to prevent fraudulent labeling; ensuring that what is on the label reflects the quality of aged cachacas, affording security to consumers and regulatory agencies.

AB - Bee pollen consumption has increased in the last years, mainly due to its nutritional value and therapeutic applications. The quantification of mineral constituents is of great importance in order to evaluate both, the toxicity and the beneficial effect of essential elements. The purpose of this work was to quantify the essential elements, Ca, Mg, Zn, P and K, by diffuse reflectance spectra in the near infrared region (NIR) combined with partial least squares regression (PLS), which is a clean and fast method. Reference method used was ICP OES. The determination coefficients for calibration models (R2) were above 0.87 and the mean percent calibration error varied from 5 to 10%. For external validation R2 values were higher than 0.76. The results indicated that NIR spectroscopy can be useful for an approximate quantification of these minerals in bee pollen samples and can be used as a faster alternative to the standard methodologies. PMID- 30292380 TI - Evaluation of macro and micronutrient elements content from soft drinks using principal component analysis and Kohonen self-organizing maps. AB - This study approaches the determination of nine elements from Brazilian carbonated soft drinks of several flavors and manufactures using inductively coupled plasma optical emission spectrometry (ICP OES). The concentrations of the elements varied as follows: (in ug L-1: Cu: 4.00-78.0; Fe: 74.0-506; Mn: 20.0 66.0; Zn: 104-584) and (in mg L-1: Ca: 4.81-16.2; K: 6.73-260; Na: 26.0-175; S: 1.43-5.41; P: 0.186-219). Principal component analysis has shown some tendencies to form two groups according to the drink flavor (orange and cola), but only cola presented a clear and complete separation. Using Kohonen maps, it was observed a tendency to form three flavor groups: (i) cola, (ii) orange and lemon, and (iii) guarana. However, this last tool proved to be more accurate in the groups' formation. PMID- 30292381 TI - Direct determination of Ca, K, Mg, Na, P, S, Fe and Zn in bivalve mollusks by wavelength dispersive X-ray fluorescence (WDXRF) and laser-induced breakdown spectroscopy (LIBS). AB - This study aims to develop methods for determination of Ca, K, Mg and Na by laser induced breakdown spectroscopy (LIBS) and Ca, K, Mg, Na, P, S, Fe and Zn by wavelength dispersive X-ray fluorescence (WDXRF) in pressed pellets bivalve mollusks. LIBS and WDXRF calibration models were built with references values determined by inductively coupled plasma optical emission spectrometry (ICP OES) after acid digestion. The calibration models for LIBS and WDXRF were obtained from 28 samples (14 for calibration and 14 for validation). It was possible to implement a validation between LIBS and WDXRF methods for elements Ca, K, Mg and Na. The proposed calibration model obtained using LIBS and WDXRF data presented a good correlation with reference values obtained by ICP OES.

AB - Wet salting is an old preservation method however the NaCl has been frequently associated to high blood pressure issues. The KCl has been used as partial replacement without affecting the acceptability of the final product. In this study, the simultaneous diffusion of NaCl and KCl in champignon mushrooms in static brine and brine under agitation was modeled based on the generalization of Fick's second diffusion law and simulated using the finite element method. Main and crossed diffusion coefficients, as well as the Biot number, were determined using the super modified simplex optimization method by means of percentage error minimization. Deviations between the simulated and experimental data were 5.78% for NaCl and 4.78% for KCl in static brine and 4.95% for NaCl and 4.35% for KCl in brine with agitation and, the main diffusion coefficients 2.692 * 10-10 m2s-1 for sodium and 2.953 * 10-10 m2s-1 for potassium were obtained.

AB - INTRODUCTION: Infectious keratitis is a serious ocular infection that can lead to severe visual impairment and blindness. Bacterial pathogens are responsible for nearly half of infectious keratitis cases. This study was performed to determine the virulence factors, antimicrobial resistance patterns, and biofilm formation ability of Pseudomonas aeruginosa and Staphylococcus spp. strains isolated from corneal infections. METHODS: A total of 56 corneal scraping samples were collected over 8 months. P. aeruginosa and staphylococcal strains were identified by phenotypic and genotypic methods. Determination of multidrug resistance was performed according to its definition of multidrug resistance (MDR). Detection of antimicrobial resistance genes and determinants of virulence were also performed using standard procedures. Biofilm formation ability of the isolates was determined by colorimetric microtitration plate assay and Modified Congo red agar (MCRA). RESULTS: In the present study, P. aeruginosa, MSSA, MRSA, MS-CoNS and MR CoNS strains were isolated from corneal infections. Multidrug resistance was observed in 42.9% and 57.1% of P. aeruginosa and Staphylococcus spp., respectively. The most frequent virulence genes among P. aeruginosa strains were exoA and exoS (100%) followed by exoU (71.4%) and lasB (28.6%). All the P. aeruginosa isolates were biofilm producers and carried the algD gene (100%). All staphylococcal strains were negative for pvl gene amplification. Biofilm formation was also observed in 4 (57.1%) isolates. Both icaA and icaD genes were detected in the biofilm producers. CONCLUSION: Our results indicated that P. aeruginosa and Staphylococcus spp. were the most prevalent bacterial agents that cause corneal infections. However, their virulence traits and biofilm formation ability were noteworthy.

AB - Ubiquitous airborne conidia of the genus Aspergillus are responsible for a diverse group of human disorders from allergy to life treating invasive aspergillosis and mycotoxicoses. The aim of this study was to determine the population structure of Aspergillus isolated from outdoor air in Tehran by comparing the nucleotide sequences of ITS region and the PCR-RFLP molecular method. Internal transcribed spacer domains of 47 Aspergillus spp. were amplified and sequenced and PCR products were digested individually with restriction enzymes TaqI and EcoRI. For all species the PCR reaction produced a fragment of approximately 600bp in length. All of the nucleotide sequences were highly similar with the corresponding reference sequences registered at the gene bank. The all isolates displayed same banding pattern on the basis EcoR1 cleavage. While Taq1 enzyme profiling provided 5 different banding pattern. The results show that the A. niger section has the highest frequency with 27 isolates (57.4%). Of these, 23 isolates (48.9%) belonged to the A. niger complex and 4 isolates (8.5%) to the A. aculeatus complex. The A. flavus complex was also placed in the next ranking with 9 isolates (19.1%). These results strongly support the need for using molecular markers as an auxiliary tool in differentiating Aspergillus species. PMID- 30292393 TI - Effects of Doxorubicin on the Liquid-Liquid Phase Change Properties of Elastin Like Polypeptides. AB - The lower critical solution temperature (LCST) of the thermo-responsive engineered elastin-like polypeptide (ELP) biopolymer is being exploited for the thermal targeted delivery of doxorubicin (Dox) to solid tumors. We examine the impact of Dox labeling on the thermodynamic and hydrodynamic behavior of an ELP drug carrier and how Dox influences the liquid-liquid phase separation (LLPS). Turbidity, dynamic light scattering (DLS), and differential scanning calorimetry measurements show that ELP undergoes a cooperative liquid-liquid phase separation from a soluble to insoluble coacervated state that is enhanced by Dox labeling. Circular dichroism measurements show that below the LCST ELP consists of both random coils and temperature-dependent beta-turn structures. Labeling with Dox further enhances beta-turn formation. DLS measurements reveal a significant increase in the hydrodynamic radius of ELP below the LCST consistent with weak self-association. Dox-labeled SynB1-ELP1 (Dox-ELP) has a significant increase in the hydrodynamic radius by DLS measurements that is consistent with stable oligomers and, at high Dox-ELP concentrations, micelle structures. Enhanced association by Dox-ELP is confirmed by sedimentation velocity analytical ultracentrifugation measurements. Both ELP self-association and the ELP inverse phase transition are entropically driven with positive changes in enthalpy and entropy. We show by turbidity and DLS that the ELP phase transition is monophasic, whereas mixtures of ELP and Dox-ELP are biphasic, with Dox-labeled ELP phase changing first and unlabeled ELP partitioning into the coacervate as the temperature is raised. DLS reveals a complex growth in droplet sizes consistent with coalescence and fusion of liquid droplets. Differential scanning calorimetry measurements show a -11 kcal/mol change in enthalpy for Dox-ELP coacervation relative to the unlabeled ELP, consistent with droplet formation being stabilized by favorable enthalpic interactions. We propose that the ELP phase change is initiated by ELP self-association, enhanced by increased Dox-ELP oligomer and micelle formation and stabilized by favorable enthalpic interactions in the liquid droplets. PMID- 30292394 TI - RPS23RG1 Is Required for Synaptic Integrity and Rescues Alzheimer's Disease Associated Cognitive Deficits. AB - BACKGROUND: Although synaptic impairment is a prerequisite to cognitive deficiencies in Alzheimer's disease (AD), mechanisms underlying the dysregulation of essential synaptic scaffolding components and their integrity remain elusive. RPS23RG1 is a newly identified protein implicated in AD. However, the physiological function of RPS23RG1 has yet to be determined. METHODS: We investigated the role of RPS23RG1 in maintaining synaptic structure and function in cell cultures and in Rps23rg1 knockout mice and determined whether targeting RPS23RG1-mediated pathways has therapeutic potential in APP/PS1 AD model mice. RESULTS: Deletion of the Rps23rg1 gene resulted in severe memory deficits and impairment of postsynaptic structure and function, with marked reductions in postsynaptic densities-93 and -95 (PSD-93 and PSD-95) levels. RPS23RG1 interacted with PSD-93/PSD-95 through its intracellular domain, consequently sequestering PSD-93/PSD-95 from murine double minute 2-mediated ubiquitination and degradation, thereby maintaining synaptic function. Restoration of PSD-93/PS-D95 levels reversed synaptic and memory deficits in Rps23rg1 knockout mice. We further observed attenuated RPS23RG1 expression in human AD, which positively correlated with PSD-93/PSD-95 levels. Importantly, an RPS23RG1-derived peptide comprising a unique PSD-93/PSD-95 interaction motif rescued synaptic and cognitive defects in Rps23rg1 knockout and AD mouse models. CONCLUSIONS: Our results reveal a role for RPS23RG1 in maintaining synaptic integrity and function and provide a new mechanism for synaptic dysfunction in AD pathogenesis. This demonstrates that RPS23RG1-mediated pathways show good therapeutic potential in AD intervention. PMID- 30292395 TI - Reversing Behavioral, Neuroanatomical, and Germline Influences of Intergenerational Stress. AB - BACKGROUND: Stressors affect populations exposed to them as well as offspring. Strategies preventing the intergenerational propagation of effects of stress would benefit public health. Olfactory cue-based fear conditioning provides a framework to address this issue. METHODS: We 1) exposed adult male mice to an odor, acetophenone (Ace) or Lyral (parental generation [F0]-Exposed), 2) trained mice to associate these odors with mild foot shocks (F0-Trained), and 3) trained mice to associate these odors with mild foot shocks and then extinguished their fear toward these odors with odor-only presentations (F0-Extinguished). We then examined sensitivity of future generation (F1) offspring to these odors, expression of M71 odorant (Ace-responsive) and MOR23 odorant (Lyral-responsive) receptor-expressing cell populations in F1 offspring, and DNA methylation at genes encoding the Ace- (Olfr151, Olfr160) and Lyral- (Olfr16) responsive receptors in F0 sperm. RESULTS: Extinguishing fear toward Ace or Lyral of F0 male mice (F0-Extinguished) that had been fear conditioned with Ace or Lyral, respectively, results in F1-Extinguished offspring that do not demonstrate behavioral sensitivity to Ace or Lyral, respectively, and do not have enhanced representation for M71 or MOR23 odorant receptors in the olfactory system, as is observed in F1-Trained-Ace or F1-Trained-Lyral cohorts, respectively. The promoters of genes encoding Olfr151 and Olfr160 receptors are less methylated in F0-Trained-Ace sperm compared with F0-Exposed-Ace sperm. The Olfr16 promoter is less methylated in F0-Trained-Lyral sperm compared with F0-Exposed-Lyral sperm, and F0-Extinguished-Lyral sperm have methylation levels comparable to F0-Exposed Lyral sperm. CONCLUSIONS: Our study demonstrates the potential of using extinction-based behavioral strategies to reverse influences of parental stress in offspring and in the parental germline. PMID- 30292396 TI - The relationship of elbow alignment and kinematics on shoulder torque during the softball pitch: a biomechanical analysis of female softball pitchers. AB - BACKGROUND: Female softball pitchers commonly throw more pitches per game and season than their baseball counterparts. The greatest stress to the shoulder during a softball windmill pitch is at ball release (BR). This study investigated shoulder torques at BR among female softball pitchers and identified relationships to the kinematics of the elbow and forearm and alignment of the elbow (carrying angle and elbow extension). METHODS: High-speed 3-dimensional biomechanical analyses were performed in 33 pitchers (25 high school, 8 collegiate). Elbow and shoulder biomechanics at BR during fastball pitches and goniometric measures of carrying angle and elbow extension were collected and analyzed. RESULTS: Carrying angle correlated positively with shoulder extension torque at BR (rs = 0.371, P = .048) and forearm pronation at BR (rs = 0.370, P = .048). During the windmill pitch, the greater the elbow flexion, the greater shoulder adduction torque at BR (rs = -0.522, P = .007). Multiple regression analysis revealed that the carrying angle, passive elbow extension, and elbow flexion/extension angle at BR predicted shoulder flexion/extension torque at BR (F3,24 = 3.463, R2 = .302, P = .032.) CONCLUSIONS: Our findings demonstrate that shoulder torques during the softball fastpitch are influenced by the carrying angle and the kinematic elbow flexion angle at BR. Sports medicine clinicians and coaches should consider the role that the elbow carrying angle plays in creating shoulder stress when treating and training fastpitch softball players. PMID- 30292397 TI - Determining the in vitro susceptibility of Neisseria gonorrhoeae isolates from 8 cities in Guangdong Province through an improved microdilution method. AB - A microdilution method for the antibiotic susceptibility testing of Neisseria gonorrhoeae was established and improved, and the antibiotic resistance of N. gonorrhoeae samples isolated from 8 cities of Guangdong in 2016 was determined. The improved microdilution method was compared with the agar dilution method recommend by the World Health Organization (WHO) Western Pacific Region by testing the susceptibility of 100 clinical N. gonorrhoeae isolates. The essential agreement (EA), categorical agreement (CA), very major error (VME), major error (ME), and minor error (MIE) levels of the two methods were analyzed; the acceptable performance rates were measured as follows: >=90% for EA or CA, <=3% for VME or ME, and <=7% for MIE. The EA, CA, VME, ME, and MIE of each method for 7 antibiotics, penicillin, tetracycline, ciprofloxacin, spectinomycin, ceftriaxone, cefixime, and azithromycin, were 96%-100%, 94%-100%, 0%-3%, 0%-2%, and 0%-6%, respectively. The Wilcoxon signed-rank test results indicated 94%-100% agreement between the 2 methods after excluding off-scale values (P > 0.05). The susceptibility of 634 N. gonorrhoeae strains to the 7 antibiotics above were tested through the microdilution method. The resistant rates of the isolates against ciprofloxacin, tetracycline, penicillin, and azithromycin were 99.8%, 88.3%, 53.8%, and 11%, and the percentages of the isolates with decreased susceptibility to ceftriaxone (minimum inhibitory concentration [MIC] >=0.125 MUg/mL) and cefixime (MIC >=0.25 MUg/mL) were 2.1% and 12%, respectively, in Guangdong. Among 8 cities, Shenzhen had the highest rates of resistance against penicillin (77.8%) and decreased susceptibility against ceftriaxone (5.6%). Zhuhai had the highest rates of decreased susceptibility against cefixime (30.1%), and Jiangmen had the highest azithromycin-resistant isolates (16.8%). The findings from this study indicated that the improved microdilution method is an alternative for testing the antimicrobial susceptibility of N. gonorrhoeae. The resistance rates of N. gonorrhoeae against penicillin, tetracycline, and ciprofloxacin were high. While ceftriaxone, cefixime, and spectinomycin remained effective against N. gonorrhoeae, their effectiveness seemed to be decreasing over time. Azithromycin therapy requires timely susceptibility test results. PMID- 30292398 TI - Designed peptide with a flexible central motif from ranatuerins adapts its conformation to bacterial membranes. AB - The long-standing goal in the field of peptide antibiotics has been to design lead compounds that have a wide spectrum of excellent antibacterial activity but are nontoxic to human cells. Gram-negative and Gram-positive bacteria have very different membranes, which are additionally modified in some drug-resistant species, presenting a challenge for the design of a single membrane-active peptide able to adapt its conformation to various physical properties of membrane microenvironments. In this paper, we describe how a peptide sequence can be constructed starting from an adaptable dynamic turn tandem motif in a central location. The peptide, named flexampin, has been examined firstly by molecular dynamics simulations. It uses a flexible central motif and designed helix-forming cationic amphipathic arms to form a boomerang-like, L-shape, V-shape, and hairpin, super-secondary structures, whichever is the best in matching amphipathic and hydrophobic microenvironments it encounters. Secondly, activity measurements showed that flexampin is bactericidal at low micromolar concentrations against Gram-positive and Gram-negative strains including some multidrug resistant clinical isolates, while it is nontoxic for human circulating blood cells, does not cause DNA damage, and has good selectivity for bacterial cells in comparison to human cells. It is the first membrane-active peptide designed with the ability to self-adjust the orientation of its two cationic helical arms, 3D-hydrophobic moment, and dipole moment for obtaining a better grasp of anionic polar head groups at bacterial membrane surfaces. PMID- 30292399 TI - Effects of the peptide Magainin H2 on Supported Lipid Bilayers studied by different biophysical techniques. AB - Given the increasing trend in bacterial antibiotic resistance, research on antimicrobial peptides and their mechanisms of action has become of huge relevance in the last years. Several studies have investigated the effects of a large variety of antimicrobial peptides directly on bacteria or on model lipid bilayers. In the case of model lipid bilayers, different systems are typically exploited; however, different results could be obtained due to the specific properties of the used system. Supported Lipid Bilayers and Giant Unilamellar Vesicles are among the most popular model systems. Here we used Atomic Force Microscopy and fluorescence microscopy to study the interaction of the antimicrobial peptide Magainin H2, an analog of Magainin 2 with increased hydrophobicity, on Supported Lipid Bilayers. We found that, for this kind of model bilayer, due to its strong interaction with the support, the lateral expansion of the membrane induced by the interaction with the peptides is initially inhibited and subsequently proceeds creating new bilayer regions with many defects. This scenario gives rise in Supported Lipid Bilayers to effects like initial increase of lateral pressure, formation of lipid tubes to release this increase, or development of bilayer regions with lower lipid density. Our results highlight that care should be given to the selected model system when studying and comparing the interaction of peptides with other lipid bilayer model systems. PMID- 30292400 TI - Observer-based backstepping control method using reduced lateral dynamics for autonomous lane-keeping system. AB - This paper presents a backstepping control method with an augmented observer for an autonomous lane-keeping system. A novel reduced second-order model is also derived for an autonomous lane-keeping system. The proposed reduced model of lateral vehicle motion has the following advantages: (1) The lateral motion of the vehicle can be controlled with only simple linear second-order dynamics via the backstepping procedure; (2) The state variable of the reduced model includes the look-ahead distance similar to that for a human driver; (3) The system functions with unknown parameters and external disturbances can be lumped in the disturbance. An augmented observer is designed to estimate the full state and lumped disturbance, including the system functions with unknown parameters and external disturbances. A backstepping control is developed for improving the lateral control and compensation of the disturbance. The stability of the closed loop system is demonstrated using the input-to-state stable property. The lateral control performance of the proposed method is validated via numerical simulations using CarSim and MATLAB/Simulink.

AB - BACKGROUND: Sildenafil, a phosphodiesterase 5 (PDE5) inhibitor, is known to increase the intracellular level of cyclic guanosine monophosphate (cGMP), which causes vasodilation. However, the effect of sildenafil on human hair follicles (hHFs) is unknown. OBJECTIVE: The purpose of this study was to determine the role of sildenafil in hair growth. METHODS: We investigated the expression of PDE5 in human dermal papilla cells (hDPCs) and hHFs. The effects of sildenafil on hDPC proliferation were evaluated using BrdU assays. The mRNA expression of growth factors and extracellular signal-regulated kinase (ERK) phosphorylation were investigated using real-time PCR and western blotting, respectively. Additionally, anagen induction and perifollicular vessel formation were evaluated using an in vivo mice model. RESULTS: We confirmed high expression of PDE5 in hDPCs and hHFs. Sildenafil enhances proliferation of hDPCs and up-regulates the mRNA expression of vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF), which are responsible for hair growth. Additionally, sildenafil up-regulates the levels of phosphorylated ERK and accelerates anagen induction by stimulating perifollicular vessel formation after topical application in mice. CONCLUSION: Our study demonstrates for the first time, the significant therapeutic potential of sildenafil on hair growth and its potential use in treatment of alopecia. PMID- 30292405 TI - MFSD2A expression predicts better prognosis in gastric cancer. AB - Major facilitator superfamily domain containing-2A (MFSD2A) is reported to correlated with some tumors, but its clinical significance in gastric cancer (GC) is still unknown. The expression of MFSD2A and CD34 were examined on tissue microarrays of 170 set of GC and adjacent normal tissue (ANT) by immunohistochemistry. The relationship of MFSD2A with microvessel density (MVD) and clinicopathological characteristics was also investigated. MFSD2A expression is lower in GC tissue (35.3%) than in ANT (78.2%, P < 0.01). Mean MVD was higher in cancer tissue (49.7 +/- 5.46) than in ANT (19.3 +/- 2.19, P < 0.01), and higher in MFSD2A- GC (56.5 +/- 7.27), than in MFSD2A+ GC (24.8 +/- 4.31, P < 0.01). MFSD2A expression was significantly higher in moderately/well differentiated GC (47.4%) than in poorly differentiated GC (25.0%, P < 0.01) and in early-stage GC (46.4%) than in advanced GC (27.7%, P = 0.012). Patients with MFSD2A+ specimens (n = 60) had significantly better prognoses than the MFSD2A- group (n = 110; P < 0.0001). These results suggest that MFSD2A might affect angiogenesis and inhibit GC development and progression. MFSD2A may help predict prognosis and could be a therapeutic target in GC.

AB - In the present study, SREBP-1 cDNA was cloned from the hepatopancreas of mud crab (Scylla paramamosain) and characterized by performing rapid-amplification of cDNA ends. The 3361bp long full-length cDNA encodes a polypeptide with 1039 amino acids. Tissue distribution analysis revealed that SREBP-1 transcripts were widely distributed in various organs, with higher mRNA levels in the eyestalk and cranial ganglia. Further, expression level of SREBP-1 mRNA were up-regulated in proportion to the replacement of dietary fish oil (FO) with soybean oil (SO). These results may contribute to better understanding of the long-chain polyunsaturated fatty acids (LC-PUFA) biosynthetic pathway and regulation mechanism in mud crab.

AB - Cerebral ischemia-reperfusion-induced microglial activation causes neuronal death through the release of inflammatory cytokines. Increasing evidence suggests that microRNAs (miRNAs) exert a neuroprotective effect by modulating the inflammatory process in cerebral ischemia-reperfusion injury. Furthermore, Toll-like receptor 4 (TLR4) is increasingly being considered to have a significant role in the regulation of inflammation. However, whether miRNAs mediate their neuroprotective effects by regulating TLR4-mediated inflammatory responses remains unknown. To explore this gap in the literature, we conducted both in vitro and in vivo experiments. In vitro: BV2 cells were activated by oxygen-glucose deprivation (OGD). TLR4 and inflammatory cytokine (TNF-a, IL-6, and IL-1beta) transcription and translation expression levels were assessed using RT-PCR, ELISA, and western blot. BV2 cells were transfected with miR-182-5p mimics, inhibitors, siTLR4, or negative control (NC) using lipofectamine 2000 reagent. To confirm whether TLR4 is a direct target of miR-182-5p, we performed a luciferase reporter assay. In BV2 cells, we observed that OGD upregulated TLR4 expression, but downregulated miR-182-5p expression. We determined that miR-182-5p inhibited TLR4 by directly binding to its 3'-UTR. Furthermore, miR-182-5p suppressed the release of TNF-a, IL-6, and IL-1beta. In vivo: A middle cerebral artery occlusion (MCAO) rat model was used to mimic cerebral ischemia-reperfusion. Iba1 and TLR4 double staining was used to demonstrate that the target of miR-182-5p in microglial cells, and the mediator of the anti-inflammatory effect, is TLR4. TTC staining was performed to evaluate the infarct volume. Compared to the animals treated with miR-182-5p NC and normal saline, rats treated with miR-182-5p mimics demonstrated significantly enhanced neurological functions. TTC staining results were consistent with neurological function test findings. In summary, our data suggested that miR-182-5p exhibits potential neuroprotective effects in the cerebral ischemia-reperfusion injury via the regulation of the TLR4-mediated inflammatory response. PMID- 30292409 TI - Development of trophoblast cystic structures from human induced pluripotent stem cells in limited-area cell culture. AB - We developed a novel engineering technique to induce differentiation of human induced pluripotent stem cells (hiPSCs) into organoids mimicking the trophectoderm (TE). Here, hiPSCs were cultured on a limited area of 2-4 mm in diameter. After 15-20 days, spherical cysts appeared on the surface of the limited area. Secretion of human chorionic gonadotrophin (hCG) began to increase after ~ 20 days and remained dramatically elevated over the next 20 days. Limited area-cultured cysts exhibited expression of hCG, which was a result of epithelial differentiation. Low expression levels of pluripotent genes and high expression levels of trophoblast lineage-specific genes were detected in the cells of spherical cysts. Multinucleated syncytia trophoblast was observed in the reseeded cystic cells. We observed hiPSC-derived cysts that morphologically resembled trophectoderm in vivo. The limited-area cell culture induced a three-dimensional (3D) trophectoderm organoid, which has potential for use in the study of human trophoblast differentiation and placental morphogenesis. PMID- 30292408 TI - Kin1 kinase localizes at the hyphal septum and is dephosphorylated by calcineurin but is dispensable for septation and virulence in the human pathogen Aspergillus fumigatus. AB - Studies in yeasts have implicated the importance of Kin1 protein kinase, a member of the eukaryotic PAR1/MARK/MELK family, in polarized growth, cell division and septation through coordinated activity with the phosphatase, calcineurin. Kin1 is also required for virulence of the fungal pathogens Cryptococcus neoformans and Fusarium graminearum. Here we show that kin1 deletion in the human fungal pathogen Aspergillus fumigatus does not affect hyphal growth and septation but results in differential susceptibility to antifungals targeting the cell wall and cell membrane. The Deltakin1 strain remained virulent in a Galleria mellonella model of invasive aspergillosis. Expression of Kin1 tagged to GFP or RFP showed its stable localization at the septum. Co-localization experiments revealed calcineurin (CnaA) localization on either side of Kin1 at the septum suggesting possible interaction. Bimolecular fluorescence complementation assay confirmed the interaction of Kin1 with CnaA at the hyphal tips and septa in the presence of the antifungal caspofungin. Furthermore, phosphoproteomic analyses for the first time revealed Kin1 as a substrate of calcineurin providing novel insight into Kin1 regulation through calcineurin-mediated dephosphorylation mechanism. PMID- 30292410 TI - Enhanced antitumor effect of combination of annexin A1 knockdown and bortezomib treatment in multiple myeloma in vitro and in vivo. AB - Bortezomib (BTZ) is one of the most frequently used drugs in treatment of multiple myeloma (MM), but drug-resistance often occurs and limits its clinical efficacy. Annexin A1 (ANXA1) is upregulated in MM, and its knockdown enhances chemosensitivity in MM. However, whether ANXA1 inhibition can increase antitumor activity of BTZ in MM cells remains unknown. In the present study, Cell Counting Kit-8 (CCK-8) and colony formation assays showed that ANXA1 silencing combined with BTZ treatment led to a more significant inhibition of MM cell proliferation than each treatment alone. Cell apoptosis was dramatically promoted in MM cells following silencing of ANXA1 and BTZ administration versus that in ANXA1-silenced alone or BTZ-treated alone cells, as evidenced by decreased expression of phosphorylated signal transducers and activators of transcription 3 and BCL2, and increased expression of BAX. Moreover, we demonstrated that the levels of IL-6 and IL-23 were markedly downregulated in ANXA1-silenced and BTZ-treated MM cells. Furthermore, the combination of ANXA1 knockdown and BTZ treatment distinctly suppressed tumor growth in vivo compared with BTZ treatment alone. Taken together, our results show that downregulation of ANXA1 enhances antitumor activity of BTZ in MM in vitro and in vivo, indicating that ANXA1 may be a promising target for enhancing the chemosensitivity of MM to BTZ. PMID- 30292411 TI - A combination of irinotecan/cisplatinum and irinotecan/temozolomide or tumor targeting Salmonella typhimurium A1-R arrest doxorubicin- and temozolomide resistant myxofibrosarcoma in a PDOX mouse model. AB - Myxofibrosarcoma (MFS) is the most common sarcomas in elderly patients and is either chemo-resistant or recurs with metastasis after chemotherapy. This recalcitrant cancer in need of improved treatment. We have established a patient derived orthotopic xenograft (PDOX) of MFS. The MFS PDOX model was established in the biceps femoris of nude mice and randomized into 7 groups of 7 mice each: control; doxorubicin (DOX); pazopanib (PAZ); temozolomide (TEM); Irinotecan (IRN); IRN combined with TEM; IRN combined with cisplatinum (CDDP) and Salmonella typhimurium A1-R (S. typhimurium A1-R). Treatment was evaluated by relative tumor volume and relative body weight. The MFS PDOX models were DOX, PAZ, and TEM resistant. IRN combined with TEM and IRN combined with CDDP were most effective on the MFS PDOX. S. typhimurium A1-R arrested the MFS PDOX tumor. There was no significant body weight loss in any group. The present study suggests that the combination of IRN with either TEM or CDDP, and S. typhimurium have clinical potential for MFS. PMID- 30292412 TI - A role of GUNs-Involved retrograde signaling in regulating Acetyl-CoA carboxylase 2 in Arabidopsis. AB - In Arabidopsis thaliana (Arabidopsis), Acetyl-CoA Carboxylase 2 (ACC2) is a nuclear DNA-encoded and plastid-targeted enzyme that catalyzes the conversion of acetyl-CoA to malonyl-CoA. ACC2 improves plant growth and development when chloroplast translation is impaired. However, little is known about the upstream signals that regulate ACC2. Here, through analyzing the transcriptome changes in brz-insensitive-pale green (bpg) 2-2, a pale-green mutant with impaired chloroplast gene expression resulting from loss of the BPG2 function, we found that the level of ACC2 was significantly up-regulated. Through performing genetic analysis, we further demonstrated that loss of the GENOMES UNCOUPLED 1 (GUN1) or GUN5 function partly perturbed the up-regulation of ACC2 in the bpg2-2 mutant, whereas ABA INSENSITIVE 4 (ABI4)-function-loss had no clear effect on the ACC2 expression. Furthermore, when plants were treated with plastid translation inhibitors, such as lincomycin and spectinomycin, the ACC2 transcriptional level was also markedly increased in a GUN-dependent manner. In conclusion, our results suggested that the GUN-involved plastid-to-nucleus retrograde communication played a role in regulating ACC2 in Arabidopsis. PMID- 30292414 TI - LncRNA-CIR promotes articular cartilage degeneration in osteoarthritis by regulating autophagy. AB - Osteoarthritis (OA) is a common joint disease that is regarded as a local inflammatory response caused by joint instability and accompanied by the progressive degeneration of articular cartilage. However, the molecular mechanisms involved in the maintenance of articular cartilage remain a subject of debate and research. This study aims to analyze the roles of long noncoding RNA (lncRNA)CIR and autophagy in cartilages and determine their overall contribution to the degradation of extracellular matrix. Patients with OA possessed high levels of lncRNA-CIR and MMP3 and low level of COL2A1. The levels of autophagy related proteins, including LC3BI/II and beclin-1, increased from 12 h to 48 h. The use of si-lncRNA-CIR reversed the trend compared with that in the OA group. The negative effect of lncRNA-CIR was assessed in vivo by establishing a model of surgically induced OA. Moreover, si-lncRNA-CIR-treated joints exhibited fewer OA changes than saline-treated joints. Results were confirmed by histopathological grading of the models by using the Osteoarthritis Research Society International Scoring System and the outcomes of immunohistochemistry for LC3B-II and MMP-3. Overall, lncRNA-CIR played a negative role in the OA process by activating autophagy. PMID- 30292413 TI - Inflammatory production of reactive oxygen species by Drosophila hemocytes activates cellular immune defenses. AB - The production of reactive oxygen species (ROS) is a prominent response to infection among innate immune cells such as macrophages and neutrophils. To better understand the relationship between antimicrobial and regulatory functions of blood cell ROS, we have characterized the ROS response to infection in Drosophila hemocytes. Using fluorescent probes, we find a biphasic hemocyte ROS response to bacterial infection. In the first hour, virtually all hemocytes generate a transient ROS signal, with nonphagocytic cells including prohemocytes and crystal cells displaying exceptionally strong responses. A distinct, and more delayed ROS response starting at 90 min is primarily within cells that have engulfed bacteria, and is sustained for several hours. The early response has a clear regulatory function, as dampening or intensifying the intracellular ROS level has profound effects on plasmatocyte activation. In addition, ROS are necessary and sufficient to activate JNK signalling in crystal cells, and to promote JNK-dependent crystal cell rupture. These findings indicate that Drosophila will be a promising model in which to dissect the mechanisms of ROS stimulation of immune activation. PMID- 30292415 TI - Beneficial effects of anodal transcranial direct current stimulation (tDCS) on spatial working memory in patients with schizophrenia. AB - Schizophrenia is a severe and often detrimental psychiatric disorder. The individual patients' level of functioning is essentially determined by cognitive, particularly working memory (WM), deficits that are critically linked to dysfunctional activity of the dorsolateral prefrontal cortex (dlPFC). Transcranial direct current stimulation (tDCS) can transiently modulate activity of the dlPFC and remote areas and has been shown to improve WM functions. It may therefore provide a new, targeted treatment option. For this aim, the present study investigated the effect of anodal tDCS of different intensities on spatial WM in patients with schizophrenia. In two experiments, 32 patients performed a spatial n-back task with increasing WM load (1-, 2-, and 3-back) at baseline and in two sessions with anodal or sham tDCS (EXP I [n = 16]: 1 mA; EXP II [n = 16]: 2 mA) to the right dlPFC (cathode: left m. deltoideus). With 1 mA anodal tDCS, no effect on WM performance could be detected. However, 2 mA anodal tDCS increased accuracy (measured by d') of the task with the highest WM load (3-back). This effect was larger in patients with a lower level of general neurocognitive functioning. These results demonstrate a beneficial effect of 2 mA anodal tDCS on deficient WM accuracy in patients with schizophrenia particularly under challenging conditions and in subjects with higher cognitive impairments. This data will inform future clinical trials on tDCS-enhanced cognitive training to improve treatment of schizophrenia. PMID- 30292416 TI - Role of conduct problems in the relation between Attention-Deficit Hyperactivity disorder, substance use, and gaming. AB - Known comorbidities for Attention-Deficit Hyperactivity Disorder (ADHD) include conduct problems, substance use disorder and gaming. Comorbidity with conduct problems may increase the risk for substance use disorder and gaming in individuals with ADHD. The aim of the study was to build a causal model of the relationships between ADHD and comorbid conduct problems, and alcohol, nicotine, and other substance use, and gaming habits, while accounting for age and sex. We used a state-of-the-art causal discovery algorithm to analyze a case-only sample of 362 ADHD-diagnosed individuals in the ages 12-24 years. We found that conduct problem severity mediates between ADHD severity and nicotine use, but not with more severe alcohol or substance use. More severe ADHD-inattentive symptoms lead to more severe gaming habits. Furthermore, our model suggests that ADHD severity has no influence on severity of alcohol or other drug use. Our findings suggest that ADHD severity is a risk factor for nicotine use, and that this effect is fully mediated by conduct problem severity. Finally, ADHD-inattentive severity was a risk factor for gaming, suggesting that gaming dependence has a different causal pathway than substance dependence and should be treated differently. By identifying these intervention points, our model can aid both researchers and clinicians. PMID- 30292417 TI - Stroke Epidemiology in Argentina. Design of a Population-Based Study in General Villegas (EstEPA). AB - BACKGROUND: Epidemiological data on stroke is scarce in Latin America. Estudio Epidemiologico Poblacional sobre Accidente Cerebrovascular (EstEPA) is a population-based program planned to assess prevalence, incidence, mortality, and burden of disease for stroke in the Department of General Villegas, province of Buenos Aires, Argentina. METHODS AND DESIGN: Prevalence study will consist of a two-phase survey approach in the urban area of General Villegas. First, trained social workers with a structured questionnaire will collect data in 2000 randomly selected housing units. Those subjects screened positive for possible strokes will be interviewed and examined by stroke neurologists to confirm diagnosis. The incidence study will be performed according to the methodology of WHO STEPS stroke surveillance manual and will detect all new strokes in the department during a 5-year period. General and disease-specific mortality rates will be assessed monthly during a 5-year period, using different sources of information. To assess the overall burden of cerebrovascular disease, disability adjusted life years will be calculated. DISCUSSION: EstEPA will assess for the first time all aspects of stroke epidemiology in Argentina. Its results will help to implement population-based interventions and to properly allocate public health resources. PMID- 30292418 TI - Multidisciplinary treatment of lung cancer in older patients: A review. AB - Lung cancer is the leading cause of cancer death worldwide. Older patients represent approximately half of the patient population and optimal management of these patients is challenging. In early-stagenon-small cell lung cancer (NSCLC), lobectomy should be considered in fit older patients. For unfit patients, stereotactic body radiotherapy (SBRT) represents a good alternative. While data on the benefit and risk of concurrent chemo-radiotherapy (cCRT) in older patients with locally advanced NSCLC is conflicting, age alone should not preclude cCRT. Multidisciplinary collaboration is essential for appropriate patient selection. In limited disease small cell lung cancer (SCLC), older patients appear to benefit similarly from standard treatment compared to their younger counterparts, however, with a higher risk of toxicity. Appropriately selected older patients with lung cancer seem to derive as much benefit from active oncological treatment as their younger counterparts. Geriatric screening tests and comprehensive geriatric assessments (CGA) can be helpful when choosing between treatment strategies. Older patients are at risk for under-treatment; this should be avoided by proper selection and multidisciplinary management. This review outlines the management of lung cancer in older patients. PMID- 30292419 TI - Modern Management of the Failed Bladder Exstrophy Closure: A 50-yr Experience. AB - BACKGROUND: A failed closure of classic bladder exstrophy (CBE) has a negative long-term impact on the patient and the health care system. OBJECTIVE: To investigate the outcomes of CBE patients with failed primary bladder closure. DESIGN, SETTING, AND PARTICIPANTS: A database of 1317 exstrophy-epispadias complex patients was retrospectively reviewed for CBE patients with failed primary bladder closure from 1965 to 2017 with subsequent repeat closure. INTERVENTION: Repeat bladder exstrophy closure and subsequent continence procedure. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Failed exstrophy closures are defined as occurrence of bladder prolapse, dehiscence, vesicocutaneous fistula, outlet obstruction, or combination of these factors. Successful repeat closures are defined as closures that require no further operative intervention as a consequence of these factors. Kaplan-Meier to determine time to successful repeat closure and receiver operator characteristic curve to determine the optimal time for secondary closure were determined. RESULTS AND LIMITATIONS: In total, 170 CBE patients had at least one repeat closure following a failed primary closure (115 male/55 female). With continued closure attempts, 166/170 (97.6%) patients were successfully closed. The median time to successful closure from birth was 12.9 mo (95% confidence interval: 11.7 15.7). Furthermore, 52/153 (34%) patients had more than one osteotomy. Of 215 total osteotomies, 50 (29.4%) were performed during the 170 failed primary closures, 128 (75.3%) during the 170second closures, and 27 (64.3%) during the 42 third closures. Of 96 patients with available continence data, 74 (77.1%) achieved urinary continence. CONCLUSIONS: A successful repeat closure is possible, especially when used in conjunction with a pelvic osteotomy. Continent urinary diversion yielded the highest continence rate in this cohort. PATIENT SUMMARY: We looked at outcomes of classic bladder exstrophy closure in a large population. Successful repeat closure is possible in the majority of cases when used with pelvic osteotomy. A majority of patients achieved urinary continence using a continent diversion. PMID- 30292420 TI - Current Evidence on Nonantibiotic Prevention of Recurrent Urinary Tract Infections. AB - Clinicians should be aware of the limited evidence on nonantibiotic prophylactic treatment for recurrent urinary tract infections. Owing to the rising antibiotic resistance rates worldwide, nonantibiotic prevention strategies should be considered for patient care. Further research is necessary to evaluate nonantibiotic treatment strategies using a robust randomised controlled trial methodology to contribute to a strong evidence basis. PMID- 30292421 TI - Metastases-yield and Prostate-specific Antigen Kinetics Following Salvage Lymph Node Dissection for Prostate Cancer: A Comparison Between Conventional Surgical Approach and Prostate-specific Membrane Antigen-radioguided Surgery. AB - : The first results on 99mTechnetium prostate-specific membrane antigen radioguided surgery (99mTc-PSMA- RGS) showed promising outcome. Here, we sought to evaluate if this targeted molecular surgical approach might be more effective than conventional salvage lymph node dissection (sLND). We prospectively analysed 42 consecutive patients who underwent sLND based on preoperative 68Gallium (68Ga) PSMA-positron emission tomography (PET) imaging between 2015 and 2018. In 29 patients, the dissection field was based solely 68Ga-PSMA-PET imaging (conventional surgical approach [CSA]), whereas 13 patients underwent 99mTc-PSMA RGS. Preoperative characteristics of both groups were similar. Final pathology revealed no metastases in nine CSA patients (31%), whereas all visible lesions on preoperative 68Ga-PSMA-PET were removed in patients who underwent RGS. A PSA decline in general, >50% and >90% within 6 wk was seen in 50%, 29%, and 7% versus 100%, 92%, and 53% in CSA versus RGS groups, respectively (all p<0.01). This is the first comparison of conventional and PSMA-radioguided approach with regards to short-term efficacy of sLND. Although long-term outcome needs to be awaited, RGS offers promising results. PATIENT SUMMARY: We compared two surgical approaches for lymph node dissection in lymph node only recurrent prostate cancer patients. The radioguided approach was superior in removing the affected lymph nodes, resulting in a more pronounced prostate-specific antigen decline. PMID- 30292422 TI - Prostatic Artery Embolization versus Standard Surgical Treatment for Lower Urinary Tract Symptoms Secondary to Benign Prostatic Hyperplasia: A Systematic Review and Meta-analysis. AB - CONTEXT: Prostatic artery embolization (PAE) has been introduced into clinical practice for the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH-LUTS) despite a lack of high-level evidence. OBJECTIVE: To perform a systematic review and meta-analysis of clinical trials comparing efficacy and safety of PAE versus established surgical therapies. EVIDENCE ACQUISITION: Medline, Embase, and York CRD were searched up to June 23, 2018. Only comparative studies were included. The risk of bias was assessed by the Cochrane Collaboration tool. Meta-analyses were performed using RevMan 5.3. EVIDENCE SYNTHESIS: Five studies including 708 patients met the selection criteria. Risk of bias was rated high for most of the studies. Mean reduction in the International Prostate Symptom Score was lower after PAE compared with standard surgical therapies (mean difference 3.80 points [95% confidence interval: 2.77-4.83]; p<0.001). PAE was less efficient regarding improvements in all functional parameters assessed including maximum urinary flow, post void residual, and reduction of prostate volume. In contrast, patient-reported erectile function (International Index of Erectile Function 5) was better after PAE and significantly fewer adverse events occurred after PAE. CONCLUSIONS: Moderately strong evidence confirms efficacy and safety of PAE in the treatment of BPH-LUTS in the short term. Significant advantages regarding safety and sexual function, but clear disadvantages regarding all other patient-reported and functional outcomes were found for PAE. Large-scale randomized controlled trials including longer follow-up periods are mandatory before PAE can be considered as a standard therapy and to define the ideal indication for PAE in the management of BPH-LUTS. PATIENT SUMMARY: We reviewed the role of prostatic artery embolization (PAE) in the treatment of symptoms associated with benign overgrowth of the prostate. The results suggest that PAE is not as effective as established surgical therapies but has fewer side effects. Further research is required to determine whether PAE is the best treatment for certain types of patients. PAE should, therefore, not yet be considered a standard treatment. PMID- 30292424 TI - Facing obesity: Adapting the collaborative deliberation model to deal with a complex long-term problem. AB - OBJECTIVE: Care communication about obesity needs to respond to the complex biopsychosocial processes that affect weight and health. The collaborative deliberation model conceptualizes interpersonal work that underpins empathic communication and shared decision-making. The goal of this study was to elucidate how primary care practitioners can use the model to achieve shared obesity assessment and care planning. METHODS: This qualitative study used direct observation of clinical encounters with twenty patients with obesity sampled for maximum variation in context, semi-structured patient and provider interviews, patient journals and two follow-up interviews over eight weeks. Themes were compared to the original model. RESULTS: We identified five processes that may be relevant for collaborative deliberation about obesity in addition to the original model: (1) Exploring the story, (2) Reframing the story, (3) Co-constructing a new story, (4) Choosing a priority, and (5) Experimenting with alternatives. CONCLUSIONS: We propose an enhanced collaborative deliberation model for obesity that describes the interpersonal work needed before and after deliberation about preferences and courses of action. PRACTICE IMPLICATIONS: The enhanced model can support clinicians in achieving meaningful conversations about obesity and complex chronic disease resulting in care plans that are responsive to and achievable in the patient's lifeworld. PMID- 30292423 TI - Biocompatible bacteria-derived vesicles show inherent antimicrobial activity. AB - Up to 25,000 people die each year from resistant infections in Europe alone, with increasing incidence. It is estimated that a continued rise in bacterial resistance by 2050 would lead up to 10 million annual deaths worldwide, exceeding the incidence of cancer deaths. Although the design of new antibiotics is still one way to tackle the problem, pharmaceutical companies investigate far less into new drugs than 30 years ago. Incorporation of antibiotics into nanoparticle drug carriers ("nanoantibiotics") is currently investigated as a promising strategy to make existing antibiotics regain antimicrobial strength and overcome certain types of microbial drug resistance. Many of these synthetic systems enhance the antimicrobial effect of drugs by protecting antibiotics from degradation and reducing their side effects. Nevertheless, they often cannot selectively target pathogenic bacteria and - due to their synthetic origin - may induce side-effects themselves. In this work, we present the characterisation of naturally derived outer membrane vesicles (OMVs) as biocompatible and inherently antibiotic drug carriers. We isolated OMVs from two representative strains of myxobacteria, Cystobacter velatus Cbv34 and Sorangiineae species strain SBSr073, a bacterial order with the ability of lysing other bacterial strains and currently investigated as sources of new secondary metabolites. We investigated the myxobacterias' inherent antibacterial properties after isolation by differential centrifugation and purification by size-exclusion chromatography. OMVs have an average size range of 145-194 nm. We characterised their morphology by electron cryomicroscopy and found that OMVs are biocompatible with epithelial cells and differentiated macrophages. They showed a low endotoxin activity comparable to those of control samples, indicating a low acute inflammatory potential. In addition, OMVs showed inherent stability under different storage conditions, including 4 degrees C, -20 degrees C, -80 degrees C and freeze-drying. OMV uptake in Gram-negative model bacterium Escherichia coli (E. coli) showed similar to better incorporation than liposome controls, indicating the OMVs may interact with model bacteria via membrane fusion. Bacterial uptake correlated with antimicrobial activity of OMVs as measured by growth inhibition of E. coli. OMVs from Cbv34 inhibited growth of E. coli to a comparable extent as the clinically established antibiotic gentamicin. Liquid-chromatography coupled mass spectrometry analyses revealed the presence of cystobactamids in OMVs, inhibitors of bacterial topoisomerase currently studied to treat different Gram-negative and Gram-positive pathogens. This work, may serve as an important basis for further evaluation of OMVs derived from myxobacteria as novel therapeutic delivery systems against bacterial infections. PMID- 30292425 TI - 'Breast cancer won't kill ya in the breast': Broaching a rationale for chemotherapy during the surgical consultation for early-stage breast cancer. AB - OBJECTIVE: To examine how, and for what interactional purpose, a surgeon raises the risk of death with an early-stage breast cancer patient. METHOD: Single-case analysis of a recorded surgical consultation, using conversation analysis. RESULTS: The surgeon not only negotiates the surgical treatment decision with the patient, she provides an overview of what her non-surgical treatment is likely to entail. Analysis reveals how the surgeon addresses interactional challenges when providing this overview, including how to broach the rationale for administering chemotherapy, the possibility that cancer could spread to vital organs and prove fatal. To do this, the surgeon orients to the possibility that the patient has misconceptions about her risk of dying from breast cancer. She uses negatively formulated assertions to invoke these possible misconceptions, making correction relevant and providing a point of entry into delicate interactional territory. CONCLUSION: The surgeon draws upon possible patient misconceptions to broach the rationale for administering adjuvant chemotherapy. PRACTICE IMPLICATIONS: The surgical consultation is typically the first treatment-related consultation newly diagnosed breast cancer patients have and represents an opportunity to educate patients and prepare them for future treatment decisions. The challenges of providing and receiving such overviews, and how they may influence future treatment decisions, merit consideration. PMID- 30292426 TI - Pharmacologic Treatment of Intensive Care Unit Delirium and the Impact on Duration of Delirium, Length of Intensive Care Unit Stay, Length of Hospitalization, and 28-Day Mortality. AB - OBJECTIVE: To determine whether treatment of delirium affects outcomes. PATIENTS AND METHODS: A retrospective cohort study of patients admitted to the medical intensive care unit (ICU) from July 1, 2015, through June 30, 2016, was conducted. Patients with ICU delirium, defined by a positive Confusion Assessment Method for the ICU score, were included. Patients were stratified into 4 treatment groups based on exposure to melatonin and antipsychotic agents during ICU stay: no pharmacologic treatment, melatonin only, antipsychotics only, and both melatonin and antipsychotics. A time-dependent cause-specific hazards model with death as a competing risk was used to evaluate the effect of melatonin or antipsychotic drug use for delirium on duration of ICU delirium, length of ICU stay, and length of hospitalization. A logistic regression was used to evaluate 28-day mortality. Covariates significantly associated with exposure to melatonin and antipsychotics were included in the minimally adjusted model. Covariates significantly associated in the minimally adjusted model were included in a final adjusted model. RESULTS: A total of 449 admissions to the medical ICU were included in the analysis. Exposure to melatonin or antipsychotic agents did not reduce the duration of ICU delirium, ICU/hospital length of stay, or 28-day mortality. However, antipsychotic use only was associated with longer hospitalization. CONCLUSION: Antipsychotic drugs for the treatment ICU delirium may not provide the benefit documented in earlier literature. Further investigation on patient selection, type of antipsychotic, and dosing is needed. PMID- 30292427 TI - India's escalating burden of non-communicable diseases. PMID- 30292428 TI - Effect of sildenafil citrate treatment in the eNOS knockout mouse model of fetal growth restriction on long-term cardiometabolic outcomes in male offspring. AB - Fetal growth restriction (FGR) is associated with an increased risk of hypertension, insulin resistance, obesity and cardiovascular disease in adulthood. Currently there are no effective treatments to reverse the course of FGR. This study used the eNOS knockout mouse (eNOS-/-), a model of FGR, to determine the ability of sildenafil, a potential new treatment for FGR, to improve cardiovascular and metabolic outcomes in adult offspring following a complicated pregnancy. Pregnant eNOS-/- and C57BL/6J control dams were randomised to sildenafil treatment (0.2 mg/ml in drinking water) or placebo at day 12.5 of gestation until birth. After weaning, male offspring were randomised to either a high fat (HFD; 45% kcal from fat) or normal chow diet (ND), and raised to either postnatal day 90 or 150. Growth and body composition, glucose tolerance, insulin resistance, systolic blood pressure and vascular function were analysed at both time-points. eNOS-/- offspring were significantly smaller than their C57BL/6J controls at weaning and P90 (p < 0.01); at P150 they were a similar weight. Total adipose tissue deposition at P90 was significantly increased only in eNOS-/- mice fed a HFD (p < 0.001). At P150 both C57BL/6J and eNOS-/- offspring fed a HFD demonstrated significant adipose tissue deposition (p < 0.01), regardless of maternal treatment. Both diet and maternal sildenafil treatment had a significant effect on glucose tolerance. Glucose tolerance was significantly impaired in eNOS /- mice fed a HFD (p < 0.01); this was significant in offspring from both sildenafil and vehicle treated mothers at P90 and P150. Glucose tolerance was also impaired in C57BL/6J mice fed a HFD at both P90 and P150 (p < 0.01), but only in those also exposed to sildenafil. In these C57BL/6J mice, sildenafil was associated with impaired insulin sensitivity at P90 (p = 0.020) but increased insulin resistance at P150 (p = 0.019). Exposure to sildenafil was associated with a significant increase in systolic blood pressure in eNOS-/- mice compared with their C57BL/6J diet controls at P150 (p < 0.05). Exposure to sildenafil had differing effects on vascular function in mesenteric arteries; it increased vasodilation in response to ACh in C57BL/6J mice, but was associated with a more constrictive phenotype in eNOS-/- mice. eNOS-/- mice demonstrate a number of impaired outcomes consistent with programmed cardiometabolic disease, particularly when faced with the 'second hit' of a HFD. Exposure to sildenafil treatment during pregnancy did not increase fetal growth or significantly improve adult metabolic or cardiac outcomes. Maternal sildenafil treatment was, however, associated with small impairments in glucose handling and an increase in blood pressure. This study highlights the importance of understanding the long-term effects of treatment during pregnancy in offspring from both complicated and healthy control pregnancies. PMID- 30292429 TI - Leptin and insulin do not exert redundant control of metabolic or emotive function via dopamine neurons. AB - Leptin and insulin's hunger-suppressing and activity-promoting actions on hypothalamic neurons are well characterized, yet the mechanisms by which they modulate the midbrain dopamine system to influence energy balance remain less clear. A subset of midbrain dopamine neurons express receptors for leptin (Lepr) and insulin (Insr). Leptin-dopamine signaling reduces running reward and homecage activity. However, dopamine-specific deletion of Lepr does not affect body weight or food intake in mice. We hypothesized insulin-dopamine signaling might compensate for disrupted leptin-dopamine signaling. To investigate the degree to which insulin and leptin exert overlapping (i.e. redundant) versus discrete control over dopamine neurons, we generated transgenic male and female mice exhibiting dopamine-specific deletion of either Lepr (Lepr KO), Insr (Insr KO) or both Lepr and Insr (Dbl KO) and assessed their feeding behavior, voluntary activity, and energy expenditure compared to control mice. No differences in body weight, daily food intake, energy expenditure or hyperphagic feeding of palatable chow were observed between Lepr, Insr or Dbl KO mice and control mice. However, consistent with previous findings, Lepr KO (but not Insr or Dbl KO) male mice exhibited significantly increased running wheel activity compared to controls. These data demonstrate that insulin and leptin do not exert redundant control of dopamine neuron-mediated modulation of energy balance. Furthermore, our results indicate neither leptin nor insulin plays a critical role in the modulation of dopamine neurons regarding hedonic feeding behavior or anxiety-related behavior.

Whether this is mediated by systemic signalling remained unclear. Recently, Xu et al. [1] (Nat.

PMID- 30292431 TI - Ecological Function Analysis: Incorporating Species Roles into Conservation. AB - Effective conservation strategies must ensure that species remain not just extant, but able to maintain key roles in species interactions and in the maintenance of communities and ecosystems. Such ecological functions, however, have not been well incorporated into management or policy. We present a framework for quantifying ecological function that is complementary to population viability analysis (PVA) and that allows function to be integrated into strategic planning processes. Ecological function analysis (EFA) focuses on preventing secondary extinctions and maintaining ecosystem structure, biogeochemical processes, and resiliency. EFA can use a range of modeling approaches and, because most species interactions are relatively weak, EFA needs to be performed for relatively few species or functions, making it a realistic way to improve conservation management.

AB - BACKGROUND: The majority of children supported with ventricular assist devices (VADs) are bridged to heart transplantation. Although bridge to recovery has been reported, low recovery patient numbers has precluded systematic analysis. The aim of this study was to delineate recovery rates and predictors of recovery and to report on long-term follow-up after VAD explantation in children. METHODS: Children bridged to recovery at our institution from January 1990 to May 2016 were compared with a non-recovery cohort. Clinical and echocardiographic data before and at pump stoppages and after VAD explantation were analyzed. Kaplan Meier estimates of event-free survival, defined as freedom from death or transplantation after VAD removal, were determined. RESULTS: One hundred forty nine children (median age 5.8 years) were identified. Of these, 65.2% had cardiomyopathy, 9.4% had myocarditis, and 24.8% had congenital heart disease. The overall recovery rate was 14.2%, and was 7.1% in patients with dilated cardiomyopathy. Predictors of recovery were age <2 years (recovery rate 27.8%, odds ratio [OR] 5.64, 95% confidence interval [CI] 2.0 to 16.6) and diagnosis of myocarditis (rate 57.1%; OR 17.56, 95% CI 4.6 to 67.4). After a median follow-up of 10.8 years, 15 patients (83.3%) were in Functional Class I and 3 (16.7%) in were in Class II. Mean left ventricular ejection fraction was 53% (range 28% to 64%). Ten- and 15-year event-free survival rates were both 84.1 +/- 8.4%. CONCLUSIONS: Children <2 years of age and those diagnosed with myocarditis have the highest probability of recovery. Long-term survival after weaning from the VAD was better than after heart transplantation, as demonstrated in the excellent long-term stability of ejection fraction and functional class. PMID- 30292434 TI - Prognostic value of dual imaging stress echocardiography following coronary bypass surgery. AB - AIMS: To assess the prognostic value of dual imaging stress echocardiography after coronary artery bypass grafting (CABG). Dual imaging stress echocardiography, combining the evaluation of regional wall motion and Doppler echocardiographic derived coronary flow velocity reserve (CFVR) of the left anterior descending artery (LAD), is the state-of-the-art methodology during vasodilatory stress. METHODS AND RESULTS: In a prospective, multicenter, observational study, 349 patients (270 men; 69 +/- 9 years; 262 symptomatic) with history of CABG underwent high-dose dipyridamole (0.84 mg/kg over 6 min) stress echocardiography with CFVR evaluation of LAD by Doppler. The composite endpoint of death and myocardial infarction was considered in the survival analysis. Positivity rate with either criteria was 13% in the 262 symptomatic patients with appropriate and 6% in the 87 asymptomatic patients with maybe/rarely appropriate indications on the basis of 2014 American College of Cardiology Foundation guidelines. During a median follow-up of 22 months (1st quartile 8, 3rd quartile 44), there were 56 (16%) events: 21 deaths, and 35 nonfatal myocardial infarctions. At Cox analysis, ischemia at stress echo (HR 4.80, 95% CI 2.69-8.55; p < 0.0001), and CFVR of LAD <=2 (HR 2.28, 95% CI 1.32-3.95; p = 0.003) were multivariable prognostic predictors. Considering the group with no ischemia, patients with CFVR <=2 showed 2.5 fold higher yearly hard events as compared to those with CFVR >2 (7.5 vs 2.9%; p = 0.002). CONCLUSIONS: Dual imaging stress echocardiography provides useful prognostic information following CABG. Inducible ischemia and abnormal CFVR are strong and independent prognostic indicators in patients with appropriate and rarely/maybe appropriate indications. PMID- 30292435 TI - Prevalence and significance of T-wave inversion in children practicing sport: A prospective, 4-year follow-up study. AB - BACKGROUND: T-wave inversion (TWI) is rare in athlete's heart but is a common manifestation in cardiomyopathies. Although TWI has been extensively investigated in adult athletes, the ability of this ECG pattern to distinguish between a physiological variant and a developing heart muscle disease in children is controversial. The aim of this longitudinal study was to establish the prevalence, changes and clinical significance of TWI in a large cohort of pre adolescent athletes. METHODS: 2227 children (mean age 12.3 +/- 2.0 years) undergoing sports preparticipation screening were included. Children with TWI underwent yearly follow-up until the positivisation of TWI for a maximum follow up of 4 years. RESULTS: Among 2227 children, 358 (16%) had TWI. Children with TWI were younger (11.4 +/- 2.1 vs. 12.5 +/- 2.0 years, p < 0.0001) and had a lower BSA than children without TWI (p < 0.0001). 97% of children showed anterior TWI while only 3% had infero-lateral TWI. Anterior TWI became positive in 94% of children during the 4-year follow-up (p < 0.0001 vs. baseline) and the remaining 6% did not show abnormal clinical findings. Conversely, in the group of 9 children with infero-lateral TWI, only 1 showed normalisation during follow-up (p = 0.81) and 1 was found to have a cardiomyopathy. CONCLUSIONS: Anterior TWI is common in children and generally becomes positive by the age of 14 years. Conversely, infero-lateral TWI is rare, persistent and may be associated with structural heart disease. Therefore, infero-lateral TWI should not be interpreted as physiologically related to age, development or training and children with infero-lateral TWI should remain under strict clinical surveillance. PMID- 30292436 TI - Chest pain in the absence of obstructive coronary artery disease: A critical review of current concepts focusing on sex specificity, microcirculatory function, and clinical implications. AB - Patients presenting with chest pain suggestive of coronary artery disease (CAD) who at coronary arteriography appear to be free of obstructive disease have presented a diagnostic and therapeutic challenge since the 1970's. Studies in female patient populations have suggested that this is predominantly a women's syndrome usually caused by microvascular endothelial dependent and independent dysfunction. A critical review of the literature focusing on studies including both women and men revealed that apart from a higher incidence of this syndrome in women there are no clinical relevant differences between both sexes. In women a lower coronary flow reserve has been reported but this appears to be mainly due to a higher basal flow. Important questions with regard to the clinical implications of microvascular dysfunction have yet to be resolved in studies involving women as well as men in which a distinction is made between patients with normal coronary arteries and those with nonobstructive disease. PMID- 30292437 TI - Using Bayesian methods to update and expand the meta-analytic evidence of the five-factor model's relation to antisocial behavior. AB - The Five Factor Model (FFM) of personality is the dominant hierarchical model of personality. Previous work has demonstrated the importance of the FFM domains and facets in understanding a variety of antisocial behaviors ranging from non violent antisocial behavior to a variety of aggression outcomes. The aim of the present meta-analysis was to quantitatively summarize the empirical work that has examined these relations, as well as update and expand previous work in this area using Bayesian meta-analytic methods. A comprehensive search of available literature on the FFM and antisocial behavior was conducted and posterior distributions of effect sizes were computed for the FFM domains (across 12 antisocial outcomes). The meta-analytic results supported the primary importance of (low) Agreeableness and (low) Conscientiousness in predicting antisocial behavior across antisocial outcomes, with the exception of the outcome related to child molestation. The importance of Neuroticism was more dependent on the specific antisocial outcome under examination. The results are discussed in the context of the descriptive research on the FFM and antisocial behavior, and how Bayesian methods provide additional utility in estimation and prediction compared to more common frequentist methods. Furthermore, we recommend that future work on the FFM and antisocial behavior move towards process-level analyses to further examine how traits are implicated in different forms of antisocial behavior. PMID- 30292438 TI - The psychology of Tourette disorder: Revisiting the past and moving toward a cognitively-oriented future. AB - Tourette syndrome is a neurodevelopmental disorder characterized by chronic tics (i.e., repetitive and stereotyped movements and vocalizations) and premonitory urges (i.e., aversive sensations preceding tics that are alleviated once a tic is performed). Research supports that dysfunctional neurobiological and psychological processes interact and contribute to the development and maintenance of tics. However, psychological theories of Tourette syndrome and accompanying research have mainly focused on the emotional states (e.g., anxiety and frustration) and behavioural principles (i.e., operant conditioning) that play a role in tic exacerbation. This selective review summarizes key discoveries pertaining to the emotional and behavioural aspects of Tourette syndrome but also proposes a more comprehensive, cognitively-oriented conceptualization of the disorder. Specifically, it is proposed that maladaptive beliefs about discomfort and about one's ability to cope with discomfort underlie negative appraisals of unpleasant sensory experiences in individuals with Tourette syndrome. It is further suggested that these beliefs lead individuals to perceive premonitory urges in a catastrophic manner and thereby enhance tic frequency. Concrete research avenues to empirically examine these hypotheses are outlined and clinical implications for the field of cognitive-behaviour therapy are discussed. PMID- 30292439 TI - Diversity in randomized clinical trials of depression: A 36-year review. AB - Historically, authors reporting the results of randomized clinical trials (RCTs) to address mental health problems have insufficiently described sample characteristics pertaining to the ethnic/racial, linguistic, socioeconomic, and immigrant backgrounds of participants. RCTs have also had inadequate representation of participants from diverse backgrounds. This study reports on the trends in the reporting and representation of various sample demographic characteristics in RCTs of psychotherapy and other psychosocial interventions for depression over a 36-year period, and on the extent to which ethnicity, in particular, is considered in the analyses of treatment effects. A total of 342 trials (85.1% comprised of adult samples), representing 61,283 participants, are summarized in the review. Reporting for ethnicity and socioeconomic indicators improved over time, and RCTs for depression have also increasingly included significant numbers of ethnic minority and low-income groups. However, trials are far more likely to exclude, rather than include, linguistic minorities, and have not enrolled a meaningful number of Asian American, Native Hawaiian/Pacific Islander, Native American/Native Alaskan and multi-ethnic participants. Finally, treatment effects are almost never presented separately across racial/ethnic groups and ethnicity moderation analyses are only sporadically conducted. These findings have implications for generalizability, policy, journal reporting guidelines, and dissemination and implementation.

AB - OBJECTIVES: Furosemide is essential in the management of patients with congestive heart failure, and provides important iatrogenic complications. We described the prescription of this treatment in general medicine, and tried to identify areas for optimizing its use. PATIENTS AND METHOD: We carried out a prospective inventory of the prescription of furosemide with the general practitioners of the universities of Bordeaux, between May 1, 2017 and July 30, 2017. RESULTS: We obtained data from 119 prescriptions of furosemide. The indications seemed well known, largely dominated by heart failure (67%) and its associated signs (24%). Clinical and biological follow-up (52%) and therapeutic education (42%) seemed relatively infrequent. CONCLUSIONS: Our study confirms the central role of the general practitioner in the prescription of furosemide, the predominant place of heart failure in its indications and the iatrogeny observed. We identified areas of optimization of the safety and effectiveness of the treatment. The reinforcement of training concerning heart failure and its treatments, a better communication between specialties, the implementation of reference systems dedicated to the prescription of furosemide and prescription support software seem promising.

AB - BACKGROUND: The number of older adults treated for ST-segment elevation myocardial infarction (STEMI) is increasing. Nevertheless, their treatment might not be as optimal as younger adults. This study sought to evaluate demographic evolution, clinical characteristics and in-hospital outcomes of patients of patients aged 75years-old or older treated by primary angioplasty for STEMI. METHODS: Retrospective study of all consecutive patients for STEMI between January 2012 and December 2017. Their clinical, biologic, echocardiographic and angiographic data, as well as in-hospital outcomes were collected and compared between two groups: younger and older than 75 year-olds. RESULTS: Five hundred and sixty-eight patients including 99 (17.4%) 75 year-old or older were included in the present study. Patients aged 75 or older had an increased delay of treatment between the time of the chest pain onset and revascularization (7.30+/ 1,16 vs 4.77+/-0,36hours, P=0.0391), they were more frequently treated with clopidogrel rather than more potent anti P2Y12 antiplatelet therapies (55.6% vs 24.8%, P<0.0001) and received less frequently anti-GP2B3A therapy (44.8% vs 23.2%, P<0.0001). There was a trend for increased in-hospital mortality in the older group, despite non statistically significant (4.04% vs 1.5%, P=0.0847). Older adults had a worse clinical status with decreased post-STEMI left ventricular ejection fraction (44.42+/-1,38 vs 49.07+/-0,49, P=0,0019). They were also less treated with drug-eluting stents (51.5% vs 73.9%, P<0.0001). CONCLUSION: Adults aged 75 years-old or older represent a subsequent proportion of patients admitted for STEMI. They had a worse initial clinical presentation associated with worse prognostic, as compared to younger adults. They experience delayed reperfusion therapy and suboptimal treatment as compared to younger adults. PMID- 30292444 TI - [Evaluation of the management of low-risk pulmonary embolism diagnosed in an emergency department. HoPE study (Home treatment of Pulmonary Embolism)]. AB - INTRODUCTION: Risk stratification allows outpatient management of low-risk pulmonary embolism (PE). Here, we carry out an evaluation of the professional practices on the emergency management of low-risk PE, after selection with the sPESI score. MATERIAL AND METHOD: All patients admitted to the emergency department of Chambery hospital, with a final diagnosis of PE are analyzed. The PE of score sPESI at 0 are included, in the absence of contraindications. Ninety day follow-up is done. The objective is to evaluate the proportion of ambulatory care for low-risk patients. RESULTS: Eighty PE were diagnosed in 2016, 28 with sPESI score at 0 and 3 patients excluded. Of the 25 inclusions, 6 patients had signs of right ventricular dysfunction and were therefore hospitalized. The remaining 19 were eligible for outpatient care but only 8 of them stayed less than 24hours in the hospital. DISCUSSION: The sPESI score is a decision support tool for outpatient management but should not be used alone. The search for right ventricular dysfunction seems important here. PMID- 30292445 TI - [Management and prognosis of pulmonary embolism associated with right heart thrombi: A prospective study at the University Hospital Yalgado Ouedraogo]. AB - OBJECTIVE: To describe the management and evolution of high risk of death pulmonary embolism associated with right heart thrombi. MATERIAL AND METHODS: We conducted a prospective cohort survey over a 54 month-period, from March 1st, 2012 to September 30th 2015. Were included all patients with pulmonary embolism and having high or intermediate-high risk of death. Patients were divided into two groups according to whether cardiac Doppler-echography found a thrombus in the right chambers or not (ICT+ vs. ICT-). The survival curves for the patients were obtained using the software STATA. RESULTS: The prevalence of pulmonary embolism associated with right heart thrombi was 4% in our study. Thrombi were mobile, straight localization in all cases. The ICT+group was characterized by a significantly higher proportion of congestive heart and chronic lung disease. The proportion of patients' thrombolysis was significantly higher in the ICT-group. In the ICT+group, thrombolysis significantly reduced mortality giving a 30-day survival of 80% against 20% among patients receiving only heparin. CONCLUSION: Pulmonary embolism associated with right heart thrombi including the atrium are not exceptional. These patients are at high risk of early death. Thrombolysis is significantly improving the mortality of pulmonary embolism associated with right sided heart thrombi. PMID- 30292446 TI - Microdeletion 22q11.2 syndrome: Does thymus incidental surgical resection affect its immunological profile? AB - BACKGROUND: The del22q11 syndrome patients present immunological abnormalities associated to thymus alterations. Up to 75% of them present cardiopathies and thymus is frequently removed during surgery. The thymectomy per se has a deleterious effect concerning lymphocyte subpopulations, and T cell function. When compared to healthy controls, these patients have higher infections propensity of variable severity. The factors behind these variations are unknown. We compared immunological profiles of del22q11.2 Syndrome patients with and without thymectomy to establish its effect in the immune profile. METHODS: Forty six del22q11.2 syndrome patients from 1 to 16 years old, 19 of them with partial or total thymectomy were included. Heart disease type, heart surgery, infections events and thymus resection were identified. Immunoglobulin levels, flow cytometry for lymphocytes subpopulations and TREC levels were determined, and statistical analyses were performed. RESULTS: The thymectomy group had a lower lymphocyte index, both regarding total cell count and when comparing age-adjusted Z scores. Also, CD3+, CD4+ and CD8+ lower levels were observed in this group, the lowest count in those patients who had undergone thymus resection during the first year of life. Their TREC level median was 23.6/MUL vs 16.1MUL in the non thymus group (p=0.22). No differences were identified regarding immunoglobulin levels or infection events frequencies over the previous year. CONCLUSION: Patients with del22q11.2 syndrome subjected to thymus resection present lower lymphocyte and TREC indexes when compared to patients without thymectomy. This situation may be influenced by the age at the surgery and the time elapsed since the procedure. PMID- 30292447 TI - Osteoprotegerin mediate RANK/RANKL signaling inhibition eases asthma inflammatory reaction by affecting the survival and function of dendritic cells. AB - INTRODUCTION: Asthma is a chronic inflammatory, heterogeneous airway disease affecting millions of people around the world. Dendritic cells (DCs) are considered the most important antigen-presenting cell in asthma airway inflammatory reaction. But whether osteoprotegerin (OPG) mediate RANK/RANKL signaling inhibition influences asthma development by affecting the survival and function of DCs remains unclear. In this study, we assessed the effects of OPG on DCs and asthma. MATERIAL AND METHODS: BALB/c mice immunized with ovalbumin (OVA) were challenged thrice with an aerosol of OVA every second day for eight days. Dexamethasone (1.0mg/kg) or OPG (50MUg/kg) was administered intraperitoneally to OVA-immunized BALB/c mice on day 24 once a day for nine days. Mice were analyzed for effects of OPG on asthma, inflammatory cell infiltration and cytokine levels in lung tissue. The expression of RANK and beta-actin was detected by Western Blot. DCs were isolated from mouse bone morrow. Cell survival was assessed by cell counting. The content of IL-12 was detected by ELISA. RESULTS: Results showed that OVA increased the number of inflammatory factors in BALF, elevated lung inflammation scores in mice. OPG reversed the alterations induced by OVA in the asthmatic mice. OPG inhibited the survival and function of DC via inhibition of RANK/RANKL signaling. CONCLUSIONS: This research proved inhibition of RANK/RANKL signaling by OPG could ease the inflammatory reaction in asthma, providing new evidence for the application of OPG on asthma. PMID- 30292448 TI - Widening the antimicrobial spectrum of esters of bicyclic amines: In vitro effect on gram-positive Streptococcus pneumoniae and gram-negative non-typeable Haemophilus influenzae biofilms. AB - Antibiotic resistance is a global current threat of increasing importance. Moreover, biofilms represent a medical challenge since the inherent antibiotic resistance of their producers demands the use of high doses of antibiotics over prolonged periods. Frequently, these therapeutic measures fail, contributing to bacterial persistence, therefore demanding the development of novel antimicrobials. Esters of bicyclic amines (EBAs), which are strong inhibitors of Streptococcus pneumoniae growth, were initially designed as inhibitors of pneumococcal choline-binding proteins on the basis of their structural analogy to the choline residues in the cell wall. However, instead of mimicking the characteristic cell chaining phenotype caused by exogenously added choline on planktonic cultures of pneumococcal cells, EBAs showed an unexpected lytic activity. In this work we demonstrate that EBAs display a second, and even more important, function as cell membrane destabilizers. We then assayed the inhibitory and disintegrating activity of these molecules on pneumococcal biofilms. The selected compound (EBA 31) produced the highest effect on S. pneumoniae (encapsulated and non-encapsulated) biofilms at very low concentrations. EBA 31 was also effective on mixed biofilms of non-encapsulated S. pneumoniae plus non-typeable Haemophilus influenzae, two pathogens frequently forming a self-produced biofilm in the human nasopharynx. These results support the role of EBAs as a promising alternative for the development of novel, broad range antimicrobial drugs encompassing both Gram-positive and Gram-negative pathogens. PMID- 30292449 TI - Implications of the transcription factor WT1 linked to the pathologic cardiac remodeling post-myocardial infarction. AB - New advances in the treatment of acute myocardial infarction involve novel signaling pathways and cellular progeny. In this sense, regeneration is a novel tool that would contribute to post-infarction physiological ventricular remodeling. More specifically, re-expression of the WT1 transcription factor in the myocardial wall by ischemia and infarction would be related to the invasion of cells with the capacity for regeneration. This mechanism seems not to be sufficient to restore muscle cells and lost vessels entirely. Of particular interest, the presence of the heat-shock response protein 70 (Hsp70) and its interaction with the vitamin D receptor would modulate the expression of WT1 positively. In this context, it is proposed that the activation of vitamin D receptors associated with Hsp70 could favor physiological cardiac remodeling and reduce the progression to heart failure. PMID- 30292450 TI - TRalpha inhibits arterial renin-angiotensin system expression and prevents cholesterol accumulation in vascular smooth muscle cells. AB - OBJECTIVES: The tissue renin-angiotensin system (tRAS) plays a key role in the maintenance of cellular homeostasis but is also implicated in atherosclerosis. Thyroid hormone (TH) contributes, via genomic effects, to control of tRAS gene expression in the arterial wall and vascular smooth muscle cells (VSMCs). We investigated the specific functions of TH receptors-alpha and -beta (TRalpha and TRbeta) on tRAS gene expression in the aorta and VSMCs, and the potential protective effect of TRalpha against atherosclerosis. MATERIAL AND METHODS: Using aorta and cultured aortic VSMCs from TRalpha and TRbeta deficient mice, tRAS gene expression was analyzed by determining mRNA levels on real-time PCR. Gene regulation under cholesterol loading mimicking atherosclerosis conditions was also examined in VSMCs in vitro. RESULTS: TRalpha deletion significantly increased expression of angiotensinogen (AGT) and angiotensin II receptor type 1 subtype a (AT1Ra) at transcriptional level in aorta, a tissue with high TRalpha expression level. TRalpha activity thus seems to be required for maintenance of physiological levels of AGTand AT1Raexpression in the arterial wall. In addition, during cholesterol loading, TRalpha deletion significantly increased cholesterol content in VSMCs, with a weaker decrease in AGTexpression. CONCLUSION: TRalpha seems to have an inhibitory impact on AGTand AT1Raexpression, and loss of TRalpha function in TRalpha0/0 mice increases tRAS expression in the aortic wall. More importantly, TRalpha deletion significantly increases VSMC cholesterol content. Our results are consistent with a protective role of TRalpha against atherosclerosis. PMID- 30292451 TI - Outcomes of Vital Pulp Therapy Using Mineral Trioxide Aggregate or Biodentine: A Prospective Randomized Clinical Trial. AB - INTRODUCTION: Mineral trioxide aggregate (MTA) has been used in pulp capping of cariously exposed mature permanent teeth with promising results. The search for alternative materials that seal better and set faster than MTA and do not stain is ongoing. Biodentine (Septodont, St Maur-des-Fosses, France) exhibits these advantages but has not been tested yet for a prolonged duration in mature teeth. This study aimed to evaluate the clinical performance of Biodentine and white MTA (Angelus, Londrina, Brazil) in cariously exposed mature permanent teeth. METHODS: This was a prospective longitudinal randomized controlled study of 68 vital permanent teeth with deep caries. Patients were randomly allocated into 2 study arms: Biodentine and MTA. Teeth were assessed clinically and radiographically before the procedure. Caries were excavated under local anesthesia; hemostasis was achieved after pulp exposure using sodium hypochlorite and capped with Biodentine or MTA. Clinical and radiographic follow-ups were performed by a blinded calibrated evaluator after 6 months and 1, 2, and 3 years. RESULTS: There were no significant differences in the overall success rate between Biodentine and MTA; it was 93.3% (Biodentine = 93.1% and MTA = 93.5%) at 6 months. The overall success rate increased to 96.2% (Biodentine = 96.0% and MTA = 100%) at 1 year and to 100% at 2 years. At the 3-year follow-up, it decreased to 93.8% (Biodentine = 91.7% and MTA = 96.0%). CONCLUSIONS: Biodentine and MTA have favorable and comparable success rates when used as direct pulp capping or pulpotomy material in permanent mature teeth with carious exposure. The remaining tooth structure and durability of coronal restoration might affect significantly the long-term success of vital pulp therapy. PMID- 30292452 TI - Lymphaticovenous bypass of the thoracic duct for the treatment of chylous leak in central conducting lymphatic anomalies. AB - BACKGROUND: Central conducting lymphatic anomalies (CCLA) may cause chylous leaks and protein-losing enteropathy (PLE) owing to dysfunction of the central lymphatic channels. Most of the treatment strategies for these conditions are palliative and provide transient improvement. METHODS: We treated 14 patients with intractable chylous leak and/or PLE using a novel technique of lymphaticovenous bypass of the terminal portion of the thoracic duct. Chylous leaks occurred in multiple different anatomic sites. All patients had CCLA and failure of thoracic duct emptying demonstrated by preoperative intranodal lymphangiography. RESULTS: Five patients had complete resolution of symptoms, and two patients had partial improvement. There were no major complications. Of 5 patients with PLE, only one improved after lymphaticovenous bypass. Repeat traditional lymphangiography was performed in 4 patients who did not improve, demonstrating patency of the bypass in all cases with persistent sluggish drainage. One patient had repeat MR lymphangiography that did not show the thoracic duct well. CONCLUSIONS: Bypass of the terminal thoracic duct is a novel procedure that offers improvement and a chance of cure for some patients with devastating manifestations of CCLA who lack other effective therapeutic options. LEVEL OF EVIDENCE: IV. PMID- 30292453 TI - Using Individual Clinical Evaluations to Assess Residents' Clinical Judgment; Feasibility and Residents' Perception. AB - OBJECTIVE: In surgical training, most assessment tools focus on advanced clinical decision-making or operative skill. Available tools often require significant investment of resources and time. A high stakes oral examination is also required to become board-certified in surgery. We developed Individual Clinical Evaluation (ICE) to evaluate intern-level clinical decision-making in a time- and cost efficient manner, and to introduce the face-to-face evaluation setting. DESIGN: Intern-level ICE consists of 3 clinical scenarios commonly encountered by surgical trainees. Each scenario was developed to be presented in a step-by-step manner to an intern by an attending physician or chief resident. The interns had 17 minutes to complete the face-to-face evaluation and 3 minutes to receive feedback on their performance. The feedback was transcribed and sent to the interns along with incorrect answers. Eighty percent correct was set as a minimum to pass each scenario and continue with the next one. Interns who failed were retested until they passed. Frequency of incorrect response was tracked by question/content area. After passing the 3 scenarios, interns completed a survey about their experience with ICE. SETTING: Beth Israel Deaconess Medical Center, an academic tertiary care facility located in Boston, Massachusetts. PARTICIPANTS: All first-year surgery residents in our institution (n = 17) were invited to complete a survey. RESULTS: All 2016-2017 surgical interns (17) completed the ICEs. A total of $171 (US) was spent conducting the ICEs, and an average of 17 minutes was used to complete each evaluation. In total, 5 different residents failed 1 scenario, with the most common mistake being: failing to stabilize respiration before starting management. After completing the 3 clinical scenarios, more than 90% of respondents agreed or strongly agreed that the evaluations were appropriately challenging for training level, and that the evaluations helped to identify personal strengths and weaknesses in skill and knowledge. The majority believed their knowledge improved as a result of the ICE and felt better prepared to manage these scenarios (88% and 76%, respectively). CONCLUSIONS: The ICE is an inexpensive and time efficient way to introduce interns to board type examinations and assess their preparedness for perioperative patient care issues. Common errors were identified which were able to inform educational efforts. ICEs were well accepted by residents. Next steps include extension of the ICE to PGY2 and PGY3 residents.

In this study, the benefits of using a new integrated video recording system, were investigated and compared to those of the standard basic skills robotic training procedure. DESIGN: Fifty residents from the 2nd and 3rd year medical faculty without any experience of robot usage or laparoscopy were randomized into 2 groups: group A--a natural self-training group without a trainer, and group B--a self-training group assisted by an integrated video recording system during training. The training was divided into four 2-hour sessions, with a 72-hour delay between each session. Two tasks were selected for testing on the dV-Trainer, a virtual reality based robotic simulator: Match board 2 and Thread the Rings 1. After each session, the practice video recorded by the system of group B was transferred to the residents' smartphones for self-debriefing. At the end of each session, the performance score was evaluated automatically by using the simulator to plot learning curves A and B. RESULTS: Group A showed a significant drop in performance score due to skill decay caused by the 72-hour delay. Group B exhibited a regular stepwise rising learning curve. At the end of the training, group B showed a significantly higher performance score both in Match board 2 and Thread the Rings 1. The autoanalysis and capture function, which selects only the critical errors and most valuable parts, could facilitate time saving. CONCLUSIONS: The use of an integrated video recording system makes the self-manipulated protocol with own smartphone feasible to improve training efficiency and overcome the skill decay during robotic surgical training.

AB - A comprehensive analysis of sequence variation was carried out comparing the fusion (F) protein of human respiratory syncytial viruses (hRSV) from antigenic groups A and B with the prototype sequence of the A2 strain, also belonging to antigenic group A. The limited number of full bovine RSV F sequences available were included, as well as an extensive set of F sequences from the related human metapneumovirus (hMPV). The results were analysed in the context of the recently determined three dimensional F protein structures, with antigenic sites mapped to these. Although a high degree of sequence conservation in hRSV F exists, and sequence changes did not correlate with location of antigenic sites, preferential accumulation of amino acid changes in certain antigenic sites was noted. When the analysis was extended to hMPV F, a high number of changes was noticed, in agreement with the limited degree of sequence conservation. However, some conserved regions were noted, which may account for the limited number of cross reactive monoclonal antibodies described between hRSV F and hMPV F. These results provide information about the degree of sequence and antigenic variation currently found in the F protein of circulating viruses. They highlight the importance of establishing a baseline dataset to monitor for future changes that might evolve should preventative immunological measures be made widely available.

AB - Routine immunization of infants with conjugate vaccines against Haemophilus influenzae type b (Hib) has greatly reduced the incidence of invasive Hib disease; however changes in the epidemiology of H. influenzae disease have occurred. We describe the epidemiology of invasive H. influenzae disease and the characterization of isolates collected in Italy between 2012 and 2016. Trends in the overall incidence of invasive H. influenzae disease were calculated. Isolates were characterized by PCR capsular genotyping, antimicrobial susceptibility testing, ampicillin resistance-associated gene sequencing and MLST. Trends in incidence by serotype and serotype-specific distribution were estimated using multiple imputation of missing data. The overall incidence of invasive H. influenzae disease increased 22.5% yearly (from 0.11/100,000 in 2012 to 0.24/100,000 in 2016). Most cases (82.0%) were due to non-typeable H. influenzae (NTHi). An increasing trend in NTHi disease burden was estimated; the highest rise was among infants <12 months (40.8% annual increase). Invasive Hib disease showed a fluctuating trend with a clear increase in 2016, while we found an increasing trend for disease due to non-Hib capsulated serotypes in the elderly (32.9% annual increase). Ampicillin resistance mediated by either beta-lactamase or altered penicillin-binding proteins 3 (PBP3) increased. In spite of genetic diversity of NTHi, sequence types (STs) associated with ampicillin resistance status were identified (ST103/ST106 linked to beta-lactamase production and ST14 linked to a specific PBP3 substitution pattern). The increasing trend in invasive NTHi disease in infants is of concern underlying the need for the development of a future vaccine against NTHi.

PMID- 30292460 TI - Comparison of Patient Position and Midline Lumbar Neuraxial Access Via Statistical Model Registration to Ultrasound. AB - Patient positioning and needle puncture site are important for lumbar neuraxial anesthesia. We sought to identify optimal patient positioning and puncture sites with a novel ultrasound registration. We registered a statistical model to volumetric ultrasound data acquired from volunteers (n = 10) in three positions: (i) prone; (ii) seated with thoracic and lumbar flexion; and (iii) seated as in position ii, with a 10 degrees dorsal tilt. We determined injection target size and penetration success by simulating lumbar injections on validated registered models. Injection window and target area sizes in seated positions were significantly larger than those in prone positions by 65% in L2-3 and 130% in L3 4; a 10 degrees tilt had no significant effect on target sizes between seated positions. In agreement with computed tomography studies, simulated L2-3 and L3-4 injections had the highest success at the 50% and 75% midline puncture sites, respectively, measured from superior to inferior spinous process. We conclude that our registration to ultrasound technique is a potential tool for tolerable determination of puncture site success in vivo.

AB - To evaluate the correlations between the enhancement pattern of intrahepatic cholangiocarcinoma (ICC) on contrast-enhanced ultrasound (CEUS) and clinicopathologic findings and prognosis, a retrospective study was performed on 197 patients with mass-forming ICC who underwent pre-operative CEUS and surgical resection. The contrast medium we employed in CEUS was SonoVue, which contains microbubbles consisting of sulfur hexafluoride bubbles within a phospholipid shell. This study was approved by the institutional review board with informed consent waived. Patients were classified into an arterial rim-like enhancement group or an arterial non-rim-like enhancement group, and arterial enhancement patterns were correlated with clinicopathologic factors. Overall survival (OS) times were calculated using the Kaplan-Meier method, and differences between groups were compared with the log-rank test. Univariate and multivariate Cox regression models for OS were used to evaluate the independent prognostic factors. The mean and range of ICC tumor size of the arterial rim-like group (59.41 +/- 22.09 mm, 20-100 mm) were similar to those of the arterial non-rim like group (59.82 +/- 30.35 mm, 14-162 mm, p = 0.914). Arterial enhancement patterns were correlated with chronic viral hepatitis or cirrhosis, vascular invasion, lymph node metastasis and single/multiple tumors. A total of 78 patients (39.6%) exhibited arterial rim-like enhancement, and the other 119 patients (60.4%) exhibited arterial non-rim-like enhancement. Arterial enhancement pattern (p = 0.045), vascular invasion (p = 0.005), lymph node metastasis (p = 0.000) and number of tumors (p = 0.001) were independent prognostic factors for OS. The arterial non-rim-like enhancement pattern of ICC on CEUS is an independent prognostic factor for better OS and may offer new information for predicting the prognosis of ICC patients before surgical resection. PMID- 30292462 TI - Non-linear Wave Propagation and Safety Standards for Diagnostic Ultrasound Devices. AB - Safety standards for clinical diagnostic ultrasonic devices were developed for use in relatively low-frequency systems (1-10 MHz), under the assumption that non linear effects would be negligible. This article reviews ways in which neglecting non-linear wave propagation affects the measurements and calculations required to comply with safety standards and U.S. Food and Drug Administration guidance that recognizes these standards. An attempt is made to evaluate whether ignoring non linear effects could result in significant error in the exposure quantities defined in these standards at either low or high frequencies, based on published literature. This article maintains that although non-linear effects have been considered in some parts of safety standards related to hydrophone requirements, the coverage is inadequate, especially for modern equipment with high working frequencies. A new approach is required to assess the magnitude of thermal heating for recently developed high-frequency systems to incorporate non-linear effects. In contrast, the current approach for evaluating the risk of cavitation can be used after appropriate modifications. PMID- 30292463 TI - Evolution of the antibiotic-resistance of microorganisms causing urinary tract infections: A 4-year epidemiological surveillance study in a hospital population. AB - BACKGROUND: Urinary tract infections (UTIs) are the leading cause of infection in hospitalised patients. In this study, we describe the most common pathogens involved in the development of UTIs in hospitalised patients, their antibiotic sensitivity profile and the activity evolution of antibiotics in standard use for treating these infections. METHODS: We retrospectively assessed the results of cultures and antibiograms from urine samples from adult patients hospitalised in the Hospital Complex Virgen de la Nieves (Granada, Spain) with a microbiological confirmation of UTI between January 2013 and December 2016. RESULTS: We identified 4,347 microorganisms (3,969 bacteria and 378 yeasts). During the 4years of the study, Escherichia coli was the most common species isolated in both sexes; however, 62.9% of the UTIs were caused by other microorganisms. The presence of multiresistant microorganisms such as Acinetobacterspp. (1.2%) and extended-spectrum beta-lactamase-producing enterobacteria (10.0%) and carbapenemase-producing enterobacteria (0.3%) were also relevant findings. Imipenem, piperacillin-tazobactam and fosfomycin presented activity rates above 80%, considering all causal microorganisms of UTI, while the other tested antibiotics presented activity rates below 70%. CONCLUSION: Imipenem and piperacillin-tazobactam were the most active antibiotics in hospital use, which makes them first-line antibiotics in the empiric treatment of UTIs in this healthcare setting. The use of other antibiotics should be limited to conditions of demonstrated or highly probable sensitivity.

PMID- 30292465 TI - Evaluating the Impact of the Venous Thromboembolism Outcome Measure on the PSI 90 Composite Quality Metric. AB - INTRODUCTION: Patient Safety Indicator (PSI) 90 is a composite measure widely used in federal pay-for-performance and public reporting programs. A component metric of PSI 90, venous thromboembolism (VTE) rate, has been shown to be subject to surveillance bias and not a valid measure for hospital quality comparisons. A study was conducted to examine how hospital PSI 90 scores would change if the VTE measure were removed from calculation of this composite measure. METHODS: Using 2014 Medicare inpatient claims data, PSI 90 scores were calculated with and without the VTE measure for 3,203 hospitals. Hospital characteristics obtained from the American Hospital Association Annual Survey and Centers for Medicare & Medicaid Services Payment Update Impact File were merged with PSI 90 scores. RESULTS: Removing the VTE outcome measure from the calculation of PSI 90 version 5.0 improved PSI 90 scores for 17.1% of hospitals but lowered scores for 20.8% of hospitals, while 62.1 % had no change in scores. Hospitals were more likely to improve on PSI 90 when the VTE measure was removed if they were larger (odds ratio [OR] = 1.60; 95% confidence interval [CI] = 1.00-2.58), were major teaching hospitals (OR = 1.76; 95% CI = 1.10-2.79), had greater technological resources (OR = 2.03; 95% CI = 1.40-2.94), or cared for sicker patients (OR = 1.12; 95% CI = 1.01-1.25). CONCLUSION: Inclusion of the surveillance bias-prone VTE outcome measure in the PSI 90 composite disproportionately penalizes larger, academic hospitals and those that care for sicker patients. Removal of the VTE outcome measure from PSI 90 should be strongly considered. PMID- 30292466 TI - Soft-tissue vascular malformations and tumors. Part 2: low-flow lesions. AB - Vascular malformations and tumors, also known as "vascular anomalies", comprise an extensive variety of lesions involving all parts of the body. Due to a lack of a complete understanding of the origin and histopathology of such lesions, this field has been traditionally obscured by the use of an unclear nomenclature. Knowledge of the classification and clinical and imaging characteristics of this group of lesions is paramount when managing these patients. The objective of this series of two articles is to review the current classification of vascular anomalies, to describe the role of imaging in their diagnosis, to summarize their distinctive histopathologic, clinical and imaging features, and to discuss the treatment options. High-flow lesions were discussed in the first article of this series. In this second article, we will focus on low-flow lesions, including complex syndromes with associated low-flow malformations. PMID- 30292467 TI - Soft-tissue vascular malformations and tumors. Part 1: classification, role of imaging and high-flow lesions. AB - Vascular malformations and tumors, also known as "vascular anomalies", comprise an extensive variety of lesions involving all parts of the body. Knowledge of their classification and imaging characteristics is paramount. Whereas hemangiomas are benign vascular tumors, characterized by cellular proliferation and hyperplasia; vascular malformations are not real tumors and characteristically exhibit normal endothelial turnover. Vascular malformations are classified according to the predominant vascular channel as arterial, capillary, venous, lymphatic, or mixed. Ultrasound and MRI are the main imaging modalities used in the diagnosis and classification of the vascular anomalies. In this series of two articles we review the classification of vascular anomalies, describe the role of imaging, summarize their distinctive histopathogenic, clinical and imaging features, and discuss the treatment options. On the first article we discuss the high-flow lesions, whereas the slow-flow lesions will be reviewed on the second. Complex syndromes with associated vascular tumors and malformations will be also presented. PMID- 30292468 TI - Metabolic effects of cardiovascular medication: Does it matter?

AB - Atherosclerosis is an inflammatory and multifaceted disorder resulting from the accumulation of lipid droplets and several types of immune cells, including macrophages, T and B lymphocytes in the arterial walls. A wide variety of macrophage subtypes with different functions is implicated in the development and progression of atherosclerotic lesions. The prevalence of specific macrophage subtypes, which is influenced by cytokines, mediators, and substances composing atherosclerotic lesions, has been suggested to be an appropriate indicator of transition from a stable to an unstable plaque phenotype. Thus, a better understanding of the mechanisms underlying the differentiation of macrophage subpopulations in relation to the plaque phenotype would help to develop novel approaches aiming at slowing-down the progression of atherosclerotic disease by modulating the polarization of these cells. In addition, many arms of the adaptative immune system, which are regulated by different subtypes of T and B lymphocytes, are involved in atherosclerosis progression and there is an increasing effort to identify immune-modulating therapies targeting either T or B cells with a potential anti-atherosclerotic impact. This paper summarizes the pathophysiology of atherosclerotic disease as it relates to the contribution from the immune system, reviewing the crucial role of macrophages, T and B lymphocytes.

PMID- 30292475 TI - Association between diet and measures of arterial stiffness in type 1 diabetes - Focus on dietary patterns and macronutrient substitutions. AB - BACKGROUND AND AIMS: Increased arterial stiffness contributes to diabetic vascular complications. We identified dietary factors related to arterial stiffness in individuals with type 1 diabetes, a population with high risk of cardiovascular disease. METHODS AND RESULTS: Altogether, 612 participants (40% men, mean +/- standard deviation age 45 +/- 13 years) completed a validated diet questionnaire and underwent measurements of arterial stiffness. Of these, 470 additionally completed a food record. Exploratory factor analysis was applied to identify dietary patterns from the diet questionnaires, and nutrient intakes were calculated from food record entries. Arterial stiffness was measured by applanation tonometry. Of the seven dietary factors formed, the factor scores of "Full-fat cheese and eggs" and "Sweet" patterns were negatively associated with measures of arterial stiffness. In the multivariable macronutrient substitution models, favouring carbohydrates over fats was associated with higher aortic mean arterial pressure and aortic pulse wave velocity. When carbohydrates were consumed in place of proteins, higher aortic pulse pressure, aortic mean arterial pressure, and augmentation index were recorded. Replacing energy from alcohol with proteins, was associated with lower aortic pulse pressure, aortic mean arterial pressure, and augmentation index. Relative distributions of dietary fatty acids were neutral with respect to the measures of arterial stiffness. CONCLUSION: The macronutrient distribution of the diet is likely to affect the resilience of the arteries. Our observations suggest that reducing energy intake from carbohydrates and alcohol may be beneficial. These observations, especially those dealing with dietary patterns, need to be confirmed in a longitudinal study.

AB - Angiogenesis is a highly regulated process orchestrated, in large part, by the vascular endothelial growth factor-A (VEGF-A) system of ligands and receptors. Considerable effort has been invested in finding optimal ways to modulate VEGF-A activity to treat disease, however, the mechanisms by which the various components interact remain poorly understood. This is in part because of the difficulty of analyzing the various interactions in an intercomparable manner. In the present study, we established conditions to allow for the detailed characterization of the molecular interactions between VEGF and its receptors and the co-receptor NRP-1 using surface plasmon resonance (SPR). We found that VEGF dissociated 25-times faster from its major signaling receptor, VEGF receptor-2 (VEGFR-2) than from its "decoy" receptor, VEGF receptor-1 (VEGFR-1). Using a systematic approach, we obtained kinetic parameters for each individual interaction under a consistent set of experimental conditions allowing for comparison between various receptors. The set of quantitative kinetic parameters and experimental conditions reported herein will provide valuable tools for developing comprehensive models of the VEGF system. PMID- 30292478 TI - Epidemiology of common resistant bacterial pathogens in the countries of the Arab League. AB - No uniformly organised collection of data regarding antimicrobial resistance has occurred in the countries of the Arab League. 19 countries of the Arab League have published data for antimicrobial susceptibility for the WHO priority organisms, and seven of 14 of these organisms are included in this Review (Escherichia coli, Klebsiella spp, Pseudomonas aeruginosa, Acinetobacter baumannii, Salmonella spp, Staphylococcus aureus, and Streptococcus pneumoniae). Although E coli and Klebsiella spp resistance to third-generation cephalosporins is common in all countries, with prevalence reaching more than 50% in Egypt and Syria, carbapenem resistance is emerging, albeit with a prevalence of less than 10%. Conversely, a large amount of carbapenem resistance has been reported for P aeruginosa and A baumannii across the Arab League, reaching 50% and 88% of isolates in some countries. As for Salmonella spp, the prevalence of fluoroquinolone resistance has exceeded 30% in several areas. With regards to the Gram-positive pathogens, the prevalence of meticillin resistance in S aureus is reported to be between 20% and 30% in most countries, but exceeds 60% in Egypt and Iraq. The prevalence of penicillin non-susceptibility among pneumococci has reached more than 20% in Algeria, Egypt, Morocco, Saudi Arabia, and Tunisia. These findings highlight the need for structured national plans in the region to target infection prevention and antimicrobial stewardship. PMID- 30292479 TI - Phage therapy 2.0: where do we stand?

AB - Mass azithromycin distribution is a core component of trachoma control programmes and could reduce mortality in children younger than 5 years in some settings. In this systematic review we synthesise evidence on the emergence of antimicrobial resistance after mass azithromycin distribution. We searched electronic databases for publications up to June 14, 2018. We included studies of any type (excluding modelling studies, surveillance reports, and review articles) on community-wide distribution of oral azithromycin for the prevention and treatment of trachoma that assessed macrolide resistance, without restrictions to the type of organism. We extracted prevalence of resistance from published reports and requested unpublished data from authors of included studies. Of 213 identified studies, 19 met inclusion criteria (12 assessed Streptococcus pneumoniae) and were used for qualitative synthesis. Macrolide resistance after azithromycin distribution was reported in three of the five organisms studied. The lack of resistance in Chlamydia trachomatis suggests that azithromycin might remain effective for trachoma programmes, but evidence is scarce. As mass azithromycin distribution for trachoma continues and is considered for other indications, ongoing monitoring of antimicrobial resistance will be required. PMID- 30292481 TI - Efficacy and tolerability of a cocktail of bacteriophages to treat burn wounds infected by Pseudomonas aeruginosa (PhagoBurn): a randomised, controlled, double blind phase 1/2 trial. AB - BACKGROUND: Wound infections are the main cause of sepsis in patients with burns and increase burn-related morbidity and mortality. Bacteriophages, natural bacterial viruses, are being considered as an alternative therapy to treat infections caused by multidrug-resistant bacteria. We aimed to compare the efficacy and tolerability of a cocktail of lytic anti-Pseudomonas aeruginosa bacteriophages with standard of care for patients with burns. METHODS: In this randomised phase 1/2 trial, patients with a confirmed burn wound infection were recruited from nine burn centres in hospitals in France and Belgium. Patients were eligible if they were aged 18 years or older and had a burn wound clinically infected with P aeruginosa. Eligible participants were randomly assigned (1:1) by use of an interactive web response system to a cocktail of 12 natural lytic anti P aeruginosa bacteriophages (PP1131; 1 * 106 plaque-forming units [PFU] per mL) or standard of care (1% sulfadiazine silver emulsion cream), both given as a daily topical treatment for 7 days, with 14 days of follow-up. Masking of treatment from clinicians was not possible because of the appearance of the two treatments (standard of care a thick cream, PP1131 a clear liquid applied via a dressing), but assignments were masked from microbiologists who analysed the samples and patients (treatment applied while patients were under general anaesthetic). The primary endpoint was median time to sustained reduction in bacterial burden by at least two quadrants via a four-quadrant method, assessed by use of daily swabs in all participants with a microbiologically documented infection at day 0 who were given at least one sulfadiazine silver or phage dressing (modified intention-to-treat population). Safety was assessed in all participants who received at least one dressing according to protocol. Ancillary studies were done in the per-protocol population (all PP1131 participants who completed 7 days of treatment) to assess the reasons for success or failure of phage therapy. This trial is registered with the European Clinical Trials database, number 2014-000714-65, and ClinicalTrials.gov, number NCT02116010, and is now closed. FINDINGS: Between July 22, 2015, and Jan 2, 2017, across two recruitment periods spanning 13 months, 27 patients were recruited and randomly assigned to receive phage therapy (n=13) or standard of care (n=14). One patient in the standard of care group was not exposed to treatment, giving a safety population of 26 patients (PP1131 n=13, standard of care n=13), and one patient in the PP1131 group did not have an infection at day 0, giving an efficacy population of 25 patients (PP1131 n=12, standard of care n=13). The trial was stopped on Jan 2, 2017, because of the insufficient efficacy of PP1131. The primary endpoint was reached in a median of 144 h (95% CI 48-not reached) in the PP1131 group versus a median of 47 h (23-122) in the standard of care group (hazard ratio 0.29, 95% CI 0.10-0.79; p=0.018). In the PP1131 group, six (50%) of 12 analysable participants had a maximal bacterial burden versus two (15%) of 13 in the standard of care group. PP1131 titre decreased after manufacturing and participants were given a lower concentration of phages than expected (1 * 102 PFU/mL per daily dose). In the PP1131 group, three (23%) of 13 analysable participants had adverse events versus seven (54%) of 13 in the standard of care group. One participant in each group died after follow-up and the deaths were determined to not be related to treatment. The ancillary study showed that the bacteria isolated from patients with failed PP1131 treatment were resistant to low phage doses. INTERPRETATION: At very low concentrations, PP1131 decreased bacterial burden in burn wounds at a slower pace than standard of care. Further studies using increased phage concentrations and phagograms in a larger sample of participants are warranted. FUNDING: European Commission: Framework Programme 7. PMID- 30292482 TI - Clinical outcomes of home parenteral nutrition patients using taurolidine as catheter lock: A long-term cohort study. AB - BACKGROUND & AIMS: Central venous access device (CVAD)-related complications, such as central-line associated bloodstream infections (CLABSIs), CVAD-related venous thromboses (CRVTs) and -occlusions frequently occur in home parenteral nutrition (HPN) patients. A preventive strategy to decrease the incidence of CLABSIs is the use of CVAD lock solutions, such as 2% taurolidine. The aim of this study was to evaluate long-term clinical outcomes of our HPN cohort while using taurolidine as lock solution. In addition, we explored risk factors associated with CVAD-related complications. METHODS: We conducted a retrospective analysis of complications (CLABSIs, CRVTs and CVAD occlusions) and adverse events in adult HPN patients while using taurolidine as lock solution. Patients with a benign underlying disease leading to intestinal failure were included between 2006 and 2017 at our tertiary referral centre for intestinal failure. Primary outcome was the effectiveness of taurolidine, as described by complication incidence rates. Secondary objectives were to assess adverse events of taurolidine, complication rates of patients who subsequently discontinued taurolidine and started using 0.9% saline alternatively, and risk factors associated with complications. RESULTS: In total, 270 HPN patients used taurolidine during 338521 catheter days. CLABSIs, CRVTs and CVAD occlusions occurred at a rate of 0.60 (CI95% 0.52-0.69), 0.28 (CI95% 0.23-0.34), and 0.12 (CI95% 0.08-0.16) events per 1000 catheter days, respectively. In 24 (9%) patients, mild to moderate adverse events resulted in discontinuation of 2% taurolidine. A subsequent switch to 0.9% saline resulted in an increased CLABSI rate (adjusted rate ratio 4.01 (95%CI 1.23-13.04), P = 0.02). Several risk factors were identified for CLABSIs (a lower age, nontunneled catheters, infusion frequency), CRVTs (site of vein insertion), and CVAD occlusions (type of CVAD). CONCLUSION: Complication rates remained low in the long-term, and use of taurolidine was generally safe. The identified risk factors may help to create new strategies to further prevent CVAD-related complications and improve HPN care in the future. PMID- 30292483 TI - Resting energy expenditure equations in amyotrophic lateral sclerosis, creation of an ALS-specific equation. AB - INTRODUCTION: Resting energy expenditure (REE) formulas for healthy people (HP) are used to calculate REE (cREE) in amyotrophic lateral sclerosis (ALS) patients. In 50-60% of ALS cases an increase of measured REE (mREE) in indirect calometry (IC) compared to cREE is found. The aims here were (i) to assess the accuracy of cREE assessed using 11 formulas as compared to mREE and (ii) to create (if necessary) a specific cREE formula for ALS patients. METHOD: 315 Patients followed in the ALS expert center of Limoges between 1996 and 2014 were included. mREE assessed with IC and cREE calculated with 11 predictive formulas (Harris Benedict (HB) 1919, HB 1984, WSchofield, De Lorenzo, Johnstone, Mifflin, WHO/FAO, Owen, Fleisch, Wang and Rosenbaum) were determined at the time of diagnosis. Fat free mass (FFM) and fat mass (FM) were measured with impedancemetry. A Bland and Altman analysis was carried out. The percentage of accurate prediction +/-10% of mREE, and intraclass correlation coefficients (ICC) were calculated. Using a derivation sample, a new REE formula was created using multiple linear regression according to sex, age, FFM and FM. Accuracy of this formula was assessed in a validation sample. RESULTS: ICC ranged between 0.60 and 0.71 (moderate agreement), and percentage of accurate prediction between 27.3% and 57.5%. Underestimation was found from 31.7% to 71.4% of cases. According to these unsatisfactory results we created an ALS-specific formula in a derivation sample (130 patients). ICC and percentage of accurate prediction increased in a validation sample (143 patients) to 0.85 (very good agreement) and 65.0% respectively, with 17.5% underestimation. CONCLUSION: REE formulas for HP underestimate REE in ALS patients compared to mREE. Our new ALS-specific formula produced better results than formulas for HP. This formula can be used to estimate REE in ALS patients if IC is not accessible. PMID- 30292484 TI - Anaesthetic strategy during endovascular therapy. PMID- 30292485 TI - Cranial nerves VII and XII palsy after shoulder surgery. AB - A 46-year-old man underwent a left shoulder surgery in the beach chair position with general anaesthesia and oro-tracheal intubation preceded by a left interscalenic block. Patient's head was attached to the headrest in a position of soft extension and moderate right rotation with adhesive tape surrounding his forehead and mandible. Surgery was marked by repeated vertical tractions on the left arm and by blood resorption of the arthroscopy's irrigation fluid, including epinephrine, which translated in a heart rate and arterial blood pressure rise. Upon waking the patient had severe headaches, left Horner's sign, left facial paresis and a left lingual paralysis. MRI and CT scan did not show any carotid dissection or parapharyngeal lesion. Electromyogram and neurological examination confirmed a VII and XII cranial nerve peripheral lesion, which took several months to regress. An ischaemic complication was suspected although the most probable cause of the patient's symptoms was subsequent to an Eagle's syndrome neurapraxia related to a long styloid process.

AB - Through this series of four closed claims, we highlight examples of accidents stemming from poor ventilator use. We then review the main issues in this regard as reported in the literature and by learned societies. This case series has led us to emphasise the need for safety procedures involving systematic checks prior to use, declaration and analysis of the risk, as well as feedback and teaching regarding ventilation systems. PMID- 30292489 TI - The impact of lipids, lipid oxidation, and inflammation on AMD, and the potential role of miRNAs on lipid metabolism in the RPE. AB - The accumulation of lipids within drusen, the epidemiologic link of a high fat diet, and the identification of polymorphisms in genes involved in lipid metabolism that are associated with disease risk, have prompted interest in the role of lipid abnormalities in AMD. Despite intensive investigation, our understanding of how lipid abnormalities contribute to AMD development remains unclear. Lipid metabolism is tightly regulated, and its dysregulation can trigger excess lipid accumulation within the RPE and Bruch's membrane. The high oxidative stress environment of the macula can promote lipid oxidation, impairing their original function as well as producing oxidation-specific epitopes (OSE), which unless neutralized, can induce unwanted inflammation that additionally contributes to AMD progression. Considering the multiple layers of lipid metabolism and inflammation, and the ability to simultaneously target multiple pathways, microRNA (miRNAs) have emerged as important regulators of many age related diseases including atherosclerosis and Alzheimer's disease. These diseases have similar etiologic characteristics such as lipid-rich deposits, oxidative stress, and inflammation with AMD, which suggests that miRNAs might influence lipid metabolism in AMD. In this review, we discuss the contribution of lipids to AMD pathobiology and introduce how miRNAs might affect lipid metabolism during lesion development. Establishing how miRNAs contribute to lipid accumulation in AMD will help to define the role of lipids in AMD, and open new treatment avenues for this enigmatic disease. PMID- 30292490 TI - Expression of retinoic acid signaling components ADH7 and ALDH1A1 is reduced in aniridia limbal epithelial cells and a siRNA primary cell based aniridia model. AB - PAX6-related Aniridia is a sight-threatening disease involving progression of secondary glaucoma and aniridia related keratopathy (ARK). Change or loss of limbal epithelial progenitors causes epithelial surface defects. We analyzed the effect of PAX6 on mRNA expression changes with a two-step approach, as follows. First, we sequenced mRNA from limbal epithelial cells isolated from controls and aniridia patients. Second, we confirmed the bioinformatics and literature-based result list for a small interfering RNA (siRNA)-based primary aniridia cell model (PAX6 knockdown). With this approach, we expected that the genes directly influenced by PAX6 would be distinguishable from those affected secondarily by the ARK disease state. Therefore, epithelial cells were isolated from the limbus region of two patients with aniridia and cultured in keratinocyte serum-free medium. Normal control cells were obtained from the limbus region of corneal donors. For the siRNA-based aniridia cell model, cells were transfected with Lipofectamine and 5 nM siRNA against PAX6 or control treatment. All cells were lysed to yield DNA, RNA, and protein. Reduction of PAX6 protein was assessed by western blot. Aniridia and control Poly-A-enriched RNA libraries were subjected to next-generation sequencing. The differential analysis was a combination of quantification with RSEM and differential tests with edgeR. Gene lists were filtered by comparison to NCBI GEO datasets, annotated with DAVID, and manually annotated using a literature search. Based on the resulting filtered gene list, qPCR primers were purchased, and candidate genes (TP63, ABCG2, ADH7, ALDH1A1, PITX1, DKK1, DSG1, KRT12, KRT3, KRT13, SPINK6, SPINK7, CTSV, SERPINB1) were verified by qPCR on the siRNA-based aniridia cell model. We identified genes that might be regulated by PAX6 and showed that SPINK7 mRNA, which codes for a protease inhibitor, is downregulated in patients as well as in our primary aniridia cell model. ALDH1A1 and AHD7 mRNA levels were reduced in limbal epithelial cells of aniridia patients, and both transcripts were downregulated by PAX6 knockdown in our cell model. This siRNA-based aniridia cell model is a valuable tool for confirming identified PAX6-affected genes that might promote ARK pathogenesis. The model recapitulated expression changes for SPINK7, ADH7, and ALDH1A1 that were also observed in patient samples. These results provide evidence that PAX6 might drive corneal epithelial differentiation by direct or indirect control of retinoic acid signaling processes through ADH7 and ALDH1A1. PMID- 30292491 TI - Antenatal Detection of Treatable Critical Congenital Heart Disease Is Associated with Lower Morbidity and Mortality. AB - OBJECTIVE: To establish the impact that timing of diagnosis and place of birth have on neonatal outcomes in those with readily treatable critical congenital heart disease. STUDY DESIGN: This was a population-based study with a complete national cohort of live-born infants with transposition of the great arteries and aortic arch obstruction in New Zealand between 2006 and 2014. Timing of diagnosis, place of birth, survival to surgery, in-hospital events, and neonatal mortality were reviewed. Live births with a gestation of >=35 weeks and without associated major extracardiac anomalies were included for analysis. RESULTS: A total of 166 live-born infants with transposition of the great arteries and 87 with aortic arch obstruction were included. Antenatal detection increased from 32% in the first 3 years to 47% in the last 3 years (P = .05). During the same period, neonatal mortality decreased from 9% to 1% (P = .02). No deaths occurred after surgical intervention. An antenatal diagnosis was associated with decreased mortality (1/97 [1%] vs 11/156 [7%]; P = .03) and birth outside the surgical center was associated with increased risk of mortality (11/147 [7%] vs 1/106 [1%]; P = .02). Those with an antenatal diagnosis required fewer hours of mechanical ventilation (P = .02) and had shorter durations of hospital stay (P = .05) compared with those diagnosed >48 hours after birth. CONCLUSIONS: The mortality risk for transposition of the great arteries and critical aortic arch obstruction is greatest before cardiac surgery. Improved antenatal detection allowing delivery at a surgical center is associated with reduced mortality. PMID- 30292493 TI - Fentanyl test strips as an opioid overdose prevention strategy: Findings from a syringe services program in the Southeastern United States. AB - BACKGROUND: In 2016, the number of overdose deaths involving illicitly manufactured fentanyl (IMF) surpassed heroin and prescription opioid deaths in the United States for the first time, with IMF-involved overdose deaths increasing more than 500% across 10 states from 2013 to 2016. IMF is an extremely potent synthetic opioid that is regularly mixed with heroin and often sold to unwitting consumers. Community-based organizations have started to distribute fentanyl test strips (FTS) as a strategy to identify IMF in street purchased products. We investigated the association between FTS use and changes in drug use behavior and perceived overdose safety among a community-based sample of people who inject drugs (PWID) in the United States. METHODS: Between September-October 2017, a total of 125 PWID completed an online survey about their most recent FTS use in Greensboro, North Carolina. Our first outcome of interest included whether PWID engaged in any of the following changes in drug use behavior after using FTS: used less than usual, administered tester shot, pushed syringe plunger slower than usual, and snorted instead of injected. Our second outcome of interest was whether PWID felt that FTS use made them feel better able to protect themselves from overdose. We conducted bivariate and multivariate analyses to determine the association between FTS use and these two outcomes. RESULTS: Overall, 63% of the sample reported a positive FTS test result and 81% reported using FTS prior to consuming their drugs. For the outcomes, 43% reported a change in drug use behavior and 77% indicated increased perceived overdose safety by using FTS. In multivariable models adjusting for demographic and FTS correlates, PWID with a positive FTS test result had five times the odds of reporting changes in drug use behavior compared to those with a negative result. PWID who used the FTS after drug consumption were 70% less likely to report behavioral changes at subsequent drug consumption compared to those who used it before consumption. PWID who were not existing clients of the syringe services program had four times higher odds than existing clients to report increased overdose safety from using FTS. CONCLUSIONS: We found that using FTS and receiving a positive test result was associated with changes in drug use behavior and perceptions of overdose safety. FTS may represent an effective addition to current overdose prevention efforts when included with other evidence-based strategies to prevent opioid overdose and related harm. PMID- 30292494 TI - National survey of fiducial marker insertion for prostate image guided radiotherapy. AB - INTRODUCTION: In the United Kingdom fiducial marker IGRT is the second most common verification method employed in radical prostate radiotherapy yet little evidence exists to support centres introducing or developing this practice. We developed a survey to elicit current fiducial marker practices adopted in the UK, to recommend standardisation of practice. METHODS: A 16 question survey was distributed across UK Radiotherapy centres via promotion at the British Uro Oncology Group Conference, 2016. Included were questions relating to workforce planning, patient preparation, insertion procedure and verification methods. The survey was open from September 2016 to January 2017. RESULTS: Results from 15 centres routinely inserting fiducial markers for prostate IGRT are presented. Eleven professional groups insert fiducial markers across the UK. Fourteen centres insert fiducial markers trans-rectally; one trans-perineally. Centres adopting a trans-rectal approach administer prophylactic ciprofloxacin as a single agent or combined with gentamicin or metronidazole; poor agreement between regimes presented. One centre has introduced targeted antibiotic prophylaxis. Five brands of fiducial markers are utilised nationally. Fourteen centres standardly insert three single fiducial markers, two common configurations emerged. Coupled fiducial markers are routinely implanted by one centre. All centres delay at least one week between fiducial marker insertion and planning CT; seven centres wait two weeks. The most common fiducial verification method is two-dimensional, paired kilo Voltage imaging. CONCLUSION: Variation in fiducial marker practice across the UK is considerable. Standardisation is required to support centres and healthcare professionals developing this service. Seven recommendations, to unify practice, have been proposed based on survey results and literature. PMID- 30292495 TI - Magnetic Resonance Imaging of synovitis in knees of patients with osteoarthritis without injected contrast agents using T1 quantification. AB - INTRODUCTION: To measure the range of T1 values of synovitis using three Tesla (3 T) magnetic resonance imaging (MRI) in patients with osteoarthritis to assess the potential of T1 mapping for identifying synovitis from other features in the knee on unenhanced magnetic resonance scans. METHODS: After receiving institutional ethical approval, 83 patients who met the American College of Rheumatology criteria for diagnosis of osteoarthritis of the knee were scanned using a 3 T Magnetic Resonance Imaging scanner. T1 maps were calculated from spoiled gradient echo images acquired with five different flip angles of 5 degrees -25 degrees . Mean values for the T1 measurements were calculated and compared to existing data from the published literature for anatomical and pathological structures of the knee. RESULTS: T1 values recorded in patients suffering from osteoarthritis demonstrated that T1 values for synovitis (confirmed on gadolinium enhanced images) fall in a narrow range (849-1277 ms, mean 1005 ms SD 91) delineating this from other structures of the knee such as muscle (T1 value range 1305-2638 ms, mean 1785 ms SD 304) and synovial fluid (T1 value range 3867-4129 ms, mean 3915 SD 899) at 3 T. CONCLUSION: T1 values measured in synovitis in patients with osteoarthritis of the knee demonstrated a range of values distinct to those measured in muscle and synovial fluid at 3 T. This offers potential for the use of T1 maps to delineate or quantify synovitis in patients who are unwilling or unable to receive injectable contrast agents. PMID- 30292496 TI - Embedding consultant radiographer roles within radiology departments: A framework for success. AB - INTRODUCTION: Many organisations struggle to clearly differentiate the radiographer consultant role from advanced or specialist practice, with newly appointed consultant practitioners often ill-prepared for working at this level. This article discusses the design, implementation and validation of an outcomes framework for benchmarking competencies for trainee or new-in-post consultant radiographers. METHODS: Five experienced radiographers from different clinical specialisms were seconded to a twelve month consultant trainee post, guided by a locally-devised outcomes framework. A longitudinal qualitative study explored, from the radiographers' perspective, the impact of the outcomes framework on the transition to consultant practice and beyond. Data collection included semi structured interviews (months 1, 6 and 12), validation via a focus group (month 18) and a group interview (5 years). RESULTS: Early interactions with framework objectives were mechanistic, but as participants better understood the role more creative approaches emerged. Despite diverse clinical expertise, the framework facilitated parity between participants, promoting transparency and credibility which was important in how the consultant role was perceived. All participants achieved all framework outcomes and were subsequently appointed to substantive consultant radiographer positions. CONCLUSION: This outcomes framework facilitates experienced radiographers to successfully transition into consultant radiographers, enabling them to meet multiple non-clinical targets while continuing to work effectively within a changing clinical environment. It is the first validated benchmarking tool designed to support the transition to radiographer consultant practice. Adoption of the tool will provide a standardised measure of consultant radiographer outcomes that will promote inter organisational transferability hitherto unseen in the UK. PMID- 30292497 TI - TRUFU: Therapeutic radiographer undertaking follow up for prostate cancer patients. AB - INTRODUCTION: A study was proposed to examine the impact to patients and the Oncology review team, of extending the role of the Therapeutic Radiographer to undertake follow up review of prostate cancer patients who have completed a radical course of external beam radiotherapy treatment. METHOD: A total of 30 patients attending for routine radiotherapy follow up were included in an observational study. Patients were assigned for review with a Doctor or a Therapeutic Radiographer using 1:1 randomisation and a number of time points were recorded and analysed. RESULTS: Of the 44 patients screened, 30 patients were recruited. Average time from scheduled appointment time to departure from clinic was 36 min for both the doctor and Therapeutic Radiographer. The average length of Consultation was 19 min for the Therapeutic Radiographer and 10 min for the Doctor. Average length of wait for patients from scheduled appointment time to being taken for review was 17 min for the Therapeutic Radiographer and 25 min for the Doctor. Of the patients who completed questionnaires, 23/28 had no preference of reviewer, 2/28 declared a preference to be seen by a doctor, whilst 3/28 stated a preference for review with a Therapeutic Radiographer. CONCLUSION: The results of the study are encouraging and should be further investigated in an attempt of developing what would be a very rewarding aspect of the Therapeutic Radiographers role. PMID- 30292498 TI - Running water sound technique in contrast-based voiding cystourethrogram: A case control study. AB - BACKGROUND: An intervention that can reduce the patient void time during a voiding cystourethrogram (VCUG) procedure can reduce the total radiation dose to the patient. This is because a delay in voiding leads to a high number of intermittent screenings to monitor if voiding occurs. This study assessed the impact of running-water sound (RWS) upon patients' voiding parameters and fluoroscopy screening times during VCUG examinations among children and adults. MATERIALS AND METHODS: A case-control study involving 252 patients was undertaken which consisted two groups (control and test) of adults and children. The test groups underwent VCUG with RWS technique while the control groups underwent the procedure normally. T-test was used to compare the study parameters between the two groups and a p-value less than 0.05 was interpreted as significant. RESULTS: The mean screening times (s) for children who underwent VCUG with and without RWS were 17.15 +/- 2.5s and 30.61 +/- 5.1s respectively (p = 0.0024). For adults, the RWS technique recorded a mean screening time of 37.36 +/- 4.4s while the non-RWS procedures recorded 49.80 +/- 5.2s (p = 0.001). The participants who received RWS intervention also felt the urge to void earlier than those who received no RWS intervention. The differences were also statistically significant for both children and adults. CONCLUSION: The study being one of the first in this subject area indicates that the application of RWS technique induces early urge of iodinated-contrast voiding, and reduces voiding and fluoroscopy screening times during VCUG among children and adults. This simple technique can potentially enhance current practice. PMID- 30292499 TI - Breast compression techniques in screening mammography - A Maltese evaluation project. AB - INTRODUCTION: In screening mammography, the radiographer should be responsible for providing mammograms of high diagnostic value, possibly without subjecting clients to a painful experience. This skill is demonstrated via the technique of breast compression and is explored in this study by analysing insights about methods and underlying principles in regards to this procedure. METHODS: One-to one semi-structured interviews were conducted with radiographers who perform screening mammography in Malta. For data analysis, a descriptive phenomenological approach following a simplified version of Hycner's (1985) method was adopted. RESULTS: Five general themes were extracted from the data; meeting the client, preparing the client, the mammography procedure, pain from compression and client turnout. It was determined that the participants alter their breast compression technique according to the client rather than following a rigid step-by-step process and that explanation and requesting client feedback are essential to obtain cooperation. Additionally, mammography positioning and compression application are tailored in a way that encourage compliance, however not at the expense of degrading image quality. Ultimately, it is also believed that a proper breast compression technique positively influences client turnout. CONCLUSION: The results of this study demonstrate that radiographers should be flexible in their approach in order to carry out a successful breast compression technique. However, it has also been shown that such effectiveness in practice is gained from experience rather than initial training. If exposed to this study's findings, new mammographers would be able to form a robust core of knowledge before embarking on the challenging specialisation of mammography. PMID- 30292500 TI - An evaluation of online information available for women with breast implants aged 47-73 who have been invited to attend the NHS Breast Screening Programme. AB - INTRODUCTION: The Internet has become an innovative instrument older adults utilise to obtain health-related information. Poor quality health information may cause harm to individuals. If not accessible, or at a level comprehended by target audiences, this does not support the development of their knowledge and subsequently hinders patient's ability to make informed-decisions. AIM: evaluate quality, readability, accessibility and usability of online information for women with breast implants invited to attend the NHSBSP. METHODS: Eight websites were evaluated for quality and accessibility/usability using uniquely developed evaluation tools. The 'three-click' rule was used to assess usability and SMOG tool to measure readability. Quality and accessibility/usability scores were combined to give an overall score, which were then converted into percentages. A percentage categorisation system ranked the percentage scores from poor to excellent. Readability scores were represented in number of years of education required to read/understand text. RESULTS: Average quality score = 14 (66.6%). Average accessibility/usability score = 9 (56.6%). 7 websites achieved an overall score in the poor percentage category (below 75%). Over 50% of websites had readability levels higher than the recommended level for online health information. 100% were above the UK average reading age. CONCLUSION: Websites providing information on breast screening with implants are not easily accessible, are of poor quality and too difficult to be read by most people. The quality, readability and accessibility of each website's content should be improved to help support women make informed decisions relating-to breast screening attendance, increase their understanding and lessen their anxiety. PMID- 30292501 TI - A questionnaire study of radiography educator opinions about patient lead shielding during digital projection radiography. AB - BACKGROUND: In projection radiography, lead rubber shielding has long been used to protect the gonads both within and outside the collimated field. However, the relative radio-sensitivity of the gonads is considered lower than previously, and doses from digital projection radiography are reported as being lower than in previous eras. These factors, along with technical difficulties encountered in placing lead shielding effectively, lead to varied opinions on the efficacy of such shielding in peer reviewed literature. This current study has investigated what is currently being taught as good practice concerning the use of lead shielding during projection radiography. METHOD: An online questionnaire was distributed to a purposive sample of 44 radiography educators across 15 countries, with the aim of establishing radiography educators' opinions about patient lead shielding and its teaching. RESULTS: From the 27 responding educators, 57% (n = 15) teach students to apply gonadal shielding across a range of radiographic examinations; only 22% (n = 6) do the same for the breast, despite respondents being aware that the breast has higher relative radio sensitivity than the gonads. Radiation protection was the primary reason given for using shielding. Students are generally expected to apply patient lead shielding during assessments, although a small number of respondents report that students must justify whether or not to apply lead shielding. Educators generally held the opinion that no matter what they are taught, students are influenced by what they see radiographers do in clinical practice. CONCLUSIONS: The current study has not found consensus in literature or in radiography educators' opinions concerning the use of patient lead shielding. Findings suggest that a large scale empirical study to establish a specific evidence base for the appropriate use of lead shielding across a range of projection radiography examinations would be useful. PMID- 30292502 TI - Assessment of isocenter alignment during CT colonography: Implications for clinical practice. AB - INTRODUCTION: Optimization of image quality and patient radiation dose is achieved in part by positioning the patient at the isocenter of the CT gantry. The aim of this study was to establish whether there was increased isocenter misalignment (IM) in CT colonography (CTC) scans by comparing patient position during the prone part of a CTC to patient position during renal stone protocol CT (CT-KUB) and patient position during the supine part of a CTC to patient position during abdominopelvic CT (CT-AP). METHODS: Two hundred and twenty two consecutive outpatient adult CTC studies performed between January and December 2016 were retrospectively analyzed. Automated dose-tracking software was used to quantify IM in the x and y planes. Renal stone CT-KUB (n = 100) and standard CT-AP (n = 100) were used as comparison studies. RESULTS: IM during CTC was significantly greater in the y-axis compared with the x-axis for both prone (p = 0.002) and supine (p < 0.001) scanning. IM was significantly greater during prone CTC compared with CT-KUB (p = 0.008) and during supine CTC compared with CT-AP (p = 0.0001). IM was shown to be slightly greater in studies performed by more experienced radiographers (p = 0.04). IM was not associated with patient age, gender or size (p > 0.05 for all). CONCLUSION: Isocenter misalignment is greater during CT colonography compared with CT-KUB or CT-AP. Strategies for improving patient positioning could include radiographer education and automated patient centering solutions. PMID- 30292503 TI - The detection of wooden foreign bodies: An experimental study comparing direct digital radiography (DDR) and ultrasonography. AB - INTRODUCTION: This experimental study compares the appropriateness of direct digital radiography (DDR) and ultrasonography at detecting soft-tissue wooden foreign bodies (FBs) in extremities. METHODS: Varying wooden FB splinters (2 mm, 5 mm and 10 mm) were inserted into eight porcine feet to simulate a patient presenting with a soft-tissue FB injury. Each of the FBs was placed in muscle distant, behind and near bone in the porcine feet. Control groups were used to check for false-positive diagnoses and, based on the presence of FBs; images were given a score depending on the level of visibility by the researcher. RESULTS: A higher detection rate was achieved for all FBs in muscle distant from bone using ultrasound. All of the 2 mm and 5 mm wooden FBs were not detected using DDR. The sensitivity in detecting the FBs was 5.8% and 30% in DDR and ultrasound respectively. CONCLUSION: Poor sensitivities and specificities were identified in this study. However, this study shows that ultrasound remains superior to DDR at identifying small foreign body objects. This study demonstrates that ultrasound can be a clinically effective tool for detecting suspected wooden FBs >5 mm in the foot and thus should be considered as the primary imaging modality of choice for referring clinicians. PMID- 30292504 TI - A phantom study of the performance of model-based iterative reconstruction in low dose chest and abdominal CT: When are benefits maximized? AB - INTRODUCTION: The aim of this study was to assess and compare the effects of CT image reconstruction techniques on low-dose CT image quality using phantoms. METHODS: Anthropomorphic torso and spatial/contrast-resolution phantoms were scanned at decreasing tube currents between 400 and 10 mA. CT thorax and abdomen/pelvis series were reconstructed with filtered back projection (FBP) alone, combined 40% adaptive statistical iterative reconstruction & FBP (ASIR40), and model-based iterative reconstruction (MBIR) [(resolution-preference 05 (RP05) and RP20 in the thorax and RP05 and noise-reduction 05 (NR05) in the abdomen)]. Two readers rated image quality quantitatively and qualitatively. RESULTS: In thoracic CT, objective image noise on MBIR RP05 data sets outperformed FBP at 200, 100, 50 and 10 mA and outperformed ASIR40 at 50 and 10 mA (p < 0.001). MBIR RP20 outperformed FBP at 50 and 10 mA and outperformed ASIR40 at 10 mA (p < 0.001). Compared with both FBP and ASIR40, MBIR RP05 demonstrated significantly better signal-to-noise ratio (SNR) at 10 mA. In abdomino-pelvic CT, MBIR RP05 and NR05 outperformed FBP and ASIR at all tube current levels for objective image noise. NR05 demonstrated greater SNR at 200, 100, 50 and 10 mA and RP05 demonstrated greater SNR at 50 and 10 mA compared with both FBP and ASIR. MBIR images demonstrated better subjective image quality scores. Spatial resolution, low-contrast detectability and contrast-to-noise ratio (CNR) were comparable between image reconstruction techniques. CONCLUSION: CTs reconstructed with MBIR have lower image noise and improved image quality compared with FBP and ASIR. These effects increase with reduced radiation exposure confirming optimal use for low-dose CT imaging. PMID- 30292505 TI - Undergraduate use of medical radiation science mobile applications. AB - INTRODUCTION: Despite the technologically intense nature of the medical radiation science (MRS) profession, literature specifically supporting the adoption of mobile learning in MRS education is scarce. To this aim, we explored student utilization of and influences for choosing MRS applications (apps, a specific type of mobile learning) within the Bachelor of Medical Radiation Science course at Charles Sturt University (CSU), Australia. Secondary objectives briefly investigated content reliability within selected chosen apps and overall student willingness to embrace this methodology prior to mainstream integration. METHODS: A mixed-method census survey was delivered to 415 enrolled students using the software Survey Monkey to compile responses to 28 questions. Inclusion criteria included students who owned a smartphone or tablet and who used any apps listed on the survey. RESULTS: Among the 97 students who completed the survey, 37% (36/97) freely use MRS apps at least weekly (70%, 21/30), of which anatomy atlases were reported as most popular. Peer recommendation influenced 67% (20/30) of students to choose the MRS apps used. Thirty-seven percent (11/30) of students integrated only one method to check the accuracy of app content prior to download. Students who do not use MRS apps (78%, 76/97) stated they were unaware of this resource; however, 91% (80/88) of the respondents indicated they would use MRS apps if incorporated into the curriculum. CONCLUSION: The majority of CSU students agreed that apps offer a convenient way to engage in a variety of interactive content both in the classroom and on-the-go, using apps most pertinent to their specific curriculum and/or for revision. Students preferred to use MRS apps if integrated as supplemental study tools vetted by the lecturer. PMID- 30292506 TI - Barriers and incentives for choosing to specialise in mammography- A survey of Australian undergraduate diagnostic radiography students. AB - INTRODUCTION: There is a projected shortage of radiographers working in breast screening in Australia. This study aimed to examine the perceived barriers and potential incentives among current undergraduate diagnostic radiography students to train, specialise and work in mammography. METHODS: A survey was undertaken to assess students' experience of six modalities during both University study and clinical practice. Students were asked to rank their priority of which they would want to specialise and if training and working in mammography was an option. RESULTS: From 248 students invited to participate, 101 students replied to the survey. Students indicated that they had been taught all modalities, however not all students had experienced them on clinical placement. Most students had observed or performed ultrasound (US) (90%, 90%), Computed Tomography (CT) (97%, 75%) and fluoroscopy (80%, 52%), though very few had experience of mammography (55%, 8%). US, CT, and MRI were the modalities that most students would like to specialise in. Male students reported being discriminated against working in mammography as this is "female only" work. CONCLUSION: Students have more clinical access to the major modalities of US, CT and MRI, and this appears to be a major factor into why student wish to specialise in these modalities. Role extension and higher wages were given as possible incentives that would make specialising in Mammography more appealing. The gender divide may have to be bridged to enable crucial recruitment as male students feel discriminated against. PMID- 30292492 TI - Behavioral Deficits at 18-22 Months of Age Are Associated with Early Cerebellar Injury and Cognitive and Language Performance in Children Born Extremely Preterm. AB - OBJECTIVE: To investigate associations in toddlers born extremely preterm (<28 weeks) between neonatal neuroimaging and 18- to 22-month developmental and behavioral outcomes. STUDY DESIGN: Cohort analysis from the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network Surfactant Positive Airway Pressure and Pulse Oximetry Trial Neuroimaging and Neurodevelopmental Outcomes Study of infants born extremely preterm. Subjects underwent cranial ultrasonography and near-term magnetic resonance imaging (MRI). At 18-22 months of corrected age, the assessment included the Brief Infant Toddler Social Emotional Assessment (BITSEA) Problem and Competence Scale scores and the Bayley Scales of Infant Development, Third Edition (Bayley-III). The BITSEA Problem Scale assesses dysregulation; the Competence Scale assesses social-emotional competence. We examined associations of Problem and Competence scores and positive screen rates with cranial ultrasonography and near-term MRI. Mean BITSEA and Bayley-III scores were compared using ANOVA and positive screen rates with the chi2 test. We computed correlations between BITSEA and Bayley-III scores. RESULTS: Of the 397 children, positive BITSEA screens were found in 34% for the Problem score and 26% for the Competence score. Presence of lesions on near-term MRI that included cerebellar lesions were significantly associated with lower BITSEA Competence but not with Problem scores; Competence scores were inversely related to the presence/significance of lesions. Positive screens on Competence scores and on both Competence and Problem scores were significantly associated with Bayley-III cognitive and language scores <85 (P < .001). CONCLUSIONS: Social-emotional competence contributes to deficits in cognitive and language development. Presence of injury on near-term MRI that includes cerebellar lesions is associated with later social-emotional competence and may be a useful predictor to guide early assessment and intervention. TRIAL REGISTRATION: ClinicalTrials.gov: NCT00063063 and NCT00233324. PMID- 30292507 TI - Radiographer reporting of neurological magnetic resonance imaging examinations of the head and cervical spine: Findings of an accredited postgraduate programme. AB - INTRODUCTION: To analyse the objective structured examination (OSE) results of the first cohorts of radiographers (n = 13) who successfully completed an accredited postgraduate programme in clinical reporting of neurological magnetic resonance imaging (MRI) examinations of the head and cervical spine. METHODS: Forty MRI examinations were used in the OSE which included a range of abnormal cases (prevalence of abnormal examinations approximated 50%) and included: haemorrhage, infarction, demyelination disease, abscess, mass lesions (metastatic deposits, meningioma, glioma, astrocytoma); and disc disease, cord compression, stenosis, ligament rupture, syringomyelia appearances on patients referred from a range of referral sources. Normal variants and incidental findings were also included. True/false positive and negative fractions were used to mark the responses which were also scored for agreement with the previously agreed expected answers based on agreement between three consultant radiologists' reports. RESULTS: The mean sensitivity, specificity and agreement rates for all head and cervical spine investigations (n = 520) combined were 98.86%, 98.08% and 88.37%, respectively. The highest scoring cases were cases which included astrocytoma, disc protrusion with cord compression and glioma. The most common errors were related to syringomyelia, ligament rupture and vertebral fracture. CONCLUSIONS: These OSE results suggest that in an academic setting, and following an accredited postgraduate education programme, this group of radiographers has the ability to correctly identify normal MRI examinations of the head/cervical spine and are able to provide a report on the abnormal appearances to a high standard. Further work is required to confirm the clinical application of these findings.

AB - INTRODUCTION: The aim of the study was to evaluate the performance of radiographers in image interpretation of magnetic resonance imaging (MRI) brain, spine and knee examinations following a nine-month work based postgraduate MRI module. METHODS: Twenty-seven participants each submitted 60 image commentaries taken from prospective clinical workloads. The image interpretations (n = 1620) comprised brain, spine, and knee MRI examinations. Prevalence of abnormal examinations approximated 53% (brain), 74% (spine), and 73% (knee), and included acute and chronic pathology, normal variants and incidental findings. Each image interpretation was graded against reference standard consultant radiologist definitive report. RESULTS: The radiographer's performance on brain image interpretations demonstrated mean accuracy at 86.7% (95% CI 83.4-89.3) with sensitivity and specificity of 84% (95% CI 80.9-86.4) and 89.7% (95% CI 86.2 92.6) respectively. For spinal interpretations the mean accuracy was 86.4% (95% CI 83.4-89.0), sensitivity was 90.2% (95% CI 88.2-92), mean specificity was 75.3% (95% CI 69.4-80.4). The mean results for knee interpretation accuracy were 80.9% (95% CI 77.3-84.1), sensitivity was 83.3% (95% CI 80.8-85.5), with 74.3% specificity (95% CI 67.4-80.4). CONCLUSIONS: The radiographer's demonstrated skills in brain, spine and knee MRI examination image interpretation. These skills are not to replace radiologist reporting but to meet regulating body standards of proficiency, and to assist decision making in communicating unexpected serious findings, and/or extend scan range and sequences. Further research is required to investigate the impact of these skills on adjusting scan protocols or flagging urgent findings in clinical practice. PMID- 30292509 TI - Development and evaluation of a deep knowledge and skills based assignment: Using MRI safety as an example. AB - INTRODUCTION: Using magnetic resonance imaging (MRI) safety as an example, this paper discusses the development of an innovative multiple-step assignment task designed to increase student engagement and learning of important concepts. The paper also summarises student feedback about the assessment as well as thematic analysis of categories thought important to students. METHOD: A multi-step assignment was designed. Step one was the reading of a MRI safety article, step two was the construction and submission of 5 short answer questions believed to be important concepts of understanding and step three was the answering of 15 questions compiled from all student questions by the course coordinator. The motivation to answer the course coordinator compiled questions was the knowledge that five of these questions would be in the end of course examination. At the completion of the assignment, students were asked to complete an anonymous on line questionnaire about the assignment task. Thematic analysis was used to gather data on what students perceived to be the most and least important concepts in the article. RESULTS: All students replying to the survey stated that they understood why MRI safety is an important topic and 79% reported this assignment was both a positive learning experience and provided understanding of the topic. Only 18% of students believed that they would have learned more through a formal lecture. CONCLUSION: The design of this assignment task can be used in any course, not just in medical radiation science, where student learning and understanding is critical. PMID- 30292510 TI - Variation in the length and structure of reports written by reporting radiographers: A retrospective study. AB - INTRODUCTION: The literature suggests that there is variation in various features of the written radiology report for a range of body areas and imaging modalities. The retrospective study presented here aims to determine if similar variation is demonstrated in a group of 5 reporting radiographers in a UK NHS Trust. METHODS: Full reports for 1530 knee radiographic examinations performed from accident and emergency referrals were extracted for a 12-month period from a Radiology Information System (RIS) into Excel. Copied into Word, the word count function was used for each report and the number of words and characters (without spaces) was returned into Excel. Average word count and word length per report, by radiographer, were calculated for the following sections of the report: report title, main body and signature. SPSS was used to perform inferential statistical analysis. RESULTS: A wide range in the maximum and minimum average report lengths (60.88 v 17.83 words) was demonstrated. Statistically significant differences (p < 0.05) were seen between all but one pair-wise comparison (Rad 2 v Rad 4; p = 0.98) for the overall report length; for the length of the findings section, four pair-wise comparisons did not reach significance. Average word length demonstrated less variation. 4 out of 5 radiographers always included a report title; 3 out of 5 never included a report signature. There was a strong negative correlation between experience and report length. CONCLUSION: Variation in report structure and length, as well as word length, was seen, comparable to studies of radiologist reports. Further research is required to investigate the drivers of this variation, and determine if there is any clinical significance.

AB - OBJECTIVES: To evaluate the current evidence for whether Fracture Liaison Services are being utilised effectively in the UK to aid in the prevention of fragility fractures. KEY FINDINGS: Radiological under-reporting and non standardised assessment of fragility fractures still persist, with low numbers of patients undergoing a risk assessment and treatment for secondary prevention of fracture. In order to improve care for these patients, the reporting of vertebral fractures must be improved and standardised in order to identify patients at increased risk of secondary fragility fractures. Fracture Liaison Services determine the need for anti-resorptive therapy for the prevention of future fragility fractures. Targeted treatment of at-risk patient groups has been shown to reduce the risk of further fracture. CONCLUSION: Fracture Liaison Services have been shown to be cost effective, while reducing the risk of secondary fractures, but they are not currently offered by all NHS providers. PMID- 30292512 TI - The experiences of women receiving brachytherapy for cervical cancer: A systematic literature review. AB - OBJECTIVES: To determine women's experiences of brachytherapy for cervical cancer. KEY FINDINGS: Nineteen studies were included for data extraction/synthesis. Twelve studies focussed on psychological issues, seven on pharmacological aspects of women's experiences. Themes of anxiety, distress, pain, informational needs and non-pharmacological interventions were found. Nine out of ten psychological studies described brachytherapy as a distressing experience causing anxiety and distress for most women. Non-pharmacological interventions were found to be effective and inexpensive adjuncts. Peri and post operative pharmacological management was variable, but duration of procedure was an important factor. CONCLUSION: Brachytherapy for gynaecological cancer causes varying levels of pain, anxiety and distress. To improve women's experiences there needs to be better pain management, patient information and the development of non-pharmacological interventions. Future recommendations are to develop clinical support guidelines, audit the quality of services and develop effective interventions to improve women's experiences of brachytherapy for locally advanced cervical cancer.

AB - INTRODUCTION: The aim of this article is to give an insight into radiography as a science and a discipline from the viewpoints of knowledge interest and methodological approach and design. METHODS: Original articles published in Radiography (n = 184) and the Journal of Clinical Radiography and Radiotherapy (n = 10) at the timeline 2015 to 3/2017 were reviewed for research focus and the methodology used. To abstract the results, thematisation analysis was used. RESULTS: Out of 194 studies analysed, 99 (50%) were found to have a technical, 80 (42%) a practical and 15 (8%) a critical interest of knowledge. The research methodologies used did not rigorously fit into the methodological approach expected on the basis of the interest of knowledge. CONCLUSION: Radiography as a science seems to have mostly a technical and practical interest of knowledge, but somewhat critical research is also being made. It seems to be a remarkably open and flexible science when it comes to the use of research methodologies. More discussion and research on the science name and paradigm is needed in order to strengthen the scientific status of radiography. PMID- 30292515 TI - Diagnostic accuracy of Magnetic Resonance Imaging using liver tissue specific contrast agents and contrast enhanced Multi Detector Computed Tomography: A systematic review of diagnostic test in Hepatocellular Carcinoma (HCC). AB - OBJECTIVES: The aim of this systematic review is to investigate diagnostic accuracy of Magnetic Resonance Imaging (MRI) scans using liver specific tissue contrast media over contrast enhanced Multi Detector CT (MDCT) in diagnoses of Hepatocellular Carcinoma (HCC) in patients with chronic liver disease. KEY FINDINGS: A total of 8 diagnostic studies were identified and generally considered of high quality. The studies reported sufficient evidence on sensitivity and specificity, which was synthesised and summarised providing an overview of the evidence. Findings indicate that MRI scans using liver specific tissue contrast have a better diagnostic performance compared to contrast enhanced MDCT in diagnostic work-up of HCC in patients with chronic liver disease. CONCLUSION: The current review identified sufficient high quality studies reporting statistical difference (P < 0.05), to establish the superiority of gadoxetetic acid enhanced MRI for sensitivity and specificity in comparison to MDCT in the diagnosis of HCC in chronic liver disease.

PMID- 30292517 TI - Muscle thickness and echo-intensity changes of the quadriceps femoris muscle during a strength training program. AB - INTRODUCTION: Ultrasound (US) has an important role in musculoskeletal (MSK) evaluation, allowing the study of muscle morphology and function. Muscle thickness (MT) and muscle echo-intensity (EI) are two important parameters that may quantify muscle structural adaptations to a variety of stimuli. The aim was to explore the potential of quantitative US imaging for assessing the adaptations and responses of the muscle tissue to increased contractile activity using B-mode US. This study was centred on the quadriceps femoris muscle contractile activity on MT and EI. METHODS AND MATERIALS: Twenty-eight young male adults participated in the study, divided in a control group and two training groups performing concentric or eccentric strength training, respectively. The effect of a 15-week strength program was studied on MT and EI in several regions of the heads of the quadriceps femoris using B-mode US. All images acquisitions and measurements were done by the same experience sonographer. RESULTS: Strength training resulted in an increase of MT at all muscles and sites (p < 0.05), except the VM. Strength training failed in changing EI in most of the quadriceps femoris, except in the VI and some regions of the VL. No statistically significant differences were observed in our quantitative US parameters between concentric and eccentric training (p > 0.05). CONCLUSION: These results emphasise the value of MT as a quantifiable muscle US method for evaluating muscle adaptation to exercise training. However, the inconsistency of the EI values indicates that more studies are needed to develop it as an accurate diagnostic tool. PMID- 30292519 TI - A comparative study about motivations, expectations and future plans for professional development in four European radiography programs. AB - INTRODUCTION: This study aims to compare motivations, expectations and work plans of students and teaching-staff from four different European radiography programs, it aims also to explore areas that could be included to advance post graduate studies. METHODS: Two different questionnaires (open- and closed-end questions) were applied to key-informants, students who had just completed their bachelor thesis and teaching-staff, to collect data regarding motivations, expectations, challenges and potentials for radiography education and, plans for further work. Descriptive statistics and thematic analysis were performed according to the nature of the questions. RESULTS: The response rates were 45% (students) and 68% (teaching-staff). The motivations to study radiography were similar between students: to work in a healthcare-service, helping people, manipulating high-end technologies, providing service while combining different knowledge (physics, patient-care, physiology, anatomy). 75% of the students did not reach all their expectations due to the lack of focused and updated content for some areas. The teaching-staff were expecting an extension of the radiographers' role. The development of advance studies in computed tomography and magnetic resonance was highlighted as important by students. Future work plans included: self improvement, continuation of studies, specialization, research and collaborations. CONCLUSIONS: This study increased the understanding of radiography education and provides insights into future perspectives. Participants have similar motivations, expectations and future plans. Improvements in education should focus on technological developments and meeting job market demands. Further studies should be performed to identify approaches that acknowledge the specific needs of each country, while also providing strategies to harmonize radiography education in Europe. PMID- 30292518 TI - Assessment of left ventricular ejection fraction with late-systolic and mid diastolic cardiac phases using multi-slice computed tomography. AB - INTRODUCTION: Multi-slice computed tomography (MSCT) is an accurate tool for the assessment of left ventricular ejection fraction (LVEF). However, in order to reduce radiation dose, prospective acquisition protocols are currently used, in which the end-systole and end-diastole are not scanned. Our aim was to study the accuracy of the assessment of LVEF using fixed late-systolic and mid-diastolic cardiac phases compared with echocardiography. METHODS: MSCT-derived LVEF was measured with off-line commercially available software packages, and compared with echocardiography-derived LVEF using the Simpson's method. LVEF was categorized as normal vs. abnormal (50% cut-off) and was also analyzed as a quantitative parameter. Bland-Altman plots and Pearson correlations were used for inter-technique comparisons. RESULTS: 58 patients were included. The sensitivity and specificity of fixed-phase MSCT when compared with echocardiography for detection of LVEF <=50% was 79% (95% CI = 65-89%) and 43% (10-82%). Misclassification was associated with older age (68 +/- 12 vs. 54 +/- 13 years, p < 0.01), faster heart rate (79 +/- 14 vs. 68 +/- 10 bpm, p = 0.01), and LV hypertrophy (86% vs. 52%, p = 0.03). The quantitative comparison revealed no correlation (r = 0.095, p = 0.478) and a significantly different LVEF (median[IQR], 57.0[50.5-63.1]% vs. 61.0[57.3-64.3]%, p = 0.03). The observed bias between the two methods was -3.7% with broad limits of agreement (+/-25.5%). CONCLUSIONS: Fixed-phase MSCT assessment using late-systole and mid-diastole agreed in defining normal and abnormal LVEF in 76% of patients when compared with echocardiography. Quantitation of LVEF by this method yielded significantly lower values of LVEF and showed no correlation. Thus, accurate quantitation of LVEF by MSCT requires the acquisition of end-systolic and end-diastolic phases.

AB - INTRODUCTION: Internationally it is recommended that quality assurance (QA) testing of MR systems is the responsibility of MR professionals to ensure efficient scanner performance. This study aims to explore the opinions and attitudes of MR professionals in the Kingdom of Saudi Arabia (KSA) regarding the current status of routine QA testing within MRI departments. METHODS: A qualitative approach was adopted, with MR professionals working in public, semi public and private hospitals in the KSA invited to participate in this interview based study. A total of 52 individual semi-structured interviews were conducted with purposive sampling of MR radiographers and medical physicists based at 19 major centres across the three main geographical regions in the KSA. Data went through duration of coding following qualitative data analysis framework based on Miles and Huberman's philosophical underpinnings. RESULTS: The findings demonstrated that 89.5% (n = 17) of the MRI departments surveyed rely on the service provided by the equipment vendor in order to ensure ongoing MR scanner performance. Overall, the level of MR radiographer participation in weekly MR scanner QA testing was low (13.3%, n = 3). Lack of legal requirement, professional organisation and knowledge were highlighted as the principal factors limiting radiographer involvement in the weekly MR QA in the KSA. CONCLUSION: The results of this study support the establishment of a legal requirement and national policy in order to encourage radiographers in the KSA to take an active role in MRI QA testing to enable suboptimal MR scanner performance to be identified before it becomes clinically evident. PMID- 30292521 TI - Advances in offline approaches for chemically speciated measurements of trace gas phase organic compounds via adsorbent tubes in an integrated sampling-to-analysis system. AB - Gas-phase organic compounds across a range of volatilities, including volatile organic compounds (VOCs), are key components of outdoor air, indoor spaces, and a variety of other anthropogenic and biogenic systems. The collection of offline samples on adsorbent-packed tubes for analysis on laboratory instrumentation has been in use for decades, but with limited sensitivities and compound coverage. We present and evaluate our integrated sampling-to-analysis system that enables offline detailed chemical characterization of multi-faceted organic mixtures at trace concentrations. Its capabilities extend across a diverse variety of VOCs with different molecular features, as well as intermediate and semivolatile organic compounds (I/SVOCs). Samples can be collected manually or via automated devices that have been applied in chamber, field, and aircraft platforms. The laboratory instrumentation can be coupled to both a high resolution mass spectrometer (MS) and a traditional quadrupole MS, though performance metrics presented in this study are determined via the traditional MS. We demonstrate capabilities for detailed chemical characterization and routine performance for a wide range of compound functionalities at sub-part per trillion (ppt) concentrations, and as low as <100 parts per quadrillion (ppq), yielding 3300 observed unique compound peaks in a single indoor air sample. These limits of detection and compound coverage were accomplished through a holistic optimization of the entire system and lifecycle of adsorbent tubes. We present our best practices for all aspects of tube production, handling, sampling, and analysis, and an examination of commercially-available materials and our custom adsorbent tubes using a diverse mix of VOC, IVOC, and SVOC standards, including difficult to measure analytes across a range of polarities and functionalities. In many aspects, the commercially-available materials and tube conditioners tested were insufficient for achieving low-ppt measurements. PMID- 30292522 TI - A fully automated approach for the analysis of 37 psychoactive substances in raw wastewater based on on-line solid phase extraction-liquid chromatography-tandem mass spectrometry. AB - This work presents a multi-residue method for the simultaneous determination of 37 legal and illicit psychoactive substances in wastewater, including the most common illicit drugs (cocaine-related compounds, amphetamine-type stimulants, hallucinogens, opiates/opioids, and cannabinoids), new psychoactive substances (two synthetic cathinones, the synthetic opioid AH-7921, and the arylcyclohexylamine methoxetamine), and legal but controlled psychoactive substances (stimulants, benzodiazepines, antidepressants, sedatives, antipsychotics, and hypnotics). To this end a fully automated analytical approach based on solid phase extraction coupled in series to liquid chromatography tandem mass spectrometry detection (on-line SPE- LC-MS/MS) was used. The methodology developed was validated in terms of linearity, recovery, repeatability, and sensitivity in wastewater. Method linearity was between 0.1 ng/L (or the analyte limit of quantification if higher) and 2,000 ng/L (10,250 ng/L in the case of caffeine). Absolute recoveries were variable (between 5% and 132%), depending on the analyte. However, the use of isotopically labeled compounds corrected for analyte losses during the extraction process and matrix effects (relative recoveries within the range of 80-120%). Repeatability of the method was satisfactory for all analytes, with RSD values lower than 13% for most compounds. Limits of detection and quantification in wastewater were below 7 and 23 ng/L, respectively, for all analytes except lormetazepam (10 and 32 ng/L), caffeine (13 and 44 ng/L), and the cannabinoids 11-nor-9-carboxy- Delta9-tetrahydrocannabinol (18 and 61 ng/L) and 11-hydroxy-Delta9- tetrahydrocannabinol (69 and 228 ng/L). The method was applied to the analysis of wastewater samples collected daily in Barcelona for one week. Twenty-five of the 37 analytes were detected in the samples analyzed. Average concentrations ranged from 7 ng/L in the case of zolpidem to 54 MUg/L in the case of caffeine. PMID- 30292523 TI - Cellular and synaptic reorganization of arcuate NPY/AgRP and POMC neurons after exercise. AB - OBJECTIVE: Hypothalamic Pro-opiomelanocortin (POMC) and Neuropeptide Y/Agouti Related Peptide (NPY/AgRP) neurons are critical nodes of a circuit within the brain that sense key metabolic cues as well as regulate metabolism. Importantly, these neurons retain an innate ability to rapidly reorganize synaptic inputs and electrophysiological properties in response to metabolic state. While the cellular properties of these neurons have been investigated in the context of obesity, much less is known about the effects of exercise training. METHODS: In order to further investigate this issue, we utilized neuron-specific transgenic mouse models to identify POMC and NPY/AgRP neurons for patch-clamp electrophysiology experiments. RESULTS: Using whole-cell patch-clamp electrophysiology, we found exercise depolarized and increased firing rate of arcuate POMC neurons. The increased excitability of POMC neurons was concomitant with increased excitatory inputs to these neurons. In agreement with recent work suggesting leptin plays an important role in the synaptic (re)organization of POMC neurons, POMC neurons which express leptin receptors were more sensitive to exercise-induced changes in biophysical properties. Opposite to effects observed in POMC neurons, NPY neurons were shunted toward inhibition following exercise. CONCLUSIONS: Together, these data support a rapid reorganization of synaptic inputs and biophysical properties in response to exercise, which may facilitate adaptations to altered energy balance and glucose metabolism.

AB - Post-tonsillectomy hemorrhage is a frequent occurrence in the emergency department, and management of potentially life-threatening and ongoing bleeding by the emergency physician is challenging. Limited evidence-based guidelines exist, and practice patterns vary widely. We administered nebulized tranexamic acid to achieve hemostasis in a pediatric patient with associated bleeding cessation prior to definitive operative management. PMID- 30292525 TI - Native english speakers and English as a Foreign Language (EFL) students' performance and notetaking in a Doctor of pharmacy health systems course. AB - BACKGROUND: Academic pharmacy programs continue to diversify in student population. While the challenges of non-native language speakers have been opined, there is scant research on their performance in comparison with native language speakers nor is there much information on differences in the processes used in academic preparation, such as on note-taking. OBJECTIVE: The objectives of this study were to: (1) identify differences in test performance between native English speakers and students for whom English is a foreign language (EFL) in a health systems PharmD course, and (2) examine differences between these two groups in note-taking attitudes and behaviors. METHODS: Students' self-reported data as native English-speaking or EFL were acquired from the University Office of Admissions. Students' performance was measured on examinations covering lecture content, with independent-sample t tests discerning differences on all 3 examinations. T-tests were also used to ascertain differences on examination scores by student race/ethnicity and on differences in their response to a survey on attitudes, behaviors, and satisfaction with note-taking. RESULTS: EFL students scored significantly lower on the latter two examinations and on the average of the three examinations by over 7%. EFL students reported lower satisfaction with the accuracy and completeness of their notes and indicated that peers were less likely to borrow their notes. They also reported being more likely to be distracted in class by peers' laptop note-taking, even though there were many similarities between the two groups in how they approached note-taking. CONCLUSIONS: EFL student performance was lower than that of native English speakers on examinations. EFL students were less satisfied with the quality of their notes. Further research is needed to identify effective strategies for improving the learning experience of EFL students. Academic administration can identify mechanisms to facilitate a learning environment conducive for their success. PMID- 30292526 TI - Management of bleeding in major burn surgery. AB - Major burn surgery is often associated with excessive bleeding and massive transfusion, and the development of a coagulopathy during major burn surgery is associated with increased morbidity and mortality. The aim of this study was to review the literature on intraoperative haemostatic resuscitation of burn patients during necrectomy to reveal strategies applied for haemostatic monitoring and resuscitation. We searched PubMed, EMBASE, and CENTRAL for studies published in the period 2006-2017 concerning bleeding issues related to burn surgery i.e. coagulopathy, transfusion requirements and clinical outcomes. In a broad search, a total of 1375 papers were identified. 124 of these fulfilled the inclusion criteria, and six of these were included for review. The literature confirmed that transfusion requirements increases with burn injury severity and that haemostatic monitoring by TEG(r) (thrombelastography) or ROTEM(r) (rotational thromboelastometry) significantly decreased intraoperative transfusions and was useful in predicting and goal-directing haemostatic therapy during excision surgery. Resuscitation of bleeding during major burn surgery in many instances was neither standardized nor haemostatic. We suggest that resuscitation should aim for normal haemostasis during the bleeding phase through close haemostatic monitoring and resuscitation. Randomised controlled trials are highly warranted to confirm the benefit of this concept. PMID- 30292527 TI - Correction to Lancet Oncol 2018; 19: 1289-306. PMID- 30292528 TI - Effect of nurse staffing on rehospitalizations and emergency department visits among short-stay nursing home residents: A Cross-sectional study using the US Nursing Home Compare database. AB - The aim of this study was to examine the effect of nurse staffing on both rehospitalizations and emergency department emergency department visits among short-stay nursing home residents in the United States. Data for 11,132 US nursing homes were drawn from the 2016 Nursing Home Compare. We found that the Five-Star Quality Rating System's staffing rating is a significant predictor for the rates of rehospitalization and emergency department visit among short-stay nursing home residents. The results also showed the importance of registered nurse staffing in nursing home caring for short-stay residents. Administrators and policy-makers can employ the findings to formulate management strategies that will reduce rehospitalizations and emergency department visits among nursing home residents. PMID- 30292529 TI - The influence of the middle hepatic vein and its impact on outcomes in right lobe living donor liver transplantation. AB - BACKGROUND: In adult right lobe living donor liver transplantation, the decision to include the middle hepatic vein (MHV) remains controversial. METHODS: A retrospective analysis of 50 R-LDLTs between January 2008 and June 2016 was performed. RESULTS: Twenty-one procedures were performed using a MHV+ graft (42.0%) and 29 procedures using a MHV- graft (58%). MHV- donors were taller (173 vs 166 cm, p = 0.004) with a larger standard liver volume (1351 vs 1245 mls, p = 0.014) compared to MHV+ donors. The duration of operation for donors was significantly longer in the MHV+ group (530 (313-975) mins) compared to the MHV- group (489 (336-708) mins) (p = 0.029). Similarly, the operative time for recipients was longer in the MHV+ group (660 (428-831) mins) compared to MHV- (579 (359-1214) mins) (p = 0.023). MHV- grafts were heavier compared to MHV+ grafts (918 vs 711 g, p = 0.017). Recipient mortality rates and Kaplan-Meier survival analysis were comparable (p = 0.411). All donors were well at last review. CONCLUSION: Both MHV+ and MHV- grafts are safe for the donor and recipient. The decision to take the MHV should be based on specific donor recipient characteristics. PMID- 30292530 TI - Novel method of fitting of children with auditory brainstem implants. AB - OBJECTIVES: To develop a reliable and objective fitting method for use with young children with an auditory brainstem implant (ABI). MATERIALS AND METHODS: Subjects were 17 young children implanted with an ABI with the mean age 2 years and 4 months (8-64 months). Evoked auditory brainstem response (eABR) measurements were performed intraoperatively and at activation in order to record the auditory response and non-auditory side effects. Each child was tested to observe any subjective responses to the electric stimuli and non-auditory side effects. All children were fitted based on the postoperative eABR. The minimum follow up time was 12 months. RESULTS: Intraoperatively an eABR could be obtained in all children. The responses were recordable from 75-100% of all electrodes. At initial stimulation eABR were recordable in all children. The eABR was obtained in 79.7% of all electrodes (25-100%) with a mean eABR threshold of 22.3 nC. eABR without any non-auditory stimulation was recorded on all electrodes in 11 children. Mixed eABR and non-auditory responses were recorded on 2-6 electrodes in 6 children. The subjective auditory responses for at least 1 electrode were noted in 15 children. In the 2 remaining cases the auditory response was obtained only when the device was activated. In all children the subjective responses were within the estimated dynamic range for each electrode. Each child was able to accept up to 100% of volume of the created map. The non-auditory response was observed only on children and electrodes with mixed eABR and non-auditory responses. The mean CAP score at 6 months after the activation was 2.4 (1-4). CONCLUSIONS: eABR seems to be a reliable tool to judge ABI electrode placement and a reliable method for fitting of young children with an ABI. The data suggest that eABR-based fitting helps children to more quickly achieve auditory perception and development.

PMID- 30292532 TI - A mathematical model of the biochemical network underlying left-right asymmetry establishment in mammals. AB - The expression of the TGF-beta protein Nodal on the left side of vertebrate embryos is a determining event in the development of internal-organ asymmetry. We present a mathematical model for the control of the expression of Nodal and its antagonist Lefty consisting entirely of realistic elementary reactions. We analyze the model in the absence of Lefty and find a wide range of parameters over which bistability (two stable steady states) is observed, with one stable steady state a low-Nodal state corresponding to the right-hand developmental fate, and the other a high-Nodal state corresponding to the left. We find that bistability requires a transcription factor containing two molecules of phosphorylated Smad2. A numerical survey of the full model, including Lefty, shows the effects of Lefty on the potential for bistability, and on the conditions that lead to the system reaching one or the other steady state. PMID- 30292533 TI - Increasing complexity: Mechanical guidance and feedback loops as a basis for self organization in morphogenesis. AB - The article is devoted to physical views on embryo development as a combination of structurally stable dynamics and symmetry-breaking events in the general process of self-organization. The first corresponds to the deterministic aspect of embryo development. The second type of processes is associated with sudden increase of variability in the periods of symmetry-breaking, which manifests unstable dynamics. The biological basis under these considerations includes chemokinetics (a system of inductors, repressors, and interaction with their next surrounding) and morphomechanics (i.e. mechanotransduction, mechanosensing, and related feedback loops). Although the latter research area is evolving rapidly, up to this time the role of mechanical properties of embryonic tissues and mechano-dependent processes in them are integrated in the general picture of embryo development to a lesser extent than biochemical signaling. For this reason, the present article is mostly devoted to experimental data on morphomechanics in the process of embryo development, also including analysis of its limitations and possible contradictions. The general system of feedback-loops and system dynamics delineated in this review is in large part a repetition of the views of Lev Beloussov, who was one of the founders of the whole areas of morphomechanics and morphodynamics, and to whose memory this article is dedicated.

AB - Quantifying ventricular deformation in health and disease is critical to our understanding of normal heart function, heart disease mechanisms, and the effect of medical treatments. Imaging modalities have been developed that can measure ventricular deformation non-invasively. However, because of the small thickness, complex shape, and anatomic position of the right ventricle, using these technologies to determine its deformation remains challenging. Here we develop a first fiduciary marker-based method to assess heterogeneity and anisotropy of right ventricular epicardial strain across the entire free wall. To this end, we combine a high-density array of sonomicrometry crystals implanted across the entire right ventricular epicardial surface with a subdivision surface algorithm and a large deformation kinematics framework. We demonstrate our approach on four beating ovine hearts and present a preliminary regional analysis of circumferential, longitudinal, and areal strain. Moreover, we illustrate maps of the same strains across the entire right ventricular epicardial surface to highlight their spatial heterogeneity and anisotropy. We observe in these animals that RV epicardial strains vary throughout the cardiac cycle, are heterogeneous across the RV free wall, and are anisotropic with larger compressive strains, i.e., contraction, in the longitudinal direction than in the circumferential direction. Average peak compressive strains vary by region between -3.34% and 8.29% in circumferential direction, and -4.02% and -10.57% in longitudinal direction. In summary, we introduce an experimental framework that will allow us to study disease- and device-induced deformations, and long-term consequences of these deformations, including heterogeneous and anisotropic effects.

AB - The mechanisms underlying behavioral synchrony during psychological counseling are not clear. Recent research has provided evidence that pervasive synchrony is associated with interpersonal brain synchronization (IBS) and possibly contributes to the positive working alliance-the degree to which the counseling dyads engage in collaborative and purposive work. Our study explored the IBS between the clients and the counselors using functional near-infrared spectroscopy (fNIRS)-based hyperscanning. Thirty-four participants (as clients) were randomly assigned either to the psychological counseling group or to the chatting group; three female professional counselors provided them with 40 minutes of psychological counseling or chatting. We found better working alliances and increased IBS in the right temporo-parietal junction (rTPJ) between clients and counselors during psychological counseling (versus chatting). Such IBS also correlated with the bond of working alliance. To our knowledge, our work represents the first demonstration of fNIRS-hyperscanning measurements for synchronous brain activity between the clients and counselors. This study refines the neural explanation of behavioral synchrony during psychological counseling. PMID- 30292536 TI - Polymorphism of Foxp3 gene affects the frequency of regulatory T cells and disease activity in patients with rheumatoid arthritis in Iranian population. AB - Rheumatoid arthritis (RA) is a chronic autoimmune disease that mainly affects joints and characterized by chronic joint inflammation and infiltration of various immune cells in the synovium. Forkhead box P3 (Foxp3)-expressing regulatory T cells (Tregs) play a crucial role in preventing autoimmunity and undesirable T cell responses. However, there are controversial reports regarding the defective function or frequency of these cells in various studies, which may be in part related to different polymorphisms of FoxP3 and influence of ethnicity on these differences. Therefore, the main subject of this study was to evaluate the association of Foxp3 gene polymorphism and Treg frequency in Iranian patients with RA. Accordingly, 240 RA patients diagnosed according to American college of rheumatology 2010 criteria and 240 normal subjects were recruited for this study. Genomic DNA was genotyped for -3279 C/A Foxp3 gene SNP using the PCR-RFLP. The frequency of Tregs and serum levels of interleukin (IL)-10, transforming growth factor (TGF)-beta, anti-cyclic citrullinated peptide (CCP) and rheumatoid factor (RF) were determined by flow cytometry and ELISA methods, respectively. The results showed a significant association of Foxp3 -3279 A allele with augmented risk of RA in Iranian patients compared to wild-type allele. While the frequencies of CA and AA genotypes were significantly higher in patients, RA patients with AA genotype had a significant lower frequency of Tregs compared to patients with CC and CA genotypes. Consistently, TGF-beta and IL-10 significantly diminished in patients with AA genotype compared to patients with CA and CC genotypes. Our findings indicated that the AA genotype of Foxp3 in RA patients is associated with downregulation of Tregs and susceptibility to RA in the Iranian population. PMID- 30292537 TI - Predicting hospital associated disability from imbalanced data using supervised learning. AB - Hospitalization of elderly patients can lead to serious adverse effects on their functional capability. Identifying the underlying factors leading to such adverse effects is an active area of medical research. The purpose of the current paper is to show the potential of artificial intelligence in the form of machine learning to complement the existing medical research. This is accomplished by studying the outcome of hospitalization of elderly patients as a supervised learning task. A rich set of features characterizing the medical and social situation of elderly patients is leveraged and using confusion matrices, association rule mining, and two different classes of supervised learning algorithms, it is shown that the need for help and supervision are the most important features predicting whether these patients will return home after hospitalization. Such findings can help to improve hospitalization and rehabilitation of elderly patients. PMID- 30292538 TI - Towards a modular decision support system for radiomics: A case study on rectal cancer. AB - Following the personalized medicine paradigm, there is a growing interest in medical agents capable of predicting the effect of therapies on patients, by exploiting the amount of data that is now available for each patient. In disciplines like oncology, where images and scans are available, the exploitation of medical images can provide an additional source of potentially useful information. The study and analysis of features extracted by medical images, exploited for predictive purposes, is termed radiomics. A number of tools are available for supporting some of the steps of the radiomics process, but there is a lack of approaches which are able to deal with all the steps of the process. In this paper, we introduce a medical agent-based decision support system capable of handling the whole radiomics process. The proposed system is tested on two independent data sets of patients treated for rectal cancer. Experimental results indicate that the system is able to generate highly performant centre-specific predictive model, and show the issues related to differences in data sets collected by different centres, and how such issues can affect the performance of the generated predictive models. PMID- 30292539 TI - The Birth of the 3D Genome during Early Embryonic Development. AB - The 3D structure of chromatin in the nucleus is important for the regulation of gene expression and the correct deployment of developmental programs. The differentiation of germ cells and early embryonic development (when the zygotic genome is activated and transcription is taking place for the first time) are accompanied by dramatic changes in gene expression and the epigenetic landscape. Recent studies used Hi-C to investigate the 3D chromatin organization during these developmental transitions, uncovering remarkable remodeling of the 3D genome. Here, we highlight the changes described so far and discuss some of the implications that these findings have for our understanding of the mechanisms and functionality of 3D chromatin architecture.

PMID- 30292541 TI - Effect of Ciliary Neurotrophic Factor on Retinal Neurodegeneration in Patients with Macular Telangiectasia Type 2: A Randomized Clinical Trial. AB - PURPOSE: To test the effects of an encapsulated cell-based delivery of a neuroprotective agent, ciliary neurotrophic factor (CNTF), on progression of macular telangiectasia type 2, a neurodegenerative disease with no proven effective therapy. DESIGN: Randomized sham-controlled clinical trial. PARTICIPANTS: Ninety-nine study eyes of 67 eligible participants were enrolled. METHODS: Single-masked randomized clinical trial of 24 months' duration conducted from May 2014 through April 2017 in 11 clinical centers of retinal specialists in the United States and Australia. Participants were randomized 1:1 to surgical implantation of intravitreal sustained delivery of human CNTF versus a sham procedure. MAIN OUTCOME MEASURES: The primary outcome was the difference in the area of neurodegeneration as measured in the area of the ellipsoid zone disruption (or photoreceptor loss) measured on spectral-domain (SD) OCT images at 24 months from baseline between the treated and untreated groups. Secondary outcomes included comparison of visual function changes between treatment groups. RESULTS: Among the 67 participants who were randomized (mean age, 62+/-8.9 years; 41 women [61%]; 58 white persons [86%]), 65 (97%) completed the study. Two participants (3 study eyes) died and 3 participants (4 eyes) were found ineligible. The eyes receiving sham treatment had 31% greater progression of neurodegeneration than the CNTF-treated eyes. The difference in mean area of photoreceptor loss was 0.05+/-0.03 mm2 (P = 0.04) at 24 months. Retinal sensitivity changes, measured using microperimetry, were correlated highly with the changes in the area of photoreceptor loss (r = 0.86; P < 0.0001). The mean retinal sensitivity loss of the sham group was 45% greater than that of the treated group (decrease, 15.81+/-8.93 dB; P = 0.07). Reading speed deteriorated in the sham group (-13.9 words per minute) with no loss in the treated group (P = 0.02). Serious adverse ocular effects were found in 2 of 51 persons (4%) in the sham group and 2 of 48 persons (4%) in the treated group. CONCLUSIONS: In participants with macular telangiectasia type 2, a surgical implant that released CNTF into the vitreous cavity, compared with a sham procedure, slowed the progression of retinal degeneration. Further research is needed to assess longer term clinical outcomes and safety. PMID- 30292542 TI - Risk of Systemic Adverse Events Associated with Intravitreal Anti-VEGF Therapy for Diabetic Macular Edema in Routine Clinical Practice. AB - PURPOSE: Intravitreal anti-vascular endothelial growth factor (VEGF) pharmacotherapy has become standard of care for the management of diabetic macular edema (DME). The systemic safety profile of this treatment in routine clinical practice remains incompletely understood. We used a large claims database to investigate the risk of systemic serious adverse events (SAEs) in patients receiving anti-VEGF for DME compared with controls treated with macular laser photocoagulation or intravitreal corticosteroid. DESIGN: Retrospective cohort study. PARTICIPANTS: By using a large U.S. insurance database, we identified privately insured and Medicare Advantage patients aged >=18 years treated with anti-VEGF for DME between January 1, 2006, and December 31, 2015, along with control patients receiving macular laser or corticosteroid. We included patients with 1 year of medical coverage before initial DME treatment. METHODS: We assessed associations between treatment modalities and predefined systemic outcomes using Cox proportional hazards regression. We performed 2 separate comparisons, one between anti-VEGF and macular laser and one between anti-VEGF and corticosteroid. We used inverse propensity score weighting for the first comparison to account for treatment selection bias. For the second, we used 2:1 propensity score matching on demographics, year, and baseline comorbidities because of the smaller number of corticosteroid-treated patients. MAIN OUTCOME MEASURES: Risk of cerebrovascular disease, myocardial infarction, major bleeding, and all-cause hospitalization occurring within 6 months of initial DME treatment as hazard ratios (HRs) with 95% confidence intervals (CIs). RESULTS: A total of 23 348 patients receiving treatment for DME met inclusion criteria; 13 365 received macular laser, 9219 received intravitreal anti-VEGF, and 764 received intravitreal corticosteroid as initial treatment. Anti-VEGF pharmacotherapy was not associated with an increased hazard of cerebrovascular disease (HR, 0.96; 95% CI, 0.65-1.41; P = 0.83), major bleeding (HR, 1.23; 95% CI, 0.76-1.99; P = 0.41), or myocardial infarction (HR, 1.03; 95% CI, 0.73-1.44; P = 0.88) when compared with macular laser for DME; however, there was an increased hazard of post treatment all-cause hospital admission (HR, 1.17; 95% CI, 1.05-1.30; P = 0.01). The rates of all primary systemic SAE outcomes were similar after treatment with anti-VEGF versus corticosteroid (P > 0.05 for all). CONCLUSIONS: We identified no increased risk of cerebrovascular disease, myocardial infarction, or major bleeding within 6 months after intravitreal anti-VEGF pharmacotherapy for the treatment of DME in routine clinical practice. A potential difference in all cause hospitalization may merit further investigation. PMID- 30292543 TI - The analysis of cell-free DNA concentrations and integrity in serum of initial and treated of lymphoma patients. AB - OBJECTIVE: To evaluate cell-free DNA (cfDNA) in plasma as a promising biomarker for lymphoma, altered levels of cfDNA and its association with clinical parameters are investigated in patients suffered from lymphomas. METHODS: Peripheral blood specimens were collected from 60 patients with lymphoma during initial diagnosis and those of another 107 patients with lymphoma during treated stage were also collected, 93 healthy volunteers were selected as control group. Quantitative PCR was used to detect cfDNA level in each group, cfDNA level in different groups was analyzed to understand its relationship with lymphoma patients' clinical features. After correlation analysis between cfDNA and clinical characteristics, Receiver operator characteristic curve was performed to analyze sensitivity and specificity of cfDNA and LDH. RESULTS: cfDNA concentration and integrity in initial stage of lymphoma patients were significantly higher than those in treated stage, and cfDNA concentration in treated phase was significantly higher than cfDNA concentration in control group. There was no significant difference in cfDNA integrity at treated stage compared with control group. There was no significant correlation between patient's age, gender, extranodal invasion and lymphoma pathological type and cfDNA concentration and integrity; In contrast, there was a significant correlation between ECOG score, LDH content, Ann Arbor stage, IPI, B-symptoms, Ki-67 expression and radiotherapy and cfDNA concentration and integrity, both at the time of initial diagnosis and treated stage. cfDNA concentration detection is an optimal diagnostic indicator, followed by cfDNA integrity detection, the sensitivity and specificity of both are superior to the traditional LDH detection. CONCLUSION: cfDNA level is significantly increased in lymphomas patient plasma and may help lymphoma screening. cfDNA level may serve as a potential indicator of lymphomas treatment efficacy. PMID- 30292544 TI - Short communication: Effect of refrigerated storage on the pH and bacterial content of pasteurized human donor milk. AB - Once pasteurized donor milk is thawed for its administration to a preterm or sick neonate, and until it is administered, it is kept refrigerated at 4 to 6 degrees C for 24 h. After this time, unconsumed milk is discarded. This time has not been extended, primarily because of the concern of bacterial contamination. The aim of this study was to determine the changes in pH and bacterial count when pasteurized donor milk was kept under refrigeration for a prolonged period (14 d). In this prospective study, 30 samples of pasteurized donor milk from 18 donors were analyzed. Milk was handled following the regular operating protocols established in the neonatal unit and was kept refrigerated after thawing. pH measurements and bacteriology (on blood agar and MacConkey agar plates) were performed on each sample at time 0 (immediately after thawing) and then every day for 14 d. Changes in pH of samples over time were evaluated with linear mixed effects regression models. A slow but gradual increase in milk pH was observed starting from the first day [mean (+/-SD) pH of 7.30 (+/-0.18) at time 0 and 7.69 (+/-0.2) on d 14]. No bacterial growth was observed in any of the samples throughout the complete trial except in one sample, in which Bacillus flexus was isolated. In conclusion, pasteurized human donor milk maintains its microbiological quality when properly handled and refrigerated (4-6 degrees C). The slight and continuous increase in milk pH after the first day could be due to changes in the solubility of calcium and phosphate during refrigerated storage. PMID- 30292545 TI - Supplementation effects of pomegranate by-products on oxidative status, metabolic profile, and performance in transition dairy cows. AB - Recent studies demonstrated a high antioxidant capacity for pomegranate components due to their rich bioactive compounds, such as conjugated fatty acids and phenolics. The objective of the present study was, therefore, to assess whether pomegranate seed or pomegranate seed pulp (peel + seed) supplementation could be effective to improve antioxidant status, and hence metabolic profile and performance in periparturient dairy cows. After a 1-wk pretreatment period, Holstein cows (primiparous n = 12, multiparous n = 18) were assigned to 3 dietary treatments from 25 d before expected calving through 25 d postcalving. The dietary treatments included (1) control (CON); (2) diet supplemented with pomegranate seeds (PS; 400 g/cow per day); and (3) diet supplemented with pomegranate seed pulp (PSP; 400 g of seeds/cow per day + 1200 g of peels/cow per day). Compared with CON, supplementation with either PS or PSP had no effects on dry matter intake, rumen fermentation, and plasma concentrations of cholesterol, total protein, globulin, and aspartate amino transferase, but enhanced plasma total antioxidant activity, and lowered triacylglycerol, free fatty acids (FFA), and beta-hydroxybutyrate at both pre- and postpartum periods. Plasma concentration of glucose, albumin, malondialdehyde (MDA) and blood superoxide dismutase (SOD) activity were not affected by dietary treatments at prepartum, whereas SOD activity increased and glucose, albumin, MDA, and FFA-to-albumin ratio decreased by feeding both by-products at postpartum period. In contrast to PS, supplementing PSP resulted in a greater decrease in plasma glucose and triacylglycerol concentration and higher increase in SOD activity. Energy- and fat-corrected milk yields were higher in cows fed PSP diet compared with those fed CON or PS diets, but content of milk fat, protein, and lactose were similar across the dietary treatments. These findings indicated that dietary pomegranate by-products supplementation, in particular PSP, could improve antioxidant status, which was associated with a decline in lipid oxidation (FFA and beta hydroxybutyrate) and peroxidation (MDA) and an enhancement in glucose utilization as well as fat-corrected milk yield. PMID- 30292546 TI - Estimation of circulating bovine leukemia virus levels using conventional blood cell counts. AB - Bovine leukemia virus (BLV) is widely prevalent in Japanese dairy farms. To control BLV infections in Japan, segregating or managing cows according to their proviral load (PVL) is a rational strategy. This study was conducted to establish a quantitative procedure for estimating blood PVL per microliter using a statistical model to offer a cost-effective alternative to the conventional quantitative real-time PCR method. In total, 250 Holstein cows infected with BLV were identified from 10 commercial dairy farms. Information on age was collected and blood samples were tested for white blood cell and lymphocyte counts and PVL using PCR. Generalized linear models with quasi-Poisson errors were used to estimate PVL by selecting age, logarithm of lymphocyte count, and their interaction term as explanatory variables. To evaluate the model, blood samples of 92 BLV-infected Holstein cows from 2 other commercial dairy farms were tested, and measured PVL values were compared with estimated PVL values by the model. The logPVL per microliter was modeled by positive associations with log lymphocyte count and age and a negative association with the interaction term. In the evaluation, measured PVL values had a strong correlation with estimated PVL values (Spearman's rho = 0.87). In conclusion, our model provides a cost effective and more rapid alternative to the conventional method to facilitate test and segregation or management of BLV-suspected cows. PMID- 30292547 TI - Short communication: Multi-component interactions causing solidification during industrial-scale manufacture of pre-crystallized acid whey powders. AB - Acid whey (AW) is the liquid co-product arising from acid-induced precipitation of casein from skim milk. Further processing of AW is often challenging due to its high mineral content, which can promote aggregation of whey proteins, which contributes to high viscosity of the liquid concentrate during subsequent lactose crystallization and drying steps. This study focuses on mineral precipitation, protein aggregation, and lactose crystallization in liquid AW concentrates (~55% total solids), and on the microstructure of the final powders from 2 independent industrial-scale trials. These AW concentrates were observed to solidify either during processing or during storage (24 h) of pre-crystallized concentrate. The more rapid solidification in the former was associated with a greater extent of lactose crystallization and a higher ash-to-protein ratio in that concentrate. Confocal laser scanning microscopy analysis indicated the presence of a loose network of protein aggregates (<=10 um) and lactose crystals (100-300 um) distributed throughout the solidified AW concentrate. Mineral-based precipitate was also evident, using scanning electron microscopy, at the surface of AW powder particles, indicating the formation of insoluble calcium phosphate during processing. These results provide new information on the composition- and process dependent physicochemical changes that are useful in designing and optimizing processes for AW. PMID- 30292548 TI - Optimized cultural conditions of functional yogurt for gamma-aminobutyric acid augmentation using response surface methodology. AB - Yogurt, a functional dairy food product, is an effective medium for delivering beneficial functional ingredients. One ingredient, gamma-aminobutyric acid (GABA), has growing appeal in the development of functional foods for its potential in reducing the risk of diabetes, hypertension, and stress as a bioactive agent. However, the concentration of GABA in existing food products is remarkably low. We developed a functional yogurt rich in GABA using Streptococcus thermophilus fmb5. The GABA yield of yogurt was enhanced by optimization of culture conditions using single factor and response surface methods. The results showed that culture temperature, monosodium glutamate concentration, and culture time are the 3 main factors that affect GABA yield. The optimal culture conditions were determined as follows: 38.8 degrees C for culture temperature, 20 g/L of monosodium glutamate, and 120 h of culture time. Under the above optimal conditions, the actual yield of GABA production was maximized at 9.66 g/L, which was 1.2 times or higher than that of from any single factor treatment. The GABA concentration, viable bacteria number, and water-holding capacity of GABA-rich yogurt were stable throughout the whole storage time. The results show that producing yogurt with Streptococcus thermophilus fmb5 and the optimized culture conditions will achieve high GABA concentrations that maximize health benefits to consumers. PMID- 30292549 TI - Randomized clinical trial to evaluate the efficacy of prostaglandin F2alpha to treat purulent vaginal discharge in lactating dairy cows. AB - The objectives of this study were (1) to assess the effect of purulent vaginal discharge (PVD) on reproductive performance using a 4-point vaginal discharge score (VDS) and (2) to evaluate the effect of PGF2alpha treatment in cows with PVD on reproductive performance. Holstein cows (n = 2,473) from 1 commercial dairy farm had their vaginal discharge scored at 32 +/- 3 d in milk (DIM) using a 4-point scale. Cows were also scored for body condition score and had their ovaries examined using transrectal ultrasound. A VDS-2 or greater was used to define PVD. Cows with PVD were assigned to receive 2 doses of 500 ug of PGF2alpha analogue (n = 277; Cloprostenol; PGF Veyx forte, Veyx Pharma Ltd., Schwarzenborn, Germany) 14 d apart (odd ear tag number) or remained untreated (n = 272; even ear tag number). All cows not detected in estrus at 90 +/- 3 DIM were enrolled into a timed artificial insemination (AI) protocol. The effect of VDS and the effect of PGF2alpha in cows with PVD on reproductive performance were evaluated separately. First service conception risk (FSCR), time to first AI, and time to pregnancy were used as indicators for reproductive performance. Data were analyzed with Cox's regression and mixed logistic models. The prevalence of PVD was 22.2% (548/2,473). We detected an interaction of parity and VDS for FSCR and time to pregnancy. In primiparous cows, VDS had no effect on FSCR and time to pregnancy. In multiparous cows, VDS had an effect on FSCR and time to pregnancy. Multiparous cows having a VDS-2 or a VDS-3 had decreased odds of pregnancy at first AI compared with cows having a VDS-0. Multiparous cows with VDS-1 or VDS-3 had a decreased hazard of conceiving within 200 DIM. The treatment effect of PGF2alpha was conditional on parity. In primiparous animals with PVD without a corpus luteum present at 32 DIM, treatment with PGF2alpha reduced FSCR. Irrespective of the presence of a corpus luteum, treatment with PGF2alpha decreased the hazard of conceiving within 200 DIM in primiparous cows. Although multiparous cows with PVD treated with PGF2alpha had increased odds of pregnancy at first AI, no treatment effect was observed on the hazard of conceiving within 200 DIM. Our results do not support the blanket use of PGF2alpha as a treatment option in postpartum dairy cows having PVD. PMID- 30292550 TI - Production of dairy cows fed distillers dried grains with solubles in low- and high-forage diets. AB - The objective of the study was to investigate the effects of dietary forage and distillers dried grains with solubles (DDGS) concentration on the performance of lactating dairy cows. Twelve Holstein cows were blocked by parity and milk production and assigned to replicated 4 * 4 Latin squares with a 2 * 2 factorial arrangement of treatments. Diets were formulated to contain low forage [LF; 17% forage neutral detergent fiber (NDF)] or high forage (HF; 24.5% forage NDF) and DDGS at 0 or 18% of diet dry matter. The forage portion of the diet consisted of 80% corn silage and 20% alfalfa hay (dry matter basis). A portion of the ground corn and all of the expeller soybean meal and extruded soybeans from 0% DDGS diets were replaced with DDGS to formulate 18% DDGS diets. Overall, we found no interactions of forage * DDGS concentrations for any of the production measures. We observed no effect of diet on dry matter intake. Milk yield was greater when cows were fed LF diets compared with HF diets (43.3 vs. 41.5 kg/d). Milk fat concentration (3.03 vs. 3.38%) was lower for cows fed LF diets compared with HF diets, whereas protein concentration (3.11 vs. 2.98%) and yield (1.34 vs. 1.24 kg/d) were greater for cows fed LF diets compared with HF diets. Yields of fat, total solids, energy-corrected milk, and feed efficiency were not affected by diets. Cows partitioned equally for milk, maintenance, and body reserves. Replacing starch from ground corn and protein from soybean feeds with DDGS at either 17 or 24.5% of forage NDF concentration in the diet was cost-effective and did not affect the production performance of lactating dairy cows. PMID- 30292551 TI - Lactobacillus paracasei ssp. paracasei YBJ01 reduced d-galactose-induced oxidation in male Kuming mice. AB - We investigated in vitro and in vivo antioxidant activity of Lactobacillus paracasei ssp. paracasei YBJ01 (LPSP-YBJ01) isolated and identified from fermented yogurt. Strain LPSP-YBJ01 had stress tolerance against acidity, bile salt, and osmotic pressure. Five in vitro antioxidant assays were used to evaluate antioxidant activity of LPSP-YBJ01, which could scavenge free radicals (2,2-diphenyl-1-picrylhydrazyl and hydroxyl) and superoxide anion in vitro. In addition, strain LPSP-YBJ01 had stronger antilipid peroxidation activity and weak reducing power in vitro. We measured in vivo antioxidant activity of LPSP-YBJ01 in an oxidation mouse model induced by d-galactose injection. Strain LPSP-YBJ01 significantly increased serum superoxide dismutase (SOD), glutathione peroxidase, and total-antioxidant capability, and inhibited generation of malondialdehyde in a dose-dependent manner. In addition, strain LPSP-YBJ01 also increased the hepatic and splenic protein expressions of some antioxidant enzymes such as catalase, Cu/Zn-SOD, and Mn-SOD in mice treated with d-galactose. Thus, LPSP YBJ01 had antioxidant activity in vitro and in vivo and may be a useful probiotic. PMID- 30292552 TI - Is rumination time an indicator of methane production in dairy cows? AB - As long as large-scale recording of expensive-to-measure and labor-consuming traits, such as dry matter intake (DMI) and CH4 production (CH4P), continues to be challenging in practical conditions, alternative traits that are already routinely recorded in dairy herds should be investigated. An ideal indicator trait must, in addition to expressing genetic variation, have a strong correlation with the trait of interest. Our aim was to estimate individual level and phenotypic correlations between rumination time (RT), CH4P, and DMI to determine if RT could be used as an indicator trait for CH4P and DMI. Data from 343 Danish Holstein cows were collected at the Danish Cattle Research Centre for a period of approximately 3 yr. The data set consisted of 14,890 records for DMI, 15,835 for RT, and 6,693 for CH4P. Data were divided in primiparous cows only (PC) and all cows (MC), and then divided in lactation stage (early, mid, late, and whole lactation) to analyze the changes over lactation. Linear mixed models, including an animal effect but no pedigree, were used to estimate the correlations among traits. Phenotypic and individual level correlations between RT and both CH4P and DMI were close to zero, regardless of lactation stage and data set (PC or MC). However, CH4P and DMI were highly correlated, both across lactation stages and data sets. In conclusion, RT is unsuitable to be used as an indicator trait for either CH4P or DMI. Our study failed to validate RT as a useful indicator trait for both CH4P and DMI, but more studies with novel phenotypes can offer different approaches to select and incorporate important yet difficult to record traits into breeding goals and selection indexes. PMID- 30292553 TI - Invited review: Microbiota of the bovine udder: Contributing factors and potential implications for udder health and mastitis susceptibility. AB - Various body sites of vertebrates provide stable and nutrient-rich ecosystems for a diverse range of commensal, opportunistic, and pathogenic microorganisms to thrive. The collective genomes of these microbial symbionts (the microbiome) provide host animals with several advantages, including metabolism of indigestible carbohydrates, biosynthesis of vitamins, and modulation of innate and adaptive immune systems. In the context of the bovine udder, however, the relationship between cow and microbes has been traditionally viewed strictly from the perspective of host-pathogen interactions, with intramammary infections by mastitis pathogens triggering inflammatory responses (i.e., mastitis) that are often detrimental to mammary tissues and cow physiology. This traditional view has been challenged by recent metagenomic studies indicating that mammary secretions of clinically healthy quarters can harbor genomic markers of diverse bacterial groups, the vast majority of which have not been associated with mastitis. These observations have given rise to the concept of "commensal mammary microbiota," the ecological properties of which can have important implications for understanding the pathogenesis of mastitis and offer opportunities for development of novel prophylactic or therapeutic products (or both) as alternatives to antimicrobials. Studies conducted to date have suggested that an optimum diversity of mammary microbiota is associated with immune homeostasis, whereas the microbiota of mastitic quarters, or those with a history of mastitis, are considerably less diverse. Whether disruption of the diversity of udder microbiota (dysbiosis) has a role in determining mastitis susceptibility remains unknown. Moreover, little is known about contributions of various biotic and abiotic factors in shaping overall diversity of udder microbiota. This review summarizes current understanding of the microbiota within various niches of the udder and highlights the need to view the microbiota of the teat apex, teat canal, and mammary secretions as interconnected niches of a highly dynamic microbial ecosystem. In addition, host-associated factors, including physiological and anatomical parameters, as well as genetic traits that may affect the udder microbiota are briefly discussed. Finally, current understanding of the effect of antimicrobials on the composition of intramammary microbiota is discussed, highlighting the resilience of udder microbiota to exogenous perturbants. PMID- 30292554 TI - Immunoreactive properties of alpha-casein and kappa-casein: Ex vivo and in vivo studies. AB - The aim of this study was to evaluate the ex vivo and in vivo studies immune potential of alpha- and kappa-casein. Ex vivo, naive mouse splenocytes were stimulated with alpha- or kappa-casein. After 120 h of culture, the proliferation index (PI), determined by 3-(4,5 dimethylthiazol-2yl)-2,5-diphenyl tetrazolium bromide (MTT) assay and carboxyfluorescein diacetate N-succinimidyl ester (CFSE) staining, did not vary for either antigen, suggesting similar ex vivo immunogenic potential of both casein fractions. In vivo, BALB/ccmdb mice were sensitized with alpha- or kappa-casein and then gavaged with primary antigen. Mice immunized with alpha-casein had higher levels of IgG (216.33) and IgA (210.22) in serum at the end of the experiment compared with mice immunized with kappa-casein (215 and 29.3 for IgG and IgA, respectively). The use of alpha-casein for mouse immunization and ex vivo lymphocyte stimulation resulted in higher concentrations of secreted cytokines (IL-4, IL-10) compared with kappa-casein stimulation. This is consistent with increasing regulatory T cell (Treg) lymphocyte populations, independent of the antigen used for stimulation. In summary, the immunogenic potential of alpha- and kappa-casein was similar. Humoral and cellular immune responses confirmed their strong, independent potential to induce B and T cells. We propose that the lymphocyte proliferation index be used as an initial screening for protein immunogenicity.

AB - Many veal calves arrive to growing facilities with diseases, including diarrhea and navel inflammation. Observing neonatal calf behavior, such as lying behavior, can be used to better detect and determine the implications of these diseases. The aim of this study was to determine the effect of navel inflammation and diarrhea on lying behavior in neonatal veal calves. This study was part of a larger experiment that included a total of 360 male Holstein calves from 3 cohorts; from these calves, we selected a subset of 125 calves (every third calf as they entered the barn) to be fitted with 3-dimensional accelerometers (Hobo Pendant G data loggers; Onset Computer Corp., Bourne, MA) on 1 hind leg to continuously measure lying time, number of lying bouts, and lying bout duration. Calves were housed individually on slatted flooring (Tenderfoot; Tandem Products Inc., Minneapolis, MN) in 3 rooms of a mechanically ventilated barn. Health exams were conducted twice weekly for 2 wk starting the day after arrival. Exams included rectal temperature, navel score (0 = normal, 1 = mildly inflamed, 2 = moderately inflamed, 3 = severely inflamed), and fecal score (0 = normal, 1 = semiformed, 2 = loose, 3 = watery). Calves were considered to have navel inflammation (n = 22) or diarrhea (n = 15) if they scored >=2 during at least 3 of the 4 health exams. The lying behavior of these calves was compared with that of normal calves (n = 18) that had no signs of illness and rectal temperatures <39.4 degrees C during at least 3 of the 4 health exams. Data were analyzed using a repeated-measures ANOVA; models included cohort (1, 2, or 3), health status (normal, navel inflammation, or diarrhea), week (1 or 2), and a health by week interaction. There was an effect of health status on lying time, whereby normal calves spent more time lying compared with calves with inflamed navels and tended to spend more time lying compared with calves with diarrhea. There was no effect of health status on the number of lying bouts per day or on the duration of lying bouts. There were no health by week interactions. Results indicate that neonatal veal calves with navel inflammation and diarrhea may be less comfortable than calves without these conditions. Veal producers should consider adapting their facilities to create more comfortable lying environments to help calves better recover from disease, such as by adding a hospital pen with comfortable bedding. PMID- 30292556 TI - Effects of dry period energy intake on insulin resistance, metabolic adaptation, and production responses in transition dairy cows on grass silage-based diets. AB - High energy intake in the dry period has reportedly had adverse effects on mobilization of body reserves, dry matter intake, and productivity of dairy cows. We investigated whether grass silage (GS) fed ad libitum (high energy intake, HEI; 141% of daily metabolizable energy requirements) in an 8-wk dry period affects metabolic adaptation-specifically, peripheral insulin resistance-compared with a total mixed ration consisting of GS, wheat straw, and rapeseed meal (55/40/5%; controlled energy intake, CEI; 108% of metabolizable energy/d) fed ad libitum. Multiparous Ayrshire dairy cows (n = 16) were used in a randomized complete block design until 8 wk after parturition. Commercial concentrates were fed 1 and 2 kg/d during the last 10 to 6 and 5 to 0 d before the expected calving date, respectively. Postpartum, a similar lactation diet with ad libitum access to GS and increasing concentrate allowance (maximum of 16 kg/d) was offered to all. The HEI group gained more body weight and had higher plasma insulin, glucose, and beta-hydroxybutyrate concentrations than the CEI group prepartum. Postpartal plasma glucose tended to be higher and milk yield was greater from wk 5 onward for HEI compared with CEI cows. An intravenous glucose tolerance test (IVGTT) was performed at -13 +/- 5 d and 9 +/- 1 d relative to calving. The HEI cows had greater insulin response to glucose load and smaller area under the response curve for glucose than CEI cows in prepartal IVGTT. Thus, compensatory insulin secretion adapted to changes in insulin sensitivity of the peripheral tissues, preserving glucose tolerance of HEI cows. Higher insulin levels were needed in HEI cows than in CEI cows to elicit a similar decrement of nonesterified fatty acid concentration in prepartal IVGTT, suggesting reduced inhibition of lipolysis by insulin in HEI cows before parturition. In conclusion, high energy intake of moderately digestible GS with low concentrate feeding in the close-up dry period did not have adverse effects on metabolic adaptation, insulin sensitivity, and body mobilization after parturition. Instead, this feeding regimen was more beneficial to early-lactation performance than GS-based total mixed ration diluted with wheat straw. PMID- 30292557 TI - Characteristics of diffusion-weighted images and apparent diffusion coefficients of ranulas and other masses in and around the floor of the mouth. AB - OBJECTIVE: The aim of this study was to evaluate the characteristics of diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) values of ranulas. In addition, to elucidate DWI findings and ADC values of other representative masses in and around the floor of the mouth. STUDY DESIGN: DWI findings and ADC values in 35 patients with ranulas and 33 patients with other masses were retrospectively reviewed with a central focus on cystic masses or lesions that may have cyst-like components in and around the floor of the mouth based on the diagnosis of each respective disease. RESULTS: Ranulas were all well defined, homogeneous masses with high signal intensity on DWI. The mean +/- standard deviation ADC value of the 35 ranulas was 2.59 +/- 0.31 * 10-3 mm2/s. There was a significant difference in ADC values between simple and plunging ranulas. On DWI, most other masses were heterogeneous, and most ADC values, except those for thyroglossal duct cysts, hemangiomas, and pleomorphic adenomas, were significantly lower than those for ranulas. CONCLUSIONS: The characteristic DWI and ADC findings of ranulas can be determined accurately, and these data can be significantly useful in the differential diagnosis of many kinds of diseases in and around the oral floor.

PMID- 30292559 TI - Normalizing glucocorticoid levels attenuates metabolic and neuropathological symptoms in the R6/2 mouse model of huntington's disease. AB - Huntington's disease (HD) is a fatal genetic neurological disorder caused by a mutation in the human Huntingtin (HTT) gene. This mutation confers a toxic gain of function of the encoded mutant huntingtin (mHTT) protein, leading to widespread neuropathology including the formation of mHTT-positive inclusion bodies, gene dysregulation, reduced levels of adult dentate gyrus neurogenesis and neuron loss throughout many regions of the brain. Additionally, because HTT is ubiquitously expressed, several peripheral tissues are also affected. HD patients suffer from progressive motor, cognitive, psychiatric, and metabolic symptoms, including weight loss and skeletal muscle wasting. HD patients also show neuroendocrine changes including a robust, significant elevation in circulating levels of the glucocorticoid, cortisol. Previously, we confirmed that the R6/2 mouse model of HD exhibits elevated corticosterone (the rodent homolog of cortisol) levels and demonstrated that experimentally elevated corticosterone exacerbates R6/2 HD symptomology, resulting in severe and rapid weight loss and a shorter latency to death. Given that efficacious therapeutics are lacking for HD, here we investigated whether normalizing glucocorticoid levels could serve as a viable therapeutic approach for this disease. We tested the hypothesis that normalizing glucocorticoids to wild-type levels would ameliorate HD symptomology. Wild-type (WT) and transgenic R6/2 mice were allocated to three treatment groups: 1) adrenalectomy with normalized, WT-level corticosterone replacement (10 MUg/ml), 2) adrenalectomy with high HD-level corticosterone replacement (35 MUg/ml), or 3) sham surgery with no corticosterone replacement. Normalizing corticosterone to WT levels led to an improvement in metabolic rate in male R6/2 mice, as indicated by indirect calorimetry, including a reduction in oxygen consumption and normalization of respiratory exchange ratio values (p < .05 for both). Normalizing corticosterone also ameliorated brain atrophy in female R6/2 mice and skeletal muscle wasting in both male and female R6/2 mice (p < .05 for all). Female R6/2 mice given WT-level corticosterone replacement also showed a reduction in HD neuropathological markers, including a reduction in mHTT inclusion burden in the striatum, cortex, and hippocampus (p < .05 for all). This data illustrates that ameliorating glucocorticoid dysregulation leads to a significant improvement in HD symptomology in the R6/2 mouse model and suggests that cortisol-reducing therapeutics may be of value in improving HD patient quality of life. PMID- 30292560 TI - Venomous Snakebites in Canada: A National Review of Patient Epidemiology and Antivenom Usage. AB - INTRODUCTION: There are 3 pit viper species in Canada. Limited Canadian literature exists on the epidemiology of venomous snakebites and the treatment patterns with antivenom. This study described the epidemiology, the utilization of antivenom, and estimated expenditures due to forfeited antivenom for pit viper envenomations in Canada. METHODS: A retrospective review of the Health Canada Special Access Program records to generate descriptive statistics. Data are presented as mean+/-SD (range), as appropriate. RESULTS: The geographic distribution of Canadian pit viper species is presented. There were 99 envenomations reported in Canada from January 2009 to December 2015. The number of envenomations per year was 14+/-6 (6-21). CroFab and Antivipmyn are used in Canada to treat envenomations. The number of vials for patient treatment was 17+/ 12 (3-66) and 16+/-9 (6-42) for CroFab and Antivipmyn, respectively. Antivenom stock usage for patient treatment varied across the country with provincial means reported for British Columbia (33%), Alberta (37%), Saskatchewan (27%), and Ontario (71%). The costs incurred secondary to forfeited stock where estimated as: $1,280,000 USD in British Columbia, $255,000 in Alberta, $60,000 in Saskatchewan, and $0 in Ontario. CONCLUSIONS: The absolute number of annual envenomations is small and the 3 Crotalinae species are limited to relatively narrow geographic areas in British Columbia, Alberta, Saskatchewan, and Ontario. The utilization of antivenom in the treatment of patients revealed that regions where the western and prairie rattlesnake reside forfeited a substantial amount of antivenom from 2009 to 2015. Organizations responsible for maintaining antivenom supplies on a provincial or regional level could use these data to guide antidote stocking and reduce costs. PMID- 30292562 TI - NR3C2 Gene is Associated with Susceptibility to High-Altitude Pulmonary Edema in Han Chinese. AB - INTRODUCTION: The mineralocorticoid receptor is encoded by the NR3C2 gene and plays an important role in regulating vascular tone in high-altitude pulmonary edema (HAPE). This study aimed to investigate the association of the polymorphisms in the NR3C2 gene with HAPE susceptibility in Han Chinese. METHODS: We enrolled 133 HAPE patients and 131 matched healthy Han Chinese from the Yushu area in Qinghai, where the altitude is greater than 3500 m. Two single nucleotide polymorphisms (SNPs) of the NR3C2 gene, rs2070951 and rs5522, were genotyped by the Sequenom MassARRAY SNP assay. RESULTS: The genotypic distributions and allele frequencies of NR3C2 SNP rs5522 were significantly different between the HAPE and control groups (P<0.05). The frequency of the A allele of rs5522 was significantly higher in the HAPE group than in the control group (P<0.05) with an odds ratio of 1.7 (95% CI: 1.0-2.8). There were no significant differences in the genotypic distributions and allele frequencies of NR3C2 SNP rs2070951 between the HAPE and control groups. The frequencies of the C-A and C-G haplotypes were significantly higher in the HAPE group than in control group. CONCLUSIONS: The rs5522 polymorphism of the NR3C2 gene was associated with HAPE susceptibility in Chinese subjects. The A allele may contribute to the susceptibility to HAPE. The frequency of the C-A and C-G haplotypes of rs2070951 and rs5522 in the NR3C2 gene may increase the risk of HAPE. PMID- 30292563 TI - High Altitude Illness: Knowledge, Practice, and Attitudes of Porters in Nepal. AB - INTRODUCTION: Porters working at high altitude face a number of preventable health risks ranging from frostbite to potentially fatal high-altitude pulmonary and cerebral edema. Porters are often recruited from impoverished low-altitude areas, poorly equipped in terms of protective clothing, and tasked with carrying loads that equal or exceed their body mass to high elevations. Despite a large population of porters working throughout mountainous parts of the world, there is little documentation regarding knowledge levels, attitudes, and practices related to the prevention of altitude illness in this population. Much of the literature focuses on biomechanics of load carrying for porters or altitude issues for trekkers. METHODS: A cross-sectional survey was developed using a modified Delphi technique. The survey was administered to a convenience sample of porters (n=146) from diverse cultural groups between Lukla (2774 m) and Everest Base Camp (5361 m). RESULTS: Many of the porters started at a young age, carried heavy loads, and had difficulty identifying symptoms of high altitude illness, and less than 20% correctly identified preventive measures for high-altitude illness. CONCLUSIONS: Porters in the Khumbu region continue to face hazards in their working environment. Future research and health education campaigns should address knowledge deficits and help with the design of tailored interventions. PMID- 30292564 TI - Discrimination of Pulmonary Nodule Volume Change for Low- and High-contrast Tasks in a Phantom CT Study with Low-dose Protocols. AB - RATIONALE AND OBJECTIVES: The quantitative assessment of volumetric CT for discriminating small changes in nodule size has been under-examined. This phantom study examined the effect of imaging protocol, nodule size, and measurement method on volume-based change discrimination across low and high object to background contrast tasks. MATERIALS AND METHODS: Eight spherical objects ranging in diameter from 5.0 mm to 5.75 mm and 8.0 mm to 8.75 mm with 0.25 mm increments were scanned within an anthropomorphic phantom with either foam-background (high contrast task, ~1000 HU object to background difference)) or gelatin-background (low-contrast task, ~50 to 100 HU difference). Ten repeat acquisitions were collected for each protocol with varying exposures, reconstructed slice thicknesses and reconstruction kernels. Volume measurements were obtained using a matched-filter approach (MF) and a publicly available 3D segmentation-based tool (SB). Discrimination of nodule sizes was assessed using the area under the ROC curve (AUC). RESULTS: Using a low-dose (1.3 mGy), thin-slice (<=1.5 mm) protocol, changes of 0.25 mm in diameter were detected with AU = 1.0 for all baseline sizes for the high-contrast task regardless of measurement method. For the more challenging low-contrast task and same protocol, MF detected changes of 0.25 mm from baseline sizes >=5.25 mm and volume changes >=9.4% with AUC>=0.81 whereas corresponding results for SB were poor (AUC within 0.49-0.60). Performance for SB was improved, but still inconsistent, when exposure was increased to 4.4 mGy. CONCLUSION: The reliable discrimination of small changes in pulmonary nodule size with low-dose, thin-slice CT protocols suitable for lung cancer screening was dependent on the inter-related effects of nodule to background contrast and measurement method. PMID- 30292565 TI - Dermal injuries caused by purse seine capture result in lasting physiological disturbances in coho salmon. AB - Fish vitality can be measured by classifying reflex impairments (i.e., a visual impression of the ability to respond to induced stimuli) and visible injuries. These metrics can predict survival probability following release from fisheries, and monitoring physiological disturbances following capture can help understand mechanisms of mortality. To test the hypothesis that severity of injury and reflex impairment influences the time course of physiological recovery, coho salmon (Oncorhynchus kisutch) were held for up to 84-h following capture by purse seine. We classified reflex impairments and visible dermal injuries, and through repeated blood sampling, assessed metrics indicative of stress, exhaustion, and osmoregulatory disturbances. Reflex-impairments and blood lactate levels suggested fish were exhausted upon capture but recovered after 48 h. Conversely, fish with dermal injuries showed disruptions to ion homeostasis that were greater in more severely injured fish and increased over time. While reflex impairments may predict short term post-release mortality, the prolonged physiological disturbances caused by dermal injuries are likely to be responsible for delayed mortality; our results suggest that disruptions to ion homeostasis is a possible mechanism of post-release mortality. PMID- 30292566 TI - Association between diastolic cardiac dysfunction and nonalcoholic fatty liver disease: A systematic review and meta-analysis. AB - BACKGROUND/OBJECTIVES: Recent studies have suggested an association between nonalcoholic fatty liver disease (NAFLD) and diastolic cardiac dysfunction, although the results were inconsistent. This study was conducted to investigate this possible association. METHODS: A comprehensive literature review was conducted utilizing the MEDLINE and Embase databases from inception through May 2018 to identify all cross-sectional studies that compared the prevalence of diastolic cardiac dysfunction among patients with NAFLD to individuals without NAFLD. Effect estimates from each study were extracted and combined using the random-effect, generic inverse variance method of DerSimonian and Laird. RESULTS: A total of 12 studies with 280,645 participants fulfilled the eligibility criteria and were included in the meta-analysis. There was a significant association between NAFLD and diastolic cardiac dysfunction with a pooled odds ratio (OR) of 2.02 (95% confidence interval (CI), 1.47-2.79; I2 89%). Subgroup analysis based on the country of origin continued to demonstrate a significant association in subgroups of both Western and Eastern countries with pooled ORs of 1.76 (95% CI, 1.14-2.72; I2 85%) and 2.59 (95% CI, 1.42-4.69; I2 87%), respectively. Limitations included high between-study heterogeneity, lack of unified definition of diastolic dysfunction and presence of publication bias. CONCLUSIONS: A significant association between diastolic cardiac dysfunction and NAFLD was observed in this meta-analysis. This observation could suggest the need for careful cardiovascular surveillance among patients with NAFLD. PMID- 30292567 TI - Sex differences in psychomotor development during the preschool period: A longitudinal study of the effects of environmental factors and of emotional, behavioral, and social functioning. AB - We sought to determine the extent to which sex differences in psychomotor development during the preschool period can be explained by differential exposure to environmental factors and/or differences in emotional, behavioral, or social functioning. Children from the EDEN mother-child cohort were assessed for language, gross motor, and fine motor skills at 2, 3, and 5-6 years of age using parental questionnaires and neuropsychological tests. Structural equation models examining the associations between sex and language, gross motor, and fine motor skills at 2, 3, and 5-6 years were performed while adjusting for a broad range of pre- and postnatal environmental factors as well as emotional, behavioral and socialization difficulties. Girls (n = 492) showed better fine motor skills than boys (n = 563) at 2 years (Cohen's d = 0.67 in the fully adjusted models), at 3 years (d = 0.72), and to a lesser extent at 5-6 years (d = 0.29). Girls also showed better language skills at 2 years (d = 0.36) and 3 years (d = 0.37) but not at 5-6 years (d = 0.04). We found no significant differences between girls and boys in gross motor skills at 2, 3, or 5-6 years. Similar results were found in the models unadjusted and adjusted for pre- and postnatal environmental factors as well as emotional, behavioral, and socialization difficulties. Our findings are consistent with the idea that sex differences in fine motor and language skills at 2 and 3 years of age are not explained by differential exposure to environmental factors or by sex differences in emotional, behavioral, or social functioning. PMID- 30292568 TI - A systematic assessment of socioeconomic status and executive functioning in early childhood. AB - Lower socioeconomic status (SES) consistently relates to poorer executive function (EF). This study used a systematic and nuanced approach to understand how SES relates to children's EF at a process level. We assessed children aged 4.5-5.5 years. This is a key developmental period because EF is no longer a unitary construct but rather EF components statistically load on separate factors and index distinct aspects of EF. Children completed a working memory task that involved a cognitive load component and a go/no-go task to assess inhibitory control and vigilance. Accuracy and reaction time were assessed, and each task involved four blocks to assess performance over time. Lower SES related to lower accuracy for working memory, inhibitory control, and vigilance as well as slower reaction time for working memory. SES did not relate to go/no-go reaction time. For working memory, lower SES related to poorer accuracy on lower cognitive load trials, but there were no SES differences on higher cognitive load trials. SES did not relate to maintenance of performance over time. Results suggest that for this age group the majority of domains showed SES differences. However, there were no SES differences in performance for remembering two items and maintaining performance. Thus, although overall lower SES related to poorer EF performance, there were no SES effects for skills that are still emerging for all children, namely, maintaining task performance across time and remembering two items at once. Results highlight the importance of assessing EF as a multidimensional construct and may help to identify targets for intervention. PMID- 30292569 TI - Cheating behavior in children: Integrating gaze allocation and social awareness. AB - Children's cheating and factors supporting honesty are not well understood. The current work explored variables involved in children's cheating through eye tracking and an implicit manipulation in which extrinsic awareness of the effects of one's behaviors on others was primed. Participants played a computer game with the option for a monetary gain in which they could earn more if they selectively erred in response to more profitable stimuli. Results show that children cheat by making selective effort toward more profitable errors; however, extrinsic awareness inhibits these cheating behaviors. Importantly, gaze toward children's earnings mediates this relationship, suggesting that extrinsic awareness mitigates an impulsive looking pattern, which in turn results in less cheating. Findings suggest that an implicit manipulation, highlighting the potential implications of one's actions for others, seems to effectively suppress cheating among children. Furthermore, attention toward earnings offers a cognitive process that acts to mediate the effect of this manipulation on cheating. Taken together, this framework suggests psychoneurocognitive and social processes that influence cheating in children, offering a direction for future implicit intervention techniques to support honest performance. PMID- 30292570 TI - A Novel Morphological Analysis of DXA-DICOM Images by Artificial Neural Networks for Estimating Bone Mineral Density in Health and Disease. AB - One of the best methods for diagnosing bone disease in humans is site-specific and total bone mineral density (BMD) measurements by Dual-energy X-ray Absorptiometry (DXA) machines. The basic disadvantage of this technology is inconsistent BMD measurements among different DXA machines from different manufacturers due to different image analysis algorithms. The objective of the present study was to apply artificial neural networks (ANNs) to estimate total BMD for diagnosing a population of Egyptians with and without pathology, using extracted features from DXA-DICOM images based on the Histogram and Binary algorithms as compared to reference BMD measurements by DXA machine. The sample size comprised 3000 male and female participants with an age range 22-49years, who were referred to us for diagnosis and/or treatment and for DXA total body scans in the period from January 2016 till December 2017. We constructed an entry computer data-logging visible unit, where we applied morphological operations to get a specific bone image, and used their extracted feature vectors as inputs to ANNs with cascade training, gathering, and testing for DXA-DICOM image processing. The multilayer feed-forward ANN set up its initial weights, carried out training and initiated the recall mode, and finally observed its decision and interaction based on estimated BMD. The ANN construction was carried out using a 3-layer architecture, with one hidden layer of 85 neurons. The input layer has neuron numbers equal to 256 for the Histogram and 77,365 for Binary algorithms, respectively. Total BMD estimation performance based on the Binary algorithm was capable of identifying all DXA-DICOM images with an accuracy of 100% for the training, cross-validation, and testing of the ANN phases. We believe this strategy will represent the means for standardizing bone measurements of all DXA machines, regardless of the manufacturer. PMID- 30292571 TI - Identification and expression of prostaglandin E synthase (PGES) gene in the central nervous system and ovary during ovarian maturation of the female mud crab, Scylla olivacea. AB - Prostaglandins have important physiological roles in marine invertebrates, including larval development and reproduction. The prostaglandin E concentration fluctuates during the ovarian development of crustaceans. The biosynthetic pathway of prostaglandin, however, has not been well studied in portunid crabs, including in the mud crab, Scylla olivacea. In this study, the aim was to investigate the presence of prostaglandin E synthase (PGES), enzyme that catalyzes the terminal conversion in the prostaglandin E2 (PGE2) biosynthesis, and its gene expression in the central nervous system (CNS) and ovary during ovarian maturation of S. olivacea. cDNA sequence encoding PGES was cloned from the S. olivacea ovary. The PGES transcript of S. olivacea (Scyol-PGES) consists of 1258 nucleotides, which encodes for 420 amino acid PGES protein precursor. Investigation of gene expression by RT-PCR indicated that Scyol-PGES was detected in all organs studied. Based on in situ hybridization, Scyol-PGES was detected in the I to III stages for oocyte development of Stage 3 of ovarian development, and in the CNS, including the various neuronal clusters of the brain. In the ventral nerve cord, the Scyol-PGES gene was expressed in the neurons within the subesophageal, thoracic and abdominal ganglia. The Scyol-PGES gene expression as indicated by relative abundance of mRNA in the Stage 4 of ovarian development was greater than that at Stages 1 to 3 of ovarian development. This is the first report on PGES in the mud crab, S. olivacea, and its gene expression suggested the involvement of PGES in the ovarian development of this species. PMID- 30292572 TI - In vitro developmental competence of horse embryos derived from oocytes with a different corona radiata cumulus-oocyte morphology. AB - The increase in demand for in vitro produced horse embryos is fostering the development of commercial laboratories for this purpose. Nevertheless, blastocyst production after intracytoplasmic sperm injection (ICSI) is still not as great as desired in most of these laboratories. In relation to horse oocyte classification, both expanded and compact cumulus-oocyte-complexes (COCs) are used for in vitro embryo production. The aim of this study was to compare in vitro embryo developmental capacity of COCs from horses including those with only the corona radiata, frequently collected after aspiration procedures. Horse oocytes were collected by follicular aspiration of abattoir-derived ovaries. After classification as expanded, compact or corona radiata COCs, these were in vitro matured, fertilized by ICSI and in vitro cultured for 7.5 days. Maturation rate, cleavage rate and morula/blastocyst rates were recorded. No significant differences (P > 0.05) were detected among groups in maturation rate. Cleavage rate was less (P < 0.05) for embryos derived from oocytes with a corona radiata as compared to compact-derived embryos, but embryo development after 7.5 days of culture was similar among groups (P > 0.05). In conclusion, even if embryos derived from oocytes with corona radiata had a lesser cleavage rate after ICSI, the developmental capacity was similar to embryos derived from oocytes with a compact and expanded cumulus morphology, indicating these can be an useful source of embryos in horses.

AB - INTRODUCTION: The U.K.'s current National Institute for Health and Care Excellence and the American Psychiatric Association's depression guidelines state that withdrawal reactions from antidepressants are 'self-limiting' (i.e. typically resolving between 1 and 2weeks). This systematic review assesses that claim. METHODS: A systematic literature review was undertaken to ascertain the incidence, severity and duration of antidepressant withdrawal reactions. We identified 24 relevant studies, with diverse methodologies and sample sizes. RESULTS: Withdrawal incidence rates from 14 studies ranged from 27% to 86% with a weighted average of 56%. Four large studies of severity produced a weighted average of 46% of those experiencing antidepressant withdrawal effects endorsing the most extreme severity rating on offer. Seven of the ten very diverse studies providing data on duration contradict the UK and USA withdrawal Guidelines in that they found that a significant proportion of people who experience withdrawal do so for more than two weeks, and that it is not uncommon for people to experience withdrawal for several months. The findings of the only four studies calculating mean duration were, for quite heterogeneous populations, 5days, 10days, 43days and 79weeks. CONCLUSIONS: We recommend that U.K. and U.S.A. guidelines on antidepressant withdrawal be urgently updated as they are clearly at variance with the evidence on the incidence, severity and duration of antidepressant withdrawal, and are probably leading to the widespread misdiagnosing of withdrawal, the consequent lengthening of antidepressant use, much unnecessary antidepressant prescribing and higher rates of antidepressant prescriptions overall. We also recommend that prescribers fully inform patients about the possibility of withdrawal effects. PMID- 30292575 TI - The consequences of overcoming the human skin barrier by siloxanes (silicones) Part 1. Penetration and permeation depth study of cyclic methyl siloxanes. AB - Dynamic production of cyclic siloxanes: octamethylcyclotetrasiloxane D4, decamethylcyclopentasiloxane D5 and dodecamethylcyclohexasiloxane D6 increases their concentrations in environment. It is considered that both environmental pollution and the usage of personal care products and cosmetics containing cyclic siloxanes can be the main source of the human exposure by transdermal route. The aim of the study was to verify the possibility to overcome the skin barrier by cyclic siloxanes (ATR-FTIR and GC-FID), evaluation of diffusion pathway to stratum corneum SC (Fluorescence microscopy), and determination of depth of permeation to deeper skin layers: epidermis and dermis (ATR-FTIR) and also of potential interaction with SC lipids and proteins (Fluorescence microscopy, ATR FTIR) and the cytotoxicity studies against HaCaT cells (MTT test). The results show that D4, D5 and D5 can penetrate to SC and permeate into the deeper layers of the skin: epidermis and dermis. The quantitative analysis (GC-FID) showed that total cumulative doses for D4, D5 and D6 were: 42.50; 95.37 and 77.19 MUg/cm2/24 h, respectively. The microscopic analysis proved, transepidermal route through the lipid matrix as well as through the canyons (intercluster spaces) were a diffusion pathway to the SC as well as disruption of human SC lipid structure by: D4 (the most), D5 and D6 (the least). The cytotoxicity studies demonstrated that the tested range of concentrations of D5 and D6 (up to 300 mM, 111 300 mg and 133 500 mg respectively) did not impaired the HaCaT growth, while D4 had IC50 value of 40 098 mM +/- 7.94 (10 906 +/- 872,5 mg).

AB - This study explores the association between social support and chronic disease self-management among older adults of Mexican heritage who live in the U.S. and Mexico. We hypothesize that social support increases the ability to manage hypertension and Type 2 (T2) diabetes, regardless of place of residence. We also investigate if differences in country of residence and health system factors influence the ability to manage chronic conditions. Older adults 65 years or older from Los Angeles (LA) and Mexico City (CDMX), with diagnosed hypertension or T2 diabetes (self-reported), attending government agencies, participated in the study. The statistical analyses investigate differences between older adults in LA and CDMX; identify the association between social support and chronic disease self-management; and examine the role of T2 diabetes treatment, testing and complications on self-management. Our study findings show that social support was a statistically significant predictor of improved T2 diabetes self-management (37%-51%, p < 0.05). The association between social support and hypertension self management was only significant (90% confidence level) for adherence to weight management and increased alcohol consumption. Our study did not identify statistically significant differences in social support between LA and CDMX. However, almost 40% of sampled older adults were at risk of social isolation, signaling a vulnerable population that needs to be targeted by health and social systems in the U.S. and Mexico. Our study also shows that social support is a strong predictor of improved T2 diabetes management in the U.S. and Mexico. While older adults in the U.S. and Mexico reported similar access to care and health insurance coverage, higher adherence to low salt diets in LA and reduced coverage of glucose testing in CDMX could signal areas of opportunity for policymakers. Health care providers in both countries need to identify ways of improving adherence to physical activity and weight management. PMID- 30292578 TI - Closed-loop insulin delivery in suboptimally controlled type 1 diabetes: a multicentre, 12-week randomised trial. AB - BACKGROUND: The achievement of glycaemic control remains challenging for patients with type 1 diabetes. We assessed the effectiveness of day-and-night hybrid closed-loop insulin delivery compared with sensor-augmented pump therapy in people with suboptimally controlled type 1 diabetes aged 6 years and older. METHODS: In this open-label, multicentre, multinational, single-period, parallel randomised controlled trial, participants were recruited from diabetes outpatient clinics at four hospitals in the UK and two centres in the USA. We randomly assigned participants with type 1 diabetes aged 6 years and older treated with insulin pump and with suboptimal glycaemic control (glycated haemoglobin [HbA1c] 7.5-10.0%) to receive either hybrid closed-loop therapy or sensor-augmented pump therapy over 12 weeks of free living. Training on study insulin pump and continuous glucose monitoring took place over a 4-week run-in period. Eligible subjects were randomly assigned using central randomisation software. Allocation to the two study groups was unblinded, and randomisation was stratified within centre by low (<8.5%) or high (>=8.5%) HbA1c. The primary endpoint was the proportion of time that glucose concentration was within the target range of 3.9 10.0 mmol/L at 12 weeks post randomisation. Analyses of primary outcome and safety measures were done in all randomised patients. The trial is registered with ClinicalTrials.gov, number NCT02523131, and is closed to accrual. FINDINGS: From May 12, 2016, to Nov 17, 2017, 114 individuals were screened, and 86 eligible patients were randomly assigned to receive hybrid closed-loop therapy (n=46) or sensor-augmented pump therapy (n=40; control group). The proportion of time that glucose concentration was within the target range was significantly higher in the closed-loop group (65%, SD 8) compared with the control group (54%, SD 9; mean difference in change 10.8 percentage points, 95% CI 8.2 to 13.5; p<0.0001). In the closed-loop group, HbA1c was reduced from a screening value of 8.3% (SD 0.6) to 8.0% (SD 0.6) after the 4-week run-in, and to 7.4% (SD 0.6) after the 12-week intervention period. In the control group, the HbA1c values were 8.2% (SD 0.5) at screening, 7.8% (SD 0.6) after run-in, and 7.7% (SD 0.5) after intervention; reductions in HbA1c percentages were significantly greater in the closed-loop group compared with the control group (mean difference in change 0.36%, 95% CI 0.19 to 0.53; p<0.0001). The time spent with glucose concentrations below 3.9 mmol/L (mean difference in change -0.83 percentage points, -1.40 to 0.16; p=0.0013) and above 10.0 mmol/L (mean difference in change -10.3 percentage points, -13.2 to -7.5; p<0.0001) was shorter in the closed-loop group than the control group. The coefficient of variation of sensor-measured glucose was not different between interventions (mean difference in change -0.4%, 95% CI -1.4% to 0.7%; p=0.50). Similarly, total daily insulin dose was not different (mean difference in change 0.031 U/kg per day, 95% CI -0.005 to 0.067; p=0.09) and bodyweight did not differ (mean difference in change 0.68 kg, 95% CI -0.34 to 1.69; p=0.19). No severe hypoglycaemia occurred. One diabetic ketoacidosis occurred in the closed-loop group due to infusion set failure. Two participants in each study group had significant hyperglycaemia, and there were 13 other adverse events in the closed-loop group and three in the control group. INTERPRETATION: Hybrid closed-loop insulin delivery improves glucose control while reducing the risk of hypoglycaemia across a wide age range in patients with suboptimally controlled type 1 diabetes.

AB - INTRODUCTION AND AIMS: Nonalcoholic fatty liver disease has now become a worldwide health problem, and its dramatic increase is due to the prevalence of diseases such as obesity, type 2 diabetes mellitus, and metabolic syndrome. The aim of our study was to publish the current prevalence of liver steatosis in a Mexican population undergoing routine medical check-up, as well as to analyze its relation to BMI, liver function tests, and lipid profile. MATERIALS AND METHODS: An observational, retrospective, cross-sectional study was conducted on patients that underwent medical check-up within the time frame of January 2011 and December 2015 at the Hospital San Javier. Patients included in the study were those with somatometry measurements (BMI), lipid profile, liver function tests, and abdominal ultrasound with a multi-frequency convex transducer. RESULTS: We found that 65% of the patients presented with overweight or obesity and there was a 49.19% prevalence of liver steatosis in the study population. That prevalence was more frequent in men and liver steatosis was strongly linked to an increase in triglycerides, AST, and GGT and a decrease in HDL. CONCLUSIONS: Establishing the technical aspects of the study was an important aid to having better correlation with and standardization of the accepted definitions, given that ultrasound is an adequate screening technique for an open population. Our results clearly showed a direct relation between liver steatosis and alterations in BMI, triglycerides, HDL, ALT, and GGT. PMID- 30292583 TI - Dietary management and supplementation with branched-chain amino acids in cirrhosis of the liver. AB - One of the most important characteristics of malnutrition is the loss of muscle mass and the severe depletion of the protein reserve, secondarily affecting energy metabolism. That impacts nutritional status and the progression of disease related complications. Nutritional treatment is one of the main factors in the comprehensive management of those patients. Achieving adequate energy intake that provides the macronutrients and micronutrients necessary to prevent or correct malnutrition is attempted through dietary measures. ESPEN, the European Society for Clinical Nutrition and Metabolism, recommends a caloric intake of 30 40kcal/kg/day, in which carbohydrates provide 45-60% of the daily energy intake and proteins supply 1.0-1.5g/kg/day. The remaining portion of the total energy expenditure should be covered by lipids. The administration of branched-chain amino acids has been shown to be beneficial not only in counteracting malnutrition, but also as a coadjuvant treatment in specific complications, thus playing a favorable role in outcome and quality of life. Therefore, branched chain amino acids should be considered part of nutritional treatment in patients with advanced stages of cirrhosis of the liver, particularly in the presence of complications. PMID- 30292585 TI - Purinergic Signaling: A New Pharmacological Target Against Viruses? AB - Viral diseases represent a major global problem in human health, with high morbidity and mortality. Despite recent progress in antiviral treatments, several viral diseases are still not controlled and millions suffer from them every year. It has recently emerged that purinergic signaling participates in viral infection and replication. Furthermore, stimulation of purinergic receptors in infected cells also induces inflammatory and antiviral responses, thus contributing to the host antiviral defense. Here we review the multiple roles played by the purinergic signaling network in cell-virus interactions that can lead either to viral maintenance in the cells or, by contrast, to stronger antiviral responses, and discuss potential future applications of purinergic signaling modulation for the treatment of viral diseases. PMID- 30292586 TI - Pyrus pyrifolia fruit peel as sustainable source for spherical and porous network based nanocellulose synthesis via one-pot hydrolysis system. AB - In the present study, we attempted revalorization of pear (Pyrus pyrifolia L.) peel residue into high value-added nanomaterials. A green and facile one-pot isolation procedure was designed to simplify the isolation process of nanocellulose directly from pear peel residue. The one-pot approach employed in this work is interesting as the reaction involved less harmful chemicals usage and non-multiple steps. The reaction was carried out by adding hydrogen peroxide as an oxidant and chromium (III) nitrate as catalyst in the acidic medium under mild process conditions. FTIR spectroscopy proved that the pear peel derived nanocellulose was purely cellulose phases without the presence of non-cellulosic layer. XRD study indicated that the isolated nanocellulose possessed of cellulose I polymorph with high crystallinity index of 85.7%. FESEM analysis clearly revealed that the considerable size reduction during one-pot process. Remarkably, TEM analysis revealed that the isolated nanocellulose consisted of network-liked nature and spherical shaped morphologies with high aspect ratio of 24.6. TGA showed nanocellulose has lower thermal stability compared to pear peel residue. This study provided a cost-effective method and straightforward one-pot process for fabrication of nanocellulose from pear peel residue. This is the first investigation on the nanocellulose extraction from pear fruit. PMID- 30292584 TI - Prevalence of eosinophilic esophagitis: A multicenter study on a pediatric population evaluated at thirty-six Latin American gastroenterology centers. AB - INTRODUCTION AND OBJECTIVE: Eosinophilic esophagitis is a chronic, immune mediated disease described in case series and publications worldwide. Over the past twenty years, the authors of different studies have attempted to evaluate its incidence and prevalence. The objetive of the present study was to estimate the prevalence of eosinophilic esophagitis in a group of children seen at 36 pediatric gastroenterology centers in ten Latin American countries. MATERIALS AND METHODS: A multicenter, observational, and cross-sectional study was conducted that estimated the period prevalence of eosinophilic esophagitis in children seen at outpatient consultation and that underwent diagnostic upper gastrointestinal endoscopy for any indication at 36 centers in 10 Latin American countries, within a 3-month time frame. RESULTS: Between April and June 2016, 108 cases of eosinophilic esophagitis were evaluated. Likewise, an average of 29,253 outpatient consultations and 4,152 diagnostic upper gastrointestinal endoscopies were carried out at the 36 participating centers. The period prevalence of eosinophilic esophagitis in the population studied (n=29,253) was 3.69 cases*1,000 (95% CI: 3.04 to 4.44), and among the children that underwent routine upper gastrointestinal endoscopy (n=4,152), it was 26x1,000 (95% CI: 22.6 to 29.4). CONCLUSIONS: The general period prevalence of eosinophilic esophagitis in a group of children evaluated at 36 Latin American pediatric gastroenterology centers was 3.69*1,000, and in the children that underwent endoscopy, it was 26*1,000. There was important prevalence variability between the participating countries and centers. The present analysis is the first study conducted on the prevalence of pediatric eosinophilic esophagitis in Latin America.

AB - In this study, the efficacy of zero-valent iron nanostructure modified by starch for removal of nitrate was investigated. Effect of zero-valent iron/starch nanoparticle in the presence of Thiobacillus dinitrificans for removal of nitrate was simulated via material studio software. Thermodynamic principles and proper equations were used via molecular dynamic (MD) simulation. The results of software predictions were demonstrated by radial distribution function (RDF), density, potential energy and temperature graphs. According to the graphs, the simultaneous in the presence of zero-valent iron/starch nanoparticle and Thiobacillus dinitrificans increase the removal efficiency of nitrate reached 91% and in the absence of nanoparticle was 44.44%. PMID- 30292588 TI - Intramedullary nailing of forearm shaft fractures by biodegradable compared with titanium nails: Results of a prospective randomized trial in children with at least two years of follow-up. AB - There are disadvantages in Elastic Stable Intramedullary Nailing (ESIN) of forearm-shaft fractures, such as the need of implant removal. Biodegradable Intramedullary Nailing (BIN) is a new technique developed for these fractures. We hypothesized that there is no difference in rotational ROM between the patients treated by BIN vs. ESIN. A randomized, controlled clinical trial included patients, aged 5-15 years, requiring surgery for forearm-shaft fractures. Biodegradable polylactide-co-glycolide (PLGA) nails (Activa IM-NailTM, Bioretec Ltd., Finland) were used in 19 and titanium nails (TEN(r), SynthesDePuy Ltd., USA) in 16 patients. Rotational ROM of forearm after two years was the primary outcome. Elbow and wrist ROM, pain and radiographic bone healing were secondary outcomes. Forearm rotation was mean 162 degrees and 151 degrees in BIN and ESIN groups, respectively (P = 0.201). No difference between the groups was found in any other ROMs. Three cases in the ESIN vs. none in the BIN group reported pain (P = 0.113). There was no clinically significant residual angulation in radiographs. Two adolescents in the BIN group vs. none in the ESIN (P = 0.245) were excluded because of implant failure; another two with complete bone union suffered from re-injury. Therefore, satisfactory implant stability among older children needs to be studied. PMID- 30292589 TI - Lixisenatide and renal outcomes in patients with type 2 diabetes and acute coronary syndrome: an exploratory analysis of the ELIXA randomised, placebo controlled trial. AB - BACKGROUND: The results of the ELIXA trial demonstrated the cardiovascular safety of lixisenatide, a short-acting glucagon-like peptide-1 receptor agonist, in patients with type 2 diabetes and acute coronary syndrome. In this exploratory analysis of ELIXA, we investigate the effect of lixisenatide on renal outcomes. METHODS: ELIXA was a randomised, double-blind, placebo-controlled trial, done at 828 sites in 49 countries. Patients with type 2 diabetes and a recent coronary artery event were randomly assigned (1:1) to a daily subcutaneous injection of lixisenatide (10-20 MUg) or volume-matched placebo, in addition to usual care, until at least 844 patients had an adjudicated major adverse cardiovascular event included in the primary outcome. Patients, study staff, and individuals involved in analysis of trial data were masked to treatment assignment. The primary and secondary endpoints of this trial have been reported previously. Here, in an exploratory analysis of ELIXA, we investigated percentage change in urinary albumin-to-creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) according to prespecified albuminuria status at baseline (normoalbuminuria [UACR <30 mg/g]; microalbuminuria [>=30 to <=300 mg/g]; and macroalbuminuria [>300 mg/g]) using a mixed-effect model with repeated measures. Time to new-onset macroalbuminuria and doubling of serum creatinine were also assessed with Cox proportional hazards models. The ELIXA trial is registered with ClinicalTrials.gov, number NCT01147250, and is completed. FINDINGS: Of 6068 patients randomly allocated between July 9, 2010, and Aug 2, 2013, baseline UACR data were available for 5978 (99%). Median follow-up time was 108 weeks. 4441 (74%; 2191 assigned to placebo and 2250 assigned to lixisenatide) had normoalbuminuria, 1148 (19%; 596 assigned to placebo and 552 assigned to lixisenatide) had microalbuminuria, and 389 (7%; 207 assigned to placebo and 182 assigned to lixisenatide) had macroalbuminuria. After 108 weeks, the placebo adjusted least-squares mean percentage change in UACR from baseline with lixisenatide was -1.69% (95% CI -11.69 to 8.30; p=0.7398) in patients with normoalbuminuria, -21.10% (-42.25 to 0.04; p=0.0502) in patients with microalbuminuria, and -39.18% (-68.53 to -9.84; p=0.0070) in patients with macroalbuminuria. Lixisenatide was associated with a reduced risk of new-onset macroalbuminuria compared with placebo when adjusted for baseline HbA1c (hazard ratio [HR] 0.808 [95% CI 0.660 to 0.991; p=0.0404]) or baseline and on-trial HbA1c (HR 0.815 [0.665 to 0.999; p=0.0491]); point estimates were similar when adjusted for other traditional renal risk factors. At week 108, the largest eGFR decline from baseline was observed in the macroalbuminuric group, but no significant differences were observed between the two treatment groups. No significant differences in eGFR decline were identified between treatment groups in any UACR subgroup. In the trial safety population, doubling of serum creatinine occurred in 35 (1%) of 3032 patients in the placebo group and 41 (1%) of 3031 patients in the lixisenatide group (HR 1.163, 95% CI 0.741-1.825; p=0.5127). As previously reported in the ELIXA trial, the proportion of patients with renal adverse events was low (48 [1.6%] of 3032 patients in the placebo group vs 48 [1.6%] of 3031 patients in the lixisenatide group) and did not significantly differ between treatment groups. INTERPRETATION: Lixisenatide reduces progression of UACR in macroalbuminuric patients, and is associated with a lower risk of new-onset macroalbuminuria after adjustment for baseline and on trial HbA1c and other traditional renal risk factors.

PMID- 30292591 TI - Early and Delayed Meniscal Shrinkage After Fresh-Frozen Lateral Meniscal Allograft Transplantation: Magnetic Resonance Imaging Study With a Midterm Follow up. AB - PURPOSE: To evaluate whether fresh-frozen meniscal allograft shrinkage occurs only during the first year of the early remodeling period or progresses over the delayed period of midterm years and to determine whether these changes were associated with certain clinical and radiologic outcomes. METHODS: We retrospectively reviewed meniscal allograft transplantations (MATs) performed by 1 senior surgeon (S-I.B.) using fresh-frozen allograft from 2008 to 2013. The inclusion criteria were the patients who had midterm follow-up magnetic resonance imaging (MRI) scans between 3 and 6 years after isolated lateral MATs. We excluded the graft tears found on the 1-year or midterm MRI scans. MATs were indicated for the treatment persistent compartmental pain in young to middle aged, physically active patients who had well-aligned nonarthritic joint without ligament insufficiency. The meniscal width of the transplants at the midbody and posterior horn was measured on day 2 (as a reference), at 1 year (after early remodeling period), and after 3 to 6 years (delayed period) postoperatively. Joint space width changes during each interval were measured on 45 degrees flexion posteroanterior views. The Lysholm score and Tegner activity scale were used to evaluate clinical outcomes. RESULTS: Eighty-four isolated lateral MATs with the midterm MRI scans were identified. Of these, 17 graft tears were found; therefore, we analyzed 67 patients (32 male and 35 female patients) with a mean age of 30.9 years (range, 15-52 years). The mean relative meniscal width at the midbody decreased to 93.7% (95% confidence interval [CI], 91.8%-95.6%; P < .001) at 1 year postoperatively and to 88.0% (95% CI, 85.6%-90.3%; P < .001) at the midterm follow-up of 4.0 +/- 1.0 years. The posterior horn shrank less than the midbody during the same period (96.0%; 95% CI, 94.8%-97.1%) at 1 year (P < .001) and 92.5% (95% CI, 91.0%-94.1%) at the last follow-up (P < .001). Although there was no severe shrinkage (>50% of the initial size), the incidence of moderate (25%-50%) changes at the midbody increased from 1 (1.5%) at 1 year to 5 (7.5%) at the last follow-up, respectively. We could not find any significant positive correlations between the relative meniscal width and patient-reported outcomes or joint space width changes after 1 year or at the last follow-up. CONCLUSIONS: Shrinkage of fresh-frozen meniscal transplants occurred during both the early remodeling and delayed midterm periods. Although the changes were greater in the midbody than in the posterior horn, the overall changes were less than those of the previous studies using cryopreserved grafts. We could not find that the meniscal shrinkage over the midterm period were significantly associated with inferior outcomes in this series. LEVEL OF EVIDENCE: Level IV, therapeutic case series. PMID- 30292592 TI - Prognostic Factors of Arthroscopic Debridement for Central Triangular Fibrocartilage Complex Tears in Adults Younger Than 45 Years: A Retrospective Case Series Analysis. AB - PURPOSE: The purpose of this study was to analyze factors that affect the treatment outcomes of arthroscopic debridement for central triangular fibrocartilage complex (TFCC) lesions in adults <45 years of age. METHODS: A total of 71 patients (mean age, 39 years; range, 20-44 years) who had been arthroscopically diagnosed with central TFCC tears were treated with arthroscopic debridement. Demographic, clinical, and arthroscopic findings were examined and analyzed. The response to treatment, including pain numeric rating scale on an ulnar provocation test; Disability of the Arm, Shoulder, and Hand score; and satisfaction with treatment, was assessed at 12-month follow-up. RESULTS: The mean pain numeric rating scale (6.6 +/- 3.6 to 2.4 +/- 2.0, P < .01) and Disability of the Arm, Shoulder, and Hand (59.3 +/- 15.0 to 33.7 +/- 14.1, P < .01) scores exhibited significant clinical improvement at 12-month follow-up. In terms of satisfaction, 43 patients (70.5%) were satisfied (enthusiastic or satisfied) and 18 (29.5%) were dissatisfied (noncommittal or disappointed). In the satisfied group, there were 24 flap and 19 wearing tears, whereas in the dissatisfied group, there were 4 flap and 14 wearing tears (P = .02). The extent of ulnar plus variance on preoperative radiographs also differed between the 2 groups (0.5 +/- 1.2 vs 1.7 +/- 1.1, P < .01). There were no significant differences in age, gender, hand dominance, or work level between the groups. After controlling for confounding variables, the wearing type tears (odds ratio, 3.4) and greater ulnar plus variance (odds ratio, 2.0) were associated with a higher likelihood of dissatisfaction after arthroscopic TFCC debridement. CONCLUSIONS: Although clinical outcome scores showed significant improvement after arthroscopic debridement for central TFCC tears, wearing type tears and greater ulnar plus variance were associated with dissatisfaction and poorer postoperative outcomes after the procedure.

AB - PURPOSE: To evaluate the arthroscopic double-layer lasso loop repair technique for delaminated posterosuperior rotator cuff tears. METHODS: Forty-one patients underwent arthroscopic rotator cuff repair of a delaminated posterosuperior rotator cuff tear by the double-layer lasso loop technique. Their preoperative and postoperative clinical and functional scores were compared to evaluate surgical outcomes. The prerequisite for inclusion was a minimum follow-up period of 2 years. We excluded patients with a history of shoulder surgery before the double-layer lasso loop repair. RESULTS: Statistically significant improvements (P < .001) were found in the Constant score (54 vs 83) and University of California, Los Angeles functional score (6.4 vs 9.5). Pain and strength improved according to the Jobe test, bear-hug test, belly-press test, Gerber lift-off test, and external rotation test (P < .001). No significant difference in strength was noted between the operated and nonoperated sides. There was only 1 complete rerupture (3.1%), whereas 5 patients (15.6%) had partial ruptures. CONCLUSIONS: The arthroscopic double-layer lasso loop repair technique for delaminated posterosuperior rotator cuff tears is an effective procedure. Our series showed a low rerupture rate. At a mean follow-up of 44 months, postoperative recovery with resultant functional, pain, and patient satisfaction scores was good to excellent and was comparable with the nonoperated side.

PMID- 30292594 TI - Revision Anterior Cruciate Ligament Reconstruction With Hamstrings and Extra articular Tenodesis: A Mid- to Long-Term Clinical and Radiological Study. AB - PURPOSE: To present the mid- to long-term clinical and radiographic outcomes of a series of patients who underwent revision anterior cruciate ligament (ACL) reconstruction with doubled gracilis and semitendinosus (DGST) autograft and a lateral extra-articular tenodesis (LET). METHODS: Patients who underwent revision ACL reconstruction with DGST and LET by a single surgeon between January 1997 and December 2013 were included. Revision was indicated by ACL failure noted on magnetic resonance imaging, persistent clinical instability, or laxity on clinical exam. Patients were evaluated preoperatively and at latest follow-up by an independent board-certified orthopaedic surgeon. Outcomes included Lachman and pivot shift tests, validated clinical and patient reported outcomes scores, and radiographic analysis. The presence of previous meniscectomy or chondral injury was recorded intraoperatively. RESULTS: A total of 118/132 potential patients (89.4%) was available for follow-up at a mean 10.6 years (3-19 years) postoperatively. Lachman and pivot shift examinations as well as the side-to-side difference on an KT-1000 arthrometer demonstrated significant improvement at latest follow-up (P < .05) versus preoperative evaluation. Severe degenerative disease was present in 25% of patients on radiograph and correlated with worsened clinical outcomes. Previous meniscectomy was the only risk factor analyzed that correlated with worsened radiographic grade. No patients had a graft tear based on clinical and/or magnetic resonance imaging evaluation, but 9 (7.6%) failed based on a side-to-side difference of >5 mm on the KT-1000, a grade >=2+ on pivot shift, or report of continued instability. CONCLUSIONS: Revision ACL reconstruction with DGST and LET at mid- to long-term follow-up provides continued improvement in clinical and radiological outcomes from preoperative assessment. Meniscectomy was the only factor related to worsened radiological grades and clinical outcomes. LEVEL OF EVIDENCE: Level IV, case series. PMID- 30292595 TI - Predictive Factors for and Detection of Lateral Hinge Fractures Following Open Wedge High Tibial Osteotomy: Plain Radiography Versus Computed Tomography. AB - PURPOSE: To compare the accuracy of plain radiography and computed tomography (CT) in detecting lateral hinge fractures and to identify predictive factors of the lateral hinge fractures after open wedge high tibial osteotomy (HTO). METHODS: This study included patients who underwent isolated primary open wedge HTO for medial compartment degenerative arthritis from 2015 to 2016 and were evaluated by postoperative CT scans and followed for a minimum of 1 year. This study involved 48 patients (48 knees) undergoing open wedge HTO for primary medial osteoarthritis. Lateral hinge fractures were evaluated on immediate plain radiographs and CT scans according to the Takeuchi classification. Predictive factors of plain radiograph-based hinge fracture and CT-based hinge fracture were investigated. RESULTS: The detection rate of lateral hinge fracture was significantly higher on CT scans than on plain radiographs (50% vs 14.6%; P < .001). Seven knees (14.6%) showed lateral hinge fractures on postoperative plain radiographs, including 6 with type I and 1 with type III fractures; 24 (50.0%) showed lateral hinge fractures on postoperative CT scans, including 20 with type I, 2 with type II, and 2 with type III fractures. CT scans detected 14 type I, 2 type II, and 1 type III hinge fractures not detected by plain radiographs. The medial opening gap width was the only predictor of lateral hinge fracture on CT scans (adjusted odds ratio, 1.565; P =.034). CONCLUSIONS: The incidence of lateral hinge fracture of the knee after open wedge HTO was higher on CT scans than on plain radiographs. The medial opening gap width was the only predictor of lateral hinge fractures, suggesting a need for care when spreading the gap to avoid lateral hinge fractures.

PMID- 30292596 TI - Biomechanical Analysis of Single-, Double-, and Triple-Bundle Configurations for Coracoclavicular Ligament Reconstruction Using Cortical Fixation Buttons With Suture Tapes: A Cadaveric Study. AB - PURPOSE: To compare the acromioclavicular (AC) joint stability of single-bundle (SB), double-bundle with an anterolateral limb (DBa), double-bundle with a posterolateral limb (DBp), and triple-bundle (TB) coracoclavicular (CC) ligament reconstructions using cortical fixation buttons with suture tapes. METHODS: Eight cadaveric shoulders were used. AC joint translation and rotational stability were tested for intact and following 4 different CC reconstruction techniques: SB, DBa, DBp, and TB configurations using cortical fixation buttons with suture tapes. For each reconstruction and native AC joint as control, anteroposterior (AP) and superoinferior translations were quantified using 10- and 15-N translational loads and anterior and posterior rotations were measured using 0.16 and 0.32-Nm rotational torque. RESULTS: DBp reconstruction showed significantly better AP stability compared with SB and DBa reconstruction at 10 and 15 N (DBp: 4.1 +/- 0.6 mm, SB: 7.8 +/- 1.1 mm, P < .001; DBa: 6.5 +/- 0.7 mm, P = .02 at 10 N; DBp: 5.5 +/- 0.8 mm, SB: 10.1 +/- 1.0 mm, P = .003; DBa: 9.1 +/- 0.7 mm, P = .02 at 15 N). The degree of total rotation showed tendency to decrease according to increasing number of bundles; however, there were no significant differences (SB: 43.1 +/- 9.2 degrees , DBa: 37.9 +/- 7.3 degrees , DBp: 33.9 +/- 6.8 degrees , TB: 32.2 +/- 6.6 degrees , P = .37 at 0.32 Nm). CONCLUSIONS: An additional posterolateral clavicular hole for CC ligament reconstruction using cortical fixation buttons with suture tapes resulted in better AP stability compared with SB reconstruction, whereas use of additional anterolateral clavicular hole did not show any improvement compared with SB reconstruction. Reconstruction using both anterolateral and posterolateral clavicular holes did not guarantee better stability compared with SB reconstruction. There was an increasing tendency of rotational stability with number of bundle increases, although they did not reach statistical difference. CLINICAL RELEVANCE: When surgeons consider double-bundle CC ligament reconstruction using cortical fixation buttons with suture tapes, it is better to position the lateral clavicular hole posteriorly to restore AP stability.

AB - PURPOSE: To evaluate the biomechanical fixation strength and gap formation of 2 different remplissage fixation methods (double pulley knotted construct and interconnected knotless repair construct) in cadaver specimens. METHODS: Seven matched pairs of human cadaveric shoulders were used for testing (mean age, 56 +/ 10 years). A shoulder from each matched pair was randomly selected to receive a Hill-Sachs remplissage using either a knotted (No. 2 FiberWire double pulley with 3.0-mm SutureTak anchors) or knotless (coreless No. 2 FiberWire interconnected between 3.9-mm knotless CorkScrew anchors) double mattress construct. The tendon was cycled between 10 and 100 N at 1 Hz for 100 cycles, followed by a single cycle pull to failure at 33 mm/s. Cyclic displacement, load to clinical failure (5 mm), yield load, and mode of failure were recorded. RESULTS: Neither construct demonstrated clinical failure under cyclic loading. Load to clinical failure was higher for the knotless repair than that of the knotted repair (788 +/- 162 N vs 488 +/- 227 N; P = .003). The yield load was higher for the knotless repair than that of the knotted repair (1,080 +/- 298 N vs 591 +/- 265 N; P = .008). The most common failure mode for the knotted repair was knot failure or tendon tearing, whereas the failure mode for the knotless repair was by anchor pull-out or tendon tear with no failures occurring via the interconnected suture construct mechanism. CONCLUSIONS: In this biomechanical study comparing cyclic and ultimate loading for 2 double mattress remplissage repairs, the construct using interconnected, knotless sutures outperformed the knotted construct. No failure of the interconnected suture construct mechanism by slippage or breakage was observed in the knotless group. CLINICAL RELEVANCE: The use of the interconnected knotless suture technique might improve the biomechanical strength of arthroscopic remplissage repairs in treating shoulder instability. PMID- 30292598 TI - Does hip center location affect the recovery of abductor moment after total hip arthroplasty? AB - BACKGROUND: In total hip arthroplasty (THA), placing the cup in an anatomic position is not always possible in case of deformities related to developmental dysplasia of the hip (DDH). Thus far, the influence of a hip center on the abductor moment after THA has not been clearly elucidated. Therefore, we performed a retrospective study to assess (1) how abductor muscle moment recovers postoperatively in THA and (2) whether acetabular cup position affects the recovery of abductor moment. HYPOTHESIS: A high hip center affects the recovery of abductor moment of a dysplastic hip after THA. PATIENTS AND METHODS: We evaluated 100 patients, who underwent unilateral primary THA, at 12 months postoperatively. The study included 86 women and 14 men, with a mean age of 65.5+/-9.9 years (range, 40 to 86 years). Patients with secondary osteoarthritis due to DDH were included (Crowe 1: 76; Crowe 2: 15, Crowe 3:9, and Crowe 4: none). A cementless straight stem was implanted in all hips. Hip abductor moment was measured using a belt-stabilized hand-held dynamometer. The ratio of moment of the affected side to that of the contralateral side was calculated as moment ratio. The horizontal and vertical centers of rotation (H-COR and V-COR) (with respect to the inter teardrop line) and vertical shift (V-shift) (difference in V COR between the affected hip and the contralateral normal hip) were determined. RESULTS: At 6 and 12 months postoperatively, the abductor moment ratios were 95.1 and 94.7%, respectively. Significant negative correlation was observed between the postoperative abductor moment ratio and V-COR at 6 months postoperatively (r= 0.2436, p=0.0238). Significant delay in the recovery of abductor moment ratio was observed in the groups with higher hip center (V-shift>15mm) (odds ratio=12.7; 95% CI: 2.11-232.1, p=0.0034) at 6 months postoperatively, which was fully recovered at 12 months postoperatively. DISCUSSION: Superior placement of a hip center, more than 15mm above the true hip center, delayed the recovery of abductor muscle moment after THA. LEVEL OF EVIDENCE: III, retrospective comparative study. PMID- 30292599 TI - Editorial. PMID- 30292600 TI - Mindfulness for Healthcare Providers: The Role of Non-Reactivity in Reducing Stress. AB - CONTEXT: There is strong evidence in the literature that the cultivation of mindfulness through programs such as Mindfulness-Based Stress Reduction (MBSR) has a profound impact on perceived stress for healthcare providers. The mechanism of the latter association is still being studied. However, it has been hypothesized that in particular, the cultivation of non-reactivity as a mindfulness skill may be particularly associated with the salutary effect of MBSR to reduce stress in health care providers even if adjusted for the benefit on quality of life gained after MBSR. The latter may represent important mechanistic information to build customized mindfulness interventions for health care providers. OBJECTIVE: Determine whether the change in non-reactivity to inner experience after MBSR is associated with the adjusted changes in perceived stress after MBSR. DESIGN: a Cross-sectional study. SETTING: A large, Midwestern teaching hospital. PARTICIPANTS: 100 health care providers. INTERVENTION: 8-week standard MBSR course. MAIN OUTCOME MEASURES: Perceived Stress Scale-10, Linear Analog Scale Assessment to measure Quality of life, and the mindfulness domain non-reactivity to inner experience was assessed by the non-reactivity subscale of the Five Facet Mindfulness Questionnaire. All measures were administered at baseline and completion of the intervention. RESULTS: The change from baseline to completion of MBSR was significant for all variables, with moderate-to-robust effect sizes. There was a significant negative correlation between non-reactivity and perceived stress both at baseline (p < 0.0001) and when comparing changes in scores from baseline to post-intervention (p < 0.0001). Change in non-reactivity to inner experience was robustly associated with the change in perceived stress (p < 0.0001) after MBSR (97% in 5000 bootstrapped models). CONCLUSION: Non reactivity to inner experience is a key aspect of MBSR that is independently associated with a change in perceived stress in health care providers. PMID- 30292601 TI - The association between diabetes and thoracic aortic aneurysms. AB - OBJECTIVE: The negative correlation between diabetes mellitus (DM) and abdominal aortic aneurysms (AAAs) is well described. The etiologic similarities and differences between AAAs and thoracic aortic aneurysms (TAAs) have also been documented. We aimed to evaluate the relationship between DM and TAA by performing a meta-analysis of contemporary clinical studies. METHODS: A systematic search of the literature was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to investigate the relationship of DM and TAA. Data from population cohort and case control studies were extracted and computed together to determine a pooled unadjusted odds ratio (OR) with corresponding 95% confidence intervals (CIs) using random-effects meta-analysis. RESULTS: Five population cohort studies and five case-control studies involving 1,006,360 patients met eligibility requirement and were included. Unadjusted pooled analysis of all 10 studies demonstrated an inverse association of DM with TAA (OR, 0.77; 95% CI, 0.61-0.98). Primary analysis of the five cohort studies demonstrated a statistically significant negative association between DM and TAA (OR, 0.70; 95% CI, 0.59 0.84). However, primary analysis of the five case-control studies demonstrated a negative association between DM and TAA (OR, 0.86; 95% CI, 0.50-1.47) with no statistical significance. CONCLUSIONS: This meta-analysis demonstrated a statistically significant inverse association between DM and TAA, similar to that of AAA. Further research is required into the potentially protective mechanisms that DM may confer and whether there is biologic plausibility to exploit these mechanisms further to prevent aneurysm expansion and rupture. PMID- 30292602 TI - Not all lightweight lead aprons and thyroid shields are alike. AB - OBJECTIVE: With the explosion of minimally invasive surgery, the use of fluoroscopy has significantly increased. Concurrently, there has been a demand for lighter weight aprons. The industry answered this call with the development of lightweight aprons. Our goal was to see whether lighter weight garments provide reduced protection. METHODS: Dry laboratory testing was performed in a standard X-ray room, using a standard fluoroscopy table and standard acrylic blocks. A commercial-grade pressurized ion chamber survey meter (Ludlum Model 9DP; Ludlum Measurements, Inc, Sweetwater, Tex) was used to detect gamma rays and X-rays above 25 keV. Nonlead aprons from several manufacturers were tested for scatter radiation penetration above the table at a fixed distance (3 feet) and compared with two standard 0.5-mm lead aprons of different manufacturers. RESULTS: Scatter measurements were made at 60 kVp and 70 kVp for pure lead (0.5 mm), mixed, and nonlead protective garments. Scatter penetration for the nonlead blends and barium aprons was 292% and 258%, respectively, at 60 kVp compared with the pure lead apron. At the higher beam quality of 70 kVp, the scatter penetration was 214% and 233% for the blend and barium aprons, respectively, compared with the pure lead apron. Our measurements demonstrate a noticeable difference in scatter reduction between pure lead and nonlead garments. Pure barium aprons and nonlead aprons from certain companies demonstrated scatter penetration that is inconsistent with the 0.5 mm of lead equivalence as claimed on the label. In addition, there was an incidental finding of a handful of lightweight aprons with significant tears along the seams, leaving large gaps in protection. Our study also demonstrates that several companies rate their lightweight garments as 0.5 mm lead equivalent, when actually only a small area on the chest and abdomen where the garment overlapped was 0.5 mm, leaving the rest of the garment with half the protection at 0.25 mm. CONCLUSIONS: Our reliance on protective lead garments to shield us from the biologic effects of radiation exposure and the inferiority of some lightweight garments necessitate a streamlining of the testing methods and transparency in data reporting by manufacturers. PMID- 30292603 TI - Open staged repair of splenic and extensive superior mesenteric artery aneurysms. AB - A 31-year-old man with a history of multiple strokes of unknown etiology presented with multiple asymptomatic visceral artery aneurysms including a 3.3-cm bilobed splenic artery aneurysm and a 3.1-cm fusiform superior mesenteric artery aneurysm. He had no family history of aneurysms, and there was no evidence of collagen disease. He underwent open splenic artery aneurysm resection without splenectomy and had an uneventful recovery. Seven months later, he had open repair of his 14.6-cm-long fusiform superior mesenteric artery aneurysm with a 15 cm-long collagen-coated polyester interposition graft with multiple visceral branch reimplantations into the graft. The postoperative course was uneventful, and computed tomography confirmed patent graft and side branches. Two years later, the patient remained free of abdominal symptoms, although he suffered another episode of a mild stroke. PMID- 30292604 TI - Outcomes and cost of fenestrated versus standard endovascular repair of intact abdominal aortic aneurysm in the United States. AB - BACKGROUND: Fenestrated endovascular aneurysm repair (FEVAR) has expanded the indications of this minimally invasive procedure to include patients with pararenal aneurysms. The actual cost of this relatively newer technology compared with standard endovascular aneurysm repair (EVAR) has not been studied before. Thus, the aim of this study was to analyze in-hospital costs and adverse outcomes in patients undergoing FEVAR vs EVAR for intact abdominal aortic aneurysms (AAAs). METHODS: Using the Premier Healthcare Database (2012-2015), we identified all patients who underwent elective EVAR and FEVAR. Univariable (chi2 test, Student t-test, median test) and multivariable (logistic regression and generalized linear modeling) analyses were implemented to examine in-hospital cost and adverse outcomes adjusting for patients' demographics, comorbidities, and regional characteristics. RESULTS: A total of 17,689 elective endovascular AAA repairs were performed; 1641 patients underwent FEVAR (9%), and the remaining 16,048 patients underwent standard EVAR (91%). Patients undergoing FEVAR were more likely to be white (86.3% vs 84.3%; P = .03). Both groups had similar comorbidities except for cerebrovascular disease, which was higher among patients undergoing FEVAR (8.4% vs 6.7%; P = .01). The total length of hospital stay was slightly higher in patients undergoing FEVAR compared with EVAR (mean [standard deviation], 2.40 [3.39] days vs 2.23 [3.10] days; P = .03). The rates of any complication (11.3% vs 9.6%), renal injury (5.8% vs 4.3%), and neurologic injury (0.7% vs 0.4%) were significantly higher in the FEVAR group (all P < .05). No differences were seen in mortality (0.8% vs 0.5%) or cardiac (4.9% vs 4.4%), pulmonary (2.4% vs 2.2%), and bowel (1.5% vs 1.2%) complications between the two groups (all P > .05). In multivariable logistic regression analysis, FEVAR was associated with 40% increased odds of renal failure (odds ratio, 1.40; 95% confidence interval [CI], 1.11-1.76; P = .004) and 91% increased odds of neurologic injury (odds ratio, 1.91; 95% CI, 1.02-3.57; P = .04). The median total cost of the treatment was also significantly higher among patients undergoing FEVAR ($28,227 vs $26,781; P < .001). After adjustment, generalized linear modeling analysis showed that the cost of FEVAR was on average $1612 higher than the cost of EVAR (adjusted cost, $1612; 95% CI, $1123-$2101; P < .001). CONCLUSIONS: In this large cohort of elective endovascular AAA repairs, compared with standard EVAR, FEVAR is associated with significantly increased odds of renal and neurologic injury. In addition, despite adjusting for patients' demographics, comorbidities, and major complications, total cost of FEVAR was significantly higher compared with standard EVAR. This is likely driven by the additional cost of fenestrated endografts and by the increased rate of complications related to FEVAR. PMID- 30292605 TI - Long-term outcomes after pediatric peripheral revascularization secondary to trauma at an urban level I center. AB - OBJECTIVE: The purpose of this investigation was to determine our limb-related contemporary pediatric revascularization perioperative and follow-up outcomes after major blunt and penetrating trauma. METHODS: A retrospective review was performed of a prospectively maintained pediatric trauma database spanning January 2010 to December 2017 to capture all level I trauma activations that resulted in a peripheral arterial revascularization procedure. All preoperative, intraoperative, and postoperative continuous variables are reported as a mean +/- standard deviation; categorical variables are reported as a percentage of the population of interest. RESULTS: During the study period, 1399 level I trauma activations occurred at a large-volume, urban children's hospital. The vascular surgery service was consulted in 2.6% (n = 36) of these cases for suspected vascular injury based on imaging or physical examination. Our study population included only patients who received an arterial revascularization, which was performed in 23 of the 36 consultations (1.6% of total traumas; median age, 11 years). These injuries were localized to the upper extremity in 60.9% (n = 14), lower extremity in 30.4% (n = 7), and neck in 8.7% (n = 2). The mean Injury Severity Score in the revascularized cohort was 14.0 (+/-7.6). Bone fractures were associated with 39.1% of the vascular injuries (90% of blunt injuries). Restoration of in-line flow was achieved by an endovascular solution in one patient and open surgery in the remainder, consisting of arterial bypass in 59.1% and direct repair in 40.9%. Within 30 days of the operation, we observed no deaths, no infections of the arterial reconstruction, and no major amputations. One patient required perioperative reintervention by the vascular team secondary to the development of a superficial seroma without evidence of graft involvement. Mean follow-up in our cohort was 43.3 (+/-35.4) months. During this phase, no additional deaths, amputations, chronic wounds, or limb length discrepancies were observed. All vascular repairs were patent, and all but one patient reported normal function of the affected limb at the latest clinic visit. CONCLUSIONS: Traumatic peripheral vascular injury is rare in the pediatric population but is often observed secondary to a penetrating force or after long bone fracture. However, contemporary perioperative and long-term outcomes after surgical revascularization are excellent as demonstrated in this institutional case series. PMID- 30292606 TI - Contemporary outcomes of thoracofemoral bypass. AB - OBJECTIVE: Thoracofemoral bypass (TFB) is an alternative to aortofemoral bypass (AFB) or extra-anatomic bypass for severe aortoiliac occlusive disease (AIOD). TFB may be particularly useful in select patients with concurrent visceral aortic branch vessel disease, infrarenal aortic occlusions, or after failed AFB. However, there are few contemporary series describing the indications and outcomes for TFB. Therefore, the purpose of this analysis was to review our experience with TFB. METHODS: All patients undergoing TFB for occlusive disease from 2002 to 2017 were reviewed. All patients underwent left thoracoretroperitoneal exposure of the supraceliac aorta with division of the diaphragmatic crus and supraceliac cross-clamping. An end-to-side aortic anastomosis was created and each graft limb was tunneled in the retroperitoneum to the femoral bifurcation. Adjunctive visceral/infrainguinal revascularization was performed selectively based on symptoms, end-organ function, and/or preoperative imaging. The primary end points were major complications and 30-day mortality. Secondary end points included limb patency, freedom from major adverse limb events, and survival. Kaplan-Meier methodology was used to characterize the end points. RESULTS: Forty-one patients (age 61 +/- 9 years; 54% female; 7% in a hypercoaguable state) underwent TFB. The mean preoperative ankle-brachial index was 0.4 bilaterally. Indications included critical limb ischemia (56%), claudication (30%), acute limb ischemia (7%), and combined AIOD and mesenteric ischemia (7%). Seven patients (17%) had previously undergone AFB and 15 (38%) had previously undergone any prior aortic operation. Adjunctive visceral bypass occurred in 8 patients (20%; N = 14 grafts, n = 6 renal, n = 5 superior mesenteric artery, and n = 3 celiac). The postoperative duration of stay was 11 days (interquartile range [IQR], 7-16 days) and the 30-day mortality was 5% (n = 2). Major complications occurred in 34% of patients (N = 14; pulmonary, 15%; cardiac, 12%; bleeding, 7%; accidental splenectomy, 5%; renal, 5%; wound, 2%). The mean postoperative ankle-brachial index was 0.9 bilaterally. At a median follow-up of 7 months (IQR, 1-17 months), 5 patients (12%) underwent some form of reintervention (graft/limb related, n = 4 [n = 2 graft thrombosis, n = 2 graft infection], n = 1 mesenteric bypass revision). The estimated 3-year primary limb patency and freedom from major adverse limb events were 80 +/- 10%, and 70 +/- 10%, respectively. The estimated 5-year survival was 93 +/- 5% (median, 27.3; IQR, 14.5-35.2; 95% confidence interval, 17.9-32.8). CONCLUSIONS: This experience represents one of the largest and most current series of retroperitoneal TFB. We demonstrate that TFB can be performed with good outcomes for patients with severe AIOD, especially if concomitant visceral/infrainguinal reconstruction is warranted. These results support a continued role for TFB in select patients. PMID- 30292607 TI - Open versus endovascular treatment of subclavian artery atherosclerotic disease. AB - OBJECTIVE: The aim of this study was to compare open and endovascular treatment of patients with subclavian artery atherosclerotic disease (SAAD) as far as early and late outcomes are concerned. METHODS: A systematic literature review conforming to established criteria was conducted to identify eligible articles published before January 2018. The following online search engines were used: PubMed, Embase, Scopus, and Cochrane Library (search conducted between December 2017 and January 2018). Eligible studies compared early and late major outcomes between open and endovascular therapy for patients suffering from SAAD. RESULTS: Overall, seven clinical studies included 731 patients undergoing 760 procedures in total (297 endovascular and 463 open procedures). The majority of procedures (99.7%) referred to symptomatic patients, and more patients undergoing open surgery had an occlusion compared with patients undergoing endovascular repair, the majority of whom had a stenosis. Regarding early outcomes (30-day death, cardiac events, technical success, and central nervous system events), there was no difference between the two methods. Only peripheral nervous system complications were more prevalent in patients undergoing open repair (odds ratio [OR], 7.01; 95% confidence interval [CI], 2.142-22.921; P = .001). Regarding late outcomes, open repair was associated with significantly higher 1-year (OR, 4.33; 95% CI, 1.954-9.619; P = .0003), 3-year (OR, 5.67; 95% CI, 2.881-11.167; P < .0001), and 5-year (OR, 4.27; 95% CI, 1.906-9.567; P = .0004) primary patency rates compared with endovascular therapy. However, 5-year freedom from recurrent symptoms as well as 5-year overall survival showed no difference. CONCLUSIONS: Open repair and endovascular repair in patients with SAAD do not show any difference concerning the majority of early major outcomes, although more patients undergoing open repair had an occlusion. However, open surgery seems to prevail regarding long-term primary patency, although long-term survival and freedom from recurrent symptoms show no difference. PMID- 30292608 TI - Near-instant noninvasive optical imaging of tissue perfusion for vascular assessment. AB - BACKGROUND: Noninvasive vascular tests are critical for identifying patients who may benefit from surgical revascularization, but current tests have significant limitations in people with diabetes. This study aimed to evaluate the ability of spatial frequency domain imaging (SFDI), an optical imaging method capable of measuring tissue oxygen saturation (StO2) and tissue hemoglobin, to assess lower extremity blood supply. METHODS: Ankle-brachial index, toe-brachial index, pedal Doppler waveforms, and SFDI images were prospectively evaluated in 47 consecutive patients with and without diabetes in whom there was concern for peripheral artery disease (PAD). SFDI is a noncontact optical imaging technology that uses structured illumination to quantify subsurface (2-3 mm in depth) StO2 and tissue hemoglobin in the dermal microcirculation (HbT1) and macrocirculation (HbT2) over a large field of view (15 * 20 cm) within 10 seconds. RESULTS: This demonstrates the ability of SFDI to capture reliable clinical measurements of perfusion in plantar aspects of the feet. SFDI StO2 values differentiate nondiabetic patients with and without arterial disease, defined as ankle-brachial index <0.9 (P = .06), but are limited in those with diabetes (P = .43). An elevated StO2 and reduced HbT1 are observed in people with diabetes compared with nondiabetic patients (P < .05). An SFDI-derived HbT2/HbT1 index differentiates diabetics with PAD vs no PAD (P < .01) using toe-brachial index <0.7 as a cutoff for PAD in diabetes. CONCLUSIONS: SFDI is a feasible, rapid, and easy to use widefield measurement of perfusion in a clinical setting. This first-of-use study suggests that the technology has potential to evaluate lower extremity perfusion in people with and without diabetes. Further studies with increased numbers of patients and end points including wound healing will need to be designed to fully evaluate the applicability of this new technology. PMID- 30292609 TI - Impact of routine completion angiography on outcome after carotid endarterectomy. AB - OBJECTIVE: The objective of this study was to analyze the impact of completion digital subtraction angiography (cDSA) after carotid endarterectomy (CEA) on technical and early clinical results. METHODS: This retrospective study included consecutive patients undergoing CEA from January 2011 to January 2015. Routine cDSA was performed in all patients. Study end points were the incidence of pathologic findings on completion angiography necessitating intraoperative revision, type of revision, periprocedural stroke rate, mortality, morbidity, and recurrent stenosis rate during follow-up (median, 5 months; range, 0-39 months). RESULTS: There were 827 procedures performed in 770 patients (male, 72.5%; median age, 70.6 years) with extracranial internal carotid artery (ICA) stenosis (asymptomatic, 57.3%); 426 patients underwent conventional endarterectomy (cCEA) with patch angioplasty (51.6%), 393 patients (47.5%) received an eversion technique (eCEA), and 8 patients (1%) underwent other revascularization. Immediate surgical revision based on angiographic findings after CEA was performed in 6.9% (57/827) of cases. Reasons for revision of the ICA were mural thrombus in 7.0% (4/57), dissections in 7.0% (4/57), residual stenosis in 8.7% (5/57), and intimal flaps of ICA in 1.8% (1/57). In six cases, combined pathologic changes of the ICA and external carotid artery led to revision. Thirty five revisions (4.2%) were performed for isolated pathologic angiographic findings of the external carotid artery; in two cases, revision was performed for residual stenosis of the common carotid artery. There was no significant difference regarding the frequency of revision between surgical techniques (cCEA, 56.4%; eCEA, 63.6%; P = .76). However, mural thrombus as a reason for revision was more common in the cCEA group; plaque residues were more common in the eCEA group. Periprocedural (30-day) stroke rate was 0.5% (4/827); six additional patients suffered transient ischemic attack (0.7%). The mortality rate within 30 days was 0.1% (1/827); 30-day morbidity was 4.2% (35/827). The rate of recurrent stenosis (>50%) during follow-up was 0.8%. There was no significant correlation between pathologic findings on cDSA with consecutive revision and perioperative stroke rate, recurrent stenosis rate, mortality, or morbidity. CONCLUSIONS: In this study, cDSA after CEA detected findings leading to immediate intraoperative surgical revision in a relevant proportion of cases. Therefore, cDSA represents a reasonable quality control without being associated with significantly prolonged operating times. Whether cDSA reduces perioperative stroke rate, procedure related mortality, morbidity, or incidence of early recurrent stenosis cannot be proven with the current study design. PMID- 30292610 TI - Increased hospital costs are associated with low skeletal muscle mass in patients undergoing elective open aortic surgery. AB - OBJECTIVE: Low psoas muscle area is shown to be an indicator for worse postoperative outcome in patients undergoing vascular surgical. Additionally, it has been associated with longer durations of hospital stay in patients with cancer who undergo surgery and subsequently greater health care costs in Europe and the United States. We sought to evaluate this effect on hospital expenditure for patients undergoing vascular repair in a health care system with universal access. METHODS: Skeletal muscle mass was assessed on preoperative abdominal computed tomography scans of patients undergoing open aortic aneurysm repair in a retrospective fashion. The skeletal muscle index (SMI) was used to define low muscle mass. Health care costs were obtained for all patients and the relationship between a low SMI and higher costs was explored using linear regression and cross-sectional analysis. RESULTS: We included 156 patients (81.5% male) with a median age of 72 years undergoing elective surgery for infrarenal abdominal aortic aneurysm in this analysis. The median SMI for patients with low skeletal muscle mass was 53.21 cm2/kg and for patients without, 70.07 cm2/kg. Hospital duration of stay was 2 days longer in patients with low skeletal muscle mass as compared with patients with normal (14 days vs 11 days; P = .001), as was duration of intensive care stay (3 days vs 1 day; P = .01). The median overall hospital costs were ?10,460 higher for patients with a low SMI as compared with patients with a normal physical constitution (?53,739 [interquartile range, ?45,007-?62,471] vs ?43,279 [interquartile range, ?39,509-?47,049]; P = .001). After confounder adjustment, a low SMI was associated with a 14.68% cost increase in overall hospital costs, for a cost increase of ?6521. CONCLUSIONS: Low skeletal muscle mass is independently associated with higher hospital as well as intensive care costs in patients undergoing elective aortic aneurysm repair. Strategies to reduce this risk factor are warranted for these patients. PMID- 30292611 TI - Metabolic syndrome is associated with increased cardiac morbidity after infrainguinal bypass surgery irrespective of the use of cardiovascular risk modifying agents. AB - BACKGROUND: The burden of metabolic syndrome (MetS) is increasing in the United States and is pervasive among patients with peripheral arterial disease. Whereas MetS has been implicated in the development of all types of cardiovascular disease and adverse outcomes after vascular interventions, little is known about how MetS influences perioperative outcomes of lower extremity bypass surgery and whether any negative effects can be modified by use of cardiovascular risk modifying medications. METHODS: We used the National Surgical Quality Improvement Program vascular procedure-targeted database to capture patients undergoing infrainguinal bypass surgery between 2011 and 2015. We defined MetS using the modified MetS criteria: concomitant diabetes, hypertension, and body mass index >30 kg/m2. We used multivariable logistic regression analyses to examine the association between MetS and 30-day postoperative morbidity and mortality. We also examined whether preoperative aspirin, statin, and beta blockade modify the effects of MetS on 30-day postoperative outcomes. RESULTS: Of 10,053 patients who underwent infrainguinal bypass, 16% (1693) met criteria for MetS. After adjusting for covariates, MetS was significantly (P <= .05) associated with higher odds of postoperative myocardial infarction (odds ratio [OR], 1.66), infection (OR, 1.76), renal dysfunction (OR, 2.42), and length of stay (0.34 days). Within the MetS subgroup, there were no significant associations between use of preoperative cardiovascular risk-modifying agents and postoperative outcomes, with the exception of beta blockade and an increase in length of stay (0.33 days). CONCLUSIONS: Patients with MetS undergoing infrainguinal bypass surgery are at an increased risk of postoperative complications, including myocardial infarction. This elevated risk persists despite medical therapy with preoperative aspirin, statin, and beta blockade. PMID- 30292612 TI - Aortoiliac calcification correlates with 5-year survival after abdominal aortic aneurysm repair. AB - BACKGROUND: An anatomic severity grade (ASG) score to categorize and to define anatomic factors for abdominal aortic aneurysm (AAA) repair was proposed. Other studies have previously reported that aortic anatomic complexity is a marker of survival and resource utilization after repair, although it remains unclear whether individual components of the ASG score independently contribute to survival. This study analyzed and validated an aortic and iliac artery calcium scoring system that can potentially predict survival after AAA repair. METHODS: Patients who underwent infrarenal AAA repairs from July 2007 to May 2012 were analyzed using complete 5-year records. Those who died <=30 days of surgery were excluded. Calcium score (CS) was defined using the ASG scoring system for its basis by preoperative imaging <6 months before surgery. A CS for any patient was 0 to 5 points, the sum of the points assigned to aortic neck (2 points total) and iliac artery (3 points total) calcification. A receiver operating characteristic curve was used to determine a CS threshold for mortality. The 5-year survivors and deaths were compared in regard to comorbidities, pharmacology, and CS at or above the defined threshold. Each variable with a P value <.1 between the groups was then placed into a Cox proportional hazards model, with statistical significance of P < .05. RESULTS: There were 356 patients who underwent AAA repair with complete 5-year follow-up data; 26% died within 5 years of surgery. Of these, 13% had CS of 0 with 15% mortality, 28% had CS of 1 with 21% mortality, 24% had CS of 2 with 24% mortality, 23% had CS of 3 with 35% mortality, 10% had CS of 4 with 40% mortality, and 2% had CS of 5 with 17% mortality. The receiver operating characteristic curve demonstrated an appropriate threshold of CS 3. Of these patients, 65% had a CS <3, whereas 35% had a CS >=3. Patients with a CS >=3 had a lower 5-year survival probability (P = .003). Comparing 5-year survivors and deaths in a Cox proportional hazards analysis, CS >=3 was associated with a hazard ratio of 1.579 (95% confidence interval, 1.038-2.402; P = .0328). CONCLUSIONS: A CS >=3 is linked to a lower 5-year survival after AAA repair in our population. This system potentially can be another measure for risk stratification and serve as a means to predict midterm mortality in AAA repairs. Future study will be needed for further validation to predict midterm mortality and to better guide surgical decision-making. PMID- 30292613 TI - Randomized multicenter trial on percutaneous versus open access in endovascular aneurysm repair (PiERO). AB - BACKGROUND: In endovascular valve and aortic repair, vascular access through a percutaneous approach has become the competing technique to an open surgical approach. The effect on postoperative complications and surgical site infections (SSIs) has been investigated, but randomized evidence is lacking. The objective was to investigate whether percutaneous access of the common femoral artery (CFA) with a percutaneous closure device would decrease the number of SSIs compared with open surgical access of the CFA in endovascular aneurysm repair (EVAR). METHODS: Patients with an abdominal aortic aneurysm suitable for EVAR were randomized to open or percutaneous access of the main device (MD) through the CFA. Through the contralateral side, access was obtained with the other technique than the one for which the MD was randomized. The primary outcome was number of SSIs. Secondary outcomes were wound complications, visual analog scale for pain scores, and standardized wound assessment scores during follow-up. Preoperative screening culture and groin biopsy specimens were obtained from all patients. RESULTS: Both groups contained 137 groins. SSI rate was 1.5% in the open group vs 0% in the percutaneous group. For MDs only, SSI rate was 3.1% (odds ratio, 3.3; 95% confidence interval, 0.31-347; P = .34). Wound complications were comparable in both groups. Neither nasal nor groin Staphylococcus aureus carriage had a significant effect on SSIs, Southampton Wound Assessment score, or visual analog scale score. Adjusted pain score was 0.69 lower, in favor of percutaneous access. Wound assessment was better after 2 weeks (odds ratio, 3.57; 95% confidence interval, 1.02-12.44; P = .046), also in favor of percutaneous access. CONCLUSIONS: Percutaneous access of the CFA does not reduce the number of SSIs. It does, however, reduce pain and improve wound healing with less inflammation 1 day and 2 weeks after EVAR, respectively. PMID- 30292614 TI - Patients with large neck diameter have a higher risk of type IA endoleaks and aneurysm rupture after standard endovascular aneurysm repair. AB - OBJECTIVE: Standard endovascular aneurysm repair (EVAR) is the most common treatment of abdominal aortic aneurysms (AAAs). EVAR has been increasingly used in patients with hostile neck features. This study investigated the outcomes of EVAR in patients with neck diameters >=30 mm in the prospectively maintained Endurant Stent Graft Natural Selection Global Postmarket Registry (ENGAGE). METHODS: This is a retrospective study comparing patients with neck diameters >=30 mm with patients with neck diameters <30 mm. The primary end point was type IA endoleak (EL1A). Secondary end points included secondary interventions to correct EL1A, aneurysm rupture, and survival. RESULTS: This study included 1257 patients (mean age, 73.1 years; 89.4% male) observed for a median 4.0 years (interquartile range, 2.7-4.8 years). A total of 97 (7.7%) patients had infrarenal neck diameters >=30 mm and were compared with the remaining 1160 (92.3%) with neck diameters <30 mm. At baseline, there were no differences between groups regarding demographics and comorbidities other than cardiac disease, which was more frequent in the >=30-mm neck diameter group (P = .037). There were no significant differences between the groups regarding neck length, angulation, thrombus, or calcification. Mean preoperative AAA diameter was 64.6 +/- 11.3 mm in the >=30-mm neck diameter group and 60.0 +/- 11.6 mm in the <30-mm neck diameter group (P < .001). Stent graft oversizing was significantly less in the >=30-mm neck diameter group (12.2% +/- 8.9% vs 22.1% +/- 11.9%; P <. 001). Five patients (5.2%) in the >=30-mm neck diameter group and 30 (2.6%) with neck diameters <30 mm developed EL1A, yielding a 4-year freedom from EL1A of 92.4% vs 96.6%, respectively (P = .09). Oversizing was 21.8% +/- 13.0% for patients developing EL1A and 21.3% +/- 12.4% for the remaining cohort (P = .99). In adjusting for neck length, AAA diameter, and device oversizing, patients with neck diameter >=30 mm were at greater risk for development of EL1A (hazard ratio, 3.0; 95% confidence interval, 1.0-9.3; P = .05). Secondary interventions due to EL1A did not differ between groups (P = .36). AAA rupture occurred in three patients with neck diameter >=30 mm (3.1%) and in eight patients with neck diameter <30 mm (0.7%; hazard ratio, 5.1; 95% confidence interval, 1.4-19.2; P = .016); two cases were EL1A related in each group. At 4 years, overall survival was 61.6% for the >=30-mm neck diameter group and 75.2% for the <30-mm neck diameter group (P = .009), which remained significant on correcting for sex and AAA diameter (P = .016). CONCLUSIONS: In this study, patients with infrarenal neck diameter >=30 mm had a threefold increased risk of EL1A and fivefold risk of aneurysm rupture after EVAR as well as worse overall survival. This may influence the choice of AAA repair and underlines the need for regular computed tomography based imaging surveillance in this subset of patients. Furthermore, these results can serve as standards with which new, possibly improved technology, such as EndoAnchors (Medtronic, Santa Rosa, Calif), can be compared. PMID- 30292615 TI - The distance of the primary intimal tear from the left subclavian artery predicts aortic growth in uncomplicated type B aortic dissection. AB - OBJECTIVE: Controversy exists about the optimal treatment of acute uncomplicated type B aortic dissection (auTBAD). Optimal medical therapy (OMT) provides excellent short-term outcomes, but long-term results are poor. Ideally, auTBAD patients who will fail to respond to OMT in the chronic phase could be identified and undergo thoracic endovascular aortic repair. The purpose of this study was to identify radiographic predictors of auTBAD patients who will fail to respond to OMT. METHODS: A review of the Emory aortic database from 2000 to 2017 identified 320 auTBAD patients initially treated with OMT. From this cohort, 121 patients with two or more contrast-enhanced imaging scans were available for analysis. These patients were initially divided into groups based on growth of the thoracic aorta >=10 mm or intervention due to aneurysmal growth: growth (n = 72) and no growth (n = 49). TeraRecon (Foster City, Calif) imaging software was used to analyze characteristics of the primary intimal tear (PIT), false lumen, and overall aortic size. Finally, Cox proportional hazards models were constructed to estimate hazard ratios and to identify predictors of OMT failure. RESULTS: The mean age of all patients was 54 +/- 11 years, and 67% were male. Thirty-eight patients (53%) in the growth group underwent intervention. There were no differences between groups in age, hypertension, diabetes mellitus, tobacco abuse, or chronic obstructive pulmonary disease. The distance of the PIT from the left subclavian artery in patients with auTBAD was significantly shorter in the growth group (growth, 27 mm [9-66 mm]; no growth, 77 mm [26-142 mm]; P < .01). Multivariable Cox regression analysis identified the distance of the PIT from the left subclavian artery and a thoracic aortic diameter >45 mm as independent predictors of failure of OMT. Partial false lumen thrombosis was not a predictor of aortic growth. CONCLUSIONS: The distance of the PIT from the left subclavian artery is a predictor of aortic growth in auTBAD. Patients with a primary tear located in zone 3 of the proximal descending thoracic aorta should be monitored closely and may be considered for early thoracic endovascular aortic repair in the setting of auTBAD. PMID- 30292616 TI - Contrast-induced nephropathy after peripheral vascular intervention: Long-term renal outcome and risk factors for progressive renal dysfunction. AB - OBJECTIVE: Contrast-induced nephropathy (CIN) is a frequently used quality outcome marker after peripheral vascular interventions (PVIs). Whereas the factors associated with CIN development have been well documented, the long-term renal effects of CIN after PVI are unknown. This study was undertaken to investigate the long-term (1-year) renal consequences of CIN after PVI and to identify factors associated with renal function deterioration at 1-year follow up. METHODS: From 2008 to 2015, patients who had PVI at our institution (who were part of a statewide Vascular Interventions Collaborative) were queried for those who developed CIN. CIN was defined by the Collaborative as an increase in serum creatinine concentration of at least 0.5 mg/dL within 30 days after intervention. Preprocedural dialysis patients or patients without postprocedural creatinine values were excluded. Preprocedural, postprocedural, and 1-year serum creatinine values were abstracted and used to estimate glomerular filtration rate (GFR). DeltaGFR was defined as preprocedural GFR minus 1-year GFR. Univariate and multivariate analyses for DeltaGFR were performed to determine factors associated with renal deterioration at 1 year. RESULTS: From 2008 to 2015, there were 1323 PVIs performed; 881 patients met the inclusion criteria. Of these, 57 (6.5%) developed CIN; 47% were male, and 51% had baseline chronic kidney disease. CIN resolved by discharge in 30 patients (53%). Using multivariate linear regression, male sex (P = .027) and congestive heart failure (P = .048) were associated with 1-year GFR decline. Periprocedural variables related to 1-year GFR decline included percentage increase in 30-day postprocedural creatinine concentration (P = .025), whereas CIN resolution by discharge (mean, 13.1 days) was protective for renal function at 1 year (P = .02). A post hoc analysis was performed with 50 PVI patients (randomly selected) who did not develop CIN, comparing their late renal function with that of the CIN group stratified by the periprocedural 30-day variables. Patients with CIN resolution at discharge had similar 1-year renal outcomes to non-CIN patients, whereas the CIN-persistent (at discharge) patients had greater renal deterioration at 1 year compared with non-CIN patients (P = .016). CONCLUSIONS: Male sex and congestive heart failure are risk factors for further renal function decline in patients developing CIN after PVI. The magnitude and duration of increase in creatinine concentration (CIN persistence at discharge) correlated with late progressive renal dysfunction in CIN patients, suggesting that early-resolving CIN is relatively benign. PMID- 30292617 TI - Lateral femoral bypass for prosthetic arterial graft infections in the groin. AB - OBJECTIVE: Prosthetic arterial graft infections (PAGIs) in the groin pose significant challenges in terms of revascularization options and risk of limb loss as well as associated morbidities. Although obturator canal bypass (OCB) has been suggested for revascularization of the extremity in these cases, moderate success rates and technical challenges have limited widespread use. Our study analyzed lateral femoral bypass (LFB) as an alternative approach for the treatment of groin PAGIs. METHODS: This is a retrospective review of a prospectively maintained database of patients who underwent LFB for groin PAGIs at a single center from 2000 to 2017. Patients' data including demographics, comorbidities, perioperative complications, graft patency, and need for reintervention were used. Patients were observed after LFB with duplex ultrasound surveillance in an accredited noninvasive vascular laboratory every 3 months during the first year, followed by every 6 months for the second year and yearly thereafter. After isolation of the infected wound with sterile dressings, remote proximal and distal arterial exposure incisions were made. LFBs were tunneled under the inguinal ligament and lateral to the infected wound from an uninvolved inflow artery or bypass graft to an uninvolved outflow vessel. RESULTS: A total of 19 LFBs were performed in 16 patients (mean age, 69 +/- 12.6 years). Three LFBs were performed urgently for acute bleeding. Choice of conduit included 6 (31.6%) autogenous vein grafts, 10 (52.6%) cadaveric grafts, 2 (10.5%) rifampin soaked Dacron grafts, and 1 (5.3%) polytetrafluoroethylene graft. Average follow up was 33 months (range, 0-103 months). Major adverse events occurring within 30 days of the operation included one (5.3%) death and one (5.3%) graft excision for pseudoaneurysm. Primary patency and primary assisted patency at 12 and 24 months were 73% and 83%, respectively. One patient required an amputation 17 months after surgery after failure of repeated revascularization attempts. Overall limb salvage was 93.8% during this follow-up period. CONCLUSIONS: In this series, LFB for management of groin PAGIs demonstrated higher patency and limb salvage rates compared with previous reports of OCB. Diligent postoperative duplex ultrasound surveillance is critical to the achievement of limb salvage and maintenance of graft patency. These results suggest that LFB, which is technically less complex than OCB, should be considered the first choice for revascularization in select cases of PAGIs involving the groin. PMID- 30292618 TI - Serum resistin is associated with impaired endothelial function and a higher rate of adverse cardiac events in patients with peripheral artery disease. AB - OBJECTIVE: Resistin is a hormone that has been associated with metabolic syndrome and cardiovascular disease. The role of resistin in patients with peripheral artery disease (PAD) has not been fully explored. This study seeks to understand the relationship between serum resistin, vascular function, and cardiovascular outcomes in patients with PAD. METHODS: There were 106 patients with PAD who were recruited between 2011 and 2016. Patients attended a baseline visit during which a comprehensive vascular physiology assessment including medical and surgical history, radial artery tonometry, and flow mediated-vasodilation (FMD) was completed. A blood sample was drawn, and serum resistin was assayed using enzyme linked immunosorbent assay kits. Using the time of study enrollment as the time of origin, incident major adverse cardiac events (MACEs) were identified by subsequent chart review and defined as a composite end point of myocardial infarction, coronary revascularization, transient ischemic attack, stroke, or death from a cardiac cause. RESULTS: Patients had a mean age of 68 +/- 8 years, were largely white (75%), and had comorbidities commonly associated with PAD including hypertension (92%), hyperlipidemia (87%), coronary artery disease (37%), and diabetes mellitus (38%). After stratification by resistin quartile, higher resistin quartiles were significantly associated with an older age, a greater number of pack-years smoked, and a lower estimated glomerular filtration rate. Despite similar comorbidities and medication use, endothelial function, as measured by FMD, was significantly lower with increasing resistin quartile (I, 9.1% +/- 3.3%; II, 7.1% +/- 3.5%; III, 5.8% +/- 4.0%; IV, 5.6% +/- 3.5%; P = .002). In multivariable linear regression, higher resistin quartiles (III and IV) were associated with lower FMD relative to quartile I after adjusting for several patient characteristics, medications, and comorbidities (III, -2.26 [95% confidence interval (CI), -4.51 to -0.01; P = .05]; IV, -2.53 [95% CI, -4.87 to 0.20; P = .03]). During a median follow-up period of 36 months (interquartile range, 29-45 months), 21 patients experienced the primary end point. In a Cox proportional hazards model adjusted for smoking status, coronary artery disease, and age, each 1 ng/mL increase in resistin was associated with a 10% increased risk of MACEs (hazard ratio, 1.10; 95% CI, 1.00-1.20; P = .04). CONCLUSIONS: In patients with PAD, higher levels of resistin were associated with impaired endothelial function and an increased rate of MACEs. These results suggest that resistin may be a marker or effector of impaired vascular physiology and adverse cardiac outcomes in patients with PAD. Further research is needed to determine the potential mechanisms by which resistin may impair endothelial function and increase MACEs in this population. PMID- 30292619 TI - Gender-related outcomes after open repair of descending thoracic and thoracoabdominal aortic aneurysms. AB - OBJECTIVE: Female sex has been associated with greater morbidity and mortality for a variety of major cardiovascular procedures. We sought to determine the influence of female sex on early and late outcomes after open descending thoracic aortic aneurysm (DTA) and thoracoabdominal aortic aneurysm (TAAA) repair. METHODS: We searched our aortic surgery database to identify patients having open DTA or TAAA repair. Logistic regression and Cox regression analyses were used to assess the effect of sex on perioperative and long-term outcomes. RESULTS: From 1997 until 2017, there were 783 patients who underwent DTA or TAAA repair. There were 462 male patients and 321 female patients. Female patients were significantly older (67.6 +/- 13.9 years vs 62.6 +/- 14.7 years; P < .001), had more chronic pulmonary disease (47.0% vs 35.7%; P = .001) and forced expiratory volume in 1 second <50% (28.3% vs 18.2%; P < .001), and were more likely to have degenerative aneurysms (61.7% vs 41.6%; P < .001). Operative mortality was not different between women and men (5.6% vs 6.2%; P = .536). However, women were more likely to require a tracheostomy after surgery (10.6% vs 5.0%; P = .003) despite a reduced incidence of left recurrent nerve palsy (3.4% vs 7.8%; P = .012). Logistic regression found female sex to be an independent risk factor for a composite of major adverse events (odds ratio, 2.68; confidence interval, 1.41 5.11) and need for tracheostomy (odds ratio, 3.73; confidence interval, 1.53 9.10). Women also had significantly lower 5-year survival. CONCLUSIONS: Women undergoing open DTA or TAAA repair are not at greater risk for operative mortality than their male counterparts are. Reduced preoperative pulmonary function may contribute to an increased risk for respiratory failure in the perioperative period. PMID- 30292620 TI - Toxicogenomic responses to zearalenone in Caenorhabditis elegans reveal possible molecular mechanisms of reproductive toxicity. AB - In this study, the possible molecular mechanisms of zearalenone (ZEA)-induced reproductive and developmental toxic effects in Caenorhabditis elegans (C. elegans) were investigated. Differential gene expression profiles were identified, and 171, 245, and 3149 genes were down- or up-regulated (>2.0 fold) in 10, 20, and 40 MUg/ml ZEA treated groups, respectively, as compared to untreated controls. Pathway specific mapping showed that the major differentially expressed genes were collagen synthetic pathways regulating genes, col-121 and dpy-17. Real-time PCR reconfirmation of key genes, related to cuticle collagen synthetic pathway, found dramatic changes in the expression of the genes dpy-31, sqt-3, col-121, and dpy-17 following exposure to ZEA (40 MUg/ml), which indicated the significance of these genes in ZEA-induced toxicity. Cuticle collagen plays many key roles in the development and reproduction of C. elegans. The hypersensitive responses in transgenic and mutant worms also confirmed the roles of these genes in lethality and reproductive response to ZEA exposure, which indicates that ZEA blocked the normal collagen processing and cuticle formation. Taken together, our results demonstrate that disruption of the collagen biosynthetic pathway might be a key mechanism in ZEA-induced reproductive and developmental toxic effects in C. elegans.

PMID- 30292622 TI - Hypocholesterolaemic and antioxidant properties of Olea europaea L. leaves from Chlef province, Algeria using in vitro, in vivo and in silico approaches. AB - Aqueous and ethanol extracts prepared from leaves of Olea europaea L. were evaluated for in vitro antioxidant and in vivo hypocholesterolemic effect. The result of administration of O. europaea leaf extracts on serum total cholesterol, triglyceride, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL) in hypercholesterolaemic mice was evaluated. In addition, rutin and luteolin, reported to occur naturally in O. europaea leaves, were docked against HMG-CoA reductase, the rate-limiting enzyme in cholesterol metabolism. Mice treated with both extracts showed reduced total cholesterol (246.6 and 163.4 mg/dl, for mice groups treated with respective extracts) and LDL (150.16 and 81.28 mg/dl, for mice groups treated with respective extracts) levels as compared to the hypercholesterolaemic group (total cholesterol 253.00 mg/dl and LDL 160.00 mg/dl). Mice treated with aqueous extract (200 mg/kg body weight) showed significantly reduced triglyceride and VLDL levels as compared to the group treated with atorvastatine. HDL level of mice administered with O. europaea aqueous extract was comparable to the atorvastatine treated group. The ethanol extract of O. europeae leaves was a potent antioxidant (IC50 69.15 mg/ml, % inhibition 54.98, 82.63 mg ascorbic acid equivalent/g extract, 7.53 mol of Fe2+/g extract, and % inhibition 49.71, for the DPPH, beta carotene bleaching, total antioxidant capacity, FRAP, and ferric thiocyanate assays, respectively). Docking studies revealed that rutin showed higher binding affinity with HMG-CoA reductase as compared to luteolin. Data gathered from this study support the development of a prophylactic biomedicine from O. europaea leaves for the management of hypercholesterolemia and atherosclerosis.

PMID- 30292624 TI - Radical Mastectomy Increases Psychological Distress in Young Breast Cancer Patients: Results of A Cross-sectional Study. AB - INTRODUCTION: The present study aimed to detect the factors associated with psychological distress (PD) in young Moroccan patients with breast cancer, with a special focus on the type of surgical procedure. PATIENTS AND METHODS: We collected social, demographic, and clinical data from female patients, aged < 45 years, with localized stage breast cancer who had undergone either radical mastectomy or conservative surgery and for whom adjuvant chemotherapy was indicated. We used the Hospital Anxiety and Depression Scale (HADS) to assess the psychological status. The relationship between the variables and PD was analyzed using simple and multiple logistic regression analyses. RESULTS: A total of 122 women were enrolled, of whom 41 (33.6%) had a HADS global score >= 15. The HAD anxiety and depression subscores were >= 11 for 10 (8.2%) and 8 (6.6%) patients, respectively. On multivariate analysis, adjusted for marital status and receipt of analgesic and/or anxiolytic treatment, we found that radical mastectomy (odds ratio [OR], 5.747; 95% confidence interval [CI], 1.342-24.608), living in a difficult emotional (OR, 7.366; 95% CI, 1.727-31.41) and/or financial (OR, 16.521; 95% CI, 3.574-76.36) situation, and a lack of social and/or family support (OR, 19.617; 95% CI, 3.549-108.43) were independent factors associated with PD. CONCLUSION: Breast-conserving surgery should be performed whenever possible for young women to avoid the psychological repercussions of radical procedures. PMID- 30292625 TI - Real-World Experience of Palbociclib-Induced Adverse Events and Compliance With Complete Blood Count Monitoring in Women With Hormone Receptor-Positive/HER2 Negative Metastatic Breast Cancer. AB - BACKGROUND: The cyclin-dependent kinase 4/6 inhibitor palbociclib has emerged as a novel therapeutic agent in metastatic breast cancer. Neutropenia is commonly observed, and thus stringent treatment guidelines regarding complete blood count (CBC) monitoring have been developed. The aim of this study was to provide a real world experience of the toxicities associated with palbociclib therapy and to evaluate compliance with CBC monitoring. PATIENTS AND METHODS: We performed a retrospective single-center audit of hormone receptor-positive metastatic breast cancer patients treated with palbociclib over a 6-month period in an Irish tertiary referral hospital. RESULTS: A total of 64 patients were included in the analysis. Palbociclib was most commonly used in combination with letrozole (n = 40). A total of 28 patients (44%; 95% confidence interval, 31.2-56.2) had treatment deferrals due to neutropenia, with a median time to first deferral of 4 weeks. Fifteen patients (23%; 95% confidence interval, 15.4-37.7) required dose adjustments; however, there was no association with an increased risk of progressive disease (P = .56). Only 3 patients discontinued treatment as a result of poor tolerance. Adverse events were as expected; however, 7 venous thromboembolic events were reported. CONCLUSION: Compliance was good with existing CBC monitoring guidelines. We observed an 11% incidence of venous thromboembolic events, a significant increase from 2% reported in the PALOMA-3 trial. Further studies are recommended to determine if prophylactic anticoagulation may benefit these patients. PMID- 30292626 TI - Hydropic leiomyoma: a distinct variant of leiomyoma closely related to HMGA2 overexpression. AB - Hydropic leiomyoma (HLM) is a variant of uterine leiomyoma with characteristic features of zonal distributions of edema, increased vascularity, and tumor cells arranged in nodules or cords. Diagnostic difficulty and patient management are further complicated by a lack of studies and unknown cause of the disease. To study this tumor's nature, 24 HLM cases were selected for analysis of cyto histologic features, immunohistochemical profile (HMGA2, FH, CD34, pAKT, p16, ER, SMA and Ki-67), and molecular alterations of HMGA2 by fluorescence in-situ hybridization (FISH) and MED12 mutations. HLM showed large tumor size (average 14.4cm) and unique histology, characterized by edematous areas of tumor cells with mostly round-oval nuclei, arranged in cords and/or with perinodular growth around vessels, and increased thick-walled vessels (average 17 vessels/10x medium power field). Immunohistochemistry revealed that 76% (18/24) of HLM had HMGA2 overexpression, 32% (6/19) of which harbored HMGA2 rearrangement detected by FISH. Thick-walled vessels in HLM were composed of mostly HMGA2 positive tumor cells; and HLM with HMGA2 overexpression also showed CD34 positive tumor vessel supporting pericytes. In contrast to usual type leiomyoma with a high frequency of MED12 mutations, no MED12 mutations were found in any HLM. HLM showed increased pAKT activity, indicating a strong contribution of AKT pathway signaling in HLM promoting tumor growth. Our findings suggest that HLM is a distinct variant of uterine smooth muscle tumor likely driven by HMGA2 overexpression. PMID- 30292627 TI - Is immunohistochemical staining for beta-catenin the definitive pathological diagnostic tool for desmoid-type fibromatosis?: a multi-institutional study. AB - Immunohistochemical staining with anti-beta-catenin antibody has been applied as a diagnostic tool for desmoid-type fibromatoses (DF). In recent years, specific gene mutation (CTNNB1) analysis has also been reported to be useful for diagnosis of DF, however the association between CTNNB1 mutation status and immunohistochemical staining pattern of beta-catenin is rarely reported. The purpose of this study is to clarify the relationship of the staining pattern of beta-catenin with the CTNNB1 mutation status and various clinical variables, and investigate the significance of immunohistochemical staining of beta-catenin in cases diagnosed with DF. Between 1997 and 2017, 104 cases diagnosed with DF from 6 institutions in Japan were enrolled in this study: Nagoya University; National Cancer Center Hospital; Niigata University; Okayama University; Kyushu University, and Cancer Institute Hospital. For all cases, immunohistochemical staining of beta-catenin and gene mutation analysis of CTNNB1 were performed. Of 104 cases, 87 (84%) showed nuclear staining of beta-catenin, and 95 (91%) positive staining in cytoplasm. The proportion of cases showing strong nuclear staining of beta-catenin was significantly higher in the cases with S45F than in those with T41A or wild type (WT). The proportion of cases stained strongly in the cytoplasm rather than in the nucleus was significantly higher in the group of T41A than that of S45F or WT. Among 17 cases in which nuclear immunostaining were absent, CTNNB1 mutation was observed in 5 cases (29.4%). There were unignorable cases of DF with negative beta-catenin immunostaining despite a definitive clinical and pathological diagnosis of DF and/or positive CTNNB1 mutation. PMID- 30292628 TI - Development of a Prediction Tool for Exclusive Locoregional Recurrence After Radical Cystectomy in Patients With Muscle-Invasive Bladder Cancer. AB - BACKGROUND: Limited information is available about the pattern of relapse after perioperative chemotherapy with radical cystectomy (RC) vs. RC alone in muscle invasive bladder cancer. PATIENTS AND METHODS: Data from 1082 patients of the Retrospective International Study of Invasive/Advanced Cancer of the Urothelium database, treated from February 1990 to December 2013 at 27 centers in the United States, Europe, Israel, and Canada, were collected. Locoregional relapse was defined as any pelvic lymph node or soft tissue-only recurrences. Cumulative incidence methods were used to estimate time to locoregional relapse (TTRL). Cox regression analyses were performed and a nomogram for 12-month locoregional relapse-free survival (RFS) was developed. The nomogram was applied to an external data set (n = 1021). RESULTS: A total of 517 patients (47.8%) developed a relapse: 177 (16.4%) exclusive locoregional relapse. In multivariable analyses, perioperative chemotherapy was associated with longer TTRL (P < .001). Other factors were nonurothelial histology (P = .013), pT-stage (P < .001), and surgical margins (P < .001). The concordance index of the model was 0.681 (95% bootstrapped confidence interval, 0.666-0.716). Risk group categories were obtained according to nomogram tertiles. Despite, overall, observed locoregional RFS in the validation cohort exceeding predicted results, for high-risk patients (80 points or less, lowest nomogram tertile) observed 12-month RFS was similar between development and validation cohorts (60.1% and 66.6%). The study is limited by its retrospective nature. CONCLUSION: In the largest study, to our knowledge, that analyzed locoregional recurrences after RC, we propose a risk prediction tool for exclusive locoregional failures that might be suitable for clinical studies. Patients best suited for adjuvant radiotherapy might be those within the lowest nomogram tertile. Prospective trials are needed to validate findings. PMID- 30292629 TI - Establishment of a protein biochip to detect serum IgG antibodies against IL-2 and soluble CD25 in hemophagocytic lymphohistiocytosis. AB - BACKGROUND: Interleukin-2 (IL-2) and soluble CD25 (sCD25) are among the most important cytokines and diagnostic biomarkers in hemophagocytic lymphohistiocytosis (HLH). Detecting serum level of IL-2 and sCD25 is valuable for making clinical diagnosis and treatment decision in HLH. METHODS: Since tests showing serum IgG antibody against IL-2 or sCD25 have never been carried out, a new protein biochip, which was modified with cysteine and activated sophorolipid (Cys-SL), was developed. RESULTS: Limits of detection on the biochip were 78 pg/ml for IL-2 and 39 pg/ml for sCD25, respectively. The data showed that on-chip seroimmunological responses to IL-2 and sCD25 proteins were 20.8% and 83.1% and the seroprevalence of IL-2 and sCD25 IgG antibodies were 45.5% and 57.2%, respectively. Data collection for the seroprevalence of serum antigen-antibody complex of sCD25 was 68.8%. The new biochip model shared similar sensitivity and specificity to chemiluminescent immunoassay (CLIA) in its measuring capacity of serum sCD25. CONCLUSIONS: We addressed and confirmed the involvement of serum IgG antibodies against IL-2 and sCD25 as well as Ag-Ab complex of sCD25 in HLH patients. Therefore, this biochip platform would offer a new technological substitution for clinical serological diagnosis of HLH. PMID- 30292630 TI - Targeted exome sequencing identified a novel mutation hotspot and a deletion in Chinese primary hypertrophic osteoarthropathy patients. AB - BACKGROUND: Primary hypertrophic osteoarthropathy (PHO) is a genetically and clinically heterogeneous systematic disorder caused by mutations in genes HPGD and SLCO2A1. The purpose of the present study is to provide useful information for the early and precise diagnosis of PHO and identify causative mutations in Chinese PHO children. METHODS AND RESULTS: The clinical manifestations, radiographic features of seven Chinese pediatric patients were systematically analyzed. Targeted exome sequencing identified a previously reported c.310_311delCT mutation and a novel common splicing site mutation c.324 + 5G > A in the HPGD gene. Relative quantitative real time PCR validated a novel deletion of the exon 4 in the same gene. Neither mutations nor structural variations in the gene SLCO2A1 were detected. CONCLUSIONS: In the present study, homozygous or compound heterozygous HPGD mutations were identified in seven Chinese pediatric patients, suggesting an autosomal recessive inheritance. The c.310_311delCT mutation and the splicing site mutation c.324 + 5G > A were likely to be mutational hotspots in Chinese PHO patients. For the first time, a structural variation of the HPGD gene was reported. Homozygous, compound heterozygous mutations or structural variation identified in the HPGD gene proposed that targeted exome sequencing may be a preferable method for pediatric PHO diagnosis and mutation analysis. PMID- 30292631 TI - Quality specifications and their daily application to evaluate the accuracy of reference measurements for serum concentrations of 25-hydroxyvitamin D3 and 25 hydroxyvitamin D2. AB - BACKGROUND: Reference measurement procedures (RMP) have rigorous accuracy specifications. For total 25-hydroxyvitamin D, 25(OH)D, bias <=1.7% and CV <=5% are recommended. These quality specifications are impractical for minor analytes, such as 25(OH)D2. Furthermore, documentation on RMP quality performance specifications for the individual 25(OH)D metabolites and their daily application are missing. METHODS: To assess accuracy, we used zeta-scores. Daily, 5-10 specimens (duplicate) and 3 reference materials (singleton or duplicate) were measured for 25(OH)D3 and 25(OH)D2 using JCTLM-accepted LC-MS/MS RMPs. Protocols were repeated on 3-4 occasions to generate campaign results. We used separate zeta-score acceptability criteria for daily (<=|2|) and campaign (<=|1|) evaluations. Allowable imprecision was determined experimentally. RESULTS: Across 7 campaigns, unacceptable daily zeta-scores required repeating 2 runs for 25(OH)D3 and 5 runs for 25(OH)D2. Hence, the zeta-scores of acceptable reference material results indicated high accuracy. The allowable imprecision for the RMPs was <=5% (daily) and <= 3% (campaign) for 25(OH)D3 and <= 7% (daily) and <= 4% (campaign) for 25(OH)D2, respectively. CONCLUSIONS: Using zeta-scores and experimentally derived imprecision, we developed a straightforward approach to assess the acceptability of individual 25(OH)D reference measurements, providing also much-needed practical accuracy specifications for 25(OH)D2. PMID- 30292632 TI - Is capillary zone electrophoresis a suitable method for estimating serum albumin: A comparison of four methods. AB - BACKGROUND: The capillary zone electrophoresis method of albumin measurement is frequently used for oncologic and haematologic patients but few data exist about the agreement between the albumin measurements performed by capillary zone electrophoresis and other methods. The aim of this study was to analyse the agreement between human serum albumin measurements by capillary zone electrophoresis and by the nephelometry, bromocresol purple and turbidimetry methods. METHOD: We prospectively measured 100 freshly collected non-frozen patient serum samples, by using four different methods: the capillary zone electrophoresis method performed with a CAPILLARYS 2 instrument, the bromocresol purple dye method performed with an Advia XPT analyser, the nephelometric method performed with a BN ProSpec analyser and the turbidimetric method with reagents from DiAgam and performed with the Advia XPT analyser. RESULTS: A bias towards higher values in the lower range of albumin concentrations was observed with capillary zone electrophoresis compared to immunonephelometry: correlation coefficient r2 = 0.925; slope of 0.86 (0.82-0.89, 95% confidence interval), which is significantly different from 1; and an intercept of 4.94 g/L (3.67-6.16, 95% confidence interval). Similar results were observed when comparing capillary zone electrophoresis to the bromocresol purple and immunoturbidimetry methods. The capillary electrophoresis method overestimated low albumin levels by up to 25% (5 g/L). CONCLUSION: Compared to the nephelometry, turbidimetry and bromocresol purple methods, the capillary zone electrophoresis method tends to overestimate human serum albumin concentrations for levels below 30 g/L. This discrepancy could lead to an overestimation of the nutritional status, an inappropriate scoring of the disease and a delay in nutritional treatment. PMID- 30292633 TI - Endoplasmic reticulum stress induces inverse regulations of major functions in portal myofibroblasts during liver fibrosis progression. AB - Portal myofibroblasts (PMF) form a sub-population of highly proliferative and proangiogenic liver myofibroblasts that derive from portal mesenchymal progenitors. Endoplasmic reticulum (ER) stress was previously shown to modulate fibrogenesis, notably in the liver. Our aim was to determine if ER stress occurred in PMF and affected their functions. PMF were obtained after their expansion in vivo from bile duct-ligated (BDL) rats and referred to as BDL PMF. Compared to standard PMF obtained from normal rats, BDL PMF were more myofibroblastic, as assessed by higher alpha-smooth muscle actin expression and collagen 1 production. Their proangiogenic properties were also higher, whereas their proliferative and migratory capacities were lower. CHOP expression was detected in the liver of BDL rats, at the leading edge of portal fibrosis where PMF accumulate. BDL PMF displayed ER dilatation and an overexpression of the PERK pathway downstream targets, Chop, Gadd34 and Trb3, in comparison with standard PMF. In vitro, the induction of ER stress by tunicamycin in standard PMF, caused a decrease in their proliferative and migratory activity, and an increase in their proangiogenic activity, without affecting their myofibroblastic differentiation. Conversely, the treatment of BDL PMF with the PERK inhibitor GSK2656157 reduced ER stress, which caused a decrease in their angiogenic properties, and restored their proliferative and migratory capacity. In conclusion, PMF develop ER stress as they expand with the progression of fibrosis, which further increases their proangiogenic activity, but also inhibits their proliferation and migration. This phenotypic switch may restrict PMF expansion while they support angiogenesis. PMID- 30292634 TI - IL-23 production of liver inflammatory macrophages to damaged hepatocytes promotes hepatocellular carcinoma development after chronic hepatitis B virus infection. AB - Liver inflammation after chronic hepatitis B virus (HBV) infection is essential for hepatocellular carcinoma (HCC) development. We did a nested case-control study based on QBC chronic HBV infection cohort to identify HCC-related inflammatory cytokines. Serum levels of distinct Th-cell representative cytokines at varied periods before HCC diagnosis were determined in 50 HCC cases and 150 age- and gender-matched controls who did not develop HCC in 8-10 years. The individuals with HCC outcome had statistically higher serum levels of IL-23 than controls (P < 0.01). Further analysis in HCC tissues showed that CD14+ inflammatory macrophages were the major IL-23 producers. Monocytes-derived macrophages generated more amount of IL-23 after being stimulated with cell associated HBV core antigen from damaged HBV-infected hepatocytes than the cells being stimulated with HBV-S and HBV e antigen, which are secreted from infected hepatocytes. IL-23 upregulated IL-23 receptor expressions on macrophages, enhanced macrophage-mediated angiogenesis. In HBV-transgenic (Alb1HBV) mice, administration of diethylnitrosamine induced more liver tumors than in wild-type mice. The livers of Alb1HBV mice had higher concentrations of IL-23 and vascular endothelial growth factor (VEGF) than the wild-type mice. Neutralizing IL-23 activity, diethylnitrosamine-treated Alb1HBV mice developed significantly less tumors and produced less VEGF, tumor angiogenesis was inhibited with dramatically decreased CD31+ cells within tumor mass (all P < 0.01). CONCLUSION: Persistent IL 23 generation of liver inflammatory macrophages responding to damaged hepatocytes after chronic HBV infection altered macrophage function for HCC promotion. Blocking IL-23 activity might be helpful for the intervention in chronic hepatitis B patients who had high risk to HCC. PMID- 30292636 TI - mTOR inhibitor INK128 attenuates systemic lupus erythematosus by regulating inflammation-induced CD11b+Gr1+ cells. AB - Systemic lupus erythematosus (SLE) is an autoimmune disease, characterized by systemic chronic inflammation that can affect multiple major organ systems. Although the etiology of SLE is known to involve a variety of factors such as the environment, random factors and genetic susceptibility, the exact role of CD11b+Gr1+ myeloid cells in lupus progression is not fully understood. Myeloid derived CD11b+Gr1+ cells are thought to be a heterogeneous group of immature myeloid cells with immune function. Some studies have reported that CD11b+Gr1+ cells and the activation of mTOR pathway are involved in the pathogenesis of systemic lupus erythematosus (SLE). However, it is still not clarified about the mechanism of influence of lupus microenvironment and mTOR signaling on CD11b+Gr1+ cells. In the present study, we found that the percentage of CD11b+Gr1+ cells increased prior to the abnormal changes of Th17, Treg, T and B cells during lupus development. TLR7 and IFN-alpha signaling synergized to promote CD11b+Gr1+ cell accumulation in an mTOR-dependent manner. Moreover, compared to a traditional mTOR inhibitor, INK128 inhibited more effectively the disease activity via regulating CD11b+Gr1+ cell expansion and functions. Furthermore, TLR7/IFN-alpha modified CD11b+Gr1+ cells promoted unbalance of Th17/Tregs and were inclined to differentiate into macrophages via the mTOR pathway. In conclusion, CD11b+Gr1+ cells increased in the early stages of the lupus progression and mTOR pathway was critical for CD11b+Gr1+ cells in lupus development, suggesting the changes of inflammation-induced CD11b+Gr1+ cells initate lupus development. We also provide evidence for the first time that INK128, a second generation mTOR inhibitor, has a good therapeutic action on lupus development by regulating CD11b+Gr1+ cells. PMID- 30292635 TI - Differential expression of tumor-associated genes and altered gut microbiome with decreased Akkermansia muciniphila confer a tumor-preventive microenvironment in intestinal epithelial Pten-deficient mice. AB - Phosphatase and tensin homolog (Pten) antagonizes PI3K-Akt signaling; therefore, Pten impairment causes tumorigenesis. However, the correlation between Pten deficiency and colon cancer has remained elusive due to numerous opposite observations. To study this correlation, we examined whether Pten deficiency in intestinal epithelial cells (IECs) induces tumorigenesis. With mucosal biopsies of human colon cancer and normal colon, Pten mRNA was evaluated by quantitative PCR. Using IEC-specific Pten knockout mice (PtenDeltaIEC/DeltaIEC), we examined the mitotic activity of IECs; and PtenDeltaIEC/DeltaIEC; Apcmin/+ mice were generated by combining PtenDeltaIEC/DeltaIEC with Apcmin/+ mice. Tumor-associated gene was evaluated by micro-array analysis. Fecal microbiome was analyzed through 16S rRNA gene sequencing. We found that Pten mRNA level was reduced in human colon cancer relative to normal tissues. Augmented chromatids, increased Ki-67 and PCNA expression, and enhanced Akt activation were identified in IECs of PtenDeltaIEC/DeltaIEC mice compared to Pten+/+ littermate. Combining PtenDeltaIEC/DeltaIEC with Apcmin/+ condition caused rapid and aggressive intestinal tumorigenesis. However, PtenDeltaIEC/DeltaIEC mice did not develop any tumors. While maintaining the tumor-driving potential, these data indicated that IEC-Pten deficiency alone did not induce tumorigenesis in mice. Furthermore, the expression of tumor-promoting and tumor-suppressing genes was decreased and increased, respectively, in the intestine of PtenDeltaIEC/DeltaIEC mice compared to controls. The abundance of Akkermansia muciniphila, capable of inducing chronic intestinal inflammation, was diminished in PtenDeltaIEC/DeltaIEC mice compared to controls. These findings suggested that altered tumor-associated gene expression and changed gut microbiota shape a tumor-preventive microenvironment to counteract the tumor-driving potential, leading to the tumor prevention in PtenDeltaIEC/DeltaIEC mice. PMID- 30292637 TI - Intracellular cholesterol accumulation and coenzyme Q10 deficiency in Familial Hypercholesterolemia. AB - Familial Hypercholesterolemia (FH) is an autosomal co-dominant genetic disorder characterized by elevated low-density lipoprotein (LDL) cholesterol levels and increased risk for premature cardiovascular disease. Here, we examined FH pathophysiology in skin fibroblasts derived from FH patients harboring heterozygous mutations in the LDL-receptor. Fibroblasts from FH patients showed a reduced LDL-uptake associated with increased intracellular cholesterol levels and coenzyme Q10 (CoQ10) deficiency, suggesting dysregulation of the mevalonate pathway. Secondary CoQ10 deficiency was associated with mitochondrial depolarization and mitophagy activation in FH fibroblasts. Persistent mitophagy altered autophagy flux and induced inflammasome activation accompanied by increased production of cytokines by mutant cells. All the pathological alterations in FH fibroblasts were also reproduced in a human endothelial cell line by LDL-receptor gene silencing. Both increased intracellular cholesterol and mitochondrial dysfunction in FH fibroblasts were partially restored by CoQ10 supplementation. Dysregulated mevalonate pathway in FH, including increased expression of cholesterogenic enzymes and decreased expression of CoQ10 biosynthetic enzymes, was also corrected by CoQ10 treatment. Reduced CoQ10 content and mitochondrial dysfunction may play an important role in the pathophysiology of early atherosclerosis in FH. The diagnosis of CoQ10 deficiency and mitochondrial impairment in FH patients may also be important to establish early treatment with CoQ10. PMID- 30292638 TI - The deficiency of macrophage erythropoietin signaling contributes to delayed acute inflammation resolution in diet-induced obese mice. AB - Obesity has been linked with altered acute inflammation resolution which contributes to obesity-related clinical complications; however, the mechanisms that contribute to obesity-related unresolved inflammation are not fully known. Here we demonstrated that the deficiency of macrophage erythropoietin (EPO) signaling contributed to delayed acute inflammation resolution in diet-induced obese mice. In zymosan-induced acute peritonitis, in line with the delayed resolution of inflammation, the induction of macrophage EPO signaling was significantly reduced in obese mice relative to normal mice. Exogenous EPO induced macrophage EPO signaling and promoted acute inflammation resolution in obese mice. Efferocytosis of apoptotic cells by macrophages which is central in inflammation resolution was impaired in obese mice and restored by exogenous EPO. Mechanistically, macrophage peroxisome proliferator-activated receptor-gamma (PPARgamma) was greatly reduced in obese mice and EPO increased macrophage PPARgamma to promote efferocytosis in obese mice. Together, our results identify an important mechanism underlying aberrant acute inflammation resolution in obesity, with important implications for regulating unresolved acute inflammation and normalizing macrophage defects in obese and diabetic individuals.

PMID- 30292643 TI - Diagnosis and management of pancreatic cancer in adults: A summary of guidelines from the UK National Institute for Health and Care Excellence. AB - To enable standardisation of care of pancreatic cancer patients and facilitate improvement in outcome, the United Kingdom's National Institute for Health and Care Excellence (NICE) developed a clinical guideline for the diagnosis and management of pancreatic cancer in adults. Systematic literature searches, systematic review and meta-analyses were undertaken. Recommendations were drafted on the basis of the group's interpretation of the best available evidence of clinical and cost effectiveness. There was patient involvement and public consultation. Recommendations were made on: diagnosis; staging; monitoring of inherited high risk; psychological support; pain; nutrition management; and the specific management of people with resectable-, borderline-resectable- and unresectable-pancreatic cancer. The guideline committee also made recommendations for future research into neoadjuvant therapy, cachexia interventions, minimally invasive pancreatectomy, pain management and psychological support needs. These NICE guidelines aim to promote best current practice and support and stimulate research and innovation in pancreatic cancer. PMID- 30292644 TI - Organotypic slice cultures of pancreatic ductal adenocarcinoma preserve the tumor microenvironment and provide a platform for drug response. AB - BACKGROUND: /Objective: The conventional models currently used to evaluate various anti-tumor therapeutic agents are not sufficient for representing human pancreatic ductal adenocarcinoma (PDA), which has a unique tumor microenvironment. We aimed to produce an organotypic slice culture model from human PDA that resembles the in vivo situation and to evaluate the responses of PDA slices to established cytotoxic drugs. METHODS: PDA tissues were obtained from 10 patients who underwent pancreatic resection. The tissues were sliced by a vibratome, and the tumor slices were then cultured. The viability of tumor slices during slice culture was evaluated using H&E and immunohistochemical staining, and stromal cells were demonstrated. The effects of cytotoxic drugs on PDA cell lines and slices were analyzed. RESULTS: Tumor slices maintained their surface areas and tissue viability for at least five days during culture. Preserved proliferation and apoptosis in tumor slices were observed by the expression of Ki 67 and cleaved caspase-3. Stromal cells including macrophages (CD68+ and CD163+), T cells (CD3+, CD8+, and FOXP3+), and myeloid cells (CD11b+) were present throughout the culture period. Staurosporine, gemcitabine, and cisplatin treatment of PDA cell lines and tumor slices exerted proportional cytotoxic effects in terms of MTT viability, tumor cell number, and Ki-67 and cleaved caspase-3 expression. CONCLUSIONS: Organotypic human PDA slice cultures preserved their viability and tumor microenvironment for at least five days during slice culture. PDA slice culture appears to be a feasible preclinical test model to assess the response to anti-tumor agents. PMID- 30292645 TI - Perceived control and quality of life among recipients of implantable cardioverter defibrillator. AB - BACKGROUND: Perceived control is strongly associated with health-related quality of life (HRQOL) among patients with chronic conditions, and it is possible to increase perceived control with appropriate intervention. Little is known about the relationship between perceived control and HRQOL in implantable cardioverter defibrillator (ICD) recipients. OBJECTIVES: To determine the relationship of perceived control with quality of life in ICD recipients and to determine predictors of perceived control in this population. METHODS: A total of 263 ICD recipients (63% male, age 61 +/- 14 years) completed the Control Attitude Scale Revised to measure perceived control and completed self-reported measures on potential correlates of perceived control (i.e., depressive symptoms, anxiety, social support, and ICD concerns). The EuroQol-5D was used to measure HRQOL. Regression analysis was used to determine predictors of perceived control and its relationship to HRQOL, controlling for covariates. RESULTS: Lower perceived control (beta = 0.30, p < .01), and higher levels of depression (beta = -0.30, p < .01) and anxiety (beta = -0.18, p < .05) predicted lower levels of HRQOL. Higher anxiety (beta = -0.17, p < .05), higher depression (beta = -0.23, p < .05), lower social support (beta = 0.26, p < .01), and higher ICD-related concerns (beta = -0.16, p < .05) independently predicted lower perceived control. CONCLUSIONS: Interventions targeting patients' ICD concerns and psychosocial factors before, and continuing after, ICD insertion are needed to improve ICD recipients' perceived control and, in turn, their HRQOL. PMID- 30292646 TI - Upregulation of miR-132 contributes to the pathophysiology of COPD via targeting SOCS5. AB - The role of microRNAs has been recently identified in chronic obstructive pulmonary disease (COPD). This study aimed to examine the role of miR-132 in the pathophysiology of COPD and to explore the underlying molecular mechanisms of miR 132 in COPD. MiR-132 and suppressor of cytokine signaling 5 (SOCS5) mRNA expression were detected by qRT-PCR. The number of CD4+ and CD8+ T cells was analyzed by flow cytometry. SOCS5 and epidermal growth factor receptor (EGFR) protein levels were determined by western blot. Interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha) concentrations were measured by ELISA. MiR-132 expression was up-regulated in the serum from COPD patients and smokers compared with nonsmoker controls. The number of CD8+ T cells was significantly increased in the serum from COPD patients and smokers. MiR-132 expression was negatively correlated with FEV1/FVC%, and positively correlated with CD8+ T cells (%). MiR-132 overexpression repressed SOCS5 expression via directly targeting SOCS5 3'UTR in human monocyte-like cells (THP-1), which was confirmed by luciferase reporter assay. MiR-132 overexpression increased EGFR protein levels and the concentrations of inflammatory cytokines (IL-1beta and TNF-alpha) in THP 1 cells, and these effects were attenuated by enforced expression of SOCS5. Further, cigarette smoke extract (CSE) treatment up-regulated miR-132 expression, down-regulated SOCS5 expression, and increased inflammatory cytokines levels, which was attenuated by miR-132 knockdown in THP-1 cells. Consistent findings were also found in the human bronchial epithelial cells (BEAS-2B). Collectively, our data implicated that miR-132 may promote inflammation in THP-1 and BEAS-2B cells at least via targeting SOCS5 in COPD. PMID- 30292647 TI - Structural and functional profiles of the gut microbial community in polycystic ovary syndrome with insulin resistance (IR-PCOS): a pilot study. AB - Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic disorder that affects 9-21% of reproductive-aged women. Affected women frequently display obesity, insulin resistance, and inflammation. Altered gut microbial community has been reported in PCOS and obese PCOS patients. However, the profile of the gut microbial community in insulin resistant PCOS (IR-PCOS) patients still remains unknown. In this study, next-generation sequencing based on the 16S rRNA gene was used to compare the gut microbial composition of women with IR-PCOS (n = 9, PCOS with insulin resistance), NIR-PCOS (n = 8, PCOS alone) and healthy controls (n = 8, HC). We assessed that the composition of the gut microbial communities in NIR-PCOS and IR-PCOS patients were significantly altered. The family Bacteroidaceae was prolific in the NIR-PCOS group and reached its highest level in the IR-PCOS group, while the Prevotellaceae dramatically decreased in PCOS patients, especially in the IR-PCOS group. Subsequent correlation analysis revealed that the increased clinical parameter levels, including insulin resistance, sex-hormones and inflammation, were positively associated with the abundance of Bacteroidaceae, but negatively associated with that of Prevotellaceae. In addition, IR-PCOS patients also displayed a significant difference in their amounts of Ruminococcaceae and Lachnospiraceae when compared to the NIR-PCOS group. Moreover, the functional prediction from PICRUSt revealed that 73 pathways are significantly changed in the gut microbial communities of PCOS patients. Specifically, 21 metabolism-associated pathways, including the steroid hormone biosynthesis and lipopolysaccharide biosynthesis pathways, are obviously changed in IR-PCOS when compared to NIR-PCOS and HC groups. Taking this into consideration, our present study suggests that the dysbiosis of gut microbial communities occurred most notably in IR-PCOS patients, and the difference in gut dysbiosis profile between the IR-PCOS and NIR-PCOS should be considered in clinical treatment for PCOS patients and future drugs development. PMID- 30292648 TI - Metabolic comparison of one-anastomosis gastric bypass, single-anastomosis duodenal-switch, Roux-en-Y gastric bypass, and vertical sleeve gastrectomy in rat. AB - BACKGROUND: One-anastomosis gastric bypass (OAGB) and single-anastomosis duodenal switch (SADS) have become increasingly popular weight loss strategies. However, data directly comparing the effectiveness of these procedures with Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (SG) are limited. OBJECTIVES: To examine the metabolic outcomes of OAGB, SADS, RYGB, and SG in a controlled rodent model. SETTING: Academic research laboratory, United States. METHODS: Surgeries were performed in diet-induced obese Long-Evans rats, and metabolic outcomes were monitored before and for 15 weeks after surgery. RESULTS: All bariatric procedures induced weight loss compared with sham that lasted throughout the course of the study. The highest percent fat loss occurred after OAGB and RYGB. All bariatric procedures had improved glucose dynamics associated with an increase in insulin (notably OAGB and SADS) and/or glucagon-like protein 1 secretion. Circulating cholesterol was reduced in OAGB, SG, and RYGB. OAGB and SG additionally decreased circulating triglycerides. Liver triglycerides were most profoundly reduced after OAGB and RYGB. Circulating iron levels were decreased in all surgical groups, associated with a decreased hematocrit value and increased reticulocyte count. The fecal microbiome communities of OAGB, SADS, and RYGB were significantly altered; however, SG exhibited no change in microbiome diversity or composition. CONCLUSIONS: These data support the use of the rat for modeling bariatric surgical procedures and highlight the ability of the OAGB to meet or exceed the metabolic improvements of RYGB. These data point to the likelihood that each surgery accomplishes metabolic improvements through both overlapping and distinct mechanisms and warrants further research. PMID- 30292649 TI - Sexual Health Education for Adolescent Males Who Are Interested in Sex With Males: An Investigation of Experiences, Preferences, and Needs. AB - PURPOSE: There is a dearth of research to inform sexual education programs to address sexual health disparities experienced by adolescent males who are interested in sex with males (AMSM). The current study sought to determine where AMSM receive sexual health information, clarify their preferences, and explore relations with sexual behavior. METHODS: AMSM (N = 207; ages 14-17) in the United States completed an online sexual health survey. Bivariate associations between sexual education exposure/preferences by sexual behavior were assessed using Fisher's exact tests and one-way analyses of variance. RESULTS: Eighty-nine (43%) participants reported no sexual contact with male partners, 77 (37%) reported sexual contact without condomless anal sex, and 41 (20%) reported condomless anal sex. Participants received sexual health information from their parents/guardians (n = 122, 59%), formal sources (n = 160, 78%), and the Internet (n = 135, 65%). The most commonly covered topics by parents/guardians and formal sources were how to say no to sex, how to prevent HIV and other sexually transmitted infections, and methods of birth control. The most common online-researched topics were how to safely have anal sex, the types of sex you can have with a male partner, how to use a condom, and how to use lubrication. Participants noted preferring a sexually-explicit online sexual health program that addresses male-male sex. CONCLUSIONS: Online sexual education programs that explicitly address male-male sex are needed. Tailored programs can help AMSM develop healthy sexual behaviors and decrease their HIV/STI risk. PMID- 30292650 TI - Endocrine and psychological stress response in simulated doctor-patient interactions in medical education. AB - BACKGROUND: Training of doctor-patient interactions by means of patient actors is considered a useful didactic tool in medical education. However, though students report it as being highly stressful little systematic research has verified this notion. AIMS: To assess the endocrine and psychological stress responses of students in the doctor vs. the observer role in simulated doctor-patient interactions. METHODS: Salivary cortisol and anxiety was assessed in N = 86 participants of a mandatory course on doctor-patient interactions on three consecutive days. During two of these days they were in the observer role and gave feedback to another student and on one of these days they were in the doctor role and were being given feedback. Saliva was sampled at 4 points in time per day: prior to interaction (T1); after watching the video of the interaction (T2); after feedback (T3); after observation of another interaction (T4). Assessments on observer days took place at the respective time points and at the same time of the day. 3-way mixed ANOVAs were computed with the factors "day of data sampling" (F1); "day with doctor role" (F2); "measurement time"(F3). RESULTS: Significant two-way interactions F1 * F2 and three-way interactions F1 * F2 * F3 were observed both for cortisol and for anxiety (all p < .001). Neither cortisol nor anxiety were related to task severity. Anxiety at T1 correlated with cortisol increase from T1 to T2 (r = .266; p = .013). DISCUSSION: Results confirm that playing the doctor role in a simulated doctor-patient interaction represents a significant stressor in medical students. Effect sizes considerably exceed those observed in laboratory stress. This brings about new questions regarding moderating factors, effects of repetitions and relationship to medical performance. The ecological validity of this stressor can also make it a useful tool in basic endocrine research. PMID- 30292651 TI - Genetic variation of the mineralocorticoid receptor gene (MR, NR3C2) is associated with a conceptual endophenotype of "CRF-hypoactivity". AB - Recently, the "conceptual endophenotype" approach has been proposed as a means to identify subgroups of patients affected by stress-related psychiatric disorders. Conceptual endophenotypes consist of patterns of psychological, biological, and symptomatic elements. We studied a sample of patients seeking help for psychosomatic and stress-related disorders (total N = 469), who were evaluated with a diagnostic instrument that integrates psychological and biological data to derive 13 endophenotypes, or Neuropattern. The goal of this study was to explore associations between common variations of the mineralocorticoid receptor gene (MR, NR3C2), and the 13 conceptual endophenotypes of Neuropattern, as well as with the respective biological and symptom measures. A common haplotype of the MR, comprised of two functional single nucleotide polymorphism (rs2070951 G/C & rs5522 A/G), was associated with the conceptual endophenotype CRF-hypoactivity, characterized by low cortisol levels at awakening and a symptom constellation often observed in atypical depression. Homozygous carriers of the G-A haplotype (haplotype 1), previously associated with reduced dispositional optimism, increased levels of rumination and higher risk for depression, more frequently endorsed this Neuropattern. In addition to the overall association between MR variation and CRF hypoactivity, we observed in the whole sample significant associations between MR haplotypes and cortisol awakening response patterns, as well as with symptoms that characterize the CRF hypoactivity endophenotype. If replicated, MR haplotype 1 might serve as a vulnerability marker for a disorder class characterized in biological terms by reduced cortisol levels, and in terms of symptom constellation by features often observed in atypical depression. PMID- 30292652 TI - The investigation of the pyrethroid insecticide lambda-cyhalothrin (LCT)-affected Ca2+ homeostasis and -activated Ca2+-associated mitochondrial apoptotic pathway in normal human astrocytes: The evaluation of protective effects of BAPTA-AM (a selective Ca2+ chelator). AB - Exposure to insecticides has been found to have deleterious effects on human health. Lambda-cyhalothrin (LCT), a mixture of isomers of cyhalothrin, is a pyrethroid insecticide routinely used in pest control programs. LCT was reported to cause neurotoxic effects in various models. However, the mechanism of underlying effect of LCT on cytotoxicity in normal human brain cells is still elusive. This study examined whether LCT affected Ca2+ homeostasis and Ca2+ related physiology in Gibco(r) Human Astrocytes (GHA cells), and explored whether BAPTA-AM (1,2-bis(2-aminophenoxy)ethane-N,N,N'N'-tetraacetic acid), a selective Ca2+ chelator, has protective effects on LCT-treated GHA cells. The data show that LCT (10-15 MUM) concentration-dependently induced cytotoxicity in both GHA cells and DI TNC1 normal rat astrocytes but only induced intracellular Ca2+ concentration ([Ca2+]i) rises in GHA cells. In terms of Ca2+ signaling in GHA cells, LCT-induced [Ca2+]i rises were reduced by removing extracellular Ca2+ and were inhibited by store-operated Ca2+ channel modulators (2-APB, econazole or SKF96365). In Ca2+-free medium, pretreatment with the endoplasmic reticulum Ca2+ pump inhibitor thapsigargin abolished LCT-induced [Ca2+]i rises. Conversely, incubation with LCT abolished thapsigargin-induced [Ca2+]i rises. Regarding cytotoxicity, LCT evoked apoptosis by regulating apoptotic protein expressions (Bax, BCl-2, cleaved caspase-9/-3). This apoptotic response was significantly inhibited by prechelating cytosolic Ca2+ with BAPTA-AM. Together, in GHA cells, LCT induced [Ca2+]i rises by inducing Ca2+ entry via store-operated Ca2+ channels and Ca2+ release from the endoplasmic reticulum. Moreover, BAPTA-AM has a protective effect on inhibiting LCT-activated mitochondrial apoptotic pathway. This study provided new insights into the molecular protective mechanism of LCT induced cytotoxicity in normal human astrocytes. PMID- 30292653 TI - Differential copper-induced death and regeneration of olfactory sensory neuron populations and neurobehavioral function in larval zebrafish. AB - Fish rely heavily on their sense of smell to maintain behaviors essential for survival, such as predator detection and avoidance, prey selection, social behavior, imprinting, and homing to natal streams and spawning sites. Due to its direct contact with the outside environment, the peripheral olfactory system of fish is particularly susceptible to dissolved contaminants. In particular, environmental exposures to copper (Cu) can cause a rapid loss of olfactory function. In this study, confocal imaging of double-transgenic zebrafish larvae with differentially labeled ciliated and microvillous olfactory sensory neurons (OSNs) were used to examine cell death and regeneration following Cu exposure. Changes in cell morphologies were observed at varying degrees within both ciliated and microvillous OSNs, including the presence of round dense cell bodies, cell loss and fragmentation, retraction or loss of axons, disorganized cell arrangements, and loss of cells and fluorescence signal intensity, which are all indicators of cell death after Cu exposure. A marked loss of ciliated OSNs relative to microvillous OSNs occurred after exposure to low Cu concentrations for 3 h, with some regeneration observed after 72 h. At higher Cu concentrations and 24-h exposures, ciliated and microvillous OSNs were damaged with increased severity of injury with longer Cu exposures. Interestingly, microvillous, but not ciliated OSNs, regenerated rapidly within the 72-h time period of recovery after death from Cu exposure, suggesting that microvillous OSNs may be replaced in lieu of ciliated OSNs. An increase in bromodeoxyuridine labeling was observed 24 h after Cu-induced OSN death, suggesting that increased proliferation of the olfactory stem cells replaced the damaged OSNs. Olfactory behavioral analyses supported our imaging studies and revealed both initial loss and restoration of olfactory function after Cu exposures. In summary, our studies indicate that following zebrafish OSN damage by Cu, regeneration of microvillous OSNs may occur exceeding ciliated OSNs, likely via increased proliferation of the cellular reservoir of neuronal OSC precursors. Transgenic zebrafish are a valuable tool to study metal olfactory injury and recovery and to characterize sensitive olfactory neuron populations in fish exposed to environmental pollutants. PMID- 30292654 TI - Prenatal exposure to organochlorine pesticides and early childhood communication development in British girls. AB - BACKGROUND: The developing brain is susceptible to exposure to neurodevelopmental toxicants such as pesticides. AIMS: We explored associations of prenatal serum concentrations of hexachlorobenzene (HCB), beta-Hexachlorocyclohexane (beta-HCH), 2,2-Bis(4-chlorophenyl)-1,1-dichloroethene (p,p'-DDE) and 2,2-Bis(4-chlorophenyl 1,1,1-trichloroethane (p,p'-DDT) with maternal-reported measures of verbal and non-verbal communication in young girls. STUDY DESIGN AND METHODS: We studied a sample of 400 singleton girls and their mothers participating in the Avon Longitudinal Study of Parents and Children (ALSPAC) using multivariable linear regression models adjusting for parity, Home Observation Measurement of the Environment (HOME) score, maternal age and education status, and maternal tobacco use during the first trimester of pregnancy. EXPOSURE AND OUTCOME MEASURES: Maternal serum samples (collected at median 15 wks. gestation [IQR 10, 28]) were assessed for selected organochlorine pesticide levels. Communication was assessed at 15 and 38 months, using adapted versions of the MacArthur Bates Communicative Development Inventories for Infants and Toddlers (MCDI). RESULTS: At 15 months, girls born to mothers with prenatal concentrations of HCB in the highest tertile had vocabulary comprehension and production scores approximately 16% (p = 0.007) lower than girls born to mothers with concentrations in the lowest tertile. This association varied by maternal parity in that the evidence was stronger for daughters of nulliparous mothers. At 38 months, girls born to mothers with prenatal concentrations of HCB in the highest tertile had mean adjusted intelligibility scores that were 3% (p = 0.03) lower than those born to mothers with concentrations in the lowest tertile; however, results did not vary significantly by parity. Maternal concentrations of beta-HCH and p,p'-DDE were not significantly associated with MCDI scores at 15 or 36 months. p,p'-DDT had an inconsistent pattern of association; a significant positive association was observed between p,p'-DDT with verbal comprehension scores at 15 months; however, at 38 months a significant inverse association was observed for p,p'-DDT with communicative scores. This inverse association for p,p'-DDT among older girls tended to be stronger among daughters of mothers who had lower depression scores. CONCLUSIONS: Organochlorine pesticide exposure in utero may affect communication development. PMID- 30292655 TI - Fluid-fluid level in postpartum pituitary microadenoma necrosis on MRI. PMID- 30292656 TI - Knee crepitus is not associated with the occurrence of total knee replacement in knee osteoarthritis - a longitudinal study with data from the Osteoarthritis Initiative. AB - OBJECTIVE(S): To investigate whether the presence of knee crepitus is associated with the occurrence of total knee replacement (TKR), quality of life and deficits in physical function at long-term. METHODS: Setting - This observational study uses longitudinal data (up to 4-year follow-up) from the Osteoarthritis Initiative (OAI). Participants - 4566 participants. Main Outcome Measure(s) - Logistic regression models were used to test if baseline knee crepitus is associated with the occurrence of TKR. Linear mixed models with adjustment for confounding variables (age, gender, BMI and Kellgren-Lawrence grade) were used to test the association between baseline knee crepitus and longitudinal changes in the pain, self-reported physical function, quality of life and performance-based function. RESULTS: The presence of knee crepitus at baseline does not predict the occurrence of TKR at 36 months (p=0.58 and 0.67 for right and left knees, respectively). The crepitus group presented a slightly knee extension strength decline from baseline to 48 months (p=0.03 for the right and 0.01 for the left knee; between group difference=2% for both right [95%CI=-0.12; -0.01] and left knees [95%CI=-0.13; -0.02]). CONCLUSION: The presence of knee crepitus is not associated with the occurrence of TKR in the following three years. Knee crepitus is associated with slightly declines in knee extension strength, but this does not seem to affect physical function and quality of life at long-term. PMID- 30292658 TI - Patients' expectations and satisfaction in subthalamic nucleus deep brain stimulation for Parkinson disease: 6-year follow-up. AB - OBJECTIVE: Patients' expectations are considered to play an important role in STN DBS. We explored the relationship between expectations, satisfaction and outcome 6 years after surgery. METHODS: 15 patients with Parkinson disease (9 males, mean age 60.5 +/- 6.4 years) undergoing STN DBS completed a modified PDQ-39 questionnaire (incorporating an assessment of patients' expected changes in addition to the standard quality of life items) preoperatively and at 6 years postoperatively. A satisfaction questionnaire accompanied the postoperative questionnaire. RESULTS: At 6 years follow-up, PDQ-39 scores were unchanged from preoperative scores except in the stigma domain which showed a significant improvement. There was no significant difference between the postoperatively rated expected PDQ-39 summary score and the postoperative actual PDQ-39 summary score. However, there was a significant difference between the preoperatively rated expected PDQ-39 summary score and the postoperative actual PDQ-39 summary score. Patients remained highly satisfied with the outcome of surgery (mean satisfaction score 83%). Satisfaction did not correlate with PDQ-39 summary scores, domain scores or fulfilment of expectations. The more satisfied patients (satisfaction >= 80%) changed their expectations so that their postoperatively rated expectations reflected a less favorable condition whereas no such change was seen in the less satisfied (satisfaction < 80%) patients. CONCLUSIONS: Patients remain highly satisfied with STN DBS 6 years after surgery although quality of life assessed by the PDQ-39 may return to baseline levels. Patients' expectations change over time and may influence patient satisfaction. Managing expectations before and after surgery plays an essential role in STN DBS. PMID- 30292657 TI - Long-Term Results After Endoscopic Resection of Colloid Cysts. AB - BACKGROUND: Endoscopic resection of colloid cysts is a widely accepted treatment option instead of microsurgery. However, there is still a debate about a potentially higher rate of incomplete resections and recurrence. OBJECTIVE: The aim of this retrospective study was to evaluate long-term results after endoscopic removal of colloid cysts. METHODS: Twenty patients underwent endoscopic treatment in our department. Eighteen patients agreed to follow-up examinations. In 17 patients, magnetic resonance images were obtained. RESULTS: Total cyst resection was achieved in 16 procedures. In 1 patient, only plexus coagulation and widening of the ipsilateral foramen of Monro were performed. In 3 patients, small remnants of the cyst membrane were left behind. Conversion to microsurgery became necessary in 1 patient. Mild temporary complications occurred in 6 patients. Preoperative symptoms were completely relieved in 16 patients and improved in 2 patients. The average follow-up period was 188 months. In the patient with plexus coagulation, the cyst did not change. Recurrence occurred in 2 of 3 patients with cyst remnants. To date, no cyst remnant or recurrence has caused any symptoms or required surgical treatment. CONCLUSIONS: Our results indicate that endoscopic treatment of colloid cysts is a safe and effective treatment option that provides excellent long-term results. However, we determined that a significant risk for recurrence exists when even small parts of the cyst capsule were left behind. Therefore, we advocate an attempt at total endoscopic cyst resection. PMID- 30292659 TI - Chiari 1 Malformation Surgery: Comparing Non-violation of the Arachnoid versus Arachnoid Opening and Thermocoagulation of the Tonsils. AB - OBJECTIVE: Evidence is lacking concerning the myriad surgical techniques for type 1 Chiari malformation. This study evaluated the impact of arachnoid violation with tonsil thermocoagulation during surgical craniovertebral junction decompression. METHODS: The evaluation included aspects of the neurologic examination and parameters of cerebrospinal fluid flow on magnetic resonance imaging during preoperative and postoperative periods. All patients underwent craniovertebral junction decompression and opening of the dura mater. Patients were divided into 2 study groups. Patients in group 1 did not undergo arachnoid violation. Patients in group 2 underwent tonsil manipulation and systematic opening of the fourth ventricle outlet. RESULTS: There were 16 patients enrolled in each group (total of 32 patients). Regarding clinical improvement, there were no significant differences between groups in the postoperative period. Group 2 had more adverse events (relative risk 2.45, 95% confidence interval 1.55-3.86). In terms of cerebrospinal fluid flow parameter analyses, patients in group 1 achieved better results (P < 0.05). CONCLUSIONS: For treatment of symptomatic type 1 Chiari malformation, craniovertebral junction decompression with arachnoid preservation (i.e., without tonsillar manipulation) seems more suitable than the addition of arachnoid opening and thermocoagulation of the tonsils.

PMID- 30292661 TI - Hemorrhagic Atypical Planum Sphenoidale Meningioma with Intermittent Vision Loss A Rare Presentation of Apoplexy. AB - BACKGROUND: Symptoms that mimic pituitary apoplexy may be encountered with other neoplastic or infectious lesions. CASE DESCRIPTION: This 38-year-old man presented with severe sudden-onset headache and relapsing and remitting vision loss. Radiographic imaging studies demonstrated radiographic features of a hyperdense, hemorrhagic mass in the sellar region. MRI revealed a 4-cm mass abutting the optic chiasm and compressing the pituitary. After 4-week follow-up surveillance MRI demonstrated near-complete resolution of the previously identified planum sphenoidale and suprasellar mass, the patient re-presented 13 months later with recurrent symptoms. MRI demonstrated recurrence of the mass. Given the broad differential diagnosis, an endoscopic endonasal biopsy was obtained; the findings were suggestive of a high-grade meningioma. The patient underwent elective resection of the extra-axial lesion via a frontotemporal approach. The lesion was identified as a hemorrhagic suprasellar atypical planum sphenoidale meningioma. Postoperatively, the patient's headaches improved significantly and his right-sided visual changes resolved. After adjuvant radiotherapy (5400 cGy in 30 fractions) to the surgical cavity 3 months later, at last follow-up 5 months postoperatively, the patient was at his neurologic baseline and denied any headaches or visual sequelae. CONCLUSIONS: As the most common benign intracranial tumors, meningiomas should remain in the differential for patients presenting with apoplectiform symptoms. PMID- 30292662 TI - Transsphenoidal Approach for Pituitary Adenomas in Elderly Patients. AB - INTRODUCTION: With a rapidly expanding elderly population in the United States, the incidence of pituitary adenomas in elderly will continue to rise. In this study, we aim to evaluate the safety and efficacy of transsphenoidal endoscopic endonasal resection for pituitary adenomas in the elderly population. METHODS: A retrospective review of 131 consecutive patients who underwent transsphenoidal endoscopic endonasal resection for pituitary adenomas at the University of Miami Hospital between 2012 and 2016 was performed. Preoperative, intraoperative, and surgical outcomes were analyzed in elderly (>70 years) versus nonelderly (<70 years) patients. RESULTS: Of the 131 patients, 23 of them were >70 years (18%), of which 14 were septuagenarians and 9 were octogenarians. Elderly patients were more likely to present with vision loss (80.8% vs. 56.6%; P = 0.013) and larger tumors on imaging (2.7 +/- 1.0 cm vs. 2.4 +/- 1.3 cm; P = 0.042). Overall surgical and endocrinologic outcomes between the 2 groups were similar. However, patients <70 years old were more likely to have a gross total resection (86.7% vs. 65.4%; P = 0.011), as well as transient diabetes insipidus (54.3% vs. 26.9% P = 0.012) and intraoperative cerebrospinal fluid leak (83.5% vs. 58.5%; P = 0.013). However, permanent postoperative complication rates were similar including rate of permanent diabetes insipidus (4.3% elderly vs. 12.1% adult), cerebrospinal fluid leak (8.7% elderly vs. 8.4% adult), and meningitis (4.3% elderly vs. 2.8% adult). There were no medical complications or deaths in our cohort. CONCLUSION: The transsphenoidal endoscopic endonasal approach can be a safe and effective technique for resection of pituitary adenomas in patients >70 years old with appropriate patient selection. PMID- 30292663 TI - Biomechanical Study of Novel Unilateral Fixation Combining Unilateral Pedicle and Contralateral Translaminar Screws in the Subaxial Cervical Spine. AB - INTRODUCTION: In several situations, the stability of the subaxial cervical spine is damaged and involves the lateral mass of 1 side; in these cases, a pedicle screw (PS) or lateral mass screw (LMS) may not be suitable for placement on the affected side. Therefore, salvage short-segment fixation with satisfactory stability is needed when bilateral fixation is not feasible. METHODS: Seven fresh frozen human cervical spine specimens were used to test the 3-plane range of motion (ROM) of the C4-C5 segment. Quasistatic 2-Nm flexibility testing was performed in the following sequence: 1) intact; 2) destabilization (using 3 column injury models) treated with bilateral mass screws (BMSs); 3) destabilization treated with a unilateral PS combined with a contralateral translaminar screw (UPS+CTLS); and 4) destabilization treated with bilateral PSs (BPSs). Then, a pullout strength test was performed for the PSs, LMSs, and translaminar screws (TLSs) using 7 isolated C4 and C5 vertebrae. RESULTS: The UPS+CTLS group showed no significant difference from the BMS group in the 3-plane ROM or from the BPS group in the axial rotation or flexion-extension ROM but showed a significantly greater lateral bending ROM than did the BPS group. The pullout strength test showed that both C4 and C5 TLSs had strength similar to that of LMSs but poorer than that of PSs. CONCLUSIONS: Fixation with the hybrid UPS+CTLS construct performed as well as BMS fixation in our biomechanical tests and may play a clinical role when BPS or BMS placement is not feasible for short segment fixation. PMID- 30292665 TI - Hypoxia-Inducible Factor 1alpha and AT-Rich Interactive Domain-Containing Protein 1A Expression in Pituitary Adenomas: Association with Pathological, Clinical, and Radiological Features. AB - BACKGROUND: Hypoxia-inducible factor (HIF) plays a major role in tumorigenesis and cancer progression. In hypoxic conditions, HIF is upregulated and has been shown to activate multiple genes required for cells to adapt to hypoxia. AT-rich interactive domain-containing protein 1A (ARID1A), a SWI/SNF (switch/sucrose nonfermentable) chromatin remodeling gene has context-dependent tumor-suppressive and oncogenic roles in cancer. We assessed the correlations between the expression and mutations of HIF1A and ARID1A in histopathologically confirmed pituitary adenomas. METHODS: We performed a retrospective analysis of 71 patients who had undergone surgery for pituitary adenoma. Patient demographic, radiological, and histopathological features were correlated with HIF1A and ARID1A expression. RESULTS: Most cases were HIF1A positive (62%). No significant correlation was found between HIF1A expression and age, gender, tumor size, bone erosion, hemorrhage, or Ki-67 index. An inverse correlation was demonstrated between HIF1A and cavernous sinus invasion (P = 0.035). ARID1A loss was found in 28.2% of pituitary adenomas. No significant correlation was found between ARID1A and any of the assessed variables. CONCLUSIONS: In our patient cohort, we found that most pituitary adenomas expressed HIF1A. To the best of our knowledge, we are the first to assess the presence of ARID1A loss in pituitary adenomas, which occurred in 28.2% of cases. No individual demographic, imaging, or histopathological feature was predictive of ARID1A. Likewise, with the exception of an increased incidence of cavernous sinus invasion, no correlation was found with HIF1A. Given the prognostic value of these markers in other malignancies, their frequency in pituitary adenomas warrants further exploration of their potential role in pituitary adenoma treatment and outcome. PMID- 30292664 TI - Disturbed Consciousness and Coma: Diagnosis and Management of Intracranial Hypotension Caused by a Spinal Cerebrospinal Fluid Leak. AB - OBJECTIVE: The diagnosis and treatment of intracranial hypotension associated with a spinal cerebrospinal fluid (CSF) leak, especially in comatose patients, have yet to be established. METHODS: Clinical manifestations, neuroimaging findings, and treatment outcomes in 11 patients (Glasgow Coma Scale score 10 +/- 4) were described and compared with 36 patients with normal consciousness. RESULTS: Patients with disturbed consciousness were diagnosed at a significantly older age (55 +/- 11 years; P < 0.001) than those without (42 +/- 8.8 years). Neuroimaging findings in patients with disturbed consciousness were characterized by a smaller midbrain-pons angle (7.8 +/- 10 degrees ; P < 0.001), brainstem swelling (122%; P = 0.002), and thicker subdural hematomas (16 +/- 7.0 mm degrees ; P < 0.001). Epidural blood patch (EBP) alone did not achieve sustained improvements in patients with disturbed consciousness but did in most patients without (94%; P = 0.001). Over the treatment course, 5 patients progressed to coma, which correlated with a high signal intensity on T2-weighted magnetic resonance imaging in the brainstem. Hematoma drainage before EBP caused neurologic deterioration in 2 patients. Simultaneous EBP after hematoma drainage achieved sustained improvements in 5 of 6 patients. Simultaneous microsurgical dural repair after hematoma drainage achieved more rapid improvements in 3 of 3 patients. CONCLUSIONS: Among patients with intracranial hypotension caused by a spinal CSF leak, disturbed consciousness may occur in elderly patients because of severe diencephalic-mesencephalic deformities. Simultaneous EBP after safe hematoma drainage is indicated for these patients. Alternatively, dural repair is indicated for patients for whom the spinal level of dural disease has been identified. Hematoma drainage before EBP is not recommended because it caused deterioration. PMID- 30292666 TI - Cord Splitting Access to Ventral Intradural Cysts of Cervicothoracic Junction and Thoracic Spine. AB - OBJECTIVE: Surgical treatment of ventrally located intradural cysts is difficult and controversial. Laminectomy with division of the denticulate ligaments and gentle cord mobilization remains the standard approach but risks further neurologic deterioration secondary to cord manipulation. Our purpose is to evaluate the safety and effectiveness of a midline cord-splitting approach as an alternative for treating ventral thoracic intradural cysts. METHODS: We describe 2 patients who were treated for ventral intradural cysts causing progressive and severe myelopathy. Under general anesthesia and continuous neurophysiologic monitoring, laminectomy, durotomy, and cord splitting through a midline approach gave direct access to both lesions. Cyst drainage was supplemented by a cystopleural shunt in 1 case. RESULTS: Cyst collapse and cord reexpansion were documented in both patients with a magnetic resonance imaging scan 1 week after surgery. In both cases there was a significant neurologic improvement, which was maintained 2 years postoperatively. Intraoperative monitoring recorded no loss of somatosensory or motor potentials during surgery. Follow-up magnetic resonance imaging scans 2 years postoperatively showed no evidence of cyst recurrence, and both patients remained neurologically improved and stable. CONCLUSIONS: We have been able to drain 2 ventral intradural cysts using a cord-splitting technique. This has allowed safe access to purely ventrally located lesions, which were inaccessible dorsally or dorsolaterally. By using this method we have been able to avoid a more invasive ventral transthoracic approach necessitating vertebrectomy and reconstruction and risking serious complications. PMID- 30292667 TI - Investigation of the Effect of Alemtuzumab in an Experimental Spinal Cord Trauma Model in Rats. AB - OBJECTIVE: Spinal cord injuries generate the most negative response to medical treatment among all general body injuries. This important morbidity is thought to be caused by a complex secondary damage mechanism. In the present study, we examined the neuroprotective effects of alemtuzumab in a spinal cord trauma model. METHODS: We divided 24 Long-Evans male rats into 4 groups (n = 6 per group). Laminectomy was performed at T5-T8 in all groups. Trauma was applied using the Yasargil temporary aneurysm clip for 60 seconds at these spinal cord levels in all groups, except for group 1. Next, 1 mg/kg of alemtuzumab was administered to each rat in groups 3 and 4. A functional evaluation was performed on days 1, 3, and 5 in groups 1, 2, and 4, and the rats were then sacrificed. The rats in group 3 were sacrificed on the third postoperative day to observe the early effects of alemtuzumab. The biochemical examination findings of malondialdehyde and glutathione in plasma and tissue samples and histopathological findings of the spinal cord were evaluated and compared by statistical analysis. RESULTS: The inflammatory findings in the trauma group were not seen in either group treated with alemtuzumab. The clinical motor examination and inclined plane test results were also significantly better in these groups. CONCLUSION: Our results have shown that alemtuzumab might prevent spinal cord injury after trauma and is a histopathologically and biochemically strong anti inflammatory, antioxidant, and neuroprotective agent. PMID- 30292668 TI - The Application of FLOW 800 ICG Videoangiography Color Maps for Neurovascular Surgery and Intraoperative Decision Making. AB - BACKGROUND: Indocyanine green (ICG) videoangiography can assess cerebral blood flow, but results are primarily qualitative. FLOW 800 software measures fluorescence dynamics and creates a semiquantitative color delay map for assessment of relative sequence of blood flow within the vasculature. METHODS: We retrospectively reviewed 23 consecutive patients for whom FLOW 800 ICG videoangiography was used. They harbored aneurysms, arteriovenous malformations (AVMs), dural arteriovenous fistula (dAVF), or hemangioblastoma. Patients' characteristics, FLOW 800 data, and clinical findings were recorded. Color map data were readily available intraoperatively and guided surgery. RESULTS: The cohort included 10 patients with AVMs, 11 with aneurysms, 1 with dAVF, and 1 with hemangioblastoma. Approximately two thirds of patients underwent intraoperative angiography. FLOW 800 data provided semiquantitative data regarding localization, flow status in major feeding arteries, and dominance of the arterialized draining veins for AVMs, more than data from ICG videoangiography alone. For complex aneurysms, color maps confirmed relative adequate flow in parent and branching vessels. For the foramen magnum dAVF, the location of the dominant transdural connection was appreciated only via flow analysis. Flow analysis created the blood flow map of a large complex solid brainstem hemangioblastoma and guided devascularization. All FLOW 800 findings agreed with intraoperative and postoperative angiography. CONCLUSIONS: ICG videoangiography with FLOW 800 analysis can provide semiquantitative and relative flow magnitude data that are efficient and noninvasive. This process helps identify early arterialized veins and their flow status during AVM and dAVF surgery and can confirm adequate relative flow within branching vessels during aneurysm surgery when clip-induced stenosis is suspected.

AB - Cordyceps militaris exo-polysaccharides (EPS) have been reported to possess many benefits, such as anti-tumor, anti-inflammatory and antioxidant activities. In this study, the production of EPS via cultivation in a bioreactor was investigated. Glucose and yeast extract were determined to be the most suitable carbon and nitrogen sources for EPS production. The appropriate levels of glucose and yeast extract were 40 g/L and 10 g/L, respectively, resulting in EPS production of 1.686 g/L in a submerged culture. In the stirred-tank fermentor, an agitation rate of 150 rpm and aeration rate of 1.5 vvm were the most effective for EPS production. Due to the anchoring of mycelial cells on the wall of fermentor, a repeated batch approach was used. EPS production of C. militaris could be enhanced to a maximum of 5.713 g/L, with a productivity of 476 mg/L/day in the second run. The repeated batch approach was expected to generate higher EPS production, increase EPS yield and productivity and further simplify cultivation operations for bio-industrial application. PMID- 30292671 TI - Optimization of the treatment conditions with glycogen synthase kinase-3 inhibitor towards enhancing the proliferation of human induced pluripotent stem cells while maintaining an undifferentiated state under feeder-free conditions. AB - The small molecule inhibitor CHIR99021 (CHIR) is well known as a selective glycogen synthase kinase-3 inhibitor. The purpose of our study was to optimize the conditions of CHIR supplementation that will enhance the proliferation of human induced pluripotent stem cells (hiPSCs) while maintaining their undifferentiated state under feeder-free conditions in adherent cultures for 4 days. Our results revealed that both of the timing and concentration of CHIR affected cell behaviors of hiPSCs, such as colony formation, cell proliferation, and differentiation. The addition of 1-3 MUM CHIR to hiPSCs cultures in the late 2-day period of a 4-day cultivation was effective in enhancing cell proliferation. Treatment with 3 MUM CHIR significantly enhanced cell proliferation, but led to differentiation of hiPSCs when the treatment was carried out over 4 days. Treatment with higher concentration of CHIR was also conducive to deviating hiPSCs from their undifferentiated state. Treatment with 10 MUM CHIR led to decreased expression of pluripotency-associated genes and increased level of mesoderm marker genes, but failed to provided any growth promoting effect. Interestingly, when treatment with 1 MUM CHIR was confined to the late 2-day period of a 4-day cultivation, cell proliferation was enhanced without detectable deviation from the undifferentiated state as evidenced by the expression levels of pluripotency-associated genes, e.g., OCT3/4, NANOG, SOX2, and REX1. Repeated use of 1 MUM CHIR in subcultures provided no adverse effect on the proliferation of hiPSCs. Our results indicated that carefully designed CHIR treatment allows for enhanced proliferation of hiPSCs. PMID- 30292672 TI - The use of a standardized Chinese herbal formula in patients with advanced lung cancer: a feasibility study. AB - OBJECTIVE: Increasing numbers of cancer patients are using Chinese herbs (CHs). However, differences among prior studies make it difficult to draw firm conclusions about the clinical usefulness of any specific CH formula. The primary objective of this study was to establish the acceptability of taking a standardized CH formula for patients with advanced lung cancer. The secondary objective was to identify any toxicities attributable to this CH formula and to measure changes in quality of life. METHODS: A single-arm, prospective study of a 6-week intervention with a selected CH formula in 15 patients with stage 4 nonsmall-cell lung cancer (NSCLC, Seventh American Joint Committee on Cancer TNM staging system). RESULTS: Patients with advanced lung cancer were interested in using the CH formula. Completion (93%) and adherence (98%) levels were very high and most patients perceived the CH treatment as easy to take and were willing to take the CHs used in the study again if it was available. About half of the patients reported adverse events, all of which were mild (Grade 1 or 2) and only a small minority (8%) were potentially related to CHs. No biochemical or hematological evidence of toxicity was observed. Overall, there were improvement in quality of life, and reduced feelings of tiredness and sleepiness. CONCLUSION: This study provides preliminary evidence that short-term use of a carefully selected and prepared CH formula in patients with stage 4 NSCLC is acceptable and safe. PMID- 30292673 TI - A mechanistic model for thiol redox dynamics in the organogenesis stage rat conceptus. AB - Precise control of the glutathione/glutathione disulfide (GSH/GSSG) redox balance is vital for the developing embryo, but regulatory mechanisms are poorly understood. We developed a novel, mechanistic mass-balance model for GSH metabolism in the organogenesis stage (gestational day 10.0-11.13) rat conceptus predicting the dynamics of 8 unique metabolites in 3 conceptal compartments: the visceral yolk sac (VYS), the extra-embryonic fluid (EEF) and the embryo proper (EMB). Our results show that thiol concentrations in all compartments are well predicted by the model. Protein synthesis is predicted to be a major efflux pathway for all amino acid precursors of GSH synthesis and an essential model element. Our model provides quantitative insights in the transport fluxes and enzymatic fluxes needed to maintain thiol redox balances under normal physiological conditions. This is crucial to further elucidate the mechanisms through which chemical exposure can perturb redox homeostasis, causing oxidative stress, and potentially birth defects. PMID- 30292674 TI - Erythropoietin-producing hepatocellular A7 triggering ovulation indicates a potential beneficial role for polycystic ovary syndrome. AB - BACKGROUND: The ovulatory dysfunction mechanisms underlying polycystic ovary syndrome (PCOS) are not completely understood. And the roles of EPHA7 and EPHA7 regulated pathway factors in the pathogenesis of anovulation remain to be elucidated. METHODS: We used human granulosa cells (hGCs) of PCOS and non-PCOS patients to measure EPHA7 and other target gene expressions. We performed in vitro experiments in KGN cells to verify the molecular mechanisms. Additionally, we conducted in vivo loss- and gain-of-function studies using EPHA7 shRNA lentivirus and recombinant EPHA7-Fc protein injection to identify the ovulation effects of EPHA7. FINDINGS: EPHA7 functions as a critically positive upstream factor for the expression of ERK1/2-mediated C/EBPbeta. This protein, in turn, induced the expression of KLF4 and then ADAMTS1. Moreover, decreased abundance of EPHA7 was positively correlated with that of its downstream factors in hGCs of PCOS patients. Additionally, a 1-week functional EPHA7 shRNA lentivirus in rat ovaries contributed to decreased numbers of retrieved oocytes, and a 3-week functional lentivirus led to menstrual disorders and morphological polycystic changes in rat ovaries. More importantly, we found that EPHA7 triggered ovulation in rats, and it improved polycystic ovarian changes induced by DHEA in PCOS rats. INTERPRETATION: Our findings demonstrate a new role of EPHA7 in PCOS, suggesting that EPHA7 is an effective target for the development of innovative medicines to induce ovulation.

PMID- 30292676 TI - Determination of the microbiological contamination in minced pork by culture dependent and 16S amplicon sequencing analysis. AB - Routine evaluation of bacterial contamination in minced pork is still mainly performed by the enumeration of indicator bacteria, including total aerobic colony count and E. coli, using standardized isolation methods. However, the bacterial community structure as well as the effect of the storage time and temperature on the aerobic plate count are largely unknown for this matrix. The aim of the study was to characterize the microbial community in minced pork by 16S rRNA amplicon sequencing compared to classical isolation methods combined with identification by Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI TOF MS) and 16S rRNA gene sequencing. Analysis of 14 unrelated samples showed that total aerobic counts determined at 30 degrees C and 7 degrees C showed no significant difference, but the richness was higher on PCA at 30 degrees C for 7 samples, equal in 5, and higher at 7 degrees C for 2 samples. Members of the genus Pseudomonas, along with the genera Brochothrix and Carnobacterium were commonly identified among both the mesophilic and psychrotrophic population. Comparing to 16S rRNA amplicon sequencing, some contrasting data were obtained. Except for Brochothrix spp. and Pseudomonas spp., that were abundant and always detected, genera obtained with the two methods in the same sample were not always the same. Comparison of different sample preparation techniques and DNA extraction methods demonstrated also in this matrix that different results on the microbial composition and complexity are obtained. Present data illustrate that the combined isolation and identification of isolates using MALDI TOF MS and 16S gene sequencing and overall community profiling using 16S rRNA amplicon sequencing provides complementary results and yields important insights into the complex relationship between microorganisms in a food. PMID- 30292677 TI - Predicting heat process efficiency in thermal processes when bacterial inactivation is not log-linear. AB - The food industry widely uses the F-value which considers microbial log-linear inactivation, while microbial heat inactivation may result in a non-log-linear inactivation pattern due to genetic or phenotypical heterogeneity. This may yield discrepancies in predicting microbial heat inactivation under dynamic conditions of heat treatment. In this paper, we suggest the calculation of the equivalent time of heat treatment at a given temperature to overcome these constraints. To validate our proposal, the heat inactivation of Bacillus pumilus, showing non-log linear behavior, was predicted for 4 different heat inactivation profiles and bacterial enumeration was performed to determine whether prediction errors were acceptable. When the proportion of residuals in an acceptable zone from 1 log (fail safe) to 0.5 log (fail dangerous) was greater or equal to 70%, the model was considered as acceptable for predictions of the tested data. The new approach gave four different temperature profiles, with 96, 85, 85 and 100% of the residuals in the acceptable zone, indicating satisfactory prediction. Thus the proposed practical alternative to simulate microbial heat inactivation kinetics is able to extend the F-value to non-log-linear inactivation patterns. PMID- 30292678 TI - Development and optimization of antifungal packaging for sliced pan loaf based on garlic as active agent and bread aroma as aroma corrector. AB - The aim of the present work was the development of antimicrobial films containing garlic extract to be applied as active packaging for preservative-free sliced pan loaf, with the goal of extending its shelf-life. First, the antimicrobial capacity of garlic extract, a compound used as active agent, was tested against Penicillium expansum by the disc diffusion method. The extract showed high antimicrobial activity, 0.1 MUL per Petri dish being the minimum inhibitory amount, and 0.25 MUL the minimum fungicidal amount. Bread aroma was also used to mask the pungent odour of garlic and it was confirmed to have no antimicrobial activity. Subsequently, polyethylene (PE) aqueous emulsion and ethylene-vinyl alcohol copolymer (EVOH) and zein hydroalcoholic solutions containing 0.25 and 0.5% (w/w per dry polymer) of garlic extract and bread aroma were used to coat PE films, producing PE/PE, PE/EVOH and PE/zein active films. The antimicrobial capacity of the films was studied in vitro against Penicillium expansum, and in vivo with natural sliced bread. The results showed that all the films presented some antimicrobial activity, PE film coated with zein containing 0.5% of garlic extract and bread aroma being the film presenting the best results, maintaining bread free of mould infection for 30 days. Sensory tests showed that the addition of 1% of bread aroma improved the sensory experience of consumers and also revealed good purchase intention. PMID- 30292675 TI - Ketogenic diets attenuate cyclooxygenase and lipoxygenase gene expression in multiple sclerosis. AB - BACKGROUND: Adapted ketogenic diet (AKD) and caloric restriction (CR) have been suggested as alternative therapeutic strategies for inflammatory, hyperproliferative and neurodegenerative diseases. Pro-inflammatory eicosanoids have been implicated in the pathogenesis of multiple sclerosis since they augment vascular permeability and induce leukocyte migration into the brain. We explored the impact of ketogenic diets on gene expression of biosynthetic enzymes for pro- (ALOX5, COX1, COX2) and anti-inflammatory (ALOX15) eicosanoids in patients with relapsing-remitting multiple sclerosis. METHODS: 60 adults were prospectively recruited for this six months randomized controlled trial and the impact of dietary treatment on the Multiple Sclerosis Quality of Life-54 index (ClinicalTrials.gov (NCT01538355) has previously been published. Here we explored 24 patients (8 controls, 5 on CR and 11 on AKD). For statistical analysis we combined the two diet groups to a single pooled treatment group. FINDINGS: Inter group comparison indicated that expression of the pro-inflammatory ALOX5 in the pooled treatment group was significantly (p < 0.05) reduced when compared with the control group. Moreover, intra-group comparison (same individuals before and after dietary treatment) suggested significantly impaired expression of other pro inflammatory enzymes, such as COX1 (p < 0.001) and COX2 (p < 0.05). Finally, pretreatment cross-group analysis revealed a significant positive correlation between expression of pro-inflammatory ALOX5 and COX2 and an inverse correlation of ALOX5 and COX1 expression with the MSQoL-54 index. INTERPRETATION: Ketogenic diets can reduce the expression of enzymes involved in the biosynthesis of pro inflammatory eicosanoids. Pharmacological interference with eicosanoid biosynthesis might constitute a strategy supplementing current therapeutic approaches for MS. PMID- 30292679 TI - Micro patterning of hydroxyapatite by soft lithography on hydrogels for selective osteoconduction. AB - Mechanically robust hydrogels are promising biomaterials as artificial supportive tissue. These applications require selective and robust bonding of the hydrogels to living tissue. Recently, we achieved strong in vivo bone bonding of a tough double network (DN) hydrogel, a potential material for use as artificial cartilage and tendon, by hybridizing osteoconductive hydroxyapatite (HAp) in the gel surface layer. In this work, we report micro patterning of HAp at the surface of the DN hydrogel for selective osteoconduction. Utilizing the dissolution of HAp in an acidic environment, the soft lithography technique using an acid gel stamp was adopted to form a high-resolution HAp pattern on the gel. The HAp patterned gel showed well-regulated migration and adhesion of cells in vitro. Moreover, the HAp-patterned gel showed selective and robust bonding to the rabbit bone tissue in vivo. This HAp soft lithography technique allows for simple and quick preparation of tailor-made osteoconductive hydrogels and can be applied to other hydrogels for selective bone bonding. STATEMENT OF SIGNIFICANCE: Hydrogels, preserving large amount of water, have been studied for next-generation artificial soft tissues. However, fixation of hydrogels to living tissue was unsolved issue for clinical application. Recently, we achieved robust bonding of a tough double network gel to bone in vivo by coating of osteoconductive hydroxyapatite in the gel surface layer. For further progress for practical use, we report the micro patterning of HAp at the surface of the DN hydrogel by using soft lithography technique, to perform selective bonding to only objective area without unnecessary coalescence. The HAp lithography technique is simple, quick and non-toxic method to prepare tailor-made osteoconductive hydrogels and has universality of species of hydrogels. PMID- 30292680 TI - Significance of preoperative acute kidney injury in patients with acute type A aortic dissection. AB - BACKGROUND/PURPOSE: Acute type A aortic dissection (AAD) is a medical emergency with high mortality even with emergency repair. We explored the risk factors for in-hospital mortality and the impact of preoperative acute kidney injury (AKI) in patients with AAD. METHODS: Our hospital database contained records for 156 consecutive patients who underwent AAD repair between March 2000 and February 2013. They were assigned to the in-hospital mortality or the survival group. All data were collected retrospectively. RESULTS: The 30-day mortality, including intraoperative deaths, was 14.1% (22/156). Total in-hospital mortality was 19.2% (30/156). Patients who required preoperative cardiopulmonary resuscitation (CPR) (16.7 vs 3.2%; P = 0.012), or who presented with preoperative cardiac tamponade (46.7 vs 19.0%; P = 0.002), shock/hypotension (56.7 vs 21.4%; P < 0.001), or coma (20.0 vs 6.3%; P = 0.019) had a higher in-hospital mortality rate. There was no difference in in-hospital mortality rate between patients with preoperative AKI or not. Mortality and major complications were significantly correlated with the severity of AKI. Multivariate analysis confirmed that preoperative shock or hypotension (odds ratio = 5.2; 95% CI = 2.2-12.3), and preoperative AKI stage 3 (odds ratio = 4.9; 95% CI = 1.3-19.3) were independent preoperative prognostic factors of in-hospital mortality. CONCLUSION: On the basis of our results, preoperative stage 3 AKI is a crucial prognostic risk factor for patients with AAD repair, Cardiac surgeons should be aware of this condition when dealing with AAD patients. PMID- 30292681 TI - Skewed ratio between type 1 and type 2 calreticulin mutations in essential thrombocytosis patients with concomitant Janus kinase 2 V617F mutation. AB - Detection of somatic mutations in cardinal driver genes is a strong argument for diagnosis in classical Philadelphia-negative myeloproliferative neoplasms (MPNs). Driver mutations in Janus kinase 2 (JAK2), calreticulin (CALR), and XXXX (MPL), are generally considered mutually exclusive, but several reports have suggested that they coexist in a small subgroup of patients. In this study, we retrospectively searched for CALR mutations in 136 suspected MPN patients with low allelic burden (<=5%) JAK2 V617F. Fifteen patients with concomitant JAK2 V617F and CALR mutations were identified, of whom 10 were diagnosed with essential thrombocytosis (ET). More than 50 different indel mutations in exon 9 of CALR have been reported, with type 1 (52 bp deletion) and type 2 (5 bp insertion) accounting for more than 80% of CALR-mutated MPN cases. Type 1 is generally considered the most common mutation, but, interestingly, our double mutated ET patients seem to have an inversed ratio between type 1 and type 2 CALR mutations. Our findings support the possibility of coexisting JAK2 V617F and CALR mutations and stress the importance of further molecular screening in MPN patients with low allele frequencies of JAK2 V617F. PMID- 30292682 TI - 2-Cys Peroxiredoxins Participate in the Oxidation of Chloroplast Enzymes in the Dark. AB - Most redox-regulated chloroplast enzymes are reduced during the day and oxidized during the night. While the reduction mechanism of light-dependent enzymes is well known, the mechanism mediating their oxidation in the dark remains unknown. The thiol-dependent peroxidases, 2-Cys peroxiredoxins (Prxs), play a key role in light-dependent reduction of chloroplast enzymes. Prxs transfer reducing equivalents of thiols to hydrogen peroxide, suggesting the participation of these peroxidases in enzyme oxidation in the dark. Here, we have addressed this issue by analyzing the redox state of well-known redox-regulated chloroplast enzymes in response to darkness in Arabidopsis thaliana mutants deficient in chloroplast localized Prxs (2-Cys Prxs A and B, Prx IIE, and Prx Q). Mutant plants lacking 2 Cys Prxs A and B, and plants overexpressing NADPH-dependent thioredoxin (Trx) reductase C showed delayed oxidation of chloroplast enzymes in the dark. In contrast, the deficiencies of Prx IIE or Prx Q exerted no effect. In vitro assays allowed the reconstitution of the pathway of reducing equivalents from reduced fructose 1,6-bisphosphatase to hydrogen peroxide mediated by Trxs and 2-Cys Prxs. Taken together, these results suggest that 2-Cys Prxs participate in the short term oxidation of chloroplast enzymes in the dark. PMID- 30292683 TI - Medicago AP2-Domain Transcription Factor WRI5a Is a Master Regulator of Lipid Biosynthesis and Transfer during Mycorrhizal Symbiosis. AB - Most land plants have evolved a mutualistic symbiosis with arbuscular mycorrhiza (AM) fungi that improve nutrient acquisition from the soil. In return, up to 20% of host plant photosynthate is transferred to the mycorrhizal fungus in the form of lipids and sugar. Nutrient exchange must be regulated by both partners in order to maintain a reliable symbiotic relationship. However, the mechanisms underlying the regulation of lipid transfer from the plant to the AM fungus remain elusive. Here, we show that the Medicago truncatula AP2/EREBP transcription factor WRI5a, and likely its two homologs WRI5b/Erf1 and WRI5c, are master regulators of AM symbiosis controlling lipid transfer and periarbuscular membrane formation. We found that WRI5a binds AW-box cis-regulatory elements in the promoters of M. truncatula STR, which encodes a periarbuscular membrane localized ABC transporter required for lipid transfer from the plant to the AM fungus, and MtPT4, which encodes a phosphate transporter required for phosphate transfer from the AM fungus to the plant. The hairy roots of the M. truncatula wri5a mutant and RNAi composite plants displayed impaired arbuscule formation, whereas overexpression of WRI5a resulted in enhanced expression of STR and MtPT4, suggesting that WRI5a regulates bidirectional symbiotic nutrient exchange. Moreover, we found that WRI5a and RAM1 (Required for Arbuscular Mycorrhization symbiosis 1), which encodes a GRAS-domain transcription factor, regulate each other at the transcriptional level, forming a positive feedback loop for regulating AM symbiosis. Collectively, our data suggest a role for WRI5a in controlling bidirectional nutrient exchange and periarbuscular membrane formation via the regulation of genes involved in the biosynthesis of fatty acids and phosphate uptake in arbuscule-containing cells. PMID- 30292684 TI - New insights into the pathophysiology of fasciculations in amyotrophic lateral sclerosis: An ultrasound study. AB - OBJECTIVE: To describe the fasciculation pattern in ALS and to analyse its clinical and pathophysiological significance. METHODS: Ultrasound of 19 muscles was performed in 44 patients with a recent diagnosis (<90 days) of ALS. The number of fasciculations was recorded in each muscle and the muscle thickness and strength were additionally measured in limb muscles. A subgroup of patients were electromyographically assessed. RESULTS: US was performed in 835 muscles and EMG was available in 263 muscles. US detected fasciculations more frequently than EMG. Fasciculations were widespread, especially in upper limbs onset patients and in the cervical region. Fasciculations' number inversely associated with ALSFR-R and body mass index (BMI) and directly with BMI loss and upper motor neuron (UMN) impairment. Our statistical model suggest that fasciculations increase with the initial lower motor neuron (LMN) degeneration, reach their peak when the muscle became mildly to moderately weak, decreasing afterwards with increasing muscle weakness and atrophy. CONCLUSIONS: Our study suggests that both UMN and LMN degeneration trigger fasciculations causing BMI loss. The degree of LMN impairment could account for differences in fasciculations' rates within and between muscles. SIGNIFICANCE: In ALS, fasciculations could explain the link between hyperexcitability and BMI loss. PMID- 30292685 TI - Criteria wanted. Is the brain dead or alive?

PMID- 30292688 TI - Nickel spiking to improve the methane yield of sewage sludge. AB - The presence of micro-nutrients can be stimulatory for the anaerobic digestion (AD) of hardly degradable wastes and thus, improve process performance. Among the essential trace elements, nickel is involved in multiple important enzymes necessary for efficient AD. The present study investigates the effect of nickel spiked sewage sludge on batch and continuous mode operation. Metal spiking was conducted in the form of nanoparticles (Ni-NPs) and salt (NiCl2.6H2O). Results from batch assays showed that 5 mgNi-Salt/kgVS in the presence of Nitrilotriacetic acid (NTA) enhanced the methane yield by ~10% compared to the untreated sample. The impact of Ni-NPs in the AD process was also positive, but slightly lower compared to the effect of NiCl2.6H2O. The stimulatory impact of Ni was also revealed in continuously fed digester boosting the methane yield by ~8%. Overall, the improved methane production indicated that methanogenic archaea were favoured by the simultaneous supplementation of Ni and NTA. PMID- 30292689 TI - Bidirectional extracellular electron transfers of electrode-biofilm: Mechanism and application. AB - The extracellular electron transfer (EET) between microorganisms and electrodes forms the basis for microbial electrochemical technology (MET), which recently have advanced as a flexible platform for applications in energy and environmental science. This review, for the first time, focuses on the electrode-biofilm capable of bidirectional EET, where the electrochemically active bacteria (EAB) can conduct both the outward EET (from EAB to electrodes) and the inward EET (from electrodes to EAB). Only few microorganisms are tested in pure culture with the capability of bidirectional EET, however, the mixed culture based bidirectional EET offers great prospects for biocathode enrichment, pollutant complete mineralization, biotemplated material development, pH stabilization, and bioelectronic device design. Future efforts are necessary to identify more EAB capable of the bidirectional EET, to balance the current density, to evaluate the effectiveness of polarity reversal for biocathode enrichment, and to boost the future research endeavors of such a novel function. PMID- 30292690 TI - Replicative aging as a source of cell heterogeneity in budding yeast. AB - While deviations from the optimal phenotype are deleterious, increased variation can prevent population extinction under severe stresses. Cell division asymmetry is an important source of microbial phenotypic heterogeneity. A consecutive set of asymmetric divisions can cause the gradual accumulation of deleterious factors and, at late stages, the death of old pole (mother) cells. This phenomenon is known as replicative aging. As the old cells are constantly being diluted by the progeny, the majority of a microbial population is represented by replicatively young cells. Therefore, early-age changes in yeast mother cells have a much greater impact on the integral performance of the microbial population than does functional deterioration at later ages. Here, we review the early manifestations of replicative aging in Saccharomyces cerevisiae mother cells that occur during the first ten cell cycles. Early age-dependent changes occur in stress resistance, genomic instability, protein aggregate levels, redox balance and metabolism. We speculate that some of these manifestations can be beneficial during stress exposure; therefore, early aging may be a bet-hedging mechanism. Together, the data suggest that the age component of variation in populations of asymmetrically dividing microorganisms is substantial and may play an important role in adaptations to changing environments. PMID- 30292691 TI - Toxicity of lupane derivatives on anionic membrane models, isolated rat mitochondria and selected human cell lines: Role of terminal alkyl chains. AB - Triterpenoids have multiple biological properties, although little information is available regarding their toxicity. The present study evaluates the toxicity of two new synthetic lupane derivatives using distinct biological models including synthetic lipids membranes, isolated liver and heart mitochondria fractions, and cell lines in culture. The two novel triterpenoids caused perturbations in the organization of synthetic lipid bilayers, leading to changes in membrane fluidity. Inhibition of cell proliferation and mitochondrial and nuclear morphological alterations were also identified. Inhibition of mitochondrial oxygen consumption, transmembrane electric potential depolarization and induction of the mitochondrial permeability transition pore was observed, although effects on isolated mitochondrial fractions were tissue-dependent (e.g. liver vs. heart). The size and length of hydrocarbon chains in the two molecules appear to be determinant for the degree of interaction with mitochondria, especially in the whole cell environment, where more barriers for diffusion exist. The results suggest that the positively charged triterpenoids target mitochondria and disrupt bioenergetics. PMID- 30292692 TI - Reliability of microvascular responsiveness measures derived from near-infrared spectroscopy across a variety of ischemic periods in young and older individuals. AB - BACKGROUND: Cardiovascular disease (CVD) is associated with impairments in microvascular responsiveness. Therefore, reliably assessing microvascular function is clinically relevant. Thus, this study aimed to examine the reliability of the near-infrared spectroscopy (NIRS)-derived oxygen saturation (StO2) reperfusion slope, a measure of microvascular responsiveness, to four different vascular occlusion tests (VOT) of different durations in young and older participants. METHODS: Eight healthy young (29 +/- 5 yr) and seven older (67 +/- 4 yr) men participated in four NIRS combined with VOT (NIRS-VOT; 30 s, 1, 3, and 5 min) in the leg microvasculature on two visits separated by 1-2 weeks. Vascular responsiveness was determined by the StO2 reperfusion slope. The coefficient of variation (CV), repeatability, reliability (ICC), and the limits of agreement (LOA) were calculated for the NIRS-derived reperfusion slopes for each occlusion duration and visit. RESULTS: CV for the StO2 reperfusion slope following 30 s, 1, 3 and 5 min of occlusion were 33 +/- 29%, 19 +/- 21%, 14 +/- 12%, and 12 +/- 10%, respectively. Repeatability values following 30 s, 1, 3 and 5 min occlusions were 20%, 1%, 4% and 21%, respectively. The ICC for the StO2 reperfusion slopes for each occlusion duration were 0.29, 0.42, 0.84, and 0.88 following 30 s, 1, 3 and 5 min of occlusion, respectively. LOA values between visit 1 and 2 for occlusions were not different from zero. There were no age related differences for all variables of the study. CONCLUSION: NIRS-derived StO2 reperfusion slope, has good reliability across a range of occlusion durations with the strongest reliability during longer occlusion durations. PMID- 30292693 TI - Ragweeds and relatives: Molecular phylogenetics of Ambrosiinae (Asteraceae). AB - Ambrosiinae are one of the most distinct subtribes in the Heliantheae alliance (Asteraceae), mainly due to specialization toward wind pollination. Taxa of the subtribe are principally native to the Americas, although some species have attained a cosmopolitan distribution. Members of subtribe Engelmanniinae are considered close to Ambrosiinae, due to shared morphological traits. However, the placement of Ambrosiinae within the Heliantheae alliance has not yet been corroborated by phylogenetic analyses. In the present study, we test the circumscription of subtribe Ambrosiinae and examine relationships among its genera. We used sequence information from three plastid (psbA-trnH, trnQ-rps16 and trnL-F) and two nuclear (ITS and D35) marker regions. Phylogenetic inference analyses were conducted, applying Bayesian Inference (BI) and Maximum Likelihood (ML). Subtribe Ambrosiinae is found monophyletic or nearly so in all analyses. The genera Dugesia and Rojasianthe (previously considered part of subtribe Engelmanniinae) in some cases cluster together with Ambrosiinae; these genera are clearly not part of Engelmanniinae. Within Ambrosiinae, the genera Parthenium and Parthenice occupy basal positions, whereas members of the genus Ambrosia are the most derived representatives of the subtribe. Previous subdivision of Ambrosiinae into "Iveae" (members having androgynous capitula and free achenes) and "Ambrosieae" (genera with unisexual heads and achenes enclosed in burs) is not corroborated. Results also allow consideration of relationships among species and subgeneric groups within Parthenium, Iva, and Ambrosia. PMID- 30292694 TI - Phenotypic and life-history diversification in Amazonian frogs despite past introgressions. AB - The advent of genomics in phylogenetics and population genetics strengthened the perception that conflicts among gene trees are frequent and often due to introgression. However, hybridization occurs mostly among species that exhibit little phenotypic differentiation. A recent study delineating species in Anomaloglossus, a frog genus endemic to the Guiana Shield, identified an intriguing pattern in the A. baeobatrachus species complex. This complex occurs in French Guiana and Amapa (Brazil) and comprises two sympatric phenotypes contrasting not only in body size, habitat, and advertisement call, but also in larval development mode (endotrophic vs exotrophic tadpoles). However, molecular and phenotypic divergences are, in some cases, incongruent, i.e specimens sharing mtDNA haplotypes are phenotypically distinct, suggesting a complex evolutionary history. Therefore, we genotyped 106 Anomaloglossus individuals using ddRADseq to test whether this phenotype/genotype incongruence was a product of phenotypic plasticity, incomplete lineage sorting, multiple speciation events, or admixture. Based on more than 16,000 SNPs, phylogenetic and population genetic approaches demonstrated that exotrophic populations are paraphyletic. Species tree and admixture analyses revealed a strikingly reticulate pattern, suggesting multiple historical introgression events. The evolutionary history of one exotrophic population in northern French Guiana is particularly compelling given that it received genetic material from exotrophic ancestors but shows very strong genetic affinity with the nearby endotrophic populations. This suggests strong selection on larval development and mating call after secondary contact and hybridization. The case of A. baeobatrachus represents a striking example of introgression among lineages that are phenotypically distinct, even in their larval development mode, and highlights how high-resolution genomic data can unravel unexpectedly complex evolutionary scenarios.

PMID- 30292697 TI - The dynamic-lymphaticovenular anastomosis method for breast cancer treatment related lymphedema: Creation of functional lymphaticovenular anastomoses with use of preoperative dynamic ultrasonography. AB - BACKGROUND: Lymphaticovenular anastomosis (LVA) is generally an effective procedure for breast cancer treatment-related upper extremity lymphedema (UEL). Clinical improvement is, however, limited by the degree of sclerosis of the lymphatic vessels. We have developed a method by which we use dynamic ultrasonography to depict vessels through which lymph can be propelled into the LVA under the power of the patient's natural hand movements. METHODS: We assessed the dynamic-LVA method by comparing clinical details of 15 cases of breast cancer treatment-related lymphedema treated by dynamic LVA and 15 corresponding cases treated by conventional LVA. RESULTS: Placement of incisions at a total of 90 forearm sites (three per patient) yielded 90 LVAs (32 in "linear ICG lymphography pattern incisions" and 58 in "stardust pattern incisions"). Sclerotic lymphatic vessels were encountered at greater frequency in "linear pattern incisions" in the dynamic LVA group than in the conventional LVA group (7.1% vs. 38.9%, P = 0.030). Postoperative volume reduction was significantly greater in the dynamic LVA group than in the conventional LVA group; the UEL index at 1 month was 8.12 +/- 3.08 vs. 3.74 +/- 5.82, respectively (P = 0.018), and at 1 year was 10.23 +/- 6.16 vs. 2.03 +/- 9.36, respectively (P = 0.014). CONCLUSIONS: Dynamic LVA is clinically beneficial because the imaging guides decisions over the locations where the incisions should be placed so that a patient's natural hand motions can be used to propel lymph into the anastomosis despite the presence of sclerosis and because even early improvements are obtained. PMID- 30292696 TI - Variation in the perioperative care of women undergoing abdominal-based microvascular breast reconstruction in the United Kingdom (The optiFLAPP Study). AB - INTRODUCTION: Abdominal-based microvascular breast reconstruction constitutes approximately one-fifth of reconstructions following mastectomy for breast cancer. Enhanced recovery after surgery (ERAS) protocols have been implemented to improve patient care. The aim of this project was to identify variation in the perioperative care of women undergoing microvascular breast reconstruction to inform development of an ERAS protocol. METHODS: Surveys were developed for plastic surgeons, anaesthetists and the lead clinician for breast reconstruction at each unit. These assessed most aspects of perioperative care. A team of medical student collaborators was identified. This team created a list of surgeons and anaesthetists in the United Kingdom by unit. REDCap was used to record their responses. RESULTS: Nineteen (19/39, 49%) lead clinicians, 83 (83/134, 62%) plastic surgeons and 71 (71/100, 71%) anaesthetists from units across the UK completed the surveys. Marked variation was identified in the clinician responses when compared with the national and international guidelines. This variation covered many aspects of patient care including antibiotic and fluid prescribing, surgical technique, post-operative care and recording of patient outcomes. CONCLUSIONS: The optiFLAPP national practice survey has demonstrated variation in the perioperative care of women undergoing abdominal based microvascular breast reconstruction. We propose a large prospective audit to assess current protocols and support development of randomised controlled trials.

AB - In this communication we present a novel pig atlas model which is represented by a parametric linear Lagrange or cubic Hermite mesh. The model is developed from data points digitized from a 3D pig CT image. In total 84 muscles and 121 bones are included in the atlas, representing the tissue structures most relevant to the industry. We discuss its potential applications in virtual meat cuts and statistical shape analysis for pig breeding and genetics companies. PMID- 30292699 TI - Influence of extending the pre-slaughter interval after second vaccination on the carcass cutting yield and the quality of meat from immunocastrated lambs. AB - The influence of extending the vaccination-to-slaughter interval of immunocastrated lambs on carcass cutting yield and meat quality of the Longissimus thoracis (LT) muscle was investigated in forty Dohne Merino lambs (8.5 months old; 53.7 +/- 4.8 kg). Immunocastration booster vaccination intervals of six (IC6; n = 10) and four (IC4; n = 10) weeks prior to the slaughter age were used, with two weeks between primary and secondary vaccinations. A further 10 lambs were Burdizzo-castrated at 6.5 months old (B). The control treatment remained intact (R; n = 10). Prime cutting yields, LT muscle area, LT subcutaneous fat thickness and instrumental meat quality were accessed. Both castration methods increased LT fat thickness and decreased meat CIE a* (redness) values. Extending the vaccination-to-slaughter interval of immunocastrates increased the gastrointestinal tract fat and decreased meat redness. Immunocastration of male lambs can thus be used to manipulate backfat without negatively influencing carcass weight, cutting yield or meat quality.

AB - Nutrition research continues to be important for consumers to make informed food purchasing decisions and is used in nutrition policy decisions. The objective of this study was to analyze the nutrient concentration of raw and cooked cuts from special-fed veal calves to update nutrient data in the USDA National Nutrient Database for Standard Reference (SR) Release 27. Packages of wholesale (whole loin roasts, center-cut hindshanks and ground veal) and retail veal cuts (osso buco foreshanks, loin chops, leg cutlets and shoulder blade chops) were randomly collected in original vacuum packaging from six U.S. suppliers. Packages were shipped to the Colorado State University Meat Laboratory for cut dissection, cooking, and nutrient analysis. Composites of lean, external fat and seam fat were formed for analysis of proximate, fatty acid, vitamin and mineral composition. Results from this study identified additional fatty acids, established choline concentration, and provided updated veal nutrient composition information for inclusion in USDA SR 27.

PMID- 30292702 TI - The external genitalia in juvenile Caiman latirostris differ in hormone sex determinate-female from temperature sex determinate-female. AB - The broad-snouted caiman (Caiman latirostris) is a crocodilian species that inhabits South American wetlands. As in all other crocodilians, the egg incubation temperature during a critical thermo-sensitive window (TSW) determines the sex of the hatchlings, a phenomenon known as temperature-dependent sex determination (TSD). In C. latirostris, we have shown that administration of 17 beta-estradiol (E2) during the TSW overrides the effect of the male-producing temperature, producing phenotypic females (E2SD-females). Moreover, the administration of E2 during TSW has been proposed as an alternative way to improve the recovery of endangered reptile species, by skewing the population sex ratio to one that favors females. However, the ovaries of E2SD-female caimans differ from those of TSD-females. In crocodilians, the external genitalia (i.e. clitero-penis structure or phallus) are sexually dimorphic and hormone-sensitive. Despite some morphological descriptions aimed to facilitate sexing, we found no available data on the C. latirostris phallus histoarchitecture or hormone dependence. Thus, the aims of this study were: (1) to establish the temporal growth pattern of the phallus in male and female caimans; (2) to evaluate histo morphological features and the expression of estrogen receptor alpha (ERalpha) and androgen receptor (AR) in the phallus of male and female pre-pubertal juvenile caimans; and (3) to determine whether the phallus of TSD-females differs from the phallus of E2SD-females. Our results demonstrated sexually dimorphic differences in the size and growth dynamics of the caiman external genitalia, similarities in the shape and spatial distribution of general histo-morphological compartments, and sexually dimorphic differences in innervation, smooth muscle fiber distribution, collagen organization, and ERalpha and AR expressions. The external genitalia of E2SD-females differed from that of TSD-females in many histological features and in the expression of ERalpha and AR, resembling patterns described in males. Our results alert on the effects of estrogen agonist exposure during TSW and suggest that caution must be taken regarding the use of E2SD as a procedure for wildlife population management. PMID- 30292703 TI - Diversity of aminoglycoside modifying enzymes and 16S rRNA methylases in Acinetobacter baumannii and Acinetobacter nosocomialis species in Iran; wide distribution of aadA1 and armA. AB - PURPOSE: Acinetobacter baumannii-calcoaceticus complex (ABC) make a great burden on health-care systems due to hospital-acquired infections and antibacterial resistance. Aminoglycoside in combination with other antibacterials used as treatment options. However, ABC species overcome this class of antibacterials in different ways. This study provides a comprehensive report on the distribution of aminoglycoside modifying enzymes (AMEs) and 16S rRNA methylase in Acinetobacter baumannii and Acinetobacter nosocomialis isolated from various provinces in Iran. METHODS: During six month of study, from eight referral centers in seven provinces across the country, Iran, 178 A. baumannii and 43 A. nosocomialis isolates were collected. The minimum inhibitory concentration of amikacin, gentamicin, netilmicin, kanamycin and tobramycin were measured by microbroth dilution method. AMEs and 16S rRNA methylase variants were sought by PCR. RESULTS: High rates of resistance were seen in all centers. MIC50 and MIC90 for all A. baumannii and A. nosocomialis isolates from different centers were > 512 mg/L. The most frequent AME was ant(3")-Ia (aadA1) in both of A. baumannii (74.1%) and A. nosocomialis (86%). armA was detected in A. baumannii and A. nosocomialis at the frequency of 41.6% and 67.4%, respectively. rmtA, B, C, D, aac(3)-Ia (aacC1) and aac(6')-Im were not detected, neither in A. baumannii nor A. nosocomialis. Moreover, aac(6')-Ih was only found in A. baumannii isolates. The distribution of some of the ARGs was limited to a definite center. CONCLUSION: The overall high-level carriage of ARGs in Acinetobacter species may limited usage of this class of antibacterials as a treatment option.

PMID- 30292704 TI - Combined Experimental and System-Level Analyses Reveal the Complex Regulatory Network of miR-124 during Human Neurogenesis. AB - Non-coding RNAs regulate many biological processes including neurogenesis. The brain-enriched miR-124 has been assigned as a key player of neuronal differentiation via its complex but little understood regulation of thousands of annotated targets. To systematically chart its regulatory functions, we used CRISPR/Cas9 gene editing to disrupt all six miR-124 alleles in human induced pluripotent stem cells. Upon neuronal induction, miR-124-deleted cells underwent neurogenesis and became functional neurons, albeit with altered morphology and neurotransmitter specification. Using RNA-induced-silencing-complex precipitation, we identified 98 high-confidence miR-124 targets, of which some directly led to decreased viability. By performing advanced transcription-factor network analysis, we identified indirect miR-124 effects on apoptosis, neuronal subtype differentiation, and the regulation of previously uncharacterized zinc finger transcription factors. Our data emphasize the need for combined experimental- and system-level analyses to comprehensively disentangle and reveal miRNA functions, including their involvement in the neurogenesis of diverse neuronal cell types found in the human brain. PMID- 30292705 TI - Geometry-Dependent Arrhythmias in Electrically Excitable Tissues. AB - Little is known about how individual cells sense the macroscopic geometry of their tissue environment. Here, we explore whether long-range electrical signaling can convey information on tissue geometry to individual cells. First, we studied an engineered electrically excitable cell line. Cells grown in patterned islands of different shapes showed remarkably diverse firing patterns under otherwise identical conditions, including regular spiking, period-doubling alternans, and arrhythmic firing. A Hodgkin-Huxley numerical model quantitatively reproduced these effects, showing how the macroscopic geometry affected the single-cell electrophysiology via the influence of gap junction-mediated electrical coupling. Qualitatively similar geometry-dependent dynamics were observed in human induced pluripotent stem cell (iPSC)-derived cardiomyocytes. The cardiac results urge caution in translating observations of arrhythmia in vitro to predictions in vivo, where the tissue geometry is very different. We study how to extrapolate electrophysiological measurements between tissues with different geometries and different gap junction couplings. PMID- 30292707 TI - Carbon/Nitrogen Metabolic Balance: Lessons from Cyanobacteria. AB - Carbon and nitrogen are the two most abundant nutrient elements for all living organisms, and their metabolism is tightly coupled. What are the signaling mechanisms that cells use to sense and control the carbon/nitrogen (C/N) metabolic balance following environmental changes? Based on studies in cyanobacteria, it was found that 2-phosphoglycolate derived from the oxygenase activity of Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) and 2 oxoglutarate from the Krebs cycle act as the carbon- and nitrogen-starvation signals, respectively, and their concentration ratio likely reflects the status of the C/N metabolic balance. We will present and discuss the regulatory principles underlying the signaling mechanisms, which are likely to be conserved in other photosynthetic organisms. These concepts may also contribute to developments in the field of biofuel engineering or improvements in crop productivity. PMID- 30292708 TI - What to do if A + B doesn't work. AB - The majority of newborn resuscitations require very little beyond simple airway management and assisted ventilation. If cardiovascular collapse is serious enough to warrant additional support, resuscitation algorithms recommend moving to chest compressions and then on to medications and possibly volume replacement if vital signs remain marginal or absent. The evidence base upon which this part of the neonatal resuscitation algorithm is structured is sparse. Chest compressions and medications are rare interventions that do not lend themselves easily to clinical trials. Slowly but surely, however, the genesis of an empirical evidence base for this part of the algorithm is beginning to appear. PMID- 30292709 TI - Genetic predisposition to necrotizing enterocolitis in premature infants: Current knowledge, challenges, and future directions. AB - The role of genetics in the pathogenesis of necrotizing enterocolitis (NEC) was initially informed by epidemiological data indicating differences in prevalence among different ethnic groups as well as concordance in twins. These early observations, together with major advances in genomic research, paved the way for studies that begin to reveal the contribution of genetics to NEC. Using the candidate gene or pathway approach, several potential pathogenic variants for NEC in premature infants have already been identified. More recently, genome-wide association studies and exome-sequencing based studies for NEC have been reported. These advances, however, are tempered by the lack of adequately powered replication cohorts to validate the accuracy of these discoveries. Despite many challenges, genetic research in NEC is expected to increase, providing new insights into its pathogenesis and bringing the promise of personalized care closer to reality. In this review we provide a summary of genetic studies in NEC along with defining the challenges and possible future approaches.

AB - Radial head arthroplasty was introduced in 1941 and the literature supports satisfactory overall midterm patient outcomes and acceptable complication profiles with several models. There are several previously described mechanisms by which radial head complications typically occur. We present the case of a rarely described mechanism of radial head implant failure: elbow synovitis and pain from partial dissociation and metallosis in an adjustably aligned, modular, monopolar, mixed metal, press-fit radial head arthroplasty. PMID- 30292712 TI - Distal Dorsal Dimelia: A Disturbance of Dorsal-Ventral Digit Development. AB - PURPOSE: Congenital palmar nail (distal dorsal dimelia [dDD]) of the hand is a rare malformation most commonly affecting the little finger. The purpose of this report was to review the features and associations of this rare disorder and discuss the suspected underlying etiology in light of our current understanding of developmental biology. METHODS: In this retrospective cohort study from 3 practices, we describe our collective experience and review the reported literature on this disorder both as an isolated condition and in conjunction with other anomalies. RESULTS: We examined 15 fingers with dDD, 5 of which involved little fingers. We also found dDD in 6 cases with radial polydactyly (preaxial polydactyl type II [PPD2]) and in 1 case of cleft hand involving digits adjacent to the clefted web space (the index and middle fingers). Cases of little finger dDD were also associated with prominent clefting of the adjacent web space in 4 of 5 cases. All cases had stiffness of the interphalangeal joints and loss of palmar creases consistent with dorsalization of the palmar aspect of the digit. When combined with 63 fingers reported in the literature with dDD, 3 patterns were evident. The most common form occurred in little fingers (n = 50; 64%; dDDu). The next most common form was reported in association with cleft hands (n = 16; 21%; dDDc). Radial digits in association with either radial polydactyly (PPD2) or radial longitudinal deficiency were also susceptible to dDD (n = 12; 15%; dDDr). CONCLUSIONS: Congenital dDD is a disturbance of terminal dorsal ventral digit patterning. The distribution of this condition with little fingers, clefting, and altered radial digit formation (PPD2 or radial longitudinal deficiency), as well as recent genetic and animal studies, suggests that dDD and altered dorsal-ventral patterning are linked to abnormal apical ectodermal ridge boundary formation. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic IV. PMID- 30292713 TI - Multiple Stab Incisions and Evacuation Technique for Contrast Extravasation of the Hand and Forearm. AB - Extravasation of intravenous contrast agents in the hand and forearm during computed tomography scanning is rising with the use of automated pressure injectors. The main concern in such a situation is progression to acute compartment syndrome and necrosis of the overlying skin. Management has been mainly nonsurgical comprising upper limb elevation and orthosis, with surgical techniques such as liposuction and saline evacuation mainly used for large volume (>50 mL) extravasations. We have developed a technique of multiple stab incisions and drainage for the treatment of contrast extravasations. PMID- 30292715 TI - Thumb Amputations in Children: Classification and Reconstruction by Microsurgical Toe Transfers. AB - PURPOSE: Traumatic amputations of the thumb are rare in children compared with adults, but hand surgeons remain reticent to consider microsurgical reconstruction with toe-to-thumb transfers. This study reports the functional outcomes and complications of children with traumatic thumb amputations who underwent toe-to-thumb reconstruction. METHODS: A retrospective review of children who sustained thumb amputations and whose parents elected for their child to undergo reconstruction by toe-to-thumb transfer was performed. Details of the level of thumb amputation, whether other fingers were also amputated, which toe was transferred on which vascular pedicle, survival of the transfer, and complications, were collected. Opposition, sensation, and growth of the toe to-thumb transfers was measured. Functional and psychosocial outcomes were evaluated by both the parents and the older children using the Pediatric Outcomes Data Collection Instrument questionnaire. RESULTS: Twenty-one thumb amputations in 19 children between the ages of 2 and 17 years were referred for secondary reconstruction. Ten were isolated thumb amputations and 11 were combined thumb and multiple finger amputations. Two children had bilateral thumb amputations. Twenty-one toe-to-thumb transfers were performed: 14 second toe transfers and 7 great toe transfers (3 great toe and 2 trimmed and 2 Morrison wraparound variations). There were no immediate postoperative reexplorations of the microsurgical anastomoses and all toe transfers survived completely. All children regained pinch and grasp function and sensation. There were no gait problems in the donor feet. CONCLUSIONS: Microsurgical toe-to-thumb transfers should be offered as an alternative option to the traditional techniques of distraction lengthening and pollicization, for posttraumatic thumb reconstruction in children for any level of amputation from just distal to the carpometacarpal joint to the interphalangeal joint. Toe-to-thumb transfer provides length, opposition, and sensation without disturbing ambulation and is associated with excellent psychosocial outcomes as evaluated by both parents and older children. TYPE OF STUDY/LEVEL OF EVIDENCE: IV. PMID- 30292714 TI - Factors Accounting for Variation in the Biomechanical Properties of Flexor Tendon Repairs. AB - PURPOSE: To investigate factors that cause variation in the mechanical properties of flexor tendon repairs. METHODS: One surgeon repaired 50 homogeneous absorbent sticks and 40 porcine flexor tendons with a simple loop, an Adelaide repair, a peripheral over-and-over repair, or a combination of the latter 2 repairs. Ten hand surgeons repaired 1 porcine flexor tendon with the combined Adelaide core and over-and-over peripheral repair. We loaded the samples statically until failure and calculated the variations caused by the testing process, tendon substance, and surgical performance in terms of yield and ultimate load. RESULTS: Tendon material and surgical performance both caused about half of the variation in the yield load of the combined repair. Surgical performance caused all variations observed in the ultimate load of the combined, peripheral-only, and core repairs. The effect of the tendon material was negligible in ultimate load. The intersurgeon variation was present only in yield load, and it represented one tenth of the total variation. CONCLUSIONS: The effect of tendon substance on variation of the ultimate load is minimal. In yield load, both tendon and surgical performance are responsible for the variation. CLINICAL RELEVANCE: In clinical realm, variation caused by testing is not present, but intersurgeon variation may cause additional variation in yield load. A hand surgeon cannot change the variation due to tendon properties, but with a more meticulous surgical technique, the variation related to the surgical performance can probably be diminished. PMID- 30292716 TI - Contact Mechanics of Anatomic Radial Head Prosthesis: Comparison Between Native Radial Head and Anatomic Radial Head Prostheses in the Dynamic Mode. AB - PURPOSE: The biomechanical characteristics of anatomic radial head prostheses have not been completely investigated. We compared and analyzed the contact kinematic characteristics of the native radial head and radial head prostheses replicating the native head contour, using a real-time flexion simulation model. METHODS: Ten fresh-frozen cadavers were used in this pilot study. A simulating dynamic motion mode from 0 degrees to 130 degrees of elbow flexion was applied. Radiocapitellar contact pressure and area were measured using a real-time digitized pressure sensor. Further, contact area and pressure curves were obtained during flexion, using a motion-tracking device. RESULTS: The mean contact area, mean contact pressure, and peak contact pressure of the native radial head and radial head prosthesis were 39 mm2, 0.0078 kgf/mm2, 0.0123 kgf/mm2, and 33 mm2, 0.0093 kgf/dm2, 0.0148 kgf/mm2, respectively. The contact area and pressure curves were parabolic nonlinear for the radial head prosthesis and more linear for the native radial head. CONCLUSIONS: The radial head prosthesis mimics the mechanics of the native radial head in terms of mean contact area, mean contact pressure, and peak contact pressure; however, different patterns of contact pressure and area curves during elbow flexion extension were observed. CLINICAL RELEVANCE: We found that the biomechanics of the anatomic radial head prostheses used in the study were similar to those of the native radial head. PMID- 30292717 TI - Anatomy, Etiology, and Management of Scapular Winging. AB - Scapular winging is a painful and debilitating condition. The composite scapular motion of rotation, abduction, and tilting is necessary for proper shoulder function. Weakness or loss of scapular mechanics can lead to difficulties with elevation of the arm and lifting objects. The most common causes reported in the literature for scapular winging are dysfunction of the serratus anterior from long thoracic nerve injury causing medial winging or dysfunction of the trapezius from spinal accessory nerve injury causing lateral winging. Most reviews and teaching focus on these etiologies. However, acute traumatic tears of the serratus anterior, trapezius, and rhomboids off of the scapula are important and under-recognized causes of scapular winging and dysfunction. This article will review the relevant anatomy, etiology, clinical evaluation, diagnostic testing, and treatment of scapular winging. It will also discuss the differences in diagnosis and management between scapular winging arising from neurogenic causes and traumatic muscular detachment. PMID- 30292718 TI - H-reflex disinhibition by lumbar muscle inflammation in a mouse model of spinal cord injury. AB - Inflammation is a common comorbidity in patients with traumatic spinal cord injury (SCI). Recent reports indicate that inflammation hinders functional recovery in animal models of SCI. However, the spinal mechanisms underlying this alteration are currently unknown. Considering that spinal plasticity is a therapeutic target in patients and animal models of SCI, these mechanisms remain to be clarified. Using injections of complete Freund's adjuvant (CFA) in lumbar muscles as a model of persistent inflammation, the objective of this study was to assess the impact of inflammation on spinal reflex excitability after a complete midthoracic spinal transection in mice. To this end, the excitability of spinal reflexes was examined by measuring H-reflex frequency-dependent depression (FDD) on days 7, 14 and 28 following a complete spinal transection. H-reflex parameters were compared between spinal mice with CFA and control spinal mice. On day 7, lumbar muscle inflammation disinhibited the H-reflex, reflected by an attenuation of H-reflex FDD (p < 0.01), although this effect did not persist later on, either on day 14 or day 28. These results indicate that lumbar muscle inflammation alters spinal reflex excitability transiently in spinal mice. Considering that changes in spinal reflex excitability are associated with poor functional recovery after SCI, this implies that inflammation should be treated effectively to promote optimal recovery following SCI. PMID- 30292719 TI - A preliminary examination of the relation between neural sensitivity to reward and history of alcohol use disorder among adults with internalizing psychopathologies. AB - Decreased reward responsiveness, as demonstrated utilizing the event-related potential (ERP) component the reward positivity (RewP), is an established correlate of internalizing psychopathologies (IPs), such as depressive and anxiety disorders. Although IPs are highly comorbid with alcohol use disorders (AUDs) and despite evidence that AUDs are also characterized by aberrant reward processing styles, no studies have examined how AUD history impacts the RewP among adults with IPs. The current preliminary study sought to examine this question in a sample of 65 adults with 1) current IPs (i.e., depression, social anxiety, and/or generalized anxiety, 2) current IPs with a history of an AUD (IP + Past AUD), and 3) no history of a DSM-IV disorder. Participants completed a guessing reward task while electroencephalogram (EEG) was recorded. Results indicated that participants in the IP group exhibited a more attenuated RewP relative to IP + Past AUD and healthy control individuals. Findings from this study highlight the importance of examining diagnostic subgroups among adults with anxiety and depressive disorders, and suggest that a history of AUD may enhance reward reactivity at the neural level in individuals with IPs. PMID- 30292720 TI - Chronic antidepressant-like effect of EMD386088, a partial 5-HT6 receptor agonist, in olfactory bulbectomy model may be connected with BDNF and/or CREB signalling pathway. AB - BACKGROUND: The removal of the olfactory bulbs has been attributed to behavioral changes and neuroplasticity manifesting themselves among others like increases in brain neurotrophin expression and neurogenesis. Earlier data presented that EMD386088, a 5-HT6 receptor partial agonist, exerts antidepressant-like properties after chronic administration in olfactory bulbectomy (OB) model as was it compared with amitriptyline (AMI). The aim of this study was to compare acute and chronic biochemical effects of EMD386088, administered in its antidepressant active (2.5 mg/kg) and non-active (1.25 mg/kg) doses, found in the open field test in OB rats, with those of AMI (10 mg/kg).The levels of 5-HT6 receptor protein and selected neurotrophins in prefrontal cortex (PFC) and hippocampus (Hp) of rats have been examined. METHODS: 5-HT6 receptor protein and selected neurotrophins: brain-derived neurotrophic factor (BDNF), cAMP-response element binding protein (CREB), the product of the immediate early gene c-fos (cFos) protein levels were assessed using a Western blot analysis in PFC and Hp of bulbectomized rats after acute or chronic (14-day) EMD386088 or AMI intraperitoneal (ip) treatment. RESULTS: The acute treatment with EMD386088 caused significant increases in CREB and BDNF protein levels in PFC, and an increase in BDNF in Hp of OB rats, while AMI injection decreased CREB and did not change BDNF levels. After the chronic administration of EMD386088, the increasing levels of BDNF and CREB were still observed in PFC and Hp. CONCLUSIONS: The antidepressant-like effect of EMD386088 may be associated with the neuroplasticity activation in PFC and Hp in rats. PMID- 30292721 TI - Involvement of transcription-coupled repair factor Mfd and DNA helicase UvrD in mutational processes in Pseudomonas putida. AB - Stalled RNA polymerases (RNAPs) pose an obstacle for the replicating complexes, which could lead to transcription-replication conflicts and result in genetic instability. Stalled RNAPs and DNA lesions blocking RNAP elongation are removed by transcription-coupled repair (TCR), the process which in bacteria is mediated by TCR factor Mfd and helicase UvrD. Although the mechanism of TCR has been extensively studied, its role in mutagenesis is still obscure. In the current study we have investigated the role of Mfd and UvrD in mutational processes in soil bacterium Pseudomonas putida. Our results revealed that UvrD helicase is essential to prevent the emergence of mutations, as the loss of uvrD resulted in elevated mutant frequency both in exponential- and stationary-phase bacterial cultures. UvrD was also found to be necessary to survive DNA damage, but NER or MMR pathways are not completely abolished in UvrD-deficient P. putida. Mfd deficiency had a moderate impact on surviving DNA damage and did not influence the frequency of mutations occurred in exponentially growing bacteria. However, the absence of Mfd caused approximately a two-fold decline in stationary-phase mutant frequency compared to the P. putida wild-type strain and suppressed the elevated mutant frequency observed in the DeltauvrD strain. Remarkably, the Mfd deficient strain also formed less UV-induced mutants. These results suggest that in P. putida the Mfd-mediated TCR could be associated with UV- and stationary phase mutagenesis. PMID- 30292722 TI - Effects of beta-subunit on gating of a potassium ion channel: Molecular simulations of cardiac IKs activation. AB - Dynamic conformational changes of ion channel proteins during activation gating determine their function as carriers of current. The relationship between these molecular movements and channel function over the physiological timescale of the action potential (AP) has not been fully established due to limitations of existing techniques. We constructed a library of possible cardiac IKs protein conformations and applied a combination of protein segmentation and energy linearization to study this relationship computationally. Simulations reproduced the effects of the beta-subunit (KCNE1) on the alpha-subunit (KCNQ1) dynamics and function, observed in experiments. Mechanistically, KCNE1 increased the probability of "visiting" conducting pore conformations on activation trajectories, thereby increasing IKs current. KCNE1 slowed IKs activation by impeding the voltage sensor (VS) movement and reducing its coupling to pore opening. Conformational changes along activation trajectories determined that the S4-S5 linker (S4S5L) plays an important role in these modulatory effects by KCNE1. Integration of these molecular structure-based IKs dynamics into a model of human cardiac ventricular myocyte, revealed that KCNQ1-KCNE1 interaction is essential for normal AP repolarization. PMID- 30292723 TI - Curcumin protects against diabetic cardiomyopathy by promoting autophagy and alleviating apoptosis. AB - The effects of curcumin on regulating cardiac apoptosis and autophagy were analyzed in diabetic models both in vivo and in vitro. In vivo, experimental diabetes was induced in mice by low-dose STZ injection combined with a high-fat diet. In vitro, cultured H9c2 cardiomyoblasts were exposed to high d-glucose concentrations combined with palmitate. Our results showed that apoptosis was increased and autophagy was suppressed in the hearts of diabetic mice, which was ameliorated by curcumin treatment, ultimately improving cardiac function. Moreover, the inhibition of autophagy exacerbated apoptotic death in cardiac cells under diabetic condition. Curcumin activated AMPK and JNK1, which phosphorylated Bcl-2 and Bim and subsequently disrupted their interactions with Beclin1, thereby promoting autophagy and alleviating apoptosis respectively. In addition, AMPK-mediated inhibition of mTORC1 pathway likely played a role in regulating autophagy by curcumin under diabetic condition. Our study suggests that curcumin protects against diabetic cardiomyopathy by modulating the crosstalk between autophagic and apoptotic machinery. Modulation of autophagy may be an effective strategy for the treatment of cardiovascular diseases associated with diabetes. PMID- 30292724 TI - Benefits of low vision aids to reading accessibility. AB - The Reading Accessibility Index (ACC) has been proposed as a single-value reading parameter that can capture information on both reading speed and print sizes that can be read. It is defined as the average reading speed across a relevant range of print sizes (1.3-0.4logMAR), normalised by typical young-adult reading speed of 200 wpm, and with values typically in the range of 0-1. This study determines the impact of low vision aids (LVAs) on reading by evaluating ACC values for visually impaired observers reading both without and with an optical LVA. A secondary analysis of previously published data obtained from 100 visually impaired observers attending low vision assessments was undertaken. Observers had mixed causes of visual impairment but predominantly macular degeneration. All used an LVA for reading, with 88% using it 'often' or 'very often'. MNREAD reading parameters, including ACC, were determined both for reading without an LVA (clinical function) and with the LVA habitually used for reading (aided function). There was a significant improvement in ACC from clinical (0.31) to aided conditions (0.47). Average improvement in ACC with an LVA was 0.16, but the benefits of LVAs in terms of improvement in ACC could not be predicted from clinical visual function. Even with an LVA reading accessibility is, on average, markedly reduced from normal levels. The ACC is a potentially valuable outcome measure for reading rehabilitation interventions. PMID- 30292725 TI - A comparison of tests for quantifying sensory eye dominance. AB - Clinicians rely heavily on stereoacuity to measure binocular visual function, but stereo-vision represents only one aspect of binocularity. Lab-based tests of sensory eye dominance (SED) are commonplace, but have not been translated to wider clinical practice. Here we compare several methods of quantifying SED in a format suitable for clinical use. We tested 30 participants with ostensibly normal vision on eight tests. Seven tests (#1-7) were designed to quantify SED in the form of an interocular balance-point (BP). In tests #1-6, we estimated a contrast-BP, the interocular difference in contrast required for observers to be equally likely to base their judgement on either eye, whereas in test #7 we measured binocular rivalry (interocular ratio of sensory dominance duration). We compare test-retest reliability (intra-observer consistency) and test-validity (inter-observer discriminatory power) and compare BP to stereoacuity (test #8). The test that best preserved inter-observer differences in contrast balance while maintaining good test-retest reliability was a polarity judgement using superimposed opposite-contrast polarity same-identity optotypes. A reliable and valid measure of SED can be obtained rapidly (20 trials) using a simple contrast polarity judgement. Tests that use polarity-rivalrous stimuli elicit more reliable judgments than those that do not. SIGNIFICANCE STATEMENT: Although sensory eye dominance is central to understanding normal and disordered binocular vision, there is currently no consensus as to the best way to measure it. Here we compare several candidate measures of sensory eye dominance and conclude that a reliable measure of SED can be achieved rapidly using a judgement of stimulus contrast-polarity.

AB - BACKGROUND: Cannabis consumption is widespread across the world, and the co occurrence of cannabis use and alcohol consumption is common. The study of background noise - resting-state neural activity, in the absence of stimulation - is an approach that could enable the neurotoxicity of these substances to be explored. Preliminary results have shown that delta-9-tetrahydrocannabinol (Delta9-THC) causes an increase in neural noise in the brain. Neurons in the brain and the retina share a neurotransmission system and have similar anatomical and functional properties. Retinal function, evaluated using an electroretinogram (ERG), may therefore reflect central neurochemistry. This study analyses retinal background noise in a population of regular co-occurrent cannabis and alcohol consumers. METHODS: We recorded the flash ERGs of 26 healthy controls and 45 regular cannabis consumers, separated into two groups based on their alcohol consumption: less than or equal to 4 glasses per week (CU <= 4) or strictly >4 glasses per week (CU >4). In order to extract the background noise, the Fourier transform of the pseudo-periodic and sinusoidal signals of the 3.0 flicker response sequence was calculated. This sequence represents the vertical transmission of the signal from cones to bipolar cells. The magnitude of the background noise is defined as the average of the magnitudes of the two neighbouring harmonics: harmonic -1 (low frequency noise) and harmonic +1 (high frequency noise). RESULTS: The magnitude of harmonic -1 was significantly increased between the groups CU > 4 (6.78 (+/-1.24)) and CU <= 4 (5.69 (+/-1.80)) among regular users of cannabis and alcohol. A significant increase in the average magnitude of the two harmonics was found between the groups CU > 4 (5.12 (+/-0.92)) and CU <= 4 (4.36 (+/-1.14)). No significant difference was observed with regard to the magnitude of the harmonic +1. CONCLUSIONS: The increase in background noise may reflect the neurotoxicity of cannabis, potentiated by alcohol consumption, on retinal neurons dynamic. This neural disruption of the response generated by retinal stimulation may be attributable to altered neurotransmitter release.

AB - The discipline of affective neuroscience is concerned with the neural bases of emotion and mood. The past decades have witnessed an explosion of research in affective neuroscience, increasing our knowledge of the brain areas involved in fear and anxiety. Besides the brain areas that are classically associated with emotional reactivity, accumulating evidence indicates that both the vestibular and cerebellar systems are involved not only in motor coordination but also influence both cognition and emotional regulation in humans and animal models. The cerebellar and the vestibular systems show the reciprocal connection with a myriad of anxiety and fear brain areas. Perception anticipation and action are also major centers of interest in cognitive neurosciences. The cerebellum is crucial for the development of an internal model of action and the vestibular system is relevant for perception, gravity-related balance, navigation and motor decision-making. Furthermore, there are close relationships between these two systems. With regard to the cooperation between the vestibular and cerebellar systems for the elaboration and the coordination of emotional cognitive and visceral responses, we propose that altering the function of one of the systems could provoke internal model disturbances and, as a result, anxiety disorders followed potentially with depressive states. PMID- 30292731 TI - Sleep Disorders. AB - Sleep disorders are frequent and can have serious consequences on patients' health and quality of life. While some sleep disorders are more challenging to treat, most can be easily managed with adequate interventions. We review the main diagnostic features of 6 major sleep disorders (insomnia, circadian rhythm disorders, sleep-disordered breathing, hypersomnia/narcolepsy, parasomnias, and restless legs syndrome/periodic limb movement disorder) to aid medical practitioners in screening and treating sleep disorders as part of clinical practice. PMID- 30292732 TI - Predictors of simulated driving performance in Huntington's disease. AB - BACKGROUND: As the disease progresses, patients with Huntington's disease (HD), an inherited neurodegenerative disorder, become less independent in their daily life activities and have to consider if they can still drive a car. For most patients, the decision to quit driving is difficult and affects their independence and social activities. OBJECTIVE: To investigate if cognitive, motor, or psychiatric symptoms can predict driving performance in HD gene carriers using a simulator situation. METHODS: Twenty-nine controls, 28 premanifest HD, and 30 manifest HD participated in this observational, cross sectional study and underwent neuropsychological, motor, and psychiatric evaluations. All participants drove a motorway scenario in a driving simulator to evaluate driving performance. Group differences were analyzed using Analysis of Covariance and stepwise forward linear regression analysis was used to investigate which clinical assessments were predictors of driving simulator outcomes. RESULTS: Manifest HD drove slower and had less vehicle control in the driving simulator compared to controls and premanifest HD. They also performed worse on all clinical assessments compared to controls. Postural sway and slower speed of information processing were predictors of the driving simulator outcome measures. Psychiatric symptoms were unrelated to simulated driving. There were no significant differences between premanifest HD and controls. CONCLUSIONS: Increased postural sway and slower speed of processing are predictive of driving simulator performance in manifest HD. Worse performance on these clinical tasks might be useful as a first screening and could assist clinicians in their referral for an official on-road driving test.

AB - INTRODUCTION: Patients with Gilles de la Tourette syndrome (GTS) experience reduced function and impaired quality of life. The current medical treatments for this syndrome can cause significant side effects and offer partial symptomatic relief. In a few small trials medical cannabis (MC) has been suggested to offer symptomatic relief with a relatively benign side effect profile. We conducted a real-life assessment of clinical benefit and adverse effects of chronic MC treatment among patients with GTS. METHODS: GTS patients treated with MC were interviewed via phone regarding treatment efficacy and side effect profile from chronic MC consumption. Global efficacy was rated on a Likert scale of 1-5 and side effects of treatment were recorded. RESULTS: Forty-Two GTS patients (33 males, mean age 34.5) were interviewed for this study. The total global impression score of efficacy was 3.85 out of a total 5 possible points. Patients reported during the free discussion part of the interview about reduction in tic severity, better sleep and improved mood as positive effects of MC. Thirty-eight patients reported any kind of benefit from treatment while 10 patients with more than one year of consumption elected to stop treatment with MC for various reasons including severe side effects as psychosis in one patient. CONCLUSION: MC seems to hold promise in the treatment of GTS as it demonstrated high subjective satisfaction by most patients however not without side effects and should be further investigated as a treatment option for this syndrome.

AB - INTRODUCTION: In Parkinson's disease, dyskinesias result from disease progression and chronic levodopa therapy. Using Unified Dyskinesia Rating Scale (UDysRS) data pooled from two pivotal trials of ADS-5102 (amantadine) extended-release capsules in dyskinetic patients, we assessed the impact of dyskinesia on activities of daily living (ADLs), and the effects of ADS-5102 versus placebo. METHODS: Patients had troublesome dyskinesia (>=1 h/day) and at least mild functional impact of dyskinesia per Movement Disorder Society Unified Parkinson's Disease Rating Scale, Part IV, item 4.2. UDysRS Parts 1B, 3, and 4 scores at baseline were summarized descriptively. Twelve-week changes in score distributions and total scores were tested for significant differences between treatments. RESULTS: Among 196 patients, the majority (63%-73%) characterized their dyskinesia at baseline as having at least a mild impact on walking and balance; public and social settings; exciting or emotional settings; doing hobbies and other activities; handwriting; and dressing (six of ten ADLs in UDysRS Part 1B). By clinician ratings (in Parts 3 and 4), greatest impairment was most often observed in the trunk (62% of patients) and occurred most often for the ADL of dressing (64% had at least moderate impairment). ADS-5102 significantly reduced the patient-rated impact of dyskinesia on six of ten ADLs in Part 1B, the clinician rated intensity of dyskinesia in all seven body regions assessed in Part 3, and the clinician-rated disability during three of four ADL tasks assessed in Part 4. Improvements in Parts 1B, 3, and 4 total scores were also statistically significant. CONCLUSION: Dyskinesia can impair multiple tasks of daily living. Further studies may help characterize its underreported impact. By several measures, ADS-5102 treatment was associated with significant improvement of dyskinesias. PMID- 30292735 TI - A punch in the gut - Intestinal inflammation links environmental factors to neurodegeneration in Parkinson's disease. AB - Parkinson's disease (PD) is an etiologically heterogeneous disorder. Experimental, clinical and epidemiological data suggest that intestinal inflammation contributes to the pathogenesis of PD. This article reviews recent literature on gut microbiota and intestinal inflammation in PD. We propose that intestinal inflammation links environmental factors (e.g. an altered gut microbiota composition) to neurodegeneration in (genetically susceptible) PD patients. In addition, there is an epidemiological and genetic overlap between PD and inflammatory bowel disease. This overlap provides an opportunity to develop new treatment strategies for at least a subgroup of PD patients. PMID- 30292736 TI - Health-Related Quality of Life of Patients With Multiple Myeloma Treated in Routine Clinical Practice in France. AB - INTRODUCTION: New therapies for multiple myeloma (MM) have improved life expectancy, but health-related quality of life (HRQoL) data from patients with MM in the real-world setting are lacking. This study, conducted in France, explored the associations between treatment outcomes and HRQoL in patients with MM. PATIENTS AND METHODS: This observational, cross-sectional, multicenter study enrolled patients (>= 18 years old) with symptomatic MM who had consulted a physician at least once between February and March 2016. HRQoL was assessed using the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life questionnaire (QLQ-C30) and the Quality of Life Multiple Myeloma module (QLQ-MY20). RESULTS: In total, 445 patients were included in the study; 402 (90%) completed the EORTC QLQ-C30 and QLQ-MY20 questionnaires. HRQoL decreased significantly with treatment line. Patients in the first treatment-free interval had relatively high scores. At later lines, patients receiving active treatment had better scores than those whose treatment had ended. High EORTC QLQ C30 global health status scores were associated with good treatment response, few adverse events, and long duration of treatment, and were strongly influenced by the Eastern Cooperative Oncology Group performance status. Global health status scores correlated well with the 4 items of the QLQ-MY20 (future perspective, 0.46; body image, 0.41; disease symptoms, -0.57; side effects of treatment, 0.53). CONCLUSION: Effective treatment options in MM can help maintain HRQoL by influencing treatment response levels and delaying disease progression. PMID- 30292737 TI - Interim Functional Imaging Is an Independent Predictor of Progression-free Survival in Advanced Classical Hodgkin Lymphoma - A Real-world Analysis. AB - BACKGROUND: Response-adapted therapy in advanced classical Hodgkin lymphoma (cHL) using interim functional imaging (IFI) is under active investigation. PATIENTS AND METHODS: We retrospectively examined patients with advanced cHL receiving 2 front-line regimens stratified by IFI results at our institution. Time to endpoint analysis was estimated using the method of Kaplan-Meier with log ranks. Cox regression modeling was computed for multivariable analysis. RESULTS: A total of 124 patients with advanced cHL with a median follow up of 40.9 months were included. A total of 84 (67.7%) received ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine), whereas the remaining 40 (32.3%) received ABVD/eBEACOPP (escalated bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone). A positive IFI was seen in 36 (29%) patients. The corresponding 3-year progression free survival (PFS) stratified by IFI was 81.7% (95% confidence interval [CI], 70.1%-88.8%) versus 48.3% (95% CI, 30.4%-64.1%) (P < .0001) for patients with negative or positive scan, respectively. Escalation to eBEACOPP from ABVD following a positive IFI resulted in a significantly higher 3-year PFS at 58.7% (95% CI, 0.3-0.79) versus 39.7% (95% CI, 0.18-0.61) respectively (P = .00015). Overall survival (OS) was similar across the groups (P = .44) irrespective of therapy received. At multivariable analysis, IFI was the only predictor of PFS with a hazard ratio of 4.6 (95% CI, 1.9-10.8; P = .0008) whereas therapy escalation had a hazard ratio of 0.66 (95% CI, 0.14-3.4; P = .62). CONCLUSION: IFI is an independent predictor of PFS in advanced cHL and can guide therapeutic decisions in the real world. Given the inferior outcome seen in patients with a positive IFI, novel approaches of therapy are warranted.

PMID- 30292739 TI - The beach chair position for shoulder surgery in intravenous general anesthesia and controlled hypotension: Impact on cerebral oxygenation, cerebral blood flow and neurobehavioral outcome. AB - STUDY OBJECTIVES: The aim of this study was to assess the impact of intravenous general anesthesia and controlled hypotension on cerebral saturation (rScO2), cerebral blood flow measured as middle cerebral artery blood flow velocity (Vmax MCA) and neurobehavioral outcome in patients scheduled for shoulder surgery in beach chair position. DESIGN: Prospective, assessor-blinded observational study. SETTING: University hospital, shoulder surgery operating room. PATIENTS: Forty ASA I-II patients scheduled for shoulder surgery in beach chair position and controlled hypotension. INTERVENTIONS: Neurological and neurobehavioral tests were performed prior and the day after surgery. The baseline data for near infrared spectroscopy, bispectral index, cerebral blood flow, PaCO2 and invasive blood pressure (radial artery) were taken prior anesthesia and after anesthesia induction, after beach chair positioning and all 20 min after surgery start until discharge of the patient. MEASUREMENTS: Neurological and neurobehavioral tests, cerebral saturation (rScO2) using near-infrared spectroscopy, BIS, cerebral blood flow using Doppler of the middle cerebral artery (Vmax MCA), PaCO2 and invasive blood pressure assessed at heart and at the external acoustic meatus level. MAIN RESULTS: The incidence of cerebral desaturation events (CDEs) was 25%. The blood pressure drop 5 min after beach chair position measured at the acoustic meatus level in the CDE group was higher compared to patients without CDEs (p = 0.009) as was the rScO2 (p = 0.039) and the Vmax MCA (p = 0.002). There were no neurological deficits but patients with CDEs showed a greater negative impact on neurobehavioral tests 24 h after surgery compared to patients without CDEs (p = 0.001). CONCLUSIONS: In ASA I-II patients intravenous general anesthesia and controlled hypotension in the beach chair position affects cerebral blood flow and cerebral oxygenation with impact on the neurobehavioral outcome.

PMID- 30292742 TI - Noradrenergic modulation determines respiratory network activity during temperature changes in the in vitro brainstem of bullfrogs. AB - Among vertebrate ectotherms, air breathing frequency is generally constrained across warmer temperatures, but decreases during cooling. The brainstem mechanisms that give rise to this ventilatory strategy are unclear. Neuromodulation has recently been shown to stabilize motor circuit output across temperatures. Therefore, we tested the hypothesis that an important neuromodulatory system in respiratory control network, norepinephrine, produces this pattern of respiratory motor activity across temperatures. To this end, we used in vitro brainstem-spinal cord preparations from adult bullfrogs, Lithobates catesbeianus, to assess the role of noradrenergic signaling in shaping the frequency response of the respiratory network during temperature changes. We identified that noradrenergic signaling through the alpha1 adrenergic receptor constrains motor output from the respiratory network across warm temperatures. In contrast, the alpha2 adrenergic receptor actively inhibits respiratory motor output during cooling. These results indicate that noradrenergic tuning, rather than passive thermal responses, produces temperature responses of the respiratory circuits. PMID- 30292743 TI - Adults with Philadelphia Chromosome-Like Acute Lymphoblastic Leukemia: Considerations for Allogeneic Hematopoietic Cell Transplantation in First Complete Remission. AB - Philadelphia chromosome-like (Ph-like) acute lymphoblastic leukemia (ALL) is a subset of high-risk B cell ALLs. A large proportion of Ph-like ALL cases carry activating kinase mutations that could potentially allow them to be targeted by tyrosine kinase inhibitors. Ph-like ALL is not an uncommon entity, especially among adults, with a frequency exceeding 20%, including in older patients (>60 years old) with ALL. Ph-like ALL is associated with inferior outcomes across all ages, and studies have consistently shown a higher incidence of persistent postinduction minimal residual disease in patients carrying Ph-like ALL compared with other subgroups of ALL, and this translates into inferior leukemia-related outcomes. The inferior outcome of conventional chemotherapy for Ph-like ALL in adults raises the fundamental question of whether all adults with Ph-like ALL require an allogeneic hematopoietic cell transplantation (HCT) in first complete remission (CR1) regardless of other presenting features and treatment response parameters. Here we present and discuss several scenarios in which adults with Ph like ALL underwent or were considered for HCT in CR1 for various reasons. Although the decision to proceed with HCT was clear and indisputable in some of these situations, in others we struggled with the decision to transplant in CR1 because of the lack of published data regarding the efficacy of allogeneic HCT as consolidation for Ph-like ALL. We emphasize the urgent need for developing well designed studies to address this important question. PMID- 30292744 TI - A Randomized, Double-Blind, Placebo-Controlled Phase 3 Trial of Oral Brincidofovir for Cytomegalovirus Prophylaxis in Allogeneic Hematopoietic Cell Transplantation. AB - Cytomegalovirus (CMV) infection is a common complication of allogeneic hematopoietic cell transplantation (HCT). In this trial, we randomized adult CMV seropositive HCT recipients without CMV viremia at screening 2:1 to receive brincidofovir or placebo until week 14 post-HCT. Randomization was stratified by center and risk of CMV infection. Patients were assessed weekly through week 15 and every third week thereafter through week 24 post-HCT. Patients who developed clinically significant CMV infection (CS-CMVi; CMV viremia requiring preemptive therapy or CMV disease) discontinued the study drug and began anti-CMV treatment. The primary endpoint was the proportion of patients with CS-CMVi through week 24 post-HCT; patients who discontinued the trial or with missing data were imputed as primary endpoint events. Between August 2013 and June 2015, 452 patients were randomized at a median of 15 days after HCT and received study drug. The proportion of patients who developed CS-CMVi or were imputed as having a primary endpoint event through week 24 was similar between brincidofovir-treated patients and placebo recipients (155 of 303 [51.2%] versus 78 of 149 [52.3%]; odds ratio, .95 [95% confidence interval, .64 to 1.41]; P = .805); fewer brincidofovir recipients developed CMV viremia through week 14 compared with placebo recipients (41.6%; P < .001). Serious adverse events were more frequent among brincidofovir recipients (57.1% versus 37.6%), driven by acute graft-versus-host disease (32.3% versus 6.0%) and diarrhea (6.9% versus 2.7%). Week 24 all-cause mortality was 15.5% among brincidofovir recipients and 10.1% among placebo recipients. Brincidofovir did not reduce CS-CMVi by week 24 post-HCT and was associated with gastrointestinal toxicity. PMID- 30292745 TI - Over-expression of PD-1 Does Not Predict Leukemic Relapse after Allogeneic Stem Cell Transplantation. AB - Blockade of the T-cell exhaustion marker PD-1 to re-energize the immune response is emerging as a promising cancer treatment. Relapse of hematologic malignancy after allogeneic stem cell transplantation limits the success of this approach, and PD-1 blockade may hold therapeutic promise. However, PD-1 expression and its relationship with post-transplant relapse is poorly described. Because the donor immunity is activated by alloresponses, PD-1 expression may differ from nontransplanted individuals, and PD-1 blockade could risk graft-versus-host disease. Here we analyzed T-cell exhaustion marker kinetics and their relationship with leukemia relapse in 85 patients undergoing myeloablative T-cell depleted HLA-matched stem cell transplantation. At a median follow-up of 3.5 years, 35 (44%) patients relapsed. PD-1 expression in CD4 and CD8 T cells was comparably elevated in relapsed and nonrelapsed cohorts. Helios+ regulatory T cells and CD8 effector memory cells at day 30 emerged as independent predictors of relapse. Although leukemia antigen-specific T cells did not overexpress PD-1, single-cell analysis revealed LAG3 and TIM3 overexpression at relapse. These findings indicate that PD-1 is an unreliable marker for leukemia-specific T-cell exhaustion in relapsing patients but implies other exhaustion markers and suppressor cells as relapse biomarkers. PMID- 30292746 TI - Late Mortality after Allogeneic Blood or Marrow Transplantation for Inborn Errors of Metabolism: A Report from the Blood or Marrow Transplant Survivor Study-2 (BMTSS-2). AB - Allogeneic blood or marrow transplantation (BMT) is currently considered the standard of care for patients with specific inborn errors of metabolism (IEM). However, there is a paucity of studies describing long-term survival and cause specific late mortality after BMT in these patients with individual types of IEM. We studied 273 patients who had survived >=2 years after allogeneic BMT for IEM performed between 1974 and 2014. The most prevalent IEM in our cohort were X linked adrenoleukodystrophy (ALD; 37.3%), Hurler syndrome (35.1%), and metachromatic leukodystrophy (MLD; 10.2%). Conditional on surviving >=2 years after BMT, the overall survival for the entire cohort was 85.5 +/- 2.4% at 10 years and 73.5 +/- 3.7% at 20 years. The cohort had a 29-fold increased risk of late death compared with an age- and sex-matched cohort from the general US population (95% CI, 22- to 38-fold). The increased relative mortality was highest in the 2- to 5-year period after BMT (standardized mortality ratio [SMR], 207; 95% confidence interval [CI], 130 to 308) and declined with increasing time from BMT, but remained elevated for >=21 years after BMT (SMR, 9; 95% CI, 4 to 18). Sequelae from the progression of primary disease were the most common causes of late mortality in this cohort (76%). The use of T cell-depleted grafts in patients with ALD and Hurler syndrome was a risk factor for late mortality. Younger age at BMT and use of busulfan and cyclosporine were protective in patients with Hurler syndrome. Our findings demonstrate relatively favorable overall survival in >=2-year survivors of allogeneic BMT for IEM, although primary disease progression continues to be responsible for the majority of late deaths. PMID- 30292747 TI - Survival and Functional Outcomes in Boys with Cerebral Adrenoleukodystrophy with and without Hematopoietic Stem Cell Transplantation. AB - Cerebral adrenoleukodystrophy (CALD) is a rapidly progressing, often fatal neurodegenerative disease caused by mutations in the ABCD1 gene, resulting in deficiency of ALD protein. Clinical benefit has been reported following allogeneic hematopoietic stem cell transplantation (HSCT). We conducted a large multicenter retrospective chart review to characterize the natural history of CALD, to describe outcomes after HSCT, and to identify predictors of treatment outcomes. Major functional disabilities (MFDs) were identified as having the most significant impact on patients' abilities to function independently and were used to assess HSCT outcome. Neurologic function score (NFS) and Loes magnetic resonance imaging score were assessed. Data were collected on 72 patients with CALD who did not undergo HSCT (untreated cohort) and on 65 patients who underwent transplantation (HSCT cohort) at 5 clinical sites. Kaplan-Meier (KM) estimates of 5-year overall survival (OS) from the time of CALD diagnosis were 55% (95% confidence interval [CI], 42.2% to 65.7%) for the untreated cohort and 78% (95% CI, 64% to 86.6%) for the HSCT cohort overall (P = .01). KM estimates of 2-year MFD-free survival for patients with gadolinium-enhanced lesions (GdE+) were 29% (95% CI, 11.7% to 48.2%) for untreated patients (n = 21). For patients who underwent HSCT with GdE+ at baseline, with an NFS <=1 and Loes score of 0.5 to <=9 (n = 27), the 2-year MFD-free survival was 84% (95% CI, 62.3% to 93.6%). Mortality rates post-HSCT were 8% (5 of 65) at 100 days and 18% (12 of 65) at 1 year, with disease progression (44%; 7 of 16) and infection (31%; 5 of 16) listed as the most common causes of death. Adverse events post-HSCT included infection (29%; 19 of 65), acute grade II-IV graft-versus-host disease (GVHD) (31%; 18 of 58), and chronic GVHD (7%; 4 of 58). Eighteen percent of the patients (12 of 65) experienced engraftment failure after their first HSCT. Positive predictors of OS in the HSCT cohort may include donor-recipient HLA matching and lack of GVHD, and early disease treatment was predictive of MFD-free survival. GdE+ status is a strong predictor of disease progression in untreated patients. This study confirms HSCT as an effective treatment for CALD when performed early. We propose survival without MFDs as a relevant treatment goal, rather than solely assessing OS as an indicator of treatment success. PMID- 30292748 TI - Process control and in vitro/in vivo evaluation of aripiprazole sustained-release microcrystals for intramuscular injection. AB - This work describes the preparation of aripiprazole sustained-release microcrystals for intramuscular injection, through recrystallization, drying, wet grinding, and solidification steps, which had a great impact on the product quality. Here, we evaluated the crystal form of the drug in each step by differential scanning calorimetry (DSC), powder X-ray diffraction (PXRD), and fourier transform infrared spectroscopy (FT-IR), demonstrating that there is no change in the crystal form of aripiprazole monohydrate (H1) during grinding and freeze-drying. Microscopy and scanning electron microscopy (SEM) data showed that freeze-drying had no effect on the morphology of milled H1, and thermal gravimetric analysis (TGA) results showed that the freeze-dried formulation had acceptable water content. In particular, in this study, a similarity factor fitting was applied to determine the similarity of the particle size cumulative distribution curve, and the similarity factor value (99.00) showed that there was no change in the particle size distribution before and after freeze-drying. A two chamber transmembrane method was used to investigate the in vitro release of the aripiprazole sustained-release microcrystal (ALSI) and commercial preparations (Abilify Maintena(r)). The similarity factor fitting of in vitro release profiles and drug cumulative release curves in vivo yielded similarity factor values of 98.00 and 95.43, respectively, indicating similar in vitro release and in vivo bioavailability of rats between the ALSI and Abilify Maintena(r). A single-dose administration could produce long-term effects for a month. For a microcrystalline suspension, in addition to the conventional quality control indicators, the similarity of the cumulative particle size distribution, the in vitro release profile, and the similarity of the drug release percentage in vivo can be used to reflect product quality and process control. PMID- 30292749 TI - A novel multivalent DNA helix-based inhibitor showed enhanced anti-HIV-1 fusion activity. AB - DNA helix-based HIV-1 fusion inhibitors have been discovered as potent drug candidates, but further research is required to enhance their efficiency. The trimeric structure of the HIV-1 envelope glycoprotein provides a structural basis for multivalent drug design. In this work, a "multi-domain" strategy was adopted for design of an oligodeoxynucleotide with assembly, linkage, and activity domains. Built on the self-assembly of higher-order nucleic acid structure, a novel category of multivalent DNA helix-based HIV-1 fusion inhibitor could be easily obtained by a simple annealing course in solution buffer, with no other chemical synthesis for multivalent connection. An optimized multivalent molecule, M4, showed significantly higher anti-HIV-1 fusion activity than did corresponding monovalent inhibitors. Examination of the underlying mechanism indicated that M4 could interact with HIV-1 glycoproteins gp120 and gp41, thereby inhibiting 6HB formation in the fusion course. M4 also showed anti-RDDP and anti-RNase H activity of reverse transcriptase. Besides, these assembled molecules showed improved in vitro metabolic stability in liver homogenate, kidney homogenate, and rat plasma. Moreover, little acute toxicity was observed. Our findings aid in the structural design and understanding of the mechanisms of DNA helix-based HIV-1 inhibitors. This study also provides a general strategy based on a new structural paradigm for the design of other multivalent nucleic acid drugs. PMID- 30292750 TI - Nanostructured lipid carriers versus solid lipid nanoparticles for the potential treatment of pulmonary hypertension via nebulization. AB - With the non-selective vasodilating action, short half-life and first-pass metabolism of sildenafil (SC), local application in the lung for pulmonary arterial hypertension is of high demand. Although several nanosystems have been lately investigated, nanostructured lipid carriers (NLCs) give promises of potential safety, biodegradability and controlled drug release. In the current study, NLCs comprising either precirol, stearic acid or beeswax as solid lipid in presence of oleic acid as liquid lipid and PVA or poloxamer as emulsifier were prepared. Optimized NLCs (200-268 nm in size) were appraised versus SLNs both in vitro and in vivo. Precirol/PVA-based SLNs and NLCs ensued high entrapment efficiencies (EE > 95%) and controlled release behaviour over 6 h even though NLCs showed higher release profile. Stability studies at 4 degrees C indicated potential colloidal and entrapment stability over 3 months. Interestingly, NLCs demonstrated efficient nebulization, low interaction with mucin and higher viability of A549 cells (3-fold increase in IC50 relative to SLNs) providing good aptitudes for pulmonary application. In vivo administration of free SC in rats revealed localized intra-alveolar bleeding, presumably related to excessive vasodilatation. Meanwhile, the nanoencapsulated drug confirmed normal lung parenchyma with minimal incidence of bleeding. Inspiring results highlight the potential of sildenafil-laden nanostructured lipid carriers as pulmonary drug delivery system. PMID- 30292751 TI - Risk analysis and seroprevalence of HEV in people living with HIV/AIDS in Brazil. AB - Acute Hepatitis E virus (HEV) infection in people living with HIV/AIDS (PLHA) can lead to fulminant hepatic failure, cirrhosis and death. The prevalence of anti HEV antibodies within this group varies according to the geographical area. However, in South America, studies concerning the detection of HEV in PLHA are rare. Here, we investigated the presence of HEV by serological and molecular detection and evaluated the risk factors associated with infection in PLHA in Pernambuco state, Brazilian Northeast. Serological and molecular detection of HEV was performed in 366 samples of PLHA by ELISA for anti-HEV IgG and RT-PCR, respectively. Anti-HEV IgG prevalence was 4.1% (15/366) and no HEV RNA was detected. Concerning the risk factors, we evaluated, in multivariable analysis, age, years of school, sexual orientation, oral-anal sex, use of injectable drugs and piped water. Among them, only piped water availability could be associated with the HEV infection in PLHA (OR: 0.08; CI 95%: 0.01-0.66; p = 0.0182). This study showed for the first time the association of piped water as protection factor for HEV infection in PLHA. Finally, this is also the first report of HEV seroprevalence in PLHA in the Northeast Brazil. PMID- 30292752 TI - Resorption behaviour of the articular surface dome and functional outcome after open reduction and internal fixation of mandibular condylar head fractures using small-fragment positional screws. AB - PURPOSE: The aim of the study was to evaluate the resorption of the mandibular condylar head after open reduction and internal fixation of fractures with small fragment screws and to evaluate the functional outcome. PATIENTS AND METHOD: Forty-eight patients (55 condylar head fractures) underwent surgical treatment. All kinds of complications were recorded. In a subgroup of 20 patients, the average loss of bone height of the condylar head joint surface was gauged by measuring the vertical distances from 3 selected reference points of the fixation hardware to the vertex of the condyle in views of multiplanar radiographs after 6 months. Functional outcome was analysed by Helkimo index score. RESULTS: Complication rates were low. Osteosynthesis loosening occurred in 4 cases. The mean bone resorption along the condylar head joint surface in the subgroup of 20 patients (with 23 joints) was 0.7 mm. Functional outcome was rated as follows: 8 patients - good, 11 patients - slightly impaired, 1 patient - moderately impaired. CONCLUSION: Open reduction and internal fixation of condylar head fractures with small-fragment screws leads to reliable results in terms of joint surfaces relatively resistant to resorption and function. Low bone resorption on the joint surface of the condylar head can be expected. PMID- 30292753 TI - Expression of the alternative splicing variants of bcl6b in medaka Oryzias latipes. AB - Bcl6B, also known as BAZF, plays important roles in the immune response, repression of cancers, and maintenance of spermatogonial stem cells in mammals. In this study, the homologous gene bcl6b and its 5 alternative splicing variants, namely bcl6bX1 to bcl6bX5, were isolated from medaka fish, Oryzias latipes. Medaka bcl6b possesses conserved domains such as BTB domain, RD2 domain and four zinc fingers. Medaka bcl6bX1 to bcl6bX3 possess all three previously mentioned domains with minor differences in sequences. Medaka bcl6bX4 possesses only the BTB domain due to premature stopping, and bcl6bX5 possesses both the BTB domain and zinc fingers without the RD2 domain. Medaka bcl6b was expressed in the tissues including the brain, heart, gill, muscle, spleen, kidney, intestine, ovary and testes of adult fish. Medaka bcl6b was expressed in the embryos from very early stage, and could be detected clearly in the developing eyes by RT-PCR and in situ hybridization. Medaka bcl6b could respond to the stimuli of polyI:C and LPS in the kidney and spleen. Medaka bcl6bX1 to bcl6bX3 were the majority of the variants expressed in the adult tissues and the embryos, and were the major response to the stimulation of polyI:C and LPS in the spleen. These results suggested that bcl6b, including its isoforms, could function in various tissues and embryogenesis. Moreover, bcl6b might be a factor for immune response in medaka. PMID- 30292754 TI - Expression patterns and ligand binding characterization of Plus-C odorant-binding protein 14 from Adelphocoris lineolatus (Goeze). AB - Odorant-binding proteins (OBPs) can bind and transport hydrophobic odorants across the sensillum lymph to the olfactory receptors (ORs) and play crucial roles in insect chemosensory systems. Although the ligand spectra of classical OBPs have been extensively characterized, little is known about OBPs in the Plus C subgroup. Here, we focus on AlinOBP14, a Plus-C OBP from the hemipteran mirid bug pest Adelphocoris lineolatus (Goeze). Quantitative real-time PCR experiments suggest that AlinOBP14 is ubiquitously expressed at different developmental stages but is highly expressed in the adult head, the non-chemosensory organ. Fluorescence-based competitive binding assays show that beta-ionone, nerolidol, farnesol and insect juvenile hormone III (JHIII) strongly bind to AlinOBP14. No significant internal binding pocket is predicted by homology modeling. Instead, the long N-terminal and C-terminal regions and parts of several alpha-helixes form a cupped cavity to accommodate ligands. Molecular docking reveals that the four potential ligands have distinct binding orientations, implying different roles of the N-terminal extension in ligand recognition. This hypothesis is further confirmed via a ligand binding assay in which the recombinant N-terminal mutant AlinOBP14 displays comparable binding affinities for beta-ionone and trans, trans-farnesol but decreased binding affinities for nerolidol and JHIII. Thus, our current study is the first to characterize the ligand binding spectra of a Plus-C OBP in hemipteran insect species and reveals that N-terminal extensions could be required for its recognition of putative ligands. PMID- 30292755 TI - A novel selenonucleoside suppresses tumor growth by targeting Skp2 degradation in paclitaxel-resistant prostate cancer. AB - Prostate cancer (PC) is the most common disease in men over age 50, and its prevalence rate has been gradually increasing since 1980. Taxane-derived anticancer agents are the primary agents used to treat metastatic prostate cancer patients; however, the side effects and acquired drug resistance limit the success of these therapies. Because there is no specific treatment for paclitaxel resistant prostate cancer, it is necessary to develop new targets and therapeutic strategies to overcome the acquired resistance. In this study, the antitumor activity of a novel selenonucleoside (4'-selenofuranosyl-2,6-dichloropurine, LJ 2618), a third-generation nucleoside, and its plausible mechanisms of action in paclitaxel-resistant prostate cancer (PC-3-Pa) cells were investigated. The established PC-3-Pa cells exhibited over 100-fold resistance against paclitaxel compared to the paclitaxel-sensitive PC-3 cells. LJ-2618, however, effectively inhibited the proliferation of both cell lines with similar IC50 values in vitro. In PC-3-Pa cells, the activated PI3K/Akt signaling pathway was suppressed by LJ 2618 treatment. In addition, Skp2 was found to be over-expressed in paclitaxel resistant cells, and the transfection of Skp2 siRNA recovered the sensitivity of paclitaxel in PC-3-Pa cells. Furthermore, LJ-2618 significantly down-regulated Skp2 expression in PC-3-Pa cells by promoting degradation and inducing destabilization of Skp2, which triggers G2/M cell cycle arrest. In a xenograft mouse model implanted with PC-3-Pa cells, LJ-2618 (3 or 10 mg/kg) effectively inhibited tumor growth with the enhancement of Skp2 degradation and induction of p27 expression in tumor tissues. These findings suggest that LJ-2618 may have potential for overcoming paclitaxel resistance via promoting Skp2 degradation and stabilizing p27 expression in PC-3-Pa cells. Therefore, the novel selenonucleoside LJ-2618 may lead to the development of a new treatment strategy for patients with paclitaxel-resistant, castration-resistant prostate cancer. PMID- 30292756 TI - Probing structure-activity relationship in beta-arrestin2 recruitment of diversely substituted adenosine derivatives. AB - In the adenosine receptor (AR) subfamily of G protein-coupled receptors (GPCRs), biased agonism has been described for the human A1AR, A2BAR and A3AR. While diverse A3AR agonists have been evaluated for receptor binding and Gi-mediated cAMP signalling, the beta-arrestin2 (betaarr2) pathway has been left largely unexplored. We screened nineteen diverse adenosine derivatives for betaarr2 recruitment using a stable hA3AR-NanoBit(r)-betaarr2 HEK293T cell line. Their activity profiles were compared with a cAMP accumulation assay in stable hA3AR CHO cells. Structural features linked to betaarr2 activation were further investigated by the evaluation of an additional ten A3AR ligands. The A3AR selective reference agonist 2-Cl-IB-MECA, which is a full agonist in terms of cAMP inhibition, only showed partial agonist behaviour in betaarr2 recruitment. Highly A3AR-selective (N)-methanocarba 5'-uronamide adenosine derivatives displayed higher potency in both cAMP signalling and betaarr2 recruitment than reference agonists NECA and 2-Cl-IB-MECA. Their A3AR-preferred conformation tolerates C2-position substitutions, for increased betaarr2 efficacy, better than the flexible scaffolds of ribose derivatives. The different amino functionalities in the adenosine scaffold of these derivatives each seem to be important for signalling as well. In conclusion, we have provided insights into ligand features that can help to guide the future therapeutic development of biased A3AR ligands with respect to G-protein and betaarr2 signalling. PMID- 30292757 TI - C-terminal degradation of PYY peptides in plasma abolishes effects on satiety and beta-cell function. AB - The importance of dipeptidyl peptidase-4 mediated N-terminal metabolism of the enteroendocrine-derived hormone, peptide YY (PYY), for receptor binding and subsequent biological action profile is well established. However, an intact C terminus may be fundamental also for bioactivity of PYY peptides. The current study has demonstrated C-terminal degradation of the major recognised circulating forms of PYY, PYY(1-36) and PYY(3-36), in plasma, resulting in production of PYY(1-34) and PYY(3-34). Interestingly, the angiotensin-converting-enzyme (ACE) inhibitor, captopril, blocked formation of PYY(3-34) from PYY(3-36) in plasma, but did result in the appearance of PYY(3-35). In addition, we were able to evidence C-terminal truncation of PYY(1-35) and PYY(3-35) to PYY(1-34) and PYY(3 34), respectively. As expected, PYY(1-36) and PYY(3-36) inhibited (P < 0.05-P < 0.001) glucose- and alanine-stimulated insulin secretion from BRIN-BD11 beta cells. In contrast, PYY(1-34), PYY(3-34), PYY(1-35) and PYY(3-35) were devoid of insulinostatic actions. Both PYY(1-36) and PYY(3-36), but not related PYY metabolites, significantly (P < 0.05-P < 0.001) enhanced proliferation of BRIN BD11 and 1.1B4 beta-cell lines, and protected (P < 0.01-P < 0.001) these cell lines against cytokine-induced apoptosis. As expected, PYY(3-36) induced clear (P < 0.05-P < 0.01) appetite suppressive effects in mice, but this action was eliminated by mono- or di-peptide C-terminal truncation. Interestingly, captopril significantly (P < 0.05) augmented the anorexigenic effects of PYY(3-36) in mice. PYY(1-36), PYY(3-36), PYY(1-34) and PYY(3-34) lacked effects on in vivo glucose tolerance or glucose-induced insulin release. Taken together, these data highlight the unrecognised importance of C-terminal integrity of PYY peptides for biological activity and therapeutic usefulness in obesity-diabetes. PMID- 30292758 TI - CT Imaging-Based Low-Attenuation Super Clusters in Three Dimensions and the Progression of Emphysema. AB - BACKGROUND: Distributions of low-attenuation areas in two-dimensional (2-D) CT lung slices are used to quantify parenchymal destruction in patients with COPD. However, these segmental approaches are limited and may not reflect the true three-dimensional (3-D) tissue processes that drive emphysematous changes in the lung. The goal of this study was to instead evaluate distributions of 3-D low attenuation volumes, which we hypothesized would follow a power law distribution and provide a more complete assessment of the mechanisms underlying disease progression. METHODS: CT scans and pulmonary function test results were acquired from an observational database for N = 12 patients with COPD and N = 12 control patients. The data set included baseline and two annual follow-up evaluations in patients with COPD. Three-dimensional representations of the lungs were reconstructed from 2-D axial CT slices, with low-attenuation volumes identified as contiguous voxels < -960 Hounsfield units. RESULTS: Low-attenuation sizes generally followed a power law distribution, with the exception of large, individual outliers termed "super clusters," which deviated from the expected distribution. Super cluster volume was correlated with disease severity (% total low attenuation, rho = 0.950) and clinical measures of lung function including FEV1 (rho = -0.849) and diffusing capacity of the lung for carbon monoxide Dlco (rho = -0.874). To interpret these results, we developed a personalized computational model of super cluster emergence. Simulations indicated disease progression was more likely to occur near existing emphysematous regions, giving rise to a biomechanical, force-induced mechanism of super cluster growth. CONCLUSIONS: Low-attenuation super clusters are defining, quantitative features of parenchymal destruction that dominate disease progression, particularly in advanced COPD. PMID- 30292759 TI - A simple clinical risk score (C2HEST) for predicting incident atrial fibrillation in Asian subjects: Derivation in 471,446 Chinese subjects, with internal validation and external application in 451,199 Korean subjects. AB - BACKGROUND: The incidence of atrial fibrillation (AF) is increasing, conferring a major healthcare issue in Asia. No risk score for predicting incident AF has been specifically developed in Asian subjects. Our aim was to investigate risk factors for incident AF in Asian subjects and to combine them into a simple clinical risk score. METHODS: Risk factors for incident AF were analyzed in 471,446 subjects from the Chinese Yunnan Insurance Database (internal derivation cohort), and then combined into a simple clinical risk score. External application of the new score was performed in 451,199 subjects from the Korean National Health Insurance Service (external cohort). RESULTS: In the internal cohort, structural heart disease (SHD), heart failure (HF), age>=75 years, coronary artery disease (CAD), hyperthyroidism, chronic obstructive pulmonary disease (COPD) and hypertension were associated with incident AF. Given the low prevalence and the strong association of SHD with incident AF (hazard ratio: 26.07 [18.22-37.30], p<0.001), these patients should be independently considered as 'high-risk' for AF and were excluded from the analysis. The remaining predictors were combined into the new simple C2HEST score: C2: CAD / COPD (1 point each); H: Hypertension; E: Elderly (Age>=75, doubled); S: Systolic HF (doubled); T: Thyroid disease (hyperthyroidism). The C2HEST score showed good discrimination with AUC 0.75 [0.73-0.77] and had good calibration (p=0.774). The score was internally validated by bootstrap sampling procedure, giving an AUC of 0.75 [0.73-0.77]. External application gave an AUC of 0.65 [0.65-0.66]. The C2HEST score was superior to CHADS2 and CHA2DS2VASc scores in both cohorts in predicting incident AF. CONCLUSIONS: We have developed and validated the C2HEST score as a simple clinical tool to assess the individual risk of developing AF in the Asian population without SHD. PMID- 30292760 TI - Safety and Efficacy of Remimazolam Compared to Placebo and Midazolam for Moderate Sedation during Bronchoscopy. AB - BACKGROUND: While the complexity of flexible bronchoscopy has increased, standard options for moderate sedation medications have not changed in three decades. There is need to improve moderate sedation while maintaining safety. Remimazolam was developed to address shortcomings of current sedation strategies. METHODS: A prospective, double-blind, randomized, multi-center, parallel group trial was performed at 30 U.S. sites. The efficacy and safety of remimazolam for sedation during flexible bronchoscopy were compared to placebo and open-label midazolam. RESULTS: The success rates were 80.6% in the remimazolam arm, 4.8% in the placebo arm (p<0.0001), and 32.9% in the midazolam arm. Bronchoscopy was started sooner in the remimazolam arm (mean 6.4+/-5.82 minutes) compared to placebo (17.2+/-4.15 minutes, p<0.0001), and midazolam (16.3+/-8.60 minutes). Time to full alertness after the end of bronchoscopy was significantly shorter in patients treated with remimazolam (median 6.0 minutes, 95% CI: 5.2; 7.1) compared to those treated with placebo (13.6 minutes, 95% CI: 8.1; 24.0; p=0.0001) and midazolam (12.0 minutes, 95% CI: 5.0; 15.0). Remimazolam registered superior restoration of neuropsychiatric function compared to placebo and midazolam. Safety was comparable among all 3 arms, and 5.6% of the patients in the remimazolam group had serious Treatment Emergent Adverse Events (TEAEs) as compared to 6.8% in the placebo group. CONCLUSIONS: Remimazolam administered under supervision of a pulmonologist was effective and safe for moderate sedation during flexible bronchoscopy. In an exploratory analysis, it demonstrated a shorter onset of action and faster neuropsychiatric recovery than midazolam. PMID- 30292762 TI - Asthma and immunology: a call for papers for AAAAI. PMID- 30292761 TI - Evidence for an Association Between Intrahepatic Vascular Changes and the Development of Hepatopulmonary Syndrome. AB - BACKGROUND: Hepatopulmonary syndrome (HPS) is characterized by an arterial oxygenation defect, defined by an increased alveolar-arterial oxygen gradient, induced by pulmonary vascular dilatations in the context of liver disease. The pathogenesis of HPS is poorly understood. Morphologic changes associated with HPS are unknown. This study aimed at describing imaging and pathology changes associated with HPS. METHODS: We performed a case-control study in candidates for transplant with suspicion of cirrhosis. Each patient with HPS (Pao2 <= 70 mm Hg) was matched to three control subjects for age, cause, and liver disease severity. Pretransplant thoracic and abdominal imaging and explanted livers were reviewed. RESULTS: CT scans and Doppler ultrasounds from 21 patients with HPS were compared with those from 63 control subjects. HPS was associated with a two- to threefold higher prevalence of obstructed intrahepatic portal branches, of slowed or hepatofugal portal blood flow, and of large abdominal portosystemic shunts. Hepatic artery diameter was also larger in patients with HPS. Explanted livers from 19 patients with HPS were compared with those from 57 control subjects. HPS was associated with a fourfold higher prevalence of portal venule thrombosis and a ninefold higher prevalence of extensive vascular proliferation within fibrous septa. Obstruction of centrilobular venules, sinusoidal dilatation, and liver parenchymal extinction were also more common in patients with HPS. CONCLUSIONS: HPS is associated with intrahepatic vascular changes and with features suggesting severe portal hypertension. These results raise the hypothesis that intrahepatic vascular changes precipitate the development of HPS, opening new therapeutic perspectives for HPS. PMID- 30292763 TI - Prevalence and molecular characteristics of methicillin-resistant Staphylococcus aureus among nasal carriage strains isolated from emergency department patients and healthcare workers in central Taiwan. AB - BACKGROUND AND OBJECTIVE: Screening and identification of methicillin-resistant Staphylococcus aureus (MRSA) carriage are helpful for controlling MRSA dissemination in hospitals. The aim of our study was to determine the prevalence of nasal carriages and diversity of MRSA among patients and healthcare workers (HCWs) at two regional hospitals in Taiwan. METHODS: Nasal swabs were obtained prospectively from 204 patients visiting the emergency department (ED) and 326 HCWs in two regional hospitals in Changhua, Taiwan, between February 2015 and June 2015. All the MRSA isolates were further molecularly characterized. RESULTS: Of the 204 participating patients, the nasal carriage rates of S. aureus and MRSA were 22.1% and 7.8%, respectively. For HCWs, the S. aureus and MRSA carriage rates were 26.1% and 6.1%, respectively. There was no statistically significant difference in MRSA carriage rate between patients and HCWs (P = 0.447). Patients receiving hemodialysis were significantly associated with MRSA colonization (P = 0.012). The leading three sequence types (ST) were ST59 (16, 44.4%), ST45 (11, 30.6%), and ST239 (3, 8.3%) for all 36 MRSA isolates. ST59/SCCmec IV/t437/PVL negative and ST45/SCCmec V/t1081/PVL-negative were the predominant clones among HCWs (30%) and participating patients (19%), respectively. CONCLUSION: Overall, a substantial proportion of patients visiting the ED and HCWs harbored CA-MRSA, mostly ST59 strains, in their nares. It is noteworthy that MRSA ST45 strains supplanted ST239 as the second leading nasal MRSA colonization strain in our study. PMID- 30292764 TI - Long-term Object Discrimination at Several Viewpoints Develops Neural Substrates of View-invariant Object Recognition in Inferotemporal Cortex. AB - Object recognition requires differentiation across different objects and generalization across views of the same object. We previously demonstrated that discrimination of object images at several views without any possibility of association was enough to achieve object recognition within a certain range of viewing angles and confirmed the response tolerance of monkey inferotemporal cells within a similar range of viewing angles. However, neither behavioral object recognition nor electrophysiological response tolerance was complete across views. In the present study, we extended such learning past performance saturation and recorded neuronal activity during the further learning period. When monkeys were trained to discriminate objects at several views, we found that they could discriminate the trained objects regardless of the eventual change in viewing angle, and confirmed a response tolerance at the population level over a large viewing angle range covering all the viewpoints experienced. At the cell population level, such overtraining leads to significantly higher neural response similarity for views of the same objects than for views of different objects regardless of the extent of viewing angle separation. These results suggest a possible method of view-invariant object recognition development. PMID- 30292765 TI - Testing the Central Gain Model: Loudness Growth Correlates with Central Auditory Gain Enhancement in a Rodent Model of Hyperacusis. AB - The central gain model of hyperacusis proposes that loss of auditory input can result in maladaptive neuronal gain increases in the central auditory system, leading to the over-amplification of sound-evoked activity and excessive loudness perception. Despite the attractiveness of this model, and supporting evidence for it, a critical test of the central gain theory requires that changes in sound evoked activity be explicitly linked to perceptual alterations of loudness. Here we combined an operant conditioning task that uses a subject's reaction time to auditory stimuli to produce reliable measures of loudness growth with chronic electrophysiological recordings from the auditory cortex and inferior colliculus of awake, behaviorally-phenotyped animals. In this manner, we could directly correlate daily assessments of loudness perception with neurophysiological measures of sound encoding within the same animal. We validated this novel psychophysical-electrophysiological paradigm with a salicylate-induced model of hearing loss and hyperacusis, as high doses of sodium salicylate reliably induce temporary hearing loss, neural hyperactivity, and auditory perceptual disruptions like tinnitus and hyperacusis. Salicylate induced parallel changes to loudness growth and evoked response-intensity functions consistent with temporary hearing loss and hyperacusis. Most importantly, we found that salicylate-mediated changes in loudness growth and sound-evoked activity were correlated within individual animals. These results provide strong support for the central gain model of hyperacusis and demonstrate the utility of using an experimental design that allows for within-subject comparison of behavioral and electrophysiological measures, thereby making inter-subject variability a strength rather than a limitation. PMID- 30292766 TI - Exploiting Drug-Apolipoprotein E Gene Interactions in Hypertension to Preserve Cognitive Function: The 3-City Cohort Study. AB - OBJECTIVES: The objective was to test the hypothesis that antihypertensive drugs have a differential effect on cognition in carriers and noncarriers of the apolipoprotein epsilon4 (APOE4) polymorphism. DESIGN: Prospective population based cohort, France. SETTING AND PARTICIPANTS: A total of 3359 persons using antihypertensive drugs (median age 74 years, 62% women) were serially assessed up to 10 years follow-up. MEASURES: Exposure to antihypertensive drug use was established in the first 2 years. Cognitive function was assessed at baseline, 2, 4, 7, and 10 years with a validated test battery covering global cognition, verbal fluency, immediate visual recognition memory, processing speed, and executive function. Clinically significant change in cognitive function was determined using reliable change indices represented as z scores and analyzed with linear mixed-models. RESULTS: From 3359 persons exposed to antihypertensive drugs, 653 were APOE4 carriers (5.1% homozygous, 94.9% heterozygous) and median follow-up was 5.2 years (interquartile range 3.7-8.0). In APOE4 carriers, improved general cognitive function over time was associated with exposure to angiotensin converting enzyme inhibitors [beta = .14; 95% confidence interval (CI) .06-.23, P = .001] and angiotensin receptor blockers (beta = .11; 95% CI .02 .21, P = .019). Improved verbal fluency was associated with angiotensin converting enzyme inhibitors (beta = .11; 95% CI .03-.20, P = .012). CONCLUSIONS: Renin-angiotensin-system blockade was associated with improved general cognitive function in APOE4 carriers. Findings did not support renin-angiotensin-system drugs' lipophilicity or ability to cross the blood-brain barrier as potential mechanisms. The findings have implications for selecting the optimal antihypertensive drug in older populations at risk of cognitive decline and dementia. PMID- 30292767 TI - The prevalence of low serum free testosterone and the short-term effect of anti retroviral therapy in male Japanese treatment-naive HIV patients. AB - OBJECTIVES: The prevalence of hypogonadism in HIV patients is still a matter of debate. Today, serum free testosterone (fTST) is thought to be more important than serum testosterone in the diagnosis of hypogonadism in patients with HIV. This study aimed to determine the prevalence of low fTST levels and the effects of anti-retroviral therapy (ART) on fTST levels in treatment-naive male Japanese patients with HIV. METHODS: Patients who visited Teikyo University Hospital, Japan between 2010 and 2016 were enrolled. Patients' fTST levels were evaluated twice with a radioimmunoassay in the morning, at the onset of ART and one year later. Clinical factors were also reviewed. The patients were divided into two groups ('hypogonadism' and 'normal') based on Japanese criteria. To determine factors related to low fTST in treatment-naive patients, the Mann-Whitney U test and a multiple-regression analysis were used. Changes in fTST levels after ART initiation were evaluated with a paired t-test. RESULTS: Data from 25 patients were collected. Their median age was 36.0 years, and the median fTST level was 8.00 pg/ml in the treatment-naive state. Thirteen patients (52%) were in the hypogonadism group. Low levels of fibroblast growth factor 23 were significantly related to low fTST levels. After the start of ART, fTST levels increased significantly (median 8.00 interquartile range [6.40-9.70] to 9.60 [7.60-13.10] pg/ml, p = 0.0081). CONCLUSIONS: Subnormal fTST levels occurred frequently among the present study patients in treatment-naive settings. Free testosterone levels in patients with HIV were significantly increased one year after the start of ART. PMID- 30292768 TI - Characterization of CTX-M type ESBL-producing Enterobacteriaceae isolated from asymptomatic healthy individuals who live in a community of the Okinawa prefecture, Japan. AB - This study was performed to characterize CTX-M type extended spectrum beta lactamase (ESBL)-producing Enterobacteriaceae carriage in asymptomatic health individuals, which has not been well investigated, in a community of the Okinawa prefecture, Japan. Fecal samples were voluntary collected from asymptomatic healthy individuals who were going to take a routine medical checkup. The collected fecal samples were inoculated on MacConkey agar supplemented with 2 MUg/ml of cefotaxime and incubated at 37 degrees C. Randomly selected three lactose-fermented colonies per each sample were analyzed. Genetic relatedness among the CTX-M type ESBL-producing Enterobacteriaceae isolates were performed by pulsed-field gel electrophoresis (PFGE) after confirmation of ESBL phenotype and determination of bacterial species. Location of blaCTX-M was confirmed by S1 PFGE, I-CeuI-PFGE and the Southern blotting hybridization. ESBL-producing Enterobacteriaceae was isolated from 32 (12.2%) of the collected 263 fecal samples, and 96 ESBL-producing Enterobacteriaceae isolates were obtained. CTX-M type ESBL-producing Escherichia coli B2 were major (67 isolates, 72.0%) and 40 (59.7%) of the 67 CTX-M type ESBL -producing E. coli B2 were E. coli B2-ST131. Three CTX-M type ESBL-producing E. coli B2-ST131 isolates from asymptomatic healthy individuals showed similar PFGE band patterns as five CTX-M type ESBL producing E. coli B2-ST131 isolates from a hospital locates in the same area of the target community. Chromosomally-transferred blaCTX-M was observed in 10.0% of the examined CTX-M type ESBL-producing Enterobacteriaceae isolates. We report current situation CTX-M type ESBL-producing Enterobacteriaceae carriage in asymptomatic healthy individuals of the Okinawa prefecture, Japan. In addition, our results indicated that worldwide distributed CTX-M type ESBL-producing E. coli B2-ST131 has been spread in a community. Therefore monitoring of ESBL producing Enterobacteriaceae in healthy individuals is important. PMID- 30292769 TI - Exploring microRNA profiles for circadian clock and flowering development regulation in Himalayan Rhododendron. AB - miRNA is a non-coding, yet crucial entity in remodeling the genetic architecture. Rhododendron arboreum of Himalayas grows and even flower under fluctuating climate. sRNA from leaves of vegetative and reproductive periods was sequenced to elucidate its seasonal associations. Conserved (256) and novel (210) miRNAs and their precursors were located based on homology with plant databases and transcriptome of the species. 27,139 predicted targets were involved with metabolism, reproduction, and response to abiotic stimuli. A comparative analysis showed differential expression of 198 miRNAs with season-specific abundance of 103 miRNAs. Specific isoforms of 11 miRNA families exhibited a temporal expression and targeted different genes implying a complex regulation. The variable miRNA expression among the tissues of different conditions can be associated with the adaptability of the species, which will prove essential for further study on miRNAs mediating seasonal response. Moreover, exogenous cues also mediate phase transition via networking of flowering pathways and their components. In this context, 18 known families and 77 novel miRNAs modulating 117 genes crucial in circadian entrainment were filtered. A negative correlation was obtained between the expression of 18 of these miRNAs and their targets when tested through quantitative-PCR. It highlighted the role of miRNA-target pairs in perceiving environmental variabilities and monitoring flowering growth. Furthermore, a phylogenetic clustering was performed, which supported the lineage specific evolution and function of putative miR156 sequence in the species. This documentation of genome-wide profiling of miRNA, their targets, and expression will enhance the understanding of developmental and climate-tolerance strategies in high-altitude trees. PMID- 30292770 TI - NO-sGC-cGMP signaling influence the anxiolytic like effect of lithium in mice in Light and dark box and elevated pus maze. AB - Glutamate is an excitatory neurotransmitter implicated in the pathogenesis of psychiatric disorders. Glutamate results in the activation of an enzyme called glycogen synthase kinase-3 (GSK-3) acting through N-methyl-D-aspartate (NMDA) receptors. Impaired expression of GSK-3 affects behavior and neurochemicals level in the brain responsible for the pathogenesis of mood disorders. It has been reported that lithium acts as an inhibitor of GSK-3 and inhibit the enzyme GSK-3 in an uncompetitive manner. In the present study, anxiolytic like effect of lithium in mice is investigated through light and dark box (LDB) and elevated pus maze (EPM). Lithium (50, 100 and 200 mg/kg, i.p.) was administered to the mice to determine the anxiety related behavior. Results obtained suggests that the administration of lithium (100 mg/kg, i.p.) reversed the anxiety related behavior of mice and decreased the levels of glutamate and nitrite as compared to control. Glutamate acting through the NMDA receptor has been found to regulate the expression of enzyme neuronal nitric oxide synthase (nNOS), which is responsible for the release of nitric oxide (NO), suggesting a possible link between NO and GSK-3 also. Therefore, to determine the possible interaction with NO, sub effective dose of lithium was administered in combination with NO donor i.e. L Arginine (50 mg/kg, i.p.), NOS and soluble guanylate cyclase (sGC) inhibitor i.e. methylene blue (1 mg/kg, i.p.) and phosphodiesterase inhibitor i.e. sildenafil (1 mg/kg, i.p.). The results obtained demonstrated that the anxiolytic like effect of lithium was abolished by the pretreatment with NO donor and potentiated by the pretreatment with NOS inhibitor. Therefore, it is suggested that NO signaling pathway influence the anxiolytic like activity of lithium in mice, further suggesting the link between the GSK-3 and NO signaling in the regulation of anxiety related behavior. PMID- 30292771 TI - The decline of whole-body glucose metabolism in ovariectomized rats. AB - Age is a major risk factor for developing chronic diseases, including type 2 diabetes and osteoporosis. Emerging evidences suggest that the disorder of bone metabolism in osteoporosis is involved in the pathogenesis of glucose intolerance, insulin resistance and type 2 diabetes. However, their etiology and relative regulatory factors still remain elusive to clinicians and researchers. In this study, rats were divided into two groups: normal sham surgery control and ovariectomized (OVX) groups. We evaluated the global bone parameters, glucose metabolism, protein and gene expressions in both skeletal muscle and adipocytes. The present findings showed that the bone mineral density (BMD) and compression load of bone were markedly reduced in OVX rats as revealed by micro-CT, dual energy X-ray absorptiometry and bone biomechanics analysis. Besides, plasma estrogen, total alkaline phosphatase (TALP) and osteocalcin levels were significantly decreased in the OVX rats, but body weight, fat mass and plasma tartrate-resistant acid phosphatase (TRAP) and chemerin levels were significantly increased in the OVX rats. More interestingly, we found that p-AKT, p-P38MAPK, glucose transporter 4 (GLUT4) and peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1alpha) contents as well as GLUT4 and PGC-1alpha mRNA expression were significantly decreased in skeletal muscle and adipocytes of OVX rats. In conclusion, our results indicated that whole-body glucose metabolism and glucose intolerance in OVX rats was degressive, suggesting there was a novel link between osteoporosis and whole body glucose homeostasis, which are controlled by the P38MAPK/PGC-1alpha/GLUT4 signaling pathway.

AB - The purpose of this study was to investigate healthy lifestyle behaviours across age categories in the older population in Chile. Data from 1390 older adults (>=60 years), in the 2009-2010 Chilean National Health Survey were analyzed. We derived the following age categories: 60-65, 66-70, 71-75, 76-80 and >80 years. The associations between age and compliance with healthy lifestyle behaviours (smoking, sitting time, physical activity, sleep duration and intake of salt, alcohol, fruit and vegetables) were investigated using logistic regression. The probability of meeting the guidelines for alcohol intake (OR trend: 1.35 [95% CI: 1.11; 1.64], p = 0.001) and smoking (OR trend: 1.23 [95% CI: 1.13; 1.33], p < 0.0001) increased with age, whereas spending <4 h per day sitting time or engaging in at least 150 min of physical activity per week or sleep on average between 7 and 9 h per day were less likely to be met with increasing age (OR trend: 0.77 [95% CI: 0.71; 0.83], p < 0.000; OR trend: 0.73 [95% CI: 0.67; 0.79], p < 0.0001, and OR trend: 0.89 [95% CI: 0.82; 0.96], p = 0.002, respectively). No significant trend across age categories was observed for fruit and vegetables, and salt intake. The probability of meeting at least 3 out of 7 healthy lifestyle behaviours across the age categories was also lower in older age categories compared to those aged 60 to 65 years. Overall, in older adults the probability of having the healthy lifestyle behaviours of physical activity, sitting time and sleeping behaviours was low but not for smoking or alcohol consumption. With an increasingly ageing population, these findings could inform stakeholders on which lifestyle behaviours could be targeted in the older adults and therefore which interventions should take place to promote healthy ageing. PMID- 30292773 TI - Pragmatic Trial to Evaluate the Effect of a Promotora Telephone Intervention on the Duration of Breastfeeding. AB - OBJECTIVE: To evaluate the effectiveness of a telephone intervention delivered by promotoras (lay health care workers) to increase the duration of exclusive breastfeeding (EBF) in Hispanic women at 12 weeks postpartum. Secondary objectives were to assess breastfeeding duration (BFD) and to evaluate background variables that may be associated with EBF and BFD. DESIGN: Pragmatic trial. SETTING: Two obstetric clinics affiliated with a community medical center in Southern California. PARTICIPANTS: We recruited 61 participants from the two clinics. Participants were 18 to 45 years old and planned to breastfeed their infants. Women who showed interest in the study were sequentially divided into an intervention (n = 31) or a control group (n = 30). METHODS: The intervention consisted of telephone support for breastfeeding provided by certified and trained promotoras. RESULTS: Fourteen out of 31 (45%) participants in the intervention group continued to practice EBF compared with 4 out of 30 (13%) in the control group (odds ratio = 3.39, p = .04). Breastfeeding duration in days was significantly longer for the participants in the intervention group (F =1/59 = 29.88, p < .01). The positive predictors of EBF at 12 weeks after birth were prior breastfeeding experience, perceived breastfeeding support, promotora telephone support, and higher scores on the acculturation scale. Positive predictors of BFD were breastfeeding support, promotora telephone support, and higher scores on breastfeeding self-efficacy. A negative predictor was lower household income. CONCLUSION: Our results indicate that a telephone support intervention delivered by promotoras may increase the rates of EBF by threefold at 12 weeks after birth. PMID- 30292774 TI - Relationship Between Mindfulness and Posttraumatic Stress in Women Who Experienced Stillbirth. AB - OBJECTIVE: To explore the potential factors that mediate the relationship between mindfulness and symptoms of posttraumatic stress (PTS) in women who experienced stillbirth. DESIGN: A cross-sectional analysis of baseline data before women's participation in an online mindfulness intervention (i.e., online yoga). SETTING: This was a national study, and women participated in their own homes. PARTICIPANTS: Women who experienced stillbirth (N = 74) within the past 2 years and resided in the United States. METHODS: Women were recruited nationally, primarily through social media. Participants (N = 74) completed baseline assessments (self-report mental and physical health surveys) via a Web-based survey tool. We conducted an exploratory factor analysis of the COPE Inventory subscales to reduce the number of variables before entry into a mediation model. We then tested the mediation effects of sleep quality, self-esteem, resilience, and maladaptive coping on the relationship between mindfulness and PTS symptoms. RESULTS: Through the exploratory factor analysis we identified a two-factor solution. The first factor included nine subscales that represented adaptive coping strategies, and the second factor included five subscales that represented maladaptive coping strategies. Results from multiple mediation analysis suggested that mindfulness had a significant inverse relationship to PTS symptoms mediated by sleep quality. CONCLUSION: Mindfulness practices may have potential benefits for grieving women after stillbirth. Evidence-based approaches to improve sleep quality also may be important to reduce PTS symptoms in women after stillbirth. PMID- 30292775 TI - Implementation of Delayed Cord Clamping in Vigorous Preterm Neonates. AB - OBJECTIVE: To adopt evidence-based recommendations to delay cord clamping in vigorous preterm neonates. DESIGN: Evidence-based practice change project with quantitative data. SETTING/LOCAL PROBLEM: Delayed cord clamping (DCC) was not a usual practice at the hospital where this project took place, despite research findings that show benefits of DCC for preterm neonates. PARTICIPANTS: Vigorous neonates born before 37 weeks completed gestation. INTERVENTION/MEASUREMENT: An interprofessional obstetric team of obstetricians and registered nurses implemented DCC for up to 1 minute for vigorous preterm neonates. RESULTS: We found that Apgar scores at 1 minute (mean [M] = 8.35, standard deviation [SD] = .551, n = 31) were statistically significantly higher with DCC than at 1 minute with immediate cord clamping (M = 7.16, SD = 1.834, n = 19) at t (20.008) = 1.197, p = .012. The Apgar scores at 5 minutes (M = 9.00, SD = 0.258, n = 31) were statistically significantly higher with DCC than at 5 minutes with immediate cord clamping (M = 8.58, SD = .838, n = 19) at t (20.116) = 2.130, p = 0.046. CONCLUSION: Delayed cord clamping was adopted as a usual clinical practice, and implementation of this practice in vigorous preterm neonates increased their Apgar scores. The obstetric team's awareness, experience, and professional perspectives about DCC improved. PMID- 30292776 TI - Using Mobile Technologies to Improve Women's Health. PMID- 30292777 TI - The role of genetics in stress effects on health and addiction. AB - Advances in stress research have yielded new insights into how stress exposure, in combination with genetics, can contribute to poor health outcomes. We review these topics with a special emphasis on early life stress and vulnerability to addiction. The direct effects of stress and our compensatory responses can modify our physiology and behavior during future stress episodes. These consequences can influence health, including an increased propensity for addiction. The relation between stress and health is not uniform across individuals. Some people succumb to stress-related disorders while others are resilient. Specific genetic polymorphisms affect how an individual appraises and responds to stress, potentially mediating the impact of stress on health. These genetic vulnerabilities can influence responses to the external environment, shape motivated behavior, and have an impact on health throughout life. PMID- 30292778 TI - Liposomal bupivacaine reduces narcotic use and time to flatus in a retrospective cohort of patients who underwent laparotomy. AB - INTRODUCTION: Sustained release liposomal bupivacaine (LB) is a new pain control option that can reduce opioid use after laparotomy, which is known to prolong ileus, length of stay. METHODS: Sixty-one consecutive patients undergoing laparotomy were treated with a standardized multi-modal therapy (MMT) consisting of IV tylenol, toradol, and morphine/dilaudid PCA. Thirty-one of those patients were additionally treated with LB infiltrated during fascial closure. Endpoints were opioid use, time to flatus, length of stay, and complications. RESULTS: Overall opioid use for 72 h was 78 mg of morphine for the MMT + LB group and 112 mg in the MMT control group (p = 0.04). During 0-24 h s PCA use was similar. However, during 24-48 h PCA use was decreased by 46% in the MMT + LB group (p = 0.038), and decreased by 55% during the 48-72 h period (p = 0.019). Time to flatus was decreased by 1.0 days in the MMT + LB group (p = 0.005). CONCLUSION: Use of LB in laparotomy patients decreases opioid use, time to flatus, and should be considered as a component of post-operative pain control. PMID- 30292779 TI - Views of the importance of psychiatric genetic research by potential volunteers from stakeholder groups. AB - Few studies have explored potential volunteers' attitudes toward genetic research. To address this gap in the literature, we developed an empirical project to document views held by individuals who may wish to enroll in genetic studies involving mental disorders. People living with mental illness, family members of people with mental illness, and community comparison volunteers were queried regarding their views on the importance of genetic research generally, in comparison with medical research, and in relation to 12 health conditions categorized in four types. T-tests and univariate and multivariate analysis of variance were used as appropriate. Participants expressed support for the importance of genetic research (mean = 9.43, scale = 1-10) and endorsed genetic research more highly compared with non-genetic medical research (mean = 9.43 vs. 8.69, P value = <0.001). The most highly endorsed genetic research was for cognitive disorders, followed by mental illness disorders, physical illness disorders, and addiction disorders (means = 8.88, 8.26, 8.16 and 7.55, respectively, P value = <0.001). Overall, this study provides evidence of strong endorsement of genetic research over non-genetic research by potential volunteers. PMID- 30292780 TI - Free thyroxine and thyroid-stimulating hormone in severe mental disorders: A naturalistic study with focus on antipsychotic medication. AB - BACKGROUND: Disturbances in thyroid function have been associated with use of psychotropic drugs, including antipsychotics. Still, the thyroid function in relation to commonly prescribed antipsychotic drugs and polypharmacy is not fully known. We investigated thyroid function associated with use of antipsychotics in patients with psychotic disorders compared with healthy controls. METHODS: We included 1345 patients and 989 healthy controls from the Thematically Organized Psychosis (TOP) study, recruiting participants between 18 and 65 years of age in the Oslo-area. All patients underwent a thorough clinical investigation and assessment of medication data. Thyroid function was determined from plasma levels of free thyroxin (fT4) and thyroid-stimulating hormone (TSH). Multiple linear regression analyses were performed to evaluate the association between thyroid parameters and use of antipsychotics, and monotherapy users of olanzapine, quetiapine, aripiprazole or risperidone (N = 473) were investigated separately. RESULTS: We found lower levels of fT4 (median 13.70 vs 14.00, p < 0.001) in patients compared to healthy controls, and a prevalence of 12.9% of previously undiagnosed deviant thyroid states in the patient group. Lower fT4 levels was associated with use of antipsychotics in general (p = 0.001), and quetiapine (p = 0.003) and olanzapine (p = 0.018) in particular, while the associations with TSH were non-significant. Using antipsychotics in combination with other psychotropic drugs, and with antidepressants in particular, was associated with lower fT4 level (p < 0.001) than use of antipsychotics alone. CONCLUSIONS: Our findings indicate an association between use of antipsychotics and lower fT4. Clinicians should be aware that patients using quetiapine, olanzapine or antipsychotics in psychotropic polypharmacy are especially at risk.

PMID- 30292782 TI - Missed Hepatitis B Birth Dose Vaccine Is a Risk Factor for Incomplete Vaccination at 18 and 24 Months. AB - OBJECTIVES: To determine whether missing the HepB birth dose vaccine is a risk factor for incomplete vaccination later in childhood. METHODS: This was a retrospective cohort study of infants born over one year at an academic medical center. The "not vaccinated at birth" group consisted of all infants who did not receive the HepB birth dose vaccine by seven days of life, while the "vaccinated at birth" group included infants who did receive the birth dose. The primary outcome was vaccination status at 18 months of age, determined from the state vaccination registry. RESULTS: Infants "not vaccinated at birth" had lower vaccination rates. At 18 months, 44% of the "vaccinated at birth" group received all recommended vaccines, compared with 23% of the "not vaccinated at birth" group (p<0.001); at 24 months, rates were 65% and 45%, respectively (p<0.001). Over 80% of the variability in vaccination completions were related to a single latent variable, which is most likely vaccine hesitancy/refusal. CONCLUSIONS: Infants who miss the HepB birth dose vaccine are at risk for under-immunization by 18 and 24 months of age. This suggests that parents likely form opinions about vaccines long before the birth of their child; therefore, efforts to influence attitudes must begin earlier. PMID- 30292783 TI - Similar distraction, but differential suppression, for faces and non-face objects: Evidence from behaviour and event-related potentials. AB - In everyday life we constantly experience distractions. Some distractors might be more distracting than others, for example the human face, which has been shown to be very efficient in attracting attention. Here, we employed the irrelevant distractor paradigm (Forster & Lavie, 2016) to measure behavioural and neural distraction by completely irrelevant faces or non-faces (cars), while participants performed a letter search task that was more (high-load) or less (low-load) demanding. Under low load conditions, faces and cars equally slowed responses on trials with distractors as compared to those without. In high load conditions, neither faces nor cars were distracting. However, event-related potentials revealed larger face-sensitive N170 responses to faces than cars under both load conditions, suggesting that early face-specific processing is present even under high load. A subsequent Pd modulation between 200 and 300 ms contralateral to the distractor position, which has been linked to the active top down suppression of lateral distractors (Hickey et al., 2009) was stronger for faces compared to cars. Overall, the EEG data indicate early face-specific processes to irrelevant faces irrespective of attentional load, coupled with stronger top-down suppression for faces. Together, these processes might reduce the influence of irrelevant face distractors on behavioural performance. PMID- 30292784 TI - The importance of precision to updating models of the sensory environment. AB - The existence and updating of "sensory beliefs" or internal models can be studied using auditory evoked potentials (AEPs) when there is some form of predictable pattern in sound. Internal models are proposed to enable predictions about the most likely next sound-activation-state leading to small AEPs to standard sounds matching model predictions, and larger AEPs to sound that deviate. Internal models are precision-weighted with the standard-deviant difference being largest when precision is high (variability is low). Here we expose how order-effects determine whether a change in variability impacts model-precision estimates. Thirty participants heard 3000 t (30 ms standard p = 0.90 and 60 ms deviant p = 0.10) that either moved from a more precise stimulus onset asymmetry (n = 15, first 1000 tones 500 ms +/- 10 ms) to a more variable one (n = 15, subsequent 2000 tones 500 ms +/- 200 ms) or from variable (first 1000 t) to more precise (subsequent 2000 t). AEPs were equivalent between groups for the first 1000 tones but differed dramatically in the face of timing changes. Where timing precision decreased, the standard-deviant difference was impervious to the change but where precision increased, the standard-deviant difference increased dramatically after the timing change signalling a transient increase in model precision that subsided over the final 1000 tones. The results support contemporary models proposing that updates to an active internal model will be a function of the quality of the evidence upon which it has been built and the information value of subsequent errors in improving the predictive success of the active model. PMID- 30292785 TI - The Neurobiology of Reduced Autobiographical Memory Specificity. AB - There has been a recent growth in investigations into the neural mechanisms underlying the problems recalling specific autobiographical events that are a core feature of emotional disorders. In this review we provide the first synthesis of this literature, taking into account brain as well as cognitive mechanisms. We suggest that these problems are driven by idiosyncratic activation in areas of the brain associated with assigning salience and self-relevance to emotional memories. Other areas associated with inhibiting distraction and constructing vivid memory representations are also important. Each of these mechanisms may work independently or in concert with one another. Importantly, this interaction between mechanisms may differ between diagnostic and demographic groups such that similar problems in specificity may be characterised by different mechanisms. Given this challenge, neuroimaging may prove useful in identifying patient-specific biomarkers for interventions. PMID- 30292786 TI - Loss of Tbx3 in murine neural crest reduces enteric glia and causes cleft palate, but does not influence heart development or bowel transit. AB - Transcription factors that coordinate migration, differentiation or proliferation of enteric nervous system (ENS) precursors are not well defined. To identify novel transcriptional regulators of ENS development, we performed microarray analysis at embryonic day (E) 17.5 and identified many genes that were enriched in the ENS compared to other bowel cells. We decided to investigate the T-box transcription factor Tbx3, which is prominently expressed in developing and mature ENS. Haploinsufficiency for TBX3 causes ulnar-mammary syndrome (UMS) in humans, a multi-organ system disorder. TBX3 also regulates several genes known to be important for ENS development. To test the hypothesis that Tbx3 is important for ENS development or function, we inactivated Tbx3 in all neural crest derivatives, including ENS progenitors using Wnt1-Cre and a floxed Tbx3 allele. Tbx3 fl/fl; Wnt1-Cre conditional mutant mice die shortly after birth with cleft palate and difficulty feeding. The ENS of mutants was well-organized with a normal density of enteric neurons and nerve fiber bundles, but small bowel glial cell density was reduced. Despite this, bowel motility appeared normal. Furthermore, although Tbx3 is expressed in cardiac neural crest, Tbx3 fl/fl; Wnt1 Cre mice had structurally normal hearts. Thus, loss of Tbx3 within neural crest has selective effects on Tbx3-expressing neural crest derivatives. PMID- 30292787 TI - TRPV1 modulates morphine self-administration via activation of the CaMKII-CREB pathway in the nucleus accumbens. AB - Opioid addiction is a growing problem for public health, and opioids have correspondingly become more heavily regulated over time. We have previously shown that TRPV1 plays a critical role in morphine addiction using a self administration paradigm in rats, and the current study evaluates the effects of the TRPV1 signaling pathway on morphine self-administration (SA). We found that treatment with a selective TRPV1 antagonist, SB366791, significantly decreased the morphine SA-induced activation of Ca2+/calmodulin-dependent protein kinase II (CaMKII), Akt and the cAMP response element binding protein (CREB) in the nucleus accumbens (NAc). In addition, phospho-PKA and phospho-PKC expression levels were significantly increased in the NAc of the morphine-SA groups, regardless of SB366791 treatment. Finally, local microinjection of SB366791 into the NAc significantly suppressed the maintenance of morphine SA. Taken together, our findings highlight that TRPV1 plays an important role in morphine addiction, likely via activation of the CaMKII-CREB pathway in the NAc. PMID- 30292788 TI - Multiscale heterogeneity in filamentous microbes. AB - Microbial cells within clonal populations can display different morphologies or carry out different tasks. This heterogeneity is beneficial at the population level and allows microbes to spread risk or separate incompatible activities. Heterogeneity is also evident in filamentous bacteria and fungi, which form mycelial networks consisting of interconnected hyphae. Here, heterogeneity is observed between clonal mycelial particles, between different zones of colonies, between adjacent hyphae and even between adjacent compartments of individual hyphae. In this review, we compare this multiscale heterogeneity in filamentous bacteria and fungi and discuss the underlying mechanisms. These mechanisms might provide targets to improve the exploitability of these organisms as cell factories in the biotech sector.

PMID- 30292791 TI - CGPS: A machine learning-based approach integrating multiple gene set analysis tools for better prioritization of biologically relevant pathways. AB - Gene set enrichment (GSE) analyses play an important role in the interpretation of large-scale transcriptome datasets. Multiple GSE tools can be integrated into a single method as obtaining optimal results is challenging due to the plethora of GSE tools and their discrepant performances. Several existing ensemble methods lead to different scores in sorting pathways as integrated results; furthermore, it is difficult for users to choose a single ensemble score to obtain optimal final results. Here, we develop an ensemble method using a machine learning approach called Combined Gene set analysis incorporating Prioritization and Sensitivity (CGPS) that integrates the results provided by nine prominent GSE tools into a single ensemble score (R score) to sort pathways as integrated results. Moreover, to the best of our knowledge, CGPS is the first GSE ensemble method built based on a priori knowledge of pathways and phenotypes. Compared with 10 widely used individual methods and five types of ensemble scores from two ensemble methods, we demonstrate that sorting pathways based on the R score can better prioritize relevant pathways, as established by an evaluation of 120 simulated datasets and 45 real datasets. Additionally, CGPS is applied to expression data involving the drug panobinostat, which is an anticancer treatment against multiple myeloma. The results identify cell processes associated with cancer, such as the p53 signaling pathway (hsa04115); by contrast, according to two ensemble methods (EnrichmentBrowser and EGSEA), this pathway has a rank higher than 20, which may cause users to miss the pathway in their analyses. We show that this method, which is based on a priori knowledge, can capture valuable biological information from numerous types of gene set collections, such as KEGG pathways, GO terms, Reactome, and BioCarta. CGPS is publicly available as a standalone source code at ftp://ftp.cbi.pku.edu.cn/pub/CGPS_download/cgps 1.0.0.tar.gz. PMID- 30292792 TI - Impact of pretransplant CMV-specific T-cell immune response in the control of CMV infection after solid organ transplantation: a prospective cohort study. AB - INTRODUCTION: Although solid organ transplant (SOT) recipients with pretransplant serology for cytomegalovirus (CMV-R+) are considered at intermediate risk for CMV infection post transplantation, CMV infection remains a major cause of morbidity in this population. We prospectively characterized whether having pretransplant CMV-specific cellular immunity is independently associated with controlling infection after transplantation in R + SOT recipients. METHODS: A prospective cohort of consecutive R + SOT recipients that received pre-emptive treatment for CMV infection was monitored after transplantation and variables were recorded during the follow-up. The cytomegalovirus-specific T-cell immune response was characterized by intracellular cytokine staining and viral loads determined using real-time PCR. RESULTS: One hundred and thirty-five R + SOT recipients were included (67 kidney, 64 liver, four liver-kidney). Only one-third of the patients (42; 31.85%) had CMV-specific T-cell immunity (CD8+CD69+INF-gamma+ T cells >0.25%) before transplantation. Patients with negative pretransplant immunity had more CMV infection (49, 52.7% vs. 15, 35.7%; p 0.07) and received more antiviral therapy than those with immunity (32, 34.4% vs. 6, 14.3%, p 0.016). Having CMV specific immunity was an independent factor for protection from developing viraemia >=2000 IU/mL (OR 0.276, 95% CI 0.105-0.725, p < 0.01) and lower administration of treatment (OR 0.398, 95% CI 0.175-0.905, p 0.028). Only patients with no pretransplant CMV-specific T-cell response were diagnosed with CMV-disease (8, 8.6% vs. 0, 0%, p 0.05). DISCUSSION: Our results show that having a pretransplant CMV specific T-cell response may be associated with a lower rate of CMV viraemia and less antiviral treatment after transplantation; however, more prospective studies are needed to confirm these findings. PMID- 30292793 TI - Characteristics Associated With High-Impact Pain in People With Temporomandibular Disorder: A Cross-Sectional Study. AB - High-impact (disabling) pain diminishes the quality of life and increases health care costs. The purpose of this study was to identify the variables that distinguish between high- and low-impact pain among individuals with painful temporomandibular disorder (TMD). Community-dwelling adults (N = 846) with chronic TMD completed standardized questionnaires that assessed the following: 1) sociodemographic characteristics, 2) psychological distress, 3) clinical pain, and 4) experimental pain. We used high-impact pain, classified using the Graded Chronic Pain Scale, as the dependent variable in logistic regression modeling to evaluate the contribution of variables from each domain. Cross-validated area under the receiver operating characteristic curve (AUC) quantified model discrimination. One-third of the participants had high-impact pain. Sociodemographic variables discriminated weakly between low- and high-impact pain (AUC = .61, 95% confidence interval [CI] = 0.57, 0.65), with the exception of race. An 18-variable model encompassing all 4 domains had good discrimination (AUC = 0.79, 95% CI = 0.75, 0.82), as did a simplified model (sociodemographic variables plus catastrophizing, jaw limitation, and number of painful body sites) (AUC = 0.79, 95% CI = 0.76, 0.82). Duration of pain, sex, and experimental pain testing results were not associated. The characteristics that discriminated most effectively between people with low- and high-impact TMD pain included clinical pain features and the ability to cope with pain. PERSPECTIVE: This article presents the results of a multivariable model designed to discriminate between people with high- and low-impact pain in a community-based sample of people with painful chronic TMD. The findings emphasize the importance of catastrophizing, jaw limitation, and painful body sites associated with pain-related impact. PMID- 30292794 TI - Drug delivery to the eye anterior chamber by intraocular lenses: An in vivo concentration estimation model. AB - Drug loaded intraocular lenses have been proposed as an alternative to the conventional post-cataract removal prophylaxis through topical drug administration, since the drug or combination of drugs released from the lenses are delivered directly to the target site. In this work, a mathematical model to estimate the concentration of drug released from such lenses in the eye aqueous humor was developed. To attain these estimated concentration profiles, partition and effective diffusivity coefficients for the specific lens material were obtained from standard in vitro release experiments. The model was validated by comparing the predicted aqueous humor concentrations with those obtained in in vivo studies where hydrophilic acrylic intraocular lens loaded with an antibiotic (moxifloxacin) were implanted in rabbits. Subsequently, other partition and effective diffusivity values were determined for levofloxacin, diclofenac and ketorolac in the same hydrophilic acrylic and in a second material, a silicone hydrogel. Predicted drug concentrations in the aqueous humor allowed an initial screening and evaluation of the most promising system for post-cataract removal prophylaxis, with the hydrophilic acrylic material presenting promising results, especially for moxifloxacin and diclofenac controlled release.

AB - Antibody selection for antibody-drug conjugates (ADCs) has traditionally depended on its internalization into the target cell, although ADC efficacy also relies on recycling of the receptor-ADC complex, endo-lysosomal trafficking, and subsequent linker/antibody proteolysis. In this study, we observed that a bispecific anti murine platelet-derived growth factor receptor beta (mPDGFRbeta) x cotinine single-chain variable fragment (scFv)-kappa constant region (Ckappa)-scFv fusion protein and cotinine-duocarmycin can form an ADC-like complex to induce cytotoxicity against mPDGFRbeta expressing cells. Multiple anti-mPDGFRbeta antibody candidates can be produced in this bispecific scFv-Ckappa-scFv fusion protein format and tested for their ability to deliver cotinine-conjugated cytotoxic drugs, thus providing an improved approach for antibody selection in ADC development. PMID- 30292796 TI - Shedding light on microRNA function via microscopy-based screening. AB - MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally modulate gene expression and orchestrate a wide range of biological and pathological processes. The use of high-throughput screening technologies, in particular microscopy-based screenings (also known as high-content screenings), coupled with genome-wide libraries for modulation of miRNA levels, allow for comprehensive functional analysis of each member of the miRNome in different phenotypic cell based assays. The wealth of information obtained from such screenings spans across various fields of research, including cancer, cardiovascular, cell reprogramming, and infection biology. Here, we provide an overview of the rationale for performing screenings using synthetic libraries of miRNA mimics and inhibitors, and of the microscopy-based miRNA screenings performed to date. Moreover, a list of resources available for such endeavor is provided. Finally, we describe a detailed procedure for a case study where microscopy-based screening using a library of miRNA mimics was performed to identify miRNAs that control infection of epithelial cells by the bacterial pathogen Salmonella. The methodologies described here can be easily adapted for screenings addressing other biological questions.

AB - Landscape-scale vegetation stripes (tiger bush) observed on the gentle slopes of semi-arid regions are useful indicators of future ecosystem degradation and catastrophic shifts towards desert. Mathematical models like the Klausmeier model a set of coupled partial differential equations describing vegetation and water densities in space and time-are central to understanding their formation and development. One assumption made for mathematical simplicity is the local dispersal of seeds via a diffusion term. In fact, a large amount of work focuses on fitting dispersal 'kernels', probability density functions for seed dispersal distance, to empirical data of different species and modes of dispersal. In this paper, we address this discrepancy by analysing an extended Klausmeier model that includes long-distance seed dispersal via a non-local convolution term in place of diffusion, and assessing its effect on the resilience of striped patterns. Many authors report a slow uphill migration of stripes; but others report no detectable migration speed. We show that long-distance seed dispersal permits the formation of patterns with a very slow (possibly undetectable) migration speed, and even stationary patterns which could explain the inconsistencies in the empirical data. In general, we show that the resilience of patterns to reduced rainfall may vary significantly depending on the rate of seed dispersal and the width of the dispersal kernel, and compare a selection of ecologically relevant kernels to examine the variation in pattern resilience.

AB - Adenocarcinoma is the most frequent cancer affecting the prostate walnut-size gland in the male reproductive system. Such cancer may have a very slow progression or may be associated with a "dark prognosis" when tumor cells are spreading very quickly. Prostate cancers have the particular properties to be marked by the level of prostate specific antigen (PSA) in blood which allows to follow its evolution. At least in its first phase, prostate adenocarcinoma is most often hormone-dependent and, consequently, hormone therapy is a possible treatment. Since few years, hormone therapy started to be provided intermittently for improving patient's quality of life. Today, durations of on- and off treatment periods are still chosen empirically, most likely explaining why there is no clear benefit from the survival point of view. We therefore developed a model for describing the interaction between the tumor environment, the PSA produced by hormone-dependent and hormone-independent tumor cells, respectively, and the level of androgens. Model parameters were identified using a genetic algorithm applied to the PSA time series measured in a few patients who initially received prostatectomy and were then treated by intermittent hormone therapy (LHRH analogs and anti-androgen). The measured PSA time series is quite correctly reproduced by free runs over the whole follow-up. Model parameter values allow for distinguishing different types of patient (age and Gleason score) meaning that the model can be individualized. We thus showed that the long-term evolution of the cancer can be affected by durations of on- and off-treatment periods. PMID- 30292802 TI - Prediction of neurological outcomes following the return of spontaneous circulation in patients with out-of-hospital cardiac arrest: Retrospective fast and-frugal tree analysis. AB - AIM: Although various quantitative methods have been developed for predicting neurological prognosis in patients with out-of-hospital cardiac arrest (OHCA), they are too complex for use in clinical practice. We aimed to develop a simple decision rule for predicting neurological outcomes following the return of spontaneous circulation (ROSC) in patients with OHCA using fast-and-frugal tree (FFT) analysis. METHODS: We performed a retrospective analysis of prospectively collected data archived in a multi-centre registry. Good neurological outcomes were defined as cerebral performance category (CPC) values of 1 or 2 at 28-day. Variables used for FFT analysis included age, sex, witnessed cardiac arrest, bystander cardiopulmonary resuscitation, initial shockable rhythm, prehospital defibrillation, prehospital ROSC, no flow time, low flow time, cause of arrest (cardiac or non-cardiac), pupillary light reflex, and Glasgow Coma Scale score after ROSC. RESULTS: Among the 456 patients enrolled, 86 (18.9%) experienced good neurological outcomes. Prehospital ROSC (true = good), prompt or sluggish light reflex response after ROSC (true = good), and presumed cardiac cause (true = good, false = poor) were selected as nodes for the decision tree. Sensitivity, specificity, positive predictive value, and negative predictive value of the decision tree for predicting good neurological outcomes were 100% (42/42), 64.0% (119/186), 38.5% (42/109), and 100% (119/119) in the training set and 95.5% (42/44), 57.6% (106/184), 35.0% (42/120), and 98.1% (106/108) in the test set, respectively. CONCLUSION: A simple decision rule developed via FFT analysis can aid clinicians in predicting neurological outcomes following ROSC in patients with OHCA. PMID- 30292803 TI - Global resuscitation alliance consensus recommendations for developing emergency care systems: Reducing perinatal mortality. AB - Perinatal and neonatal deaths account for an increasing proportion of deaths under 5 years old. We present essential elements to reduce perinatal mortality, barriers to establishing these elements, and the role of developing emergency care systems. Essential elements for prompt perinatal and postnatal care are categorised based on care-seeking behaviours, access to a primary care facility and for the severely ill, access to advanced neonatal care. The role of emergency care systems is key to overcoming obstacles currently faced in countries with high perinatal and neonatal mortality rates. PMID- 30292804 TI - Identification of an anti-lipopolysaccharide factor AV-R isoform (LvALF AV-R) related to Vp_PirAB-like toxin resistance in Litopenaeus vannamei. AB - Acute hepatopancreatic necrosis disease (AHPND) is a shrimp farming disease, caused by the pathogenic Vibrio parahaemolyticus carrying a plasmid encoding Vp_PirAB-like toxins. Formalin-killed cells of V. parahaemolyticus AHPND-causing strain D6 (FKC-VpD6) were used to select Vp_PirAB-like toxin-resistant Litopenaeus vannamei by oral administration. Stomach and hepatopancreas tissues of shrimps that survived for one week were subjected to RNA sequencing. Differentially expressed genes (DEGs) between surviving shrimp, AHPND-infected shrimp, and normal shrimp were identified. The expressions of 10 DEGs were validated by qPCR. Only one gene (a gene homologous to L. vannamei anti lipopolysaccharide factor AV-R isoform (LvALF AV-R)) was expressed significantly more strongly in the hepatopancreas of surviving shrimp than in the other groups. Significantly higher expression of LvALF AV-R was also observed in shrimp that survived two other trials of FKC-VpD6 selection. Recombinant ALF AV-R bound to LPS, PGN, Gram-negative bacteria, and some Gram-positive bacteria in ELISAs. ALF AV-R recombinant protein did not interact with native Vp_PirAB-like toxin in an ELISA or a Far-Western blot. For L. vannamei orally fed ALF AV-R protein for 3 days, the survival rate following challenge with VpD6-immersion was not significantly different from that of shrimp fed two control diets. These results suggest that LvALF AV-R expression was induced in the hepatopancreas of shrimp in response to the presence of Vp_PirAB-like toxin, although other factors might also be involved in the resistance mechanism. PMID- 30292805 TI - Thymosins participate in antibacterial immunity of kuruma shrimp, Marsupenaeus japonicus. AB - Thymosins beta are actin-binding proteins that play a variety of different functions in inflammatory responses, wound healing, cell migration, angiogenesis, and stem cell recruitment and differentiation. In crayfish, thymosins participate in antiviral immunology. However, the roles of thymosin during bacterial infection in shrimp remain unclear. In the present study, four thymosins were identified from kuruma shrimp, Marsupenaeus japonicus, and named as Mjthymosin2, Mjthymosin3, Mjthymosin4, and Mjthymosin5 according the number of their thymosin beta actin-binding motifs. Mjthymosin3 was selected for further study because its expression level was the highest in hemocytes. Expression analysis showed that Mjthymosin3 was upregulated in hemocytes after challenged by Vibrio anguillarum or Staphylococcus aureus. The recombinant Mjthymosin3 protein could inhibit the growth of certain bacteria in an in vitro antibacterial test. Mjthymosins could facilitate external bacterial clearance in shrimp, and were beneficial to shrimp survival post V. anguillarum or S. aureus infection. The results suggested that Mjthymosins played important roles in the antibacterial immune response of kuruma shrimp. PMID- 30292806 TI - Expression and purification of a new lectin from mussel Mytilus trossulus. AB - The gene of mtl from the mussel Mytilus trossulus was cloned into pET-40b(+) expression vector. After expression in E. coli using designed MX-medium an instable soluble form of MTL was obtained. The developed isolation method of the recombinant protein in "semi-denatured" conditions allowed obtaining an active soluble form of the homogenous lectin from the mussel M. trossulus (r-MTL). Both of the lectins had similar antigenic and spatial structures. PMID- 30292807 TI - High-yield production of spider short-chain insecticidal neurotoxin Tx4(6-1) in Pichia pastoris and bioactivity assays in vivo. AB - Short-chain insecticidal neurotoxin Tx4(6-1) from the spider Phoneutria nigriventer can be prepared by reversed-phase high-performance liquid chromatography (HPLC) fractionation of PhTx4, but this is difficult and represents an obstacle preventing analyses of its insecticidal activity against agricultural insect pests. Herein, we performed secretory expression of recombinant Tx4(6-1) using Pichia pastoris strain X33 as the host, and screened transformants using enzyme-linked immunosorbent assay (ELISA). In flasks, ~5 mg/l rTx4(6-1) was expressed as a secreted protein following induction with methanol, and this was increased to 45 mg/l rTx4(6-1) in a fed-batch reactor. Approximately 4 mg of high-purity rTx4(6-1) was purified from a 400 ml fed-batch culture supernatant by Ni+-nitriloacetic acid affinity chromatography, followed by carboxymethyl (CM) sepharose ion-exchange chromatography. Purified rTx4(6-1) was determined by mass spectrometry (MS) analysis, revealing a molecular weight (MW) of 7660.5 Da, larger than the expected size due to O-linked glycosylation. Insect bioactivity tests of rTx4(6-1)-treated fifth-instar silkworm larvae (Bombyx mori Linnaeus) showed neurotoxin symptoms such as contraction paralysis, abdominal contraction, and mouth movement syndrome, with a half lethal dose at 12 h post injection of ~4.5-8.5 MUg/g body weight. Dietary toxicity was not observed in silkworm larvae. PMID- 30292808 TI - Alterations in Resting-State Networks Following In Utero Selective Serotonin Reuptake Inhibitor Exposure in the Neonatal Brain. AB - BACKGROUND: Selective serotonin reuptake inhibitors (SSRIs) are commonly used to treat depression during pregnancy. SSRIs cross the placenta, inhibit serotonin reuptake, and thereby are thought to alter central fetal serotonin signaling. Both prenatal maternal mood disturbances and in utero SSRI exposure have been associated with altered fetal and infant behavior. Resting-state functional magnetic resonance imaging has identified resting-state networks (RSNs) in newborns, reflecting functional capacity of auditory and visual networks and providing opportunities to examine early experiences effects on neurodevelopment. We sought to examine the effect of in utero SSRI exposure on neonatal RSN functional organization. We hypothesized that prenatal SSRI exposure would be associated with alterations in neonatal RSNs compared with healthy control infants and infants exposed to mothers with depression. METHODS: Clinician-rated Hamilton Depression Rating Scale and self-reported Pregnancy Experiences Scale were completed during the third trimester. Control (n = 17), maternal depression exposed (Hamilton Depression Rating Scale >=8 without SSRI exposure, n = 16), and SSRI-exposed (n = 20) 6-day-old neonates underwent resting-state functional magnetic resonance imaging. Independent component analysis was used as a data driven approach to extract 22 RSNs. RESULTS: SSRI-exposed neonates had higher connectivity in a putative auditory RSN compared with depressed-only (p = .01) and control (p = .02) infants (corrected for multiple comparisons), controlling for sex, age at the magnetic resonance imaging, and Pregnancy Experiences Scale score. CONCLUSIONS: Hyperconnectivity in auditory RSN in neonates with in utero SSRI exposure relative to neonates of depressed but not pharmacologically treated mothers and control infants may offer an insight into the functional organization origins of shifts in language perception and altered language development, previously reported in infants and children with prenatal SSRI exposure. PMID- 30292809 TI - Preschool Executive Function Predicts Childhood Resting-State Functional Connectivity and Attention-Deficit/Hyperactivity Disorder and Depression. AB - BACKGROUND: Measures of executive function (EF), such as the Behavior Rating Inventory of Executive Function, distinguish children with attention deficit/hyperactivity disorder (ADHD) from control subjects, but less work has examined relationships to depression or brain network organization. This study examined whether early childhood EF predicted new onset or worsening of ADHD and/or depression and examined how early childhood EF related to functional connectivity of brain networks at school age. METHODS: Participants included 247 children who were enrolled at 3 to 6 years of age from a prospective study of emotion development. The Behavior Rating Inventory of Executive Function Global Executive Composite score was used as the measure of EF in early childhood to predict ADHD and depression diagnoses and symptoms across school age. Resting state functional magnetic resonance imaging network analyses examined global efficiency in the frontoparietal, cingulo-opercular, salience, and default mode networks and six "hub" seed regions selected to examine between-network connectivity. RESULTS: Early childhood EF predicted new onset and worsening of ADHD and depression symptoms across school age. Greater EF deficits in preschool predicted increased global efficiency in the salience network and altered connectivity with four regions for the dorsal anterior cingulate cortex hub and one region with the insula hub at school age. This altered connectivity was related to increasing ADHD and depression symptoms. CONCLUSIONS: Early executive deficits may be an early common liability for risk of developing ADHD and/or depression and were associated with altered functional connectivity in networks and hub regions relevant to executive processes. Future work could help clarify whether specific EF deficits are implicated in the development of both disorders. PMID- 30292810 TI - Post rapid freezing growth of Antarctic strain of Heterococcus sp. monitored by cell viability and chlorophyll fluorescence. AB - The soil microalgae of the genus Heterococcus are found in cold environments and have been reported for the terrestrial ecosystems of several Sub-Antarctic and Antarctic Islands. This study focused on resistance of Heterococcus sp. to sub zero temperature. Heterococcus sp. was isolated from soil samples from James Ross Island, Antarctica. Culture of Heterococcus sp. grown in liquid medium were used to study ribitol effects at sub-zero temperatures on the species resistance to rapid freezing (RF, immersion of a sample into liquid nitrogen) and consequent cultivation on agar. Before the experiment, Heterococcus sp. was cultured in liquid medium for 11 months and then treated in ribitol concentrations of 32 or 50 mM for 2 h. Then, 1 ml samples were frozen to -196 degrees C in liquid nitrogen (day 0) and inoculated on BBM agar after thawing. Number of living and dead cells was evaluated and the cell viability (Pnu) was calculated repeatedly using the optical microscopy approach. The addition of ribitol caused a noticable increase in Pnu on days 9, 12, 14 (with a Pnu of 25-45% in ribitol-treated samples compared to 10% in the untreated control). In the following period (d 16 19), the positive effect of ribitol on Pnu was less pronounced but still statistically significant. To evaluate the negative effects of RF on chlorophyll fluorescence parameters, the potential yield of photochemical reactions in PS II (FV/FM), and the effective quantum yield of photochemical reactions in PS II (FPSII) were measured immediately before and after RF. Consequently, FV/FM and FPSII of agar inoculates were measured repeatedly for 30 d cultivation in 3 d interval. Both the 32 and the 50 mM addition of ribitol caused earlier detection of the parameters (d 16) compared to the control measurements (d 23) as well as reaching the maximum values of the chlorophyll fluorescence parameters earlier (d 23 in ribitol-treated samples compared to d 25 in control samples). Heterococcus sp. proved to be a species resistant to rapid freezing. The ability may help the species to survive in harsh Antarctic environments typified by rapid fluctuations in temperature that may bring a rapid freezing of the alga. PMID- 30292811 TI - Cryopreservation of human umbilical vein and porcine corneal endothelial cell monolayers. AB - Cryopreservation of endothelium is one of the major challenges in the cryopreservation of complex tissues. Human umbilical vein endothelial cells (HUVECs) in suspension are available commercially and recently their post-thaw cell membrane integrity was significantly improved by cryopreservation in 5% dimethyl sulfoxide (Me2SO) and 6% hydroxyethyl starch (HES). However, cryopreservation of cells in monolayers has been elusive. The exact mechanisms of damage during cell monolayer cryopreservation are still under investigation. Here, we show that a combination of different factors contribute to significant progress in cryopreservation of endothelial monolayers. The addition of 2% chondroitin sulfate to 5% Me2SO and 6% HES and cooling at 0.2 or 1 degrees C/min led to high membrane integrity (97.3 +/- 3.2%) immediately after thaw when HUVECs were cultured on a substrate with a coefficient of thermal expansion similar to that of ice. The optimized cryopreservation protocol was applied to monolayers of primary porcine corneal endothelial cells, and resulted in high post-thaw viability (95.9 +/- 3.7% membrane integrity) with metabolic activity 12 h post thaw comparable to unfrozen control. PMID- 30292812 TI - Hypothermic pulsatile perfusion of human pancreas: Preliminary technical feasibility study based on histology. AB - BACKGROUND: There are currently two approaches to hypothermic preservation for most solid organs: static or dynamic. Cold storage is the main method used for static storage (SS), while hypothermic pulsatile perfusion (HPP) and other machine perfusion-based methods, such as normothermic machine perfusion and oxygen persufflation, are the methods used for dynamic preservation. HPP is currently approved for kidney transplantation. METHODS: We evaluated, for the first time, the feasibility of HPP on 11 human pancreases contraindicated for clinical transplantation because of advanced age and/or history of severe alcoholism and/or abnormal laboratory tests. Two pancreases were used as SS controls, pancreas splitting was performed on 2 other pancreases for SS and HPP and 7 pancreases were tested for HPP. HPP preservation lasted 24 h at 25 mmHg. Resistance index was continuously monitored and pancreas and duodenum histology was evaluated every 6 h. RESULTS: The main finding was the complete absence of edema of the pancreas and duodenum at all time-points during HPP. Insulin, glucagon and somatostatin staining was normal. Resistance index decreased during the first 12 h and remained stable thereafter. CONCLUSION: 24 h hypothermic pulsatile perfusion of marginal human pancreas-duodenum organs was feasible with no deleterious parenchymal effect. These observations encourage us to further develop this technique and evaluate the safety of HPP after clinical transplantation. PMID- 30292813 TI - Brain functional and effective connectivity underlying the information processing speed assessed by the Symbol Digit Modalities Test. AB - Delayed Information Processing Speed (IPS) often underlies attention deficits and is particularly evident in patients with traumatic brain injury, Parkinson's disease, depression, dementia, and multiple sclerosis. Therefore, it is of interest to determine the brain network that is responsible for such essential cognitive function to understand IPS deficits and to develop effective rehabilitation programs. We assessed brain functional connectivity and effective connectivity during the performance of an adapted version of the Symbol Digit Modalities Test. Using dynamic causal modeling, we focused on obtaining a network model for IPS function in healthy subjects. Sixteen right-handed volunteers (seven women, age: 29.7 +/- 5.0 years) were included in the study after giving written consent for participating. Functional magnetic resonance images were acquired in a 3T scanner. According to our results, two systems interact during the IPS task performance. One is formed by frontoparietal and fronto-occipital networks, related to the control of goal-directed (top-down) selection for stimuli and response, while the second is composed of the temporoparietal and inferior frontal cortices, which are associated with stimulus-driven attention in the brain. Additionally, the default-mode network showed a significant correlation with networks positively associated with the task, mainly those related to visual detection and processing, indicating its relevant role in functional integration involving IPS. Therefore, an IPS-related network was proposed through a methodology that may be useful for future studies considering other cognitive functions and tasks, clinical groups, and longitudinal assessments. PMID- 30292814 TI - Dynamic 23Na MRI - A non-invasive window on neuroglial-vascular mechanisms underlying brain function. AB - A novel magnetic resonance imaging (MRI) acquisition and reconstruction method for obtaining a series of dynamic sodium 23Na-MRI acquisitions was designed to non-invasively assess the signal variations of brain sodium during a hand motor task in 14 healthy human volunteers on an ultra high field (7T) MR scanner. Regions undergoing activation and deactivation were identified with reference to conventional task-related BOLD functional MRI (fMRI). Activation observed in the left central regions, the supplementary motor areas and the left cerebellum induced an increase in the sodium signal observed at ultra short echo time and a decrease in the 23Na signal observed at long echo time. Based on a simple model of two distinct sodium pools (namely, restricted and mobile sodium), the ultra short echo time measures the totality of sodium whereas the long echo time is mainly sensitive to mobile sodium. This activation pattern is consistent with previously described processes related to an influx of Na+ into the intracellular compartments and a moderate increase in the cerebral blood volume (CBV). In contrast, deactivation observed in the right central regions ipsilateral to the movement, the precuneus and the left cerebellum induced a slight decrease in sodium signal at ultra short echo time and an increase of sodium signal at longer echo times. This inhibitory pattern is compatible with a slight decrease in CBV and an efflux of intracellular Na+ to the extracellular compartments that may reflect neural dendritic spine and astrocytic shrinkage, and an increase of sodium in the extracellular fraction. In conclusion, cerebral dynamic 23Na MRI experiments can provide access to the ionic transients following a functional task occurring within the neuro-glial-vascular ensemble. This has the potential to open up a novel non-invasive window on the mechanisms underlying brain function. PMID- 30292815 TI - On the scaling behavior of water diffusion in human brain white matter. AB - Development of therapies for neurological disorders depends on our ability to non invasively diagnose and monitor the progression of underlying pathologies at the cellular level. Physics and physiology limit the resolution of human MRI to be orders of magnitude coarser than cell dimensions. Here we identify and quantify the MRI signal coming from within micrometer-thin axons in human white matter tracts in vivo, by utilizing the sensitivity of diffusion MRI to Brownian motion of water molecules restricted by cell walls. We study a specific power-law scaling of the diffusion MRI signal with the diffusion weighting, predicted for water confined to narrow axons, and quantify axonal water fraction and orientation dispersion. PMID- 30292816 TI - Proteomic and metabolomic approaches in the search for biomarkers in chronic kidney disease. AB - Chronic kidney disease (CKD) is an aging-related disorder that represents a major global public health burden. Current biochemical biomarkers, such as serum creatinine and urinary albumin, have important limitations when used to identify the earliest indication of CKD or in tracking the progression to more advanced CKD. These issues underline the importance of finding and testing new molecular biomarkers that are capable of successfully meeting this clinical need. The measurement of changes in nature and/or levels of proteins and metabolites in biological samples from patients provide insights into pathophysiological processes. Proteomic and metabolomic techniques provide opportunities to record dynamic chemical signatures in patients over time. This review article presents an overview of the recent developments in the fields of metabolomics and proteomics in relation to CKD. Among the many different proteomic biomarkers proposed, there is particular interest in the CKD273 classifier, a urinary proteome biomarker reported to predict CKD progression and with implementation potential. Other individual non-invasive peptidomic biomarkers that are potentially relevant for CKD detection include type 1 collagen, uromodulin and mucin-1. Despite the limited sample sizes and variability of the metabolomics studies, some metabolites such as trimethylamine N-oxide, kynurenine and citrulline stand out as potential biomarkers in CKD. PMID- 30292817 TI - Associations of dietary protein intake with bone mineral density: An observational study in 70,215 UK Biobank participants. AB - PURPOSE: Adequate dietary protein intake is important for the maintenance of bone health; however, data in this area is ambiguous with some suggestion that high protein intake can have deleterious effects on bone health. The aim of the current study was to explore the associations of protein intake with bone mineral density (BMD). METHODS: We used baseline data from the UK Biobank (participants aged 40-69 years) to examine the association of protein intake with BMD (measured by ultrasound). These associations were examined, in women (n = 39,066) and men (n = 31,149), after adjustment for socio-demographic and lifestyle confounders and co-morbidities. RESULTS: Protein intake was positively and linearly associated with BMD in women (beta-coefficient 0.010 [95% CI 0.005; 0.015, p < 0.0001]) and men (beta-coefficient 0.008 [95% CI 0.000; 0.015, p = 0.044]); per 1.0 g/kg/day increment in protein intake, independently of socio-demographics, dietary factors and physical activity. CONCLUSIONS: The current data have demonstrated that higher protein intakes are positively associated with BMD in both men and women. This indicates that higher protein intakes may be beneficial for both men and women. PMID- 30292818 TI - Denosumab effects on bone density and turnover in postmenopausal women with low bone mass with or without previous treatment. AB - PURPOSE: Prior osteoporosis therapies may affect the skeletal response to denosumab. We compared the effect of denosumab (60 mg every 6 months for 12 months) on bone mineral density and bone metabolism parameters in postmenopausal women with low bone mass who were either treatment-naive (n = 30), or previously treated either with zoledronic acid (n = 30), or teriparatide (n = 22). METHODS: We assessed lumbar spine bone mineral density (BMD) and measured serum concentrations of the bone turnover markers pro-collagen type 1 N-terminal propeptide (PINP) and C-terminal-cross-linking telopeptide of type 1 collagen (CTX), as well as sclerostin, dickkopf-1 (Dkk-1), and myostatin. RESULTS: Lumbar spine BMD increased equivalently in all three groups after 12 months of denosumab compared to baseline (p < 0.001). Serum PINP and CTX decreased significantly with denosumab in pre-treated women reaching the same nadir levels as in treatment naive patients (p < 0.001). Women pre-treated with teriparatide displayed lower baseline myostatin concentrations as compared to the other two groups (p < 0.001). Changes in lumbar spine BMD in teriparatide pre-treated women correlated with changes in bone turnover markers and myostatin. CONCLUSIONS: Denosumab induced similar increases in lumbar spine BMD in treatment-naive and pre-treated patients and suppressed serum PINP and CTX to the same levels regardless of prior treatments. In teriparatide pre-treated patients the magnitude of change in bone turnover markers is associated with BMD response. PMID- 30292819 TI - Biochemical and Structural Characterization of TesA, a Major Thioesterase Required for Outer-Envelope Lipid Biosynthesis in Mycobacterium tuberculosis. AB - With the high number of patients infected by tuberculosis and the sharp increase of drug-resistant tuberculosis cases, developing new drugs to fight this disease has become increasingly urgent. In this context, analogs of the naturally occurring enolphosphates Cyclipostins and Cyclophostin (CyC analogs) offer new therapeutic opportunities. The CyC analogs display potent activity both in vitro and in infected macrophages against several pathogenic mycobacteria including Mycobacterium tuberculosis and Mycobacterium abscessus. Interestingly, these CyC inhibitors target several enzymes with active-site serine or cysteine residues that play key roles in mycobacterial lipid and cell wall metabolism. Among them, TesA, a putative thioesterase involved in the synthesis of phthiocerol dimycocerosates (PDIMs) and phenolic glycolipids (PGLs), has been identified. These two lipids (PDIM and PGL) are non-covalently bound to the outer cell wall in several human pathogenic mycobacteria and are important virulence factors. Herein, we used biochemical and structural approaches to validate TesA as an effective pharmacological target of the CyC analogs. We confirmed both thioesterase and esterase activities of TesA, and showed that the most active inhibitor CyC17 binds covalently to the catalytic Ser104 residue leading to a total loss of enzyme activity. These data were supported by the X-ray structure, obtained at a 2.6-A resolution, of a complex in which CyC17 is bound to TesA. Our study provides evidence that CyC17 inhibits the activity of TesA, thus paving the way to a new strategy for impairing the PDIM and PGL biosynthesis, potentially decreasing the virulence of associated mycobacterial species. PMID- 30292820 TI - Regulation of Mitochondrial Electron Transport Chain Assembly. AB - Mitochondrial function depends on the correct synthesis, transport, and assembly of proteins and cofactors of the electron transport chain. The initial idea that the respiratory chain protein complexes (RCCs) were independent structures in the inner mitochondrial membrane evolved after the identification of higher quaternary structures called supercomplexes (SCs), whose formation is dynamically regulated in order to accommodate cellular metabolic demands. Due to the dual genetic origin of the mitochondrial proteome, electron transport chain and SCs formation must be tightly regulated to coordinate the expression and assembly of components encoded by both genomes. This regulation occurs at different levels from gene transcription to protein, complex or SCs assembly, and might involve the participation of factors that contribute to the formation and stability of the RCCs and SCs. Here we review the cellular pathways and assembly factors that regulate RCCs and SCs formation. PMID- 30292821 TI - Biofilm-derived spores of Clostridioides (Clostridium) difficile exhibit increased thermotolerance compared to planktonic spores. AB - Biofilm-derived spores of strains of four ribotypes (001, 020, 027 & 078) of Clostridioides (Clostridium) difficile were found to exhibit increased thermotolerance compared to spores produced in planktonic culture. In addition, 'thick' and 'thin' exosporium morphotypes described previously were visualised by electron microscopy in both biofilm and planktonic spores. PMID- 30292822 TI - The non-toxigenic strain of Clostridioides difficile Z31 can prevent infection by C. difficile in experimental model piglets. AB - One of the main challenges associated with Clostridioides difficile infection (CDI) in humans and domestic animals is the lack of an effective preventive strategy. One strategy with promising results is the oral administration of non toxigenic strains of C. difficile (NTCD). Recently, Z31, a NTCD strain isolated from a healthy dog, showed promising results to prevent CDI in hamsters. Thus, the present study aimed to evaluate the capacity of Z31 to prevent CDI in piglets using an experimental model. Twenty neonatal piglets were randomly distributed in three groups: G1 - 106 spores of Z31 followed by 107 spores of a toxigenic C. difficile strain (n = 7), G2 (positive control) - 107 spores of a toxigenic C. difficile strain (n = 7), and G3 (negative control) - no biological inoculum (n = 6). All animals were kept in individual insulators and observed for 60 h. Data regarding clinical signs, macro and microscopic lesions, toxigenic culture of C. difficile, and detection of A/B toxins in the feces were evaluated. All evaluated parameters were significantly lower in animals that received Z31 compared to the positive control. Thus, oral administration of Z31 was able to prevent CDI in piglets in an experimental model. PMID- 30292823 TI - A quantitative method for evaluating cortical responses to electrical stimulation. AB - BACKGROUND: Electrical stimulation of the cortex using subdurally implanted electrodes can causally reveal structural connectivity by eliciting cortico cortical evoked potentials (CCEPs). While many studies have demonstrated the potential value of CCEPs, the methods to evaluate them were often relatively subjective, did not consider potential artifacts, and did not lend themselves to systematic scientific investigations. NEW METHOD: We developed an automated and quantitative method called SIGNI (Stimulation-Induced Gamma-based Network Identification) to evaluate cortical population-level responses to electrical stimulation that minimizes the impact of electrical artifacts. We applied SIGNI to electrocorticographic (ECoG) data from eight human subjects who were implanted with a total of 978 subdural electrodes. Across the eight subjects, we delivered 92 trains of approximately 200 discrete electrical stimuli each (amplitude 4-15 mA) to a total of 64 electrode pairs. RESULTS: We verified SIGNI's efficacy by demonstrating a relationship between the magnitude of evoked cortical activity and stimulation amplitude, as well as between the latency of evoked cortical activity and the distance from the stimulated locations. CONCLUSIONS: SIGNI reveals the timing and amplitude of cortical responses to electrical stimulation as well as the structural connectivity supporting these responses. With these properties, it enables exploration of new and important questions about the neurophysiology of cortical communication and may also be useful for pre-surgical planning. PMID- 30292824 TI - Quantitative and qualitative assessment of glymphatic flux using Evans blue albumin. AB - BACKGROUND: The glymphatic system is a proposed pathway for clearance of proteins and macromolecules from brain, and disrupted glymphatic flux is implicated in neurological disease. We capitalized on colorimetric, fluorescent, and protein binding properties of Evans blue to evaluate glymphatic flux. NEW METHOD: Twenty five MUL of 1% Evans blue-labeled albumin (EBA) in artificial cerebrospinal fluid (aCSF) was injected into the intracisternal space of anesthetized postnatal day 17 rats. Serum was collected at various time points after injection (n = 37) and EBA was measured spectrophotometrically. In separate rats (n = 3), a cranial window was placed over the parietal cortex and EBA transit was evaluated using in vivo multiphoton microscopy. Separate rats (n = 6) were processed for immunohistochemistry to examine localization of EBA. In some rats, intracranial pressure (ICP) was increased via intracisternal injection of aCSF. RESULTS: EBA was detected in serum as early as 30 min, was maximal at 4 h, and was undetectable at 72 h after intracisternal injection. Using intra-vital microscopy and immunohistochemistry EBA could be tracked from CSF to perivascular locations. Consistent with removal via glymphatic flux, increasing ICP to 40 mmHg accelerated transit of EBA from CSF to blood. COMPARISON WITH EXISTING METHODS: Transit of EBA from CSF to serum could be quantified spectrophotometrically without radioactive labeling. Glymphatic flux could also be qualitatively evaluated using EBA fluorescence. CONCLUSION: We present a novel technique for simultaneous quantitative and qualitative evaluation of glymphatic flux in rats.

AB - OBJECTIVE: Elite athletes are prone to develop oral diseases, which could increase the risk for injuries. The aim of this study was to evaluate the oral health and the composition of oral microbiota of elite rugby players compared to the general population. METHODS: We set up a case-control study by screening 24 professional rugby players (PRG) and 22 control patients (CG) for dental and gingival examinations and performed a taxonomic analysis and a predicted functional analysis of oral microbiota. RESULTS: The Decay, Missing and Filled (DMF) teeth index (5.54 +/- 6.18 versus 2.14 +/- 3.01; p = 0.01) and the frequency of gingivitis (58,33% versus 13.63%) were significantly increased in PRG compared to CG. PRG were characterized by a dysbiotic oral microbiota (Shannon Index: 3.32 +/- 0.62 in PRG versus 3.79 +/- 0.68 in CG; p = 0.03) with an increase of Streptococcus (58.43 +/- 16.84 versus 42.60 +/- 17.45; p = 0.005), the main genus implicated in caries. Predicted metagenomics of oral microbiota in rugby players was suggestive of a cariogenic metagenome favourable to the development of caries. CONCLUSIONS: Our study shows that the oral health of PRG was poorer than the general population. PRG are characterized by a dysbiotic oral microbiota with an increase of the relative abundance of Streptococcus genus, positively correlated to the weight and negatively correlated to the diversity of oral microbiota. CLINICAL SIGNIFICANCE: Dental screening should be included in the medical follow-up of professional rugby players as a part of their health management. New strategies such as using probiotics like Lactobacillus could help to control the dysbiosis of oral microbiota. PMID- 30292826 TI - Influence of corticosterone on growth, home-cage activity, wheel running, and aerobic capacity in house mice selectively bred for high voluntary wheel-running behavior. AB - Glucocorticoids, a class of metabolic hormones, impact a wide range of traits (e.g., behavior, skeletal growth, muscle maintenance, glucose metabolism), and variation in concentrations of circulating glucocorticoids (such as corticosterone), at the level of natural individual variation, in relation to endocrine disorders, or from exogenous supplementation, have manifold effects. Changes in circulating corticosterone concentrations can also impact multiple aspects of locomotor behavior, including both motivation and physical ability for exercise. To examine further the role of corticosterone in locomotor behavior and associated traits, we utilized laboratory house mice from a long-term experiment that selectively breeds for high levels of voluntary exercise. As compared with four non-selected control (C) lines, mice from the four replicate High Runner (HR) lines have ~2-fold higher baseline circulating corticosterone concentrations as well as ~3-fold higher voluntary wheel running on a daily basis, higher home cage activity when deprived of wheels, higher maximal aerobic capacity, and smaller body size; potentially, all of these differences could be modulated by circulating corticosterone. We administered 50 MUg/mL corticosterone-21 hemisuccinate in the drinking water of both HR and C male mice from weaning through ~8 weeks of age. As compared with mice from C lines, HR mice had higher endogenous corticosterone levels; higher daily wheel-running distance, duration, and speed; higher maximal oxygen consumption during forced exercise (VO2max); spent more time in the closed arms of an elevated plus maze; and had larger reproductive fat pads. For both HR and C mice, corticosterone treatment strongly suppressed endogenous circulating corticosterone levels, decreased growth rate and adult body mass, increased food and water consumption (both adjusted for body mass), increased entries into closed arms of an elevated plus maze, decreased home-cage activity (total and average intensity), decreased wheel-running distance and maximum speed, and decreased VO2max. At the suborganismal level, corticosterone treatment decreased relative adrenal, liver, and triceps surae muscle mass, as well as tail length, but increased both subdermal and reproductive fat pad masses, as well as hematocrit. Overall, the responses of both HR and C mice to corticosterone supplementation were "negative" from a health perspective. These results have significant implications for understanding both the evolution of baseline corticosterone levels and stress-related effects on activity levels. They also suggest that patients experiencing extended periods of glucocorticoid treatment might benefit from attempts to increase their physical activity as an adjuvant. PMID- 30292827 TI - Effects of ovarian hormones on emotional behaviors in dopamine D3 receptor knockout mice. AB - Ovarian hormones reportedly have beneficial effects on affective behaviors. However, the functions of ovarian hormones in neurotransmitter signaling must be identified to understand their role in anxiety and depression. Several studies have provided evidence of the relationship between ovarian hormones and the dopaminergic system, but the interaction between ovarian hormones and dopamine D3 receptor (DRD3) is poorly understood. The aim of the present study was to examine the role of DRD3 in the anxiety-like and depression-like behavioral changes induced by estrogen and progesterone. We subjected D3 receptor knockout (D3KO) and wild-type (WT) mice to a series of behavioral tests. Mice were ovariectomized 4 weeks before testing, and we randomly administered 17beta-estradiol (E2, 0.2 mg/kg), progesterone (P4, 10 mg/kg), E2 (0.2 mg/kg) plus P4 (10 mg/kg) or vehicle (VEH, corn oil, 0.2 ml) subcutaneously daily for 9 consecutive days, starting 4 days before the testing day. On the testing day, the mice were injected 30 min prior to behavioral testing. Compared with WT mice in the same treatment group, D3KO mice displayed hyperactivity in the light-dark box test (LDBT) but lower activity in the open field test (OFT). In addition, D3KO mice but not their WT littermates showed behavioral changes after E2 treatment compared with those after VEH treatment in the LDBT only. In depression tests, D3KO-VEH mice displayed significantly longer immobility times than did WT-VEH mice. In addition, only D3KO mice exhibited an obvious decrease in immobility time after E2 and P4 administration. These results indicate that the anxiolytic and antidepressant effects of ovarian hormones can be influenced by DRD3 expression and that DRD3 knockout may induce varying sensitivities to ovarian hormones that depend on various factors, including test paradigms and experiences in animal models. Our research provides a novel insight, i.e., DRD3 may play a role in the efficacy of hormone therapy. PMID- 30292828 TI - Alpha pinene modulates UVA-induced oxidative stress, DNA damage and apoptosis in human skin epidermal keratinocytes. AB - AIMS: This study aims to evaluate the protective effect of alpha pinene (AP), an essential oil monoterpene, against ultraviolet-A (UVA; 320-400 nm) induced cellular damages in human skin epidermal keratinocytes (HaCaT cells). MATERIALS AND METHODS: In this study, HaCaT cells were subjected to single UVA-irradiation (10 J/cm2) in the presence and absence of AP (30 MUM) then different cellular end points were analyzed. The protective effect of AP against UVA-induced cytotoxicity was evaluated by MTT-based metabolic assay. Generation of reactive oxygen species (ROS), alteration of mitochondrial membrane potential (MMP), DNA single- and double strand breaks (SSBs and DSBs) and apoptotic morphological changes during different treatment conditions were measured by fluorescence microscopy and spectrofluorometry. Modulatory role of AP against UVA-mediated inflammatory markers expression, nucleotide excision repair (NER) proteins and apoptotic markers expression during AP and/or UVA treatment were studied by western blot. KEY FINDINGS: Pretreatment with AP prevented UVA-induced cytotoxicity, generation of ROS, lipid peroxidation and DNA stand breaks probably through its antioxidant property. AP also inhibited UVA-induced inflammatory mediators such as NF-kappaB, TNF-alpha and IL-6 expression in HaCaT cells. Further, AP modulates NER proteins via activation of p53 and p21 thereby subsequently prevent the formation of UVA-induced cyclobutane pyrimidine dimers (CPDs). We also noticed that AP inhibits apoptotic cell death by preventing UVA induced loss of mitochondrial membrane potential through modulating Bax/Bcl-2 expression in HaCaT cells. SIGNIFICANCE: The present findings suggest that AP prevent UVA-induced oxidative stress, inflammation, DNA damages and apoptosis in human skin cells. PMID- 30292829 TI - Hepatic injury induced by thioacetamide causes aortic endothelial dysfunction by a cyclooxygenase-dependent mechanism. AB - : Liver cirrhosis is associated with a wide range of cardiovascular abnormalities including hyperdynamic circulation and cirrhotic cardiomyopathy. The pathogenic mechanisms of these cardiovascular changes are multifactorial and include vascular dysregulations. AIM: The present study tested the hypothesis that the systemic vascular hyporesponsiveness in thioacetamide (TAA)-induced liver injury model is dependent on nitric oxide (NO) and cyclooxygenase (COX) derivatives. MAIN METHODS: Wistar rats were treated with TAA for eight weeks to induce liver injury. KEY FINDINGS: The maximal contractile response in concentration-effect curves to phenylephrine was decreased in aorta from TAA-treated rats, but no differences were found in aorta without endothelium, suggesting an endothelium dependent mechanism in decreased contractile response. There was no difference in the contractile response with and without L-NAME (N(omega)-nitro-l-arginine methyl ester) in rats with liver injury, showing that the TAA treatment impairs NO synthesis. Pre-incubation of the aorta with indomethacin, a COX-inhibitor, normalized the reduced contractile response to phenylephrine in arteries from TAA group. Also, COX-2 and iNOS (inducible nitric oxide syntase) protein expression was increased in aorta from TAA group compared to control group. Animals submitted to TAA treatment had a reduction in systolic blood pressure. Our findings demonstrated that liver injury induced by TAA caused a decrease in aortic contractile response by a COX-dependent mechanism but not by NO release. Also, it was demonstrated an inflammatory process in the aorta of TAA-treated rats by increased expression of COX-2 and iNOS. SIGNIFICANCE: Therefore, there is an essential contribution of COX-2 activation in extra-hepatic vascular dysfunction and inflammation present in cirrhosis induced by TAA. PMID- 30292830 TI - Sirtuin-1 protects hair follicle stem cells from TNFalpha-mediated inflammatory stress via activating the MAPK-ERK-Mfn2 pathway. AB - OBJECTIVE: Stem cell transplantation is a promising tool to treat burn injuries. However, the inflammatory microenvironment in damaged skin limits the efficiency of stem cell-based therapy via poorly understood mechanisms. The aim of our study is to explore the contribution and mechanism of Sirtuin-1 (Sirt1) in TNFalpha mediated inflammatory stress in hair follicle stem cells (HFSCs). METHODS: Cellular viability was determined using the MTT assay, TUNEL staining, western blot analysis and LDH release assay. Adenovirus-loaded Sirt1 was transduced into HFSCs to overexpress Sirt1 in the presence of TNFalpha. Mitochondrial function was determined using JC-1 staining, mitochondrial ROS staining, immunofluorescence staining and western blotting. RESULTS: Sirt1 was downregulated in response to the TNFalpha treatment. Additionally, TNFalpha stress reduced the viability, mobility and proliferation of HFSCs, and these effects were reversed by the overexpression of Sirt1. At the molecular level, Sirt1 overexpression attenuated TNFalpha-mediated mitochondrial damage, as evidenced by increased mitochondrial energy metabolism, decreased mitochondrial ROS generation, stabilized mitochondrial potential and blockage of the mitochondrial apoptotic pathway. Furthermore, Sirt1 modulated mitochondrial homeostasis by activating the MAPK-ERK-Mfn2 axis; inhibition of this pathway abrogated the protective effects of Sirt1 on HFSC survival, migration and proliferation. SIGNIFICANCE: Based on our results, the inflammatory stress mediated HFSC injury may be associated with a decrease in Sirt1 expression and subsequent mitochondrial dysfunction. Accordingly, strategies designed to enhance Sirt1 expression would be an effective approach to enhance the survival of HFSCs in the inflammatory microenvironment. PMID- 30292831 TI - Inhibition of SRC/FAK cue: A novel pathway for the synergistic effect of rosuvastatin on the anti-cancer effect of dasatinib in hepatocellular carcinoma. AB - PURPOSE: Statins extended their hypocholestremic effect to show a promising anticancer activity. Hepatocellular carcinoma (HCC), the third common cause of cancer-related death, responded positively to statins. Some in-vitro studies reveal the rosuvastatin antitumor effect, but barely in-vivo studies. Hence, we evaluated the antitumor potential of rosuvastatin in a HCC model, the possible signaling cues involved, and whether it augments the dasatinib anticancer effect. METHOD: For the in-vitro study, the IC50 and the combination (CI)/dose reduction (DRI) indices were determined for HCC cell line (HepG2) treated with dasatinib and/or rosuvastatin. For the in-vivo study, mice with diethylnitrosamine-induced HCC were treated for 21 days with dasatinib and/or rosuvastatin (10 and 20 mg/kg, respectively). The p-focal adhesion kinase/p-rous sarcoma oncogene cellular homolog (p-FAK/p-Src) cascade and its downstream molecules were assessed. RESULTS: The in-vitro study confirmed the synergistic effect of rosuvastatin with dasatinib, which entailed the in-vivo results. The two drugs decreased the p FAK/p-Src cue along with p-Ras/c-Raf, p-STAT-3, and p-Akt levels to enhance apoptosis by an increase in caspase-3 level and a decline in survivin level. Additionally, they inhibited HGF, VEGF, and the MMP-9. Moreover, the different treatments downregulated the expression of proliferative cell nuclear antigen (PCNA) and Ki-67. The best effect was mediated by the combination regimen that surpassed the effect of either drug alone. CONCLUSION: Our results highlighted some of the signals involved in rosuvastatin antitumor effect and nominate it as an adds-on therapy with dasatinib to yield a better effect in HCC through inhibiting the FAK/Src cascade. PMID- 30292832 TI - FAK alleviates radiation-induced rectal injury by decreasing apoptosis. AB - Radiation-induced rectal injury is closely related with radiotherapy efficiency. Here, we investigated the effect of focal adhesion kinase (FAK) in radiation induced rectal injury. Peripheral blood samples of patients with rectal cancer were collected prior to radiotherapy. Differentially expressed genes and copy number variations (CNVs) were analyzed by microarray analysis. The CTCAE v3.0 toxicity grades were used to assess acute rectal injury. The radiosensitivity of human intestinal epithelial crypt (HIEC) cells were assayed by colony formation, mitochondrial membrane potential, flow cytometry and western blotting. The rectums of C57BL/6 mice were X-irradiated locally with a single dose of 15 Gy. The effect of FAK on radiation-induced injury was investigated by hematoxylin eosin (H&E) staining, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL), immunohistochemistry (IHC) and quantitative real-time PCR (qRT-PCR). FAK mRNA level was inversely correlated with rectal injury severity in patient samples. A CNV amplification located on chromosome 8 was closely related with FAK. Further functional assays revealed increased levels of gammaH2AX expression and apoptosis-related proteins in FAK-silenced HIEC cells. The ratio of TUNEL, cl-caspase-3, cyto-c and bax/bcl-2 expression in the rectum mucosa treated with a FAK inhibitor increased significantly. These results demonstrated that FAK reduced radiation-induced rectal injury by decreasing apoptosis. PMID- 30292833 TI - Nicotinamide mononucleotide alleviates Aluminum induced bone loss by inhibiting the TXNIP-NLRP3 inflammasome. AB - Aluminum (Al) recognized as a persistent environmental contaminant is associated with bone diseases. Nicotinamide mononucleotide (NMN) is an intermediate of nicotinamide adenine dinucleotide (NAD+) biosynthesis widely used to replenish NAD+. Increasing evidences demonstrated that replenishment of NAD+ can protect against bone loss. However, the potentially protective effects of NMN against Al induced bone impairment and the underlying mechanisms remain unknown. In the present study, we sought to investigate the protective effects of NMN on Al induced bone damages and elucidate the potential mechanisms. We orally exposed AlCl3 (10 mg/L) to Sprague-Dawley rats in drinking water for 12 weeks while NMN (20 mg/kg) were intraperitoneally injected in last 4 weeks. We found that Al could induce bone damages, bone loss and oxidative stress. In addition, we showed that Al triggered inflammatory responses, which is mediated by the NOD-like receptor pyrin domain containing 3 (NLRP3) inflammasome activation. However, NMN treatment significantly alleviated Al-induced bone injuries by decreasing bone loss, suppressing oxidative stress as well as inhibiting Thioredoxin-interacting protein (TXNIP)-NLRP3 inflammasome pathway and pro-inflammatory cytokine production in vivo and in vitro. Meanwhile, treatment with TXNIP siRNA performed the same protective effects as NMN in Al-treated MC3T3-E1 cells. Collectively, our results suggest that NMN may reduce Al-induced bone loss partly by suppression of the TXNIP-NLRP3 inflammasome pathway. PMID- 30292834 TI - Solubility changes of promyelocytic leukemia (PML) and SUMO monomers and dynamics of PML nuclear body proteins in arsenite-treated cells. AB - Promyelocytic leukemia (PML) and a suite of other proteins form nuclear bodies (NBs) where SUMOylation of PML and tumor suppression events occur in response to arsenite (As3+) treatment. Soluble PML is rapidly modified to the insoluble form in response to As3+, yet the relationship between the solubility change and nuclear localization of PML and PML-nuclear body (PML-NB) proteins remained elusive. We have investigated differences in the solubility change of well-known PML-NB proteins such as death-associated protein 6 (DAXX), SUMO, and PML in genetically engineered HEK293, and Jurkat and HL60 cells. The solubility of PML and SUMO2/3 monomers in RIPA solution decreased in 2 h in response to As3+. Live image analysis of GFP-PML revealed that extranuclear PML was insoluble in RIPA irrespective of the As3+-treatment and PML in PML-NBs, which was soluble in the untreated cells, was converted to insoluble forms by As3+. The solubility of DAXX was not changed by As3+, even though PML and DAXX co-localized completely in the subcellular compartments. Murine double mutant 2 (MDM2), which is known to interacts with intranuclear PML, did not affect the As3+-induced solubility change of PML. These results indicate that As3+ selectively reorganizes PML and SUMO2/3 monomers into insoluble forms in PML-NBs, and then PML SUMOylation proceeds.

PMID- 30292836 TI - Body appreciation in British men: Correlates and variation across sexual orientation. AB - Investigations of positive body image among men and across various social identities are lacking, and could contribute to a more complete understanding of the construct, including how positive body image can be improved. This study addressed this gap by investigating correlates of body appreciation - a key facet of positive body image - in men, and testing whether levels of body appreciation vary across sexual orientation. Data from a British community sample of 439 men (Mage = 39.13) showed that body appreciation inversely correlated with conformity to masculine norms and upward appearance-based social comparisons, and positively correlated with physical activity. Body appreciation was lower among sexual minority compared to heterosexual men, and athletic appearance-ideal internalisation and upward appearance-based social comparisons mediated this relationship. Replicating prior research among men, body appreciation positively correlated with body satisfaction, and inversely correlated with perceived appearance pressures from media and eating pathology. These findings have implications for interventions addressing body image among men. PMID- 30292837 TI - Quantitative MRI analysis of infrapatellar and suprapatellar fat pads in normal controls, moderate and end-stage osteoarthritis. AB - The aim of this study was to analyze the magnetic resonance imaging (MRI) volumetric and morphometric characteristics of the infrapatellar fat pad (IFP) and the suprapatellar fat pad (SFP) in normal controls, moderate and end-stage osteoarthritis (OA) patients. Forty-four MRI images of the three groups were collected: a) 17 patients undergoing meniscectomy with Outerbridge score 0 (control group); b) 15 patients undergoing meniscectomy with Outerbridge score 3/4 (moderate OA group); and c) 12 patients undergoing total knee replacement (end-stage OA group). Volume, depth, femoral and tibial arch lengths of IFP were quantified. The hypointense IFP signals were also scored. The SFP volume, oblique, antero-posterior and cranio-caudal lengths were determined. IFP and SFP characteristics were compared between groups. A decrease of IFP volume, depth, femoral, and tibial arch lengths in moderate and end-stage OA compared to controls were observed. A difference in IFP hypointense signal was found between groups. No differences were found in SFP characteristics between the groups. In controls and moderate OA patients, correlations were found among the different MRI characteristics of both IFP and SFP, while in the end-stage OA group correlations were found only in SFP. We evidenced differences of the IFP MRI morphometric characteristics between the groups analyzed, supporting an important role of IFP in OA pathology and progression. On the contrary, no differences were highlighted in SFP analysis suggesting that this fat pad is not clearly involved in OA, probably due to its peculiar localization and different function. PMID- 30292838 TI - New triterpenoid saponins from the leaves of Ilex chinensis. AB - Eight new triterpenoid saponins, including four ursane-type saponins, ilexchinenosides J-M (1-4), and four oleanane-type saponins, ilexchinenosides N-Q (5-8), along with three known triterpenoid saponins (9-11) were isolated from the leaves of Ilex chinensis Sims. Their structures were established by 1D, 2D NMR and MS spectroscopic analyses and through comparisons with known compounds. Moreover, compounds 1, 3, 5, 7-9 and 11 exhibited significant levels of hepatoprotective activity against N-acetyl-p-aminophenol (APAP)-induced HepG2 cell damage in in vitro assays while compound 10 had moderately inhibitory effects on the NO production of lipopolysaccharide (LPS)-induced murine macrophages. PMID- 30292839 TI - Bisphenol S (BPS) triggers the migration of human non-small cell lung cancer cells via upregulation of TGF-beta. AB - As one of the leading causes of cancer deaths world-wide, the progression of human non-small cell lung cancer (NSCLC) can be regulated by estrogenic signals. Our present data showed that an industrial endocrine disrupting chemical, bisphenol S (BPS), can promote the in vitro migration of NSCLC cells, which was evidenced by the upregulation of vimentin and matrix metalloproteinase-2 (MMP-2). BPS can increase the mRNA and protein expression of IL-10 and TGF-beta. While only targeted inhibition of TGF-beta can block BPS induced migration of NSCLC cells. The upregulation of TGF-beta can further activate the Smad-2/3 pathways. Further, BPS induced expression of TGF-beta was ERalpha/beta or G protein-coupled estrogen receptor (GPER) independent, since targeted inhibition of ERalpha/beta or GPER had no effect on BPS induced transcription of TGF-beta. We identified that the inhibitor of ERK1/2 can attenuate BPS induced expression of TGF-beta and activation of Smad-2/3 pathways. Collectively, we found that nanomolar BPS can trigger the in vitro migration of NSCLC cells via ERK1/2 mediated activation of TGF-beta/Smad-2/3 pathways. PMID- 30292840 TI - Widespread distribution of tauopathy in preclinical Alzheimer's disease. AB - The objective of this study was to examine the distribution and severity of tau PET binding in cognitively normal adults with preclinical Alzheimer's disease as determined by positive beta-amyloid PET. 18F-AV-1451 tau-PET data from 109 cognitively normal older adults were processed with 34 cortical and 9 subcortical FreeSurfer regions and averaged across both hemispheres. Individuals were classified as being beta-amyloid positive (N = 25, A+) or negative (N = 84, A-) based on a 18F-AV-45 beta-amyloid-PET standardized uptake value ratio of 1.22. We compared the tau-PET binding in the 2 groups using covariate-adjusted linear regressions. The A+ cohort had higher tau-PET binding within 8 regions: precuneus, amygdala, banks of the superior temporal sulcus, entorhinal cortex, fusiform gyrus, inferior parietal cortex, inferior temporal cortex, and middle temporal cortex. These findings, consistent with preclinical involvement of the medial temporal lobe and parietal lobe and association regions by tauopathy, emphasize that therapies targeting tauopathy in Alzheimer's disease could be considered before the onset of symptoms to prevent or ameliorate cognitive decline. PMID- 30292841 TI - Exploring Shared Mental Models of surgical teams in Video-Assisted Thoracoscopic Surgery lobectomy. AB - BACKGROUND: Non-technical skills are important for safe and efficient surgery. Teams performing Video-Assisted Thoracoscopic Surgery (VATS) lobectomy express that it is of utmost importance to have a Shared Mental Model (SMM) of the patient, current situation, and team resources. However, these SMMs have never been explored in a clinical setting. The aim of this observational study was to measure the similarity of SMMs within teams performing VATS lobectomy. METHODS: In this national, multi-center study, SMMs of teams performing VATS lobectomy (n=64) were measured by pre- and postoperative questionnaires that were completed by all team members (n=172). Participants' responses were compared within each team to explore SMMs of risk assessment, familiarity, technical skills, non technical skills, and problems. RESULTS: Analysis showed poor agreement between team members with respect to risk assessment, but higher levels of agreement were found for assessments of familiarity, technical and non-technical skills within the team (Cronbach's alpha=0.90), most notably for surgical subteams (=surgeon+assistant surgeon+surgical nurses). During the surgical procedure, the most frequent problems were related to anesthesia, and these were most often recognized by the surgeons. The operating room nurses were the least aware of each other's and the surgeons' problems. CONCLUSIONS: Significant variation exists in the SMMs among VATS team members, with poor agreement regarding the patient and current situation, but better agreement with respect to team resources. Focus on pre-operative and peri-operative team reflexivity, in addition to explicit communication within unfamiliar teams, may provide opportunities to enhance SMMs, with possible downstream effects on team performance. PMID- 30292842 TI - Predictors of Failure of Medical Management in Uncomplicated Type B Aortic Dissection. AB - BACKGROUND: Optimal medical therapy (OMT) for uncomplicated type B aortic dissection (uTBAD) provides excellent short-term outcomes but is associated with a high incidence of failure. This study identified predictors of aortic intervention and mortality in uTBAD patients undergoing OMT. METHODS: A retrospective review of the Emory aortic database from 2000-2016 identified 314 uTBAD patients undergoing OMT. Two hundred and sixty-three (84%) patients had imaging at presentation analyzed for maximum aortic diameters (AD), false lumen (FL) status, and visceral vessel perfusion. Cox proportional hazards models were constructed to estimate hazards ratios (HR) and identify predictors of OMT failure. RESULTS: The mean age of patients was 58+/-12 years, and 67% were male. FL status was patent in 59.4%, partially thrombosed in 39.8%, and completely thrombosed in 0.8% of patients. Over a median follow-up of 5.6 [IQR: 1.4-8.5] years, 44.9% of patients failed OMT and underwent intervention: n=58 open, n=83 endovascular. The estimated incidence of OMT failure was 46%. Multivariate analysis identified the presence of diabetes, renal failure, DeBakey 3B dissection and a descending thoracic AD of >=4.5cm [HR: 1.39 (1.24, 1.56), p<0.001] to be independent predictors of failure of OMT. FL status or the distribution of visceral vessels arising from the FL did not predict OMT failure. CONCLUSIONS: There is a significant incidence of OMT failure in uTBAD patients. A descending thoracic AD of >=4.5cm at the time of diagnosis is an independent predictor of failure of OMT. PMID- 30292843 TI - Toll-Like Receptor-4 Is a Mediator of Proliferation in Esophageal Adenocarcinoma. AB - BACKGROUND: Chronic inflammation from reflux disease has been implicated as part of the development of esophageal adenocarcinoma. Toll-like receptors (TLRs), a component of the innate immune system, have been implicated in mediating hyperplasia and metaplasia in response to inflammatory stimuli. Increased TLR4 in human esophageal cancer has been correlated with its carcinogenesis. We hypothesized that TLR4 mediates proliferation of human esophageal adenocarcinoma cells. METHODS: Normal human esophageal (HET1A) and adenocarcinoma (OE33, FLO-1) cell lines were cultured using standard techniques. TLR4 was measured at baseline and in response to reflux stimuli. All cell lines were treated with the TLR4 agonist lipopolysaccharide for 48 hours, and growth response was measured. Changes in myeloid differentiation primary response 88 (MyD88), tumor necrosis factor receptor associated factor 6 (TRAF6), and nuclear factor-kappaB (NF kappaB) activity were measured during lipopolysaccharide treatment. All cell lines had NF-kappaB inhibited, and growth rate response was measured. RESULTS: TLR4 was expressed in all cell lines, with increased baseline expression in adenocarcinoma cell lines (p < 0.05). Reflux stimuli increased TLR4 expression (p < 0.01) in normal esophageal cells. After treatment with lipopolysaccharide, all cell lines showed significant increases in proliferation (p < 0.05) due to the NF kappaB pathway, and their growth rate was reduced with NF-kappaB inhibition (p < 0.05). CONCLUSIONS: TLR4 is consistently detectable in esophageal cell lines and most highly expressed in adenocarcinoma. TLR4 expression increases in an inflammatory model of reflux disease. TLR4 activation results in increased proliferation due to the TLR4-MyD88-TRAF6-NF-kappaB signaling pathway, and inhibition of NF-kappaB leads to decreased esophageal cell growth. These findings suggest TLR4 may be a target to suppress esophageal cancer growth. PMID- 30292844 TI - Feasibility and Outcomes of TAVI using the Left Axillary Artery as Primary Access Site. AB - BACKGROUND: The femoral artery is generally used as primary access for TAVI. However, peripheral artery disease often precludes femoral access. The purpose of this study was to describe clinical outcome of TAVI using the left axillary artery (LAA) as primary access site. METHODS: From December 2008 until June 2016, data on all consecutive patients treated with a Medtronic device via the LAA at our hospital were registered and outcome was prospectively collected according to the updated VARC-2 criteria. Mortality check was performed nationally. RESULTS: In total 362 patients were included (median age 80[76-84] years, logistic Euroscore 17+/-12%). Successful axillary access was achieved in 99%. Medtronic CoreValve(86%) and Evolut R(14%) (Medtronic, Minneapolis, Minnesota, USA) were implanted. Major vascular complications occurred in 5% of patients, 1% was LAA related. Life-threatening and major bleeding was observed in 2% and 10%, respectively. Additional complications were: new LBBB (30%), new permanent pacemaker (11%) and stroke (1%). There were 6(2%) procedural deaths and 19(5%) deaths within 30 days. One-year mortality rate was 19%. CONCLUSIONS: This is the first study reporting on outcome after TAVI using the LAA as default access. We conclude that it is highly feasible and safe with low rates of major vascular complications, bleeding and stroke. PMID- 30292845 TI - Valve Sparing Root Replacement Provides Excellent Mid-Term Outcomes for Bicuspid Valve Aortopathy. AB - BACKGROUND: Standard therapy for aortic root dilation in the setting of bicuspid aortic valves remains use of a composite valve conduit. The long-term durability of valve sparing root replacement (VSRR) in bicuspid aortopathy is presently unclear. In this study, the mid-term results of performing VSRR in the setting of a bicuspid valve was analyzed. METHODS: A single institutional database identified 280 patients who underwent VSRR from 2005-2016. Outcomes were analyzed in 60 consecutive patients undergoing a VSRR in the setting of a bicuspid aortic valve with aortic insufficiency (AI). Patients were followed prospectively and had annual echocardiograms. RESULTS: The average age in this series was 42+/-11 years. Eighty percent were male and 33% had NYHA Class III-IV symptoms. More than 2+ AI was present in 42% of patients preoperatively. The incidence of operative death, stroke, and renal failure was 0%. Mean follow-up was 39+/-30 months. At latest follow-up, 62% of patients had zero AI and 87% of patients had <1+ AI. At 5 years, freedom from >2+ AI was 97% and freedom from AVR was 96%. Preoperative AI was not found to be a significant risk factor for postoperative >2+ AI (p=0.61) or AVR (p=0.61). CONCLUSIONS: VSRR can be safely and effectively performed in young patients with bicuspid valve anatomy regardless of degree of pre-operative AI. Valve function is durable and the incidence of valve-related complications is low. VSRR is an attractive and potentially superior option to conventional root replacement in appropriately selected patients with bicuspid aortopathy.

AB - Hypothermic circulatory arrest and selective cerebral perfusion are standard procedures during total arch replacement to treat acute type A aortic dissection. However, organ ischemia during anastomosis between the graft and descending aorta contribute to high risk of mortality and morbidity. Here we describe the combination of antegrade cerebral perfusion and retrograde inferior vena caval perfusion as a way to ensure continual perfusion of the brain, abdominal viscera and spinal cord during anastomosis and thereby improve outcomes of total arch replacement. PMID- 30292847 TI - Comparing Two Imaging Methods for Follow-up of Lung Cancer Treatment: A Randomized Pilot Study. AB - BACKGROUND: Scientific data on the image modality to be used in post-curative treatment surveillance of non-small-cell lung cancer patients are scarce. This prospective randomized pilot trial aimed to compare the performance of integrated 18F-fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) and contrast-enhanced computed tomography (CE-CT).. METHODS: After termination of curative-intent treatment, patients were randomly assigned to either the PET-CT or the CE-CT group. Imaging procedures were performed every 6 months for 2 years. If suspicious radiologic findings were detected or patients became symptomatic, a diagnostic work-up was initiated. Sensitivity, specificity, and positive predictive value for detecting cancer recurrence were calculated for both imaging procedures. RESULTS: There were 96 patients enrolled in the study. In 14 of 50 patients (28%) in the PET-CT group and in 14 of 46 patients (30%) in the CE-CT group, a suspicious radiologic finding was confirmed as cancer recurrence after diagnostic work-up. False positive findings were detected in 11 patients (22%) of the PET-CT and 8 patients (17%) of the CE-CT group. The sensitivity, specificity, and positive predictive value for detecting cancer recurrence were 0.88 (95% CI: 0.62-0.98), 0.62 (0.42-0.79), and 0.56 (0.35-0.76) for PET-CT and 0.93 (0.68 1.00), 0.72 (0.53-0.87), and 0.64 (0.41-0.83) for CE-CT, respectively. CONCLUSIONS: The results of our study suggest that PET-CT is not superior to CE CT in detecting cancer recurrence during 2 years following curative-intent treatment of non-small-cell lung cancer. PMID- 30292848 TI - SAMHD1 and the innate immune response to cytosolic DNA during DNA replication. AB - Cytosolic DNA of endogenous or exogenous origin is sensed by the cGAS-STING pathway to activate innate immune responses. Besides microbial DNA, this pathway detects self-DNA in the cytoplasm of damaged or abnormal cells and plays a central role in antitumor immunity. The mechanism by which cytosolic DNA accumulates under genotoxic stress conditions is currently unclear, but recent studies on factors mutated in the Aicardi-Goutieres syndrome cells, such as SAMHD1, RNase H2 and TREX1, are shedding new light on this key process. In particular, these studies indicate that the rupture of micronuclei and the release of ssDNA fragments during the processing of stalled replication forks and chromosome breaks represent potent inducers of the cGAS-STING pathway.

AB - INTRODUCTION: Our study aimed to analyze the prognostic implication of the multiplicity of solid portions in part-solid nodules (PSNs) on computed tomography scans and compare the prognostic performance of various measures of solid portions, including the single largest solid portion, solid proportion, and summated multiple solid portion measurements. METHODS: The cases of a total of 345 patients with surgically resected stage IA adenocarcinomas manifesting as PSNs were retrospectively reviewed. The multiplicity of the solid portion in PSNs was determined and the diameter of each solid portion was measured. The prognostic implication of the multiplicity of the solid portion and other clinical variables in relation to disease-free survival (DFS) was analyzed by using Cox regression. In addition, risk stratification based on the single largest solid portion, sum of the solid portions, single solid proportion, and sum of the solid proportions was conducted. Next, concordance indices (C-indices) for DFS were obtained for each measure and compared. Intrareader and interreader measurement variability was assessed. RESULTS: Multiplicity of the solid portion did not have a significant effect on DFS; clinical T category was the only independent risk factor for tumor recurrence (p < 0.05). The C-index of the single solid portion (conventional clinical T category) was 0.817 (95% confidence interval: 0.691-0.942). There were no significant differences (p > 0.05) between the C-indices of the single solid portion and other solid portion measures. Interreader measurement variability was substantial. CONCLUSIONS: The current clinical T categorization of PSNs based on the single solid portion measurement is appropriate. PMID- 30292850 TI - Prophylactic Cranial Irradiation for Limited-Stage Small-Cell Lung Cancer Patients: Secondary Findings From the Prospective Randomized Phase 3 CONVERT Trial. AB - INTRODUCTION: The impact of the dose and fractionation of thoracic radiotherapy on the risk of developing brain metastasis (BM) has not been evaluated prospectively in limited stage SCLC patients receiving prophylactic cerebral irradiation (PCI). METHODS: Data from patients treated with PCI from the CONVERT trial were analyzed. RESULTS: Four hundred forty-nine of 547 patients (82%) received PCI after completion of chemoradiotherapy. Baseline brain imaging consisted of computed tomographic scans in 356 of 449 patients (79%) and magnetic resonance imaging in 83 of 449 (18%) patients. PCI was delivered to 220 of 273 participants (81%) in the twice-daily (BD) group and 229 of 270 in the once-daily (OD) group (85%; p = 0.49). Total median PCI dose was 25 Gy in both the BD and OD groups (p = 0.74). In patients who received PCI, 75 (17%) developed BM (35 [8%] in OD and 40 [9%] in BD) and 173 (39%) other extracranial progression. In the univariate analysis, gross tumor volume (GTV) was associated with an increased risk of BM (p = 0.007) or other radiological progression events (p = 0.006), whereas in a multivariate analysis both thoracic GTV (tGTV) and ECOG performance score (PS) were associated with either progression type. The median overall survival (OS) of patients treated with PCI was 29 months. In the univariate analysis of OS, PCI timing from end of chemotherapy, weight loss of more than 10%, and tGTV were prognostic factors associated with OS. In the multivariate analysis, only tGTV was associated with OS. Delay between end of chemotherapy and PCI was not associated with OS. CONCLUSIONS: Patients receiving OD or BD thoracic radiotherapy have the same risk of developing BM. Larger tumors are associated with a higher risk of BM. PMID- 30292851 TI - Minimally Invasive Approaches Do Not Compromise Outcomes for Pneumonectomy: A Comparison Using the National Cancer Database. AB - INTRODUCTION: Minimally invasive approaches are increasingly being used for the conduct of complex surgical procedures. Whether the benefits of minimally invasive approaches compared to thoracotomy for sublobar and lobar lung resection for NSCLC are realized for patients undergoing pneumonectomy is not clear. METHODS: The National Cancer Database was queried for patients who underwent pneumonectomy for NSCLC from 2010 to 2014. Case data from patients who underwent resection by minimally invasive surgery (MIS) were compared with those from patients who received thoracotomy (open) in an intention-to-treat analysis. Associations between potential covariates and treatment were analyzed using the Pearson chi-square test for categorical variables and Wilcoxon rank sum test for continuous variables. Univariable and multivariable logistic models and proportional hazards model were used to assess the effect of surgical approach on 30-day and 90-day mortality and overall survival. Relative prognosis was summarized using odds ratios and hazards ratios estimates and 95% confidence limits. RESULTS: A total of 4,938 patients underwent pneumonectomy during the study period, of which 755 (15.3%) were completed by MIS. No difference was noted in 30- and 90-day mortality rates for MIS compared to open approaches (6.8% and 12.3% versus 6.7% and 11.9%, respectively; p = 0.9 and 0.86, respectively). Tumor histology and stage characteristics were similar between the two groups. The mean number of lymph nodes examined was higher in the MIS group compared to the open thoracotomy group (17.1 +/- 0.4 versus 16.1 +/- 0.2, p = 0.034). The conversion rate for the MIS cohort was 36.7%. Surgical approach was not associated with any difference in perioperative mortality with univariable or multivariable analysis. MIS was associated with improved overall survival on univariable analysis, but this was not evident with multivariable analysis. CONCLUSIONS: Pneumonectomy performed by minimally invasive approaches does not compromise perioperative mortality or long-term outcomes. Further investigation into the impact of minimally invasive approaches on perioperative outcomes for whole-lung resection is warranted. PMID- 30292852 TI - Toxicity Related to Radiotherapy Dose and Targeting Strategy: A Pooled Analysis of Cooperative Group Trials of Combined Modality Therapy for Locally Advanced Non Small Cell Lung Cancer. AB - OBJECTIVE: Concurrent chemoradiotherapy (CRT) was the standard treatment for locally advanced NSCLC (LA-NSCLC). This study was performed to examine thoracic radiotherapy (TRT) parameters and their impact on adverse events (AEs). METHODS: We collected individual patient data from 3600 patients with LA-NSCLC who participated in 16 cooperative group trials of concurrent CRT. The TRT parameters examined included field design strategy (elective nodal irradiation [ENI] versus involved-field [IF] TRT [IF-TRT]) and TRT dose (60 Gy versus >=60 Gy). The primary end point of this analysis was the occurrence of AEs. ORs for AEs were calculated with univariable and multivariable logistic models. RESULTS: TRT doses ranged from 60 to 74 Gy. ENI was not associated with more grade 3 or higher AEs than IF-TRT was (multivariable OR = 0.77, 95% confidence interval [CI]: 0.543 1.102, p = 0.1545). Doses higher than 60 Gy (high-dose TRT) were associated with significantly more grade 3 or higher AEs (multivariable OR = 1.82, 95% CI: 1.501 2.203, p < 0.0001). In contrast, ENI was associated with significantly more grade 4 or higher AEs (multivariable OR = 1.33, 95% CI: 1.035-1.709, p = 0.0258). Doses higher than 60 Gy were also associated with more grade 4 or higher AEs (multivariate OR = 1.42, 95% CI: 1.191-1.700, p = 0.0001). Grade 5 AEs plus treatment-related deaths were more frequent with higher-dose TRT (p = 0.0012) but not ENI (p = 0.099). CONCLUSIONS: For patients with LA-NSCLC treated with concurrent CRT, IF-TRT was not associated with the overall risk of grade 3 or higher AEs but was associated with significantly fewer grade 4 or higher AEs than ENI TRT. This is likely the result of irradiation of a lesser amount of adjacent critical normal tissue. Higher TRT doses were associated significantly with grade 3 or higher and grade 4 or higher AEs. On the basis of these findings and our prior report on survival, CRT using IF-TRT and 60 Gy (conventionally fractionated) were associated with more favorable patient survival and less toxicity than was the use of ENI or higher radiotherapy doses. PMID- 30292853 TI - Atlas of Axial Spondyloarthritis in Spain 2017: Study Design and Population. AB - OBJECTIVE: Atlas of Axial Spondyloarthritis in Spain 2017 aims to better understand the reality of the patients suffering from this disease from an integrated approach. METHODS: The Atlas 2017 based its results on an extensive cross-sectional patient survey conducted in Spain (2016), validated by a multidisciplinary group of experts on spondyloarthritis. RESULTS: Data from 680 patients with axSpA were obtained, most of them suffered from AS, were HLA-B27 positive, older than 45 years, and live as part of a couple. A large percentage had university studies, were disabled and members of a patient association. Patients reported a diagnostic delay of 8.5 years, high disease activity (BASDAI 5.5+/-2.2), moderate-important stiffness (61.0%), medium-high functional limitation (74.9%), and psychological distress (GHQ 5.7+/-4.5). A total of 54.7% reported taking NSAIDs, 28.4% DMARDs, 36.3% biological therapy and 32.2% were not receiving pharmacological treatment. CONCLUSIONS: The Atlas survey data reveals still a long diagnostic delay, high disease activity, psychological distress, while an important proportion could be undertreated. PMID- 30292854 TI - Utilizing soft constraints to enhance medical relation extraction from the history of present illness in electronic medical records. AB - Relation extraction between medical concepts from electronic medical records has pervasive applications as well as significance. However, previous researches utilizing machine learning algorithms judge the semantic types of medical concept pair mentions independently. In fact, different concept pair mentions in the same context are of dependencies which can provide beneficial evidences for identifying their relation types. To the best of our knowledge, only one study has considered such dependencies in discharge summaries. However, its hard constraints are not applied effectively to the History of Present Illness (HPI) in electronic Medical Records. According to the writing characteristics of HPI records, we generalize two regularities of dependencies among concept pairs mentioned in an HPI record to enhance the performance of relation extraction. We incorporate the two soft constraints corresponding to the regularities and the posterior probabilities returned by a local classifier into a joint inference process which applies Integer Quadratic Programming method to carry out collective classification for all concept pair mentions in an HPI record. We implement four local classification models including support vector machine, logistics regression, random forest and piecewise convolutional neural networks to examine the performance of our approach. A series of experimental results demonstrate that our collective classification method has made a principal improvement and outperforms the other state-of-the-art methods. PMID- 30292855 TI - Social media mining for birth defects research: A rule-based, bootstrapping approach to collecting data for rare health-related events on Twitter. AB - BACKGROUND: Although birth defects are the leading cause of infant mortality in the United States, methods for observing human pregnancies with birth defect outcomes are limited. OBJECTIVE: The primary objectives of this study were (i) to assess whether rare health-related events-in this case, birth defects-are reported on social media, (ii) to design and deploy a natural language processing (NLP) approach for collecting such sparse data from social media, and (iii) to utilize the collected data to discover a cohort of women whose pregnancies with birth defect outcomes could be observed on social media for epidemiological analysis. METHODS: To assess whether birth defects are mentioned on social media, we mined 432 million tweets posted by 112,647 users who were automatically identified via their public announcements of pregnancy on Twitter. To retrieve tweets that mention birth defects, we developed a rule-based, bootstrapping approach, which relies on a lexicon, lexical variants generated from the lexicon entries, regular expressions, post-processing, and manual analysis guided by distributional properties. To identify users whose pregnancies with birth defect outcomes could be observed for epidemiological analysis, inclusion criteria were (i) tweets indicating that the user's child has a birth defect, and (ii) accessibility to the user's tweets during pregnancy. We conducted a semi automatic evaluation to estimate the recall of the tweet-collection approach, and performed a preliminary assessment of the prevalence of selected birth defects among the pregnancy cohort derived from Twitter. RESULTS: We manually annotated 16,822 retrieved tweets, distinguishing tweets indicating that the user's child has a birth defect (true positives) from tweets that merely mention birth defects (false positives). Inter-annotator agreement was substantial: kappa = 0.79 (Cohen's kappa). Analyzing the timelines of the 646 users whose tweets were true positives resulted in the discovery of 195 users that met the inclusion criteria. Congenital heart defects are the most common type of birth defect reported on Twitter, consistent with findings in the general population. Based on an evaluation of 4169 tweets retrieved using alternative text mining methods, the recall of the tweet-collection approach was 0.95. CONCLUSIONS: Our contributions include (i) evidence that rare health-related events are indeed reported on Twitter, (ii) a generalizable, systematic NLP approach for collecting sparse tweets, (iii) a semi-automatic method to identify undetected tweets (false negatives), and (iv) a collection of publicly available tweets by pregnant users with birth defect outcomes, which could be used for future epidemiological analysis. In future work, the annotated tweets could be used to train machine learning algorithms to automatically identify users reporting birth defect outcomes, enabling the large-scale use of social media mining as a complementary method for such epidemiological research. PMID- 30292857 TI - Testosterone, androstenedione and dehydroepiandrosterone concentrations in pregnant Spanish Purebred mare. AB - Androgens modulate maternal ovarian activity, embryo implantation and correct placental development. The objective of this study was to establish reference values for testosterone (T), androstenedione (A4) and dehydroepiandrosterone (DHEA) concentrations in pregnant mares. A total of 30 healthy Spanish Purebred mares with an age range of 9.33 +/- 3.31 years, were studied during the 11 months of gestation. T, A4 and DHEA concentrations were determined using EIA validated specifically for equines. T increased in the 2nd and 3rd month (P < 0.05), showing a plateau between the 4th and 6th month, decreased from the 7th to the 9th month (P < 0.05) and increased in the 10th month (P < 0.05), reaching the maximum value in the last month of pregnancy (P < 0.05). A4 increased in the 2nd month (P < 0.05), reaching the maximum value in the 3rd month (P < 0.05), decreased in the 4th month, increasing in the 5th and 6th month (P < 0.05). From the 7th month the average values decreased until reaching the minimum at the end of gestation. DHEA progressively increased from the 1st to the 5th month, at which time the maximum mean value was reached (P < 0.05), after a decrease in the 6th and 7th month occurred (P < 0.05), reaching the minimum value in the last month of gestation. T, A4 and DHEA were positive and significantly correlated (P < 0.05). The androgens analyzed in this study can be used as predictive markers of pregnancy in the mare. PMID- 30292856 TI - Differences in the thermal sensitivity and seminal quality of distinct ovine genotypes raised in tropical conditions. AB - For different ovine breeds to maximize their reproductive capacity in countries with tropical climate, it is important to evaluate their potential for thermal resilience and consequences on their reproductive traits. Therefore, the objective of this study was to evaluate the effect of thermal environment temperatures of climate seasons in a tropical climate region on the surface temperatures of the scrotum, testicular biometric characteristics, seminal quality and serum testosterone concentration of rams of different genotypes. Breeders of four different genotypes (Dorper, n = 8, Texel, n = 8, Santa Ines, n = 9 and Morada Nova, n = 8) were used throughout the four climate seasons. Higher thermal challenge was recorded in the spring and summer. In the summer increase in scrotal surface temperature was detected by infrared thermography (P < 0.05), mainly in the regions of the distal testicular pole and tail of the epididymis. The animals of the Texel genotype had higher rectal temperature in the summer. In spring, this genotype also had the highest testicular pole (32.2 +/- 0.5 degrees C; P < 0.05) and distal (29.9 +/- 0.4 degrees C; P < 0.05) temperatures and a higher mean testicular temperature (31.7 +/- 0.4 degrees C; P < 0.05). The Morada Nova genotype showed a higher surface temperature gradient between testicular poles (2.96 +/- 0.1 degrees C; P < 0.05), especially in spring. Genotype-dependent thermal sensitivity was detected for the thermal gradient between the testicular poles, reflecting the seminal quality. There was a positive correlation of the thermal gradient between testicular poles with sperm membrane integrity and negative correlation with total sperm defects. The Texel genotype showed less progressive motility and higher percentage of sperm defects. There was no difference in testosterone concentration between genotypes and in the different seasons (P > 0.05). Thus, the indigenous genotypes showed a greater capability to maintain the scrotum-testicular thermoregulation. Dorper animals resembled the indigenous sheep genotypes, in terms of seminal characteristics, unlike Texel animals, which showed lower adaptability and lower seminal quality. PMID- 30292858 TI - Monthly changes in testicular blood flow dynamics and their association with testicular volume, plasma steroid hormones profile and semen characteristics in rams. AB - The present detailed study aimed to establish for the first time reference values for ultrasound measures of testicular dimensions and Doppler measures of blood flow in the testicular artery of rams over a 12-month period, and to investigate a possible association between monthly changes in dynamics of testicular blood flow from one hand and testicular volume, plasma testosterone and estradiol 17beta concentrations as well as semen characteristics from the other hand. Five fat-tailed rams weighing 45-60 kg and aging 2-4 years old were subjected to semen collection, jugular blood sampling, ultrasonographic scanning of the testes and Doppler examination of testicular artery twice monthly for a period of one year. The overall mean (+/-SD) values for testicular volume as well as RI (resistive index) and PI (pulsatility index), respectively were 71.84 +/- 5.33 mm3, 0.378 +/ 0.102 and 0.642 +/- 0.208. Average testicular volume was the lowest in June (59.44 +/- 5.83 mm3) and reached its maximum (84.43 +/- 8.52 mm3) in November after 42.2% increase (p < 0.01). Mean values of RI were lowest between September and March, increasing significantly (p < 0.01) in April (+53%) reaching highest value in June (0.564 +/- 0.158). From the lowest value recorded in October through February, the average PI values increased significantly (p < 0.05) in March (+41%) to reach maximum value in July (0.940 +/- 0.368). In parallel with the substantial decrease in Doppler measurements, all parameters analyzed during the breeding season (October-March) were positively affected. In conclusion, the monthly definite changes in the studied parameters evidenced three novel findings: (1) plasma testosterone concentration, which increased significantly (p < 0.05) at late summer (August), was the potential initiator for resuming the breeding season in rams via triggering spermatogenic activity and maximum testicular volume during this period, (2) resulting values of testicular volume and testicular blood flow profiles all year round provide useful reference values for predicting testicular function in rams, (3) the marked increase in testicular blood flow volume, i.e. remarkable decrease in both RI and PI values, during the breeding season could be regulated by the marked increase in testicular volume and plasma estradiol -17beta levels during this period. PMID- 30292859 TI - Derivation of chicken primordial germ cells using an indirect Co-culture system. AB - Primordial germ cells (PGCs) are promising genetic resources for avian studies including modified animals. However, chicken PGCs are slow to proliferate and gradually lose germline competency after long-term culture, which hinders their application in avian biotechnology. Thus, we developed a robust method for the isolation and rapid propagation of PGCs using an indirect co-culture system. PGCs derived from a pair of embryonic chicken gonads were expanded to 1 * 106 within 2 weeks, and no sex bias was observed in. These PGCs presented high capacity of germline transmission and produced donor-derived offspring after injection into the chicken embryos. This system allows the efficient gene-banking of chicken species and can facilitate the production of chickens bearing a desired phenotype via genomic editing. PMID- 30292860 TI - Estrous detection by continuous measurements of vaginal temperature and conductivity with supervised machine learning in cattle. AB - This study aimed to evaluate the effectiveness of estrous detection technique based on continuous measurements of vaginal temperature (VT) and conductivity (VC) with supervised machine learning in cattle. The VT and VC of 17 cows in tie stalls were measured using our developed wearable vaginal sensor from Day 11 (Day 0 = ovulation day) to Day 11 of the subsequent estrous cycle at 15-min interval. After the maximum VT and VC were extracted hourly, their changes were expressed as residual VT (rVT = actual VT - mean VT for the same time on the previous 3 days) and as VC ratio (VCr = actual VC/mean VC for the same time on Day 11-13), respectively, and were used for analysis. Trans-rectal ultrasonography was performed to monitor ovarian structure changes. The plasma concentrations of reproductive hormones (progesterone: P4, estradiol-17beta: E2, and LH) were measured in the experimental period. Standing estrus was confirmed by testing with herd mates at 3-h interval. The rVT decreased transiently, which coincided with decreasing P4 a few days before estrus, and a sharp increase was associated with LH surge during estrus. The VCr increased as estrus approached, corresponding with decreasing P4 and increasing E2 and LH. After noise reduction, features, possible to follow-up estrus-associated changes in rVT and VCr, were extracted and used for developing estrous detection models; 9 models were developed with 3 feature sets (features extracted from rVT alone, VCr alone, and combination of rVT and VCr) and 3 machine learning algorithms (decision tree: DT, support vector machine: SVM, and artificial neural network: ANN). Cross validation showed that models using the features from the combination of rVT and VCr showed better performance in terms of sensitivity and precision than those using features from VCr alone, and precision than those of using features from rVT alone. Within the models using the features from the combination of rVT and VCr, sensitivity and precision of the model generated by ANN were numerically, but not statistically, higher than those generated by DT and SVM. Of 17 estruses, 16 were detected, with one false positive, when the best model was used. Furthermore, both mean and variance of the interval from the beginning of the estrous detection alert to ovulation (27.3 +/- 6.7 h, mean +/- SD of 16 estruses) were not significantly different to those from the onset of standing estrus to ovulation (30.8 +/- 5.8 h, n = 17), indicating that the estrus can be detected real-time by the present technique. Hence, the estrous detection technique based on continuous measurements of VT and VC with supervised machine learning has a potential for efficient and accurate estrous detection in cattle. PMID- 30292861 TI - A novel tool to evaluate the implant position and predict defibrillation success of the subcutaneous implantable cardioverter-defibrillator: The PRAETORIAN score. AB - BACKGROUND: Suboptimal positioning of the subcutaneous implantable cardioverter defibrillator (S-ICD) increases the defibrillation threshold and risk of conversion failure. OBJECTIVE: Our objective is to develop a tool to evaluate the implant position and predict defibrillation success of the S-ICD: the PRAETORIAN score. METHODS: The PRAETORIAN score is based on clinical and computer modeling knowledge of determinants affecting the defibrillation threshold: subcoil fat, subgenerator fat, and anterior positioning of the S-ICD generator. The score evaluates these determinants on the postoperative anterior-posterior and lateral chest radiographs and has 3 categories: 30-<90 points representing a low risk, 90 <150 points representing an intermediate risk, and >=150 points representing a high risk of conversion failure. The score was developed using 2 separate S-ICD data sets for derivation and validation. The performance metrics are the positive and negative predictive values. RESULTS: The development data set consisted of 181 patients with S-ICD, and the validation cohort consisted of 321 patients from the S-ICD Investigational Device Exemption trial. The distribution of scores was 93%-98% low risk (<90 points), 2%-5% intermediate risk (90-<150 points), and 1% high risk (>=150 points). The positive predictive value for an intermediate or high PRAETORIAN score for a failed conversion test was 51%, while a low PRAETORIAN score predicted a successful conversion in 99.8% of patients. CONCLUSION: The PRAETORIAN score allows the identification of patients with high defibrillation thresholds by using the routine chest radiograph and provides feedback to implanters on S-ICD positioning. The PRAETORIAN-DFT trial will prospectively validate the score by randomizing to standard conversion testing vs using the score without conversion testing. PMID- 30292862 TI - Three-dimensional reconstruction and quantification of dislocation substructures from transmission electron microscopy stereo pairs. AB - A great amount of material properties is strongly influenced by dislocations, the carriers of plastic deformation. It is therefore paramount to have appropriate tools to quantify dislocation substructures with regard to their features, e.g., dislocation density, Burgers vectors or line direction. While the transmission electron microscope (TEM) has been the most widely-used equipment implemented to investigate dislocations, it usually is limited to the two-dimensional (2D) observation of three-dimensional (3D) structures. We reconstruct, visualize and quantify 3D dislocation substructure models from only two TEM images (stereo pairs) and assess the results. The reconstruction is based on the manual interactive tracing of filiform objects on both images of the stereo pair. The reconstruction and quantification method are demonstrated on dark field (DF) scanning (S)TEM micrographs of dislocation substructures imaged under diffraction contrast conditions. For this purpose, thick regions (>300 nm) of TEM foils are analyzed, which are extracted from a Ni-base superalloy single crystal after high temperature creep deformation. It is shown how the method allows 3D quantification from stereo pairs in a wide range of tilt conditions, achieving line length and orientation uncertainties of 3% and 7 degrees , respectively. Parameters that affect the quality of such reconstructions are discussed. PMID- 30292863 TI - Bacterial replisomes. AB - Bacterial replisomes are dynamic multiprotein DNA replication machines that are inherently difficult for structural studies. However, breakthroughs continue to come. The structures of Escherichia coli DNA polymerase III (core)-clamp-DNA subcomplexes solved by single-particle cryo-electron microscopy in both polymerization and proofreading modes and the discovery of the stochastic nature of the bacterial replisomes represent notable progress. The structures reveal an intricate interaction network in the polymerase-clamp subassembly, providing insights on how replisomes may work. Meantime, ensemble and single-molecule functional assays and fluorescence microscopy show that the bacterial replisomes can work in a decoupled and uncoordinated way, with polymerases quickly exchanging and both leading-strand and lagging-strand polymerases and the helicase working independently, contradictory to the elegant textbook view of a highly coordinated machine. PMID- 30292864 TI - Use of Virtual Surgical Planning and Virtual Dataset With Intraoperative Navigation to Guide Revision of Complex Facial Fractures: A Case Report. AB - The use of intraoperative navigation has become prevalent in multiple surgical fields, including neurosurgery, orthopedic surgery, spine surgery, and head and neck surgery. In the past decade, its use also has become popular in oral and maxillofacial surgery. Previous studies have suggested the use of intraoperative navigation improves surgical precision and accuracy and decreases intraoperative risks and postsurgical morbidity. This report presents a case in which intraoperative navigation was used for revision and secondary reconstruction of multiple facial fractures. Preoperative virtual surgical planning allowed customization of osteotomies of multiple bony segments and virtual reduction of these segments to their anatomically correct position. Then, the newly reconstructed 3-dimensional virtual computed tomographic dataset was used as a template in the navigation system to guide the osteotomies and precisely reposition bony fragments during surgery. This report describes the workflow necessary to use this technology. PMID- 30292865 TI - Before-after safety analysis using extreme value theory: A case of left-turn bay extension. AB - There is growing interest in the use of traffic conflicts in before and after safety evaluations because of well-recognized quality and quantity problems associated with historical crash records. Most of these studies apply statistical techniques to compare the number of conflicts before and after the implementation of safety countermeasures. However, to identify the number of conflicts, a specific threshold for various conflict indicators needs to be used and the results of the evaluation can vary significantly depending on the selection of this threshold. As well, there is an issue with how to account for conflict severity in the evaluation. This study proposes adopting the extreme value theory approach to overcome these two issues. The approach was applied to a case of left turn bay extension at three signalized intersections, and the automated traffic conflict technique was used to identify conflicts with TTC values from the video data collected from treatment sites and matching control sites. Generalized extreme value (GEV) models with different covariates were developed and compared. The results show that there are apparent shape change in the GEV distribution (i.e., from narrow peak up to high severities to wide spread with fewer conflicts at high severity levels) after the treatment, indicating reduction in conflict severity. The safety improvement is further confirmed by the total reduction of 63.9% in estimated crashes. Moreover, with the aid of GEV model, the most severe conflicts that are also rare and random are included into the OR calculation, and a significant reduction of 73.2% is found in the estimated most severe conflicts. PMID- 30292866 TI - Gaze doesn't always lead steering. AB - In car driving, gaze typically leads the steering when negotiating curves. The aim of the current study was to investigate whether drivers also use this gaze leads-steering strategy when time-sharing between driving and a visual secondary task. Fourteen participants drove an instrumented car along a motorway while performing a secondary task: looking at a specified visual target as long and as much as they felt it was safe to do so. They made six trips, and in each trip the target was at a different location relative to the road ahead. They were free to glance back at the road at any time. Gaze behaviour was measured with an eye tracker, and steering corrections were recorded from the vehicle's CAN bus. Both in-car 'Fixation' targets and outside 'Pursuit' targets were used. Drivers often used a gaze-leads-steering strategy, glancing at the road ahead 200-600 ms before executing steering corrections. However, when the targets were less eccentric (requiring a smaller change in glance direction relative to the road ahead), the reverse strategy, in which glances to the road ahead followed steering corrections with 0-400 ms latency, was clearly present. The observed use of strategies can be interpreted in terms of predictive processing: The gaze-leads steering strategy is driven by the need to update the visual information and is therefore modulated by the quality/quantity of peripheral information. Implications for steering models are discussed. PMID- 30292867 TI - Seatbelt wearing rate in a Chinese city: Results from multi-round cross-sectional studies. AB - OBJECTIVE: Road traffic crashes impose a heavy burden in China's most populous city, Shanghai. Since early 2016, Shanghai police have started deploying high resolution cameras and an object-detection algorithm in seatbelt enforcement. Around the same time, an international consortium on road safety launched a series of capacity trainings for law enforcement accompanied by infrastructure renovation and social marketing campaigns in Shanghai. Our objective is to assess the level and trend of seatbelt use in Shanghai over 2015-2017. METHODS: Ongoing observational studies evaluate seatbelt use within the city. Data are collected at eight randomly selected locations throughout the city, stratified by road type and geographic locations. Data collection covers most times of the day on both business days and weekends, providing a full representation of varying traffic models during both rush hours and non-rush hours. At each site, trained field workers observe seatbelt use of occupants in all passing motorized vehicles. A multivariate logistic regression model was developed to analyze the data. FINDINGS: From October 2015 to December 2017, six rounds of data collection were completed with a total sample size of 77,641 drivers and passengers of motor vehicles. The seatbelt use rate has steadily increased over time, from 60.8% (95% CI: 59.9%-61.7%) in round 1 to 84.9% (84.3%-85.4%) in round 6 (p-value < 0.01). The increase is substantial and statistically significant for both drivers and passengers (p-value < 0.01). Results from the multivariate logistic regression show an annual growth rate of seatbelt use of 8.8% (8.4%-9.1%); the wearing rate was 49.8% (49.0%-50.5%) lower among passengers than drivers; 3.5% (2.9%-4.1%) lower in peri-urban areas than central urban areas; 16.3% (14.3%-18.4%) higher among 18-24-year and 18.9% (17.0%-20.9%) higher among 25-59-year olds than other age groups. CONCLUSION AND POLICY IMPLICATIONS: Seatbelt use in Shanghai has been boosted during a short period of time through a combined strategy that includes training of police, social marketing campaign, and the deployment of computer vision assisted enforcement. Large cities in China and other countries facing similar challenges with seatbelt wearing may learn from Shanghai's experience. PMID- 30292868 TI - Bayesian approach to model pedestrian crashes at signalized intersections with measurement errors in exposure. AB - This study intended to identify the potential factors contributing to the occurrence of pedestrian crashes at signalized intersections in a densely populated city, based on a comprehensive dataset of 898 pedestrian crashes at 262 signalized intersections during 2010-2012 in Hong Kong. The detailed geometric design, traffic characteristics, signal control, built environment, along with the vehicle and pedestrian volumes were elaborately collected. A Bayesian measurement errors model was introduced as an alternative method to explicitly account for the uncertainties in volume data. To highlight the role played by exposure, models with and without pedestrian volume were estimated and compared. The results indicated that the omission of pedestrian volume in pedestrian crash frequency models would lead to reduced goodness-of-fit, biased parameter estimates, and incorrect inferences. Our empirical analysis demonstrated the existence of moderate uncertainties in pedestrian and vehicle volumes. Six variables were found to have a significant association with the number of pedestrian crashes at signalized intersections. The number of crossing pedestrians, the number of passing vehicles, the presence of curb parking, and the presence of ground-floor shops were positively related with pedestrian crash frequency, whereas the presence of playgrounds near intersections had a negative effect on pedestrian crash occurrences. Specifically, the presence of exclusive pedestrian signals for all crosswalks was found to significantly reduce the risk of pedestrian crashes by 43%. The present study is expected to shed more light on a deeper understanding of the environmental determinants of pedestrian crashes. PMID- 30292869 TI - Target-mimicry based diminution of miRNA167 reinforced flowering-time phenotypes in tobacco via spatial-transcriptional biases of flowering-associated miRNAs. AB - Evolutionarily conserved microRNAs such as miR156, miR159, miR167 and miR172 tightly regulate the extensive array of gene expression during flowering in plants, through instant and long-term alterations in the expression of their target genes. Here we employed a novel target-mimicry approach for the diminution of auxin signalling regulator miRNA167 by developing mimic-transgenic lines in tobacco, to investigate the transcriptional biases of flowering-associated miRNAs in apical and floral meristematic tissues and their phenotypic implications. Recorded morpho-alterations such as uneven flowering-time phenotypes, anomalous floral organ formation, and large variations in the seed forming characteristics permitted us to determine the consequence of the extent of miR167 expression diminution accompanying the transcriptional biases of interrelated miRNAs. We demonstrate that percent diminution of miR167 gene expression is proportionally associated with both early and late flowering-time phenotypes in mimic lines. Also, the associated miRNAs, miR156, miR159, and miR172 showed >90% transcriptional diminution in at least 'early-flowering' miR167 mimic lines. On contrary, low percentages of their respective diminution were recorded in 'late flowering' lines. Evidently, the misexpression of miR156, miR159, and miR172 led to the over-expression of their respective target genes SPL9, AtMYB33-like and AP2 genes in mimic lines which resulted in assorted phenotypes. We describe the scope of spatial regulation of these microRNAs in floral bud tissues of mimic lines which showed negative- or very low (<25%) misexpression levels in early/late-flowering lines highlighting their roles in the acquisition of flowering mechanism. To our knowledge, this study represents the first characterization of transcriptional biases of flowering associated miRNAs in miR167-mimic lines and certainly augments our understanding of the importance of microRNA-mediated regulation of flowering in plants. PMID- 30292870 TI - Molecular cloning, characterization and expression analysis of ARMC6, ARMC7, ARMC8 from Pacific white shrimp, Litopenaeus vannamei. AB - Armadillo repeat-containing proteins (ARMCs) comprise a large family that is widely distributed in eukaryotes and plays prominent roles in cell-cell adhesion, intracellular signaling, and cytoskeletal regulation. In this study, three ARMC genes, termed LvARMC6, LvARMC7 and LvARMC8, were identified and characterized from Litopenaeus vannamei. The complete cDNAs open reading frames (ORF) of LvARMC6, LvARMC7, and LvARMC8 (GenBank accession no. MG735126, MG728109 and KX058562) were 1410 bp, 570 bp and 2046 bp, encoding 469, 189, and 681 amino acids, respectively. Topology analysis indicated that three ARM domains were present in LvARMC6, one in LvARMC7 and six in LvARMC8. The identities of all the three LvARMCs with other species were between 50% and 71%. Phylogenetic analysis illustrated that different subtype of ARMCs formed their own separate branches and LvARMCs were placed in branch of invertebrates respectively with strong bootstrap support. The constitutive expressions of LvARMCs were confirmed by real time quantitative PCR. LvARMC6, LvARMC7 and LvARMC8 were expressed highest in heart, gills and epithelium, respectively. After challenge with either white spot syndrome virus (WSSV), Vibrio parahemolyticus, or Staphylococcus aureus, all of the LvARMCs demonstrated differential expression profiles in hemocytes, hepatopancreas, intestine and gills. Taken together, our results suggest that LvARMCs may play a role in the innate immune defense against pathogenic viral and bacterial infections of L. vannamei. PMID- 30292871 TI - Clinical significance of aberrant cyclin-dependent kinase-like 2 methylation in hepatocellular carcinoma. AB - BACKGROUND AND AIMS: Aberrant DNA methylation of cyclin-dependent kinase-like 2 (CDKL2) had been observed in several types of tumors. Herein, the present study was aimed to explore the epigenetic and expression status of CDKL2 and evaluate the diagnostic potential of CDKL2 methylation in hepatocellular carcinoma (HCC). METHODS: The methylation status of CDKL2 was detected by methylation-sensitive restriction enzyme based quantitative PCR (MSRE-qPCR) and bisulfite genomic sequencing (BGS). The mRNA expression of CDKL2 was measured using real-time quantitative PCR (qPCR). The correlations between the methylation of CDKL2 and mRNA expression, clinicopathological features were evaluated. RESULTS: Compared with normal liver tissues, the methylation levels of CDKL2 were significantly increased in the HCC tissues and cell lines (All p < 0.05). And the receiver operating characteristic (ROC) analysis showed that the hypermethylation of CDKL2 had a high specificity and sensitivity to distinguish adjacent non-tumor tissues from HCC tissues. Additionally, the mRNA expression levels of CDKL2 were decreased both in HCC tissues and cell lines than those in normal liver tissues (All p < 0.05), and the expression could be upregulated by 5-aza-2'-deoxycytidine treatment in HCC cell lines. Furthermore, the methylation of CDKL2 was negatively correlated with its mRNA expression (p < 0.001, rs = -0.513), and was associated with gender (p = 0.023), age (p = 0.001) and tumor size (p = 0.016). CONCLUSIONS: Our results showed that CDKL2 promoter hypermethylation played an important role in hepatocarcinogenesis and might be a valuable biomarker for HCC diagnosis. PMID- 30292872 TI - Dual functions of microglia in the formation and refinement of neural circuits during development. AB - Microglia colonize the central nervous system (CNS) parenchyma during embryogenesis and contribute to various developmental processes leading to the formation of refined neural circuits. In this review, we focus on the bidirectional function of microglia during normal CNS development and discuss recent perspectives on the functions of microglia in neural circuit formation. Microglia participate in neurogenesis, migration, axonal growth, and synapse formation and remodeling, all of which are fundamental for the establishment of neural networks, by secreting a variety of molecules toward neurons and phagocytosing both live and dying neurons or their debris. Intriguingly, microglia play dual roles in each of the neurodevelopmental processes that they affect. For instance, microglia modulate synapse numbers by both promoting the formation of new synapses and eliminating unnecessary synapses. The study of the developmental roles of microglia is essential not only for understanding normal CNS development but also for preventing developmental brain disorders caused by microglial dysfunction. PMID- 30292873 TI - Effect of harvest timing on the dynamics of the Ricker-Seno model. AB - The moment of intervention is a key question in harvest programmes and is currently generating an increasing interest. However, little is known about its effect on the population stability. This lack of knowledge is greater in the case of global stability, which is always desirable as it allows to predict the fate of populations regardless of the initial size. Here we use a discrete-time equation to model the dynamics of populations harvested at any time during the reproductive season. We study the effect of the time of intervention on the global stability of populations governed by the Ricker model, which is one of the most relevant models in discrete-time population dynamics. We prove that harvest timing never has a negative effect on the global stability of these populations, extending recent results in the literature. We also study the effect of delayed harvesting on the constancy stability of the controlled populations. PMID- 30292874 TI - Asymptotic stability of delayed consumer age-structured population models with an Allee effect. AB - In this article we study a nonlinear age-structured consumer population model with density-dependent death and fertility rates, and time delays that model incubation/gestation period. Density dependence we consider combines both positive effects at low population numbers (i.e., the Allee effect) and negative effects at high population numbers due to intra-specific competition of consumers. The positive density-dependence is either due to an increase in the birth rate, or due to a decrease in the mortality rate at low population numbers. We prove that similarly to unstructured models, the Allee effect leads to model multi-stability where, besides the locally stable extinction equilibrium, there are up to two positive equilibria. Calculating derivatives of the basic reproduction number at the equilibria we prove that the upper of the two non trivial equilibria (when it exists) is locally asymptotically stable independently of the time delay. The smaller of the two equilibria is always unstable. Using numerical simulations we analyze topologically nonequivalent phase portraits of the model. PMID- 30292875 TI - The effect of affordable daycare on women's mental health: Evidence from a cluster randomized trial in rural India. AB - Access to affordable daycare might improve population mental health. However, evidence is sparse and restricted to middle- and high-income country settings. We conducted a cluster-randomized controlled trial in one low-income setting, rural Rajasthan, India. Communities lacking daycare facilities were identified (n = 160) and randomly selected for assistance in setting up a community-based daycare program (n = 80) or not (n = 80). Women eligible for the daycare program living in these communities completed structured interviews before the intervention (participation rate = 89%) and approximately one year after rollout of the intervention (participation rate = 96%), resulting in a final analytic sample of 3041. Mental distress was measured with the Hindi version of the 12-item General Health Questionnaire (score range: 0-12). We modeled the relation between access to daycare and number of mental distress symptoms (GHQ-12 score) with negative binomial regression using an intention-to-treat approach, which groups women according to if they lived in communities randomized to affordable daycare. We also evaluated the effect of access to daycare on secondary outcomes that may be related to mental distress, including women's work burden, agency, and intimate partner violence (IPV). We found that access to daycare resulted in modest reductions in symptoms of mental distress (mean difference = 0.21, 95% CI: -0.43, 0.02). We found some evidence that daycare reduced IPV, but virtually no change in women's work burden or agency. Our results provide some indication that access to affordable daycare might be one policy lever to improve population mental health. PMID- 30292876 TI - Neighborhood effects on body mass: Temporal and spatial dimensions. AB - Research examining the effects of neighborhood characteristics on obesity and excess body weight has generally neglected the influence of both life-course exposure and geographically-proximate communities. Using data on 9357 respondents to the National Longitudinal Survey of Youth, 1979 Cohort, in conjunction with tract-level data from the 1980-2010 U.S. censuses, this study examines how black, Hispanic, and white individuals' cumulative exposure to varying levels of neighborhood poverty and co-ethnic density from their mid-teens through mid adulthood, as well as the levels of poverty and co-ethnic density in nearby, or "extralocal," neighborhoods, are associated with their body mass index (BMI). Fixed-effect regression models show that, among Hispanics and whites, cumulative exposure to co-ethnic neighbors is a stronger positive predictor of BMI than the co-ethnic density of the immediate, point-in-time neighborhood. Among whites, cumulative exposure to neighborhood poverty is a stronger positive predictor of BMI than is the poverty rate of the current neighborhood of residence. And among both blacks and whites, the distance-weighted poverty rate of extralocal neighborhoods is significantly and inversely related to BMI, suggesting that relative affluence in nearby neighborhoods engenders relative deprivation among residents of the focal neighborhood, leading to increased BMI. Overall, the results suggest that greater attention to both the temporal and spatial dimensions of neighborhood effects has the potential to enhance our understanding of how neighborhoods affect obesity and related health outcomes. PMID- 30292877 TI - Production of bioactive cyclotides in somatic embryos of Viola odorata. AB - Viola odorata L. (Violaceae), an Indian medicinal plant, contains a plethora of cyclotides, which are a class of cyclic peptides derived from plants, possessing several applications. Somatic embryo culture of V. odorata was developed, via indirect somatic embryogenesis, to serve as an alternative to natural plant biomass for sustainable and continuous production of its bioactive ingredients, such as cyclotides. Among the various combinations of phytohormones tested, Murashige and Skoog medium supplemented with 1 mg/l thidiazuron gave rise to the maximum frequency of induction (86.7%) and a high number of somatic embryos (3) from an embryogenic callus. Identification and characterization of cyclotides in the somatic embryos were carried out using a Fourier transform mass spectrometer coupled with liquid chromatography (LC-FTMS). Among the cyclotides identified in the study, few were found to be exclusively present in the somatic embryo culture. Furthermore, the relative abundance of the cyclotides was higher in somatic embryo extract than in the natural plant extract. The biological activities (cytotoxic, haemolytic and antimicrobial) of the somatic embryos and the parent plant were compared. Unlike the natural plants, the somatic embryo extracts demonstrated specificity i.e. they were found to be potent against cancerous cells but not against non-cancerous cell line or red blood cells. In contrast to the plant extract, the somatic embryos extracts were found to be potent against Escherichia coli and Staphylococcus aureus. These results suggest that somatic embryos of V. odorata (rich in cyclotides) can be used as an alternative to plant biomass for its therapeutic applications and germplasm conservation. PMID- 30292878 TI - Job satisfaction among critical care nurses: A systematic review. AB - BACKGROUND: Nursing shortages, particularly in critical care units, are a major concern worldwide. Job satisfaction is a key factor associated with the high turnover of critical care nurses. OBJECTIVES: The purpose of this systematic review was to synthesize the evidence on critical care nurses' job satisfaction. Specific research questions were: 1. How is job satisfaction defined and measured in studies of critical care nurses? 2a. What is the level of job satisfaction among critical care nurses? 2b. How has it changed over time? 2c. Do nurses' levels of job satisfaction differ by type of critical care unit? 3. What factors are associated with critical care nurses' job satisfaction? DESIGN: Systematic review. DATA SOURCES: We searched five electronic databases from January 1980 to May 2015: MEDLINE, CINAHL, PsychINFO, EMBASE, and Proquest Nursing & Allied Health Source. REVIEW METHODS: Two team members independently screened all titles and abstracts and extracted data and assessed methodological quality on all included papers. A narrative synthesis with vote counting was undertaken. RESULTS: A total of 1995 titles were identified, of which 61 satisfied our inclusion criteria. Only 24 (39%) of the included studies reported a conceptual definition of job satisfaction. Forty-two different quantitative measures of job satisfaction were identified, of which only 10 (24%) were used in multiple studies. The weighted mean job satisfaction score for critical care nurses across all studies was 56% satisfied and demonstrated fluctuations over time. Four factors showed significant positive relationships to job satisfaction: 1. shift worked - rotating 8- to 12-h and rotating days, evenings or nights; 2. Autonomy; 3. personnel resources and staffing; and 4. teamwork and cohesion; while two factors showed significant negative relationships to job satisfaction: 1. job stress; and 2. burnout-emotional exhaustion. CONCLUSION: From this review, we did not find any evidence to support relationships between individual (socio demographic) factors and critical care nurses' job satisfaction. We did however find evidence to support relationships between several employment and organizational factors and job satisfaction. Several of these factors are different from those reported among general hospital nurses and long-term care nursing staff, supporting the need for differential strategies to improve critical care nurses' job satisfaction. While the findings from this review hold promise as potential targets of future job satisfaction interventions, there were several methodological problems inherent in many of the studies. PMID- 30292879 TI - Tumor necrosis factor receptor superfamily members 1a and 1b contribute to exacerbation of atherosclerosis by Chlamydia pneumoniae in mice. AB - The host immune responses that mediate Chlamydia-induced chronic disease sequelae are incompletely understood. The role of TNF-alpha, TNF receptor 1 (TNFR1), and TNF receptor 2 (TNFR2), in Chlamydia pneumoniae (CPN)-induced atherosclerosis was studied using the high-fat diet-fed male C57BL/6J mouse model. Following intranasal CPN infection, TNF-alpha knockout (KO), TNFR1 KO, TNFR2 KO, and TNFR 1/2 double-knockout, displayed comparable serum anti-chlamydial antibody response, splenic antigen-specific cytokine response, and serum cholesterol profiles compared to wild type (WT) animals. However, atherosclerotic pathology in each CPN-infected KO mouse group was reduced significantly compared to WT mice, suggesting that both TNFR1 and TNFR2 promote CPN-induced atherosclerosis. PMID- 30292880 TI - Relationship between genome packaging and Gag translation/AUG of primate lentiviruses. AB - About the relationship between retroviral genome packaging and translation, three possible modes (random-, trans-, and cis-) of packaging process could be assumed. In this report, we developed an assay system based on the RT-qPCR to measure the packaging efficiency of primate lentiviruses. With this system, we analyzed the genome packaging modes of primate lentiviruses such as HIV-1, 2, SIVmac and SIVagm. The data suggested that the modes of all viruses analyzed were very similar. In addition, we observed that the Gag-AUG sequences of them played important roles for maintaining efficient packaging, other than the initiation of translation.

AB - Peripheral blood mononuclear cells (PBMC) were collected from a 70-year old Parkinson Disease patient. The PBMCs were reprogrammed with the human OKSM transcription factors using the non-integrating episomal vector system. The transgene-free iPSC showed pluripotency verified by immunocytochemistry for pluripotency markers and differentiated directly toward the 3 germ layers in vitro. Furthermore, the iPSC line showed normal karyotype. PMID- 30292882 TI - Generation of an induced pluripotent stem cell (iPSC) line from a patient with developmental and epileptic encephalopathy carrying a KCNA2 (p.Leu328Val) mutation. AB - Mutations in the KCNA2 gene, coding for the voltage-gated K+ channel Kv1.2, can cause developmental and epileptic encephalopathies. Kv1.2 channels play an important role in the repolarization phase of an action potential in nerve cells. Here, we reprogrammed human skin fibroblasts from a 13-year-old male patient with developmental and epileptic encephalopathy carrying a point mutation (c.982T>G, p.Leu328Val) in KCNA2 to human induced pluripotent stem cells (iPSCs) (HIHDNEi001 A). The cells maintained a normal karyotype and their pluripotency state was verified by the expression and staining of several pluripotency markers and capability to differentiate into all three germ layers. PMID- 30292883 TI - Urine collection methods for non-toilet-trained children in biological monitoring studies: Validation of a disposable diaper for characterization of tebuconazole exposure. AB - Young children differ from adults in their exposure and susceptibility to environmental chemicals (e.g. pesticides) because of various factors such as behavior, diet and physiology. Their heightened vulnerability to environmental stressors makes it important to obtain appropriate urine samples for exposure characterization. However, collecting urine from non-toilet-trained children has been shown to be methodologically and practically challenging. Four urine collection approaches were tested: a disposable diaper, a urine bag, a collection pad and the clean catch. The success rate and the user rating of each method was evaluated. The success rates were 67%, 21%, 17% and 4% for the disposable diaper, urine bag, collection pad and clean catch, respectively. The average user ratings on a 0-10 (0 = inconvenient, 10 = convenient) scale were 9.0, 4.7, 7.3 and 2.5, respectively. Subsequently, the best rated method, the disposable polyacrylate diaper was tested with hydroxy-tebuconazole as an exposure biomarker for the fungicide tebuconazole and creatinine for urine density adjustment. After LC MS/MS analysis, the recoveries of hydroxy-tebuconazole in the range of 0.05-25 ng/mL were on average 106%, and for creatinine 87%. Precisions (relative standard deviation) were for both 3%. The overall procedure including collection and extraction was assessed, resulting in three out of seven positive samples. Based on this study, the disposable diaper is a suitable method for urine collection of non-toilet-trained children for biomonitoring of tebuconazole. This method can serve as a basis for extension to other substances of interest. PMID- 30292885 TI - Characterization of acute intrastriatal effects of paraoxon on in vivo dopaminergic neurotransmission using microdialysis in freely moving rats. AB - Paraoxon (POX) is an extremely neurotoxic organophosphorous compound (OP) which main toxic mechanism is the irreversible inhibition of cholinesterase. Although the cholinergic system has always been linked as responsible for its acute effects, experimental studies have suggested that the dopaminergic system also may be a potential target for OPs. Based on this, in this study, the acute intrastriatal effects of POX on dopaminergic neurotransmission were characterized in vivo using brain microdialysis in freely moving rats. In situ administration of POX (5, 25 and 50 nmol, 60 min) significantly increased the striatal dopamine overflow (to 435 +/- 79%, 1066 +/- 120%, and 1861 +/- 332%, respectively), whereas a lower concentration (0.5 nmol) did not affect dopamine levels. Administration of POX (25 nmol) to atropine (15 nmol) pretreated animals, produced an increase in dopamine overflow that was ~63% smaller than those observed in animals not pretreated. Administration of POX (25 nmol) to mecamylamine (35 nmol) pretreated animals did not significantly affect the POX induced dopamine release. Our results suggest that acute administration of POX increases the dopamine release in a concentration-dependent way, being this release dependent on acetylcholinesterase inhibition and mediated predominantly by the activation of striatal muscarinic receptors, once the muscarinic antagonist atropine partially blocks the POX-induced dopamine release.

PMID- 30292884 TI - Role of body composition and physical activity on permethrin urinary biomarker concentrations while wearing treated military uniforms. AB - Wearing of permethrin treated clothing is becoming more prevalent in military and outdoor occupational and recreational settings, as a personal protection measure against vector borne diseases transmitted through arthropods (e.g., malaria, Lyme disease). The goal of the study was to prospectively examine permethrin exposure among new U.S. Army recruits who had just been issued permethrin-treated uniforms over a 10-week military training period and whether individual body composition (percent body fat, %BF) and physical workload (total energy expenditure, TEE) influenced the exposure. Exposure was assessed by quantification in urine of three permethrin metabolites, 3-phenoxybenzoic acid (3-PBA), and cis- and trans-3 (2,2-dichlorovinyl)-2,2-dimethylcyclopropane-1-carboxylic acid. Although there was individual variability, urinary concentrations and estimated dose levels decreased over the 10-week period. Mixed models demonstrated that 10% higher %BF was significantly associated with 4.42% higher 3-PBA concentrations and a 10% higher daily TEE was significantly associated with a 10.57% higher 3-PBA concentrations. Additional factors influencing exposure included sex, number of uniform launderings, and wear- time (hours per previous day).

AB - Fistulizing complications develop in approximately one third of patients with Crohn's disease (CD), resulting in morbidity and impaired quality of life.1 Sites of fistulae most commonly include perianal fistulae, but also enterocutaneous, enteroenteric, enterovesical, and rectovaginal. Its management requires combined medical and surgical strategies to prevent abscess formation and induce healing. Biologic agents have improved the medical treatment of CD-related fistulae, but many patients still require surgical intervention. Hence, there is considerable interest in the development of novel pharmaceutical agents to treat fistulizing CD. PMID- 30292888 TI - The Gut-Brain Axis and the Microbiome: Mechanisms and Clinical Implications. AB - BACKGROUND & AIMS: Based largely on results from preclinical studies, the concept of a brain-gut microbiome axis has been established, mediating bidirectional communication between the gut, its microbiome, and the nervous system. Limited data obtained in human beings suggest that alterations in these interactions may play a role in several brain-gut disorders. METHODS: We reviewed the preclinical and clinical literature related to the topic of brain-gut microbiome interactions. RESULTS: Well-characterized bidirectional communication channels, involving neural, endocrine, and inflammatory mechanisms, exist between the gut and the brain. Communication through these channels may be modulated by variations in the permeability of the intestinal wall and the blood-brain barrier. Brain-gut microbiome interactions are programmed during the first 3 years of life, including the prenatal period, but can be modulated by diet, medications, and stress throughout life. Based on correlational studies, alterations in these interactions have been implicated in the regulation of food intake, obesity, and in irritable bowel syndrome, even though causality remains to be established. CONCLUSIONS: Targets within the brain-gut microbiome axis have the potential to become targets for novel drug development for brain-gut disorders. PMID- 30292889 TI - Low Rates of Linkage and Retention Into Care Among Patients With Chronic HBV Infection. AB - Successful linkage and retention of newly diagnosed hepatitis B virus (HBV) patients is critical for disease monitoring. Existing studies have demonstrated significant gaps in the HBV care continuum among U.S. veterans1 and have mostly focused on adherence to laboratory testing or initial linkage. However, retention is especially important, given that decisions to start antiviral therapies are often not made until subsequent evaluation, and studies report high rates of becoming treatment-eligible among patients who were not eligible at initial evaluation.2 Given the existing system and socioeconomic barriers in access to care, understanding contributors to gaps and delays in HBV linkage and retention among safety-net populations is critical. We aim to evaluate prevalence and predictors of linkage and retention among HBV patients at an urban safety-net hospital. PMID- 30292890 TI - Unlocked potential of dynamic elements in protein structures: channels and loops. AB - Enzymes are nature's powerful catalytic proteins to perform reactions with often outstanding activity, selectivity and specificity. Moreover, the access to non natural functions of biocatalysts can be facilitated by enzyme engineering. While rational approaches are often focused on an enzyme's active site, from random directed evolution we know that further functional hotspots must exist beyond the active site. Addressing flexible structural elements of these biocatalysts like loops and channels in enzyme engineering has the potential to fill this knowledge gap. The structural dynamics of enzyme catalysts are vital to promote their remarkable functions. This influences for example the access, recognition and orientation of substrates. Herein, we review recent examples of loop and channel engineering and classify them according to their use of simulation methodologies, predictions prior to engineering, the engineering methodologies themselves and discoveries found after the engineering. Thereby we highlight current possibilities and make suggestions to further unlock the potential of this yet underexplored strategy. PMID- 30292891 TI - Does the use of adjunct urine LAM in HIV-infected hospitalized patients reduce the utilization of health care resources? A post hoc analysis of the LAM multi country randomized control trial. AB - BACKGROUND: The World Health Organisation (WHO) recommends the use of adjunctive urine lipopolysaccharide lipoarabinomannan (LAM) testing in hospitalized HIV infected persons with suspected tuberculosis (TB) and a CD4 count <100 cells/ml. However, the recommendation is conditional and uptake by individual treatment programs depends on perceived additional benefit. The aim of this study was to determine if adjunctive LAM testing had additional clinical benefits including reduction in health care-related use of resources. METHODS: We performed a post hoc analysis of a published multicenter multinational randomized control trial that showed an ~20% mortality benefit in HIV-infected hospitalized patients who underwent adjunctive LAM testing as part of their diagnostic workup. In that parent study adult HIV-infected hospitalized patients with suspected TB (n=2528) were randomly allocated to either routine diagnostics (smear-microscopy, Xpert MTB/RIF, and culture; n=1271), or routine diagnostics plus adjunctive urine LAM testing (n=1257). Data were further analyzed to determine if there were other potential benefits of LAM usage based on CD4 count and illness severity. Aspects evaluated included: (i) reduction in the number of diagnostic sputum samples tested, (ii) utilization of additional imaging, (III) disease resolution based on follow-up signs and symptoms of illness severity, and (IV) reduction in hospital readmission. RESULTS: Adjuvant LAM did not reduce the number of diagnostic sputum samples requested, the need for additional imaging, or the hospital readmission rate. However, adjunctive LAM was associated with a more rapid rate of disease resolution (dyspnea) in the severely ill subgroup. Higher LAM grade (grade 4-5), compared to lower grade positivity (<=3), was associated with lower use of ultrasound, lower Karnovsky performance score, lower CD4 cell count, and shorter time to culture positivity. CONCLUSIONS: Although, in the parent study adjunct LAM was associated with a mortality benefit, in the secondary analysis, no benefit could be demonstrated with respect to the number of diagnostic sputum samples requested, the use of additional imaging, or hospital readmission rates. However, given the limitations of the present study, further appropriately designed studies are required to determine the effect of adjunct urine LAM on utilization of health care resources. TRIAL REGISTRATION: This trial is registered with ClinicalTrials.gov, number NCT01770730. PMID- 30292892 TI - The impact of earlier intervention by an antimicrobial stewardship team for specific antimicrobials in a single weekly intervention. AB - OBJECTIVE: The objective of this study was to evaluate the effects of earlier intervention by an antimicrobial stewardship team (AST) on antimicrobial use, antimicrobial resistance rates, and the clinical outcomes, without changing the weekly intervention schedule. METHODS: A retrospective study was conducted at Fukuoka University Hospital between April 2013 and March 2016. The effects were compared among three study periods (SP): SP1 (patients receiving anti-methicillin resistant Staphylococcus aureus agents and carbapenems for >=14 days), SP2 (patients receiving specific antimicrobials for >=14 days), and SP3 (patients receiving specific antimicrobials regardless of the duration of treatment). RESULTS: The timing of AST intervention was shortened from an average of 15.5days after administration in SP1 to 4.2 days in SP3. The antimicrobial use density (AUD) of carbapenems and piperacillin-tazobactam decreased significantly (SP2 vs. SP3, p<0.05), and the costs of specific antimicrobials decreased (SP1, US$ 1080000; SP2, US$ 944000; SP3, US$ 763000). The rates of carbapenem resistance among Pseudomonas aeruginosa isolates showed a significant reduction from 16.2% in SP2 to 8.7% in SP3 (p<0.05). The mortality rate and length of stay did not change during the study period. CONCLUSIONS: Earlier intervention by an AST could contribute to the proper use of antimicrobials without adversely affecting patient outcomes. PMID- 30292893 TI - Towards a better understanding of dry binder functionality. AB - It is of great importance to get a deeper understanding of the binding behaviour and functionality of different types of dry binders, since dry binders are crucial to ensure appropriate properties of dry granules and tablets. Based on previous studies, the most effective dry binders of chemically different types have been chosen to apply a new approach analysing the compressibility of tablets made from pure dry binders. Therefore, tablets were compressed at different tableting speeds to reveal binding behaviour of dry binders. Viscoelasticity, plasticity or abrasiveness were derived from force-displacement curves of tablets, which were manufactured at varying tableting pressure. In addition, elastic recovery, tabletability, fracture energy and out-of-die Heckel analysis were performed in order to get a comprehensive understanding on mechanical properties of dry binder for tableting. The new approach indicated explanations for results of previous studies in terms of tablet tensile strength, friability and dry granule properties. It enables a rational selection of dry binders for certain processes. PMID- 30292894 TI - Improved oral bioavailability of notoginsenoside R1 with sodium glycocholate mediated liposomes: Preparation by supercritical fluid technology and evaluation in vitro and in vivo. AB - The chief objective of this research was to appraise liposomes embodying a bile salt, sodium glycocholate (SGC), as oral nanoscale drug delivery system to strengthen the bioavailability of a water-soluble and weakly penetrable pharmaceutical, notoginsenoside R1 (NGR1). NGR1-loaded liposomes were prepared with the improved supercritical reverse evaporation (ISCRPE) method and the preparation conditions were optimized with response surface methodology (RSM). The mean encapsulation efficiency (EE), particle size, and polydispersity index (PDI) of the optimized liposomal formulation (NGR1@Liposomes) were 49.49%, 308.3 nm, and 0.229, respectively. SGC-mediated liposomes (NGR1@SGC-Liposomes) were formulated based on the optimal preparation conditions and the mean EE, particle size, and PDI were 41.51%, 200.1 nm, and 0.130, respectively. The in vitro Caco-2 cellular uptake of fluorescent marker was increased by loading into NGR1@SGC Liposomes as compared with the conventional liposomes. Furthermore, the intestinal permeability as well as the intestinal absorption of NGR1 were both significantly improved with NGR1@SGC-Liposomes as the nanovesicles. The in vivo pharmacokinetic study results showed that AUC0-t value of NGR1@SGC-Liposomes and NGR1@Liposomes was 2.68- and 2.03-fold higher than that of NGR1 aqueous solution, respectively. The AUC0-t of the NGR1@SGC-Liposomes group was significantly higher than that of NGR1@Liposomes. Thus, ISCRPE method is a feasible method for the preparation of water-soluble drug-loaded liposomes and bile salt-mediated liposomes may enhance the oral absorption of water-soluble and poorly permeable drugs.

AB - We have previously shown the antioxidant and anti-inflammatory properties of several para-substituted arylnitroalkenes. Since oxidative stress and inflammation are key processes that drive the initiation and progression of atherosclerosis, in the present work the antioxidant, anti-inflammatory and anti atherogenic properties of an extended library of aryl-nitroaliphatic derivatives, including several newly designed nitroalkanes, was explored. The antioxidant capacity of the nitroaliphatic compounds, measured using the oxygen radical absorbance capacity assay (ORAC) showed that the p-methylthiophenyl-derivatives were about three times more effective than Trolox to prevent fluorescein oxidation, independently of the presence or the absence of the double bond next to the nitro group. The peroxyl radical scavenger capacity of the p dimethylaminophenyl-derivatives was even higher, being the reduced form of these compounds even more active. In fact, while the antioxidant capacity of 1 dimethylamino-4-(2-nitro-1Z-ethenyl)benzene and 1-dimethylamino-4-(2-nitro-1Z propenyl)benzene was 4.2 +/- 0.1 and 5.4 +/- 0.1 Trolox Eq/mol, respectively; ORAC values obtained with the ethyl and the propyl derivatives were 10 +/- 1 and 13 +/- 2 Trolox Eq/mol, respectively. The p-dimethylamino-derivatives, especially the nitroalkanes, were also able to prevent LDL oxidation mediated by peroxyl radicals. Oxygen consumption due to the oxidation of fatty acids was delayed in the presence of the dimethylamino substituted compounds, only the alkanes interrupted the chain of lipid oxidations decreasing the rate of oxygen consumption. Although the formation of foam cells in the presence of oxidized-LDL (oxLDL) remained unaffected, the molecules containing the dimethylamino moiety were able to decrease the expression of IL-1beta in LPS/INF-gamma challenged macrophages. PMID- 30292896 TI - Activity-guided development of potent and selective toll-like receptor 9 antagonists. AB - TLR9 is one of the major innate immune receptors expressed in the endosomes of pDCs and B cells in humans. Aberrant TLR9 activation is implicated in several autoimmune and metabolic disorders as well as in sepsis, making this receptor an important therapeutic target, though specific TLR9 antagonists are yet to be available for clinical use. Here we elucidate the importance of specific physiochemical properties through substitution patterns in quinazoline scaffold to achieve potent hTLR9 inhibition at < 50 nM as well as > 600 fold selectivity against hTLR7, another closely related TLR that shares downstream signaling with TLR9 but plays distinct roles in physiology and pathology. Assays were performed using hPBMC and reporter cell lines. Favorable in vitro ADME profile, pharmacokinetics as well as validation in a clinically relevant in vivo TLR9 inhibition efficacy model in mice establish these novel TLR9-antagonists as candidate therapeutic agents in relevant clinical contexts. PMID- 30292897 TI - Synthesis and structure-activity relationship study of arylsulfonamides as novel potent H5N1 inhibitors. AB - H5N1 virus, one subtype of highly pathogenic influenza A virus in human infection, has recently received attention due to its unpredictable and high mortality. In this study, a series of arylsulfonamide derivatives were identified as improved H5N1 inhibitors for the influenza treatment by systematic structure activity relationship investigation. Among them, the most potent H5N1 inhibitor 3h exhibited excellent antiviral activity against H5N1 virus with EC50 value of 0.006 MUM and selectivity index 33543.3. Moreover, the molecular docking of 3h with M2 proton channel protein provides practical way for understanding the inhibition of H5N1 with this kind of compounds. PMID- 30292899 TI - Three years of colorectal cancer screening in Denmark. AB - BACKGROUND: The Danish National Colorectal Cancer Screening Programme was implemented in March 2014 and is offered free of charge to all residents aged 50 74 years. The aim of this study is to compare performance indicators from the Danish National Colorectal Cancer Screening Programme to the recommendations from European Guidelines in order to assure the quality of the programme and to provide findings relevant to other population-based colorectal cancer screening programmes. METHODS: Based on data from the Danish Colorectal Cancer Screening Database, we evaluated all performance indicators for which the European Guidelines provided acceptable level, desirable level or the level from first screening rounds in population-based studies using FIT. RESULTS: All performance indicators were above the acceptable level and/or in line with the level from the first screening round in population-based studies using FIT. Whenever the European Guidelines provided a desirable level for a performance indicator, the Danish National Colorectal Cancer Screening Programme was close to or above this desirable level. CONCLUSIONS: Compared to the European Guidelines, all performance indicators were above the acceptable level and close to the desirable level. Based on these findings, the implementation of the National Danish Colorectal Cancer Screening Programme is considered a success and the programme is hopefully in the process of reducing colorectal cancer morbidity and mortality in Denmark. This study provides relevant information for comparisons to other population-based public service colorectal cancer screening programmes as well as for future revisions of guidelines. PMID- 30292898 TI - In search of constrained FTY720 and phytosphingosine analogs as dual acting anticancer agents targeting metabolic and epigenetic pathways. AB - A series of compounds containing pyrrolidine and pyrrolizidine cores with appended hydrophobic substituents were prepared as constrained analogs of FTY720 and phytosphingosine. The effect of these compounds on the viability of cancer cells, on downregulation of the nutrient transport systems, and on their ability to cause vacuolation was studied. An attempt to inhibit HDACs with some phosphate esters of our analogs was thwarted by our failure to reproduce the reported inhibitory action of FTY720-phosphate. PMID- 30292900 TI - A systematic review of shunt-related extraneural metastases of primary central nervous system tumors. AB - Extraneural metastasis (ENM) of primary central nervous system (CNS) tumors is an uncommon occurrence. Case reports and case series describe ENM after shunting, but this phenomenon has not been well characterized. In this review we aim to better understand the risk factors and clinical implications of ENM associated with shunting. A literature search of cases of ENM related to shunt placement in patients with primary CNS tumors reported through January 2018 was performed using PubMed and Google Scholar. We identified 106 cases of ENM of primary CNS tumors related to shunt placement. The three most common tumor histologies resulting in ENM were germinoma (24%), medulloblastoma (21%), and glioblastoma (11%). Of the patients with ENM, 48% had leptomeningeal spread and 37% had brain or spinal cord metastasis. Mean survival time from shunt placement was 13 months. Ventriculoatrial-shunted cases had higher rates of widespread metastasis and shorter average survival time from shunt placement (2 months) than the average of all types of shunts. Given the known association with ENM, careful consideration should be given to shunt placement in patients with primary CNS tumors, especially germinomas, medulloblastomas, and glioblastomas. Appropriate surveillance should be instituted after shunt placement, and leptomeningeal or neural metastasis should prompt the consideration of potential ENM. When considering distal shunt options, our review suggests that ventriculoatrial shunts should be avoided if possible. For truly obstructive pathologies, the risk of ENM is a further indication to consider other treatment options such as endoscopic third ventriculostomy rather than shunt placement. PMID- 30292901 TI - Physical intensity of stimuli modulates motor inhibition by affecting response selection processes in right inferior frontal regions. AB - Response inhibition is a central aspect of cognitive control. Yet, only recently the role of sensory mechanisms for response inhibition has been addressed and neurophysiological mechanisms are far from being understood. Here we ask in how far the physical intensity of stimuli is a relevant perceptual factor modulating motor inhibitory control. We investigated how different physical (objective) stimulus and the subjectively perceived stimulus magnitude modulated response inhibition and its neurophysiological correlates. To this end we used a somatosensory GO/NOGO task in combination with EEG recordings and applied temporal signal decomposition and source localization methods. The behavioral (false alarm) data clearly demonstrated that response inhibition performance was worse in the subjective and objective stimulation condition as compared to the reference stimulation condition with higher stimulus magnitude. Despite primary perceptual aspects were manipulated, neurophysiological correlates of lower-level perceptual and attentional selection processes did not explain effects on overt response inhibition behavior. Rather, neurophysiological processes at the response selection level were modulated. These were associated with activation differences in the right inferior frontal gyrus and suggest that "braking processes" enabling the inhibition of a to-be-executed motor response were modulated. The modulation of these braking processes depends on objective physical magnitude of incoming sensory information and not the subjectively perceived stimulus magnitude. PMID- 30292902 TI - Effects of cognitive judgement bias and acute antidepressant treatment on sensitivity to feedback and cognitive flexibility in the rat version of the probabilistic reversal-learning test. AB - Depressive disorders are often associated with cognitive biases. In this study, we investigated, in an animal model, whether cognitive judgement bias, measured as a stable and enduring behavioural trait, could modulate the effects of antidepressant drugs on other cognitive processes associated with depression. For this purpose, we identified rats displaying 'pessimistic' and 'optimistic' traits in a series of ambiguous-cue interpretation (ACI) tests. Subsequently, in the preclinical version of the probabilistic reversal-learning (PRL) test, allowing multiple reversals within a test session, we compared the effects of acute administration of 5 different antidepressant (AD) drugs (agomelatine, escitalopram, clomipramine, mirtazapine and venlafaxine) on cognitive flexibility and sensitivity to positive/negative feedback in optimistic and pessimistic animals. We report that, following acute treatment with agomelatine, the proportion of lose-shift behaviours in the PRL test was significantly reduced in pessimistic animals compared to optimists. We also demonstrate that acute treatment with another antidepressant drug, mirtazapine, significantly increased the sensitivity of rats to positive feedback, as indexed by the increased proportion of win-stay behaviour following probabilistic reward. This effect was independent of cognitive bias and was associated with a reduced number of reversals made by the animals. Three other tested drugs had no significant effects on behavioural measures assessed in our study. PMID- 30292903 TI - rTMS pre-treatment effectively protects against cognitive and synaptic plasticity impairments induced by simulated microgravity in mice. AB - During space flight, microgravity has several negative effects on cognitive functions and learning and memory abilities. However, there are few effectively preventive methods that have been developed yet. Previous studies showed that repetitive transcranial magnetic stimulation (rTMS), as a novel non-invasive technique, alleviated cognitive dysfunctions and facilitated synaptic plasticity. In the present study, we used a hindlimb unloading (Hu) mouse model to simulate microgravity conditions. And then, we investigated whether rTMS played a neuroprotective role in a Hu mouse model. Behavioral experiments including Open field test and Novel object recognition test were performed. These results showed that spontaneous activity and recognition memory were reduced by Hu, while rTMS significantly protected against the harmful effect. Furthermore, electrophysiological recordings were performed to examine the level of synaptic plasticity including paired-pulse facilitation (PPF) and long-term potentiation (LTP). In the hippocampus DG and CA1 regions, dendritic spine density was measured using Golgi-Cox staining. Our data showed that rTMS effectively impeded the impairment of PPF and LTP, as well as the decrease of spine density induced by Hu. Subsequently, Western blot assay showed that rTMS inhibited the downregulation of CREB/BDNF signaling network associated proteins in Hu mice. It suggests that rTMS pre-treatment plays a neuroprotective role in protecting against cognitive impairments and synaptic plasticity deficits induced by microgravity stimulation.

PMID- 30292905 TI - Use Side Branch of the Aortic Graft to Facilitate Coronary Reconstruction During Complex Aortic Surgery. AB - The interposition graft could be used for difficult coronary reconstruction during aortic root replacement. We introduced a new technique that utilizes side branch of an aortic graft to facilitate coronary reconstruction. The present study describes this technique and its outcomes. We retrospectively reviewed 234 patient charts of those who underwent aortic root replacement between January 2013 and November 2017. Within this group, 6 patients required coronary reconstruction with branches of aortic graft and were included in this study. All patients were reoperative cases, 3 of which were for acute type A aortic dissection. The mean cardiopulmonary and aortic cross clamp times were 317.2 +/- 35.1 minutes and 153.3 +/- 75.4 minutes, respectively. All patients survived to discharge with a median hospital stay of 20.5 days (interquartile range: 13.75 27.75). During a median follow-up of 221 days (interquartile range: 197.78-1208), no patients experienced major adverse cardiovascular events. Four patients underwent radiographic follow-up, which confirmed patent interposition grafts (5/5). The use of branches from the aortic graft for coronary reconstruction is feasible with satisfactory outcomes. PMID- 30292906 TI - Raman investigation of the pigment families in recent and fossil brachiopod shells. AB - Shells of the three subphyla of extant and extinct representatives of the phylum Brachiopoda display coloured patterns with diverse shapes and at different degrees. These colourations are readily visible in natural light but are best revealed under UV light for the fossils concerned. To identify these pigments, Raman spectroscopy has been used for the first time on brachiopod shells. The widespread identified pigments belong to the carotenoid family, best represented in all the animal kingdom, the second one concerns the melanin/melanin-like pigments and, surprisingly, additional molecules of the cytochrome family are revealed for the first time in one of the brachiopod shells studied. The putative functions of shell pigmentation, still under debate, are discussed. PMID- 30292907 TI - Fourier transform infrared spectroscopy based spectral biomarkers of metastasized breast cancer progression. AB - Breast cancer is a global health issue and the second leading cause of cancer death in women. Breast cancer tends to migrate to bone and causes bone metastases which is ultimately the cause of death. Here, we report the use of FTIR to identify spectral biomarkers of cancer progression on 3D in vitro model of breast cancer bone metastasis. Our results indicate that the following spectral biomarkers can monitor cancer progression, for example, lipids (CH2 asymmetric/CH2 symmetric stretch), Amide I/Amide II, and RNA/DNA. Principal component analysis also confirmed the involvement of protein, lipids and nucleic acids in cancer progression on sequential culture. The collective observations from this study suggest successful application of FTIR as a non-invasive and accurate method to identify biochemical changes in cancer cells during the progression of breast cancer bone metastasis. PMID- 30292908 TI - An evidence of chemically and physically mediated migration of 238U and its daughter isotopes in the vicinity of a former uranium mine. AB - The present study reports the evidence of a radioactive contamination in a wetland located downstream from a former French U mine in Brittany. This situation is demonstrated according to the measurements of gamma dose rates and activity ratios of 238U and 232Th-decay series nuclides, which give the justification regarding the accumulation of significant amounts of 238U, 230Th and 226Ra in this wetland. The dose rate map highlights an increase of radiation level along the former mine water pathway compared to the background value, with a maximum value of 1500 nSv.h-1 reached in the wetland. Activities of 238U, 230Th and 226Ra and 232Th/238U ratios measured in surface wetland soils are significantly higher than the geochemical background. 230Th/238U ratios less than unity suggest a preferential accumulation of U in the wetland, compared to its daughter isotopes. Moreover, the loss of 226Ra compared to 230Th raises its higher mobility compared to its parent isotope. In far-field sediments, 226Ra/238U ratio of 1.76 implies a different geochemical behavior of U, which could be explained by the occurrence of mobile U species. The results suggest that contamination of wetland soils and far-field sediments could result from discharges of underground mine waters. PMID- 30292909 TI - Meteorological and soil surface effects in gamma radiation time series - Implications for assessment of earthquake precursors. AB - Monitoring of environmental radioactivity for the purpose of earthquake prediction requires the discrimination of anomalies of non-tectonic origin from seismically-induced anomalies. This is a challenging task as time series of environmental radioactivity display a complex temporal pattern reflecting a wide range of different physical processes, including meteorological and surface effects. The present study is based on the detailed time series of gamma radiation from the Eastern North Atlantic (ENA) site in the Azores, and on very high resolution precipitation intensity and soil moisture time series. The results show that an abrupt shift in the average level of the gamma radiation time series previously reported as a potential earthquake precursor can also be explained by a corresponding abrupt change in soil moisture. It was concluded that the reduction of false positive earthquake precursors requires the detailed assessment of both precipitation and soil moisture conditions at high temporal resolution. PMID- 30292910 TI - SD-CNN: A shallow-deep CNN for improved breast cancer diagnosis. AB - Breast cancer is the second leading cause of cancer death among women worldwide. Nevertheless, it is also one of the most treatable malignances if detected early. Screening for breast cancer with full field digital mammography (FFDM) has been widely used. However, it demonstrates limited performance for women with dense breasts. An emerging technology in the field is contrast-enhanced digital mammography (CEDM), which includes a low energy (LE) image similar to FFDM, and a recombined image leveraging tumor neoangiogenesis similar to breast magnetic resonance imaging (MRI). CEDM has shown better diagnostic accuracy than FFDM. While promising, CEDM is not yet widely available across medical centers. In this research, we propose a Shallow-Deep Convolutional Neural Network (SD-CNN) where a shallow CNN is developed to derive "virtual" recombined images from LE images, and a deep CNN is employed to extract novel features from LE, recombined or "virtual" recombined images for ensemble models to classify the cases as benign vs. cancer. To evaluate the validity of our approach, we first develop a deep-CNN using 49 CEDM cases collected from Mayo Clinic to prove the contributions from recombined images for improved breast cancer diagnosis (0.85 in accuracy, 0.84 in AUC using LE imaging vs. 0.89 in accuracy, 0.91 in AUC using both LE and recombined imaging). We then develop a shallow-CNN using the same 49 CEDM cases to learn the nonlinear mapping from LE to recombined images. Next, we use 89 FFDM cases from INbreast, a public database to generate "virtual" recombined images. Using FFDM alone provides 0.84 in accuracy (AUC = 0.87), whereas SD-CNN improves the diagnostic accuracy to 0.90 (AUC = 0.92). PMID- 30292911 TI - Production of various organic acids from different renewable sources by immobilized cells in the regimes of separate hydrolysis and fermentation (SHF) and simultaneous saccharification and fermentation (SFF). AB - The study was aimed at production of different organic acids (OA) (lactic, fumaric, or succinic) by various microbial cells (filamentous fungi Rhizopus oryzae (F-814, F-1127) and bacteria Actinobacillus succinogenes B-10111) immobilized into poly(vinyl alcohol) (PVA) cryogel from diverse renewable raw materials (wheat and rice straw, aspen and pine sawdust, Jerusalem artichoke stems and tubers, biomass of macro- and microalgae) under batch conditions. The process productivity, bulk output and OA concentrations were higher in case of using immobilized cells than in case of free cells under identical conditions. A higher OA productivity was reached via simultaneous enzymatic saccharification and microbial fermentation (SSF) of same raw materials as compared to their separate enzymatic hydrolysis and fermentation of accumulated reducing sugars (SHF). Maximal concentrations of all OAs studied were obtained for bioconversion of Jerusalem artichoke tubers. The immobilized cells were used in long-term conversion of various renewable materials to OAs in SSF. PMID- 30292912 TI - Biochar influences the succession of microbial communities and the metabolic functions during rice straw composting with pig manure. AB - The present study determined the dynamic changes of bacterial community structures and its metabolism functions in rice straw composting process with different types of biochar addition. Results showed that both wheat and maize straw biochar addition greatly increased the temperatures and germination index. Biochar addition influenced microbial community structure and metabolic characteristics of the compost. Firmicutes, Actinobacteria and Proteobacteria were the dominant phyla throughout the process, and both biochar addition significantly increased the relative abundance of Actinobacteria phylum, especially genus Saccharomonospora. The abundance of bacterial genes related to amino acid metabolism, carbohydrate metabolism and energy metabolism were also increased with biochar addition. Moreover, total nitrogen was strongly affected by biochar addition and had the greatest influence on the bacterial community structure. These results indicated that biochar addition improved the maturity and fertility of the compost product as well as significantly regulated the microbial community structure and functions during composting process. PMID- 30292913 TI - Validation of the stabilometer balance test: Bridging the gap between clinical and research based balance control assessments for stroke patients. AB - BACKGROUND: A pronounced discrepancy exists between balance assessments for stroke survivors that are used for clinical purposes and those used for research. Clinical assessments like the Berg Balance Scale generally have stronger ecological validity, whereas research-based assessments like posturography are generally more reliable and precise. We developed a stabilometer balance test (SBT) that aims to couple measurement reliability and precision to clinical meaningfulness by means of a personalized and adaptive test procedure. RESEARCH QUESTION: To examine the validity, reliability, and measurement error of the stabilometer balance test in inpatient stroke patients. METHODS: In this cross sectional study, inpatient stroke patients (FAC > 2) were tested on a stabilometer with adjustable resistance to mediolateral movement. A modified staircase procedure was used to adapt task difficulty (i.e., rotational stiffness) on a trial-by-trial basis. The main outcome was the threshold stiffness at which a patient could just stay balanced. Threshold stiffness was correlated with the Berg Balance Scale and posturography measurements to determine concurrent validity (N = 86). Test-retest reliability (N = 23) was analyzed with the Intraclass Correlation Coefficient (ICC). Floor and ceiling effects were assessed. The minimal detectable change was determined at individual and group level. RESULTS: Threshold rotational stiffness moderately correlated with the Berg Balance Scale (r=-0.559, p < 0.001), and the absolute path length of the center of pressure during posturography (r=0.348, p = 0.006). Test-retest reliability was good to excellent (ICC=0.869; 95%CI=0.696-0.944). There were no floor or ceiling effects. The minimal detectable change was sufficiently small to detect relevant changes in balance control both on individual and group level. RELEVANCE: The SBT is both a valid and reliable balance assessment in stroke patients. It is at least as precise as current clinically preferred measures and does not suffer from ceiling effects. Therefore, it is suitable for use in clinical practice as well as research. PMID- 30292914 TI - Mechanical work, kinematics, and kinetics during sit-to-stand in children with and without spastic diplegic cerebral palsy. AB - BACKGROUND: Sit-to-stand (STS) is one of the most common fundamental activity in daily life. The pathology of the neuromuscular control system in children with spastic diplegic cerebral palsy (SDCP) could contribute to atypical movement patterns leading to the inefficiency performance including the STS task. However, there was also a lack of evidence about kinematics, kinetics, and especially mechanical work during the STS task in children with SDCP aged 7-12 years old. RESEARCH QUESTION: What were the differences in mechanical work, kinematics and kinetics during STS task between children with SDCP and typically developing (TD) children? METHODS: Eleven children with SDCP (GMFCS I-II) and eleven age and gender-matched control TD children with an age range of 7-12 years were enrolled. Motion analysis and force plate systems were used to collect data. All participants performed the STS task from an adjustable chair. Independent sample t-test and two-way analysis of variance were used in this study. RESULTS: The children with SDCP took a longer time and used more mechanical work during STS than TD children. At the beginning of the STS task, children with SDCP showed more trunk flexion and posterior pelvic tilting; in addition, during the STS task they also presented more trunk, hip, and knee flexion than TD children. However, the children with SDCP showed less ankle dorsiflexion compared with TD children. For the kinetic variables, asymmetry was found in children with SDCP. The maximum hip and knee extension moment, plantar flexion moment, and peak vertical ground reaction force (GRF) of the non-dominant leg were higher than the values of the dominant leg in these children. SIGNIFICANCE: Even though, children with SDCP who are able to independently STS. They were also a mechanically less efficient performance during STS task. Therefore, this task still needs to be trained during rehabilitation sessions.

AB - Human induced pluripotent stem cells (hiPSCs) enable in vitro high-throughput pharmacological screening assays of diseased tissue. Together with recent genome wide association studies (GWAS), hiPSCs enable the identification of key mutations for the development of effective treatments based on precise drugs. In concert with CRISPR/Cas9 systems, hiPSC technology can reveal therapeutic targets in metabolic disorders. The ex vivo CRISPR correction of autologous patient derived hiPSCs has led to the development of replacement cell therapies, providing better patient prognoses.

AB - Chemical-stimuli-responsive nanotherapeutics have gained great interest in drug delivery and diagnosis applications. These nanotherapeutics are designed to respond to specific internal stimuli including pH, ionic strength, redox, reactive oxygen species, glucose, enzymes, ATP and hypoxia for site-specific and responsive or triggered release of payloads and/or biomarker detections. This review systematically and comprehensively addresses up-to-date technological and design strategies, and challenges nanomaterials to be used for triggered release and sensing in response to chemical stimuli. PMID- 30292917 TI - Application of nanotechnology to improve the therapeutic benefits of statins. AB - Hyperlipidemia is defined as an elevated level of lipids and lipoproteins in the blood and is considered to be a significant risk factor for accelerating the process of atherosclerosis and, consequently, cardiovascular disease. The level of cholesterol, especially low-density lipoprotein cholesterol (LDL-C), is commonly elevated in hyperlipidemia and represents the primary therapeutic target. Statins are a group of drugs that function by inhibiting 3-hydroxy-3 methylglutaryl coenzyme A (HMG-CoA) reductase and are extremely efficacious in reducing elevated LDL-C in the serum and preventing atherosclerotic cardiovascular disease. However, statins have some limitations, such as poor aqueous solubility, low oral absorption, and, consequently, limited bioavailability when administered by the oral route. The field of nanotechnology is now well developed and some of these newer nanotechnology strategies offer systems with enhanced aqueous solubility of the statin, increased absorption, bioavailability, and controlled release of the statin at the site of administration. Here, we discuss nano-sized drug delivery systems to enhance the therapeutic potential of statins.

Extant findings suggest that those with AN may rely on heightened recruitment of prefrontal regions during initial formation of food-cue learning and difficulty extinguishing these relationships may result from elevated insula activity. We tested this hypothesis by comparing behavioral and neuronal responses to food-cue acquisition and reversal between adolescents with AN and healthy controls. Compared to controls, acquisition of a food-cue association and its reversal were associated with elevated prefrontal activation in adolescents with AN. There were no significant differences between groups in insula activation and no behavioral differences in the ability to acquire or reverse the food-cue association. The results suggest that adolescents with AN recruit prefrontal regulatory networks to acquire and alter expectancies to food. This pattern of top-down prefrontal control suggests that clinical interventions that target changes in food-cue relationships and rely on cognitive control may be less effective. Interventions that alter behavior without reliance on this top down control may have advantages with this population.

AB - BACKGROUND: Immediate hypersensitivity reactions (HSRs) to taxanes have been increasing in recent years, but the importance of skin tests in allergological workup has not been established. OBJECTIVE: In our study we tried to evaluate the role of prick and intradermal tests in the diagnosis of HSRs to paclitaxel and docetaxel. METHODS: In this multicenter prospective study, we enrolled patients with immediate HSRs to the aforesaid agents. Skin tests were performed on these subjects and if results were negative, intradermal tests with the culprit drug were conducted. Patients with grade 1 reactions subsequently underwent graded challenge; in cases of grade 2 or 3 reactions and/or positive test results, the culprit drug was administered with a desensitization schedule. Skin tests were also performed in 30 control subjects exposed to the taxanes without HSRs. RESULTS: A total of 84 patients (63 with HSRs to paclitaxel and 21 to docetaxel) were recruited in the period July 2015 to July 2017 by 8 centers; 58 patients (69%) developed grade 2 or 3 reactions. Prick test results were negative in all the cases, whereas intradermal test results were positive in 14 patients (10 with paclitaxel [15.9%] and 4 with docetaxel [19%]). The positivity of skin tests significantly correlated with grade 3 reactions and cutaneous involvement during HSRs. Graded challenge was performed in 16 patients without problems and 58 subjects underwent desensitization, which was well tolerated in all but 2 cases. In the control group, skin test results were negative in all the patients. CONCLUSIONS: Skin tests for taxanes seem useful and can be performed in the allergological workup of subjects with HSRs to these agents, especially in cases of severe reactions with cutaneous involvement.

AB - BACKGROUND: Several epidemiological studies have suggested that the risk of depression is increased in patients with asthma, but the impact of asthma during pregnancy on postpartum depression remains unknown. OBJECTIVE: To assess the association between maternal asthma and postpartum depression in a population based cohort study retrieved from administrative databases. METHODS: A cohort of 35,520 pregnancies in women with asthma during pregnancy and 197,057 pregnancies in women without asthma who delivered between 1998 and 2009 was extracted from the Quebec Asthma and Pregnancy Database. They were followed from the day of delivery up to 1 year postpartum. A generalized estimating equation model was used to estimate the adjusted odds ratios of postpartum depression with 95% CIs in women with asthma during pregnancy versus women without asthma. RESULTS: Postpartum depression within 1 year after delivery occurred in 6.1% of women with asthma versus 2.9% of women without asthma. After adjusting for several potential confounders, including depression/postpartum depression up to 10 years before pregnancy, we found that women with asthma were 58% more likely to experience postpartum depression within 1 year after delivery than women without asthma during pregnancy (adjusted odds ratio, 1.58; 95% CI, 1.50-1.67). CONCLUSIONS: Our findings suggest that women with asthma are more likely to suffer from postpartum depression. A close monitoring of signs of depression for pregnant women with asthma is indicated, allowing prompt and efficient interventions if needed.

Change of device may therefore have an impact on clinical and economic outcomes. OBJECTIVE: To characterize clinical and economic asthma outcomes surrounding the change from a dry powder inhaler (DPI) to a pressurized metered-dose inhaler (pMDI) for fixed dose combination inhaled corticosteroid/long-acting beta agonist (FDC ICS/LABA) treatment. METHODS: Three retrospective cohort substudies using 2010 to 2015 data from the Korean Health Insurance and Review Assessment Service database were performed. Patients with asthma who received an FDC ICS/LABA pMDI for the first time after initially being on FDC ICS/LABA DPI were included. The following outcomes were assessed: (1) persistence of change to pMDI over 6 months, (2) clinical outcomes during the year after the change compared with the baseline year; and (3) noninferiority comparison of costs and effectiveness between patients changing to a pMDI and matched patients who continued their DPI. RESULTS: Patients who change inhalers seem to represent a more severe subpopulation. Fifty-eight percent of patients (95% CI, 56-60) persisted with the change. After the change in therapy, an increased proportion of patients (58.3%) remained free from severe exacerbations compared with the year before (47.4%; P < .001). Patients who changed to pMDIs had significantly less severe exacerbations, acute respiratory events, and lower short-acting beta agonist inhaler average daily dose, but higher average ICS daily dose (all P < .05), compared with matched patients remaining on a DPI. Total costs were similar between patients who changed to pMDI therapy compared with those remaining on a DPI. CONCLUSION: Changing from a DPI to a pMDI for FDC ICS/LABA asthma treatment can be as effective and cost-effective as remaining on a DPI.

AB - Tourette syndrome (TS) is a childhood-onset neurological condition characterised by an evolving repertoire of chronic motor tics and one or more phonic tics. Tics, like habits, are inflexible and repetitive behaviours that are acquired over a period of time. It has been proposed that tics arise in TS as a result of increased habit learning: which may bias the child to acquire automatic behaviours (i.e., tics) more readily than is normal and make it harder to unlearn maladaptive habits once they have been acquired. Using a well-established visuomotor adaptation task, we investigated motor learning in a group of children and adolescents with a clinical diagnosis of TS relative to a group of age and gender matched typically developing individuals. In particular, we quantified differences in the strength and quality of motor learning and unlearning in TS, and the consolidation of motor learning over a 24 h washout period. We demonstrated that there was a marginally significant decrease in learning rate in the individuals with TS relative to age and gender matched typically developing controls. However, this effect was not associated with tic severity and could be entirely accounted for by the severity of co-occurring ADHD symptoms. Thus, once ADHD symptoms had been accounted for, there were no between group differences in learning rate or the degree of learning observed. By contrast, and more importantly, we found that following learning the rate of forgetting (unlearning) was significantly negatively associated with motor tic severity, such that individuals with more severe tics took longer to unlearn previously learnt motor patterns of behaviour. This finding is consistent with the proposal that TS is associated with alterations in the striatal habit learning system and with the view that TS may make it harder to unlearn maladaptive motor habits once they have been acquired.

AB - Total chemical synthesis of the linear tetrasaccharide repeating unit beta-D-Glc (1 -> 2)-alpha-L-Rha-(1 -> 3)-alpha-L-Rha-(1 -> 2)-alpha-L-Rha-CH2CH2NH2 of the O antigen from Azospirillum brasilense Jm125A2 is accomplished through rational protecting group manipulations of commercially available monosaccharides and stereoselective glycosylations. The target tetrasaccharide in the form of its 2 aminoethyl glycoside is obtained in ~24% yield over 10 steps following a linear strategy. The structure is particularly suitable for further glycoconjugate formation through the terminal free amine without hampering the reducing end stereochemistry.

AB - A series of eight N1-(2'-O,4'-C-methylene-beta-D-ribofuranonucleoside-3'-yl)-C4 (coumarin-7-oxymethyl)-1,2,3-triazoles have been synthesized by Cu(I)-catalyzed azide-alkyne cycloaddition reaction of 3'-azido-3'-deoxy-2'-O,4'-C methyleneuridine and 3'-azido-3'-deoxy-2'-O,4'-C-methylene-5-methyluridine with 7 propargyloxy coumarins in 82-88% yields. The synthesized coumarintriazolyl bicyclonucleoside conjugates possess an extra bridge between 2'-O and 4'-C in the nucleoside moiety, which facilitates its pre-organization into N-type sugar puckering. This was confirmed by X-ray crystal structure studies on one of the conjugates, i.e. on N1-(3'-deoxy-2'-O,4'-C-methylene-5-methyluridin-3'-yl)-C4-(4 phenylcoumarin-7-oxymethyl)-1,2,3-triazole. Photophysical studies carried out on the synthesized compounds demonstrate that they possess useful level of fluorescence with Stokes shift of approximately 70 nm. PMID- 30292928 TI - Control of autoreactive B cells by IgM and IgD B cell receptors: maintaining a fine balance. AB - A substantial fraction of mature naive B cells recognize endogenous antigens, and this autoreactivity must be controlled to prevent autoantibody secretion. Selective downregulation of the IgM BCR on autoreactive B cells has long been appreciated, and recent findings illustrate how this might impose tolerance. The BCR isotype maintained on autoreactive B cells, IgD, is less sensitive to endogenous antigens than IgM. This reduced sensitivity may be conferred by structural properties of IgD and/or differential association with activating and inhibitory co-receptors. Once activated, autoreactive B cells are normally excluded from rapid plasma cell responses, but they can enter the germinal center and lose their autoreactivity through a mutation-selection process termed clonal redemption. PMID- 30292929 TI - Molecular and histological study on the effects of electrolytic electroporation on the liver. AB - This study examined the temporal physiological and molecular events following the treatment of the liver with a tissue ablation modality that combined electroporation with electrolysis (E2). Rat liver was treated with an E2 waveform and the tissue examined, 1 h, 3 h, 6 h and 24 h with: H&E, Masson Trichrome, TUNEL stains and Western blot. H&E and TUNEL stains have shown that cell death began to be evident 3 h and hepatocyte regeneration was seen 24 h after treatment. H&E and Masson trichrome have shown that the extracellular matrix and the large lumens, appeared intact after E2. Western blot has shown the following molecular events after E2: cleaved caspase 3-downgraded at 1 h, upgraded at 24 h (apoptosis); cleaved Caspase 1 and cleaved GSDMD-upgraded at 6 h (pyroptosis), RIP3-upgraded at 1 h, MLKL-upgraded at 3 h (necroptosis). The mechanism of cell death was possible initiated by necroptosis pathway. Pyroptosis pathway was also activated. The observation that cell death from E2 was by programed necrosis and the details on the temporal molecular pathways, may have value for the recent attempt to combine electroporation mediated ablation with immunological treatment, by demonstrating that the cell death from E2 involves an inflammatory response and by providing data that could be used to design the optimal timing for the injection of immunological adjuvants. PMID- 30292930 TI - Liquid crystals-based sensor for the detection of lithocholic acid coupled with competitive host-guest inclusion. AB - A simple, low-cost and label-free strategy for detecting lithocholic acid (LCA) was designed at the liquid crystals (LCs)/aqueous interface via competitive host guest inclusion. In this method, sodium dodecyl sulfate (SDS) was initially adsorbed on the fluid interface and induced LCs to adopt the homeotropic ordering. Inclusion complexation of SDS and beta-cyclodextrin (beta-CD) disturbed interaction between LCs and SDS and evoked LCs to keep a tilted alignment. When injecting LCA into the mixed solution of SDS and beta-CD, SDS excluded from the cavity of beta-CD by competitive host-guest inclusion and could be re-adsorbed at the LCs/aqueous interface, resulting in the orientational transition of LCs from tilted to homeotropic state. Correspondingly, a bright-to-dark optical response was observed under polarized optical microscope (POM). The as-prepared LCs-based sensor could detect LCA as low as about 2 MUM in aqueous solution. Moreover, the practicability of the approach was validated by monitoring the known amount of LCA in human urine. This work offers an appealing approach for the detection of LCA which has a great potentiality in clinical diagnosis. PMID- 30292931 TI - Hepatocyte culture on 3D porous scaffolds of PCL/PMCL. AB - The development of three-dimensional (3D) porous scaffolds for soft tissue engineering mainly focused on manipulation of scaffold properties with cell behaviors. By emulsion freeze-drying method, four types of porous scaffolds were prepared from amorphous poly(4-methy-epsilon-caprolactone) (PMCL) and semi crystalline poly(epsilon-caprolactone) (PCL) at different weight ratios, named as PMCL0, PMCL30, PMCL50 and PMCL70, respectively. Visual observation on cross sectional images of the scaffolds appeared as sponge-like materials with three dimensional and highly porous morphologies. However, the pore size, porosity and wettability of blends were not decreased linearly with increasing amorphous PMCL. Distinguished from PMCL30 or PMCL70, PMCL50 preserved intact PCL crystals distributed in amorphous matrix, resulting in the lowest Young's modulus (E) and relatively high wettability. From in vitro cell culture, it was observed that PMCL50 scaffold supported human induced hepatocytes (hiHeps) proliferation and function preservation best among all scaffolds. hiHeps on PMCL50 inclined to adopt fibroblastic morphology, whereas formed spheroidal morphology on PMCL0. It was suggested that our bare scaffolds with tailored properties have shown remarkable capability towards hiHep proliferation and function expression. PMID- 30292932 TI - Substrate topography interacts with substrate stiffness and culture time to regulate mechanical properties and smooth muscle differentiation of mesenchymal stem cells. AB - Substrate stiffness and topography are two powerful means by which mesenchymal stem cells (MSCs) activities can be modulated. The effects of substrate stiffness on the MSCs mechanical properties were investigated previously, however, the role of substrate topography in this regard is not yet well understood. Moreover, in vessel wall, these two physical cues act simultaneously to regulate cellular function, hence it is important to investigate their cooperative effects on cellular activity. Herein, we investigated the combined effects of substrate stiffness, substrate topography and culture time on the mechanical behavior of MSCs. The MSCs were cultured on the stiff and soft substrates with or without micro-grooved topography for 10 days and their viscoelastic properties and smooth muscle (SM) gene expression were investigated on days 2, 6 and 10. In general, substrate topography significantly interacted with substrate stiffness as well as culture time in the modulation of cell viscoelastic behavior and SM gene expression. The micro-grooved, stiff substrates resulted in the maximum cell stiffness and gene expression of alpha-actin and h1-calponin, and these values were detected to be minimum in the smooth, soft substrates. The findings can be helpful in the mechano-regulation of MSCs for vascular tissue engineering applications. PMID- 30292933 TI - Towards biomimics of cell membranes: Structural effect of phosphatidylinositol triphosphate (PIP3) on a lipid bilayer. AB - Phosphoinositide (PIP) lipids are anionic phospholipids playing a fundamental role for the activity of several transmembrane and soluble proteins. Among all, phosphoinositol-3',4',5'-trisphosphate (PIP3) is a secondary signaling messenger that regulates the function of proteins involved in cell growth and gene transcription. The present study aims to reveal the structure of PIP-containing lipid membranes, which so far has been little explored. For this purpose, supported lipid bilayers (SLBs) containing 1,2-dioleoyl-sn-glycero-3-phospho-(1' myo-inositol-3',4',5'-trisphosphate (DOPIP3) and 1-palmitoyl-2-oleoyl-sn-glycero 3-phosphocholine (POPC) were used as mimics of biomembranes. Surface sensitive techniques, i.e. Quartz Crystal Microbalance with Dissipation monitoring (QCM-D), Atomic Force Microscopy (AFM) and Neutron Reflectometry (NR), provided detailed information on the formation of the SLB and the location of DOPIP3 in the lipid membrane. Specifically, QCM-D and AFM were used to identify the best condition for lipid deposition and to estimate the total bilayer thickness. On the other hand, NR was used to collect experimental structural data on the DOPIP3 location and orientation within the lipid membrane. The two bilayer leaflets showed the same DOPIP3 concentration, thus suggesting the formation of a symmetric bilayer. The headgroup layer thicknesses of the pure POPC and the mixed POPC/DOPIP3 bilayer suggest that the DOPIP3-headgroups have a preferred orientation, which is not perpendicular to the membrane surface, but instead it is close to the surrounding lipid headgroups. These results support the proposed PIP3 tendency to interact with the other lipid headgroups as PC, so far exclusively suggested by MD simulations.

AB - The present work is an empirical study to check the importance of widely used PRNU extraction de-noising filters at different stages of source camera identification procedure. The proposed work is unique in the sense that it gives an idea about the choice of the appropriate de-noising filters at the time of PRNU extraction for formation of unique identification pattern of digital camera and noise residue extraction of query image. Also in this work, we have suggested the best values of sigma (noise variance) for formation of unique identification pattern of digital camera and noise residue extraction of query image (based on empirical observations). This study has been performed to check that which part (camera unique identification pattern, noise residue, enhancement methods, and value of sigma) mostly dominates the performance of source camera identification. PMID- 30292936 TI - A multifactorial critical appraisal of substances found in drug facilitated sexual assault cases. AB - Drug-facilitated sexual assault (DFSA) is a sexual act in which the victim is unable to give or rescind consent due to intoxication with alcohol and/or drugs that have been self-administered (opportunistic DFSA) or covertly administered by the perpetrator (predatory DFSA). The drugs that are most commonly associated with DFSA are flunitrazepam and gamma-hydroxybutyric acid (GHB). They cause sedation and amnesia, are readily dissolved in beverages and are rapidly eliminated from the system. However, drugs such as amphetamine and cocaine, which are central nervous system (CNS) stimulants, have also been encountered in DFSA cases. This paper critically evaluates trend data from cohort studies, identifying drugs that have been detected in DFSA cases and reports on the differences in drugs used between opportunistic and predatory DFSA. This is the first time that a critical multifactorial review of drugs used in DFSA has been conducted. The pharmacology of each identified group of drugs is presented, showing why these compounds are of interest and used in the perpetration of DFSA. Furthermore, the pharmacology and mechanisms of action are described to explain how the drugs cause their effects. It is also apparent from this study that if meaningful data is to be exchanged between law enforcement agencies then it is necessary to agree on protocols for the collection of evidence and the drugs for which analysis should be performed and indeed on the analytical methods used. PMID- 30292937 TI - A comparative study of different laboratory storage conditions for enhanced DNA analysis of crime scene soil-blood mixed sample. AB - Crime scene investigation is an important step in the entire criminal investigation process because this is where evidence is gathered. Blood from the perpetrator or victim of a crime can be left at crime scenes or transferred to other materials such as clothing, knives and guns. Most often, this body fluid is contaminated with soil at outdoor crime scenes but this might be the only or the most important evidence in solving a crime. This work aimed at identifying the most appropriate method of storing crime scene soil-blood mixed sample prior to analysis at the laboratory. Human blood was mixed with soil and stored at three different storage conditions (i.e., Room temperature/25 degrees C, 4 degrees C and -20 degrees C). Samples stored at room temperature saw significant reduction in DNA concentration as storage time increased (P=0.001). Samples stored at 4 degrees C saw a drastic decrease in DNA concentration just after two weeks of storage. By the eighth week of storage at 4 degrees C, there was no detectable DNA (P=0.000). Samples stored at -20 degrees C recorded no specific pattern in decrease or increase in DNA concentration for the entire 12week storage (P=0.324). There were full STR Profiles generated for room temperature stored samples and -20 degrees C stored samples throughout the study. There were full, partial and null Profiles generated for 4 degrees C stored samples depending on the sample storage duration. In conclusion, -20 degrees C was identified as the best storage condition for soil-blood mixed sample followed by room temperature and 4 degrees C, respectively.

PMID- 30292939 TI - A facile approach for development of a vaccine made of bacterial double-layered membrane vesicles (DMVs). AB - Bacterial infections cause acute and chronic diseases. Antimicrobial resistance and aging-related immune weakness remain challenging in therapy of infectious diseases. Vaccines are however an alternative to prevent bacterial infections. Here we report a facile method to rapidly generate bacterium-membrane-formed nanovesicles as a vaccine using nitrogen cavitation. The vaccine is comprised of double-layered membrane vesicles (DMVs) characterized by cryo-TEM, biochemistry and proteomics, showing DMVs possess the integrity of bacterial membrane and contain a wide range of membrane proteins required for vaccination. In the mouse sepsis model induced by Pseudomonas aeruginosa, we found that DMVs can improve mouse survival after mice were immunized with DMVs. The increased adaptive immunity and unique biodistribution of DMVs were responsible for enhanced protection of bacterial infection. Our studies demonstrate that this simple and innovative approach using nitrogen cavitation would be a promising technology for vaccine developments. PMID- 30292941 TI - Specific discrimination of gram-positive bacteria and direct visualization of its infection towards mammalian cells by a DPAN-based AIEgen. AB - The infections caused by gram-positive bacteria (G+) is a major threat to public health due to their high morbidity and mortality, and the identification of G+ with high sensitivity and selectivity is urgently desirable. In this paper, a probe with aggregation-induced emission (AIE) characteristic is developed and used to discriminate G+ from other bacteria and fungus with excellent selectivity. Thanks for its AIE feature, this probe shows intense fluorescence when interacted with G+, and the signal can last for 24 h after incubating with S. aureus, which is benefit for long term tracing of translocation process with high contrast. Moreover, this probe can be used to visualize the infection processes of G+ towards mammalian cells, which provides valuable information for understanding the therapeutic mechanism. PMID- 30292940 TI - The effects of a functionally-graded scaffold and bone marrow-derived mononuclear cells on steroid-induced femoral head osteonecrosis. AB - Osteonecrosis of the femoral head (ONFH) is a debilitating disease that may progress to femoral head collapse and subsequently, degenerative arthritis. Although injection of bone marrow-derived mononuclear cells (BMMCs) is often performed with core decompression (CD) in the early stage of ONFH, these treatments are not always effective in prevention of disease progression and femoral head collapse. We previously described a novel 3D printed, customized functionally-graded scaffold (FGS) that improved bone growth in the femoral head after CD in a normal healthy rabbit, by providing structural and mechanical guidance. The present study demonstrates similar results of the FGS in a rabbit steroid-induced osteonecrosis model. Furthermore, the injection of BMMCs into the CD decreased the osteonecrotic area in the femoral head. Thus, the combination of FGS and BMMC provides a new therapy modality that may improve the outcome of CD for early stage of ONFH by providing both enhanced biological and biomechanical cues to promote bone regeneration in the osteonecrotic area. PMID- 30292942 TI - Nitric oxide as an all-rounder for enhanced photodynamic therapy: Hypoxia relief, glutathione depletion and reactive nitrogen species generation. AB - A glutathione (GSH)-sensitive supramolecular nitric oxide (NO) nanogenerator is developed as an all-rounder for enhanced photodynamic therapy (PDT). By integrating GSH-sensitive NO prodrug into the system via LEGO-like host-guest interaction, the nanocarrier could not only deplete intracellular GSH, but also relieve hypoxia at tumor sites through NO mediated blood vessel relaxation. Furthermore, reactive nitrogen species (RNS) with enhanced biocidal activity could be produced by the reaction between NO and reactive oxygen species (ROS), generated from alpha-cyclodextrin (alpha-CD) conjugated S-nitrosothiol and light activated chlorin e6 (Ce6) respectively. Due to multiple combined effects between NO and PDT, the NO acts as the loaded gunpowder inside a 'grenade', 'explosively' amplifying the therapeutic effects that the light responsive 'fuse' Ce6 could exert. The present work may well serve as an inspiration for future creative approaches of photodynamic cancer therapy.

AB - INTRODUCTION: The role of parenting behavior is often highlighted in the development of anxiety in youth. However, previous reports are limited in terms of the specificity of relationships between different types of anxiety and parenting behaviors, informant effects on these relationships, and direction of effects. METHODS: This study investigates these questions using longitudinal data from 1350 Swedish adolescents and their parents. Adolescents' self-reports of six dimensions of anxiety and adolescents' and parents' reports of six dimensions of parenting behaviors were used in the analyses. Parallel multiple mediation models were employed to analyze specificity and informant effects within a reciprocal effects model. RESULTS: Overall, and irrespective of informant, this study found little support for a mediating role of parenting behaviors in the relationship between early and late adolescent levels of anxiety. Evidence for specificity within the parenting-anxiety relationship was scarce with specific mediating effects observed only for panic/agoraphobia and total anxiety through the parenting dimension of rejection. CONCLUSIONS: The findings of this study concern the un-conditional mediating role of parenting. Parenting behaviors may be more influential among some adolescents, depending on individual differences in other factors related to the development and course of adolescent anxiety. Thus, further research on moderating factors of the influence of parenting on adolescent anxiety is warranted. PMID- 30292945 TI - Homocysteine causes vascular endothelial dysfunction by disrupting endoplasmic reticulum redox homeostasis. AB - Endothelial dysfunction induced by hyperhomocysteinemia (HHcy) plays a critical role in vascular pathology. However, little is known about the role of endoplasmic reticulum (ER) redox homeostasis in HHcy-induced endothelial dysfunction. Here, we show that Hcy induces ER oxidoreductin-1alpha (Ero1alpha) expression with ER stress and inflammation in human umbilical vein endothelial cells and in the arteries of HHcy mice. Hcy upregulates Ero1alpha expression by promoting binding of hypoxia-inducible factor 1alpha to the ERO1A promoter. Notably, Hcy rather than other thiol agents markedly increases the GSH/GSSG ratio in the ER, therefore allosterically activating Ero1alpha to produce H2O2 and trigger ER oxidative stress. By contrast, the antioxidant pathway mediated by ER glutathione peroxidase 7 (GPx7) is downregulated in HHcy mice. Ero1alpha knockdown and GPx7 overexpression protect the endothelium from HHcy-induced ER oxidative stress and inflammation. Our work suggests that targeting ER redox homeostasis could be used as an intervention for HHcy-related vascular diseases.

AB - STUDY OBJECTIVE: To compare 1.5-Tesla (1.5 T) to 3-Tesla (3 T) Magnetic resonance enterography (MRE) in assessing multifocal (multiple lesions affecting the same segment) and multicentric (multiple lesions affecting several digestive segments) bowel endometriosis in patients with suspected-colorectal endometriosis, in routine practice. STUDY DESIGN: We conducted a retrospective, comparative study in Tenon University Hospital, Paris, France. We included patients scheduled for colorectal resection from April 2014 to February 2018. All patients underwent 1.5 T or 3 T MRE before surgery and endometriosis lesions were confirmed by surgery. The diagnostic performance of 1.5 T and 3 T MRE was evaluated by sensitivity, specificity, positive and negative predictive values (PPV and NPV), accuracy, positive and negative likelihood ratios (LR) and area under the curve of receiver operating curves (AUC ROC). RESULTS: Ninety-eight patients were included. Fifty two (53%) patients presented unifocal lesions, 31 (32%) multifocal lesions, and 23 (24%) multicentric lesions. In assessment of multifocal lesions, the sensitivity, specificity, positive and negative LRs were 0.57 (12/21), 0.89 (23/26), 4.95 and 0.58 for 1.5 T MRE, and 0.10 (1/10), 0.95 (39/41), 2.05 and 0.95 for 3 T MRE. For the diagnosis of multicentric lesions, 1.5 T MRE showed sensitivity, specificity, positive and negative LRs of 0.46 (5 of 11), 0.92 (33 of 36), 5.45 and 0.60 respectively and 3 T MRE showed sensitivity, specificity, and negative LRs of 0.33 (4/12), 1.00 (39/39), and 0.67, respectively. 1.5 T MRE was more accurate than 3 T MRE for diagnosing multifocal lesions (p = 0.02), but there was no difference for multicentric lesion assessment (p = 0.66). CONCLUSION: In routine conditions, 3 T MRE and 1.5 T MRE are of similar low performance for diagnosing multifocal and multicentric bowel endometriosis. PMID- 30292946 TI - The enzyme activity of histone deacetylase 8 is modulated by a redox-switch. AB - Enzymes from the histone deacetylase (HDAC) family are highly regulated by different mechanisms. However, only very limited knowledge exists about the regulation of HDAC8, an established target in multiple types of cancer. A previous dedicated study of HDAC class I enzymes identified no redox-sensitive cysteinyl thiol in HDAC8. This is in contrast to the observation that HDAC8 preparations show different enzyme activities depending on the addition of reducing agents. In the light of the importance of HDAC8 in tumorigenesis a possible regulation by redox signaling was investigated using biochemical and biophysical methods combined with site directed mutagenesis. The occurrence of a characteristic disulfide bond under oxidizing conditions is associated with a complete but reversible loss of enzyme activity. Cysteines 102 and 153 are the integral components of the redox-switch. A possible regulation of HDAC8 by redox signal transduction is suggested by the observed relationship between inhibition of reactive oxygen species generating NOX and concomitant increased HDAC8 activity in neuroblastoma tumor cells. The slow kinetics for direct oxidation of HDAC8 by hydrogen peroxide suggests that transmitters of oxidative equivalents are required to transfer the H2O2 signal to HDAC8.

AB - Direct Oral Anticoagulants (DOACs) available for the treatment and prevention of thromboembolic diseases include dabigatran, a direct thrombin (IIa) inhibitor, and apixaban, edoxaban and rivaroxaban, which are direct inhibitors of Stuart factor (Xa). DOACs have a different pharmacokinetic and pharmacodynamics profiles, with less probable drug-drug interactions than vitamin K antagonists. They do not require systematic therapeutic monitoring except in specific clinical situations such as emergency procedures or drug non-compliance. Furthermore, anticoagulant effects of DOACs could be impacted by renal impairment, drug-drug interactions, food interactions, or pharmacogenetic variability. In this context, we developed a method for simultaneous determination of dabigatran, rivaroxaban and apixaban in human plasma using high performance liquid chromatography coupled with a mass spectrometry assay and applied it to 26 patient samples. Our method presents a total run time of 5 min and extends from 25 to 1000 MUg/L for apixaban and dabigatran; and from 5 to 1000 MUg/L for rivaroxaban. Intra- and inter-assay accuracy were between -22.3 and 25.4%; and - 23.7 and 3.8%, respectively. Precision at low and high concentrations were below 17.5%. Frozen samples were stable up to 3 months. No significant cross-contamination was observed. In conclusion, our assay can be used during clinical studies and in daily routine practice for the management of specific clinical situations at reasonable cost.

AB - Knowledge of the profile of fatty acids, including the profile of long chain fatty acids, is an important parameter for many areas like human health, food sciences, and the study of gene expression in plant tissues, among others. Moreover, very long chain fatty acids occur at low concentrations in many biological samples. The 3-[4-(bromomethyl)phenyl]-7-(diethylamino)coumarin (MPAC Br) reagent is an improved version of the coumarin bromomethyl-type reagents, used for the fluorescent labeling of carboxylic acids in a variety of sample types. Derivatization reactions are always a matter of concern in routine analyses, as they are seen as a time demanding step and a source of errors in analytical chemistry. MPAC-Br is studied in the present work, including the robustness of its derivatization reaction, the stability of its derivatives, the limits of its detection and the repeatability of its results. An optimized version of its protocol was applied to determine the content and profiles of both medium and long chain fatty acids in eight samples of oils and fats. It was shown that the proposed derivatization reaction is a reliable, robust, fast and convenient method for the analysis of these compounds. PMID- 30292950 TI - Development of a parallel microbore hollow fiber enzyme reactor platform for online 18O-labeling: Application to lectin-specific lung cancer N-glycoproteome. AB - We introduce a simple online 18O-labeling protocol for protein samples that uses a parallelizing microbore hollow fiber enzyme reactor (mHFER) as an alternative tool for online proteolytic digestion. Online 18O-labeling is performed by separately attaching two mHFERs in parallel to a 10-port switching valve with a high-pressure syringe pump and two syringes containing 16O- or 18O-water. 16O /18O-labeled peptides are formed in this manner and simultaneously analyzed online using nanoflow liquid chromatography-tandem mass spectrometry (nLC-MS/MS) without any residual trypsin activity. The usefulness of a parallel mHFER platform (P-mHFER) in 18O-labeling was tested using both cytochrome C and alpha-1 acid-glycoprotein to verify the incorporation level of two 18O atoms into tryptic peptides and to provide a quantitative assessment with varied mixing ratios. Additionally, our 18O-labeling approach was used to study the serum N glycoproteome from lung cancer patients and controls to evaluate the applicability of lectin-based quantitative N-glycoproteomics. We successfully quantified 76 peptides (from 62 N-glycoproteins). Nineteen of these peptides from lung cancer serum were up-/down-regulated at least 2.5-fold compared to controls. As a result, the P-mHFER-based online 18O-labeling platform presented here can be a simple and reproducible way to allow quantitative proteomic analysis of diverse proteome samples. PMID- 30292951 TI - Direct recovery of malate dehydrogenase from highly turbid yeast cell homogenate using dye-ligand affinity chromatography in stirred fluidized bed. AB - Dye-ligand affinity chromatography in a stirred fluidized bed has been developed for the rapid recovery of malate dehydrogenase (MDH) from highly turbid baker's yeast cell homogenate in a single step. The most suitable dye, namely Reactive Orange 4, in its optimal immobilized concentration of 8.78 mg/mL was immobilized onto high-density STREAMLINE matrix. To further examine optimal adsorption and elution conditions, the enzyme recovery operation was carried out using unclarified cell homogenates in stirred fluidized bed system. Aiming to develop a non-specific eluent, namely NaCl, to effectively elute the MDH adsorbed, direct recovery of MDH from highly turbid cell homogenate (50% w/v) in a stirred fluidized bed adsorption system was performed. The proposed system successfully achieved a recovery yield of 73.6% and a purification factor of 73.5 in a single step by using 0.6 M NaCl as an eluent at a high liquid velocity of 200 cm/h. PMID- 30292952 TI - Screening bioactive compounds with multi-targets from Rhodiola crenulata by a single column containing co-immobilized beta2-adrenergic receptor and voltage dependent anion channel isoform 1. AB - The pursuit of drugs having improved therapeutic efficacy necessitates increasing research on new assays for screening bioactive compounds with multi-targets. This work synthesized a chromatographic stationary phase containing co-immobilized beta2-adrenergic receptor (beta2-AR) and voltage dependent anion channel isoform 1 (VDAC-1) to achieve such purpose. Specific ligands of the two receptors (e.g. salbutamol, methoxyphenamine, ATP and NADH) were utilized to characterize the specificity and bioactivity of the column. Validated application of the stationary phase was performed by screening multi-target compounds of Rhodiola crenulata using high performance affinity chromatography coupled with ESI-Q-TOF MS. By zonal elution, we identified salidroside as a bioactive compound simultaneously binding to beta2-AR and VDAC-1. The compound exhibited the binding sites of 1.0 * 10-7 and 4.0 * 10-7 M on the beta2-AR and VDAC-1. On these sites, the association constants were calculated to be 3.3 * 104 and 1.0 * 104 M-1. Molecular docking indicated that the binding of salidroside to the two receptors occurred on Ser169 and Phe255of beta2-AR, and the channel wall of VDAC-1. Taking together, we concluded that the column containing co-immobilized receptors has potential for screening bioactive compounds with multi-targets from complex matrices including traditional Chinese medicines. PMID- 30292953 TI - Does articulatory rehearsal help immediate serial recall? AB - Articulatory rehearsal is assumed to benefit verbal working memory. Yet, there is no experimental evidence supporting a causal link between rehearsal and serial order memory, which is one of the hallmarks of working memory functioning. Across four experiments, we tested the hypothesis that rehearsal improves working memory by asking participants to rehearse overtly and by instructing different rehearsal schedules. In Experiments 1a, 1b, and 2, we compared an instructed cumulative rehearsal condition against a free-rehearsal condition. The instruction increased the prevalence of cumulative rehearsal, but recall performance remained unchanged or decreased compared to the free-rehearsal baseline. Experiment 2 also tested the impact of a fixed rehearsal instruction; this condition yielded substantial performance costs compared to the baseline. Experiment 3 tested whether rehearsals (according to an experimenter-controlled protocol) are beneficial compared to a matched articulatory suppression condition that blocked rehearsals of the memoranda. Again, rehearsing the memoranda yielded no benefit compared to articulatory suppression. In sum, our results are incompatible with the notion that rehearsal is beneficial to working memory. PMID- 30292954 TI - New phenolic halogenated disinfection byproducts in simulated chlorinated drinking water: Identification, decomposition, and control by ozone-activated carbon treatment. AB - Recently, 13 new phenolic halogenated disinfection byproducts (DBPs) were discovered and confirmed in chlorinated drinking water using ultra performance liquid chromatography/electrospray ionization-triple quadrupole mass spectrometry (UPLC/ESI-tqMS), which have been attracting a growing concern due to their higher chronic cytotoxicity, developmental toxicity, and growth inhibition compared with commonly known aliphatic DBPs. In this study, another 12 new phenolic halogenated DBPs were detected and identified in simulated chlorinated drinking water samples, including two monohalo-4-hydroxybenzaldehydes, two monohalo-4 hydroxybenzoic acids, three monohalo-salicylic acids, and five mono/di/trihalo phenols. Decomposition mechanisms of these new phenolic halogenated DBPs during chlorination were speculated and partially verified by identifying intermediate products. These new DBPs could undergo hydrolysis, halogenation, substitution, addition, decarboxylation, and rearrangement reactions to form a series of decomposition products, including dihaloacetic acids, 2-halomaleic acids, and a group of new heterocyclic DBPs (trihalo-hydroxy-cyclopentene-diones). A bench scale ozone-granular activated carbon (GAC) treatment unit was designed and set up in the lab. It was found that ozonation and GAC filtration were effective in reducing dissolved organic carbon levels and aromaticity (DBP precursors) of simulated raw water samples, and thus were effective in decreasing the concentrations of these new phenolic DBPs by 82.5% and 88.6%, respectively. Furthermore, four different treatment scenarios (i.e., ozonation, GAC filtration, ozonation followed by GAC filtration, and GAC filtration followed by ozonation) were evaluated and compared. Results showed that ozonation followed by GAC filtration was most effective in precursor removal and could decrease the level of these new phenolic DBPs by up to 97.3%. PMID- 30292955 TI - Acidification and recovery of phosphorus from digested and non-digested sludge. AB - Acidification was used to dissolve phosphorus from digested and non-digested sludge from five wastewater treatment plants in order to make phosphorus accessible for subsequent recovery. More phosphorus was dissolved from digested sludge (up to 80%), with respect to non-digested sludge (~25%) and the highest release was observed at pH 2. The acid consumption for digested sludge was higher than for non-digested sludge due to the presence of the bicarbonate buffer system, thus CO2 stripping increased the acid consumption. In all the experiments, the sludge was exposed to acid for 1 h. For the five tested sludge types, 60-100 mmol o-P was released per added mol H2SO4. It was mainly iron and calcium compounds that accounts for the phosphorus release at low pH. The release of heavy metals was in general low (<30%) for all the wastewater treatment plant, as Zn, Cd and Ni showed the most critical release after acidification of non digested sludge. PMID- 30292956 TI - Determination of radiocesium depth profile by unfolding method with imaging plate. AB - Radiocesium depth profiles in Fukushima soil cores were derived with an unfolding method by using an imaging plate with a response matrix for 134Cs, 137Cs, and 40K radionuclides calculated by a PHITS simulation. The unfolded depth profiles were validated by comparison with profiles measured with a Ge detector. The unfolded depth profiles agreed well with those measured by the Ge detector. The depth profiles obtained were obtained with a 1 mm depth bin width and are useful for estimating the migration of radiocesium in soil. PMID- 30292957 TI - Simulating the radial dose distribution for charged particles in water medium by a semi-empirical model: An analytical approach. AB - A computational semi-empirical model based on electronic radiation damage to medium has been presented to simulate the radial dose distribution. An analytical approach was used to calculate the deposited energy in water per unit mass within a cylindrical shell of unit length around the ion path at a radial distance between r and r + dr, the so-called radial dose distribution, RDD. Detail steps were given and the final radial dose integration over the electron range between Rmin and Rmax was solved numerically using the Mid-Point Method. A validation for the present model was presented by integrating the RDD over all possible radial distances, r to yield the tabulated LET of the ion. The validation was presented for a range of proton ions of different energies. The RDD for heavy charged particles of proton, alpha, Carbon and Oxygen ions of different energies in liquid water were obtained. Good agreement between the present model and experimental, theoretical, and Monte Carlo (Geant4-DNA) data were obtained for all ions under investigations. PMID- 30292958 TI - In-vivo assessment of osseous versus non-osseous transmission pathways of vibratory stimuli applied to the bone and the dura in humans. AB - BACKGROUND: Bone conduction (BC) is an alternative to air conduction (AC) for stimulation of the inner ear. Stimulation for BC can occur directly on the skull bone, on the skin covering the skull bone, or on soft tissue (i.e., eye, dura). All of these stimuli can elicit otoacoustic emissions (OAE). This study aims to compare OAEs generated by different combinations of stimuli in live humans, including direct stimulation of the intracranial contents via the dura, measured intraoperatively. METHODS: Measurements were performed in five normal-hearing ears of subjects undergoing a neurosurgical intervention with craniotomy in general anesthesia. Distortion product OAEs (DPOAEs) were measured for f2 at 0.7, 1, 2, 3, 4, and 6 kHz with a constant ratio of the primary frequencies (f2/f1) of 1.22. Sound pressure L1 was held constant at 65 dB SPL, while L2 was decreased in 10 dB steps from 70 to 30 dB SPL. A DPOAE was considered significant when its level was >=6 dB above the noise floor. Emissions were generated sequentially with different modes of stimulation: 1) pre-operatively in the awake subject by two air-conducted tones (AC-AC); 2) within the same session preoperatively by one air- and one bone-conducted tone on the skin-covered temporal bone as in audiometry (AC-BC); 3) intra-operatively by one air-conducted tone and one bone vibrator tone applied directly on the dura (AC-DC). A modified bone vibrator (Bonebridge; MED-EL, Innsbruck, Austria) was used for BC stimulation on the dura or skin-covered mastoid. Its equivalent perceived SPL was calibrated preoperatively for each individual by psychoacoustically comparing the level of a BC tone presented to the temporal region to an AC tone at the same frequency. Simultaneously with the DPOAEs, vibrations at the teeth were measured with an accelerometer attached using a custom-made holder. RESULTS: It was possible to record DPOAEs for all three stimulation modes. For AC-DC, DPOAEs were not detected above the noise floor below 2 kHz but were detectable at the higher frequencies. The best response was measured at or above 2 kHz with L2 = 60 dB SPL. The acceleration measured at the teeth for stimulation on the dura was lower than that for stimulation on the bone, especially below 3 kHz. CONCLUSION: We demonstrate a proof-of-concept comparison of DPOAEs and teeth acceleration levels elicited by a bone vibrator placed either against the skin-covered temporal bone, as in audiometry, or directly against the dura mater in patients undergoing a craniotomy. It was demonstrated that DPOAEs could be elicited via non-osseous pathways within the skull contents and that the required measurements could be performed intra-operatively. PMID- 30292959 TI - Cortical correlates of speech intelligibility measured using functional near infrared spectroscopy (fNIRS). AB - Functional neuroimaging has identified that the temporal, frontal and parietal cortex support core aspects of speech processing. An objective measure of speech intelligibility based on cortical activation in these brain regions would be extremely useful to speech communication and hearing device applications. In the current study, we used noise-vocoded speech to examine cortical correlates of speech intelligibility in normally-hearing listeners using functional near infrared spectroscopy (fNIRS), a non-invasive, neuroimaging technique that is fully-compatible with hearing devices, including cochlear implants. In twenty three normally-hearing adults we measured (1) activation in superior temporal, inferior frontal and inferior parietal cortex bilaterally and (2) behavioural speech intelligibility. Listeners heard noise-vocoded sentences targeting five equally spaced levels of intelligibility between 0 and 100% correct. Activation in superior temporal regions increased linearly with intelligibility. This relationship appears to have been driven in part by changing acoustic properties across stimulation conditions, rather than solely by intelligibility per se. Superior temporal activation was also predictive of individual differences in intelligibility in a challenging listening condition. Beyond superior temporal cortex, we identified regions in which activation varied non-linearly with intelligibility. For example, in left inferior frontal cortex, activation peaked in response to heavily degraded, yet still somewhat intelligible, speech. Activation in this region was linearly related to response time on a simultaneous behavioural task, suggesting it may contribute to decision making. Our results indicate that fNIRS has the potential to provide an objective measure of speech intelligibility in normally-hearing listeners. Should these results be found to apply similarly in the case of individuals listening through a cochlear implant, fNIRS would demonstrate potential for a clinically useful measure not only of speech intelligibility, but also of listening effort. PMID- 30292960 TI - Role of nesfatin-1 in anxiety, depression and the response to stress. AB - Nesfatin-1 has been discovered a decade ago and since then drawn a lot of attention. The initially proposed anorexigenic effect was followed by the description of several other involvements such as a role in gastrointestinal motility, glucose homeostasis, cardiovascular functions and thermoregulation giving rise to a pleiotropic action of this peptide. The recent years witnessed mounting evidence on the involvement of nesfatin-1 in emotional processes as well. The present review will describe the peptide's relations to anxiety, depressiveness and stress in animal models and humans and also discuss existing gaps in knowledge in order to stimulate further research. PMID- 30292961 TI - Stability of diurnal cortisol measures across days, weeks, and years across middle childhood and early adolescence: Exploring the role of age, pubertal development, and sex. AB - Effective regulation of the hypothalamic-pituitary-adrenal axis (HPA-axis) has been linked to numerous health outcomes. Within-person variation in diurnal measures of HPA-axis regulation assessed over days, months, and years can range between 50-73% of total variation. In this study of 59 youth (ages 8-13), we quantified the stability of the cortisol awakening response (CAR), the diurnal slope, and tonic cortisol concentrations at waking and bedtime across 8 days (2 sets of 4 consecutive days separated by 3 weeks), 3 weeks, and 3 years. We then compared the stability of these indices across three key developmental factors: age, pubertal status, and sex. Youth provided 4 saliva samples per day (waking, 30 min post-waking, before dinner, and before bedtime) for 4 consecutive days during the 3rd week of an ongoing 8-week daily diary study. Youth repeated this same sampling procedure 3 weeks and 3 years later. Using multi-level modeling, we computed the amount of variance in diurnal HPA-axis regulation that was accounted for by nesting an individual's diurnal cortisol indices within days, weeks, or years. Across days, diurnal slope was the most stable index, whereas waking cortisol and CAR were the least stable. All indices except bedtime cortisol were similarly stable when measured across weeks, and all indices were uniformly stable when measured across 3 years. Boys, younger participants, and youth earlier in their pubertal development at study enrollment exhibited greater HPA axis stability overall compared with females and older, more physically mature participants. We conclude that important within- and between-subjects questions can be answered about health and human development by studying HPA-axis regulation, and selection of the index of interest should be determined in part by its psychometric characteristics. To this end, we propose a decision tree to guide study design for research in pediatric samples by longitudinal timeframe and sample characteristics. PMID- 30292962 TI - To trust, or not to trust? Individual differences in physiological reactivity predict trust under acute stress. AB - The stress response represents an evolutionarily ancient array of biological responses to challenge or threat that facilitate survival by promoting adaptive behaviors. 'Adaptive' in the evolutionary sense, however, does not easily translate to explain stress' effect on human decisions. Much research demonstrates that acute stress alters decision-making, but outcomes are obscured by a range of methodological factors. Further, less is known about how stress affects decision-making in social contexts in which people so often act. This is of great importance in today's increasingly complex social environment, replete with potential stressors, where cooperation and trust are critical. Here the aim was to explore acute stress' effect on prosocial decision-making, while also controlling for methodological factors that may contribute to varied research outcomes. Ninety-six participants were exposed between-subjects to acute stressors with or without a significant social evaluative component, or a control procedure, after which they performed a variant of the Trust Game (a social decision-making task requiring cooperation and trust with a 'partner'). Task performance occurred at different times with respect to exposure to examine the roles of temporally distinct biological stress pathways. Overall acute stress was associated with reduced trust, but a more complex pattern emerged when accounting for individual differences in physiological stress responses via multivariate analysis. In keeping with the complexity of stress itself, acute stress may enhance or reduce propensity to trust based on an individual's unique pattern of physiological reactivity. PMID- 30292963 TI - Characterization of dog serum virome from Northeastern Brazil. AB - Domestic dogs share habitats with human, a fact that makes them a potential source of zoonotic viruses. Moreover, knowledge regarding possible bloodborne pathogens is important due to the increasing application of blood transfusion in dogs. In the present study, we evaluated the serum virome of 520 dogs using throughput sequencing (HTS). The serum samples were pooled and sequenced using an Illumina MiSeq platform. Our unbiased method identified prevalent canine pathogens as canine protoparvovirus 1 (canine parvovirus 2), undersearched agents as canine bocaparvovirus 1 (minute virus of canines) and canine circovirus, circular viruses closely related to viruses recently found in human samples, and new parvovirus and anelloviruses. The dog virome described in the present work furthers the knowledge concerning the viral population in domestic animals. The present data includes information regarding viral agents that are potentially transmitted through blood transfusion among dogs. PMID- 30292964 TI - Posttubercular syringomyelia in HIV-infected patients: A report of 10 cases and literature review. AB - OBJECTIVES: To describe the clinical presentation, spinal magnetic resonance imaging (MRI) findings and outcome of HIV-infected patients with tuberculosis (TB)-associated syringomyelia and to compare these findings between all HIV infected and -uninfected cases published in the literature. METHODS: A retrospective observational study conducted over a 12.5-year period at a public sector referral hospital in South Africa. HIV-infected adults with neurological TB in whom MRI confirmed a syrinx were included. We searched PubMed to identify all published syringomyelia cases. RESULTS: Ten patients were enrolled. Syringomyelia complicated neurological TB within four years of initial diagnosis in all patients (median: 21 months, range: 0-39) after initial diagnosis. Six patients were treated conservatively (TB treatment = 5, no treatment = 1); four improved, but only one was ambulant during follow-up. Four patients underwent syringoperitoneal shunting; three improved and one died three months later. Our literature review identified 50 additional cases (HIV-infected = 2, HIV uninfected = 9, HIV status not documented = 39 [presumed HIV-uninfected]). Clinical and imaging findings and outcomes were similar between HIV-infected and uninfected cases, except for time of presentation following neurological TB diagnosis, which was delayed (>4 years) in 46% of HIV-uninfected cases, compared to 8% of HIV-infected cases. Conclusions Syringomyelia is a disabling complication of neurological TB that usually presents early after neurological TB diagnosis in HIV coinfected patients. PMID- 30292965 TI - Mitochondrial therapeutic interventions in Alzheimer's disease. AB - Alzheimer's Disease (AD) is one of the most common age-related neurodegenerative diseases in the developed world. Treatment of AD is particularly challenging as the drug must overcome the blood brain barrier (BBB) before it can reach its target. Mitochondria are recognized as one of the most important targets for neurological drugs as the organelle is known to play a critical role in diverse cellular processes such as energy production and apoptosis regulation. Mitochondrial targeting was originally developed to study mitochondrial dysfunction and the organelles interaction with other sub-cellular organelles. The purpose of this review is to provide an overview of mitochondrial dysfunction and its role in late onset AD pathology. We then highlight recent antioxidant and enzymatic treatments used to alleviate mitochondrial dysfunction. Finally, we describe current applications of targeted mitochondrial delivery in the treatment of AD. PMID- 30292967 TI - Brain modelling in the framework of anisotropic hyperelasticity with time fractional damage evolution governed by the Caputo-Almeida fractional derivative. AB - In this paper the human brain tissue constitutive model for monotonic loading is developed. The model in this work is based on the anisotropic hyperelasticity assumption (the transversely isotropic case) together with modelling of the evolving load-carrying capacity (scalar damage) whose change is governed by the Caputo-Almeida fractional derivative. This allows the brain constitutive law to include the memory during progressive damage, due to the characteristic time length scale which is an inherent attribute of the fractional operator. Furthermore, the rate dependence of the overall brain tissue model is included as well. The theoretical model is finally calibrated and validated with a set of experimental data.

PMID- 30292968 TI - One-year mortality of patients admitted to the intensive care unit after in hospital cardiac arrest: a retrospective study. AB - PURPOSE: Little is known about long-term survival after In-Hospital Cardiac Arrest (IHCA). The purpose of this study is to report the one-year survival of patients after IHCA and to identify predicting factors. METHODS: Single-center retrospective study of all adult in-hospital CPR attempts conducted between 2003 and 2014 in a tertiary teaching hospital. Demographic and clinical variables of patients were obtained at 24 h pre-arrest, during CPR and post-CPR. All patients were tracked one year after discharge from hospital. RESULTS: CPR was performed for IHCA on 417 patients. Return of spontaneous circulation (ROSC) was achieved in 283 (68%) patients, 234 were admitted to ICU. Overall, 95 (23%) patients survived one year after discharge, The survival rate of patients who were admitted to ICU after IHCA was 38% (89/234) at hospital discharge and 26% (61/234) at one year. Univariate analysis showed numerous variables are associated with one-year survival, for example comorbidity index and time to ROSC. DISCUSSION: One-year survival of patients admitted to the ICU after IHCA was 26%. Severity of disease pre-arrest and at ICU-admission could prove useful in prognostication. No multivariate model could be constructed and large prospective studies are needed to elicit the role of pre-arrest factors on survival. PMID- 30292969 TI - Diabetes progression and alterations in gut bacterial translocation: prevention by diet supplementation with human milk in NOD mice. AB - Impaired intestinal barrier function occurs before type 1 diabetes (T1D) onset with a possible contribution of microbial translocation. Breastfeeding is associated with enhanced mucosal intestinal integrity and T1D protection. Our aim was to study the potential of human milk (HM) to prevent diabetes onset and modulate the translocation of gut bacteria susceptible to breastfeeding or associated to diabetes onset. We show that HM intake can prevent T1D in nonobese diabetic mice independently of bifidobacteria colonization. Prior to diabetes onset, HM mice harbored splenic bacterial counts and plasma lipopolysaccharides level similar to control mice but exhibited a reduced expansion of Anaerotruncus sp. in pancreas and Lactobacillus johnsonii and Barnesiella in Peyer's patches (PP). Surprisingly, pancreas and PP bacterial expansion did not correlate with their own gut localization but with ileal Escherichia coli and cecal HM susceptible bacteria (the promoted L. murinus and Bacteroides vulgatus, and the repressed B. fragilis and E. coli), respectively. Besides, higher colonic B. vulgatus counts induced by HM intake were associated with low islet infiltration and pancreatic E. coli expansion. On another hand, splenic dendritic cells (DCs) were identified as negative covariate of PP Barnesiella, suggesting a possible HM contribution to preserving splenic DCs through the reduction of Barnesiella translocation. Fecal B. vulgatus also negatively correlated with PP Barnesiella expansion, indicating that the mouse coprophagic behavior likely added to HM effect. Our findings provide evidence that HM has a multilevel impact and cooperates with some gut bacteria for controlling bacterial translocation at the earliest stage of insulitis. PMID- 30292970 TI - Pb (II) bioavailability to algae (Chlorella pyrenoidosa) in relation to its complexation with humic acids of different molecular weight. AB - Humic acid (HA) has a major influence on the environmental fate of metal ions due to its heterogeneity in chemical compositions, structure and functional groups. In this study, we investigated the effect of humic acid (HA) with different molecular weight (Mw) on the bioavailability of Pb for a representative algae Chlorella pyrenoidosa. The results showed that HA with larger Mw had stronger inhibitory effects on the bioavailability of Pb to algae, and the biosorption capacity of Pb decreased with increasing Mw, which is in accordance with the variations of complexation capacities of Pb for HA fraction. In addition, we found that HA with Mw lower than 10 kDa could increase the biosorption capacity of Pb. The considerable differences among the Mw fractions on Pb biosorption were mainly attributed to their properties and corresponding complexation capacities. Phenolic groups were responsible for the variations of binding capacities among different Mw fractions, and it could also better explain the bioaccumulation of Pb to the membranes of algae. By using NICA-Donnan model, we found that over 60% of Pb ions were bound by HAs through specific binding, and the formation of Pb HAs complex were non-bioavailable to algae, which was proved by the considerably decreasing percentage of internalized Pb. This study provided further insight into the bioavailability of Pb to algae as influenced by the complexation of HA with metal ion such as Pb. PMID- 30292971 TI - Exogenous foliar application of fulvic acid alleviate cadmium toxicity in lettuce (Lactuca sativa L.). AB - It was reported that fulvic acid (FA) has a positive effect on enhancing plant tolerance to various environmental stresses, including salinity stress and drought stress and so on. However, there is little study regarding the effects of FA on plants in response to heavy metal stress. Hence, the objective of this study was to investigate the potential effects of fulvic acid (FA) on cadmium (Cd) toxicity alleviation in lettuce seedlings. Our results showed that application of 0.5 g/L FA significantly mitigate Cd-induced toxic symptoms in lettuce seedlings. Cd stress triggered plant growth inhibition, photosynthetic pigment reduction, destruction of the photosynthesis apparatus, reactive oxygen species (ROS) accumulation, and nutrient elemental imbalance. We observed that FA promoted the growth in lettuce under Cd stress, mainly reflected in those alterations that the increase of biomass, chlorophyll content and photosynthesis capacity and reduction of the Cd content and lipid peroxidation in plant tissue. Foliar spraying of FA significantly alleviated these detrimental symptoms and facilitated nutrient element translocation from root to shoot, particularly the absorption of elements involved in photosynthesis, including iron (Fe), zinc (Zn), and manganese (Mn). In summary, foliar application of FA conferred Cd toxicity tolerance to lettuce by increasing ROS-scavenging capacity, inhibiting Cd uptake and the transport of elemental nutrients to shoots, which in turn protected the photosynthetic apparatus and promoted plant growth. PMID- 30292972 TI - Toxicity assay of lanthanum and cerium in solutions and soil. AB - Lanthanum (La) and cerium (Ce) are one of the most abundant rare earth elements (REEs). In spite of quite extensive studying of the effects of these lanthanides on biota, some contradictions remain in the results. Also little is known about the effect of lanthanum and cerium on plant cells and their mitotic cycle, especially in soils. In this study, the effects of La and Ce in solutions and soil samples on root growth, mitotic index (MI) and frequency of aberrant cells (FAC) were assayed using one of the most convenient objects for testing of cytotoxicity - onion Allium cepa L. Bulbs were germinated on media containing La and Ce in concentrations 0-200 mg/l and 0-50 mg/l respectively for solutions and 0-200 mg/kg for soil samples. After 5 days of germination in solutions, a significant decrease in root elongation and MI in apical meristem cells are shown. We have also observed an increase in the number of cells with aberrations at 50 mg/l La and Ce concentration. The number of observed stickiness and disturbed metaphase has increased significantly. Soil samples turned out to be less toxic compared to the solutions probably due to the decreased availability of REEs. In spite of this, significant cytotoxicity of soil samples containing the highest concentration of La and Ce (200 mg/kg) is observed. The latter may indicate the importance of considering the cytotoxicity of soils containing high lanthanides concentrations - in extraction and production areas and actively fertilized fields.

AB - Perfluorooctanoic acid (PFOA) is a perfluorinated compound that is widely distributed, is persistent in the environment, and has a low-level chronic exposure effect on human health. The aim of this study was to investigate the peroxisome proliferator activated receptors gamma (PPARgamma) and the sterol regulatory element-binding protein 2 (SREBP2) signaling pathways in regulating the lipid damage response to PFOA in the livers of amphibians. Male and female frogs (Rana nigromaculata) were exposed to 0, 0.01, 0.1, 0.5 and 1 mg/L PFOA. After treatment, we evaluated the pathological changes in the liver by Oil Red O, staining and examined the total cholesterol (T-CHO) and triglyceride (TG) contents. The mRNA expression levels of PPARgamma, Fatty acid synthase (FAS), Acetyl-CoA carboxylase (ACC), Glycerol-3-phosphate acyltransferase (GPAT), SREBP2 and 3-hydroxy-3-methylglutaryl CoA (HMG-CoA) were measured by quantitative real time polymerase chain reaction (qRT-PCR). The administration of PFOA caused marked lipid accumulation damage in the amphibian livers. The T-CHO contents were elevated significantly after PFOA treatment; these results show a dose-dependent manner in both sexes. The TG content showed a significant increase in male livers, while it was elevated significantly in female livers. The RT-PCR results showed that the mRNA expression levels of PPARgamma, ACC, FAS, GPAT, SREBP2 and HMG-CoA were significantly dose-dependently increased in the PFOA-treated groups compared with those of the control group. Our results demonstrated that PFOA induced lipid accumulation also affected the expression levels of genes FAS, ACC, GPAT and HMG-CoA in the PPARgamma and SREBP2 signaling pathways in the liver. These finding will provide a scientific theoretical basis for the protection of Rana nigromaculata against PFOA effects. PMID- 30292974 TI - Response of Pseudomonas fluorescens to dimethyl phthalate. AB - Dimethyl phthalate (DMP) is a ubiquitous pollutant that is very harmful to organisms due to its mutagenicity, teratogenicity and carcinogenicity. Pseudomonas fluorescens (P. fluorescens) is one of the most important bacteria in the environment. In this study, the response of P. fluorescens to DMP was investigated. It was found that DMP greatly inhibited the growth and glucose utilization of P. fluorescens when the concentration of DMP was ranged from 20 to 40 mg/l. The surface hydrophobicity and membrane permeability of P. fluorescens were also increased by DMP. DMP could lead to the deformations of cell membrane and the mis-opening of membrane channels. RNA-Seq and RT-qPCR results showed that the expression of some genes in P. fluorescens were altered, including the genes involved in energy metabolism, ATP-binding cassette (ABC) transporting and two component systems. Additionally, the productions of lactic acid and pyruvic acid were reduced and the activity of hexokinase was inhibited in P. fluorescens by DMP. Clearly, the results suggested that DMP contamination could alter the biological function of P. fluorescens in the environment. PMID- 30292975 TI - Bacterial community variations in paddy soils induced by application of veterinary antibiotics in plant-soil systems. AB - Soil bacterial communities have complex regulatory networks, which are mainly associated with soil fertility and ecological functions, and are likely to be disturbed due to antibiotics applications. The impact of antibiotics, particularly in mixtures form, on bacterial communities in different paddy soils is poorly understood. Using pyrosequencing techniques of 16 S rRNA genes, this study investigated the synergistic effects of veterinary antibiotics (sulfadiazine, sulfamethoxazole, trimethoprim, florfenicol, and clarithromycin) on bacterial communities in a soil-bacteria-plant system. Rice was grown under controlled greenhouse conditions where unplanted and planted treatments were doped with 200 ug kg-1 of combined antibiotics over a period of 3 months. Bacterial richness remained unaltered, while a significant decline was observed in bacterial diversity due to antibiotics in the four paddy soils. Bacteroidetes and Acidobacteria were increased, while Actinobacteria and Firmicutes decreased under antibiotics exposure. Despite antibiotics perturbation, compositional variations were mainly attributed to the different paddy soils which harbor distinct bacterial communities. Haliangium and Gaiella were among the sensitive genera that were negatively correlated to antibiotics perturbation. Additionally, electrical conductivity, total organic carbon, and total nitrogen of soil solution were the key physiochemical indices which significantly influenced the structure of bacterial communities in the paddy soils. These findings expanded our knowledge of effects from synergistic antibiotics application and variations in bacterial communities among different paddy soils. PMID- 30292976 TI - Reliable model established depending on soil properties to assess arsenic uptake by Brassica chinensis. AB - Generally, prediction of arsenic (As) bioavailability, mobility and its transfer from soil to plant is very important with respect to management of environment and food safety. In this study, pakchoi (Brassica chinensis) was sown in a greenhouse to evaluate the As transfer characteristics from different soils to plant system, and to investigate the possible prediction equations and key factors involved in As bioavailability. The results showed that As uptake of plant and soil As concentration was significantly and positively correlated (R2 = 0.778; P < 0.01). A log-transformed data provided a better correlation (R2 = 0.901; P < 0.01). Results obtained from stepwise multiple linear regression (SMLR) showed that soil pH and total As were important variables involved in the contribution of As transfer to plant. The As accumulation in plant exhibited a positive correlation with soil As content and pH. Various prediction equations were obtained from different As sources, whereas the most favourable equation was screened by root mean square error (RMSE) between the measured and predicted Log [plant As] content. The prediction model (Log [plant As] =1.34 Log [soil As] +0.18pH-1.25) showed the greatest accuracy of R2 = 0.978 and RMSE = 0.11, by combining the data of three As treatments (45 observed data points). These current findings are quite useful and could be used for predicting the As transfer from soil to plant system. PMID- 30292977 TI - Neuropsychological assessment of patients undergoing surgery due to low-grade glioma involving the supplementary motor area. AB - OBJECTIVE: The aim of the study was to establish the usefulness of various neuropsychological tests in patients undergoing surgery due to low-grade glioma (LGG) involving supplementary motor area (SMA). PATIENTS AND METHODS: 21 patients diagnosed with LGG involving the SMA underwent, before and after surgery, screening tests (Mini Mental State Examination - MMSE, Montreal Cognitive Assessment - MoCA and Frontal Assessment Battery - FAB), tests to assess language functions (Addenbrook's Cognitive Examination-III - ACE-III, phonetic fluency tests and semantic fluency tests), tests to assess memory functions (Rey's 15 word test - RAVLT and Diagnostic Test for Brain Damage by Hillers- DCS), tests to assess executive functions (Wisconsin Card Sorting Test - WCST, Ruff Figural Fluency Test - RFFT and Trail Making Test). RESULTS: Before surgery, in the screening tests the patients obtained below normal scores in the MoCA test only. After surgery, the scores of such tests were significantly worse than the scores before surgery, while the MMSE test scores continued to be within the normal range. In phonetic and semantic fluency tests, the patients obtained worse scores, both before and after surgery. The differences in the test scores between the two periods, i.e. before and after surgery, were statistically significant. Although the patients obtained worse scores both before and after surgery in the ACE III test, the differences in the test scores were not statistically significant. The scores obtained in all tests assessing the executive and memory functions before and after surgery were within the normal range. The scores in such tests (except the WCCT) dropped significantly after surgery. CONCLUSIONS: Patients diagnosed with LGG involving the SMA reveal the impairment of cognitive functions, in particular language functions. After surgery, a significant impairment of all elementary cognitive functions, such as attention, memory, language and executive functions and complex cognitive functions, occurs. The most sensitive tests to detect cognitive disorders, executive dysfunctions and speech disturbances in patients undergoing surgery due to glioma include the MoCA, FAB and Phonetic and Semantic Fluency Tests. PMID- 30292978 TI - Diffuse low grade glioma after the 2016 WHO update, seizure characteristics, imaging correlates and outcomes. AB - OBJECTIVES: The majority of patients with supratentorial diffuse grade II glioma present with seizures, which adversely affect quality of life. The exact mechanism of epileptogenesis is unknown and the influence of tumour characteristics, radiological and histological, are not well studied, particularly following the introduction of molecular genetics in the 2016 WHO reclassification of gliomas. We sought to define predictors of seizure development and outcome in low grade glioma. PATIENTS AND METHODS: A retrospective review of patients who underwent resection of a supratentorial grade II glioma in a single institution. All patients underwent surgery at initial presentation with the aim of maximal safe resection. Presenting symptoms and radiological variables were recorded, including eloquent location, cortical involvement, tumour margins and tumour volume. Extent of resection (EOR), surgery type (awake vs asleep) and seizure outcome were analysed. Using molecular genetics data the original histology was reclassified according to the 2016 WHO update. RESULTS: 63 patients were included, 45 (71%) presented with seizures. 36 (57%) had oligodendroglioma and 27 astrocytoma. IDH-1 mutation was present in 53 (84%). 18 (29%) had tumour in an eloquent location. 33 (73%) were Engel class I following surgery at median follow up of 43 months. 6 patients were Engel II, 6 class III. Complete and near total resection were associated with improved Engel class compared to subtotal resection. No factors such as age, tumour location, tumour margins or tumour molecular genetics (including IDH-1 mutation) predicted better seizure outcome. Updated histological subtype did not predict the presence of seizures at initial diagnosis, only tumour heterogeneousity on initial MRI (p = 0.043). More patients who underwent awake craniotomy with intraoperative mapping were Engel class 1 post-operatively than those operated under general anaesthetic (84% vs 65%). Tumour volume at presentation did not correlate with seizure outcome but impacts on the EOR. CONCLUSION: Seizure outcome is directly related to EOR in low grade glioma, which can be predicted by the initial tumour volume. Tumour histological subtype, including updated molecular genetic classification did not predict seizure development or outcome in this series. The use of awake craniotomy results in greater EOR and improved Engel Class following surgery. PMID- 30292979 TI - Prognostic and predictive biomarkers for somatostatin analogs, peptide receptor radionuclide therapy and serotonin pathway targets in neuroendocrine tumours. AB - Neuroendocrine tumours (NETs) are a heterogeneous group of neoplasms regarding their molecular biology, clinical behaviour, prognosis and response to therapy. Several attempts to establish robust predictive biomarkers have failed. Neither tissue markers nor blood borne ones have proven to be successful yet. Circulating tumour cells (CTCs) as "liquid biopsies" could provide prognostic information at the time a therapeutic decision needs to be made and could be an attractive tool for tumour monitoring throughout the treatment period. However, "liquid biopsies" are far from becoming the standard biomarker in NETs. Promising results have been presented over the last few years using a novel biomarker candidate, a multianalyte algorithm analysis PCR-based test (NETest). New technologies will open the field to different ways of approaching the biomarker conundrum in NETs. However, the complications derived from being a heterogeneous group of malignancies will remain with us forever. In summary, there is an unmet need to incorporate new biomarker candidates into clinical research trials to obtain a robust prospective validation under the most demanding scenario. PMID- 30292980 TI - Transcriptomic view of survival during early seedling growth of the extremophyte Haloxylon ammodendron. AB - Seedling establishment in an extreme environment requires an integrated genomic and physiological response to survive multiple abiotic stresses. The extremophyte, Haloxylon ammodendron is a pioneer species capable of colonizing temperate desert sand dunes. We investigated the induced and basal transcriptomes in H. ammodendron under water-deficit stress during early seedling establishment. We find that not only drought-responsive genes, but multiple genes in pathways associated with salt, osmotic, cold, UV, and high-light stresses were induced, suggesting an altered regulatory stress response system. Additionally, H. ammodendron exhibited enhanced biotic stress tolerance by down-regulation of genes that were generally up-regulated during pathogen entry in susceptible plants. By comparing the H. ammodendron basal transcriptome to six closely related transcriptomes in Amaranthaceae, we detected enriched basal level transcripts in H. ammodendron that shows preadaptation to abiotic stress and pathogens. We found transcripts that were generally maintained at low levels and some induced only under abiotic stress in the stress-sensitive model, Arabidopsis thaliana to be highly expressed under basal conditions in the Amaranthaceae transcriptomes including H. ammodendron. H. ammodendron shows coordinated expression of genes that regulate stress tolerance and seedling development resource allocation to support survival against multiple stresses in a sand dune dominated temperate desert environment. PMID- 30292981 TI - Trans-aconitic acid inhibits the growth and photosynthesis of Glycine max. AB - Grasses producing trans-aconitic acid, a geometric isomer of cis-aconitic acid, are often used in Glycine max rotation systems. However, the effects of trans aconitic acid on Glycine max are unknown. We conducted a hydroponic experiment to evaluate the effects of 2.5-10 mM trans-aconitic acid on Glycine max growth and photosynthesis. The results revealed that the enhanced H2O2 production in the roots increased the membrane permeability and reduced the water uptake. These effects culminated with a reduced stomatal conductance (gs), which seems to be the main cause for a decreased photosynthetic rate (A). Due to low gs, the limited CO2 assimilation may have overexcited the photosystems, as indicated by the high production of H2O2 in leaves. After 96 h of incubation, and due to H2O2 induced damage to photosystems, a probable non-stomatal limitation for photosynthesis contributed to reducing A. This is corroborated by the significant decrease in the quantum yield of electron flow through photosystem II in vivo (PhiPSII) and the chlorophyll content. Taken together, the damage to the root system and photosynthetic apparatus caused by trans-aconitic acid significantly reduced the Glycine max plant growth. PMID- 30292982 TI - Recurrent water deficit causes alterations in the profile of redox proteins in citrus plants. AB - Plant acclimation to recurrent stress involves profound alterations in multiple genetic, metabolic and physiological processes. Stressful conditions usually implicate imbalance in reactive oxygen species (ROS) production and removal rates, which may lead to oxidative stress. However, the primary cellular targets of oxidative stress and their relevance in plant acclimation to abiotic stresses remains poorly characterized. By comparing redox proteomic and sugar profiles in citrus Valencia (VO) scions grafted onto two rootstocks with different soil water extraction capacities - Rangpur Lime (RL) and Sunki Maravilha (SM) - here we demonstrate that both ROS-mediated post-translational protein modification and changes in sugar composition are associated with acclimation to recurrent drought in citrus. The redox proteomic analysis of the distinct scion/rootstock combinations exposed to one (WD1), two (WD2) or three (WD3) water deficit episodes revealed a total of 32 and 55 redox protein spots present in VO/RL and VO/SM plants, respectively. Mass spectrometry analysis of these protein spots revealed essential targets of ROS-mediated posttranslational protein modification in citrus plants challenged by recurrent drought. The oxidation of cysteine thiol groups into glyceraldehyde 3-phosphate dehydrogenase (GAPDH) was shown to increase in WD3 samples of the VO/RL combination, whereas the opposite was observed for the VO/SM combination. Similarly, recurrent drought promoted the oxidation of catalase thiol groups in VO/SM, but not in VO/RL. Carbohydrate profiling revealed that glucose, fructose and galactose may also contribute to the phenotypic differences observed between the citrus genotypes exposed to drought. These findings reveal for the first time that recurrent drought differentially affects the profile of redox proteomics of citrus, suggesting that this alteration may be part of the stress memory in perennial plants. PMID- 30292984 TI - Metabolomic study of serum, urine and bronchoalveolar lavage fluid based on gas chromatography mass spectrometry to delve into the pathology of lung cancer. AB - This study explores for the first time the combination of serum, urine and bronchoalveolar lavage fluid (BALF) to deep insight into the pathology of lung cancer (LC) using a metabolomic platform based on gas chromatography mass spectrometry (GCMS). The study includes LC patients, healthy control group (HC) and a group of patients with noncancerous lung diseases (NCC) used as a control group respect to BALF because of the invasive nature this fluid collection. The metabolomic platform was applied to serum, urine and BALF samples in order to compare the metabolomic profiles of these biological fluids and establish metabolic similarities and differences between them. The application of PLS-DA presented a clear classification of groups for all types of samples, indicating the existence of altered metabolites in LC. Twenty six and thirty one perturbed metabolites in the LC were annotated in the comparison of serum and urine samples. On the other hand, sixteen metabolites were altered in BALF of LC patients compared to NCC. The pathway analysis indicated that several amino acid metabolic routes were the most affected in LC. Finally, ROC curves were applied to the dataset and metabolites with an AUC value higher than 0.75 were considered as relevant in the progression of LC. PMID- 30292983 TI - Isotope dilution LC-ESI-MS/MS and low resolution selected reaction monitoring as a tool for the accurate quantification of urinary testosterone. AB - A new analytical method for the quantification of testosterone in human urine samples by isotope dilution mass spectrometry is proposed. A standard solution of 13C2-testosterone is added to the samples at the beginning of the sample preparation procedure and then the measurements are carried out by UHPLC-ESI MS/MS. In the proposed method, the resolution of the first quadrupole of the tandem MS instrument is reduced to transmit the whole precursor ion cluster to the collision cell and measure the isotopic distribution of the in-cell product ions with a small number of SRM transitions. The construction of a methodological calibration graph is avoided using a labelled analogue previously characterised in terms of concentration and isotopic enrichment in combination with multiple linear regression. In this way, the molar fractions of natural and labelled testosterone are calculated in each sample injection and the amount of endogenous testosterone computed from the known amount of labelled analogue. Recovery values between 97 and 107% and precisions between 0.4 and 3.7% (as %RSD) were obtained for testosterone concentrations in urine in the range of 1 to 8 ng g-1. The proposed low resolution SRM methodology was compared for the analysis of human urine samples with the traditional IDMS method based on a calibration graph and the IDMS method based on multiple linear regression combined with standard resolution SRM. A similar accuracy and precision was obtained by the three tested approaches. However, using the low resolution SRM method there was no need to resort to calibration graphs or to specific dedicated software to calculate isotopic distributions by tandem MS and a higher sensitivity was obtained. The proposed low resolution SRM method was successfully applied to the analysis of the certified freeze-dried human urine NMIA MX005. PMID- 30292985 TI - Two findings of gallstones in archaeological mummies from Colombia. AB - Results involving the analysis of gallstones found in two pre-Hispanic Colombian mummies are presented. By applying SEM, X-ray diffraction (XRD), sectioning, and CT-scan Hounsfield Units, we were able to identify these choleliths as mainly formed by cholesterol. The number of reports on gallstones in archaeological human remains from South America is very small, making these two cases an important addition to what little is known about ancient gallstone disease on the continent. PMID- 30292986 TI - "Aged" autopsy gallstones simulating dry bone context: A morphological, histological and SEM-EDS analysis. AB - OBJECTIVE: The aim of this paper is to provide information on the morphology and composition of gallstones based on clinical samples in order to assist paleopathologists and bioarchaeologists in recognizing their presence in archaeological contexts. MATERIALS AND METHODS: 270 gallstones were extracted and macerated from autopsies conducted at the Istituto di Medicina Legale in Milan (Italy) in order to simulate a dry bone recovered from archaeological contexts. Morphological, histological, and elemental variation was documented. RESULTS: Gallstones vary in size, shape, color and texture. The cross-sectional surface correlates with chemical composition and is a valuable tool for classification into subcategories of stones. Histological analysis can confirm the classification. Elemental analysis yielded a higher frequency of carbon, calcium and phosphorus. CONCLUSIONS: Although identification of gallstones in archaeological contexts can be challenging, familiarity with morphological, histological, and elemental variation can assist researchers in the field and laboratory. SIGNIFICANCE: Identifying gallstones in archaeological populations will assist researchers in estimating their frequency in the past and the environmental, cultural, and biological conditions leading to their presence. LIMITATIONS: Small sample size derived from a modern and limited autopsy population may minimize the types and degree of variation present in the past. Effects of climate, soil, and taphonomy were not evaluated. SUGGESTIONS FOR FURTHER RESEARCH: Examination of larger samples derived from diverse populations may reveal greater variation or more diagnostic aspects of stones. PMID- 30292987 TI - Preliminary evidence of an association between increased cortical inhibition and reduced suicidal ideation in adolescents treated for major depression. AB - BACKGROUND: Suicide is a leading cause of death among youth. Prior research using transcranial magnetic stimulation (TMS) has implicated deficits in GABAergic cortical inhibition in adolescent suicidal behavior, yet no studies have assessed whether cortical inhibition varies over time in conjunction with changes in suicidal ideation (SI). This study examined dynamic changes in long-interval intracortical inhibition (LICI), a TMS measure of GABAB-mediated inhibition, and their relationship with changes in SI in a small sample of adolescents undergoing pharmacologic treatment for depression. METHODS: Ten depressed adolescents (aged 13-17) underwent clinical assessment and TMS testing at baseline and again at follow-up. All were treated with antidepressant medication in the interim. SI was measured with the Columbia Suicide Severity Rating Scale (C-SSRS) Intensity of Ideation subscale. LICI was measured at interstimulus intervals of 100 and 150 ms. RESULTS: There was a significant partial correlation, controlling for change in depression severity, between DeltaLICI-100 and change in SI as measured by DeltaC-SSRS (rho = .746, df = 7, p = .021), which remained after also controlling for time to follow-up assessment (rho = .752, df = 6, p = .032). No significant correlation was observed between DeltaLICI-150 and change in SI. LIMITATIONS: Sample size; variable follow-up interval; inability to control for age, sex, and potential treatment effects. CONCLUSIONS: These data offer preliminary signal of an association between increases in GABAB-mediated cortical inhibition and reduction in SI over time in adolescents treated for depression. Further studies are warranted to explore the role of cortical inhibition in adolescent suicidal ideation and behavior. PMID- 30292988 TI - The effect of cancer on the labor supply of employed men over the age of 65. AB - This paper investigates the relationship between cancer diagnosis and the labor supply of employed men over the age of 65. While almost 60% of male cancers are diagnosed in men over the age of 65, no previous research has examined the effect that cancer has on this age group, which is surprising given the relevance of this group to public policy. With data from the Health and Retirement Study, I show that cancer has a significant negative effect on the labor supply of these workers. Using a combination of linear regression models and propensity score matching, I find that respondents who are diagnosed with cancer work 3 fewer hours per week than their non-cancer counterparts. They are also 10 percentage points more likely to stop working. This reduction seems to be driven by a deterioration in physical and mental health. PMID- 30292989 TI - Environmental monitoring and risk assessment of pesticide residues in surface waters of the Louros River (N.W. Greece). AB - Estuarine environments are being constantly stressed by new sources of pollution (e.g. pesticides) derived from activities of industry and intensive agriculture. The present study aims at quantify pesticides of three different categories (fungicides, herbicides and insecticides) in the Louros River (Epirus region, North-Western Greece). A monitoring study of 34 compounds was carried out in surface river waters from June 2011 until May 2012. Seven water sampling stations were established and 35 water samples were collected. A solid-phase extraction (SPE) method coupled with gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS), depending on the compound, was developed and validated. During the monitoring study 25 pesticides were detected (13 herbicides, 9 insecticides, 3 fungicides). The most commonly encountered pesticides were quizalofop-ethyl, trifluralin and pendimethaline. Tebufenpyrad was found in all sampling stations and seasons, with the highest concentrations of 0.330 MUg/L at Tsopeli Lagoon exceeding the rather low concentrations reported nationwide. Regarding the environmental risk due to the presence of target compounds in surface waters, this was estimated by calculating risk quotients (RQs) for different aquatic organisms (algae, zooplankton and fish). The results denoted a possible threat for the aquatic environment, rendering in this way the RQ method as a useful screening tool. In any case, further extensive study is needed for acetochlor, pirimiphos-methyl, endosulfan-a and azinphos-ethyl in order to better correlate their occurrence and potential toxic effects in aquatic life and humans. PMID- 30292990 TI - Ecological and socioeconomic effects of ecological restoration in China's Three Rivers Source Region. AB - The Three Rivers Source Region, in the central Qinghai-Tibet Plateau, has a sensitive and fragile ecological environment. Adverse changes in climate and human activities have degraded the grassland ecosystems. To mitigate or reverse the degradation, alleviate rural poverty, and stimulate economic development, ecological restoration projects have been implemented. In the present study, our goal was to assess the ecological and socioeconomic effects of these programs based on land-use change, grassland NPP, and household surveys. Household data were collected using structured questionnaires in 11 villages from three counties, with average elevation above 3773 m asl. We found that the grassland degradation had been mitigated, especially after the implementation of ecological restoration programs since 2005 in a regional nature reserve in Qinghai Province. Household income depends strongly on the region's natural resources, so the grassland ecosystems are still at risk of unsustainable use. A household that understood the effects of the ecological restoration programs and had received training to participate in the programs was more willing to participate in future programs. Our findings suggest that for successful restoration, it is essential to help residents of the study area thoroughly understand the ecological restoration programs and learn the restoration techniques before implementation of such programs. This is because the participation of the residents depended strongly on both their income and their satisfaction with the ecological restoration programs. PMID- 30292991 TI - Soil microbial community structure in the rhizosphere of Robinia pseudoacacia L. seedlings exposed to elevated air temperature and cadmium-contaminated soils for 4 years. AB - The co-occurrence of heavy metal contamination of soils and increasing air temperature can affect the microbial community in rhizosphere soils by altering the allocation of plant photosynthates to roots. Here, we investigated the community structure of bacteria, fungi, ammonia oxidizing bacteria (AOB) and ammonia oxidizing archaea (AOA) in the rhizosphere of Robinia pseudoacacia L. seedlings exposed to elevated air temperature (+1.99 degrees C) and cadmium (Cd) for 4 years. Elevated temperature increased the richness of bacterial and AOA communities by 15.1% to 43.8% and by 1.4% to 18.6%, respectively, and decreased fungal and AOB richness by 3.7% to 28.7% and by 2.1% to 30.6%, respectively, under Cd exposure. Elevated temperature combined with Cd exposure decreased fungal diversity by 1.5% to 14.0%. However, elevated temperature decreased the diversity of bacteria, AOB and AOA by 1.4%, 17.4% and 10.1%, respectively, under 1.0 mg Cd kg-1 dry soil and increased the diversity of these taxa by 1.5%, 15.3% and 9.2%, respectively, under 5.0 mg Cd kg-1 dry soil relative to Cd exposure alone. Elevated temperature led to increased abundance of genera such as Methylobacterium, Stenotrophomonas, and Archangium and decreased abundance of genera including Ramlibacter, Microascus and Nitrosospira under Cd exposure. Over all, 4 years of exposure to elevated temperature had a greater effect on the community structure of bacteria, fungi, AOB and AOA when combined with Cd pollution. PMID- 30292992 TI - Marine vegetation analysis for the determination of volatile methylsiloxanes in coastal areas. AB - Volatile methylsiloxanes (VMSs) are massively produced chemicals that comprise a wide range of industrial and household applications. The presence of cyclic and linear VMSs in several environmental matrices and ecosystems indicates persistence associated with a potential of (bio)accumulation and food web transfer with possible toxicological effects. Due to the high anthropogenic pressure in its vicinities particularly in summer, coastal areas in Southern European countries are potential hotspots for the presence of VMSs. The massive afflux of tourists and consequent increase of the use of personal care products (PCPs) with VMSs in their formulations highlight the importance of VMSs assessment in such areas. In this study, different species of marine vegetation (algae and seaweed) were collected in three different geographical areas, covering the Atlantic Ocean (North coast of Portugal), as well as the Mediterranean Sea (coasts of the Region of Murcia, Spain and of the city of Marseille, France). Samples were analysed for the determination of 4 cyclic (D3, D4, D5, D6) and 3 linear (L3, L4, L5) VMSs employing a QuEChERS extraction methodology, followed by gas chromatography/mass spectrometry (GC/MS) quantification. VMSs were detected in 92% of the 74 samples analysed, with the sum of the concentrations per sample ranging from below the limit of detection (LOD) to 458 +/- 26 ng.g-1dw (dry weight). A strong predominance of cyclic VMSs over linear ones was verified in almost all samples studied, with D5 and D6 found at higher concentrations. Seasonal variation was also assessed and despite higher levels of VMSs being identified mostly in summer months, clear seasonal trends were not perceived. It was also noted that generally the higher incidence of VMSs occurred in samples from urban and industrialized areas or in the vicinities of WWTPs, suggesting a direct input from these sources in the levels of siloxanes observed. PMID- 30292993 TI - Dynamic monitoring of aeolian desertification based on multiple indicators in Horqin Sandy Land, China. AB - Aeolian desertification has become one of the most serious environmental and socioeconomic problems facing the world today. Quantitative remote sensing technology is an important means to achieve the development trends of aeolian desertified land (ADL). To compensate for the shortcomings in the time scale of Landsat Thematic Mapper and other high-spatial-resolution remote sensing data, this study introduces Moderate Resolution Imaging Spectroradiometer time series data and products to invert the monitoring indicators of ADL. The QUEST (quick, unbiased, and efficient statistical tree) classification method was used to establish the extraction model of ADL based on multiple indicators. The ADL time series dataset was extracted from 2000 to 2015, and the characteristics of ADL and its spatial-temporal dynamics were analyzed. These results were combined with meteorological data and socioeconomic statistics to discuss the main factors influencing ADL. The results showed that, by the end of 2015, the total area of ADL was 32,633 km2, accounting for 26.02% of the study area. The slight, moderate, severe, and extremely severe ADL accounted for 51.39%, 34.11%, 10.31%, and 4.20%, respectively. The total area of ADL decreased significantly at a rate of 2388.60 km2 y-1 from 2000 to 2015. The decreasing area was dominated by the slight and moderate ADL. The reversal of ADL exhibited significant correlations with an increase of annual precipitation and a decrease of annual maximum wind velocity (p < 0.01). The impact of annual maximum wind velocity on ADL is more important than annual precipitation. Increases in population density and the number of livestock did not promote the development of ADL. A series of ecological protection projects and policies created advantageous conditions for the reversal of ADL. This research provides a new method for monitoring ADL and useful information for controlling and managing aeolian desertification in this region. PMID- 30292994 TI - Pollution and children's health. AB - FINDINGS: The Lancet Commission on Pollution and Health found that pollution - air, water, soil, and chemical pollution - was responsible in 2016 for 940,000 deaths in children worldwide, two-thirds of them in children under the age of 5. Pollution is inequitably distributed, and the overwhelming majority of pollution related deaths in children occurred in low- and middle-income countries (LMICs). Most were due to respiratory and gastrointestinal diseases caused by polluted air and water. Pollution is linked also to multiple non-communicable diseases (NCDs) in children including low birth weight, asthma, cancer and neurodevelopmental disorders, and these diseases are on the rise. The full impact of pollution, especially chemical pollution on the global burden of pediatric disease is not yet known, but almost certainly is undercounted because patterns of chemical exposure are not well charted and the potential toxicity of many chemical pollutants has not been characterized. The list of pediatric NCDs attributed to pollution will likely expand as the health effects of newer chemical pollutants are better defined and additional associations between pollution and disease are discovered. CONCLUSION: Pollution prevention presents a major, largely unexploited opportunity to improve children's health and prevent NCDs, especially in LMICs. Failure to incorporate pollution prevention into NCD control programs is a major missed opportunity for disease prevention.

AB - Microplastics are frequently detected in freshwater environments, serving as a new factitious substrate for colonization of biofilm-forming microorganisms. Distinct microbial assemblages between microplastics and surrounding waters have been well documented; however, there is insufficient knowledge regarding biofilm colonization of plastic and non-plastic substrates, despite the fact that microbial communities generally aggregate on natural solid surfaces. In this study, the effects of substrate type on microbial communities were evaluated by incubation of biofilms on microplastic substrates (polyethylene and polypropylene) and natural substrates (cobblestone and wood) for 21 days under controlled conditions. Results from high-throughput sequencing of 16S rRNA revealed that the alpha diversity (richness, evenness, and diversity) was lower in the microplastic-associated communities than in those on the natural substrates, indicating substrate-type-coupled species sorting. Distinct community structure and biofilm composition were observed between these two substrate types. Significantly higher abundances of Pirellulaceae, Phycisphaerales, Cyclobacteriaceae, and Roseococcus were observed on the microplastic substrates compared with the natural substrates. Simultaneously, the functional profiles (KEGG) predicted by Tax4Fun showed that the pathways of amino acid metabolism and metabolism of cofactors and vitamins were increased in biofilms on the microplastic substrates. The findings illustrate that microplastic acts as a distinct microbial habitat (compared with natural substrates) that could not only change the community structure but also affect microbial functions, potentially impacting the ecological functions of microbial communities in aquatic ecosystems.

AB - The correlation amongst exposure to ultrafine particle concentrations and heart rate in a large healthy population was investigated. The study was conducted by continuously monitoring for seven days fifty volunteers in terms of exposure to particle concentrations, heart rate and physical activity performed through portable monitors. Data were analyzed adopting a linear mixed model able to manage the obtained repeated measures and to recognize a general trend resulting from the subject-specific patterns. Results show that the short-term exposure to ultrafine particle concentrations is positively associated with the heart rate for the different physical activities of the subject investigated (laying down, sitting, standing positions). In particular, a logarithmic correlation was recognized with a sharper increase of about 4-6 bpm for a variation of the particle number concentration of 2 * 104 part/cm3 and a slighter effect for further increases of about 0.1-0.2 * 10-4 bpm/(part/cm). CAPSULE: A positive correlation can be associated between the exposure to ultrafine particles and the heart rate.

AB - Removal of Sr2+ from aqueous media presents particular challenges, especially in complex wastes such as nuclear industry liquors. Commercial sorbents while effective, can be highly expensive and subject to negative effects from competing ions. Here we evaluate two potential biosorbents (crab carapace and spent distillery grain) as potential alternatives and compare their performance to two commercial sorbents for Sr2+ removal at industrially relevant concentrations (low mg/L). Physical and structural characterization of the materials was undertaken, and batch and dynamic studies were performed on Sr2+ solutions and simulated nuclear wastewater. Sorption performance was quantified with respect to contact time, initial concentration and ion-competition. Removal efficiencies were 20-70% for the biosorbents compared to 55-95% for the commercial materials. Results indicated sorption was predominantly through monolayer coverage on homogenous sites and could be described using a pseudo-second-order kinetic model. Studies with the simulant liquor showed Sr2+ sorption was reduced by 10-40% due to ion competition for sites. Characterization of biosorbents before and after Sr2+ sorption suggested that outer-sphere complexation and ion-exchange were the primary Sr2+ removal mechanisms. The efficiency of crab carapace for Sr2+ removal from aqueous media (with adsorption capacity 3.92 mg/g.) at industrially relevant concentrations, together with its mechanical stability, implementation and disposal cost, makes it a competitive option compared to other biosorbents and commercial materials reported in the literature. PMID- 30292998 TI - Testing the performance of one and two box models as tools for risk assessment of particle exposure during packing of inorganic fertilizer. AB - Modelling of particle exposure is a useful tool for preliminary exposure assessment in workplaces with low and high exposure concentrations. However, actual exposure measurements are needed to assess models reliability. Worker exposure was monitored during packing of an inorganic granulate fertilizer at industrial scale using small and big bags. Particle concentrations were modelled with one and two box models, where the emission source was estimated with the fertilizer's dustiness index. The exposure levels were used to calculate inhaled dose rates and test accuracy of the exposure modellings. The particle number concentrations were measured from worker area by using a mobility and optical particle sizer which were used to calculate surface area and mass concentrations. The concentrations in the worker area during pre-activity ranged 63,797-81,073 cm 3, 4.6 * 106 to 7.5 * 106 MUm2 cm-3, and 354 to 634 MUg m-3 (respirable mass fraction) and during packing 50,300 to 85,949 cm-3, 4.3 * 106 to 7.6 * 106 MUm2 cm-3, and 279 to 668 MUg m-3 (respirable mass fraction). Thus, the packing process did not significantly increase the exposure levels. Chemical exposure was also under control based on REACH standards. The particle surface area deposition rate in respiratory tract was up to 7.6 * 106 MUm2 min-1 during packing, with 52% 61% of deposition occurring in the alveolar region. Ratios of the modelled and measured concentrations were 0.98 +/- 0.19 and 0.84 +/- 0.12 for small and big bags, respectively, when using the one box model, and 0.88 +/- 0.25 and 0.82 +/- 0.12, when using the two box model. The modelling precision improved for both models when outdoor particle concentrations were included. This study shows that exposure concentrations in a low emission industrial scenario, e.g. during packing of a fertilizer, can be predicted with a reasonable accuracy by using the concept of dustiness and mass balance models. PMID- 30292999 TI - Characterizing the removal routes of seven pharmaceuticals in the activated sludge process. AB - The removal routes of pharmaceuticals especially biodegradation routes in the activated sludge process are still unclear. Some studies indicated pharmaceuticals were mainly removed via nitrification process (autotrophic biodegradation), while others suggested pharmaceuticals were mainly removed via COD degradation process (heterotrophic biodegradation). These unclear problems limited the improvements of pharmaceuticals removal. In this study, in order to elucidate three biodegradation routes (nitrification, COD degradation, or both nitrification and COD degradation), autotrophic and heterotrophic reactors were individually developed to separate nitrification and COD degradation form the activated sludge process (mix-trophic process including nitrification and COD degradation). Furthermore, the pharmaceuticals removal routes of adsorption, hydrolysis, and oxidation were also studied. Among six degradable pharmaceuticals, heterotrophic biodegradation and adsorption were the major removal routes. Two sulfonamides of five antibiotics were predominantly removed by COD degradation process, while nitrification and adsorption had no contributions. Adsorption, hydrolysis, nitrification, and COD degradation were the main elimination routes of cefalexin. COD degradation and adsorption were the dominant removal routes of norfloxacin. Tetracycline was mainly removed by the adsorption route, and hydrolysis and oxidation also played a role. For two drugs, ibuprofen was removed mainly via nitrification and COD degradation, and no adsorption occurred. Diclofenac could not be removed at all and was persistent in the aerobic conditions. Kinetic studies showed that biodegradation of the two sulfonamides, cefalexin, norfloxacin, and ibuprofen followed first-order kinetics rather than zero-order or second-order kinetics. PMID- 30293000 TI - The occurrence of contaminants of emerging concern in Slovenian and Croatian wastewaters and receiving Sava river. AB - This study investigated the occurrence of 48 contaminants of emerging concern (CECs) in wastewater effluents from three Slovenian and three Croatian waste water treatment plants (WWTPs) representing the major inputs into the upper and middle course of the Sava River and simultaneously in the Sava River itself. Two sampling campaigns were carried out (May and July 2017). Samples were extracted using solid-phase extraction and analysed by gas chromatography - mass spectrometry. In effluents, 23 CECs were >LOQ with caffeine and the UV-filter 4 hydroxybenzophenone (H-BP) present in the highest concentrations (<49,600 ng L-1 and <28,900 ng L-1, respectively) and most frequently detected (detection frequency; DFr > 83.3%). Bisphenol B and E were detected for the first time in WW from Velika Gorica (May) and Zapresic (July), respectively. In surface water (SW), 19 CECs were detected >LOQ with CAF again being the most abundant and most frequently detected (DFr = 92.9%). Bisphenols AP, CL2, P and Z were detected >LOQ for the first time in European SW. Active pharmaceutical ingredients naproxen, ketoprofen, carbamazepine and diclofenac; the preservative methyl paraben; CAF and UV-filter HM-BP were the most abundant CECs in SW and WW. An increasing trend in the total CEC load downstream was observed, indicating the cumulative effects of individual sources along the river. The Croatian Zapresic, Zagreb and Velika Gorica WWTP effluents contributed the most towards the enhanced loads of the CECs studied probably due to their size or insufficient treatment. HM-BP was the only compound found at a levels exhibiting high environmental risk (RQ = 1.13) downstream from Ljubljana and Domzale-Kamnik WWTPs. Other SW samples that contained HM-BP, ibuprofen (API) and/or benzyl paraben (preservative) posed a medium risk to the environment. The results suggest the need for further monitoring of CECs in the Sava River Basin. PMID- 30293001 TI - Trace metal characterization and fluxes from the Guadiana, Tinto-Odiel and Guadalquivir estuaries to the Gulf of Cadiz. AB - Metals transported into the coastal zone by the South Iberian rivers are key to understand the biogeochemical cycles and distribution of trace elements in the Gulf of Cadiz (GoC hereinafter) and the exchange with the Mediterranean Sea. Previous studies carried out in the 80s have suggested that metal enrichment in the Alboran Sea (Western Mediterranean) is related with fluvial inputs from acid mine drainage from the Tinto and Odiel rivers. The present study evaluates the contribution of dissolved trace metal concentrations (i.e. Cd, Co, Cu, Fe, Mo, Ni, Pb, V, Zn) from the three main rivers discharging into the GoC (i.e. Guadiana, Tinto-Odiel and Guadalquivir rivers). Our results show that the metal composition of water discharged from each river is impacted by the activities developed in the course of the rivers, which clearly influence the GoC coastal surface waters composition. Metal fluxes from the Guadalquivir river are quantitatively higher than those from the Tinto-Odiel (e.g. up to 73% and 19% higher for Ni and Cu, respectively). Although the metal concentrations spatial distributions in the GoC are dominated by the circulation pattern between the Atlantic and the Mediterranean Sea, the concentrations within the GoC continental shelf could be explained by a greater contribution from the Guadalquivir estuary (e.g. 80.5%, 54.6%, 56.5% and 56.6% for Ni, Cu, Mo, and V respectively). PMID- 30293002 TI - Zero-waste algal biorefinery for bioenergy and biochar: A green leap towards achieving energy and environmental sustainability. AB - In spite of tremendous efforts and huge investments on resources, biodiesel from oleaginous microalgae has not yet become a commercially viable and sustainable alternative to petro-diesel. This is mainly because of the technological and economic challenges hovering around large scale cultivation and downstream processing of algae, water and land usage, stabilized production technology, market forces and government policies on alternative energy and carbon credits. This review attempts to capture and analyse the global trends and developments in the areas of biofuel and bio-product of microalgae and proposes possible strategies that can be adopted to produce biofuel, biochar and bio-products utilizing wastewater in a bio-refinery model. The strategies include "Zero waste discharge" concept with process integration, wherein microalgae is grown strategically using different wastewater combined with flue gas in cultivation system for simultaneous production of 'high-value-low-volume' product and 'low value-high-volume' product with sharing of the remnant biomass to produce biochar. In addition, the CO2 present in the atmosphere is captured and sequestered long term in the form of biochar would help to attain carbon negativity, while remediating wastewater and balancing energy requirements. Therefore, "Zero waste discharge" concept holds the potential to make the process a sustainable one, while gaining on the carbon credits. PMID- 30293003 TI - Investigation of environmental Kuznets curve for ecological footprint: The role of energy and financial development. AB - Climate change has become a global phenomenon due to its threat to sustainable development. However, economic development plays a complementary role in both climate change and sustainability. Thus, the environmental Kuznets curve hypothesis is critical to climate change policy formulation and development strategies. Accordingly, this study examined the validity of environmental Kuznets curve hypothesis by investigating the relationship between economic growth, energy consumption, financial development, and ecological footprint for the period from 1977 to 2013 in 11 newly industrialized countries. For this purpose, the study employed both augmented mean group (AMG) estimator and heterogeneous panel causality method which are suitable for dependent and heterogeneous panels. The results of the estimator show that there is an inverted U-shaped relationship between economic growth and ecological footprint. According to the causality test results, it is concluded that there is bi-directional causality between economic growth and ecological footprint. PMID- 30293004 TI - Eco-friendly non-biocide-release coatings for marine biofouling prevention. AB - Environmental concerns have been changing the way of looking for solutions to problems. The hydrosphere, together with its biosphere, has been feeling the impact of many pollutants, used for instance in the marine industry for economic reasons or lack of knowledge of their effects. In particular biocides, applied as coatings in paints, are released into the waters becoming toxic and persistent extending their action to an area far beyond the initial coated surface they should protect. In order to minimize these side effects, two biocides, Irgarol (I) and Econea (E), were covalently attached to polyurethane (PU) and foul release silicone based (PDMS) marine paints through an isocyanate linker. Their antifouling bioactivity was better in PDMS coatings, both for single (Econea) and combined biocides (E/I ratio = 1.5) with contents lower than 0.6 wt%. The treated samples remained almost clean after more than one year immersion in the Portuguese shore of the Atlantic Ocean, and after about 24 weeks under the tropical conditions of Singapore (Fouling rate < 1%). Complementary biofilm adhesion susceptibility tests against Pseudoalteromonas tunicata D2 showed adhesion reduction higher than 90% for PU formulations containing single biocides and close to 100% for PDMS with combined biocides. The eco-toxicity assessment evidenced a low environmental impact, in accordance with the European standards. In addition, shipping field trial tests showed the best antifouling performance for the Econea-based PDMS formulations (E = 0.6 wt%), which remained clean for about nine months in open seawaters, proving the efficacy of this non-release strategy, when applied under dynamic conditions. PMID- 30293005 TI - Organotin contamination in commercial and wild oysters from China: Increasing occurrence of triphenyltin. AB - Organotin contamination in marine environment has been a public concern for many years due to its adverse impacts on biota and human health. This study investigated levels, distribution and health risks of six organotin compounds: tributyltin (TBT), dibutyltin (DBT), monobutyltin (MBT), triphenyltin (TPhT), diphenyltin (DPhT) and monophenyltin (MPhT) in commercial and wild oysters in China. The total organotin in commercial oysters ranged from 251 to 1949 ng Sn g 1 dw (dry weight) >. Two endocrine disruptors TBT and TPhT were detected in these samples with the highest level of 68.1 +/- 20.1 ng Sn g-1 dw and 747 +/- 7.3 ng Sn g-1 dw, respectively. For wild oysters, the concentrations of total organotins varied from 33.3 to 2671 ng Sn g-1 dw. Butyltins were dominated by TBT with the mean level of 26.1 +/- 30.0 ng Sn.g-1 dw and showed no significant spatial variation between the southern and northern coastal zones (p > 0.05). However, compared with the north, phenyltin levels especially TPhT were much higher in the south coastline (246-1484 ng Sn.g-1 dw) due to the wider use of TPhT-based biocides in local mariculture and agriculture. Health risk assessment indicated that a daily exposure of TPhT-contaminated oysters (including commercial and wild ones) may pose adverse threats to human particularly children as the risk quotients (RQ) were higher than 1. Organotin contamination (e.g., TPhT) still occurs in the South China's coastal zones after the TBT ban, which deserves future research and effective measures to protect the marine ecosystem and human health. PMID- 30293006 TI - Mercury and other trace metals in lettuce (Lactuca sativa) grown with two low salinity shrimp effluents: Accumulation and human health risk assessment. AB - Shrimp farming effluents from two sources of low-salinity water, well water (WW) and diluted seawater (DSW) (salinity, 1.7 g L-1; electrical conductivity, 2.7 dS m-1), were used to grow lettuce (L. sativa) in order to assimilate the nutrients present in shrimp effluents and produce edible biomass. The two treatments, WW and DSW, were tested in triplicate. Additionally, one hydroponic system in triplicate was constructed to grow lettuce using a nutritive solution as the control treatment (HS). The production variables of lettuce in the two crop varieties (Parris Island (VPI) and Tropicana M1 (VTM1)) showed a general trend of DSW > HS > WW with regards to the size, weight and total foliage, except for the number of leaves, which was higher with HS treatment than with WW and DSW treatments. The accumulation of Cu, Hg, Mn and Zn in edible lettuce tissue and the health risk by the intake of lettuce were evaluated. Heavy metal concentrations in edible lettuce tissue for the three treatments showed the same trend of Mn > Zn > Cu > Hg, with concentration ranges of 47.1 to 188.7, 35.7 to 66.2, 4.1 to 6.4, and 0.01 to 0.02 mg kg-1 (dry weight), respectively. Such concentrations did not exceed the safe limits (CAC, 1984). The health risk index and target hazard quotient were <1, which indicates that the population exposed to these metals due to intake from lettuce consumption is unlikely to have adverse health effects when shrimp farming effluents are used to grow lettuce plants. PMID- 30293007 TI - Pollution characteristics in a dusty season based on highly time-resolved online measurements in northwest China. AB - To investigate the pollution characteristics and potential sources in a dusty season, an online analyzer was used to measure trace gases and major water soluble ions in PM10 from April 1st to May 29th, 2011 in Lanzhou. The average concentrations of HONO, HNO3, HCl, SO2 and NH3 were 0.93, 1.16, 0.48, 9.29 and 5.54 MUg/m3, respectively, and 2.8, 2.76, 8.28 and 2.48 MUg/m3 for Cl-, NO3-, SO42- and NH4+. In the non-dust period, diurnal variations of SO42-, NO3- and their gaseous precursors showed similar change trend. NH4+ showed unimodal pattern whereas NH3 illustrated a bimodal pattern. HCl and Cl- showed an opposite diurnal pattern. In the dust event, temporal profiles of HCl and Cl-, SO2 and SO42- all presented similar change trend, and SO42- and Cl- preceded dust ions (Ca2+ and Mg2+) 13 h. The ratios of NO3- to SO42- were 0.65 in the non-dust period and 0.31 in the dust event. In the dust event, the sulfur oxidation ratio (SOR) was a factor of 1.33 greater than that in the non-dust period, and [SO42 ]/[SO2] was 2.31 times of that in the non-dust period. The source apportionment using Probabilistic Matrix Factorization (PMF) suggested that fugitive dust (58.09%), secondary aerosols (33.98%), and biomass burning (7.93%) were the major sources in the non-dust period whereas dust (67.01%), salt lake (29.68%), biomass burning (0.8%), and motor vehicle (2.51%) were the primary sources in the dust event. Concentration weighted trajectory (CWT) model indicated that NO3-, Cl- and K+ could be regarded as local source species, the potential sources of Na+, Mg2+ and Ca2+ concentrated in the two large areas with the one covered in the junction areas of Xinjiang, Qinghai and Gansu and another one covered the places around in Lanzhou, the potential sources of SO42- were mainly localized in the areas adjacent to Lanzhou. PMID- 30293008 TI - In situ generation of H2O2 using MWCNT-Al/O2 system and possible application for glyphosate degradation. AB - Hydrogen peroxide (H2O2), as a green oxidant, has been widely applied into advanced oxidation processes (AOPs) for the degradation of toxic organic pollutants. The in situ generation of H2O2 can not only improve the storage and transportation safety of H2O2 but also reduce the capital and operation costs. In the present work, a novel system, i.e., multi-walled carbon nanotube-aluminum (MWCNT-Al) composite was used to in situ generate H2O2 through micro electrolysis. The MWCNT-Al composite was characterized and optimized. The accumulation concentration of H2O2 reached 947 mg/L at the initial pH of 9.0, the MWCNT-Al composite dosage of 8 g/L and oxygen gas flow rate of 400 mL/min after 60 min. The in situ generation of H2O2 was achieved by MWCNT-Al/O2 system, mainly owing to the direct contact between Al0 and MWCNT in MWCNT-Al composite, which accelerated the transfer of electrons from Al0 to O2, as well as the excellent electrocatalytic activity of MWCNT toward the two-electron reduction of oxygen. When H2O2 in situ generation technology was used in peroxone process (O3/H2O2 process) to degrade glyphosate in aqueous solution, the removal efficiency of TOC and total phosphorus was 68.35% and 73.27%, respectively. Finally, the possible mechanism of in situ generation of H2O2 in MWCNT-Al/O2 system was temporarily proposed. PMID- 30293009 TI - Linking global climate change to local water availability: Limitations and prospects for a tropical mountain watershed. AB - Bridging the gap between the predictions of coarse-scale climate models and the fine-scale climatic reality is a key issue of hydrological research and water management. While many advances have been realized in developed countries, the situation is contrastingly different in most tropical regions where we still lack information on potential discrepancies between measured and modeled climatic conditions. Consequently, water managers in these regions often rely on non academic expertise to help them plan their future strategies. This issue is particularly alarming in tropical mountainous areas where water demand is increasing rapidly and climate change is expected to have severe impacts. In this article, we addressed this issue by evaluating the limitations and prospects in using regional climate models for evaluating the impact of climate change on water availability in a watershed that provides Quito, the capital of Ecuador, with about 30% of its current water needs. In particular, we quantified the temporal and spatial discrepancies between predicted and observed precipitation and temperature, and explored underlying mechanisms at play. Our results provide a strong critique of the inappropriate use of regional models to inform water planning with regard to adaptation strategies to face climate change. As a multidisciplinary group composed of hydrologists, ecologists and water managers, we then propose a framework to guide future climate change impact studies in tropical mountain watersheds where hydro-climatological data are scarce. PMID- 30293010 TI - Understanding the global hydrological droughts of 2003-2016 and their relationships with teleconnections. AB - Droughts often evolve gradually and cover large areas, and therefore, affect many people and activities. This motivates developing techniques to integrate different satellite observations, to cover large areas, and understand spatial and temporal variability of droughts. In this study, we apply probabilistic techniques to generate satellite derived meteorological, hydrological, and hydro meteorological drought indices for the world's 156 major river basins covering 2003-2016. The data includes Terrestrial Water Storage (TWS) estimates from the Gravity Recovery And Climate Experiment (GRACE) mission, along with soil moisture, precipitation, and evapotranspiration reanalysis. Different drought characteristics of trends, occurrences, areal-extent, and frequencies corresponding to 3-, 6-, 12-, and 24-month timescales are extracted from these indices. Drought evolution within selected basins of Africa, America, and Asia is interpreted. Canonical Correlation Analysis (CCA) is then applied to find the relationship between global hydro-meteorological droughts and satellite derived Sea Surface Temperature (SST) changes. This relationship is then used to extract regions, where droughts and teleconnections are strongly interrelated. Our numerical results indicate that the 3- to 6-month hydrological droughts occur more frequently than the other timescales. Longer memory of water storage changes (than water fluxes) has found to be the reason of detecting extended hydrological droughts in regions such as the Middle East and Northern Africa. Through CCA, we show that the El Nino Southern Oscillation (ENSO) has major impact on the magnitude and evolution of hydrological droughts in regions such as the northern parts of Asia and most parts of the Australian continent between 2006 and 2011, as well as droughts in the Amazon basin, South Asia, and North Africa between 2010 and 2012. The Indian ocean Dipole (IOD) and North Atlantic Oscillation (NAO) are found to have regional influence on the evolution of hydrological droughts. PMID- 30293011 TI - Characterization of water soluble inorganic ions and their evolution processes during PM2.5 pollution episodes in a small city in southwest China. AB - PM2.5 samples were collected in four segregate one-month periods, each representing one season, for analyzing their contents of water soluble inorganic ions (WSIIs) in a small city inside Sichuan Basin. Daily PM2.5 concentrations ranged from 23.2 to 203.1 MUg m-3 with an annual mean of 66.9 +/- 33.6 MUg m-3. Annual mean concentrations of WSIIs was 28.8 +/- 20.3 MUg m-3, accounting for 43.1% of PM2.5. Seasonal mean concentrations of WSIIs ranged from 17.5 +/- 9.3 MUg m-3 in summer to 46.5 +/- 27.6 MUg m-3 in winter. Annual mean mass ratio of NO3-/SO42- was 0.49, demonstrating predominant stationary sources for secondary inorganic aerosols (SNA, including SO42-, NH4+ and NO3-); whereas annual mean molar ratio of [NH4+]/[NO3-] was 3.5, suggesting dominant agriculture emissions contributing to the total nitrogen. During a severe and long-lasting (13 days) winter pollution period when mean PM2.5 concentration reached to 132.5 MUg m-3, PM2.5 concentration was enhanced by a factor of 2.6 while that of SNA by a factor of 2.9 compared to those before the pollution event, and the fraction of SNA in PM2.5 only increased slightly (from 46.7% to 50.6%). Thus, local accumulation of pollutants under poor diffusion conditions played a major role causing the extremely high PM2.5 concentration, besides the contributions from the enhanced SNA formation under specific weather conditions. PMID- 30293013 TI - The role of gender in the structure of networks of childhood adversity. AB - The objective of present study is to investigate the relationship between different childhood adversities. The potential impact of early adversity on prevention programs is discussed. Data on twelve childhood adversities was collected from a representative sample of 5037 members of the general population living in a large metropolitan area. Data were analyzed through network analysis, to estimate and compare network connectivity and centrality measures by gender. Over half the respondents had been exposed to at least one adversity during their earlier developmental stage. Among adversity-exposed persons, 48.4% presented simultaneous adversities, most of which were related to 'family dysfunction' and 'maltreatment' (mean = 2.9 adversities). Women reported more adversities than men (59.0% vs. 47.6%). Although the 'global' network connectivity across adversities was similar in both genders, 'regional' distinctions in the network structure were found. While 'neglect' and 'parental death' were more important for women than men, 'parental mental disorders' was more important for men. Gender-related childhood adversities were clustered experiences. Adversities related to 'early family dysfunction' and 'maltreatment' were prominent features in the networks of both boys and girls. Differential preventive and intervention programs should take into account gender-related patterns of exposure and reporting patterns of early adversity. PMID- 30293012 TI - M1 Macrophage Polarization Is Dependent on TRPC1-Mediated Calcium Entry. AB - Macrophage plasticity is essential for innate immunity, but in-depth signaling mechanism(s) regulating their functional phenotypes are ill-defined. Here we report that interferon (IFN) gamma priming of naive macrophages induces store mediated Ca2+ entry and inhibition of Ca2+ entry impairs polarization to M1 inflammatory phenotype. In vitro and in vivo functional analyses revealed ORAI1 to be a primary contributor to basal Ca2+ influx in macrophages, whereas IFNgamma induced Ca2+ influx was mediated by TRPC1. Deficiency of TRPC1 displayed abrogated IFNgamma-induced M1 inflammatory mediators in macrophages. In a preclinical model of peritonitis by Klebsiella pneumoniae infection, macrophages showed increased Ca2+ influx, which was TRPC1 dependent. Macrophages from infected TRPC1-/- mice showed inhibited expression of M1-associated signature molecules. Furthermore, in human patients with systemic inflammatory response syndrome, the level of TRPC1 expression in circulating macrophages directly correlated with M1 inflammatory mediators. Overall, TRPC1-mediated Ca2+ influx is essential for the induction/shaping of macrophage polarization to M1 inflammatory phenotype. PMID- 30293014 TI - Psychomotor agitation in subjects hospitalized for an acute exacerbation of Schizophrenia. AB - The aims of this study were to establish the prevalence of moderate and severe psychomotor agitation in patients hospitalized for an active phase of schizophrenia, the associations between psychomotor agitation and patients' demographic and clinical variables, the intra-individual stability of the agitated/non-agitated dichotomy in independent psychotic breakdowns. The study was performed on a database relative to 630 inpatients hospitalized with a diagnosis of schizophrenia. Psychomotor agitation was measured with the Positive and Negative Syndrome Scale - Excited Component (PANSS-EC). Prevalence of moderate and severe psychomotor agitation was 40.5% and 23.7%, respectively. Non agitated patients were older, with longer illness history and duration of untreated psychosis, were more frequently on antipsychotic medication, had lower incidence of recent use of substances, and functioned better before the index hospitalization than moderately and/or severely agitated patients. Non-agitated patients had lower scores for total PANSS and Emsley's positive and anxiety dimensions. Compared with the severely agitated group, non-agitated and moderately agitated patients scored more in Emsley's depression dimension. Poor functioning before index hospital admission, higher scores for negative subscale and Emsley's positive dimension and use of substances exerted an effect on risk of psychomotor agitation. PMID- 30293016 TI - PHACTR1 regulates oxidative stress and inflammation to coronary artery endothelial cells via interaction with NF-kappaB/p65. AB - BACKGROUND AND AIMS: Genome-wide association studies have showed that genetic variants in phosphatase and actin regulator 1 (PHACTR1) are associated with coronary artery disease and myocardial infarction. However, the underlying mechanism of PHACTR1 in atherosclerosis remains unknown. METHODS: Immunoblots were performed to evaluate the expression of PHACTR1 and phosphorylation of NF kappaB signaling. Reactive oxygen species (ROS) labeled with DCFH-DA were assessed by flow cytometry. Fluorescence microscope was used to detect the translocation of p65 in human coronary artery endothelial cells (HACECs). Co immunoprecipitation was performed to determine the interaction of PHACTR1 with MRTF-A. RESULTS: The mRNA and protein levels of PHACTR1 were markedly increased in carotid plaquescompared with normal carotid arteries. Immunofluorescence staining indicated that PHACTR1 was constitutively expressed in endothelial cells in carotid plaques. Knockdown of PHACTR1 reduced excessive ICAM-1, VCAM-1 and VE cadherin expression induced by oxidized low density lipoprotein (ox-LDL) in HCAECs. Additionally, silencing PHACTR1 alleviated p47phox phosphorylation and intracellular oxidative stress reflected by the reduction of ROS. Molecular experiments revealed that knockdown of PHACTR1 attenuated NF-kappaB activity without affecting IkappaBalpha and IKKalpha/beta phosphorylation. In contrast, nuclear translation of p65 was blocked by depletion of PHACTR1. Furthermore, co immunoprecipitation showed that PHACTR1 interacted with MRTF-A and p65 in HCAECs. Knockdown of MRTF-A suppressed the interaction of PHACTR1 with p65, subsequently blocking the nuclear translocation of p65. CONCLUSIONS: Our finding suggest that silencing PHACTR1 alleviates the nuclear accumulation of p65 and NF-kappaB via interaction with MRTF-A, ensuing attenuating oxidative stress and inflammation in HCAECs.

AB - BACKGROUND: Personal care product chemicals may be contributing to risk for asthma and other atopic illnesses. The existing literature is conflicting, and many studies do not control for multiple chemical exposures. METHODS: We quantified concentrations of three phthalate metabolites, three parabens, and four other phenols in urine collected twice during pregnancy from 392 women. We measured T helper 1 (Th1) and T helper 2 (Th2) cells in their children's blood at ages two, five, and seven, and assessed probable asthma, aeroallergies, eczema, and lung function at age seven. We conducted linear and logistic regressions, controlling for additional biomarkers measured in this population as selected by Bayesian Model Averaging. RESULTS: The majority of comparisons showed null associations. Mono-n-butyl phthalate (MnBP) was associated with higher Th2% (RR: 10.40, 95% CI: 3.37, 17.92), and methyl paraben was associated with lower Th1% (RR: -3.35, 95% CI: -6.58, -0.02) and Th2% at borderline significance (RR: -4.45, 95% CI: -8.77, 0.08). Monoethyl phthalate was associated with lower forced expiratory flow from 25 to 75% of forced vital capacity (FEF25-75%) (RR: -3.22 L/s, 95% CI: -6.02, -0.34). Propyl paraben (OR: 0.86, 95% CI: 0.74, 0.99) was associated with decreased odds of probable asthma. CONCLUSIONS: While some biomarkers, particularly those from low molecular weight phthalates, were associated with an atopic cytokine profile and poorer lung function, no biomarkers were associated with a corresponding increase in atopic disease.

AB - The practical implementation of a performance measurement system is an inevitable necessity for all levels of management to direct business operations towards maximal efficiency. In particular, academics' and practitioners' expectations have resulted in notable initiatives that incorporate sustainability assessment in managerial decision-making. The sustainability paradigm investigates practices and policies that simultaneously account for economic, environmental, and social aspects. Drawing on the perspective of a sustainability-conscious decision maker, this paper centers on the evaluation of logistical locations with capacitated production levels through a two-phase assessment procedure. To design a supervisory framework to measure the sustainability performance of the supplying facilities under investigation, we develop a double bootstrap data envelopment analysis model with undesirable factors in the first phase. We, then, use the obtained bias-corrected efficiency estimates in the second phase to establish sustainability-based policies in the context of facility location problems. The proposed model is applied to an energy case study of fossil fuel power plants in the United States. We present empirical evidence corroborating a considerable difference between the results of the case where the decision maker explores the environmental and social impacts of the power plants and the conventional formulation by which only financial outcomes are considered. Our numerical findings reveal that the proposed approach substantially diminishes greenhouse gas emissions at the cost of slight increases in total expenses. In addition to such an improvement in the environmental efficiency, we provide evidence of a dramatic enhancement in the social performance.

AB - In the current context of strong urban sprawl, it becomes urgent to find urban approaches that simultaneously promote ecological functions and relationships between people and nature in cities. Streets are omnipresent urban elements that can deliver ecosystem services and facilitate people daily interactions with nature. Promoting vegetation in streets can take different forms which have to be combined with people's preferences. Based on photomontages, we assessed people's perceptions and valuations for herbaceous vegetation types associated to various managements and designs of pavements. Using a combination of a local field survey and a French national online survey, we collected a total of 3609 responses representing a large diversity of socio-demographic characteristics. The results of the field survey confirmed those of the online survey. Although there was variability among people valuations, we found that lowly managed pavements with spontaneous vegetation were in average higher valued than highly managed pavements without vegetation. Pavements with spontaneous vegetation were perceived as less kept than pavements without vegetation, but more beautiful and less boring. We found a consensus of high valuations towards pavements containing vegetation integrated in small design interventions (flowers seeded in foot of wall, design of a meadow strip along the pavement), suggesting that people generally accept vegetation with visible signs of human actions or managements. Socio-demographic characteristics partly explained variabilities in photo valuations. As expected, people frequently connected with nature had the highest preferences for vegetated pavements, spontaneous or integrated in designs. These results show that vegetated streets can become daily biodiversity-friendly urban greenspaces appreciated by urban dwellers. We provide recommendations for promoting vegetation in streets that will be useful for politics, urban designers and managers. PMID- 30293019 TI - Countries' classification by environmental resilience. AB - Rapid population growth, urbanization, and industrialization affect countries' vulnerability to future disasters. This study investigates the vulnerability of 141 countries to natural and anthropogenic hazards using six environmental indicators including air pollution, greenhouse gas (GHG) emissions, access to drinking water, access to improved sanitation, environmental risks (total death and affected people), and energy use. Results confirm that the resilience varies by the location. Furthermore, this work delineates the World countries using the environmental resilience score. The most resilient countries are located in Europe and North America and the least resilient countries are in Africa and Asia. Based on the results, Estonia and Ethiopia are the most and the least resilient countries, respectively. Integrated results can highlight resilient cities as a guide for other regions. PMID- 30293020 TI - Influential parameters on natural weathering under harsh climatic conditions of mechanically recycled plastic film specimens. AB - In this work, real life reclaimed plastic solid waste (PSW) secured from the municipal sector was mechanically recycled and compounded with virgin linear low density polyethylene (LLDPE). The compounding of the plastic film samples utilised the means of extrusion and blown filming to produce various formulations of the blends containing up to 100% (by weight) of the PSW in the examined specimens. The film samples were compared to market products used in the State of Kuwait where PSW accumulation presents a major obstacle. Natural weathering under arid and harsh climatic conditions was also performed to determine the degradation extent of the film samples. Haze (%), light transmission (%) and the total change in colour (DeltaE) were measured as indicators to the degradation profile of the polymeric materials, in addition to tensile pull mechanical properties. Properties were noted to deteriorate as a function of weathering time and waste content. Statistical analysis was also performed on the properties measured and climatic conditions including airborne pollutants levels. The abundance of the secondary airborne pollutant (ozone) was determined to be a significant variable on the studied properties. This can be attributed to induced photo-oxidation the polymeric matrix is subjected to under such climatic conditions which increases oxygen diffusion throughout the polymeric matrix. Future development of the recycled blends studied in this work can be a route for the decrease of associated environmental stressors with virgin plastic resin conversion. PMID- 30293021 TI - Introduction of the circular economy within developing regions: A comparative analysis of advantages and opportunities for waste valorization. AB - The introduction of effective solid waste management strategies in developing countries should be considered for improving sustainability at global level. Many barriers should be overcome, concerning the introduction of environmental policies, effective investments, social inclusion and public awareness, which are significant issues in low-middle income countries. The Circular Economy could represent the answer for improving current solid waste management activities worldwide, since denote the principle of waste valorization and recycling for boosting developing economies. This paper is focused on this theme, analyzing main opportunities for improving the current state of solid waste management in developing big cities. The solid waste management of two countries are reviewed: Romania is the emerging country where Circular Economy is becoming a future objective due to economic aids and strength regulations which the European Union (EU) established for the nations forming parts the alliance; as a comparison, Bolivia is reported for evaluating main differences founded for developing recycling systems in a no-EU country. These two case studies could be of interest for highlighting main pros and cons of the participation into a wide organization like the EU for introducing in short terms Circular Economy principles. Moreover, a theoretical Circular Economy model for developing big cities in low-middle income countries is described within the study for effectively comparing which chances can spread for these countries as regard municipal solid waste exploitation. Despite the economic level, Romania and Bolivia are both facing with many solid waste management issues although in different magnitude. For the Romanian case study, it is visible how it cannot achieve the European goals for 2020 due the need of change in public recycling behavior. Bolivia, instead, represents the case where international aids and new investments are required, considering the informal sector into the formal management system as a real opportunity for improving local recycling rate. In conclusion, the comparison suggests how external supports led to implement the principles of the Circular Economy within a developing region. The model of Circular Economy proposed is recommended for developing big cities in order to advance a new form of safe employment, encouraging the activities that are still in action (i.e. informal sector) and boosting the principles of sustainable development. PMID- 30293022 TI - Determinants of perceived risk and liability concerns associated with prescribed burning in the United States. AB - While prescribed burning is a proven tool in the management of forests and grasslands, its use has been limited due, in part, to potential risks that may result in legal liability, property damage, and personal injury. The purpose of this study is to understand the factors that shape landowners' and fire professionals' perceptions of risks associated with prescribed burning activities. The data for this study were collected from active prescribed fire professionals involved in Prescribed Burn Association (PBA) activities in 14 Southern and Mid-western states. Perceived risk was higher among respondents with higher levels of concern related to safety and weather but lower among respondents with more experience in burning activities. Sociodemographic variables such as age and income were not significantly correlated with risk perception. These findings are useful for better understanding how landowners and fire professionals perceive risk and offer insight into how perceived risk affects decisions to apply prescribed burns. PMID- 30293023 TI - Elimination kinetics and detoxification mechanisms of microcystin-LR during UV/Chlorine process. AB - Microcystin-LR (MC-LR), a toxin produced by cyanobacteria, is very toxic and poses a threat to public health when entering water treatment works. In this study, UV/chlorine process, as an advanced oxidation process (AOP), has been demonstrated for effective elimination of MC-LR levels and associated toxicity. At a chlorine dose of 3.0 mg L-1 and UV fluence of 125 mJ cm-2, MC-LR (initial concentration 1.0 MUM) was reduced by 92.5%, which was much higher than 20.3% removal under UV irradiation alone and 65.1% removal during dark chlorination. Enhanced degradation was attributed by hydroxyl radicals (HO) and reactive chlorine species (RCS), mainly Cl2- and ClO. Increasing chlorine doses or lowering pH favored MC-LR removal. Increased bicarbonate and natural organic matter concentrations inhibited MC-LR removal, but bromide ions enhanced MC-LR removal instead. MC-LR elimination rates in natural waters were roughly two times smaller than those in ultrapure water. The reactive radicals promoted hydroxylation of both diene of Adda moiety and double bond of Mdha moiety in MC LR. UV exposure enhanced the dechlorination of chloro-MC-LR via the cleavage of CCl bond. The toxicity was evaluated by a protein phosphatase (PP2A) inhibition assay. At a chlorine dose of 3.0 mg L-1 and UV fluence of 125 mJ cm-2, the toxicity of the treated water was reduced by 75.0%, which was also higher than 25.7% and 46.7% removal under UV irradiation alone and during dark chlorination, respectively. These results highlight UV/chlorine is an efficient AOP for MC-LR degradation and detoxification. PMID- 30293024 TI - Organic contaminated sediments remediation with active caps: Nonlinear adsorption unveiled by combined isotherm and column transportation studies. AB - Bench-scale column studies were performed with four cap materials (sand, apatite, organoclay and granular activated carbon) for five target compounds (toluene, naphthalene, phenanthrene, pyrene and dichlorobiphenyl) to represent a range of cap materials and pollutants (volatile & semi-volatile compounds) commonly found in sediments. Two moment-derived methods were used to model cap performance. Rough agreement was observed between the column experiments and modeling data with the fronting and tailing effects identified from certain breakthrough curves indicating a high potential of non-linear adsorption. Distribution coefficients (kd) were experimentally determined with isotherm studies together with measurements of surface area and microporosity of the cap materials via nitrogen adsorption porisimetry. These studies unveiled the occurrence of nonlinear adsorption by Freundlich simulation. The effects of nonlinear adsorption of the cap were further explored via modeling. Results suggested better prediction of cap performance assuming nonlinear adsorption instead of linear adsorption results based upon the risk of release for a 30-year period. PMID- 30293025 TI - Biodegradation study of methadone by adapted activated sludge: Elimination kinetics, transformation products and ecotoxicological evaluation. AB - The biotransformation study of difficult-to-degrade opioid analgesic methadone (MTHD) was performed by activated sludge culture adapted to high concentration of methadone (10 mg/L). The study included determination of elimination kinetics of the parent compound, taxonomic characterization of microbial culture, identification of biotransformation products (TPs) and assessment of ecotoxicological effects of biotransformation processes. The chemical analyses were performed by ultra-performance liquid chromatography/quadrupole-time-of flight mass spectrometry, whereas the ecotoxicological assessment was made based on determinations of toxicity to freshwater algae. Changes of the adapted sludge culture during the experiment were followed using the 16S rRNA gene amplicon sequencing. Depending on the experimental conditions, the elimination efficiency of methadone (10 mg/L) varied from 9% to 93% with the corresponding half-lives from 11.4 days to 1.5 days. A significantly faster elimination (t1/2 from 1.5 days to 5.8 days) was achieved at cometabolic conditions, using glucose containing media, as compared to the experiments with MTHD as a single organic carbon source (t1/2 = 11.4 days). Moreover, increased biotransformation rate following the additional supplementation of ammonia, revealed a possible importance of nitrogen availability for the transformation at cometabolic conditions. The elimination of parent compound was associated with the formation of 3 different TPs, two of which were identical to main human metabolites of MTHD, 2-Ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) and 2-ethyl-5 methyl-3,3-diphenyl-1-pyrroline (EMDP). EDDP represented over 90% of the total TP concentration at the end of experiment. The biodegradation of MTHD was associated with a pronounced drop in algal toxicity, confirming a rather positive ecotoxicological outcome of the achieved biotransformation processes. PMID- 30293026 TI - Deep seepage of per- and polyfluoroalkyl substances through the soil of a firefighter training site and subsequent groundwater contamination. AB - Per- and polyfluoroalkyl substances (PFASs) are utilized in specific firefighting foams. The objectives of this study were i) to map PFAS distribution in the soil and groundwater of a firefighter training site active for more than 3 decades, ii) to locate the main points of entry of PFASs into the aquifer and iii) to identify which PFASs seeped most deeply into the soil. A total of 44 soil cores and 17 groundwater samples were collected. Perfluorooctane sulfonate (PFOS), 6:2 fluorotelomer sulfonic acid (6:2 FTSA) and 6:2 Fluorotelomer sulfonamide alkylbetaine (6:2 FTAB) were the most predominant PFASs in surface soil. The highest total PFAS concentrations (up to 357 MUg/g) were measured in two areas. Both areas were considered as potential points of entry of PFASs into the aquifer since PFASs were detected in soil 15 m below the surface, despite the presence of clay layers. The highest total PFAS concentrations were recorded in the monitoring wells located in the perimeter of the firefighter training site and in the spring located downgradient in the direction of groundwater flow. They ranged from 300 to 8300 ng/L. The fluorotelomer 6:2 FTAB was quantified in 6 monitoring wells, suggesting that this FT can reach a water table 20 m below the ground's surface. PMID- 30293027 TI - A biomimetic SiO2@chitosan composite as highly-efficient adsorbent for removing heavy metal ions in drinking water. AB - Highly efficient adsorbents for drinking water purification are demanded since the contaminants are generally in a low concentration which makes it difficult for conventional adsorbents. Herein, we present a novel biomimetic SiO2@chitosan composite as adsorbent with a high adsorption capability towards heavy metal ions including As(V) and Hg(II). The hollow leaf-like SiO2 scaffold within the adsorbent has a stable chemical property; while on the surface SiO2, the chitosan nanoparticle provide a large amount of active sites such as amino and hydroxyl groups for adsorbing heavy metal ions. The special SiO2 structure also prevents the agglomeration and loss of chitosan, which enables the efficient contact between the functional groups of chitosan and heavy metal ions. The SiO2@chitosan composite exhibits maximum adsorption capacities of 204.1 and 198.6 mg g-1 towards Hg(II) and As(V), respectively. In addition, the removal efficiency reaches over 60% within 2 min. The adsorption performance enables the presented biomimetic adsorbent suitable for adsorbing low-concentration heavy metal ions, especially possessing a promising potential for drinking water purification. PMID- 30293028 TI - Designing biochar properties through the blending of biomass feedstock with metals: Impact on oxyanions adsorption behavior. AB - Metal-blending of biomass prior to pyrolysis is investigated in this work as a tool to modify biochar physico-chemical properties and its behavior as adsorbent. Six different compounds were used for metal-blending: AlCl3, Cu(OH)2, FeSO4, KCl, MgCl2 and Mg(OH)2. Pyrolysis experiments were performed at 400 and 700 degrees C and the characterization of biochar properties included: elemental composition, thermal stability, surface area and pore size distribution, Zeta potential, redox potential, chemical structure (with nuclear magnetic resonance) and adsorption behavior of arsenate, phosphate and nitrate. Metalblending strongly affected biochars' surface charge and redox potential. Moreover, it increased biochars' microporosity (per mass of organic carbon). For most biochars, mesoporosity was also increased. The adsorption behavior was enhanced for all metal-blended biochars, although with significant differences across species: Mg(OH)2-blended biochar produced at 400 degrees C showed the highest phosphate adsorption capacity (Langmuir Qmax approx. 250 mg g-1), while AlCl3-blended biochar produced also at 400 degrees C showed the highest arsenate adsorption (Langmuir Qmax approx. 14 mg g-1). Significant differences were present, even for the same biochar, with respect to the investigated oxyanions. This indicates that biochar properties need to be optimized for each application, but also that this optimization can be achieved with tools such as metal-blending. These results constitute a significant contribution towards the production of designer biochars.

AB - In the present work, palm wood was pretreated using hydrothermal technique in conjunction with chemical method for removal of lignin. Pretreated palm wood was subjected to hydrolysis using Trichoderma reesei MTCC 4876. Subsequently bioethanol was produced using palm wood hydrolysate by Kluveromyces marxianus MTCC 1389. RSM was used to identify the non-linear relationship and optimize various process parameters such as parameters such as pH, temperature, agitation rate, substrate concentration and inoculum size for bioethanol production. ANN constructed with 5-2-1 topology was also used to optimize process parameters. The experimental bioethanol yield of 22.90 g/l was obtained at ANN optimum conditions of temperature 45 degrees C, agitation rate 156 rpm, pH 5, substrate concentration 8% (v/v) and inoculum size 3.2% (v/v). PMID- 30293030 TI - Characterization of aerobic granular sludge used for the treatment of petroleum wastewater. AB - The application of aerobic granular sludge (AGS) is a promising biological method for wastewater treatment. In the present study, the AGS method was used for the treatment of petroleum wastewater. The granulation process and organic/nitrogen compound removal efficiencies were determined and correlated with the microbiological communities. Granulation of the aerobic sludge occurred after 35 days of operation. The compacted granules had a diameter of 0.46-0.9 mm. Extracellular polymeric substances (EPS) contents increased as granulation progressed and reached 128 mg/g.VSS. The granulated sludge efficiently reduced COD by 95% and petroleum compound contents by 90%. NH4+-N and TN removal were inefficient due to the inhibition of nitrobacteria and denitrificans, but were significantly improved by the addition of glucose. The microorganisms in the granules capable of degrading petroleum chemicals consisted of the genera Propioniciclava, Micropruina, Alphaproteobacteria, Flavobacterium, and Sulfuritalea. PMID- 30293031 TI - A promising laccase immobilization approach for Bisphenol A removal from aqueous solutions. AB - The immobilization of crude laccase from Trametes pubescens by glutaraldehyde crosslinking prior to entrapment into Ca-alginate beads increased the immobilization yield by 30% and reduced the leaking by 7-fold compared to the immobilization with no crosslinking. The performance of the newly developed biocatalyst to degrade Bisphenol A (BPA) from aqueous solutions was tested. Thus, operating at optimal conditions (i.e. pH 5, 30 degrees C, 20 mg L-1 BPA and 1500 U L-1 laccase), a BPA removal higher than 99% in 2 h was achieved. This value is higher than those reported to date for BPA removal by immobilized laccases. In addition, the biocatalyst was able to remove BPA in 10 successive batches with an efficiency higher than 70% at the end of the last batch. BPA adsorption on the alginate beads was negligible, therefore BPA removal was only due to laccase action. Moreover, Fourier-transform Infrared (FTIR) spectroscopy suggested BPA transformation by laccase. PMID- 30293032 TI - Targeted knockout of phospholipase A2 to increase lipid productivity in Chlamydomonas reinhardtii for biodiesel production. AB - Biofuel derived from microalgae have several advantages over other oleaginous crops, however, still needs to be improved with its cost aspect and can be achieved by developing of a strain with improved lipid productivity. In this study, the CRISPR-Cas9 system was incorporated to carry out a target-specific knockout of the phospholipase A2 gene in Chlamydomonas reinhardtii. The targeted gene encodes a key enzyme in the Lands cycle. As a result, the mutants showed a characteristic of increased diacylglycerol pool, followed by a higher accumulation of triacylglycerol without being significantly compensated with the cell growth. As a result, the overall lipid productivities of phospholipase A2 knockout mutants have increased by up to 64.25% (to 80.92 g L-1 d-1). This study can provide crucial information for the biodiesel industry. PMID- 30293033 TI - Effects of biochar size and type on gaseous emissions during pig manure/wheat straw aerobic composting: Insights into multivariate-microscale characterization and microbial mechanism. AB - Greenhouse gas and ammonia emissions during composting with different biochar types and particle sizes were investigated. Compared with powder-biochar, granular-biochar improved pore connectivity and was benefit to methanotrophs activities, like Methylococcaceae, reducing CH4 emissions. At the same particle size, bamboo biochar (BB) had a higher pore volume and more aerobic microenvironment within the compost than rice straw biochar (RSB), reducing GHG emissions. Bamboo biochar had high aromatic compound and NO3- concentrations and therefore surface pi-pi electron donor/acceptor interactions, causing low N2O emissions and inhibiting denitrifying bacteria (e.g., Bacteroidales). More CO and CO bonds in rice straw biochar than bamboo biochar caused lower NH3 emissions using rice straw than bamboo biochar. Powdered biochar had more exposed reactive functional groups and decreased NH3 production better than granular biochar. Powdered bamboo biochar controls gaseous emissions better than other biochars during aerobic pig manure/wheat straw composting. PMID- 30293034 TI - The study of exercise tests in paroxysmal kinesigenic dyskinesia. AB - OBJECTIVE: To unravel if there was muscular ion channel dysfunction in paroxysmal kinesigenic dyskinesia (PKD) patients using the exercises tests (ET). METHODS: Sixty PKD patients including 28 PRRT2 mutations carriers were enrolled in this study, as well as 19 hypokalaemic periodic paralysis (HypoPP) patients as the positive controls and 45 healthy subjects as the negative controls. ET including long exercise test (LET) and short exercise test (SET) was performed in the corresponding subjects. RESULTS: In the LET, both the overall PKD patients and HypoPP patients had greater CMAP amplitude and area increments during exercise than healthy controls. At most 25% of PKD patients were identified from the normality with greater amplitude increment than the area. On the contrary, 50% of HypoPP patients were differentiated with greater area increment than the amplitude. More percentage of PRRT2- patients than PRRT2+ patients had abnormal average amplitude increment. Unexpectedly, five PKD patients had abnormal maximum CMAP amplitude decrements after exercise in the LET, and one had abnormal maximum immediate amplitude decrement in the SET. CONCLUSIONS: Distinct ET manifestations were found in PKD patients compared to normal controls and HypoPP patients. SIGNIFICANCE: Abnormal muscle membrane excitability might be involved in the mechanisms responsible for PKD. PMID- 30293035 TI - Chronic exposure to copper and zinc induces DNA damage in the polychaete Alitta virens and the implications for future toxicity of coastal sites. AB - Copper and zinc are metals that have been traditionally thought of as past contamination legacies. However, their industrial use is still extensive and current applications (e.g. nanoparticles and antifouling paints) have become additional marine environment delivery routes. Determining a pollutant's genotoxicity is an ecotoxicological priority, but in marine benthic systems putative substances responsible for sediment genotoxicity have rarely been identified. Studies that use sediment as the delivery matrix combined with exposures over life-history relevant timescales are also missing for metals. Here we assess copper and zinc's genotoxicity by exposing the ecologically important polychaete Alitta virens to sediment spiked with environmentally relevant concentrations for 9 months. Target bioavailable sediment and subsequent porewater concentrations reflect the global contamination range for coasts, whilst tissue concentrations, although elevated, were comparable with other polychaetes. Survival generally reduced as concentrations increased, but monthly analyses show that growth was not significantly different between treatments. The differential treatment mortality may have enabled the surviving worms in the high concentration treatments to capture more food thus removing any concentration treatment effects for biomass. Using the alkaline comet assay we confirm that both metals via the sediment are genotoxic at concentrations routinely found in coastal regions and this is supported by elevated DNA damage in worms from field sites. However, combined with the growth data it also highlights the tolerance of A. virens to DNA damage. Finally, using long term (decadal) monitoring data we show stable or increasing sediment concentrations of these metals for many areas. This will potentially mean coastal sediment is a significant mutagenic hazard to the benthic community for decades to come. An urgent reappraisal of the current input sources for these 'old pollutants' is, therefore, required. PMID- 30293036 TI - Spatial and temporal variations of bulk and colloidal dissolved organic matter in a large anthropogenically perturbed estuary. AB - In the present study, we characterized the sources of dissolved organic matter (DOM) and the processes controlling the evolution of DOM in a large anthropogenically perturbed estuary in Southern China. Three-dimensional excitation emission matrices (3D EEMs) revealed that DOM in the estuary was primarily from autochthonous origin although terrestrial sources also contributed to the DOM production. Parallel factor analysis (PARAFAC) of the EEMs dataset indicated that DOM in the estuary was a legacy from the upstream wastewater discharging activities, and estuarine mixing was the primary mechanism responsible for the decreasing concentrations of DOM components. However, non conservative behavior of DOM components was also observed along the center transect as a result of additional removal process and spatial heterogeneity in the distribution of DOM. Seasonal influence on the concentrations and compositions of colloidal DOM in the estuary was also found. Asymmetric flow field-flow fractionation (AF4) analysis showed distinct distribution patterns of the colloidal DOM during the dry and wet seasons. Behavior of colloidal DOM was size-independent and the distribution of colloidal DOM was controlled by multiple depletion and replenishment cycles in the dry season, in contrast to those observed in the wet season. By combining both EEMs-PARAFAC modeling and AF4 technique, this study provided important information on the sources and fate of bulk and colloidal DOM in a large estuary with intensive anthropogenic influences. PMID- 30293037 TI - Enhanced bisphenol A removal from stormwater in biochar-amended biofilters: Combined with batch sorption and fixed-bed column studies. AB - A high-efficient, low-cost, and practical biochar implementation method is desired to extend biochar's powerful adsorption performance for environmental remediation. This study presents novel results with advanced biochar application by integrating biochar with biofilter for the removal of bisphenol A (BPA) from stormwater. Biochars derived from wood dust (BC0) at different pyrolytic temperatures (300, 500, and 700 degrees C, referred as, BC300, BC500, and BC700, respectively) were characterized and investigated for their adsorption of BPA under different pH levels and humic acid (HA) concentrations by batch sorption and fixed-bed column experiments. Microcosm biofilters vegetated with phragmites australis and amended with different biochars were constructed and used for BPA removal under different hydraulic loading rates (HLRs). Compared with other biochars, BC700 showed a high adsorption rate and capacity due to high specific surface area and pore volume. As a consequence, fixed-bed columns amended with BC700 can remove BPA more efficiently than columns with BC0, BC300, and BC500 from synthetic stormwater, though the treatment performance was affected relatively by pH change and HA concentration. A high correlation (r2 = 0.899) between the breakthrough time and the product of adsorption rate (k2) and capacity (Qmax) was found, which suggests that batch sorption experiments could be an efficient tool for prediction of breakthrough time. The BPA removal efficiency of microcosm biofilters amended with BC0, BC300, BC500 and BC700 for real stormwater containing 200 MUg/L BPA at HLR of 40 cm/h averaged 4.1, 10.8, 80.3, and 98.4%, which were about 6, 15, 115, and 141 times, respectively, compared to bilfitlers without biochar amendment. Moreover, biochar amendment not only enhanced the BPA removal but also promoted phragmites australis growth, elevated nutrients and increased the E. coli removal efficiency. Hence, biochar amended biofilters could be a promising approach for enhancing the elimination of endocrine-disrupting chemicals such as BPA from aqueous environments. PMID- 30293038 TI - DEHP toxicity on vision, neuromuscular junction, and courtship behaviors of Drosophila. AB - Bis(2-ethylhexyl) phthalate (DEHP) is the most common plasticizer. Previous studies have shown DEHP treatment accelerates neurological degeneration, suggesting that DEHP may impact retinal sensitivity to light, neurotransmission, and copulation behaviors. Although its neurotoxicity and antifertility properties have been studied, whether DEHP exposure disrupts vision and how DEHP influences neuromuscular junction (NMJ) have not been reported yet. Moreover, the impact of DEHP on insect courtship behavior is still elusive. Fruit flies (Drosophila melanogaster) were treated with series concentrations of DEHP and observed for lifespan, motor function, electroretinogram (ERG), electrophysiology of neuromuscular junction (NMJ), courtship behaviors, and relevant gene expression. Our results confirmed the DEHP toxicity on lifespan and capacity of motor function and updated its effect on copulation behaviors. Additionally, we report for the first time that DEHP exposure may harm vision by affecting the synaptic signaling between the photoreceptor and the laminar neurons. Further, DEHP treatment altered both spontaneous and evoked neurotransmission properties. Noteworthy, the effect of DEHP exposure on the copulation behavior is sex dependent, and we proposed potential mechanisms for future investigation. PMID- 30293039 TI - Contamination, health risk, mineralogical and morphological status of street dusts- case study: Erbil metropolis, Kurdistan Region-Iraq. AB - Street dusts contamination by heavy metals (HMs) and polycyclic aromatic hydrocarbons (PAHs), their mineralogical and morphological properties were investigated in Erbil metropolis. A total of 43 soil and street dust samples were collected and analyzed, and SPSS, ImageJ, X-powder and positive matrix factorization (PMF) software were used for data analyzing. Results showed the role of geology in mineralogical status of dusts. Based on ImageJ software processing, dust particles with diameters below 10 MUm and low circularity and roundness were dominant. The enrichments for Hg, Cu, Pb and Zn contents were observed in compare with their calculated local geochemical baselines and geoaccumulation index, while, Ni, Co and Cr were categorized as particularly unpolluted. However, Hg, Cu and Pb showed the highest ecological risk (Eji) values among the studied elements, and 25.80%, 25.80% and 12.90% of the samples were classified as very high, moderate and considerable potential ecological risks, respectively. Hazard index (HI) followed the decreasing order of Pb > Cr > Cu > Ni > Hg > Zn > Co, and ingestion was the main exposure route particularly for children. The concentrations of individual PAHs ranged from 1.06 to 1000 ng/g, with the dominance of 3 and 4-ring compounds. Also, non-carcinogenic PAHs concentrations were higher than carcinogenic compounds and toxic equivalents (TEQs) ranged from 22.30 to 246.92 ng/g, with a max value in Northern industrial zone. Finally, source identification using multivariate statistics and PMF introduced three main PAHs and HMs sources in the study area including geogenic, traffic and industries, and incinerators (mainly for medical wastes).

AB - Sugars and n-alkanes are important organic constituents of atmospheric fine particulate matter (PM2.5). For better understanding their sources and seasonal variations in urban atmosphere, sugar compounds (anhydrosugars, sugars and sugar alcohols) and homologue n-alkanes (C18-C37) were studied in PM2.5 samples collected from September 2013 to July 2014 in Beijing, China. In general, all measured compounds showed the lowest levels in summer. Higher concentrations of sugar compounds and n-alkanes were observed in winter, probably due to elevated combustion emissions (e.g., coal, biofuel and agricultural residue burning) and stable meteorological conditions during heating season. Levoglucosan was the major sugar species in all seasons particularly in autumn and winter, highlighting the significant contribution of biomass burning to fine organic aerosols throughout the whole year especially in cold seasons. Plant waxes contributed to n-alkanes the most in late spring (54.5%) and the least in winter (11.6%); while fossil fuel combustion had the largest contribution in winter (385 ng m-3). The weak odd-carbon predominance of n-alkanes in wintertime aerosols also suggests fossil fuel combustion as the important source of organic aerosols in the heating season. Soil resuspension, fossil fuel combustion and biomass burning, and secondary sources are the main sources of OC in PM2.5 at Beijing. The seasonal variation in source contributions indicates that meteorological condition is a key factor in controlling PM2.5 levels. Furthermore, dust storms in spring can strongly enhance the atmospheric level of fine organic matter in Beijing.

AB - Given probable the increment in the nutritional needs of both humans and animals, animal production will have increased dramatically by 2050. Insect meals could be an alternative protein source for livestock, and they would also be able to reduce the environmental problems related to intensive animal production system. The aim of this study was to evaluate productive performance, blood analysis, nutrient digestibility, and changes in the internal organs of laying hens fed Hermetia illucens larvae meal (HI) at two different levels in substitution (25 or 50%) of soybean meal (SBM). A total of 162 Hy-line Brown hens (sixteen weeks old) were equally divided into three experimental groups and fed isoprotein and isoenergetic diets. Egg weight, feed intake, and feed conversion rate were not affected by the soybean meal substitution at both inclusion levels of insect meal. Egg mass was positively affected by the insect meal diets, as was the lay percentage, although only at the lowest inclusion level. Dry matter, organic matter, and crude protein digestibility coefficients were lower for the HI50 diet, probably due to the negative effect of chitin. A reduction in serum cholesterol and triglycerides was observed in both insect-meal fed groups, while serum globulin level increased only at the highest level of insect meal inclusion, and, consequently, the albumin to globulin ratio decreased. Overall, a protein replacement of 25% with an insect meal from Hermetia illucens larvae in the diet of laying hens seems to be more suitable and closer to the optimal level.

AB - Rectangular shaped alpha-Ce2S3 microrods have been grown with the aid of a facile, efficient, low cost and low temperature chemical bath deposition (CBD) approach in thin film form. Characterizations of alpha-Ce2S3 have been performed through structural, morphological and surface wettability studies. Intermixed rectangular microrods with lower contact angle provide a reduction in intrinsic resistance and effective ion diffusion path during electrochemical activities ensuring maximum utilization of the active electrode species. This leads to achieve a remarkable specific capacitance of 726 F/g at 2 mV/s scan rate with the excellent electrochemical stability of 93% at 2000 CV cycles. Efficient electrochemical findings exhibit excellent scope of alpha-Ce2S3 towards next generation energy storage devices. PMID- 30293043 TI - Copper-indium-sulfide colloids on quantum dot sensitized TiO2 solar cell: Effects of capping with mercapto-acid linker molecules. AB - The copper-indium-sulfide (CIS) ternary colloids were synthesized in "green" water solvent at room temperature employing mercapto-alkyl carboxylic linker molecules such as thioglycolic acid (TGA), thioacetic acid (TAA), 2 mercaptopropionic acid (2-MPA) and l-cysteine (Cys). The stability of the CIS colloids is strongly influenced by the structures of linker molecules, and short linker molecules induce strong adsorption of the CIS colloids on the TiO2, exhibiting strong visible-light absorption and high photo-conductivities. Effects of linker molecules capping CIS colloids on the solar cell performances were demonstrated. The solar cell performances for the CIS-TiO2 improve as an increase of photo-conductivity of the CIS-TiO2 electrodes. In particular, the CIS(TAA) TiO2 photoelectrode employing the shortest linker molecules (TAA) exhibited the highest PCE yielding with 6.33% (short-circuit current: 14.0 mA/cm2, open-circuit voltage: 0.91 V and fill factor: 48.0%). PMID- 30293044 TI - The effect of chelating anions on the retention of Co(II) by gamma-alumina from aqueous solutions under the unadjusted pH condition of supported catalyst preparation. AB - This study analyzes the effect of the addition of acetate, citrate, and nitrilotriacetate anions on the retention of Co(II) cations by the gamma-alumina surface in view of the preparation of alumina supported cobalt catalysts. The emphasis was placed on the way the Co(II) species attach to the solid surface when adsorbed from aqueous solutions under the unadjusted pH condition. The individual adsorption isotherms onto gamma-Al2O3 support for cobalt and a given ligand were determined by following the solution depletion method in single solute and bi-solute systems. These adsorption data were supplemented by the results of potentiometric titrations. In the case of bi-solute systems, the adsorption procedures allowed either co-impregnation of gamma-alumina with equimolar solutions of cobalt and ligand salts or pre-impregnation of gamma alumina with the ligand anions and the subsequent adsorption of cobalt. Changes in the pH of the equilibrium solid-liquid suspension were also monitored along the adsorption isotherms. The adsorption of Co(II) onto gamma-Al2O3 in the presence of acetate and nitrilotriacetate led to the formation of the type A (i.e., solid-metal-ligand) ternary complexes. The use of citrate anions together with Co(II) cations was shown to improve the impregnation process through the formation of ternary complexes of type B (i.e., solid-ligand-metal). The comparison with a system containing tricarballylate anions allowed concluding that the presence of the hydroxyl group in the citrate anion enhanced its affinity for the alumina surface by contributing to the inner-sphere character of its surface-bound complexes.

AB - Pseudocapacitive electrode materials employed in supercapacitors may bring in high energy density (ED) and specific capacitance (Csc), which are critical for their practical applications. Accordingly, logical design of advanced electrode materials is highly demanded to progress high-performance supercapacitors. Here, for the first time, we suggest a straightforward route for the synthesis of NiGa2S4-rGO as an advanced cathode material supported on nickel foam (NF) for employed in flexible solid-state asymmetric supercapacitors (FSASCs). Due to an abundant ratio of active sites and large surface area of the NiGa2S4-rGO advanced material, the as-prepared NiGa2S4-rGO/NF electrode illustrates considerable electrochemical properties including remarkable specific capacitance (Csc) of 2124.34 F g-1 with excellent rate capability of 73%, and exceptional durability, which are better than NiGa2S4/NF and previously reported transition metal sulfides (TMSs). Furthermore, for the first time a pseudocapacitive advanced anode material of FeSe2-rGO have been successfully fabricated on a nickel foam (NF) substrate by a facile strategy. Element Selenium as the favorable element was offered into the Fe for enhancement and adjustment of the anode material electrochemical performance. The FeSe2-rGO/NF advanced anode electrode presents satisfactory electrochemical properties containing an exceptional specific capacitance (Csc) of 432.40 F g-1, significant rate performance of 57.84% and superior durability, which are better than FeSe2/NF electrode and previously studied Fe-based anode material. Considering the remarkable electrochemical performance of the as-prepared pseudocapacitive advanced electrode materials, a FSASC based on the NiGa2S4-rGO/NF as the cathode electrode and FeSe2-rGO/NF as the anode electrode was assembled. The FSASC device delivers superior Csc of 341.20 F g-1, outstanding energy density (ED) of 121.31 W h kg-1, remarkable cycle stability (only 7.30% damage after 5000 charge/discharge (CD) cycles). PMID- 30293046 TI - Understanding heat driven gelation of anionic cellulose nanofibrils: Combining saturation transfer difference (STD) NMR, small angle X-ray scattering (SAXS) and rheology. AB - A novel mechanism of heat-triggered gelation for oxidised cellulose nanofibrils (OCNF) is reported. We demonstrate that a synergistic approach combining rheology, small-angle X-ray scattering (SAXS) and saturation transfer difference NMR (STD NMR) experiments enables a detailed characterisation of gelation at different length scales. OCNF dispersions experience an increase in solid-like behaviour upon heating as evidenced by rheological studies, associated with enhanced interfibrillar interactions measured using SAXS. Interactions result in an increased fibrillar overlap and increased population of confined water molecules monitored by STD NMR. In comparison, cationic cellulose nanofibrils (produced by reaction of cellulose with trimethylglycidylammonium chloride) were found to be heat-unresponsive. PMID- 30293047 TI - Iron species supported on a mesoporous zirconium metal-organic framework for visible light driven synthesis of quinazolin-4(3H)-ones through one-pot three step tandem reaction. AB - A bioinspired iron(III)porphyrinic Zr-MOF, PCN-222(Fe), was modified by post synthetic cluster metalation with iron(III) chloride, as a cheap, earth-abundant, and environmentally friendly metal precursor, towards formation a new multifunctional MOF, namely Fe@PCN-222(Fe). The MOF consists of bimetallic (Zr oxo-Fe) nodes linked by Fe(III)porphyrin struts. The cluster metalation and pre activation treatment of PCN-222(Fe) were performed cooperatively using the FeCl3. The respective MOF was characterized through various techniques, such as FT-IR, PXRD, ICP-AES, BET surface area, SEM, UV-Vis DRS, TGA/DSC, PL, and XPS analyses. The solid showed catalytic activity for one-pot tandem synthesis of quinazolin 4(3H)-ones from alcohols and 2-aminobenzamide through a three-consecutive-step reaction (oxidation-cyclization-oxidation) under visible light irradiation using air or oxygen without adding any additive. In addition, its catalytic performance was superior to that of the bare PCN-222(Fe) and the corresponding homogeneous catalysts. The experiments indicate that the solid MOF acts as both a photoredox and Lewis acid catalyst. Hot-filtration and Fe-leaching tests as well as reusability experiments confirm that the nominal MOF acts as an efficient reusable heterogeneous catalyst for at least three runs without significant decrease in its activity. This work demonstrates the potential of using MOFs as supports for single-site metal species towards preparation of multifunctional MOFs for modern organic transformations combining photocatalysis and catalysis. PMID- 30293048 TI - A systematic review of qualitative studies exploring peer learning experiences of undergraduate nursing students. AB - BACKGROUND: Peer learning experiences have been reported in previous qualitative studies, however individual findings could limit practical leverage due to small sample size. Thus it is necessary to integrate invaluable findings from various qualitative studies to consider appropriateness and acceptability of peer learning in professional nurse education. OBJECTIVE: To identify and synthesize qualitative evidence of peer learning experiences of undergraduate nursing students so as to understand their perceptions on peer learning experiences. DESIGN: A qualitative systematic review was conducted in accordance with the Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) statement. DATA SOURCES: Database searching was conducted on electronic databases such as Cumulative Index to Nursing and Allied Health Literature (CINAHL), Science Direct, and MEDLINE that published from 2007 to 2017. REVIEW METHODS: Qualitative studies were appraised using the Critical Appraisal Skills Programme (CASP). Thematic analysis was used to analyse the data using line by line coding, organising coding into descriptive themes, and interpreting further to generate new insights. RESULTS: Six studies were included in this review. The most common themes identified were integrated into two new insights including personal development and professional development. CONCLUSION: This review has revealed that peer learning experiences contribute to the learning process of undergraduate nursing students in preparing them to become professional nurses through personal development and professional development. PMID- 30293049 TI - Effects of sodium fluoride on the reproductive development of Bombyx mori. AB - Bombyx mori was used as a model to evaluate the reproductive toxicity of NaF in insects. Significant reduction in cocoon quality, survival rate, fecundity, and hatchability were observed upon NaF treatment groups. Fluoride determination indicated that F- has a cumulative effect on the gonad of silkworm. High performance liquid chromatography revealed that the testosterone content of males was decreased in NaF-treated groups, and enzyme-linked immunosorbent assay showed that the estradiol content was decreased in NaF-treated females. Ultrastructural observation of testicles of silkworm larvae revealed mitochondrial turgescence, endoplasmic reticulum destruction, the appearance of vacuoles and lysosomes, and apoptosis and necrosis of cells in NaF-treated groups. Altered tail length and tail DNA content in Comet assays further confirmed DNA damage in NaF-treated larvae. We demonstrated reproductive toxicity of fluoride toward silkworm at physiological and biochemical levels, and the results provide a theoretical basis for revealing the reproductive toxicity of fluoride in terrestrial insects. PMID- 30293050 TI - No regional gray matter volume reduction observed in young Japanese people at ultra-high risk for psychosis: A voxel-based morphometry study. AB - OBJECTIVES: Structural brain magnetic resonance imaging studies of individuals at ultra-high risk (UHR) for psychosis have shown subtle but widespread reductions in baseline gray matter volume (GMV) in the frontal, temporal, and limbic regions compared with healthy controls (HC). These regions coincide with regions of reduced GMV in patients with established psychosis and have led to the consideration of structural changes in UHR as a potential biomarker for future transition to psychosis. However, most studies have been from Europe, North America, and Australia, with few reports from other regions, and two recent studies from Asian countries have failed to detect regional GMV reduction in UHR, suggesting the need for further analysis of an Asian sample. In this study, we investigated GMV reduction in Japanese UHR subjects. RESULTS: The study used voxel-based morphometry to compare magnetic resonance imaging brain scans between 45 UHR individuals recruited by a specialist and 33 HCs. This showed no significant GMV reduction in the UHR group compared with the healthy control group. This negative result may be attributable to characteristics of Asian samples, such as a low prevalence of illicit drug use, or to the heterogeneous nature of UHR subjects. PMID- 30293051 TI - Gallic acid inhibits the expression of keratin 16 and keratin 17 through Nrf2 in psoriasis-like skin disease. AB - Gallic acid (GA), a natural small molecule found in Radix Paeoniae Rubra, has a variety of favorable biological activities. However, the anti-psoriasis effect of GA has never been explored up to now. This study evaluates the protective effect of GA on psoriasis-like skin disease both in vitro and in vivo and explores the underlying mechanism. The results show that GA significantly decreases the mRNA and protein expression of keratin 16 and keratin 17 which are the markers of psoriasis. Additionally, GA obviously ameliorates psoriasis area and severity index scores and decreases the epidermal hyperplasia of psoriasis-like disease mice. The activity of Nrf2 which targets keratin 16 and keratin 17 is significantly downregulated by GA. Furthermore, the downregulation of keratin 16 and keratin 17 induced by GA was abolished by the Nrf2-overexpression in vitro. This study initially elucidates the anti-psoriasis effect and mechanism of GA which hints that GA would be a potential candidate for the treatment of psoriasis.

PMID- 30293053 TI - Educational intervention to improve critical thinking for undergraduate nursing students: A randomized clinical trial. AB - The objective of this study was to compare the effectiveness of Problem Based Learning (PBL) versus PBL associated with the Active Learning Model for Critical Thinking (ALMCT) to improve critical thinking (CT) in nursing students in an educational intervention on Basic Life Support (BLS). A two-arm randomized, single-blinded, parallel clinical trial was carried out with 108 Brazilian undergraduate nursing students who participated in a BLS course. PBL + ALMCT was used in the control group (CG), and PBL was used in the experimental group (EG). Pre- and post-tests were used to evaluate CT dispositions using the California Critical Thinking Dispositions Inventory (CCTDI), and CT skills were evaluated using the California Critical Thinking Skills Test (CCTST). The results did not indicate significant differences between the CG and EG groups for total CCTDI and total CCTST scales and for most of their subscales. However, there was a significant difference in the EG when the mean scores on the pre- and post-test were compared on the CCTDI analyticity subscale (t = 2073; p = 0.043) and on the CCTST analysis subscale (t = 2302; p = 0.025). We strongly recommend further studies using PBL associated with ALMCT and randomized clinical trials that last more than one month. PMID- 30293054 TI - Rationale underpinning postgraduate student nurses' choice of research methods used for their masters' theses. AB - Many nurses in Taiwan use quantitative research for their master's thesis. However, qualitative research explores humankind in depth providing a more holistic approach relating to nursing. The purpose of this study was to explore the rationale postgraduate students used to choose the research methods for their masters' theses in Taiwan. A descriptive qualitative research design was used. Data were collected through semi-structured interviews of sixteen nursing students studying a master's from seven different Universities in Taiwan in 2016. Data were analyzed using thematic analysis. Finding revealed three themes (1) Students' personal and professional backgrounds; (2) Myths about quantitative research; (3) Misperceptions about qualitative research. Nurse educators could use these findings as a reference to design post-graduate nursing courses. It is essential to provide a balanced educative experience between delivering qualitative and quantitative modules to enhance respect of research method, knowledge and skills. Further, this could facilitate students' choice in research methods when designing their master's theses. PMID- 30293055 TI - Nuclear organization and morphology of cholinergic neurons in the brain of the rock cavy (Kerodon rupestris) (Wied, 1820). AB - The aim of this study was to conduct cytoarchitectonic studies and choline acetyltransferase (ChAT) immunohistochemical analysis to delimit the cholinergic groups in the encephalon of the rock cavy (Kerodon rupestris), a crepuscular Caviidae rodent native to the Brazilian Northeast. Three young adult animals were anesthetized and transcardially perfused. The encephala were cut in the coronal plane using a cryostat. We obtained 6 series of 30-MUm-thick sections. The sections from one series were subjected to Nissl staining. Those from another series were subjected to immunohistochemistry for the enzyme ChAT, which is used in acetylcholine synthesis, to visualize the different cholinergic neural centers of the rock cavy. The slides were analyzed using a light microscope and the results were documented by description and digital photomicrographs. ChAT immunoreactive neurons were identified in the telencephalon (nucleus accumbens, caudate-putamen, globus pallidus, entopeduncular nucleus and ventral globus pallidus, olfactory tubercle and islands of Calleja, diagonal band of Broca nucleus, nucleus basalis, and medial septal nucleus), diencephalon (ventrolateral preoptic, hypothalamic ventrolateral, and medial habenular nuclei), and brainstem (parabigeminal, laterodorsal tegmental, and pedunculopontine tegmental nuclei). These findings are discussed through both a functional and phylogenetic perspective. PMID- 30293056 TI - Intermittent voluntary ethanol consumption combined with ethanol vapor exposure during adolescence increases drinking and alters other behaviors in adulthood in female and male rats. AB - Epidemiological studies suggest that binge drinking is prevalent among adolescents, and may result in neurobehavioral consequences. Animal models provide the experimental control to investigate the consequences of "binge" alcohol exposure during this neurodevelopmental epoch. The current study used an animal model that combined an intermittent pattern of alcohol vapor exposure with voluntary drinking of 20% unsweetened alcohol in adolescent male and female Wistar rats (postnatal day [PD] 22-62), in order to test for potential differences in behavioral changes, ethanol drinking, and hypocretin/orexin (Hcrt/OX) signaling associated with exposure status. Two weeks after discontinuation of the alcohol vapor exposure and drinking during adolescence, rats were tested in adulthood for anxiety-like behaviors using a modified open field conflict task, pre-pulse facilitation of startle response, light/dark box, and marble burying test. Adolescent alcohol exposure led to overall decreased startle response and increased behavioral arousal in the light/dark chamber during adulthood. Additionally, male rats demonstrated more disinhibited behavior during the conflict task compared to females, and female rats exhibited more rearing behavior during the light/dark test. Rats were also given a 2-bottle choice test that resulted in adolescent alcohol-exposed rats drinking significantly more alcohol in adulthood. Further, female rats also consumed more alcohol in adulthood compared to males. Estrous cycle phase did not account for any of the sex differences observed in the behavioral measures. Histological results indicated that adolescent alcohol did not alter Hcrt/OX-1 or Hcrt/OX-2 receptor mRNA expression levels in adult rats compared to control adults. However, female rats expressed a higher level of Hcrt/OX-1 and Hcrt/OX-2 receptor mRNA in the frontal cortex compared to males. These data suggest that our current model of intermittent ethanol exposure in adolescence can modestly affect both behavior and future consumption of alcohol and that Hcrt/OX receptor signaling differs between males and females. PMID- 30293057 TI - UDP-glycosyltransferase family in Haemonchus contortus: Phylogenetic analysis, constitutive expression, sex-differences and resistance-related differences. AB - UDP-glycosyltransferases (UGT), catalysing conjugation of UDP-activated sugar donors to small lipophilic chemicals, are widespread in living organisms from bacteria to fungi, plant, or animals. The progress of genome sequencing has enabled an assessment of the UGT multigene family in Haemonchus contortus (family Trichostrongylidae, Nematoda), a hematophagous gastrointestinal parasite of small ruminants. Here we report 32 putative UGT genes divided into 15 UGT families. Phylogenetic analysis in comparison with UGTs from Caenorhabditis elegans, a free living model nematode, revealed several single member homologues, a lack of the dramatic gene expansion seen in C. elegans, but also several families (UGT365, UGT366, UGT368) expanded in H. contortus only. The assessment of constitutive UGT mRNA expression in H. contortus adults identified significant differences between females and males. In addition, we compared the expression of selected UGTs in the drug-sensitive ISE strain to two benzimidazole-resistant strains, IRE and WR, with different genetic backgrounds. Constitutive expression of UGT368B2 was significantly higher in both resistant strains than in the sensitive strain. As resistant strains were able to deactivate benzimidazole anthelmintics via glycosylation more effectively then the sensitive strain, UGT368B2 enhanced constitutive expression might contribute to drug resistance in H. contortus.

AB - Tritryps diseases are devastating parasitic neglected infections caused by Leishmania spp., Trypanosoma cruzi and Trypanosoma brucei subspecies. Together, these parasites affect more than 30 million people worldwide and cause high mortality and morbidity. Leishmaniasis comprises a complex group of diseases with clinical manifestation ranging from cutaneous lesions to systemic visceral damage. Antimonials, the first-choice drugs used to treat leishmaniasis, lead to high toxicity and carry significant contraindications limiting its use. Drug resistant parasite strains are also a matter for increasing concern, especially in areas with very limited resources. The current scenario calls for novel and/or improvement of existing therapeutics as key research priorities in the field. Although several studies have shown advances in drug discovery towards leishmaniasis in recent years, key knowledge gaps in drug discovery pipelines still need to be addressed. In this review we discuss not only scientific and non scientific bottlenecks in drug development, but also the central role of public private partnerships for a successful campaign for novel treatment options against this devastating disease. PMID- 30293059 TI - Polyunsaturated fatty acid elongation and desaturation in activated human T cells: ELOVL5 is the key elongase. AB - PUFAs are important constituents of membrane glycerophospholipids. However, changes in the capacities to incorporate and metabolize PUFAs when cells enter the cell cycle have not been thoroughly studied. In this study, differences in the incorporation and metabolism of exogenous PUFAs in resting and proliferating primary human T-cells and in the Jurkat cell line were measured. Overall, proliferating T-cells and Jurkat cells had a greater capacity to incorporate and elongate exogenous 18- and 20-carbon PUFAs compared with resting T-cells. Proliferating T-cells and Jurkat cells also showed a greater capacity to desaturate 18-carbon PUFA substrates. Consistent with these observations, a significant increase in the expression of fatty acid desaturase (FADS) 1, FADS2, and elongation of very long chain fatty acids protein (ELOVL) 5 was measured in proliferating T-cells compared with resting T-cells. No quantifiable ELOVL2 was measured. Knockdown of ELOVL5 in T-cells and Jurkat cells significantly affected cellular monounsaturated and PUFA profiles and strongly impaired the elongation of 18- and 20-carbon PUFAs. In conclusion, the induction of proliferation in human T-cells is associated with a significant increase in the capacity to take up and metabolize exogenous PUFAs, and ELOVL5 is responsible for the elongation of 18- and 20-carbon PUFAs in these cells. PMID- 30293061 TI - Parasitoid Jewel Wasp Mounts Multi-Pronged Neurochemical Attack to Hijack a Host Brain. AB - The parasitoid emerald jewel wasp Ampulex compressa induces a compliant state of hypokinesia in its host, the American cockroach Periplaneta americana through direct envenomation of the central nervous system (CNS). To elucidate the biochemical strategy underlying venom-induced hypokinesia, we subjected the venom apparatus and milked venom to RNAseq and proteomics analyses to construct a comprehensive "venome", consisting of 264 proteins. Abundant in the venome are enzymes endogenous to the host brain, including M13 family metalloproteases, phospholipases, adenosine deaminase, hyaluronidase, and neuropeptide precursors. The amphipathic, alpha-helical ampulexins are among the most abundant venom components. Also prominent are members of the Toll/NF-kappaB signaling pathway, including proteases Persephone, Snake, Easter, and the Toll receptor ligand Spatzle. We find evidence that venom components are processed following envenomation. The acidic (pH~4) venom contains unprocessed neuropeptide tachykinin and corazonin precursors and is conspicuously devoid of the corresponding processed, biologically active peptides. Neutralization of venom leads to appearance of mature tachykinin and corazonin, suggesting that the wasp employs precursors as a prolonged time-release strategy within the host brain post-envenomation. Injection of fully processed tachykinin into host cephalic ganglia elicits short-term hypokinesia. Ion channel modifiers and cytolytic toxins are absent in A. compressa venom, which appears to hijack control of the host brain by introducing a "storm" of its own neurochemicals. Our findings deepen understanding of the chemical warfare underlying host-parasitoid interactions and in particular neuromodulatory mechanisms that enable manipulation of host behavior to suit the nutritional needs of opportunistic parasitoid progeny.

The genome has been available for over 10 years and has undergone several rounds of annotation. We created a comprehensive database of transcripts from 29 public RNA sequencing datasets, officially predicted genes from Ensembl plants, and common contaminants in which to search for protein-level evidence. We re-analysed nine publicly accessible rice proteomics datasets. In total, we identified 420K peptide spectrum matches from 47K peptides and 8,187 protein groups. 4168 peptides were initially classed as putative novel peptides (not matching official genes). Following a strict filtration scheme to rule out other possible explanations, we discovered 1,584 high confidence novel peptides. The novel peptides were clustered into 692 genomic loci where our results suggest annotation improvements. 80% of the novel peptides had an ortholog match in the curated protein sequence set from at least one other plant species. For the peptides clustering in intergenic regions (and thus potentially new genes), 101 loci were identified, for which 43 had a high-confidence hit for a protein domain. Our results can be displayed as tracks on the Ensembl genome or other browsers supporting Track Hubs, to support re-annotation of the rice genome. PMID- 30293065 TI - Cholesteryl Ester Transfer Protein Variant (RS1800777) with Liver Histology in Non-Alcoholic Fatty Liver Disease Patients. AB - INTRODUCTION AND AIMS: Non-alcoholic fatty liver disease (NAFLD) is a spectrum of diseases ranging from simple steatosis without inflammation or fibrosis to nonalcoholic steatohepatitis and in the Western countries has become one of the most prevalent chronic liver diseases related to metabolic and lipid alterations. Cholesteryl ester transfer protein (CETP) participates in high density lipoprotein (HDL)-cholesterol metabolism. The aim of our study was to investigate the influence of polymorphism (rs1800777) of CETP gene on liver histological changes, biochemical parameters, and serum adipokines levels in patients with NAFLD. MATERIAL AND METHODS: A population of 90 patients with NAFLD was recruited in a cross-sectional study. A biochemical analysis (glucose, c-reactive protein, insulin, homeostasis model assessment-insulin resistance, total cholesterol, low density lipoprotein (LDL)-cholesterol, HDL-cholesterol, triglycerides blood, and adipokines (leptin, adiponectin, and resistin) was realized. Genotype of polymorphism (rs1800777) of CETP gene was studied. RESULTS: Eighty-three patients (92.2%) had the genotype GG (wild type group) and 7 patients (7.8%) had the genotype GA (n = 7) or AA (n = 0; mutant type group). Patients with A allele show significant decrease in liver biochemistry parameters - Alanine amino transferase (delta 10.1 +/- 9.9 UI/L; p = 0.01), aspartate aminotransferase activity (delta 13.3 +/- 9.5 UI/L; p = 0.02), and gammaglutamine transferase levels (delta 39 +/- 30.1 UI/L; p = 0.01). Logistic regression analysis indicated that subjects with A allele carriers were associated with a decreased risk of lobulillar inflammation (OR 0.18, 95% CI 0.04-0.95, p = 0.04) and a decreased risk of steatosis (OR 0.13, 95% CI 0.02-0.89, p = 0.04). CONCLUSIONS: A variant of the polymorphism rs1800777 of CETP gene is independently associated with the presence of steatosis and lobulillar inflammation in subjects with proven biopsy NAFLD.

While computed tomography (CT) is considered first-line imaging modality in many centres, we started using magnetic resonance imaging (MRI) more and more in the last years to detect CCVM and AP to avoid radiation in this patient group. OBJECTIVE: The aim of this retrospective study was to determine and to compare the diagnostic accuracy of CT and MRI when used to detect CCVM and/or AP. METHODS: All patients suspected to have CCVM and/or AP and examined either by CT or MRI between 2000 and 2013 in our hospital were included. Extension and type of CCVM, as well as their relationship to esophagus, trachea or bronchi were assessed and related to findings of tracheobronchoscopy, cardiac catheterization or surgery if available. RESULTS: One hundred six patients (median [range] 4 years [2 days to 66 years]) were examined by CT (n = 27) or MRI (n = 79). In 78 patients (74%), CCVM and/or AP were found with either of the imaging methods. CCVM were found in 63 subjects. Forty-six of 63 subjects had both, CCVM and AP. The presence of CCVM was always detected correctly by CT or MRI, although both techniques had a weakness detecting atretic segments directly. AP (n = 61) were correctly diagnosed in all patients not intubated for artificial ventilation by CT (n = 17) and in all but 2 patients by MRI (39 out of 41). CONCLUSIONS: MRI is sensitive to detect CCVM associated with AP equally to CT without any radiation exposure. PMID- 30293067 TI - Effect of Increased Convection Volume by Mid-Dilution Hemodiafiltration on the Subclinical Chronic Inflammation in Maintenance Hemodialysis Patients. AB - Mid-dilution hemodiafiltration (MID) is a dialytic technique that might improve systemic inflammation of patients in chronic hemodialysis (HD) by increasing substitution volumes. To verify this hypothesis, we performed a prospective cross over study comparing the effect on inflammatory biomarkers of higher convection by MID versus standard convection by post-dilution hemodiafiltration (HDF). Patients under chronic HD were therefore treated by MID and HDF by crossover design. Each treatment period lasted 4 months, with 1 month of wash-out where patients were treated by HD, for a total of 9 months. Primary outcome was the change of serum pre-dialytic C-Reactive Protein (CRP), interleukin 6 (IL-6), IL 1, IL-10, transforming growth factor-beta (TGF-beta), tumor necrosis factor alpha, albumin and pre-albumin. Samples were obtained monthly. Ten HD patients were enrolled (age: 64.9 +/- 12.6 years; 70% males; dialytic vintage: 10.6 [2.7 16.2] years). Mean convection volume was 40.1 +/- 2.5 L/session in MID and 20.1 +/- 2.6 L/session in HDF. A significant reduction of beta2-Microglobulin was detected as a result of either treatment. In MID, CRP decreased from 11.3 (3.2 31.0) to 3.1 (1.4-14.4) mg/L (p = 0.007), IL-6 from 12.7 (5.0-29.7) to 8.3 (4.4 14.0) pg/mL (p = 0.003), and TGF-beta from 10.6 (7.4-15.6) to 7.4 (5.9-9.3) ng/mL (p = 0.001). A significant reduction of CRP from 8.5 (3.2-31.0) to 4.6 (3.2-31.0) mg/L was also detected in HDF (p = 0.037), whereas no significant reduction of IL 6 (p = 0.147) and TGF-beta (p = 0.094) was found. Percentage reduction of IL-6 correlated with mean convective volume in HDF (R = 0.666; p = 0.036) and in MID (R = 0.760; p = 0.020). Therefore, MID and HDF are associated with an attenuation of inflammatory pattern that is correlated with a high convective volume. PMID- 30293068 TI - Relation of the Ankle Brachial Index to Left Ventricular Ejection Fraction in Patients Without Coronary Artery Disease. AB - BACKGROUND: The low ankle brachial index (ABI) values are indicative of peripheral arterial disease, but have recently been found to be associated with reduced left ventricular ejection fraction (LVEF). This may relate to coexisting coronary artery disease (CAD). AIM: This study prospectively assessed a potential ABI-LVEF association in patients without CAD. METHODS AND RESULTS: We studied 55 patients (age 57 +/- 13 years, 49% male) with normal coronary arteries with LVEF determination. ABI, pulse wave velocity (PWV), and augmentation index (AI) were performed after coronary angiography. ABI correlated with LVEF (r = 0.40, p = 0.002), but not with PWV or AI. On linear regression analysis, ABI was independently associated with LVEF (B = 0.42, p = 0.004). The median LVEF was lower in subjects with low ABI values compared to those with normal ABI values (33 vs. 61%; p = 0.001). CONCLUSION: ABI may be influenced by LVEF independently of CAD, arterial stiffness or pressure wave reflection. PMID- 30293069 TI - Abstracts 18th ESASO Retina Academy.

AB - BACKGROUND: After undergoing a procedure of pulmonary endarterectomy (PEA), patients with chronic thromboembolic pulmonary hypertension (CTEPH) may still experience reduced exercise capacity. Data on effects of exercise training in these patients are scant. OBJECTIVES: To evaluate the effectiveness of exercise training after PEA for CTEPH and if the presence of "residual pulmonary hypertension" may affect the outcome. METHODS: Retrospective data analysis of CTEPH patients undergoing inpatient exercise training after PEA. According to predefined criteria, patients were divided into those with (group 1) and without (group 2) a "good" post-surgery hemodynamic response. Assessments of the 6-min walking distance test (6-min walking distance test [6 MWT]: primary outcome) were performed before and after surgery (before training), after training and at 3 month follow-up. Hemodynamic and lung function data were also analyzed. RESULTS: Data of 84 and 26 patients of groups 1 and 2, respectively, were analyzed. After surgery patients showed a reduction in 6 MWT, which significantly reversed after training and further improved at 3 months (p = 0.0001), without any significant difference between groups. The percentage of patients reaching the minimal clinically important difference in 6 MWT was similar between groups. The sig-nificant (p = 0.0001) post-surgery improvement in hemodynamics was maintained at 3 months without any significant difference between groups. New York Heart Association functional class improved in parallel to the hemodynamic improvement. CONCLUSIONS: Exercise training in patients with CTEPH after PEA, an inpatient exercise training program, improves exercise capacity for up to 3 months, independently of the post-surgery hemodynamic response. PMID- 30293072 TI - Clinical and Sonographic Model to Predict Cesarean Delivery after Induction of Labor at Term. AB - OBJECTIVE: To develop a model combining clinical and sonographic features to predict the risk of cesarean delivery after the induction of labor (IOL). METHODS: We designed a prospective observational study involving women admitted for IOL. The main outcome was defined as cesarean delivery due to failed IOL or arrest of labor. Several clinical and ultrasonographic variables were collected. Seventy percent of the sample was used to build the predictive model, using stepwise logistic regression, while the remaining sample was used for validation. The final model was estimated and calibrated using all participants. RESULTS: We analyzed 477 pregnancies. The main outcome occurred in 102/477 (21.4%) women. The final model included previous vaginal delivery (odds ratio [OR] 0.088; 95% confidence interval [CI] 0.04-0.21), height (OR 0.904; 95% CI 0.87-0.94), body mass index before delivery (OR 1.084; 95% CI 1.02-1.15), ultrasonographic estimated fetal weight (OR 3.965; 95% CI 2.18-7.22), and ultrasonographic cervical length (OR 1.065; 95% CI 1.04-1.09) as predictors. Area under the receiver operating characteristics curve was 0.826 (95% CI 0.78-0.87). For a 5% false-positive rate, the sensitivity, specificity, and positive and negative likelihood ratios were 44.1%, 94.9%, 8.7, and 0.59, respectively. CONCLUSION: Our model combining clinical and ultrasonographic features might offer individualized counseling regarding risk of cesarean delivery to women who are candidates for IOL. PMID- 30293073 TI - Success Rates for Retinal Detachment Repair in Alberta: A Physician Learning Program Initiative. AB - OBJECTIVE: To identify primary surgical success rates for retinal detachment repair in Alberta and compare functional outcomes of methods of repair. METHODS: Data was retrospectively extracted from the Alberta Health Services Discharge Abstract Database and the National Ambulatory Care Reporting System for all patients diagnosed with retinal detachment and vitreoretinal procedures during the 2008/09 to 2012/13 fiscal years. RESULTS: Of the 5,433 surgeries for retinal detachment identified, 279 were excluded due to invalid provincial health numbers, unidentified procedure location, and/or treating physician other than an Alberta retina surgeon. The final analysis included 4,336 detachments in 4,020 patients. The average primary retinal detachment success rate was 84.9% (3,680/4,336). Primary success rates varied between vitrectomy only (84.9%, 2,149/2,532), vitrectomy and scleral buckle (85.5%, 818/957), and scleral buckle (84.4%, 702/832). CONCLUSIONS: Alberta retina surgeons have an average primary success rate of 84.9% (3,680/4,336) for repair of retinal detachments. This result is in keeping with other published retinal detachment success rate studies. PMID- 30293074 TI - Health-Related Quality of Life in Patients with Small Intestine Neuroendocrine Tumours. AB - BACKGROUND: The prevalence of small intestine neuroendocrine tumours (SI-NETs) is increasing. Disease progression is often slow and treatment options and long-term survival rates have improved, but little is known about health-related quality of life (HRQoL) in these patients.
Objective: To assess HRQoL and its predictors in SI-NET patients receiving contemporary treatments.
Methods: We measured HRQoL with 15D and SF-36 questionnaires in 134 SI-NET patients and compared the 15D results to those of age- and gender-standardized general population (n = 1153). In the patients, we studied impact of treatments, Ki67, liver metastases, circulating tumour markers, comorbidities and/or socioeconomic factors on HRQoL with linear regression analysis.
Results: Mean disease duration of the patients was 81 (4-468) months, 91% had metastatic disease and 79% received somatostatin analog treatment. Hepatic tumour load was 0% in 44.8%, <10-25% in 44.0%, and >25% in 11.2%, respectively. Mean fP-CgA and S-5HIAA concentrations were 15 (1.3-250) nmol/l and 344 (24-7470) nmol/l, respectively. Overall HRQoL was significantly impaired in patients compared to controls (15D scores 0.864+/ 0.105 vs 0.905+/-0.028, p<0.001). SI-NET patients scored worse on 9 of 15 dimensions (sleep, excretion (ie bladder and bowel function), depression, distress, vitality, sexual activity (p< 0.001), breathing, usual activities, and discomfort and symptoms (p< 0.01-0.05). SF-36 scores were impaired and highly correlated with 15D scores (p<0.001). HRQoL was impaired in patients with (n=85) compared to patients without (n=49) impaired excretion (0.828 vs 0.933, p<0.001). In the patient group, number of medications predicted impaired HRQoL.
Conclusions: Despite contemporary treatments, SI-NET patients have severely impaired HRQoL, including diarrhea, sleep, depression, vitality and sexual activity.
. PMID- 30293075 TI - Different Chemotherapy Regimens in the Management of Advanced or Metastatic Urothelial Cancer: a Bayesian Network Meta-Analysis of Randomized Controlled Trials. AB - BACKGROUND/AIMS: Urothelial cancer (UC) as a chemotherapy-sensitive tumor, has achieved remarkable progresses in therapeutic paradigm, particularly in the advanced/metastatic stages. However, both clinicians and patients are confused when it comes to choosing the optimal chemotherapy. Hence, this article was aimed to conduct a comprehensive comparison of different chemotherapy regimens for advanced or metastatic UC in terms of survival benefits or adverse events. METHODS: The online databases PubMed, EMBASE and Web of Science were searched systematically and comprehensively for randomized controlled trials (RCTs) up to September 15, 2017. The pooled hazard ratios (HRs) or odds ratios (ORs) with 95% credible interval (CrI) were calculated by Markov chain Monte Carlo methods. The effectiveness and safety of included regimens were conducted to provide a hierarchy by means of rank probabilities with the help of "R-3.4.0" software and the "gemtc-0.8.2" package. The surface under the cumulative ranking curve (SUCRA) was also incorporated in our analysis for ranking the corresponding chemotherapy regimens. RESULTS: Ten different chemotherapy regimens involved in this article were predominantly of trials in a first-line setting, and eight clinical outcomes were ultimately analyzed in this study. In terms of Overall response rate (ORR), Overall survival (OS) or Progression-free survival (PFS)/Time to progression (TTP), the rank probabilities and SUCRA indicated that Paclitaxel/cisplatin/gemcitabine (PCG) was superior to gemcitabine/cisplatin (GC) or methotrexate/vinblastine/doxorubicin/cisplatin (MVAC), the traditional first line treatment for advanced/metastatic UC. In the case of ORR or PFS/TTP, GC+sorafenib also displayed its superiority in comparison with GC or MVAC. Despite their survival benefits, PCG or GC+sorafenib presented a relatively higher incidence of adverse events. CONCLUSION: Our results revealed that by adding a paclitaxel or sorafenib into the first-line GC, it could yield a better survival benefit, but also worsen adverse events for advanced/ metastatic UC. Clinically, physicians should weigh the merits of these approaches to maximize the survival benefits of eligible patients. PMID- 30293076 TI - Surfactant Proteins A and D: Trimerized Innate Immunity Proteins with an Affinity for Viral Fusion Proteins. AB - Innate recognition of viruses is an essential part of the immune response to viral pathogens. This is integral to the maintenance of healthy lungs, which are free from infection and efficient at gaseous exchange. An important component of innate immunity for identifying viruses is the family of C-type collagen containing lectins, also known as collectins. These secreted, soluble proteins are pattern recognition receptors (PRRs) which recognise pathogen-associated molecular patterns (PAMPs), including viral glycoproteins. These innate immune proteins are composed of trimerized units which oligomerise into higher-order structures and facilitate the clearance of viral pathogens through multiple mechanisms. Similarly, many viral surface proteins form trimeric configurations, despite not showing primary protein sequence similarities across the virus classes and families to which they belong. In this review, we discuss the role of the lung collectins, i.e., surfactant proteins A and D (SP-A and SP-D) in viral recognition. We focus particularly on the structural similarity and complementarity of these trimeric collectins with the trimeric viral fusion proteins with which, we hypothesise, they have elegantly co-evolved. Recombinant versions of these innate immune proteins may have therapeutic potential in a range of infectious and inflammatory lung diseases including anti-viral therapeutics. PMID- 30293077 TI - Difference in Stroke Knowledge between Rural and Urban Communities in a Developing Country after Community-Based Stroke Educational Campaigns: Results from a Cross-Sectional Study. AB - BACKGROUND: Ischemic stroke is a leading cause of disability and death in Mexico. Poor ability to identify signs and symptoms of ischemic stroke leads to longer hospital arrival times and precludes prompt treatment. The knowledge of stroke risk factors and warning signs in rural population is scarce. Since 2010, Stroke Education Campaigns are performed with a community-based approach. The aim of this study was to assess and compare stroke knowledge in rural and urban communities. METHODS: During World Stroke Campaign, a standardized questionnaire to assess knowledge of stroke risk factors and warning signs was applied in urban and non-urban communities of Nuevo Leon, Mexico. RESULTS: A total of 4,144 surveys were collected. Mean age was 44.2 +/- 16.1 and 75.9% were women. People from rural and semi-urban areas mentioned > 3 risk factors (p < 0.001) and warning signs (p < 0.001) compared to the urban area. After logistic regression analysis, having received previous information about stroke remained significant for the knowledge of > 3 stroke risk factors and warning signs (p < 0.001; 95% CI 1.997-2.727; p < 0.001; 95% CI 1.880-3.787) respectively. CONCLUSIONS: Rural and semi-urban regions performed better than the urban population. Receiving stroke information is a determinant factor for stroke knowledge. Stroke Educational Campaigns are a cost-effective method for raising stroke awareness, thus reducing stroke burden. PMID- 30293078 TI - Functional Outcome and Quality of Life after Ileal Pouch-Anal Anastomosis within a Defined Population in Sweden. AB - OBJECTIVE: The purpose of this population-based study was to present prospectively recorded functional data and health-related quality of life (HRQOL) questionnaire data to assess the long-term results of the first 100 consecutive ileal pouch-anal anastomosis (IPAA) performed chronologically by 3 surgeons in a single referral centre. METHODS: During 1993-2008, 100 patients underwent IPAA. The 90 patients still alive with an intact pouch were included (response rate = 92%). Function was evaluated using St Mark's incontinence score, and HRQOL with SF-36. RESULTS: At 18 months after loop ileostomy closure, 63 patients (76%) had 4-6 day-time and 47 patients (57%) had no night-time bowel movements. A stapled IPAA resulted in better St Mark's (p = 0.0064) and Wexner scores (p = 0.0019) than did a hand-sewn anastomosis. The younger the patients were at the onset of ulcerative colitis (UC) the better St Mark's (p = 0.0037) and Wexner scores (p = 0.011) were. The patients scored significantly higher than did the general Swedish population adjusted by age-group and sex in 6 out of 7 SF-36 subscales. CONCLUSIONS: In the hands of experienced high-volume surgeons, IPAA is a safe procedure associated with good functional results that are stable over time. Stapled IPAA and younger age at onset of UC were correlated with better functional results. The HRQOL scores were high. PMID- 30293079 TI - Investigation of Therapeutic Effects of Erdosteine on Polycystic Ovary Syndrome in a Rat Model. AB - OBJECTIVE: Polycystic ovary syndrome (PCOS) is a serious endocrine disorder. In the present study, we investigated the therapeutic effects of erdosteine in letrozole induced-PCOS in rats.

Methods: Thirty two wistar albino female rats were grouped as control group (C), PCOS group (PCOS), PCOS-metformin group (PCOS+MET), PCOS-erdosteine group (PCOS+Erd). Polycystic ovary syndrome was induced by administering letrozole; such rats presented with sex hormone disorder, abnormal estrous cycles determined by daily vaginal smear, large cystic follicles, and increasing fasting insulin levels. After induction of PCOS, Metformin (500 mg/kg/day) and Erdostein (100 mg/kg/day) were given orally to the treatment groups for 30 days. Serum concentrations of glucose, total cholesterol, low- and high-density lipoprotein, triglyceride, as well as the total oxidant and antioxidant status, oxidative stress index, circulating estrone (E1), estradiol (E2), testosterone, androstenedione were evaluated. The ovaries were graded histologically. RESULTS: Weights of ovarian tissues (p < 0.05) and the number of atretic follicles (p < 0.001) and cystic follicles (p < 0.01) decreased in PCOS+Erd group; the corpus luteum number was significantly higher in PCOS+Erd group (p < 0.01) as compared with PCOS group. Lipid parameters (Total-C, LDL-C and TG), E1 (Estrone), E1/E2 ratio, testosterone and androstenedione significantly decreased, while HDL-C, E2 (Estradiol) significantly increased in PCOS+Erd group as compared with PCOS group. Moreover glucose, insulin and HOMA-IR were reduced with treatment of Erdosteine (p > 0.05, p < 0.001, p < 0.001 respectively). CONCLUSION: It is suggested that Erdosteine may be used in treatment of PCOS as an alternative to metformin. It appears that our findings might be supported by clinical and molecular studies.

. PMID- 30293080 TI - Epirubicin is More Effective than Miriplatin in Balloon-Occluded Transcatheter Arterial Chemoembolization for Hepatocellular Carcinoma. AB - BACKGROUND: Transcatheter arterial chemoembolization (TACE) is a standard therapy used in the treatment of intermediate hepatocellular carcinoma (HCC). Recently, balloon-occluded TACE (B-TACE) has been developed. PURPOSE: This study aimed to clarify the effects of B-TACE in patients with HCC, with a focus on which drug is suitable to suspend in Lipiodol for B-TACE. METHODS: We retrospectively evaluated 35 patients with HCC treated with B-TACE. Factors associated with enhanced time to progression (TTP) after B-TACE were evaluated using univariate and multivariate analyses. RESULTS: A total of 35 patients with HCC (40 nodules) were treated with B-TACE between June 2013 and August 2016. Epirubicin was used in 25 nodules and miriplatin was used in 15 nodules. Epirubicin (15.1 months) was significantly better than miriplatin (3.2 months) in prolonging the local TTP after B-TACE (p = 0.0293). Epirubicin showed a positive tendency in TE4 (100% tumor necrosis) rate when compared with miriplatin (p = 0.058). Achievement of TE4 was the only significant factor associated with better TTP after B-TACE. Epirubicin- and TACE-naive statuses were significant factors in achieving TE4 with B-TACE. CONCLUSION: To enhance the TTP with B-TACE, TE4 should be achieved. Epirubicin is a more optimal anticancer drug (as a Lipiodol suspension) than miriplatin for achieving TE4 with B-TACE. PMID- 30293081 TI - High-Salt Diet Gets Involved in Gastrointestinal Diseases through the Reshaping of Gastroenterological Milieu. AB - BACKGROUND: Gastrointestinal (GI) diseases are known to be largely influenced by one's lifestyle and dietary uptake. A high-salt diet (HSD) is well recognized as a risk factor for cardiovascular complications, hypertension, and metabolic syndromes. However, the relationship between an HSD and the GI system, which is the compartment that comes in direct contact with exogenous stimulants, has not been fully explored. AIMS: We seek to better understand the complexity of the pathogenic effects of an HSD in the context of GI disorders. METHODS: By searching the PubMed and Web of science, the review of literature was performed using keywords: high-salt and GI, high-salt and immunity, salt and microbiota, salt and hormone. RESULTS: In this review, we concluded that high-salt intake potentially perturbs the local immune homeostasis, alters the gut microbiota composition and function, and affects the endocrine hormone profiling in the GI system. CONCLUSION: HSD might get involved in GI diseases through the reshaping of gastroenterological milieu, which could help to better understand the complexity of the pathogenic effects of an HSD in the context of GI disorders. PMID- 30293082 TI - The Effect of Autoantibody against M2-Muscarinic Acetylcholine Receptor in Heart Failure Patients on Digoxin Treatment. AB - BACKGROUND: Autoantibody against M2-muscarinic acetylcholine receptor (anti M2AChR) has a biological effect similar to a vagus agonist. Digoxin has a function of vagus nervous system stimulation. We hypothesized that anti-M2AChR is highly correlated with digoxin in patients with chronic heart failure (CHF). METHODS: Synthetic M2AChR peptides served as the target antigen in an ELISA were used to screen the sera of 80 CHF patients, who were separated into a negative ( ) or positive (+) anti-M2AChR group according to their anti-M2AChR reactivity. Echocardiography and serum digoxin concentration (SDC) were performed at baseline and after 1 year of digoxin in combination with the standard treatment regime. The end-point events were compared over 1 year of follow-up. RESULTS: Seventy-two CHF patients completed the final data analysis, including 32 (+)anti-M2AChR and 40 (-)anti-M2AChR patients. The resting heart rate of the positive group was higher than that of the negative group at baseline (p < 0.05; 89.0 +/- 1.6 vs. 83.8 +/- 1.1 bpm). Both groups showed improvement in the left ventricular end diastolic and end-systolic dimensions and ejection fraction with digoxin in combination with the standard treatment regime for 1 year (all p < 0.01). However, the 32 patients with (-)anti-M2AChR had greater improvements than the 40 patients with (+)anti-M2AChR, and this was accompanied by a marked decrease of rehospitalization (all p < 0.01) but not of cardiovascular mortality after 1 year. The SDC of patients with (-)anti-M2AChR was significantly lower than that of patients with (+)anti-M2AChR (p < 0.05; 0.63 +/- 0.05 vs.1.16 +/- 0.06 ng/mL) and had a positive correlation with anti-M2AChR (r = 0.81, p < 0.001). CONCLUSION: These results suggested that anti-M2AChR could be a useful biomarker of vagus nerve overactivation and is associated with a poor response to digoxin treatment in CHF patients. PMID- 30293083 TI - Gambogic Acid Induces Apoptosis of Non-Small Cell Lung Cancer (NSCLC) Cells by Suppressing Notch Signaling. AB - BACKGROUND Activation of Notch signaling was found to be associated with cancer. Gambogic acid (GA) was reported to be an anti-cancer agent. This study investigated the anti-cancer effect of GA on human non-small cell lung cancer (NSCLC) cells. Involvement of the Notch pathway was also studied. MATERIAL AND METHODS GA at 0, 0.5, 0.75, and 1.0 MUmol/l was used to incubate A549 and SPC-A1 cells. MTT assay was used to determine the cell viability. TUNEL assay was used to detect the apoptosis. Western blotting was used to evaluate protein expression levels, protein phosphorylation levels, and nuclear translocation levels. RESULTS Notch signaling pathway was activated in NSCLC cells. GA treatment significantly inhibited NSCLC cell viability and increased cell apoptosis. GA treatment significantly decreased the expression levels of DLL1, DLL3, DLL4, Jagged1, Jagged2, Bcl2, and PK3K, inhibited NICD nuclear translocation and Akt phosphorylation, and increased expression level of active caspase3. CONCLUSIONS GA inhibited NSCLC cell viability by inducing apoptosis. Inhibition of the Notch signaling pathway was the mechanism involved in the anti-proliferation effect of GA on NSCLC. PMID- 30293084 TI - Toll-Like Receptor 4 (TLR-4) Pathway Promotes Pulmonary Inflammation in Chronic Intermittent Hypoxia-Induced Obstructive Sleep Apnea. AB - BACKGROUND Studies have shown that intermittent hypoxia mimics obstructive sleep apnea in causing pulmonary inflammation, but the mechanism is not yet clear.TLR-4 is a recognized proinflammatory factor, so the purpose of this study was to assess the function of TLR-4 in pulmonary inflammation induced by chronic intermittent hypoxia simulating obstructive sleep apnea. MATERIAL AND METHODS Healthy male Wistar rats were divided into 3 groups (8 in each group): the normoxia control group (CG), the intermittent hypoxia group (IH), and the TLR4 antagonist TAK242 treatment group (3 mg/kg, daily), with exposure durations of 12 weeks and 16 weeks (HI). The morphological changes of lung tissue were determined with hematoxylin-eosin (HE) staining. The expressions of the TLR-4 pathway in lung tissue were tested by Western blotting and RT-PCR. The levels of IL-6 and TNF-a in serum and lung tissue were detected by enzyme-linked immunosorbent assay (ELISA). The levels of SOD and MDA in lung tissue were detected by use of SOD and MDA kits, respectively. RESULTS After TAK242 treatment, damage to lung tissue was increased, and the expressions of TLR-4, MYD88, P65, IL-6, TNF-alpha, MDA, and SOD were decreased. Intermittent hypoxic exposure caused alveolar expansion, thickening of alveolar septum, and fusion of adjacent alveoli into larger cysts under intermittent hypoxia in a time-dependent manner. Compared with the CG and HI groups, the mean lining interval (MLI) become more thickened and the alveolar destruction index (DI) increased significantly in the IH group. CONCLUSIONS Chronic intermittent hypoxia causes pulmonary inflammatory response and the inflammatory pathway involved in TLR4 receptor may be one of the mechanisms that trigger lung inflammation.

AB - BACKGROUND Accumulating studies demonstrate that microRNAs play crucial roles in multiple processes of cancer progression. Lower levels of miR-183 have been observed in diverse types of tumors but the mechanism and precise function of miR 183-5p in cervical cancer have largely not been investigated. MATERIAL AND METHODS The level of miR-183-5p in different cervical cancer cell lines and clinical tissues was detected qRT-PCR assays. Transwell and wound-healing migration assays were conducted to assess the functional roles of miR-183-5p in over-expressing cervical cancer cells in vitro. Rescue assays were carried out to confirm the contribution of integrin subunit Beta 1 (ITGB1) to the aggressiveness of cancer cells regulated by miR-183-5p. RESULTS miR-183-5p was reduced in clinical tissues of cervical cancer and cell lines when compared to the normal subjects and normal cervical epithelial cell line, respectively. In addition, over-expression of miR-183-5p markedly inhibited migration and invasion in cervical cancer cells, and increased aggressiveness was observed in miR-183-5p inhibitor transfected cells. Furthermore, the luciferase reporter assays revealed that ITGB1 was the gene directly regulated by miR-183-5p. Notably, a negative association between the ITGB1 and miR-183-5p was found, and the gene expressions of ITGB1 was mediated by miR-183-5p in cervical cancer cells. CONCLUSIONS miR-183 5p serves as a latent anti-oncogene by targeting the metastasis-promoter gene, ITGB1. PMID- 30293087 TI - Relapse to opioid seeking in rat models: behavior, pharmacology and circuits. AB - Lifetime relapse rates remain a major obstacle in addressing the current opioid crisis. Relapse to opioid use can be modeled in rodent studies where drug self administration is followed by a period of abstinence and a subsequent test for drug seeking. Abstinence can be achieved through extinction training, forced abstinence, or voluntary abstinence. Voluntary abstinence can be accomplished by introducing adverse consequences of continued drug self-administration (e.g., punishment or electric barrier) or by introducing an alternative nondrug reward in a discrete choice procedure (drug versus palatable food or social interaction). In this review, we first discuss pharmacological and circuit mechanisms of opioid seeking, as assessed in the classical extinction reinstatement model, where reinstatement is induced by reexposure to the self administered drug (drug priming), discrete cues, discriminative cues, drug associated contexts, different forms of stress, or withdrawal states. Next, we discuss pharmacological and circuit mechanisms of relapse after forced or voluntary abstinence, including the phenomenon of "incubation of heroin craving" (the time-dependent increases in heroin seeking during abstinence). We conclude by discussing future directions of preclinical relapse-related studies using opioid drugs. PMID- 30293088 TI - The COSMIC Cancer Gene Census: describing genetic dysfunction across all human cancers. AB - The Catalogue of Somatic Mutations in Cancer (COSMIC) Cancer Gene Census (CGC) is an expert-curated description of the genes driving human cancer that is used as a standard in cancer genetics across basic research, medical reporting and pharmaceutical development. After a major expansion and complete re-evaluation, the 2018 CGC describes in detail the effect of 719 cancer-driving genes. The recent expansion includes functional and mechanistic descriptions of how each gene contributes to disease generation in terms of the key cancer hallmarks and the impact of mutations on gene and protein function. These functional characteristics depict the extraordinary complexity of cancer biology and suggest multiple cancer-related functions for many genes, which are often highly tissue dependent or tumour stage-dependent. The 2018 CGC encompasses a second tier, describing an expanding list of genes (currently 145) from more recent cancer studies that show supportive but less detailed indications of a role in cancer. PMID- 30293089 TI - Sex differences in mortality after heat waves: are elderly women at higher risk? AB - BACKGROUND AND OBJECTIVE: Climate change leads to more frequent, intense and longer-lasting heat waves which can have severe health outcomes. The elderly are a high-risk population for heat-related mortality and some studies suggested that elderly women are more affected by extreme heat than men. This study aimed to review the presence of sex-specific results in studies performed on mortality in elderly (> 65 years old) after heat waves in Europe. METHODS: A literature search was conducted in July 2017 on papers published in databases Pubmed and Web of Science between January 2000 and December 2016. RESULTS: 68 papers that included mortality data for elderly after heat waves were identified. The 13 of them which presented results distinguished by sex and age group were included in the review. Eight studies showed worse health outcome for elderly women compared to men. One study showed higher mortality rates for men, two found no sex differences and two studies presented inconsistent results. CONCLUSION: Studies that present sex stratified data on mortality after heat waves seem to indicate that elderly women are at higher risk than men. Future research is warranted to validate this finding. Furthermore, a better understanding on the underlying physiological or social mechanisms for possible sex and gender differences in excessive deaths for this vulnerable population is needed to set up appropriate policy measures. PMID- 30293091 TI - The internal nasal valve: a validated grading system and operative guide. AB - PURPOSE: Nasal obstruction is a highly subjective and commonly reported symptom. The internal nasal valve (INV) is the rate limiting step to nasal airflow. A static INV grading score was devised with regard to visibility of the middle turbinate. METHODS: A prospective study of all patients who underwent primary external functional septorhinoplasty in 2017 for nasal obstruction. All patients' INV score was assessed pre- and postoperatively in a blinded and independent fashion by surgeons of varying seniority. RESULTS: Twenty-eight patients were studied, with mean age 30.9 years and follow-up 18.8 weeks. Inter-rater and test retest reliability of INV grading were excellent, with Cronbach's alpha 0.936 and 0.920, respectively. There was also statistically significant improvement in both subjective and objective postoperative outcome measures including nasal inspiratory peak flows. CONCLUSIONS: We demonstrate a novel, easy to interpret, clinically valuable grading system of the static internal nasal valve that is reliable and reproducible.

AB - Giant-Skippers (Megathymini) are unusual thick-bodied, moth-like butterflies whose caterpillars feed inside Yucca roots and Agave leaves. Giant-Skippers are attributed to the subfamily Hesperiinae and they are endemic to southern and mostly desert regions of the North American continent. To shed light on the genotypic determinants of their unusual phenotypic traits, we sequenced and annotated a draft genome of the largest Giant-Skipper species, the Bear (Megathymus ursus violae). The Bear skipper genome is the least heterozygous among sequenced Lepidoptera genomes, possibly due to much smaller population size and extensive inbreeding. Their lower heterozygosity helped us to obtain a high quality genome with an N50 of 4.2 Mbp. The ~ 430 Mb genome encodes about 14000 proteins. Phylogenetic analysis supports placement of Giant-Skippers with Grass Skippers (Hesperiinae). We find that proteins involved in odorant and taste sensing as well as in oxidative reactions have diverged significantly in Megathymus as compared to Lerema, another Grass-Skipper. In addition, the Giant Skipper has lost several odorant and gustatory receptors and possesses many fewer (1/3-1/2 of other skippers) anti-oxidative enzymes. Such differences may be related to the unusual life style of Giant-Skippers: they do not feed as adults, and their caterpillars feed inside Yuccas and Agaves, which provide a source of antioxidants such as polyphenols. PMID- 30293090 TI - Long non-coding RNA AFAP1-AS1 plays an oncogenic role in promoting cell migration in non-small cell lung cancer. AB - Long non-coding RNA (lncRNA) plays an important role in tumor progression and metastasis. Emerging evidence indicates that lncRNA actin filament-associated protein 1-antisense RNA 1 (AFAP1-AS1) is dysregulated in certain tumors. However, the function of AFAP1-AS1 in non-small cell lung cancer (NSCLC) remains elusive. In this study, we conducted global lncRNA profiling and identified that AFAP1-AS1 is significantly upregulated in NSCLC, suggesting that AFAP1-AS1 may be important for lung cancer development. For the first time, the transcription initiation and termination sites of AFAP1-AS1 were identified by rapid amplification of cDNA ends technology, and the sequencing data indicated that AFAP1-AS1 in lung cancer cells is a novel transcript variant. Through gain- and loss-of-function studies, AFAP1-AS1 was demonstrated to promote cell migration and invasion. Mechanistically, AFAP1-AS1 functions through positively regulating the expression of AFAP1 protein. On the other hand, the expression of lncRNA AFAP1-AS1 negatively correlates with CpG methylation status of its gene promoter, identified in both lung cancer cells and patient tissues, and treatment with DNA methyltransferase inhibitor decitabine significantly activates AFAP1-AS1 expression, strongly supporting that AFAP1-AS1 expression is tightly regulated by DNA methylation. Taken together, this study demonstrates that AFAP1-AS1 acts as an oncogene in NSCLC to promote cell migration partly by upregulating AFAP1 expression, while its own expression is controlled by DNA methylation, and highlights its diagnostic and therapeutic values for NSCLC patients. PMID- 30293093 TI - Peer support opportunities across the cancer care continuum: a systematic scoping review of recent peer-reviewed literature. AB - OBJECTIVE: Evidence suggests peer support (PS) is as an effective strategy for enhancing prevention and control of chronic and infectious diseases, including cancer. This systematic scoping review examines the range and variety of interventions on the use of PS across the cancer care continuum. METHOD: We used a broad definition of PS to capture a wide-range of interventions and characterize the current status of the field. Literature searches were conducted using PubMed, SCOPUS, and CINAHL to identify relevant articles published from January 2011 to June 2016. We screened the title and abstracts of 2087 articles, followed by full-text screening of 420 articles, resulting in a final sample of 242 articles of which the most recent 100 articles were reviewed (published June 2014 to May 2016). RESULTS: A number of the recent intervention studies focused on breast cancer (32%, breast cancer only) or multiple cancer sites (23%). Although the interventions spanned all phases of the cancer care continuum, only 2% targeted end-of-life care. Seventy-six percent focused on clinical outcomes (e.g., screening, treatment adherence) and 72% on reducing health disparities. Interventions were primarily phone-based (44%) or delivered in a clinic setting (44%). Only a few studies (22%) described the impact of providing PS on peer supporters. CONCLUSION: PS appears to be a widely used approach to address needs across the cancer care continuum, with many opportunities to expand its reach. PMID- 30293095 TI - Prevalence and predictors of atrial arrhythmias in patients with sinus node dysfunction and atrial pacing. AB - PURPOSE: This study aimed to determine the incidence, prevalence, and predictors of atrial arrhythmias (AAs) in patients with symptomatic sinus node dysfunction (SND) who required permanent pacemaker implantation. Also, we evaluated the impact of atrial pacing (AP) on AAs. METHODS: All consecutive patients who underwent pacemaker implantation from 2005 to 2011 were included. Atrial fibrillation (AF), atrial flutter (AFL), atrial tachycardia (AT), and AV nodal reentrant tachycardia (AVNRT) were detected via pacemaker interrogation and clinical documentation. RESULTS: The study group included 322 patients (44% male) with mean age 68.8 +/- 15 years and followed for an average of 5.6 +/- 2.2 years (median 5.7 years). Overall, 61.8% were found to have any AA at follow-up. Individual prevalence of AAs was high as follows: AF 43.5%, AFL 6.5%, AT 25%, and AVNRT 6.8%. AF was documented in 23% of patients (n = 74) prior to pacemaker; among those, 15% (n = 11) had no recurrence of AF with average AP of 74%. The incidence of new-onset AF after pacemaker was 15.8%. In subgroup analysis, prevalence of AF was increased by 16% with high rate of AP (81-100%) and 17% with lower rate of AP (0-20%). Incidence of new-onset AF was not affected by AP. Diabetes, hypertension, and left atrial enlargement were predictors of AAs. White men and women had higher prevalence of AF. CONCLUSIONS: AAs are highly prevalent in SND, particularly in white patients. Paroxysmal AF is suppressed with AP in minority, but there is no impact of AP on new-onset AF. Patients with diabetes, hypertension, and dilated atria must be monitored closely for early detection of AAs. PMID- 30293094 TI - The Role of Tau Imaging in Parkinsonian Disorders. AB - PURPOSE OF REVIEW: Differential diagnosis of atypical Parkinson syndromes (APS) is difficult as clinical presentations may vary and as there is a strong overlap between disease entities. Aggregations of misfolded and hyperphosphorylated tau proteins are the common denominator of many of these diseases. RECENT FINDINGS: Several tau targeting positron emission tomography (PET) tracers have been evaluated as possible biomarkers in APS in the recent years. For Parkinson's disease, dementia with Lewy bodies, progressive supranuclear palsy, and corticobasal degeneration, promising results have been reported with regard to the ability to detect the presence of disease and to discriminate patients from controls. However, the discussion about the specificity of the first-generation radiotracers and their value in the clinical context is ongoing. A combined interpretation of signal strength and distribution pattern in PET scans with first- and second-generation tracers may be helpful in clinical diagnosis and follow-up of patients with APS. PMID- 30293096 TI - Let's Open the Decision-Making Umbrella: A Framework for Conceptualizing and Assessing Features of Impaired Decision Making in Addiction. AB - Decision-making impairments play a pivotal role in the emergence and maintenance of addictive disorders. However, a sound conceptualization of decision making as an umbrella construct, encompassing its cognitive, affective, motivational, and physiological subcomponents, is still lacking. This prevents an efficient evaluation of the heterogeneity of decision-making impairments and the development of tailored treatment. This paper thus unfolds the various processes involved in decision making by adopting a critical approach of prominent dual- or triadic-process models, which postulate that decision making is influenced by the interplay of impulsive-automatic, reflective-controlled, and interoceptive processes. Our approach also focuses on social cognition processes, which play a crucial role in decision making and addictive disorders but were largely ignored in previous dual- or triadic-process models. We propose here a theoretical framework in which a range of coordinated processes are first identified on the basis of their theoretical and clinical relevance. Each selected process is then defined before reviewing available results underlining its role in addictive disorders (i.e., substance use, gambling, and gaming disorders). Laboratory tasks for measuring each process are also proposed, initiating a preliminary process based decision-making assessment battery. This original approach may offer an especially informative view of the constitutive features of decision-making impairments in addiction. As prior research has implicated these features as risk factors for the development and maintenance of addictive disorders, our processual approach sets the scene for novel and transdiagnostic experimental and applied research avenues. PMID- 30293098 TI - Burden of Migraine in Europe Using Self-Reported Digital Diary Data from the Migraine Buddy(c) Application. AB - INTRODUCTION: Migraine is a neurological disease characterized by recurring attacks that can cause severe disabling pain. This study described the burden of migraine as reported by individuals with migraine in the real world using a mobile application. METHODS: A retrospective, cross-sectional analysis was conducted using data captured through the Migraine Buddy(c) smartphone application from adult, self-diagnosed individuals with migraine in 17 European countries. Data were analyzed descriptively for the most recent 28-day period reported by users (n = 3900) during the study period (June 2015-July 2016) who were randomly selected on the basis of data completeness (completion rates > 70%) and stratified by migraine headache days/month: 4-7 episodic migraine (EM; n = 1500), 8-14 EM (n = 1500), and chronic migraine (>= 15; CM; n = 900). RESULTS: More than 95% of users reported that migraine negatively affected their daily activities during at least one migraine attack. Attacks affected 50.5% (184.4 days/year), 26.9% (98 days/year), and 14.5% (53 days/year) of the year among CM, 8-14 EM, and 4-7 EM groups, respectively. On average, 44.8% CM, 40.9% 8-14 EM, and 34.7% of 4-7 EM sufferers, respectively, reported anxiety and/or depression symptoms during migraine attacks. Social or home activities, productivity, and sleep were highly affected, regardless of migraine frequency. Employed respondents (n = 3106) reported an average of 2.3 workdays missed per month and that at least one in four migraines led to work absenteeism; these migraines were commonly reported to have at least moderate to severe levels of pain, corresponding to the inability of persons to perform some or even any activities. Triptans (68%), opioids (46%), and nonsteroidal anti-inflammatory drugs (45%) were self-reported as the most common medicines used. CONCLUSIONS: This study, leveraging patient-reported data collected through a mobile application, demonstrates the high burden and impact of migraine on health-related quality of life, work productivity, and overall well-being of individuals suffering from migraines.

AB - PURPOSE: Obstructive sleep apnea (OSA) is a common sleep disorder in Parkinson's disease (PD), but the relationship between these two conditions remains uncertain. Upper airway (UA) dysfunction in PD is well documented in some patients and is believed to be a reflex of the motor involvement of laryngopharyngeal muscles. The aim of this study is to determine whether UA dysfunction and laryngopharyngeal motor dysfunction (LMD) are involved in the obstructive phenomenon of OSA in PD. METHODS: Forty-eight PD patients underwent polysomnography for OSA diagnosis, functional evaluation of the UA by spirometry and a clinical protocol for analysis of laryngopharyngeal muscles and physical examination. RESULTS: Thirty-one participants (64.6%) fulfilled the criteria for OSA according to the International Classification of Sleep Disorders- third edition (at least respiratory disturbance index of five or higher per hour of sleep plus specific symptoms). UA obstruction was observed in 25% of participants and LMD in 60.4%. Among the clinical indicators of LMD, hypophonia was the most common (58.3%). Participants with LMD had a threefold greater chance of presenting with OSA than those without LMD did (OR = 3.49; 95% CI, 1.01-12.1; p = 0.044). Individuals with LMD had more UA dysfunction (37.9 vs 10.5%, p = 0.037), higher scores on UPDRS III (20 vs 15, p = 0.0005) and the Hoehn-Yahr scale (2.5 vs 2.0, p = 0.008), and higher frequencies of postural changes (51.7 vs 21.1%, p = 0.033) and motor phenomena (65.5 vs 31.6%, p = 0.021). Obesity, snoring, neck circumference, and the Mallampati score did not correlate with OSA in PD. CONCLUSION: LMD should be considered a factor that is involved in the obstructive phenomenon of UA in patients with OSA and PD. PMID- 30293100 TI - Spontaneous cardiac baroreflex sensitivity is enhanced during post-exercise ischemia in men but not in women. AB - PURPOSE: To investigate the effect of isolated muscle metaboreflex activation on spontaneous cardiac baroreflex sensitivity (cBRS), and to characterize the potential sex-related differences in this interaction in young healthy subjects. METHODS: 40 volunteers (20 men and 20 women, age: 22 +/- 0.4 year) were recruited. After 5-min rest period, the subjects performed 90 s of isometric handgrip exercise at 40% of maximal voluntary contraction followed by 3 min of post-exercise ischemia (PEI). Beat-to-beat heart rate and arterial blood pressure were continuously measured by finger photopletysmography. Spontaneous cBRS was assessed using the sequence technique and heart rate variability was measured in time (RMSSD-standard deviation of the RR intervals) and frequency domains (LF-low and HF-high frequency power). RESULTS: Resting cBRS was similar between men and women. During PEI, cBRS was increased in men (Delta3.0 +/- 1.1 ms mmHg- 1, P = 0.03) but was unchanged in women (Delta-0.04 +/- 1.0 ms mmHg- 1, P = 0.97). In addition, RMSSD and HF power of heart rate variability increased in women (Delta7.4 +/- 2.6 ms, P = 0.02; Delta373.4 +/- 197.3 ms2; P = 0.04, respectively) and further increased in men (Delta26.4 +/- 7.1 ms, P < 0.01; Delta1874.9 +/- 756.2 ms2; P = 0.02, respectively). Arterial blood pressure increased from rest during handgrip exercise and remained elevated during PEI in both groups, however, these responses were attenuated in women. CONCLUSIONS: These findings allow us to suggest a sex-related difference in spontaneous cBRS elicited by isolated muscle metaboreflex activation in healthy humans. PMID- 30293097 TI - Suicide Risk and the Menstrual Cycle: a Review of Candidate RDoC Mechanisms. AB - PURPOSE OF REVIEW: Risk for suicidal behavior may fluctuate across the menstrual cycle. Here, we use the RDoC framework to review potential mechanisms by which the cycle may increase acute suicide risk. RECENT FINDINGS: The menstrual cycle impacts the majority of RDoC constructs linked to suicide risk, particularly among hormone-sensitive women, such as those with premenstrual dysphoric disorder or premenstrual exacerbation of a psychiatric disorder. Despite this, there are no published studies examining suicidal ideation, planning, or behavior longitudinally across the cycle. More work is needed to understand how hormone sensitivity may relate to both trait and state suicide risk. Intensive multilevel investigations of cyclical hormone effects on suicide risk through specific RDoC mechanisms are suggested. This is a fertile research area and may provide key insights regarding the mechanisms of acute suicide risk. PMID- 30293101 TI - Measurement properties of self-report questionnaires on health-related quality of life and functional health status in dysphonia: a systematic review using the COSMIN taxonomy. AB - PURPOSE: The current review was conducted to identify all self-report questionnaires on functional health status (FHS) and/or health-related quality-of life (HR-QoL) in adult populations with dysphonia (voice problems), and to evaluate the psychometric properties of the retrieved questionnaires. METHODS: A systematic review was performed in the electronic literature databases PubMed and Embase. The psychometric properties of the questionnaires were determined using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) taxonomy and checklist. Responsiveness was outside the scope of this review and as no agreed 'gold standard' measures are available in the field of FHS and HR-QoL in dysphonia, criterion validity was not assessed. Only questionnaires developed and published in English were included. RESULTS: Forty eight studies reported on the psychometric properties of 15 identified questionnaires. As many psychometric data were missing or resulted from biased study designs or statistical analyses, only preliminary conclusions can be drawn. Based on the current available psychometric evidence in the literature, the Voice Handicap Index seems to be the most promising questionnaire, followed by the Vocal Performance Questionnaire. CONCLUSIONS: More research is needed to complete missing data on psychometric properties of existing questionnaires in FHS and/or HR-QoL. Further, when developing new questionnaires, the use of item response theory is preferred above classical testing theory, as well as international consensus-based psychometric definitions and criteria to avoid bias in outcome data on measurement properties. PMID- 30293102 TI - Development of novel sericin and alginate-based biosorbents for precious metal removal from wastewater. AB - In this study, two novel low water-soluble sericin and alginate-based biosorbents were successfully developed for precious metal removal from wastewater: sericin and alginate particles chemically crosslinked by proantocyanidins (SAPAs) and sericin, alginate and polyvinyl alcohol particles (SAPVA). The proportions of proantocynidins (PAs) or polyvinyl alcohol (PVA) added to sericin (2.5% w/v) and alginate (2.0% w/v) blend were 0.5, 1.5, 2.5 and 3.5% w/v. Among these concentrations, particles produced with 0.5% w/v of PVA or 2.5% w/v of PAs presented the lowest water solubility percentages (3.74 +/- 0.05 and 3.56 +/- 0.21%, respectively) and the following metallic affinity order: AuCl4- > PdCl42- > PtCl62- > Ag+. Then, gold biosorption kinetics by SAPAs was evaluated at three gold initial concentrations (72.88, 187.12, and 273.79 mg/L), and its performance was compared to activated carbon adsorbent uptake. The data modeling revealed that the process follows pseudo-first-order kinetics and is mainly controlled by external diffusion. SAPAs before and after gold biosorption (SAPAs-gold) were characterized by scanning electron microscopy coupled with energy dispersive X ray spectroscopy, optical microscopy, helium pycnometry, mercury porosimetry, N2 physisorption, and Fourier-transform infrared spectroscopy.

AB - Industrialization and growth of the pharmaceutical companies have been a boon to the mankind in our day to day life in myriad ways. However, due to the uninhibited release of these active pharmaceutical compounds into the water systems has caused detrimental effects to the genetic pool. In this study, L cysteine-modified 3-glycidyloxypropyltrimethoxysilane-coated magnetic nanomaterial showed a maximum removal of the efficiency of 82.90% for the nanomaterial dosage of 30 mg at an initial concentration of 50 mg L-1 at pH 6.0. Further, the nanomaterial showed reusability efficiency up to 80% for three cycles. The adsorption kinetics follow the pseudo-second-order reaction and the adsorption isotherm model best fits the Langmuir isotherm proving the adsorption process to be a monolayer sorption on a monolayer surface. This magnetic nanomaterial could serve as a promising tool for the removal of pharmaceutical compounds from aqueous solutions. Graphical abstract ?. PMID- 30293103 TI - Modelling as decision support for the localisation of submarine urban wastewater outfall: Venice lagoon (Italy) as a case study. AB - Microbiological impact is critical in coastal areas where tourism is particularly important for both the local and regional economy. Submarine outfalls are commonly used to enhance the dispersion of treated sewage thus avoiding pollution along the coast. The Venice lagoon (North Italy) has a very sensitive ecosystem, due to the morphological and natural characteristics of the basin and the co existence of human activities. To preserve the lagoon, the discharge from the treatment plant for urban wastewater collected from the Venezia-Mestre agglomeration, neighbouring areas and local industries (total of 400,000 population equivalent-PE) has been moved from the lagoon to the open Adriatic Sea since November 2013 by means of an approximately 20-km pipeline. Microbiological pollution inside the lagoon can affect shellfish breeding areas instead, along the coast it affects the quality of bathing waters. In this study, and for the first time, a 3D hydrodynamic SHYFEM model (shallow water finite element model) with high spatial resolution coupled with a microbiological module has been applied to the lagoon and to the Adriatic Sea, to evaluate the effectiveness of the location of the submarine outfall. Microbiological data have been produced by the control Authority according to official analytic methods and by the plant operator. The module of survival of free Escherichia coli follows a variable rate in dependence of UV radiation, temperature and salinity in the water. Two scenarios were modelled: final discharge into the lagoon before November 2013 and after into the open sea. In the latter case, two situations have been considered, one with "Bora" and the other with "Scirocco" winds. Our results indicate that the model correctly simulates microbiological decay and dispersion. The transferral of the final discharge point far from the shoreline improves pollution dispersion, thus preserving the lagoon without evidence of impacts on the bathing waters in all meteorological conditions. PMID- 30293105 TI - Chitosan nanoparticles from Artemia salina inhibit progression of hepatocellular carcinoma in vitro and in vivo. AB - This study was conducted to evaluate the effect of chitosan nanoparticles (CNPs) isolated from Artemia salina against hepatocellular carcinoma (HCC) both in vitro (HepG2) and in vivo (diethylnitrosamine-induced HCC in rats) and to investigate the involved underlying mechanisms. Administration of CNPs decreased HCC progression as evidenced by (1) induced HepG2 cell death as detected by MTT assay; (2) induced necrosis as indicated by acridine orange/propidium iodide (AO/PI) red staining, annexin V/7-AAD positive staining (detected by flow cytometry), and upregulated expression of necrosis markers (PARP1 and its downstream target, RIP1 genes), but no effect on apoptosis as revealed by insignificant changes in caspase 3 activity and mRNA levels of Bax and AIF; (3) increased intracellular ROS and decreased mitochondrial membrane potential in HepG2; (4) decreased liver relative weight, serum levels of liver enzymes (ALT, AST, and ALP), total bilirubin, and cancer markers (AFP and GGT), number and area of GST-P positive tumor nodules; and (5) reduced oxidative stress (decrease in MDA levels) and increased activities of SOD, CAT, and GPx enzymes in rat liver. The preventive (pre-treatment) effect of CNPs was better than the therapeutic (post-treatment) effect. Collectively, administration of CNPs inhibited HCC progression in vitro and in vivo, possibly through induction of necrosis, rather than apoptosis, and induction of antioxidant enzyme activities in vivo, but with stimulation of ROS production in vitro. Thus, CNPs could be used as a promise agent for treating HCC after application of further confirmatory clinical trials. PMID- 30293106 TI - Molecular isolation and characterization of the kisspeptin system, KISS and GPR54 genes in roach Rutilus rutilus. AB - The reproduction of vertebrates is regulated by endocrine and neuro-endocrine signaling molecules acting along the brain-pituitary-gonad (BPG) axis. The understanding of the neuroendocrine role played in reproductive function has been recently revolutionized since the KiSS1/GPR54 (KiSS1r) system was discovered in 2003 in human and mice. Kisspeptins, neuropeptides that are encoded by the KiSS genes, have been recognized as essential in the regulation of the gonadotropic axis. They have been shown to play key roles in puberty onset and reproduction by regulating the gonadotropin secretion in mammals while physiological roles in vertebrates are still poorly known. In order to provide new knowledge on basic reproductive physiology in fish as well as new tools to assess impacts of endocrine disrupting compounds (EDCs), the neurotransmitter system, i.e., gene/receptor, KISS/GPR54 might constitute an appropriate biomarker. This study provides new understandings on the neuroendocrine regulation of roach reproduction as well as new molecular tools to be used as biomarkers of endocrine disruption. This work completes the set of biomarkers already validated in this species. PMID- 30293107 TI - Effect of a 12-week mixed power training on physical function in dynapenic-obese older men: does severity of dynapenia matter? AB - INTRODUCTION: Mobility disability affects nearly 15% of people aged 65 or over worldwide. Excess weight or obesity (OB), along with an accentuated loss of muscle strength (dynapenia), is recognized to be one of the most common risk factors for mobility impairment among the elderly. OBJECTIVE: To investigate the effect of a 12-week mixed power training (MPT high-velocity resistance training mixed with functional exercises) on physical function in obese older men exhibiting different severities of dynapenia. METHODS: Community-dwelling older men (69 +/- 6 years) were assigned to the study if they were considered obese (OB, fat mass >= 25% body weight, BW) and to one of the two groups according to severity of dynapenia [(handgrip strength-HS)/BW]: type 1(OB-DY1) or type 2(OB DY2), < 1 or 2SD from a young reference group. Participants followed a 12-week MPT, three times/week, 75 min/session. Main outcomes included the performance on the 4-m and 6-min walking tests, Timed Up and Go, stair and balance tests. RESULTS AND DISCUSSION: At baseline, OB-DY1 performed better than OB-DY2 in all functional tests (p < 0.05). Following the intervention, medium-to-large training effect size (ES) were observed for fat (ES = 0.21) and lean (ES = 0.32, p < 0.001) masses, functional performance (ES 0.11-0.54, p < 0.05), HS (ES = 0.10, p < 0.05) and lower limb muscle strength (ES = 0.67, p < 0.001) and power (ES = 0.60, p < 0.05). Training-by-group interaction showed that OB-DY1 lost more FM (ES = 0.11, p = 0.03) and OB-DY2 improved more HS (ES = 0.19, p = 0.006) than their counterparts. CONCLUSIONS: Seniors with obesity and severe dynapenia have poorer physical function than those in the early stage of dynapenia. Both seem to benefit from a high-velocity resistance training mixed with functional exercises, although by slightly different pathways. PMID- 30293108 TI - Diurnal variation of renal resistive index over 24-hour period in hypertensive patients and healthy controls. AB - PURPOSE: There are no data in the literature to our knowledge related to changes in renal resistive index (RRI) values over 24-h period and the importance of detecting these changes in patients who have hypertension (HT). In this study, we aimed to investigate the variation of RRI values over 24-h period and its usability in hypertensive patients. METHODS: A total of 118 subjects (80 with HT and 38 healthy controls) were included in the study. Morning, midday, evening, and midnight RRI, renal pulsatility index, and accelerated time were measured by Doppler ultrasonography (US). B-mode US and elastograpic assessment were performed only in the morning. RESULTS: Temporal RRI varied significantly (p < 0.001). The highest and lowest levels were found in the morning and evening, respectively. All temporal RRI levels were significantly higher in patients with HT (both p < 0.001). The absolute and relative increases in RRI (DeltaRRI) levels were similar in two groups. All temporal RRI measurements positively correlated with the patient age, pulse pressure, renal cortical thickness, and cortical stiffness. However, absolute-DeltaRRI and relative-DeltaRRI positively correlated with the age. Absolute-DeltaRRI positively correlated with the pulse pressure and cortical stiffness, and no correlation was observed between relative-DeltaRRI and these variables. Of the four temporal measurements, morning RRI were found to be independently associated with cortical stiffness (p < 0.001). CONCLUSIONS: RRI measurements varied over 24-h period in patients with HT and/or healthy controls. Morning RRI was significantly higher than other day time, and it is also related to renal cortical stiffness. PMID- 30293109 TI - Differentiation of duodenal gastrointestinal stromal tumors from hypervascular pancreatic neuroendocrine tumors in the pancreatic head using contrast-enhanced computed tomography. AB - PURPOSE: To determine useful contrast-enhanced computed tomography (CE-CT) features in differentiating duodenal gastrointestinal stromal tumors (duodenal GISTs) from hypervascular pancreatic neuroendocrine tumors in the pancreatic head (pancreatic head NETs). METHODS: Seventeen patients with pathologically confirmed duodenal GISTs and 25 with pancreatic NETs underwent preoperative CE-CT. CT image analysis included tumor size, morphology, and contrast enhancement. Receiver operating characteristic curves were performed, and cutoff values were calculated to determine CT findings with high sensitivity and specificity. RESULTS: CT imaging showed duodenal GISTs with higher frequencies of tumor central location close to the duodenum and a predominantly solid tumor type when compared with pancreatic head NETs (p < 0.05 for both). Duodenal GISTs were larger than pancreatic head NETs (3.3 +/- 0.9 cm vs. 2.5 +/- 1.1 cm, p = 0.03). Duodenal GISTs had significantly lower CT attenuation values (112.9 +/- 17.9HU vs. 137.4 +/- 32.1HU, p < 0.01) at the arterial phase and higher CT attenuation values at the delayed phase (94.3 +/- 7.9HU vs. 84.9 +/- 10.4HU, p < 0.01) when compared with pancreatic head NETs. A CT attenuation value of <= 135 HU at the arterial phase (30 s) was 76% sensitive, 94.1% specific, and 83.3% accurate for the diagnosis of duodenal GISTs, while a CT attenuation value of >= 89.5 HU at the delayed phase (120 s) was 93.3% sensitive, 81.8% specific, and 76.2% accurate for the diagnosis of duodenal GISTs. CONCLUSION: Tumor central location, size, texture, and contrast enhancement are valuable characteristics for the differentiation between duodenal GISTs and hypervascular pancreatic head NETs during preoperative examination.

AB - OBJECTIVE: Chronic inflammatory demyelinating polyneuropathy (CIDP) is a rare, autoimmune-inflammatory disease of the peripheral nervous system. Recently, various immunoglobulin G4 (IgG4) type auto-antibodies have been described in patients with CIDP which can effectively be removed by immunoadsorption (IA). Therefore, we prospectively evaluated the therapeutic effect of IA in 17 patients with progressive CIDP not responding to other treatment. METHODS: We prospectively evaluated the course of disease of 17 patients with CIDP who had insufficiently responded to steroids and/or IVIg previously and who received at least one cycle of IA. As clinical outcome parameter, we used a combined CIDP score of three validated scales comprising disability, motor score, and sensitivity. Seven patients received repeated treatments in regular intervals over a prolonged period up to 46 months. RESULTS: We observed a small, but significant improvement of the overall score after 2 weeks that mainly reflected an improvement of muscle strength. The median value of the combined CIDP score was 308.0 (266.0-374.5) points before IA and 330.0 (290.0-393.5) points 2 weeks after IA (p = 0.019). More importantly, all but one of seven progressive patients who received long-term immunoadsorption in regular intervals stabilized almost completely. Before IA, these patients lost 6.7 (3.0-13.1) points of combined CIDP score per month. During IA, they lost - 0.1 (0.0-0.8) points per month (p < 0.0001). INTERPRETATION: Our results suggest that IA might constitute a promising and well-tolerated therapeutic alternative in CIDP for short-term and long-term treatment. We showed that long-term treatment with IA in regular intervals can stabilize the course of disease at least in a subgroup of patients. PMID- 30293112 TI - Basal fatty acid oxidation increases after recurrent low glucose in human primary astrocytes. AB - AIMS/HYPOTHESIS: Hypoglycaemia is a major barrier to good glucose control in type 1 diabetes. Frequent hypoglycaemic episodes impair awareness of subsequent hypoglycaemic bouts. Neural changes underpinning awareness of hypoglycaemia are poorly defined and molecular mechanisms by which glial cells contribute to hypoglycaemia sensing and glucose counterregulation require further investigation. The aim of the current study was to examine whether, and by what mechanism, human primary astrocyte (HPA) function was altered by acute and recurrent low glucose (RLG). METHODS: To test whether glia, specifically astrocytes, could detect changes in glucose, we utilised HPA and U373 astrocytoma cells and exposed them to RLG in vitro. This allowed measurement, with high specificity and sensitivity, of RLG-associated changes in cellular metabolism. We examined changes in protein phosphorylation/expression using western blotting. Metabolic function was assessed using a Seahorse extracellular flux analyser. Immunofluorescent imaging was used to examine cell morphology and enzymatic assays were used to measure lactate release, glycogen content, intracellular ATP and nucleotide ratios. RESULTS: AMP-activated protein kinase (AMPK) was activated over a pathophysiologically relevant glucose concentration range. RLG produced an increased dependency on fatty acid oxidation for basal mitochondrial metabolism and exhibited hallmarks of mitochondrial stress, including increased proton leak and reduced coupling efficiency. Relative to glucose availability, lactate release increased during low glucose but this was not modified by RLG. Basal glucose uptake was not modified by RLG and glycogen levels were similar in control and RLG-treated cells. Mitochondrial adaptations to RLG were partially recovered by maintaining euglycaemic levels of glucose following RLG exposure. CONCLUSIONS/INTERPRETATION: Taken together, these data indicate that HPA mitochondria are altered following RLG, with a metabolic switch towards increased fatty acid oxidation, suggesting glial adaptations to RLG involve altered mitochondrial metabolism that could contribute to defective glucose counterregulation to hypoglycaemia in diabetes. PMID- 30293113 TI - A cost analysis of intensified vs conventional multifactorial therapy in individuals with type 2 diabetes: a post hoc analysis of the Steno-2 study. AB - AIMS/HYPOTHESIS: Long-term follow-up of the Steno-2 study demonstrated that intensified multifactorial intervention increased median lifespan by 7.9 years and delayed incident cardiovascular disease by a median of 8.1 years compared with conventional multifactorial intervention during 21.2 years of follow-up. In this post hoc analysis of data from the Steno-2 study, we aimed to study the difference in direct medical costs associated with conventional vs intensified treatment. METHODS: In 1993, 160 Danish individuals with type 2 diabetes and microalbuminuria were randomised to conventional or intensified multifactorial target-driven intervention for 7.8 years. Information on direct healthcare costs was retrieved from health registries, and the costs in the two groups of participants were compared by bootstrap t test analysis. RESULTS: Over 21.2 years of follow-up, there was no difference in total direct medical costs between the intensified treatment group, ?12,126,900, and the conventional treatment group, ?11,181,700 (p = 0.48). The mean cost per person-year during 1996-2014 was significantly lower in the intensified treatment group (?8725 in the intensive group and ?10,091 in the conventional group, p = 0.045). The main driver of this difference was reduced costs associated with inpatient admissions related to cardiovascular disease (p = 0.0024). CONCLUSIONS/INTERPRETATION: Over a follow-up period of 21.2 years, we found no difference in total costs and reduced cost per person-year associated with intensified multifactorial treatment for 7.8 years compared with conventional multifactorial treatment. Considering the substantial gain in life-years and health benefits achieved with intensified treatment, we conclude that intensified multifaceted intervention in high-risk individuals with type 2 diabetes seems to be highly feasible when balancing healthcare costs and treatment benefits in a Danish healthcare setting. PMID- 30293114 TI - Cinnamaldehyde inhibit Escherichia coli associated with membrane disruption and oxidative damage. AB - In this study, the antimicrobial mechanism of cinnamaldehyde (CIN) against Gram negative Escherichia coli ATCC 25922 (E. coli) based on membrane and gene regulation was investigated. Treatment with low concentration (0, 1/8, 1/4, 3/8 MIC) of CIN can effectively suppress the growth of E. coli by prolonging its lag phase and Raman spectroscopy showed obvious distinction of the E. coli after being treated with these concentration of CIN. The determination of relative conductivity indicated that CIN at relatively high concentration (0, 1, 2, 4 MIC) can increase the cell membrane permeability, causing the leakage of cellular content. Besides, the content of malondialdehyde (MDA) and the activity of total superoxide dismutase (SOD) of E. coli increased with increasing treatment concentration of CIN, implying that CIN can cause oxidative damage on E. coli cell membrane and induce the increase of total SOD activity to resist this oxidative harm. Moreover, quantitative real-time RT-PCR (qRT-PCR) analysis revealed the relationship between expression of antioxidant genes (SODa, SODb, SODc) and treatment CIN concentration, suggesting that SOD, especially SODc, played a significant role in resistance of E. coli to CIN. The underlying inactivation processing of CIN on E. coli was explored to support CIN as a potential and natural antimicrobial agent in food industry.

AB - Since their market approval, direct oral anticoagulants (DOACs) are being increasingly used for stroke prevention in patients with atrial fibrillation. However, the management of DOAC-treated patients with stroke poses several challenges for physicians in everyday clinical practice, both in the acute setting and in long-term care. This has spurred extensive research activity in the field over the past few years, which we review here.

PMID- 30293116 TI - A review on iron chelators as potential therapeutic agents for the treatment of Alzheimer's and Parkinson's diseases. AB - Iron plays a vital role in several cellular functions due to its unique physiochemical properties. Iron concentration increases in the brain with age due to multiple factors. Excessive amount of iron can lead to formation of reactive oxygen species. Neurodegenerative disorders are characterized by iron supplemented increase in oxidative stress and cellular damage. There is an urgent need of novel therapies which should not only provide symptomatic relief but also be able to modulate iron accumulation in the brain. Therefore, the development of novel iron chelators as neuroprotective agents for the treatment of neurodegeneration is an emerging trend. Several iron chelators including 8 hydroxyquinoline derivatives, dopaminergic agonists and natural products are under preclinical and clinical investigations for the treatment of neurodegenerative disorders. PMID- 30293117 TI - Apatinib as maintenance therapy in extensive-stage small-cell lung cancer: results from a single-center retrospective study. AB - PURPOSE: To evaluate the efficacy of maintenance apatinib after chemotherapy for extensive-stage (ED) small-cell lung cancer (SCLC). PATIENTS AND METHODS: This was a retrospective analysis of 23 cases of extensive-stage SCLC admitted to the Affiliated Cancer Hospital of Zhengzhou University from January 2015 to December 2017. The patients without progression after induction chemotherapy received apatinib 250 mg per day until disease progression or unacceptable toxicity occurred. We analyzed the median progression-free survival (PFS), median overall survival (OS) and safety. RESULTS: Of 23 enrolled patients, 1 was lost to follow up. The median PFS from the time of maintenance therapy was 4.1 months (95% CI 3.63-4.57 months). The median PFS from the time of induction chemotherapy was 8.3 months (95% CI 7.20-9.40 months). The median OS from the time of maintenance therapy was 12.5 months (95% CI 5.51-19.49 months). The median OS from the time of induction chemotherapy was 17.0 months (95% CI 9.86-24.14 months). The most frequent treatment-related adverse events were hand-foot syndrome (43.5%, 10/23) and secondary hypertension (30.4%, 7/23), followed by fatigue, proteinuria, nausea, and oral mucositis (17.4%, 13.0%, 13.0%, and 8.7%, respectively). Hematologic toxicity included thrombocytopenia (30.4%), leucopenia (26.1%), and anemia (17.4%). The main grade 3 or 4 toxicities were hand-foot syndrome (8.7%, 2/23) and hypertension (4.3%, 1/23). CONCLUSION: Maintenance apatinib was safe and achieved encouraging PFS and OS in extensive-stage SCLC. PMID- 30293118 TI - Progress in gene therapy using oncolytic vaccinia virus as vectors. AB - BACKGROUND: Vaccinia virus was widely used in the World Health Organization's smallpox eradication campaign and is currently a promising vector for gene therapy owing to its unique characteristics. Vaccinia virus can selectively replicate and propagate productively in tumor cells, resulting in oncolysis. In addition, rapid viral particle production, wide host range, large genome size (approximately 200 kb), and safe handling render vaccinia virus a suitable vector for gene therapy. MATERIALS AND METHODS: Cancer vaccines and gene therapy are being studied in clinical trials and experiment researches. However, we put forward unique challenges of optimal selection of foreign genes, administration and modification of VACV, personalized medicine, and other existing problems, based on current researches and our own experiments. CONCLUSION: This review presents an overview of the vaccinia virus from its mechanisms to medical researches and clinical trials. We believe that the solution to these problems will contribute to understanding mechanisms of VACV and provide a theoretical basis for clinical treatment. PMID- 30293119 TI - Pre-treatment metabolic tumor volume predicts tumor metastasis and progression in high-grade salivary gland carcinoma. AB - PURPOSE: High-grade salivary gland carcinoma (SGC) shows a high rate of metastasis and post-treatment recurrence, resulting in poor patient survival. Therefore, we evaluated the utility of pre-treatment 18F-FDG PET/CT parameters in predicting metastasis, tumor progression, and survival of high-grade SGC patients. METHODS: This observational study included 75 patients with previously untreated high-grade SGC who underwent pre-treatment 18F-FDG PET/CT scanning and subsequent treatment. Standardized uptake values (SUV), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) were measured on pre-treatment 18F-FDG PET/CT. Logistic regression analysis was used to identify the relationship of these factors with metastasis. Cox proportional hazard regression analyses were used to identify associations between PET parameters and both progression-free survival (PFS) and overall survival (OS). RESULTS: A total of 36 (48%) patients had neck or distant metastases at initial staging. After controlling for clinical factors, MTV (> 8.8 mL) was an independent factor for initial metastasis (adjusted odds ratio 4.80, 95% confidence interval 1.09-21.20; P = 0.039). All PET parameters of SUVmax (> 4.3), SUVmean (> 3.0), SUVpeak (3.9), MTV (> 8.8 mL), and TLG (> 31.1 g) were significant variables for PFS (all P < 0.05), while MTV and TLG were significant factors for OS. After controlling for clinicopathological factors, MTV (adjusted hazard ratio 4.36, 95% confidence interval 1.69-11.26; P = 0.002) and TLG (3.41, 1.47-7.91; P = 0.004) were significantly associated with PFS, but not OS. CONCLUSIONS: MTV is useful among quantitative PET measurements for predicting initial metastasis and PFS in patients with high-grade SGC. PMID- 30293121 TI - Relative age and ADHD symptoms, diagnosis and medication: a systematic review. AB - There is a growing international literature investigating the relationship between attention-deficit/hyperactivity disorder (ADHD) and younger relative age within the school year, but results have been mixed. There are no published systematic reviews on this topic. This study aimed to systematically review the published studies on the relative age effect in ADHD. Systematic database searches of: Medline, Embase, PsycINFO, Web of Science, ERIC, Psychology and Behavioral Sciences Collection and The Cochrane Library were conducted. Studies were selected which investigated the relative age effect in ADHD in children and adolescents. Twenty papers were included in the review. Sixteen (of 20) papers reported a significantly higher proportion of relatively younger children being diagnosed with ADHD and/or receiving medication for this. Meta-analyses involving 17 of these 20 papers revealed a modest relative age effect in countries with higher prescribing rates, risk ratio = 1.27 (95% CI 1.19-1.35) for receipt of medication. The relative age effect is well demonstrated in countries with known higher prescribing rates. Amongst other countries, there is also increasing evidence for the relative age effect, however, there is high heterogeneity amongst studies. Further research is needed to understand the possible reasons under-pinning the relative age effect and to inform attempts to reduce it. PMID- 30293120 TI - Kaposiform hemangioendothelioma without cutaneous involvement. AB - PURPOSE: We sought to characterize the clinical features and management of patients diagnosed as Kaposiform hemangioendothelioma (KHE) without cutaneous involvement. METHODS: The electronic patient chats at six Triple A hospitals in China were searched to find all patient diagnoses with KHE without cutaneous involvement. RESULTS: Of 30 patients (mean age at diagnosis, 55.6 months), 17 (56.7%) were male. Fourteen (46.7%) patients were associated with Kasabach Merritt phenomenon (KMP). Patients with KMP were significantly more likely to have lesions involving truck compared to patients without KMP (odds ratio 10.000; 95% confidence interval 1.641-60.921; P = 0.011). Other common complication included severe anemia and decreased range of motion. In the majority of cases (93.3%), the lesions were highly infiltrative and locally invasive with ill defined margins. Histological examination was required in all patients without KMP for precise diagnosis. In all, 16 (53.3%) patients received corticosteroid treatment, 19 (63.3%) received oral sirolimus treatment, 7 (23.3%) received intravenous vincristine, and 5 (16.7%) patients used propranolol. Patients had varied responses to conventional drugs, whereas all patients receiving sirolimus treatment had better response. In all, three patients (10%) died of disease, all presented with KMP. Feature of these recalcitrant cases (death) included young age, visceral location, extensive involvement, and lack of improvement with high dose corticosteroids. CONCLUSIONS: Our study clearly demonstrated that KHE without cutaneous involvement could be associated with important complication, which might result in death or severe morbidity. Increased awareness of KHE without cutaneous involvement is required for early diagnosis and aggressive therapy in an attempt to prevent complication. PMID- 30293122 TI - Suicidal behaviors and irritability in children and adolescents: a systematic review of the nature and mechanisms of the association. AB - While many psychiatric disorders are associated with an increased risk for suicidal behaviors (SB) in children and adolescents, a few studies have explored the role of clinical symptoms based on a dimensional approach. Irritability is seen as a marker, a general psychopathology, and a symptom of both externalizing and internalizing disorders. In this review, we are interested in determining whether and how irritability can predict SB in youth. First, we reviewed consistencies and variation in the literature linking irritability to suicidal ideation (SI) and suicide attempt (SA). Second, based on the available models, we proposed specific mechanistic pathways, whereby irritability may modulate the risk for SB. Irritability has been found associated with SB both in cross sectional and in longitudinal studies. The relation is consistent in different settings (i.e., general population and clinical settings) and across psychiatric disorders. The association is reduced but persists after adjusting for psychiatric disorder, including depression. On one hand, irritability constitutes a risk factor for SI via the onset of internalized disorder. On the other hand, irritable youth may be more prone to attempt suicide when experiencing SI. The measures for irritability were heterogeneous. A limited number of studies were designed to explore the role of mediators and/or moderators. Recognizing irritability in children and adolescents is a key issue with regards to suicide prevention. PMID- 30293123 TI - Low back pain in Brazilian medical students: a cross-sectional study in 629 individuals. AB - Low back pain (LBP) is a common problem in the general population. Medical students may be at risk of LBP because of demanding curricula. To study the prevalence of LBP in Brazilian medical students and the associated factors. Six hundred twenty-nine medical students (72.8% females, mean age of 23 years old) answered a questionnaire containing epidemiological data; data on presence and frequency of LBP, use of painkillers, and LBP interference in daily activities; number of sitting and exercising hours/day, posture habits. They also filled a VAS (or visual analogic scale) on the own perception of anxiety, depression, fatigue, and the Roland Morris functional questionnaire for LBP. In this sample, 81.7% had periods of recurrent LBP that was more common in females (77.6% vs 51.3%; p < 0.0001) and associated with bad posture habits (p < 0.0001). Number of sitting hours, exercising, and study period at school could not be associated with LBP. The mean Roland Morris result was 4.0; IQR = 2-7 and its value showed a modest correlation with VAS of anxiety (rho = 0.21) and depression (rho = 0.33). LBP interfered with social activities in 20.5%, with physical activities in 33.1%, and in school activities in 29.2%. There is a high prevalence of LBP in medical students, mainly females, associated with bad posture habits. Physical dysfunction for LBP showed correlation with anxiety and depression. PMID- 30293125 TI - Visfatin and insulin levels and cigarette smoking are independent risk factors for hidradenitis suppurativa: a case-control study. AB - Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease. HS has been associated with obesity, adipokine imbalance, dyslipidemia, pro-inflammation, and metabolic syndrome (MS). The aim of this study was to determine the association between HS, and serum visfatin levels (SVLs), small-dense low-density lipoprotein cholesterol (sdLDL-C), and ischemia-modified albumin (IMA), as well as the association between HS, and smoking, alcohol consumption, anthropometric measurements, blood pressures (BPs), fasting blood glucose (FBG) and lipids, inflammatory markers, homocysteine, uric acid (UA), serum insulin levels (SILs), insulin resistance (IR) and MS, so as to identify relevant risk factors for HS. This case-control study included 40 patients (M/F: 23/17) and 40 age- and gender matched controls (M/F: 23/17). Demographic data, smoking status and alcohol consumption, personal and family medical history, previous and current treatments were noted. Anthropometric data, BPs, FBG and lipids, homocysteine, UA, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and high sensitivity CRP (hs-CRP), hemoglobin A1c (HbA1c), SILs, SVLs, IMA and sdLDL-C were measured. Homeostasis model assessment for IR (HOMA-IR) was calculated. The associations were made by univariate and multivariate analyses. Univariate analysis showed that there was a significant association between HS and smoking, pack-years of smoking, weight, body mass index (BMI), waist circumference (WC), triglycerides (TGs), high-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, SILs, CRP, hs-CRP, homocysteine, UA, ESR, HOMA-IR, SVLs, and MS. After adjusting for BMI and smoking status, the SVLs, SILs, and hs-CRP levels remained higher in the patients than in the controls (P = 0.02, P = 0.01, and P = 0.02, respectively). Multivariate analysis showed that there was a significant association between HS, and the SVLs and SILs, and smoking. Each unit increase in the SVL (P = 0.003, 95% CI 1.16-2.11) and SIL (P = 0.03, 95% CI 1.01 1.17) increased the risk of HS 1.56- and 1.09-fold, respectively. Furthermore, smoking was associated with a 14.87-fold increase in the risk of HS (P = 0.001, 95% CI 2.82-78.56). This study indicates that HS patients have higher SVLs, SILs, and hs-CRP levels than healthy controls-independent of BMI and smoking status. The SVL and SILs and smoking were independent risk factors for HS. PMID- 30293124 TI - Mono-exponential and bi-exponential model-based diffusion-weighted MR imaging and IDEAL-IQ sequence for quantitative evaluation of sacroiliitis in patients with ankylosing spondylitis. AB - To evaluate the utility of mono-exponential and bi-exponential model-based diffusion-weighted MR imaging and IDEAL-IQ sequence for differentiating the activity of sacroiliitis in ankylosing spondylitis (AS). AS patients were divided into active group (n = 30) and inactive group (n = 28) according to Ankylosing Spondylitis Disease Activity Score (ASDAS) with C-reactive protein (CRP). In addition, 30 healthy volunteers were chosen as healthy group. Subjects were scanned by conventional MRI, diffusion-weighted imaging, and IDEAL-IQ sequence. Apparent diffusion coefficient (ADC), true diffusion coefficient (D), pseudodiffusion coefficient (D*), perfusion fraction (f), and fat fraction (FF) values were measured, and their relative values (rADC, rD, rD*, rf) were calculated by the formula ADC (D,D*,f)lesion/ADC (D,D*,f)reference, respectively. The ADC, D, rADC, and rD of active group were the highest among the three groups, followed by inactive and healthy group. However, D* and rD* showed no significant difference among the three groups. FF was significantly higher in inactive group than in healthy and active group. ADC and D had significantly higher AUCs than f for differentiating active group from healthy group, while FF had the highest AUC for distinguishing inactive sacroiliitis from healthy group. DWI and IDEAL-IQ imaging are helpful in quantitatively assessing the activity of sacroiliitis in AS patients. PMID- 30293126 TI - Rivaroxaban versus Warfarin in Patients with Mechanical Heart Valve: Rationale and Design of the RIWA Study. AB - INTRODUCTION: Mechanical heart valves (MHV) are extremely durable, but they require permanent use of anticoagulation to prevent thromboembolic events. The only approved therapeutic options are vitamin K antagonists (VKAs), such as warfarin. As a drug class, clinical management is difficult, therefore new alternatives need to be evaluated. METHODS: RIWA is a phase II/III, prospective, open-label, randomized, pilot study designed to investigate oral rivaroxaban 15 mg twice daily compared with dose-adjusted warfarin for the prevention of stroke (ischemic or hemorrhagic) and systemic embolism in patients with MHV, from August 2018 to December 2019. Patients will undergo transesophageal echocardiography at the beginning and the end of the study (follow-up time 90 days). On an explanatory basis, all events will be analyzed, including stroke, peripheral systemic embolism, valve thrombosis, significant bleeding and death. DISCUSSION: Warfarin and similar VKAs are standard therapy for patients with an MHV. Even with the appropriate use of therapy, the incidence of thromboembolic events is high at 1-4% per year. Furthermore, bleeding risk is significant, ranging from 2 to 9% per year. The new frontier to be overcome in relation to use of the new oral anticoagulants is undoubtedly in patients with MHV. A significant portion of people with MHV worldwide will benefit if noninferiority of these new agents is confirmed. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03566303. Recruitment Status: Recruiting. First Posted: 25 June 2018. Last Update Posted: 25 June 2018. PMID- 30293128 TI - Functional Behavior-Based Cognitive-Behavioral Therapy for Obsessive Compulsive Behavior in Children with Autism Spectrum Disorder: A Randomized Controlled Trial. AB - Children with autism spectrum disorder (ASD) experience obsessions and compulsions similar to those specified in DSM-5 for obsessive compulsive disorder yet little controlled research exists on treating these behaviours. Thirty-seven children (7-13 years old) were randomly assigned to a 9-week functional behavior based cognitive behavior therapy (Fb-CBT) or Treatment As Usual. Independent assessors administered measures pre- and post-treatment and at 6-months. Two primary outcome measures indicated statistically significant differences between groups, with large corrected effect sizes (Hedge's g = 1.00 and 1.15, respectively). This is the first known RCT to exclusively treat obsessive compulsive behaviors (OCBs) in children and youth with high functioning (IQ >= 70) ASD, and suggests that Fb-CBT treatment shows promise in decreasing these behaviors and improving quality of life. Trial Registration This trial was registered with ClinicalTrials.gov (ID: NCT03123146). PMID- 30293129 TI - Combination of Soy Protein, Amylopectin, and Chromium Stimulates Muscle Protein Synthesis by Regulation of Ubiquitin-Proteasome Proteolysis Pathway after Exercise. AB - The present study was undertaken to investigate the effect of the combination of soy protein, amylopectin, and chromium (SAC) on muscle protein synthesis and signal transduction pathways involved in protein synthesis (mTOR pathways, IGF-1, and AktSer473) and proteolysis (FOXO1Ser256; MURF1, MAFbx) after exercise. Thirty five Wistar rats were randomly divided into five groups: (1) control (C); (2) exercise (E); (3) exercise + soy protein (3.1 g/kg/day) (E + S); (4) exercise + soy protein + chromium (E + S + Cr); (5) exercise + soy protein + amylopectin + chromium (E + S + A + Cr). Post-exercise ingestion of SAC significantly increased the fractional rate of protein synthesis (FSR), insulin, glycogen, and amino acid levels with the highest effect observed in E + S + A + Cr group (P ? 0.05). However, SAC supplementation decreased the lactic acid concentration (P ? 0.05). A reduction in forkhead box protein O1 (FOXO1) and forkhead box protein O3 (FOXO3) (regulators of ubiquitin-related proteolysis) and muscle atrophy F-box (MAFbx) levels was noted after treatment with SAC (P < 0.05). Insulin-like growth factor 1(IGF-1) level was increased in the E + S, E + S + Cr, and E + S + A + Cr groups (P < 0.05). While the phosphorylation of 4E-BP1Thr37/46, AktSer473, mTORSer2448, and S6K1Thr389 levels increased after SAC supplementation, phosphorylated muscle ring finger 1 (MuRF-1, an E3-ubiquitin ligase gene) was found to be significantly lower compared with the E group (P ? 0.05). These results indicate that SAC supplementation improves FSR, insulin, and glycogen levels after exercise. SAC improves protein synthesis by inhibiting the ubiquitin proteasome pathway and inducing anabolic metabolism. PMID- 30293127 TI - Coexpression of octopine and succinamopine Agrobacterium virulence genes to generate high quality transgenic events in maize by reducing vector backbone integration. AB - Agrobacterium-mediated transformation is a complex process that is widely utilized for generating transgenic plants. However, one of the major concerns of this process is the frequent presence of undesirable T-DNA vector backbone sequences in the transgenic plants. To mitigate this deficiency, a ternary strain of A. tumefaciens was modified to increase the precision of T-DNA border nicking such that the backbone transfer is minimized. This particular strain supplemented the native succinamopine VirD1/VirD2 of EHA105 with VirD1/VirD2 derived from an octopine source (pTi15955), the same source as the binary T-DNA borders tested here, residing on a ternary helper plasmid containing an extra copy of the succinamopine VirB/C/G operons and VirD1. Transformation of maize immature embryos was carried out with two different test constructs, pDAB101556 and pDAB111437, bearing the reporter YFP gene and insecticidal toxin Cry1Fa gene, respectively, contained in the VirD-supplemented and regular control ternary strains. Molecular analyses of ~ 700 transgenic events revealed a significant 2.6 fold decrease in events containing vector backbone sequences, from 35.7% with the control to 13.9% with the VirD-supplemented strain for pDAB101556 and from 24.9% with the control to 9.3% with the VirD-supplemented strain for pDAB111437, without compromising transformation efficiency. In addition, while the number of single copy events recovered was similar, there was a 24-26% increase in backbone free events with the VirD-supplemented strain compared to the control strain. Thus, supplementing existing VirD1/VirD2 genes in Agrobacterium, to recognize diverse T-DNA borders, proved to be a useful tool to increase the number of high quality events in maize.

AB - Environmental metal exposure, as well as dietary metals, may adversely affect semen quality even as others play an essential role in normal spermatogenesis and fertility. Measures of seminal fluid metals have therefore been of high interest in the last several decades but have shown inconsistent results in correlations with some semen quality parameters. As well, environmental metal measures across various body fluid matrices have not been consistently correlated contrary to what one might hypothesize based on a systemic body burden of metal. This may be due to the body fluid matrices assessed and to other differences in laboratory methods and sample preparation. Measures of uranium, a potentially toxic metal in humans, have not previously been reported in the semen of environmentally metal exposed populations. We report here uranium seminal fluid results and the high correlation of uranium concentrations across several body fluid matrices in a cohort of military veterans exposed to depleted uranium in combat events during the Iraqi Gulf War. These results inform the risk communication conversation for exposed populations and broaden the public health assessments from various exposure scenarios. PMID- 30293131 TI - Enhancement in Iron Absorption on Intake of Chemometrically Optimized Ratio of Probiotic Strain Lactobacillus plantarum 299v with Iron Supplement Pearl Millet. AB - This research article aims to establish the intake ratio of probiotic Lactobacillus plantarum 299v with iron supplement pearl millet by central composite design of response surface methodology so as to enhance iron absorption. In anemic rat models, the food intake pattern, body weight, hemoglobin content, and hematocrit values were found to be significantly increased on treatment with pearl millet:probiotic; however, incorporation of probiotics at lower dose (0.5 g) was significantly (p < 0.05) effective in enhancing iron absorption, and further increment in probiotic doses (1.0 g) did not produce significant increase in hemoglobin and hematocrit values as evidenced by the experimental findings. PMID- 30293132 TI - A family case of X-linked Alport syndrome patients with a novel variant in COL4A5. AB - We herein report 2 Japanese patients with X-linked Alport syndrome (XLAS), with a novel variant in COL4A5. Patient 1 was a 16-year-old Japanese girl with a history of microscopic hematuria, without proteinuria, renal dysfunction, deafness, or ocular abnormalities. At 13 years of age, renal biopsy was performed; however, a diagnosis of AS was not considered. When her mother (patient 2) was 40 years of age (3 years after patient 1 underwent a renal biopsy), patient 2 was found to have asymptomatic hematuria, proteinuria, and an increased serum creatinine level, without deafness and ocular abnormalities. Subsequently, immunofluorescence staining for alpha 5 chains of type IV collagen was performed in patient 1. Pathological findings were consistent with AS, and genetic analysis demonstrated that both patients had a heterozygous mutation in COL4A5 (NM_000495.4: exon41:c.C3769T: p.Q1257X). To date, more than 900 different COL4A5 mutations have been identified; however, this variant has not been previously described. Physicians have to consider AS when they perform a renal biopsy in all patients with hematuria despite absent/present of family history, hearing loss, and ocular abnormality. Especially, when findings of light microscopy and immunofluorescence microscope are unclear, it should be considered carefully. Electron microscopy findings are very important. PMID- 30293133 TI - Gut Microbiota Imbalance Can Be Associated with Non-malabsorptive Small Bowel Shortening Regardless of Blind Loop. AB - INTRODUCTION: Some traditional bariatric surgery procedures may lead to functional gut shortening, which may unsettle the fine-tuned gastrointestinal physiology and affect gut microbiota balance. PURPOSE: Evaluate the gut microbiota behavior in rat models facing gut shortening due to intestinal bypass. MATERIALS AND METHODS: Wistar rats (n = 17) were randomly distributed in three groups: (1) sham group (n = 5); (2) blind loop group (n = 6); and (3) resection group (n = 6). Intestinal samples and feces were analyzed to measure bacterial concentrations (small intestinal bacterial overgrowth-SIBO) 12 weeks after the experimental procedures. Bacterial translocation (BT) was investigated in the mesenteric lymph node (MLN), liver, spleen, and lung of the animals. In addition, inflammatory aspects were investigated in their liver and small bowel through histological analysis. RESULTS: Regardless of blind loop, gut shortening groups recorded similar high level of bacterial concentrations in intestine compartments, greater than that of the sham group (p <= 0.05). BT was only observed in the MLN of gut shortening models, with higher percentage in the blind loop group (p <= 0.05). The gut and liver histopathological analysis showed similar low-grade chronic inflammation in both gut shortening groups, likely associated with SIBO/BT events. CONCLUSION: Sustained SIBO/BT was associated with proximal gut shortening in half regardless of blind loop, whereas the GI tract's ability to restore gut microbiota balance after a surgical challenge on the small bowel appears to be linked to the functional remaining gut. PMID- 30293134 TI - Long-Term Outcomes After Bariatric Surgery: a Systematic Review and Meta-analysis of Weight Loss at 10 or More Years for All Bariatric Procedures and a Single Centre Review of 20-Year Outcomes After Adjustable Gastric Banding. AB - INTRODUCTION: Durability is a key requirement for the broad acceptance of bariatric surgery. We report on durability at and beyond 10 years with a systematic review and meta-analysis of all reports providing data at 10 or more years and a single-centre study of laparoscopic adjustable gastric banding (LAGB) with 20 years of follow-up. METHODS: Systematic review with meta-analysis was performed on all eligble reports containing 10 or more years of follow-up data on weight loss after bariatric surgery. In addition, a prospective cohort study of LAGB patients measuring weight loss and reoperation at up to 20 years is presented. RESULTS: Systematic review identified 57 datasets of which 33 were eligible for meta-analysis. Weighted means of the percentage of excess weight loss (%EWL) were calculated for all papers included in the systematic review. Eighteen reports of gastric bypass showed a weighted mean of 56.7%EWL, 17 reports of LAGB showed 45.9%EWL, 9 reports of biliopancreatic bypass +/- duodenal switch showed 74.1%EWL and 2 reports of sleeve gastrectomy showed 58.3%EWL. Meta analyses of eligible studies demonstrated comparable results. Reoperations were common in all groups. At a single centre, 8378 LAGB patients were followed for up to 20 years with an overall follow-up rate of 54%. No surgical deaths occurred. Weight loss at 20 years (N = 35) was 30.1 kg, 48.9%EWL and 22.2% total weight loss (%TWL). Reoperation rate was initially high but reduced markedly with improved band and surgical and aftercare techniques. CONCLUSION: All current procedures are associated with substantial and durable weight loss. More long term data are needed for one-anastomosis gastric bypass and sleeve gastrectomy. Reoperation is likely to remain common across all procedures. PMID- 30293135 TI - Short-Term Outcomes of Conversion of Failed Gastric Banding to Laparoscopic Sleeve Gastrectomy or Roux-En-Y Gastric Bypass: a Meta-Analysis. AB - BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) is associated with high long-term failure rates, often requiring conversion to an alternative bariatric procedure. The most efficacious procedure after failed LAGB is subject to debate. Our objective was to compare 12-month weight loss following laparoscopic sleeve gastrectomy (LSG) vs. laparoscopic Roux-en-Y gastric bypass (LRYGB) performed for insufficient weight loss or weight regain after LAGB. METHODS: A systematic search was conducted in PubMed and Medline for English language studies comparing weight loss after a conversion surgery for failed gastric banding. We examined studies with patients who had at least 1-year follow up and included conversions to both LSG and LRYGB. A fixed effects model was created, and variance measures were calculated to measure heterogeneity. Both were analyzed for significance. All statistical analyses were conducted with the "meta" package in R 3.3.2. RESULTS: The initial search produced 17 studies. Six studies, consisting of 205 LSG and 232 LRYGB patients, met our inclusion criteria and were included in the review. Heterogeneity among studies was high (Q = 23.1; p < 0.001). There was no statistically significant difference in weight loss after 12 months between the groups (p = 0.14). CONCLUSIONS: It remains unknown which conversion procedure is more appropriate to perform after a failed gastric band in order to achieve the highest weight loss potential. In our meta-analysis, there was no difference in weight loss after 12 months in patients who were converted to LSG or LRYGB. Further studies and longer follow-up comparisons are required before firm conclusions can be drawn. PMID- 30293137 TI - Fetal brain morphometry on prenatal magnetic resonance imaging in congenital diaphragmatic hernia. AB - BACKGROUND: Many infants with congenital diaphragmatic hernia (CDH) show brain abnormality on postnatal brain MRI related to severity of CDH, degree of lung hypoplasia, intrathoracic liver, right diaphragmatic hernia and large diaphragmatic defect. It is not known whether these factors affect brain growth in utero in CDH. OBJECTIVE: To assess prenatal brain morphometry and abnormalities on fetal MR in congenital diaphragmatic hernia. MATERIALS AND METHODS: We retrospectively reviewed 109 fetal MRIs in 63 fetuses with CDH from 2009 to 2014 (27 died before discharge, 36 survived to discharge). We compared brain injury and gestational-age-corrected z-scores of brain measurements between survivors and non-survivors. We assessed correlations between brain abnormalities and CDH severity. RESULTS: Enlarged extraaxial space was the most common abnormality, frequently seen on fetal MRI at >28 weeks of gestation, similar in survivors versus non-survivors. Anteroposterior cerebellar vermis dimension at >28 weeks of gestation was smaller in non-survivors compared to survivors (P=.02) and positively correlated with observed/expected total fetal lung volume (P=.01). Transverse cerebellar diameter at >28 weeks of gestation was also positively correlated with observed/expected total fetal lung volume (P=.04). We did not identify maturational delay, abnormal parenchymal signal or intracranial hemorrhage on fetal MRI. CONCLUSION: Enlarged extraaxial spaces in the third trimester was the most common abnormality on fetal MRI in congenital diaphragmatic hernia. Cerebellar dimensions on fetal MRI are associated with CDH severity. There was no major brain parenchymal injury on fetal MRI, even in the third trimester, in CDH survivors and non-survivors. PMID- 30293138 TI - Pancreatic heterotopia in a neonatal abdominopelvic cyst. AB - Pancreatic heterotopia is a rare congenital anomaly more commonly incidentally found in adults. While intra-abdominal cysts found on prenatal imaging are not uncommon, we examine a case of pancreatic heterotopia presenting in an abdominopelvic cyst on prenatal imaging. At birth, the neonate was found to have hypoglycemia unresponsive to treatment that resolved after cyst resection. We will review the etiology, imaging findings and clinical course of this anomaly, which should be considered in the differential diagnosis of newborns presenting with unexplained hypoglycemia. PMID- 30293136 TI - Nuclear calcineurin is a sensor for detecting Ca2+ release from the nuclear envelope via IP3R. AB - In continuously beating cells like cardiac myocytes, there are rapid alterations of cytosolic Ca2+ levels. We therefore hypothesize that decoding Ca2+ signals for hypertrophic signaling requires intracellular Ca2+ microdomains that are partly independent from cytosolic Ca2+. Furthermore, there is a need for a Ca2+ sensor within these microdomains that translates Ca2+ signals into hypertrophic signaling. Recent evidence suggested that the nucleus of cardiac myocytes might be a Ca2+ microdomain and that calcineurin, once translocated into the nucleus, could act as a nuclear Ca2+ sensor. We demonstrate that nuclear calcineurin was able to act as a nuclear Ca2+ sensor detecting local Ca2+ release from the nuclear envelope via IP3R. Nuclear calcineurin mutants defective for Ca2+ binding failed to activate NFAT-dependent transcription. Under hypertrophic conditions Ca2+ transients in the nuclear microdomain were significantly higher than in the cytosol providing a basis for sustained calcineurin/NFAT-mediated signaling uncoupled from cytosolic Ca2+. Measurements of nuclear and cytosolic Ca2+ transients in IP3 sponge mice showed no increase of Ca2+ levels during diastole as we detected in wild-type mice. Nuclei, isolated from ventricular myocytes of mice after chronic Ang II treatment, showed an elevation of IP3R2 expression which was dependent on calcineurin/NFAT signaling and persisted for 3 weeks after removal of the Ang II stimulus. These data provide an explanation how Ca2+ and calcineurin might regulate transcription in cardiomyocytes in response to neurohumoral signals independently from their role in cardiac contraction control. KEY MESSAGES: * Calcineurin acts as an intranuclear Ca2+ sensor to promote NFAT activity. * Nuclear Ca2+ in cardiac myocytes increases via IP3R2 upon Ang II stimulation. * IP3R2 expression is directly dependent on calcineurin/NFAT. PMID- 30293139 TI - Anti-CD37 targeted immunotherapy of B-Cell malignancies. AB - CD37 is a member of tetra-spanning superfamily (characterized by their four transmembrane domains). It is one of the specific proteins for normal and malignant mature B cells. Anti CD37 monoclonal antibodies are reported to improve the overall survival in CLL. These therapeutics will increase the efficacy and reduce the toxicity in patients with both newly diagnosed and relapsed and refractory disease. Recent clinical trials have shown promising outcomes for these agents, administered both as monotherapy and in combination with standard chemotherapeutics. Long-term follow-up of combination regimens has even raised the question of whether the patients with CLL could be treated with intensive chemo-immunotherapy. In the present study, CD37 is introduced as an appealing target to treat B cell malignancies. The anti-CD37 antibodies as one of the most successful therapeutics against CD37 are introduced and the clinical outcomes of their exploitation are explained. PMID- 30293141 TI - Total knee arthroplasty in Italy: reflections from the last fifteen years and projections for the next thirty. AB - PURPOSE: Annual rates of knee arthroplasty are increasing in all developed countries, imposing a significant economic and organizational burden; it is crucial to forecast the future need for knee arthroplasty, to assist stakeholders in planning strategies and investments, especially in a country like Italy, with the largest proportion of elderly citizens in Europe. Few epidemiological studies have been performed worldwide to estimate the demand for future knee replacement, and a variety of methods have been proposed. METHODS: We investigated the epidemiology of knee arthroplasty performed in Italy in the last 15 years and projected incidence rates up to the year 2050, utilizing, comparing, and adapting the available methodologies. RESULTS: From 2001 to 2016, 812,639 primary TKA were performed in Italy on patients over 40. The total number of surgeries increased by 262% with an average annual growth rate of 6.6%. CONCLUSIONS: Adopting the best fitting projection method, an increase of 45% in incidence rate is expected for 2050. PMID- 30293143 TI - How neuraxial labor analgesia differs by approach: dural puncture epidural as a novel option. AB - BACKGROUND AND AIM: Neuraxial analgesia techniques are not limited to just standard epidural and CSE blocks. A novel approach called dural puncture epidural (DPE) which is a modification of CSE in terms of practice has gained popularity after its description and use in the obstetric population. The aim of this review is to address the practice of DPE technique as a novel option by reviewing its benefits as well as side and/or adverse effects and to understand how neuraxial labor analgesia differs by approach based on the information available in the current literature DISCUSSION: Despite controversies and concerns, more rapid onset of analgesia, early bilateral sacral analgesia, lower incidence of asymmetric block and fewer maternal and fetal side effects are provided with DPE when compared to epidural. CONCLUSION: DPE offers a favorable risk-benefit ratio for management of neuraxial analgesia as a novel option. PMID- 30293144 TI - Uses of the Past: History as a Resource for the Present. AB - Collective memory has become an increasingly important topic in social and human sciences over the past thirty years. Beyond the interest for how we understand history, collective memory research has explored how the past has been used to defend certain understandings of the world (for instance nationalist ideologies), political actions (as in the case of intractable conflicts), or collective identities (particularly when they are seen as reflecting the historical 'essence' of a national group). That is, how the history is used as a resource for the present. However, theoretical conceptualisations have more directly focused on how collective memory is produced, and less so on how it is mobilised for the present. In this paper, we propose to review the main conceptualisation of collective memory in psychology - as social thinking, as social identity, and as sense-making - and how they more or less implicitly understand the relations between past and present. In a final section, we argue that representations of history have mainly been seen, in collective memory research, as a source of meaning for the present or as a way to position oneself in the current social field. In conclusion, we propose a third way of understanding the relations between past and present, considering collective memory to be both transformative of the present and prospective for the future. PMID- 30293145 TI - Plain radiograghs of lumbar spine in patients with low back pain. AB - : Low back pain (LBP) is a common presenting complaint in our hospital in Enugu Nigeria. Three hundred thirty-three radiographs of patients with LBP were studied. A lot of them had bony outgrowths (osteophytes) on the spine. Plain radiograph of the spine is useful in studying these patients' condition. INTRODUCTION: Low back pain (LBP) is one of the common symptoms which bring patients to hospital and ultimately to radiology department for medical assistance. Plain radiographs of lumbar spine are usually the initial imaging tools requested by clinicians. The objective of this study is to evaluate commonest finding in patients with LBP to guide physicians for improved management. METHODS: This work was a retrospective study. Plain films of these patients with LBP at the University of Nigeria Teaching Hospital, Enugu, were assessed by two radiologists. Findings documented and analyzed using IBM'S SPSS 22. Association was determined using chi-square with level of significance, p < 0.05. RESULTS: Total number of radiographs reviewed was 333. One hundred and eighty-three (55.0%) patients were females. Age ranged from 14 to 101 years. Mean age of 53.4 +/- 15.9 years. Disc space was normal in majority (55.3%, 184/333) of patients; narrowing was observed in most others (43.2%, 144/333), about half of the narrowing occurring along with vacuum phenomenon. Osteophytes were commonest finding in a total of 284/333 (85.3%) existing alone or in combination with other findings. Proportion of patients with osteophytes was highest in sixth to eighth decade of life (98.8% of 61-80 age group), followed by 41-60 age group (92.9%). This association between age group and the presence of osteophytes was statistically significant (p < 0.000). Anterior vertebral body was affected in 85.0% (284/333) of patients. CONCLUSIONS: Osteophytes are common radiologic features in LBP. Anterior vertebral body is most affected. It is commoner in the older age group. Plain radiograph is an invaluable imaging tool in the management of LBP in this part of the world. PMID- 30293142 TI - Angiotensin II-mediated suppression of synaptic proteins in mouse hippocampal neuronal HT22 cell was inhibited by propofol: role of calcium signaling pathway. AB - PURPOSE: Angiotensin II (Ang II) has been shown to be involved in neurological disorders. Propofol demonstrated neuroprotective effects in neurons. METHODS: Mouse hippocampal HT22 cells were pre-treated with propofol, followed by Ang II treatment. The expression of synaptic proteins (synapsin I and PSD95) was examined. The effects of propofol on Ang II-induced NADPH oxidase expression and superoxide anion generation were examined. The effects of propofol on intracellular calcium concentration, the activation of calcium/calmodulin dependent protein kinase II (CaMKII), and protein kinase C (PKC) were measured. RESULTS: Ang II reduced the expression of synapsin I and PSD95, which was attenuated by propofol. Ang II-induced effects were blocked by Ang II type 1 receptor (AT1 receptor) blocker. Ang II induced the expression of NADPH oxidase and caused superoxide anion accumulation, which were attenuated by propofol. In addition, propofol induced intracellular calcium concentration, and activated CaMKII as well as PKCbeta. Importantly, the Ang II-mediated effects were diminished by alpha-tocopherol, and the propofol-mediated effects were alleviated by calcium chelator, CaMKII inhibitor, and PKCbeta inhibitor. CONCLUSION: Ang II, via AT1 receptor, induced oxidative stress and reduced the expression of synapsin I and PSD95 in HT22 cells. Propofol may increase synapsin I and PSD95 expression by inhibiting oxidative stress and stimulating calcium signaling pathway. PMID- 30293146 TI - The non-visualized appendix and secondary signs on ultrasound for pediatric appendicitis in the community hospital setting. AB - BACKGROUND: Secondary signs of appendicitis on ultrasound may aid with diagnosis in the setting of a non-visualized appendix (NVA). This role has not been shown in the community hospital setting. MATERIALS AND METHODS: All right lower quadrant ultrasounds performed in children for clinical suspicion of appendicitis over a 5-year period in a single community hospital were evaluated. Secondary signs of inflammation including free fluid, ileus, fat stranding, abscess, and lymphadenopathy were documented. Patients were followed for 1 year for the primary outcome of appendicitis. These data were analyzed to determine the utility of secondary signs in the diagnosis of acute appendicitis when an NVA is reported. RESULTS: Six hundred and seventeen ultrasounds were reviewed; 470 of these had an NVA. Of NVAs, 47 (10%) of patients were diagnosed with appendicitis. Sensitivity and specificity of having at least one secondary were 38.3% and 80%, respectively. The positive and negative predictive values of having at least one secondary sign were 17.3% and 92%, respectively. CONCLUSION: These data suggest that the absence of secondary signs has a strong negative predictive value for appendicitis in the community hospital setting; however, the full utility of secondary signs may be limited in this setting.

PMID- 30293140 TI - Postoperative ileus concealing intra-abdominal complications in enhanced recovery programs-a retrospective analysis of the GRACE database. AB - PURPOSE: Postoperative ileus (POI) occurrence within enhanced recovery programs (ERPs) has decreased. Also, intra-abdominal complications (IAC) such as anastomotic leakage (AL) generally present late. The aim was to characterize the link between POI and the other complications occurring after surgery. METHODS: This retrospective analysis of a prospective database was conducted by the Francophone Group for Enhanced Recovery after Surgery. POI was considered to be present if gastrointestinal functions had not been recovered within 3 days following surgery or if a nasogastric tube replacement was required. RESULTS: Of the 2773 patients who took part in the study, 2335 underwent colorectal resections (83.8%) for cancer, benign tumors, inflammatory bowel disease, and diverticulosis. Among the 2335 patients, 309 (13.2%) experienced POI, including 185 (59.9%) cases of secondary POI. Adjusted for well-known risk factors (male gender, need for stoma, right hemicolectomy, surgery duration, laparotomy, and conversion to open surgery), POI was associated with abdominal complications (OR = 4.55; 95% confidence interval (CI): 3.30-6.28), urinary retention (OR = 1.75; 95% CI: 1.05-2.92), pulmonary complications (OR = 4.55; 95% CI: 2.04-9.97), and cardiological complications (OR = 3.01; 95% CI: 1.15-8.02). Among the abdominal complications, AL and IAC were most strongly associated with POI (respectively, OR = 5.97; 95% CI: 3.74-8.88 and OR = 5.76; 95% CI: 3.56-10.62). CONCLUSION: Within ERPs, POI should not be considered as usual. There is a significant link between POI and IAC. Since POI is an early-onset clinical sign, its occurrence should alert the physician and prompt them to consider performing CT scans in order to investigate other potential morbidities. PMID- 30293147 TI - Use of Physical Activity Monitors in Rheumatic Populations. AB - PURPOSE OF REVIEW: The purpose of this review paper is to provide an overview of the recent research using physical activity monitors in rheumatic populations including those with osteoarthritis, rheumatoid arthritis, systemic lupus erythematosus, and fibromyalgia. RECENT FINDINGS: Recent research demonstrates increased use of physical activity monitors in these populations, especially in those with osteoarthritis. Results from cross-sectional, longitudinal, and intervention studies highlight that physical activity levels are below recommended guidelines, yet evidence suggests benefits such as improving pain, fatigue, function, and overall well-being. While the use of physical activity monitors in rheumatic populations is increasing, more research is needed to better understand physical activity levels in these populations, the effects of activity on relevant clinical outcomes, and how monitors can be used to help more individuals reach physical activity guidelines. PMID- 30293149 TI - "Familial venoms": a thallium intoxication cluster. PMID- 30293150 TI - Identification and characterization of the 4-epimerase AglW from the archaeon Methanococcus maripaludis. AB - Archaea are ubiquitous single-cell microorganisms that have often adapted to harsh conditions and play important roles in biogeochemical cycles with potential applications in biotechnology. Methanococcus maripaludis, a methane-producing archaeon, is motile through multiple archaella on its cell surface. The major structural proteins (archaellins) of the archaellum are glycoproteins, modified with N-linked tetrasaccharides that are essential for the proper assembly and function of archaella. The aglW gene, encoding the putative 4-epimerase AglW, plays a key role in the synthesis of the tetrasaccharide. The goal of our work was to biochemically demonstrate the 4-epimerase activity of AglW, and to develop assays to determine its substrate specificity and properties. We carried out assays using UDP-Galactose, UDP-Glucose, UDP-N-acetylglucosamine, UDP-N acetylgalactosamine and N-acetylglucosamine/N-acetylgalactosamine-diphosphate - lipid as substrates, coupled with specific glycosyltransferases. We showed that AglW has a broad specificity towards UDP-sugars and that Tyr151 within a conserved YxxxK sequon is essential for the 4-epimerase function of AglW. The glycosyltransferase-coupled assays are generally useful for the identification and specificity studies of novel 4-epimerases. PMID- 30293151 TI - Propiconazole is an activator of AHR and causes concentration additive effects with an established AHR ligand. AB - Consumers are exposed to pesticide residues and other food contaminants via the diet. Both can exert adverse effects on different target organs via the activation of nuclear receptor pathways. Hepatotoxic effects of the widely used triazole fungicide propiconazole (Pi) are generally attributed to the activation of the constitutive androstane receptor (CAR) or the pregnane X receptor (PXR). We now investigated the effects of Pi on the aryl hydrocarbon receptor (AHR) and possible mixture toxicity when Pi is present in combination with BbF, an AHR ligand. In silico docking simulations indicate that Pi can bind to human AHR. Subsequent dual luciferase reporter gene assays in human HepG2 cells showed that Pi activates the AHR in vitro. This concentration-dependent activation was confirmed by real-time RT-PCR analyses of the model AHR target genes CYP1A1 and CYP1A2 in human HepaRG and HepG2 cells. In addition, induction of CYP1A1 protein levels and enzyme activity were recorded. Similarly, increased mRNA expression and enzyme activity of Cyp1a1 and Cyp1a2 was observed in livers of rats treated with Pi for 28 days via the diet. Gene expression analysis in AHR-knockout HepaRG cells showed no induction of CYP1A1 and CYP1A2, whereas gene expression in CAR-, and PXR-knockout cells was induced. Finally, mixture effects of Pi and BbF were analyzed in human cell lines: modeling of concentration-response curves revealed concentration additivity. In conclusion, our results demonstrate that the triazole Pi is an activator of AHR in silico, in vitro and in vivo and causes additive effects with an established AHR ligand. PMID- 30293152 TI - Detection of Babesia gibsoni in dogs by combining recombinase polymerase amplification (RPA) with lateral flow (LF) dipstick. AB - Babesia gibsoni is a protozoan parasite responsible for the majority of reported cases of canine babesiosis in China. Currently, microscopic examination of the Giemsa-stained thin blood smears is the main diagnosis method in clinic. Here, we report the recombinase polymerase amplification-lateral flow (LF-RPA) dipstick detection method for targeting B. gibsoni cytochrome c oxidase subunit I (cox I) gene. The reaction takes only 20-30 min under isothermal temperatures between 30 and 45 degrees C. Specificity was evaluated using DNA from related apicomplexan parasites and their host, while the sensitivity was calculated based on the DNA from the experimental B. gibsoni-infected dogs. Results indicated that the LF-RPA method is 20 times more sensitive than the conventional PCR based on 18S rRNA and has no cross reaction with any other test DNAs. The applicability of the LF-RPA method was further evaluated using 15 samples collected from clinic. Thirteen of the 15 samples (86.67%) were detected as positive by LF-RPA, while 10 of them (66.67%) were found positive by conventional PCR. Overall, the novel LF-RPA assay is effective for the detection of B. gobsini and has considerable advantages over the conventional PCR in sensitivity, specificity, simplicity in operation, less time consumption, and visual detection. The LF-RPA method may facilitate the surveillance and early detection of B. gibsoni infection in dogs. PMID- 30293154 TI - I have back pain! PMID- 30293153 TI - Incorporating EBO-HSIC with SVM for Gene Selection Associated with Cervical Cancer Classification. AB - Microarray technology is utilized by the biologists, in order to compute the expression levels of thousands of genes. Cervical cancer classification utilizing gene expression data depends upon conventional supervised learning methods, wherein only labeled data could be used for learning. The previous methodologies had problem with appropriate feature selection as well as accurateness of classification outcomes. So, the entire performance of the cancer classification is decreased meaningfully. With the aim of overcoming the aforesaid problems, Enhanced Bat Optimization Algorithm with Hilbert-Schmidt Independence Criterion (EBO-HSIC) and Support Vector Machine (SVM) algorithm is presented in this research for identifying the specific genes from the gene expression dataset that belongs to cancer microarray. This proposed system contains phases of instance normalization, module detection, gene selection and classification. By Fuzzy C Means (FCM) algorithm, the normalization is performed for eliminating the inappropriate features from the gene dataset. Meanwhile, for effective feature selection, the EBO algorithm is used for producing more appropriate features via improved objective function values. For determining a subset of the most informative genes utilizing a rapid as well as scalable bat algorithm, this proposed method focuses on measuring the dependence amid Differentially Expressed Genes (DEGs) as well as the gene significance. The algorithm is dependent upon the HSIC and was partially enthused by EBO. With the help of SVM classifier, these gene features are categorized very precisely. Experimentation outcomes demonstrate that the presented EBO with SVM algorithm confirms a clear-cut classification performance for the given gene expression datasets. Hence the result provides higher performance by launching EBO with SVM algorithm to obtain greater accuracy, recall, precision, f-measure and less time complexity more willingly than the previous techniques. PMID- 30293156 TI - Protracted febrile myalgia as a challenging manifestation of familial Mediterranean fever: case-based review. AB - Protracted febrile myalgia syndrome (PFMS) in familial Mediterranean fever (FMF) patients is a vasculitic condition characterized by severe myalgia, fever, abdominal pain, diarrhea, and arthralgia/arthritis episodes lasting 4-6 weeks. Symptoms typically resolve with corticosteroid treatment. However, in recent years, corticosteroid-resistant PFMS patients have been reported. We herein report five pediatric FMF patients complicated with PFMS. In addition, demographic findings, Mediterranean fever (MEFV) gene analysis, symptoms at disease onset, time interval between the diagnoses of FMF and PFMS, co-existent diseases, and treatment responses were evaluated. Resolution of all PFMS symptoms was accepted as complete response, while decreased symptoms without full recovery as partial response. We searched PubMed using the keywords 'protracted febrile myalgia' and 'anakinra', and reviewed the literature. There were three male and two female patients. Median age at the diagnosis of FMF was 6 (3-10) years. The time from diagnosis of FMF to the development of PFMS was changed from 0 to 8 (median: 2) years. All of the patients, except one, had homozygous M694V mutation. All patients were treated with corticosteroids and non-steroidal anti inflammatory drugs (NSAIDs) first. Two out of five patients were exhibited partial response, while others exhibited complete response. Patients with partial response to the conventional therapies were treated with anakinra, and achieved a great response after the first dose. Anti-interleukin-1 (IL-1) therapy may be a beneficial and a reasonable treatment option, when there is insufficient response to NSAID and corticosteroid therapies in pediatric PFMS patients. PMID- 30293155 TI - Discordance of global assessment by patients and physicians is higher in osteoarthritis than in rheumatoid arthritis: a cross-sectional study from routine care. AB - The study compares patient-physician discordance in global assessment in patients with osteoarthritis (OA) versus patients with rheumatoid arthritis (RA) seen in routine care. This is a cross-sectional study conducted at an academic rheumatology center at which all patients are asked to complete a Multi Dimensional Health Assessment Questionnaire (MDHAQ), which includes a patient global assessment (PATGL). Rheumatologists are encouraged to complete a physician questionnaire, which includes a physician global assessment (DOCGL). Patients with either OA or RA were identified using ICD9 codes and classified as positive discordance (PATGL-DOCGL >= 2), negative discordance (PATGL-DOCGL<= - 2), and concordance (absolute difference between the two assessments < 2). Discordance was assessed by diagnosis. Agreement between patient and physician global assessments was evaluated using intraclass correlations. Logistic regression was performed to identify explanatory variables for positive discordance. The analysis included 243 OA and 216 RA patients. Mean PATGL was higher in OA versus RA (5.4 versus 4.2, p = 0.005), while mean DOCGL was similar (4.0 versus 3.8, p = 0.23) leading to a higher patient-physician discordance in OA (1.35 versus 0.43, p < 0.001). Positive discordance occurred in 34% of OA versus 18% of RA patients (p < 0.001). Intraclass correlation coefficients were 0.43 in OA versus 0.60 in RA patients. In logistic regressions, pain was the only statistically significant explanatory variable for discordance in both OA (OR 1.34, 95% CI 1.12-1.78) and RA (OR 1.47 95% CI 1.04-2.07). Patients with OA are more likely to be discordant with their rheumatologists than patients with RA because of a higher PATGL. Similarly to RA, the most important explanatory variable for discordance was higher pain. PMID- 30293157 TI - Etanercept-induced Crohn's disease in ankylosing spondylitis: a case report and review of the literature. AB - Tumor necrosis factor (TNF)-alpha is a cytokine that plays a well-established, key role as a central mediator of inflammation and immune regulation. TNF-alpha and its receptors are suggested to play a critical role in a number of chronic inflammatory diseases, including rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis (AS), juvenile chronic arthritis, and inflammatory bowel disease (IBD). TNF-alpha inhibitors are currently used in the treatment of these diseases. We report a 29-year-old male with AS who developed Crohn's disease while taking etanercept. Etanercept treatment was interrupted and a switch to a monoclonal antibody-based anti-TNF treatment using adalimumab was started, which induced a prompt improvement of the gastrointestinal symptoms. We indicate the immunodysregulatory and proinflammatory effects of etanercept and discuss the potential pathogenic mechanisms of the paradoxical effect of TNF-alpha inhibitors. We also review the related literature on new-onset IBD following anti TNF treatment for AS. PMID- 30293158 TI - Spinal cord stimulation modulates descending pain inhibition and temporal summation of pricking pain in patients with neuropathic pain. AB - BACKGROUND: Spinal cord stimulation (SCS) is an established treatment option for patients with refractory chronic pain conditions. While effects of SCS on dorsal horn neuronal circuitries are intensively studied, current knowledge on the impact of SCS on descending pain pathways is scarce and relies on preclinical data. We aimed to address this topic and hypothesized a significant effect of SCS on descending pain modulation. In light of current efforts to determine the sensitivity of "static" versus "dynamic" somatosensory parameters to characterize pathophysiological pain conditions, all SCS patients were carefully investigated using both classes of somatosensory outcome parameters. METHODS: Descending pain pathways were investigated by using a "Cold Pressor Test." This test enables to evaluate the efficacy of conditioned pain modulation (CPM) at the individual level. CPM efficacy was assessed in eight neuropathic pain patients (age 55.5 +/- 10.6) during the two conditions stimulator "ON" and "OFF." The impact of SCS on "static" and "dynamic" somatosensory parameters was explored by using a quantitative sensory testing (QST) battery. RESULTS: CPM efficacy on pressure pain sensitivity was nearly absent during "OFF" (- 1.2 +/- 5.6% facilitation), but increased significantly to 16.3 +/- 3.4% inhibition during "ON" (p = 0.03). While most "static" nociceptive QST parameters, represented by mechanical/thermal pain thresholds, exhibited only small effects of SCS (p > 0.05), the wind-up ratio was strongly reduced to within the normal range during "ON" (p = 0.04; Cohen's d = 1.0). Dynamic mechanical allodynia was abolished in six of seven patients. CONCLUSIONS: Our study provides first human evidence for an impact of SCS on descending pain pathways in the dorsolateral funiculus and emphasizes the significance of "dynamic" pain measures like "CPM"-efficacy and "temporal summation" to evaluate SCS treatment effects. Future prospective studies may use these measures of nociceptive processing to predict SCS therapy response.

PMID- 30293161 TI - Interactions between polycyclic aromatic hydrocarbons and epoxide hydrolase 1 play roles in asthma. AB - Asthma, as one of the most common chronic diseases in children and adults, is a consequence of complex gene-environment interactions. Polycyclic aromatic hydrocarbons (PAHs), as a group of widespread environmental organic pollutants, are involved in the development, triggering and pathologic changes of asthma. Various previous studies reported the critical roles of PAHs in immune changes, oxidative stress and environment-gene interactions of asthma. EPHX1 (the gene of epoxide hydrolase 1, an enzyme mediating human PAH metabolism) had a possible association with asthma by influencing PAH metabolism. This review summarized that (1) the roles of PAHs in asthma-work as risk factors; (2) the possible mechanisms involved in PAH-related asthma-through immunologic and oxidative stress changes; (3) the interactions between PAHs and EPHX1 involved in asthma enzymatic activity of epoxide hydrolase 1, which affected by EPHX1 genotypes/SNPs/diplotypes, could influence human PAH metabolism and people's vulnerability to PAH exposure. This review provided a better understanding of the above interactions and underlying mechanisms for asthma which help to raise public's concern on PAH control and develop strategies for individual asthma primary prevention. PMID- 30293160 TI - Wearable Sensors to Monitor, Enable Feedback, and Measure Outcomes of Activity and Practice. AB - PURPOSE OF REVIEW: Measurements obtained during real-world activity by wearable motion sensors may contribute more naturalistic accounts of clinically meaningful changes in impairment, activity, and participation during neurologic rehabilitation, but obstacles persist. Here we review the basics of wearable sensors, the use of existing systems for neurological and rehabilitation applications and their limitations, and strategies for future use. RECENT FINDINGS: Commercial activity-recognition software and wearable motion sensors for community monitoring primarily calculate steps and sedentary time. Accuracy declines as walking speed slows below 0.8 m/s, less so if worn on the foot or ankle. Upper-extremity sensing is mostly limited to simple inertial activity counts. Research software and activity-recognition algorithms are beginning to provide ground truth about gait cycle variables and reveal purposeful arm actions. Increasingly, clinicians can incorporate inertial and other motion signals to monitor exercise, activities of daily living, and the practice of specific skills, as well as provide tailored feedback to encourage self management of rehabilitation. Efforts are growing to create a compatible collection of clinically relevant sensor applications that capture the type, quantity, and quality of everyday activity and practice in known contexts. Such data would offer more ecologically sound measurement tools, while enabling clinicians to monitor and support remote physical therapies and behavioral modification when combined with telemedicine outreach. PMID- 30293162 TI - Cranioplasty following decompressive craniectomy: minor surgical complexity but still high periprocedural complication rates. AB - Cranioplasty following decompressive craniectomy is of low surgical complexity, so much so that it has become the "beginners" cranial case. However, these "simple" procedures may have high complication rates. Identification of specific risk factors would allow targeted intervention to lower the complication rates. The aim of this study was to assess the rate of complications and to evaluate potential risk factors. We conducted a review of all patients who underwent cranioplasty in our center following decompressive craniectomy for stroke or brain trauma between 2009 and 2016. One hundred fifty-two patients were identified. Fifty-three percent were male. Mean age was 48 (range 11-78). Median time from craniectomy until cranioplasty was 102 days (range 14-378). The overall rate of complications, such as postoperative bleeding, seizures, postoperative infection, and hydrocephalus, was 30%. The mortality rate was 1%. None of the following potential risk factors was associated with significantly increased risk of periprocedural complications: gender (p = 0.34), age (p = 0.39), cause of initial surgery (p = 0.08), duration of surgery (p = 0.59), time of surgery (0.24), surgical experience (p = 0.17), and time from craniectomy until cranioplasty (p = 0.27). The 30-day complication rate following cranioplasty is high, but serious permanent deficits from these complications were rare. We found no clear predictor for these 30-day complications, which renders its prevention difficult.

AB - Post-thrombotic syndrome (PTS) is the most common chronic complication of deep vein thrombosis (DVT). Identifying high-risk patients for the development of PTS might be useful for its prevention. The COMMAND VTE Registry is a multicenter registry that enrolled 3027 consecutive patients with acute symptomatic venous thromboembolisms (VTEs) in Japan between January 2010 and August 2014. The current study population consisted of 1298 patients with lower extremities DVTs who completed 3-year follow-up for those who developed PTS and those without PTS. We investigated risk factors for the development of PTS at the time of DVT diagnosis, using a multivariable logistic regression analysis. Of the entire 1298 study patients, 169 (13%) patients were diagnosed with PTS within 3 years. The rate for anticoagulation discontinuation during follow-up was not significantly different between those with and without PTS. Chronic kidney disease (OR 2.21, 95% CI 1.45-3.39, P < 0.001), leg swelling (OR 4.15, 95% CI 2.25-7.66, P < 0.001), absence of transient risk factors for VTEs (OR 2.39, 95% CI 1.55-3.67, P < 0.001), active cancer (OR 3.66, 95% CI 2.30-5.84, P < 0.001), and thrombophilia (OR 2.07, 95% CI 1.06-4.04, P = 0.03) were independent risk factors for the development of PTS. In this real-world Japanese DVT registry, we could identify several important risk factors for the development of PTS at the time of DVT diagnosis.

AB - The topic of interstitial cystitis (IC), also known as painful bladder syndrome (PBS), and folate/one carbon metabolism has previously been unaddressed in research. This narrative review highlights a potential connection for those with mast cell-related IC and histamine-mediated pain that is explored through four conceptual sections. The first section focuses on the nature of mast cell involvement and histamine-mediated pain in some interstitial cystitis patients. The second section reviews the literature on folate status in wider allergic conditions. The third section addresses the role of folate and methylation in general in histamine excretion. Finally, folate metabolism and vascular function are addressed because of the vascular abnormalities present in some IC bladders. PMID- 30293166 TI - A randomized controlled trial comparing two voiding trials after midurethral sling with or without colporrhaphy. AB - INTRODUCTION AND HYPOTHESIS: To compare the force of the stream (FOS) voiding trial with the standard voiding trial (SVT) after outpatient midurethral sling (MUS) whether or not colporrhaphy was performed. METHODS: This is a randomized controlled non-inferiority trial of patients scheduled for MUS or colporrhaphy. Sample size of 102 patients was calculated for 80% power. Patients were randomized to FOS or SVT. Primary outcome was the number of unexpected postoperative visits (UPOVs) for voiding dysfunction (VD) or urinary tract infection (UTI). Voiding dysfunction was defined as urinary retention or post void residual (PVR) > 200 cc. Subjects rated FOS using a visual analog scale (VAS). Criterion for non-inferiority was an upper limit of < 10% for the 95% CI. Analyses were performed using SAS version 9.4 (SAS Institute. Cary, NC). RESULTS: One hundred two subjects were included (49 FOS, 53 SVT). Immediate postoperative catheterization for FOS and SVT was 8.2% (n = 4) and 9.4% (n = 5), respectively. Recovery time was significantly less for FOS versus SVT (p = 0.0002). Total UPOVs were five (10.2%) and two (3.8%) for FOS and SVT, respectively. Two FOS subjects who had MUS + colporrhaphy passed their VT and had subsequent UPOVs for VD. No evidence of non-inferiority was noted when comparing FOS to SVT for total UPOVs: CI: 6.0% (-5.2, 17.2) for postoperative VD [CI: 6.1% (-4.0, 16.2)] or UTIs [CI: 0.3% (-9.4, 10.1)]. CONCLUSIONS: No evidence of non-inferiority was noted comparing FOS with SVT for unexpected postoperative visits for voiding dysfunction or UTI. This study shows the need for larger studies to assess the use of the FOS method in patients undergoing surgery for prolapse with or without MUS. PMID- 30293167 TI - Risk of new-onset urinary incontinence 3 and 12 months after vaginal or cesarean delivery of twins: Part I. AB - INTRODUCTION AND HYPOTHESIS: Our purpose was to compare the prevalence of urinary incontinence (UI) 3 and 12 months after vaginal vs cesarean delivery of twins after 34 weeks of gestation. METHODS: This was a multicenter prospective cohort study conducted at 172 French maternity units and included 2812 primiparous women with twins with no prior history of UI. Participants were enrolled at the time of delivery and followed up to 12 months postpartum. The primary outcome was the prevalence of UI, both stress and urge, 3 months postpartum, based on the patient reporting any frequency of urine leakage to the first question of the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF). The Pelvic Floor Distress Inventory - Short Form 20 (PFDI-20), Pelvic Floor Impact Questionnaire - Short Form 7 (PFIQ-7), Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12), and Medical Outcome Study Short Form 12 (SF-12) were also used. RESULTS: The ICIQ-SF was completed by 1155 (39.8%) and 800 (27.5%) women, respectively, at 3 and 12 months postpartum; 556 (48%) had delivered vaginally and 599 (52%) by cesarean section. The prevalence of UI at 3 months was 26% overall and was significantly higher in the vaginal delivery group at both 3 months (35% vs 17% in the cesarean group, p < 0.0001) and 12 months postpartum (38% vs 24%, p < 0.0001). UI was predominantly stress or mixed. The risk factors for UI at 3 months, determined by multivariate modeling, were vaginal delivery [odds ratio (OR) 3.073, 95% confidence interval (CI) 2.3-4.105, p < 0.0001) and body mass index >25 in early pregnancy (OR 1.620, 95% CI 1.188 2.209, p = 0.0023). CONCLUSIONS: Vaginal delivery is a risk factor for UI at 3 months after twin birth. PMID- 30293168 TI - Complete labial fusion in a postmenopausal woman: unusual cause of urinary symptoms.

AB - Nutritional scarcity during summer and winter is a major constraint for sheep rearing in the semi-arid tropical region. In this region, a new crossbred sheep has been developed by the crossing of a native sheep breed Malpura with a breed of hot-humid coastal region breed Garole. A study was conducted for 9 weeks to assess the physiological response of crossbred (Garole x Malpura x Malpura, GMM) rams under nutritional scarcity in the semi-arid tropical region. Eighteen adult crossbred rams were randomly allocated into three groups of six animals each. The groups are G1 (control, ad libitum feeding), G2 (20% less than ad libitum feeding), and G3 (30% less than ad libitum feeding). The animals were stall-fed with a diet consisting of 70% roughage (Cenchrus ciliaris hay) and 30% concentrate feed. Body weight gain, average daily gain, and feed intake were significantly (P < 0.05) lower in G2 and G3 as compared to G1 rams. Water intake was significantly (P < 0.05) higher in G2 and G3. Physiological responses, blood biochemical and endocrine profile did not differ between the groups. The results indicate that the crossbred rams evolved through the crossing of the hot semi arid tropical region breed with hot humid coastal region breed are able to maintain their body homeostasis despite nutritional scarcity although their body weight decreased. PMID- 30293170 TI - Velocity Curvature Index: a Novel Diagnostic Biomarker for Large Vessel Occlusion. AB - Despite being a conveniently portable technology for stroke assessment, Transcranial Doppler ultrasound (TCD) remains widely underutilized due to complex training requirements necessary to reliably obtain and interpret cerebral blood flow velocity (CBFV) waveforms. The validation of objective TCD metrics for large vessel occlusion (LVO) represents a first critical step toward enabling use by less formally trained personnel. In this work, we assess the diagnostic utility, relative to current standard CT angiography (CTA), of a novel TCD-derived biomarker for detecting LVO. Patients admitted to the hospital with stroke symptoms underwent TCD screening and were grouped into LVO and control groups based on the presence of CTA confirmed occlusion. Velocity curvature index (VCI) was computed from CBFV waveforms recorded at multiple depths from the middle cerebral arteries (MCA) of both cerebral hemispheres. VCI was assessed for 66 patients, 33 of which had occlusions of the MCA or internal carotid artery. Our results show that VCI was more informative when measured from the cerebral hemisphere ipsilateral to the site of occlusion relative to contralateral. Moreover, given any pair of bilateral recordings, VCI separated LVO patients from controls with average area under receiver operating characteristic curve of 92%, which improved to greater than 94% when pairs were selected by maximal velocity. We conclude that VCI is an analytically valid candidate biomarker for LVO diagnosis, possessing comparable accuracy, and several important advantages, relative to current TCD diagnostic methodologies. PMID- 30293172 TI - Tactile sensor-based real-time clustering for tissue differentiation. AB - PURPOSE: Reliable intraoperative delineation of tumor from healthy brain tissue is essentially based on the neurosurgeon's visual aspect and tactile impression of the considered tissue, which is-due to inherent low brain consistency contrast a challenging task. Development of an intelligent artificial intraoperative tactile perception will be a relevant task to improve the safety during surgery, especially when-as for neuroendoscopy-tactile perception will be damped or-as for surgical robotic applications-will not be a priori existent. Here, we present the enhancements and the evaluation of a tactile sensor based on the use of a piezoelectric tactile sensor. METHODS: A robotic-driven piezoelectric bimorph sensor was excited using multisine to obtain the frequency response function of the contact between the sensor and fresh ex vivo porcine tissue probes. Based on load-depth, relaxation and creep response tests, viscoelastic parameters E1 and E2 for the elastic moduli and eta for the viscosity coefficient have been obtained allowing tissue classification. Data analysis was performed by a multivariate cluster algorithm. RESULTS: Cluster algorithm assigned five clusters for the assignment of white matter, basal ganglia and thalamus probes. Basal ganglia and white matter have been assigned to a common cluster, revealing a less discriminatory power for these tissue types, whereas thalamus was exclusively delineated; gray matter could even be separated in subclusters. CONCLUSIONS: Bimorph-based, multisine-excited tactile sensors reveal a high sensitivity in ex vivo tissue-type differentiation. Although, the sensor principle has to be further evaluated, these data are promising. PMID- 30293171 TI - Measuring relative vibrotactile spatial acuity: effects of tactor type, anchor points and tactile anisotropy. AB - Vibrotactile displays can compensate for the loss of sensory function of people with permanent or temporary deficiencies in vision, hearing, or balance, and can augment the immersive experience in virtual environments for entertainment, or professional training. This wide range of potential applications highlights the need for research on the basic psychophysics of mechanisms underlying human vibrotactile perception. One key consideration when designing tactile displays is determining the minimal possible spacing between tactile motors (tactors), by empirically assessing the maximal throughput of the skin, or, in other words, vibrotactile spatial acuity. Notably, such estimates may vary by tactor type. We assessed vibrotactile spatial acuity in the lower thoracic region for three different tactor types, each mounted in a 4 * 4 array with center-to-center inter tactor distances of 25 mm, 20 mm, and 10 mm. Seventeen participants performed a relative three-alternative forced-choice point localization task with successive tactor activation for both vertical and horizontal stimulus presentation. The results demonstrate that specific tactor characteristics (frequency, acceleration, contact area) significantly affect spatial acuity measurements, highlighting that the results of spatial acuity measurements may only apply to the specific tactors tested. Furthermore, our results reveal an anisotropy in vibrotactile perception, with higher spatial acuity for horizontal than for vertical stimulus presentation. The findings allow better understanding of vibrotactile spatial acuity and can be used for formulating guidelines for the design of tactile displays, such as regarding inter-tactor spacing, choice of tactor type, and direction of stimulus presentation. PMID- 30293173 TI - Virtual downsizing for decision support in mitral valve repair. AB - PURPOSE: Various options are available for the treatment of mitral valve insufficiency, including reconstructive approaches such as annulus correction through ring implants. The correct choice of general therapy and implant is relevant for an optimal outcome. Additional to guidelines, decision support systems (DSS) can provide decision aid by means of virtual intervention planning and predictive simulations. Our approach on virtual downsizing is one of the virtual intervention tools that are part of the DSS workflow. It allows for emulating a ring implantation based on patient-specific lumen geometry and vendor specific implants. METHODS: Our approach is fully automatic and relies on a lumen mask and an annulus contour as inputs. Both are acquired from previous DSS workflow steps. A virtual surface- and contour-based model of a vendor-specific ring design (26-40 mm) is generated. For each case, the ring geometry is positioned with respect to the original, patient-specific annulus and additional anatomical landmarks. The lumen mesh is parameterized to allow for a vertex-based deformation with respect to the user-defined annulus. Derived from post interventional observations, specific deformation schemes are applied to atrium and ventricle and the lumen mesh is altered with respect to the ring location. RESULTS: For quantitative evaluation, the surface distance between the deformed lumen mesh and segmented post-operative echo lumen close to the annulus was computed for 11 datasets. The results indicate a good agreement. An arbitrary subset of six datasets was used for a qualitative evaluation of the complete lumen. Two domain experts compared the deformed lumen mesh with post interventional echo images. All deformations were deemed plausible. CONCLUSION: Our approach on virtual downsizing allows for an automatic creation of plausible lumen deformations. As it takes only a few seconds to generate results, it can be added to a virtual intervention toolset without unnecessarily increasing the pipeline complexity.

PMID- 30293175 TI - Fluorometric determination of doxycycline based on the use of carbon quantum dots incorporated into a molecularly imprinted polymer. AB - A fluorometric assay is described for doxycycline detection. It is based on the use of nitrogen-doped carbon quantum dots (NCQDs) coated with molecularly imprinted polymers (MIPs). The NCQDs were prepared by a one-step hydrothermal reaction using citric acid and ethylenediamine (EDA) as the starting materials. Afterwards, the NCQDs were incorporated into the polymer that was molecularly imprinted with doxycycline. It is found that doxycycline quenches the fluorescence of the NCQDs, and that the functional groups on the surface of NCQDs play an important role in terms of quenching efficiency. A larger fraction of carboxyl groups presented on the surface of NCQDs leads to a higher quenching efficiency due to the enhanced electron transfer from NCQD to doxycycline. The NCQDs@MIP composite can specifically and rapidly recognize doxycycline. Fluorescence drops linearly in the 5 to 50 MUM doxycycline concentration range, and the limit of detection is 87 nM. This method was successfully applied to the determination of doxycycline in spiked pig serum where it gave recovery rates of >94%. Graphical abstract Schematic illustration for fabricating a fluorescent sensor based on nitrogen-doped carbon quantum dots (NCQDs) and molecularly imprinted polymers (MIPs). The sensor integrates the merits of the high sensitivity of NCQD and good selectivity of MIPs, and can be significantly quenched upon interaction with doxycycline. PMID- 30293176 TI - Quality not quantity: loneliness subtypes, psychological trauma, and mental health in the US adult population. AB - PURPOSE: Loneliness is a recognised public-health concern that is traditionally regarded as a unidimensional construct. Theories of loneliness predict the existence of subtypes of loneliness. In this study, latent class analysis (LCA) was used to test for the presence of loneliness subtypes and to examine their association with multiple mental health variables. METHODS: A nationally representative sample of US adults (N = 1839) completed the De Jong Gierveld Loneliness Scale, along with self-report measures of childhood and adulthood trauma, psychological wellbeing, major depression, and generalized anxiety. RESULTS: When treated as a unidimensional construct, 17.1% of US adults aged 18 70 were classified as lonely. However, the LCA results identified four loneliness classes which varied quantitatively and qualitatively: 'low' (52.8%), 'social' (8.2%), 'emotional' (26.6%), and 'social and emotional' (12.4%) loneliness. The 'social and emotional' class were characterised by the highest levels of psychological distress, followed by the 'emotional' class. The 'social' loneliness class had similar mental health scores as the 'low' loneliness class. Childhood and adulthood trauma were independently related to the most distressed loneliness classes. CONCLUSIONS: Current findings provide support for the presence of subtypes of loneliness and show that they have unique associations with mental health status. Recognition of these subtypes of loneliness revealed that the number of US adults aged 18-70 experiencing loneliness was twice as high as what was estimated when loneliness was conceptualized as a unidimensional construct. The perceived quality, not the quantity, of interpersonal connections was associated with poor mental health. PMID- 30293177 TI - Mulching with coffee husk and pulp in strawberry affects edaphic predatory mite and spider mite densities. AB - Mulching of soil beds of strawberry fields is usually done with polyethylene film in southern Minas Gerais state, Brazil. This material is relatively expensive and difficult to discard after use. In some countries, mulching is done with the use of organic material that could have an advantage over the use of plastic for its easier degradation after use, and for favoring edaphic beneficial organisms. Predatory mites (especially Gamasina, Mesostigmata) may be abundant in the soil and could conceivably move to the soil surface and onto the short-growing strawberry plants at night, helping in the control or pest arthropods. The two spotted spider mite, Tetranychus urticae Koch, is considered an important strawberry pest in that region, where the fungus Neozygites floridana (Weiser and Muma) has been found to infect it. Different mulching types could affect the incidence of this pathogen. Dehydrated coffee husk and pulp (DCHP) is a byproduct readily available in southern Minas Gerais, where could be used as organic mulching in strawberry beds. The temporary contact of that material with the soil of a patch of natural vegetation could facilitate its colonization by edaphic predatory mites helpful in the control of strawberry pests. The objective of this work was to study the effect of mulching type on the population dynamics of the two-spotted spider mite, associate mites and N. floridana, in a greenhouse and in the field. The use of DCHP increased the number of edaphic Gamasina on strawberry plants-Proctolaelaps pygmaeus (Muller) (Melicharidae) and Blattisocius dentriticus (Berlese) (Blattisociidae) were observed on strawberry leaflets, mainly in nocturnal samplings, indicating their possible daily migration from soil to plants. Lower levels of two-spotted spider mite occurred on plants from pots or soil beds mulched with DCHP instead of polyethylene film, possibly because of the slightly higher levels of mites of the family Phytoseiidae and infection by N. floridana. Adding DCHP onto the floor of natural vegetation did not result in higher diversity or levels of gamasine mites on DCHP. Complementary studies should be conducted to find ways to increase diversity and density of those organisms in strawberry beds, in an attempt to improve biological control of strawberry pests. The decision to use DCHP for mulching should also take into account other factors such as strawberry yield, costs and efficiency of weed management, to be evaluated in subsequent studies. PMID- 30293178 TI - Quantitative assessment of dietary supplement intake in 77,000 French adults: impact on nutritional intake inadequacy and excessive intake. AB - BACKGROUND: Dietary supplements (DS) are largely consumed in Western countries without demonstrating their nutritional benefits and safety in the general population. The aims, in a large population-based study of French adults, were: (1) to compare the prevalence of nutrient intake inadequacy and the proportion of individuals exceeding tolerable upper intake levels (UL) between DS users and non users, and (2) to quantify the extent of potentially "at-risk" DS use practices (e.g., DS/drugs contraindicated association or use of beta-carotene DS in smokers). METHODS: 76,925 participants, 47.6% men and 52.4% women, mean age 46.9 +/- 16.3 years were enrolled to the NutriNet-Sante cohort and they completed a quantitative DS questionnaire and three 24 h dietary records. A composition database including > 8000 DS was developed. Variance reduction was applied to estimate usual intakes and analyses were weighted according to the French census data. RESULTS: Among DS users of the specific nutrient, DS contributed to 41% of total intake for vitamin D in men, 55% in women; and to 20% of total intake for pyridoxine in men, 21% in women. Compared to dietary intakes only, their prevalence of inadequacy was reduced by 11% for vitamin C, 9% for magnesium, 6% for pyridoxine in men, and 19% for calcium, 12% for iron, and 11% for magnesium in women (p < 0.0001). The proportion of subjects exceeding UL reached 6% for iron and 5% for magnesium in men, and 9% for iron in women. 6% of DS users had potentially "at-risk" practices. CONCLUSION: While DS use contributed to decrease the prevalence of insufficient intake for several nutrients, it also conveyed excessive intake of iron and magnesium. Besides, a substantial proportion of potentially "at-risk" DS use practices was reported.

AIM: To evaluate the association between duration of exclusive breastfeeding (EB) and consumption of ultra-processed foods, fruits and vegetables by Brazilian children. METHODS: This is a cross-sectional study nested in a cohort of 403 children age 4-7 years. Food consumption was evaluated by three food records and the foods were grouped by the amount of processing involved (minimal, including fruit and vegetables to ultra-processed foods). Adjusted linear and multinomial regression models were proposed to evaluate the association of EB with children's food intake. Median duration of EB was 4.0 (2.0 6.0) months and the prevalence of EB of 4 months or more was 60.9%. RESULTS: Mean energy consumption was 1536 kcal/day, 38% of energy was from ultra-processed foods. Mean intake of fruit and vegetables was 130 g/day. For each 1-month increase in duration of EB there was a 0.7% decrease in energy from ultra processed foods (beta: - 0.7; 95% CI: - 1.3 to 0.1; p = 0.038). EB of less than 4 months was associated with the child being in the lowest tercile for consumption of fruit and vegetables (Adjusted OR: 1.8; 95% CI: 1.1-3.0; p = 0.030) and the highest for consumption of ultra-processed foods (adjusted OR: 1.7; 95% CI: 1.1 2.9; p = 0.040). CONCLUSIONS: In addition to other benefits of EB, we emphasize its importance for the formation of healthy eating habits, contributing to a higher consumption of fruit and vegetables and lower consumption of ultra processed foods in childhood. PMID- 30293180 TI - Abnormal Functional Connectivity Density in Post-Stroke Aphasia. AB - Post-stroke aphasia (PSA), which refers to the loss or impairment of language, is typically caused by left hemisphere lesions. Previous neuroimaging studies have indicated that the pathology of PSA may be related to abnormalities in functional integration. In this study, we used resting-state functional magnetic resonance imaging (rs-fMRI) to examine functional connectivity density (FCD) in PSA. We compared short- and long-range FCD between individuals with PSA (n = 17) and healthy controls (HC, n = 20). We then performed Pearson's correlation analysis on the FCD values from the affected brain regions and the speech scores in the PSA group. Compared with HCs, individuals with PSA showed increased short-range FCD in the contralesional temporal gyrus, the inferior frontal gyrus, the thalamus, the insula, and the mesial temporal gyrus [hippocampus/parahippocampus (HIP/ParaHIP)]. PSA demonstrated an increased long-range FCD in the contralesional mesial temporal gyrus (HIP/ParaHIP). PSA also displayed decreased short-range FCD in the ipsilesional part of the frontal gyrus, the caudate, the thalamus, the fusiform gyrus, and the mesial temporal gyrus (HIP/ParaHIP), and decreased long-range FCD in the ipsilesional superior temporal gyrus, the fusiform gyrus, and the mesial temporal gyrus (HIP/ParaHIP). The decreased long range FCD in the left superior temporal gyrus in PSA subjects was positively correlated with the spontaneous speech score. The altered FCD observed due to disrupted functional connectivity after stroke may lead to language production, semantic processing, and cognitive impairments. Our findings expand previous functional studies on stroke and provide new evidence of the intraregional and interregional interactions at the voxel level in the pathophysiology of PSA. PMID- 30293181 TI - Greater knee flexion excursion/moment in hopping is associated with better knee function following anterior cruciate ligament reconstruction. AB - PURPOSE: Individuals with impaired knee function after anterior cruciate ligament reconstruction (ACLR) may be at greater risk of developing knee osteoarthritis related to abnormal knee joint movement and loading. The aim of this study was to assess the association between knee biomechanics and knee laxity during hopping and clinically assessed knee function (i.e., patient-reported knee function and hop tests) following ACLR. METHODS: Sixty-six participants (23 women, mean age 28 +/- 6 years, mean 18 +/- 3 months following ACLR) completed a standardized single leg hopping task. Three-dimensional movement analysis was used to assess knee flexion excursion and body weight/height normalized knee flexion moments during landing for the involved limb. Anterior-posterior knee laxity was assessed with a KT-1000 knee arthrometer. Participants then completed a patient-reported knee function questionnaire and three separate hop tests (% of uninvolved limb) and were divided into poor and satisfactory knee function groups (satisfactory: >=85% patient-reported knee function and >= 85% hop test symmetry). Associations between knee function and hop biomechanics/knee laxity were assessed using logistic regression and interquartile range scaled odds ratios (ORIQR). RESULTS: Greater knee flexion excursion (ORIQR 2.9, 95%CI 1.1-7.8), greater knee flexion moment (ORIQR 4.9, 95%CI 1.6-14.3) and lesser knee laxity (ORIQR 4.7, 95%CI 1.5 14.9) were significantly associated with greater odds of having satisfactory knee function (>= 85% patient-reported knee function and >= 85% hop test symmetry). CONCLUSION: Greater knee flexion excursion/moment during hop-landing and lesser knee laxity is associated with better patient-reported knee function and single leg hop test performance following ACLR. Patients with lower levels of knee function following ACLR demonstrated hop-landing biomechanics previously associated with early patellofemoral osteoarthritis. Therefore, interventions aimed at improving hop landing biomechanics in people with poor knee function are likely required. LEVEL OF EVIDENCE: III, Cross-sectional study. PMID- 30293182 TI - The reversed dynamic patellar apprehension test mimics anatomical complexity in lateral patellar instability. AB - PURPOSE: To develop a dynamic physical examination test that functionally simulates actual patellar instability events and that mimics the range of patellar stabilizer insufficiency in an individual patient. METHODS: Seventy eight consecutive patients (male/female 35/43; mean age 22 +/- 7 years) with recurrent lateral patellar instability and 35 controls (male/female 16/19; mean age 31 +/- 14 years) were prospectively evaluated using the reversed dynamic patellar apprehension test (ReDPAT). Anatomical predisposition was assessed according to Dejour's classification of trochlear dysplasia, tibial tuberosity trochlear groove distance, tibial tuberosity-posterior cruciate ligament distance, patellar height, and varus/valgus malalignment. RESULTS: The study group had an average of 3.4 +/- 1.0 (1-6) anatomical risk factors for lateral patellar dislocation. Severe trochlear dysplasia (84%) and patella alta (49%) were the most common. Test sensitivity and specificity was 93.7% (95% CI 0.8584 0.9791) and 88.2% (95% CI 0.7255-0.9670), respectively. The positive predictive value reached 94.9% (95% CI 0.8739-0.9859) and the negative predictive value was 85.7% (95% CI 0.6974-0.9519). The ReDPAT results became positive at a mean knee flexion angle of 58 degrees +/- 17 degrees (20 degrees -90 degrees ). Knee flexion angle correlated significantly with the severity of trochlear dysplasia (p = 0.018), valgus deformity (p = 0.011), and the total number of anatomical risk factors (p = 0.02). CONCLUSION: This study introduced the reversed dynamic patellar apprehension test as a reliable clinical examination tool in the assessment of lateral patellar instability. The results of this study indicate that the degree of knee joint flexion at which the provocative sense of apprehension becomes positive correlates with severity of trochlear dysplasia, valgus deformity and the total number of anatomical risk factors for patellar instability. This test indicates the patient-specific end of stable patellar tracking and the beginning of patellar stabilizer insufficiency. Therefore, this test might be helpful in deciding for or against a bony procedure in the treatment of patellar dislocation. LEVEL OF EVIDENCE: II. PMID- 30293183 TI - Social connectivity among female Tibetan macaques (Macaca thibetana) increases the speed of collective movements. AB - Social network analysis provides insights into patterns of group movements in primates, but fewer studies to date have focused on the dynamics of how such movements occur. In this study, we proposed and tested two hypotheses about the influence of sex on social connectivity and group movement in Tibetan macaques (Macaca thibetana): (1) adult females are socially more connected than are adult males and (2) social connectivity facilitates the speed of collective decision making. We collected data from 128 successful collective movements (>= 2 individuals followed an initiator within 5 min) over a 2-month period in a group of adult Tibetan macaques at Mt. Huangshan, China. Although high-ranking individuals of both sexes in our dataset were more central in their social network than were low-ranking individuals, our results show that affiliations between females were stronger, with more preferred associations than those between males. Groups with more females reached collective decisions faster than groups with fewer females. We conclude that female Tibetan macaques use their social networks to enhance the speed of collective decision-making, which may have associated fitness benefits. PMID- 30293184 TI - Clinical evaluation of a low-shrinkage resin composite in endodontically treated premolars: 3-year follow-up. AB - OBJECTIVES: This study compared the 3-year clinical performance of a low shrinkage silorane-based composite material with that of a methacrylate-based composite material in the restoration of endodontically treated premolar teeth. MATERIALS AND METHODS: A total of 70 patients requiring a Class II composite resin restoration of a premolar tooth following root-canal treatment participated in the study. Cavities were restored with either a silorane-based restorative (Filtek Silorane + Silorane System Adhesive) or a methacrylate-based restorative (Filtek Z250 + Clearfil SE Bond) system applied according to the manufacturer's instructions. Restorations were evaluated by two blinded observers at five different time intervals (baseline; 6 months; 1, 2, and 3 years) according to modified USPHS criteria. Pearson's chi-square tests were used to examine differences in the clinical performance of the materials (retention, color match, marginal discoloration, secondary caries, anatomical form, marginal adaptation, and surface roughness), and Friedman and Wilcoxon tests were used to compare changes between baseline and each recall time, with a level of 0.05 considered statistically significant. RESULTS: After 3 years, no statistically significant differences in clinical performance were observed between the two materials (p > 0.05). Intra-system comparisons revealed a statistically significant deterioration in color match, marginal discoloration, anatomical form, marginal adaptation, and surface roughness scores after 3 years for both systems. Although the difference was not significant at 3 years of follow-up, the level of deterioration in marginal adaptation and surface roughness was greater for the Filtek Silorane restoration than for the Filtek Z250 restoration at the 1 year follow-up (p > 0.05). CONCLUSION: Restorations of both materials were clinically acceptable after 3 years. The Filtek Silorane system did not appear to offer any clinical advantages over the methacrylate-based system when used in the restoration of Class II cavities in endodontically treated premolars. CLINICAL RELEVANCE: The restoration of endodontically treated premolars with minor or moderate loss of tooth structure can be directly performed either with silorane or methacrylate-based composite resins. PMID- 30293185 TI - Retentive force of PEEK secondary crowns on zirconia primary crowns over time. AB - OBJECTIVES: The purpose of the present study was to evaluate the retentive forces of CAD/CAM-fabricated polyetheretherketone (PEEK) secondary crowns on zirconia primary crowns over an artificial aging period representing 10 years of clinical service and compare them to electroformed secondary crowns made from pure gold. MATERIAL AND METHODS: Implant-supported zirconia primary crowns (N = 20) were CAD/CAM milled and provided either with electroformed secondary crowns (group ZE; N = 10) or CAD/CAM-fabricated PEEK secondary crowns (group ZP; N = 10). All secondary crowns were attached to a casted tertiary structure to ensure adequate stability. A universal testing machine was used to determine the retentive force values at baseline and after 1, 3, 5, and 10 years of simulated aging in the presence of artificial saliva. Data were analyzed applying Kolmogorov-Smirnov, Kruskal-Wallis, and Mann-Whitney U test. Level of significance was set at p < 0.05. RESULTS: Retentive forces were not different for the groups ZE and ZP at baseline (median ZE 2.85 N; ZP 2.8 N; p <= 0.218). Because retentive force values changed significantly over simulation time for group ZE (Kruskal-Wallis; p <= 0.028), the values between the test groups ZE and ZP differed significantly (Mann Whitney U) at 5 years (ZE 3.03 N; ZP 2.76 N; p <= 0.003) and 10 years (ZE 3.1 N; ZP 2.78 N; p <= 0.011). CONCLUSIONS: PEEK secondary crowns exhibit stable retentive force values over 10 years of simulated aging showing no signs of deterioration while the retentive force values of electroformed secondary crowns increase over time. CLINICAL RELEVANCE: PEEK might be a suitable alternative to proven metallic materials for the fabrication of secondary crowns. PMID- 30293187 TI - Micron-scale crack propagation in laser-irradiated enamel and dentine studied with nano-CT. AB - OBJECTIVES: The aim of this study was to see the effect of Er:YAG laser irradiation in dentine and compare this with its effect in enamel. The mechanism of crack propagation in dentine was emphasised and its clinical implications were discussed. MATERIALS AND METHODS: Coronal sections of sound enamel and dentine were machined to 50-MUm thickness using a FEI-Helios Plasma (FIB). The specimen was irradiated for 30 s with 2.94-MUm Er:YAG laser radiation in a moist environment, using a sapphire dental probe tip, with the tip positioned 2 mm away from the sample surface. One of the sections was analysed as a control and not irradiated. Samples were analysed using the Zeiss Xradia 810 Ultra, which allows high spatial resolution, nanoscale 3D imaging using X-ray computed tomography (CT). RESULTS: Dentine: In the peritubular dentine, micro-cracks ran parallel to the tubules whereas in the inter-tubular region, the cracks ran orthogonal to the dentinal tubules. These cracks extended to a mean depth of approximately 10 MUm below the surface. On the dentine surface, there was preferential ablation of the less mineralised intertubular dentine, and this resulted in an irregular topography associated with tubules. Enamel: The irradiated enamel surface showed a characteristic 'rough' morphology suggesting some preferential ablation along certain microstructure directions. There appears to be very little subsurface damage, with the prismatic structure remaining intact. CONCLUSIONS: A possible mechanism is that laser radiation is transmitted down the dentinal tubules causing micro-cracks to form in the dentinal tubule walls that tend to be limited to this region. CLINICAL RELEVANCE: Crack might be a source of fracture as it represents a weak point and subsequently might lead to a failure in restorative dentistry. PMID- 30293188 TI - Impact of endodontic post material on longitudinal changes in interproximal bone level: a randomized controlled pilot trial. AB - OBJECTIVES: Aim was to evaluate the impact of glass fiber versus titanium endodontic posts on the interproximal bone level around severely damaged endodontically treated teeth. MATERIALS AND METHODS: Thirty-eight participants of a randomized controlled trial on glass fiber (n = 18) and titanium post endodontic restorations (n = 20) received radiographs at two different times after post placement (T0 = <12 months and T1 = 36-72 months after post placement). A total of 76 radiographs were analyzed with an image-editing software. Medians of changes in mesial and distal interproximal bone level (?MBL, ?DBL) were calculated and tested for statistical significance with respect to post material using Mann-Whitney U test (p < 0.05). Impact of post material on bone level changes was assessed in multilevel mixed-effect linear regression models. RESULTS: The mean observation period was 54 months for glass fiber and 50 months for titanium posts. Interproximal bone loss was small in both groups during the study period with no significant differences between groups (glass fiber group, ?MBL = - 0.03 mm and ?DBL = - 0.06 mm; titanium group, ?MBL = - 0.07 mm and ?DBL = - 0.17 mm; both p > 0.05). Overall, impact of post material on bone loss was almost negligible with a nonsignificant difference between materials of 0.10 mm during the entire study period. CONCLUSION: The rigidity of endodontic post material has no impact on the level of alveolar bone support of severely damaged endodontically treated teeth. CLINICAL RELEVANCE: Post-endodontic restorations of severely damaged teeth can achieve steady levels of periodontal bone support as a parameter of periodontal health, irrespective of post material. PMID- 30293186 TI - Effect of EDTA root conditioning on the outcome of coronally advanced flap with connective tissue graft: a systematic review and meta-analysis. AB - OBJECTIVES: CAF in combination with a connective tissue graft (CTG) is considered the technique of choice for treating gingival recessions (GRs). Among the many recognized factors that can affect the outcomes, the use of chemical agents has been proposed. The effect of EDTA, as a commonly used agent, remains controversial. Therefore, the aim of this review was to assess the efficacy of EDTA root conditioning when combined to CAF + CTG. MATERIAL AND METHODS: A literature search was conducted to identify randomized clinical trials (RCTs) that performed CAF + CTG with and without EDTA for root coverage procedures. The following outcomes were assessed: recession reduction (Rec Red), complete root coverage (CRC), keratinized tissue gain (KT gain), clinical attachment level changes (CAL gain), and changes in pocket depth (PD changes). RESULTS: Fourteen RCTs (575 GRs) were included and analyzed. Six articles were included in the EDTA group, with 8 in the non-EDTA group. Meta-analyses revealed statistically significant differences for the outcomes of Rec Red (3.68 mm versus 3.07 mm), CAL gain (4.15 mm versus 3.07 mm), and PD changes (- 0.44 mm versus 0.27 mm) in favor of the EDTA group, while outcomes of CRC (odds ratio of 1.15) and KT gain (1.98 mm versus 1.62 mm) were not significantly different. CONCLUSIONS: Limited evidence is available when evaluating the effectiveness of EDTA root conditioning with CAF + CTG. However, the adjunct application of EDTA with CAF + CTG appears to be beneficial. CLINICAL RELEVANCE: The adjunct application of EDTA may provide benefits when performing root coverage procedure via CAF + CTG. PMID- 30293189 TI - Screening of HNF1A and HNF4A mutation and clinical phenotype analysis in a large cohort of Chinese patients with maturity-onset diabetes of the young. AB - AIMS: The study aimed to screen the HNF1A and HNF4A mutation in a large Chinese cohort of high clinical suspicion of maturity-onset diabetes of the young (MODY) patients and characterize the clinical features of those patients. The performance of hsCRP as a biomarker to differentiate MODY3 from early onset T2DM was also evaluated. METHODS: A total of 74 patients with a strong clinical suspicion of MODY from 59 families and 33 newly diagnosed early-onset T2DM were included. HNF1A and HNF4A mutations were analyzed by Sanger sequencing. ROC curves were used to identify the optimal cutoff of hsCRP. RESULTS: One novel (c.864_865insG) and six recurrent HNF1A mutations (R203H, R263H, P379T, L422P, P519L and c.873delC) in 17 patients from 8 families (13.6%), as well as one novel HNF4A (R331H) mutation were identified. Nonspecific clinical presentations were observed in MODYX compared to MODY3 patients. MODY3 subjects exhibited with younger, lower BMI, TG, fasting and postprandial C-peptide, higher HDL than T2DM. Particularly, we confirmed serum hsCRP was lower in MODY3 than T2DM. ROC curve showed a good discrimination with an AUC of 0.852 and identified a cutoff hsCRP of 0.79 (75% sensitivity and 83% specificity). Good glycemic control was observed in all identified patients after switching to glimepiride therapy. CONCLUSIONS: The prevalence of HNF1A mutation was relatively lower in Mainland China and HNF4A mutation was rare. Serum hsCRP concentrations performed well in discriminating MODY3 from T2DM. Molecular diagnosis of MODY3/1 did transform management in clinical practice and facilitated the glycemic control. PMID- 30293190 TI - Periampullary Diverticula and ERCP Outcomes: A Systematic Review and Meta Analysis. AB - INTRODUCTION: Periampullary diverticulum (PAD) is most often asymptomatically found in elderly population. ERCP in the presence of PAD is technically challenging since the location and orientation of the ampulla could be altered. Various studies have reported differing results on the technical success and safety outcomes of ERCP in the presence of PAD. We aimed at a meta-analysis of such studies to assess the technical success and the occurrence of complications during ERCP in patients with PAD. METHODS: We conducted a comprehensive search of several databases and conference proceedings including PubMed, EMBASE, and Web of Science databases (earliest inception to October 2017). The search was done in accordance with PRISMA guidelines to identify studies. Studies that reported on the ERCP outcomes based on the presence of PAD were included. Both prospective and retrospective studies, manuscripts and abstracts were included. Only articles in English literature were included. The primary analysis focused on the overall technical success of ERCP in the presence of PAD, and the secondary analysis was to estimate the risk of occurrence of complications. RESULTS: Our search resulted in 16 studies that were included for final analysis. These 16 studies reported on 2794 patients, who had PAD, and the control group included 13,032 patients, who did not have a PAD during ERCP. Our meta-analysis of this data showed an Odd's ratio estimate of having a successful ERCP procedure in patients with PAD to be 0.51 [95% C.I. (0.35-0.72)] when compared to patients without it. This was statistically significant, with a p value 0.00. Considerable heterogeneity was noted among the studies. The heterogeneity proportion was quantified at 74.6% based on I2 statistic. The secondary outcomes measured were complications. We analyzed the pooled Post-ERCP Pancreatitis (PEP), cholangitis, perforation, and bleeding. Only those studies that had the data for these complications in both the study and the control groups were selected. PEP: The pooled Odd's estimate of having PEP was 1.28, [95% C.I (0.88-1.87)] from 12 studies reporting on 1863 patients with PAD in comparison with 7803 patients without it. The risk of PEP occurrence tended to be more in the group without PAD, though it was not statistically significant, with a p value 0.20. There was some heterogeneity observed between the studies, with the quantification I2 statistic being 28.6%. Our analysis shows that having PAD does not put a patient at increased risk for PEP. Bleeding: The pooled Odds estimate was 1.69, 95% C.I. 0.88-3.25 from nine studies reporting on 1816 patients with PAD in comparison with 5327 patients without it. This was not statistically significant, p value 0.11. Considerable heterogeneity was noted, with I2 being 55.7%. The risk of having a bleed was noted to be more in control group, and having PAD did not put patients at increased risk for bleeding during an ERCP procedure. Perforation: Patients with PAD undergoing ERCP were not at increased risk for perforation. Seven studies reported on this complication. This was noted in seven patients out of 1245 in study group, and 19 patients out of 4912 in control group. The pooled Odd's estimate was 1.24, 95% C.I. 0.54-2.87. There was no statistical significance, p value 0.61. No heterogeneity was noted among the studies included in this analysis. Cholangitis: Only four studies reported on this complication. In a total of 778 patients in study group, four had cholangitis and eight had this complication out of 3886 patients in the control group. The pooled Odd's was 2.12, 95% C.I. 0.61-7.33. There was no statistical significance, p value 0.24. No heterogeneity was noted. CONCLUSION: ERCP is technically feasible and increasingly successful when performed by experts in the presence of PAD. The risk of complications such as PEP, bleeding, perforation and cholangitis does not differ between ERCP done in patients with and without PAD. PMID- 30293192 TI - Biological studies of synthesized silver nanoparticles using Prosopis farcta. AB - The evaluation of cytotoxic and apoptotic activities of silver nanoparticles (Ag NPs) synthesized by aqueous extract of Prosopis farcta was investigated against lung (A549) and colon (HT-29) cell lines. The cytotoxic activity of nanoparticles was performed using MTT assay, while their apoptotic activity was tested using TUNEL method. The obtained results of MTT showed that the cell viability of A549 was dependent on the nanoparticles concentration and incubation time. Therefore, although the cytotoxic effect increased as the Ag-NPs concentration and incubation time heightened, yet the viability of HT-29 cells seems to be dependent only on the incubation time. The apoptotic results of the nanoparticles showed more than 50% of apoptosis on A549 and HT-29 cell lines, which in this case, HT-29 demonstrated 100% apoptosis at concentrations of more than 400 ug/ml. It seems that Ag-NPs synthesized using P. farcta extract can serve as anti-cancer agent in the treatment many cancers through creating or discovering new drug forms. PMID- 30293191 TI - Pancreas Pathology During the Natural History of Type 1 Diabetes. AB - PURPOSE OF REVIEW: We provide an overview of pancreas pathology in type 1 diabetes (T1D) in the context of its clinical stages. RECENT FINDINGS: Recent studies of pancreata from organ donors with T1D and non-diabetic donors expressing T1D-associated autoantibodies reveal pathological changes/disease mechanisms beyond the well-known loss of beta cells and lymphocytic infiltrates of the islets (insulitis), including beta-cell stress, dysfunction, and viral infections. Pancreas pathology evolves through disease stages, is asynchronous, and demonstrates a chronic disease that remains active years after diagnosis. Critically, beta-cell loss is not complete at onset, although young age is associated with increased severity. The recognition of multiple pathogenic alterations and the chronic nature of disease mechanisms during and after the development of T1D inform improved clinical trial design and reveal additional targets for therapeutic manipulation, in the context of an expanded time window for intervention. PMID- 30293193 TI - Successful radiofrequency catheter ablation of atrial fibrillation is associated with improvement in left ventricular energy loss and mechanics abnormalities. AB - Dissipative energy loss (EL), an index of inefficient blood flow, has not been studied in patients with atrial fibrillation (AF). We therefore assessed the effect of AF and of successful catheter ablation on left ventricular (LV) EL and global longitudinal strain (GLS) to explore the effect of inefficient blood flow on LV remodeling. In 53 patients undergoing catheter ablation for AF (AF group), LV EL (in mW/m) was evaluated by vector flow mapping (VFM) during systole (ELsys), early diastole (ELed) and atrial contraction phase (ELac), and GLS was calculated by two-dimensional tissue tracking (2DTT). Of the 53 patients, 37 patients who sustained sinus rhythm and completed echocardiographic evaluation at baseline and at 3 and 6 months follow-up were examined for change in EL and GLS. The latter parameters also were assessed in 44 age- and sex-matched controls. At baseline in AF group, ELsys and ELed were significantly higher (3.97 +/- 2.29 vs. 3.14 +/- 1.01; and 9.22 +/- 5.01 vs. 3.89 +/- 1.51; both P < 0.05, respectively), and GLS was lower (- 16.66 +/- 3.50 vs. - 19.95 +/- 2.40, P < 0.05) than in controls. During follow-up after catheter ablation, ELsys and ELed significantly improved at 3 months, and almost normalized at 6 months (both P < 0.05); GLS also improved significantly (P < 0.05). In multivariate logistic regression analysis, ELed was the only independent predictor for maintenance of sinus rhythm at 1-year follow-up (hazard ratio, 1.254; 95% confidence interval 1.073-1.467). VFM and 2DTT revealed impaired LV EL and GLS in patients with AF. Successful catheter ablation appeared to ameliorate impairment in intraventricular flow and mechanics. PMID- 30293195 TI - Bioprocesses for 2-phenylethanol and 2-phenylethyl acetate production: current state and perspectives. AB - 2-Phenylethanol (2-PE) and 2-phenethyl acetate (2-PEA) are valuable generally recognized as safe flavoring agents widely used in industry. Perfumes, pharmaceuticals, polishes, and personal care products, are some of the final products using these compounds as additives due to their rose-like odor. Also, 2 PE is used in disinfectants, pest control, and cleaning products due to its biocide capability. Although most of these additives production are derived from chemical synthesis, the current trend of consumers to prefer natural products has contributed to the development of biotechnological approaches as an alternative way to obtain natural 2-PE and 2-PEA. The most efficient route to bioproduce these compounds is through the bioconversion of L-phenylalanine via the Ehrlich pathway, and most of the advances have been focused on the development of this process. This review compiles the most recent developments in the biotechnological production of 2-PE and 2-PEA, indicating the most studied strains producing 2-PE and 2-PEA, the current advances in the in situ product recovery in liquid systems, an overview of the strain developments, and the progress in the use of residue-based systems. Future research should address the need for more sustainable and economic systems such as those using wastes as raw materials, as well as the scale-up of the proposed technologies. PMID- 30293196 TI - Biotransformation of industrial tannins by filamentous fungi. AB - Tannins are secondary metabolites that are widely distributed in the plant kingdom. They act as growth inhibitors for many microorganisms: they are released upon microbial attack, helping to fight infection in plant tissues. Extraction of tannins from plants is an active industrial sector with several applications, including oenology, animal feeding, mining, the chemical industry, and, in particular, the tanning industry. However, tannins are also considered very recalcitrant pollutants in wastewater of diverse origin. The ability to grow on plant substrates rich in tannins and on industrial tannin preparations is usually considered typical of some species of fungi. These organisms are able to tolerate the toxicity of tannins thanks to the production of enzymes that transform or degrade these substrates, mainly through hydrolysis and oxidation. Filamentous fungi capable of degrading tannins could have a strong environmental impact as bioremediation agents, in particular in the treatment of tanning wastewaters. PMID- 30293197 TI - PET imaging of noradrenaline transporters in Parkinson's disease: focus on scan time. AB - OBJECTIVE: In subjects with idiopathic Parkinson's disease (PD) the functional state of the locus coeruleus and the subtle derangements in the finely tuned dopamine-noradrenaline interplay are largely unknown. The PET ligand (S,S)-[11C] O-methylreboxetine (C-11 MRB) has been described to reliably bind noradrenaline transporters but long scanning protocols might hamper its use, especially in patients with PD. We aimed to assess the feasibility of reducing C-11 MRB scans to 30 min. METHODS: Ten patients with idiopathic PD underwent dynamic C-11 MRB PET (120 min duration) and brain magnetic resonance imaging. Model-based (i.e., simplified and multilinear reference tissue model 2) non-displaceable binding potentials (BP) of selected brain regions were analyzed for a 90 min scan protocol and compared with BP derived from static 30-min data with different starting times (30, 40, 50 and 60 min) after C-11 MRB injection. Intraclass correlation coefficient and linear regression analysis were used to explore the association between BP of different scan durations. Spearman's rho served to describe the correlation of BP with demographic and clinical parameters. RESULTS: With respect to kinetic models, BP50-80 and BP60-90 showed the best correlation in several brain areas (R2 range 0.95-98; p < 0.001). The thalamus showed the highest BP on average. No correlation between BP, clinical and demographic characteristics was observed. CONCLUSIONS: An acquisition time of 30 min, starting 50 or 60 min after C-11 MRB injection, allows a reliable estimation of noradrenaline transporter binding values in Parkinsonian people. A short acquisition time can significantly reduce the discomfort of Parkinsonian patients and facilitate PET studies, especially in the medication-off-state.

AB - Vitamin D supplementation is often used in the prevention and treatment of osteoporosis, but the role of vitamin D has lately been questioned. We aimed to investigate the effect of 3 months of daily vitamin D3 supplementation (70 ug [2800 IU] vs. placebo) initiated in winter months on bone health. This study is a double-blinded placebo-controlled randomized trial. Bone health was assessed by bone turnover markers, DXA, HRpQCT, and QCT scans. The participants were 81 healthy postmenopausal women with low 25(OH)D (< 50 nmol/l) and high PTH levels (> 6.9 pmol/l) at screening. Vitamin D3 supplementation significantly increased levels of 25(OH)D and 1,25(OH)2D by 59 nmol/l and 19 pmol/l, respectively, whereas PTH was reduced by 0.7 pmol/l (all p < 0.0001). Compared with placebo, vitamin D3 did not affect bone turnover markers, aBMD by DXA or trabecular bone score. Vitamin D3 increased trabecular vBMD (QCT scans) in the trochanter region (0.4 vs. - 0.7 g/cm3) and the femoral neck (2.1 vs. - 1.8 g/cm3) pall < 0.05. HRpQCT scans of the distal tibia showed reduced trabecular number (- 0.03 vs. 0.05 mm-1) and increased trabecular thickness (0.001 vs. - 0.005 mm), as well as an improved estimated bone strength as assessed by failure load (0.1 vs. - 0.1 kN), and stiffness (2.3 vs. - 3.1 kN/mm pall <= 0.01). Changes in 25(OH)D correlated significantly with changes in trabecular thickness, stiffness, and failure load. Three months of vitamin D3 supplementation improved bone strength and trabecular thickness in tibia, vBMD in the trochanter and femoral neck, but did not affect aBMD.

AB - We examined the association between posttraumatic stress disorder (+PTSD) symptoms and incident premenstrual syndrome (PMS) in a longitudinal study with 14 years follow-up of 2924 women aged 27-44. Compared to women with no trauma exposure, women with trauma/PTSD were at significantly increased risk of PMS (p trend < .001): 1) trauma/no PTSD odds ratio (OR) = 1.31 [95% confidence interval (CI) 1.05-1.63], 2) 1-3 PTSD symptoms OR = 1.71 [95% CI = 1.33-2.20], 3) 4-5 PTSD symptoms OR = 2.90 [95% CI = 2.07-4.05], and 4) 6-7 PTSD symptoms OR = 3.42 [95% CI = 2.18-5.36]. PMID- 30293200 TI - Irritant Contact Dermatitis. AB - Contact dermatitis accounts for 95% of occupational skin disorders. Irritant contact dermatitis (ICD) is often caused by cumulative exposure to weak irritants, accounting for 80% of all cases of contact dermatitis. ICD can co exist with atopic dermatitis (AD) and allergic contact dermatitis (ACD). Patients with AD and ACD may have a lower inflammatory threshold for developing ICD. Therefore, it needs to be distinguished from lesions of AD and ACD. ICD Patients report stinging and burning in excess of pruritus. Pruritus is classically reported by patients with AD and ACD. ICD lesions are typically well-demarcated unlike AD and ACD. ICD is diagnosed by exclusion. Patients undergo testing to rule out type I and type IV hypersensitivity. Negative results suggest a diagnosis of ICD. Management consists of irritant identification and avoidance with regular emollient use. Although ICD is more common in certain occupations, genetics and environment play significant roles in its development. PMID- 30293201 TI - Characterization of Maf1 in Arabidopsis: function under stress conditions and regulation by the TOR signaling pathway. AB - MAIN CONCLUSION: Maf1 repressor activity is critical for plant survival during environmental stresses, and is regulated by its phosphorylation/dephosphorylation through the activity of TOR and PP4/PP2A phosphatases. Maf1 is a global repressor of RNA polymerase III (Pol III), and is conserved in eukaryotes. Pol III synthesizes small RNAs, 5S rRNA, and tRNAs that are essential for protein translation and cell growth. Maf1 is a phosphoprotein and dephosphorylation of Maf1 promotes its repressor activity in yeast and mammals. Plant Maf1 was identified in citrus plants as a canker elicitor-binding protein, and citrus Maf1 represses cell growth associated with canker development. However, functions of plant Maf1 under diverse stress conditions and its regulation by the target of rapamycin (TOR) signaling components are poorly understood. In this study, the Arabidopsis maf1 mutants were more susceptible to diverse stresses and treatment with the TOR inhibitor Torin-1 than wild-type plants. The maf1 mutants expressed higher levels of Maf1 target RNAs, including 5S rRNA and pre-tRNAs in leaf cells, supporting Pol III repressor activity of Arabidopsis Maf1. Cellular stresses and Torin-1 treatment induced dephosphorylation of Maf1, suggesting Maf1 activation under diverse stress conditions. TOR silencing also stimulated Maf1 dephosphorylation, while silencing of catalytic subunit genes of PP4 and PP2A repressed it. Thus, TOR kinase and PP4/PP2A phosphatases appeared to oppositely modulate the Maf1 phosphorylation status. TOR silencing decreased the abundance of the target RNAs, while silencing of the PP4 and PP2A subunit genes increased it, supporting the positive correlation between Maf1 dephosphorylation and its repressor activity. Taken together, these results suggest that repressor activity of Maf1, regulated by the TOR signaling pathway, is critical for plant cell survival during environmental stresses. PMID- 30293202 TI - Evolutionary and functional analyses of the 2-oxoglutarate-dependent dioxygenase genes involved in the flavonoid biosynthesis pathway in tobacco. AB - MAIN CONCLUSION: This study illustrates the differences in the gene structure of 2-oxoglutarate-dependent oxygenase involved in flavonoid biosynthesis (2ODD-IFB), and their potential roles in regulating tobacco flavonoid biosynthesis and plant growth. Flavonol synthase (FLS), anthocyanidin synthase (ANS), and flavanone 3beta-hydroxylase belong to the 2-oxoglutarate-dependent (2ODD) oxygenase family, and each performs crucial functions in the biosynthesis of flavonoids. We identified two NtFLS genes, two NtANS genes, and four NtF3H genes from Nicotiana tabacum genome, as well as their homologous genes in the N. sylvestris and N. tomentosiformis genomes. Our phylogenetic analysis indicated that these three types of genes split from each other before the divergence of gymnosperms and angiosperms. FLS evolved faster in the eudicot plants, whereas ANS evolved faster in the monocot plants. Gene structure analysis revealed two fragment insertions occurred at different times in the intron one position of tobacco FLS genes. Homologous protein modeling revealed distinct structures in the N terminus of the tobacco 2ODD oxygenases. We found that the expression patterns of genes encoding tobacco 2ODD oxygenases in flavonoids biosynthesis (2ODD-IFB) did not determine the accumulation patterns of flavonoids among various tobacco tissues, but strongly affected the concentration of flavonoids in the tissues, where they were biosynthesized. More carbon resource flowed to the flavonol biosynthesis when NtANS gene was silenced, otherwise more anthocyanidin accumulated when NtFLS gene was repressed. This study illustrates the 2ODD-IFB gene structure evolution, differences among their protein structures, and provides a foundation for regulating plant development and altering flavonoid content and/or composition through the manipulation of plant 2ODD-IFB genes.

PMID- 30293203 TI - The application of finite element modelling based on clinical pQCT for classification of fracture status. AB - Fracture risk assessment using dual-energy X-ray absorptiometry (DXA) frequently fails to diagnose osteoporosis amongst individuals who later experience fragility fractures. Hence, more reliable techniques that improve the prediction of fracture risk are needed. In this study, we evaluated a finite element (FE) modelling framework based on clinical peripheral quantitative computed tomography (pQCT) imaging of the tibial epiphysis and diaphysis to predict the stiffness at these locations in compression, shear, torsion and bending. The ability of these properties to identify a group of women who had recently sustained a low-trauma fracture from an age- and weight-matched control group was determined and compared to clinical pQCT and DXA properties and structural properties based on composite beam theory. The predicted stiffnesses derived from the FE models and composite beam theory were significantly different (p < 0.05) between the control and fracture groups, whereas no meaningful differences were observed using DXA and for the stress-strain indices (SSIs) derived using pQCT. The diagnostic performance of each property was assessed by the odds ratio (OR) and the area under the receiver operating curve (AUC), and both were greatest for the FE predicted shear stiffness (OR 16.09, 95% CI 2.52-102.56, p = 0.003) (AUC: 0.80, 95% CI 0.67-0.93). The clinical pQCT variable total density (rhotot) and a number of structural and FE-predicted variables had a similar probability of correct classification between the control and fracture groups (i.e. ORs and AUCs with mean values greater than 5.00 and 0.80, respectively). In general, the diagnostic characteristics were lower for variables derived using DXA and for the SSIs (i.e. ORs and AUCs with mean values of 1.65-2.98 and 0.64-0.71, respectively). For all properties considered, the trabecular-dominant tibial epiphysis exhibited enhanced classification characteristics, as compared to the cortical-dominant tibial diaphysis. The results of this study demonstrate that bone properties may be derived using FE modelling that have the potential to enhance fracture risk assessment using conventional pQCT or DXA instruments in clinical settings. PMID- 30293205 TI - Multimodal imaging of multifocal chorioretinitis secondary to endogenous candida infection. AB - PURPOSE: To present multimodal imaging of multifocal chorioretinitis secondary to endogenous candida infection in a young adult. METHODS: A 49-year-old woman who presented for evaluation of bilateral endogenous candida chorioretinitis underwent complete ophthalmic examination, in addition to fundus photography (FP), enhanced depth imaging optical coherence tomography, fundus autofluorescence (FAF), fluorescein angiography (FA), indocyanine green angiography (ICGA) and optical coherence tomography angiography (OCTA). RESULTS: Multimodal imaging of both eyes of the patient affected by endogenous candida chorioretinitis was performed. FP showed multiple white chorioretinal lesions at the posterior pole, FAF showed dark dot at the posterior pole surrounded by hyperautofluorescence area, FA showed early hyperfluorescence round perifoveal lesion at the posterior pole and small hyperfluorescence dots under the inferior retinal vessels. Early ICGA showed hypofluorescence dots at the posterior pole. Late ICGA showed dark hypofluorescence dots at the posterior pole surrounded by faint hyperautofluorescent ring. OCTA showed dark areas corresponded to hypoperfusion areas seen with early ICGA. CONCLUSION: We reported multimodal imaging of an unusual occurrence of multifocal chorioretinitis due to immunosuppression. These findings suggested that the infection resulted from choroidal infiltration via the short posterior ciliary arteries with resultant breakthrough into the retina, rather than via the central retinal artery. By comparing findings on OCTA with data obtained from traditional systems, we are gaining essential information on the pathogenesis of endogenous candida chorioretinitis. PMID- 30293194 TI - Safety of the fungal workhorses of industrial biotechnology: update on the mycotoxin and secondary metabolite potential of Aspergillus niger, Aspergillus oryzae, and Trichoderma reesei. AB - This review presents an update on the current knowledge of the secondary metabolite potential of the major fungal species used in industrial biotechnology, i.e., Aspergillus niger, Aspergillus oryzae, and Trichoderma reesei. These species have a long history of safe use for enzyme production. Like most microorganisms that exist in a challenging environment in nature, these fungi can produce a large variety and number of secondary metabolites. Many of these compounds present several properties that make them attractive for different industrial and medical applications. A description of all known secondary metabolites produced by these species is presented here. Mycotoxins are a very limited group of secondary metabolites that can be produced by fungi and that pose health hazards in humans and other vertebrates when ingested in small amounts. Some mycotoxins are species-specific. Here, we present scientific basis for (1) the definition of mycotoxins including an update on their toxicity and (2) the clarity on misclassification of species and their mycotoxin potential reported in literature, e.g., A. oryzae has been wrongly reported as an aflatoxin producer, due to misclassification of Aspergillus flavus strains. It is therefore of paramount importance to accurately describe the mycotoxins that can potentially be produced by a fungal species that is to be used as a production organism and to ensure that production strains are not capable of producing mycotoxins during enzyme production. This review is intended as a reference paper for authorities, companies, and researchers dealing with secondary metabolite assessment, risk evaluation for food or feed enzyme production, or considerations on the use of these species as production hosts. PMID- 30293206 TI - Aggressiveness of Localized Prostate Cancer: the Key Value of Testosterone Deficiency Evaluated by Both Total and Bioavailable Testosterone: AndroCan Study Results. AB - Failure rates after first-line treatment of localized prostate cancer (PCa) treatment remain high. Improvements to patient selection and identification of at risk patients are central to reducing mortality. We aimed to determine if cancer aggressiveness correlates with androgen levels in patients undergoing radical prostatectomy for localized PCa. We performed a prospective, multicenter cohort study between June 2013 and June 2016, involving men with localized PCa scheduled to undergo radical prostatectomy. Clinical and hormonal patient data (testosterone deficiency, defined by total testosterone (TT) levels < 300 ng/dL and/or bioavailable testosterone (BT) levels < 80 ng/dL) were prospectively collected, along with pathological assessment of preoperative biopsy and subsequent radical prostatectomy specimens, using predominant Gleason pattern (prdGP) 3/4 grading. Of 1343 patients analyzed, 912 (68%) had prdGP3 PCa and 431 (32%) had high-grade (prdGP4, i.e., ISUP >= 3) disease on prostatectomy specimens. Only moderate concordance in prdGP scores between prostate biopsies and prostatectomy specimens was found. Compared with patients with prdGP3 tumors (i.e., ISUP <= 2), significantly more patients with prdGP4 cancers had demonstrable hypogonadism, characterized either by BT levels (17.4% vs. 10.7%, p < 0.001) or TT levels (14.2% vs. 9.7%, p = 0.020). BT levels were also lower in patients with prdGP4 tumors compared to those with prdGP3 disease. Testosterone deficiency (defined by TT and/or BT levels) was independently associated with higher PCa aggressiveness. BT is a predictive factor for prdGP4 disease, and evaluating both TT and BT to define hypogonadism is valuable in preoperative assessment of PCa (AndroCan Trial: NCT02235142). PMID- 30293207 TI - Nivolumab for Treating Metastatic or Unresectable Urothelial Cancer: An Evidence Review Group Perspective of a NICE Single Technology Appraisal. AB - As part of its single technology appraisal (STA) process, the National Institute for Health and Care Excellence (NICE) invited the manufacturer (Bristol-Myers Squibb) of nivolumab (Opdivo(r)) to submit evidence of its clinical and cost effectiveness for metastatic or unresectable urothelial cancer. Kleijnen Systematic Reviews Ltd, in collaboration with Maastricht University Medical Centre+, was commissioned to act as the independent Evidence Review Group (ERG), which produced a detailed review of the evidence for the clinical and cost effectiveness of the technology, based on the company's submission to NICE. Nivolumab was compared with docetaxel, paclitaxel, best supportive care and retreatment with platinum-based chemotherapy (cisplatin plus gemcitabine, but only for patients whose disease has had an adequate response in first-line treatment). Two ongoing, phase I/II, single-arm studies for nivolumab were identified, but no studies directly compared nivolumab with any specified comparator. Evidence from directly examining the single arms of the trial data indicated little difference between the outcomes measured from the nivolumab and comparator studies. A simulated treatment comparison (STC) analysis was used in an attempt to reduce the bias induced by naive comparison, but there was no clear evidence that risk of bias was reduced. Multiple limitations in the STC were identified and remained. The effect of an analysis based on different combinations of covariates in the prediction model remains unknown. The ERG's concerns regarding the economic analysis included the use of a non-established response-based survival analysis method, which introduced additional uncertainty. The use of time-dependent hazard ratios produced overfitting and was not represented in the probabilistic sensitivity analysis. The use of a treatment stopping rule to cap treatment cost left treatment effectiveness unaltered. A relevant comparator was excluded from the base-case analysis. The revised ERG deterministic base-case incremental cost-effectiveness ratios based on the company's Appraisal Consultation Document response were L58,791, L78,869 and L62,352 per quality-adjusted life-year gained versus paclitaxel, docetaxel and best supportive care, respectively. Nivolumab was dominated by cisplatin plus gemcitabine in the ERG base case. Substantial uncertainties about the relative treatment effectiveness comparing nivolumab against all comparators remained. NICE did not recommend nivolumab, within its marketing authorisation, as an option for treating locally advanced, unresectable or metastatic urothelial carcinoma in adults who have had platinum-containing therapy, and considered that nivolumab was not suitable for use within the Cancer Drugs Fund. PMID- 30293208 TI - Effect of Synbiotic and Probiotic Supplementation on Serum Levels of Endothelial Cell Adhesion Molecules in Hemodialysis Patients: a Randomized Control Study. AB - : The aim of this study was to investigate the effect of synbiotic and probiotic supplementation on serum vascular dysfunction and necrosis markers in hemodialysis (HD) patients. In this randomized, double-blind, placebo-controlled trial, 75 HD patients were randomly assigned to either the synbiotic or probiotic or placebo group. The patients in the synbiotic group received 15 g of prebiotics and 5 g probiotic powder containing Lactobacillus acidophilus strain T16 (IBRC M10785), Bifidobacterium bifidum strain BIA-6, Bifidobacterium lactis strain BIA 6, Bifidobacterium longum strain LAF-5 (2.7 * 107 CFU/g each) in sachets (n = 25), whereas the probiotic group received 5 g probiotics same to the first group with 15 g of maltodextrin powder in sachets (n = 25) and the placebo group received 20 g of maltodextrin powder in sachets (n = 25) for 12 weeks. At baseline and the end of the study, serum concentrations of soluble intercellular adhesion molecule type 1 (sICAM-1), soluble vascular cell adhesion molecule type 1 (sVCAM-1), cytokeratin 18 (CK-18) as the necrosis marker, uric acid, and phosphate levels were measured. Feces also were collected for microbiota colony counting. Serum ICAM-1 level reduced significantly in the synbiotic group after the intervention period (P = 0.02), and this reduction was significantly different in the synbiotic group in comparison to the placebo group (P = 0.03). Serum levels of VCAM-1 and CK-18 were not significantly different between the groups. However, the reduction in serum levels of VCAM-1 in the synbiotic group was significantly higher in comparison to the placebo group (P = 0.01). Multivariate linear regression analysis revealed that ? phosphate was the sole independent determinant of ?ICAM-1 (P = 0 < 001). The study indicated that synbiotic supplementation reduced serum ICAM-1 level, which is a risk factor for cardiovascular diseases in HD patients, but has no effect on the necrosis marker.

PMID- 30293209 TI - Update on Vaccinating the Patient With Inflammatory Bowel Disease. AB - PURPOSE OF REVIEW: Patients with inflammatory bowel disease (IBD) are at increased risk of infectious diseases independent of their immunosuppression status, and yet, studies suggest that this population is not receiving standard vaccinations at the same rate as the general population. This review seeks to understand why IBD patients may not be receiving recommended immunizations and to provide guidelines on vaccinating this vulnerable population. RECENT FINDINGS: Inactive vaccines are recommended for patients with IBD regardless of immunosuppression status due to the increased risk for many vaccine-preventable illnesses. Certain live vaccines can be administered to the immunocompromised patient with IBD. Additionally, many patients with IBD will be immunosuppressed some time in their disease course, further increasing their risk for infection. Despite this understanding, patients with IBD have poor vaccination rates. Inadequate knowledge, limited time with patients, and lack of consensus as to who is responsible for identifying and administering vaccinations are some of the most important barriers to vaccinating the patient with IBD. In this review, we discuss guidelines for vaccinating both the immunocompetent and immunosuppressed patient with IBD as well as provide vaccine-specific recommendations. The evidence suggests that patients with IBD are not receiving recommended vaccinations because of misconceptions on the part of patients as well as a paucity of knowledge by their health care team. Educational programs can be successfully implemented to increase knowledge about appropriate vaccinations and can ultimately increase vaccine uptake among patients with IBD. In the end, gastroenterologists and primary care physicians must work together with their patients with IBD to ensure that recommended vaccinations are administered. PMID- 30293211 TI - BRCA mutations: is everything said? AB - BACKGROUND: Mutations in the BRCA1 and BRCA2 genes constitute a risk factor for breast cancer development. BRCA mutation research has been an active field since the discovery of the genes, and new mutations in both genes are constantly described and classified according to several systems. AIM: We intend to provide an overview of the current state of BRCA1 and BRCA2 mutation description and classification. We wanted to know whether there was a trend towards a more frequently described mutation type and what the proportion of pathogenic mutations was. RESULTS: We found that, although new mutations are described each year as reflected in current database records, very few of them are reported in papers. Classification systems are highly heterogeneous and a consensus among them is still under development. Regarding their function, a large number of mutations are yet to be analyzed, a very complex task, due to the great number of possible variations and their diverse effect in the BRCA gene functions. After individual analysis, many variants of unknown significance turn out to be pathogenic, and many can disrupt interactions with other proteins involved in mechanisms such as DNA damage repair pathways. Recent data suggest that looking for mutation patterns or combinations would shed a wider light on BRCA-derived cancer susceptibility in the upcoming years. PMID- 30293212 TI - Racial/ethnic differences in the outcomes of patients with metastatic breast cancer: contributions of demographic, socioeconomic, tumor and metastatic characteristics. AB - PURPOSE: Population-based estimates of racial disparities in metastatic breast cancer are lacking. We quantified the contributions of demographic, socioeconomic, tumor, and metastatic characteristics to racial differences in metastatic breast cancer and characterized the most disproportional subgroup. METHODS: Patients diagnosed with metastatic breast cancer between 2010 and 2014 were identified using the Surveillance, Epidemiology, and End Results database. A multivariable Cox proportional hazards model was used to adjust each set of variables. The excess relative risk of cancer-specific and all-cause death in non Hispanic black (NHB) versus non-Hispanic white women diagnosed with metastatic breast cancer was expressed as a percentage and was stratified by the age at diagnosis. RESULTS: We identified 13,066 female patients. NHB women exhibited substantially higher morbidity and mortality than women of other races/ethnicities. The greatest excess mortality risk for NHB women was observed in the young-onset group (18-49 years; hazard ratio: 1.57), followed by the middle-age group (50-64 years; hazard ratio: 1.42); the trend was not significant among the elderly group. Socioeconomic factors stably explained one-half of the excess risk, whereas the contribution of tumor characteristics obviously decreased with age (18-49 years, 40.7%; 50-64 years, 33.9%), and the metastatic pattern accounted for approximately one-tenth of the excess risk. Additionally, the disproportional death burden of NHB women persisted in less aggressive subgroups. CONCLUSIONS: By providing a comprehensive assessment of racial differences in the incidence and outcomes of patients with metastatic breast cancer, we urge the implementation of targeted preventive efforts in both the public health and clinical arenas. PMID- 30293214 TI - Ex vivo visualization of the trigeminal pathways in the human brainstem using 11.7T diffusion MRI combined with microscopy polarized light imaging. AB - Classic anatomical atlases depict a contralateral hemispheral representation of each side of the face. Recently, however, a bilateral projection of each hemiface was hypothesized, based on animal studies that showed the coexistence of an additional trigeminothalamic tract sprouting from the trigeminal principal sensory nucleus that ascends ipsilaterally. This study aims to provide an anatomical substrate for the hypothesized bilateral projection. Three post-mortem human brainstems were scanned for anatomical and diffusion magnetic resonance imaging at 11.7T. The trigeminal tracts were delineated in each brainstem using track density imaging (TDI) and tractography. To evaluate the reconstructed tracts, the same brainstems were sectioned for polarized light imaging (PLI). Anatomical 11.7T MRI shows a dispersion of the trigeminal tract (tt) into a ventral and dorsal portion. This bifurcation was also seen on the TDI maps, tractography results and PLI images of all three specimens. Referring to a similar anatomic feature in primate brains, the dorsal and ventral tracts were named the dorsal and ventral trigeminothalamic tract (dtt and vtt), respectively. This study shows that both the dtt and vtt are present in humans, indicating that each hemiface has a bilateral projection, although the functional relevance of these tracts cannot be determined by the present anatomical study. If both tracts convey noxious stimuli, this could open up new insights into and treatments for orofacial pain in patients. PMID- 30293215 TI - The association between urinary sodium excretion and blood pressure in a community-based population: the Yamagata (Takahata) study. AB - BACKGROUND: The association between salt intake and blood pressure levels is still inconclusive, and may be influenced by patient characteristics. We thus conducted a community-based cross-sectional study. METHODS: This study included 2297 subjects aged >= 40 years not on antihypertensive medication at the time of a health check-up. We examined the association between blood pressure levels and the estimated amount of 24-h urinary sodium excretion (e24hUNa) stratified by background characteristics. The 24-h urinary excretion levels of sodium and potassium were estimated from Kawasaki's equation using a spot urine sample. RESULTS: The association of systolic blood pressure (SBP) and diastolic blood pressure (DBP) with e24hUNa was significantly positive in a multiple linear regression model adjusted for confounders including age, sex, smoking, alcohol consumption, body mass index, diabetes, hypercholesterolemia, renal function, and potassium excretion. The regression coefficients of changes in SBP and DBP per 1 SD increase in e24hUNa (53 mEq/day) were + 1.91 mmHg and + 0.94 mmHg, respectively. In the subgroup analyses, the increase in SBP was especially greater in the elderly, in subjects with diabetes, and in subjects with reduced renal function compared to those in the counterparts. The association between SBP and e24hUNa was insignificant in subjects with eGFR >= 90 ml/min/1.73m2, while the association with progression of renal dysfunction was stronger and significant. CONCLUSIONS: These results demonstrated that the association between blood pressure and urinary sodium excretion was strengthened by characteristics of subjects such as aging, presence of diabetes, and renal impairment in the community-based population. PMID- 30293216 TI - Clinical significance of mesangial IgM deposition in patients with IgA nephropathy. AB - BACKGROUND: Glomerular immunoglobulin G deposition in patients with immunoglobulin A nephropathy (IgAN) has been shown to be associated with adverse renal outcomes. Clinical significance of mesangial immunoglobulin M (IgM) deposition in these patients remains to be proven. METHODS: One hundred patients who had a diagnosis of IgAN between 2001 and 2017 were enrolled. Patients were divided into two groups based on mesangial IgM deposition status. Groups were compared for demographic, clinical, and pathologic variables at baseline and in follow-up. Cox regression analysis was performed to evaluate the effect of mesangial IgM positivity on renal survival. RESULTS: IgM-positive group included 51% of participants. Baseline demographic and clinical parameters were not significantly different between groups. Mesangial IgM deposition was significantly associated with a higher segmental sclerosis score (p = 0.008). At last visit, median serum creatinine was higher (p = 0.021) and eGFR was lower (p = 0.006) in IgM-positive group. Nineteen (19%) of all patients reached the combined primary outcome which includes doubling in serum creatinine or evolution to ESRD. Cumulative renal survival was lower (p = 0.001) and resistant disease was more frequent in IgM-positive group (p = 0.026). Renal survival at 15 years was 94.2% and 59.7% in IgM-negative and IgM-positive groups, respectively (p = 0.006). Time-averaged proteinuria (HR 2.9; 95% CI 1.9-4.5; p < 0.001) and mesangial IgM deposition (HR, 13.2; 95% CI 1.9-93.1; p = 0.01) were found to be independent predictors of unfavorable renal outcomes. CONCLUSIONS: In conclusion, we demonstrated that mesangial IgM deposition independently associated with worse renal outcomes in patients with IgA nephropathy. PMID- 30293217 TI - Massive bone marrow necrosis revealing an HIV-related primary bone marrow lymphoma: a diagnostic challenge. AB - Bone marrow necrosis (BMN) is a condition that can be difficult to diagnose, requiring a hematologist experienced in bone marrow morphology. This diagnostic challenge should alert the clinician of a severe disease or a possible underlying malignancy, either hematological or a solid tumor. We describe the concomitant presence of a primary bone marrow lymphoma (diffuse large B-cell lymphoma-DLBCL), along with an extensive BMN in an HIV patient for the first time in a living individual. HIV infection, BMN and DLBCL presented a multifactorial crossword of molecular events underlying the complex pathophysiology. The exact precipitating pathophysiological events resulting in BMN remain obscure and provide their clear impact for future research. The present report is instructive and also contains a critical review of the literature related to the case presented. PMID- 30293213 TI - Multilayered heterogeneity as an intrinsic hallmark of neuroendocrine tumors. AB - Neuroendocrine tumors (NETs) comprise a complex and highly heterogeneous group of neoplasms that can arise all over the body, originating from neuroendocrine cells. NETs are characterized by a general lack of symptoms until they are in advanced phase, and early biomarkers are not as available and useful as required. Heterogeneity is an intrinsic, pivotal feature of NETs that derives from diverse causes and ultimately shapes tumor fate. The different layers that conform NET heterogeneity include a wide range of distinct characteristics, from the mere location of the tumor to its clinical and functional features, and from its cellular properties, to the core signaling and (epi)genetic components defining the molecular signature of the tumor. The importance of this heterogeneity resides in that it translates into a high variability among tumors and, hence, patients, which hinders a more precise diagnosis and prognosis and more efficacious treatment of these diseases. In this review, we highlight the significance of this heterogeneity as an intrinsic hallmark of NETs, its repercussion on clinical approaches and tumor management, and some of the possible factors associated to such heterogeneity, including epigenetic and genetic elements, post-transcriptional regulation, or splicing alterations. Notwithstanding, heterogeneity can also represent a valuable and actionable feature, towards improving medical approaches based on personalized medicine. We conclude that NETs can no longer be viewed as a single disease entity and that their diagnosis, prognosis and treatment must reflect and incorporate this heterogeneity. PMID- 30293218 TI - Real-world Comparative Effectiveness of Tocilizumab Monotherapy vs. Tumor Necrosis Factor Inhibitors with Methotrexate in Patients with Rheumatoid Arthritis. AB - INTRODUCTION: Controlled clinical studies have shown that the efficacy of tocilizumab (TCZ) monotherapy is superior to that of tumor necrosis factor inhibitor (TNFi) monotherapy and comparable to that of TCZ plus methotrexate (MTX) for the treatment of rheumatoid arthritis (RA). This study compared the real-world effectiveness of TCZ monotherapy vs. TNFis plus MTX in US patients with RA. METHODS: TCZ-naive patients from the Corrona RA registry with prior exposure to >= 1 TNFi who initiated TCZ monotherapy or TNFi + MTX were included. Outcomes included mean change in Clinical Disease Activity Index (CDAI), achievement of low disease activity (LDA; CDAI <= 10), achievement of modified American College of Rheumatology (mACR) 20/50 responses, and mean change in modified Health Assessment Questionnaire (mHAQ) at 6 months. Patients initiating TNFi + MTX were grouped by MTX dose (<= 10 mg; > 10 to <= 15 mg; > 15 to <= 20 mg; > 20 mg); outcomes in each group were compared with TCZ monotherapy using trimmed populations (excluding patients outside the propensity score distribution overlap). RESULTS: Patients in all groups experienced improvement in CDAI at 6 months (mean change, - 6.9 to - 9.7), with no significant differences between the TCZ monotherapy and TNFi + MTX groups. Achievement of LDA and mACR responses at 6 months were comparable between the TCZ monotherapy and TNFi + MTX groups; overall, 26.8-38.0% of patients achieved LDA, 24.3-37.6% achieved mACR20 response and 13.2-20.8% achieved mACR50 response. The mean change in mHAQ at 6 months was 0.1 in all groups. CONCLUSIONS: In this real-world population of US patients with RA who had prior TNFi exposure, there was no evidence of a difference in the effectiveness of TCZ monotherapy compared with that of TNFi + MTX, regardless of MTX dose, at 6 months for improving RA disease activity.

AB - Persistent left superior vena cava (PLSVC) is the most common anomalous thoracic venous drainage. A PLSVC usually drains into the right atrium through a dilated coronary sinus. It is rare that a PLSVC flows directly into the left atrium, and even rarer that it connects to the left upper pulmonary vein (LUPV). We report a case, wherein the LUPV connected to both the PLSVC and the left atrium. PMID- 30293221 TI - In order to ensure that evidence is unbiased it is sometimes necessary to retreat to the scientific ivory tower.

PMID- 30293222 TI - Melioidosis mimicking miliary tuberculosis. AB - Melioidosis is an infectious disease caused by Burkholderia pseudomallei, a gram negative intracellular bacillus. Tuberculosis, also an infectious disease, is caused by Mycobacterium tuberculosis, an acid fast bacillus. In both diseases, patients commonly present with fever and respiratory symptoms due to sepsis which might lead to respiratory failure or sudden death if left untreated. Not only are these two entities similar in clinical presentation, but the autopsy findings may mimic each other, giving rise to difficulties in determining the cause of death. We report a case of melioidosis and compare it to a typical case of miliary tuberculosis. Similarities between the cases on gross and histopathological examinations are discussed. In such circumstances, microbiological culture of bodily fluids and internal organs should be performed to ascertain the correct cause of death. PMID- 30293223 TI - Sodium nitrite food poisoning in one family. AB - Sodium nitrite is used as a coloring agent or preservative in food, as well as an antimicrobial agent in meat and fish and some cheeses. In high amounts it can be toxic for humans, causing methemoglobinemia. This is an unusual and potentially fatal condition in which hemoglobin is oxidized to methemoglobin (MHb), reducing the amount of oxygen that is released from hemoglobin, similar to carbon monoxide poisoning. MHb levels of 70% are generally lethal, but the existence of underlying anemia, acidosis, respiratory compromise, and cardiac disease may exacerbate the toxicity of MHb. We present a case of poisoning with sodium nitrite in three family members after eating homemade sausages given to them by their neighbor who was a butcher. According to the findings of the veterinary inspectorate in charge of food control in this case, the concentration of sodium nitrite in the homemade sausages was about 3.5 g per 1 kg of meat, almost 30 times higher than allowed according to legislation. In this case report, a 70 year-old man died about 7 h after consuming the meal, while two women, 53 and 67 years of age, respectively, were admitted to a toxicology clinic the following day due to food poisoning, with the maximum concentration of MHb in blood of 33.7 and 20.4%, respectively. They were discharged 3 days later. The autopsy of the deceased man showed sodium nitrite poisoning with a relatively low concentration of MHb in his blood - 9.87%. Death was attributed to the exacerbation of hypertensive and ischemic heart disease, resulting from accidental sodium nitrite poisoning. The presented cases illustrate the necessity of close cooperation between the authorities, medical staff, veterinary inspectorate, and forensic pathologists in determining the source of poisoning, the cause of death of the victim, and preventing the outbreak of poisoning among a greater number of consumers. PMID- 30293224 TI - Knowledge, attitude, and practice of healthcare professionals toward clinically applying graduated compression stockings: results of a Chinese web-based survey. AB - This study had three objectives: (1) to investigate healthcare professionals' knowledge, attitude, and practice toward clinically applying graduated compression stockings, (2) to analyze the influencing factors, and (3) to provide data to support departments that develop health policies. A self-administered web based survey was completed by 1,444 healthcare professionals, including physicians and nurses from 15tertiary hospitals and four secondary hospitals from 10 provinces in China. Reliability analysis and exploratory factor analysis were used to evaluate the researcher-designed questionnaire's reliability and validity. The formal questionnaire, which included demographic data (eight items), knowledge (ten items), attitudes (four items), and clinical practice patterns (six items), was distributed among healthcare professionals. The relationships and mechanisms among the variables were explored using descriptive statistical analysis, Pearson's correlation coefficients, and multiple linear regression analysis. Of the 1,444 respondents, 31.2% had good knowledge of clinically applying graduated compression stockings, 83.5% had a positive attitude toward clinically applying them, and 30.4% of respondents exhibited normative behavior when applying them. The multiple linear regression analysis indicated that training was an important factor influencing the knowledge, attitude, and practice toward clinically applying graduated compression stockings. The healthcare professionals' attitude toward clinically applying graduated compression stockings was positive, but the related knowledge was poor, and the code of behavior was deficient. Medical institutions should improve training for clinically applying graduated compression stockings among healthcare professionals and standardize the use of graduated compression stockings to facilitate the prevention of hospital-acquired venous thromboembolism. PMID- 30293225 TI - Intraocular pressure and wound state immediately after long versus short clear corneal incision cataract surgery. AB - PURPOSE: To compare the intraocular pressure (IOP) and wound state immediately after cataract surgery for eyes with a long clear corneal incision (CCI) with those for eyes with a short CCI. STUDY DESIGN: Randomized clinical trial. METHODS: One hundred twenty-eight eyes of 128 patients scheduled for phacoemulsification were randomly assigned to undergo long (>= 1.75 mm) or short (< 1.75 mm) CCI (2.4-mm wide). IOP was measured using a rebound tonometer preoperatively, at the conclusion of surgery, and at 30 min, 60 min, 120 min, 180 min, and 24 h postoperatively. Wound architecture determined using anterior segment-optical coherence tomography and flare intensity was examined at 60 min postoperatively. RESULTS: The mean incision length was significantly longer in the long CCI group (2.02 +/- 0.19 mm) than in the short CCI group (1.50 +/- 0.13mm; P < .0001). The mean IOP significantly increased at 120 min and 180 min postoperatively (P <= .0005) and returned to the preoperative level within 24 h. The mean IOP did not differ significantly between the long and short CCI groups at any follow-up period. The incidence of IOP lower than 10 mmHg did not differ significantly between the groups. The mean flare intensity was significantly greater in the short CCI group than in the long CCI group (P = .0122). The wound architecture was similar between the groups. CONCLUSION: IOP and wound architecture were comparable between eyes with a long CCI and eyes with a short CCI in the immediate postoperative periods up to 24 h, suggesting that wound stability is equivalent when the CCI is securely closed with wound hydration. PMID- 30293226 TI - Automated segmentation of en face choroidal images obtained by optical coherent tomography by machine learning. AB - PURPOSE: To develop an automated method to segment the choroidal layers of en face optical coherent tomography (OCT) images by machine learning. STUDY DESIGN: A cross-sectional, prospective study of 276 eyes of 181 healthy subjects. METHODS: OCT en face images of the choroid were obtained every 2.6 MUm from the retinal pigment epithelium (RPE) to the chorioscleral border. The images at the start of the choriocapillaris, start of Sattler's layer, and start of Haller's layer were identified, and the image numbers from the RPE line were taken as the teacher data. Forty-one feature quantities of each image were extracted. A support vector machine (SVM) model was created from each feature value of the training data, and a coefficient of determination was calculated for each layer of the choroid by a fivefold cross validation. Next, the same evaluation was performed after creating a SVM model with selected effective feature quantities. RESULTS: The mean coefficient of determination using all features was 0.9853 +/- 0.0012. Nine effective feature quantities (relative choroid thickness, mean/kurtosis/variance of brightness, FFT_ skewness, k0_vessel width, k1/k2/k4_vessel area) were selected, and the mean of the coefficient of determinations with these quantities In this model was 0.9865 +/- 0.0001. The number of errors in the image number at the start of each layer was 1.01 +/- 0.79 for the choriocapillaris, 1.13 +/- 1.12 for Sattler's layer, and 3.77 +/- 2.90 for Haller's layer. CONCLUSION: Automated stratification of the choroid in en face images can be done with high accuracy through machine learning. PMID- 30293227 TI - Pediatric endocrinology: an overview of the last decade. AB - Over the past decade, considerable progress has been made in the field of pediatric endocrinology. However, there is still a long way to go regarding the exploration of novel avenues, such as epigenetics, the changing views on the pathophysiology and derived therapy of specific disorders, and the prevention of prevalent diseases. The next decade will hopefully bring the consolidation of most of those achievements and the development of new pathways for further progress. PMID- 30293229 TI - Anti-tumor effect of endostatin in a sleep-apnea mouse model with tumor. AB - BACKGROUND: Obstructive sleep apnea (OSA) is associated with cancer incidence and mortality. The underlying mechanism is unclear. This study aims to evaluate the influence of intermittent hypoxia (IH), a novel hallmark of OSA, on tumor and to access the anti-tumor effect of endostatin on a mouse model with OSA. METHODS: The C57BL/6 J mice were randomly classified into four groups: control (normoxia) (CTL), control plus endostatin (CTL + ED), IH, and IH plus endostatin (IH + ED). Mice in IH and IH + ED groups were subjected to IH 8 h per day in 5 weeks. Lewis lung cancer cells were injected into the flank of each mouse after 1 week of IH exposure. Endostatin was also intraperitoneally injected after tumor volume reached about 200 mm3. The maximum standard uptake values (SUVmax) were detected by micro-positron emission tomography-computed tomography (micro-PET-CT) imaging prior and post-endostatin administration. Microvessel density (MVD) and vascular endothelial growth factor (VEGF) were determined for evaluating the anti-tumor effect of endostatin among the normoxia and IH conditions. RESULTS: Mice had higher SUVmax in the IH group than the CTL group (p < 0.01). When compared with mice in the CTL group, those in the IH group had significantly greater MVD values (p < 0.001). The SUVmax can be attenuated by endostatin both in the CTL (p < 0.01) and IH conditions (p < 0.001). When compared with CTL group, mice in the IH group had increased MVD values (p < 0.001) and VEGF expression both at mRNA (p < 0.05) and protein levels (p < 0.001 in western blotting results). Treatment with endostatin attenuated serum and tissue VEGF levels, lowering the MVD values. As compared to normoxia condition, the endostatin-therapeutic effects were more significant under the IH condition (p < 0.05 in western blotting results). CONCLUSIONS: Micro-PET-CT imaging is a promising non-invasive technique to evaluate the tumor metabolic characteristics under IH condition in vivo. The anti tumor effect of endostatin under IH condition is superior to that of the normoxia condition. PMID- 30293230 TI - A combination of hydroxytyrosol, omega-3 fatty acids and curcumin improves pain and inflammation among early stage breast cancer patients receiving adjuvant hormonal therapy: results of a pilot study. AB - PURPOSE: Breast cancer patients receiving hormonal therapies face risks of relapse, increased rates of cardiovascular events, and toxicities of therapy such as aromatase inhibitor (AI)-associated musculoskeletal symptoms (AIMSS). C reactive protein (CRP), a marker for inflammation, is associated with breast cancer outcomes. We evaluated whether the olive-derived polyphenol hydroxytyrosol combined with omega-3 fatty acids and curcumin would reduce CRP and musculoskeletal symptoms in breast cancer patients receiving adjuvant hormonal therapies. EXPERIMENTAL DESIGN: This prospective, multicenter, open-label, single arm, clinical trial enrolled post-menopausal breast cancer patients (n = 45) with elevated C-reactive protein (CRP) taking predominantly aromatase inhibitors to receive a combination of hydroxytyrosol, omega-3 fatty acids, and curcumin for 1 month. CRP, other inflammation-associated cytokines, and pain scores on the Brief Pain Inventory were measured before therapy, at the end of therapy and 1 month after completion of therapy. RESULTS: CRP levels declined during the therapy [from 8.2 +/- 6.4 mg/L at baseline to 5.3 +/- 3.2 mg/L (p = 0.014) at 30 days of treatment], and remained decreased during the additional 1 month off therapy. Subjects with the highest baseline CRP levels had the greatest decrease with the therapy. Pain scores also decreased during the therapy. There were no significant adverse events. CONCLUSIONS: The combination of hydroxytyrosol, omega-3 fatty acids, and curcumin reduced inflammation as indicated by a reduction in CRP and reduced pain in patients with aromatase-induced musculoskeletal symptoms. Longer studies comparing this combination to other anti-inflammatories in larger groups of patients with clinical outcome endpoints are warranted. PMID- 30293231 TI - Consensus on management of castration-resistant prostate cancer on behalf of the Urological Tumours Working Group (URONCOR) of the Spanish Society of Radiation Oncology. AB - BACKGROUND: The knowledge in the field of castration-resistant prostate cancer (CRPC) is developing rapidly, with emerging new therapies and advances in imaging. Nonetheless, in multiple areas there is still a lack of or very limited evidence, and clear guidance from clinicians regarding optimal strategy is required. METHODS: A modified Delphi method, with 116 relevant questions divided into 7 different CRPC management topics, was used to develop a consensus statement by the URONCOR group. RESULTS: A strong consensus or unanimity was reached on 93% of the proposed questions. The seven topics addressed were: CRPC definition, symptomatic patients, diagnosis of metastasis, CRPC progression, M0 management, M1 management and sequencing therapy, and treatment monitoring. CONCLUSIONS: The recommendations based on the radiation oncology experts' opinions are intended to provide cancer specialists with expert guidance and to standardise CRPC patient management in Spain, facilitating decision-making in different clinically relevant issues regarding CRPC patients. PMID- 30293232 TI - Real-world data on the efficacy and safety of weekly oral vinorelbine in breast cancer patients previously treated with anthracycline or taxane-based regimens. AB - PURPOSE: To evaluate the efficacy and safety of oral weekly vinorelbine 60 mg/m2 for metastatic breast cancer (MBC) in patients previously treated with anthracyclines or taxanes in routine clinical practice. MATERIALS AND METHODS: Fifty-five patients were enrolled in a prospective multicentre study conducted in Spain. Women >= 18 years of age with locally advanced breast cancer who were not candidates for surgical treatment with a radical intention or patients with stage IV disease, and who had received a prior taxane or anthracycline regimen were eligible for participation. RESULTS: Median age was 67 years. Median progression free survival was 3.7 months (95% CI 2.5-4.9), median overall survival 10 months (95% CI 6.6-13.5), and overall response rate and clinical benefit rate were 29.1% and 49.1%, respectively. Main grade 3 and 4 toxicities were neutropenia 9.1%, febrile neutropenia 3.6% and constipation 3.6%. In total, 86% of the patients received complete treatment without delays or dose reduction. Moreover, HER2 positive patients who received oral vinorelbine concomitantly with trastuzumab showed better response (complete response: HER2-positive 14.3% vs. HER2-negative 0%; partial response: HER2-positive 42.9% vs. HER2-negative 25.6%; p = 0.008), better disease control rate (HER2-positive 100% vs. HER2-negative 46.2%; p = 0.011), and better values for the remaining analysed variables than HER2-negative patients. CONCLUSION: Our study provides real-world data on the use of oral weekly vinorelbine, which proves an effective and well-tolerated regimen for MBC patients previously treated with taxanes or anthracyclines. Patients with HER2 positive disease could also benefit from this treatment in combination with trastuzumab. PMID- 30293233 TI - Valproate preparations for agitation in dementia. AB - BACKGROUND: Agitation has been reported in up to 90% of people with dementia. Agitation in people with dementia worsens carer burden, increases the risk of injury, and adds to the need for institutionalisation. Valproate preparations have been used in an attempt to control agitation in dementia, but their safety and efficacy have been questioned. OBJECTIVES: To determine the efficacy and adverse effects of valproate preparations used to treat agitation in people with dementia, including the impact on carers. SEARCH METHODS: We searched ALOIS - the Cochrane Dementia and Cognitive Improvement Group's Specialized Register on 7 December 2017 using the terms: valproic OR valproate OR divalproex. ALOIS contains records from all major health care databases (the Cochrane Library, MEDLINE, Embase, PsycINFO, CINAHL, LILACS) as well as from many trials databases and grey literature sources. SELECTION CRITERIA: Randomised, placebo-controlled trials that assessed valproate preparations for agitation in people with dementia. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the retrieved studies against the inclusion criteria and extracted data and assessed methodological quality of the included studies. If necessary, we contacted trial authors to ask for additional data, including relevant subscales, or for other missing information. We pooled data in meta-analyses where possible. This is an update of a Cochrane Review last published in 2009. We found no new studies for inclusion. MAIN RESULTS: The review included five studies with 430 participants. Studies varied in the preparations of valproate, mean doses (480 mg/day to 1000 mg/day), duration of treatment (three weeks to six weeks), and outcome measures used. The studies were generally well conducted although some methodological information was missing and one study was at high risk of attrition bias.The quality of evidence related to our primary efficacy outcome of agitation varied from moderate to very low. We found moderate-quality evidence from two studies that measured behaviour with the total Brief Psychiatric Rating Scale (BPRS) score (range 0 to 108) and with the BPRS agitation factor (range 0 to 18). They found that there was probably little or no effect of valproate treatment over six weeks (total BPRS: mean difference (MD) 0.23, 95% confidence interval (CI) -2.14 to 2.59; 202 participants, 2 studies; BPRS agitation factor: MD -0.67, 95% CI -1.49 to 0.15; 202 participants, 2 studies). Very low-quality evidence from three studies which measured agitation with the Cohen-Mansfield Agitation Index (CMAI) were consistent with a lack of effect of valproate treatment on agitation. There was variable quality evidence on other behaviour outcomes reported in single studies of no difference between groups or a benefit for the placebo group.Three studies, which measured cognitive function using the Mini-Mental State Examination (MMSE), found little or no effect of valproate over six weeks, but we were uncertain about this result because the quality of the evidence was very low. Two studies that assessed functional ability using the Physical Self-Maintenance Scale (PSMS) (range 6 to 30) found that there was probably slightly worse function in the valproate-treated group, which was of uncertain clinical importance (MD 1.19, 95% CI 0.40 to 1.98; 203 participants, 2 studies; moderate-quality evidence).Analysis of adverse effects and serious adverse events (SAE) indicated a higher incidence in valproate-treated participants. A meta-analysis of three studies showed that there may have been a higher rate of adverse effects among valproate-treated participants than among controls (odds ratio (OR) 2.02, 95% CI 1.30 to 3.14; 381 participants, 3 studies, low-quality evidence). Pooled analysis of the number of SAE for the two studies that reported such data indicated that participants treated with valproate preparations were more likely to experience SAEs (OR 4.77, 95% CI 1.00 to 22.74; 228 participants, 2 studies), but the very low quality of the data made it difficult to draw any firm conclusions regarding SAEs. Individual adverse events that were more frequent in the valproate-treated group included sedation, gastrointestinal symptoms (nausea, vomiting, and diarrhoea), and urinary tract infections. AUTHORS' CONCLUSIONS: This updated review corroborates earlier findings that valproate preparations are probably ineffective in treating agitation in people with dementia, but are associated with a higher rate of adverse effects, and possibly of SAEs. On the basis of this evidence, valproate therapy cannot be recommended for management of agitation in dementia. Further research may not be justified, particularly in light of the increased risk of adverse effects in this often frail group of people. Research would be better focused on effective non-pharmacological interventions for this patient group, or, for those situations where medication may be needed, further investigation of how to use other medications as effectively and safely as possible. PMID- 30293228 TI - Molecular Mechanisms Mediating Diabetic Retinal Neurodegeneration: Potential Research Avenues and Therapeutic Targets. AB - Diabetic retinopathy (DR) is a devastating complication of diabetes with a prevalence rate of 35%, and no effective treatment options. Since the most visible clinical features of DR are microvascular irregularities, therapeutic interventions often attempt to reduce microvascular injury, but only after permanent retinal damage has ensued. However, recent data suggests that diabetes initially affects retinal neurons, leading to neurodegeneration as an early occurrence in DR, before onset of the more noticeable vascular abnormalities. In this review, we delineate the sequence of initiating events leading to retinal degeneration in DR, considering neuronal dysfunction as a primary event. Key molecular mechanisms and potential biomarkers associated with retinal neuronal degeneration in diabetes are discussed. In addition to glial reactivity and inflammation in the diabetic retina, the contribution of neurotrophic factors, cell adhesion molecules, apoptosis markers, and G protein signaling to neurodegenerative pathways warrants further investigation. These studies could complement recent developments in innovative treatment strategies for diabetic retinopathy, such as targeting retinal neuroprotection, promoting neuronal regeneration, and attempts to re-program other retinal cell types into functional neurons. Indeed, several ongoing clinical trials are currently attempting treatment of retinal neurodegeneration by means of such novel therapeutic avenues. The aim of this article is to highlight the crucial role of neurodegeneration in early retinopathy progression, and to review the molecular basis of neuronal dysfunction as a first step toward developing early therapeutic interventions that can prevent permanent retinal damage in diabetes. ClinicalTrials.gov: NCT02471651, NCT01492400. PMID- 30293234 TI - Occupational therapy delivered by specialists versus non-specialists for people with schizophrenia. AB - BACKGROUND: Schizophrenia is a severe mental health condition that is characterised by positive symptoms, such as hallucinations and delusions; negative symptoms, such as flattened affect, thought disorder (disrupted speech), and lack of motivation; and cognitive symptoms, such as problems with memory and attention. Schizophrenia can occur as an isolated episode, or as a recurring cycle of remission and relapse, and is associated with impairment in psychosocial and occupational functioning.Although antipsychotic drugs are the main treatment for people with schizophrenia, in most countries mental health services usually provide a range of add-on interventions, including occupational therapy. This is a complex intervention designed to support and enable continued participation in daily life through engagement in activities and occupations meaningful to the individual. Occupational therapists are professionals trained to deliver therapy where the emphasis is on improving occupational function and participation rather than treating symptoms, and uses a wide range of methods based on the needs of individuals. However, similar interventions may also be delivered by staff not trained as occupational therapists. OBJECTIVES: To examine the effects of occupational therapy delivered by occupational therapists compared to occupational therapy delivered by any other person for people with schizophrenia. SEARCH METHODS: We searched the Cochrane Schizophrenia Group's Study-Based Register of Trials (including trial registers) on 4 November 2016 and 26 July 2018. SELECTION CRITERIA: All randomised controlled trials evaluating the functional or clinical outcomes of occupational therapy, or both, for people with schizophrenia delivered by occupational therapists compared with occupational therapy for people with schizophrenia delivered by anyone other than occupational therapists. DATA COLLECTION AND ANALYSIS: Review authors independently inspected citations, selected studies, extracted data, and appraised study quality. MAIN RESULTS: The search yielded 1633 records. Of these, we retrieved 17 full-text reports (14 studies) for further scrutiny, which we subsequently excluded as they did not meet our inclusion criteria. AUTHORS' CONCLUSIONS: Currently there are no randomised controlled trials comparing delivery of occupational therapy for people diagnosed with schizophrenia by occupational therapists with delivery of similar interventions by anyone other than occupational therapists. Research studies employing methodologically robust trial designs are needed to establish whether or not there are better outcomes for people with a diagnosis of schizophrenia with occupational therapy that is delivered by trained occupational therapists. PMID- 30293235 TI - Adjacent skin rotation flap for large defect in primary breast tumor. AB - BACKGROUNDS: Surgical resection of large primary breast tumor often results in large chest wall defects. The purpose of this study is to evaluate the feasibility of using adjacent skin rotation (ASR) flap in patients with giant primary breast tumor. METHODS: A total of 26 giant primary breast tumor patients treated with ASR flap were included in this study. The postoperative conditions, including operating time, blood loss, length of hospital stay, and clinical complications were observed. Meanwhile, the information on 17 breast tumor patients treated with transverse rectus abdominis myocutaneous (TRAM) flap were collected and assigned to a control group. RESULTS: The mean defect size after mastectomy was 16.7 * 13.4 cm, while the median follow-up period was 13 months after surgery. A total of 15.4% patients had developed with local complications, and one of them had more than one complication. When comparing the postoperative outcomes, statistically significant differences were found between the two groups with respect to operating time, blood loss, and length of hospital stay (P < 0.001). CONCLUSIONS: ASR flap is a reliable technique for immediate reconstruction of massive chest wall defects in patients with giant primary breast tumor. PMID- 30293236 TI - Comparing two blood culture systems for the detection of bacterial contamination in platelet concentrates. AB - BACKGROUND: The transfusion of platelet concentrates (PCs) contaminated with bacteria may cause serious, and even fatal, septic reactions in patients. The aim of this study was to compare the VersaTREK with the BACTEC FX automated culture systems for screening bacterial contamination, directly after the delay of 24 hours of preparation to obtain the final pooled buffy coat PCs, to prevent transfusion-transmitted bacterial infections. STUDY DESIGN AND METHODS: Seven bacterial strains were each inoculated into five replicate pooled buffy coat PCs at approximately 100 colony-forming units/unit, and 5- or 10-mL samples were inoculated into duplicate aerobic culture bottles. The time and detection rates were compared between BACTEC FX, as a reference method, and VersaTREK. RESULTS: Time to detection was significantly shorter using VersaTREK for most species detected by both systems for the volumes tested. Of 70 VersaTREK cultures, 69 (98.57% detection rate) were positive after 24 hours of incubation with the 5-mL sample. In contrast, the BACTEC FX system detected all positive samples in PCs for the volume of 10 mL, although seven samples were false negatives for the 5-mL volume. CONCLUSION: The VersaTREK system compared favorably to the BACTEC FX system for 5-mL volumes (p < 0.05) and could be considered a potential method for detecting bacterial contamination in PC samples directly after 24 hours of preparation of the final pooled buffy coat PCs. PMID- 30293237 TI - In-situ microbially induced Ca2+ -alginate polymeric sealant for seepage control in porous materials. AB - This paper presents a novel approach of using in-situ microbially induced Ca2+ alginate polymeric sealant for seepage control in porous materials. This process comprises two steps: (i) generation of insoluble calcium carbonate inside the pores of porous materials (such as sand) through a microbially induced carbonate precipitation (MICP) process in-situ and (ii) injection of sodium alginate for in situ gelation via reaction between alginate and Ca2+ ions. The experimental results showed that the hydraulic conductivity/permeability of sand decreased with the increase in alginate concentration. When 5% alginate was used with a CaCO3 concentration of 0.18 g g-1 sand, the permeability of the alginate-treated sand reduced from 5.0 * 10-4 to 2.2 * 10-9 m s-1 . The scanning electron microscopy images revealed that a film-type coating was formed around sand particles with spherical round crystals embedded. Furthermore, the in-situ formed Ca-alginate polymeric sealant can also be used for the removal of Cu2+ ion and suspended particles from contaminated water by more than 90%. Built on the current research, the envisioned practical application of the proposed method may include clogging fractured rock, reducing seepage and prevent piping through dams, excavation dewatering, and forming barriers for remediating specific contaminants. PMID- 30293238 TI - Estimating contribution of rare non-coding variants to neuropsychiatric disorders. AB - Owing to recent advances in DNA sequencing technology, a number of large-scale comprehensive analyses of genetic variations in protein-coding regions (i.e., whole-exome sequencing studies), have been conducted for neuropsychiatric and neurodevelopmental disorders, such as autism spectrum disorders, intellectual disability, and schizophrenia. These studies, especially those focusing on de novo (newly arising) mutations and extremely rare variants, have successfully identified previously unrecognized disease genes/mutations with a large effect size and deepen our understanding of the biology of neuropsychiatric diseases. Along with the continuously dropping sequencing cost, now the target of sequencing studies is expanding from the exome to the whole human genome. Several pioneering works have provided important insights into the contribution of rare non-coding variants to neuropsychiatric diseases. At the same time, these studies highlight need for further larger sample sizes and improvement in annotation of non-coding regulatory variants. In this review, key findings from recent studies as well as likely future directions are overviewed.

PMID- 30293239 TI - Short-term outcomes of pleurectomy decortication and extrapleural pneumonectomy in mesothelioma. AB - BACKGROUND/OBJECTIVES: We evaluated postoperative mortality and complications after extrapleural pneumonectomy (EPP) and pleurectomy decortication (P/D) to better understand their effectiveness in malignant pleural mesothelioma (MPM). METHODS: A meta-analysis was done to evaluate 30-day mortality and postoperative complications. In addition, in-patients data of 500 eligible patients with MPM who underwent EPP or P/D was extracted from the New York Statewide Planning and Research Cooperative System (SPARCS). Multivariate analyses and propensity matching were used to compare in-hospital mortality and postoperative complications in EPP vs P/D. RESULTS: The meta-analysis showed a statistically significant difference in 30-day mortality (5% [95% CI: 4-6] vs P/D 2% [95% CI: 1 3]), proportion of complications (46% [95% CI: 36-56] vs 24% [95% CI: 15-34]) and postoperative arrhythmias (20% [95% CI: 12-31] vs 5% [95% CI: 2-8]) for EPP vs P/D. In-hospital mortality (OR adj : 2.6; 95% CI: 0.86-7.75) and postoperative complications (OR adj : 1.1; 95% CI: 0.68-1.86) were not different in EPP compared with P/D while supraventricular arrhythmia was significantly more frequent after EPP vs P/D (OR adj : 5.2; 95% CI: 2.34-11.33). CONCLUSIONS: Postoperative mortality, postoperative complications, and particularly supraventricular arrhythmia are less frequent after P/D vs EPP. P/D, a less invasive surgery, may provide a better option when technically feasible for patients with MPM. PMID- 30293241 TI - Does intra-operative margin assessment improve margin status and re-excision rates? A population-based analysis of outcomes in breast-conserving surgery for ductal carcinoma in situ. AB - BACKGROUND AND OBJECTIVES: Using a 2 mm margin criteria, we evaluated the effect of intra-operative margin assessment on margin status and re-excisions following breast-conserving surgery (BCS) for ductal carcinoma in situ (DCIS). METHODS: We identified patients undergoing BCS for DCIS from a prospective, population-based database. Multivariable logistic regression was used to determine the effect of specimen mammography, ultrasound and macroscopic assessment by a pathologist on margins and re-excision rates. RESULTS: In 588 patients, 52% (95% confidence interval [CI], 48%-56%) had positive margins (<2 mm), 39% (95% CI, 35%-43%) had a re-excision and 15% (95% CI, 12%-18%) had completion mastectomy. There were few re-excisions for margins >=2 mm (2%). Adjusting for confounders, any margin assessment versus wire localization alone did not reduce positive margins (odds ratio [OR], 0.75; P = 0.202) or re-excisions (OR, 1.14; P = 0.564), however both outcomes varied by type of technique ( P < 0.001). Individually, only macroscopic assessment by pathologist reduced positive margins (OR, 0.54; P = 0.002) and re excisions (OR, 0.61; P = 0.036). CONCLUSIONS: Despite adherence to a 2 mm margin criteria, re-excision rates remain high following BCS for DCIS, with 39% converted to mastectomy when re-excision is required. Intra-operative margin assessment does not appear to reduce re-excisions; in particular, surgeons should be aware of the limitations of specimen mammography for margin assessment in DCIS. PMID- 30293242 TI - Hypertension and diabetes mellitus are not associated with worse renal functional outcome after partial nephrectomy in patients with normal baseline kidney function. AB - OBJECTIVE: To analyze the association of hypertension and/or diabetes mellitus on renal function after partial nephrectomy in patients with normal baseline kidney function. METHODS: We identified 453 patients with baseline estimated glomerular filtration rate >=60 that underwent robotic partial nephrectomy for a cT1 renal mass from 2008 to 2014 using a multi-institutional database. The association between estimated glomerular filtration rate and time (pre-partial nephrectomy to 24 months post-partial nephrectomy) was compared between 269 (59.4%) patients with preoperative hypertension and/or diabetes mellitus and 184 (40.6%) patients with neither hypertension nor diabetes mellitus using a multivariable model adjusting for confounders. RESULTS: The estimated glomerular filtration rate significantly decreased over time for both groups compared with baseline (average units/month: 1.8974 hypertension/diabetes mellitus, 1.2163 no hypertension/diabetes mellitus; P < 0.0001), and the estimated glomerular filtration rate decrease per month reduced over time (P < 0.0001). The estimated glomerular filtration rate began to increase at approximately 12 months for the hypertension/diabetes mellitus group, and at approximately 18 months for the no hypertension/diabetes mellitus group. Although a greater initial decline in the estimated glomerular filtration rate after partial nephrectomy was observed for the hypertension/diabetes mellitus group (0.68 units/month), this was not statistically significant (P = 0.0842); and while the rate of recovery from this decline was faster for the hypertension/diabetes mellitus group, this also was not statistically significant (P = 0.0653). The predicted estimated glomerular filtration rate was similar (83 mL/min/1.73 m2 ) for both groups 24 months after partial nephrectomy. CONCLUSIONS: There seems to be no significant association between hypertension, diabetes mellitus and renal functional outcome after partial nephrectomy in patients with normal baseline glomerular filtration rate. Renal function declines after partial nephrectomy, but then it recovers, irrespective of the presence of hypertension or diabetes mellitus. PMID- 30293243 TI - Safety and feasibility of early postmastectomy discharge and home drain care in a low resource setting. AB - BACKGROUND: Early postmastectomy discharge with a drain in place is standard practice in most developed countries. Its feasibility has not been evaluated in low resource settings like Nigeria. METHODS: Consenting patients undergoing mastectomy were discharged on the third postoperative day and assessed as outpatients for wound complications as well as their experience at home. Wound outcomes were compared with patients who had traditional long stay. RESULTS: Forty-five of the 58 patients who had a mastectomy during the study period participated in the early discharge program (77.6%). Of these, four patients (8.9%) had drain malfunction, seroma occurred in eight patients (17.8%), eight patients (17.8%) had wound infection, and six patients (13.3%) had flap necrosis. There was no readmission. Compared with long stay patients, postoperative stay was significantly shorter (3 vs 11 days; P < 0.01) with significant cost savings, while complication rates were not statistically different. All the patients in the early discharge group were confident operating their drains and preferred early discharge. Being around relatives, reduced cost, and fear of the hospital environment were common reasons cited for their preference. CONCLUSION: Our results support the implementation of an early postmastectomy discharge program in a low resource setting. PMID- 30293244 TI - Primary tumors of the hand: Functional and restorative management. AB - Primary malignant tumors of the hand are rare. Most cases present to clinics unaffiliated with cancer centers, making it incumbent on all hand surgeons to understand the pathology indicative of malignancy and the proper course of treatment of hand neoplasms. In this review, we report, based on tumor type, the anatomical considerations, proper management, staging, surgical approaches, reconstructive considerations, and long-term surveillance of primary malignant tumors of the hand. PMID- 30293245 TI - Single-stage repair of obliterated anterior urethral strictures using buccal mucosa graft and dorsal penile skin flap. AB - OBJECTIVE: To present a single-stage repair of obliterative urethral strictures by simultaneous use of a buccal mucosa graft and longitudinal dorsal penile skin flap. METHODS: Between February 2007 and October 2016, 51 patients with obliterative anterior urethral stricture underwent single-stage substitution urethroplasty. A buccal mucosa graft was harvested and fixed to the corpora cavernosa as the dorsal part of the neourethra, and a vascularized dorsal penile skin flap was created, transposed ventrally and sutured to the buccal mucosa graft to form ventral part of the neourethra. RESULTS: The follow-up period was 12-129 months (mean 49 months). The mean age of the patients was 48 years (range 15-71 years). The mean length of the obliterated urethral segment, measured during the operative procedure, was 5.2 cm. The etiology of strictures was: unknown, hypospadias and trauma in 19, 27 and five patients, respectively. Five patients were lost to follow up, and 46 patients were analyzed for the outcome. At the end of the follow-up period, recurrence of the stricture occurred in seven (15.2%) patients, whereas 39 (84.8%) patients did not develop stricture. An additional three (6.5%) patients developed fistula, resulting in overall successful voiding in 36 (78.3%) patients. CONCLUSIONS: A combined buccal mucosa graft and longitudinal dorsal penile skin flap could be a good choice for one stage substitution urethroplasty in complex obliterative urethral strictures, with an acceptable complication rate.

AB - Reconstructive technologies have expanded to include the use of virtual surgical planning (VSP) and computer-aided design and manufacturing (CAD-CAM), and 3 Dimensional printing. The advantages of VSP over traditional techniques are highlighted in many scenarios: (a) delayed reconstruction, (b) maxillary reconstruction, (c) placement of dental implants, and (d) precision guided oncology. Microsurgery is undergoing a paradigm shift with virtual planning at its foreground. Herein, we describe the versatile uses for CAD-CAM and key operative steps. PMID- 30293248 TI - Contribution of next generation sequencing in pediatric practice in Lebanon. A Study on 213 cases. AB - BACKGROUND: According to the Catalogue of Transmission Genetics in Arabs, less than half of diseases reported in Lebanese patients are mapped. In the recent years, Next Generation Sequencing (NGS) techniques have significantly improved clinical diagnosis, compared to traditional sequencing methods. METHODS: A total of 213 analyses by NGS (167 by whole exome sequencing (WES) and 46 by multigene panels tests) were performed on pediatric patients across different regions of Lebanon over a period of two years (December 2015-December 2017). RESULTS: Neurological disorders were the most frequent referral demand for both WES and gene panels (122/213). Pathogenic, likely pathogenic, or variants of unknown significance were identified in 69.5% of the WES and panel patients combined. Over half of the patients with such variants had an autosomal recessive disorder. A definite molecular diagnosis (pathogenic or likely pathogenic variants) was achieved in 34.1% and 47.8% of the patients studied by WES and the multigene panels, respectively. Thirty-three novel variants were found in the cases that were molecularly solved; 26 of these being identified by WES and seven by the multigene panels. In three consanguineous families, autosomal recessive inheritance of genes previously reported as showing dominant inheritance patterns were found. Biallelism was found in six cases, digenism in four cases, and one case was trigenic. CONCLUSION: Our study thus suggests that NGS tools are valuable for an improved clinical diagnosis, and highlights that the increased adoption of such techniques will significantly further improve our understanding of the genetic basis of inherited diseases in Lebanon. PMID- 30293249 TI - Accuracy of actual resected liver volume in anatomical liver resections guided by 3-dimensional parenchymal staining using fusion indocyanine green fluorescence imaging. AB - BACKGROUND: The aim of this study was to assess the accuracy of actual resected liver volume (ARLV) in anatomical liver resections (ALRs) guided by 3-dimensional parenchymal staining using fusion indocyanine green fluorescence imaging (IGFI). METHODS: Patients eligible for hepatic resection were enrolled in the current study from January 2016 to November 2017. All patients underwent surgery planning based on Medical Image Three-Dimensional Visualization System (MI-3DVS) before the operation, in which predicted resected liver volumes (PRLVs) were calculated. Under 3-dimensional guidance by fusion IGFI, ALRs were performed and ARLVs were measured. Simple linear regression, intra-class correlation coefficient (ICC) and Bland-Altman analysis were used to evaluate the relationship and agreement between PRLV and ARLV. RESULTS: Of the 27 patients who achieved valid demarcation by fusion IGFI, 12 (44.4%) received hemihepatectomy, while 10 (37.0%) and five (18.5%) underwent sectionectomy and segmentectomy, respectively. The relationship and agreement between PRLV (481.37 +/- 189.47 cm3) and ARLV (450.57 +/- 205.19 cm3) were then evaluated. The simple regression equation obtained was PRLV = 0.874 * ARLV + 87.75 (R = 0.946; P = 0.000). Meanwhile, ARLV (ICC = 0.943) achieved an excellent agreement with PRLV ( P < 0.001); 25 of 27 dots were in the range of 95% confidence interval in Bland-Altman analysis. CONCLUSIONS: In the study, these findings validated the consistency between PRLV calculated by MI 3DVS and ARLV guided by fusion IGFI, which proved that IGFI can accurately guide anatomical hepatectomy. Generally, fusion IGFI can provide a valid, feasible and accurate demarcation line, which can confer precision to hepatic resection. PMID- 30293251 TI - Deficiency of Sphingosine-1-Phosphate Receptor 2 (S1P2) Attenuates Bleomycin Induced Pulmonary Fibrosis. AB - Sphingosine 1-phosphate (S1P) levels are often found to be elevated in serum, bronchoalveolar lavage, and lung tissue of idiopathic pulmonary fibrosis patients and experimental mouse models. Although the roles of sphingosine kinase 1 and S1P receptors have been implicated in fibrosis, the underlying mechanism of fibrosis via Sphingosine 1-phosphate receptor 2 (S1P2) has not been fully investigated. Therefore, in this study, the roles of S1P2 in lung inflammation and fibrosis was investigated by means of a bleomycin-induced lung fibrosis model and lung epithelial cells. Bleomycin was found to induce lung inflammation on day 7 and fibrosis on day 28 of treatment. On the 7th day after bleomycin administration, S1P2 deficient mice exhibited significantly less pulmonary inflammation, including cell infiltration and pro-inflammatory cytokine induction, than the wild type mice. On the 28th day after bleomycin treatment, severe inflammation and fibrosis were observed in lung tissues from wild type mice, while lung tissues from S1P2 deficient mice showed less inflammation and fibrosis. Increase in TGF-beta1-induced extracellular matrix accumulation and epithelial-mesenchymal transition were inhibited by JTE-013, a S1P2 antagonist, in A549 lung epithelial cells. Taken together, pro-inflammatory and pro-fibrotic functions of S1P2 were elucidated using a bleomycin-induced fibrosis model. Notably, S1P2 was found to mediate epithelial-mesenchymal transition in fibrotic responses. Therefore, the results of this study indicate that S1P2 could be a promising therapeutic target for the treatment of pulmonary fibrosis. PMID- 30293250 TI - Ex vivo indocyanine green fluorescence imaging for the detection of lymph node involvement in advanced-stage ovarian cancer. AB - BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate the role of indocyanine green (ICG) fluorescence imaging (FI) for the ex vivo detection of metastatic lymph nodes (LNs) in advanced stage ovarian cancer (AOC). METHODS: Paraffin-embedded LNs from patients included in a previous ICG-FI study (Protocol NCT01834469) were further assessed for fluorescence. Intravenous injection of ICG was delivered intraoperatively. Tumor-to-background ratios (TBRs) were calculated. RESULTS: A total of 675 LNs from 19 patients were analyzed. The mean LN number per patient was 29.3 (median: 24; range 2-77). Seventy-three LNs were malignant (10.8%), 602 were benign (89.2%). The mean TBR of all LNs was 1.5 (SD 0.8). With a cut-off TBR of 1.3, the sensitivity, specificity, positive predictive, and negative predictive values of ICG-FI for retroperitoneal LNs were 80%, 41%, 2.8%, and 99%, respectively. On univariate analysis, only the fluorescence ratio (TBR >= 1.3) was correlated with malignancy at pathology (P = 0.03). No predictive factors of pathological LN status were found on multivariate analysis. CONCLUSIONS: Ex vivo ICG-FI of retroperitoneal LNs in AOC had good sensitivity but poor specificity. However, its high negative predictive value could make it an appropriate complementary tool to focus pathological analysis on fluorescent LNs. PMID- 30293252 TI - Differential Gene Expression Common to Acquired and Intrinsic Resistance to BRAF Inhibitor Revealed by RNA-Seq Analysis. AB - Melanoma cells have been shown to respond to BRAF inhibitors; however, intrinsic and acquired resistance limits their clinical application. In this study, we performed RNA-Seq analysis with BRAF inhibitor-sensitive (A375P) and -resistant (A375P/Mdr with acquired resistance and SK-MEL-2 with intrinsic resistance) melanoma cell lines, to reveal the genes and pathways potentially involved in intrinsic and acquired resistance to BRAF inhibitors. A total of 546 differentially expressed genes (DEGs), including 239 up-regulated and 307 down regulated genes, were identified in both intrinsic and acquired resistant cells. Gene ontology (GO) analysis revealed that the top 10 biological processes associated with these genes included angiogenesis, immune response, cell adhesion, antigen processing and presentation, extracellular matrix organization, osteoblast differentiation, collagen catabolic process, viral entry into host cell, cell migration, and positive regulation of protein kinase B signaling. In addition, using the PANTHER GO classification system, we showed that the highest enriched GOs targeted by the 546 DEGs were responses to cellular processes (ontology: biological process), binding (ontology: molecular function), and cell subcellular localization (ontology: cellular component). Ingenuity pathway analysis (IPA) network analysis showed a network that was common to two BRAF inhibitor-resistant cells. Taken together, the present study may provide a useful platform to further reveal biological processes associated with BRAF inhibitor resistance, and present areas for therapeutic tool development to overcome BRAF inhibitor resistance.

AB - Objective: To explore the clinical characteristics of the complication of brain abscesses after cerebrospinal fluid rhinorrhea repairment. Methods: A retrospective analysis was conducted on 149 patients undergone endoscopic repairment of cerebrospinal fluid rhinorrhea from October 2007 to October 2017 in Department of Otorhinolaryngology Head and Neck Surgery, Tianjin HuanHu Hospital. The clinical characteristics and treating methods of 3 brain abscess cases were analyzed. Results: Of the 149 patients accepted the endoscopic repairment of cerebrospinal fluid rhinorrhea, 3 cases were complicated with postoperative brain abscesses, which showed as frontal lobe abscess by strengthened head MRI. The incidence of abscess was 2.0%. Abscess formation time was within 10 d after surgery. One case was treated with antibiotic and reducing intracranial pressure, while other 2 cases were treated with puncture drainage. After following-up of 1 to 24 months, these 3 cases had no recurrence of cerebrospinal fluid rhinorrhea or abscess. Conclusions: The complication of brain abscess formation after endoscopic repairment of cerebrospinal fluid rhinorrhea is more common in frontal lobe, which may take place within 7-10 d postoperatively. Conservative treatment is the first choice. Under the condition of obvious symptoms and pus cavity fusion, puncture drainage can be performed. PMID- 30293254 TI - [Screening for hotspot mutations associated with genetic hearing impairment in pregnant women and subsequent prenatal diagnosis in high risk pregnancies]. AB - Objective: To screen for hotspot gene mutations associated with genetic deafness in Chinese pregnant women, and to perform risk assessment and prenatal diagnosis in high-risk families. Methods: Between November 2012 and October 2017, 26 117 pregnant women were screened by molecular hybridization microarray for 9 hot-spot mutations in 4 hereditary deafness related genes (GJB2 c. 35 del G, c. 176_191 del 16 bp, c. 235 del G, c. 299_300 del AT, GJB3 c. 538 C>T, SLC26A4 c. 2168 A>G, IVS 7-2 A>G, mitochondrial DNA 12S rRNA m. 1494 C>T, m. 1555 A>G). Genotype analysis was carried out in husbands of women carrying mutations, and prenatal diagnosis was carried out in the fetuses with high risk of deafness. Results: Among all women tested, 1 208(4.63%) were carriers of genetic deafness mutations, 7 with hearing impairment were affected by homozygous or compound heterozygous mutations, 51 were mitochondrial gene mutation carriers, 103 were carriers of GJB3 c. 538 C>T heterozygous mutation, 1 026 were carriers of GJB2 or SLC26A4 heterozygous mutations, and 21 carried heterozygous mutations in two genes simultaneously. In 394 families, the husbands accepted gene sequence testing, and 27 in which were determined as carriers of mutations in identical genes as their wives. Among which, 18 families received prenatal diagnosis, and 5 fetuses were diagnosed as hereditary deafness. In 9 families who did not receive prenatal diagnosis, 1 neonate was diagnosed as compound heterozygote after delivery. Conclusion: In order to prevent birth defects with congenital hearing problems, it is effective to provide screening for hotspot mutations in pregnant women and to perform prenatal diagnosis on high risk pregnancies. PMID- 30293256 TI - [The efficacy of ansa cervicalis anterior root for unilateral recurrent laryngeal nerve injury]. AB - Objective: To discuss the long-term efficacy of laryngeal reinnervation using the anterior root of the ansa cervicalis in the treatment of unilateral vocal fold paralysis (UVFP) caused by thyroid surgery. Method: From January 2010 to January 2016, a total of 39 UVFP patients who underwent ansa cervicalis anterior root-to recurrent laryngeal nerve (RLN) anastomosis and who had suffered nerve disfunction for 6 to 24 months were enrolled as UVFP group.Another 39 age and gender matched normal subjects served as control group. Videostroboscopy, vocal function assessment (acoustic analysis, perceptual evaluation and maximum phonation time), and laryngeal electromyography were performed preoperatively and postoperatively for assessing surgery efficacy. Paired sample t test was used for statistical analysis. Result: Videostroboscopic reports indicated that the glottic closure, vocal fold edge, vocal fold position, phase symmetry and regularity were significantly improved in the UVFP group (P<0.01, respectively, postoperative vs. preoperative)and showed no statistical differences compared to the control group (P>0.05, respectively). Both the postoperative GRBAS assessment and acoustic parameters were also significantly improved in the UVFP group, Pre operative acoustic parameters/Post-operative acoustic parameters were 1.68+/ 0.82/0.39+/-0.27, 10.08+/-2.56/4.58+/-2.96, 0.203+/-0.216/0.018+/-0.038, 5.96+/ 1.92/17.42+/-4.11(P<0.01, respectively) and Pre-operative acoustic parameters/Post-operative acoustic parameters were 0.39+/-0.27/0.32+/-0.19, 4.58+/-2.96/3.32+/-1.27, 0.018+/-0.038/0.014+/-0.027, 17.42+/-4.11/18.76+/-5.29, which showed no statistical differences compared to the control group (P>0.05, respectively). Conclusion: Delayed laryngeal reinnervation with the anterior root of ansa cervicalis, it can restore the physiological laryngeal phonatory function to the normal or a nearly normal voice quality, which is a feasible and effective approach for the treatment of thyroid surgery-related UVFP. PMID- 30293257 TI - [Application of gastric pull up and complex laryngotracheal flap to reconstruct the circumferencial defect after resection of the hypopharyngeal and cervical esophageal cancers]. AB - Objective: To evaluate the efficacy of gastric pull-up and complex laryngotracheal flap in reconstruction for circumferencial defects after resection of hypopharyngeal and cervical esophageal cancers. Methods: A total of 163 cases (152 males, 11 females) with circumferencial defect after resection of hypopharyngeal and cervical esophageal cancers received reconstructive surgeries by gastric pull-up (42 cases) and complex laryngo-tracheal flaps (121 cases), of them 115 cases simultaneously underwent unilateral neck dissection and 20 cases had bilateral neck dissection. Postoperative radiotherapy was used in 67 cases, with a dosage of 40-60 Gy. Results: There were 127 (77.9%) cases with positive metastatic lymph nodes. Of 42 patients with gastric pull-up reconstruction, 39 cases (92.8%) recovered the function of oral swallowing after operation, and 8 cases with cervical esophageal cancer recovered the functions of oral swallowing and speech after gastroesophageal anastomosis reconstruction. There were 3 (7.1%) cases died of surgery and 8 cases with surgical complications. Reconstruction of upper digestive tract with combined laryngotracheal flap was successful in all 121 cases, with recovered oral swallowing function after operation. No patient died of surgery but 24 cases had complications, mainly pharynx skin fistula or wound infection, which were cured by conservative treatments. The 1-, 3- and 5 year survival rates for 163 patients were 69.8%, 50.5% and 34.3%, respectively. The independent factors for prognosis included T4 (P<0.001) and N+ (P=0.042). Conclusions: The complex of laryngotracheal flap with pectoralis major myocutaneous flap is suitable for most advanced hypopharyngeal cancer after resection of the tumor and reconstruction of circumferencial defect. It is simple technology, low and slight complication rate. The minority is not suitable for the application of pectoralis major myocutaneous flap can be used instead of free anterolateral thigh flap. Gastric pull-up for reconstruction of upper digestive tract is suitable for most patients with cervical esophageal cancer and hypopharyngeal carcinoma invading the cervical esophagus who are not suitable for laryngotracheal flap reconstruction, with good swallowing function after surgery. However, it is prudent to choose operative indications because of serious surgical trauma and risks for complications. PMID- 30293258 TI - [Clinical characteristic and prognostic analyses of 117 cases of head and neck mucosal melanoma]. AB - Objective: To study the clinical characteristics of mucosal melanoma in the head and neck, including the risk factors affecting distant metastasis, recurrence and survival rate, and to provide the basis for the individualized treatment of mucosal melanoma in the head and neck. Methods: The clinical data of 117 cases of mucosal melanoma in the head and neck treated from January 2004 to June 2016 in Beijing Tongren Hospital were analyzed retrospectively, and the risk factors affecting the prognosis, distant metastasis and local recurrence were analyzed.Kaplan-Meier analysis was used for survival analysis, and Log-Rank test was used for comparison between groups. Results: The follow-up time was 5-139 months, with a median of 32 months, and the median survival time was 34 months.The 3 and 5 year cumulative survival rates were 47.0% and 25.0%, respectively.Local recurrence occurred in 27 patients (23.1%), and distant metastasis in 37 cases (31.6%). After the operation, 50 patients received radiotherapy.Multiple factor Cox regression analysis showed that distant metastasis, AJCC staging, and two operations were risk factors affecting survival (P<0.05), and immunologic/targeted therapy was a protective factor affecting survival prognosis(P=0.008). Postoperative radiotherapy and distant metastasis were important factors affecting recurrence (P<0.05). AJCC staging, pigmentation, and postoperative recurrence were risk factors for distant metastasis (P<0.05). Conclusion: The 3 and 5 year survival rates of primary mucosal melanoma in head and neck are low, and the incidence of local recurrence and distant metastasis are high. Surgery is the first choice and the integrity of the initial operation has an important impact on the prognosis of the patients. Postoperative adjuvant radiotherapy is recommended to improve the local control rate, and immunotherapy and targeted therapy should be applied in time to improve survival. PMID- 30293259 TI - [Experimental study on dendritic cells modified by dust mite allergen gene in the treatment of allergic rhinitis in mouse]. AB - Objective: To explore the therapeutic effects of dendritic cells (DC) modified by the dust-mite-allergen(Der p1) gene on mouse model of allergic rhinitis (AR). Methods: DC modified by the Der p1 gene (Der p1-DC) were prepared.Using random number table, 24 Balb?c mice were divided into four groups: immature DC (imDC)/AR group, dexamethasone/AR group, Der p1-DC/AR group and control group, with 6 mice in each group.AR mouse model was built with Der p1 and the mouse model of AR was established.The AR mice were respectively given by abdominal injection of Der p1 DC, imDC and dexamethasone.Normal control mice were treated with physiologic saline.ELISA method was used for determining the content of IgE, IgG1and histamine in blood.The relative expression of mRNA of IL-4 and IL-13 on nasal mucosa with protein was analyzed by RT-PCR and Westen blot methods.All the data were statistically analyzed by SPSS 19.0 statistical software, and the variance analysis was used in multiple groups of average samples. Results: The contents of IgE, IgG1 and histamine in the mice of Der p1-DC/AR group were lower than those in imDC/AR group ((0.560+/-0.110) OD 450 nm vs (1.150+/-0.280) OD 450 nm, (0.690+/-0.054) OD 450 nm vs (0.920+/-0.125) OD 450 nm, (4 145+/-670) pg/ml vs (7 685+/-669) pg/ml, t value was 4.80, 4.14, 9.16, respectively, all P<0.05), and the expression of IL-4 and IL-13 on nasal mucosa in Der p1-DC/AR group was remarkedly lower than those in imDC/AR group (0.41+/-0.25 vs 1.59+/-1.02, 0.26+/ 0.01 vs 1.10+/-0.09, t value was 2.75, 22.72, respectively, all P<0.05). There was no statistically significant difference between the mice treated with Der p1 DC and dexamethasone group. Conclusions: The results showed that Der p1-DC could reduce inflammation in AR mice and decrease the expression of IL-4 and IL-13. It suggested that Der p1-DC can be used in the immunotherapy of AR mouse. PMID- 30293260 TI - [Impact of blood eosinophils on clinical effect of endoscopic sinus surgery for chronic rhinosinusitis with nasal polyps]. AB - Objective: To investigate the effect of blood eosinophils on clinical effect of endoscopic sinus surgery for chronic rhinosinusitis with nasal polyps (CRSwNP). Methods: From March 2011 to March 2016, 72 cases with CRSwNP were treated by endoscopic sinus surgery in Department of Otorhinolaryngology Head and Neck Surgery, Peking University People's Hospital. The clinical records were retrospectively reviewed, and the cases were divided into eosinophilia elevated and non-elevated group according to blood eosinophils, and nasal polyps were evaluated for histopathology eosinophil count. Statistical analysis was performed to compare two groups' pre- and post-operative symptoms of VAS score, sinus computed tomography (CT) scans scores according to the Lund-Mackay system and the outcome of surgery. Both groups' factors that might have affected their outcome were analyzed by t-test, Chi square, Pearson Correlation Coefficient and Willcoxon rank sum test. Results: Seventy two cases were followed up from 24 to 78 months.The average follow-up time was 56 months. The VAS score in the eosinophilia elevated group (n=16) was higher than that in the non-elevated group(n=56), and the difference was statistically significant (11.44+/-7.13 vs 4.98+/-5.64, t=3.726, P<0.05). The control of symptoms in the peripheral blood eosinophilia elevated group was less than that in the non-elevated group, and the difference was statistically significant (Z=-1.979, P<0.05). There was a positive correlation between eosinophil counts in peripheral blood and tissues of 72 cases (r=0.429, P<0.05).

AB - Objective: To evaluate the clinical features, treatments and prognoses of malignant salivary gland tumors of the larynx. Methods: A total of 14 patients with malignant salivary gland tumors of the larynx diagnosed and treated in our hospital between 2003 and 2014 were analyzed retrospectively, and were compared with 62 patients from the Surveillance, Epidemiology, and End Results: (SEER) database of American for survival rates. Results Among 14 patients from our hospital, 9 males and 5 females, with a median of 66.5 years old; 8 patients with adenoid cystic carcinoma, 4 with mucoepidermoid carcinoma and 2 with adenocarcinoma; supraglottic, glottic and 4 subglottic malignancies respectively accounting for 5, 5 and 4 cases; 8 cases treated with surgery, 5 with surgery and postoperative radiotherapy and/or chemotherapy, and 1 with radiotherapy alone. The 14 patients showed a three-year overall survival rate of 50.0% and a five year overall survival rate of 42.9%, respectively in contrast with the rates of 67.1% and 59.8% in SEER database. Conclusions: The malignant salivary gland tumor of the larynx is rare and it is difficult to be diagnosed early. It is more likely to occour local recurrence and distant metastasis. Extensive surgical resection with postoperative radiotherapy is advocated. PMID- 30293263 TI - [A case of esophagus foreign body misdiagnosed as foreign body aspiration].

AB - Cholesteatoma is an abnormal formation of benign cystic lesions from the squamous epithelium of the temporal bone, and the local invasive growth could damage the structures of middle ear. Cholesteatoma has been the research focus in otorhinolaryngology, however the pathogenesis of it is still unclear. From the previous studies we found that the epidermal proliferation was one of the important factors in the pathogenesis of the cholesteatoma, which was also involved in multiple proliferation pathways. In this paper, we briefly reviewed the progress and the mechanisms of the actions of cholesteatoma in these pathways.

The clinical symptoms and presentations base on degree of clefts and variety of comorbidities. Mild types of clefts may have minimal clinical impact, whereas severe types may be life-threatening and even lead to death before diagnosis. With more attention of these anomalies and advances in endoscopy, the diagnosis, evaluation and surgery of laryngeal clefts have acquired great improvement, especially International Pediatric Otolaryngology Group(IPOG)have reported consensus guidelines on the diagnosis and management of type I laryngeal clefts in 2017. This review of laryngeal clefts may be beneficial to decrease missed diagnosis or misdiagnosis and to achieve individual based treatment.

AB - In recent years, the incidence of thyroid carcinoma gradually increased in China. The pathology diagnosis and classification was based on WHO classification of Tumors of Endocrine Organs, the third edition which published in 2004. The fourth edition, WHO classification of Tumors of Endocrine Organs was published in July 2017. Compared with the third, some important aspects (or points) were revised: the ICD-O code of hyalinizing trabecular tumor was changed from 0 to 1; three other encapsulated follicular-patterned thyroid tumors were added; the variants of well differentiation thyroid carcinoma (including papillary carcinoma and follicular carcinoma ) which was originated from thyroid epithelial cells were updated; oncocytic cell tumors were separated from follicular tumors; the ICD-O code of ectopic thymoma was changed from 1 to 3. Refinement and standardization part of the concepts and diagnostic criterias were done which can solve practical problems in pathology diagnosis.

AB - Objective: To investigate the efficacy and the prognostic factors of Chinese Academy of Medical Sciences 2005 (CAMS-2005) regimen in the treatment of pediatric acute myeloid leukemia (AML). Methods: Eighty-eight cases of newly diagnosed AML patients, who were treated with the CAMS-2005 regimen from April 2005 to July 2009, were enrolled in this case observational study. Clinical characteristics, long-term prognosis and prognostic factors were analyzed retrospectively. Overall survival (OS) and event free survival (EFS) rates were estimated by the Kaplan-Meier method. Rates of survival between the groups were compared by the Log-rank test. Prognostic factors were evaluated by COX regression analysis. Results: A total of 82 cases were enrolled in this study, including 34 core binding factor(CBF)-AML patients and 48 non-CBF-AML patients. There were 45 males and 37 females. The median age at diagnosis was 8.0 (0.7 16.0) years. During the induction therapy, 3 patients (4%) developed treatment related early-death, while 63 patients (77%) achieved complete remission (CR) and 53 patients (65%) achieved CR after 1 course. Twenty-one patients (33%) had relapsed disease. The CR rates of CBF-AML patients and non-CBF-AML patients were 91% (31/34) and 67% (32/48) (chi(2)=5.410, P=0.020) , while the relapse rates were 29% (9/31) and 38% (12/32) (chi(2)=0.508, P=0.476) . The 8-year OS and EFS rates of all 82 patients were 59%(48/82) and 51%(42/82). The 8-year OS rates of CBF-AML patients and non-CBF-AML patients were 74% (25/34) and 48%(23/48) (chi(2)=5.812, P=0.016), while the 8-year EFS rates of CBF-AML patients and non CBF-AML patients were 71%(24/34) and 38%(18/48) (chi(2)=8.682, P=0.003). There were statistically significant differences between groups. The 8-year OS rates of patients who achieved CR after 1 course and other patients were 68% (36/53) and 46% (12/26) (chi(2)=9.606, P=0.002), while the 8-year EFS rates were 66% (35/53) and 27% (7/26) (chi(2)=19.471, P=0.000), the differences were all statistically significant. COX multivariate analysis showed that CBF-AML or non-CBF-AML and whether achieved CR after 1 course were independent prognostic factors of OS rates (relative risk: 2.538, 2.561) and EFS rates (relative risk: 3.050, 3.686) (P <0.05). Conclusions: The efficacy of the CAMS-2005 regimen in the treatment of AML patients was well. CBF-AML or non-CBF-AML and whether achieved CR after 1 course were independent prognostic factors for pediatric AML patients. PMID- 30293276 TI - [Expression and significance of programmed cell death ligand-1 in neuroblastoma tissues]. AB - Objective: To investigate the relationship between expression of programmed cell death ligand-1(PD-L1) in the tissue of neuroblastoma (NB) and patient's clinical characteristics and prognosis. Methods: Clinical data and surgical tissue paraffin blocks of 100 newly diagnosed NB children at Sun Yat-sen University Cancer Center between January 2000 and December 2015 were collected and the expression level of PD-L1 and its' relationship with pathological parameters and survival rate were analyzed retrospectively. The ratio between groups was compared by chi-square test. Kaplan-Meier method was used for survival analysis and COX regression model was used for multivariate analysis. Results: Among 100 cases, 71 were males and 29 females; there were 5 cases of stageI, 4 cases of stageII, 19 cases of stage III, 65 cases of stage IV and 7 cases of stage IVs. Ten out of 62 cases (16%) were N-MYC amplified; 15 cases were in low-risk group, 18 were in medium-risk group and 67 were in high-risk group. The positive rate of PD-L1 in NB tumor tissue was 57% (57/100), of which 55 were weakly positive, 1 was moderately positive and 1 was strongly positive. The positive rates of PD-L1 expression in tumor tissues without bone metastasis were higher than those with bone metastasis(66%(39/59)vs.44%(18/41), chi(2)=4.864, P=0.027), the positive rates of PD-L1 expression in tumor tissues pathologically diagnosed as neuroblastoma were higher than those pathologically diagnosed as ganglioneuroblastoma (61%(53/87) vs.31%(4/13), chi(2)=4.195, P=0.041), the positive rates of PD-L1 expression in tumor tissues originated from abdominal cavity were higher than those originated from other places (61% (51/83)vs.35%(6/17), chi(2)=3.937,P=0.047).The 4-year event-free survival (EFS) rates of patients with PD-L1 negative and positive were 40% and 33% (chi(2)=0.009, P=0.923), respectively. The 4-year overall survival (OS) rates of patients with PD-L1 negative and positive were 62% and 58% (chi(2)=0.294, P=0.587). Among 33 non-high-risk patients, the 4-year EFS rates of patients with PD-L1 negative and positive were 89% and 78% (chi(2)=0.001, P=0.965), the 4-year OS rates of patients with PD-L1 negative and positive were 100% and 96% (chi(2)=0.500, P=0.480). Among 67 high-risk patients, the 4-year EFS rates of patients with PD-L1 negative and positive were 24% and 11% (chi(2)=1.154, P=0.282), the 4-year OS rates of patients with PD-L1 negative and positive were 48% and 41% (chi(2)=0.692, P=0.405). Multivariate analysis showed that N-MYC gene amplification was an independent adverse prognostic factor for OS and EFS rates of NB patients (RR: 1.726,95%CI:1.209-2.466; RR:1.326,95%CI:1.014-1.736) and advanced clinical stage was an independent adverse prognostic factor for EFS rates of NB patients (RR: 26.498, 95%CI:3.518-199.614). Conclusions: The expression of PD-L1 in NB tumor tissues was correlated with the clinical characteristics of children. However, there were no significant differences in the prognosis of patients with or without PD-L1 expression. PMID- 30293277 TI - [Analysis of the arthropathies on no-bleeding history joints in pre-school age severe hemophilia A children]. AB - Objective: To detect the arthropathies on no bleeding history joints in pre school hemophilia A children in order to provide evidence for further prevention and control of joint disease in children with hemophilia A. Methods: This study was a cross-sectional study based on China Hemophilia Individualized prophylaxis study (CHIPS). The basic data of outpatients with hemophilia in Beijing Children's Hospital and Chengdu Women's and Children's Central Hospital between August 2016 and June 2017 were collected and a three-month follow-up was conducted. The target joints (six joints of bilateral elbows, knees and ankles) of thirty-four children aged 1-7 years old with severe hemophilia A were examined by ultrasound, X-ray and joint function examination (4-7 years old, hemophilia joint health score (HJHS)). To find out whether there are arthropathies in patient's joints with no bleeding history and analyze the relevant factors by chi square test, rank sum test and other statistical methods. Results: There were 32 analyzable cases with 112 no-bleeding history target joints, 42.9% (48/112) were elbow joints. Arthropathies were revealed in 34.8% (39/112) of them by joint structural and functional examination and 46.2% (18/39) were ankles (chi(2)=8.379, P=0.015) . Ultrasound showed abnormalities in 18.3% (20/109) joints, X-ray showed abnormalities in 3.8% (3/79) joints and HJHS showed abnormalities in 25.3% (20/79) joints. There was no correlation between ultrasound and HJHS (r=0.015, P=0.895), no correlation was found between X-ray and HJHS (r=-0.101, P=0.390) either, which suggested that joint structural and functional examination could not replace each other. The related risk factors of arthropathies in this group were >4.91 years old (OR=3.917, 95%CI:1.610-9.528) and combining with target joint (OR=3.530, 95%CI:1.316-9.465). Conclusions: Detecting the joint structure and function on no bleeding history joints in pre school hemophilia A children could reveal the arthropathies and majority of them were ankle arthropathies. Joint structural and functional examinations could not replace each other. For patients more than 5 years old and those with target joints, the joints with no complaint of bleeding should be examined regularly to reveal the arthropathies in time. PMID- 30293278 TI - [A national epidemiological survey on obesity of children under seven years of age in nine cities of China in 2016]. AB - Objective: To investigate the prevalence and risk factors of obesity in 2016 and to determine secular trend of the prevalence between 1986 and 2016 among Chinese children under seven years of age. Methods: Data of a total of 110 485 children from 1 month to 7 years of age were collected by stratified-clustered-random sampling method in the nine cities (including northern China (Beijing, Harbin, Xi'an), Central (Shanghai, Nanjing, Wuhan), Southern (Guangzhou, Fuzhou, Kunming)) from June to November in 2016. Overweight and obesity were defined by the weight for height of the American National Center for Health Statistics/World Health Organization (NCHS/WHO) reference and be over 10% as overweight and over 20% as obesity (20%-29% as mild, 30%-49% as moderate and over 50% as severe). The normal children were matched with obese children in sex, age and height in the case-control designs and the data were analyzed by chi(2) test and conditional Logistic regression model. Results: (1) The overall overweight prevalence was 8.4% (9 317/110 485) with boys 8.4% (4 843/57 917) and girls 8.5% (4 474/52 568) and the overall obesity prevalence was 4.2% (4 712/110 485) with boys 4.9% (2 860/57 917) and girls 3.6% (1 852/52 568). The obesity prevalence was significantly different across age groups (chi(2)=3 777.586, P<0.01), the lowest 0.9% (144/16 380) (boys 1.1% (97/8 668), girls 0.6% (47/7 712)) at 1-<2 year and the highest 11.3% (1 248/11 072) (boys 14.0% (822/5 861), girls 8.2% (426/5 211)) at 6-<7 years. The overall obesity prevalence was 4.6% (2 534/54 970) for suburban rural children and 4.0% (2 178/55 515) for urban children. The overall obesity prevalence in northern, central and southern China was 4.7% (1 985/42 294), 4.4% (1 543/35 260) and 3.6% (1 184/32 931) respectively. The mild obesity prevalence was 2.8% (3 146/110 485) and the moderate 1.1% (1 272/110 485) and severe obesity 0.3% (294/110 485). (2) To ensure data comparability, the 2016 urban data were compared with the previous survey urban data. Compared with the 1986 and 2006 survey data, the obesity prevalence increased from 0.9% (660/71 420) and 3.8%(2 227/59 302) to 4.6% (1 341/29 054) for boys, from 0.9% (596/66 609) and 2.5%(1 323/53 643) to 3.1% (837/26 461) for girls. The increase in prevalence of obesity mainly appeared after 3 years of age. The obesity prevalence among north, central and south China increased from 1.8% (562/31 301) and 3.2% (1 137/35 439) to 4.2% (864/20 372), from 0.9% (464/52 138) and 3.9%(1 412/37 031) to 4.2% (764/18 485), from 0.4% (230/54 590) and 2.5% (1 001/40 475) to 3.4% (550/16 658) when compared with 1986 and 2006. (3) Multivariate Logistic regression analysis showed that high birth weight (odds ratio (OR)=1.559 (1.038 2.343), chi(2)=4.580, P<0.05), cesarean section (OR=1.651 (1.230-2.216), chi(2)=11.132, P<0.01), gestational diabetes (OR=3.364 (1.406-8.047), chi(2)=7.433, P<0.01), father overweight (OR=1.935 (1.417-2.642), chi(2)=17.267, P<0.01) or father obesity (OR=3.580 (2.304-5.561), chi(2)=32.196, P<0.01), mother overweight (OR=2.305 (1.611-3.298), chi(2)=20.854, P<0.01) or mother obesity (OR=5.232 (2.751-9.949), chi(2)=25.462, P<0.01), good appetite (OR=8.313 (5.385 12.833), chi(2)=91.403, P<0.01), eating fast (OR=6.359 (4.539-9.010), chi(2)=112.513, P<0.01), eating shortly before sleeping (OR=1.553 (1.113-2.166), chi(2)=6.707, P<0.01), long screen watching duration (2-<3 hours: OR=1.973 (1.423 2.736), chi(2)=16.594, P<0.01 or >=3 hours: OR=2.275 (1.413-3.661), chi(2)=11.448, P<0.01), short night sleep duration (8-<9 h/day) (OR=1.600 (1.074 2.385), chi(2)=5.331, P<0.05), low education of mother (OR=1.589 (1.298-1.945), chi(2)=20.174, P<0.01) may be risk factors for children's obesity; moderate and excessive outdoor activities (e.g. running, jumping) may be protective factors against obesity (OR=0.540 (0.342-0.853), chi(2)=6.990, P<0.01). Conclusions: In recent ten years the rapidly increasing trend of children obesity has not been effectively curbed and there has been a new situation in the obesity prevalence of suburban rural children exceeding urban children. The key roles of mother in the early growth and development and family in the formation of good behavior habits of their children should be paid attention to, and family-based obesity prevention and control strategies for preschool children should be developed and improved to correct unhealthy family sharing environment and children's lifestyle. PMID- 30293279 TI - [Interleukin-10 receptor gene mutations induced very early onset inflammatory bowel disease in 6 infants]. AB - Objective: To analyze the clinical features and interleukin-10 receptor gene mutations in six infants with very early onset inflammatory bowel disease (VEO IBD). Methods: Four girls and two boys with VEO-IBD admitted to Children's Hospital Affiliated to Capital Institute of Pediatrics from June 2016 to September 2017 were reviewed. The clinical data including general condition, clinical symptoms, laboratory tests, and colonoscopy and pathological results were collected and analyzed. Interleukin-10 receptor alpha subunit (IL-10RA) gene was examined in all patients. Results: Persistent diarrhea and fever were the most common symptoms and were found within 1 month after birth in all 6 patients. Anemia, oral ulcer or perianal lesions and growth retardation were common concomitant symptoms. All patients had colonoscopy examination and the results showed multiple ulcers affecting the colon with biopsies revealing acute and chronic inflammation. Three patients were found to have cryptitis and crypt abscesses. Gene sequencing revealed IL-10RA gene mutations in all six patients, including 3 cases with homozygous mutations (one with c.537G>A and two with c.301C>T) and 3 heterozygous mutations (paternal c.301C>T in all cases; maternal c.299T>G, c.350G>A and c.537G>A, respectively) . After conventional treatment, one got clinical and pathological improvement according to colonoscopy, three improved clinically, one worsened and died, and one died of septic shock secondary to intestinal perforation. Conclusions: VEO-IBD is associated with IL 10RA mutation, usually with severe intestinal symptoms and significant extra intestinal symptoms, as well as varied responses to conventional treatment. In our study, c.301C>T and c.537G>A are the most common mutations. PMID- 30293280 TI - [Clinical and pathological features of 13 children with Epstein-Barr virus positive lymphoproliferative disease]. AB - Objective: To summarize the clinical characteristics, virological and histopathological features, clinical outcome of Epstein-Barr virus-positive lymphoproliferative disease (EBV(+)LPD) in children. Methods: The clinical and follow-up data of 13 children histopathologically diagnosed as EBV(+)LPD in the Department of Infectious Disease of Beijing Children's Hospital between January 2011 and December 2016 were summarized. Results: Of the 13 patients, 5 were males and 8 females. The median age of disease onset was 6.0 years (range 1.3 to 15.0 years). The median duration between disease onset and diagnosis was 3 months (range 1 to 24 months). All the 13 patients had fever, 9 cases had hepatosplenomegaly and lymphoadenopathy, 4 cases had only lymphoadenopathy, 7 cases had reduced peripheral blood cells, 7 cases had lung involvement, 3 cases had central nervous system involvement, 3 cases had cardiac involvement, 3 cases had intestinal involvement, 2 cases had skin involvement and 1 case had abdominal mass. All the 13 patients underwent whole blood EBV-DNA PCR examination and the copies ranged from 1*10(8)/L to 1*10(11)/L. Pathology of lymph node confirmed 6 cases, skin pathology confirmed 2 cases, lung pathology, ileum mucosa pathology, liver pathology, abdominal mass pathology and bone marrow pathology confirmed 1 case each. Among 13 patients, 9 cases presented with EBV-positive T cell lymphoproliferative disease(EBV(+) T-LPD), 2 cases with hydroa vacciniforme (HV) and 2 cases with EBV-positive diffuse large B-cell lymphoma (EBV(+) DLBCL) . All the patients were followed up for 2 days to 65 months after discharge. Among 9 cases of EBV(+)T-LPD, 1 case died in a short time, 1 case died after evolved to T cell lymphoma, 2 cases recovered after hematopoietic stem cell transplantation, 1 case recovered after the chemotherapy of hemophagocytic lymphohistiocytosis(HLH) 2004 protocol and 4 cases were stable now. Of 2 cases of HV patients, 1 case died after evolved to HV like lymphoma and the other still have symptoms. Among 2 cases of EBV(+) DLBCL, 1 case died shortly after discharge and the other was still stable after chemotherapy. Conclusions: Chronic recurrent fever, lymphadenopathy and hepatosplenomegaly are the most common clinical manifestations in children with EBV(+)LPD. Involvement of lung, central nervous system, intestinal tract, skin and other organs are also involved frequently. For children with chronic fever of unknown cause and accompanied by lymphadenopathy and (or) hepatosplenomegaly, EBV (+) LPD should be considered highly when the whole blood EBV-DNA load continues to increase significantly, early biopsy of the proliferative lesion should be performed to make a definite diagnosis. The prognosis of EBV (+) LPD is poor, and some evolve to lymphoma, hematopoietic stem cell transplantation is an effective way to treat this disease. PMID- 30293281 TI - [Diagnosis and treatment of five neonatal cerebral venous sinus thrombosis]. AB - Objective: To summarize the clinical presentations and imaging features of cerebral venous sinus thrombosis (CVST) in 5 newborns. Methods: The clinical data of 5 newborns with CVST admitted to Department of Neonatology of Maternal and Children Hospital of Hubei Province from February 2017 to April 2018 were analyzed retrospectively. The risk factors, clinical presentations, imaging manifestations and treatment of CVST were investigated. Results: Of the 5 full term neonates, 4 were males and 1 female, with 4 aged less than 7 days and 1 more than 7 days; one with the history of maternal gestational diabetes mellitus, one with maternal gestational hypertension. The clinical presentations included seizures (3 cases), fever (3 cases), dehydration (1 cases), lethargy (2 cases), hypoglycemia (2 cases), thrombocytopenia (2 cases). Electroencephalogram (EEG) showed electrical seizures in 3 cases. Magnetic resonance imaging (MRI) and magnetic resonance venography (MRV) showed 4 cases of intracranial hemorrhage, 3 cases of cerebral parenchymal infarction. For the sites of the thrombi, 4 were in the superior sagittal sinus, 3 in straight sinus, 2 in transverse sinus and 1 in sinus confluence. CT showed intracranial hemorrhage in 2 cases and venous sinus dilatation in 2 cases. Doppler ultrasound showed 2 cases of intraventricular hemorrhage and 2 cases of changes of venous sinus blood flow. Three neonates were treated with anticoagulant and thrombolytic therapy, followed by recanalization of the veins and discontinuing of seizures. Conclusions: Seizure is the main clinical presentation of CVST. The main radiologic manifestations are cerebral infarction and hemorrhage. Timely brain MRI and MRV are helpful in the early diagnosis and treatment of CVST. PMID- 30293282 TI - [Clinical and pathological features and mutational types of WT1 mutation associated nephropathy]. AB - Objective: To explore the clinical and pathological features and mutational types and their relations with WT1 mutation-associated nephropathy (WT1MAN). Methods: The clinical and pathological data and the results of WT1 mutation analysis of the cases from Nanfang Hospital of Southern Medical University, Sun Yat-sen Memorial Hospital and The First Affiliated Hospital of Sun Yat-sen University whom we recruited recently and reported during the last ten years were analyzed. Results: Totally, 20 cases (6 males and 14 females), included 5 newly diagnosed cases, were recruited. (1) Ten children were diagnosed with Denys-Drash syndrome (DDS): The median onset age of proteinuria was 1 year and 7 months. Diffuse mesangial sclerosis (DMS) were revealed in 3 cases, minimal lesions (MCD) in 4 cases, and focal segmental glomerulosclerosis (FSGS) in 1 case; renal pathology was not available in the other 2 cases. Glomerular basement membrane (GBM) thickening was observed in 2 cases. Calcineurin inhibitors (CNIs) were administered in 5 cases, complete remission of proteinuria was observed in 3 cases, partial remission in the other 2 cases. Genetic analysis revealed that six cases had WT1 missense mutation, 3 had nonsense mutation, and 1 had frameshift mutation. (2) Two cases were diagnosed with Frasier syndrome (FS): proteinuria was observed at 1 year and 1 month of age and 1 year and 9 months of age, respectively. FSGS with GBM layering were observed in both cases. They progressed to ESRD at 1 year and 6 months of age and 6 years and 6 months of age, respectively. CNI was tried in 1 case with partial proteinuria remission. Both patients were detected to have WT1 splice mutation. (3) Isolated nephropathy (IN) was observed in 8 cases: three had splice mutation, 5 had missense mutation. Of the 3 patients with splice mutation, one was found to have nephropathy and renal failure at the age of 5 months. The other two cases (1 was FSGS and another MCD), both had GBM layering. CNIs were tried on both of them, one got partial remission with normal renal function at the age of fourteen years, the other one had no response and entered ESRD at the age of 6 years and 9 months. Of the 5 cases with missense mutation, 3 had DMS, 2 of them entered ESRD within 6 months of age, another case had DMS entered ESRD at 9 years of age. One case with FSGS, was treated with CNIs and got complete remission. Conclusions: Slow progression (7/10) nephropathy was observed in DDS patients. Missense mutation (11/20) was the most common type of WT1 variants, followed by splice mutation (5/20) in this group of patients. Early onset nephropathy (4/5), rapid progression (4/5) and GBM layering (4/4) wereobserved in patients with splice mutation. CNI was effective in reducing or even eliminating proteinuria in WT1 MAN patients (8/9). PMID- 30293283 TI - [No.145: fever, cough for 9 days, weakness, shortness of breath for 3 days].

AB - Objective: To evaluate the safety and perinatal outcomes of thoracoamniotic shunting in the treatment of fetuses with severe primary hydrothorax. Methods: 22 cases of suspected severe primary fetal hydrothorax which underwent thoraco amniotic shunting in Shanghai First Maternity and Infant Hospital, Fetal Medicine Unit and Prenatal Diagnosis Center from January 2012 to December 2017 were analyzed retrospectively. Hydrothorax associated with structural or chromosomal abnormalities, infections and immune fetal hydrops were excluded. Results: Totally, 28 shunts were placed in 22 fetuses. The median gestational age at TAS was 31.3 weeks. Preterm membrane rupture within 7 days after the procedure occurred in 9.1% (2/22) cases. Catheter displacement occurred in 18% (4/22) cases. The interval from shunting to delivery was 26.0 days. One fetus ended in induced abortion; 21 (95%, 21/22) babies were born alive, and their median gestational age at delivery was 34.4 weeks. 62% (13/21) newborns required ventilator supports; 4 neonatal deaths were attributed to pulmonary hypoplasia. The overall perinatal survival rate was 81% (17/21) . The perinatal survival rate with hydrops and without hydrops were 10/13 and 7/8 respectively. Conclusion: Thoraco-amniotic shunting is a safe procedure for intrauterine therapy and could improve the perinatal outcomes of severe primary fetal hydrothorax.

AB - Objective: To investigate the relationship between thyrotropin (TSH) and urine iodine in pregnant women of Han and Uygur ethnic groups in People's Hospital of Xinjiang Uygur Autonomous Region. Methods: A total of 1 568 pregnant who completed screening of TSH and urine iodine in People's Hospital of Xinjiang Uygur Autonomous Region hospital from August 2014 to December 2017 were included in the study, 956 cases were Han and the other 612 were Uygur. Basic clinical data, serum TSH, thyroid peroxidase autoantibody (TPOAb) , and urine iodine levels were retrospectively analyzed. Results: (1) General results: The median urine iodine level was 162.6 MUg/L (53.4-539.3 MUg/L) , and the distribution of urine iodine classification was iodine deficiency 42.9% (672/1 568) , iodine appropriate 36.7% (576/1 568) , iodine slightly high 17.1% (268/1 568) and iodine excess 3.3% (52/1 568) respectively. (2) The median urine iodine levels of Han and Uygur pregnant women were 169.1 MUg/L (54.6-583.4 MUg/L) and 156.3 MUg/L (53.1-539.3 MUg/L) respectively, and the difference was statistically significant (P<0.05) .The distribution of urine iodine status in pregnancy between Han and Uygur was significantly different, which were 40.9% (391/956) vs. 45.9% (281/612) in iodine deficiency, 35.4% (338/956) vs. 38.9% (238/612) in iodine appropriate, 20.2% (193/956) vs. 12.3% (75/612) in iodine slightly high and 3.6% (34/956) vs. 2.9% (18/612) in iodine excess. (3) High serum TSH level proportion was significantly higher in Uygur ethnic group, early pregnancy, thyroid peroxidase antibody positive and anti-thyroglobulin antibody positive group when compared with Han, late pregnancy, thyroid peroxidase antibody negative and anti thyroglobulin antibody negative groups (all P<0.05) . There were no significant differences in different age groups and iodine nutrition groups (P>0.05) . (4) There was no correlation between urinary iodine and TSH levels in all pregnant women (P>0.05) , neither in Han or Uygur group. When further stratified by gestational age, age, and antibody level, there was a positive correlation between urine iodine and serum TSH level in Han pregnant women >30 years old (P<0.05) , and there was a negative correlation in the third trimester in Uygur (P<0.05) . When serum antibody level, gestational week and age were controlled. There was no correlation between urine iodine and serum TSH level in neither group. Conclusions: (1) In Han and Uygur pregnant women, the median urine iodine level and the distribution of urine iodine classification between two ethnic groups are significantly different. (2) The correlation between urine iodine and serum TSH is not identified in Han or Uygur pregnant women.

PMID- 30293296 TI - [Method selection and perioperative management of termination of pregnancy during the first and second trimester of pregnancy with severe cardiovascular disease]. AB - Objective: To summarize and analyze the methods of termination of pregnancy in the first and second trimester of pregnancy with severe cardiovascular disease. Methods: A retrospective analysis of 27 cases of termination of pregnancy in the first and second trimester of pregnancy in Beijing Anzhen Hospital from January 1, 2016 to December 30, 2017. All of these pregnant women were pregnancy complicated with severe cardiovascular disease in grade V pregnancy risk. Results: (1) The age of 27 pregnant women was 22-40 years, gestational age was 6 27 weeks; cardiac function grade before induced labor was: 5 cases of grade II, 15 cases of grade III, 7 cases of grade IV. The cardiovascular diseases included ventricular septal defect in 9 cases, simple atrial septal defect in 3 cases, patent ductus arteriosus in 2 cases, tetralogy of Fallot in 2 cases, rheumatic valvular disease in 1 case,arrhythmia-paroxysmal atrial velocity in 2 cases, cardiomyopathy in 2 cases, hypertensive cardiopathy in 2 cases, primary pulmonary hypertension in 1 case, tissue disease complicated with pulmonary hypertension 1 case, hyperthyroid heart disease in 1 case, coronary heart disease in 1 case. Among them, 21 cases were complicated with pulmonary hypertension, and 5 cases with Eisenmenger syndrome. (2) Methods of termination of pregnancy: in 27 cases, eight cases of vacuum curettage, and 2 cases of forceps curettage under general anesthesia without intubation; rivanol intraamniotic induction of labor in 1 case; and hysterotomy delivery in 16 cases (11 cases were treated with continuous epidural anesthesia, 1 case was treated with combined spinal and epidural anesthesia, 4 cases were treated with spinal anesthesia) . (3) After termination of pregnancy, one patient with severe primary pulmonary hypertension at 19 weeks of gestation died on the 1st day postoperative. No significant changes in cardiac function were observed in other patients before and after termination of pregnancy, and all of them survived. Conclusions: In patients with severe cardiovascular disease, termination of pregnancy after pregnancy may result in maternal death even at the second trimester of pregnancy.It is strongly recommended that such patients undergo pre-pregnancy assessment and fertility counseling.If visiting doctor after pregnancy, we should organize a multidisciplinary consultation as soon as possible to assess the risk of continuing pregnancy and give medical advice. If the risk of pregnancy is high, we should terminate the pregnancy as early as possible, after making a suitable treatment plan. During termination of pregnancy, temporary or permanent contraception may be taken if the condition permits. PMID- 30293297 TI - [Analysis of the missed diagnosis of invasive carcinoma under the microscope in HSIL diagnosed by colposcopy-guided biopsy and related influencing factors]. AB - Objective: To observe the missed diagnosis of invasive carcinoma under the microscope (ICUM) in high grade squamous intraepithelial neoplasia (HSIL) , and analyze associated factors influencing missed ICUM. Methods: A retrospective study was performed on patients diagnosed with HSIL by colposcopy-guided biopsy and treated with loop electrosurgical excision procedure (LEEP) at the First Affiliated Hospital of Nanjing Medical University, from December 2014 to December 2016. They were non-pregnant, <=50 years old and the cervical volume without obvious enlargement and exogenous surface without and ulcerative lesions. A total of 283 cases with early cervical cytology results, never received cervical traumatic treatment or cervical biopsy in another hospital before, and their colposcopic images were clear enough to reevaluate. The ultimate pathological diagnosis was based on the higher-level pathological diagnosis between the results of cervical biopsy and LEEP to evaluate ICUM missed in HSIL and the risk factors. Results: (1) Among the 283 cases with HSIL diagnosed by colposcopy directed biopsy, 44 cases (15.5%, 44/283) were missed diagnosis of ICUM, which consisted of 29 cases I a1, 4 cases I a2 and 11 cases I b1 in the ultimate pathology. (2) Analysis of associated factors for missed ICUM: univariate analysis showed that, as the age increased, the risk of missed ICUM also increased (the rates of missed diagnosis for <30, 30-39, 40-50 years were 7.7%, 11.5%, 22.0%, respectively; chi(2)=6.254, P=0.012 by trend test) . The more the number of high-grade features, the higher risks (the rates of missed diagnosis for 1, 2, 3, 4 high-grade features were 10.2%, 17.6%, 23.8%, 30.8%, respectively; chi(2)=7.686, P=0.006 by trend test) . The locations of HSIL were only endocervical, only ectocervical and mixed, the risk increased by this sequence (2.8%, 5.1%, 28.7%; chi(2)=26.193, P<0.01 by trend test) . The rate of missed diagnosis for not completely visible squamocolumnar junction (SCJ) was higher than that of the completely visible one (22.3% vs 2.1%; chi(2)=19.680, P<0.01) . The rate of missed diagnosis was higher for existing atypical vessels than those without (60.7% vs 10.6%; chi(2)=48.279, P<0.01) . The rate of missed diagnosis for visible lesion size >=40 mm(2) was higher than that of <40 mm(2) (27.3% vs 4.2%; chi(2)=28.921, P<0.01) . The rate of missed diagnosis for the proportion of visible lesion size in ectocervical size >=0.75 was higher than that of <0.75 (83.3% vs 14.1%; P<0.01) . The rate of missed diagnosis for the maximum linear length of visible lesion >=10 mm was higher than that of <10 mm (46.9% vs 9.0%; chi(2)=44.473, P<0.01) . But the different severity of cervical cytology before colposcopy was not associated with missed ICUM (P>0.05) . Multivariable analysis found that visibility of SCJ, atypical vessels, visible lesion size and maximum linear length of visible lesion were associated with missed diagnosis of ICUM (all P<0.05) . Conclusions: The diagnostic value of HSIL by colposcopy is limited. Meanwhile, for the patients who are <=50 years old with HSIL diagnosed by cervical biopsy, invisibility of SCJ, atypical vessels, visible lesion size and maximum linear length of visible lesion evaluated by colposcopy are the independent risk factors of missed ICUM. Thereby, it is necessary to take active intervention for HSIL with these risk factors. PMID- 30293298 TI - [Clinical management of 110 cases of polypropylene mesh and sling exposure after reconstructive pelvic floor surgery]. AB - Objective: To explore the clinical management and outcomes of polypropylene mesh and sling exposure after reconstructive pelvic surgery (RPS) . Methods: A total of 110 cases of mesh and sling exposure after RPS were analyzed, who admitted between Jan. 2002 and Oct. 2017 in First Affiliated Hospital of PLA General Hospital, in which 3 cases were referred from other hospitals. Mesh and sling exposures were identified in the outpatient clinic and categorized and managed according to International Continence Society and International Urogynecology Association (ICS-IUGA) classification about category, time and site (CTS) of mesh complication. Outpatient management included observation, topical estrogen use and mesh removal. Management in hospital included surgical removal of exposed mesh and repair of the resulting defects under the anesthesia. Seventy-four cases were managed in the outpatient setting, and 36 cases required inpatient management. Follow-up was consecutively performed from 1 month to 10 years. Objective outcome included the surgeon's assessment of the healing state of the vaginal mucosa. Subjective outcome was evaluated with patient global impression of improvement questionnaire (PGI-I) . Results: One hundred and ten patients with mesh exposure were classified according to the different RPS underwent. There were 95 cases from transvaginal mesh surgery, 5 cases from anti-stress urinary incontinence sling surgery, and 10 cases from sacrocolpopxy. The outpatient group healed at an average of (3.0+/-1.8) months. Of the 36 patients who required inpatient management, 21 cases healed completely at an average of 7 days after one surgery. The remaining 8 cases required either two or three times surgeries or conservative management. In the outpatient group, the PGI-I scale very much better was found in 65 cases (87.8%) and much better in 9 cases (12.2%) . In the inpatient surgery group, the scale was very much better in 30 cases (83.3%) , and much better in 6 cases (16.7%) . Conclusions: Among patients with mesh exposure after mesh-augmented RPS, 2/3 of patients with a CTS classification 1-3 could be managed in the office, and remaining 1/3 with CTS classification 4-6 need operation under anesthesia in hospital. If the mesh and sling exposure could be scientifically classified, according to the size, site and accompany symptoms, as well as pain, most of the mesh complications after explosure could be resolved. Using the pelvic floor repair and polypropylene mesh sling, the majority of the patients could get a better outcome, without affecting the effect of the original operation.

PMID- 30293301 TI - [Epidemiological features of hepatitis C and its related influencing factors in Shandong province, 2007-2016]. AB - Objective: To analyze the epidemiological characteristics, dynamic trend of development and related influencing factors of hepatitis C in Shandong, China, 2007-2016, also to provide epidemiological evidence for prevention and control of HCV. Methods: National surveillance data of hepatitis C from 2007 to 2016 in Shandong was used, with distribution and clustering map of hepatitis C drawn at the county level. Panel Poisson regression was used to explore the influencing factors of hepatitis C at the city level. Results: The incidence of hepatitis C in Shandong increased from 1.49/100 000 in 2007 to 4.72/100 000 in 2016, with the high incidence mainly clustered in the urban regions in Jinan, Zibo, Weihai et al. and surrounding vicinities. Majority of the cases were young adults, with 53.16% (14 711/27 671) of them being farmers. Results from the Multiple panel Poisson regression analysis indicated that factors as: population density (aIRR=1.07, 95%CI: 1.05-1.10), number of hospital per hundred thousand people shared (aIRR=1.16, 95%CI: 1.08-1.24), expenditure of medical fee in rural (aIRR=1.21, 95%CI: 1.08-1.37) and the proportion of the tertiary industry (aIRR=1.08, 95%CI: 1.07-1.09) were all correlated to the incidence of hepatitis C. Conclusions: The incidence of hepatitis C had been increasing rapidly in recent years, in Shandong. Prevention and control of HCV should focus on high risk population. In addition, rural, especially in areas with lower economics provision should be under more attentions, so as to find more concealed cases for early treatment. PMID- 30293302 TI - [Analysis on the spatial-temporal characteristics of hand-foot-mouth disease in Shaanxi province, 2009-2013]. AB - Objective: To study the spatial-temporal dynamical features of hand-foot-mouth disease (HFMD) in Shaanxi Province, so as to provide evidence for the development of relative prevention and control programs on HFMD. Methods: Surveillance data of HFMD was collected from the China Information System for Diseases Control and Prevention from 2009 to 2013. Related data on population and gross domestic product (GDP) was obtained from Shaanxi Statistical Yearbook. Statistical tools as R3.4.1, ArcGIS 10.2 and SaTScan 9.2 software were used to describe the spatial temporal distribution of the disease. Power-law method on spatial-temporal multicomponent model was used to analyze the spatial-temporal evolution of the HFMD epidemics in Shaanxi Province. Results: A total of 229 904 cases of HFMD were reported in Shaanxi Province from 2009 to 2013, with an average annual incidence as 122.50 per 100 000. Obvious seasonal characteristics were noticed, with 71.71% of the total cases identified between April and July. Counties with high incidence were mainly distributed in the mid-and east parts of Guanzhong area. Through temporal and spatial scan statistics, we identified that ClassI clustering area was fixed to the central and southeast regions of Shaanxi province which were around Xi'an City between 2009 and 2013, with the relative risk (RR) as 2.24, ranging from 2.18 to 3.08. Results from Power-law analysis showed that the continuous follow-up impact from the previous HFMD epidemics appeared strong in Tongguan, Pucheng districts of Weinan City and Weiyang district of Xi'an, with autoregressive components as 1.14, 0.97 and 0.89, respectively. The risk of HFMD seemed high in Huayin city, Changan and Yanta districts and with the endemic components as 5.08, 4.12 and 4.08, respectively. Impact of the epidemics on nearby districts was largely seen in Lianhu district of Xi'an, Wugong district of Xianyang and Gaoling district of Xi'an with epidemic components as 2.12, 2.08 and 1.77, respectively. The etiological constituents of HFMD were mainly Enterovirus 71 between 2009 and 2012, while HFMD was mainly caused by other entero-viruses, in 2013. Conclusion: Significant spatial-temporal heterogeneity of HFMD was seen in Shaanxi province, which called for specific strategies to be developed in the highly endemic areas. PMID- 30293303 TI - [Epidemiological characteristics and environmental risk factors of hemorrhagic fever with renal syndrome in Wei River basin, China, 2005-2015]. AB - Objective: To understand the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in Wei River Basin from 2005 to 2015, and analyze the environmental factors that cause the differences of spatial distribution. Methods: HFRS reported cases in Wei River Basin from 2005 to 2015 were collected form "National Disease Reporting Information System" , and the epidemiological features of HFRS were analyzed. Boosted regression trees (BRT) model was applied to evaluate the environment factors on the geographical distribution of HFRS in Wei River basin at 5 km*5 km gird scale. Results: The number of HFRS cases was 18 629, and the average annual incidence from 2005-2015 in Wei River basin was 7.24/100 000. The highest morbidity was 15.18/100 000 in 2012. The middle and lower reaches of Wei River basin had high incidence of HFRS, such as Xi'an, Weinan city. Patients' age was mainly between 16 to 60, and the largest morbidity occured in people over 60 years old. Boosted regression trees modle identified building land, farmland coverage percentage and altitude had higher contribution to the distribution of HFRS. Conclusions: The epidemiological characteristics of HFRS changed significantly. Patients older than 60 years old were having the highest incidence rates. Environmental factors such as buildup land, farmland and altitude played important roles in the geographical distribution of HFRS in the Wei River basin. PMID- 30293304 TI - [Characteristics on spatial and temporal distribution as well as the driving effect of meteorological factors on brucellosis in Datong city, Shanxi province, 2005-2015]. AB - Objective: To explore the spatio-temporal epidemic trends and related driving effects of meteorological factors on brucellosis in Datong city, Shanxi province, from 2005 to 2015. Methods: We collected the surveillance data on brucellosis and related meteorological data in Datong city from 2005 to 2015, to describe the epidemic characteristics of the disease. Quasi-Poisson distribution lag non-liner model (DLNM) was built to explore the driving effect of monthly meteorological data on the disease. Results: From 2005 to 2015, Datong city reported a total of 17 311 cases of brucellosis including one death, with the annual average incidence as 47.43 per 100 000 persons. A rising trend was seen during the study period. The monthly incidence of Brucellosis presented an obvious curve with a major peak from March to June, accounted for 48.40% of the total cases. The high incidence areas in the city gradually expanded from the northeast and southeast to the western areas. Results from the DLNM studies suggested that seasonality of brucellosis in Datong was significantly affected by metrological factors such as evaporation, rainfall and temperature. The peak of delayed effect appeared the highest when the monthly cumulative evaporation capacity was 140-260 mm and the monthly cumulative rainfall was 20-60 mm with lag less than 1 month or the monthly temperature was -13 C with lag of 4-5 months. Conclusions: The incidence of human brucellosis in Datong city increased significantly from 2005 to 2015. Meteorological factors such as evaporation, rainfall, temperature all showed significant driving effects on the disease. PMID- 30293306 TI - [Epidemiologic survey on the prevalence and distribution of infants' common gastrointestinal symptoms in 7 cities in China: a population-based study]. AB - Objective: Regurgitation, infantile colic, and functional constipation are common gastrointestinal symptoms in childhood, the aim of this study was to explore the prevalence and distribution of these symptoms in China. Methods: A screening program in infants aged 0 to 3 years selected through stratified cluster random sampling was carried out in 7 cities in China. Questionnaires were filled, and then diagnosis were made according to Rome IV criteria. Areas, (urban-rural), age and gender distribution of prevalence of childhood common gastrointestinal symptoms were analyzed. Results: Totally, 20 932 effective questionnaires were returned. The total number of infants aged 0 to 1 years was 10 193. Regurgitation was diagnosed in 1 960 infants, with the prevalence of 19.2%, among infants aged 0 to 3 months that had highest prevalence (29.8%). The prevalence decreased with age, and differences among different age groups showed significant. For infantile colic, 4 470 infants aged 0 to 5 months were analyzed and the prevalence of infantile colic was 7.3%. The prevalence of infantile colic was the highest in infants aged 1 to 2 months (10.0%). Age specific difference was significant. Of all the infants, functional constipation was diagnosed in 1 755 infants with the prevalence of 8.4%, and the lowest prevalence was found in infants aged 0 to 3 months (6.2%), and the highest prevalence was in infants aged 30 to 36 months (10.0%). The differences in different age group were significant. Conclusion: Symptoms of regurgitation, infantile colic, and functional constipation are common in infants in China, with age specific difference in prevalence of the symptoms. PMID- 30293305 TI - [Association between central obesity and risk for heart disease in adults in China: a prospective study]. AB - Objective: To understand the association between central obesity, assessed by waist circumference, and the risks for ischemic heart disease (IHD), major coronary event (MCE), and IHD death. Methods: After excluding participants with heart disease, stroke, cancer, COPD, and diabetes at baseline survey, we included a total of 428 595 participants from the China Kadoorie Biobank for the analysis. The baseline survey was conducted from June 2004 to July 2008. We used Cox proportional hazards model to estimate the hazard ratio (HR) and 95%CI. Results: During an average 9.1 years of follow-up (3 803 637 person-years), we documented 26 900 incident cases of IHD, 4 320 cases of MCE, and 2 787 of deaths from IHD. After adjustment for possible confounders and BMI, central obesity was found to be associated with increased risks for IHD, MCE, and IHD death. The adjusted HRs (for the participants who had waist circumference of 85.0-89.9 cm in men and 80.0 84.9 cm in women were 1.13 (95%CI: 1.09-1.17) for IHD, 1.15 (95%CI: 1.05-1.26) for MCE and 1.11 (95%CI: 0.98-1.24) for IHD death. The respective HRs for those central obese participants (men >=90.0 cm, women >=85.0 cm) were 1.29 (95%CI: 1.24-1.34), 1.30 (95%CI: 1.17-1.44) and 1.32 (95%CI: 1.16-1.51). Further stratification analysis according to BMI showed that the risks for incident IHD, MCE, and IHD death increased along with the increase of waist circumference even in the participants with normal weight. Conclusion: This large-scale prospective study revealed that central obesity was an independent risk factor for IHD in adults in China, and the risk of IHD would increase with the increase of waist circumference.

Statistical analyses were conducted by using complex sampling analyses module of SPSS 20.0, with weights as a combination of sampling weights, non-response weights and post- stratification weights, for the calculation of current smoking prevalence, daily smoking prevalence, smoking cessation rate, etc. Results: A total of 8 484 and 9 372 valid questionnaires were obtained, respectively, in 2014 and 2016, with the response rate of 86.5% and 96.5%. The current smoking prevalence in persons aged 15 years and over was 23.4% in 2014, and 22.3% in 2016. According to the 6(th) national census data, the current smoking population decreased by 199 000 in Beijing. The proportion of daily smokers declined from 20.7% in 2014 to 19.2% in 2016. The daily number of cigarettes consumed by current smokers increased from 14.6 in 2014 to 15.4 in 2016. The smoking cessation rate was 14.9% in 2014 and 16.8% in 2016. The proportion of current smokers who had at least one smoking cessation attempt in the past 12 months increased from 22.3% in 2014 to 23.2% in 2016, and the proportion of current smokers who planned to quit smoking increased from 11.6% to 15.5%. Among the current smokers who had visited doctors in the past 12 months, the proportion of those having smoking cessation advice was 58.9% in 2014 and 59.2% in 2016. In 2016, among the current smokers who had attempted to quit in the past 12 months, 36.8% were aware of the smoking cessation clinics, and 29.5%were aware of the quitline. Among those who were aware, only 7.7% had actually visited the cessation clinics, and 5.5% had used the quitline. Conclusions: After the implementation of 2015 Beijing Tobacco Control Regulation for 1 year, the current smoking prevalence in persons aged 15 years and over showed decreasing. It is necessary to further prompt the expansion of smoking cessation service to cover more current smokers. PMID- 30293309 TI - [Subjective well-being feelings and related factors in people aged 50 years or older in Shanghai: Based on Day Reconstruction Method]. AB - Objective: To evaluate the subjective well-being feelings of people aged >=50 years in Shanghai by using the Day Reconstruction Method (DRM) and explore the related factors. Methods: A cross-sectional survey was conducted from October 2009 to June 2010 among people aged >=50 years selected through multistage random cluster sampling in Shanghai. DRM was used to assess participants' subjective well-being by net effect and U-index. Univariate and multivariate linear regression models were used to explore the related factors. Results: A total of 8 075 participants were included, with average age of 63.1 years. The mean net effect value was 1.24 (95%CI:1.15-1.33), and the mean U-index was 1.55% (95%CI:1.10%-1.99%). After adjusted for demographic factors, univariate liner regression model indicated that age, education level, marital status, family wealth, residence, self-rated health status, WHODAS score and prevalence of chronic disease were associated with subjective well-being, and multivariate liner regression model indicated that higher WHODAS score was associated with lower net effect value (P<0.05). Conclusion: The subjective well-being feelings of people aged >=50 years in Shanghai might be associated with age, education level, marital status, family wealth, residence, self-rated health status and WHODAS score. Enhanced social support and appropriate social security system might facilitate the improvement of the subjective well-being of the elderly. PMID- 30293307 TI - [Prospective association between childhood abuse experiences and depressive symptoms in adolescence]. AB - Objective: To evaluate the prospective association between childhood abuse experiences and depressive symptoms in adolescence. Methods: Students in grade 3 and 4 from three primary schools were selected, with informed consent, through convenience cluster sampling in Bengbu, Anhui province in May 2013. The students' body height, weight were assessed. Childhood abuse experiences including emotional, physical or sexual abuses, as well as depressive symptoms were reported by children themselves. Data on parental educational background and household economic status were collected through parent questionnaire. A follow up was conducted 4 years later after baseline survey. Depressive symptoms were evaluated by using Children's Depression Inventory at baseline survey, and by using Mood and Feeling Questionnaire at follow-up. Logistic regression model was used to analyze the relationship between childhood abuse experiences and depressive symptoms in adolescence. Results: A total of 1 172 students were included in baseline survey, and a follow-up was conducted for 87.1% of them (n=1 021). Among 1 126 students with complete information on childhood abuse experiences at baseline survey, the reported rates of physical, emotional and sexual abuses were 12.8% (144/1 126), 11.1% (125/1 126) and 10.9% (123/1 126), respectively. The prevalence of depressive symptoms at baseline survey and follow up was 7.0% (82/1 172) and 12.3% (126/1 021), respectively. After adjusted for baseline depressive symptoms, age at follow-up, sex, the only-child in family, household economic status, divorce of parents and BMI, childhood emotional and physical abuse experiences were significant risk factors for depressive symptoms in mid-adolescence, with the ORs were 1.86 (95%CI: 1.03-3.36, P=0.039) and 2.37 (95%CI: 1.39-4.03, P=0.001), respectively. Conclusion: Childhood physical and emotional abuse might increase the risk of depressive symptoms in adolescence. PMID- 30293310 TI - [Association between tea drinking and stroke in adults in Zhejiang province: a prospective study]. AB - Objective: To prospectively explore the association between tea drinking and incidence of stroke of adults of Zhejiang province. Methods: After excluding participants with heart disease, stroke, cancer and diabetes at baseline study, 53 916 participants aged 30-79 years in the China Kadoorie Biobank (CKB) study from Tongxiang were included for final analysis. Cox regression model was used to estimate the hazard ratio (HR) for the association of tea drinking with incident stroke. Results: The main type of drinking tea was black tea (79.78%), followed by green tea (20.08%). Of the 53 916 participants, the proportion of participants who drank tea at least once per week was 31.27%. The corresponding proportions for men and women were 60.24% and 10.30%, respectively. Among 391 512 person years of the follow-up program (median 7.26 years), a total of 1 487 men and 1 769 women were diagnosed with stroke. After adjusting for socio-demographic status, lifestyle, BMI, waist circumference, and systolic blood pressure, HR for incident stroke decreased with the increase of daily average tea consumption amount (P=0.000 6). Compared with participants who did not drink tea weekly, the HRs for incident stroke in those consuming tea 0.1-, 3.0- and >=5.0 g/d were 0.93 (95%CI: 0.85-1.00), 0.88 (95%CI: 0.77-0.99) and 0.79 (95%CI: 0.69-0.89), respectively. The HRs for incident stroke in smokers and non-smokers who consumed tea >=5.0 g/d were 0.71 (95%CI: 0.59-0.86) and 0.97 (95%CI: 0.77-1.21), respectively, compared with current smokers and non-smokers who did not drink tea weekly (P=0.040 0). The corresponding HRs for alcohol drinkers and non-drinkers were 0.96 (95%CI: 0.76-1.22) and 0.70 (95%CI: 0.58-0.84), respectively (P=0.040 0). The corresponding HRs for central obese persons and non-central obese persons were 0.60 (95%CI: 0.44-0.81) and 0.86 (95%CI: 0.73-1.01), respectively (P=0.040 0). Conclusion: Tea drinking had an effect on reducing the possibility of incident stroke, especially among those who were current smokers, non-alcohol drinkers and central obese. PMID- 30293311 TI - [Prevalence of musculoskeletal disorders and related factors in female greenhouse workers in Shandong province]. AB - Objective: To study the prevalence of musculoskeletal disorders (MSDs) and related factors in female greenhouse workers. Method: A questionnaire survey was conducted among 851 female greenhouse workers in Shandong province in 2015. Results: The incidence of MSDs among the female greenhouse workers was 82.79%. For the MSDs in female greenhouse workers, the top four affected body sites were low back (65.82%), knees (49.10%), neck (25.75%) and shoulder (23.47%). Multivariate logistic regression analysis showed that age >=50 years (OR=2.098, 95%CI: 1.353-3.252), working years >=20 (OR=1.703, 95%CI: 1.116-2.599), repetitive work (OR=1.903, 95%CI: 1.183-3.061), standing for prolonged time (OR=2.902, 95%CI: 1.183-7.120) and frequent slightly bending down (OR=2.979, 95%CI: 1.823-4.867) were the main risk factors for MSDs in female greenhouse workers. Aiding tools was the protective factor (OR=0.400, 95%CI:0.229-0.697). Conclusions: The findings showed a relatively higher prevalence of MSDs in female greenhouse workers. It is necessary to take appropriate measures to prevent and control the incidence of MSDs in female greenhouse workers.

AB - Objective: To understand the epidemiologic characteristics of outbreaks, caused by norovirus-GII.2,GII.17 and GII.4/Sydney in Guangdong Province from 2013 to 2017 and to provide scientific evidence for epidemic prevention and control. Methods: Incidence data of norovirus outbreaks in Guangdong from January 1(st) 2013 to November 30(th) 2017 were collected from Public Health Emergency Management Information System. RT-PCR was performed for every case of each outbreak to detect norovirus nucleic acid and gene sequencing was conducted to identify the genotype of norovirus. Characteristics of norovirus GII.2, GII.17 and GII.4/Sydney outbreaks were analyzed. Directly standardized method was used to calculate the proportion of symtoms as diarrhea and vomitting. Results: From January 1(st) 2013 to November 30(th) 2017, a total of 167 norovirus outbreaks were reported in Guangdong, and 115 outbreaks were caused by norovirus GII.2, GII.17 and GII.4/Sydney respectively. The outbreaks caused by norovirus GII.2 accounted for 39.68% (25/63) in primary schools, 28.57% (18/63) in child care settings, 25.40% (16/63) in middle schools and 6.35% (4/63) in universities. Outbreaks caused by norovirus GII.17 accounted for 41.03% (16/39) in middle schools, 20.51% (8/39) at workplaces, 15.38% (6/39) in primary schools, 12.82% (5/39) in universities, 5.13% (2/39) in communities and child care settings respectively. The outbreaks caused by norovirus GII.4/Sydney accounted for 53.85% (7/13) in universities, 15.38% (2/13) in child care settings and at workplaces respectively, 7.69%(1/13) in primary schools and middle schools respectively. The outbreaks caused by norovirus GII.2 had 77.78% (49/63) of contact transmission, 17.46% (11/63) of food-borne transmission. The outbreaks caused by norovirus GII.17 showed 53.85% (21/39) of food-borne transmission, 15.38% (6/39) of contract transmission, 12.82% (5/39) of water-borne transmission. The outbreaks caused by norovirus GII.4/Sydney had 53.85% (7/13) of food-borne transmission, 38.46% (5/13) of the contact transmission. In terms of the clinical manifestations, the standardized proportion of vomit was 73.76% and the proportion of diarrhea was 42.85% in cases infected with norovirus GII.2, the proportion of standardized of vomit was 76.37% and the proportion of diarrhea was 51.40% in cases infected with norovirus GII.17, with the standardized proportion of vomit was 54.10% and the proportion of diarrhea was 55.95% in cases infected with norovirus GII.4/Sydney. Conclusions: The outbreaks caused by norovirus GII.2 through contact transmission mainly occurred in primary schools, child care settings and middle schools.

PMID- 30293313 TI - [Effect of baseline CD(4)(+) T cell count on drop-out of antiretroviral therapy in HIV infected persons in Guangxi Zhuang Autonomous Region, 2008-2015]. AB - Objective: To investigate the effect of baseline CD(4)(+) T cell count (CD(4)) on drop-out of antiretroviral therapy (ART) in HIV infected persons. Methods: Retrospective cohort was conducted in this study. HIV infected persons aged>=18 years and receiving free ART for the first time in Guangxi Zhuang Autonomous Region (Guangxi) from 2008 to 2015 were selected from the antiretroviral treatment database of National Comprehensive HIV/AIDS Information System, with follow-up conducted till May 30, 2016. Cause-specific Cox proportional hazard models were used to evaluate effect of different CD(4) on the drop-out of ART in the HIV infected persons. Results: A total of 58 502 eligible study participants were included in this retrospective cohort study. The average drop-out ratio was 4.8/100 person-years. After controlling the following baseline covariates: age, sex, marital status, route of HIV infection, WHO clinical stage before ART, initial/current ART regiment, ART regiment adjustment, and year of initiating ART for potential confounding, the adjusted HR of drop-out for HIV infected persons with 200- cells/MUl, 351-cells/MUl and >=500 cells/MUl were 1.110 (95%CI: 1.053 1.171, P<0.001), 1.391 (95%CI: 1.278-1.514, P<0.001) and 1.695 (95%CI: 1.497 1.918, P<0.001), respectively, in risk for drop-out compared with those with baseline CD(4)<200 cells/MUl. Among the HIV infected persons, 56.0% (1 601/2 861) of drug withdrawal was due to poor compliance with medication. Conclusions: With the increase of baseline CD(4) when initiating ART, the risk for the drop-out in HIV infected persons increased significantly. To further reduce the drop-out of ART, it is important to take CD(4) into account in initiating ART and to strengthen the health education on treatment compliancy and training for healthcare providers. PMID- 30293315 TI - [Evaluation on follow-up intervention program in men who have sex with men in Tianjin]. AB - Objective: To evaluate the behavior intervention program on men who have sex with men (MSM) in Tianjin. Methods: From April 2013 to September 2017, MSM were enrolled from MSM gathering places and through mobile internet to establish an open prospective cohort. Interventions were conducted in every follow-up meeting, while the changes of behaviors and HIV infection and syphilis incidences in the MSM before and after intervention were compared. Results: A total of 1 822 MSM were interviewed at baseline survey, with 1 007 eligible MSM were enrolled in the cohort. A total of 39 new cases of HIV infection were reported, and the cumulative observation time on cohort follow-up was 2 216.96 person-year, with the HIV incidence rate as 1.76 per 100 person-years. Among them, 934 MSM were sero-negative for syphilis in baseline survey. A total of 100 new cases of syphilis were reported, and the cumulative observation time of cohort follow-up was 1 959.94 person-year, the syphilis incidence rate was 5.10 per 100 person years. With health education and intervention conducted, the awareness rate of AIDS related knowledge for MSM increased. Though the rate of anal sex increased after intervention, the rate of condom use in anal sex increased, too. The rate of condom use decreased after receiving more than 3 interventions. Data from the multivariate GEE analysis indicated that protective factors might be as follows: education level of college and above (aOR=0.81, 95%CI: 0.68-0.98), awareness of AIDS related knowledge (aOR=0.52, 95%CI: 0.36-0.75), ever receiving condom promotion and distribution in the past six months (aOR=0.60, 95%CI: 0.49-0.74), being recruited from mobile internet (aOR=0.85, 95%CI: 0.73-1.00) and times of cumulative intervention: one time (aOR=0.55, 95%CI: 0.45-0.66), two times (aOR=0.38, 95%CI: 0.30-0.49), three times (aOR=0.26, 95%CI: 0.20-0.35), four times and above (aOR=0.24, 95%CI: 0.17-0.33). Diagnoses of STDs in the past six months (aOR=1.43, 95%CI: 1.06-1.96), using rush-poppers (aOR=1.22, 95%CI: 1.02 1.47) might be risk factors. Conclusions: After continuous behavior intervention, the incidence of HIV infection and syphilis were at a low level in the MSM cohort in Tianjin. Their awareness rate of AIDS related knowledge and the rate of condom use increased. But there are still many risk factors influencing the unprotected anal sex in MSM. We should continuously carry out behavioral intervention programs to prevent unprotected anal sex among MSM. PMID- 30293314 TI - [Abuse of diphenoxylate and related factors of forced drug abstainer in Gansu province]. AB - Objective: To investigate the prevalence of diphenoxylate abuse and related factors of forced drug abstainer in Gansu province. Methods: By using a self designed questionnaire, an epidemiologic investigation was carried out among 2 108 forced drug abstainer selected from the compulsory isolation detoxification center of Gansu province. A case-control study was conducted to analyze the factors related with diphenoxylate abuse. Results: The diphenoxylate abuse rate among forced drug abstainer in Gansu was 19.8% (406/2 046), ranking first in medical drug abuse. Multiple logistic regression analysis showed that factors as relieving withdrawal symptoms (OR=2.08, 95%CI: 1.01- 4.32), ways to obtain diphenoxylate (other ways: OR=1.00; regular clinic: OR=27.67, 95%CI: 2.64-289.82; friend: OR=0.01, 95%CI: 0.01-0.03), degree of euphoria (high: OR=1.00; medium: OR =3.36, 95%CI: 1.18-9.55; low: OR=26.16, 95%CI: 10.30-66.42), years of drug abuse (<5 years: OR=1.00; 10-15 years: OR=2.48, 95%CI: 1.02-6.04), abuse at home or in friend's house (OR=3.04, 95%CI: 1.08-8.68), abuse in car (OR=0.05, 95%CI: 0.00 0.68) and detoxification for the first time (OR=0.61, 95%CI: 0.43-0.86) were the possible influencing factors for diphenoxylate abuse. Conclusions: The prevalence of diphenoxylate abuse in forced drug abstainer in Gansu was relatively high. Reasons of abusing, the way to obtain diphenoxylate, whether using drug together with friends, degree of euphoria, years of abuse, abuse place and times for detoxification were related factors influencing the abuse of diphenoxylate. PMID- 30293316 TI - [Current status of national free antiretroviral therapy in interprovincial migrating people living with HIV/AIDS and influencing factors, China, 2011-2015]. AB - Objective: To understand the current status of national free antiretroviral therapy in interprovincial migrating people living with HIV/AIDS (PLWHA) and influencing factors in China. Methods: Descriptive and trend test analyses were performed to evaluate the historical characteristics and trends of main descriptive indicators on national free antiretroviral therapy for the interprovincial migrating PLWHA by using the data collected from National Comprehensive HIV/AIDS Information System from 2011 to 2015. Logistic regression model was used to explore the main factors that influencing the coverage of national free antiretroviral therapy among the interprovincial migrating PLWHA in China. Results: The proportion of interprovincial migrating PLWHA gradually increased in last 5 years from 7.1% (17 784/250 645) in 2011 to 10.3% (54 596/528 226) in 2015 (Z=51.38, P<0.000 1) in China. The coverage rate of free antiretroviral therapy in interprovincial migrating PLWHA increased from 37.3% (6 641/17 784) in 2011 to 71.0% (38 783/54 596) in 2015, showing a significant rising tendency (Z=96.23, P<0.000 1), but it was slightly lower than that in non interprovincial migrating PLWHA in 2015 (71.5%, 338 654/473 630). Multivariate logistic regression analysis showed that the PLWHA who were females, aged >=50 years, of Han ethnic group, married or had spouse, had the educational level of high school or above, infected through homosexual intercourse, with CD(4)(+)T cells counts <=500 cells/MUl at the first visit, identified to be infected with HIV in medical setting, living in urban areas et al, were more likely to receive free antiretroviral therapy. Conclusions: The coverage rate of free antiretroviral therapy varied among the interprovincial migrating PLWHA with different characteristics. It is still necessary to take effective measures to further increase the coverage of free antiretroviral therapy in interprovincial migrating PLWHA and to include the free antiretroviral therapy in interprovincial migrating PLWHA into standardized management system as soon as possible. PMID- 30293317 TI - [Analysis on cardio-metabolic related risk factors in farmers of 15 provinces in China]. AB - Objective: To analyze the prevalence and co-prevalence of cardio-metabolic related risk factors in farmers aged >=18 years in China, to explore the influence of population economic factors on them. Methods: A total of 3 367 farmers, including fishermen or hunters, aged >=18 years were selected as study subjects from the database of Nutritional Status and Health Transition of Chinese Residents Project in 2015. Basic information (age, gender), data on anthropometric (body height, weight and waist size), blood biochemical and socioeconomic (occupation, income, education level and living area) were included. According to the definition of the metabolic syndrome released by the International Diabetes Federation (IDF) in 2005, five cardio-metabolic risk factors appeared as central obesity, increased triglycerides, decreased HDL-C, increased blood pressure and increased plasma glucose. Co-prevalence of risk factors was defined as detecting 2 or more risk factors in a person at the same time. Multivariate logistic regression model was used to analyze the relationship between socioeconomic factors and metabolic risk factors. Results: In 3 367 framers of 15 provinces (autonomous region and municipality), the prevalence rates of central obesity, increased blood pressure, increased plasma glucose, increased triglycerides and decreased HDL-C were 51.8%, 59.0%, 17.0%, 25.5% and 38.7% respectively. Multivariate logistic regression analysis showed that the risks for central obesity (OR=3.69, 95%CI: 3.17-4.28) and decreased HDL-C (OR=3.28, 95%CI: 2.81- 3.82) were higher in women than in men, and the risks for increased blood pressure (OR=0.73, 95%CI: 0.63-0.84), increased blood glucose (OR=0.80, 95%CI: 0.67-0.97) were lower in women than in men. Age was positively correlated with the prevalence or co-prevalence of metabolic risk factors (trend P<0.05). Framers in western China had obviously lower risk for central obesity compared with farmers in central China. No significant correlation was found between farmers' income level, education level or the prevalence of metabolic risk factors. Conclusion: In 15 provinces of China, the prevalence of at least 1 kind of cardio-metabolic risk factor was found in 85.5% of the farmers, and the co-prevalence of cardio-metabolic risk factor was found in 60% of farmers. The prevalence and co-prevalence of cardio-metabolic risk factors were significantly associated with age and gender. It is suggested to take targeted nutritional intervention and health education according to the distribution characteristics of prevalence and co-prevalence of cardio-metabolic factors and strengthen the early prevention and control programs of the diseases. PMID- 30293318 TI - [Study on the status of frailty and related determinants among the elderly in China]. AB - Objective: To investigate the frailty status and related determinants among the elderly in China. Methods: Frailty index (FI) was applied to evaluate the frailty status of the elderly. Data used in this study was from the China Health and Retirement Longitudinal Study (CHARLS) in 2011-2015. Binary logistic regression analysis was carried out to identify the determinants related to the status on frailty. Results: The prevalence rates of frailty in the elderly were 18.7%, 20.6% and 28.4% in 2011, 2013 and 2015, respectively. Being female or elderly under advanced age, were both associated with the higher level of FI. Factors as hip fracture, falls, alcohol intake more than once a month, and less participation in social activities etc., might serve as the risk factors for frailty. Conclusion: Chinese elderly showed relatively high prevalence on frailty and with annual increasing trend. The status of frailty was related to factors as adverse events and unhealthy lifestyles. Comprehensive intervention strategies should be adopted in early life of the elderly to delay the development process of frailty. PMID- 30293319 TI - [Estimation on the health life expectancy of adults in Zhejiang province, 2016]. AB - Objective: To estimate the health-adjusted life expectancy (HALE) of adults in Zhejiang province and evaluate the health status of the adults. Methods: This study was based on the mortality data collected from Zhejiang Chronic Disease Surveillance Information and Management System, and mortality rates from the underreporting survey and self-reported health data in 2016. Hierarchical Ordered Probit (HOPIT) model was used to estimate the severity-weighted prevalence of disability. Sullivan's method was used to calculate the HALE. Results: After adjustment by HOPIT model, the severity-weighted prevalence of disability increased significantly with age (chi(2)=5 795.81,P<0.001), and it was higher in females than in males (chi(2)=5 353.27, P<0.001). The life expectancy and self evaluated HALE were 59.08 years and 48.68 years, respectively, in those aged >=20 years, the difference was 10.40 years due to disability. The proportion of HALE loss due to disability in the total life expectancy was 17.61%, and it increased with age. HALE was higher in males than in females (49.21 years vs. 48.14 years), and in urban residents than in rural residents (49.92 years vs. 47.43 years). Conclusion: The proportion of loss of HALE in the total life expectancy in adults was high in Zhejiang, and it higher in males than in females, in urban residents than rural residents. Programs on improving health care in women and rural residents should be promoted. PMID- 30293320 TI - [Analysis on influencing factors that leading to nonspecific responses to indeterminate results of HIV antibodies]. AB - Objective: To identify the influencing factors that leading to nonspecific responses to indeterminate HIV antibody tests, to provide scientific evidence for the differential diagnosis of HIV infection and control strategy. Methods: A case control study was conducted. The samples of HIV antibody indeterminate in confirmed Western blot (WB) tests, but were negative in HIV nucleic acid tests, were collected as HIV antibody indeterminate group from WB results of HIV confirmatory laboratories of Fujian province in 2015-2016. The general population matched group with HIV antibody screening negative samples and WB negative matched group with WB negative samples were selected as the two compared groups by matching gender and age from HIV antibody screening in Fujian province in the same period. Blood concentrations of hepatitis B surface antigen (HBsAg), anti hepatitis C virus (HCV) antibody, anti-treponema pallidum (TP) antibody, antinuclear antibody (ANA), anti-human T-cell leukemia virus (HTLV) antibody, and alpha-fetoprotein (AFP) were detected by using enzyme-linked immunosorbent assay (ELISA). chi(2) test and multivariate non-conditional logistic regression analysis were performed to identify the influencing factors that leading to nonspecific responses, to indeterminate HIV antibody tests. Results: A total of 13 WB band patterns were observed in 110 HIV antibody indeterminate samples, in which a single p24 band (58.18%, 64/110), a single gp160 band (17.27%, 19/110) and a single p17 band (7.27%, 8/110) were the three most common patterns. The positive rate of anti-TP antibody was significantly higher in HIV antibody indeterminate samples than general population control group and WB negative control group (10.91%, 12/110 vs. 1.77%, 4/226 and 3.64%, 4/110), compared with two control groups (chi(2)=13.627 and 4.314, P<0.05). The positive rate of AFP was significantly higher in HIV antibody indeterminate samples than general population control group (18.18%, 20/110 vs. 0.44%, 1/226, chi(2)=39.736, P<0.05), the different was not significant compared with WB negative control group (18.18%, 20/110 vs. 23.64%, 26/110, chi(2)=0.990, P>0.05) While no significant differences were found between HIV antibody indeterminate group and two control groups in terms of the positive rates of ANA, HBsAg, anti-HCV antibody or anti-HTLV antibody. Conclusions: The influencing factors that leading to nonspecific responses to indeterminate HIV antibody tests appeared complicate, and the anti-TP antibody positivity might be an influencing factor responsible for nonspecific responses to indeterminate HIV antibody tests.

AB - Objective: To explore the association between nuclear factor kappa-light-chain enhancer of activated genetic polymorphisms in B cells (NF-kappaB) and the HCV susceptibility, among the Chinese population. Methods: A total of 1 679 participants were enrolled; including 503 drug users and 1 176 other participants at risk under the exposure for blood. By using the logistic regression analysis, related risk factors for HCV infection among subjects were analyzed. Two NF kappaB pathway variants, NF-kappaB1 rs72696119 and REL rs13031237 were then genotyped by TaqMan assay method. Logistic regression analysis was performed to analyze the association between gene polymorphisms and the susceptibility on HCV. Results: Among the drug users, women (OR=0.408, 95%CI: 0.308-0.767) appeared to be associated with the decreased risk for HCV infection, while factors as drug injection (OR=8.817, 95%CI: 5.577-13.937) and the duration of drug-intake >5.5 years (OR=2.891, 95%CI: 1.824-4.583) were associated with the increased risk for HCV infection. Among the participants who had been exposed to blood, women (OR=3.431, 95%CI: 2.360-4.988) were associated with the increased risk for HCV infection, while the levels of education beyond elementary school (OR=0.613, 95%CI: 0.429-0.876) were associated with the decreased risk for HCV infection. Compared to the reference NF-kappaB1 rs72696119 CC genotype, the carriage of GG genotype was associated with an increased risk of susceptibility on HCV (OR=1.412, 95%CI: 1.035-1.927) among the total study population. Results from the interaction analysis showed that there was no interactive effects appeared between rs72696119 and route of infection, or between rs72696119 and gender among the total population under study (all P>0.05). Conclusion: NF-kappaB1 polymorphism rs72696119 and related factors seemed associated with the susceptibility to HCV infection among high-risk Chinese populations.

AB - Objective: To understand the relationship between AOX1, IRF4 gene methylation status in peripheral blood leukocyte DNA, as well as its interaction with environmental factors, and the risk of breast cancer. Methods: A case-control study was conducted among 401 breast cancer patients and 555 cancer-free controls selected from 2010 to 2014. Methylation sensitive-high resolution melting curve analysis was used to detect the methylation status of AOX1 and IRF4. The multiplication interaction effect between genes' methylation and environmental factors on the risk of breast cancer was analyzed by using unconditional logistic regression, and Excel software was used to analyze the additive interaction effect. Results: Individuals without AOX1 methylation had a 1.37-fold (95%CI: 1.02-1.84) higher breast cancer risk compared to individuals with AOX1 methylation. AOX1 methylation interacted with fungi intake (OR=2.06, 95%CI: 1.12 3.79) and physical activity (OR=2.18, 95%CI: 1.16-4.09) synergistically, on the risk for breast cancer, but no additive interaction effects were observed. Non methylation of IRF4 could increase the risk for breast cancer, with statistical significance (OR=1.71, 95%CI: 0.99-7.43). Neither multiplication nor additive interactions were observed between IRF4 methylation and environmental factors. Conclusion: Non-methylation of AOX1 and IRF4 were a risk factors for breast cancer.

AB - Objective: To analyze the correlation between age and pregnancy-induced hypertension (PIH) in pregnant women from Hebei province in 2016. Methods: A retrospective analysis was conducted by using the clinical data of 64 909 pregnant women, delivering in 22 hospitals in Hebei in 2016. Descriptive statistics was used to describe the general data and pregnancy outcomes of pregnant women, and chi(2) test was used to compare the incidence of PIH in different age groups, and logistic regression analysis was used to analyze the risk factors for PIH. Results: The incidence of PIH was lowest in 20-29 year old women, and increased obviously in those aged<20 and>35 years (P<0.05), and the incidence was positively correlated with age. Logistic regression analysis showed that age, times of pregnancy, number of previous cesarean section and fetus number of current pregnancy were the risk factors for PIH (OR=1.293, 1.153, 1.307, 3.607), while times of deliver and times of prenatal examination were the protective factors (OR=0.655, 0.951). Conclusion: Advanced age pregnancy and young age pregnancy would significantly increase the incidence of PIH. Prenatal care should be strengthened for pregnant women at risk for PIH.

AB - Biomarkers are very useful in the diagnosis and identification of neurocognitive impairments (NCIs) or disorders (NCDs) in HIV-infected individuals, and in particular, blood biomarkers have become more promising because they are cheap and easy to obtain or accept. A systematically literature retrieval was conducted by using PubMed, CNKI, Wanfang and VIP databases for studies about blood biomarkers of neurocognitive impairment of HIV-infected individuals in 2008-2017, according to the inclusion and exclusion criteria. Finally, a total of 43 related articles were included for this systematic review for the purpose of providing scientific evidence for further research and clinical practices. PMID- 30293325 TI - [The Wuhan Twin Birth Cohort Study]. AB - The prevalence of child and adolescent growth and mental-behavior related diseases are increasing, and the pathogenesis are complex. Twins are excellent natural resources for complex chronic diseases research as they share the maternal intrauterine environment, born at the same time and share the same family environment in early years, which could benefit the adjust ment of confounding factors, such as age, genetic factors and early family environmental factors. Birth cohort with twin families involved could be more effective in exploring the genetic and environmental factors for complex chronic diseases at the very beginning of life. This paper summarizes the objective, content, progress, strengths and potential problems of Wuhan Twin Birth Cohort, with emphasis on the overall design and progress of the study.

AB - As the most important phase in standardization activity, implementation saves as the essence. CDC in China are the major institutions undertaking disease control and prevention. Implementing the standards of public health provides technical basis for CDC to complete the task of disease control and prevention. In the study, spot conversation and questionnaire were used to investigate the implementation of standards on public health in CDC. Results showed that the staff of CDC got to know the standards through the Internet. The departments of CDC which conducted training and sent staff to attend training courses accounted for 50.00%(25/50) and 34.00%(17/50), respectively. State mandatory rule is still the main reason for relevant departments to implement the standards of the public health. Government promotion activities facilitate the implementation of Standards, and the degree of familiarity with Standards affects the implementation as well. The paper summarizes the existing problems, such as the lack of coordination between departments of public health at provincial level or below, lack of access to standards, and the need to strengthen the training of the standard implementation etc. It puts forward some suggestions to strengthen the implementation of public health Standards.

PMID- 30293332 TI - [The association of lipid profile and bleeding in patients with minor stroke or transient ischemic attack on antiplatelet therapy: subgroup analysis of CHANCE]. AB - Objective: Abnormalities of lipid profile were considered as risk factors of hemorrhage after ischemic stroke. We aimed to determine the relationship between lipid levels and bleeding in minor stroke or transient ischemic attack (TIA) patients receiving antiplatelet therapy. Methods: Serum total cholesterol, low density lipoprotein cholesterol, high-density lipoprotein cholesterol and triglyceride were tested in a subgroup of 3 044 consecutive patients from Clopidogrel in High-risk patients with Acute Non-disabling Cerebrovascular Events (CHANCE) trial. Patients were randomized to clopidogrel plus aspirin group or single aspirin group. The primary endpoint was any bleeding within 90 days. The secondary endpoint was severe bleeding according to the Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries (GUSTO) definition. Cox proportional hazards models were used to assess the associations of lipid levels and outcomes. Results: A total of 59 (1.9%) bleeding events occurred at 90 days. High-density lipoprotein cholesterol (adjusted HR=2.16; 95%CI 1.17-4.00, P=0.014) and age (adjusted HR=1.04; 95%CI 1.01-1.06, P=0.006) were significantly associated with any bleeding. High-density lipoprotein cholesterol was also associated with severe bleeding (adjusted HR=3.05; 95%CI 1.39-6.68, per 1 mmol/L increase). No correlations between outcomes and levels of total cholesterol, low-density lipoprotein cholesterol and triglyceride were found. There was no interaction of any lipid component level with randomized antiplatelet therapy. Conclusions: Elevated high-density lipoprotein cholesterol is independently associated with any bleeding and severe bleeding in the patients with acute minor stroke or high-risk TIA on antiplatelet therapy. PMID- 30293333 TI - [The efficacy of cognitive behavioral therapy in insomnic patients with or without comorbidities: a pilot study]. AB - Objectives: To evaluate the effectiveness of cognitive behavior therapy for insomnia (CBT-i) in chronic insomnia patients in terms of the improvements of psychological and sleep diary parameters. Methods: Patients who met the diagnostic criteria of chronic insomnia, were divided into primary group or comorbid group. Both groups received standard CBT-i interventions. Psychological scales and sleep diaries were used to evaluate participants' severity of insomnia and psychological conditions related to insomnia at four time points: before intervention (baseline), immediate after intervention, 4 weeks and 16 weeks after intervention. Results: Both groups achieved significant improvements after intervention on psychological measurements and sleep diary parameters. Such improvements were maintained at 4-week and 16-week follow-ups. The sleep diary data indicated that by the end of the intervention, there were significant differences on sleep onset latency (51.72 min to 10.53 min in primary group, P<0.01; 59.26 min to 15.67min in comorbid group, P<0.01) and sleep efficiency (71% to 95% in primary group, P<0.01; 68% to 90% in comorbid group, P<0.01). There were differences on sleep onset latency (10.00 min vs. 13.93 min, P<0.05), total sleep time (355.71 min vs. 327.85 min, P<0.05) and sleep efficiency (95% vs. 91%, P<0.01) in primary group and comorbid group respectively. No differences were found on wake after sleep onset in the two groups. Conclusions: Chronic insomnia patients with or without comorbidities both have improvements after CBT i. Sleep diary parameters rather than psychological measurements are different in two groups. Thus, CBT-i is an effective non-pharmaceutical therapy inpatients with chronic insomnia. PMID- 30293334 TI - [The clinical significance of circulating follicular helper T cells in patients with anti-neutrophil cytoplasmic myeloperoxidase antibody-associated vasculitis]. AB - Objective: To investigate the change of circulating follicular helper T cells (cTfh) in patients with anti-neutrophil cytoplasmic myeloperoxidase antibody associated vasculitis (MPO-AAV), and to analyze the relationship between cTfh and disease activity. Methods: Thirty-eight untreated MPO-AAV patients (patient group) and thirty-eight healthy volunteers (control group) were enrolled in this study. cTfh and membrane expression of inducible co-stimulator (ICOS) and programmed cell death protein 1 (PD-1) were detected by flow cytometry (FCM). Serum anti-neutrophil cytoplasmic myeloperoxidase antibody (MPO-ANCA) was measured by ELISA. Disease activity was evaluated by Birmingham vasculitis activity score (BVAS). Results: Compared with those in control group, the proportions of cTfh, ICOS(+)Tfh and PD-1(+) Tfh cells in patient group were significantly higher [(25.9+/-3.8)% vs. (21.0+/-5.3)%, P<0.001; (1.8+/-0.8)% vs. (0.8+/-0.5)%, P<0.001 and (10.2+/-2.8)% vs. (8.2+/-2.2)%, P=0.001, respectively]. Meanwhile, the expression of ICOS and PD-1 on cTfh in patient group was markedly more intensive (59.6+/-10.0 vs.49.2+/-6.9, P<0.001 and 532.6+/-104.2 vs. 485.1+/ 73.4, P=0.025, respectively). In patient group, the proportion of cTfh was positively correlated with the ratio of ICOS(+)Tfh, the expression of ICOS, the level of MPO-ANCA and BVAS (r=0.407, P=0.011; r=0.705, P<0.001; r=0.737, P<0.001 and r=0.663, P<0.001, respectively). The expression intensity of ICOS on cTfh was positively associated with ICOS(+)Tfh ratio, serum MPO-ANCA and BVAS (r=0.388, P=0.016; r=0.645, P<0.001 and r=0.653, P<0.001, respectively). Nevertheless, the expression of PD-1 on cTfh was only positively correlated with the ratio of PD 1(+) Tfh (r=0.473, P=0.003). Conclusions: Enhanced cTfh in patients with MPO-AAV might produce MPO-ANCA, which is related to the aggravation of MPO-AAV. Thus, cTfh and its ICOS could be potentially targeted for the treatment of MPO-AAV. PMID- 30293335 TI - [Diversity analysis of luminal and mucosa-associated microbial communities in obese mice]. AB - Objective: Gut microbiota have been reported to be able to regulate host metabolism and is closely associated to obesity. The purpose of this study was to explore the differences between the diversity of luminal and mucosa-associated microbial communities in obese mice. Methods: Colonic luminal contents and colonic mucosa were separately collected from 10 obese mice fed with high-fat diet for 12 weeks. DNA of gut microbiota was extracted and micro flora populations were analyzed by Illumina sequencing. Species annotation, diversity analysis, and species difference analysis were conducted. Results: The microbial flora from colonic contents had similar richness, evenness and overall structure to those from colonic mucosa (ACE index 250 vs. 285, Chao index 257 vs. 291, Shannon index 3.84 vs. 3.97, Simpson index 0.05 vs. 0.06, all P>0.05). However, there were differences in the microbial composition on specific levels. At the phylum level, colonic contents had higher abundance of Bacteroidetes (56.08% vs. 27.25%, P=3.21*10(-5)), while colonic mucosa had higher abundance of Firmicutes (49.09% vs. 34.27%, P=0.03) and proteobacteria (18.48% vs. 3.62%, P=0.000 9). At the genus level, butyrate-producing bacteria-Lactobacillus was more abundant in colonic content (LDA score=3.89), whereas gram-negative genus Helicobacter, Sphingomonas and Desulfovibrio were relatively abundant in colonic mucosa (LDA score=4.78, 3.59 and 4.11, respectively). Conclusion: There were differences in microbial composition at the phylum and genus levels between microbial flora from colonic contents and colonic mucosa, although they had similar richness, evenness and overall structure. PMID- 30293336 TI - [The clinical analysis of diabetic patients with chronic inflammatory demyelinating polyradiculoneuropathy]. AB - To explore clinical characteristics, electrophysiological findings and treatment response in diabetic patients with chronic inflammatory demyelinating polyradiculoneuropathy (DM-CIDP). Thirty-six CIDP patients were identified, 10 were DM-CIDP and 26 were non-DM-CIDP. Clinical medical records, electrophysiological data and treatment were retrospectively reviewed. DM-CIDP patients were significantly older than non-DM-CIDP patients [(56.7+/-10.0) years old vs. (40.4+/-16.9) years old, P=0.001]. However, clinical characteristics and abnormalities of electrophysiological tests in both groups were comparable. DM CIDP subjects responded to corticosteroids or intravenous immunoglobulin, thus with better prognosis. PMID- 30293337 TI - [The influence of gender on clinical manifestations of primary hyperparathyroidism]. AB - To explore the impact of gender on presentation of primary hyperparathyroidism (PHPT), clinical data of 150 histopathologically proven PHPT patients were collected and retrospectively analyzed. Most of the patients (72.0%) were parathyroid adenoma (PA), and 9.3% of them were parathyroid carcinoma (PC). In PA patients, albumin-corrected serum calcium levels (TASC) were lower in women than in men [ (2.84+/-0.28) mmol/L vs. (3.03+/-0.34) mmol/L, P=0.006]. In all PHPT subjects, serum urea nitrogen, creatinine, uric acid levels were lower in women than in men. Bone pain was more frequent in women over 50 years old than in men (52.33% vs.29.17%, P=0.045). The incidence of PC was higher in men than in women (20.59% vs. 6.03%, P=0.010). In conclusion, there are gender differences in the clinical presentation of PHPT. TASC was high in men with PA compared to women with PA. Bone pain was more common in the woman patients over 50 years old, and PC was more common in men.

AB - Objective: To investigate the expression of tumor necrosis factor alpha-inducible protein 8 like-2 (TIPE2) and tissue factor (TF) in patients with bronchial asthma. And to explore the regulation of TIPE2 on TF. Methods: Sixty-five asthmatic patients and 40 healthy controls were selected from the First Affiliated Hospital of Zhengzhou University from July to November, 2017. The expression of TIPE2 and TF in peripheral blood mononuclear cells of asthmatic patients and healthy controls were detected by Western blot.The level of TF protein in plasma was detected by enzyme-linked immunosorbent assay. The changes of TIPE2 and TF mRNA expression in THP-1 cells stimulated by house dust mite extract were detected by real-time fluorescence quantitative PCR (RT-PCR). The recombinant adenovirus Adv-TIPE2 was constructed and transfected into THP-1 cells and the effect of over-expression TIPE2 on TF expression in THP-1 cells was detected by RT-PCR. Results: The relative level of TIPE2 protein in asthmatic patients and healthy controls was 0.025+/-0.010 and 0.087+/-0.070, while that of TF was 0.40+/-0.27 and 0.15+/-0.10, respectively. Compared with healthy controls, the levels of TIPE2 protein decreased and TF protein increased in asthmatic patients, the differences were statistically significant (t=-5.06, 9.04, P<0.05) . TIPE2 protein level was negatively correlated with TF protein level (r=-0.460 3, P<0.05). The house dust mite extract reduced the expression level of TIPE2 mRNA in THP-1 cells, but increased the level of TF mRNA expression. When the concentration was 1 MUg/ml, the change of TIPE2 mRNA was the most obvious at 4 h (P<0.05). The recombinant adenovirus Adv-TIPE2 was successfully constructed. The level of TF mRNA expression in THP-1 cells over-expressing TIPE2 gene was reduced (P<0.05). Conclusion: TIPE2, a negative regulator of inflammation, has a negative control effect on TF, and may be involved in the hyper-coagulable state of bronchial asthma by regulating TF expression. PMID- 30293345 TI - [Analysis on the distribution and drug resistance features of anaerobes isolated from clinical infectious specimens]. AB - Objective: To clarify distribution and drug resistance characteristics of anaerobes isolated from clinical infectious samples, and to provide experimental data for guiding on treatment of infections caused by anaerobes. Methods: The anaerobes, isolated from 1 057 different clinical specimens from inpatients admitted to the Affiliated Hospital of Inner Mongolia Medical University from March 2016 to November 2017, were identified by VITEK-2 anaerobes and corynebacterium (ANC) card and bacteroides fragilis isolates were further verified by 16S-rRNA sequencing. Meanwhile, broth dilution method was employed to detect the drug sensititities of bacteroides fragilis and PCR method was used to detect the carbapenem resistance gene cfiA. Results: Totally 303 strains of anaerobic bacteria were isolated, among which 199 strains were gram-negative bacteria, accounted for 65.68%. Among the gram negative anaerobes, bacteroides species were the most common, accounted for 35.64%, followed by prevotella spp., which accounted for 19.14%. B. fragilis were the most common among Bacteroides spp., accounted for 21.54%, followed by Prevotella bivia, accounted for 5.94%. The coincidence rate of 16S-rRNA sequencing results of Bacteroides fragilis and that of ANC card identification results was 100% (65/65). The drug resistance of B. fragilis to penicillin, clidamycin, ampicillin/sulbactam, amoxicillin/clavulanic, were 100%, 90.77%, 56.92% and 66.67%, respectively. The resitance rate of B. fragilis to chloramphenicol was the lowest, which was 1.54%.Moreover, the resistance rate of B. fragilis to imipenem and metronidazole were both higher, which were 38.46%(25/65) and 23.08%(15/65), respectively, and the positive rate of beta lactamase was 100% (65/65). The carrying rate of carbapenems resistance gene cfiA for 65 strains of Bacteroides fragilis was 52.3% (34/65), and 72.00%(18/25)for imipenem resistant strains. Conclusions: The obligate anaerobic bacteria are widely distributed in clinical specimens, and the great majority are gram negative anaerobic bacteria, and the most frequently isolated one is Bacteroides fragilis. Bacteroides fragilis isolates are found to be resistant to several kinds of common antibiotics, especially for imipenem and metronidazole, which should be given more attention to. PMID- 30293346 TI - [Expression of stem cell markers CD44 and Lgr5 in colorectal cancer and its relationship with lymph node and liver metastasis]. AB - Objective: To investigate the relationship between the expression of stem cell markers CD44 and Lgr5 and the clinicopathological features, lymph node and liver metastasis, and to analyse the value of both in evaluating the prognosis of colorectal cancer. Methods: A total of 90 cases of colorectal cancer, 20 cases of adjacent tissues, 30 cases of lymph node metastases, 28 cases of cancer nodules and 30 cases of liver metastasis of colorectal cancer were collected from Department of Pathology of the Second Hospital of Tianjin Medical University from January 2011 to June 2016. The expression of CD44 and Lgr5 protein was detected by immunohistochemistry, and the relationship between them and clinical pathological data, lymph node metastasis and liver metastasis were analyzed. Results: The positive expression rates of CD44 and Lgr5 in colorectal cancer tissues were 68.9% and 62.2%, which were significantly higher than 30.0% and 15.0% of adjacent tissues(P=0.001 and P<0.001). The expression of CD44 and Lgr5 in colorectal cancer was associated with histological differentiation, depth of tumor invasion, lymph node metastasis, soft tissue nodules, hepatic metastasis, and TNM staging(P=0.021, 0.032, 0.030, 0.011, 0.015, 0.007 and P=0.011, 0.027, 0.017, 0.008, 0.011, 0.021). The positive rates of CD44 and Lgr5 expression in lymph node metastases, cancer nodules and liver metastases (93.3%, 89.3%, 90.0%, and 83.3%, 89.3%, 86.7%) were higher than those in the primary lesions(68.9% and 62.2%)(P=0.007, 0.032, 0.022 and P=0.033, 0.007, 0.013). There is a positive correlation between the expression of CD44 and Lgr5 in colorectal cancer(r=0.615, P<0.001), and both positive expression of CD44 and Lgr5 is associated with histological differentiation, lymph node metastasis and cancer nodules, liver metastasis and TNM staging(P=0.005, 0.003, 0.003, 0.026, 0.014). The Kaplan-Meier survival curve showed that the survival rate of positive expression of CD44 and both positive expression of CD44 and Lgr5 in patients with colorectal cancer was low(P=0.030 and 0.001). Log-rank univariate survival analysis showed that histological differentiation, depth of invasion, lymph node metastasis, liver metastasis, and clinical stage were the influencing factors of postoperative survival time(P=0.035, 0.035, 0.018, 0.016, 0.004). Cox proportional hazards regression model multivariate analysis showed that both positive expression of CD44 and Lgr5, lymph node metastasis, liver metastasis, and clinical stage were independent factors affecting the prognosis of patients with colorectal cancer(P=0.004, 0.044, 0.031, 0.008). Conclusions: The expression of CD44 and Lgr5 is related to the malignant biological behavior of colorectal cancer, and they are important factors in promoting local and distant metastases. Both positive expression of them have a hint of bad prognosis. PMID- 30293347 TI - [Associated factors of intraoperative hemodynamic instability in patients with incidental pheochromocytomas]. AB - Objective: To analyze the associated factors of intraoperative hemodynamic instability (HI) in patients with incidental pheochromocytomas. Methods: The data of 104 patients with a pathological diagnosis of pheochromocytoma at Chinese PLA General Hospital between January 2011 and December 2016 was retrospectively analyzed. The patients were divided into hemodynamic stability (HS) group (n=56) and HI group (n=48) according to hemodynamic characteristics. The clinical features, biochemical test, preoperative and intraoperative hemodynamics were analyzed. Multivariate logistic regression analysis was used to explore the associated factors of HI. Results: The age [(44.7+/-12.7) years vs (52.1+/-12.8) years], tumor diameter [(47.9+/-16.3) mm vs (57.9+/-21.6) mm], preoperative blood pressure [(121.3+/-11.5) mmHg vs (127.2+/-13.3) mmHg] in HS group were less than those in HI group (all P<0.05). The proportion of age >= 50 years (28.6% vs 64.6%), tumor diameter >= 45 mm (48.2% vs 68.8%) and hematocrit < 0.38 (25.0% vs 51.3%) in HS group were less than that in HI group (all P<0.05). Multivariate logistic regression analysis indicated that age >= 50 years (OR=7.940, 95% CI: 2.480-25.417, P<0.001), tumor diameter >= 45 mm (OR=5.042, 95% CI: 1.482-17.156, P=0.010), blood pressure >= 130/80 mmHg (OR=3.127, 95% CI: 1.034-9.463, P=0.044) and hematocrit < 0.38 (OR=6.273, 95% CI: 1.893-20.788, P=0.003) were independent associated factors of HI. The proportion of HI ( chi(2)=9.033, P=0.003) and intensive care unit (ICU) admission ( chi(2)=16.641, P<0.001) increased along with increasing associated factors. Conclusion: Adequate preoperative medical preparation and volume expansion for appropriate blood pressure are important for elder patients with large tumor to prevent HI in patients with incidental pheochromocytomas.

AB - Objective: To investigate the clinicopathologic features of lipoprotein glomerulopathy (LPG). Methods: A total of 6 cases (5 males and 1 female, with a mean age of 27.5 years and age range of 11-53 years) of lipoprotein glomerulopathy with complete clinicopathologic data were enrolled. Except for light microscope, immunofluorescence and electron microscopic examination, renal biopsy tissues were checked by oil red O staining. The gene map of apolipoprotein E (ApoE) of 2 cases were analyzed. Results: All 6 cases presented with heavy proteinuria or nephrotic syndrome, and high level of low-density lipoprotein (LDL), very low-density lipoprotein (vLDL), ApoE. Family history of LPG was found in 3 cases, and 2 patients progressed to uremia, or even to death. Pathologic features showed that lipoprotein deposited in glomerulus capillary lumen and renal tubular epithelial cells. Gene analysis demonstrated that 2 cases expressed abnormal ApoE gene (162G>C and 455G>C). Conclusions: Lipoprotein glomerulopathy is autosomal-recessive disease with mutation of ApoE. Common clinical manifestations of LPG are heavy proteinuria or nephrotic syndrome, with a poor prognosis. Renal biopsy pathologic diagnosis can confirm this kidney disease. Emboli of lipoprotein being observed in glomerulus capillary lumen is the pathological feature of LPG.

AB - Objective: To evalute the clinical outcomes of intracytoplasmic sperm injection(ICSI) for infertility male with severe asthenospermia induced by multiple morphological anomalies of the flagella (MMAF). Methods: The clinical data of 15 patient with MMAF were retrospectively analyzed, who underwent ICSI treatment using hyponotic swelling test the "live" sperm in the Department of Reproductive Medicine of Yantai Yuhuangding Hospital from January 2011 to December 2016. Another 30 obstructive azoospermia (OA)patients are matched strictly who also accepted ICSI in the same treatment time. The two groups were compared in the couples'age, the body mass index(BMI), the duration of infertility, the retrieved oocytes, the number of ICSI oocytes, and the rates of fertilization, cleavage, transferrable embryos, good embryos, embryos implanted, clinical pregncncy, early abortion, singleton and twins. Results: After 27 cycles of ICSI, all of the MMAF patients achieved clinical pregnancy, including 11 cases of live birth, 2 cases of spontaneous abortion, and 2 cases of pregnancy maintenance. There were no significant difference between MMAF and OA groups in the couples'age and BMI, or the numbers of retrieved oocytes and ICSI oocytes(P>0.05), but the differences in the infertility duration had statistical meaning(P<0.001). No statistical differences were observed among groups in ICSI fertility rate(92.0% vs 91.6%), clesvage rate(95.4% vs 96.5%), high-quality embryonic rate(56.5% vs 57.5%), good blastocyst rate(23/61 vs 35/94), embryo implantation rate(20/48 vs 35/75), early abortion rate(4/19 vs 8/36), clinical pregncncy rate(15/27 vs 28/50), singleton rate (10/13 vs 20/25)and twinning rate(3/13 vs 5/25)(P>0.05). Conclusions: MMAF may not affect ICSI treatment outcomes, but genetic defects can be transmitted through ICSI. The affected couples should be informed of the necessity of prenatal genetic diagnosis before embryo implantation and the inevitable vertical transmission of genetic problems to the offspring. PMID- 30293350 TI - [Clinical analysis of hereditary coagulation factor V deficiency]. AB - Objective: To analyze the clinical characteristics of hereditary coagulation factor V deficiency (FVD) and to improve the diagnosis and treatment ability of hereditary FVD. Methods: A total of 17 patients with hereditary FVD admitted to the Department of Hematology, Peking University People's Hospital from February 2013 to January 2018 were selected, and their clinical characteristics, laboratory examination, treatment and prognosis were retrospectively analyzed. Results: There were 9 males and 8 females patients with FVD, the median age was 36 (1-72 ) years. The median age of men was 39 (1-72)years, and the median age of women was 33 (8-56)years. There was no significant difference between them (P=0.793). The median prothrombin time(PT) and activated partial thromboplastin time(APTT) values were 21.0(13.0-39.6) s and 54.6(38.2-121.2) s, and the median level of plasma FV was 8.2% (0.9%-39%). Thirteen cases (13/17) were mild, 3 cases (3/17) were moderate, and only 1 case (1/17) was severe according to the FV level. Five cases (5/17) had bleeding, including 3 cases with skin ecchymosis, 1 case with vaginal bleeding, and 1 case with gastrointestinal bleeding. According to the severity of bleeding, 1 case (1/17) had severe bleeding, and the other 4 cases (4/17) were mild bleeding. Conclusions: Patients with hereditary FVD either have or do not have bleeding symptoms, with prolonged PT and APTT and decreased plasma of FV activity. There is no need for treatment for those without bleeding symptoms. Fresh frozen plasma is the first choice for patients who have bleeding, and the overall prognosis is good. PMID- 30293351 TI - [The epidemiological and clinical characteristics of liver hemangioma in health adults]. AB - Objective: To report the epidemiological and clinical characteristics of liver hemangioma in health adults from a large sample of Health Examination Database. Methods: A retrospective study was performed to analyze the epidemiological and clinical Characteristics of liver hemangioma from people who underwent examination in China-Japan friendship hospital from 2014 to 2016. The analysis was also included the relationship between gender or age and the incidence and tumor size. Results: A total of 83 964 healthy adults (age>=18) were included in the study. The overall incidence of liver hemangioma was 2.95%. There was no significant difference of liver hemangiomas incidence between male which was 3.03%, and which was 2.88% in female. Liver hemangiomas incidence had shown obviously increased with patients' age, as the evidence indicating that the prevalence of liver hemangioma in <30 age group was only 1.87%, and the prevalence of liver hemangioma in 41-50 age group raised to 3.72%. While the size of liver hemangioma in different genders was also increasing with age, the tumor size of liver hemangioma in <30 age group was the smallest. Under 50 years old, the size of female patients' liver hemangioma was larger than that of male patients in each age group. The size of female patients' liver hemangioma had obviously decreased over 60 years old. Conclusion: The progress of liver hemangioma was highly influenced by age and gender.

AB - Objective: To evaluate the effect of dexemdetomidine on perioperative inflammatory response and cellular immune in patients undergoing radical operation of thoracoscopic lung cancer. Methods: One hundred and twenty patients undergone radical operation of thoracoscopic lung cancer were randomly divided into control group(group B) and dexemdetomidine group(group A), 60 patients in each group. They were all implemented one-lung ventilation. In group A, dexmedetomidine at a loading dose of 1.0 MUg/kg was intravenously infused starting from 20 min before anesthesia induction, followed by continuous infusion of 0.5 MUg.kg(-1).h(-1) until 20 min before the end of operation. The equal volume of normal saline was given in group B. venous blood samples were collected for determination of the serum concentrations of TNF-alpha, IL-6 and IL-8. peripheral blood T-lymphocyte subsets(CD(3)(+), CD(4)(+), CD(8)(+), CD(4)(+)/CD(8)(+)) and NK cell were also detected at 30 min before anesthesia induction(T(0)), at the end of operation(T(1)), 12 h after operation(T(2)) and 24 h after operation(T(3)). Results: Compared with the T(0, )the plasma concentration of TNF-alpha , IL-6 and IL-8 were increased(P<0.05). The levels of CD(3)(+) and CD(4)(+), CD(4)(+)/CD(8)(+) ratio and NK cells were decreased in both groups at T(1)-T(3)(P<0.05). Compared with group B, the plasma concentration of TNF-alpha , IL-6 and IL-8 were decreased more obviously in group A(P<0.05). The levels of CD(3)(+) and CD(4)(+), CD(4)(+)/CD(8)(+) ratio and NK cells were significantly increased in group A at T(1)-T(3)(P<0.05). Conclusion: Dexemdetomidine can decrease perioperative inflarnmatory response and improve cellular immune function in the patients undergoing radical operation of thoracoscopic lung cancer. PMID- 30293353 TI - [Totally endoscopic sublay repair (TES)--a novel approach to repair midline ventral hernia]. AB - Objective: Investigating a novel approach to treat a midline ventral hernia- totally endoscopic sublay repair (TES). The procedure will be described in detail and the safety and efficacy evaluated. Methods: During July and December 2017, eleven consecutive cases of primary and secondary epigastric midline ventral hernias were repaired using the TES procedure. A large mesh should be placed in the retrorectus position using this minimally invasive procedure. The indications for this procedure include umbilical, epigastric and incisional hernia equal in length to the rectus diastasis. Results: All operations were successful without open conversion. The mean operation time was 120 mins(80-205 min), postoperative pain was mild and the mean VAS was 2.5 on first postoperative day. The average postoperative stay in hospital was 3.3 days (2-5 days). 2 cases experienced postoperative seroma but without adverse effect on the final outcome and no recurrences during the follow-up period of 1 to 6 months. Conclusions: TES procedure is safe, practical and minimally invasive requiring no specific device and highly reproducible. Besides there is no need for expensive anti-adhesion mesh and fixation tacker which make it more cost effective. TES is a good technique for the surgical treatment of midline ventral hernia. PMID- 30293354 TI - [MicroRNA-1249 regulates the apoptosis of myocardial cells in rats with chronic intermittent hypoxia by autophagy]. AB - Objective: To investigate the regulation and possible mechanism of microRNA (miR) 1249 on myocardial apoptosis in chronic intermittent hypoxia rats. Methods: A total of 16male SD rats aged 8 weeks were randomly divided into 2 groups by the random number table: normoxia control group and chronic intermittent hypoxia group (CIH) (n=8 each). The CIH group was exposed to intermittent hypoxia every day from 9: 00 to 17: 00 for 8 consecutive weeks, while the control group received the same frequency of pulse air. Hemodynamic values were measured via a cannula inserted into right common carotid artery. The expressions of miR-1249 and microtubule-associated protein light chain 3 (LC3) mRNA were observed by real time PCR. The expressions of LC3 and Cleaved Caspase-3 were detected by Western bolt. TUNEL staining was performed to detect myocardial apoptosis. The rat cardiomyocyte cell H9C2 was divided into normoxia group, intermittent hypoxia (IH) group and miR-1249 inhibitor transfected and IH treatment group (inhibitor group). At the end of the experiment, the activation of LC3 protein in each group of cells was determined. Results: Compared with normoxia control group, left ventricle end diastolic pressure (LVEDP) increased [(4.6+/-0.4) vs (2.2+/-0.1) mmHg (1 mmHg=0.133 kPa)], left ventricular systolic pressure (LVSP) , maximal rate of pressure decline (-dp/dtmax), and maximal rate of pressure development (+ dp/dtmax) decreased in CIH group [(92.7+/-4.1) vs (135.3+/-3.2) mmHg, (4 247+/ 108) vs (7 626+/-235) mmHg/s, and (3 168+/-105) vs (6 028+/-81) mmHg/s] (all P<0.001). The expression of miR-1249 and LC3 mRNA were significantly higher in CIH group than that in normoxia control group (all P<0.001), and a positive correlation was found between the expression of LC3 mRNA and miR-1249. The expression of LC3 and Cleaved Caspase-3 protein in myocardial tissue of CIH rats were significantly higher than that of the normoxia control group (all P<0.001). The proportion of myocardial cell apoptosis in CIH rats was significantly higher than that in the normoxia control group [(23.84+/-4.94)% vs (2.93+/-0.73)%] (P<0.001). The activation of LC3 in myocardial cells of inhibitor group was significantly lower than that of IH group, but higher than that in normoxia group. Conclusions: CIH could induce LC3 by raising the expression of miR-1249, and then induce the activation of apoptosis protein Caspase3. It ultimately induces myocardial apoptosis.

AB - Traumatic scars not only affect local appearance and function, but also may be accompanied by pain, itching, and even psychological problems, which seriously affect the quality of patients' life. The prevention and treatment of scars are still quite challengeable for plastic and cosmetic surgery. Recently, photoelectric therapy and radio-frequency technology have brought breakthroughs in the clinical prevention and treatment of traumatic scars due to the developments of theory and practice on selective photothermolysis and fractional photothermolysis. Based on the analysis and summary of experience of treatment of traumatic scars with photoelectric therapy and radiofrequency technology in the past 5 years, the experts in the Department of Plastic and Reconstructive Surgery of Shanghai Ninth People's Hospital of Shanghai Jiao Tong University School of Medicine, together with expert consensus on treatment of scar using laser at home and abroad, organize the experts in the field of scar management from different regions in China to discuss and write the consensus on treatment of skin traumatic scars with photoelectric therapy and radio-frequency technology (2018 version). This consensus is suitable for currently medical environment in China and aimed to provide standardized protocols for the treatment of skin traumatic scars in clinic. PMID- 30293362 TI - [Laser and related photoelectric therapies for scar worth expecting]. AB - Effects of non-operative therapies for scar are very limited, and operative treatments are also often difficult to get satisfactory results. Safe, effective, simple, and feasible therapy for scar is urgently needed in clinic. Laser has been used for scar treatment for more than 30 years. There are many kinds of lasers, many of which have been reported to be used for scar treatment. Laser and related photoelectric therapies for scar have experienced long period of exploration, from the initial laser of continuous wavelength to the later pulsed laser, from ordinary spot laser in the early period to the present fractional laser. And there are intense pulsed light closely related to laser and non-light energy of micro-plasma radio-frequency technology. In recent years, with in-depth research of related theories, progress of technology and equipment, as well as accumulation of clinical experience, a great progress has been made in laser treatment for scar. In this article, related theories of photothermal interaction on skin tissue of laser, the present lasers and related photoelectric therapies often used for scar are introduced, and the existing problems and further development directions are also discussed. PMID- 30293363 TI - [Clinical comparative study of pulsed dye laser and ultra-pulsed fractional carbon dioxide laser in the treatment of hypertrophic scars after burns]. AB - Objective: To compare the efficacy and safety of pulsed dye laser (PDL) and ultra pulsed fractional carbon dioxide laser (UFCL) in treating hypertrophic scars after burns. Methods: Two hundred and twenty one patients with hypertrophic scar after burns conforming to the study criteria were admitted to our unit from February 2015 to October 2017, and their data were retrospectively analyzed. Patients were divided into group PDL (n=122) and group UFCL (n=99) according to the treatment method. Patients in group PDL were treated with PDL once every 3-4 weeks. Patients in group UFCL were treated with UFCL once every 6-12 weeks. Patients in both groups were treated until 12 months after having scar. Scars were scored by Vancouver Scar Scale (VSS) before and after treatment. Patients' pain was evaluated by Visual Analogue Scale (VAS) method before and after treatment. Blood flow in scar was monitored and recorded before treatment and in treatment months 6 and 12. Satisfaction degree of patients was recorded 3-6 months after treatment, and the satisfaction rate was calculated. Adverse reactions including duration of erythema/purpura, VAS in treatment, and loss of working time were recorded. Data were processed with one-way analysis of variance, t test, and Chi-square test. Results: (1) VSS scores of patients in groups PDL and UFCL after treatment were significantly lower than those before treatment in the same group (t=11.34, 12.77, P<0.05). The decreasing VSS scores of patients after treatment in groups PDL and UFCL were (5.8+/-1.1) and (6.0+/ 1.4) points, respectively, and there was no statistically significant difference between the two groups (t=1.91, P>0.05). (2) VAS of patients in groups PDL and UFCL after treatment were significantly lower than those before treatment in the same group (t=7.12, 5.23, P<0.05). The decreasing VAS of patients after treatment in groups PDL and UFCL were (4.0+/-0.6) and (3.2+/-1.3) points, respectively, and there was no statistically significant difference between the two groups (t=1.93, P>0.05). (3) Scar blood flow of patients in group PDL in treatment months 6 had no obvious change compared with that before treatment (t=1.59, P>0.05), while that in treatment months 12 significantly decreased compared with that before treatment and that in treatment months 6 (t=3.17, 6.96, P<0.05). Scar blood flow of patients in group UFCL in treatment months 6 significantly increased compared with that before treatment (t=6.01, P<0.05), while that in treatment months 12 significantly decreased compared with that in treatment months 6 (t=4.52, P<0.05), but had no obvious change compared with that before treatment (t=0.92, P>0.05). (4) The satisfaction degree of patients in group PDL was 80.3% (98/122), which in group UFCL was 76.8% (76/99), and there was no statistically significant difference between the two groups (chi(2)=0.97, P>0.05). (5) The duration of erythema/purpura of patients in group PDL was (5.2+/-0.7) d, significantly shorter than (6.1+/-0.5) d in group UFCL (t=2.49, P<0.05). The VAS of patients in group PDL during treatment was (1.9+/-0.9) points, significantly lower than (4.7+/-0.4) points in group UFCL (t=4.85, P<0.05). Loss of working time of patients in group UFCL was (9.17+/-0.72) d, which was significantly longer than (3.96+/-0.23) d in group PDL (t=3.17, P<0.05). Conclusions: PDL and UFCL have definite effects on hypertrophic scar, while PDL with light pain, minor wound, and fast recovery time, is safe and effective for treatment of early hypertrophic scar and worthy of clinical promotion and application, especially for children and patients with poor pain tolerance. PMID- 30293364 TI - [Clinical effects of a combination treatment with narrow-spectrum intense pulsed light and fractional carbon dioxide laser on hypertrophic scar pruritus]. AB - Objective: To observe the effects of a combination treatment with narrow-spectrum intense pulsed light and fractional carbon dioxide laser on hypertrophic scar pruritus in clinic. Methods: A prospective randomized controlled study was conducted. A total of 90 patients with hypertrophic scars conforming to the inclusion criteria who were hospitalized in our ward from March to December 2017 were divided into combination treatment group and control group according to the random number table, with 45 patients in each group. For scar pruritus, patients in control group were treated twice by narrow-spectrum intense pulsed light with a one-month interval, while patients in combination treatment group were firstly treated by narrow-spectrum intense pulsed light combined with fractional carbon dioxide laser once, and with narrow-spectrum intense pulsed light once one month later. Before and 3 months after treatment, scar pruritus was evaluated by the Visual Analogue Scale and the Four-item Itch Questionnaire, and the improvement of scar was assessed by photography. Three months after treatment, the treatment satisfaction of scar pruritus was self-rated by patients. Meanwhile, adverse effects were recorded during the procedures and follow-up periods. Data were processed with Chi-square test, paired t test, Wilcoxon rank-sum test, and Fisher's exact probability test. Results: Before treatment, there was no statistically significant difference in scar pruritus degree evaluated by the Visual Analogue Scale and score distribution of scar pruritus location, extent, frequency, and sleep effect of the Four-item Itch Questionnaire between patients of two groups (Z=-1.08, -0.91, -0.03, -0.69, -1.49, P>0.05). Three months after treatment, there was reducing degree of scar pruritus of patients evaluated by the Visual Analogue Scale in control group or combination treatment group compared with before treatment within the same group (Z=-1.98, -4.65, P<0.05 or P<0.01), while the latter was more obvious than the former (Z=-2.14, P<0.05). There were reducing scores of scar pruritus extent and frequency of patients in control group, along with location, extent, frequency, and sleep effect of patients in combination treatment group compared with those before treatment within the same group (Z=-2.33, -2.34, -3.53, -4.96, -3.32, -4.84, P<0.05 or P<0.01). However, scores of scar pruritus location and sleep effect of patients in control group were similar to those before treatment within the same group (Z= 0.58, -1.34, P>0.05). The scores of scar pruritus location, extent, frequency, and sleep effect of patients were obviously lower in combination treatment group compared with control group (Z=-2.09, -2.69, -1.99, -2.23, P<0.05 or P<0.01). It was much better of scar improvement of patients in combination treatment group compared with control group (Z=-4.00, P<0.01). The percentages of treatment satisfaction of scar pruritus of patients with 0, 1%-25%, 26%-50%, 51%-75%, 76% 100% were 0, 2.2% (1/45), 17.8% (8/45), 48.9% (22/45), and 31.1% (14/45) respectively in combination treatment group, which were obviously better than 0, 11.1% (5/45), 53.3% (24/45), 28.9% (13/45), and 6.7% (3/45) in control group (Z= 4.42, P<0.01). During the treatment and follow-up periods, the adverse effect ratio of patients in control group was 6.7% (3/45), similar to 2.2% (1/45) of combination treatment group (P>0.05). Conclusions: The combination of narrow spectrum intense pulsed light and fractional carbon dioxide laser can greatly reduce pruritus, improve effect of scar treatment, and bring higher patient satisfaction compared with narrow-spectrum intense pulsed light alone in treating hypertrophic scar pruritus.

AB - Objective: To observe the clinical effects of sequential treatments of pulsed dye laser (PDL) and ablative fractional carbon dioxide laser on early stage hypertrophic burn scars. Methods: From January 2016 to December 2017, 221 patients with 228 hypertrophic scars in all parts of body within 6 months post healing, conforming to the study criteria and treated in our department, were included in this prospective study. They were first treated by PDL, repeated at an interval of one month until the vascularity score of scar fell below 2 points, and then treated by ablative fractional carbon dioxide laser, repeated at an interval of 3 months. Their start time and numbers of treatment and follow-up time were recorded. Before the first treatment (hereinafter referred to as before treatment) and at the last follow-up (hereinafter referred to as after treatment), the vascularity, thickness, and pliability of scars were scored by a self-made scar rating scale. The scores of patients with the observation time between 6 to18 months post healing were compared among scars of patients grouped by age, body site of scar, starting time of treatment and numbers of treatment. The laser speckle contrast imaging technique was used to measure the blood flow value of scars. The itching symptom of the scars was evaluated by the Verbal Rating Scale. The satisfaction to the final effects of the doctors and patients was investigated and scored separately by Likert scale after treatment. The therapeutic or adverse reactions were recorded during the treatment. Data were processed with paired t test, Mann-Whitney U test, Wilcoxon signed rank sum test, Kruskal-Wallis H test, and Spearman rank correlation analysis. Results: (1) The patients were treated on (64+/-36) d post healing, by PDL for (2.5+/-1.3) times and by ablative fractional carbon dioxide laser for (2.2+/-1.2) times. The follow up time was (331+/-189) d. (2) The vascularity, thickness, pliability scores and total scores of scars were (1.4+/-0.9), (2.0+/-0.8), (1.7+/-0.8), and (5.0+/-2.1) points respectively after treatment, which were significantly lower than those before treatment [(4.1+/-0.7), (3.1+/-0.8), (3.0+/-0.9), and (10.2+/-2.0) points respectively, t=43.332, 24.968, 28.063, 46.394, P<0.01]. (3) Among the 123 scars from 120 patients with observation time between 6 to 18 months post healing, there were no statistically significant differences in the vascularity, thickness, pliability scores and total scores of scars among patients with different ages after treatment (chi(2)=4.339, 1.826, 1.375, 2.879, P>0.05). There was only significant difference in the pliability scores of scars among different body sites (chi(2)=13.530, P<0.05). There were statistically significant differences in the vascularity, thickness, pliability scores and total scores of scars with different starting time of treatment (chi(2)=30.725, 25.233, 25.119, 35.798, P<0.01). There were significantly positive correlation between starting time of treatment and the vascularity, thickness, pliability scores and total scores of scars (r=0.492, 0.442, 0.446, 0.532, P<0.01). There were statistically significant differences in the vascularity, pliability scores and total scores of scars with different numbers of treatment (Z=4.883, 4.910, 5.049, P<0.05). There were significantly negative correlation between number of treatment and the vascularity, thickness, pliability scores and total scores of scars (r=-0.176, 0.131, -0.191, -0.201, P<0.05). (4) The blood flow values were determined in 18 scars of 18 patients. The results showed that the blood flow values of scars after treatment were significantly decreased compared with those before treatment (t=7.230, P<0.01). (5) The pruritus scores of scars of patients after treatment were significantly decreased compared with those before treatment (Z=12.818, P<0.01). (6) There were significant differences between the satisfaction scores of doctors and the scores of patients after treatment (t=12.130, P<0.01). (7) After PDL treatment, there were some edema and purpura reactions for all the patients, and 11 (5.0%) patients had blisters. After ablative fractional carbon dioxide laser treatment, 4 (1.8%) patients had blisters, 5 (2.3%) patients suffered inflammatory reaction and erosion, and 9 (4.1%) patients suffered pigmentation. Conclusions: The scores of hypertrophic burn scars can be obviously improved by sequential treatments of PDL and ablative fractional carbon dioxide laser. The effects can be more obvious with the earlier starting time and more numbers of treatment. The laser treatments can also decrease the blood flow values and alleviate the pruritus of scars, with high satisfaction of both patients and doctors.

AB - Objective: To observe the distribution of occupational activity disorders of extremely severe mass burn patients in recovery period after injury. Methods: From December 2014 to December 2015, 65 extremely severe burn patients conforming to the inclusion criteria involved in August 2 Kunshan factory aluminum dust explosion accident were admitted to Kunshan Rehabilitation Hospital. They received comprehensive rehabilitation treatment after burns, including wearing pressure clothes, ultrasound treatment, semiconductor laser and red light irradiation, motor function training, and so on. Over 2 years after injury, a cross-sectional survey was conducted on the patients' occupational activity disorders. Modified Barthel index (MBI) was used to assess the degree of activities of daily living (ADL) disorder of patients and to grade the independent level of completing each item of MBI, and then the independent level of patients completing self-care MBI items (bathing, dressing, grooming, eating, going to the toilet, urine control, and stool control) was compared with that of mobility items (going up and down stairs, bed and chair transfer, and walking). The Canadian Occupational Performance Measure (COPM) was used to assess the distribution of occupational activity disorders of patients. The distribution of the five most serious occupational activity disorders was counted, then the frequency and probability of which with frequency greater than or equal to 16 times were calculated. Data were processed with Pearson Chi-square test. Results: Over 2 years after injury, the MBI score of patients was (76+/-22) points, and the ADL of 83.08% (54/65) patients reached completely self-care or light ADL disorder level. The MBI items arranged according to the completing independent level of patients from high to low were urine control/stool control, walking, bed and chair transfer, going up and down stairs, going to the toilet, eating, grooming, dressing, and bathing. The independent level of patients completing self-care MBI items was lower than that of mobility items (chi(2)=62.298, P<0.001). Over 2 years after injury, the five most serious occupational activity disorders in COPM dimension were mainly concentrated in the self-care dimension, accounting for 55.38% (180/325), followed by 22.46% (73/325) of production activities and 22.15% (72/325) of recreational activities, and the centrally distributed item was the personal self-care item under self-care dimension, accounting for 42.46% (138/325). Over 2 years after injury, the five most serious occupational activity disorders with frequency greater than or equal to 16 times were dressing and undressing, bathing, perineal cleaning, wearing pressure clothes, caring for children, visiting relatives and friends, 31, 25, 16, 17, 18, and 22 times respectively, with a probability of 47.69%, 38.46%, 24.62%, 26.15%, 27.69%, and 33.85% respectively. Conclusions: Over 2 years after injury, most of the patients with extremely severe burns caused by the aluminum dust explosion were completely or basically self-care in their daily life. The disorder of self care ADL was more serious than that of mobility, and the disorder of individual self-care activity was still the most serious occupational activity disorder of patients in this stage.

PMID- 30293367 TI - [Influences of hydrogen-rich saline on acute kidney injury in severely burned rats and mechanism]. AB - Objective: To explore the influences of hydrogen-rich saline on acute kidney injury in severely burned rats and to analyze the related mechanism. Methods: Fifty-six Sprague Dawley rats were divided into sham injury group (n=8), burn group (n=24), and hydrogen-rich saline group (n=24) according to the random number table. Rats in sham injury group were treated by 20 C water bath on the back for 15 s to simulate injury, and rats in burn group and hydrogen-rich saline group were inflicted with 30% total body surface area (TBSA) full-thickness scald (hereinafter referred to as burns) by 100 C water bath on the back for 15 s. Immediately after injury, hydrogen-rich saline at the dose of 10 mL/kg were intraperitoneally injected to the rats in hydrogen-rich saline group at one time, while normal saline with the same dose were intraperitoneally injected to the rats in sham injury group and burn group. At post injury hour (PIH) 6, rats in the 3 groups were intraperitoneally injected with 4 mL.kg(-1).%TBSA(-1) lactated Ringer's solution for resuscitation. Eight rats from sham injury group at PIH 72 and eight rats from burn group and hydrogen-rich saline group at PIH 6, 24, and 72 were sacrificed respectively after their blood samples from abdominal aorta were collected. Then their kidney tissue was harvested for histopathological observation and renal tubular injury scoring by hematoxylin and eosin staining, serum creatinine and blood urea nitrogen were detected by the clinical blood biochemical analyzer, expression distribution and mRNA expressions of tumor necrosis factor alpha (TNF-alpha), interleukin-1beta (IL-1beta), and IL-6 in renal tissue were evaluated by immunohistochemical staining and real time fluorescent quantitive reverse transcription polymerase chain reaction respectively, and protein expression of high mobility group protein 1 (HMGB1) was detected by Western blotting. Data were processed with Kruskal-Wallis H test, Dunn test, one-way analysis of variance, Bonferroni test. Results: (1) The renal tubular structure of rats in sham injury group at PIH 72 was complete with no inflammatory cell infiltration and no cellular degeneration or necrosis. Since PIH 6, the changes such as vacuolation and shape change of cells and aggregation of broken protein in renal tubules were observed in rats of burn group, and all these changes deteriorated with time. The renal injury of rats in hydrogen-rich saline group at different post injury time points were relieved compared with those of rats in burn group at the corresponding time points. The renal tubular injury scores of rats in burn group and hydrogen-rich saline group at PIH 6, 24, and 72 were significantly higher than the score in sham injury group at PIH 72 (P<0.05). The renal tubular injury scores of rats in hydrogen-rich saline group were significantly lower than those in burn group at PIH 6, 24, and 72 (P<0.05). (2) Except for those in hydrogen-rich saline group at PIH 6 and 72 (P>0.05), the levels of serum creatinine of rats in burn group at all the time points and hydrogen-rich saline group at the other time points were significantly higher than the level of serum creatinine of rats in sham injury group at PIH 72 (P<0.01). The levels of blood urea nitrogen of rats in burn group and hydrogen rich saline group at PIH 6, 24, and 72 were significantly higher than the level of blood urea nitrogen of rats in sham injury group at PIH 72 (P<0.01). The levels of serum creatinine and blood urea nitrogen of rats in hydrogen-rich saline group at PIH 6, 24, and 72 were significantly lower than those in burn group at the corresponding time points (P<0.05). (3) There were certain degree of positive expressions of TNF-alpha, IL-1beta, and IL-6 in renal tissue of rats in sham injury group at PIH 72, which were mainly observed in the cytoplasm of renal tubular epithelium cell. The expressions of above-mentioned inflammatory cytokines in renal tissue of rats in burn group at PIH 6, 24, and 72 were higher than those in sham injury group. The expressions of above-mentioned inflammatory cytokines in renal tissue of rats in hydrogen-rich saline group at all the time points were less than those in burn group at the corresponding time points. (4) Compared with those in sham injury group at PIH 72, the mRNA expression levels of TNF-alpha, IL-1beta, and IL-6 of rats in burn group at PIH 6, 24, and 72 were significantly increased (P<0.01). The mRNA expression levels of TNF-alpha were significantly increased in hydrogen-rich saline group at PIH 6 and 24 (P<0.05 or P<0.01), and the mRNA expression level of IL-6 was significantly increased in hydrogen-rich saline group at PIH 6 (P<0.01). Compared with those at the corresponding time points in burn group, except for the mRNA expression level of TNF-alpha in hydrogen-rich saline group at PIH 6 showed no significant differences (P>0.05), and the mRNA expression levels of TNF-alpha, IL-1beta, and IL-6 at the other time points in hydrogen-rich saline group were significantly decreased (P<0.05). (5) Compared with 0.39+/-0.03 in sham injury group at PIH 72, the protein expression of HMGB1 of rats in burn group at PIH 6, 24, and 72 (1.19+/-0.07, 1.00+/-0.06, 0.80+/-0.05) were significantly increased (P<0.05), while the protein expression of HMGB1 of rats in hydrogen-rich saline group at PIH 6, 24, and 72 (0.35+/-0.08, 0.47+/-0.06, 0.42+/-0.06) showed no significant differences (P>0.05). Compared with those in burn group, the protein expressions of HMGB1 of rats in hydrogen-rich saline group at PIH 6, 24, and 72 were significantly decreased (P<0.05). Conclusions: Hydrogen-rich saline can alleviate the acute kidney injury in severely burned rats through regulating the release of inflammatory cytokines in renal tissue. PMID- 30293368 TI - [Clinical application of platelet-rich fibrin in chronic wounds combined with subcutaneous stalking sinus]. AB - Objective: To investigate the clinical effect of platelet-rich fibrin (PRF) in the treatment of chronic wounds combined with subcutaneous stalking sinus caused by various kinds of reasons. Methods: The clinical data of 72 patients with chronic wounds and combined with subcutaneous stalking sinus caused by various kinds of reasons admitted to our unit from June 2015 to February 2017, conforming to the study criteria, were collected and retrospectively analyzed. Patients were divided into group PRF (n=39) and routine dressing change (RDC) group (n=33) according to their treatment. The subcutaneous stalking sinuses of patients in group PRF were filled with PRF 1 or 2 times after debridement, while the surface of wound was covered by vaseline gauze and aseptic dressing, and dressing change was performed once per 2-3 days. The wounds of patients in group RDC were filled with iodine gauze after debridement of wounds and wrapped up with conventional aseptic dressing, and dressing change was performed once per 0.5-2.0 days. The times of operation, the times of dressing change, the time for negative conversing of bacteria culture in the secretion of wound, the time of subcutaneous stalking sinus closure, and the complete healing time of wounds of patients in two groups were recorded. Data were processed with Chi-square test and independent sample t test. Results: The operation times of patients in two groups were close (t=0.565, P>0.05). The dressing changes of patients in group PRF were (6.4+/-2.1) times, significantly less than (19.2+/-6.2) times in group RDC, t=12.107, P<0.01. The time for negative-conversing of bacteria culture in the secretion of wound of patients in group PRF was (15+/-5) d, significantly shorter than (25+/-9) d in group RDC, t=6.087, P<0.01. The time of subcutaneous stalking sinus closure of patients in group PRF was (12+/-5) d, significantly shorter than (24+/-8) d in group RDC, t=7.315, P<0.01. The complete healing time of wounds of patients in group PRF was (23+/-7) d, significantly shorter than (35+/-10) d in group RDC, t=5.924, P<0.01. All the chronic wounds of patients in two groups were completely healed, and there were no break or new sinus formed during the follow-up of 4-12 months after discharge. Conclusions: The application of PRF in the treatment of chronic wounds combined with subcutaneous stalking sinus caused by various reasons can bring about rapidly healing of wounds, definite effect, and convenient operation, thus is worth promoting and applying in clinic. PMID- 30293369 TI - [Mutations in A((8)) and A((9)) loci of exon 8 of retinoblastoma protein interacting zinc finger gene of keloid patients]. AB - Objective: To study the situation of the mutations in the A((8)) and A((9)) loci of exon 8 of retinoblastoma protein-interacting zinc finger gene (RIZ) of keloid patients. Methods: From January 2003 to December 2007, 19 outpatient and hospitalized keloid patients of our hospital were conforming to the inclusion criteria. Both 3-5 g keloid tissue and 3 mL peripheral venous blood were collected from each patient to extract their genomic DNA, and the concentration was determined. The A((8)) and A((9)) loci fragments of exon 8 of RIZ were amplified by polymerase chain reaction (PCR). The length of product was detected by agarose gel electrophoresis, and DNA sequencing was performed after column chromatography. The mutations of A((8)) and A((9)) loci fragments were searched, and the types of mutations were determined. The consistency of genetic mutations of the keloid tissue and peripheral venous blood were compared. Data were processed with McNemar test. Results: The DNA concentrations of the extracted keloid tissue and peripheral venous blood were 0.54 and 0.37 MUg/MUL, respectively, which were above 0.10 MUg/MUL. The lengths of PCR products of A((8)) locus fragment DNA of exon 8 of RIZ from keloid tissue and peripheral venous blood were 235 and 238 bp, respectively, and those of A((9)) locus were 242 and 244 bp, respectively, which were basically the same as the designed DNA fragments. PCR products purity of A((8)) locus fragment DNA of exon 8 of RIZ from keloid tissue and peripheral venous blood were 1.81 and 1.75, respectively, and those of A((9)) locus were 1.82 and 1.78, respectively, which were above 1.50. Mutations in the A((8)) locus of exon 8 of RIZ were observed in keloid tissue of 18 patients, totally 6 gene mutations, including 4 point mutations and 2 frameshift mutations. Mutations in the A((9)) locus of exon 8 of RIZ were observed in keloid tissue of 9 patients, totally 9 gene mutations, including 7 point mutations and 2 frameshift mutations. No patient had a mutation in the A((8)) or A((9)) locus of exon 8 of RIZ in peripheral venous blood. Compared with those of peripheral venous blood, the mutations in the A((8)) and A((9)) loci of exon 8 of RIZ in keloid tissue of patients were statistically significant (chi(2)=16.06, 7.11, P<0.05). Conclusions: Point mutations and frameshift mutations occur in the A((8)) and A((9)) loci of exon 8 of RIZ in keloids of patients, which may be associated with the occurrence of keloids. PMID- 30293370 TI - [Influences of comprehensive nursing intervention on the caregivers of severely burned children]. AB - Objective: To explore the influences of comprehensive nursing intervention on the caregivers of severely burned children. Methods: Eighty severely burned children, admitted to our department from November 2016 to November 2017 and conforming to the study criteria, were included in this study. They were divided into comprehensive group and control group according to the random number table, with 40 children in each group. One caregiver for each child was included in the same group. Children and caregivers in control group had routine nursing care while children and caregivers in comprehensive group had comprehensive nursing care on the base of routine nursing care, including comprehensive psychological nursing of children and caregivers, guidance of rehabilitation for caregivers throughout the entire recovery process, individualized propaganda and education for caregivers on account of disease of children, perfecting social support system, sustained attention of children during follow-up. Anxiety self-rating scale and social support rating scale were used to assess the levels of anxiety and social support of caregivers of children in the two groups at the time of admission (before intervention) and the second month after discharge (the third time follow up, after intervention). On the day of discharge, the nursing service satisfaction questionnaire of our department was used to evaluate the nursing service satisfaction of caregivers of children. Data were processed with chi square test and independent sample t test. Results: (1) Before intervention, the anxiety and social support scores of caregivers of children in control group were respectively (64.5+/-3.8) and (40.4+/-2.5) points, similar to (63.5+/-4.9) and (40.5+/-2.6) points in comprehensive group (t=0.988, 0.177, P>0.05). After intervention, the anxiety score [(47.2+/-1.9) points] of caregivers of children in comprehensive group was significantly lower than that of control group [(57.6+/-4.3) points, t=13.917, P<0.01], and the social support score [(45.3+/ 1.9) points] was significantly higher than (35.9+/-2.1) points in control group (t=-21.282, P<0.01). After intervention, scores of objective support, subjective support, and social support utilization in the social support evaluation rating of caregivers of children in comprehensive group were significantly higher than those in control group (t=12.678, -11.079, -10.031, P<0.01). (2) At the time of discharge, scores of clinical care, propaganda and education content and form in the nursing service satisfaction questionnaire of caregivers of children in comprehensive group were significantly higher than those of control group (t= 14.757, -15.627, -33.221, P<0.01). Conclusions: Comprehensive nursing intervention method can effectively reduce the anxiety of the caregivers of severely burned children, help them to make better use of social support system, and improve the satisfaction of caregivers in nursing services.

PMID- 30293371 TI - [Advances in the research of influence of diabetes in biological function of adipose-derived stem cells]. AB - Adipose-derived stem cells (ADSCs) are adult mesenchymal stem cells in adipose tissue with self-renewal and multi-directional differentiation potential. The application of ADSCs in the treatment of wounds has achieved good results. Because of its extensive sources, high content in vivo, low immunogenicity, slight injury to body when obtained, the clinical application prospect of ADSCs is promising. The reasons why diabetic wound is difficult to heal may be closely related to the increase of advanced glycation end products, long-term chronic inflammatory response, and peripheral neurologic dysfunction. The abnormal internal environment of diabetic patients can affect the biological function of ADSCs, which further affects wound healing. This article reviews the general feature, differentiation, proliferation, migration, secretion, and pro-angiogenic function of diabetic ADSCs.

PMID- 30293375 TI - [Association between long-term blood pressure change and the incidence of cardiovascular diseases: a population-based cohort study]. AB - Objective: To explore the association between long-term changes in blood pressure (BP) levels and the incidence of cardiovascular diseases (CVD). Methods: A total of 5 752 participants, who participated baseline examination in 1992-1993 and re examination in 2007, were followed up till December 31, 2013 according to the study protocol of the Chinese Multi-provincial Cohort Study. Participants were stratified by baseline BP and re-examination BP and cross-combined into 9 subgroups. The 20-year incidence of acute cardiovascular events, acute coronary heart disease (CHD) and acute stroke events were analyzed and association between disease incidence and 15-year changes in BP were determined using the competing risk regression model. Results: (1) There were 523 CVD events (170 CHD, 373 stroke) during the 20 years follow up. The number of participants with baseline systolic blood pressure (SBP)/diastolic blood pressure (DBP) of <130/80 mmHg (1 mmHg=0.133 kPa), 130-139/80-89 mmHg, and hypertension were 2 892 (50.3%), 1 328 (23.1%) and 1 532 (26.6%), respectively. (2) Among participants with baseline SBP of 130-139 mmHg or DBP of 80-89 mmHg, 870 (65.5%) progressed to hypertension and 279 (21.0%) maintained at the same stratum over a 15-year follow up period. (3) After adjustment for age, sex, body mass index, smoking status, diabetes, total cholesterol, and high-density lipoprotein cholesterol at baseline, participants maintained SBP/DBP at 130-139/80-89 mmHg had a higher risk of developing acute cardiovascular events, CHD and stroke with the hazard ratios (HR) and 95% confidence interval (95%CI) of 2.04 (1.16, 3.57), 3.29 (1.30, 8.35) and 1.63 (0.80, 3.33), compared with those who maintained their SBP < 130 mmHg and DBP <80 mmHg. Participants whose BP increased from 130-139/80-89 mmHg to hypertension over the follow up period had 2.81-fold (1.84, 4.29), 3.17-fold (1.43, 7.03) and 2.71-fold (1.65, 4.44) higher risk for the incidence of acute cardiovascular events, CHD, and stroke, respectively, compared with participants who maintained their SBP <130 mmHg and DBP <80 mmHg. Conclusions: Participants with SBP/DBP of 130-139/80-89 mmHg have a high long-term risk for progression to hypertension. Sustained exposure to SBP/DBP of 130-139/80-89 mmHg or higher increases the risk of CVD incidence, and our results highlight the importance of early prevention for participants with this BP stratum. PMID- 30293376 TI - [Mediating effect of hemoglobin and hematocrit on the association between alcohol consumption and blood pressure among middle-aged and elderly male residents in Guangzhou]. AB - Objective: To explore the mediating effect of hemoglobin (Hb) and hematocrit (HCT) on the association between alcohol consumption and blood pressure, and provide evidence for the prevention and control of alcohol-attributed hypertension. Methods: 1 091 male (age >50 years old) participants with drinking habit were selected from the Guangzhou biobank cohort study (GBCS). Mediation analysis was used to evaluate the mediating effect of Hb and HCT on the association of alcohol consumption (unit/day) with systolic blood pressure (SBP), diastolic blood pressure(DBP), pulse pressure(PP) and mean arterial pressure (MAP). Results: After adjusting for age, body mass index, education level, personal annual income, smoking, occupation and physical activity, the associations of alcohol consumption with SBP, DBP, PP and MAP were partly mediated by Hb, the proportion of mediating effect was 11.8% (95%CI 4.8%-24.7%), 15.3% (95%CI 6.5%-32.0%), 8.4% (95%CI 2.2%-22.5%) and 13.5% (95%CI 5.9%-27.5%), respectively. The associations of alcohol consumption with SBP, DBP, and MAP were also partly mediated by HCT, the proportion of mediating effect was 6.3% (95%CI 1.0%-16.0%), 8.7% (95%CI 1.4%-21.4%), and 7.5% (95%CI 1.0%-18.6%), respectively. Conclusion: There is a significant mediating effect of Hb and HCT on the association between alcohol consumption and blood pressure. Besides efforts on alcohol control, the potential effects of alcohol-induced increase on Hb and HCT, which might also increase the blood pressure, need to be considered to achieve optimal monitoring and prevention of alcohol-related hypertension. PMID- 30293377 TI - [Analysis of structural features of gut microbiota in two-kidney-one-clip hypertensive rats based on high-throughput sequencing technology]. AB - Objective: To characterize the gut microbial community structure of two-kidney one-clip (2K1C) hypertensive rats, provide new evidences for prevention and treatment of hypertension. Methods: Adult male SD rats were divided into 2K1C hypertensive model group and sham operation group (n=8 each). Blood pressure was recorded by tail-cuff technique weekly for 4 weeks. Then, the total fecal DNA of rats in 2K1C model group and sham operation group were extracted. The structure and principal components of intestinal flora in 2K1C model rats and sham operated rats were analyzed using Hiseq3000 sequencing platform. Additionally, real time fluorescent quantitative polymerase chain reaction technology was used to detect the content of predominant bacteria, including Escherichia, Bifidobacterium, Lactobacillus and Bacteroides. Results: Compared with sham operation group, significant reduction in the relative abundance of Firmicutes (31.72 (30.06, 32.18) vs. 40.99 (38.78, 44.41), U=0.00, P<0.05) and increase in Bacteroidetes (48.13(41.16,50.25) vs. 27.81(25.84,31.38),U=0.00, P<0.05) were observed in the fecal samples from model group. The relative abundance of Escherichia coli (0.08(0.07,0.11) vs. 0.07(0.06,0.08),U=12.50, P<0.05) was increased and the short chain fatty acid producing strains such as Coprococcus, Roseburia, Blautia, Clostridium and Bacteroides was reduced in 2K1C model group than in sham operation group (all P<0.05). Moreover, the relative abundance of Prevotella (Bacteroidetes) was also significantly higher in 2K1C model group than in sham operation group (18.14(17.78,18.75) vs.1.83(1.50,5.19), U=0.00, P<0.05). Moreover, the relative abundance of Ruminococcus (Firmicutes) was significant higher in 2K1C model group than in sham operation group (7.73(6.04,9.34) vs. 3.68(2.46,4.67),U=0.00, P<0.05). Principal coordinate analysis showed that there was significant difference in the gut microbial community structure between 2K1C model group and sham operation group. Conclusion: There are significant changes in the gut microbial community structure in 2K1C model group as compared to sham operation group, indicating renovascular hypertension might affect gut microbial community structure in this rat model.

AB - Objective: To explore the relation between platelet-to-lymphocyte ratio (PLR) or neutrophil-to-lymphocyte ratio (NLR) with disease activity in Takayasu arteritis (TA) patients. Methods: Present retrospective study involved 289 patients with TA, who were hospitalized in our department between January 2010 and October 2017, and 280 age and gender matched healthy controls,who underwent thealth examination in our health examination center during the same period (control group). TA patients were further divided into active and inactive groups (180 and 109 cases respectively) according to Kerr scores. The clinical data were compared between groups. Pearson correlation analysis was used to evaluate the relationship between PLR or NLR and disease activity (Kerr score or C-reactive protein or erythrocyte sedimentation rate). Receiver operating characteristic (ROC) curve was employed to judge the cut-off value of disease activity for TA patients. Results: PLR and NLR were significantly higher in TA group than in control group(137.33 (97.38, 193.37) vs. 120.55 (96.86, 144.60) and 2.38 (1.76, 3.57) vs. 1.66 (1.35, 2.08) , respectively, all P<0.001). PLR and NLR were significantly higher in active TA group than in inactive TA group (163.43 (123.64, 224.15) vs. 110.53 (84.22, 147.24) and 2.59 (1.96, 3.94) vs. 1.95 (1.53, 2.86) respectively, all P<0.001). PLR and NLR of active group were significantly decreased after 6 months treatment (164.05 (123.29, 226.29) vs. 104.67 (77.22, 138.43) and 2.58 (1.96, 3.91) vs. 2.15 (1.67, 2.60) respectively, all P<0.001). PLR was positively correlated with Kerr score (r=0.439, P<0.001), C-reactive protein (r=0.328, P<0.001) and erythrocyte sedimentation rate (r=0.410, P<0.001). NLR also exhibited a positive relationship with Kerr score (r=0.235, P<0.001), C reactive protein (r=0.169, P=0.005) and erythrocyte sedimentation rate (r=0.123, P=0.037). A PLR level of 176.709 was shown to be the best predictive cut-off value for TA disease activity (sensitivity 44.6%, specificity 93.0%, and area under the curve=0.766).A NLR level of 2.128 was shown to be the best predictive cut-off value for TA disease activity (sensitivity 70.9%, specificity 47.7%, and area under the curve=0.691). Conclusion: PLR and NLR are useful markers for predicting disease activity of TA patients.

AB - Objective: To investigate if paclitaxel can enhance the protective effect of myocardial ischemia preconditioning on ischemia/reperfusion injury in aged ratand explore related mechanism. Methods: Primary cardiomyocytes of Sprague-Dawley rats were isolated by trypsin and divided into 5 groups(n=6 each): control group, hypoxia injury group, hypoxia preconditioning group, paclitaxel group,and paclitaxel+hypoxia preconditioning group. The structure of microtubules and the expression of hypoxia-inducible factor-1alpha(HIF-1alpha) were analyzed by immunofluorescence staining. The Langendorff isolated heart perfusion model was applied in 4 groups: hypoxia reperfusion injury group, hypoxia preconditioning group, paclitaxel group, and paclitaxel+hypoxia preconditioning group. Each group was further divided into elderly subgroup and adult subgroup (n=6 each). Left ventricular developed pressure and maximum rate of rise in left ventricular pressure were analyzed. Results: (1) Primary cardiomyocyte experiments showed that the myocardial tubular microtubule structure in control group was intact and evenly stained; most of the microtubules in the hypoxia-injured group were absent and the tubular tissue was broken; the hypoxia-induced damage on microtubule structure was smaller in the hypoxic preconditioning group compared with the hypoxic injury group (microtubule staining was not uniform, and the lattice structure was broken, but not that obvious as in the hypoxia group); the tubular structure of the microtubules of the paclitaxel group was basically complete, and the staining was basically uniform.The integrity of tubular structure was maintained to some extent, similar to a normal microtubule structure in paclitaxel+hypoxia preconditioning group. The expression of HIF-1alpha in the cytoplasm and nucleus was very low in the control group, which was evidenced in both cytoplasm and nucleus in the hypoxic injury group.The expression was further increased in hypoxic preconditioning group, significant nuclear HIF-1 expression was found in the paclitaxel group, the expression was aggregated in the nucleus in the Paclitaxel+ hypoxia preconditioning group. (2)In Langendorff isolated heart perfusion model, left ventricular developed pressure was similar between the elderly subgroup and the adult subgroup at the end of the infusion,after precondition, 5 minutes of reperfusion, 30 minutes of reperfusion, and 60 minutes of reperfusion in the hypoxic injury group (all P> 0.05).In the hypoxic injury group, both the elderly subgroup and the adult subgroup had lower left ventricular developed pressure at 30 minutes of reperfusion when compared with the end of the infusion((15.63+/-4.88) mmHg (1 mmHg=0.133 kPa) vs. (95.63+/ 22.14)mmHg and (17.31+/-2.75)mmHg vs. (91.00+/-9.58)mmHg, respectively,all P<0.05). In the hypoxic preconditioning group, the adult subgroup had higher left ventricular developed pressure at 5 and 30 minutes of reperfusion when compared with the elderly subgroup((7.13+/-1.02) mmHg vs. (3.75+/-1.06)mmHg and (43.94+/ 3.21)mmHg vs.(16.31+/-1.54)mmHg, respectively,all P<0.01). In the paclitaxel group, the adult subgroup had higher left ventricular developed pressure at 30 and 60 minutes of reperfusion when compared with the elderly subgroup((44.31+/ 7.59)mmHg vs. (5.44+/-1.21)mmHg, (51.56+/-6.03)mmHg vs. (22.19+/-5.14)mmHg, respectively, all P<0.01). In the paclitaxel+hypoxia preconditioning group, both the elderly subgroup and the adult subgroup had lower left ventricular developed pressure at 30 minutes of reperfusion when compared with the end of the infusion((18.63+/-4.30)mmHg vs. (99.94+/-8.23) mmHg, P<0.01; (49.69+/-5.34)mmHg vs. (95.31+/-5.26)mmHg, P<0.05). Meanwhile, the adult subgroup had higher left ventricular developed pressure at 30 minutes of reperfusion when compared with the elderly subgroup((49.69+/-5.34)mmHg vs. (18.63+/-4.33)mmHg, P<0.01).The adult subgroup had higher change rate of maximum rate of rise in left ventricular pressure at 60 minutes of reperfusion when compared with the elderly subgroup in hypoxia preconditioning group, paclitaxel group, and paclitaxel combined hypoxia preconditioning group((62.83+/-3.92)% vs. (33.33+/-3.20)%, (44.17+/-2.32)% vs. (36.67+/-2.88)%, (72.50+/-2.66)% vs. (53.17+/-2.56)%, respectively,all P<0.01). Conclusion: Paclitaxel can enhance the myocardial protective effect of myocardial ischemia preconditioning through stabilizing microtubules of cardiomyocytes and promoting HIF-1alpha localization in the nucleus.

PMID- 30293380 TI - [Analysis on the gender-specific risk factors of new-onset cerebral hemorrhage]. AB - Objective: To explore the gender-specific risk factors of new-onset cerebral hemorrhage. Methods: In this prospective cohort study,a total of 98 961 participants((51.1+/-12.6)years old), who underwent the 2006 to 2007 physical examination and met the inclusion criteria, were enrolled from the Kailuanstudy cohort. There were 78 908 (79.7%) male,and 20 053 (20.3%) female.The incidence of cerebral hemorrhage was observed once per year until December 31, 2016.The difference on the incidence of cerebral hemorrhage between male and female was compared. Multivariate Cox regression analysis was applied to analyze therisk factors of cerebral hemorrhage events among different genders. Results: The participants were followed up for(10.00+/-0.73) years,and 860 cerebral hemorrhage events were recorded during follow up. The incidence of cerebral hemorrhage in the population was 86.90/10 million person years (standardized incidence rate of 47.85/10 million person years). The incidence of cerebral hemorrhage was significantly higher in male (49.61/10 million person years) than in female (34.07/10 million person years, P<0.05). Multivariate Cox regression analysis showed that 45-59 years old, >= 60 years old, diabetes,and waist-hip ratio were more strongly related to new-onset of cerebral hemorrhage events in female than in male, and the hazard ratios(95%CI) were 2.33 (1.23-4.43) ,2.71 (1.30-5.66) ,2.16 (1.24-3.74) and 8.79 (1.42-54.32) in female versus 1.55 (1.21-1.97) ,2.16 (1.68-2.78) ,1.19 (0.93-1.53) and 3.21 (1.09-9.41) in male, respectively. The risk of male cerebral hemorrhage increased by 29% (HR=1.29, 95%CI 1.19-1.40) in male and 24% (HR=1.24, 95%CI 1.20-1.28) in female,when the systolic blood pressure increased 10 mmHg (1 mmHg=0.133 kPa). Conclusions: The incidence of cerebral hemorrhage is higher in male than in female in this cohort.The association between systolic blood pressure and cerebral hemorrhage is stronger in male than that in female.The associations between age, waist-hip ratio, diabetes and cerebral hemorrhage are stronger in female than in male.

AB - Persistently high risk human papillomavirus (HPV) infection is one of the indispensable factors of cervical cancer, which is the secondly most common cancer of women in developing countries. Nowadays HPV DNA detection has been more frequently used in cervical cancer initial screening. However, the specificity and sensitivity of HPV DNA detection are low and the triage of HPV positive women is necessary to identify the authentically high-risk population, and avoid the waste of health care resource and excessive treatment. There are different advantages and disadvantages in triage methods including the cytology, HPV DNA genotype, HPV mRNA detection and biological markers such as p16/Ki-67, respectively. Here we briefly describe and evaluate each triage method. PMID- 30293387 TI - [Incidence and mortality of bladder cancer in China, 2014]. AB - Objective: To estimate the incidence and mortality of bladder cancer in China based on the cancer registration data in 2014, collected by the National Central Cancer Registry (NCCR). Methods: There were 449 cancer registries submitted bladder cancer new cases and deaths occurred in 2014 to NCCR. After evaluating the data quality, 339 registries' data were finally accepted for analysis. According to the national population data of 2014, the nationwide incidence and mortality of bladder cancer were estimated by stratification in the area (urban or rural), gender, and age. Chinese population census in 2000 and Segi's population were used for age-standardized incidence/mortality rates. Results: All 339 cancer registries covered a total of 288 243 347 populations (144 061 915 in urban and 144 181 432 in rural areas). The percentage of morphologically verified cases and death certificate-only cases were 74.86% and 1.45%, respectively. The mortality to incidence ratio was 0.41. The estimates of new bladder cancer cases were 78 100 in China in 2014, with a crude incidence rate of 5.71/100 000. The age-standardized incidence rates by China standard population (ASR China) and world standard population (ASR world) of bladder cancer were 3.61/100 000 and 3.56/100 000, respectively. Cumulative incidence rate of bladder cancer in China was 0.41%. The crude and ASR China incidence rates in urban areas were 6.88/100 000 and 4.07/100 000, respectively, whereas those were 4.29/100, 000 and 2.96/100 000 in rural areas. The estimates of bladder cancer deaths caused by bladder cancer were about 32 100 in China in 2014, with a crude mortality rate of 2.35/100 000. The ASR China and ASR world mortality rates were both 1.30/100 000 with a cumulative mortality rate (0-74 years old) of 0.12%. The crude and ASR China mortality rates were 2.79/100 000 and 1.41/100 000 in urban areas, respectively, whereas those were 1.81/100 000 and 1.14/100 000 in rural areas. Conclusions: The incidence and mortality pattern of bladder cancer were different in urban and rural areas. The incidence and mortality were higher in urban areas than that in rural areas, and higher for male than for female. We should focus on strengthening the prevention and control of bladder cancer in key population, especially men in urban areas. PMID- 30293388 TI - [Expression of granulocyte colony-stimulating factor receptor in colitis associated colonic carcinogenesis]. AB - Objective: To investigate the expression of granulocyte-colony stimulating factor receptor (G-CSFR) in a mouse model of colitis-associated cancer (CAC), and the roles of G-CSFR positive immune cells in the development of CAC. Methods: The C57BL/6 mouse model of CAC was established by azoxymethane and dextran sulphate sodium. Three different stages in the development of CAC, including inflammation (AD1), mild dysplasia (AD2) and adenocarcinoma (AD3) were simulated. Colon tissue was digested into single cell suspension and the expressions of G-CSF and G-CSFR were analyzed by real-time PCR and fluorescence activated cell sorter (FACS). The expressions of G-CSFR on T cell, macrophage and neutrophil were analyzed by FACS. Results: The establishment of mouse model can effectively simulate the disease progression of CAC. The results of real-time PCR detection showed that the expression level of G-CSF mRNA in AD1, AD2 and AD3 groups were 1.2, 7.3 and 18.0 fold changes of the control group, respectively. The differences between AD2, AD3 and control groups were statistically significant (P<0.05). G-CSFR mRNA levels in AD1, AD2 and AD3 groups were 1.5, 2.2 and 4.5-fold changes of the control group, respectively. The difference between AD3 and control groups was statistically significant (P<0.05). FACS showed that the percentages of CD45(+) G-CSFR(+) cells in colorectal tissues of the control group, AD1, AD2 and AD3 groups were (21.84+/ 1.77)%, (41.48+/-4.15)%, (44.84+/-8.54)% and (57.76+/-1.95)%, respectively.The percentages of CD45(+) G-CSFR(+) cells in AD2 and AD3 groups were significantly higher than that of control group (P<0.05). The percentages of CD45(+) G-CSFR(+) macrophage in the colorectal tissues of the control group, AD1, AD2 and AD3 groups were (21.54+/-5.88)%, (47.14+/-5.25)%, (42.49+/-7.80)% and (29.25+/ 8.24)%, respectively. The percentages of CD45(+) G-CSFR(+) T cells in these groups were (30.04+/-6.87)%, (29.65+/-8.08)%, (33.75+/-7.37)% and (33.32+/ 9.85)%, respectively. The percentages of CD45(+) G-CSFR(+) granulocyte were (2.39+/-2.10)%, (4.05+/-1.56)%, (3.62+/-2.67)% and (2.26+/-0.85)%, respectively (P<0.05). The percentages of G-CSFR(+) macrophage and G-CSFR(+) T cells were significantly higher than that of G-CSFR(+) granulocyte (P<0.05). The differences between AD1 and control group, AD2 and control group, AD1 and AD2 group, AD2 and AD3 group were statistically significant (P<0.05). Conclusions: The expression of G-CSFR is significantly up-regulated in the development of CAC. The enrichment of G-CSFR(+) macrophages in the colon tissue suggests G-CSFR(+) macrophages participate in the development of CAC. PMID- 30293389 TI - [Effects of FPR2 gene silencing on the proliferation, migration and invasion of human glioma U87 cells]. AB - Objective: To investigate the effects of formyl peptide receptor 2 (FPR2) silencing on the proliferation, migration and invasion of human glioma U87 cells and its possible mechanisms. Methods: The expression of FPR2 was detected in normal glial cells, glioma cells, normal brain tissues and glioma tissues using Western blot and immunohistochemistry staining. A synthesized siRNA duplex was employed to inhibit FPR2 in human glioma cells (U87). The knockdown efficiency was evaluated by real-time reverse transcription-polymerase chain reaction (RT qPCR) and Western blot. MTT, transwell assays and flow cytometry analyses were used to determine the cell proliferation, migration, invasion and apoptotic rates of U87 cells, respectively. Mice xenograft experiments were used to observe the effect of FPR2 silencing on the tumorigenesis of U87 cells in vito. Western blot and enzyme-linked immunosorbent assays were performed to detect the expression and release of cell cycle and migration-related proteins. Results: The expression of FPR2 was significantly higher in glioma cell lines and glioma tissues than that in normal glial cells and brain tissues. Compared with blank control and negative control, FPR2 mRNA and protein levels in siRNA group were significantly downregulated. The cell proliferation inhibitory rates in FPR2 siRNA group were (23.1+/-5.1)%, (39.6+/-5.6)% and (44.4+/-6.7)% at 24 h, 48 h and 72 h, respectively, which were significantly increased than those in negative control group [(3.2+/-0.6)%, (5.7+/-0.8)% and (7.9+/-0.9)%, respectively; P<0.05]. The apoptosis rate in FPR2 siRNA group was (17.4+/-2.1)%, which was significantly elevated than that in the negative control group with (5.4+/-0.5)% and blank control group with (3.8+/-0.3)% (all P<0.05). In addition, the numbers of migrated cells were 108.7+/-9.5 in FPR2 siRNA group, which was significantly lower than that in blank control group 312.9+/-17.5 and negative control group (304.4+/-15.7, all P<0.05). Likewise, the numbers of invaded cells were 19.3+/ 3.2 in FPR2 siRNA group, which was significantly lower than that in blank control group 106.9+/-8.5 and negative control group (102.4+/-7.4, all P<0.05). Moreover, the growth of FPR2 siRNA transfected U87 cells in vivo was remarkably decreased comparing with the negative group (P<0.05). Furthermore, the expression of cyclin D1 and VEGF in FPR2 silencing U87 cells was suppressed mainly through beta catenin signaling pathway. Conclusions: FPR2 silencing by siRNA can inhibit the growth, migration and invasion ability, but promote the apoptosis of U87 cells. The possible mechanisms might be associated with the inhibitory expression of cyclin D1 and VEGF. PMID- 30293390 TI - [Relationship between c-kit mRNA expression and prognosis in patients with rectal carcinoma]. AB - Objective: To investigate the correlation between c-kit mRNA expression and prognosis in patients with rectal carcinoma. Methods: The expression of c-kit mRNA in rectal carcinoma tissues(n=66) was detected by multiplex branched-DNA liquid chip method. According to the expression level, the patients were classified into the c-kit mRNA high expression group and the low group. We analyzed the relationship between the c-kit mRNA expression and the clinicopathological characteristics of patients, as well as the factors affecting patients'prognosis. Results: Of the 66 rectal carcinoma patients, 18(27.3%)cases were c-kit mRNA high expression. No significant correlation was found between the c-kit mRNA expression and gender, age, preoperative carcinoembryonic antigen, preoperative hemoglobin, distance to verge, lymph node metastasis, tumor thrombus, T stage, TNM stage and tumor differentiation (P>0.05). In follow-up, 34 patients died, 32 patients and 36 patients were recurrence or metastasis. The 1-, 3-, 5-year overall survival(OS) of c-kit mRNA high expression group were 100.0%, 77.8%, 77.8%, respectively, while those of the low one were 93.8%, 56.3%, 45.8%, respectively. The difference was statistically significant(P=0.025). Lymph node metastasis, T stage and TNM stage were also significant associated with OS(P<0.05). The 1-, 3-, 5-year disease free rate (DFS)of the c-kit mRNA high expression group were 100.0%, 77.8% and 77.8%, respectively, while those of the low one were 77.1%,43.8% and 41.7%, respectively, and the difference between the two groups was significant (P=0.044). As a reslut, c-kit mRNA expression (P=0.038) and TNM stage (P=0.039) were the independent prognostic factors affecting the OS in rectal cancer patients. Conclusions: Low expression of c-kit was associated with poor prognosis of rectal carcinoma. And the mechanism underlying this phenomenon deserves further exploration. PMID- 30293391 TI - [The value of ultrasound classification in BI-RADS category 4 of breast complex cystic masses]. AB - Objective: To analyze the feature of breast complex cystic masses and to classify it at ultrasonography (US), which applied to the Breast Imaging Reporting and Data System (BI-RADS) categories 4a to 4c with pathological results as the golden standards. Methods: The ultrasonographic data and clinical features of 78 patients with complex cystic masses confirmed by pathology in Cancer Hospital from July 2014 to June 2017 were retrospectively reviewed. The complex cystic breast masses were divided into four classes on the basis of their US features: type 1 [thick wall and (or) thick septa (> 0.5 mm)], type 2 (one or more intra cystic masses), type 3 (mixed cystic and solid components with cystic components more than 50%) and type 4 (mixed cystic and solid components with solid components more than 50%). Positive values (PPVs) were calculated for each type. Multiple linear regression analysis was used to analyze the ultrasonographic features of the masses (lesion size, margins, blood flow resistance index, calcification, and axillary lymph nodes, etc.) with malignant correlation. Results: There were 81 lesions in 78 patients. Among the 81 masses based on US appearance, 14 (17.3%) were classified as type I, 18 (22.2%) as type II, 18 (22.2%) as type III, and 31 (38.3%) as type IV. The positive predictive values of the malignant lesions of type I, type II, III and IV were 7.1%, 16.7%, 61.1% and 48.3%, respectively (P=0.040). In all the 81 masses, 14 were BI-RADS categories 4a, 18 were BI-RADS categories 4b and 49 were BI-RADS categories 4c. Masses with maximum diameter equal to or larger than 2.0 cm, unclear margins, RI>=0.7 and presence of abnormal axillary nodes assessment had a high probability of malignancy (P=0.030, 0.038, <0.001 and 0.025, respectively). Conclusion: Ultrasound typing is helpful for differentiating benign and malignant breast complex cysts and classifying BI-AIDS 4a to 4c, thus providing clearer treatment for clinical practice.

PMID- 30293393 TI - [The association of metastasis-related indexes of lymph nodes and the prognosis of stage N2b colorectal cancer patients]. AB - Objective: To evaluate the prognostic value of lymph node metastasis-related indexes in patients with stage N2b colorectal cancer. Methods: Clinicopathologic data of 245 patients with stage N2b colorectal cancer who initially underwent radical operation in Cancer Hospital, Chinese Academy of Medical Sciences between January 2007 and December 2012 were retrospectively analyzed. The prognostic values of several indexes, including number of positive lymph nodes, number of negative lymph nodes, lymph node ratio (LNR) and log odds of positive lymph nodes (LODDS) were analyzed. Results: The 5-year overall survival rate of 245 patients with colorectal cancer was 54.0%, and the 5-year recurrence-free survival rate was 48.5%.Univariate analysis showed that perineural or blood vessel invasion, T stage, postoperative adjuvant therapy, number of positive lymph nodes, number of negative lymph nodes, LNR, and LODDS were significantly associated with the 5 year overall survival of colorectal cancer patients (P<0.05). Multivariate cox regression analysis showed that, number of positive lymph nodes, number of negative lymph nodes, LNR, LODDS were all independent prognostic factors for stage N2b colorectal cancer patients (P<0.05). The areas under the receiver operating characteristic curve (ROC) curves of number of positive lymph node, number of negative lymph nodes, LNR and LODDS were 0.649, 0.667, 0.690 and 0.683, respectively, however, no statistical significance was observed between the number of negative lymph nodes (P=0.622), LNR (P=0.178) or LODDS (P=0.272) and the number of positive lymph nodes. Conclusion: The number of positive lymph nodes, number of negative lymph nodes, LNR and LODDS were all independent prognostic factors for patients with stage N2b colorectal cancer.

PMID- 30293395 TI - [Analysis of clinicopathological characteristics and prognostic factors of foot and ankle soft tissue and bone tumors]. AB - Objective: To evaluate the clinicopathological characteristics of foot and ankle soft tissue and bone tumor, and to analyze the prognosis and the related factors of malignant tumors in this site. Methods: 74 patients with soft tissue and bone tumors of foot and ankle from January 2006 to February 2017 were retrospectively analyzed. The clinicopathological characteristics, the treatment and survival status of malignant tumors were followed up, and the clinical and therapeutic factors related to prognosis were analyzed. Results: Of the 74 patients, 34 were males and 40 were females. The male to female ratio was 1?1.18; the age ranged from 12 to 64 years and the median age was 42 years. Tumors located in forefoot of 22 cases, 22 in midfoot, 10 in hind foot, 14 in ankle joint and 6 in multiple sites. 14 cases were bone tumors, including 7 benign and 7 malignant, and 60 cases were soft tissue tumors, including 14 benign and 46 malignant. The most common malignant soft tissue tumors were synovial sarcomas (13 cases), and the most common benign soft tissue tumors were hemangiomas (4 cases). 44 cases of malignant tumors underwent surgery were followed up, of which were 7 bone and 37 soft tissue malignant tumors. Limb salvage surgeries were performed in 33 cases and amputation in 11 cases. The median follow-up time was 69.8 months, and the median survival time was 40.7 months. The 1-year, 3-year and 5-year survival rate of soft tissue malignant tumors was 88.0%, 73.0%, and 63.0%, respectively. The 1 year, 3-year and 5-year survival rate of bone malignant tumors was 86.0%, 57.0% and 57.0%, respectively. Univariate analysis showed that the prognostic factors affecting 5-year survival rate were tumor size and adjuvant therapy (P<0.05). Patient's gender, age, tumor location, histological type and surgical procedure had no effect on overall survival(P>0.05). Multivariate analysis showed that tumor size was an independent prognostic factor (RR=7.262, P=0.005). Conclusions: Forefoot and midfoot are more common in foot and ankle soft tissue and bone tumors. Synovial sarcoma is the most common diagnosis in malignant soft tissue tumors, and hemangioma is the most common diagnosis in benign soft tissue tumors. The prognostic factor of malignant soft tissue and bone tumors in foot and ankle is tumor size. Patients with the tumor size of 5 cm or more have a worse prognosis. PMID- 30293396 TI - [Oncological safety and prognosis factors analysis of immediate breast reconstruction after nipple-areola-complex sparing mastectomy]. AB - Objective: To explore the oncological safety of immediate breast reconstruction after nipple-areola complex(NAC) sparing mastectomy(NSM+ IBR) in patients with early stage breast cancer, and to analyze the prognostic factors of NSM+ IBR. Methods: From January 2004 to December 2015, the clinical data of 118 cases of stage I-IIA breast cancer who had undergone NSM+ IBR in Tianjin Tumor Hospital were collected, comparing with 75 cases of I-IIA breast cancer patients who had undergone immediate breast reconstruction after modified radical mastectomy (MRM+ IBR) at the same period. In addition to the prognosis of these two groups, the prognostic factors were also retrospectively analyzed. Results: The median follow up were 53 months in the NSM+ IBR group and 51 months in the MRM+ IBR group, respectively. In the NSM+ IBR group, local recurrence, distant metastasis, death and NAC necrosis occurred in 4, 6, 9 and 4 cases during 3 years after operation, respectively. The local recurrence rate (LRR) was 3.4%, 3-year disease-free survival (DFS) rate was 91.5%, and the overall survival (OS) rate was 92.4%. In the MRM+ IBR group, local recurrence, distant metastasis, and death occurred in 1, 4, and 3 cases during 3 years after operation, respectively. The LRR was 1.3%, 3-year DFS was 93.3%, whereas the OS rate was 96.0%. No statistical difference was noted between the two groups (all P>0.05). That HER-2 positive and molecular type correlated with the 3-year DFS (P<0.05) independently and molecular type correlated with OS (P<0.05) independently in the NSM+ IBR group. Conclusions: NSM does not impair patients' prognosis and could ensure oncological safety of patients with early stage breast cancer. IBR could improve female patients' figure and ensure the quality of life. HER-2 status and molecular type are the independent prognostic factors of the 3-year DFS. Molecular type is the independent prognosis factor of OS.

AB - Objective: To investigate the efficacy and safety of lobaplatin (LBP) plus S-1 for advanced gastric cancer (AGC) and determine the potential role of circulating tumor cells (CTC) for predicting the therapeutic response and prognosis. Methods: From January 2014 to February 2015, 64 consecutive patients with AGC received lobaplatin plus S-1 chemotherapy in Liaocheng People's Hospital. The clinical features, clinical response, adverse effects, prognosis and CTC pre- and post treatment were retrospectively analyzed. The correlation between CTC and patients' disease control rate (DCR), objective response rate (ORR), progression free survival (PFS) as well as overall survival (OS) were investigated. Results: All 64 patients completed 2 cycles of chemotherapy.The number of patients who achieved complete regression, partial regression, stable and progression were 0, 24 (37.5%), 18 (28.1%) and 22 (34.4%), respectively. ORR was 37.5% and DCR was 65.6%. The median PFS was 10.8 months(95%CI 7.1-12.0) and the median OS was 16.1 months(95%CI 12.4-18.8). The ORR and PFS were not significantly different between patients with baseline CTC>=2 and CTC<2 (25.0% vs 53.6%, P=0.150; 6.2 months vs 7.5 months, P=0.780), while the DCR and OS were significantly different (45.9% vs 90.0%, P=0.008; 10.5 months vs 17.2 months, P<0.001). After 2 cycles of chemotherapy, the ORR and DCR in patients with CTC>=2 were 16.7% and 45.9%, respectively, which were significantly lower than those observed in patients with CTC<2 (50.0% and 90.0%, respectively). The former also had shorter median PFS and OS (6.6 months vs 8.9 months, 8.4 months vs 15.0 months, respectively). Patients with persistently CTC<2 or those exhibiting an conversion to CTC<2 following chemotherapy had an improved PFS and OS, while patients with persistently CTC>=2 or those exhibiting an conversion to CTC>=2 following therapy had shorter PFS and OS.The most frequent adverse effects were grade 1 or 2 gastrointestinal discomfort and myelosuppression. No patients discontinued chemotherapy because of adverse events. Conclusions: Lobaplatin plus S-1 had manageable safety profile and promising antitumor activity in patients with AGC. CTC could be used as a biomarker in evaluating therapeutic response and predicting their prognosis. PMID- 30293398 TI - [Chinese expert consensus on the clinical diagnosis and treatment of advanced breast carcinoma(2018)]. AB - Breast cancer is the most common malignant tumor among women in the world. In 2015, there were about 272 000 new diagnosed cases and over 70 000 deaths of breast cancer in China. In new cases of breast cancer each year, about 3 to 10 percent have distant metastases at the time of diagnosis. Among the early-stage patients, 30%-40% will develop into advanced breast cancer. The 5-year survival rate of patients with the advanced breast cancer is only 20%, and the overall median survival is 2-3 years. Although advanced breast cancer is still difficult to cure at present, we can relieve the clinical symptoms, improve the quality of life and further prolong the survival time through development of new drugs and the optimization model of treatment. Patients with advanced breast cancer have their own particularity in the choice of treatment options. Moreover, there is no standard recommendation for the treatment of refractory breast cancer after multiline therapy. In order to offer reference for clinicians, the Chinese expert group has analyzed, summarized and discussed the related research data of diagnosis, treatment and prognosis of inoperable locally advanced breast cancer and recurrent or metastatic breast cancer, and developed the Chinese expert consensus on the clinical diagnosis and treatment of advanced breast carcinoma (2018). PMID- 30293399 TI - [Consensus on clinical diagnosis, treatment and prevention management of chemotherapy induced thrombocytopenia in China(2018)]. AB - Chemotherapy induced thrombocytopenia (CIT) is a common side-effect of chemotherapy in cancer patients, which lead to dose and cycle reduction or chemotherapy delay, or even the need of platelet transfusion. Therefore, CIT significantly increases the cost of treatment, reduces the efficacy of chemotherapy and the quality of life, and shortens the survival time of patients. The main treatments of CIT include transfusion of platelets, recombinant human thrombopoietin (rhTPO), and recombinant human interleukin-11 (rhIL-11). RhIL-11 is the first approved thrombocytopoietic cytokine. Interleukin-11 has been shown to be effective in the treatment of thrombocytopenia. RhTPO is a recombinant full length glycosylated thrombopoietin, which is a ligand for c-Mpl protein. Several observations indicated that administration of rhTPO before and after chemotherapy might be beneficial to patients, which enhances platelet recovery and reduces thrombocytopenia after moderately myelosuppressive regimens. In recent years, the application of rhTPO in CIT treatment has dramatically changed the management and treatment plan of CIT. The China Society of Clinical Oncology (CSCO) published a consensus on CIT in 2014. Based on this, the expert committee updated "Consensus on clinical diagnosis, treatment and prevention management of chemotherapy induced thrombocytopenia in China (2018)" according to the recent literature and clinical research. The new evidence-based practice consensus for CIT aims to provide more reasonable diagnosis, treatment of prevention regimens for CIT patients to maintain the normal platelet counts. PMID- 30293400 TI - Postpartum stretchmarks: repairing activity of an oral Centella asiatica supplementation (Centellicum(r)). AB - BACKGROUND: This registry study evaluates the effects of oral Centellicum(r), a new preparation of Centella asiatica (CA) on cutaneous stretchmarks (SMs) on the lower abdominal wall in comparison with the topical treatment with a specific antistretch cream. This cream is used for pregnancy SMs. The aim of the management was to give back to the structurally damaged skin areas (apparent as SMs) a normal elasticity and resistance and improving the local microcirculation. METHODS: We selected 78 healthy women with SMs at least 6 months postpartum available to follow the registry plan. The subjects were evaluated in three treatment groups: Clarins, stretch mark minimizer, the hydrating control cream and Centellicum(r) 3X225 mg/day for 6 weeks. RESULTS: The three registry groups of otherwise healthy subjects were comparable at inclusion and 6 weeks: 25 women used the SMs cream 1 (mean age 34.4;3.2); 28 control women (age 35.2;2) used the hydrating control cream. The third group (25 women; mean age 35.3;1.5) used the hydrating control cream and oral Centellicum(r) as a supplementary management. Standard management was used in all groups. As for the safety issue, no allergy, no side effects and no tolerability problems were observed. The compliance was very good and there were no drop outs. No other drug or treatment was used during the registry period. Skin thickness (ultrasound, measuring at the edge of at the largest visible stretchmark) increased significantly more at 6 weeks with Centellicum(r) in comparison with both controls (P<0.05). Skin thickness at the center of the SM (skin was less dense at this level) was also increased more with the supplement in comparison with the other managements (P<0.05). The grey scale median improved more (increased) with Centellicum at 6 weeks (P<0.05). The skin included more collagen components and become whiter or denser at ultrasound. Skin perfusion measured by laser Doppler showed a higher improvement with Centellicum(r) (P<0.05). Skin temperature, considered a function of nutritional and thermoregulatory dermal perfusion, improved more with the supplement (P<0.05). Elasticity (measured by elastosonography) was improved more with the supplement (P<0.05). The subjective evaluation with an analogue score resulted better (the SMs were less visible and the score decreased) with Centellicum(r) (P<0.05). The number of visible SMs was decreased more with Centellicum(r) (P<0.05). CONCLUSIONS: Oral supplementation with Centellicum(r) appears to improve SMs in a relatively short period of time. Larger studies are needed to evaluate the protective and repairing potentials of CA. PMID- 30293401 TI - An innovative approach to evaluate preeclampsia risk in the first trimester of pregnancy.

PMID- 30293403 TI - Changes in rectus femoris architecture induced by the reverse nordic hamstring exercises. AB - BACKGROUND: Injuries and mechanical stimuli alter the muscle architecture and, therefore, its function. The changes in the architecture of the Rectus Femoris (RF) induced by an eccentric training protocol with Reverse Nordic Hamstring exercises (RNHE) have never been studied. Therefore, the aim of the present study was to determine the architectural adaptations of the Rectus Femoris (RF) after an eccentric training with Reverse Nordic Hamstring exercises (RNHE), followed by a subsequent detraining period. METHODS: The 26 subjects performed a first week of control, 8 weeks of eccentric training, concluding with a 4-week period of detraining. The architectural characteristics of the RF were evaluated using 2D ultrasound at rest (pretest - week 1), after the training (posttest - week 9), and at the end of the detraining period (retest - week 13). RESULTS: At the end of the training period, a significant increase in the muscle fascicle length (FL) (t=-8.96, d=2.22, P< 0.001), muscle thickness (MT) (t=-8.76, d=2.219, P< 0.001), pennation angle (PA) (t=-9.83, d=2.49, P< 0.05) and cross-sectional area (CSA) (t=- 13.06, d=3.06, P< 0.001) was observed. After the detraining period FL, MT, PA and CSA showed a significant decrease. CONCLUSIONS: The eccentric training with RNHE may cause changes in the architectural conditions of RF, which, in addition, are also reversible after a 4-week detraining period. The adaptations produced by RNHE may have practical implications for injury prevention and rehabilitation programs, which include the changes in muscle architecture variables. PMID- 30293404 TI - Changes in diet, and the relationship between diet and physical activity, within and across the lifetime of current ultra-endurance exercisers. AB - BACKGROUND: There is currently no information on the lifetime diet of ultra endurance exercisers. This study describes changes in diet across the lifetime of current ultra-endurance exercisers and the relationship between diet and physical activity (specifically ultra-endurance exercise [UEE]). METHODS: Lifetime physical activity and diet were assessed in current ultra-endurance exercisers (n=120; ages 21-74 years) over six life periods (5-12, 13-18, 19-30, 31-45, 46 60, 61-75 years). Using the life period having the largest absolute increase in UEE (IUEE), diet was assessed according to food category scores and dietary patterns. Changes in lifetime diet were described by comparing food category scores between adjacent life periods. Differences in food category scores were investigated between the life period for each IUEE group and the preceding life period and associations between dietary patterns and UEE were investigated within each IUEE group. Relationships between lifetime diet and UEE were investigated by examining associations between lifetime food category scores and lifetime UEE. RESULTS: The participant group had significant increases in all food category scores from 13-18 to 19-30 years and significant decreases in all food category scores from 19-30 to 31-45 years. UEE correlated negatively with the Western style dietary pattern in the IUEE19- 30 group and positively with the fruit and vegetable dietary pattern in the IUEE31-45 group. There was a positive correlation between lifetime UEE and lifetime vegetables and fruit category scores. CONCLUSIONS: The ultra-endurance exercisers in this study exhibited changes in diet similar to general populations, which appear to reflect typical nutritional requirements across the lifespan. PMID- 30293405 TI - Therapeutic validity of exercise interventions in the management of fibromyalgia. AB - BACKGROUND: This study aimed (1) to evaluate the therapeutic validity of exercise interventions included in a previous umbrella systematic review of high-quality randomized controlled trials (RCTs) in the management of fibromyalgia; and (2) to explore whether exercise interventions with high therapeutic validity and that meet the 2013 American College of Sports Medicine (ACSM) guidelines are positively associated with greater pain relief. METHODS: Therapeutic validity was evaluated based on the CONsensus on Therapeutic Exercise and Training (CONTENT) scale, in high methodological quality RCTs found in the nine systematic reviews of a previous umbrella review on exercise interventions in the management of fibromyalgia. Additionally, the compliance of the 2013 ACSM exercise recommendations for fibromyalgia was analyzed. The effect size for pain relief after the exercise programs was also considered. RESULTS: The CONTENT mean total score was 4.42 out of 9, demonstrating generally low therapeutic validity of the 28 included RCTs. There was poor concordance between therapeutic validity and pain relief (Kappa values ranging between -0.6 to 0.57). Kappa statistic results showed poor concordance (k=0.01) between statistically significant (p<0.05) pain relief values and achievement of 2013 ACSM exercise recommendations. CONCLUSIONS: The therapeutic validity of exercise intervention programs in fibromyalgia is low. This is mainly due to incomplete descriptions of exercise interventions and adherence. Poor concordance is found between high therapeutic validity and accomplishment of the ACSM exercise recommendations with pain relief. Improved standardized reporting is recommended to identify optimal exercise prescription for fibromyalgia. PMID- 30293406 TI - Effects of a home based exercise rehabilitation program for cancer survivors. AB - BACKGROUND: Aerobic and resistance exercises have been promoted recently to improve quality of life in cancer patients. Most cancer survivorship rehabilitation programs consists of supervised exercise programs; however, less data is available on the effects of unsupervised or home-based exercise interventions. The study aimed to compare the physical and physiologic changes in a group of cancer survivors (CS) and a control group of non-cancer, health controls (HC) who participated in individualized home-based aerobic and resistance exercises for 12 months. METHODS: Thirty-three surviving cancer survivors (CS) aged 55.6+/-3 y were enrolled for 1 year of unsupervised exercise prescription programs. Anthropometric parameters hydration status, fitness, and echocardiographic examination were measured every six month and compared to10 HC (aged 52.6 +/- 7.7 y) individuals prior to starting the program (t0) and at 6 (t6) and 12 (t12) months. RESULTS: Among the CS subjects a significant reductions in waist circumference t0: 97.5 +/-15.2; t6: 86.6 +/-13.5; t12: 85.8 +/- 13.9, p<0.05; body cell mass% t0: 50.9+/-4.7; t6: 52.3+/-4.4; t12: 53.7+/-3.7; p<0.05 and extracellular mass %, t0: 49.1+/-4.7 t6; 47.6+/-4.4, t12: 46.2+/-3.7, p < 0.05, were observed as well significant improvements in lower body muscle strength (chair test t0:13.3+/-4.1, t6: 14.2+/-3.5, t12: 15.1+/-3.2; p<0.05). Changes in functionality and heart function were similar between CS and HC's. CONCLUSIONS: Individually prescribed home-based exercise programs were cost effective, safe and resulted in modest improvements in body composition, strength, and total body water distribution with little to no adverse effect on cardiac function. PMID- 30293407 TI - Nutrition, hydration and ergogenic aids strategies in ultraendurance mountain events. AB - BACKGROUND: The purpose of the present research was to analyze nutrition, hydration and ergogenic aids strategies in ultraendurance mountain events. METHODS: A total of 386 ultra endurance mountain races finishers were analyzed. They were divided into three groups according to their race distance: G1: distance less than 45 km (n: 250); G2 distances between 45 and 90 km (n: 71); G3 distances longer than 90 km (n: 65). The ergogenic, nutritional and hydration strategies were quantified after each race by a questionnaire. RESULTS: We found a higher ingestion of (0.56 +/- 0.95), caffeine (G3 M+/-SD; 203.8+/-211.5 mg), water (G3 M+/-SD; 7.1+/-3.7 l) and Portion of Sandwich (nutrition 5.3+/-7.4) NSAID in longer distance probes. Higher performance runners in low and medium distances consumed a significantly (p>0.05) lower quantity of gels (higher 0.76+/ 0.98 vs lower 1.38+/-1.38), and muesli bar (higher 1.09+/-1.13 vs lower 2.04+/ 1.94), and in long distances. Higher performance consumed more water (M+/-SD; higher 8.23+/-3.92 vs lower 6.12+/-3.28) than lower performance ones. They also could maintain a higher rated of perceived exertion than lower performance (G3 M+/-SD; higher 16.7+/-2.28 vs lower 18.2+/-1.71). CONCLUSIONS: Higher distance presented higher nutritional, caffeine and NSAIDs ingestion than lower distances, also, higher performance athletes of higher distance presenter higher water and nutritional ingestion than lower performance ones. In Lower distance probes, higher performance athletes presented lower hydration and nutritional ingestion than lower performance athletes. PMID- 30293408 TI - Bench press performance during an intermittent hypoxic resistance training to muscle failure. AB - BACKGROUND: Resistance training performed under hypoxia conditions has been shown to cause major metabolic and hormonal responses. However, the influence of hypoxia on an acute session has been barely studied. The aim of this study was to evaluate the acute effects of an intermittent hypoxic resistance training (IHRT) to muscle failure on bench press performance. METHODS: A randomized crossover design was performed, and 25 untrained men performed a resistance training under two different conditions: normoxia (FIO2=21%) and high-level hypoxia (FIO2=13%). Resistance training consisted of 3 sets of 75% 1RM to muscle failure, with a 2 minute rest between sets. Physical performance were assessed by quantifying total repetitions, concentric velocity and power variable during all sets. Arterial oxygen saturation, heart rate, rating of perceived exertion (RPE), capillary blood lactate and muscle soreness were also assessed after training. RESULTS: Physical performance during bench press did not differ under hypoxic conditions (p>0.05). However, there were significant increases (p<0.05) of RPE (from 7.5 +/- 0.8 to 7.9 +/- 0.8) and blood lactate concentrations (from 5.5 +/- 1.2 to 6.2 +/- 1.5 mmol/L) in the hypoxia group. CONCLUSIONS: These findings suggest that hypoxic resistance exercise does not affect exercise performance during bench press exercise. However, influence to perceived exercise intensity and blood lactate concentrations, suggesting that hypoxic resistance training may add substantially to the training dose experienced. PMID- 30293409 TI - Pre-cancer diagnosis cardiorespiratory fitness, physical activity and cancer mortality in men. AB - BACKGROUND: The preventive role of pre-cancer diagnosis cardiorespiratory fitness (CRF) and physical activity (PA) in cancer mortality is poorly characterized. AIM: To assess the association between CRF, PA at pre-cancer-diagnosis and cancer mortality in men who diagnosed with cancer later in life. METHODS: A total of 699 men (63+/-10 years) who were diagnosed with cancer during 7.5+/-4.9 years from a baseline treadmill exercise test and reported PA were analyzed. Multivariate Cox models for CRF and univariate model for PA were conducted. Population Attributable Risks (PARs%) and Exposure Impact Number (EIN) of low CRF (<5 METs) and inactivity were determined. RESULTS: During 6.5+/-5.2 years from cancer diagnosis, 56% died from cancer. CRF was inversely, graded and independently associated with cancer death. A 1-MET increase and categories of moderate and high CRF were associated with 7%, 28% and 51% reductions in risk of cancer death, respectively. Active compared to inactive individuals had a 23% reduced risk of cancer mortality [HR=0.77, 95% CI (0.63-0.94), p=0.01]. PARs% of low CRF and inactivity were 4.8% and 9.4%, respectively, while the respective EIN were 3 and 9. CONCLUSIONS: Higher CRF and being active at pre-cancer-diagnosis were associated with lower cancer mortality and longer survival time in men who developed cancer later in life. Screening and intervening for low CRF and inactivity as risk factors during middle-age and maintaining at least moderate CRF and activity levels may be effective strategies for prevention of cancer mortality. PMID- 30293410 TI - The provision of simple written material does not significantly improve physical activity rates in a population with musculoskeletal problems, a double-blinded randomised controlled trial. AB - BACKGROUND: Physical activity has been shown to have significant health benefits to individuals, being effective in the treatment and prevention of multiple different conditions. However, despite these benefits, rates of physical activity remain low in the western world and less than 40% of people in the UK meet physical activity recommendations. Musculoskeletal pain can be a barrier to activity, and patients with pain can stop all activity out of fear of harm. This project seeks to see if simple written advice can influence activity rates and behaviours. METHODS: A double-blinded randomised controlled trial was conducted to assess any impact of simple written material on physical activity rates in patients attending a single UK National Health Service (NHS) Sports Medicine Department. 546 consecutive patients with a range of musculoskeletal problems were randomised to either an "intervention group" (n=235) or "control group" (n=311). Patients in the intervention group received simple written material encouraging of the benefits of physical activity for general aspects of health, including practical steps to increase regular activity in daily life such as commuting, and work. RESULTS: No significant difference in activity rates were seen between the members of the two groups in any of the outcome measures used. These measures included the short-form/7-day recall version of the International Physical Activity Questionnaire (IPAQ), the General Practitioner Physical Activity Questionnaire (GPPAQ), and the "Vital Signs" questions. There were no differences seen in transport choices. Overall physical activity levels were low among both groups, with only one-third reaching national targets of 150minutes of moderate-level physical activity per week, and one in five patients undertaking no regular physical activity. CONCLUSIONS: The provision of simple written material does not significantly improve physical activity rates in patients referred to this NHS Sports Medicine Clinic in the UK. Consideration must be given to more tailored and individualised approached to physical activity promotion. PMID- 30293411 TI - Extracorporeal shock wave therapy for isokinetic muscle strength around the knee joint in athletes with patellar tendinopathy. AB - BACKGROUND: The aim of this study was to explore the efficacy of 16 weeks of extracorporeal shockwave therapy in athletes with patellar tendinopathy. METHODS: Athletes with patellar tendinopathy were matched for age, height and body weight and assigned to the experimental group (n=26) or control group (n=25). Subjects in the experimental group received 16 rounds (once per week) of extracorporeal shockwave therapy (2,000 single shocks; strength, 1.5 to 3.0 bar; shock frequency, 9 to 12 Hz). Subjects in the control group received physical treatments, such as acupuncture, ultrasonic wave, and microwave therapy. RESULTS: After 16 weeks, VAS score in the experimental group was reduced by 69.4% (P<0.01) compared with that at 0 weeks. Knee joint 60 degrees /s and 240 degrees /s peak torques were increased by 17.2% (P<0.01) and 7.2% (P<0.05), respectively, and extensor endurance by 17.4% (P<0.05). VAS score in the control group was reduced by 16.9% (P<0.01) at 16 weeks compared with 0 weeks, and the knee joint 60 degrees /s peak torque was increased by 8.2% (P<0.05). For between-groups comparisons, the VAS score in the experimental group was reduced by 62.7% (P<0.01); whereas knee joint 60 degrees /s and 240 degrees /s peak torques increased by 8.8% and 5.8%, respectively, and extensor endurance by 12.5% (P<0.05). There were no significant differences between male and female subjects (P>0.05). CONCLUSIONS: Extracorporeal shock wave therapy has a positive effect on patellar tendinopathy in athletes, with no gender differences in therapeutic effect. Extracorporeal shock wave therapy may be used to alleviate pain and improve knee joint extensor strength and endurance. PMID- 30293412 TI - Injury patterns in professional motorbike racing: a retrospective analysis of 728 falls. AB - BACKGROUND: In professional motorbike racing falls with high velocities are common. Nonetheless, severe injuries or deaths are rare when compared to regular road traffic. METHOD: In this study, falls in all courses of the largest German race series IDM*Superbike between 2007 and 2013 were analyzed regarding injury patterns and hospital admissions. All races were accompanied by a medical team, including at least one physician who assessed every patient. RESULTS: 728 falls were included. A specific fall mechanism could be determined in 45.5% of the cases. 40.5% were admitted to a trauma center for further diagnostics. A definitive diagnosis was found in 45.4%. In most cases (29.9%) the injury pattern was a fracture of the extremities. In collisions a significantly higher odds ratio of 2.52 (p=0.0001) and in indeterminate falls a significantly lower odds ratio of 0.47 (p<0.0001) was observed. CONCLUSIONS: Fall patterns in professional motorbike racing do not significantly correlate with the severity of the injury. Thus, as in regular patient evaluation, each patient has to be examined thoroughly to avoid misinterpretation. PMID- 30293413 TI - Radiofrequency hemorrhoidectomy: less is less? Results of a comparative study. AB - BACKGROUND: Radiofrequency has been introduced as an instrument conceived to upgrade the conventional treatment of hemorrhoidectomy. To reduce the economic aspect, recently has been introduced a new radiofrequency device: VojantTM. Aim was to compare clinical outcomes of hemorrhoidectomy with LigaSureTM and VojantTM, performed with the Milligan- Morgan technique, in medium-term perspective. METHODS: Between January 2016 and December 2016, 50 consecutive patients with symptomatic grade III and IV were scheduled for surgical treatment. Patients were assigned randomly to undergo either VojantTM or LigaSureTM haemorrhoidectomy. All preoperative and postoperative data were collected. RESULTS: Patients in the LigaSureTM group experienced less pain than those treated by VojantTM, (p<0.05). In VojantTM group one patient developed immediate postoperative bleeding (within 48 h), the other one seven days after surgery. Complete wound healing and return to work activities was faster in LigasureTM group (p<0.05). One stenosis in LigasureTM group and two cases in VojantTM group were detected (p>0.05). CONCLUSIONS: Radiofrequency hemorrhoidectomy with VojantTM seems a valid alternative to Ligasure hemorrhoidectomy. PMID- 30293414 TI - Negative payoffs of upper gastrointestinal endoscopy in patients admitted under observation status. AB - BACKGROUND: More than 70 million americans (23% of the US population) have non cardiac chest pain at least once in their lifetime with gastroesophageal reflux disease (GERD) being the leading cause (37-66%). Current guidelines support the use of a proton pump inhibitor (PPI) prior to invasive or noninvasive testing as a diagnostic, therapeutic and cost effective method as a part of High Value Care recommendations. METHODS: We performed a chart review of 126 patients admitted to the hospital under observation status who underwent upper GI endoscopies in the hospital at 3 different urban community hospitals. This was compared with 260 patients admitted who didn't have this procedure done. We calculated the healthcare burden including length of stay, reimbursement and complications from the procedures/extra stay in the hospital. RESULTS: The direct cost per case was almost two times in the group that underwent the procedure as compared to the group that did not. The mean LOS was higher in the group that underwent the endoscopies. There were no complications and there was no difference in mortality. CONCLUSIONS: Upper gastrointestinal endoscopy in patients with atypical chest pain of GI origin as an initial step is a significant healthcare burden and contradicts the currently recommended High Value Care recommendations. Our study delineates this large negative financial impact when performing upper endoscopies under observation status. Such patients should be started on an empirical trial of PPI, and endoscopy should be reserved for patients whose symptoms are unresponsive to PPIs or have alarm features. PMID- 30293415 TI - Symptoms and dietary practices of irritable bowel syndrome patients compared to controls: results of a United States National survey. AB - BACKGROUND: Little is known regarding the dietary behaviors and epidemiology of irritable bowel syndrome (IBS) patients in the United States (US). METHODS: This was an IRB-approved cross-sectional survey conducted via a secured online server (SurveyMonkey(r)). A representative sample of the US population were queried regarding demographics, gastrointestinal (GI) symptoms, treatments and dietary practices. Of 1,718 respondents, 161 reported IBS. These were compared to 1,116 subjects reporting no GI diagnosis (controls). RESULTS: Overall, 9% reported a diagnosis of IBS. When compared to controls, IBS patients were more likely over 45 years (p<0.001) and female (p<0.001). IBS patients more frequently noted abdominal pain, constipation, diarrhea, gas/bloating and GERD/heartburn (all p<0.001) than controls. Regarding therapeutic measures, IBS patients were more likely to cite food avoidance, over-the-counter remedies, probiotics, consultation with doctor/dietitian, and prescriptions (all p<0.001). However, they were less likely to believe their strategies were effective. While the majority of subjects believed food contributed to their symptoms, those with IBS listed more dietary triggers. IBS patients were more likely to follow a dietary 'plan' with 21% citing lactose-free, 17% gluten-free and 9% low-FODMAP (all p<0.001). Nevertheless, 47% with IBS denied following any dietary plans. A minority, (24%), of IBS patients was aware of the low- FODMAP diet. CONCLUSIONS: In this US survey, IBS was reported by 9% of the population, most often females over 45 years. IBS patients were more likely to implement therapeutic strategies and cite food triggers, yet few were aware of the low-FODMAP diet. Outreach programs could improve awareness of this substantiated intervention. PMID- 30293416 TI - Diverticulosis today. AB - The incidence of diverticulosis and diverticular disease of the colon is increasing worldwide. Although the majority of patients remains asymptomatic long life, the prevalence of diverticular disease of the colon, including acute diverticulitis, is substantial and is becoming a significant burden on National Health Systems in terms of direct and indirect costs. Fiber, non-absorbable antibiotics and probiotics seem to be effective in treating symptomatic and uncomplicated patients, and 5-aminosalicylic acid might help prevent acute diverticulitis. Unfortunately, robust evidence on the effectiveness of a medical strategy to prevent acute diverticulitis recurrence is still lacking. Focus is now being drawn on identifying a new endoscopic classification of the disease to evaluate the correct therapeutic approach by testing various treatments. PMID- 30293417 TI - Prevalence of Helicobacter pylori infection among dyspeptic patients with and without type 2 diabetes mellitus in South-West and South-South regions of Nigeria. AB - BACKGROUND: This multicenter study was undertaken to determine the prevalence of Helicobacter pylori (H. pylori) infection among dyspeptic patients with and without type 2 diabetes mellitus (T2DM). METHODS: Patients with dyspepsia were recruited from tertiary teaching hospitals, three in the South-West and one in the South-South regions of Nigeria, between November 2016 and August 2017. The participants had breath samples analyzed for H. pylori by the Urea Breath Test (UBT) following manufacturer's instructions. Dyspeptic patients who were diagnosed previously with T2DM were recorded. Crosstab using chi-square and correlation analyses were used to test (hypothesis) variables. RESULTS: The entire cohort included 471 dyspeptics, 19 (4%) of whom had T2DM. H. pylori infection was reported in 232/471 (49.3%) dyspeptics and 13/19 T2DM patients, without significant difference between diabetics and nondiabetics. The majority (84.6%) of those positive for UBT and T2DM were in the age group 52-71 years, while none was in the age group 72-91 years. There was no statistical significance (p>0.05) between the age group, UBT and T2DM positive. CONCLUSIONS: Our study showed that, in Nigeria, there is no difference in prevalence of H. pylori in dyspeptic patients with and without T2DM.

AB - The spatial arrangement of target and probe molecules on the biosensor is a key aspect of the biointerface structure that ultimately determines the properties of interfacial molecular recognition and the performance of the biosensor. However, the spatial patterns of single molecules on practical biosensors have been unknown, making it difficult to rationally engineer biosensors. Here, we have used high-resolution atomic force microscopy to map closely spaced individual probes as well as discrete hybridization events on a functioning electrochemical DNA sensor surface. We also applied spatial statistical methods to characterize the spatial patterns at the single molecule level. We observed the emergence of heterogeneous spatiotemporal patterns of surface hybridization of hairpin probes. The clustering of target capture suggests that hybridization may be enhanced by proximity of probes and targets that are about 10 nm away. The unexpected enhancement was rationalized by the complex interplay between the nanoscale spatial organization of probe molecules, the conformational changes of the probe molecules, and target binding. Such molecular level knowledge may allow one to tailor the spatial patterns of the biosensor surfaces to improve the sensitivity and reproducibility.

A major problem with this approach is that other species such as nanoparticles or radical scavenging chemicals can often interfere with these reactions. The results measured in the presence of nanomaterials and scavengers therefore cannot correctly indicate the true dose based on the calibrated results obtained in solutions free of the interfering species. Storing these molecular probes in nanoreactors can overcome this problem. Here we demonstrate for the first time that it is possible to place common probe molecules inside spherical mesoporous silica shells and seal the pores after impregnation for the purpose of using the so-formed nanoreactors as X-ray dose probes. The reactions are isolated from the external environment, while the sealed shells still allow X-rays to freely penetrate through the walls of the nanoreactors. These nanoreactor probes can therefore fiducially report the dose of X-rays, whether the nanoreactors are in solutions, in dry form, or in the presence of scavengers and catalysts in solution.

AB - Evidence that plants can respond to volatile organic compounds (VOCs) was first presented 35 years ago. Since then, over 40 VOCs have been found to induce plant responses. These include VOCs that are produced not only by plants but also by microbes and insects. Here, we summarize what is known about how these VOCs are produced and how plants detect and respond to them. In doing so, we highlight notable observations we believe are worth greater consideration. For example, the VOCs that induce plant responses appear to have little in common. They are derived from many different biosynthetic pathways and have few distinguishing chemical or structural features. Likewise, plants appear to use several mechanisms to detect VOCs rather than a single dedicated "olfactory" system. Considering these observations, we advocate for more discovery-oriented experiments and propose that future research take a fresh look at the ways plants detect and respond to VOCs. PMID- 30293421 TI - Only Para-Hydrogen Spectroscopy (OPSY) Revisited: In-Phase Spectra for Chemical Analysis and Imaging. AB - We revisited only para-hydrogen spectroscopy (OPSY) for the analysis of para hydrogen-enhanced NMR spectra at high magnetic fields. We found that the sign of the gradients and interpulse delays are pivotal for the performance of the sequence: the variant of double-quantum filter OPSY, where the second time interval is twice as long as the first one (OPSYd-12) converts the antiphase spectrum to in-phase and efficiently suppresses the background signal in a single scan better than the other variants. OPSYd-12 strongly facilitates the analysis of para-hydrogen-derived NMR spectra in homogeneous and inhomogeneous magnetic fields. Furthermore, the net magnetization produced is essential for subsequent applications such as imaging, e.g., in a reaction chamber or in vivo. PMID- 30293422 TI - Comprehensive Molecular Characterization of Atmospheric Brown Carbon by High Resolution Mass Spectrometry with Electrospray and Atmospheric Pressure Photoionization. AB - Light-absorbing components of atmospheric organic aerosols, which are collectively termed "brown carbon" (BrC), are ubiquitous in the atmosphere. They affect absorption of solar radiation by aerosols in the atmosphere and human health as some of them have been identified as potential toxins. Understanding the sources, formation, atmospheric evolution, and environmental effects of BrC requires molecular identification and characterization of light-absorption properties of BrC chromophores. Identification of BrC components is challenging due to the complexity of atmospheric aerosols. In this study, we employ two complementary ionization techniques, atmospheric pressure photo ionization (APPI) and electrospray ionization (ESI), to obtain broad coverage of both polar and nonpolar BrC components using high-resolution mass spectrometry (HRMS). These techniques are combined with chromatographic separation of BrC compounds with high performance liquid chromatography (HPLC), characterization of their light absorption with a photodiode array (PDA) detector, and chemical composition with HRMS. We demonstrate that this approach enables more comprehensive characterization of BrC in biomass burning organic aerosols (BBOAs) emitted from test burns of sage brush biofuel. In particular, we found that nonpolar BrC chromophores such as PAHs are only detected using positive mode APPI. Meanwhile, negative mode ESI results in detection of polar compounds such as nitroaromatics, aromatic acids, and phenols. For the BrC material examined in this study, over 40% of the solvent-extractable BrC light absorption is attributed to water insoluble, nonpolar to semipolar compounds such as PAHs and their derivatives, which require APPI for their identification. In contrast, the polar, water soluble BrC compounds, which are detected in ESI, account for less than 30% of light absorption by BrC. PMID- 30293423 TI - Hyporheic Exchange Controls Fate of Trace Organic Compounds in an Urban Stream. AB - First-order half-lives for 26 trace organic compounds (TrOCs) were determined in the hyporheic zone (HZ) and along a 3 km reach of a first-order stream in South Australia during both dry and wet seasons. Two salt tracer experiments were conducted and evaluated using a transient storage model to characterize seasonal differences in stream residence time and transient storage. Lagrangian and time integrated surface water sampling were conducted to calculate half-lives in the surface water. Half-lives in the HZ were calculated using porewater samples obtained from a modified mini-point sampler and hyporheic residence times measured via active heat-pulse sensing. Half of the investigated TrOCs (e.g., oxazepam, olmesartan, candesartan) were not significantly removed along both the investigated river stretch and the sampled hyporheic flow paths. The remaining TrOCs (e.g., metformin, guanylurea, valsartan) were found to be significantly removed in the HZ and along the river stretch with relative removals in the HZ correlating to reach-scale relative removals. Using the modeled transport parameters, it was estimated that wet season reach-scale removal of TrOCs was predominately caused by removal in the HZ when the intensity of hyporheic exchange was also higher. Factors that increase HZ exchange are thus likely to promote in-stream reactivity of TrOCs. PMID- 30293424 TI - A Correlated Series of Au/Ag Nanoclusters Revealing the Evolutionary Patterns of Asymmetric Ag Doping. AB - Doping of metal nanoclusters is an effective strategy for tailoring their functionalities for specific applications. To gain fundamental insight into the doping mechanism, it is of critical importance to have access to a series of correlated bimetal nanoclusters with different doping levels and further reveal the successive transformations. Herein, we report asymmetric doping of Ag into an Au21 nanocluster to form a series of new Au/Ag bimetal nanoclusters and the effects of doping on the evolution of size, structure, and properties based upon X-ray crystallography and optical spectroscopy analyses. The asymmetric doping discovered in the series reveals two important rules. First, the heteroatom doping-induced kernel transformation mechanism is revealed, explaining the successive conversions from Au21(S-Adm)15 with an incomplete cuboctahedral kernel to Au20Ag1(S-Adm)15 with a complete cuboctahedral Au12Ag1 kernel and then to Au19Ag4(S-Adm)15 with an icosahedral Au10Ag3 kernel. The electron density accumulated on the central Au atom(s) is rationalized to force an expansion of radial metal-metal bond angles, which triggers the cuboctahedral-to-icosahedral kernel conversion. This mechanism is generalized by elucidating several other cases. Second, through comparison of a series of seven nanoclusters (all protected by adamantanethiolate), we find that the unit cell symmetry of their crystals is correlated with the symmetry of the cluster's kernel. Specifically, we observe a sequential change from triclinic to monoclinic to trigonal unit cell in the series with increasing kernel symmetry. The kernel structure-dependent optical properties are also discussed. PMID- 30293425 TI - Low-Temperature Oxidation of Ethylene by Ozone in a Jet-Stirred Reactor. AB - Ethylene oxidation initiated by ozone addition (ozonolysis) is carried out in a jet-stirred reactor from 300 to 1000 K to explore the kinetic pathways relevant to low-temperature oxidation. The temperature dependencies of species' mole fractions are quantified using molecular-beam mass spectrometry with electron ionization and single-photon ionization employing tunable synchrotron-generated vacuum-ultraviolet radiation. Upon ozone addition, significant ethylene oxidation is found in the low-temperature regime from 300 to 600 K. Here, we provide new insights into the ethylene ozonolysis reaction network via identification and quantification of previously elusive intermediates by combining experimental photoionization energy scans and ab initio threshold energy calculations for isomer identification. Specifically, the C2H4 + O3 adduct C2H4O3 is identified as a keto-hydroperoxide (hydroperoxy-acetaldehyde, HOOCH2CHO) based on the calculated and experimentally observed ionization energy of 9.80 (+/-0.05) eV. Quantification using a photoionization cross-section of 5 Mb at 10.5 eV results in 5 ppm at atmospheric conditions, which decreases monotonically with temperature until 550 K. Other hydroperoxide species that contribute in larger amounts to the low-temperature oxidation of C2H4, like H2O2, CH3OOH, and C2H5OOH, are identified and their temperature-dependent mole fractions are reported. The experimental evidence for additional oxygenated species such as methanol, ketene, acetaldehyde, and hydroxy-acetaldehyde suggest multiple active oxidation routes. This experimental investigation closes the gap between ozonolysis at atmospheric and elevated temperature conditions and provides a database for future modeling.

AB - Here we introduce for the first time a metal-free trianglamine-based supramolecular organic framework, T-SOF-1, with permanent intrinsic porosity and high affinity to CO2. The capability of tuning the pore aperture dimensions is also demonstrated by molecular guest encapsulation to afford excellent CO2/CH4 separation for natural gas upgrading. PMID- 30293427 TI - Exciton-Phonon Interactions Govern Charge-Transfer-State Dynamics in CdSe/CdTe Two-Dimensional Colloidal Heterostructures. AB - CdSe/CdTe core-crown type-II nanoplatelet heterostructures are two-dimensional semiconductors that have attracted interest for use in light-emitting technologies due to their ease of fabrication, outstanding emission yields, and tunable properties. Despite this, the exciton dynamics of these complex materials, and in particular how they are influenced by phonons, is not yet well understood. Here, we use a combination of femtosecond vibrational spectroscopy, temperature-resolved photoluminescence (PL), and temperature-dependent structural measurements to investigate CdSe/CdTe nanoplatelets with a thickness of four monolayers. We show that charge-transfer (CT) excitons across the CdSe/CdTe interface are formed on two distinct time scales: initially from an ultrafast (~70 fs) electron transfer and then on longer time scales (~5 ps) from the diffusion of domain excitons to the interface. We find that the CT excitons are influenced by an interfacial phonon mode at ~120 cm-1, which localizes them to the interface. Using low-temperature PL spectroscopy we reveal that this same phonon mode is the dominant mechanism in broadening the CT PL. On cooling to 4 K, the total PL quantum yield reaches close to unity, with an ~85% contribution from CT emission and the remainder from an emissive sub-band-gap state. At room temperature, incomplete diffusion of domain excitons to the interface and scattering between CT excitons and phonons limit the PL quantum yield to ~50%. Our results provide a detailed picture of the nature of exciton-phonon interactions at the interfaces of 2D heterostructures and explain both the broad shape of the CT PL spectrum and the origin of PL quantum yield losses. Furthermore, they suggest that to maximize the PL quantum yield both improved engineering of the interfacial crystal structure and diffusion of domain excitons to the interface, e.g., by altering the relative core/crown size, are required. PMID- 30293429 TI - Topological Characterization of Rigid-Nonrigid Transition across the Frenkel Line. AB - The dynamics of supercritical fluids, a state of matter beyond the gas-liquid critical point, changes from diffusive to oscillatory motions at high pressure. This transition is believed to occur across a locus of thermodynamic states called the Frenkel line. The Frenkel line has been extensively investigated from the viewpoint of the dynamics, but its structural meaning is still not well understood. This Letter interprets the mesoscopic picture of the Frenkel line entirely based on a topological and geometrical framework. This discovery makes it possible to understand the mechanism of rigid-nonrigid transition based not on the dynamics of individual atoms but on their instantaneous configurations. The topological classification method reveals that the percolation of solid-like structures occurs above the rigid-nonrigid crossover densities. PMID- 30293428 TI - In-Search Assignment of Monoisotopic Peaks Improves the Identification of Cross Linked Peptides. AB - Cross-linking/mass spectrometry has undergone a maturation process akin to standard proteomics by adapting key methods such as false discovery rate control and quantification. A poorly evaluated search setting in proteomics is the consideration of multiple (lighter) alternative values for the monoisotopic precursor mass to compensate for possible misassignments of the monoisotopic peak. Here, we show that monoisotopic peak assignment is a major weakness of current data handling approaches in cross-linking. Cross-linked peptides often have high precursor masses, which reduces the presence of the monoisotopic peak in the isotope envelope. Paired with generally low peak intensity, this generates a challenge that may not be completely solvable by precursor mass assignment routines. We therefore took an alternative route by '"in-search assignment of the monoisotopic peak" in the cross-link database search tool Xi (Xi-MPA), which considers multiple precursor masses during database search. We compare and evaluate the performance of established preprocessing workflows that partly correct the monoisotopic peak and Xi-MPA on three publicly available data sets. Xi-MPA always delivered the highest number of identifications with ~2 to 4-fold increase of PSMs without compromising identification accuracy as determined by FDR estimation and comparison to crystallographic models. PMID- 30293430 TI - Influence of the SPR Experimental Conditions on the G-Quadruplex DNA Recognition by Porphyrin Derivatives. AB - Surface plasmon resonance (SPR) is a powerful technique to study the interactions of ligands with analytes and therefore a number of biosensor surfaces and injection methods have been developed so far. However, many experimental parameters can affect the interactions and consequently the affinity measurements. In particular, the interactions of positively charged analytes (often used for anionic nucleic acids targets) can be influenced by the sensing surfaces (e.g., negatively charged), leading to significant nonspecific interactions as well as regeneration problems. The aim of the present work is to investigate the effect of different parameters, including ionic strength, SPR biosensor (i.e., nature of the surfaces), and the injection method on the recognition of porphyrin G-quadruplex ligands. We demonstrate that the injection method does not influence the affinity whereas the ionic strength and the nature of the surface impact the recognition properties of the porphyrin for the G quadruplex DNA. We also found that self-assembled monolayer coating surface presents many advantages in comparison with carboxymethylated dextran surface for SPR studies of G-quadruplex DNA/ligand interactions: (i) the electrostatic interaction with charged analytes is less important, (ii) its structure/composition is less sensitive to the ionic concentration and less prone to unspecific adsorption, (iii) it is easily homemade, and (iv) the cost is approximately 10 times cheaper. PMID- 30293431 TI - Polyelectrolyte Composite Membranes Containing Electrospun Ion-Exchange Nanofibers: Effect of Nanofiber Surface Charges on Ionic Transport. AB - Poly(vinyl alcohol) (PVA)-based ion-exchange nanofibers (IEX-NFs) and their composite polyelectrolyte membranes were prepared and characterized. The PVA based NFs are well dispersed and form a three-dimensional network structure in the polymer matrix, Nafion. All of the prepared membranes show a similar ion exchange capacity of ~1.0 mmol g-1. The ionic conductivities through the PVA- b PSS-NF/Nafion composite membranes are superior to that of the Nafion membranes, but the conductivity through the PVA-NF/Nafion composite membrane is half that of the Nafion membrane. Our electrokinetic measurements clearly indicate that a high density of ion-exchange groups on the NF surface results in a continuous ionic transport path in the polymer matrix. In addition, the mechanical strength of all of the NF-composite membranes is improved compared with that of the membranes without NF. PMID- 30293432 TI - Driving a Liquid Crystal Phase Transition Using a Photochromic Hydrazone. AB - The dynamic manipulation of the properties of soft matter can lead to adaptive functional materials that can be used in advanced applications. Here we report on a new chiral dopant, built on an isosorbide scaffold attached to two bistable hydrazone-based light switches that can be used to control the self-assembly, and hence photophysical properties, of nematic liquid crystals (LCs). The bistability of the switch allows kinetic trapping of various helical assemblies as a function of the photostationary states, resulting in the reflection of different wavelengths of light. Surprisingly, doping 5CB with the chiral switch, followed by irradiation with blue light, triggers an isothermal phase change from the helical cholesteric phase to the untwisted lamellar smectic A* phase. This transition was used to modulate the transparency of a LC film, resulting in a light-gated optical window. PMID- 30293433 TI - Development of a Highly Sensitive Direct Competitive Fluorescence Enzyme Immunoassay Based on a Nanobody-Alkaline Phosphatase Fusion Protein for Detection of 3-Phenoxybenzoic Acid in Urine. AB - 3-Phenoxybenzoic acid (3-PBA) is a human urinary metabolite of many pyrethroid insecticides and can be used as a biomarker to monitor human exposure to these pesticides. A rapid and sensitive direct competitive fluorescence enzyme immunoassay (dc-FEIA) for detecting 3-PBA on the basis of a nanobody (Nb) alkaline phosphatase (AP) fusion protein was developed. The anti-3-PBA Nb-AP fusion protein was expressed and purified. The 50% inhibitory concentration (IC50) and linear range of dc-FEIA were 0.082 and 0.015-0.447 ng/mL, respectively, with a detection limit of 0.011 ng/mL. The IC50 of dc-FEIA was improved by nearly ten times compared with those of one-step and three-step direct competitive enzyme-linked immunosorbent assay (dc-ELISA). Spiked urine samples were detected by both dc-FEIA and liquid chromatography-mass spectrometry (LC-MS), and the results showed good consistency between the two analysis methods, indicating the reliability of dc-FEIA based on the Nb-AP fusion protein for detecting 3-PBA in urine. PMID- 30293434 TI - Emanating Jets As Shaped by Surface Tension Forces. AB - We show that emanating jets can be regarded as growing liquid towers, which are shaped by the twofold action of surface tension: first the emanated fluid is being accelerated back by surface tension force, herewith creating the boundary conditions to solve the shape of the liquid tower as a solution of an equation mathematically related to the hydrostatic Young-Laplace equation, known to give solutions for the shape of pending and sessile droplets, and wherein the only relevant forces are gravity g and surface tension gamma. We explain that for an emanating jet under specific constraints all mass parts with density rho will experience a uniform time dependent acceleration a( t). An asymptotic solution is subsequently numerically derived by making the corresponding Young-Laplace type equation dimensionless and by dividing all lengths by a generalized time dependent capillary length lambdac( t) = [Formula: see text]. The time dependent surface tension gamma( t) can be derived by measuring both time dependent acceleration a( t) and time dependent capillary length lambdac( t). Jetting experiments with water and coffee show that the dynamic surface tension behavior according to the emanating jet method and with the well-known maximum bubble pressure method are the same, herewith verifying the proposed model. PMID- 30293435 TI - Keeping them interested: a national study of factors that change medical student interest in working rurally. AB - INTRODUCTION: In most countries it remains a challenge to sustain the rural medical workforce. Based on evidence that medical students with rural backgrounds are more likely than their urban peers to enter rural practice, medical schools may have rural entry pathways. It is less well established what happens to career intentions during medical school. This study assessed how rural intentions persist or change during medical school and sought factors associated with either persistence or change in rural intention. METHODS: Students who participate in the Medical Schools Outcomes Database and Longitudinal Tracking project complete surveys at entry to and exit from medical school. They are asked about demographics, career intentions and influencing factors. This study used data from students at both of New Zealand's medical schools from 2006 to 2016. Participants were placed into one of four groups: rural intention at entry and rural intention at exit (R-R), urban at entry and rural at exit (U-R), rural at entry and urban at exit (R-U) or urban at entry and urban at exit (U-U). 'Rural' was defined as an area with a population of 100 000 or fewer. Differences among the groups in demographics and influencing factors were analysed. RESULTS: Overall, 4368 students completed an entry survey (response rate 85.9%), and 2243 students completed an exit survey (response rate 66.4%). A third intended to work in a rural area; of these, 49% had a rural background and 51% an urban background. From the linked entry and exit data (n=1114), there were 239 (21.4%), 188 (16.8%), 135 (12.1%) and 552 (49.5%) students in the R-R, U-R, R-U and U-U groups respectively (p<0.001). Most students had a stable geographical career intention. Of those who changed, more moved towards a rural intention than away from it. Medical students with a persistent rural pattern had characteristics of a rural background (70%), being female (68%), New Zealand European (76%) or having involvement with a rural club for at least 1 year (45%). These students were also more likely to express a GP career intention as their first choice (25%). There were small differences in age, but otherwise no particular demographic factors were associated with students who changed intention. Similarly there were only small differences in perceived career influencing factors among groups. CONCLUSION: This large national study shows a stability of career location intention for the majority of students. It confirms earlier findings of the importance of rural background in rural career preference, but shows that women may have a higher propensity for a persisting rural interest. Apart from providing quality experience in rural areas for all students, and facilitating rural clubs, the study did not reveal any other strategies that might be used by medical schools to either increase or prevent the loss of rural interest. PMID- 30293436 TI - Reducing Telemetry Use Is Safe: A Retrospective Analysis of Rapid Response Team and Code Events After a Successful Intervention to Reduce Telemetry Use. AB - Interventions guiding appropriate telemetry utilization have successfully reduced use at many hospitals, but few studies have examined their possible adverse outcomes. The authors conducted a successful intervention to reduce telemetry use in 2013 on a hospitalist service using educational modules, routine review, and financial incentives. The association of reduced telemetry use with the incidence of rapid response team (RRT) and code activations was assessed in a retrospective cohort study of 210 patients who experienced a total of 233 RRT and code events on the inpatient internal medicine services from January 2012 through March 2015 at a tertiary care center. The incidence of adverse events for the hospitalist service was not significantly different during the intervention and postintervention period as compared to the preintervention period. Reducing inappropriate telemetry use was not associated with an increase in the incidence rates of RRT and code events. PMID- 30293437 TI - Investigational drugs in phase II clinical trials for moderate to severe plaque psoriasis - potential new treatments on the horizon. AB - INTRODUCTION: Psoriasis is a common immune disorder for which there are many FDA approved therapies. Older oral drugs had limited efficacy and considerable side effects. Biologics have been a major advance but require self-administered injections, and many patients prefer oral options. Because many patients fear needles, oral drugs are a welcome option. This review provides an update on oral drugs in Phase II development for psoriasis. Areas covered: A literature review was performed to identify these drugs by using search terms such as 'psoriasis', 'agents', 'drugs', and 'phase 2 development'. Baricitinib and KDO 25 are the oral drugs that appear to hold the most promise due to the balance they maintain between efficacy and adverse effects. If a RORgammat inhibitor can be identified that has no hepatotoxicity, then that may be the most promising new oral treatment. Expert opinion: Several new oral psoriasis medications are currently being investigated. One major challenge remains medication cost and insurance coverage. Phase III studies are needed to determine efficacy and safety in large cohorts of psoriasis patients. An increase in the number of approved oral medications for psoriasis would mean more choice for psoriasis patients.

PMID- 30293439 TI - Rituximab Exhibits Altered Pharmacokinetics in Patients With Membranous Nephropathy. AB - BACKGROUND: Rituximab (RTX) is a chimeric monoclonal anti-CD20 antibody used off label in the treatment of membranous nephropathy (MN). Unfortunately, limited information is available on the pharmacokinetics of therapeutic proteins such as RTX in patients with glomerular kidney diseases. OBJECTIVE: The current study evaluated RTX pharmacokinetics in patients with MN (n = 20) who received 4 RTX weekly intravenous infusions (375 mg/m2) over a month, with a repeat of the identical treatment at 6 months. Baseline patient characteristics were gender (17 male/3 female), age (49 +/- 13 years), and body surface area (2.2 +/- 0.24 m2). METHODS: Compartmental pharmacokinetic analyses were conducted using Phoenix, and comparisons of these parameters were made between the MN patients and published data from 2 reference populations without kidney diseases (follicular lymphoma and autoimmune disorders). RESULTS: Patients with MN exhibited a shorter half life, reduced volume of central compartment, decreased area under the serum concentration-time curve (exposure), and increased RTX clearance from the central compartment versus previous reports in the reference patient populations. CONCLUSIONS AND RELEVANCE: These results suggest that shorter half-life and lower exposures to RTX in patients with MN may necessitate higher doses and/or changes to dosing frequency to optimize the relationships between serum concentrations and therapeutic effects. PMID- 30293440 TI - A Chinese cross-sectional study on depression and anxiety symptoms in patients with psoriasis vulgaris. AB - Previous studies have reported a higher incidence of depression and anxiety in psoriasis patients compared to the general population, which has important implications for assessment and treatment. In this study, we determined the frequency of depression and anxiety in Chinese patients with psoriasis and its relationship with disease severity and other demographic variables. The study included 208 Chinese patients with psoriasis vulgaris. The Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder scale (GAD-7) were used to screen for depression and anxiety. The Psoriasis Area and Severity Index (PASI) was used to assess the severity of psoriasis. Of the 208 patients included in the study, 29 patients (13.9%) were positive for moderate-to-severe depression (PHQ-9 >= 10) and 22 patients (10.6%) were positive for anxiety (GAD-7 >= 10) symptoms. Both positive stress reactors who perceived stress as an exacerbating factor of psoriasis and moderate-to-severe psoriasis were found to be positive predictors for the presence of moderate-to-severe depression or anxiety symptoms while longer duration and late onset age played a protective role. In the sample of Chinese patients with psoriasis there was a clinically significant prevalence of depression and anxiety. Our study suggests that Chinese psoriasis patients should be screened for psychiatric comorbidities. PMID- 30293441 TI - Risk factors for antenatal anxiety: A systematic review of the literature. AB - BACKGROUND: Given the prevalence of antenatal anxiety and its consistent associations with adverse pregnancy and child outcomes, early detection and management of anxiety are essential. OBJECTIVE: The aim was to identify risk factors for anxiety among pregnant women by systematically reviewing original research. METHODS: Cross-sectional, case-control and cohort studies that examined associations between antenatal anxiety and at least one potential risk factor prospectively or retrospectively and measured anxiety independent from other mental health conditions were included. Studies rated strong/moderate in methodological quality appraisal were used to synthesise the evidence. RESULTS: Factors associated with greater risk of anxiety included previous pregnancy loss, medical complications, childhood abuse, intimate partner violence, denial/acceptance coping styles, personality traits, inadequate social support, history of mental health problems, high perceived stress and adverse life events. CONCLUSIONS: Several risk factors identified in this review are detectable in routine prenatal care visits (e.g. previous pregnancy loss, pregnancy complications), potentially modifiable (e.g. coping styles, social support, partner factors) and can be identified prior to pregnancy (e.g. psychosocial factors), underlining the significance of pre-conception mental health screening.

CONCLUSIONS: Promoting the welfare of psychiatry trainees requires a three-pronged approach.

PMID- 30293444 TI - Giving G a Meaning: An Application of the Bifactor-(S-1) Approach to Realize a More Symptom-Oriented Modeling of the Beck Depression Inventory-II. AB - The Beck Depression Inventory-II is one of the most frequently used scales to assess depressive burden. Despite many psychometric evaluations, its factor structure is still a topic of debate. An increasing number of articles using fully symmetrical bifactor models have been published recently. However, they all produce anomalous results, which lead to psychometric and interpretational difficulties. To avoid anomalous results, the bifactor-(S-1) approach has recently been proposed as alternative for fitting bifactor structures. The current article compares the applicability of fully symmetrical bifactor models and symptom-oriented bifactor-(S-1) and first-order confirmatory factor analysis models in a large clinical sample ( N = 3,279) of adults. The results suggest that bifactor-(S-1) models are preferable when bifactor structures are of interest, since they reduce problematic results observed in fully symmetrical bifactor models and give the G factor an unambiguous meaning. Otherwise, symptom oriented first-order confirmatory factor analysis models present a reasonable alternative. PMID- 30293445 TI - Convergent, Discriminant, and Concurrent Validity of Nonmemory-Based Performance Validity Tests. AB - To supplement memory-based Performance Validity Tests (PVTs) in identifying noncredible performance, we examined the validity of the two most commonly used nonmemory-based PVTs-Dot Counting Test (DCT) and Wechsler Adult Intelligence Scale-Fourth edition (WAIS-IV) Reliable Digit Span (RDS)-as well as two alternative WAIS-IV Digit Span (DS) subtest PVTs. Examinees completed DCT, WAIS IV DS, and the following criterion PVTs: Test of Memory Malingering, Word Memory Test, and Word Choice Test. Validity groups were determined by passing 3 (valid; n = 69) or failing ?2 (noncredible; n = 30) criterion PVTs. DCT, RDS, RDS-Revised (RDS-R), and WAIS-IV DS Age-Corrected Scaled Score (ACSS) were significantly correlated (but uncorrelated with memory-based PVTs). Combining RDS, RDS-R, and ACSS with DCT improved classification accuracy (particularly for DCT/ACSS) for detecting noncredible performance among valid-unimpaired, but largely not valid impaired examinees. Combining DCT with ACSS may uniquely assess and best supplement memory-based PVTs to identify noncredible neuropsychological test performance in cognitively unimpaired examinees. PMID- 30293446 TI - How secure are the secure psychiatric units in New South Wales? AB - OBJECTIVES: To evaluate the therapeutic security characteristics of the secure forensic mental health inpatient units in New South Wales, Australia. METHODS: This study evaluated all eight secure inpatient units in New South Wales using a validated tool, the Security Needs Assessment Profile. RESULTS: A pattern of decreasing therapeutic security across the secure units was found, consistent with their intended security levels, from high security through to open security. However, important inconsistencies across and between levels of security were highlighted. CONCLUSIONS: This study clarifies the therapeutic security structure of the New South Wales forensic mental health service, which is an essential first step in service development and reform. PMID- 30293447 TI - The mutagenic effect of psychostimulant modafinil in Wistar rats in vivo. AB - The demands imposed by today's world require a fast and efficient society, then, significant section of the population looks for support from psychotropic medicine. Modafinil is a psychostimulant that promotes wakefulness, it being recommended for treatment of narcolepsy, obstructive sleep apnea, and shift-work sleep disorder, besides being a cognitive function potentiator. However, chemical components of drugs can alter genetic material. Thus, the present study evaluated the cytotoxic and clastogenic/mutagenic potential of 0.25, 0.50, and 0.75 mg of Modafinil/mL of corn oil/100g body weight in acute treatments and subacute treatments, 15 days, to Rattus norvegicus, treated via gavage in a single daily dose. The drug was not cytotoxic at any of the evaluated doses in either of the treatments. However, the medicine showed clastogenic/mutagenic activity in the acute treatment group at the standard dose and at double dose. Data from the present study indicates that there should be greater caution as to the use of this psychostimulant by human beings. PMID- 30293448 TI - Alosetron versus traditional pharmacotherapy in clinical practice: effects on resource use, health-related quality of life, safety and symptom improvement in women with severe diarrhea-predominant irritable bowel syndrome. AB - OBJECTIVE: Severe diarrhea-predominant irritable bowel syndrome (IBS-D) is associated with decreased health-related quality of life (HRQOL) and increased health care costs. Treatment recommendations for IBS-D often start with traditional pharmacotherapy (TP), with escalation to alosetron, rifaximin or eluxadoline if there is no success. There has been no previous head-to-head clinical trial comparing IBS-D treatment outcome for alosetron versus TP. This study, GSK protocol S3B30020, evaluated resource use, work productivity, health related quality of life and global symptom response in women with IBS-D who were treated with alosetron or TP. METHODS: A total of 1956 patients who met criteria for severe IBS-D were randomized to treatment with alosetron 1 mg twice daily (BID) or only TP for up to 24 weeks. Work productivity and resource use were evaluated by standard questionnaires, HRQOL by the IBSQOL instrument and IBS symptoms by the Global Improvement Scale (GIS). RESULTS: Compared to only TP, alosetron-treated patients reported: (1) fewer clinic/office visits for any health problem (p = .0181) or for IBS-D (p = .0004); (2) reduced use of over-the counter medications for IBS-D (p < .0001); (3) fewer days of lost work productivity (p < .0001); (4) decreased restriction of social and outdoor activities (p < .0001); and (5) greater global improvement in IBS-D symptoms (p < .0001). Alosetron treatment improved HRQOL scores for all domains (p < .0001). Incidence of adverse events during alosetron use was not remarkable and was similar to that previously reported. CONCLUSIONS: Alosetron 1 mg BID significantly reduced health care utilization and lost productivity, and significantly improved global IBS symptoms, HRQOL, and participation in outdoor and social activities compared with treatment response to TP. PMID- 30293449 TI - Extended-release morphine sulfate and naltrexone hydrochloride (EMBEDA): naltrexone-associated withdrawal and abuse-related effects in patients with chronic pain and recreational opioid users. AB - OBJECTIVE: To review the effects of naltrexone on withdrawal-related adverse events (AEs) and euphoria-related effects, and the relationship between plasma naltrexone concentrations and withdrawal across EMBEDA (MSN; extended-release morphine sulfate with sequestered naltrexone) studies. METHODS: Five studies in pain patients and a safety review summarizing AE reports during the first year following approval of MSN were assessed for withdrawal reports. Three of these studies also assessed Clinical Opiate Withdrawal Scale (COWS) scores. Plasma naltrexone concentrations of MSN-treated individuals were summarized. Abuse potential was assessed in four studies in non-dependent recreational opioid users. RESULTS: Withdrawal AEs occurred in 13/1781 patients across five MSN studies, and 25/182 cases involving withdrawal were reported in the safety review. In three of these studies, 11/964 patients experienced moderate withdrawal (COWS score = 13-24) and 1/964 patients experienced moderately severe withdrawal (score = 28); all were either non-compliant with study drug, had undetectable plasma naltrexone concentrations, or were tapering to placebo. In >=89% of plasma naltrexone concentration samples from patients who took MSN (n = 166), naltrexone was below the limit of quantification (4.0 pg/mL). In four studies with non-dependent recreational opioid users (n = 118), crushed MSN was associated with significantly lower scores of drug liking, high, and take drug again than crushed morphine sulfate (p <= 0.005). CONCLUSIONS: When taken intact as directed, naltrexone in MSN does not precipitate withdrawal. However, when MSN is crushed, naltrexone mitigates, but does not eliminate, the euphorigenic effects of crushed morphine sulfate. PMID- 30293450 TI - Butea monosperma (Lam.) Taub. Bark fractions protect against free radicals and induce apoptosis in MCF-7 breast cancer cells via cell-cycle arrest and ROS mediated pathway. AB - Butea monosperma (Lam.) Taub. is an ethnomedicinal tree of remedial value in the treatment of diabetes, bone fractures, and liver and neurological disorders. However, the information available on DNA-protective and anti-proliferative potential of bark of this tree is scarce. In the present study, the extract/fractions obtained from bark of B. monosperma were evaluated for antioxidant, DNA-protective, and anti-proliferative activities, along with their phytochemical profiling for identifying major constituents present in them. Different extract/fractions, namely, Bmth (methanol), Bhex (hexane), Bchl (chloroform), and Beac (ethyl acetate), were prepared and evaluated for antioxidant activity using in vitro assays. Extract/fractions were also evaluated for anti-proliferative and apoptotic activity in human breast carcinoma cell line MCF-7, using in vitro assays, namely, MTT, clonogenic, and neutral comet assay, along with confocal microscopy and flow cytometry. Among all extract/fractions, a pronounced antioxidant activity was exhibited by Bchl and Beac fractions, in DPPH. (EC50 213.2 and 161.5 ug/mL, respectively), ABTS+. (EC50 139.3 and 44.1 ug/mL, respectively), and reducing power assay (EC50 86.7 and 84.5 ug/mL, respectively). Both fractions protected plasmid DNA against hydroxyl radical induced damage in plasmid nicking assay. Bchl and Beac were also observed to inhibit the growth of MCF-7 cells (GI50 203.7 and 246.5 ug/mL, respectively). Both fractions induced apoptosis in MCF-7 cells, by arresting the cell cycle in G1 and sub-G1 phase, respectively, enhancing ROS levels, decreasing mitochondrial membrane potential, and inducing double-strand DNA breaks. HPLC analysis revealed high kaempferol content in Bchl, and catechin, epicatechin, and gallic acid in Beac. PMID- 30293451 TI - Assessment of Bony Subfibular Impingement in Flatfoot Patients Using Weight Bearing CT Scans. AB - BACKGROUND:: Lateral hindfoot pain in patients with flatfoot deformity is frequently attributed to subfibular impingement. It remains unclear whether this is primarily due to bony or soft-tissue impingement. No studies have used weight bearing CT scans to evaluate subfibular impingement. METHODS:: Patients with posterior tibial tendonitis were retrospectively searched and reviewed. Subjects had documented flatfoot deformity, posterior tibial tenderness, weight-bearing plain radiographs, and a weight-bearing CT scan. CT scans were evaluated for calcaneofibular impingement on the coronal view and talocalcaneal impingement on the sagittal view. The distance between these structures was measured, along with the sinus tarsi volume. In the second part of this study, 6 normal volunteers underwent weight-bearing CT scans on a platform that held both feet in 20 degrees of varus, followed by 20 degrees of valgus. The same measurements were performed. RESULTS:: Thirty-five percent of flatfoot patients with posterior tibial tendonitis had bony impingement between the fibula and calcaneus on the coronal view. Thirty-eight percent had bony impingement between the talus and calcaneus on the sagittal view. Subjects with bony impingement based on CT scan had significantly higher talonavicular abduction angles on plain radiographs than those without impingement. Sinus tarsi volume decreased by more than half when the subtalar joint moved from varus to valgus in normal controls. CONCLUSION:: Bony subfibular impingement in patients with flatfeet was less common than previously reported. Accurate diagnosis of bony impingement may be useful for surgical decision-making. LEVEL OF EVIDENCE:: Level III, retrospective comparative study. PMID- 30293452 TI - Five alternative splicing variants of the TYR gene and their different roles in melanogenesis in the Muchuan black-boned chicken. AB - 1. The TYR gene encodes tyrosinase, a multifunctional enzyme that is essential for melanin biosynthesis in melanocytes. This experiment involved the cloning and characterisation of the TYR gene in chicken. Five alternative splice variants were identified in the black feather bulb and designated as TYR-AS1, TYR-AS2, TYR AS3, TYR-AS4 and TYR-AS5. 2. Among the 11 chicken tissues examined, the feather bulb, comb and skin showed higher levels of all TYR variants. All TYR variants were expressed at significantly different levels in black and white feather bulbs (P < 0.05) and may be involved in melanin formation in plumage. Only TYR-AS1, which plays an important role in muscle melanogenesis, was significantly differentially expressed between black and white muscle (P < 0.01). All TYR variants were expressed at significantly different levels in black and white skin (P < 0.01). 3. The mRNA expression levels of the 5 variants were closely associated with skin melanogenesis in the chicken. These findings provide new clues to the molecular mechanism of melanin formation in the Muchuan black-boned chicken. PMID- 30293453 TI - Pancreatic islet dysfunction in type 2 diabetes mellitus. AB - Islet dysfunction is a hallmark of type 2 diabetes mellitus (T2DM). Compelling evidence suggests that accumulation of islet amyloid in the islets of Langerhans significantly contribute to beta-cell dysfunction and diabetes. Emerging evidence implicates a role for cystic fibrosis transmembrane-conductance regulator in the regulation of insulin secretion from pancreatic islets. Impaired first-phase insulin responses and glucose homeostasis have also been reported in cystic fibrosis patients. The transforming growth factor-beta protein superfamily is central regulators of pancreatic cell function, and has a key role in pancreas development and pancreatic disease, including diabetes and islet dysfunction. It is also becoming clear that islet inflammation plays a key role in the development of islet dysfunction. Inflammatory changes, including accumulation of macrophages, have been documented in type 2 diabetic islets. Islet dysfunction leads to hyperglycemia and ultimately the development of diabetes. In this review, we describe these risk factors and their associations with islet dysfunction. PMID- 30293454 TI - No gold medals: Assessing Australia's international mental health performance. AB - OBJECTIVE: The objective of this study was to present an assessment of Australia's mental health system performance, within its social context, by comparison with other countries. METHOD: A review of existing literature and databases from both Australia and overseas was undertaken. Systems permitting international comparison of mental health and its social context are few. The review is limited in scope. RESULTS: Although Australia was one of the first nations to develop and adopt a national mental health policy (in 1992), the data that are available suggest that we are not World leaders across the identified domains. CONCLUSIONS: While international benchmarking can play an important role in fostering quality improvement, there are only limited mental health or social system performance data sources to utilise. It would be desirable for a more systematic international process to be established to review existing approaches and design a new multilateral strategy. It would be important that this new strategy reflected the full experience of mental health and its broader social context.

PMID- 30293456 TI - Value of perceived support on depressive symptoms and hazardous drinking among underserved HIV+ adults 50 and older. AB - The current study examined the association between perceived social support, depressive symptoms and alcohol use among people living with HIV (PLWH) 50 and older who identified as Black. Participants included 96 men and women ages 50 and older. Participants completed an interviewer-administered assessment examining mental and behavioral health functioning. Mediation analyses examined whether perceived support mediated the association between depressive symptoms and hazardous drinking. Depressive symptoms were significantly associated with hazardous drinking (B = .068, SE = .035, t = 1.92, p = 0.05) and negatively associated with having the desired amount of contact with a primary supporter (B = -.072, SE = .018, z = -3.96, p < 0.001). In addition, having the desired amount of contact with a confidant was negatively associated with hazardous drinking (B = -.543, SE = .208, t = -2.61, p 0 < .01). The effect of depressive symptoms on hazardous drinking when controlling for having adequate contact with a primary supporter was not significant (B = .033, SE = .04, t = .829, p = 0.41). Having a valued confidant mediated the association between depressive symptoms and hazardous drinking. Thus, social support interventions may be an effective method of reducing hazardous drinking among older PLWH. PMID- 30293457 TI - The effects of vest type dynamic elastomeric fabric orthosis on sitting balance and gross manual dexterity in children with cerebral palsy: a single-blinded randomised controlled study. AB - PURPOSE: To evaluate the effects of vest type dynamic elastomeric fabric orthosis on posture and balance during sitting and gross manual dexterity and to compare the efficacy of daily wearing time of 2 h versus 6 h. METHOD: Twenty-four children with cerebral palsy (CP) aged 3-9 years with GMFCS levels III and IV were randomised to either of three groups: (i) a control group who received only conventional exercise therapy, (ii) dynamic elastomeric fabric orthosis 2 h group who wore the orthosis for 2 h during therapy and dynamic elastomeric fabric orthosis 6 h group who wore the orthosis for 4 h in addition to the 2 h of wear along with therapy during hospital inpatient stay for 2 weeks. Children continued to use dynamic elastomeric fabric orthosis during the post-discharge period. The primary outcome measure was the Sitting Assessment Scale. The secondary outcome measurements were the sitting dimension of Gross Motor Function Measure, Box and Block Test and Parent Satisfaction Survey. Assessments were made before treatment, at post-treatment, at 1-month post-treatment, and at 3-months post treatment. Sitting Assessment Scale and Box and Block Test were also assessed when immediately after wearing the orthosis. This trial is registered with Clinicaltrials.gov, under number NCT03191552. RESULTS: All groups showed similar improvements except the control group which showed less improvement in Sitting Assessment Scale scores compared to the dynamic elastomeric fabric orthosis groups. Dynamic elastomeric fabric orthosis groups showed greater improvements compared to the control group in the Sitting Assessment Scale but not in the sitting dimension of Gross Motor Function Measure and Box and Block Test at post treatment, at 1-month post-treatment and at 3-months post-treatment. When the dynamic elastomeric fabric orthosis groups (2 h versus 6 h) were compared, there were no significant differences in any of the assessments. The Sitting Assessment Scale and Box and Block Test scores also improved immediately after the patients put on the orthosis. At 1-month post-treatment, parents of children in the control group reported less satisfaction than parents of the children in dynamic elastomeric fabric orthosis groups. CONCLUSIONS: Dynamic elastomeric fabric orthosis vest has an immediate effect on the sitting balance and gross manual dexterity. It also provides improvements in posture and balance during sitting. Wearing dynamic elastomeric fabric orthosis vest for 2 h during therapy is as much effective as wearing it for 6 h in children with CP in addition to therapy to improve sitting balance. Implications for rehabilitation Dynamic elastomeric fabric orthosis vest provides improvements in sitting balance when used in addition to conventional therapy in children with cerebral palsy. Wearing dynamic elastomeric fabric orthosis for 2 h and wearing dynamic elastomeric fabric orthosis vest for 6 h resulted in similar clinical outcomes. Dynamic elastomeric fabric orthosis vest has an immediate effect on sitting balance and gross manual dexterity in children with cerebral palsy. PMID- 30293458 TI - An exercise program for people with severe peripheral neuropathy and diabetic foot ulcers - a case series on feasibility and safety. AB - PURPOSE: To examine a non-weightbearing exercise program for persons with severe peripheral neuropathy (PN) and a diabetic foot ulcer in terms of feasibility and safety. MATERIALS AND METHODS: Five men (mean (SD) age of 68.2 (7.1) years) with diabetes, severe peripheral neuropathy and an active foot ulcer, participated in a 10-week exercise program. Program adherence, patient satisfaction, healing of foot ulcers, adverse advents, ability to perform activities of daily life, and changes in muscle strength were assessed. RESULTS: All participants completed the program with a session attendance from 85 to 95%, and with high satisfaction (>=9 points on a 10-point numeric rating scale). Only minor adverse events occurred, and ulcers were reduced for all participants, from a median of 1.9 (IQR, 1.1-7.3) cm2 to 0.0 (0.0-3.0) cm2. The distance on stationary bike was improved from a mean (SD) of 3.30 (1.1) to 5.36 (0.5) kilometers, and strength training loads were progressed. Ability to perform in self-selected activities of daily living improved from a median of 4.3 (2-5) to 6.7 (5-8) on the Patient Specific Functional Scale (0-10 points), while maximal isometric knee-extension muscle strength improved with 23%. CONCLUSIONS: A non-weightbearing exercise program for people with diabetes, severe peripheral neuropathy and foot ulcers seems feasible and safe. Further studies are needed to confirm these findings. Implications for rehabilitation An exercise program designed for people with severe peripheral neuropathy and diabetic foot ulcers can be safe by means of not compromising healing of foot ulcers. Feasible in terms of attendance and progression. An alternative to passive waiting for ulcer to heal in a population already deconditioned. PMID- 30293459 TI - Why it's time to focus on masculinity in mental health training and clinical practice. AB - OBJECTIVE: Men present with complex, diverse and often contradictory expressions of masculinity that are relevant to their health status. This article argues for the inclusion of masculinity into mental health curricula in Australia. Masculinity mediates health outcomes by influencing help seeking and engagement with treatment. CONCLUSION: An online curricula audit of publicly available information from Australian medical programs and their professional bodies reveals increasing awareness of the needs, but limited practical inclusion of masculinity models in training and practice. Described are the elements essential to training and subsequent clinical practice to curb the poor mental health outcomes of Australian men. PMID- 30293460 TI - Corrigendum. PMID- 30293461 TI - Design, synthesis, and biological evaluation of novel iso-flavones derivatives as H3R antagonists. AB - Histamine H3 receptor (H3R), a kind of G-protein coupled receptor (GPCR), is expressed mainly in the central nervous system (CNS) and plays a vital role in homoeostatic control. This study describes the design and synthesis of a series of novel H3R antagonists based on the iso-flavone scaffold. The results of the bioactivity evaluation show that four compounds (1c, 2c, 2h, and 2o) possess significant H3R inhibitory activities. Molecular docking indicates that a salt bridge, pi-pi T-shape interactions, and hydrophobic interaction all contribute to the interaction between compound 2h and H3R. PMID- 30293462 TI - Interleukin-6 measured using the automated electrochemiluminescence immunoassay method for the identification of intra-amniotic inflammation in preterm prelabor rupture of membranes. AB - INTRODUCTION: We aimed to compare the amniotic fluid interleukin (IL)-6 concentrations measured using the automated electrochemiluminescence immunoassay method and ELISA, and to establish an IL-6 concentration cut-off value for intra amniotic inflammation (IAI) in preterm prelabor rupture of membranes (PPROM), which can be used in the automated electrochemiluminescence immunoassay method. MATERIALS AND METHODS: A total of 120 women with PPROM were included in this study. Amniotic fluid samples were obtained via transabdominal amniocentesis. IL 6 concentrations were assessed using both the automated electrochemiluminescence immunoassay method and ELISA, the current gold standard. IAI was defined as an amniotic fluid IL-6 concentration of >= 2600 pg/mL measured using ELISA. RESULTS: A correlation between both assays was found (Spearman's rho = 0.97; p < 0.0001). Based on the receiver-operating characteristic curve for the identification of IAI (area under the curve = 0.99), a cut-off value of >= 3000 pg/mL was selected for the automated electrochemiluminescence immunoassay method with a sensitivity of 88%, specificity of 99%, positive predictive value of 97%, negative predictive value of 96%, and likelihood ratio of 76. PMID- 30293463 TI - Auditory brainstem response in full-term neonates born to mothers with iron deficiency anemia: relation to disease severity. AB - BACKGROUND: Iron is crucial for fetal brain development; however, there are insufficient data regarding the effects of maternal iron deficiency anemia (IDA) on auditory neural maturation. AIM: We evaluated the effect of maternal IDA on auditory brainstem response (ABR) in full-term neonates. METHODS: Out of 223 pregnant women, 50 were diagnosed as having IDA and 50 healthy mothers were enrolled as controls. ABR test was done for the studied neonates within 48 hours after birth and at 3 months. RESULTS: We found that hemoglobin and iron profile were lower in neonates born to anemic mothers compared with controls. Of 100 neonates screened for ABR, 25 failed the test (all of them were born to anemic mothers). The majority of neonates who failed the screening ABR test (88%) had latent iron deficiency (cord blood ferritin 11-75 ug/L). After 3 months, 85 neonates underwent diagnostic ABR test which revealed significantly prolonged interpeak latencies I-III, III-V, and I-V among neonates born to IDA mothers compared with the control group. Within the IDA group, all interpeak latencies were more prolonged in neonates with latent iron deficiency and in those born to mothers with serum ferritin <15 ug/L. Logistic regression analysis showed that maternal hemoglobin and mean corpuscular volume could predict neonatal ABR results. CONCLUSIONS: IDA during late pregnancy adversely affects cord blood iron and hearing status. ABR results are closely related to the severity of maternal and neonatal iron status. Antenatal screening of pregnant mothers is needed to improve fetal iron status and prevent abnormal auditory maturation. PMID- 30293465 TI - Local recurrence of brain metastasis reduced by intra-operative hyperthermia treatment. AB - PURPOSE: Brain metastasis is a common complication in cancer patients. Local recurrence after total resection of metastatic brain tumor has been frequently reported. In this study, we developed a new hyperthermia device and applied it to metastatic brain tumor patients intra-operatively to study if hyperthermia treatment could reduce local tumor recurrence. MATERIALS AND METHODS: A total of 63 metastatic brain patients were enrolled in the study with an informed consent obtained from every patient. After total resection of the tumor, the hyperthermia device was applied intra-operatively to the resection cavity. The surrounding brain tissue at 5 mm in depth from the tumor resection margin was raised to 42.5 degrees C for a total of 60 minutes (Clinical Research Information Service Registration Number: KCT0001308). RESULTS: A total of 10 local recurrences were observed in 63 patients who received hyperthermia treatment showing a local recurrence rate of 15.8%. It was significantly lower than the local recurrence rate of those who received conventional treatment (34%) when analyzed with one tailed z-test (p value: .001). Kaplan-Meier analysis also showed a significantly lower recurrence rate in the hyperthermia treatment group (p value: .0003). Complications included two cases of seizures and two cases of wound infection. CONCLUSIONS: Results of this study suggest that intra-operative hyperthermia treatment after total resection of metastatic brain tumor could reduce local recurrence of tumor. We believe that intra-operative hyperthermia treatment could be used as an adjuvant therapy to surgery and post-operative radiotherapy, or as a salvage treatment in patients who cannot receive further radiotherapy. PMID- 30293464 TI - A clinically oriented computer model for radiofrequency ablation of hepatic tissue with internally cooled wet electrode. AB - PURPOSE: To improve the computer modelling of radiofrequency ablation (RFA) by internally cooled wet (ICW) electrodes with added clinically oriented features. METHODS: An improved RFA computer model by ICW electrode included: (1) a realistic spatial distribution of the infused saline, and (2) different domains to distinguish between healthy tissue, saline-infused tumour, and non-infused tumour, under the assumption that infused saline is retained within the tumour boundary. A realistic saline spatial distribution was obtained from an in vivo pig liver study. The computer results were analysed in terms of impedance evolution and coagulation zone (CZ) size, and were compared to the results of clinical trials conducted on 17 patients with the same ICW electrode. RESULTS: The new features added to the model provided computer results that matched well with the clinical results. No roll-offs occurred during the 4-min ablation. CZ transversal diameter (4.10 +/- 0.19 cm) was similar to the computed diameter (4.16 cm). Including the tumour and saline infusion in the model involved (1) a reduction of the initial impedance by 10 - 20 Omega, (2) a delay in roll-off of 20 s and 70 - 100 s, respectively, and (3) 18 - 31% and 22 - 36% larger CZ size, respectively. The saline spatial distribution geometry was also seen to affect roll-off delay and CZ size. CONCLUSIONS: Using a three-compartment model and a realistic saline spatial distribution notably improves the match with the outcome of the clinical trials. PMID- 30293466 TI - The direct and indirect costs of epilepsy in Poland estimates for 2014-2016 years. AB - BACKGROUND: According to the current data, around 1% of the Poland population have epilepsy, which comprises about 400,000 people. This group of patients requires life-long therapy including both drug therapy and hospitalization. The character of the epilepsy has a significant impact on the expenses borne by individual patients, and the prevalence of the disease has a significant impact on the health care system. METHODS: This article aims to measure the direct and indirect costs of epilepsy in Poland estimates for the years 2014-2016 (top-down approach). We use a modified human capital approach and a unique dataset provided by the number of Polish institutions including National Health Fund, Social Insurance Institution, and Central Statistical Office. RESULTS: Epilepsy burden in Poland is significant. In the years 2014-2016, the total direct cost of epilepsy amounted to, respectively, 355 mln PLN (84 mln EUR), 368 mln PLN (87 mln EUR), and 373 mln PLN (88 mln EUR), but the total indirect cost amounted to 1 bn PLN (239 mln EUR), 949 mln PLN (224 mln EUR), and 848 mln PLN (200 mln EUR). CONCLUSIONS: Direct and indirect costs of epilepsy can be a useful input for health technology analyses of drugs or economic impact assessments of public health programs. PMID- 30293467 TI - Analgesic effect of preoperative dezocine-based local anesthesia in patients undergoing inguinal hernia repair. AB - Objective This study was performed to investigate the analgesic effects of intramuscular injection of dezocine-based local anesthesia in patients undergoing inguinal hernia repair. Methods A total of 120 patients underwent local herniorrhaphy from July 2015 to December 2016 and were randomly divided into 2 groups: the dezocine group, in which a preoperative intramuscular injection of dezocine was administered, and the control group, in which no dezocine injection was administered. The patients' pain and comfort levels were evaluated at 30 minutes, 2 hours, 6 hours, 12 hours, and 24 hours postoperatively. Results The visual analog scale scores at 30 minutes, 2 hours, 6 hours, 12 hours, and 24 hours were significantly lower in the dezocine than control group. In the Bruggemann comfort scale evaluation, patients who received dezocine injections showed significantly greater comfort than those in the control group at 30 minutes, 2 hours, 6 hours, 12 hours, and 24 hours. No adverse reactions occurred in the dezocine group. Conclusions Dezocine-based local anesthesia can attenuate postoperative pain and increase the comfort level during and after herniorrhaphy.

AB - AIM: To evaluate obstetric and perinatal outcomes of twin pregnancies obtained after in vitro fertilization with donated oocytes. METHODS: This is a case control study comparing 50 women with twin pregnancies after oocyte donation (OD) and 50 women after in vitro fertilization with autologous oocytes. Clinical records were reviewed and obstetric and perinatal outcome variables including rates of preeclampsia, gestational diabetes, pregnancy-induced hypertension, preterm delivery, premature rupture of membranes, cesarean delivery, birth weight, Apgar score, pH test were compared. RESULTS: Women in the OD group were significantly older than those in the AO group (mean 40.8 versus 36 years old, p < .001). There were a higher risk of preeclampsia (OD 24% versus AO 8%), cesarean delivery (OD 90% versus AO 66%), and preterm birth before 37 weeks (OD 52% versus AO 32%). After adjustment for maternal age, only the risk of preterm birth remained significantly higher (OR 3.2 (1.15-8.86); p = .025). Comparing neonatal outcomes, there were no differences in birth weight, pH or Apgar score at birth. CONCLUSIONS: Twin pregnancies after OD are associated with a higher risk of preterm birth before 37 weeks of gestation. However, this did not translate into increased rate of adverse perinatal outcomes. PMID- 30293470 TI - Risk factors related to unnecessary emergency medical services transport for pediatric patients. AB - Objectives This study evaluated unnecessary emergency medical services (EMS) transport for pediatric patients depending on whether they received emergency department (ED) treatment after EMS transport. Methods Pediatric patients were divided into two groups according to whether they received treatment at the ED (ED treatment) or did not receive treatment at the ED (non-ED treatment). Results The non-ED treatment group comprised 65 of the total 794 patients. The elapsed time from scene to arrival at the ED was longer in the non-ED treatment group than in the ED treatment group. Weekdays as the days of EMS transport, ground falls rather than traffic accidents as the reason for non-disease-related symptoms, and no immobilization for prehospital treatment were risk factors for non-ED treatment in EMS-transported patients. Causes of not receiving ED treatment for the non-ED treatment group were the patient's or caregiver's decision (12%) and the doctor's suggestion (88%). Conclusions Weekdays rather than weekends, ground falls rather than traffic accidents, and no immobilization before hospital are risk factors for not receiving ED treatment. The most common cause of not receiving ED treatment is the doctor's suggestion. PMID- 30293471 TI - Stability of plasma proteins and factors in Chinese universal pooled plasma. AB - Objective This study aimed to determine the precision dose of Chinese universal pooled plasma (CUPP) developed by our laboratory, and the stability of plasma proteins and factors. Methods A total of 100 single fresh-frozen plasma (FFP) units were selected to test plasma proteins, including total protein, albumin, fibrinogen, factor V, factor VIII, antithrombin-III, and protein C. Different pooling protocols with 20, 40, 60, 80, and 100 units were used to optimize the number of pooled units. The pooled plasma was then used to further evaluate the optimal storage conditions and duration at 22 degrees C, 4 degrees C, and -20 degrees C. Results There were considerable differences in plasma protein levels among single units of FFP. After different pooling protocols, the mean value of plasma proteins did not significantly change. However, with a larger number of pooled samples, plasma proteins were more stable with a smaller standard deviation. Acceptable storage for CUPP was achieved with storage for 1 day at 22 degrees C, 4 days at 4 degrees C, and 3 months at -20 degrees C. Conclusion A uniform level of plasma proteins and factors in CUPP appears to support establishment of a precise dose of plasma. PMID- 30293472 TI - Associations between socioeconomic status, atrial fibrillation, and outcomes: a systematic review. AB - BACKGROUND: Atrial fibrillation (AF) is a growing epidemic and evidence of a relationship to socioeconomic status (SES) is inconsistent. We aimed to summarize the literature about SES and AF and defined two objectives: (1) To examine the association between SES and the risk of AF; (2) To examine the association between SES and AF-related outcomes in an AF-population. METHODS: We performed a separate search for each objective in Ovid-MEDLINE and Ovid-Embase. For objective 1, the population included was healthy participants and outcome of interest was AF. For objective 2, the population included were patients with AF and outcome of interest was mortality, treatment, ablation for AF, knowledge about AF, and morbidity. RESULTS: For objective 1, 12 studies were included. No consistent pattern for an association between SES and the risk of AF was discovered. For objective 2, 39 studies comprising 42 outcomes were included. The majority of studies showed an association between low SES and increased mortality and morbidity. CONCLUSION: Low SES was associated with poorer outcomes when AF was present. These findings may imply that health-care professionals and policy interventions should focus on the promotion of AF-education and management among patients with AF and low SES. PMID- 30293473 TI - Prostate shape significantly affects the HoLEP procedure time and energy usage: A retrospective pilot study. AB - INTRODUCTION: In this study we evaluate the influence of longitudinal and transverse length of prostate size measured on the magnetic resonance imaging (MRI) scan on the overall outcomes of HoLEP. MATERIAL AND METHODS: The patients were divided into two groups based on the shape of the prostate. Group 1 had a longitudinal shape with a longitudinal diameter greater than the transverse diameter, whereas group 2 had an oval shape with a transverse diameter greater than the longitudinal diameter. The pre-operative, peri-operative and the one month post-operative data along with the urinary parameters were then evaluated. RESULTS: The two groups were comparable with regard to their pre-operative values. While the median lobe enucleation time and morcellation time showed no difference, group 1 showed a significantly shorter (p < 0.01) operative time for lateral lobe enucleation, lower laser energy usage and better enucleation efficiency. However, there was no difference in the median lobe enucleation time, morcellation time, haemoglobin drop, duration of urethral catheterization and hospital stay. The groups were also comparable with regard to the improvement in urinary parameters and complications. CONCLUSION: Prostate shape plays a significant role in the surgical treatment of BPH. PMID- 30293474 TI - Changes of arterial pressure following relief of obstruction in adults with hydronephrosis. AB - BACKGROUND: As much as 20% of all cases of hypertension are associated with kidney malfunctions. We have previously demonstrated in animals and in pediatric patients that hydronephrosis causes hypertension, which was attenuated by surgical relief of the ureteropelvic junction (UPJ) obstruction. This retrospective cohort study aimed to investigate: (1) the proposed link between hydronephrosis, due to UPJ obstruction, and elevated arterial pressure in adults; and (2) if elevated blood pressure in patients with hydronephrosis might be another indication for surgery. MATERIALS AND METHODS: Medical records of 212 patients undergoing surgical management of hydronephrosis, due to UPJ obstruction, between 2000 and 2016 were assessed. After excluding patients with confounding conditions and treatments, paired arterial pressures (i.e. before/after surgery) were compared in 49 patients (35 years old; 95% CI 29-39). Split renal function was evaluated by using mercaptoacetyltriglycine (MAG3) renography before surgical management of the hydronephrotic kidney. RESULTS: Systolic (-11 mmHg; 95% CI 6-15 mmHg), diastolic (-8 mmHg; 95% CI 4-11 mmHg), and mean arterial (-9 mmHg; 95% CI 6-12) pressures were significantly reduced after relief of the obstruction (p < 0.001). Split renal function of the hydronephrotic kidney was 39% (95% CI 37-41). No correlations were found between MAG3 and blood pressure level before surgery or between MAG3 and the reduction of blood pressure after surgical management of the UPJ obstruction. CONCLUSIONS: In adults with hydronephrosis, blood pressure was reduced following relief of the obstruction. Our findings suggest that elevated arterial pressure should be taken into account as an indication to surgically correct hydronephrosis.

Although researchers have established various film clip sets for different cultures, the few that exist related to Chinese culture do not adequately address positive emotions. The main purposes of the present study were to establish a standardised database of Chinese emotional film clips that could elicit more categories of reported positive emotions compared to the existing databases and to expand the available film clips that can be used as neutral materials. Two experiments were conducted to construct the database. In experiment 1, 111 film clips were selected from more than one thousand Chinese movies for preliminary screening. After 315 participants viewed and evaluated these film clips, 39 excerpts were selected for further validation. In experiment 2, 147 participants watched and rated these 39 film clips, as well as another 8 excerpts chosen from the existing databases, to compare their validity. Eventually, 22 film excerpts that successfully evoked three positive emotions (joy, amusement, and tenderness), four negative emotions (moral disgust, anger, fear, and sadness), and neutrality formed the standardised database of Chinese emotional film clips. PMID- 30293476 TI - A case report of TB versus idiopathic granulomatous mastitis with erythema nodosum, reactive arthritis, cough, and headache. AB - Tuberculous mastitis (TBM) is relatively rare disease with an incidence ranging between 0.1 and 4%. Most of the cases are culture negative and often mistaken with chronic benign idiopathic granulomatous mastitis (IGM). It is very crucial to distinguish culture negative TBM from other causes of mastitis as the treatment differs tremendously. We describe here in a young woman originally from India and residing in Qatar; a non endemic area of tuberculosis; for more then fifteen years. She presented with 2 months history of right breast mass, followed by low grade fever, dry cough, headache, erythema nodosum, arthritis, and arthralgia. In view of the origin of the patient, positive family history for tuberculosis and positive quantiferon, the patient was started empirically on anti-tuberculous treatment (ATT). One week later she developed paradoxical reaction to ATT. This case illustrates unusual and rare manifestations of primary TBM and highlights the importance of differentiating and treating culture negative TBM from IGM. PMID- 30293478 TI - Examining Validity of the Print Tool Compared With Test of Handwriting Skills Revised. AB - Handwriting assessments offer practitioners an objective measure to determine handwriting deficits, track student progress, and provide evidence for the use of occupational therapy intervention. This study determines the concurrent validity of the Print Tool with the Test of Handwriting Skills-Revised (THS-R) and examines the alignment of teacher perception with the Print Tool. Participants included 46 first- and second-grade students. All participants completed both handwriting assessments, and classroom teachers ( n = 4) rated each students' overall handwriting performance and potential areas of concern addressed by the Print Tool. The Print Tool overall scores have a strong correlation ( r = .606) with THS-R standard scores, suggesting good concurrent validity. Median Print Tool overall scores increased with each successive teacher rating classification, supporting alignment with teacher perception. This study provides preliminary evidence for the use of the Print Tool by occupational therapy practitioners to identify potential handwriting deficits that also align with teacher perception of performance. PMID- 30293477 TI - Words in larger font are perceived as more important: explaining the belief that font size affects memory. AB - Words presented in larger font size are considered more memorable and rated with higher judgments of learning (JOLs). One explanation for this phenomenon is that people believe that font size affects memory. However, it is not clear why people hold this belief. One alternative is that font size represents importance, with larger fonts implying more relevant information. More important information is judged as more memorable and is, in fact, better remembered. In Experiments 1 and 2 we presented words in small (18 points) and extra-large font (250 points) and found higher JOLs and higher judgments of importance with extra-large fonts. A mediation analysis showed that importance accounted for 21-23% of the effect of font size on JOLs. In Experiment 3, we tested whether processing fluency was higher with the extra-large font. In a lexical decision task, participants were slower at detecting words and non-words with extra-large than small font, which is the opposite of what the processing fluency hypothesis predicts. This result shows that the font-size effect persists even in conditions in which perceived fluency should be lower. In sum, this research explained the belief that font size affects memory because words in larger fonts are considered more important. PMID- 30293479 TI - Negev Bedouin Teachers' Attitudes Toward ADHD and Its Pharmacological Treatment. AB - Little is known about the attitudes of Negev Bedouin toward attention deficit/hyperactivity disorder (ADHD) and its pharmacological treatment. This study examines the perspectives of Negev Bedouin teachers on pharmacological treatment. Thirty-six teachers are asked to consider how their views influence the way they relate to pupils' parents. A grounded-theory analysis of semistructured interviews illuminates ambivalence in teachers' attitudes. Teachers, like the rest of their community, when asked about the implications of an ADHD evaluation for their children, respond that ADHD and its pharmacological treatment cause dishonor. When asked what ADHD means when it is their pupils who are diagnosed and treated, however, teachers, like the education establishment, accept the need for medication. However, they fail to communicate this need to parents because their attempts to do so show parents that they consider their children "flawed"-causing parents to oppose treatment even more lest they succumb to social stigma. PMID- 30293480 TI - How Funerals Accomplish Family: Findings From a Mass-Observation Study. AB - The article analyses how potentially conflicting frames of grief and family operate in a number of English funerals. The data come from the 2010 Mass Observation directive "Going to Funerals" which asked its panel of correspondents to write about the most recent funeral they had attended. In their writings, grief is displayed through conventional understandings of family. Drawing on Randall Collins, we show how the funeral stratifies mourners into family or nonfamily, a stratification accomplished-by family and nonfamily-through both outward display and inner feeling. The funerals described were more about a very traditional notion of family than about grief; family trumped grief, or at least provided the frame through which grief could be written about; and perceptions of "family" prompted emotions which in turn defined family. The funerals were portrayed as a distinct arena privileging family over the fluid and varied personal attachments highlighted in both the new sociology of personal life and in the concept of disenfranchised grief. PMID- 30293481 TI - Niraparib - A promising drug with hematological toxicity. AB - Ovarian cancer is the second most common and the most lethal gynecological malignancy in the western world. Unfortunately, there are lack of methods for early screening and diagnosis of the disease. Because of this, most of the cases are diagnosed at an advanced stage and have poor prognosis. The standard treatment of ovarian cancer is maximal cytoreductive surgical debulking followed by platinum-based chemotherapy. There are new molecular agents available for maintenance therapy of ovarian cancer including anti-angiogenic therapies, poly adenosine diphosphate ribose polymerase inhibitors, inhibitors of growth factor signaling, or folate receptor inhibitors, as well as several immunotherapeutic approaches. Niraparib is a poly adenosine diphosphate ribose polymerase inhibitor that has shown to be clinically effective as maintenance therapy in patients with platinum sensitive, recurrent ovarian cancer. Studies have shown the median duration of progression-free survival was significantly longer among those receiving niraparib than among those receiving placebo, regardless of presence or absence of BRCA gene mutations or homologous recombination deficiency status. Studies have shown that treatment-emergent Grade 3 or Grade 4 hematological events were observed in patients receiving niraparib including thrombocytopenia (33.8%), anemia (25.3%) and neutropenia (19.6%). Most of the hematological laboratory abnormalities occurred within the first three treatment cycles. After dose adjustment, the incidence of hematological abnormalities was infrequent beyond cycle 3. We are reporting two cases of Grade III/IV neutropenia and thrombocytopenia in patients treated with niraparib in our institution. Unfortunately, one of the patients succumbed to septic shock secondary to right lower lobe pneumonia while severely neutropenic. The second patient's blood counts improved after discontinuing the medication and with supportive transfusions during the hospitalization. PMID- 30293482 TI - Attribution of intentions and context processing in psychometric schizotypy. AB - INTRODUCTION: Impairment in Theory of mind (TOM) has frequently been associated with schizophrenia and with schizotypy. Studies have found that a tendency to over-attribute intentions and special meaning to events and to people is related to positive psychotic symptoms. Further, it has been suggested that this intentionality bias may be due to a broader deficit in context processing (CP). The aim of the present study was thus to investigate the relationship between positive schizotypy and both over-attribution of intentions and contextual processing. METHODS: One-hundred and nineteen healthy individuals completed the Schizotypal Personality Questionnaire and were assessed with tasks measuring contextual treatment and ToM. RESULTS: Results revealed that positive schizotypy was significantly related to an over-attribution of intentions on the ToM task and with a faster processing of implicit context. Partial correlational analyses indicated that the association between the attribution of intentions and positive schizotypy was not explained by a deficit of CP. In contrast, stepwise multiple regression analyses showed that both an over-attribution of intentions and a faster processing of implicit context significantly predicted positive schizotypy. CONCLUSIONS: These results show that an over-attribution of intention is independent from a broader deficit in context information processing and that they both possibly contribute to the development and maintenance of positive psychotic symptoms.

AB - This article explores how six Pakistani Muslim women interpret cultural concepts of izzat (honor and self-respect); what role, if any, it has in their lives; and whether there is interplay between upholding izzat and the participants' help seeking strategies for mental health and well-being. Semistructured interviews were conducted and analyzed with an interpretative phenomenological analytic framework. Three themes were identified: (a) "the rules of izzat," (b) "negotiating tensions," and (c) "speaking out/breaking the 'rules.'" Findings highlighted new insights into the understanding of izzat and the implications these cultural concepts have for strategies in managing or silencing of psychological distress. Interviews illustrated tensions the participants experience when considering izzat, how these are negotiated to enable them to self-manage or seek help, and possible life experiences that might lead to self harm and attempted suicide. Notably, cultural codes, in particular izzat, appear to vary over the life course and are influenced by migration. PMID- 30293485 TI - What's ours is yours: recall of history for lesser-known countries is guided by one's own national history. AB - The present studies examine how people recall history. Sometimes, certain national histories are well known and sometimes they are not. We propose that, under certain circumstances, culturally distinctive representations of typical national histories can be used to guide recall, particularly in cases where the history is not well known. We focus on three national samples with varied levels of knowledge about each history: Great Britain, India, and the United States. In Study 1, we establish typical historical event templates for each nation consisting of events that a large proportion of participants from each sample identify as important in a typical nation's history. We examine points of divergence between the different groups' typical event templates and the valences of these events. In Study 2, we test and find that, in conditions of less knowledge, participants tend to refer to particular historical events that coincide with events unique to their own group's typical history. In Study 3, we demonstrate that this effect can be found even when a group possesses a reasonable amount of knowledge about the target country. We conclude by discussing the implications in relation to how such a retrieval strategy might inform interpretations of events in the present. PMID- 30293486 TI - Correlation of imaging and intraoperative findings in Pott's puffy tumour. AB - Introduction Pott's puffy tumour is characterised by frontal bone osteomyelitis accompanied by subperiosteal abscess. It can be further complicated by intracranial extension of the infectious process. Case presentation A 12-year-old boy initially presented with signs and imaging findings of pan-sinusitis. Despite antibiotic therapy, there was progressive swelling of the forehead region. Subsequent imaging studies revealed osteomyelitis of frontal bone, subcutaneous abscess and extension into intracranial space. The abscesses were surgically drained, and craniectomy for osteomyelitis was carried out. Conclusion The initial symptoms of Pott's puffy tumour can be subtle, and antibiotic use may mask the underlying sinister involvement of intracranial structures. Imaging plays an important role both in diagnosis and detection of possible intracranial complications. PMID- 30293487 TI - Living Arrangements, Offspring Migration, and Health of Older Adults in Rural China: Revelation From Biomarkers and Propensity Score Analysis. AB - OBJECTIVE: We examine the combined effects of living arrangements and outmigration of adult children on rural older adults' health profiles, measured by biomarker data from the China Health and Retirement Longitudinal Study 2011. METHOD: We employ biomarker data and propensity score analysis which allows us to effectively deal with selection issues that are commonly observed in the literature. RESULTS: We show complex health implications of living arrangements and offspring migration. Living in a traditional multigenerational household has limited health benefits to older adults. However, older parents of migrants who live in a multigenerational household have better fitness in blood pressure. Their advantage over parents of migrants in other living arrangements suggests added benefits of the presence of grandchildren. DISCUSSION: This study bridges the living arrangement and migration literature on health by showing that health effects of adult children's migration on older adults are contingent upon their living arrangements. PMID- 30293489 TI - Translation and validation of the Chinese version of the Cancer Stigma Scale. AB - Purpose To test the reliability and validity of the Chinese version of the Cancer Stigma Scale (CASS). Methods After translation, back-translation and cross cultural adaptation of the CASS into Chinese (C-CASS), a random online survey of the general population in China was conducted. Reliability was analyzed by internal consistency (Cronbach's alpha) and construct validity was analyzed by confirmatory factor analysis. The C-CASS was evaluated in a sample of 382 non cancer patients through online format. Results The study found that the C-CASS had satisfactory internal reliability (Cronbach's alpha of the overall scale and six components was 0.88 and 0.70-0.89, respectively). Confirmatory factor analysis confirmed the six-factor structure (chi2/df = 2.2, GFI = 0.91, CFI = 0.94, RMSEA = 0.056, SRMR = 0.065). Younger individuals and those who had less knowledge of cancer showed more negative attitudes towards cancer. Conclusion The C-CASS had adequate internal consistency, reliability and indices of model fit, allowing its feasible use to assess levels of cancer stigma in Chinese populations. PMID- 30293488 TI - Anti-NMDA receptor encephalitis presenting as isolated aphasia in an adult. AB - Anti-NMDA receptor (NMDA-r) encephalitis is a relatively rare cause of autoimmune encephalitis with divergent clinical presentations. We report a case of an adult patient with anti-NMDA-r encephalitis presenting with isolated, abrupt-onset aphasia. Her condition remained unaltered over a period of 6 months. The patients' electroencephalogram findings were typical for NMDA-r encephalitis; however, her magnetic resonance imaging and cerebrospinal fluid analysis were normal. She responded well to immunotherapy, and aphasia eventually resolved. The natural course of the present case contradicts the rapidly progressive nature of typical NMDA-r encephalitis. Furthermore, it broadens the clinical spectrum of anti-NMDA-r encephalitis, to incorporate isolated, nonprogressive aphasia. PMID- 30293490 TI - Adaptive non-inferiority margins under observable non-constancy. AB - A central assumption in the design and conduct of non-inferiority trials is that the active-control therapy will have the same degree of effectiveness in the planned non-inferiority trial as in the prior placebo-controlled trials used to define the non-inferiority margin. This is referred to as the 'constancy' assumption. If the constancy assumption fails, decisions based on the chosen non inferiority margin may be incorrect, and the study runs the risk of approving an inferior product or failing to approve a beneficial product. The constancy assumption cannot be validated in a trial without a placebo arm, and it is unlikely ever to be met completely. When there are strong, observable predictors of constancy, such as dosing and adherence to the active-control product, we can specify conditions where the constancy assumption will likely fail. We propose a method for using measurable predictors of active-control effectiveness to specify non-inferiority margins targeted to the planned study population characteristics. We describe a pre-specified method, using baseline characteristics or post baseline predictors in the active-control arm, to adapt the non-inferiority margin at the end of the study if constancy is violated. Adaptive margins can help adjust for constancy violations that will inevitably occur in real clinical trials, while maintaining pre-specified levels of Type I error and power. PMID- 30293491 TI - The elderly as a target for obesity treatment. AB - The prevalence of obesity is increasing in the elderly population. The primary goal of obesity therapy in elderly is the improvement of metabolic complications and the prevention of severe functional limitations. Clinical studies could demonstrate that the combination of nutritional intervention and physical exercise is of advantage to improve the functional status. Study evidence about the efficacy and safety of medication for weight reduction in elderly is limited, and the risks of bariatric surgery outweigh the possible benefits. The test battery of the comprehensive geriatric assessment is an important tool to determine body composition, nutritional status as well as functional and cognitive capacities of the elderly patient. These results are of central importance for the treatment plan and goals. PMID- 30293492 TI - PEGylated insulin Lispro (LY2605541): clinical overview of a new long-acting basal insulin analog in the treatment of Type 2 diabetes mellitus. AB - Neutral Protamine Hagedorn insulin with an intermediate action profile has been in use for many years for the treatment of Type 1 diabetes and as an option for Type 2 diabetes. It is efficacious in reducing blood sugars, but shows substantial variability and risk of hypoglycemia. Basal insulin analogs have been developed in recent years to overcome these issues. Three basal insulin analogs are currently in the market in Europe. PEGylated insulin lispro is a new second generation basal insulin analog which most likely will undergo review in 2016 by the US FDA and EMA in Europe for possible approval for marketing. Phase III trials are finalized, but not yet published. Phase II studies suggest antiglycemic efficacy, possible with a preferential hepato-specific action, a low rate of hypoglycemia, minor weight loss and acceptable tolerability. The benefit risk profile needs, however, to be established. PMID- 30293493 TI - Anti-inflammatory effects of gastric bypass surgery and their association with improvement in metabolic profile. AB - Obesity is associated with chronic inflammation and metabolic disease. Bariatric surgery offers a treatment that can effectively reduce weight and improve the metabolic function. However, the effect of bariatric surgery on chronic inflammation in obesity is under-investigated. In this expert review, the authors outline the effect of Roux-en-Y gastric bypass, the most commonly performed bariatric surgery in current practice, on the markers of inflammation. They include a discussion of the relationship between inflammation and weight loss after surgery, the interaction between these markers and metabolic disease, and the effect on adipose tissue inflammation. They also briefly explore the role of glucagon-like-peptide 1 in remediating inflammation and the changes in gut microbiota after Roux-en-Y gastric bypass, and how they may be important in inflammation. PMID- 30293494 TI - Polemics of pioglitazone: an appraisal in 2015. AB - Pioglitazone is an inexpensive and effective oral drug for the treatment of Type 2 diabetes. It addresses insulin resistance, one of the core pathophysiological defects in Type 2 diabetes, at both the adipose tissue and skeletal muscle level. As a majority of Type 2 diabetics classically exhibit higher insulin resistance, pioglitazone may strike exactly at the Achilles heel in this core pathogenesis. However, with the emerging association of bladder cancer with pioglitazone, French and German regulators were the first to ban or restrict pioglitazone use in 2011. The Indian regulators also suspended pioglitazone, although this ban was revoked within a month. Recently, a 10-year longitudinal study commissioned by US FDA found no association between bladder cancer and pioglitazone. Nevertheless, this controversy created a huge outcry in the medical fraternity. This review article is an overview of the development of this topic and an attempt to provide perspective on this contemporary issue. PMID- 30293495 TI - Reducing diabetic limb amputations in developing countries. AB - Among all the diabetes complications, diabetic foot complications are associated with the highest morbidity and mortality. Across the globe, 40-60% of all lower extremity non-traumatic amputations are performed in patients with diabetes. The most important intervention in reducing diabetic limb amputation in developing countries is the education of patients about proper limb care. Cost-effective education should be targeted for both healthcare workers and patients. One of these programs is the Step by Step Foot Project, which was piloted and carried out in Tanzania and India. In this review, the author explores the feasible ways of reducing diabetic limb amputation which can be achieved through a trained diabetes workforce working in an effective system of care that focuses on the education of both the healthcare provider and the patient. PMID- 30293496 TI - Guiding diabetes screening and prevention: rationale, recommendations and remaining challenges. AB - Advances made in diabetes management are not sufficient to reduce morbidity, mortality and cost without making prevention efforts at various levels imperative for substantial impact. Research has demonstrated the efficacy of lifestyle intervention and medications in preventing type 2 diabetes among diverse high risk groups commonly identified with oral glucose tolerance testing. Efficacy, sustainability and safety data are most comprehensive for lifestyle and metformin, with other medications also demonstrating efficacy and potential in the pharmacoprevention of diabetes. Subsequent implementation studies have demonstrated feasibility of lifestyle intervention programs at health centers, communities, and at local and national government levels. Challenges remain in widespread translation and reaching and engaging at-risk individuals and populations. PMID- 30293497 TI - Utility of sentinel lymph node biopsy for thyroid cancer: a comprehensive review. AB - Sentinel lymph node biopsy (SLNB) is a minimally invasive lymphatic mapping technique, used to identify lymph node micrometastases and stage multiple cancer types. Despite the performance of SLNB for thyroid cancer having been under study since 1998, its role has remained controversial. The objective of this review is to summarize current research reporting on SLNB for thyroid cancer, focusing on recent studies of its application to differentiated thyroid cancer. The technique and potential benefits of SLNB are reviewed with regards to its ability to identify lymph node metastases, aid in cancer prognostication, and direct surgical and medical treatment. PMID- 30293498 TI - Linagliptin/metformin HCl (fixed combination therapy) for the treatment of Type 2 diabetes mellitus. AB - By the year 2030, diabetes mellitus will globally become the seventh leading cause of death. Currently, 382 million individuals worldwide have diabetes mellitus, with 80% residing in low- and middle-income countries. At present, Type 2 diabetes mellitus (T2DM) accounts for 85-95% of the diabetes burden in high income countries. Alarmingly, this figure may be higher in the low- and middle income nations. In an effort to combat this silent but deadly disease, pharmaceutical manufacturers have developed a host of different agents, each targeting a specific biochemical pathway. Among the most recent additions to this armament is linagliptin/metformin HCl, a fixed combination therapy compound manufactured by Boehringer Ingelheim. This novel formulation combines metformin, an insulin sensitizer, with linagliptin, a dipeptidyl peptidase-4 enzyme inhibitor. This review will discuss the pharmacokinetic properties of this molecule, assess clinical efficacy and gauge its place in the treatment algorithm for T2DM.

PMID- 30293500 TI - Local recurrence of papillary thyroid cancer. AB - Management of advanced papillary thyroid cancer (PTC >10 mm) is changing its focus. Mortality was the main outcome measure for patients treated before the 90s. In the past two decades, however, most patients diagnosed with PTC belong to the very low risk of death group. On the other hand, local recurrence of PTC remains a clinical problem, with rates up to 25% depending on the presence of nodal metastasis, tumor diameter, and the skill of the surgeon to completely remove the primary tumor and the associated lymph node metastasis at first-time thyroidectomy. After optimized surgery (total thyroidectomy plus central neck dissection), radioiodine ablation has very little influence on lymph node recurrence that now presents mostly as lateral neck node metastasis that was overlooked or incompletely resected at the time of initial surgery. PMID- 30293501 TI - Feasibility of Motivational Interviewing and Physical Activity Counseling Sessions for Improving Physical Activity Self-Management for Latina Women Either at Risk for or Diagnosed With Type 2 Diabetes Mellitus. AB - INTRODUCTION: Latinas have a greater chance of dying from diabetes than non Latina Whites. As a population group, the literature has shown that Latinas do not meet physical activity (PA) guidelines. Motivational interviewing (MI) is a patient-centered counseling method that promotes self-efficacy for behavior change. The purpose of the study was to examine the feasibility of using MI/PA counseling for self-management of type 2 diabetes mellitus with Latinas. METHODS: Latinas ( n = 12) were recruited from an occupational program in Southern California. Two MI and PA sessions were conducted over 2 months. Feasibility measures included recruitment, retention, protocol adherence, and attrition. Impact outcomes included PA, PA stage of change, and waist circumference. RESULTS: Participants attended all sessions and completed all questionnaires. Half progressed into a later stage of change for PA. DISCUSSION: Results suggest MI and PA counseling is feasible for improving PA with Latinas at risk/diagnosed with type 2 diabetes mellitus. PMID- 30293502 TI - Benefits of combining prevalent and incident cohorts: An application to myotonic dystrophy. AB - It is frequently of interest to estimate the time that individuals survive with a disease, that is, to estimate the time between disease onset and occurrence of a clinical endpoint such as death. Epidemiologic survival data are commonly collected from either an incident cohort, whose members' disease onset occurs after the study baseline date, or from a cohort with prevalent disease that is followed forward in time. Incident cohort survival data are limited by study termination, while prevalent cohort data provide biased (left-truncated) survival data. In this article, we investigate the advantages of a study design featuring simultaneous follow-up of prevalent and incident cohorts to the estimation of the survivor function. Our analyses are supported by simulations and illustrated using data on survival after myotonic dystrophy diagnosis from the United Kingdom Clinical Practice Research Datalink (CPRD). We demonstrate that the NPMLE using combined incident and prevalent cohort data estimates the true survivor function very well, even for moderate sample sizes, and ameliorates the disadvantages of using a purely incident or prevalent cohort. PMID- 30293503 TI - Dental age assessment on panoramic radiographs: Comparison between two generations of young Finnish subjects. AB - Objective To analyse the accuracy of a meta-analysis-based dental age assessment (DAA) method in Finnish paediatric patients and to compare the dental development between two generations of Finnish children. Methods Panoramic radiographs of Finnish Caucasian healthy children from two generations (early: born 1981-1984; subsequent: born 1996-2008) were analysed. All developing teeth on the left maxilla and mandible as well as the third permanent molars were analysed following Demirjian's classification. For each patient, dental age was calculated and compared with chronological age. Dental maturation patterns between the two groups were compared. Results The study included 200 Finnish Caucasian healthy children from two generations (early: aged 7-13 years; subsequent: aged 6-15 years). In the early generation, DAA underestimated the chronological age by a mean of 3.15 years. The underestimation was only 0.11 years in patients < 10 years, but 3.86 years in patients >= 10 years. In the subsequent generation, the dental age was overestimated by a mean of 0.34 years; by 0.40 years in patients < 10 years and by 0.08 years in patients >= 10 years. Conclusions The present DAA method is applicable to current Finnish children. Differences in dental development between two generations of Finnish children were detected.

It describes the longstanding and successful experience of this socialist country, developed in adverse and complex circumstances. The Cuban case remains one of the leading examples of a comprehensive governmental approach toward population health and well-being. The analysis underscores the essential role of continued political will toward population health. PMID- 30293506 TI - Osteoporosis in pituitary diseases: lessons for the clinic. AB - Osteoporosis is a systemic disease characterized by bone mass and density loss leading to fragility fractures. Osteoporosis due to endocrine disorders is an example of secondary osteoporosis. The harmful effects on bones are common in patients harboring pituitary tumors (acromegaly, prolactinoma, Cushing's disease) and suffering from hypopituitarism. Increased fracture risk and high healthcare costs of fractured patients are their consequences. The coexistence of some of these disorders and hypogonadism results in severe osteoporosis. The influence of the certain diseases, their activity and therapy and accompanying hypogonadism on bone turnover, bone mineral density and fracture incidence is presented. PMID- 30293507 TI - Review of growth hormone therapy in adolescents and young adults with Prader Willi syndrome. AB - Consensus guidelines from the Growth Hormone Research Society Workshop recommend growth hormone therapy in all children with genetically confirmed Prader-Willi syndrome (PWS) in combination with dietary, lifestyle and environmental interventions. As yet, however, there are limited published data regarding the use of growth hormone therapy in adolescents and young adults with PWS. This review focuses on the advantages and disadvantages of growth hormone therapy in this particular group. The risk of complications, challenges with consent for therapy, the need for contraception in females with PWS and the appropriate monitoring required are all factors which must be carefully considered in this challenging patient group. Transition from paediatric to adult services can be difficult for most adolescents, but especially so for PWS adolescents and should be undertaken under the care of experienced paediatric and adult endocrinologists and a multidisciplinary team approach. Further research is, however, still required in the management of PWS patients during adolescence. PMID- 30293508 TI - Potential novel therapeutic strategies from understanding adipocyte transdifferentiation mechanisms. AB - Brown adipocytes are located in discrete anatomical locations in both small mammals and in humans. 'Brown-like' adipocytes, also known as brite (brown in white) or beige adipocytes are found interspersed among white adipocytes in several fat depots. From a functional point of view, the activity of brown and brite cells is similar, that is, heat production mediated by uncoupling protein 1. The morphology and expression of 'thermogenic' genes is also very similar in these two cell types. The origin of brite adipocytes is under intense investigation because enhancing their presence and activity has the potential to promote a healthy metabolic profile. Transdifferentiation mechanisms as well as de novo recruitment have been investigated. The characterization of the mechanisms involved in the recruitment and activation of brown/brite adipocytes in adult humans, could open the avenue for promising therapeutic strategies to curb metabolic diseases. PMID- 30293509 TI - Oral antidiabetic agents in gestational diabetes: a narrative review of current evidence. AB - Gestational diabetes mellitus (GDM) classically occurs when maternal glucose metabolism is unable to compensate the progressive development of insulin resistance that arises from the continuously rising diabetogenic placental hormones. Although most women can be treated satisfactorily with diet alone, some require more intensive treatment. Insulin has been the most reliable treatment strategy in GDM over several decades. Although a long time has passed since the publication of two randomized controlled trials suggesting comparable efficacy and safety of metformin and glibenclamide, international bodies have not yet approved these oral agents. However, with the consistently emerging efficacy and safety data of these two drugs in the past decade, they may perhaps open a rather new door. The aim of this narrative review is to critically evaluate the existing evidence regarding safety and efficacy of oral drugs in GDM accumulated since the first publication in year 2000, suggesting clinical equivalency of glibenclamide (glyburide). PMID- 30293510 TI - Endocrinology of bone/brain crosstalk. AB - Bone metabolism is regulated by the action of two skeletal cells: osteoblasts and osteoclasts. This process is controlled by many genetic, hormonal and lifestyle factors, but today more and more studies have allowed us to identify a neuronal regulation system termed 'bone-brain crosstalk', which highlights a direct relationship between bone tissue and the nervous system. The first documentation of an anatomic relationship between nerves and bone was made via a wood cut by Charles Estienne in Paris in 1545. His diagram demonstrated nerves entering and leaving the bones of a skeleton. Later, several studies were conducted on bone innervation and, as of today, many observations on the regulation of bone remodeling by neurons and neuropeptides that reside in the CNS have created a new research field, that is, neuroskeletal research. PMID- 30293511 TI - Colestilan for the treatment of hyperphosphatemia in chronic kidney disease patients on dialysis. AB - Chronic kidney disease in the later stages poses many treatment challenges. Hyperphosphatemia is one that is well-known and is often linked to increased cardiovascular morbidity/mortality. Currently, a number of phosphate binders are available that act to conserve serum phosphate at normal or near normal levels. However, it is the overall profile of all binders that needs to be taken into account and the risks and the potential benefits associated with each agent must be balanced when selecting a particular phosphate binder. It is known that calcium-based binders, although effective phosphate binders, may lead to hypercalcemia and/or positive calcium balance and cardiovascular calcification. One, new non-calcium phosphate binder, recently approved in Europe, is colestilan. Colestilan possesses a range of properties that may afford further advantages over simply reducing serum phosphate. This review assesses the pharmacology and clinical data of colestilan used to treat hyperphosphatemia in chronic kidney disease stage 5 patients on dialysis. The article was written based on literature searches using PubMed to find articles published on phosphate binders or colestilan over the last 10 years. PMID- 30293512 TI - An update on diabetes related skeletal fragility. AB - There are several mechanisms by which diabetes could affect bone mass and strength. These mechanisms include insulin deficiency; hyperglycemia; the accumulation of advanced glycation end products that may influence collagen characteristics; marrow adiposity and bone inflammation. Furthermore, associated diabetic complications and treatment with thaizolidinediones may also increase risk of fracturing. The following article provides its readers with an update on the latest information pertaining to diabetes related bone skeletal fragility. In the authors' opinion, future studies are needed in order to clarify the impact of different aspects of diabetes metabolism, glycemic control, and specific treatments for diabetes on bone. Given that dual energy x-ray absorptiometry is a poor predictor of bone morbidity in this group of patients, there is a need to explore novel approaches for assessing bone quality. It is important that we develop a better understanding of how diabetes affects bone in order to improve our ability to protect bone health and prevent fractures in the growing population of adults with diabetes. PMID- 30293513 TI - Cardiovascular risk profiles in Type 2 diabetes and the impact of geographical setting. AB - Cardiovascular (CV) disease is a leading morbidity and mortality in Type 2 diabetes (T2DM). Previous studies have shown geographic differences in the prevalence of CV and renal diseases. A literature review of longitudinal (>=5 years) studies including >=1000 T2DM patients and reporting CV endpoints was performed to compare risk profiles. Key differences between geographies included a relatively higher prevalence of microalbuminuria in East Asian relative to North American and European patients, which in turn is an important CV risk factor. Patients from East Asia also have a relatively higher incidence of stroke and lower incidence of coronary heart disease. Overall, there are differences in CV risk in T2DM patients between different regions and that long-term studies from Africa, the Middle East and Latin America are lacking. PMID- 30293514 TI - Improving diabetes diagnosis and management in myocardial infarction patients: overcoming clinical inertia. AB - Diabetes is underdiagnosed and undertreated among acute myocardial infarction (AMI) patients. The early diagnosis and treatment of diabetes during AMI facilitates improved risk stratification, use of appropriate revascularization strategies and secondary prevention medications, and timely initiation of glycemic therapy. Accurate diagnostic methods, such as hemoglobin A1c, should be evaluated for hospitalized AMI patients. In addition, efforts to improve the uptake of diabetes screening and management in the hospitalized setting should occur. Possible actions include the use of clinical information systems to generate physician reminders for diabetes detection and management, audit and feedback programs, and professional society initiatives to address diabetes screening and therapy initiation through clinical guidelines and performance measures. Through the application of both these and other efforts listed in the manuscript, the rates of undiagnosed and undertreated diabetes among AMI patients can be significantly reduced, which would lead to an improvement in both diabetic and cardiovascular outcomes. PMID- 30293515 TI - The neuropeptide Y-ergic system: potential therapeutic target against bone loss with obesity treatments. AB - Obesity is no longer considered to provide protection against osteoporosis. Moreover, treatments for obesity are now suspected of reducing bone mass. With the escalating incidence of obesity, combined with increases in the frequency, duration and intensity of interventions used to combat it, we face a potential increase in health burden due to osteoporotic fractures. The neuropeptide Y-ergic system offers a potential target for the prevention and anabolic treatment of bone loss in obesity, due to its dual role in the regulation of energy homeostasis and bone mass. Although the strongest stimulation of bone mass by this system appears to occur via indirect hypothalamic pathways involving Y2 receptors (one of the five types of receptors for neuropeptide Y), Y1 receptors on osteoblasts (bone-forming cells) induce direct effects to enhance bone mass. This latter pathway may offer a suitable target for anti-osteoporotic treatment while also minimizing the risk of adverse side effects. PMID- 30293516 TI - Synthesizing Qualitative Data Sets to Improve the Design of Trials and Complex Health Interventions: A Worked Example. AB - Qualitative researchers are increasingly reanalyzing and synthesizing data sets from different studies, and this method has now been used across trials to inform trial methodology and delivery. Despite this work, however, limited guidance exists about how this method should be employed. This article details an example in which interview data collected during three primary care depression trials were brought together to explore trial participants' study and treatment journeys. It details the process involved and the decisions made. It also presents findings from this synthesis to illustrate how this method can be used to inform the development of future trials and complex interventions, through raising questions about how researchers currently define and design treatment arms and indicating what factors may improve or hinder participants' engagement with their allocated treatment.

The patient made a complete recovery. PMID- 30293517 TI - Verbal adynamia in parkinsonian syndromes: behavioral correlates and neuroanatomical substrate. AB - Verbal adynamia (impaired language generation, as during conversation) has not been assessed systematically in parkinsonian disorders. We addressed this in patients with Parkinson's dementia, progressive supranuclear palsy and corticobasal degeneration. All disease groups showed impaired verbal fluency and sentence generation versus healthy age-matched controls, after adjusting for general linguistic and executive factors. Dopaminergic stimulation in the Parkinson's group selectively improved verbal generation versus other cognitive functions. Voxel-based morphometry identified left inferior frontal and posterior superior temporal cortical correlates of verbal generation performance. Verbal adynamia warrants further evaluation as an index of language network dysfunction and dopaminergic state in parkinsonian disorders. PMID- 30293519 TI - The small RNA, SdsR, acts as a novel type of toxin in Escherichia coli. AB - Most small noncoding RNAs (sRNAs) are known to base pair with target mRNAs and regulate mRNA stability or translation to trigger various changes in the cell metabolism of Escherichia coli. The SdsR sRNA is expressed specifically during the stationary phase and represses tolC and mutS expression. However, it was not previously known whether the growth-phase-dependent regulation of SdsR is important for cell growth. Here, we ectopically expressed SdsR during the exponential phase and examined cell growth and survival. We found that ectopic expression of SdsR led to a significant and Hfq-dependent cell death with accompanying cell filamentation. This SdsR-driven cell death was alleviated by overexpression of RyeA, an sRNA transcribed on the opposite DNA strand, suggesting that SdsR/RyeA is a novel type of toxin-antitoxin (T/A) system in which both the toxin and the antitoxin are sRNAs. We defined the minimal region required for the SdsR-driven cell death. We also performed RNA-seq analysis and identified 209 genes whose expression levels were altered by more than two-fold following pulse expression of ectopic SdsR at exponential phase. Finally, we found that that the observed SdsR-driven cell death was mainly caused by the SdsR mediated repression of yhcB, which encodes an inner membrane protein. PMID- 30293520 TI - Lexical prediction in the aging brain: The effects of predictiveness and congruency on the N400 ERP component. AB - Although the N400 ERP component has been extensively studied in younger adults, the underlying mechanisms are still unclear. In older adults, N400 ERP studies have shown less efficient use of context compared to younger adults. Here, we asked whether the mechanisms underlying the N400 effect are the same in terms of predictiveness and congruency in younger and older adults. We used a simple picture-word matching task in which we crossed predictiveness and congruency. Our results indicate a three-way interaction between predictiveness, congruency, and age, in that, younger adults showed an N400 effect only in strongly constrained conditions; whereas, older adults showed an effect in both strongly- and weakly constrained conditions. This interaction was not modulated by language experience or cognitive decline. Our results support either two separate mechanisms (lexical access and integration) that run in parallel and are modulated by age or a common prediction error mechanism that changes with age. PMID- 30293521 TI - A Rigorous Approach to Large-Scale Elicitation and Analysis of Patient Narratives. AB - Patient narratives have emerged as promising vehicles for making health care more responsive by helping clinicians to better understand their patients' expectations, perceptions, or concerns and encouraging consumers to engage with information about quality. A growing number of websites incorporate patients' comments. But existing comments have fragmentary content, fail to represent less vocal patients, and can be manipulated to "manage" providers' reputations. In this article, we offer the first empirical test of the proposition that patient narratives can be elicited rigorously and reliably using a five-question protocol that can be incorporated into large-scale patient experience surveys. We tested whether elicited narratives about outpatient care are complete (report all facets of patient experience), balanced (convey an accurate mix of positive and negative events), meaningful (have a coherent storyline), and representative (draw fulsome narratives from all relevant subsets of patients). The tested protocol is strong on balance and representativeness, more mixed on completeness and meaningfulness. PMID- 30293522 TI - Patterns of recognition of Arabic consonants by non-native children with cochlear implants and normal hearing. AB - OBJECTIVE: This study examined the patterns of recognition of Arabic consonants, via information transmission analysis for phonological features, in a group of Malay children with normal hearing (NH) and cochlear implants (CI). METHOD: A total of 336 and 616 acoustic tokens were collected from six CI and 11 NH Malay children, respectively. The groups were matched for hearing age and duration of exposure to Arabic sounds. All the 28 Arabic consonants in the form of consonant vowel /a/ were presented randomly twice via a loudspeaker at approximately 65 dB SPL. The participants were asked to repeat verbally the stimulus heard in each presentation. RESULTS: Within the native Malay perceptual space, the two groups responded differently to the Arabic consonants. The dispersed uncategorized assimilation in the CI group was distinct in the confusion matrix (CM), as compared to the NH children. Consonants /h/, /t?/, /s?/ and /?/ were difficult for the CI children, while the most accurate item was /k/ (84%). The CI group transmitted significantly reduced information, especially for place feature transmission, then the NH group (p < 0.001). Significant interactions between place-hearing status and manner-hearing status were also obtained, suggesting there were information transmission differences in the pattern of consonants recognition between the study groups. CONCLUSION: CI and NH Malay children may be using different acoustic cues to recognize Arabic sounds, which contribute to the different assimilation categories' patterns within the Malay perceptual space. PMID- 30293524 TI - Pacing profile in the main international open-water swimming competitions. AB - PURPOSE: Different aspects of pacing in endurance events have been investigated, however, there are very limited information on pacing strategies during open water swimming. The aim was to describe and compare the pacing profile used by male and female open-water swimmers (OW-swimmers) during the 5-, 10- and 25 km races in the main international competitions. METHODS: A total of 438 performances were analysed for 5 km, 579 for 10 km and 189 for 25 km, from 2012 to 2017. Swimmers were divided into four groups based on finishing time. G1 whose finishing times were within 0.5% of the winner's time, G2 between 0.51% and 1% slower than winner's time; G3 between 1.1% and 2% slower than winner's time; G4 over 2% of winner's time. Kolmogorov-Smirnov test was used to verify the normal distribution of data and repeated measures ANOVA was performed. RESULTS: G1 adopted a negative pacing and significantly increased the speed in the last split compared with the other groups during the 5-, 10- and 25-km races in both males and females (p < .001). During the 5- and 10-km race, the last split speed of G1 was significantly faster compared to the other groups in both males and females (p < .05). CONCLUSIONS: OW-swimmers that used a conservative approach remaining in G1 until the finish of the race, increase the possibility to win a medal in the main international competitions. PMID- 30293523 TI - Are professional young rugby league players eating enough? Energy intake, expenditure and balance during a pre-season. AB - Due to the unique energetic demands of professional young collision sport athletes, accurate assessment of energy balance is required. Consequently, this is the first study to simultaneously investigate the energy intake, expenditure and balance of professional young rugby league players across a pre-season period. The total energy expenditure of six professional young male rugby league players was measured via doubly labelled water over a fourteen-day assessment period. Resting metabolic rate was measured and physical activity level calculated. Dietary intake was reported via Snap-N-Send over a non-consecutive ten-day assessment period, alongside changes in fasted body mass and hydration status. Accordingly, energy balance was inferred. The mean (standard deviation) difference between total energy intake (16.73 (1.32) MJ.day-1) and total energy expenditure (18.36 (3.05) MJ.day-1) measured over the non-consecutive ten-day period was unclear (-1.63 (1.73) MJ.day-1; ES = 0.91 +/- 1.28; p = 0.221). This corresponded in a most likely trivial decrease in body mass (-0.65 (0.78) kg; ES = 0.04 +/- 0.03; p = 0.097). Resting metabolic rate and physical activity level across the fourteen-day pre-season period was 11.20 (2.16) MJ.day-1 and 1.7 (0.2), respectively. For the first time, this study utilises gold standard assessment techniques to elucidate the distinctly large energy expenditures of professional young rugby league players across a pre-season period, emphasising a requirement for equally large energy intakes to achieve targeted body mass and composition adaptations. Accordingly, it is imperative that practitioners regularly assess the energy balance of professional young collision-sport athletes to ensure their unique energetic requirements are achieved.

PMID- 30293527 TI - Age-specific response of skeletal muscle extracellular matrix to acute resistance exercise: A pilot study. AB - The extracellular matrix (ECM) plays an essential role in the development, growth and repair of skeletal muscles and serves to transmit contractile force. However, its regulation is poorly understood. This study investigates the age-specificity of the effects of acute resistance exercise on ECM gene expression. To this purpose, five young (YM, 23.8 +/- 2.2 yrs.) and 5 elderly (EM, 66.8 +/- 4.1 yrs.) men performed one session of unilateral leg press and leg extension exercises. Six hours post-exercise, biopsies were taken from the vastus lateralis muscles of both legs. A PCR array was used to profile the expression of 84 ECM-related genes, of which 6 were validated by qPCR. The PCR array found 9 and 4 ECM associated genes to be selectively altered (>1.5-fold change) in YM or EM only. Four further genes were upregulated in YM but downregulated in EM. Of the 6 genes validated on individual samples MMP9 expression increased in YM (9.7-fold) and decreased (0.2-fold) in EM. MMP15 was downregulated in EM only (0.6-fold). A significant correlation between leg extension 1 RM and changes in COL7A1 expression (rho = 0.71) suggests a potential influence of fitness levels. In conclusion, acute resistance exercise affects ECM gene expression at least partly in an age-specific manner. The altered expression of genes encoding matrix metalloproteinases (MMP3, MMP9, MMP15) highlights the role of remodelling processes in the response to an acute bout of resistance exercise. Larger studies are required to verify the age-associated differences in gene expression profiles and establish their functional implications.

PMID- 30293530 TI - Onchocerca volvulus as a risk factor for developing epilepsy in onchocerciasis endemic regions in the Democratic Republic of Congo: a case control study. AB - BACKGROUND: A high prevalence of epilepsy has been observed in onchocerciasis endemic areas in the Democratic Republic of Congo (DRC). With this study we aimed to investigate whether Onchocerca volvulus infection is a risk factor for developing epilepsy in onchocerciasis endemic regions in the DRC. METHODS: Between October and December 2015, a multi-centre case control study was performed in onchocerciasis endemic health zones (HZ) in the DRC: one study site was situated in Tshopo Province in the HZ of Wanierukula (village of Salambongo) where there had been 13 annual community distributions of treatment with ivermectin (CDTI), a second was situated in Ituri Province in the HZ of Logo (village of Draju) where ivermectin had never been distributed and in the HZ of Rethy (village of Rassia) where there had been THREE CDTI annual campaigns before the study. Individuals with unprovoked convulsive epilepsy of unknown etiology were enrolled as cases (n = 175). Randomly selected healthy members of families without epilepsy cases from the same village and age-groups and were recruited as controls (n = 170). RESULTS: Onchocerciasis associated symptoms (e.g., itching and abnormal skin) were more often present in cases compared to controls (respectively, OR = 2.63, 95% CI: 1.63-4.23, P < 0.0001 and OR = 3.23, 95% CI: 1.48-7.09, P = 0.0034). A higher number of cases was found to present with microfilariae in skin snips and with O. volvulus IgG4 antibodies in the blood compared to controls. Moreover, the microfilariae load in skin snips was 3-10 times higher in cases than controls. CONCLUSIONS: This case control study confirms that O. volvulus is a risk factor for developing epilepsy in onchocerciasis endemic regions in the DRC. PMID- 30293532 TI - The first case of thrombocytopenia, anasarca, fever, renal impairment or reticulin fibrosis, and organomegaly (TAFRO) syndrome with unilateral adrenal necrosis: a case report. AB - BACKGROUND: TAFRO syndrome, which was first reported in 2010 in Japan, is a relatively rare disease characterized by thrombocytopenia, anasarca, fever, renal impairment, reticulin fibrosis, and organomegaly. Although this disease is considered similar to multicentric Castleman disease, some of the clinical features, such as thrombocytopenia, are different from typical cases of multicentric Castleman disease. In addition, the etiology of TAFRO syndrome remains unknown and controversial. There have only been a few cases of TAFRO syndrome complicated with adrenal gland lesions, and all of them have had hemorrhagic involvement. CASE PRESENTATION: This report describes the case of a 46-year-old Asian man who presented with fever, epigastric pain, and back pain for 1 month. A computed tomographic scan revealed ascites, mild lymphadenopathy, and left adrenal necrosis without hemorrhage. A blood test showed thrombocytopenia, anemia, and elevated C-reactive protein, alkaline phosphatase, and creatinine levels. Based on the edema, severe thrombocytopenia, fever, reticulin myelofibrosis shown by bone marrow biopsy, mild lymphadenopathy, and progressive renal insufficiency, we diagnosed this patient as having TAFRO syndrome. He was successfully treated by immediate administration of glucocorticoids and tocilizumab. CONCLUSIONS: There have been no previous reports of a case of TAFRO syndrome complicated with adrenal necrosis. Because the biopsy of the left adrenal gland revealed necrosis without any evidence of hemorrhage, we concluded that the unilateral adrenal necrosis in this case was caused by either ischemia from infarction or organomegaly itself under severe hypercytokinemia. This unusual clinical course is useful for further analysis of the etiology of TAFRO syndrome. PMID- 30293531 TI - Vaccination with chemically attenuated Plasmodium falciparum asexual blood-stage parasites induces parasite-specific cellular immune responses in malaria-naive volunteers: a pilot study. AB - BACKGROUND: The continuing morbidity and mortality associated with infection with malaria parasites highlights the urgent need for a vaccine. The efficacy of sub unit vaccines tested in clinical trials in malaria-endemic areas has thus far been disappointing, sparking renewed interest in the whole parasite vaccine approach. We previously showed that a chemically attenuated whole parasite asexual blood-stage vaccine induced CD4+ T cell-dependent protection against challenge with homologous and heterologous parasites in rodent models of malaria. METHODS: In this current study, we evaluated the immunogenicity and safety of chemically attenuated asexual blood-stage Plasmodium falciparum (Pf) parasites in eight malaria-naive human volunteers. Study participants received a single dose of 3 * 107 Pf pRBC that had been treated in vitro with the cyclopropylpyrolloindole analogue, tafuramycin-A. RESULTS: We demonstrate that Pf asexual blood-stage parasites that are completely attenuated are immunogenic, safe and well tolerated in malaria-naive volunteers. Following vaccination with a single dose, species and strain transcending Plasmodium-specific T cell responses were induced in recipients. This included induction of Plasmodium-specific lymphoproliferative responses, T cells secreting the parasiticidal cytokines, IFN gamma and TNF, and CD3+CD45RO+ memory T cells. Pf-specific IgG was not detected. CONCLUSIONS: This is the first clinical study evaluating a whole parasite blood stage malaria vaccine. Following administration of a single dose of completely attenuated Pf asexual blood-stage parasites, Plasmodium-specific T cell responses were induced while Pf-specific antibodies were not detected. These results support further evaluation of this chemically attenuated vaccine in humans. TRIAL REGISTRATION: Trial registration: ACTRN12614000228684 . Registered 4 March 2014. PMID- 30293533 TI - Transmission of resistant Gram-negative bacteria to healthcare personnel gowns and gloves during care of residents in community-based nursing facilities. AB - OBJECTIVE: To estimate the risk of transmission of antibiotic-resistant Gram negative bacteria (RGNB) to gowns and gloves worn by healthcare personnel (HCP) when providing care to residents of community-based nursing facilities to identify the types of care and resident characteristics associated with transmission. DESIGN: Prospective observational study.Settings and participantsResidents and HCP from 13 community-based nursing facilities in Maryland and Michigan. METHODS: Perianal swabs were collected from residents and cultured to detect RGNB. HCP wore gowns and gloves during usual care activities, and at the end of each interaction, these were swabbed in a standardized manner. Transmission of RGNB from a colonized resident to gowns and gloves was estimated. Odds ratios (ORs) of transmission associated with type of care or resident characteristic were calculated. RESULTS: We enrolled 403 residents and their HCP in this study. Overall, 19% of enrolled residents with a perianal swab (n=399) were colonized with at least 1 RGNB. RGNB transmission to either gloves or gowns occurred during 11% of the 584 interactions. Showering the resident, hygiene or toilet assistance, and wound dressing changes were associated with a high risk of transmission. Glucose monitoring and assistance with feeding or medication were associated with a low risk of transmission. Residents with a pressure ulcer were 3 times more likely to transmit RGNB than residents without one (OR, 3.3; 95% confidence interval [CI], 1.0-11.1). CONCLUSIONS: Gown and glove use in community nursing facilities should be prioritized for certain residents and care interactions that are deemed a high risk for transmission. PMID- 30293534 TI - Temporal dynamics of Middle East respiratory syndrome coronavirus in the Arabian Peninsula, 2012-2017. AB - Middle East respiratory syndrome coronavirus (MERS-CoV) remains a notable disease and poses a significant threat to global public health. The Arabian Peninsula is considered a major global epicentre for the disease and the virus has crossed regional and continental boundaries since 2012. In this study, we focused on exploring the temporal dynamics of MERS-CoV in human populations in the Arabian Peninsula between 2012 and 2017, using publicly available data on case counts and combining two analytical methods. Disease progression was assessed by quantifying the time-dependent reproductive number (TD-Rs), while case series temporal pattern was modelled using the AutoRegressive Integrated Moving Average (ARIMA). We accounted for geographical variability between three major affected regions in Saudi Arabia including Eastern Province, Riyadh and Makkah. In Saudi Arabia, the epidemic size was large with TD-Rs >1, indicating significant spread until 2017. In both Makkah and Riyadh regions, the epidemic progression reached its peak in April 2014 (TD-Rs > 7), during the highest incidence period of MERS-CoV cases. In Eastern Province, one unique super-spreading event (TD-R > 10) was identified in May 2013, which comprised of the most notable cases of human-to-human transmission. Best-fitting ARIMA model inferred statistically significant biannual seasonality in Riyadh region, a region characterised by heavy seasonal camel-related activities. However, no statistical evidence of seasonality was identified in Eastern Province and Makkah. Instead, both areas were marked by an endemic pattern of cases with sporadic outbreaks. Our study suggested new insights into the epidemiology of the virus, including inferences about epidemic progression and evidence for seasonality. Despite the inherent limitations of the available data, our conclusions provide further guidance to currently implement risk-based surveillance in high-risk populations and, subsequently, improve related interventions strategies against the epidemic at country and regional levels.

AB - Mycobacterium ulcerans is recognised as the third most common mycobacterial infection worldwide. It causes necrotising infections of skin and soft tissue and is classified as a neglected tropical disease by the World Health Organization (WHO). However, despite extensive research, the environmental reservoir of the organism and mode of transmission of the infection to humans remain unknown. This limits the ability to design and implement public health interventions to effectively and consistently prevent the spread and reduce the incidence of this disease. In recent years, the epidemiology of the disease has changed. In most endemic regions of the world, the number of cases reported to the WHO are reducing, with a 64% reduction in cases reported worldwide in the last 9 years. Conversely, in a smaller number of countries including Australia and Nigeria, reported cases are increasing at a rapid rate, new endemic areas continue to appear, and in Australia cases are becoming more severe. The reasons for this changing epidemiology are unknown. We review the epidemiology of M. ulcerans disease worldwide, and document recent changes. We also outline and discuss the current state of knowledge on the ecology of M. ulcerans, possible transmission mechanisms to humans and what may be enabling the spread of M. ulcerans into new endemic areas.

While Lam et al. (2018) have now provided the recommended quality control metrics for their paper, problems remain. Specifically, Lam et al. (2018) do not dispute that the results of their multi-trait analysis of genome-wide association study (MTAG) analysis has produced a phenotype with a genetic correlation of one with three measures of education, but do claim the associations found are specific to the trait of cognitive ability. In this brief paper, it is empirically demonstrated that the phenotype derived by Lam et al. (2017) is more genetically similar to education than cognitive ability. In addition, it is shown that of the genome-wide significant loci identified by Lam et al. (2017) are loci that are associated with education rather than with cognitive ability. PMID- 30293538 TI - Maternal antenatal daytime sleepiness and child neuropsychiatric and neurocognitive development. AB - BACKGROUND: The prevalence of sleep problems among pregnant women is over 50%, and daytime sleepiness is among the most common sleep problems. Previous studies have associated antenatal sleep problems with adverse maternal health and neonatal outcomes, but the consequences of antenatal sleep problems and particularly daytime sleepiness on child psychological development have not been assessed prospectively. METHODS: In this prospective cohort study including 111 mother-child dyads, we examined the associations of maternal daytime sleepiness during pregnancy, assessed at 17 and 28 weeks of gestation using the Epworth Sleepiness Scale, with child neuropsychiatric problems and neuropsychological development, assessed with mother-rated questionnaires and individually administered neuropsychological tests, at child age 2.6-5.7 years (mean = 4.3 years). RESULTS: Independently of sociodemographic and perinatal covariates and maternal depressive and anxiety symptoms during and/or after pregnancy, maternal antenatal daytime sleepiness was associated with increased total [unstandardized regression coefficient (B) = 0.25 standard deviation (s.d.) units; 95% confidence interval (CI) 0.01-0.48] and internalizing (B = 0.25 s.d.s: 95% CI 0.01-0.49) psychiatric problems and ADHD symptoms (B = 0.27 s.d.s: 95% CI 0.04-0.50) in children, and with poorer executive function, particularly in the areas of attention, working memory and inhibitory control (B = -0.39 s.d.s: 95% CI -0.69 to -0.10). CONCLUSIONS: Maternal antenatal daytime sleepiness carries adverse consequences for offspring psychological development. The assessment of sleep problems may be an important addition to standard antenatal care. PMID- 30293539 TI - The limitations of equivalence and non-inferiority trials. AB - Equivalence and non-inferiority trials are becoming more and more popular. Typically, they compare the effects of a treatment of interest with the current gold-standard treatment as the comparator. However, for this approach, the definition of equivalence or non-inferiority margins (NIM) is crucial, and no clear rules for their definition exist. We criticized the practice of these trials of being over-inflationary in favor of (erroneous) equivalence, and we outlined our critique with some study examples comparing psychodynamic treatments with current first-line treatments for mental disorders. Here we answer to a commentary of Leichsenring et al. to our paper. Although focusing on our commentary, these authors are less arguing against our conclusions, but they address issues of study conduct, and lack of appreciation of our examples. However, the crucial question is: What is the risk of erroneous equivalence conclusions that we want to accept as responsible clinicians and scientists? We conclude that the scientific community has to define better and clearer criteria for NIMs. We do not believe that it is ethically justifiable to recommend a treatment that is 10 or 20% less effective than the current gold standard interventions. PMID- 30293540 TI - New product, old problem(s): multistate outbreak of Salmonella Paratyphi B variant L(+) tartrate(+) infections linked to raw sprouted nut butters, October 2015. AB - A cluster of Salmonella Paratyphi B variant L(+) tartrate(+) infections with indistinguishable pulsed-field gel electrophoresis patterns was detected in October 2015. Interviews initially identified nut butters, kale, kombucha, chia seeds and nutrition bars as common exposures. Epidemiologic, environmental and traceback investigations were conducted. Thirteen ill people infected with the outbreak strain were identified in 10 states with illness onset during 18 July-22 November 2015. Eight of 10 (80%) ill people reported eating Brand A raw sprouted nut butters. Brand A conducted a voluntary recall. Raw sprouted nut butters are a novel outbreak vehicle, though contaminated raw nuts, nut butters and sprouted seeds have all caused outbreaks previously. Firms producing raw sprouted products, including nut butters, should consider a kill step to reduce the risk of contamination. People at greater risk for foodborne illness may wish to consider avoiding raw products containing raw sprouted ingredients. PMID- 30293541 TI - Age, Gender and Mechanism of Injury Interactions in Post-Concussion Syndrome. AB - BACKGROUND: Certain factors such as age and gender seem to affect the risk of developing post-concussion syndrome (PCS). We assessed the interactions between age, gender, concussion history and mechanism of injury in PCS patients so that a better understanding could guide the development of targeted prevention strategies. METHODS: Demographic data including age, gender, concussion mechanism of injury and concussion history were collected from (1) a prospective study evaluating PCS biomarkers and (2) a retrospective chart review of PCS patients. A total of 437 PCS patients who were assessed at the Canadian Concussion Centre or Toronto Western Hospital, Toronto, ON, were included. RESULTS: Overall, there were more men with PCS; however, a greater percentage of women had PCS after a single concussion. The results showed that age, gender and concussion history are conditionally dependent on the mechanism of injury, and independent of one another. The relative frequency of having PCS was greater in the following instances: (1) being a woman and having had concussion from a fall or motor vehicle collision (MVC), (2) being older and having had concussion from a fall or MVC or (3) having a single concussion with cause being MVC or fall. CONCLUSION: In patients with PCS, age and gender interact with the mechanism of injury to influence the risk of concussion. Targeted prevention strategies may be essential to prevent injuries leading to PCS. PMID- 30293542 TI - Dietary starch and rhubarb supplement increase ruminal dissolved hydrogen without altering rumen fermentation and methane emissions in goats. AB - Hydrogen is an important intermediate that is produced during carbohydrate fermentation to volatile fatty acid and utilized by methanogens to produce methane in the rumen. Ruminal volatile fatty acid and dissolved methane concentrations are more than 500 times greater than dissolved hydrogen concentration. Therefore, we hypothesized that dissolved hydrogen might have a higher sensitivity in response to dietary changes compared with volatile fatty acid and dissolved methane. Using goats, we investigated the effects of increasing dietary starch content (maize replaced with wheat bran) and supplementing with rhubarb rhizomes and roots on the relationships among dissolved hydrogen, dissolved methane and other fermentation end products. The study was conducted in a replicated 4*4 Latin square with a 2*2 factorial arrangement of four treatments: two starch levels (220 v. 320 g/kg dry matter (DM)), without and with rhubarb supplement (0% v. 2.8% of total mixed ration). Increased dietary starch and rhubarb supplementation did not alter volatile fatty acid concentrations or methane emissions in terms of g/day, g/g DM intake and g/g organic matter digested. However, goats fed the high-starch diet had greater dissolved hydrogen (P=0.005) and relative abundance of Selenomonas ruminantium (P<0.01), and lower (P=0.02) copy number of protozoa than those fed the low starch diet. Rhubarb increased ruminal dissolved H2 (P=0.03) and total volatile fatty acid concentration (P<0.001), but decreased copies of bacteria (P=0.002). In conclusion, dissolved hydrogen appears to be more sensitive to dietary changes with starch content and rhubarb supplementation, when compared with volatile fatty acid concentrations and methane production. PMID- 30293543 TI - Multilocus sequencing-based evolutionary analysis of 52 strains of Burkholderia pseudomallei in Hainan, China. AB - Previously, we reported a phylogenetic study of 98 Burkholderia pseudomallei clinical isolates from Hainan, China. Here, we update the B. pseudomallei strain library with 52 strains from newly identified cases dating from 2014 to 2017, analysed by multilocus sequence typing. Twenty-two sequence types (STs) were identified from the 52 cases, illustrating high genetic diversity; five of them (ST1480, ST1481, ST1482, ST1483 and ST1484) were novel. ST46, ST50 and ST58 predominated (34.6%) as was the case in the previous study (35.7%). An e-BURST map of the ST profiles of the two collections of isolates showed their genetic foundation to be largely unchanged. Neighbour-joining tree analysis was suggestive of a close phylogenetic relationship between the novel STs from this series and those first reported from Hainan (ST1105, ST1099, ST55 and ST1095). Moreover, the two novel STs (1481 and 1483) showed close similarity to ST58 which originated in Thailand indicating a close relationship between B. pseudomallei strains from both countries. The previously described allele profiles gmhD-36 and lepA-68 were found for the first time in our strain collections. Our study emphasises the importance of monitoring the epidemiological status and evolutionary trends of B. pseudomallei in China. PMID- 30293544 TI - Effects of Virtual Reality Simulation on Worker Emergency Evacuation of Neonates. AB - OBJECTIVE: This study examined differences in learning outcomes among newborn intensive care unit (NICU) workers who underwent virtual reality simulation (VRS) emergency evacuation training versus those who received web-based clinical updates (CU). Learning outcomes included a) knowledge gained, b) confidence with evacuation, and c) performance in a live evacuation exercise. METHODS: A longitudinal, mixed-method, quasi-experimental design was implemented utilizing a sample of NICU workers randomly assigned to VRS training or CUs. Four VRS scenarios were created that augmented neonate evacuation training materials. Learning was measured using cognitive assessments, self-efficacy questionnaire (baseline, 0, 4, 8, 12 months), and performance in a live drill (baseline, 12 months). Data were collected following training and analyzed using mixed model analysis. Focus groups captured VRS participant experiences. RESULTS: The VRS and CU groups did not statistically differ based upon the scores on the Cognitive Assessment or perceived self-efficacy. The virtual reality group performance in the live exercise was statistically (P<.0001) and clinically (effect size of 1.71) better than that of the CU group. CONCLUSIONS: Training using VRS is effective in promoting positive performance outcomes and should be included as a method for disaster training. VRS can allow an organization to train, test, and identify gaps in current emergency operation plans. In the unique case of disasters, which are low-volume and high-risk events, the participant can have access to an environment without endangering themselves or clients.

PMID- 30293545 TI - Human Umbilical Cord Blood Plasma Alleviates Age-related Olfactory Dysfunction by Attenuating Peripheral TNF-alpha expression. AB - Social requirements are needed for living in an aging society and individual longevity. Among them, improved health and medical cares, appropriate for an aging society are strongly demanded. Human cord blood-derived plasma (hUCP) has recently emerged for its unique anti-aging effects. In this study, we investigated brain rejuvenation, particularly olfactory function, that could be achieved by a systemic administration of young blood and its underlying mechanisms. Older than 24-month-old mice were used as an aged group and administered with intravenous injection of hUCP repetitively, eight times. Anti aging effect of hUCP on olfactory function was evaluated by buried food finding test. To investigate the mode of action of hUCP, brain, serum and spleen of mice were collected for further ex vivo analyses. Systemic injection of hUCP improved aging-associated olfactory deficits, reducing time for finding food. In the brain, although an infiltration of activated microglia and its expression of cathepsin S remarkably decreased, significant changes of proinflammatory factors were not detected. Conversely, peripheral immune balance distinctly switched from predominance of Type 1 helper T (Th1) cells to alternative regulatory T cells (Tregs). These findings indicate that systemic administration of hUCP attenuates age-related neuroinflammation and subsequent olfactory dysfunction by modulating peripheral immune balance toward Treg cells, suggesting another therapeutic function and mechanism of hUCP administration. PMID- 30293546 TI - Interferon-gamma-mediated Secretion of Tryptophanyl-tRNA Synthetases Has a Role in Protection of Human Umbilical Cord Blood-derived Mesenchymal Stem Cells Against Experimental Colitis. AB - Mesenchymal stem cells (MSCs) are multipotent adult stem cells that present immunosuppressive effects in experimental and clinical trials targeting various rare diseases including inflammatory bowel disease (IBD). In addition, recent studies have reported tryptophanyl-tRNA synthetase (WRS) possess uncanonical roles such as angiostatic and anti-inflammatory effects. However, little is known about the function of WRS in MSC-based therapy. In this study, we investigated if a novel factor, WRS, secreted from MSCs has a role in amelioration of IBD symptoms and determined a specific mechanism underlying MSC therapy. Experimental colitis was induced by administration of 3% DSS solution to 8-week-old mice and human umbilical cord blood-derived MSCs (hUCB-MSCs) were injected intraperitoneally. Secretion of WRS from hUCB-MSCs and direct effect of WRS on isolated CD4+ T cells was determined via in vitro experiments and hUCB-MSCs showed significant therapeutic rescue against experimental colitis. Importantly, WRS level in serum of colitis induced mice decreased and recovered by administration of MSCs. Through in vitro examination, WRS expression of hUCB-MSCs increased when cells were treated with interferon-gamma (IFN-gamma). WRS was evaluated and revealed to have a role in inhibiting activated T cells by inducing apoptosis. In summary, IFN-gamma-mediated secretion of WRS from MSCs has a role in suppressive effect on excessive inflammation and disease progression of IBD and brings new highlights in the immunomodulatory potency of hUCB-MSCs. PMID- 30293547 TI - Overexpression of CXCL2 inhibits cell proliferation and promotes apoptosis in hepatocellular carcinoma. AB - C-X-C motif chemokine ligand 2 (CXCL2) is a small secreted protein that exhibits a structure similar to the proangiogenic subgroup of the CXC chemokine family. Recently, accumulating evidence suggests that chemokines play a pivotal role in cancer progression and carcinogenesis. We examined the expression levels of 7 types of ELR+ CXCLs messenger RNA (mRNA) in 264 clinical samples. We found that CXCL2 expression was stably down-regulated in 94% of hepatocellular carcinoma (HCC) specimens compared with paired adjacent normal liver tissues and some HCC cell lines. Moreover, CXCL2 overexpression profoundly attenuated HCC cell proliferation and growth and induced apoptosis in vitro. In animal studies, we found that overexpressing CXCL2 by lentivirus also apparently inhibited the size and weight of subcutaneous tumours in nude mice. Furthermore, we demonstrated that CXCL2 induced HCC cell apoptosis via both nuclear and mitochondrial apoptosis pathways. Our results indicate that CXCL2 negatively regulates the cell cycle in HCC cells via the ERK1/2 signalling pathway. These results provide new insights into HCC and may ultimately lead to the discovery of innovative therapeutic approaches of HCC. PMID- 30293548 TI - Leptin stimulates IGF-1 transcription by activating AP-1 in human breast cancer cells. AB - Leptin, an adipokine regulating energy metabolism, appears to be associated with breast cancer progression. Insulin-like growth factor-1 (IGF-1) mediates the pathogenesis of breast cancer. The regulation of IGF-1 expression by leptin in breast cancer cells is unclear. Here, we found that leptin upregulates IGF-1 expression at the transcriptional level in breast cancer cells. Activating protein-1 (AP-1)-binding element within the proximal region of IGF-1 was necessary for leptin-induced IGF-1 promoter activation. Forced expression of AP-1 components, c-FOS or c-JUN, enhanced leptin-induced IGF-1 expression, while knockdown of c-FOS or c-JUN abrogated leptin responsiveness. All three MAPKs (ERK1/2, JNK1/2, and p38 MAPK) mediated leptin-induced IGF-1 expression. These results suggest that leptin contributes to breast cancer progression through the transcriptional upregulation of leptin via the MAPK pathway. PMID- 30293549 TI - Enhanced Delivery of Protein Fused to Cell Penetrating Peptides to Mammalian Cells. AB - Recent progress in cellular reprogramming technology and lineage-specific cell differentiation has provided great opportunities for translational research. Because virus-based gene delivery is not a practical reprogramming protocol, protein-based reprogramming has been receiving attention as a safe way to generate reprogrammed cells. However, the poor efficiency of the cellular uptake of reprogramming proteins is still a major obstacle. Here, we reported key factors which improve the cellular uptake of these proteins. Purified red fluorescent proteins fused with 9xLysine (dsRED-9K) as a cell penetrating peptide were efficiently delivered into the diverse primary cells. Protein delivery was improved by the addition of amodiaquine. Furthermore, purified dsRED-9K was able to penetrate all cell lineages derived from mouse embryonic stem cells efficiently. Our data may provide important insights into the design of protein based reprogramming or differentiation protocols. PMID- 30293550 TI - Functions of DEAD box RNA helicases DDX5 and DDX17 in chromatin organization and transcriptional regulation. AB - RNA helicases DDX5 and DDX17 are multitasking proteins that regulate gene expression in different biological contexts through diverse activities. Special attention has long been paid to their function as coregulators of transcription factors, providing insight about their functional association with a number of chromatin modifiers and remodelers. However, to date, the variety of described mechanisms has made it difficult to understand precisely how these proteins work at the molecular level, and the contribution of their ATPase domain to these mechanisms remains unclear as well. In light of their association with long noncoding RNAs that are key epigenetic regulators, an emerging view is that DDX5 and DDX17 may act through modulating the activity of various ribonucleoprotein complexes that could ensure their targeting to specific chromatin loci. This review will comprehensively describe the current knowledge on these different mechanisms. We will also discuss the potential roles of DDX5 and DDX17 on the 3D chromatin organization and how these could impact gene expression beyond the transcriptional and post-transcriptional levels. PMID- 30293551 TI - Cellular machinery for sensing mechanical force. AB - For mechanical force to induce changes in cellular behaviors, two main processes are inevitable; perception of the force and response to it. Perception of mechanical force by cells, or mechanosensing, requires mechanical force-induced conformational changes in mechanosensors. For this, at least one end of the mechanosensors should be anchored to relatively fixed structures, such as extracellular matrices or the cytoskeletons, while the other end should be pulled along the direction of the mechanical force. Alternatively, mechanosensors may be positioned in lipid bilayers, so that conformational changes in the embedded sensors can be induced by mechanical force-driven tension in the lipid bilayer. Responses to mechanical force by cells, or mechanotransduction, require translation of such mechanical force-induced conformational changes into biochemical signaling. For this, protein-protein interactions or enzymatic activities of mechanosensors should be modulated in response to force-induced structural changes. In the last decade, several molecules that met the required criteria of mechanosensors have been identified and proven to directly sense mechanical force. The present review introduces examples of such mechanosensors and summarizes their mechanisms of action. PMID- 30293552 TI - [Cow's milk protein allergy with skin lesions. Is it always necessary to refer to a dermatologist?] PMID- 30293553 TI - Functional Surgery for Malignant Subungual Tumors: A Case Series and Literature Review. AB - BACKGROUND AND OBJECTIVES: Amputation is the conventional treatment for malignant subungual tumors (MSUTs), namely, subungual squamous cell carcinoma (SUSCC) and subungual melanoma (SUM). Functional surgery consisting of wide local excision (WLE) of the nail unit can preserve function without modifying prognosis in such cases. We present a series of MSUTs treated with WLE of the nail unit, describe the technique, and review its indications. MATERIAL AND METHODS: Retrospective observational study of MSUTs treated with WLE of the nail unit between 2008 and 2017. The technique consisted of en bloc supraperiosteal excision of the nail unit with a margin of 5mm followed by repair with a full-thickness graft. RESULTS: Eleven MSUTs were treated in the study period: 7 SUMs (4 in situ; mean thickness, 1.17mm; range, 0-4mm) and 4 SUSCCs (mean thickness, 3.4mm; range, 1.6 6mm). WLE of the nail unit was performed in 9 patients and amputation in 2 patients with invasive SUM. Mean follow-up was 39 months (range, 12-96 months) and no local or regional recurrences were detected. One of the 2 patients who underwent amputation developed metastasis to the brain and died. In our review of the literature, we identified 5 series of patients with SUSCC treated with WLE of the nail unit (105 patients) and 14 series of patients with SUM (243 patients). Based on an analysis of these cases and ours, it would appear that WLE of the nail unit is associated with a very low rate of local recurrence (<7%) and offers better functional and cosmetic outcomes than amputation. CONCLUSIONS: WLE of the nail unit is the treatment of choice for SUSCC without bone involvement and for thin noninvasive SUM (Breslow depth <1mm). It is also feasible in intermediate thickness SUMs when detailed histologic examination of the margins confirms complete resection. Amputation, by contrast, is the treatment of choice for SUSCCs with bone involvement, very thick SUMs (>4mm), and recurrent tumors. PMID- 30293554 TI - Systemic Treatment of Moderate to Severe Psoriasis in Pediatric Patients in Galicia, Spain: A Descriptive Study. AB - BACKGROUND AND OBJECTIVE: Studies on the use of systemic therapy for psoriasis in pediatric patients are scarce. The main aim of this study was to describe the systemic treatments used for moderate to severe psoriasis in pediatric clinical settings. The second aim was to describe the effectiveness and safety of these treatments. MATERIAL AND METHODS: Descriptive, cross-sectional, multicenter study of patients under 18 years of age with moderate to severe psoriasis who were being treated or had been treated with a systemic drug (conventional or biologic) or phototherapy. We recorded demographic and clinical information, treatments received, tolerance, adverse effects, and response to treatment. RESULTS: Data were collected for 40 patients (60% female; mean age, 13 years) who had received 63 treatments in total. The most common first treatment (n=40) was phototherapy (administered to 68% of patients), followed by acitretin (15%). The most common treatments overall (n=63) were phototherapy (57%) and methotrexate (16%). At week 12 (evaluation of systemic treatment and phototherapy), 66% of the patients were classified as good responders and 22% as partial responders. The respective rates for week 24 (evaluation of systemic treatment only) were 36% and 32%. The treatments were well tolerated (97%) and adverse effects were reported in just 11% of cases. There were no treatment discontinuations because of adverse effects. CONCLUSIONS: Phototherapy, followed by methotrexate, was the most common treatment for moderate to severe psoriasis in this series of patients under 18 years. The treatments showed a favorable safety profile and were associated with a good response rate of 66% at week 12 (systemic treatment and phototherapy) and 36% at week 24 (systemic treatment only). PMID- 30293555 TI - Clopidogrel Partially Counteracts Adenosine-5'-Diphosphate Effects on Blood Pressure and Renal Hemodynamics and Excretion in Rats. AB - BACKGROUND: Adenosine-5'-diphosphate (ADP) can influence intrarenal vascular tone and tubular transport, partly through activation of purine P2Y12 receptors (P2Y12 R), but their actual in vivo role in regulation of renal circulation and excretion remains unclear. METHODS: The effects of intravenous ADP infusions of 2 8mg/kg/hour were examined in anesthetized Wistar rats that were untreated or chronically pretreated with clopidogrel, 20mg/kg/24hours, a selective P2Y12-R antagonist. Renal blood flow (transonic probe) and perfusion of the superficial cortex and medulla (laser-Doppler fluxes) were measured, together with urine osmolality (Uosm), diuresis (V), total solute (UosmV), sodium (UNaV) and potassium (UKV) excretion. RESULTS: ADP induced a gradual, dose-dependent 15% decrease of mean arterial pressure, a sustained increase of renal blood flow and a 25% decrease in renal vascular resistance. Clopidogrel pretreatment attenuated the mean arterial pressure decrease, and did not significantly alter renal blood flow or renal vascular resistance. Renal medullary perfusion was not affected by ADP whereas Uosm decreased from 1,080 +/- 125 to 685 +/- 75 mosmol/kg H20. There were also substantial significant decreases in UosmV, UNaV and UKV; all these changes were attenuated or abolished by clopidogrel pretreatment. Two-weeks' clopidogrel treatment decreased V while UosmUosmV and UNaV increased, most distinctly after 7 days. Acute clopidogrel infusion modestly decreased mean arterial pressure and significantly increased outer- and decreased inner medullary perfusion. CONCLUSIONS: Our functional studies show that ADP can cause systemic and renal vasodilation and a decrease in mean arterial pressure, an action at least partly mediated by P2Y12 receptors. We confirmed that these receptors exert tonic action to reduce tubular water reabsorption and urine concentration. PMID- 30293556 TI - Recommendations of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU) on the utility of the determination of faecal calprotectin in inflammatory bowel disease. AB - The management of inflammatory bowel disease (IBD) is currently based on the objective evaluation of intestinal lesions. It would therefore be interesting to have access to simple and non-invasive tools to monitor IBD activity and to identify the presence of lesions. Faecal calprotectin (FC) is the main cytosolic protein of neutrophils, it is resistant to bacterial degradation and it is stable at room temperature for several days, characteristics that make it suitable for use in clinical practice. It can be used to differentiate between inflammatory and functional processes, it correlates with endoscopic activity, it is associated with clinical and endoscopic response to treatment and it has short term prognostic value. This paper offers an up-to-date perspective on the information that FC can provide clinicians to aid diagnosis, monitoring and management of IBD. PMID- 30293557 TI - Hypertension guidelines: How do they apply to kidney transplant recipients. AB - Hypertension is common among kidney transplant recipients and may result from traditional risk factors or transplant specific variables, which commonly include donor associated causes, immunosuppression, or transplant renal artery stenosis. Uncontrolled blood pressure in this patient population is associated with increased cardiovascular mortality and morbidity, and decreased graft survival. Despite these negative associations, there are no randomized controlled trials looking at the optimal blood pressure targets and identifying the best antihypertensive regimen for this special patient population. Multiple hypertension guidelines have been published in the last 10 years, but the Kidney Disease: Improving Global Outcomes (KDIGO) and American Society of Transplantation (AST) guidelines are the only to recommended a target blood pressure in kidney transplant recipients. In this manuscript, we will review the available evidence based on randomized clinical trials and large observational studies in kidney transplant recipients. Pending new interventional trials, we believe that: a) a blood pressure target of <=130/80 is a reasonable goal as suggested by KDIGO; b) the choice of antihypertensive agent should be based on the patients' other comorbidities; and c) achieving good blood pressure control is more important than the choice of the antihypertensive agent; however, the initial choice of antihypertensive medications should be calcium channel blockers, beta-blockers, diuretics, and angiotensin converting enzyme inhibitors/angiotensin receptor blockers as they have all been shown to reduce cardiovascular events in the general population. PMID- 30293558 TI - Overall and Cause-Specific Mortality of Inflammatory Bowel Disease in Olmsted County, Minnesota, From 1970 Through 2016. AB - OBJECTIVE: To determine the mortality of Crohn disease (CD) and ulcerative colitis (UC) and temporal trends in mortality. PATIENTS AND METHODS: All 895 residents of Olmsted County, Minnesota, first diagnosed as having inflammatory bowel disease (IBD) (411 with CD and 484 with UC) from January 1, 1970, through December 31, 2010, were followed through June 30, 2016. Standardized mortality ratios (SMRs) were computed-expected rates were derived from the US 2010 background population. To determine overall and cause-specific mortality, each patient with IBD was matched with 5 county residents, and Cox regression analysis was used to assess time to death. RESULTS: A total of 895 patients with IBD and 4475 patients without IBD were included. Seventy-four patients with CD died compared with 59.2 expected (SMR, 1.25; 95% CI, 0.98-1.57), and 77 patients with UC died compared with 108.1 expected (SMR, 0.71; 95% CI, 0.56-0.89). In CD, the risk of dying was significantly associated with diagnosis from 1970 through 1979 (SMR, 1.90; 95% CI, 1.24-2.78). Of those diagnosed after 1980, the risk of dying in patients with CD was similar to the US background population. In UC, the risk of dying was less than expected in all periods of diagnosis. In the Cox regression analysis, overall mortality was not significantly higher in CD (hazard ratio [HR], 1.26; 95% CI, 0.97-1.63) or UC (HR, 0.89; 95% CI, 0.70-1.14) compared with the comparison cohort. The risk of dying of digestive diseases (HR, 3.70; 95% CI, 1.24-11.0) and respiratory diseases (HR, 2.72; 95% CI, 1.36-5.44) was increased in CD but not UC. CONCLUSION: In this cohort, overall mortality in patients with CD diagnosed after 1980 did not differ from that in the US background population. Overall mortality in patients with UC diagnosed from 1970 through 2010 was lower than the expected mortality. PMID- 30293561 TI - Correction. PMID- 30293559 TI - Clockwork allergy: How the circadian clock underpins allergic reactions. AB - Allergic disease is characterized by marked day-night changes in the clinical symptoms and laboratory parameters of allergy. Recent reports suggest that the circadian clock, which drives a biological rhythm with a periodicity of approximately 24 hours in behavior and physiology, underpins a time of day dependent variation in allergic reactions. New studies also suggest that disruption of clock activity not only influences temporal variation but can also enhance the severity of allergic reactions and even increase susceptibility to allergic disease. These findings suggest that the circadian clock is a potent regulator of allergic reactions that plays more than a simple circadian timekeeping role in allergy. A better understanding of these processes will provide new insight into previously unknown aspects of the biology of allergies and can lead to the application of clock modifiers to treat allergic disease. Finally, this area of research provides a novel opportunity to consider how modern lifestyles in the developed world are changing the clinical manifestations of allergy as our society quickly transforms into a circadian rhythm-disrupted society in which sleeping, working, and eating habits are out of sync with endogenous circadian rhythmicity. Such findings might reveal lifestyle interventions that enable us to better control allergic disease. PMID- 30293562 TI - Is multiple-site colonization with Candida spp. related to inadequate response to individualized fluconazole maintenance therapy in women with recurrent Candida vulvovaginitis? AB - OBJECTIVE: Although most women on fluconazole maintenance therapy for recurrent vulvovaginal candidosis experience a substantial improvement in quality of life, some do not respond to therapy. Is candidal colonization of extragenital sites related to suboptimal response to maintenance therapy? PATIENTS AND METHODS: Women included in a multicenter follow-up study (ReCiDiF) were evaluated for clinical signs and presence of yeasts in nose, mouth, anus, perineum, and urine. Candida was diagnosed by positive microscopy, confirmed by positive culture or polymerase chain reaction. After treatment, women were divided into groups according to their response to a fluconazole maintenance regimen (optimal, suboptimal, and nonresponders). RESULTS: The most frequent extravaginal Candida spp. were detected in urine (79.5%), perineum (78.6%), and anus (56.4%). Carriers of Candida in the mouth were more likely to have it in the anus (OR 3.2; 95% CI 1.4-7.7). Colonization in anus (OR 3.3; 95% CI 1.3-8.1) or in multiple extravaginal sites (OR 3.0; CI95% 1.2-7.4) was related to nonresponse to therapy. Candidal carriage in the anus did not increase anal and perianal symptoms. CONCLUSION: Women with anal carriage and multiple-site candidal colonization are less likely to respond to individualized decreasing dose fluconazole therapy.

AB - Cardiac involvement can occur following bacteremia secondary to Neisseria meningitidis (Garcia et al. Rev Soc Bras Med Trop. 1999;32(5):517-5122) and is likely underrecognized. However, meningococcal disease presenting as primary myopericarditis in immunocompetent adults is a relatively rare phenomenon. We discuss an unusual presentation of meningococcal disease and the investigation and treatment strategies implemented. PMID- 30293565 TI - ANKRD9 is associated with tumor suppression as a substrate receptor subunit of ubiquitin ligase. AB - BACKGROUND: Human ANKRD9 (ankyrin repeat domain 9) expression is altered in some cancers. METHODS: We tested genetic association of ANKRD9 with gastric cancer susceptibility and examined functional association of ANKRD9 with altered proliferation of MKN45 gastric cancer cells. We then identified ANKRD9-binding partners in HEK 293 embryonic kidney cells using quantitative proteomics, western blotting and complex reconstitution assays. We finally demonstrated ANKRD9's role of recognizing substrates for ubiquitination using in vitro ubiquitylation assay. RESULTS: ANKRD9 is associated with cancer susceptibility in a comparison of single-nucleotide polymorphisms between 1092 gastric cancer patients and 1206 healthy controls. ANKRD9 depletion accelerates tumor progression by increasing cellular proliferation, piling up, and anchorage-independent growth of MKN45 cells. We discovered that ANKRD9 is a ubiquitin ligase substrate receptor subunit and has an anti-proliferative activity. ANKRD9 associates with CUL5 (not CUL2), ELOB, ELOC, and presumably RNF7 subunits, which together assemble into a cullin RING superfamily E3 ligase complex. ANKRD9 belongs to the ASB family of proteins, which are characterized by the presence of ankyrin repeats and a SOCS box. In addition to its interactions with the other E3 ligase subunits, ANKRD9 interacts with two isoforms of inosine monophosphate dehydrogenase (IMPDH). These IMPDH isoforms are cognate substrates of the ANKRD9-containing E3 enzyme, which ubiquitinates them for proteasomal degradation. Their ubiquitination and turnover require the presence of ANKRD9. CONCLUSION: ANKRD9, a previously unidentified E3 substrate receptor subunit, functions in tumor suppression by recognizing the oncoprotein IMPDH isoforms for E3 ubiquitination and proteasomal degradation.

AB - Loss-of-function mutations in the SIL1 gene are linked to Marinesco-Sjogren syndrome (MSS), a rare multisystem disease of infancy characterized by cerebellar and skeletal muscle degeneration. SIL1 is a ubiquitous adenine nucleotide exchange factor for the endoplasmic reticulum (ER) chaperone BiP. The complexity of mechanisms by which loss of SIL1 causes MSS is not yet fully understood. We used HeLa cells to test the hypothesis that impaired protein folding in the ER due to loss of SIL1 could affect secretory trafficking, impairing the transport of cargoes essential for the function of MSS vulnerable cells. Immunofluorescence and ultrastructural analysis of SIL1-knocked-down cells detected ER chaperone aggregation, enlargement of the Golgi complex, increased autophagic vacuoles, and mitochondrial swelling. SIL1-interefered cells also had delayed ER-to-plasma membrane transport with retention of Na+/K+-ATPase and procollagen-I in the ER and Golgi, and increased apoptosis. The PERK pathway of the unfolded protein response was activated in SIL1-interfered cells, and the PERK inhibitor GSK2606414 attenuated the morphological and functional alterations of the secretory pathway, and significantly reduced cell death. These results indicate that loss of SIL1 is associated with alterations of secretory transport, and suggest that inhibiting PERK signalling may alleviate the cellular pathology of SIL1-related MSS. PMID- 30293567 TI - BRG1 regulates NOX gene transcription in endothelial cells and contributes to cardiac ischemia-reperfusion injury. AB - Excessive accumulation of reactive oxygen species (ROS) is considered a major culprit for a host of cardiovascular diseases. In vascular endothelial cells, ROS production is mediated by NAPDH oxidases (NOX). In the present study we investigated the role of the chromatin remodeling protein BRG1 in NOX trans activation as well as its implication in cardiac ischemia-reperfusion injury. We report that in response to hypoxia-reoxygenation (HR) BRG1 was recruited to the NOX promoter regions in both immortalized endothelial cells and primary microvascular endothelial cells. BRG1 knockdown attenuated the induction of NOX genes by HR stimulation. Suppression of NOX trans-activation by BRG1 silencing was paralleled by the loss of active histone modifications (acetylation of histones H3 and H4) and the re-appearance of repressive histone modification (dimethylation of histone H3K9) surrounding the NOX promoter. Of interest, the H3K9 demethylase KDM3A bound to the NOX promoters with kinetics similar to BRG1 and interacted with BRG1 to activate NOX transcription. KDM3A depletion ameliorated NOX induction and ROS production in endothelial cells exposed to HR. Finally, mice with endothelial-specific deletion of BRG1 were protected from cardiac ischemia-reperfusion injury. In conclusion, our data suggest that BRG1 may link epigenetic activation of NOX transcription in endothelial cells to cardiac ischemia reperfusion injury. PMID- 30293568 TI - The chromatin remodeling protein BRG1 regulates APAP-induced liver injury by modulating CYP3A11 transcription in hepatocyte. AB - Acetaminophen (APAP) overdose represents the most frequent cause of acute liver failure. The underlying epigenetic mechanism is not fully understood. In the present study we investigated the mechanism whereby the chromatin remodeling protein brahma related gene 1 (Brg1) regulates APAP induced liver injury in mice. We report that hepatocyte-specific deletion of Brg1 attenuated APAP induced liver injury in mice as evidenced by reduced plasma ALT and AST levels, decreased liver necrosis, amelioration of GSH depletion, and prolonged survival. Brg1 regulated APAP-induced liver injury likely by stimulating the transcription of Cyp3a11, a key cytochrome enzyme involved in APAP metabolism. Immunoprecipitation coupled with DNA affinity microarray identified hepatocyte nuclear factor 4 (HNF4) as a novel binding partner for Brg1. HNF4 recruited Brg1 to the Cyp3a11 promoter and formed a complex with Brg1 to trans-activate Cyp3a11. In contrast, BRG1 deficiency attenuated HNF4 binding to the Cyp3a11 promoter and dampened Cyp3a11 transcription. Therefore, our data suggest that Brg1 might play an essential role mediating APAP induced liver injury in vivo. PMID- 30293569 TI - Deciphering OPA1 mutations pathogenicity by combined analysis of human, mouse and yeast cell models. AB - OPA1 is the major gene responsible for Dominant Optic Atrophy (DOA) and the syndromic form DOA "plus". Over 370 OPA1 mutations have been identified so far, although their pathogenicity is not always clear. We have analyzed one novel and a set of known OPA1 mutations to investigate their impact on protein functions in primary skin fibroblasts and in two "ad hoc" generated cell systems: the MGM1/OPA1 chimera yeast model and the Opa1-/- MEFs model expressing the mutated human OPA1 isoform 1. The yeast model allowed us to confirm the deleterious effects of these mutations and to gain information on their dominance/recessivity. The MEFs model enhanced the phenotypic alteration caused by mutations, nicely correlating with the clinical severity observed in patients, and suggested that the DOA "plus" phenotype could be induced by the combinatorial effect of mitochondrial network fragmentation with variable degrees of mtDNA depletion. Overall, the two models proved to be valuable tools to functionally assess and define the deleterious mechanism and the pathogenicity of novel OPA1 mutations, and useful to testing new therapeutic interventions. PMID- 30293570 TI - Combined effects of aquaporin-4 and hypoxia produce age-related hydrocephalus. AB - Aquaporin-4, present in ependymal cells, in glia limiting and abundantly in pericapillary astrocyte foot processes, and aquaporin-1, expressed in choroid plexus epithelial cells, play an important role in cerebrospinal fluid production and may be involved in the pathophysiology of age-dependent hydrocephalus. The finding that brain aquaporins expression is regulated by low oxygen tension led us to investigate how hypoxia and elevated levels of cerebral aquaporins may result in an increase in cerebrospinal fluid production that could be associated with a hydrocephalic condition. Here we have explored, in young and aged mice exposed to hypoxia, whether aquaporin-4 and aquaporin-1 participate in the development of age-related hydrocephalus. Choroid plexus, striatum, cortex and ependymal tissue were analyzed separately both for mRNA and protein levels of aquaporins. Furthermore, parameters such as total ventricular volume, intraventricular pressure, cerebrospinal fluid outflow rate, ventricular compliance and cognitive function were studied in wild type, aquaporin-1 and aquaporin-4 knock-out animals subjected to hypoxia or normoxia. Our data demonstrate that hypoxia is involved in the development of age-related hydrocephalus by a process that depends on aquaporin-4 channels as a main route for cerebrospinal fluid movement. Significant increases in aquaporin-4 expression that occur over the course of animal aging, together with a reduced cerebrospinal fluid outflow rate and ventricular compliance, contribute to produce more severe hydrocephalus related to hypoxic events in aged mice, with a notable impairment in cognitive function. These results indicate that physiological events and/or pathological conditions presenting with cerebral hypoxia/ischemia contribute to the development of chronic adult hydrocephalus. PMID- 30293572 TI - Adiponectin inhibits hepatic stellate cell activation by targeting the PTEN/AKT pathway. AB - Adiponectin inhibits hepatic stellate cell (HSC) activation and subsequent development of liver fibrosis via multiple mechanisms. Phosphatase and tensin homolog deletion 10 (PTEN) plays a crucial role in suppression of HSC activation, but its regulation by adiponectin is not fully understood. Here, we investigated the effect of adiponectin on PTEN in LX-2 cells, a human cell line and examined the underlying molecular mechanisms involved in adiponectin-mediated upregulation of PTEN activity during fibrosis. PTEN expression was found to be significantly reduced in the livers of mice treated with CCl4, whereas its expression was rescued by adiponectin treatment. The DNA methylation proteins DNMT1, DNMT3A, and DNMT3B are all highly expressed in activated primary HSCs compared to quiescent HSCs, and thus represent additional regulatory targets during liver fibrogenesis. Expression of DNMT proteins was significantly induced in the presence of fibrotic stimuli; however, only DNMT3B expression was reduced in the presence of adiponectin. Adiponectin-induced suppression of DNMT3B was found to be mediated by enhanced miR-29b expression. Furthermore, PTEN expression was significantly increased by overexpression of miR-29b, whereas its expression was markedly reduced by a miR-29b inhibitor in LX-2 cells. These findings suggest that adiponectin-induced upregulation of miR-29b can suppress DNMT3B transcription in LX-2 cells, thus resulting in reduced methylation of PTEN CpG islands and ultimately suppressing the PI3K/AKT pathway. Together, these data suggest a possible new explanation for the inhibitory effect of adiponectin on HSC activation and liver fibrogenesis. PMID- 30293571 TI - Mechanisms underlying modulation of podocyte TRPC6 channels by suPAR: Role of NADPH oxidases and Src family tyrosine kinases. AB - The soluble urokinase receptor (suPAR) has been implicated in the pathogenesis of chronic kidney diseases (CKD) and may function as a circulating "permeability factor" driving primary focal and segmental glomerulosclerosis (FSGS). Here we examined the mechanisms whereby suPAR causes mobilization and increased activation of Ca2+-permeable TRPC6 channels, which are also implicated in FSGS. Treatment of immortalized mouse podocytes with recombinant suPAR for 24 h caused a marked increase in cytosolic reactive oxygen species (ROS) that required signaling through integrins. This effect was associated with increased assembly of active cell surface NADPH oxidase 2 (Nox2) complexes and was blocked by the Nox2 inhibitor apoycynin. Treatment with suPAR also evoked a functionally measurable increase in TRPC6 channels that was blocked by concurrent treatment with the ROS-quencher TEMPOL as well as by inhibition of Rac1, an essential component of active Nox2 complexes. Elevated ROS evoked by exposing cells to suPAR or H2O2 caused a marked increase in the abundance of tyrosine phosphorylated proteins including Src, and suPAR-evoked Src activation was blocked by TEMPOL. Moreover, mobilization and increased activation of TRPC6 by suPAR or H2O2 was blocked by concurrent exposure to PP2, an inhibitor of Src family tyrosine kinases. These data suggest that suPAR induces oxidative stress in podocytes that in turn drives signaling through Src family kinases to upregulate TRPC6 channels. The combination of oxidative stress and altered Ca2+ signaling may contribute to loss of podocytes and progression of various forms of CKD. PMID- 30293573 TI - Chemical chaperone 4-phenylbutyric acid alleviates the aggregation of human familial pulmonary fibrosis-related mutant SP-A2 protein in part through effects on GRP78. AB - G231V and F198S mutations in surfactant protein A2 (SP-A2) are associated with familial pulmonary fibrosis. These mutations cause defects in dimer/trimer assembly, trafficking, and secretion, as well as cause mutant protein aggregation. We investigated the effects and mechanisms of chemical chaperones on the cellular and biochemical properties of mutant SP-A2. Chemical chaperones, including 4-phenyl butyric acid (4-PBA), could enhance secretion and decrease intracellular aggregation of mutant SP-A2 in a dose-dependent manner. Interestingly, increased levels of aggregated mutant SP-A2, resulting from MG-132 mediated proteasome inhibition, could also be alleviated by 4-PBA. 4-PBA treatment reduced the degradation of mutant SP-A2 to chymotrypsin digestion in CHO-K1 cells and up-regulated GRP78 (BiP) expression. Overexpression of GRP78 in SP-A2 G231V- or F198S-expressing cells reduced, whereas shRNA-mediated knockdown of GRP78 enhanced aggregation of mutant SP-A2, suggesting that GRP78 regulates aggregation of mutant SP-A2. Together, these data indicate chemical chaperone 4 PBA and upregulation of GRP78 can alleviate aggregation to stabilize and facilitate secretion of mutant SP-A2. The up-regulation expression of GRP78 might partially contribute to the aggregate-alleviating effect of 4-PBA. PMID- 30293574 TI - N-methyl-D-aspartate receptor-mediated calcium influx connects amyloid-beta oligomers to ectopic neuronal cell cycle reentry in Alzheimer's disease. AB - INTRODUCTION: Alzheimer's disease (AD) symptoms reflect synaptic dysfunction and neuron death. Amyloid-beta oligomers (AbetaOs) induce excess calcium entry into neurons via N-methyl-D-aspartate receptors (NMDARs), contributing to synaptic dysfunction. The study described here tested the hypothesis that AbetaO stimulated calcium entry also drives neuronal cell cycle reentry (CCR), a prelude to neuron death in AD. METHODS: Pharmacologic modulators of calcium entry and gene expression knockdown were used in cultured neurons and AD model mice. RESULTS: In cultured neurons, AbetaO-stimulated CCR was blocked by NMDAR antagonists, total calcium chelation with 1,2-Bis(2-aminophenoxy)ethane-N,N,N',N' tetraacetic acid tetrakis(acetoxymethyl ester) (BAPTA-AM), or knockdown of the NMDAR subunit, NR1. NMDAR antagonists also blocked the activation of calcium calmodulin-dependent protein kinase II and treatment of Tg2576 AD model mice with the NMDAR antagonist, memantine, prevented CCR. DISCUSSION: This study demonstrates a role for AbetaO-stimulated calcium influx via NMDAR and CCR in AD and suggests the use of memantine as a disease-modifying therapy for presymptomatic AD. PMID- 30293575 TI - Consent recommendations for research and international data sharing involving persons with dementia. AB - Consent is generally required for research and sharing rich individual-level data but presents additional ethical and legal challenges where participants have diminished decision-making capacity. We formed a multi-disciplinary team to develop best practices for consent in data-intensive dementia research. We recommend that consent processes for research and data sharing support decision making by persons with dementia, protect them from exploitation, and promote the common good. Broad consent designed to endure beyond a loss of capacity and combined with ongoing oversight can best achieve these goals. Persons with dementia should be supported to make decisions and enabled to express their will and preferences about participation in advance of a loss of capacity. Regulatory frameworks should clarify who can act as a representative for research decisions. By promoting harmonization of consent practices across institutions, sectors, and countries, we hope to facilitate data sharing to accelerate progress in dementia research, care, and prevention. PMID- 30293576 TI - Human metabolomics reveal daily variations under nutritional challenges specific to serum and skeletal muscle. AB - OBJECTIVE: Advances in the field of metabolomics and the concomitant development of bioinformatics tools constitute a promising avenue towards the development of precision medicine and personalized profiling for numerous disease states. Studies in animal models have strengthened this concept, but the application in human subjects is scarce. METHODS: Utilizing high-throughput metabolomics, we have analyzed the metabolome levels of human serum and skeletal muscle in the morning and evening in response to divergent nutritional challenges in order to identify unique signatures present in serum and muscle. RESULTS: We reveal dynamic daily variation of human metabolome unique to serum and muscle. The overall effect of nutritional challenges on the serum and muscle metabolome results in a profound rewiring of morning-evening metabolic profiles in human participants in response to the timing and type of dietary challenge. CONCLUSION: We highlight time-of-day and meal-composition dependence of reprogramming of human metabolome by nutritional challenges. PMID- 30293579 TI - Implications of the local hemodynamic forces on the formation and destabilization of neoatherosclerotic lesions. AB - OBJECTIVE: To examine the implications of endothelial shear stress (ESS) distribution in the formation of neoatherosclerotic lesions. METHODS: Thirty six patients with neoatherosclerotic lesions on optical coherence tomography (OCT) were included in this study. The OCT data were used to reconstruct coronary anatomy. Blood flow simulation was performed in the models reconstructed from the stent borders which it was assumed that represented the lumen surface at baseline, immediate after stent implantation, and the estimated ESS was associated with the neointima burden, neoatherosclerotic burden and neointima characteristics. In segments with neointima rupture blood flow simulation was also performed in the model representing the lumen surface before rupture and the ESS was estimated at the ruptured site. RESULTS: An inverse association was noted between baseline ESS and the incidence and the burden of neoatherosclerotic (beta = -0.60, P < 0.001, and beta = -4.05, P < 0.001, respectively) and lipid-rich neoatherosclerotic tissue (beta = -0.54, P < 0.001, and beta = -3.60, P < 0.001, respectively). Segments exposed to low ESS (<1 Pa) were more likely to exhibit macrophages accumulation (28.2% vs 10.9%, P < 0.001), thrombus (11.0% vs 2.6%, P < 0.001) and evidence of neointima discontinuities (8.1% vs 0.9%, P < 0.001) compared to those exposed to normal or high ESS. In segments with neointima rupture the ESS was high at the rupture site compared to the average ESS over the culprit lesion (4.00 +/- 3.65 Pa vs 3.14 +/- 2.90 Pa, P < 0.001). CONCLUSIONS: Local EES is associated with neoatherosclerotic lesion characteristics, which suggests involvement of ESS in the formation of vulnerable plaques in stented segments. PMID- 30293577 TI - Maternal exercise intervention in obese pregnancy improves the cardiovascular health of the adult male offspring. AB - OBJECTIVE: Obesity during pregnancy is associated with an elevated risk of cardiovascular disease in the offspring. With increased numbers of women entering pregnancy overweight or obese, there is a requirement for targeted interventions to reduce disease risk in future generations. Using an established murine model of maternal obesity during pregnancy, we investigated if a treadmill exercise intervention in the mother could improve offspring cardiac health and explored potential underlying mechanisms. METHODS: A 20-minute treadmill exercise intervention protocol was performed 5 days a week in diet-induced obese female C57BL/6 mice 1 week prior to, and up to E17 of pregnancy. All male offspring were weaned onto a control diet and studied at 8 weeks of age when their cardiovascular physiology was assessed by in vivo echocardiography and non invasive tail cuff plethysmography. Cardiomyocyte cell area, re-expression of fetal genes and the expression of calcium handling and sympathetic activation proteins were determined. RESULTS: At 8 weeks, there was no difference in bodyweight or fat mass between groups. Offspring of obese dams developed pathologic cardiac hypertrophy, hypertension and cardiac dysfunction characterized by reduced ejection fraction (p < 0.001). Maternal exercise prevented cardiac hypertrophy and dysfunction but failed to prevent hypertension. These offspring of exercised dams also had enhanced (p < 0.001) levels of calcium handling proteins and a sympathetic-activated inotropic response. CONCLUSIONS: Exercise in obese pregnancy was beneficial to offspring cardiac function and structure but did not influence hypertension suggesting they are programmed by separate mechanistic pathways. These data suggest combination interventions in obese pregnancies will be required to improve all aspects of the cardiovascular health of the next generation.

AB - INTRODUCTION: Ocular tuberculosis (OTB) is a rare form of tuberculosis. Diagnosis is usually presumptive based on epidemiology, clinical findings and positivity of immune response. The aim of the study was to characterize the OTB cases identified in Lisbon. METHODS: Retrospective study on OTB cases diagnosed in Lisbon from 2012 to 2015. The authors gathered data regarding demographic characteristics, diagnostic criteria, type of treatment as well as therapeutic results. RESULTS: There were 39 reported cases of presumed OTB which accounted for 12.2% of all reported TB cases. Patients had a mean age of 55.5 years. All had ocular manifestations (mainly uveitis). Diagnostic criteria included positive tuberculin skin test (TST) and/or Interferon Gamma Release Assay (IGRA). Culture testing or PCR could not be determined in any patient. Patients had OTB treatment for an average of 9.08 months. Clinical improvement was reported in 91.4% of treated patients. There were no relapses. CONCLUSION: This is the first published series about OTB in Lisbon. All cases had a presumptive diagnosis made through TST and/or IGRA testing. Most of treated patients improved, with no signs of relapse and a median 29.9-month follow up. OTB seems to be a growing diagnosis and treatment may be beneficial even in patients with a presumptive diagnosis. PMID- 30293583 TI - Editorial for BBRC lipidomics special issue.

AB - The distribution of wealth within and between countries is unequal, a reality that has preoccupied economists since their discipline's origins. Poverty and income inequality are intimately tied to health outcomes, including for pediatric neurologic disease. This article provides an overview of the distribution of the global poor and global poverty reduction efforts. The emergence of a global middle class is discussed, as are issues related to income inequality within wealthy nations. PMID- 30293585 TI - Global Burden of Pediatric Neurological Disorders. AB - Neurological conditions in children represent a significant proportion of the global burden of disease, since they contribute to premature mortality and years lived with disability. The burden of neurological conditions, as measured by the total disability adjusted live years has decreased significantly over the last 25 years (1990-2015), mainly due to the reduction in the mortality, as the years lived with disability has increased slightly. However, in some regions of the world, notably South Asia and sub-Saharan Africa, the burden remains high, driven by the high incidence of prematurity, neonatal encephalopathy and infections of the central nervous system. PMID- 30293586 TI - Socioeconomic Status and Pediatric Neurologic Disorders: Current Evidence. AB - Socioeconomic status (SES) is an important risk factor for many neurological disorders and a determinant of health outcomes and quality of life, especially for individuals with neurologic disorders and developmental disabilities. This article focuses on the relationship between SES and pediatric epilepsy, cerebral palsy, autism spectrum disorder, and intellectual disability. Disparities in the prevalence and long-term impact of SES on functioning in persons with disabilities are observed worldwide. Clinicians can use the information presented in the article to target early identification and interventions for improving outcomes in populations most at risk for these disorders and for poor health, social, and economic outcomes. PMID- 30293587 TI - Imaging Evidence of the Effect of Socio-Economic Status on Brain Structure and Development. AB - Numerous studies have shown an association between children's socio-economic status (SES) and disparities in neurocognitive development, achievements, and function later in life. Research focus has recently shifted to imaging of the brain's response to the child's environment. This review summarizes the emerging studies on the influences of early-life SES on brain structure and development, and addresses the relation between brain development and enriched environments. The studies provide evidence of significant associations between SES and brain structure, growth and maturation, not only in healthy infants and children but also in infants with medical conditions. This suggests that the relation between SES and later-life function and achievements operates through alterations in brain maturation. Although the brain changes seem to persist without intervention, animal models of environmental enrichment show the potential of SES related brain changes to be reversible and dynamic. This review underscores the critical need for reducing the impact of socio-economic disparities and early targeted and prolonged interventions, and highlights the potential of these interventions leading to optimal opportunities for our youngest. PMID- 30293588 TI - A Developmental Social Neuroscience Model for Understanding Pathways to Substance Use Disorders During Adolescence. AB - Adolescence is a transitional period of development characterized by critical changes in physical, neural, cognitive, affective, and social functions. Studies investigating the underlying mechanisms of substance use at levels of self report, brain response, and behavioral data are generally consistent with suggestions from dual-process model that differential growth rates of frontally mediated control and striato-frontal reward processing are related to a heightened risk of substance use during adolescence. However, social theories highlight the important role of social context and environment in which adolescents grow up and suggest that growing up in an unfavorable environment and in particular exposure to adverse childhood experiences play a huge role in how this vulnerability is translated into actual risk. In this review, we provide a summary of recent theories that examine a number of key individual and social and environmental risk factors underlying risk for early initiation and escalation of substance misuse. We also present a model that expands the dual-process model to incorporate the role of negative self-concept and negative affect associated with growing up in an unfavorable environment and their interactions with cognitive control and inhibition to further explain vulnerability to early initiation and development of substance misuse in adolescents. PMID- 30293589 TI - Justice and Neurodevelopmental Disability: Moral-Political Philosophies, Policies, and Their Outcomes. AB - Neurodevelopmental disabilities, such as cerebral palsy and autism, touch a population which has been dubbed to be "doubly vulnerable." Individuals with neurodevelopmental disability have conditions that impair their cognition, communication, mobility, or social interactions, and they also rely on others to make decisions on their behalf. Accordingly, these children-as described in other contributions of this special issue-are particularly prone to suffer from systemic (ie, social, economic, and political) conditions that give or prevent access to quality and timely health care and social services as well as economic opportunities. In this article, we expose 2 different views on the principle of justice (justice as equality and justice as fairness). We then examine policy approaches and general outcomes of 3 countries (Sweden, the United States of America, and the United Kingdom), which have opted for different policy orientations. The United Kingdom's targeted approach to neurodevelopmental disability seems to be generating interesting results while the more general Swedish approach is not without merits, although perhaps more difficult to apply to other countries. Given knowledge gaps, there is great need to compare different policy approaches to neurodevelopmental disability and their real-world implications on the life of individuals and their families. PMID- 30293590 TI - Promoting the Human Rights of Children With Neurologic Conditions. AB - Children with neurologic conditions benefit from international conventions, and national treaties, policies and regulations that safeguard their human rights. These regulations also exist to serve as guidance in the creation of comprehensive systems of care, inclusive environments, accessible societies and communities that allow these children to thrive and to achieve the best of their capacities. This narrative review of issues related to human rights and advocacy in pediatric neurologic disabilities will provide an overview of the human rights conventions that relate to children with disabilities, and the most current approaches implicating health care providers in rights promotion for these individuals and their families. We also suggest venues for professionals to advocate for their patients, and suggest strategies to consider rights-based approaches as a mean to provide holistic care in a social neurology framework. PMID- 30293591 TI - N-docosahexaenoylethanolamine detected in human breast milk. AB - PURPOSE: Measure concentrations of the neurogenic, pro-neurogenic, pro synaptogenic and anti-inflammatory mediator N-docosahexaenoylethanolamine (synaptamide) in relation to its precursor docosahexaenoic acid (DHA) in breast milk. DESIGN AND METHODS: Postpartum women were recruited prior to discharge. We supplemented half the subjects with omega-3 fatty acids. Breast milk samples were collected at 1, 4 and 8 weeks. Synaptamide and DHA concentrations were determined by liquidchromatography/tandem mass spectrometry (LC-MS/MS) and gas chromatography, respectively. RESULTS: Synaptamide was detected in all breast milk samples. The concentration ranged from 44 to 257 fmol/mL. Omega-3 fatty acid supplementation did not affect DHA or synaptamide concentration in breast milk due to a high-DHA-containing diet self-selected by control mothers. Nevertheless, synaptamide levels significantly correlated with DHA concentration in breast milk (r = 0.624, P < 0.001). CONCLUSION: This is the first demonstration of detectable concentrations of synaptamide in human breast milk. Although the attempt to raise the milk DHA content by omega-3 fatty acid supplementation was not successful in the current study, the positive correlation observed between synaptamide and DHA concentration suggests that synaptamide levels in human milk can be raised by proper omega-3 fatty acid supplementation that is known to increase DHA. PMID- 30293592 TI - A stable method for routine analysis of oxylipins from dried blood spots using ultra-high performance liquid chromatography-tandem mass spectrometry. AB - Oxylipins are biologically important lipid mediators that are derived enzymatically from polyunsaturated fatty acids (PUFA) and have a major role in regulating inflammatory processes. The currently available methods for measuring oxylipins from human biological samples have limitations, which restricts their use in large studies. We have developed a novel method for measuring 21 oxylipins from dried blood spot (DBS) using ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) and stable isotope dilution analysis. Our new method is reproducible and precise and enables the high throughput analysis and quantitation of bioactive oxylipins in small volumes of blood. In the future, this new method can be readily applied to measure oxylipins in large studies. Abstract Oxylipins are downstream lipid mediators enzymatically-produced from polyunsaturated fatty acids (PUFA) that are implicated as the biological effectors of these fatty acids. Recently reported methods for the quantitation of oxylipins require complex extraction procedures. In this study, we report the development and validation of a novel system for the quantitation of 21 individual oxylipins from a dried blood spot (DBS) using ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) and stable isotope dilution analysis. Linearity and precision of the method were determined and the stabilities of the 12 most abundant oxylipins were tested during 2 months of storage at room temperature, after being spiked into blood and prepared as DBS on PUFAcoatTM paper. Responses were linear across the concentration range analysed for all oxylipins (r2 values ranged from 0.953 to 0.998). Intra-day and inter-day variations were <=16% for all oxylipins. Recovery of oxylipins from the DBS ranged from 80 - 115%. The 12 spiked oxylipins were stable for 2 months when stored as DBS at room temperature. Our method is reproducible and precise, and provides the opportunity to accurately quantitate these oxylipins in a small sample volume. PMID- 30293593 TI - Moderating effect of PLIN4 genetic variant on impulsivity traits in 5-year-old children born small for gestational age. AB - Poor fetal growth is associated with long-term behavioral, metabolic and psychiatric alterations, including impulsivity, insulin resistance, and mood disorders. However, the consumption of omega-3 polyunsaturated fatty acid (n-3 PUFA) seems to be protective for this population, improving inhibitory control and behavioral reactivity. We investigated whether the presence of the A allele of rs8887 SNP (PLIN4 gene), known to be associated with increased sensitivity to the consumption of n-3 PUFAs, interacts with fetal growth influencing inhibitory control. 152 five-year-old children were genotyped and performed the Stop Signal Task (SSRT). There was a significant interaction between birth weight and the presence of the A allele on SSRT performance, in which lower birth weight associated with poorer inhibitory control only in non-carriers. These results suggest that a higher responsiveness to n-3 PUFAS protects small for gestational age children from developing poor response inhibition, highlighting that optimizing n-3 PUFA intake may benefit this population.

AB - Oxylipins are lipid mediators produced from polyunsaturated fatty acid (PUFA) metabolism, and are thought to be a molecular explanation for the diverse biological effects of PUFAs. Like PUFAs, oxylipins are distinguished by their omega-6 (n6) or omega-3 (n3) chemistry. We review the use of n6 oxylipins as biomarkers of disease and their use in diagnosis and risk assessment. We show cases where oxylipins derived from linoleate (LA) or arachidonate (AA) produced by the activities of lipoxygenase, cyclooxygenase, epoxygenase, omega/omega-1 hydroxylase, and autooxidation are useful as biomarkers or risk markers. HODEs, KODEs, EpOMEs, DiHOMEs, and other metabolites of LA as well as prostanoids, HETEs, KETEs, EpETrEs, and DiHETrEs, and other metabolites of AA were useful for understanding the different signaling environments in conditions from traumatic brain injury, to major coronary events, dyslipidemia, sepsis, and more. We next evaluate interventions that alter the concentrations of n6 oxylipins in plasma. We note the utility and response of each plasma fraction, and the generally increasing utility from the non-esterified, to the esterified, to the lipoprotein fractions. Finally, we review the effects which are specifically related to n6 oxylipins and most likely to be beneficial. Both n6 and n3 oxylipins work together in an exceedingly complex matrix to produce physiological effects. This overview should provide future investigators with important perspectives for the emerging utility of n6 oxylipins as products of n6 PUFAs in human health. PMID- 30293595 TI - Genetic variant in the 3'-untranslated region of the COX2 gene is associated with type 2 diabetes: A hospital-based case-control study. AB - Type 2 diabetes (T2DM) is caused by the decreased beta-cell mass and insulin deficiency, and disease is characterized by hypoglycemia. The insulin resistance also plays an important role in T2DM pathogenesis. Insulin resistance is the reduced biological response to insulin at the normal concentration in the circulation and develops with the influence of environmental factors with genetic abnormalities. In recent years, it has been reported that inflammatory pathway causes activation of the insulin resistance. Chronic inflammation inhibits the insulin sensitivity through activation of signaling pathways which are directly associated with the key components of insulin signaling pathway. Cyclooxygenase (COX) enzymes are key enzymes that catalysis prostaglandin synthesis from arachidonic acid. COX2 is an inducible COX isoform and that plays an important role in inflammatory process by leading the synthesis of pro- and anti- inflammatory prostaglandins. In our study, we aimed to investigate the relationship between variants of COX-2 gene which is one of the key components of the inflammatory pathway, and T2DM risks. In this study, we evaluated rs5275 and rs689466 variants located on the COX-2 gene by PCR-RFLP in 100 T2DM patients and 100 control subjects. The interaction among COX2 variants and T2DM was analyzed using appropriate methods. The both variants were in Hardy-Weinberg equilibrium in patients and controls (p > 0.05). A significant association was observed for genotype distribution of COX2 rs5275 site between control and T2DM cases (p = 0.042). In a dominant model, the cases who had at least one copy of allele C, were at increased risk of T2DM (p = 0.016). We found no significant association for the COX2 rs689466 domain by evaluating homozygous, heterozygous, dominant, and recessive models (p > 0.05). According to our data, the rs5275 variant of the COX2 in the 3'-UTR may contribute to the etiology or modulate the risk of T2DM, whereas the rs689466 variant of the COX2 gene is not associated with T2DM risk. PMID- 30293596 TI - A diet enriched in longer chain omega-3 fatty acids reduced placental inflammatory cytokines and improved fetal sustainability of C57BL/6 mice. AB - Omega (n)-3 polyunsaturated fatty acids (PUFA) are important regulators of inflammatory response that may impact pregnancy outcome. The effects of breeding chow diets containing n-3 PUFA from either fish oil (FO) or soybean oil (SO) were investigated on tissue fatty acid composition, inflammatory cytokines and pregnancy outcome. Female C57BL/6 mice (7 weeks old) were fed FO or SO diets for 2 weeks before mating and throughout pregnancy. Animals were sacrificed before and during pregnancy at day 6.5, 12.5 and 18.5. The FO diet increased the incorporation of n-3 PUFA in placenta, with a concomitant decrease in the concentration of pro-inflammatory cytokines. The FO diet increased the mRNA expression of placental specific PUFA transporter, which coincided with accretion of n-3 PUFA in fetal brain. Sites of fetal resorption were noticeable in the SO group but not in the FO group. N-3 PUFA may improve fetal sustainability via altering cytokine levels. PMID- 30293597 TI - Acute fish oil supplementation modulates the inflammatory response after strenuous exercise in obese men: A cross-over study. AB - AIM: To evaluate the effects of acute fish oil supplementation (FOS) in DNA damage, lymphocyte phenotype and cytokines production after strenuous exercise in obese individuals. METHODS: Sixteen sedentary obese (BMI >30.0 to <35.0 kg/m2) men performed two sessions of exhaustive exercise and consumed 2000 mg of either placebo or fish oil one hour before the exercise session; trials were separated by 14 days. Peripheral blood mononuclear cells were collected pre, immediately after and 1 h after both exercise sessions and stimulated in vitro with 2% phytohemagglutinin for cytokines secretion (IL-6, IL-8, TNF-alpha). Analysis of DNA damage index on total lymphocytes and the peripheral frequency of T helper CD4+ cells, T cytotoxic CD8+ cells, and CD19+ B cells were also performed. RESULTS: FOS prevented the increase in serum cortisol levels and the production of TNF-alpha and IL-8 after strenuous exercise. The DNA damage index decreased 1 h after exercise in FOS trial. Moreover, a lymphocytosis, i.e. increases in the frequency of CD4+ and CD8+ T cells was observed immediately after exercise bout in both trials. Moreover, FOS prevented the decrease in CD8+ T cells below to baseline value 1 h after strenuous exercise. CONCLUSION: Acute supplementation with fish oil attenuates the proinflammatory cytokine response and diminished the DNA damage after strenuous exercise in obese individuals, suggesting a possible protective effect against the exacerbation of systemic damage induced by exhaustive exercise in obese individuals.

AB - Existing advanced traffic management and emerging connected vehicles (CVs) technology can generate considerable amount of data on vehicle positions and trajectories. This data can be used for real-time safety optimization of intersections. To achieve this, it is essential to first understand how changes in signal control affect safety in real-time. This paper develops conflict-based safety performance functions (SPFs) of signalized intersections at the cycle level using multiple traffic conflict indicators. The developed SPFs relate various dynamic traffic parameters to the number of rear-end conflicts at the signal cycle. The traffic parameters included: queue length, shock wave speed and area, and the platoon ratio. The Time-to-Collision, the Modified-Time-to Collision, and the Deceleration Rate to Avoid the Crash were used as traffic conflict indicators. Traffic video-data collected from six signalized intersections was used in the analysis. The SPFs were developed using the Full Bayesian approach to address the unobserved heterogeneity and the variation among different sites. Overall, the results showed that all the developed SPFs have good fit with all explanatory variables being statistically significant. Also, the highest conflict frequency was noticed at the beginning of the green time, while the highest conflict severity was noticed at the beginning of the red time. Lastly, the results can be used most beneficially in real-time safety optimization of signalized intersection. PMID- 30293599 TI - Ten Steps to Improve Cardiac Arrest Survival in Your Community. AB - Creating a system of care for out of hospital cardiac arrest (OHCA) is not a simple task. It must be a multifaceted approach that encompasses a variety of teams from call takers, to bystanders, to emergency medical service (EMS) personnel, to hospital personnel. All of these teams must line up and perform their individual task successfully to yield a survivor of OHCA and return a loved one to his or her family. Various best practices have been collected and are highlighted here. Implementation of these concepts in one's system of care for OHCA will not be easy but will result in a greater number of survivors returning to their family in the community. PMID- 30293600 TI - The Critical Role of Dispatch. AB - There are 240 million 9-1-1 calls in the United States every year. The burden of managing these emergencies until first responders can arrive is on the dispatchers working in the 5806 public safety answering points, more commonly known as dispatch centers. They are the first link in the chain of survival between the public and the remainder of the health care system. Dispatchers play a critical role in the early identification of emergencies, assignment of appropriate emergency resources, and provision of life-sustaining interventions like dispatcher-assisted cardiopulmonary resuscitation and disaster management. PMID- 30293601 TI - Cardiopulmonary Resuscitation Quality Issues. AB - Much of the current evidence and many of the recent treatment recommendations for increasing survival from cardiac arrest revolve around improving the quality of cardiopulmonary resuscitation during resuscitation. A focus on providing treatments proved beneficial and providing these treatments reliably, using measurement, monitoring, and implementation of quality-improvement strategies, will help eliminate variation in outcomes and provide a foundation from which future improvements in resuscitation care can be developed. Using the knowledge and tools available today will help reduce the ambiguity and variability that exists in resuscitation today and provide the ability to save more lives in communities. PMID- 30293602 TI - Drugs in Out-of-Hospital Cardiac Arrest. AB - Managing out-of-hospital cardiac arrest involves unique challenges, including delays in the initiation of advanced interventions and a limited number of trained personnel on scene. Recent out-of-hospital randomized controlled trials, systematic reviews, and metaanalyses provide key insights into what interventions are best proven to positively impact patient outcomes from out-of-hospital cardiac arrest. We review the literature on medications used in out-of-hospital cardiac arrest and summarize evidence-based guidelines from the American Heart Association that form the basis for most emergency medical services cardiac arrest protocols across the United States. PMID- 30293603 TI - Controversial Issues: Pro Mechanical Cardiopulmonary Resuscitation. AB - High-quality cardiopulmonary resuscitation, in particular chest compressions, is a key aspect of out-of-hospital cardiac arrest (OHCA) resuscitation. Manual chest compressions remain the standard of care; however, the extrication and transport of patients with OHCA undermine the quality of manual chest compressions and risk the safety of paramedics. Therefore, in circumstances whereby high-quality manual chest compressions are difficult or unsafe, paramedics should consider using a mechanical device. By combining high-quality manual chest compressions and judicious application of mechanical chest compressions, emergency medical service agencies can optimize paramedic safety and patient outcomes. PMID- 30293604 TI - Manual Versus Mechanical Cardiopulmonary Resuscitation: A Case Against the Machine. AB - Cardiopulmonary resuscitation (CPR) quality, including chest compression rate, depth, and fraction of hands-on time, is integral to cardiac arrest survival. Introducing mechanized devices to target these measures of quality in the challenging prehospital environment holds great promise. Comparing mechanical to manual CPR, animal models deliver favorable results on markers of perfusion and manikin studies demonstrate improved consistency of high-quality CPR performance with device use. Factoring in real-world application with prospective randomized human trials; however, repeatedly fails to show improvements in patient-centered outcomes and thus cannot be supported by current scientific evidence. PMID- 30293605 TI - Double Sequential Defibrillation. AB - Ventricular fibrillation (VF) is the most commonly encountered arrhythmia following out-of-hospital cardiac arrest. Previous studies have demonstrated early defibrillation and bystander cardiopulmonary resuscitation as essential in reducing patient mortality. What remains a clinical concern, however, is the treatment of patients experiencing VF refractory to defibrillation. Although current guidelines advocate pharmacotherapy for the management of shock refractory VF, double sequential defibrillation has become a popular topic of discussion. This article provides a discourse regarding refractory VF, and a review of double sequential defibrillation literature. Further study is required before the recommendation for widespread implementation of this defibrillation technique. PMID- 30293606 TI - Management of Refractory Ventricular Fibrillation (Prehospital and Emergency Department). AB - Ventricular fibrillation is a life-threatening cardiac arrhythmia that leads to a loss of cardiac function and sudden cardiac death. In this review, we summarize therapeutic interventions and guidelines for providers managing patients with out of-hospital cardiac arrest and refractory ventricular fibrillation in prehospital and emergency settings. Additionally, we review invasive management, including urgent coronary angiography, extracorporeal membrane oxygenation, and novel strategies for managing refractory ventricular fibrillation arrest. Although the majority of patients with refractory VF do not respond to conventional therapy, recent trials of novel strategies demonstrate encouraging results. PMID- 30293607 TI - The Role of Medical Direction in Systems of Out-of-Hospital Cardiac Arrest. AB - Survival for out-of-hospital cardiac arrest (OHCA) is, on average, approximately 10% but considerable variability exists among emergency medical services (EMS) systems across the United States. The medical director of an EMS system has considerable control and influence over outcomes in a system by developing evidence-based protocols and overseeing a robust system of quality assurance. A vision for system-level oversight of care that includes continuous data collection and assessment, personally delivered and constructive feedback to providers, and a constant drive for improvement can result in improvements in both processes and patient-centered outcomes. PMID- 30293608 TI - Critical Care of the Post-Cardiac Arrest Patient. AB - The post-cardiac arrest syndrome is a highly inflammatory state characterized by organ dysfunction, systemic ischemia and reperfusion injury, and persistent precipitating pathology. Early critical care should focus on identifying and treating arrest etiology and minimizing further injury to the brain and other organs by optimizing perfusion, oxygenation, ventilation, and temperature. Patients should be treated with targeted temperature management, although the exact temperature goal is not clear. No earlier than 72 hours after rewarming, prognostication using a multimodal approach should inform discussions with families regarding likely neurologic outcome. PMID- 30293609 TI - Emerging and Future Technologies in Out-of-Hospital Cardiac Arrest Care. AB - The care for victims of out-of-hospital cardiac arrest is evolving and will be influenced by future and emerging technologies that will play a role in the systems of care for these patients. Recent advances in extracorporeal life support and point-of-care ultrasound imaging, both in-hospital and out-of hospital, may offer a therapeutic solution in some systems for patients with refractory or recurrent cardiac arrest. Drones capable of delivering automated external defibrillators to the scene of an out-of-hospital cardiac arrest, advances in digital and mobile technologies to notify and leverage bystander response, and wearable life detection technologies may improve survival.

PMID- 30293616 TI - Changes in renal function after left ventricular assist device placement in pediatric patients: A Pedimacs analysis. AB - BACKGROUND: Renal dysfunction (RD) is prevalent among pediatric patients with advanced heart failure. Data are limited regarding changes in renal function after left ventricular assist device (LVAD) placement in this population. METHODS: Pediatric LVAD recipients enrolled in the Pediatric Interagency Registry for Mechanical Circulatory Support (Pedimacs) between September 19, 2012 and June 30, 2016 were included. Longitudinal changes in renal function were analyzed for the entire cohort as well as subgroups stratified by patient and device characteristics. Logistic regression was used to attempt to identify factors associated with lack of improvement in renal function after LVAD placement. Post LVAD outcomes were assessed using the Kaplan-Meier method. RESULTS: Data from 247 patients from 39 centers were analyzed. Baseline RD (estimated glomerular filtration rate [eGFR] <90 ml/min/1.73 m2) was present in 150 (61%) patients. Overall, eGFR improved post-LVAD, peaking at 1 month post-implant. There was an inverse relationship between baseline eGFR and the degree of improvement at 1 month. Degree of improvement in eGFR at 1 month was not impacted by device type, age, Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) profile, or diagnosis. Failure to normalize renal function at 1 week was correlated with persistent RD at 1 month. Post-implant outcomes did not differ among patients stratified by pre-implant renal function. CONCLUSIONS: Renal function improves post-LVAD placement in pediatric patients regardless of age, diagnosis, illness severity, or device type, with improvement most pronounced in patients with baseline RD. Identifying patients with irreversible renal dysfunction before LVAD placement remains difficult. Pre-LVAD renal function does not appear to impact survival to transplant. PMID- 30293617 TI - Long-term safety and outcome of intravenous treprostinil via an implanted pump in pulmonary hypertension. AB - BACKGROUND: We examined safety and long-term outcomes of intravenous treprostinil administered via the implantable LENUS Pro pump in patients with severe pulmonary hypertension (PH). METHODS: Patients with PH undergoing pump implantation between December 2009 and October 2016 in German referral centers were retrospectively analyzed (end of follow-up: May 2017). The primary objective was to determine long-term safety of the implantable pump. Secondary end points were 3-year survival and prognostic relevance of pre-implantation hemodynamics. RESULTS: We monitored 129 patients (120 with pulmonary arterial hypertension, 1 with PH due to lung diseases, and 8 with inoperable chronic thromboembolic PH) for 260 patient-years (median follow-up, 19 months; interquartile range, 11-34 months). There were 82 complications/peri-procedural events in 60 patients; of these, 57 were serious adverse events (0.60 per 1,000 treatment-days), including 2 periprocedural deaths due to right heart failure. The incidence of complications related to the pump, catheter, infection, and pump pocket per 1,000 treatment days was 0.074, 0.264, 0.032 (3 local infections; no bloodstream infections), and 0.380, respectively. Three-year overall and transplant-free survival were 66.5% and 55.7%, respectively (39 patients died; 16 underwent lung transplantation). Baseline cardiac index independently predicted transplant-free survival (multivariate hazard ratio, 1.90; 95% confidence interval, 1.11-3.28; p = 0.019; n = 95). CONCLUSIONS: Our data suggest that intravenous treprostinil via the LENUS Pro pump in advanced PH is associated with a very low risk of bloodstream infections, but other serious adverse events may occur. Therefore, this therapy needs standardization and should be offered in specialized PH centers only. Further technical advances of the pump system and prospective studies are needed. PMID- 30293618 TI - Frailty and clinical benefits with lung transplantation. AB - BACKGROUND: The Fried frailty phenotype is associated with morbidity and mortality in lung transplant (LTx) candidates, but its clinical application and association with post-transplant outcomes are not well defined. We assessed 2 alternate frailty indices in LTx candidates and evaluated associations of frailty with early post-transplant outcomes and 1-year mortality. METHODS: Frailty was prospectively evaluated in 50 LTx candidates using the Fried and 2 alternate phenotypic indices, one using variables readily available to clinicians and one using variables from an existing data set. Agreement between indices and associations with related measures were assessed to establish validity. The data set index was then applied retrospectively to 221 LTx patients. Post-transplant outcomes were compared between frail and non-frail patients using t-tests and multivariable regression analysis. RESULTS: Frailty prevalence among the 3 indices was 26% to 30%, and the kappa agreement was 0.38 to 0.41. All indices had moderate correlations with London Chest Activity of Daily Living (r = 0.48-0.62) and Short-Physical Performance Battery (r = -0.43 to -0.52). In the retrospective cohort, frail LTx candidates had a worse St. George's Respiratory Questionnaire total score (73 +/- 12vs 62 +/- 12, p < 0.001). Frail candidates had a larger improvement with transplant in the St. George's Respiratory Questionnaire (-52 +/ 19vs -43 +/- 18, p = 0.002) and 6-minute walk distance (191 +/- 119vs 129 +/- 94m, p = 0.001). Frailty was not associated with hospital length of stay or 1 year mortality. CONCLUSIONS: There was good construct validity and acceptable agreement among the frailty indices. Despite significant disability pre transplant, frail LTx candidates derived significant benefit with transplantation.

AB - Walking confers numerous health benefits, particularly for middle-aged and older patients with diabetes and metabolic syndrome. Nevertheless, it brings a risk of injurious falls, especially among populations with diabetes and metabolic syndrome-related distal neuromuscular decline and frank neuropathy. Those who stand to benefit most from walking are at greatest risk. Development of practical clinical tools to more precisely quantify neuromuscular function and link it to mobility outcomes will help clinicians target interventions toward those at risk for falls. Electrodiagnosis, with inclusion of several newer techniques, serves as a promising tool for objective evaluation of distal neuromuscular function.

It may also help to manage or track disease progression. Mapping the extent of subclinical disease may guide the clinician to supportive interventions. There is considerable interest in establishing electrodiagnostic biomarkers to monitor disease progression.

PMID- 30293624 TI - Planning Interventions to Treat Brachial Plexopathies. AB - This article reviews the electrodiagnosis of brachial plexus injury, factors that predict outcome, the utility electrodiagnostic evaluation of potential nerve donors, and commonly used surgical interventions. Electrodiagnostic evaluation begins with a detailed understanding of brachial plexus anatomy and uses a complement of motor and sensory nerve conduction studies and needle electromyography to determine the location of injury and predict severity. Several factors are used to predict prognosis. In injuries with poor prognosis, surgical intervention is indicated. Nerve transfers are increasingly employed to improve functional outcomes. Electrodiagnosis is key to evaluating the viability of potential nerve donors. PMID- 30293626 TI - Predicting Recovery from Peripheral Nerve Trauma. AB - We enhance the value of electrodiagnostic studies when we discuss prognosis after nerve injuries. Nerves are variable in their mechanism, location, and pathophysiology of injury. Several factors currently known to influence prognosis include the nature of the nerve trauma, amount of axon loss, recruitment in muscles supplied by the nerve, extent of demyelination, and distance to reinnervate functional muscles. Generally, findings of large motor responses, intact recruitment in muscles supplied distal to the injury, and the presence of a conduction block are associated with a better prognosis. This article discusses nerve-specific information as well. PMID- 30293625 TI - Minimizing Risk of Cancer Therapeutics. AB - Cancer treatments continue to advance the management and survival of patients. However, use of these regimens can lead to significant side effects both temporary and permanent. Neuromuscular side effects include chemotherapy-induced peripheral neuropathy and radiation fibrosis syndrome. At this time, the only way to resolve the neurotoxicity is reduction or discontinuation of the offending agent. In an attempt to limit interference with a patient's chemotherapy regimen and mitigate chronic disability, efforts for early detection through subjective clinical evaluations and objective measurement with electrodiagnostics can help to improve symptom management and minimize alteration in treatment. PMID- 30293627 TI - Electrodiagnosis in the Patient with Metabolic Syndrome: Adding Value to Patient Care. AB - Patients with metabolic syndrome are at increased risk of peripheral neuropathy; entrapment neuropathies, such as carpal tunnel syndrome; and spine disease that can lead to radiculopathy or spinal stenosis. Electrodiagnostic studies are a valuable part of patient care in this population. They can confirm suspected diagnoses, uncover additional conditions, and lead to the diagnosis of other causes of neuropathy that require treatment. By assessing the severity of neuropathy, patients at high risk for falls, functional decline, and foot ulcers are identified to guide prevention, treatment, and patient education. PMID- 30293628 TI - Guiding Treatment for Carpal Tunnel Syndrome. AB - Making the correct carpal tunnel syndrome diagnosis is the most important step in treatment. Electrodiagnosis can confirm carpal tunnel syndrome and eliminate mimicking diseases from the differential. Treatment should provide satisfactory pain relief and protection of the median nerve from further deterioration. Electrodiagnosis testing provides information on focal median mononeuropathy at the wrist that could be used to classify carpal tunnel syndrome from mild to severe. The information obtained can help patients to understand and choose treatment in a patient-centered fashion. False positives can cause more harm than false negatives in the case of carpal tunnel syndrome. PMID- 30293629 TI - Steering Peripheral Neuropathy Workup.

PMID- 30293630 TI - Elucidating the Cause of Pelvic Pain. AB - Chronic pelvic pain is a common condition. Establishing a diagnosis can be complicated by the interplay between various organ systems, including urologic, gynecologic, gastrointestinal, neurologic, endocrinological, psychological, and musculoskeletal. Frequently, the patient will have seen multiple providers and undergone multiple tests, as well as invasive procedures, before the musculoskeletal system is even considered in the differential diagnosis. Typically, the musculoskeletal and nervous systems become suspected culprits only once all other potential etiologies have been eliminated. PMID- 30293631 TI - Guiding Treatment for Foot Pain. AB - In the electrodiagnostic (EDX) approach of the patient who presents with foot pain, numbness, and/or tingling, it is important to consider a broad differential diagnosis of both neuropathic and nonneuropathic conditions, including focal and systemic causes.

PMID- 30293634 TI - Assessing outpatient follow-up care compliance, complications, and sequelae in children hospitalized for isolated traumatic abdominal injuries. AB - BACKGROUND: Currently there is limited knowledge on compliance with follow-up care in pediatric patients after abdominal trauma. The Indiana Network for Patient Care (INPC) is a large regional health information exchange with both structured clinical data (e.g., diagnosis codes) and unstructured data (e.g., provider notes). The objective of this study is to determine if regional health information exchanges can be used to evaluate whether patients receive all follow up care recommended by providers. METHODS: We identified 61 patients treated at a Pediatric Level I Trauma Center who were admitted for isolated abdominal injuries. We analyzed medical records for two years following initial hospital discharge for injury using the INPC. The encounters were classified by the type of encounter: outpatient, emergency department, unplanned readmission, surgery, imaging studies, and inpatient admission; then further categorized into injury- and non-injury-related care, based on provider notes. We determined compliance with follow-up care instructions given at discharge and subsequent outpatient visits, as well as the prevalence of complications and sequelae. RESULTS: After reviewing patient records, we found that 78.7% of patients received all recommended follow-up care, 6.6% received partial follow-up care, and 11.5% did not receive follow-up care. We found that 4.9% of patients developed complications after abdominal trauma and 9.8% developed sequelae in the two years following their initial hospitalization. CONCLUSIONS: Our findings suggest that health information exchanges such as the INPC are useful in evaluation of follow up care compliance and prevalence of complications/sequelae after abdominal trauma in pediatric patients.

PMID- 30293638 TI - Factors Associated with Breastfeeding Initiation and Continuation: A Meta Analysis. AB - OBJECTIVE: To use a quantitative approach to evaluate the literature for quantity, quality, and consistency of studies of maternal and infant characteristics in association with breastfeeding initiation and continuation, and to conduct a meta-analysis to produce summary relative risks (RRs) for selected factors. STUDY DESIGN: A systematic review using PubMed and CINAHL through March 2016 was conducted to identify relevant observational studies in developed nations, reporting a measure of risk for 1 or more of 6 quantitatively derived, high impact factors in relation to either breastfeeding initiation or continuation. One author abstracted data using a predesigned database, which was reviewed by a second independent author; data evaluation and interpretation included all co-authors. These factors were summarized using standard meta analysis techniques. RESULTS: Six high impact factors were identified (smoking [39 papers], mode of delivery [47 papers], parity [31 papers], dyad separation [17 papers], maternal education [62 papers], and maternal breastfeeding education [32 papers]). Summary RR from random-effects models for breastfeeding initiation were highest for high vs low maternal education (RR 2.28 [95% CI 1.92-2.70]), dyad connection vs not (RR 2.01 [95% CI 1.38-2.92]), and maternal nonsmoking vs smoking (RR = 1.76 [95% CI 1.59-1.95]); results were similar for breastfeeding continuation. CONCLUSIONS: Despite methodological heterogeneity across studies, relatively consistent results were observed for these perinatally identifiable factors associated with breastfeeding initiation and continuation, which may be informative in developing targeted interventions to provide education and support for successful breastfeeding in more families.

RESULTS: Thoraco-abdominal abnormalities were identified in 6 of 368 (1.6%) subjects with a minimum prevalence of 1 in 60 Clinical Registry Investigating BBS participants. Diverse laterality defects were observed suggesting that the underlying ciliopathy randomly alters embryonic left-right axis orientation. Congenital heart disease, common in heterotaxy, was present in 2 subjects. Additional defects, uncommonly reported in BBS, were observed in the central nervous, genitourinary, gastrointestinal, and musculoskeletal systems in the subjects. No BBS genotype was favored in the cohort. One subject had genetic and clinical phenotype diagnostic of both primary ciliary dyskinesia and BBS. CONCLUSIONS: The variety of thoraco-abdominal abnormalities in BBS suggests the pleiotropic nature of these anomalies is not confined to a single pattern or genotype. Clinicians providing care to individuals with BBS should consider the increased prevalence of thoraco-abdominal anomalies in BBS. Individuals with features suggestive of other ciliopathies, such as primary ciliary dyskinesia, should undergo further evaluation for additional genetic disorders. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02329210. PMID- 30293641 TI - Risk of Developmental Disorders in Children of Immigrant Mothers: A Population Based Data Linkage Evaluation. AB - OBJECTIVES: To evaluate the prevalence and risks of developmental disability (autism spectrum disorder, intellectual disability, and cerebral palsy) in Western Australian children of different groups of foreign-born women. STUDY DESIGN: Western Australian population-based linked data of 764 749 singleton live births from 1980 to 2010 were used to compare disability outcomes among children of foreign-born, Australian-born non-Indigenous, and Indigenous women. The risk of disability was assessed using multinomial logistic regression. RESULTS: Overall, the prevalence of any disability was lowest for the children of foreign born mothers. From 1980 to 1996 but not from 1997 to 2010, children born to mothers from foreign-born low-income countries had an increased relative risk of autism spectrum disorder with intellectual disability, and children born to foreign-born mothers from upper-middle-income countries had an increased risk of cerebral palsy with intellectual disability. After adjusting for smoking, the relative risks of intellectual disability and cerebral palsy with intellectual disability were markedly decreased in children of Australian-born Indigenous mothers. CONCLUSIONS: Although we did not find among children born to foreign born women an increased prevalence across all the measured developmental outcomes, we did observe an increased risk of autism spectrum disorder with intellectual disability and cerebral palsy with intellectual disability for mothers of some foreign-born groups. Our findings related to smoking in the Indigenous population underscore its possible role on the causal pathway to intellectual disability. Maternal migration is considered a factor on the causal pathway to intellectual disability. Maternal migration may be either a risk or a protective factor on the causal pathway to developmental disabilities and the direct role of migration is inconclusive in our study. PMID- 30293642 TI - Estimating Risk of Pneumonia in a Prospective Emergency Department Cohort. AB - OBJECTIVE: To improve the prediction of pediatric pneumonia by developing a series of models based on clinically distinct subgroups. We hypothesized that these subgroup models would provide superior estimates of pneumonia risk compared with a single pediatric model. STUDY DESIGN: We conducted a secondary analysis of a prospective cohort being evaluated for radiographic pneumonia in an urban pediatric emergency department (ED). Using multivariate modeling, we created 4 models across subgroups stratified by age and presence of wheezing to predict the risk of pneumonia. RESULTS: A total of 2351 patients were included in the study. In this series, the prevalence of pneumonia was 8.5%, and 21.6% were hospitalized. The highest prevalence of pneumonia was in children aged >2 years without wheezing (13.3%). Children aged <2 years with wheezing had the lowest prevalence of pneumonia (4.0%). The most accurate model was for children aged <2 years with wheezing (area under the curve [AUC], 0.80), and the poorest performing model was for those aged <2 years without wheezing (AUC, 0.64). The AUC of a combination of the 4 subgroup models was 0.76 (95% CI, 0.72-0.80). The precision of the models' estimates (expected vs observed) was +/- 3.7%. CONCLUSIONS: Using 4 complementary prediction models for pediatric pneumonia, an accurate risk of pneumonia can be calculated. These models can provide the basis for clinical decision making support to guide the use of chest radiographs and promote antibiotic stewardship. PMID- 30293643 TI - FMISO-PET-based lymph node hypoxia adds to the prognostic value of tumor only hypoxia in HNSCC patients. AB - PURPOSE: This secondary analysis of the prospective study on repeat [18F]fluoromisonidazole (FMISO)-PET in patients with locally advanced head and neck squamous cell carcinomas (HNSCC) assessed the prognostic value of synchronous hypoxia in primary tumor (Tu) and lymph node metastases (LN), and evaluated whether the combined reading was of higher prognostic value than that of primary tumor hypoxia only. METHODS: This analysis included forty-five LN positive HNSCC patients. FMISO-PET/CTs were performed at baseline, weeks 1, 2 and 5 of radiochemotherapy. Based on a binary scale, Tu and LN were categorized as hypoxic or normoxic, and two prognostic parameters were defined: Tu-hypoxia (independent of the LN oxygenation status) and synchronous Tu-and-LN-hypoxia. In fifteen patients with large LN (N = 21), additional quantitative analyses of FMISO-PET/CTs were performed. Imaging parameters at different time-points were correlated to the endpoints, i.e., locoregional control (LRC), local control (LC), regional control (RC) and time to progression (TTP). Survival curves were estimated using the cumulative incidence function. Univariable and multivariable Cox regression was used to evaluate the prognostic impact of hypoxia on the endpoints. RESULTS: Synchronous Tu-and-LN-hypoxia was a strong adverse prognostic factor for LC, LRC and TTP at any of the four time-points (p <= 0.004), whereas Tu-hypoxia only was significantly associated with poor LC and LRC in weeks 2 and 5 (p <= 0.047), and with TTP in week 1 (p = 0.046). The multivariable analysis confirmed the prognostic value of synchronous Tu-and-LN-hypoxia regarding LRC (HR = 14.8, p = 0.017). The quantitative FMISO-PET/CT parameters correlated with qualitative hypoxia scale and RC (p < 0.001, p <= 0.033 at week 2, respectively). CONCLUSIONS: This secondary analysis suggests that combined reading of primary tumor and LN hypoxia adds to the prognostic information of FMSIO-PET in comparison to primary tumor assessment alone in particular prior and early during radiochemotherapy. Confirmation in ongoing trials is needed before using this marker for personalized radiation oncology.

PMID- 30293644 TI - Complications after stereotactic radiosurgery for brain metastases: Incidences, correlating factors, treatments and outcomes. AB - BACKGROUND AND PURPOSE: Complications after stereotactic radiosurgery (SRS) for brain metastases (BMs) were analyzed in detail using our database including nearly 3000 BM patients. MATERIALS AND METHODS: This was an institutional review board-approved, retrospective cohort study using our prospectively accumulated database including 3271 consecutive patients who underwent gamma knife SRS for BMs during the 1998-2016 period. Excluding four patients lost to follow-up, 112 with three-staged treatment and 189 with post-operative irradiation, 2966 who underwent a single-session of SRS only as radical irradiation were studied. RESULTS: The overall median survival time after SRS was 7.8 (95% CI; 7.4-8.1) months. Post-SRS complications occurred in 86 patients (2.9%) 1.9-211.4 (median; 24.0, IQR; 12.0-64.6) months after treatment. RTOG neurotoxicity grades were 2, 3 and 4 in 58, 25 and 3 patients, respectively. Cumulative incidences determined with a competing risk analysis were 1.4%, 2.2%, 2.4%, 2.6% and 2.9% at the 12th, 24th, 36th, 48th and 60th post-SRS month, respectively. Among various pre-SRS clinical factors and radiosurgical parameters, multivariable analyses demonstrated solitary tumor (Adjusted HR; 0.584, 95% CI; 0.381-0.894, p = 0.0133), controlled primary cancer (Adjusted HR; 2.595, 95% CI; 1.646-4.091, p < 0.0001), no extra-cerebral metastases (Adjusted HR; 1.608, 95% CI; 1.028-2.514, p = 0.0374), KPS >=80% (Adjusted HR; 2.715, 95% CI; 1.245-5.924, p = 0.0121) and largest tumor volume >=3.3 cc (Adjusted HR; 0.516, 95% CI; 0.318-0.836, p = 0.0072) to be independently significant predictors of a higher incidence of complications. CONCLUSION: The post-SRS complication incidence is acceptably low (2.9%). Meticulous long-term follow-up after SRS is crucial for all patients.

AB - On 25 July 2018, the Court of Justice of the European Union (CJEU) ruled that gene-specific mutagenesis must be regulated as genetically modified organism (GMO) technologies. However, the costs to agricultural research and development (R&D) innovation will be staggering, not to mention the brain drain to other countries. As a result, Europe can now be known as the deathplace of agricultural breeding innovations. PMID- 30293647 TI - Perinatal Nutrition and Programmed Risk for Neuropsychiatric Disorders: A Focus on Animal Models. AB - Maternal nutrition is critically important for fetal development. Recent human studies demonstrate a strong connection between diet during pregnancy and offspring risk for neuropsychiatric disorders including depression, anxiety, and attention-deficit/hyperactivity disorder. Animal models have emerged as a crucial tool for understanding maternal nutrition's contribution to prenatal programming and the later development of neuropsychiatric disorders. This review highlights preclinical studies examining how maternal consumption of the three macronutrients (protein, fats, and carbohydrates) influence offspring negative valence behaviors relevant to neuropsychiatric disorders. We highlight the translational aspects of animal models and so examine exposure periods that mirror the neurodevelopmental stages of human gestation. Because of our emphasis on programmed changes in neurobehavioral development, studies that continue diet exposure until assessment in adulthood are not discussed. The presented research provides a strong foundation of preclinical evidence of nutritional programming of neurobehavioral impairments. Alterations in risk assessment and response were observed alongside neurodevelopmental impairments related to neurogenesis, synaptogenesis, and synaptic plasticity. To date, the large majority of studies utilized rodent models, and the field could benefit from additional study of large-animal models. Additional future directions are discussed, including the need for further studies examining how sex as a biological variable affects the contribution of maternal nutrition to prenatal programming. PMID- 30293648 TI - Use of processing fluids and serum samples to characterize porcine reproductive and respiratory syndrome virus dynamics in 3 day-old pigs. AB - Collection of serum samples of pigs at weaning to monitor for porcine reproductive and respiratory syndrome virus (PRRSV) has become a common practice to determine PRRSV herd infection status. Diagnostic sensitivity of this practice is low in herds undergoing PRRSV elimination once prevalence of infection is near zero. Thus, the goal of this study was to characterize the dynamics of PRRSV infection in 3 day-old pigs overtime using serum and serosanguineous fluids obtained as part of castration and tail docking practices (processing fluids (PF)). Secondary goal was to estimate sensitivity and specificity of PF in the 3 day old population. A 6000 breed-to-wean sow herd was monitored every three weeks for 23 weeks after a PRRSV outbreak by collecting both PF and individual serum samples from all pigs in the selected litters. Out of the 77 litters tested, 23 (29.8%) were identified as positive using the PF and the serum samples, with a Cohen's kappa statistic of 0.81 (95% CI: 0.59-1) between the results obtained in each sample type. The sensitivity and specificity of the PF relative to the results in serum was 87% (95% CI: 66%-97%) and 94% (95% CI: 85%-99%) respectively. The percentage of PRRSV positive litters decreased over time and litters from gilts were more likely to test positive than those from older sows. Overall, the study demonstrates that PF can be a convenient and reliable specimen to monitor PRRSV infection in breeding herds. PMID- 30293649 TI - Nutrition and oral health. AB - To maintain health, the human body needs daily nourishment in the form of carbohydrates, proteins and minerals. The associations between oral health conditions, dietary practices and nutritional status, and general health status are complex with many interrelating factors. Inadequate nutrition can affect the oral health including dental caries, periodontal diseases, diseases of oral mucosa and infectious diseases. Compromised oral health can alter food choices and negatively impact food intake leading to suboptimal nutritional status which can lead to chronic systemic diseases. Recognizing and treating oral health and nutrition problems are important in improving the health and quality of life. PMID- 30293650 TI - Frequency of Complications Including Death from Coronary Artery Bypass Grafting in Patients With Hepatic Cirrhosis. AB - Advanced liver disease is a risk factor for cardiac surgery. However, liver dysfunction is not included in cardiac risk assessment models. We sought to identify trends in utilization, complications, and outcomes of patients with cirrhosis who underwent coronary artery bypass graft surgery (CABG). Using the National Inpatient Sample database, we identified patients with cirrhosis who underwent CABG from 2002 to 2014. Propensity-score matching was used to identify differences in in-hospital mortality and postoperative complications in cirrhosis and noncirrhosis patients. We identified a total of 698,799 CABG admissions of which 2,231 (0.3%) had cirrhosis (mean age 63.6 +/- 9.6 years, 74% men, 63% white, mean Charlson co-morbidity index 3.3 +/- 1.8). Cardiopulmonary bypass was used in 71% of patients. Mean length of stay was 13.7 +/- 11.4 days and hospitalization cost $67,744.6 +/- 58,320.4. One or more complications occurred in 44% of cases. After propensity-score matching, patients with cirrhosis had a higher rate of complications (43.9% vs 38.93%; p < 0.001) and in-hospital mortality (7.2% vs 4.07%; p < 0.001) than noncirrhosis patients. On multivariate analysis, cirrhosis and ascites were associated with increased in-hospital mortality (odds ratio 2.87; 95% confidence intervals 2.37 to 3.48) and postoperative complications (odds ratio 5.11; 95% confidence intervals 3.88 to 6.72). In conclusion, patients with cirrhosis constitute a small portion of patients who underwent CABG in the United States but have a higher rate of complications and in-hospital mortality compared with noncirrhosis patients. In hospital mortality remains high for this subset of patients but has decreased in recent years. PMID- 30293652 TI - Right-Sided Heart Structural and Functional Remodeling in Mitral Regurgitation Secondary to Mitral Valve Prolapse. AB - Preoperative evaluation of the mitral valve but also of tricuspid valve and right ventricular (RV) function is mandatory in primary mitral regurgitation (MR) secondary to mitral valve prolapse (MVP). Tricuspid annulus (TA) diameter plays a pivotal role in the surgical decision to perform preventive combined tricuspid valve annuloplasty. Cardiac magnetic resonance (CMR) is the gold standard for the assessment of RV size and function. Based on 70 consecutive patients (17 women; mean age 64 +/- 12) with severe MR secondary to MVP referred for CMR, we sought to assess RV geometry and function and TA dimensions and to study the interaction between TA dilatation and right-sided cardiac chambers. Frequency of RV dilatation, RV systolic dysfunction, and TA dilatation (TA diameter >= 40 or 21 mm/m2) were 11%, 51%, and 49%, respectively. Left ventricular (LV) end-diastolic volume index was the only independent predictor of RV dilatation. Presence of symptoms, larger LV end-diastolic volume index, and LV ejection fraction <60% were independently associated with RV dysfunction. Absolute TA diameter was 36 +/ 6 mm and TA diameter index was 20 +/- 3 mm/m2. Reproducibility TA diameter measurement was excellent (coefficient of variation <=10%). TR velocity >220 cm/s (odds ratio = 20.17; [3.57 to 113.90]; p = 0.001 and right atrial volume index >= 38 ml/m2 (odds ratio = 13.44; [3.57 to 50.54]; p = 0.0001) were independent predictors of TA diameter >=40 or 21 mm/m2. CMR provides accurate right-sided cardiac chambers assessment and may help surgical planning of concomitant tricuspid valve annuloplasty before mitral valve repair in severe MR secondary to MVP. In conclusion, TA dilatation, RV enlargement, and dysfunction are related to pulmonary pressure and left-sided cardiac chambers enlargement, reflecting the long-standing consequences of severe MR. PMID- 30293651 TI - Meta-analysis of Prevalence and Risk Factors for Delirium After Transcatheter Aortic Valve Implantation. AB - Delirium is a severe and common complication following transcatheter aortic valve implantation (TAVI). We sought to identify the prevalence and risk factors associated with the development of postprocedural delirium in patients aged over 60 years who underwent elective TAVI for aortic stenosis. Overall, 1,051 articles were searched, from which 9 studies were included. The prevalence of delirium following TAVI was higher in studies that assessed delirium for a minimum of 3 consecutive days (24.9%) compared with the studies that did not (2%). There were large effect sizes (d > 0.8) for 3 risk factors: acute kidney injury (odds ratio [OR] 5, p < 0.001), transapical approach (OR 4, p < 0.001) and carotid artery disease (OR 4, p < 0.001), whilst small effect sizes were found for a history of atrial fibrillation, prior stroke/transient ischemic attack, peripheral artery disease, hypertension, and prior cognitive impairment. In conclusion, 23% of patients 60 years and over who underwent TAVI experience delirium, a preventative cause of cognitive impairment and dementia. Recognition of risk factors for delirium after TAVI, such as a history of carotid artery disease, development of acute kidney injury, or use of a transapical approach, provides an opportunity to implement proven delirium preventative measures. PMID- 30293653 TI - Influence of Baseline Platelet Count on Outcomes in Patients With Venous Thromboembolism (from the COMMAND VTE Registry). AB - The influence of thrombocytopenia on the long-term clinical outcomes has not been thoroughly evaluated in patients with venous thromboembolism (VTE). This study sought to elucidate association of baseline thrombocytopenia with bleeding, recurrent VTE, and mortality risk. We evaluated the influence of baseline thrombocytopenia among 3,012 patients whose baseline platelet counts were available in the COMMAND VTE Registry in Japan with a median follow-up period of 1,219 days. Baseline thrombocytopenia was classified as follows: mild: 100,000 to 150,000/MUl; moderate: 50,000 to 99,999/MUl; and severe: <50,000/MUl. The primary outcome measurement was International Society of Thrombosis and Hemostasis major bleeding, and the secondary outcome measurements were recurrent VTE and all-cause death. There were 167 patients (5.5%) with moderate or severe thrombocytopenia (moderate: 144 patients and severe: 23 patients), 523 patients (17.4%) with mild thrombocytopenia, and 2,322 patients (77.1%) without thrombocytopenia. The cumulative 5-year incidence of major bleeding was markedly higher in patients with moderate or severe thrombocytopenia (moderate or severe 29.4% vs mild: 14.1% vs no thrombocytopenia: 10.6%, p <0.001). After adjusting the confounders, the risk of or thrombocytopenia relative to no thrombocytopenia for major bleeding remained significant (adjusted hazard ratio [HR] 2.15, 95% confidence interval [CI] 1.43 to 3.13, p <0.001). The excess risk of moderate or severe thrombocytopenia relative to no thrombocytopenia was also significant for mortality (adjusted HR 1.54, 95% CI 1.18 to 1.97, p = 0.002), but the risk was neutral for recurrent VTE (adjusted HR 1.05, 95% CI 0.55 to 1.81, p = 0.87). In conclusion, VTE patients with baseline moderate or severe thrombocytopenia had higher risk for major bleeding events and mortality without significant excess risk for recurrent VTE events. PMID- 30293654 TI - Validation of the 2014 European Society of Cardiology Sudden Cardiac Death Risk Prediction Model Among Various Phenotypes in Japanese Patients With Hypertrophic Cardiomyopathy. AB - Risk stratification for sudden cardiac death (SCD) is essential in the management of hypertrophic cardiomyopathy (HC). The 2014 European Society of Cardiology SCD risk prediction model (Risk-SCD) is a novel risk scoring system; however, whether it can be applied to Japanese HC and its usefulness among various HC phenotypes remain unclear. The aim of this study was to validate the Risk-SCD model in Japanese HC, and to evaluate its usefulness among various HC phenotypes. We studied 370 consecutive Japanese HC patients evaluated for primary SCD prevention at our tertiary referral center. The Risk-SCD model was validated in 289 HC patients with ejection fraction (EF) >=50% (including left ventricular outflow tract obstruction [LVOTO], mid ventricular obstruction [MVO], apical hypertrophy, and nonobstructive phenotypes), and 81 end-stage HC patients (EF <50%). The end point of the study was SCD or an equivalent event (appropriate implantable cardioverter defibrillator therapy or successful resuscitation after cardiac arrest). Thirty-one SCD events were observed during a median follow-up of 5.2 (interquartile range 3.5 to 6.9) years. The Risk-SCD model showed improved risk prediction in HC with EF >=50% compared with the previous 2011 American College of Cardiology Foundation/American Heart Association and 2003 American College of Cardiology/European Society of Cardiology guideline approaches (number needed to treat = 3.8 at Risk-SCD >6%) regardless of phenotypes; LVOTO, MVO, apical, and nonobstructive, but misclassified SCD risk in end-stage HC. In the current external validation of the Risk-SCD model in Japanese HC, the model improved SCD prediction compared with previous approaches, and was also shown to be useful in LVOTO, MVO, apical, and nonobstructive phenotypes. PMID- 30293655 TI - Normalization of N-Terminal Pro-B-Type Natriuretic Peptide After Cardiac Surgery Among Children With Tetralogy of Fallot. AB - The aim of this study was to temporally measure N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels over a period of 18 months after corrective surgery among children with tetralogy of Fallot (TOF) and to explore how commonly used pharmaceuticals (i.e., spironolactone and digoxin) might affect the normalization pattern. This retrospective study included 136 children with a median age of 7 months who underwent cardiac surgery for TOF. NT-proBNP level was measured at 1, 3, 6, 12, and 18 months after the surgery. Normalization of NT-proBNP was defined as an NT-proBNP level <=250 pg/ml. The commonly used pharmaceuticals spironolactone and digoxin after discharge were collected. The normalization pattern, normalization time, and potential influence of the pharmaceuticals were determined. The rate of normalization was 24.2% (95% confidence interval [CI] 8.58% to 68.4%) per 100 person-days. Kaplan-Meier survival analysis showed a median normalization time of 517 (95% CI 429.6 to 604.3) days. The children whose NT-proBNP level did not normalize had a significantly higher readmission rate than those whose NT-proBNP level normalized (19.0% vs 2.8%, p = 0.018). Multivariable logistic regression models confirmed that the regular users of spironolactone, alone (odds ratio = 1.45, 95% CI 1.15 to 1.83) or in combination with digoxin (odds ratio = 1.28, 95% CI 1.03 to 1.58), had markedly faster recovery trajectories for measures of NT-proBNP than the irregular users of both. In conclusion, NT-proBNP normalization after cardiac surgery for TOF is a lengthy process, and irregular use of spironolactone could lead to failure in recovery and hospital readmission. PMID- 30293656 TI - Trends in Incidence, Characteristics, and In-Hospital Outcomes of Patients Presenting With Spontaneous Coronary Artery Dissection (From a National Population-Based Cohort Study Between 2004 and 2015). AB - Though infrequent, spontaneous coronary artery dissection (SCAD) is increasingly recognized as an important cause of acute coronary syndrome (ACS), particularly in young healthy women. However, the population-based incidence of SCAD is unknown. We evaluated the incidence, patient characteristics, clinical characteristics, and mortality of SCAD-related hospitalizations using data from a national population-based cohort study from January 1, 2004, to September 30, 2015. In 13,573,200 patients who presented with an acute coronary syndrome, 66,360 (0.49%) of patients were diagnosed with SCAD. The mean age was 63.1 +/- 13.2 years and 44.2% were women. In-hospital mortality of SCAD patients was 4.2%: 5.03% in females and 3.55% in males (p < 0.001). In conclusion, SCAD is an uncommon diagnosis that should be considered in males and older patients in addition to females presenting with ACS. Most SCAD patients today are managed medically. In-hospital mortality is comparable to that of other patients who present with ACS. PMID- 30293657 TI - Chronic Kidney Disease as a Possible Predictor of Left Atrial Thrombogenic Milieu Among Patients with Nonvalvular Atrial Fibrillation. AB - Patients with chronic kidney disease (CKD) experiencing atrial arrhythmia are hypothesized to have elevated CHADS2 and CHA2DS2-VASc scores, thereby predisposed to left atrial (LA) thrombus formation and subsequent thromboembolism. We examined possible association of LA thrombogenic milieu (TM) with CKD in patients with nonvalvular atrial fibrillation. A total of 581 patients (181 women; mean age, 67 years) who underwent transesophageal echocardiography were examined. Patients were divided into 4 groups based on the estimated glomerular filtration rate (eGFR) (ml/min/1.73 m2): eGFR >=90 (n = 29), 60<= eGFR <90 (n = 329), 30<= eGFR <60 (n = 209), and eGFR <30 (n = 14). TM was defined as the presence of LA thrombus, dense spontaneous echo contrast, or LA appendage velocity <=25 cm/s. Of 581 patients, 147 (25%) had TM. The prevalence of TM increased with decreasing eGFR (4%, 18%, 36%, and 86% for each group, p <0.001). Similar trends were observed for some of the clinical and echocardiographic variables including CHA2DS2-VASc score and LA size. Multivariate logistic regression analysis revealed that every 10 ml/min/1.73 m2 decrement in eGFR was a significant independent correlate of TM (odds ratio 0.80, p = 0.005), along with nonparoxysmal atrial fibrillation (AF) (odds ratio 0.45, p = 0.004), higher CHA2DS2-VASc score (odds ratio 1.24, p = 0.012), every 5 ml/m2 increment in LA volume index (odds ratio 1.57, p <0.001), and every 10% decrement in left ventricular ejection fraction (odds ratio 0.51, p <0.001). In conclusion, CKD may be a significant risk factor for LA thrombus formation in patients with nonvalvular atrial fibrillation. PMID- 30293658 TI - Long-Term Left Ventricular Remodeling of Patients With Hypertrophic Cardiomyopathy. AB - In hypertrophic cardiomyopathy (HC), a process of left ventricular (LV) remodeling carrying an adverse prognosis has been described. Conversely, a gradual and benign LV wall thinning has been suggested but never investigated. Therefore, we studied a HC cohort over a long period of time to evaluate the occurrence of a LV remodeling with a benign clinical course. Data of HC patients aged 18 to 65 years and without any condition known to influence LV remodeling were analyzed over a mean follow-up of 7.6 +/- 5.7 years. Of 231 HC patients (65% males, mean age 46 +/- 12 years), 47 (20%) developed LV remodeling, of whom 23 (10%) had a thinning >=15% of LV maximal wall thickness from baseline without systolic dysfunction (MWT thinning); 13 (6%) progressed to a LV ejection fraction <50% (end-stage HC) and 11 (5%) developed an apical aneurysm. Follow-up length (odds ratio 1.07, 95% confidence interval 1.00 to 1.15, p = 0.06) and maximal LV wall thickness at baseline (odds ratio 1.14, 95% confidence interval 1.04 to 1.25, p = 0.004) were the main predictors of MWT thinning. Compared with patients with end-stage HC and apical aneurysm, those with MWT thinning showed lower HC related morbidity (92% and 36% vs 22%, p = 0.003) and mortality (31% and 27% vs 4%, p = 0.02). Furthermore, they showed a combined HC-related morbidity and mortality similar to patients without LV remodeling (incidence 29/1000 vs 26/1000 patient-year, p = 0.77). In conclusion, a process of LV wall thinning with a benign outcome can occur over the long term in patients with HC. The prognostic importance of LV remodeling varies in relation to the different changes in LV morphology and function. PMID- 30293659 TI - Diversity of Quaternary Structures Regulates Nuclear Receptor Activities. AB - Nuclear receptors (NRs) form homo- and/or heterodimers as central scaffolds of multiprotein complexes, which activate or repress gene transcription to regulate development, homeostasis, and metabolism. Recent studies on NR quaternary structure reveal novel mechanisms of receptor dimerization, the existence of tetrameric chromatin-bound NRs, and previously unanticipated protein protein/protein-DNA interactions. PMID- 30293660 TI - Physiological and biochemical responses of a coralline alga and a sea urchin to climate change: Implications for herbivory. AB - Direct responses to rising temperatures and ocean acidification are increasingly well known for many single species, yet recent reviews have highlighted the need for climate change research to consider a broader range of species, how stressors may interact, and how stressors may affect species interactions. The latter point is important in the context of plant-herbivore interactions, as increasing evidence shows that increasing seawater temperature and/or acidification can alter algal traits that dictate their susceptibility to herbivores, and subsequently, community and ecosystem properties. To better understand how marine rocky shore environments will be affected by a changing ocean, in the present study we investigated the direct effects of short-term, co-occurring increased temperature and ocean acidification on a coralline alga (Jania rubens) and a sea urchin herbivore (Echinometra lucunter) and assessed the indirect effects of these factors on the algal-herbivore interaction. A 21-day mesocosm experiment was conducted with both algae and sea urchins exposed to ambient (24 degrees C, Low CO2), high-temperature (28 degrees C, Low CO2), acidified (24 degrees C, High CO2), or high-temperature plus acidified (28 degrees C, High CO2) conditions. Algal photosynthesis, respiration, and phenolic content were unaffected by increased temperature and CO2, but calcium carbonate content was reduced under high CO2 treatments in both temperatures, while total sugar content of the algae was reduced under acidified, lower temperature conditions. Metabolic rates of the sea urchin were elevated in the lower temperature, high CO2 treatment, and feeding assays showed that consumption rates also increased in this treatment. Despite some changes to algal chemical composition, it appears that at least under short-term exposure to climate change conditions, direct effects on herbivore metabolism dictated herbivory rates, while indirect effects caused by changes in algal palatability seemed to be of minor importance. PMID- 30293661 TI - Hierarchical structuring of genetic variation at differing geographic scales in the cultivated sugar kelp Saccharina latissima. AB - The cultivation of macroalgae for biofuels, food and fertilisers has increased dramatically in recent years. The demand for such algal-derived products means that large scale cultivation in coastal waters will become necessary to provide sufficient algal biomass. As part of the process of establishing new macroalgal farms, the potential for gene flow between cultivated specimens and natural populations needs to be taken into consideration. Consequently, in the present study we have used a combined population genetic and hydrodynamic modelling approach to determine potential levels and patterns of gene flow in the kelp Saccharina latissima. Microsatellite analysis of 14 populations sampled across the northern part of the Irish Sea indicated four distinct genetic clusters. These were consistent with dispersal patterns indicated by the particle tracking model and show a combination of isolation by distance and genetic structuring due to local hydrodynamic conditions. At smaller scales (less than a few 10s of km), gene flow appears to be fairly extensive, with evidence of local population connectivity due to local currents. At larger scales, however, factors such as freshwater efflux and open water would appear to represent barriers to gene flow. Together, these patterns suggest that factors other than simple geographical distance and proximity need to be taken into account when planning the siting of kelp farms with the aim of minimizing gene flow to and from natural populations. PMID- 30293662 TI - Increased maternal Body Mass Index is associated with congenital heart defects: An updated meta-analysis of observational studies. AB - PURPOSE: To review and summarize the epidemiologic evidence on the association of maternal Body Mass Index (BMI) with risk of congenital heart defects (CHDs) and to assess the possible dose-response patterns. METHODS: Six electronic databases were searched for eligible studies up to April 2018. The summary risk estimates were calculated using either the fixed-effect models or random-effect models. A dose-response meta-analysis was also performed to capture the shape of the observed association. Subgroup and sensitivity analysis were conducted to explore the potential heterogeneity moderators. RESULTS: Twenty-nine studies involving 99,205 CHDs cases among 6,467,422 participants were included in the meta analysis. Mothers who were overweight (odds ratio [OR] = 1.07; 95% confidence intervals [CI]: 1.00-1.13) and obese (OR = 1.32; 95% CI: 1.21-1.43) had a significantly higher risk of total CHDs in their offspring when compared with those with normal weight. When obesity was further divided into class I (OR = 1.15; 95% CI: 1.11-1.20), class II (OR = 1.26; 95% CI: 1.18-1.34) and class III (OR = 1.42; 95% CI: 1.33-1.51) obesity, a significantly increased risk of total CHDs persisted. Different risks for specific CHD phenotypes were also found in different BMI categories. Furthermore, a nonlinear dose-response relationship between maternal BMI and risk of total CHDs was observed. Subgroup and sensitivity analyses identified the most relevant heterogeneity moderators. CONCLUSION: The increased maternal BMI is associated with the risk of developing CHDs in offspring. Severe obesity can play an independent role in the observed association, but the effect may be mediated by diabetes mellitus. Preventing obesity or excessive weight gain is a priority for CHDs prevention. PMID- 30293663 TI - Clinical impact of advanced chronic kidney disease on outcomes and in-hospital complications of Takotsubo Syndrome (broken-heart-syndrome): Propensity-matched national study. AB - Multiple studies evaluated the outcomes and complications rate of Takotsubo Syndrome (TTS) in patients with and without advanced chronic kidney disease (CKD), revealed conflicting results. This study aims to assess the clinical outcomes and impact of advanced CKD on patients hospitalized with Takotsubo Syndrome. Patients who presented with Takotsubo cardiomyopathy between 2010 and 2014 were identified in the National Inpatient Sample (NIS) database using the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM), and subsequently were divided into two groups, with advanced CKD and without advanced CKD. NIS is the largest all-payer inpatient stays database in the United States. The primary outcome was the effect of advanced CKD on inpatient mortality in comparison to the non-advanced CKD group. Secondary outcomes were the impact of CKD on TTS in-hospital complications. We also evaluated the length of hospital stay and the cost of hospitalization. Propensity score-matched analysis was performed to address potential confounding. The advanced CKD group had no significant increase in the risk of In-hospital mortality (OR 0.99; 95% CI 0.75-1.31, P = 0.269). However, advanced CKD patients were more likely to develop acute kidney injury (AKI) requiring dialysis (OR: 5.12, 95% CI: 3.16-8.30, P = <0.0001), and were more likely to stay longer at the hospital (OR 1.12; 95% CI 1.03 to 1.22, P 0.010). In conclusion, advanced chronic kidney disease does not increase immediate in-hospital mortality, neither most of the TTS in-hospital complications, apart from AKI and hospital length of stay, in comparison to the patients with non-advanced CKD. PMID- 30293664 TI - Late sodium channel blockade improves angina and myocardial perfusion in patients with severe coronary microvascular dysfunction: Women's Ischemia Syndrome Evaluation-Coronary Vascular Dysfunction ancillary study. AB - BACKGROUND: In a prior trial of late sodium channel inhibition (ranolazine) among symptomatic subjects without obstructive coronary artery disease (CAD) and limited myocardial perfusion reserve index (MPRI), we observed no improvement in angina or MPRI, overall. Here we describe the clinical characteristics and myocardial perfusion responses of a pre-defined subgroup who had coronary flow reserve (CFR) assessed invasively. METHODS: Symptomatic patients without obstructive CAD and limited MPRI in a randomized, double-blind, crossover trial of ranolazine vs. placebo were subjects of this prespecified substudy. Because we had previously observed that adverse outcomes and beneficial treatment responses occurred in those with lower CFR, patients were subgrouped by CFR <2.5 vs >=2.5. Symptoms were assessed using the Seattle Angina Questionnaire and the SAQ-7, and left-ventricular volume and MPRI were assessed by magnetic resonance imaging (MRI). Coronary angiograms, CFR, and MRI data were analyzed by core labs masked to treatment and patient characteristics. RESULTS: During qualifying coronary angiography, 81 patients (mean age 55 years, 98% women) had invasively determined CFR 2.69 +/- 0.65 (mean +/- SD; range 1.4-5.5); 43% (n = 35) had CFR <2.5. Demographic and symptomatic findings did not differ comparing CFR subgroups. Those with low CFR had improved angina (p = 0.04) and midventricular MPRI (p = 0.03) with ranolazine vs placebo. Among patients with low CFR, reduced left ventricular end-diastolic volume predicted a beneficial angina response. CONCLUSIONS: Symptomatic patients with CFR <2.5 and no obstructive CAD had improved angina and myocardial perfusion with ranolazine, supporting the hypothesis that the late sodium channel is important in management of coronary microvascular dysfunction. TRIAL REGISTRATION: clinicaltrials.gov Identifier NCT01342029. PMID- 30293665 TI - Impact of increasing dose of intracoronary adenosine on peak hyperemia duration during fractional flow reserve assessment. AB - BACKGROUND: Fractional Flow Reserve (FFR) is currently indicated as a first line strategy for the functional assessment of intermediate coronary stenoses. However, the protocol for inducing hyperemia still lacks standardization. Intracoronary adenosine boli, with a progressive increase to high-dosage, have been proposed as a sensitive and accurate strategy for the classification of coronary stenoses, although being potentially affected by the achievement of plateau of the effect and by a less prolonged and stable hyperemia as compared to intravenous administration. Therefore, the aim of the present study was to define the conditioning parameters and assess the impact of increasing-dose intracoronary adenosine on peak hyperemia duration in patients undergoing FFR for intermediate coronary stenoses. METHODS: FFR was assessed in patients with intermediate (40 to 70%) lesions by pressure-recording guidewire (Prime Wire, Volcano), after induction of hyperemia with intracoronary boli of adenosine (from 60 to 1440 MUg, with dose doubling at each step). Hyperemic duration was defined as the time for the variation form minimum FFR +/- 0.02 and time to recovery till baseline values. RESULTS: We included 87 patients, undergoing FFR evaluation of 101 lesions. Mean peak hyperemia duration and time to recovery significantly increased with adenosine doses escalation (p = 0.02 and p < 0.001). Peak hyperemia duration and time to recovery with 1440 MUg adenosine were 14.5 +/- 12.6 s and 45.2 +/- 30.7 s, respectively. Hyperemia duration was not related to Quantitative Coronary Angiography (QCA) parameters or FFR values. In fact, a similar increase in the time of hyperemic peak was noted when comparing patients with positive or negative FFR (pbetween = 0.87) or patients with lesions < or >=20 mm (pbetween = 0.92) and lesions involving left main coronary or proximal left anterior descending artery (LAD) (pbetween = 0.07). A linear relationship was observed between time to recovery and FFR variations, with a greater time to baseline required in patients with FFR <= 0.80 (p = 0.003) and in lesions >= 20 mm (p = 0.006), but not in LAD/LM lesions (p = 0.55). CONCLUSIONS: The present study shows a progressive raise in the duration of peak hyperemia and time to recovery, after the administration of increasing doses of intracoronary adenosine for the assessment of FFR. Therefore, considering the potential advantages of a high-dose adenosine protocol, allowing a more prolonged hyperemia and a more precise and reliable measurement of FFR, further larger studies with such FFR strategy should certainly be advocated to confirm its safety and benefits, before its routinely use recommendation. PMID- 30293666 TI - Impact of angiographic coronary artery disease complexity on ischemic and bleeding risks and on the comparative effectiveness of zotarolimus-eluting vs. bare-metal stents in uncertain drug-eluting stent candidates. AB - BACKGROUND: The impact of coronary artery disease (CAD) extension/complexity on outcomes and on the comparative benefits/risks of zotarolimus-eluting stent (ZES) versus bare-metal stents (BMS) remains unclear in patients at high risk of bleeding or thrombosis or at low restenosis risk. METHODS: We performed a post hoc analysis of the ZEUS trial. The impact of coronary anatomic complexity measured by the SYNTAX score on the differences in outcomes following ZES and BMS was assessed at 1 year. RESULTS: The mean SYNTAX score was 16.3 +/- 13.1 with a median of 12 (IQR: 7 to 22). We stratified patients according to SYNTAX tertiles (0-8: n = 563; >8-19 n = 532; >19: n = 511), and observed that the higher the score, the correspondingly higher was the rate of the primary endpoint of major adverse cardiovascular events (MACE) and other ischemic events, but not bleeding after adjustment. The superior efficacy of ZES versus BMS for MACE was consistent across SYNTAX tertiles (tertile 1: HR 0.71, 95% CI 0.44-1.13; tertile 2: HR 0.71, 95% CI 0.46-1.09; tertile 3: HR 0.83, 95% CI 0.61-1.10) without significant heterogeneity (p for trend = 0.55). This between-groups difference mainly reflected a reduction in MI and TVR without effect on mortality. There was no significant interaction between the SYNTAX score and allocated stent type with respect to ischemic and bleeding endpoints. CONCLUSIONS: The SYNTAX score was predictor of major adverse cardiovascular events but not bleeding and ZES provided superior efficacy and safety than BMS across the whole spectrum of CAD complexity. SYNTAX score may be routinely used for the assessment of the ischemic risk (but not bleeding) after PCI and should not guide the decision-making for DES versus BMS in patients undergoing PCI. PMID- 30293667 TI - ECG left ventricular hypertrophy as a risk predictor of sudden cardiac death. AB - BACKGROUND: Electrocardiographic (ECG) left ventricular hypertrophy (LVH) is an established risk factor for cardiovascular events. However, limited data is available on the prognostic values of different ECG LVH criteria specifically to sudden cardiac death (SCD). Our goal was to assess relationships of different ECG LVH criteria to SCD. METHODS: Three traditional and clinically useful (Sokolow Lyon, Cornell, RaVL) and a recently proposed (Peguero-Lo Presti) ECG LVH voltage criteria were measured in 5730 subjects in the Health 2000 Survey, a national general population cohort study. Relationships between LVH criteria, as well as their selected composites, to SCD were analyzed with Cox regression models. In addition, population-attributable fractions for LVH criteria were calculated. RESULTS: After a mean follow-up of 12.5 +/- 2.2 years, 134 SCDs had occurred. When used as continuous variables, all LVH criteria except for RaVL were associated with SCD in multivariable analyses. When single LVH criteria were used as dichotomous variables, only Cornell was significant after adjustments. The dichotomous composite of Sokolow-Lyon and Cornell was also significant after adjustments (hazard ratio for SCD 1.82, 95% confidence interval 1.20-2.70, P = 0.006) and was the only LVH measure that showed statistically significant population-attributable fraction (11.0%, 95% confidence interval 1.9-19.2%, P = 0.019). CONCLUSIONS: Sokolow-Lyon, Cornell, and Peguero-Lo Presti ECG, but not RaVL voltage, are associated with SCD risk as continuous ECG voltage LVH variables. When SCD risk assessment/adjustment is performed using a dichotomous ECG LVH measure, composite of Sokolow-Lyon and Cornell voltages is the preferred option. PMID- 30293668 TI - The asymmetry of dermatoglyphic finger ridge counts and the geographic altitude of the Jujenean population in northwest Argentina. AB - Asymmetry is omnipresent in the living world and therefore is a measure of developmental noise and instability. The main stressing agent in high-altitude ecosystems is hypobaric hypoxia. The variation in bilateral dermatoglyphic symmetry in populations from the Province of Jujuy in northwest Argentina is analyzed, and these results are compared to those for other populations with different ethnic and environmental backgrounds. Fingerprints were collected from 310 healthy students (140 males and 170 females) aged 18-20 years from three localities in Jujuy Province-Abra Pampa (3484 m above sea level), Humahuaca (2939 m above sea level), and San Salvador de Jujuy (1260 m above sea level). Asymmetry by sex was assessed based on radial and ulnar ridge counts to determine its pattern of variability (directional asymmetry [DA], fluctuating asymmetry [FA] and antisymmetry), and asymmetry and diversity indices were calculated. A bivariate plot and principal component analysis (PCA) were used to compare these indices with those for other populations. Homogeneity was found between populations and sexes when radial and ulnar ridges were counted. FA values did not show significant differences by locality or side (ulnar and radial), but significant differences were found by finger and sex, with males showing significantly greater FA values. The asymmetry and diversity indices clearly group the Andean populations and separate them from populations of different ethnic and geographic origin. Only the diversity index showed significant differences by locality in males, which suggests a substantially different genetic component in Abra Pampa male samples. PMID- 30293669 TI - Psychosocial Health and Lifestyle Behaviors in Young Adults Receiving Renal Replacement Therapy Compared to the General Population: Findings From the SPEAK Study. AB - RATIONALE & OBJECTIVE: Patients in late adolescence and early adulthood receiving renal replacement therapy (RRT) face disruption to normal activities, which affects well-being. We aimed to define psychosocial and lifestyle outcomes for young adults on RRT compared to the general population. STUDY DESIGN: We undertook a cross-sectional survey (the SPEAK [Surveying Patients Experiencing Young Adult Kidney Failure] Study) using validated measures and general population comparator data from the Health Survey for England and Avon Longitudinal Study of Parents and Children. Additional clinical information was obtained from the UK Renal Registry. SETTING & PARTICIPANTS: 16- to 30-year-olds receiving RRT. OUTCOMES: Psychosocial health and lifestyle behaviors. ANALYTICAL APPROACH: We compared outcomes between populations using age- and sex-adjusted regression models, weighted to account for response bias by sex, ethnicity, and socioeconomic status. Our findings were used to update recent meta-analyses. RESULTS: We recruited 976 young adults and 64% responded to the survey: 417 (71%) with kidney transplants and 173 (29%) on dialysis therapy. Compared to the general population, young adults on RRT were less likely to be in a relationship and have children and more likely to live in the family home, receive no income, and be unable to work due to health. They had poorer quality of life, worse well being, and twice the likelihood of a psychological disturbance (OR, 2.7; 95% CI, 2.0-3.7; P<0.001). They reported less smoking, alcohol and drug abuse, and crime. In a meta-analysis, our study showed the greatest differences in quality of life compared to the general population. LIMITATIONS: Cross-sectional study design, meaning that we could not track the impact of treatment changes on the outcomes. CONCLUSIONS: This study involving a large cohort of young adult transplant recipients and dialysis patients provides evidence of worse psychosocial outcomes but more positive lifestyle behaviors in young adults on RRT compared to the age matched general population.

PMID- 30293672 TI - Transcriptome analysis of the midgut gland of the brown shrimp Crangon crangon indicates high polymorphism in digestive enzymes. AB - Tolerance of organisms towards heterogeneous and variable environments is highly related to physiological flexibility. An effective strategy to enhance physiological flexibility is the expression of polymorphic enzymes. This seems to be the case in the brown shrimp Crangon crangon. It shows high reproduction rates, feeds opportunistically on endo- and epibenthic organisms, and is apparently well adapted to variable environmental conditions. Previous electrophoretic studies revealed a high level of polymorphism and no consistent phenotype of digestive enzymes between individuals. In order to understand the underlying biochemical processes, we carried out a transcriptome-based study of digestive enzymes of C. crangon. Detailed sequence analyses of triacylglycerol lipase, phospholipase A2, alpha amylase, chitinase, trypsin and cathepsin L were performed to identify putative isoforms. The number of isoforms, and thus the degree of polymorphism varied among enzymes: lipases and carbohydrases showed higher numbers of isoforms in enzymes that besides their extracellular function also have diverse intracellular functions. Furthermore, cysteine proteinases showed a lower polymorphism than serine proteinases. We suggest that the expression of enzyme isoforms improves the efficiency of C. crangon in gaining energy from different food sources. PMID- 30293673 TI - Transcriptomic and metabolic response to chronic and acute thermal exposure of juvenile geoduck clams Panopea globosa. AB - The Cortes geoduck Panopea globosa is a large bivalve with a high commercial value distributed from the southern Pacific coast of the Baja California Peninsula to the northern Gulf of California, inhabiting a wide range of subtropical temperatures. A new record of this species in shallower waters suggests that it can tolerate a warmer environment than previously thought. To better understand the whole-body and molecular response mechanisms to different temperatures, we assessed the metabolic rate of juvenile individuals exposed to chronic and acute thermal conditions and analyzed the transcriptomic response in ctenidial tissues. Whole-body metabolic rate measurements showed that juveniles were able to acclimate at least partially within three weeks from 20 degrees C (C20) to 29 degrees C (C29), while organisms acutely exposed to 29 degrees C (A29) significantly increased their metabolic rate. This was coincident with transcriptomic results, as similar gene expression patterns were found in clams chronically exposed to C29 and C20, but different from those acutely exposed to 29 degrees C (A29) and 31 degrees C (A31). High degree of expression of genes involved in DNA repair and transcription regulation were found in C29 juveniles, whereas protective genes against oxidative stress were highly expressed in A29 organisms. A high expression of genes involved in protein re-folding was also observed in A31 juveniles. In conclusion, the combined results of whole-body metabolism and transcriptomic expression patterns suggest that P. globosa juveniles have a high physiological plasticity and are well adapted to inhabit an environment with broad temperature fluctuations. PMID- 30293674 TI - Triple therapy: A review of antithrombotic treatment for patients with atrial fibrillation undergoing percutaneous coronary intervention. AB - In patients with atrial fibrillation (AF), concomitant coronary artery disease is often present, and vice versa. Optimal antithrombotic treatment for patients with AF undergoing percutaneous coronary intervention (PCI) is one of the major concerns in the field of cardiology. Triple therapy, a combination of oral anticoagulant (OAC) plus dual antiplatelet therapy with aspirin and P2Y12 inhibitor, has been used for patients with AF undergoing PCI in recent decades to reduce ischemic events under guideline recommendations. However, triple therapy is well-known to induce severe bleeding events. Recently, the results of several clinical trials have been published, and the latest guidelines recommend that most patients should undergo dual therapy (i.e. OAC plus P2Y12 inhibitor) from the beginning of PCI, or triple therapy only peri-PCI period and immediately shift to dual therapy after hospital discharge. Although these recommendations are useful and appear to be reasonable, no studies have validated this. In addition, there are a number of unresolved issues regarding the antithrombotic treatment for patients with AF undergoing PCI such as risk prediction models and the best combination of OAC with antiplatelet agents, and prospective trials are ongoing. This review article will summarize current evidence and focus on the optimal regimen of antithrombotic treatment for patients with AF undergoing PCI.

AB - BACKGROUND: Recent studies have shown an increase in the prevalence of silicosis due to the use of artificial quartz aggregates (AQA). The aim of this study was to assess the cases of silicosis in our area reported to the Healthcare Information System for Occupational Epidemiological Surveillance of the Autonomous Community of Valencia to detect new agents of exposure to silica and working conditions that promote its onset. MATERIAL AND METHOD: A descriptive study was conducted of cases of silicosis reported to the Healthcare Information System for Occupational Epidemiological Surveillance of the Autonomous Community of Valencia from January 2009 to September 2016. The data sources include epidemiological-occupational surveys and medical reports. RESULTS: Nineteen cases of silicosis were reported, 74% of which were diagnosed using high-resolution computed tomography. Some 68.4% of the cases were related to the handling of AQA, as assemblers/cutters/sanders of countertops. The subgroup's mean age was 46.62+/ 13.33 years, and the mean exposure was 11.00+/-3.58 years. The rest of the patients worked in companies with no AQA exposure, with a mean age of 62.33+/ 16.22 years and a mean exposure of 27.16+/-8.44 years (P<.05). Four cases presented complicated forms (3 exposed to AQA). CONCLUSIONS: The work of assembling/cutting/sanding AQA countertops presents a high risk of developing the disease. The mean age at onset and the exposure time for this group is lower, and the percentage of complicated clinical forms is higher. Improvements need to be made in preventive planning for companies with exposure to these new agents.

AB - Fixed DC was compared to ceftriaxone, ceftriaxone with 200 MUA fixed DC, or no treatment in a rat model of methicillin-susceptible Staphylococcus aureus foreign body osteomyelitis. After 3 weeks, fewer bacteria were present in bones of the ceftriaxone group (5.71 log10cfu/g [P = 0.0004]) and the ceftriaxone/DC group (3.53 log10cfu/g [P = 0.0002]) than untreated controls (6.70 log10cfu/g). Fewer bacteria were present in the ceftriaxone/DC group than in the ceftriaxone-alone and DC-alone groups (P = 0.0012 and 0.0008, respectively). There were also fewer bacteria on the implanted wires in the groups treated with ceftriaxone (5.47 log10cfu/cm2) or ceftriaxone/DC (2.82 log10cfu/cm2) than in the untreated controls (6.44 log10cfu/cm2 [P = 0.0003 and 0.0002, respectively]). There were fewer bacteria in the ceftriaxone/DC rats than in the ceftriaxone-alone- and fixed DC-alone-treated rats (P = 0.0017 and 0.0016, respectively). Fixed DC with an antibiotic may be useful for treating foreign-body infections caused by S. aureus. PMID- 30293678 TI - Relevance or performance: potential savings associated with verification of prior results before performing microbiology analysis. AB - OBJECTIVE: In an era of rising healthcare expenditures, it is critical to find ways to decrease cost. The objective of this study is to evaluate the number of repeated tests and the associated cost savings in a university-affiliated hospital. METHODS: The following 7 microbiology analysis were assessed for nonrepeat testing: HCV antibody, HBV core antibody, CMV IgG, rubella IgG, Treponema pallidum antibodies, Clostridioides difficile toxin detection, and vancomycin-resistant enterococci PCR. Presence of a prior positive result leads to the cancellation of subsequent orders. RESULTS: Percentages of not repeated test ranged from 0.1% to 21.4%. Rubella IgG had the highest proportion of unnecessary repeat testing. Total cost savings were estimated at $33,627 for 2016. CONCLUSION: Unnecessary repeated microbiologic test can account for a non negligible part of total volume test. Use of an automated software to detect unnecessary repeated microbiologic test through laboratory information system can generate important savings. PMID- 30293679 TI - Numerical and analytical investigation of the possibilities to enhance the thermal conductivity of core-shell particle packed beds. AB - We report on a numerical study of the thermal conductivity of core-shell particle packed bed columns. Covering a variety of packing structures and a broad range of mobile phase and porous zone conductivities, it was in all cases found that switching to particles with a highly conducting core (e.g., with a gold or copper core instead of a silica core) would produce a much smaller increase of the effective heat conductivity of the bed (keff) than previously expected in literature. We found maximal increases on the order of some 20-70%, which is much lower than the potential increases up to 2000% assumed in literature. The overestimation in literature could be attributed to the fact that this literature was based on an incorrect extrapolation of the Zarichnyak-model which was the heat conductivity model predominantly used up till now. On the other hand, the computed relationships between keff and the core conductivity obtained in the present study are in good agreement with an analytical solution derived from the effective medium theory, a theory which is physically much more relevant for the case at hand than the Zarichnyak-model. The results also show that the observed increase in effective bed conductivity between fully porous and core-shell particle beds frequently observed in literature is not only due to the presence of the core, but that differences in the shell layer conductivity can play an equally important role. In addition, it could also be demonstrated that, if ways could be found to increase the conductivity of the shell layer, this would produce a much stronger increase of the overall bed conductivity than will ever be possible by increasing the conductivity of the cores. PMID- 30293680 TI - Co3O4 nanoparticles at sublethal concentrations inhibit cell growth by impairing mitochondrial function. AB - Co3O4 nanoparticles (NPs) are one kind of the important nanomaterials that have the application potential in catalyst, electrochromic devices, sensors, etc. However, their biological effect remains to be detailed. In this study, we investigated the effect of the as-synthesized Co3O4 NPs (15-30 nm) on the growth of mammalian cells, and found that the NPs severely inhibited cell growth at the sublethal concentrations from 12.5 to 200 mg/L. Interestingly, the NPs did not cause obvious cell death and ROS accumulation, indicating that their inhibitory effect was not attributed to both apoptosis- or necrosis-related cell death and ROS accumulation. Transcription profiling analysis revealed that the NPs caused remarkable down regulation of the genes involved in mitochondrial functions. Transmission electron microscopy (TEM) and biochemical analysis further showed that the NPs might interact with the mitochondria, impairing the mitochondrial membrane potential (MMP) and ATP production. This study uncovers a mitochondrial respiratory chain-related and ROS-independent toxicity mechanism of Co3O4 NPs in eukaryotic cells. PMID- 30293681 TI - Crystal structure of an ENT domain from Trypanosoma brucei. AB - Trypanosoma brucei (T. brucei) is a parasitic protozoan causing human sleeping sickness and related animal diseases. ENT (EMSY N-terminal) domain was first found in EMSY protein which has been proved to be involved in multiple biological processes such as DNA repair, tumorigenesis, and transcriptional regulation. So far, little is known about the function and structure of ENT domains from protozoan. Q385P5 from T. brucei, containing an ENT domain at its N-terminus, is a conserved protein in related kinetoplastid parasites. In this work, the crystal structure of ENT domain of Q385P5 (TbENT) was solved at a resolution of 2.3 A. TbENT adopts a club-like shape consisting of five helixes, which is similar to the structure of human EMSY ENT domain (HsENT). Interestingly, TbENT shows significantly different orientation on the fifth alpha-helix compared with HsENT. Meanwhile, human HP1 interacts with a conserved motif adjacent to EMSY ENT domain. However, this conserved binding motif is absent in Q385P5. These differences may imply the different protein interactions and roles of Q385P5 and its ENT domain in T. brucei. PMID- 30293682 TI - Three-dimensional model of intracellular and intercellular Ca2+ waves propagation in endothelial cells. AB - Intracellular and intercellular Ca2+ waves play key roles in cellular functions, and focal stimulation triggers Ca2+ wave propagation from stimulation points to neighboring cells, involving localized metabolism reactions and specific diffusion processes. Among these, inositol 1,4,5-trisphosphate (IP3) is produced at membranes and diffuses into the cytoplasm to release Ca2+ from endoplasmic reticulum (ER). In this study, we developed a three-dimensional (3D) simulation model for intercellular and intracellular Ca2+ waves in endothelial cells (ECs). 3D model of 2 cells was reconstructed from confocal microscopic images and was connected via gap junctions. Cells have membrane and cytoplasm domains, and metabolic reactions were divided into each domain. Finally, the intracellular and intercellular Ca2+ wave propagations were induced using microscopic stimulation and were compared between numerical simulations and experiments. The experiments showed that initial sharp increases in intracellular Ca2+ occurred approximately 0.3 s after application of stimuli. In addition, Ca2+ wave speeds remained constant in cells, with intracellular and intercellular speeds of approximately 35 and 15 MUm/s, respectively. Simulations indicated initial increases in Ca2+ concentrations at points of stimulation, and these were then propagated across stimulated and neighboring cells. In particular, initial rapid increases in intracellular Ca2+ were delayed and subsequent intracellular and intercellular Ca2+ wave speeds were approximately 25 and 12 MUm/s, respectively. Simulation results were in agreement with those from cell culture experiments, indicating the utility of our 3D model for investigations of intracellular and intercellular messaging in ECs.

AB - Malignant melanoma is one of the most fatal and aggressive skin cancers, originating from pigment-containing melanocytes. Despite progress in clinical research, treatment options for malignant melanoma have been limited. The nuclear factor of activated T-cell 5 (NFAT5), originally identified as tonicity regulated transcription factor Ton/EBP, is now known as a carcinogenic gene in several types of cancer pathology. In this study, we knocked down NFAT5 to investigate its role in melanoma cancer. shRNA-mediated knockdown of NFAT5 led to a significant decrease in cell proliferation in vitro. Additionally, depletion of NFAT5 inhibited the cell migratory ability of B16BL6 melanoma cells and led to more accumulation at the G2/M phase of the cell cycle. Furthermore, NFAT5 was essential for the development of melanoma cancer pathophysiology in an in vivo mouse model. NFAT5 knockdown-induced tumor growth was slow and tumor volume was significantly reduced compared to mock controls. Moreover, NFAT5 knockdown was associated with a low number of metastatic nodules on the lung and liver. To our knowledge, our data demonstrate for the first time a role of NFAT5 in the development of melanoma. We provide evidence for NFAT5 as a marker of cell migration and metastasis, indicating that NFAT5 represents a novel therapeutic target in melanoma.

AB - Development of an effective and safe anti-cancer drug is an urgent request for hepatocellular carcinoma (HCC). In this study, we synthesized a series of novel indole substituted dihydropyrido[2,3-d]pyrimidines through the multicomponent reactions to connect pyrido[2,3-d]pyrimidine and indole moities via an one-pot three-component reaction of 3-cyanoacetyl indoles 1, various aromatic aldehyde 2, and 2,6-diaminopyrimidin-4(3H)-one 3. Subsequently, we screened their cytotoxicity via CCK-8 assay in HepG2 cells, a human hepatoma cell line and chose compound 4p that showed the lowest dosage of IC50 to study the antitumor activities to HCC. Interestingly, 4p significantly induced the cell cycle arrest and apoptosis of HepG2 via targeting AKT and ERK1/2 signaling pathways in vitro. To improve the solubility of compound 4p, we hosted this compound into the substituted glucopyranose ring of (2-Hydroxypropyl)-beta-cyclodextrin (HBC), a cosolvent approved by FDA with the help of ultrasonication and heating. Finally, we showed that oral administration of HBC-hosted 4p effectively inhibited tumor growth and prolonged the survival time of tumor-bearing mice in subcutaneously xenografted model. These results suggest that multicomponent reactions connecting pyrido[2,3-d]pyrimidine and indole moities is a productive and economical method for the synthesis of anticancer compound, and oral administration of HBC-hosted 4p is an effective and safe agents for treatment of HCC, whose clinical application potency warrant further studies. PMID- 30293686 TI - Intrusive memories of trauma: A target for research bridging cognitive science and its clinical application. AB - Intrusive memories of a traumatic event can be distressing and disruptive, and comprise a core clinical feature of post-traumatic stress disorder (PTSD). Intrusive memories involve mental imagery-based impressions that intrude into mind involuntarily, and are emotional. Here we consider how recent advances in cognitive science have fueled our understanding of the development and possible treatment of intrusive memories of trauma. We conducted a systematic literature search in PubMed, selecting articles published from 2008 to 2018 that used the terms "trauma" AND ("intrusive memories" OR "involuntary memories") in their abstract or title. First, we discuss studies that investigated internal (neural, hormonal, psychophysiological, and cognitive) processes that contribute to intrusive memory development. Second, we discuss studies that targeted these processes using behavioural/pharmacological interventions to reduce intrusive memories. Third, we consider possible clinical implications of this work and highlight some emerging research avenues for treatment and prevention, supplemented by new data to examine some unanswered questions. In conclusion, we raise the possibility that intrusive memories comprise an alternative, possibly more focused, target in translational research endeavours, rather than only targeting overall symptoms of disorders such as PTSD. If so, relatively simple approaches could help to address the need for easy-to-deliver, widely-scalable trauma interventions. PMID- 30293687 TI - Retrospective study of the incidence of portal vein thrombosis after splenectomy in hematological disorders: Risk factors and clinical presentation. AB - OBJECTIVE: Portal vein thrombosis (PVT) has been described as a rare complication after splenectomy. PVT associated risk factors after splenectomy in hematological disorders are poorly recognized. The aim of this study was to assess the prevalence and risk factors of PVT incidence in splenectomized patients. METHODS: One hundred twelve splenectomized patients with various hematologic diseases between 2008 and 2018 were enrolled in this study. Diagnosis was confirmed by Doppler ultrasonography (DUSG) and risk factors for PVT were sought based on the comparison of clinical and laboratory features between patients without and with PVT. RESULT: PVT was diagnosed in 4 (3.57%) patients in spite of receiving antiplatelet therapy. Patients with PVT were beta-thalassemia major (n = 2) and beta-thalassemia intermedia (n = 2). beta-thalassemia patients had a 3.5 times higher odds for PVT (95% CI: 2.41-5.33). No significant differences between patients with and without PVT in terms of age, gender and laboratory features were found. CONCLUSION: According to our data, beta-thalassemia, especially intermediate form, may be a risk factor for PVT and it can occur in spite of receiving antiplatelet therapy. Given that beta-thalassemia patients are at risk, early PVT detection may be useful for reduction of fatal PVT complication in splenectomized patients. PMID- 30293688 TI - Objects build orientation, positioning, and curing influence dimensional accuracy and flexural properties of stereolithographically printed resin. AB - OBJECTIVE: To evaluate the influence of printing parameters on flexural properties and accuracy of SLA-printed standard objects. METHODS: Thirty specimens were printed in 0 degrees , 45 degrees and 90 degrees orientation. Fourth nine more specimens were printed evenly on the build platform. forty more specimens were printed and polymerized with three curing unit. Length, height and width was measured three times for each specimen and compared to the original dimensions. Afterwards all specimens underwent a three-point-bending test to assess their flexural properties. One way ANOVA and the Post-Hoc all pairs Tukey Kramer HSD test were used for data evaluation. RESULTS: The print orientation influences the printing accuracy. The parameters printed along the Z-axis are particularly prone to inaccuracies. Specimens with 45 degrees orientation were found to be the most accurate. Object printed on the borders of build platform a rather prone to inaccuracies than those in the center. The 90 degrees specimens with layer orientation parallel to the axial load showed the superior flexural strength and flexural modulus. The use of different curing unit is unlikely to affect the objects printing accuracy and flexural properties. SIGNIFICANCE: The anisotropical behavior of printed specimens with regards to build orientation and positioning was revealed. The understanding of how the adjustable printing parameter influence the printing outcome is important for a precise fabrication of surgical guides. Inaccuracies up to 10% along the Z-axis, as revealed in the present study,may restrict an accurate implant placement. PMID- 30293689 TI - Do collagen cross-linkers improve dentin's bonding receptiveness? AB - OBJECTIVES: Dentin biomodification using collagen cross-linkers has been proposed as one of the strategies to improve bond durability of adhesives to dentin. However, literature is not very consistent regarding their benefit, in particular when cross-linkers are applied in clinically realistic application times. This study investigated the effect of three cross-linkers on the mini-interfacial fracture toughness (mini-iFT) of four adhesives bonded to dentin following either etch&rinse (E&R) or self-etch (SE) modes. METHODS: 60 molars were randomly divided in accordance with the three variables: cross-linker, adhesive and bonding mode (n=5). The cross-linkers glutaraldehyde (5wt%; GA), proanthocyanidin (6.5wt%; PA), or UVA-activated riboflavin (0.5wt%; RB), and distilled water (control) were applied on dentin for 60s after acid-etching (E&R) or before self etching (SE). The 3-step E&R adhesive (3E&Ra) OptiBond FL (Kerr), the 2-step SE adhesive (2SEa) Clearfil SE Bond 2 (Kuraray Noritake) and the universal adhesives G-Premio Bond (GC) and Prime&Bond Active (Dentsply), the latter two employed in both E&R and SE modes, were applied following the respective manufacturer's instructions. Composite buildups (8*8*8mm) were made using Filtek Supreme XTE (3M) prior to 1-week storage in artificial saliva. After the teeth were sectioned into mini-specimens (1.5*2.0*18mm), a single notch was prepared at the adhesive dentin interface. Half of the specimens were immediately loaded until failure by 4-point bending to determine the mini-iFT, while the remaining specimen set was tested upon 6-month aging. Data were statistically analyzed with a linear model (p<0.05). RESULTS: No significant decrease in mini-iFT was noted only for PA (p<0.05), while the mini-iFT decreased for both other cross-linkers and in quite a similar way as when solely water (Wa) was applied. SIGNIFICANCE: The cross linker proanthocyanidin (PA) applied in clinically relevant conditions was able to maintain a stable mini-iFT after 6-month aging. The incorporation of UVA activated riboflavin (RB) and glutaraldehyde (GA) in the dentin-bonding protocol appeared not effective to improve the stability of adhesive-dentin interfaces. PMID- 30293690 TI - The effect of the conductivity of a film located near a piezoelectric resonator with a lateral electric field based on the PZT ceramics on its characteristics. AB - In this paper, we investigated theoretically and experimentally the effect of the conductivity of the film located in the immediate vicinity of the free side of a piezoelectric resonator based on the PZT ceramics on its characteristics. It is shown that with increasing the conductivity of the film at first the parallel resonant frequency does not change, then it decreases in a certain interval and after that remains practically constant. With increasing the width of the gap between the film and the resonator, the resonant frequency increases and reaches the saturation. At that the degree of the total frequency change decreases with decreasing the conductivity of the film. We also investigated the dependence of the maximum value of the real part of the electrical impedance on the film conductivity at the different values of the width of the gap between the film and the resonator. The dependences of the maximum value of the real part of the electrical impedance on the width of the gap between the film and the resonator are also obtained for different values of the film conductivity. A comparison of the theoretical and experimental data showed their good qualitative agreement. PMID- 30293691 TI - Signal noise based transfer function approach for reliability estimation of ultrasonic inspection. AB - In recent years several methods for reducing the burden of experimentation for obtaining Probability of Detection (PoD) curves have been proposed, especially involving the use of numerical simulation. In particular, there is much interest in being able to estimate the PoD capabilities of a given NDE method, target embodiment and material, provided this is known for some canonical material for the same combination of method/embodiment. Ultrasonic experiments on materials with low signal to noise ratio (SNR) are often difficult and time consuming since the higher signal noise causes serious complications. Set in this context, this paper proposes an approach for transferring PoD curves among materials with different SNR values. The classical transfer function PoD approach is based on the hypothesis that the ratio of signals in related quadrants is equal, which requires large datasets for multiple quadrants. The approach proposed here directly deals with SNR instead of the ratio of signals, and thus requires only the experimental data of the parent application. The new approach is illustrated through example cases involving the prediction of PoD curves for ultrasonic inspection of an aluminium plate using the empirical PoD data for the same in austenitic stainless steel and mild steel. The approach is also demonstrated in each of the possible combinations among these three materials. PMID- 30293692 TI - Phantom limb sensations in the ear of a patient with a brachial plexus lesion. AB - Referred phantom sensations are frequently reported following a peripheral injury. However, very few cases describe such sensations of the ear, and it remains unclear how the aural nerve territory can be remapped to one specific peripheral nerve region. We report on a patient with brachial plexus avulsion who underwent sensory testing and was asked to report the location of the stimulated site and any other sensations experienced. The patient spontaneously described the sensation of his arm being separate from his body. Despite visual input, he felt that his fist was closed, with his thumb pointing inward. Importantly, he felt clear and reproducible sensations from the affected arm when the ipsilateral ear was touched. These referred sensations were noted just 15 days after sustaining the injury. The arm nerve territory was systematically remapped to a specific aural nerve territory by applying both manual and electrical stimulation. Stimulation of the external ear, which is innervated by the vagus nerve, showed high spatial specificity for the dorsal and volar skin surfaces of the limb, and clearly delineated digits. Somatosensory-evoked potentials indicated that cortical adaptation in the somatosensory stream transferred a spatially organized map of the limb to the skin of the outer ear. This referral of sensations to the ear, as distinct from the face, provides evidence of highly specific topographical reorganization of the central nervous system following peripheral injury. Rapid map changes in the phantom sensation to the ear as a function of stimulation of vagus nerve suggest that the reorganization process can occur in cortex rather than in the brainstem. PMID- 30293693 TI - Compensatory Cognitive Training for psychosis: Effects on negative symptom subdomains. AB - Research identifying the effects of cognitive training on negative symptoms of psychosis is limited. We examined the effects of Compensatory Cognitive Training (CCT) on expressive deficits and social amotivation in a randomized controlled trial comparing CCT to standard pharmacotherapy alone in 43 individuals with psychosis. ANCOVA analyses demonstrated significant CCT-associated effects on both expressive deficits and social amotivation. Moreover, improvements in both sub-domains were associated with improvements in global life satisfaction, with improvements in social amotivation also related to increased social contact. CCT appears to be a beneficial treatment approach for improving multiple aspects of negative symptoms. PMID- 30293695 TI - Searle on the biology of seeing. AB - Searle offers an account of seeing as a conscious state not constituted by the object(s) seen. I focus in this article on his biological case for this thesis, and argue that the biological considerations he adduces neither establish his own position nor defeat a rival object-inclusive view. I show (among other things) that taking seeing to be a biological state is compatible with its being (partially) constituted by the object(s) seen. PMID- 30293696 TI - Metformin Ameliorates Periapical Lesions through Suppression of Hypoxia-induced Apoptosis of Osteoblasts. AB - INTRODUCTION: Intramuscular injection of metformin has been shown to inhibit the progression of periapical lesions in rats by decreasing the number of receptor activator of nuclear factor-kappabeta ligand- and tartrate-resistant acid phosphatase-positive cells. In this study, we investigated the effect of metformin on hypoxia-induced apoptosis of osteoblasts and the therapeutic activity of intracanal metformin in induced periapical lesions in rats. METHODS: The influence of metformin on hypoxia-induced mitochondrial superoxide production in human osteoblasts was examined by using MitoSOX (Invitrogen, Carlsbad, CA) fluorescence dye signaling. The release of cytochrome c from mitochondria and the cleavage of procaspase-9 and poly(adenosine diphosphate-ribose) polymerase were evaluated by Western blot analysis. Apoptotic cell fraction was assessed by DNA content flow cytometry. In a rat model of induced periapical lesions, the effect of intracanal metformin on disease progression was appraised by 2-dimensional radiography and micro-computed tomographic imaging. Oxidative lesions and apoptotic activity of osteoblasts in vivo were estimated, respectively, by 8 hydroxy-2'-deoxyguanosine staining and terminal deoxynucleotidyl transferase dUTP nick end labeling. RESULTS: Metformin inhibited hypoxia-enhanced mitochondrial superoxide production in osteoblasts. Metformin suppressed hypoxia-induced cytochrome c release from mitochondria and the cleavage of procaspase-9 and poly(adenosine diphosphate-ribose) polymerase. Metformin repressed hypoxia augmented apoptotic cell fraction. In a rat model, intracanal metformin diminished the size of periapical lesions and the oxidative damage and apoptotic activity in osteoblasts. CONCLUSIONS: Hypoxia increased oxidative stress in osteoblasts and enhanced cell death through activation of the mitochondrial pathway of apoptosis. Metformin attenuated the oxidative and cytotoxic action of hypoxia. The therapeutic effect of metformin on periapical lesions is partially caused by its antioxidative activity. PMID- 30293697 TI - New developments in liquid-liquid extraction, surface modification and agglomerate-free processing of inorganic particles. AB - This review describes new methods for the particle extraction through liquid liquid interface (PELLI). The discovery of new surface modification techniques, advanced extractors and new adsorption mechanisms enabled novel applications of PELLI in nanotechnology of metals, quantum dots, oxides and hydroxides. Colloidal and interface chemistry of PELLI is emerging as a new area of technological and scientific interest. The progress achieved in the understanding of particle behavior and interactions at the liquid-liquid interface, phase transfer and interface reactions allowed for the development of new extraction mechanisms. An important breakthrough was the development of surface modification techniques for extraction of functional oxides. Especially important is the possibility of particle transfer from the synthesis medium to the device processing medium, which facilitates agglomerate-free processing of functional nanoparticles. Multifunctional extractor molecules were discovered and used as capping and reducing agents for particle synthesis or dispersing and charging agents for colloidal processing. The progress achieved in the development of extractors and extraction mechanisms has driven the advances in the surface modification and functionalization of materials. New PELLI techniques were used for the development of advanced materials and devices for optical, photovoltaic, energy storage, electronic, biomedical, sensor and other applications. PMID- 30293698 TI - Apostle Islands National Lakeshore: A Review of Search and Rescue and Emergency Medical Services Operations, 2006-2015. AB - INTRODUCTION: Apostle Islands National Lakeshore (APIS) lies at the northern tip of Wisconsin and is home to a network of 21 islands along Lake Superior. The goal of this report is to investigate search and rescue (SAR) and emergency medical services (EMS) trends at APIS in an effort to improve visitor safety and resource allocation. METHODS: This study is a retrospective analysis reviewing APIS SAR reports and annual EMS summary reports from January 1, 2006, to December 31, 2015. Information related to incident type, incident date, individual demographic characteristics and activities, injury/illness type, cost, and contributing factors were recorded and analyzed in frequency tables. RESULTS: From 2006 to 2015, APIS SAR conducted 133 total missions assisting 261 individuals-200 not injured/ill, 57 injured/ill, and 4 fatalities. Median cost per SAR incident involving aircraft totaled $21,695 (range: $2,993-141,849), whereas incidents not involving aircraft had a median cost of $363 (range: $35-8,830). Nonmotorized boating was the most common activity resulting in SAR incidents. All 4 fatalities were attributed to drowning while kayaking or swimming. Cold-related injury/illness accounted for nearly half of all injuries/illnesses (45%) with the most commonly reported contributing factor being high winds. EMS responded to a total of 134 incidents. Trauma and first aid accounted for 43% and 34% of EMS workload, respectively. CONCLUSIONS: Overall, this study highlights the hazards associated with the frigid and rough conditions of Lake Superior. The reported results aim to help APIS personnel more saliently convey risks to visitors and plan appropriately in an effort to decrease the need for future rescues. PMID- 30293699 TI - Emerging immunotherapeutic strategies targeting telomerases in genitourinary tumors. AB - Telomerase activity and telomere length are essential for the pathogenesis of several human diseases, including genitourinary tumors. Telomerase constitutes a complex system that includes human telomerase reverse transcriptase (hTERT), human telomerase RNA component (hTR) and telomerase associated protein 1 (TEP1), which are overexpressed in tumor cells compared to normal cells and are involved in the carcinogenesis and progression of renal cell carcinoma (RCC), bladder (BC) and prostate cancer (PCa). In addition, telomerase degraded peptide fragments expressed on the surface of tumor cells lead to their recognition by immune cells. On this scenario, in vitro and in vivo studies have shown effective anti tumor activity of hTERT-tailored strategies in genitourinary tumors, including active immunotherapy with hTERT-peptide vaccines and passive immunotherapy with hTERT-transduced T cell infusion. This review emphasizes the role of telomerase in the carcinogenesis and progression of genitourinary tumors, thus underlying the potential of emerging telomerase-tailored immunotherapies in these patients. PMID- 30293700 TI - Chondrosarcoma: An overview of clinical behavior, molecular mechanisms mediated drug resistance and potential therapeutic targets. AB - Sarcomas are known as a heterogeneous class of cancers arisen in the connective tissues and demonstrated various histological subtypes including both soft tissue and bone origin. Chondrosarcoma is one of the main types of bone sarcoma that shows a considerable deficiency in response to chemotherapy and radiotherapy. While conventional treatment based on surgery, chemo-and radiotherapy are used in this tumor, high rate of death especially among children and adolescents are reported. Due to high resistance to current conventional therapies in chondrosarcoma, there is an urgent requirement to recognize factors causing resistance and discover new strategies for optimal treatment. In the past decade, dysregulation of genes associated with tumor development and therapy resistance has been studied to find potential therapeutic targets to overcome resistance. In this review, clinical aspects of chondrosarcoma are summarized. Moreover, it gives a summary of gene dysregulation, mutation, histone modifications and non coding RNAs associated with tumor development and therapeutic response modulation. Finally, the probable role of tumor microenvironment in chondrosarcoma drug resistance and targeted therapies as a promising molecular therapeutic approach are summarized. PMID- 30293701 TI - Can we avoid the toxicity of chemotherapy in elderly cancer patients? AB - Although approximately 50% of cancer patients are 70 years of age or older, cancer treatment in the elderly remains a therapeutic challenge. The elderly form a very heterogeneous group in relation to their general health state, degree of dependence, comorbidities, performance status, physical reserve and geriatric situation, for which therapeutic decisions must be made in an individualized manner. In addition, changes in pharmacokinetics and pharmacodynamics of the drugs occur with age, as well as the tolerance of the tissues, leading to a narrowing of the therapeutic margin and an increase in toxicity. In the general population, Performace Status (PS) has traditionally been used to estimate tolerance to chemotherapy, but in the elderly population it is not useful. In this review we summarize the current knowledge about the pharmacology of antineoplastic drugs in the elderly and the tools available to help us identify risk of chemotherapy toxicity in these patients. PMID- 30293702 TI - Stereotactic body radiation therapy (SBRT) on renal cell carcinoma, an overview of technical aspects, biological rationale and current literature. AB - BACKGROUND: Stereotactic body radiotherapy (SBRT) is characterized by the delivery of high doses of ionizing radiation in few fractions. It is highly effective in achieving local control, and, due to the high biological effective dose administered, it seems to overcome the radioresistance of renal cell carcinoma (RCC). Thus, SBRT could constitute a treatment option for the management of localized RCC in patients who are not surgical candidates. In this paper, we report an overview about data from the current evidence about SBRT in patients affected by localized RCC. MATERIALS AND METHODS: A non-systematic review was performed, including data from both retrospective and prospective studies focusing on the use of SBRT for localized RCC and its biological rationale. Furthermore, ongoing trials on this issue are reported. CONCLUSION: Currently, SBRT might be considered a treatment alternative in inoperable patients affected by primary RCC. Currently, dose-escalation to 48 Gy in 3-4 fractions are effective and well tolerated. Emerging role of immune therapies in RCC patients warrant further studies to explore interactions between SBRT and immune response. PMID- 30293703 TI - Criteria for eligibility to cisplatin in the curative treatment of head and neck cancer: Consensus opinion from a panel of experts. AB - Squamous-cell carcinoma of the head and neck (SCCHN) is an important problem in Brazil, where epidemiological and socioeconomic features often create barriers to the implementation of combined modalities with curative potential. Cisplatin improves the efficacy of radiotherapy in the adjuvant treatment of localized SCCHN and in the definitive therapy of locally advanced disease. However, the addition of high-dose cisplatin to radiotherapy increases treatment toxicity and is not always warranted. A panel of experts convened in Sao Paulo, Brazil, for discussions and recommendations regarding the use of high-dose cisplatin in combination with radiotherapy in SCCHN. In addition to discussing their professional experience, panel members used the current literature to provide evidence-based, practical recommendations regarding sociodemographic or medical criteria that may preclude safe administration of cisplatin. It is hoped that the application of these recommendations in clinical practice may improve therapeutic results in Brazil and other countries with similar health-care environments. PMID- 30293704 TI - Revisiting the dynamic cancer stem cell model: Importance of tumour edges. AB - The lack of an effective treatment against cancer is not only due to its huge heterogeneity, but also to the fact that we don't have an answer to the question on how cancer originates. Among the proposed models to explain the development of cancer, the hierarchical model has been widely accepted. Nevertheless, this model fails to explain several experimental observations such as the cancer stem cells (CSCs) location inside a tumour or the differences between primary and metastatic tumours. Moreover, increasing evidence shows that the CSC phenotype is not a rigid state. Here, we present a critical review on the assumed tumour development models emphasizing the relevance of the dynamic and changing nature of cancer and the CSCs population in which the tumour microenvironment plays a crucial role and we propose a new model of tumour origin that could have an impact on new therapeutic strategies. PMID- 30293705 TI - The role of PDGF-B/PDGFR-BETA axis in the normal development and carcinogenesis of the breast. AB - PDGFs/PDGFRs axis is documented as an important tumor-promoting agent and potential therapeutic target for several human carcinomas, including breast cancer. However, little is known about the role played by the PDGF family members in the normal development of the breast tissue, breast carcinogenesis and tumor microenvironment dynamics Despite its potent pro-lymphangiogenic effects, PDGF B/PDGFR-beta axis remains controversial and incompletely elucidated in the field of breast cancer, with emphasis to its differential implications in breast cancer molecular subtypes. Although some data are available concerning this aspect, little or no information is found regarding the role of the PDGF-B/PDGFR-beta axis in rare and aggressive types of breast cancers, such as triple negative breast cancers (TNBCs) and its associated subtypes This review attempted to gather as many data as possible concerning PDGFs family members in the normal breast tissue and in breast carcinogenesis with special focus on their role in diagnosis and therapeutic approach. PMID- 30293706 TI - Duration of first-line treatment for metastatic colorectal cancer: Translating the available evidence into general recommendations for routine practice. AB - Over the last two decades the number of front-line regimens for metastatic colorectal cancer has progressively increased. Nevertheless, there is still no consensus on the optimal duration of treatment or the role of de escalated/maintenance strategies after induction chemotherapy. In this article we provide an overview of the studies that addressed the duration of first-line systemic treatment with cytotoxic agents plus or minus targeted therapies highlighting caveats and limitations of the same. Also, we try to translate the available evidence into practical recommendations that can be used in everyday practice to inform treatment decisions. The main conclusion of our review article is that continuing induction treatment until progression may improve disease control but there is no evidence to suggest that adopting this practice can prolong survival. On the other hand, de-escalated treatment strategies offer an opportunity to reduce the burden of toxicity while maintaining satisfactory oncological outcomes. PMID- 30293707 TI - Critical appraisal of oncological safety of stent as bridge to surgery in left sided obstructing colon cancer; a systematic review and meta-analysis. AB - This meta-analysis aims to determine the long-term oncological outcomes of SEMS as bridge to surgery (BTS) versus emergency surgery (ES). A systematic search without restrictions was conducted, and all studies comparing SEMS with ES reporting on long-term outcomes were included. Methodological quality was assessed using the appropriate tools. Twenty-one comparative studies were selected, reporting on 1919 patients. Meta-analysis showed no significant difference regarding three- and five-year overall survival (OR = 0.85 (0.68-1.08) and OR = 1.04 (0.68-1.57), respectively), disease-free survival (OR = 0.96 (0.73 1.26) and OR = 0.86 (0.54-1.36), respectively) and local recurrence rate (OR = 1.32 (0.78-2.23)). Permanent stomas were significantly lower in the SEMS group (OR 0.49 (0.32-0.74)). Sensitivity analysis on three-year survival showed opposite outcomes, with a trend towards worse survival in the SEMS group when only RCTs are taken into account. In conclusion, when in experienced hands, SEMS placement as BTS seems oncologically safe. PMID- 30293708 TI - C-MET as a potential target therapy toward personalized therapy in some pediatric tumors: An overview. AB - Althoughpediatric tumors represent less than 1% of all new cancer diagnoses, they still rank the second in the list of disease-related morbidity and mortality in children in the US. Combining biomarker-driven targeted therapy with individualized genomic analysis is the principle of precision medicine trials. The cellular-mesenchymal-epithelial transition (c-MET) factor receptor signaling pathway plays an important role in many physiological functions including embryological development. It, tightly, regulates changes in cell growth and survival, it also defines the general pattern of invasive growth during normal development. Aberrant MET signaling is the fundamental cause of carcinogenesis of many pediatric tumors and it may play a role in tumor metastasis that leads to the poor prognosis in most cancer patients. This review describes c MET/hepatocyte growth factor (HGF) signaling pathway relevance to pediatric tumors. Also, it discusses the pre-clinical and clinical studies for inhibitors of this pathway. PMID- 30293709 TI - The effects of mitochondria-associated long noncoding RNAs in cancer mitochondria: New players in an old arena. AB - LncRNAs, as new players in the old battle against cancer, are significant components of gene regulatory networks. Mitochondria-associated lncRNAs have newly been discovered to work in concert with transcription factors and epigenetic regulators to modulate mitochondrial gene expression and mitochondrial function. Many mitochondria-associated lncRNAs regulate mitochondrial biosynthesis, bioenergetics, apoptosis and possibly govern the cross-talk of mitochondria with nuclei. The complexity of mitochondria-associated lncRNAs is now just starting to envisage. In this review, we collected available evidence that reinforces the importance of mitochondria-associated lncRNA in cancer metabolism, apoptosis, and cell senescence. For the non-exhaustive list of mitochondria-associated lncRNAs, we identified 18 lncRNAs in total (mitochondria encoded lncRNAs or nuclei encoded mitochondria function associated lncRNAs) as emerging new players in cancer mitochondrial function. As lncRNAs exhibit cancer type-specific expression patterns, they are attractive targets for selective therapeutic interventions. Manipulation of their function may thus represent a valuable strategy for future cancer treatment. PMID- 30293710 TI - The Era of PARP inhibitors in ovarian cancer: "Class Action" or not? A systematic review and meta-analysis. AB - INTRODUCTION: Carboplatin is the milestone of epithelial ovarian cancer (EOC) treatment, thus response to platinum is the major prognostic factor. Among platinum-sensitive patients, 40% carry a germline or somatic BRCA1/2 mutation. In this scenario a new class of drugs, the PARP inhibitors (PARPis), produced a significant improvement in long-term disease control. In order to make an aggregate evaluation of the impact of these agents, we performed a systematic review and meta-analysis. PATIENTS AND METHODS: Clinical trials were selected by searching "Pubmed" database and abstracts from major cancer meetings. We considered the January 2008 - April 2018 time frame. Progression free survival (PFS) was the primary end-point, toxicities were secondary end-points. Hazard ratios (HRs) of PFS, with confidence intervals, and risk ratios of grade 3-4 toxicity rates, were extracted from retrieved studies and included in the current analysis. Meta-analysis was carried out by the fixed and random effect models. We conducted this meta-analysis to also compare indirectly the efficacy of different PARPis in EOC patients. RESULTS: Five randomized trials for a total of 1839 patients were selected and included in the final analysis. In particular, we evaluated a BRCA-mutant cohort (871 patients) with a pooled HR 0.25 (95%CI 0.21 0.31) and the BRCA-wild type cohort (836 patients) with a pooled HR 0.41 (95%CI 0.31-0.55), respectively. Regarding safety profile, no significant differences were detected in all grade toxicities, however, taking into account 3-4 grade toxicities and SAEs (severe adverse events), we show that rucaparib-treated patients reported major abdominal pain events, while niraparib-treated patients were associated with the highest percentage of haematological toxicities, hypothesizing a drug effect for the safety analysis. In the indirect comparisons, significant differences were not detected on PFS for the different agents. CONCLUSIONS: We confirm a significant benefit in survival outcome of PARPis for EOC patients with a "class effect" on the bases of narrow CI and indirect comparisons in the different groups. Therefore, we underline that this strategy is of special value in BRCA-mutated patients because genetic testing allows best patient selection for all PARPis with the added value of individualized prevention in familiars.

AB - Advances in anticancer therapies and increasing attention towards patient quality of life make Supportive Care in Cancer (SCC) a key aspect of excellence in oncological care. SCC promotes a holistic conception of quality of life encompassing clinical, ethical/existential, and spiritual dimensions. Despite the calls of international oncology societies empirical evidence shows that SCC has not yet been implemented. More efforts are needed given the clinical and ethical value of SCC not only for patients, but also for clinicians and hospitals. Drawing on different literature sources, we identify and discuss three important barriers to the implementation of SCC: 1) organisational - lack of adequate resources and infrastructures in over-stretched clinical environments, 2) professional- burnout of cancer clinicians; and 3) cultural - stigma towards death and dying. We add an ethical counselling framework to the SCC implementation toolkit- which, could offer a flexible and resource-light way of embedding SCC, addressing these barriers.

AB - Triple-negative breast cancer (TNBC) (estrogen receptor-negative, progesterone receptor-negative, and HER2-negative) is viewed as an aggressive subgroup of breast cancer. Treating patients with TNBC remains clinically challenging. It's now well established than radiation therapy is able to improve locoregional control in breast cancer patients both after breast conserving surgery or mastectomy, with positive impact in high-risk patients for long-term survival. Biologic characterization of breast tumor different subtypes, in particular the heterogeneous subtype of TNBC could permit to adapt the treatment plan. In the present review, summarizing the molecular types, we describe clinical features and postoperative radiotherapy current situation for TNBC, and we provide new strategies and directions through an adapted radiation therapy. PMID- 30293713 TI - Treatment of gynaecological cancer related lower limb lymphoedema with liposuction. AB - OBJECTIVE: To evaluate outcomes in patients with gynaecological cancer related lymphoedema treated with liposuction. METHODS: A prospective analysis of 21 patients who underwent liposuction followed by compression therapy for chronic unilateral lower limb lymphoedema with up to 8 years follow up was performed. RESULTS: Duration of lymphoedema prior to liposuction ranged from 4 to 28 years (mean 15.2 years). The mean age at time of liposuction was 52 years (range 37 67). Estimated volume excess in the affected limb ranged from 1.6 to 12 l (mean 4.7 l). The mean percentage reduction was 92.6% at 6 months (range 59.4-159.9) and 88.9% (range 60.9-127.5) at 1 year. Longer term follow-up of 6 patients at 5 years post-liposuction revealed a mean percentage reduction of 113.6% (range 83.5 155.5). CONCLUSION: Our experience of liposuction combined with compression garments has demonstrated significant and sustainable reduction in limb volume in patients with lower limb lymphoedema secondary to gynaecological malignancy. PMID- 30293714 TI - Influence of dietary protein intake on body composition in chronic kidney disease patients in stages 3-5: A cross-sectional study. AB - INTRODUCTION: A controlled protein intake has shown beneficial effects to preserve renal function and nutritional status in chronic kidney disease (CKD) patients. This study aimed to analyze usual dietary protein intake and its potential contribution to body composition in CKD patients in stages 3-5. METHOD: Cross-sectional study in 134 CKD patients in stages 3-5 (mean e-GFR: 19.4+/ 8.7ml/min/1.73m2; males 68.7% and primary CKD etiology was diabetes mellitus, 35.8%). Demographic, clinical and nutritional parameters were evaluated. Normalized protein nitrogen appearance (nPNA), was used as a surrogate marker of dietary protein intake. The sample was classified into three nPNA groups (Gn): G1: <0.8g/kg/day; G2: 0.8-1g/kg/day and, G3: >=1g/kg/day. Assessment of nutritional status using the malnutrition-inflammation score (MIS), anthropometric measures and laboratory parameters. Analysis of body composition and hydration status by bioelectrical impedance analysis (BIVA-101-RJL system). Statistical analysis by SPSS v.20. RESULTS: Overall mean nPNA values were 0.91+/ 0.23g of protein/kg BW/day and only 32.1% had a dietary protein intake <0.8g of protein/kg BW/day. Most of the CKD patients (65.5%) were in stages 4 or 5. Prevalence of protein-energy-wasting (PEW) syndrome measured by MIS was 15%. By analyzing differences between nPNA groups, body weight (BW), BMI and triceps skinfold (TSF) thickness were significantly higher in the group with nPNA >=1g/kg BW/day (G3), whereas a significant inverse relationship was found with the percentages of body cell mass (BCM%), fat-free mass (FFM%), muscle mass (MM%) and phase angle (PA) in the group with the lowest nPNA (G1). Analysis of gender among subjects showed significant differences with BW, FFM%, TSF and mid-arm muscle circumference (MAMC%). Linear regression analysis showed that resistance, BCM%, MM%, and serum albumin were significant predictors of nPNA as a surrogate marker of daily protein intake (R=0.51; R2=0.29; R2 adjusted=0.23; p<0.001). CONCLUSION: Controlled protein intake is one of the cornerstones of treatment in CKD patients. A low protein intake in patients with CKD stages 3 and 4-5 was associated with loss of muscle mass in the advanced-CKD unit. The loss of muscle mass appears as an early indicator of nutritional comprised. Factors such, elderly age and loss of eGFR, showed lower protein intake and were associated with muscle loss, especially in women. Further longitudinal studies are required to evaluate the contribution of different protein intakes to uremic symptoms, nutritional status, body composition and CKD progression.

Genetic models of tumor formation have been used to explore how combinations of mutations cooperate to promote tumor formation in vivo. Here, we identify lactate dehydrogenase (LDH), a key enzyme in Warburg effect metabolism, as a cooperating factor that is both necessary and sufficient for epidermal growth factor receptor (EGFR)-driven epithelial neoplasia and metastasis in a Drosophila model. LDH is upregulated during the transition from hyperplasia to neoplasia, and neoplasia is prevented by LDH depletion. Elevated LDH is sufficient to drive this transition. Notably, genetic alterations that increase glucose flux, or a high-sugar diet, are also sufficient to promote EGFR-driven neoplasia, and this depends on LDH activity. We provide evidence that increased LDHA expression promotes a transformed phenotype in a human primary breast cell culture model. Furthermore, analysis of publically available cancer data showed evidence of synergy between elevated EGFR and LDHA activity linked to poor clinical outcome in a number of human cancers. Altered metabolism has generally been assumed to be an enabling feature that accelerates cancer cell proliferation. Our findings provide evidence that sugar metabolism may have a more profound role in driving neoplasia than previously appreciated. PMID- 30293716 TI - Intraflagellar Transport Complex A Genes Differentially Regulate Cilium Formation and Transition Zone Gating. AB - Cilia are found on most eukaryotic cell types, serving motility, environment sensing, and signaling (cell-cell) functions, and defects cause genetic diseases (ciliopathies), affecting the development of many tissues [1]. Cilia are built by intraflagellar transport (IFT), a bidirectional microtubule-based motility driven by kinesin-2 anterograde (toward ciliary tip) and IFT-dynein retrograde (toward ciliary base) motors together with IFT-A and IFT-B cargo adaptor complexes that control retrograde and anterograde IFT, respectively [2]. Ciliary composition is also facilitated by the transition zone (TZ) at the ciliary base and the associated Meckel-Gruber syndrome (MKS) and nephronophthisis (NPHP) modules that establish protein diffusion barriers and regulate cilium structure [3]. Although the molecular architecture of the IFT machine is emerging [2], how individual components contribute to cilium subtype formation and IFT remains relatively unexplored, especially in vivo. In addition, little is known about functional interactions between IFT and TZ modules. Here, in Caenorhabditis elegans (roundworms), we identify cell-type-specific mechanisms by which IFT-A sculpts the structures of discrete ciliary subtypes and regulates IFT. We also uncover differential roles for IFT-A subunits in controlling the TZ restriction of MKS module components and ciliary exclusion (gating) of periciliary membrane proteins, with IFT-140 controlling their ciliary entry and IFT-43/121/139 controlling their ciliary removal. Furthermore, we determine that IFT-A and MKS module components synergistically interact to determine cilium structure. Overall, this work provides insight into the functional architecture of a metazoan IFT-A complex in different cell types and uncovers new relationships between ciliopathy-associated IFT-A and TZ modules. PMID- 30293717 TI - Distinct Predatory Behaviors in Scimitar- and Dirk-Toothed Sabertooth Cats. AB - Over the Cenozoic, large cat-like forms have convergently evolved into specialized killers of "megaherbivores" that relied on their large, and laterally compressed (saber-like) canines to rapidly subdue their prey [1-5]. Scimitar- and dirk-toothed sabertooths are distinct ecomorphs that differ in canine tooth length, degree of serration, and postcranial features indicative of dissimilar predatory behavior [6-13]. Despite these differences, it is assumed that they used a similar "canine-shear" bite to kill their prey [14, 15]. We investigated the killing behavior of the scimitar-toothed Homotherium serum and the dirk toothed Smilodon fatalis using a comparative sample of living carnivores and a new quantitative approach to the analysis of skull function. For the first time, we quantified differences in the relative amount and distribution of cortical and trabecular bone in coronal sections of skulls to assess relative skull stiffness and flexibility [16-19]. We also use finite element analysis to simulate various killing scenarios that load skulls in ways that likely favor distinct proportions of cortical versus trabecular bone across the skull. Our data reveal that S. fatalis had an extremely thick skull and relatively little trabecular bone, consistent with a large investment in cranial strength for a stabbing canine shear bite. However, H. serum had more trabecular bone and most likely deployed an unusual predatory behavior more similar to the clamp-and-hold technique of the lion than S. fatalis. These data broaden the killing repertoire of sabertooths and highlight the degree of ecological specialization among members of the large carnivore guild during the Late Pleistocene of North America. PMID- 30293718 TI - Modularity and Overcompensatory Growth in Ediacaran Rangeomorphs Demonstrate Early Adaptations for Coping with Environmental Pressures. AB - The first known diverse, complex, macroscopic benthic marine ecosystems (late Ediacaran, ca. 571-541 Ma) were dominated by the Rangeomorpha, an enigmatic group of extinct frondose eukaryotes that are candidate early metazoans [1, 2]. The group is characterized by a self-similar branching architecture that was most likely optimized for exchange, but nearly every other aspect of their biology is contentious [2-4]. We report locally enhanced, aberrant growth ("eccentric branching") in a stalked, multifoliate rangeomorph-Hylaecullulus fordi n. gen., n. sp.-from Charnwood Forest (UK), confirming the presence of true biological modularity within the group. Random branches achieve unusually large proportions and mimic the architecture of their parent branch, rather than that of their neighbors (the norm). Their locations indicate exceptional growth at existing loci, rather than insertion at new sites. Analogous overcompensatory branching in extant modular organisms requires the capacity to orchestrate growth at specific sites and occurs most frequently in response to damage or environmental stress, allowing regeneration toward optimum morphology (e.g., [5-7]). Its presence in rangeomorphs indicates a hitherto unappreciated level of control to their growth plan, a previously unrecognized form of morphological plasticity within the group, and an ability to actively respond to external physical stimuli. The trait would have afforded rangeomorphs resilience to fouling and abrasion, partially accounting for their wide environmental tolerance, and may have pre-adapted them to withstand predation, weakening this argument for their extinction. Our findings highlight that multiple, phylogenetically disparate clades first achieved large size through modularity. PMID- 30293719 TI - Prevalence of Mutation-Prone Microhomology-Mediated End Joining in a Chordate Lacking the c-NHEJ DNA Repair Pathway. AB - Classical non-homologous end joining (c-NHEJ), a fundamental pathway that repairs double-strand breaks in DNA, is almost universal in eukaryotes and involves multiple proteins highly conserved from yeast to human [1]. The genes encoding these proteins were not detected in the genome of Oikopleura dioica, a new model system of tunicate larvaceans known for its very compact and highly rearranged genome [2-4]. After showing their absence in the genomes of six other larvacean species, the present study examined how O. dioica oocytes and embryos repair double-strand DNA breaks (DSBs), using two approaches: the injection of linearized plasmids, which resulted in their rapid end joining, and a newly established CRISPR Cas9 technique. In both cases, end joining merged short microhomologous sequences surrounding the break (mainly 4 bp long), thus inducing deletions larger than for the tunicate ascidian Ciona intestinalis and human cells. A relatively high frequency of nucleotide insertions was also observed. Finally, a survey of genomic indels supports the involvement of microhomology mediated repair in natural conditions. Overall, O. dioica repairs DSBs as other organisms do when their c-NHEJ pathway is experimentally rendered deficient, using another mode of end joining with the same effect as alternative NHEJ (a NHEJ) or microhomology-mediated end joining (MMEJ) [5-7]. We discuss how the exceptional loss of c-NHEJ and its replacement by a more mutation-prone mechanism may have contributed to reshaping this genome and even been advantageous under pressure for genome compaction. PMID- 30293720 TI - Wild Birds Learn Songs from Experimental Vocal Tutors. AB - In eight groups of animals, including humans and songbirds, juveniles are understood to learn vocalizations by listening to adults [1-4]. Experimental studies of laboratory-reared animals support this hypothesis for vocal learning [5-7], yet we lack experimental evidence of vocal learning in wild animals. We developed an innovative playback technology involving automated loudspeakers that broadcast songs with distinctive acoustic signatures. We used this technology to simulate vocal tutors in the wild and conducted year-long tutoring sessions to five cohorts of free-living migratory Savannah Sparrows in eastern Canada. We confirm that wild birds learn songs by listening to adult conspecific animals, and we show that they pass these songs on to subsequent generations. Further, we provide the first experimental evidence in the wild that the timing of exposure to tutor song influences vocal learning: wild Savannah Sparrows preferentially learn songs heard during both their natal summer and at the outset of their first breeding season. This research provides direct experimental evidence of song learning by wild animals and shows that wild birds learn songs during two critical stages of development early in life. VIDEO ABSTRACT. PMID- 30293722 TI - A Human Polymorphism in CHRNA5 Is Linked to Relapse to Nicotine Seeking in Transgenic Rats. AB - Tobacco addiction is a chronic and relapsing disorder with an important genetic component that represents a major public health issue. Meta-analysis of large scale human genome-wide association studies (GWASs) identified a frequent non synonymous SNP in the gene coding for the alpha5 subunit of nicotinic acetylcholine receptors (alpha5SNP), which significantly increases the risk for tobacco dependence and delays smoking cessation. To dissect the neuronal mechanisms underlying the vulnerability to nicotine addiction in carriers of the alpha5SNP, we created rats expressing this polymorphism using zinc finger nuclease technology and evaluated their behavior under the intravenous nicotine self-administration paradigm. The electrophysiological responses of their neurons to nicotine were also evaluated. alpha5SNP rats self-administered more nicotine at high doses and exhibited higher nicotine-induced reinstatement of nicotine seeking than wild-type rats. Higher reinstatement was associated with altered neuronal activity in several discrete areas that are interconnected, including in the interpeduncular nucleus (IPN), a GABAergic structure that strongly expresses alpha5-containing nicotinic receptors. The altered reactivity of IPN neurons of alpha5SNP rats to nicotine was confirmed electrophysiologically. In conclusion, the alpha5SNP polymorphism is a major risk factor for nicotine intake at high doses and for relapse to nicotine seeking in rats, a dual effect that reflects the human condition. Our results also suggest an important role for the IPN in the higher relapse to nicotine seeking observed in alpha5SNP rats. PMID- 30293721 TI - Shugoshin Is Essential for Meiotic Prophase Checkpoints in C. elegans. AB - The conserved factor Shugoshin is dispensable in C. elegans for the two-step loss of sister chromatid cohesion that directs the proper segregation of meiotic chromosomes. We show that the C. elegans ortholog of Shugoshin, SGO-1, is required for checkpoint activity in meiotic prophase. This role in checkpoint function is similar to that of conserved proteins that structure meiotic chromosome axes. Indeed, null sgo-1 mutants exhibit additional phenotypes similar to that of a partial loss-of-function allele of the axis component, HTP-3: premature synaptonemal complex disassembly, the activation of alternate DNA repair pathways, and an inability to recruit a conserved effector of the DNA damage pathway, HUS-1. SGO-1 localizes to pre-meiotic nuclei when HTP-3 is present but not yet loaded onto chromosome axes and genetically interacts with a central component of the cohesin complex, SMC-3, suggesting that it contributes to meiotic chromosome metabolism early in meiosis by regulating cohesin. We propose that SGO-1 acts during pre-meiotic replication to ensure fully functional meiotic chromosome architecture, rendering these chromosomes competent for checkpoint activity and normal progression of meiotic recombination. Given that most research on Shugoshin has focused on its regulation of sister chromatid cohesion during chromosome segregation, this novel role may be conserved but previously uncharacterized in other organisms. Further, our findings expand the repertoire of Shugoshin's functions beyond coordinating regulatory activities at the centromere. PMID- 30293723 TI - Spillovers from the Patient Protection and Affordable Care Act to employer sponsored dental insurance enrollment. AB - BACKGROUND: Previous study results have indicated that the Patient Protection and Affordable Care Act (ACA) health insurance expansion for dependents (called the dependent coverage expansion) also led to a dental insurance expansion for dependents. In this study, the author examines whether this expansion is due to changes in employer-sponsored dental insurance. METHODS: The author compared enrollment and oral health care use between 2 groups of young adults in employer sponsored dental plans managed by Delta Dental of Michigan before and after the initial implementation of the ACA: adults aged 20 through 24 years (eligible for the expansion) and adults aged 30 through 34 years (ineligible). RESULTS: The ACA dependent coverage expansion led to an increase in both dental plan enrollment rates (5.38%; P < .01) and oral health care use rates (3.57%; P < .1) among adults aged 20 through 24 years relative to adults aged 30 through 34 years. CONCLUSIONS: Although the ACA's dependent coverage expansion led to an increase in dental plan enrollment and oral health care use in Michigan, the effects seen by other insurers and states are yet to be determined, although the direction likely is similar. PRACTICAL IMPLICATIONS: This study's results suggest that employers responded to the ACA dependent coverage expansion by expanding dependent oral health care coverage. PMID- 30293724 TI - APOE E4, rs405509, and rs440446 promoter and intron-1 polymorphisms and dementia risk in a cohort of elderly Finns-Helsinki Birth Cohort Study. AB - We tested if the epsilon4 major isoform of the APOE gene and rs405509 and rs440446 promoter and intron-1 polymorphisms predicted risk of any dementia or Alzheimer's disease with diagnoses derived from the Hospital Discharge and Causes of Death Registers in 1453 participants of the Helsinki Birth Cohort Study. We used Cox proportional hazard models adjusted for sex, year of birth, maximum lifetime occupational status and education, and diagnoses of stroke, coronary heart disease, mood disorders, and depressive symptoms. APOE epsilon4 predicted higher risk of any dementia (hazard ratios >3.68; 95% confidence interval [CI] 1.76, 7.70) across all statistical models, and when adjusted for rs405509 and rs440446. The number of minor alleles in rs405509 or rs440446 was not associated with dementia risk (hazard ratios<1.43; 95% CI 0.87, 2.36). As rs405509 or rs440446 has been associated with nonpathological cognitive aging in this and other cohorts independent of the APOE major isoforms, these findings lend credence that APOE locus may be linked with dementia risk and nonpathological cognitive aging via separate mechanisms. PMID- 30293725 TI - Relationship between variants of 17 newly loci and Parkinson's disease in a Chinese population. AB - Genetic factors play significant roles in the causes of Parkinson's disease (PD). Recently, a meta-analysis of genome-wide association study (GWAS) has identified 17 loci associated with PD. The objective of our study was to investigate the association of 17 single-nucleotide polymorphisms with the risk of PD in Chinese population. We performed a case-control association study, and 1189 subjects comprising 652 PD patients and 537 controls were genotyped by using a Mass ARRAY System or a TaqMan assay. We found that rs601999 (OR (95% CI) = 3.378 (2.273 5.051), p < 0.001), rs11343 (OR (95% CI) = 0.426 (0.210-0.862), p = 0.018), rs353116 (OR (95% CI) = 0.738 (0.577-0.943), p = 0.015), and rs2280104 (OR (95% CI) = 1.371 (1.078-1.743), p = 0.010) were significantly associated with PD in Chinese population. However, no significant association was found in the remaining 13 single-nucleotide polymorphisms between both groups. PMID- 30293727 TI - Safety of Radioembolization in the Setting of Angiographically Apparent Arterioportal Shunting. AB - PURPOSE: To retrospectively analyze adverse events (AE) in patients with hepatocellular carcinoma (HCC) treated with yttrium-90 radioembolization in the setting of angiographically apparent arterioportal shunts (APSs). MATERIALS AND METHODS: Thirty-two patients with HCC underwent radioembolization with APSs from January 2011 to September 2016, totaling 34 administrations using resin (6) and glass (28) microspheres. APSs were graded angiographically as segmental (9), ipsilobar (15), contralobar (7), or main portal (2), according to portal perfusion. Tumors were categorized as solitary (9), multifocal (7), or infiltrative (16). Both unilobar (25) and bilobar (7) disease was treated. Child Pugh Score was A (22), B (10), or C (2), with a median Model for End-Stage Liver Disease (MELD)/Na-MELD of 8/8.5. Median procedure dose was 132.6 Gy. AEs were graded using Combined Terminology Criteria for Adverse Events (CTCAE) version 4.0. Tumor response was assessed using the modified Response Evaluation Criteria in Solid Tumors (mRECIST). RESULTS: CTCAE grade >=3 AEs were observed in 22% of patients. Barcelona Clinic Liver Cancer (BCLC) C patients with nonsegmental shunts who received lobar administrations had a grade >=3 AE rate of 38% compared with the remaining cohort, which was 12% (P = .076). No events were reported in patients with segmental shunts (P = .023). Imaging analysis revealed mRECIST complete response (17), partial response (13), stable disease (3), and progressive disease (1). Overall survival at 6 months and 12 months was 72% and 57%, respectively. CONCLUSIONS: Radioembolization in the setting of APS may have a higher AE profile than reported literature when BCLC-C patients with nonsegmental shunts receive lobar administrations. Segmental shunts are generally well tolerated. PMID- 30293726 TI - A Comparison between Prethoracoscopy Localization of Small Pulmonary Nodules by Means of Medical Adhesive versus Hookwire. AB - PURPOSE: To compare prethoracoscopy localization of small pulmonary nodules (SPNs) by means of medical adhesive versus hookwire. MATERIALS AND METHODS: One hundred seven patients who underwent video-assisted thoracoscopic surgery resection for SPNs were consecutively recruited in this retrospective cohort study. Patients were divided into 2 groups according to the material used for localization of the SPNs: the medical adhesive group (n = 88) and the hookwire group (n = 19). The baseline data were collected, and operation waiting time (OWT; the time gap between localization and surgery), wedge resection performing time (WRPT), pathologic result, and complications of the 2 groups were assessed. RESULTS: All SPNs were successfully marked. No differences in pathologic result (P = .676), wedge resection, or segmentectomy rate (P = .679) were observed. OWT was markedly longer in the medical adhesive group than in the hookwire group (P < .001), whereas WRPT was similar in the 2 groups (P = .926). There were significantly (P = .004) fewer complications in the medical adhesive group (37.42%) than in the hookwire group (15.79%). Regarding individual complications, hemorrhage occurred significantly less in the medical adhesive group than in the hookwire group (9% vs 68%; P < .001), and no differences of cough, pneumothorax, or chest pain were found between the 2 groups (all P > .05). Multivariate logistic regression analysis further validated that hookwire was independently correlated with a higher risk of complication occurrence (P = .008) and hemorrhage occurrence (P < .001) compared with medical adhesive. CONCLUSIONS: Compared with hookwire, localization via medical adhesive can achieve a flexible time gap between localization and surgery. It also decreases the complication rate and increases convenience owing to no need for an anchor hook. PMID- 30293728 TI - Para-Axial Central Venous Stent Placement in Patients with Malignant Central Venous Obstruction with a Venous Port. AB - The authors performed a para-axial central venous stent (p-CVS) placement in 38 patients and implanted the stent without having to remove the functioning port. No difficulties were experienced in catheter function with p-CVS. In-stent stenosis was seen in 6 of 24 patients in the p-CVS group and in 6 of 18 patients in the intrastent venous stent placement group (P = .333). No complications occurred in any patient with p-CVS when the venous port was removed. Thus, p-CVS can be an alternative way to insert a CVS in patients who already have a functioning venous port. PMID- 30293729 TI - Characterizing the Impact of Women in Academic IR: A 12-Year Analysis. AB - PURPOSE: To determine the representation of female interventional radiology (IR) investigators and elucidate possible gender-specific disparities. MATERIALS AND METHODS: We analyzed 4,884 original, peer-reviewed articles from 2006-2017 in the Journal of Vascular and Interventional Radiology and CardioVascular and Interventional Radiology. Data abstraction and statistical analysis were performed for first and senior author gender, citations, and grants. RESULTS: We found that 84% of first authors and 91.4% of senior authors were male (P < .01). No significant difference was observed versus expected in terms of author gender collaboration combinations (P = 1.00). Each year reflected a 0.3%-0.4% increase in articles published by women (first author: B-value: 0.3, P = .05; senior author: B-value: 0.4, P = .01). No difference was observed in citations or grants received between genders. Female authors received increasing citations and grants each year (citations: first author: B-value: 0.24, P = .05; senior author: B value: 0.16, P = .15; grants: B-value: 0.88, P = .02). CONCLUSIONS: Women are equally as productive as men as determined by metrics such as number of publications, citations, and grants and are proportionally represented in the literature. No data indicating collaborative or citation/grant discrimination were observed, suggesting that the academic IR community is inclusive of its female constituents and equally respects their research contributions. Based on the statistically significant increases in female authorship observed in this 12 year study, this article reports encouraging trends for the future of women in interventional radiology. PMID- 30293730 TI - Duplicated Prostate Artery Central Gland Blood Supply: A Retrospective Analysis and Classification System. AB - Angiograms and cone-beam computed tomography scans of 36 consecutive prostate artery embolization patients (72 hemipelves) between October 2014 and February 2018 were reviewed. The hemipelves were classified according to the presence of dual central gland (CG) blood supply and the pattern of vascularization: Type 1 with a single CG blood supply (83.3%; n = 60); Type 2 with 2 independent CG arteries with overlapping territories (9.7%; n = 7); and Type 3 with 2 independent CG arteries with isolated territories (7%; n = 5). Up to 20% of pelvic sides may have more than 1 independent CG prostate artery that should be searched for during prostate artery embolization. PMID- 30293731 TI - Comparison between Surgical and Endovascular Hemodialysis Arteriovenous Fistula Interventions and Associated Costs. AB - PURPOSE: To compare: (i) rate of arteriovenous fistula (AVF) interventions in both incident and prevalent end-stage kidney disease patients; (ii) their associated costs; and (iii) intervention-free survival between patients with surgical hemodialysis arteriovenous fistula (SAVF) versus those with an endovascularly created fistula (endoAVF). MATERIALS AND METHODS: Data from the United States Renal Data System (USRDS) were abstracted to determine the rate of AVF interventions performed in the first year and associated costs (based on Medicare payment rates) for SAVFs created from 2011 to 2013 in the incident and prevalent patient cohorts. Comparative data for endoAVF were obtained from the Novel Endovascular Access Trial (NEAT). Event rates, intervention-free survival, and costs were compared between endoAVF and SAVF cohorts after 1:1 propensity score (PS) matching. RESULTS: In the matched incident patients, the event rate was 0.74 per patient-year (PY) for endoAVF versus 7.22/PY for SAVF (P < .0001), with a difference in expenditures of $16,494. Similarly, in matched prevalent patients the event rate was 0.46/PY for endoAVF vs 4.10/PY for SAVF (P < .0001), resulting in a cost difference of $13,389. Time-to-event analysis showed that at 1 year, 70% of endoAVF patients experienced freedom from intervention versus only 18% of SAVF patients for incident patients; these numbers were 62% and 18% for endoAVF and SAVF prevalent patients, respectively (P < .0001 for both). CONCLUSIONS: Both incident and prevalent patients with endoAVF required fewer interventions and had lower costs within the first year compared with matched patients with SAVF. PMID- 30293732 TI - Single-Center Retrospective Review of Radiofrequency Wire Recanalization of Refractory Central Venous Occlusions. AB - PURPOSE: To retrospectively review the effectiveness and safety of radiofrequency (RF) wire recanalization of refractory central venous occlusions (CVOs) and compare recurrent and nonrecurrent CVOs in terms of patient and occlusion characteristics. MATERIALS AND METHODS: Twenty CVOs were treated in 18 patients (age 40 y +/- 13; 9 women) with 11 superior vena cava (SVC) or brachiocephalic vein occlusions (ie, supradiaphragmatic) and 9 inferior vena cava or iliac vein occlusions (ie, infradiaphragmatic). Indications included pain, edema, ulceration, and/or dialysis arteriovenous fistula dysfunction peripheral to the CVO(s). All patients had multiple venous thrombotic risk factors, including mechanical venous compression, endothelial injury, and/or coagulopathies. CVO traversal was first attempted with standard and advanced techniques before RF wire recanalization and followed up with computed tomographic venography and clinic visits approximately 1, 3, 6, and 12 months after treatment. RESULTS: Sixteen CVOs (80%) were successfully transversed and associated with symptom relief. One major complication occurred involving SVC perforation into the pericardial space. Primary CVO patency rate was 56% at a median follow-up of 14.1 months (interquartile range [IQR], 9.2-20.0 mo). Recurrent CVOs tended to be infradiaphragmatic (71% vs 12% for supradiaphragmatic; P = .02), longer (12.9 cm +/- 10.0 vs 2.3 cm +/- 1.3; P < .01), and associated with implanted venous stents, filters, or cardiac pacer/defibrillator leads (86% vs 22%; P = .01). Median time to restenosis/occlusion was 1.5 months (IQR, 1.1-6.1 mo). CONCLUSIONS: RF wire recanalization is a relatively effective and safe option for refractory CVOs. Patients with longer, infradiaphragmatic CVOs associated with indwelling devices may require closer follow-up for CVO recurrence. PMID- 30293733 TI - Modified Rat Hepatocellular Carcinoma Models Overexpressing Vascular Endothelial Growth Factor. AB - PURPOSE: To compare tumor vascularity in 4 types of rat hepatocellular carcinoma (HCC) models: N1S1, vascular endothelial growth factor (VEGF)-transfected N1S1 (VEGF-N1S1), McA-RH7777, and VEGF-transfected McA-RH7777 (VEGF-McA-RH777) tumors. MATERIALS AND METHODS: The N1S1 and McA-RH7777 cell lines were transfected with expression vectors containing cDNA for rat VEGF. Eighty-eight male Sprague-Dawley rats (weight range, 400-450 g) were randomly divided into 4 groups (ie, 22 rats per model), and 4 types of tumor models were created by using the N1S1, VEGF N1S1, McA-RH7777, and VEGF-McA-RH777 cell lines. Tumor vascularity was evaluated by perfusion computed tomography (CT), enzyme-linked immunosorbent assay of VEGF, CD34 staining, angiography, and Lipiodol transarterial embolization. Intergroup discrepancies were evaluated by Kruskal-Wallis test. RESULTS: Arterial perfusion (P < .001), portal perfusion (P = .015), total perfusion (P < .001), tumor VEGF level (P = .002), and microvessel density (MVD; P = .007) were significantly different among groups. VEGF-McA-RH7777 tumors showed the greatest arterial perfusion (46.7 mL/min/100 mL +/- 15.5), total perfusion (60.7 mL/min/100 mL +/- 21.8), tumor VEGF level (3,376.7 pg/mL +/- 145.8), and MVD (34.50/00 +/- 7.5). Whereas most tumors in the N1S1, VEGF-N1S1, and McA-RH7777 groups showed hypovascular staining on angiography and minimal Lipiodol uptake after embolization, 5 of 6 VEGF-McA-RH7777 tumors (83.3%) presented hypervascular tumor staining and moderate to compact Lipiodol uptake. CONCLUSIONS: McA-RH7777 tumors were more hypervascular than N1S1 tumors, and tumor vascularity was enhanced further by VEGF transfection. Therefore, the VEGF-McA-RH7777 tumor is recommended to mimic hypervascular human HCC in rats. PMID- 30293734 TI - Feasibility of Boosted Radioembolization for Hepatocellular Carcinoma Larger than 5 cm. AB - PURPOSE: To address the feasibility of yttrium-90 (90Y) glass microspheres administered at a boosted dose in large hepatocellular carcinomas (HCCs). MATERIALS AND METHODS: From July 2016 to August 2017, 20 patients who underwent 90Y radioembolization for treatment-naive HCC met the following inclusion criteria: (i) nodular tumor, (ii) tumor size > 5 cm, (iii) Barcelona Clinic Liver Cancer stage A/B disease, (iv) target perfused tissue dose > 150 Gy, and (v) all tumors treated in 1 session of radioembolization. Follow-up radiologic findings and clinical outcomes were retrospectively reviewed until May 2018. Tumor response was determined per modified Response Evaluation Criteria In Solid Tumors. RESULTS: Mean total radiation activity infused was 4.96 GBq +/- 1.82 (median, 4.88 GBq; range, 1.63-9.15 GBq). Mean target perfused tissue dose was 263.5 Gy +/- 95.2 (median, 241.6 Gy; range, 156.2-550.6 Gy). The mean number of vials used per treatment was 4.15 +/- 1.4 (median, 4; range, 2-7). Complete response rates were 25% at 1 month and 60% at 3 months. Complete response of the primary index tumor was achieved in 16 patients (80%) based on best tumor response. Local progression-free survival and progression-free survival rates were 94.1% and 85.0% at 6 mo and 94.1% and 74.7% at 1 year, respectively. Four patients (20%) had symptomatic (n = 3) or asymptomatic (n = 1) benign biliary strictures. CONCLUSIONS: Radioembolization with a boosted dose in patients with large HCCs may show favorable tumor response, but with considerable biliary complications. PMID- 30293735 TI - Patient and Facility Demographics Related Outcomes in Early-Stage Non-Small Cell Lung Cancer Treated with Radiofrequency Ablation: A National Cancer Database Analysis. AB - PURPOSE: To determine facility and patient demographics associated with survival in early-stage non-small cell lung cancer (NSCLC) treated with radiofrequency (RF) ablation. MATERIALS AND METHODS: The National Cancer Database was queried for cases of stage 1a NSCLC treated with RF ablation without chemotherapy or radiotherapy from 2004 to 2014. High-volume centers (HVCs) were defined as the top 95th percentile of facilities by number of procedures performed. Overall survival (OS) was estimated with the Kaplan-Meier method, and comparisons between survival curves were performed with the log-rank test. Propensity score-matched cohort analysis was performed. P values less than .05 were considered statistically significant. RESULTS: In the final cohort, 967 cases were included. Estimated median survival and follow-up were 33.1 and 62.5 months, respectively. Of 305 facilities, 15 were determined to be HVCs, treating 13 or more patients from 2004 to 2014. A total of 335 cases (34.6%) were treated at HVCs. On multivariate Cox regression analysis, treatment at an HVC was independently associated with improved OS (hazard ratio [HR] = 0.766; P = .006). After propensity score adjustment, 1-, 3-, and 5-year OS was 89.8%, 51.2%, and 27.7%, respectively, for patients treated at HVCs, compared to 85.2%, 41.5%, and 19.6%, respectively, for patients treated at non-HVCs (P = .015). Increasing age (HR = 1.012; P = .013) and higher T-classification (HR = 1.392; P < .001) were independently associated with worse OS. CONCLUSION: Patients with early-stage NSCLC treated with RF ablation at HVCs experienced a significant increase in OS, suggesting regionalization of lung cancer management as a means of improving outcomes. PMID- 30293736 TI - Shoulder loading reliability in seated able-bodied subjects. AB - Shoulder performance and sensorimotor control assessments help to identify shoulder instabilities and document the rehabilitation progress. Testing seated subjects in a position of hand prehension requires less controlled adjustments to maintain body balance in a clinically relevant situation. The objective of this work was to determine the test-retest repeatability of a novel shoulder stability test in seated subjects with the ipsi-lateral hand in prehension during four arm loading conditions. Able-bodied subjects were seated on a rigid chair fixed to a force plate. A horizontally and posteriorly directed force was applied to the hand for four 4 loading conditions ranging from 0 to 3 kg. Ten postural balance parameters were calculated from the center of pressure displacements and its corresponding free moments. Intra-class correlation coefficients were calculated for three consecutive trials and for four loading conditions. Generally, the intra-class correlations values increased gradually with the load and varied from 0.727 to 0.948. Tz values increased non-linearly with the applied load. The test retest reliability of a new shoulder stability test in seated able-bodied subjects was high with sufficient loading (3 kg) and 3 trials. PMID- 30293737 TI - Vacuum pretreatment coupled to ultrasound assisted osmotic dehydration as a novel method for garlic slices dehydration. AB - This study investigated the effects of multi-frequency mode ultrasound and vacuum technology on the water loss (WL) of garlic slices during osmotic dehydration (OD), and their effects on the microstructure of garlic. A new method of OD for garlic slices was proposed - Vacuum pretreatment coupled to ultrasound assisted osmotic dehydration (VUOD). The results indicated that the WL of the garlic slices treated with VUOD (21.12%) was significantly (p < 0.05) higher than slices treated with normally OD (NOD) (10.67%), vacuum pretreatment OD (VOD) (14.18%), and multi-frequency mode ultrasound assisted OD (UOD) (11.20-13.56%). A mass transfer mechanism of VUOD was proposed. Low-field nuclear magnetic resonance results quantified the moisture migration in the vacuole, cytoplasm and intercellular space, and the cell wall of garlic cells. The quality properties (allicin content, surface color change and firmness) of VUOD treated garlic slices are predominately better than NOD, VOD and UOD treated samples.

AB - MoO3 nanoparticles were obtained using Sesbania sesban. Novel Schiff base ligand and its nanocomplex of copper were synthesized under ultrasonic irradiation. First MoO3/Copper Schiff base complex nanocomposite (NMCS) based on this natural plant was prepared and characterized by TEM, SEM, AFM, FT-IR, TGA, EDAX and elemental analysis. Then atom-efficient and selective oxidation of alcohols using hydrogen peroxide catalyzed by NMCS bio-nanocomposite under ultrasonic irradiation was reported. Structurally diverse set of alcohols was transformed into desired aldehyde and ketone products with high conversion and excellent selectivity under solvent free conditions. Products were isolated easily from green media, and the catalyst could be reused six times without any appreciable decrease in catalytic activity and selectivity. PMID- 30293739 TI - The ultrasound thermal cracking for the tar-sand bitumen. AB - The influence of ultrasonic irradiation on the tar-sand bitumen in the process of thermal cracking with an inert atmosphere was investigated thoroughly. The product distribution and coke characteristic produced by the conventional thermal cracking (CTC) and ultrasound thermal cracking (UTC) were invested at the following condition: ultrasound frequency 20 kHz, ultrasonic power 2000 W, reaction time 2 h, reaction temperature from 400 to 440 degrees C. The result of the liquid products distribution indicated that UTC can significantly increase gasoline yield and diesel yield, and dramatically reduce VGO (Vacuum Gas Oil) yield and residuum (greater than 500 degrees C) yield. The analysis of gas products showed that there were no significant differences for the gas distribution between the two reactions (methods), indicating that reaction of UTC still conformed to a radical chain mechanism, but the ratio of olefin/paraffin was greatly reduced in the process of UTC, which was attributed to the hydrogen transfer reaction promoted by ultrasound. The result of the analysis by SEM, FT IR, Raman, XRD and Zeta potential demonstrated that there was a significant difference for the morphology of cokes produced by the two methods. Mesocarbon microbeads (MCMB) was discovered in the process of UTC, which should be due to that the polymerization of the free macro-radicals produced from PAHs (Polycyclic Aromatic Hydrocarbons) promoted by ultrasonic cavitation. In addition, it can be inferred that the viscosity of the second liquid phase was reduced by ultrasonic mechanical function through the breakage of the stack of asphaltene molecules cross-linked by van der Waals force. According to the mesophase theory, the ultrasound irradiation promoted the formation of the second liquid phase, extended its existence time and reduced its viscosity, resulting in the formation of MCMB controlled by the surface tension during the process of UTC.

These results highlight notable practice differences. PMID- 30293741 TI - Factors influencing seasonal influenza vaccination uptake among health care workers in an adult tertiary care hospital in Singapore: A cross-sectional survey. AB - BACKGROUND: This study aimed to evaluate the factors influencing seasonal influenza vaccination uptake among different health care professional groups. METHODS: A single-center, cross-sectional survey using a standardized anonymous, self-administered questionnaire to assess knowledge, attitudes, and uptake of seasonal influenza vaccination was used. Associations between respective health care groups and vaccination acceptance were then assessed. RESULTS: In total, 3,873 health care workers completed the questionnaire. Of these, 7% were administrative staff, 17% were allied health staff, 7% were ancillary staff, 11% were medical staff, and 58% were nursing staff. The overall vaccination rate for the Southern Hemisphere 2015 influenza season was 82%. In a multivariate logistic regression model, after controlling for gender and presence of chronic disease, associated factors for accepting influenza vaccination were age, education level of bachelor degree or higher, preference for vaccination provided by mobile teams, having 1-50 patient contacts per week, and belief in the potential severity of influenza and vaccine safety (P < .05). In contrast, factors negatively associated with vaccination acceptance included being a medical staff member or allied health staff member, living with family members under the age of 16, fear of adverse reactions, and disbelief in vaccination effectiveness (P < .05). CONCLUSIONS: Although vaccine coverage in Singapore has been high, our findings provide guidance for the development of strategies to further improve vaccine coverage among different groups of health care workers.

PMID- 30293743 TI - Hands washing glove use, and avoiding recontamination before aseptic procedures at birth: A multicenter time-and-motion study conducted in Zanzibar. AB - BACKGROUND: Our primary objective was to assess hand hygiene (HH) compliance before aseptic procedures among birth attendants in the 10 highest-volume facilities in Zanzibar. We also examined the extent to which recontamination contributes to poor HH. Recording exact recontamination occurrences is not possible using the existing World Health Organization HH audit tool. METHODS: In this time-and-motion study, 3 trained coders used WOMBATv2 software to record the hand actions of all birth attendants present in the study sites. The percentage compliance and 95% confidence intervals (CIs) for individual behaviors (hand washing/rubbing, avoiding recontamination and glove use) and for behavioral sequences during labor and delivery were calculated. RESULTS: We observed 104 birth attendants and 781 HH opportunities before aseptic procedures. Compliance with hand rubbing/washing was 24.6% (95% CI, 21.6-27.8). Only 9.6% (95% CI, 7.6 11.9) of birth attendants also donned gloves and avoided recontamination. Half of the time when rubbing/washing or glove donning was performed, hands were recontaminated prior to the aseptic procedure. CONCLUSIONS: In this study, HH compliance by birth attendants before aseptic procedures was poor. To our knowledge, this is the first study in a low- to middle-income country to show the large contribution to poor HH compliance from hand and glove recontamination before the procedure. Recontamination is an important driver of infection risk from poor HH. It should be understood for the purposes of improvement and therefore included in HH monitoring and interventions. PMID- 30293744 TI - Oral caffeine administered during late gestation increases gestation length and piglet temperature in naturally farrowing sows. AB - Selection of sows for large litter size has adverse consequences including lesser and more variable birth weights, reduced piglet viability and greater peri- and post-natal piglet mortality. One approach to improve survival might be to feed caffeine to the sow, which improves piglet viability after induced farrowing, but has not been evaluated in sows which farrow naturally. Large White x Landrace sows were fed 0 (CON: n = 30) or 6 g/day caffeine (CAF: n = 34) with their daily feed from 3 days before expected parturition until farrowing. Numbers of piglets born alive and stillborn, as well as piglet vitality and meconium staining score were recorded at birth. Piglet rectal temperature was measured at 3 and 24 h and piglet survival was recorded through lactation. Compared with CON animals, sows of the CAF group had longer gestations (CON: 115.6 +/- 0.3 days; CAF: 116.6 +/- 0.3 days, P = 0.01) and piglets of CAF sows had greater rectal temperatures 3 h after birth (CON: 37.6 +/- 0.2 degrees C, CAF 38.0 +/- 0.2 degrees C, P<0.05). Although there was no difference in the stillborn numbers per litter fewer CAF sows delivered stillborn piglets when compared to CON sows (CON: 43.3%, CAF: 20.6%, P = 0.05). Piglet survival to day 18 of lactation was not altered by treatment (CON: 90.4 +/- 3.2%, CAF: 92.0 +/- 2.4%, P>0.05). The current data suggest that maternal supplementation with caffeine is a promising treatment to prevent premature farrowing and increase piglet temperature at birth, and may decrease the incidence of litters with stillborn piglets.

PMID- 30293747 TI - Extracellular DAMPs in Plants and Mammals: Immunity, Tissue Damage and Repair. AB - Innate immune receptors, well known mediators of response to non-self-molecules and inflammation, also act as mediators of immunity triggered by 'damage associated molecular patterns' (DAMPs). Pathogen-associated molecular patterns (PAMPs) cause inflammation in mammals and a rapid immune response in plants, while DAMPs trigger more complex responses, including immunity, tissue maintenance and repair. DAMPs, their receptors and downstream transduction mechanisms are often conserved within a kingdom or, due to convergent evolution, are similar across the kingdoms of life. Herein, we describe the dynamics and functionality of specific extracellular DAMP classes and their receptors in immunity, inflammation and repair of tissue damage in plants and mammals. PMID- 30293748 TI - Comparison of the clinical effectiveness of Bone Morphogenic Protein (BMP) -2 and -7 in the adjunct treatment of lower limb nonunions. AB - BACKGROUND: Substantial evidence exists demonstrating the individual effectiveness of both rhBMP-2 and -7 in the treatment of nonunions, data comparing the clinical effectiveness of adjunct rhBMP-2 and -7 remains scarce. Therefore, we examined our large single-center case series to compare the clinical effectiveness of both rhBMP-2 and -7 in non-union therapy aiming to answer: - Does a certain type of BMP have an advantageous effect on radiological outcome of applied lower limb non-union therapy? - Does application of a certain type of BMP have an advantageous effect on radiological outcome of infected lower limb nonunions? - Are there any additional risk factors associated with inferior outcome in context with an adjunct BMP treatment? HYPOTHESIS: Both BMPs have the same effect on the radiological outcome of surgically treated lower limb nonunions. PATIENTS AND METHODS: Single-center retrospective database analysis of a case series of patients with lower limb long bone nonunions receiving either a one- or two-stage (Masquelet-) procedure based on the "diamond concept" with application of rhBMP-2 or -7. The "diamond concept" summarizes core factors that need to be present to achieve bone healing. In particular, these factors relate to the optimization of the mechanical (stability) and biological environment (sufficient osteogenic and angiogenic cells, osteoconductive scaffolds and growth factors). All medical data from patients that received surgical treatment between 01/01/2010 and 31/12/2016 were assessed. In total, 356 patients were treated with BMPs and 156 patients 18 years or older with non-union of their tibia or femur having a follow-up of at least 1 year were included. Consolidation in context with type of rhBMP was compared and the influence of relevant risk factors assessed. RESULTS: Consolidation rate was significantly higher in patients treated with rhBMP-2 (rhBMP-2: 42/46 (91%) vs. rhBMP-7: 64/110 (58%); p<0.001). In particular, application of rhBMP-2 increased the likelihood of consolidation for tibial nonunions (OR 32.744; 95%CI: 2.909-368.544; p=0.005) and when used in two-stage therapy (OR 12.095; 95% CI: 2.744-53.314; p=0.001). Furthermore, regression modeling revealed a higher correlation between application of rhBMP-2 and osseous consolidation in infected nonunions (OR 61.062; 95% CI: 2.208 1688.475; p=0.015) than in aseptic nonunions (OR 4.787; 95% CI: 1.321-17.351; p=0.017). Risk factors negatively influencing the outcome of non-union treatment in context with rhBMPs were identified as active smoking (OR 0.357; 95% CI: 0.138 0.927; p=0.024), atrophic nonunion (OR 0.23; 95% CI: 0.061-0.869; p=0.030), higher BMI (OR 0.919; 95% CI: 0.846-0.998; p=0.046) and a larger defect size (OR 0.877; 95% CI: 0.784-0.98; p=0.021). DISCUSSION: Patients who received rhBMP-2 for the treatment of tibial nonunions and as part of the two-stage treatment had a significantly higher rate of healing compared to patients treated with rhBMP-7 regardless of infection.

AB - INTRODUCTION: A reliable scoring system that predicts the walking ability of hip fracture patients would be useful for clinicians. Here we developed a scoring system for hip fracture patients and evaluated its predictive ability. HYPOTHESIS: We hypothesized that age, sex, presence of dementia, walking ability before the injury, fracture type, serum hemoglobin level, serum albumin level and interval in days between admission and surgery would be the predictive factors of the walking ability at discharge. MATERIAL AND METHODS: Data from 409 patients who underwent hip fracture surgery were included. We analyzed factors that affected walking ability and developed a scoring system that predicts the probability of walking unaided or with a cane at discharge. RESULTS: The mean age of the patients was 81.3 years. A total of 164 (40%) patients could walk unaided or with a cane at discharge. Multivariate logistic regression analysis showed that the obstructive factors for the ability to walk unaided or with a cane at discharge were older age (odds ratio [OR]=0.962, p=0.002), dementia (OR=0.126, p<0.001), use of a cane before injury (OR=0.396, p<0.001), trochanteric fracture (OR=0.571, p=0.027) and low serum albumin level (OR=4.15, p<0.001) at admission. The scoring system used the following formula: Score=5-0.04*age+albumin-2(with dementia)- 1(with use of a cane before injury)-1(with trochanteric fracture). The C-statistics for the scoring system was 0.81 (95% confidence interval, 0.77 0.85). DISCUSSION: This newly developed scoring system of information at admission predicted the discharge mobility of hip fracture patients. In addition to the previously known risk factors, serum albumin level at admission was detected as a new predictor for mobility at discharge. LEVEL OF PROOF: IV, retrospective study. PMID- 30293750 TI - Fibular non-union in distraction osteogenesis of the tibia. AB - INTRODUCTION: There is concern regarding potential non-union of the fibula following distraction osteogenesis and if non-union of the fibula leads to poor outcome. HYPOTHESIS: Assess the incidence of fibula non-union in patients undergoing distraction osteogenesis of the tibia and to report the effects on patient outcome. We also describe the management of this complication. MATERIALS AND METHODS: A consecutive series of patients undergoing distraction osteogenesis at a tertiary centre under a single surgeon. The amount of distraction, site of osteotomy, union of the fibula and tibia were recorded. RESULTS: Fifty-eight distraction procedures. Mean age was 37.2, 36 males and 22 females. Mean follow up 23.4 months. 49 (84.5%) achieved fibula union at frame removal, and 9 (15.5%) went on to non-union. Of the fibulas that united, the mean lengthening was 9.25mm. In fibula non-union there was significantly greater lengthening (23.66mm) (p=0.004). Fifty-four (93.1%) of the tibias united following osteotomy and distraction, whilst 4 (6.9%) went onto non-union requiring operative treatment. Of the 4 tibias that did not unite, 3 (75%) also had fibula non-union (p=0.01). Three (33.3%) of the 9 fibulas that did not unite developed symptoms. Two of these required surgery in the form of fibula plating. Both of these patient's symptoms resolved following surgery. DISCUSSION: Fibula non-union is a relatively common complication following osteotomy in distraction osteogenesis. The length of fibula distraction and tibia non-union are significant risk factors. We recommend surgical intervention for those patients who have symptomatic fibula non-unions. LEVEL OF EVIDENCE: IV, case series. PMID- 30293751 TI - Total hip arthroplasty after failed transtrochanteric rotational osteotomy for osteonecrosis of the femoral head: A systematic review and meta-analysis. AB - BACKGROUND: Several studies have reported regarding total hip arthroplasty (THA) for osteonecrosis of the femoral head after failed transtrochanteric rotational osteotomy (TRO). However, to our knowledge, no formal systematic review and meta analysis have been published yet summarizing the clinical results of a THA after failed TRO. Therefore, we conducted a systematic review and meta-analysis of the THA outcomes after failed TRO. We focussed on the issue whether a previous TRO affects the results of subsequent THA, including operative time, operative blood loss, radiological parameters, postoperative complications, and clinical outcomes. METHODS: Literatures published up to January 2018 were searched in the PubMed, Web of Science, and Cochrane Library, and the pooling of data was performed using a RevMan software (version 5.3, Cochrane Collaboration, Oxford, UK). A p-value<0.05 was considered statistically significant. We calculated the mean differences (MD) for continuous data and the odds ratio (OR) for dichotomous data with 95% confidence intervals (CI) for each outcome. Statistical heterogeneity was assessed based on I2 using the standard Chi2. When I2>50%, significant heterogeneity was assumed, and a random-effects model was applied for the meta-analysis. A fixed-effects model was applied in the absence of significant heterogeneity. RESULTS: Five studies were included in this meta analysis. The results showed that operative time was significantly longer in the THA after the TRO than that for the THA without previous osteotomy (I2=92%; MD=31.62; 95% CI: 5.95 to 57.28; p=0.02). Operative blood loss was significantly greater in the THA after the TRO than that in the THA without previous osteotomy (I2=71%; MD=123.30; 95% CI: 22.21 to 224.39; p=0.02). The rate of stem malalignment was significantly higher in the THA after the TRO than that in the THA without previous osteotomy (I2=0%; OR=5.23, 95% CI: 1.95 to 14.06; p=0.001). There was no significant difference in the dislocation rate (I2=0%; OR=2.12; 95% CI: 0.64 to 6.99; p=0.22), and the postoperative Harris hip score at the final follow-up (I2=75%, MD=-0.46, 95% CI: -3.92 to 3.01, p=0.80) between the groups. CONCLUSION: The results demonstrate that, performing the THA after the TRO is technically more demanding than the THA without previous osteotomy. TRO does not affect the clinical results of future THA, and is a sufficient therapeutic alternative in younger patients. LEVEL OF EVIDENCE: III, systematic and meta analysis of case control studies. PMID- 30293752 TI - Mast Cells in Neuroimmune Interactions. AB - A major aspect of the regulatory function of mast cells appears to be their role as intermediaries between the nervous and immune systems. Mast cells are activated by neurotransmitters allowing neural control of innate and adaptive immunity. Conversely, mast cells secrete mediators including neurotransmitters and neurotrophic factors that directly influence nerves, causing acute activation and/or long-lasting changes in excitability and phenotype. While some basic mechanisms underlying mast cell-nerve communication are well-established, the full extent to which this relationship influences health and disease is unclear. Future studies of mast cell-nerve interactions may provide greater understanding of how immune and nervous systems coordinate multiple aspects of homeostatic control, and will potentially offer therapeutic targets in both immune and neurological disorders.

PMID- 30293754 TI - Outcomes of Reduced Intensity Conditioning Allogeneic Hematopoietic Stem Cell Transplantation for Hodgkin Lymphomas: A Retrospective Multicenter Experience by the Rete Ematologica Pugliese (REP). AB - BACKGROUND: Hodgkin lymphoma (HL) is a potentially curable disease, and modern therapy is expected to successfully cure more than 80% of the patients. However, patients progressing after intensive treatments, such as autologous stem cell transplantation (SCT), have a very poor outcome. Allogeneic SCT offers the only strategy with a curative potential for these patients. This study reports a retrospective multicenter experience of the Rete Ematologica Pugliese (REP) over the past 17 years, aiming to define the impact of each patient's disease and transplant-related characteristics on outcomes. PATIENTS AND METHODS: We retrospectively studied 72 patients with HL who received allogeneic SCT from 2000 to 2017. At the time of allogeneic SCT, 33 (46%) patients had chemosensitive disease, and 39 (54%) were chemo-refractory. All patients received reduced intensity conditioning, 50% received grafts from a matched sibling donor, and 50% from a matched-unrelated donor. RESULTS: With a median follow-up of 48 months (range, 3-195 months), 30 patients are alive, and 42 have died. The Kaplan-Meier estimates of overall survival and progression-free survival at 5 years were 35% and 34%, respectively. Following transplantation, 12 (17%) patients died of non relapse mortality at a median of 90 days (range, 1 day-20 months). The causes of death included infection (n = 7), graft-versus-host disease (n = 3), and multi organ failure (n = 2). CONCLUSIONS: Allogeneic SCT results extend survival in selected patients with relapsed/refractory HL, showing low treatment-related mortality. Patients with active disease at the time of allogeneic transplantation have poor outcomes. Allogeneic SCT may be an effective salvage strategy for patients who relapse after an autologous SCT.

PMID- 30293756 TI - What Is the Role of Repeat Aspiration in the Diagnosis of Periprosthetic Hip Infection? AB - BACKGROUND: The American Academy of Orthopedic Surgeons clinical practice guideline currently recommends repeat joint aspiration when workup of periprosthetic joint infection (PJI) reveals conflicting data. This guideline is based on a single study of 31 patients published 25 years ago. We sought to determine the correlation between first and second aspirations and factors that may play a role in variability between them. METHODS: Sixty patients with less than 90 days between aspirations and no intervening surgery were identified at our institution and classified by Musculoskeletal Infection Society (MSIS) criteria as infected, not infected, or not able to determine after both aspirations. Culture results from both aspirations were recorded. The rates of change and correlation in clinical diagnosis and culture results between aspirations were determined. RESULTS: Repeat aspiration changed the diagnosis in 26 cases (43.3%, 95% confidence interval 31.6-55.9, kappa coefficient 0.32, P < .001), and the culture results in 25 cases (41.7%, 95% confidence interval 30.1 54.3, kappa coefficient 0.27, P < .01). Among patients initially MSIS negative, the proportion who changed to MSIS positive was greater for those with a history of prior PJI compared to those without (66.7% vs 0%, P < .05), and the first aspiration mean volume was higher for those changed to MSIS positive compared to those that remained MSIS negative (12.0 vs 3.0 mL, P < .01). Among patients initially MSIS positive, the proportion of patients who changed to MSIS negative was greater for those with a history of adverse local tissue reaction (ALTR) to metal debris compared to patients without suspicion of ALTR (100% vs 7.7%, P < .05). CONCLUSION: Repeat aspiration is particularly useful in patients with conflicting clinical data and prior history of PJI, suspicion of ALTR, or with high clinical suspicion of infection.

PMID- 30293761 TI - The diversity of the proline-rich domain of pneumococcal surface protein A (PspA): Potential relevance to a broad-spectrum vaccine. AB - Pneumococcal surface protein A (PspA) is a surface exposed, highly immunogenic protein of Streptococcus pneumoniae. Its N-terminal alpha-helical domain (alphaHD) elicits protective antibody in humans and animals that can protect mice from fatal infections with pneumococci and can be detected in vitro with opsonophagocytosis assays. The proline-rich domain (PRD) in the center of the PspA sequence can also elicit protection. This study revealed that although the sequence of PRD was diverse, PRD from different pneumococcal isolates contained many shared elements. The inferred amino acid sequences of 123 such PRDs, which were analyzed by assembly and alignment-free (AAF) approaches, formed three PRD groups. Of these sequences, 45 were classified as Group 1, 19 were classified as Group 2, and 59 were classified as Group 3. All Group 3 sequences contained a highly conserved 22-amino acid non-proline block (NPB). A significant polymorphism was observed, however, at a single amino acid position within NPB. Each of the three PRD groups had characteristic patterns of short amino acid repeats, with most of the repeats being found in more than one PRD group. One of these repeats, PKPEQP as well as the NPB were previously shown to elicit protective antibodies in mice. In this study, we found that sera from 12 healthy human adult volunteers contained antibodies to all three PRD groups. This suggested that a PspA-containing vaccine containing carefully selected PRDs and alphaHDs could redundantly cover the known diversity of PspA. Such an approach might reduce the chances of PspA variants escaping a PspA vaccine's immunity.

AB - A candidate hand, foot, and mouth disease vaccine comprising of human enterovirus A71 (EV-A71) virus-like particles (VLPs) was tested in rabbits to evaluate the potential local and systemic effects of this vaccine. The rabbits received more than double the full human dose and one additional dose according to the n + 1 recommended scheme. The three doses were given mixed with Alhydrogel adjuvant as intramuscular (IM) injections. Vaccinations were well-tolerated, with no indication of overt toxicity in any parameter observed. An EV-A71 specific immune response in the form of antibodies that specifically reacted with the virus capsid proteins VP1 and VP0, the complete VLP, and EV-A71 viruses of different subgenotypes to that of the vaccine could be demonstrated. A boosting effect in the form of higher EV-A71 specific antibody titers was observed after the subsequent doses, and these enhanced titers were shown to be statistically significant in one-way ANOVA analyses. Fortnightly intramuscular administration of EV-A71 VLP vaccine did not result in any test article-related changes in immunotoxicity as defined by increased serum IL-6, and in general IL-6 concentrations remained below the lower limit of quantitation for the majority of animals throughout the study. Although increased indicators of inflammation at the injection site were observed in animals sacrificed immediately after the last vaccination, these largely reversed at the end of the recovery phase. No findings suggestive of systemic or delayed toxicity were recorded in this independently conducted study. In conclusion, repeated IM administration of the EV-A71 VLP vaccine were locally and systemically well-tolerated in rabbits and immunogenic, supporting the clinical development of the vaccine. PMID- 30293763 TI - Co-delivery of amphipol-conjugated adjuvant with antigen, and adjuvant combinations, enhance immune protection elicited by a membrane protein-based vaccine against a mucosal challenge with Chlamydia. AB - INTRODUCTION: Chlamydial infections are spread worldwide and a vaccine is needed to control this pathogen. The goals of this study were to determine if the delivery of an adjuvant associated to the antigen, via a derivatized amphipol, and adjuvant combinations improve vaccine protection. METHODS: A novel approach, trapping the Chlamydia muridarum (Cm) native MOMP (nMOMP) with amphipols (A8-35), bearing a covalently conjugated peptide (EP67), was used. Adjuvants incorporated were: EP67 either conjugated to A8-35, which was used to trap nMOMP (nMOMP/EP67 A8-35), or free as a control, added to nMOMP/A8-35 complexes (nMOMP/A8-35+EP67); Montanide ISA 720 to enhance humoral responses, and CpG-1826 to elicit robust cell-mediated immunity (CMI). BALB/c mice were immunized by mucosal and systemic routes. Intranasal immunization with live Cm was used as positive control and three negative controls were included. Mice were challenged intranasally with Cm and changes in body weight, lungs weight and number of Cm-inclusion forming units (IFU) recovered from the lungs were evaluated to establish protection. To assess local responses levels of IFN- gamma and Cm-specific IgA were determined in lungs' supernatants. RESULTS: Structural assays demonstrated that nMOMP secondary structure and thermal stability were maintained when A8-35 was covalently modified. Mice vaccinated with nMOMP/EP67-A8-35 were better protected than animals immunized with nMOMP/A8-35+EP67. Addition of Montanide enhanced Th2 responses and improved protection. Including CpG-1826 further broadened, intensified and switched to Th1-biased immune responses. With delivery of nMOMP and the three adjuvants, as determined by changes in body weight, lungs weight and number of IFU recovered from lungs, protection at 10 days post-challenge was equivalent to that induced by immunization with live Cm. CONCLUSIONS: Covalent association of EP67 to A8-35, used to keep nMOMP water-soluble, improves protection over that conferred by free EP67. Adjuvant combinations including EP67+Montanide+CpG-1826, by broadening and intensifying cellular and humoral immune responses, further enhanced protection. PMID- 30293764 TI - Mitigating bias in observational vaccine effectiveness studies using simulated comparator populations: Application to rotavirus vaccination in the UK. AB - BACKGROUND: Measuring vaccine effectiveness (VE) relies on the use of observational study designs. However, achieving robust estimates of direct and indirect VE is frequently compromised by bias, particularly when using syndromic diagnoses of low-specificity. METHODS: In order to mitigate confounding between the measured outcome and vaccine uptake, we developed a method to balance comparator populations using individual-level propensity scoring derived from the vaccine-exposed population, and applied it to the unexposed comparator population. Indirect VE was estimated by comparing the unvaccinated vaccine exposed group with a propensity score-simulated unvaccinated, unexposed group. Direct VE was derived by removing indirect VE from the overall VE. We applied this method to an evaluation of the effectiveness of infant rotavirus vaccination in the UK. Using a general practice cohort of 45,259 live births between May 2010 and December 2015, we calculated indirect and direct VE against consultations for acute gastroenteritis using conventional and vaccination-propensity adjustment comparator populations. RESULTS: The overall VE during the rotavirus-season (January-May) calculated using mixed-effects Cox regression was 30% [95% confidence intervals (95% CI: 25,35%)]. Use of conventional comparator populations resulted in implausible VE estimates -14% (95% CI: -41,7%) for direct and 29% (95% CI: 14,42%) for indirect effects. Applying our alternative method, direct VE was 26% (95% CI: 1,45%) and indirect VE was 8% (95% CI: -19,29%). CONCLUSIONS: Estimating VE using propensity score simulated comparator populations, particularly for studies using routine health data with syndromic, low-specificity endpoints will aid accurate measurement of the broader public health impact of a vaccine programme. PMID- 30293765 TI - Cost-effectiveness analysis of maternal immunisation against group B Streptococcus (GBS) disease: A modelling study. AB - BACKGROUND: There is a considerable global burden of invasive group B streptococcal (GBS) disease. Vaccines are being developed for use in pregnant women to offer protection to neonates. OBJECTIVE: To estimate the potential impact and cost-effectiveness of maternal immunisation against neonatal and maternal invasive GBS disease in the UK. METHODS: We developed a decision-tree model encompassing GBS-related events in infants and mothers, following a birth cohort with a time horizon equivalent to average life expectancy (81 years). We parameterised the model using contemporary data from disease surveillance and outcomes in GBS survivors. Costs were taken from NHS sources and research studies. Maternal immunisation in combination with risk-based intrapartum antibiotic prophylaxis (IAP) was compared to the current standard practice of risk-based IAP alone from an NHS and Personal Social Services (health-provider) perspective. We estimated the cases averted and cost per QALY gained through vaccination. One-way sensitivity analysis, scenario analysis and probabilistic sensitivity analysis were performed. RESULTS: An effective maternal immunisation programme could substantially reduce the burden of GBS disease. The deterministic analysis estimated the threshold cost-effective price for a GBS vaccine to be L54 per dose at L20,000/QALY (L71 per dose at L30,000/QALY). Results were most sensitive to assumptions on disease incidence, sequelae rate and vaccine efficacy. Probabilistic analysis showed 90.66% of iterations fell under the L30,000 threshold at a vaccine price of L55. Inclusion of modest prevention of stillbirths and/or, preterm births, carer health impacts, maternal GBS deaths and 1.5% discounting improved cost-effectiveness compared to the base case. Lowering vaccine strain coverage made the vaccine less cost-effective. A key limitation is that the properties of the final GBS vaccine are unknown. CONCLUSIONS: Maternal GBS immunisation is expected to be cost-effective, even at a relatively high vaccine price.

PMID- 30293769 TI - Baseline and on-statin treatment lipoprotein(a) levels for prediction of cardiovascular events: individual patient-data meta-analysis of statin outcome trials. AB - BACKGROUND: Elevated lipoprotein(a) is a genetic risk factor for cardiovascular disease in general population studies. However, its contribution to risk for cardiovascular events in patients with established cardiovascular disease or on statin therapy is uncertain. METHODS: Patient-level data from seven randomised, placebo-controlled, statin outcomes trials were collated and harmonised to calculate hazard ratios (HRs) for cardiovascular events, defined as fatal or non fatal coronary heart disease, stroke, or revascularisation procedures. HRs for cardiovascular events were estimated within each trial across predefined lipoprotein(a) groups (15 to <30 mg/dL, 30 to <50 mg/dL, and >=50 mg/dL, vs <15 mg/dL), before pooling estimates using multivariate random-effects meta-analysis. FINDINGS: Analyses included data for 29 069 patients with repeat lipoprotein(a) measurements (mean age 62 years [SD 8]; 8064 [28%] women; 5751 events during 95 576 person-years at risk). Initiation of statin therapy reduced LDL cholesterol (mean change -39% [95% CI -43 to -35]) without a significant change in lipoprotein(a). Associations of baseline and on-statin treatment lipoprotein(a) with cardiovascular disease risk were approximately linear, with increased risk at lipoprotein(a) values of 30 mg/dL or greater for baseline lipoprotein(a) and 50 mg/dL or greater for on-statin lipoprotein(a). For baseline lipoprotein(a), HRs adjusted for age and sex (vs <15 mg/dL) were 1.04 (95% CI 0.91-1.18) for 15 mg/dL to less than 30 mg/dL, 1.11 (1.00-1.22) for 30 mg/dL to less than 50 mg/dL, and 1.31 (1.08-1.58) for 50 mg/dL or higher; respective HRs for on-statin lipoprotein(a) were 0.94 (0.81-1.10), 1.06 (0.94-1.21), and 1.43 (1.15-1.76). HRs were almost identical after further adjustment for previous cardiovascular disease, diabetes, smoking, systolic blood pressure, LDL cholesterol, and HDL cholesterol. The association of on-statin lipoprotein(a) with cardiovascular disease risk was stronger than for on-placebo lipoprotein(a) (interaction p=0.010) and was more pronounced at younger ages (interaction p=0.008) without effect-modification by any other patient-level or study-level characteristics. INTERPRETATION: In this individual-patient data meta-analysis of statin-treated patients, elevated baseline and on-statin lipoprotein(a) showed an independent approximately linear relation with cardiovascular disease risk. This study provides a rationale for testing the lipoprotein(a) lowering hypothesis in cardiovascular disease outcomes trials. FUNDING: Novartis Pharma AG. PMID- 30293770 TI - Efficacy and safety of LY3298176, a novel dual GIP and GLP-1 receptor agonist, in patients with type 2 diabetes: a randomised, placebo-controlled and active comparator-controlled phase 2 trial. AB - BACKGROUND: LY3298176 is a novel dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist that is being developed for the treatment of type 2 diabetes. We aimed to examine the efficacy and safety of co-stimulation of the GLP-1 and GIP receptors with LY3298176 compared with placebo or selective stimulation of GLP-1 receptors with dulaglutide in patients with poorly controlled type 2 diabetes. METHODS: In this double-blind, randomised, phase 2 study, patients with type 2 diabetes were randomly assigned (1:1:1:1:1:1) to receive either once-weekly subcutaneous LY3298176 (1 mg, 5 mg, 10 mg, or 15 mg), dulaglutide (1.5 mg), or placebo for 26 weeks. Assignment was stratified by baseline glycated haemoglobin A1c (HbA1c), metformin use, and body-mass index (BMI). Eligible participants (aged 18-75) had type 2 diabetes for at least 6 months (HbA1c 7.0-10.5%, inclusive), that was inadequately controlled with diet and exercise alone or with stable metformin therapy, and a BMI of 23-50 kg/m2. The primary efficacy outcome was change in HbA1c from baseline to 26 weeks in the modified intention-to-treat (mITT) population (all patients who received at least one dose of study drug and had at least one postbaseline measurement of any outcome). Secondary endpoints, measured in the mITT on treatment dataset, were change in HbA1c from baseline to 12 weeks; change in mean bodyweight, fasting plasma glucose, waist circumference, total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides, and proportion of patients reaching the HbA1c target (<=6.5% and <7.0%) from baseline to weeks 12 and 26; and proportion of patients with at least 5% and 10% bodyweight loss from baseline to 26 weeks. This study is registered with ClinicalTrials.gov, number NCT03131687. FINDINGS: Between May 24, 2017, and March 28, 2018, 555 participants were assessed for eligibility, of whom 318 were randomly assigned to one of the six treatment groups. Because two participants did not receive treatment, the modified intention-to-treat and safety populations included 316 participants. 258 (81.7%) participants completed 26 weeks of treatment, and 283 (89.6%) completed the study. At baseline, mean age was 57 years (SD 9), BMI was 32.6 kg/m2 (5.9), duration from diagnosis of diabetes was 9 years (6), HbA1c was 8.1% (1.0), 53% of patients were men, and 47% were women. At 26 weeks, the effect of LY3298176 on change in HbA1c was dose-dependent and did not plateau. Mean changes from baseline in HbA1c with LY3298176 were -1.06% for 1 mg, -1.73% for 5 mg, -1.89% for 10 mg, and -1.94% for 15 mg, compared with -0.06% for placebo (posterior mean differences [80% credible set] vs placebo: -1.00% [-1.22 to 0.79] for 1 mg, -1.67% [-1.88 to -1.46] for 5 mg, -1.83% [-2.04 to -1.61] for 10 mg, and -1.89% [-2.11 to -1.67] for 15 mg). Compared with dulaglutide (-1.21%) the posterior mean differences (80% credible set) for change in HbA1c from baseline to 26 weeks with the LY3298176 doses were 0.15% (-0.08 to 0.38) for 1 mg, -0.52% (-0.72 to -0.31) for 5 mg, -0.67% (-0.89 to -0.46) for 10 mg, and 0.73% (-0.95 to -0.52) for 15 mg. At 26 weeks, 33-90% of patients treated with LY3298176 achieved the HbA1c target of less than 7.0% (vs 52% with dulaglutide, 12% with placebo) and 15-82% achieved the HbA1c target of at least 6.5% (vs 39% with dulaglutide, 2% with placebo). Changes in fasting plasma glucose ranged from -0.4 mmol/L to -3.4 mmol/L for LY3298176 (vs 0.9 mmol/L for placebo, -1.2 mmol/L for dulaglutide). Changes in mean bodyweight ranged from -0.9 kg to -11.3 kg for LY3298176 (vs -0.4 kg for placebo, -2.7 kg for dulaglutide). At 26 weeks, 14-71% of those treated with LY3298176 achieved the weight loss target of at least 5% (vs 22% with dulaglutide, 0% with placebo) and 6-39% achieved the weight loss target of at least 10% (vs 9% with dulaglutide, 0% with placebo). Changes in waist circumference ranged from -2.1 cm to -10.2 cm for LY3298176 (vs -1.3 cm for placebo, -2.5 cm for dulaglutide). Changes in total cholesterol ranged from 0.2 mmol/L to -0.3 mmol/L for LY3298176 (vs 0.3 mmol/L for placebo, -0.2 mmol/L for dulaglutide). Changes in HDL or LDL cholesterol did not differ between the LY3298176 and placebo groups. Changes in triglyceride concentration ranged from 0 mmol/L to -0.8 mmol/L for LY3298176 (vs 0.3 mmol/L for placebo, -0.3 mmol/L for dulaglutide). The 12-week outcomes were similar to those at 26 weeks for all secondary outcomes. 13 (4%) of 316 participants across the six treatment groups had 23 serious adverse events in total. Gastrointestinal events (nausea, diarrhoea, and vomiting) were the most common treatment-emergent adverse events. The incidence of gastrointestinal events was dose-related (23.1% for 1 mg LY3298176, 32.7% for 5 mg LY3298176, 51.0% for 10 mg LY3298176, and 66.0% for 15 mg LY3298176, 42.6% for dulaglutide, 9.8% for placebo); most events were mild to moderate in intensity and transient. Decreased appetite was the second most common adverse event (3.8% for 1 mg LY3298176, 20.0% for 5 mg LY3298176, 25.5% for 10 mg LY3298176, 18.9% for 15 mg LY3298176, 5.6% for dulaglutide, 2.0% for placebo). There were no reports of severe hypoglycaemia. One patient in the placebo group died from lung adenocarcinoma stage IV, which was unrelated to study treatment. INTERPRETATION: The dual GIP and GLP-1 receptor agonist, LY3298176, showed significantly better efficacy with regard to glucose control and weight loss than did dulaglutide, with an acceptable safety and tolerability profile. Combined GIP and GLP-1 receptor stimulation might offer a new therapeutic option in the treatment of type 2 diabetes. FUNDING: Eli Lilly and Company.

AB - Dysregulation of extracellular matrix (ECM) deposition and cellular metabolism promotes tumor aggressiveness by sustaining the activity of key growth, invasion, and survival pathways. Yet mechanisms by which biophysical properties of ECM relate to metabolic processes and tumor progression remain undefined. In both cancer cells and carcinoma-associated fibroblasts (CAFs), we found that ECM stiffening mechanoactivates glycolysis and glutamine metabolism and thus coordinates non-essential amino acid flux within the tumor niche. Specifically, we demonstrate a metabolic crosstalk between CAF and cancer cells in which CAF derived aspartate sustains cancer cell proliferation, while cancer cell-derived glutamate balances the redox state of CAFs to promote ECM remodeling. Collectively, our findings link mechanical stimuli to dysregulated tumor metabolism and thereby highlight a new metabolic network within tumors in which diverse fuel sources are used to promote growth and aggressiveness. Furthermore, this study identifies potential metabolic drug targets for therapeutic development in cancer. PMID- 30293774 TI - Preserving Insulin Secretion in Diabetes by Inhibiting VDAC1 Overexpression and Surface Translocation in beta Cells. AB - Type 2 diabetes (T2D) develops after years of prediabetes during which high glucose (glucotoxicity) impairs insulin secretion. We report that the ATP conducting mitochondrial outer membrane voltage-dependent anion channel-1 (VDAC1) is upregulated in islets from T2D and non-diabetic organ donors under glucotoxic conditions. This is caused by a glucotoxicity-induced transcriptional program, triggered during years of prediabetes with suboptimal blood glucose control. Metformin counteracts VDAC1 induction. VDAC1 overexpression causes its mistargeting to the plasma membrane of the insulin-secreting beta cells with loss of the crucial metabolic coupling factor ATP. VDAC1 antibodies and inhibitors prevent ATP loss. Through direct inhibition of VDAC1 conductance, metformin, like specific VDAC1 inhibitors and antibodies, restores the impaired generation of ATP and glucose-stimulated insulin secretion in T2D islets. Treatment of db/db mice with VDAC1 inhibitor prevents hyperglycemia, and maintains normal glucose tolerance and physiological regulation of insulin secretion. Thus, beta cell function is preserved by targeting the novel diabetes executer protein VDAC1. PMID- 30293775 TI - Complement Component C3 Is Highly Expressed in Human Pancreatic Islets and Prevents beta Cell Death via ATG16L1 Interaction and Autophagy Regulation. AB - We show here that human pancreatic islets highly express C3, which is both secreted and present in the cytosol. Within isolated human islets, C3 expression correlates with type 2 diabetes (T2D) donor status, HbA1c, and inflammation. Islet C3 expression is also upregulated in several rodent diabetes models. C3 interacts with ATG16L1, which is essential for autophagy. Autophagy relieves cellular stresses faced by beta cells during T2D and maintains cellular homeostasis. C3 knockout in clonal beta cells impaired autophagy and led to increased apoptosis after exposure of cells to palmitic acid and IAPP. In the absence of C3, autophagosomes do not undergo fusion with lysosomes. Thus, C3 may be upregulated in islets during T2D as a cytoprotective factor against beta cell dysfunction caused by impaired autophagy. Therefore, we revealed a previously undescribed intracellular function for C3, connecting the complement system directly to autophagy, with a broad potential importance in other diseases and cell types.

PMID- 30293776 TI - The Itaconate Pathway Is a Central Regulatory Node Linking Innate Immune Tolerance and Trained Immunity. AB - Sepsis involves simultaneous hyperactivation of the immune system and immune paralysis, leading to both organ dysfunction and increased susceptibility to secondary infections. Acute activation of myeloid cells induced itaconate synthesis, which subsequently mediated innate immune tolerance in human monocytes. In contrast, induction of trained immunity by beta-glucan counteracted tolerance induced in a model of human endotoxemia by inhibiting the expression of immune-responsive gene 1 (IRG1), the enzyme that controls itaconate synthesis. beta-Glucan also increased the expression of succinate dehydrogenase (SDH), contributing to the integrity of the TCA cycle and leading to an enhanced innate immune response after secondary stimulation. The role of itaconate was further validated by IRG1 and SDH polymorphisms that modulate induction of tolerance and trained immunity in human monocytes. These data demonstrate the importance of the IRG1-itaconate-SDH axis in the development of immune tolerance and training and highlight the potential of beta-glucan-induced trained immunity to revert immunoparalysis. PMID- 30293778 TI - Associations between Race/Ethnicity, Uterine Fibroids, and Minimally Invasive Hysterectomy in the VA Healthcare System. AB - BACKGROUND: In the general population, Black and Latina women are less likely to undergo minimally invasive hysterectomy than White women, which may be related to racial/ethnic variation in fibroid prevalence and characteristics. Whether similar differences exist in the Department of Veterans Affairs Healthcare System (VA) is unknown. METHODS: Using VA clinical and administrative data, we identified all women veterans undergoing hysterectomy for benign indications in fiscal years 2012-2014. We identified hysterectomy route (laparoscopic with/without robot-assist, vaginal, abdominal) by International Classification of Diseases, 9th edition, codes. We used multinomial logistic regression to estimate associations of race/ethnicity with hysterectomy route and tested whether associations varied by fibroid diagnosis using an interaction term. Models adjusted for age, income, body mass index, gynecologic diagnoses, medical comorbidities, whether procedure was performed or paid for by VA, geographic region, and fiscal year. RESULTS: Among 2,744 identified hysterectomies, 53% were abdominal, 29% laparoscopic, and 18% vaginal. In multinomial models, racial/ethnic differences were present among veterans with but not without fibroid diagnoses (p value for interaction < .001). Among veterans with fibroids, Black veterans were less likely than White veterans to have minimally invasive hysterectomy (laparoscopic vs. abdominal relative risk ratio [RRR], 0.52; 95% CI, 0.38-0.72; vaginal vs. abdominal RRR, 0.58; 95% CI, 0.43-0.73). Latina veterans were as likely as White veterans to have laparoscopic as abdominal hysterectomy (RRR, 1.34; 95% CI, 0.87-2.07) and less likely to have vaginal than abdominal hysterectomy (RRR, 0.32; 95% CI, 0.15-0.69). CONCLUSIONS: Receipt of minimally invasive hysterectomy among women veterans with fibroids varied by race/ethnicity. Further investigation of the underlying mechanisms and potential interventions to increase minimally invasive hysterectomy among minority women veterans is needed. PMID- 30293779 TI - Validation of a Holographic Display for Quantification of Mitral Annular Dynamics by Three-Dimensional Echocardiography. AB - BACKGROUND: Three-dimensional (3D) echocardiography with multiplanar reconstruction (MPR) is used clinically to quantify the mitral annulus. MPR images are, however, presented on a two-dimensional screen, calling into question their accuracy. An alternative to MPR is an autostereoscopic holographic display that enables in-depth visualization of 3D echocardiographic data without the need for special glasses. The aim of this study was to validate an autostereoscopic display using sonomicrometry as a gold standard. METHODS: In 11 anesthetized open chest pigs, sonomicrometric crystals were placed along the mitral annulus and near the left ventricular apex. High-fidelity catheters measured left atrial and ventricular pressures. Adjustments of pre- and afterload were done by constriction of the inferior vena cava and the ascending aorta, respectively. Three-dimensional epicardial echocardiography was obtained from an apical view and converted to the autostereoscopic display. A 3D virtual semitransparent annular surface (VSAS) was generated to measure commissure width (CW), septal lateral length, area of the mitral annular surface, nonplanarity angle, and the annular height-to-commissure width ratio in mid-systole and late diastole. RESULTS: Mitral annular measurements from the 3D VSAS derived from the 3D echocardiographic images and autostereoscopic display correlated well with sonomicrometry over a range of loading conditions: CW length (r = 0.98, P < .00001), septal-lateral length (r = 0.98, P < .00001), annular surface area (r = 0.93, P < .001), nonplanarity angle (r = 0.87, P < .001), and annular height-to commissure width ratio (r = 0.85, P < .01). The 3D VSAS showed better agreement with the sonomicrometric measurements compared with MPR. CONCLUSIONS: Mitral annular measurements using 3D VSAS correlate well with sonomicrometry over a range of loading conditions and may represent a powerful tool for noninvasive quantification of mitral annular dynamics.

Here, we demonstrate that a CRISPR-guided cytidine deaminase (i.e., targeted-AID mediated mutagenesis [TAM]) can efficiently modulate various forms of mRNA splicing. By converting invariant guanines to adenines at either 5' or 3' splice sites (SS), TAM induces exon skipping, activation of alternative SS, switching between mutually exclusive exons, or targeted intron retention. Conversely, TAM promotes downstream exon inclusion by mutating cytidines into thymines at the polypyrimidine tract. Applying this approach, we genetically restored the open reading frame and dystrophin function of a mutant DMD gene in patient-derived induced pluripotent stem cells (iPSCs). Thus, the CRISPR-guided cytidine deaminase provides a versatile genetic platform to modulate RNA splicing and to correct mutations associated with aberrant splicing in human diseases. PMID- 30293781 TI - Regulation of the Hippo Pathway by Phosphatidic Acid-Mediated Lipid-Protein Interaction. AB - The Hippo pathway plays a crucial role in organ size control and tumor suppression, but its precise regulation is not fully understood. In this study, we discovered that phosphatidic acid (PA)-related lipid signaling is a key regulator of the Hippo pathway. Supplementing PA in various Hippo-activating conditions activates YAP. This PA-related lipid signaling is involved in Rho mediated YAP activation. Mechanistically, PA directly interacts with Hippo components LATS and NF2 to disrupt LATS-MOB1 complex formation and NF2-mediated LATS membrane translocation and activation, respectively. Inhibition of phospholipase D (PLD)-dependent PA production suppresses YAP oncogenic activities. PLD1 is highly expressed in breast cancer and positively correlates with YAP activation, suggesting their pathological relevance in breast cancer development. Taken together, our study not only reveals a role of PLD-PA lipid signaling in regulating the Hippo pathway but also indicates that the PLD-PA-YAP axis is a potential therapeutic target for cancer treatment. PMID- 30293780 TI - Genomic Copy-Number Loss Is Rescued by Self-Limiting Production of DNA Circles. AB - Copy-number changes generate phenotypic variability in health and disease. Whether organisms protect against copy-number changes is largely unknown. Here, we show that Saccharomyces cerevisiae monitors the copy number of its ribosomal DNA (rDNA) and rapidly responds to copy-number loss with the clonal amplification of extrachromosomal rDNA circles (ERCs) from chromosomal repeats. ERC formation is replicative, separable from repeat loss, and reaches a dynamic steady state that responds to the addition of exogenous rDNA copies. ERC levels are also modulated by RNAPI activity and diet, suggesting that rDNA copy number is calibrated against the cellular demand for rRNA. Last, we show that ERCs reinsert into the genome in a dosage-dependent manner, indicating that they provide a reservoir for ultimately increasing rDNA array length. Our results reveal a DNA based mechanism for rapidly restoring copy number in response to catastrophic gene loss that shares fundamental features with unscheduled copy-number amplifications in cancer cells. PMID- 30293784 TI - The Proto-oncogene c-Kit Inhibits Tumor Growth by Behaving as a Dependence Receptor. AB - c-Kit is a classic proto-oncogene either mutated or upregulated in cancer cells, and this leads to its constitutive kinase activation and, thus, to uncontrolled proliferation. Although the pro-oncogenic role of c-Kit is of no doubt, some observations do not fit well with c-Kit solely as a tumor-promoting moiety. We show here that c-Kit actively triggers cell death in various cancer cell lines unless engaged by its ligand stem cell factor (SCF). This pro-death activity is enhanced when the kinase activation of c-Kit is silenced and is due to c-Kit intracellular cleavage by caspase-like protease at D816. Moreover, in vivo, overexpression of a c-Kit kinase-dead mutant inhibits tumor growth, and this intrinsic c-Kit tumor-suppressive activity is dependent on the D816 cleavage. Thus, c-Kit acts both as a proto-oncogene via its kinase activity and as a tumor suppressor via its dependence receptor activity. PMID- 30293783 TI - ZNF598 Is a Quality Control Sensor of Collided Ribosomes. AB - Aberrantly slow translation elicits quality control pathways initiated by the ubiquitin ligase ZNF598. How ZNF598 discriminates physiologic from pathologic translation complexes and ubiquitinates stalled ribosomes selectively is unclear. Here, we find that the minimal unit engaged by ZNF598 is the collided di ribosome, a molecular species that arises when a trailing ribosome encounters a slower leading ribosome. The collided di-ribosome structure reveals an extensive 40S-40S interface in which the ubiquitination targets of ZNF598 reside. The paucity of 60S interactions allows for different ribosome rotation states, explaining why ZNF598 recognition is indifferent to how the leading ribosome has stalled. The use of ribosome collisions as a proxy for stalling allows the degree of tolerable slowdown to be tuned by the initiation rate on that mRNA; hence, the threshold for triggering quality control is substrate specific. These findings illustrate how higher-order ribosome architecture can be exploited by cellular factors to monitor translation status. PMID- 30293787 TI - Worsening alopecia in an elderly woman. PMID- 30293786 TI - Genome-wide Identification of Structure-Forming Repeats as Principal Sites of Fork Collapse upon ATR Inhibition. AB - DNA polymerase stalling activates the ATR checkpoint kinase, which in turn suppresses fork collapse and breakage. Herein, we describe use of ATR inhibition (ATRi) as a means to identify genomic sites of problematic DNA replication in murine and human cells. Over 500 high-resolution ATR-dependent sites were ascertained using two distinct methods: replication protein A (RPA)-chromatin immunoprecipitation (ChIP) and breaks identified by TdT labeling (BrITL). The genomic feature most strongly associated with ATR dependence was repetitive DNA that exhibited high structure-forming potential. Repeats most reliant on ATR for stability included structure-forming microsatellites, inverted retroelement repeats, and quasi-palindromic AT-rich repeats. Notably, these distinct categories of repeats differed in the structures they formed and their ability to stimulate RPA accumulation and breakage, implying that the causes and character of replication fork collapse under ATR inhibition can vary in a DNA-structure specific manner. Collectively, these studies identify key sources of endogenous replication stress that rely on ATR for stability. PMID- 30293788 TI - Bilateral hand edema: simply nothing or nothing simple?

PMID- 30293771 TI - Effect of lorcaserin on prevention and remission of type 2 diabetes in overweight and obese patients (CAMELLIA-TIMI 61): a randomised, placebo-controlled trial. AB - BACKGROUND: There is a direct relationship between bodyweight and risk of diabetes. Lorcaserin, a selective serotonin 2C receptor agonist that suppresses appetite, has been shown to facilitate sustained weight loss in obese or overweight patients. We aimed to evaluate the long-term effects of lorcaserin on diabetes prevention and remission. METHODS: In this randomised, double-blind, placebo-controlled trial done in eight countries, we recruited overweight or obese patients (body-mass index >=27 kg/m2) with or at high risk for atherosclerotic vascular disease. Eligible patients were aged 40 years or older; patients at high risk for atherosclerotic vascular disease had to be aged 50 years or older with diabetes and at least one other risk factor. Patients were randomly assigned to receive either lorcaserin (10 mg twice daily) or matching placebo. Additionally, all patients had access to a standardised weight management programme based on lifestyle modification. The prespecified primary metabolic efficacy endpoint of time to incident diabetes was assessed in patients with prediabetes at baseline. The prespecified secondary outcomes for efficacy were incident diabetes in all patients without diabetes, achievement of normoglycaemia in patients with prediabetes, and change in glycated haemoglobin (HbA1c) in patients with diabetes. Hypoglycaemia was a prespecified safety outcome. Analysis was by intention to treat, using Cox proportional hazard models for time-to-event analyses. This trial is registered with ClinicalTrials.gov, number NCT02019264. FINDINGS: Between Feb 7, 2014, and Nov 20, 2015, 12 000 patients were randomly assigned to lorcaserin or placebo (6000 patients in each group) and followed up for a median of 3.3 years (IQR 3.0-3.5). At baseline, 6816 patients (56.8%) had diabetes, 3991 (33.3%) prediabetes, and 1193 (9.9%) normoglycaemia. At 1 year, patients treated with lorcaserin had a net weight loss beyond placebo of 2.6 kg (95% CI 2.3-2.9) for those with diabetes, 2.8 kg (2.5 3.2) for those with prediabetes, and 3.3 kg (2.6-4.0) for those with normoglycaemia (p<0.0001 for all analyses). Lorcaserin reduced the risk of incident diabetes by 19% in patients with prediabetes (172 [8.5%] of 2015 vs 204 [10.3%] of 1976; hazard ratio 0.81, 95% CI 0.66-0.99; p=0.038) and by 23% in patients without diabetes (174 [6.7%] of 2615 vs 215 [8.4%] of 2569; 0.77, 0.63 0.94; p=0.012). Lorcaserin resulted in a non-significant increase in the rate of achievement of normoglycaemia in patients with prediabetes (185 [9.2%] vs 151 [7.6%]; 1.20, 0.97-1.49; p=0.093). In patients with diabetes, lorcaserin resulted in a reduction of 0.33% (95% CI 0.29-0.38; p<0.0001) in HbA1c compared with placebo at 1 year from a mean baseline of 53 mmol/mol (7.0%). In patients with diabetes at baseline, severe hypoglycaemia with serious complications was rare, but more common with lorcaserin (12 [0.4%] vs four [0.1%] events; p=0.054). INTERPRETATION: Lorcaserin decreases risk for incident diabetes, induces remission of hyperglycaemia, and reduces the risk of microvascular complications in obese and overweight patients, supporting the role of lorcaserin as an adjunct to lifestyle modification for chronic management of weight and metabolic health.

PMID- 30293785 TI - The Chromatin Reader ZMYND8 Regulates Igh Enhancers to Promote Immunoglobulin Class Switch Recombination. AB - Class switch recombination (CSR) is a DNA recombination reaction that diversifies the effector component of antibody responses. CSR is initiated by activation induced cytidine deaminase (AID), which targets transcriptionally active immunoglobulin heavy chain (Igh) switch donor and acceptor DNA. The 3' Igh super enhancer, 3' regulatory region (3'RR), is essential for acceptor region transcription, but how this function is regulated is unknown. Here, we identify the chromatin reader ZMYND8 as an essential regulator of the 3'RR. In B cells, ZMYND8 binds promoters and super-enhancers, including the Igh enhancers. ZMYND8 controls the 3'RR activity by modulating the enhancer transcriptional status. In its absence, there is increased 3'RR polymerase loading and decreased acceptor region transcription and CSR. In addition to CSR, ZMYND8 deficiency impairs somatic hypermutation (SHM) of Igh, which is also dependent on the 3'RR. Thus, ZMYND8 controls Igh diversification in mature B lymphocytes by regulating the activity of the 3' Igh super-enhancer. PMID- 30293792 TI - Nurses' Knowledge, Attitudes, and Barriers Toward Pain Management Among Postoperative Patients in Jordan. AB - PURPOSE: The purpose of this study was to measure nurses' knowledge, attitudes, and barriers regarding pain management (PM) of postoperative patients in Jordan. DESIGN: A descriptive survey research design was used. METHODS: This descriptive study adopted a modified version of the "Knowledge and Attitudes Survey Regarding Pain" tool, administered to 120 nurses working in surgical wards. FINDINGS: Nurses had inadequate knowledge of PM, with a mean knowledge score of 63.9%. Knowledge of PM and attitudes toward PM were associated positively with the age of the participant (P = .001), years of experience in the surgical area (P = .026), and academic degree of participants (P = .026). CONCLUSIONS: Surgical nurses in this study had low knowledge levels and poor attitudes regarding PM in postoperative patients. Unless identified barriers to PM are seriously addressed, this vital aspect of holistic care will continue to be marginalized. PMID- 30293793 TI - Impact of diabetes on coronary artery plaque volume by coronary CT angiography and subsequent adverse cardiac events. AB - BACKGROUND: To investigate the impact of diabetes on coronary artery total plaque volume (TPV) and adverse events in long-term follow-up. METHODS: One-hundred-and eight diabetic patients were matched to 324 non-diabetic patients, with respect to age, sex, body-mass index, hypertension, smoking habits, LDL and HDL cholesterol, family history for CAD as well as aspirin and statin medication. In all patients, TPV was quantified from coronary CT angiographies (CTA) using dedicated software. All-cause mortality, acute coronary syndrome and late revascularisation (>90 days) served as combined endpoint. RESULTS: Patients were followed for 5.6 years. The endpoint occurred in 18 (16.7%) diabetic and 26 (8.0%) non-diabetic patients (odds ratio 2.3, p = 0.03). Diabetic patients had significantly higher TPV than non-diabetic patients (55.1 mm3 [IQR: 6.2 and 220.4 mm3] vs. 24.9 mm3 [IQR: 0 and 166.7 mm3], p = 0.02). A TPV threshold of 110.5 mm3 provided good separation of diabetic and non-diabetic patients at higher and lower risk for adverse events. Noteworthy, diabetic and non-diabetic patients with a TPV<110.5 mm3 had comparable outcome (hazard ratio: 1.3, p = 0.59), while diabetic patients with TPV>110.5 mm3 had significantly higher incidence of adverse events (hazard ratio 2.3, p = 0.03) compared to non-diabetic patients with TPV>110.5 mm3. There was incremental prognostic value in diabetic and non diabetic patients over the Framingham Risk Score (Integrated Discrimination Improvement: 0.052 and 0.012, p for both <0.05). CONCLUSION: Diabetes is associated with significantly higher TPV, which is independent of other CAD risk factors. Quantification of TPV improves the identification of diabetic patients at higher risk for future adverse events.

AB - Fluorescence labeling of the target molecules using a small molecule-based probe is superior than a method using genetically expressed green fluorescence protein (GFP) in terms of convenience in its preparation and functionalization. Fluorophore-nitrilotriacetic acid (NTA) conjugates with several ester protecting groups were synthesized and evaluated for their cell membrane permeability by fluorescence microscopy analysis. One of the derivatives, acetoxymethyl (AM) protected NTA conjugate is hydrolyzed, resulting in intracellular accumulation, thus providing localized fluorescence intensity in cells. This modification is expected as an effective method for converting a non-cell membrane permeable NTA BODIPY conjugates to a cell membrane permeable derivatives. PMID- 30293796 TI - Discovery and anti-inflammatory evaluation of benzothiazepinones (BTZs) as novel non-ATP competitive inhibitors of glycogen synthase kinase-3beta (GSK-3beta). AB - Glycogen synthase kinase-3beta (GSK-3beta) has been identified to promote inflammation and its inhibitors have also been proven to treat some inflammatory mediated diseases in animal models. Non-ATP competitive inhibitors inherently have better therapeutical value due to their higher specificity than ATP competitive ones. In this paper, we designed and synthesized a series of new BTZ derivatives as non-ATP competitive GSK-3beta inhibitors. Kinetic analysis revealed two typical compounds 6j and 3j showed the different non-ATP competitive mechanism of substrate competition or allosteric modulation to GSK-3beta, respectively. As expected, the two compounds showed good specificity in a panel test of 16 protein kinases, even to the closest enzymes, like CDK-1/cyclin B and CK-II. The in vivo results proved that both compounds can greatly attenuate the LPS-induced acute lung injury (ALI) and diminish inflammation response in mice by inhibiting the mRNA expression of IL-1beta and IL-6. Western blot analysis demonstrated that they negatively regulated GSK-3beta, and the mechanism of the observed beneficial effects of the inhibitors may involve both the increased phosphorylation of the Ser9 residue on GSK-3beta and protein expression of Sirtuin 1 (SIRT1). The results support that such novel BTZ compounds have a protective role in LPS-induced ALI, and might be attractive candidates for further development of inflammation pharmacotherapy, which greatly thanks to their inherently high selectivities by the non-ATP competitive mode of action. Finally, we proposed suggesting binding modes by Docking study to well explain the impacts of compounds on the target site. PMID- 30293795 TI - Synthesis, in vitro and in vivo biological evaluation, COX-1/2 inhibition and molecular docking study of indole-N-acylhydrazone derivatives. AB - The objective of this work was to obtain and evaluate anti-inflammatory in vitro, in vivo and in silico potential of novel indole-N-acylhydrazone derivatives. In total, 10 new compounds (3a-j) were synthesized in satisfactory yields, through a condensation reaction in a single synthesis step. In the lymphoproliferation assay, using mice splenocytes, 3a and 3b showed inhibition of lymphocyte proliferation of 62.7% (+/-3.5) and 50.7% (+/-2), respectively, while dexamethasone presented an inhibition of 74.6% (+/-2.4). Moreover, compound 3b induced higher Th2 cytokines production in mice splenocytes cultures. The results for COX inhibition assays showed that compound 3b is a selective COX-2 inhibitor, but with less potency when compared to celecoxib, and compound 3a not presented selectivity towards COX-2. The molecular docking results suggest compounds 3a and 3b interact with the active site of COX-2 in similar conformations, but not with the active site of COX-1, and this may be the main reason to the COX-2 selectivity of compound 3b. In vivo carrageenan-induced paw edema assays were adopted for the confirmation of the anti-inflammatory activity. Compound 3b showed better results in suppressing edema at all tested concentrations and was able to induce an edema inhibition of 100% after 5 h of carrageenan injection at the 30 mg kg-1 dosage, corroborating with the COX inhibition and lymphoproliferation results. I addition to our experimental results, in silico analysis suggest that compounds 3a and 3b present a well-balanced profile between pharmacodynamics and pharmacokinetics. Thus, our preliminary results revealed the potentiality of a new COX-2 selective derivative in the modulation of the inflammatory process.

AB - Two series of 4-arylpiperazine- and 4-benzylpiperidine naphthyl ethers were designed based on structure-activity relationship (SAR) and docking model of reported monoamine neurotransmitters reuptake inhibitors. The compounds were synthesized in 3-simple steps and their biological activities were evaluated. Several compounds were proven to be potent inhibitors of serotonin and norepinephrine reuptake. Computer docking was performed to study the interaction of the most potent compound 35 with human serotonin transporter. The results of the analyses suggest that 4-arylpiperazine- and 4-benzylpiperidine naphthyl ethers might be promising antidepressants worthy of further studies. PMID- 30293798 TI - [Evaluation of the quality of long-term anticoagulation therapy with antivitamin K in atrial fibrillation]. AB - AIM: To assess the quality of long-term anticoagulation therapy with antivitamin K in patients with atrial fibrillation by measuring the TTR and to determine the factors associated with a good TTR. PATIENTS AND METHODS: This is an observational study conducted over a period of three years (from January 2013 until December 2015) in the outpatient clinic of cardiology of Farhat Hached hospital of Sousse, Tunisia. Pre-established individual plugs were used for data collection. The data analysis was performed using the SPSS Software, version 20. RESULTS: Overall, 200 patients were eligible. Half of the patients did not know the risks of AVK and 29.1% were unaware of their interest. The average TTR was 57.3+/-18.2%. Good control of anticoagulation was obtained in 24.5% of patients. Those with a>=70% were more autonomous, observant, of urban origin, living in Sousse and Kairouan, with good knowledge about AVK and having a small left atrium. The factors associated negatively with TTR were hypertension, diabetes, old AF, hematological diseases, high number of medications taken daily and the presence of mitral insufficiency, mitral valve replacement, a tricuspid insufficiency or a tricuspid plasty. CONCLUSION: The quality of AVK anticoagulation in AF patients is insufficient. Improving this indicator would reduce the morbidity and mortality associated with AVK treatment. PMID- 30293799 TI - Incidence and risk factors of peripheral venous catheter-related adverse events in cardiology department of a Tunisian university hospital: A prospective observational study. AB - AIM: The purpose of our study was to determine the incidence and risk factors of Peripheral Venous Catheter-Related Adverse Events (PVCAEs) in a cardiology department of a university hospital. PATIENTS AND METHODS: We carried out a prospective observational study from Mars 2017 to May 2017 in the cardiology department of the University Hospital of Farhat Hached in Sousse, Tunisia. During this period, we actively followed-up all inserted PVCs (every 12hours) from insertion up to 48hours after removal. Regression analyses were applied and significance limits were set at P<0.05. RESULTS: Data were analysed for 210 PVCs (794 PVC-days) in 148 patients. The incidence of PVCAEs was 33.33% with density of incidence of 8.81/1000 PVC-days. PVCAEs were mainly pain (50%) and mechanical events (31.42%). Infections accounted for 11.42%. The most frequent mechanical PVCAEs, was haematoma (15.71%). Multivariate analysis revealed as independent factors for the occurrence of PVCAEs: the hydro electrolytic nature of the injected product (OR=13.42, P<10-3), the medicinal nature of the injected product (OR=5.08, P=0.003), bad cutaneous state (OR=8.08, P=0.003), admission during nightshift (OR=3.76; P=0.014) and advanced age (OR=1.04, P=0.042). CONCLUSION: Multicenter studies would be very useful to better analyze risk factors associated with PVCAEs. PMID- 30293800 TI - Differentiation of focal organising pneumonia and peripheral adenocarcinoma in solid lung lesions using thin-section CT-based radiomics. AB - AIM: To evaluate the predictive role of radiomics based on computed tomography (CT) in discriminating focal organising pneumonia (FOP) from peripheral lung adenocarcinoma (LA). MATERIALS AND METHODS: Institutional research board approval was obtained for this retrospective study. One hundred and seventeen patients with FOP and 109 patients with LA who underwent thin-section CT from January 2011 to August 2017 were reviewed systematically and analysed. The clinical and radiological features were established as model A and multi-feature-based radiomics as model B. The diagnostic performance of model A, model B, and model A+B were evaluated and compared via receiver operating characteristic (ROC) curve analysis and logistic regression analysis. RESULTS: Sex, symptoms, necrosis, and the halo sign were identified as independent predictors of LA. The area under the ROC curve (Az value), accuracy, sensitivity, and specificity of model A were 0.839, 75.7%, 82.6%, and 69.2% respectively. Model B showed significantly higher accuracy than model A (83.6% versus 75.7%, p=0.032). The top four best-performing features, WavEnLH_s-3, WavEnHH_s-3, Teta3, and Volume, performed as independent factors for discriminating LA. Regression analysis indicated that model B had superior model fit than model A with Akaike information criterion (AIC) values of 73.6% versus 59.1%, respectively. Combining model A with model B is useful in achieving better diagnostic performance in discriminating FOP from LA: the Az value, accuracy, sensitivity, and specificity were 0.956, 87.6%, 85.3%, and 89.7% respectively. CONCLUSIONS: Radiomics based on CT exhibited better diagnostic accuracy and model fit than clinical and radiological features in discriminating FOP from LA. Combination of both achieved better diagnostic performance. PMID- 30293801 TI - Total virtual workflow in CAD-CAM bony reconstruction with a single step free fibular graft and immediate dental implants. AB - The Surgical reconstruction of defects of the face is challenging. Local and regional flaps have an important part to play, but large defects of bone and soft tissue are a greater problem. Microvascular tissue transfer has become the standard for such patients, and preoperative planning of bony reconstructions is now common. To use these preplanning tools best the implants should be placed in the prosthetically ideal place, and the bone positioned to surround the implants that is, truly backward planning of the position of the bone. The buccolingual angulation and the actual position of the implants during operation can be difficult to verify. Using commonly available software and 3-dimensional printing solutions, therefore, we have constructed an algorithm to optimise the position of these implants during the operation, and to get their position as close to the planned outcome as possible. This algorithm is adaptable to any implant system and is potentially possible in any implant or preplanning software unit. PMID- 30293802 TI - Transoral vertical ramus osteotomy fixed with Kirschner pins. AB - Transoral vertical ramus osteotomy (VRO) has been condemned because the condyle has the potential to sag, and because it needs lengthy maxillomandibular fixation. We have therefore introduced a simple method of fixation, and examined its effectiveness and complications. After the osteotomy, the proximal and distal segments are trimmed to adapt to each other. Four Kirschner (K) pins 0.9mm in diameter are inserted percutaneously from the proximal to the distal segment while the condyle is positioned in the glenoid fossa. This is followed by a brief period of maxillomandibular fixation. We have reviewed the records of 95 patients who had unilateral or bilateral vertical ramus osteotomy fixed with K pins, after which the mean (SD) period of fixation was 19 (11) days. Fixation failed in two patients because excursion of the jaw was either too heavy or too early. The fixations were redone. All other fixations remained stable, including the 20 dual jaw procedures in which VRO preceded maxillary osteotomy. The mean (SD) maximal mouth opening at final follow-up was 44 (7) mm, and in only one patient was it less than 30mm. Numbness of the lip or chin developed in seven patients, five of whom had other anterior mandibular procedures. Four patients had discomfort on palpation of the site of the pins, and one required removal. The new method was effective, and resulted in few complications within its limitations.

PMID- 30293805 TI - Risk factors for bleeding after dental extractions in patients over 60 years of age who are taking antiplatelet drugs. AB - The aim of this retrospective, single-centre study was to identify the risk factors for bleeding after dental extractions in patients aged over 60 who were being treated with antiplatelet drugs. A total of 338 patients who fulfilled the inclusion criteria were enrolled, and their personal and clinical details, and complications with bleeding after extraction, were retrieved and recorded. There were 182 men and 156 women (mean (SD) age 72 (8) years). A total of 469 teeth were extracted, with a mean (SD) of 1.4 (0.6) teeth/patient. Seventy-seven patients (23%) developed mild, and 55 (16%) severe, bleeding postoperatively. No patient developed a major cardiovascular or cerebrovascular event. We calculated the significance of the association of different variables with the occurrence of postoperative haemorrhage using a multivariate stepwise logistic regression model. The presence of three or more coexisting conditions, a complicated tooth extraction, and the use of two antiplatelet drugs were independent risk factors, while discontinuation of antiplatelet treatment four or more days before the tooth was extracted was a protective factor. This suggests that clinicians should assess the thrombotic risk associated with the interruption of antiplatelet drugs as well as the risk of bleeding for each patient before dental extraction. Strong and effective measures for haemostasis may be preferred over blind discontinuation of antiplatelet drugs. This study is registered in the Chinese Clinical Trial Registry (No. ChiCTR1800014355). PMID- 30293804 TI - Accuracy of a CAD/CAM surgical template for mandibular distraction: a preliminary study. AB - We have assessed the accuracy and clinical validation of virtual planning using a surgical template in 16 patients with hemifacial microsomia being treated by mandibular distraction osteogenesis. Virtual planning and simulation were first done on three-dimensional models. Distraction was simulated on the virtual model and the new morphology of the mandible was previewed. Both the position and direction of the distractor were calculated to achieve the optimal morphology. The templates were designed based on the virtual planning, and manufactured using a 3-dimensional printing technique. The template was designed to assist the surgeon to make the osteotomy and predrill the screw-holes to guide the distractor into position. The outcome was evaluated by comparing planned with postoperative outcomes. The osteotomy was made and the distractor implanted successfully under the guidance of the template in all patients. The linear and angular differences for the distractor were measured and reported using the root mean square deviation. There was no difficulty in using the templates. The largest linear root mean square deviation between the planned and the postoperative distractors was 0.93mm in the anteroposterior direction, and the largest in the horizontal plane was 4.64 degrees . We suggest that the preoperative plan can be transferred accurately to a patient using the template. PMID- 30293806 TI - Outcome of salvage procedures for recurrent oral and oropharyngeal cancer. AB - Despite advances in the primary treatment of oral and oropharyngeal cancer, many patients develop local or regional recurrence, or both, and when radiotherapy has already been used, operation provides the best chance of salvage for these patients. We have looked at the outcomes of salvage procedures in a single unit, including improved survival, morbidity, and treatment-related quality of life. Patients treated with salvage procedures were identified from a prospectively completed database. Overall and disease-free survival were analysed using Kaplan Meier curves and logrank tests. Functional, social, and emotional outcomes were assessed using the University of Washington Quality of Life Questionnaires. Twenty-nine patients were identified, of whom 24 had free flap reconstructions, and their estimated mean overall survival was 25 months (95% CI 20.4 to 29.2). Disease-free survival was significantly worse in patients with stage IV recurrences or in whom resection margins were close or invaded. Permanent gastrostomy was required in 15/29 patients, and four/29 needed a permanent tracheostomy. Answers to questionnaires showed that a large proportion of patients had considerable problems with speech, chewing, swallowing, and appearance. The decision on whether to treat recurrent head and neck cancer is a balance between improving survival and poor functional outcomes. The extent of disease and whether clear surgical margins can be achieved should be considered when treatment is recommended. PMID- 30293807 TI - Impact of reconstructive microsurgery on patients with cancer of the head and neck: a prospective study of quality of life, particularly in older patients. AB - Treatment of cancer of the head and neck often requires extended resection and major reconstructive surgery, both of which can have great functional and emotional impact. It is fundamental to evaluate the outcome with respect not only to the clinical aspects but also to the quality of life (QoL) perceived by the patients. In the light of the reported increasing incidence of oral cancer in older patients, we decided to see if there was an association between QoL and age. Between June 2015 and December 2016 we submitted the Italian version of the 36-item Short Form Health Survey (SF-36) to 30 patients (mean (range) age 65.5 (23-87) years) who had had resection and microsurgical reconstruction at the Ospedale Maggiore Policlinico of Milan. The questionnaires were completed before operation, and 12 months afterwards, and clinical and personal data were also collected. From the results of SF-36 we obtained the Short Form 12 (SF-12), Physical Health Composite Score (PCS), and Mental Health Composite Score (MCS) and looked at how age influences the variation in QoL scores. The variation between SF-36 and SF-12 results (preoperatively and postoperatively) did not seem to correlate with age. Our study confirmed that reconstructive microsurgery can be realistically proposed to older as well as younger patients because, according to the QoL index, older patients are able to manage (and therefore take advantage of) this complex surgical technique. PMID- 30293808 TI - Impact of a Direct Bedding Initiative on Left Without Being Seen Rates. AB - BACKGROUND: Left without being seen (LWBS) rates have become a key metric of emergency department (ED) flow, and high rates have been associated with poor patient outcomes, especially at busy urban, academic hospitals. OBJECTIVE: To assess a triage intervention's impact on LWBS rates among Emergency Severity Index (ESI) level 2 patients especially at risk for adverse outcomes. METHODS: We conducted a retrospective review at an urban academic center of LWBS rates prior to and after a "direct bedding" intervention, which directed patients triaged to ESI level 2 to be immediately placed in any available ED area, including those typically reserved for lower-acuity complaints. Our primary analysis employs an adjusted difference-in-difference-in-difference (DDD) approach using controls from the previous year and a nearby affiliate community hospital that did not participate in the intervention. RESULTS: Mean daily patient volume increased from 275 to 298 arrivals after the intervention. In the primary DDD analysis, odds of LWBS were lower after the intervention (adjusted odds ratio [OR] 0.56, 95% confidence interval [CI] 0.45-0.70, p < 0.001). LWBS was higher in the unadjusted analysis (unadjusted OR 1.39, 95% CI 1.31-1.49, p < 0.001), but still lower among ESI 1 or 2 patients targeted by the intervention (unadjusted OR 0.56, 95% CI 0.43-0.74, p < 0.001). CONCLUSIONS: "Direct bedding" of ESI 2 patients may expedite care for the sickest patients, reducing potential harm to patients who might otherwise LWBS, without compromising care for patients triaged to less acute ESI levels.

AB - Agronomically critical weeds that have evolved alongside crop species are characterized by rapid adaptation and invasiveness, which can result in an enormous reduction in annual crop yield worldwide. We discuss here recent genome based research studies on agricultural weeds and crop-weed interactions that reveal several major evolutionary innovations such as de-domestication, interactions mediated by allelochemical secondary metabolites, and parasitic genetic elements that play crucial roles in enhancing weed invasiveness in agricultural settings. We believe that these key studies will guide future research into the evolution of crop-weed interactions, and further the development of practical applications in agricultural weed control and crop breeding. PMID- 30293811 TI - Molecular Basis for Membrane Recruitment by the PX and C2 Domains of Class II Phosphoinositide 3-Kinase-C2alpha. AB - Phosphorylation of phosphoinositides by the class II phosphatidylinositol 3 kinase (PI3K) PI3K-C2alpha is essential for many processes, including neuroexocytosis and formation of clathrin-coated vesicles. A defining feature of the class II PI3Ks is a C-terminal module composed of phox-homology (PX) and C2 membrane interacting domains; however, the mechanisms that control their specific cellular localization remain poorly understood. Here we report the crystal structure of the C2 domain of PI3K-C2alpha in complex with the phosphoinositide head-group mimic inositol hexaphosphate, revealing two distinct pockets for membrane binding. The C2 domain preferentially binds to phosphatidylinositol 4,5 bisphosphate and phosphatidylinositol (3,4,5)-trisphosphate, and low-resolution structures of the combined PX-C2 module by small-angle X-ray scattering reveal a compact conformation in which cooperative lipid binding by each domain binding can occur. Finally, we demonstrate an unexpected role for calcium in perturbing the membrane interactions of the PX-C2 module, which we speculate may be important for regulating the activity of PI3K-C2alpha. PMID- 30293810 TI - Hydrogen-Deuterium Exchange Coupled to Top- and Middle-Down Mass Spectrometry Reveals Histone Tail Dynamics before and after Nucleosome Assembly. AB - Until recently, a major limitation of hydrogen-deuterium exchange mass spectrometry (HDX-MS) was that resolution of deuterium localization was limited to the length of the peptide generated during proteolysis. However, electron transfer dissociation (ETD) has been shown to preserve deuterium label in the gas phase, enabling better resolution. To date, this technology remains mostly limited to small, already well-characterized proteins. Here, we optimize, expand, and adapt HDX-MS tandem MS (MS/MS) capabilities to accommodate histone and nucleosomal complexes on top-down HDX-MS/MS and middle-down HDX-MS/MS platforms and demonstrate that near site-specific resolution of deuterium localization can be obtained with high reproducibility. We are able to study histone tail dynamics in unprecedented detail, which have evaded analysis by traditional structural biology techniques for decades, revealing important insights into chromatin biology. Together, the results of these studies highlight the versatility, reliability, and reproducibility of ETD-based HDX-MS/MS methodology to interrogate large protein and protein/DNA complexes. PMID- 30293813 TI - Keys to optimize the operating room efficiency. AB - Healthcare is in constant transformation. Health systems should focus on improving efficiency to meet a growing demand for high-quality, low-cost health care. The operating room is one of the biggest sources of revenue and one of the largest areas of expense. Therefore, operating room management is a critical key to success. The aim of this article is to analyze the current principles of organization, optimization and clinical management of the operating room and its impact on the quality and safety of care. PMID- 30293812 TI - Automatic Inference of Sequence from Low-Resolution Crystallographic Data. AB - At resolutions worse than 3.5 A, the electron density is weak or nonexistent at the locations of the side chains. Consequently, the assignment of the protein sequences to their correct positions along the backbone is a difficult problem. In this work, we propose a fully automated computational approach to assign sequence at low resolution. It is based on our surprising observation that standard reciprocal-space indicators, such as the initial unrefined R value, are sensitive enough to detect an erroneous sequence assignment of even a single backbone position. Our approach correctly determines the amino acid type for 15%, 13%, and 9% of the backbone positions in crystallographic datasets with resolutions of 4.0 A, 4.5 A, and 5.0 A, respectively. We implement these findings in an application for threading a sequence onto a backbone structure. For the three resolution ranges, the application threads 83%, 81%, and 64% of the sequences exactly as in the deposited PDB structures.

AB - INTRODUCTION: The use of the emergency department by uninsured patients with chronic health problems may adversely affect those patients' health outcomes. Successful interventions have involved the use of patient navigators to connect the uninsured adult population with medical coverage and a medical home. The aim of this project was to use principles of patient navigation in a nurse-led process improvement intervention to connect uninsured patients to medical homes. METHOD: ED nurses were trained to refer uninsured patients with chronic health problems to care coordinators when they were discharged from emergency departments. The care coordinator was provided by the Health Care District, a community-funded medical department. Patients were therefore connected to community-funded medical homes. RESULTS: ED nurses improved their knowledge about the overuse of the emergency department and successfully referred uninsured patients who were discharged. The referred patients successfully made contact with members of the Health Care District by phone or by attending their appointments. CONCLUSION: The role of patient navigators is essential in the emergency department. They assist patients to navigate through the various health care resources available in their communities, which can help to reduce ED overuse.

PMID- 30293816 TI - Does a Provider in Triage and Rapid Medical Evaluation Help With Left Without Being Seen Rates and ED Crowding? AB - INTRODUCTION: Attempting to reduce ED crowding, the ED team at a rural academic medical center and specialty hospital implemented rapid medical evaluation (RME) with and without a provider in triage (PIT). The purpose of this performance improvement project was to explore how these interventions affected crowding metrics of door-to-disposition time, ED length of stay (LOS), and left without being seen (LWBS) rates for all patients. METHODS: Using a prospective 2-group design, the pre-RME population served as the historical control group, and postintervention groups included both RME with and without PIT. Group comparisons of crowding metrics included pre- and post-RME with and without PIT. RESULTS: There were no statistically significant differences in any of the crowding metrics for the emergency severity index (ESI) 3 groups pre- or post-RME. However, mean door-to-disposition times for the post-RME ESI 5 population were shorter compared with the pre-RME ESI 5 patients (2:59:23 vs. 2:00: 42; P = 0.037). Analysis of the post-RME population with and without PIT did not demonstrate significant differences across ESI 3 or 5 groups. Comparisons of post RME data revealed a significant increase in ED LOS for all admitted patients regardless of their ESI (P = 0.023) and also door-to-disposition times for ESI level-4 patient groups, both with and without PIT (P = 0.022). IMPLICATIONS FOR PRACTICE: The findings support other studies demonstrating that RME can have positive impact on ED crowding metrics for some patients. Although PIT took longer for some patients, anecdotal findings revealed benefits related to direct discharges and admission occurring during the RME process. PMID- 30293817 TI - Identification of Novel Cdc7 Kinase Inhibitors as Anti-Cancer Agents that Target the Interaction with Dbf4 by the Fragment Complementation and Drug Repositioning Approach. AB - BACKGROUND: Cdc7-Dbf4 is a conserved serine/threonine kinase that plays an important role in initiation of DNA replication and DNA damage tolerance in eukaryotic cells. Cdc7 has been found overexpressed in human cancer cell lines and tumor tissues, and the knockdown of Cdc7 expression causes an p53-independent apoptosis, suggesting that Cdc7 is a target for cancer therapy. Only a handful Cdc7 kinase inhibitors have been reported. All Cdc7 kinase inhibitors, including PHA-767491, were identified and characterized as ATP-competitive inhibitors. Unfortunately, these ATP-competitive Cdc7 inhibitors have no good effect on clinical trial. METHODS: Here, we have developed a novel drug-screening platform to interrupt the interaction between Cdc7 and Dbf4 based on Renilla reniformis luciferase (Rluc)-linked protein-fragment complementation assay (Rluc-PCA). Using drug repositioning approach, we found several promising Cdc7 inhibitors for cancer therapy from a FDA-approved drug library. FINDINGS: Our data showed that dequalinium chloride and clofoctol we screened inhibit S phase progression, accumulation in G2/M phase, and Cdc7 kinase activity. In addition, in vivo mice animal study suggests that dequalinium chloride has a promising anti-tumor activity in oral cancer. Interestingly, we also found that dequalinium chloride and clofoctol sensitize the effect of platinum compounds and radiation due to synergistic effect. In conclusion, we identified non-ATP-competitive Cdc7 kinase inhibitors that not only blocks DNA synthesis at the beginning but also sensitizes cancer cells to DNA damage agents. INTERPRETATION: The inhibitors will be a promising anti-cancer agent and enhance the therapeutic effect of chemotherapy and radiation for current cancer therapy.

PMID- 30293819 TI - The role of diffusion weighted imaging as supplement to dynamic contrast enhanced breast MRI: Can it help predict malignancy, histologic grade and recurrence? AB - RATIONALE AND OBJECTIVES: To evaluate the value of adding Diffusion Weighted Imaging (DWI) with Apparent Diffusion Coefficient (ADC) mapping to dynamic contrast enhanced (DCE-MRI) to distinguish benign from malignant pathology subtypes and tumor recurrence. METHOD AND MATERIALS: In this retrospective IRB approved study, 956 consecutive patients underwent bilateral breast MRI between 1/2015 and 12/2015, with 156 BIRADS 4, 5, or 6 lesions detected in 111 patients. DWI imaging at B0, B100, B600, B1000 was performed with DCE-MRI. Values for diffusion and ADC images were recorded by two fellowship-trained breast radiologists. Mean ADC and signal intensity (SI) values were correlated with histology, tumor grade, hormone receptors (ER, PR, and HER-2)and Oncotype DX scores, when available. p <= 0.05 was considered significant. RESULTS: Of 156 lesions, there were 59 (38%) benign lesions, 24 (15%) Ductal Carcinoma In-Situ, 47 (30%) Invasive Ductal Carcinoma (IDC), 15 (10%) Invasive Lobular Carcinoma (ILC) and 2 (2%) Mucinous carcinoma (MC), five (5%) mixed IDC and ILC, and four (4%) other, including tubular and rare types of malignancy. Mean ADC values for malignancy were significantly lower than for benign lesions (1085 +/- 343 * 10-6 vs 1481 +/- 276 * 10-6 mm2/s), which is highly predictive (area under curve = 0.82). In addition, tumors with PR negativity and Oncotype score >=18 (intermediate to high risk for recurrence) demonstrated significantly lower ADC values. SI at B100 and B600 was helpful in distinguishing benign versus IDC. There was no significant correlation between ADC values and tumor grade or ER/HER2 status. CONCLUSION: ADC value is important factor in distinguishing malignancy, differentiating tumors with higher Oncotype score, and PR negativity. Therefore, it can be used as an important tool to assist appropriate treatment selection. PMID- 30293818 TI - Long non-coding RNA LINC-01572:28 inhibits granulosa cell growth via a decrease in p27 (Kip1) degradation in patients with polycystic ovary syndrome. AB - BACKGROUND: Disordered folliculogenesis is a key feature of polycystic ovary syndrome (PCOS), but the underlying molecular mechanism remains unclear. METHODS: Long non-coding RNA (lncRNA) expression in luteinized granulosa cells (hLGCs) derived from women with and without PCOS were analyzed using microarray and qRT PCR. Immortalized human granulosa cell lines were cultured for proliferation assays after transfection with the LINC-01572:28 over-expression vector in the presence or absence of p27 siRNA. Protein expression analysis, rescue assays, and RNA immunoprecipitation (RIP) were used to confirm the LINC-01572:28 substrate. FINDINGS: LINC-01572:28 and p27 protein were elevated whereas proliferating cell nuclear antigen protein was decreased in the hLGCs of women with PCOS. LINC 01572:28 expression was positively correlated with basal testosterone levels. Over-expression of LINC-01572:28 inhibited cell proliferation and impeded G1/S transition, which were partially reversed by siRNA-mediated p27 knockdown. INTERPRETATION: Our findings, therefore, suggest that LINC-01572:28 suppresses cell proliferation and cell cycle progression by reducing the degradation of p27 protein via SKP2 binding. PMID- 30293820 TI - Small signal averaged transfer function model and controller design of modular solid state transformers. AB - The prime objective of this paper is to design and develop simple and efficient closed loop controllers independently for each of the conversion stages of a Modular Solid State Transformer (MSST) for low/medium voltage applications. The controller design is based on small signal averaged transfer function model using topology independent black box approach. Hence it can be universally adopted for any choice of topologies. The independently designed controllers enhance the modularity of the apparatus such that extension and reduction of ac/dc voltage and power levels are possible by addition and removal of modules as and when required. This paves way for easy maintenance and replacement of modules. Further, the cost and complexity in control is reduced to enable large scale market penetration of the apparatus. Time and frequency response plots are illustrated to validate the performance of the individual converters with the designed closed loop controllers. The simple control design adopted for MSST is shown to mitigate power quality issues to a greater extent possible. Simulation and experimental results are presented which substantiate the appropriateness of the small signal model and hence the controllers designed for the MSST. PMID- 30293821 TI - Oxytocin Transforms Firing Mode of CA2 Hippocampal Neurons. AB - Oxytocin is an important neuromodulator in the mammalian brain that increases information salience and circuit plasticity, but its signaling mechanisms and circuit effect are not fully understood. Here we report robust oxytocinergic modulation of intrinsic properties and circuit operations in hippocampal area CA2, a region of emerging importance for hippocampal function and social behavior. Upon oxytocin receptor activation, CA2 pyramidal cells depolarize and fire bursts of action potentials, a consequence of phospholipase C signaling to modify two separate voltage-dependent ionic processes. A reduction of potassium current carried by KCNQ-based M channels depolarizes the cell; protein kinase C activity attenuates spike rate of rise and overshoot, dampening after hyperpolarizations. These actions, in concert with activation of fast-spiking interneurons, promote repetitive firing and CA2 bursting; bursting then governs short-term plasticity of CA2 synaptic transmission onto CA1 and, thus, efficacy of information transfer in the hippocampal network. PMID- 30293822 TI - Ephaptic Coupling Promotes Synchronous Firing of Cerebellar Purkinje Cells. AB - Correlated neuronal activity at various timescales plays an important role in information transfer and processing. We find that in awake-behaving mice, an unexpectedly large fraction of neighboring Purkinje cells (PCs) exhibit sub millisecond synchrony. Correlated firing usually arises from chemical or electrical synapses, but, surprisingly, neither is required to generate PC synchrony. We therefore assessed ephaptic coupling, a mechanism in which neurons communicate via extracellular electrical signals. In the neocortex, ephaptic signals from many neurons summate to entrain spiking on slow timescales, but extracellular signals from individual cells are thought to be too small to synchronize firing. Here we find that a single PC generates sufficiently large extracellular potentials to open sodium channels in nearby PC axons. Rapid synchronization is made possible because ephaptic signals generated by PCs peak during the rising phase of action potentials. These findings show that ephaptic coupling contributes to the prevalent synchronization of nearby PCs. PMID- 30293823 TI - Neural Coding of Leg Proprioception in Drosophila. AB - Animals rely on an internal sense of body position and movement to effectively control motor behavior. This sense of proprioception is mediated by diverse populations of mechanosensory neurons distributed throughout the body. Here, we investigate neural coding of leg proprioception in Drosophila, using in vivo two photon calcium imaging of proprioceptive sensory neurons during controlled movements of the fly tibia. We found that the axons of leg proprioceptors are organized into distinct functional projections that contain topographic representations of specific kinematic features. Using subclass-specific genetic driver lines, we show that one group of axons encodes tibia position (flexion/extension), another encodes movement direction, and a third encodes bidirectional movement and vibration frequency. Overall, our findings reveal how proprioceptive stimuli from a single leg joint are encoded by a diverse population of sensory neurons, and provide a framework for understanding how proprioceptive feedback signals are used by motor circuits to coordinate the body. PMID- 30293824 TI - Effects of freeze-thaw on the biomechanical and structural properties of the rat Achilles tendon. AB - Rodent models are commonly used to investigate tendon healing, with the biomechanical and structural properties of the healed tendons being important outcome measures. Tendon storage for later testing becomes necessary when performing large experiments with multiple time-points. However, it is unclear whether freezing rodent tendons affects their material properties. Thus the aim of this study was to determine whether freezing rat Achilles tendons affects their biomechanical or structural properties. Tendons were frozen at either -20 degrees C or -80 degrees C directly after harvesting, or tested when freshly harvested. Groups of tendons were subjected to several freeze-thaw cycles (1, 2, and 5) within 3 months, or frozen for 9 months, after which the tendons were subjected to biomechanical testing. Additionally, fresh and thawed tendons were compared morphologically, histologically and by transmission electron microscopy. No major differences in biomechanical properties were found between fresh tendons and those frozen once or twice at -20 degrees C or -80 degrees C. However, deterioration of tendon properties was found for 5-cycle groups and both long term freezing groups; after 9 months of freezing at -80 degrees C the tear resistance of the tendon was reduced from 125.4 +/- 16.4N to 74.3 +/- 18.4N (p = 0.0132). Moreover, tendons stored under these conditions showed major disruption of collagen fibrils when examined by transmission electron microscopy. When examined histologically, fresh samples exhibited the best cellularity and proteoglycan content of the enthesis. These properties were preserved better after freezing at -80 degrees C than after freezing at -20 degrees C, which resulted in markedly smaller chondrocytes and less proteoglycan content. Overall, the best preservation of histological integrity was seen with tendons frozen once at -80 degrees C. In conclusion, rat Achilles tendons can be frozen once or twice for short periods of time (up to 3 months) at -20 degrees C or -80 degrees C for later testing. However, freezing for 9 months at either -20 degrees C or -80 degrees C leads to deterioration of certain parameters. PMID- 30293825 TI - Evaluation of pulmonary artery stenosis in congenital heart disease patients using functional diagnostic parameters: An in vitro study. AB - Congenital pulmonary artery (PA) stenosis is often associated with abnormal PA hemodynamics including increased pressure drop (Deltap) and reduced asymmetric flow (Q), which may result in right ventricular dysfunction. We propose functional diagnostic parameters, pressure drop coefficient (CDP), energy loss (Eloss), and normalized energy loss (E-loss) to characterize pulmonary hemodynamics, and evaluate their efficacy in delineating stenosis severity using in vitro experiments. Subject-specific test sections including the main PA (MPA) bifurcating into left and right PAs (LPA, RPA) with a discrete LPA stenosis were manufactured from cross-sectional imaging and 3D printing. Three clinically relevant stenosis severities, 90% area stenosis (AS), 80% AS, and 70% AS, were evaluated at different cardiac outputs (COs). A benchtop flow loop simulating pulmonary hemodynamics was used to measure Q and Deltap within the test sections. The experimental Deltap-Q characteristics along with clinical data were used to obtain pathophysiologic conditions and compute the diagnostic parameters. The pathophysiologic QLPA decreased as the stenosis severity increased at a fixed CO. CDPLPA, Eloss,LPA (absolute), and E-loss,LPA (absolute) increased with an increase in LPA stenosis severity at a fixed CO. Importantly, CDPLPA and E loss,LPA had reduced variability with CO, and distinct values for each LPA stenosis severity. Under variable CO, a) CDPLPA values were 14.5-21.0 (70% AS), 60.7- 2.2 (80% AS), >= 261.6 (90% AS), and b) E-loss,LPA values (in mJ per QLPA) were -501.9 to -1023.8 (70% AS), -1247.6 to -1773.0 (80% AS), -1934.5 (90% AS). Hence, CDPLPA and E-loss,LPA are expected to assess the true functional severity of PA stenosis. PMID- 30293826 TI - Assessment of ocular redness measurements obtained with keratograph 5M and correlation with subjective grading scales. AB - OBJECTIVE: To examine correlations between ocular redness scores provided by the Keratograph 5M and those determined using two image-based grading scales. METHODS: Observational prospective cross-sectional study. Two hundred and twenty six eyes of two hundred and twenty six participants (175 patients using anti glaucoma eye drops and 51 subjects untreated). All subjects were scored automatically using the keratograph 5M. These redness scores (RS) were then correlated with the gradings provided by the Efron and McMonnies/Chapman-Davies scale (MC-D) scales (two observers). RESULTS: Excellent reproducibility was observed for both the Efron (weighted K=0.897, 95% CI 0.823-0.904) and MC-D (weighted K=0.783, 95% CI 0.752-0.795) scales. Keratograph RS and the scores obtained with both Efron (Spearman's Rho=0.43, P<0.001) and MC-D (Spearman's Rho=0.48, P<0.001) scales were significantly correlated. RS for the bulbar and limbal - nasal and temporal quadrants also correlated moderately with the two subjective scales. Through Bland Altman analysis, poor agreement was detected between the objective and subjective methods: agreement values for the Efron scale or MC-D scale (matching scorers between observers) versus overall RS showed high biases (-15.58 and -22.05 respectively) and wide limits of agreement (LOA) ( 46.169 to 15.005 and -52.534 to 8.19 respectively). Lowest bias was observed between temporal limbal RS and Observer 2 Efron score (-0.04). CONCLUSIONS: Although it emerged as a reliable objective method, the keratograph 5M overestimated the scores compared with the subjective grading scales when used to grade the degree of ocular redness. Therefore, they should not be interchangeable methods. PMID- 30293827 TI - Thoracolumbar Osteomyelitis Secondary to Systemic Mycobacterium Chimaera Infection Status Post Aortic Valve Replacement.

AB - OBJECTIVE: To analyze the predictive factors associated with prolonged mechanical ventilation (PMV) and prolonged duration of inotropic support (PDIS) following anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) surgery with possible concomitant mitral valve procedure (MVP) in a relatively young population. DESIGN: A retrospective case-control study. SETTING: Fuwai hospital. PARTICIPANTS: Pediatric patients with ALCAPA surgery from July 2010 to October 2017. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: PMV was defined as a mechanical ventilation time >=48 hours and PDIS as a duration of inotropic support >=6 days. Univariate analysis, logistic regression analysis, and receiver operating characteristic curve analysis were used to identify independent predictors of PMV and PDIS. The independent predictors of PMV were found to be the left ventricular end-diastolic diameter z-score (LVEDDz), estimate of glomerular filtration rate (eGFR) and maximum vasoactive-inotropic score (VISm). The odds ratios and 95% confidence intervals for these predictors of PMV were the following: LVEDDz, 1.58 (1.19-2.09); eGFR, 0.96 (0.93-0.998); and VISm, 1.08 (1.01-1.17). The predictor of PDIS was LVEDDz at 1.65 (1.26-2.15). One patient died during hospitalization, and there was no reoperation. Thirty-seven patients received concomitant MVP with no hospital mortality. At discharge, mitral regurgitation (MR) had improved in all patients with MR. Patients with PMV were associated with more acute kidney injury, PDIS, and longer ICU and hospital stays. CONCLUSIONS: In relatively young individuals who received ALCAPA surgery and possible concomitant MVP, short-term outcomes are favorable. Based on their experience bias, the authors recommend combining LVEDDz, eGFR, and VISm to predict PMV and applying LVEDDz for PDIS. PMID- 30293831 TI - Continuous Ropivacaine Infusion Offers No Benefit in Treating Postoperative Pain After Cardiac Surgery. AB - OBJECTIVE: One multimodal pain management method for reducing postoperative opioid need after cardiac surgery is to continuously infuse local anesthetic into a median sternotomy wound. Previous studies have shown contradictory results with this method; therefore, no consensus exists on its effectiveness. The authors tested the effectiveness of continuous 0.2% ropivacaine infusion into a sternotomy wound after cardiac surgery. DESIGN: Prospective, randomized, double blinded, placebo-controlled trial. SETTING: Single-institution, tertiary-level, university hospital. PARTICIPANTS: Total of 90 patients undergoing coronary artery bypass grafting or heart valve surgery. INTERVENTIONS: Patients were assigned randomly to receive 0.2% ropivacaine or placebo into a sternotomy wound for 48 hours postoperatively. Pain was controlled with standardized oxycodone boluses after surgery and patient-controlled analgesia oxycodone after extubation; total oxycodone consumption was recorded. Pain was assessed 3 times daily, at rest and during deep breathing, with the visual analogue scale. MEASUREMENTS AND MAIN RESULTS: Forty-seven patients were assigned to receive ropivacaine and 43 to receive placebo infusion. Cumulative oxycodone consumption was 97 +/- 27 mg with ropivacaine and 96 +/- 29 mg with placebo (p = 0.813). Pain scores were similar between groups, both at rest (p = 0.630) and during deep breathing (p = 0.793). Adverse event incidences and surgical wound infection rates were similar between groups. CONCLUSION: Continuous 0.2% ropivacaine infusions at the median sternotomy wound did not reduce postoperative pain or opioid consumption during the first 48 hours after cardiac surgery. This technique apparently was not beneficial for post-sternotomy pain treatment.

PMID- 30293833 TI - Comparison of the Efficacy of Ultrasound-Guided Serratus Anterior Plane Block, Pectoral Nerves II Block, and Intercostal Nerve Block for the Management of Postoperative Thoracotomy Pain After Pediatric Cardiac Surgery. AB - OBJECTIVE: The aim of this study was to compare the relative efficacy of ultrasound-guided serratus anterior plane block (SAPB), pectoral nerves (Pecs) II block, and intercostal nerve block (ICNB) for the management of post-thoracotomy pain in pediatric cardiac surgery. DESIGN: A prospective, randomized, single blind, comparative study. SETTING: Single-institution tertiary referral cardiac center. PARTICIPANTS: The study comprised 108 children with congenital heart disease requiring surgery through a thoracotomy. INTERVENTIONS: Children were allocated randomly to 1 of the 3 groups: SAPB, Pecs II, or ICNB. All participants received 3 mg/kg of 0.2% ropivacaine for ultrasound-guided block after induction of anesthesia. Postoperatively, intravenous paracetamol was used for multimodal and fentanyl was used for rescue analgesia. MEASUREMENTS AND MAIN RESULTS: A modified objective pain score (MOPS) was evaluated at 1, 2, 4, 6, 8, 10, and 12 hourspost-extubation. The early mean MOPS at 1, 2, and 4 hourswas similar in the 3 groups. The late mean MOPS was significantly lower in the SAPB group compared with that of the ICNB group (p < 0.001). The Pecs II group also had a lower MOPS compared with the ICNB group at 6, 8, and 10 hours(p < 0.001), but the MOPS was comparable at hour 12 (p = 0.301). The requirement for rescue fentanyl was significantly higher in ICNB group in contrast to the SAPB and Pecs II groups. CONCLUSION: SAPB and Pecs II fascial plane blocks are equally efficacious in post thoracotomy pain management compared with ICNB, but they have the additional benefit of being longer lasting and are as easily performed as the traditional ICNB.

PMID- 30293836 TI - Permanent prostate brachytherapy monotherapy with I-125 for low- and intermediate risk prostate cancer: Outcomes in 974 patients. AB - PURPOSE: To report outcomes of patients undergoing low-dose-rate (LDR) brachytherapy and investigate factors associated with biochemical failure and survival. METHODS: Consecutive patients undergoing LDR with I-125 at our institution between 1998 through 2013 for primary intact prostate cancer were examined. Those with low- and intermediate-risk disease receiving LDR with a minimum of 2 years followup and at least one post-LDR prostate-specific antigen (PSA) were included. RESULTS: About 974 patients satisfied inclusion criteria. With median followup of 72 months, biochemical failure occurred in 45 patients. Freedom from biochemical failure as defined by the Phoenix criterion was 96% and 88% at 5 and 10 years, worse for intermediate risk as compared with low risk, with 10-year freedom from biochemical failure of 76% versus 92% (hazard ratio [HR] = 3.7, p < 0.001), respectively. On multivariable analysis, increased prebiopsy PSA, Gleason 4 + 3, and no androgen deprivation therapy were associated with biochemical failure. Gleason 4 + 3 was the factor most strongly associated with biochemical failure (HR = 7.01, p < 0.001). No examined factors were associated with local failure. Gleason 4 + 3 disease increased the likelihood of distant metastasis (HR = 12.4, p = 0.003) and prostate cancer-specific death (HR = 13.2, p < 0.001). No difference in outcomes between patients with Gleason 3 + 3 versus 3 + 4 was observed. CONCLUSIONS: LDR brachytherapy provided excellent outcomes in this large series of patients treated for localized organ-confined prostate cancer. Local recurrence at 10 years was low at 2.1%. Primary Gleason 4 + 3, higher pretreatment PSA, and no receipt of androgen deprivation therapy were the only factors associated with biochemical failure. Primary Gleason 4 disease was also predictive of distant metastases and decreased prostate cancer-specific survival. PMID- 30293837 TI - RSK-MASTL Pathway Delays Meiotic Exit in Mouse Zygotes to Ensure Paternal Chromosome Stability. AB - During vertebrate fertilization, sperm chromatin remodeling occurs concomitantly with maternal chromosome segregation at anaphase II, leading to simultaneous formation of two pronuclei. In mammals, these processes take much longer than in other vertebrates. Here, we explore the molecular basis and physiological importance of this mammalian-specific temporal regulation using mouse oocytes. We demonstrate the involvement of protein phosphatase in temporal regulation. Early onset of pronuclear formation causes paternal-biased abnormalities in pronuclear morphology and chromosome segregation at the first mitosis. After oocyte activation, CDK1-MASTL-ENSA, a protein phosphatase 2A-suppressive pathway, remains active despite the absence of cyclin B and contributes to delayed pronuclear formation. Sustained activation of MASTL involves ribosomal S6 kinase (RSK)-mediated phosphorylation of Thr297, which is conserved only among mammalian MASTLs. Our findings reveal the role of RSK in mouse oocytes, showing that the RSK-MASTL pathway allows mammalian-specific prolonged meiotic exit and ensures the faithful conversion from sperm to paternal pronuclei. PMID- 30293840 TI - Human SEIPIN Binds Anionic Phospholipids. AB - The biogenesis of lipid droplets (LDs) and the development of adipocytes are two key aspects of mammalian fat storage. SEIPIN, an integral membrane protein of the endoplasmic reticulum (ER), plays a critical role in both LD formation and adipogenesis. The molecular function of SEIPIN, however, has yet to be elucidated. Here, we report the cryogenic electron microscopy structure of human SEIPIN at 3.8 A resolution. SEIPIN exists as an undecamer, and this oligomerization state is critical for its physiological function. The evolutionarily conserved lumenal domain of SEIPIN forms an eight-stranded beta sandwich fold. Both full-length SEIPIN and its lumenal domain can bind anionic phospholipids including phosphatidic acid. Our results suggest that SEIPIN forms a scaffold that helps maintain phospholipid homeostasis and surface tension of the ER. PMID- 30293841 TI - Implementing an evidence-based psychological intervention for suicidal thoughts and behaviors on an inpatient unit: Process, challenges, and initial findings. AB - OBJECTIVE: Barriers to implementing evidence-based psychological treatments for suicidal thoughts and behaviors in busy hospital settings exist. Transdiagnostic interventions may serve to facilitate training in evidence-based treatment and more efficiently treat individuals with multiple psychiatric comorbidities. We describe the rationale for, process of, and initial data from implementing the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) on an inpatient unit for adults with suicidal thoughts and behaviors and affective disorders. METHOD: We analyzed clinical intake and outcome data from a subsample of patients admitted during the six months before and six months after UP implementation (n = 133 and n = 61, respectively), and available acceptability and fidelity data from the month following UP implementation. RESULTS: Patients improved significantly over the course of inpatient treatment before and after UP implementation. Effects for depression, suicidal ideation, anxiety, and emotion regulation were similar before and after UP implementation. Patients generally reported high acceptability of the UP and clinician fidelity to the protocol was variable during the month following UP implementation. CONCLUSIONS: The UP may be a promising evidence-based intervention for inpatient settings that treat individuals with suicidal thoughts and behaviors. Well-controlled, randomized trials are needed to determine efficacy, particularly regarding suicidal behavior after discharge. PMID- 30293838 TI - Inheritance of CENP-A Nucleosomes during DNA Replication Requires HJURP. AB - Centromeric chromatin defines the site of kinetochore formation and ensures faithful chromosome segregation. Centromeric identity is epigenetically specified by the incorporation of CENP-A nucleosomes. DNA replication presents a challenge for inheritance of centromeric identity because nucleosomes are removed to allow for replication fork progression. Despite this challenge, CENP-A nucleosomes are stably retained through S phase. We used BioID to identify proteins transiently associated with CENP-A during DNA replication. We found that during S phase, HJURP transiently associates with centromeres and binds to pre-existing CENP-A, suggesting a distinct role for HJURP in CENP-A retention. We demonstrate that HJURP is required for centromeric nucleosome inheritance during S phase. HJURP co purifies with the MCM2-7 helicase complex and, together with the MCM2 subunit, binds CENP-A simultaneously. Therefore, pre-existing CENP-A nucleosomes require an S phase function of the HJURP chaperone and interaction with MCM2 to ensure faithful inheritance of centromere identity through DNA replication. PMID- 30293839 TI - A Membrane Transporter Is Required for Steroid Hormone Uptake in Drosophila. AB - Steroid hormones are a group of lipophilic hormones that are believed to enter cells by simple diffusion to regulate diverse physiological processes through intracellular nuclear receptors. Here, we challenge this model in Drosophila by demonstrating that Ecdysone Importer (EcI), a membrane transporter identified from two independent genetic screens, is involved in cellular uptake of the steroid hormone ecdysone. EcI encodes an organic anion transporting polypeptide of the evolutionarily conserved solute carrier organic anion superfamily. In vivo, EcI loss of function causes phenotypes indistinguishable from ecdysone- or ecdysone receptor (EcR)-deficient animals, and EcI knockdown inhibits cellular uptake of ecdysone. Furthermore, EcI regulates ecdysone signaling in a cell autonomous manner and is both necessary and sufficient for inducing ecdysone dependent gene expression in culture cells expressing EcR. Altogether, our results challenge the simple diffusion model for cellular uptake of ecdysone and may have wide implications for basic and medical aspects of steroid hormone studies. PMID- 30293842 TI - Emergency Department patients with suicide risk: Differences in care by acute alcohol use. AB - OBJECTIVE: To compare Emergency Department (ED) care of suicidal patients with and without documented acute alcohol use. METHODS: Retrospective chart review of randomly sampled patient visits (n = 800; January 2014 to December 2015) at an urban ED with universal screening for suicide risk. Eligible visits were by adults (18+ years) who screened positive for suicide risk at the ED visit (i.e., suicidal ideation in past two weeks or suicide attempt in past six months). Analyses compared those with and without documentation of acute alcohol use. RESULTS: Among these patients with suicide risk, 19% had documented acute alcohol use (versus 43% with no use and 38% without documentation); individuals with acute alcohol use were more often male and aged 35-59 years. Overall, 62% were evaluated by a mental health professional in the ED. Individuals with acute alcohol use were significantly less likely (vs those without use) to be evaluated by a mental health professional in the ED (odds ratio 0.49, 95%CI 0.28-0.87) after adjustment for age, recent suicide ideation, current suicide plan, self harm as a chief complaint, contact with family, and ED disposition. CONCLUSIONS: Although alcohol use can increase suicide risk, ED patients with acute use appear to receive less thorough suicide risk assessments. PMID- 30293843 TI - Advanced airway management in out of hospital cardiac arrest: A systematic review and meta-analysis. AB - OBJECTIVES: To assess the difference in survival and neurological outcomes between endotracheal tube (ETT) intubation and supraglottic airway (SGA) devices used during out-of-hospital cardiac arrest (OHCA). METHODS: A systematic search of five databases was performed by two independent reviewers until September 2018. Included studies reported on (1) OHCA or cardiopulmonary resuscitation, and (2) endotracheal intubation versus supraglottic airway device intubation. Exclusion criteria (1) stimulation studies, (2) selectively included/excluded patients, (3) in-hospital cardiac arrest. Odds Ratios (OR) with random effect modelling was used. Primary outcomes: (1) return of spontaneous circulation (ROSC), (2) survival to hospital admission, (3) survival to hospital discharge, (4) discharge with a neurologically intact state. RESULTS: Twenty-nine studies (n = 539,146) showed that overall, ETT use resulted in a heterogeneous, but significant increase in ROSC (OR = 1.44; 95%CI = 1.27 to 1.63; I2 = 91%; p < 0.00001) and survival to admission (OR = 1.36; 95%CI = 1.12 to 1.66; I2 = 91%; p = 0.002). There was no significant difference in survival to discharge or neurological outcome (p > 0.0125). On sensitivity analysis of RCTs, there was no significant difference in ROSC, survival to admission, survival to discharge or neurological outcome (p > 0.0125). On analysis of automated chest compression, without heterogeneity, ETT provided a significant increase in ROSC (OR = 1.55; 95%CI = 1.20 to 2.00; I2 = 0%; p = 0.0009) and survival to admission (OR = 2.16; 95%CI = 1.54 to 3.02; I2 = 0%; p < 0.00001). CONCLUSIONS: The overall heterogeneous benefit in survival with ETT was not replicated in the low risk RCTs, with no significant difference in survival or neurological outcome. In the presence of automated chest compressions, ETT intubation may result in survival benefits.

PMID- 30293848 TI - Symposium review: Embryo survival-A genomic perspective of the other side of fertility. AB - The majority of embryonic loss in cattle occurs within the first 3 to 4 wk of pregnancy, and there are currently no accurate predictors of pregnancy outcome. Existing embryo quality assessment methods include morphological evaluation and embryo biopsy. These methods are not accurate and carry some health risks to the developing embryo, respectively. Therefore, there is need to identify noninvasive biomarkers such as microRNA that can predict embryo quality and pregnancy outcome. Furthermore, researchers need a better understanding of the dynamic interaction between the mother and the embryo. The transcriptome of the uterus shows plasticity that depends on the embryo type so that the expression level of some genes for in vivo embryos would be different from that of in vitro-produced embryos. Similarly, the embryonic transcriptome and epigenome change in response to different environmental factors such as stress, diet, disease, and physiological status of the mother. This embryo-mother crosstalk could be better understood by investigating the molecular signaling that occurs at different stages of embryonic development. Although transcriptomics is a useful tool to assess the roles of genes and pathways in embryo quality and maternal receptivity, it does not provide the exact functions of these genes, and it shows correlation rather than causality. Therefore, an in-depth functional genomic analysis is needed for better understanding of the molecular mechanisms controlling embryo development. In this review, we discuss recent genomic technologies such as RNA interference, gapmer technology, and genome editing techniques used in humans and livestock to elucidate the molecular mechanisms of genes affecting embryo development. PMID- 30293849 TI - [Is cancer a factor or a marker of cardiovascular risk in women?] AB - Cardiovascular diseases and cancers are the 2 main causes of mortality in industrialized countries. Cancer and cardiovascular disease share molecular and pathophysiological mechanisms involved in both cardiovascular disease and cancer development. Some prescribed therapies for primary or secondary prevention of cardiovascular disease (statin, aspirin) may have effects on the cancer plan. Physical activity would be particularly beneficial in reducing the risk of colorectal cancer, breast and endometrial cancer in women. The control of risk factors is associated with a reduction in the incidence of cancers. PMID- 30293850 TI - [Place of natriuretic peptides in the early diagnosis of heart failure in community medicine]. AB - Diagnosis of heart failure is too late. Symptoms of heart failure are non specific. Brain natriuretic peptides allow the diagnosis of heart failure in pauci-symptomatic patients, with a threshold of 35pg/mL for BNP and 125pg/mL for NT-proBNP. Left ventricular dysfunction, either diastolic or systolic, remains asymptomatic for a long time. In diabetic and/or hypertensive patients, natriuretic peptides, can be used to diagnose asymptomatic left ventricular dysfunction, with a threshold of 125pg/mL NT-proBNP. Treatment blocking the renin angiotensin-aldosterone system in diabetic patients with NT-proBNP levels of 125pg/mL can prevent onset of heart failure. Screening of subjects at risk of heart failure (diabetics, hypertensive) is possible thanks to natriuretic peptides.

PMID- 30293853 TI - Development of a novel resection and cutting guide for mandibular reconstruction using free fibula flap. AB - INTRODUCTION: The authors developed a semi-standardised resection and cutting guide for mandibular reconstruction with free fibula flap based on data of mandible sizes and angles. METHODS: After analyzing the angles and lengths of mandibular angles and segments on computer tomography, a partly-adjustable resection guide for the mandible and cutting guide for the fibula were designed. RESULTS: After testing and optimizing the guides on plastic models and cadavers, the guides were successfully used for mandible resection and reconstruction with free fibula flap in 8 patients with segmental mandibulectomy. Application of the cutting and resection guides and functional results like occlusion and aesthetic appearence were satisfactory in all cases. CONCLUSIONS: The developed semi standardised device is a helpful instrument for facilitating reconstruction of segmental mandibular defects with free fibula flaps. No extensive preoperative preparation and 3D printing is necessary which can avoid additional costs for virtual planning. Especially for lower budget health systems this can be an alternative to virtual planning. PMID- 30293852 TI - Selective Elimination of Culture-Adapted Human Embryonic Stem Cells with BH3 Mimetics. AB - The selective survival advantage of culture-adapted human embryonic stem cells (hESCs) is a serious safety concern for their clinical application. With a set of hESCs with various passage numbers, we observed that a subpopulation of hESCs at late passage numbers was highly resistant to various cell death stimuli, such as YM155, a survivin inhibitor. Transcriptome analysis from YM155-sensitive (YM155S) and YM155-resistant (YM155R) hESCs demonstrated that BCL2L1 was highly expressed in YM155R hESCs. By matching the gene signature of YM155R hESCs with the Cancer Therapeutics Response Portal dataset, BH3 mimetics were predicted to selectively ablate these cells. Indeed, short-course treatment with a sub-optimal dose of BH3 mimetics induced the spontaneous death of YM155R, but not YM155S hESCs by disrupting the mitochondrial membrane potential. YM155S hESCs remained pluripotent following BH3 mimetics treatment. Therefore, the use of BH3 mimetics is a promising strategy to specifically eliminate hESCs with a selective survival advantage. PMID- 30293854 TI - Community-level social capital and cognitive decline after a natural disaster: A natural experiment from the 2011 Great East Japan Earthquake and Tsunami. AB - We examined prospectively whether community-level social capital can mitigate the adverse effects of natural disaster on cognitive decline in the aftermath of the 2011 Great East Japan Earthquake and Tsunami. The baseline for our natural experimental study was established seven months before the disaster in a survey of older community-dwelling adults who lived in Iwanuma City, Japan, located 80 km west of the epicenter. Two and a half years after the disaster, we conducted a follow-up survey of survivors to gather information about their personal experiences during the disaster (n = 3560; 82.1% follow-up rate). Our primary outcome was the level of cognitive disability (measured on an 8-level scale) assessed within people's homes. Factor analysis established two subscales of community social capital: a cognitive dimension (perceptions of community social cohesion) and a structural dimension (informal socializing and social participation). The prevalence of cognitive decline at follow-up (11.5%) was three times higher than at baseline (4.2%). Our multiple membership multilevel model indicated that pre-versus post-disaster increases in community-level informal socializing and social participation were associated with lower risk of cognitive decline (coefficient = -0.12, 95% confidence interval: -0.20 to -0.04). In addition, social capital mitigated the risk of cognitive decline due to housing damage (interaction effect coefficient = -0.07, 95% confidence interval: 0.14 to -0.01). Community-level informal socializing and social participation buffers the impact of housing damage on cognitive decline in the aftermath of natural disaster. Relocating residents together with other community members may help to preserve community social capital and improve the cognitive resilience of older survivors.

AB - Inflammation is an essential response to injury and its timely and adequate resolution permits tissue repair and avoidance of chronic inflammation. Ageing is associated with increased inflammation, sub-optimal resolution and these act as drivers for a number of ageing-associated pathologies. We describe the role played by specialised proresolving lipid mediators (SPMs) in the resolution of inflammation and how insufficient levels of these mediators, or compromised responsiveness may play a role in the pathogenesis of many ageing-associated pathologies, e.g. Alzheimer's Disease, atherosclerosis, obesity, diabetes and kidney disease. Detailed examination of the resolution phase of inflammation highlights the potential to harness these lipid mediators and or mimetics of their bioactions, in particular, their synthetic analogues to promote effective resolution of inflammation, without compromising the host immune system. PMID- 30293858 TI - Outcomes of revision arthroplasty for shoulder periprosthetic joint infection: a three-stage revision protocol. AB - BACKGROUND: This study evaluated outcomes after treatment of shoulder periprosthetic joint infection (PJI) with a 3-stage revision protocol consisting of (1) debridement, explantation, and cement spacer placement, followed by parenteral antibiotics; (2) open biopsy and debridement; and (3) reimplantation if cultures were negative. We hypothesized this protocol would eradicate persistent infection while producing excellent functional and subjective outcomes, and there would be no difference in these parameters for patients with shoulder PJI compared with patients with revision for aseptic indications. METHODS: We retrospectively analyzed a prospectively collected revision shoulder arthroplasty cohort to identify shoulder PJI patients treated with a 3-stage protocol. Demographics, culture data, range of motion, and patient-reported outcomes were collected. Outcomes for patients with shoulder PJI and revision to RTSA were compared with patients revised to RTSA for noninfectious indications. Significance was defined as P < .05. RESULTS: There were 28 cases of shoulder PJI in 27 patients (age, 66.4 +/- 11.2 years,); of these, 21 shoulders were revised to RTSA, and 7 shoulders were revised to hemiarthroplasty. There was no recurrent infection at a mean 32-month follow-up. One year after surgery, mean forward flexion was 110 degrees +/- 41 degrees and abduction was 106 degrees +/- 42 degrees . Mean final American Shoulder and Elbow Surgeons subjective score was 66.5 +/- 23.3. The 21 shoulders with PJI revised to RTSA had no differences for functional and subjective outcomes compared with revised patients without shoulder PJI. CONCLUSIONS: A 3-stage revision protocol for shoulder PJI reliably eradicated infection. Patients with PJI revised to RTSA can have similar outcomes as patients with noninfectious revision to RTSA. PMID- 30293859 TI - Molecular mechanism underlying orofacial antinociceptive activity of Vanillosmopsis arborea Baker (Asteraceae) essential oil complexed with beta cyclodextrin. AB - BACKGROUND: Vanillosmopsis arborea Baker has recognized economic value owing to the high content of (-)-alpha-bisabolol (BISA) in the essential oil of its stem (EOVA). The antinociceptive effect of EVOA has already been demonstrated, and beta-cyclodextrin (betaCD) is known to improve the analgesic effect of various substances. PURPOSE: Thus, we aimed to evaluate the orofacial antinociceptive effect of a complex containing EOVA-betaCD in rodents. METHODS: EOVA was obtained by simple hydrodistillation, and the essential oil was complexed with betaCD. The animals (n = 6/group) were treated orally with EOVA-betaCD (10 or 50 mg/kg), or vehicle (control), and subjected to cutaneous orofacial nociception (formalin, capsaicin, acidic saline or glutamate), corneal (hypertonic saline) or temporomandibular (formalin) tests. The expression of FOS protein was analyzed in the spinal cord. Molecular docking was performed using the 5-HT3 and M2 receptors and BISA. RESULTS: The oral administration of EOVA-betaCD reduced nociceptive behaviour. Moreover, EOVA-betaCD decreased FOS expression. The molecular docking study indicates that BISA interacts with 5-HT3 and M2 receptors, indicating the potential mechanism of action of the tested compound. CONCLUSIONS: Our results indicate that EOVA-betaCD possesses orofacial antinociceptive effect, indicating that this complex can be used in analgesic drug development. PMID- 30293860 TI - Evaluation of a Tool to Identify Child Sex Trafficking Victims in Multiple Healthcare Settings. AB - PURPOSE: Estimate the prevalence of child sex trafficking (CST) among patients seeking care in multiple healthcare settings; evaluate a short screening tool to identify victims in a healthcare setting. METHODS: This cross-sectional observational study involved patients from 16 sites throughout the U.S.: five pediatric emergency departments, six child advocacy centers, and five teen clinics. Participants included English-speaking youth ages 11-17 years. For emergency department sites, inclusion criteria included a chief complaint of sexual violence. Data on several domains were gathered through self-report questionnaires and examiner interview. Main outcomes included prevalence of CST among eligible youth; sensitivity, specificity, positive/negative predictive values, and positive/negative likelihood ratios for a CST screening tool. RESULTS: Eight hundred and ten participants included 91 (11.52%) youth from emergency departments, 395 (48.8%) from child advocacy centers, and 324 (40.0%) from teen clinics. Overall prevalence of CST was 11.1%: 13.2% among emergency department patients, 6.3% among child advocacy center patients, and 16.4% among teen clinic patients, respectively. The screen had a sensitivity, specificity, and positive likelihood ratio of 84.44% (75.28, 91.23), 57.50% (53.80, 61.11), and 1.99% (1.76, 2.25), respectively. CONCLUSIONS: This study demonstrates a significant rate of CST among patients presenting to emergency departments (for sexual violence complaints), child advocacy centers, and teen clinics. A six-item screen showed relatively good sensitivity and moderate specificity. Negative predictive value was high. Intervention for a "positive" screen may identify victims and help prevent high-risk youth from becoming victimized. This is one of the first CST screening tools specifically developed and evaluated in the healthcare setting. PMID- 30293861 TI - Implementation of an Alcohol Medical Amnesty Policy at an Urban University With a Collegiate-Based Emergency Medical Services Agency. AB - PURPOSE: Medical amnesty policies (MAPs) at universities attemptto encourage students to seek emergency medical care by reducing disciplinary sanctions. This study analyzed how a MAP affected requests for emergency medical help to a collegiate-based emergency medical services (CBEMS) agency for alcohol-related issues. METHODS: This before-and-after study analyzed CBEMS call data for the 6 semesters prior to and after MAP implementation. Extracted data included patient demographics, dispatch time, and requests for advanced life support (ALS) resources. RESULTS: Following MAP introduction, increases were observed in alcohol-related calls/day in the fall semesters (0.84 vs. 0.93; p < 0.01). The median time of calls decreased; 1:20 a.m. versus 12:59 a.m. (median difference 21 minutes, p < 0.001). Finally, ALS was requested less often (9.0% vs. 3.7%; odds ratio 0.39; p < 0.01). CONCLUSIONS: MAP implementation at a university with a CBEMS is associated with a higher call volume, requests for service that occur earlier in the evening, and reduction in ALS requests for alcohol-related emergencies. PMID- 30293862 TI - Electronic Cigarette Use and Attempts to Quit Smoking Cigarettes Among Adolescents in Taiwan. AB - PURPOSE: This study assessed the relationship between electronic cigarette (e cigarette) use and attempts to quit smoking cigarettes by adolescent smokers in Taiwan. METHODS: Data were obtained from the cross-sectional Taiwan Global Youth Tobacco Survey conducted annually between 2014 and 2016, which included adolescents aged 12-18years. The independent variable was e-cigarette use in the previous 30days. The outcome variable was attempts to quit cigarette smoking during the previous 12 months. We controlled for the following variables: year of survey, gender, grade, monthly income/allowance, numbers of cigarettes per day, smoking status of parents and friends, use of other tobacco products, access to free tobacco products, assistance in quitting smoking, and exposure to anti tobacco campaigns. RESULTS: Among cigarettes smokers, the prevalence of current e cigarette use (in the previous 30 days) increased from 9.82% (2014) to 27.46% (2016), whereas attempts to quit smoking cigarettes decreased slightly from 71.31% (2014) to 70.59% (2016). Current e-cigarette use (OR = 1.21) was positively associated with attempts to quit cigarette smoking. Smokers who observed anti-tobacco media messages (OR = 1.12), attended antismoking classes (OR = 1.17), were influenced by warnings on cigarette packages (OR = 3.32), or received help to quit (OR = 3.11) were more likely to have attempted to quit cigarettes. CONCLUSIONS: We identified factors correlated with attempts to quit smoking, and recommend that the government continue monitoring electronic cigarette use, combat smoking in the media, provide antismoking classes, and expand health warnings on cigarette packages. PMID- 30293863 TI - Negative Consequences Associated With Witnessing Severe Violent Events: The Role of Control-Related Beliefs. AB - PURPOSE: Control-related beliefs are defined as beliefs in one's ability to cause an effect in one's environment. With recent increases in violence in some cities, understanding the impact of exposure to violence on these beliefs is important. The present study examined whether witnessing severe community violence during early adolescence was associated with trajectories of control-related beliefs, and whether these trajectories were associated with mental and behavioral health outcomes in early adulthood. METHOD: Using data from a longitudinal preventive intervention study, we modeled trajectories of control-related beliefs using growth mixture modeling from 9th through 12th grade. The violence exposure of interest was witnessing severe community violence, defined as seeing someone being shot, stabbed, or killed. Early adulthood outcomes examined were post high school suicide attempt; having a criminal justice record; and having a diagnosis of substance use disorder, major depressive disorder, or antisocial personality disorder. RESULTS: The latent growth mixture model identified three trajectories of control-related beliefs: a low stable trajectory, a high increasing trajectory, and a moderate stable trajectory. Participants who were exposed to severe violent events were significantly more likely to be in the low trajectory. Further, those in the low trajectory were significantly more likely to experience several negative outcomes. CONCLUSION: Results suggest that witnessing severe forms of community violence impacts control-related belief trajectories and that trajectories characterized by low feelings of control are associated with adverse outcomes in early adulthood. PMID- 30293864 TI - A review on microelectrode recording selection of features for machine learning in deep brain stimulation surgery for Parkinson's disease. AB - OBJECTIVE: This study seeks to systematically review the selection of features and algorithms for machine learning and automation in deep brain stimulation surgery (DBS) for Parkinson's disease. This will assist in consolidating current knowledge and accuracy levels to allow greater understanding and research to be performed in automating this process, which could lead to improved clinical outcomes. METHODS: A systematic literature review search was conducted for all studies that utilized machine learning and DBS in Parkinson's disease. RESULTS: Ten studies were identified from 2006 utilizing machine learning in DBS surgery for Parkinson's disease. Different combinations of both spike independent and spike dependent features have been utilized with different machine learning algorithms to attempt to delineate the subthalamic nucleus (STN) and its surrounding structures. CONCLUSION: The state-of-the-art algorithms achieve good accuracy and error rates with relatively short computing time, however, the currently achievable accuracy is not sufficiently robust enough for clinical practice. Moreover, further research is required for identifying subterritories of the STN. SIGNIFICANCE: This is a comprehensive summary of current machine learning algorithms that discriminate the STN and its adjacent structures for DBS surgery in Parkinson's disease. PMID- 30293866 TI - Intestinal Dysmotility Syndromes following Systemic Infection by Flaviviruses. AB - Although chronic gastrointestinal dysmotility syndromes are a common worldwide health problem, underlying causes for these disorders are poorly understood. We show that flavivirus infection of enteric neurons leads to acute neuronal injury and cell death, inflammation, bowel dilation, and slowing of intestinal transit in mice. Flavivirus-primed CD8+ T cells promote these phenotypes, as their absence diminished enteric neuron injury and intestinal transit delays, and their adoptive transfer reestablished dysmotility after flavivirus infection. Remarkably, mice surviving acute flavivirus infection developed chronic gastrointestinal dysmotility that was exacerbated by immunization with an unrelated alphavirus vaccine or exposure to a non-infectious inflammatory stimulus. This model of chronic post-infectious gastrointestinal dysmotility in mice suggests that viral infections with tropism for enteric neurons and the ensuing immune response might contribute to the development of bowel motility disorders in humans. These results suggest an opportunity for unique approaches to diagnosis and therapy of gastrointestinal dysmotility syndromes. PMID- 30293865 TI - An Endothelial-to-Adipocyte Extracellular Vesicle Axis Governed by Metabolic State. AB - We have uncovered the existence of extracellular vesicle (EV)-mediated signaling between cell types within the adipose tissue (AT) proper. This phenomenon became evident in our attempts at generating an adipocyte-specific knockout of caveolin 1 (cav1) protein. Although we effectively ablated the CAV1 gene in adipocytes, cav1 protein remained abundant. With the use of newly generated mouse models, we show that neighboring endothelial cells (ECs) transfer cav1-containing EVs to adipocytes in vivo, which reciprocate by releasing EVs to ECs. AT-derived EVs contain proteins and lipids capable of modulating cellular signaling pathways. Furthermore, this mechanism facilitates transfer of plasma constituents from ECs to the adipocyte. The transfer event is physiologically regulated by fasting/refeeding and obesity, suggesting EVs participate in the tissue response to changes in the systemic nutrient state. This work offers new insights into the complex signaling mechanisms that exist among adipocytes, stromal vascular cells, and, potentially, distal organs. PMID- 30293867 TI - Endoscopic versus percutaneous drainage of post-operative peripancreatic fluid collections following pancreatic resection. AB - BACKGROUND: Post-operative peripancreatic fluid collection (PFC) is a common complication following pancreatic resection which can be managed with endoscopic or percutaneous drainage. METHODS: Patients who underwent either endoscopic or percutaneous drainage of post-operative PFC were extracted from a prospectively maintained database. The two groups were matched for surgery type, presence of a surgical drain and timing of drainage. RESULTS: Thirty-nine matched patients were identified in each group with a median age of 62 years. For primary drainage, technical success was achieved in almost all patients in both endoscopic and percutaneous groups (100% and 97%, p = NS); clinical success was achieved in 67% and 59%, respectively (p = 0.63). At least one "salvage" drainage procedure was required in 13 endoscopic patients versus 16 in the percutaneous group. Clinical success was achieved following the first salvage. Procedure in 85% of the endoscopic patients and 88% of the percutaneous patients (p = 0.62). Stent/drain duration (59 vs 33 days, p < 0.001) and number of post-procedural CT studies (2 vs 1, p = 0.02) were significantly higher in the endoscopic group. There was no difference in length of stay, complication, or recurrence between the two groups. CONCLUSION: Endoscopic drainage of post-operative PFC appears to be safe and effective with comparable success rates and outcomes to percutaneous drainage. PMID- 30293868 TI - Clinical criteria for integrated molecular pathology in intraductal papillary mucinous neoplasm: less is more. AB - BACKGROUND: For pancreatic cysts with negative cytology, Integrated Molecular Pathology (IMP) is a malignancy risk score integrating clinical criteria with pancreatic cyst fluid DNA profiling. Aside from main pancreatic duct (MPD) diameter, integrated clinical criteria are not International Consensus Guidelines High-Risk Stigmata. We predicted exclusion of clinical criteria except MPD diameter could simplify the IMP and better distinguish invasive/malignant disease. METHODS: Records of >1100 patients with IPMN were reviewed retrospectively. Sensitivity, specificity, and accuracy of conventional IMP for invasive/malignant disease was compared to DNA profile including only MPD >=10mm (IMP-10.) Invasive outcomes were invasive-IPMN/adenocarcinoma on surgical pathology, pathologic or radiographic evidence of invasive/metastatic disease during surveillance. Malignant outcomes included high grade dysplastic IPMN (HGD IPMN). RESULTS: 225 patients who met study criteria underwent 283 IMP evaluations: 98 followed by surgery, 185 followed by >= 23 months surveillance. IMP-10 had greater specificity (90.1% vs. 73.7%) and accuracy (89.8% vs. 74.2%) for invasive disease compared to IMP in surgery + surveillance patients, but lower sensitivity (77.8% vs. 88.9%). Trends were similar in surgery patients alone and malignant outcome analyses. CONCLUSION: IMP-10 excludes less-reliable clinical factors resulting in greater accuracy in predicting invasive/malignant disease and fewer patients with benign disease being recommended for surgery. PMID- 30293869 TI - Multiagent neoadjuvant chemotherapy and tumor response are associated with improved survival in pancreatic cancer. AB - BACKGROUND: Neoadjuvant therapy (NT) for borderline resectable pancreatic cancer (BRPC) has evolved to include multi-agent regimens and chemoradiation. We report our experience and compare outcomes of initially resectable pancreatic cancer (IRPC) vs BRPC receiving NT across two eras of chemotherapy regimens. METHODS: Data were collected retrospectively on pancreaticoduodenectomy patients between January 2008 and October 2015. Outcomes and survival were compared based on patient, laboratory and treatment factors. RESULTS: 195 patients were included and 133 had IRPC and 62 BRPC. IRPC operations were shorter (449 min vs 520 min, p = 0.003), had less blood loss (663 ml vs 954 ml, p = 0.002) and involved fewer vascular resections (29% vs 76%, p = 0.002). The rate of R0 resection was identical (82%, p = 1) and the IRPC group had higher node-positive ratio (19.3% vs 7.2% p < 0.0001). 15 patients received a single agent regimen while 47 received multi-agent regimens with 90% receiving radiation.Survival was similar between BRPC and IRPC (log-rank p = 0.7). Histopathologic response (CAP grade 0 or 1) was not associated with survival (p = 0.13), but completion of >=4 cycles of multi-agent pre-operative chemotherapy (p = 0.001) and complete response to NT (p = 0.04) were significant predictors of survival. CONCLUSIONS: BRPC patients treated with NT have similar morbidity and survival to their IRPC counterparts. Pathologic response and modern NT are associated with improved survival. PMID- 30293870 TI - The protective effect of Irisin against ischemia-reperfusion injury after perforator flap grafting in rats. AB - BACKGROUND: Ischemia-reperfusion injury is one of the reasons for failure of flap grafting. In the present study, we investigated the protective effect of irisin on the survival of perforator flaps in rats. METHODS: A total of 48 adult Sprague Dawley rats were divided into 2 groups and subjected to vascular clipping of perforator flap. Rats in the experimental group (n = 24) received daily tail intravenous injection of irisin (2 ng/g) for 3 days, while the rest rats in the control group (n = 24) received injection of saline solution of the same dose. On the 7th post-operative day, the surviving area of the flaps were recorded as the percentage of the total flap area. Histology study with haematoxylin and eosin staining were performed in all flaps. Flaps were also evaluated with lead oxide gelatine-enhanced flap angiography. Immunohistochemical study was performed to evaluate the expression of ErG, a marker of vascular endothelial cells. The tissue of "choke vessels" was excised for quantification of p-Akt/Akt by western blot assay on the 7th post-operative day. RESULTS: On the 7th post-operative day, the percentage of surviving flap area was significantly larger in the rats with irisin administration (experimental group), compared with the control group (P = 0.011). The density of microvessels was significantly higher in the experimental group (P = 0.03) in the histological study and angiography, with a higher expression level of ErG in the immunochemical study (P = 0.01). The p-Akt/Akt was also higher in the experimental group in Western blotting analysis (P < 0.001). CONCLUSION: Irisin has a beneficial effect on protecting perforator flaps from ischemic-reperfusion injury following the flap grafting surgery. It was potentially achieved by promoting proliferation of vascular endothelial cells after flap revascularization. Upregulation of the PI3K/Akt signaling pathway was potentially related with this process. PMID- 30293871 TI - Early removal of metal stents in walled off pancreatic necrosis. PMID- 30293872 TI - Gene expression analysis of embryonic pancreas development master regulators and terminal cell fate markers in resected pancreatic cancer: A correlation with clinical outcome. AB - BACKGROUND: Despite the recent introduction of new drugs and the development of innovative multi-target treatments, the prognosis of pancreatic ductal adenocarcinoma (PDAC) remains very poor. Even when PDAC is resectable, the rate of local or widespread disease recurrence remains particularly high. Currently, reliable prognostic biomarkers of recurrence are lacking. We decided to explore the potential usefulness of pancreatic developmental regulators as biomarkers of PDAC relapse. METHODS: We analyzed by quantitative real-time PCR the mRNA of selected factors involved either in pancreatic organogenesis (ISL1, NEUROD1, NGN3, NKX2.2, NKX6.1, PAX4, PAX6, PDX1 and PTF1alpha) or associated with terminally committed pancreatic cells (CHGA, CHGB, GAD2, GCG, HNF6alpha, INS, KRT19, SYP) in 17 PDAC cell lines and in frozen tumor samples from 41 PDAC patients. RESULTS: High baseline levels of the ISL1, KRT19, PAX6 and PDX1 mRNAs in PDAC cell lines, were risk factors for time-dependent xenograft appearance after subcutaneous injection in CD1-Nude mice. Consistently, in human PDAC samples, high levels of KRT19 mRNA were associated with reduced overall survival and earlier recurrence. Higher levels of PDX1 or PAX6 mRNAs were instead associated with a higher frequency of local recurrence. CONCLUSIONS: Our findings suggest that selected factors associated with pancreas development or its terminal differentiation might be implicated in mechanisms of PDAC progression and/or metastatic spread and that the measurement of their mRNA in tumors might be potentially used to improve patient prognostic stratification and prediction of the relapse site. PMID- 30293873 TI - Prognostic Effect of Adenosine-related Genetic Variants in Metastatic Colorectal Cancer Treated With Bevacizumab-based Chemotherapy. AB - BACKGROUND: Adenosine has an immunosuppressive and angiogenic modulation of the tumor microenvironment. The present study explored the efficacy of single nucleotide polymorphisms (SNPs) in adenosine-related molecules for patients with metastatic colorectal cancer treated with bevacizumab-based chemotherapy. PATIENTS AND METHODS: We analyzed genomic DNA extracted from 451 samples from 3 independent cohorts: a discovery cohort of 107 patients treated with FOLFIRI (5 fluorouracil, leucovorin, oxaliplatin, irinotecan) plus bevacizumab in FIRE-3 (ClinicalTrials.gov identifier, NCT00433927); a validation cohort of 215 patients with FOLFIRI plus bevacizumab in TRIBE (ClinicalTrials.gov identifier, NCT00719797); and a control cohort of 129 patients treated with FOLFIRI plus cetuximab in FIRE-3. The relationship between the selected SNPs and clinical outcomes was analyzed. RESULTS: In the discovery cohort, patients with any C allele in CD39 rs11188513 had significantly shorter median progression-free survival compared with those with the T/T variant (11.3 vs. 13.1 months; hazard ratio [HR], 1.70; 95% confidence interval [CI], 1.04-2.77; P = .022) on univariate analysis. Also, their overall survival (OS) was shorter (27.4 vs. 49.9 months; HR, 2.10; 95% CI, 1.07-4.10; P = .031) on univariate and multivariable analyses. The significant association between CD39 rs11188513 and OS was confirmed in the validation cohort (25.8 vs. 31.6 months; HR, 1.53; 95% CI, 1.09 2.15; P = .013). CD73 rs2229523 and A2BR rs2015353 in the discovery cohort and CD39 rs2226163 in the validation cohort showed significant correlations with OS on univariate and multivariable analyses. None of SNPs were significant in the cetuximab control cohort. CONCLUSION: Selected SNPs in the adenosine pathway could affect the clinical outcomes of patients with metastatic colorectal cancer treated with FOLFIRI plus bevacizumab.

PMID- 30293875 TI - A predictive method for hepatitis disease diagnosis using ensembles of neuro fuzzy technique. AB - BACKGROUND: Hepatitis is an inflammation of the liver, most commonly caused by a viral infection. Supervised data mining techniques have been successful in hepatitis disease diagnosis through a set of datasets. Many methods have been developed by the aids of data mining techniques for hepatitis disease diagnosis. The majority of these methods are developed by single learning techniques. In addition, these methods do not support the ensemble learning of the data. Combining the outputs of several predictors can result in improved accuracy in classification problems. This study aims to propose an accurate method for the hepatitis disease diagnosis by taking the advantages of ensemble learning. METHODS: We use Non-linear Iterative Partial Least Squares to perform the data dimensionality reduction, Self-Organizing Map technique for clustering task and ensembles of Neuro-Fuzzy Inference System for predicting the hepatitis disease. We also use decision trees for the selection of most important features in the experimental dataset. We test our method on a real-world dataset and present our results in comparison with the latest results of previous studies. RESULTS: The results of our analyses on the dataset demonstrated that our method performance is superior to the Neural Network, ANFIS, K-Nearest Neighbors and Support Vector Machine. CONCLUSIONS: The method has potential to be used as an intelligent learning system for hepatitis disease diagnosis in the healthcare. PMID- 30293876 TI - Candida auris: a global fungal public health threat. PMID- 30293878 TI - Long-term safety and efficacy of alirocumab in patients with heterozygous familial hypercholesterolemia: An open-label extension of the ODYSSEY program. AB - BACKGROUND AND AIMS: ODYSSEY OLE (open-label extension; NCT01954394) included patients diagnosed with heterozygous familial hypercholesterolemia (HeFH), receiving maximally tolerated statins, who had completed one of four Phase 3 double-blind parent studies (all 18 months' duration), with the aim to assess longer-term safety and efficacy of alirocumab. METHODS: Patients received starting dose alirocumab 75 mg every 2 weeks (Q2W; patients from FH I, FH II, and LONG TERM) or alirocumab 150 mg Q2W (patients from HIGH FH). Low-density lipoprotein cholesterol (LDL-C) levels were blinded to the patient and physician until Week 8; from Week 8, LDL-C levels were communicated to physicians. From Week 12, dose adjustment from 75 to 150 mg Q2W, or vice versa, was possible per physician's clinical judgment according to patient's LDL-C levels. RESULTS: Patients who had received alirocumab (n = 655) compared with placebo (n = 330) in the parent studies exhibited similar rates of treatment-emergent adverse events (TEAEs; 87.3% vs. 83.9%) during OLE (2.5 years median alirocumab exposure). Overall, 33 patients (3.4%) experienced TEAEs leading to permanent treatment discontinuation. At Week 8, alirocumab reduced mean LDL-C by 44.2% (reduction from 151.9 mg/dL at parent study baseline to 84.9 mg/dL); reduction in LDL-C was consistent to Week 96 of OLE. Reductions in lipid parameters were similar regardless of treatment allocation in the parent study. CONCLUSIONS: In patients with HeFH, no unexpected long-term safety concerns were observed with alirocumab compared with previously published data; durability of LDL-C-lowering over 3 years (including 1.5 years of parent trials) was demonstrated. PMID- 30293877 TI - Multiple introductions and subsequent transmission of multidrug-resistant Candida auris in the USA: a molecular epidemiological survey. AB - BACKGROUND: Transmission of multidrug-resistant Candida auris infection has been reported in the USA. To better understand its emergence and transmission dynamics and to guide clinical and public health responses, we did a molecular epidemiological investigation of C auris cases in the USA. METHODS: In this molecular epidemiological survey, we used whole-genome sequencing to assess the genetic similarity between isolates collected from patients in ten US states (California, Connecticut, Florida, Illinois, Indiana, Maryland, Massachusetts, New Jersey, New York, and Oklahoma) and those identified in several other countries (Colombia, India, Japan, Pakistan, South Africa, South Korea, and Venezuela). We worked with state health departments, who provided us with isolates for sequencing. These isolates of C auris were collected during the normal course of clinical care (clinical cases) or as part of contact investigations or point prevalence surveys (screening cases). We integrated data from standardised case report forms and contact investigations, including travel history and epidemiological links (ie, patients that had shared a room or ward with a patient with C auris). Genetic diversity of C auris within a patient, a facility, and a state were evaluated by pairwise differences in single-nucleotide polymorphisms (SNPs). FINDINGS: From May 11, 2013, to Aug 31, 2017, isolates that corresponded to 133 cases (73 clinical cases and 60 screening cases) were collected. Of 73 clinical cases, 66 (90%) cases involved isolates related to south Asian isolates, five (7%) cases were related to South American isolates, one (1%) case to African isolates, and one (1%) case to east Asian isolates. Most (60 [82%]) clinical cases were identified in New York and New Jersey; these isolates, although related to south Asian isolates, were genetically distinct. Genomic data corroborated five (7%) clinical cases in which patients probably acquired C auris through health-care exposures abroad. Among clinical and screening cases, the genetic diversity of C auris isolates within a person was similar to that within a facility during an outbreak (median SNP difference three SNPs, range 0-12). INTERPRETATION: Isolates of C auris in the USA were genetically related to those from four global regions, suggesting that C auris was introduced into the USA several times. The five travel-related cases are examples of how introductions can occur. Genetic diversity among isolates from the same patients, health-care facilities, and states indicates that there is local and ongoing transmission.

AB - BACKGROUND/OBJECTIVE: General practitioners (GPs) are pivotal in the organization of the entire post-stroke management system. This study aimed to examine the sequelae of chronic post-stroke patients and to assess whether the medical follow up organized by GPs is truly in accordance with current recommendations and patients' clinical needs. METHODS: This was an observational study including chronic post-stroke patients after a first stroke. Their post-stroke follow-ups (visits to GPs and specialist doctors) were compared with guidelines and with clinical needs as evaluated through a number of questionnaires. RESULTS: Overall, 53.2% of patients visited a neurologist as recommended and, although 49.4% had neuropsychiatric consequences, only 6.3% visited a psychiatrist. Similarly, while 34.2% had significant post-stroke disability, only 6.3% saw a rehabilitation physician. CONCLUSION: Taking into account not only cardiovascular prevention, but all post-stroke consequences, medical follow-ups as organized by GPs were not in accordance with recommendations and failed to take advantage of the currently available multidisciplinary resources required to improve patients' needs.

PMID- 30293881 TI - New findings in facial-onset sensory and motor neuronopathy (FOSMN) syndrome. AB - Facial-onset sensory and motor neuronopathy (FOSMN) syndrome represents a rare, slowly progressive, lower motor neuron disease with sensory compromise, involving mainly the face, bulbar region and upper limbs. However, non-motor symptoms and neurogenetic studies have rarely been evaluated in large case series. In the present study, 10 unrelated Brazilian patients with FOSMN syndrome underwent extensive clinical, laboratory, neurophysiological and neurogenetic assessment. Median age at symptom onset was 52.1 years, and men and women were equally affected. Patients presented with hemifacial or bilateral facial paresthesia and weakness, which evolved with dysphagia, dysphonia, and facial and tongue atrophy and, finally, a dropped-head, upper limb weakness and syringomyelia-like sensory disturbances in the upper limbs. All 10 patients showed chronic diffuse neurogenic compromise of bulbar, cervical and thoracic myotomes, and abnormal blink reflex tests. A positive family history of neurodegeneration was identified in six cases, and revealed pathogenic gene variants in three families (involving VCP, TARDBP and CHCHD10). Thus, our case series has revealed new findings regarding FOSMN syndrome: (i) its clinical course is not always benign, with poorer prognoses associated with dropped-head syndrome and early bulbar compromise; (ii) FOSMN syndrome may be part of a complex familial neurodegenerative spectrum; and (iii) a definite genetic basis may be observed in some cases. PMID- 30293882 TI - Myelin oligodendrocyte glycoprotein antibodies in neuromyelitis optica spectrum disorder. AB - Neuromyelitis optica spectrum disorder (NMOSD) is a severe inflammatory disease of the central nervous system characterized, in particular, by disabling episodes of optic neuritis and longitudinal extensive transverse myelitis. Its main pathogenic characteristic is the presence of anti-aquaporin-4 antibodies (AQP4 Abs) in the serum of affected patients. However, a proportion of patients with the typical NMOSD phenotype are, in fact, negative (seronegative) for AQP4-Abs and, within this category of patients, a proportion of them instead express antibodies to myelin oligodendrocyte glycoprotein (MOG-Abs). The presence of MOG Abs in the sera of seronegative NMOSD patients is more frequently associated with monophasic disease and moderate symptom severity, and also appears to predict a better outcome. The present report is a review of the clinical and immunological features of MOG-Ab-positive NMOSD. PMID- 30293883 TI - Acute brachial plexus lesion complicating a stun-gun assault. PMID- 30293884 TI - Clinical efficacy of tacrolimus for treating myasthenia gravis and its influence on lymphocyte subsets. AB - BACKGROUND: This study aimed to determine the clinical efficacy and effects of tacrolimus in treating myasthenia gravis (MG). METHODS: A total of 45 outpatients and inpatients were divided into a tacrolimus group (n=15) and non-tacrolimus group (n=30): those in the former group were treated with 3mg/day of tacrolimus for 24 weeks, while those in the latter (control) group took other immunosuppressants (prednisone, azathioprine combined with prednisone). Each group was evaluated at weeks 4, 8, 12, 16, 20 and 24 by Myasthenia Gravis Foundation of America Quantitative Myasthenia Gravis (MGFA-QMG) Test, activities of daily living (ADL) profiles, and manual muscle (MMT) and fatigue tests. Dynamic changes in CD4+CD25+high cells were tested by flow cytometry. Inflammatory cytokines were also evaluated in the tacrolimus group. RESULTS: Efficacy index scores decreased significantly compared with baseline at every test week in both groups (P<0.01), although improvements were more evident with than without tacrolimus treatment (F=9.312, P<0.01 vs. F=24.551, P<0.01 and F=10.710, P<0.01). At week 24, peripheral blood CD4+CD25+high T cells with tacrolimus decreased significantly (P<0.01), but increased significantly without tacrolimus (P<0.01). During treatment, CD19+BAFF-R B cells in peripheral blood decreased in both groups (P<0.05). Interferon (IFN)-gamma concentrations in peripheral blood also diminished significantly with tacrolimus (P<0.01). CONCLUSION: A relatively low dose of tacrolimus can affect multiple immune-system targets and, thus, can treat MG effectively in terms of both clinical symptoms and immunological responses. PMID- 30293885 TI - Danish Trends in Major Amputation After Vascular Reconstruction in Patients With Peripheral Arterial Disease 2002-2014. AB - INTRODUCTION: Contemporary information on major amputations after revascularisation in Denmark is sparse. This population based national study aimed to determine outcomes following revascularisation for PAD and to identify predictors of major amputation after revascularisation, including geographical variation. METHODS: Data on patients with PAD undergoing revascularisation (endovascular, open, and hybrid procedures) from 2002 to 2014 were obtained from the Danish Vascular Registry and linked with information from population based healthcare and administrative databases. Cox proportional hazards regression was used to assess the relationship between major amputation and the various associated factors. RESULTS: In all 25,982 first time vascular reconstructions for PAD were performed between 2002 and 2014 and major amputations were performed in 2883 (11.1%) of the patients. The total number of revascularisations increased up to 2010 and thereafter numbers decreased slightly. A trend towards endovascular revascularisation as first time revascularisation was seen (36.6% in 2002 vs. 59.0% in 2014, p < .001). Median time from first revascularisation to major amputation was 4.66 months (range 0.03-146.88 months), and 63.1% of major amputations were performed within one year following revascularisation. No change in the number of amputations performed within one year after revascularisation was found during the study (p = .251). The strongest predictor for major amputations was ulcers/gangrene (HR 8.06, CI 7.11-9.13, p < .001) at the time of revascularisation. Geographic variation for intensity of revascularisation was observed and geographic differences in amputation free survival for patients with intermittent claudication and ulcers/gangrene were found. CONCLUSION: Although more patients with PAD undergo revascularisation, one in 10 still ends up with a major amputation of the lower limb. The risk of amputation was highly associated with the severity of the vascular disease at the time of revascularisation, with ulcers/gangrene as the strongest predictor. Geographic differences in vascular treatment intensity were found, but these failed to explain the differences in risk of major amputation after revascularisation across catchment areas.

PMID- 30293887 TI - Long-term Survival and Risk Analysis in 136 Consecutive Patients With Type B Aortic Dissection Presenting to a Single Centre Over an 11 Year Period. AB - OBJECTIVES: To evaluate, in patients with acute type B aortic dissection, the results of medical and endovascular treatment in a large single centre experience and to investigate the clinical and imaging features on presentation that relate to poor outcome. METHODS: This was a retrospective analysis of prospectively collected clinical and CT imaging data. Consecutive patients (136) with acute type B aortic dissection were included in the study over an 11 year period. The characteristics of patients receiving endovascular (complicated) or medical treatment (uncomplicated) were compared. Kaplan-Meier estimators were used to estimate cumulative overall survival and survival free of aortic events. Factors associated with overall and aortic event free survival were also explored using Cox proportional hazards models. RESULTS: The mean follow up was 51 months (1 132), during which time 33 deaths and 48 aortic events occurred. At one and five years, overall survival was 94.0% and 74.8%, respectively, and freedom from aortic events was 75.6% and 58.7%. There was no difference in all cause survival and aortic event free survival at one and five years between the patients treated endovascularly and those receiving medical treatment alone. Risk analysis for aortic events demonstrated the maximum size of the proximal entry tear, the maximum thoracic aortic diameter, and the thoracic aortic false lumen maximum diameter to have a significant effect on the incidence of aortic events. CONCLUSIONS: Active management of patients with type B aortic dissection results in good long-term survival even in the presence of features traditionally associated with adverse outcomes. All patients require close lifetime surveillance as aortic events continue to occur during follow up even after endografting.

PMID- 30293889 TI - Correcting for Body Surface Area Identifies the True Prevalence of Abdominal Aortic Aneurysm in Screened Women. AB - OBJECTIVE/BACKGROUND: Recently, the prevalence of abdominal aortic aneurysm (AAA) using screening strategies based on elevated cardiovascular disease (CVD) risk was reported. AAA was defined as a diameter >=30 mm, with prevalence of 6.1% and 1.8% in men and women respectively, consistent with the widely reported AAA predominant prevalence in males. Given the obvious differences in body size between sexes this study aimed to re-evaluate the expanded CVD risk based AAA screening dataset to determine the effect of body size on sex specific AAA prevalence. METHODS: Absolute (26 and 30 mm) and relative (aortic size index [ASI] equals the maximum infrarenal aorta diameter (cm) divided by body surface area (m2), ASI >= 1.5) thresholds were used to assess targeted AAA screening groups (n = 4115) and compared with a self reported healthy elderly control group (n = 800). RESULTS: Male AAA prevalence was the same using either the 30 mm or ASI >=1.5 aneurysm definitions (5.7%). In females, AAA prevalence was significantly different between the 30 mm (2.4%) and ASI >= 1.5 (4.5%) or the 26 mm (4.4%) thresholds. CONCLUSION: The results suggest the purported male predominance in AAA prevalence is primarily an artefact of body size differences. When aortic size is adjusted for body surface area there is only a modest sex difference in AAA prevalence. This observation has potential implications in the context of the ongoing discussion regarding AAA screening in women. PMID- 30293890 TI - [Angiomatoid fibrous histiocytoma of the radial pulse groove]. AB - BACKGROUND: Angiomatoid fibrous histiocytoma (AFH) is a slowly progressing rare soft-tissue tumour of moderate malignant potential. It is most commonly seen in children and young adults. Clinically, the lesion is easily confused with a haematoma or soft-tissue haemangioma, and the radiological aspects are not specific. PATIENTS AND METHODS: A 16-year-old male patient presented with a nodular lesion situated very close to the right radial artery, vein and nerve and which had been developing for several years. Surgical resection was carried out with sparing of vasculonervous and functional structures. Histological examination revealed a tumour of plurinodular architecture, surrounded by a fibrous pseudocapsule consisting of histiocytoid or fusiform cells in short bundles associated with a mononuclear inflammatory reaction of nodular architecture. The tumour cells expressed the following immunomarkers: desmin, smooth muscle actin, CD99, and epithelial membrane antigen. Fusion transcript EWSR1-ATF1 was found. DISCUSSION: In this case, as occurs in the literature, a diagnosis of AFH was not made on clinical examination or imaging. The enlarged excision normally recommended was greatly restricted in our patient due to the complex localization of the lesion, which was in contact with major anatomical structures. The diagnosis was based on histological examination of the surgical excision and identification of the fusion gene. Long-term follow-up is required to detect local recurrence or metastasis. Management is decided in multidisciplinary meetings. PMID- 30293891 TI - Indeterminate biliary strictures differential diagnosis: Back to the future. PMID- 30293892 TI - Which heart rate variability index is an independent predictor of mortality in cirrhosis. AB - BACKGROUND: Liver cirrhosis is associated with reduced heart rate variability (HRV), which indicates impaired integrity of cardiovascular control in this patient population. There are several different indices for HRV quantification. The present study was designed to: 1) determine which of the HRV indices is best at predicting mortality in patients with cirrhosis; 2) verify if such ability to predict mortality is independent of the severity of hepatic failure. METHODS: Ten minutes electrocardiogram was recorded in 74 patients with cirrhosis. Heart rate fluctuations were quantified using statistical, geometrical and non-linear analysis. The patients were followed-up for 18 months and information was collected on the occurrence of death/liver transplantation. RESULTS: During the follow-up period, 24 patients (32%) died or were transplanted for hepatic decompensation. Cox's regression analysis showed that SDNN (total HRV), cSDNN (corrected SDNN), SD1 (short-term HRV), SD2 (long-terms HRV) and spectral indices could predict survival in these patients. However, only SD2 and cSDNN were shown to be independent of MELD in predicting survival. The prognostic value of HRV indices was independent of age, gender, use of beta blockers, and the aetiology of liver disease. CONCLUSION: Two HRV indices were identified that could predict mortality in patients with cirrhosis, independently of MELD. These indices are potentially useful tools for survival prediction. PMID- 30293893 TI - Ghrelin transport across the blood-brain barrier can occur independently of the growth hormone secretagogue receptor. AB - OBJECTIVE: The blood-brain barrier (BBB) regulates the entry of substrates and peptides into the brain. Ghrelin is mainly produced in the stomach but exerts its actions in the central nervous system (CNS) by crossing the BBB. Once present in the CNS, ghrelin can act in the hypothalamus to regulate food intake, in the hippocampus to regulate neurogenesis, and in the olfactory bulb to regulate food seeking behavior. The goal of this study was to determine whether the primary signaling receptor for ghrelin, the growth hormone secretagogue receptor (GHSR), mediates the transport of ghrelin from blood to brain. METHODS: We utilized the sensitive and quantitative multiple-time regression analysis technique to determine the transport rate of mouse and human acyl ghrelin (AG) and desacyl ghrelin (DAG) in wildtype and Ghsr null mice. We also measured the regional distribution of these ghrelin peptides throughout the brain. Lastly, we characterized the transport characteristics of human DAG by measuring the stability in serum and brain, saturability of transport, and the complete transfer across the brain endothelial cell. RESULTS: We found the transport rate across the BBB of both forms of ghrelin, AG, and DAG, were not affected by the loss of GHSR. We did find differences in the transport rate between the two isoforms, with DAG being faster than AG; this was dependent on the species of ghrelin, human being faster than mouse. Lastly, based on the ubiquitous properties of ghrelin throughout the CNS, we looked at regional distribution of ghrelin uptake and found the highest levels of uptake in the olfactory bulb. CONCLUSIONS: The data presented here suggest that ghrelin transport can occur independently of the GHSR, and ghrelin uptake varies regionally throughout the brain. These findings better our understanding of the gut-brain communication and may lead to new understandings of ghrelin physiology. PMID- 30293894 TI - The regulation of insulin secretion via phosphoinositide-specific phospholipase Cbeta signaling. AB - Phospholipase Cbeta (PLCbeta) is a membrane-associated enzyme activated by membrane receptors, especially G-protein coupled receptors (GPCRs). It propagates intracellular signaling by mediating phospholipid metabolism and generating key second messengers, such as inositol triphosphate and diacylglycerol, leading to intracellular Ca2+ mobilization and activation of kinases, such as protein kinases C. In pancreatic beta-cells, PLCbeta-mediated signaling activated by various factors, such as free fatty acids and neuronal and hormonal ligands, has been confirmed as being involved in the regulation of insulin secretion, and PLCbetas have been regarded as essential mediators for augmenting insulin secretion. In this review, we describe the physiological function of PLCbetas in the regulation of glucose-stimulated insulin secretion and discuss emerging data on GPCR/PLCbeta signaling that is being developed as a target for the treatment of diabetes mellitus. PMID- 30293895 TI - Analysis of clinical characteristics and S gene sequences in chronic asymptomatic HBV carriers with low-level HBsAg. AB - BACKGROUND: During the natural hepatitis B virus (HBV) infection process, some infected subjects are characterized by a sustained low serum HBV surface antigen (HBsAg) expression level. Most members in this population are chronic asymptomatic HBV carriers (ASCs). To elucidate the mechanism underlying low-level HBsAg expression in ASCs, we sequenced the HBV S gene in these patients to reveal specific sequence characteristics. METHODS: Overall, 1308 cases of chronic ASCs were grouped according to their HBsAg serum expression levels (10 IU/mL). The clinical characteristics of the population were analysed in detail. The HBV S gene was sequenced from 276 ASC cases with low-level HBsAg expression. Additionally, 100 of 1032 ASC cases with high-level HBsAg expression were randomly selected for HBV S gene sequencing based on age matching according to the low-level HBsAg group. A comparative analysis was conducted with the HBV S gene sequences from ASCs with low HBsAg expression and the HBV reference S gene sequences from ASCs with high HBsAg expression. RESULTS: The population with low level HBsAg expression displayed the following primary clinical characteristics: mostly chronic asymptomatic HBV carriers, older age (mean age 55.09 years), HBsAg/anti-HBe/anti-HBc (core) positivity as the main serological pattern (97.1%), low HBV DNA replication (1.32 +/- 1.60 log10 IU/mL), a low HBV-DNA positive rate (45.65%) and primarily genotype B (82.54%) and serotype adw (84.13%). The comparative analysis of the HBV S gene sequences from ASCs with low level HBsAg showed significant mutations (including co-mutations) on both sides of the main hydrophilic region (MHR). CONCLUSION: Significant mutations in multiple regions and at multiple sites (including co-mutations) on both sides of the MHR may be one cause of the low HBsAg expression level in this population.

PMID- 30293898 TI - Late growth of infantile hemangiomas in children >3 years of age: A retrospective study. AB - BACKGROUND: The proliferative phase of infantile hemangiomas (IHs) is usually complete by 9 months of life. Late growth beyond age 3 years is rarely reported. OBJECTIVE: To describe the demographic and clinic characteristics of a cohort of patients with late growth of IH, defined as growth in a patient >3 years of age. METHODS: A multicenter, retrospective cohort study. RESULTS: In total, 59 patients, 85% of which were female, met the inclusion criteria. The mean first episode of late growth was 4.3 (range 3-8.5) years. Head and neck location (55/59; 93%) and presence of deep hemangioma (52/59; 88%) were common characteristics. Posterior fossa malformations, hemangiomas, arterial anomalies, cardiac defects, eye abnormalities (PHACE) syndrome was noted in 20 of 38 (53%) children with segmental facial IH. Systemic therapy (corticosteroid or beta blocker) was given during infancy in 58 of 59 (98%) and 24 of 59 (41%) received systemic therapy (beta-blockers) for late IH growth. LIMITATIONS: The retrospective nature and ascertainment by investigator recall are limitations of the study. CONCLUSION: Late IH growth can occur in children after 3 years of age. Risk factors include head and neck location, segmental morphology, and involvement of deep dermal/subcutaneous tissues. PMID- 30293900 TI - Variation of surgery clerkship grades in US medical schools. AB - BACKGROUND: Despite efforts at standardization, evaluation and reporting of clerkships remains highly variable. This study reviews the current spectrum of surgical clerkship grading. METHODS: Data were reviewed for every medical school from which an application was received to a single surgery residency program in 2017 and were evaluated for core surgical clerkship grading systems, distributions, and components. Fischer's exact tests and Wilcoxon-Mann-Whitney tests were used for analysis. RESULTS: 133 (49 private) schools were evaluated. Geographic distribution:34 Northeast, 50 South, 31 Midwest and 18 West. 120 reported grading tiers, with public schools (95%) more likely than private (80%) to report this (p = 0.02). The number of grading categories ranged from 2 to 11; 90% with 3-5. Over 25% of the schools gave >=40% of students the highest grade; median of 30% in the highest tier. CONCLUSIONS: Significant variation exists in core surgery clerkship grading between schools. Similarly, a sizeable difference exists in how grades are calculated and the reporting systems used. Standardizing grading schemes across medical schools would be beneficial. PMID- 30293899 TI - Hospitalized patients with stress hyperglycemia: incidence of diabetes and mortality on follow-up. AB - INTRODUCTION: The study objective was to estimate during post-discharge follow-up the incidence of diabetes and to ascertain mortality in hospitalized patients, classified during follow-up as having stress hyperglycemia (SH) or normoglycemia (NG) based on blood glucose levels. MATERIAL AND METHODS: A retrospective cohort of non-diabetic adults with SH (> 140mg/dl and HbA1c <6.5%) or NG (all blood glucose values <= 140mg/dl) was used. RESULTS: There were 3981 patients with NG and 884 with SH. During the observation period (median follow-up of 1.83 years), there were 255 cases of diabetes and 831 deaths. The cumulative incidence of diabetes per year was 1.59% (95% CI: 1.23-2.06) in patients with NG and 7.39% (95% CI: 5.70-9.56) in those with SH. SH was significantly associated to diabetes (crude HR 1.33, 95% CI: 1.13-1.73, p .025), even after adjusting for age and sex (adjusted HR 1.38, 95% CI 1.06-1.78, p .014). The mortality rate at one year was 10.07% (95% CI: 9.18-11.05) in NG patients and 13.24% (95% CI: 11.17-15.65) in SH patients. The sub-hazard ratio of developing diabetes considering death as a competitive event was 1.41 (95% CI 1.29-1.53, p <.001). CONCLUSIONS: SH is a risk factor for diabetes. There were no differences in mortality during follow-up, but death appears to be a competitive event in development of diabetes in this population. PMID- 30293901 TI - Circulating Thrombospondin-2 enhances prediction of malignant intraductal papillary mucinous neoplasm. AB - BACKGROUND: IPMNs are cystic pancreatic lesions with variable malignant potential. Thrombospondin-2 (THBS2)-an endogenous, anti-angiogenic matrix glycoprotein-may modulate tumor progression. We hypothesized that circulating levels of THBS2 could aid in preoperative prediction of malignant IPMN. METHODS: Preoperative serum/plasma samples were procured from patients undergoing surgery. Circulating levels of THBS2 were measured (enzyme-linked immunosorbent assay) and compared to surgical pathology IPMN dysplastic grade. RESULTS: 164 patients underwent THBS2 testing (100 Low/Moderate-IPMN; 64 High-Grade/Invasive-IPMN). Circulating THBS2 (mean +/- SD) was greater in High-Grade/Invasive-IPMN than Low/Moderate-grade IPMN (26.6 +/- 12.7 ng/mL vs. 20.4 +/- 8.2 ng/mL; P < 0.001). THBS2 (AUC = 0.65) out-performed CA19-9 (n = 144; AUC = 0.59) in predicting IPMN grade. The combination of THBS2, CA19-9, radiographic main-duct involvement, main duct diameter, age, sex, and BMI (AUC 0.82; n = 137) provided a good prediction model for IPMN grade. CONCLUSION: Circulating THBS2 is correlated with IPMN dysplasia grade. THBS2 alone did not strongly predict IPMN grade but rather strengthened prediction models for High-Grade/Invasive IPMN when combined with other clinical/biomarker data.

PMID- 30293904 TI - Tumor-associated Macrophage-derived Interleukin-23 Interlinks Kidney Cancer Glutamine Addiction with Immune Evasion. AB - BACKGROUND: Glutamine addiction is a hallmark of clear cell renal cell carcinoma (ccRCC); yet whether glutamine metabolism impacts local immune surveillance is unclear. This knowledge may yield novel immunotherapeutic opportunities. OBJECTIVE: To seek a potential therapeutic target in glutamine-addicted ccRCC. DESIGN, SETTING, AND PARTICIPANTS: Tumors from ccRCC patients from a Shanghai cohort and ccRCC tumor data from The Cancer Genome Atlas (TCGA) cohort were analyzed. In vivo and in vitro studies were conducted with fresh human ccRCC tumors and murine tumor cells. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Immune cell numbers and functions were analyzed by flow cytometry. Glutamine and cytokine concentrations were determined. Survival was compared between different subpopulations of patients using Kaplan-Meier and Cox regression analyses. RESULTS AND LIMITATIONS: We found that in ccRCC, high interleukin (IL)-23 expression was significantly associated with poor survival in both TCGA (overall survival [OS] hazard ratio [HR]=2.04, cancer-specific survival [CSS] HR=2.95; all p<0.001) and Shanghai (OS HR=2.07, CSS HR=3.92; all p<0.001) cohorts. IL-23 blockade prolongs the survival of tumor-bearing mice, promotes T-cell cytotoxicity in in vitro cultures of human ccRCC tumors, and augments the therapeutic benefits of anti-PD-1 antibodies. Mechanistically, glutamine consumption by ccRCC tumor cells results in the local deprivation of extracellular glutamine, which induces IL-23 secretion by tumor-infiltrating macrophages via the activation of hypoxia-inducible factor 1alpha (HIF1alpha). IL 23 activates regulatory T-cell proliferation and promotes IL-10 and transforming growth factor beta expression, thereby suppressing tumor cell killing by cytotoxic lymphocytes. The positive correlations between glutamine metabolism, IL 23 levels, and Treg responses are confirmed in both TCGA cohort and tumors from Shanghai ccRCC patients. Study limitations include the unclear impacts of glutamine deprivation and IL-23 on other immune cells. CONCLUSIONS: Macrophage secreted IL-23 enhanced Treg functions in glutamine-addicted tumors; thus, IL-23 is a promising target for immunotherapy in ccRCC. PATIENT SUMMARY: In this study, we analyzed the immune components in glutamine-addicted clear cell renal cell carcinoma (ccRCC) tumors from two patient cohorts and conducted both in vitro and in vivo studies. We found that ccRCC tumor cell-intrinsic glutamine metabolism orchestrates immune evasion via interleukin (IL)-23, and IL-23-high patients had significantly poorer survival than IL-23-low patients. IL-23 should thus be considered a therapeutic target in ccRCC, either alone or in combination with immune checkpoint inhibitors. PMID- 30293905 TI - Efficacy of Radium-223 in Bone-metastatic Castration-resistant Prostate Cancer with and Without Homologous Repair Gene Defects. AB - BACKGROUND: Pathogenic mutations in genes mediating homologous recombination (HR) DNA repair are present in 20-30% of men with metastatic castrate-resistant prostate cancer (mCRPC). Radium-223 is a bone-seeking alpha-emitter that induces double-strand DNA breaks, thereby killing cancer cells in the bone microenvironment. OBJECTIVE: To evaluate the potential impact of germline or somatic HR-deficiency (HRD) mutations on radium-223 efficacy in mCRPC with bone metastasis. DESIGN, SETTING, AND PARTICIPANTS: This is a retrospective single institution study. Medical records of 190 mCRPC patients for whom germline and/or somatic DNA sequencing data were available were reviewed. Of these patients, 28 had received standard-of-care radium-223 at Johns Hopkins between February 2013 and February 2018. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Alkaline phosphatase (ALP) responses and time-to-ALP-progression were the coprimary endpoints. Prostate-specific antigen (PSA) responses, overall survival (OS), and time to next systemic therapy were also evaluated. RESULTS AND LIMITATIONS: Of the 28 patients included, 10 men (35.7%) had a germline/somatic HRD mutation (three in BRCA2, and one each in ATM, ATR, CHEK2, FANCG, FANCI, FANCL, and PALB2) and 18 (64.3%) did not. Men with HRD mutations (HRD+) had numerically lower ages (66 vs 73yr, p=0.25), more soft-tissue metastases (50% vs 38%, p=0.43), and higher baseline ALP levels (130 vs 108 U/l, p=0.84). Compared with HRD(-) men, HRD(+) patients showed greater ALP responses (80% vs 39%, p=0.04), longer time to ALP progression (median10.4 vs 5.8mo, hazard ratio [HR] 6.4, p=0.005), and a trend toward longer OS (median 36.9 vs 19.0mo, HR 3.3, p=0.11). PSA responses (0% vs 0%, p>0.99) and time to next systemic therapy (HR 1.5, p=0.39) were similar between the two groups. Results are limited by the retrospective nature of the analysis and the small sample size. CONCLUSIONS: In this exploratory study, bone metastatic CRPC patients with inactivating HRD mutations demonstrated significantly improved ALP responses and time to ALP progression. These results should motivate prospective validation of the "synthetic lethality" hypothesis between HRD mutations and radium-223 activity. PATIENT SUMMARY: In this report, we retrospectively examined outcomes to metastatic prostate cancer in patients with and without DNA repair mutations who received radium-223, a therapy that kills cancer cells by causing direct DNA damage. Our study suggested that patients who have inherited or acquired DNA repair gene mutations derived greater benefit from radium-223 when compared with patients without these mutations. We concluded that radium-223 might have an important role in this setting; however, prospective studies are needed to confirm whether DNA repair mutations truly make radium-223 work better or not. PMID- 30293906 TI - Systematic Review of Combination Drug Therapy for Non-neurogenic Lower Urinary Tract Symptoms. AB - CONTEXT: Several drugs are approved and available for the treatment of lower urinary tract symptoms (LUTS) in men and women. However, the vast majority of available data, upon which the approval and recommendation in guidelines are based, considered only the role of the monotherapies and did not evaluate possible combination therapies. OBJECTIVE: This systematic review analyzes the efficacy and adverse events of combination therapies for male and female LUTS. EVIDENCE ACQUISITION: A systematic literature search in the PubMed/Medline, Web of Science, and Cochrane databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement to identify clinical trials, randomized controlled trials, meta-analyses, and guidelines on male and female LUTS combination therapy published from March 2012 to December 2017 for men (in order to update a previous men-focused work) and from January 1988 to December 2017 for women. A total of 58 papers were identified. EVIDENCE SYNTHESIS: The most studied combination therapy for the treatment of male LUTS is the alpha1-adrenoceptor antagonist/5alpha-reductase inhibitor combination. This combination seems to be more efficacious in terms of several outcome variables, in particular in men who have moderate-to-severe LUTS and are at risk of disease progression. Also in terms of nocturia improvements, this combination is significantly more effective than the monotherapy. The other often studied combination treatment, in both male and female patients with LUTS, was the combination of antimuscarinics (in particular solifenacin) and mirabegron. This combination seems to be more effective in comparison with the monotherapies with respect to urinary incontinence and urgency urinary incontinence episodes and several other objective and subjective parameters, without relevant increase of adverse events. The combination of hormone therapy and antimuscarinics in women with LUTS does not seem to be useful. CONCLUSIONS: For the treatment of LUTS in men and women, combination therapy appears to be a promising option to optimize the efficacy of the available drugs for those who do not experience sufficient benefit with monotherapy. This add-on scenario offers the possibility to have a more tailored approach to the management of LUTS, always seeking the optimal balance between efficacy and tolerability for a given patient. PATIENT SUMMARY: Some combination of drugs may offer advantages over monotherapies for the treatment of voiding and storage complaints in men and women. PMID- 30293907 TI - Was it All Useless? PMID- 30293908 TI - External Beam Radiotherapy Increases the Risk of Bladder Cancer When Compared with Radical Prostatectomy in Patients Affected by Prostate Cancer: A Population based Analysis. AB - BACKGROUND: Long-term survival can be achieved in patients affected by localized prostate cancer (PCa) treated with either radical prostatectomy (RP) or external beam radiotherapy (EBRT). However, development of a second primary tumor is still poorly investigated. OBJECTIVE: To investigate the impact of RP and EBRT on subsequent risk of developing bladder (BCa) and/or rectal cancer (RCa) among PCa survivors. DESIGN, SETTING, AND PARTICIPANTS: A total of 84397 patients diagnosed with localized PCa, treated with RP or EBRT between 1988 and 2009, and older than 65 yr of age were identified in the Surveillance, Epidemiology, and End Results Medicare insurance program-linked database. Our primary objective was to investigate the effect of EBRT and RP on the second primary BCa and RCa incidence. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Multivariable competing risk regression analyses were performed to assess the risk of developing a second primary BCa or RCa. RESULTS AND LIMITATIONS: Of the 84397 individuals included in the study, 33252 (39%) were treated with RP and 51145 (61%) with EBRT. Median follow-up was 69 months, and follow-up periods for patients who did not develop BCa, RCa, or pelvic cancer were 68, 69, and 68 mo, respectively. A total of 1660 individuals developed pelvic tumors (1236 BCa and 432 RCa). The 5- and 10-yr cumulative BCa incidence rates were 0.75% (95% confidence interval [CI]: 0.64 0.85%) and 1.63% (95% CI: 1.45-1.80%) versus 1.26% (95% CI: 1.15-1.37%) and 2.34% (95% CI: 2.16-2.53%) for patients treated with RP versus EBRT, respectively. The 5- and 10-yr cumulative RCa incidence rates were 0.32% (95% CI: 0.25-0.39%) and 0.73% (95% CI: 0.61-0.85%) versus 0.36% (95% CI: 0.30-0.41%) and 0.69% (95% CI: 0.60-0.79%) for patients treated with RP versus EBRT, respectively. On multivariable competing risk regression analyses, treatment with EBRT was independently associated with the risk of developing a second primary BCa (hazard ratio: 1.35, CI: 1.18-1.55; p<0.001), but not RCa (p=0.4). Limitations include lack of information regarding the dose of radiotherapy and the retrospective nature with the implicit risk of selection bias. CONCLUSIONS: Patients treated with EBRT are at increased risk of developing a second primary BCa compared with those treated with RP. However, no differences were found considering RCa incidence in patients treated with RP or EBRT within the first 5 yr after primary therapy. These results need to be validated in a well-designed randomized prospective trial. PATIENT SUMMARY: We retrospectively analyzed the risk of developing a second primary bladder or rectal cancer during follow-up for patients treated with radical prostatectomy or external beam radiotherapy for a localized prostate cancer. We found that those treated with external beam radiotherapy are at an increased risk of developing a second primary bladder cancer tumor. PMID- 30293909 TI - Effects of vitamin D supplementation on musculoskeletal health: a systematic review, meta-analysis, and trial sequential analysis. AB - BACKGROUND: The effects of vitamin D on fractures, falls, and bone mineral density are uncertain, particularly for high vitamin D doses. We aimed to determine the effect of vitamin D supplementation on fractures, falls, and bone density. METHODS: In this systematic review, random-effects meta-analysis, and trial sequential analysis, we used findings from literature searches in previously published meta-analyses. We updated these findings by searching PubMed, Embase, and Cochrane Central on Sept 14, 2017, and Feb 26, 2018, using the search term "vitamin D" and additional keywords, without any language restrictions. We assessed randomised controlled trials of adults (>18 years) that compared vitamin D with untreated controls, placebo, or lower-dose vitamin D supplements. Trials with multiple interventions (eg, co-administered calcium and vitamin D) were eligible if the study groups differed only by use of vitamin D. We excluded trials of hydroxylated vitamin D analogues. Eligible studies included outcome data for total or hip fractures, falls, or bone mineral density measured at the lumbar spine, total hip, femoral neck, total body, or forearm. We extracted data about participant characteristics, study design, interventions, outcomes, funding sources, and conflicts of interest. The co-primary endpoints were participants with at least one fracture, at least one hip fracture, or at least one fall; we compared data for fractures and falls using relative risks with an intention-to-treat analysis using all available data. The secondary endpoints were the percentage change in bone mineral density from baseline at lumbar spine, total hip, femoral neck, total body, and forearm. FINDINGS: We identified 81 randomised controlled trials (n=53 537 participants) that reported fracture (n=42), falls (n=37), or bone mineral density (n=41). In pooled analyses, vitamin D had no effect on total fracture (36 trials; n=44 790, relative risk 1.00, 95% CI 0.93-1.07), hip fracture (20 trials; n=36 655, 1.11, 0.97-1.26), or falls (37 trials; n=34 144, 0.97, 0.93-1.02). Results were similar in randomised controlled trials of high-dose versus low-dose vitamin D and in subgroup analyses of randomised controlled trials using doses greater than 800 IU per day. In pooled analyses, there were no clinically relevant between-group differences in bone mineral density at any site (range -0.16% to 0.76% over 1-5 years). For total fracture and falls, the effect estimate lay within the futility boundary for relative risks of 15%, 10%, 7.5%, and 5% (total fracture only), suggesting that vitamin D supplementation does not reduce fractures or falls by these amounts. For hip fracture, at a 15% relative risk, the effect estimate lay between the futility boundary and the inferior boundary, meaning there is reliable evidence that vitamin D supplementation does not reduce hip fractures by this amount, but uncertainty remains as to whether it might increase hip fractures. The effect estimate lay within the futility boundary at thresholds of 0.5% for total hip, forearm, and total body bone mineral density, and 1.0% for lumbar spine and femoral neck, providing reliable evidence that vitamin D does not alter these outcomes by these amounts. INTERPRETATION: Our findings suggest that vitamin D supplementation does not prevent fractures or falls, or have clinically meaningful effects on bone mineral density. There were no differences between the effects of higher and lower doses of vitamin D. There is little justification to use vitamin D supplements to maintain or improve musculoskeletal health. This conclusion should be reflected in clinical guidelines. FUNDING: Health Research Council of New Zealand.

AB - Real-time functional magnetic resonance imaging (rtfMRI) allows visualisation of ongoing brain activity of the subject in the scanner. Denoising algorithms aim to rid acquired data of confounding effects, enhancing the blood oxygenation level dependent (BOLD) signal. Further image processing and analysis methods, like general linear models (GLM) or multivariate analysis, then present application specific information to the researcher. These processes are typically applied to regions of interest but, increasingly, rtfMRI techniques extract and classify whole brain functional networks and dynamics as correlates for brain states or behaviour, particularly in neuropsychiatric and neurocognitive disorders. We present Neu3CA-RT: a Matlab-based rtfMRI analysis framework aiming to advance scientific knowledge on real-time cognitive brain activity and to promote its translation into clinical practice. Design considerations are listed based on reviewing existing rtfMRI approaches. The toolbox integrates established SPM preprocessing routines, real-time GLM mapping of fMRI data to a basis set of spatial brain networks, correlation of activity with 50 behavioural profiles from the BrainMap database, and an intuitive user interface. The toolbox is demonstrated in a task-based experiment where a subject executes visual, auditory and motor tasks inside a scanner. In three out of four experiments, resulting behavioural profiles agreed with the expected brain state. PMID- 30293912 TI - [Clinical and pathological profile of the pleural malignant mesothelioma: A retrospective study about 30 cases]. AB - BACKGROUND: The malignant pleural mesothelioma (MPM) is a rare tumour usually associated to asbestos exposure. The delay between the exposure and the occurrence of the cancer can reach 40 years. This caused the pick of incidence described in many countries including Tunisia. The diagnosis is suspected based on clinical features but positive diagnosis is microscopic. Our aim was to describe the clinical and microscopic features of MPM through a single institution experience. PATIENTS AND METHODS: We conducted a retrospective study about 30 MPM diagnosed over a 20-year-period (1995-2015). We included only patients with complete records including clinical, radiologic and microscopic features. All the microscopic diagnoses were reviewed by 2 pathologists. A mean of 12 slides per case was reviewed. The diagnosis was based on the 2015 WHO classification. RESULTS: The mean age of the patients was 61 years, average 22 to 80 years. The sex ratio was 6,5. An asbetose exposition was reported in 21 cases. The most frequent symptoms was chest pain reported in 25 cases. Physical exam was normal in 9 cases. It revealed pleural syndorm in most patients (60 %). Imaging findings consisted mainly in diffuse pleural thickening in 17 cases. Twelve tumours were classified as stage I, 3 stage II, 14 stage III et 1 stage IV. Pleural biopsy was performed using needle in 18 cases, through thoracoscopy in 16 cases, thoracotomy in 3 cases and allowed the diagnosis in respectively 7 cases/18, 16 cases/16 and 3 cases/3. A lymph node biopsy was performed through mediastinoscopy in one case and yelded the diagnosis. The diagnosis was performed on surgical specimen in 2 patients: one bullectomy and one right upper lobectomy. The microscopic exam concluded to an EM in 17 cases, sarcomatoid mesothelioma (SM) in 4 cases and biphasic mesothelioma (BM) in 9 cases. Pan-cytokeratin antibody was used in all cases in association with 2 antibodies with positive diagnostic value and 2 antibodies with negative diagnostic value. It was repeated in 15 cases and the most used antibodies were the anti-calretinin and the TTF1. This was due to the lack of fixation in one case and in order to reach a quality criteria in the other cases. Surgical resection was possible in 2 patients. 15 patients were lost of view after a mean follow-up period of 3 months. Thirteen patients died before or during the follow-up. CONCLUSION: This work was about a Tunisian experience in the diagnosis and management of MPM. The major limits faced were the incomplete databases, the small number of patients included. Microsocpic positive diagnosis necessitates a degree of expertise and every laboratory has to determine the most valuable antibodies through its experience in order to optimize the diagnosis and to reduce the delay of diagnosis. PMID- 30293913 TI - Management of acute severe ulcerative colitis in Spain: A nationwide clinical practice survey. AB - INTRODUCTION: Ulcerative colitis (UC) is a chronic disease of the digestive tract and up to 20-30% of UC patients may suffer a severe flare-up during the course of the disease. Although there are national and international recommendations about its clinical management, there is not enough information about the treatment of acute severe UC in clinical practice. METHODS: An electronic and anonymous survey with 51 multiple-choice questions was performed among all the members of the Spanish Crohn's Disease and Ulcerative Colitis Working Group (GETECCU). RESULTS: Out of the 164 responders (20%), most were gastroenterologists (95%), with 59% from tertiary hospitals treating a median of 5 patients per year (IQR: 3-8) with a severe flare-up of ulcerative colitis. An endoscopic examination was routinely performed in 86% of patients (62% at admission). The most commonly used corticosteroid was methylprednisolone, usually at a dose of 60mg/day, and its response was assessed after a median of 3days (IQR: 3-5). Both in thiopurine naive and thiopurine-refractory patients, infliximab was the drug most frequently prescribed as rescue therapy. Half of responders (55%) had ever prescribed a first dose of infliximab higher than 5 mg/kg, and a higher proportion (73%) had ever prescribed an earlier dose of infliximab in the second or third infusion. CONCLUSIONS: Acute severe UC is generally managed according to current treatment guidelines in our setting. The rescue therapy most commonly prescribed is infliximab, and the use of intensified or accelerated regimens with this biological drug is not unusual. PMID- 30293914 TI - Elimination of hepatitis C virus infection from a hemodialysis unit and impact of treatment on the control of anemia. AB - INTRODUCTION: In the interferon era, the treatment of hepatitis C virus (HCV) infection in patients on haemodialysis (HD) was limited due to the significant number of treatment-related adverse events (AEs). Direct-acting antivirals (DAAs) have demonstrated their efficacy and safety in the treatment of HCV in patients with advanced chronic kidney disease on haemodialysis. The objective of the study was to evaluate the success in eliminating HCV infection from our dialysis unit using DAAs, and to assess the impact of HCV elimination on clinical and analytical outcomes. PATIENTS AND METHODS: This is a prospective, interventional, single-center study at Hospital Clinic de Barcelona. All HCV-RNA positive patients who received antiviral therapy with DAAs within a 3-year period (2014 2017) were analyzed (n=20). Data on virologic response, adverse events, and biochemical and hematological parameters during and after DAA therapy were analyzed. RESULTS: All patients achieved sustained virologic response (SVR) and only 40% of patients presented with mild AEs. None of the patients presented with HCV reinfection after a 1-year follow-up period, and thus HCV was eliminated from our HD unit. SVR was associated with a significant increase in hemoglobin and hematocrit, and a tendency toward the need for lower doses of iron supplementation with no changes in darbepoetin dose. CONCLUSION: HCV infection can be safely eliminated from HD units with the use of DAAs, preventing new infections in patients and healthcare staff. In the short term, the achievement of SVR is associated with an improvement in the control of anemia.

PMID- 30293916 TI - Dr. Hyacinthe Guilleminot and the first respiratory and cardiac synchronisation systems for obtaining radiological images. AB - In an era when it was not possible to achieve quality x-rays with short exposure times, the need to obtain chest images without movement led the French doctor Emre Hyacinthe Guilleminot to construct a machine that repeatedly emitted x-rays only when desired during the respiratory cycle. His aim was to create a satisfactory radiograph from multiple short bursts performed at the moment of inhalation or exhalation, based on Charles Bouchard's research on heart disease. He extended his idea to radiography of the heart, creating a system that enabled images to be obtained disassociating the phases of heartbeat. This article seeks to explain the basic functioning of these mechanisms, and to recover previous research papers that led to their creation. We will also retrieve biographical and personal data of the two people involved - one directly, the other indirectly - in these novel inventions.

PMID- 30293919 TI - The balance of sleep: Role of the vestibular sensory system. AB - The vestibular system encodes linear and angular head motion supporting numerous functions from gaze stabilization and postural control, to high-level cortical functions involving spatial cognition, including self-body perception, verticality perception, orientation, navigation and spatial memory. At the brainstem and mesencephalic levels, the vestibular organs also influence postural blood pressure regulation, bone density and muscle composition via specific vestibulo-sympathetic efferences and have been shown to act as a powerful synchronizer of circadian rhythms. Here, we review the evidence that sleep deprivation and sleep apnea syndrome alter vestibular-related oculo-motor and postural control, and that, in turn, vestibular pathologies induce sleep disturbances. We suggest that sleep-related neuroplasticity might serve the adaptation and compensation processes following vestibular lesions in patients. Interestingly, a reciprocal neuroanatomical route between the vestibular nuclei and the orexinergic neurons has been reported. While orexinergic modulation of the vestibular nuclei related to postural control has been suggested, we postulate that vestibular inputs might in turn influence the sleep-wake state switch, informing the brain about the daily quantity of motion.

AB - PURPOSE: Heterogeneous findings exist on antiretroviral therapy (ART) use in pregnancy and preterm delivery (PTD) or infants born small-for-gestational age (SGA). Whether reported differences may be explained by methods used to ascertain gestational age (GA) has not been explored. METHODS: We enrolled consecutive pregnant women attending a large primary care antenatal clinic in South Africa. Public-sector midwives assessed GA by last menstrual period (LMP) and symphysis fundal height (SFH). Separately, if clinical GA was less than 24 weeks, ultrasound (US) was performed by a research sonographer blinded to midwife assessments. In analysis, the impact of measurement error on the association between HIV/ART status and birth outcome by GA method was assessed, and factors associated with clinical GA underestimation or overestimation identified. RESULTS: In 1787 women included overall, estimated PTD incidence was 36% by LMP, 17% by SFH, and 11% by US. PTD risk was higher for HIV-infected than HIV uninfected women using US-GA (adjusted odds ratio [aOR] 1.95; 95% CI 1.10-3.46); for LMP/SFH-GA, the associations were smaller and not significant. These findings persisted after adjustment for age, parity, height, and previous PTD. PTD risk did not vary by timing of ART initiation (before or during pregnancy) for any method. Elevated BMI and older age were associated with decreased risk of underestimation by both LMP and SFH; HIV status and obesity were associated with increased risk of overestimation by SFH. There were no differences in SGA incidence across GA methods. CONCLUSIONS: Findings for an association between HIV/ART and birth outcomes are substantially influenced by GA assessment method. With growing public health interest in this association, future research efforts should seek to standardize optimal measures of gestation. PMID- 30293921 TI - In situ bioremediation of 1,2-dibromoethane (EDB) in groundwater to part-per trillion concentrations using cometabolism. AB - 1,2-Dibromoethane (ethylene dibromide; EDB) is a probable human carcinogen that was historically added to leaded gasoline as a scavenger to prevent the build-up of lead oxide deposits in engines. Studies indicate that EDB is present at thousands of past fuel spill sites above its stringent EPA Maximum Contaminant Level (MCL) of 0.05 MUg/L. There are currently no proven in situ options to enhance EDB degradation in groundwater to meet this requirement. Based on successful laboratory studies showing that ethane can be used as a primary substrate to stimulate the aerobic, cometabolic biodegradation of EDB to <0.015 MUg/L (Hatzinger et al., 2015), a groundwater recirculation system was installed at the FS-12 EDB plume on Joint Base Cape Cod (JBCC), MA to facilitate in situ treatment. Groundwater was taken from an existing extraction well, amended with ethane, oxygen, and inorganic nutrients and then recharged into the aquifer upgradient of the extraction well creating an in situ reactive zone. The concentrations of EDB, ethane, oxygen, and anions in groundwater were measured with time in a series of nested monitoring wells installed between the extraction and injection well. EDB concentrations in the six monitoring wells that were hydraulically well-connected to the pumping system declined from ~ 0.3 MUg/L (the average concentration in the recirculation cell after 3 months of operation without amendment addition) to <0.02 MUg/L during the 4-month amendment period, meeting both the federal MCL and the more stringent Massachusetts MCL (0.02 MUg/L). The data indicate that cometabolic treatment is a promising in situ technology for EDB, and that low regulatory levels can be achieved with this biological approach.

PMID- 30293923 TI - Quality of Life in Long-Term Testicular Cancer Survivors With Compensated Leydig Cell Dysfunction. AB - BACKGROUND: Compensated Leydig cell (LC) dysfunction, defined by elevated serum levels of luteinizing hormone (LH) in combination with normal total testosterone levels, is common in testicular cancer (TC) survivors. The association between this condition and quality of life is unknown. We aimed to clarify if TC survivors with compensated LC dysfunction have impaired quality of life. PATIENTS AND METHODS: In total, 147 long-term TC survivors were included. On the basis of a single measurement of testosterone and LH, compensated LC dysfunction was defined by age-adjusted levels of LH above normal range combined with testosterone levels within the normal range. Quality-of-life outcomes including sexual function, anxiety and depression, fatigue, and overall self-evaluated quality of life were compared between patients with and without compensated LC dysfunction with adjustment for age. RESULTS: In total, 60 TC survivors had compensated LC dysfunction and 87 TC survivors had normal LC function. TC survivors with compensated LC dysfunction had lower serum levels of total testosterone (11 vs. 13 nmol/L, P = .016). There were no significant differences in the investigated quality-of-life outcomes (anxiety, depression, sexual function, fatigue) between the 2 groups. CONCLUSION: Compensated LC dysfunction in TC survivors was not associated with symptoms of depression, anxiety, sexual dysfunction, fatigue, or impaired overall self-evaluated quality of life. Limitations include the few cases of symptoms of depression (n = 7). Our findings do not suggest that testosterone substitution is indicated in TC survivors with compensated LC dysfunction. PMID- 30293924 TI - The C-Reactive Protein to Albumin Ratio Predicts Acute Kidney Injury in Patients With ST-segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention. AB - BACKGROUND: The relationship between acute kidney injury (AKI) and C-reactive protein (CRP) and albumin has been previously demonstrated in patients with ST elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI). However, to our knowledge, CRP to albumin ratio (CAR), a newly introduced inflammation-based risk score, has not yet been studied. In this study, we aimed to investigate the possible relationship between the CAR and AKI. METHOD: A total of 815 consecutive STEMI patients treated with pPCI were reviewed. RESULTS: 110 (13.5%) patients developed AKI in the study population. The subjects were divided into two groups according to AKI development. The in-hospital mortality rate was higher in patients with AKI than those without AKI (15.5% vs. 1.3%; p<0.001). The patients with AKI had significantly higher mean value of CRP and CAR (0.29 [0.16-0.50] vs. 0.55 [0.37 1.05]; p<0.001) and lower mean levels of albumin than those without AKI. Age, diabetes mellitus, haematocrit, left ventricular ejection fraction, hypotension, and CAR (Odd's ratio [OR]2.307, 95% confidence interval [CI] 1.397-3.809, p=0.001) were independent predictors of AKI. CONCLUSION: The CAR may be a useful inflammation-based risk score to predict AKI development in STEMI patients treated with pPCI.

PMID- 30293926 TI - Monitoring early developed low bone mineral density in HIV-infected patients by intact parathyroid hormone and circulating fibroblast growth factor 23. AB - BACKGROUND/PURPOSE: HIV-infected patients have a high prevalence of low bone mineral density (BMD), but BMD changes remain unclear. This cross-sectional retrospective observational study aimed to characterize the prevalence and associated factors of low BMD in HIV patients. METHODS: Between 1 January 2015 and 31 December 2016, all patients aged 20 years or greater who sought for HIV care were included. BMD was measured by dual-energy X-ray absorptiometry. Multivariable analyses of the association with HIV disease status, treatment and anthropometric parameters were performed. Circulating fibroblast growth factor 23 and intact parathyroid hormone were measured. RESULTS: A total of 137 patients was included; their median age was 39 years old; 97.8% were treated with combination antiretroviral therapy (cART); Body mass index (BMI) was 21.97 kg/m2. Sixty-one patients (44.5%) showed low BMD (osteopenia and osteoporosis) based on the WHO criteria. The median BMD was -0.80 g/cm2 (IQR, -1.5 to -0.2). The prevalence rate of low BMD was 37% in those who were aged 20-29 years, 45.2% in those who were aged 30-39 years, 45.2% in those who were aged 40-49 years, 45.8% in those who were aged 50-59 years, and 53.8% in those who were aged ?60 years. More than half of patients (50.4%, 69/137) were younger than 40 years. Compared with normal BMD group, the low BMD group has a higher proportion of secondary hyperparathyroidism (18.0% vs 5.3%, p: 0.026) and a lower median C-terminal FGF23 level (48.92 vs 62.61 pg/ml, p: 0.008). Univariate and multivariate analyses of the factors associated with low BMD. We found that only serum intact-parathyroid hormone (iPTH) > 69 pg/ml (OR, 3.86; 95% CI, 1.14-13.09) was statistically significant associated with low BMD in multivariate analysis. CONCLUSIONS: This cohort-based survey showed a high prevalence of low BMD among HIV-infected adults which included young-age patient in an university hospital. Secondary hyperparathyroidism was significantly associated with low BMD. There was no association between FGF23 and low BMD. PMID- 30293927 TI - Outcome and prognostic factors of patients treated in the intensive care unit for carbon monoxide poisoning. AB - BACKGROUND: Carbon monoxide (CO), a colorless and odorless gas, is one of the common causes of poisoning-related deaths worldwide. CO poisoning can result in hypoxic brain damage and death, but intensive care can improve the likely outcome for critically ill patients. However, there is a paucity of clinical data regarding the prognostic factors and association between organ dysfunction and clinical outcome of patients treated for CO poisoning in the intensive care unit (ICU). METHODS: We performed a retrospective study of patients admitted to a university affiliated hospital ICU between July 2001 and December 2010 following CO poisoning. Outcomes were survival to ICU discharge and to hospital discharge. RESULTS: Seven hundred and eighty-seven patients were admitted to the university hospital following CO poisoning, of which 140 (17.8%) were admitted to the hospital ICU. The overall mortality rate of the patients admitted to the ICU was 14.3% (20/140). Univariate analysis indicated that non-surviving patients with CO poisoning were more likely to have initial blood carboxyhemoglobin (COHb) level > 30%, shock, acute respiratory failure, Acute Physiology and Chronic Health Evaluation II (APACHE II) score >= 25, Glasgow coma scale (GCS) score of 3, acute renal failure, dysfunction or failure of more than 3 organs, low blood pH, low HCO3- level, high potassium level, and high glucose level. They were also more likely to have not received hyperbaric oxygen (HBO) intervention. Multivariate logistical regression analysis indicated that the mortality rate of patients treated in the ICU for CO poisoning was higher if their initial APACHE II score was >=25, GCS was 3, and more than 3 organs were dysfunctional. Moreover, HBO intervention in ICU significantly decreased patients' risk of mortality due to CO poisoning. CONCLUSION: In conclusion, we observed that APACHE II score >25, GCS 3, and dysfunction of more than 3 organ systems on admission to emergency department was associated with a significant mortality risk in patients treated in the ICU for CO poisoning. Moreover, HBO therapy could reduce the risk of mortality in patients with CO poisoning in ICU. PMID- 30293928 TI - Early percutaneous cholecystostomy versus antibiotic treatment for mild and moderate acute cholecystitis: A retrospective cohort study. AB - BACKGROUND: Percutaneous cholecystostomy (PC) is an effective treatment for severe acute cholecystitis (AC). Guidelines recommend PC as rescue therapy for patients with mild or moderate AC who do not receive emergent cholecystectomy. This study aims to investigate whether PC could be a first-line treatment for these patients. METHODS: Adult patients admitted through the emergency department between October 2004 and December 2013 were retrospectively reviewed. Patients with mild or moderate AC who did not undergo emergent cholecystectomy were included. Early PC was defined as a PC tube inserted within 24 h of diagnosis. The outcomes were compared between patients who received antibiotics plus early PC (early PC group) and those who received antibiotic treatment alone (antibiotic group). RESULTS: A total of 698 patients were included. The mean age was 63.4 years. There were 171 patients in the early PC group and 527 patients in the antibiotic group. Multivariable logistic regression analyses indicated that early PC was significantly associated with a decreased rate of prolonged fever (odds ratio [OR], 0.31; 95% confidence interval [CI], 0.16-0.57; p < 0.001). Early PC also correlated with both increased short-term (OR, 15.95; 95% CI, 5.73-44.38; p < 0.001) and long-term treatment success (OR, 4.27; 95% CI, 2.55-7.15; p < 0.001). CONCLUSION: For patients with mild/moderate AC without emergent cholecystectomy, early PC might expedite sepsis resolution and improve the treatment success rate compared with antibiotic treatment alone. This result should be deemed as hypothesis-generating and should be examined in a randomized controlled trial. PMID- 30293929 TI - Short-term heart rate variability as a predictor of long-term survival in patients with chronic hemodialysis: A prospective cohort study. AB - BACKGROUND: Heart rate variability (HRV), a non-invasive measurement of the sympathetic-vagal balance, has been demonstrated as a predictor of long-term survival in various patient populations. However, its predictive value in patients with end-stage renal disease (ESRD) has not been evaluated in a long term follow-up study. METHODS: Prospective data collected for 41 patients with chronic hemodialysis (age 59 +/- 10 years, men 51.3%, diabetes mellitus 31%, and duration of dialysis 64 +/- 50 months) who underwent a 5-minute electrocardiogram (ECG) recording as a baseline for frequency domain HRV analysis. RESULTS: During a median follow-up of 150.2 months from 2003 to 2014, 15 (35.7%) patients died (3 due to cardiac causes and 12 due to non-cardiac causes). The Cox proportional hazards model suggested that the low frequency versus high frequency signal (LF/HF) of a high ratio for the HRV and diabetes mellitus were two independent predictors of mortality (hazard ratios 3.028 and 3.494; p = 0.033 and 0.022, respectively). Less reduction in MAP during dialysis showed borderline significance of long-term survival than those with larger drop (p = 0.058). CONCLUSION: A short ECG recording and an analysis of the frequency domain of the HRV is clinically predictive of the long-term survival of patients with chronic hemodialysis. PMID- 30293930 TI - Exploring the half-life of glyphosate in human urine samples. AB - BACKGROUND: The International Agency for Research on Cancer (IARC) has recently classified glyphosate as a Group 2A 'probably carcinogenic to humans'. Due to this carcinogenic classification and resulting international debate, there is an increased demand for studies evaluating human health effects from glyphosate exposures. There is currently limited information on human exposures to glyphosate and a paucity of data regarding glyphosate's biological half-life in humans. OBJECTIVE: This study aims to estimate the human half-life of glyphosate from human urine samples collected from amenity horticulture workers using glyphosate based pesticide products. METHODS: Full void urine spot samples were collected over a period of approximately 24 h for eight work tasks involving seven workers. The elimination time and estimation of the half-life of glyphosate using three different measurement metrics: the unadjusted glyphosate concentrations, creatinine corrected concentrations and by using Urinary Excretion Rates (UER) (MUg L-1, MUmol/mol creatinine and UER MUg L-1) was calculated by summary and linear interpolation using regression analysis. RESULTS: This study estimates the human biological half-life of glyphosate as approximately 5 1/2, 10 and 7 1/4 hours for unadjusted samples, creatinine corrected concentrations and by using UER (MUg L-1, MUmol/mol creatinine, UER MUg L-1), respectively. The approximated glyphosate half-life calculations seem to have less variability when using the UER compared to the other measuring metrics. CONCLUSION: This study provides new information on the elimination rate of glyphosate and an approximate biological half-life range for humans. This information can help optimise the design of sampling strategies, as well as assisting in the interpretation of results for human biomonitoring studies involving this active ingredient. The data could also contribute to the development or refinement of Physiologically Based PharmacoKinetic (PBPK) models for glyphosate. PMID- 30293931 TI - Safety, tolerability, and effectiveness of oral zonisamide therapy in comparison with intramuscular adrenocorticotropic hormone therapy in infants with West syndrome. AB - West syndrome is a distinct, infantile onset, epileptic encephalopathy, associated with poor neurodevelopmental outcome. The present study was designed as a randomized, open-label, pilot study to evaluate the safety, feasibility, and effectiveness of oral zonisamide therapy in comparison with adrenocorticotropic hormone therapy in infants with West syndrome. Thirty infants with West syndrome were randomized to receive treatment with either synthetic, intramuscular adrenocorticotropic hormone (30-60 IU) or oral zonisamide (4-25 mg/kg/day). The study participants had a long treatment lag and preponderance of male sex (90%). The primary effectiveness outcome measure was the cessation of epileptic spasms at 2 weeks of initiation of therapy and persistent till 6 weeks as per West Delphi consensus statement recommendations. Comparison of efficacies of zonisamide versus adrenocorticotropic hormone was as following: the cessation of epileptic spasms (27% vs. 40%, p = 0.70), resolution of hypsarrhythmia at 14 days (20% vs. 33%, p = 0.68) and resolution of hypsarrhythmia at 6 weeks (36% vs. 71%, p = 0.14). Overall, the study observed a poor efficacy of both adrenocorticotropic hormone and zonisamide therapy, which is probably due to long treatment lag and a high proportion of structural aetiology. However, oral zonisamide appeared to be safe and tolerable in the study. PMID- 30293932 TI - Prediction of lowest nocturnal blood glucose level based on self-monitoring of blood glucose in Japanese patients with type 2 diabetes. AB - AIMS: Continuous glucose monitoring (CGM) is not available for all patients with type 2 diabetes (T2D) at risk of nocturnal hypoglycemia (NH). This study was performed to predict the lowest nocturnal blood glucose (LNBG) levels. METHODS: An LNBG prediction formula was developed by multivariate analysis using the data including self-monitoring of blood glucose from a formula making (FM) group of 29 insulin-treated T2D patients with CGM. The validity of the formula was assessed by nonparametric regression analysis of actual and predicted values in a formula validation group consisting of 21 other insulin-treated patients. The clinical impact on prediction was evaluated using a Parkes error grid. RESULTS: In the FM group with a median age of 64.0, the following formula was established: Predicted LNBG (mg/dL) = 127.4-0.836 * Age (y) + 0.119 * Self-monitored fasting blood glucose (mg/dL) + 0.717 * Basal insulin dose (U/day) (standard error of calibration 17.2 mg/dL). Based on the validation results, standard error of prediction was 31.0 mg/dL. All predicted values fell within zones A (no effect on clinical action) and B (little or no effect on clinical outcome) on the grid. CONCLUSIONS: LNBG could be predicted, and may be helpful for NH prevention. PMID- 30293933 TI - Relationship between physicians' death anxiety and medical communication and decision-making: A systematic review. AB - OBJECTIVE: To examine the relationship between physicians' death anxiety and medical communication and decision-making. It was hypothesized that physicians' death anxiety may lead to the avoidance of end-of-life conversations and a preference for life-prolonging treatments. METHODS: PubMed and PsycInfo were systematically searched for empirical studies on the relation between physicians' death anxiety and medical communication and decision-making. RESULTS: This review included five quantitative and two qualitative studies (N = 7). Over 38 relations between death anxiety and communication were investigated, five were in line with and one contradicted our hypothesis. Physicians' death anxiety seemes to make end of-life communication more difficult. Over 40 relations between death anxiety and decision-making were investigated, three were in line with and two contradicted the hypothesis. Death anxiety seemes related to physicians' guilt or doubt after a patient's death. CONCLUSIONS: There was insufficient evidence to confirm that death anxiety is related to more avoidant communication or decision-making. However, death anxiety does seem to make end-of-life communication and decision making more difficult for physicians. PRACTICE IMPLICATIONS: Education focused on death and dying and physicians' emotions in medical practice may improve the perceived ease with which physicians care for patients at the end of life. PMID- 30293934 TI - Sociodemographic and clinical correlates of key outcomes from a Mobile Insulin Titration Intervention (MITI) for medically underserved patients. AB - BACKGROUND: Insulin titration is typically done face-to-face with a clinician; however, this can be a burden for patients due to logistical issues associated with in-person clinical care. The Mobile Insulin Titration Intervention (MITI) used basic cell phone technology including text messages and phone calls to help patients with diabetes find their optimal basal insulin dose (OID). OBJECTIVE: To evaluate sociodemographic and clinical correlates of reaching OID, text message response rate, and days needed to reach OID. METHODS: Primary care providers referred patients to MITI and nurses delivered the program. Three multivariable regression models quantified relationships between various correlates and primary outcomes. RESULTS: The sample included 113 patients from 2 ambulatory clinics, with a mean age of 50 years (SD = 10), 45% female, 79% Hispanic, 43% unemployed, and 46% uninsured. In regression models, baseline fasting blood glucose (FBG) was negatively associated with odds of reaching OID and 100% text responses, and positively associated with days to reach OID, p < .05). CONCLUSIONS: Patients with higher baseline FBG levels were less successful across outcomes and may need additional supports in future mHealth diabetes programs. PRACTICAL IMPLICATIONS: Basic cell phone technology can be used to adjust patients' insulin remotely, thereby reducing logistical barriers to care. PMID- 30293935 TI - Preferences for surrogate designation and decision-making process in older versus younger adults with cancer: A comparative cross-sectional study. AB - OBJECTIVE: To compare the preferences of older (>=70 years old) versus younger (<70 years old) cancer patients regarding surrogate designation and decision making. METHODS: A cross-sectional survey. Patient characteristics and information about surrogacy and involvement in decision making were collected. Associations between patient characteristics and preferences were examined. RESULTS: The study included 130 patients aged >=70 years (mean age 80 years) and 102 patients aged <70 years (mean age 55) and. Factors independently associated with surrogate knowledge (66%): younger age, more children living nearby, high income; factors associated with having already designated a surrogate (62%): younger age, decreased number of daily medications; factors associated with designating a surrogate after questionnaire administration (40%): low education, metastasis. Patients requiring an informed consent for any intervention was associated with older age (adjusted OR [aOR]per year = 1.04[95% confidence interval 1.00-1.08]), not living alone (aOR = 2.52[1.00-6.36]), and having children (aOR = 4.49[1.13-17.81]). CONCLUSION: All cancer patients, wanted to be fully informed and 72% wanted to be involved in medical decisions. Preferences for decision control vary between age groups, depending on family members' presence and living alone. PRACTICE IMPLICATIONS: Sharing complete and clear information should be an important key in the process of cancer patients' care, regardless of patient age. PMID- 30293936 TI - Autosomal dominant hypercholesterolemia in Catalonia: Correspondence between clinical-biochemical and genetic diagnostics in 967 patients studied in a multicenter clinical setting. AB - BACKGROUND: Autosomal dominant hypercholesterolemia (ADH) is associated with mutations in the low-density lipoprotein (LDL) receptor (LDLR), apolipoprotein B (APOB), and proprotein convertase subtilisin/kexin 9 (PCSK9) genes, and it is estimated to be greatly underdiagnosed. The most cost-effective strategy for increasing ADH diagnosis is a cascade screening from mutation-positive probands. OBJECTIVE: The objective of this study was to evaluate the results from 2008 to 2016 of ADH genetic analysis performed in our clinical laboratory, serving most lipid units of Catalonia, a Spanish region with approximately 7.5 million inhabitants. METHODS: After the application of the Dutch Lipid Clinic Network (DLCN) clinical diagnostic score for ADH, this information and blood or saliva from 23 different lipid clinic units were investigated in our laboratory. DNA was screened for mutations in LDLR, APOB, and PCSK9, using the DNA-array LIPOchip, the next-generation sequencing SEQPRO LIPO RS platform, and multiplex ligation dependent probe amplification (MLPA). The Simon Broome Register Group (SBRG) criteria was calculated and analyzed for comparative purposes. RESULTS: A total of 967 unrelated samples were analyzed. From this, 158 pathogenic variants were detected in 356 patients. The main components of the DLCN criteria associated with the presence of mutation were plasma LDL cholesterol (LDLc), age, and the presence of tendinous xanthomata. The contribution of family history to the diagnosis was lower than in other studies. DLCN and SBRG were similarly useful for predicting the presence of mutation. CONCLUSION: In a real clinical practice, multicenter setting in Catalonia, the percentage of positive genetic diagnosis in patients potentially affected by ADH was 38.6%. The DLCN showed a relatively low capacity to predict mutation detection but a higher one for ruling out mutation. PMID- 30293937 TI - Short- and long-term association of lipid-lowering drug treatment and cardiovascular disease by estimated absolute risk in the Second Australian National Blood Pressure study. AB - BACKGROUND: There is currently insufficient evidence to support the use of lipid lowering drug treatment (LLT) for primary prevention of cardiovascular disease (CVD) in the elderly. OBJECTIVES: We examined the relationship of early initiation of LLT with short- and long-term all-cause and CVD mortality in persons older than 65 years in this post hoc study from the Second Australian National Blood Pressure study (ANBP2). METHODS: This was an in- and post-trial observational study. About 4257 hypertensive participants aged 65 to 84 years within Australian family practices were randomized to an angiotensin-converting enzyme inhibitor or a diuretic treatment group. After excluding participants with a prior history of CVD, the cohort was stratified into "LLT" and "no LLT" subgroups based on LLT status at randomization. RESULTS: At randomization, the participants had a mean age of 72 years, average blood pressure of 168/91 mm Hg and estimated 5-year CVD risk of 18.7 +/- 8.3%. In the overall study population, the association of LLT with long-term (11-years) all-cause and non-CVD mortality was significant (hazard ratio [HR] 0.78 [95% confidence interval {CI} 0.66-0.92, P = .003] and HR 0.70 [95% CI 0.54-0.90, P = .006], respectively). Magnitudes of the association of LLT with long-term mortality and the association with short term mortality were similar; however, no statistically significant association with short-term mortality was observed. In the subgroup analysis by baseline 5 year CVD risk, LLT participants in the highest risk tertile had a substantially lower relative risk for short-term all-cause mortality (HR 0.31, 95% CI 0.13 0.71, P for interaction .02) compared to those with lower estimated CVD risk. All analyses were adjusted for baseline and in-trial characteristics. CONCLUSION: Our study showed a strong association between LLT and reduced long-term all-cause mortality. Thus, our findings support recommendations of the use of LLT in patients over 65 years, particularly those with high CVD risk who were more likely to obtain additional benefits in the short term. The findings also suggested that mortality benefits of LLT for the elderly may take longer to become evident.

However, most proteins in the human proteome lack small-molecule probes, including the large class of non-catalytic transmembrane receptors, such as death receptors. We hypothesized that small molecules targeting the interfaces between transmembrane domains (TMDs) in receptor complexes may induce conformational changes that alter receptor function. Applying this concept in a screening assay, we identified a compound targeting the TMD of death receptor p75NTR that induced profound conformational changes and receptor activity. The compound triggered apoptotic cell death dependent on p75NTR and JNK activity in neurons and melanoma cells, and inhibited tumor growth in a melanoma mouse model. Due to their small size and crucial role in receptor activation, TMDs represent attractive targets for small molecule manipulation of receptor function. PMID- 30293938 TI - ALDH1 Bio-activates Nifuroxazide to Eradicate ALDHHigh Melanoma-Initiating Cells. AB - 5-Nitrofurans are antibiotic pro-drugs that have potential as cancer therapeutics. Here, we show that 5-nitrofurans can be bio-activated by aldehyde dehydrogenase (ALDH) 1A1/1A3 enzymes that are highly expressed in a subpopulation of cancer-initiating (stem) cells. We discover that the 5-nitrofuran, nifuroxazide, is selective for bio-activation by ALDH1 isoforms over ALDH2, whereby it both oxidizes ALDH1 and is converted to cytotoxic metabolites in a two hit pro-drug mechanism. We show that ALDH1High melanoma cells are sensitive to nifuroxazide, while ALDH1A3 loss-of-function mutations confer drug resistance. In tumors, nifuroxazide targets ALDH1High melanoma subpopulations with the subsequent loss of melanoma-initiating cell potential. BRAF and MEK inhibitor therapy increases ALDH1 expression in patient melanomas, and effectively combines with nifuroxazide in melanoma cell models. The selective eradication of ALDH1High cells by nifuroxazide-ALDH1 activation goes beyond current strategies based on inhibiting ALDH1 and provides a rational basis for the nifuroxazide mechanism of action in cancer. PMID- 30293940 TI - Decoding Transcriptome Dynamics of Genome-Encoded Polyadenylation and Autoregulation with Small-Molecule Modulators of Alternative Polyadenylation. AB - Alternative polyadenylation (APA) plays a critical role in regulating gene expression. However, the balance between genome-encoded APA processing and autoregulation by APA modulating RNA binding protein (RBP) factors is not well understood. We discovered two potent small-molecule modulators of APA (T4 and T5) that promote distal-to-proximal (DtoP) APA usage in multiple transcripts. Monotonically responsive APA events, induced by short exposure to T4 or T5, were defined in the transcriptome, allowing clear isolation of the genomic sequence features and RBP motifs associated with DtoP regulation. We found that longer vulnerable introns, enriched with distinctive A-rich motifs, were preferentially affected by DtoP APA, thus defining a core set of genes with genomically encoded DtoP regulation. Through APA response pattern and compound-small interfering RNA epistasis analysis of APA-associated RBP factors, we further demonstrated that DtoP APA usage is partly modulated by altered autoregulation of polyadenylate binding nuclear protein-1 signaling.

PMID- 30293942 TI - School Lunch Environmental Factors Impacting Fruit and Vegetable Consumption. AB - OBJECTIVE: Assess impact of school lunch environmental factors on fruit and vegetable (F&V) consumption in second and third grade students. DESIGN: Cross sectional observations in 1 school year. PARTICIPANTS: Students from 14 elementary schools in 4 New York City boroughs (n = 877 student-tray observations). MAIN OUTCOME MEASURE(S): Dependent variables were F&V consumption collected by visual observation. Independent variables included school lunch environmental factors, and individual-level and school-level demographics. ANALYSIS: Hierarchical linear modeling was used with F&V consumption as the outcome variable, and relevant independent variables included in each model. RESULTS: Slicing or precutting of fruits and having lunch after recess were positively associated (P < .05) with .163- and .080-cup higher fruit consumption across all students, respectively. Preplating of vegetables on lunch trays, having 2 or more vegetable options, and having lunch after recess were positively associated (P < .05) with .024-, .009-, and .007-cup higher vegetable consumption across all students, respectively. CONCLUSIONS AND IMPLICATIONS: Although there was a small increase in intake, results of the study support that some school lunch environmental factors affect children's F&V consumption, with some factors leading to more impactful increases than others. Slicing of fruits seems most promising in leading to greater fruit consumption and should be further tested. PMID- 30293943 TI - Resistance to molecularly targeted therapy in non-small-cell lung cancer. AB - The discovery of oncogenic driver gene mutations, including epidermal growth factor receptor (EGFR) mutation, anaplastic lymphoma kinase (ALK) fusion, ROS proto-oncogene 1 (ROS1) fusion, and ret proto-oncogene (RET) fusion, has led to the development of molecularly targeted therapy for non-small-cell lung cancer (NSCLC). This therapy has changed the standard of care for NSCLC. Despite the dramatic response to molecularly targeted therapy, almost all patients ultimately develop resistance to the drugs. To understand the mechanisms of resistance to molecularly targeted agents, it is essential to understand the molecular pathways of NSCLC. Here, we review the mechanisms of resistance to molecularly targeted therapy and discuss strategies to overcome drug resistance. PMID- 30293944 TI - Pemetrexed and carboplatin combination therapy followed by pemetrexed maintenance in Japanese patients with non-squamous non-small cell lung cancer: A subgroup analysis of elderly patients. AB - BACKGROUND: The combination of pemetrexed and carboplatin is commonly used for the treatment of advanced non-squamous non-small cell lung cancer (NSCLC), mainly because it is comparatively effective and less toxic than other platinum-doublet therapies. Using the JMII (JACAL) study, we report the efficacy and safety of this treatment followed by pemetrexed maintenance in the elderly population (>=70 years of age). METHODS: The JMII study was a multicenter, post-marketing study that assessed the efficacy and safety of carboplatin (AUC6) and pemetrexed (500 mg/m2, given on Day 1 of a 21-day cycle, 4 cycles) followed by pemetrexed (500 mg/m2) maintenance in advanced non-squamous NSCLC patients (n = 109). Retrospective subgroup analyses were performed in elderly patients aged >=70. RESULTS: The study includes younger (<70 years, n = 84) and elderly (>=70 years, n = 25) patients who received induction therapy. Median progression-free survival and overall survival from the start of the induction phase were 5.2 (95% CI: 3.5, 8.2) and 16.8 (95% CI: 10.3, NC) months for the elderly patients compared with 5.8 (95% CI: 4.3, 7.4) and 20.5 (95% CI: 16.7, NC) months for the younger patients, respectively. Grade 3/4 hematologic toxicities were more frequent in the elderly patients. Non-hematologic toxicities in the elderly patients were comparable to those in younger patients. Dose reduction was more common in the elderly (44% vs 23%), due to hematologic toxicities. CONCLUSIONS: There was no difference in efficacy (evaluated by progression-free survival) between elderly and younger patients. Although grade 3/4 hematologic toxicities were frequently observed in the elderly patients, they were easily managed with dose adjustment. PMID- 30293945 TI - First-in-man Safety and Efficacy of the ClearRing Implant for the Treatment of Benign Prostatic Hyperplasia. AB - BACKGROUND: Although effective for benign prostatic hyperplasia (BPH), transurethral resection of the prostate (TURP) can be associated with side effects including prolonged recovery, storage and voiding symptoms, and a risk of acute urinary retention. OBJECTIVE: To test a new minimally invasive device for the treatment of lower urinary tract symptoms (LUTS) due to BPH, involving implantation of a C-shaped nitinol ring (ClearRing) in a circular incision in the prostatic tissue using an electrocuting blade over a dilatation balloon. DESIGN, SETTING, AND PARTICIPANTS: This was a multicenter single-arm clinical trial involving 29 men with severe symptomatic BPH. INTERVENTION: Implantation of a ClearRing device under regional anesthesia. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Effectiveness in alleviating LUTS was assessed in terms of International Prostate Symptom Score (IPSS) at baseline and 3, 6, and 12 mo after the procedure. To evaluate changes from baseline, a general estimating equation model was fitted to IPSS, the Quality of Life (QOL) scale, Benign Prostatic Hyperplasia Impact Index, maximum flow rate (Qmax), and postvoid residual volume. Statistical significance was defined as p<0.05. RESULTS AND LIMITATIONS: The average age was 71.4 yr, prostate size was 35-50cm3, and IPSS was 21.6. All procedures were successfully completed with one implant in 28 patients and two implants in one patient. No serious complications occurred. Patients experienced symptom relief by 3 mo that was sustained to 12 mo. Mean IPSS, QOL, and Qmax improved by 45%, 41%, and 40% by 3 mo, and 53%, 52%, and 49% by 12 mo, respectively (p<0.05). Adverse events were mild and transient. There were no reports of loss of antegrade ejaculation or any effects on erectile function. Implantation positioning failed in 11/29 patients, who then underwent uneventful TURP. After modification of the delivery device, the success rate for implant positioning improved from 5/13 patients to 13/16 patients. Study limitations include the single-arm nature and the low patient number. CONCLUSIONS: We demonstrated preliminary feasibility of the ClearRing device for minimally invasive treatment of BPH in men. Further studies are needed to confirm the safety and efficacy of this approach. PATIENT SUMMARY: In this study we tested outcomes after implantation of a ClearRing device in patients with benign prostatic hyperplasia. We found that the device was safe and effective. However, there was a high rate of implantation failure due to malpositioning, which was significantly improved following modification of the delivery device. PMID- 30293946 TI - Current Use of Three-dimensional Model Technology in Urology: A Road Map for Personalised Surgical Planning. AB - CONTEXT: Despite the current era of "precision surgery", an unmet need for an optimal surgical planning and navigation still remains for most genitourinary malignancies. In this setting, the 3D virtual reconstruction of 2D cross sectional imaging has been increasingly adopted to facilitate the surgeon in better understanding the surgical anatomy. OBJECTIVE: To provide a short overview of the most recent evidences on the current applications of 3D virtual and printed reconstructions in urologic surgery. EVIDENCE ACQUISITION: A non systematic review of the literature was performed. Medline, PubMed, the Cochrane Database and Embase were screened for studies regarding the use of 3D models in urology. EVIDENCE SYNTHESIS: 3D reconstruction technology has been primarily implemented with the purpose of surgical planning and navigation, especially in the management of prostate and kidney cancer. Augmented reality is still in a rudimental phase, especially in the field of prostate cancer. The (poor) Literature already published suggests that the 3D virtual and printed models could be helpful for the comprehension and learning of the surgical strategy by the young urologists and, at the meantime, could enhance the quality of the dialog with the patients, giving them a direct perception of the disease and its treatment. CONCLUSION: Notwithstanding the current limitations and the sporadic experiences available in the Literature, 3D models technology is perceived as a useful tool for the surgical planning, especially in the field of kidney and prostate cancer, physician education/training and patient counselling. PATIENT SUMMARY: In the field of prostate and kidney cancer, the optimal surgical planning and the patient counselling seems to be improved by the use of 3D reconstruction technology based on the preoperative imaging. PMID- 30293947 TI - [Obstetrical anal sphincter injuries and vacuum-assisted delivery at term in primiparas]. AB - OBJECTIVES: Operative Vaginal Delivery (OVD) is subject to a risk of perineal tears especially of Obstetrical Anal Sphincter Injuries (OASIS) that are associated with more complications and impaired quality of life. The main objective of this study was to compare the rate of OASIS in primipara at term with fetus in cephalic presentation depending on the type of delivery: OVD using vacuum extractor and spontaneous delivery. METHODS: This is a single-center retrospective study between 01/01/2010 and 12/31/2014 including all primipara who delivered vaginally at term, a single and living fetus in cephalic presentation. Perineal lesions were classified according to the WHO classification. The primary endpoint was the proportion of OASIS. RESULTS: 3552 patients were included: 2496 spontaneous deliveries (SD) and 1056 OVD (29.72 %). There were twenty sphincter tears (0.56 %): 7 in SD group (0.28 %) and 13 in OVD (1.23 %), P<0.0001, OR=5.10 [2.00; 12.99]. Other risk factors associated with OASIS in univariable analysis were: maternal age (>=30 years), duration of expulsive efforts (>=20min) and a birth weight>=4000g. CONCLUSION: In these patients, the risk of OASIS in case of AI increases by a factor of 5;10. The high rate of AI in these patients exposes them to a real risk of OASIS. However, the proportion of OASIS in this group remains lower than those reported in the literature and is barely higher than the national overall rate, despite a very restrictive policy of the use of episiotomy.

AB - INTRODUCTION: Uterine rupture in the healthy uterus is a rare obstetrical complication, not much suspected and with badly identified risk factors. Thus, there exists frequent delay for treatment and therefore fetal-maternal important morbidity and mortality. This article describes clinical signs and symptoms, management, and maternal and neonatal prognosis of uterine rupture. METHODS: Descriptive retrospective study within 13 maternity hospitals, reporting 10 series of cases of uterine rupture on gravid healthy uterus during the third trimester of pregnancy. RESULT: The incidence was 2.8/100,000 births. Surgical treatment was conservative in 9 out of 10 cases, the maternal prognosis was good with no maternal deaths and 6 out of 7 patients had at least one subsequent pregnancy. The fetal prognosis was more reserved, with 2 fetal or neonatal deaths and 1 with motor disability. 6/6 patients (100%) had at least one iterative Caesarean section during the following pregnancies with healthy fetuses. CONCLUSION: In this series of 10 cases over 25years, maternal-fetal morbidity and mortality were significant, in agreement with the literature. Maternal prognosis remained favorable. When surgical treatment is conservative a subsequent pregnancy is possible and an iterative cesarean section must be performed. PMID- 30293950 TI - The promising role of miR-296 in human cancer. AB - MicroRNAs (MiRNAs) are small non-protein-coding RNA molecules that silence mRNA translation; they have emerged as key players in nearly all biological processes in the past few decades. In particular, miRNAs are involved in carcinogenic processes, with either oncogenic or tumor suppressive roles in human cancers. The abnormal expression of miR-296 has important roles in various cellular processes inhuman malignancies, including cell proliferation, apoptosis, invasion, and epithelial-mesenchymal transition. Epigenetic mechanisms and upstream transcription factors are responsible for the regulation of miR-296 expression in cancer. In this review, we summarize and discuss the most recent findings regarding miR-296 in cancer, including its downstream targets, functional effects, underlying regulatory mechanisms, and therapeutic potentials. PMID- 30293951 TI - Strong androgen receptor expression is not useful in distinguishing GATA3 + metastases. AB - GATA binding protein 3 (GATA3) immunohistochemical expression is commonly considered to be a sensitive and specific diagnostic marker for breast and urothelial carcinomas in surgical pathology practice. However, since its expression has been also demonstrated in other tumors, GATA3 should be better used in conjunction with other immunohistochemical markers to establish tumor primitivity in metastatic setting. Interestingly, GATA3 expression seems to be significantly correlated with androgen receptor (AR) expression in breast carcinoma. In addition, strong AR expression -defined as immunohistochemical positivity in more than 60% of tumor cells- was suggested to be 100% specific for breast origin in GATA3+ metastases. The aim of this study was to verify whether strong AR expression may actually be useful to determine primivity in GATA3+ metastatic setting. Thus, we investigated AR and GATA3 immuno-expression in a cohort of metastatic tumors derived from urothelial, breast, endometrial and salivary gland carcinomas. We did not find any GATA3 or AR expression in the metastases from endometrial or salivary gland carcinomas, while GATA3 expression was seen in the majority of metastases from urothelial or breast carcinomas. In addition, strong AR expression was seen in 73% and in 47% of metastatic breast and urothelial carcinomas, respectively. On the whole, our findings confirm that GATA3 is sensitive and specific for breast and urothelial origin in metastatic setting. According to our results, strong AR expression is not useful to distinguish breast from urothelial primitivity, as previously suggested. PMID- 30293952 TI - Clear cell dysplasia in a sessile serrated adenoma. PMID- 30293953 TI - FITC-labeled d-glucose analog is suitable as a probe for detecting insulin dependent glucose uptake. AB - The detection of the insulin-dependent glucose uptake is a vital part in the research of diabetes. To establish a sensitive assay for measuring glucose uptake in living cells, we synthesized a FITC linked d-glucosamine 2 as a probe. 2 was obtained by the reaction of commercially available d-glucosamine hydrochloride and FITC and was determined as a single anomeric form by 1H NMR and 13C NMR. 2 exhibited good water solubility and stability. An uptake assay in HepG2 cells with or without insulin demonstrated that FITC showed strong cellular uptake, whereas uptake of 2 is much less but is insulin dependent. This suggests that 2 is specifically transported into cells through a receptor that is regulated by insulin and has potential application in screening of compounds or genes that regulate the insulin-dependence in cell-based assays. PMID- 30293955 TI - Examination procedures and interventions for the hip in the management of low back pain: a survey of physical therapists. AB - OBJECTIVES: The main research aims were to investigate whether physical therapists are examining the hip(s) in individuals with a primary complaint of low back pain (LBP) and if so, the interventions being provided that target the hip(s). METHODS: An anonymous electronic survey was distributed to the membership of the American Physical Therapy Association Orthopaedic and Sports Sections, as well as that of the American Academy of Orthopaedic Manual Physical Therapists. Participant demographics and survey responses were analyzed using descriptive statistics. Associations between variables were examined using chi-square analysis. RESULTS: The estimated response rate was 18.4% (n=1163, mean age 40.5+/ 11.4 years). The majority of respondents (91%, n=1059) reported they always or most of the time examined the hip(s) in individuals with LBP. The most common examination items utilized were hip strength testing (94%, n=948), passive range of motion (91%, n=921) and muscle flexibility testing (90%, n=906). The most common interventions included hip strengthening (94%, n=866) and hip flexibility exercises (90%, n=814). Respondents enrolled in or having completed a post professional fellowship were more likely to utilize hip joint manual therapy techniques (x2=25.3, p=<0.001) and less likely to prescribe hip flexibility exercises (x2=7.9, p=0.005) or use electrophysical modalities (x2=4.3, p=0.039). CONCLUSIONS: Physical therapists commonly examine and provide interventions directed at the hip(s) for individuals with LBP. Post-professional fellowship training appears to influence the intervention selection of the physical therapist, with an increase in usage of hip joint manual therapy and a decrease in hip muscle flexibility and modality usage. PMID- 30293954 TI - Can high-intensity interval training change cardiac autonomic control? A systematic review. AB - BACKGROUND: High intensity interval training (HIIT) has been used as a cardiovascular exercise strategy to promote greater adherence in cardiovascular rehabilitation. However, little is known about the effect of this training modality on cardiac autonomic control. OBJECTIVE: To perform a systematic review to evaluate the effects of HIIT on cardiac autonomic responses in humans. METHODS: PEDro, SCOPUS and PubMed were searched from the inception to March 29th, 2018. Moreover, the methodological quality and statistical reporting from all eligible clinical trials were assessed by the PEDro scale. The articles were eligible if: The primary objective was related to the effects of HIIT on the cardiac autonomic nervous system. Outcomes evaluated were indirect measures of cardiac autonomic control, represented by HRV indexes. RESULTS: The search strategies resulted in 339 citations and 2 additional citations were identified through other sources. After deleting the duplicate articles and revising the full text, 6 articles were included. Overall, the results showed an improvement in parasympathetic and/or sympathetic modulation after HIIT, when evaluated by linear and non-linear indexes of HRV. CONCLUSIONS: HIIT is a promising tool to improve the cardiac autonomic control, with more recommendation in healthy individuals and patients with metabolic syndrome. PMID- 30293956 TI - Associations between type and severity of hip pathology with pre-operative patient reported outcome measures. AB - BACKGROUND: The relationship between hip pathology and patient reported outcome responses following hip surgery has been previously investigated. No studies have investigated the relationship between pathology and patient reported outcome responses prior to surgery. OBJECTIVES: (1) Determine the prevalence of chondral and labral pathology identified during hip arthroscopy. (2) Determine the association between intra-articular findings and patient reported outcome scores in a pre-arthroscopy hip pain population. METHODS: Sixty-seven (22 female) participants scheduled for hip arthroscopy after clinical examination and radiographic assessment completed a series of patient reported outcomes (Hip Disability and Osteoarthritis Outcome Score; International Hip Outcome Tool; Pain on Activity; Visual Analogue Scale). Pathology discovered/addressed during arthroscopy was classified. Univariable and multivariable linear regression models were used to assess the relationship between demographics, pathology and patient reported outcome responses. RESULTS: Ninety-one percent of participants had labral pathology; 76% had acetabular chondropathy and 31% had femoral head chondropathy. Across the ten patient reported outcome subscales, severe femoral head chondropathy and large labral tears had the greatest number of significant associations with patient reported outcome scores. The strongest association was with 'Hip Disability and Osteoarthritis Outcome Score symptoms and stiffness' subscale, where severe femoral head chondropathy explained 22% of variability in symptoms and stiffness, when adjusted for Body Mass Index and presence of pincer morphology (p=0.002). CONCLUSION: Severe femoral head chondropathy and large labral tears along with a high prevalence of labral pathology and acetabular chondropathy were relatively common findings during hip arthroscopy. Severe femoral head chondropathy and large labral tears are most associated with patient reported outcome's, however, at best only explain 22% of the variability. PMID- 30293957 TI - Paediatric auditory brainstem implantation: The South Asian experience. AB - INTRODUCTION: Paediatric Auditory Brainstem Implantation (ABI) is indicated for children with congenital cochlear aplasia, absent/hypoplastic vestibulocochlear nerve, for whom cochlear implantation is not possible. Knowledge of the anatomical landmarks and variants in anatomy of the brainstem is vital for ABI surgery. METHOD: Study was done at Auditory implant centre in Madras ENT research foundation, which includes 24 children who had undergone ABI surgery and are being followed up for 1 year, post operatively. Aims were to study the anatomical variants and the outcomes of ABI implantation. To determine if different anatomical variants effect placement of ABI electrode. To assess the patient outcomes by Categories of auditory Performance (CAP) scores and Speech Intelligibility Ratings (SIR) scores. RESULTS: All the candidates showed gradual improvement in audiological and verbal outcomes after the ABI. The mean CAP and SIR scores after 6 months of AVHT were 2.07 and 1.37 respectively. After 1 year of auditory verbal rehabilitation therapy CAP was 3.42 and SIR was 2.33. Flocculus of the cerebellum can be of different grades. Though, there was difficulty in insertion of the electrode in subjects with anatomical variants, the outcomes were comparable with other subjects. CONCLUSION: ABI surgery involves frequent anatomical variations surrounding the lateral recess which makes the positioning of the auditory prosthesis difficult. Variants during the surgery can make the placement of ABI electrodes difficult, but promising results were seen all the implantees. PMID- 30293958 TI - Strategy for facial nerve management during surgical removal of benign jugular foramen tumors: Outcomes and indications. AB - OBJECTIVE: Classical surgical management of jugular foramen (JF) tumors usually requires facial nerve rerouting which results in permanent facial palsy in most patients. The purpose of the article is to study the outcomes of different rerouting techniques, and to discuss their indications. MATERIAL AND METHODS: We retrospectively reviewed 98 patients with JF tumors operated at our center between January 2008 and December 2016 using different surgical approaches with the following procedures for facial nerve management: total anterior rerouting (TR), partial anterior rerouting (PR), and fallopian bridge (FB) technique. The data for facial nerve management, surgical outcome and postoperative facial nerve function were collected from the medical records. RESULTS: In the study, there were 48 males and 50 females. Of them, 61 (62.2%) were jugular paragangliomas, 22 (22.4%) schwannomas, and 15 (15.3%) meningiomas. Total tumor removal was achieved in 95 (96.9%) patients, while near-total removal was achieved in 3 (3.1%) paragangliomas. TR was applied in 31 (31.6%) patients with PR in 26 (26.5%) patients, and FB in 41 (41.8%) patients. The mean follow-up duration was 39.4+/ 22.6 months, and 2 recurrences of paragangliomas were observed. Seventy-five patients (76.5%) had good facial function (HB I-II) at 1 year after surgery, the patients who received a TR approach presented significantly less HB I-II FN function (48.4%) than those with PR (82.6%, P<0.05) or those with FB technique (95.1%, P<0.001). 21 patients (21.4%) presented new-onset lower cranial nerve dysfunction of which 13 recovered at 1 year after surgery. CONCLUSION: Facial nerve management in JF tumors should be tailored individually. No-rerouting methods, such as the fallopian bridge technique, bring significantly better results in terms of facial nerve function, which might be performed first during surgery; its indication is based mainly on the tumor type and extent. PMID- 30293959 TI - Resolvin E3 attenuates lipopolysaccharide-induced depression-like behavior in mice. AB - Eicosapentaenoic acid (EPA)-derived resolvin E1 (RvE1) and E2 (RvE2) have antidepressant effects. Here, we investigated the antidepressant effects of resolvin E3 (RvE3) in a mouse model of lipopolysaccharide (LPS)-induced depression. We observed that LPS (0.8 mg/kg, i.p.) significantly increased immobility time on the tail suspension test, and this depression-like behavior was dose-dependently attenuated by intracerebroventricular infusion of RvE3 (10 or 100 ng). No effects of LPS or intracerebroventricular infusion of RvE3 on locomotor activity were observed. These results indicate that RvE3, as well as RvE1 and RvE2, have antidepressant effects. PMID- 30293960 TI - Anti-tumor activity of Escherichia coli Shiga toxin A subunit delivered by SF9 insect cells. AB - Cancer remains a major health problem around the world. A Shiga toxin is a bacterial toxin often produced by Shigella dysenteriae and Escherichia coli. A subunit of the Shiga toxin (StxA) is a cytotoxic agent which could be used to induce death in cancer cells. StxA expressed from baculovirus was evaluated in a pTriExTM expression vector. The baculovirus vector was used for the A subunit delivery of StxA. StxA cell cytotoxicity was induced by the virus and assessed in the MCF7 and HeLa cell lines. In addition, the breast cancer cytotoxicity of the expressed StxA was also assessed in a cancer induced in mice. The cytotoxicity of the recombinant StxA baculovirus with different multiplicities of infection (MOI) was measured. The results showed that significant cytotoxicity can be induced on the mammalian epithelial breast cancer cell lines, MCF7 and HeLa cells with MOI >= 2. The results also showed that a malignant tumor induced by MCF7 could be inhibited in a mouse cancer model. Therefore, it can be concluded that StxA, expressed by baculovirus, could be used for in vitro and in vivo gene delivery. In this study StxA, delivered by the baculovirus inhibited cell proliferation, and eliminated HeLa and MCF7 cells, in vitro. In conclusion, this method can be used as a safe alternative for anticancer drug delivery inside cancer cells. PMID- 30293961 TI - Relationship between the fluorescence intensity of rhodamine-labeled orexin A and the calcium responses in cortical neurons: An in vivo two-photon calcium imaging study. AB - Neural responses to a ligand vary widely between neurons; however, the mechanisms underlying this variation remain unclear. One possible mechanism is a variation in the number of receptors expressed in each neural membrane. Here, we synthesized a rhodamine-labeled orexin A compound, enabling us to quantify the amount of orexin binding to its receptors, OX1 and OX2, which principally couple to the Gq/11 protein. The rhodamine intensity and calcium response were measured under tetrodotoxin application from insular cortical glutamatergic neurons in Thy1-GCaMP6s transgenic mice using an in vivo two-photon microscope. Applying rhodamine-labeled orexin A (10 MUM) to the cortical surface gradually and heterogeneously increased both the intensity of the rhodamine fluorescence and [Ca2+]i. Calcium responses started simultaneously with the increase in rhodamine labeled orexin fluorescence and reached a plateau within several minutes. We classified neurons as high- and low-responding neurons based on the peak amplitude of the [Ca2+]i increase. The rhodamine fluorescence intensity was larger in the high-responding neurons than the low-responding neurons. Preapplication of SB334867 and TCS-OX2-29, OX1 and OX2 antagonists, respectively, decreased the proportion of high-responding neurons. These results suggest that the diverse receptor expression level in neural membranes is involved in mechanisms underlying varied neural responses, including [Ca2+]i increases. PMID- 30293962 TI - Outcomes of shoulder abduction after nerve surgery in patients over 50 years following traumatic brachial plexus injury. AB - PURPOSE: There is controversy regarding the effectiveness of brachial plexus reconstruction in older patients, as outcomes are thought to be poor. The aim of this study is to determine the outcomes of shoulder abduction obtained after nerve reconstruction in patients over the age of 50 years and factors related to success. METHODS: Forty patients over the age of 50 years underwent nerve surgery to improve shoulder function after a traumatic brachial plexus injury. Patients were evaluated pre- and postoperatively for shoulder abduction strength and range of motion (ROM); Disability of the Arm, Shoulder and Hand (DASH) scores; pain; age bracket; gender; body mass index (BMI); delay from injury to operation; concomitant trauma; severity of trauma; and type of reconstruction. RESULTS: The average age was 58.2 years (range 50-77 years) with an average follow-up of 18.8 months. The average modified British Medical Research Council (BMRC) shoulder abduction grade improved significantly from 0.23 to 2.03 (p < 0.005). Fourteen patients achieved functional shoulder abduction of >= M3 postoperatively. There was no correlation between age or age range stratification and BMRC grade or those obtaining useful shoulder abduction >= M3. Active shoulder abduction improved significantly from 18.25 degrees to 40.64 degrees , with no difference on the basis of age or age stratification. There were improved modified BMRC grades with nerve transfers versus nerve grafts. Less patients achieved >= M3 function if surgery was delayed > 6 months. The mean DASH score decreased from 45.3 to 40.7 postoperatively, and the average pain score decreased from 3.7 to 3.0. Patients with a higher postoperative BMRC grade for shoulder abduction had improved postoperative DASH scores and VAS for pain (p = 0.011 and 0.005, respectively). CONCLUSION: Brachial plexus nerve reconstruction for shoulder abduction in patients over the age of 50 years can yield useful BMRC scores and ROM, and age should not be used to exclude nerve reconstruction in these patients.

AB - BACKGROUND: Breast cancer-related lymphedema (BCRL) is a feared late complication. Treatment options are lacking at present. Recent studies have suggested that mesenchymal stromal cells can alleviate lymphedema. Herein, we report the results from the first human pilot study with adipose-derived regenerative cells (ADRCs) for treating BCRL with 1 year of follow-up. MATERIAL AND METHODS: We included 10 patients with BCRL. ADRCs were injected directly into the axillary region together with a scar-releasing fat grafting procedure. Primary endpoint was change in arm volume. Secondary endpoints were change in patient-reported outcomes, changes in lymph flow, and safety. RESULTS: During follow-up, no significant change in volume was noted. Patient-reported outcomes improved significantly with time. Five patients reduced their use of conservative management. Quantitative lymphoscintigraphy did not improve on the lymphedema affected arms. ADRCs were well tolerated, and only minor transient adverse events related to liposuction were noted. CONCLUSIONS: In this pilot study, a single injection of ADRCs improved lymphedema based on patient-reported outcome measures, and there were no serious adverse events during the follow-up period. Lymphoscintigraphic evaluation showed no improvement after ADRC treatment. There was no change in excess arm volume. Results of this trial need to be confirmed in randomized clinical trials.

AB - The CorA Mg2+ channel is a homopentamer with five-fold symmetry. Each monomer consists of a large cytoplasmic domain and two transmembrane helices connected via a short periplasmic loop. In the Thermotoga maritima CorA crystal structure, a Mg2+ is bound between D89 of one monomer and D253 of the adjacent monomer (M1 binding site). Release of Mg2+ from these sites has been hypothesized to cause opening of the channel. We generated mutants to disrupt Mg2+ interaction with the M1 site. Crystal structures of the D89K/D253K and D89R/D253R mutants, determined to 3.05 and 3.3 A, respectively, showed no significant structural differences with the wild type structure despite absence of Mg2+ at the M1 sites. Both mutants still appear to be in the closed state. All three mutant CorA proteins exhibited transport of 63Ni2+, indicating functionality. Thus, absence of Mg2+ from the M1 sites neither causes channel opening nor prevents function. We also provide evidence that the T. maritima CorA is a Mg2+ channel and not a Co2+ channel. PMID- 30293966 TI - The oligomeric plasticity of Hsp20 of Sulfolobus acidocaldarius protects environment-induced protein aggregation and membrane destabilization. AB - Small heat shock proteins (sHsps) are a ubiquitous family of molecular chaperones that rescue misfolded proteins from irreversible aggregation during cellular stress. Many such sHsps exist as large polydisperse species in solution, and a rapid dynamic subunit exchange between oligomeric and dissociated forms modulates their function under a variety of stress conditions. Here, we investigated the structural and functional properties of Hsp20 from thermoacidophilic crenarchaeon Sulfolobus acidocaldarius. To provide a framework for investigating the structure function relationship of Hsp20 and understanding its dynamic nature, we employed several biophysical and biochemical techniques. Our data suggested the existence of a ~24-mer of Hsp20 at room temperature (25 degrees C) and a higher oligomeric form at higher temperature (50 degrees C-70 degrees C) and lower pH (3.0-5.0). To our surprise, we identified a dimeric form of protein as the functional conformation in the presence of aggregating substrate proteins. The hydrophobic microenvironment mainly regulates the oligomeric plasticity of Hsp20, and it plays a key role in the protection of stress-induced protein aggregation. In Sulfolobus sp., Hsp20, despite being a non-secreted protein, has been reported to be present in secretory vesicles and it is still unclear whether it stabilizes substrate proteins or membrane lipids within the secreted vesicles. To address such an issue, we tested the ability of Hsp20 to interact with membrane lipids along with its ability to modulate membrane fluidity. Our data revealed that Hsp20 interacts with membrane lipids via a hydrophobic interaction and it lowers the propensity of in vitro phase transition of bacterial and archaeal lipids. PMID- 30293965 TI - The importance of the membrane interface as the reference state for membrane protein stability. AB - The insertion of nascent polypeptide chains into lipid bilayer membranes and the stability of membrane proteins crucially depend on the equilibrium partitioning of polypeptides. For this, the transfer of full sequences of amino-acid residues into the bilayer, rather than individual amino acids, must be understood. Earlier studies have revealed that the most likely reference state for partitioning very hydrophobic sequences is the membrane interface. We have used MUs-scale simulations to calculate the interface-to-transmembrane partitioning free energies DeltaGS->TM for two hydrophobic carrier sequences in order to estimate the insertion free energy for all 20 amino acid residues when bonded to the center of a partitioning hydrophobic peptide. Our results show that prior single residue scales likely overestimate the partitioning free energies of polypeptides. The correlation of DeltaGS->TM with experimental full-peptide translocon insertion data is high, suggesting an important role for the membrane interface in translocon-based insertion. The choice of carrier sequence greatly modulates the contribution of each single-residue mutation to the overall partitioning free energy. Our results demonstrate the importance of quantifying the observed full-peptide partitioning equilibrium, which is between membrane interface and transmembrane inserted, rather than combining individual water-to membrane amino acid transfer free energies. PMID- 30293967 TI - Pharmacological inhibition of autophagy by 3-MA attenuates hyperuricemic nephropathy. AB - Autophagy has been identified as a cellular process of bulk degradation of cytoplasmic components and its persistent activation is critically involved in the renal damage induced by ureteral obstruction. However, the role and underlying mechanisms of autophagy in hyperuricemic nephropathy (HN) remain unknown. In the present study, we observed that inhibition of autophagy by 3 methyladenine (3-MA) abolished uric acid-induced differentiation of renal fibroblasts to myofibroblasts and activation of transforming growth factor-beta1 (TGF-beta1), epidermal growth factor receptor (EGFR), and Wnt signaling pathways in cultured renal interstitial fibroblasts. Treatment with 3-MA also abrogated the development of HN in vivo as evidenced by improving renal function, preserving renal tissue architecture, reducing the number of autophagic vacuoles, and decreasing microalbuminuria. Moreover, 3-MA was effective in attenuating renal deposition of extracellular matrix (ECM) proteins and expression of alpha smooth muscle actin (alpha-SMA) and reducing renal epithelial cells arrested at the G2/M phase of cell cycle. Injury to the kidney resulted in increased expression of TGF-beta1 and TGFbeta receptor I, phosphorylation of Smad3 and TGF beta-activated kinase 1 (TAK1), and activation of multiple cell signaling pathways associated with renal fibrogenesis, including Wnt, Notch, EGFR, and nuclear factor-kappaB (NF-kappaB). 3-MA treatment remarkably inhibited all these responses. In addition, 3-MA effectively suppressed infiltration of macrophages and lymphocytes as well as release of multiple profibrogenic cytokines/chemokines in the injured kidney. Collectively, these findings indicate that hyperuricemia induced autophagy is critically involved in the activation of renal fibroblasts and development of renal fibrosis and suggest that inhibition of autophagy may represent a potential therapeutic strategy for HN. PMID- 30293968 TI - Spatial distribution of endogenous tissue protease activity in gastric carcinoma mapped by MALDI mass spectrometry imaging. AB - Aberrant protease activity has been implicated in the etiology of various prevalent diseases including neurodegeneration and cancer, in particular metastasis. Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) has recently been established as a key technology for bioanalysis of multiple biomolecular classes such as proteins, lipids, and glycans. However, it has not yet been systematically explored for investigation of a tissue's endogenous protease activity. In this study, we demonstrate that different tissues, spray-coated with substance P as a tracer, digest this peptide with different time-course profiles. Furthermore, we reveal that distinct cleavage products originating from substance P are generated transiently and that proteolysis can be attenuated by protease inhibitors in a concentration-dependent manner. To show the translational potential of the method, we analyzed protease activity of gastric carcinoma in mice. Our MSI and quantitative proteomics results reveal differential distribution of protease activity - with strongest activity being observed in mouse tumor tissue, suggesting the general applicability of the workflow in animal pharmacology and clinical studies. PMID- 30293971 TI - Open-Label Placebo: Reflections on a Research Agenda. AB - Open-label placebos (OLP)-placebo pills honestly prescribed-have challenged the notion that placebos require either deception or concealment to evoke salubrious benefits. This essay describes how the author arrived at the counter-intuitive OLP hypothesis, discusses evidence for OLP effectiveness, and examines mechanistic explanations for OLP. Current dominant theories such as expectation and conditioning are found to be insufficient or inaccurate. The author proposes that emerging concepts of prediction and error processing (PEP), Bayesian brain, and embodied cognition are more appropriate models for understanding OLP. As a neural processing model, PEP argues that sensory predictions are embedded in and inseparable from perceptions; PEP circumvents mind-body dualism. The author discusses how OLP, mostly non-consciously, might perturb aberrant symptom amplifications and central sensitization resulting in perceptions of improvement in symptoms. Placebo effects are neurologically encoded predictions, less what patients think and more what they enact and perform. PMID- 30293969 TI - Effects of mipomersen, an apolipoprotein B100 antisense, on lipoprotein (a) metabolism in healthy subjects. AB - Elevated lipoprotein (a) [Lp(a)] levels increase the risk for CVD. Novel treatments that decrease LDL cholesterol (LDL-C) have also shown promise for reducing Lp(a) levels. Mipomersen, an antisense oligonucleotide that inhibits apoB synthesis, is approved for the treatment of homozygous familial hypercholesterolemia. It decreases plasma levels of LDL-C by 25% to 39% and lowers levels of Lp(a) by 21% to 39%. We examined the mechanisms for Lp(a) lowering during mipomersen treatment. We enrolled 14 healthy volunteers who received weekly placebo injections for 3 weeks followed by weekly injections of mipomersen for 7 weeks. Stable isotope kinetic studies were performed using deuterated leucine at the end of the placebo and mipomersen treatment periods. The fractional catabolic rate (FCR) of Lp(a) was determined from the enrichment of a leucine-containing peptide specific to apo(a) by LC/MS. The production rate (PR) of Lp(a) was calculated from the product of Lp(a) FCR and Lp(a) concentration (converted to pool size). In a diverse population, mipomersen reduced plasma Lp(a) levels by 21%. In the overall study group, mipomersen treatment resulted in a 27% increase in the FCR of Lp(a) with no significant change in PR. However, there was heterogeneity in the response to mipomersen therapy, and changes in both FCRs and PRs affected the degree of change in Lp(a) concentrations. Mipomersen treatment decreases Lp(a) plasma levels mainly by increasing the FCR of Lp(a), although changes in Lp(a) PR were significant predictors of reductions in Lp(a) levels in some subjects. PMID- 30293970 TI - Pharmacotherapy of pain in cancer patients - recommendations of the Polish Association for the Study of Pain, Polish Society of Palliative Medicine, Polish Society of Oncology, Polish Society of Family Medicine, Polish Society of Anaesthesiology and Intensive Therapy and Association of Polish Surgeons. AB - Guidelines for the pharmacotherapy of pain in cancer patients were developed by a group of 21 experts of the Polish Association for the Study of Pain, Polish Society of Palliative Medicine, Polish Society of Oncology, Polish Society of Family Medicine, Polish Society of Anaesthesiology and Intensive Therapy and Association of Polish Surgeons. During a series of meetings, the experts carried out an overview of the available literature on the treatment of pain in cancer patients, paying particular attention to systematic reviews and more recent randomized studies not included in the reviews. The search was performed in the EMBASE, MEDLINE, and Cochrane Central Register of Controlled Trials databases using such keywords as "pain", "cancer", "pharmacotherapy", "analgesics", and similar. The overviewed articles included studies of pathomechanisms of pain in cancer patients, methods for the assessment of pain in cancer patients, and drugs used in the pharmacotherapy of pain in cancer patients, including non-opioid analgesics (paracetamol, metamizole, non-steroidal anti-inflammatory drugs), opioids (strong and weak), coanalgesics (glucocorticosteroids, alpha2-adrenergic receptor agonists, NMDA receptor antagonists, antidepressants, anticonvulsants, topical medications) as well as drugs used to reduce the adverse effects of the analgesic treatment and symptoms other than pain in patients subjected to opioid treatment. The principles of opioid rotation and the management of patients with opioidophobia were discussed and recommendations for the management of opioid induced hyperalgesia were presented. Drugs used in different types of pain experienced by cancer patients, including neuropathic pain, visceral pain, bone pain, and breakthrough pain, were included in the overview. Most common interactions of drugs used in the pharmacotherapy of pain in cancer patients as well as the principles for the management of crisis situations. In the final part of the recommendations, the issues of pain and care in dying patients are discussed. Recommendations are addressed to physicians of different specialties involved in the diagnostics and treatment of cancer in their daily practice. It is the hope of the experts who took part in the development of these recommendations that the recommendations would become helpful in everyday medical practice and thus contribute to the improvement in the quality of care and the efficacy of pain treatment in this group of patients. PMID- 30293972 TI - Reining in the Placebo Effect. AB - What is known as the "placebo effect" has received increasing attention in recent years in scientific investigation and the news media. The concept of the placebo effect, however, is subject to confusion and misleading implications, especially when applied broadly. This essay argues that it is desirable to confine the concept, as applied to biomedicine, to the therapeutic effects of deliberate placebo interventions. The author examines in detail the conceptual problems in characterizing the therapeutic benefits that flow from communication in the clinician-patient relationship as placebo effects. PMID- 30293973 TI - Editors' Introduction to Special Section on Meaning Response and the Placebo Effect. PMID- 30293974 TI - Meaning and an Overview of the Placebo Effect. AB - The placebo effect can be defined as a bodily change due to the symbolic effects of a treatment or treatment situation. It is further explained by the meaning model: a positive placebo response is most likely to occur when the meaning of the illness is altered for the patient in a positive direction. Moerman's suggestion that "placebo effect" be replaced by "meaning response" is based in part on dissatisfaction with the characterization of placebo, which is avoided when one focuses instead more comprehensively on placebo effect. The placebo effect can then be explained by the mental processes of expectancy or conditioning and their effect on specific neuro-chemical processes that bring about end-organ changes. PMID- 30293975 TI - The Meaning Response, "Placebo," and Methods. AB - In 2002, Dan Moerman outlined three candidate explanations for the "placebo response": the "conditioned stimulus-response," Irving Kirsch's "response expectancy" explanation, and the "meaning response." The meaning response, Moerman argued, was the only one of the three candidate explanations that could cover all the data, gained from decades of RCTs and centuries of historical record. Moerman went so far as to propose replacing the term "placebo effect/response" with the term "meaning response," because people are not responding to placebos, since there is nothing to respond to; people are responding to meanings. There is evidence of medically significant meaning responses where there is no evidence for conditioning. Similarly, there is evidence for such responses where those subject to them lack the knowledge epistemic capital-required to form the beliefs which might constitute an expectation. Something else, neither conditioning nor propositional attitudes, explained placebo responses, and Moerman proposed the meaning response. While the authors consider the meaning response to avoid the pitfalls of conditioning and response-expectancy, it has been subject to criticism. The criticisms have focused on what is seen as the explanation falling foul of the naturalistic demand and not fitting with prevalent predilections in the philosophy of mind and cognitive science. This article seeks to allay these worries and proposes the inclusion of ethnomethodological fieldwork in future research. PMID- 30293976 TI - A Critical (and Cautiously Optimistic) Appraisal of Moerman's "Meaning Response". AB - In this article we propose a critical reassessment of Daniel Moerman's "meaning response." First, we reconstruct and criticize Moerman's original proposal of introducing the "meaning response" as a way of clarifying some terminological and conceptual issues in the placebo debate. Next we evaluate the criticisms that Moerman's proposal is epistemically moot since other existing and more empirically grounded models already account for all the phenomena that fall under the concept of the "meaning response." We conclude that Moerman's original proposal is inherently problematic and that, in order to be instrumentally useful in the future, the meaning response must be reconceived so that it may finally support, rather than oppose, other theoretical and empirical lines of research currently ongoing in the field of placebo studies. PMID- 30293978 TI - What Are the Benefits of a New Placebo Language? AB - This article examines three common strategies for dealing with the problems generated by the terms placebo and "placebo effect." These strategies are to redefine, to reconceptualize, and to eliminate our placebo language. The promise of these strategies is that a new language for talking about placebo phenomena may deliver clinical, ethical, and methodological advances. However, the nature and impact of these advances is rarely explored in detail. This article surveys some of the promised benefits of new terms such as "meaning response" and "contextual healing." The benefits are broadly similar across these strategies, but while they allow for clearer descriptions of phenomena and wider appreciation of the contextual aspects of medical practice, the open challenge for these strategies is not just to promise, but to show, the practical significance of their approaches to understanding placebo phenomena. PMID- 30293979 TI - Consensus in Placebo Studies: Lessons from The Philosophy of Science. AB - In the relatively nascent field of placebo studies, empirical studies have burgeoned. Yet debate about how to define the terms placebo and "placebo effect" has not abated. A number of prominent scholars (drawn from medical practice, as well as philosophy, psychology, and anthropology) continue to propose and defend different conceptual models for these terms, and the perception that conceptual debate persists is often given as one justification for new definitions. Paradoxically-in spite of this lively debate-this article finds considerable underlying agreement about definitional matters within placebo studies. Drawing on key insights from philosophy of science, and by exploring the nature of scientific consensus and normal scientific research, this paper argues that well developed placebo concepts form the basis for a placebo paradigm and that conceptual disagreement is overstated. PMID- 30293977 TI - The Placebo Phenomenon: A Narrow Focus on Psychological Models. AB - The placebo effect is a complex phenomenon that can be described from neurobiological, psychosocial, and epistemological perspectives. Different leaders in the field have proposed multiple theories and models that attempt to describe both the nature and the mechanisms of action underlying placebo effects. This article focuses on the most relevant psychological models that have been suggested for characterizing the different mechanisms underlying the placebo effect. We outline how the dynamic psychoneurobiological aspects of the placebo phenomenon can be a potential reliable and useful tool in daily clinical practice for illness and symptom management within a wide variety of specialties and health-care practices. PMID- 30293980 TI - 200 Years After Frankenstein. AB - Mary Shelley's Frankenstein is 200 years old and remains relevant to 21st-century scientific experimentation. Molecular biologists today have become especially bold in their attempts to cure diseases while remaining mindful of the real dangers of their research. Scientists presumably share an abiding concern about producing uncontrollable mutations in people, animals, and the wider environment, yet a sense of urgency appears to inform the current scientific willingness to take risks, especially in the realm of embryology and germ-line modification. This willingness to go more boldly than before could be influenced by the unprecedented ability of such gene-cutting technologies as CRISPR to make immediate and lasting improvements to persons suffering from certain diseases and other physical malignancies, but also by an acculturated sense that such persons deserve to participate more fully in broader society. PMID- 30293981 TI - Who's Winning the IRB Wars? The Struggle for the Soul of Human Research. AB - The origins and aspirations of institutional review boards (IRBs), the American oversight system for research with human subjects, are well known, and their failures have been documented and disputed for decades. Contention about IRBs is often ideological and unsatisfying, but their shortcomings are real. A new wave of attention to the promise and problems of this oversight system has coincided with the years-long effort to update the federal "Common Rule." Three very different recent books-Rebecca Dresser's Silent Partners, Robert Klitzman's Ethics Police, and Carl Schneider's The Censor's Hand-draw from a wealth of experiential, empirical, and rhetorical resources to triangulate this long standing set of concerns and tensions at individual, institutional, and system levels. Schneider's volume exemplifies anti-government critiques of the regulation of science; Klitzman's catalogues IRB members' reflections on the ambiguities inherent in their regulatory role; and, by far the most interestingly, Dresser examines the potential contributions of experienced research subjects to the oversight process. Taken together, these books can help refocus the IRB wars on the ever-challenging relationships among goals, uncertainties, and practicalities, and move us toward understanding and addressing those relationships in their current (and rapidly changing) scientific and societal context. Some real progress might even result. PMID- 30293982 TI - Job Satisfaction Among Doctors from Jiangsu Province in China. AB - BACKGROUND Doctors' job satisfaction has an important effect on medical and health services. This study assessed the level of job satisfaction in Chinese doctors and explored how influencing factors differ between general practitioners and specialists. MATERIAL AND METHODS The Minnesota Satisfaction Questionnaire (MSQ) on job satisfaction was distributed to 1883 doctors in Jiangsu province, including 850 general practitioners and 1033 specialists. Data analysis was performed with SPSS 20.0. A one-way ANOVA was used to analyze doctors' job satisfaction and logistic regression analysis was used for multivariate analysis. Correlation analysis was done on the 5 dimensions of satisfaction. RESULTS The average MSQ score of all surveyed doctors was 3.11+/-0.87, with general practitioners (GPs) and specialists scores of 2.81+/-0.84 and 3.35+/-0.82, respectively. Analysis of doctor satisfaction indicated that gender, age, marital status, educational attainment, professional title, and seniority were statistically significant (P<0.05). Overall satisfaction was most closely related to the job itself (r=0.96); work, work environment, and interpersonal relationship were closely related with lead management. CONCLUSIONS The level of job satisfaction of Chinese doctors, especially general practitioners, needs to be improved. Measures such as improving education levels, work environment, and relationships should to be taken soon to improve doctors' job satisfaction in China. PMID- 30293983 TI - Eosinophilic Granulomatosis with Polyangiitis (EGPA) with an Unusual Manifestation of Mid-Ventricular Obstruction Caused by Endocardial Thrombus. AB - BACKGROUND Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic vasculitis of unknown cause accompanied by prominent eosinophilia. Intracardiac thrombosis is one of the major cardiac complications in EGPA that may cause thromboembolism. CASE REPORT A 46-year-old male presenting with intermittent chest pain and numbness of the lower extremities was admitted to our center. His case was complicated by multiple brain infarcts and endocardial thrombosis in the left ventricle. A condition of restrictive cardiomyopathy was also found. After a thorough workup, he was diagnosed with antineutrophil cytoplasmic antibody (ANCA) positive EGPA. Interestingly, the thrombus was accompanied by a pressure gradient producing mid-ventricular obstruction. The patient improved reasonably with immunosuppression and anticoagulation treatment, in addition to heart failure treatment, and had a concomitant regression of the thrombus and reduction of the pressure gradient. CONCLUSIONS For an EGPA patient complicated by intraventricular obstruction caused by endocardial thrombosis, which could accelerate the release of the thrombus into the systemic circulation resulting in a life-threating condition, timely and aggressive measures against cardioembolic complications should be considered. PMID- 30293984 TI - Long-range PCR libraries and next-generation sequencing for pharmacogenetic studies of patients treated with anti-TNF drugs. AB - Biological therapy with anti-tumor necrosis factor-alpha (anti-TNF-alpha) monoclonal antibodies significantly increased the effectiveness of autoimmune disease treatment compared with conventional medicines. However, anti-TNF-alpha drugs are relatively expensive and a response to the therapy is reported in only 60-70% of patients. Moreover, in up to 5% of patients adverse drug reactions occur. The various effects of biological treatment may be a potential consequence of interindividual genetic variability. Only a few studies have been conducted in this field and which refer to single gene loci. Our aim was to design and optimize a methodology for a broader application of pharmacogenetic studies in patients undergoing anti-TNF-alpha treatment. Based on the current knowledge, we selected 16 candidate genes: TNFRSF1A, TNFRSF1B, ADAM17, CASP9, FCGR3A, LTA, TNF, FAS, IL1B, IL17A, IL6, MMP1, MMP3, S100A8, S100A9, and S100A12, which are potentially involved in the response to anti-TNF-alpha therapy. As a research model, three DNA samples from Crohn's disease (CD) patients were used. Targeted genomic regions were amplified in 23 long-range (LR) PCR reactions and after enzymatic fragmentation amplicon libraries were prepared and analyzed by next generation sequencing (NGS). Our results indicated 592 sequence variations located in all fragments with coverage range of 5-1089. We demonstrate a highly sensitive, flexible, rapid, and economical approach to the pharmacogenetic investigation of anti-TNF-alpha therapy using amplicon libraries and NGS technology. PMID- 30293985 TI - The IICR and the non-stationary structured coalescent: towards demographic inference with arbitrary changes in population structure. AB - In the last years, a wide range of methods allowing to reconstruct past population size changes from genome-wide data have been developed. At the same time, there has been an increasing recognition that population structure can generate genetic data similar to those produced under models of population size change. Recently, Mazet et al. (Heredity 116:362-371, 2016) showed that, for any model of population structure, it is always possible to find a panmictic model with a particular function of population size changes, having exactly the same distribution of T2 (the coalescence time for a sample of size two) as that of the structured model. They called this function IICR (Inverse Instantaneous Coalescence Rate) and showed that it does not necessarily correspond to population size changes under non-panmictic models. Besides, most of the methods used to analyse data under models of population structure tend to arbitrarily fix that structure and to minimise or neglect population size changes. Here, we extend the seminal work of Herbots (PhD thesis, University of London, 1994) on the structured coalescent and propose a new framework, the Non-Stationary Structured Coalescent (NSSC) that incorporates demographic events (changes in gene flow and/or deme sizes) to models of nearly any complexity. We show how to compute the IICR under a wide family of stationary and non-stationary models. As an example we address the question of human and Neanderthal evolution and discuss how the NSSC framework allows to interpret genomic data under this new perspective. PMID- 30293986 TI - Copy-number variants in clinical genome sequencing: deployment and interpretation for rare and undiagnosed disease. AB - PURPOSE: Current diagnostic testing for genetic disorders involves serial use of specialized assays spanning multiple technologies. In principle, genome sequencing (GS) can detect all genomic pathogenic variant types on a single platform. Here we evaluate copy-number variant (CNV) calling as part of a clinically accredited GS test. METHODS: We performed analytical validation of CNV calling on 17 reference samples, compared the sensitivity of GS-based variants with those from a clinical microarray, and set a bound on precision using orthogonal technologies. We developed a protocol for family-based analysis of GS based CNV calls, and deployed this across a clinical cohort of 79 rare and undiagnosed cases. RESULTS: We found that CNV calls from GS are at least as sensitive as those from microarrays, while only creating a modest increase in the number of variants interpreted (~10 CNVs per case). We identified clinically significant CNVs in 15% of the first 79 cases analyzed, all of which were confirmed by an orthogonal approach. The pipeline also enabled discovery of a uniparental disomy (UPD) and a 50% mosaic trisomy 14. Directed analysis of select CNVs enabled breakpoint level resolution of genomic rearrangements and phasing of de novo CNVs. CONCLUSION: Robust identification of CNVs by GS is possible within a clinical testing environment. PMID- 30293987 TI - Identification of clinically actionable variants from genome sequencing of families with congenital heart disease. AB - PURPOSE: Congenital heart disease (CHD) affects up to 1% of live births. However, a genetic diagnosis is not made in most cases. The purpose of this study was to assess the outcomes of genome sequencing (GS) of a heterogeneous cohort of CHD patients. METHODS: Ninety-seven families with probands born with CHD requiring surgical correction were recruited for genome sequencing. At minimum, a proband parents trio was sequenced per family. GS data were analyzed via a two-tiered method: application of a high-confidence gene screen (hcCHD), and comprehensive analysis. Identified variants were assessed for pathogenicity using the American College of Medical Genetics and Genomics-Association for Molecular Pathology (ACMG-AMP) guidelines. RESULTS: Clinically relevant genetic variants in known and emerging CHD genes were identified. The hcCHD screen identified a clinically actionable variant in 22% of families. Subsequent comprehensive analysis identified a clinically actionable variant in an additional 9% of families in genes with recent disease associations. Overall, this two-tiered approach provided a clinically relevant variant for 31% of families. CONCLUSIONS: Interrogating GS data using our two-tiered method allowed identification of variants with high clinical utility in a third of our heterogeneous cohort. However, association of emerging genes with CHD etiology, and development of novel technologies for variant assessment and interpretation, will increase diagnostic yield during future reassessment of our GS data. PMID- 30293989 TI - Long-term follow-up in PMM2-CDG: are we ready to start treatment trials? AB - PURPOSE: PMM2-CDG is the most common congenital disorder of glycosylation (CDG), which presents with either a neurologic or multisystem phenotype. Little is known about the longitudinal evolution. METHODS: We performed data analysis on PMM2-CDG patients' clinical features according to the Nijmegen CDG severity score and laboratory data. Seventy-five patients (28 males) were followed up from 11.0 +/- 6.91 years for an average of 7.4 +/- 4.5 years. RESULTS: On a group level, there was no significant evolution in overall clinical severity. There was some improvement in mobility and communication, liver and endocrine function, and strabismus and eye movements. Educational achievement and thyroid function worsened in some patients. Overall, the current clinical function, the system specific involvement, and the current clinical assessment remained unchanged. On follow-up there was improvement of biochemical variables with (near) normalization of activated partial thromboplastin time (aPTT), factor XI, protein C, antithrombin, thyroid stimulating hormone, and liver transaminases. CONCLUSION: PMM2-CDG patients show a spontaneous biochemical improvement and stable clinical course based on the Nijmegen CDG severity score. This information is crucial for the definition of endpoints in clinical trials. PMID- 30293988 TI - De novo missense variants in RAC3 cause a novel neurodevelopmental syndrome. AB - PURPOSE: RAC3 is an underexamined member of the Rho GTPase gene family that is expressed in the developing brain and linked to key cellular functions. De novo missense variants in the homolog RAC1 were recently associated with developmental disorders. In the RAC subfamily, transforming missense changes at certain shared residues have been observed in human cancers and previously characterized in experimental studies. The purpose of this study was to determine whether constitutional dysregulation of RAC3 is associated with human disease. METHODS: We discovered a RAC3 variant in the index case using genome sequencing, and searched for additional variants using international data-sharing initiatives. Functional effects of the variants were assessed using a multifaceted approach generalizable to most clinical laboratory settings. RESULTS: We rapidly identified five individuals with de novo monoallelic missense variants in RAC3, including one recurrent change. Every participant had severe intellectual disability and brain malformations. In silico protein modeling, and prior in vivo and in situ experiments, supported a transforming effect for each of the three different RAC3 variants. All variants were observed in databases of somatic variation in cancer. CONCLUSIONS: Missense variants in RAC3 cause a novel brain disorder, likely through a mechanism of constitutive protein activation. PMID- 30293990 TI - Molecular autopsy by trio exome sequencing (ES) and postmortem examination in fetuses and neonates with prenatally identified structural anomalies. AB - PURPOSE: To determine the diagnostic yield of combined exome sequencing (ES) and autopsy in fetuses/neonates with prenatally identified structural anomalies resulting in termination of pregnancy, intrauterine, neonatal, or early infant death. METHODS: ES was undertaken in 27 proband/parent trios following full autopsy. Candidate pathogenic variants were classified by a multidisciplinary clinical review panel using American College of Medical Genetics and Genomics (ACMG) guidelines. RESULTS: A genetic diagnosis was established in ten cases (37%). Pathogenic/likely pathogenic variants were identified in nine different genes including four de novo autosomal dominant, three homozygous autosomal recessive, two compound heterozygous autosomal recessive, and one X-linked. KMT2D variants (associated with Kabuki syndrome postnatally) occurred in two cases. Pathogenic variants were identified in 5/13 (38%) cases with multisystem anomalies, in 2/4 (50%) cases with fetal akinesia deformation sequence, and in 1/4 (25%) cases each with cardiac and brain anomalies and hydrops fetalis. No pathogenic variants were detected in fetuses with genitourinary (1), skeletal (1), or abdominal (1) abnormalities. CONCLUSION: This cohort demonstrates the clinical utility of molecular autopsy with ES to identify an underlying genetic cause in structurally abnormal fetuses/neonates. These molecular findings provided parents with an explanation of the developmental abnormality, delineated the recurrence risks, and assisted the management of subsequent pregnancies. PMID- 30293991 TI - Pitfalls of clinical exome and gene panel testing: alternative transcripts. AB - PURPOSE: Clinical exome and gene panel testing can provide molecular diagnoses for patients with rare Mendelian disorders, but for many patients these tests are nonexplanatory. We investigated whether interrogation of alternative transcripts in known disease genes could provide answers for additional patients. METHODS: We integrated alternative transcripts for known neonatal epilepsy genes with RNA-Seq data to identify brain-expressed coding regions that are not evaluated by popular neonatal epilepsy clinical gene panel and exome tests. RESULTS: We found brain expressed alternative coding regions in 89 (30%) of 292 neonatal epilepsy genes. The 147 regions encompass 15,713 bases that are noncoding in the primary transcripts analyzed by the clinical tests. Alternative coding regions from at least 5 genes carry reported pathogenic variants. Three candidate variants in these regions were identified in public exome data from 337 epilepsy patients. Incorporating alternative transcripts into the analysis of neonatal epilepsy genes in 44 patient genomes identified the pathogenic variant for the epilepsy case and 2 variants of uncertain significance (VUS) among the 43 control cases. CONCLUSION: Assessment of alternative transcripts in exon-based clinical genetic tests, including gene panel, exome, and genome sequencing, may provide diagnoses for patients for whom standard testing is unrevealing, without introducing many VUS. PMID- 30293992 TI - Variant data sharing by clinical laboratories through public databases: consent, privacy and further contact for research policies. AB - Access to detailed variant data is key to inform and verify the interpretation of genomic data. Clinical laboratories can play a significant role in sharing patients' data through public variant databases. To facilitate data sharing, various public databases, such as ClinVar and DECIPHER have been established, which accept data submission from laboratories, clinicians, researchers, and patients. Despite clear benefits to sharing, questions may arise about the adequate form of consent to be obtained from patients when sharing data from their clinical tests through public databases. In this paper, we provide an overview and critical analysis of the relevant consent policies of the major public databases, and of the consent forms of clinical laboratories that share variant data via ClinVar.

AB - INTRODUCTION: Celiac disease (CeD) is an autoimmune enteropathy which affects approximately 0.7% of the global population. While first-degree relatives (FDR) of patients with CeD have a 7.5% risk of developing enteropathy, many remain protected. Therefore, intestinal mucosa of FDR might have protective compensatory mechanisms against immunological injury. We have explored the protective mechanisms that may be active in intestinal mucosa of FDR. METHODS: Intestinal mucosal biopsies (4-5 pieces) from treatment naive patients with CeD (n = 12), FDR (n = 12) (anti-tTG negative) and controls (n = 12) (anti-tTG negative) were obtained from each individual and subjected to microarray analysis using HT-12-v4 Human Expression BeadChips (Illumina). Differential gene expression analysis was carried out among CeD, FDR and controls; and resulting gene lists were analyzed using gene ontology and pathway enrichment tools. RESULTS: Patients with CeD, FDR and control groups displayed significant differential gene expression. Thirty seven genes were upregulated and 372 were downregulated in the intestinal mucosa of FDR in comparison to CeD and controls. Pseudogenes constituted about 18% (315/1751) of FDR differentially expressed genes, and formed "clusters" that associated uniquely with individual study groups. The three study groups segregated into distinct clusters in unsupervised (PCA) and supervised (random forests) modelling approaches. Pathways analysis revealed an emphasis on crypt villous maintenance and immune regulation in the intestinal mucosa of FDR. CONCLUSIONS: Our analysis suggests that the intestinal mucosa of celiac FDR consist of a unique molecular phenotype that is distinct from CeD and controls. The transcriptomic landscape of FDR promotes maintenance of crypt-villous axis and modulation of immune mechanisms. These differences clearly demonstrate the existence of compensatory protective mechanisms in the FDR intestinal mucosa. PMID- 30293995 TI - Phase II trial of palbociclib in patients with metastatic urothelial cancer after failure of first-line chemotherapy. AB - BACKGROUND: The majority of urothelial cancers (UC) harbor alterations in retinoblastoma (Rb) pathway genes that can lead to loss of Rb tumour suppressor function. Palbociclib is an oral, selective inhibitor of CDK 4/6 that restores Rb function and promotes cell cycle arrest. METHODS: In this phase II trial, patients with metastatic platinum-refractory UC molecularly selected for p16 loss and intact Rb by tumour immunohistochemistry received palbociclib 125 mg p.o. daily for 21 days of a 28-day cycle. Primary endpoint was progression-free survival at 4 months (PFS4) using a Simon's two-stage design. Next-generation sequencing including Rb pathway alterations was conducted. RESULTS: Twelve patients were enrolled and two patients (17%) achieved PFS4 with insufficient activity to advance to stage 2. No responses were seen. Median PFS was 1.9 months (95% CI 1.8-3.7 months) and median overall survival was 6.3 months (95% CI 2.2 12.6 months). Fifty-eight percent of patients had grade >=3 hematologic toxicity. There were no CDKN2A alterations found and no correlation of Rb pathway alterations with clinical outcome. CONCLUSIONS: Palbociclib did not demonstrate meaningful activity in selected patients with platinum-refractory metastatic UC. Further development of palbociclib should only be considered with improved integral biomarker selection or in rational combination with other therapies. PMID- 30293994 TI - MicroRNA-transcription factor network analysis reveals miRNAs cooperatively suppress RORA in oral squamous cell carcinoma. AB - Oral squamous cell carcinoma (OSCC) represents over 90% of oral cancer incidence, while its mechanisms of tumorigenesis remain poorly characterized. In this study, we applied RNA-seq and microRNA-seq methodologies in four pairs of cancer and adjacent normal tissues to profile the contribution of miRNAs to tumorigenesis altered functional pathways by constructing a comprehensive miRNA-mediated mRNA regulatory network. There were 213 differentially expressed (DE) miRNAs and 2172 DE mRNAs with the involvement of negative miRNA-mRNA interactions identified by at least two pairs of cancerous tissues. GO analysis revealed that the upregulated microRNAs significantly contributed to a global down-regulation of a number of transcription factors (TFs) in OSCC. Among the negative regulatory networks between the selected miRNAs (133) and TFs (167), circadian rhythm genes (RORA, RORB, RORC, and CLOCK) simultaneously regulated by multiple microRNAs were of particular interest. For instance, RORA transcript was predicted to be targeted by 25 co-upregulated miRNAs, of which, miR-503-5p, miR-450b-5p, miR-27a 3p, miR-181a-5p and miR-183-5p were further validated to directly target RORA, resulting in a stronger effect on RORA suppression together. In addition, we showed that the mRNA and protein expression levels of RORalpha were significantly decreased in most OSCC samples, associated with advanced clinical stage and poor prognosis. RORalpha significantly suppressed the proliferation of OSCC cells in vitro and in vivo. Attenuated RORalpha decreased p53 protein expression and suppressed p53 phosphorylation activity. Altogether, our results strongly suggest the importance of the role of miRNAs in regulating the activity of circadian rhythm-related TFs network during OSCC tumorigenesis, and provide further clues to understand the clinical link between circadian rhythm and cancer therapy. PMID- 30293996 TI - A minority-group of renal cell cancer patients with high infiltration of CD20+B cells is associated with poor prognosis. AB - BACKGROUND: The role of B-lymphocytes in solid tumours is unclear. Tumour biology studies have implied both anti- and pro-tumoural effects and prognostic studies have mainly linked B-cells to increased survival. This study aimed to analyse the clinical relevance of B-lymphocytes in renal cell cancer (RCC), where information on the prognostic impact is lacking. METHODS: Following immunohistochemistry (IHC) stainings with a CD20 antibody, density of CD20+ B-cells was quantified in an RCC discovery- and validation cohort. Associations of B-cell infiltration, determined by CD20 expression or a B-cell gene-signature, and survival was also analysed in 14 publicly available gene expression datasets of cancer, including the kidney clear cell carcinoma (KIRC) dataset. RESULTS: IHC analyses of the discovery cohort identified a previously unrecognised subgroup of RCC patients with high infiltration of CD20+ B-cells. The B-cell-high subgroup displayed significantly shorter survival according to uni- and multi-variable analyses. The association between poor prognosis and high density of CD20+ B-cells was confirmed in the validation cohort. Analyses of the KIRC gene expression dataset using the B-cell signature confirmed findings from IHC analyses. Analyses of other gene expression datasets, representing 13 different tumour types, indicated that the poor survival-association of B-cells occurred selectively in RCC. CONCLUSION: This exploratory study identifies a previously unrecognised poor prognosis subset of RCC with high density of CD20-defined B-cells. PMID- 30293997 TI - Ovarian tumours of different histologic type and clinical stage induce similar changes in lipid metabolism. AB - BACKGROUND: Previous results obtained from serum samples of late-stage, high grade serous ovarian carcinoma patients showed large alterations in lipid metabolism. To validate and extend the results, we studied lipidomic changes in early-stage ovarian tumours. In addition to serous ovarian cancer, we investigated whether these changes occur in mucinous and endometrioid histological subtypes as well. METHODS: Altogether, 354 serum or plasma samples were collected from three centres, one from Germany and two from Finland. We performed lipidomic analysis of samples from patients with malignant (N = 138) or borderline (N = 25) ovarian tumours, and 191 controls with benign pathology. These results were compared to previously published data. RESULTS: We found 39 lipids that showed consistent alteration both in early- and late-stage ovarian cancer patients as well as in pre- and postmenopausal women. Most of these changes were already significant at an early stage and progressed with increasing stage. Furthermore, 23 lipids showed similar alterations in all investigated histological subtypes. CONCLUSIONS: Changes in lipid metabolism due to ovarian cancer occur in early-stage disease but intensify with increasing stage. These changes occur also in other histological subtypes besides high-grade serous carcinoma. Understanding lipid metabolism in ovarian cancer may lead to new therapeutic and diagnostic alternatives.

PMID- 30293998 TI - Glucose homeostasis dependency on acini-islet-acinar (AIA) axis communication: a new possible pathophysiological hypothesis regarding diabetes mellitus. AB - Studies have highlighted the existence of two intra-pancreatic axes of communication: one involved in the regulation of enzyme production by insulin-the insular-acinar axis; and another involved in the regulation of insulin release by pancreatic enzymes-the acini-insular axis. Previous studies by our laboratory show that pancreatic enzymes can affect blood glucose homeostasis and insulin secretion independently of their digestive functions, both from the gut lumen and probably from the blood. As a result we would like to introduce here the concept of acini-islet-acinar (AIA) axis communication (feedback), which could play an important role in the development of obesity and diabetes type 2. The AIA feedback links the endocrine and exocrine parts of the pancreas and emphasizes the essential role that the pancreas plays, as a single organ, in the regulation of glucose homeostasis by amylase most probably in gut epithelium and by insulin and glucagon in peripheral blood.

AB - Abstract: Meso- and macroporous spherical silica gels of pore sizes in the range of 60-1000 A and 40-75 um particle size were investigated as a stationary phase for the separation and purification of polysaccharides and poly(ethylene glycols) (PEGs) of various MWs using an aqueous mobile phase. Sephadex and Bio-Gel were used for comparison as the most common stationary phases for similar purposes. The separation of dextrans of a mean MW = 31 kDa from small molecules (NaCl) was possible with SiO2 with a pore size of 60-300 A, but the observed efficiencies of a column of the same size were lower comparing with Sephadex or Bio-Gel. In the case of oxidized alginic acid only SiO2 of the 60 A pore size was suitable, while Sephadex, Bio-Gel and other investigated silicas were not efficient. Sephadex and 300-1000 A SiO2 offered the possibility of dividing dextrans with MW within the range of 1 MDa-10 kDa into fractions of various MWs, while Bio-Gel and 60 A SiO2 were not suitable. The investigated silica gels strongly adsorbed PEGs of MW 2-20 kDa. The amount adsorbed decreased with the increase of pore size and they were not useful as a stationary phase for this class of polymers. An advantage of SiO2 of the investigated particle size was a very low back pressure comparing with Sephadex. A considerably lower price of silica offers time- and cost-efficient separation of polysaccharides. Graphical Abstract: PMID- 30294005 TI - Malaria and Early African Development: Evidence from the Sickle Cell Trait. AB - We examine the effect of malaria on economic development in Africa over the very long run. Using data on the prevalence of the mutation that causes sickle cell disease, we measure the impact of malaria on mortality in Africa prior to the period in which formal data were collected. Our estimate is that in the more afflicted regions, malaria lowered the probability of surviving to adulthood by about ten percentage points, which is twice the current burden of the disease. The reduction in malaria mortality has been roughly equal to the reduction in other causes of mortality. We then ask whether the estimated burden of malaria had an effect on economic development in the period before European contact. Using data at the ethnic group level, we find little evidence of a negative relationship between malaria burden and population density or other measures of development. PMID- 30294003 TI - Movies promote tobacco use amongst adolescents: The need for policies to prevent this phenomenon. AB - Tobacco use is the primary preventable cause of death and disability in the world. To combat the tobacco epidemic, most countries have signed and ratified the World Health Organzation's Framework Convention on Tobacco Control (WHO FCTC). Article 13 of this treaty requires implementation of a comprehensive ban on tobacco advertising, promotion and sponsorship. Implementation guidelines for Article 13 recognize that the depiction of tobacco use in commercially-produced films promotes tobacco use amongst young people. In this article we review the relationship between the tobacco industry and the movie industry over the past 100 years; the cross sectional and longitudinal studies that demonstrate a causal relationship between exposure to movie smoking depictions and youth smoking initiation; and the policy interventions recommended by the WHO to limit youth exposure to tobacco in movies. PMID- 30294006 TI - Improving Performance and Retention in Introductory Biology with a Utility-Value Intervention. AB - One way to encourage performance and persistence in STEM fields is to have students write about the utility value (UV) or personal relevance of course topics to their life. This intervention has been shown to increase engagement and performance in introductory courses. However, questions remain about the longevity of the effects and how best to implement the intervention in terms of dosage and timing. We tested a UV intervention in the first semester of a two semester introductory biology sequence. For each of three units across the semester, students (N = 577) were randomly assigned to receive either a UV writing assignment, in which they explained why course material was useful to them personally, or a control assignment, in which they summarized course material. This fully crossed design tested the effect of UV dosage level (0, 1, 2, or 3 UV assignments) as well as the effect of timing (e.g., UV first, control first). We found that students exposed to any dosage of UV earned higher grades in the course, were more likely to enroll in the second course of the biology sequence, and were less likely to abandon their STEM major than students who did not receive any UV assignments. In terms of timing, students with a history of poor performance benefitted from writing a UV essay in the beginning of the semester, whereas higher-performing students benefitted from a UV essay at the end of the semester. Recommendations for practice are discussed. PMID- 30294007 TI - Interactive effects of herbivory and substrate orientation on algal community dynamics on a coral reef. AB - Herbivory is a significant driver of algal community dynamics on coral reefs. However, abiotic factors such as the complexity and orientation of the benthos often mediate the impact of herbivores on benthic communities. We experimentally evaluated the independent and interactive effects of substrate orientation and herbivorous fishes on algal community dynamics on a coral reef in the Florida Keys, USA. We created horizontal and vertical substrates, mimicking the trend in the reduction of vertical surfaces of coral reefs, to assess how algal communities developed either with herbivory (open areas) or without herbivory (herbivore exclosures). We found that substrate orientation was the dominant influence on macroalgal community composition. Herbivores had little impact on community development of vertical substrates as crustose algae dominated these substrates regardless of being in exclosures or open areas. In contrast, herbivores strongly impacted communities on horizontal substrates, with upright macroalgae (e.g., Dictyota spp., articulated coralline algae) dominating herbivore exclosures, while filamentous turf algae and sediment dominated open areas. Outside of exclosures, differences between vertical and horizontal substrates exposed to herbivores persisted despite similar intensity of herbivory. Our results suggest that the orientation of the reef benthos has an important impact on benthic communities. On vertical surfaces, abiotic factors may be more important for structuring algal communities while herbivory may be more important for controlling algal dynamics in flatter areas. Thus, the decline in structural complexity of Caribbean coral reefs and the flattening of reef substrates may fundamentally alter the impact that herbivores have on benthic community dynamics. PMID- 30294008 TI - Bathyal and abyssal demersal bait-attending fauna of the Eastern Mediterranean Sea. AB - Baited cameras were deployed over a depth range of 532-5111 m in the Ionian Sea to characterise the large mobile fauna. The planned installation of a neutrino telescope also offers the potential for biological observatories. The current study was intended to aid observatory placement. At increasing depths, sediment was observed to become more uniform and animal burrows and tracks reduced. A total of 10 species of deep-sea fishes were identified from images; four elasmobranchs, which were not recorded deeper than 1841 m, and six teleosts. At depths > 3000 m, including Calypso Deep, the deepest point in the Mediterranean, only one fish species was observed; the Mediterranean grenadier, Coryphaenoides mediterraneus (3400-5111 m), extending this species' maximum recorded depth to 5111 m. Four species of decapod crustacea could be identified from images. The dressed deep-sea shrimp, Acanthephyra eximia (1346-5111 m) was the only invertebrate recorded at abyssal depths, including the deepest point. A faunal change was detected at ~ 1000 m depth. Incorporating other studies from the Eastern Mediterranean identified additional faunal boundaries at ~ 1500 m and ~ 2500 m. The time from landing the observation equipment to the arrival of the first fish increased exponentially with depth at a slower rate to that observed in the Atlantic Ocean. The estimated density of bait-attending deep-sea fish was, therefore, significantly impoverished compared to the Atlantic Ocean at equivalent depth. Barriers to colonisation, low resource input, and high temperature at depth relative to the Atlantic Ocean are probable causes of the impoverished fauna. PMID- 30294010 TI - MMPAC Information.

AB - Overview: Of sexual minority respondents, 29.5% said they concealed their sexual identify in medical school. Although most (67.5%) were "out" about their identity, the authors note that this is not all that much better than the estimate of 44% 2 decades ago. (Some respondents declined to answer this question).Sexual identity concealment was lowest among gay and lesbian (14.7%) and queer (22.2%) respondents. Most bisexuals (53.9%) and questioning (92.0%) respondents reported concealing their sexual identify in medical school. Purpose: To assess identity disclosure among sexual and gender minority (SGM) students pursuing undergraduate medical training in the United States and Canada. Method: From 2009 to 2010, a survey was made available to all medical students enrolled in the 176 MD-and DO-granting medical schools in the United States and Canada. Respondents were asked about their sexual and gender identity, whether they were "out" (i.e., had publicly disclosed their identity), and, if they were not, their reasons for concealing their identity. The authors used a mixed-methods approach and analyzed quantitative and qualitative survey data. Results: Of 5,812 completed responses (of 101,473 eligible respondents; response rate 5.7%), 920 (15.8%) students from 152 (of 176; 86.4%) institutions identified as SGMs. Of the 912 sexual minorities, 269 (29.5%) concealed their sexual identity in medical school. Factors associated with sexual identity concealment included sexual minority identity other than lesbian or gay, male gender, East Asian race, and medical school enrollment in the South or Central regions of North America. The most common reasons for concealing one's sexual identity were "nobody's business" (165/269; 61.3%), fear of discrimination in medical school (117/269; 43.5%), and social or cultural norms (110/269; 40.9%). Of the 35 gender minorities, 21 (60.0%) concealed their gender identity, citing fear of discrimination in medical school (9/21; 42.9%) and lack of support (9/21; 42.9%). Conclusions: SGM students continue to conceal their identity during undergraduate medical training. Medical institutions should adopt targeted policies and programs to better support these individuals. PMID- 30294036 TI - Former Missouri Medicine Editor Jordan W.

PMID- 30294049 TI - Scale of Small Particle Population in Activated Sludge Flocs. AB - The light scattering method is a valuable tool for accessing particle size and structure mainly due to fast and the nonintrusive nature of the measurement. The method is based on a scattered intensity pattern and depends on particle volume, particle morphology, the light wavelength and the scattering angle. The light scattering model, for particles characterised by a fractal structure, is enabled with the use of the Rayleigh-Gans-Debye theory under constrained assumptions. The range of validity of the Rayleigh-Gans-Debye is limited when primary particles constituting aggregate have a size close to the wavelength. In this work, a range of particle sizes was characterised in order to achieve a better understanding of the relationship between flocs size and its fractal dimension. Hence, the width of the power law regime is discussed. What is more, a specific fractal dimension value of activated sludge flocs was found for each of the analysed wastewater treatment plant, which suggests that the spatial structure of suspensions constituting the activated sludge is an individual characteristic of each treatment facility. It has been shown that activated sludge consists of microflocs from the range of 1-10 MUm, which constitute approximately 90% of all the population. PMID- 30294050 TI - ASSESSING ROBUSTNESS OF CLASSIFICATION USING ANGULAR BREAKDOWN POINT. AB - Robustness is a desirable property for many statistical techniques. As an important measure of robustness, breakdown point has been widely used for regression problems and many other settings. Despite the existing development, we observe that the standard breakdown point criterion is not directly applicable for many classification problems. In this paper, we propose a new breakdown point criterion, namely angular breakdown point, to better quantify the robustness of different classification methods. Using this new breakdown point criterion, we study the robustness of binary large margin classification techniques, although the idea is applicable to general classification methods. Both bounded and unbounded loss functions with linear and kernel learning are considered. These studies provide useful insights on the robustness of different classification methods. Numerical results further confirm our theoretical findings. PMID- 30294052 TI - Sentence interpretation by typically developing Vietnamese-English bilingual children. AB - We examined developing bilinguals' use of animacy and word order cues during sentence interpretation tasks administered in each of their languages. Participants were 6- to 8-year-old children who learned Vietnamese as a first language and English as a second language (n = 23). Participants listened to simple sentences and identified the agent or "doer" of the action. English-only peers (n = 23) served as a comparison group. Results indicated that the bilingual group relied more on animacy than the English-only group when interpreting sentences in English and that the bilingual group used a blending or "amalgamation" of cues to interpret English and Vietnamese sentences. Significant within-group variation in cue preference was investigated as a function of age and proficiency in the first language and second language. PMID- 30294053 TI - A longitudinal analysis of sentence interpretation in bilingual children. AB - This longitudinal study used sentence interpretation tasks to consider growth in language processing among school-aged children learning Vietnamese and English. Thirty-two children participated yearly over three time points. Children were asked to identify the agent of sentences that manipulated linguistic cues relevant to Vietnamese (animacy) and English (word order). Hierarchical linear modeling was used to examine change in cue use over time as well as the relation between cue use and proficiency in each language. Findings include exclusive reliance on word order by the end point, nearly identical group-level cue-use patterns across languages with individual variation, and positive relationships between language proficiency and cue use. Findings are discussed within the unified competition model (MacWhinney, 2004) and the literature on sequential bilingualism. PMID- 30294051 TI - Climate Migration at the Height and End of the Great Mexican Emigration Era. AB - Previous research has linked increasing climate-change-related variability to Mexico-US migration, but only under particular climatic/social conditions and periods of high irregular migration. Using the 2000 and 2010 Mexican censuses, we examine this environment-migration nexus across a broader set of socioecological contexts and during periods of both increasing (1995-1999) and declining (2005 2009) migration. Consistent with the notion that climate can "trap" populations in place, we find that frequent/severe bouts of hot or dry conditions are associated with lower US-bound migration from most of rural Mexico. However, we do find higher climate outmigration during episodes hot and dry climate, or out of places with lower vulnerability. Our comparisons across periods suggest that climate migration is affected by conditions in the U.S. in a similar or slightly weaker manner as other forms of migration are. Altogether, our findings suggest that rural Mexico is unlikely to push large numbers of international "climate refugees" and that climate migration is indeed sensitive to conditions in sending and destination areas. PMID- 30294054 TI - Modeling Heterogeneity in Healthcare Utilization Using Massive Medical Claims Data. AB - We introduce a modeling approach for characterizing heterogeneity in healthcare utilization using massive medical claims data. We first translate the medical claims observed for a large study population and across five years into individual-level discrete events of care called utilization sequences. We model the utilization sequences using an exponential proportional hazards mixture model to capture heterogeneous behaviors in patients' healthcare utilization. The objective is to cluster patients according to their longitudinal utilization behaviors and to determine the main drivers of variation in healthcare utilization while controlling for the demographic, geographic, and health characteristics of the patients. Due to the computational infeasibility of fitting a parametric proportional hazards model for high-dimensional, large sample size data we use an iterative one-step procedure to estimate the model parameters and impute the cluster membership. The approach is used to draw inferences on utilization behaviors of children in the Medicaid system with persistent asthma across six states.

AB - Standard corrections for missing data rely on the strong and generally untestable assumption of missing at random. Heckman-type selection models relax this assumption, but have been criticized because they typically require a selection variable which predicts non-response but not the outcome of interest, and can impose bivariate normality. In this paper we illustrate an application using a copula methodology which does not rely on bivariate normality. We implement this approach in data on HIV testing at a demographic surveillance site in rural South Africa which are affected by non-response. Randomized incentives are the ideal selection variable, particularly when implemented ex ante to deal with potential missing data. However, elements of survey design may also provide a credible method of correcting for non-response bias ex post. For example, although not explicitly randomized, allocation of food gift vouchers during our survey was plausibly exogenous and substantially raised participation, as did effective survey interviewers. Based on models with receipt of a voucher and interviewer identity as selection variables, our results imply that 37% of women in the population under study are HIV positive, compared to imputation-based estimates of 28%. For men, confidence intervals are too wide to reject the absence of non response bias. Consistent results obtained when comparing different selection variables and error structures strengthen these conclusions. Our application illustrates the feasibility of the selection model approach when combined with survey metadata.

AB - Radio-frequency electrosurgical procedures are widely used to simultaneously dissect and coagulate tissue. Experiments suggest that evaporation of cellular and intra-cellular water plays a significant role in the evolution of the temperature field at the tissue level, which is not adequately captured in a single scale energy balance equation. Here, we propose a two-scale model to study the effects of microscale phase change and heat dissipation in response to radiofrequency heating on the tissue level in electrosurgical ablation procedures. At the microscale, the conservation of mass along with thermodynamic and mechanical equilibrium is applied to obtain an equation-of-state (EOS) relating vapor mass fraction to temperature and pressure. The evaporation losses are incorporated in the macro-level energy conservation and results are validated with mean experimental temperature distributions measured from electrosurgical ablation testing on ex vivo porcine liver at different power settings of the electrosurgical instrument. Model prediction of water loss and its effect on the temperature along with the effect of the mechanical properties on results are evaluated and discussed. PMID- 30294057 TI - The Big Five, Everyday Contexts and Activities, and Affective Experience. AB - Prior research shows that personality traits predict time spent with different people and frequency of engagement in different activities. Further, personality traits, company, and activity are related to the experience of affect. However, little research has examined personality, context, and affect together in the same study. In the current study, 78 people described their Big Five traits and took part in a 1-week experience sampling study using mobile phones as a means for data collection. Participants indicated their current company, activity, and momentary affect along the dimensions of energetic arousal (EA), tense arousal (TA), and hedonic tone (HT). Poisson regressions revealed that traits predicted higher frequencies of trait-consistent contexts: for example, extraversion was related to more frequently being with various types of company. Results predicting contexts from multilevel logistic regressions were sparser. Multilevel models revealed that traits and contexts had main effects on affect, yet there were relatively few interactions of traits X contexts predicting affect. We discuss more specific implications of these findings. PMID- 30294058 TI - Investigation of Chiral Recognition by Molecular Micelles with Molecular Dynamics Simulations. AB - Molecular dynamics simulations were used to characterize the binding of the chiral drugs chlorthalidone and lorazepam to the molecular micelle poly-(sodium undecyl-(L)-leucine-valine). The project's goal was to characterize the nature of chiral recognition in capillary electrophoresis separations that use molecular micelles as the chiral selector. The shapes and charge distributions of the chiral molecules investigated, their orientations within the molecular micelle chiral binding pockets, and the formation of stereoselective intermolecular hydrogen bonds with the molecular micelle were all found to play key roles in determining where and how lorazepam and chlorthalidone enantiomers interacted with the molecular micelle. PMID- 30294059 TI - When equity matters for marital stability: Comparing German and U.S. couples. AB - Comparing West Germany and the United States, we analyze the association between equity - in terms of the relative gender division of paid and unpaid work hours - and the risk of marriage dissolution. Our aim is to identify under what conditions equity influences couple stability. We apply event-history analysis to marriage histories using data from the German Socio-Economic Panel for Western Germany and the Panel Study of Income Dynamics for the United States for the period 1986 to 2009. For the United States, we find that deviation from equity is particularly destabilizing when the wife under-benefits, and when both partners' paid work hours are similar. In West Germany, equity is less salient. Instead we find that the male breadwinner model remains the single most stable arrangement. PMID- 30294060 TI - Genomic Feature Selection by Coverage Design Optimization. AB - We introduce a novel data reduction technique whereby we select a subset of tiles to "cover" maximally events of interest in large-scale biological datasets (e.g., genetic mutations), while minimizing the number of tiles. A tile is a genomic unit capturing one or more biological events, such as a sequence of base pairs that can be sequenced and observed simultaneously. The goal is to reduce significantly the number of tiles considered to those with areas of dense events in a cohort, thus saving on cost and enhancing interpretability. However, the reduction should not come at the cost of too much information, allowing for sensible statistical analysis after its application. We envisage application of our methods to a variety of high throughput data types, particularly those produced by next generation sequencing (NGS) experiments. The procedure is cast as a convex optimization problem, which is presented, along with methods of its solution. The method is demonstrated on a large dataset of somatic mutations spanning 5000+ patients, each having one of 29 cancer types. Applied to these data, our method dramatically reduces the number of gene locations required for broad coverage of patients and their mutations, giving subject specialists a more easily interpretable snapshot of recurrent mutational profiles in these cancers. The locations identified coincide with previously identified cancer genes. Finally, despite considerable data reduction, we show that our covering designs preserve the cancer discrimination ability of multinomial logistic regression models trained on all of the locations (> 1M).

PMID- 30294061 TI - Nonlocal low-rank and sparse matrix decomposition for spectral CT reconstruction. AB - Spectral computed tomography (CT) has been a promising technique in research and clinic because of its ability to produce improved energy resolution images with narrow energy bins. However, the narrow energy bin image is often affected by serious quantum noise because of the limited number of photons used in the corresponding energy bin. To address this problem, we present an iterative reconstruction method for spectral CT using nonlocal low-rank and sparse matrix decomposition (NLSMD), which exploits the self-similarity of patches that are collected in multi-energy images. Specifically, each set of patches can be decomposed into a low-rank component and a sparse component, and the low-rank component represents the stationary background over different energy bins, while the sparse component represents the rest of different spectral features in individual energy bins. Subsequently, an effective alternating optimization algorithm was developed to minimize the associated objective function. To validate and evaluate the NLSMD method, qualitative and quantitative studies were conducted by using simulated and real spectral CT data. Experimental results show that the NLSMD method improves spectral CT images in terms of noise reduction, artifacts suppression and resolution preservation.

AB - Accurate segmentation of the left ventricle (LV) blood-pool and myocardium is required to compute cardiac function assessment parameters or generate personalized cardiac models for pre-operative planning of minimally invasive therapy. Cardiac Cine Magnetic Resonance Imaging (MRI) is the preferred modality for high resolution cardiac imaging thanks to its capability of imaging the heart throughout the cardiac cycle, while providing tissue contrast superior to other imaging modalities without ionizing radiation. However, there exists an inevitable misalignment between the slices in cine MRI due to the 2D + time acquisition, rendering 3D segmentation methods ineffective. A large part of published work on cardiac MR image segmentation focuses on 2D segmentation methods that yield good results in mid-slices, however with less accurate results for the apical and basal slices. Here, we propose an algorithm to correct for the slice misalignment using a Convolutional Neural Network (CNN)-based regression method, and then perform a 3D graph-cut based segmentation of the LV using atlas shape prior. Our algorithm is able to reduce the median slice misalignment error from 3.13 to 2.07 pixels, and obtain the blood-pool segmentation with an accuracy characterized by a 0.904 mean dice overlap and 0.56 mm mean surface distance with respect to the gold-standard blood-pool segmentation for 9 test cine MR datasets. PMID- 30294063 TI - Tumor margin assessment of surgical tissue specimen of cancer patients using label-free hyperspectral imaging. AB - We are developing label-free hyperspectral imaging (HSI) for tumor margin assessment. HSI data, hypercube (x,y,lambda), consists of a series of high resolution images of the same field of view that are acquired at different wavelengths. Every pixel on the HSI image has an optical spectrum. We developed preprocessing and classification methods for HSI data. We used spectral features from HSI data for the classification of cancer and benign tissue. We collected surgical tissue specimens from 16 human patients who underwent head and neck (H&N) cancer surgery. We acquired both HSI, autofluorescence images, and fluorescence images with 2-NBDG and proflavine from the specimens. Digitized histologic slides were examined by an H&N pathologist. The hyperspectral imaging and classification method was able to distinguish between cancer and normal tissue from oral cavity with an average accuracy of 90+/-8%, sensitivity of 89+/ 9%, and specificity of 91+/-6%. For tissue specimens from the thyroid, the method achieved an average accuracy of 94+/-6%, sensitivity of 94+/-6%, and specificity of 95+/-6%. Hyperspectral imaging outperformed autofluorescence imaging or fluorescence imaging with vital dye (2-NBDG or proflavine). This study suggests that label-free hyperspectral imaging has great potential for tumor margin assessment in surgical tissue specimens of H&N cancer patients. Further development of the hyperspectral imaging technology is warranted for its application in image-guided surgery. PMID- 30294065 TI - Family Structure and Child Food Insecurity: Evidence from the Current Population Survey. AB - Food insecurity-the lack of consistent access to adequate amounts of food-remains a reality for many American families. Although children are usually protected from reductions in food intake even in households with low food security, about 8 percent of all households with children also experienced reduced food intake and disrupted eating patterns. The research on child food insecurity and family structure is limited and the findings are mixed. Given the increasing complexity of families in the U.S., combined with sustained high levels of food insecurity during the last decade, a closer examination of this relationship is warranted. Using data from multiple years of the Current Population Survey Food Security Supplement (N=39,619 households) this study finds that children growing up in complex family households are more vulnerable to food insecurity, on average, than children growing up in two biological married-parent households. The results also show higher odds of child food insecurity among single mother households than among married biological or married stepfamilies suggesting a protective effect of marriage beyond economic resources. PMID- 30294066 TI - Irradiation effects in monazite-(Ce) and zircon: Raman and photoluminescence study of Au-irradiated FIB foils. AB - Lamellae of 1.5 um thickness, prepared from well-crystallised monazite-(Ce) and zircon samples using the focused-ion-beam technique, were subjected to triple irradiation with 1 MeV Au+ ions (15.6% of the respective total fluence), 4 MeV Au2+ ions (21.9%) and 10 MeV Au3+ ions (62.5%). Total irradiation fluences were varied in the range 4.5 * 1012 - 1.2 * 1014 ions/cm2. The highest fluence resulted in amorphisation of both minerals; all other irradiations (i.e. up to 4.5 * 1013 ions/cm2) resulted in moderate to severe damage. Lamellae were subjected to Raman and laser-induced photoluminescence analysis, in order to provide a means of quantifying irradiation effects using these two micro spectroscopy techniques. Based on extensive Monte Carlo calculations and subsequent defect-density estimates, irradiation-induced spectroscopic changes are compared with those of naturally self-irradiated samples. The finding that ion irradiation of monazite-(Ce) may cause severe damage or even amorphisation, is in apparent contrast to the general observation that naturally self-irradiated monazite-(Ce) does not become metamict (i.e. irradiation-amorphised), in spite of high self-irradiation doses. This is predominantly assigned to the continuous low temperature damage annealing undergone by this mineral; other possible causes are discussed. According to cautious estimates, monazite-(Ce) samples of Mesoproterozoic to Cretaceous ages have stored only about 1% of the total damage experienced. In contrast, damage in ion-irradiated and naturally self-irradiated zircon is on the same order; reasons for the observed slight differences are discussed. We may assess that in zircon, alpha decays create significantly less than 103 Frenkel-type defect pairs per event, which is much lower than previous estimates. Amorphisation occurs at defect densities of about 0.10 dpa (displacements per lattice atom). PMID- 30294067 TI - The influence of lithology on surface water sources. AB - Understanding the temporal and spatial variability of water sources within a basin is vital to our ability to interpret hydrologic controls on biogeochemical processes and to manage water resources. Water stable isotopes can be used as a tool to determine geographic and seasonal sources of water at the basin scale. Previous studies in the Coastal Range of Oregon reported that the variation in the isotopic signatures of surface water did not conform to the commonly observed "elevation effect", which exhibits a trend of increasing isotopic depletion with rising elevation. The primary purpose of this research is to investigate the mechanisms governing seasonal and spatial variations in the isotopic signature of surface waters within the Marys River Basin, located in the leeward side of the Oregon Coastal Range. Surface water and precipitation samples were collected every 2-3 weeks for isotopic analysis for one year. Our results confirmed the lack of elevational variation of surface water isotopes within this leeward basin. While we find elevational variation in precipitation in the eastern portion of the watershed, this elevation effect is counteracted by rainout with distance from the Pacific coast. In addition we found significant variation in surface water isotope values between catchments underlain predominantly by basalt or sandstone. The degree of separation was strongest during the summer when low flows reflect deeper groundwater sources. This indicates that baseflow within streams drained by each lithology is being supplied from two distinctly separate water sources. In addition, the flow of the Marys River is dominated by water originating from the sandstone water source, particularly during the low flow summer months. We interpreted that the difference in water source results from sandstone catchments having highly fractured geology or locally tipping to the east facilitating cross-basin water exchange from the windward to the leeward side of the Coast Range. Our results challenge topographic derived watershed boundaries in permeable sedimentary rocks; highlighting the overwhelming importance of underlying geology. PMID- 30294068 TI - The impact of culture conditions on growth and metabolomic profiles of freshwater cyanobacteria. AB - Cultured cyanobacteria produce secondary metabolites with a wide range of biological activities and are an important source of natural products. In the context of secondary metabolite discovery, microbial culture conditions are expected to support optimum growth, induce maximum chemical diversity, and be suitable for the majority of cyanobacterial strains. We investigated the effect of nitrate and phosphate on biomass production and metabolomic profiles of three filamentous freshwater cyanobacterial strains: cf. Oscillatoria sp. UIC 10045, Scytonema sp. UIC 10036, and Nostoc sp. UIC 10110. A standardized inoculation procedure allowed for the assessment of cell mass production. Dried cyanobacterial cell mass was extracted and analyzed by liquid chromatography coupled with high resolution mass spectrometry (UPLC-HRMS), followed by comparative metabolomics analysis using XCMS Online. Results showed that low nitrate media significantly reduced cell mass production for all three strains. Low nitrate also induced production of primary metabolites (heterocyst glycolipids) in strains UIC 10036 and UIC 10110. Changes in phosphate levels affected each strain differently. Strain UIC 10110 showed a significant increase in production of merocyclophane C when cultivated in low phosphate, while strain UIC 10036 displayed higher production of tolytoxin under high phosphate. Additionally, these experiments led to the identification of a potentially new peptide produced by strain UIC 10036. PMID- 30294069 TI - Color Doppler ultrasonography targeted reconstruction using pedicled perforator flaps-a systematic review and meta-analysis. AB - Background: Flaps are increasingly popularized in reconstructive surgery and there is need to test and increase their reliability. Color Doppler ultrasound has been stated to be valuable in flap planning. The aim of this study was to conduct a systematic review and meta-analysis of the literature of Color Doppler ultrasound targeted pedicled perforator flaps and provide information on outcomes and complication rates. Method: A systematic review and meta-analysis were conducted for articles published until April 2017 in PubMed and Embase. We aimed to include randomized clinical trials, meta-analysis, prospective studies, case control studies, and cohort studies written in English. We included studies where CDU was used to identify the perforator(s) prior to surgery. We evaluated the quality of the included studies using checklists recommended by the Cochrane group. Results: From the initial 219 studies, only 12 studies using Color Doppler targeted pedicled perforator flaps in 252 cases met the inclusion and exclusion criteria. Eleven of these were case series and one a prospective study. The incidence of major complications was 8% (21/252) and minor complications was 14%, comprising of mostly necrosis 8% (24/252) and venous congestion 8% (21/252). Conclusions: The reconstructive success rate following pedicled perforator flap reconstruction targeted by CDU appears to be high and the procedure provides a wide scope of applications and margin of safety. It is evident that the risk of venous congestion is 11 times greater in the lower extremities than the truncus, a finding that needs further attention in future studies.Level of Evidence: Level IV, risk/prognostic study. PMID- 30294070 TI - Poly Implant Prothese silicone breast implants: implant dynamics and capsular contracture. AB - Background: The Poly Implant Prothese (PIP) implants were withdrawn from the market in 2010 due to the use of low-grade silicone, causing a high risk for implant rupture. The aim of this study was to investigate the implant dynamics of PIP breast implants, as well as to determine the rate and predictors of implant gel bleeding, rupture, and capsular contracture in PIP implants. Methods: Eighty women with a total of 152 PIP implants who underwent a reoperation in 2012 were enrolled in this study. Physical investigation included assessing the Baker score and demographics were retrospectively traced in medical records. The pre- and post-operative volumes of the implants were calculated and their state was determined intraoperatively by the surgeon. Results: The implants were removed after a mean implant duration of 11 +/- 2.1 years. Gel bleed and implant rupture occurred in respectively 42 and 25% of the implants. Intact implants had post operative volume increase as well as decrease. There was a correlation between gel bleeding and more post-operative implant volume increase (P <= 0.05). Capsular contracture had a protective effect against post-operative implant volume increase (P <= 0.05), while a post-operative implant volume increase provided a protective influence in developing capsular contracture (P <= 0.05). Additionally, implant rupture led to a higher risk of capsular contracture (P <= 0.05). Conclusions: We managed to illustrate that PIP implant shells were too permeable and that there is a correlation between gel bleeding and the increase of the post-operative implant volume. Implant rupture led to a higher risk for developing capsular contracture.Level of evidence: Level III, risk / prognostic study. PMID- 30294071 TI - Applications and limitations of using patient-specific 3D printed molds in autologous breast reconstruction. AB - Background: Over the last years, several techniques have been proposed to improve the outcome of autologous breast reconstruction procedures. One of these innovations describes patient-specific, three-dimensional (3D) printed breast molds for intraoperative use based on 3D stereophotogrammetry. In this article, we want to share our preliminary experiences with producing such templates, its clinical possibilities and limitations in practice. Methods: Patient-specific templates were designed based on 3D stereophotogrammetry images. The 3D template was fabricated using a 3D printer. During breast reconstruction, the autologous flap was placed inside the printed template to aid the surgeon in determining the shape and volume of the autologous flap creating the desired breast dimensions. Patients were 3D-photographed 6 to 9 months post-operatively. Results: Three patients with unilateral breast reconstructions showed a width difference of 0.5 cm and mean volume difference of 211 ml between the reconstructed and contralateral breasts. In the three bilateral reconstructed patients, a mean difference in breast width and volume of respectively 0.5 cm and 16 ml was found. Conclusions: Patient-specific breast templates are inexpensive and relatively easy to design, while being practical and convenient to obtain insight in the dimensions of the desired breast during reconstruction, according to the operating surgeons. Patient selection is however critical, as patients must have sufficient donor volume and/or satisfying breast shape to be able to use the template to its full potential.Level of evidence: Level IV, therapeutic study.

AB - Lotus (Newnbo nucifera, Gaertn) is the most important aquatic vegetable in China, with a cultivation history of over 3000 years. The emergy, energy, material, and money flows of three lotus root cultivation modes in Wanqingsha, Nansha District, Guangzhou, China were examined using Energy Systems Language models and emergy evaluation to better understand their ecological and economic characteristics on multiple spatial and temporal scales. The natural resource foundations, economic characteristics and sustainability of these modes were evaluated and compared. The results showed that although all three modes were highly dependent on purchased emergy inputs, their potential impacts as measured by the local (ELRL) and global (ELRW) environmental loading ratios were less than 1.2 and 0.7, respectively. The lotus-fish mode was the most sustainable with its emergy index of sustainable development (EISD) 2.09 and 2.13 times that of the pure lotus and lotus-shrimp modes, respectively. All three lotus-root production modes had superior economic viability, since their Output/Input ratio ranged from 2.56 to 4.95. The results indicated that agricultural systems may have different environmental impacts and sustainability characteristics at different spatial and temporal scales, and that these impacts and characteristics can be simultaneously explored using integrated emergy and economic evaluations.

AB - Parents' supportive reactions to children's negative emotions are thought to promote children's social adjustment. Research heretofore has implicitly assumed that such reactions are equally supportive of children's adjustment across ages. Recent findings challenge this assumption, suggesting that during middle childhood, socialization practices previously understood as supportive may in fact impede children's social adjustment. We explored this possibility in a sample of 203 third-grade children and their mothers. Using structural equation modeling, we tested associations between mothers' supportive (i.e., problem- and emotion-focused) reactions to children's negative emotions and children's social skills and problems as reported by mothers and teachers. Mothers' supportive reactions predicted greater social adjustment in children as reported by mothers. Inverse associations, however, were found with teachers' reports of children's social adjustment: mothers' supportive reactions predicted fewer socioemotional skills and more problem behaviors. These contrasting patterns suggest potential unperceived costs associated with mothers' supportiveness of children's negative emotions for third-grade children's social adjustment in school and highlight the importance of considering associations between socialization practices and children's various social contexts. The findings also highlight a need for greater consideration of what supportiveness means across different developmental periods. PMID- 30294075 TI - Challenges to Healthcare in India - The Five A's. PMID- 30294076 TI - Capacity Building of Private Sector Workforce for Public Health Services in India: Scope and Challenges. AB - Indian health sector is a complex admixture of public and private providers, but several lacunae of public health service delivery system in terms of human resource, access, and quality have resulted in unprecedented growth of private sector. Although seamless delivery of services at rural and urban areas, timely approach, and improved information technology system are the strength of the private sector, this package comes at the cost of high out-of-pocket expenditure. Mobilization of private sector health workforce by their capacity building in terms of orientation toward public health services is one of the available solutions to move toward wider coverage of public health services. However, numerous challenges need to be addressed before realization of this vision. PMID- 30294077 TI - Assessment of Functioning of Village Health Nutrition and Sanitation Committees in a District in Maharashtra. AB - Background: Community participation is one of the core principles of primary healthcare. The village health nutrition and sanitation committee (VHNSC), one of the elements in implementation of the National Health Mission (NHM), is an example of community participation. There are not many studies conducted to assess the actual participation of VHNSC in health-care delivery at the village level. Objective: The objective of the study is to develop a VHNSC Maturity Index (VMI) and pilot it to assess the institutional maturity of VHNSC. Materials and Methods: This community-based, cross-sectional study was conducted in 83 villages under four Primary Health Centres (PHCs) of the Wardha Community Development block. VMI was developed, Through several discussion sessions with VHNSC members and staff of the DCM; observations of VHND; attending VHNSC monthly meetings; the VMI was finalized after piloting it in all the four PHC areas. Results: All the 83 VHNSCs were constituted as per norms led down under NHM. Forty-eight (57.8%) VHNSCs had developed an annual Village Health Action Plan, 72 (86.7%) VHNSCs had >=4 meetings held in the past 6 months, and >=70% attendance in the past 6 months was observed in 40 (48.2%) VHNSCs. A majority of 82 (98.8%) VHNSCs helped in organizing the village health and nutrition day, 59 (71.1%) VHNSCs monitored the implementation of national health programs. The entire untied fund received in the previous year was utilized by 68 (81.9%) VHNSCs. Conclusion: The study shows that VMI can be used for continuous monitoring and assessment tool for VHNSC to evaluate and plan different health activities. PMID- 30294078 TI - India has Reached on the Descending Limb of Tobacco Epidemic. AB - Introduction: Till 2016, India was the second largest consumer of tobacco in the world, second only to China. However, in June 2017, the factsheet release of Global Adult Tobacco Survey-2 showed a 6% point decline in the prevalence of tobacco use among adults (>15 years) in the country. Materials and Methods: This is a form of ecological study where trends in aggregate prevalence of tobacco use at country level (using secondary data) were studied in relation to corresponding policy actions over a period of two decades. Results: The results have shown that initial policy actions since the cigarettes act of 1975 till prevention of food adulteration Amendment act of 1995 were largely targeting cigarettes, and so smoking prevalence among men was constantly declining. On the other hand, smokeless tobacco use was increasing among both men and women and reached a peak in 2009-2010. After that, the government took strict policy actions including Food Safety and Standards Authority of India Gutka ban in 2011. There were other persistent efforts, which are discussed in this paper. As a result, a transition has occurred in relation to tobacco epidemic in India. Conclusion: The paper has been concluded with a note that there is no room for complacence and we have a noncommunicable disease action goal to further decline the prevalence of tobacco use in the country to <24.22% by the year 2025. PMID- 30294079 TI - An Epidemiological Study of Blood Pressure and Its Relation with Anthropometric Measurements among Schoolboys of Burdwan Municipal Area, West Bengal. AB - Background: High blood pressure (BP) is often an underdiagnosed problem, because of the asymptomatic nature in early phases of onset during adolescence. This increases the chances of developing complications later during adult life. Objective: The objective of this study was to find the relationship of BP with anthropometric measurements among school-going adolescent boys. Materials and Methods: It was a cross-sectional study conducted among 894 adolescent schoolboys aged 13 to 18 years from July 2013 to October 2014 in schools of Burdwan Municipal area, West Bengal. The required number of students from each school was determined by proportional probability sampling. Then, the required number of students from each school was selected by systematic random sampling technique. BP and anthropometric measurements such as weight, height, and waist circumference were done using standard guidelines. Results: The mean systolic and mean diastolic BP in the study participants was significantly higher with an increase in weight, height, waist circumference, and body mass index (BMI) (P < 0.05). BP was found to be positively correlated with different anthropometric measurements such as weight, height, waist circumference, and BMI, which were statistically significant. Conclusion: Early detection of high BP and application of lifestyle modification among adolescents will be helpful in reducing the burden of high BP in adult life. PMID- 30294080 TI - Relationships between Positive Deviant Behaviors and Children of Normal Growth Pattern in Poorly Resourced Rural Communities. AB - Background: Promotion of positive deviant behaviors (PDBs) can be crucial to bring sustainable change as these behaviors are likely to be affordable and acceptable by the wider community. Objectives: The objective of this study was to assess if any PDBs exist among poorly resourced rural mothers with young children near Vadodara. Materials and Methods: Mothers of children <5 years (n = 160) were enrolled from four rural clusters near Vadodara based on their current growth status (weight-for-age) and were categorized as PD (n = 65) and negative deviant (ND; n = 95), as per the WHO Anthro Software. Personal interviews were conducted through household (HH) visits using a semistructured questionnaire. Data were elicited on HH socioeconomic status, infant and young child feeding practices, diet pattern, and hygiene-sanitation practices. HH dietary diversity score was calculated individually after collecting data through food frequency questionnaire. Results: Mothers had several significant PDBs (P < 0.05), PD group vs. ND group, less use prelacteals to children (53% vs. 71%) and had more exclusive breastfeeding rates (44% vs. 26%), provided cleaner clothing to children (52% vs. 28%), had sufficient intra-HH food distribution (30% vs. 18%), and scored better in dietary diversity at HH level (52% vs. 28%). Conclusions: PDBs and normal growth patterns do exist in poorly resourced areas, and these mothers can be used as "change agents" by the practicing pediatricians of rural communities for improving child health and nutrition.

AB - Context: Elder abuse is a serious problem that has adverse consequence on health. Still, research on elder abuse is sparse in India. Aims: This study aimed to find the nature, prevalence, and factors such as depression and physical problems associated with elder abuse in an urban North Indian community. Materials and Methods: A cross-sectional study was conducted with 222 elders with 97 males, aged 60 years or older residing in an urban community of Delhi. Elders were assessed for abuse by modified Vulnerability to Abuse Screening Scale questionnaire, Geriatric Depression Scale, and self-reported questions on health problems. Results: Mean age of the study population was 66.3 +/- 4.2 years. The overall prevalence of any type of elder abuse was 24.3%. Psychological abuse was the most common type (22.9%) followed by financial abuse (5.8%), physical abuse (1.4%), and anti-constitutional abuse (nil). Among the abused, nearly 20% experienced more than one type of abuse. Thirty-seven women (30%) and 17 men (18%) reported elder abuse. Low income ( 0.05). PTU produced lower amounts of apically extruded debris than WO: SMD = -4.98, Z = 2.79 (P < 0.05). However, results were significantly heterogeneous among all the included studies (I 2= 97%). No significant difference was found between PTU and WO in the amounts of apically extruded debris: SMD = 0.47, Z = 1.06 (P > 0.05). Conclusion: Currently available evidence shows that PTN can produce lower amounts of apical debris than WO (P < 0.05). Moreover, the amounts of apically extruded debris produced by PTU and WO are not significantly different (P > 0.05). Nevertheless, given the limited number of studies reviewed, a definitive conclusion cannot be reached. PMID- 30294106 TI - The internal anatomy of danger zone of mandibular molars: A cone-beam computed tomography study. AB - Aim: The aim of this study was the assessment of the anatomical thickness of danger zone in the cervical third of mesial canals of mandibular molars. Materials and Methods: Fifty mandibular molars were selected and scanned with cone-beam computed tomography. Data were compared using a length tool provided by scanner software. The measured areas were the mesial and distal walls of the cervical third of the mesial roots, which correspond to the safety and danger zones, respectively. In addition, dentin thickness at the furcation was evaluated. Results: Dentin thicknesses of the safety zone were higher than in the danger zone in all teeth examined. The thinnest dentin of the safety zone was found at a point located 4 mm below the canal orifice, with a mean value of 1.03 mm; conversely, in the danger zone, the thinnest point was located 3 mm below the orifice, with a mean value of 0.81 mm. As for the distance from the pulp chamber floor to the furcation, the average value was 2.23 mm. Conclusion: These results show that mean thicknesses at the danger zone of mandibular molar mesial roots were <1.0 mm. These data reinforce the importance of understanding anatomy and the need for conservative preparations when assessing and instrumenting these root canals.

AB - Aim: The purpose of this study is to compare the porosity of two sealant cements, mineral trioxide aggregate (MTA) Fillapex(r) and BioRoot(r) root canal sealer (RCS). These samples were analyzed using microcomputed tomography. Materials and Methods: Sixteen samples were used in the study that were divided according to the composition of the materials used. MTA Fillapex(r) (n = 8) and BioRoot(r) RCS (n = 8) were the samples prepared according to the manufacturer's instructions. They were placed in silicone molds of 5 +/- 0.1 mm in height and an internal diameter of 5 +/- 0.1 mm; 24 h after its preparation, the samples were scanned through a microcomputed tomography, and the porosity results were analyzed statistically by independent t-tests. Results: It is evident that MTA Fillapex(r) has better porosity properties than BioRoot(r) RCS. The results of the study quantify a smaller number of pores per surface, a smaller volume in each pore per mm3, and a lower total porosity present in samples of MTA Fillapex(r) unlike BioRoot(r) RCS samples which is larger in both. Conclusions: The results obtained in computerized microtomography endodontic biomaterial samples concluded that MTA Fillapex(r) has a lower porosity than BioRoot(r) RCS.

AB - Aim: The aim of this randomized, controlled, double-blinded, clinical study is to evaluate and compare the clinical effectiveness of low-level diode GaAlAs laser and glutaraldehyde-based topical desensitizing agent on cervical dentin hypersensitivity with the help of visual analog scale (VAS). Materials and Methods: Fifty teeth of patients aged between 20 and 50 years were included, and VAS was used to assess the dentin hypersensitivity. The teeth were randomly allocated to either Group 1 or 2 using flip coin technique. Group 1 received glutaraldehyde desensitizer and Group 2 received 905 nm low-level laser. The sensitivity scores were recorded, immediately, after1 week and 3 months after therapy. Data was analyzed using Mann-Whitney U test for intergroup comparison and Friedman's test for intragroup comparison. Results: There was a significant reduction in pain in both the groups at 3 months evaluation (P = 0.001).However, Group 2 showed a significant decrease in mean VAS scores when compared with Group 1 at both the one week and three month follow ups (P = 0.04, P = 0.03, respectively). Conclusion: Although topical desensitizer and Low Level Laser are both effective in reducing dentinal hypersensitivity, Low Level Lasers are comparatively more effective at the studied time intervals.

AB - Context: Bleaching can affect the surface properties of resin composites. Aims: The aim of this study was to evaluate the effect of three regimens of carbamide peroxide (CP) on staining susceptibility of silorane and methacrylate-based resin composites. Methods: In this study, 80 composite disks were prepared from A2 shade of P90 and Z250 composite resins (40 each). Samples were divided into three test groups based on the CP concentration (10%, 16%, and 22%) and bleached for 14 days. Controls were kept in distilled water. Then, specimens were immersed in a tea solution for 14 consecutive days. A spectrophotometer was used to measure the specimen colors in CIE L*a*b system, initially and after staining. Data were analyzed using SPSS 16 software using two-way ANOVA, t-test, and Tukey honestly significant difference tests at alpha = 0.05. Results: The color susceptibility of Z250 samples were significantly affected in groups bleached with 22% CP compared to the controls (P = 0.001). The different concentrations of CP did not affect the staining susceptibility of the P90 samples (P > 0.05). Conclusions: Bleaching of the tested resin composites did not increase their susceptibility to extrinsic staining in vitro except for the Z250 samples bleached with 22% CP. PMID- 30294111 TI - Stress distribution in a tooth treated through minimally invasive access compared to one treated through traditional access: A finite element analysis study. AB - Introduction: The purpose of this study was to compare the stress distributions in the teeth treated through minimally invasive access (MIA) designs to those of the teeth treated through traditional straight-line access and their relationship to the final restoration using three-dimensional finite element analysis (FEA). Materials and Methods: Four FEA models of an extracted mandibular first molar were constructed. An intact model served as the control, whereas the other three were prepared with either an MIA or traditional straight-line access. Simulated composite access fillings with or without a simulated gold crown were applied to the models, followed by application of an occlusal load of 100 N. Von Mises stresses in the teeth were then calculated and analyzed. Results: Stress values within the dentin for baseline, MIA with composite filling, MIA with composite filling and crown, and traditional access with composite filling and crown were 10.14 MPa, 6.98 MPa, 11.79 MPa, and 16.81 MPa, respectively. Higher stress values indicate that the tooth is more prone to fracture. Conclusions: A traditional endodontic access cavity may render a tooth more susceptible to fracture compared with an MIA design. PMID- 30294112 TI - Clinical performance of resin-modified glass ionomer cement, flowable composite, and polyacid-modified resin composite in noncarious cervical lesions: One-year follow-up. AB - Background: The restoration of noncarious cervical lesions (NCCLs) often poses a challenge to the clinician. Various restorative materials are available in the market for the restoration of the same. Each material has various advantages and shortcomings. Aim: The aim of this study was to compare and to evaluate the clinical performance of capsulated resin-modified glass ionomer cement (RMGIC), flowable composite, and polyacid-modified composite resin (PMCR) in NCCLs. Materials and Methods: A total of 101 restorations were placed among healthy controls in this clinical trial. A total of 101 restorations were divided into three groups with n = minimum 32 per group (Group 1: 33 restorations, Group 2: 34 restorations, and Group 3: 34 restorations). The restorative materials used were capsulated RMGIC, flowable composite and PMCR. After the placement, the restorations were evaluated for the United States Public Health Services criteria for six parameters, namely retention, marginal adaptation, marginal discoloration, color stability, surface roughness, and sensitivity. The restorations were evaluated at baseline, 6 and 12 months. Statistical Analysis: Statistics was performed using SPSS 21.0 version. Chi-square test was done to compare the proportions between groups. Fisher's exact test was used to compare proportion change between time points. Results: There was no statistically significant difference seen among the three groups for retention, color stability, surface roughness, and hypersensitivity. RMGIC had shown superior characteristics in marginal adaptation and marginal discoloration compared to flowable composite and PMCR, and the difference was statistically significant. Conclusion: Within the limitations of this study, all the three restorative materials are clinically acceptable for the restoration of NCCLs. RMGIC is superior regarding marginal adaptation and esthetics for restoring NCCLs.

AB - Introduction: Dental erosion is defined as the loss of tooth structure due to chemical process that does not involve bacteria. The management of such a condition calls for a comprehensive approach to identifying the cause and treating it. Aim: The aim of this study is to comparatively evaluate the role of grape seed extract (GSE) and cranberry extract (CE) in preventing dental erosion using optical emission spectrometry. Materials and Methods: Prepared enamel specimens were subjected to the erosive challenge using HCl for 10 s, followed by immersion in experimental natural groups and control fluoride group for 30 s and artificial saliva for 60 min. This cycle was repeated three times. The amounts of calcium and phosphorous present in the acid solution after 1st, 2nd, and 3rd erosive challenges were determined for each group using induced coupled plasma optical emission spectrometry. Results: The cumulative calcium and phosphorous release after the 1st, 2nd, and 3rd erosive challenges were found to be the least in SnF2 group, followed by GSE group and then in CE group. Conclusion: The protective of GSE and CE was inferior to the gold standard control group of stannous fluoride role, against enamel erosion. GSE showed better remineralizing effect; however, there was no statistically significant difference between the two groups. PMID- 30294114 TI - Effect of root canal preparation, obturation, and retreatment on the induction of dentinal microcracks: A microcomputed tomography study. AB - Introduction: This study evaluated the effect of root canal preparation, obturation, and different techniques of retreatment on the percentage increase in the number of dentinal microcracks using microcomputed tomography (CT) analysis. Materials and Methods: Forty-five mandibular premolars after micro-CT scanning were prepared using Protaper universal files up to F4 and obturated. After the second micro-CT scanning again, the samples were randomly divided into three groups (n = 15) for retreatment procedure. In Group 1, retreatment was done with Protaper universal D1, D2, and D3 retreatment files followed by Protaper universal file till F4. In Group 2, retreatment was performed with R-Endo reciprocating motion, Re, R1, R2, R3, and Rs followed by Hero Shaper size #40. In Group 3, retreatment was performed with H-files and xylene till size #40. After gutta percha removal, the samples were again scanned for micro-CT for the evaluation of percentage increase in dentinal microcracks. Data were analyzed using "Kruskal-Wallis test ANOVA" and "student t-test" at 5% level of significance. Results: Few unprepared samples showed preexisting microcracks. There were statistically significant percentage increase dentinal cracks after root canal preparation and obturation as well as after retreatment procedure with statistically significant percentage increase in the number of dentinal microcracks between all three groups. Conclusion: Intraradicular procedures such as shaping and cleaning and obturation as well as the use of retreatment file lead to the induction and propagation of dentinal microcracks. In the present study, the maximum microcracks were produced with Protaper universal retreatment file system followed by R-Endo system. H-files produced minimum cracks during retreatment procedures. PMID- 30294115 TI - Cone-beam computed tomographic analysis of middle mesial canals and isthmus in mesial roots of mandibular first molars-prevalence and related factors. AB - Context: The internal anatomy of mandibular first molars has been studied in depth in different populations. However, limited information is present in differentiating a true middle mesial (MM) canal from an isthmus. Aims: The primary aim of this study was to identify the prevalence of a true MM canal and isthmus by retrospectively analyzing cone-beam computed tomography (CBCT) images in vivo. The secondary aim was to determine any correlation between related factors such as sex and age. Materials and Methods: CBCT images of 130 patients with the age group of 13-70 years were selected. Findings of MM canals and isthmus were recorded along with variables such as age and sex. Prevalence was compared using the Chi-square test (P < 0.05). Results: Out of 143 mandibular first molars, the prevalence of the MM canal was 18.2%. There was no statistically significant difference between sex and prevalence of the MM canal and isthmus. The prevalence of isthmi in the mesial roots was 78.4%. Their presence was significantly higher in the apical third area (37.1%) (P < 0.05). Both MM canal and isthmus were seen significantly higher in the age group of 31 50 years (P < 0.05). Conclusions: This study showed a high prevalence of MM canals (18.2%) and isthmus (78.4%). The prevalence of the MM canal and isthmi was significantly higher in the middle age groups. This knowledge may direct the clinicians in locating them leading to good endodontic prognosis.

AB - Aims and Objectives: The aim of this study is to compare the esthetic improvement of white spot lesions (WSLs) treated by icon, sodium fluoride (NaF), and bioactive glass using VITA Easyshade(r) spectrophotometer. Methodology: Ninety intact human maxillary central incisors were collected and artificial WSLs were created on facial surface having dimensions of 4 mm * 4 mm by immersing in demineralized solution for 4 days, baseline comparisons were performed by measuring the color of the WSLs compared to the adjacent sound enamel. All samples were divided into three groups of 30 each. Three groups were Group 1: Treated by NaF, Group 2: Treated by the bioactive glass, and Group 3: ICON(r)-DMG America (Resin infiltration). After treatment, the specimens of all groups were stored in artificial saliva and reevaluated at 4 and 8 weeks after the beginning of the treatments with VITA Easyshade(r) spectrophotometer. Results: Statistical analysis was performed with One-way analysis of variance. Post hoc analysis with the Tukey's honest significant difference test was used to compare the data between the groups. Among three groups, resin infiltration has significant color change (DeltaE) of infiltrated lesions when compared to other treatment groups (P < 0.001). Conclusion: Within the limitations of this study, it can be concluded resin infiltration (ICON(r)) can improve the esthetic characteristics of WSLs. Resin (ICON(r)) is a better treatment option when compared to bioactive glass and NaF as concerned to esthetics. PMID- 30294117 TI - Comparative evaluation of remineralizing efficacy of biomimetic self-assembling peptide on artificially induced enamel lesions: An in vitro study. AB - Background: The biomimetic self-assembling peptide technology is a paradigm for dental hard tissue regeneration. Aim: To investigate the efficacy of biomimetic self-assembling peptide (P11-4) on enamel remineralization compared to casein phosphopeptide-amorphous calcium phosphate fluoride (CPP-ACPF) and fluoride-based delivery systems. Materials and Methods: Artificial enamel lesions were created on buccal surfaces of 40 extracted human molars. Specimens were randomly assigned to four groups (n = 10) according to the remineralizing agent used: G1 - control: artificial saliva, G2 - fluoride varnish, G3 - CPP-ACPF varnish, G4 - self assembling peptide agent. All products were applied according to the manufacturer's instructions and the specimens were stored in daily renewed artificial saliva. Surface microhardness (SMH) was assessed at baseline, after demineralization, after 1 week and after 4 weeks storage. SMH values were analyzed using ANOVA and Tukey's post hoc test. Results: Self-assembling peptide showed the highest statistically significant mean SMH followed by fluoride and CPP-ACPF while the lowest mean SMH was found in artificial saliva. However, no statistically significant difference was found between fluoride and CPP-ACPF. Higher statistically significant mean SMH was found after 4 weeks compared to 1 week remineralization in all groups. Conclusions: Self-assembling peptide confers the highest remineralizing efficacy compared to fluoride and CPP-ACPF, showing a promising, noninvasive regeneration potential. Furthermore, extended period of time helped attain more benefits from the remineralizing regimens applied. PMID- 30294118 TI - Effect of alcoholic beverages on shear bond strength of composites to enamel. AB - Background: Longevity of composite restoration in the oral cavity is dependent on various factors. One such factor is exposure to various foods and beverages which could alter the properties of the material. Aim: The aim of this in vitro study was to evaluate the effect of most widely consumed alcoholic beverages on shear bond strength of composites to enamel. Material and Methods: A total of seventy human premolars were embedded in acrylic resin blocks. Labial enamel surfaces was flattened, etched, bonded, and restored with composite resin (Tetric N Ceram - Ivoclar Vivadent AG, Schaan, Liechtenstein). The specimens were randomly divided into four groups: Group I: beer; Group II: wine; Group III: whiskey, and Group IV: artificial saliva. Group I to Group III were again divided into moderate (Group IA, IIA, and IIIA) and heavy (Group IB, IIB, and IIIB) consumption subgroups. The specimens were soaked in their respective groups for 90 min daily in Group IA, IIA, and IIIA and for 30 min every alternate day in Group IB, IIB, and IIIB until 30 days. Universal testing machine was used to determine the shear bond strength of composite with enamel. Statistical Analysis Used: The values obtained were statistically analyzed using two-way analysis of variance followed by post hoc test with the significant level set at P < 0.05, using GraphPad prism software version 6.01. Results: Group IIB showed the highest reduction in shear bond strength, with a mean value of 6.6 +/- 1.2 Mpa in comparison to control with a mean value of 21.8 +/- 1.6 Mpa. Conclusion: As the content of alcohol and time of exposure increased along with a decrease in the pH of alcoholic beverages, shear bond strength between composite and enamel decreased. PMID- 30294119 TI - Assessment of pain and dissolution of apically extruded sealers and their effect on the periradicular tissues. AB - Aim: This study aimed to evaluate the intensity of pain after unintentional extrusion of resin-based and calcium hydroxide (Ca[OH]2)-based endodontic sealers as well as their influence on the periradicular tissues. Materials and Methods: A total of 120 single-rooted teeth exhibiting extrusion of sealer in the postoperative radiographs were included in the study. According to the sealers used, the teeth were divided into four groups (n = 30): Group I - AH Plus(r), Group II - Resino Seal, Group III - SealapexTM, and Group IV - Apexit(r) Plus. Postoperative pain was assessed at 0-6 h, 6-12 h, 12-24 h, and 24-48 h of obturation using Visual Analog Scale. Radiographs were taken at 3, 6, and >=9 months to 1-year follow-up and compared with baseline radiographs to assess the dissolution of extruded sealers and healing of periradicular tissues. Statistical Analysis: ANOVA, Kruskal-Wallis, and Pearson's Chi-square test were used. Statistical significance level was set at P <= 0.05. Results: Postoperative pain intensity was higher in case of AH Plus(r) sealer followed by SealapexTM up to 12 h of obturation and was statistically nonsignificant. Apexit(r) Plus at all time intervals showed statistically significant less pain intensity than AH Plus(r) and SealapexTM but not from Resino Seal group. At 9-month follow-up, better healing of periradicular tissues was shown by AH Plus(r) (48.1%) followed by Apexit(r) Plus (44.4%) and SealapexTM (41.2%) with statistically nonsignificant difference. Conclusion: In case of periapical extrusion, both resin-based and Ca(OH)2-based sealers caused postoperative pain. Both Ca(OH)2- and resin-based sealers did not influence the treatment outcome.

AB - Context: Noncarious cervical lesions may penetrate the pulp and require root canal treatment followed by crown placement. Such teeth may be susceptible to fracture, especially at the cervical area. Aims: To estimate which combination of restorative material and crown resulted in homogenous stress-strain distribution of endodontically treated abfracted mandibular premolar using three-dimensional finite element model (FEM). Settings and Design: A three-dimensional model of mandibular single-rooted premolar along with alveolar bone was created in finite element analysis (FEA) software preprocessor ANSYS rel 14.5 FEM software (ANSYS Inc., Houston, USA, 1994). Cervical lesion was created in the model with specific dimensions, 3 mm mesiodistally and 2 mm gingivoocclusally with enamel occlusal margin and dentin gingival margin. Materials and Methods: Tooth was simulated to be root canal treated and restored with different types of cements and crowns followed by placing a static load of 300 N at an angle of 135 degrees . Analysis was run and stress distribution pattern was studied. Results: Cervical region of an endodontically treated tooth is subjected to stresses, irrespective of restorative material used. Porcelain fused to metal (PFM) crowns showed least strain values with different postendodontic, restorative materials. Conclusions: FEA is a predictable and reproducible model to predict stress-strain behavior. PFM crowns with different postendodontic restorative materials showed least strain values in the cervical area of abfracted, endodontically treated premolars. PMID- 30294122 TI - Prevention of coronal discoloration induced by root canal sealer remnants using Dentin Bonding agent: An in vitro study. AB - Introduction: Among the various causes of tooth discoloration after root canal treatment, percolation of sealer remnants into the dentinal tubules of the pulp chamber is the most common cause. Objectives: The aim of this study is to evaluate the efficacy of dentin bonding agent (DBA) in preventing coronal discoloration caused by four different root canal sealers- MTA Fillapex, Sealapex, Zical and Z. O. B seal at different time intervals by measuring chromatic alterations using digital images analysis method. Methodology: Ninety mandibular premolars were collected and sectioned at 1 mm below the cementoenamel junction. Standard access cavity preparations of dimensions (depth-3 mm, width 0.8 mm, and length-3 mm) were prepared with a No. 245 bur through the cervical access. Following the standard irrigation protocol, specimens were then randomly divided into nine groups (four groups without DBA [1-4] +4 groups with DBA [5-8] +1 negative control [9]). In Groups 1-4, four different root canal sealers (MTA Fillapex, Sealapex, Zical, and Z.O.B seal) were applied to the walls of the pulp chamber. For Groups 5-8, the samples were etched with 37% phosphoric acid and DBA application was done before the respective root canal sealer application. The cervical access in all specimens was sealed using glass ionomer cement. Digital photographs were taken under standard lighting and environmental conditions at different time intervals: preprocedural, postprocedural, and after 1, 2, 3, and 4 months. These images were analyzed using Adobe Photoshop CS6 from which laboratory values and subsequently Delta E values were obtained. Results: Statistical analysis performed using repeated measures ANOVA and post hoc Tukey's tests show that the groups with DBA application had significantly lower mean Delta E values (P < 0.05) compared to the groups without DBA application. Conclusion: DBAs applied to the dentinal walls of the pulp chamber before obturation can effectively reduce the sealer-induced coronal discoloration. PMID- 30294123 TI - Intracanal heating of sodium hypochlorite: Scanning electron microscope evaluation of root canal walls. AB - Introduction: The aim of this study is to evaluate the surface of root canals dentine using scanning electron microscope (SEM) after instrumentation with rotary Nickel-Titanium systems and two different protocols of activation of sodium hypochlorite (NaOCl) (extracanal heating at 50 degrees C and intracanal heating at 180 degrees C), to assess the presence/absence of smear layer and also the presence/absence of open dentinal tubules along the walls at the coronal, middle, and apical third of each sample. Materials and Methods: Thirty-six single rooted teeth were selected, divided into three groups and shaped with ProTaper Universal instruments following irrigation protocols with 5.25% NaOCl. At the end of the preparation, three different protocols of activation were used: nonheated NaOCl in Group A, extra-canal heated NaOCl at 50 degrees C for Group B and intracanal heated NaOCl at 180 degrees C for Group C. Specimens were cut longitudinally and analyzed by SEM at standard magnification of *1000. The presence/absence of the smear layer as well as the presence/absence of open tubules at the coronal, middle, and apical third of each canal were estimated using a five-step scale for scores. Numeric data were analyzed using Kruskal Wallis and Mann-Whitney U statistical tests and significance was predetermined at P < 0.05. Results: Kruskal-Wallis analysis of variance (ANOVA) for debris score showed significant differences among the Ni-Ti systems (P < 0.05). Mann-Whitney test confirmed that Group A presented significantly higher score values than other Ni-Ti systems. The same results were assessed considering the smear layer scores. ANOVA confirmed that the apical third of the canal maintained a higher quantity of debris and smear layer after preparation of all the samples. Discussion and Conclusions: Intra-canal heating of NaOCl at 180 degrees C proved to be more effective in obtaining clean canal walls. On the other hand, extra canal heating at 50 degrees C of NaOCl left a higher quantity of debris and the smear layer was widely represented.

AB - Invasive cervical resorption of the tooth is a relatively rare and uncommon phenomenon where the etiology remains idiopathic and unclear, and if not treated may lead to ultimate loss of tooth structure. Advancements in digital imaging have made the clinician to diagnose the pathological changes with great precision. Proper diagnosis and management of this condition is key to the successful outcome. The aim of this article was to elaborate two case reports of invasive cervical root resorption with surgical management using biocompatible restorative material. PMID- 30294126 TI - Deducing a surgical dilemma using a novel three dimensional printing technique. AB - Persistent apical periodontitis even after nonsurgical retreatment demands for a surgical approach. This requires a thorough diagnosis and planning to eliminate the pathology and induce healing. This is sometimes challenging when the pathology is present in close relationship to the vital structures. In such cases, modern, sophisticated technology such as three-dimensional (3D) printing can come very handy in patient education as well as for planning and mock-up preparation of the surgery. In this case, a nonhealing persistent apical periodontitis in relation to 16 was surgically treated. However, the pathology was in close association with the maxillary sinus hence fused deposition modeling based 3D printed models were fabricated for patient education and to locate and determine the extent of the lesion. This was followed by the surgical enucleation of the lesion and apicectomy of mesiobuccal and distobuccal roots and mineral trioxide aggregate retro-filling and as the symptoms subsided after the follow-up full coverage metal crown was fabricated and cemented. This technology has opened a new horizon for the use of 3D printing in conjugation with endodontic principles for more predictable endodontic success.

AB - Objective: The present study was aimed to establish a threshold value for cardiac troponin I (cTnI) for nonacute coronary syndrome (ACS) participants from the local population and also to determine the importance of serial time point estimation of cTnI in acute myocardial infarction (AMI), non-ST-elevated MI (NSTEMI), and unstable angina cases. Methods: The present study included 194 cases, admitted in ICCU with the complaint of anginal pain; 31 were diagnosed with AMI with typical electrocardiography (ECG) changes; whereas, 48 cases were diagnosed with NSTEMI. The latter group of cases was selected for the time point study of cTnI release at 0-4 h, 6-12 h, 72 h, and 144 h of admission. cTnI levels were assessed using the Abbott ARCHITECT i1000SR system. Results: ACS was clinically ruled out in 98 cases, and cTnI level for them was used to decide cTnI threshold for the non-ACS group. cTnI level was checked in 17 cases of unstable angina. The threshold value of cTnI for non-ACS participants was 0.1 ng/ml and can be considered as cut-off value for the regional population. The data suggested that the peak of cTnI levels in most of the AMI cases reached during 6 12 h. The cTnI levels were lower than 0.1 ng/ml, and no significant change in ECG was noticed in 17 cases of unstable angina. Conclusion: The present study suggested that the repeat of cTnI assay after 4-6 h of admission is required if the initial value is <3 ng/ml. PMID- 30294128 TI - Non- Neurological Complications after Traumatic Brain Injury: A Prospective Observational Study. AB - Introduction and Aims: Recognizing and treating nonneurological complications occurring in traumatic brain injury (TBI) patients during intensive care unit (ICU) stay are challenging. The aim is to estimate various nonneurological complications in TBI patients. The secondary aim is to see the effect of these complications on ICU stay, disability, and mortality. Materials and Methods: This was a prospective observational study at the neuro-ICU of a Level-I trauma center. A total of 154 TBI patients were enrolled. The period of the study was from admission to discharge from ICU or demise. Inclusion criteria were patients aged >16 years and patients with severe TBI (Glasgow coma score [GCS] <=8). Nonneurological complications were frequent in TBI patients. Results: We observed respiratory complications to be the most common (61%). Other complications, in the decreasing order, included dyselectrolytemia (46.1%), cardiovascular (34.4%), coagulopathy (33.1%), sepsis (26%), abdominal complications (17.5%), and acute kidney injury (AKI, 3.9%). The presence of systemic complications except AKI was found to be significantly associated with increased ICU stay. Most of the patients of AKI died early in ICU. Respiratory dysfunction was found to be independently associated with 3.05 times higher risk of worsening clinical condition (disability) (P < 0.018). The presence of cardiovascular complications during ICU stay (4.2 times, P < 0.005), AKI (24.7 times, P < 0.02), coagulopathy (3.13 times, P < 0.047), and GCS <6 (4.2 times, P < 0.006) of TBI was independently associated with significantly increased risk of ICU mortality. Conclusion: TBI patients tend to have poor outcome due to concomitant nonneurological complications. These have significant bearing on ICU stay, disability, and mortality. PMID- 30294129 TI - Targeted-Volume Noninvasive Ventilation Reduces Extubation Failure in Postextubated Medical Intensive Care Unit Patients: A Randomized Controlled Trial. AB - Purpose: Till date, the benefit of using noninvasive ventilation (NIV) routinely after extubation to prevent reintubation has been conflicting. We aim to demonstrate the effect of targeted-volume NIV for the prevention of reintubation and extubation failure after planned extubation in medical intensive care unit (ICU) patients. Study Design: This was a prospective, randomized controlled study. Materials and Methods: Patients on invasive mechanical ventilation for more than 48 hrs for acute respiratory failure, who were ready for extubation, were randomized into targeted-volume NIV (intervention group) or oxygen mask (controlled group) immediately after extubation and continuously for 24 hrs. Results: A total of 58 patients were enrolled in this study. The targeted-volume NIV group was observed to have a trend toward lower reintubation rate within 48 hrs compared to oxygen mask group (0% vs. 17.2%; P = 0.052). Extubation failure rate within 48 hrs was significantly lower in targeted-volume NIV group compared to oxygen mask group (0% vs. 41.38%; P < 0.001). There was a trend toward lower ICU length of stay (6[5] days vs. 10[8] days (median interquartile range [IQR]); P = 0.053) as well as shorter hospital length of stay after extubation (10[19] days vs. 18[15] days (median [IQR]); P = 0.059). There were no differences in the incidence of ventilator-associated pneumonia (VAP)/hospital-acquired pneumonia (HAP) (6.90% vs. 20.69%;P = 0.253) and 28 day-mortality (13.79% vs. 20.69%; P = 0.487). Conclusions: Our study is the first study to demonstrate the benefit of application of targeted-volume NIV immediately after extubation in reducing extubation failure rate. There was a trend toward lowering reintubation rate and shorter ICU length of stay and hospital length of stay after extubation in mixed medical ICU patients. PMID- 30294130 TI - Sonographic Measurement of Optic Nerve Sheath Diameter: How Steep is the Learning Curve for a Novice Operator? AB - Background: Transbulbar sonography for measuring optic nerve sheath diameter (ONSD) is noninvasive bedside technique for detection of raised intracranial pressure. This study aims to evaluate the number of sonographic evaluations required for a novice operator to learn proper measurement of ONSD after a formal training and supervised scanning session. Methods: Three novice operators and one expert operator measured ONSD of 27 healthy volunteers using linear array transducer HFL38x (frequency range of 6-13 MHz) (MicroMaxx(r); SonoSite, USA). In each eye, ONSD was measured three times by each observer and mean value was determined. Correlation coefficient was calculated between the novice and the experienced operator and in between the novice operators. Number of scans, after which the significant correlation developed between novice and the experienced operator and between the novice operators, was analyzed. Results: Cronbach's alpha was tested to evaluate the reliability of the values obtained from intra- and interobservations. For all 27 cases, the value of Cronbach's alpha was high: 0.80-0.99 for the right eye and 0.69-0.97 for the left eye. The mean interobserver variations were plotted on a graph which fluctuated largely in the first 17 cases but oscillated around 0.5-0.30 in the last 10 cases. Conclusion: Learning curve for novice operators to measure ONSD is steep and they can be taught to measure ONSD in healthy volunteers by sonography in supervised clinical session with an acceptable clinical precision and accuracy comparable to an experienced operator. PMID- 30294131 TI - Evaluating Extravascular Lung Water in Sepsis: Three Lung-Ultrasound Techniques Compared against Transpulmonary Thermodilution. AB - Background: Excessive extravascular lung water (EVLW) is associated with increased morbidity and mortality. We compared three lung-ultrasound (L-US) techniques against the reference-standard transpulmonary thermodilution (TPTD) technique to access EVLW. Materials and Methods: This was a prospective, single blind, cross-sectional study. Forty-four septic patients were enrolled. EVLW index was measured by the TPTD method, and an index of >=10 mL/kg was considered diagnostic of pulmonary edema. EVLW index was then compared to three established bedside L-US protocols that evaluate sonographic B-lines: (1) a 28-zone protocol (total B-line score [TBS]) (2) a scanning 8-region examination, and (3) a 4-point examination. Results: Eighty-nine comparisons were obtained. A statistically significant positive correlation was found between L-US TBS and an EVLW index >=10 mL/kg (r = 0.668,P < 0.001). The 28-zone protocol score >=39 has a sensitivity of 81.6% and a specificity of 76.5% to define EVLW index >=10 mL/kg. In contrast, the positive 4-point examination and scanning 8-regions showed low sensitivity (23.7% and 50.0%, respectively) but high specificity (96.1% and 88.2%, respectively). Ten patients with a total of 21 comparisons met criteria for acute respiratory distress syndrome (ARDS). In this subgroup, only the TBS had statistically significant positive correlation to EVLW (r = 0.488,P = 0.025). Conclusion: L-US is feasible in patients with severe sepsis. In addition, L-US 28 zone protocol demonstrated high specificity and better sensitivity than abbreviated 4- and 8-zone protocols. In ARDS, the L-US 28-zone protocol was more accurate than the 4- and 8-zone protocols in predicting EVLW. Consideration of limitations of the latter protocols may prevent clinicians from reaching premature conclusions regarding the prediction of EVLW. Trial Registration: ISRCTN11419081. Registered 4 February 2015 retrospectively. PMID- 30294132 TI - Survey on Perceived Impact of Religion, Culture, and Social Network Information on Surrogate Decision-making in a South Asian Developed Country. AB - Introduction: Relatives often have to assume responsibility for making end of life choices as surrogate decision-makers for patients with diminished or are lacking capacity. Our aim was to study the influence of religion, culture and social network information on surrogate decision making. Methods: This study was an exploratory, prospective, survey. Questions addressed the role of surrogates in decision making and the importance and influence of religion, culture and social media on such decisions. Results: 34 respondents filled out the anonymous survey. Surrogate decision making is a complex process and influenced by many factors. Conclusion: This survey points to a need for wider studies looking at the factors influencing people when making such important decisions and further social psychology interventions to evaluate whether such decisions can be made more consistent and patient centred. PMID- 30294133 TI - Diagnostic and Prognostic Role of Neutrophil-to-Lymphocyte Ratio in Early and Late Phase of Sepsis. AB - Objective: Early diagnosis of sepsis is necessary to decrease morbidity and mortality. This study aims to evaluate neutrophil-to-lymphocyte ratio (NLR) as diagnostic and prognostic of early and late phase of sepsis. Methods: It was a prospective, observational study, conducted in Intensive Care and High Dependency Unit (Daycare) of the Department of Pulmonary and Critical Care Medicine (tertiary care center), Rohtak, from January 2017 to December 2017. A total of 56 cases of newly diagnosed cases of sepsis were included in the study and 20 healthy adults were taken as controls. Daily NLR was calculated in cases till the primary outcome. Results: The results suggested that NLR seems to have promising role as diagnostic and prognostic marker (with P = 0.001 and P = 0.045, respectively) in sepsis. Conclusion: The study suggests that NLR can be a useful diagnostic and prognostic marker in sepsis. PMID- 30294134 TI - Hypernatremia due to Urea-Induced Osmotic Diuresis: Physiology at the Bedside. AB - Hypernatremia secondary to urea-induced solute diuresis is due to the renal excretion of electrolyte-free water. This concept is explained here step-wise physiologically with the help of a clinical vignette. PMID- 30294135 TI - Hepatitis A Virus-induced Severe Hemolysis Complicated by Severe Glucose-6 Phosphate Dehydrogenase Deficiency. AB - Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an x-linked recessive genetic disorder with mutation in the G6PD gene. Defect in the enzyme G6PD causes red blood cells (RBCs) to breakdown prematurely causing hemolytic anemia. Hemolytic anemia is also a known hematological complication associated with viral hepatitis. In such patients, hemolysis may be more severe if there is any secondary injury to RBC in the form of membrane defect, oxidative stress, or enzyme deficiency like in G6PD deficiency. Here, we present a case of an adult, not previously diagnosed with G6PD deficiency, who presented with viral hepatitis, severe hemolysis, and multiorgan failure. PMID- 30294136 TI - Severe Hypokalemia Mimicking Brain Death. AB - We discuss a case of a 20-year-old female who presented with history of fever, vomiting, and decreased oral intake for 10 days followed by one episode of generalized tonic-clonic seizure and altered sensorium for 5-6 h. On arrival in the emergency room, she had Glasgow Coma Scale 3 (E1V1M1), both pupils fixed and dilated, low blood pressure, low oxygen saturation, and few gasping breaths. She appeared to be brain dead and was assumed to have a very poor prognosis. Investigations revealed severe hypokalemia. She had also suffered acute hypoxic ischemic injury to the brain. However, she recovered and was discharged about 2 weeks later. PMID- 30294137 TI - A Rare Case of Localized Tetanus. AB - Tetanus is a severe and potentially fatal infection caused by the bacterium Clostridium tetani. Presentations of tetanus include generalized tetanus, neonatal tetanus, cephalic tetanus, and localized tetanus, the latter two being much rarer. We present case of a 55-year-old male farmer, presented with an injury to the left toe. A surgical wound exploration and washout with administration of human tetanus immunoglobulin and tetanus toxoid were given as treatment with antibiotic support. This case report points out the importance of the early recognition of a rare form of this fatal infectious disease, which may present with prodromal symptoms before the generalized form shows its clinical effects. Successful management includes prompt diagnosis, neutralization of circulating toxin and elimination of C. tetani infection, control of spasms, maintenance of the airway, and management of respiratory failure and autonomic dysfunction. PMID- 30294138 TI - Verapamil as an Adjuvant Treatment for Drug-Resistant Epilepsy. AB - Almost one-third of the people suffering from epilepsy continue to have seizures in spite of using appropriate antiepileptics. Pharmacoresistance is defined as the failure to achieve seizure control with two or more anticonvulsant medications at appropriate daily dosage. Here, we discuss one such gentleman whose seizures had been intractable despite multiple antiepileptic drugs in maximum tolerable doses. Verapamil, a calcium channel blocker, was used for its P glycoprotein inhibition properties to overcome the pharmacoresistance in this patient with satisfactory seizure control. There are a few studies with limited patients on the successful usage of verapamil in a patient with pharmacoresistant status epilepticus (SE). We intend to publish this case report to draw interest among the critical care physicians on pharmacoresistant SE, the different hypotheses that prevail, its causes and the available management strategies.

AB - After more than three decades of access to low-cost liquefied petroleum gas (LPG) financed by large direct government subsidies, more than 90% of Ecuadorian households cook primarily with LPG. Due to the large fiscal burden of the LPG subsidy, increases in electricity from hydropower, and other sociopolitical factors, the Government of Ecuador launched a major induction stove program (PEC) to reduce the demand for LPG. We assess the effects of the LPG subsidies and PEC using government records, interviews, academic literature, newspaper reports, household surveys, and focus groups. Household surveys, conducted in rural, northern Ecuadorian households (n=383), characterized cooking patterns and fuel access. Focus groups (n=6) were carried out with a subset of surveyed households to better characterize survey findings. The LPG subsidy was developed as part of broad social support reforms in the early 1970s, without specific aims to reduce the health impacts of household air pollution from woodfuel or provide economic benefits as part of the transition to a clean cooking fuel. Nonetheless, the subsidy has resulted in nearly all Ecuadorian households cooking primarily with LPG. PEC has generated the sale of 740,000 induction stoves since its inception in 2014, short of the goal of 3.5 million. Among the rural households surveyed, LPG use, acceptance, and satisfaction was high, however, more than three-quarters of those surveyed reported weekly woodfuel use. Induction stove ownership (17%) and use as a primary cooking fuel (1%) was low among the rural households surveyed; furthermore, households owning induction stoves reported very low satisfaction with the stoves. Here we show that nationally-representative surveys reporting only "primary cooking fuef" use may underestimate solid fuel use as a supplemental household cooking energy, particularly in rural areas where fuel availability issues play a stronger role in decisions about what fuels to use. PMID- 30294144 TI - A Comparison of Oral Midazolam-ketamine, Dexmedetomidine-fentanyl, and Dexmedetomidine-ketamine Combinations as Sedative Agents in Pediatric Dentistry: A Triple-Blinded Randomized Controlled Trial. AB - Introduction: It is common to encounter a patient who is anxious to the magnitude that precludes the possibility of provision of dental treatment. This study aims to evaluate and compare the sedative effect of oral combinations of midazolam ketamine (MK), dexmedetomidine-fentanyl (DF), and dexmedetomidine-ketamine (DK) in a group of uncooperative children requiring dental treatment. Methodology: This was a prospective, randomized, triple-blind study where 36 children who were 3-9 year old with American Society of Anesthesiologists -I status and presenting early childhood caries were randomly assigned to: Group A - 0.3 mg/kg of M and 5 mg/kg K, Group B - 2 ug/kg of D with 3 ug/kg of F, and Group C - 2ug/kg of D with 5 mg/kg of K in 1 mL honey. Patients' blood pressure, heart rate, and oxygen saturation were recorded from the start of the procedure till discharge. Patients' behavior, sedation status, and wake-up behavior were evaluated with Modified Observer Assessment of Alertness and Sedation Scale and ease of treatment completion by Houpt scale. Results: Hemodynamic changes were statistically insignificant in all three groups. 72.8% of patients in Group A and 58.3% of patients in Group B were successfully sedated during treatment. Behavior improvement was seen in all three groups during treatment with statistically insignificant difference in behavior scores produced by Group C. Ease of treatment completion was moderately better with Group A. Conclusion: Oral DK has a comparable sedative property with oral MK combination. Oral DF promises to be a potential sedative agent for children due to its successful anxiolysis. PMID- 30294145 TI - Comparative Evaluation of Antimicrobial Efficacy of Silver Nanoparticles and 2% Chlorhexidine Gluconate When Used Alone and in Combination Assessed Using Agar Diffusion Method: An In vitro Study. AB - Context: Silver nanoparticle (AgNP) is a potent antimicrobial that is widely used in several fields of medicine. Chlorhexidine (CHX) gluconate is a well-known agent used in dentistry to eliminate oral microbial flora. Aims: The aim of this study is to evaluate the efficacy of AgNPs, 2% CHX gluconate, and the combination of two solutions against endodontic pathogens such as Enterococcus faecalis, Klebsiella pneumoniae, and Candida albicans. These organisms are frequently found in the root canal space and their persistence may lead to endodontic failure. The synergistic effect of the two solutions has been evaluated in this study. The antibiotic gentamycin was taken as the control group. Settings and Design: Agar well diffusion method was used and minimum inhibitory concentration of AgNP was found to be 15 MUg/mL. AgNPs were synthesized from the aqueous plant extract of Cassia roxburghii. The combination of CHX-AgNP solution was stirred together by a glass rod. The values were tabulated and subjected to statistical analysis using the SPSS software version 20. One-way ANOVA test was used to compare within the groups and between groups. The level of significance was set at 5%. Results: CHX AgNP combined solution exhibited the highest efficacy in comparison to these solutions used alone. They showed the highest efficacy against C. albicans among the three organisms tested. Conclusion: The present study demonstrates the antimicrobial efficacy of a novel mixture of CHX-AgNP solution, and it may be developed as a promising antimicrobial agent against endodontic flora. PMID- 30294146 TI - Evaluation of Serum Leptin and Adiponectin in Obese Individuals with Chronic Periodontitis. AB - Objectives: Studies have reported changes in leptin and adiponectin levels in the gingival crevicular fluid, saliva, and blood serum of obese patients with periodontal disease. The aim of the study is to evaluate serum leptin and adiponectin levels in obese and nonobese individuals with chronic periodontitis and to deduce a relationship between the clinical parameters and the inflammatory biochemical parameters. Materials and Methods: In this case-control study, a total of fifty individuals were selected based on the body mass index (BMI): Group I of obese individuals with chronic periodontitis and Group II of nonobese individuals with chronic periodontitis. Periodontal parameters used in this study were plaque index, gingival index, probing pocket depth, and clinical attachment level. The effects of obesity and periodontal status on serum leptin and adiponectin levels of both groups were statistically analyzed using an independent t- test. Results: Statistical analysis showed that the effect of BMI on serum leptin and adiponectin levels was statistically significant (P < 0.01), and the effect of chronic periodontitis on the serum leptin and adiponectin levels was also statistically significant compared to nonobese individuals (P < 0.0001). However, there is no statistically significant correlation between serum leptin and adiponectin, which indicates that both are independent to each other. Conclusions: In obese individuals with chronic periodontitis, serum leptin levels were significantly high compared to nonobese individuals and serum adiponectin levels were significantly lower in obese individuals compared to nonobese individuals with periodontitis, though both the parameters were independent of each other. PMID- 30294147 TI - Comparative Evaluation of Apical Transportation and Canal Centric Ability in Apical Region of Newer nickel-titanium File Systems Using cone-beam computed tomography on Extracted Molars: An In Vitro Study. AB - Background: Objective in root canal preparation is to develop a shape that tapers from apical to coronal, maintaining the original canal shape. With advent of instruments manufactured from nickel-titanium (NiTi) alloys, there was a significant improvement of quality of root canal shaping, with predictable results and less iatrogenic damage. Aim: The aim of the study was to evaluate the canal centric ability and apical transportation in apical region of newer NiTi file system in root canal using cone-beam computed tomography (CBCT) on extracted molars. Materials and Methods: Root canal of thirty extracted human permanent teeth with mature root apices with 20 degrees -40 degrees of curvature were collected and divided into three groups after initial bio-mechanical preparation: Group 1: canal prepared using ProTaperNext (PTN) file system; Group 2: canal prepared using Mani silk system; and Group 3: canal prepared using V-taper file system. All samples were scanned before and after biomechanical preparation using CBCT. The data collected were evaluated using the Kruskal-Wallis analysis of variance test and Mann-Whitney U-test. Results: It was observed that in apical region Group I (PTN) showed significantly lower mean apical transportation and canal centric ability as compared to Group II (Mani Silk) and Group III (V taper). Conclusion: It was concluded that PTN rotary system has no canal transportation and maintained centric ability in comparison to Mani and V-taper rotary file system in apical region of curved root canal.

Results: Prevalence found by using panoramic radiography is 1.96% and by using CBCT is 12.5%. Conclusions: This research scrutinizes the prevalence of pneumatized articular tubercle and establishes the prevalence of the same among the studied population, using panoramic radiography and CBCT. PMID- 30294149 TI - Evaluation of Antimicrobial Efficacy of Nanosilver Solution, Sodium Hypochlorite and Normal Saline in Root Canal Irrigation of Primary Teeth. AB - Background: Bacteria are the main etiological factors in the development of dentinal caries and its progression to pulpal and periapical disease. Enterococcus faecalis is the bacterial species most frequently recovered from the root-filled teeth. Aim: This study aimed to evaluate the antimicrobial effectiveness of nanosilver (NS) solution as an endodontic irrigation solution of primary teeth against E. faecalis. Settings and Design: Thirty-six canals of primary teeth were selected for this ex vivo study. Methods and Materials: Thirty six canals of primary teeth were prepared up to the file #35 and all of the specimens were sterilized. Then, root canals were inoculated with a suspension containing E. faecalis bacteria. The teeth were then randomly divided into three groups. Antimicrobial effectiveness was evaluated immediately after dividing into groups by counting colony-forming units on brain heart infusion broth plates. Statistical Analysis: Data were analyzed using Kolmogorov-Smirnov, Welch, and Dunnett's T3 tests. Results: Sodium hypochlorite showed the highest antimicrobial effectiveness against E. faecalis and showed significant differences compared with normal saline and NS solution (P < 0.001). Conclusion: Based on the results of this study, solution of NS particles can be used as an alternative to other root canal irrigating solutions. PMID- 30294150 TI - Comparative Evaluation of Retention, Cariostatic Effect and Discoloration of Conventional and Hydrophilic Sealants - A Single Blinded Randomized Split Mouth Clinical Trial. AB - Introduction: Pit and fissures are approximately eight times vulnerable than the smooth surface caries lesion. Sealants are effective in preventing, arresting, and progression of pit-and-fissure occlusal caries lesions. The failure of sealant resin-based retention is mainly attributed to the moisture contamination. To overcome this drawback, UltraSeal XT(r) hydro, a moisture-friendly sealant, has been introduced. Aim: This study aimed to compare and evaluate the retention, cariostatic effect, and discoloration of conventional ClinproTM 3MTM ESPETM and hydrophilic UltraSeal XT(r) sealants among 12 to 15-year-old schoolchildren for 3 months. Materials and Methods: A single-blinded, randomized, split-mouth clinical trial was conducted among thirty schoolchildren aged 12-15 years. Sealants used in the present study were Group I - ClinproTM and Group II - UltraSeal XT(r) hydro. Sealants were provided in the school by two operators based on the computer-generated random sequence and the study participants were evaluated after 3 months for sealant coverage, caries incidence, and discoloration using Color, Coverage and Caries sealant evaluation system. Sealant coverage between the two sealants was compared using Mann-Whitney U-test and Z-test for proportions. Results: A total of 47 teeth (78.3%) with UltraSeal XT(r) Hydro had the sealant covering in all the fissures compared to ClinproTM 3MTM ESPETM which was 46.7% (28 teeth) and the difference was observed to be statistically significant. Conclusion: Hydrophilic UltraSeal XT(r) Hydro yielded better sealant coverage (retention) compared to the conventional ClinproTM 3MTM ESPETM. No difference was observed with regard to cariostatic effect and discoloration. PMID- 30294151 TI - Evaluation of Marginal Adaptation of a Self-Adhering Flowable Composite Resin Liner: A Scanning Electron Microscopic Study. AB - Background: "Self-adhering composite resins," are claimed to eliminate the need for a separate acid etching and bonding agent application step, thus simplifying the direct restorative procedure, both regarding the technique sensitivity and the duration of treatment. Aim: The aim of this study is to evaluate the marginal adaptation of self-adhering flowable composite (Dyad flow) in comparison to the conventional flowable composite (Tetric N-flow) under scanning electron microscope (SEM). Settings and Design: This in vitro study was conducted on 44 extracted human maxillary premolars. Materials and Methods: Box-only Class II cavities on the distal surface were prepared with the dimensions of 4 mm buccolingual width, 2 mm mesiodistal depth, and gingival margin at the cementoenamel junction. They were divided into two groups of 22 teeth each and were restored accordingly: Group I - Gingival floor lined with Tetric N-Flow and were restored with Tetric N-Ceram; Group II - Gingival floor lined with Dyad flow and were restored with Herculite Precis. After thermal cycling, the sectioned tooth-restoration interfaces were evaluated for the marginal adaptation under SEM at *200 magnification. Statistical Analysis Used: The resultant data were statistically analyzed by applying Chi-square test, using the SPSS (version 16.0) software. Results and Conclusion: There was no statistically significant difference between the study groups regarding the marginal adaptation. The marginal adaptation of the self-adhering flowable composite when used as a liner in Class II restorations was comparable to that of the conventional flowable composite. PMID- 30294152 TI - Molar Incisor Hypomineralization and Its Prevalence. AB - Background: Molar incisor hypomineralization (MIH) is the hypomineralization of systemic origin of one to four permanent first molars, frequently associated with affected incisors. It is presented as demarcated enamel opacities of different colors, occasionally undergoing posteruptive breakdown. The characteristic feature of MIH is the clear demarcation between the affected and sound enamel. There is asymmetry of defects present in the molars and incisors where one molar or incisor can be severely affected, while the contralateral tooth may be clinically sound or have only minor defects. Aim and Objective: The aim of this study is to evaluate schoolchildren of 7-12 years of age with at least one of the first permanent molars fully or partially erupted from randomly selected government and private schools in Chennai using the European Academy of Pediatric Dentistry (EAPD) criteria for MIH, to determine the prevalence and characteristics of MIH. Materials and Methods: The dental examinations were performed in the classroom using a mouth mirror and explorer under a headlight. Teeth were wiped with gauze when necessary to remove plaque or the food accumulations. Surfaces that were examined were the buccal, lingual, palatal, and occlusal surfaces of permanent first molars and labial surfaces of upper and lower incisors. A single examiner was involved to avoid interexaminer bias. All the data were collected and scored using the EAPD criteria for MIH. Results: A total of 22 (12.9%) children out of the examined 170 had MIH. Conclusion: Distribution of MIH was more in males, more in 9 years of age. A total of 13 children had first molars affected and 9 children had both incisors and molars affected. Molars were affected more than the incisors. Mandible was affected more in comparison with the maxilla. Right side was affected more than the left side. The distribution of MIH was more in government schools compared to private schools. PMID- 30294153 TI - Physical Properties of Heat Cure Denture Base Resin after Incorporation of Methacrylic Acid. AB - Introduction: Heat cure acrylic resins are the most commonly used denture base materials. The important limitation is they may act as reservoir of microorganisms. The adherence of microorganisms can be reduced by chemical modification of the surface charge of denture base resin. Incorporation of methacrylic acid (MA) in the denture base resin gives a negative surface charge. A denture base having a negative surface charge may hinder the initial adhesion of microorganisms through repulsive electrostatic forces. Aims and Objectives: The present in vitro study was performed to determine the effect of addition of antimicrobial agent MA on the flexural strength and surface roughness of heat cure denture base resin. Materials and Methods: A total of 90 heat cure acrylic specimens were prepared. Of 90 specimens, 30 were prepared as Group I control group without addition of MA. Groups II and III specimens were prepared by adding 10% and 20% MA, respectively. Using universal testing machine and surface roughness tester, flexural strength and surface roughness of specimens measured. Results: In the present study, decrease in the flexural strength was observed when the concentration of the MA increased in the denture base resin. A slight increase in the surface roughness was observed as the concentration of MA increased. PMID- 30294154 TI - Burning Mouth Syndrome: A Comparative Cross-sectional Study. AB - Background and Aim: Burning mouth syndrome (BMS) may be defined as a burning sensation in the oral mucosa usually unaccompanied by clinical signs. Multiple conditions have been attributed to a burning sensation. The aim of this study was to determine the role of age and sex in BMS. Materials and Methods: A total of 195 consecutive patients with BMS and 95 healthy patients without burning sensation were recruited in this study. Patients with BMS had experienced oral, burning sensations for at least 6 months without oral clinical signs, and with a normal blood count. Multiple logistic regression analyses were utilized to define the main predictors. Results: Menopause, candidiasis, psychological disorders, job status, denture, and dry mouth were significantly frequent in BMS patients. Multivariate logistic regression indicated age (odds ratio (OR) =1.12, 95% confidence interval (CI): 1.08-1.15, P < 0.0001) and sex (OR = 3.14, 95% CI: 1.4 6.7, P < 0.002) significantly increase the odds of BMS. Psychological disorders (OR = 3.39, 95% CI: 1.2-9.5, P < 0.02) and candidiasis remain as predictive factors. Ultimately, age was defined as a critical predictor. Moreover, we can therefore predict that a 60-year-old woman with psychological disorders is 25 times more likely to suffer from BMS than a man 10 years younger who has no psychological disorder. Conclusion: Age and sex were the main predictors in BMS. Psychological disorders and candidiasis were significantly associated with the occurrence of BMS.

AB - Objective: The objective of this study is to compare the apical sealability of mineral trioxide aggregate (MTA) Fillapex and Endosequence BC sealer at three different lengths of remaining gutta-percha after postspace preparation. Materials and Methods: A total of 80 freshly extracted human maxillary anterior teeth were decoronated, biomechanically prepared, and randomly divided into four groups; Group A and Group B served as positive and negative control with 10 teeth each. The teeth in Group C and Group D (with 30 teeth each) were obturated with gutta-percha using MTA Fillapex sealer and Endosequence BC sealer, respectively. Teeth in Group C and Group D were further subdivided into three subgroups depending on the length of remaining apical gutta-percha, i.e., 3, 4, and 5 mm after postspace preparation. Apical leakage was assessed using dye penetration method under stereomicroscope. Results: In both the Groups C and D, there was overall no statistically significant difference in leakage; however, Group C showed slightly more leakage than Group D. There was a statistically significant difference in leakage at 3 mm and 5 mm level in both groups. Conclusion: Although less microleakage occurred, the bioceramic sealers could not totally eliminate leakage.

AB - Objectives: The aim of this study was to evaluate the effect of calcium-based desensitizers on the microleakage with and without preetching enamel in Class V cavities restored with all-in-one adhesives. Materials and Methods: Class V cavities were prepared on the buccal surfaces of 100 extracted human premolars. A total of 100 box-shaped cavities were divided into five groups (n = 20). Group 1 no desensitizer was applied and Groups 2 and 4 - desensitizer (CCP-ACP and Novamin) was applied, respectively, followed by the application of G-Bond and restored with composite restoration. Groups 3 and 5 are same as Group 2 and 4, but preetching of enamel was done for 3 s after desensitizers application. The teeth were thermocycled and the specimens were examined for microleakage using methylene blue as a marker. The teeth were sectioned buccolingually and evaluated for microleakage under stereomicroscope and the scores obtained were analyzed with Kruskal-Wallis and Mann-Whitney tests. Results: Statistically significant difference existed between Groups 2 and 3 (P < 0.05). There was also statistically significant difference between Groups 4 and 5 (P < 0.05). Groups 3 and 5 showed significantly less microleakage (P < 0.05). No statistically significant difference in microleakage values was observed between the two desensitizers CCP-ACP and Novamin. Conclusion: The application of calcium containing desensitizers with selective etch enamel technique in all-in-one adhesives could be considered an advisable procedure to minimize microleakage. PMID- 30294157 TI - Efficacy of Intraosseous Local Anesthesia for Restorative Procedures in Molar Incisor Hypomineralization-Affected Teeth in Children. AB - Background: Treatment of teeth affected with molar incisor hypomineralization (MIH) in young patients is challenging due to chronic subclinical pulpal inflammation caused by porous enamel and exposed dentin. Hypersensitivity of the teeth and difficulty in achieving local anesthesia due to altered nerve potential affects the successful completion of the treatment. Aim: The aim of the study was to compare the anesthetic efficacy of the intraosseous (IO) anesthetic technique with conventional local infiltration technique in anesthetizing first permanent molars (FPMs) affected by MIH for restorative procedures in children. Materials and Methods: This randomized controlled clinical trial recruited 54 MIH-affected mandibular or maxillary FPMs requiring restorations or stainless steel crowns. The teeth were randomly allocated to two equal groups to receive either IO injection or buccal infiltration (control), both using 4% articaine. Onset, time required, and pain experienced for administration, need for repeat, efficacy of anesthetic technique, heart rate, and postoperative complications were recorded in both the groups. Collected data were subjected to statistical analysis. Results: Onset was significantly faster and pain experienced during administration was significantly lower with IO technique. Need for repeat of anesthesia was significantly more with infiltration (44.4% vs. 7.4% in IO, P = 0.004). Local infiltration failed to produce profound anesthesia in 74.1% MIH affected teeth. IO anesthesia profoundly anesthetized 88.9% MIH-affected teeth. Anesthetic efficacy was significantly better with IO anesthesia (P < 0.001). Postoperative complications were significantly lower with IO anesthesia (P = 0.003). Conclusion: IO local anesthesia was found to be an effective and safe technique to achieve profound anesthesia in MIH-affected teeth in children in comparison to local infiltration. PMID- 30294158 TI - Assessment of Survival Rate of Dental Implants in Patients with Bruxism: A 5-year Retrospective Study. AB - Background: Dental implants are associated with failure such as early or late failure. Systemic conditions such as diabetes, hypertension, and bruxism affect the success rate. The present study was conducted to assess complications in dental implants in bruxism patients. Materials and Methods: This 5-year retrospective study was conducted on 450 patients (640 dental implants) who received implants during the period and followed up for 5 years from June 2010 to June 2016. Among these patients, 124 had bruxism habit. Dental radiographs or patients' recalled records were evaluated for the presence of complications such as fracture of implant, fracture of ceramic, screw loosening, screw fracture, and decementation of unit. Results: In 240 males and 210 females, 380 implants and 260 implants were inserted, respectively. The difference was statistically nonsignificant (P = 0.1). A total of 145 screw-type and 130 cemented-type fixations had complications. The difference was statistically nonsignificant (P = 0.5). Complications were seen in single crown (45), partial prostheses (125), and complete prostheses (105). The difference was statistically significant (P = 0.012). The common complication was fracture of ceramic (70) in cemented-type fixation and fracture of ceramic (85) in screw-type fixation. The difference was statistically significant (P = 0.01). Forty-two single crowns showed decementation, 85 partial prostheses had fracture of ceramic/porcelain, and 50 complete prostheses showed fracture of ceramic/porcelain. The failure rate was 42.9%. Survival rate of dental implants in males with bruxism habit was 90% after 1 year, 87% after 2 years, 85% after 3 years, 75% after 4 years, and 72% after 5 years. Survival rate of dental implants in females with bruxism habit was 92% after 1 year, 90% after 2 years, 85% after 3 years, 75% after 4 years, and 70% after 5 years. The difference among genders was statistically nonsignificant (P = 0.21). Conclusion: Bruxism is a parafunctional habit which affects the survival rate of dental implants. There is requirement to follow certain specific protocols in bruxism patients to prevent the developing complications. PMID- 30294160 TI - Dermatoglyphic Analysis in Parents with Cleft Children: A Comparative Study. AB - Background and Objective: There were studies in the literature which showed the altered dermatoglyphics in the cleft children. But it would be beneficial if probable expression can be proved in prior generations, so that genetic counseling and other preventive measures can be undertaken. The aim of the study is to determine variations in dermatoglyphics of prior generations which would serve as bench markers to predict the occurrence of cleft in off springs. Materials and Methods: A total of 400 parents aged between 25-45 years were selected and divided into two groups - Group A consisted of parents with cleft children and Group B comprised of parents with at least 2 healthy children who met the inclusion criteria. Dermatoglyphic prints were collected by ink method and evaluated for pattern types, total ridge count and palm prints were evaluated for a-b ridge count, atd angle and asymmetry. Results: Significant difference was observed between Group A and B with reference to pattern types; TRC and a-b ridge count and atd angle. Absence of t point was variably noticed in the mothers of affected children. Conclusion: Dermatoglyphics can be used as tool to study the developmental instability of cleft anomalies and provides data to assess the genetic etiology of clefting. PMID- 30294159 TI - Effect of Laser Etching and Spark Erosion on Retention and Resistance of Partial Veneer Crown Copings Luted with Adhesive Resin Cement. AB - Purpose: There has been less focus on methods to improve the clinical performance of partial veneer crowns. In this study, we wanted to explore the potential of two new surface treatment modalities (laser etching and spark erosion) for improving the longevity of partial veneer crowns. Material and Methods: Conventional partial veneer crown preparation was done on 90 extracted premolars by a single operator. All the samples used in the study were divided into three groups. Group A were samples to be treated by sandblasting alone, Group B were samples to be treated by sandblasting followed by laser etching, and Group C were samples to be treated by sandblasting followed by spark erosion. Each group consisted of two Sub Groups: Sub Group I-Retention test group, Sub Group: II Resistance test group. The prepared teeth were randomly allotted to the three groups and subgroups using lot method. Partial veneer crown copings were fabricated for testing retention and resistance. Castings in each subgroup were luted with resin cement to their respective tooth preparations. Retention and resistance testing of samples were done with the use of an Instron Universal testing machine. Results: The two surface treatments, laser etching and spark erosion (Groups B and C) of metal copings significantly improved the retention and resistance compared to sandblasted surfaces alone (P <= 0.05). Retention and resistance of copings which were sandblasted and spark eroded (Group C) were found to be highest among the three groups (P <= 0.05). Conclusion: Within the limitation of this study, it can be concluded that the combination of spark erosion and sandblasting significantly improves the retention and resistance values of partial veneer crown. This study helps to provide better knowledge about the surface treatment required for success of partial veneer crowns. PMID- 30294161 TI - Association of Stress, Salivary Cortisol, and Chronic Periodontitis: A Clinico biochemical Study. AB - Background: Periodontitis and stress are among the areas of increasing interest over the past two decades. Early detection of these diseases plays a crucial role in successful therapy. Cortisol is a protein which was found to be consistently associated with both. Aim: The present study was aimed to evaluate saliva cortisol levels (SCLs) in chronic periodontitis (CP) patients with and without stress. Materials and Methods: In this cross-sectional study, saliva samples were collected and cortisol levels were determined using ELISA method in 92 participants. The participants were divided into four groups based on periodontal condition (number of teeth present, plaque index (PI), bleeding on probing (BOP), probing pocket depth, and clinical attachment level) and stress levels into Group 1 (no periodontitis and no stress), Group 2 (with periodontitis and no stress), Group 3 (without periodontitis and with stress), and Group 4 (with periodontitis and stress). Results: Overall, 92 adult participants (41 males and 51 females) were included in the study. Participants with stress and periodontitis have high mean SCL when compared to other groups (Group 1: 15.01 +/- 2.62, Group 2: 31.92 +/- 6.80, Group 3: 34.47 +/- 13.47, and Group 4: 60.13 +/- 6.68). Group I shows a significant negative correlation of cortisol to BOP, stress to PI, and stress to cortisol level, whereas there is a positive correlation of SCL to PD in Group 4 which is not statistically significant. Conclusion: SCL showed difference among the groups. SCL were associated with both CP and psychological stress. Increase in inflammation and stress levels enhances the SCL. PMID- 30294162 TI - Unrevealed Caries in Unerupted Teeth: A Prevalence Study. AB - Background: Preeruptive caries are an abnormal, well-circumscribed, radiolucent area, occurring within the coronal dentinal tissue close to the dentinoenamel junction of unerupted teeth. OPGs are commonly taken in children for assessing the dental age and eruption sequence. It can be used as a good diagnostic source for detection of PEIR defects. Aim: The aim of this study is to determine the prevalence of Preeruptive intracoronal dentin radiolucencies in unerupted permanent teeth from orthopantomogram. Settings and Design: A total of 1000 standard orthopantomographs of children below 12 years of age were collected and examined. Methodology: The OPGs were examined for PIER defects in the unerupted teeth. The prevalence of PEIR defects was assessed with respect to age, sex, tooth, and the arch involved. Statistical Analysis: The data obtained were tabulated and analyzed. The prevalence was calculated in percentage. Results: The participant prevalence was 13.6%. The teeth prevalence was 1.20%. The majority (38.9%) of defects were seen in the in the mandibular first premolar. Almost half of the lesions were located on the mesial side (52.3%), with a size less than one third of dentine thickness (53%). Conclusion: PIER defects constitutes an important part of anomalies associated with unerupted teeth and thus needs a proper understanding of its prevalence, etiology, manifestations, and complications. These defects are usually overlooked by clinicians while interpreting radiographs; however, it is of utmost importance to promptly diagnose these defects thus preventing further complications. PMID- 30294163 TI - Candidal Species Identification in Malignant and Potentially Malignant Oral Lesions with Antifungal Resistance Patterns. AB - Objective: Candidal species identification in malignant and potentially malignant oral lesions with antifungal susceptibility. Materials and Methods: Oral candidal carriage, strain diversity, and antifungal susceptibility of Candida were checked for the patients having oral cancer or precancer reporting to the clinics for 11/2 year. Statistically significant patients were selected and a control group was taken. A total of 105 individuals were selected and divided into three different groups. Salivary samples were taken from all the individuals. Candida detection was done using Sabouraud's agar and candidal species detection on CHROMagar. In vitro antifungal sensitivity was done using antifungal disc diffusion method. Results: Candida was isolated from 88.6% of patients with oral cancer and 45.7% in oral precancerous group. C. albicans was the predominant species found in 100% of oral precancerous and 71% in oral cancerous patients. Other Candid a species found were C. tropicalis (9.7%) and C. krusei (19.6%). Antifungal susceptibility showed 4.3% sensitivity to fluconazole and 100% sensitivity to amphotericin B and nystatin. Conclusion: Oral Candida carriage was higher in oral cancerous group and majority of them were sensitive to amphotericin B and nystatin. PMID- 30294164 TI - Dental Caries Experience, Dental Anomalies, and Morphometric Analysis of Canine among Monozygotic and Dizygotic Twins. AB - Background: The study of twins is a well-known and a unique method that is used to investigate the genetic contributions to physical features and diseases in human. Aim: To estimate the relative contributions of genetic and environmental influence to observed variations in different dental features or traits. Methodology: Thirty twins in the age group of 15-30 years were selected for the study, and the dental caries experience scores, dental anomalies, and morphometric analysis of monozygotic (MZ) and dizygotic (DZ) twins were compared. Results: MZ twins unlike DZ twins showed within-pair resemblance in decayed, decayed missing and filled teeth (DMFT), and molar relation. No morphometric analysis parameters and dental anomalies had significant mean difference between the groups. Decay, filling, DMFT, spacing, mandibular irregularity, open bite, and mesiodistal width of the right and left canine showed a higher positive correlation in MZ than DZ twins. Heritability estimate was low for morphometric analysis parameters. There is genetic dominance in decay, DMFT, spacing, molar relation, and diastema. Pearson's correlation revealed a positive and statistically significant correlation among all morphometric analysis parameters for MZ twins, but not DZ twins. Dental caries has a higher concordance rate (87.5%), correlation (71.6%), and heritability (87.8%). Conclusion: Most of the dental parameters are significantly heritable with up to 85% of the variance attributable to genetic factors. Environmental factors play a major role in developing malocclusion and causing dental caries. Morphology of canines can be used as a supplementary tool to determine zygosity. PMID- 30294165 TI - Comparison of Surgical Outcome after Impacted Third Molar Surgery Using Piezotome and a Conventional Rotary Handpiece. AB - Background and Aim: One of the most commonly performed surgical procedures by oral and maxillofacial surgeons all over the world is the removal of impacted teeth. The most critical and important steps in third molar extraction are bone cutting or osteotomy. Many techniques are used for this purpose including chisels and mallet, rotary instruments, and ultrasonic-based bone cutting instruments. Piezotome is newer and innovative device for osteotomy based on piezoelectric vibrations. Piezotome is considered very efficient in performing osteotomy because of its selective cutting; being inert against soft tissues, including nerves and blood vessels. The aim of this study was to compare the surgical outcome of third molar surgery using conventional handpiece and piezotome with all other criteria remaining same for all the individuals. Materials and Methods: All patients reporting to the Department of Oral and Maxillofacial surgery, Manipal College of Dental Sciences, Mangalore, for impacted mandibular third molar removal were screened. A total of 30 patients with same Pederson difficulty index for bilateral impacted third molar were selected for the study. The study involved the use of piezotome on one side (Side A) and rotary technique (Side B) on the other side for osteotomy on the same patient with an interval of 1 month. Therapeutic management was same for both the sides. Operating time was recorded in each surgery. Patients were examined postoperatively on 1st, 3rd, and 7th day and pain, edema, trismus, paresthesia, and dry socket were evaluated and compared on both the sides. Data collected were analyzed statistically. Results: The mean operating time was 48.13 min in piezotome (Side A) and 32.90 min in conventional handpiece (Side B) which was statistically significant (P < 0.001). Furthermore, there was statistically significant difference (P < 0.001) in the level of pain (P < 0.001), number of analgesics taken (P < 0.001), and trismus (P < 0.01) on 1st, 3rd, and 7th days postoperatively. There was no statistically significant difference in edema between the two sides. Paresthesia was present in one patient (3.3%) in Side B, while no paresthesia was present in Side A. No incidence of alveolar osteitis was reported on both the sides. Conclusion: Operating time with piezotome was more than that of conventional handpiece, but the postoperative responses such as pain, trismus, and edema were less in piezotome. Hence, despite being a slower procedure, piezotome can be an effective alternative for osteotomy in impacted third molar surgery. We recommend using piezotome for bone cutting and conventional rotary handpiece for tooth sectioning in order to obtain favorable outcomes as well as decreasing the operating time. PMID- 30294166 TI - Comparative Evaluation of Antimicrobial Efficacy of Platelet-rich Plasma, Platelet-rich Fibrin, and Injectable Platelet-rich Fibrin on the Standard Strains of Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans. AB - Context: Platelet concentrates are commonly used to promote periodontal soft- and hard-tissue regeneration. Recently, their antimicrobial efficacy is also explored. Various platelet concentrates have evolved which differ in the centrifugation protocols. Porphyromonas gingivalis (Pg) and Aggregatibacter actinomycetemcomitans (Aa) have been found to have an important role in periodontal pathology. Aims: In this study, PRP, PRF, and I-PRF are compared for their antibacterial effect against Pg and Aa. Materials and Methods: Blood samples were obtained from ten systemically and periodontally healthy individuals. Platelet concentrates were prepared using standardized centrifugation protocol. Antimicrobial activity was examined on standard strains of Pg and Aa using well diffusion method. Statistical Analysis Used: Means for the width of zones of inhibition were calculated along with standard deviations, and the comparison was made using Wilcoxon signed-rank test. Results: In case of Pg, I-PRF had the widest zone of inhibition which was significantly wider as compared to PRF. Furthermore, PRP had significantly wider zone of inhibition against PRF. In case of Aa, PRP had wider zone of inhibition which was significantly wider as compared to that of PRF and I-PRF. Conclusions: All the three platelet concentrates PRP, PRF, and I-PRF have antibacterial activity, but PRP and I-PRF are more active as compared to PRF. I-PRF being autologous and easy to prepare can be a very useful adjunct to the surgical therapy in bringing down the bacterial count helping in wound healing and regeneration. PMID- 30294167 TI - Comparative Evaluation of Frictional Resistance of Silver-Coated Stainless Steel Wires with Uncoated Stainless Steel Wires: An In vitro Study. AB - Background: Silver is known for its antimicrobial activity. Silver coating effectively reduces Lactobacillus acidophilus and Streptococcus mutans count, thus reducing chances of dental plaque and caries. This silver coating may have effect on frictional property of orthodontic wires. Aim: The aim of this study is to evaluate and compare frictional resistance of silver-coated and uncoated stainless steel (SS) wires. Methods: Forty SS wires were divided into four groups of 10 each: Group 1 - 0.017 * 0.025 inch SS wires (silver coated), Group 2 - 0.017 * 0.025 inch SS wires (control), Group 3 - 0.019 * 0.025 inch SS wires (silver coated), and Group 4 - 0.019 * 0.025 inch SS wires (control). Surface modification of wires was carried out by the thermal vacuum evaporation method with silver (10 nm size) using vacuum-coating unit model. The frictional resistances of all forty wires were checked on forty 0.022 * 0.028 inch slot central incisor brackets (SS wires and brackets from American Orthodontics, St Paul, USA) mounted on metal plates using universal testing machine. Results: There was no significant difference found in frictional resistance between silver coated and uncoated 0.017 * 0.025 inch SS wires group (P = 0.854). Statistically significant reduction in frictional resistance was observed in 0.019 * 0.025 inch coated SS wires in comparison to uncoated wires (P = 0.032). Conclusion: Overall silver coating either did not affect the frictional resistance (0.017 * 0.025 inch SS wires) or reduced it (0.019 * 0.025 inch coated SS wires) compared to uncoated wires. Findings suggest that the use of silver-coated SS wires in routine orthodontic practice can be implemented after further in vivo human clinical trials. PMID- 30294168 TI - Neovascular Pattern in Wound Healing after Zinc Oxide and Curcuma longa Rhizome Extract Dressing Application. AB - Introduction: Zinc oxide-eugenol dressing is widely used in the dentistry field. Eugenol in wound dressing acts as an antibacterial and analgesic agent but known to cause hypersensitivity reaction and allergies. Curcuma longa rhizome extract could perform as a substitute of eugenol as its active compounds have an anti inflammation, antioxidant, anticancer, and antibacterial properties. It has also been shown to have proangiogenic and promote wound healing. This study aimed to discover the number of neovascular in the wound healing process after the application of zinc oxide and C. longa rhizome extract wound dressing. Materials and Methods: Full-thickness excision wound of 6 mm * 6 mm was made in the dorsal of 32 Wistar strains Rattus norvegicus, before being equally divided into eight groups (n = 4): four control groups (C3, C5, C7, and C14) without any dressing and 4 treatment groups (T3, T5, T7, and T14) were dressed with zinc oxide and C. longa extract wound dressing. The rats consecutively sacrificed on day 3 (C3, T3), day 5 (C5, T5), day 7 (C7, T7), and day 14 (C14, T14) to observe the neovascular pattern and number using H and E staining. Obtained data were analyzed using ANOVA. Results: The neovascular growth in both control and treatment groups have the same pattern, while the number of neovascular in treatment groups significantly higher than the control groups (P < 0.05). Conclusions: Wound dressing combination of zinc oxide and C. longa extract can increase the number of neovascular in the wound healing process, while the optimum duration of application is 14 days.

AB - Introduction: To describe the cephalometric characteristic of skeletal Class II malocclusion in Javanese Population at Universitas Airlangga Dental Hospital. Methods: A total of 118 lateral cephalograms of preorthodontic patients with skeletal Class II malocclusion were obtained from Universitas Airlangga Dental Hospital. The lateral cephalograms were analyzed using digital cephalometric analysis to determine the ANB, mandibular length, facial axis, Y-axis, sella to nasion-mandibular plane (SN-MP), and lower anterior facial height (LAFH). Correlation between mandibular length and other variables was analyzed using Pearson correlation test with P < 0.05. Results: There was an increase of ANB, Y axis, SN-MP, and LAFH. While SNB was decrease and mandibular length was shortened. There was a significant correlation between mandibular length and other variables, such as facial axis, SN-MP, LAFH, and ANB. Conclusions: Skeletal Class II malocclusion in Javanese Population at Universitas Airlangga Dental Hospital was characterized by short mandibular length and large ANB mostly not by the increased of SNA but by the lack of SNB. The length of mandible correlated with facial axis angle, lower anterior facial height, and mandibular plane angle.

AB - Background: A fracture of denture base in situ often occurs through a fatigue mechanism, which over a period of time leads to the formation of small cracks, resulting in fracture. Aim and Objective: To evaluate the flexural strength of repaired heat-polymerized acrylic resin, with different percentage of aluminum oxide (Al2O3) added to the repair resin and effect of two different surface treatments on the flexural strength of repaired heat-polymerized acrylic resin and also to evaluate quantification of filler particles using scanning electron microscopy. Materials and Methodology: Fifty specimens of heat-polymerized acrylic resin were prepared according to the American Dental Association specification no. 12 (65 mm * 10 mm * 2.5 mm). Al2O3<50 nm particle size was silanized using metal alloy primer before incorporation in polymer. Two different percentages of Al2O3 nanoparticles, that is, 1% and 1.5% were added to autopolymerizing acrylic resin which was used as repairing material. Results: The study showed that repair resin incorporated with 1.5% Al2O3 in the group surface treated with silicon carbide paper improved the flexural strength of denture base resin. A proper filler distribution and deep penetration within the polymer matrix were observed by scanning electron microscope in the same group.

AB - Aim: This study aimed to determine the correlation between orofacial structure and oropharyngeal airway space. Materials and Methods: It comprised of 160 individuals aged 14-24 years (males: 80 and females: 80), in which digital lateral cephalograms were taken. Linear and cephalometric analyses were performed in all cases. Results: Ba-PNS, apw2-ppw2, hy-apw2, distance between tongue and posterior pharyngeal wall (t-ppw), and Hormion perpendicular and anterior nasal spine-posterior nasal spine (ANS-PNS) showed significant difference between males and females (P < 0.05). Other distances such as Ba-ad1, Ba-ad2, Ptm-ad1, Ptm-ad2, PNS-ppw1, and apw4-ppw4 were statistically nonsignificant (P > 0.05). Conclusion: Linear and cephalometric measurements showed that Ba-PNS, t-ppw, Hy-ppw2, distance between Ho perpendicular and ANS-PNS plane, and apw2-ppw2 were higher in males as compared to females. Lateral cephalograms are useful in orthodontics in performing tracings in individuals with a potential risk of malocclusion.

They may vary in their etiology from numerous infectious and noninfectious causes to a wide array of neoplasms. Accurate diagnosis of such lesions is vital for their prompt and precise management. Rhinoscleroma (RS), as its name suggests, is a persistent, specific, granulomatous disease that results in sclerosis of the affected organ - most frequently the nose. Although its occurrence in the adjacent sites has been reported, the clinical findings did not offer much deviation from the expected. Reported here is a case of RS involving the palate which not only detoured from its usual site and course of spread but also gave off a confusing facade in terms of its clinical presentation. PMID- 30294175 TI - The Efficacy of Low-Level Laser Therapy in Treating Oral Papilloma: A Case Reporting A Lingual Location. AB - Oral papilloma is a benign proliferation of the stratified epithelium, which results in a papillary or verrucous exophytic mass, which can be induced by human papillomavirus. These oral mucosa lesions are most often asymptomatic and have small progression. Laser-assisted surgery is common nowadays with several advantages including successful hemostasis, devoid of sutures, wound sterilization and minimal postoperative pain, and edema. The aim of this report is to present the oral papilloma in a 40-year-old female patient and its treatment with soft-tissue laser. The lesion was excised with diode laser, and the healing was uneventful in a follow-up visit after 1 month. Oral papillomas can be found in young adult patient's oral cavity, and laser dentistry can be used by dental clinicians to treat these kinds of oral lesions and should be considered as an alternative to conventional surgery.

AB - Pathologic tooth migration is a change in tooth position resulting from disruption of the forces that maintain teeth in a normal position in relation to their arch. The disruption of the equilibrium in tooth position may be caused by various etiologic factors. Loss of attachment apparatus along with a non periodontal related condition such as excess occlusal force, a progressive migration of tooth may take place. Mostly this migration can be associated with aesthetic damage of the smile line. To solve these issues, a combination of periodontal and orthodontic treatment is often needed. In this presentation a 23 year-old, systemically healthy, non-smoking female presented with the complaint of bleeding gums, mobility and increased space between upper and lower front teeth causing un-aesthetic appearance and low self esteem. She was treated with interdisciplinary approach of orthodontic and periodontal intervention. Improvement of facial esthetics contributed to the self-confidence of an adult periodontal patient with pathologic tooth migration. Follow up at 10 years post treatment confirmed the good choice of treatment planning and the tendency to improve the results over time. Periodontally compromised orthodontic patients can be satisfactorily treated, achieving correction of the malocclusion and a marked improvement in esthetics when an interdisciplinary approach is used. PMID- 30294178 TI - Surgical Management of Hyperdivergent Class II Malocclusion with Vertical Maxillary Excess: A 2-year Follow-up. AB - Skeletal Class II malocclusions with vertical maxillary excess (VME) present with an amalgamation of several problems pertaining to psychological, esthetics, and function. The optimal treatment plan in such cases includes a synchronized orthodontic-surgical approach through superior repositioning and setback of maxilla by means of Le Fort I osteotomy and augmentation genioplasty. This case report describes a multidisciplinary approach in the successful management of a patient with VME to achieve superior esthetics and function. PMID- 30294179 TI - Surgical Management of Complex Odontoma Associated with Agenesis of a Molar. AB - Odontomas are mixed odontogenic tumors composed of mineralized tissue of ectomesenchymal origin. These are usually detected in routine radiographs and may have a variable etiology such as local trauma, genetic mutation, or infection. They are classified into two main types: complex and compound. Complex odontomas are rare and they rarely erupt into the oral cavity as they lack periodontal ligament. This is the report of one such case of complex odontoma where an 11 year-old girl reported with an asymptomatic swelling, in relation to the left angle of the mandible. The case report highlights the clinical and radiographic findings, investigations done to arrive at the diagnosis and the treatment rendered. This report is of clinical importance because of its rare association with the agenesis of a molar tooth. PMID- 30294180 TI - The Metabolic Syndrome and Menopause. PMID- 30294181 TI - Analyzing Thyroid Dysfunction in the Climacteric. AB - Introduction: Perimenopause and menopause is an integral part of every woman's life constituting about 30% of the Indian female population. Hypothyroidism is a condition that can mimic menopausal symptoms very often. Therefore, routine screening of thyroid function in the climacteric and menopausal period to determine subclinical thyroid disease can be recommended. Materials and Methods: With this background, we conducted a prospective study in our institute, North Eastern Indira Gandhi Regional Institute of Health and Medical Sciences, to evaluate the abnormal thyroid function tests in perimenopausal and postmenopausal women aged 40-80 years. Results and Observations: Subclinical hypothyroidism status increases from the age group of 40-70 years and hypothyroidism increases in slow frequency from 40 to 70 years after that there is plateauing. Interestingly, the frequency of hyperthyroidism remains same in all the age groups. Conclusion: Looking at the increased risks of thyroid disorders with age, screening of thyroid disorders can be started at the age of 40 years with estimation of serum levels of TSH. This gives us the opportunity to treat both subclinical and clinical hypothyroidism and hyperthyroidism women. PMID- 30294182 TI - Prevalence of Osteoporosis in Peri- and Post-menopausal Women in Slum Area of Mumbai, India. AB - Objective: We conducted our study involving 1400 peri- and post-menopausal women who live in a slum area of Mumbai to determine the prevalence of osteoporosis, awareness about osteoporosis, education (knowledge regarding osteoporosis), treatment and prevention of osteoporosis. Material and Methods: A detailed medical, surgical, obstetrical & gynecological, menstrual, and drug history was recorded in a predesigned questionnaire designated for the study. Height and weight and body mass index were measured, physical activity level especially load bearing exercise was recorded, and amount of sunlight exposure per day was also recorded. Food intake was estimated using the 24 h dietary recall method and calcium and Vitamin D consumption pattern was assessed. We used calcaneum quantitative ultrasound to assess bone mineral density (BMD) for such large population. Results: The prevalence of low BMD was found in more than half of this population (81%). The mean age in Group I was found to be 36.50 +/- 2.74 years as compared to 37.5 +/- 3.44 years in Group II with low BMD, which was statistically significant (P = 0.02). The average age at menopause was 51.62 +/- 5.72 years in Group I and 49.43 +/- 4.52 years in Group II. The number of children and type of menopause has been found to be associated with low BMD in our study. Lack of physical exercise and low-calcium diet were significantly associated with low BMD. Conclusion: Our study showed that there is a high prevalence of Vitamin D deficiency and Osteoporosis even in adult women who live in a slum area. The findings from the study also suggest the need for large community-based studies so that high-risk population can be picked up early and early interventions and other lifestyle changes can be instituted so that no delay in implementing state and national or international health policy to tackle this increasing global health problem. The public awareness is important, and strategies to identify and manage low BMD in the primary care setting needs to be established and implemented. PMID- 30294183 TI - Evaluation of Cardiovascular Risk in Climacteric Women: A Cross-Sectional Study. AB - Purpose: To identify cardiovascular risk factors in women between 40 and 65 years old in two private clinic of gynecology in Minas Gerais. Methods: Cross-sectional study from January/2016 to January/2017 in 137 climacteric women. A standardized questionnaire was used to evaluate socio-demographic characteristics, climacteric phases, cardiovascular risk factors, menopause (age, time and type), number of pregnancies, normal births, abortions, partners and hormonal therapy. The evaluation model was used according to the Framingham risk score. Results: The median age was 47 years, and 35% were postmenopausal. The majority were married and 42.3% caucasian. Abdominal circumference greater than 80 cm was observed in 87.6%, and greater than 88 cm in 67.2%. High total cholesterol (TC) was observed in 48.2%. Low levels of high-density lipoprotein (HDL-c) were observed in 42.3%. Elevated levels were observed for low density lipoprotein (LDL-c) in 39.4%, triglycerides in 29.9%, and fasting glucose in 8.8%. Also, systolic and diastolic blood pressure were considered high in 25.5% cases. Postmenopausal women presented higher values of TC and HDL-c. Analysis of the Framingham risk score revealed a higher cardiovascular risk for postmenopausal women. Higher values of waist circumference, glycemia and triglycerides were observed for women with higher cardiovascular risk. Conclusions: Postmenopausal women had a higher risk of cardiovascular events when compared to premenopausal ones. PMID- 30294184 TI - Study on Prevalence and Severity of Urogenital Complaints in Postmenopausal Women at a Tertiary Care Hospital. AB - Objective: The objective of this study was (1) to find the prevalence of urogenital (UG) complaints after menopause, (2) to evaluate the various risk factors for UG problems in postmenopausal women, and (3) to assess the severity of the symptoms depending on the duration of menopause. Materials and Methods: This study is a prospective study conducted at the Specialty Outpatient Department in Safdarjung Hospital over a period of 1 year. Two hundred postmenopausal women during this period were screened for UG complaints by eliciting detailed history in a pro forma and were divided into two groups based on the duration of menopause. Women with preexisting complaints before menopause and those with some medical disorders such as diabetes, stroke, or neurological problems were excluded from the study. Data were analyzed by standard statistical analytical tests. Results: The prevalence of UG symptoms in our study was 67%. Group A constitutes 127 (63.5%) participants in which menopause attained was of 1 5-year duration. Group B comprises the women with >5-year duration of menopause and it includes 73 (36.5%) patients. Among the genital complaints, vaginal dryness was the most common complaint in both the groups (Group A: 62% and Group B: 48%) followed by vaginal discharge or infection (Group A: 28% and Group B: 25%). Around 19 (15%) in Group A and 10 (13.6%) in Group B were having burning micturition (dysuria), the most common complaint encountered. The UG complaints were not statistically significantly different in both the groups. The severity of the symptoms was significantly different in two groups with more severe complaints in Group A as compared to Group B. Conclusion: UG complaints associated with estrogen loss can occur episodically throughout a women's life, but it is most common and chronic in the duration in postmenopausal women. PMID- 30294185 TI - A Prospective, Randomized, Open-Label Study Comparing the Efficacy and Safety of Clonazepam versus Nortriptyline on Quality of Life in 40+ Years old Women Presenting with Restless Leg Syndrome. AB - Introduction: Restless legs syndrome (RLS) is a neurological disorder characterized by an urge to move the legs usually accompanied by unpleasant leg sensations. RLS also impacts health related quality of life (QOL) in patients suffering from it. Further, it affects women more than men. Although a voluminous literature of studies is available evaluating the role of benzodiazepines (clonazepam and antidepressant (nortriptyline) in the treatment of RLS, but to the best of our knowledge, no comparative study is available comparing both of these drugs for efficacy and safety for the treatment of RLS QoL among 40 + years old women. Materials and Methods: A prospective, randomized, open label comparative study was conducted in Postgraduate Department of Pharmacology in collaboration with the Department of General Medicine, Government Medical College, Jammu, a tertiary care teaching hospital for 1 year. Conclusion: Clonazepam proved to be significantly better in improving RLSQoL score. Difference between respective baselines of both groups was statistically insignificant. PMID- 30294186 TI - Diagnostic Utility of Endometrial Aspiration Cytology in Women with Abnormal Uterine Bleeding. AB - Context: Abnormal uterine bleeding (AUB) is a common problem for which women seek gynecological consultation. Endometrial aspiration cytology (EAC) has emerged as a minimally invasive and cost-effective diagnostic procedure for screening the endometrial status of these patients that can aid in diagnosis in high-burden and resource-limited settings. Aims: The study was conducted to evaluate the utility of EAC in women with AUB, and the cytological diagnosis was compared with the histopathology. Materials and Methods: A total of 100 patients presenting with AUB were subjected to EAC using a 4-mm Karman's cannula. Later, they also underwent endometrial dilation and curettage. The cytology smears were evaluated for architectural and cytomorphological features. The cytological diagnoses henceforth made were compared with the histopathological diagnosis to calculate sensitivity, specificity, and diagnostic accuracy of EAC. Results: EAC showed a sample adequacy of 89% viz a viz 90% for histopathology. EAC showed a sensitivity of 87.5% and 100% for diagnosing benign and malignant conditions, respectively. There was a good overall agreement between cytological and histopathological diagnosis (kappa = 0.585). Conclusions: EAC is an effective and minimally invasive procedure for the primary investigation of women with AUB. PMID- 30294187 TI - Knowledge and Attitude of Adolescent Girls and Their Mothers Regarding Cervical Cancer: A Community-Based Cross-Sectional Study. AB - Background: Cervical cancer is the second most commonly diagnosed cancer in India. The mother's awareness about the symptoms and risk factors has a large impact on the daughter's knowledge and attitude. Mother and adolescent daughter duos were selected as the sample as they are the target population at risk for suffering from carcinoma cervix. Mothers are the prime information providers and in an excellent position to aware their adolescent daughters about cervical cancer. Objectives: The aim of this study is to determine knowledge and attitude of adolescent girls and their mothers regarding cervical cancer and to find the association between the education of the mothers and their knowledge about risk factors. Materials and Methods: A community-based cross-sectional study was conducted among 100 duos of adolescent daughters along with their mothers residing in Balmiki Basti (Delhi), using a predesigned, pretested, semi structured interview schedule. The collected data were analyzed using SPSS-22 version. Results: Only 61% of mothers and 52% of daughters have heard about cervical cancer. Inter-menstrual bleeding was the most common symptom recognized by the mother (50%) and daughter (44%) duos followed by postmenopausal bleeding (47% of mothers and 33% of daughters). Most common risk factors recognized by mothers and their daughters were promiscuity and tobacco and smoking. About 81% of mothers and 68% of daughters have a positive attitude toward internal examination by a gynecologist at least once in 3 years. Human papillomavirus infection was recognized as a risk factor by 13 among which 8 were educated till graduation (P < 0.05). Conclusions: Study revealed a low-level knowledge about cervical cancer among adolescent daughters and their mothers. Therefore, there is an urgent need to empower the women by educating them on this issue. Furthermore, there is a need to encourage the mothers to communicate the right information to their adolescent daughters. PMID- 30294188 TI - An Overview of Menopausal Symptoms Using the Menopause Rating Scale in a Tertiary Care Center. AB - Context: Due to increased life expectancy worldwide, women are expected to spend a significant portion of their lives in menopause. Proven prevention strategies against serious risks and tested effective treatments for common symptoms may remain unutilized in our population if these women are not asked about these symptoms. Aim: This study aims to assess the prevalence of different menopausal symptoms and their severity according to menopause rating scale (MRS) in women. Setting and Design: The present study was a cross-sectional survey, conducted in the outpatient department of gynecology and obstetrics. Subjects and Methods: After written and informed consent, 121 women having their last menstrual period at least 1 year ago were included. The menopausal symptoms were assessed using the MRS. The primary outcome measure in this study was the prevalence of menopausal symptoms in these women according to MRS and the severity of these symptoms. Statistical Analysis Used: Data were analyzed using the SPSS software program, version 15.0 (IBM, Armonk, New York, USA). Results: The most common symptom was mental and physical exhaustion which was reported by 88 (72%) women, followed by joint and muscular discomfort which was reported by 83 (68.59%). Hot flushes were reported by 54 (44.62%) respondents. Majority of women reported mild to-moderate symptoms. Conclusions: The prevalence of menopausal symptoms is high, and a health policy needs to be generated for the region. PMID- 30294189 TI - Patterns of Age- and Sex-Related Variations in Bone Mineral Density of Lumbar Spine and Total Femur: A Retrospective Diagnostic Laboratory-Based Study. AB - Background: Osteoporosis is a major public health problem and should be a priority for healthcare providers and policymakers as it is an important reason of morbidity, mortality, and high-cost incurred in the management of its complications such as hip fractures. This study is designed to assess the bone mineral density (BMD) variation with age, site, and sex. Study is based on diagnostic laboratory data of BMD. Methods: A retrospective analysis was conducted on a sample population of 935 persons (73.5% women, 26.4% men), who underwent dual-energy X-ray absorptiometry scan between 2015 and 2017 in a National Accreditation Board for Testing and Calibration Laboratories accredited Mumbai (Maharashtra, India) based diagnostic laboratory. Lumbar spine, right and left total femur, BMD were analyzed across age, sex, and sites. The prevalence of low BMD and osteoporosis at these sites has been estimated as per the World Health Organization criteria of osteoporosis diagnosis using T scores. Results: Overall the prevalence of osteoporosis was found to be 6.4%, 5.5%, and 16.4%, while the prevalence of low BMD was 32.6%, 32.8%, and 31.2% at right total femur, left total femur, and lumbar spine, respectively. The decline in BMD at lumbar spine is more among women and it was a consistent decline with age, while among men' decline rate was less at all three sites. Conclusion: Our study highlighted the variation of BMD at different sites of body and higher vulnerability of spine for fragility fractures. Our study has shown a sharp decline in BMD among women during transition from 5th to 6th decade which signifies association of menopause with osteoporosis. Major limitation of the study is unavailability of clinical profiles of the subjects because of which it is difficult to ascertain whether BMD estimation was a diagnostic or screening procedure. In addition, study is conducted in diagnostic lab settings, due to which it is possible to overestimate prevalence of low BMD and osteoporosis by extrapolating these findings to the community. PMID- 30294190 TI - Retained Fetal Bones: An Unusual Cause of Granulomatous Reaction on Papanicolaou Smear. AB - Granulomas are a rare finding on Papanicolaou (Pap) smear which if encountered are usually attributed to tuberculosis, especially in an endemic country like India. Here, we report an interesting case of a 40-year-old female presenting with blood-stained discharge and chronic pelvic pain for 8 years. She was advised Pap smear which showed granulomatous inflammation suggestive of tuberculosis. The patient was worked up for tuberculosis which was noncontributory. Dilatation and curettage was done which revealed multiple small bones and bony chips in the endometrial cavity. Following the removal of bones, the patient showed considerable symptomatic improvement. Repeat Pap smear did not reveal any evidence of granuloma. Even after extensive search of literature, we did not come across any such case report in which intrauterine retention of fetal bones evoked a granulomatous response in cervical smears though the presence of uterine granulomas in response to foreign body has been well documented. PMID- 30294191 TI - Low-Grade Endometrial Stromal Sarcoma in a Postmenopausal Woman with Third-Degree Uterovaginal Prolapse: A Rare Case with Review of the Literature. AB - Endometrial stromal sarcomas (ESSs) are rare malignant tumors of the uterus that arise from the endometrial stroma, the annual incidence of ESS being 1-2/million women. Patients present with nonspecific complaints of abnormal uterine bleeding, pelvic pain, and pressure symptoms. Postmenopausal women rarely present with a low-grade ESS, as it is more common in younger women. ESS is usually confused with leiomyomas radiologically. Histopathological examination and immunohistochemistry are essential for the diagnosis. We, herein, report a case of a postmenopausal female who presented with something coming out per vagina. The clinical impression was that of a third-degree uterovaginal prolapse that on histopathological examination was diagnosed as a low-grade ESS. PMID- 30294192 TI - Asymptotic Behavior of Cox's Partial Likelihood and its Application to Variable Selection. AB - For theoretical properties of variable selection procedures for Cox's model, we study the asymptotic behavior of partial likelihood for the Cox model. We find that the partial likelihood does not behave like an ordinary likelihood, whose sample average typically tends to its expected value, a finite number, in probability. Under some mild conditions, we prove that the sample average of partial likelihood tends to infinity at the rate of the logarithm of the sample size, in probability. We apply the asymptotic results on the partial likelihood to study tuning parameter selection for penalized partial likelihood. We find that the penalized partial likelihood with the generalized cross-validation (GCV) tuning parameter proposed in Fan and Li (2002) enjoys the model selection consistency property, despite the fact that GCV, AIC and Cp , equivalent in the context of linear regression models, are not model selection consistent. Our empirical studies via Monte Carlo simulation and a data example confirm our theoretical findings. PMID- 30294193 TI - Activity evaluation of some psychoactive drugs with the application of QSAR/QSPR modeling methods. AB - A set of psychoactive drugs has been analyzed with the use of quantitative structure-activity/property relationships methods. The purpose of this study was to demonstrate both the common and differentiating characteristics of the above mentioned chemical compounds, physicochemical as well as pharmacological based on the quantum chemical calculations and selected biological activity data and chromatographic retention parameters. During the study, the ab initio model of molecular modeling was performed and PCA, FA, and MLR as the types of chemometric approach. QSAR/QSPR models were proposed based on chosen statistically significant descriptors. The relationship between the structure and biological activity data was able to class and describe the psychoactive properties of the molecules studied. The applied chemometric approaches revealed the influential features of tested structures responsible for their pharmacological activity together with some additional physicochemical properties.

PMID- 30294195 TI - Cost Effectiveness of Strategies for Recruiting Low-Income Families for Behavioral Parent Training. AB - The goal of this study was to assess cost, effectiveness, and cost-effectiveness of recruitment strategies used to engage low-income families of young children with disruptive behavior disorder to participate in a Behavioral Parent Training (BPT) program. For this analysis, we used data on labor and non-labor resources associated with 13 recruitment strategies implemented in February 2014 through February 2016. We assessed the effectiveness of each strategy as the number of families that enrolled into the study. Cost-effectiveness of each recruitment strategy was expressed as cost per family enrolled; analysis was conducted in 2016. We calculated the cost of total recruitment effort for 13 strategies during the 2-year period to be $11,496 with an average cost of $885 per recruitment strategy or $255 per enrolled family. Across strategies, total costs ranged from $25 to $2,540. "University mass e-mail" and "school flyers" resulted in the most phone screens (34 each); however, only 10% of these families enrolled in the study (3 and 4 families, respectively). "Craigslist" was the most effective strategy with 30 families screened and 11 of them enrolling. Three strategies did not yield any participants. The four strategies with the lowest cost per family enrolled were "Facebook page," "Craigslist," "university mass e-mail," and "organization/agency" (< $90). In conclusion, we found that some recruitment strategies were more successful at engaging low-income families to participate in a BPT program than others. Our results indicate that using a combination of recruitment strategies may be the optimal approach for recruiting low-income families. PMID- 30294196 TI - Change in Maternal Stress for Families in Treatment for their Children with Oppositional Defiant Disorder. AB - Our objective was to predict change in maternal stress over the course of a randomized clinical trial comparing the efficacy of two interventions for Oppositional Defiant Disorder (ODD): Parent Management Training and Collaborative & Proactive Solutions. In a secondary analysis of data collected from this randomized clinical trial, we examined whether children's self-reported positive relations with their parents impacted responsiveness to treatment, which in turn impacted maternal stress. One hundred thirty-four children and their parents (38.1% female, ages 7-14, M age = 9.51, SD = 1.77) were tracked across three time points: pre-treatment; one-week post-treatment; and six-month post-treatment. Hierarchical linear models tested change in children's reports of positive relations with parents, clinician reports of ODD severity, and maternal reports of parenting stress. Models then tested multilevel mediation from positive relations with parents, through ODD severity, onto maternal stress. Hypothesized indirect effects were supported such that children's reports of positive views toward parents uniquely predicted reductions in ODD severity over time, which in turn uniquely predicted reductions in maternal stress. Results highlight the promise of potential secondary benefits for parents following interventions for children with oppositional problems. Furthermore, results underscore the importance of the parent-child relationship as both a protective factor and as an additional target to complement interventions for child disruptive behaviors. PMID- 30294197 TI - When the Alpha is the Omega: P-Values, "Substantial Evidence," and the 0.05 Standard at FDA. AB - A prominent feature of statistical reasoning for nearly a century, the p-value plays an especially vital role in the clinical testing of new drugs. Over the last fifty years, the U.S. Food and Drug Administration (FDA) has relied on p values and significance testing to demonstrate the efficacy of new drugs in the premarket approval process. This article seeks to illuminate the history of this statistic and explain how the statistical significance threshold of 0.05, commonly decried as an arbitrary cutoff, is a useful tool that came to be the cornerstone of FDA decision-making. PMID- 30294198 TI - Sarcoidosis-associated Pulmonary Hypertension: Pathophysiology, Diagnosis, and Treatment. AB - Clinicians in pulmonary medicine frequently confront the challenge of screening, diagnosis and management of pulmonary hypertension (PH) in sarcoidosis patients who present with unexplained dyspnea. Sarcoidosis associated pulmonary hypertension (SAPH) is most prevalent in patients with pulmonary fibrosis, though it can be independent of airflow obstruction or restriction. SAPH independently associates with significantly increased mortality and decreased functional capacity, outcomes which can be mitigated by early detection and focused treatment. In this review, we discuss the pathophysiology of SAPH, which may resemble pulmonary arterial hypertension as well as secondary causes of PH. We offer a screening algorithm for SAPH, and advocate for detailed assessment of the cause of PH in each patient prior to choice of an individualized treatment plan. We note that treatment of sarcoidosis via immune suppression is typically insufficient to adequately treat SAPH. We discuss secondary causes of SAPH such as left heart disease, sleep disordered breathing, and thromboembolic disease, and the evidence for use of PH-specific therapy in select cases of SAPH. Management of SAPH by clinicians experienced in PH, with early referral to transplantation in refractory cases is advised. PMID- 30294199 TI - Field Investigation of Ambulatory Clinic Exam Room Design with respect to Computing Devices: A Pilot Study. AB - The Department of Veterans Affairs (VA) has developed a new exam room design standard that is intended to facilitate a greater degree of patient centeredness. This new design includes a wall-mounted monitor on an armature system and a moveable table workspace. To date, however, this design has not been formally evaluated in a field setting. We conducted observations and interviews with primary care providers and their patients from three locations within the Phoenix VA Health Care System, in a pilot study comparing the new exam room design standard with the older legacy exam rooms. When using the new exam room layout, providers spent a greater proportion of time focused on the patient, spent more time in screen-sharing activities with the patient, and had a higher degree of self-reported situation awareness. However, the legacy exam rooms were perceived as better facilitating workflow integration. Provider and patient debrief interviews were supportive of the new exam room design. Overall, our field study results suggest that the new exam room design does contribute to a greater degree of patient centeredness, though more thorough evaluations are required to support these preliminary results. PMID- 30294200 TI - Adversity and children experiencing family homelessness: Implications for health. AB - This study tests links between adversity and health problems among children in family emergency housing. Children who experience family homelessness are at risk to also experience high levels of stress, health problems, and need for pediatric care. Understanding the connection between stress and health holds the potential to reduce persistent health disparities. Analyses tested whether experiencing a greater number of stressful life events during the early years of life was related to worse health conditions, emergency health care utilization, and hospitalizations. Parents noted children's experience of negative stressful life events, health problems, emergency room (ER) use, and hospitalization. Two cohorts of kindergarten-aged children staying in emergency family housing participated in the study in 2006-07 (n = 104) and in 2008-09 (n = 138), with the results examined separately. In both cohorts, more health problems were acknowledged for children exposed to more negative stressful life events. Stressful life events were not related to ER use but did relate to hospitalization for the 2006-07 cohort. Results affirm links between stress in early childhood and health problems among children living in emergency housing. Findings are consistent with the hypothesis that adversity in early childhood contributes to income and racial disparities in health. PMID- 30294201 TI - Bilberry extract and anthocyanins suppress unfolded protein response induced by exposure to blue LED light of cells in photoreceptor cell line. AB - Purpose: The purpose of this study was to investigate the effects of bilberry extract with its anthocyanins on retinal photoreceptor cell damage and on the endoplasmic reticulum (ER) stress induced by exposure to blue light-emitting diode (LED) light. Methods: Cultured murine photoreceptor cells (661W) were exposed to blue LED light with or without bilberry extract or its anthocyanins in the culture media. Aggregated short-wavelength opsin (S-opsin) in murine photoreceptor cells was observed with immunostaining. The expression of factors involved in the unfolded protein response was examined with immunoblot analysis and quantitative real-time reverse transcription (RT)-PCR. Furthermore, cell death was observed with double staining with Hoechst 33342 and propidium iodide after dithiothreitol (DTT) treatment. Results: Bilberry extract and anthocyanins suppressed the aggregation of S-opsin, activation of ATF4, and expression of the mRNA of the factors associated with the unfolded protein response (UPR). In addition, bilberry extract and the anthocyanins inhibited the death of photoreceptor cells induced by DTT, an ER stress inducer. Conclusions: These findings suggest that bilberry extract containing anthocyanins can alter the effects of blue LED light and DTT-induced retinal photoreceptor cell damage. These effects were achieved by modulating the activation of ATF4 and through the suppression of the abnormal aggregation of S-opsin. PMID- 30294203 TI - DETENTION OUTLET RETROFIT IMPROVES THE FUNCTIONALITY OF EXISTING DETENTION BASINS BY REDUCING EROSIVE FLOWS IN RECEIVING CHANNELS. AB - By discharging excess stormwater at rates that more frequently exceed the critical flow for stream erosion, conventional detention basins often contribute to increased channel instability in urban and suburban systems that can be detrimental to aquatic habitat and water quality, as well as adjacent property and infrastructure. However, these ubiquitous assets, valued at approximately $600,000 per km2 in a representative suburban watershed, are ideal candidates to aid in reversing such cycles of channel degradation because improving their functionality would not necessarily require property acquisition or heavy construction. The objective of this research was to develop a simple, cost effective device that could be installed in detention basin outlets to reduce the erosive power of the relatively frequent storm events (~ < two-year recurrence) and provide a passive bypass to maintain flood control performance during infrequent storms (such as the 100-year recurrence). Results from a pilot installation show that the Detain H2O device reduced the cumulative sediment transport capacity of the preretrofit condition by greater than 40%, and contributed to reduced flashiness and prolonged baseflows in receiving streams. When scaling the strategy across a watershed, these results suggest that potential gains in water quality and stream channel stability could be achieved at costs that are orders of magnitude less than comparable benefits from newly constructed stormwater control measures. PMID- 30294202 TI - Effects of aging and environmental tobacco smoke exposure on ocular and plasma circulatory microRNAs in the Rhesus macaque. AB - Purpose: To identify changes induced by environmental tobacco smoke (ETS) in circulatory microRNA (miRNA) in plasma and ocular fluids of the Rhesus macaque and compare these changes to normal age-related changes. Tobacco smoke has been identified as the leading environmental risk factor for age-related macular degeneration (AMD). Methods: All Rhesus macaques were housed at the California National Primate Research Center (CNPRC), University of California, Davis. Four groups of animals were used: Group 1 (1-3 years old), Group 2 (19-28 years old), Group 3 (10-16 years old), and Group 4 (middle aged, 9-14 years old). Group 4 was exposed to smoke for 1 month. Ocular fluids and plasma samples were collected, miRNAs isolated, and expression data obtained using Affymetrix miRNA GeneTitan Array Plates 4.0. Bioinformatics analysis was done on the Affymetrix Expression Console (EC), Transcriptome Analysis Software (TAS) using ANOVA for candidate miRNA selection, followed by Ingenuity Pathway Analysis (IPA). Results: The expression of circulatory miRNAs showed statistically significant changes with age and ETS. In the plasma samples, 45 miRNAs were strongly upregulated (fold change >+/-1.5, p<0.05) upon ETS exposure. In the vitreous, three miRNAs were statistically significantly downregulated with ETS, and two of them (miR-6794 and miR-6790) were also statistically significantly downregulated with age. Some retinal layers exhibited a thinning trend measured with optical coherence tomography (OCT) imaging. The pathways activated were IL-17A, VEGF, and recruitment of eosinophils, Th2 lymphocytes, and macrophages. Conclusions: ETS exposure of Rhesus macaques resulted in statistically significant changes in the expression of the circulatory miRNAs, distinct from those affected by aging. The pathways activated appear to be common for ETS and AMD pathogenesis. These data will be used to develop an animal model of early dry AMD.

The study aims to investigate the relation of serum IGF-1 levels with cognitive impairment and fatigue in MS patients. Methods: This study was conducted on 46 MS patients and 46 healthy controls. All participants were subjected to clinical assessment, serum IGF-1 levels, expanded disability status scale (EDSS), modified fatigue impact scale (MFIS), and Montreal cognitive assessment (MoCA) scale. Results: There was no significant difference between patients and controls regarding serum IGF-1 levels (P = 0.19). However, low serum levels of IGF-1 have significantly greater odds for fatigue (P = 0.002) and cognitive impairment (P < 0.001). Also, serum IGF-1 levels have a significant negative correlation with MFIS (r = - 0.701 and P < 0.001) and a significant positive correlation with MoCA scale (r = + 0.84 and P < 0.001). Conclusions: The results, specifically that low levels of serum IGF-1 was associated with cognitive impairment and fatigue in MS, suggest that IGF-I may be involved in the pathogenesis of cognitive deficits and fatigue in MS disease.

PMID- 30294205 TI - The relationship between the severity of disability and serum IL-8 in acute ischemic stroke patients. AB - Background: Stroke is the third leading cause of death and leading cause of adult disability worldwide. Long-term disability is a significant problem among survivors; post-stroke inflammation is well known to contribute to the expansion of the ischemic lesion resulting in significant morbidity and disability. To study the impact of serum level of IL-8 on severity of disability in patients with acute ischemic stroke in the first 48 h post stroke. Methods: A cross sectional case control study was conducted on 44 patients with acute ischemic stroke (in the first 48 h). The patients were subjected to full neurological examination, computed tomography (CT) and magnetic resonance imaging (MRI) of the brain, and assessment of stroke disability using the National Institute of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS). Measurement of the serum levels of IL-8, erythrocyte sedimentation rate, and C-reactive protein (CRP) was done. Forty-four matched control subjects for their age and sex were included for comparison of serum level of IL-8. Results: The level of IL-8 was significantly higher in the patients than in the control subjects (p < 0.001).There was a statistically significant positive correlation between serum level of IL-8 and disability assessed by NIHSS (r = 0.42, p = 0.004). The patients with moderate disability showed significant higher IL-8 levels than those with minor disability (p = 0.02). Conclusion: The severity of disability in early acute ischemic stroke is highly correlated to the serum level of IL-8.

PMID- 30294208 TI - Evaluation of the population dynamics of microalgae isolated from the state of Chiapas, Mexico with respect to the nutritional quality of water. AB - As Chiapas state, Mexico, counts on an extensive hydrography with diverse nutrimental and climatic characteristics, it therefore allows isolating and identifying microalgae with bioenergetics potential. For this purpose, samples from 8 locations were collected, corresponding to 6 rivers, a wastewater and a springwater. The isolation of microalgae was developed for 4 weeks with 12:12 light/dark cycles. We demonstrated that the most efficient means for the isolation of microalgae of the hydrographic areas evaluated was the medium BG11 with 80.53% effectiveness. Of the microalgal consortium identified, 90% are composed of microalgae belonging to the class Chlorophycear. It was shown that another factor favouring the richness of morphotypes identified in the Santo Domingo River is associated with adequate concentrations of macroelements such as nitrates, nitrites, ammonium, phosphorus, sodium, potassium, magnesium and calcium at concentrations of 0.03 mg/l, 0.0006 mg/l, 0.08 mg/l, 0.03 mg/l, 62.93 mg/l, 5.46 mg/l, 34.52 mg/l and 48.78 mg/l respectively and microelements such as copper, zinc, iron, andmanganese at concentrations less than 0.2 mg/l in all microelements. The identified morphotypes, according to literature, have lipid contents ranging from 2 to 90%; this is of biotechnological importance for the production of biodiesel.

PMID- 30294211 TI - Growth dynamics of Dracaena cinnabari under controlled conditions as the most effective way to protect endangered species. AB - Dracaena cinnabari Balf. fil. is an endangered endemic species growing on the Yemeni island of Soqotra. Dracaena woodlands are considered as one of the oldest forest communities on Earth. Uncontrolled grazing unfortunately caused a lack of naturally occurring regeneration. Our two-year research was focused on the growth dynamics of Dracaena seedlings from two separate populations. One hundred of germinated seeds from two different altitudes from the island were sown and planted under the same conditions. Average increment and difference between the growth dynamics of plants from the two localities were investigated. The observed data on this plant species revealed very interesting, hitherto unknown results. (1) The seedlings germinated within a time period from four to ten weeks. Germination rate was 90% on the Firmihin highland plateau and 78% on the Scand Mountain. (2) Average plant length from both localities was almost the same (24.9 cm) at the end of measurement. Differences in values between the two populations proved as non-significant. (3) A significant difference was found in the number of leaves and in the sum of lengths of all leaves on one plant. While the seedlings from Firmihin featured a wide spreading above-ground part with a large number of leaves, the plants from Scand invested more energy into faster leaves elongation rate. (4) Growth dynamics reflected seasonal changes. Increments were slower or ceased during the period of vegetative rest from autumn to spring. (5) Average mortality rate was 13%. Most of the plants died during the period of vegetative rest. Further study on germination and regeneration under artificial conditions seems like the only way to prevent species extinction.

AB - We report morphometric data for 133 specimens of Diplometopon zarudnyi (Squamata: Trogonophidae) collected across its range within Riyadh province of Saudi Arabia. One-way analyses of variance revealed that differences exist in most characters. Snout-vent length and vent-tail length showed slight and inconsistent differences among samples. D. zarudnyi is characterized by 164-175 body annuli; 165-178 dorsal annuli; 13-17 caudal annuli with absence of caudal autotomy. In addition, 2-4 lateral annuli; 45-54 mid-body segments; 39-50 posterior segments; 4-5 head's plates and 4-6 pre-cloacal pores were recorded in both males and females without gender difference. The present study revealed the widespread distribution of this species in the studied region, since land topography in this area is characterized by the absence of any natural barriers which could restrict the spread of this amphisbaenian lizard D. zarudnyi. PMID- 30294212 TI - Effect of gastric and small intestinal digestion on lactic acid bacteria activity in a GIS1 simulator. AB - The selection of probiotic strains resistant to gastrointestinal transit is an important stage when developing supplements that contain viable biomass. A total of six strains belonging to different genotypes were tested and compared with both a positive and negative control (Lactobacillus plantarum 5s). Significant differences were found between strains as a result of gastrointestinal transit using the in vitro GIS1 static simulator. The Lactobacillus rhamnosus 428ST strain showed maximum viability as a result of in vitro transit, featuring a survival capacity value, Cs, of over 50 +/- 0.01%. The remaining genotypes that were tested showed significant reductions in the enzymes and bile salts at the time of action. The value of the survivability capacity was directly correlated with the synthesis of exopolysaccharides and lactic acid. The test results of the GIS1 system have been compared with those of other studies on gastrointestinal transit resistance that used dynamic models. PMID- 30294213 TI - Biological activity of Cymbopogon schoenanthus essential oil. AB - Introduction: A number of plant species, including Cymbopogon schoenanthus, are traditionally used for the treatment of various diseases. C. schoenanthus is currently, traded in the Saudi markets, and thought to have medicinal value. This study aimed at investigating the biological activities of C. schoenanthus against both Gram-positive and Gram-negative bacteria and to identify its chemical ingredients. Materials and methods: The inhibitory effects of water extracts of C. schoenanthus essential oils were evaluated against ten isolates of both Gram positive and Gram-negative bacteria using the agar well diffusion and dilution methods. The minimum inhibitory concentration (MIC) was assayed using the Broth microdilution test on five of the ten isolates. The death rates were determined by the time kill assay, done according to the Clinical Laboratory Standards Institute (CLSI) guidelines. The chemical composition of the essential oils of the plant was performed using GC/MS. Results: The C. schoenanthus essential oil was effective against Escherichia coli, Staphylococcus aureus, methicillin sensitive (MSSA) S. aureus (MRSA) and Klebsiella pneumoniae. The essential oil was not effective against Staphylococcus saprophyticus at the highest concentration applied of >150 MUg/ml. The MIC values were as follows: 9.37 MUg/ml for E. coli 4.69 MUg/ml for S. aureus (MRSA), 2.34 mg/ml for MSSA and 2.34 MUg/ml for K. pneumoniae. The time-kill assay indicated that there was a sharp time dependent decline in K. pneumoniae counts in the presence of the oil. This is in contrast to a gradual decline in the case of S. aureus under the same conditions. The eight major components of the essential oil were: piperitone (14.6%), cyclohexanemethanol (11.6%), beta-elemene (11.6%), alpha-eudesmol (11.5%), elemol (10.8%), beta-eudesmol (8.5%), 2-naphthalenemethanol (7.1%) and gamma-eudesmol (4.2%). Conclusion: The results of the present study provide a scientific validation for the traditional use of C. schoenanthus as an antibacterial agent. Future work is needed to investigate and explore its application in the environmental and medical fields. In addition, to evaluating the efficacy of the individual ingredients separately to better understand the underlying mechanism. PMID- 30294215 TI - Spatial and seasonal variations in the biofunctional lipid substances (fucoxanthin and fucosterol) of the laboratory-grown edible Japanese seaweed (Sargassum horneri Turner) cultured in the open sea. AB - This work studied the effect of spatial and seasonal differences on the accumulation of functional lipid components in Sargassum horneri (Turner), an edible Japanese seaweed popularly called Akamoku. S. horneri obtained from Samenoura bay area of Japan was laboratory cultured to evaluate the effect of temperature on the accumulation of total lipids (TL), fucoxanthin (Fx) and fucosterol (Fs) by the alga. The laboratory cultured 3 month old S. horneri were cultured in the open sea in two different geographical locations off Usujiri and Matsushima to evaluate the monthly variations, over a year, in their TL, Fx and Fs contents. S. horneri grown off the Usujiri area accumulated the maximum TL close to 193 mg g-1 dry weight during the coldest part of the year. Fx and Fs contributed 5.6% and 16.2% of the TL in S. horneri harvested off Usujiri in February. Further, in spite of being the same species and parent stock, S. horneri grown off the Matsushima area accumulated less TL, Fx and Fs as compared to their Usujiri counterparts. Our study clearly indicates the role of temperature and light apart from nutritional profile and depth of waters where the seaweed was grown on the accumulation of functional lipid components in S. horneri. PMID- 30294214 TI - Optimization of conditions to extract high quality DNA for PCR analysis from whole blood using SDS-proteinase K method. AB - In case of studies associated with human genetics, genomics, and pharmacogenetics the genomic DNA is extracted from the buccal cells, whole blood etc. Several methods are exploited by the researchers to extract DNA from the whole blood. One of these methods, which utilizes cell lysis and proteolytic properties of sodium dodecyl sulfate (SDS) and proteinase K respectively, might also be called SDS-PK method. It does not include any hazardous chemicals such as phenol or chloroform and is inexpensive. However, several researchers report the same method with different formulas and conditions. During our experiments with whole blood DNA extraction we experienced problems such as protein contamination, DNA purity and yield when followed some SDS-PK protocols reported elsewhere. A260/A280 and A260/A230 ratios along with PCR amplification give a clear idea about the procedure that was followed to extract the DNA. In an effort to increase the DNA purity from human whole blood, we pointed out some steps of the protocol that play a crucial role in determining the extraction of high quality DNA. PMID- 30294216 TI - Growth inhibitory properties of lactose fatty acid esters. AB - Sugar esters are biodegradable, nonionic surfactants which have microbial inhibitory properties. The influence of the fatty acid chain length on the microbial inhibitory properties of lactose esters was investigated in this study. Specifically, lactose monooctanoate (LMO), lactose monodecanoate (LMD), lactose monolaurate (LML) and lactose monomyristate (LMM) were synthesized and dissolved in both dimethyl sulfoxide (DMSO) and ethanol. Minimum inhibitory concentrations (MIC) and minimum bactericidal concentrations (MBC) were determined in growth media. LML was the most effective ester, exhibiting MIC values of <0.05 to <5 mg/ml for each Gram-positive bacteria tested (Bacillus cereus, Mycobacterium KMS, Streptococcus suis, Listeria monocytogenes, Enterococcus faecalis, and Streptococcus mutans) and MBC values of <3 to <5 mg/ml for B. cereus, M. KMS, S. suis, and L. monocytogenes. LMD showed MIC and MBC values of <1 to <5 mg/ml for B. cereus, M. KMS, S. suis, L. monocytogenes, and E. faecalis, with greater inhibition when dissolved in ethanol. LMM showed MIC and MBC values of <1 to <5 mg/ml for B. cereus, M. KMS, and S. suis. LMO was the least effective showing a MBC value of <5 mg/ml for only B. cereus, though MIC values for S. suis and L. monocytogenes were observed when dissolved in DMSO. B. cereus and S. suis were the most susceptible to the lactose esters tested, while S. mutans and E. faecalis were the most resilient and no esters were effective on Escherichia coli O157:H7. This research showed that lactose esters esterified with decanoic and lauric acids exhibited greater microbial inhibitory properties than lactose esters of octanoate and myristate against Gram-positive bacteria. PMID- 30294217 TI - In vivo fertilizing ability of stallion spermatozoa processed by single layer centrifugation with Androcoll-ETM. AB - A colloid with a species specific silane-coated, silica-based formulation, optimized for stallion (Androcoll-ETM), enables a better sub-population of spermatozoa to be selected from stallion ejaculates. However, such a practice has not been critically evaluated in stallions with fertility problems. In this study we evaluate whether single-layer centrifugation (SLC) through Androcoll-ETM could be used to enhance fertility rates in a subfertile stallion. Ejaculates were obtained from two different stallions, one Lusitano (fertile) and one Sorraia (subfertile), with distinct sperm characteristics and fertility. Motility, morphology, plasma membrane structural (eosin-nigrosin) and functional integrity (HOS test), mitochondrial functionality (Deltapsim; JC-1) and longevity (motility after 72 h cooling) after centrifugation in Androcoll-ETM, as well as pregnancy rates obtained after artificial insemination (AI), with and without (control group) SLC-treated sperm were assessed. The effect of SLC on sperm characteristics, and fertility results were evaluated by ANOVA and Fisher procedures, respectively. Our results showed that SLC-selected sperm did not differ from the raw semen in terms of viability, morphology, response to hypo osmotic conditions (HOS test) and mitochondrial membrane potential (?DeltaPsimit; JC-1). Sperm motility in cooled samples was not improved by SLC treatment. Our data show that SLC through Androcoll-ETM has no effect on pregnancy rates in the stallions used in this trial. PMID- 30294218 TI - Expression of variable viruses as herpes simplex glycoprotein D and varicella zoster gE glycoprotein using a novel plasmid based expression system in insect cell. AB - Several prokaryotic and eukaryotic expression systems have been used for in vitro production of viruses' proteins. However eukaryotic expression system was always the first choice for production of proteins that undergo post-translational modification such as glycosylation. Recombinant baculoviruses have been widely used as safe vectors to express heterologous genes in the culture of insect cells, but the manipulation involved in creating, titrating, and amplifying viral stocks make it time consuming and laborious. Therefore, to facilitate rapid expression in insect cell, a plasmid based expression system was used to express herpes simplex type 1 glycoprotein D (HSV-1 gD) and varicella zoster glycoprotein E (VZV gE). Recombinant plasmids were generated, transfected into insect cells (SF9), and both glycoproteins were expressed 48 h post-infection. A protein with approximately molecular weight of 64-kDa and 98-kDa for HSV-1 gD and VZV gE respectively was expressed and confirmed by SDS. Proteins were detected in insect cells cytoplasm and outer membrane by immunofluorescence. The antigenicity and immunoreactivity of each protein were confirmed by immunoblot and ELISA. Results suggest that this system can be an alternative to the traditional baculovirus expression for small scale expression system in insect cells. PMID- 30294219 TI - Effects of water-deficit stress and paclobutrazol on growth, relative water content, electrolyte leakage, proline content and some antioxidant changes in Curcuma alismatifolia Gagnep. cv. Chiang Mai Pink. AB - Effects of water-deficit stress and paclobutrazol (PBZ) on the physiological and biochemical changes in Curcuma alismatifolia Gagnep. cv. Chiang Mai Pink (Zingiberaceae) were investigated. One hundred rhizomes were grown for 30-35 days and then divided into the following 4 treatments: (1) well-watered, (2) not watered, (3) well-watered and treated with 1500 ppm PBZ being applied once to the soil, and (4) not watered but treated with 1500 ppm PBZ. After 50 days of growth, watering was withheld for 30 days. After water stress was initiated, plant height, plant fresh weight, soil water content, relative water content (RWC), electrolyte leakage (EL), proline content, vitamin C and E content, as well as the activities of catalase (CAT) and superoxide dismutase (SOD) in the leaves were determined every 10 days. The results showed that water-deficit stress decreased plant height and plant fresh weight, whereas this stress and PBZ did not result in a decrease in these parameters. Water stress reduced RWC, but induced EL and proline content in the leaves. However, the leaves showed opposite results when PBZ was added to the treatments. Some antioxidants such as vitamin C, vitamin E, and the activities of CAT and SOD were induced in the leaves by PBZ. Moreover, the content of vitamin C, vitamin E and CAT activity were higher in relation to water-deficit stress and PBZ treatments. This indicates that PBZ induced a number of some physiological and biochemical adaptations (maintaining growth and RWC, decreasing EL and proline content, increasing the vitamin C and vitamin E levels, and CAT and SOD activities) that enable the Curcuma plant to tolerate drought.

AB - Rhazya stricta Decne is an important medicinal species used in indigenous medicinal herbal drugs to cure various diseases in South Asia (Pakistan, India and Afghanistan) and in the Middle East (e.g. Saudi Arabia, Qatar, United Arab Emirates (UAE), Iran and Iraq). Some of its alkaloids have been reported to have anticancerous properties. The aim of our study is to examine the morphological and taxonomical parameters for R. stricta in the Saudi Arabia; concentrations and distributions of some secondary metabolites; and also to determine the antioxidant and free radical scavenging activity. The results of present study showed that there was no influence of environment on the structure of stomata and trichomes as studying species with R. stricta. In conclusion our study shows no trichomes on leaf of R. stricta it is glabrous, whereas, variations between many secondary metabolites such as flavonoids and phenolic compounds occurred in response to changing climatic conditions. PMID- 30294221 TI - Bioengineered silver nanoparticles using Curvularia pallescens and its fungicidal activity against Cladosporium fulvum. AB - Microorganisms based biosynthesis of nanomaterials has triggered significant attention, due to their great potential as vast source of the production of biocompatible nanoparticles (NPs). Such biosynthesized functional nanomaterials can be used for various biomedical applications. The present study investigates the green synthesis of silver nanoparticles (Ag NPs) using the fungus Curvularia pallescens (C. pallescens) which is isolated from cereals. The C. pallescens cell filtrate was used for the reduction of AgNO3 to Ag NPs. To the best of our knowledge C. pallescens is utilized first time for the preparation of Ag NPs. Several alkaloids and proteins present in the phytopathogenic fungus C. pallescens were mainly responsible for the formation of highly crystalline Ag NPs. The as-synthesized Ag NPs were characterized by using UV-Visible spectroscopy, X-ray diffraction and transmission electron microscopy (TEM). The TEM micrographs have revealed that spherical shaped Ag NPs with polydisperse in size were obtained. These results have clearly suggested that the biomolecules secreted by C. pallescens are mainly responsible for the formation and stabilization of nanoparticles. Furthermore, the antifungal activity of the as prepared Ag NPs was tested against Cladosporium fulvum, which is the major cause of a serious plant disease, known as tomato leaf mold. The synthesized Ag NPs displayed excellent fungicidal activity against the tested fungal pathogen. The extreme zone of reduction occurred at 50 MUL, whereas, an increase in the reduction activity is observed with increasing the concentration of Ag NPs. These encouraging results can be further exploited by employing the as synthesized Ag NPs against various pathogenic fungi in order to ascertain their spectrum of fungicidal activity. PMID- 30294222 TI - Changes in protein quantities of phosphoenolpyruvate carboxylase and Rubisco activase in various wheat genotypes. AB - In early seedlings of wheat genotypes two isoforms of Rubisco activase with molecular weights of 42 and 46 kDa are expressed. Amounts of both isoforms significantly increase in early seedlings of the durum wheat genotype Barakatli 95 exposed to salt stress. But at the beginning of the tillering stage, the changes in quantities of both RCA isoforms are different in durum and bread wheat genotypes subjected to a 3-day drought stress. In the leaves of the early seedlings of the studied wheat genotypes exposed to drought stress quantities of PEPC subunits increase compared to the control but they remain relatively stable in early roots and germinating seeds. However, quantities of its subunits decrease sharply in roots and germinating seeds of early seedlings under the influence of 100 mM NaCl. In flag leaves and ear elements of the Barakatli-95 genotype grown under normal water supply conditions protein quantities of PEPC subunits change differently depending on time. Changes in protein quantities of RCA, PEPC and Rubisco enzymes have been studied comparatively in ear elements and flag leaves after the fourth day of anthesis. PMID- 30294223 TI - Changes in radical scavenging activity of normal, endoreduplicated and depolyploid root tip cells of Allium cepa. AB - The plant cell responds to abiotic stress conditions by adjusting its cellular metabolism and various defensive mechanisms. Cellular metabolism involves changes in the cell cycle, in which the cell undergoes repeated rounds of endocycles leading to polyploidization. Defense mechanisms such as role of antioxidants are a key to understand plant adaptation. The present work describes endoreduplication and radical scavenging activity as two different defense mechanisms adapted by plants for their survival under stress condition. The work describes linkage of these two processes with each other under abiotic stress. Endoreduplicated root tip cells of Allium cepa were depolyploidized by exogenous phytohormones. Further, free radical scavenging activity from normal, endoreduplicated and depolyploidized root tips cells was observed to understand the role of phytohormones. Elevated free radical scavenging potential was observed in endoreduplicated cells compared to normal and depolyploidized cells. Based on these results, it was concluded that endoreduplication and antioxidant pathways are linked with each other through phytohormonal activities. The concentration of auxin and cytokinin regulates the activity of ascorbate oxidase enzyme, which in turn maintains the concentration of AsA within the cell. AsA level directs the prolyl-hydroxylation process of cell division proteins in quiescent center cells either toward endoreduplication process or cell division process.

AB - Engineered iron oxide nanoparticles (IO-NPs) have been used extensively for environmental remediation. It may cause the release IO-NPs to the environment affecting the functions of ecosystems. Plants are an important component of ecosystems and can be used for the evaluation of overall fate, transport and exposure pathways of IO-NPs in the environment. In this work, the effects of engineered ferrihydrite and hematite NPs on the germination and growth of maize are studied. The germination and growth of maize were done with treatments at different concentrations of hematite and ferrihydrite NPs, namely 1, 2, 4, and 6 g/L. Biological indicators of toxicity or stress in maize seedlings were not observed in treatments with engineered hematite and ferrihydrite NPs. In contrast, the NPs treatments increased the growth of maize and the chlorophyll content, except for hematite NPs at 6 g/L, where non-significant effects were found. The translocation of engineered ferrihydrite and hematite NPs in maize stems was demonstrated using confocal laser scanning microscopy. PMID- 30294225 TI - A herbal formula, comprising Panax ginseng and bee-pollen, inhibits development of testosterone-induced benign prostatic hyperplasia in male Wistar rats. AB - A recent study reported that Panax ginseng (P. ginseng) has a protective effect on the development of benign prostatic hyperplasia (BPH). KH053 is used as a new herbal prescription consisting of P. ginseng and bee-pollen. The present study aimed to investigate whether the KH053 has inhibition effects on the development of benign prostatic hyperplasia (BPH) using an animal model with testosterone induced BPH. The experiment was carried out in forty male Wistar 7 week old rats that were divided into four groups (control group, BPH group, positive group, and KH053 group). One group was used as the control and the three groups received subcutaneous injections of testosterone 20 mg/kg for 4 weeks to induce BPH. One of them received KH053 by oral gavage daily at doses of 200 mg/kg concurrently with the testosterone. The positive group received finasteride at a dose of 1 mg/kg with testosterone. After 4 weeks, all rats were sacrificed and analyzed for prostate weight, and growth factors. Results revealed that, compared to rats in the BPH group, KH053 showed that the prostate weight and dihydrotestosterone (DHT) levels in serum were significantly decreased and the decreases in hyperplasia in prostate were also observed. In addition, immunohistochemistry (IHC) also revealed that the protein expressions of growth factors [transforming growth factor beta1 (TGF-beta1) and vascular endothelial growth factor (VEGF)] in prostate tissue were decreased in the KH053 group. In conclusion, these results suggest that KH053, comprising P. ginseng and bee-pollen, inhibits the development of BPH in Wistar rat model and might be used as functional food for BPH. PMID- 30294226 TI - Berberine improves the intestinal antioxidant status of laboratory mice, Mus musculus. AB - Oral administration of berberine chloride to mice induced an obvious enhancement in jejunal health status as expressed by the significant reduction of apoptotic cells within the intestinal villi from 15.5 to 8.3 apoptotic cell/10 VCU. In addition, jejunal antioxidant biomarkers were significantly improved as revealed by the increase in the activities of catalase and glutathione peroxidase enzymes with a concurrent increase in reduced glutathione levels and total antioxidant capacity. Also, it was associated with a significant decrease in oxidative damage biomarkers of hydrogen peroxides, malondialdehyde, nitrite/nitrate, inducible nitric oxide synthase and protein carbonyl content. Moreover, BBR treatment induced a reduction in the pro-inflammatory cytokine, TNF-alpha by about 40%. It is highly recommended to use berberine as food supplements or as natural drug therapy to enhance the antioxidant status within the intestinal tissue.

PMID- 30294228 TI - Alteration in antioxidant genes expression in some fish caught from Jeddah and Yanbu coast as a bio-indicator of oil hydrocarbons pollution. AB - The mRNA expression profile of some antioxidant genes in skin, gills, livers, and muscles of Siganus canaliculatus and Epinephelus morio was used as an indicator of petroleum hydrocarbons pollution in six areas at Jeddah and Yanbu coasts in KSA. Total petroleum hydrocarbons (TPHs) were determined in both sea water and sediments collected from the studied areas. The mRNA expression levels of superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR), glutathione peroxidase (GPx) and glutathione-S-transferase (GST) were determined. The highest level of total petroleum hydrocarbons was observed in front of the petromine refinery at Jeddah and in S. canaliculatus when compared to E. morio. There was a significant high expression level of studied antioxidant enzymes genes in the polluted areas and the level of the expression profile tended to correlate with the degree of pollution and fish species feed habit. This was confirmed by the level of MDA which in the same way increased with an increase in the level of total hydrocarbons. In conclusion; the expression profile of antioxidant enzymes of S. canaliculatus and E. morio tissues can be used as a strong bio-indicator of total hydrocarbons pollution especially in S. canaliculatus. PMID- 30294229 TI - A re-examination of the Salicornias (Amaranthaceae) of Saudi Arabia and their polymorphs. AB - During the period from 1964 to 1999 Saudi Arabian species of Salicornia were wrongly treated under the European species, S. europaea L. Recent explorations proved that there are two separate allopatric species of Salicornia in Saudi Arabia, one inhabiting the inland salt-marshes of the Najd (highlands) and the other inhabiting the Arabian Gulf Coast (lowlands). Morphological, ecological and exploratory studies confirm that they are two distinct species. The two species differ in features of bark, axillary spikes, basal vegetative segment(s) of spike, fertile segments, colour of senescent plants, and flowering, fruiting and germination phenology. As both the species have been described earlier from Iran, they are now new records for Saudi Arabia. The species are, S. persica ssp. iranica (Akhani) Kadereit & Piirainen and S. sinus-persica Akhani. S. sinus persica, of which the status was thought doubtful has been confirmed. Both the species have been described and illustrated. Each species comprises a number of polymorphs. As leaves and flowers are rudimentary, confusing species circumscriptions, a proliferation of binomials has resulted in the taxonomy of Salicornia. To mitigate such confusion, the full range of variability of the Saudi Arabian species has been documented. PMID- 30294230 TI - BmNPV-miR-415 up-regulates the expression of TOR2 via Bmo-miR-5738. AB - MicroRNAs (miRNAs) have emerged as key players in host-pathogen interaction and many virus-encoded miRNAs have been identified (computationally and/or experimentally) in a variety of organisms. A novel Bombyx mori nucleopolyhedrosis virus (BmNPV)-encoded miRNA miR-415 was previously identified through high throughput sequencing. In this study, a BmNPV-miR-415 expression vector was constructed and transfected into BmN cells. The differentially expressed protein target of rapamycin isoform 2 (TOR2) was observed through two-dimensional gel electrophoresis and mass spectrometry. Results showed that TOR2 is not directly a target gene of BmNPV-miR-415, but its expression is up-regulated by BmNPV-miR-415 via Bmo-miR-5738, which could be induced by BmNPV. PMID- 30294231 TI - Extreme effects of Seabuckthorn extracts on influenza viruses and human cancer cells and correlation between flavonol glycosides and biological activities of extracts. AB - Seabuckthorn is a medicinal plant that is used to prevent cold. It was tested for its metabolic content followed by activity against cancer and virus. The metabolic distribution of different polarity solvent extractions from the leaves was analyzed by LC-MS/MS. Flavonol glycoside contents in EA and Bu extracts were higher than MeOH and DW was observed. MeOH and EA extracts recorded high activity against influenza A/PR virus with IC50 of 7.2 MUg/mL and 10.3 MUg/mL compared with known drug Oseltamivir of 60.3 MUg/mL. A similar trend showed in influenza A/Victoria virus. In case of influenza B viruses such as B/Lee and B/Maryland, EA extract (2.87 MUg/mL and 4.5 MUg/mL of IC50) emerged strongest among other extracts and Oseltamivir (103.73 MUg/mL and 71.6 MUg/mL). Each extract showed potent anticancer activities. Interestingly, Bu extract showed stronger anticancer activity against human cancer cells such as NCL-H1299, HeLa, SKOV and Caski (8.2 MUg/mL, 8.6 MUg/mL, 18.2 MUg/mL and 9.2 MUg/mL of IC50) respectively. Correlation study reveals that aglycones and flavonol mono-glycosides highly correlated with anti-influenza activities but not correlated with anticancer activities. Reversely, di-glycosides and tri-glycosides have a high correlation with cytotoxic effect with both normal and cancer cells. Therefore, this study provides significant information concerning Seabuckthorn for further medicinal drug development. PMID- 30294232 TI - Alterations in the antibacterial potential of Synechococcus spp. PCC7942 under the influence of UV-B radiations on skin pathogens. AB - Marine organisms are seen as a source of novel drugs and the discovery of new pharmaceutical is increasingly in demand. Cyanobacteria are regarded as a potential target for this as antibacterial, antiviral, antifungal, algicide and cytotoxic activities have been reported in these organisms. They have been identified as a new and rich source of bioactive compounds belonging to diversified groups. Radiation in the UV-B range interferes with various metabolic reactions by generating free radicals and active oxygen species. These deleterious compounds are inactivated by antioxidants. Among them are the carotenoids and phycocyanin which protect against photodynamic action in different ways. Stress plays an important role in the production of bioactive metabolites from organisms. Synechococcus spp. PCC7942 was studied for antibacterial activity against various pathogenic bacteria resistant to a number of available antibiotics after being exposed to UV-B radiation. The antibacterial activity of Synechococcus spp. PCC7942 was studied on five potent skin pathogens. The highest antibacterial activity was seen the methanol extracts of 24 h UV-B exposed cultures of Synechococcus spp. PCC7942. It can be concluded that there was moderate antibacterial activity. Results showed stress, solvent and dose dependent activity. This antibacterial activity might be due to the enhanced synthesis of carotenoids and phycocyanin under UV-B stress. The purpose of the present study was to relate the inhibitory effects of the cyanobacterial compounds specifically on skin pathogens with exposure to UV-B radiation as UV protecting compounds are already reported in these organisms. PMID- 30294233 TI - Foot care practices of diabetic patients in Saudi Arabia. AB - Diabetic foot is a serious complication that causes lower extremity amputations. The aim of this study was to identify the patient's awareness about risk factors for diabetic foot disease and to explore the knowledge and foot care practices among diabetic patients in a Saudi population. This cross-sectional study was conducted in King Khalid University Hospital (KKUH), King Abdulaziz University Hospital (KAUH), King Fahad Medical City, National Guard Hospital, Military Hospital, and Prince Salman Hospital capital city of Saudi Arabia. Patients were eligible if they had diabetes foot disease, signed the consent form, and completed the questionnaire. We selected 350 patients from different hospitals between November-2011 and April-2012. The majority of patients (68%) were selected from King Saud University hospitals. The mean age of patients was 50.87 +/- 15.9 years with a range of 20-90 years. The majority of patients were male (64.3%) and had a family history of hypertension (55.4%), high total cholesterol (58.6%), and other diabetes (58.9%). A family history of smoking, a major risk factor for diabetic foot, was found in 20.3% of cases. Sixty percent of the patients were using oral medications, 27.1% were using insulin therapy, 10% were using both oral and insulin therapies, and 10% were on diet. In our study, 19.4% of participants were illiterate while 80.6% had a high school or university level education. Our findings also revealed that some patients had a lack of knowledge concerning diabetic foot disease and future complications. Patients are unaware of the risk factors for diabetes foot and practice poor foot care. Awareness programs should be mandatory in all hospitals and diabetes clinics to help compensate for the lack of awareness and lack of podiatric educational services. Such programs may decrease the risk of diabetes foot disease. PMID- 30294234 TI - Effect of Zinc nanoparticles on oxidative stress-related genes and antioxidant enzymes activity in the brain of Oreochromis niloticus and Tilapia zillii. AB - This study was carried out to determine the median lethal concentrations (LC50) of Zinc nanoparticles (ZnNPs) on Oreochromis niloticus and Tilapia zillii. The biochemical and molecular potential effects of ZnNPs (500 and 2000 MUg L-1) on the antioxidant system in the brain tissue of O. niloticus and T. zillii were investigated. Four hundred fish were used for acute and sub-acute studies. ZnNP LC50 concentrations were investigated in O. niloticus and T. zillii. The effect of 500 and 2000 MUg L-1 ZnNPs on brain antioxidants of O. niloticus and T. zillii was investigated. The result indicated that 69 h LC50 was 5.5 +/- 0.6 and 5.6 +/- 0.4 for O. nilotica and T. zillii, respectively. Fish exposed to 500 MUg L-1 ZnNPs showed a significant increase in reduced glutathione (GSH), total glutathione (tGSH) levels, superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR), glutathione peroxidase (GPx) and glutathione-S transferase (GST) activity and gene expression. On the contrary, malondialdehyde (MDA) levels significantly decreased. Meanwhile, fish exposed to 2000 MUg L-1 ZnNPs showed a significant decrease of GSH, tGSH levels, SOD, CAT, GR, GPx and GST activity and gene expression. On the contrary, MDA levels significantly increased. It was concluded that, the 96 h LC50 of ZnNPs was 5.5 +/- 0.6 and 5.6 +/- 0.4 for O. nilotica and T. zillii, respectively. ZnNPs in exposure concentrations of 2000 MUg/L induced a deleterious effect on the brain antioxidant system of O. nilotica and T. zillii. In contrast, ZnNPs in exposure concentrations of 500 MUg L-1 produced an inductive effect on the brain antioxidant system of O. nilotica and T. zillii. PMID- 30294235 TI - Superintendence of antimicrobial resistance observed in bacterial flora isolated from human faecal carriage in Vellore, India. AB - A frequent cross-sectional study was conducted to determine the patterns of antimicrobial resistance in 296 bacterial strains isolated from in-patient faecal samples of Government Vellore Medical College and Hospital, Vellore. Isolation and identification of bacterial strains were done using enrichment media, selective media, and biochemical tests. Antimicrobial susceptibility testing by the disc diffusion method and minimal inhibitory concentration method was conducted and the strains were subjected to extended spectrum beta-lactamases screening. Antibiotic sensitivity pattern of Staphylococcus spp. showed oxacillin resistance. Almost all the strains were sensitive to linezolid, vancomycin, gentamycin and chloramphenicol. In gram negative isolates ciprofloxacin and tobramycin showed better sensitivity and ceftazidime showed a higher percentage of resistance by MIC. Out of 250 isolates, Enterobacteriaceae showed positive for 86/250, 82/250 and 94/250 isolates and 3/10, 4/10 and 4/10 non-Enterobacteriaceae isolates were found to be positive for CTX-M gene, TEM gene and SHV gene, respectively. This study helps to assess/analyse the relation between the spectrum of microorganisms present in various grades of faecal carriage and their susceptibility pattern in this part of the Vellore town. PMID- 30294236 TI - Pod, seed traits and cytotaxonomic studies of some Vicia narbonensis L. accessions (Fabaceae). AB - This study aimed to characterize eight accessions of Vicia narbonensis L. originated from different Mediterranean countries. The cytology of these species is rarely known despite the fact of its great socio-economical and ecological interest in these arid and semi-arid zones. This work aimed mainly to characterize the karyotype, morphological pod and seed traits of the species. Karyotypes of all accessions were similar to a diploid number of 2n = 2x = 14. All the accessions have submetacentric chromosomes with a secondary constriction attached to the long arm of pair VII close to the centromere. Variation in chromosome size was observed; it ranged from 5.86 MUm to 7.62 MUm. Indices of karyotype asymmetry were calculated as the total form percentage (TF%) and symmetric indices (Syi) which ranged from 33.75% to 35.42% and from 51.01% to 54.85%, respectively. The predominance of submetacentric chromosomes indicated that the karyotype is symmetrical and can be considered as primitive. However, the analysis of quantitative parameters measured on pods and seeds showed a significant variation between accessions. A relationship between centromeric index and the pod beak length was found. Estimation of phenotypic diversity using the Shannon diversity index (H') showed that the length, the seed color and the number of seeds per pod are the most polymorphic traits with respectively, H' = 0.92, 0.80 and 0.83. Cluster analysis of karyological, pod and seed traits showed four groups of accessions. This clustering is partially due to the geographical origin of the studied accessions. The variation in chromosome size, pod and seed traits could offer potentially valuable genetic resources for the improvement of V. narbonensis which is considered as neglected and underutilized crop species (NUCS). PMID- 30294237 TI - Molecular typing of phlebotomine sand flies in al-madinah and asir regions, Saudi Arabia using PCR-RFLP of 18S ribosomal RNA gene. AB - Studies on the distribution of sand flies are important for the control of leishmaniasis in endemic and neighboring areas. In the present study polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) was used to identify the distribution of sand flies in Al-Madinah and Asir Regions of Saudi Arabia using PCR-RFLP of 18S ribosomal RNA gene. Based on the morphological characteristics, the sand flies were differentiated into seven species viz., Phlebotomus papatasi, Phlebotomus sergenti, Phlebotomus bergeroti, Sergentomyia clydei, Sergentomyia antennata, Sergentomyia fallax and Sergentomyia schwetzi. PCR-RFLP of 18S ribosomal RNA (rRNA) genes with eight different restriction enzymes resulted in species-specific agarose gel electrophoresis banding patterns. Of the eight restriction enzymes used, not a single restriction enzyme by itself could separate species belonging to the same genera (like P. papatasi and P. sergenti by AseI) as well as those belonging to different genera (like P. papatasi and S. clydei by AseI). We therefore conclude that the genetic diversity within sand fly species based on PCR-RFLP technique was nonspecific. Studies are in progress to study the viability of alternate techniques like low-stringency single specific primer polymerase chain reaction which can be used for molecular typing. PMID- 30294238 TI - Description of a methanotrophic strain BOH1, isolated from Al-Bohyriya well, Al Ahsa City, Saudi Arabia. AB - Methanotrophic bacteria have a unique ability to utilize methane as their carbon and energy sources. Therefore, methanotrophs play a key role in suppressing methane emissions from different ecosystems and hence in alleviating the global climate change. Despite methanotrophs having many ecological, economical and biotechnological applications, little is known about this group of bacteria in Al Ahsa. Therefore, the main objective of the current work was to expand our understanding of methane oxidizing bacteria in Al-Ahsa region. The specific aim was to describe a methanotrophic strain isolated from Al-Bohyriya well, Al-Ahsa using phenotypic, genotypic (such as 16S rRNA and pmoA gene sequencing) and phylogenetic characterization. The results indicated that the strain belongs to the genus Methylomonas that belongs to Gammaproteobacteria as revealed by the comparative sequence analysis of the 16S rRNA and pmoA genes. There is a general agreement in the profile of the phylogenetic trees based on the sequences of 16srRNA and pmoA genes of the strain BOH1 indicating that both genes are efficient taxonomic marker in methanotrophic phylogeny. The strain possesses the particulate but not the soluble methane monooxygenase as a key enzyme for methane metabolism. Further investigation such as DNA:DNA hybridization is needed to assign the strain as a novel species of the genus Methyomonas and this will open the door to explore the talents of the strain for its potential role in alleviating global warming and biotechnological applications in Saudi Arabia such as bioremediation of toxic by-products released in oil industry. In addition, the strain enhances our knowledge of methanotrophic bacteria and their adaptation to desert ecosystems. PMID- 30294239 TI - Ultrastructural differentiation of spermiogenesis in Scincus scincus (Scincidae, Reptilia). AB - Background: Knowledge of spermiogenesis in reptiles, especially in lizards, is very limited. Lizards found in Arabian deserts have not been considered for detailed studies due to many reasons and the paucity of these animals. Therefore, we designed a study on the differentiation and morphogenesis of spermiogenesis, at an ultrastructural level, in a rare lizard species, Scincus scincus. Results: The spermiogenesis process includes the development of an acrosomal vesicle, aggregation of acrosomal granules, formation of subacrosomal nuclear space, and nuclear elongation. A role for manchette microtubules was described in nuclear shaping and organelle movement. During head differentiation, the fine granular chromatin of the early spermatid is gradually replaced by highly condensed contents in a process called chromatin condensation. Furthermore, ultrastructural features of sperm tail differentiation in S. scincus were described in detail. The commencement was with caudal migration toward centrioles, insertion of the proximal centriole in the nuclear fossa, and extension of the distal centrioles to form the microtubular axoneme. Subsequently, tail differentiation consists of the enlargement of neck portion, middle piece, the main and end pieces. Conclusions: This study aids in the understanding of different aspects of spermiogenesis in the lizard family and unfurls evolutionary links within and outside reptiles. PMID- 30294240 TI - Statistical optimization of antifungal iturin A production from Bacillus amyloliquefaciens RHNK22 using agro-industrial wastes. AB - Biosurfactants are secondary metabolites with surface active properties and have wide application in agriculture, industrial and therapeutic products. The present study was aimed to screen bacteria for the production of biosurfactant, its characterization and development of a cost effective media formulation for iturin A production. A total of 100 bacterial isolates were isolated from different rhizosphere soil samples by enrichment culture method and screened for biosurfactant activity. Twenty isolates were selected for further studies based on their biosurfactant activity [emulsification index (EI%), emulsification assay (EA), surface tension (ST) reduction] and antagonistic activity. Among them one potential isolate Bacillus sp. RHNK22 showed good EI% and EA with different hydrocarbons tested in this study. Using biochemical methods and 16S rRNA gene sequence, it was identified as Bacillus amyloliquefaciens. Presence of iturin A in RHNK22 was identified by gene specific primers and confirmed as iturin A by FTIR and HPLC. B. amyloliquefaciens RHNK22 exhibited good surface active properties and antifungal activity against Sclerotium rolfsii and Macrophomina phaseolina. For cost-effective production of iturin A, 16 different agro industrial wastes were screened as substrates, and Sunflower oil cake (SOC) was favouring high iturin A production. Further, using response surface methodology (RSM) model, there was a 3-fold increase in iturin A production (using SOC 4%, inoculum size 1%, at pH 6.0 and 37 degrees C temperature in 48 h). This is the first report on using SOC as a substrate for iturin A production. PMID- 30294241 TI - Pollination ecology of Acacia gerrardii Benth. (Fabaceae: Mimosoideae) under extremely hot-dry conditions. AB - Talh trees (Acacia gerrardii Benth.) are acacias that are native to the arid and semiarid Africa and west Asia. We investigated the flowering biology, pod set and flower visitors of Talh and discussed the role of these visitors in pollen transfer. The Talh trees blossomed laterally on the nodes of one-year-old twigs. Each node produced 21 flower buds seasonally. Each flower bud opened to a flower head (FH) of 60 florets. The bagged FHs podded significantly (p ? 0.05) less than did the unbagged FHs. The FHs were visited by 31 insect species (25 genera, 16 families and 5 orders). The major taxa were honeybees, megachilids, butterflies, ants, beetles and thrips. Each of honeybees, megachilids and beetles showed a significant (p ? 0.05) hourly pattern, while each of butterflies, ants and thrips had no hourly pattern (p > 0.05). Furthermore, some birds and mammals touched the Talh FHs. Talh trees evolved a mass flowering behavior to face pre- and post flowering obstacles. Megachilids seemed to play the major effort of zoophily because of their relatively high numbers of individuals and species and their effective movement behavior on the FH surface. Nevertheless, honeybees and other insects and vertebrate taxa also contributed to the pollen transfer. These results greatly contribute to our understanding of the pollination ecology of acacias, especially Arabian acacias.

PMID- 30294243 TI - Indian philosophical foundations of spirituality at the end of life. AB - Growing understanding of spirituality at the end of life demands more theoretical research on the subject. Empirical studies have highlighted the need for exploring philosophical and cultural concepts to facilitate a fuller understanding of spirituality at the end of life. This paper explores Indian philosophy to inform the conceptualisation of spirituality at the end of life in the Indian context. Three key themes from discourses on spirituality at the end of life have been analysed: the concept of the human person, the purpose of life and the meaning of death. The human person is from and of the Divine, eternal and is capable of cognition and experience. The purpose of human life is to unite with the ultimate Reality, the Divine, by living life righteously according to prescribed ways and by achieving detachment from the illusion of the world. Death is part of life and not that which ends it. The moment of death is an opportunity for the ultimate transformation, Moksha. Analysing these philosophical foundations can provide the contextual frame for understanding the spiritual needs of palliative care patients and their families and the possibility of developing culturally relevant approaches to providing spiritual care at the end of life. PMID- 30294244 TI - Development of an epiphyte indicator of nutrient enrichment: threshold values for seagrass epiphyte load. AB - Metrics of epiphyte load on macrophytes were evaluated for use as quantitative biological indicators for nutrient impacts in estuarine waters, based on review and analysis of the literature on epiphytes and macrophytes, primarily seagrasses, but including some brackish and freshwater rooted macrophyte species. An approach is presented that empirically derives threshold epiphyte loads which are likely to cause specified levels of decrease in macrophyte response metrics such as biomass, shoot density, percent cover, production and growth. Data from 36 studies of 10 macrophyte species were pooled to derive relationships between epiphyte load and -25 and -50% seagrass response levels, which are proposed as the primary basis for establishment of critical threshold values. Given multiple sources of variability in the response data, threshold ranges based on the range of values falling between the median and the 75th quantiles of observations at a given seagrass response level are proposed rather than single, critical point values. Four epiphyte load threshold categories - low, moderate, high, very high, are proposed. Comparison of values of epiphyte loads associated with 25 and 50% reductions in light to macrophytes suggest that the threshold ranges are realistic both in terms of the principle mechanism of impact to macrophytes and in terms of the magnitude of resultant impacts expressed by the macrophytes. Some variability in response levels was observed among climate regions, and additional data collected with a standardized approach could help in the development of regionalized threshold ranges for the epiphyte load indicator. PMID- 30294245 TI - Emergy-based indicators for evaluating ecosystem health: A case study of three benthic ecosystem networks influenced by coastal upwelling in northern Chile (SE Pacific coast). AB - It has been hypothesized that ecosystem health describes the state in which all processes operating within an ecosystem are functioning at a level of optimum efficiency to maximize system empower. In this study, systems analysis of networks and information flows is used within this definition of ecosystem health to assess the condition of the benthic ecosystems in three coastal bays in northern Chile. These highly productive ecosystems are characterized by the inflow of cold, nutrient-rich waters of low oxygen concentration derived from coastal upwelling of deep waters and the interruption of upwelling flow during El Nino events when warmer waters with higher oxygen and lower nutrient concentrations enter these coastal systems. Also, these ecosystems support important artisanal benthic fisheries and are affected by industrial activities in the coastal zone. Energy Systems Theory (EST) and Emergy Analysis (EA) were applied to quantify the health of these benthic ecosystems and evaluate differences in their structure, organization and functional capacities, which are related to their emergy signatures. The marked dominance of these benthic ecosystems by nitrate from upwelling resulted in unbalanced emergy signatures, suggesting less development and system diversity compared to other coastal ecosystems with more balanced emergy signatures. Macro-descriptors and network properties, such as emergy-based ascendency and the quality-adjusted Shannon diversity index were highest for Mejillones Bay, followed by Antofagasta and then Tongoy Bay. The Average Mutual Information (AMI) index adjusted for energy quality and the emergy-based A/C (ascendency to capacity) ratio, were higher for Tongoy Bay, suggesting functional differences in health among the three ecosystems. Thus, the emergy-based macro descriptors and other indicators used in our analysis indicate that the benthic networks examined have different structural and functional characteristics that lead to different characterizations of their states of health. As a result of this complexity, management policies should be implemented within a systemic context for analysis that considers all the factors determining the relative health of each ecosystem. PMID- 30294246 TI - A case-control study on the association of abdominal obesity and hypercholesterolemia with the risk of colorectal cancer. AB - BACKGROUND: Obesity has frequently been associated with the dyslipidemic state and with the risk of various chronic diseases. OBJECTIVE: The objective of this study was to determine the relationship between obesity and blood lipids with a risk of colorectal cancer (CRC). METHODOLOGY: Histologically confirmed CRC patients from five local hospitals were matched with cancer-free controls for age, gender, and ethnicity (n = 140: 280). The study participants underwent physical assessment for the presence of obesity and 10 mL of fasting blood was drawn for blood lipid analysis. RESULTS: In this study, abdominal obesity significantly doubled the risk of CRC (adjusted odds ratio [AOR] =1.69, 95% confidence interval [CI] = 1-2.83). Hypercholesterolemia and low high-density lipoprotein cholesterol (HDL) increased the risk of CRC more than twofolds (AOR = 2.6, 95% CI = 1.7-3.9 and AOR = 3.8, 95% CI = 2.3-6.3, respectively). Abdominal obesity and hypercholesterolemia synergically doubled the risk of CRC (AOR = 2.0, 95% CI = 1-4). Low-HDL has shown no synergic association with other dyslipidemic states with an increased CRC risk. CONCLUSION: Improving abdominal obesity, hypercholesterolemia, and low HDL may be a clinically relevant strategy to reduce the risk of CRC among Malaysians. PMID- 30294247 TI - Role of aberrant glycosylation enzymes in oral cancer progression. AB - BACKGROUND: Carcinogenesis, a multistep process involves sequential changes during neoplastic transformation. The various hallmarks of cancer aid in cell survival, proliferation, and dissemination. Aberrant glycosylation, a recently defined hallmark of cancer, is influenced by glycosylation enzymes during carcinogenesis. Therefore, the present study measured alpha-2,3 and alpha-2,6 sialyltransferase (ST), sialidase, and alpha-L-fucosidase activity in patients with oral precancerous conditions (OPC) and oral cancer patients. SUBJECTS: The study enrolled 100 oral cancer patients, 50 patients with OPC, 100 healthy controls, and 46 posttreatment follow-ups of oral cancer patients. Blood and saliva were collected from all the participants. MATERIALS AND METHODS: Sialidase activity was measured by spectrofluorimetric method, alpha-2,3 and alpha-2,6 ST by ELISA using biotinylated lectins, and alpha-L-fucosidase by spectrophotometric method. RESULTS: The results depicted increased levels of sialidase, alpha-2,3 and alpha-2,6 ST, alpha-L-fucosidase in patients with OPC and oral cancer patients. Receiver operating characteristic curve indicated significant discriminatory efficacy in distinguishing controls and oral cancer patients for serum and salivary sialidase and alpha-L-fucosidase activity, and serum alpha-2,6 ST. Furthermore, serum and salivary alpha-L-fucosidase activity and serum sialidase activity significantly distinguished controls and patients with OPC. Serum and salivary sialidase, alpha-L-fucosidase, and serum alpha-2,3 ST activity were higher in patients with metastasis as compared to nonmetastatic patients. Higher values of serum alpha-L-fucosidase activity were significantly associated with low-overall survival. CONCLUSION: The increased levels of enzymes correlated with tumor initiation, progression, and metastasis in oral cancer patients. The alterations in glycosyltransferases/glycosidases thus support the view of glycosylation as a hallmark of cancer. PMID- 30294249 TI - Optimization and Validation of a Microscale In vitro Method to Assess ?alpha Glucosidase Inhibition Activity. AB - Background: Microscale in vitro assays are fast, simple, and inexpensive, with reduced reagent quantities, waste, and experimental animal use. However, they have low reproducibility and low correlation with the results of in vivo models, possibly due to differences in precision and accuracy in methodologies between laboratories. Objective: The objective was the optimization and validation of an in vitro assay, carried out on microscale, to assess the inhibition of alpha glucosidase activity, which is indicative of antihyperglycemic activity. Methods: The optimization was carried out using a fractional factorial design taking into account the best inhibition percentage and the absorbance of the controls. With the optimized experimental conditions in hand, we carried out method validation. Results: The optimized conditions were as follows: enzyme concentration, 0.55 U/mL; substrate concentration, 111.5 MUM; and 17.5 min incubation at 37 degrees C. A linear range between 100 and 310.2 MUg/mL of acarbose (r2 0.994) was established. The RSD was <2% and the % error was <3%. The Z factor was >0.96. This method was applied to four plant extracts, one of which was found to be very active. Conclusion: The method was found to be accurate, precise, selective, linear, and reliable in evaluating the antihyperglycemic activity of natural extracts in vitro. PMID- 30294248 TI - The Role of Liver-Directed Therapy in Metastatic Colorectal Cancer. AB - Purpose of Review: Colorectal cancer liver metastasis is a major clinical problem, and surgical resection is the only potentially curative treatment. We seek to discuss various liver-directed therapy modalities and explore their roles in the evolving realm of treatment strategies for metastatic colorectal cancer. Recent Findings: Clinical outcomes for patients with colorectal cancer liver metastases have improved as more patients undergo potentially curative resection and as the armamentarium of systemic treatment and liver-directed therapies continues to expand. Liver-directed therapies have been developed as adjuncts to improve resectability, employed in the adjuvant setting to potentially reduce local recurrence rates, and utilized in the palliative setting with the aim to improve overall survival. Summary: Ongoing research is expected to validate the role of these evolving therapeutic options, and determine how best to sequence and when to apply these therapies. PMID- 30294250 TI - Spatio-Temporal Dynamics of Intrinsic Networks in Functional Magnetic Imaging Data Using Recurrent Neural Networks. AB - We introduce a novel recurrent neural network (RNN) approach to account for temporal dynamics and dependencies in brain networks observed via functional magnetic resonance imaging (fMRI). Our approach directly parameterizes temporal dynamics through recurrent connections, which can be used to formulate blind source separation with a conditional (rather than marginal) independence assumption, which we call RNN-ICA. This formulation enables us to visualize the temporal dynamics of both first order (activity) and second order (directed connectivity) information in brain networks that are widely studied in a static sense, but not well-characterized dynamically. RNN-ICA predicts dynamics directly from the recurrent states of the RNN in both task and resting state fMRI. Our results show both task-related and group-differentiating directed connectivity. PMID- 30294252 TI - The Small World of Adult Hippocampal Neurogenesis. AB - Making mechanistic sense of genetically complex biological systems such as adult hippocampal neurogenesis poses conceptual and many practical challenges. Transcriptomics studies have helped to move beyond single-gene approaches and have greatly enhanced the accessibility to effects of greater numbers of genes. Typically, however, the number of experimental conditions compared is small and the conclusions remain correspondingly limited. In contrast, studying complex traits in genetic reference populations, in which genetic influences are varied systematically, provides insight into the architecture of relationships between phenotypes and putative molecular mechanisms. We describe that the correlation network among transcripts that builds around the adult neurogenesis phenotype and its endophenotypes is, as expected, a small-world network and scale free. The high degree of connectivity implies that adult neurogenesis is essentially an "omnigenic" process. From any gene of interest, a link to adult hippocampal neurogenesis can be constructed in just a few steps. We show that, at a minimum correlation of 0.6, the hippocampal transcriptome network associated with adult neurogenesis exhibits only two "degrees of separation." This fact has many interesting consequences for our attempts to unravel the (molecular) causality structure underlying adult neurogenesis and other complex biological systems. Our article is not written with the expert on network theory in mind but rather aims to raise interest among neurobiologists, active in neurogenesis and related fields, in network theory and analysis as a set of tools that hold great promise for coping with the study of "omnigenic" phenotypes and systems. PMID- 30294251 TI - Selective Depletion of CREB in Serotonergic Neurons Affects the Upregulation of Brain-Derived Neurotrophic Factor Evoked by Chronic Fluoxetine Treatment. AB - Neurotrophic factors are regarded as crucial regulatory components in neuronal plasticity and are postulated to play an important role in depression pathology. The abundant expression of brain-derived neurotrophic factor (BDNF) in various brain structures seems to be of particular interest in this context, as downregulation of BDNF is postulated to be correlated with depression and its upregulation is often observed after chronic treatment with common antidepressants. It is well-known that BDNF expression is regulated by cyclic AMP response element-binding protein (CREB). In our previous study using mice lacking CREB in serotonergic neurons (Creb1TPH2CreERT2 mice), we showed that selective CREB ablation in these particular neuronal populations is crucial for drug resistant phenotypes in the tail suspension test observed after fluoxetine administration in Creb1TPH2CreERT2 mice. The aim of this study was to investigate the molecular changes in the expression of neurotrophins in Creb1TPH2CreERT2 mice after chronic fluoxetine treatment, restricted to the brain structures implicated in depression pathology with profound serotonergic innervation including the prefrontal cortex (PFC) and hippocampus. Here, we show for the first time that BDNF upregulation observed after fluoxetine in the hippocampus or PFC might be dependent on the transcription factor CREB residing, not within these particular structures targeted by serotonergic projections, but exclusively in serotonergic neurons. This observation may shed new light on the neurotrophic hypothesis of depression, where the effects of BDNF observed after antidepressants in the hippocampus and other brain structures were rather thought to be regulated by CREB residing within the same brain structures. Overall, these results provide further evidence for the pivotal role of CREB in serotonergic neurons in maintaining mechanisms of antidepressant drug action by regulation of BDNF levels. PMID- 30294253 TI - Glycine-Histidine-Lysine (GHK) Alleviates Neuronal Apoptosis Due to Intracerebral Hemorrhage via the miR-339-5p/VEGFA Pathway. AB - Glycine-histidine-lysine (GHK) is a human tripeptide that enhances wound healing, exerts neuroprotective effects against neurodegenerative disease, and improves tissue regeneration. This study examined whether GHK can alleviate injury due to intracerebral hemorrhage (ICH). Briefly, adult Wistar rats in GHK pretreatment groups were injected with GHK (1 or 10 mg/kg, i.p.) every 24 h for 3 days. Water content and intact neurons were detected in the rats 3 days after ICH, and the neurological deficit scores were examined in the rats at 4, 24, 72, and 168 h after ICH. Apoptosis was evaluated via caspase-3 immunohistochemistry, Nissl staining, and TUNEL assay. We also examined the effect of GHK on the expression of related proteins in SH-SY5Y cells via Western blotting. The expression of miR 339-5p was examined via real-time polymerase chain reaction analyses. GHK improved neurological deficits, reduced water content in the brain and inhibited neuronal apoptosis in ICH rats. It also prevented the apoptosis of SH-SY5Y cells with hemin treatment. Furthermore, GHK downregulated miR-339-5p expression, and overexpression of miR-339-5p partially reversed the anti-apoptotic effects of GHK in SH-SY5Y cells. Our findings suggest that the p38 MAPK pathway is involved in the GHK-induced downregulation of miR-339-5p, and that the miR-339-5p/VEGFA axis plays a role in preventing neuronal apoptosis following ICH injury. These findings indicate that GHK may represent a novel therapeutic strategy for ICH. PMID- 30294254 TI - Do Complexity Measures of Frontal EEG Distinguish Loss of Consciousness in Geriatric Patients Under Anesthesia? AB - While geriatric patients have a high likelihood of requiring anesthesia, they carry an increased risk for adverse cognitive outcomes from its use. Previous work suggests this could be mitigated by better intraoperative monitoring using indexes defined by several processed electroencephalogram (EEG) measures. Unfortunately, inconsistencies between patients and anesthetic agents in current analysis techniques have limited the adoption of EEG as standard of care. In attempts to identify new analyses that discriminate clinically-relevant anesthesia timepoints, we tested 1/f frequency scaling as well as measures of complexity from nonlinear dynamics. Specifically, we tested whether analyses that characterize time-delayed embeddings, correlation dimension (CD), phase-space geometric analysis, and multiscale entropy (MSE) capture loss-of-consciousness changes in EEG activity. We performed these analyses on EEG activity collected from a traditionally hard-to-monitor patient population: geriatric patients on beta-adrenergic blockade who were anesthetized using a combination of fentanyl and propofol. We compared these analyses to traditional frequency-derived measures to test how well they discriminated EEG states before and after loss of response to verbal stimuli. We found spectral changes similar to those reported previously during loss of response. We also found significant changes in 1/f frequency scaling. Additionally, we found that our phase-space geometric characterization of time-delayed embeddings showed significant differences before and after loss of response, as did measures of MSE. Our results suggest that our new spectral and complexity measures are capable of capturing subtle differences in EEG activity with anesthesia administration-differences which future work may reveal to improve geriatric patient monitoring. PMID- 30294256 TI - Andrographolide Alleviates Acute Brain Injury in a Rat Model of Traumatic Brain Injury: Possible Involvement of Inflammatory Signaling. AB - Neuroinflammation plays an important role in secondary injury after traumatic brain injury (TBI). Andrographolide (Andro), a diterpenoid lactone isolated from Andrographis paniculata, has been demonstrated to exhibit anti-inflammatory activity in neurodegenerative disorders. This study therefore aimed to investigate the potential neuroprotective effects of Andro after TBI and explore the underlying mechanisms. In our study, we used a weight-dropped model to induce TBI in Sprague-Dawley rats, the neurological deficits were assessed using modified neurological severity scores, Fluoro-Jade B (FJB) and terminal deoxynucleotidyl transferase (TdT) dUTP Nick-End Labeling (TUNEL) staining were employed to examine neuronal degeneration and apoptosis after TBI, immunofluorescence was designed to investigate microglial activation. Quantitative Real-time PCR and ELISA were conducted to detect the expression levels of pro-inflammatory cytokines, Western blot was used to examine the expression level of proteins of relative signaling pathway. Our results showed that after Andro administration, the neurological deficit was attenuated, and the cerebral edema and apoptosis in brain tissues were also decreased following TBI. Both microglial activation and the expression of pro-inflammatory cytokines were significantly inhibited by Andro after TBI. Moreover, Andro inhibited NF-kappaB p65 subunit translocation and decreased the expression levels of phosphorylated extracellular signal regulated kinase (ERK) and p38 MAPK after TBI. Altogether, this study suggests that Andro could improve neurobehavioral function by inhibiting NF-kappaB and MAPK signaling pathway in TBI, which might provide a new approach for treating brain injury. PMID- 30294257 TI - The Association Between Genetic Variation in FOXP2 and Sensorimotor Control of Speech Production. AB - Significant advances have been made in understanding the role of auditory feedback in sensorimotor integration for speech production. The neurogenetic basis of this feedback-based control process, however, remains largely unknown. Mutations of FOXP2 gene in humans are associated with severe deficits in speech motor behavior. The present study examined the associations between a FOXP2 common variant, rs6980093 (A/G), and the behavioral and event-related potential (ERP) responses to -50 and -200 cents pitch perturbations during vocal production in a sample of 133 Chinese adults. Behaviorally, the GG genotype was associated with significantly smaller vocal compensations for -200 cents perturbations relative to the AA and AG genotypes. Furthermore, both the AA and AG genotypes exhibited significant positive correlations between the degree of vocal compensation for -50 and -200 cents perturbations and the variability of normal voice fundamental frequency, whereas no such correlation existed for the GG genotype. At the cortical level, significantly larger P2 responses to -200 cents perturbations were associated with the GG genotype as compared to the AA and AG genotypes due to increased left-lateralized activity in the superior, middle, and inferior frontal gyrus, precentral gyrus, anterior cingulate cortex, middle temporal gyrus, and insula. The neurobehavioral responses to -50 cents perturbations, however, did not vary as a function of genotype. These findings present the first neurobehavioral evidence for an association between FOXP2 genetic variant and auditory-motor integration for vocal pitch regulation. The differential effects of FOXP2 genotypes at rs6980093 may reflect their influences on the weighting of feedback and feedforward control of speech production. PMID- 30294258 TI - Negative Allosteric Modulators of mGlu7 Receptor as Putative Antipsychotic Drugs. AB - The data concerning antipsychotic-like activity of negative allosteric modulators (NAMs)/antagonists of mGlu7 receptors are limited. The only available ligands for this receptor are MMPIP and ADX71743. In the present studies, we used stable cell line expressing mGlu7 receptor and it was shown that both compounds dose dependently potentiated forskolin elevated cAMP concentration in the T-REx 293 cells, showing their inverse agonist properties. Subsequently, pharmacokinetic studies were performed. Both compounds were given intraperitoneally (i.p.) at the dose of 10 mg/kg and reached Cmax 0.25-0.5 h after administration, and then they declined rapidly, ADX71743 being almost undetectable 2 h after administration, while the concentration of MMPIP was still observed, suggesting that the concentration of MMPIP was more stable. Finally, we investigated the role of both mGlu7 receptor NAMs in animal models of schizophrenia. Behavioral tests commonly used in antipsychotic drug discovery were conducted. Both tested compounds dose dependently inhibited MK-801-induced hyperactivity (MMPIP at 15 mg/kg; ADX at 5 and 15 mg/kg) and DOI-induced head twitches (MMPIP at 5, 10, 15 mg/kg; ADX at 2.5, 5, 10 mg/kg). Moreover, the same effects were noticed in novel object recognition test, where MMPIP (5, 10, 15 mg/kg) and ADX71743 (1, 5, 15 mg/kg) reversed MK-801-induced disturbances. In the social interaction test, antipsychotic activity was observed only for ADX71743 (5, 15 mg/kg). ADX71743 at the dose 2.5 mg/kg reversed MK-801-induced disruption in prepulse inhibition while MMPIP at 10 mg/kg reversed MK-801-induced disruption in spatial delayed alternation. The present studies showed that mGlu7 receptor may be considered as a putative target for antipsychotic drugs, though more studies are needed due to limited number of available ligands.

PMID- 30294255 TI - Pluripotent Stem Cell-Based Approaches to Explore and Treat Optic Neuropathies. AB - Sight is a major sense for human and visual impairment profoundly affects quality of life, especially retinal degenerative diseases which are the leading cause of irreversible blindness worldwide. As for other neurodegenerative disorders, almost all retinal dystrophies are characterized by the specific loss of one or two cell types, such as retinal ganglion cells, photoreceptor cells, or retinal pigmented epithelial cells. This feature is a critical point when dealing with cell replacement strategies considering that the preservation of other cell types and retinal circuitry is a prerequisite. Retinal ganglion cells are particularly vulnerable to degenerative process and glaucoma, the most common optic neuropathy, is a frequent retinal dystrophy. Cell replacement has been proposed as a potential approach to take on the challenge of visual restoration, but its application to optic neuropathies is particularly challenging. Many obstacles need to be overcome before any clinical application. Beyond their survival and differentiation, engrafted cells have to reconnect with both upstream synaptic retinal cell partners and specific targets in the brain. To date, reconnection of retinal ganglion cells with distal central targets appears unrealistic since central nervous system is refractory to regenerative processes. Significant progress on the understanding of molecular mechanisms that prevent central nervous system regeneration offer hope to overcome this obstacle in the future. At the same time, emergence of reprogramming of human somatic cells into pluripotent stem cells has facilitated both the generation of new source of cells with therapeutic potential and the development of innovative methods for the generation of transplantable cells. In this review, we discuss the feasibility of stem cell-based strategies applied to retinal ganglion cells and optic nerve impairment. We present the different strategies for the generation, characterization and the delivery of transplantable retinal ganglion cells derived from pluripotent stem cells. The relevance of pluripotent stem cell derived retinal organoid and retinal ganglion cells for disease modeling or drug screening will be also introduced in the context of optic neuropathies. PMID- 30294259 TI - Gadolinium Deposition in Brain: Current Scientific Evidence and Future Perspectives. AB - In the past 4 years, many publications described a concentration-dependent deposition of gadolinium in the brain both in adults and children, seen as high signal intensities in the globus pallidus and dentate nucleus on unenhanced T1 weighted images. Postmortem human or animal studies have validated gadolinium deposition in these T1-hyperintensity areas, raising new concerns on the safety of gadolinium-based contrast agents (GBCAs). Residual gadolinium is deposited not only in brain, but also in extracranial tissues such as liver, skin, and bone. This review summarizes the current evidence on gadolinium deposition in the human and animal bodies, evaluates the effects of different types of GBCAs on the gadolinium deposition, introduces the possible entrance or clearance mechanism of the gadolinium and potential side effects that may be related to the gadolinium deposition on human or animals, and puts forward some suggestions for further research. PMID- 30294262 TI - Bessel Beam Illumination Reduces Random and Systematic Errors in Quantitative Functional Studies Using Light-Sheet Microscopy. AB - Light-sheet microscopy (LSM), in combination with intrinsically transparent zebrafish larvae, is a method of choice to observe brain function with high frame rates at cellular resolution. Inherently to LSM, however, residual opaque objects cause stripe artifacts, which obscure features of interest and, during functional imaging, modulate fluorescence variations related to neuronal activity. Here, we report how Bessel beams reduce streaking artifacts and produce high-fidelity quantitative data demonstrating a fivefold increase in sensitivity to calcium transients and a 20-fold increase in accuracy in the detection of activity correlations in functional imaging. Furthermore, using principal component analysis, we show that measurements obtained with Bessel beams are clean enough to reveal in one-shot experiments correlations that can not be averaged over trials after stimuli as is the case when studying spontaneous activity. Our results not only demonstrate the contamination of data by systematic and random errors through conventional Gaussian illumination and but,furthermore, quantify the increase in fidelity of such data when using Bessel beams. PMID- 30294261 TI - Sigma-1 Receptor-Modulated Neuroinflammation in Neurological Diseases. AB - A large body of evidence indicates that sigma-1 receptors (Sig-1R) are important drug targets for a number of neuropsychiatric disorders. Sig-1Rs are enriched in central nervous system (CNS). In addition to neurons, both cerebral microglia and astrocytes express Sig-1Rs. Activation of Sig-1Rs is known to elicit potent neuroprotective effects and promote neuronal survival via multiple mechanisms, including promoting mitochondrial functions, decreasing oxidative stress and regulating neuroimmnological functions. In this review article, we focus on the emerging role of Sig-1Rs in regulating neuroinflammation and discuss the recent advances on the Sig-1R-modulating neuroinflammation in the pathophysiology and therapy of neurodegenerative disorders. PMID- 30294263 TI - A Comparison of Machine Learning Classifiers for Energy-Efficient Implementation of Seizure Detection. AB - The closed-loop application of electrical stimulation via chronically implanted electrodes is a novel approach to stop seizures in patients with focal-onset epilepsy. To this end, an energy efficient seizure detector that can be implemented in an implantable device is of crucial importance. In this study, we first evaluated the performance of two machine learning algorithms (Random Forest classifier and support vector machine (SVM)) by using selected time and frequency domain features with a limited need of computational resources. Performance of the algorithms was further compared to a detection strategy implemented in an existing closed loop neurostimulation device for the treatment of epilepsy. The results show a superior performance of the Random Forest classifier compared to the SVM classifier and the reference approach. Next, we implemented the feature extraction and classification process of the Random Forest classifier on a microcontroller to evaluate the energy efficiency of this seizure detector. In conclusion, the feature set in combination with Random Forest classifier is an energy efficient hardware implementation that shows an improvement of detection sensitivity and specificity compared to the presently available closed-loop intervention in epilepsy while preserving a low detection delay. PMID- 30294264 TI - Precision and False Perceptual Inference. AB - Accurate perceptual inference fundamentally depends upon accurate beliefs about the reliability of sensory data. In this paper, we describe a Bayes optimal and biologically plausible scheme that refines these beliefs through a gradient descent on variational free energy. To illustrate this, we simulate belief updating during visual foraging and show that changes in estimated sensory precision (i.e., confidence in visual data) are highly sensitive to prior beliefs about the contents of a visual scene. In brief, confident prior beliefs induce an increase in estimated precision when consistent with sensory evidence, but a decrease when they conflict. Prior beliefs held with low confidence are rapidly updated to posterior beliefs, determined by sensory data. These induce much smaller changes in beliefs about sensory precision. We argue that pathologies of scene construction may be due to abnormal priors, and show that these can induce a reduction in estimated sensory precision. Having previously associated this precision with cholinergic signaling, we note that several neurodegenerative conditions are associated with visual disturbances and cholinergic deficits; notably, the synucleinopathies. On relating the message passing in our model to the functional anatomy of the ventral visual stream, we find that simulated neuronal loss in temporal lobe regions induces confident, inaccurate, empirical prior beliefs at lower levels in the visual hierarchy. This provides a plausible, if speculative, computational mechanism for the loss of cholinergic signaling and the visual disturbances associated with temporal lobe Lewy body pathology. This may be seen as an illustration of the sorts of hypotheses that may be expressed within this computational framework. PMID- 30294265 TI - When Does Oxytocin Affect Human Memory Encoding? The Role of Social Context and Individual Attachment Style. AB - The neuropeptide oxytocin plays an essential role in regulating social behavior and has been implicated in a variety of human cognitive processes in the social domain, including memory processes. The present study investigates the influence of oxytocin on human memory encoding, taking into account social context and personality, which have previously been neglected as moderators for how oxytocin affects memory encoding. To examine the role of social context of encoding, we employed an established experimental paradigm in which participants perform a word-categorization task in either a joint (social) or individual (non-social) setting. To investigate the role of socially relevant personality factors, participants' adult attachment style (AAS) was assessed. Previous research has identified attachment style as a potent moderator of oxytocin effects in the social-cognitive domain, but here we investigated for the first time its role in memory encoding. Participants were invited in pairs and received either placebo or oxytocin intranasally. Forty-five minutes later, they were instructed to react to different word categories within a list of successively presented words. This task was performed individually in the non-social condition and simultaneously with the partner in the social condition. After a 24-h delay, memory for all words was tested individually in a surprise recognition memory test. Oxytocin effects on memory accuracy depended on participants' AAS. Specifically, oxytocin positively affected memory for participants who scored low on attachment dependence (who find dependence on others uncomfortable), but negatively affected memory for high scorers (who are comfortable depending on others). Oxytocin effects were not moderated by social vs. non-social context at encoding, and we discuss reasons for this outcome. Regardless of encoding condition or personality, oxytocin led to more liberal responding in the recognition memory test, which was also reflected in significantly higher false alarm rates (FARs) and a trend towards higher hit rates (HRs) compared to placebo. Overall, our results are consistent with an interactionist view on oxytocin effects on human cognitive functioning. Future research should further examine how oxytocin affects response biases via previous encoding and the ways in which biological dispositions linked to attachment style affect the process of memory encoding. PMID- 30294267 TI - Out of the Loop, in Your Bubble: Mind Wandering Is Independent From Automation Reliability, but Influences Task Engagement. AB - This study examined the influence of automation reliability on task-unrelated mind wandering (MW) frequency and the impact of MW on task engagement. Automated environment features make it particularly prone to increase MW frequency. Through mechanisms like complacency or agency, automating a task could increase MW frequency for the operator. For safety-critical industries, the lower perception and degraded stimuli processing associated with MW, summarized by the term "decoupling hypothesis," are particularly concerning. Sixteen participants supervised an autopilot avoiding obstacles with two levels of reliability. Each condition lasted 45 min. We recorded thoughts as either pertaining to being focused, task-related MW or task-unrelated MW. We also recorded perceived mental demand, trust regarding the autopilot and oculometric measures. Based on questionnaire results, our protocol succeeded in inducing more mental demand and lower trust when the automation was unreliable. Attentional states were not correlated, nor did it influence trust in the system reliability. On the contrary, mental demand ratings and pupil diameter were lower during both task related and task-unrelated MW, compared to those during the focus attentional state. This shows that perceptual decoupling also affects the engagement of operators in automated environments, which may dramatically lower their ability to supervise automation efficiently. This research informs human-automation designers to consider operator engagement when creating automated systems. PMID- 30294266 TI - Cognitive Fatigue, Sleep and Cortical Activity in Multiple Sclerosis Disease. A Behavioral, Polysomnographic and Functional Near-Infrared Spectroscopy Investigation. AB - Patients with multiple sclerosis (MS) disease frequently experience fatigue as their most debilitating symptom. Fatigue in MS partially refers to a cognitive component, cognitive fatigue (CF), characterized by a faster and stronger than usual development of the subjective feeling of exhaustion that follows sustained cognitive demands. The feeling of CF might result from supplementary task-related brain activity following MS-related demyelination and neurodegeneration. Besides, CF in MS disease might also stem from disrupted sleep. The present study investigated the association between the triggering of CF, task-related brain activity and sleep features. In a counterbalance mixed design, 10 patients with MS and 11 healthy controls were exposed twice for 16 min to a CF-inducing dual working memory updating task (TloadDback) under low or high cognitive demands conditions, counterbalanced. Considering known inter-individual differences and potential cognitive deficits in MS, the maximal cognitive load of the task was individually adapted to each participant's own upper limits. During the experimental sessions, cortical brain activity was measured using near-infrared spectroscopy (NIRS) during the CF-induction task, and in a resting state immediately before and after. Ambulatory polysomnography recordings were obtained on the nights preceding experimental sessions. When cognitive load was individually adapted to their processing capabilities, patients with MS exhibited similar than healthy controls levels of subjectively perceived CF, evolution of performance during the task, and brain activity patterns. Linear mixed models indicate a negative association between oxygenation level changes in the dorsolateral prefrontal cortex (DLPFC) and the triggering of subjective CF in patients with MS only. Longer total sleep time was also associated with higher CF in MS patients. These results suggest that controlling for cognitive load between individuals with and without MS results in a similar task-related development of subjective CF. Besides comparable performance and cortical brain activity between groups, mixed model analyses suggest a possible association between CF, DLPFC activity and sleep duration in MS disease. PMID- 30294268 TI - A Computational Model of Deep-Brain Stimulation for Acquired Dystonia in Children. AB - The mechanism by which deep brain stimulation (DBS) improves dystonia is not understood, partly heterogeneity of the underlying disorders leads to differing effects of stimulation in different locations. Similarity between the effects of DBS and the effects of lesions has led to biophysical models of blockade or reduced transmission of involuntary activity in individual cells in the pathways responsible for dystonia. Here, we expand these theories by modeling the effect of DBS on populations of neurons. We emphasize the important observation that the DBS signal itself causes surprisingly few side effects and does not normally appear in the electromyographic signal. We hypothesize that, at the population level, massively synchronous rhythmic firing caused by DBS is only poorly transmitted through downstream populations. However, the high frequency of stimulation overwhelms incoming dystonic activity, thereby substituting an ineffectively transmitted exogenous signal for the endogenous abnormal signal. Changes in sensitivity can occur not only at the site of stimulation, but also at downstream sites due to synaptic and homeostatic plasticity mechanisms. The mechanism is predicted to depend strongly on the stimulation frequency. We provide preliminary data from simultaneous multichannel recordings in basal ganglia and thalamus in children with secondary dystonia. We also provide illustrative simulations of the effect of stimulation frequency on the transmission of the DBS pulses through sequential populations of neurons in the dystonia pathway. Our experimental results and model provide a new hypothesis and computational framework consistent with the clinical features of DBS in childhood acquired dystonia. PMID- 30294269 TI - Accurate Reconstruction of Image Stimuli From Human Functional Magnetic Resonance Imaging Based on the Decoding Model With Capsule Network Architecture. AB - In neuroscience, all kinds of computation models were designed to answer the open question of how sensory stimuli are encoded by neurons and conversely, how sensory stimuli can be decoded from neuronal activities. Especially, functional Magnetic Resonance Imaging (fMRI) studies have made many great achievements with the rapid development of deep network computation. However, comparing with the goal of decoding orientation, position and object category from human fMRI in visual cortex, accurate reconstruction of image stimuli is a still challenging work. Current prevailing methods were composed of two independent steps, (1) decoding intermediate features from human fMRI and (2) reconstruction using the decoded intermediate features. The new concept of 'capsule' and 'capsule' based neural network were proposed recently. The 'capsule' represented a kind of structure containing a group of neurons to perform better feature representation. Especially, the high-level capsule's features in the capsule network (CapsNet) contains various features of image stimuli such as semantic class, orientation, location, scale and so on, and these features can better represent the processed information inherited in the fMRI data collected in visual cortex. In this paper, a novel CapsNet architecture based visual reconstruction (CNAVR) computation model is developed to reconstruct image stimuli from human fMRI. The CNAVR is composed of linear encoding computation from capsule's features to fMRI data and inverse reconstruction computation. In the first part, we trained the CapsNet model to obtain the non-linear mappings from images to high-level capsule's features, and from high-level capsule's features to images again in an end-to-end manner. In the second part, we trained the non-linear mapping from fMRI data of selected voxels to high-level capsule's features. For a new image stimulus, we can use the method to predict the corresponding high-level capsule's features using fMRI data, and reconstruct image stimuli with the trained reconstruction part in the CapsNet. We evaluated the proposed CNAVR method on the open dataset of handwritten digital images, and exceeded about 10% than the accuracy of all existing state-of-the-art methods on the structural similarity index (SSIM). In addition, we explained the selected voxels in specific interpretable image features to prove the effectivity and generalization of the CNAVR method. PMID- 30294270 TI - Isoliquiritigenin Inhibits Cigarette Smoke-Induced COPD by Attenuating Inflammation and Oxidative Stress via the Regulation of the Nrf2 and NF-kappaB Signaling Pathways. AB - Chronic obstructive pulmonary disease (COPD) is the major leading cause of disease with high-mortality worldwide. Cigarette smoke (CS) is a major factor for COPD. CS causes chronic inflammation and oxidative stress, which contributes to lung dysfunction in COPD. Isoliquiritigenin (ILG), a natural flavonoid derived from the root of liquorice, has been reported to possess antiinflammatory and antioxidant activity. In the present study, we tested the mechanism and protective effects of ILG on CS-induced COPD. Mice were exposed to CS for 2 h twice a day for 4 weeks. ILG was given orally 1 h before CS exposure twice a day for 4 weeks. The bronchial alveolar lavage fluid was collected to test the levels of inflammatory cytokines and the number of inflammatory cells. The lung tissues were obtained to evaluate the pathological changes, lung edema, myeloperoxidase (MPO) activity, malondialdehyde (MDA) level, as well as the expression of the nuclear factor-erythroid 2 (Nrf2) and nuclear factor kappaB (NF-kappaB) signaling pathways. The results showed that ILG reduced the infiltration of inflammatory cells and the production of inflammatory cytokines. ILG also reversed CS-induced lung pathological injuries, wet/dry ratio, MPO activity, and MDA level. Further research also showed that ILG dose-dependently up-regulated the expression of Nrf2 and down-regulated the expression of NF-kappaB signaling pathways induced by CS. In conclusion, ILG protected against CS-induced COPD by inhibiting inflammatory and oxidative stress via the regulation of the Nrf2 and NF-kappaB signaling pathways. PMID- 30294271 TI - Identification of Antioxidant Proteins With Deep Learning From Sequence Information. AB - Antioxidant proteins have been found closely linked to disease control for its ability to eliminate excess free radicals. Because of its medicinal value, the study of identifying antioxidant proteins is on the upsurge. Many machine learning classifiers have performed poorly owing to the nonlinear and unbalanced nature of biological data. Recently, deep learning techniques showed advantages over many state-of-the-art machine learning methods in various fields. In this study, a deep learning based classifier was proposed to identify antioxidant proteins based on mixed g-gap dipeptide composition feature vector. The classifier employed deep autoencoder to extract nonlinear representation from raw input. The t-Distributed Stochastic Neighbor Embedding (t-SNE) was used for dimensionality reduction. Support vector machine was finally performed for classification. The classifier achieved F 1 score of 0.8842 and MCC of 0.7409 in 10-fold cross validation. Experimental results show that our proposed method outperformed the traditional machine learning methods and could be a promising tool for antioxidant protein identification. For the convenience of others' scientific research, we have developed a user-friendly web server called IDAod for antioxidant protein identification, which can be accessed freely at http://bigroup.uestc.edu.cn/IDAod/. PMID- 30294273 TI - The Pathways for Layered Double Hydroxide Nanoparticles to Enhance Antigen (Cross)-Presentation on Immune Cells as Adjuvants for Protein Vaccines. AB - Nanoparticles (NPs) are intensively investigated as adjuvants in new generation vaccines, while how these NPs promote the immune responses has not been well understood. In this research, we have tried to elucidate the possible pathways for layered double hydroxide (LDH) NPs to provoke immune responses. As previously reported, LDH NPs efficiently deliver antigens to antigen presenting cells (APCs). In this research, we have found that these internalized LDH NPs are not released by these APCs within 8 h. We have for the first time found that macrophage cells exchange the internalized LDH NPs with other surrounding ones, which may promote immune responses in an additional way. Moreover, the internalized LDH-antigen NPs significantly facilitate the maturation of immature DCs and enhance cross-presentation of epitope/MHC class I complexes on the DC surface. This research would help understand the NP adjuvant mechanism and further assist the design of new specific NPs as more efficient nano-adjuvants.

PMID- 30294275 TI - Comparative Price Analysis of Biological Products for Treatment of Rheumatoid Arthritis. AB - Biological products for treatment of rheumatoid arthritis usually are cost effective for healthcare systems in Europe, but they are huge financial burden due to the high number of patients and the significant budget impact. The expected saving from introduction on the market of biosimilars are significant and are linked to better access and affordability. The aim of this study was to conduct comparative price analysis of biological products for rheumatoid arthritis therapy among seventeen EU countries. The point of view is that of the Bulgarian pricing and reimbursement system and the chosen countries are those from external reference basket for prices comparison at manufacturing level. All authorized biological products by EMA with therapeutic indication rheumatoid arthritis were selected. The access for treatment is evaluated as the availability of the product on the market and the prices level. We assessed the availability of all trade names in the price lists of the observed countries. The prices data was obtained from the official web pages of the responsible institutions up to date December 2017. The results show that four out of all six INNs have authorized biosimilars in EMA. Despite its earlier authorization biosimilar adalimumab is not present in any of the price lists of countries. From all eighteen countries only in Lithuania and Estonia there were no published prices of any of the selected medicinal products. Countries with higher number of biosimilar prices are Spain and France. Differences in manufacturers' prices of reference biological products in selected countries in comparison with the lowest manufacturer price are higher with 22 to 69% while the retail prices between 62 and 95%. Differences are mostly notable for rituximab, and less notable for tocilizumab. Manufacturers' and retail prices of biosimilar products were established only for three INNs (etanercept, rituximab, and infliximab). Manufacturers' prices differ between 26 and 75%, while retail prices differ between 40 and 92% for biosimilars. Comparison of the differences between manufacturer prices of reference biological product and biosimilars shows 36% difference for etanercept, 39% for rituximab, and 31% for infliximab, while at retail level the differences are 11, 86, and 143%, respectively. The limitation of the study is that the prices are the official ones without discounts due to confidentiality and the real prices may be lower. The second limitation is that the methodology for pricing differs in the countries and this could also influence the prices on both levels (manufacturer and retail). Introduction of biosimilars on the national markets led to significant decrease in reimbursed prices paid by public funds and thus might benefit the patients' access to biological therapy. The decrease of prices after biosimilars entrance on the market is not as notable as for commodity generics. PMID- 30294272 TI - Prognostic Factors for Checkpoint Inhibitor Based Immunotherapy: An Update With New Evidences. AB - Checkpoint inhibitor (CPI) based immunotherapy (i.e., anit-CTLA-4/PD-1/PD-L1 antibodies) can effectively prolong overall survival of patients across several cancer types at the advanced stage. However, only part of patients experience objective responses from such treatments, illustrating large individual differences in terms of both efficacy and adverse drug reactions. Through the observation on a series of CPI based clinical trials in independent patient cohorts, associations of multiple clinical and molecular characteristics with CPI response rate have been determined, including microenvironment, genomic alterations of the cancer cells, and even gut microbiota. A broad interest has been drawn to the question whether and how these prognostic factors can be used as biomarkers for optimal usage of CPIs in precision immunotherapy. Therefore, we reviewed the candidate prognostic factors identified by multiple trials and the experimental investigations, especially those reported in the recent 2 years, and described the possibilities and problems of them in routine clinical usage of cancer treatment as biomarkers. PMID- 30294276 TI - Common Traits Spark the Mitophagy/Xenophagy Interplay. AB - Selective autophagy contributes to the wellbeing of eukaryotic cells by recycling cellular components, disposing damaged organelles, and removing pathogens, amongst others. Both the quality control process of selective mitochondrial autophagy (Mitophagy) and the defensive process of intracellular pathogen engulfment (Xenophagy) are facilitated via protein assemblies which have shared molecules, a prime example being the Tank-Binding Kinase 1 (TBK1). TBK1 plays a central role in the immunity response driven by Xenophagy and was recently shown to be an amplifying mechanism in Mitophagy, bring to attention the potential cross talk between the two processes. Here we draw parallels between Xenophagy and Mitophagy, speculating on the inhibitory mechanisms of specific proteins (e.g., the 18 kDa protein TSPO), how the preferential sequestering toward one of the two pathways may undermine the other, and in this way impair cellular response to pathogens and cellular immunity. We believe that an in depth understanding of the commonalities may present an opportunity to design novel therapeutic strategies targeted at both the autonomous and non-autonomous processes of selective autophagy. PMID- 30294277 TI - Characterization of Simultaneous Pressure Waves as Biomarkers for Colonic Motility Assessed by High-Resolution Colonic Manometry. AB - Simultaneous pressure waves (SPWs) in manometry recordings of the human colon have been associated with gas expulsion. Our hypothesis was that the SPW might be a critical component of most colonic motor functions, and hence might act as a biomarker for healthy colon motility. To that end, we performed high-resolution colonic manometry (HRCM), for the first time using an 84-sensor (1 cm spaced) water-perfused catheter, in 17 healthy volunteers. Intraluminal pressure patterns were recorded during baseline, proximal and rectal balloon distention, after a meal and following proximal and rectal luminal bisacodyl administration. Quantification was performed using software, based on Image J, developed during this study. Gas expulsion was always associated with SPWs, furthermore, SPWs were associated with water or balloon expulsion. SPWs were prominently emerging at the termination of proximal high amplitude propagating pressure waves (HAPWs); we termed this motor pattern HAPW-SPWs; hence, SPWs were often not a pan-colonic event. SPWs and HAPW-SPWs were observed at baseline with SPW amplitudes of 12.0 +/- 8.5 mmHg and 20.2 +/- 7.2 mmHg respectively. The SPW occurrence and amplitude significantly increased in response to meal, balloon distention and luminal bisacodyl, associated with 50.3% anal sphincter relaxation at baseline, which significantly increased to 59.0% after a meal, and 69.1% after bisacodyl. Often, full relaxation was achieved. The SPWs associated with gas expulsion had a significantly higher amplitude compared to SPWs without gas expulsion. SPWs could be seen to consist of clusters of high frequency pressure waves, likely associated with a cluster of fast propagating, circular muscle contractions. SPWs were occasionally observed in a highly rhythmic pattern at 1.8 +/- 1.2 cycles/min. Unlike HAPWs, the SPWs did not obliterate haustral boundaries thereby explaining how gas can be expelled while solid content can remain restrained by the haustral boundaries. In conclusion, the SPW may become a biomarker for normal gas transit, the gastrocolonic reflex and extrinsic neural reflexes. The SPW assessment reveals coordination of activities in the colon, rectum and anal sphincters. SPWs may become of diagnostic value in patients with colonic dysmotility. PMID- 30294278 TI - Cell-Free Circulating Nucleic Acids as Early Biomarkers for NAFLD and NAFLD Associated Disorders. AB - Non-alcoholic fatty liver disease (NAFLD) is the worldwide most common cause of chronic liver pathology, which prevalence strongly correlates with the increasing incidence of diabetes, obesity and metabolic syndrome in the general population. Simple steatosis, the earliest NAFLD stage, usually remains asymptomatic, and appropriate changes in the lifestyle, as well as the diet, can reverse the affected liver into the healthy state. The potential of simple steatosis to progress into severe fibrotic stages and to facilitate carcinogenesis necessitates timely NAFLD detection and risk stratification in community-based healthcare settings. Since their initial discovery a decade ago, extracellular circulating miRNAs have been found in all human biological fluids including blood and shown to hold great promises as non-invasive biomarkers. Normally, intracellular miRNAs participate in the regulation of gene expression, but once released by dying/dead cells they remain highly stable in the extracellular environment for prolonged periods. Therefore, circulating miRNA profiles can reflect the ongoing pathogenic processes in body's tissues and organs, and enable highly sensitive non-invasive diagnosis of multiple disorders. A non-urgent character of the NAFLD-related decision-making justifies the use of chronic liver diseases as an excellent test case for examining the practical utility of circulating miRNAs as biomarkers for longitudinal monitoring of human health. In this review, we summarize the state-of-the-art in the field of early diagnosis of NAFLD using circulating blood miRNAs, and stress the necessity of additional experimental validation of their diagnostic potential. We further emphasize on the potential diagnostics promises of other cell-free RNA species found in human biological fluids. PMID- 30294280 TI - Investigation of the Syncytial Nature of Detrusor Smooth Muscle as a Determinant of Action Potential Shape. AB - Unlike most excitable cells, certain syncytial smooth muscle cells are known to exhibit spontaneous action potentials of varying shapes and sizes. These differences in shape are observed even in electrophysiological recordings obtained from a single cell. The origin and physiological relevance of this phenomenon are currently unclear. The study presented here aims to test the hypothesis that the syncytial nature of the detrusor smooth muscle tissue contributes to the variations in the action potential profile by influencing the superposition of the passive and active signals. Data extracted from experimental recordings have been compared with those obtained through simulations. The feature correlation studies on action potentials obtained from the experimental recordings suggest the underlying presence of passive signals, called spontaneous excitatory junction potentials (sEJPs). Through simulations, we are able to demonstrate that the syncytial organization of the cells, and the variable superposition of the sEJPs with the "native action potential", contribute to the diversity in the action potential profiles exhibited. It could also be inferred that the fraction of the propagated action potentials is very low in the detrusor. It is proposed that objective measurements of spontaneous action potential profiles can lead to a better understanding of bladder physiology and pathology. PMID- 30294279 TI - Pathogenesis and Treatment Options of Cancer Related Anemia: Perspective for a Targeted Mechanism-Based Approach. AB - Cancer-related anemia (CRA) is a common sign occurring in more than 30% of cancer patients at diagnosis before the initiation of antineoplastic therapy. CRA has a relevant influence on survival, disease progression, treatment efficacy, and the patients' quality of life. It is more often detected in patients with advanced stage disease, where it represents a specific symptom of the neoplastic disease, as a consequence of chronic inflammation. In fact, CRA is characterized by biological and hematologic features that resemble those described in anemia associated to chronic inflammatory disease. Proinflammatory cytokine, mainly IL 6, which are released by both tumor and immune cells, play a pivotal action in CRA etiopathogenesis: they promote alterations in erythroid progenitor proliferation, erythropoietin (EPO) production, survival of circulating erythrocytes, iron balance, redox status, and energy metabolism, all of which can lead to anemia. The discovery of hepcidin allowed a greater knowledge of the relationships between immune cells, iron metabolism, and anemia in chronic inflammatory diseases. Additionally, chronic inflammation influences a compromised nutritional status, which in turn might induce or contribute to CRA. In the present review we examine the multifactorial pathogenesis of CRA discussing the main and novel mechanisms by which immune, nutritional, and metabolic components affect its onset and severity. Moreover, we analyze the status of the art and the perspective for the treatment of CRA. Notably, despite the high incidence and clinical relevance of CRA, controlled clinical studies testing the most appropriate treatment for CRA are scarce, and its management in clinical practice remains challenging. The present review may be useful to indicate the development of an effective approach based on a detailed assessment of all factors potentially involved in the pathogenesis of CRA. This mechanism based approach is essential for clinicians to plan a safe, targeted, and successful therapy, thereby promoting a relevant amelioration of patients' quality of life. PMID- 30294281 TI - Validation and Opportunities of Electrocardiographic Imaging: From Technical Achievements to Clinical Applications. AB - Electrocardiographic imaging (ECGI) reconstructs the electrical activity of the heart from a dense array of body-surface electrocardiograms and a patient specific heart-torso geometry. Depending on how it is formulated, ECGI allows the reconstruction of the activation and recovery sequence of the heart, the origin of premature beats or tachycardia, the anchors/hotspots of re-entrant arrhythmias and other electrophysiological quantities of interest. Importantly, these quantities are directly and non-invasively reconstructed in a digitized model of the patient's three-dimensional heart, which has led to clinical interest in ECGI's ability to personalize diagnosis and guide therapy. Despite considerable development over the last decades, validation of ECGI is challenging. Firstly, results depend considerably on implementation choices, which are necessary to deal with ECGI's ill-posed character. Secondly, it is challenging to obtain (invasive) ground truth data of high quality. In this review, we discuss the current status of ECGI validation as well as the major challenges remaining for complete adoption of ECGI in clinical practice. Specifically, showing clinical benefit is essential for the adoption of ECGI. Such benefit may lie in patient outcome improvement, workflow improvement, or cost reduction. Future studies should focus on these aspects to achieve broad adoption of ECGI, but only after the technical challenges have been solved for that specific application/pathology. We propose 'best' practices for technical validation and highlight collaborative efforts recently organized in this field. Continued interaction between engineers, basic scientists, and physicians remains essential to find a hybrid between technical achievements, pathological mechanisms insights, and clinical benefit, to evolve this powerful technique toward a useful role in clinical practice. PMID- 30294284 TI - One Year of Yoga Training Alters Ghrelin Axis in Centrally Obese Adults With Metabolic Syndrome. AB - Introduction: Metabolic syndrome (MetS) is a multiplex cardiometabolic manifestation associated with type 2 diabetes mellitus and cardiovascular diseases. Yoga training has been shown to alleviate MetS. Recently, circulatory ghrelin profile was demonstrated to be associated with MetS. This study examined the effects of 1 year of yoga training on beta-cell function and insulin resistance, and the involvement of metabolic peptides, including unacylated ghrelin (UnAG), acylated ghrelin (AG), obestatin, growth hormone (GH), and insulin, in the beneficial effects of yoga training in centrally obese adults with MetS. Methods: This was a follow up study, in which data of risk factors of MetS, physical performance tests [resting heart rate (HR), chair stand test (CS), chair sit and reach test (CSR), back scratch test (BS), and single leg stand tests (SLS)] and serum samples of 79 centrally obese MetS subjects aged 58 +/- 8 years (39 subjects received 1-year yoga training and 40 subjects received no training) were retrieved for analyses. beta-cell function and insulin resistance were examined by Homeostasis Model Assessment (HOMA). Circulating levels of UnAG, AG, obestatin, GH, and insulin were determined by enzyme-linked immunosorbent assay using fasting serum samples. Generalized estimating equation analysis and Mann-Whitney U-test were used to detect statistically significant differences between groups. Results: Waist circumference (WC) was significantly decreased after yoga intervention (control: +2%; yoga: -4%). Significant improvements in HR (control: +2%; yoga: -5%), CS (control: -1%; yoga: +24%), CSR left (control: worsen by 0.90 cm; yoga: improved by 4.21 cm), CSR right (control: worsen by 0.75 cm; yoga: improved by 4.28 cm), right side of BS (control: improved by 0.19 cm; yoga: improved by 4.31 cm), SLS left (control: -10%; yoga: +86%), and SLS right (control: -6%; yoga: +47%) were observed after 1-year yoga training. No significant difference was found between the two groups in insulin, HOMA indices, and disposition index. Yoga training significantly increased circulating GH (control: -3%; yoga: +22%), total circulating ghrelin (control: -26%; yoga: +13%), and UnAG (control: -27%; yoga: +14%), whereas decreased AG (control: -7%; yoga: -33%) and obestatin (control: +24%; yoga: -29%). Conclusion: One-year of yoga training modulated total ghrelin, UnAG, AG, obestatin, and GH while exerting beneficial effects on physical functions and central obesity in adults with MetS. The beneficial effects of yoga may be associated with the alteration of ghrelin gene product and GH. PMID- 30294283 TI - RBPs Play Important Roles in Vascular Endothelial Dysfunction Under Diabetic Conditions. AB - Diabetes is one of the major health care problems worldwide leading to huge suffering and burden to patients and society. Diabetes is also considered as a cardiovascular disorder because of the correlation between diabetes and an increased incidence of cardiovascular disease. Vascular endothelial cell dysfunction is a major mediator of diabetic vascular complications. It has been established that diabetes contributes to significant alteration of the gene expression profile of vascular endothelial cells. Post-transcriptional regulation by RNA binding proteins (RBPs) plays an important role in the alteration of gene expression profile under diabetic conditions. The review focuses on the roles and mechanisms of critical RBPs toward diabetic vascular endothelial dysfunction. Deeper understanding of the post- transcriptional regulation by RBPs could lead to new therapeutic strategies against diabetic manifestation in the future. PMID- 30294285 TI - Current Perspectives on Role of MSC in Renal Pathophysiology. AB - In the course of the development and worsening of kidney disease, the treatments available are expensive and may cause adverse effects such as immune rejection, inadequate renal resources, or post-operative complications. Therefore, there is an urgent to develop more effective treatments. The advent of mesenchymal stem cells (MSCs) represents a new direction in this context. The current use of MSCs for the treatment of kidney disease has mostly involved experimental studies on animals and only a few clinical trials have been conducted. This review focused on the mechanisms of MSC involvement from different sources in the improvement of renal pathophysiology in recent years. These mechanisms include homing to damaged kidney tissue, and differentiating into or fusing with the innate cells of the kidney. The paracrine or endocrine action through secreting protective cytokines and/or releasing microvesicle from MSCs also plays a critical role in amelioration of kidney disease. With modern engineering technology like microRNA delivery and a combinational therapy approach such as reduction of renal fibrosis in obstructive nephropathy with MSCs and serelaxin, MSC may make great contribution to the improvement of renal pathophysiology. However, the therapeutic effects of MSC are still controversial and several problems remain unsolved. While it is too early to state that MSCs are useful for the treatment of renal diseases in clinic, it is thought that solutions to the existing problems will enable effective modulation of the biological characteristics of MSCs, thereby providing new and effective approaches for the treatment of renal diseases. PMID- 30294282 TI - Membrane Proteins Mediating Reception and Transduction in Chemosensory Neurons in Mosquitoes. AB - Mosquitoes use chemical cues to modulate important behaviors such as feeding, mating, and egg laying. The primary chemosensory organs comprising the paired antennae, maxillary palps and labial palps are adorned with porous sensilla that house primary sensory neurons. Dendrites of these neurons provide an interface between the chemical environment and higher order neuronal processing. Diverse proteins located on outer membranes interact with chemicals, ions, and soluble proteins outside the cell and within the lumen of sensilla. Here, we review the repertoire of chemosensory receptors and other membrane proteins involved in transduction and discuss the outlook for their functional characterization. We also provide a brief overview of select ion channels, their role in mammalian taste, and potential involvement in mosquito taste. These chemosensory proteins represent targets for the disruption of harmful biting behavior and disease transmission by mosquito vectors. PMID- 30294286 TI - Dose Reduction/Discontinuation of Antipsychotic Drugs in Psychosis; Effect on Cognition and Functional Outcomes. AB - Backgrounds: There is a debate regarding the optimal timing of discontinuation of antipsychotic drugs in patients with first episode psychosis (FEP) or schizophrenia. We aimed to provide a review of the literature on which strategy (medication maintenance vs. dose reduction/discontinuation) is more likely to maximize outcomes, such as cognition and social function. Methods: Using PubMed, the Cochrane Library and systematic reviews, articles published between 2007 and 2018 were reviewed, which investigated the effect of dose reduction/discontinuation vs. maintenance treatment on measures of cognition and/or social function in FEP and schizophrenia. Results: Six studies were identified; 2 studies reported on cognition while 4 studies concern social function. All studies except one reported that improvement of functional outcomes in remitted patients with FEP or schizophrenia allocated to a dose reduction/discontinuation arm was equal to or better than that in patients for whom medication doses were maintained. One trial of social function with a 1-year follow-up period found a greater improvement in the medication maintenance group, while no group difference was observed with 3-year and 10-year follow-up periods. On the other hand, a 7-year follow-up study found a superiority for the dose reduction/discontinuation regimen in terms of social outcome. Two studies on cognition with a short follow-up period reported a greater improvement for the dose reduction/discontinuation group. Conclusions: Information on cognition and social function has been relatively sparse. These measures of functional outcome should be considered in deciding which strategy of antipsychotic treatments is beneficial in individual cases with FEP or schizophrenia. PMID- 30294287 TI - Creative Arts-Based Therapies for Stroke Survivors: A Qualitative Systematic Review. AB - Background: Stroke is a life-threating cerebrovascular disease. Without proper and immediate treatment, it can cause long-term disabilities and even death. While current rehabilitation focuses on functional needs, it does not fully address the psychosocial issues. Creative arts-based therapies, however, may have the potential to be of assistance. Methods: A systematic review was conducted to synthesize the qualitative findings of the stroke survivors' positive and negative experiences in participating in creative arts-based therapies. A systematic literature search was conducted across diverse databases. A thematic synthesis was adopted to analyze the results from different qualitative studies and mix-method studies. Results: Among the 367 studies extracted from various databases, 11 studies met the inclusion criteria and were of acceptable quality. The following five analytical themes were identified: functional restoration, psychological support, social engagement, spiritual experience, and short-comings and barriers. Conclusion: Creative arts-based therapies have demonstrated their strengths in addressing psychosocial needs for stroke survivors. Different art modalities are perceived to be useful in achieving different therapeutic goals. Therapies based on a single art modality or combined modalities have different specialties and characteristics. Further research is needed to demonstrate the differential benefits or special advantages of using single or multiple art modalities as well as having qualified therapists in creative arts-based therapies. PMID- 30294288 TI - Microexpressions Are Not the Best Way to Catch a Liar. PMID- 30294289 TI - Perpetuating Inequality: Junior Women Do Not See Queen Bee Behavior as Negative but Are Nonetheless Negatively Affected by It. AB - Previous research has revealed that women may attempt to avoid negative gender stereotypes in organizations through self-group distancing, or "queen bee", behaviors: emphasizing masculine qualities, distancing themselves from other women, and legitimizing organizational inequality. Factors that increase self group distancing have been identified (e.g., existing discrimination and low group identification), but it is unknown how self-group distancing by an ingroup leader is perceived by and affects subordinates of the negatively stereotyped group. In the current study, female participants received ambiguous negative feedback from a male versus female leader displaying queen bee-type versus neutral behavior. As expected, a male leader displaying queen bee-type behavior was seen as having less positive intent than a male leader displaying neutral behavior, which in turn increased how sexist he was perceived to be. A female leader displaying queen bee (vs. neutral) behavior was not seen as having less positive intent, which thus did not indirectly influence perceived sexism. Behavior of both male and female leaders did affect junior women: participants exposed to a leader displaying queen bee-type behavior reported more anger, sadness, and anxiety than participants exposed to a leader displaying neutral behavior. These data provide further evidence that simply adding more women or minorities in key senior positions is insufficient to change inequality if bias in the organization is not tackled. Specifically, exposure to gender inequality can steer female leaders to endorse-rather than change-stereotypes about women, and this behavior is particularly consequential because it (a) might not be recognized as bias and (b) exerts negative effects. PMID- 30294290 TI - Context-Sensitivity and Individual Differences in the Derivation of Scalar Implicature. AB - The derivation of scalar implicatures for the quantifier some has been widely studied to investigate the computation of pragmatically enriched meanings. For example, the sentence "I found some books" carries the semantic interpretation that at least one book was found, but its interpretation is often enriched to include the implicature that not all the books were found. The implicature is argued to be more likely to arise when it is relevant for addressing a question under discussion (QUD) in the context, e.g., when "I found some books" is uttered in response to "Did you find all the books?" as opposed to "Did you find any books?". However, most experimental studies have not examined the influence of context on some, instead testing some sentences in isolation. Moreover, no study to our knowledge has examined individual differences in the ability to utilize context in interpreting some, whereas individual variation in deriving implicatures for some sentences in isolation is widely attested, with alternative proposals attributing this variation to individual differences in cognitive resources (e.g., working memory) or personality-based pragmatic abilities (e.g., as assessed by the Autism-Spectrum Quotient). The current study examined how context influences the interpretation of some in a story-sentence matching task, where participants rated some statements ("I cut some steaks") uttered by one character, in response to another character's question (QUD) that established the implicature as relevant ("Did you cut all the steaks?") or irrelevant ("Did you cut any steaks?"). We also examined to what extent individuals' sensitivity to QUD is modulated by individual differences via a battery of measures assessing cognitive resources, personality-based pragmatic abilities, and language abilities (which have been argued to modulate comprehension in other domains). Our results demonstrate that QUD affects the interpretation of some, and reveal that individual differences in sensitivity to QUD are modulated by both cognitive resources and personality-based pragmatic abilities. While previous studies have argued alternatively for cognitive resources or personality-based pragmatic abilities as important for deriving implicatures for some in isolation, we argue that arriving at a context-sensitive interpretation for some depends on both cognitive and personality-based properties of the individual. PMID- 30294291 TI - A Developmental Perspective on the Origins of Morality in Infancy and Early Childhood. AB - Key constituents of morality emerge during the first 4 years of life. Recent research with infants and toddlers holds a promise to explain the origins of human morality. This article takes a constructivist approach to the acquisition of morality, and makes three main proposals. First, research on moral development needs an explicit definition of morality. Definitions are crucial for scholarly communication and for settling empirical questions. Second, researchers would benefit from eschewing the dichotomy between innate and learned explanations of morality. Based on work on developmental biology, we propose that all developmental transitions involve both genetic and environmental factors. Third, attention is needed to developmental changes, alongside continuities, in the development of morality from infancy through childhood. Although infants and toddlers show behaviors that resemble the morally relevant behaviors of older children and adults, they do not judge acts as morally right or wrong until later in childhood. We illustrate these points by discussing the development of two phenomena central to morality: Orientations toward helping others and developing concepts of social equality. We assert that a constructivist approach will help to bridge research on infants and toddlers with research on moral developmental later in childhood and into adulthood. PMID- 30294292 TI - Spousal Support for Patients With Rheumatoid Arthritis: Getting the Wrong Kind Is a Pain. AB - Research indicates that perceived support availability is beneficial, with support available from the spouse particularly important for well-being. However, actual support mobilization has shown mixed associations with recipient well being. The primary goal of the present study was to go beyond examining the effects of global perceptions of support on recipient outcomes. Instead, we examined the effects of several specific types of support that have been found to be important in the clinical literature. In this study, we followed both members of couples in which one partner was diagnosed with rheumatoid arthritis. Patients provided reports on pain for both mornings and evenings across 1 week. Both partners also reported esteem, solicitous, and negative support mobilization received by the patient. We found that patient pain tended to increase across the day following increases in patient reports of negative support receipt and partner reports of solicitous support provision. We also found that patient pain tended to decrease across the day when partners reported increased levels of esteem support provision. Reverse causation analyses indicated higher levels of patient pain may lead partners to increase solicitous support mobilization to the patient. Findings underscore the importance of examining both partners' reports of support within a dyadic coping framework. They further suggest that not all forms of support are equally beneficial, calling for a finer grained assessment of specific support transactions. PMID- 30294293 TI - Role of the Cingulate Cortex in Dyskinesias-Reduced-Self-Awareness: An fMRI Study on Parkinson's Disease Patients. AB - Objectives: The detection of dyskinesias-reduced-self-awareness (DRSA), in Parkinson's disease (PD), was previously associated to executive and metacognitive deficits mainly due to dopaminergic overstimulation of mesocorticolimbic circuits. Response-inhibition dysfunction is often observed in PD. Apart from being engaged in response-inhibition tasks, the anterior cingulate cortex (ACC), is part of a functional system based on self-awareness and engaged across cognitive, affective and behavioural contexts. The purpose of the study was to examine the relationship between response-inhibition disabilities and DRSA using whole-brain event-related functional magnetic resonance imaging (fMRI), over the course of a specific executive task. Methods: Twenty-seven cognitively preserved idiopathic PD patients - presenting motor fluctuations and dyskinesias were studied. They underwent a neurological and neuropsychological evaluation. The presence of DRSA was assessed using the Dyskinesias Subtracted-Index (DS-I). Cingulate functionality was evaluated with fMRI, while patients performed an ACC sensitive GO-NoGO task. Association between blood oxygenation level dependent response over the whole-brain during the response-inhibition task and DS-I scores was investigated by regression analysis. Results: The presence of DRSA was associated with reduced functional recruitment in the bilateral ACC, bilateral anterior insular cortex and right dorsolateral prefrontal cortex (pFWE <0.05). Moreover, DS-I scores significantly correlated with percent errors on the NoGO condition (r = 0.491, pFWE = 0.009). Discussion: These preliminary findings add evidence to the relevant role of executive dysfunctions in DRSA pathogenesis beyond the effects of chronic dopaminergic treatment, with a key leading role played by ACC as part of a functionally impaired response-inhibition network. Imaging biomarkers for DRSA are important to be studied, especially when the neuropsychological assessment seems to be normal. PMID- 30294294 TI - Single Dose of the Attention Training Technique Increases Resting Alpha and Beta Oscillations in Frontoparietal Brain Networks: A Randomized Controlled Comparison. AB - The Attention Training Technique (ATT) was developed with the aim of reducing self-focused attention and increasing executive control as part of metacognitive therapy. So far there is a paucity of data on the neurophysiological effects of ATT. In the present study we tested for specific effects to determine if attention control components of ATT elicit a specific signature that is different from passive listening. Thirty-six healthy volunteers were randomized to an active (follow instructions) or control (ignore instructions) condition. Resting state EEG was recorded for 3 min with eyes open and eyes closed before and after exposure to training, and the power of the theta, alpha, and beta-bands were analyzed in frontal, midline, and posterior electrodes. The active ATT condition enhanced alpha and beta-band activity during eyes-open, and frontal alpha during eyes-closed (p < 0.005). Frontoparietal changes in Alpha were generally accompanied by changes in Beta in the same brain regions of interest. However, these associations were largely significant in the active ATT rather than the control condition. No between-group differences were observed in the Theta-band. These results suggest a single dose of attention training increases alpha and beta-oscillations in frontoparietal networks. These networks are associated with top-down attentional or executive control. PMID- 30294295 TI - Different Mechanisms of Two Subtypes of Perforating Artery Infarct in the Middle Cerebral Artery Territory: A High-Resolution Magnetic Resonance Imaging Study. AB - Purpose: Perforating Artery Infarcts (PAIs) can be divided into two subtypes based on their etiologies: branch Atheromatous Disease (BAD) and Lacunar Infarct (LI). Recent studies have shown that while both subtypes can be caused by large artery lesions, the different mechanisms that underlie their development are not clear. This study was designed to use High-Resolution Magnetic Resonance Imaging (HRMRI) to explore the differences that contribute to the occurrence of these two subtypes in large artery lesions in the anterior circulation. Methods: Fifty patients with an acute PAI in the anterior circulation were enrolled (32 BAD and 18 LI patients). The ipsilateral middle cerebral artery (MCA) was scanned with HRMRI to analyze the atherosclerosis plaques. Artery remodeling and plaque characteristics of MCA lesions were compared between the two subtypes. Results: The rate of MCA lesions was significantly higher in BAD and substantially lower in LI (P = 0.033). LAs for the lumen areas in Bad, they were smaller than LI (P < 0.001), Additionally, the plaque area (P = 0.001) and plaque burden (P < 0.001) were superior in the BAD group. Most BAD patients displayed non-positive remodeling, while the great majority of LI patients showed positive remodeling (P < 0.001). Conclusion: In the anterior circulation, a considerable amount of BAD and LI share similarities with atherosclerotic plaques in large arteries. BAD patients mainly showed relatively large and stable atherosclerotic plaques in large arteries, while LI patients mainly exhibited relatively small and unstable atherosclerotic plaques. Clinical Trial Registration: This clinical trial is a retrospective study and therefore does not require registration. PMID- 30294296 TI - The Importance of Inter-Species Variation in Traumatic Brain Injury-Induced Alterations of Microglial-Axonal Interactions. AB - Interactions between microglia and neuronal components are important for normal CNS function. They are also associated with neuroinflammation and many pathological processes and several studies have explored these interactions in terms of phagocytic engulfment. Much progress has also been made in understanding the consequences of chronic neuroinflammatory changes following trauma. However, little is known about acute alterations to these physical non-phagocytic microglial-neuronal interactions following traumatic brain injury (TBI), and particularly to what degree these post-injury interactions may be influenced by the animal species utilized in pre-clinical models of TBI. To investigate these problems, we evaluated the physical interactions between microglia and injured axons acutely (6 h and 1 day) following central fluid percussion injury (cFPI) in both rats and micro pigs. The physical interactions between Iba-1+ microglia and either normal MBP+ myelinated fibers or APP+ injured axonal swellings in the thalamus were assessed following injury or sham via quantitative image analysis of 3D confocal micrographs. The results indicated that the physical interactions between microglia and injured axonal swellings decreased by nearly half in rats 6 h following cFPI but was consistent with sham control at 1 day post-cFPI. This reduction was also observed in non-injured intact fibers at both timepoints following TBI in the rat. Microglial process interactions with injured axons in the micro pig, however, increased nearly 2-fold compared to interactions with intact axonal segments 1 day post-cFPI. This study shows that the species utilized for in vivo pre-clinical studies influences the manner in which microglial-axonal interactions change following TBI. These species differences can be leveraged to further our understanding of the mechanisms involved in microglial process convergence and how these neuro-immune interactions alter the progression of axonal injury following TBI. PMID- 30294297 TI - Effects of Dehydration on Brain Perfusion and Infarct Core After Acute Middle Cerebral Artery Occlusion in Rats: Evidence From High-Field Magnetic Resonance Imaging. AB - Background: Dehydration is common among ischemic stroke patients and is associated with early neurological deterioration and poor outcome. This study aimed to test the hypothesis that dehydration status is associated with decreased cerebral perfusion and aggravation of ischemic brain injury. Methods: Diffusion weighted imaging and arterial spin labeling perfusion MR imaging were performed on rats with middle cerebral artery occlusion (MCAO) by using a 9.4T MR imaging scanner to measure the volume of infarction and relative cerebral blood flow (rCBF) after infarction. Twenty-five rats were assigned to either a dehydration group or normal hydration group, and dehydration status was achieved by water deprivation for 48 h prior to MCAO. Results: The volume of the infarction was significantly larger for the dehydration group at the 4th h after MCAO (p = 0.040). The progression in the infarct volume between the 1st and 4th h was also larger in the dehydration group (p = 0.021). The average rCBF values of the contralateral normal hemispheres at the 1st and the 4th h were significantly lower in the dehydration group (p = 0.027 and 0.040, respectively). Conclusions: Our findings suggested that dehydration status is associated with the progression of infarct volume and decreases in cerebral blood flow during the acute stage of ischemic stroke. This preliminary study provided an imaging clue that more intensive hydration therapies and reperfusion strategies are necessary for the management of acute ischemic stroke patients with dehydration status.

We aimed to evaluate the association of caffeine consumption and caffeine source with mortality among patients with diabetes. Methods: We examined the association of caffeine consumption with mortality among 1974 women and 1974 men with diabetes, using the National Health and Nutrition Examination Survey (NHANES) 1999-2010. Caffeine consumption was assessed at baseline using 24 h dietary recalls. Cox proportional hazard models were fitted to estimate hazard ratios (HR) for all-cause, cardiovascular, and cancer-related mortality according to caffeine consumption and its source, adjusting for potential confounders. Results: A dose-dependent inverse association between caffeine and all-cause mortality was observed in women with diabetes. Adjusted HR for death among women who consumed caffeine, as compared with non-consumers, were: 0.57 (95% CI, 0.40-0.82) for <100 mg of caffeine/day, 0.50 (95% CI, 0.32 0.78) for 100 to <200 mg of caffeine/day, and 0.39 (95% CI, 0.23-0.64) for >=200 mg of caffeine/day (p = 0.005 for trend). This association was not observed in men. There was a significant interaction between sex and caffeine consumption (p = 0.015). No significant association between total caffeine consumption and cardiovascular or cancer mortality was observed. Women who consumed more caffeine from coffee had reduced risk of all-cause mortality (p = 0.004 for trend). Conclusion: Our study showed a dose-dependent protective effect of caffeine consumption on mortality among women with diabetes. PMID- 30294301 TI - Vitamin D Toxicity-A Clinical Perspective. AB - Confusion, apathy, recurrent vomiting, abdominal pain, polyuria, polydipsia, and dehydration are the most often noted clinical symptoms of vitamin D toxicity (VDT; also called vitamin D intoxication or hypervitaminosis D). VDT and its clinical manifestation, severe hypercalcemia, are related to excessive long-term intake of vitamin D, malfunctions of the vitamin D metabolic pathway, or the existence of coincident disease that produces the active vitamin D metabolite locally. Although VDT is rare, the health effects can be serious if it is not promptly identified. Many forms of exogenous (iatrogenic) and endogenous VDT exist. Exogenous VDT is usually caused by the inadvertent or improper intake of extremely high doses of pharmacological preparations of vitamin D and is associated with hypercalcemia. Serum 25-hydroxyvitamin D [25(OH)D] concentrations higher than 150 ng/ml (375 nmol/l) are the hallmark of VDT due to vitamin D overdosing. Endogenous VDT may develop from excessive production of an active vitamin D metabolite - 1,25(OH)2D in granulomatous disorders and in some lymphomas or from the reduced degradation of that metabolite in idiopathic infantile hypercalcemia. Endogenous VDT may also develop from an excessive production of 25(OH)D and 1,25(OH)2D in congenital disorders, such as Williams Beuren syndrome. Laboratory testing during routine clinical examinations may reveal asymptomatic hypercalcemia caused by the intake of vitamin D even in doses recommended for the general population and considered safe. That phenomenon, called hypersensitivity to vitamin D, reflects dysregulated vitamin D metabolism. Researchers have proposed many processes to explain VDT. Those processes include elevated activity of 1alpha-hydroxylase or inhibited activity of 24-hydroxylase, both leading to increased concentration of 1,25(OH)D; increased number of vitamin D receptors; and saturation of the capacity of vitamin D binding protein. Increased public awareness of vitamin D-related health benefits might increase the risk of VDT due to self-administration of vitamin D in doses higher then recommended for age and body weight or even higher than the established upper limit intake values. Consequently, the incidence of hypercalcemia due to hypervitaminosis D might increase. PMID- 30294300 TI - Developmental Exposure to 2,2',4,4'-Tetrabromodiphenyl Ether Permanently Alters Blood-Liver Balance of Lipids in Male Mice. AB - Polybrominated diphenyl ethers (PBDEs) were used as flame-retardant additives starting 1965 and were recently withdrawn from commerce in North America and Europe. Approximately 1/5 of the total U.S. population were born when environmental concentrations of PBDE plateaued at their maximum. Accumulating evidence suggests that developmental exposures to PBDE may result in long-lasting programming of liver metabolism. In this study, CD-1 mice were exposed prenatally or neonatally to 1 mg/kg body weight of 2,2',4,4'-tetrabromodiphenyl ether (BDE 47), and changes in liver histology, transcriptome, and liver-blood balance of triglycerides were analyzed in 10 months old male offspring. In both exposure groups, long-term reprogramming of lipid metabolism was observed, including increased liver triglycerides and decreased blood triglycerides, and altered expression of metabolic genes in the liver. Significant upregulation of lipid influx transporter Cd36 2.3- and 5.7-fold in pre- and neonatal exposure groups, respectively was identified as a potential mechanism of blood/liver imbalance of triglycerides. Analysis of our and previously published all-genome gene expression data identified changes in expression of ribosomal protein genes as a transcriptomic signature of PBDE exposure. Further comparison of our new data and published data demonstrate that low doses (0.2 mg/kg body weight) of PBDE induce long-lasting up-regulation of ribosomal genes, suppression of Cd36 in liver and increase circulating triglycerides in blood, while moderated doses (>=1 mg/kg body weight) produce opposite long-lasting effects. To conclude, this study shows that an environmentally relevant developmental exposures to BDE-47 permanently alter lipid uptake and accumulation in the liver, with low and moderate doses having opposite effect on liver transcriptomics and triglyceride balance. Similar effects of pre- and neonatal exposures point at hepatocyte maturation as a sensitive window of the liver metabolism programming. These results suggest that PBDE exposure may be an important factor increasing risks of cardio-vascular disease and non-alcoholic fatty liver disease via modulation of liver/blood balance of lipids. The translational relevance of these findings for human remain to be studied. PMID- 30294302 TI - Associations Between C-Reactive Protein, Insulin Sensitivity, and Resting Metabolic Rate in Adults: A Mediator Analysis. AB - Objective: Long-term positive energy balance promotes the development of obesity, a main risk factor for type 2 diabetes mellitus (T2DM). While an association between increased resting metabolic rate (RMR) and insulin sensitivity (IS) was shown previously, the underlying mechanisms remain unclear. Aim of the mediator analysis was to investigate the role of inflammation within the association between RMR and IS. Methods: Anthropometric, clinical, and lifestyle data were collected according to standard operating procedures. RMR was measured using indirect calorimetry. Homeostasis model assessment for insulin resistance (HOMA IR) was used as an IS parameter and C-reactive protein (CRP) was measured to represent the inflammatory status. Statistical analyses were performed using SPSS. Results: The analysis included 782 adults (517 females) with a mean age of 32.4 +/- 12.0 years and a mean body mass index (BMI) of 24.6 +/- 5.2 kg/m2. Regression analysis indicated a significant evidence for associations between RMR and HOMA-IR (beta = 39.3 +/- 7.3 kcal/d; p <= 0.001) and CRP and HOMA-IR (beta = 0.5 +/- 0.1; p <= 0.001) after adjustment for fat-free mass, sex, age, and study site. Results of the mediator analysis did not support the hypothesis that CRP is a mediator for the association between RMR and HOMA-IR. These results did not change after participant stratification according to sex or BMI. Conclusion: A significant evidence for an association between RMR and IS was shown in a large cohort. However, the inflammatory status, determined via CRP levels, was not a mediator within this association. PMID- 30294303 TI - An Association of PTPN11 and SHOX Mutations in a Male Presenting With Syndromic Growth Failure. AB - In children with genetic syndromes, short stature is frequently a characteristic feature that, when associated with other specific manifestations, significantly aids in clinical diagnosis. In this report, an atypical case of Noonan syndrome (NS) in a 5.5-year-old child with mesomelic short stature is described. Genetic tests revealed two different mutations in this child. As expected in an NS case, a mutation in PTPN11 gene related to the RAS/MAPK signal transduction pathway was identified. Moreover, a mutation in the SHOX gene that was able to cause disproportionate short stature was detected. A clinical picture of NS with mesomelic short stature makes the diagnosis even more difficult as haploinsufficiency and complete loss of function of SHOX gene are associated with the typical differentiation and proliferation of chondrocytes, leading to mesomelic appearance. This case exemplifies the difficulties that can be encountered in achieving proper diagnoses for children with syndromic diseases and highlights the role of genetic tests in identifying final diagnoses in these patients. PMID- 30294305 TI - Desiccation- and Saline-Tolerant Bacteria and Archaea in Kalahari Pan Sediments. AB - More than 41% of the Earth's land area is covered by permanent or seasonally arid dryland ecosystems. Global development and human activity have led to an increase in aridity, resulting in ecosystem degradation and desertification around the world. The objective of the present work was to investigate and compare the microbial community structure and geochemical characteristics of two geographically distinct saline pan sediments in the Kalahari Desert of southern Africa. Our data suggest that these microbial communities have been shaped by geochemical drivers, including water content, salinity, and the supply of organic matter. Using Illumina 16S rRNA gene sequencing, this study provides new insights into the diversity of bacteria and archaea in semi-arid, saline, and low-carbon environments. Many of the observed taxa are halophilic and adapted to water limiting conditions. The analysis reveals a high relative abundance of halophilic archaea (primarily Halobacteria), and the bacterial diversity is marked by an abundance of Gemmatimonadetes and spore-forming Firmicutes. In the deeper, anoxic layers, candidate division MSBL1, and acetogenic bacteria (Acetothermia) are abundant. Together, the taxonomic information and geochemical data suggest that acetogenesis could be a prevalent form of metabolism in the deep layers of a saline pan. PMID- 30294304 TI - Grow With the Challenge - Microbial Effects on Epithelial Proliferation, Carcinogenesis, and Cancer Therapy. AB - The eukaryotic host is in close contact to myriads of resident and transient microbes, which influence the crucial physiological pathways. Emerging evidence points to their role of host-microbe interactions for controlling tissue homeostasis, cell fate decisions, and regenerative capacity in epithelial barrier organs including the skin, lung, and gut. In humans and mice, it has been shown that the malignant tumors of these organs harbor an altered microbiota. Mechanistic studies have shown that the altered metabolic properties and secreted factors contribute to epithelial carcinogenesis and tumor progression. Exciting recent work points toward a crucial influence of the associated microbial communities on the response to chemotherapy and immune-check point inhibitors during cancer treatment, which suggests that the modulation of the microbiota might be a powerful tool for personalized oncology. In this article, we provide an overview of how the bacterial signals and signatures may influence epithelial homeostasis across taxa from cnidarians to vertebrates and delineate mechanisms, which might be potential targets for therapy of human diseases by either harnessing barrier integrity (infection and inflammation) or restoring uncontrolled proliferation (cancer). PMID- 30294307 TI - Dispersal Modifies the Diversity and Composition of Active Bacterial Communities in Response to a Salinity Disturbance. AB - Dispersal can influence the response of bacterial communities to environmental changes and disturbances. However, the extent to which dispersal contributes to the community response in dependence of the character and strength of the disturbance remains unclear. Here, we conducted a transplant experiment using dialysis bags in which bacterioplankton originating from brackish and marine regions of the Saint Lawrence Estuary were reciprocally incubated in the two environments for 5 days. Dispersal treatments were set-up by subjecting half of the microcosms in each environment to an exchange of cells between the marine and brackish assemblages at a daily exchange rate of 6% (v/v), and the other half of microcosms were kept as the non-dispersal treatments. Bacterial 16S rRNA sequencing was then used to examine the diversity and composition of the active communities. Alpha diversity of the marine communities that were exposed to the brackish environment was elevated greatly by dispersal, but declined in the absence of dispersal. This indicates that dispersal compensated the loss of diversity in the marine communities after a disturbance by introducing bacterial taxa that were able to thrive and coexist with the remaining community members under brackish conditions. On the contrary, alpha diversity of the brackish communities was not affected by dispersal in either environment. Furthermore, dispersal led to an increase in similarity between marine and brackish communities in both of the environments, with a greater similarity when the communities were incubated in the brackish environment. These results suggest that the higher initial diversity in the brackish than in the marine starting community made the resident community less susceptible to dispersing bacteria. Altogether, this study shows that dispersal modifies the diversity and composition of the active communities in response to a salinity disturbance, and enables the local adjustment of specific bacteria under brackish environmental conditions. PMID- 30294306 TI - Determinants of Deadwood-Inhabiting Fungal Communities in Temperate Forests: Molecular Evidence From a Large Scale Deadwood Decomposition Experiment. AB - Despite the important role of wood-inhabiting fungi (WIF) in deadwood decomposition, our knowledge of the factors shaping the dynamics of their species richness and community composition is scarce. This is due to limitations regarding the resolution of classical methods used for characterizing WIF communities and to a lack of well-replicated long-term experiments with sufficient numbers of tree species. Here, we used a large scale experiment with logs of 11 tree species at an early stage of decomposition, distributed across three regions of Germany, to identify the factors shaping WIF community composition and Operational Taxonomic Unit (OTU) richness using next generation sequencing. We found that tree species identity was the most significant factor, corresponding to (P < 0.001) and explaining 10% (representing 48% of the explainable variance) of the overall WIF community composition. The next important group of variables were wood-physicochemical properties, of which wood pH was the only factor that consistently corresponded to WIF community composition. For overall WIF richness patterns, we found that approximately 20% of the total variance was explained by wood N content, location, tree species identity and wood density. It is noteworthy that the importance of determinants of WIF community composition and richness appeared to depend greatly on tree species group (broadleaved vs. coniferous) and it differed between the fungal phyla Ascomycota and Basidiomycota. PMID- 30294308 TI - Diversity of Bradyrhizobia in Subsahara Africa: A Rich Resource. AB - Making use of biological nitrogen fixation (BNF) with pulses and green manure legumes can help to alleviate nitrogen deficiencies and increase soil fertility, problems faced particularly in smallholder agriculture in Subsahara Africa (SSA). The isolation of indigenous rhizobia provides a basis for the formulation of rhizobial inoculants. Moreover, their identification and characterization contribute to the general understanding of species distribution and ecology. Here we discuss global species discovery of Bradyrhizobium spp. Although recently the number of validly published Bradyrhizobium species is rapidly increasing, their diversity in SSA is not well-represented. We summarize the recent knowledge on species diversity in the Bradyrhizobium yuanmingense lineage to which most SSA isolates belong, and their biogeographic distribution and adaptations. Most indigenous rhizobia appear to differ from species found on other continents. We stress that an as yet hidden diversity may be a rich resource for inoculant development in future. As some species are exceptionally temperature tolerant, they may be potential biofertilizer candidates for global warming scenarios. PMID- 30294309 TI - Efficiency of Biosynthesized Silver and Zinc Nanoparticles Against Multi-Drug Resistant Pathogens. AB - Biosynthesis of metallic nanoparticles has acquired particular attention due to its economic feasibility, low toxicity, and simplicity of the process. In this study, extracellular synthesis of silver and zinc nanoparticle was carried out by Pseudomonas hibiscicola isolated from the effluent of an electroplating industry in Mumbai. Characterization studies revealed synthesis of 40 and 60 nm nanoparticles of silver (AgNP) and zinc (ZnNP), respectively, with distinct morphology as observed in TEM and its crystalline nature confirmed by XRD. DLS, zeta potential, NTA, and FTIR studies further characterized nanoparticles giving data about its size, stability, and functional groups. Considering the toxicity of nanoparticles the evaluation of antimicrobial activity was studied in the range of non-toxic concentration for normal cell lines. Silver nanoparticles were found to be the most effective antimicrobial against all tested strains and drug resistant clinical isolates of MRSA, VRE, ESBL, MDR, Pseudomonas aeruginosa with MIC in the range of 1.25-5 mg/ml. Zinc nanoparticles were found to be specifically active against Gram-positive bacteria like Staphylococcus aureus including its drug-resistant variant MRSA. Both AgNP and ZnNP were found to be effective against Mycobacterium tuberculosis and its MDR strain with MIC of 1.25 mg/ml. The synergistic action of nanoparticles assessed in combination with a common antibiotic gentamicin (590 MUg/mg) used for the treatment of various bacterial infections by Checker board assay. Silver nanoparticles profoundly exhibited synergistic antimicrobial activity against drug-resistant strains of MRSA, ESBL, VRE, and MDR P. aeruginosa while ZnNP were found to give synergism with gentamicin only against MRSA. The MRSA, ESBL, and P. aeruginosa strains exhibited MIC of 2.5 mg/ml except VRE which was 10 mg/ml for both AgNPs and ZnNPs. These results prove the great antimicrobial potential of AgNP and ZnNP against drug-resistant strains of community and hospital-acquired infections and opens a new arena of antimicrobials for treatment, supplementary prophylaxis, and prevention therapy. PMID- 30294310 TI - Genomic Characterization and Probiotic Potency of Bacillus sp. DU-106, a Highly Effective Producer of L-Lactic Acid Isolated From Fermented Yogurt. AB - Bacillus sp. DU-106, a newly isolated member of Bacillus cereus group, exhibits the predominant ability to produce L-lactic acid. The probiotic potency of test strain revealed its survivability at acidic pH, bile salts and viability in simulated gastric juice in vitro. The acute oral toxicity test indicated its no toxicity to laboratory mice in vivo. We further determined the complete genome of strain DU-106 to understand genetic basis as a potential probiotic. It has a circular chromosome and three plasmids for a total genome 5,758,208 bp in size with a G + C content of 35.10%. Genes associated with lactate synthesis were found in the DU-106 genome. We also annotated various stress-related, bile salt resistance, and adhesion-related domains in this strain, which likely provide support in exerting probiotic action by enabling adhesion to host epithelial cells and survival under gastrointestinal tract. Moreover, strain DU-106 genome lacks the virulence genes encodes cereulide synthetase, enterotoxin FM, and cytotoxin K. These phenotypic and genomic probiotic potencies facilitate its potential candidate as probiotic starter in food industry. PMID- 30294312 TI - Characterization of Cell Envelope Multiple Mutants of Brucella ovis and Assessment in Mice of Their Vaccine Potential. AB - Brucella ovis is a non-zoonotic Brucella species lacking specific vaccine. It presents a narrow host range, a unique biology relative to other Brucella species, and important distinct surface properties. To increase our knowledge on its peculiar surface and virulence features, and seeking to develop a specific vaccine, multiple mutants for nine relevant cell-envelope-related genes were investigated. Mutants lacking Omp10 plus Omp19 could not be obtained, suggesting that at least one of these lipoproteins is required for viability. A similar result was obtained for the double deletion of omp31 and omp25 that encode two major surface proteins. Conversely, the absence of major Omp25c (proved essential for internalization in HeLa cells) together with Omp25 or Omp31 was tolerated by the bacterium. Although showing important in vitro and in vivo defects, the Deltaomp10Deltaomp31Deltaomp25c mutant was obtained, demonstrating that B. ovis PA survives to the simultaneous absence of Omp10 and four out seven proteins of the Omp25/Omp31 family (i.e., Omp31, Omp25c, Omp25b, and Omp31b, the two latter naturally absent in B. ovis). Three multiple mutants were selected for a detailed analysis of virulence in the mouse model. The Deltaomp31Deltacgs and Deltaomp10Deltaomp31Deltaomp25c mutants were highly attenuated when inoculated at 106 colony forming units/mouse but they established a persistent infection when the infection dose was increased 100-fold. The Deltaomp10DeltaugpBDeltaomp31 mutant showed a similar behavior until week 3 post-infection but was then totally cleared from spleen. Accordingly, it was retained as vaccine candidate for mice protection assays. When compared to classical B. melitensis Rev1 heterologous vaccine, the triple mutant induced limited splenomegaly, a significantly higher antibody response against whole B. ovis PA cells, an equivalent memory cellular response and, according to spleen colonization measurements, better protection against a challenge with virulent B. ovis PA. Therefore, it would be a good candidate to be evaluated in the natural host as a specific vaccine against B. ovis that would avoid the drawbacks of B. melitensis Rev1. In addition, the lack in this attenuated strain of Omp31, recognized as a highly immunogenic protein during B. ovis infection, would favor the differentiation between infected and vaccinated animals using Omp31 as diagnostic target. PMID- 30294311 TI - Characterization and Salt Response in Recurrent Halotolerant Exiguobacterium sp. SH31 Isolated From Sediments of Salar de Huasco, Chilean Altiplano. AB - Poly-extremophiles microorganisms have the capacity to inhabit hostile environments and can survive several adverse conditions that include as variations in temperature, pH, and salinity, high levels UV light and atmospheric pressure, and even the presence of toxic compounds and the formation of reactive oxygen species (ROS). A halotolerant Exiguobacterium strain was isolated from Salar de Huasco (Chilean Altiplano), a well-known shallow lake area with variable salinity levels, little human intervention, and extreme environmental conditions, which makes it ideal for the study of resistant mechanisms and the evolution of adaptations. This bacterial genus has not been extensively studied, although its cosmopolitan location indicates that it has high levels of plasticity and adaptive capacity. However, to date, there are no studies regarding the tolerance and resistance to salinity and osmotic pressure. We set out to characterize the Exiguobacterium sp. SH31 strain and describe its phenotypical and genotypical response to osmotic stress. In this context, as a first step to characterize the response to the SH31 strain to salinity and to establish the bases for a molecular study, we proposed to compare its response under three salt conditions (0, 25, and 50 g/l NaCl). Using different physiology, genomic, and transcriptomic approaches, we determined that the bacterium is able to grow properly in a NaCl concentration of up to 50 g/l; however, the best growth rate was observed at 25 g/l. Although the presence of flagella is not affected by salinity, motility was diminished at 25 g/l NaCl and abolished at 50 g/l. Biofilm formation was induced proportionally with increases in salinity, which was expected. These phenotypic results correlated with the expression of related genes: fliG and fliS Motility); opuBA and putP (transport); glnA, proC, gltA, and gbsA (compatible solutes); ywqC, bdlA, luxS y pgaC (biofilm and stress response); and therefore, we conclude that this strain effectively modifies gene expression and physiology in a differential manner when faced with different concentrations of NaCl and these modifications aid survival. PMID- 30294314 TI - Surveillance for Azole-Resistant Aspergillus fumigatus in a Centralized Diagnostic Mycology Service, London, United Kingdom, 1998-2017. AB - Background/Objectives: Aspergillus fumigatus is the leading cause of invasive aspergillosis. Treatment is hindered by the emergence of resistance to triazole antimycotic agents. Here, we present the prevalence of triazole resistance among clinical isolates at a major centralized medical mycology laboratory in London, United Kingdom, in the period 1998-2017. Methods: A large number (n = 1469) of clinical A. fumigatus isolates from unselected clinical specimens were identified and their susceptibility against three triazoles, amphotericin B and three echinocandin agents was carried out. All isolates were identified phenotypically and antifungal susceptibility testing was carried out by using a standard broth microdilution method. Results: Retrospective surveillance (1998-2011) shows 5/1151 (0.43%) isolates were resistant to at least one of the clinically used triazole antifungal agents. Prospective surveillance (2015-2017) shows 7/356 (2.2%) isolates were resistant to at least one triazole antifungals demonstrating an increase in incidence of triazole-resistant A. fumigatus in our laboratory. Among five isolates collected from 2015 to 2017 and available for molecular testing, three harbored TR34/L98H alteration in the cyp51A gene that are associated with the acquisition of resistance in the non-patient environment. Conclusion: These data show that historically low prevalence of azole resistance may be increasing, warranting further surveillance of susceptible patients. PMID- 30294313 TI - Optimization and Lead Selection of Benzothiazole Amide Analogs Toward a Novel Antimycobacterial Agent. AB - Mycobacteria remain an important problem worldwide, especially drug resistant human pathogens. Novel therapeutics are urgently needed to tackle both drug resistant tuberculosis (TB) and difficult-to-treat infections with nontuberculous mycobacteria (NTM). Benzothiazole adamantyl amide had previously emerged as a high throughput screening hit against M. tuberculosis (Mtb) and was subsequently found to be active against NTM as well. For lead optimization, we applied an iterative process of design, synthesis and screening of several 100 analogs to improve antibacterial potency as well as physicochemical and pharmacological properties to ultimately achieve efficacy. Replacement of the adamantyl group with cyclohexyl derivatives, including bicyclic moieties, resulted in advanced lead compounds that showed excellent potency and a mycobacteria-specific spectrum of activity. MIC values ranged from 0.03 to 0.12 MUg/mL against M. abscessus (Mabs) and other rapid- growing NTM, 1-2 MUg/mL against M. avium complex (MAC), and 0.12-0.5 MUg/mL against Mtb. No pre-existing resistance was found in a collection of n = 54 clinical isolates of rapid-growing NTM. Unlike many antibacterial agents commonly used to treat mycobacterial infections, benzothiazole amides demonstrated bactericidal effects against both Mtb and Mabs. Metabolic labeling provided evidence that the compounds affect the transfer of mycolic acids to their cell envelope acceptors in mycobacteria. Mapping of resistance mutations pointed to the trehalose monomycolate transporter (MmpL3) as the most likely target. In vivo efficacy and tolerability of a benzothiazole amide was demonstrated in a mouse model of chronic NTM lung infection with Mabs. Once daily dosing over 4 weeks by intrapulmonary microspray administration as 5% corn oil/saline emulsion achieved statistically significant CFU reductions compared to vehicle control and non-inferiority compared to azithromycin. The benzothiazole amides hold promise for development of a novel therapeutic agent with broad antimycobacterial activity, though further work is needed to develop drug formulations for direct intrapulmonary delivery via aerosol. PMID- 30294315 TI - Engineering Heterologous Production of Salicylate Glucoside and Glycosylated Variants. AB - Salicylate 2-O-beta-D-glucoside (SAG) is a plant-derived natural product with potential utility as both an anti-inflammatory and as a plant protectant compound. Heterologous biosynthesis of SAG has been established in Escherichia coli through metabolic engineering of the shikimate pathways and introduction of a heterologous biosynthetic step to allow a more directed route to the salicylate precursor. The final SAG compound resulted from the separate introduction of an Arabidopsis thaliana glucosyltransferase enzyme. In this study, a range of heterologous engineering parameters were varied (including biosynthetic pathway construction, expression plasmid, and E. coli strain) for the improvement of SAG specific production in conjunction with a system demonstrating improved plasmid stability. In addition, the glucoside moiety of SAG was systematically varied through the introduction of the heterologous oliose and olivose deoxysugar pathways. Production of analogs was observed for each newly constructed pathway, demonstrating biosynthetic diversification potential; however, production titers were reduced relative to the original SAG compound. PMID- 30294316 TI - Acyl Carrier Protein 3 Is Involved in Oxidative Stress Response in Pseudomonas aeruginosa. AB - The human opportunistic pathogen Pseudomonas aeruginosa expresses three acyl carrier proteins (ACPs): AcpP, Acp1, and Acp3. The function of AcpP in membrane fatty acid synthesis (FAS) was confirmed recently, but the physiological roles of Acp1 and Acp3 remain unclear. To address this, we investigated the physiological role of Acp3 in P. aeruginosa. We found that expression of Acp3 dramatically increases in the log phase of cell growth and that its transcription is under the control of the QS regulators LasR and RhlR. Deletion of acp3 from P. aeruginosa strain PAO1 results in thicker biofilm formation, increased resistance of the strain to hydrogen peroxide, and higher persistence in a mouse infection model. Tandem affinity purification (TAP) experiments revealed several novel protein binding partners of Acp3, including KatA, the major catalase in P. aeruginosa. Acp3 was found to repress the catalase activity of KatA and, consistent with inhibition by Acp3, less reactive oxygen species are present in the acp3 deletion strain. Overall, our study reveals that Acp3 has a distinct function from that of the canonical AcpP and may be involved in the oxidative stress response. PMID- 30294317 TI - A Nematode of the Mid-Atlantic Ridge Hydrothermal Vents Harbors a Possible Symbiotic Relationship. AB - Deep-sea hydrothermal vent meiofauna have been the focus of recent research and the discovery of an abundant well-adapted free-living marine nematode on the Mid Atlantic Ridge offers new perspectives on adaptations to the vent environment. Indeed, knowledge concerning biological interactions of microbes and meiofauna in marine extreme environments is scarce, especially for nematodes. In this study, we used microscopic observations [fluorescence in situ hybridization (FISH) and scanning electron microscopy (SEM)] and metabarcoding of 16S rRNA to characterize the bacterial community of the nematode species Oncholaimus dyvae, an overlooked but ecologically important vent organism. Detection of bacteria in the buccal cavity and on the cuticle (SEM) and epibionts in its intestine (FISH) suggests that O. dyvae harbors its own bacterial community. Molecular results and phylogenetic analysis show that bacteria associated with this species are related to symbiotic lineages typical of hydrothermal vent fauna, such as sulfur oxidizing bacteria related to Epsilonproteobacteria and Gammaproteobacteria. This multi-approach study suggests a potential symbiotic role of bacteria with its nematode host and opens new research perspectives on vent meiofauna. PMID- 30294319 TI - Gene Expression Order Attributed to Genome Reduction and the Steady Cellular State in Escherichia coli. AB - Transcriptomes not only reflect the growth status but also link to the genome in bacteria. To investigate if and how genome or cellular state changes contribute to the gene expression order, the growth profile-associated transcriptomes of an assortment of genetically differentiated Escherichia coli either exponentially growing under varied conditions or in response to environmental disturbance were analyzed. A total of 168 microarray data sets representing 56 transcriptome variations, were categorized by genome size (full length or reduced) and cellular state (steady or unsteady). At the genome-wide level, the power-law distribution of gene expression was found to be significantly disturbed by the genome size but not the cellular state. At the regulatory network level, more networks with improved coordination of growth rates were observed in genome reduction than at the steady state. At the single-gene level, both genome reduction and steady state increased the correlation of gene expression to growth rate, but the enriched gene categories with improved correlations were different. These findings not only illustrate the order of gene expression attributed to genome reduction and steady cellular state but also indicate that the accessory sequences acquired during genome evolution largely participated in the coordination of transcriptomes to growth fitness. PMID- 30294318 TI - Accessory Toxins of Vibrio Pathogens and Their Role in Epithelial Disruption During Infection. AB - Gastrointestinal episodes associated with Vibrio species have been rising worldwide in the last few years. Consequently, it is important to comprehend how occurs the production of diarrhea, to establish new preventive and therapeutic measures. Besides the classical CT and TCP toxins, Zot, RTX, and Ace among others have been deeply studied in V. cholerae. However, in other Vibrio species of clinical interest, where some of these toxins have been reported, there is practically no information. Zot activates a cascade of signals inside of the cell that increase the permeability of epithelial barrier, while RTX causes depolymerization of the actin cytoskeleton and Ace increases the permeability of intestinal cell monolayers. The goal of this study is to acquire information about the distribution of these toxins in human pathogenic Vibrios and to review the progress in the study of their role in the intestinal epithelium during infection. PMID- 30294320 TI - Functional Characterization of Cryptococcal Genes: Then and Now. AB - Site-directed mutagenesis enables researchers to switch a gene of interest off for functional characterization of the gene. In the pathogenic yeasts, Cryptococcus neoformans and sister species C. deneoformans, this is almost exclusively achieved by introducing DNA into cells through either biolistic transformation or electroporation. The targeted gene is then disrupted by homologous recombination (HR) between the gene and the transforming DNA. Both techniques have downsides; biolistic transformation equipment is very expensive, limiting the use thereof to well-resourced laboratories, and HR occurs at extremely low frequencies in electroporated cryptococcal cells, making this method unappealing for gene targeting when not making use of additional modifications or methods to enhance HR in these cells. One approach to increase the frequency of HR in electroporated cryptococcal cells have recently been described. In this approach, CRISPR-Cas9 technology is utilized to form a double strand break in the targeted gene where after the occurrence of HR seems to be higher. The less expensive electroporation technique can therefore be used to deliver the CRISPR-Cas9 components into cells to disrupt a gene of interest, but only if the CRISPR components can be maintained for long enough in cells to enable their expression. Maintenance of episomal DNA occurs readily in C. deneoformans, but only under certain conditions in C. neoformans. In addition, CRISPR-Cas9 allows for gene complementation in order to fulfill Falkow's molecular Koch's postulates and adds other novel methods for studying genes as well, such as the addition of a fluorophore to an inactive Cas9 enzyme to highlight the location of a gene in a chromosome. These developments add less expensive alternatives to current methods, which could lead to more research on this yeast in developing countries where cryptococcal infections are more prevalent and researchers have access to more clinical isolates.

AB - The emergence of New Delhi metallo-beta-lactamase (NDM) in common enterobacterial species is a major concern for healthcare. Early reports have revealed that the spread of NDM involved diverse and heterogeneous plasmids. Recently, the involvement of a rare, IncX3 subtype plasmid has been increasingly recognized. Here, we studied the prevalence of IncX plasmid subtypes in 198 carbapenem resistant Enterobacteriaceae, originating from a territory-wide active surveillance in Hong Kong in 2016. The complete sequences and biological features of the bla NDM-carrying plasmids were investigated. A total of 62 NDM-type, 21 OXA-48 type, 14 IMP-type, 8 KPC-type, 4 IMI-type producers, and 89 non carbapenemase-producers were tested for presence of IncX subtypes. IncX3 (n = 60) was the most common subtype, followed by IncX4 (n = 6) and IncX1 (n = 2). The prevalence of IncX3 subtype in isolates producing NDM, other carbapenemase types and non-carbapenemase producers were 75.8, 21.3, and 3.4%, respectively (P < 0.001). An IncX3 plasmid (size ~50 kb) was confirmed to carry bla NDM in 47 isolates of different enterobacterial species. Thirteen IncX3 plasmids originating from six healthcare regions in Hong Kong were completely sequenced. The results showed that the IncX3 plasmids carrying bla NDM share a high degree of sequence identity with a previously reported plasmid, pNDM-HN380 (GenBank accession JX104760), over the backbone and genetic load regions. A blast search further revealed the occurrence of identical or nearly identical IncX3 plasmids carrying bla NDM in other part of China, Korea, Myanmar, India, Oman, Kuwait, Italy, and Canada. Two IncX3 carrying bla NDM were investigated further. Conjugation experiments demonstrated that the IncX3 plasmids could be efficiently transferred to multiple enterobacterial species at frequencies that are comparable or higher than the epidemic IncFII plasmid carrying bla CTX-M (pHK01). In addition, efficient transfer of the NDM plasmids occurred over a range of temperatures. In conclusion, this study demonstrated the important role played by IncX3 in the dissemination of NDM and the occurrence of pNDM-HN380-like plasmids in geographically widespread areas. The high mobility of IncX3 plasmid across different enterobacterial species highlights the ability of this plasmid replicon to be an important vehicle in worldwide dissemination of NDM. PMID- 30294324 TI - A Novel Antigen-Sampling Cell in the Teleost Gill Epithelium With the Potential for Direct Antigen Presentation in Mucosal Tissue. AB - In mammals, M cells can take up antigens through mucosal surfaces of the gut and the respiratory tract. Since M cells are deficient of lysosomes and phagosomes, the antigens are directly delivered to the mucosa-associated lymphoid tissue (MALT) without degradation. In teleost fish, the entire body surface (gills, skin, and intestinal system) is covered by mucus; however, specific antigen sampling cells have not yet been identified in their mucosal tissues. Here, we show that two phenotypes of antigen-sampling cells take up antigens through epithelial surfaces of the rainbow trout gill. One phenotype of antigen-sampling cells has features of monocyte/macrophage/dendritic cell-type cells; they have large vacuoles in the cytoplasm and express PTPRC (CD45), CD83, IL-1beta, and IL 12p40b. The second phenotype exhibits similar characteristics to mammalian M cells; the corresponding cells bind the lectin UEA-1 but not WGA and show expression of M cell marker gene Anxa5. In contrast to mammalian M cells, teleost M-type cells were found to exhibit small vacuoles in their cytoplasm and to express almost all genes related to the "phagosome", "lysosome," and "antigen processing and presentation" pathways. Furthermore, MHC class II was constitutively expressed on a fraction of M-type cells, and this expression was significantly increased after antigen uptake, suggesting that the MHC class II is inducible by antigen stimulation. Here, we suggest that teleost M-type cells play a role in the phylogenetically primitive teleost immune system, similar to bona fide M cells. In addition, the presence of MHC class II expression suggests an additional role in antigen presentation in the gills, which are an organ with high T cell abundance, especially in interbranchial lymphoid tissue. The present results suggest an unconventional antigen presentation mechanism in the primitive mucosal immune system of teleosts, which generally lack highly organized lymphoid tissues. Moreover, the results of this work may be valuable for the development of mucosal vaccines that specifically target M-type cells; mucosal vaccines significantly reduce working costs and the stress that is usually induced by vaccination via injection of individual fish. PMID- 30294325 TI - Anaphylatoxin Receptors C3aR and C5aR1 Are Important Factors That Influence the Impact of Ethanol on the Adipose Secretome. AB - Background and aims: Chronic ethanol exposure results in inflammation in adipose tissue; this response is associated with activation of complement as well as the development of alcohol-related liver disease (ALD). Adipose communicates with other organs, including liver, via the release of soluble mediators, such as adipokines and cytokines, characterized as the "adipose secretome." Here we investigated the role of the anaphaylatoxin receptors C3aR and C5aR1 in the development of adipose tissue inflammation and regulation of the adipose secretome in murine ALD (mALD). Methods: Wild-type C57BL/6 (WT), C3aR -/-, and C5aR1 -/- mice were fed Lieber-DeCarli ethanol diet for 25 days (6% v/v, 32% kcal) or isocaloric control diets; indicators of inflammation and injury were assessed in gonadal adipose tissue. The adipose secretome was characterized in isolated adipocytes and stromal vascular cells. Results: Ethanol feeding increased the expression of adipokines, chemokines and leukocyte markers in gonadal adipose tissue from WT mice; C3aR -/- were partially protected while C5aR1 -/- mice were completely protected. In contrast, induction of CYP2E1 and accumulation of TUNEL-positive cells in adipose in response to ethanol feeding was independent of genotype. Bone marrow chimeras, generated with WT and C5aR1 -/ mice, revealed C5aR1 expression on non-myeloid cells, likely to be adipocytes, contributed to ethanol-induced adipose inflammation. Chronic ethanol feeding regulated both the quantity and distribution of adipokines secreted from adipocytes in a C5aR1-dependent mechanism. In WT mice, chronic ethanol feeding induced a predominant release of pro-inflammatory adipokines from adipocytes, while the adipose secretome from C5aR1 -/- mice was characterized by an anti inflammatory/protective profile. Further, the cargo of adipocyte-derived extracellular vesicles (EVs) was distinct from the soluble secretome; in WT EVs, ethanol increased the abundance of pro-inflammatory mediators while EV cargo from C5aR1 -/- adipocytes contained a greater diversity and more robust expression of adipokines. Conclusions: C3aR and C5aR1 are potent regulators of ethanol-induced adipose inflammation in mALD. C5aR1 modulated the impact of chronic ethanol on the content of the adipose secretome, as well as influencing the cargo of an extensive array of adipokines from adipocyte-derived EVs. Taken together, our data demonstrate that C5aR1 contributes to ethanol-mediated changes in the adipose secretome, likely contributing to intra-organ injury in ALD. PMID- 30294323 TI - Going to Bat(s) for Studies of Disease Tolerance. AB - A majority of viruses that have caused recent epidemics with high lethality rates in people, are zoonoses originating from wildlife. Among them are filoviruses (e.g., Marburg, Ebola), coronaviruses (e.g., SARS, MERS), henipaviruses (e.g., Hendra, Nipah) which share the common features that they are all RNA viruses, and that a dysregulated immune response is an important contributor to the tissue damage and hence pathogenicity that results from infection in humans. Intriguingly, these viruses also all originate from bat reservoirs. Bats have been shown to have a greater mean viral richness than predicted by their phylogenetic distance from humans, their geographic range, or their presence in urban areas, suggesting other traits must explain why bats harbor a greater number of zoonotic viruses than other mammals. Bats are highly unusual among mammals in other ways as well. Not only are they the only mammals capable of powered flight, they have extraordinarily long life spans, with little detectable increases in mortality or senescence until high ages. Their physiology likely impacted their history of pathogen exposure and necessitated adaptations that may have also affected immune signaling pathways. Do our life history traits make us susceptible to generating damaging immune responses to RNA viruses or does the physiology of bats make them particularly tolerant or resistant? Understanding what immune mechanisms enable bats to coexist with RNA viruses may provide critical fundamental insights into how to achieve greater resilience in humans. PMID- 30294327 TI - Functional Inhibitory Siglec-6 Is Upregulated in Human Colorectal Cancer Associated Mast Cells. AB - Mast cells (MC) accumulate in colorectal cancer (CRC) and the relationship between MC density and cancer progression has been well recognized. MC can be either pro-tumor or anti-tumor players, depending on the local factors present in the tumor microenvironment. Upon malignant transformation, cancer cells express high levels of sialic acids on cell membrane or by secretion. Siglecs are a family of immunoglobulin-like receptors that bind sialic acids and each subtype has a distinct pattern of expression on immune cells. Among them, Siglec-6 is expressed predominately by MC. However, the function of Siglec-6 in MC is largely unexplored and whether it is expressed by CRC-associated MC remains unknown. In this study, we explored the function of Siglec-6 in CD34+ derived human MC. MC activation was initiated by IgE crosslinking with or without preincubation of anti-Siglec-6 Ab. Siglec-6 engagement significantly attenuated IgE-dependent MC degranulation as measured by beta-hexosaminidase release and CD63 expression. Interestingly, the production of GM-CSF was also shown reduced upon Siglec-6 engagement. To mimic the milieu of CRC, we cultured primary human MC with colon cancer cells or under hypoxia and Siglec-6 was then measured on these conditioned MC. Coculture with colon cancer cells (HT29 and Caco2) induced upregulation of Siglec-6 on MC. In comparison, normal colon cells (CCD841) had no effect. Also, a time-dependent increase of Siglec-6 by MC was observed under 1% O2. Immunohistochemistry of CRC tissue showed expression of Siglec-6 by MC in submucosa. Lectin immunochemistry revealed the presence of actual ligands for Siglec-6 in human CRC tissues. Together, our findings illustrate that Siglec-6 is a functionally inhibitory receptor on MC and suggest that Siglec-6 expression may be relevant for MC activity in the tumor microenvironment of CRC. PMID- 30294326 TI - CD38 Antibodies in Multiple Myeloma: Mechanisms of Action and Modes of Resistance. AB - MM cells express high levels of CD38, while CD38 is expressed at relatively low levels on normal lymphoid and myeloid cells, and in some non-hematopoietic tissues. This expression profile, together with the role of CD38 in adhesion and as ectoenzyme, resulted in the development of CD38 antibodies for the treatment of multiple myeloma (MM). At this moment several CD38 antibodies are at different phases of clinical testing, with daratumumab already approved for various indications both as monotherapy and in combination with standards of care in MM. CD38 antibodies have Fc-dependent immune effector mechanisms, such as complement dependent cytotoxicity (CDC), antibody-dependent cellular cytotoxicity (ADCC), and antibody-dependent cellular phagocytosis (ADCP). Inhibition of ectoenzymatic function and direct apoptosis induction may also contribute to the efficacy of the antibodies to kill MM cells. The CD38 antibodies also improve host-anti-tumor immunity by the elimination of regulatory T cells, regulatory B cells, and myeloid-derived suppressor cells. Mechanisms of primary and/or acquired resistance include tumor-related factors, such as reduced cell surface expression levels of the target antigen and high levels of complement inhibitors (CD55 and CD59). Differences in frequency or activity of effector cells may also contribute to differences in outcome. Furthermore, the microenvironment protects MM cells to CD38 antibody-induced ADCC by upregulation of anti-apoptotic molecules, such as survivin. Improved understanding of modes of action and mechanisms of resistance has resulted in rationally designed CD38-based combination therapies, which will contribute to further improvement in outcome of MM patients. PMID- 30294328 TI - Avelumab, an IgG1 anti-PD-L1 Immune Checkpoint Inhibitor, Triggers NK Cell Mediated Cytotoxicity and Cytokine Production Against Triple Negative Breast Cancer Cells. AB - The standard treatment for Triple Negative Breast Cancer (TNBC) patients is cytotoxic chemotherapy, but it is restricted since the duration of response is usually short. Blocking the PD-1/PD-L1 pathway through monoclonal antibodies (mAbs) appears to be a promising therapeutic strategy for TNBC patients. Avelumab is a human IgG1 anti-PD-L1 mAb being tested in clinical trials that may also trigger antibody-dependent cell-mediated cytotoxicity (ADCC) against cancer cells as an additional antitumor activity. In the present work, we studied in vitro Avelumab-mediated ADCC against a panel of TNBC cells with different PD-L1 expression using peripheral blood mononuclear cells (PBMC) or purified NK cells from healthy donors. We determined that Avelumab significantly enhanced NK-cell mediated cytotoxicity against TNBC cells and that tumor cells expressing higher levels of PD-L1 were more sensitive to Avelumab-mediated ADCC. IFN-gamma treatment upregulated PD-L1 expression in tumor cells but had a variable impact on Avelumab-mediated ADCC, which could be related to the simultaneous effect of IFN-gamma on the expression of NK cell ligands. Moreover, IL-2 and IL-15 stimulation of NK cells enhanced Avelumab-triggered cytokine production and degranulation along with increased lytic activity against tumor cells. Improving the treatment of TNBC remains still a considerable challenge. This in vitro study suggests that Avelumab-mediated ADCC, independently of the blockade of the PD 1/PD-L1 pathway, could be a valuable mechanism for tumor cell elimination in TNBC. Avelumab combination with immunomodulators such as IL-15 or IL-2 could be taken into consideration to increase the therapeutic efficacy of Avelumab in TNBC. PMID- 30294322 TI - Genetic Alterations of TRAF Proteins in Human Cancers. AB - The tumor necrosis factor receptor (TNF-R)-associated factor (TRAF) family of cytoplasmic adaptor proteins regulate the signal transduction pathways of a variety of receptors, including the TNF-R superfamily, Toll-like receptors (TLRs), NOD-like receptors (NLRs), RIG-I-like receptors (RLRs), and cytokine receptors. TRAF-dependent signaling pathways participate in a diverse array of important cellular processes, including the survival, proliferation, differentiation, and activation of different cell types. Many of these TRAF dependent signaling pathways have been implicated in cancer pathogenesis. Here we analyze the current evidence of genetic alterations of TRAF molecules available from The Cancer Genome Atlas (TCGA) and the Catalog of Somatic Mutations in Cancer (COSMIC) as well as the published literature, including copy number variations and mutation landscape of TRAFs in various human cancers. Such analyses reveal that both gain- and loss-of-function genetic alterations of different TRAF proteins are commonly present in a number of human cancers. These include pancreatic cancer, meningioma, breast cancer, prostate cancer, lung cancer, liver cancer, head and neck cancer, stomach cancer, colon cancer, bladder cancer, uterine cancer, melanoma, sarcoma, and B cell malignancies, among others. Furthermore, we summarize the key in vivo and in vitro evidence that demonstrates the causal roles of genetic alterations of TRAF proteins in tumorigenesis within different cell types and organs. Taken together, the information presented in this review provides a rationale for the development of therapeutic strategies to manipulate TRAF proteins or TRAF-dependent signaling pathways in different human cancers by precision medicine. PMID- 30294329 TI - Systemic ST6Gal-1 Is a Pro-survival Factor for Murine Transitional B Cells. AB - Humoral immunity depends on intrinsic B cell developmental programs guided by systemic signals that convey physiologic needs. Aberrant cues or their improper interpretation can lead to immune insufficiency or a failure of tolerance and autoimmunity. The means by which such systemic signals are conveyed remain poorly understood. Hence, further insight is essential to understanding and treating autoimmune diseases and to the development of improved vaccines. ST6Gal-1 is a sialyltransferase that constructs the alpha2,6-sialyl linkage on cell surface and extracellular glycans. The requirement for functional ST6Gal-1 in the development of humoral immunity is well documented. Canonically, ST6Gal-1 resides within the intracellular ER-Golgi secretory apparatus and participates in cell-autonomous glycosylation. However, a significant pool of extracellular ST6Gal-1 exists in circulation. Here, we segregate the contributions of B cell intrinsic and extrinsic ST6Gal-1 to B cell development. We observed that B cell-intrinsic ST6Gal-1 is required for marginal zone B cell development, while B cell non autonomous ST6Gal-1 modulates B cell development and survival at the early transitional stages of the marrow and spleen. Exposure to extracellular ST6Gal-1 ex vivo enhanced the formation of IgM-high B cells from immature precursors, and increased CD23 and IgM expression. Extrinsic sialylation by extracellular ST6Gal 1 augmented BAFF-mediated activation of the non-canonical NF-kB, p38 MAPK, and PI3K/AKT pathways, and accelerated tyrosine phosphorylation after B cell receptor stimulation. in vivo, systemic ST6Gal-1 did not influence homing of B cells to the spleen but was critical for their long-term survival and systemic IgG levels. Circulatory ST6Gal-1 levels respond to inflammation, infection, and malignancy in mammals, including humans. In turn, we have shown previously that systemic ST6Gal 1 regulates inflammatory cell production by modifying bone marrow myeloid progenitors. Our data here point to an additional role of systemic ST6Gal-1 in guiding B cell development, which supports the concept that circulating ST6Gal-1 is a conveyor of systemic cues to guide the development of multiple branches of immune cells. PMID- 30294331 TI - Role of Matrix Metalloproteinase-2 in Eosinophil-Mediated Airway Remodeling. AB - Airway remodeling is responsible for the progressive decline of lung function in bronchial asthma. Matrix metalloproteinase-2 and fibroblast-to-myofibroblast transition are involved in tissue remodeling. Here we evaluated whether eosinophils play a role in fibroblasts-to-myofibroblasts transition and in the expression of matrix metalloproteinase-2. We co-cultured human eosinophils with human fetal lung fibroblast-1 cells, assessed the expression of remodeling associated molecules by immunoassays and polymerase-chain reaction, and eosinophils-mediated migration of human fetal lung fibroblast-1 cells using a Boyden chamber. To clarify the participation of matrix metalloproteinase-2 in airway remodeling we administered bone marrow-derived eosinophils by intra tracheal route to transgenic mice overexpressing the human matrix metalloproteinase-2. The expression of alpha-smooth muscle actin significantly increased in human fetal lung fibroblast-1 cells co-cultured with human eosinophils compared to controls. There was enhanced expression of matrix metalloproteinase-2 during fibroblast-to-myofibroblast transition. An inhibitor of matrix metalloproteinases blocked eosinophils-associated fibroblast-to myofibroblast transition and increased migration of fibroblasts. The human matrix metalloproteinase-2 transgenic mice receiving adoptive transfer of mouse eosinophils exhibited increased inflammation and advanced airway remodeling compared to wild type mice. This study demonstrated that eosinophils induce fibroblast-to-myofibroblast transition, secretion of matrix metalloproteinase-2, accelerated migration of fibroblasts, and promote matrix metalloproteinase-2 related airway remodeling. These findings provide a novel mechanistic pathway for eosinophil-associated airway remodeling in bronchial asthma. PMID- 30294330 TI - The Role of Complement Activating Collectins and Associated Serine Proteases in Patients With Hematological Malignancies, Receiving High-Dose Chemotherapy, and Autologous Hematopoietic Stem Cell Transplantations (Auto-HSCT). AB - We conducted a prospective study of 312 patients (194 with multiple myeloma, 118 with lymphomas) receiving high-dose conditioning chemotherapy and autologous hematopoietic stem cell transplantation (auto-HSCT). Polymorphisms of MBL2 and MASP2 genes were investigated and serial measurements of serum concentrations of mannose-binding lectin (MBL), CL-LK collectin and MASP-2 as well as activities of MBL-MASP-1 and MBL-MASP-2 complex were made. Serum samples were taken before conditioning chemotherapy, before HSCT and once weekly after (totally 4-5 samples); in minority of subjects also 1 and/or 3 months post transplantation. The results were compared with data from 267 healthy controls and analyzed in relation to clinical data to explore possible associations with cancer and with chemotherapy-induced medical complications. We found a higher frequency of MBL deficiency-associated genotypes (LXA/O or O/O) among multiple myeloma patients compared with controls. It was however not associated with hospital infections or post-HSCT recovery of leukocytes, but seemed to be associated with the most severe infections during follow-up. Paradoxically, high MBL serum levels were a risk factor for prolonged fever and some infections. The first possible association of MBL2 gene 3'-untranslated region polymorphism with cancer (lymphoma) in Caucasians was noted. Heterozygosity for MASP2 gene +359 A>G mutation was relatively frequent in lymphoma patients who experienced bacteremia during hospital stay. The median concentration of CL-LK was higher in myeloma patients compared with healthy subjects. Chemotherapy induced marked increases in serum MBL and MASP-2 concentrations, prolonged for several weeks and relatively slighter decline in CL-LK level within 1 week. Conflicting findings on the influence of MBL on infections following chemotherapy of myeloma and lymphoma have been reported. Here we found no evidence for an association between MBL deficiency and infection during the short period of neutropenia following conditioning treatment before HSCT. However, we noted a possible protective effect of MBL during follow-up, and suspected that to be fully effective when able to act in combination with phagocytic cells after their recovery. PMID- 30294332 TI - Anti-glucocorticoid-induced Tumor Necrosis Factor-Related Protein (GITR) Therapy Overcomes Radiation-Induced Treg Immunosuppression and Drives Abscopal Effects. AB - Despite the potential to cure metastatic disease, immunotherapy on its own often fails outright or early on due to tumor immune evasion. To address this obstacle, we investigated combinations of anti-GITR, anti-PD1 and radiation therapy (XRT) in our previously developed anti-PD1 resistant 344SQ non-small cell lung adenocarcinoma preclinical tumor model. We hypothesized that targeting multiple mechanisms of immune evasion with this triple therapy would lead to an enhanced tumor-specific immune response and improve survival more so than any mono- or dual therapy. In a two tumor 344SQR murine model, treatment with anti-GITR, anti PD1, and XRT led to significantly improved survival and an abscopal response, with half of the mice becoming tumor free. These mice showed durable response and increased CD4+ and CD8+ effector memory on tumor rechallenge. Regulatory T cells (Tregs) expressed the highest level of GITR at the tumor site and anti-GITR therapy drastically diminished Tregs at the tumor site. Anti-tumor effects were largely dependent on CD4+ T cells and partially dependent on CD8+ T cells. Anti GITR IgG2a demonstrated superior efficacy to anti-GITR IgG1 in driving antitumor effects. Collectively, these results suggest that combinatorial strategies targeting multiple points of tumor immune evasion may lead to a robust and lasting antitumor response. PMID- 30294333 TI - Effect of Soil pH on the Growth, Reproductive Investment and Pollen Allergenicity of Ambrosia artemisiifolia L. AB - Despite the importance of soil reaction for alien plant establishment, few and incomplete studies have included this key factor so far. In this study, we investigated the effects of soil pH on the germination, growth (plant height, width, dry weight, etc.) and reproductive investment (inflorescence size and n degrees of flowers) of Ambrosia artemisiifolia (common ragweed), an allergenic species that is highly invasive and alien in Europe, through a replicated experiment in controlled conditions. In addition, we determined if soil pH has an effect on the total pollen allergenicity of the species. After preliminary germination tests on agar at different pH (from pH4 to pH8), plants were grown in natural soils with pH values of 5 (acid), 6 (sub-acid) and 7 (neutral) obtained by modifying a natural soil by liming methods (calcium hydroxide solution). Results showed that plants grown at pH7 were shorter and developed leaves at a slower rate than those grown at pH5 and pH6; plants grown at pH7 did not produce flowers and pollen. We also observed that, at pH5 and pH6, larger plants (as assessed by the dry weight of the aerial biomass) had both larger and more numerous inflorescences and emitted pollen earlier. Finally, the IgE-binding signal was higher in pollen samples collected from plants grown at pH5 (Integrated Optical Density, IOD, range: 1.12-1.25) than in those grown at pH6 (IOD range: 0.86 -1.03). Although we acknowledge the limitations of only testing the effects of pH in controlled conditions, this study suggests that soil pH greatly affects the growth and development of A. artemisiifolia and indicates that it may have a role in limiting the distribution and hazardousness of this plant. Future field tests should therefore assess the effectiveness of liming in the management and control of ragweed and other alien species. PMID- 30294334 TI - Identification of the Bisabolol Synthase in the Endangered Candeia Tree (Eremanthus erythropappus (DC) McLeisch). AB - Candeia (Eremanthus erythropappus (DC) McLeisch, Asteraceae) is a Brazilian tree, mainly occurring in the cerrado areas. From ethnobotanical information its essential oil is known to have wound healing and nociceptive properties. These properties are ascribed to result from a sesquiterpene alcohol, (-)-alpha bisabolol, which is present at high concentrations in this oil. Bisabolol is highly valued by the cosmetic industry because of its antibacterial, anti inflammatory, skin-smoothing and wound healing properties. Over the past decades, Candeia timber has been collected at large scale for bisabolol extraction from wild reserves and the species is thereby at risk of extinction. To support the development of breeding and nursing practices that would facilitate sustainable cultivation of Candeia, we identified a terpene synthase gene, EeBOS1, that appears to control biosynthesis (-)-alpha-bisabolol in the plant. Expression of this gene in E. coli showed that EeBOS1 protein is capable of producing (-)-alpha bisabolol from farnesyl pyrophosphate in vitro. Analysis of gene expression in different tissues from Candeia plants in different life stages showed a high correlation of EeBOS1 expression and accumulation of (-)-alpha-bisabolol. This work is the first step to unravel the pathway toward (-)-alpha-bisabolol in Candeia, and in the further study of the control of (-)-alpha-bisabolol production. PMID- 30294335 TI - Genome-Wide Association Mapping in a Rice MAGIC Plus Population Detects QTLs and Genes Useful for Biofortification. AB - The development of rice genotypes with micronutrient-dense grains and disease resistance is one of the major priorities in rice improvement programs. We conducted Genome-wide association studies (GWAS) using a Multi-parent Advanced Generation Inter-Cross (MAGIC) Plus population to identify QTLs and SNP markers that could potentially be integrated in biofortification and disease resistance breeding. We evaluated 144 MAGIC Plus lines for agronomic and biofortification traits over two locations for two seasons, while disease resistance was screened for one season in the screen house. X-ray fluorescence technology was used to measure grain Fe and Zn concentrations. Genotyping was carried out by genotype by sequencing and a total of 14,242 SNP markers were used in the association analysis. We used Mixed linear model (MLM) with kinship and detected 57 significant genomic regions with a -log10 (P-value) >= 3.0. The PH 1.1 and Zn 7.1 were consistently identified in all the four environments, ten QTLs qDF 3.1, qDF 6.2 qDF 9.1 qPH 5.1 qGL 3.1, qGW 3.1, qGW 11.1, and qZn 6.2 were detected in two environments, while two major loci qBLB 11.1 and qBLB 5.1 were identified for Bacterial Leaf Blight (BLB) resistance. The associated SNP markers were found to co-locate with known major genes and QTLs such as OsMADS50 for days to flowering, osGA20ox2 for plant height, and GS3 for grain length. Similarly, Xa4 and xa5 genes were identified for BLB resistance and Pi5(t), Pi28(t), and Pi30(t) genes were identified for Blast resistance. A number of metal homeostasis genes OsMTP6, OsNAS3, OsMT2D, OsVIT1, and OsNRAMP7 were co-located with QTLs for Fe and Zn. The marker-trait relationships from Bayesian network analysis showed consistency with the results of GWAS. A number of promising candidate genes reported in our study can be further validated. We identified several QTLs/genes pyramided lines with high grain Zn and acceptable yield potential, which are a good resource for further evaluation to release as varieties as well as for use in breeding programs. PMID- 30294336 TI - Cloning and Characterization of TpNRAMP3, a Metal Transporter From Polish Wheat (Triticum polonicum L.). AB - Essential transition metals and non-essential metals often co-exist in arable soils. In plants, some transition metal transporters, such as the natural resistance-associated macrophage proteins (NRAMPs), poorly selectively transport metals with similar chemical properties whether they are essential or non essential. In this study, a member of the NRAMP transporter family, TpNRAMP3, was identified from dwarf Polish wheat (Triticum polonicum L.). TpNRAMP3 encodes a plasma membrane-localized protein and was highly expressed in leaf blades and roots at the jointing and booting stages, and in the first nodes at the grain filling stage. Expression of TpNRAMP3 increased sensitivity to Cd and Co, but not Zn, and increased the Cd and Co concentrations in yeast. TpNRAMP3 expression in Arabidopsis increased concentrations of Cd, Co, and Mn, but not Fe or Zn, in roots, shoots, and whole plant. However, TpNRAMP3 did not affect translocation of Cd, Co, or Mn from roots to shoots. These results suggest that TpNRAMP3 is a transporter for Cd, Co, and Mn accumulation, but not for Fe or Zn. However, Cd and Co are non-essential toxic metals; selective genetic manipulation of TpNRAMP3 will help breed low Cd- and Co-accumulating cultivars. PMID- 30294338 TI - Overexpression of RsMYB1 Enhances Anthocyanin Accumulation and Heavy Metal Stress Tolerance in Transgenic Petunia. AB - The RsMYB1 transcription factor (TF) controls the regulation of anthocyanin in radishes (Raphanus sativus), and its overexpression in tobacco and petunias strongly enhances anthocyanin production. However, there are no data on the involvement of RsMYB1 in the mechanisms underlying abiotic stress tolerance, despite strong sequence similarity with other MYBs that confer such tolerance. In this study, we used the anthocyanin-enriched transgenic petunia lines PM6 and PM2, which overexpress RsMYB1. The tolerance of these lines to heavy metal stress was investigated by examining several physiological and biochemical factors, and the transcript levels of genes related to metal detoxification and antioxidant activity were quantified. Under normal conditions (control conditions), transgenic petunia plants (T2-PM6 and T2-PM2) expressing RsMYB1, as well as wild type (WT) plants, were able to thrive by producing well-developed broad leaves and regular roots. In contrast, a reduction in plant growth was observed when these plants were exposed to heavy metals (CuSO4, ZnSO4, MnSO4, or K2Cr2O7). However, T2-PM6 and T2-PM2 were found to be more stress tolerant than the WT plants, as indicated by superior results in all analyzed parameters. In addition, RsMYB1 overexpression enhanced the expression of genes related to metal detoxification [glutathione S-transferase (GST) and phytochelatin synthase (PCS)] and antioxidant activity [superoxide dismutase (SOD), catalase (CAT), and peroxidase (POX)]. These results suggest that enhanced expression levels of the above genes can improve metal detoxification activities and antioxidant activity, which are the main components of defense mechanism included in abiotic stress tolerance of petunia. Our findings demonstrate that RsMYB1 has potential as a dual-function gene that can have an impact on the improvement of anthocyanin production and heavy metal stress tolerance in horticultural crops.

AB - Heterotrimeric G protein, composed of Galpha, Gbeta, and Ggamma subunits, modulates plant adaptations to environmental stresses such as high salinity, drought, extreme temperatures and high light intensity. Most of these evidence were however derived solely from conventional genetics methods with which stress associated phenotypes were compared between wild type and various G protein mutant plants. Recent advances in systematic approaches, mainly transcriptome and proteome, have contributed to in-depth understanding of molecular linkages between G proteins and environmental changes. Here, we update our knowledge on the roles of G proteins in abiotic stress responses. Furthermore, we highlight the current whole genome studies and integrated omics approach to better understand the fundamental G protein functions involved in abiotic stress responses. It is our purpose here to bridge the gap between molecular mechanisms in G protein science and stress biology and pave the way toward crop improvement researches in the future. PMID- 30294339 TI - Increased Gibberellins and Light Levels Promotes Cell Wall Thickness and Enhance Lignin Deposition in Xylem Fibers. AB - Light intensity and hormones (gibberellins; GAs) alter plant growth and development. A fine regulation triggered by light and GAs induces changes in stem cell walls (CW). Cross-talk between light-stimulated and GAs-induced processes as well as the phenolic compounds metabolism leads to modifications in lignin formation and deposition on cell walls. How these factors (light and GAs) promote changes in lignin content and composition. In addition, structural changes were evaluated in the stem anatomy of tobacco plants. GA3 was sprayed onto the leaves and paclobutrazol (PAC), a GA biosynthesis inhibitor, via soil, at different irradiance levels. Fluorescence microscopy techniques were applied to detect lignin, and electron microscopy (SEM and TEM) was used to obtain details on cell wall structure. Furthermore, determination of total lignin and monomer contents were analyzed. Both light and GAs induces increased lignin content and CW thickening as well as greater number of fiber-like cells but not tracheary elements. The assays demonstrate that light exerts a role in lignification under GA3 supplementation. In addition, the existence of an exclusive response mechanism to light was detected, that GAs are not able to replace. PMID- 30294340 TI - Cold Hardiness in Trees: A Mini-Review. AB - Significant advances have been made in our understanding of the regulation of cold hardiness. The existence of numerous biophysical and biochemical adaptive mechanisms in perennial woody plants and the complexity their regulation has made the development of methods for managing and improving cold hardiness in perennial woody plants has been very difficult. This may be partially attributed to viewing cold hardiness as a single dimensional response, rather than as a complex phenomenon, involving different mechanisms (avoidance and tolerance), different stages (mid-winter vs. late winter), and having an intimate overlap with the genetic regulation of dormancy. In particular separating the molecular regulation of cold hardiness from growth processes has been challenging. ICE and C-repeat binding factor (CBF), transcription factors (Inducer of CBF expression and CRT binding factor) have been shown to be an important aspect in the regulation of cold-induced gene expression. Evidence has emerged, however, that they are also intimately involved in the regulation of growth, flowering, dormancy, and stomatal development. This evidence includes the presence of CBF binding motifs in genes regulating these processes, or through cross-talk between the pathways that regulate them. Recent changes in climate that have resulted in erratic episodes of unseasonal warming followed by more seasonal patterns of low temperatures has also highlighted the need to better understand the genetic and molecular regulation of deacclimation, a topic of research that is only more recently being addressed. Environmentally-induced epigenetic regulation of stress responses and seasonal processes such as cold acclimation, deacclimation, and dormancy have been documented but are still poorly understood. Advances in the ability to efficiently generate large DNA and RNA datasets and genetic transformation technologies have greatly increased our ability to explore the regulation of gene expression and explore genetic diversity. Greater knowledge of the interplay between epigenetic and genetic regulation of cold hardiness, along with the application of advanced genetic analyses, such as genome-wide association-studies (GWAS), are needed to develop strategies for addressing the complex processes associated with cold hardiness in woody plants. A cautionary note is also indicated regarding the time-scale needed to examine and interpret plant response to freezing temperatures if progress is to be made in developing effective approaches for manipulating and improving cold hardiness.

AB - PIWI-LIKE 2, a member of the ARGONAUTE protein family, is exclusively expressed in pre-pachytene and pachytene stages of spermatogenesis. PIWI-LIKE 2 acts in the germ cell development and the silencing of retrotransponsons to maintain the genomic integrity and stem cell character. In the present study we investigated DNA methylation as potential mechanism for the regulation of human PIWI-LIKE 2 expression in cell lines related to spermatozoa precursor cells. We detected a high methylation of the PIWI-LIKE 2 promoter in TCam-2 cells, while in NT2/D1 cells the promoter was hypomethylated. Concordantly, PIWI-LIKE 2 expression is higher in NT2/D1 cells than in TCam-2 cells. By demethylation of the promoter with 5'-Aza-2'-deoxycytidine, PIWI-LIKE 2 expression in TCam-2 was increased, while in NT2/D1 no alterations in PIWI-LIKE 2 expression could be detected. In conclusion, we analyzed the DNA methylation driving PIWI-LIKE 2 expression in undifferentiated germ cell tumors and demonstrated an epigenetic basis for PIWI LIKE 2 expression in this cell type. PMID- 30294342 TI - Lead Modulates trans- and cis-Expression Quantitative Trait Loci (eQTLs) in Drosophila melanogaster Heads. AB - Lead exposure has long been one of the most important topics in global public health because it is a potent developmental neurotoxin. Here, an eQTL analysis, which is the genome-wide association analysis of genetic variants with gene expression, was performed. In this analysis, the male heads of 79 Drosophila melanogaster inbred lines from Drosophila Synthetic Population Resource (DSPR) were treated with or without developmental exposure, from hatching to adults, to 250 MUM lead acetate [Pb(C2H3O2)2]. The goal was to identify genomic intervals that influence the gene-expression response to lead. After detecting 1798 cis eQTLs and performing an initial trans-eQTL analysis, we focused our analysis on lead-sensitive "trans-eQTL hotspots," defined as genomic regions that are associated with a cluster of genes in a lead-dependent manner. We noticed that the genes associated with one of the 14 detected trans-eQTL hotspots, Chr 2L: 6,250,000 could be roughly divided into two groups based on their differential expression profile patterns and different categories of function. This trans-eQTL hotspot validates one identified in a previous study using different recombinant inbred lines. The expression of all the associated genes in the trans-eQTL hotspot was visualized with hierarchical clustering analysis. Besides the overall expression profile patterns, the heatmap displayed the segregation of differential parental genetic contributions. This suggested that trans-regulatory regions with different genetic contributions from the parental lines have significantly different expression changes after lead exposure. We believe this study confirms our earlier study, and provides important insights to unravel the genetic variation in lead susceptibility in Drosophila model. PMID- 30294343 TI - Identification and Functional Analysis of Two New Mutant BnFAD2 Alleles That Confer Elevated Oleic Acid Content in Rapeseed. AB - Rapeseed (Brassica napus L.) is a vital oil crop worldwide. High oleic acid content is a desirable quality trait for rapeseed oil, which makes it more beneficial to human health. However, many germplasm resources with high oleic acid content in rapeseed have not been evaluated with regard to their genotypes, making it difficult to select the best strains with this trait for the breeding of high oleic acid rapeseed variety. This work was to explore the gene-regulation mechanism of this trait using a new super-high oleic acid content (~85%) line N1379T as genetic material. In this study, the sequences of four homologous fatty acid desaturase (BnFAD2) genes were compared between super-high (~85%, N1379T) and normal (~63%) oleic acid content lines. Results showed that there were two single-nucleotide polymorphisms (SNPs) in BnFAD2-1 and BnFAD2-2, respectively, which led to the amino acid changes (E106K and G303E) in the corresponding proteins. Functional analysis of both genes in yeast confirmed that these SNPs were loss-of-function mutations, thus limiting the conversion of oleic acid to linoleic acid and resulting in the considerable accumulation of oleic acid. Moreover, two specific cleaved amplified polymorphic sequences (CAPS) markers for the two SNPs were developed to identify genotypes of each line in the F2 and BC1 populations. Furthermore, these two mutant loci of BnFAD2-1 and BnFAD2-2 genes were positively associated with elevated oleic acid levels and had a similar effect with regard to the increase of oleic acid content. Taken together, these two novel SNPs in two different BnFAD2 genes jointly regulated the high oleic acid trait in this special germplasm. The study provided insight into the genetic regulation involved in oleic acid accumulation and highlighted the use of new alleles of BnFAD2-1 and BnFAD2-2 in breeding high oleic acid rapeseed varieties. PMID- 30294344 TI - Taxonomically Restricted Genes Are Fundamental to Biology and Evolution. AB - Genes limited to particular clades, taxonomically restricted genes (TRGs), are common in all sequenced genomes. TRGs have recently become associated with the evolution of novelty, as numerous studies across the tree of life have now linked expression of TRGs with novel phenotypes. However, TRGs that underlie ancient lineage specific traits have been largely omitted from discussions of the general importance of TRGs. Here it is argued that when all TRGs are considered, it is apparent that TRGs are fundamental to biology and evolution and likely play many complementary roles to the better understood toolkit genes. Genes underlying photosynthesis and skeletons, for example, are examples of commonplace fundamental TRGs. Essentially, although basic cell biology has a highly conserved genetic basis across the tree of life, most major clades also have lineage specific traits central to their biology and these traits are often based on TRGs. In short, toolkit genes underlie what is conserved across organisms, while TRGs define in many cases what is unique. An appreciation of the importance of TRGs will improve our understanding of evolution by triggering the study of neglected topics in which TRGs are of paramount importance. PMID- 30294345 TI - Applicability of a shortened interpretation model for intraoperative parathyroid hormone monitoring in patients with primary hyperparathyroidism in an endemic goiter region. AB - Background: In primary hyperparathyroidism (pHPT), quick intraoperative parathyroid hormone monitoring (IOPTH) is performed to predict complete excision of hyperfunctioning tissue and therefore cure. In recent years, efforts have been made to make this prediction more accurate and to shorten the duration of the test, respectively, and therefore reduce waiting and total operating time. The aim of this study was to evaluate the practicability and safety of a time-reduced criterion (decline >= 35% after 5 min) in a large cohort of patients. Methods: In an 11-year period, all patients operated for pHPT were analyzed. After preoperative localization studies, hyperfunctioning parathyroid tissue was removed and IOPTH monitoring was performed. Intraoperatively, a decline of >=50% from baseline 10 min after excision of the gland predicted cure. The performance of an interpretation model, using an earlier PTH level was analyzed retrospectively (decline >= 35% from baseline 5 min after excision). Differences in sensitivity, specificity, positive/negative predictive value and accuracy were calculated. Results: According to the inclusion criteria, 1018 patients were analyzed. IOPTH predicted cure in 854 patients (83.9%) 10 min after gland excision with a false positive decline in 13 patients (1.5%). Applying the modified criterion (>=35% decline within 5 min), 814 patients (80%) showed an appropriate decline (false positive in 18 [2.2%]). Overall, multiple gland disease would have been missed in 7 patients. McNemar's test showed a significantly lower sensitivity, specificity and accuracy applying the "35%" criterion. Conclusions: In an endemic goiter region, a criterion, demanding a >= 35% decline 5 min after excision can not be recommended for IOPTH monitoring in patients with pHPT. PMID- 30294346 TI - Is there any relationship between human foamy virus infections and familial Mediterranean fever? AB - Background: Familial Mediterranean fever (FMF) is generally defined as an autosomal recessive disease, characterized by the automatic activation of the innate immune system in the absence of a detectable pathogenic stimulant. We hypothesize that the pathogenic factors, besides the genetic causes, may affect the development of FMF symptoms. To test this hypothesis, we examined the effects of human foamy virus (HFV) positivity on the occurrence of the clinical symptoms of FMF. Materials and Methods: Two hundred and twenty-two FMF patients with definitive diagnosis according to Tel Hashomer criteria (study group 1 [SG1]), 205 symptomatic FMF patients who had definitive diagnosis according to the same criteria but did not carry any of the 12 most commonly occurring MEFV gene mutations (study group 2 [SG2]), and 200 healthy individuals were included as control group (study group 3 [SG3]) in the study. The genetic analysis was applied in the Molecular Genetics Laboratory of the Department of Medical Biology, Faculty of Medicine, Ondokuz Mayis University. This study was designed as a case-control study. HFV positivity was tested by amplifying the HFV bel1 gene sequence with polymerase chain reaction technique. Statistical analyses were conducted using SPSS version 23.0 software. Results: HFV positivity showed significant differences between the study groups (P = 0.002). While 43 (19.02%) of the 222 SG1 patients were positive for the HFV bel1 gene sequence, 33 (16.09%) of the 205 SG2 patients were positive for the same sequence. Only 15 (7.5%) of the SG3 participants were positive for the presence of HFV bel1 gene sequence. Conclusion: The results of our study suggested that HFV positivity can be a stimulant pathogenic factor of natural immune system which can cause the emergence of FMF symptoms. PMID- 30294347 TI - High seroprevalence of anti-Helicobacter pylori antibodies in patients with ventilator-associated pneumonia. AB - Background: The pathogenesis of ventilator-associated pneumonia (VAP) is not clearly known. Recently, the role of gastric bacterial colonization has been proposed. The role of gastric colonization with Helicobacter pylori in pathogenesis of VAP was determined by comparing the prevalence of H. pylori in patients with VAP and control participants. Materials and Methods: One hundred and eighteen mechanically ventilated patients were divided into two groups; 59 participants with VAP and 59 without VAP. Serologic tests for H. pylori were registered. Results: Mean age in seropositive patients was significantly higher. About 71.2% in VAP group and 61.01% in controls were IgG seropositive (P = 0.24). IgM seropositivity was 23.73% versus 8.47% in VAPs and controls, respectively (P = 0.024). By increasing the time of intubation, more patients became seropositive for IgM (Pearson's correlation coefficient = 0.4, P = 0.002). Conclusion: IgM seropositivity and serum levels were significantly higher in VAP patients. Furthermore, by increasing the duration of intubation, serum levels for IgM increased significantly. PMID- 30294348 TI - Cancer trends in a province of Southwest of Iran, 2003-2016. AB - Background: Awareness of the trends of cancer incidence in each geographic region is an important. The aim of present study was to determine the incidence trends of cancer in Chaharmahal and Bakhtiari (Ch and B) province in Southwest of Iran. Materials and Methods: In this secondary data analysis, retrospective existing data were used from cancer registry reports in Ch and B in Southwest of Iran in 2003-2016. Data on epidemiologic trend were analyzed using Joinpoint software package and annual percentage change (APC) with 95% confidence interval (95% CI) was computed. Results: Age-standardized incidence rate per 100,000 persons in the province in 2003 was 31.74 that increased to 147.14 in 2016. APC during 2003-2016 was 12.58% (CI: 9.3-16) and significant, which was 10.22% (7.4-13.1) and 14.47% (10.2-18.9) in men and women, respectively. Incidence of the stomach, breast, colorectal, thyroid, lymph node, and ovarian cancers is increasing and the highest incidence was observed in two age groups of 25-34 and 55-64 years. Conclusion: In general, cancers are of increasing trend. Surveillance and monitoring the incidence of cancer and studying the causes of environmental or genetic in the cancer changes can help for cancer prevention and control. PMID- 30294349 TI - Effect of extracorporeal shock wave therapy on improving burn scar in patients with burnt extremities in Isfahan, Iran. AB - Background: Pathologic scarring is a common problem after burn injury that has functional and esthetic limitations. Conservative and surgical treatments available for these scars are not always satisfactory. Extracorporeal shock wave therapy (ESWT) is a noninvasive modality that has proven positive effects on burn scars and wound healing in few studies. This study was conducted to evaluate the effects of ESWT on improving burn scar in extremities. Materials and Methods: This study was a prospective quasi-experimental on burn patients with burn scar in their extremities that underwent ESWT sessions once a week for 6 weeks. For evaluating pain and itching, visual analog scale (VAS) and for scar appearance, Vancouver Scar Scale (VSS) were used. These scales were measured and compared at the beginning of the treatment, at the end of the treatment, and 1 and 3 months after the end of the intervention. Results: In this study, 17 patients were treated with ESWT with a mean age of 37.94 +/- 7.25 years that 47.1% of them were male. The mean of VAS score for pain and itching and VSS score were decreased significantly after the treatment and during follow-ups (All P < 0.001). Conclusion: ESWT can improve the pain, itching, and appearance of the burn scar in human extremities in burn patients. PMID- 30294350 TI - The prognostic values of beta-2 microglobulin for risks of cardiovascular events and mortality in the elderly patients with isolated systolic hypertension. AB - Background: The present study aimed to investigate the effects of serum beta-2 microglobulin (B2M) on the risks of major cardiovascular events (MACEs) and all cause death in Chinese elderly isolated systolic hypertension (ISH) patients without severe renal insufficiency (estimated glomerular filtration rate [eGFR] <30 ml/min/1.73 m2). Materials and Methods: Serum B2M concentration, creatinine eGFR, and blood pressure variability were evaluated in 460 elderly patients (mean age, 82.6 years; 28 women) with ISH in this observational study. The Cox proportional hazard model was adopted to calculate adjusted hazard ratios (HRs) of risk factors for cardiovascular events and all-cause deaths. Results: During a median follow-up period of 37.6 months, 63 patients (13.7%) died, and 65 patients (14.1%) had MACEs. Multivariable analysis showed that the higher serum B2M concentration (B2M >=0.28 mg/dl) was an independent predictor of increased risk of MACEs (nonfatal acute myocardial infarction, acute heart failure, ischemic stroke, and cardiovascular deaths) and all-cause death (HR: 2.62, 95% confidence interval [CI]: 1.46-4.69, P = 0.001 and HR: 3.40, 95% CI: 1.78-6.48, P < 0.001, respectively) adjusting for other multiple confounders including creatinine-eGFR and cystatin C. In addition, blood pressure variability derived from ambulatory blood pressure measurement was not associated with incidence of MACEs and all cause mortality (P > 0.05). Conclusion: Our data suggest that serum B2M concentration may be individually associated with MACEs and all-cause death in elderly ISH patients without severe renal insufficiency even after adjusted for creatinine-eGFR and cystatin C. PMID- 30294351 TI - G6PD deficiency and aluminum phosphide poisoning. AB - Aluminum phosphide (ALP) poisoning is one of the fatal poisonings in the world. Hemolysis is a rare presentation of this poisoning. Here, we report an episode of hemolysis due to G6PD deficiency after ingestion of ALP and also the patient survived. PMID- 30294352 TI - One-anastomosis gastric bypass as an alternative procedure of choice in morbidly obese patients. AB - One-anastomosis gastric bypass is an attractive bariatric procedure. It is effective in weight loss and comorbidity resolution. It is a relatively simple and fast operation with low complication rates that make it a suitable option in super-obese individuals. Although not proven yet, there are some concerns about its long-term safety profile in terms of biliary reflux, marginal ulcer, and esophagogastric malignancy. In this article, we review the technique of this procedure and discuss about some practical surgical highlights. Furthermore, we overview studies performed about this procedure and compare it to some other well established bariatric operations, while providing a detailed study about the facts related to its outcomes and complications. PMID- 30294353 TI - Changes in the hemoglobin level after one unit of packed red blood cell transfusion in Intensive Care Unit patients. AB - Background: Blood transfusion is essential in severely ill patients whose hemoglobin (Hb) levels are low, but there are some factors that inhibit optimal increase in Hb. The aim of this study was to evaluate the amount of increase in Hb levels after packed red blood cell (PRBC) transfusions in the Intensive Care Unit (ICU) patients and its related factors. Materials and Methods: This cross sectional study included 124 patients admitted to the ICU, and needed PRBC transfusion. Demographic information, Hb on the 1st day of admission, blood volume transfusions during the 7 days, and the 7th day of admission Hb level were extracted from patients' records. Results: The average initial Hb level of patients was reported as 6.17 +/- 1.43 g/dl, and after administrating PRBC (4.23 +/- 1.87 units during 7 days), the Hb level was 8.09 +/- 1.66 g/dl after 7 days (mean difference was 1.91 +/- 1.93, t = 11.06, P < 0.001). No significant differences were found between change in Hb level in the terms of age, gender, underlying illness, body mass index, hospitalization history, fever, and duration of hospitalization (P > 0.05). However, the mean increased Hb level in hospitalized patients with internal disorders was the lowest (0.25 g/dl, P = 0.002). Conclusion: The results of our study showed that the increased Hb level based on one unit of received PRBC was low, especially in patients with internal. Therefore, based on high frequency of anemia in ICU patients and relative complications, physicians should pay attention to factors affecting Hb levels after PRBC transfusion such as medical history. PMID- 30294354 TI - The Papanicolaou Society of Cytopathology guidelines for respiratory cytology: Reproducibility of categories among observers. AB - Introduction: The Papanicolaou Society of Cytopathology (PSC) has developed a set of guidelines for reporting respiratory cytology. While the malignancy risk for each category is known, the interobserver reproducibility of these diagnostic categories has not been well described. Methods: Fifty-five cytologic specimens obtained by fine needle aspiration from the pulmonary nodules were independently reviewed by four board-certified cytopathologists and assigned to the diagnostic categories described by the PSC guidelines for respiratory specimens. Statistical analysis for diagnostic accuracy was performed for absolute agreement and chance corrected agreement (kappa). Differences in frequency of distribution of diagnoses between raters were assessed using the Kruskal-Wallis test. Results: No significant differences in distribution of scores by raters were observed. On average, the absolute agreement was 49.5% and the chance-corrected agreement (kappa) was 20%. 34.5% of interrater comparisons were in full agreement, and total lack of agreement between the four categories was found in 3% of cases. Combining the "suspicious for malignancy" category with the "malignant" category did not significantly alter interrater agreement statistics. Conclusions: The PSC categories showed only fair reproducibility among four cytopathologists. Agreement between raters was at best fair and did not improve significantly when the categories "suspicious for malignancy" and "malignant" were combined. The most common source of disagreement appeared to be between the categories "suspicious" and "malignant." PMID- 30294355 TI - Not all neck mass fine-needle aspirations with squamous cells are squamous cell carcinoma; report of a case of recurrent thyroid carcinoma with papillary and squamous components. AB - We report a case of a 65-year-old female who had a total thyroidectomy 12 years ago for papillary thyroid carcinoma (PTC) who presented with a recurrent thyroid bed mass. Fine-needle aspiration biopsy yielded malignant cells, consistent with squamous cell carcinoma (SCCa). Surgical resection was performed, and histologic evaluation of the mass showed mixed PTC and SCCa. The tumor cells were positive for BRAF V600E mutation. Thyroid carcinomas with admixed papillary carcinoma and SCCa are rare and are associated with aggressive behavior, high rates of metastasis, and poor outcomes. Although SCCa presenting as a neck mass is relatively common, clinical history and appropriate workup are essential for accurate diagnosis and determination of origin. PMID- 30294356 TI - Personality Traits in Fibromyalgia (FM): Does FM Personality Exists? A Systematic Review. AB - Introduction: Fibromyalgia (FM) is the second most common rheumatic disease with many effects on patient's quality of life. It has been described as a chronic condition characterized by widespread musculo-skeletal pain, sleep disorders and prominent fatigue. Regarding the role of personality factors in fibromyalgia, researchers have focused both on personality traits and psychopathological aspects showing inconsistent results. In particular, several studies have examined the role of alexithymia in FM patients, a trait of personality characterized by difficulty in identification, recognition and description of emotions and feelings, while others have focused on a specific type of personality, such as type D personality (distressed personality). Other studies investigated personality in FM patients referring to Cloninger's model, a psychobiological model of personality that includes both temperamental and character dimensions of personality. Analyzing scientific literature on this subject seems well suited to provide a critical review of the latest studies and their results. Methods: The method used for this review satisfies the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). We identified PsycInfo and PubMed as databases for our research. Results: Personality is studied under many aspects and a reference model is not always present. Many studies underline high levels of alexithymia and type D personality in FM patients but when depression is controlled, these results do not differ from those of healthy controls. Conclusion: Studies that use a comprehensive model of personality present a different theoretical approach and use alternatively the Big-Five model, Eysenck's and Cloninger's models. The use of a comprehensive model of personality and the control of psychopathological disorders, such as anxiety and depression, seem to be very relevant for a better understanding of a specific personality profile associated with fibromyalgia. PMID- 30294357 TI - Exploring the Role of Sedentary Behavior and Physical Activity in Depression and Anxiety Symptom Severity among Patients with Substance Use Disorders. AB - Research has consistently shown that regular physical activity may protect against the development and maintenance of depression and anxiety, whereas sedentary behavior may exacerbate depression and anxiety. However, much of the past research in this area has focused on non-clinical populations. Therefore, the goal of this study was to examine the relations of physical activity and sedentary behavior to depression and anxiety symptom severity among an understudied patient population, patients in residential substance use disorder (SUD) treatment. This study also sought to determine the extent to which physical activity and sedentary behavior relate to depression and anxiety symptom severity above and beyond an established transdiagnostic risk factor for depression and anxiety, emotion dysregulation. A sample of 41 patients from a residential SUD treatment facility completed a variety of self-report measures focused on physical activity, sedentary behavior, emotion dysregulation, and depression and anxiety symptom severity. Physical activity, but not sedentary behavior, was found to significantly predict depression symptom severity above and beyond emotion dysregulation. Physical activity and sedentary behavior did not significantly predict anxiety symptom severity above and beyond emotion dysregulation. In addition to providing additional support for the relevance of emotion dysregulation to depression and anxiety symptom severity, results suggest that physical activity may be another factor to consider in evaluating risk for depression among patients with SUDs. Although additional research in this area is warranted, results also suggest the potential utility of targeting physical activity in reducing risk for depression among patients with SUDs. PMID- 30294358 TI - Empirical Evaluation of a Conceptual Model for the Perceived Value of Health Services. AB - Introduction: Perceived value and its antecedents and consequences have been claimed to be important in industries with higher customer involvement. The aim of this paper is therefore to empirically assess the conceptual model, with perceived service value as its central component. It also investigates how it affects loyalty and satisfaction, how it is influenced by its antecedents, and to compare with other studies investigating partial relationship between variables. Methods: A total of 800 patients were enrolled in the main study, and the data was analysed using exploratory and confirmatory factor analyses. By modelling linear structural equations, we assessed reliability and established the convergent and discriminant validity of the questionnaire in the same way as in the pilot study. Results: In the conceptual model for testing our hypotheses, we also included the relationship between patient satisfaction and loyalty. In this manner, the fitting of data to the model was significantly improved. After including the additional relationship, global fit indices had the following values: Chi-square=349.6 (sig.=0.00), df=143, RMSEA=0.05, NFI=0.96, CFI=0.97. All relationships between the constructs were statistically significant, thus confirming all our hypotheses. Conclusions: The major conclusion of this paper is that an especially higher reputation and higher perceived service quality can contribute to perceived service value and therefore to more satisfied patients. The research approach has a few limitations. In the future, the model of perceived service value can be extended with variables such as emotions, patient trust, and commitment as well. PMID- 30294359 TI - Outpatient Antibiotic Consumption for Urinary Infections in Croatia 2005 - 2014: What can be Learned from Utilization Trends. AB - Aim: The aim of this study was to determine quantities of antibiotics used mainly or exclusively for urinary tract infections in Croatia between 2005 and 2014, to describe utilisation trends, and general consequences of antibiotic consumption on antimicrobial resistance. Methods: Antibiotic utilisation data were obtained from annual reports of both the Croatian Drug Agency and Croatian Academy of Medical Sciences. Antibiotic consumption was expressed in DDD/1000 inhabitants/day (DDD TID). Antimicrobial resistance was analysed for E. coli, E. faecalis, E. faecium, P. aeruginosa, Klebsiella spp., P. mirabilis. Descriptive statistics were used to process data and calculate trends. Results: Overall, utilisation of antibacterials decreased by 4.8% (from 3,35 to 3,19 DDD TID), while trends of individual agents varied substantially - from 87% decline for ceftibuten to 160% rise for levofloxacin. The consumption of quinolones increased by 32.3%. This was mostly due to increased ciprofloxacin consumption (144% raise). Sulfamethoxazole-trimethoprim declined by 57%, while nitrofurantoin increased by 86%. The use of fosfomycin was marginal. Antimicrobial resistance of E. coli increased against quinolones by 54.5%, and against nitrofurantoin by 2 3%. Quinolone resistance of other pathogens (Klebiella spp, Proteus mirabilis), increased variably - between 17.2% (Klebsiella) and 90% (Proteus), while for P. aeruginosa remained the same at 22%. Conclusion: High rates of antimicrobial utilisation require prescribing restrictions and educational interventions. The increased use of fluoroquinolones is a potentially serious public health threat due to the rapid development of resistance among uropathogens. This threat can be avoided by greater use of nitrofurantoin and fosfomycin. PMID- 30294360 TI - Work-Related Stress Factors in Nurses at Slovenian Hospitals - A Cross-sectional Study. AB - Background: Surveys conducted among healthcare workers revealed that nursing staff often face various stressors associated with occupational activities, which reduce their work efficiency. The aim of the study was to establish the level of stress in nurses working at hospitals in Slovenia and to identify stress-related factors. Methods: A cross-sectional epidemiological design and a standardized instrument called the "Nursing stress scale" were used. The sample included 983 nurses from 21 Slovenian hospitals. The research was conducted in 2016. Results: Prevalence of high level of stress was 56.5% of respondents (M (median)=75). Prevalence of high level of stress and stress factors may be statistically significant attributable to dissatisfaction at work (p<0.001), disturbing factors at work (p<0.001), inability to take time off in lieu after working on weekend (p=0.003), shorter serving (p=0.009), fixed-term work (p=0.007), and an increased number of workdays on Sunday (p=0.030). Conclusion: The stress rate and stress factors are substantially influenced by variables reflecting work organization, competences and skills of healthcare management to work with people. Results reflect the need for nursing management and policy makers to design strategies to ensure adequate staffing, efficient organization and an encouraging work environment. PMID- 30294361 TI - Validation of the Slovenian Version of Motor Imagery Questionnaire 3 (MIQ-3): Promising Tool in Modern Comprehensive Rehabilitation Practice. AB - Purpose: The high rate of injury incidence and its severity is estimated to cause approximately 9% of global mortality, while a large proportion of people surviving their injuries experience temporary or permanent disabilities. To reduce the occurrence of disability and improve general health of survivors, a more comprehensive rehabilitation approach is needed. Motor imagery is recognized as the promising cognitive strategy to counteract impaired functional capacity of the neuromuscular system. Thus, we aimed to provide to the Slovenian-speaking community a valid and reliable version of Motor Imagery Questionnaire - 3 [MIQ 3], that consists of kinaesthetic imagery [KI] and visual [i.e., Internal Imagery [IMI] and external imagery [EVI]] items. Methods: We investigated both absolute and relative test-retest repeatability; construct validity and internal consistency of the KI, IMI and EMI items of the Slovenian version of MIQ-3 in 86 healthy adult subjects. Results: Results showed high to very high average intra class correlation coefficient [ICC] for the visual items [ICC=0.89] and KI items [ICC=0.92], whilst the measure of absolute variability presented as coefficient of variation [CV%] ranged from 4.9% [EVI] to 6.7% [KI]. The internal consistency was satisfactory [Cronbach alpha=0.91 [KI] and 0.89]) for both visual items. Confirmatory analysis confirmed a two-factorial structure of MIQ-3. Conclusion: Understanding the content of the questionnaire is of utmost importance to ensure its effectiveness in rehabilitation practice. The Slovenian translation of the MIQ-3 is culturally and linguistically equivalent to the original English version. PMID- 30294362 TI - Surgical Site Infections in Slovenian Acute Care Hospitals: Surveillance Results, 2013-2016. AB - Introduction: The objective was to present the results of the Slovenian National surgical site infections (SSIs) surveillance system from 2013 to 2016 and to compare them to the reference data for the European Union (EU) and European Economic Area (EEA) countries. Methods: Surveillance was conducted according to the Slovenian protocol consistent with the European Centre for Disease Prevention and Control protocol. Descriptive analyses were performed. Results: Data were collected for 1080 patients of whom 57.4% were patients with cholecystectomy (from three hospitals), 29.0% with caesarean sections (from four hospitals) and 4.7%, 4.5% and 4.4% patients with hip prosthesis, knee prosthesis and colon surgery (each surgical category from one hospital). The pooled in-hospital SSI incidence density for caesarean section was 3.7 (95% CI: 1.4-8.1; inter-hospital range: 0.0-11.5) and for cholecystectomy 6.8 (95% CI: 3.5-11.9; inter-hospital range: 4.1-11.9) per 1000 post-operative patient-days. The in-hospital SSI incidence density for colon surgery was 24.8 (95% CI: 12.5-44.0) and for hip prosthesis 2.6 (95% CI: 0.1-14.2) per 1000 post-operative patient-days. No SSIs were reported among the 49 patients with knee prostheses. Conclusions: The estimated SSIs incidence rates varied between different surgical categories and the different participating hospitals. In some of the participating hospitals and for some of the surgical procedures under surveillance they were rather high in comparison to the reference data for hospitals from EU/EEA countries. It is urgent to expand standardised SSIs surveillance to all Slovenian acute care hospitals with surgical wards to contribute to evidence-based SSIs prevention and control in Slovenia. PMID- 30294363 TI - Correlation between the DAI and ICON Indices used for Assessment of Orthodontic Treatment need in Croatian Schoolchildren. AB - Introduction: The aims were: evaluation of the correlation between the Dental Aesthetic Index (DAI) and Index of Complexity, Outcome and Need (ICON); the assessment of orthodontic treatment need for schoolchildren in a population with two indices, separately for schoolchildren with mixed and permanent dentition; the estimation of the population share that could not receive orthodontic treatment because of the presence of caries and/or gingivitis. Methods: A total of 2652 Zagreb school children (7 - 19 years old, 52.4% of them were females) completed a questionnaire regarding previous orthodontic treatment and the type of appliance used. Their oral cavity was also inspected. The DAI and ICON indices were used for the assessment of malocclusion prevalence. Results: The subjects with mixed dentition had a greater need for orthodontic treatment, when compared to subjects with permanent dentition, when using the DAI index (p<0.001). When using the ICON index, 11.7% of subjects with mixed dentition had very severe malocclusion, as opposed to 5.8% of subjects with permanent dentition. The DAI and ICON scores correlated positively linearly (r=0.521; p<0.001). A higher prevalence of both gingivitis and caries was recorded more often in boys; caries more often in the group with the mixed dentition, and gingivitis in the group with permanent dentition (p<0.05). Conclusion: The DAI and ICON indices have moderate agreement in assessment of malocclusion severity scores. One third of all schoolchildren with various degrees of both ICON and DAI indices have gingivitis, and half of them have caries. PMID- 30294364 TI - Analysis of 22 Years of Surveillance for Prion Diseases in Slovenia, 1996 to 2017. AB - Introduction: The objective was to present the results of surveillance of prion diseases in Slovenia that was established in 1996 and then to assess the interdisciplinary approach according to the algorithm of case management and reporting data to the National Register at the National Institute of Public Health. Methods: A descriptive study of Creutzfeldt-Jakob disease (CJD) recorded in the period from 1996 to 2017 was carried out. Results: A total of 123 cases of prion disease were notified between 1996 and 2017. Out of these, 68 were recorded and confirmed by autopsy as sporadic CJD with an average incidence rate of 1,5 cases per million population per year. In one case a gene analysis showed mutation E200K in prion protein gene, PRNP. Two cases of the Gerstman-Straussler Scheinker syndrome and one clinical case of fatal insomnia with new PRNP mutation, N181S, were notified. Diagnostic value of protein 14-3-3 analysis in the liquor reached 82% sensitivity and 71% specificity. 25 cases of notified clinically possible/probable CJD were disproved after autopsy. In eleven notified possible CJD cases the autopsy had not been performed. Variant CJD has not yet been proven in Slovenia. Conclusion: Incidence rates were comparable with other European countries. Completeness of reporting and proper management of CJD cases according to the algorithm of reporting, management and case confirmation would need some improvement. A well-functioning surveillance system, including timely notifications, would enable an appropriate epidemiological investigation and an effective response to public health risks, thus the awareness of prion diseases should not decline. PMID- 30294365 TI - Selective dorsal rhizotomy in ambulant children with cerebral palsy. AB - Background: Selective dorsal rhizotomy (SDR) is a surgical procedure for treating spasticity in ambulant children with cerebral palsy (CP). However, controversies remain regarding indications, techniques and outcomes. Current evidence summary: Because SDR is an irreversible procedure, careful patient selection, a multi disciplinary approach in assessment and management and division of the appropriate proportion of dorsal rootlets are felt to be paramount for maximizing safety. Reliable evidence exists that SDR consistently reduces spasticity, in a predictable manner and to a substantial degree. However, functional improvements are small in the short-term with long-term benefits difficult to assess. Future outlook: There is a need for high-quality studies utilizing long-term functional outcomes and well-matched control groups. Collaborative, multicentre efforts are required to further define the role of SDR as part of the management paradigm in maximizing physical function in spastic CP. PMID- 30294366 TI - Trends in slipped capital femoral epiphysis: is the rate declining? AB - Purpose: Slipped capital femoral epiphysis (SCFE) is an adolescent hip condition with a high risk of complication. The purpose of this study was to evaluate trends in treatment using a prospectively collected paediatric nationally representative database. Methods: A total of 9034 patients undergoing treatment for idiopathic SCFE were selected by querying the Healthcare Cost and Utilization Project's Kids' Inpatient Database for the years 1997, 2000, 2003, 2006, 2009 and 2012. The selected patients were separated based on operative approach and these cohorts were analyzed based on temporal and categorical differences in operative approach, patient demographics and clinical characteristics. Univariate and multivariate analyses were used when appropriate and the Mantel-Haenszel test for trend was used in temporal analysis. Results: Overall SCFE procedures have decreased 27.5% (p < 0.001). Closed procedures have decreased 28.5% (p < 0.001), while open procedures have decreased 44.8% (p < 0.001). Bilateral closed procedures have increased 7.2% (p < 0.001). The ratio of open to closed procedures decreased in patients aged nine to 12 years and increased in patients aged 13 to 16 years (p < 0.001). Conclusion: Here we report age stratified trends in treatment for idiopathic SCFE using nationally representative data and show an overall decrease in admissions and procedures over time. Level of Evidence: Level III, retrospective comparison study. PMID- 30294367 TI - Outcomes after slipped capital femoral epiphysis: a population-based study with three-year follow-up. AB - Purpose: To evaluate outcomes three years after treatment for slipped capital femoral epiphysis (SCFE): development of avascular necrosis (AVN), subsequent surgery, hip function and the contralateral hip. Methods: This prospective cohort study included a total national population of 379 children treated for SCFE between 2007 and 2013. A total of 449 hips treated for SCFE and 151 hips treated with a prophylactic fixation were identified. The Barnhoft questionnaire, a valid patient-reported outcome measure (PROM), was used. Results: In all, 90 hips had a severe slip, 61 of these were clinically unstable. AVN developed in 25 of the 449 hips. Six of 15 hips treated with capital realignment developed AVN. A peri implant femur fracture occurred in three slipped hips and in two prophylactically pinned hips. In three of these five hips technical difficulties during surgery was identified. In 43 of 201 hips scheduled for regular follow-up a subsequent SCFE developed in the contralateral hip. Implant extraction after physeal closure was performed in 156 of 449 hips treated for SCFE and in 51 of 151 prophylactically fixed hips. Children with impaired hip function could be identified using the Barnhoft questionnaire. Conclusion: Fixation in situ is justified to remain as the primary treatment of choice in SCFE. Overweight is more common in children with SCFE than in the average population. Prophylactic fixation is a safe procedure when performed using a correct technique. The number of patients who developed AVN after capital realignment is of concern. We recommend rigorous follow-up of both hips, including PROM evaluation, until physeal closure. Level of Evidence: II - prospective cohort study. PMID- 30294368 TI - Acetabular morphology in slipped capital femoral epiphysis: comparison at treatment onset and skeletal maturity. AB - Purpose: To investigate changes in acetabular morphology during the follow-up of slipped capital femoral epiphysis (SCFE) and search for factors associated with acetabular dysplasia at skeletal maturity. Methods: We evaluated 108 patients with unilateral SCFE (mean age at slip, 12.3 years sd 1.7) to skeletal maturity, with a minimum follow-up of two years (median 4.5 years; interquartile range 3.2 to 6.2). Acetabular parameters obtained from initial and most recent radiographs included the lateral centre-edge angle (LCEA), Tonnis angle (TA) and acetabular depth-width ratio (ADR). Acetabular dysplasia was considered for LCEA < 20 degrees or TA > 10 degrees . Femoral parameters consisted of the most recent head diameter, neck-shaft angle, neck length, articulotrochanteric distance and alpha angle. Results: At SCFE onset, the affected hip showed a slightly lower LCEA (26.4 degrees sd 6.1 degrees versus 27.3 degrees sd 5.7 degrees ; p = 0.01) and ADR (330 sd 30 versus 340 sd 30; p < 0.001) compared with the uninvolved hip. At final follow-up, the affected hip showed lower LCEA (24.5 degrees sd 7.6 degrees versus 28.8 degrees sd 6.6 degrees ; p < 0.001) and ADR (330 sd 40 versus 350 sd 40; p < 0.001), and TA was larger (5.5 degrees sd 5.4 degrees versus 2.3 degrees sd 4.2 degrees ; p < 0.001) compared with the uninvolved hip. Acetabular dysplasia was observed in 27 (25%) of 108 hips with SCFE. Femoral head overgrowth, age at slip and SCFE severity were independent factors associated with acetabular dysplasia (p < 0.05). Conclusion: Acetabular coverage and depth are not increased in SCFE, and the acetabular coverage tends to decrease up to skeletal maturity. A potential disturbance in the acetabular growth and remodelling exists mainly for young children with severe SCFE, and a potential for acetabular insufficiency may be observed at the diagnosis and follow-up of SCFE. Level of Evidence: Prognostic Level IV. PMID- 30294369 TI - MRI in idiopathic, stable, slipped capital femoral epiphysis: evaluation of contralateral pre-slip. AB - Purpose: Early diagnosis and treatment of slipped capital femoral epiphysis (SCFE) is important to prevent slip progression and avoid complications. We sought to determine if MRI findings in patients with unilateral SCFE could indicate 'pre-slip' or predict future SCFE in the contralateral hip. Methods: A prospective study evaluated patients with unilateral SCFE over a two-year period. MRI of the asymptomatic hip was performed within the perioperative period. Patients were followed with radiographs until a contralateral slip occurred or until physeal closure. Demographics, clinical stability, severity, posterior slope angle (PSA), modified Oxford Bone Score (mOBS) and patency of the triradiate cartilage were recorded and statistical analysis performed. Results: In all, 33 of 54 patients with unilateral SCFE were enrolled into the study. In all, 29 (87.8%) had complete follow-up. Five of the enrolled patients (15.2%) developed a sequential slip requiring in situ pinning. Six of 33 (18.2%) patients had positive MRI findings: four of which proceeded to sequential SCFE and two which did not. One sequential slip had a negative MRI. PSA predicted 1/11 sequential slips (sensitivity 9.09%, specificity 81.4%, positive predictive value (PPV) 11.1%, negative predictive value (NPV) 77.8%) and mOBS predicted 5/11 sequential slips (sensitivity 45.5%, specificity 93%, PPV 62.5%, NPV 87%). An open triradiate cartilage was present in 8/11 patients with sequential slips (sensitivity 72.7%, specificity 81.4%, PPV 50%, NPV 92.1%). Conclusion: MRI findings consistent with 'pre-slip' were present in 66.7% of patients who developed a sequential SCFE. Further study on the utility/sensitivity of MRI in predicting sequential SCFE is warranted. Level of Evidence: II, diagnostic. PMID- 30294370 TI - San Diego pelvic osteotomy in patients with closed triradiate cartilage. AB - Purpose: A San Diego pelvic osteotomy is frequently used as part of the surgical treatment of neuromuscular patients with hip displacement. This short-term follow up study assesses the effectiveness of this osteotomy in patients with closed triradiate cartilage compared with open triradiates. Methods: Retrospective review of 43 patients (44 hips) with neuromuscular hip disease who underwent a San Diego pelvic osteotomy to correct hip displacement. In all 24 hips had open triradiate cartilage at the time of surgery and 20 hips were closed. Centre edge angle (CEA), acetabular angle (AA) and Reimer's index (RI) were recorded from preoperative, postoperative and the latest follow-up radiographs and statistical analysis was performed. Results: CEA improved by 39 degrees (7 degrees to 69 degrees ) in the open group and 30 degrees (9 degrees to 80 degrees ) in the closed group from preoperative radiographs to postoperative, with no significant difference in improvement between groups (p = 0.084). There was no significant difference in AA between the open (improved by 11 degrees (3 degrees to 23 degrees )) and closed (improved by 10 degrees (4 degrees to 21 degrees )) groups (p = 0.65). RI improved from 61% to 11% in the open group and 51% to 12% in the closed group. There was no statistically significant difference between groups in RI at preoperative, immediate postoperative and final follow-up radiographs. At latest follow-up, CEA, AA and RI all remained relatively stable in both groups. Conclusions: San Diego pelvic osteotomy is equally effective in improving radiographic parameters in neuromuscular patients with both open and closed triradiate cartilage. This study challenges the notion that closed triradiate cartilage is a contraindication to a San Diego pelvic osteotomy. Level of Evidence: III. PMID- 30294371 TI - MRI and sonography in Legg-Calve-Perthes disease: clinical relevance of containment and influence on treatment. AB - Purpose: The containment orientated treatment of Legg-Calve-Perthes disease (LCPD) affected hip joints is broadly accepted in the literature. The prerequisite is early recognition of loss of containment. An often-used quantitative MRI containment parameter is the cartilaginous acetabulum-head-index (CAHI). Based on ultrasound (US), we analyzed the newly created 'femoral head extrusion angle' (HA) as a containment parameter in comparison with the CAHI in severe LCPD. Methods: In a prospective study with 40 children (mean age 5.8 years sd 2.3) with unilateral LCPD classified as Catterall group III/IV, we measured the CAHI versus HA to assess the containment of the femoral head. HA in US was determined by the tangent from the bony acetabular rim to the cartilaginous cranio-lateral femoral head. Results: The HA was significantly higher in LCPD affected hip joints (25 degrees sd 7 degrees ) than in healthy ones (13 degrees sd 5 degrees ; p < 0.001). Correlation analysis of all hip joints revealed a significant correlation between HA and CAHI (r = -0.69; p < 0.001). Hip joints with a low CAHI indicating loss of containment showed a higher HA in sonography. Conclusion: The results of our study suggest that the HA in US is a reliable containment parameter in severe LCPD with a HA > 22 degrees defining a pathologic value. In comparison with the CAHI, HA measurement in ultrasound is easier than the assessment of various parameters to calculate an index. Frequent sonographical follow-up assessment in critical joints is an alternative if MRI is not available, helping to detect an impending loss of containment early enough. Level of Evidence: Level II. PMID- 30294372 TI - Early morbidity associated with fasciotomies for acute compartment syndrome in children. AB - Purpose: Acute compartment syndrome (ACS) requires urgent fasciotomy to decompress the relevant muscle compartment/s prior to onset of irreversible myonecrosis and nerve injury. A fasciotomy is not a benign procedure. This study aims to describe and quantify early morbidity directly associated with fasciotomies for ACS in children. Methods: Clinical charts of 104 children who underwent 112 fasciotomies over a 13-year period at a tertiary children's hospital were reviewed. The following were analyzed: ACS aetiology, fasciotomy site, number of subsequent procedures, method of wound closure, short-term complications and length of hospital stay. Results: Short-term complications included wound infections (6.7%) and the need for blood transfusion (7.7%). Median number of additional operations for wound closure was two (0 to 10) and median inpatient stay was 12 days (3 to 63; SD 11.7). After three unsuccessful attempts at primary closure, likelihood of needing skin grafting for coverage exceeded 80%. Analyses showed that fasciotomy-wound infections were associated with higher risk for four or more closure procedures. Number of procedures required for wound closure correlated with longer inpatient stay as did ACS associated with non-orthopaedic causes. Conclusion: Fasciotomy is associated with significant early morbidity, the need for multiple closure operations, and prolonged hospital stay. The decision for fasciotomy needs careful consideration to avoid unnecessary fasciotomies, without increasing the risk of permanent injury from missed or delayed diagnosis. Skin grafting should be considered after three unsuccessful closure attempts. Less invasive tests or continuous monitoring (for high-risk patients) for compartment syndrome may help reduce unnecessary fasciotomies. Level of Evidence: Level IV, Case series. PMID- 30294373 TI - Submuscular plates versus flexible nails in preadolescent diaphyseal femur fractures. AB - Purpose: To compare patient characteristics, operative time, estimated blood loss (EBL), postoperative length of hospital stay (LOS) and complications after insertion and removal of submuscular plates (SMPs) versus flexible nails (FNs) for paediatric diaphyseal femur fractures. Methods: We reviewed records of 58 children (mean age, 7.7 years SD 2.0) with diaphyseal femur fractures who underwent treatment with SMPs (n = 30) or FNs (n = 28) from 2005 to 2017 (mean follow-up, 22 months SD 28). Patients with pathological fractures or musculoskeletal comorbidities were excluded. Alpha = 0.05. Results: Insertion of FNs was associated with shorter operative time (beta = -24 mins) and less EBL (beta = -38 mL) (both, p < 0.001) compared with insertion of SMPs, after adjusting for fracture type and time from beginning of study period. Removal of FNs was also associated with shorter operative time (beta = -15 min) compared with removal of SMPs (p < 0.001). EBL during removal was similar between groups (p = 0.080). The FN group had a shorter LOS after insertion (beta = -0.2 d) compared with the SMP group (p = 0.032). Four patients treated with SMPs and three treated with FNs developed surgical site infections. Two patients treated with SMPs and seven treated with FNs experienced implant irritation that resolved with removal. No other complications occurred. Conclusion: Compared with SMPs, FNs were associated with shorter operative time (for insertion and removal), less EBL (for insertion) and shorter post-insertion LOS in patients with diaphyseal femur fractures. Level of Evidence: III. PMID- 30294374 TI - No incidence of glenohumeral joint dislocation in a review of 220 paediatric proximal humerus fractures. AB - Purpose: Proximal humerus fractures in adults are approached with a high suspicion for potential associated glenohumeral dislocation. Axillary views of the shoulder can be painful and possibly even lead to dynamic angulation of the proximal humerus fracture. The incidence of associated glenohumeral dislocation in the paediatric population is unclear and it would be useful to determine whether children with proximal humerus fracture require specific axillary view imaging to rule out dislocation. Methods: We retrospectively reviewed 220 proximal humerus fractures in 218 total children. Imaging and follow-up clinic notes were reviewed for potential glenohumeral dislocation. Results: Average patient age was 9.8 years SD 3.8 with 55% of the patients male and a wide variety of mechanisms of injury. None of the 220 fractures evaluated showed radiographic evidence of a shoulder dislocation, and all 218 children had a follow-up appointment at least 21 days after the injury without any clinical concern of a missed shoulder dislocation. Conclusion: No paediatric patients presenting with proximal humerus fractures had a corresponding glenohumeral joint dislocation in our relatively large series. We recommend obtaining this additional imaging only in cases with higher energy mechanisms, if there is suspicion of subluxation or dislocation on anteroposterior and scapular-Y views or if there is clinical concern.

AB - Purpose: Open reduction and internal fixation with a tension band construct is the standard treatment for displaced transverse intra-articular olecranon fractures. The purpose of this study is to describe the outcomes of tension band fixation of olecranon fractures in children, specifically assessing the need for revision fixation and hardware removal. Methods: Patients less than 18 years of age diagnosed with a displaced transverse intra-articular olecranon fracture and treated with tension band fixation between 2008 and 2017 were retrospectively enrolled. Operative treatment was with tension band wire (TBW) or tension band suture (TBS) constructs. Results: A total of 46 patients, 36 male and ten female with a mean age of 12.3 years (6 to 17), were included. Surgical fixation was with TBW in 17 patients and TBS in 29 patients. Revision fixation due to failure and fracture displacement was required in 6% of the TBW group and 14% of the TBS group (p = 0.19). The patients who required revision fixation in the TBS group were older (14.7 years versus 11.6 years, p = 0.05) and heavier (70.5 kg versus 48.5 kg, p = 0.05) than those in the same group who did not require revision fixation. Conclusion: Paediatric olecranon fractures treated with TBW or TBS fixation unite in the majority of patients with similar need for hardware removal due to prominence and/or pain between fixation techniques. In a select group of older patients weighing greater than 50 kg, TBS constructs demonstrate increased failure rates, requiring revision fixation, and should be avoided in this population group. Level of Evidence: IV. PMID- 30294376 TI - Is less more? Assessing the utility of early clinical and radiographic follow-up for operative supracondylar humerus fractures. AB - Purpose: Postoperative protocols following surgical management of supracondylar humerus fractures (SCFs) are often based upon surgeon preference rather than clinical merit. The purpose of this study is to determine the utility of early clinical and radiographic follow-up. Methods: A retrospective review of patients who underwent closed reduction and percutaneous pinning (CRPP) for SCF between 2009 and 2015 was performed using a database of prospectively-collected consecutive patient data. Previously undiagnosed neuropathies documented at the first postoperative visit were identified. Unscheduled visits and postoperative complications were compared between patients who were seen at one week and those with delayed first clinic visits. Results: Of 873 patients, 823 (94.3%) were seen within ten days of surgery (early follow-up) and 50 (5.7%) had a delayed first clinic appointment. Among patients seen for early follow-up, 12 (1.5%) had a previously undocumented neuropathy diagnosed but only eight (1%) had an alteration of management secondary to clinical findings. Greater than 90% of patients seen for early follow-up had radiographs performed, but only one had an alteration in management due to radiographic findings. Patients seen for early follow-up had the same rate of unscheduled visits (2.9% versus 4%, p = 0.66) and postoperative complications (1.6% versus 0%, p > 0.99) as those with delayed first appointments. Radiographic parameters were comparable at final follow-up (Baumann's angle 74.5 degrees versus 73.7 degrees , p = 0.40; lateral humeral condylar angle 40.2 degrees versus 41.2 degrees , p = 0.53). Conclusion: The early follow-up visit after CRPP of SCF rarely leads to alterations in care and does not reduce unscheduled visits or late complications. Level of Evidence: Level IV. PMID- 30294377 TI - A comparison of screw versus drill and curettage epiphysiodesis to correct leg length discrepancy. AB - Purpose: To compare two common surgical techniques of epiphysiodesis: drill/curettage epiphysiodesis (PDED) versus cross screw epiphysiodesis (PETS). The hypothesis is that the two techniques have similar efficacy but demonstrate differences in length of hospital stay (LOS), time to return to activity and complication rates. Methods: A retrospective review of growing children and adolescents less than 18 years old who required an epiphysiodesis with leg-length discrepancy (LLD) of 2 cm to 6 cm with minimum two years of follow-up was conducted. Characteristics including age at surgery, gender, epiphysiodesis location, side, operative time, LOS and hardware removal were compared across treatment groups. LLD, expected growth remaining (EGR) and bone age were determined preoperatively and at most-recent visit. The correction ratio (change in EGR) was calculated along with a 95% confidence interval (CI) to assess if correction in leg length was achieved. Results: A total of 115 patients underwent epiphysiodesis in the femur (53%), tibia (24%) or a combination (24%). The cohort was 47% male, with a mean age of 12.6 years (7.7 to 17.7) at surgery. Median follow-up was 3.7 years (2.0 to 12.7). In all, 23 patients underwent PETS and 92 patients had PDED. Both treatment groups achieved expected LLD correction. There was no significant difference in median operative time, complication rates or LOS. PETS patients returned to activity at a mean 1.4 months (interquartile range (IQR) 0.7 to 2.1) while PDED patients returned at a mean 2.4 months (IQR 1.7 to 3) (p < 0.001). Conclusion: Effectiveness in achieving expected correction, LOS and operative time are similar between screw and drill/curettage epiphysiodesis. Patients undergoing PETS demonstrated a faster return to baseline activity than patients with PDED. Level of Evidence: III. PMID- 30294378 TI - A new technique for correction of leg length discrepancies in combination with complex axis deformities of the lower limb using a lengthening nail and a locking plate. AB - Purpose: Intramedullary lengthening nails are an accepted alternative to external fixators but are limited by anatomical preconditions. Therefore, to date the use of external fixators is sometimes inevitable. We report on a new technique for correction of combined limb length discrepancies and complex axis deformities using solely internal devices - a lengthening nail and a locking plate. Methods: Between October 2008 and November 2011 five patients (two femora, three tibias) with a mean leg length discrepancy of 36 mm (25 to 50) and a complex angular deformity were treated with a fully implantable motorized lengthening nail (Fitbone) and a locking plate. All patients were evaluated with regards to the pre- and postoperative leg length as well as axis alignment, functional outcome, lengthening indices and complications. Results: A successful leg length equalization was achieved in all cases and physiological joint orientation angles in all but one case. The mean distraction index was 1.2 mm/day, the maturation index 24 days/cm and the consolidation index 35 days/cm. The functional outcome was very encouraging in all cases with bilateral free range of movement. In total, two complications were observed, one nonunion and one loss of leg length after an early locking bolt removal in a peripheral hospital. Conclusion: The combination of a fully implantable motorized lengthening nail and a locking plate is a valuable alternative option for treating selected cases with limb length discrepancies in combination with a complex deformity of the lower leg. However, the reported technique puts high demands on the preoperative planning, operative technique as well as surgeon's skills. Level of evidence: IV (retrospective series). PMID- 30294379 TI - Range of motion in the talo-navicular and the calcaneo-cuboid joints evaluated by ultrasound during clubfoot treatment with normal references up to the age of four years. AB - Purpose: Previous ultrasound studies of clubfeet have mainly focused on the first year of life. The purpose of this study was to improve the evaluation of the talo navicular and calcaneo-cuboid joints by adding new variables, evaluating the repeatability of ultrasound measurements for normal feet and clubfeet and establishing values for normal feet up to four years of age. Methods: A control group of 105 children divided into ten age groups, and 71 clubfeet in 46 children were examined. Four new variables were introduced: medial malleolus-Talar head Navicular distance, medial tangent of the talus to the medial border of the navicular distance, the angle between the longitudinal axis of the talus and a line from the centre of the talar head to the medial corner of the navicular, the angle between the lateral borders of the calcaneus and the cuboid. The mobility in the talo-navicular and the calcaneo-cuboid joints was assessed by comparing measurements with the foot in adduction and abduction. Results: The variables could be assessed with fair to very good intra- and inter-observer repeatability (intraclass correlation coefficient > 0.8 and >= 0.6, respectively), with a few exceptions. There was less movement in talo-navicular and calcaneo-cuboid joints in clubfeet than in controls. Conclusion: Morphology of normal feet and clubfeet, as well as mobility in the talo-navicular and calcaneo-cuboid joints, can be assessed by ultrasound with a fair to very good reliability from birth to the age of four years.

AB - Purpose: There have been no prospective studies investigating gastrointestinal (GI) symptoms of patients with adolescent idiopathic scoliosis (AIS) following posterior spinal fusion (PSF). The purpose of this study was to evaluate the incidence and severity of self-reported GI symptoms following PSF. Methods: In all, 40 AIS patients undergoing PSF were prospectively enrolled between March 2015 and October 2016. Patients completed a survey on each postoperative, inpatient day regarding nausea, emesis, constipation, abdominal pain and back pain, rating their pain on a scale of 1 to 10. Results: Abdominal pain (50%), emesis (63%), nausea (65%) and constipation (68%) were experienced by the majority of patients. Of those reporting back pain, the mean pain level during the postoperative period was 5.1 (0.2 to 9.6). Of those reporting abdominal pain, the mean pain level during the postoperative period was 5.5 (1.4 to 8.6), which was not different than the severity of their back-pain levels (mean = 6.0, p = 0.31). Conclusions: Gastrointestinal issues in AIS patients following PSF are common. Abdominal pain was as severe as the back pain for half of the patients. Level of Evidence: II. PMID- 30294381 TI - What influences contracture formation in lower motor neuron disorders, severity of denervation or residual muscle function? An analysis of the elbow contracture in 100 children with unilateral Brachial Plexus Birth Injury. AB - Purpose: As in other neuromuscular disorders, both denervation and muscle paresis/imbalance are implicated as aetiological factors for contractures in children with a Brachial Plexus Birth Injury (BPBI). Although both factors are related, it is unclear which factor is dominant. The aim of this study is to assess whether contracture formation in children is predominantly related to denervation or to residual muscle function/imbalance. This might be relevant for understanding contracture formation in other neuromuscular disorders. Methods: A total of 100 children (61 boys; mean age 10.4 years, 4 to 18) with unilateral BPBI were included in this cross-sectional study. Severity of the denervation was classified according to Narakas. Muscle function of flexors and extensors of both elbows was measured (in Newtons) using a hand-held dynamometer and flexion contractures were measured with a goniometer. The relation between denervation, muscle function/muscle balance and flexion contracture was assessed using univariate and multivariate analysis. Results: Of the children, 57 were Narakas class I, 13 class II and 30 class III. Mean flexion contracture was 25 degrees (90 degrees to -5 degrees ). At the affected side the forearm flexion force was 47% and extension force was 67% of the force of the unaffected side. Contractures were more severe in children with higher Narakas classifications (p = 0.001), after neurosurgery (Mann-Whitney U test, p = 0.009) and were related to age (Spearman's Rho = -0.3, p = 0.008) and to paresis of the extensors (Rho = 0.4, p = 0.000). Flexor paresis as a percentage of unaffected side (Rho = 0.06, p = 0.6) and muscle balance had no influence. Conclusion: In BPBI, elbow contractures are related to the severity of the neurological lesion, not to residual muscle function. Level of evidence: Level II - prognostic study. PMID- 30294382 TI - Intraoperative 2D C-arm and 3D O-arm in children: a comparative phantom study. AB - Purpose: Exposure to ionizing radiation is a concern for children during intraoperative imaging. We aimed to assess the radiation exposure to the paediatric patient with 2D and 3D imaging. Methods: To evaluate the radiation exposure, patient absorbed doses to the organs were measured in an anthropomorphic phantom representing a five-year-old child, using thermoluminescent dosimeters. For comparative purposes, organ doses were measured using a C-arm for one minute of fluoroscopy and one acquisition with an O-arm. The cone-beam was centred on the pelvis. Direct and scattered irradiations were measured and compared (Student's t-test). Skin entrance dose rates were also evaluated. Results: All radiation doses were expressed in uGy. Direct radiation doses of pelvic organs were between 631.22 and 1691.87 for the O-arm and between 214.08 and 737.51 for the C-arm, and were not significant (p = 0.07). Close scattered radiation on abdominal organs were between 25.11 and 114.85 for the O arm and between 8.03 and 55.34 for the C-arm, and were not significant (p = 0.07). Far scattered radiation doses on thorax, neck and head varied from 0.86 to 6.42 for the O-arm and from 0.04 to 3.08 for the C-arm, and were significant (p = 0.02). The dose rate at the skin entrance was 328.58 uGy.s-1 for the O-arm and 1.90 with the C-arm. Conclusion: During imaging of the pelvis, absorbed doses for a 3D O-arm acquisition were higher than with one minute fluoroscopy with the C arm. Further clinical studies comparing effective doses are needed to assess ionizing risks of the intraoperative imaging systems in children. PMID- 30294383 TI - Population and forest dynamics during the Central European Eneolithic (4500-2000 BC). AB - The population boom-and-bust during the European Neolithic (7000-2000 BC) has been the subject of lively discussion for the past decade. Most of the research on this topic was carried out with help of summed radiocarbon probability distributions. We aim to reconstruct population dynamics within the catchment of a medium sized lake on the basis of information on the presence of all known past human activities. We calculated a human activity model based on Monte Carlo simulations. The model showed the lowest level of human activity between 4000 and 3000 BC. For a better understanding of long-term socio-environmental dynamics, we also used the results of a pollen-based quantitative vegetation model, as well as a local macrophysical climate model. The beginning of the decline of archaeologically visible human activities corresponds with climatic changes and an increase in secondary forest taxa probably indicating more extensive land-use. In addition, important social and technological innovations, such as the introduction of the ard, wheel, animal traction and metallurgy, as well as changes in social hierarchy characterizing the same period. PMID- 30294384 TI - Efficient two-stage designs and proper inference for animal studies. AB - Cost-effective yet efficient designs are critical to the success of animal studies. We propose a two-stage design for cost-effectiveness animal studies with continuous outcomes. Given the data from the two-stage design, we derive the exact distribution of the test statistic under null hypothesis to appropriately adjust for the design's adaptiveness. We further generalize the design and inferential procedure to the K-sample case with multiple comparison adjustment. We conduct simulation studies to evaluate the small sample behavior of the proposed design and test procedure. The results indicate that the proposed test procedure controls the type I error rate for the one-sample design and the family wise error rate for K-sample design very well; whereas the naive approach that ignores the design's adaptiveness due to the interim look severely inflates the type I error rate or family-wise error rate. Compared with the standard one-stage design, the proposed design generally requires a smaller sample size. PMID- 30294385 TI - Mindfulness-Based Interventions for Young Offenders: a Scoping Review. AB - Youth offending is a problem worldwide. Young people in the criminal justice system have frequently experienced adverse childhood circumstances, mental health problems, difficulties regulating emotions and poor quality of life. Mindfulness based interventions can help people manage problems resulting from these experiences, but their usefulness for youth offending populations is not clear. This review evaluated existing evidence for mindfulness-based interventions among such populations. To be included, each study used an intervention with at least one of the three core components of mindfulness-based stress reduction (breath awareness, body awareness, mindful movement) that was delivered to young people in prison or community rehabilitation programs. No restrictions were placed on methods used. Thirteen studies were included: three randomized controlled trials, one controlled trial, three pre-post study designs, three mixed-methods approaches and three qualitative studies. Pooled numbers (n = 842) comprised 99% males aged between 14 and 23. Interventions varied so it was not possible to identify an optimal approach in terms of content, dose or intensity. Studies found some improvement in various measures of mental health, self-regulation, problematic behaviour, substance use, quality of life and criminal propensity. In those studies measuring mindfulness, changes did not reach statistical significance. Qualitative studies reported participants feeling less stressed, better able to concentrate, manage emotions and behaviour, improved social skills and that the interventions were acceptable. Generally low study quality limits the generalizability of these findings. Greater clarity on intervention components and robust mixed-methods evaluation would improve clarity of reporting and better guide future youth offending prevention programs. PMID- 30294386 TI - Intervention Integrity in Mindfulness-Based Research. AB - Assessing program or intervention fidelity/integrity is an important methodological consideration in clinical and educational research. These critical variables influence the degree to which outcomes can be attributed to the program and the success of the transition from research to practice and back again. Research in the Mindfulness-Based Program (MBP) field has been expanding rapidly over the last 20 years, but little attention has been given to how to assess intervention integrity within research and practice settings. The proliferation of different program forms, inconsistency in adhering to published curriculum guides, and variability of training levels and competency of trial teachers all pose grave risks to the sustainable development of the science of MBPs going forward. Three tools for assessing intervention integrity in the MBP field have been developed and researched to assess adherence and/or teaching competence: the Mindfulness-Based Cognitive Therapy-Adherence Scale (MBCT-AS), the Mindfulness Based Relapse Prevention-Adherence and Competence Scale (MBRP-AC), and the Mindfulness-Based Interventions: Teaching Assessment Criteria (MBI:TAC). Further research is needed on these tools to better define their inter-rater reliability and their ability to measure elements of teaching competence that are important for participant outcomes. Research going forward needs to include systematic and consistent methods for demonstrating and verifying that the MBP was delivered as intended, both to ensure the rigor of individual studies and to enable different studies of the same MBP to be fairly and validly compared with each other. The critical variable of the teaching also needs direct investigation in future research. We recommend the use of the "Template for Intervention Description and Replication" (TIDieR) guidelines for addressing and reporting on intervention integrity during the various phases of the conduct of research and provide specific suggestions about how to implement these guidelines when reporting studies of mindfulness-based programs. PMID- 30294387 TI - Towards an Objective Measure of Mindfulness: Replicating and Extending the Features of the Breath-Counting Task. AB - Despite calls for objective measures of mindfulness to be adopted in the field, such practices have not yet become established. Recently, a breath-counting task (BCT) was proposed as a reliable and valid candidate for such an instrument. In this study, we show that the psychometric properties of the BCT are reproducible in a sample of 127 Asian undergraduates. Specifically, accuracy on the BCT was associated with everyday lapses and sustained attention, and weakly associated with subjectively measured mindfulness. BCT metrics also showed good test-retest reliability. Extending the use of the paradigm, we further found that two different types of task errors-miscounts and resets-were correlated with different aspects of cognition. Miscounts, or errors made without awareness, were associated with attentional lapses, whereas resets, or self-caught errors, were associated with mind-wandering. The BCT may be a suitable candidate for the standardized measurement of mindfulness that could be used in addition to mindfulness questionnaires. PMID- 30294388 TI - A Close Examination of the Relationship Between Self-Compassion and Depressive Symptoms. AB - Self-compassion has shown to be beneficial for individuals' wellbeing; in particular, it has been associated with lower levels of depressive symptoms. The purpose of this study was to further explore the association between self compassion, as measured by the Self-Compassion Scale (SCS), and depressive symptoms, in a large representative sample of community adults (n = 734, Mean age = 55.7, SD = 15.2). We examined the association of depressive symptoms with the SCS total score, the SCS six subscales (i.e., self-kindness, common humanity, mindfulness, self-judgment, isolation, and over-identification), and the SCS positive and negative items (referred to as self-compassion and self-coldness, respectively). In addition, we explored the predictive ability of self compassion, self-coldness, and the SCS six subscales on depressive symptoms both cross-sectionally and over a 1-year period of time. Finally, we sought to test the moderating role of self-compassion on the association between self-coldness and depressive symptoms. Results showed that the SCS negative items and subscales were more strongly related to depressive symptoms than the SCS positive items and subscales. Accordingly, self-coldness was a stronger predictor of depressive symptoms, cross-sectionally and over a 1-year timeframe, when compared with self compassion. Particularly, the feeling of being isolated was shown to be strongly associated with depressive symptoms. We did not find substantial evidence for a moderating role of self-compassion on the association between self-coldness and depressive symptoms. Future research needs to determine the added value of assessing self-coldness and whether or not it is an essential part of self compassion. PMID- 30294389 TI - On the Association Between Mindfulness and Romantic Relationship Satisfaction: the Role of Partner Acceptance. AB - In three studies, it was investigated whether trait mindfulness is positively associated with partner acceptance, defined as the ability and willingness to accept the partner's imperfections, and whether partner acceptance explains the association between trait mindfulness and relationship satisfaction. Trait mindfulness, partner acceptance and relationship satisfaction were assessed in two MTurk samples (n 1 = 190; n 2 = 140) and a sample of participants of a mindfulness-based stress reduction course (n 3 = 118) and their partners (53 complete couples), using self-report measures. In all three samples, trait mindfulness was related to partner acceptance and in two out of three studies trait mindfulness was directly positively related to relationship satisfaction. Also, the results provided initial support for the mediating role of partner acceptance in the association between mindfulness and relationship satisfaction. Dyadic data further suggested that the benefits of mindfulness and partner acceptance on relationship satisfaction extend from the individual to the partner through increased partner acceptance. Together, the results provide initial support for the hypothesis that partner acceptance may be an important mechanism through which mindfulness promotes relationship satisfaction in both partners of a romantic couple. PMID- 30294390 TI - Improvements in Stress, Affect, and Irritability Following Brief Use of a Mindfulness-based Smartphone App: A Randomized Controlled Trial. AB - Mindfulness training, which involves observing thoughts and feelings without judgment or reaction, has been shown to improve aspects of psychosocial well being when delivered via in-person training programs such as mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT). Less is known about the efficacy of digital training mediums, such as smartphone apps, which are rapidly rising in popularity. In this study, novice meditators were randomly allocated to an introductory mindfulness meditation program or to a psychoeducational audiobook control featuring an introduction to the concepts of mindfulness and meditation. The interventions were delivered via the same mindfulness app, were matched across a range of criteria, and were presented to participants as well-being programs. Affect, irritability, and two distinct components of stress were measured immediately before and after each intervention in a cohort of healthy adults. While both interventions were effective at reducing stress associated with personal vulnerability, only the mindfulness intervention had a significant positive impact on irritability, affect, and stress resulting from external pressure (between group Cohen's d = 0.44, 0.47, 0.45, respectively). These results suggest that brief mindfulness training has a beneficial impact on several aspects of psychosocial well-being, and that smartphone apps are an effective delivery medium for mindfulness training. PMID- 30294392 TI - Accessing the elite figured world of science. AB - This review explores Jackson and Seiler's "I am smart enough to study post secondary science: A critical discourse analysis of latecomers' identity construction in an online forum" by considering the analytic framework for figured worlds guiding this study. We consider the specific affordances of cultural production theory for examining how sociohistorical and cultural discourses of science as elite impact individuals at every level of education. We then extend this discussion by exploring how an informal learning space at a prestigious science museum was designed to explicitly tackle cultural discourses of science as elite that act as barriers to identification with science. PMID- 30294391 TI - High-Risk Acute Promyelocytic Leukemia with Unusual T/Myeloid Immunophenotype Successfully Treated with ATRA and Arsenic Trioxide-Based Regimen. AB - We describe two patients with acute promyelocytic leukemia (APL) with an unusual immunophenotype with co-expression of myeloperoxidase (MPO) with cytoplasmic CD3 (cCD3) representing myeloid and T-lineage differentiation. Both harbored FLT3-ITD mutations. One additionally had a deletion in the PML gene affecting the primer binding site, thus limiting measurable residual disease (MRD) analysis during follow-up. Both patients achieved durable remission with all-trans retinoic acid (ATRA) and arsenic trioxide (ATO)-based therapy, thus mitigating the need for repetitive conventional chemotherapy cycles and allogeneic stem cell transplantation. Our report highlights the complexity and challenge of diagnosis and management of APL due to the variant immunophenotype and genetics, and underscores the importance of synthesizing information from all testing modalities. The association of the unusual immunophenotype and FLT3-ITD mutation illustrates the plasticity of the hematopoietic stem cell and the pathobiology of leukemia with mixed lineage or lineage infidelity. PMID- 30294393 TI - Outcomes of Wavefront-Optimized Laser-Assisted In-Situ Keratomileusis and Photorefractive Keratectomy for correction of Myopia and Myopic Astigmatism over One Year Follow-Up. AB - Background: Laser corneal refractive surgery suits, technology and nomograms are improving with time. This may improve the refractive and visual outcomes of the patients. Objectives: To evaluate the safety, efficacy, stability, and predictability of wavefront-optimized photorefractive keratectomy and Laser assisted in-situ keratomileusis in patients with myopia and myopic astigmatism over 1-year using WaveLight(r) EX500 Excimer Laser machine. Methods: In this prospective cohort study, refractive and visual outcomes in 596 eyes (365 patients), either having myopia or myopic astigmatism were assessed. Patients were divided into Two groups: 1) Patients who underwent PRK (53 eyes have myopia and 217 eyes have myopic astigmatism), 2) Patients who underwent LASIK (53 eyes have myopia and 273 eyes have myopic astigmatism). Results: At 12 months postoperatively 94.3% of the myopic patients reached their preoperative best corrected distance visual acuity at the final one year follow up visit post PRK and LASIK. In patients with myopic astigmatism who underwent LASIK and PRK, 95.2%, and 96.3% of the patients reached their preoperative best corrected distance visual acuity at the final one year follow up visit post LASIK and PRK, respectively. The efficacy and safety indices were 1.00 or more for all groups with no eye lost any line of best corrected distance visual acuity. Conclusion: Our study results confirm the excellent efficacy, safety, good predictability and stability of myopia / myopic astigmatism correction by either wavefront- optimized LASIK or PRK over 1-year follow-up without significant differences between them using the WaveLight(r) EX500 excimer laser system. PMID- 30294394 TI - Effectiveness of the "Create Sensitivity" Caring Model on Blood Glucose/ Glycosylated Hemoglobin and Quality of Life in Patients With Type 2 Diabetes. AB - Objective: This study aimed to determine the effectiveness of the "Create Sensitivity" caring model on blood glucose/ glycosylated hemoglobin and quality of life in patients with type 2 Diabetes. Methods: This study enrolled 70 patients from an educational hospital in Kurdistan, Iran. The model was implemented among the test group over a period of 3 months. Blood glucose/ glycosylated hemoglobin and patients' quality of life were measured before and after intervention. Data were analyzed using version 21 of the statistical software SPSS. Results: After the intervention, significant differences existed between the test and control groups both in blood glucose levels (means, 146.4 +/ 51.3 mg/dl and 175.6 +/- 59.8 mg/dl, respectively; P=0.032) and in glycosylated hemoglobin (means, 67.89 +/- 13.34 mmol/mol and 80.03 +/- 17.234 mmol/mol, respectively; P= 0.002). Additionally, there was also a significant difference between the quality of life of the patients in test group (mean, 58.25 +/- 5.3) and that in the control group (mean, 47.02 +/- 4.5) (P= 0.0001). Conclusion: Use of this model was associated with reducing fasting blood glucose and glycosylated hemoglobin and increasing the total mean of quality of life in the patients in the test group. So, the application of this model is recommended. PMID- 30294395 TI - Structural and electronic properties of CdTe1-xSex films and their application in solar cells. AB - The performance improvement of conventional CdTe solar cells is mainly limited by doping concentration and minority carrier life time. Alloying CdTe with an isovalent element changes its properties, for example its band gap and behaviour of dopants, which has a significant impact on its performance as a solar cell absorber. In this work, the structural, optical, and electronic properties of CdTe1-xSex films are examined for different Se concentrations. The band gap of this compound changes with composition with a minimum of 1.40 eV for x = 0.3. We show that with increasing x, the lattice constant of CdTe1-xSex decreases, which can influence the solubility of dopants. We find that alloying CdTe with Se changes the effect of Cu doping on the p-type conductivity in CdTe1-xSex, reducing the achievable charge carrier concentration with increasing x. Using a front surface CdTe1-xSex layer, compositional, structural and electronic grading is introduced to solar cells. The efficiency is increased, mostly due to an increase in the short-circuit current density caused by a combination of lower band gap and a better interface between the absorber and window layer, despite a loss in the open-circuit voltage caused by the lower band gap and reduced charge carrier concentration. PMID- 30294396 TI - Risk factors for hospital readmission among Swedish older adults. AB - Introduction: Hospital readmissions of older persons are common and often associated with complex health problems. The objectives were to analyze risk factors for readmission within 30 days from hospital discharge. Methods: A prospective study with a multifactorial approach based on the population-based longitudinal Swedish Adoption/Twin Study of Aging (SATSA) was conducted. During 9 years of follow-up, information on hospitalizations, readmissions and associated diagnoses were obtained from national registers. Logistic regression models controlling for age and sex were conducted to analyze risk factors for readmissions. Results: Of the 772 participants, [mean age 69.7 (+/- 11.1), 84 (63%)] were hospitalized and among these 208 (43%) had one or several readmissions within 30 days during the follow-up period. Most of the readmissions (57%) occurred within the first week; mean days from hospital discharge to readmission was 7.9 (+/- 6.2). The most common causes of admission and readmission were cardiovascular diseases and tumors. Only 8% of the readmissions were regarded as avoidable admissions. In a multivariate logistic regression, falling within the last 12 months (OR 0.57, p = 0.039) and being a male (OR 1.84, p = 0.006) increased the risk of readmission. Conclusions: Most older persons that are readmitted return to hospital within the first week after discharge. Experiencing a fall was a particular risk factor of readmission. Preventive actions should preferably take place already at the hospital to reduce the numbers of readmission. Still, it should be remembered that most readmissions were considered to be necessary. PMID- 30294397 TI - Urinary tract infections in a geriatric sub-acute ward-health correlates and atypical presentations. AB - Purpose: Bacterial urinary tract infections (UTIs) are the most frequently occurring infectious diseases in the geriatric population. The aim of the study was to determine the prevalence and clinical features of UTIs in geriatric in patients and their association with health and functional ability characteristics. Methods: A prospective cross-sectional cohort study was conducted among patients hospitalized on the geriatric ward. Patients were interviewed, examined, and had their hospital records analyzed. An uncontaminated midstream urine sample was collected and cultured in all of the cases suspected for UTI. Relative risks for UTI were counted and multivariable logistic regression model was built. Results: 246 patients were included, 179 (72.8%) women, 210 (85.4%) 75 + -year-olds. Bacterial UTIs occurred in 18.3% of the patients. The main etiological agent was Escherichia coli (73.3%). The most significant predictors of UTI were recurrent UTI and urinary catheter. The typical clinical UTI symptoms occurred in less than half of the cases (only in 11.1% of cases fever was observed). More often, than in patients without UTIs, they reported symptoms such as delirium (28.9% vs. 18%), tachycardia (11.1% vs. 1.5%) or hypotension (20% vs. 12.1%). Conclusions: Bacterial UTIs affect about 1/5 of hospitalized geriatric patients. The clinical picture of these infections very often is atypical and it indicates a need for diagnostic vigilance. PMID- 30294398 TI - Utilization of medical rehabilitation services among older Poles: results of the PolSenior study. AB - Background: Rehabilitation tailored to older adults' needs might improve their functional performance and quality of life, as well as increase social participation. The aim of the study was to evaluate the use of medical rehabilitation services among older Poles in relation to socio-economic and health-related determinants. Materials and methods: Data regarding medical rehabilitation were obtained from the nationwide, multidisciplinary PolSenior project (2007-2012) conducted on representative sample of 4813 respondents (48.3% women) aged 65+ years. Socio-economic status, physical functioning, falls, chronic pain, and formal disability occurrence, as well as self-rated health were accounted for. Results: One in six respondents (18.9% women vs. 15.8% men, p < 0.005) underwent medical rehabilitation during 12 months prior to the survey. Respondents mostly received electrotherapy or light radiation therapy (61.3%). Multivariate logistic regression analysis revealed that women aged 80+ years and men aged 90+ years had a significantly lower chance of using rehabilitation services compared to the youngest study participants (65-69 y.o.). City dwellers used rehabilitation services nearly twice as frequently as rural dwellers. Respondents with university education level were most likely to take part in these services. Dependence in IADL decreased participation in medical rehabilitation, while formal disability and chronic pain promoted utilization of rehabilitation services. Conclusions: Younger age, city dwelling, higher education, functional independence, formal disability certificate, and chronic pain increased participation in medical rehabilitation. Such results of the study should be considered in planning actions towards reducing health inequalities at the national level and promoting health and well-being among older adults. PMID- 30294399 TI - Clinical factors increasing discrepancies of renal function assessment with MDRD and Cockcroft-Gault equations in old individuals. AB - Abstract: In a daily clinical practice, glomerular filtration rate (GFR) is still estimated on the basis of short MDRD formula, whereas medications' Summaries of Product Characteristics suggest that GFR used for the dosage adjustment should be estimated based on the Cockcroft-Gault (C-G) equation. The aim of the study was to compare eGFR values calculated on the basis of short and full MDRD and C-G equations in PolSenior study participants with decreased eGFR. Methods: We have assessed differences in the estimation of GFR between short and full MDRD, as well as C-G formula, all equations utilizing non-isotope-dilution mass spectrometry-calibrated measurements of serum creatinine, in the community-based population of 760 persons aged 65 years or above (mean age 82 +/- 8 years) with estimated GFR < 60 ml/min/1.73 m2 (according to short MDRD). In addition, in our analysis, we have included the detailed characteristics of comorbidities and different aspects of mobility and functional performance. Results: The better concordance, precision, and accuracy with MDRD short formula were found for MDRDfull than C-G equation. In logistic regression analysis, female gender, activities in daily living (ADL) <= 4, and age > 80 years diminished, while visceral obesity improved accuracy (P30) of eGFR calculated according to C-G equation as compared to MDRDshort. Similar analysis did not found factors influencing P30 for MDRDfull equation. Conclusions: In very old subjects, especially females, dependent patients and those with visceral obesity, estimation of GFR based on short MDRD formula should not be used interchangeably with Cockcroft-Gault equation for the medicines dose tailoring. PMID- 30294401 TI - Chylothorax in Patients with Chronic Lymphocytic Leukemia: A Case Series. AB - Chylothorax, which is defined as the presence of chyle in the pleural space, is often caused by malignancy. However, chylothorax as a result of underlying CLL is exceedingly rare in the literature. Chyle contains fat soluble vitamins and lymphocytes, meaning that its collection into the pleural space may further exacerbate the immunosupressed state of an individual with CLL. Here, we report three cases of patients with CLL who developed chylothorax, and their management. Chylothorax, although rare with CLL, should be considered in the differential diagnosis when patients with CLL present with pleural effusions, especially if recurrent. Discovery of a chylothorax may indicate the need for further treatment of CLL. PMID- 30294402 TI - Perihepatic abscesses caused by dropped appendicoliths in a child. AB - A dropped appendicolith is a well-known complication of laparoscopic appendectomy that may occur because of stone expulsion from the appendix, before or during surgery, and typically manifests as a focal, subcentimeter area of high attenuation with or without associated abscess. Dropped appendicoliths may act as niduses for infection and may result in the future development of abscess formation. We report the case of a 10-year-old pediatric patient who developed 2 perihepatic abscesses caused by 2 appendicoliths that were inadvertently dropped during laparoscopic surgery. PMID- 30294400 TI - Antipsychotic Drug Dispensations in Older Adults, Including Continuation After a Fall-Related Hospitalization: Identifying Adherence to Screening Tool of Older Persons' Potentially Inappropriate Prescriptions Criteria Using the Nova Scotia Seniors' Pharmacare Program and Canadian Institute for Health's Discharge Databases. AB - Purpose: Despite well-established concerns regarding adverse drug effects, antipsychotics are frequently prescribed for older adults. Our first objective was to identify trends in antipsychotic dispensations to older Nova Scotians. STOPP (Screening Tool of Older Persons' Potentially Inappropriate Prescriptions) criteria identify antipsychotic use in those with a history of falls as potentially inappropriate. Our second objective was to identify trends, predictors, and adherence with this STOPP criteria by identifying continued antipsychotic dispensations following a fall-related hospitalization. Methods: A descriptive cross-sectional cohort study of Nova Scotia Seniors' Pharmacare Program (NSSPP) beneficiaries >= 66 years with at least one antipsychotic dispensation annually from April 1, 2009 to March 31, 2014 was completed. As well, unique beneficiaries with at least one antipsychotic dispensation in the four-year period between April 1, 2009 and March 31, 2013 were linked to fall related hospitalizations recorded in the Canadian Institute for Health Information Discharge Abstract Database. The relationship of age, sex, fiscal year, days supply and length-of-stay were studied to identify predictors of continued antipsychotic dispensation post-discharge. Descriptive statistics and multivariate logistic analysis were performed. Odds ratios for the association of risk factors and adherence to STOPP criteria were calculated. Findings: We identified that in each year observed, there were 6% of eligible NSSPP beneficiaries that received at least one antipsychotic dispensation. Approximately 70% of antipsychotic dispensations were for second generation agents, primarily quetiapine and risperidone. Of the unique beneficiaries with at least one antipsychotic dispensation in the four-year period between April 1, 2009 and March 31, 2013 who survived a fall-related hospitalization over 75% were dispensed an antipsychotic in the 100 days following hospital discharge. Logistic regression showed no statistically significant association between potentially inappropriate therapy and potential predictors in multivariate analysis. Implications: In each year from 2009 to 2014, 6% of Nova Scotia Seniors' Pharmacare beneficiaries were dispensed at least one antipsychotic prescription. Over 75% of the older adults who received an antipsychotic dispensation in the 100 days prior to a fall-related hospitalization, continued the drug class after discharge. This demonstrates that despite the recommendations of quality indicators such as the STOPP criteria, antipsychotics are continued in individuals at a high risk of falling. Future investigations are needed to inform health team, system, and policy interventions to improve concordance with this antipsychotic specific STOPP criterion when appropriate.

AB - In the context of recent guidelines for stroke management, application of computed tomographic perfusion (CTP) is anticipated to increase, especially within 6-24 hours after stroke onset. There are commercially available software packages to help to detect the infarct core and the penumbra, however, the results of these software are not always straightforward that might cause incorrect CTP interpretation. We present here a case of acute ischemic stroke in which the CTP software misinterpreted the results by labeling the normal hemisphere as infarction and ischemia due to luxury perfusion of the infarcted hemisphere. Awareness of laterality of the patient's symptoms and the understanding of functioning of perfusion analysis software is necessary to avoid this pitfall. PMID- 30294404 TI - COMPLEX-VALUED TIME SERIES MODELING FOR IMPROVED ACTIVATION DETECTION IN FMRI STUDIES. AB - A complex-valued data-based model with pth order autoregressive errors and general real/imaginary error covariance structure is proposed as an alternative to the commonly-used magnitude-only data-based autoregressive model for fMRI time series. Likelihood-ratio-test-based activation statistics are derived for both models and compared for experimental and simulated data. For a dataset from a right-hand finger-tapping experiment, the activation map obtained using complex valued modeling more clearly identifies the primary activation region (left functional central sulcus) than the magnitude-only model. Such improved accuracy in mapping the left functional central sulcus has important implications in neurosurgical planning for tumor and epilepsy patients. Additionally, we develop magnitude and phase detrending procedures for complex-valued time series and examine the effect of spatial smoothing. These methods improve the power of complex-valued data-based activation statistics. Our results advocate for the use of the complex-valued data and the modeling of its dependence structures as a more efficient and reliable tool in fMRI experiments over the current practice of using only magnitude-valued datasets. PMID- 30294406 TI - Double Sparsity Kernel Learning with Automatic Variable Selection and Data Extraction. AB - Learning in the Reproducing Kernel Hilbert Space (RKHS) has been widely used in many scientific disciplines. Because a RKHS can be very flexible, it is common to impose a regularization term in the optimization to prevent overfitting. Standard RKHS learning employs the squared norm penalty of the learning function. Despite its success, many challenges remain. In particular, one cannot directly use the squared norm penalty for variable selection or data extraction. Therefore, when there exists noise predictors, or the underlying function has a sparse representation in the dual space, the performance of standard RKHS learning can be suboptimal. In the literature, work has been proposed on how to perform variable selection in RKHS learning, and a data sparsity constraint was considered for data extraction. However, how to learn in a RKHS with both variable selection and data extraction simultaneously remains unclear. In this paper, we propose a unified RKHS learning method, namely, DOuble Sparsity Kernel (DOSK) learning, to overcome this challenge. An efficient algorithm is provided to solve the corresponding optimization problem. We prove that under certain conditions, our new method can asymptotically achieve variable selection consistency. Simulated and real data results demonstrate that DOSK is highly competitive among existing approaches for RKHS learning.

AB - Purpose of Review: To understand the role of antibody detection in the diagnosis of infections caused by filamentous fungi (molds). Rapid and accurate profiling of infection-causing fungal pathogens remains a significant challenge in modern health care. Classical fungal culture and serology continue to be relevant even though over the past few decades, antigen (biomarker) assays such as ELISA and lateral flow devices have been developed and validated. Recent Findings: This article reviews the current antibody detection systems (serological tests) for the diagnosis of mold infections associated with pulmonary disease and introduces new developments. Classic and more recently developed serological techniques and their performance characteristics, including immunodiffusion, complement fixation, and ELISA. Summary: The diseases covered are allergic bronchopulmonary aspergillosis, chronic pulmonary aspergillosis, invasive aspergillosis, mucormycosis, diseases caused by filamentous basidiomycetes, infection caused by Talaromyces marneffei and pythiosis. Serology remains a cornerstone for fungal diagnostic testing. PMID- 30294407 TI - The effect of shear waves in an elastic sphere on the radiation force from a quasi-Gaussian beam. AB - Ultrasound beams are capable of exerting radiation force on scattering or absorbing obstacles. Previously, our team developed a technology to reposition kidney stones using this approach. It is convenient to study the influence of different parameters using a theoretical model based on a spherical shape stone and a quasi-Gaussian acoustic beam. In such an approach, only two geometrical parameters are involved, namely the beam width and the sphere diameter. The radiation force depends on their ratio, as well as on the elastic properties of the liquid and the stone. In this work, numerical modeling was performed to calculate the force acting on an elastic sphere using previously developed theory. Our numerical modeling indicates that the force on a stone is strongest when the beam is slightly wider than the stone. Also, the force created by a narrow beam appears to be the strongest when the beam is targeted to the side of the sphere. These peculiarities of the radiation force are explained by more effective generation of shear waves inside the stone resulting from their effective coupling with the acoustic waves in liquid at the stone edge. PMID- 30294408 TI - Non-Uniform Microphone Arrays for Robust Speech Source Localization for Smartphone-Assisted Hearing Aid Devices. AB - Robust speech source localization (SSL) is an important component of the speech processing pipeline for hearing aid devices (HADs). SSL via time direction of arrival (TDOA) estimation has been known to improve performance of HADs in noisy environments, thereby providing better listening experience for hearing aid users. Smartphones now possess the capability to connect to the HADs through wired or wireless channel. In this paper, we present our findings about the non uniform non-linear microphone array (NUNLA) geometry for improving SSL for HADs using an L-shaped three-element microphone array available on modern smartphones. The proposed method is implemented on a frame-based TDOA estimation algorithm using a modified Dictionary-based singular value decomposition method (SVD) method for localizing single speech sources under very low signal to noise ratios (SNR). Unlike most methods developed for uniform microphone arrays, the proposed method has low spatial aliasing as well as low spatial ambiguity while providing a robust low-error with 360 degrees DOA scanning capability. We present the comparison among different types of microphone arrays, as well as compare their performance using the proposed method. PMID- 30294409 TI - New Trends in Quantitative Nuclear Cardiology Methods. AB - Purpose of review: The use of quantitative analysis in single photon emission computed tomography (SPECT) and positron emission tomography (PET) has become an integral part of current clinical practice and plays a crucial role in the detection and risk stratification of coronary artery disease. Emerging technologies, new protocols, and new quantification methods have had a significant impact on the diagnostic performance and prognostic value of nuclear cardiology imaging, while reducing the need for clinician oversight. In this review, we aim to describe recent advances in automation and quantitative analysis in nuclear cardiology. Recent Findings: Recent publications have shown that fully automatic processing is feasible, limiting human input to specific cases where aberrancies are detected by the quality control software. Furthermore, there is evidence indicating that fully quantitative analysis of myocardial perfusion imaging is feasible and can achieve at least similar diagnostic accuracy as visual interpretation by an expert clinician. In addition, the use of fully automated quantification in combination with machine learning algorithms can provide incremental diagnostic and prognostic value over the traditional method of expert visual interpretation. Summary: Emerging technologies in nuclear cardiology focus on automation and the use of artificial intelligence as part of the interpretation process. This review highlights the benefits and limitations of these applications, and outlines future directions in the field. PMID- 30294410 TI - Cancer-related cognitive impairment in breast cancer survivors: An examination of conceptual and statistical cognitive domains using principal component analysis. AB - There is a great deal of variability in the composition of neuropsychological test batteries used in the assessment of cancerrelated cognitive impairment (CRCI). Not only the development of a gold standard approach for CRCI assessment would allow for easier identification of women suffering from CRCI but it would also promote optimal care for survivors. As a first step towards the development of a valid and reliable unified test battery, the objective of this study was to verify whether the theoretical domains commonly used in CRCI assessment are statistically supported, before and after breast cancer treatment. Principal component analyses (PCA) were performed on the results from 23 neuropsychological tests grouped into eight conceptual domains. For baseline data, the Kaiser-Meyer Olkin was .82 and Bartlett's X2(253, N=95) = 949.48, P<0.001. A five-component solution explained 60.94% of the common variance. For the post-treatment data, the Kaiser-Meyer-Olkin was .83 and Bartlett's X2(253, N=95) = 1007.21, P<0.001 and a five component solution explained 62.03% of the common variance. Although a visual comparison of the theoretical model with those determined via PCA indicated important overlap between conceptual domains and statistical components, significant dissimilarities were also observed. PMID- 30294411 TI - Light-induced decarboxylation in a photo-responsive iron-containing complex based on polyoxometalate and oxalato ligands. AB - A new photoresponsive molecular polyanion in which two Fe(iii) ions are simultaneously coordinated by two [A-alpha-PW9O34]9- polyoxometalate units and two oxalato ligands has been obtained. When irradiated with UV light its potassium salt, 1, exhibits a remarkable photocoloration effect, attributable to the partial reduction of the POM units to give rise to a mixed-valence species. The photoinduced process is intramolecular and involves electron transfer from the oxalato ligands, which partially decompose releasing CO2, towards the Fe(iii) and the POM. This mechanism has been confirmed by DRS, IR, XPS and Mossbauer spectroscopy, magnetism and elemental analysis. An analogous derivative of 1 containing malonato ligands does not exhibit such photoactive behaviour, which is evidence that the oxalate ligand is essential for the photoactivity of 1. To our knowledge, 1 represents the first POM-based compound in which the photocoloration effect does not require the presence of intermolecular short interactions.

AB - Metastable states of soft matters are extensively used in designing stimuli responsive materials. However, the non-steady properties may obstruct consistent performance. Here we report an approach to eradicate the indistinguishable metastable supercooled state of functional molecular liquids (FMLs), which remains as a liquid for weeks or months before crystallizing, via rational molecular design. The phases (solid, kinetically stable liquid, and supercooled liquid) of a model FML, branched alkyl chain-substituted 9,10-diphenylanthracene (DPA), are found to be governed by subtle alterations of the molecular structure (alkyl-DPA ratio and bulkiness of the DPA unit). We thus outline molecular design principles to avoid supercooled FML formation. Moreover, we demonstrate a practical technique to rapidly discriminate supercooled FMLs (within 5 h) by accelerating their crystallization in differential scanning calorimetry heating via pre-annealing or relatively slow scanning. PMID- 30294418 TI - Facile room temperature synthesis of large graphene sheets from simple molecules. AB - The largest graphene sample obtained through a chemical reaction under ambient conditions (temperature and pressure), using simple molecules such as benzene or n-hexane as precursors, is reported. Starting from a heterogeneous reaction between solid iron chloride and the molecular precursor (benzene and n-hexane) at a water/oil interface, graphene sheets with micrometric lateral size are obtained as a film deposited at the liquid/liquid (L/L) interface. The pathway involving the cyclization and aromatization of n-hexane to benzene at the L/L interface, and the sequence of conversion of benzene to biphenyl and biphenyl to condensed rings (which originates the graphene structures) was followed by different characterization techniques and a mechanistic proposal is presented. Finally, we demonstrate that this route can be extended for the synthesis of N-doped graphene, using pyridine as the molecular precursor. PMID- 30294419 TI - Direct evidence for heme-assisted solid-state electronic conduction in multi-heme c-type cytochromes. AB - Multi-heme cytochrome c (Cytc) proteins are key for transferring electrons out of cells, to enable intracellular oxidation to proceed in the absence of O2. In these proteins most of the hemes are arranged in a linear array suggesting a facile path for electronic conduction. To test this, we studied solvent-free electron transport across two multi-heme Cytc-type proteins: MtrF (deca-heme Cytc) and STC (tetra-heme Cytc). Transport is measured across monolayers of these proteins in a solid state configuration between Au electrodes. Both proteins showed 1000* higher conductance than single heme, or heme-free proteins, but similar conductance to monolayers of conjugated organics. Conductance is found to be temperature-independent (320-80 K), suggesting tunneling as the transport mechanism. This mechanism is consistent with I-V curves modelling, results of which could be interpreted by having protein-electrode coupling as rate limiting, rather than transport within the proteins. PMID- 30294420 TI - Genome mining, isolation, chemical synthesis and biological evaluation of a novel lanthipeptide, tikitericin, from the extremophilic microorganism Thermogemmatispora strain T81. AB - Genome mining of the New Zealand extremophilic microorganism Thermogemmatispora strain T81 indicated the presence of biosynthetic machinery to produce several different peptidic natural products. Solid-phase culture of T81 led to the isolation of tikitericin 1, a new lanthipeptide characterised by four (methyl)lanthionine bridges. The mass-guided isolation and structural elucidation of tikitericin 1 is described together with its total synthesis via Fmoc-solid phase peptide synthesis (SPPS). The key non-canonical (methyl)lanthionine residues were synthesised in solution phase via an improved synthetic route and subsequently assembled to construct the peptide backbone using Fmoc-SPPS. N Terminal truncated analogues of tikitericin (2-5) were also prepared in order to evaluate the contribution of each sequential ring of the polycyclic lanthipeptide to the antibacterial activity. PMID- 30294421 TI - Copper catalyzed photoredox synthesis of alpha-keto esters, quinoxaline, and naphthoquinone: controlled oxidation of terminal alkynes to glyoxals. AB - Herein, we report a facile visible light induced copper catalyzed controlled oxidation of terminal C[triple bond, length as m-dash]C alkynes to alpha-keto esters and quinoxalines via formation of phenylglyoxals as stable intermediates, under mild conditions by using molecular O2 as a sustainable oxidant. The current copper catalysed photoredox method is simple, highly functional group compatible with a broad range of electron rich and electron poor aromatic alkynes as well as aliphatic alcohols (1 degrees , 2 degrees and 3 degrees alcohols), providing an efficient route for the preparation of alpha-keto esters (43 examples), quinoxaline and naphthoquinone with higher yields than those in the literature reported thermal processes. Furthermore, the synthetic utility of the products has been demonstrated in the synthesis of two biologically active molecules, an E. coli DHPS inhibitor and CFTR activator, using the current photoredox process. In addition, we applied this methodology to the one-pot synthesis of a heterocyclic compound (quinoxaline, an FLT3 inhibitor) by trapping the intermediate phenylglyoxal with O-phenylenediamine. The intermediate phenylglyoxal can also be isolated and further reacted with an internal alkyne to form naphthoquinone. This process can be readily scaled up to the gram scale. PMID- 30294422 TI - Hyaluronic acid hydrogel scaffolds loaded with cationic niosomes for efficient non-viral gene delivery. AB - The lack of ideal non-viral gene carriers has motivated the combination of delivery systems and tissue-engineered scaffolds, which may offer relevant advantages such as enhanced stability and reduced toxicity. In this work, we evaluated a new combination between niosome non-viral vectors and hyaluronic acid (HA) hydrogel scaffolds, both widely studied due to their biocompatibility as well as their ability to incorporate a wide variety of molecules. We evaluated three different niosome formulations (niosomes 1, 2 and 3) varying in composition of cationic lipid, helper lipid and non-ionic tensioactives. Niosomes and nioplexes obtained upon the addition of plasmid DNA were characterized in terms of size, polydispersity, zeta potential and ability to transfect mouse bone marrow cloned mesenchymal stem cells (mMSCs) in 2D culture. Niosome 1 was selected for encapsulation in HA hydrogels due to its higher transfection efficiency and the formulation was concentrated in order to be able to incorporate higher amounts of DNA within HA hydrogels. Nioplex-loaded HA hydrogels were characterized in terms of biomechanical properties, particle distribution, nioplex release kinetics and ability to transfect encapsulated mMSCs in 3D culture. Our results showed that nioplex-loaded HA hydrogel scaffolds presented little or no particle aggregation, allowed for extensive cell spreading and were able to efficiently transfect encapsulated mMSCs with high cellular viability. We believe that the knowledge gained through this in vitro model can be utilized to design novel and effective platforms for in vivo local and non viral gene delivery applications. PMID- 30294423 TI - Generation of controllable gaseous H2S concentrations using microfluidics. AB - Hydrogen sulfide (H2S) plays an important role as an intercellular and intracellular signaling molecule, yet its targets are not well understood. As a molecule it easily evaporates and it is hard to acquire stable concentration for in vitro studies, constituting a major problem for the field to identify its downstream targets and function. Here we develop a microfluidic system that can provide consistent and controllable H2S levels in contrast to the current method of delivering large bolus doses to cells. The system relies on the permeability of H2S gas through a polydimethylsiloxane thin membrane. A hydrogen sulfide donor, sodium hydrosulfide, is perfused in the microchannels below the gas permeable membrane and gaseous H2S diffuses across the membrane, providing a stable concentration for up to 5 hours. Using electrochemical sensors within 3 ppm range, we found that H2S concentration was dependent on two parameters, the concentration of H2S donor, sodium hydrosulfide and the flow rate of the solution in the microchannels. Additionally, different H2S concentration profiles can be obtained by alternating the flow rate, providing an easy means to control the H2S concentration. Our approach constitutes a unique method for H2S delivery for in vitro and ex vivo studies and is ideally suited to identify novel biological processes and cellular mechanisms regulated by H2S.

PMID- 30294426 TI - Is patellofemoral pain a precursor to osteoarthritis?: Patellofemoral osteoarthritis and patellofemoral pain patients share aberrant patellar shape compared with healthy controls. AB - Objectives: It has been hypothesized that patellofemoral pain, a common knee condition in adolescents and young adults, may be a precursor of degenerative joint changes and may ultimately lead to patellofemoral osteoarthritis. Since both conditions share several mechanical disease characteristics, such as altered contact area between the femur and patella and increased joint stress, we investigated whether these conditions share similar and different shape characteristics of the patella compared with normal controls. Methods: This cross sectional study compared three different study populations: 32 patellofemoral pain subjects (mean age, 32 years (22 to 45); 72% female); 56 isolated radiological patellofemoral osteoarthritis subjects (mean age, 54 years (44 to 58); 89% female); and 80 healthy control subjects (mean age, 52 years (44 to 58); 74% female). Measurements included questionnaires, and lateral and skyline radiographs of the knee. Two separate 30-point 2D statistical shape models of the patella were created from the lateral and skyline radiographs. A general linear model was used to test for differences in standardized shape modes (a specific shape variant of the patella) between patellofemoral osteoarthritis, patellofemoral pain, and controls, using Bonferroni correction and adjustment for body mass index and gender. Results: Five shape modes showed statistically significant differences between groups: skyline modes 1 (p < 0.001), 8 (p = 0.004), and 10 (p < 0.001); and lateral modes 5 (p = 0.002) and 7 (p = 0.002). Skyline mode 8 and lateral mode 5 were similar for patellofemoral osteoarthritis and patellofemoral pain populations, while being statistically significant different from the control group. Conclusion: Our results indicate that patellofemoral pain and patellofemoral osteoarthritis share similar shape characteristics, which are different from control subjects. These findings support the proposed continuum disease model of patellofemoral pain predisposing to the development of patellofemoral osteoarthritis.Cite this article: J. F. A. Eijkenboom, J. H.

AB - Purpose: A colorectal anastomotic leakage (CAL) is a major complication after colorectal surgery and leads to high rates of morbidity and prolonged hospital stay. The study aims to evaluate the benefit of using bilirubin, urobilinogen, pancreas elastase and bile acid in the drain fluid (DF) as a predictive marker for the CAL. Methods: From June 2015 to October 2017 100 patients, who underwent left hemicolectomy (LH), sigma resection (SR), high anterior resection (HAR), low anterior resection (LAR) or reversal of Hartmann's Procedure (ROHP) were included in this monocentric non-randomized prospective clinical trial. During the first four postoperative days (POD) the concentration of bilirubin, urobilinogen, pancreas elastase and bile acid in the DF was measured. Results: In total 100 patients were recruited. 17 were excluded due to intraoperative decisions to conduct a protective stoma. 6 patients had a CAL. The patients of the control group (n = 77) and the patients who suffered from a CAL (n = 6) had no increased concentration of urobilinogen and pancreas elastase in the DF. The concentration of bile acid in the DF of the patients who suffered from a CAL differed from those of the control group on the 4th POD (p = 0.055).The concentration of bilirubin in the DF of the patients who suffered from a CAL significantly differed from those of the control group on the 1st POD (p = 0.031) and on the 3rd POD (p = 0.041). Conclusion: Bilirubin and bile acid in the DF may function as a predictive marker for a CAL.

AB - Background: Secondary hyperparathyroidism(sHPT) is one of the most serious complications in long-term hemodialysis patients. Patients may suffer from metabolic bone diseases, severe atherosclerosis and undesirable cardiovascular events. Endoscopic parathyroidectomy with autotransplantation is a treatment option for those who do not respond to clinical management. Methods: 6 patients with secondary hyperparathyroidism were treated with endoscopic parathyroidectomy and autotransplantation. Pieces of parathyroid tissue were squeezed in our novel self-made device and injected into brachioradialis. Results: Preoperative symptoms were alleviated, and the serum PTH and alkaline phosphatase levels, hyperphosphatemia, and hypercalcemia were improved or normalized in all 6 patients. The preparation time of parathyroid fragments for autotransplantation was less than 10 min in all 6 patients.Pathological examinations revealed parathyroid cells remains active. Conclusion: Application of the novel squeezing device is an economic, effective and safe way in endoscopic parathyroidectomy and autotransplantation for patients with secondary hyperparathyroidism. PMID- 30294429 TI - A single epitope of Epstein-Barr Virus stimulate IgG production in mice. AB - Background: Epstein-Barr virus (EBV) is closely associated with the high incidence of nasopharyngeal carcinoma in worldwide. Vaccination is one strategy with the potential to prevent the occurrence of EBV-associated cancers, but a suitable vaccine is yet to be licensed. Much vaccine development research focuses on the GP350/220 protein of EBV as it contains an immunogenic epitope at residues 147-165, which efficiently stimulates IgG production in vitro. We examined the ability of this epitope (EBVepitope) to induce IgG production in mice. Methods: The antibody binding pattern of the epitope was analyzed using bioinformatics tools. The IgG production in mice were examined by FACS CaliburTM Flow cytometer. Results: The epitope bound the 72A1 monoclonal antibody at the same site as GP350/220 protein, indicating that the epitope should stimulate B cells to produce antibody. Moreover, in vivo administration of EBVepitope successfully induced IgG expression from B cells, compared with controls. Further investigation indicated that the relative number of B cells expressing IgE in EBVepitope-treated mice was lower than controls. Conclusions: Our data suggest that this EBV GP350 epitope is able to induce IgG expression in vivo without causing allergic reactions, and represents a potential EBV vaccine candidate. PMID- 30294430 TI - A new clinical-ultrasound score to predict difficult videolaparocholecystectomies: A prospective study. AB - Background: The gold standard treatment of symptomatic cholelithiasis is videolaparoscopic cholecystectomy (VLC). The aim of this study is to produce a predictive clinical ultrasound (US) score for difficult VLC to reduce the rate of conversion to open cholecystectomy surgery and intra and/or post-operative complications. Methods: In this prospective study carried out in 2017 we enrolled 135 patients (pts) who underwent VLC in our General Surgery Unit. A specific pre operative abdominal ultrasound scan was performed to assess gallbladder characteristics for each patient. All US and patients' characteristics were recorded in a standard form in order to obtain a preoperative score and were then added to the intra-operative variables. Results: The analysis revealed a statistical significance between post-operative characteristics and parietal thickness, adhesions, stratifications and volume of gallstones. Comparing the degree of difficulty VLC assessed in the pre-operative stage to the intraoperative score, the sensitivity of the preoperative US scan test is 91.8% while the specificity is 76.7%. Conclusions: The variables which proved statistically significant in predicting a difficult cholecystectomy were: age, parietal thickness >3 mm, adhesions, stratifications, gallstones >2 cm and fixed gallstones. We have definitively defined a predictive score for difficult VLC for which a VLC is to be considered potentially difficult whenever it presents a pre operative score equal or greater than 4 (and a "easy" one with a pre-operative score less than 4). These findings may prove helpful in further reducing the conversion rate and the rate of intra- and/or post-operative complications. PMID- 30294431 TI - Case report: Laparoscopic approach in the treatment of presacral lipoma. AB - Retrorectal lipoma, as well as other retrorectal tumours, is a relatively rare disorder. Retrorectal tumours accounted for 1 in 40,000 hospital admissions. We present a case of retrorectal lipoma, 15 cm * 10 cm * 8 cm in size, treated by the laparoscopic approach. The preoperative magnetic resonance imaging visualised a mass, 12 cm * 6.7 cm * 8.6 cm in diameter, in the retrorectal space, spreading toward the left obturator foramen. Surgery was indicated due to exclude malignant process certainly, because it is difficult to differentiate lipoma from low-grade liposarcoma on non invasive imaging. Laparoscopic extirpation of the tumour was performed. The overall operative time was 80 min. The diagnosis of lipoma was established on histological examination. The patient was discharged from hospital on the 2nd day after the surgery. We have found this minimally invasive operation to be an effective and well-tolerated treatment option, determined by the experience of the surgeon. PMID- 30294432 TI - Patient's views of the consent process for groin hernia repair: Use of consent template improves compliance with best practice (Original research). AB - Background: Informed consent obtained for day case surgery has been historically incomplete. An assessment of consenting practice for groin hernia was performed relative to existing gold standards and patient's perception of the consent process was evaluated with a questionnaire. The aim of the study was to identify areas of improvement to comply with best practice. Methods: A retrospective audit of adult patients undergoing groin hernia repair (June-November 2016) at a tertiary care centre was performed. The same cohort of patients was surveyed with a self-administered questionnaire to identify their view on consenting practice. Results: 113 patients were identified who underwent groin hernia repair during the study period. Pre-printed consent templates-stickers (as opposed to hand written) were used in 53(47%) cases. In 75(66%) cases, there was complete documentation of the risks and benefits of surgery. 81(72%) patients received information about the full benefits of surgery. 27(23%) patients received partial information and 7(6%) patients had no mention of benefit recorded. Postoperative recovery was fully explained to 85(75%) patients. Use of pre-printed templates ensured 100% documentation compared to handwritten consent forms (risks 37%, benefits 47%, and recovery 53%). Preference for the timing of consent was in clinic (64%), day of surgery (25%). 34(56%) felt the choice for the technique and 22(36%) felt the choice for anaesthesia. Satisfaction was non-significantly better in those consented in clinic (87% versus 76% p = 0.74). 49(80%) felt happy with the overall consent process. 57(93%) felt that they received support and advice. 60(98%) responders felt confidence in the National Health Service and 59(97%) would recommend treatment to family and friends. Conclusions: The use of pre-printed consent and discharge summary templates improve compliance with best practice. Whilst patient preference favours consent in the outpatient clinic, satisfaction levels were high wherever consent was obtained. Patients should have more choice. PMID- 30294433 TI - Does pisiform subluxation affect the postoperative outcomes in a cohort of patients with distal radius fractures? AB - Background: In this study, we retrospectively surveyed the presence or absence of pisiform subluxation in surgically treated distal radius fractures (DRF) cases. In addition, we investigated whether or not the postoperative short-term treatment outcome differs due to the presence of pisiform subluxation. Materials and methods: The subjects were 134 DRF patients treated with volar locking plate fixation (53 males and 81 females, mean age: 64 years old). The pisotriquetral joint was observed on a preoperative CT to investigate the presence or absence of pisiform subluxation according to the criteria reported by Vasilas. 134 patients divided into subluxation group and non-subluxation group, and the clinical outcomes were compared between these groups. Results: Pisiform subluxation was noted in 23.1% (31 patients, 15 males and 16 females, mean age 61 years). No significant difference was noted in patient background in both groups. The postoperative pronation angle in the non-subluxation group was significantly greater than that in the subluxation group, but there was no significant difference in any other parameter (the range of motion of the wrist, grip strengths, VAS, Q-DASH scores, and Mayo score) between these 2 groups. However it concomitantly occurred in 23.1% of DRF cases in our series, there was no significant difference in the postoperative treatment outcome between these 2 groups. Conclusions: Therapeutic intervention of pisiform subluxation is unnecessary during treatment of DRF, since pisiform subluxation does not affect the postoperative clinical outcomes of distal radius fractures. PMID- 30294434 TI - Experimental comparative study of thrombogenicity of two differently luminal heparinized ePTFE vascular prosthetics. AB - Introduction: ; Heparin bonded grafts have proven to improve patency, at least transiently.Two different heparin bonded expanded polytetrafluoroethylene (ePTFE) grafts produced by different technologies are currently available.This pilot primary goal was to test these commonly used, but differently heparinized ePTFE grafts for differences in primary patency after a 6-months follow-up in a sheep model. Secondly, the aim was to establish a large animal model to enable future translational studies and further graft development. Method: ; End-to-side bypass of the common carotid artery was performed bilaterally in sheep. Either a Gore(r) Propaten heparinized graft or a Jotec(r) Flowline Bipore heparinized graft was used, both 5 mm in diameter.Following graft implantation, the sheep were kept on pasture for 6 months, with monthly duplex scans to determine patency. At termination, the grafts were duplex scanned a final time, with the animals sedated, and the grafts were removed for heparin activity analysis. Results: ; 14 sheep were operated, 11 survived total follow-up time. At final follow-up, 4 patent Gore(r) grafts, and 6 Jotec(r) remained. Mean patency time was 106.7 +/- 21.9(SD) days and 96.2 +/- 25.9(SD) days for Gore(r) and Jotec(r), respectively. Log-rank test showed no significant difference at final follow-up after 6 months. Post mortem heparin analysis showed no significant difference in mean activity. Conclusion: ; Based on patency data alone, no significant difference between these grafts were found. In accordance, heparin activity analysis showed no difference between the grafts. The model itself, proved easily implementable, and provides many possibilities for future studies, though some adjustments should be made to improve survival. PMID- 30294435 TI - Complete resection of an anterior mediastinal tumor by total arch replacement and pulmonary artery trunk plasty with a pericardial patch: A case report. AB - Introduction: Patients with undiagnosed anterior mediastinal tumors commonly undergo surgery for diagnosis and treatment. However, determining the optimal therapeutic strategy is difficult for tumors with substantial invasion, such as lesions touching the aortic arch (AA). Case presentation: A 76-year-old man of Asian descent presented to our hospital because chest computed tomography (CT) revealed an anterior mediastinal tumor. This tumor surrounded the left subclavian vein and touched the AA. We suspected the tumor to be malignant. We therefore decided to resect the tumor with preparation for total arch replacement (TAR). The operation was performed in three steps. First, we performed a mediastinal sternotomy. However, the tumor had invaded the subclavian vein, so we resected this vein after adding a transmanubrial approach. However, because of invading the AA we needed next step. Second, we shifted the patient to the right lateral decubitus position. We performed partial resection of the left upper lobe and exfoliated the distal AA. Third, we shifted the patient to the dorsal position and implanted an artificial cardiopulmonary device, after which we performed TAR, and pulmonary artery (PA) trunk plasty with a pericardial patch. The operation was successful, with no major adverse events. Pathologically, the tumor was diagnosed as diffuse large B-cell lymphoma. Discussion: If oncologically complete resection is preferable for tumors with substantial invasion, complete resection should be attempted even if the surgery is difficult. Conclusion: We performed complete resection of an anterior mediastinal tumor with TAR and PA trunk plasty using a pericardial patch. PMID- 30294436 TI - Absence of cognitive symptoms in a 6-year-old male with post-traumatic increased intracranial pressure - A case report. AB - Introduction: Traumatic Brain Injuries (TBIs) can range from mild to severe, and may result in increased intracranial pressure (ICP). Increased ICP causes hallmark physical signs, such as diaphoresis, emesis, fixed pupils, and altered mental status. Monitoring the patient's score on the Glasgow Coma Scale (GCS) and cranial CT scans are routine measures used in clinical practice to monitor the development of a TBI. Presentation of the case: A 6-year-old male fell off his father's shoulders and subsequently presented to ED for suspected head trauma. He was transferred to our Level 1 Trauma Center after a head CT scan demonstrated a subdural hematoma. His GCS score remained 15. The next day he began to have episodes of apnea and desaturation. Further imaging indicated expansion of the hematoma with a 5mm midline shift. He remained consistently alert and a neurological exam revealed cranial nerves to be grossly intact. Increased ICP was reduced with several days of hypertonic saline treatment without surgical intervention. Discussion: TBIs can have long-lasting effects in pediatric patients and are typically assessed using both diagnostic imaging and clinical judgment. CT scans are used to assess for hematoma development, while loss of consciousness (LOC) and altered mental status are standard clinical diagnostic indicators of increased ICP. This patient remained alert with a GCS score of 15, although he had clinical signs of increased ICP including apnea and bradycardia with a midline shift confirmed on imaging. Conclusion: While GCS is an important prognostic indicator in TBI, patients should still be monitored to assure resolution of all symptoms. PMID- 30294437 TI - Neuromuscular electrical stimulation is ineffective for treating quadriceps muscle wasting with ruptured aneurysm: A case report. AB - Introduction: Neuromuscular electrical stimulation (NMES) is a preventive intervention for muscle wasting in patients with aneurysms during the acute phase; however, its efficacy still remains unclear. In this case study, we report the effects of NMES on quadriceps muscle wasting for a patient with ruptured middle cerebral artery aneurysms during the acute phase. Presentation of case: A 66-year-old woman was admitted because of a ruptured middle cerebral artery aneurysm resulting from intracerebral hematoma with subarachnoid hemorrhage. The following day, the patient started undergoing 60-120-min NMES treatment for both her quadriceps muscles, which was continued for 10 days in 2 weeks. Quadriceps muscle thickness as measured by ultrasonography was decreased in both sides (26% and 35% for the right and left sides, respectively). The compound muscle action potential (CMAP) amplitude in the peroneal nerve was also decreased in both sides (73% vs 76%). Discussion: The lack of efficacy of NMES in preventing muscle wasting is the decreased CMAP amplitude in this patient, which showed the possibility of existence of critical illness polyneuropathy. Conclusion: NMES had no effect on quadriceps muscle wasting in a patient with ruptured middle cerebral artery aneurysms who had decreased CMAP amplitude in the peroneal nerve during the acute phase. NMES is not effective for patients with peripheral nerve conduction abnormalities. PMID- 30294438 TI - Preliminary radiological result after establishment of hospital-based trauma registry in level-1 trauma hospital in developing country setting, prospective cohort study. AB - Introduction: Injuries are the second most common cause of disability, the fifth most common cause of healthy years of life lost per 1000 people and unfortunately 90% of mortality takes place in low-to middle-income countries. Trauma registries guide policymakers and health care providers in decision making in terms of resource allocation as well as enhancing trauma care outcomes. Furthermore data from these registries inform policy makers to decrease the rate of death and disability occurring as a result of injuries. We present our experience in setting up an orthopedic trauma registry and the first short term follow-up of radiological outcomes. Materials and methodology: Our study is a non-funded, non commercial, prospective cohort study that was registered at Research Registry. The primary objectives of our study included assessing pattern of injuries in patients with upper and lower limb skeletal trauma presenting to our tertiary care academic university hospital and their respective outcomes. Data was collected by the musculoskeletal service line team members supervised by an experienced research associate and trauma consultants. The work has been reported in line with the STROCSS criteria. Results: A total of 177 patients were included in this analysis, of whom 101 (57.1%) patients had lower limb fractures, 64(36.1%) patients ad upper limb fractures and 12 (6.8%) patients had both upper and lower limbs involved. A total of 189 upper and lower limb fracture cases were recorded. 176 patients (93.1%) underwent surgeries and 13(6.9%) were managed nonoperatively. Roentgenographic outcomes were assessed using radiological criteria for each bone fractured. Conclusion: Establishing a trauma registry assists in identification of the pattern of injuries presenting to the hospital which helps in priority setting, care management and planning. This continuous audit of outcomes in turn, plays a significant role in quality improvement. PMID- 30294439 TI - Small bowel obstruction from migrated intragastric balloon. AB - Intestinal obstruction resulted from balloon migration is an extremely rare but serious late complication of the intragastric balloon (IGB). The aim of this study is to report a case of small bowel obstruction occurring in a middle age corpulent female following embedding of IGB. A 47-year-old obese female presented with abdominal pain, nausea, and vomiting for two days. She had a history of an endoscopically placed IGB nine months before presentation. Physical examination showed an obese woman with mild distress, and the right upper abdomen was tender. The plain abdominal radiograph showed gas shadow in the stomach and the duodenum, esophago-gastro-duodenoscopy showed an empty stomach and balloon migration from the stomach. Under general anesthesia, laparotomy was performed, a three centimeter antimesenteric enterotomy was done and the balloon extracted from the proximal jejunum. Intestinal obstruction is an extremely rare complication of IGB. It should be managed by laparotomy and extraction of the balloon. PMID- 30294440 TI - Rare case of symmetrical peripheral gangrene due to septic shock, disseminated intravascular coagulation and inotropic use. AB - Introduction: Symmetrical peripheral gangrene (SPG) is a rare syndrome defined by the peripheral ischemic lesion of two or more extremities in the absence of major vascular obstructive disease. Presentation of case: A 45yo woman, admitted in intensive care unit due to urinary septic shock, in need of high doses of amines, developed cold extremities with acrocyanosis that rapidly progressed to gangrene. Laboratory analysis revealed increased inflammatory parameters, liver shock, thrombocytopenia, prolonged coagulation times, increased D-Dimers and isolation of Acinetobacter baumanni in urine culture. An intravenous vasodilator was initiated with clinical benefits. After improvement and delimitation of the lesions, the patient underwent the amputation of the distal phalanges of the 2nd, 3rd and 4th fingers of the right hand and the toes of both feet. Discussion/conclusion: Even though there is no consensus regarding SPG treatment, consequences should be mitigated, particularly when vasodilators are used, in order to avoid major amputation. PMID- 30294441 TI - How to approach Monteggia-like lesions in adults: A review. AB - Monteggia-like lesions encompass a wide spectrum of fractures of the forearm and elbow associated with dislocations, subluxations and ligamentous lesions. Many attempts have been made to classify these injuries, not only to understand their pathology but also to develop optimal treatments. Unfortunately, although some of these classifications are complete, they are either complex, not immediately usable, or not exhaustive. An orthopedic surgeon who aims to rapidly treat this kind of injury needs a visual classification, and knowledge of the best surgical approach. Monteggia like lesions do not allow for mistakes during surgery, as even a minor error could be prove detrimental to performing and completing all surgical steps. In this paper, based on our extensive experience in treating these rare lesions, we suggest a practical guide to the best surgical approach for various types of Monteggia like lesions. Some technical tips and pitfalls are also described. PMID- 30294442 TI - Gallbladder cancer in Eastern Province of Saudi Arabia: A retrospective cohort study. AB - Background: There is paucity in the literature regarding gallbladder cancer in Saudi Arabia, possibly because it is not among the top 10 cancers diagnosed nationwide according to the Saudi Cancer Registry. Moreover, national or regional data on gallbladder cancer in Saudi Arabia have not been analyzed. The purpose of this study was to describe the presentation, disease stage, histology, and survival rates for gallbladder cancer in Saudi patients at a single institution between January 1, 2010 and December 31, 2017. Materials and methods: This was a retrospective study of 76 patients who presented to our hospital between January 1, 2010 and December 31, 2017, with established diagnosis of gallbladder carcinoma. The diagnosis was made either histopathologically following simple laparoscopic cholecystectomy or biopsy from metastatic liver lesion in patients with gallbladder mass, or the high suspicion of gallbladder carcinoma based on incidental radiological findings. Presentation, disease stage, histology, and treatment modalities were analyzed using descriptive statistics and frequency distributions. Survival rates were analyzed and presented using Kaplan-Meier curves. Results: Based on initial analyses the disease was more frequent among women (62.0%) than men (39.0%). Surgical resection was attempted in 40.8% patients. The average age at presentation and diagnosis of gallbladder carcinoma was 62.4 years. The disease had two peaks, one at 51.0 years and the other between 66.0 and 70.0 years. The median survival time for the overall at-risk patients was only 1.0 year, while for stage IVB patients was 7.2 months. Adenocarcinoma not otherwise specified (NOS) was the most common histopathology type (75.0%), with most patients presenting with stage IVB disease (75.0%). Gallbladder carcinoma was incidentally detected in 42.1%, including three cases (3.9%) diagnosed at our hospital. Conclusions: Gallbladder cancer is a rare type of cancer in Saudi Arabia, and most patients are treated surgically, despite being mostly diagnosed at the advanced stage of the disease. PMID- 30294443 TI - Postoperative complications following tonsil and adenoid removal in Kuwaiti children: A retrospective study. AB - Background: Adenoidectomy and adenotonsillectomy are two of the most common procedures that are performed by otolaryngologists around the world. Complications, ranging from major to minor ones, are affected by the preoperative symptoms and health status of the patient. We aimed to identify the prevalence of major postadenoidectomy and adenotonsillectomy complications, including bleeding, and minor complications, including malodor, fever, and snoring. Materials and methods: We conducted a retrospective chart review of 825 patients who underwent surgery between January 2002 and 30 December 2016 at our institution. Results: The bleeding complications prevalence was 4.1% (14/344) among patients with adenotonsillectomy and 1.3% (6/480) among those who underwent adenoidectomy. Results revealed that tonsil grade 3 patients were at a reduced risk (86% reduced risk) of developing bleeding complications, compared to those with tonsil grade 2 [odds ratio (OR) = 0.141, 95% confidence interval (CI): (0.028, 0.715)]. Grade C tympanogram patients had ten times the odds of bleeding complications compared to those with tympanogram grade A [OR = 10.6, 95% CI: 0.917, 122.54], a marginally significant difference (probability value (PV) = 0.054). Upper respiratory tract infections (URTIs) patients had three times the odds of bleeding complications compared to those without URTIs [OR = 3.03, 95% CI: (0.979, 9.439)], also a marginally significant difference (PV = 0.055). Postoperatively, 71% experienced no malodor, 23% had malodor lasting 3-7 days, and 1% had malodor for 7-10 days. Our analysis showed that 71% of the patients did not complain of snoring, 25% had snoring for 3-7 days, and 2% had snoring for 7-10 days. 80% of the patients did not develop fever, 13% had fever for 3-7 days, and no patients experienced fever for longer than 7 days. Conclusions: Nearly 4% of the patients developed bleeding after adenotonsillectomy and only 2% of the patients had only bleeding after adenoidectomy. Conversely, 15-25% of the patients developed minor complications, including malodor, snoring, and fever, independent of their preoperative symptoms. PMID- 30294444 TI - The role of stable isotopes in understanding rainfall interception processes: A review. AB - The isotopic composition of water transmitted by the canopy as throughfall or stemflow reflects a suite of processes modifying rainfall. Factors that affect isotopic composition of canopy water include fractionation, exchange between liquid and vapor, and selective transmittance of temporally varying rainfall along varying canopy flowpaths. Despite frequent attribution of canopy effects on isotopic composition of throughfall to evaporative fractionation, data suggest exchange and selection are more likely the dominant factors. Temporal variability in canopy effects is generally consistent with either exchange or selection, but spatial variability is generally more consistent with selection. However, most investigations to date have not collected data sufficient to unambiguously identify controlling processes. Using isotopic data for improved understanding of physical processes and water routing in the canopy requires recognizing how these factors and processes lead to patterns of isotopic variability, and then applying this understanding towards focused data collection and analysis. PMID- 30294445 TI - The in vivo fates of plant viral nanoparticles camouflaged using self-proteins: overcoming immune recognition. AB - Nanoparticles offer a promising avenue for targeted delivery of therapies. To slow clearance, nanoparticles are frequently stealth-coated to prevent opsonization and immune recognition. Serum albumin (SA) has been used as a bio inspired stealth coating. To develop this shielding strategy for clinical applications, it is critical to understand the interactions between the immune system and SA-camouflaged nanoparticles. This work investigates the in vivo processing of SA-coated nanoparticles using tobacco mosaic virus (TMV) as a model system. In comparing four different SA-formulations, the particles with high SA coverage conjugated to TMV via a short linker performed the best at preventing antibody recognition. Irrelevant of the coating chemistry, all formulations led to similar levels of TMV-specific antibodies after repeat administration in mice; importantly though, SA-specific antibodies were not detected and the TMV-specific antibodies were unable to recognize shielded SA-coated TMV. Upon uptake in macrophages, the shielding agent and nanoparticle separate, where TMV trafficked to the lysosome and SA appears to recycle. The distinct intracellular fates of the TMV carrier and SA shielding agent explain why anti-TMV but not SA-specific antibodies are generated. This work characterizes the outcomes of SA-camouflaged TMV after immune recognition, and highlights the effectiveness of SA as a nanoparticle shielding agent. PMID- 30294446 TI - Controlling excimer formation in indolo[3,2,1-jk]carbazole/9H-carbazole based host materials for RGB PhOLEDs. AB - Three novel materials (5CzICz, Cz2ICz and Cz3ICz), based on the indolo[3,2,1 jk]carbazole and 9H-carbazole building blocks, with high triplet energies (E T > 2.80 eV) and good thermal stability (T g > 101 degrees C) were synthesized, characterized and applied as host materials in PhOLED devices. In course of the preparation of the materials, an improved protocol for the synthesis of the indolo[3,2,1-jk]carbazole moiety has been developed. The careful molecular design of the title compounds allowed to avoid excimer formation of the indolo[3,2,1 jk]carbazole subunits in thin films. Therefore, the improved molecular design broadened the applicability of indolo[3,2,1-jk]carbazole host materials and significantly enhanced the efficiency of PhOLED devices based on these derivatives compared to previously reported indolo[3,2,1-jk]carbazole based compounds. Accordingly, employing the newly developed materials red (CEmax: 32.7 cd A-1, PEmax: 31.0 lm W-1, EQEmax: 20.4%), green (CEmax: 81.0 cd A-1, PEmax: 87.4 lm W-1, EQEmax: 21.5%) and blue (CEmax: 35.5 cd A-1, PEmax: 39.9 lm W-1, EQEmax: 18.0%) PhOLED devices with a remarkably low efficiency roll-off at 1000 cd m-2 (Cz2ICz - red: 5%; green: 0%; blue: 6%) were fabricated.

AB - An asymmetric synthesis of the C1 to C11 and C14 to C18 fragments of the macrocyclic portion of the antibiotic Leucascandrolide A was achieved in 21 total steps from an achiral dienoate. The key 4-hydroxy-2,5-pyran portion of the natural product was established by oxy-Michael cyclization of a 5,7,9,11-tetraol intermediate, which in turn was established by an iterative asymmetric-hydration of dienoates. Alternative strategies for establishing the polyol stereochemistry were explored. PMID- 30294448 TI - Metacognitive therapy versus cognitive-behavioural therapy in adults with generalised anxiety disorder. AB - Background: Cognitive-behavioural therapy (CBT) is the treatment of choice for generalised anxiety disorder (GAD), yielding significant improvements in approximately 50% of patients. There is significant room for improvement in the outcomes of treatment, especially in recovery. Aims: We aimed to compare metacognitive therapy (MCT) with the gold standard treatment, CBT, in patients with GAD (clinicaltrials.gov identifier: NCT00426426). Method: A total of 246 patients with long-term GAD were assessed and 81 were randomised into three conditions: CBT (n = 28), MCT (n = 32) and a wait-list control (n = 21). Assessments were made at pre-treatment, post-treatment and at 2 year follow-up. Results: Both CBT and MCT were effective treatments, but MCT was more effective (mean difference 9.762, 95% CI 2.679-16.845, P = 0.004) and led to significantly higher recovery rates (65% v. 38%). These differences were maintained at 2 year follow-up. Conclusions: MCT seems to produce recovery rates that exceed those of CBT. These results demonstrate that the effects of treatment cannot be attributed to non-specific therapy factors. Declaration of interest: A.W. wrote the treatment protocol in MCT and several books on CBT and MCT, and receives royalties from these. T.D.B. wrote the protocol in CBT and has published several articles and chapters on CBT and receives royalties from these. All other authors declare no competing interests. PMID- 30294449 TI - Deaths in custody in the Irish prison service: 5-year retrospective study of drug toxicology and unnatural deaths. AB - : Mental health and substance misuse disorders are associated with unnatural deaths in prisoners. Deaths in Irish prisons between 2009 and 2014 were retrospectively analysed using coroner's findings, including post-mortem toxicology. There were 69 deaths in custody, 38 of which met inclusion criteria. All deaths by overdose (16) were positive for illicit drugs; 53% of deaths (8 of 15) due to hanging were also positive for illicit drugs, and 29% of deaths (2 of 7) from other causes were toxicology positive. In conclusion, 26 unnatural deaths (68%) were associated with use of illicit drugs, which are a major contributory factor to deaths of prisoners. Declaration of interest: None. PMID- 30294450 TI - Development and clinimetric assessment of a nurse-administered screening tool for movement disorders in psychosis. AB - Background: Movement disorders associated with exposure to antipsychotic drugs are common and stigmatising but underdiagnosed. Aims: To develop and evaluate a new clinical procedure, the ScanMove instrument, for the screening of antipsychotic-associated movement disorders for use by mental health nurses. Method: Item selection and content validity assessment for the ScanMove instrument were conducted by a panel of neurologists, psychiatrists and a mental health nurse, who operationalised a 31-item screening procedure. Interrater reliability was measured on ratings for 30 patients with psychosis from ten mental health nurses evaluating video recordings of the procedure. Criterion and concurrent validity were tested comparing the ScanMove instrument-based rating of 13 mental health nurses for 635 community patients from mental health services with diagnostic judgement of a movement disorder neurologist based on the ScanMove instrument and a reference procedure comprising a selection of commonly used rating scales. Results: Interreliability analysis showed no systematic difference between raters in their prediction of any antipsychotic-associated movement disorders category. On criterion validity testing, the ScanMove instrument showed good sensitivity for parkinsonism (90%) and hyperkinesia (89%), but not for akathisia (38%), whereas specificity was low for parkinsonism and hyperkinesia, and moderate for akathisia. Conclusions: The ScanMove instrument demonstrated good feasibility and interrater reliability, and acceptable sensitivity as a mental health nurse-administered screening tool for parkinsonism and hyperkinesia. Declaration of interest: None. PMID- 30294451 TI - Demographic and clinical predictors of response to internet-enabled cognitive behavioural therapy for depression and anxiety. AB - Background: Common mental health problems affect a quarter of the population. Online cognitive-behavioural therapy (CBT) is increasingly used, but the factors modulating response to this treatment modality remain unclear. Aims: This study aims to explore the demographic and clinical predictors of response to one-to-one CBT delivered via the internet. Method: Real-world clinical outcomes data were collected from 2211 NHS England patients completing a course of CBT delivered by a trained clinician via the internet. Logistic regression analyses were performed using patient and service variables to identify significant predictors of response to treatment. Results: Multiple patient variables were significantly associated with positive response to treatment including older age, absence of long-term physical comorbidities and lower symptom severity at start of treatment. Service variables associated with positive response to treatment included shorter waiting times for initial assessment and longer treatment durations in terms of the number of sessions. Conclusions: Knowledge of which patient and service variables are associated with good clinical outcomes can be used to develop personalised treatment programmes, as part of a quality improvement cycle aiming to drive up standards in mental healthcare. This study exemplifies translational research put into practice and deployed at scale in the National Health Service, demonstrating the value of technology-enabled treatment delivery not only in facilitating access to care, but in enabling accelerated data capture for clinical research purposes.

PMID- 30294453 TI - WHEN SCIENTIFIC PARADIGMS LEAD TO TUNNEL VISION: LESSONS FROM THE STUDY OF FEAR. AB - For the past 30 years, research on the amygdala has largely focused on the genesis of defensive behaviors as its main function. This focus originated from early lesion studies and was supported by extensive anatomical, physiological, and pharmacological data. Here we argue that while much data is consistent with the fear model of amygdala function, it has never been directly tested, in part due to overreliance on the fear conditioning task. In support of the fear model, amygdala neurons appear to signal threats and/or stimuli predictive of threats. However, recent studies in a natural threat setting show that amygdala activity does not correlate with threats, but simply with the movement of the rat, independent of valence. This was true for both natural threats as well as conditioned stimuli; indeed there was no evidence of threat signaling in amygdala neurons. Similar findings are emerging for prefrontal neurons that modulate the amygdala. These recent developments lead us to propose a new conceptualization of amygdala function whereby the amygdala inhibits behavioral engagement. Moreover, we propose that the goal of understanding the amygdala will be best served by shifting away from fear conditioning toward naturalistic approach and avoidance paradigms that involve decision making and a larger repertoire of spontaneous and learned behaviors, all the while keeping an open mind. PMID- 30294454 TI - Malignant Pleural Mesothelioma presenting with Cardiac Tamponade- A Rare Case report and Review of the literature. AB - Mesothelioma is a rare tumor of the pleura, peritoneum, pericardium or tunica vaginalis. About 2,500 cases are diagnosed annually in the United States. Mesothelioma often presents with pleuritic chest pain and dyspnea related to local invasion; distal metastasis and lymphadenopathy at the time of diagnosis is rare. Pericardial involvement in mesothelioma is related to direct invasion of the tumor. We here present a 71 year-old-male who presented with pleuritic chest pain and dyspnea, noted to have diffuse ST-segment elevation in EKG and cardiac tamponade physiology on 2D echocardiogram in who imaging subsequently revealed left upper lung mesothelioma. A pericardial window was created following which tamponade resolved. The pericardial biopsy did not show any mesothelioma cells or fibrous plaques. Computer tomography revealed regional lymphadenopathy in the chest. Disrupted cardiac lymphatic flow due to tumor mesothelioma induced lymphadenopathy is likely cause of the cardiac tamponade in this patient. This is the second ever reported case of pleural mesothelioma without a direct pericardial invasion that presented with cardiac tamponade.

AB - The cortex, hippocampus, and striatum support dissociable forms of memory. While each of these regions contains specialized circuitry supporting their respective functions, all structure their activities across time with delta, theta, and gamma rhythms. We review how these oscillations are generated and how they coordinate distinct memory systems during encoding, consolidation, and retrieval. First, gamma oscillations occur in all regions and coordinate local spiking, compressing it into short population bursts. Second, gamma oscillations are modulated by delta and theta oscillations. Third, oscillatory dynamics in these memory systems can operate in either a 'slow' or 'fast' mode. The slow mode happens during slow-wave sleep (SWS) and is characterized by large irregular activity in the hippocampus and delta oscillations in cortical and striatal circuits. The fast mode occurs during active waking and REM and is characterized by theta oscillations in the hippocampus and its targets, along with gamma oscillations in the rest of cortex. In waking, the fast mode is associated with the efficacious encoding and retrieval of declarative and procedural memories. Theta and gamma oscillations have the similar relationships with encoding and retrieval across multiple forms of memory and brain regions, despite regional differences in microcircuitry and information content. Differences in the oscillatory coordination of memory systems during sleep might explain why the consolidation of some forms of memory is sensitive to SWS, while others depend on REM. In particular, theta oscillations appear to support the consolidation of certain types of procedural memories during REM, while delta oscillations during SWS seem to promote declarative and procedural memories. PMID- 30294456 TI - Data for decision making: using a dashboard to strengthen routine immunisation in Nigeria. AB - Availability of reliable data has for a long time been a challenge for health programmes in Nigeria. Routine immunisation (RI) data have always been characterised by conflicting coverage figures for the same vaccine across different routine data reporting platforms. Following the adoption of District Health Information System version 2 (DHIS2) as a national electronic data management platform, the DHIS2 RI Dashboard Project was initiated to address the absence of some RI-specific indicators on DHIS2. The project was also intended to improve visibility and monitoring of RI indicators as well as strengthen the broader national health management information system by promoting the use of routine data for decision making at all governance levels. This paper documents the process, challenges and lessons learnt in implementing the project in Nigeria. A multistakeholder technical working group developed an implementation framework with clear preimplementation; implementation and postimplementation activities. Beginning with a pilot in Kano state in 2014, the project has been scaled up countrywide. Nearly 34 000 health workers at all administrative levels were trained on RI data tools and DHIS2 use. The project contributed to the improvement in completeness of reports on DHIS2 from 53 % in first quarter 2014 to 81 % in second quarter 2017. The project faced challenges relating to primary healthcare governance structures at the subnational level, infrastructure and human resource capacity. Our experience highlights the need for early and sustained advocacy to stakeholders in a decentralised health system to promote ownership and sustainability of a centrally coordinated systems strengthening initiative.

AB - India implemented larger 85% pictorial health warnings on all tobacco products from 1 April 2016. However, to remove the last bit of glamour and attraction from the tobacco packs, it must now embrace plain packaging. Plain packaging prevents tobacco packs from carrying the tobacco industry brand imagery as mobile billboards. Postimplementation of larger 85% pictorial health warnings on all tobacco products, this analysis was undertaken to assess the feasibility of plain packaging as the next logical tobacco control policy measure in India. As part of this analysis, the research team reviewed the available literature on legal and policy challenges to plain packaging as a tobacco control policy initiative for India. Literature from 2010 to 2016 in English language was reviewed, which reveals that, India has taken several preparatory steps implemented by other countries like Australia and the UK that have introduced plain packaging, for example, stronger smoke-free laws, ban on tobacco advertising, promotion and sponsorship, increase in taxes and a report from civil society task force on plain packaging. The trade and investment agreements signed by India are also within the international trade norms relating to public health. A Private Member's Bill on plain packaging is also pending in the Parliament of India. Other potential challenges against such policy decision, for example, freedom of trade, right to property, violation of competition law and other laws including consumer protection laws, were found unsubstantiated by the research team. Plain packaging is the next logical step for tobacco control policy in India. PMID- 30294459 TI - Time to include burden of surgical injuries after disasters in the Global Surgery agenda? An assessment of DALYs and averted burden by surgery after the 2008 Wenchuan earthquake. AB - Unlike other disasters, injury rates after earthquakes are still on the rise at a global scale. With an estimated one million people injured by earthquakes in the last decade, the burden of injury is considerable. Importantly, the surgical procedures carried out by healthcare facilities are capable to avert part of this burden. Yet both burdens remain unquantified using understandable metrics. We explored in this analysis a method to calculate them using disability-adjusted life years (DALYs), an internationally accepted measure expressing years of healthy life lost due to a health condition. We used data from a large standardised hospital database of earthquake-related injuries with complete information on International Classification of Diseases for injury and surgical procedures, sex and age information. DALYs and averted DALYs were calculated by injury types and per patient using disability weights available in the literature and expert opinion. We also suggested how DALYs might be further converted into an economic measure using approaches in the published literature. We estimated 10 397 DALYs as the earthquake surgical-injury burden produced in 1861 hospitalised patients treated in a single hospital (on average, 5.6 DALYs per patient). Our study also assessed that 4379 DALYs, or 2.4 DALYs per patient, were averted by surgery (42%). In economic terms, DALY losses amounted to US$36.1 million, from which US$15.2 million were averted by surgery in our case study. We urge to systematically estimate these impacts through improvements in the routine reporting of injury diagnoses and surgical procedures by health systems, potentially improving prevention policies and resource allocation to healthcare facilities.

PMID- 30294460 TI - Health system governance following devolution: comparing experiences of decentralisation in Kenya and Indonesia. AB - Introduction: Devolution reforms in Indonesia and Kenya have brought extensive changes to governance structures and mechanisms for financing and delivering healthcare. Community health approaches can contribute towards attaining many of devolution's objectives, including community participation, responsiveness, accountability and improved equity. We set out to examine governance in two countries at different stages in the devolution journey: Indonesia at 15 years postdevolution and Kenya at 3 years. Methods: We collected qualitative data across multiple levels of the health system in one district in Indonesia and ten counties in Kenya, through 80 interviews and six focus group discussions (FGD) in Indonesia and 269 interviews and 14 FGDs in Kenya. Qualitative data were digitally recorded, transcribed and coded before thematic framework analysis. Common themes between contexts were identified inductively and deductively, and similarities and differences critically analysed during an inter-country analysis workshop. Results: Following devolution both Indonesia and Kenya experienced similar challenges ensuring good governance for health. Devolution reforms transformed power relationships, increasing responsibilities at subnational levels and introducing opportunities for citizen participation. In both contexts, the impact of these mechanisms has been undermined by insufficiently clear guidance; failure to address pre-existing negative contextual norms and practices varied decision-maker values, limited priority-setting capacity and limited genuine community accountability. As a consequence, priorities in both contexts are too often placed on curative rather than preventive health services. Conclusion: We recommend consideration of increased intersectoral actions that address social determinants of health, challenge negative norms and practices and place emphasis on community-based primary health services.

AB - Introduction: Effective translational research requires engagement and collaboration between communities, researchers, and practitioners. We describe a community scientist academy (CSA) developed at the suggestion of our CTSA's community advisory board to engage and capacitate community members by 1) increasing community members' and patients' understanding about the research process and 2) increasing their access to opportunities to influence and participate in research. A joint CTSA/community planning committee developed this 8-hour workshop including sessions on: 1) research definitions and processes; 2) study design; 3) study implementation; and 4) ways to get involved in research. The workshop format includes interactive exercises, content slides and videos, and researcher and community presenters. Methods: Community-based information sessions allowed assessment of community interest before piloting. Two pilots of the CSA were conducted with community members and patients. Participant data and a pre/post knowledge and feedback survey provides evaluation data. Results: The pilot included 24 diverse participants, over half of whom had not previously participated in research. Evaluation data suggest knowledge gains. Post- CSA, one third have reviewed CTSA pilot grants and over 80% want to attend further training. Conclusions: The CSA can demystify the research process for those underrepresented in research and facilitate their engagement and influence within CTSAs. PMID- 30294467 TI - Guidelines for evaluation and management of cerebral collateral circulation in ischaemic stroke 2017. AB - Collateral circulation plays a vital role in sustaining blood flow to the ischaemic areas in acute, subacute or chronic phases after an ischaemic stroke or transient ischaemic attack. Good collateral circulation has shown protective effects towards a favourable functional outcome and a lower risk of recurrence in stroke attributed to different aetiologies or undergoing medical or endovascular treatment. Over the past decade, the importance of collateral circulation has attracted more attention and is becoming a hot spot for research. However, the diversity in imaging methods and criteria to evaluate collateral circulation has hindered comparisons of findings from different cohorts and further studies in exploring the clinical relevance of collateral circulation and possible methods to enhance collateral flow. The statement is aimed to update currently available evidence and provide evidence-based recommendations regarding grading methods for collateral circulation, its significance in patients with stroke and methods under investigation to improve collateral flow. PMID- 30294468 TI - Contribution of diffusion, perfusion and functional MRI to the disconnection hypothesis in subcortical vascular cognitive impairment. AB - Vascular cognitive impairment (VCI) describes all forms of cognitive impairment caused by any type of cerebrovascular disease. Early identification of VCI is quite difficult due to the lack of both sensitive and specific biomarkers. Extensive damage to the white matter tracts, which connect the cortical and subcortical regions, has been shown in subcortical VCI (SVCI), the most common subtype of VCI that is caused by small vessel disease. Two specific MRI sequences, including diffusion tensor imaging (DTI) and functional MRI (fMRI), have emerged as useful tools for identifying subtle white matter changes and the intrinsic connectivity between distinct cortical regions. This review describes the advantages of these two modalities in SVCI research and the current DTI and fMRI findings on SVCI. Using DTI technique, a variety of studies found that white matter microstructural damages in the anterior and superior areas are more specific to SVCI. Similarly, functional brain abnormalities detected by fMRI have also been mainly shown in anterior brain areas in SVCI. The characteristic distribution of brain abnormalities in SVCI interrupts the prefrontal-subcortical loop that results in cognitive impairments in particular domains, which further confirms the 'disconnection syndrome' hypothesis. In addition, another MRI technique, arterial spin labelling (ASL), has been used to describe the disconnection patterns in a variety of conditions by measuring cerebral blood flow. The role of the ASL technique in SVCI research is also assessed. Finally, the review proposes the application of multimodality fusion in the investigation of SVCI pathogenesis. PMID- 30294469 TI - Stenting for intracranial stenosis: potential future for the prevention of disabling or fatal stroke. AB - Intracranial stenosis is a common cause of ischaemic strokes, in particular, in the Asian, African and Hispanic populations. The randomised multicentre study Stenting and Aggressive Medical Management for the Prevention of Recurrent stroke in Intracranial Stenosis (SAMMPRIS) showed 14.7% risk of stroke or death in the stenting group versus 5.8% in the medical group at 30 days, and 23% in the stenting group versus 15% in the medical group at a median follow-up of 32.4 months. The results demonstrated superiority of medical management over stenting and have almost put the intracranial stenting to rest in recent years. Of note, 16 patients (7.1%) in the stenting group had disabling or fatal stroke within 30 days mostly due to periprocedural complications as compared with 4 patients (1.8%) in the medical group. In contrast, 5 patients (2.2%) in the stenting group and 14 patients (6.2%) in the medical group had a disabling or fatal stroke beyond 30 days, indicating significant benefit of stenting if periprocedural complications can be reduced. Recently, the results of the Chinese Angioplasty and Stenting for Symptomatic Intracranial Severe Stenosis trial and the Wingspan Stent System Post Market Surveillance Study (WEAVE trial) showed 2%-2.7% periprocedural complications. It is time to evaluate the role of intracranial stenting for the prevention of disabling or fatal stroke. PMID- 30294470 TI - Registry report on prediction by Pocock cardiovascular score of cerebral microemboli acutely following carotid endarterectomy. AB - Background: Cerebral microemboli may lead to ischaemic neurological complications after carotid endarterectomy (CEA). The association between classical cardiovascular risk factors and acute cerebral microemboli following carotid surgery has not been studied. The aim of this study was to explore whether an established cardiovascular risk score (Pocock score) predicts the presence of cerebral microemboli acutely after CEA. Subjects and methods: Pocock scores were assessed for the 670 patients from the Carotid Surgery Registry (age 71+/-1 (SEM) years, 474 (71%) male, 652 (97%) Caucasian) managed from January 2002 to December 2012 in the Regional Vascular Centre at University Hospitals Coventry and Warwickshire NHS Trust, which serves a population of 950 000. CEA was undertaken in 474 (71%) patients for symptomatic carotid stenosis and in 196 (25%) asymptomatic patients during the same period. 74% of patients were hypertensive, 71% were smokers and 49% had hypercholesterolaemia. Results: A high Pocock score (>=2.3%) was significantly associated with evidence of cerebral microemboli acutely following CEA (P=0.039, Mann-Whitney (MW) test). A Pocock score (>=2.3%) did not predict patients who required additional antiplatelet therapy (microemboli signal (MES) rate >50 hour-1: P=0.164, MW test). Receiver operating characteristic analysis also showed that the Pocock score predicts acute postoperative microemboli (area under the curve (AUC) 0.546, 95% CI 0.502 to 0.590, P=0.039) but not a high rate of postoperative microemboli (MES >50 hour-1: AUC 0.546, 95% CI 0.482 to 0.610, P=0.164). A Pocock score >=2.3% showed a sensitivity of 74% for the presence of acute postoperative cerebral microemboli. A Pocock score >=2.3% also showed a sensitivity of 77% and a negative predictive value of 90% for patients who developed a high microembolic rate >50 hour-1 after carotid surgery. Conclusion: These findings demonstrate that the Pocock score could be used as a clinical tool to identify patients at high risk of developing acute postoperative microemboli. PMID- 30294471 TI - Post-stroke mRNA expression profile of MMPs: effect of genetic deletion of MMP 12. AB - Background and purpose: Recent reports from our laboratory demonstrated the post ischaemic expression profile of various matrix metalloproteinases (MMPs) in rats and the detrimental role of MMP-12 in post-stroke brain damage. We hypothesise that the post-stroke dysregulation of MMPs is similar across species and that genetic deletion of MMP-12 would not affect the post-stroke expression of other MMPs. We tested our hypothesis by determining the pre-ischaemic and post ischaemic expression profile of MMPs in wild-type and MMP-12 knockout mice. Methods: Focal cerebral ischaemia was induced in wild-type and MMP-12 knockout mice by middle cerebral artery occlusion procedure by insertion of a monofilament suture. One hour after ischaemia, reperfusion was initiated by removing the monofilament. One day after reperfusion, ischaemic brain tissues from various groups of mice were collected, and total RNA was isolated and subjected to cDNA synthesis followed by PCR analysis. Results: Although the post-stroke expression profile of MMPs in the ischaemic brain of mice is different from rats, there is a clear species similarity in the expression of MMP-12, which was found to be predominantly upregulated in both species. Further, the post-stroke induction or inhibition of various MMPs in MMP-12 knockout mice is different from their respective expression profile in wild-type mice. Moreover, the brain mRNA expression profile of various MMPs in MMP-12 knockout mice under normal conditions is also different to their expression in wild-type mice. Conclusions: In the ischaemic brain, MMP-12 upregulates several fold higher than any other MMP. Mice derived with the genetic deletion of MMP-12 are constitutive and have altered MMP expression profile both under normal and ischaemic conditions. PMID- 30294472 TI - Association between admission haematocrit and mortality among men with acute ischaemic stroke. AB - Objective: Anaemia is associated with higher mortality among patients with non stroke cardiovascular conditions; less is known regarding the relationship between anaemia and mortality among patients with acute ischaemic stroke. Methods: Medical records were abstracted for n=3965 veterans from 131 Veterans Health Administration facilities who were admitted with ischaemic stroke in fiscal year 2007. Haematocrit values within 24 hours of admission were classified as <=27%, 28%-32%, 33%-37%, 38%-42%, 43%-47% or >=48%. Multivariate logistic regression was used to examine the relationship between anaemia and in-hospital, 30-day, 6-month and 1-year mortality, adjusting for age, medical comorbidities, modified Acute Physiology and Chronic Health Evaluation-III and stroke severity. Impact factors were calculated to standardise comparisons between haematocrit tier and other covariates. Results: Among n=3750 patients included in the analysis, the haematocrit values were <=27% in 2.1% (n=78), 28%-32% in 6.2% (n=234), 33%-37% in 17.9% (n=670), 38%-42% in 36.4% (n=1366), 43%-47% in 28.2% (n=1059) and >=48% in 9.1% (n=343). Patients with haematocrit <=27%, compared with patients in the 38%-42% range, were more likely to have died across all follow-up intervals, with statistically significant adjusted ORs (aORs) ranging from 2.5 to 3.5. Patients with polycythaemia (ie, haematocrit >=48%) were at increased risk of in-hospital mortality (aOR=2.9; 95% CI 1.4 to 6.0), compared with patients with mid-range admission haematocrits. Pronounced differences between patients receiving and not receiving blood transfusion limited our ability to perform a propensity analysis. Impact factors in the 1-year mortality model were 0.46 (severe anaemia), 0.06 (cancer) and 0.018 (heart disease). Conclusions: Anaemia is independently associated with an increased risk of death throughout the first year post stroke; high haematocrit is associated with early poststroke mortality. Severe anaemia is associated with 1-year mortality to a greater degree than cancer or heart disease. These data cannot address the question of whether interventions targeting anaemia might improve patient outcomes. PMID- 30294473 TI - Procedural complexity independent of P2Y12 reaction unit (PRU) values is associated with acute in situ thrombosis in Pipeline flow diversion of cerebral aneurysms. AB - Background: Acute in situ thrombosis is an ischaemic phenomenon during Pipeline embolisation device (PED) procedures with potentially high morbidity and mortality. There is controversy regarding the role of platelet function testing with P2Y12 assay as a predictor of intraprocedural thromboembolic events. There is limited knowledge on whether procedural complexity influences these events. Methods: Data were collected retrospectively on 742 consecutive PED cases at a single institution. Patients with intraprocedural acute thrombosis were compared with patients without these events. Results: A cohort of 37 PED cases with acute in situ thrombosis (mean age 53.8 years, mean aneurysm size 8.4 mm) was matched with a cohort of 705 PED cases without intraprocedural thromboembolic events (mean age 56.4 years, mean aneurysm size 6.9 mm). All patients with in situ thrombosis received intra-arterial and/or intravenous abciximab. The two groups were evenly matched in patient demographics, previous treatment/subarachnoid hemorrhage (SAH) and aneurysm location. There was no statistical difference in postprocedural P2Y12 reaction unit (PRU) values between the two groups, with a mean of 156 in the in situ thrombosis group vs 148 in the control group (p=0.5894). Presence of cervical carotid tortuosity, high cavernous internal carotid artery grade, need for multiple PED and vasospasm were not significantly different between the two groups. The in situ thrombosis group had statistically significant longer fluoroscopy time (60.4 vs 38.4 min, p<0.0001), higher radiation exposure (3476 vs 2160 mGy, p<0.0001), higher rates of adjunctive coiling (24.3% vs 8.37%, p=0.0010) and higher utilisation of balloon angioplasty (37.8% vs 12.2%, p<0.0001). Clinically, the in situ thrombosis cohort had higher incidence of major and minor stroke, intracerebral haemorrhage and length of stay. Conclusions: Predictors of procedural complexity (higher radiation exposure, longer fluoroscopy time, adjunctive coiling and need for balloon angioplasty) are associated with acute thrombotic events during PED placement, independent of PRU values.

AB - Background and purpose: A multicentre prospective registry study of individually tailored stenting for a patient with symptomatic intracranial atherosclerotic stenosis (ICAS) combined with poor collaterals in China showed that the short term safety and efficacy of stenting was acceptable. However, it remained uncertain whether the low event rate could be of a long term. We reported the 1 year outcome of this registry study to evaluate the long-term efficacy of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals. Methods: Patients with symptomatic ICAS caused by 70%-99% stenosis located at the intracranial internal carotid, middle cerebral, intracranial vertebral or basilar arteries combined with poor collaterals were enrolled. Balloon-mounted stent or balloon plus self-expanding stent were selected based on the ease of vascular access and lesion morphology determined by the operators. The primary outcome was the rate of 30-day stroke, transient ischaemic attack and death, and 12-month ischaemic stroke within the same vascular territory, haemorrhagic stroke and vascular death after stenting. Results: From September 2013 to January 2015, 300 patients (ages 58.3+/-9.78 years) were recruited. Among them, 159 patients were treated with balloon-mounted stent and 141 with balloon plus self-expanding stent. During the 1-year follow up, 25 patients had a primary end point event. The probability of primary outcome at 1 year was 8.1% (95% CI 5.3% to 11.7%). In 76 patients with digital subtraction angiography follow-up, 27.6% (21/76) had re-stenosis >=50% and 18.4% (14/76) had re-stenosis >=70%. No baseline characteristic was associated with the primary outcome. Conclusion: The event rate remains low over 1 year of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals. Further randomised trial of comparing individually tailored stenting with best medical therapy is needed. Trial registration number: NCT01968122; Results. PMID- 30294477 TI - New Report of Three Unrecorded Species in Trichoderma harzianum Species Complex in Korea. AB - The genus Trichoderma (Hypocreaceae, Ascomycota) consists of globally distributed fungi. Among them, T. harzianum, one of the most commonly collected Trichoderma species, had been known as a polyphyletic or aggregate species. However, a total of 19 species were determined from the polyphyletic groups of T. harzianum. Thus, we explored Korean "T. harzianum" specimens that were collected in 2013-2014. These specimens were re-examined based on a recent study with translate elongation factor 1-alpha (EF1alpha) sequences to reveal cryptic Trichoderma species in Korea. As a result, four different species, T. afroharzianum, T. atrobruneum, T. pyramidale, and T. harzianum, were identified. Except T. harzianum, the other three species have not been reported in Korea. In this work, we describe these species and provide figures. PMID- 30294478 TI - New Species and New Record of Genus Chrysothrix (Chrysotrichaceae, Arthoniales) from South Korea and Chile.

PMID- 30294479 TI - Taxonomy of the Golovinomyces cynoglossi Complex (Erysiphales, Ascomycota) Disentangled by Phylogenetic Analyses and Reassessments of Morphological Traits. AB - The name Golovinomyces cynoglossi s. lat. is traditionally applied to a complex of morphologically similar powdery mildews on hosts of the plant family Boraginaceae. The current species-level taxonomy within this complex is ambiguous due to the lack of phylogenetic examinations. The present study applied phylogenetic methods to clarify the taxonomy of G. cynoglossi s. lat. Phylogenetic analysis of rDNA ITS sequences retrieved from Asian, European and North American specimens revealed that G. cynoglossi s. lat. collections from different hosts involved several species in five clearly separated lineages. Clade I consists primarily of Golovinomyces cynoglossi s. str. on Cynoglossum. Clade III consists of Golovinomyces sequences retrieved from the host genera Symphytum and Pulmonaria. The taxa within clade III are now assigned to G. asperifoliorum comb. nov. Clade V encompasses G. cynoglossi s. lat. on the host genera Bothriospermum, Buglossoides, Echium, Myosotis, and Trigonotis. The taxa within clade V are now assigned to G. asperifolii comb. nov. The species concerned in this study were lecto- and epitypified to stabilize their nomenclature.

AB - The order Mucorales, the largest in number of species within the Mucoromycotina, comprises typically fast-growing saprotrophic fungi. During a study of the fungal diversity of undiscovered taxa in Korea, two novel mucoralean strains, CNUFC-GWD3 9 and CNUFC-EGF1-4, were isolated from specific habitats including freshwater and fecal samples, respectively. On the basis of their morphological characteristics and sequence analyses of internal transcribed spacer and large subunit ribosomal DNA, the CNUFC-GWD3-9 and CNUFC-EGF1-4 isolates were confirmed to be Gilbertella persicaria and Pilobolus crystallinus, respectively. It is ecologically, pathologically, and mycologically significant to find such rare zygomycetous fungi in such specific habitats. PMID- 30294483 TI - LAMMER Kinase Lkh1 Is an Upstream Regulator of Prk1-Mediated Non-Sexual Flocculation in Fission Yeast. AB - The cation-dependent galactose-specific flocculation activity of the Schizosaccharomyces pombe null mutant of lkh1 +, the gene encoding LAMMER kinase homolog, has previously been reported by our group. Here, we show that disruption of prk1 +, another flocculation associated regulatory kinase encoding gene, also resulted in cation-dependent galactose-specific flocculation. Deletion of prk1 increased the flocculation phenotype of the lkh1 + null mutant and its overexpression reversed the flocculation of cells caused by lkh1 deletion. Transcript levels of prk1 + were also decreased by lkh1 + deletion. Cumulatively, these results indicate that Lkh1 is one of the negative regulators acting upstream of Prk1, regulating non-sexual flocculation in fission yeast. PMID- 30294484 TI - The Major Postharvest Disease of Onion and Its Control with Thymol Fumigation During Low-Temperature Storage. AB - Onion (Allium cepa L.) is one of the major vegetable crops in Korea that are damaged and lost by pathogenic fungal infection during storage due to a lack of proper storage conditions. The aim of this study was to determine an appropriate control measure using thymol to increase the shelf life of onions. To control fungal infections that occur during low-temperature storage, it is necessary to identify the predominant fungal pathogens that appear in low-temperature storage houses. Botrytis aclada was found to be the most predominant fungal pathogen during low-temperature storage. The antifungal activity of the plant essential oil thymol was tested and compared to that of the existing sulfur treatments. B. aclada growth was significantly inhibited up to 16 weeks with spray treatments using a thymol solution. To identify an appropriate method for treating onions in a low-temperature storage house, thymol was delivered by two fumigation treatment methods, either by heating it in the granule form or as a solution at low temperature storage conditions (in vivo). We confirmed that the disease severity was reduced up to 96% by fumigating thymol solution compared to the untreated control. The efficacy of the fumigation of thymol solution was validated by testing onions in a low-temperature storage house in Muan, Jeollanam-do. Based on these results, the present study suggests that fumigation of the thymol solution as a natural preservative and fungicide can be used as an eco-friendly substitute for existing methods to control postharvest disease in long-term storage crops on a commercial scale. PMID- 30294482 TI - Influence of Temperature on the Bacterial Community in Substrate and Extracellular Enzyme Activity of Auricularia cornea. AB - Temperature is an important environmental factor that can greatly influence the cultivation of Auricularia cornea. In this study, lignin peroxidase, laccase, manganese peroxidase, and cellulose in A. cornea fruiting bodies were tested under five different temperatures (20 degrees C, 25 degrees C, 30 degrees C, 35 degrees C, and 40 degrees C) in three different culture periods (10 days, 20 days and 30 days). In addition, the V4 region of bacterial 16S rRNA genes in the substrate of A. cornea cultivated for 30 days at different temperatures were sequenced using next-generation sequencing technology to explore the structure and diversity of bacterial communities in the substrate. Temperature and culture days had a significant effect on the activities of the four enzymes, and changes in activity were not synchronized with changes in temperature and culture days. Overall, we obtained 487,694 sequences from 15 samples and assigned them to 16 bacterial phyla. Bacterial community composition and structure in the substrate changed when the temperature was above 35 degrees C. The relative abundances of some bacteria were significantly affected by temperature. A total of 35 genera at five temperatures in the substrate were correlated, and 41 functional pathways were predicted in the study. Bacterial genes associated with the membrane transport pathway had the highest average abundance (16.16%), and this increased at 35 degrees C and 40 degrees C. Generally, different temperatures had impacts on the physiological activity of A. cornea and the bacterial community in the substrate; therefore, the data presented herein should facilitate cultivation of A. cornea.

Moench) has gained more popularity as an economically significant plant for its nutritional and medicinal value, especially in China. During 2014-2016, the root disease of okra was discovered in four okra commercial fields surveyed in China. A fungul was isolated from the infected tissues, and was identified by Verticillium dahliae based on morphological characteristics. Pathogenicity test demonstrated that the fungus was pathogenic on okra, and fulfilled Koch's postulates. The analysis of three sequences revealed 99-100% identity with the reported V. dahliae strain in GenBank. Neighbor-joining analysis of the gene sequences revealed that the representative isolates were clustered with V. dahliae. To the best of our knowledge, this is the first report of Verticillium wilt of okra in China.

AB - In an ongoing survey of Korean indigenous fungi, two fungal strains (KNU16-74 and KNU16-99) belonging to the genus Chrysosporium were isolated from field soil in Gyeongnam, Korea. Morphological characterization and phylogenetic analysis using sequence of the internal transcribed spacer regions were carried out to confirm its precise identification. These strains were identified as Chrysosporium indicum (KNU16-74) and Chrysosporium fluviale (KNU16-99). To examine the keratin degradation efficiency of these two fungal species, human hair strands were incubated with fungus culture. Results revealed that these two fungal species have the ability to degrade keratin substrate. This is the first report of these two species in Korea.

Among 113 candidates, 34 strains that colored the inoculated potato dextrose agar medium were selected. They were cultured in potato dextrose broth and extracted with ethanol. The productivity, functionality (radical-scavenging activities), and color information (CIELAB values) of the pigment extracts were measured. Five species produced intense yellowish pigments, and two produced intense reddish pigments that ranked the highest in terms of absorbance units produced per day. The pigment extracts of Penicillium miczynskii, Sanghuangporus baumii, Trichoderma sp. 1, and Trichoderma afroharzianum exhibited high radical scavenging activity. However, the S. baumii extract showed moderate toxicity in the acute toxicity test, which limits the industrial application of this pigment. In conclusion, P. miczynskii KUC1721, Trichoderma sp. 1 KUC1716, and T. afroharzianum KUC21213 were the best fungal candidates to be industrial producers of safe, functional water-soluble pigments. PMID- 30294489 TI - Timing of Fusarium Head Blight Infection in Rice by Heading Stage. AB - Fusarium graminearum causes the devastating plant disease Fusarium head blight and produces mycotoxins on small cultivated grains. To investigate the timeframe of F. graminearum infection during rice cultivation, a spore suspension of F. graminearum was applied to the rice cultivars Dongjin 1 and Nampyeongbyeo before and after the heading stage. The disease incidence rate was the highest (50%) directly after heading, when the greatest number of flowers were present, while only 10% of the rice infected 30 days after heading showed symptoms. To understand the mechanism of infection, an F. graminearum strain expressing green fluorescent protein (GFP) was inoculated, and the resulting infections were visually examined. Spores were found in all areas between the glume and inner seed, with the largest amount of GFP detected in the aleurone layer. When the inner part of the rice seed was infected, the pathogen was mainly observed in the embryo. These results suggest that F. graminearum migrates from the anthers to the ovaries and into the seeds during the flowering stage of rice. This study will contribute to uncovering the infection process of this pathogen in rice. PMID- 30294490 TI - Effect of Temperature and Relative Humidity on Growth of Aspergillus and Penicillium spp. and Biocontrol Activity of Pseudomonas protegens AS15 against Aflatoxigenic Aspergillus flavus in Stored Rice Grains. AB - In this study, we evaluated the effect of different temperatures (10, 20, 30, and 40 degrees C) and relative humidities (RHs; 12, 44, 76, and 98%) on populations of predominant grain fungi (Aspergillus candidus, Aspergillus flavus, Aspergillus fumigatus, Penicillium fellutanum, and Penicillium islandicum) and the biocontrol activity of Pseudomonas protegens AS15 against aflatoxigenic A. flavus KCCM 60330 in stored rice. Populations of all the tested fungi in inoculated rice grains were significantly enhanced by both increased temperature and RH. Multiple linear regression analysis revealed that one unit increase of temperature resulted in greater effects than that of RH on fungal populations. When rice grains were treated with P. protegens AS15 prior to inoculation with A. flavus KCCM 60330, fungal populations and aflatoxin production in the inoculated grains were significantly reduced compared with the grains untreated with strain AS15 regardless of temperature and RH (except 12% RH for fungal population). In addition, bacterial populations in grains were significantly enhanced with increasing temperature and RH, regardless of bacterial treatment. Higher bacterial populations were detected in biocontrol strain-treated grains than in untreated control grains. To our knowledge, this is the first report showing consistent biocontrol activity of P. protegens against A. flavus population and aflatoxin production in stored rice grains under various environmental conditions of temperature and RH. PMID- 30294491 TI - Laboratory testing of a shuttle car canopy air curtain for respirable coal mine dust control. AB - Canopy air curtain (CAC) technology has been developed by the National Institute for Occupational Safety and Health (NIOSH) for use on continuous miners and subsequently roof bolting machines in underground coal mines to protect operators of these machines from overexposure to respirable coal mine dust. The next logical progression is to develop a CAC for shuttle cars to protect operators from the same overexposures. NIOSH awarded a contract to Marshall University and J.H. Fletcher to develop the shuttle car CAC. NIOSH conducted laboratory testing to determine the dust control efficiency of the shuttle car CAC. Testing was conducted on two different cab configurations: a center drive similar to that on a Joy 10SC32AA cab model and an end drive similar to that on a Joy 10SC32AB cab model. Three different ventilation velocities were tested-0.61, 2.0, 4.3 m/s (120, 400, and 850 fpm). The lowest, 0.61 m/s (120 fpm), represented the ventilation velocity encountered during loading by the continuous miner, while the 4.3 m/s (850 fpm) velocity represented ventilation velocity airflow over the shuttle car while tramming against ventilation airflow. Test results showed an average of the dust control efficiencies ranging from 74 to 83% for 0.61 m/s (120 fpm), 39%-43% for 2.0 m/s (400 fpm), and 6%-16% for 4.3 m/s (850 fpm). Incorporating an airflow spoiler to the shuttle car CAC design and placing the CAC so that it is located 22.86 cm (9 in.) forward of the operator improved the dust control efficiency to 51%-55% for 4.3 m/s (850 fpm) with minimal impact on dust control efficiencies for lower ventilation velocities. These laboratory tests demonstrate that the newly developed shuttle car CAC has the potential to successfully protect shuttle car operators from coal mine respirable dust overexposures. PMID- 30294492 TI - Infrared thermography brain mapping surveillance in vascular neurosurgery for anterior communicating artery aneurysm clipping. AB - Background: Infrared thermography (IT) is a noninvasive, real-time diagnostic method that requires no contact with the patient and has a broad spectrum of potential applications in neurosurgery. It has been previously demonstrated the high sensitivity and specificity that IT has to detect brain blood flow changes. Case Description: The case is based on a 64-year-old diabetic and hypertensive male, to whom an anterior communicating artery (ACoA) incidental aneurysm was discovered. We performed the basal infrared thermography mapping (ITM) and immediately after the transitory clip placement in both A1 segments of the anterior cerebral artery (A1-ACA), we performed a second ITM of the exposed brain cortex. After the definitive clip placement in the neck of the ACoA aneurysm, we removed the transitory clips of both A1-ACA and performed a third ITM of the cortical surface, without finding any cortical cooling or significative temperature differences (?t) compared to the basal ITM. The postoperatory computed tomography (CT) and angio-CT did not show any ischemic damage and confirmed the accurate aneurysm clipping. Conclusions: The ITM seems to be a real time, safe, and useful brain mapping method to identify different temperature zones and temperature dispersion gradients in the human brain cortex. More studies are needed to evaluate the potential applications of IT mapping of the human brain and its use in neurosurgery and vascular neurosurgery. PMID- 30294494 TI - Compartment syndrome of lumbar paraspinal musculature after percutaneous pedicle screw fixation. AB - Background: Compartment syndromes have been reported in nearly every anatomical area of the extremities. Similarly, in the lumbar spine, there is a risk of a compartment syndrome following either direct or indirect injury to the paraspinal muscles. In this study, we present a case of lumbar paraspinal compartment syndrome after percutaneous pedicle screw fixation for a spine fracture. Case Description: A 27-year-old obese female sustained a fall and an L1 fracture. Her neurological examination was normal. She underwent a minimally invasive percutaneous posterior pedicle screw fixation from T12 to L2 to stabilize the L1 fracture. Postoperatively, the patient developed hypoesthesia in the back, and sterile serous wound discharge. Because of the persistent discharge, an open debridement was performed that revealed multiple cavities within the necrotic avascular paraspinal musculature. Once these were completely excised, the wounds healed uneventfully. Conclusion: Patients undergoing minimally invasive posterior thoracolumbar (TL) pedicle screw fixation can develop a compartment syndrome involving the TL paraspinal musculature. This case highlights the need for early consideration of a compartment syndrome when patients develop persistent sterile discharge after spine surgery. In this case, urgent decompression prevented any long-term sequelae. PMID- 30294493 TI - Fusiform aneurysms: A review from its pathogenesis to treatment options. AB - Background: This study aims to present the most important considerations when it comes to patients features, clinical presentation, localization, and morphology of the aneurysm and the treatments outcomes of the fusiform aneurysms. Methods: We performed a literature review using PubMed. The search was limited to the studies published in English, from 2003 to 2017. Results: The studies analyzed that showed data about the patient features, clinical presentation, the aneurysm localization, morphology, and pathogenesis didn't present much divergence. The surgical and the endovascular approach showed similar treatments outcomes. The reconstructive techniques seem to be safer than the deconstructive. The flow diversion is a technique that showed great results. Conclusion: Most of the patients are men, younger than 50 years old, pediatric patients are the most affected. Surgical procedures still have an important place in this field. Reconstructive and deconstructive techniques are both effective; the reconstructive techniques are possibly safer than deconstructive techniques. The most important feature of an aneurysm to predict a bad prognose is to determine if the aneurysm is ruptured. The reconstructive EVT accompanied by dual antiplatelet after and before the procedure showed the best results to treat the basilar fusiform aneurysms. Deconstructive treatment including posterior inferior cerebellar artery occlusion should be considered. PMID- 30294495 TI - Myxopapillary ependymoma with anaplastic features: A case report with review of the literature. AB - Background: Myxopapillary ependymoma (MPE) with anaplastic features is extremely rare, with only three case reports in the literature. Case Description: We report the case of a MPE with anaplastic features in a 24-year-old female who presented with a dominant lumbar mass along with intracranial and sacral metastases. Upon gross total resection of the dominant tumor located at L2-L3, it appeared to arise from the filum terminale, and had a solid component in addition to soft or necrotic areas. Histologically, the tumor was composed of the two classic components of MPE: (1) low-grade ependymal cells surrounding blood vessels, producing the papillary appearance and (2) perivascular myxoid material between blood vessels and ependymal cells, creating the myxopapillary appearance. The high-grade anaplastic component showed hypercellularity, brisk mitotic rate, and vascular proliferation, with frequent pleomorphic cells and atypical mitotic figures. It was positive for vimentin and glial fibrillary acidic protein (GFAP); negative for epithelial membrane antigen (EMA), CAM5.2, creatine kinase 7 (CK7), CK20; and the MIB-1 index (Ki-67) was 8-38%. Ten months after initial resection, follow-up magnetic resonance imaging revealed new lesions in (1) the hypothalamus, (2) the left pons, and (3) the left medial temporal lobe, which were treated with radiosurgery. Eight months later (18 months from initial surgery), the patient underwent thoracic laminectomy for a large leptomeningeal metastasis at T6 and T8. Conclusion: The present case of MPE with anaplastic features is the fourth case on record in the medical literature. PMID- 30294496 TI - Aneurysm of lenticulostriate artery in a patient presenting with hemorrhage in the caudate nucleus and lateral ventricle-delayed appearance and spontaneous resolution. AB - Background: An aneurysm of distal lenticulostriate artery is very rare. The natural course and management of this rare aneurysm are not clear. Case Description: An 81-year-old woman developed consciousness disturbance. Computed tomography revealed hemorrhage in the right caudate nucleus and lateral ventricles. Three-dimensional computed tomographic angiography demonstrated only an aneurysm at the basilar artery. On angiography, on the sixth day, an aneurysm at the right lenticulostriate artery was demonstrated. Then, the aneurysm disappeared on three-dimensional computed tomographic angiography on the 15th day. Subsequent radiological examinations revealed no vascular anomaly in the right lenticulostriate artery. Conclusion: An aneurysm at this location can show dynamic changes based on radiological findings. Close radiological observation is necessary. PMID- 30294497 TI - An unusual presentation of dystonia and chorea from intraventricular pneumocephalus. AB - Background: Pneumocephalus is a common finding following intracranial procedures, typically asymptomatic and resolves within several days. However, in some cases, pneumocephalus presents with headache, encephalopathy, or symptoms of elevated intracranial pressure. Here, we present a case of iatrogenic tension pneumocephalus following endoscopic sinus surgery, presenting as abnormal involuntary movements resembling a movement disorder with choreiform movements. Case Description: A 67-year-old previously healthy male presented with new onset chorea and dystonia associated with headache, encephalopathy, and postural instability 4 days after undergoing endoscopic sinus surgery for chronic sinusitis and nasal polyps. Computed tomography showed prominent intraventricular pneumocephalus causing enlargement of the anterior horns of both lateral ventricles with lateral displacement of the basal ganglia nuclei and a bony defect in the skull base. Neurosurgical correction of the cranial defect provided complete symptomatic resolution. Pneumocephalus as a result of an iatrogenic injury of the skull base manifesting as an acute movement disorder is a rare complication of a nasal sinus procedure. We speculate that compression of the caudate nucleus and striatum resulted in decreased pallidothalamic inhibition and thalamocortical disinhibition leading to the development of a hyperkinetic movement disorder. Conclusion: This unusual presentation of a common procedure illustrates a neurological emergency that requires prompt recognition and timely correction. PMID- 30294498 TI - A rare cause of thoracic cord compression. AB - Background: The posterior longitudinal ligament (PLL) extends from the foramen magnum to the sacrum. In some cases, it becomes calcified/ossified; the term for this is ossification of the PLL (OPLL). Case Description: A 50-year-old female presented with acute sphincter dysfunction and paraparesis attributed to T2-T4 OPLL. The patient underwent a C7-T5 laminectomy to decompress the spinal cord. After 1 postoperative week, and certainly by 6 months postoperatively, the patient's motor and sensory deficits showed improvement. Conclusion: Surgery for thoracic OPLL includes laminoplasty, laminectomy with/without fusion, anterior decompression through a posterior approach (transpedicular, costotransversectomy), and circumferential decompression (e.g. combined anterior/posterior approaches). In cases like the one presented, patients who originally present with acute paraparesis/sphincter dysfunction may demonstrate postoperative improvement. PMID- 30294499 TI - Cerebrospinal fluid drainage and blood pressure elevation to treat acute spinal cord infarct. AB - Background: Current management of acute spinal cord infarction (SCI) is limited. Lumbar cerebrospinal fluid drainage (CSFD) with blood pressure augmentation is utilized in the thoracic/thoracoabdominal aortic repair and thoracic endovascular aortic repair (TEVAR) populations to increase spinal perfusion pressure. Case description: We identified 3 patients who sustained acute SCI and underwent CSFD and maintenance of elevated mean arterial pressure (MAP) within 24 hours of injury. The first patient exhibited delayed-onset ischemia after a TEVAR. The second patient presented with an acute type B aortic intramural hematoma. The third patient developed spinal cord ischemia following bronchial artery embolization. There was significant improvement in the motor examination (e.g., ASIA impairment scale grade B or C) to grade D utilizing both blood pressure augmentation and CSFD. Conclusions: Lumbar CSFD with MAP elevation benefited 3 patients with acute SCI of varying etiologies. PMID- 30294500 TI - Using Heatmaps to Identify Opportunities for Optimization of Test Utilization and Care Delivery. AB - Background: When a provider orders a test in a pattern that is substantially different than their peers, it may indicate confusion in the test name or inappropriate use of the test, which can be elucidated by initiating dialog between clinicians and the laboratory. However, the analysis of ordering patterns can be challenging. We propose a utilization index (UI) as a means to quantify utilization patterns for individual providers and demonstrate the use of heatmaps to identify opportunities for improvement. Materials and Methods: Laboratory test orders by all providers were extracted from the laboratory information system. Providers were grouped into cohorts based on the specialty and patient population. A UI was calculated for each provider's use of each test using the following formula: (UI = [provider volume of specific test/provider volume of all tests]/[cohort volume of specific test/cohort volume of all tests]). A heatmap was generated to compare each provider to their cohort. Results: This method identified several hot spots and was helpful in reducing confusion and overutilization. Conclusion: The UI is a useful measure of test ordering behavior, and heatmaps provide a clear visual illustration of the utilization indices. This information can be used to identify areas for improvement and initiate meaningful dialog with providers, which will ultimately bring improvement and reduction in costs. Our method is simple and uses resources that are widely available, making this method effective convenient for many other laboratories. PMID- 30294502 TI - Innovation in Transplantation: The Digital Era. AB - The international symposium entitled "Innovation in Transplantation: The Digital Era" took place on June 7 and 8, 2018 in Verona, Italy. This meeting was borne out of the productive collaboration between the Universities and Hospital Trusts of Verona and Padua in Italy, in the context of a vast regional project called Research and innovation project within the Health Technology Assessment. The project aimed to create an innovative digital platform for teleconsultation and delivering diagnostic second opinions in the field of organ transplantation within the Veneto region. This conference brought together pathologists, health informatics leaders, clinicians, researchers, vendors, and health-care planners from all around the globe. The symposium was conceived to promote the exchange of knowledge and kindle fertile discussion among the 130 attendees from 15 different countries. This article conveys the highlights of this symposium. PMID- 30294501 TI - Diagnostic Performance of Deep Learning Algorithms Applied to Three Common Diagnoses in Dermatopathology. AB - Background: Artificial intelligence is advancing at an accelerated pace into clinical applications, providing opportunities for increased efficiency, improved accuracy, and cost savings through computer-aided diagnostics. Dermatopathology, with emphasis on pattern recognition, offers a unique opportunity for testing deep learning algorithms. Aims: This study aims to determine the accuracy of deep learning algorithms to diagnose three common dermatopathology diagnoses. Methods: Whole slide images (WSI) of previously diagnosed nodular basal cell carcinomas (BCCs), dermal nevi, and seborrheic keratoses were annotated for areas of distinct morphology. Unannotated WSIs, consisting of five distractor diagnoses of common neoplastic and inflammatory diagnoses, were included in each training set. A proprietary fully convolutional neural network was developed to train algorithms to classify test images as positive or negative relative to ground truth diagnosis. Results: Artificial intelligence system accurately classified 123/124 (99.45%) BCCs (nodular), 113/114 (99.4%) dermal nevi, and 123/123 (100%) seborrheic keratoses. Conclusions: Artificial intelligence using deep learning algorithms is a potential adjunct to diagnosis and may result in improved workflow efficiencies for dermatopathologists and laboratories. PMID- 30294503 TI - Ring Expansion of Bicyclic Methyleneaziridines via Concerted, Near-Barrierless [2,3]-Stevens Rearrangements of Aziridinium Ylides. AB - The synthesis of densely functionalized azetidinesin a highly stereocontrolled manner is challenging, but interest in the bioactivities of these small heterocycles has stimulated methods for their preparation. We recently reported a one-carbon ring expansion of bicyclic methylene aziridines under dirhodium catalysis capable of delivering enantioenriched azetidines. This work explores this ring expansion using computational and experimental studies. DFT computations indicate that the reaction proceeds through formation of an aziridinium ylide, which is precisely poised for concerted, asynchronous ring opening/closing to deliver the azetidines in a [2,3]-Stevens-type rearrangement. The concerted nature of this rearrangement is responsible for the stereospecificity of the reaction, where axial chirality from the initial allene substrate is transferred to the azetidine product with complete fidelity. The computed mechanistic pathway highlights the key roles of the olefin and the rigid structure of the methylene aziridine in differentiating our observed ring expansion from competing cheletropic elimination pathways noted with ylides derived from typical aziridines. PMID- 30294504 TI - Development of de Novo Copper Nitrite Reductases: Where We Are and Where We Need To Go. AB - The development of redox-active metalloprotein catalysts is a challenging objective of de novo protein design. Within this Perspective we detail our efforts to create a redox-active Cu nitrite reductase (NiR) by incorporating Cu into the hydrophobic interior of well-defined three-stranded coiled coils (3SCCs). The scaffold contains three histidine residues that provide a layer of three nitrogen donors that mimic the type 2 catalytic site of NiR. We have found that this strategy successfully produces an active and stable CuNiR model that functions for over 1000 turnovers. Spectroscopic evidence indicates that the Cu(I) site has a lower coordination number in comparison to the enzyme, whereas the Cu(II) geometry may more faithfully reproduce the NiR type 2 center. Mutations at the helical interface successfully produce a hydrogen bond between an interfacial Glu residue and the Culigating His residue, which allows for the tuning of the redox potential over a 100 mV range. We successfully created constructs with as much as a 120-fold improvement from the original design by modifying the steric bulk above or below the Cu binding site. These systems are now the most active water-soluble and stable artificial NiR catalysts yet produced. Several avenues for improving the catalytic efficiency of later designs are detailed within this Perspective, including adjustment of their resting oxidation state, the use of asymmetric scaffolds to allow for single amino acid mutation within the second coordination sphere, and the design of hydrogen bonding networks to tune residue orientation and electronics. Through these studies the TRI-H system has given insight into the difficulties that arise in creating a de novo redox active enzyme. Work to improve upon this model will provide strategies by which redox-active de novo enzymes may be tuned and detail how native enzymes accomplish catalytic efficiencies through proton gated redox catalysis. PMID- 30294505 TI - Impact of Infant-Polysomnography Studies on Discharge Management and Outcomes: A 5 Year Experience from a Tertiary Care Unit. AB - Objective: To evaluate the impact of infant-polysomnography studies performed in the NICU on management and outcomes. Study design: Retrospective study to collect demographics and data on infant-polysomnography studies between Jan 2010 to Dec 2014. Results: 110 premature neonates had polysomnography study performed at 36.9 +/- 2.5 weeks post menstrual age. Almost all the studies were read as abnormal and 95% of the studied infants were discharged home on a cardiorespiratory monitor. 20% of the subjects had apnea >20 s, 18% had apnea of 15-20 s and 50% of infants had apnea of 10-15 s. 24.5% infants were discharged home on caffeine, 28% on metoclopramide and 24% on antacids. There were 11 readmissions for apparent life threatening events with no until 6 month-corrected age. There was no association between polysomnography results and readmission. There was a decline in polysomnography studies performed each year. Conclusion: Cardiorespiratory monitoring, medications and polysomnography studies do not predict outcomes. PMID- 30294506 TI - Microbial interactions with the intestinal epithelium and beyond: Focusing on immune cell maturation and homeostasis. AB - Microbial metabolites influence the function of epithelial, endothelial and immune cells in the intestinal mucosa. Microbial metabolites like SCFAs and B complex vitamins direct macrophage polarization whereas microbial derived biogenic amines modulate intestinal epithelium and immune response. Aberrant bacterial lipopolysaccharide-mediated signaling may be involved in the pathogenesis of chronic intestinal inflammation and colorectal carcinogenesis. Our perception of human microbes has changed from that of opportunistic pathogens to active participants maintaining intestinal and whole body homeostasis. This review attempts to explain the dynamic and enriched interactions between the intestinal epithelial mucosa and commensal bacteria in homeostasis maintenance. PMID- 30294507 TI - Can secondary contact following range expansion be distinguished from barriers to gene flow? AB - Secondary contact is the reestablishment of gene flow between sister populations that have diverged. For instance, at the end of the Quaternary glaciations in Europe, secondary contact occurred during the northward expansion of the populations which had found refugia in the southern peninsulas. With the advent of multi-locus markers, secondary contact can be investigated using various molecular signatures including gradients of allele frequency, admixture clines, and local increase of genetic differentiation. We use coalescent simulations to investigate if molecular data provide enough information to distinguish between secondary contact following range expansion and an alternative evolutionary scenario consisting of a barrier to gene flow in an isolation-by-distance model. We find that an excess of linkage disequilibrium and of genetic diversity at the suture zone is a unique signature of secondary contact. We also find that the directionality index psi, which was proposed to study range expansion, is informative to distinguish between the two hypotheses. However, although evidence for secondary contact is usually conveyed by statistics related to admixture coefficients, we find that they can be confounded by isolation-by-distance. We recommend to account for the spatial repartition of individuals when investigating secondary contact in order to better reflect the complex spatio temporal evolution of populations and species. PMID- 30294508 TI - Transkingdom network reveals bacterial players associated with cervical cancer gene expression program. AB - Cervical cancer is the fourth most common cancer in women worldwide with human papillomavirus (HPV) being the main cause the disease. Chromosomal amplifications have been identified as a source of upregulation for cervical cancer driver genes but cannot fully explain increased expression of immune genes in invasive carcinoma. Insight into additional factors that may tip the balance from immune tolerance of HPV to the elimination of the virus may lead to better diagnosis markers. We investigated whether microbiota affect molecular pathways in cervical carcinogenesis by performing microbiome analysis via sequencing 16S rRNA in tumor biopsies from 121 patients. While we detected a large number of intra-tumor taxa (289 operational taxonomic units (OTUs)), we focused on the 38 most abundantly represented microbes. To search for microbes and host genes potentially involved in the interaction, we reconstructed a transkingdom network by integrating a previously discovered cervical cancer gene expression network with our bacterial co-abundance network and employed bipartite betweenness centrality. The top ranked microbes were represented by the families Bacillaceae, Halobacteriaceae, and Prevotellaceae. While we could not define the first two families to the species level, Prevotellaceae was assigned to Prevotella bivia. By co-culturing a cervical cancer cell line with P. bivia, we confirmed that three out of the ten top predicted genes in the transkingdom network (lysosomal associated membrane protein 3 (LAMP3), STAT1, TAP1), all regulators of immunological pathways, were upregulated by this microorganism. Therefore, we propose that intra-tumor microbiota may contribute to cervical carcinogenesis through the induction of immune response drivers, including the well-known cancer gene LAMP3. PMID- 30294509 TI - Geopolitical species revisited: genomic and morphological data indicate that the roundtail chub Gila robusta species complex (Teleostei, Cyprinidae) is a single species. AB - The Gila robusta species complex in the Lower Colorado River Basin has a complicated taxonomic history. Recent authors have separated this group into three nominal taxa, G. robusta, G. intermedia, and G. nigra, however aside from location, no reliable method of distinguishing individuals of these species currently exists. To assess relationships within this group, we examined morphology of type specimens and fresh material, and used RADseq methods to assess phylogenetic relationship among these nominal species. Maximum likelihood and Bayesian inference tree building methods reveal high concordance between tree topologies based on the mitochondrial and nuclear datasets. Coalescent SNAPP analysis resolved a similar tree topology. Neither morphological nor molecular data reveal diagnostic differences between these species as currently defined. As such, G. intermedia and G. nigra should be considered synonyms of the senior G. robusta. We hypothesize that climate driven wet and dry cycles have led to periodic isolation of population subunits and subsequent local divergence followed by reestablished connectivity and mixing. Management plans should therefore focus on retaining genetic variability and viability of geographic populations to preserve adaptability to changing climate conditions. PMID- 30294510 TI - An adaptive scale Gaussian filter to explain White's illusion from the viewpoint of lightness assimilation for a large range of variation in spatial frequency of the grating and aspect ratio of the targets. AB - The variation between the actual and perceived lightness of a stimulus has strong dependency on its background, a phenomena commonly known as lightness induction in the literature of visual neuroscience and psychology. For instance, a gray patch may perceptually appear to be darker in a background while it looks brighter when the background is reversed. In the literature it is further reported that such variation can take place in two possible ways. In case of stimulus like the Simultaneous Brightness Contrast (SBC), the apparent lightness changes in the direction opposite to that of the background lightness, a phenomenon often referred to as lightness contrast, while in the others like neon colour spreading or checkerboard illusion it occurs opposite to that, and known as lightness assimilation. The White's illusion is a typical one which according to many, does not completely conform to any of these two processes. This paper presents the result of quantification of the perceptual strength of the White's illusion as a function of the width of the background square grating as well as the length of the gray patch. A linear filter model is further proposed to simulate the possible neurophysiological phenomena responsible for this particular visual experience. The model assumes that for the White's illusion, where the edges are strong and quite a few, i.e., the spectrum is rich in high frequency components, the inhibitory surround in the classical Difference-of Gaussians (DoG) filter gets suppressed, and the filter essentially reduces to an adaptive scale Gaussian kernel that brings about lightness assimilation. The linear filter model with a Gaussian kernel is used to simulate the White's illusion phenomena with wide variation of spatial frequency of the background grating as well as the length of the gray patch. The appropriateness of the model is presented through simulation results, which are highly tuned to the present as well as earlier psychometric results. PMID- 30294511 TI - De novo transcriptome sequencing and analysis of genes related to salt stress response in Glehnia littoralis. AB - Soil salinity is one of the major environmental stresses affecting plant growth, development, and reproduction. Salt stress also affects the accumulation of some secondary metabolites in plants. Glehnia littoralis is an endangered medicinal halophyte that grows in coastal habitats. Peeled and dried Glehnia littoralis roots, named Radix Glehniae, have been used traditionally as a Chinese herbal medicine. Although Glehnia littoralis has great ecological and commercial value, salt-related mechanisms in Glehnia littoralis remain largely unknown. In this study, we analysed the transcriptome of Glehnia littoralis in response to salt stress by RNA-sequencing to identify potential salt tolerance gene networks. After de novo assembly, we obtained 105,875 unigenes, of which 75,559 were annotated in public databases. We identified 10,335 differentially expressed genes (DEGs; false discovery rate <0.05 and |log2 fold-change| >= 1) between NaCl treatment (GL2) and control (GL1), with 5,018 upregulated and 5,317 downregulated DEGs. To further this investigation, we performed Gene Ontology (GO) analysis and the Kyoto Encyclopaedia of Genes and Genomes (KEGG) pathway analysis. DEGs involved in secondary metabolite biosynthetic pathways, plant signal transduction pathways, and transcription factors in response to salt stress were analysed. In addition, we tested the gene expression of 15 unigenes by quantitative real-time PCR (qRT-PCR) to confirm the RNA-sequencing results. Our findings represent a large-scale assessment of the Glehnia littoralis gene resource, and provide useful information for exploring its molecular mechanisms of salt tolerance. Moreover, genes enriched in metabolic pathways could be used to investigate potential biosynthetic pathways of active compounds by Glehnia littoralis. PMID- 30294513 TI - Periwinkle climbing response to water- and airbone predator chemical cues may depend on home-marsh geography. AB - The salt marsh periwinkle, Littorina irrorata, exhibits a spatial refuge from predation by climbing the stems of Spartina alterniflora in order to avoid benthic predators. Salt marsh periwinkles have a broad geographic distribution, and for many species, responses to predators also varies with biogeography. This study sought to determine if the geographical location of the home marsh influenced the response of periwinkles (climbing height) to blue crab predator cues both via air and water. Snails from Louisiana (LA) climbed higher in general than those from North Carolina (NC), regardless of chemical cue. However, LA snails climbed 11 cm higher in the presence of waterborne predators than control snails with no cue, while NC snails only climbed five cm higher in the same comparisons. Airborne chemical cue tended to have snails climbing at intermediate heights. These responses were significantly enhanced when both populations of snails were housed together. Periwinkle response to predator cues was stronger in LA than NC, and so it is possible that the behavioral response of these snails to predators varies with biogeography of the home marsh. Also interestingly, the results of this study also suggest that cue delivery is probably occurring via mechanisms other than water, and potentially via airborne cues. Therefore, salt marsh periwinkles likely respond to numerous cues that initiate behavioral responses, including airborne cues, and these responses may vary by home-marsh geography.

AB - Both age and intensive exercise are generally considered critical risk factors for osteoarthritis. In this work, we intend to establish zebrafish models to assess the role of these two factors on cartilage homeostasis. We designed a swimming device for zebrafish intensive exercise. The body measurements, bone mineral density (BMD) and the histology of spinal cartilages of 4- and 12-month old zebrafish, as well the 12-month-old zebrafish before and after a 2-week exercise were compared. Our results indicate that both age and exercise affect the body length and body weight, and the micro-computed tomography reveals that both age and exercise affect the spinal BMD. However, quantitative analysis of immunohistochemistry and histochemistry indicate that short-term intensive exercise does not affect the extracellular matrix (ECM) of spinal cartilage. On the other hand, the cartilage ECM significantly grew from 4 to 12 months of age with an increase in total chondrocytes. dUTP nick end labeling staining shows that the percentages of apoptotic cells significantly increase as the zebrafish grows, whereas the BrdU labeling shows that proliferative cells dramatically decrease from 4 to 12 months of age. A 30-day chase of BrdU labeling shows some retention of labeling in cells in 4-month-old spinal cartilage but not in cartilage from 12-month-old zebrafish. Taken together, our results suggest that zebrafish chondrocytes are actively turned over, and indicate that aging is a critical factor that alters cartilage homeostasis. Zebrafish vertebral cartilage may serve as a good model to study the maturation and homeostasis of articular cartilage.

AB - Background: Macroinvertebrates in aquatic ecosystems are repeatedly exposed to pesticides during their life cycle. Effects of consecutive exposure during different life stages and possible synergistic effects are not addressed in the standardized hazard assessment. The present study investigated two environmentally relevant exposure scenarios in batch (microcosm) and artificial indoor stream (mesocosm) experiments using the larvae of the mayfly Rhithrogena semicolorata (grazer) and natural aufwuchs. Grazers were analysed regarding growth, physiological condition, and drift behaviour, while the aufwuchs was analysed in terms of biomass using the particulate organic carbon as well as the chlorophyll a content. The aim was to reveal direct and indirect effects of an herbicide exposure during autumn on juvenile grazers and an insecticide exposure during spring on semi-juvenile grazers. Results: Direct and indirect effects were found in both exposure scenarios at environmentally relevant concentrations. In the herbicide exposure scenario with terbutryn, clear direct effects on the aufwuchs community with a LOEC of 0.38 ug L-1 were found. Effect levels of grazers due to indirect effects were equal, with the overnight drift being the most sensitive grazer endpoint. In the insecticide exposure scenario, clear lethal and sub lethal effects of lambda-cyhalothrin were evident. Derived LC50 values for the artificial indoor stream and batch experiment were 2.42 ug g-1 OC (69 days) and 1.2 ug g-1 OC (28 days), respectively. Sub lethal effects in terms of increased drift as well-reduced growth and triglyceride levels were found at concentrations of 1.4 and 0.09 ug g-1 OC (LOECs). These results were confirmed by the batch experiment, which revealed effect values in the similar range. Finally, a clear indirect effect of the insecticide on the aufwuchs was evident in the batch experiment with an LOEC at 0.9 ug g-1 OC. Conclusion: Toxicity Exposure Ratios calculated with the derived effect values indicate a risk for the investigated grazer by both pesticides. Moreover, observed indirect effects during the herbicide exposure seem to be able to affect the grazers during a second exposure with an insecticide, due to reduced physiological conditions. We suggest further research with time-shifted exposure scenarios to gain a better understanding of the complex interactions of pesticides with the life cycle and the food webs of macroinvertebrates. PMID- 30294515 TI - Modelling effects of time-variable exposure to the pyrethroid beta-cyfluthrin on rainbow trout early life stages. AB - Background: Available literature and regulatory studies show that the severity of effects of beta-cyfluthrin (a synthetic pyrethroid) on fish is influenced by the magnitude and duration of exposure. To investigate how the exposure pattern to beta-cyfluthrin (constant vs peak) may influence the response of the fish, we used a mechanistic effect model to predict the survival and growth of the rainbow trout over its early life stages (i.e. egg, alevin and swim-up fry). We parameterized a toxicokinetic-toxicodynamic (TKTD) module in combination with a dynamic energy budget model enabling us to describe uptake and elimination, as well as to predict the threshold concentration for survival and sublethal effects (feeding behaviour and growth). This effect model was calibrated using data from an early life stage experiment where trout was exposed to a constant concentration of cyfluthrin. The model was validated by comparing model predictions to independent data from a pulsed-exposure study with early life stages of rainbow trout. Results: The co-occurrence of effects on behaviour and growth raised the possibility that these were interrelated, i.e. impairment of feeding behaviour may have led to reduced food intake and slower growth. We, therefore, included 'effect on feeding' as mode of action in the TKTD module. At higher concentrations, the constant exposure led to death. The model was able to adequately capture this effect pattern in the calibration. The model was able to adequately predict the response of fish eggs, alevins and swim-up fry, from both the qualitative (response pattern) and quantitative points of view. Conclusions: Since the model was successfully validated, it can be used to predict survival and growth of early life stages under various realistic time-variable exposure profiles (e.g. profiles from FOCUS surface water modelling) of beta-cyfluthrin. PMID- 30294516 TI - Systematic miRNome profiling reveals differential microRNAs in transgenic maize metabolism. AB - Background: While some genetically modified organisms (GMOs) are created to produce new double-stranded RNA molecules (dsRNA), in others, such molecules may occur as an unintended effect of the genetic engineering process. Furthermore, GMOs might produce naturally occurring dsRNA molecules in higher or lower quantities than its non-transgenic counterpart. This study is the first to use high-throughput technology to characterize the miRNome of commercialized GM maize events and to investigate potential alterations in miRNA regulatory networks. Results: Thirteen different conserved miRNAs were found to be dys-regulated in GM samples. The insecticide Bt GM variety had the most distinct miRNome. These miRNAs target a range of endogenous transcripts, such as transcription factors and nucleic acid binding domains, which play key molecular functions in basic genetic regulation. In addition, we have identified 20 potential novel miRNAs with target transcripts involved in lipid metabolism in maize. isomiRs were also found in 96 conserved miRNAs sequences, as well as potential transgenic miRNA sequences, which both can be a source of potential off-target effects in the plant genome. We have also provided information on technical limitations and when to carry on additional in vivo experimental testing. Conclusions: These findings do not reveal hazards per se but show that robust and reproducible miRNA profiling technique can strengthen the assessment of risk by detecting any new intended and unintended dsRNA molecules, regardless of the outcome, at any stage of GMO development.

The first Data Science initiative from the US National Institutes of Health was entitled "Big Data to Knowledge (BD2K)." The main emphasis of the more than $200M allocated to that program has been on "Big Data;" the "Knowledge" component has largely been the implicit assumption that the work will lead to new biomedical knowledge. However, there is long-standing and highly productive work in computational knowledge representation and reasoning, and computational processing of knowledge has a role in the world of Data Science. Knowledge-based biomedical Data Science involves the design and implementation of computer systems that act as if they knew about biomedicine. There are many ways in which a computational approach might act as if it knew something: for example, it might be able to answer a natural language question about a biomedical topic, or pass an exam; it might be able to use existing biomedical knowledge to rank or evaluate hypotheses; it might explain or interpret data in light of prior knowledge, either in a Bayesian or other sort of framework. These are all examples of automated reasoning that act on computational representations of knowledge. After a brief survey of existing approaches to knowledge-based data science, this position paper argues that such research is ripe for expansion, and expanded application. PMID- 30294519 TI - SCIT with a high-dose house dust mite allergoid is well tolerated: safety data from pooled clinical trials and more than 10 years of daily practice analyzed in different subgroups. AB - Background: Efficacy of house dust mite (HDM) allergen immunotherapy (AIT) in allergic rhinitis and controlled allergic asthma has been documented in controlled trials with adults and children. However, tolerability comparing clinical development and post marketing data, particularly in different subgroups, is missing. Methods: We performed an analysis of pooled safety data for subcutaneous AIT (SCIT) with a high-dose house dust mite allergoid from 6 randomized, controlled trials (RCT) in HDM allergic respiratory disease (ARD) and of post marketing safety data from more than 10 years including different subgroups (age, gender, asthma status). Results: In all, 500 patients with ARD were treated in RCTs: 279 received the marketed dose of 1800 protein nitrogen units (PNU) high-dose HDM allergoid AIT (214 double-blind placebo controlled [HDM DBPC], 65 children/adolescents usual care controlled [HDM-RCT(UC)]), and 221 placebo (PL). 38.8% adverse events (AEs) were observed with 1800 PNU in HDM-DBPC (31.2% PL, 35.5% HDM-ALL [1800 PNU]); the difference was primarily because of local reactions; there was no difference in systemic reactions (10.9% PL, 11.2% HDM-DBPC, 11.2% HDM-ALL); one out of 279 high-dose HDM allergoid-treated patients had a serious adverse event (SAE).Children (n = 39)/adolescents (n = 26) had fewer related AEs and local reactions compared to adults; systemic reactions: children 12.8%, adults 11.2% adolescents 7.7%. Females had slightly more AEs. Treatment was well tolerated in asthmatic patients (n = 267; GINA I n = 32, II n = 104, III n = 17, 114 no classification).In more than 10 years more than 100,000 patients were treated with high-dose HDM allergoid (1800 PNU) under daily practice conditions. Adverse drug reactions (ADRs) were reported in 0.5% of patients. 94.6% of these ADRs were expected. Conclusion: SCIT with the marketed dose of high-dose HDM allergoid was well tolerated in clinical development and in daily practice. There was no increased risk for the investigated patient subgroups. Tolerability was comparable to HDM sublingual immunotherapy (SLIT) tablets. PMID- 30294518 TI - Strategies for the elimination of hepatitis C virus infection as a public health threat in the United States. AB - Purpose of Review: Direct-acting antiviral regimens for chronic hepatitis C virus (HCV) became available in 2014, and these highly curative therapies have the potential to reduce HCV-associated morbidity and mortality, decrease transmission, and eliminate HCV infection as a public health problem. This review summarizes the recommendations by the National Academies of Sciences, Engineering, and Medicine for a US strategy for HCV elimination. Recent Findings: To achieve proposed targets of reducing HCV incidence by 90% and decreasing HCV related mortality by 60% by 2030, there is a critical need to improve HCV diagnosis and linkage to care; reduce HCV-related disease by antiviral treatment scale-up; reduce HCV incidence; and strengthen HCV surveillance to determine achievement of HCV elimination targets over time. Summary: While HCV elimination is feasible, success of this national effort will require ongoing collaboration and critical resource investment by key stakeholders, including medical and public health communities, legislators, community organizers, and patient advocates. PMID- 30294521 TI - Hybrid control combined with a voluntary biosignal to control a prosthetic hand. AB - In this research, the combination of fuzzy/PD and EMG signals, as direct command control, is proposed. Although fuzzy/PD strategy was used to control force position of the artificial hand, the combination of that with EMG signaling to voluntary direct command control is a novel method. In this paper, the EMG signal and its role in effective communication between a DC motor with a voltage trigger and neurofeedback are initially explained. Moreover, by introducing a filtration method, EMG pulses are obtained as stepping pulses with a signal-specific height of a voltage between 0 and 6 V, according to EMG domain voltage, with a time interval adapted from the EMG stimulus pulses. Two data points from each channel of EMG were extracted. The domain of the voltage of the EMG signal is impacted on the output of the fuzzy logic unit, and also the time amount between each stimulus of the EMG signal is the input of the PD controller. By this method, a user can influence grip position and grasping force of his/her prosthesis. PMID- 30294522 TI - Intelligence and global health: assessing the role of open source and social media intelligence analysis in infectious disease outbreaks. AB - Purpose: Open Source Intelligence (OSINT) and Signals Intelligence (SIGINT) from the clandestine intelligence sector are being increasingly employed in infectious disease outbreaks. The purpose of this article is to explore how such tools might be employed in the detection, reporting, and control of outbreaks designated as a 'threat' by the global community. It is also intended to analyse previous use of such tools during the Ebola and SARS epidemics and to discuss key questions regarding the ethics and legality of initiatives that further blur the military and humanitarian spaces. Methods: We undertake qualitative analysis of current discussions on OSINT and SIGINT and their intersection with global health. We also review current literature and describe the debates. We built on quantitative and qualitative research done into current health collection capabilities. Results: This article presents an argument for the use of OSINT in the detection of infectious disease outbreaks and how this might occur. Conclusion: We conclude that there is a place for OSINT and SIGINT in the detection and reporting of outbreaks. However, such tools are not sufficient on their own and must be corroborated for the intelligence to be relevant and actionable. Finally, we conclude that further discussion on key ethical issues needs to take place before such research can continue. In particular, this involves questions of jurisdiction, data ownership, and ethical considerations. PMID- 30294520 TI - Non-celiac gluten/wheat sensitivity (NCGS)-a currently undefined disorder without validated diagnostic criteria and of unknown prevalence: Position statement of the task force on food allergy of the German Society of Allergology and Clinical Immunology (DGAKI). AB - Within the last decade, non-celiac gluten/wheat sensitivity (NCGS) has been increasingly discussed not only in the media but also among medical specialties. The existence and the possible triggers of NCGS are controversial. Three international expert meetings which proposed recommendations for NCGS were not independently organized and only partially transparent regarding potential conflicts of interest of the participants. The present position statement reflects the following aspects about NCGS from an allergist's and nutritionist's point of view: (A) Validated diagnostic criteria and/or reliable biomarkers are still required. Currently, this condition is frequently self-diagnosed, of unknown prevalence and non-validated etiology. (B) Gluten has not been reliably identified as an elicitor of NCGS because of high nocebo and placebo effects. Double-blind, placebo-controlled provocation tests are of limited value for the diagnosis of NCGS and should be performed in a modified manner (changed relation of placebo and active substance). (C) Several confounders hamper the assessment of subjective symptoms during gluten-reduced or gluten-free diets. Depending on the selection of food items, e.g., an increased vegetable intake with soluble fibers, diets may induce physiological digestive effects and can modify gastrointestinal transit times independent from the avoidance of gluten. (D) A gluten-free diet is mandatory in celiac disease based on scientific evidence. However, a medically unjustified avoidance of gluten may bear potential disadvantages and risks. (E) Due to a lack of diagnostic criteria, a thorough differential diagnostic work-up is recommended when NCGS is suspected. This includes a careful patient history together with a food-intake and symptom diary, if necessary an allergy diagnostic workup and a reliable exclusion of celiac disease. We recommend such a structured procedure since a medically proven diagnosis is required before considering the avoidance of gluten. PMID- 30294523 TI - Using Mindfulness for the Treatment of Insomnia. AB - Purpose of review: The goal of this review is to provide an update on the use of mindfulness meditation for the treatment of insomnia, including conceptual models and empirical evidence from randomized controlled trials. Recent findings: A metacognitive model of insomnia has been proposed as a conceptual model to explain the application of mindfulness principles for reducing insomnia-related arousal. Furthermore, the evidence base for mindfulness-based therapies has grown with the results of several randomized controlled trials published in the past three years. Treatment effects appear to be strongest on self-report measures compared to objective measures of sleep. Summary: Treatment programs featuring mindfulness meditation appear to be viable treatment options for people with insomnia. Further research is needed to determine who is likely to benefit from mindfulness-based therapies and how these interventions work. Additionally, further work is needed to resolve issues related to the delivery and implementation of mindfulness-based therapies. PMID- 30294524 TI - Biologics for the treatment of noninfectious uveitis. PMID- 30294525 TI - Recommendation of using systemic anti-tumor necrosis factor-alpha for the treatment of noninfectious uveitis in Taiwan. AB - Noninfectious uveitis is a sight-threatening disease with an autoimmune or autoinflammatory basis. Systemic treatment is required if intraocular inflammation threatens a patient's vision or cannot be controlled locally and when it is associated with systemic rheumatic diseases. Corticosteroids and immunomodulatory chemotherapy are the conventional initial treatments. However, the various side effects of these therapies increase the burden on patients, not only physically but also mentally. Moreover, uncontrolled inflammation and poor visual outcomes have sometimes been recorded despite the combination of these medications or their high dosage. Antitumor necrosis factor-alpha (anti-TNF alpha) and other biologic agents have been widely used to treat rheumatic diseases for >15 years. Randomized controlled clinical trials have demonstrated that anti-TNF-alpha can reduce and delay episodes of intraocular inflammation not only in patients with active uveitis but also in corticosteroid-dependent patients with inactive uveitis. The Taiwan Food and Drug Administration approved the use of adalimumab, an anti-TNF-alpha agent, for treating nonanterior noninfectious uveitis (NANIU) in 2017. This report provides a recommendation and a proposed stepladder approach for using anti-TNF-alpha agents to treat NANIU in Taiwan. PMID- 30294527 TI - Dexamethasone implant (0.7 mg) in Indian patients with macular edema: Real-life scenario. AB - Context: Role of Ozurdex in macular edema due to various posterior segment pathologies. AIM: The aim of this study is to report outcome of Ozurdex implant in macular edema (ME) secondary to various posterior segment pathologies. SETTINGS AND DESIGN: This was a single-center, retrospective, interventional study. SUBJECTS AND METHODS: Patients of ME were treated with one or more Ozurdex implants (0.7 mg). Data collection included demographic details, best-corrected visual acuity (BCVA), central foveal thickness (CFT), duration of efficacy, and record of adverse events (if any) within 24 weeks. STATISTICAL ANALYSIS USED: Paired sample t-test, Stata data analysis, and statistical software, version 12.1, StataCorp, College Station, TX, USA, were used in the study. RESULTS: One hundred and sixteen eyes of 104 patients were studied which had a diagnosis of diabetic ME (n = 46), retinal vein occlusion (n = 40), and uveitis (n = 30). The average age of patients (mean +/- standard deviation) was 50.2 +/- 21.9 years. Baseline mean +/- SD (standard deviation) logMAR BCVA, CFT, and intraocular pressure (IOP) were 0.636 +/- 0.4, 527.8 +/- 210.1 MUm, and 15.3 +/- 3.8 mmHg, respectively. The reinjection interval was around 12-18 weeks. Ozurdex proved its efficacy in improving mean logMAR visual acuity and reduction of CFT from baseline till 12 weeks' follow-up period (0.414 +/- 0.5 and 301.5 +/- 278.5, respectively; P < 0.05), and after 12 weeks' follow-up, it started worsening (0.530 +/- 0.9 and 444.8 +/- 375.2, respectively; P > 0.05). The most common reported adverse event was significant rise of IOP (>5 mmHg), with a total of 12 cases followed by cataract 9 cases. CONCLUSION: Ozurdex implant leads to a significant improvement in BCVA and CFT values till 12 weeks, followed by a gradual decline for all the pathologies studied together. No new safety concerns were observed with the Ozurdex implant. The duration of efficacy was found to be <24 weeks. PMID- 30294528 TI - Photorefractive keratectomy for correcting residual refractive error following cataract surgery with premium intraocular lens implantation. AB - PURPOSE: The aim of this study is to evaluate the effectiveness and predictability of photorefractive keratectomy (PRK) for correcting residual refractive error following cataract surgery with premium intraocular lens (IOL) implantation. METHODS: We conducted a retrospective review of the medical records of patients who received PRK for correcting residual hyperopia, myopia, and/or astigmatism due to unsatisfied uncorrected distance visual acuity (UDVA) after cataract extraction with implantation of aspheric, diffractive multifocal, or toric IOL from September 2011 to December 2017. Pre-cataract surgery, pre- and post-PRK data including UDVA, best-corrected distance visual acuity, and refractive status were analyzed. RESULTS: A total of 18 consecutive eyes in 17 patients were included in this study. The UDVA after PRK improved 1 line or more in 10 eyes, remained unchanged in five eyes, and decreased in three eyes. The overall improvement in the logarithm of minimal angle of resolution (logMAR) UDVA after PRK was significant (P < 0.05). While dividing patients into subgroups based on IOL type, significant improvement in logMAR UDVA was found in patients with aspheric IOL or diffractive multifocal IOL implantation (P < 0.05). No significant improvement of UDVA was found in patients with toric IOL implantation. All eyes achieved +/- 1.00 D of the attempted spherical correction, demonstrating good predictability of PRK. CONCLUSIONS: PRK was a safe and effective procedure to correct residual refractive error following cataract extraction with premium IOL implantation. Although satisfactory for all patients, the outcome is better and more predictable in patients with aspheric and diffractive multifocal IOL implantation and is less satisfactory and unpredictable in patients with toric IOL implantation. PMID- 30294526 TI - Correction of presbyopia: An integrated update for the practical surgeon. AB - Presbyopia results from loss or insufficiency of the eye's accommodative ability, and clinically manifests as the inability to focus near objects on the retina. It is one of the most common causes of visual impairment worldwide especially in adults of productive or working age. Various means of compensating for the loss of accommodative ability have been devised from optical tools such as spectacles and contact lenses, to topical medications and to surgical procedures. A comprehensive search on journal articles about topical and surgical correction of presbyopia was undertaken. The various techniques for presbyopia correction, as enumerated in these articles, are discussed in this paper with the addition of our personal experience and perspective on the future of these techniques. PMID- 30294529 TI - Ultra-widefield angiography in the diagnosis and management of uveitis. AB - PURPOSE: The aim of this study is to evaluate the clinical use of ultra-widefield angiography (UWFA) in uveitis. MATERIALS AND METHODS: We showed the UWFA and traditional 55 degrees fluorescein angiography (FA) of four cases with Eales' disease, idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome, Behcet's disease, and idiopathic panuveitis in a tertiary medical center. Comparison of UWFA with traditional 55 degrees FA in the diagnosis and management of uveitis and review of the literature is also presented. RESULTS: Ultra widefield FA revealed far-peripheral vascular imaging. This information would not have been easily obtained from traditional FA. With more information of the peripheral retina, it may facilitate appropriate diagnosis and monitoring, and the management may be revised. CONCLUSION: University of Western Australia played an important role to confirm the diagnosis of uveitis and to determine the corresponding treatment. PMID- 30294530 TI - The rescue effect of adalimumab in the treatment of refractory pediatric panuveitis complicated with steroid-induced glaucoma. AB - We report the rescue effects of adalimumab (HUMIRA(r)) therapy in a case of refractory pediatric panuveitis complicated with steroid-induced glaucoma. A 13 year-old girl had suffered from blurred vision since January 2013. Bilateral idiopathic panuveitis with macular edema (ME) was diagnosed. She had previously been treated with systemic steroids, methotrexate, cyclosporine, and mycophenolate. All treatments had failed to suppress the ocular inflammation and ME persisted. Intravitreal dexamethasone implant injections were given to both eyes and ME subsided; however, complications with steroid-induced glaucoma and cataract occurred. ME also recurred following absorbance of the dexamethasone implant. After administration of subcutaneous adalimumab injections every 2 weeks, inflammatory activity was well controlled and ME subsided. Phacoemulsification and posterior intraocular lens implantation were performed in both eyes. Menorrhagia and anemia were noted 9 months after adalimumab treatment. Thereafter, adalimumab was reduced and her anemia improved. Her vision had remained 20/20 for 33 months. Refractory pediatric uveitis usually requires more aggressive treatment. Intraocular glucocorticoid releasing implant could be used to lessen the possible systemic side effects in children. Intravitreal dexamethasone implant was effective in treating the inflammatory ME but could be complicated with steroid glaucoma and cataract. Tumor necrosis factor-blocking agents have been used to treat chronic, refractory uveitis in adults as well as children. Adalimumab was a favorable biological agent in steroid-responding pediatric patient of refractory noninfectious uveitis but could be complicated with menorrhagia. Long-term follow-up and more cases are mandatory. PMID- 30294531 TI - Interferon-alpha2a treatment for refractory Behcet's disease. AB - We report a young male patient with Behcet's disease who suffered from sight threatening recurrences under treatment with azathioprine, cyclosporine, and prednisolone. His uveitis responded well to antitumor necrosis factor (TNF)-alpha (adalimumab) for 5 months subsequently. Severe uveitis recurred soon after discontinuation of anti-TNF alpha therapy and could not be controlled well with reinstitution of the anti-TNF alpha therapy. Interferon-alpha2a (IFN-alpha2a) was then given along with low-dose oral prednisone (10 mg/day), and the uveitis responded well to this therapy. We continued a maintenance dose with of IFN alpha2a three times/week for 2 years. Sight-threatening uveitis did not recur under IFN-alpha2a therapy, and the visual acuity improved from "counting fingers" to 20/100 in the right eye, while remaining stable with 20/20 vision in the left eye. The patient had flu-like symptoms, fever, and severe depression during IFN therapy, but an attempt to discontinue INF led to relapse within 1 month. This case report suggests that IFN-alpha2a could be an option for treatment in Behcet's uveitis. Further study is needed to clarify the efficacy and appropriate strategy for IFN-alpha2a therapy for Behcet's uveitis in Taiwan. PMID- 30294532 TI - Bilateral anterior uveitis after immunotherapy for malignant melanoma. AB - Immune checkpoint blockade therapy is relatively a new treatment for cancer which has shown promising results. However, immune-related side effects including uveitis have occasionally been reported during this therapy. Herein, we report the case of a 65-year-old male who suffered bilateral anterior uveitis after immune checkpoint blockade therapy with pembrolizumab and ipilimumab for malignant melanoma. His symptoms and signs improved after topical treatment with corticosteroids. Clinicians should be aware that uveitis can be an immune-related adverse event of immunotherapy. PMID- 30294533 TI - Acute syphilitic posterior placoid chorioretinopathy mimicking central serous chorioretinopathy: A case report. AB - A 51-year-old man had experienced declining visual acuity for 4 months. His best corrected visual acuity was 20/40 in both eyes. Ophthalmoscopic examination showed a yellowish placoid lesion over the macular area, and spectral-domain optical coherence tomography (SD-OCT) revealed subretinal fluid accumulation in the left eye, which resembled that seen with central serous chorioretinopathy (CSCR). Three days later, fluorescein angiography (FA) revealed fluorescein leakage, and indocyanine green angiography (ICGA) showed hypofluorescence over the lesion. Persistent ellipsoid zone loss as spontaneously resolved subretinal fluid was noted at the same time with SD-OCT. Laboratory examination disclosed positive rapid plasma reagin and Treponema pallidum particle agglutination tests (titer >1:1280), which confirmed the diagnosis of ocular syphilis. Acute syphilitic posterior placoid chorioretinopathy (ASPPC) could mimic CSCR with spontaneously resolved subretinal fluid observed in SD-OCT images. The acute loss of the ellipsoid zone, mismatched results from SD-OCT and FA, and picture of retinitis can also provide hints for differentiating the two diseases. PMID- 30294534 TI - Blastoschizomyces capitatus pneumonia in a patient with untreated chronic lymphocytic leukemia. AB - Several cases have been reported of B. capitatus infections in immunocompromised patients. Acute leukemia is the main predisposing factor. Chronic lymphocytic leukemia (CLL) is not usually associated with opportunistic infections. We report a case of pulmonary infection by B. capitatus in a patient with untreated chronic lymphocytic leukemia. Although the patient had a complete recovery, we believe that this report will alert clinicians to consider B. capitatus as possible cause of severe pneumonia in untreated CLL. PMID- 30294535 TI - Invasive rhinocerebral mucormycosis in a patient with liver cirrhosis leading to fatal massive stroke. AB - Immunocompromised status is associated with invasive fungal infections including mucormycosis. These infections are challenging to treat and associated with high overall mortality. Here we report a fatal case of invasive mucormycosis in a cirrhotic, diabetic patient. Despite the swift diagnosis and management; the fungal invasion of the right internal carotid artery lead to massive ischemic stroke. Timely diagnosis and management is crucial for management but it seems not always enough and new approaches for treatment must be sought. PMID- 30294536 TI - Dynamics of ecosystem services provided by subtropical forests in Southeast China during succession as measured by donor and receiver value. AB - The trends in the provision of ecosystem services during restoration and succession of subtropical forests and plantations were quantified, in terms of both receiver and donor values, based on a case study of a 3-step secondary succession series that included a 400-year-old subtropical forest and a 23-year history of growth on 3 subtropical forest plantations in Southeastern China. The 'People's Republic of China Forestry Standard: Forest Ecosystem Service Valuation Norms' was revised and applied to quantify the receiver values of ecosystem services, which were then compared with emergy-based, donor values of the services. The results revealed that the efficiencies of subtropical forests and plantations in providing ecosystem services were 2 orders of magnitude higher than similar services provided by the current China economic system, and these efficiencies kept increasing over the course of succession. As a result, we conclude that afforestation is an efficient way to accelerate both the ability and efficiency of subtropical forests to provide ecosystem services. The ability of different ecosystems to provide services depends on the concentration of available natural resources in the system at a large scale, but also on the ability of the ecosystems to capture natural resources in the same or similar environments. PMID- 30294537 TI - Evaluation of Glypican-3 expression in benign and malignant salivary gland tumors. AB - Introduction: Glypican-3 (GPC3) is involved in regulation of cell proliferation and morphogenesis. It is abundant in embryonic tissue, but limited in most adult tissues. GPC3 deletion or mutation can disturb the balance between cell apoptosis and proliferation, which may result in tumorigenesis. This study aimed to investigate the GPC3 expression in salivary gland tumors (SGTs) and the adjacent non-neoplastic tissues. Methods: This study reviewed 50 samples of salivary tumors from the archive of Khalili Hospital, Shiraz, Iran, including 17 cases of pleomorphic adenoma (PA), 16 cases of mucoepidermoid carcinoma (MEC), and 17 cases of adenoid cystic carcinoma (ACC); as well as a control group of 23 cases of normal salivary gland tissues. GPC3 expression was investigated through immunohistochemistry. Results: GPC3 expression was significantly higher in malignant tumors (MEC and ACC) than in PA, and higher in PA than in the normal salivary glands (P < 0.001). The expression intensity was moderate to strong in malignant tumors and weak to moderate in benign tumors. No strong positivity was observed in normal salivary gland tissues (P < 0.001). Nor was any association detected between the GPC3 expression and intensity with the clinicopathologic parameters. Conclusion: Although GPC3 overexpression was observed at the protein level in SGTs, and its expression was not related with the clinicopathologic factors, the potential use of GPC3 for diagnostic, therapeutic, and prognostic purposes requires further investigations. PMID- 30294539 TI - A devastating cardiovascular event in an adult cystic fibrosis patient: An unforeseen outcome of increasing life expectancy. AB - The improving life expectancy for CF is known to be one of the biggest success stories in medicine. Life expectancy has increased from 6 months during the early 20th century to 42.7 years from in 2012-2016. As the life expectancy of CF patients has increased, it is important to consider other co-morbidities that these patients may encounter, and the impact this may have on their morbidity and mortality. We present a case of a 33-year-old male admitted to the hospital for a CF exacerbation who had an acute neurological decompensation due to an infarction of his right occipital and posterior temporal lobe. PMID- 30294538 TI - A clinico-microbiologic study comparing the efficacy of locally delivered chlorhexidine chip and diode LASER as an adjunct to non-surgical periodontal therapy. AB - Background: Considering the microbial etiology of the periodontal disease, the periodontal therapy aims to control or abolish the pathogenic microbes. The gold standard scaling and root planing procedure has been used since time immemorial but the drawbacks associated with it have led to the development of various adjunctive means. The current study was therefore, performed to comparatively assess the efficacy of local delivery of chlorhexidine and 808-nm diode LASER as an appurtenance to scaling and root planing in patients with chronic periodontitis. Methods: In a randomized split mouth evaluation, 30 patients having probing depth of >=5 mm which bled on probing at least at 3 different sites were included. At baseline, the evaluation of plaque index, bleeding index, probing pocket depth and clinical attachment level was done and the microbial samples were collected for the assessment of spirochetes, motile rods and coccoid cells. The 3 selected sites of each subject were allocated to 3 different groups A, B, C viz; Scaling and root planing (SRP) + chlorhexidine chip, SRP + diode LASER and SRP respectively. The patients were recalled after 4 weeks to re evaluate the clinical and microbiological parameters. Results: All the parameters significantly reduced from baseline to 4 weeks in all the 3 groups. Intergroup comparisons revealed remarkable difference between group A and C and group B and C, respectively; no notably significant difference was found between group A and B. Conclusion: The additional use of LASER and chlorhexidine chip assures anti inflammatory effect and anti-microbial effect that allows reduction in bacterial counts and promotes healing. The use of adjuncts have been found to be efficacious in controlling disease and promoting periodontal health and thereby reducing the need for surgical procedures to be undertaken. PMID- 30294540 TI - A simple technique for thoracoscopic assisted placement of the distal limb of syringopleural shunts. AB - Background: Syringomyelia is an unusual accumulation of fluid within the spinal cord that may be associated with significant neurologic symptoms. Surgical drainage using various techniques is often required to reduce the intraparenchymal pressure and to alleviate symptoms. Syringopleural shunting seems to produce best results. Patients and methods: A simple technique to insert the distal limb of the syringopleural shunt into the pleural space is described in detail. The patient is placed in prone position. The syrinx is accessed from a dorsal incision and the proximal limb is inserted into the fluid cavity. The tube is tunneled through the subcutaneous space laterally and caudally. A 5mm blunt port is inserted lateral to the scapula and advanced under visual control using a 5mm 30 degrees camera through the subcutaneous tissue and muscle and at the upper border of the 5th rib through the intercostals. With ventilation paused, the pleura is penetrated and CO2 is insufflated with a pressure of 8mm mercury. Under visual control the distal limb of the shunt is inserted at the pleural recessus and the tube is directed cranially. Positive airway pressure is applied re-expanding the lung. The trocar is removed from the pleural cavity and the skin is closed with subcuticular sutures. Results: The shunt was successfully placed in three consecutive cases including one redo case (1 male, 1 female aged 50 and 51 years with post traumatic syrinx). Postoperative chest x-ray excluded pneumothorax and no chest tube was required. Neurologic improvement was achieved in both patients. Conclusions: General surgeons should be familiar with this simple technique similar to laparoscopic assisted placement of distal ventriculoperitoneal shunt catheters into the abdominal cavity.

AB - Since the raccoon (Procyon lotor) was introduced to Japan, studies have established that they are infested with native Japanese tick species. However, the quantity of ticks infesting raccoons is unknown. We conducted a survey of ticks on invasive raccoons captured on the Miura Peninsula, Kanagawa Prefecture, Japan, from April 2015 through June 2016 to determine the species of ticks and to quantify the intensity of tick infestation in order to obtain basal information related to the ecology of host-parasite relationships among indigenous tick species and an alien mammalian species. We collected and identified 15,931 ticks of two genera and six species, namely, Haemaphysalis flava, H. megaspinosa, H. longicornis, H. japonica, Ixodes ovatus, and I. tanuki, from 100 out of 115 raccoons. The dominant tick species was H. flava (96.8%) and individuals were mainly adults. Seasonal patterns of infestation intensity of adults and nymphs peaked in the autumn and winter and decreasing in the late spring and summer, May to August, while larvae peaked in August. Our results indicated that host parasite relationships between invasive raccoons and Japanese tick species, especially H. flava, were established in Kanagawa Prefecture. The ticks infest invasive raccoons for their blood-meal and also for overwintering. The results of this study extend our understanding of the ecology of tick-borne diseases.

PMID- 30294542 TI - The double-stage delay-multiply-and-sum image reconstruction method improves imaging quality in a LED-based photoacoustic array scanner. AB - Light-emitting diode-based photoacoustic imaging is more compact and affordable than laser-based systems, but it has low power and hence a high number of replicates. Here, we describe double-stage delay-multiply-and-sum (DS-DMAS) to improve image quality collected on a LED-based scanner. DS-DMAS was evaluated experimentally using point targets (in different laterals and depths) as well as a hair and a rabbit eye. This algorithm can compensate for the low SNR of LED based systems and offer better lateral resolution of about 60%, 25%, higher contrast ratio of about 97%, 34%, and better full-width-half-maximum of about 60%, 25%, versus delay-and-sum) and delay-multiply-and-sum, respectively. More importantly, DS-DMAS offers this using a smaller number of frames (only 2% of all the frames). These results indicate that DS-DMAS might be a valuable tool in the translation of LED-based and other low power PAI systems.

AB - Glucagon receptor (GCGR) defect (Mahvash disease) is an autosomal recessive hereditary pancreatic neuroendocrine tumor (PNET) syndrome that has only been reported in adults with pancreatic alpha cell hyperplasia and PNETs. We describe a 7-year-old girl with persistent hyperaminoacidemia, notable for elevations of glutamine (normal ammonia), alanine (normal lactate), dibasic amino acids (arginine, lysine and ornithine), threonine and serine. She initially was brought to medical attention by an elevated arginine on newborn screening (NBS) and treated for presumed arginase deficiency with a low protein diet, essential amino acids formula and an ammonia scavenger drug. This treatment normalized plasma amino acids. She had intermittent emesis and anorexia, but was intellectually normal. Arginase enzyme assay and ARG1 sequencing and deletion/duplication analysis were normal. Treatments were stopped, but similar pattern of hyperaminoacidemia recurred. She also had hypercholesterolemia type IIa, with only elevated LDL cholesterol, despite an extremely lean body habitus. Exome sequencing was initially non-diagnostic. Through a literature search, we recognized the pattern of hyperaminoacidemia was strikingly similar to that reported in the Gcgr -/- knockout mice. Subsequently the patient was found to have an extremely elevated plasma glucagon and a novel, homozygous c.958_960del (p.Phe320del) variant in GCGR. Functional studies confirmed the pathogenicity of this variant. This case expands the clinical phenotype of GCGR defect in children and emphasizes the clinical utility of plasma amino acids in screening, diagnosis and monitoring glucagon signaling interruption. Early identification of a GCGR defect may provide an opportunity for potential beneficial treatment for an adult onset tumor predisposition disease.

AB - Objective: Fasting Ramadan is associated with changes in lifestyle patterns of patients with diabetes who choose to perform fasting. We aimed to determine the attitude and habits of patients with type 1 diabetes during fasting Ramadan. Methods: The study comprised a prospective cohort of patients with type 1 diabetes who were on insulin pump or multiple daily insulin injections (MDI) regimen. Patient questionnaires included the frequency of self-monitoring of blood glucose (SMBG), the need to make changes in insulin regimen by patients, timings of insulin administration, performing carbohydrate counting and levels of physical activity. Results: A total of 156 patients were studied (61 patients on insulin pump and 95 patients on MDI). Patients on pump therapy performed SMBG more frequently than those on MDI regimen (4.8 +/- 1.4 and 3.7 +/- 1.7 times per day, respectively, P = 0.001) and were more likely to perform carbohydrate counting (32.7% and 8.4% of pump and MDI patients, respectively, P < 0.001). There was no difference in the percentage of patients who made changes in insulin doses (74.5% of the pump group and 77.3% of MDI patients) or those who had any level of physical activity (12.5% of the pump group and 21.1% of the MDI group). The timing of administering meal insulin in relation to sunset meal was variable with a preference to taking the injection immediately at sunset. There was no difference in glucose control between both groups as measured by frucotsamine levels or the number of days that patients have to stop fasting. Conclusion: Fasting Ramadan is associated with significant and variable changes in the attitude and behaviors of patients with type 1 diabetes with no difference in glucose control between patients on insulin pump or MDI regimen. Further studies are needed to define the role of education and its effect on these attitudes and patient care in this population.ClinicalTrials.gov Identifier: NCT01941238.

AB - Central hypothyroidism (CH) occurs approximately in 1:50,000, and therefore is expected to be one thousand times rarer compared with primary hypothyroidism. Despite its rarity in the general population, it is much more common in certain disorders, in which it is frequently associated with other pituitary hormone deficiencies. The aim of this paper is to provide an updated review on the frequency of congenital CH, which is <1:50,000, and on its etiology, disregarding CH caused by other genetic defects, such as mutations of transcription factors involved in pituitary organogenesis or mutations of the genes encoding TRH or TRH receptor. PMID- 30294555 TI - KALGAETM (Klebsormidium flaccidum var. ZIVO) dried algal biomass - 90-day dietary toxicity study and genotoxicity studies. AB - Consumers are demanding plant-based alternative protein sources to complement traditional animal-based protein sources to fulfill their dietary protein requirements. KALGAETM, a dried algal biomass derived from Klebsormidium flaccidum var. ZIVO, is a potential source of plant-based protein that has been evaluated for safety to support its use as a food ingredient. There were no treatment-related adverse effects observed in the 14-day palatability/toxicity or 90-day dietary toxicity study in CRL Sprague-Dawley CD(r) IGS rats. In the 90-day study, KALGAETM was administered to rats in the diet at 0, 37,500, 75,000, or 150,000 ppm. No adverse effects were attributed to the test substance for the following parameters: body weight, body weight gain, mean food consumption and efficiency, hematology, clinical chemistry, urinalysis, gross pathology, histopathology, or organ weights. Although some statistically significant effects were recorded, the effects were not considered to be of toxicological relevance. A No Observable Adverse Effect Level (NOAEL) of 150,000 ppm, equivalent to dietary intakes of 7895.2 (male) and 9708.09 (female) mg KALGAETM/kg body weight/day in rats was established. KALGAETM was non-mutagenic in the in vitro bacterial reverse mutation assay at concentrations up to 5000 MUg/plate (with or without S9 metabolic activation), nor was KALGAETM genotoxic in the in vivo mammalian erythrocyte micronucleus test in Swiss albino (ICR) mice. These results support the safe use of KALGAETM as an ingredient in foods.

AB - The current research aims to demonstrate the therapeutic effect of sour orange albedo extract (SOAE) and two flavanones loaded-tetraethylorthosilicate (TEOS) using sol-gel technique, in adose100 mg/kg body weight taken orally or45 days against acrylamide (ACR)toxicity in rats. This was achieved through measuring the activities of specific biochemical parameters related to liver functions in tissue of ACR intoxicated rats as compared to normal one. Liver functions included alanine and aspartate aminotransferases, antioxidants and oxidative stress biomarkers; superoxide dismutase, catalase, glutathione and lipid peroxide (malondialdehyde, MDA). Moreover, histological examination of liver was performed to confirm the biochemical findings. The present results clearly indicated disturbances in all biochemical parameters, such as increase in the liver function enzyme activities and MDA level. Results of ATPase enzyme activities revealed significant decrease in ACR intoxicated rats and liver biomarker enzymes declared significant decrease. On the other hand, treatment of intoxicated rats with the previous different nano-particles natural product demonstrated improvement in all biochemical parameters under investigation.

AB - This study reports the chemical investigation and bioactivity of the secondary metabolites produced by the endophytic fungus Fusarium solani isolated from Cassia alata Linn. growing in Bangladesh. This plant was collected from conservation forest in Bangladesh and belongs to the Caesalpiniaceae family. The endophytic fungus Fusarium solani was isolated from the tissue of root of this plant. The fungal strain was identified by morphological characters and DNA sequencing. The crude organic extract of the fungal strain was proven to be active when tested for cytotoxicity against Brine Shrimp Lethality Bioassay, antimicrobial and antioxidant activity. The bioactivity guided fractionation of the ethyl acetate extract leads to the isolation of seven secondary metabolites in pure form. The structures of the isolated compounds were determined by the analysis of NMR and mass spectroscopic data. Bioassay investigation of the isolated secondary metabolites suggested aza-anthraquinones are more potent bioactive compounds as anticancer and antimicrobial agent. PMID- 30294557 TI - Fetal hyperthyroidism associated with maternal thyroid autoantibodies: A case report. AB - A 33-year-old Caucasian woman was referred at 24 + 3 weeks of gestation due to fetal tachycardia and hydrops. She had an uncomplicated pregnancy 16 years previously and was on levothyroxine after total thyroidectomy for Graves' disease 6 years previously, when she developed moderate exophthalmos. Laboratory evaluation revealed appropriate thyroid function for this time of gestation: thyroid stimulating hormone (TSH) 1.7 MUU/ml (1-3), fT4 18.53 pmol/l (12-22), with positive antibodies: anti-TPO 157 U/ml (<35), TSH receptor antibodies (TRAb) 171.95 U/l (<1.75). The diagnosis was fetal hyperthyroidism due to transplacental passage of stimulating maternal TRAb. Methimazole and digoxin were initiated. The patient remained euthyroid, with fT4 levels in the upper normal range. The fetus showed intrauterine growth retardation, oligohydramnios, aggravating hydrops, goiter with increased central vascularization and improved heart rate without signs of cardiac failure. At 30 + 3 weeks a hydropic hyperthyroid male newborn (birthweight 1560 g) was delivered by cesarean section and admitted to the neonatal intensive care unit. Cord serum showed neonatal hyperthyroidism. Methimazole and propranolol were administered to the newborn. On the 5th postnatal day the infant died because of severe infection inducing respiratory dysfunction, hemodynamic deterioration and cardiac asystole. Graves' disease occurs in about 0.2% of pregnancies. Hyperthyroidism occurs in 1-5% of neonates born to mothers with Graves' disease and the risk correlates with the maternal TRAb titer. Early diagnosis and treatment are crucial not only in pregnant women with active disease, but also in mothers with a history of Graves' disease, even after definitive treatment such as thyroidectomy or ablative therapy. PMID- 30294558 TI - Standard method for microCT-based additive manufacturing quality control 3: Surface roughness. AB - The use of microCT of 10 mm coupon samples produced by AM has the potential to provide useful information of mean density and detailed porosity information of the interior of the samples. In addition, the same scan data can be used to provide surface roughness analysis of the as-built surfaces of the same coupon samples. This can be used to compare process parameters or new materials. While surface roughness is traditionally done using tactile probes or with non-contact interferometric techniques, the complex surfaces in AM are sometimes difficult to access and may be very rough, with undercuts and may be difficult to accurately measure using traditional techniques which are meant for smoother surfaces. This standard workflow demonstrates on a coupon sample how to acquire surface roughness results, and compares the results from roughly the same area of the same sample with tactile probe results. The same principle can be applied to more complex parts, keeping in mind the resolution limit vs sample size of microCT. PMID- 30294559 TI - Standard method for microCT-based additive manufacturing quality control 2: Density measurement. AB - MicroCT is best known for its ability to detect and quantify porosity or defects, and to visualize its 3D distribution. However, it is also possible to obtain accurate volumetric measurements from parts - this can be used in combination with the part mass to provide a good measure of its average density. The advantage of this density-measurement method is the ability to combine the density measurement with visualization and other microCT analyses of the same sample. These other analyses may include detailed porosity or void analysis (size and distribution) and roughness assessment, obtainable with the same scan data. Simple imaging of the interior of the sample allows the detection of unconsolidated powder, open porosity to the surface or the presence of inclusions. The CT density method presented here makes use of a 10 mm cube sample and a simple data analysis workflow, facilitating standardization of the method. A laboratory microCT scanner is required at 15 MUm voxel size, suitable software to allow sub-voxel precise edge determination of the scanned sample and hence an accurate total volume measurement, and a scale with accuracy to 3 digits. *MicroCT-based mean density measurement method.*Accurate volume measurement and scale mass.*10 mm cube sample allows standardization and automation of workflow.

AB - The rationale of the present study was to isolate and identify endophytic fungi from endemic medicinal plants in Eastern Ghats and screened for antimicrobial potential of isolated fungal crude extracts. A total of 329 endophytic strains were isolated from 600 infected leaves and stem cuttings of endemic plants. The diversity and species richness was analyzed statistically and found to be higher in leaf segments than in stem segments. From isolated fungal strains, Cladosporium delicatulum was identified using molecular identification methods and selected as the most potent plumbagin-producing endophytic strain. Further the isolation and structural characterization of endophytic fungal plumbagin (5 hydroxyl-2-methylnaptalene-1,4-dione) was purified and confirmed through spectroscopy analysis. The molecular weight was determined as m/z 188 in positive mode by ESI-MS, which confirmed to be plumbagin which potentially inhibited all tested pathogens, therefore the endophytic fungal plumbagin from the current study possesses important biological activities against pathogens.

PMID- 30294563 TI - Influence of Different Reference Databases on Categorization of Bone Mineral Density: A Study on Rural Postmenopausal Women from Southern India. AB - Background and Objectives: Currently available DXA (Dual energy X-ray Absorptiometry) scanners utilise bone mineral density (BMD) of Caucasian population to calculate T scores and categorise BMD. We studied the influence of various databases on classification of BMD in south-Indian postmenopausal women aged above 50 years. Methodology: This was a cross-sectional study. Hologic DXA scanner was used to estimate BMD at lumbar spine (LS) and femoral neck (FN). T scores of <=-2.5, -2.4 to -1, -0.9 to +1 were diagnostic of osteoporosis, osteopenia and normal respectively. Three reference databases(Italian, Korean and north Indian) were used to recalculate T scores. The agreement (K=kappa) between manufacturer provided database and the other databases was studied. The impact of different databases in diagnosing osteoporosis in subjects with FN fracture was assessed. Results: A total of 1956 postmenopausal women with mean (SD) age of 62 (4.3) years and 211 femoral neck(FN) fracture subjects with mean(SD) age of 68 (7.2) years were recruited. In subjects with fracture, osteoporosis at FN was found in 72% with Caucasian, 88% with North Indian, 56% with Italian, and 45% with Korean database. On comparing manufacturer provided database with the other population-specific reference, there was perfect agreement with north Indian (kappa = 0.81 [FN], kappa = 0.82 [LS]) and good agreement with the Italian database (kappa = 0.78 [FN], kappa = 0.74 [LS]). Conclusion: North-Indian database identified most of the participants with FN fracture as having osteoporosis and had perfect agreement with the manufacturer's database. Follow up studies will further validate the impact of utilizing this database in clinical practice.

AB - Background: Data on the effects of vitamin D supplementation on thyroid function in hypothyroid patients are scarce. Objective: This study was done to evaluate the effects of vitamin D supplementation on thyroid function in hypothyroid patients. Material and Methods: This randomized double-blind, placebo-controlled trial was conducted on 201 hypothyroid patients aged 20-60 years old. Subjects were randomly assigned into two groups to intake either 50,000 IU vitamin D supplements (n = 102) or placebo (n = 99) weekly for 12 weeks. Markers of related with thyroid function were assessed at first and 12 weeks after the intervention. Results: After 12 weeks of intervention, compared to the placebo, vitamin D supplementation resulted in significant increases in serum 25-hydroxyvitamin D (+26.5 +/- 11.6 vs. 0.0 +/- 0.0 ng/mL, P < 0.001) and calcium (+0.4 +/- 0.7 vs. 0.1 +/- 0.6 mg/dL, P = 0.002), and a significant decrease in serum thyroid stimulating hormone (TSH) levels (-0.4 +/- 0.6 vs. +0.1 +/- 2.0 MUIU/mL, P = 0.02). A trend towards a greater decrease in serum parathyroid hormone (PTH) levels was observed in vitamin D group compared to placebo group (-3.8 vs. +1.9, P = 0.07). We did not observe any significant changes in serum T3, T4, alkaline phosphatase (ALP) and albumin levels following supplementation of vitamin D compared with the placebo. Conclusion: Overall, the current study demonstrated that vitamin D supplementation among hypothyroid patients for 12 weeks improved serum TSH and calcium concentrations compared with the placebo, but it did not alter serum T3, T4, ALP, PTH, and albumin levels. PMID- 30294565 TI - Ultrasound Elastography is a Useful Adjunct to Conventional Ultrasonography and Needle Aspiration in Preoperative Prediction of Malignancy in Thyroid Nodules: A Northern India Perspective. AB - Introduction: Data on ultrasound elastography (USE) are scant from India. This study aimed to compare the sensitivity and specificity of USE with thyroid ultrasonography (USG) and fine-needle aspiration (FNA) as preoperative predictor of malignancy, using postoperative histopathology as gold standard. Materials and Methods: Consecutive patients with thyroid swelling/goiter underwent thyroid USG followed by USE. Patients with pure cystic nodules or eggshell calcification were excluded. Patients with nodules >10 mm with one or more high-risk USG features underwent FNA. Patients with no USG high-risk features, benign score on USE, and benign FNA were conservatively followed. All other patients underwent thyroidectomy. Results: 246 consecutive patients underwent USG. Data from 97 patients (117 nodules) were analyzed. Median age of patients was 43 years with 85.4% females. All patients with USE score-1 had benign USG and FNA characteristics. Of 86 nodules having USE score-2, 18.6% nodules were hypoechoic and 16.28% had microcalcification. Hypoechogenicity and microcalcifications were observed in 66.67% nodules with USE score-3. All nodules with USE score-4 and 5 were hypoechoic and had microcalcifications. Histopathology was benign in 84 and malignant in 33 patients. Occurrence of malignancy in USE scores 1-5 was 0, 4.65, 100, 90.5, and 100%, respectively. All eight nodules with diagnosis of follicular adenoma had preoperative USE score-2. The sensitivity of preoperative USG, USE, and FNA in picking up malignancy was 66.67, 87.88, and 69.70%, respectively. Specificity of USG, USE, and FNA in detecting thyroid malignancy was 88.10, 100, and 97.6%, respectively. False positivity rates for USG, USE, and FNA in diagnosing thyroid malignancy was 11.9, 0, and 2.4%, respectively. The overall diagnostic accuracy of USG, USE, and FNA cytology in this study was 82.05, 96.58, and 89.74%, respectively. Conclusion: USE may be better than USG for preoperative detection of malignancy in thyroid nodules. PMID- 30294566 TI - Ultrasound-guided Fine-needle Aspiration Cytology along with Clinical and Radiological Features in Predicting Thyroid Malignancy in Nodules >=1 cm. AB - Aims and Objectives: The aim of the study is to examine the adequacy and accuracy of ultrasound-guided fine-needle aspiration cytology (US-FNAC) in thyroid nodules >=1 cm and to analyze the clinical, sonological, and cytological features in predicting thyroid malignancy. Materials and Methods: US-FNAC was done on 290 patients from December 2013 to December 2014 by the radiologist. The Thyroid Imaging Reporting and Data System (TIRADS) was used to record the sonological features. FNAC samples were reported by a dedicated cytopathologist. Accuracy was calculated by comparing US-FNAC, clinical features and ultrasound (US) features for those who had final histopathology till April 2017. Results: The adequacy of US-FNAC in this study was 80.2%. Thyroidectomy was performed in 128/290 (44.1%). The sensitivity and specificity of US-FNAC in this study is 83.9 and 76.3%, respectively, with a positive predictive value of 85.2%, negative predictive value of 74.4%, and an accuracy of 81% in predicting malignancy in thyroid nodules >=1 cm. The malignancy rate in benign FNAC sample was 25% (10/40), and was 69% (8/13) in those with a follicular lesion of undetermined significance (FLUS). Around 80% of benign and 89% of FLUS had follicular variant of papillary carcinoma of thyroid (FVPTC). US-FNAC, a high TIRADS score, and US features such as marked hypoechogenicity, taller than wide, irregular margins, microcalcification, and clinical features, such as hard in consistency and significant cervical lymph nodes, were important in predicting malignancy (P < 0.001). Conclusions: The accuracy of US-FNAC in this study is 81%. The US-FNAC, a high TIRADS score, a hard thyroid nodule, and significant cervical lymph nodes are important in predicting malignancy. The accuracy rate in benign and atypia undetermined significance categories needs to improve in this study. Further research to help in decreasing false negative rates of FVPTC will help in increasing the accuracy of US-FNAC in the present study. PMID- 30294567 TI - Study of Pituitary Morphometry Using MRI in Indian Subjects. AB - Aim: To establish normative measurements of pituitary gland in Indian population. Material and Methods: In this cross-sectional study, we measured dimensions of pituitary gland in 482 (213 females and 269 males) Indian subjects with apparently normal pituitary gland function. Mid-sagittal T1-weighted image (T1 WI) on magnetic resonance imaging (MRI) was used to measure height and length of pituitary gland. Pituitary gland width was measured using coronal T1-WI and pituitary gland volume was calculated. Results: Mean height, length and calculated volume of pituitary gland was significantly higher in females compared to males (p = <0.001, P = 0.03 and P = <0.001, respectively) when all age groups were combined but pituitary gland width was not statistically different in male and female subjects. When subjects were divided into different age groups, except for 10-14 years age group where pituitary height was significantly higher in females as compared to male, no significant difference was observed between male and female in any of the parameters (height, length, width and volume). The mean pituitary gland height was 5.80 +/- 1.32 mm and 5.37 +/- 1.25 mm in female and male subjects, respectively. Females achieved peak pituitary gland height in 10 to 14-year age group, while males achieved their peak pituitary gland height in 15 to 19-year age group. Conclusion: Our study provides age and sex wise normative data for pituitary measurements derived from Indian population. PMID- 30294568 TI - An observational Prospective Study to Evaluate the Preoperative Risk Factors of New-onset Diabetes Mellitus after Renal Transplantation in a Tertiary Care Centre in Eastern India. AB - Objectives: This study aimed to determine the pre-transplant risk factors as independent predictors on the new-onset of diabetes mellitus after renal transplants (NODATs). Materials and Methods: A single-centred prospective real world observational study of 100 subjects who underwent renal transplantation over a period of 2 years. All known patients with diabetes were excluded from the study. NODAT was defined according to the American Diabetes Association definition. In addition to pre-transplant workup 2 days prior to transplant, post transplant follow-up done on weekly basis for 1st month, every 15th day from 1st month to 3rd month, monthly from 3rd month to 12th month. Each transplant patient followed up for 1 year post-transplant or for 6 months post-development of NODAT, whichever was later. All the pre-transplant variables namely body mass index (BMI), family history of diabetes mellitus (DM), HbA1c, fasting insulin level, fasting c-peptide level, serology for hepatitis B, C, serum magnesium level and pre-operative insulin ressistance were further compared between NODAT and non NODAT groups at the end of the study to assess their strength of associations. Results: Among the 100 subjects included in the study, 24 developed NODAT. Risk factors namely age, family history of DM, BMI, hepatitis B and C infection, total cholesterol, triglyceride level, pre-operative HbA1c, pre-operative insulin resistance and pre-diabetes were significantly higher, whereas beta-cell function, ABO compatibility and magnesium levels being significantly lower in NODAT cohort. Conclusion: The incidence of NODAT is quite high (24%). Risk of development of NODAT was related to traditional as well as novel risk factors. Key aspects lies in identifying patients at risk of developing NODAT, using traditional risk factors for early diagnosis and introducing interventions on modifiable risk factors for prevention and timely intervention. PMID- 30294569 TI - Effect of Implementation of ADA/AACE Guidelines on the Management of Hospitalized Hyperglycemic Patients Through Training of Residents: A Tertiary Care Center Study. AB - Background: Hyperglycemia is a common comorbidity in hospitalized patients and may add to adverse outcomes. Various associations have issued guidelines for optimal management of hyperglycemia in ill patients. This study aims to assess the adherence to current guidelines in inpatient setting and the impact of educational interventions on the improvement in adherence to guidelines as well as its effect on the level of blood sugar control and patient outcomes. Materials and Methods: It was a quasi-experimental pretest and posttest study and was done in three phases, viz., observation of current practices, intervention in the form of educational interventions, and its effect on change in practices and patient outcomes. Results: There was statistically significant 22% increase in the use of recommended insulin regimens (P = 0.028). The proportion of blood sugars within recommended range in the first 48 h, mean daily blood sugars, and the incidence of severe hyperglycemia improved in phase 3 vs phase 1 and was statistically significant. On comparing the subgroups, viz., those who followed and those who did not follow the guidelines, the results of the proportion of blood sugar in recommended range and proportions of blood sugar of more than 250 were found to be statistically significant. Conclusion: Dedicated educational interventions help in improving healthcare practices. According to current guidelines, rapid improvement in hyperglycemia and better glycemic control occur with adherence to protocol-based management of hyperglycemia. PMID- 30294570 TI - Neonatal Glycemic Status of Infants of Diabetic Mothers in a Tertiary Care Hospital. AB - Background: Diabetes is a common medical complication during pregnancy that results in significant neonatal morbidities. In infants of diabetic mothers (IDMs), hypoglycemia is a common complication. Objective: To study the neonatal hypoglycemia in IDMs in a tertiary care hospital. Settings and Design: A cross sectional study was done in postnatal ward in Bangladesh Institute of Research and Rehabilitation in Diabetic, Endocrine and Metabolic Disorders from January to December 2009. Subjects and Methods: The data of IDMs were collected from postnatal ward. All IDMs delivered during this period staying in postnatal ward were included in this study. The outcomes were compared between the hypoglycemic and normoglycemic IDMs and between gestational diabetes mellitus (GDM) and pre GDM in hypoglycemic group using Chi-square test and Fisher's exact test. The data analysis was performed with Epi-enfo7 software. Statistical significance was set at P < 0.05. Results: A total of 363 IDMs were included in this study. Hypoglycemia developed in 38.3% IDMs and 43.2% mothers of hypoglycemic IDMs had GDM and 56.8% had pre-GDM. Duration of maternal diabetes (P = 0.04) and large for gestational age (P = 0.0001) were associated with hypoglycemia. Multigravidae (82.2% vs 68.3%, P = 0.03), prolonged duration of maternal diabetes (45.46 weeks vs 3.23 weeks, P = 0.00001), preterm babies (48.1% vs 28.3% P = 0.009), and control of diabetes by insulin (81% vs 46.7%, P = 0.001) were more in pre-GDM, and statistically significant. About 85% IDMs developed hypoglycemia within 6 h of birth (P-value 0.00001) and majority (68%) were at 2 h of age. Forty percent of hypoglycemic IDMs from postnatal ward were admitted in special care baby unit. Conclusion: Hypoglycemia observed in 38.3% IDMs and developed within 6 h of age and maximum were at 2 h. Early recognition and appropriate intervention are needed in IDMs. PMID- 30294571 TI - Comparison of Efficacy and Safety of Fixed Dose Combination of Rosuvastatin and Choline Fenofibrate to Fixed Dose Combination of Rosuvastatin and Fenofibrate in Patients of Mixed Dyslipidemia: A Randomized, Open-label, Multicentre Clinical Trial in Indian Population. AB - Introduction: This study was conducted to evaluate the safety and efficacy of fixed-dose combination (FDC) of rosuvastatin and choline fenofibrate in comparison to rosuvastatin and fenofibrate FDC among Indian patients of mixed dyslipidemia. This would be a first study evaluating FDC of rosuvastatin and choline fenofibrate in Indian population. Methods: A multicenter, open-label, randomized, active controlled, comparative, parallel-design study was conducted at 12 centers spread all across India. Mixed dyslipidemic patients aged 18-70 years were randomized to FDC of rosuvastatin 10 mg and choline fenofibrate 135 mg (RCF group) and FDC of rosuvastatin 10 mg and fenofibrate 160 mg (RF group) once daily for approximately 180 days. The primary endpoint of study was percentage change in serum triglyceride level at the end of study from baseline. Results: Of 290 patients screened, 240 patients were enrolled in this study (120 patients in each group). At the end of 180 days, there was a significant reduction in triglyceride level in both the groups (-37.7% in RCF group and -37.8% reduction in RF group; P < 0.0001 for both); however, the difference between both the groups was not statistically significant (P = 0.94). Similarly, there was significant increase (P < 0.0001 for both) in high-density lipoprotein cholesterol (HDL-C) in both groups (+17.8% in RCF group and +14.9% in rosuvastatin fenofibrate RF group). Low-density lipoprotein cholesterol (LDL-C), very low-LDL (VLDL-C), and total cholesterol were also reduced significantly in both groups (P < 0.0001). However, the difference between two groups for increase in HDL-C and decrease in LDL-C, VLDL-C, and total cholesterol was not significant. Both the treatments were safe and well tolerated. Conclusion: Overall, FDC of rosuvastatin and choline fenofibrate is as safe and effective as rosuvastatin and fenofibrate combination in Indian patients with mixed dyslipidemia with added advantage improved patient compliance as it can be taken irrespective of intake of food. PMID- 30294572 TI - Effect of Glycemic Variability on Mortality in ICU Settings: A Prospective Observational Study. AB - Background: Evidence suggests a role of glycemic variability in intensive care unit (ICU) mortality. Objective: To assess effect of glycemic variability and ICU/in-hospital mortality. Design: Prospective, observational study. Setting: A 20-bedded medical/surgical ICU in a tertiary care hospital. Patients: Critically ill patients requiring life-support measures admitted to the ICU between November 1, 2015 and December 30, 2016 with hyperglycemia [random blood sugar (RBS) >=200 mg%] and sequential organ failure assessment (SOFA) scores <=9. Patients were put on predefined insulin infusion protocol, multiple glucose values were obtained, and mean blood glucose level (MGL) was calculated as their simple arithmetic mean. Standard deviation (SD) of MGL and coefficient of variation (CV) of glucose (derived as a percentage of SD to mean blood glucose) were then calculated for each patient and analyzed for all-cause death during hospitalization period. Results: A total of 123 patients having a mean age of 65.12 +/- 16.27 years, mean SOFA score of 5.76 +/- 1.76, and mean HbA1c of 6.22 +/- 0.73% were included. MGL was 160.65 +/- 24.19 mg/dl, SD 33.32 +/- 15.08 mg/dl, and CV 20.74 +/- 8.43. Deceased as compared to survivors had higher MGL (163.76 +/- 24.85 vs 155.62 +/- 22.43 mg/dl, P = 0.068) and higher glycemic variability (SD 38.92 +/- 14.44 vs 25.06 +/- 12.27 mg/dl; P < 0.001 and CV 23.69 +/- 7.9 vs 15.98 +/- 6.87; P < 0.001). Interestingly, more patients having higher CV at lower MGL (85.7%) died as compared to those having lower CV at higher MGL (55.6%). Conclusions: High glycemic variability is associated with increased ICU/in-hospital mortality. Outcome of patients having less glycemic variability even with slight hyperglycemia may be better than those having tight glycemic control but higher glycemic variability. Insulin protocols need to be in place for management of hyperglycemia in critical care setting aiming for adequate glycemic control as well as minimizing glycemic variability. PMID- 30294573 TI - It is Time to Carpe Diem with Porcine ACTH - A Comparison of Porcine Sequence Corticotropin to Tetracosactide Hexaacetate in Testing the Hypothalamic Pituitary Adrenal Axis in Healthy Individuals. AB - Context: Our literature search revealed that the use of porcine sequence corticotropin has not been validated against tetracosactide hexaacetate in a healthy population. Aims: To study the efficacy of using porcine sequence corticotropin in comparison with tetracosactide hexaacetate in the evaluation of hypothalamo pituitary adrenal (HPA) axis. Materials and Methods: Fifteen healthy volunteers were enrolled. Serum cortisol was measured at 0 minute in all subjects and at 30 and 60 minutes after tetracosactide hexaacetate 250 MUg intravenously. Four weeks later, serum cortisol level was measured at 0 minute and at 30 and 60 minutes following 24 units of porcine sequence corticotropin given intramuscularly. Results: Mean serum cortisol values with tetracosactide were 30.3 (+/-7.83) MUg/dl and 31.27 (+/-7.36) MUg/dl at 30 and 60 minutes, respectively. The mean cortisol values with porcine sequence corticotropin were 26.33 (+/-5.47) MUg/dl and 31.59 (+/-6.40) MUg/dl at 30 and 60 minutes, respectively. All subjects had a response qualified as normal or adequate at 30 minutes itself. Mean peak serum cortisol response was 32.65 (+/-7.76) MUg/dl in tetracosactide group and 31.59 (+/-6.4) MUg/dl in porcine sequence corticotropin group, and the responses in two groups were comparable (P = 0.686). There were no immediate side effects in both groups, with a lower cost of procedure in the porcine corticotropin group. Conclusion: Our study established the efficacy of porcine sequence corticotropin in testing the adequacy of HPA axis in healthy individuals. Our study also revealed that, the intactness of the HPA axis could be confirmed as early as 30 minutes in healthy individuals. PMID- 30294574 TI - Epicardial Adipose Tissue Thickness and its Corelation with Metabolic Risk Parameters in People Living with HIV: A RIMS Study. AB - Context: Epicardial fat envelopes the coronary vessel adventitia without fascial separation, thus pathologic inflammation in the fat may promote the growth of atherosclerotic plaque in coronary arteries in an 'outside-in' fashion. Epicardial fat is quantitatively increased in HIV compared to un-infected people. Aims: 1. To assess Epicardial Adipose tissue (EAT) by Computed tomography (CT) in PLHIV receiving first line ART (antiretroviral therapy) 2. To correlate EAT with metabolic risk parameters. Material and Methods: 215 HIV-infected patients aged >18 years on first line ART were included in the cross sectional study. EAT thickness were measured by CT scan. Metabolic parameters were measured based on metabolic syndrome criteria. Statistical Analysis Used: Data analysis was done using IBM SPSS version ver. 21. Probability value of less than 0.5 was taken as significant. Ethical Issues: The study was carried out after obtaining approval from the Institutional Ethical Committee (IEC), Regional Institute of Medical Sciences, Imphal. Results: Half of the patients were found to have EAT thickness of 8.1-9 mm and 12.6% of cases had EAT of >9 mm. Mean epicardial thickness was 8.3 mm +/- 0.7 mm for whole population. Triglyceride and high density lipoprotein (HDL) were also found to have positive correlation with EAT thickness (rp= 0.364, P = 0.04 and rp= 0.343, P = 0.05 respectively). Conclusion: Epicardial adipose tissue thickness is increased in PLHIV receiving highly active anti retroviral therapy (HAART) and positively co-related with parameters of metabolic syndrome such as waist circumference, HDL cholesterol and triglyceride level. PMID- 30294575 TI - A Study of Thyroid Dysfunction in Cirrhosis of Liver and Correlation with Severity of Liver Disease. AB - Introduction: Liver plays an important role in the metabolism of thyroid hormones, as it is the most important organ in the peripheral conversion of tetraiodothyronine (T4) to triiodothyronine (T3) by Type 1 deiodinase. Materials and Methods: This case-control study included 100 decompensated liver cirrhosis patients (71 males and 29 females) and 100 apparently healthy controls (71 male and 29 female). Serum FT3, FT4, and thyroid-stimulating hormone (TSH) levels were measured using electrochemiluminescence immunoassay and analyses between cases versus healthy controls (Group 1) and further analyses in subgroups, cirrhosis with hepatic encephalopathy (HE) cases (n = 38) versus cirrhosis without HE cases (Subgroup 1), cirrhosis survivors (n = 84) versus cirrhosis nonsurvivors (Subgroup 2), HE survivors (n = 23) versus HE nonsurvivors (Subgroup 3). Results were also analyzed for severity of liver disease according to Child-Turcotte-Pugh (CTP) (Class A, B, and C), model for end-stage liver disease (MELD) score, and HE grades. Results: Most common etiology was alcohol (46%) and presentation was gross ascites (74%). Cirrhosis patients had statistically significant lower level of FT3 (P < 0.0001) and FT4 (P < 0.0001) but had higher level of TSH (P < 0.0001) compared with the controls. Cirrhosis with HE (n = 38) had significantly lower lever of FT3 (P < 0.0001) compared with cirrhosis without HE (n = 62), whereas there was no statistically significant difference in FT4 (P < 0.09) and TSH (P < 0.60) levels. FT3 level significantly low in HE Grade 4 patients compared with HE Grade 1 patients (P = 0.0001). In all cirrhotic patients, FT3 and FT4 were negatively correlated, but TSH level was positively correlated with total leukocyte counts, serum total bilirubin, aspartate transaminase, alanine transaminase, globulin, prothrombin time (PT), blood urea, serum creatinine, CTP, and MELD score. Overall, the most common abnormality seen was low T3 (low FT3) syndrome 41% (41 out of 100) in cases, 50% (19 out of 38) in cirrhosis with HE, and 32% (5 out of 16) in Non-survivors cases. Conclusion: The mean FT3 and FT4 levels were significantly decrease and mean TSH levels were significantly increase in liver cirrhosis patients compared to healthy controls. Level of FT3, FT4, and TSH also correlate with the severity of liver disease, level of FT3 can be used as prognostic marker for liver cirrhosis patients. PMID- 30294576 TI - Correlation between Ultrasound-based TIRADS and Bethesda System for Reporting Thyroid-cytopathology: 2-year Experience at a Tertiary Care Center in India. AB - Background: In recent times, high-resolution ultrasound thyroid imaging has paved the way for significant transformation in clinical approach to thyroid nodule. There are several risk stratification systems in thyroid imaging, developed with an aim, not only to reduce the inter-observer variability but also to establish effective communication system. Thyroid image reporting and data system (TIRADS) classification system, which is similar to breast imaging reporting and data system for breast lesion, is the most useful of all. To our knowledge, there is just a handful published research articles available based on Indian population in this regard. In this article, we study the thyroid nodules using high resolution ultrasound in Indian population and we try to correlate the TIRADS and Bethesda system for reporting thyroid cytopathology. Materials and Methods: This prospective study includes 184 patients studied over a period of 2 years (April 2015-April 2017). Patients having thyroid nodule in B-mode ultrasound and are scheduled to get a fine-needle aspiration cytology (FNAC) done. Bethesda classification of these nodules is tabulated in follow-up period simultaneously. By comparing these data, efficacy of TIRADS in differentiating benign from malignant nodules are assessed finally using accuracy, positive predictive value (PPV), cross-tabulation, and Chi-square tests. Results: Out of the 117 TIRADS 2 nodules, none turned out to be Bethesda IV or higher, which means none of these nodules turned out to be malignant. The risk of malignancy for TIRADS 2, TIRADS 3, TIRADS 4, and TIRADS 5 was 0, 2.2, 38.5, and 77.8%, respectively. The risk of malignancy percentage in our study is similar to those values obtained in other prominent studies. Conclusion: The probability of a particular nodule being malignant can be effectively inferred from the ultrasound-based TIRADS system with a certain level of confidence. Considering our results and other literature reviews, it be can be safely assumed that FNAC can be at least deferred in patients having TIRADS 2 nodules, which contribute to majority of newly detected cases. In our experience, there is a remarkable correlation exists between TIRADS ultrasound classification and Bethesda cytology, especially for benign nodules. PMID- 30294577 TI - Association of Hypomagnesemia with Hypocalcemia after Thyroidectomy. AB - Background: Hypocalcemia is one of the most common acceptable complications in postoperative period after thyroidectomy. Hypomagnesemia has been recognized after parathyroid surgery, and it has not been studied extensively after thyroidectomy. The aim of this study was to estimate magnesium and calcium ion levels in patients undergoing thyroidectomy and to evaluate the association of hypomagnesemia with hypocalcemia after thyroidectomy. A prospective study was conducted in Government Medical College, Calicut, from December 2012 to November 2013. Materials and Methods: all patients had undergone total/near-total/subtotal thyroidectomy. Pre- and postoperative at 24 h and serum calcium and magnesium were measured by automate electrolyte analyzer. Clinical findings of hypocalcemia were recorded. Statistical analysis was done using SPSS software, version 17.0. Unpaired student t-test was used. Pearson Chi-square test or Fisher's exact test was used to compare the percentage for categorical variables. Results: In our study, 58% of the patients developed hypocalcemia, biochemical and/or symptomatic (S. Ca <8.5). About 34% of patients developed hypomagnesemia, biochemical and/or symptomatic (S. Mg <1.7). About 30% of patients developed both hypocalcemia and hypomagnesemia. About 24% of patients developed symptoms of both hypocalcemia and hypomagnesemia. Discussion: Thyroidectomy patients were at a risk of transient and permanent hypoparathyroidism because of chances of parathyroid resection during operation. Transient hypocalcemia and hypomagnesemia occur frequently after total thyroidectomy. It is important to monitor both calcium and magnesium levels after total thyroidectomy and to correct deficiencies to facilitate prompt resolution of symptoms. Conclusion: There is an association of hypomagnesemia with hypocalcemia after thyroidectomy. PMID- 30294578 TI - Effect of Physical Activity during Pregnancy on Gestational Diabetes Mellitus. AB - Aims: The present study evaluates association between physical activity and Gestational Diabetes Mellitus (GDM), for it can be an effective intervention for its management. Though physical activity helps maintain glucose homeostasis, evidences of GDM risk are less extensive. Therefore, this study also identifies its correlation with maternal blood glucose levels. Materials and Methods: A prospective case-control study was carried out among pregnant women attending regular antenatal clinic at two private hospitals. The study comprised of 100 cases and 273 matched controls. Data was collected by personal interviews using a standard questionnaire. Physical activity was assessed using long form of International Physical Activity Questionnaire (IPAQ) reported as Metabolic Equivalent-Minutes per week (MET-Minutes/Week). Statistical Package for Social Sciences (SPSS) was used for analysis. Results: Results shows high exposure rates for low-to-moderate physical activity among cases, across all domains and sub activities. The odds of GDM engaged in domestic and gardening activities for <2999 MET-minutes per week are 10 times higher than involved for >=3000 MET minutes per week (P < 0.001). The study also shows poor or no correlation between physical activity during pregnancy and maternal blood glucose levels. Conclusion: Despite existence of poor or no relationship with maternal blood glucose levels, prolonged sedentary behavior and decreased physical activities, especially domestic, are potential risk factors for GDM, a major finding of the study. PMID- 30294579 TI - Impact of Glycemic Levels in Type 2 Diabetes on Periodontitis. AB - Aim: The aim is to study the effect of glycemic level in Type 2 diabetes and cardiovascular risk factors on periodontal health. Materials and Method: Type 2 diabetic and nondiabetic patients in the age group of 35-80 years (n = 1700) were recruited for the study. Periodontal examination included as follows: Probing depth, clinical attachment level (CAL), gingival recession, and bleeding on probing. Periodontitis was diagnosed based on the CAL levels and diabetes was diagnosed based on glycated hemoglobin (HbA1c) levels. Body mass index, total cholesterol, triglyceride, and low-density lipoprotein (LDL) were assessed for cardiovascular risk. Patients were characterized into two groups as follows: diabetic (n = 1235) and nondiabetic (n = 465). Sociodemographic variables included were: age, sex, obesity, smoking, duration of diabetes, and periodontitis were assessed. SPSS version 20.0.1.0 was used for all the statistical assessments. Conclusion: HbA1c and lipid levels were statistically significant with the severity of periodontitis (odds ratio [OR] [95% confidence interval [CI]: HbA1c 1.34 [1.019-1.21]; Total cholesterol 1.01 [1.03-1.42]; triglycerides 1.01 [1.01-1.14]; LDL 1.028 [1.08-1.71]). Smoking and obesity were also found to be significantly associated with the presence of periodontitis [OR (95% CI): smoking 1.35 (1.10-1.67); obesity 1.23 (1.73-2.05)]. The study concluded that uncontrolled HbA1c levels and elevated cardiovascular risk factors significantly increase the severity of periodontitis in Type 2 diabetes mellitus. PMID- 30294580 TI - Serum Uric Acid Levels in Type 2 Diabetes Mellitus: Is There a Linear Relationship with Severity of Carotid Atherosclerosis? AB - Aims: The aim of this study was to correlate serum uric acid (SUA) levels and carotid intima-media thickness (CIMT) in patients with type 2 diabetes mellitus (DM). Settings and Design: This study was a cross-sectional observational study on 103 diabetic patients conducted from September 2015 to May 2017. Subjects and Methods: We screened 103 patients with type 2 DM between the ages of 30-65 years. SUA levels and the CIMT were measured. The patients were divided into quartiles based on uric acid level. The CIMT of the quartiles is compared and analyzed. Statistical Analysis Used: Chi-squared test, Analysis of Variance, and Pearson's correlation. Results: Uric acid levels were positively associated with CIMT (P = 0.001). The association remained significant after further adjustment for potential confounders. Strong correlation was found among them as depicted by correlation coefficient (r = 0.779). Conclusions: Carotid atherosclerosis as measured by IMT is associated with SUA levels in patients with type 2 DM. PMID- 30294581 TI - Serum Amyloid P and Endocrine Markers in a Cohort of Obese Children. AB - Objectives: Obesity in children can lead to morbidity and mortality due to metabolic and inflammatory comorbidities. Aims: The objective of the study was to investigate the alterations in acute inflammatory markers, serum amyloid P (SAP) and cortisol, and endocrine markers, leptin and insulin, in obese children. Materials and Methods: Serum leptin, insulin, cortisol, and amyloid P concentrations were measured in obese (BMI percentile >85, n = 17) and nonobese (BMI percentile < 75, n = 20) children using ELISA and Bio-Plex Bead-based assay. Statistical Analysis Used: Serum concentrations of analytes were compared between normal and obese groups using 2-tailed student's t-test. Results: Mean leptin, insulin, and SAP serum concentrations were significantly higher in obese children as compared to the controls (97.19 vs. 4.06, P < 0.05; 21.31 vs 3.56, P < 0.05; 46.77 vs. 17.89, P < 0.05; respectively). No difference was found in mean serum cortisol levels of the two groups. However, cortisol values were higher in obese subjects compared to the control group (7.89 vs 6.30, P = 0.15). Leptin corelated with insulin (r = 0.42, P = 0.043) and cortisol (r = 0.48, P = 0.025) levels in the obese group. Furthermore, leptin, insulin, and SAP levels were corelated with BMI (r = 0.80, P < 0.000; r = 0.67, P = 0.015, respectively) and body weight (r = 0.52, P = 0.01; r = 0.52, P = 0.002; r = 0.54, P = 0.01, respectively) in the obese group but did not demonstrate a significant relationship in the nonobese group. Conclusion: Elevated SAP levels and increase in leptin and insulin indicated a preeminent disposition of morbidly obese children to the development of low-grade inflammation and metabolic syndrome. PMID- 30294582 TI - A Review on Cardiovascular Outcome Studies of Dipeptidyl Peptidase-4 Inhibitors. AB - The U.S. Food and Drug Administration issued a guidance for pharmaceutical industry defining preapproval and postapproval requirements for the demonstration of cardiovascular (CV) safety for all new medications developed for glycemic management in type 2 diabetes. However, results published from the studies of dipeptidyl peptidase-4 (DPP-4) inhibitors are conflicting with regard to different CV endpoints. Upcoming CV outcome studies perhaps will be able to provide additional insights related to diabetes management and help to provide the answers to some of these concerns. This article provides a brief overview regarding how various CV safety evidence of DPP-4 inhibitor evolved over time that highlights possible implication in clinical practice and translates them into effective diabetes management. PMID- 30294584 TI - PHPT Masquerading as Rickets in Children and Presenting with Rare Skeletal Manifestations: Report of Three Cases and Review of Literature. AB - Primary hyperparathyroidism (PHPT) is an uncommon condition in children and adolescents. However, rapid growth spurt during puberty may result in unmasking and development of certain skeletal manifestations of PHPT. We present three cases of PHPT associated with rare skeletal manifestations of rickets. All three patients had radiological evidence of rickets with primary hyperparathyroidism. All the three patients had single gland adenoma. Literature is sparse regarding reversal of features of rickets following parathyroidectomy. In all three patients of our series, there was a complete resolution of bone/joint pain. However, in two children only the genu valgum persisted but their growth was normal and they had no proximal muscle weakness. In another child multiple corrective surgeries were done to correct the deformities. PMID- 30294585 TI - Bilateral Femoral Head Avascular Necrosis with Physiological Doses of Steroids.

PMID- 30294583 TI - Emotional and Psychological Needs of People with Diabetes. AB - Diabetes is a chronic metabolic disorder that impacts physical, social and mental including psychological well-being of people living with it. Additionally, psychosocial problems that are most common in diabetes patients often result in serious negative impact on patient's well-being and social life, if left un addressed. Addressing such psychosocial aspects including cognitive, emotional, behavioral and social factors in the treatment interventions would help overcome the psychological barriers, associated with adherence and self-care for diabetes; the latter being the ultimate goal of management of patients with diabetes. While ample literature on self-management and psychological interventions for diabetes is available, there is limited information on the impact of psychological response and unmanaged emotional distresses on overall health. The current review therefore examines the emotional, psychological needs of the patients with diabetes and emphasizes the role of diabetologist, mental health professionals including clinical psychologists to mitigate the problems faced by these patients. Search was performed using a combination of keywords that cover all relevant terminology for diabetes and associated emotional distress. The psychological reactions experienced by the patient upon diagnosis of diabetes have been reviewed in this article with a focus on typical emotional distress at different levels. Identifying and supporting patients with psychosocial problems early in the course of diabetes may promote psychosocial well-being and improve their ability to adjust or take adequate responsibility in diabetes self management - the utopian state dreamt of by all diabetologists !.

PMID- 30294590 TI - Detection of the MYD88 p.L265P Mutation in the CSF of a Patient With Secondary Central Nervous System Lymphoma. AB - Primary Central Nervous System Lymphoma (PCNSL) and Metastatic (or Secondary) Central Nervous System Lymphoma (MCNSL) are rare central nervous system (CNS) malignancies that exhibit aggressive clinical behavior and have a poor prognosis. The majority of CNS lymphomas are histologically classified as diffuse large-B cell lymphoma (DLBCL). DLBCL harbors a high frequency of mutations in MYD88 and CD79b. The MYD88 p.L265P mutation occurs at high frequency in CNS lymphoma and is extremely rare in non-hematologic malignancies. Currently, brain biopsy is considered the gold standard for CNS lymphoma diagnosis. However, brain biopsy is invasive, carries a risk of complications, and can delay initiation of systemic therapy. Circulating tumor DNA (ctDNA) in the cerebrospinal fluid (CSF) can be utilized to detect tumor-derived mutations. Testing of CSF-ctDNA is a minimally invasive methodology that can be used to assess the genomic alterations present in CNS malignancies. We present a case of an 82-year-old man with a history of testicular lymphoma who presented with speech difficulty and a multifocal enhancing left inferior frontal mass. Analysis for both CSF-cytology and flow cytometry did not show evidence of neoplastic cells. A brain biopsy was performed and microscopic examination showed DLBCL. We isolated CSF-ctDNA and used droplet digital PCR (ddPCR) to detect the most common lymphoma-associated mutations in MYD88, L265P, and V217F. In conjunction, we evaluated the patient-matched CNS lymphoma tissue for MYD88 mutations. We detected the MYD88 p.L265P mutation in formalin fixed paraffin embedded (FFPE) tissue from the brain biopsy and the CSF ctDNA. In contrast, both the tumor tissue and the CSF ctDNA were negative for the MYD88 p.V217F mutation. This study shows that testing CSF ctDNA for MYD88 mutations is a potentially minimally-invasive approach to diagnosing patients with suspected CNS lymphomas. PMID- 30294591 TI - The Formin mDia1 Regulates Acute Lymphoblastic Leukemia Engraftment, Migration, and Progression in vivo. AB - Leukemias typically arise in the bone marrow and then spread to the blood and into other tissues. To disseminate into tissues, leukemia cells migrate into the blood stream and then exit the circulation by migrating across vascular endothelial barriers. Formin proteins regulate cytoskeletal remodeling and cell migration of normal and malignant cells. The Formin mDia1 is highly expressed in transformed lymphocytes and regulates lymphocyte migration. However, the role of mDia1 in regulating leukemia progression in vivo is unknown. Here, we investigated how mDia1 mediates the ability of leukemia cells to migrate and disseminate in vivo. For these studies, we used a mouse model of Bcr-Abl pre-B cell acute lymphoblastic leukemia. Our data showed that mDia1-deficient leukemia cells have reduced chemotaxis and ability to complete transendothelial migration in vitro. In vivo, mDia1 deficiency reduced the ability of leukemia cells to engraft in recipient mice. Furthermore, leukemia dissemination to various tissues and leukemia progression were inhibited by mDia1 depletion. Finally, mDia1 depletion in leukemia cells resulted in prolonged survival of recipient mice in a leukemia transfer model. Overall, our data show that the Formin mDia1 mediates leukemia cell migration, and drives leukemia engraftment and progression in vivo, suggesting that targeting mDia1 could provide a new method for treatment of leukemia. PMID- 30294592 TI - Gene Expression Signatures Can Aid Diagnosis of Sexually Transmitted Infection Induced Endometritis in Women. AB - Sexually transmitted infection (STI) of the upper reproductive tract can result in inflammation and infertility. A biomarker of STI-induced upper tract inflammation would be significant as many women are asymptomatic and delayed treatment increases risk of sequelae. Blood mRNA from 111 women from three cohorts was profiled using microarray. Unsupervised analysis revealed a transcriptional profile that distinguished 9 cases of STI-induced endometritis from 18 with cervical STI or uninfected controls. Using a hybrid feature selection algorithm we identified 21 genes that yielded maximal classification accuracy within our training dataset. Predictive accuracy was evaluated using an independent testing dataset of 5 cases and 10 controls. Sensitivity was evaluated in a separate test set of 12 women with asymptomatic STI-induced endometritis in whom cervical burden was determined by PCR; and specificity in an additional test set of 15 uninfected women with pelvic pain due to unknown cause. Disease module preservation was assessed in 42 women with a clinical diagnosis of pelvic inflammatory disease (PID). We also tested the ability of the biomarker to discriminate STI-induced endometritis from other diseases. The biomarker was 86.7% (13/15) accurate in correctly distinguishing cases from controls in the testing dataset. Sensitivity was 83.3% (5/6) in women with high cervical Chlamydia trachomatis burden and asymptomatic endometritis, but 0% (0/6) in women with low burden. Specificity in patients with non-STI-induced pelvic pain was 86.7% (13/15). Disease modules were preserved in all 8 biomarker predicted cases. The 21-gene biomarker was highly discriminatory for systemic infections, lupus, and appendicitis, but wrongly predicted tuberculosis as STI-induced endometritis in 52.4%. A 21-gene biomarker can identify asymptomatic women with STI-induced endometritis that places them at risk for chronic disease development and discriminate STI-induced endometritis from non-STI pelvic pain and other diseases. PMID- 30294593 TI - OmpR-Mediated Transcriptional Regulation and Function of Two Heme Receptor Proteins of Yersinia enterocolitica Bio-Serotype 2/O:9. AB - We show that Yersinia enterocolitica strain Ye9 (bio-serotype 2/O:9) utilizes heme-containing molecules as an iron source. The Ye9 genome contains two multigenic clusters, hemPRSTUV-1 and hemPRST-2, encoding putative heme receptors HemR1 and HemR2, that share 62% amino acid identity. Expression of these proteins in an Escherichia coli mutant defective in heme biosynthesis allowed this strain to use hemin and hemoglobin as a source of porphyrin. The hemPRSTUV-1 and hemPRST 2 clusters are organized as operons, expressed from the phem-1 and weaker phem-2 promoters, respectively. Expression of both operons is negatively regulated by iron and the iron-responsive transcriptional repressor Fur. In addition, OmpR, the response regulator of two component system (TCSs) EnvZ/OmpR, represses transcription of both operons through interaction with binding sequences overlapping the -35 region of their promoters. Western blot analysis of the level of HemR1 in ompR, fur, and ompRfur mutants, showed an additive effect of these mutations, indicating that OmpR may regulate HemR expression independently of Fur. However, the effect of OmpR on the activity of the phem-1 promoter and on HemR1 production was observed in both iron-depleted and iron-replete conditions, i.e., when Fur represses the iron-regulated promoter. In addition, a hairpin RNA thermometer, composed of four uracil residues (FourU) that pair with the ribosome binding site in the 5'-untranslated region (5'-UTR) of hemR1 was predicted by in silico analysis. However, thermoregulated expression of HemR1 could not be demonstrated. Taken together, these data suggest that Fur and OmpR control iron/heme acquisition via a complex mechanism based on negative regulation of hemR1 and hemR2 at the transcriptional level. This interplay could fine-tune the level of heme receptor proteins to allow Y. enterocolitica to fulfill its iron/heme requirements without over-accumulation, which might be important for pathogenic growth within human hosts. PMID- 30294594 TI - Astragalus Oral Solution Ameliorates Allergic Asthma in Children by Regulating Relative Contents of CD4+CD25highCD127low Treg Cells. AB - Objective: To explore the effects of Astragalus oral solution (AOS) on allergic asthma in children by investigating relative contents of CD4+CD25highCD127low Treg cells. Methods: The contents of Astragaloside A in AOS were detected by using HPLC. Eighty children with allergic asthma were recruited from February 2016 to June 2017, and randomly assigned into the control group (received placebo, 0.1% quinine chloride in deionized water, daily) and the AOS group (received 10 mL AOS daily). After 6-month treatment, therapeutic results were compared between the two groups. Serum levels of IL-10 and TGF-beta, Th1 cytokines (IL-2 and IFN-gamma), and Th2 cytokines (IL-4 and IL-6) were measured by using ELISA kits. Relative contents of CD4+CD25highCD127low Treg cells were determined by using flow cytometry. Results: Astragaloside A was the main ingredient of AOS with 0.216 +/- 0.027 mg/mL from six-batch samples. After 6 month therapy, the AOS group showed improved forced expiratory volume in 1 s (FEV1) and the Pediatric Asthma Quality of Life Questionnaire (PAQLQ) scores compared with the control group (P < 0.05). Serum level of IL-10 was higher and the levels of TGF-beta, Th1 cytokines (IL-2 and IFN-gamma), and Th2 cytokines (IL 4 and IL-6) were lower in the AOS group than in the control group (P < 0.05). AOS treatment increased the percentage of gated CD4+ T cells, CD4+CD25+ T cells, CD4+CD25high Treg cells, CD4+CD25+FoxP3+ Treg cells and CD4+CD25highCD127low Treg cells when compared with the control group (P < 0.05). Conclusions: Astragaloside A was the main component of AOS, and AOS ameliorated allergic asthma in children by regulating relative contents of CD4+CD25highCD127low Treg cells. PMID- 30294595 TI - Impact of Chronic Medical Conditions on Academics of Children in the Child Welfare System. AB - Objective: Children in the Child Welfare System (CWS) are at high risk for multiple adverse outcomes. Since involvement in CWS and having a chronic medical condition are both risk factors for poor academic achievement, a logical view is that the combination is additive, increasing the odds of poor performance. However, several factors may complicate such an association. This study explores negative and positive factors that could affect academic achievement in children in CWS with chronic medical conditions. Method: In a secondary data analysis of a nationally representative, longitudinal sample of children in CWS (N = 5,501), subjects were divided into three groups based on chronic medical condition: High Prevalence, Low Severity (HPLS; asthma, eczema, allergy, diabetes), Other (OTH; all other chronic conditions, including those with primary central nervous system involvement), and NONE (children with no chronic condition). Using weighted analyses, hierarchical logistic regression models addressed factors associated with academic achievement. Predictor variables included chronic condition group, sex, income level, case substantiation, home placement, and school engagement. Intelligence quotient was a covariate. Outcome variables were strong performances for reading and math, defined by standard score >=85. Results: In TOTAL group, 80% had strong reading; more in HPLS (85%) vs. NONE (79%) and OTH (80%), adjusted F = 433, p < 0.001. In TOTAL group, 67% had strong math; more in NONE (68%) and HPLS (68%) vs. OTH (60%), adjusted F = 1,278, p < 0.001. Models predicting to strong reading and math achievement were significant, R 2 = 0.51, p < 0.001 and R 2 = 0.43, p < 0.001, respectively. HPLS had increased odds of strong reading achievement (aOR 1.3, 95% CI 1.3-1.4); both HPLS and OTH had lower odds of strong math achievement (aOR 0.87 and 0.76), p < 0.001, respectively. Male sex had lower odds of strong reading (aOR 0.44) and math achievement (aOR 0.62); positive school engagement had higher odds of strong reading (aOR 1.18) and math achievement (aOR 2.04), all p < 0.001. Conclusion: If true, our findings challenge the general belief that chronic illness can only be associated with negative outcomes and that cumulative adversities are simply additive in terms of risk. Increased contact with the medical system may provide an opportunity for improving reading achievement for children in CWS and promoting positive school engagement. PMID- 30294596 TI - Producing 3D Biomimetic Nanomaterials for Musculoskeletal System Regeneration. AB - The human musculoskeletal system is comprised mainly of connective tissues such as cartilage, tendon, ligaments, skeletal muscle, and skeletal bone. These tissues support the structure of the body, hold and protect the organs, and are responsible of movement. Since it is subjected to continuous strain, the musculoskeletal system is prone to injury by excessive loading forces or aging, whereas currently available treatments are usually invasive and not always effective. Most of the musculoskeletal injuries require surgical intervention facing a limited post-surgery tissue regeneration, especially for widespread lesions. Therefore, many tissue engineering approaches have been developed tackling musculoskeletal tissue regeneration. Materials are designed to meet the chemical and mechanical requirements of the native tissue three-dimensional (3D) environment, thus facilitating implant integration while providing a good reabsorption rate. With biological systems operating at the nanoscale, nanoengineered materials have been developed to support and promote regeneration at the interprotein communication level. Such materials call for a great precision and architectural control in the production process fostering the development of new fabrication techniques. In this mini review, we would like to summarize the most recent advances in 3D nanoengineered biomaterials for musculoskeletal tissue regeneration, with especial emphasis on the different techniques used to produce them. PMID- 30294598 TI - Genome Editing Reveals Idiosyncrasy of CNGA2 Ion Channel-Directed Antibody Immunoreactivity Toward Oxytocin. AB - Presynaptic cGMP-gated ion (CNG) channels positively or negatively modulate neurotransmitter secretion as well as the strength of synaptic transmission. Zebrafish cGMP-gated ion channel, CNGA2a (a.k.a. CNGA5), was previously reported to be specifically enriched in synaptic terminals of zebrafish oxytocin (OXT) neurons. This conclusion was based on immunoreactivity of a monoclonal antibody (mAb) clone L55/54, which was directed against the carboxy terminal tail of the CNGA2a. To study the role of CNGA2a in oxytocin neurons function, we generated zebrafish mutants of cnga2a, cnga2b and oxt genes using clustered regularly interspaced short palindromic repeats (CRISPR)-mediated genome editing. We show that mAb L55/54 specifically recognizes CNGA2a protein when expressed in heterologous cell culture system. Surprisingly, anti-CNGA2a immunoreactivity was not eliminated following knockout of either cnga2a, cnga2b or both. However, knockout of oxt resulted in total loss of anti-CNGA2a mAb immunoreactivity despite the lack of sequence and structural similarities between OXT and CNGA2a proteins. Our results provide a noteworthy lesson of differences in antibody immunoreactivity, which could only be revealed using specific genetic tools. PMID- 30294599 TI - What Is Health Information Quality? Ethical Dimension and Perception by Users. AB - Introduction: The popularity of seeking health information online makes information quality (IQ) a public health issue. The present study aims at building a theoretical framework of health information quality (HIQ) that can be applied to websites and defines which IQ criteria are important for a website to be trustworthy and meet users' expectations. Methods: We have identified a list of HIQ criteria from existing tools and assessment criteria and elaborated them into a questionnaire that was promoted via social media and mainly the University. Responses (329) were used to rank the different criteria for their importance in trusting a website and to identify patterns of criteria using hierarchical cluster analysis. Results: HIQ criteria were organized in five dimensions based on previous theoretical frameworks as well as on how they cluster together in the questionnaire response. We could identify a top-ranking dimension (scientific completeness) that describes what the user is expecting to know from the websites (in particular: description of symptoms, treatments, side effects). Cluster analysis also identified a number of criteria borrowed from existing tools for assessing HIQ that could be subsumed to a broad "ethical" dimension (such as conflict of interests, privacy, advertising policies) that were, in general, ranked of low importance by the participants. Subgroup analysis revealed significant differences in the importance assigned to the various criteria based on gender, language and whether or not of biomedical educational background. Conclusions: We identified criteria of HIQ and organized them in dimensions. We observed that ethical criteria, while regarded highly in the academic and medical environment, are not considered highly by the public. PMID- 30294600 TI - Effects of Caffeine Ingestion on Anaerobic Capacity in a Single Supramaximal Cycling Test. AB - The aim of this study was to verify the effects of caffeine on anaerobic capacity estimated by the sum of the estimated glycolytic [E[La]] and phosphagen [EPCr] metabolism based on blood lactate and excess post-oxygen consumption responses (AC[La-]+EPOCfast). Fourteen male cyclists were submitted to a graded exercise test to determine the maximal oxygen uptake ( V degrees O2max ) and intensity associated with V degrees O2max (i V degrees O2max ). Subsequently, the participants performed two supramaximal efforts at 115% of i V degrees O2max to determine the AC[La-]+EPOCfast, after previous supplementation with caffeine (6 mg.kg-1) or a placebo (dextrose), in a cross over, randomized, double blind, and placebo-controlled design. The time to exhaustion was higher in the caffeine (186.6 +/- 29.8 s) than in the placebo condition (173.3 +/- 25.3 s) (p = 0.006) and a significant correlation was found between them (r = 0.86; P = 0.00008). Significant differences were not found between AC[La-]+EPOCfast values from the placebo (4.06 +/- 0.83 L and 55.2 +/- 5.7 mL.kg-1) and caffeine condition (4.00 +/- 0.76 L and 54.6 +/- 5.4 mL.kg-1); however, a significant correlation was observed only for AC[La-]+EPOCfast expressed in absolute values (r = 0.74; p < 0.002). The E[La] and EPCr also presented no significant differences and they were significantly correlated (r = 0.82 and r = 0.55, respectively; p < 0.05). We conclude based on the overall comparison of mean values between two treatments that acute caffeine ingestion improves the time to exhaustion but does not affect anaerobic capacity estimation. PMID- 30294597 TI - Genetic Models of Leukemia in Zebrafish. AB - The zebrafish animal model is gaining increasing popularity as a tool for studying human disease. Over the past 15 years, many models of leukemia and other hematological malignancies have been developed in the zebrafish. These confer some significant advantages over similar models in other animals and systems, representing a powerful resource for investigation of the molecular basis of human leukemia. This review discusses the various zebrafish models of lymphoid and myeloid leukemia available, the major discoveries that have been made possible by them, and opportunities for future exploration. PMID- 30294601 TI - Descending Perineum Associated With Pelvic Organ Prolapse Treated by Sacral Colpoperineopexy and Retrorectal Mesh Fixation: Preliminary Results. AB - Introduction and hypothesis: Descending Perineum Syndrome (DPS) is a coloproctologic disease and the best treatment for it is yet to be defined. DPS is frequently associated with pelvic organ prolapse (POP) and it is reasonable to postulate, that treatment of POP will also have an impact on DPS. We aimed to evaluate the subjective satisfaction and improvement of DPS for patients who have undergone a sacral colpoperineopexy associated with retrorectal mesh for concomitant POP. Methods: This retrospective cohort study, conducted between February 2010 and May 2016 included all women who had undergone surgery to treat POP and DPS. Improvement of POP was assessed clinically and subjective satisfaction was assessed with a survey. Results: Among the 37 operated patients, 31 responded to the questionnaire and 77.4% were satisfied with this surgical procedure. 94.6% were objectively cured for POP. There was a 60% improvement rate for constipation, 63.5 and 68% were cured or improved for ODS and the need for digital maneuvers respectively. Conclusion: Sacral colpoperineopexy associated with retrorectal dorsal mesh appears to objectively and subjectively improve POP associated with DPS.

PMID- 30294603 TI - Microbiome and Blood Analyte Differences Point to Community and Metabolic Signatures in Lean and Obese Horses. AB - Due to modern management practices and the availability of energy dense feeds, obesity is a serious and increasingly common health problem for horses. Equine obesity is linked to insulin resistance and exacerbation of inflammatory issues such as osteoarthritis and laminitis. While the gut microbiome is thought to play a part in metabolic status in horses, bacterial communities associated with obesity have yet to be described. Here we report differences in metabolic factors in the blood of obese, normal and lean horses correlated with differences in gut microbiome composition. We report that obese horses had higher levels of leptin, triglycerides, glucose, and cortisol in their blood, and more diverse gut microbiome communities with higher relative abundance of Firmicutes, and lower numbers of Bacteroidetes and Actinobacteria. Network analyses of correlations between body condition, blood analytes, and microbial composition at the genus level revealed a more nuanced picture of microbe-host interactions, pointing to specific bacterial species and assemblages that may be signatures of obesity and leanness in the horse gut. In particular, bacteria groups positively associated with two blood analytes and obesity included Butyrivibrio spp., Prevotellaceae, Blautia spp., two members of Erysipelotrichaceae, and a Lachnospiraceae taxa. These results are an important first step in unraveling the metabolic differences between obese and lean horse gut communities, and designing targeted strategies for microbial intervention. PMID- 30294604 TI - Defensive medicine: It is time to finally slow down an epidemic. AB - Defensive medicine is widespread and practiced the world over, with serious consequences for patients, doctors, and healthcare costs. Even students and residents are exposed to defensive medicine practices and taught to take malpractice liability into consideration when making clinical decisions. Defensive medicine is generally thought to stem from physicians' perception that they can easily be sued by patients or their relatives who seek compensation for presumed medical errors. However, in our view the growth of defensive medicine should be seen in the context of larger changes in the conception of medicine that have taken place in the last few decades, undermining the patient-physician trust, which has traditionally been the main source of professional satisfaction for physicians. These changes include the following: time directly spent with patients has been overtaken by time devoted to electronic health records and desk work; family doctors have played a progressively less central role; clinical reasoning is being replaced by guidelines and algorithms; the public at large and a number of young physicians tend to believe that medicine is a perfect science rather than an imperfect art, as it continues to be; and modern societies do not tolerate the inevitable morbidity and mortality. To finally reduce the increasing defensive behavior of doctors around the world, the decriminalization of medical errors and the assurance that they can be dealt with in civil courts or by medical organizations in all countries could help but it would not suffice. Physicians and surgeons should be allowed to spend the time they need with their patients and should give clinical reasoning the importance it deserves. The institutions should support the doctors who have experienced adverse patient events, and the media should stop reporting with excessive evidence presumed medical errors and subject physicians to "public trials" before they are eventually judged in court. PMID- 30294605 TI - Web-based learning in inflammatory bowel diseases: General truths and current specifics. AB - In a field rapidly evolving over the past few years, the management of inflammatory bowel diseases (IBD), Crohn's disease and ulcerative colitis, is becoming increasingly complex, demanding and challenging. In the recent years, IBD quality measures aiming to improve patients' care have been developed, multiple new medical therapies have been approved, new treatment goals have been set with the "treat-to-target" concept and drug monitoring has been implemented into IBD clinical management. Moreover, patients are increasingly using Internet resources to obtain information about their health conditions. The healthcare professional with an interest in treating IBD patients should deal with all these challenges in everyday practice by establishing, enhancing and maintaining a strong core of knowledge and skills related to IBD. This is an ongoing process and traditionally these needs are covered with additional reading of textbook or journal articles, attendance at meetings or conferences, or at local rounds. Web based learning resources expand the options for knowledge acquisition and save time and costs as well. In the new era of communications technology, web-based resources can cover the educational needs of both patients and healthcare professionals and can contribute to improvement of disease management and patient care. Healthcare professionals can individually visit and navigate regularly relevant websites and tailor choices for educational activities according to their existing needs. They can also provide their patients with a few certified suitable internet resources. In this review, we explored the Internet using PubMed and Startpage (Google), for web-based IBD-related educational resources aiming to provide a guide for those interested in obtaining certified knowledge in this subject. PMID- 30294606 TI - Dual HER2 inhibition strategies in the management of treatment-refractory metastatic colorectal cancer: History and status. AB - Human epidermal growth factor receptor 2 (HER2) signaling pathway activation has been identified as a contributor to de novo or acquired resistance to epidermal growth factor receptor (EGFR) inhibitors in a small subset of patients with metastatic colorectal cancer (mCRC). Dual anti-HER2-targeted treatment exhibits strong antitumor activity in preclinical models of HER2-positive mCRC, supporting its testing in clinical trials. The HERACLES trial at four Italian academic cancer centers has confirmed the effectiveness of dual blockage of HER2 with trastuzumab plus lapatinib in patients with heavily pretreated HER2-positive mCRC, refractory to the anti-EGFR antibodies cetuximab or panitumumab. Here, we reviewed the preclinical studies exploring the role of HER2 signaling in the development of anti-EGFR therapy resistance and discussed the status of clinical trials assessing the activity of HER2 inhibitors in this setting. PMID- 30294607 TI - Isolation and characterization of a new candidate human inactivated rotavirus vaccine strain from hospitalized children in Yunnan, China: 2010-2013. AB - AIM: To determine the distribution of rotavirus VP7 gene in hospitalized children in Yunnan, China. METHODS: A total of 366 stool specimens were collected from hospitalized children in hospitals in Yunnan Province from September 2010 to December 2013. The genomic RNA electropherotypes and the G genotypes of the rotaviruses were determined. A phylogenetic analysis of the VP7 gene was performed. Rotavirus isolation was performed, and characterized by plaque, minimum essential medium, and all genes sequence analysis. Quantification of antibodies for inactivated vaccine prepared with ZTR-68 was examined by enzyme linked immunosorbent assay and microneutralization assay. RESULTS: Group A human rotavirus was detected in 177 of 366 (48.4%) stool samples using a colloidal gold device assay. The temporal distribution of rotavirus cases showed significant correlation with the mean air temperature. Rotaviruses were isolated from 13% of the rotavirus-positive samples. The predominant genotype was G1 (43.5%), followed by G3 (21.7%), G9 (17.4%), G2 (4.3%), G4 (8.7%), and mixed (4.3%) among a total of 23 rotavirus isolates. A rotavirus strain was isolated from a rotavirus positive stool sample of a 4-month-old child in The First People's Hospital of Zhaotong (2010) for use as a candidate human inactivated rotavirus vaccine strain and for further research, and was designated ZTR-68. The genotype of 11 gene segments of strain ZTR-68 (RVA/Human-wt/CHN/ZTR-68/2010/G1P[8]) was characterized. The genotype constellation of strain ZTR-68 was identified as G1 P[8]-I1-R1-C1-M1-A1-N1-T1-E1-H1. The VP7 and VP4 genotypes of strain ZTR-68 were similar to Wa-like strains.CONCLUSIONSA high prevalence of the G1, G2, and G3 genotypes was detected from 2010 to 2012. However, a dominant prevalence of the G9 genotype was identified as the cause of gastroenteritis in children in Yunnan, China, in 2013. A candidate human inactivated rotavirus vaccine strain, designated ZTR-68 was isolated, characterized, and showed immunogenicity. Our data will be useful for the future formulation and development of a vaccine in China. PMID- 30294608 TI - Diagnostic value of elevated serum carbohydrate antigen 199 level in acute cholangitis secondary to choledocholithiasis. AB - AIM: To investigate the diagnostic value of abnormal serum carbohydrate antigen 199 (CA199) level in acute cholangitis secondary to choledocholithiasis. METHODS: In this retrospective cohort study, the clinical data of 727 patients with choledocholithiasis admitted to the Third Affiliated Hospital of Zunyi Medical College from June 2011 to June 2017 were collected. Among these patients, 258 patients had secondary acute cholangitis and served as observation group, and the remaining 569 choledocholithiasis patients served as the control group. Serum liver function indexes and tumor markers were detected in both groups, and the receiver operating characteristic (ROC) curves were constructed for markers showing statistical significances. The cutoff value, sensitivity, and specificity of each marker were calculated according to the ROC curves. RESULTS: The results of liver function tests showed no significant differences between the two groups (P > 0.05). Tumor markers including serum CA125, CA153, carcinoembryonic antigen, and alpha fetoprotein levels were also not significantly different (P > 0.05); however, the serum CA199 level was significantly higher in the observation group than in the control group (P < 0.05). The ROC curve analysis showed that the area under the curve was 0.885 (95%CI: 0.841-0.929) for CA199, and the cutoff value of 52.5 kU/L had the highest diagnostic accuracy, with a sensitivity of 86.8% and a specificity of 81.6%. CONCLUSION: Abnormally elevated serum CA199 level has an important value in the diagnosis of acute cholangitis secondary to choledocholithiasis. It may be a specific inflammatory marker for acute cholangitis. PMID- 30294610 TI - Neurofibroma discharged from the anus with stool: A case report and review of literature. AB - Isolated neurofibromas that affect the gastrointestinal tract are rare and almost always manifest as neurofibromatosis type 1 or multiple endocrine neoplasia type 2b. In this paper, we present a case of a 24-year-old female with abdominal pain who discharged a neurofibroma in her stool without any blood on it. A colonoscopy showed multiple small polyps in the sigmoid colon and a nodule in the ileocecus. The pathology results and the immunohistochemical stains of the removed neoplasm from the ileocecus confirmed the diagnosis was a bowel neurofibroma. We report a rare case of ileocecal neurofibroma due to the patient's affected gastrointestinal tract, without any associated systemic syndrome other than a neurofibroma discharged in the stool. PMID- 30294609 TI - Balo's concentric sclerosis in a patient with spontaneous remission based on magnetic resonance imaging: A case report and review of literature. AB - Balo's concentric sclerosis (BCS) is a rare monophasic demyelinating disease known as multiple sclerosis subtype and seen as a round lesion with variable hyper and hypo-detoxification layers. Characteristic appearance can be seen as "bulb eye" or "onion bulb". The initial terminology for this neurological disorder was leukoencephalitis periaxialis concentrica; this is defined as a disease in which the white matter of the brain is destroyed in concentric layers in such a way as to leave the axial cylinders intact. This report presents a case of BCS with spontaneous healing of the patient and a mass lesion with concentric rings adjacent to the left lateral ventricle and the posterior portion of the corpus callosum with peripheral vasogenic edema. The neurological lesion of the patient was similar to the magnetic resonance imaging and clinical findings of the BCS. PMID- 30294611 TI - Balloon dilator controls massive bleeding during endoscopic ultrasound-guided drainage for pancreatic pseudocyst: A case report and review of literature. AB - Pancreatic pseudocyst (PPC), a common sequela of acute or chronic pancreatitis, was defined by the revised Atlanta classification as "a collection." Endoscopic ultrasound (EUS)-guided drainage is often considered a standard first-line therapy for patients with symptomatic PPC. This effective approach exhibits 90% 100% technical success and 85%-98% clinical success. Bleeding is a deadly adverse event associated with EUS-guided drainage procedures, and the bleeding rate ranges from 3% to 14%. Hemostasis involves conservative treatment, endoscopy, interventional radiology-guided embolization and surgery. However, few studies have reported on EUS-guided drainage with massive, multiple hemorrhages related to severe pancreatogenic portal hypertension (PPH). Thus, the aim of this case report was to present a case using a balloon dilator to achieve successful hemostasis for PPH-related massive bleeding in EUS-guided drainage of PPC. To our knowledge, this method has not been previously reported. PMID- 30294612 TI - Twin pregnancy with triple parathyroid adenoma: A case report and review of literature. AB - Primary hyperparathyroidism (PHPT) is rare during pregnancy. A case of twin pregnancy with three simultaneous parathyroid adenomas at the same time has not been reported. Multiple parathyroid lesions are difficult to diagnose, as pregnant women who insist upon continuing a pregnancy are not able to undergo 99mTc-sestamibi scintigraphy, so cases of PHPT are easily unobserved and often can have serious consequences for the patient and the fetus. Therefore, we reported a case of a 28-year-old woman mid-pregnancy with twins, who had hypercalcemia and was eventually diagnosed with twin pregnancy with PHPT due to a triple parathyroid adenoma, had good pregnancy outcomes after undergoing surgery in mid-pregnancy. Twin pregnancy with PHPT due to a triple parathyroid adenoma, as presented in this case, is very rare and surgery in mid-pregnancy is demonstrated here as safe. Intraoperative parathormone monitoring was and remains key to a successful operation. PMID- 30294613 TI - Unusual cause of lesions in the descending duodenum and liver: A case report and review of literature. AB - The descending duodenum is rarely involved in Schistosoma japonicum (S. japonicum) infection. Here, we report a case of acute Schistosoma infection, which presented with abdominal pain, abdominal distension and irregular fever. Tumor-like lesions were observed in the descending duodenum. Simultaneously, heterogeneity in hepatic perfusion was demonstrated by dynamic computed tomography scanning. Biopsy of the descending duodenum showed the deposition of Schistosoma eggs. Following administration of the antihelminthic drug praziquantel, the patient showed rapid clinical improvement.

Myeloid sarcoma is classified into two types based on whether onset of the disease is complicated by haematologic diseases: extramedullary infiltration of leukaemia (leukaemic MS) and isolated myeloid sarcoma. The incidence of isolated myeloid sarcoma is low. In particular, isolated myeloid sarcoma involving the pancreas is extremely rare and prone to misdiagnosis. This case report describes the long and eventful diagnostic process of a case of myeloid sarcoma involving the pancreas and orbit. Due to a lack of typical clinical manifestations and imaging characteristics, the patient underwent several rounds of treatment without a confirmed diagnosis. Eventually, the final diagnosis was pathologically confirmed using several types of biopsies and immunohistochemical detection. To date, this type of disease has not been reported in the literature. This case report describes the detailed diagnostic process and discusses the strategies used for diagnosis, which will facilitate the diagnosis of such diseases in the future.

PMID- 30294618 TI - Validation of an Immunoassay for Anti-thymidine Phosphorylase Antibodies in Patients with MNGIE Treated with Enzyme Replacement Therapy. AB - Erythrocyte encapsulated thymidine phosphorylase is recombinant Escherichia coli thymidine phosphorylase encapsulated within human autologous erythrocytes and is under development as an enzyme replacement therapy for the ultra-rare inherited metabolic disorder mitochondrial neurogastrointestinal encephalomyopathy. This study describes the method validation of a two-step bridging electrochemiluminescence immunoassay for the detection of anti-thymidine phosphorylase antibodies in human serum according to current industry practice and regulatory guidelines. The analytical method was assessed for screening cut point, specificity, selectivity, precision, prozone effect, drug tolerance, and stability. Key findings were a correction factor of 129 relative light units for the cut-point determination; a specificity cut point of 93% inhibition; confirmed intra-assay and inter-assay precision; assay sensitivity of 356 ng/mL; no matrix or prozone effects up to 25,900 ng/mL; a drug tolerance of 156 ng/mL; and stability at room temperature for 24 hr and up to five freeze-thaws. Immunogenicity evaluations of serum from three patients who received erythrocyte encapsulated thymidine phosphorylase under a compassionate treatment program showed specific anti-thymidine phosphorylase antibodies in one patient. To conclude, a sensitive, specific, and selective immunoassay has been validated for the measurement of anti-thymidine phosphorylase antibodies; this will be utilized in a phase II pivotal clinical trial of erythrocyte encapsulated thymidine phosphorylase. PMID- 30294616 TI - Multihospital Outbreak of a Middle East Respiratory Syndrome Coronavirus Deletion Variant, Jordan: A Molecular, Serologic, and Epidemiologic Investigation. AB - Background: An outbreak of Middle East respiratory syndrome coronavirus (MERS CoV) in Jordan in 2015 involved a variant virus that acquired distinctive deletions in the accessory open reading frames. We conducted a molecular and seroepidemiologic investigation to describe the deletion variant's transmission patterns and epidemiology. Methods: We reviewed epidemiologic and medical chart data and analyzed viral genome sequences from respiratory specimens of MERS-CoV cases. In early 2016, sera and standardized interviews were obtained from MERS CoV cases and their contacts. Sera were evaluated by nucleocapsid and spike protein enzyme immunoassays and microneutralization. Results: Among 16 cases, 11 (69%) had health care exposure and 5 (31%) were relatives of a known case; 13 (81%) were symptomatic, and 7 (44%) died. Genome sequencing of MERS-CoV from 13 cases revealed 3 transmissible deletions associated with clinical illness during the outbreak. Deletion variant sequences were epidemiologically clustered and linked to a common transmission chain. Interviews and sera were collected from 2 surviving cases, 23 household contacts, and 278 health care contacts; 1 (50%) case, 2 (9%) household contacts, and 3 (1%) health care contacts tested seropositive. Conclusions: The MERS-CoV deletion variants retained human-to-human transmissibility and caused clinical illness in infected persons despite accumulated mutations. Serology suggested limited transmission beyond that detected during the initial outbreak investigation. PMID- 30294619 TI - Generation of Human Mesenchymal Stem Cell 3D Spheroids Using Low-binding Plates. AB - The 3D culture of human mesenchymal stem cells (hMSCs) represents a more physiological environment than classical 2D culture and has been used to enhance the MSC secretome or extend cell survival after transplantation. Here we describe a simple and affordable method to generate 3D spheroids of hMSCs by seeding them at high density in a low-binding 96-well plate. Spheroids of hMSCs cultured in low-binding 96-well plates can be used to study the basic biology of the cells and to generate conditioned media or spheroids to be used in transplantation therapeutic approaches. These MSCs or their secretome can be used as a regenerative therapy and for tissue repair across multiple disease areas, including neurodegeneration. In comparison to other methods (hanging drop, use of gels or biomaterials, magnetic levitation, etc.), the method described here is simple and affordable with no need to use specialized equipment, expensive materials or complex reagents. PMID- 30294620 TI - Hilly or mountainous surface: a new CT feature to predict the behavior of pure ground glass nodules? AB - Persistent pure ground-glass nodules (pGGNs) typically show an indolent course with very slow growth rates. These slow-growing lesions exhibit different growth patterns regardless of their initial computed tomography (CT) features. Therefore, predicting the aggressive behavior of pGGNs on initial CT remains a diagnostic challenge. The literature reports that computerized analysis and various quantitative features have been tested to improve the risk stratification for pGGNs. The present article describes the long-term follow-up of two pGGNs with different behavior and introduces, for the first time, a new computerized method of analysis that could be helpful for predicting the future behavior of pGGNs.

AB - Natural gas is a kind of fuel that is used in various heating systems for combustion processes. Combustion of natural gas produce such air pollutants as CO2, NOx, SOx, PM, CO, and HC. During cold days, total gas consumption in Iran goes up. Thus, in these days it is likely to make some changes in gas properties that can affect the emissions from gas heaters. Portable flue gas analyzer (LANCOM III) was used for, SO2, NOX, and CXHY measurement from December 2012 to April 2013. Data show that emissions of pollutants from the gas heater were different during the cold seasons. On colder days, total gas consumption in the country increased, SO2 emerged in heater stack, and the concentration of hydrocarbons (CXHY) significantly increased as well. This emergence could be attributed to the changes in gas properties in the colder days. In these days, the transient flow and high changes of speed and pressure in the gas pipes could lead to release of some deposited sulfur in gas flow. Therefore, sulfur dioxide will be generated in the combustion process.

AB - The application of sewage sludge to agricultural soil induces co-exposure of prokaryotic populations to antibiotics and heavy metals, thus exerting a selection pressure that may lead to the development of antibiotic resistance. Here, soil samples from a long-term factorial field experiment in which sewage sludge was applied to agricultural soil, at different rates (40 and 80 t ha-1) and frequencies (every 1, 2 and 4 years) of application, were studied to assess: (i) the effect of sewage sludge application on prokaryotic community composition, (ii) the links between prokaryotic community composition and antibiotic resistance profiles, and (iii) the links between antibiotic resistance and metal(oid) concentrations in amended soil. We found no significant impact of sewage sludge on prokaryotic community composition. Some antibiotic resistance genes (ARGs) correlated positively with particular prokaryotic taxa, being Gemmatimonadetes the taxon with the greatest number of positive correlations at phylum level. No positive correlation was found between prokaryotic taxa and genes encoding resistance to sulfonamides and FCA. All metal(oid)s showed positive correlations with, at least, one ARG. Metal(oid) concentrations in soil also showed positive correlations with mobile genetic element genes, particularly with the gene tnpA-07. These data provide useful information on the links between soil prokaryotic composition and resistome profiles, and between antibiotic resistance and metal(oid) concentrations, in agricultural soils amended with sewage sludge.

PMID- 30294630 TI - Dataset on non-carcinogenic risk via nitrate and nitrite in the groundwater of Divandarreh County, Kurdistan province, Iran: A potential concern for drinking. AB - The presence of elevated nitrate (NO3-) and nitrite (NO2-) concentration in drinking water higher than the standard limits could endanger the health of consumers. For this data article, concentration of NO3- and NO2- was measured in 118 samples collected from 59 active rural wells in Divandarreh County and the non-carcinogenic risk in the adults and children was estimated by Monte Carlo simulation (MCS). The obtained data showed that the average concentration of NO3- and NO2- was ranges from 31.37 +/- 18.87 mg/L and 1.45 +/- 0.90 mg/L respectively. Based on acquired data, NO3- concentrations were 37 times higher than NO2- with significant p value of < 0.05. The average concentration of NO3- and NO2- was lower than the national standard with p value < 0.05. However, the concentration of NO3- and NO2- in 23.7% and 13.5% of wells was higher than the national standard of Iran. Total target hazard quotient (TTHQ) in the adults and children was 1.78 and 1.54, respectively. Although, the average concentration of NO3- and NO2- in drinking water was lower than the national standard limits, but the non-carcinogenic risk assessment showed that the children and adults are at a significant risk via nitrate and nitrite in the rural Divandarreh County (TTHQ > 1).

PMID- 30294633 TI - Data on fluoride contamination in potable water in alluvial plains of district Panipat, Haryana, India. AB - This data set reveals the fluoride concentration level of an alluvial aquifer of Panipat district Haryana India. The whole district of Panipat relies on groundwater for its agricultural, industrial and domestic purposes. Fluoride concentration in the study area varied from 0.5 mg/L to 5.95 mg/L with an average of 1.6 mg/L. 42.9% of the groundwater samples have shown higher fluoride concentration in groundwater than the permissible level prescribed by World Health Organisation and Bureau of Indian Standards. The spatial distribution map of fluoride has interestingly shown contrast between western and eastern parts of the region. Higher fluoride concentration (1.00-5.95 mg/L) in groundwater is witnessed in western half whereas the eastern half had comparatively lower concentration of fluoride ranging from 0.5 mg/L to 3.0 mg/L with maximum area having concentrations up to 1.5 mg/L. Major part 52.23% of Panipat district has shown high fluoride concentration in groundwater than the permissible level. It is further suggested that prolonged intake of groundwater with fluoride concentration higher than the permissible levels may cause dental or skeletal fluorosis in the locals.

AB - Empirically based, the data description covers business transparency in Russia and availability of corporate information for interested parties. Entry barriers in the form of a fee for hard copies of documents are perceptible as an important indicator of business publicity. The study made it possible to summarize current data on 5070 Russian enterprises in order to estimate document copying cost differentiation according to the developed model. The sample size made it also possible to ensure high levels of data quality and representativeness. Actual limiting average mean error Deltap was 3.47% with 99% of study validity. The analysis relied on regional and sectorial data groupings to show a strength of various impact factors. In view of this, correlation coefficients, average and weighted average cost values, and descriptive statistics became secondary indicators. The cost value distributed along an interval scale is a major empirical result of the research. The examination of the obtained data makes it possible to identify an availability level of corporate information for various stakeholders and the general public. This is a part of civil right enforcement in the field of information control and validity check. Conjugated scientific issues include pricing of non-core services of companies, corporate relations and modelling of market behaviours. By making a representative data set, authors make an effort to fill the fact-based gap available in other disciplines and related to business transparency in Russia.

AB - By far most macromolecular crystallographic data collection and experimental phasing is nowadays carried out using synchrotron radiation. Here, we present two crystallographic datasets collected on a home-source X-ray diffractometer, which can per se be use to experimentally solve the atomic-resolution crystal structure of the Src homology 3(SH3)-like domain from the postsynaptic protein Shank3. The refined structure was described in the article "Structure of an unconventional SH3 domain from the postsynaptic density protein Shank3 at ultrahigh resolution" (Ponna et al., 2017) [1]. Crystals of the Shank3 SH3 domain were derivatized through soaking in 1 M sodium iodide prior to diffraction data collection at a wavelength of 1.54 A. High-resolution data are reported for a native crystal to 1.01 A and an iodide-derivatized one to 1.60 A. The crystals suffered from several anomalies affecting experimental phasing: a high fraction (34-40%) of pseudomerohedral twinning, significant pseudotranslational symmetry (> 15%) with the operator 0.5,0,0.5, and a low solvent content. Twinning with the operator h, k,-l is made possible by the space group P21 coupled with a unit cell beta angle of 90.0 degrees . The data can be used to repeat and optimize derivatization and phasing procedures, to understand halide interactions with protein surfaces, to promote the use of home X-ray sources for protein structure determination, as well as for educational purposes and protocol development.

AB - Present deadest collection was aimed to evaluate the efficiency of raw pumice (RWP) and Mn-modified pumice (MMP). Response surface methodology (RSM) based on the central composite designs (CCD) was applied to evaluate the effects of independent variables including pH, adsorbents dosage, contact time and adsorbate concentration on the response function and the best response values were predicted. The Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the adsorbents. Based on acquired data, the maximum efficiency removal of phenol was obtained 89.14% and 100% for raw and Mn-modified pumice respectively. The obtained data showed pH was effective parameter on phenol removal among the different variables. Evaluation of data using isotherms and kinetics models showed the fitted with Langmuir isotherm and pseudo second order kinetic for both adsorbents. According to obtained data was observed that modification of pumice can improve the efficiency removal of phenol to meet the effluent standards.

AB - The present data article was prepared with the aim of assessing the instructor's professional ethics of teaching in Kermanshah Medical Science University from the student's perspective in 2017. For this data article, 260 students in Kermanshah University of Medical Sciences (KUMS) were selected by a simple random sampling method. The data collection tool was based on "Ethical principles for college and university teaching" (Murray et al., 1996), teaching professional ethics questionnaire. The obtained data showed that the teachers have an average of (3.74 +/- 0.73) in terms of personality characteristic, (3.48 +/- 0.75) for dominating on content, (3.64 +/- 0.64) in terms of dominating on teaching practices, (3.65 +/- 0.63) for understanding the different learner's aspects, (3.65 +/- 0.71) in terms of teaching assessment and 4.41 +/- 0.78 for observing the educational regulations. These evaluated data were higher than the average level. The acquired data have shown that the instructors teaching professional ethic were higher than the average level, but still it was not ideal. Therefore, preparing and editing the teaching professional ethics charter and putting it in educational content during the teacher's service are suggested for the promotion of this status.

AB - Micronutrients include electrolytes, minerals, vitamins, and carotenoids, and are required in microgram or milligram quantities for cellular metabolism. The liver plays an important role in micronutrient metabolism and this metabolism often is altered in chronic liver diseases. Here, we review how the liver contributes to micronutrient metabolism; how impaired micronutrient metabolism may be involved in the pathogenesis of nonalcoholic fatty liver disease (NAFLD), a systemic disorder of energy, glucose, and lipid homeostasis; and how insights gained from micronutrient biology have informed NAFLD therapeutics. Finally, we highlight some of the challenges and opportunities that remain with investigating the contribution of micronutrients to NAFLD pathology and suggest strategies to incorporate our understanding into the care of NAFLD patients.

AB - The purpose of the article is to compare different indicators of social position as measures of social inequality in health in a population sample from an indigenous arctic people, the Inuit in Greenland. Data was collected during 2005 2015 and consisted of information from 3967 adult Inuit from towns and villages in all parts of Greenland. Social inequalities for smoking and central obesity were analysed in relation to seven indicators of social disparity in four dimensions, i.e. education and employment, economic status, sociocultural position, and place of residence. For each indicator we calculated age-adjusted prevalence by social group, rate ratio and the concentration index. The indicators were correlated with Pearson's r ranging from 0.24 to 0.82. Concentration indices ranged from 0.01 to 0.17. We could not conclude that one indicator was superior to others. Most of the indicators were traditional socioeconomic indicators used extensively in research in western countries and these seemed to be useful among the Inuit too, in particular household assets and job. Two sociocultural indicators developed for use among the Inuit and which included parameters specific to the indigenous peoples in the transition from a traditional to a modern life style proved to be equally useful but not superior to the traditional socioeconomic indicators. The choice of indicator must depend on what it is realistic to collect in the actual research setting and the use of more than one indicator is recommended. It is suggested to further develop culture specific indicators of social position for indigenous peoples. PMID- 30294658 TI - Interlaboratory validation of cerebrospinal fluid alpha-synuclein quantification in the diagnosis of sporadic Creutzfeldt-Jakob disease. AB - Introduction: Cerebrospinal fluid alpha-synuclein level is increased in sporadic Creutzfeldt-Jakob disease cases. However, the clinical value of this biomarker remains to be established. In this study, we have addressed the clinical validation parameters and the interlaboratory reproducibility by using an electrochemiluminescent assay. Methods: Cerebrospinal fluid alpha-synuclein was quantified in a total of 188 sporadic Creutzfeldt-Jakob disease and non Creutzfeldt-Jakob-disease cases to determine sensitivity and specificity values and lot-to-lot variability. Two round robin tests with 70 additional cases were performed in six independent laboratories. Results: A sensitivity of 93% and a specificity of 96% were achieved in discriminating sporadic Creutzfeldt-Jakob disease. No differences were detected between lots. The mean interlaboratory coefficient of variation was 23%, and the intralaboratory coefficient of variations ranged 2.70%-11.39%. Overall, 97% of samples were correctly diagnosed. Discussion: The herein validated alpha-synuclein assay is robust, accurate, and reproducible in identifying Creutzfeldt-Jakob disease cases. Thus, it is ready for implementation in the clinical practice to support the diagnosis of Creutzfeldt-Jakob disease. PMID- 30294659 TI - Network-based assessment of collaborative research in neuroscience. AB - Introduction: The purpose of this study was to describe collaborative research in neuroscience within the context of the Center for Neurodegeneration and Translational Neuroscience (CNTN), a Center of Biomedical Research Excellence supported by the National Institute of General Medical Science. Drawing upon research on the science of team science, this study investigated the way that interactions around research emerged over the course of establishing a new research center. The objectives were to document changes in research activity and describe how human research support infrastructure functioned to support the production of science. Methods: Social network analyses were used to model coauthorship relationships based on publication histories from baseline (2014) through the current grant year (2017) for key personnel (n = 12), as well as survey data on collaborative engagement among CNTN members (n = 59). Results: Exponential random graph models indicated that over time, CNTN members were increasingly likely to form coauthorship relationships. Community detection algorithms and brokerage analyses suggested that the CNTN was functioning as intended to support scientific development. Discussion: Assessment of team science efforts is critical to evaluating and developing appropriate support structures that facilitate successful team science efforts in translational neuroscience. PMID- 30294660 TI - Genetic associations of bradykinin type 2 receptor, alpha-adrenoceptors and endothelial nitric oxide synthase with blood pressure and left ventricular mass in outpatients without overt heart disease. AB - Background: Physiological pathways such as bradykinin, renin-angiotensin, neurohormones and nitric oxide have been shown to play an important role in the regulation of cardiovascular function. Genetic variants of these pathways may impact blood pressure and left ventricular (LV) mass in different populations. To evaluate associations of genetic polymorphisms of bradykinin B2 receptor (BDKRB2), alpha-adrenergic receptors (ADRA) and endothelial nitric oxide synthase (eNOS) on the modulation of the blood pressure and the left ventricular mass. Methods: We enrolled 758 individuals without overt heart disease. Blood pressure was estimated by auscultatory method during the clinical examination. Left ventricular (LV) mass was assessed by echocardiography. Genotypes for ADRA1A rs1048101, ADRA2A rs553668, ADRA2B rs28365031, eNOS rs2070744, eNOS rs1799983, and BDKRB2 rs5810761 polymorphisms were assessed by high-resolution melting analysis. Results: BDKRB2 polymorphism rs5810761 was associated with blood pressure. Carriers of DD genotype had higher levels of SBP and DBP than carrier of II genotype (p = 0.013 and p = 0.007, respectively). eNOS polymorphism rs1799983 was associated with DBP. Carriers of GT genotype had lower levels of DBP than carriers of GG genotype (p = 0.018). eNOS polymorphism rs2070744 was associated with LV mass. Carriers of TC genotype had higher LV mass than carriers of TT genotype (p = 0.028). Conclusions: In a cohort of individuals without overt heart disease, the BDKRB2 rs5810761 polymorphism (DD genotype carriers) were associated higher systolic and diastolic blood pressures, and the eNOS rs1799983 polymorphism (T allele carriers) were associated with lower diastolic blood pressure. The eNOS rs2070744 polymorphism (C allele carriers) was associated with higher left ventricular mass. These data suggest that eNOS and bradykinin receptor genetic variants may be potential markers of common cardiovascular phenotypes. PMID- 30294661 TI - Knowledge of HIV and Intention to Engage in Risky Sexual Behaviour and Practices among Senior School Adolescents in Ibadan, Nigeria. AB - A high proportion of adolescents still engage in risky sexual behaviours that put them at risk of infection complications of risky sexual behaviours including Human Immunodeficiency Virus (HIV) infection despite the different interventions already in place. This study was designed to determine the adolescents' knowledge of HIV, intention to engage in risky sexual behaviour and sexual practices. A 3 stage sampling technique was used to select 240 adolescents in senior secondary schools in Ibadan, Nigeria. Data were obtained using a pretested, semi structured, self-administered questionnaire. Data were analysed using descriptive statistics and Chi-square test at 5% level of significance. The mean age of the respondents was 16.3+/-1.4 years and 126(52.5%) were females. Only 34.3% had good knowledge of HIV and there were misconceptions about its transmission. Most of the respondents (95.0%) had intention to engage in risky sexual behaviour and those with good knowledge of HIV were willing to engage in risky sexual behavour with familiar people. Good knowledge was associated with intention to engage in low risk sexual behaviour. Seventy-nine (32.9%) were sexually active and they had better knowledge of HIV. Knowledge of HIV was low among this study group and was not associated with their intention to engage in risky sexual behaviour. There is need for more effective and appropriate school and community-based intervention programmes which can impact positively on the adolescents' sexual behaviour. PMID- 30294662 TI - Human Papilloma Virus Vaccine Awareness and Vaccination History in Patients Attending STI Clinics in Lagos and Ibadan, Nigeria. AB - HPV is one of the most common causes of sexually transmitted disease in both men and women worldwide. It is transmitted through vaginal, anal, and oral sex. This study provided information on the Human Papilloma Virus (HPV) vaccine awareness and vaccination history in relation to the level of antibodies to (HPV) in the population at risk in Nigeria. Patients attending STI clinics at Lagos and Ibadan were recruited and informed consent was obtained from all the participants. Using semi structured questionnaire, vaccination history, demography and past experiences of the patients were obtained. Whole blood samples were obtained and the sera screened for specific antibodies to HPV using ELISA test kits for determination of IgG to HPV by DIA PRO Diagnostic Bioprobes Milano-Italy according to the manufacturer's instruction. Of the170 samples analysed 50 (29.4%) samples were positive for HPV. Thirty (17.6%) were from females and 20 (11.7%) of them were males. Thirty-five (35%) of the 100 women participants were aware of HPV vaccine. 15(15%) women did not take the vaccine because they did not know where to get it while 20 (20%) of them could not afford it. It was also noted that there is higher prevalence among the middle-aged women. A high prevalence of HPV antibodies was observed in the study yet none of the participants had received the HPV vaccine thus the antibodies may be from infection. Implication is that the 30 women who tested positive for the HPV antibodies may be at risk of cervical cancer. PMID- 30294663 TI - Synthesis and preliminary preclinical evaluation of fluorine-18 labelled isatin-4 (4-methoxyphenyl)-3-thiosemicarbazone ([18F]4FIMPTC) as a novel PET tracer of P glycoprotein expression. AB - Background: Several P-glycoprotein (P-gp) substrate tracers are available to assess P-gp function in vivo, but attempts to develop a tracer for measuring expression levels of P-gp have not been successful. Recently, (Z)-2-(5-fluoro-2 oxoindolin-3-ylidene)-N-(4-methoxyphenyl)hydrazine-carbothioamide was described as a potential selective P-gp inhibitor that is not transported by P-gp. Therefore, the purpose of this study was to radiolabel two of its analogues and to assess their potential for imaging P-gp expression using PET. Results: [18F]2 (4-fluoro-2-oxoindolin-3-ylidene)-N-(4-methoxyphenyl)hydrazine-carbothioamide ([18F]5) and [18F]2-(6-fluoro-2-oxoindolin-3-ylidene)-N-(4 methoxyphenyl)hydrazine-carbothioamide ([18F]6) were synthesized and both their biodistribution and metabolism were evaluated in rats. In addition, PET scans were acquired in rats before and after tariquidar (P-gp inhibitor) administration as well as in P-gp knockout (KO) mice.Both [18F]5 and [18F]6 were synthesized in 2-3% overall yield, and showed high brain uptake in ex vivo biodistribution studies. [18F]6 appeared to be metabolically unstable in vivo, while [18F]5 showed moderate stability with limited uptake of radiolabelled metabolites in the brain. PET studies showed that transport of [18F]5 across the blood-brain barrier was not altered by pre-treatment with the P-gp inhibitor tariquidar, and uptake was significantly lower in P-gp KO than in wild-type animals and indeed transported across the BBB or bound to P-gp in endothelial cells. Conclusion: In conclusion, [18F]5 and [18F]6 were successfully and reproducibly synthesized, albeit with low radiochemical yields. [18F]5 appears to be a radiotracer that binds to P-gp, as showed in P-gp knock-out animals, but is not a substrate for P gp. PMID- 30294664 TI - Screw theory based mathematical modeling and kinematic analysis of a novel ankle rehabilitation robot with a constrained 3-PSP mechanism topology. AB - As a common athletics injury in orthopedics clinic, ankle injury may affect a person's daily life and ankle injury rehabilitation has gained increasing interests from the medical and robotic societies. A novel hybrid ankle rehabilitation robot is proposed, which composing of a serial and a parallel part. In order to analyze its kinematic performances, the parallel part of the robot is simplified as a constrained 3-PSP parallel mechanism. A mathematical model for the parallel part of the robot is established based on the screw theory. Then the inverse kinematics is obtained, and the reciprocal twists, Jacobian matrices and the singularity of the robot are analyzed. Finally the workspace of the central point on the moving platform is predicted. The kinematic analyses manifest that the proposed hybrid rehabilitation robot not only can realize three kinds of ankle rehabilitation motions, but also can eliminate singularity with enhanced workspace. The workspace of the central point reveals that the hybrid robot can fully meet the demanded rehabilitation space by comparing with the clinic demands. Our results reveals the characteristic structure of the hybrid rehabilitation robot and its superiority, it offers some basis data for the future enhancement of the device. PMID- 30294665 TI - ParaStamp and Its Applications to Cell Patterning, Drug Synergy Screening, and Rewritable Devices for Droplet Storage. AB - Engineered materials have been employed as versatile tools to explore the fundamental cell biology/drug development as well as to approach the intelligent device, thereby becoming the key components in modern technology. Herein, a ParaStamp technique has been revealed to possess applications for cell patterning, drug screening, and rewritable functional patterning. The ParaStamp includes a micropatterned PDMS master and a liquid-phased paraffin oil generated at high temperature, which can transfer the patterned paramembrane onto varied material surfaces, such as glass, polystyrene, and flexible foil. This technique is simple and cost-effective to meet the high-throughput requirement for industries. Taken together, our findings herein should have general insights in cell biology, biodetection, and development of smart hydrophobic surface. PMID- 30294666 TI - APOBEC3 Mediates Resistance to Oncolytic Viral Therapy. AB - Tumor cells frequently evade applied therapies through the accumulation of genomic mutations and rapid evolution. In the case of oncolytic virotherapy, understanding the mechanisms by which cancer cells develop resistance to infection and lysis is critical to the development of more effective viral-based platforms. Here, we identify APOBEC3 as an important factor that restricts the potency of oncolytic vesicular stomatitis virus (VSV). We show that VSV infection of B16 murine melanoma cells upregulated APOBEC3 in an IFN-beta-dependent manner, which was responsible for the evolution of virus-resistant cell populations and suggested that APOBEC3 expression promoted the acquisition of a virus-resistant phenotype. Knockdown of APOBEC3 in B16 cells diminished their capacity to develop resistance to VSV infection in vitro and enhanced the therapeutic effect of VSV in vivo. Similarly, overexpression of human APOBEC3B promoted the acquisition of resistance to oncolytic VSV both in vitro and in vivo. Finally, we demonstrate that APOBEC3B expression had a direct effect on the fitness of VSV, an RNA virus that has not previously been identified as restricted by APOBEC3B. This research identifies APOBEC3 enzymes as key players to target in order to improve the efficacy of viral or broader nucleic acid-based therapeutic platforms. PMID- 30294667 TI - miR-93 Promotes the Growth and Invasion of Prostate Cancer by Upregulating Its Target Genes TGFBR2, ITGB8, and LATS2. AB - This study aimed to evaluate the effects of miR-93 on the growth and invasiveness of prostate cancer (PC) cells (PCCs). Real-time PCR was carried out to detect the expression of miR-93 in the PC tissues and cell lines. The adjacent normal tissues served as controls. For in vitro experiments, methyl thiazolyl tetrazolium, clone formation, tumor cell invasion assays, and western blot analysis (WBA) were performed to confirm the variations in the proliferation and invasiveness of PCCs, prior and subsequent to transfection with an miR-93 antisense oligonucleotide (ASO), which blocks miR-93 binding to its target. Furthermore, the effect of miR-93 on the proliferation of PCCs was examined. Finally, the expression levels of the target genes of miR-93 were determined by WBA. miR-93 expression was higher in PC tissues than in the adjacent normal tissues, and a reduction in the miR-93 level remarkably inhibited the proliferation and invasiveness of PCCs. Moreover, miR-93 enhanced the expression of its target genes TGFBetaR2, ITGB8, and LATS2. The results of this study suggest that miR-93 may promote the proliferation and invasion of PCCs by upregulating its target genes TGFBR2, ITGB8, and LATS2. PMID- 30294668 TI - Systematic Analysis of Transmitter Coexpression Reveals Organizing Principles of Local Interneuron Heterogeneity. AB - Broad neuronal classes are surprisingly heterogeneous across many parameters, and subclasses often exhibit partially overlapping traits including transmitter coexpression. However, the extent to which transmitter coexpression occurs in predictable, consistent patterns is unknown. Here, we demonstrate that pairwise coexpression of GABA and multiple neuropeptide families by olfactory local interneurons (LNs) of the moth Manduca sexta is highly heterogeneous, with a single LN capable of expressing neuropeptides from at least four peptide families and few instances in which neuropeptides are consistently coexpressed. Using computational modeling, we demonstrate that observed coexpression patterns cannot be explained by independent probabilities of expression of each neuropeptide. Our analyses point to three organizing principles that, once taken into consideration, allow replication of overall coexpression structure: (1) peptidergic neurons are highly likely to coexpress GABA; (2) expression probability of allatotropin depends on myoinhibitory peptide expression; and (3) the all-or-none coexpression patterns of tachykinin neurons with several other neuropeptides. For other peptide pairs, the presence of one peptide was not predictive of the presence of the other, and coexpression probability could be replicated by independent probabilities. The stochastic nature of these coexpression patterns highlights the heterogeneity of transmitter content among LNs and argues against clear-cut definition of subpopulation types based on the presence of single neuropeptides. Furthermore, the receptors for all neuropeptides and GABA were expressed within each population of principal neuron type in the antennal lobe (AL). Thus, activation of any given LN results in a dynamic cocktail of modulators that have the potential to influence every level of olfactory processing within the AL. PMID- 30294669 TI - Idiosyncratic, Retinotopic Bias in Face Identification Modulated by Familiarity. AB - The perception of gender and age of unfamiliar faces is reported to vary idiosyncratically across retinal locations such that, for example, the same androgynous face may appear to be male at one location but female at another. Here, we test spatial heterogeneity for the recognition of the identity of personally familiar faces in human participants. We found idiosyncratic biases that were stable within participants and that varied more across locations for low as compared to high familiar faces. These data suggest that like face gender and age, face identity is processed, in part, by independent populations of neurons monitoring restricted spatial regions and that the recognition responses vary for the same face across these different locations. Moreover, repeated and varied social interactions appear to lead to adjustments of these independent face recognition neurons so that the same familiar face is eventually more likely to elicit the same recognition response across widely separated visual field locations. We provide a mechanistic account of this reduced retinotopic bias based on computational simulations. PMID- 30294671 TI - Marijuana Induced Type I Brugada Pattern: A Case Report. AB - Marijuana is the most common drug of abuse in the United States. Marijuana acts on cannabinoid receptors CB1, CB2 and another distinct endothelial receptor. Marijuana is known to cause tachycardia, hypotension and hypertension. Various arrhythmias including atrial fibrillation, atrial flutter, II degree AV block, ventricular fibrillation, ventricular tachycardia, asystole and brugada pattern associated with marijuana use have been reported. We here present an interesting case of Type I Brugada pattern in electrocardiography (ECG) in a 36 year old healthy African American male who presented after smoking four joints. Urine toxicology test proved marijuana use. Acute coronary syndrome was ruled out, coronary angiogram revealed normal coronaries, 2D echocardiogram showed no evidence of structural heart disease. Upon resolution of Brugada pattern in ECG, procainamide challenge performed in electrophysiology laboratory did not induce Brugada pattern. Patient was asked to return to hospital if he developed fever that did not resolve with antipyretics. Further studies are required to to understand the effect of marijuana on cardiac ion channels. PMID- 30294670 TI - Cocaine Exposure Modulates Perineuronal Nets and Synaptic Excitability of Fast Spiking Interneurons in the Medial Prefrontal Cortex. AB - We previously reported that perineuronal nets (PNNs) are required for cocaine associated memories. Perineuronal nets are extracellular matrix that primarily surrounds parvalbumin (PV)-containing, GABAergic fast-spiking interneurons (FSIs) in the medial prefrontal cortex (mPFC). Here we measured the impact of acute (1 d) or repeated (5 d) cocaine exposure on PNNs and PV cells within the prelimbic and infralimbic regions of the mPFC. Adult rats were exposed to 1 or 5 d of cocaine and stained for PNNs (using Wisteria floribunda agglutinin) and PV intensity 2 or 24 h later. In the prelimbic and infralimbic PFC, PNN staining intensity decreased 2 h after 1 d of cocaine exposure but increased after 5 d of cocaine exposure. Cocaine also produced changes in PV intensity, which generally lagged behind that of PNNs. In the prelimbic PFC, both 1 and 5 d of cocaine exposure increased GAD65/67 puncta near PNN-surrounded PV cells, with an increase in the GAD65/67-to-VGluT1 puncta ratio after 5 d of cocaine exposure. In the prelimbic PFC, slice electrophysiology studies in FSIs surrounded by PNNs revealed that both 1 and 5 d of cocaine exposure reduced the number of action potentials 2 h later. Synaptic changes demonstrated that 5 d of cocaine exposure increased the inhibition of FSIs, potentially reducing the inhibition of pyramidal neurons and contributing to their hyperexcitability during relapse behavior. These early and rapid responses to cocaine may alter the network stability of PV FSIs that partially mediate the persistent and chronic nature of drug addiction. PMID- 30294672 TI - A Rare Case of Second Degree Mobitz Type II AV Block Associated with Cocaine Use. AB - Cocaine is a commonly abused illicit drug in the United States. The complex effects of cocaine on the conduction system of the human heart has not been completely understood. Cocaine acts as a sympathomimetic by inhibition of reuptake of neuronal catecholamines, leading mostly to tachyarrhythmias on presentation. However, cocaine also exerts other effects on the conduction system including sympathomimetic, sino-bradycardic as well as local anesthetic properties. While Multiple cases of atrioventricular (AV) conduction blocks including first degree AV block, Mobitz type I and third degree AV blocks have been previously reported, we hereby present the first case report of cocaine- induced Mobitz type II second degree AV block. This case occurred in a 55 year old woman who presented with retrosternal chest pressure and tested positive for cocaine abuse as documented by urine toxicology test. Patient spontaneously converted to normal sinus rhythm the following day post admission to the hospital. Cocaine is known to inhibit sodium channels and thus has been known to decrease SA node automaticity and conduction via AV node. Electrophysiology studies have previously confirmed cocaine mediated delay in impulse conduction and repolarization. Though rare, physicians should be aware of the possibility of bradyarrhythmias associated with cocaine abuse in order to apply standard therapy such as pacemaker in the event of non-resolution of this serious arrhythmia.

AB - Marijuana abuse is rapidly growing and currently it is the most coimnon drug of abuse in the United States due to increased legalization for recreational and medicinal use. Delta 9-tetrahydrocannibol, the main psychoactive compound in marijuana, acts via the endocannabinoid system to elicit various cardiovascular physiological effects, and has been associated with many adverse cardiovascular effects such as acute coronary syndrome, arrhythmias, and sudden cardiac death that have previously been reported by our group and others. We present a case of a 30-year-old African-American male with no cardiovascular disease (CVD) risk factors with recurrent ST-segment elevation myocardial infarctions (STEMI) whose coronary angiography revealed recurrent 100% occlusion of the left anterior descending artery (LAD) in the setting of marijuana smoking. It was the patient's third STEMI with 100% occlusion of the LAD with each STEMI secondary to thrombosis of a different region of the LAD. Marijuana use was confirmed by urine toxicology screening at each STEMI presentation. Coronary angiography on multiple occasions was negative for stenosis of other epicardial coronary arteries, and coronary calcimn scoring was zero. Evaluation for other cardiovascular risk factors including family history of premature coronary artery disease, dyslipidemia, diabetes, and hypercoagulable disorders was negative. Further studies are required to elucidate the mechanisms of marijuana-associated coronary thrombosis and myocardial infarction. PMID- 30294675 TI - Necroptosis: MLKL Polymerization. AB - Necroptosis is a subtype of regulated necrosis that occurs when caspases are inhibited or fail to activate. Stimulus of cell death receptors results in a signaling cascade that triggers caspase independent, immunogenic cell death. The core pathway relies on receptor interacting protein kinase (RIPK) 1 and 3, which interact through their receptor homotypic interacting motif (RHIM) domains, and form amyloid-like structures termed the necrosome. RIPK3 recruits and phosphorylates mixed lineage kinase domain-like pseudokinase (MLKL), the terminal mediator in the necroptotic pathway. MLKL polymerizes to form a second amyloid like structure that causes cell membrane disruption resulting in cell death. Although the core necroptosis pathway has been elucidated, the details of MLKL membrane translocation and membrane disruption remain an open area of research.

The Learning Health System (LHS) has the potential to significantly improve health care quality using patient-centered design, data analytics, and continuous improvement. To ensure that health disparities are also being addressed, targeted approaches must be used. This document sets forth a practical framework to incorporate health equity into a developing LHS. Using a case study approach, the framework is applied to 2 projects focused on the reduction of health disparities to highlight its application. PMID- 30294678 TI - Partial Deletion of the Long Arm of Chromosome 7: A Case Report. AB - Study advances with a childhood case of partial deletion of the long arm of chromosome 7. The patient is a 36-month-old girl with growth retardation, mild mental retardation and delayed bone age. She showed no signs of hypotelorism, upslanting palpebral fissures, epicanthal folds, low-set ears, or flat and broad nasal bridge. Microarray testing using the Affymetrix CytoScan HD array revealed an approximately 58 kb deletion at 7q31.1 in the girl and her father, suggesting paternal origin. As the patient had no characteristic facial features, 7q deletions had not been considered. This case broadens the range of case presentations for microdeletions of chromosome 7.

AB - The pathogenic bacterium Brucella abortus codes for a multi-domain dimeric cytoplasmic histidine kinase called LOV-HK, which is a key blue light-activated virulence factor in this microorganism. The structural basis of the light activation mechanism of this protein remains unclear. In this work, full-length LOV-HK was cloned, expressed and purified. The protein was activated by light and crystallized under a controlled illumination environment. The merge of 14 individual native data sets collected on a single crystal resulted in a complete X-ray diffraction data set to a resolution of 3.70 A with over 2 million reflections. Crystals belong to space group P212121, with unit-cell parameters a = 95.96, b = 105.30, c = 164.49 A with a dimer in the asymmetric unit. Molecular replacement with Phaser using the individual domains as search models allowed for the reconstruction of almost the whole protein. Very recently, improved LOV-HK crystals led to a 3.25-A resolution dataset. Refinement and model building is underway. This crystal model will represent one of the very few examples of a multi-domain histidine kinase with known structure. PMID- 30294680 TI - Soyasapogenols reduce cellular triglyceride levels in 3T3-L1 mouse adipocyte cells by accelerating triglyceride lipolysis. AB - Soyasapogenol is a soyasaponin aglycone, which has been suggested to exert a more potent function than the glycoside form. In this study, the effect of soyasapogenol A and B on cultured adipocyte cell function was investigated using mouse 3T3-L1 adipocyte cells. 3T3-L1 cells were treated with insulin, dexamethasone, and 3-isobutyl-1-methylxanthine for differentiation to adipocytes, and the cells were then cultured in the presence of soyasapogenol A or B (6.25 or 12.5 uM). The media were harvested and refreshed every 2 d. After a 10 d culture, the cells were harvested and the triglyceride content of the cells was determined. The triglyceride content of soyasapogenol B-treated cells was significantly lower than those of vehicle-treated cells. Glycerol and free fatty acid levels in the soyasapogenol-treated cell media were higher than those in vehicle cells. However, there was no difference in the level of adipose triglyceride lipase among soyasapogenol A-, soyasapogenol B-, and vehicle-treated cells. The secreted adiponectin and resistin levels of soyasapogenol-treated cell media were also different compared with those of vehicle-treated cells. Especially, the secreted resistin level in soyasapogenol B-treated cell media was obviously reduced compared with that of vehicle-treated cells. Taken together, these results suggest that soyasapogenol B exerted an anti-obesity and anti diabetic effect on adipocytes by lowering the cellular triglyceride level by accelerating triglyceride lipolysis with reduced resistin secretion. PMID- 30294682 TI - Pharmacokinetics and safety/efficacy of levodopa pro-drug ONO-2160/carbidopa for Parkinson's disease. AB - We conducted a phase I study investigating the efficacy, safety, and tolerability of ONO-2160, a newly developed levodopa pro-drug, and carbidopa compared with levodopa and carbidopa to stabilize levodopa plasma concentration fluctuations in Japanese patients with Parkinson's disease. In an open-label two-period design, patients (n = 12) with Parkinson's disease received levodopa and carbidopa for 3 days before 7 days of treatment with ONO-2160 and carbidopa. Patients were primarily evaluated using the Unified Parkinson's Disease Rating Scale Part III, a Parkinson's disease symptom diary, and analysis of adverse events. Pharmacokinetic analysis of plasma levodopa concentration was also performed. ONO 2160 and carbidopa therapy stabilized effective plasma levodopa concentration. No adverse events with safety concerns were observed. The combination of ONO-2160 and carbidopa produced a prolonged and stable plasma levodopa concentration with a reduction in Unified Parkinson's Disease Rating Scale Part III total scores. The combination was well tolerated, with no safety concerns, when administered to Japanese patients with Parkinson's disease. PMID- 30294681 TI - Potentials and challenges of diffusion-weighted magnetic resonance imaging in radiotherapy. AB - Purpose: To review the potential and challenges of integrating diffusion weighted magnetic resonance imaging (DWI) into radiotherapy (RT). Content: Details related to image acquisition of DWI for RT purposes are discussed, along with the challenges with respect to geometric accuracy and the robustness of quantitative parameter extraction. An overview of diffusion- and perfusion-related parameters derived from mono- and bi-exponential models is provided, and their role as potential RT biomarkers is discussed. Recent studies demonstrating potential of DWI in different tumor sites such as the head and neck, rectum, cervix, prostate, and brain, are reviewed in detail. Conclusion: DWI has shown promise for RT outcome prediction, response assessment, as well as for tumor delineation and characterization in several cancer types. Geometric and quantification robustness is challenging and has to be addressed adequately. Evaluation in larger clinical trials with well designed imaging protocol and advanced analysis models is needed to develop the optimal strategy for integrating DWI in RT. PMID- 30294683 TI - Surgical Treatment of Jejunal Artery Aneurysm. AB - Introduction: A jejunal artery aneurysm (JAA) is rare and has few specific symptoms. Endovascular repair is widely used in the treatment of jejunal artery aneurysms; however, some patients still require open repair. Report: A 59 year old man underwent open surgery with resection of the aneurysm and reconstruction using a saphenous vein graft. Histopathological examination revealed heterotopic pancreas around the aneurysm. Discussion: Inflammation as a result of heterotopic pancreas was suspected as the cause of JAA. The advantage of open repair is to explore intestinal ischaemia directly. Furthermore, revascularisation with a saphenous vein graft may remove the possibility of post-operative intestinal ischaemia. PMID- 30294684 TI - A Missing Posterior Division of the Internal Iliac Artery. AB - Introduction: To date, multiple variations in the pelvic vasculature have been reported. In this case report, a rare, so far unreported, branching anomaly of the internal iliac artery on the left side of a male human pelvis is described. Report: The complete posterior division of the internal iliac artery was shown to be missing on dissection of a 73 year old male cadaver. The iliolumbar artery, the lateral sacral arteries, and the superior gluteal artery originated unilaterally (on the left pelvis) directly from the common iliac artery. Discussion: No alteration was observed in the supplied structures of the left pelvic region, including the respective muscles, the sacrum, or the hip joint. PMID- 30294685 TI - Kindred spirits? AB - In this commentary, I reflect on the connections and strains between various efforts to expand options for family-making, to reduce the inequities that structure family-making through assisted reproduction and adoption, to secure and protect reproductive rights, and to pursue reproductive justice. I suggest that two threads connect these various aspects of reproductive politics: the commitment to self-determination, and an expanded understanding of kinship beyond the nuclear and the biological. These two themes stand in complicated tension - visible in debates over the ethics of surrogacy, for instance, and in the ways that queer family-making is facilitated, in part, by class and racial inequalities - that need to be confronted head-on. I conclude with some examples of what political kinship built around family justice can and does look like at the level of concrete action.

PMID- 30294687 TI - Stem cell factor induces polarization of microglia to the neuroprotective phenotype in vitro. AB - Microglia are classified mainly into the M1 or M2 phenotypes, which evoke either proinflammatory or neuroprotective responses. Given the association of microglia with the pathogenesis of neuronal diseases, they are in focus as therapeutic targets for the treatment of such conditions. Stem cell factor (SCF) is a ligand for the c-kit receptor, one of the differentiation factors for bone marrow cells. In this study, characteristics of SCF-activated microglia and their effects on neurons were analyzed to investigate the therapeutic potential of SCF in neuronal diseases. SCF was found to induce proliferation, migration, and phagocytosis of microglia. In addition, SCF-derived microglia showed a neuroprotective phenotype expressing anti-inflammatory cytokines, growth factors, and M2 markers as compared to the phenotype shown by granulocyte macrophage-colony stimulating factor-derived microglia expressing inflammatory cytokines and M1 markers. Furthermore, supernatant medium from SCF-activated microglia enhanced cell proliferation and protection from cell death in NSC-34 neuronal cells. We conclude that SCF modulates microglial functions and induces activation of the neuroprotective effects of microglia, which could be used for treatment of neuronal diseases. PMID- 30294688 TI - Calcined magnesite as an adsorbent for cationic and anionic dyes: characterization, adsorption parameters, isotherms and kinetics study. AB - The ability of calcined magnesite for Methylene Blue (MB), Direct Red 81 (DR81), Methyl Orange (MO) and Crystal Violet (CV) dye removal was evaluated in this study. The experiments were designed to test the hypothesis that alkaline earth carbonates can remove dyes from water through a combination of sorption and coagulative reactions involving Mg2+. To achieve that, several operational factors like residence time, dosage, adsorbent concentration and temperature were appraised. The batch study proved that calcined magnesite is effective in the treatment of MB, DR81, CV and MO contaminated water and moreover it performed well in terms of color removal. The adsorption equilibrium data were analysed by the Langmuir, Freundlich, Dubinin-Radushkevich and Temkin isotherm models, and the Dubinin-Radushkevich and Temkin models were found to be the most appropriate fit to MB and MO dyes respectively. The adsorption kinetics process primarily followed the Elovich and Pseudo-second order model, a possible indication that chemisorption was the rate limiting step during the dye uptake process. With the adsorption-desorption cycle repeated four times, the calcined magnesite regeneration efficiency for DR81 and MO loaded dyes remained very high. According to the results of this study, it can be concluded that calcined magnesite can be used effectively for the adsorption of MB, DR81, CV and MO from wastewater. PMID- 30294689 TI - Unknown genes, Cebelin and Cebelin-like, predominantly expressed in mouse brain. AB - We identified two genes, Cebelin and Cebelin-like, encoding unknown proteins in mice. Cebelin and Cebelin-like consist of 168 and 167 amino acids with putative secreted signal sequences. However, Cebelin and Cebelin-like are cellular proteins not secreted proteins. Cebelin and Cebelin-like were predominantly expressed in the brain among major tissues examined. The expression of Cebelin in the brain was predominantly detected in the internal granule layer of the cerebellum. PMID- 30294690 TI - A first step towards a model for teachers' adoption of ICT pedagogy in schools. AB - It is important to identify and understand important factors underpinning the integration of information and communication technology (ICT) in schools. And, it is important that ICT is adopted in a sound pedagogical manner. The aim with this study was to suggest a model for the actual use of ICT in schools and how it may be related to important factors such as technological pedagogical expectations. The design of the model was inspired by TAM2 and UTAUT models, but with some modifications. We have developed a model which highlight the pedagogical aspects beyond the technical ones. Furthermore, our suggested model also include the adoption of digital techniques in everyday life as a potential predictor of adoption of ICT at work. The sample consists of 122 teachers and we analyzed the model with a structural equation model. This study contributes with a suggested model including a new construct for measuring expected performance from a technological pedagogical point of view. This new construct was a significant predictor to actual use of ICT in school. Furthermore we also developed a new construct for adoption of ICT in everyday life, which also was a significant predictor to actual use of ICT in school. PMID- 30294691 TI - Resilience through risk management: cooperative insurance in small-holder aquaculture systems. AB - Aquaculture is a booming industry. It currently supplies almost half of all fish and shellfish eaten today, and it continues to grow faster than any other food production sector. But it is immature relative to terrestrial crop and livestock sectors, and as a consequence it lags behind in terms of the use of aquaculture specific financial risk management tools. In particular, the use of insurance instruments to manage weather related losses is little used. In the aquaculture industry there is a need for new insurance products that achieve both financial gains, in terms of reduced production and revenue risk, and environmental wins, in terms of incentivizing improved management practices. Here, we have developed a cooperative form of indemnity insurance for application to small-holder aquaculture communities in developing nations. We use and advance the theory of risk pools, applying it to an aquaculture community in Myanmar, using empirical data recently collected from a comprehensive farm survey. These data were used to parameterize numerical simulations of this aquaculture system with and without a risk pool. Results highlight the benefits and costs of a risk pool, for various combinations of key parameters. This information reveals a path forward for creating new risk management products for aquaculturalists around the world. PMID- 30294693 TI - Reducing electric energy consumption in linear Fresnel collector solar fields coupled to thermal desalination plants by optimal mirror defocusing. AB - In many parts of the world, desalination is the only viable and economic solution to the problem of fresh water shortage. The current commercial desalination technologies rely on fossil fuels and are thus associated with high greenhouse gas emissions that are a major cause of climatic changes. Solar thermal-driven multi-effect distillation with thermal vapor compression is a clean alternative to conventional desalination technologies. To comprehend this process, as well as its features and limitations, extensive modeling is required. In this work, we proposed a plant design based on a solar field with a linear Fresnel collector that supplies heat to a multi-effect distillation plant with thermal vapor compression. The solar desalination plant model is implemented in the Engineering Equation Solver (EES). The system performance is investigated and a control strategy for reducing electric pumping is proposed. Results showed that 1 m2 of the solar field produces 8.5 m3 of distillate per year. The proposed control strategy resulted in a 40% reduction in electric pumping energy. Our results highlight the versatility of the linear Fresnel collector when coupled with thermal desalination. PMID- 30294692 TI - In vitro alpha-amylase, alpha-glucosidase, lipase inhibitory and cytotoxic activities of tuber extracts of Kedrostis africana (L.) Cogn. AB - Kedrostis africana, is a tuberous plant commonly used by traditional healers in the Eastern Cape Province of South Africa for the management of obesity. The aim of this study was to investigate the antiobesity and cytotoxic effects of Kedrostis africana extracts in vitro The alpha-amylase, alpha-glucosidase and lipase inhibitory activities of aqueous and ethanol extracts of Kedrostis africana tuber were investigated while the cytotoxic effects of these extracts were analyzed using Hoechst 33342 and propidium iodide (PI) dual staining in combination with Molecular Devices ImageXpress Micro XLS Widefield microscope for high content analysis on human cervical (HeLa) cell line. The ethanol extract exhibited the strongest inhibitory effect on pancreatic lipase (IC50 = 381.86 MUg/ml) and on alpha-glucosidase (IC50 = 157.99 MUg/mL) while the aqueous extract has strongest alpha-amylase (IC50 = 439.45 MUg/ml). Both tuber extracts were found nontoxic at tested concentrations on HeLa cell lines as confirmed by the Hoechst 33342 and propidium iodide dual staining respectively. This study revealed that both the aqueous and ethanol tuber extract of K. africana exerts a certain degree of inhibitory effect on alpha-amylase, alpha-glucosidase and lipase and were also nontoxic to HeLa cell line at tested concentrations. PMID- 30294694 TI - An updated review on factors and their inter-linked influences on photovoltaic system performance. AB - Globally installed solar photovoltaics (PV) capacity has crossed three hundred gigawatts and is increasing each year. As the share of solar PV in the energy mix of a country increases, forecasting PV power available will be crucial. To forecast the instantaneous and long-term PV power output, understanding the factors influencing them is necessary. In this view, this work elaborates on the factors that impact the PV system through tabulation and graphical explanation. Further, a discussion of the articles related to the dust-induced change in performance is made. To understand the impact of dust on solar PV systems in depth, advanced instrumentation and methodologies have been used in the past few years. One of the methods is the measurement of spectral transmittance/reflectance/absorptance of the dust layer on the PV panel. This has led to the question whether a thin layer of some specific dust can be beneficial by absorbing infrared (IR) heat and hence allowing the PV cells to operate at a lower temperature. Many controlled experiments in the laboratory have been made using the artificial dust and sun simulators; and such studies aid in the development of numerical models. Research in modeling, mathematical analysis (from first principles) of dust deposition, and calculation of its impact on panels have been given importance in recent years. Outdoor experiments are relatively more common than other modes of research in this field. Studies involving the interaction of deposited dust with spectral radiation, improving the correlation between artificial and natural dust deposition, the interplay between dust and atmospheric parameters are to be encouraged.

AB - In this study, a simple Simulink model was designed and presented which can describe the overall operation of seismograph based on the desired input and output response. By converting Laplace to seismograph equations and by defining Numerator and Denominator fractions to Num. and Den. (Numerator and Denominator) transfer WWSSN (World-Wide Standard Seismographic Network) functions, the changeability of pole-zero was taken into consideration which indicates the stability and instability of the system layout with respect to pole - zero layout. In fact, the poles and zeros are placed in the seismograph response based on frequency, amplitude and phase (FAP) and are analyzed well. Through this method can also be used to study seismograph transfer function to predict the seismograph output in environments with different seismic noise and to select the most appropriate value for the parameters controlling the output of the device. PMID- 30294697 TI - Flavonoids and tannin composition of Bambara groundnut (Vigna subterranea) of Mpumalanga, South Africa. AB - Bambara groundnut (Vigna subterranea) an indigenous legume proclaimed to have medicinal properties within rural areas. Therefore, this study aimed to identify possible medicinal properties of Bambara groundnut (BGN). Flavonoids and tannins were highly concentrated in the red and brown BGN hulls. Among the flavonoid compounds rutin was observed in highest concentrations in brown hull (24.458 +/- 0.234 mg g-1) and myricetin (1.800 +/- 0.771 mg g-1). While among tannin compounds chlorogenic acid was found in highest concentrations (0.115 +/- 0.199 mg g-1) and ellagic acid in red hull (0.105 +/- 0.082 mg g-1). The form and colour of the BGN were all important factors to optimize the best extraction yield of phytochemicals. Overall the hulls of the BGN were the optimum source of flavonoids and tannins. PMID- 30294696 TI - Intermittent administration of a leucine-deprived diet is able to intervene in type 2 diabetes in db/db mice. AB - Continuous deficiency of leucine, a member of branched chain amino acids, is able to reduce obesity and improve insulin sensitivity in mice. Intermittent fasting has been shown to be effective in intervention of metabolic disorders including diabetes. However, it is unknown whether intermittent leucine deprivation can intervene in type 2 diabetes progression. We administered leucine-deprived food every other day in db/db mice, a type 2 diabetes model, for a total of eight weeks to investigate the interventional effect of intermittent leucine deprivation. Intermittent leucine deprivation significantly reduces hyperglycemia in db/db mice independent of body weight change, together with improvement in glucose tolerance and insulin sensitivity. The total area of pancreatic islets and beta cell number are increased by intermittent leucine deprivation, accompanied by elevated proliferation of beta cells. The expression level of Ngn3, a beta cell progenitor marker, is also increased by leucine-deleted diet. However, leucine deficiency engenders an increase in fat mass and a decrease in lean mass. Lipid accumulation in the liver is elevated and liver function is compromised by leucine deprivation. In addition, leucine deficiency alters the composition of gut microbiota. Leucine deprivation increases the genera of Bacteroides, Alloprevotella, Rikenellaceae while reduces Lachnospiraceae and these changes are correlated with fasting blood glucose levels of the mice. Collectively, our data demonstrated that intermittent leucine deprivation can intervene in the progression of type 2 diabetes in db/db mice. However, leucine deficiency reduces lean mass and aggravates hepatic steatosis in the mouse. PMID- 30294698 TI - Two-step recruitment process optimizes retention in FLEX clinical trial. AB - Introduction: The Flexible Lifestyle Empowering Change Study (FLEX) is a multi site randomized controlled trial to test the efficacy of an adaptive behavioral intervention to promote self-management and improve glycemic control for adolescents with type 1 diabetes mellitus. A two-step recruitment process was used to optimize study retention by facilitating informed decision-making regarding participation. Methods: Those who expressed interest at first contact were given more detailed study information followed by telephone calls to the adolescents and their parents to answer questions and explore potential barriers to participation before making a decision regarding study enrollment. Results: Of 694 eligible adolescents who were invited to participate, 397 (57.2%) expressed interest when initially contacted (Step 1). Upon completion of the follow-up telephone calls (Step 2), 276 (39.8%) still agreed to participate; and 258 (37.2%) enrolled and completed a baseline visit with a parent/guardian. Completion rates for measurement visits remained high throughout the study, with an end-of-study retention rate of 93.4%; and only 12 (4.7%) families withdrew from the study. Conclusion: The two-step recruitment process encourages potential participants to thoughtfully evaluate their willingness to participate, as well as their ability to make a commitment to the full completion of study requirements. When demonstrating the efficacy of a randomized controlled trial, it may be preferable to accept lower recruitment rates in order to optimize retention rates. The additional time and effort required to implement this two step process is worthwhile. With a high retention rate, we can be more confident that the outcomes of the randomized controlled trial actually reflect the impact of the intervention. PMID- 30294699 TI - Filipinos Fit and Trim - A feasible and efficacious DPP-based intervention trial. AB - Introduction: Filipino Americans are at higher risk for obesity and related Type 2 diabetes (T2D) compared to other Asian subgroups and non-Hispanic whites. Yet, there are limited research studies to reduce health disparities and improve health outcomes for Filipinos. Weight loss lifestyle intervention trials such as the Diabetes Prevention Program (DPP) can reduce obesity and T2D risks through physical activity and healthy eating. Methods: Thus, we conducted a pilot Fit&Trim (DPP-based) intervention study - a randomized controlled trial 3-month intervention augmented with mobile technology + 3-month maintenance follow-up with a waitlist control. The objective assessed the intervention feasibility and potential efficacy to reduce T2D risks in Filipino Americans with overweight/obesity. The overall study goal was a mean 5% weight reduction. Results: Sixty-seven eligible Filipino men and women were enrolled and randomized to either an intervention or waitlist control group. Participant retention was 91%. In Phase 1 (baseline to 3-months), the intervention group had greater weight reduction compared to the waitlist control (-4.3% vs. -0.88%; cross-level interaction = -0.85 (-1.4, -0.35). In Phase 2 (3- to 6-months), after receiving the Fit&Trim intervention, the waitlist group also had similar significant weight reduction [-4.8% (- 0.75 (-0.92, -0.58)]. A majority of intervention group (57%) also maintained their weight loss. Overall, 41% of study participants achieved a 5% weight loss. Conclusion: The Fit&Trim intervention demonstrated feasibility and potential efficacy for Filipino Americans. Findings warrant a further larger, longer trial to test the Fit&Trim feasibility and effectiveness in a real-world Filipino community setting. ClinicalTrialsgov registration number: NCT02278939.

PMID- 30294700 TI - Bilateral pseudo-internuclear ophthalmoplegia in a patient with myasthenia gravis. AB - Purpose: To report a case of myasthenia gravis presenting with a false localizing sign, a bilateral pseudo internuclear ophthalmoplegia. Observations: A 61 year old male presented with a five-week history of painless binocular oblique diplopia that was associated with fatigue, vocal hoarseness and bilateral ptosis, the latter two of which worsened through the course of the day. Exam was remarkable for an apparent bilateral internuclear ophthalmoplegia (INO). MRI of the brain with and without contrast and MRA of the head and neck were within normal limits. Lab work was positive for anti-AChR binding, blocking, and modulating antibodies, as well as anti-striated muscle and anti-titin antibodies. The patient was initiated on therapy for myasthenia gravis. Conclusion and importance: Although myasthenia gravis often presents with ptosis or diplopia, rarely patients may develop pseudo-INO secondary to extraocular muscle weakness. True INO occurs with damage to the medial longitudinal fasciculus, a myelinated tract of fibers that controls yoked horizontal eye movements. Clinicians should be suspicious of the false localizing sign of a pseudo-INO associated with myasthenia gravis when more common causes of INO have been excluded. PMID- 30294702 TI - Potential role of a ventral nerve cord central pattern generator in forward and backward locomotion in Caenorhabditis elegans. AB - C. elegans locomotes in an undulatory fashion, generating thrust by propagating dorsoventral bends along its body. Although central pattern generators (CPGs) are typically involved in animal locomotion, their presence in C. elegans has been questioned, mainly because there has been no evident circuit that supports intrinsic network oscillations. With a fully reconstructed connectome, the question of whether it is possible to have a CPG in the ventral nerve cord (VNC) of C. elegans can be answered through computational models. We modeled a repeating neural unit based on segmentation analysis of the connectome. We then used an evolutionary algorithm to determine the unknown physiological parameters of each neuron so as to match the features of the neural traces of the worm during forward and backward locomotion. We performed 1,000 evolutionary runs and consistently found configurations of the neural circuit that produced oscillations matching the main characteristic observed in experimental recordings. In addition to providing an existence proof for the possibility of a CPG in the VNC, we suggest a series of testable hypotheses about its operation. More generally, we show the feasibility and fruitfulness of a methodology to study behavior based on a connectome, in the absence of complete neurophysiological details. PMID- 30294703 TI - NeuroCave: A web-based immersive visualization platform for exploring connectome datasets. AB - We introduce NeuroCave, a novel immersive visualization system that facilitates the visual inspection of structural and functional connectome datasets. The representation of the human connectome as a graph enables neuroscientists to apply network-theoretic approaches in order to explore its complex characteristics. With NeuroCave, brain researchers can interact with the connectome-either in a standard desktop environment or while wearing portable virtual reality headsets (such as Oculus Rift, Samsung Gear, or Google Daydream VR platforms)-in any coordinate system or topological space, as well as cluster brain regions into different modules on-demand. Furthermore, a default side-by side layout enables simultaneous, synchronized manipulation in 3D, utilizing modern GPU hardware architecture, and facilitates comparison tasks across different subjects or diagnostic groups or longitudinally within the same subject. Visual clutter is mitigated using a state-of-the-art edge bundling technique and through an interactive layout strategy, while modular structure is optimally positioned in 3D exploiting mathematical properties of platonic solids. NeuroCave provides new functionality to support a range of analysis tasks not available in other visualization software platforms. PMID- 30294704 TI - Effect of different spatial normalization approaches on tractography and structural brain networks. AB - To facilitate the comparison of white matter morphologic connectivity across target populations, it is invaluable to map the data to a standardized neuroanatomical space. Here, we evaluated direct streamline normalization (DSN), where the warping was applied directly to the streamlines, with two publically available approaches that spatially normalize the diffusion data and then reconstruct the streamlines. Prior work has shown that streamlines generated after normalization from reoriented diffusion data do not reliably match the streamlines generated in native space. To test the impact of these different normalization methods on quantitative tractography measures, we compared the reproducibility of the resulting normalized connectivity matrices and network metrics with those originally obtained in native space. The two methods that reconstruct streamlines after normalization led to significant differences in network metrics with large to huge standardized effect sizes, reflecting a dramatic alteration of the same subject's native connectivity. In contrast, after normalizing with DSN we found no significant difference in network metrics compared with native space with only very small-to-small standardized effect sizes. DSN readily outperformed the other methods at preserving native space connectivity and introduced novel opportunities to define connectome networks without relying on gray matter parcellations. PMID- 30294705 TI - Catecholaminergic manipulation alters dynamic network topology across cognitive states. AB - The human brain is able to flexibly adapt its information processing capacity to meet a variety of cognitive challenges. Recent evidence suggests that this flexibility is reflected in the dynamic reorganization of the functional connectome. The ascending catecholaminergic arousal systems of the brain are a plausible candidate mechanism for driving alterations in network architecture, enabling efficient deployment of cognitive resources when the environment demands them. We tested this hypothesis by analyzing both resting-state and task-based fMRI data following the administration of atomoxetine, a noradrenaline reuptake inhibitor, compared with placebo, in two separate human fMRI studies. Our results demonstrate that the manipulation of central catecholamine levels leads to a reorganization of the functional connectome in a manner that is sensitive to ongoing cognitive demands. PMID- 30294706 TI - Frequency-based brain networks: From a multiplex framework to a full multilayer description. AB - We explore how to study dynamical interactions between brain regions by using functional multilayer networks whose layers represent different frequency bands at which a brain operates. Specifically, we investigate the consequences of considering the brain as (i) a multilayer network, in which all brain regions can interact with each other at different frequency bands; and as (ii) a multiplex network, in which interactions between different frequency bands are allowed only within each brain region and not between them. We study the second-smallest eigenvalue lambda 2 of the combinatorial supra-Laplacian matrix of both the multiplex and multilayer networks, as lambda 2 has been used previously as an indicator of network synchronizability and as a biomarker for several brain diseases. We show that the heterogeneity of interlayer edge weights and, especially, the fraction of missing edges crucially modify the value of lambda 2, and we illustrate our results with both synthetic network models and real data obtained from resting-state magnetoencephalography. Our work highlights the differences between using a multiplex approach and a full multilayer approach when studying frequency-based multilayer brain networks. PMID- 30294707 TI - Regions of Interest as nodes of dynamic functional brain networks. AB - The properties of functional brain networks strongly depend on how their nodes are chosen. Commonly, nodes are defined by Regions of Interest (ROIs), predetermined groupings of fMRI measurement voxels. Earlier, we demonstrated that the functional homogeneity of ROIs, captured by their spatial consistency, varies widely across ROIs in commonly used brain atlases. Here, we ask how ROIs behave as nodes of dynamic brain networks. To this end, we use two measures: spatiotemporal consistency measures changes in spatial consistency across time and network turnover quantifies the changes in the local network structure around an ROI. We find that spatial consistency varies non-uniformly in space and time, which is reflected in the variation of spatiotemporal consistency across ROIs. Furthermore, we see time-dependent changes in the network neighborhoods of the ROIs, reflected in high network turnover. Network turnover is nonuniformly distributed across ROIs: ROIs with high spatiotemporal consistency have low network turnover. Finally, we reveal that there is rich voxel-level correlation structure inside ROIs. Because the internal structure and the connectivity of ROIs vary in time, the common approach of using static node definitions may be surprisingly inaccurate. Therefore, network neuroscience would greatly benefit from node definition strategies tailored for dynamical networks. PMID- 30294708 TI - Changes in health-related quality of life and work-related outcomes for patients with mild-to-moderate ulcerative colitis receiving short-term and long-term treatment with multimatrix mesalamine: a prospective, open-label study. AB - Background: Ulcerative colitis (UC) is associated with lower health-related quality of life (HRQoL), and with disease activity predicting lower HRQoL and worse work-related outcomes. The current study examined the burden of UC on patients' HRQoL, as well as changes in patients' HRQoL and work-related outcomes following short-term and long-term treatment with multimatrix mesalamine, and their correspondence with changes in disease activity. Methods: Data were from an open-label, multinational, prospective trial (ClinicalTrials.gov identifier: NCT01124149) of 717 adults with active mild-to-moderate UC who were treated with 4.8 g/day multimatrix mesalamine tablets once daily for eight weeks (acute phase). Four-hundred sixty-one patients who achieved partial or complete clinical and endoscopic remission subsequently received treatment with daily 2.4 g/day multimatrix mesalamine for 12 months (maintenance phase). At baseline, Week 8, and Month 12, patients were administered patient-reported outcomes (PRO) measures of HRQoL (the SF-12v2(r) Health Survey [SF-12v2] and Short Inflammatory Bowel Disease Questionnaire) and work-related outcomes (Work Productivity and Activity Impairment questionnaire, UC-specific version). SF-12v2 scores were compared to the U.S. general population using Analysis of Variance models to assess burden of UC on HRQoL. Mixed-effects repeated-measures models compared PRO scores across visits to assess change in PRO scores over time. Correlations examined the correspondence of changes in PRO scores with changes on a modified UC disease activity index (UC-DAI). Results: Baseline burden of disease observed on all SF 12v2 domains was partially eliminated at Week 8 and completely eliminated at Month 12. Statistically significant improvements from baseline were observed at both Week 8 and Month 12 for all PRO scores (all P < 0.001). Decreases in UC-DAI scores significantly predicted improvements in PRO scores during the acute treatment phase. Conclusions: Patients with UC receiving daily multimatrix mesalamine treatment showed significant improvements in all measured domains of HRQoL and work-related outcomes. Patients who achieved partial or complete clinical and endoscopic remission maintained these improvements for most of these domains over 12 months with continued daily treatment. Changes in HRQoL and work related outcomes were inversely related to changes in disease activity. Findings support the effectiveness of multimatrix mesalamine for improving, and sustaining improvements, in HRQoL and work-related outcomes. PMID- 30294709 TI - The relationship between comorbidity medication adherence and health related quality of life among patients with cancer. AB - Background: Studies have demonstrated that comorbidities compound the adverse influence of cancer on health-related quality of life (HRQoL). Comorbidities adversely impact adherence to cancer treatment. Additionally, adherence to medications for comorbidities is positively associated with HRQoL for various diseases. This study used the Center for Disease Control and Prevention's Healthy Days measure of HRQoL to explore the association between HRQoL and adherence to comorbidity medication for elderly patients with cancer and at least one comorbid condition. Methods: We conducted a cross-sectional survey combined with retrospective claims data. Patients with metastatic breast, lung or colorectal cancer were surveyed regarding their HRQoL, comorbidity medication adherence and cancer-related symptoms. Patients reported the number of physical, mental and total unhealthy days in the prior month. The Morisky Medication Adherence 8-point scale was differentiated into moderate/high (> 6) and low (<= 6) comorbidity medication adherence. Results: Of the 1847 respondents, the mean age was 69.2 years, most were female (66.8%) and the majority of the sample had Medicare coverage (88.2%). Low comorbidity medication adherence was associated with significantly more total, mental and physical unhealthy days. Low comorbidity medication adherence was associated with the presence of patient-reported cancer related symptoms. Patients reporting low, as compared to moderate/high, comorbidity medication adherence had 23.4% more unhealthy days in adjusted analysis, P = 0.007. Conclusion: The positive association between low comorbidity medication adherence and the number of unhealthy days suggests that addressing barriers to comorbidity medication adherence during cancer treatment may be an avenue for improving or maintaining HRQoL for older patients with cancer and comorbid conditions. PMID- 30294710 TI - Burden of renal angiomyolipomas associated with tuberous sclerosis complex: results of a patient and caregiver survey. AB - Background: Tuberous sclerosis complex (TSC) is a rare genetic disorder characterized by benign tumors in multiple organs, including non-cancerous kidney lesions known as renal angiomyolipomas. This study's objective is to describe the age-stratified morbidity, treatment patterns, and health-related quality of life of TSC patients with renal angiomyolipomas in the United States. A cross sectional, anonymous web-based survey was conducted with a convenience sample of TSC patients and caregivers identified through a patient advocacy organization. Results: Out of the total sample of 676, 182 respondents reported having kidney complications with 33% of the pediatric group and 25% of the adult group with TSC reporting them. Of those with kidney complications, 110 (60%) reported a diagnosis of renal angiomyolipomas, of which 79 (72%) were adult patients and 31 (28%) were pediatric age patients. Eighty-four percent of the pediatric group and 76% of the adult group reported lesions on both kidneys. Of the patients experiencing involvement of only one kidney, 60% of the pediatric group and 21% of the adult group reported having multiple tumors within the affected kidney. Almost all of the sample (99%) reported seeing a physician and having a procedure or test for TSC in the past year. Less than half the respondents (44%) reported being hospitalized in the past year. Thirty-nine percent reported an emergency room visit as well. Compared to scores for patients with kidney disease, the angiomyolipoma adult patients reported significantly lower Mental Component Summary scores on the SF-12. Conclusions: Renal angiomyolipomas burden leads to frequent healthcare resource use including hospitalization, invasive treatments, and surgical procedures, which result in an impaired mental health related quality of life. PMID- 30294711 TI - Measurement properties of the German version of the IKDC subjective knee form (IKDC-SKF). AB - Purpose: To examine the measurement properties of the German International Knee Documentation Committee Subjective Knee Form (IKDC-SKF) in knee disorder patients. Methods: Three hundred twelve consecutive patients undergoing surgery for anterior cruciate ligament, meniscus and/or cartilage injuries completed the IKDC-SKF, Lysholm Score, Tegner Activity Scale, and Short Form-12 Health Survey before and 6 months post-surgery. IKDC-SKF measurement properties were calculated and patients were also asked to rate the relevance/comprehensibility of the questionnaire items. Results: Reliability was good with high Cronbach's alpha and intraclass correlation coefficients, and standard error of measurement values of 4.4 to 6.0. The smallest detectable change (SDC) ranged from 12.3 to 16.7 points. Validity was good with 90% of all hypotheses confirmed. Confirmatory factor analysis did not show adequate fitting indices within the model. Over half of the items were rated as essential, and all were well comprehended. The majority of hypotheses for responsiveness were confirmed. No floor and ceiling effects were observed. The area under the curve ranged from 0.82 to 0.89 and the minimal important difference was smaller than the SDC. Conclusions: The German IKDC-SKF is a reliable outcome measure with good hypotheses testing and responsiveness, but its MIC and structural/content validity need further analysis. PMID- 30294713 TI - Development of the Diabetes Injection Device Experience Questionnaire (DID-EQ) and Diabetes Injection Device Preference Questionnaire (DID-PQ). AB - Background: Previous research has examined patient perceptions of insulin injection devices. However, injectable medications other than insulin are increasingly used to treat type 2 diabetes, including GLP-1 receptor agonists. No patient-reported outcome (PRO) instruments have been developed taking into account the experiences of patients using newer injection devices, which are often different from devices used for insulin. Therefore, the purpose of this qualitative study was to develop two draft PRO instruments focusing on patients' experiences with these newer injection devices (one instrument assessing perceptions of a single injection device, and another assessing preferences between two devices). Methods: Questionnaire development proceeded in six steps: literature review, interviews with six device experts, concept elicitation interviews with patients (N = 32), preliminary translatability assessment, cognitive interviews with patients (N = 20), and final translatability assessment. Results: Literature review and expert interviews were conducted to inform a concept elicitation interview guide. In concept elicitation in the US, UK, and Germany, patients with type 2 diabetes reported a range of injection features that influenced their perceptions of non-insulin injection devices (e.g., requirements for preparation of the medication/device, issues related to the needle, ease-of-use, portability). Two draft "item pools" were developed based on the literature review, expert interviews, and concept elicitation results. In cognitive interviews, patients recommended minor revisions and indicated that the draft instruments were generally clear, comprehensible, and relevant to their experience with non-insulin injectable medication. The instruments were refined based on the cognitive interviews and translatability assessment, resulting in two questionnaires. Conclusions: The various steps of qualitative research support the content validity of these new PRO instruments, which are the first developed specifically to assess perceptions of non-insulin injection delivery systems. Despite some overlap with insulin-focused questionnaires, the new instruments are distinct from previous instruments (omitting content that would not be relevant to patients receiving non-insulin injectable treatment, while including content that is not included in the insulin focused instruments). This qualitative research yielded two draft questionnaires that are grounded in patient perceptions and ready for psychometric validation studies with larger samples of patients with type 2 diabetes. PMID- 30294714 TI - Psychometric evaluation of the Diabetes Injection Device Experience Questionnaire (DID-EQ) and Diabetes Injection Device Preference Questionnaire (DID-PQ). AB - Background: Previous research has examined patient perceptions of insulin injection devices. However, a range of injectable medications other than insulin are now used to treat type 2 diabetes. No patient-reported outcome (PRO) instruments have been developed taking into account the perceptions of patients using newer injection devices, which are often different from those used in the past. Therefore, the primary purpose of this study was to evaluate a new PRO instrument focusing on patients' experiences with injection devices, including those used for newer treatments such as GLP-1 receptor agonists. Methods: Patients with T2D treated with non-insulin injectable medications were recruited via advertisements and six clinical sites in the US. All participants completed the draft Diabetes Injection Device - Experience Questionnaire (DID-EQ) and additional measures administered for validity assessment. Participants who had experience with two non-insulin injection devices also completed the draft Diabetes Injection Device - Preference Questionnaire (DID-PQ). Analyses focused on item reduction (item performance, exploratory factor analysis), reliability, and validity. Results: One hundred fourty two patients (mean age = 63.0y; 56.3% female) participated. Item reduction yielded a 10-item version of the DID-EQ, including a 7-item Device Characteristics subscale and three global items assessing satisfaction, ease of use, and convenience of the injection device. The DID-EQ demonstrated good internal consistency reliability (Cronbach's alpha of Device Characteristics subscale = 0.80) and 7-day test-retest reliability (ICCs: 0.92 for Device Characteristics subscale; 0.65 to 0.91 for the three global items). Construct validity was demonstrated via correlations with previously validated instruments (e.g., correlations with the DTSQ treatment satisfaction subscale ranged from 0.56 to 0.60, all p < 0.0001; correlations with the TRIM-D Device ranged from 0.63 to 0.77, all p < 0.0001). Descriptive analyses of the DID PQ were conducted with a subset of 27 participants who were able to use it to compare two devices. Conclusions: This psychometric evaluation supports the reliability and validity of the DID-EQ, while providing initial information on the performance of the DID-PQ. These brief questionnaires complement measures of treatment efficacy and provide a more thorough picture of patients' experiences with non-insulin injectable treatments for type 2 diabetes. PMID- 30294712 TI - How do patient reported outcome measures (PROMs) support clinician-patient communication and patient care? A realist synthesis. AB - Background: In this paper, we report the findings of a realist synthesis that aimed to understand how and in what circumstances patient reported outcome measures (PROMs) support patient-clinician communication and subsequent care processes and outcomes in clinical care. We tested two overarching programme theories: (1) PROMs completion prompts a process of self-reflection and supports patients to raise issues with clinicians and (2) PROMs scores raise clinicians' awareness of patients' problems and prompts discussion and action. We examined how the structure of the PROM and care context shaped the ways in which PROMs support clinician-patient communication and subsequent care processes. Results: PROMs completion prompts patients to reflect on their health and gives them permission to raise issues with clinicians. However, clinicians found standardised PROMs completion during patient assessments sometimes constrained rather than supported communication. In response, clinicians adapted their use of PROMs to render them compatible with the ongoing management of patient relationships. Individualised PROMs supported dialogue by enabling the patient to tell their story. In oncology, PROMs completion outside of the consultation enabled clinicians to identify problematic symptoms when the PROM acted as a substitute rather than addition to the clinical encounter and when the PROM focused on symptoms and side effects, rather than health related quality of life (HRQoL). Patients did not always feel it was appropriate to discuss emotional, functional or HRQoL issues with doctors and doctors did not perceive this was within their remit. Conclusions: This paper makes two important contributions to the literature. First, our findings show that PROMs completion is not a neutral act of information retrieval but can change how patients think about their condition. Second, our findings reveal that the ways in which clinicians use PROMs is shaped by their relationships with patients and professional roles and boundaries. Future research should examine how PROMs completion and feedback shapes and is influenced by the process of building relationships with patients, rather than just their impact on information exchange and decision making. PMID- 30294715 TI - Functional connectome of the five-factor model of personality. AB - A key objective of the emerging field of personality neuroscience is to link the great variety of the enduring dispositions of human behaviour with reliable markers of brain function. This can be achieved by analyzing large sets of data with methods that model whole-brain connectivity patterns. To meet these expectations, we exploited a large repository of personality and neuroimaging measures made publicly available via the Human Connectome Project. Using connectomic analyses based on graph theory, we computed global and local indices of functional connectivity (e.g., nodal strength, efficiency, clustering, betweenness centrality) and related these metrics to the five-factor-model (FFM) personality traits (i.e., neuroticism, extraversion, openness, agreeableness, and conscientiousness). The maximal information coefficient was used to assess for linear and non-linear statistical dependencies across the graph 'nodes', which were defined as distinct brain circuits identified via independent component analysis. Multi-variate regression models and 'train/test' machine-learning approaches were also used to examine the associations between FFM traits and connectomic indices as well as to test for the generalizability of the main findings, whilst accounting for age and sex differences. Conscientiousness was the sole FFM trait linked to measures of higher functional connectivity in the fronto-parietal and default mode networks. This might provide a mechanistic explanation of the behavioural observation that conscientious people are reliable and efficient in goal-setting or planning. Our study provides new inputs to understanding the neurological basis of personality and contributes to the development of more realistic models of the brain dynamics that mediate personality differences. PMID- 30294716 TI - DNA damaging agent-based antibody-drug conjugates for cancer therapy. AB - Currently, four antibody-drug conjugates (ADCs) are approved by the Food and Drug Administration or the European Medicine Agency to treat cancer patients. More than 60 ADCs are in clinical development for cancer therapy. More than 60% of ADCs in clinical trials employ microtubule inhibitors as their payloads. A better understanding of payloads other than microtubule inhibitors, especially DNA damaging agents, is important for further development of ADCs. In this review, we highlight an emerging trend of using DNA-damaging agents as payloads for ADCs. This review summarizes recent advances in our understanding gained from ongoing clinical studies; it will help to define the utility of DNA-damaging payloads for ADCs as cancer therapeutics. Future directions of the development of ADCs are also discussed, focusing on targeting drug resistance and combination treatment with immunotherapy. PMID- 30294717 TI - Synthetic Peptide CK2.3 Enhances Bone Mineral Density in Senile Mice. AB - Background: Osteoporosis is a silent disease caused by low bone mineral density that results in bone fractures in 1 out of 2 women and 1 in 4 men over the age of 50. Although several treatments for osteopenia and osteoporosis are available, they have severe side effects and new treatments are desperately needed. Current treatments usually target osteoclasts and inhibit their activity or differentiation. Treatments that decrease osteoclast differentiation and activity but enhance osteogenesis and osteoblast activity are not available. We recently developed a peptide, CK2.3, that induces bone formation and increases bone mineral density as demonstrated by injection over the calvaria of 6 to 9-day-old mice and tail vein injection of 8-week-old mice. CK2.3 also decreased osteoclast formation and activity. However, these studies raise questions: does CK2.3 induce similar results in old mice and if so, what is the effective CK2.3 concentration and, is the bone mineral density of vertebrae of the spinal column increased as well? Methods: CK2.3 was systematically injected into the tail vein of female 6 month old mice with various concentrations of CK2.3: 0.76 MUg/kg, 2.3 MUg/kg, or 6.9 MUg/kg per mice. Mice were sacrificed one week, two weeks, and four weeks after the first injection. Their spines and femurs were collected and analyzed for bone formation. Results: Femur and lumbar spine analyses found increased bone mineral density (BMD) and mineral apposition rate, with greater stiffness observed in femoral samples four weeks after the first injection. Histochemistry showed that osteoclastogenesis was suppressed in CK2.3 treated senile mice. Conclusions: For the first time, this study showed the increase of lumbar spine BMD by CK2.3. Moreover, it showed that enhancement of femur BMD was accompanied by increased femur stiffness only at medium concentration of CK2.3 four weeks after the first injection indicating the maintenance of bone's structural integrity by CK2.3. PMID- 30294718 TI - Seed-Layer Free Zinc Tin Oxide Tailored Nanostructures for Nanoelectronic Applications: Effect of Chemical Parameters. AB - Semiconductor nanowires are mostly processed by complex, expensive, and high temperature methods. In this work, with the intent of developing zinc tin oxide nanowires (ZTO NWs) by low-cost and low-complexity processes, we show a detailed study on the influence of chemical parameters in the hydrothermal synthesis of ZTO nanostructures at temperatures of only 200 degrees C. Two different zinc precursors, the ratio between zinc and tin precursors, and the concentration of the surfactant agent and of the mineralizer were studied. The type and the crystallinity of the nanostructures were found to be highly dependent on the used precursors and on the concentration of each reagent. Conditions for obtaining different ZTO nanostructures were achieved, namely, Zn2SnO4 nanoparticles and ZnSnO3 nanowires with length ~600 nm, with the latter being reported for the first time ever by hydrothermal methods without the use of seed layers. Optical and electrical properties were analyzed, obtaining band gaps of 3.60 and 3.46 eV for ZnSnO3 and Zn2SnO4, respectively, and a resistivity of 1.42 kOmega.cm for single ZnSnO3 nanowires, measured using nanomanipulators after localized deposition of Pt electrodes by e-beam assisted gas decomposition. The low temperature hydrothermal methods explored here proved to be a low-cost, reproducible, and highly flexible route to obtain multicomponent oxide nanostructures, particularly ZTO NWs. The diversity of the synthesized ZTO structures has potential application in next-generation nanoscale devices such as field effect nanotransistors, nanogenerators, resistive switching memories, gas sensors, and photocatalysis. PMID- 30294720 TI - Evaluating Effectiveness of Mass and Continuous Long-lasting Insecticidal Net Distributions Over Time in Madagascar: A Sentinel Surveillance Based Epidemiological Study. AB - Background: The reduction of global malaria burden over the past 15 years is much attributed to the expansion of mass distribution campaigns (MDCs) of long-lasting insecticidal nets (LLIN). In Madagascar, two LUN MDCs were implemented and one district also benefited from a community-based continuous distribution (CB-CD). Malaria incidence dropped but eventually rebounded after a decade. Methods: Data from a sentinel surveillance network over the 2009-2015 period was analyzed. Alerts were defined as w eekly number o f malaria cases exceeding the 90th percentile value for three consecutive weeks. Statistical analyses assessed the temporal relationship between LLIN MDCs and (i) number of malaria cases and (ii) malaria alerts detected, and (iii) the effect of a combination of MDCs and a CB CD in Toamasina District. Findings: Analyses showed an increase of 13.6 points and 21.4 points in the percentile value of weekly malaria cases during the second and the third year following the MDC of LLINs respectively. The percentage of alert-free sentinel sites was 98.2% during the first year after LLIN MDC, 56.7% during the second year and 31.5% during the third year. The number of weekly malaria cases decreased by 14% during the CB-CD in Toamasina District. In contrast, sites without continuous distribution had a 12% increase of malaria cases. Interpretation: These findings support the malaria-preventive effectiveness of MDCs in Madagascar but highlight their limited duration when not followed by continuous distribution. The resulting policy implications are crucial to sustain reductions in malaria burden in high transmission settings. PMID- 30294721 TI - Automatic Archiving versus Default Deletion: What Snapchat Tells Us About Ephemerality in Design. AB - Unlike most social media, where automatic archiving of data is the default, Snapchat defaults to ephemerality: deleting content shortly after it is viewed by a receiver. Interviews with 25 Snapchat users show that ephemerality plays a key role in shaping their practices. Along with friend-adding features that facilitate a network of mostly close relations, default deletion affords everyday, mundane talk and reduces self-consciousness while encouraging playful interaction. Further, although receivers can save content through screenshots, senders are notified; this selective saving with notification supports complex information norms that preserve the feel of ephemeral communication while supporting the capture of meaningful content. This dance of giving and taking, sharing and showing, and agency for both senders and receivers provides the basis for a rich design space of mechanisms, levels, and domains for ephemerality. PMID- 30294719 TI - Sex Differences in Genetic Associations With Longevity. AB - IMPORTANCE: Sex differences in genetic associations with human longevity remain largely unknown; investigations on this topic are important for individualized health care. OBJECTIVE: To explore sex differences in genetic associations with longevity. DESIGN SETTING AND PARTICIPANTS: This population-based case-control study used sex-specific genome-wide association study and polygenic risk score (PRS) analyses to examine sex differences in genetic associations with longevity. Five hundred sixty-four male and 1614 female participants older than 100 years were compared with a control group of 773 male and 1526 female individuals aged 40 to 64 years. All were Chinese Longitudinal Healthy Longevity Study participants with Han ethnicity who were recruited in 1998 and 2008 to 2014. MAIN OUTCOMES AND MEASURES: Sex-specific loci and pathways associated with longevity and PRS measures of joint effects of sex-specific loci. RESULTS: Eleven male specific and 11 female-specific longevity loci (P < 10-5) and 35 male-specific and 25 female-specific longevity loci (10-5 <= P < 10-4) were identified. Each of these loci's associations with longevity were replicated in north and south regions of China in one sex but were not significant in the other sex (P = .13 .97), and loci-sex interaction effects were significant (P < .05). The associations of loci rs60210535 of the LINC00871 gene with longevity were replicated in Chinese women (P = 9.0 * 10-5) and US women (P = 4.6 * 10-5) but not significant in Chinese and US men. The associations of the loci rs2622624 of the ABCG2 gene were replicated in Chinese women (P = 6.8 * 10-5) and European women (P = .003) but not significant in both Chinese and European men. Eleven male-specific pathways (inflammation and immunity genes) and 34 female-specific pathways (tryptophan metabolism and PGC-1alpha induced) were significantly associated with longevity (P < .005; false discovery rate < 0.05). The PRS analyses demonstrated that sex-specific associations with longevity of the 4 exclusive groups of 11 male-specific and 11 female-specific loci (P < 10-5) and 35 male-specific and 25 female-specific loci (10-5 <=P < 10-4) were jointly replicated across north and south discovery and target samples. Analyses using the combined data set of north and south showed that these 4 groups of sex specific loci were jointly and significantly associated with longevity in one sex (P = 2.9 * 10-70 to 1.3 * 10-39) but not jointly significant in the other sex (P = .11 to .70), while interaction effects between PRS and sex were significant (P = 4.8 * 10-50 to 1.2 * 10-16). CONCLUSION AND RELEVANCE: The sex differences in genetic associations with longevity are remarkable, but have been overlooked by previously published genome-wide association studies on longevity. This study contributes to filling this research gap and provides a scientific basis for further investigating effects of sex-specific genetic variants and their interactions with environment on healthy aging, which may substantially contribute to more effective and targeted individualized health care for male and female elderly individuals. PMID- 30294723 TI - Prevalence and factors associated with self-reported chronic obstructive pulmonary disease among adults aged 40-79: the National Health and Nutrition Examination Survey (NHANES) 2007-2012. AB - Introduction: Chronic obstructive pulmonary disease (COPD) is a respiratory disease that often goes undiagnosed, particularly in its early stages. Objective: To examine sociodemographic, general health, and COPD specific factors, including severity of lung obstruction, that are associated with healthcare provider diagnosed COPD among U.S. adults. Methods: NHANES cross-sectional data collected from 2007-2012 on adults aged 40-79 years (n=10,219) were analyzed. The primary outcome was self-reported COPD diagnosis with predictive factors analyzed via chi square and logistic regression analyses. Results: During 2007-2012, 5.2% of US adults aged 40-79 reported being diagnosed with COPD. Among those diagnosed, 50.8% reported fair or poor health, 47.1% were currently smoking cigarettes, 49.1% were taking prescription respiratory medication, 36.4% had moderate or worse lung obstruction, and nearly 90% had one or more respiratory symptoms. Logistic regression revealed positive associations between receiving a COPD diagnosis and the following: being white (AOR: 3.08, 95% CI: 1.82-5.20); being aged 60-79 years (AOR: 1.65, 95% CI: 1.07-2.53); reporting fair/poor health (AOR: 2.91, CI: 1.55-5.46); having 4-9 (AOR: 3.5, CI: 1.3-9.4) or 10 or more healthcare visits in prior year (AOR: 5.06, CI: 1.62-15.77); being a former (AOR: 1.75, CI: 1.2-2.5) or current smoker (AOR: 1.70, CI: 1.17-2.48); having more severe lung obstruction (AOR: 4.90, CI: 3.28-7.32); having 3 or more respiratory symptoms (AOR: 22.07, CI: 12.03-40.49). Conclusions: Multiple factors are associated with self-reported COPD diagnosis with number of reported respiratory symptoms having the strongest association. After controlling for other factors, having mild lung obstruction was not associated with being diagnosed. PMID- 30294724 TI - Transcriptome-Guided Imaging Genetic Analysis via a Novel Sparse CCA Algorithm. AB - Imaging genetics is an emerging field that studies the influence of genetic variation on brain structure and function. The major task is to examine the association between genetic markers such as single nucleotide polymorphisms (SNPs) and quantitative traits (QTs) extracted from neuroimaging data. Sparse canonical correlation analysis (SCCA) is a bi-multivariate technique used in imaging genetics to identify complex multi-SNP-multi-QT associations. In imaging genetics, genes associated with a phenotype should at least expressed in the phenotypical region. We study the association between the genotype and amyloid imaging data and propose a transcriptome-guided SCCA framework that incorporates the gene expression information into the SCCA criterion. An alternating optimization method is used to solve the formulated problem. Although the problem is not biconcave, a closed-form solution has been found for each subproblem. The results on real data show that using the gene expression data to guide the feature selection facilities the detection of genetic markers that are not only associated with the identified QTs, but also highly expressed there. PMID- 30294725 TI - Non-invasive pulmonary function test on Morquio patients. AB - Morquio patients, in many cases, present with severe tracheal narrowing and restrictive lung problems making them susceptible to high mortality arising from sleep apnea and related complications. Tracheal obstruction with growth imbalance, short neck, adeno and tonsillar hypertrophy, large mandible, and/or pectus carinatum also contributes to the challenges in managing the airway with intubation and extubation due to factors intrinsic to Morquio syndrome. Taken together, these issues lead to serious respiratory distress and life-threatening complications during anesthetic procedures. Furthermore, patients with Morquio syndrome frequently cannot perform standard pulmonary function tests as a result of their distinctive skeletal dysplasia and chest deformity, thus making diagnosis of incipient pulmonary disease difficult. In many cases, conventional spirometry is too difficult for patients to complete, deriving from issues with cooperation or clinical circumstance. Therefore, it is an unmet challenge to assess pulmonary insufficiency with standard pulmonary function test (PFT) with minimal effort. Non-invasive PFT such as respiratory inductance plethysmography, impulse oscillometry system, and pneumotachography were described in Morquio patients as compared with spirometry. Findings from our previous study indicate that these non-invasive tests are a reliable approach to evaluate lung function in a larger range of patients, and provide valuable clinical information otherwise unobtainable from invasive tests. In conclusion, the present study describes the utility of non-invasive (PFT) to accommodate a broad range of patients including intolerance to effort-dependent PFT. PMID- 30294726 TI - Tumor-aware, Adversarial Domain Adaptation from CT to MRI for Lung Cancer Segmentation. AB - We present an adversarial domain adaptation based deep learning approach for automatic tumor segmentation from T2-weighted MRI. Our approach is composed of two steps: (i) a tumor-aware unsupervised cross-domain adaptation (CT to MRI), followed by (ii) semi-supervised tumor segmentation using Unet trained with synthesized and limited number of original MRIs. We introduced a novel target specific loss, called tumor-aware loss, for unsupervised cross-domain adaptation that helps to preserve tumors on synthesized MRIs produced from CT images. In comparison, state-of-the art adversarial networks trained without our tumor-aware loss produced MRIs with ill-preserved or missing tumors. All networks were trained using labeled CT images from 377 patients with non-small cell lung cancer obtained from the Cancer Imaging Archive and unlabeled T2w MRIs from a completely unrelated cohort of 6 patients with pre-treatment and 36 on-treatment scans. Next, we combined 6 labeled pre-treatment MRI scans with the synthesized MRIs to boost tumor segmentation accuracy through semi-supervised learning. Semi supervised training of cycle-GAN produced a segmentation accuracy of 0.66 computed using Dice Score Coefficient (DSC). Our method trained with only synthesized MRIs produced an accuracy of 0.74 while the same method trained in semi-supervised setting produced the best accuracy of 0.80 on test. Our results show that tumor-aware adversarial domain adaptation helps to achieve reasonably accurate cancer segmentation from limited MRI data by leveraging large CT datasets. PMID- 30294727 TI - Image Super-Resolution by Supervised Adaption of Patchwise Self-similarity from High-Resolution Image. AB - Image super-resolution is of great interest in medical imaging field. However, different from natural images studied in computer vision field, the low resolution (LR) medical imaging data is often a stack of high-resolution (HR) 2D slices with large slice thickness. Consequently, the goal of super-resolution for medical imaging data is to reconstruct the missing slice(s) between any two consecutive slices. Since some modalities (e.g., T1-weighted MR image) are often acquired with high-resolution (HR) image, it is intuitive to harness the prior self-similarity information in the HR image for guiding the super-resolution of LR image (e.g., T2-weighted MR image). The conventional way is to find the profile of patchwise self-similarity in the HR image and then use it to reconstruct the missing information at the same location of LR image. However, the local morphological patterns could vary significantly across the LR and HR images, due to the use of different imaging protocols. Therefore, such direct (un supervised) adaption of self-similarity profile from HR image is often not effective in revealing the actual information in the LR image. To this end, we propose to employ the existing image information in the LR image to supervise the estimation of self-similarity profile by requiring it not only being optimal in representing patches in the HR image, but also producing less reconstruction errors for the existing image information in the LR image. Moreover, to make the anatomical structures spatially consistent in the reconstructed image, we simultaneously estimate the self-similarity profiles for a stack of patches across consecutive slices by solving a group sparse patch representation problem. We have evaluated our proposed super-resolution method on both simulated brain MR images and real patient images with multiple sclerosis lesion, achieving promising results with more anatomical details and sharpness.

In response to a stimulus, S1P is produced intracellularly by the action of two sphingosine kinases, and then it is exported to the extracellular environment or acts as an intracellular second messenger. S1P binds to its cognate G-protein coupled receptors, which are known as S1P receptors. There are five S1P receptors that have been identified in vertebrates. By activating S1P receptors, S1P controls a variety of physiological and pathological processes including cell migration, angiogenesis, vascular maturation, inflammation, and invasion, metastasis, and chemoresistance in cancer. S1P has emerged as a critical regulator of leukocyte migration and plays a central role in lymphocyte egress from the thymus and secondary lymphoid organs. In the current review article, we summarize the current understanding of the emigration of lymphocytes and other leukocytes from bone marrow, thymus and secondary lymphoid organs to the circulation, as well as the clinical implications of modulating the activity of the major S1P receptor, S1PR1.

AB - In this paper, we propose a novel multi-atlas based longitudinal label fusion method with temporal sparse representation technique to segment hippocampi at all time points simultaneously. First, we use groupwise longitudinal registration to simultaneously (1) estimate a group-mean image of a subject image sequence and (2) register its all time-point images to the estimated group-mean image consistently over time. Then, by registering all atlases with the group-mean image, we can align all atlases longitudinally consistently to each time point of the subject image sequence. Finally, we propose a longitudinal label fusion method to propagate all atlas labels to the subject image sequence by simultaneously labeling a set of temporally-corresponded voxels with a temporal consistency constraint on sparse representation. Experimental results demonstrate that our proposed method can achieve more accurate and consistent hippocampus segmentation than the state-of-the-art counterpart methods.

In order to be effective, many of the persuasive technologies de-veloped so far relies on user's motivation and ability, which is highly variable and often the reason behind the failure of such technology. In this paper, we present the concept of Mindless Computing, which is a new approach to persuasive technology design. Mindless Computing leverages theories and concepts from psychology and behavioral economics into the design of technologies for behavior change. We show through a systematic review that most of the current persuasive technologies do not utilize the fast and automatic mental processes for behavioral change and there is an opportunity for persuasive technology designers to develop systems that are less reliant on user's motivation and ability. We describe two examples of mindless technologies and present pilot studies with encouraging results. Finally, we discuss design guidelines and considerations for developing this type of persuasive technology.

It has been noted that there is a five-fold increase risk of Myocardial Infarctions (MI) in the first hour after cannabis use. Traditional risk factors for MI include diabetes, hypertension and dyslipidemia. The rising use of cannabis may have ushered in an additional MI risk factor to be added to the list; that is cannabis. In this review, we discuss the growing use of cannabis and potential link with MI, highlighting the common pathogenic hypotheses linking these risk factors. PMID- 30294731 TI - FOXF2 differentially regulates expression of metabolic genes in non-cancerous and cancerous breast epithelial cells. AB - Forkhead box F2 (FOXF2) functions as a transcription factor and is critically involved in programming organogenesis and regulating epithelial-to-mesenchymal transition (EMT) and cell proliferation. We recently have revealed that FOXF2 can exert distinct functional effects on different molecular subtypes of breast cancer. We found that FOXF2 expression is epigenetically silenced in luminal breast cancers due to its tumor-suppressive role in DNA replication regulation. In contrast, FOXF2 is overexpressed in basal-like triple-negative breast cancers (TNBCs) due to its oncogenic role in promoting EMT. Although our and other studies have shown that FOXF2 dysregulation is critical for tumorigenesis of various tissue types, the role of FOXF2 in metabolic rewiring of cancer remains unknown. In this study, we analyzed our previous microarray data to understand the metabolic role of FOXF2 in non-cancerous and cancerous breast epithelial cells. Our studies showed that in non-cancerous breast epithelial cells FOXF2 can also play a dual role either in tumor suppression or in tumor promotion through regulating expression of tumor-suppressive and oncogenic metabolic genes. Furthermore, we found that FOXF2-regulated metabolic genes are not conserved between non-cancerous and cancerous breast epithelial cells and FOXF2 is involved in metabolic rewiring in breast cancer cells. This is the first report to explore the metabolic function of FOXF2 in breast cancer. PMID- 30294732 TI - Constructing multi-interface Mo2C/Co@C nanorods for a microwave response based on a double attenuation mechanism. AB - In this work, novel one-dimensional (1D) Mo2C/Co@C nanorods (MCRs), using a metal organic framework (zeolitic imidazolate framework; ZIF-67) as the coating layer to form multi-interfaces, were formed via a facile hard template method. Compared with previous works relating to porous-carbon-based Mo2C nanocomposites, the well designed MCRs in this study possess a double attenuation mechanism due to the existence of the dielectric materials Mo2C and remaining carbon (RC) and the magnetic compound Co. Thanks to a new design and the multiple useful compounds, the as-prepared MCRs have the features of demonstrating multi-interfacial polarization, a large surface area and highly isotropic dissipation. Hence, the samples not only inherit the excellent microwave absorbing abilities of Mo2C but they also have a broadened effective bandwidth. For example, the minimum reflection loss (RL) value of MCRs with 35% sample loading could reach -47.98 dB. More importantly, RL values of less than -10 dB can be observed from 11.08 to 17.08 GHz (an effective bandwidth of 6.0 GHz) with a matching thickness of 1.6 mm, which is much better than previous work involving porous-carbon-based Mo2C nanocomposites. Firstly, we have reasonably redesigned the samples to have good absorbing properties for practical applications. Secondly, we have paved a highly efficient and universal way to synthesize 1D microwave absorbers with multiple valuable interfaces.

AB - Methyl carbonate ionic liquids are shown to readily mono-deprotonate p-tert butylcalix-[4]-arenes initiating the formation of an organic mono-anionic p-tert butylcalix-[4]-arate salt, methanol and carbon dioxide. These calix-[4]-arate salts have been successfully used in alkylation reactions with dialkyl sulfates and alkyl halides to form a mono-alkylated single product with high yield. This method avoids the common use of alkali metal bases such as caesium fluoride hence providing a safer and more selective synthetic route.

PMID- 30294739 TI - Dual plasmonically tunable slow light based on plasmon-induced transparency in planar graphene ribbon metamaterials. AB - We propose a simulated terahertz design based on planar graphene ribbons. With numerical simulation, we can achieve a very obvious dual plasmon-induced transparency phenomenon through the destructive interference in this structure. Moreover, due to the simple design of this structure and the complete continuous graphene ribbons, the Fermi level of graphene can be regulated by voltage. Thus, the dual plasmon-induced transparency phenomenon can be easily tuned in the numerical simulation. Further structural analysis shows that the two graphene chips on the side of the graphene ribbons play a crucial role in the dual plasmon induced transparency phenomenon. As the length of the two chips is close, the dual plasmon-induced transparency phenomenon gradually becomes a single plasmon induced transparency phenomenon. The theoretical analysis of this structure shows that this system has a very high group index, and its maximum value is 800, which is far greater than that of other types of slow light devices. This work may open up a new way for designing tunable terahertz graphene-based devices and slow light devices. PMID- 30294740 TI - Low temperature reaction dynamics for CH3OH + OH collisions on a new full dimensional potential energy surface. AB - Is the rise of the rate constant measured in laval expansion experiments of OH with organic molecules at low temperatures due to the reaction between the reactants or due to the formation of complexes with the buffer gas? This question has importance for understanding the evolution of prebiotic molecules observed in different astrophysical objects. Among these molecules methanol is one of the most widely observed, and its reaction with OH has been studied by several groups showing a fast increase in the rate constant under 100 K. Transition state theory doesn't reproduce this behavior and here dynamical calculations are performed on a new full dimensional potential energy surface developed for this purpose. The calculated classical reactive cross sections show an increase at low collision energies due to a complex forming mechanism. However, the calculated rate constant at temperatures below 100 K remains lower than the observed one. Quantum effects are likely responsible for the measured behavior at low temperatures.

AB - A thorough analysis of the Cambridge Structure Database reveals that intermolecular pi-hole/n->pi* interactions with carbon monoxide ligands are abundant in the solid state and somewhat directional, particularly with fac-like M(CO)3 fragments (P < 4.0). High level DFT calculations suggest interacting energies up to about -10 kcal mol-1 for adducts of charge neutral complexes.

AB - Oxidation of distorted square-planar perfluoropinacolate Co compound [CoII(pinF)2]2-, 1, to [CoIII(pinF)2]1-, 2, is reported. Rigidly square-planar 2 has an intermediate-spin, S = 1, ground state and very large zero-field splitting (ZFS) with D = 67.2 cm-1; |E| = 18.0 cm-1, (E/D = 0.27), g? = 2.10, g|| = 2.25 and chiTIP = 1950 * 10-6 cm3 mol-1. This Co(iii) species, 2, reacts with ROS to oxidise two (pinF)2- ligands to form tetrahedral [CoII(Hpfa)4]2-, 3. PMID- 30294743 TI - Significant effect of Mg-pressure-controlled annealing: non-stoichiometry and thermoelectric properties of Mg2-deltaSi1-xSbx. AB - Non-stoichiometry related to such an element with high vapor pressure as Mg has been difficult to control, despite its significant influence on the thermoelectric properties of the material. Here, Mg non-stoichiometry and the thermoelectric properties of Mg2-deltaSi1-xSbx (0 <= x <= 0.60) are investigated systematically by tuning the Mg partial pressure during annealing. The range of Mg non-stoichiometry Deltadelta depends on x since the Sb dopant induces Mg vacancies, which are partly filled by Mg atoms in the gas phase according to an equilibrium reaction. The defect association between the Mg vacancies and the Sb dopant decreases Deltadelta at high Sb contents. The maximum Deltadelta of 0.016, which corresponds to a carrier concentration range Deltan of 4.9 * 1020 cm-3, is obtained at x = 0.10. The Seebeck coefficient shows a universal relationship with the carrier concentration, which can be explained by the DFT-calculated band structure within the rigid band approximation. The carrier mobility is reduced significantly as a result of carrier scattering at the Mg-poor grain boundaries. The vacancy formation at the Mg-site, in addition to Si-site substitution for Sb, effectively suppresses the lattice thermal conductivity. The low thermal conductivity on the Mg-poor side increases the maximum zT, while a high energy conversion efficiency is obtained on the Mg-rich side, owing to the high electrical conductivity and resultant large zT at low temperatures. Mg non stoichiometry is a key factor in tuning the thermoelectric properties of Mg2Si based materials and thus its control is essential. PMID- 30294744 TI - Reactivity of the O2+.(H2O)n and NO+.(H2O)n cluster ions in the D-region of the ionosphere. AB - The protonated water clusters present in the D-region of the ionosphere have been postulated to be formed from cluster ions such as O2+.(H2O)n and NO+.(H2O)n, although the detailed mechanism of the underlying reactions is not understood. Second order Moller-Plesset perturbation theory based Born-Oppenheimer ab initio molecular dynamics (AIMD) simulations of the reactions of the O2+.(H2O)n and NO+.(H2O)n cluster ions to form protonated water clusters reveal different mechanisms for the O2+ and NO+ based ions. AIMD simulations of O2+.(H2O)n=2-5 with initial velocities of the atoms sampled from the Maxwell-Boltzmann distribution at 220 K show that following charge transfer, a reaction to form a protonated water cluster and OH occurs rapidly where the neutral O2 molecule is just a spectator. In contrast, the reaction of NO+.(H2O)n=4,5 has been hypothesised to involve an intracluster reaction, but no reaction is observed in AIMD simulations using thermal initial velocities. However, it is shown that reactions to form protonated water clusters do occur in simulations when a water molecule collides with a NO+.(H2O)4 cluster.

AB - Dental pulp stem cells (DPSCs) are adult multipotent stem cells of neuroectodermal origin; they provide an encouraging perspective in the domain of nerve tissue engineering. DPSCs could be transplanted in biodegradable electrospun neuro-supportive scaffold (optimized in various 3D geometries like coating on the surface of titanium implant, hollow/solid tubes, etc.) for enhanced in vivo recovery of peripheral nerves. Herein, we describe the fabrication of uniform bead-free nanofibrous scaffold which supports DPSCs, proliferation, and their subsequent neural differentiation and thus could be utilized for enhanced regeneration of peripheral nervous system. PMID- 30294746 TI - Validation of gallbladder absorbed radiation dose reduction simulation: human dosimetry of [18F]fluortriopride. AB - BACKGROUND: [18F]Fluortriopride (FTP) was developed as a dopamine D3-selective radiotracer, thought to be important to neurobiological reward pathways and implicated in drug addiction, Parkinson's disease, and schizophrenia. Preclinical radiation dosimetry studies found the gallbladder wall received the highest dose. A gallbladder dose reduction intervention was simulated using a novel reduction model for healthy adults following fatty-meal consumption. The goals of this study were to assess whole body FTP human dosimetry and determine the feasibility of reducing absorbed dose to the gallbladder wall. RESULTS: Effective dose without a fatty meal was 0.022 +/- 0.002 mSv/MBq (+/- standard deviation) with highest organ dose of 0.436 +/- 0.178 mSv/MBq to the gallbladder wall (n = 10). Predicted gallbladder dose reduction with fatty meal consumed was 67.4% (n = 10). Meal consumption by four repeat volunteers decreased average gallbladder dose by 71.3% (n = 4) compared to the original ten volunteers. CONCLUSIONS: Observed effective doses were adequately low to continue studying FTP uptake in humans. Validated dosimetry simulations indicate up to a 71% reduction in gallbladder dose can be achieved by employing intrinsic physiology to contract the gallbladder via fatty meal ingestion. This methodology for predicting gallbladder absorbed dose reduction from fatty meal consumption can be applied to other radiopharmaceuticals and radiotherapies. PMID- 30294748 TI - Sphagnum Species Modulate their Phenolic Profiles and Mycorrhizal Colonization of Surrounding Andromeda polifolia along Peatland Microhabitats. AB - Sphagnum mosses mediate long-term carbon accumulation in peatlands. Given their functional role as keystone species, it is important to consider their responses to ecological gradients and environmental changes through the production of phenolics. We compared the extent to which Sphagnum phenolic production was dependent on species, microhabitats and season, and how surrounding dwarf shrubs responded to Sphagnum phenolics. We evaluated the phenolic profiles of aqueous extracts of Sphagnum fallax and Sphagnum magellanicum over a 6-month period in two microhabitats (wet lawns versus dry hummocks) in a French peatland. Phenolic profiles of water-soluble extracts were measured by UHPLC-QTOF-MS. Andromeda polifolia mycorrhizal colonization was quantified by assessing the intensity of global root cortex colonization. Phenolic profiles of both Sphagnum mosses were species-, season- and microhabitat- dependant. Sphagnum-derived acids were the phenolics mostly recovered; relative quantities were 2.5-fold higher in S. fallax than in S. magellanicum. Microtopography and vascular plant cover strongly influenced phenolic profiles, especially for minor metabolites present in low abundance. Higher mycorrhizal colonization of A. polifolia was found in lawns as compared to hummocks. Mycorrhizal abundance, in contrast to environmental parameters, was correlated with production of minor phenolics in S. fallax. Our results highlight the close interaction between mycorrhizae such as those colonizing A. polifolia and the release of Sphagnum phenolic metabolites and suggest that Sphagnum-derived acids and minor phenolics play different roles in this interaction. This work provides new insight into the ecological role of Sphagnum phenolics by proposing a strong association with mycorrhizal colonization of shrubs. PMID- 30294749 TI - Not scene learning, but attentional processing is superior in team sport athletes and action video game players. AB - We tested if high-level athletes or action video game players have superior context learning skills. Incidental context learning was tested in a spatial contextual cueing paradigm. We found comparable contextual cueing of visual search in repeated displays in high-level amateur handball players, dedicated action video game players and normal controls. In contrast, both handball players and action video game players showed faster search than controls, measured as search time per display item, independent of display repetition. Thus, our data do not indicate superior context learning skills in athletes or action video game players. Rather, both groups showed more efficient visual search in abstract displays that were not related to sport-specific situations. PMID- 30294750 TI - Linear-nonlinear-time-warp-poisson models of neural activity. AB - Prominent models of spike trains assume only one source of variability - stochastic (Poisson) spiking - when stimuli and behavior are fixed. However, spike trains may also reflect variability due to internal processes such as planning. For example, we can plan a movement at one point in time and execute it at some arbitrary later time. Neurons involved in planning may thus share an underlying time course that is not precisely locked to the actual movement. Here we combine the standard Linear-Nonlinear-Poisson (LNP) model with Dynamic Time Warping (DTW) to account for shared temporal variability. When applied to recordings from macaque premotor cortex, we find that time warping considerably improves predictions of neural activity. We suggest that such temporal variability is a widespread phenomenon in the brain which should be modeled.

PMID- 30294753 TI - Biodegradation of sulfamethoxazole by a bacterial consortium of Achromobacter denitrificans PR1 and Leucobacter sp. GP. AB - In the last decade, biological degradation and mineralization of antibiotics have been increasingly reported feats of environmental bacteria. The most extensively described example is that of sulfonamides that can be degraded by several members of Actinobacteria and Proteobacteria. Previously, we reported sulfamethoxazole (SMX) degradation and partial mineralization by Achromobacter denitrificans strain PR1, isolated from activated sludge. However, further studies revealed an apparent instability of this metabolic trait in this strain. Here, we investigated this instability and describe the finding of a low-abundance and slow-growing actinobacterium, thriving only in co-culture with strain PR1. This organism, named GP, shared highest 16S rRNA gene sequence similarity (94.6-96.9%) with the type strains of validly described species of the genus Leucobacter. This microbial consortium was found to harbor a homolog to the sulfonamide monooxygenase gene (sadA) also found in other sulfonamide-degrading bacteria. This gene is overexpressed in the presence of the antibiotic, and evidence suggests that it codes for a group D flavin monooxygenase responsible for the ipso-hydroxylation of SMX. Additional side reactions were also detected comprising an NIH shift and a Baeyer-Villiger rearrangement, which indicate an inefficient biological transformation of these antibiotics in the environment. This work contributes to further our knowledge in the degradation of this ubiquitous micropollutant by environmental bacteria. PMID- 30294754 TI - Recent advances in experimental polyphosphazene adjuvants and their mechanisms of action. AB - Vaccination continues to be a very important public health intervention to control infectious diseases in the world. Subunit vaccines are generally poorly immunogenic and require the addition of adjuvants to induce protective immune responses. Despite their critical role in vaccines, adjuvant mechanism of action remains poorly understood, which is a barrier to the development of new, safe and effective vaccines. In the present review, we focus on recent progress in understanding the mechanisms of action of the experimental adjuvants poly[di(carboxylatophenoxy)phosphazene] (PCPP) and poly[di(sodiumcarboxylatoethyl phenoxy)phosphazene] (PCEP) (in this review, adjuvants PCPP and PCEP are collectively referred to as PZ denoting polyphosphazenes). PZs are high molecular weight, water-soluble, synthetic polymers that have been shown to regulate innate immune response genes, induce cytokines and chemokines secretion at the site of injection and, also, induce immune cell recruitment to the site of injection to create a local immune-competent environment. There is an evidence that as well as its role as an immunoadjuvant (that activate innate immune responses), PZ can also act as a vaccine carrier. The mechanism of action that explains how PZ leads to these effects is not known and is a barrier to the development of designer vaccines. PMID- 30294756 TI - Identifying core components and indicators of successful transitions from child to adult mental health services: a scoping review. AB - The aim of this scoping review was to identify the core components of interventions that facilitate successful transition from child and adolescent mental health services to adult mental health services. In the absence of rigorous evaluations of transition program effectiveness for transitioning youth with mental health care needs, these core components can contribute to informed decisions about promising program and intervention strategies. This review examined data from 87 peer-reviewed and non-academic documents to determine the characteristics that support the transition process and to identify opportunities for system and program improvement. Data were extracted and synthesized using a descriptive analytic framework. A major finding of this review is a significant lack of measurable indicators in the academic and gray literature. This review did identify 26 core components organized within the framework of the six core elements of healthcare transitions. Policy makers, practitioners, and administrators can use the core components to guide decisions about transition program and intervention content. Confirmation of the impact of these core program components on youth outcomes awaits the conduct of rigorous randomized trials. Future research also needs to explicitly focus on the development of indicators to evaluate transition programs and interventions.

AB - The urinary tract toxicity is one of the major reasons for investigational drugs not coming into the market and even marketed drugs being restricted or withdrawn. The objective of this investigation is to develop an easily interpretable and practically applicable in silico prediction model of chemical-induced urinary tract toxicity by using naive Bayes classifier. The genetic algorithm was used to select important molecular descriptors related to urinary tract toxicity, and the ECFP-6 fingerprint descriptors were applied to the urinary tract toxic/non-toxic fragments production. The established naive Bayes classifier (NB-2) produced 87.3% overall accuracy of fivefold cross-validation for the training set and 84.2% for the external test set, which can be employed for the chemical-induced urinary tract toxicity assessment. Furthermore, six important molecular descriptors (e.g., number of N atoms, AlogP, molecular weight, number of H acceptors, number of H donors and molecular fractional polar surface area) and toxic and non-toxic fragments were obtained, which would help medicinal chemists interpret the mechanisms of urinary tract toxicity, and even provide theoretical guidance for hit and lead optimization. PMID- 30294755 TI - Combination systemic therapies with immune checkpoint inhibitors in pancreatic cancer: overcoming resistance to single-agent checkpoint blockade. AB - Immune checkpoint inhibitors have demonstrated broad single-agent antitumor activity and a favorable safety profile that render them attractive agents to combine with other systemic anticancer therapies. Pancreatic cancer has been fairly resistant to monotherapy blockade of programmed cell death protein 1 receptor, programmed death ligand 1, and cytotoxic T-lymphocyte associated protein 4. However, there is a growing body of preclinical evidence to support the rational combination of checkpoint inhibitors and various systemic therapies in pancreatic cancer. Furthermore, early clinical evidence has begun to support the feasibility and efficacy of checkpoint inhibitor-based combination therapy in advanced pancreatic cancer. Despite accumulating preclinical and clinical data, there remains several questions as to the optimal dosing and timing of administration of respective agents, toxicity of combination strategies, and mechanisms by which immune resistance to single-agent checkpoint blockade are overcome. Further development of biomarkers is also important in the advancement of combination systemic therapies incorporating checkpoint blockade in pancreatic cancer. Results from an impressive number of ongoing prospective clinical trials are eagerly anticipated and will seek to validate the viability of combination immuno-oncology strategies in pancreatic cancer. PMID- 30294758 TI - Parental Health Spillover in Cost-Effectiveness Analysis: Evidence from Self Harming Adolescents in England. AB - OBJECTIVE: This article presents alternative parental health spillover quantification methods in the context of a randomised controlled trial comparing family therapy with treatment as usual as an intervention for self-harming adolescents, and discusses the practical limitations of those methods. METHODS: The trial followed a sample of 754 participants aged 11-17 years. Health utilities are measured using answers to the EuroQoL 5 Dimensions 3 Levels (EQ-5D 3L) for the adolescent and the Health Utility Index (HUI2) for one parent at baseline, 6 and 12 months. We use regression analyses to evaluate the association between the parent's and adolescent's health utilities as part of an explanatory regression model including health-related and demographic characteristics of both the adolescent and the parent. We then measure cost-effectiveness over a 12-month period as mean incremental cost-effectiveness ratios using various spillover quantification methods. We propose an original quantification based on the use of a household welfare function along with an equivalence scale to generate a health gain within the family to be added to the adolescent's quality-adjusted life-year gain. RESULTS: We find that the parent's health utility increased over the duration of the trial and is significantly and positively associated with adolescent's health utility at 6 and 12 months but not at baseline. When considering the adolescent's health gain only, the incremental cost-effectiveness ratio is L40,453 per quality-adjusted life-year. When including the health spillover to one parent, the incremental cost-effectiveness ratio estimates range from L27,167 per quality-adjusted life-year to L40,838 per quality-adjusted life year and can be a dominated option depending on the quantification method used. CONCLUSION: According to the health spillover quantification method considered, the incremental cost-effectiveness ratios vary from within the National Institute for Health and Care Excellence (NICE) cost-effectiveness threshold range to not being cost-effective. PMID- 30294759 TI - Gut microbiota and Hashimoto's thyroiditis. AB - About two third of the human microbial commensal community, namely the gut microbiota, is hosted by the gastrointestinal tract which represents the largest interface of the organism to the external environment. This microbial community co-evolved in a symbiotic relationship with the human beings. Growing evidence support the notion that the microbiota plays a significant role in maintaining nutritional, metabolic and immunologic homeostasis in the host. Microbiota, beside the expected role in maintaining gastrointestinal homeostasis also exerts metabolic functions in nutrients digestion and absorption, detoxification and vitamins' synthesis. Intestinal microbiota is also key in the correct development of the lymphoid system, 70% of which resides at the intestinal level. Available studies, both in murine models and humans, have shown an altered ratio between the different phyla, which characterize a" normal" gut microbiota, in a number of different disorders including obesity, to which a significant part of the studies on intestinal microbiota has been addressed so far. These variations in gut microbiota composition, known as dysbiosis, has been also described in patients bearing intestinal autoimmune diseases as well as type 1 diabetes mellitus, systemic sclerosis and systemic lupus erythematosus. Being Hashimoto's thyroiditis the most frequent autoimmune disorder worldwide, the analysis of the reciprocal influence with intestinal microbiota gained interest. The whole thyroid peripheral homeostasis may be sensitive to microbiota changes but there is also evidence that the genesis and progression of autoimmune thyroid disorders may be significantly affected from a changing intestinal microbial composition or even from overt dysbiosis. In this brief review, we focused on the main features which characterize the reciprocal influence between microbiota and thyroid autoimmunity described in the most recent literature.

PMID- 30294761 TI - Hopelessness and Delinquent Behavior as Predictors of Community Violence Exposure in Ethnic Minority Male Adolescent Offenders. AB - Justice-involved boys from urban communities are disproportionately impacted by community violence exposure (ECV) and despite decades of research, rates of ECV in youth continue to increase particularly for youth involved in the juvenile justice system. Despite the increased risk of exposure, the majority of research focuses on what may protect youth from the deleterious outcomes associated with violence exposure, rather than strategies that may prevent the violence exposure from occurring. The current study seeks to shift the focus of research in this area to examining factors that may predict future violence exposure. Specifically, the purpose of the current study is to examine the role of hopelessness as a predictor of the risk for violence exposure in a sample of 831 justice-involved, urban boys ages 14-18 (52.2% African American, 42.1% Hispanic, 5.7% other). Results revealed that baseline levels of low aspirations and hopelessness towards the future indirectly predicted violence exposure 1 year later through engagement in delinquent behavior. Clinical implications for targeting youth with elevated risk and preventing future violence exposure are discussed.

AB - The co-adsorption of mixed nonionic surfactant and imidazolium-based ionic liquid, Triton X100 (TX100), with 1-cetyl-3-methylimidazolium bromide (C16mimBr) adsorbed onto the surface of magnetic halloysite nanotubes (MHNTs) was used as an efficient adsorbent for simultaneous determination of amlodipine and nimodipine in urine. The designed adsorbent was characterized by TEM, TGA, FTIR, and DLS analysis methods. All the parameters that influence the extraction efficiency are optimized with the aid of response surface methodology (RSM). The effects of nonionic surfactant TX100 with different structures of ionic-liquid-coated MHNTs were investigated. Under optimum conditions, extraction recoveries of amlodipine and nimodipine were in the range of 73.8-81.2 and 94.3-96.1%, with RSDs (n = 3) of 2.6-5.5% in spiked urine samples, respectively. The adsorption mechanism principal of mixed hemimicelles was discussed in this study. The limit of detection obtained for analytes was < 0.002 MUg.mL-1. To our knowledge, this was the first attempt using a mixed hemimicelle solid-phase extraction (SPE) based on MHNTs and nonionic surfactant and imidazolium-based ionic liquid for the simultaneous determination of amlodipine and nimodipine in biological samples.

AB - Depression is a common disorder in late life that is associated with poor quality of life, increased disability, and increased all-cause mortality. Rates of completed suicide are the highest in older depressed men compared with any other age group. In this age group, depression is often concurrent with medical illness and it can aggravate the course of medical illness. Cognitive impairment is frequently present and may be the result of the depression itself or may be the consequence of a neurodegenerative disorder such as Alzheimer's disease. Evidence based psychotherapies, antidepressants, and somatic treatments such as electroconvulsive therapy are employed in the treatment of older depressed adults. Treatment may be complicated by the presence of cognitive impairment, other comorbid medical disorders, and medications used to treat these disorders. Certain safety issues such as increased bleeding risk, hyponatremia, decreased bone density and falls may be associated with antidepressant treatment, may be more common in older depressed adults, and their consequences may be more severe in late life. These risks, however, need to be weighed against the hazards of untreated depression. With appropriate care, most older depressed patients can be successfully treated and a positive outcome can have a significant effect on the patient's quality of life. PMID- 30294763 TI - Diabetes and HIV. AB - PURPOSE OF REVIEW: This review seeks to address the epidemiology and pathophysiological basis of the interaction between HIV infection and diabetes and the implication for treatment. Its importance stems from the current context of the growing burden of both conditions and the possible mechanisms of interactions that may exist but not yet sufficiently examined. RECENT FINDINGS: HIV infection is associated with increased risk of insulin resistance, and ART is associated with metabolic derangement and the occurrence of type 2 diabetes. The increasing survival among people with HIV infection in developing countries is paralleled by a growing burden of chronic non-communicable diseases (NCDs) especially cardiovascular diseases and diabetes mellitus. The prevalence of diabetes mellitus is higher in HIV-positive persons compared to the general population, and especially those with associated hepatitis C virus (HCV) co infection. Antiretroviral therapy (ART) during chronic HIV infection is the most incriminated risk factor for the development of diabetes mellitus through diverse mechanisms depending on the ART leading to insulin resistance and increased inflammatory status. A staggering 629 million of people 20-79 years are projected to have diabetes by 2045 while the world will soon enter the fourth decade of the HIV infection. Classical risk factors for diabetes such as physical inactivity and unhealthy diet may not solely explain the current trends, suggesting the role of novel risk factors including infections/inflammation. HIV and its treatment have been identified as potential contributors. Co-infections frequently observed during HIV infection also significantly influence both the epidemiological and pathophysiological of the link between HIV and diabetes. Although the relative contribution of each risk factor has not yet been quantified, several lines of evidence suggest that ART is a major contributor to hyperglycemia in HIV infection. ARTs have also led to an increase in metabolic dysfunction, including insulin resistance syndromes, dyslipidemia, and lipodystrophy. The association between ARTs and the risk of developing diabetes therefore calls for a careful choice of medication and evaluation of the risk of developing diabetes. PMID- 30294765 TI - Neurostimulation Therapies. AB - Depression is one of the most disabling conditions in the world. In many cases patients continue to suffer with depressive disorders despite a series of adequate trials of medication and psychotherapy. Neuromodulation treatments offer a qualitatively different modality of treatment that can frequently prove efficacious in these treatment-refractory patients. The field of neuromodulation focuses on the use of electrical/electromagnetic energy, both invasively and noninvasively, to interface with and ultimately alter activity within the human brain for therapeutic purposes. These treatments provide another set of options to offer patients when clinically indicated, and knowledge of their safety, risks and benefits, and appropriate clinical application is essential for modern psychiatrists and other mental health professionals. Although neuromodulation techniques hold tremendous promise, only three such treatments are currently approved by the United States Food and Drug Administration (FDA) for the treatment of major depressive disorder: electroconvulsive therapy (ECT), vagus nerve stimulation (VNS), and repetitive transcranial magnetic stimulation (rTMS). Additionally, numerous other neurostimulation modalities (deep brain stimulation [DBS], magnetic seizure therapy [MST], transcranial electric stimulation [tES], and trigeminal nerve stimulation [TNS]), though currently experimental, show considerable therapeutic promise. Researchers are actively looking for ways to optimize outcomes and clinical benefits by making neuromodulation treatments safer, more efficacious, and more durable. PMID- 30294766 TI - The use of gasoline in a complex suicide. AB - This case represents a planned complex suicide in which the victim shot himself in the head after dousing his living quarters with gasoline. The spark induced ignition of gasoline vapors and led to an explosion. Liquid gasoline is not flammable, but the vapor/mixture of gases above the surface of the liquid is. In this case the victim might have counted on the resulting fire and/or explosion, but we are not able to tell that with certainty. We have assumed that the plan was for the gunshot to the head to lead to instantaneous death, and for the flame and/or explosion to lead to the destruction of the body. The explosion launched the body out of the apartment, meaning it did not get charred. It is also our assumption that the victim did not expect that the explosion would eject his body from the flames and lead to less severe burns than he had calculated, making this complex suicide "less successful" than he had planned. PMID- 30294767 TI - Incidence and costs of injuries to children and adults in the United States. AB - BACKGROUND: Injuries are a leading cause of death and acquired disability, and result in significant medical spending. Prior estimates of injury-related cost have been limited by older data, for certain population, or specific mechanisms. FINDINGS: This study estimated the incidence of hospital-treated nonfatal injuries in the United States (US) in 2013 and the related comprehensive costs. Injury-related emergency department (ED) visits and hospitalizations were identified using 2013 Healthcare Cost and Utilization Project (HCUP) data. Models estimated the costs of medical spending and lost future work due to injuries in 2013 U.S. dollars. A total of 31,038,072 nonfatal injury-related hospitalizations and ED visits were identified, representing 9.8 per 100 people. Hospital-treated nonfatal injuries cost an estimated $1.853 trillion, including $168 billion in medical spending, $223 billion in work losses, and $1.461 trillion in quality of life losses. CONCLUSIONS: Approximately one in 10 individuals in the US is treated in the hospital for injury each year, with high corresponding costs. These data support priority-setting to reduce the injury burden in the US. PMID- 30294768 TI - Gastric Bypass as a Third Bariatric Procedure-Our Experience with 42 Cases. AB - BACKGROUND: It is not uncommon to encounter patients seeking a third, fourth, or even fifth bariatric procedure. With higher expected complication rates and questionable patient benefit, the indication for multiple revisions is still in doubt. To evaluate the perioperative and post-operative outcomes of patients undergoing gastric bypass after two previous bariatric surgeries or more. METHODS: We identified all patients that underwent gastric bypass following at least 2 previous bariatric surgeries. We looked at patient demographics, previous bariatric surgeries, pre-operative body mass index (BMI) and obesity-related co morbidities, perioperative complications, length of stay (LOS), re-admissions and re-operations, percentage of excess weight loss, and resolution or improvement in comorbidities. RESULTS: Forty-two patients met the inclusion criteria, the majority being females (31, 73.8%). Average age was 45.6 years (range 27-62), average weight and BMI was 116 kg (range 75-175 kg) and 41.1 kg/m2 (range 25.6 58.7 kg/m2), respectively. Thirty-two patients had two previous bariatric surgeries (73.8%), and 10 patients had 3 former bariatric surgeries (23.8%), and for one patient, this was the fifth bariatric procedure (2.4%). Mean LOS was 10 days (range 2-56 days). Eight patients (19%) needed re-admission and 5 (11.9%) needed re-operation. At a median follow up of 48 months (range 7-99 months), the average BMI was 34.5 kg/m2 (range 23.7-55.1 kg/m2) reflecting an excess BMI loss of 43.3%. CONCLUSIONS: Gastric bypass as a third or more bariatric procedure is effective yet associated with high complication rates, re-admissions, and re operations. PMID- 30294769 TI - The inflection point: a torque reference for lingual bracket positioning on the palatal surface curvature of the maxillary central incisor. AB - BACKGROUND: Contrary to buccal orthodontics, lingual orthodontics has no reference for vertical bracket positioning on the maxillary central incisor. The aim of this study was to provide a reference point in relation to torque for lingual bracket positioning on the palatal surface curvature (PSC) of the maxillary central incisor. METHODS: Cone beam computed tomography (CBCT) radiographs of 50 right maxillary central incisors from archives of a dental radiographic center were transferred to Photoshop, where their PSC was traced using pen-tool. The PSC torque angle values of the incisors were calculated in Excel using cubic poly-Bezier curves at 0.5-mm increments and at the inflection point of PSC. Descriptive statistics for the torque angle values of the increments and for the inflection point for the 50 incisors were then calculated. One-way ANOVA test was used to detect systematic differences between the increments, and Tukey test was used post-hoc. RESULTS: For all incisors, increments incisal to inflection point exhibited progressive decrease in torque angle values from the first-calculated increment to inflection point while increments cervical to inflection point exhibited progressive increase from inflection point to last-calculated increment. Mean torque angle values of all the increments and inflection point showed high standard deviations and vast range of values. One-way ANOVA test was highly statistically significant (p < 0.0001) and most pairwise comparisons of the increments using Tukey test were significant. CONCLUSIONS: Inflection point can be used as a reference for bracket positioning on PSC. Cervically oriented shifts in vertical bracket position cause crown labial/root palatal movement cervical to inflection point and crown palatal/root labial movement incisal to it. A scientific mathematical justification for customized bracket torque prescriptions on PSC of maxillary central incisor was also provided. PMID- 30294770 TI - Correction to: Jeger V, et al. Is there a role for procalcitonin in differentiating uncomplicated and complicated diverticulitis in order to reduce antibiotic therapy? PMID- 30294771 TI - Effects of maternal caffeine consumption on the breastfed child: a systematic review. AB - BACKGROUND: Nutrition in the first 1000 days between pregnancy and 24 months of life is critical for child health, and exclusive breastfeeding is promoted as the infant's best source of nutrition in the first 6 months. Caffeine is a central nervous system stimulant occurring naturally in some foods and used to treat primary apnoea in premature babies. However high caffeine intake can be harmful, and caffeine is transmitted into breastmilk. AIM: To systematically review the evidence on the effects of maternal caffeine consumption during breastfeeding on the breastfed child. METHOD: A systematic search was conducted to October 2017 in MEDLINE, EMBASE, Web of Science, CINAHL, and Cochrane Library. The British Library catalogue, which covers doctoral theses, was searched and PRISMA guidelines followed. Two reviewers screened for experimental, cohort, or case control studies and performed independent quality assessment using the Newcastle Ottawa scale. The main reviewer performed data extraction, checked by the second reviewer. RESULTS: Two cohort, two crossover studies, and one N-of-1 trial were included for narrative synthesis. One crossover and two cohort studies of small sample sizes directly investigated maternal caffeine consumption. No significant effects on 24-hour heart rate, 24-hour sleep time, or frequent night waking of the breastfed child were found. One study found a decreased rate of full breastfeeding at 6 months postpartum. Two studies indirectly investigated caffeine exposure. Maternal chocolate and coffee consumption was associated with increased infant colic, and severe to moderate exacerbation of infant atopic dermatitis. However, whether caffeine was the causal ingredient is questionable. The insufficient and inconsistent evidence available had quality issues impeding conclusions on the effects of maternal caffeine consumption on the breastfed child. CONCLUSION: Evidence for recommendations on caffeine intake for breastfeeding women is scant, of limited quality and inconclusive. Birth cohort studies investigating the potential positive and negative effects of various levels of maternal caffeine consumption on the breastfed child and breastfeeding mother could improve the knowledge base and allow evidence-based advice for breastfeeding mothers.

PMID- 30294773 TI - The immune influence of a parabiosis model on tumour-bearing mice. AB - AIM: The aim of this study was to analyse the immune influence of a parabiosis model on tumour-bearing mice. METHODS: Parabiosis was established between C57BL/6 wild-type mice expressing green fluorescent protein (GFP+) and C57BL/6 wild-type mice without green fluorescent protein (GFP?) to ensure blood cross-circulation between animals, and then the expression of CD4+ T cells, CD8+ T cells and interleukins 2, 4 and 10, and interferon-gamma (INF-gamma) in spleen cells of parabiosis model mice were examined with flow cytometry. At day 8 and day 14 after conjoined surgery, we were aiming to sample tumour tissue in the parabiosis mice and observe changes of CD3, CD4, CD8, CD31, IFN-gamma and vascular endothelial growth factor (VEGF) through immunohistochemical analysis. RESULTS: The interaction of blood was established on the third day with modelling rate of 85.7% after blood interaction. The healthy cells of GFP+ C57 mice entered the blood circulation of tumour-bearing mice via a connecting capillary network, playing a role in stimulating CD4+ and CD8+ cells in the tumour-bearing mice so that CD4+ cells increased more in tumour-bearing mice than in the positive control group (p <0.05). The number of GFP+ cells that were detected in a tumour bearing mouse was small, but GFP+ cells can stimulate the mouse itself to generate more CD4+/interleukin (IL)-4, CD4+/IL-10 (p <0.05).The numbers of CD4+/IL-2, CD4+/IL-4 and CD4+/IL-10 among the GFP+ mice were higher than those in the negative control group(p <0.05).The levels of IFN-gamma in both mice in the parabiosis model were decreased (p <0.05). The rate of CD4+/CD8+ in parabiosis GFP+ mice was higher than in the negative control group (p <0.05). In immunohistochemical tests, the rates of CD3, CD4, CD8 and IFN-gamma positive cells was higher than in the positive control group, with their optical densities of 0.32 +/- 0.63, 0.33 +/- 0.00, 0.31 +/- 0.91 and 0.28 +/- 0.14 respectively (p <0.05). The expression of CD31 (0.19 +/- 0.50) and VEGF (0.19 +/- 0.21) were lower when compared with the positive control group, with no significant difference. CD31 and VEFG cell expression was low, at 0.19 +/- 0.50 and 0.19 +/- 0.21, respectively, compared with the positive control group (p >0.05). Values for CD31 and VEGF cells in the positive control group were higher, at 0.32 +/- 0.35 and 0.29 +/- 0.35, respectively, but when compared with the parabiosis tumour-bearing group, there was no significant difference. The expression of CD3, CD4, CD8 and IFN-gamma cells at day 8 was low: 0.22, 0.17, 0.15 and 0.16, respectively. When compared with the parabiosis tumour-bearing group, there was no significant difference. CONCLUSIONS: The established allogeneic parabiosis mice model can be well adapted to the conjoined state of mice and be applied in wide medical experiments. The parabiosis model has played an important role in studying immune regulation, which provides a basis for the future tumour immunotherapy. Parabiosis models can stimulate tumour-bearing mice to generate CD3, CD4, CD8 and IFN-gamma, and play a notable role in immune regulation and tumour destruction. The positive expression rates of CD31 and VEFG cells in the parabiosis tumour-bearing group were lower; however, when compared with the positive control group, there was no significant difference. PMID- 30294774 TI - Semispecific TPPII inhibitor Ala-Ala-Phe-chloromethylketone (AAF-cmk) displays cytotoxic activity by induction of apoptosis, autophagy and protein aggregation in U937 cells. AB - INTRODUCTION: The main component of extralysosomal proteolysis is the ubiquitin proteasome system (UPS), which is supplemented by tripeptidyl peptidase II (TPPII). That system is a target for anticancer strategies by using proteasome inhibitors. Data from several studies on leukemic cells share evidence for the beneficial and potential role of TPPII in cell survivability. Therefore, the aim of this work was to analyze the effect of AAF-cmk, a membrane permeable semi specific TPPII inhibitor, on human monocytic leukemic cells U937 for translational research. MATERIAL AND METHODS: We studied the viability of U937 cells incubated with AAF-cmk using tetrazolium salt reduction assay (MTT) and apoptosis induction by assessing caspase activation by Western blotting and Annexin V binding assays. Transmission electron microscopy (TEM), a gold standard for apoptosis and autophagy detection, was used to assess the ultrastructure of U937 cells. RESULTS: Incubation of cells with AAF-cmk reduced their viability and induced apoptosis by intrinsic pathway. In groups treated with AAF-cmk, activation of caspases 9 and 3 was observed and caspase inhibition by zVDA restored cell viability. TEM revealed the presence of ultrastructural features of apoptosis. Moreover, we identified two types of protein aggregates. The first one was found in close proximity to the endoplasmic reticulum (ER) and corresponds to Aggresome-Like Structure (ALIS); however, the second novel type of aggregate was not related to ER-elements, but rather to free cytosolic ribosomes. This type did not correspond to the aggresome neither in localization nor the structure, thus we referred these aggregates as ALiSNER (Aggresome-Like Structure Not Associated with the ER). CONCLUSIONS: Our results provide novel and important findings about the role of TPPII in protein homeostasis and cell survival. Since semispecific TPPII inhibitor AAF-cmk displays cytotoxic activity against leukemic U937 cells in vitro it can be considered as a potential anticancer agent.

PMID- 30294776 TI - Self-care and manual ability in preschool children with cerebral palsy: a longitudinal study. AB - AIM: To describe longitudinal development of self-care and its relationship to manual ability in children with cerebral palsy (CP) aged 18 months to 5 years across all functional abilities. METHOD: This was a prospective longitudinal population-based study of 290 children with CP (178 [61%] males, 112 [39%] females). Self-care was assessed using the Pediatric Evaluation of Disability Inventory (PEDI). At 60 months (n=242), children were classified using the Manual Ability Classification System (MACS); 113 in level I (47%), 61 in MACS level II (25%), 24 in MACS level III (10%), 14 in MACS level IV (6%), and 30 in MACS level V (12%). Measures were taken at 18 months, 24 months, 30 months, 36 months, 48 months, and 60 months of age. Longitudinal analyses were performed using mixed effects linear regression models. RESULTS: Self-care development achieved by 60 months was negatively associated with the severity of manual ability impairment. Distinct self-care developmental trajectories were found with estimated changes in PEDI self-care scaled scores per month: 0.61 for MACS level I, 0.46 for MACS levels II, 0.31 for MACS level III, 0.16 for MACS level IV, and 0.03 for MACS level V. Children classified in MACS level V had the lowest level of self-care skills at 18 months and showed no progress in self-care development. INTERPRETATION: This study reports rate of self-care development in preschool children with CP. Self-care performance was highest in children with greatest manual ability. Clinicians may use rates of change to predict or monitor self care performance. PEDI trajectories inform goal setting in discussions with families regarding expected levels of independence in self-care. WHAT THIS PAPER ADDS: Distinct self-care developmental trajectories in children with cerebral palsy were found according to Manual Ability Classification System (MACS) levels. Children in MACS levels IV and V with epilepsy did not show any significant change in self-care. Children in MACS levels IV and V without epilepsy demonstrated small yet significant gains in self-care performance.

AB - OBJECTIVE: To evaluate the effect of partisan political control on financial performance, structure, and outcomes of for-profit and not-for-profit US nursing homes. DATA SOURCES/STUDY SETTING: Nineteen-year panel (1996-2014) of state election outcomes, financial performance data from nursing home cost reports, operational and aggregate resident characteristics from OSCAR of 13 737 nursing homes. STUDY DESIGN: A linear panel model was estimated to identify the effect of Democratic and Republican political control on next year's outcomes. Nursing home outcomes were defined as yearly facility revenues, expenses, and profits; the number of Medicaid, Medicare, and private-pay residents; staffing levels; and selected resident outcomes. PRINCIPAL FINDINGS: Democratic political control leads to an increase in financial flows to for-profit nursing homes, boosting profits without producing observable improvements in resident outcomes. Republican political control leads to lower revenues and profits of for-profit nursing homes. A shift from Medicaid to more profitable private-pay residents following Republican political control is observed for all nursing homes. Financial performance of not-for-profit nursing homes is not significantly affected by changes in political control. CONCLUSION: Political control of the two legislative chambers-but not of the governorship-shapes the structure of the nursing home industry as seen in provider behavior.

PMID- 30294783 TI - Family-centred health care for children with cerebral palsy. AB - AIM: To identify characteristics of young children with cerebral palsy (CP), and intrinsic and extrinsic factors, that may be associated with parental perceptions regarding family-centred health care services. METHOD: We conducted a cross sectional study, drawing our sample from the Canadian Cerebral Palsy Registry (CCPR). Parents rated the extent of family-centred care provided by their child's health care teams using the 56-item Measures of Process of Care (MPOC) questionnaire. Environmental and CP phenotypic variables were extracted from the CCPR for group comparisons. Low and high MPOC-56 raters were also compared. RESULTS: Valid responses were obtained from 282 families (90%). All MPOC-56 subscales were highly rated (median >=6.0), indicating satisfaction with health care services, with the exception of the Providing General Information subscale (median 4.8, interquartile range 3.2-6.0). Parents from Nova Scotia rated all subscales significantly higher than parents from other regions. CP subtype and severity were not significantly associated with MPOC-56 subscale scores. Higher socio-economic status was associated with lower MPOC-56 subscale scores. Higher paternal educational attainment and household income were significantly associated with lower scores on the Providing General Information and Providing Specific Information about the Child subscales respectively. INTERPRETATION: Participants affirmed the provision of family-centred services from Canadian pediatric rehabilitation centres. Sociodemographic factors were associated with parental perceptions of family-centred services. WHAT THIS PAPER ADDS: Sociodemographic factors were associated with parental perceptions of family centred care. Factors intrinsic to the child's cerebral palsy were not associated with parental perceptions. PMID- 30294784 TI - Rehospitalizations for complications and mortality following pacemaker implantation: A retrospective cohort study in an older population. AB - INTRODUCTION: A large number of older people receive pacemakers each year but broad population-based studies that describe complications following pacemaker implantation in this population are lacking. METHODS: We conducted a retrospective cohort study using data from the Australian Government Department of Veterans' Affairs database. The cohort consisted of patients who received a pacemaker from 2005 to 2014. The outcomes were subsequent rehospitalizations for infections, procedure-related complications, thromboembolism, cardiovascular events (heart failure, myocardial infarction, and atrial fibrillation), and reoperation of pacemaker, and mortality. RESULTS: There were 10 883 pacemakers recipients, the median age was 86 years (interquartile range 83-89), 61% were males, and 74% received a dual-chamber pacemaker. Within 90 days postdischarge, rehospitalizations were occasioned by pacemaker infection in 0.5%, device-related complications in 1.5%, cerebral infarction in 0.7%, and heart failure in 6% of single-chamber pacemaker recipients. In dual-chamber pacemaker recipients rehospitalizations were occasioned by pacemaker infection in 0.4%, septicemia in 0.4%, device-related complications in 1.2%, cerebral infarction in 0.3%, and heart failure in 3%. Rehospitalizations for pacemaker adjustment occurred in 1.5% of patients. The 90-day postdischarge mortality was 5% and 3% in patients with single- and dual-chamber pacemaker, respectively. CONCLUSION: Rehospitalizations for infection, procedure-related complications, or thromboembolism occurred in 1% to 2% of patients within 90 days postdischarge, while 10% of single chamber and 7% of dual-chamber recipients experienced a rehospitalization for a cardiovascular event. PMID- 30294785 TI - Serological and genetic characterization of Flavobacterium psychrophilum isolated from farmed salmonids in Turkey. AB - Turkey was the largest rainbow trout producer of the European countries in 2016, and the reason for this production is mainly attributed to its egg and fry production. Flavobacterium psychrophilum cause the highest rates of mortality in the starting to feeding stages of the fish. In the present study, twenty-five F. psychrophilum isolates recovered from rainbow trout, coruh trout and brook trout were analysed by RAPD-PCR, ERIC-PCR, REP-PCR and PCR-RFLP, including 16S rRNA, gyrA and gyrB gene regions and PCR-based serotyping method. The PCR-based molecular analysis showed that the isolates could not be differentiated exactly according to isolation source and geographical region. Most isolates were of type 1 and type-2, and some of them were of type-0 and type-3; in addition, one isolate showed a unique serotype. The combined analysis results showed that F. psychrophilum isolates discriminated as five different genotypes and all isolates were successfully discriminated based on host. PMID- 30294786 TI - International validation of harmonized definitions for complications of blood donations. AB - BACKGROUND: In December 2014, a multinational collaboration of hemovigilance experts from the International Society of Blood Transfusion (ISBT), the International Hemovigilance Network, and AABB published harmonized definitions of complications related to blood donation titled "Standard for Surveillance of Complications Related to Blood Donation." Both mandatory and optional terms were included. The definitions are endorsed by the Alliance of Blood Operators and the European Blood Alliance. STUDY DESIGN AND METHODS: The objective of this study was to validate harmonized donor hemovigilance definitions with potential users. In June 2016, 30 real-world cases were sent to potential users around the world along with the definitions, an answer sheet, and instructions on how to complete the validation exercise. RESULTS: Overall, 54 responses from 25 countries were received, including over 400 comments. The results were presented for feedback at both ISBT and AABB meetings. Case diagnoses were consistent across most responders. Exceptions were rare adverse events, nonstandard presentations, or incomplete information. In general, the application of optional definitions, including severity grading and imputability, had the most variability. CONCLUSION: The use of standardized terms in the donor setting serves to increase focus on donor safety, facilitate conversation, foster exchange of information, and frame questions for future research. Overall, the definitions provide adequate coverage of donor reactions; however, some terms require clarification. Severity grading and imputability and other optional terms need clear and objective definitions and instructions on when and how to use them. Additional feedback and final recommendations are summarized in this report. PMID- 30294787 TI - Segmental morphometrics of bonobos (Pan paniscus): are they really different from chimpanzees (Pan troglodytes)? AB - The inertial properties of body segments reflect performance and locomotor habits in primates. While Pan paniscus is generally described as more gracile, lighter in body mass, and as having relatively longer and heavier hindlimbs than Pan troglodytes, both species exhibit very similar patterns of (quadrupedal and bipedal) kinematics, but show slightly different locomotor repertoires. We used a geometric model to estimate the inertial properties for all body segments (i.e. head, trunk, upper and lower arms, hand, thigh, shank and foot) using external length and diameter measurements of 12 anaesthetized bonobos (eight adults and four immatures). We also calculated whole limb inertial properties. When we compared absolute and relative segment morphometric and inertial variables between bonobos and chimpanzees, we found that adult bonobos are significantly lighter than adult chimpanzees. The bonobo is also shorter in head length, upper and lower arm lengths, and foot length, and is generally lighter in most absolute segment mass values (except head and hand). In contrast, the bonobo has a longer trunk. When scaled relative to body mass, most differences disappear between the two species. Only the longer trunk and the shorter head of the bonobo remain apparent, as well as the lighter thigh compared with the chimpanzee. We found similar values of natural pendular periods of the limbs in both species, despite differences in absolute limb lengths, masses, mass centres (for the hindlimb) and moments of inertia. While our data contradict the commonly accepted view that bonobos have relatively longer and heavier hindlimbs than chimpanzees, they are consistent with the observed similarities in the quadrupedal and bipedal kinematics between these species. The morphological differences between both species are more subtle than those previously described from postcranial osteological materials. PMID- 30294788 TI - Post-metamorphic ontogeny of Zoroaster fulgens Thomson, 1873 (Asteroidea, Forcipulatacea). AB - The complete ontogenetic development of an asteroid skeleton has never been described formally for any species. Here, we describe in detail the post metamorphic ontogeny of Zoroaster fulgens Thomson, 1873. The major novelty of our work is the description of patterns of plate addition, the ontogeny of the internal ossicles, as well as the variability of ossicles according to their position along series. Seven specimens collected in the Rockall Basin (North Atlantic) were dissected with bleach and their anatomy was documented using a scanning electron microscope. The external anatomy was additionally observed on more than 30 specimens. We found that the overall structure of the skeleton does not change much between juveniles and adults, but the shape of individual ossicle changes during growth. Allometric scaling was particularly visible on the orals, ambulacrals and adambulacrals. The shape of an ossicle is more dependent of its position along the arm series than of its individual size. Many morphological features differentiate progressively during ontogeny, while others are expressed consistently among specimens. The study of this ontogenetic series allows discussing the homology between the structures present on the ossicles of Z. fulgens in particular and other forcipulatacean sea stars in general (i.e. muscles insertions and articulation areas). The new data obtained in this study provide a comprehensive framework of the anatomy and ontogeny of Z. fulgens that will help resolve taxonomic and phylogenetic controversies in the future. PMID- 30294790 TI - Comparison of short-term complications between unilateral and single-session bilateral surgery for medial patellar luxation in small/medium breed dogs. AB - OBJECTIVES: To compare the short-term complications of unilateral versus single session bilateral medial patellar luxation surgery in small dogs. MATERIALS AND METHODS: The medical records of dogs weighing less than 13?6 kg that underwent medial patellar luxation surgery were reviewed. Dogs were included in one of two groups based on the type of surgery performed (unilateral or single-session bilateral). Postoperative patellar luxation grade and complications were compared between the groups. RESULTS: Two hundred and fifty-one dogs were included. In the bilateral treatment group, there was less improvement in patellar luxation grade and postoperative medial patellar luxation grade was higher. The frequency of major complications was higher in the bilateral group (23%) compared with the unilateral group (12%). CLINICAL SIGNIFICANCE: Single-session bilateral medial patellar luxation surgery was associated with a higher complication rate compared to unilateral surgery in this non-randomized observational study. Staged rather than single-session bilateral surgery should be considered in dogs with bilateral medial patellar luxation to improve clinical outcome and reduce the chance of major complications.

AB - Subdivision of cloaca into urogenital and anorectal passages has remained controversial because of disagreements about the identity and role of the septum developing between both passages. This study aimed to clarify the development of the cloaca using a quantitative 3D morphological approach in human embryos of 4 10 post-fertilisation weeks. Embryos were visualised with Amira 3D-reconstruction and Cinema 4D-remodelling software. Distances between landmarks were computed with Amira3D software. Our main finding was a pronounced difference in growth between rapidly expanding central and ventral parts, and slowly or non-growing cranial and dorsal parts. The entrance of the Wolffian duct into the cloaca proved a stable landmark that remained linked to the position of vertebra S3. Suppressed growth in the cranial cloaca resulted in an apparent craniodorsal migration of the entrance of the Wolffian duct, while suppressed growth in the dorsal cloaca changed the entrance of the hindgut from cranial to dorsal on the cloaca. Transformation of this 'end-to-end' into an 'end-to-side' junction produced temporary 'lateral (Rathke's) folds'. The persistent difference in dorsoventral growth straightened the embryonic caudal body axis and concomitantly extended the frontally oriented 'urorectal (Tourneux's) septum' caudally between the ventral urogenital and dorsal anorectal parts of the cloaca. The dorsoventral growth difference also divided the cloacal membrane into a well-developed ventral urethral plate and a thin dorsal cloacal membrane proper, which ruptured at 6.5 weeks. The expansion of the pericloacal mesenchyme followed the dorsoventral growth difference and produced the genital tubercle. Dysregulation of dorsal cloacal development is probably an important cause of anorectal malformations: too little regressive development may result in anorectal agenesis, and too much regression in stenosis or atresia of the remaining part of the dorsal cloaca. PMID- 30294792 TI - Systematic review with meta-analysis: the efficacy of prebiotics, probiotics, synbiotics and antibiotics in irritable bowel syndrome. AB - BACKGROUND: Irritable bowel syndrome (IBS) is a chronic functional bowel disorder. Disturbances in the gastrointestinal microbiome may be involved in its aetiology. AIM: To perform a systematic review and meta-analysis to examine the efficacy of prebiotics, probiotics, synbiotics and antibiotics in IBS. METHODS: MEDLINE, EMBASE, and the Cochrane Controlled Trials Register were searched (up to July 2017). Randomised controlled trials (RCTs) recruiting adults with IBS, comparing prebiotics, probiotics, synbiotics or antibiotics with placebo or no therapy were eligible. Dichotomous symptom data were pooled to obtain a relative risk (RR) of remaining symptomatic after therapy, with a 95% confidence interval (CI). Continuous data were pooled using a standardised mean difference with a 95% CI. RESULTS: The search identified 4017 citations. Data for prebiotics and synbiotics were sparse. Fifty-three RCTs of probiotics, involving 5545 patients, were eligible. Particular combinations of probiotics, or specific species and strains, appeared to have beneficial effects on global IBS symptoms and abdominal pain, but it was not possible to draw definitive conclusions about their efficacy. There were five trials of similar design that used rifaximin in non constipated IBS patients, which was more effective than placebo (RR of symptoms persisting = 0.84; 95% CI 0.79-0.90). Adverse events were no more common with probiotics or antibiotics. CONCLUSIONS: Which particular combination, species or strains of probiotics are effective for IBS remains, for the most part, unclear. Rifaximin has modest efficacy in improving symptoms in non-constipated IBS. PMID- 30294793 TI - Asymptomatic solitary mass on the sacral region. AB - Nuchal-type fibroma (NTF) is a rare, benign, tumour-like fibrous proliferation of unknown pathogenesis. Despite the name, approximately one-third of cases occur at extranuchal sites. We report a rare case of NTF of the sacral region, an extremely uncommon extranuchal site. As NTF is often misdiagnosed because of its rarity and histopathological similarity with other fibrous tumours, we present this case to increase understanding of this rare disease entity. PMID- 30294794 TI - Invasion and migration of MDA-MB-231 cells are inhibited by block of AhR and NFAT: role of AhR/NFAT1/beta4 integrin signaling. AB - Benzo[alpha]pyrene (BaP) can have significant role in the development of breast cancer via aryl hydrocarbon receptor (AhR) activation. AhR activation has been studied in several functions such as survival, migration and invasion of cancer cells. In cancer, integrins contribute to the migration/invasion process and are regulated by nuclear factor of activated T cells (NFAT) and transforming growth factor (TGF) beta pathways. The aim of the present study was to examine the effect of BaP, an activator of AhR and cyclosporine A (CsA), as inhibitor of NFAT on migration and invasion of MDA-MB-231 cells. Furthermore, the effects of BaP and CsA were evaluated regarding the crosstalk of AhR, NFAT1 and TGF-beta receptor 1 signaling. Treatment of MDA-MB-231 with BaP resulted in significantly more live cells in low doses; however, blocking NFAT with CsA decreased the viability of the cells. Activation of AhR by BaP induced invasion as well as migration in MDA-MB-231 cells, which was blocked by AhR antagonist. Unlike BaP, block of NFAT with CsA inhibited cell migration and cell invasion. In these cells, BaP significantly reduced AhR expression while this reduction was reversed by CH-223191; however, CsA treatment lowered the AhR expression only at low dose. The level of beta4 integrin was significantly reduced by CsA at 1 and 2.5 MUm. Protein levels of Snail and TGF-beta receptor 1 were not significantly altered by BaP and CsA treatments. Considering these findings, the low AhR expression and high beta4 integrin level following BaP and/or CsA treatments may contribute to the higher invasion/migration in MDA-MB-231 cells. PMID- 30294795 TI - A Potential Pitfall of Using Focused Assessment With Sonography for Trauma in Pediatric Trauma. AB - Prospective studies have shown sensitivities of 73% to 88% and specificities of 98% to 100% for using the focused assessment with sonography for trauma (FAST) examination to identify free fluid in adult trauma patients. However, the efficacy of FAST examinations for pediatric trauma patients has not been well defined, and studies looking at diagnostic performance have had varied results. We describe 3 cases of the potential pitfalls of the pediatric FAST examination in pediatric trauma patients using an advanced-processing ultrasound machine. We hypothesize several etiologies for these false-positive findings in the setting of advanced image-processing capabilities of point-of-care ultrasound. We also discuss the reevaluation of clinical algorithms and interpretation practices when using the FAST examination in pediatric trauma. PMID- 30294796 TI - Proteomic fingerprinting of apple fruit, juice, and cider via combinatorial peptide ligand libraries and MS analysis. AB - Combinatorial peptide ligand libraries coupled to MS was applied to extensively map the proteome of apple fruit, and to detect its presence in commercial apple juice and cider to evaluate their authenticity and genuineness. Using the Uniprot_Malus database, 96 proteins were detected in apples, among which 30 proteins were specifically captured via combinatorial peptide ligand libraries. Next, three proteins, previously recognized in fruits, were found in apple juice, which were involved in cellular metabolism of fruit maturation and in allergenic reactions. On the other hand, only one Malus allergen was identified in cider beads eluate, demonstrating that the industrial processes did not prevent any negative effects in sensitive subjects. Thus, the present study not only increases the knowledge of the apple proteome but also offers a reliable analytical method to assess quality and genuineness of commercial products, which could be also used to inform consumers about the presence of allergens. PMID- 30294797 TI - A method for quantitative 2-dimensional sonographic analysis of the fetal conus medullaris position. AB - OBJECTIVE: This study explored the use of 2-dimensional (2D) ultrasound scans for the quantitative assessment of the fetal conus medullaris (CM) position and its correlation with gestational age (GA). METHODS: This was a prospective study. We identified the first sacral vertebra (S1) by intersection of 2 lines in 2D scans, then counted upward from S1 to determine the CM level and recorded the number of ossified sacral vertebral bodies. A quantitative assessment of the CM position was performed by measuring the distance between the CM and the midpoint of the S1 (CM-S1). The correlation between the CM-S1 distance and GA was evaluated. RESULTS: We determined the CM level by identifying S1 first in 521 fetuses (GA, 20-38 weeks). The CM position in 70% of cases was at the L2 and L2-3 level, and at the L2 level or above after 37 weeks. The number of ossified sacral veterbral bodies was not consistent. CM-S1 measurements were easy to perform. A significant positive correlation between CM-S1 distance and GA was observed (R2 = .89, P < .05). The best-fit formula was: CM-S1 distance = 1.57 * GA - 16.43. The normal reference range was established and the fifth percentile was calculated for each GA. CONCLUSIONS: S1 was easily identified, and the CM position relative to S1 was useful. There was a substantial correlation between CM-S1 and GA. Below the fifth percentile it was suggested that tethered cord may exist. PMID- 30294798 TI - Chronic exposure to perfluorononanoic acid impairs spermatogenesis, steroidogenesis and fertility in male mice. AB - Perfluoroalkyl acids (PFAAs) are widely used in commercial applications and that they are ubiquitous and persistent in the environment. Perfluorononanoic acid (PFNA), a member of PFAAs, has been detected in human and wildlife. Previous acute exposure studies have shown the adverse effect of PFNA on the testis. The present study was aimed to examine the effect of chronic PFNA exposure, from prepuberty to adulthood, on testicular functions and fertility in Parkes (P) male mice and to investigate the possible mechanism(s) of its action. PFNA (0.2 and 0.5 mg/kg) was orally administered to P male mice for 90 days from prepuberty (postnatal day [PND] 25) to adulthood (PND 114). Histologically, testes in PFNA treated mice showed non-uniform degenerative changes in the seminiferous tubules. The treatment also had adverse effects on testicular expression of steroidogenic markers, serum levels of cholesterol and testosterone, sperm parameters and on litter size. A marked increase in the level of lipid peroxidation and decrease in the activities of antioxidant enzymes were observed in the testis of PFNA-treated mice compared to controls. Further, a significant decrease in expression of proliferating cell nuclear antigen (PCNA) and in the number of PCNA-positive cells, and an increase in expression of caspase-3 were also noted in PFNA-treated mice testis. In conclusion, the results suggest that chronic exposure to PFNA in male mice interferes with testosterone biosynthesis and causes oxidative stress in the testis, leading to alterations in spermatogenesis, sperm quality and fertility potential. PMID- 30294799 TI - Long non-coding MEG3 is a marker for skeletal muscle development and meat production traits in pigs. AB - Long non-coding RNAmaternally expressed gene 3 (lncRNAMEG3) plays an important role in mammalian muscle development. Our previous transcriptome study showed that lncRNAMEG3 is differentially expressed during postnatal skeletal muscle development in pigs. The objective of the present study was to analyse the role of lncRNAMEG3 in prenatal and postnatal skeletal muscle development and investigate the association of MEG3 with meat production traits in pigs. We investigated the sequence conservation and temporal-spatial expression of lncRNAMEG3 and identified its core promoter and single nucleotide polymorphisms (SNPs). Our results show that MEG3 is conserved among pig, human and mouse and is expressed in a tissue-specific manner with high expression levels in kidney and leg and dorsal muscles. In addition, MEG3 is more abundant in prenatal muscle compared to postnatal muscle, and its expression peaks at gestational day 60. Notably, we observed almost no expression 40 days after birth. The core promoter of MEG3 is located upstream of the transcription initiation site between -447 and -40 bp. In our SNP linkage disequilibrium and association analyses, four of the 10 potential polymorphism sites were found to be associated with corrected back fat thickness and age to reach 100 kg (rs325797437, rs344501106, rs81286029 and rs318656749). In addition, three haplotypes were found to be associated with differences in corrected age to reach 100 kg (AAAT, AAAT/GGGC, GAAT/GGGC). Our results indicate that MEG3 regulates skeletal muscle development and is a candidate gene for improving meat production traits in pigs.

PMID- 30294801 TI - RNA-based markers in biopsy cores with atypical small acinar proliferation: Predictive effect of T2E fusion positivity and MMP-2 upregulation for a subsequent prostate cancer diagnosis. AB - BACKGROUND: Atypical small acinar proliferation (ASAP) is a precursor lesion of prostate cancer (PC), and PC develops from this suspicious focus or an unsampled malignant gland nearby. However, PC-related molecular alterations that could guide the timing of repeat biopsies and help monitor PC risk in ASAP-diagnosed patients have not been investigated. The purpose of this study was to first investigate the expression of seven different PC-related RNAs that included serine 2 (TMPRSS2): erythroblastosis virus E26 oncogene homolog (ERG) gene (TMPRSS2-ERG, T2E) fusion, alpha-methylacyl-CoA racemase (AMACR), kallikrein related peptidase 3 (KLK3), androgen receptor (AR), prostate cancer specific antigen 3 (PCA3), and matrix metalloproteinases (MMP)-2 and 9. METHODS: PC related RNAs were evaluated using a real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR) system in pathologically ASAP-diagnosed prostate biopsy cores from 55 patients presenting with a normal digital rectal examination and a PSA level of 4-10 ng/mL. RESULTS: We detected that positive T2E fusion status (P = 0.013) and the expression of AMACR (P = 0.016), AR (P = 0.016) and MMP-2 (P = 0.013) were independently and significantly associated with PC risk in ASAP patients. There were also several statistically significant correlations between expression levels. Additionally, we demonstrated that T2E fusion positive ASAP patients with higher MMP-2 expression were more likely to be diagnosed with PC at a subsequent biopsy during the follow-up period (P = 0.003). CONCLUSIONS: Although, more clinical validations are needed for the stratification of PC risk in ASAP-diagnosed biopsy cores, our current results indicate that the coexistence of T2E fusion positivity with MMP-2 upregulation may help clinicians adjust their biopsy timetable and/or assessment of PC risk in ASAP-diagnosed patients with a PSA level of 4-10 ng/mL. PMID- 30294802 TI - Collagenous and elastotic marginal plaques of the hand: A potential clue to the diagnosis of alkaptonuria. AB - Collagenous and elastotic marginal plaques of the hand (CEMPH) is a rare, chronic keratoderma characterized by hyperkeratotic linear plaques located along the radial and ulnar aspects of the hands bilaterally. As an isolated finding, CEMPH occurs secondarily to chronic trauma and photodamage. Herein, CEMPH is described as a manifestation of alkaptonuria (AKU). In addition to keloidal collagen, ochronotic fibers and fragmented, thickened elastic fibers were observed. Additionally, mucin deposition-not previously described in this clinical context was also identified. Given their overlapping clinicopathologic features, CEMPH due to AKU should be distinguished from the acquired variant as well as acrokeratoelastoidosis. PMID- 30294804 TI - Coevolution of Lexical Meaning and Pragmatic Use. AB - According to standard linguistic theory, the meaning of an utterance is the product of conventional semantic meaning and general pragmatic rules on language use. We investigate how such a division of labor between semantics and pragmatics could evolve under general processes of selection and learning. We present a game theoretic model of the competition between types of language users, each endowed with certain lexical representations and a particular pragmatic disposition to act on them. Our model traces two evolutionary forces and their interaction: (i) pressure toward communicative efficiency and (ii) transmission perturbations during the acquisition of linguistic knowledge. We illustrate the model based on a case study on scalar implicatures, which suggests that the relationship between underspecified semantics and pragmatic inference is one of coevolution. PMID- 30294803 TI - Assessment of eosinophils in gastrointestinal inflammatory disease of dogs. AB - BACKGROUND: Accurate identification of eosinophils in the gastrointestinal (GI) tract of dogs with eosinophilic GI disease (EGID) by histological evaluation is challenging. The currently used hematoxylin and eosin (H&E) staining method detects intact eosinophils but does not detect degranulated eosinophils, thus potentially underrepresenting the number of infiltrating eosinophils. OBJECTIVE: To develop a more sensitive method for identifying and quantifying both intact and degranulated eosinophils to diagnose EGID more accurately. METHODS: Endoscopically obtained paraffin-embedded intestinal biopsy specimens from dogs with GI signs were examined. The study groups were dogs with eosinophilic enteritis (EE), lymphoplasmacytic and mixed enteritis, and control dogs with GI signs but no histologic changes on tissue sections. Consecutive sections were immunolabeled with monoclonal antibodies (mAbs) against the eosinophil granule protein eosinophil peroxidase (Epx) and stained by H&E, respectively. The number of eosinophils was manually quantified and classified as intact or degranulated. RESULTS: The number of intact eosinophils detected in Epx mAb-labeled duodenal sections was significantly higher compared with that in H&E-stained sections, with a similar relationship noted in the colon and stomach. The Epx mAb allowed the unique assessment of eosinophil degranulation. The number of intact and degranulated eosinophils was significantly higher in duodenal lamina propria of the EE and mixed group compared to the control group. CONCLUSION: Immunohistochemical detection of Epx provides a more precise method to detect GI tract eosinophils compared to H&E staining and could be used as an alternative and reliable diagnostic tool for assessment of biopsy tissues from dogs with EGID. PMID- 30294805 TI - GRAND CHALLENGES IN ASSESSING THE ADVERSE EFFECTS OF CONTAMINANTS OF EMERGING CONCERN ON AQUATIC FOOD WEBS. AB - Much progress has been made in the past decades to understand the sources, transport, fate and biological effects of contaminants of emerging concern (CECs) in aquatic ecosystems. Despite these advancements, significant obstacles remain to comprehensively assess the environmental risks associated with the presence of CECs. Many of these obstacles center around the extrapolation of effects of single chemicals observed in the laboratory or effects observed in individual organisms or species in the field to impacts of multiple stressors on aquatic food webs. In the current review, we identified five challenges that need to be addressed to advance studies of CECs from singular exposure events to multi species aquatic food web interactions: (i) more detailed information on the complexity of mixtures of CECs in the aquatic environment; (ii) understanding sub lethal effects of CECs on a wide range of aquatic organisms; (iii) ascertaining the biological consequences of variable duration CEC exposures within and across generations in aquatic species; (iv) linkage of multiple stressors with CEC exposure in aquatic systems; and (v) documenting the trophic consequences of CEC exposure across aquatic food webs. We review the current literature to demonstrate how these challenges can be addressed to fill knowledge gaps. This article is protected by copyright. All rights reserved. PMID- 30294806 TI - Event Structures Drive Semantic Structural Priming, Not Thematic Roles: Evidence From Idioms and Light Verbs. AB - What are the semantic representations that underlie language production? We use structural priming to distinguish between two competing theories. Thematic roles define semantic structure in terms of atomic units that specify event participants and are ordered with respect to each other through a hierarchy of roles. Event structures instead instantiate semantic structure as embedded sub predicates that impose an order on verbal arguments based on their relative positioning in these embeddings. Across two experiments, we found that priming for datives depended on the degree of overlap in event structures. Specifically, while all dative structures showed priming, due to common syntax, there was a boost for compositional datives priming other compositional datives. Here, the two syntactic forms have distinct event structures. In contrast, there was no boost in priming for dative light verbs, where the two forms map onto a single event representation. On the thematic roles hypothesis, we would have expected a similar degree of priming for the two cases. Thus, our results support event structural approaches to semantic representation and not thematic roles. PMID- 30294807 TI - Risk assessment communication difficulties: An empirical examination of the effects of categorical versus probabilistic risk communication in sexually violent predator decisions. AB - Expert testimony concerning risk and its communication to the trier of fact has important implications for some of the most significant legal decisions. In a simulated sexual violent predator hearing, we examined how mock jurors interpret and use recidivism risk expert testimony communicated either categorically, using verbal labels, or probabilistically, using numeric values. Based upon the STATIC 99R, we compared mock jurors' decision-making and verdicts when we manipulated the style of risk communication across four different risk levels. In terms of verdict decisions, we found that higher risk levels were associated with more commitment decisions, but that this relationship only existed for the categorical risk-communication format. We also replicated previous research demonstrating that participants overestimate recidivism risk in general, especially when higher risk is communicated categorically. Finally, our participants did not differentiate well between the four levels of risk offered, instead apparently employing a more simplistic dichotomy between "low" or "high" risk for both their verdict decisions and their thresholds for commitment. The legal and policy implications of our findings are discussed, as well as suggestions for more effective presentation of expert risk testimony. PMID- 30294808 TI - Eye'll Help You Out! How the Gaze Cue Reduces the Cognitive Load Required for Reference Processing. AB - Referential gaze has been shown to benefit language processing in situated communication in terms of shifting visual attention and leading to shorter reaction times on subsequent tasks. The present study simultaneously assessed both visual attention and, importantly, the immediate cognitive load induced at different stages of sentence processing. We aimed to examine the dynamics of combining visual and linguistic information in creating anticipation for a specific object and the effect this has on language processing. We report evidence from three visual-world eye-tracking experiments, showing that referential gaze leads to a shift in visual attention toward the cued object, which consequently lowers the effort required for processing the linguistic reference. Importantly, perceiving and following the gaze cue did not prove costly in terms of cognitive effort, unless the cued object did not fit the verb selectional preferences. PMID- 30294809 TI - Malnutrition Risk in Hospitalized Children: A Descriptive Study of Malnutrition Related Characteristics and Development of a Pilot Pediatric Risk-Assessment Tool. AB - BACKGROUND: Underrecognition of pediatric malnutrition may affect nutrition interventions and outcomes. Pediatric malnutrition uses more specific etiology based criteria but lacks clarity in implementation guidelines. Study goals were to identify malnutrition and risk among hospitalized patients, characterize malnutrition risk factors, and assess reliability of criteria against outcome measures. MATERIALS AND METHODS: All children 44 weeks postmenstrual age-18 years, admitted for 48 hours during a 16-day period, were included (n = 528). Trained dietitians assessed patients in physical assessments (PA), growth, energy intake, increased nutrient losses (IL), altered absorption of nutrients (AA), hypermetabolism and inflammation, laboratory information, micronutrient deficiency, and functional status. Outcome data assessed were length of stay (LOS), intensive care unit (ICU) LOS, ventilation days, nutrition support, and dietitian intervention. RESULTS: Malnutrition prevalence upon admission was 19.7%. Weight/length or BMI/age z-score (ZS) had no effect on LOS. AA and IL upon admission were independently associated with malnutrition (both, P<.01). Wasting and hypermetabolism were independently associated with longer LOS (P<.01). Other factors associated with longer LOS included IL and inflammation (P < .05). Those with hypermetabolism had significant ZS improvements if followed by a dietitian (P < .05). Wasting via PA was the only factor associated with longer ICU LOS (P < .05). CONCLUSIONS: Identification of risk factors (wasting, hypermetabolism, AA, IL) beyond anthropometrics to define malnutrition and risk is important in prioritizing care in a tertiary pediatric facility. Of great significance is the ability of dietitian-based PA to predict LOS and need for intervention. PMID- 30294810 TI - Word Forms Are Structured for Efficient Use. AB - Zipf famously stated that, if natural language lexicons are structured for efficient communication, the words that are used the most frequently should require the least effort. This observation explains the famous finding that the most frequent words in a language tend to be short. A related prediction is that, even within words of the same length, the most frequent word forms should be the ones that are easiest to produce and understand. Using orthographics as a proxy for phonetics, we test this hypothesis using corpora of 96 languages from Wikipedia. We find that, across a variety of languages and language families and controlling for length, the most frequent forms in a language tend to be more orthographically well-formed and have more orthographic neighbors than less frequent forms. We interpret this result as evidence that lexicons are structured by language usage pressures to facilitate efficient communication.

PMID- 30294812 TI - Programmable Coding Acoustic Topological Insulator. AB - Topological acoustics has recently revolutionized fundamental concepts of acoustic propagation, giving rise to strikingly unique acoustic edge modes immune to backscattering. Despite the rapid progress in this field, simultaneous realization of reconfigurability, intelligentization, and automatic control over acoustic propagation paths is posing a great challenge. This challenge is overcome by proposing the concept of a programmable acoustic topological insulator based on two digital elements "0" or "1," which consist of honeycomb lattice sonic crystals made of cylindrical rods with different diameters. The acoustic propagation paths in the topological insulators can be controlled automatically by programming different coding sequences, which arises from efficient transformation of pseudospin-dependent edge modes on both interfaces of the digital elements. More importantly, a unique unit is experimentally fabricated that has either a "0" or "1" response automatically manipulated by an air cylinder, and design topological insulators with programmable functionality, to realize three digital acoustic devices, such as a single-pole double-throw switch, a single-pole single-throw switch, and a tunable logic gate. The proposed programmable topological insulators may enable future intelligent acoustic devices with exciting reconfigurable and programmable functionalities, which may lead to important advances in various applications, such as integrated acoustics, acoustic security, and information processing. PMID- 30294813 TI - Practical tools and strategies for researchers to increase replicability. AB - A growing body of evidence indicates that the effects reported in many scientific fields may be overestimated or even false. This problem has gained a lot of attention in the field of psychology, where researchers have even started to speak of a 'replication crisis'. Fortunately, a number of measures to rectify this problem have already been proposed and implemented, some inspired by practices in other scientific fields. In this review, I briefly examine this issue in the field of psychology and suggest some practical tools and strategies that researchers can implement to increase replicability and the overall quality of their scientific research. WHAT THIS PAPER ADDS: Researchers can implement many practical tools and strategies to improve replicability of their findings. Strategies include improving statistical inference, pre-registration, multisite collaboration, and sharing data. Different scientific fields could benefit from looking at each other's best practices. PMID- 30294814 TI - Exploring Self-Healing Liquid Na-K Alloy for Dendrite-Free Electrochemical Energy Storage. AB - The development of high-performance dendrite-free liquid-metal anodes at room temperature is of great importance for the advancement of alkali metal batteries. Herein an intriguing self-healing liquid dendrite-free Na-K alloy, fabricated by a facile room-temperature alloying process, aiming for application in potassium ion batteries is reported. Through extensive investigation, its self-healing characteristics are rooted upon a thin solid K2 O layer (KOL) coated on the liquid Na-K alloy. The KOL not only acts as a protective layer to prevent the Na K alloy from making contact with the electrolyte, but also greatly improves the wetting capability and adhesion between the liquid alloy and the carbon matrix (e.g., carbon fiber cloth (CFC)) to form a stable interface. Consequently, the as prepared CFC/KOL@Na-K alloy anode exhibits prominent electrochemical performance with smaller hysteresis (less than 0.3 V beyond 140 cycles at 0.4 mA cm-2 ), better capacity retention, and higher Coulombic efficiency than the CFC/bare Na-K alloy counterpart. When coupled with a potassium Prussian blue (PPB) cathode, the full cell manifests higher capability retention and improved cycling stability. This research deepens the understanding of self-healing Na-K alloys and opens a new way to achieve high-performance dendrite-free alkali metal anodes for application in rechargeable batteries. PMID- 30294815 TI - Effects of capsaicin application on the skin during resting exposure to temperate and warm conditions. AB - We investigated thermoregulatory and cardiovascular responses at rest in a temperate (20 degrees C) and in a warm (30 degrees C) environment (40% RH) without and with the application of capsaicin on the skin. We hypothesized that regardless of environmental temperature, capsaicin application would stimulate heat loss and concomitantly deactivate heat conservation mechanisms, thus resulting in rectal temperature (Tre) and mean blood pressure decline due to excitation of heat-sensitive TRPV1. Ten male subjects were exposed, while seated, for 30 minutes to 20.8 +/- 1.0 degrees C or to 30.6 +/- 1.1 degrees C: without (NCA) and with (CA) application of capsaicin patches on the skin. Thermoregulatory (Tre, proximal-distal skin temperature gradient) and cardiovascular variables (modelflow technique) as well as oxygen uptake were continuously measured. The area under the curve for Tre decline at 20 degrees C was smaller in CA (-2.1 +/- 1.3 a.u.) than in NCA (-0.6 +/- 1.1 a.u., P < 0.01, r = 0.8). Likewise, at 30 degrees C it was smaller in CA (-2.2 +/- 2.1 a.u.) compared to NCA (-0.8 +/- 2.0 a.u., P = 0.02, r = 0.7). Local vasomotor tone and oxygen uptake, were significantly lower by 36.7% +/- 94.2% and 12.3% +/- 12.3%, respectively, with capsaicin compared to NCA (P = 0.05 and P < 0.01, respectively). Additionally, in 30 degrees C CA mean arterial pressure was lower by 10.7% +/- 5.9%, 8.9% +/- 5.9%, and 10.6% +/- 7.0% compared to 30 degrees C NCA, 20 degrees C NCA, and 20 degrees C CA, respectively (P < 0.01, P = 0.02, and P < 0.01, respectively, d = 1.4-1.8). In conclusion, capsaicin application on the skin induced vasodilation and Tre decline. At 30 degrees C CA, thermal responses were accompanied by arterial hypotension most likely due to the interactive effects of both stressors (warm environment and capsaicin) on cutaneous vascular regulation. PMID- 30294816 TI - Weight loss and breast cancer incidence in postmenopausal women. AB - BACKGROUND: Although obesity is an established risk factor for postmenopausal breast cancer, the results of weight loss and breast cancer studies are inconsistent. Therefore, we evaluated associations between weight change and breast cancer risk in postmenopausal women in the Women's Health Initiative Observational Study. METHODS: Postmenopausal women (n = 61,335) who had no prior breast cancer and a normal mammogram had body weight and height measured and body mass index (BMI) calculated at baseline and year 3. Weight change at year 3 was categorized as stable (<5%), loss (>=5%), or gain (>=5%) with further assessment of weight loss intentionality by self-report. Multivariable Cox proportional hazard regression models were used to evaluate relationships between weight change and subsequent breast cancer incidence. RESULTS: During a mean follow-up of 11.4 years with 3061 incident breast cancers, women with weight loss (n = 8175) had a significantly lower risk of breast cancer compared with women whose weight remained stable (n = 41,139) (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.78-0.98; P = .02) with no interaction by BMI. Adjustment for mammography did not alter findings (HR, 0.88; 95% CI, 0.78-0.99) with no significant difference by weight loss intentionality. Weight gain (>=5%) (n = 12,021) was not associated with breast cancer risk (HR, 1.02; 95% CI, 0.93-1.11) but was associated with higher triple-negative breast cancer incidence (HR, 1.54; 95% CI, 1.16-2.05). CONCLUSIONS: Postmenopausal women who lose weight have lower breast cancer risk than those with stable weight. These findings suggest that postmenopausal women who lose weight may reduce their breast cancer risk.

AB - This study aimed to assess the macroscopic appearance, histology and ultrastructure of liver nodular alterations in sharptooth catfish Clarias gariepinus (Burchell, 1822) from a hyper-eutrophic freshwater impoundment. The livers of 25 fish were sampled for microscopy analyses, otoliths were collected for age estimation, and the hepatosomatic index (HSI) was calculated. The light microscopic analysis of the nodular tissue revealed hepatocellular and nuclear pleomorphism, pyknotic nuclei, variation in cytoplasmic appearance and focal areas of cellular alterations (FCAs). An increase in the size and number of melano-macrophage centres, intracellular deposits, steatosis and giant cells was also identified. The ultrastructural alterations identified included cell membrane disruption, irregular shaped nuclei with augmentation of the nucleolus and deformed nuclear envelopes. In addition, we found dilation, proliferation, fragmentation and vesiculation of the cisternae of the rough endoplasmic reticulum (RER). Furthermore, there was an increase in degenerative mitochondria (transparent matrix), swelling of mitochondria and proliferation of both peroxisomes and lysosomes. The histological and ultrastructural alterations identified did not explain the variation in macroscopic colour of the nodules. We did not find a strong positive correlation between age and HSI; however, the oldest fish (18 years) did present the most nodules. PMID- 30294817 TI - Diboron-Assisted Interfacial Defect Control Strategy for Highly Efficient Planar Perovskite Solar Cells. AB - Metal halide perovskite films are endowed with the nature of ions and polycrystallinity. Formamidinium iodide (FAI)-based perovskite films, which include large cations (FA) incorporated into the crystal lattice, are most likely to induce local defects due to the presence of the unreacted FAI species. Here, a diboron-assisted strategy is demonstrated to control the defects induced by the unreacted FAI both inside the grain boundaries and at the surface regions. The diboron compound (C12 H10 B2 O4 ) can selectively react with unreacted FAI, leading to reduced defect densities. Nonradiative recombination between a perovskite film and a hole-extraction layer is mitigated considerably after the introduction of the proposed approach and charge-carrier extraction is improved as well. A champion power conversion efficiency of 21.11% is therefore obtained with a stabilized power output of 20.83% at the maximum power point for planar perovskite solar cells. The optimized device also delivers negligible hysteresis effect under various scanning conditions. This approach paves a new way for mitigating defects and improving device performance.

AB - From a single alpha-silylated carbinol intermediate, easily accessible by carbometallation of cyclopropenes, various scaffolds featuring a quaternary carbon stereocenter could be obtained selectively. The selectivity towards these different products was achieved by either changing the experimental conditions or the nature of the organometallic species involved. PMID- 30294821 TI - The polarity effect of compact ionization chambers used for small field dosimetry. AB - PURPOSE: The recent developments of compact air-filled ionization chambers for use in small photon beams have raised the needs to address the associated polarity effect. The polarity effect of five compact ionization chambers has been quantified at small field sizes. The origins of the polarity effect are studied experimentally and through Monte-Carlo simulations. For this purpose, the one dimensional lateral dose-response functions were determined using positive and negative chamber's polarity. Monte-Carlo simulations were performed to study the underlying mechanism of the polarity effect by quantifying the charge imbalance in the collecting electrode and cable. METHODS: Five novel compact ionization chamber designs have been studied (PTW-Freiburg: Semiflex 3D 31021, PinPoint 3D 31022 and PinPoint 31023; IBA Dosimetry: Razor chamber CC01-G and Razor Nano chamber CC003). Output ratios were measured down to a nominal field side length of 3 mm using both polarities to evaluate the polarity effect at different field sizes. The small field output correction factors were derived using a scintillator detector as reference. To identify the origins of the polarity effect, slit beam measurements were performed to obtain their lateral dose response functions. All measurements were performed using three chamber orientations: axial, radial crossplane, and radial inplane. The chambers were modeled according to the manufacturers' blueprints using the Monte-Carlo package EGSnrc. The charge imbalance due to electrons entering and leaving the inner electrode and cable was studied using an adapted user-code. RESULTS: The output ratios obtained using all five chambers show field size-dependent polarity effects at small field sizes in the axial orientation, whereas no significant field size dependence of the polarity effect has been observed in the radial orientations. The chambers' lateral dose-response functions reveal that the radiation-induced charge imbalance in the inner electrode and cable is the main cause of the observed polarity effect at small field sizes. The effect is weakest for the largest PTW 31021 chamber but intensifies for smaller chambers with decreasing sensitive air volume. Consistent results have been obtained between Monte-Carlo simulations and measurement data. CONCLUSIONS: Awareness needs to be raised so that the polarity effect of novel compact ionization chambers is appropriately accounted for in small field dosimetry. The results in this work are useful to identify the magnitude of the polarity effect correction and to assist in the decisions on choosing the appropriate chambers and setups during measurements. The origins of the observed polarity effect have been elucidated using the chambers' lateral dose-response functions. The adapted Monte-Carlo user code has been used to compute the radiation-induced charge imbalance in the chamber's components. It opens the possibility to study the chamber's design with the aim to minimize its polarity effect. Small field output correction factors computed according to TRS 483 have been reported for these investigated chambers. PMID- 30294822 TI - Factors influencing nursing home placement of patients with dementia: a retrospective, single-centre study in Japan. AB - AIM: This was an exploratory study to examine the factors influencing nursing home placement (NHP) in Japan. METHODS: For this analysis, 633 patients were selected. The data were collected from the clinical records of each patient. A log-rank test was performed. The time from the patient's first visit to the clinic until the nursing home placement was the independent variable. Age (<80 or >=80 years), biological sex (male or female), Clinical Dementia Rating scale (CDR) score (overall index 0.5, 1, 2, or 3), living situation (living alone or with someone), and voxel-based specific regional analysis systems for Alzheimer's disease Z-score (<2 or >=2) were the dependent variables. Survival curves were obtained by using the Kaplan-Meier estimate. After the log-rank test, we conducted a Cox proportional hazards regression analysis. RESULTS: The results of log-rank test indicated that all the variables could significantly influence time to NHP. Cox proportional hazards regression analysis suggested that CDR 3 exhibited the highest hazard ratio and Z-score showed the lowest hazard ratio. There were significant differences in age, sex, CDR 2, CDR 3, and living situation. CONCLUSIONS: The results indicated that the voxel-based specific regional analysis systems for Alzheimer's disease Z-score is unlikely to influence NHP. This may suggest that even if the atrophy in the medial temporal lobe is rather progressed, patients can remain living at their own home with protective factors. Future studies need to investigate the risk and protective factors of time to NHP by combining the variables. PMID- 30294823 TI - Cluster analysis with MOODS-SR illustrates a potential bipolar disorder risk phenotype in young adults with remitted major depressive disorder. AB - OBJECTIVES: Delays in the diagnosis and detection of bipolar disorder can lead to adverse consequences, including improper treatment and increased suicide risk. The Mood Spectrum Self-Report Measure (MOODS-SR) was designed to capture the full spectrum of lifetime mood symptomology with factor scores for depression and mania symptom constellations. The utility of the MOODS-SR as a tool to investigate homogeneous subgroups was examined, with particular focus on a possible bipolar risk subgroup. Moreover, potential patterns of differences in MOODS-SR subtypes were probed using cognitive vulnerabilities, neuropsychological functioning, and ventral striatum connectivity. METHODS: K-mean cluster analysis based on factor scores of MOODS-SR was used to determine homogeneous subgroupings within a healthy and remitted depressed young adult sample (N = 86). Between group comparisons (based on cluster subgroupings) were conducted on measures of cognitive vulnerabilities, neuropsychological functioning, and ventral striatum rs-fMRI connectivity. RESULTS: Three groups of participants were identified: one with minimal symptomology, one with moderate primarily depressive symptomology, and one with more severe manic and depressive symptomology. Differences in impulsivity, neuroticism, conscientiousness, facial perception accuracy, and rs fMRI connectivity exist between moderate and severe groups. CONCLUSIONS: Within a sample of people with and without depression histories, a severe subgroup was identified with potentially increased risk of developing bipolar disorder through use of the MOODS-SR. This small subgroup had higher levels of lifetime depression and mania symptoms. Additionally, differences in traits, affective processing, and connectivity exist between those with a more prototypic unipolar subgrouping and those with potential risk for developing bipolar disorder. PMID- 30294824 TI - Responding to natural disasters: Examining identity and prosociality in the context of a major earthquake. AB - How does a major natural disaster relate to individuals' orientation towards society? We collected repeated cross-sectional surveys before (n = 644) and after the 2010 Chile earthquake (n = 1,389) to examine levels of national identity, prosocial values, helping motivations, and prosocial behaviours in the context of such a calamitous societal event. Our research questions, derived from the literature on helping in times of crisis, considered how natural disasters may implicate identity and prosociality, as well as how identity, prosocial values, and motivations are linked to prosocial action after a disaster. Higher levels of national identity, helping motivations, and disaster-related helping were found after the earthquake, suggesting that in the aftermath of a disaster, people unite under a common national identity and are motivated to take action related to disaster relief. National identity and prosocial values were closely linked to helping after the earthquake, but specific helping motivations rarely predicted prosocial behaviours. Additionally, proximity to the epicentre was related to higher levels of national identity and participation in reconstruction efforts. These findings contribute to our understanding of people's responses to natural disasters and suggest ways of encouraging prosocial behaviour in the aftermath of unexpected tragic events. PMID- 30294825 TI - Cardiac effects of 6 months' dietary nitrate and spironolactone in patients with hypertension and with/at risk of type 2 diabetes, in the factorial design, double blind, randomized controlled VaSera trial. AB - AIMS: The aims of the present study were to explore whether a long-term intervention with dietary nitrate [(NO3 - ), a potential tolerance-free source of beneficial vasoactive nitric oxide] and spironolactone (to oppose aldosterone's potential deleterious cardiovascular effects) improve cardiac structure/function, independently of blood pressure (BP), in patients with/at risk of type 2 diabetes (a population at risk of heart failure). METHODS: A subsample of participants in our double-blind, randomized, factorial-design intervention (VaSera) trial of active beetroot juice as a nitrate source (<=11.2 mmol) or placebo (nitrate depleted) beetroot juice, and either <=50 mg spironolactone or <=16 mg doxazosin (control), had transthoracic cardiac ultrasounds at baseline (n = 105), and at 3 months and 6 months (n = 87) after the start of the intervention. Analysis was by modified intent-to-treat. RESULTS: Nitrate-containing juice (n = 40) decreased left ventricular (LV) end-diastolic volume {-6.3 [95% confidence interval (CI) 11.1, -1.6] ml} and end-systolic volume [-3.2 (95% CI -5.9, -0.5) ml], and increased end-diastolic mass/volume ratio [+0.04 (95% CI 0.00, 0.07)], relative to placebo juice (n = 47). Spironolactone (n = 44) reduced relative wall thickness compared with doxazosin (n = 43) [-0.01 (95% CI -0.02, -0.00)]. Although spironolactone reduced LV mass index relative to baseline [-1.48 (95% CI -2.08, -0.88) g m-2.7 ], there was no difference vs. doxazosin [-0.85 (95% CI 1.76, 0.05) g m-2.7 ]. Spironolactone also decreased the E/A ratio [-0.12 (95% CI -0.19, -0.04)] and increased S' (a tissue-Doppler systolic function index) by 0.52 (95% CI 0.05, 1.0) cm s-1 . BP did not differ between the juices, or between the drugs. CONCLUSIONS: Six months' dietary nitrate decreased LV volumes ~5%, representing new, sustained, BP-independent benefits on cardiac structure, extending mechanisms characterized in preclinical models of heart failure. Spironolactone's effects on cardiac remodelling and systolic-diastolic function, although confirmatory, were independent of BP. PMID- 30294826 TI - Improving the oral health of older people in hospital. AB - OBJECTIVE: To determine whether an oral health therapist daily oral hygiene intervention, compared with the same routine performed by nurses with some dental support, can improve the oral health of older inpatients. METHODS: A prospective study was conducted at two tertiary referral hospitals with three phases: (i) pre intervention (PI) usual oral care; (ii) oral health therapist intervention (OHTI); and (iii) nurse-led intervention (NI). Oral health was assessed with the Oral Health Assessment Tool. RESULTS: Three hundred and fifty nine patients participated across three phases (PI (n = 206); OHTI (n = 77); NI (n = 76)). In the intervention groups, there was a significant decrease in 'unhealthy' oral cleanliness at day 7, OHTI; 86 to 53% (P < 0.001), NI; 80 to 50% (P < 0.001) compared to PI; 78 to 72% (P > 0.14). Movement from 'unhealthy' oral cleanliness at day 1 to 'healthy' at day 7 was significantly higher in the OHTI (35%) and NI (37%) compared to PI (17%) (P < 0.001). CONCLUSION: With support, nurses can improve the oral health of older patients similarly to an oral health therapist.

PMID- 30294828 TI - Effect of methotrexate monotherapy on T-cell subsets in the peripheral circulation in psoriasis. AB - BACKGROUND: Psoriasis is a T-helper (Th)1/Th17-mediated chronic inflammatory disease. There is an increased population of Th cells in skin lesions and peripheral circulation of patients with psoriasis. Systemic methotrexate (MTX) is an effective treatment for moderate to severe psoriasis; however, its effect on different T-cell subsets is not yet clear. AIM: To study the effect of MTX monotherapy on the psoriatic T-cell profile in the peripheral circulation of patients with psoriasis. METHODS: This was a follow-up study involving 50 patients with moderate to severe psoriasis treated with systemic MTX for 12 weeks. Blood samples (5 mL) were collected from participants, from which PBMCs were isolated, and T-cell phenotyping was performed by flow cytometry. RESULTS: Following 12 weeks of MTX treatment, there was an increase in the percentages of Th2/Treg cells, and a relative decrease in the percentages of Th1/Th17 cells, along with a significant reduction in the median Psoriasis Area and Severity Index (PASI). CONCLUSION: MTX helps in the restoration of the immune balance by decreasing the numbers of Th1 and Th17 cells and increasing the numbers of Th2 and Treg cells, thus resulting in a significant reduction in disease severity. MTX converts a proinflammatory T-cell phenotype to a protective anti-inflammatory phenotype, thus significantly suppressing the inflammation in psoriasis. PMID- 30294829 TI - Network-based integration of mRNA and miRNA profiles reveals new target genes involved in pancreatic cancer. AB - Pancreatic cancer is regarded as the most fatal and aggressive malignancy cancer due to its low 5-year survival rate and poor prognosis. The approaches of early diagnosis and treatment are limited, which makes it urgent to identify the complex mechanism of pancreatic oncogenesis. In this study, we used RNA-seq to investigate the transcriptomic (mRNA and miRNA) profiles of pancreatic cancer in paired tumor and normal pancreatic samples from ten patients. More than 1000 differentially expressed genes were identified, nearly half of which were also found to be differentially expressed in the majority of examined patients. Functional enrichment analysis revealed that these genes were significantly enriched in multicellular organismal and metabolic process, secretion, mineral transport, and intercellular communication. In addition, only 24 differentially expressed miRNAs were found, all of which have been reported to be associated with pancreatic cancer. Furthermore, an integrated miRNA-mRNA interaction network was generated using multiple resources. Based on the calculation of disease correlation scores developed here, several genes present in the largest connected subnetwork, such as albumin, ATPase H+ /K+ exchanging alpha polypeptide and carcinoembryonic antigen-related cell adhesion molecule 1, were considered as novel genes that play important roles in the development of pancreatic cancer. Overall, our data provide new insights into further understanding of key molecular mechanisms underlying pancreatic tumorigenesis. PMID- 30294830 TI - The benefits of integrating dental and dental therapy and hygiene students in undergraduate curricula. AB - PURPOSE: The purpose of the current study was to evaluate the impact of integrating the teaching of Bachelor of Dental Surgery (BDS) and Bachelor of Dental Therapy and Hygiene (BScDTH) students in enquiry-based learning (EBL) sessions, using performance on multiple related integrated dental science (IDS) multiple-choice question assessments. METHOD: IDS assessments are sat twice in the first stages of both the BDS and BScDTH programmes. IDS scores from integrated and non-integrated cohorts were collated and compared across test occasions (first or second assessment of the stage) and programmes (BDS and BScDTH). RESULTS: The results revealed that IDS scores were, overall, significantly higher for students in integrated (M = 63.46, SD = 13.06) than non integrated EBL groups (M = 60.75, SD = 13.67; F(1,207) = 4.277, P = 0.040, CONCLUSIONS: Integrating students from different programmes for the teaching of core dental knowledge in team environments improves student performance in subsequent dental science assessments-and more so for BScDTH than BDS students. The fact that both groups benefit from integration should go some way towards reassuring institutions that are considering integration but are cautious of threats to "established" programmes. PMID- 30294831 TI - Detection of MAPK/ERK pathway proteins and KRAS mutations in adenomatoid odontogenic tumors. AB - OBJECTIVE: This study aimed to assess the frequency of KRAS mutation and its association with the presence of the MAPK/ERK signaling pathway proteins in adenomatoid odontogenic tumors. STUDY DESIGN: Paraffin-embedded tissue samples from nine cases of adenomatoid odontogenic tumor were used. Genomic DNA was extracted from each sample; in one case, genetic mutations in 50 cancer associated genes were examined by next-generation sequencing. Hotspot mutations in the RAS family were analyzed by Luminex assay using the remaining eight cases. Subsequently, immunohistochemistry for KRAS, CRAF, BRAF, EGFR, ERK, MEK, and BRAFV600E was performed. RESULTS: A KRAS G12D missense mutation was detected in the DNA sequence of the tumor cells, but it was not detected in the stromal tissue. KRAS G12V and KRAS G12R mutations were detected in two and four cases, respectively. For immunohistochemistry, all the cases were EGFR, KRAS, BRAF, CRAF positive, one case was ERK negative,and one case was MEK and ERK negative, all the other remaining cases were MEK and ERK positive. CONCLUSION: KRAS mutation at codon 12 and the presence of MAPK/ERK pathway proteins were detected suggesting their association with tumorigenesis of adenomatoid odontogenic tumors.

PMID- 30294833 TI - ACVECC-Veterinary Committee on Trauma Registry Report 2013-2017. AB - OBJECTIVE: To report summative data from the American College of Veterinary Emergency and Critical Care Veterinary Committee on Trauma (VetCOT) registry. DESIGN: Multi-institutional veterinary trauma registry data report. SETTING: VetCOT identified veterinary trauma centers (VTCs). ANIMALS: Dogs and cats with evidence of trauma presented to VTCs with data entered in the VetCOT registry September 1, 2013-March 31, 2017. INTERVENTIONS: VetCOT created a standardized data collection methodology for dog and cat trauma. Data were input to a web based data capture system (REDCap) by data entry personnel trained in data software use and operational definitions of data variables. Data on demographics, trauma type (blunt vs penetrating), preadmission care, hospitalization and intensive care requirement, trauma severity assessment at presentation (eg, modified Glasgow coma scale and animal trauma triage score), key laboratory parameters, necessity for surgical intervention, and case outcome were collected. Summary descriptive data for each species are reported. MEASUREMENTS AND MAIN RESULTS: Twenty-nine VTCs in North America, Europe, and Australia contributed information from 17,335 dog and 3,425 cat trauma cases during the 42-month reporting period. A large majority of cases presented directly to the VTC after injury (80.4% dogs and 78.1% cats). Blunt trauma was the most common source for injury in cats (56.7%); penetrating trauma was the most common source for injury in dogs (52.3%). Note that 43.8% of dogs and 36.2% of cats were reported to have surgery performed. The proportion surviving to discharge was 92.0% (dogs) and 82.5% (cats). CONCLUSIONS: The VetCOT registry proved to be a powerful resource for collection of a large dataset on trauma in dogs and cats seen at VTCs. While overall survival to discharge was quite high, further evaluation of data on subsets of injury types, patient assessment parameters, interventions, and associated outcome are warranted. PMID- 30294835 TI - Pathophysiology and Treatment of Gastrointestinal Motility Disorders in the Acutely Ill. AB - Gastrointestinal dysmotility causes delayed gastric emptying, enteral feed intolerance, and functional obstruction of the small and large intestine, the latter functional obstructions being frequently termed ileus and Ogilvie syndrome, respectively. In addition to meticulous supportive care, drug therapy may be appropriate in certain situations. There is, however, considerable variation among individuals regarding what gastric residual volume identifies gastric dysmotility and would encourage use of a promotility drug. While the administration of either metoclopramide or erythromycin is supported by evidence it appears that, dual-drug therapy (erythromycin and metoclopramide) reduces the rate of treatment failure. There is a lack of evidence to guide drug therapy of ileus, but neither erythromycin nor metoclopramide appear to have a role. Several drugs, including ghrelin agonists, highly selective 5-hydroxytryptamine receptor agonists, and opiate antagonists are being studied in clinical trials. Neostigmine, when infused at a relatively slow rate in patients receiving continuous hemodynamic monitoring, may alleviate the need for endoscopic decompression in some patients. PMID- 30294836 TI - Community, Context, and Coping: How Social Connections Influence Coping and Well Being for Military Members and Their Spouses. AB - Military members and their spouses (n = 223 families) were selected from an Active Duty Army installation and assessed with regard to their connections with the military community, their levels of coping with military culture demands, and their reports of individual (depression and life satisfaction) and family well being. Guided by the contextual model of family stress and the social organization theory of action and change, results from a structural equation model indicated that military community connections, for both military members and their civilian spouses, were related to coping with the military culture and its demands, which in turn was related to both individual and family well-being. Unique actor and partner effects also emerged where both active duty military members' and their civilian spouses' perceptions of military community connections influenced the civilian spouses' satisfaction with military life, but only the active duty military members' community connections influenced their military-specific coping. Additionally, the associations between military specific coping and individual and family well-being only had actor effects. When examined within the context of important military culture elements, namely rank and extent of military transitions (deployment and relocation), these core findings linking communities to coping and well-being were unchanged. Implications for theory, future research, and practice are shared. PMID- 30294837 TI - Enzyme-mediated transglycosylation of rutinose (6-O-alpha-l-rhamnosyl-d-glucose) to phenolic compounds by a diglycosidase from Acremonium sp. DSM 24697. AB - The structure of the carbohydrate moiety of a natural phenolic glycoside can have a significant effect on the molecular interactions and physicochemical and pharmacokinetic properties of the entire compound, which may include anti inflammatory and anticancer activities. The enzyme 6-O-alpha-rhamnosyl-beta glucosidase (EC 3.2.1.168) has the capacity to transfer the rutinosyl moiety (6-O alpha-l-rhamnopyranosyl-beta-d-glucopyranose) from 7-O-rutinosylated flavonoids to hydroxylated organic compounds. This transglycosylation reaction was optimized using hydroquinone (HQ) and hesperidin as rutinose acceptor and donor, respectively. Since HQ undergoes oxidation in a neutral to alkaline aqueous environment, the transglycosylation process was carried out at pH values <=6.0. The structure of 4-hydroxyphenyl-beta-rutinoside was confirmed by NMR, that is, a single glycosylated product with a free hydroxyl group was formed. The highest yield of 4-hydroxyphenyl-beta-rutinoside (38%, regarding hesperidin) was achieved in a 2-h process at pH 5.0 and 30 degrees C, with 36 mM OH-acceptor and 5% (v/v) cosolvent. Under the same conditions, the enzyme synthesized glycoconjugates of various phenolic compounds (phloroglucinol, resorcinol, pyrogallol, catechol), with yields between 12% and 28% and an apparent direct linear relationship between the yield and the pKa value of the aglycon. This work is a contribution to the development of convenient and sustainable processes for the glycosylation of small phenolic compounds. PMID- 30294839 TI - A profile of the language and cognitive skills contributing to oral inferential comprehension in young children with developmental language disorder. AB - BACKGROUND: Children with developmental language disorder (DLD) demonstrate poor oral inferential comprehension. Research investigating the skills that underpin oral inferential comprehension in young children with DLD is necessary in order to better understand and improve inferential comprehension in this population. AIMS: To profile the language and cognitive skills that contribute to oral inferential comprehension in young children with DLD. METHODS & PROCEDURES: Seventy-six children aged 5-6 years with a diagnosis of DLD were assessed on a wide range of language and cognitive measures. Oral inferential comprehension of narrative was the primary outcome measure. OUTCOMES & RESULTS: Narrative macrostructure and microstructure, literal comprehension, vocabulary, phonological loop, and theory of mind were significant predictors of inferential comprehension in bivariate analyses. However, multivariate regression analysis indicated that only narrative retell macrostructure and theory of mind contributed a significant amount of unique variance to inferential comprehension. CONCLUSIONS & IMPLICATIONS: This study profiled the skills contributing to oral inferential comprehension in young children with DLD, to support the clinical and theoretical understanding of the ability in this population. The findings have implications for future intervention studies. PMID- 30294838 TI - On the improvement of CBCT image quality for soft tissue-based SRS localization. AB - PURPOSE: We explore the optimal cone-beam CT (CBCT) acquisition parameters to improve CBCT image quality to enhance intracranial stereotactic radiosurgery (SRS) localization and also assess the imaging dose levels associated with each imaging protocol. METHODS: Twenty-six CBCT acquisition protocols were generated on an Edge(r) linear accelerator (Varian Medical Systems, Palo Alto, CA) with different x-ray tube current and potential settings, gantry rotation trajectories, and gantry rotation speeds. To assess image quality, images of the Catphan 504 phantom were analyzed to evaluate the following image quality metrics: uniformity, HU constancy, spatial resolution, low contrast detection, noise level, and contrast-to-noise ratio (CNR). To evaluate the imaging dose for each protocol, the cone-beam dose index (CBDI) was measured. To validate the phantom results, further analysis was performed with an anthropomorphic head phantom as well as image data acquired for a clinical SRS patient. RESULTS: The Catphan data indicates that adjusting acquisition parameters had direct effects on the image noise level, low contrast detection, and CNR, but had minimal effects on uniformity, HU constancy, and spatial resolution. The noise level was reduced from 34.5 +/- 0.3 to 18.5 +/- 0.2 HU with a four-fold reduction in gantry speed, and to 18.7 +/- 0.2 HU with a four-fold increase in tube current. Overall, the noise level was found to be proportional to inverse square root of imaging dose, and imaging dose was proportional to the product of total tube current-time product and the cube of the x-ray potential. Analysis of the anthropomorphic head phantom data and clinical SRS imaging data also indicates that noise is reduced with imaging dose increase. CONCLUSIONS: Our results indicate that optimization of the imaging protocol, and thereby an increase in the imaging dose, is warranted for improved soft-tissue visualization for intracranial SRS.

PMID- 30294841 TI - Can alternative epitope mapping approaches increase the impact of B-cell epitopes in food allergy diagnostics? AB - In vitro allergy diagnostics are currently based on the detection of specific IgE binding on intact allergens or a mixture thereof. This approach has drawbacks as it may yield false-negative and/or false-positive results. Thus, we reviewed the impact of known B-cell epitopes of food allergens to predict transience or persistence, tolerance or allergy and the severity of an allergic reaction and to examine new epitope mapping strategies meant to improve serum-based allergy diagnostics. Recent epitope mapping approaches have been worthwhile in epitope identification and may increase the specificity of allergy diagnostics by using epitopes predominately recognized by allergic patients in some cases. However, these approaches did not lead to discrimination between clinically relevant and irrelevant epitopes so far, since the polyclonal serum IgE-binding epitope spectrum seems to be too individual, independent of the disease status of the patients. New epitope mapping strategies are necessary to overcome these obstacles. The use of patient-derived monoclonal antibodies instead of patient sera for functional characterization of clinically relevant and irrelevant epitope combinations, distinguished by their ability to induce degranulation, might be a promising approach to gain more insight into the allergic reaction and to improve serum-based allergy diagnostics. PMID- 30294842 TI - Normal weight metabolically unhealthy phenotype in youth: do definitions matter? AB - BACKGROUND: Normal weight metabolically unhealthy (NWMU) adults are at increased risk of cardiometabolic disease, however little is known regarding NWMU children. OBJECTIVES: We examined the associations between existing definitions of NWMU in children aged 8-10 years and insulin sensitivity (IS) and secretion 2 years later. METHODS: Data stem from the QUALITY cohort of 630 Caucasian youth, 8-10 years old at baseline, with at least one obese biological parent. Of these, 322 normal weight children were classified as NWMU using 4 definitions. At 10-12 years, IS was measured with the Matsuda-insulin sensitivity index; insulin secretion was measured with the ratio of the area under the curve (AUC) of insulin to the AUC of glucose over a 2-hour OGTT. Multiple linear regression models were used. RESULTS: Because few children met the existing definitions of metabolic syndrome, associations were examined for less stringent definitions (e.g. having 2 vs no risk factors). At baseline, IS was lower in NWMU children compared to children with no risk factors (virtually all definitions). Moreover, after 2 years, IS was 20.5% lower in NWMU children with 1 or more risk factors, and 30.4% lower in those with 2 or more risk factors compared to those with none. Insulin secretion was not predicted by components of the metabolic syndrome. CONCLUSION: Existing definitions of NWMU youth performed relatively similarly in predicting IS as youth entered puberty. Children with one or more components of metabolic syndrome - even when of normal weight - have significantly lower insulin sensitivity over time. This article is protected by copyright.

AB - OBJECTIVE: To assess the effectiveness of controlled-release devices (CRDs) for providing zinc and for estimating faecal output in alpacas and sheep at pasture. METHODS: The study groups of 10 alpacas and 10 sheep at pasture were paired within species and allocated at random to receive by mouth either one CRD containing chromium sesquioxide designed to function for at least 21 days or two CRDs, one containing chromium sesquioxide and the other zinc oxide designed to release over a nominal 60-day period. Faecal concentrations of chromium, zinc and ash, blood and plasma concentrations of zinc and plasma activity of alkaline phosphatase (ALP) were measured over a period of 117 days after treatment. RESULTS: The mean faecal chromium excretion profiles suggested that the CRDs performed in a similar manner in both species, releasing chromium for nearly 30 days in alpacas and for slightly more than 30 days in sheep. Using a common predetermined release rate of chromium from the CRDs, the daily faecal outputs of alpacas and sheep were estimated to be 0.54 kg dry matter and 0.33 kg dry matter, respectively. The CRD containing zinc oxide provided after 1 week an estimated daily release rate of 40 mg zinc with a lifetime of between 60 and 70 days in both species. The additional zinc did not elicit a response in blood zinc concentrations or in plasma ALP activity. CONCLUSION: The CRDs were retained in the gastrointestinal tracts of the alpacas and sheep and both types functioned as expected. The CRD delivering chromium sesquioxide at a known release rate provided an estimate of faecal dry matter output over a period of almost 3 weeks and the CRD formulated to deliver supplementary zinc did so at the nominal release rate over a period of approximately 60 days in both species. These data indicated that the standard sheep CRD is applicable for use in alpacas. PMID- 30294844 TI - The community and ecosystem consequences of intraspecific diversity: a meta analysis. AB - Understanding the relationships between biodiversity and ecosystem functioning has major implications. Biodiversity-ecosystem functioning relationships are generally investigated at the interspecific level, although intraspecific diversity (i.e. within-species diversity) is increasingly perceived as an important ecological facet of biodiversity. Here, we provide a quantitative and integrative synthesis testing, across diverse plant and animal species, whether intraspecific diversity is a major driver of community dynamics and ecosystem functioning. We specifically tested (i) whether the number of genotypes/phenotypes (i.e. intraspecific richness) or the specific identity of genotypes/phenotypes (i.e. intraspecific variation) in populations modulate the structure of communities and the functioning of ecosystems, (ii) whether the ecological effects of intraspecific richness and variation are strong in magnitude, and (iii) whether these effects vary among taxonomic groups and ecological responses. We found a non-linear relationship between intraspecific richness and community and ecosystem dynamics that follows a saturating curve shape, as observed for biodiversity-function relationships measured at the interspecific level. Importantly, intraspecific richness modulated ecological dynamics with a magnitude that was equal to that previously reported for interspecific richness. Our results further confirm, based on a database containing more than 50 species, that intraspecific variation also has substantial effects on ecological dynamics. We demonstrated that the effects of intraspecific variation are twice as high as expected by chance, and that they might have been underestimated previously. Finally, we found that the ecological effects of intraspecific variation are not homogeneous and are actually stronger when intraspecific variation is manipulated in primary producers than in consumer species, and when they are measured at the ecosystem rather than at the community level. Overall, we demonstrated that the two facets of intraspecific diversity (richness and variation) can both strongly affect community and ecosystem dynamics, which reveals the pivotal role of within-species biodiversity for understanding ecological dynamics.

AB - Cerebral palsy (CP) remains the most significant neurological disorder associated with preterm birth. It disrupts quality of life and places huge cost burdens on society. Antenatal magnesium sulphate administration to females before 32 weeks' gestation has proven to be an effective intervention to reduce the rate of CP. In models of hypoxia, hypoxia-ischemia, inflammation, and excitotoxicity in various animal species, magnesium sulphate preconditioning decreased the resulting lesion sizes and inflammatory cytokine levels, prevented cell death, and improved long term cognitive and motor behaviours. In humans, meta-analyses of five randomized controlled trials using magnesium sulphate as a neuroprotectant showed prevention of CP at 2 years. The benefit remained consistent regardless of gestational age, cause of preterm birth, and total dose received. Antenatal magnesium sulphate treatment is now recommended by the World Health Organization and by many obstetric societies. Its cost-effectiveness further justifies its widespread implementation. WHAT THIS PAPER ADDS: Neuroprotective effect of magnesium sulphate to reduce cerebral palsy in infants born preterm when administered to females at risk of imminent preterm birth. Neuroprotection regardless of gestational age, cause of preterm birth, and total dose. Antenatal magnesium sulphate treatment has good cost-effectiveness. PMID- 30294846 TI - Demographic and clinical features of hidradenitis suppurativa in Korea. AB - Hidradenitis suppurativa (HS) is a chronic, relapsing, inflammatory skin disorder. Although several epidemiological studies have been conducted in Western countries, such data regarding Asian populations are scarce. In this study, we sought to investigate the demographic and clinical features of HS in Korea. A total of 438 patients, diagnosed with HS from May 2007 to April 2017, were enrolled and the electronic medical record of each patient was reviewed. Male patients were predominant with a male : female ratio of 2.5:1. Mean age of disease onset was 23.9 years and most patients had no family history. The most frequently affected area was the buttocks, followed by axillae and groin. Acne and diabetes mellitus were the most prevalent associated diseases and no patients with inflammatory bowel diseases were observed. In the univariable analysis, male patients had severe diseases compared with females with an odds ratio (OR) of 1.790. Two or more affected body regions were associated with HS severity with an OR of 1.693. While involvement of the perineum (OR, 4.067) and buttocks (OR, 1.471) tended to be associated with increased severity of the disease, the inguinal area (OR, 0.620) showed a tendency to be inversely associated with the severity. In multivariable analysis, identified risk factors were the involvement of the perineum (OR, 3.819) and buttocks (OR, 2.288). Smoking status and high body mass index seemed to be associated with more severe diseases. Our results will provide clinical characteristics of HS patients in Asia and help to broaden understanding of HS. PMID- 30294847 TI - Loop ileostomy reversal after laparoscopic versus open rectal resection. AB - BACKGROUND: One of the potential advantages of laparoscopic abdominal surgery is in reducing the development of adhesions, making later surgery easier. The purpose of this study is to determine whether using the laparoscopic versus open approach for a rectal resection with a diverting ileostomy affects the speed and safety of subsequent ileostomy reversal. METHODS: This is a retrospective study using patients who underwent ileostomy reversal following a rectal cancer resection with curative intent with a diverting ileostomy at the University Hospital Geelong between January 2006 and June 2017. Demographic information, operative technique and histological staging for the initial resection were recorded. Theatre time and complication rates for the ileostomy reversal were also recorded. RESULTS: A total of 82 patients were included in this study (22 had laparoscopic resections as the primary operation, 50 had open resections and 10 had laparoscopic converted to open resections). The three groups were similar in age, body mass index, American Society of Anesthesiologists score and proportion undergoing chemoradiotherapy. Median (range) theatre time for ileostomy reversal was 118 (50-200) min after a laparoscopic resection, 80 (30 360) min after a laparoscopic converted to open resection and 65 (50-160) min after an open resection (P = 0.009). Complication rates after ileostomy reversal were similar between the three groups (P = 0.97). CONCLUSION: Ileostomy reversal took longer to perform if the primary rectal resection was performed laparoscopically. PMID- 30294848 TI - Use of gastrografin in the management of faecal impaction in patients with severe chronic constipation: a randomized clinical trial. AB - BACKGROUND/AIM: Faecal impaction (FI) is a common cause of lower gastrointestinal tract obstruction. Gastrografin is a water-soluble radiologic contrast agent that may be orally or rectally administered, with proved therapeutic benefits in adhesive small bowel obstruction. Enemas have long been advocated as the best treatment for FI. The purpose of this study was to demonstrate that enteral administration of gastrografin might be more effective than enema in FI treatment inducing intestinal obstruction. METHODS: A double-blinded, controlled and randomized trial was conducted. Participants received 100 mL of gastrografin (gastrografin group) through nasointestinal tube or enemas (enema group) once daily for six consecutive days. Successful faecal disimpaction, FI time to resolution, Bristol Stool Scale, constipation severity, symptom assessment and adverse events were evaluated. RESULTS: A total of 124 patients were eligible, but only 83 were enrolled to this trial (mean age: 44 +/- 15.8 years). Forty-two patients received enemas, and 41 patients received gastrografin, with six dropouts in each group. Successful disimpaction was achieved with enemas (69.44%) and gastrografin (88.57%; P = 0.034), mean duration of impaction was strikingly different between the two groups (67.13 versus 31.67, respectively; P < 0.01). Constipation severity and symptom assessment were significantly reduced in the gastrografin group. CONCLUSION: Gastrografin given through nasointestinal tube was more effective than enema in the treatment of FI inducing colon obstruction. Gastrografin might be taken into consideration as an effective and safe therapeutic option for FI.

AB - BACKGROUND: The aim of our study was to identify the demographics and complications in elderly cervical spine injuries and predictive factors for surgery, complications and mortality. We hypothesized younger healthier patients were more likely to undergo surgical intervention. METHODS: A retrospective review of 225 consecutive patients aged 65 years and over with cervical spine injuries was carried out over a 3-year period. RESULTS: There were 113 males and 112 females with an average of 79.7 years (range 65-98). The most common fracture was C2 peg type (21.8%). Five patients had complete spinal cord injury (2.2%), 25 had incomplete spinal cord injury (11.1%) and 84% were neurologically intact. Fifty-four patients were managed operatively (24%), while 171 patients were managed non-operatively (76%). The operative group had higher rates of pneumonia (odds ratio (OR) 5.3, 95% confidence interval (CI) 2.6-10.7, P < 0.01), cardiac arrhythmia (OR 4.1, 95% CI 1.5-11.2, P < 0.01) and respiratory failure (OR 2.6, 95% CI 1.2-5.5, P < 0.05). There was no difference in mortality between the operative and non-operative group (18.5% and 12.9%, P = 0.3). Patients with complete spinal cord injury had 100% mortality. Significant predictive factors for complications and death were neurological deficits, comorbidities and the presence of other injuries (P < 0.05). Surgery was not predictive for death and the operative group was younger than the non-operative group (P < 0.05). CONCLUSIONS: In the setting of a high complication rate, consideration should be given to palliation in elderly patients with complete spinal cord injury and there must be good rational for surgery. PMID- 30294852 TI - Enhancement of Tumor Homing by Chemotherapy-Loaded Nanoparticles. AB - Targeted delivery of anticancer drugs with nanocarriers can reduce side effects and ameliorate therapeutic efficacy. However, poorly perfused and dysfunctional tumor vessels limit the transport of the payload into solid tumors. The use of tumor-penetrating nanocarriers might enhance tumor uptake and antitumor effects. A peptide containing a tissue-penetrating (TP) consensus motif, capable of recognizing neuropilin-1, is here fused to a neuroblastoma-targeting peptide (pep) previously developed. Neuroblastoma cell lines and cells derived from both xenografts and high-risk neuroblastoma patients show overexpression of neuropilin 1. In vitro studies reveal that TP-pep binds cell lines and cells derived from neuroblastoma patients more efficiently than pep. TP-pep, after coupling to doxorubicin-containing stealth liposomes (TP-pep-SL[doxorubicin]), enhances their uptake by cells and cytotoxic effects in vitro, while increasing tumor-binding capability and homing in vivo. TP-pep-SL[doxorubicin] treatment enhances the Evans Blue dye accumulation in tumors but not in nontumor tissues, pointing to selective increase of vascular permeability in tumor tissues. Compared to pep SL[doxorubicin], TP-pep-SL[doxorubicin] shows an increased antineuroblastoma activity in three neuroblastoma animal models mimicking the growth of neuroblastoma in humans. The enhancement of drug penetration in tumors by TP-pep targeted nanoparticles may represent an innovative strategy for neuroblastoma. PMID- 30294853 TI - Ultrasound-guided catheterization of the femoral artery in a canine model of acute hemorrhagic shock. AB - OBJECTIVE: To describe a technique for gaining ultrasound-guided access to the femoral artery in an experimental model of acute hemorrhagic shock in anesthetized dogs. CASE SERIES SUMMARY: Five healthy, purpose-bred adult male intact Beagles were enrolled in a respiratory mechanics study under general anesthesia. Upon completion of the primary study a hypovolemic state was induced by blood removal to achieve a mean arterial pressure <= 55 mm Hg. Dogs were positioned in dorsal recumbency with the hind limb extended caudally. An ultrasound probe was applied to the medial aspect of the hind limb and positioned in the transverse orientation so that the femoral artery was visualized in its short axis. The artery was identified by lack of compression and presence of visible pulsation. The probe was rotated 90 degrees into the longitudinal orientation such that the artery was visualized in its long axis. Under ultrasound guidance a 19-gauge introducer needle was advanced into the lumen of the femoral artery. Using a modified Seldinger technique the needle was removed and a catheter was placed in the femoral artery. Correct placement of the catheter was verified by observation of the characteristic arterial blood pressure waveform. Upon completion of the study dogs were humanely euthanized. The femoral artery was successfully catheterized in 4/5 dogs and a hematoma was reported in 1/5 dogs. NEW OR UNIQUE INFORMATION PROVIDED: Ultrasound-guided femoral artery catheterization is feasible on anesthetized dogs with concurrent acute hemorrhagic shock. PMID- 30294851 TI - Equine asthma: Integrative biologic relevance of a recently proposed nomenclature. AB - The term "equine asthma" has been proposed as a unifying descriptor of inflammatory airway disease (IAD), recurrent airway obstruction (RAO), and summer pasture-associated obstructive airway disease. Whilst the term will increase comprehensibility for both the lay and scientific communities, its biologic relevance must be compared and contrasted to asthma in human medicine, recognizing the limited availability of peer-reviewed equine-derived data, which are largely restricted to clinical signs, measures of airway obstruction and inflammation and response to therapy. Such limitations constrain meaningful comparisons with human asthma phenotypes. Suggested minimum inclusion criteria supporting the term asthma, as well as similarities and differences between IAD, RAO, and multiple human asthma phenotypes are discussed. Furthermore, differences between phenotype and severity are described, and typical features for equine asthma subcategories are proposed. Based on shared features, we conclude that mild/moderate (IAD) and severe (RAO) equine asthma are biologically appropriate models for both allergic and non-allergic human asthma, with RAO (severe equine asthma) also being an appropriate model for late-onset asthma. With the development of new biologic treatments in humans and the application of more targeted therapeutic approaches in the horse, it would appear appropriate to further investigate the allergic (Th-2) and non-allergic (non-Th-2) phenotypes of equine asthma. Further research is required to more fully determine the potential clinical utility of phenotype classification. PMID- 30294854 TI - Is obstructive sleep apnea associated with ventricular tachycardia? A retrospective study from the National Inpatient Sample and a literature review on the pathogenesis of Obstructive Sleep Apnea. AB - BACKGROUND: Obstructive sleep apnea (OSA) is a known independent risk factor for a multiple cardiovascular morbidities and mortality. The association of OSA and ventricular arrhythmias is less well understood. The aim of this analysis is to study the relationship between OSA and ventricular tachyarrhythmias. HYPOTHESIS: OSA is associated with increased ventricular arrhythmias. METHODS: Data from the national inpatient sample (NIS) 2012 to 2014, were reviewed. Discharges associated with OSA were identified as the target population using the relevant ICD-9-CM codes. The primary outcome was a diagnosis of ventricular tachycardia (VT) in the OSA population. Secondary outcomes include the rate of ventricular fibrillation (VF) and cardiac arrest. Multivariable analyses were performed to examine the association of VT with multiple potential confounding clinical variables. RESULTS: Of 18 013 878 health encounters, 943 978 subjects (5.24%) had a diagnosis of OSA. VT and VF were more prevalent among patients with OSA compared to those without a diagnosis of OSA (2.24% vs 1.16%; P < 0.001 and 0.3% vs 0.2%; P < 0.001, respectively). Odds ratio for cardiac arrest in OSA group was not statistically significant (1, 95% confidence interval 0.97-1.02, P < 0.76). In unadjusted analyses, all examined comorbidities were significantly more common in those with OSA, including diabetes mellitus, hypertension, chronic kidney disease, acute coronary syndrome, and heart failure. CONCLUSION: OSA is associated with increased rates of ventricular tachyarrhythmia. PMID- 30294855 TI - Regulation by biotic stress of tannins biosynthesis in Quercus ilex: crosstalk between defoliation and Phytophthora cinnamomi infection. AB - Sustainability of the Mediterranean forest is threatened by oak decline, a disease of holm oak and other Quercus species that is initiated by infection with the oomycete Phytophthora cinnamomi. Focusing on the role of tannins in the chemical defense of plants, this work investigated whether tannins content in Quercus ilex is regulated by biotic stress. Screening of published genomes allowed the identification of Quercus sequences encoding enzymes for early steps of the biosynthesis of phenolic compounds, like hydrolysable tannins and condensed tannins (CT) among others, plus genes involved in the late steps of CT biosynthesis. Four days after treatment of Q. ilex seedlings by mechanical defoliation, P. cinnamomi infection and both stressors simultaneously, mRNA concentrations for tannins biosynthesis enzymes were measured in leaves. Among the transcript amount for shikimate dehydrogenase (SDH, EC 1.1.1.25), anthocyanidin reductase (EC 1.3.1.77), anthocyanidin synthase (EC 1.14.11.19) and leucoanthocyanidine reductase (EC 1.17.1.3), defoliation induced gene expression for SDH2 isoenzyme. About 4 days after infection of roots by P. cinnamomi, this up-regulation was canceled and SDH enzyme activity decreased. Furthermore, during this late stage of biotrophic interaction the pathogen switched off the correlation engaged by defoliation between the expression of SDH1 and SDH2 encoding genes and chemical defenses corresponding to total tannins, which were down-regulated. Thus, tannins biosynthesis in seedlings of Q. ilex is induced after mechanical defoliation whereas infection by the pathogen interferes with this regulation, potentially increasing the susceptibility of plants to herbivory and aggravating the impact of biotic stress. PMID- 30294856 TI - Current mismatch repair deficiency tumor testing practices and capabilities: A survey of Australian pathology providers. AB - AIM & METHODS: An electronic survey of the Royal College of Pathologists of Australasia accredited pathology services was conducted to assess Lynch syndrome tumor screening practices and to identify barriers and capabilities to screen newly diagnosed colorectal and endometrial tumors in Australia. RESULTS: Australia lacks a national policy for universal mismatch repair-deficient (dMMR) testing of incident colorectal and endometrial tumors cases. Routine Lynch syndrome tumor screening program for colorectal and/or endometrial tumors was applied by 95% (37/39) of laboratories. Tumor dMMR screening methods varied; MMR protein immunohistochemistry (IHC) alone was undertaken by 77% of 39 laboratories, 18% performed both IHC and microsatellite instability testing, 5% did not have the capacity to perform in-house testing. For colorectal tumors, 47% (17/36) reported following a universal approach without age limit, 30% (11/36) tested only "red flag" cases; 6% (3/36) on clinician request only. For endometrial tumors, 37% (12/33) reported clinician request generated testing, 27% (9/33) were screening only "red flag" cases, and 12% (4/33) carried out universal screening without an age criteria. BRAF V600E mutation testing of colorectal tumors demonstrating aberrant MLH1 protein expression by IHC was the most common secondary tumor test, with 53% of laboratories performing the test; 15% of laboratories also applied the BRAF V600E test to endometrial tumors with aberrant MLH1 expression despite no evidence for its utility. Tumor testing for MLH1 promoter methylation was performed by less than 15% laboratories. CONCLUSION: Although use of tumor screening for evidence of dMMR is widely available, protocols for its use in Australia vary widely. This national survey provides a snapshot of the current availability and practice of tumor dMMR screening and identifies the need for a uniform national testing policy. PMID- 30294857 TI - Assessment of plasma lactate and core-peripheral temperature gradient in association with stages of naturally occurring myxomatous mitral valve disease in dogs. AB - OBJECTIVE: To evaluate plasma lactate concentrations and core-peripheral temperature gradients as perfusion parameters in dogs with heart failure caused by myxomatous mitral valve disease (MMVD) and to determine whether the above perfusion parameters are correlated with disease stages. DESIGN: Prospective observational study. SETTING: University teaching hospital. ANIMALS: After excluding 129 dogs because of exclusion criteria, 7 dogs with heart failure classified as stage B2 and 10 dogs classified as stage C according to the American Heart Association (AHA)/American College of Cardiology (ACC) were included in the study. Six dogs without MMVD were evaluated as the control group. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Among the evaluated parameters, the plasma lactate concentrations were increased in stage C (median 3.70 mmol/L [33.3 mg/dL], interquartile range (IQR) 0.72 mmol/L [6.5 mg/dL]) compared with those in the control (median 2.80 mmol/L [25.2 mg/dL], IQR 0.8 mmol/L [7.2 mg/dL]; P = 0.024) and stage B2 groups (median 2.70 mmol/L [24.3 mg/dL], IQR 1.8 mmol/L [16.2 mg/dL]; P = 0.045). Significant differences were not observed in the core-peripheral temperature gradients among the control, stage B2, and stage C dogs. CONCLUSIONS: Dogs with structural heart disease as a result of MMVD may have occult tissue hypoperfusion in stage C that is demonstrated by hyperlactatemia. PMID- 30294858 TI - A NanoFlare-Based Strategy for In Situ Tumor Margin Demarcation and Neoadjuvant Gene/Photothermal Therapy. AB - Accurate tumor margin demarcation in situ remains a paramount challenge. Herein, a NanoFlare (also known as spherical-nucleic-acid technology) based strategy is reported for in situ tumor margin delineation by transforming and amplifying the pathophysiological redox signals of tumor microenvironment. The NanoFlare designed (named AuNS-ASON) is based on gold nanostar (AuNS) coated with a dense shell of disulfide bridge-inserted and cyanine dyes-labeled antisense oligonucleotides (ASON) targeting survivin mRNA. The unique anisotropic ASON spike nanostructure endows the AuNS-ASON with universal cellular internalization of tumor cells, while the disulfide bridge inserted confers response specificity toward redox activation. In vitro experiments demonstrate that the AuNS-ASON can discriminate tumor cells rapidly with activated fluorescence signals (>100-fold) in 2 h, and further achieve synergistic gene/photothermal tumor cells ablation upon near-infrared laser irradiation. Remarkably, in situ tumor margin delineation with high accuracy and outstanding spatial resolution (<100 um) in mice bearing different tumors is obtained based on the AuNS-ASON, providing intraoperative guidance for tumor resection. Moreover, the AuNS-ASON can enable efficient neoadjuvant gene/photothermal therapy before surgery to reduce tumor extent and increase resectability. The concept of NanoFlare-based microenvironment signal transformation and amplification could be used as a general strategy to guide the design of activatable nanoprobes for cancer theranostics. PMID- 30294859 TI - Expression of neutrophil surface markers in icteric neonates before and after phototherapy. AB - BACKGROUND: Jaundice due to indirect hyperbilirubinemia affects more than 60% of neonates and phototherapy is the treatment for severe types. There are no previous studies evaluating the effect of phototherapy on the function of neonates neutrophils. The aim of this study was to assess and compare the function of neutrophils by measuring the expression of neutrophils main surface markers in icteric neonates before and after phototherapy. METHODS: Neonates at a gestational age >=35 weeks and birth weight >=2,000 g who met the American Academy of Pediatrics criteria for phototherapy were included. Flow cytometry evaluation of the mean fluorescence intensities of CD10, CD11b, CD11c, CD15, CD16, CD18, CD62L, CD64, and CD66acde was performed before and 24 h after the initiation of phototherapy. RESULTS: Twenty-five neonates at a mean age of 53 h of life were included in the study with a mean bilirubin level of 13.60 +/- 2.85 mg/dL. There was no statistical difference in the expression of CD11b, CD15, CD18, CD62L, and CD64 or in the percentage of neutrophils before and after 24 h of phototherapy. There was an increase in the expression of CD10 and CD16 and a decrease in the expression of CD11c and CD66acde after 24 h of phototherapy. CONCLUSIONS: Newborns submitted to phototherapy had an increase in the expression of CD10 and CD16 and a decreased in the expression of CD11c and CD66acde after 24 h of treatment, which may be related to an anti-inflammatory effect of phototherapy. PMID- 30294860 TI - Ambient Air Condition for Room-Temperature Deposition of MAPbI3 Films in Highly Efficient Solar Cells. AB - The power conversion efficiency of perovskite solar cells has been boosted rapidly, it has so far exceeded that of commercial polycrystalline silicon solar cells. This has prompted great interest in large-scale production and deployment of perovskite solar cells. However, state-of-the-art perovskite solar cells are fabricated inside gloveboxes and further annealing at high temperatures (typically at >100 degrees C for 30 min) is needed. These two required conditions are not compatible with, either in the respect to high-throughput or thermal budget, a feasible industrial production process. By eliminating the two requirements, the deposition of perovskite films both at room temperature and under ambient air condition will make the scalable roll-to-roll fabrication scheme feasible. Here, the anti-solvent (chloroform) washing is introduced to the previously developed hydrochloride-assisted method and demonstrate that the room temperature method can be carried out under ambient air condition for MAPbI3 film deposition. Through this new procedure, a power conversion efficiency as high as 17.72% is achieved for MAPbI3 planar devices fabricated under a relative humidity of 30% at room temperature. Further, it is revealed that the room-temperature process MAPbI3 films show a near monoexponential decay pathway with a long photoluminescence lifetime of >400 ns. PMID- 30294861 TI - Recombinant mouse calcitonin gene-related peptide secreted by Lactococcus lactis inhibits lipopolysaccharide-induced inflammatory response in macrophages. AB - We describe the development of a genetically modified strain of lactic acid bacteria (gmLAB) capable of producing a recombinant mouse calcitonin gene-related peptide (rCGRP). This strain (NZ-CGRP) was generated by introducing a CGRP secretion plasmid into Lactococcus lactis NZ9000. Western blotting confirmed the secretion of rCGRP in the presence of the inducer nisin. Highly purified rCGRP was obtained from the culture supernatants of NZ-CGRP. We demonstrated that prophylactic exposure of a culture of mouse peritoneal macrophages to rCGRP inhibited lipopolysaccharide (LPS) induction of tumor necrosis factor-alpha (TNF alpha). The rCGRP-secreting gmLAB strain holds promise for development as a new anti-inflammatory prophylactic.

PMID- 30294862 TI - Magnetic Shape Memory Turns to Nano: Microstructure Controlled Actuation of Free Standing Nanodisks. AB - Magnetic shape memory materials hold a great promise for next-generation actuation devices and systems for energy conversion, thanks to the intimate coupling between structure and magnetism in their martensitic phase. Here novel magnetic shape memory free-standing nanodisks are proposed, proving that the lack of the substrate constrains enables the exploitation of new microstructure controlled actuation mechanisms by the combined application of different stimuli i.e., temperature and magnetic field. The results show that a reversible areal strain (up to 5.5%) can be achieved and tuned in intensity and sign (i.e., areal contraction or expansion) by the application of a magnetic field. The mechanisms at the basis of the actuation are investigated by experiments performed at different length scales and directly visualized by several electron microscopy techniques, including electron holography, showing that thermo/magnetomechanical properties can be optimized by engineering the martensitic microstructure through epitaxial growth and lateral confinement. These findings represent a step forward toward the development of a new class of temperature-field controlled nanoactuators and smart nanomaterials. PMID- 30294864 TI - Silk Fibroin Microparticles with Hollow Mesoporous Silica Nanocarriers Encapsulation for Abdominal Wall Repair. AB - Therapeutic vascularization appears to be an effective way of repairing abdominal wall defects. Attempts to implement this treatment tend to focus on the generation of featured drug carriers with the ability effectively to encapsulate the angiogenesis-stimulating agents and control their release to maintain an appropriate concentration at the injured area. Here, a new type of composite microparticle (CM) composed of silk fibroin (SF) and hollow mesoporous silica nanocarriers (HMSNs) is presented for therapeutic agent delivery. The CMs are generated by drying microfluidic emulsion templates of HMSN-dispersed SF solution. The resultant CMs have a distinctive micro-nanostructure, in which two barriers control the drug release. The encapsulated HMSNs increase the drug carrying capacity of the CMs, and also form the first barrier via physical absorption. The microfluidic SF microparticles not only provide a shell with excellent monodispersity and biocompatibility but also form the second barrier via efficient encapsulation. Because of these superior properties of the CMs, the loaded drugs can be delivered with a satisfactory activity at the required rate, making them ideal for implementing therapeutic vascularization and repairing abdominal wall defects. PMID- 30294865 TI - Sexual activity and life satisfaction in older adults. AB - AIM: Based on the concept of successful ageing and research reports on the benefits of maintaining sexual activity in mid- to late life, the purpose of the current study was to examine the relationship between global life satisfaction and sexual satisfaction in adults older than 60 years. The study also analyzed the relationship between various forms of sexual activity (genital and non genital) and both types of satisfaction. METHODS: Thirty-three men and 50 women (N =83) were interviewed by using two structuralized questionnaires. Global life satisfaction was measured with Diener's Satisfaction with Life Scale, whereas sexual satisfaction and preferences regarding various intimate behaviours (i.e. kissing, cuddling, touching partner's intimate body parts, penetration, and masturbation) were assessed with a questionnaire devised for the purpose of the study. Statistical analyses were conducted to verify the relationships among the variables, group differences, and the statistical significance of sexual satisfaction as a predictor of global life satisfaction. RESULTS: Most of the interviewed subjects have had engaged in sexual activity in the last 1-6 months before the study (60%). Participants declared that they mostly engage in subtle forms of sexual activity rather than having intercourse. The level of sexual activity of older adults was positively associated with both sexual and global life satisfaction, but different forms of intimacy had a different impact on satisfaction. Gender was not correlated with the level of sexual and global life satisfaction. CONCLUSIONS: Sexual satisfaction was a good predictor of global life satisfaction in older adults in our study. The participants appeared less concerned with the frequency of their intimate activities and more with engaging in the type of behaviour they were able to enjoy, which shows that they were adapting to the ageing process and potential health issues.

AB - The pulmonary valve normally consists of 3 leaflets supported in a semilunar fashion within the sinuses of the pulmonary trunk. Pulmonary leaflet malformations, such as congenital single pulmonary cusp absence, bicuspid pulmonary valve, and quadricuspid pulmonary valve anomalies, as well as pulmonary valve commissural fusion, are seldom identified preoperatively on echocardiography. In this study, we report on 5 children with different types of pulmonary valve malformations diagnosed by transthoracic echocardiography. PMID- 30294867 TI - Photothermal Convection Lithography for Rapid and Direct Assembly of Colloidal Plasmonic Nanoparticles on Generic Substrates. AB - Controlled assembly of colloidal nanoparticles onto solid substrates generally needs to overcome their thermal diffusion in water. For this purpose, several techniques that are based on chemical bonding, capillary interactions with substrate patterning, optical force, and optofluidic heating of light-absorbing substrates are proposed. However, the direct assembly of colloidal nanoparticles on generic substrates without chemical linkers and substrate patterning still remains challenging. Here, photothermal convection lithography is proposed, which allows the rapid placement of colloidal nanoparticles onto the surface of diverse solid substrates. It is based on local photothermal heating of colloidal nanoparticles by resonant light focusing without substrate heating, which induces convective flow. The convective flow, then, forces the colloidal nanoparticles to assemble at the illumination point of light. The size of the assembly is increased by either increasing the light intensity or illumination time. It is shown that three types of colloidal gold nanoparticles with different shapes (rod, star, and sphere) can be uniformly assembled by the proposed method. Each assembly with a diameter of tens of micrometers can be completed within a minute and its patterned arrays can also be achieved rapidly.

AB - BACKGROUND: Traditional skin preparation for shoulder surgery is not specific for Propionibacterium acnes. Topical benzoyl peroxide for 48 h preoperatively has been shown to reduce the bacterial load of P. acnes on the skin. Our aim was to investigate whether skin preparation with a single application of benzoyl peroxide combined with 2% chlorhexidine/alcohol immediately prior to surgery was superior to 2% chlorhexidine/alcohol alone at inhibiting P. acnes. METHODS: We conducted a single-blinded interventional study. Each shoulder of the participant was assigned a different preparation through a randomization process. Two sites were assessed per shoulder. The intervention was the application of benzoyl peroxide followed by chlorhexidine/alcohol to the shoulder. The control was two applications of 2% chlorhexidine/alcohol. Superficial skin swabs for semi quantitative culture were taken pre- and post-skin preparation. RESULTS: A total of 22 male participants were randomized. All participants were colonized with P. acnes on baseline swabs. We found complete inhibition of P. acnes at 14 days at 80% of sites prepared with benzoyl peroxide + chlorhexidine/alcohol compared with 86% inhibition at shoulder sites prepared with chlorhexidine alone. CONCLUSION: There was no reduction in the growth of P. acnes over 14 days with chlorhexidine/alcohol and benzoyl peroxide compared with chlorhexidine alone. On the basis of these results, the addition of benzoyl peroxide at the time of surgery does not appear to increase the efficacy of the surgical preparation for inhibiting P. acnes growth. PMID- 30294869 TI - Autistic traits in neurotypical individuals are associated with increased landmark use during navigation. AB - People adopt two distinct learning strategies during navigation. "Spatial learners" navigate by building a cognitive map using environmental landmarks, and display more grey matter in the hippocampus. Conversely, "response learners" memorize a series of rigid turns to navigate and display more grey matter in the caudate nucleus of the striatum. Evidence has linked these two structures with autism spectrum disorder (ASD) and autistic traits in non-clinical populations. Both people with ASD and neurotypical people with higher levels of autistic traits have been shown to display more grey matter in the hippocampus and less functional activity in the caudate nucleus. We therefore tested 56 healthy participants who completed the Autism Quotient (AQ) Scale and the 4-on-8 Virtual Maze (4/8 VM), which determines the reliance on landmarks during navigation. We found that people who relied on landmarks during navigation also displayed significantly higher scores on the AQ Scale. Because spatial strategies are associated with increased attention to environmental landmark use and are supported by the hippocampus, our results provide a potential behavioral mechanism linking higher autistic traits (e.g., increased attention to detail and increased sensory processes) to increased hippocampal grey matter. PMID- 30294870 TI - Microbial translocation and T cell activation are modified by direct-acting antiviral therapy in HCV-infected patients. AB - BACKGROUND: Microbial translocation from the gut lumen has been involved in the pathogenesis of liver damage in hepatitis C virus (HCV) infection. AIM: To investigate the impact of direct-acting antiviral treatment on microbial translocation and T-cell activation, in patients with hepatitis C-related liver disease. METHODS: We enrolled two groups of HCV-infected patients undergoing direct-acting antiviral treatment: patients with fibrosis >=F3 according to Metavir (Group >=F3); patients with hepatitis C recurrence after liver transplantation and Metavir >=F2 (Group Liver Transplantation + >=F2). All patients were treated with direct-acting antivirals based on ongoing guidelines. Surrogate biomarkers of microbial translocation (plasma concentrations of soluble CD14, lipopolysaccharide-binding protein and intestinal fatty acid-binding protein) were evaluated at baseline, at first month, at the end of treatment and 3 months later. T-cell activation was measured by expression of CD38+ HLA-DR at the same time points, only in Group >=F3. RESULTS: There were 32 patients in Group >=F3 and 13 in Group LT + >=F2. At baseline, levels of soluble-CD14 and lipopolysaccharide-binding protein were significantly higher in both groups vs healthy controls. Baseline soluble-CD14 correlated with glutamic-oxalacetic transaminase (r = 0.384, P = 0.009) and glutamic-pyruvic transaminase (r = 0.293, P = 0.05). A significant decrease in plasma levels of surrogate microbial translocation biomarkers was observed during and after treatment in the two groups although values were not normalised. In Group >=F3, CD38+ HLADR+ T-cell expression was significantly decreased by direct-acting antiviral treatment. Relapsers (9%) showed higher soluble-CD14 levels at baseline. CONCLUSION: Surrogate microbial translocation markers and T cell activation are increased in HCV-infected patients with liver fibrosis and decrease during direct-acting antiviral treatment. PMID- 30294871 TI - BRAF mutation in papillary thyroid cancer-Prevalence and clinical correlation in a South-East Asian cohort. AB - OBJECTIVE: BRAF mutation is the commonest mutation seen in papillary thyroid cancer (PTC), but its prevalence and clinical significance vary across countries. We aim to evaluate the prevalence and clinico-pathological correlation of BRAF mutation in PTC patients at our centre. STUDY DESIGN: Retrospective cohort study of 75 consecutive archival thyroid specimens, whereby BRAF mutation was detected using a polymerase chain reaction (PCR) technique and correlated with clinical and pathological features and outcomes. SETTING: Tertiary university hospital in Singapore. PARTICIPANTS: A total of 75 consecutive histologically proven archival thyroid specimens from patients who underwent thyroidectomy for PTC were accrued for this study. MAIN OUTCOME MEASURES: Main outcome is to determine the prevalence of the BRAF mutation in our South-East Asian population. Secondary aim is to correlate the mutational status with adverse pathological features like histological variants, multi-focality, lymphovascular invasion and extra thyroidal extension, clinical features like demographics, TNM stage, recurrence and survival, as well as treatment details like type of surgery performed and radioiodine doses. RESULTS: BRAF mutation was detected in 56% (42/75) of PTC. All but one BRAF-mutated PTC had the BRAFV600E mutation. BRAF-mutated tumours were associated with an advanced T-stage (P = 0.049) and were more likely to have a central neck dissection (P = 0.036). There was no significant correlation between BRAF mutation status and clinical outcomes. CONCLUSION: The prevalence of BRAF mutation is 56%. BRAF mutation-positive tumours were associated with locally advanced disease, but not poorer survival. PMID- 30294872 TI - The experience of maternity care for migrant women living with female genital mutilation: A qualitative synthesis. AB - BACKGROUND: Increasing numbers of childbearing women with a history of female genital mutilation (FGM) are accessing maternity services in high-income countries across the world. For many of these women, their first contact with the health services in their host country is when they are pregnant. While the clinical consequences of certain categories of FGM are well documented, how high risk maternity services - designed to mitigate the obstetric consequences of FGM impact upon women's experience of childbearing is less clear. METHODS: Using a meta-synthesis approach, this paper synthesizes 12 qualitative research papers, conducted in 5 high-income countries, to explore how migrant women with a history of FGM experience maternity care in their host countries. RESULTS: One over arching theme and four discrete subthemes of migrant women's experience of the maternity services in their host country were identified: feelings of alienation; fatalism and divine providence, positive and negative feelings about maternity care, different understandings of the birthing process, and feelings about FGM. CONCLUSIONS: The findings illustrate that migrant women with a history of FGM frequently encounter negative attitudes when accessing the maternity services in their host countries. Women's experiences suggest a concerning absence of sensitive and empathetic care; a more woman-centered approach is recommended. PMID- 30294873 TI - Appropriateness of pediatric outpatient transthoracic echocardiogram orders following cessation of an active educational intervention. AB - OBJECTIVE: The educational intervention (EI) through the Pediatric Appropriate Use of Echocardiography (PAUSE) multicenter study resulted in improved appropriateness of transthoracic echocardiogram (TTE) orders at our center. The current study evaluated if this pattern persisted after cessation of EI and the potential physician characteristics influencing appropriateness. DESIGN: Outpatients (<=18 years old) seen for initial evaluation during the EI (July to October, 2015) and 6-month post-EI (May to August, 2016) phases were included. Comparison was made between TTE rates and appropriateness ratings during EI and post-EI phase. Association between TTE rate and appropriateness with physician characteristics (age, experience, patient volume, and area of practice) was determined using odds ratio. RESULTS: The study included 7781 patients (EI: N = 4016; post-EI: N = 3765) seen by 31 physicians. Comparison of appropriateness ratings in a randomized sample (EI: N = 1270; post-EI: N = 1325 patients) showed no significant differences between the two phases (appropriate: 75.2% vs 74.9%, P = .960; rarely appropriate 4.1% vs 6.5%, P = .065). Though there was significant variability among physicians for TTE order appropriateness (P = .044) and ordering rate (P <.001), none of their characteristics were associated with appropriateness and only a higher patient volume was associated with decreased odds of TTE ordering (OR =0.7). CONCLUSION: The PAUSE study EI resulted in maintaining appropriate utilization of TTEs at our center for 6 months following its cessation. Though not statistically significant, there was a trend toward increase in the proportion of studies for indications designated rarely appropriate (R). There was significant physician variability in TTE ordering and appropriateness during both phases. Development of EI to reduce physician variability and integration of EI with provider workflow may help sustain appropriate TTE utilization. PMID- 30294874 TI - Organisational learning in hospitals: A concept analysis. AB - AIM: To provide a clear definition and description of organisational learning in hospitals. BACKGROUND: Organisational learning is a promising strategy nurse managers, and leaders can use to improve organisational performance. A clear definition and description of organisational learning is necessary to advance theory, research and practice in this field. METHODS: Walker & Avant's method was used to conduct a concept analysis of organisational learning in hospitals. Data sources included 147 empirical studies, 16 review articles, three dictionary entries and three book chapters. RESULTS: Organisational learning occurs when experiences are translated into positive changes in the organisation's collective knowledge, cognition and actions. Organisational context plays a key role in the learning process. Other manifestations of the concept are identified. CONCLUSIONS: This concept analysis provides a clear definition of organisational learning and a description of its defining attributes, antecedents, empirical referents and consequences. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers and leaders can improve patient and organisational outcomes by creating an environment conducive to translating experiences into organisational learning. Further research is needed to continue advancing the science of organisational learning in hospitals. PMID- 30294875 TI - Effect of electrode separation on high-resolution impedance manometry catheters for ex vivo animal experiments. AB - BACKGROUND: High-resolution impedance manometry (HRIM) catheters are used for esophageal reflux and bolus transit studies. Usually, these catheters have electrodes spaced at 20 mm intervals that are used for measuring electrical impedance between the consecutive electrodes and pressure sensors with 10 mm separation. Electrical impedance is a distributed measurement between the electrodes, unlike the point measurement of pressure sensors. Thus, the electrode separations affect the overall spatiotemporal resolution of the measurement. METHODS: A 3D model of the gastrointestinal tract, in which bolus shape and size can be modified, was used to simulate the admittance signal response of an intraluminal impedance catheter with 10 and 20 mm electrode separation to study the distributed sensitivity in the lumen to gain insight on the impedance measurement. In addition, experiments on sections of rabbit proximal colon were conducted with two catheters with electrode separations of 10 and 20 mm to compare the experimental data with the simulated data. KEY RESULTS: Reducing electrode spacing from 20 to 10 mm increased sensitivity to diameter change by a factor of ten. Admittance and diameter correlated strongly during a myogenic contraction with a Pearson's Correlation Coefficient of 0.86 for the custom catheter, in comparison with 0.56 for the commercial HRIM catheter. CONCLUSIONS: Ten millimeter electrode separation has a better spatiotemporal resolution, and unlike 20 mm electrode separation is able to identify myogenic contractions. Based on the numerical and experimental data, closer electrode separation should be considered for improved spatial resolution. PMID- 30294876 TI - Impact of cell cycle dynamics on pathology recognition: Raman imaging study. AB - Confocal Raman imaging combined with fluorescence-activated cell sorting was used for in vitro studies of cell cultures to look at biochemical differences between the cells in different cell phases. To answer the question what is the impact of the cell cycle phase on discrimination of pathological cells, the combination of several factors was checked: a confluency of cell culture, the cell cycle dynamics and development of pathology. Confluency of 70% and 100% results in significant phenotypic cell changes that can be also diverse for different batches. In 100% confluency cultures, cells from various phases become phenotypically very similar and their recognition based on Raman spectra is not possible. For lower confluency, spectroscopic differences can be found between cell cycle phases (G0 /G1 , S and G2 /M) for control cells and cells incubated with tumor necrosis factor alpha (TNF-alpha), but when the mycotoxin cytochalasin B is used the Raman signatures of cell phases are not separable. Generally, this work shows that heterogeneity between control and inflamed cells can be bigger than heterogeneity between cell cycle phases, but it is related to several factors, and not always can be treated as a rule. PMID- 30294877 TI - Editors' Introduction and Review: Sociolinguistic Variation and Cognitive Science. AB - Sociolinguists study the interaction between language and society. Variationist sociolinguistics - the subfield of sociolinguistics which is the focus of this issue - uses empirical and quantitative methods to study the production and perception of linguistic variation. Linguistic variation refers to how speakers choose between linguistic forms that say the same thing in different ways, with the variants differing in their social meaning. For example, how frequently someone says fishin' or fishing depends on a number of factors, such as the speaker's regional and social background and the formality of the speech event. Likewise, if listeners are asked to use a rating scale make judgements about speakers who say fishin' or fishing, their ratings depend on what other social characteristics are attributed to the speaker. This issue aims to reflect the growing number of interactions that bring variationist sociolinguistics into contact of different branches of cognitive science. After presenting current trends in sociolinguistics, we identify five areas of contact between the two fields: cognitive sociolinguistics, sociolinguistic cognition, acquisition of variation, computational modeling, and a comparative approach of variation in animal communication. We then explain the benefits of interdisciplinary work: fostering the study of variability and cultural diversity in cognition; bringing together data and modeling; understanding the cognitive mechanisms through which sociolinguistic variation is processed; examining indexical meaning; exploring links between different levels of grammar; and improving methods of data collection and analysis. Finally we explain how the articles in this issue contribute to each of these benefits. We conclude by suggesting that sociolinguistics holds a strategic position for facing the challenge of building theories of language through integrating its linguistic, cognitive, and social aspects at the collective and individual levels. PMID- 30294878 TI - Reciprocal relationships between self-efficacy, outcome satisfaction, and attendance at an exercise programme. AB - OBJECTIVES: The objectives of this study were to (i) investigate directional influences of self-efficacy, outcome satisfaction, and attendance during an exercise programme and (ii) examine the predictive capabilities of self-efficacy and outcome satisfaction on participant dropout. METHODS: Adults aged 35-65 years were recruited to a 12-month exercise programme. Self-efficacy was collected at baseline, three, six, nine, and 12 months, and outcome satisfaction at the same time-points except baseline. Cross-lagged panel analyses and logistic regression analyses were conducted to examine the primary and secondary objectives, respectively. RESULTS: Coping and scheduling self-efficacy had stronger reciprocal relationships with outcome satisfaction than task self-efficacy, although the strength of these relationships varied across time. Initially, task self-efficacy predicted programme attendance. Midway through the programme, outcome satisfaction predicted attendance, and by the end of the programme, coping self-efficacy was the strongest predictor of attendance. Self-efficacy and outcome satisfaction did not predict programme dropout. CONCLUSIONS: The results support the reciprocal relationship between outcome satisfaction and scheduling and coping self-efficacy and highlight the importance of sequentially targeting different beliefs and skills to facilitate successful initiation and maintenance of exercise behaviour. Statement of contribution What is already known on this subject? Self-efficacy and outcome satisfaction are related to exercise behaviour. The relationship between self-efficacy and outcome satisfaction are typically considered unidirectional. The longitudinal relationships among self efficacy, outcome satisfaction, and physical activity participation are unclear. What does this study add? Outcome satisfaction had reciprocal relationships with both coping and scheduling self-efficacy for exercise. The importance of self efficacy and outcome satisfaction to exercise attendance changes over time. Task self-efficacy was the strongest predictor of initial programme attendance. Midway through the programme, outcome satisfaction and task self-efficacy were the strongest predictors of attendance, and by the end of the programme, coping self efficacy was the strongest predictor. PMID- 30294879 TI - Cyano Modification on Uridine Decreases Base-Pairing Stability and Specificity through Neighboring Disruption in RNA Duplex. AB - 5-Cyanomethyluridine (cnm5 U) and 5-cyanouridine (cn5 U), the two uridine analogues, were synthesized and incorporated into RNA oligonucleotides. Base pairing stability and specificity studies in RNA duplexes indicated that cnm5 U slightly decreased the stability of the duplex but retained the base-pairing preference. In contrast, cn5 U dramatically decreased both base-pairing stability and specificity between U:A and other noncanonical U:G, U:U, and U:C pairs. In addition, the cn5 U:G pair was found to be stronger than the cn5 U:A pair and the other mismatched pairs in the context of a RNA duplex; this implied that cn5 U might slightly prefer to recognize G over A. Our mechanistic studies by molecular simulations showed that the cn5 U modification did not directly affect the base pairing of the parent nucleotide; instead, it weakened the neighboring base pair in the 5' side of the modification in the RNA duplexes. Consistent with the simulation data, replacing the Watson-Crick A:U pair to a mismatched C:U pair in the 5'-neighboring site did not affect the overall stability of the duplex. Our work reveals the significance of the electron-withdrawing cyano group in natural tRNA systems and provides two novel building blocks for constructing RNA-based therapeutics. PMID- 30294881 TI - Distribution of Pacini-Like Lamellar Corpuscles in the Vascular Sheath of the Femoral Artery. AB - Pacinian corpuscles are vibration-sensing mechanoreceptors that are densely distributed in the dermis of the human hand. Although they are also known to occur in various other regions/structures throughout the human body, including the adventitia of large vessels, their precise distribution and function in arteries remain unclear. In the present study, we identified Pacini-like lamellar corpuscles (LCs) adjacent to the femoral artery, and investigated their distribution with respect to that structure via a histological analysis. We identified nine LCs that were localized in the connective tissue surrounding the femoral artery and vein. We showed that although their distribution was heterogeneous, they were predominantly concentrated on the dorsal side of the femoral artery. Immunohistochemical analyses revealed that the identified femoral artery LCs exhibited features characteristic of typical LCs located in the dermis of the index finger. Thus, the results of the present study contribute to an improved understanding of the function of femoral artery LCs. Anat Rec, 301:1809 1814, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30294880 TI - MiR-409-3p and MiR-1896 co-operatively participate in IL-17-induced inflammatory cytokine production in astrocytes and pathogenesis of EAE mice via targeting SOCS3/STAT3 signaling. AB - Th17 cells and interleukin-17 (IL-17) have been found to play an important role in the pathology of multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE). Response to IL-17, reactive astrocytes accompany with immune cells infiltration and axonal damage in MS/EAE. However, the role and the regulatory mechanism of IL-17-activated astrocytes in inflammation and in the EAE process still remain largely unknown. Here, we elucidated that miR-409-3p and miR-1896, as co-upregulated microRNAs in activated astrocytes and in EAE mice, targeted suppressor of cytokine signaling proteins 3 (SOCS3). Overexpression of miR-409-3p or miR-1896 significantly reduced SOCS3 expression and increased phosphorylation of STAT3 as well as induced the inflammatory cytokines production (IL-1beta, IL-6, IP-10, MCP-1, and KC), CD4+ T cells migration and demyelination, in turn aggravating EAE development. Importantly, the effects of co-overexpression of miR-409-3p and miR-1896 in vitro or in vivo are strongly co-operative. In contrast, simultaneously silenced miR 409-3p and miR-1896 co-operatively ameliorates inflammation and demyelination in the central nervous system of EAE mice. Collectively, our findings highlight that miR-409-3p and miR-1896 co-ordinately promote the production of inflammatory cytokines in reactive astrocytes through the SOCS3/STAT3 pathway and enhance reactive astrocyte-directed chemotaxis of CD4+ T cells, leading to aggravate pathogenesis in EAE mice. Co-inhibition of miR-409-3p and miR-1896 may be a therapeutic target for treating MS and neuroinflammation. PMID- 30294882 TI - Understanding care and outcomes in adolescents and young adult with Cancer: A review of the AYA HOPE study. AB - Historically, adolescents and young adults (AYA) diagnosed with cancer have been an understudied population, and their unique care experiences, needs, and outcomes were not well understood. Thus, 10 years ago, the National Cancer Institute supported the fielding of the Adolescent and Young Adult Health Outcomes and Patient Experiences (AYA HOPE) study to address this gap. We recruited individuals diagnosed at ages 15 to 39 with germ cell, Hodgkin and non Hodgkin lymphoma, acute lymphoblastic leukemia, and sarcoma from Surveillance, Epidemiology, and End Results cancer registries into the first multicenter population-based study of medical care, physical, and mental health outcomes for AYAs with cancer in the United States. This review of the 17 published manuscripts showed low awareness of clinical trials and substantial impact of cancer on financial burden, education and work, relationships and family planning, and physical and mental health. It highlights the feasibility of a longitudinal population-based study and key lessons learned for research on AYAs with cancer in and beyond the United States. PMID- 30294883 TI - Tissue and organ decellularization in regenerative medicine. AB - The advancement and improvement in decellularization methods can be attributed to the increasing demand for tissues and organs for transplantation. Decellularized tissues and organs, which are free of cells and genetic materials while retaining the complex ultrastructure of the extracellular matrix (ECM), can serve as scaffolds to subsequently embed cells for transplantation. They have the potential to mimic the native physiology of the targeted anatomic site. ECM from different tissues and organs harvested from various sources have been applied. Many techniques are currently involved in the decellularization process, which come along with their own advantages and disadvantages. This review focuses on recent developments in decellularization methods, the importance and nature of detergents used for decellularization, as well as on the role of the ECM either as merely a physical support or as a scaffold in retaining and providing cues for cell survival, differentiation and homeostasis. In addition, application, status, and perspectives on commercialization of bioproducts derived from decellularized tissues and organs are addressed.

AB - Blood transfusion is oftentimes required for patients suffering from acute trauma or undergoing surgical procedures in order to help maintain the body's oxygen levels. The continued demand worldwide for blood products is expected to put significant strain on available resources and infrastructure. Unfortunately, efforts to develop viable alternatives to human red blood cells for transfusion are generally unsuccessful. Here, a hybrid natural-synthetic nanodelivery platform that combines the biocompatibility of the natural RBC membrane with the oxygen-carrying ability of perfluorocarbons is reported. The resulting formulation can be stored long-term and exhibits a high capacity for oxygen delivery, helping to mitigate the effects of hypoxia in vitro. In an animal model of hemorrhagic shock, mice are resuscitated at an efficacy comparable to whole blood infusion. By leveraging the advantageous properties of its constituent parts, this biomimetic oxygen delivery system may have the potential to address a critical need in the clinic. PMID- 30294885 TI - Effect of sulfadiazine and trimethoprim on activated sludge performance and microbial community dynamics in laboratory-scale membrane bioreactors and sequencing batch reactors at 8 degrees C. AB - The effect of antibiotics sulfadiazine and trimethoprim on activated sludge operated at 8 degrees C was investigated. Performance and microbial communities of sequencing batch reactors (SBRs) and Membrane Bioreactors (MBRs) were compared before and after the exposure of antibiotics to the synthetic wastewater. The results revealed irreversible negative effect of these antibiotics in environmentally relevant concentrations on nitrifying microbial community of SBR activated sludge. In opposite, MBR sludge demonstrated fast adaptation and more stable performance during the antibiotics exposure. Dynamics of microbial community was greatly affected by presence of antibiotics. Bacteria from classes Betaproteobacteria and Bacteroidetes demonstrated the potential to develop antibiotic resistance in both wastewater treatment systems while Actinobacteria disappeared from all of the reactors after 60 days of antibiotics exposure. Altogether, results showed that operational parameters such as sludge retention time (SRT) and reactor configuration had great effect on microbial community composition of activated sludge and its vulnerability to antibiotics. Operation at long SRT allowed archaea, including ammonium oxidizing species (AOA) such as Nitrososphaera viennensis to grow in MBRs. AOA could have an important role in stable nitrification performance of MBR-activated sludge as a result of tolerance of archaea to antibiotics.

AB - Perfusion flow is one of the essential elements and advantages of organ-on-a-chip technology. For example, microfluidics have enabled implementation of perfusion flow and recapitulation of fluidic environment for vascular endothelial cells. The most prevalent method of implementing flow in a chip is to use a pump, which requires elaborate manipulation and complex connections, and accompanies a large amount of dead volume. Previously we devised a gravity-induced flow system which does not require tubing connections, but this method results in bidirectional flow to enable recirculation, which is somewhat different from physiological blood flow. Here, we have developed a novel microfluidic chip that enables gravity-induced, unidirectional flow by using a bypass channel with geometry different from the main channel. Human umbilical vein endothelial cells were cultured inside the chip and the effect of flow direction was examined. (c) 2018 American Institute of Chemical Engineers Biotechnol. Prog., 2018. PMID- 30294887 TI - Biogas purification via optimal microalgae growth: A literature review. AB - In this review, we compare works from the current decade that address the CO2 removal from biogas by means of microalgae. The microalgae culture process acts as a biochemical absorption process; it is potentially competitive with respect to classical and commercial absorption methods due to its additional benefits such as availing CO2 for the production of valuable microalgae biomass and being an environmentally friendly technique. Nevertheless, the low yield of biogas purification translates into the need to use optimal operation strategies that render the whole biogas production process economically feasible. A class of these strategies requires models capable of reproducing key traits of the dynamical behavior of microalgae growth. Thus, without overlooking the classical physico-chemical methods for biogas purification, our literature review addresses: (i) biogas purification via microalgae and different microalgae growth conditions, (ii) approaches that maximize microalgae growth, in order to increase CO2 -consumption, and (iii) different models that describe the representative characteristics of microalgae growth. This investigation traces a pathway to future considerations on optimal biogas purification alternatives by microalgae culture processes. (c) 2018 American Institute of Chemical Engineers Biotechnol.

AB - Research on intra-household resource allocation practices has largely ignored the role of communication within but especially beyond the household. This article shows that discussions engaged in outside of the household shed light on intra household deliberation and also contribute to an understanding of how norms are formed and used in discussions and negotiations. Using data from the website Mumsnet, and grounding our analysis in a framework that combines the literature on gender norms in allocation practices with insights from the study of online communication, we contribute to the sociological literature on household distribution in three ways: first, we show that women use discussion sites like Mumsnet to clarify and sometimes contest social norms regarding money and relationships; second, we show that users conceive the ability to communicate with partners as a source of 'relationship power' and use online discussion with other women to develop that skill; third, we argue that sites like Mumsnet provide fresh insights into household resource allocation processes. The article concludes with a broader discussion of the role of communication in household distribution and the value of online data for understanding such processes.

PMID- 30294889 TI - Assessing Escherichia coli metabolism models and simulation approaches in phenotype predictions: Validation against experimental data. AB - Over the last years, several genome-scale metabolic models (GEMs) and kinetic models of Escherichia coli were published. Their predictive performance varies according to the evaluation metric considered, the computational simulation methods used, and the type/quality of experimental data available. However, the GEM approach is often not compared with the kinetic modeling framework. Also, the different genome-scale reconstruction versions and simulation methods of mutant phenotypes are usually not validated to predict intracellular fluxes using large experimental datasets. Here, we intended to (i) systematically evaluate the prediction performance of three E. coli GEMs (iJR904, iAF1260, and iJO1366) available in the literature according to predictive growth metrics (intracellular flux distribution); (ii) assess the reliability of a E. coli GEM in the prediction of gene knockout phenotypes when different simulation methods (parsimonious flux balance analysis, Minimization of Metabolic Adjustment, linear version of MoMA, Regulatory on/off minimization, and Minimization of Metabolites Balance) are used; and finally (iii) investigate the flux distribution predictive power of the constrained-based modeling approach (selected stoichiometric GEM) and compare it with the kinetic modeling approach (two published kinetic models) for E. coli central metabolism, in order to assess their accuracy. Results show that the phenotype predictions were not significantly sensitive to the metabolic models, although the GEM iAF1260 was more accurate in the prediction of central carbon fluxes at low dilution rates. Furthermore, we observed that the choice of the appropriate simulation method of mutant phenotypes depends on the biological question to be addressed. In terms of the two modeling approaches, none outperformed the other for all the tested scenarios. (c) 2018 American Institute of Chemical Engineers Biotechnol. Prog., 2018. PMID- 30294891 TI - Inhibition of key enzymes in the inflammatory pathway by hybrid molecules of terpenes and synthetic drugs: In vitro and in silico studies. AB - The aim of this work was to compare the anti-inflammatory activity of compounds prepared from terpenes and the synthetic drugs ibuprofen and naproxen. The anti inflammatory activity of the hybrid compounds was compared with the activity of the parent compounds. This was accomplished using in vitro inhibition of lipoxygenases (LOX) and COX-2, and in silico docking studies in 15-LOX and COX-2. The synthesized hybrids showed an inhibition of COX-2 and LOX between 9.8%-57.4% and 0.0%-97.7%, respectively. None of the hybrids showed an improvement in the inhibitory effect toward these pro-inflammatory enzymes, compared to the parent terpenes and non-steroidal anti-inflammatory drugs. The docking studies allowed us to predict the potential binding modes of hybrids 6-15 within COX-2 and 15-LOX active sites. The relative affinity of the compounds inside the binding sites could be explained by forming non-covalent interactions with most important and known amino acids reported for those enzymes. A good correlation (r2 = 0.745) between docking energies and inhibition percentages against COX-2 was found. The high inhibition obtained for compound 10 against COX-2 was explained by hydrogen bond interactions at the enzyme binding site. New synthetic possibilities could be obtained from our in silico models, improving the potency of these hybrid compounds. PMID- 30294892 TI - Unequally into "Us": Characteristics of Individuals in Asymmetrically Committed Relationships. AB - This study examined characteristics of individuals that are associated with being in asymmetrically committed relationships (ACRs), defined as romantic relationships in which there was a substantial difference in the commitment levels of the partners. These ACRs were studied in a national sample of unmarried, opposite-sex romantic relationships (N = 315 couples). Perceiving oneself as having more potential alternative partners was associated with increased odds of being the less committed partner in an ACR compared to not being in an ACR, as was being more attachment avoidant, having more prior relationship partners, and having a history of extradyadic sex during the present relationship. Additionally, having parents who never married was associated with being the less committed partner in an ACR but parental divorce was not. Although fewer characteristics were associated with being the more committed partner within an ACR, more attachment anxiety was associated with increased odds of being in such a position compared to not being in an ACR. We also address how some findings change when controlling for commitment levels. Overall, the findings advance understanding of commitment in romantic relationships, particularly when there are substantial asymmetries involved. Implications for both research on asymmetrical commitment as well as practice (e.g., therapy or relationship education) are discussed. PMID- 30294893 TI - The Effect of Prior Work Experiences on the Preparation and Employment of Early Career Midwives. AB - INTRODUCTION: Strategic recruitment, preparation, distribution, and retention of US midwives requires a solid body of knowledge about midwives' education and workforce experiences. Although half of US midwifery education programs currently require or prefer prior registered nurse (RN) employment, data are lacking about whether and how these criteria influence efforts to scale up the workforce to meet reproductive care workforce shortages and maldistributions. METHODS: This cross-sectional research used an online survey, developed using the framework of Social Cognitive Career Theory. Early-career midwives were contacted through the American College of Nurse-Midwives electronic mailing list and social media during the fall of 2016. Statistical analysis allowed for linkage of data related to the following constructs: personal characteristics, prior RN employment, educational experiences, employment situations, career perceptions, and future plans. RESULTS: All participants (N = 244) were certified nurse-midwives. Compared with those without prior RN employment, midwives with prior RN employment were more likely to enroll part-time in distance programs and complete single majors or degrees. During enrollment, the 2 groups experienced the same degree of mentorship and cultural support and were similarly likely to attend 30 births and to pass the certification examination on first attempt. In the workforce, those with prior RN employment were 6 years older and more likely to work full-time. The 2 groups demonstrated no significant differences in their career perspectives or future career plans. DISCUSSION: Despite anecdotal concerns about training midwives who lack RN work experience, an individual without prior RN employment offers the workforce an employee who completes midwifery education at a younger age, may be educated more quickly, and is more likely to have earned a dual major or degree. Those with prior RN employment are more likely to work full-time. Both groups may offer benefits to education and the workforce. PMID- 30294894 TI - The tetrafascicular nature of the intraventricular conduction system. AB - The existence of a tetrafascicular intraventricular conduction system remains debatable. A consensus statement ended up with some discrepancies and, despite agreeing on the possible existence of an anatomical left septal fascicle, the electrocardiographic and vectorcardiographic characteristics of left septal fascicular block (LSFB) were not universally accepted. The most important criteria requested to confirm the existence of LSFB is its intermittent nature. So far, our group has published cases of transient ischemia-induced LSFB and phase 4 or bradycardia-dependent LSFB. Finally, anatomical, anatomopathological, histological, histopathological, electrocardiographic, vectorcardiographic, body surface potential mapping, and electrophysiology studies support the fact that the left bundle branch divides into three fascicles or a "fan-like interconnected network". PMID- 30294895 TI - Data-driven multi-objective optimization via grid compatible simplex technique and desirability approach for challenging high throughput chromatography applications. AB - Recently, a grid compatible Simplex variant has been demonstrated to identify optima consistently and rapidly in challenging high throughput (HT) applications in early bioprocess development. Here, this method is extended by deploying it to multi-objective optimization problems. Three HT chromatography case studies are presented, each posing challenging early development situations and including three responses which were amalgamated by the adoption of the desirability approach. The suitability of a design of experiments (DoE) methodology per case study, using regression analysis in addition to the desirability approach, was evaluated for a large number of weights and in the presence of stringent and lenient performance requirements. Despite the adoption of high-order models, this approach had low success in identification of the optimal conditions. For the deployment of the Simplex approach, the deterministic specification of the weights of the merged responses was avoided by including them as inputs in the formulated multi-objective optimization problem, facilitating this way the decision making process. This, and the ability of the Simplex method to locate optima, rendered the presented approach highly successful in delivering rapidly operating conditions, which belonged to the Pareto set and offered a superior and balanced performance across all outputs compared to alternatives. Moreover, its performance was relatively independent of the starting conditions and required sub-minute computations despite its higher order mathematical functionality compared to DoE techniques. These evidences support the suitability of the grid compatible Simplex method for early bioprocess development studies involving complex data trends over multiple responses.

PMID- 30294896 TI - Comparison of BMI, waist circumference, and waist-to-height ratio for identification of subclinical cardiovascular risk in pediatric kidney transplant recipients. AB - BACKGROUND: Kidney transplant recipients are at high risk for CV morbidity. However, the measure of obesity that best predicts CV risk has not been established. OBJECTIVE: A prospective, controlled study was conducted to compare the ability of BMI, WC, and WHr to identify CV risk in pediatric kidney transplant recipients. METHODS: Transplant recipients, aged 3-20 years, had echocardiogram, CIMT, BMI, WC, WHr, blood pressure, lipids, and leptin measured. Receiver operating characteristic analysis was used to compare the ability of BMI, WC, and WHr to detect a composite adverse CV outcome. Presence of the composite outcome was defined by >=3 of the following five criteria: (a) LVH, (b) high CIMT, (c) impaired myocardial strain, (d) dyslipidemia, and/or (e) hypertension. Multivariate analysis was conducted by generalized estimating equation regression. RESULTS: We analyzed 108 visits of 42 transplant recipients. Prevalence of obesity by WHr (43.5%) was higher than BMI (24.1%) and WC (12.0%). Proportion of WHr-obese who met criteria for the adverse CV outcome was higher (62.2%) than BMI (34.6%) and WC-obese (33.3%). Leptin levels were higher in children with obesity. Area under the ROC curve for WHr-obese (0.77) was higher compared to BMI (0.47) and WC (0.48) to detect the CV outcome, P = 0.0006. WHr obesity was associated with 5.72 increased odds of having the adverse CV outcome, P = 0.0001, while BMI and WC were not significant. CONCLUSION: WHr is more sensitive than BMI or WC to detect subclinical CV risk and should be included in screening of pediatric kidney transplant recipients. PMID- 30294897 TI - The risk of venous thromboembolism during and after hospitalisation in patients with inflammatory bowel disease activity. AB - BACKGROUND: Inflammatory bowel disease (IBD) increases the risk of venous thromboembolism. AIMS: To determine when patients are at high risk of thromboembolic events, including after major surgery, and to guide timing of thromboprophylaxis. METHODS: Each IBD patient from Clinical Practice Research Datalink, linked with Hospital Episode Statistics, was matched to up to five non IBD patients in this cohort study. We examined their risk of thromboembolism in hospital and within 6 weeks after leaving hospital, with or without undergoing major surgery, and while ambulant. Hazard ratios were estimated using Cox regression, with adjustment for age, sex, body mass index, smoking and history of malignancy or thromboembolism. RESULTS: Overall 23 046 IBD patients had a thromboembolic risk 1.74-times (95% CI = 1.55-1.96) higher than 106 795 non-IBD patients. Among ambulant patients, the thromboembolic risk was raised during acute (hazard ratio = 3.94, 2.79-5.57) or chronic disease activity (3.97, 2.90 5.45) but their absolute risk remained below 5/1000 person-years. The hazard ratio for thromboembolism among in-patients not undergoing major surgery was 1.13 (0.63-2.02), compared to 2.43 (1.20-4.92) among surgical patients, with a near doubling of absolute risk associated with surgery (59.5/1000 person-years, compared with 31.1 without surgery). The absolute risk remained elevated within 6 weeks after leaving hospital (18.6/1000 person-years in IBD patients after surgery). CONCLUSIONS: IBD patients are at an increased risk of venous thromboembolism. Absolute risks are raised during active disease, when in hospital, and after leaving hospital following major surgery. PMID- 30294898 TI - Direct Measurement of Electronic Band Structure in Single Quantum Dots of Metal Chalcogenide Composites. AB - Metal chalcogenide quantum dots (QDs) are among the most promising materials as light harvesters in all-inorganic systems for applications in solar cells and production of solar fuels. The electronic band structure of composite QDs formed by lead and cadmium chalcogenides directly grafted on highly oriented pyrolytic graphite surfaces through successive ionic layer absorption and reaction is investigated. Atomic force microscopy and Kelvin probe force microscopy (KPFM) are applied to investigate PbS, CdS, and PbS/CdS QD systems. The variation of the surface potential of individual QDs is measured, investigating the evolution of the electronic band structure as a function of QD size and composition. A shift of the Fermi level toward more negative values occurs when QD size is increased. The shift is more pronounced in CdS than in PbS, while the composite PbS/CdS exhibits an intermediate behavior. The calculated shift is in good agreement with the experiments. These results highlight the ability of KPFM to directly measure the electronic band structure in individual QDs of metal chalcogenide composites. This feature regulates charge dynamics in composite systems, thereby affecting device performance. This work provides valuable insights for applications in several fields, in which charge injection plays a major role. PMID- 30294899 TI - Discovery of Elusive K4 O6 , a Compound Stabilized by Configurational Entropy of Polarons. AB - Synthesis of elusive K4 O6 has disclosed implications of crucial relevance for new solid materials discovery. K4 O6 forms in equilibrium from K2 O2 and KO2 , in an all-solid state, endothermic reaction at elevated temperature, undergoing back reaction upon cooling to ambient conditions. This tells that the compound is stabilized by entropy alone. Analyzing possible entropic contributions reveals that the configurational entropy of "localized" electrons, i.e., of polaronic quasi-particles, provides the essential contribution to the stabilization. We corroborate this assumption by measuring the relevant heats of transformation and tracking the origin of entropy of formation computationally. These findings challenge current experimental and computational approaches towards exploring chemical systems for new materials by searching the potential energy landscape: one would fail in detecting candidates that are crucially stabilized by the configurational entropy of localized polarons. PMID- 30294900 TI - Hydrogen sulfide suppresses ghrelin secretion in vitro and delays postprandial ghrelin secretion while reducing appetite in mice. AB - Ghrelin is a stomach-derived hormone that regulates several metabolic functions including growth hormone release, appetite, adiposity, and gastric motility. Nutrients, the autonomic nervous system, and other metabolic hormones have all been implicated in the regulation of ghrelin secretion. Despite this, ongoing efforts to develop modulators of ghrelin secretion in human diseases are still underway. Hydrogen sulfide (H2 S) is a gaseous signaling molecule that is produced both endogenously in many tissues and by the gut microbiome. H2 S has established roles in cardiovascular and immune health, however, more recently H2 S has been implicated in the regulation of metabolic hormone secretion. We hypothesized that H2 S is able to directly regulate ghrelin secretion and in turn, regulate appetite. We first demonstrated that GYY4137 (an H2 S donor molecule) directly suppresses ghrelin secretion in rat primary gastric culture, in part through the activation of the protein kinase B (AKT) pathway. We then demonstrated the colocalization of ghrelin-positive gastric cells with the H2 S producing enzyme cystathionine-gamma-lyase (CSE). While GYY4137 suppressed ghrelin secretion, inhibition of CSE caused a stimulation in ghrelin secretion in primary gastric culture. In mice, GYY4137 treatment prolonged the postprandial drop of circulating ghrelin and caused reduced food consumption up to 4 h after treatment. These results demonstrate for the first time a role for H2 S in the regulation of ghrelin and appetite. Modulating H2 S levels may be a novel approach to regulate ghrelin secretion in the treatment of metabolic diseases. PMID- 30294901 TI - Rapamycin and FK506 derivative TH2849 could ameliorate neurodegenerative diseases through autophagy with low immunosuppressive effect. AB - Autophagy is an essential cellular process concern with cellular homeostasis down regulated by mTOR, whose activity can be modulated by rapamycin, a kind of lipophilic macrolide antibiotic, through forming a complex with immunophilin FKBP12 essential for mTOR regulation to induce autophagy. Therefore, rapamycin is normally used as a neuron protective agent. The immunophilin FKBP12 binding ligand FK506 is well known as an immunosuppressive agent by inhibiting the calcineurin expression. In this study, we synthesized a series of modified compounds based on the FKBP12 binding moiety to as same as the binding structure of rapamycin and FK506 particularly. We removed the other binding regions of the complex that has the property of immunosuppression. We found that a novel small molecule named TH2849 from these derivative compounds has a significant binding connection with mTOR by comparing to calcineurin. The effects of TH2849 on calcineurin/NFAT were not as significant as FK506, and weak effects on IL2/p34cdc2 /cyclin signaling pathway were also found. Moreover, TH2849 also shows mitochondrial protective effect through stabilizing the mitochondrial structure and transmembrane potential (DeltaPsim) and could rescue dopaminergic neurons in MPTP-treated zebrafishes as well as mice models with less immunosuppressive effect. Our present study shows that TH2849 works as a neuroprotective agent possibly by inducing autophagy and low immunosuppressive effect. PMID- 30294902 TI - A comparison of the influence of three different lumbar interbody fusion approaches on stress in the pedicle screw fixation system: Finite element static and vibration analyses. AB - This study aimed to examine breakage risk of the bilateral pedicle screw (BPS) fixation system under static and vibration loadings after three different types of lumbar interbody fusion surgery. A previously validated intact L1-sacrum finite element model was modified to simulate anterior, posterior, and transforaminal lumbar interbody fusion (ALIF, PLIF, and TLIF, respectively) with BPS fixation system (consisting of pedicle screws and rigid connecting rods) at L4-L5. As a risk parameter for breakage, the von Mises stresses in the pedicle screws and the rods for the ALIF, PLIF, and TLIF models under static loading (flexion, extension, lateral bending, and axial torsion moments) and vibration loading (sinusoidal vertical load) were calculated and compared. The calculated von Mises stresses were different in the ALIF, PLIF, and TLIF models, but these stresses for all the fusion models were found to be concentrated in neck of the pedicle screw and middle of the rod under both the static and vibration loadings. The results from static analyses showed that the maximum stress in the BPS fixation system was greater in the TLIF model than in the ALIF and PLIF models under all the applied static loadings. The results from transient dynamic analyses also showed that the TLIF generated greater dynamic responses of the stress in the BPS fixation system to the vertical vibration compared with the ALIF and PLIF. It implies that the TLIF procedure might incur a higher risk of breakage for the BPS fixation system than the ALIF and PLIF procedures. PMID- 30294903 TI - Efficacy of interventions led by staff with geriatrics expertise in reducing hospitalisation in nursing home residents: A systematic review. AB - OBJECTIVE: To determine the efficacy of interventions, delivered by geriatrics trained staff for nursing home residents, in reducing hospitalisation. METHODS: Multiple databases and clinical trial registers were searched. Studies that provided comparative data and involved residents aged >=65 years evaluating patient-level interventions delivered by geriatrics-trained staff were included. The systematic review protocol was made available on PROSPERO (registration number CRD42017079928; www.crd.york.ac.uk/PROSPERO). RESULTS: Sixteen studies were included; six were randomised controlled trials. Studies were categorised according to intervention approaches into the following: (i) hospital prevention program; (ii) emergency department-based hospital avoidance program; and (iii) post-hospital supported discharge program. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) quality of evidence was low to moderate. Most studies demonstrated a favourable trend; however, only a few reported statistically significant reductions in hospitalisations. Results from the randomised studies were non-significant. CONCLUSIONS: Despite the heterogeneity of studies, there is limited evidence that interventions delivered by geriatrics-trained staff reduce hospitalisations in nursing home residents. Further work examining decision-making around hospital transfer may help inform future intervention design. PMID- 30294904 TI - Bone marrow mesenchymal stem cells stimulated with low-intensity pulsed ultrasound: Better choice of transplantation treatment for spinal cord injury: Treatment for SCI by LIPUS-BMSCs transplantation. AB - Stem cell transplantation, especially treatment with bone marrow mesenchymal stem cells (BMSCs), has been considered a promising therapy for the locomotor and neurological recovery of spinal cord injury (SCI) patients. However, the clinical benefits of BMSCs transplantation remain limited because of the considerably low viability and inhibitory microenvironment. In our research, low-intensity pulsed ultrasound (LIPUS), which has been widely applied to clinical applications and fundamental research, was employed to improve the properties of BMSCs. The most suitable intensity of LIPUS stimulation was determined. Furthermore, the optimized BMSCs were transplanted into the epicenter of injured spinal cord in rats, which were randomized into four groups: (a) Sham group (n = 10), rats received laminectomy only and the spinal cord remained intact. (b) Injury group (n = 10), rats with contused spinal cord subjected to the microinjection of PBS solution. (c) BMSCs transplantation group (n = 10), rats with contused spinal cord were injected with BMSCs without any priming. (d) LIPUS-BMSCs transplantation group (n = 10), BMSCs stimulated with LIPUS were injected at the injured epicenter after contusion. Rats were then subjected to behavioral tests, immunohistochemistry, and histological observation. It was found that BMSCs stimulated with LIPUS obtained higher cell viability, migration, and neurotrophic factors expression in vitro. The rate of apoptosis remained constant. After transplantation of BMSCs and LIPUS-BMSCs postinjury, locomotor function was significantly improved in LIPUS-BMSCs transplantation group with higher level of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in the epicenter, and the expression of neurotrophic receptor was also enhanced. Histological observation demonstrated reduced cavity formation in LIPUS-BMSCs transplantation group when comparing with other groups. The results suggested LIPUS can improve BMSCs viability and neurotrophic factors expression in vitro, and transplantation of LIPUS-BMSCs could promote better functional recovery, indicating possible clinical application for the treatment of SCI. PMID- 30294905 TI - Alteration of serum and tissue tumor necrosis factor alpha levels: A possible mechanism of action of oral pulse steroids in the treatment of alopecia areata. AB - BACKGROUND: Alopecia areata (AA) is a multifactorial disease in which tumor necrosis factor alpha (TNF-alpha) plays an important role. OBJECTIVE: To study the effect of oral pulse steroids on both serum and tissue levels of TNF-alpha in AA patients. METHODS: Skin biopsies and serum samples were collected from 20 patients with patchy AA before and after treatment (oral prednisolone for two consecutive days every week for 3 months) for determination of the levels of TNF alpha levels using ELISA technique. RESULTS: Both serum and tissue levels of TNF alpha in AA patients were significantly higher than in controls before (P < 0.001) as well as after treatment (P = 0.0169 and P = 0.3051), respectively. The duration of disease negatively correlated with tissue TNF-alpha before treatment (P < 0.0001). Serum and tissue levels of TNF-alpha dropped significantly after treatment (P < 0.0001). The percentage of reduction of both tissue and serum TNF alpha levels correlated positively with the percentage of clinical improvement (r = 0.682, P = 0.0009; r = 0.567, P = 0.009, respectively). CONCLUSION: TNF-alpha plays an important role in the evolution of AA lesions, and alteration in both serum and tissue levels of TNF-alpha could be considered one of the important mechanisms of action of systemic oral pulse steroids in the treatment of AA.

PMID- 30294906 TI - N-acetylcysteine targets 5 lipoxygenase-derived, toxic lipids and can synergize with prostaglandin E2 to inhibit ferroptosis and improve outcomes following hemorrhagic stroke in mice. AB - OBJECTIVES: N-acetylcysteine (NAC) is a clinically approved thiol-containing redox modulatory compound currently in trials for many neurological and psychiatric disorders. Although generically labeled as an "antioxidant," poor understanding of its site(s) of action is a barrier to its use in neurological practice. Here, we examined the efficacy and mechanism of action of NAC in rodent models of hemorrhagic stroke. METHODS: Hemin was used to model ferroptosis and hemorrhagic stroke in cultured neurons. Striatal infusion of collagenase was used to model intracerebral hemorrhage (ICH) in mice and rats. Chemical biology, targeted lipidomics, arachidonate 5-lipoxygenase (ALOX5) knockout mice, and viral gene transfer were used to gain insight into the pharmacological targets and mechanism of action of NAC. RESULTS: NAC prevented hemin-induced ferroptosis by neutralizing toxic lipids generated by arachidonate-dependent ALOX5 activity. NAC efficacy required increases in glutathione and is correlated with suppression of reactive lipids by glutathione-dependent enzymes such as glutathione S transferase. Accordingly, its protective effects were mimicked by chemical or molecular lipid peroxidation inhibitors. NAC delivered postinjury reduced neuronal death and improved functional recovery at least 7 days following ICH in mice and can synergize with clinically approved prostaglandin E2 (PGE2 ). INTERPRETATION: NAC is a promising, protective therapy for ICH, which acted to inhibit toxic arachidonic acid products of nuclear ALOX5 that synergized with exogenously delivered protective PGE2 in vitro and in vivo. The findings provide novel insight into a target for NAC, beyond the generic characterization as an antioxidant, resulting in neuroprotection and offer a feasible combinatorial strategy to optimize efficacy and safety in dosing of NAC for treatment of neurological disorders involving ferroptosis such as ICH.

AB - OBJECTIVE: To describe 4 cases of tracheal narrowing attributed to tracheal mucosal hemorrhage caused by anticoagulant rodenticide toxicity in breeds predisposed to tracheal collapse. CASE SUMMARY: Over the years 2005-2014, 4 dogs were presented for respiratory distress secondary to diffuse tracheal narrowing. All dogs had possible anticoagulant rodenticide ingestion and prolonged prothrombin time. All dogs received fresh-frozen plasma transfusions, vitamin K1 supplementation, and supportive care. Tracheal narrowing improved on follow-up radiographs in 3 of 4 patients. One of 4 did not have follow-up radiographs performed. All dogs survived. NEW OR UNIQUE INFORMATION PROVIDED: Anticoagulant rodenticide toxicity causing clinical signs consistent with tracheal collapse is a rare but recognized phenomenon that has not been previously reported in breeds prone to tracheal collapse. PMID- 30294909 TI - Vertebral column deformity in adult wild haddock (Melanogrammus aeglefinus). AB - This study describes radiological malformations in the vertebral column of adult sexually mature wild haddock, Melanogrammus aeglefinus collected from Masfjorden, Western Norway, in 2014 and 2015. There were seven deformed fish (33% of sampled fish), five with mild deformities and two with severe deformities. The deformity types discovered were lordosis, vertebra body asymmetry, compression, fusion (ankylosis), remodelling, and haemal spine hyperostosis. The two severely deformed fish were as follows: (a) one specimen with 29 deformed vertebrae within the region vertebrae nos. 1-30, including two sites of lordosis; (b) one specimen with 15 deformed vertebrae within the region vertebrae nos. 31-52 (most caudal vertebrae). The results of this study show that wild haddock can survive severe vertebra deformities, both in the trunk and tail region, and reach adulthood and sexual maturity. Whether normal nondeformed wild conspecifics would mate and spawn with these individuals and thereby complete the life cycle of the deformed individuals is, however, unknown. A possible link between bone fracture and fish hyperostosis is discussed. PMID- 30294910 TI - Cardiovascular disease and other childhood-onset chronic conditions in adults with cerebral palsy. PMID- 30294911 TI - CD36 is indispensable for nutrient homeostasis and endurance exercise capacity during prolonged fasting. AB - During fasting, most tissues including skeletal muscle heavily rely on utilization of fatty acids (FA) and minimize glucose use. In contrast, skeletal muscle prefers carbohydrate use as exercise intensity increases. In mice deficient for CD36 (CD36-/- mice), FA uptake is markedly reduced with a compensatory increase in glucose uptake in skeletal muscle even during fasting. In this study, we questioned how exercise endurance is affected during prolonged fasting in CD36-/- mice where glucose utilization is constantly increased. With or without a 24-h fast, a single bout of treadmill exercise was started at the speed of 10 m/min, and the speed was progressively increased up to 30 m/min until mice were exhausted. Running distance of wild type (WT) and CD36-/- mice was comparable in the fed state whereas that of CD36-/- mice was significantly reduced after a 24-h fast. Glycogen levels in liver and skeletal muscle were depleted both in WT and CD36-/- mice after a 24-h fast. In CD36-/- mice, FA uptake by skeletal muscle continued to be reduced during fasting. Glucose utilization also continued to be enhanced in the heart and oxidative skeletal muscle and glucose supply relative to its demand was diminished, resulting in accelerated hypoglycemia. Consequently, available energy substrates from serum and in muscle for exercise performance were very limited in CD36-/- mice during prolonged fasting, which could cause a remarkable reduction in exercise endurance. In conclusion, our study underscores the importance of CD36 for nutrient homeostasis to maintain exercise performance of skeletal muscle when nutrient supply is limited. PMID- 30294912 TI - Microbial contamination in methanol biofilters inoculated with a pure strain of Pichia pastoris: A potential limitation for waste revalorization. AB - Novel biotechnologies to valorize waste emissions are based on the use of specialized microbial groups that produce different compounds of industrial interest. On this scenario, the retention of such specific microorganisms in the system is of critical interest; however, the potential limitations of working with simplified cultures in a competitive open environment are neither fully explored nor well understood. In this work, a series of biofilters treating methanol vapors coupled with heterologous endochitinase production were used to evaluate the performance of a specialized microbial population during a typical open-to-environment operation. The biofilters were inoculated with a transformed strain of Pichia pastoris and were operated identically for about 90 days. The results showed that the biofiltration performance became diverse with time in terms of the elimination capacity (EC) shifting from a variation coefficient of 1.5% (EC = 274 +/- 24, 279 +/- 5, and 281.9 +/- 25 g/[m3 h]) at the beginning of the operation to 33% (EC = 297 +/- 9, 338 +/- 7, and 341 +/- 2 g/[m3 h]) at the end of operation. Epifluorescence analysis and cloning-sequencing suggested that P. pastoris remained as the dominant microorganism of methanol degradation, whereas diverse airborne bacteria, including Ochrobactrum spp. and Klebsiella oxytoca, played a secondary role possibly associated with the consumption of intermediates. Overall, this study found that low diversity systems operated under non-sterile conditions could be susceptible to contamination with external microorganisms causing a diversifying behavior at the performance and microbial community levels.

PMID- 30294913 TI - The long non-coding RNA MALAT1 promotes ovarian cancer progression by regulating RBFOX2-mediated alternative splicing. AB - Ovarian cancer metastasizes via direct seeding, whereby cancer cells shed from the primary site, resist cell death in the peritoneal cavity, then metastasize to peritoneal organs. We sought to identify molecular mechanisms that facilitate ovarian cancer cell anchorage independent survival. Gene expression profiling was performed on ovarian cancer cells grown in attached or forced suspension culture and confirmed by RT-qPCR. Anoikis was measured by Caspase 3/7 assay. Since the long non-coding RNA Metastasis Associated Lung Adenocarcinoma transcript 1 (MALAT1) was among the transcripts most highly increased in forced suspension culture, modified anti-sense oligonucleotides (ASO) were used to inhibit its expression. Knockdown of RBFOX2 and KIF1B was performed using shRNAs. Publically available datasets were analyzed for association of MALAT1 gene expression with clinicopathological variables. In multiple anoikis-resistant ovarian cancer cell lines MALAT1 expression increased after 24 and 48 h in forced suspension culture compared to attached culture. High MALAT1 is associated with increased stage, recurrence, and reduced survival in ovarian cancer, and in a small percentage of ovarian cancers MALAT1 is amplified. MALAT1 knockdown resulted in decreased proliferation, invasion, anchorage-independent growth, and increased anoikis. Suppression of MALAT1 also resulted in decreased expression of RBFOX2, and alternative processing of the pro-apoptotic tumor suppressor gene KIF1B. RBFOX2 suppression resulted in preferential splicing of the pro-apoptotic isoform of KIF1B (KIFB1B-beta) and increased anoikis. The lncRNA MALAT1 facilitates a pro metastatic phenotype in ovarian cancer by promoting alternative RNA processing and differential expression of anti-apoptosis and epithelial to mesenchymal transition (EMT)-related genes. PMID- 30294914 TI - A role for surgery in the treatment of relapsed Hodgkin lymphoma. AB - Treatment of Hodgkin lymphoma (HL) has advanced over time, rendering a fatal disease now largely curable. Multiagent chemotherapy regimens, hematopoietic stem cell transplantation, and radiotherapy are the mainstays of care. Surgical intervention is rarely indicated other than for biopsy at diagnosis. However, for patients with recurrent relapsed HL isolated to one anatomical location, refractory to all other therapy, there may be a beneficial role for surgical excision. Herein, we report the surgical management of three relapsed patients with stage IVB HL who were refractory to multiple other therapeutic approaches, who all achieved good event-free survival after operative management. PMID- 30294915 TI - Hedgehog-Like Gold-Coated Magnetic Microspheres that Strongly Inhibit Tumor Growth through Magnetomechanical Force and Photothermal Effects. AB - Using magnetomechanical force to kill cancer cells has attracted great attention recently. This study presents novel hedgehog-like microspheres composed of needle like magnetic nanoparticles with carbon and gold double shells. Using a novel low frequency vibrating magnetic field (VMF), these microspheres with sharp surfaces can seriously damage cancer cells and strongly inhibit mouse tumor growth through mechanical force. The cell killing efficiency depends on VMF exposure time, frequency, strength, and microsphere concentration. The maximum mechanical force generated by one microsphere acting on a cancer cell under a VMF is about 35.79 pN. The microspheres also induce photothermal ablation after being triggered by near-infrared laser irradiation. Mouse tumors could not be detected after treatment with the synergistic stimuli of mechanical force and photothermal ablation. These results reveal a simple and highly efficient strategy using magnetic microspheres for local treatment of solid tumors in a remote and noninvasive manner.

The proteinaceous components of Ap silk proteins, namely fibroin and sericin may represent an alternative over mulberry Bombyx mori silk proteins. In fact, the silk fibroin (SF) of Ap is rich in Arginyl-Glycyl-Aspartic acid (RGD) peptides, which facilitate the adhesion and proliferation of various cell types. The possibility of processing Ap silk proteins into different distinct 2D- and 3D based matrices is described in earlier studies, such as membranes, nanofibers, scaffolds, and micro/nanoparticles, contributing to a different rate of degradation, mechanical properties, and biological performance useful for various biomedical applications. This review summarizes the current advances and developments on nonmulberry Chinese oak tasar silk protein (fibroin and sericin) based biomaterials and their potential uses in tissue engineering, regenerative medicine, and therapeutic delivery strategies.

AB - Although spinal injuries in fish have been associated with electric stimuli applied during electrofishing and electrotrawling, bone fracture and repair in the axial skeleton have yet not been studied. To study this, we radiographed a group (n = 64) of individually tagged farmed cod twice, with a 1-year interval (~36 cm at first and ~ 50 cm at second inspection). The study focus was on the neural and haemal spines. These structures are un-paired and are not covered by other bones laterally, making them useful for radiological studies on axial skeletal fracture in live fish. At the first examination, four animals showed radiological changes in their neural and haemal spines. Two animals had fractures, and two had callus formations. One year later, at the second radiological examination, the fractures had developed into calluses or into normal morphology, and calluses either remained as calluses or had developed into normal morphology. A further 14 animals that were all normal at the first inspection had developed changes in their neural and haemal spines, both fractures and callus formations. This is the first record of spontaneous bone fracture in fish; the fractures observed occurred under normal farming conditions and were not induced. The results show that cod have a functional fracture healing mechanism in their neural and haemal spines. The findings are discussed in relation to fish hyperostosis.

PMID- 30294921 TI - Primary cutaneous lymphoma in Argentina: a report of a nationwide study of 416 patients. AB - BACKGROUND: The aim of this study was to determine the relative frequency of primary cutaneous lymphoma (PCL) in Argentina according to the new World Health Organization (WHO)-European Organization for the Research and Treatment of Cancer (EORTC) classification system. METHODS: A total of 416 patients from 21 dermatology services were included during a 5-year period (2010-2015); these patients were classified using WHO-EORTC criteria. RESULTS: There were 231 (55.2%) males and 185 (44.8%) females; the male-to-female ratio was 1.35. The median age of the patients was 57 years (range, 0-90 years). Most patients were Caucasian (79%), and only 16% of patients were registered as Amerindian. Most patients (387/416, 93%) had cutaneous T-cell lymphoma (CTCL); 28 patients (6.7%) were diagnosed with cutaneous B-cell lymphoma (CBCL). The most frequent CTCL subtypes, in decreasing order of prevalence, were mycosis fungoides (MF), including its variants (75.7%); CD30+ primary cutaneous lymphoproliferative disorders (7.2%); and Sezary syndrome (SS) (3.1%). Cutaneous follicle center lymphoma was the most common CBCL subtype (2.9%). In the subset of patients <=20 years of age, the most common condition was MF (57%), followed by extranodal NK-T nasal-type lymphoma (14%). CONCLUSIONS: This study revealed relatively higher rates of MF and lower rates of CBCL in Argentinean patients that have been reported in American and European countries. PMID- 30294922 TI - Re-Evaluating the Assistant Practitioner Role in NHS England: Survey Findings. AB - AIM AND BACKGROUND: In the absence of data providing an overview on the state of the assistant practitioner (AP) workforce, this study surveys trusts in NHS England with the aim of establishing how the role is viewed, used and managed. METHODS: Based on an earlier survey undertaken around a decade ago, an online questionnaire was sent to members of an assistant practitioner network, generating a response from over fifty different trusts, drawn from different regions and healthcare settings. RESULTS: The survey results highlight the increased use of assistant practitioners by trusts and in a more diverse range of clinical settings. This increase has been driven more by the apparent value of the APs in addressing issues of service design and quality, than by attempts to reduce costs through substitution and skill mix dilution. CONCLUSIONS: The AP role has retained value to nurse managers in developing and designing services, and indeed in establishing a career pathway for healthcare assistants. Most striking are future intentions to continue using APs, particularly within the context of the emerging nursing associate (NA) role. This suggests that the AP and NA are likely to be complementary rather than alternative roles. IMPLICATIONS FOR NURSING MANAGERS: Nurse managers might note the continuing use and value of the AP role, although as means of improving design and quality as well as providing career opportunities for healthcare assistants, rather than as a way of saving labour costs. Clearly the AP role has a future although there is scope to review its position in relation to the newly emerging nurse associate role. This article is protected by copyright. All rights reserved. PMID- 30294924 TI - Prevalence and clinical characteristics of refractoriness to optimal proton pump inhibitor therapy in non-erosive reflux disease. AB - BACKGROUND: The real size of the gastro-oesophageal reflux disease (GERD) population not responding to proton pump inhibitor (PPI) therapy has still not been fully elucidated. Causes of PPI refractoriness include incorrect diagnosis and lack of adherence to therapy, in terms of incorrect dosage and timing. AIMS: To evaluate the prevalence of refractoriness to optimal PPI therapy and the contribution of non-erosive reflux disease (NERD), reflux hypersensitivity, and functional heartburn, to PPI refractoriness. The association of functional GI symptoms in non-responders was evaluated. METHODS: Frequency and severity of GERD symptoms (heartburn, regurgitation, chest pain), dysphagia, belching, epigastric pain, postprandial distress, irritable bowel syndrome (IBS), globus, and ear nose and throat (ENT) symptoms were evaluated in patients previously classified as non responders. Patients with at least one of the oesophageal symptoms with a frequency >=3 /week were treated with esomeprazole 40 mg once daily for 8 weeks and then re-evaluated. Non-responders (patients with oesophageal symptoms >=3 times per week) underwent 24 hour multichannel intraluminal impedance-pH monitoring. RESULTS: Of 573 consecutive patients, 92 with oesophageal symptoms and classified as PPI-refractory underwent the esomeprazole trial; 60 did not respond. IBS, epigastric pain, and post-prandial distress episodes were associated with a poor response on multivariate analysis. NERD, reflux hypersensitivity, and functional heartburn patients constituted 32%, 42%, and 26%, respectively of the PPI-refractory group. CONCLUSIONS: True refractoriness in patients with GERD symptoms attending a secondary care setting is lower than previously reported. Following a careful history and optimal PPI dosing, the rate of refractoriness was 20%. True NERD constitutes only a third of the PPI refractory group. PMID- 30294925 TI - Increased risk of mycotic infections associated with sodium-glucose co transporter 2 inhibitors: a prescription sequence symmetry analysis. AB - AIMS: To determine the risk of mycotic infections associated with the use of sodium-glucose co-transporter 2 inhibitors (SGLT2i) in a real-world setting. METHODS: We conducted a prescription sequence symmetry analysis using data from Truven Health MarketScan (2009-2015). We selected continuously enrolled patients newly initiating both an SGLT2i and an antifungal between 1 April 2013 and 31 December 2015 within time periods of 30, 60, 90, 180 or 365 days of each other. Adjusted sequence ratios (ASR) were calculated for each time period as the ratio of patients initiating SGLT2i first over those initiating an antifungal first adjusted for time trends in prescribing. Analyses were stratified by sex and type of SGLT2i. RESULTS: There were 23 276 patients who newly initiated both SGLT2i and an antifungal in our study period. These patients were further classified into those initiating the two drugs within 365 (n = 17 504), 180 (n = 11 873), 90 (n = 7697), 60 (n = 5856) or 30 (n = 3650) days of each other. Increased risks of mycotic infections were present across all time periods, with the strongest effect observed in the 90-day interval [ASR 1.53 (confidence interval, CI 1.43 1.60)]. Findings differed by sex [90-day ASR females: 1.65 (CI 1.56-1.74); males 1.25 (CI 1.14-1.36)] and by SGLT2i [90-day ASR canagliflozin 1.57 (CI 1.49-1.66); non-canagliflozin 1.42 (CI 1.31-1.55)]. CONCLUSION: Initiation of SGLT2i was associated with an increased risk for mycotic infections. Findings from this commercially insured population in the real world are consistent with evidence available from clinical trials. PMID- 30294923 TI - Mitochondrial dysfunction and increased glycolysis in prodromal and early Parkinson's blood cells. AB - BACKGROUND: Although primarily a neurodegenerative process, there is increasing awareness of peripheral disease mechanisms in Parkinson's disease. To investigate disease processes in accessible patient cells, we studied peripheral blood mononuclear cells in recently diagnosed PD patients and rapid eye movement-sleep behavior disorder patients who have a greatly increased risk of developing PD. We hypothesized that peripheral blood mononuclear cells may recapitulate cellular pathology found in the PD brain and investigated these cells for mitochondrial dysfunction and oxidative stress. METHODS: Peripheral blood mononuclear cells were isolated and studied from PD patients, rapid eye movement-sleep behavior disorder patients and age- and sex-matched control individuals from the well characterized Oxford Discovery cohort. All participants underwent thorough clinical assessment. RESULTS: Initial characterization showed that PD patients had elevated levels of CD14 + monocytes and monocytes expressing C-C motif chemokine receptor 2. Mitochondrial dysfunction and oxidative stress were increased in PD patient peripheral blood mononuclear cells, with elevated levels of mitochondrial reactive oxygen species specifically in patient monocytes. This was combined with reduced levels of the antioxidant superoxide dismutase in blood cells from PD patients and, importantly, also in rapid eye movement-sleep behavior disorder patients. This mitochondrial dysfunction was associated with a concomitant increase in glycolysis in both PD and rapid eye movement-sleep behavior disorder patient blood cells independent of glucose uptake or monocyte activation. CONCLUSIONS: This work demonstrates functional bioenergetic deficits in PD and rapid eye movement-sleep behavior disorder patient blood cells during the early stages of human disease.

PMID- 30294927 TI - Co-administration of nuciferine reduces the concentration of metformin in liver via differential inhibition of hepatic drug transporter OCT1 and MATE1. AB - Nuciferine (NF), one of the main and effective components in Nelumbo nucifera Gaertn. leaf extracts, is a promising drug candidate for the treatment of obesity related diseases, while metformin is a first line therapeutic drug for type 2 diabetes mellitus. Since nuciferine and metformin are likely to be co administered, the aim of the present study was to evaluate whether co administration of nuciferine would influence the liver (target tissue) distribution and the anti-diabetic effect of metformin by inhibiting hepatic organic cation transporter 1 (OCT1) and multidrug and toxin extrusion 1 (MATE1). The data demonstrated that nuciferine significantly reduced metformin accumulation in MDCK cells stably expressing human OCT1 (MDCK-hOCT1) or hMATE1 (MDCK-hMATE1), and primary cultured mouse hepatocytes. Furthermore, the presence of nuciferine in the basal compartment caused a concentration-dependent reduction of intracellular metformin accumulation in MDCK-hOCT1/hMATE1 cell monolayers. Compared with the metformin treatment-alone group, co-administration of nuciferine (40 mg/kg) markedly reduced the metformin concentration in mouse livers at 30 and 60 min after a single oral dose of metformin (200 mg/kg), and subsequently impaired the glucose-lowering effect of metformin (200 mg/kg), but the glucose-lowering effect became no different at 90 and 120 min. Therefore, nuciferine influenced the liver concentration and glucose-lowering effect of metformin only for a period of time after dose, administration of nuciferine and metformin with an interval might prevent the drug-drug interaction mediated by OCT1 and MATE1. PMID- 30294928 TI - Using photo-elicitation to explore the lived experience of informal caregivers of individuals living with dementia. AB - OBJECTIVES: This study aims to explore the subjective lived experience of informal caregivers supporting an individual with dementia. DESIGN: This study uses the interpretive phenomenological approach utilizing the method of photo elicitation and in-depth semi-structured interviews. METHODS: Six individuals were given a disposable camera to capture photographs which they felt illustrated their own lived experiences of being a caregiver of an individual living with dementia. Photographs were printed and used to form discussion within an in-depth semi-structured interview. The photographs provided an innovative way of capturing the lived experiences of formal dementia caregivers and allowed the interview data to be grounded in their daily living, centring around their own lived experiences. RESULTS: Three themes emerged from data analysis: 'conceptualising the role of informal caregiver', 'support for the informal caregiver', and 'the caregivers own needs'. CONCLUSIONS: Findings demonstrated the complexity of the relationship between the caregiver and the person living with dementia, and the shift in this relationship specifically due to the role of carer, with notable differences between spousal caregivers and adult-child caregivers. The importance of social, emotional, and practical support for caregivers was highlighted, as well as significance of the caregiver's individual needs. Statement of contribution What is already known on this subject? Informal caregivers of individuals living with dementia cover much of the associated health care costs. Informal caregiving of individuals living with dementia can lead to negative health outcomes of the carer. Health outcomes of informal caregivers living with dementia are grounded in culture and are influenced by multiple factors. What does this study add? The complexity of the transition from family member to informal caregiver has both a physical and emotional impact on caregivers. The transition, and experiences of informal caregiving, is dependent on the relationship to the individual living with dementia. Caregiver support and recognizing the caregiver's individual needs were imperative to caregiver well being. PMID- 30294929 TI - Bone Marrow Stem Cells-Seeded Polyethylene Terephthalate Scaffold in Repair and Regeneration of Rabbit Achilles Tendon. AB - The objective of this study was to evaluate the effect of bone marrow stem cells (BMSCs)-seeded polyethylene terephthalate (PET) scaffold for Achilles tendon repair in a rabbit model. The allogeneic BMSCs were seeded onto the PET scaffold and cultured in vitro for 14 days. Sixteen mature New Zealand rabbits underwent surgery to establish a 2-cm Achilles tendon defect model. The BMSCs-seeded PET scaffold was implanted into the defect of one limb (BMSCs-PET group), while the PET scaffold without BMSCs was implanted into the defect of contralateral limb as the control (PET group). All rabbits were sacrificed at 6 and 12 weeks after surgery. At 12 weeks after surgery, macroscopic and histological results showed formation of tendon-like tissues, and the structure was more mature in the BMSCs PET group. Immunohistochemical analysis and real-time polymerase chain reaction (RT-PCR) demonstrated that the collagen I and collagen III were significantly higher in the BMSCs-PET group compared with those in the PET group. Mechanically, both the failure load and the average stiffness were significantly higher in the BMSCs-PET group than those in the PET group. In conclusion, BMSCs-seeded PET scaffold could effectively facilitate the healing process after being implanted in a rabbit Achilles tendon defect model. PMID- 30294930 TI - Admission 25-Hydroxyvitamin D Levels Are Associated With Functional Status at Time of Discharge from Intensive Care Unit in Critically Ill Surgical Patients. AB - BACKGROUND: Vitamin D status is associated with length of stay (LOS) and discharge destination in critically ill patients. To further understand this relationship, we investigated whether admission 25-hydroxyvitaminD (25OHD) levels are associated with discharge functional status in the intensive care unit (ICU). METHODS: In this retrospective study, data from 2 surgical ICUs at a large teaching hospital were analyzed. 25OHD levels were measured within 24 hours of ICU admission and Functional Status Score for the ICU (FSS-ICU) was calculated within 24 hours of ICU discharge for all patients. To investigate the association of vitamin D status with FSS-ICU, we constructed linear and logistic regression models, controlling for body mass index, Nutrition Risk in the Critically Ill score, ICU LOS, and cumulative protein or caloric deficit during ICU admission. RESULTS: Mean 25OHD level and FSS-ICU was 19 (SD 8) ng/mL and 17 (SD 4), respectively, in the analytic cohort (n = 300). Each unit increase in 25OHD level was associated with a 0.2 increment in FSS-ICU (beta = .20; 95% CI 0.14-0.25). Patients with 25OHD levels <20 ng/mL had >3-fold risk of low FSS-ICU (<17) compared with patients with 25OHD >20 ng/mL (OR 3.45; 95% CI 1.96-6.08). CONCLUSIONS: Our results suggest that vitamin D status at admission is associated with discharge FSS-ICU in critically ill surgical patients. Future studies are needed to validate our results, to build upon our findings, and to determine whether optimizing 25OHD levels can improve functional status and other important clinical outcomes in ICU patients.

PMID- 30294932 TI - Modeling the Structure and Dynamics of Semantic Processing. AB - The contents and structure of semantic memory have been the focus of much recent research, with major advances in the development of distributional models, which use word co-occurrence information as a window into the semantics of language. In parallel, connectionist modeling has extended our knowledge of the processes engaged in semantic activation. However, these two lines of investigation have rarely been brought together. Here, we describe a processing model based on distributional semantics in which activation spreads throughout a semantic network, as dictated by the patterns of semantic similarity between words. We show that the activation profile of the network, measured at various time points, can successfully account for response times in lexical and semantic decision tasks, as well as for subjective concreteness and imageability ratings. We also show that the dynamics of the network is predictive of performance in relational semantic tasks, such as similarity/relatedness rating. Our results indicate that bringing together distributional semantic networks and spreading of activation provides a good fit to both automatic lexical processing (as indexed by lexical and semantic decisions) as well as more deliberate processing (as indexed by ratings), above and beyond what has been reported for previous models that take into account only similarity resulting from network structure.

AB - Biostatisticians play an important role in medical research. They are co responsible for an appropriate and efficient study design, they are involved in monitoring the study conduct, they plan and perform the data analysis, and they are involved in interpreting and publishing the results. However, how are the biostatisticians prepared for their tasks and responsibilities? Graduate programs in biostatistics are being offered, but some practicing biostatisticians completed their studies in a mathematical or epidemiological program, or obtained their degree in subject-specific fields (such as medicine or biology). Therefore, the expertise and the competencies can vary widely between the individual biostatisticians, also depending on the application field. In this article, focusing on European and US practices, we discuss the required professional expertise for the main areas of applications in the medical field as well as the necessary soft skill competencies of a biostatistician.

PMID- 30294937 TI - Resilience and mental health nursing: An integrative review of international literature. AB - Mental health nurses work in challenging and potentially high stress settings. Stressors can occur in the context of consumer, family, and/or staff relationships, as well as the work environment and organization. The cumulative effects of stress and professional challenges can lead to harmful impacts for mental health nurses including burnout and poorer physical and mental health. Resilience involves a process of positive adaptation to stress and adversity. The aims of this integrative review were to examine understandings and perspectives on resilience, and explore and synthesize the state of knowledge on resilience in mental health nursing. Following systematic search processes, screening, and data extraction, 12 articles were included. Constant comparative analysis and synthesis of the data resulted in two key categories: Theoretical concepts of resilience and Knowledge on mental health nurses' resilience. In mental health nursing, resilience has been variously constructed as an individual ability, collective capacity, or as an interactive person-environment process. Resilience was most often reported as low-moderate, with positive correlations with hardiness, self-esteem, life and job satisfaction, and negative correlations with depression and burnout. A resilience programme improved mental health nurses' coping self-efficacy and capacity to regulate thoughts and emotions and developed their resilient practice. Use of contemporary resilience definitions will inform more consistent investigation and progressively scaffold knowledge of this emergent construct in mental health nursing. Future research on the implementation of resilience programmes and resilience-building strategies for mental health nurses at the individual, work unit, and organizational levels is needed. PMID- 30294938 TI - A systematic review and meta-analysis of nutrition interventions for chronic noncancer pain. AB - BACKGROUND: This systematic review aimed to evaluate the impact of nutrition interventions on participant reported pain severity and intensity in populations with chronic pain. METHODS: Eight databases were systematically searched for studies that included adult populations with a chronic pain condition, a nutrition intervention and a measure of pain. Where possible, data were pooled using meta-analysis. Seventy-one studies were included, with 23 being eligible for meta-analysis. RESULTS: Studies were categorised into four groups: (i) altered overall diet with 12 of 16 studies finding a significant reduction in participant reported pain; (ii) altered specific nutrients with two of five studies reporting a significant reduction in participant reported pain; (iii) supplement-based interventions with 11 of 46 studies showing a significant reduction in pain; and (iv) fasting therapy with one of four studies reporting a significant reduction in pain. The meta-analysis found that, overall, nutrition interventions had a significant effect on pain reduction with studies testing an altered overall diet or just one nutrient having the greatest effect. CONCLUSIONS: This review highlights the importance and effectiveness of nutrition interventions for people who experience chronic pain. PMID- 30294939 TI - Obesity and loneliness. Findings from a longitudinal population-based study in the second half of life in Germany. AB - AIM: Little is known about whether changes to obesity are associated with changes in loneliness scores. Therefore, using a longitudinal approach, we aimed to determine whether the onset of obesity (explanatory variable) is associated with changes in loneliness (outcome measure) among older adults. METHODS: For the present study, data from wave 2 (2002) to wave 5 (2014) of the German Ageing Survey were analyzed. This is a representative sample of community-dwelling individuals in Germany (>=40 years). A validated six-item scale by Gierveld and van Tilburg was used to quantify loneliness. Obesity was defined as body mass index >=30 kg/m2 . Fixed effects regressions were used. RESULTS: Fixed effects regressions showed that loneliness increased with the onset of obesity among men but not among women. The sex * obesity interaction term was significant (P = 0.02). CONCLUSIONS: Findings stress the importance of the onset of obesity for loneliness among older men. Weight management strategies might also be a promising strategy to reduce loneliness scores. PMID- 30294941 TI - How we approach: Severe congenital neutropenia and myelofibrosis due to mutations in VPS45. AB - Mutations in the VPS45 gene lead to a severe primary immune deficiency characterized by severe congenital neutropenia and primary myelofibrosis, leading to overwhelming infection and early death. This condition is exceedingly rare with only 16 patients previously reported, including four with successful hematopoietic stem cell transplantation. We review the pathophysiology underlying this condition and detail our approach to treatment, particularly vis-a-vis bone marrow transplantation and the challenges of transplanting into a diseased bone marrow niche. We provide an update on the progress of our three previously reported patients, and two additional patients transplanted at our center. PMID- 30294940 TI - Spontaneous primary hypothyroidism in 7 adult cats. AB - BACKGROUND: Naturally occurring hypothyroidism in adult cats is rare, with only 4 cases reported. OBJECTIVES: To describe the historical, clinical, laboratory, and scintigraphic features of adult cats with spontaneous hypothyroidism. ANIMALS: Seven adult cats referred for suspected hypothyroidism. METHODS: Prospective case series. We collected data on cats' signalment, clinical signs, results of physical examination, routine laboratory and thyroid hormone testing, and thyroid imaging (thyroid scintigraphy or ultrasound). We subsequently treated cats with levothyroxine and evaluated their response to treatment. RESULTS: Cats ranged from 3.5 to 11 years, with no apparent breed predilection; 6/7 cats were male. Only 2/7 cats were initially tested because of signs of hypothyroidism (hair-coat changes, lethargy, obesity); others were tested for routine thyroid monitoring or palpable thyroid nodules. Four were azotemic (serum creatinine, 2.2-3.4 mg/dL). Six of the cats had low serum thyroxine (T4 ) and free T4 (fT4 ) concentrations, whereas all 7 cats had high thyroid-stimulating hormone (TSH) concentrations. In 6/7 cats, thyroid scintigraphy revealed bilateral goiter with intense radionuclide uptake; imaging showed no visible thyroid tissue in the other. After levothyroxine treatment, serum concentrations of T4 and fT4 increased and TSH fell; high serum creatinine normalized in azotemic cats; and repeat imaging showed reduction in goiter size. CONCLUSIONS AND CLINICAL IMPORTANCE: Primary hypothyroidism develops in adult cats, with a higher prevalence than previously thought. Most cats appear to develop a goitrous form of hypothyroidism associated with thyroid hyperplasia, whereas thyroid atrophy appears to be less common. With levothyroxine replacement, clinical and laboratory abnormalities improve or resolve. PMID- 30294942 TI - Comprehensive analysis of aberrantly expressed profiles of messenger RNA in alcoholic liver disease. AB - BACKGROUND: Alcoholic liver disease (ALD) is one of the major cause of morbidity and mortality of clinical liver disease worldwide. Until today, although many general therapies are carried out and several molecular targets have been proposed to act as the potential therapeutic targets, more accurate molecular targets and more effective therapeutic methods remain needed. MATERIAL AND METHODS: In the study, we analyze the differential expression genes (DEGs) between the patients with ALD and healthy controls. Gene Ontology enrichment and KEGG signaling pathway analysis are performed to identify the function of DEGs. Some significant molecules are proposed to act as the potential therapeutic targets for ALD. RNA data of 15 ALD tissues and 7 normal tissues for RNA expression analysis were obtained. DEGs in ALD samples compared with normal tissues identified through the limma R package and subjected to network analysis. RESULTS: As a result, we obtained a total of 274 DEGs that mainly involved in biological processes related to the angiogenesis, stress reaction, synthesis, and metabolism of organic acids. Network analysis obtained several genes with high network degree and fold change. Some significant molecules are proposed to act as the potential therapeutic targets for ALD. CONCLUSIONS: Our research identified some new progression-related genes of alcohol liver diseases, which could be regarded as the new targets for the early diagnosis and therapeutic management in ALD. PMID- 30294943 TI - Hepatic copper concentrations in 546 dogs (1982-2015). AB - BACKGROUND: Copper associated hepatitis (CAH) has been increasingly recognized in dogs, and speculation exists that hereditary defects in copper metabolism have been exacerbated by increased environmental copper exposure. However, no broad epidemiological investigations have been performed to investigate quantitative hepatic copper concentrations ([Cu]H ) over time in both dogs that are (predisposed breed [PB]), and are not (non-predisposed breed [NPB]), considered at-risk for CAH. OBJECTIVES: To investigate [Cu]H in dogs and explore temporal, demographic, and histologic associations spanning 34 years. ANIMALS: 546 archived liver specimens. METHODS: Retrospective study. Searches of the Michigan State University Veterinary Diagnostic Laboratory database identified dogs that had undergone hepatic histopathologic assessment. Cases with archived tissue were reviewed and classified by breed, time period, and presence or absence of hepatitis. Inductively coupled plasma mass spectrometry was used to determine [Cu]H . RESULTS: In time period 2009-2015, median [Cu]H were 101 MUg/g and 313 MUg/g greater than median [Cu]H in time period 1982-1988 for NPB and PB dogs, respectively (P < .001 for both comparisons). The proportion of dogs with [CU]H > 300 MUg/g increased in NPB (28% to 49%) and PB dogs (48% to 71%) during these periods (P = .002 for both comparisons). Median [Cu]H in dogs with hepatitis increased 3-fold over time in both NPB (P = .004) and PB populations (P < .001). CONCLUSIONS AND CLINICAL IMPORTANCE: The frequent recognition of CAH in recent years is likely due to the observed increases in [Cu]H over time. Importantly, effects are not limited to PB dogs. PMID- 30294944 TI - Identification and frequency of the associated genes with virulence and antibiotic resistance of Escherichia coli isolated from cow's milk presenting mastitis pathology. AB - Antimicrobial resistance, genotype, and virulence gene content of Escherichia coli isolated from bovine clinical mastitis in Tehran Province, Iran, were studied. Two hundred seven (207) milk samples from individual cows presenting mastitis symptoms collected from different dairy farms were used to determine the presence of specific genes of E. coli responsible for this pathology. Multiplex PCR was used to differentiate E. coli isolates into different phylogenetic groups/subgroups and to detect their virulence and involved resistance genes. All the isolated strains were tested for the susceptibility to 21 antimicrobial agents. The results showed that E. coli was detected in 42 (20.3%) samples and 69% of them belonged to the phylogenetic groups A and B1. The phylogenetic subgroup A1 (31%) and subgroup B1 (28.6%) demonstrated the highest prevalence of virulence genes (f17c-A, and eae (n = 6), f17b-A, and f17d-A (n = 5), afaD-8, afaE-8, aucD, and bfpA (n = 4), clpG and VT (n = 2), and LT and ST genes (n = 1)). The highest antimicrobial resistance was observed for tetracycline (45.2%) followed by streptomycin (26.2%). The antimicrobial resistance genes tetB (31%), tetA (28.6%), and aadA (26.2%) were the most prevalent. Moreover, integron class 1 and 2 were found in 24 (57.1%) and 8 (19%) of the E. coli isolates. PMID- 30294945 TI - PARENTS 2 Study: consensus report for parental engagement in the perinatal mortality review process. AB - OBJECTIVES: Following a perinatal death, a standardised multidisciplinary review should take place. Learning from these deaths and engaging parents in this process could help prevent future perinatal deaths in line with United Kingdom (UK) national and international targets to reduce the number of such deaths by 2020. Moreover, it would support parents in understanding events around the death of their baby. An earlier study (Parents' Active Role and ENgagement in The review of their Stillbirth/perinatal death - PARENTS 1 study) found that parents would endorse the opportunity to give feedback into the perinatal mortality review process (PNMR). In subsequent focus groups, healthcare professionals were positive about parental engagement, although they considered there may be significant challenges. The objective of this study was to develop core principles and recommendations for parental engagement in PNMR in the UK. METHODS: We followed a two-round Delphi technique to reach a consensus on core principles; including a national consensus workshop and an online questionnaire. The consensus meeting was attended by a national panel of stakeholders (clinical and academic experts, parent support groups, managers and commissioners) in stillbirth, neonatal and bereavement care (n=22). To develop recommendations for parental engagement, participants discussed four key areas including: receiving feedback from parents; format of the PNMR meeting; the parental pathway; and challenging aspects of engaging with parents in reviews. Content analysis was conducted to generate recommendations from the meeting for a subsequent, anonymous web-based survey. Attendees of the consensus workshop and members of the PARENTS 2 Project Advisory Board were asked to rank recommendations using a 9 point Likert scale from 1 (not important) to 9 (critical). It had been agreed a priori, in compliance with established Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria, that 'Consensus' would be achieved if over 70% scored the principle as 'critical' (score 7 to 9) and less than 15% scored the principle as 'not important' (score 1 to 3). Principles where Consensus was achieved would be included in the core recommendations. RESULTS: Twenty-five of the 29 invited stakeholders participated in the consensus meeting and the subsequent online questionnaire in June 2017 (86.2% response rate). Consensus was agreed on 12 core principles. Ninety-six percent agreed that it was of critical importance that there should be a face-to-face explanation of the PNMR process; 72% considered parents should be offered the opportunity to nominate a suitable advocate; 92% believed responses to parents' comments should be formally documented; 96% indicated that it was vital for action plans to be translated into lessons learnt and that this process is monitored; and 100% of stakeholders voted that a plain English summary should be produced for the parents following the meeting. There was good agreement on a further seven principles. CONCLUSIONS: Key national stakeholders were unanimously supportive of parental engagement and agreed on core principles to make it feasible, meaningful and robust process. A six-month pilot of parental engagement in the perinatal mortality review process (PARENTS 2 Study) in two UK units took place after the consensus on core principles. In collaboration with the National Perinatal Epidemiology Unit, findings will inform the national standardised perinatal mortality review tool (PMRT). This article is protected by copyright.

AB - Atypical hemolytic uremic syndrome (aHUS), a rare variant of thrombotic microangiopathy, is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and renal impairment. The condition is associated with poor clinical outcomes with high morbidity and mortality. Atypical HUS predominantly affects the kidneys but has the potential to cause multi-organ system dysfunction. This uncommon disorder is caused by a genetic abnormality in the complement alternative pathway resulting in over-activation of the complement system and formation of microvascular thrombi. Abnormalities of the complement pathway may be in the form of mutations in key complement genes or autoantibodies against specific complement factors. We discuss the pathophysiology, clinical manifestations, diagnosis, complications, and management of aHUS. We also review the efficacy and safety of the novel therapeutic agent, eculizumab, in aHUS, pregnancy-associated aHUS, and aHUS in renal transplant patients. PMID- 30294947 TI - Piezoelectric Biomaterials for Sensors and Actuators. AB - Recent advances in materials, manufacturing, biotechnology, and microelectromechanical systems (MEMS) have fostered many exciting biosensors and bioactuators that are based on biocompatible piezoelectric materials. These biodevices can be safely integrated with biological systems for applications such as sensing biological forces, stimulating tissue growth and healing, as well as diagnosing medical problems. Herein, the principles, applications, future opportunities, and challenges of piezoelectric biomaterials for medical uses are reviewed thoroughly. Modern piezoelectric biosensors/bioactuators are developed with new materials and advanced methods in microfabrication/encapsulation to avoid the toxicity of conventional lead-based piezoelectric materials. Intriguingly, some piezoelectric materials are biodegradable in nature, which eliminates the need for invasive implant extraction. Together, these advancements in the field of piezoelectric materials and microsystems can spark a new age in the field of medicine. PMID- 30294948 TI - Phosphine-Catalyzed Difunctionalization of beta-Fluoroalkyl alpha,beta-Enones: A Direct Approach to beta-Amino alpha-Diazo Carbonyl Compounds. AB - An efficient and practical phosphine-catalyzed vicinal difunctionalization of beta-fluoroalkyl alpha,beta-enones with TMSN3 has been developed. Using dppb as the catalyst, the reaction worked efficiently to yield various beta-amino alpha diazocarbonyl compounds in high yields (up to 94 %). This work marks the first efficient construction of alpha-diazocarbonyl compounds by phosphine catalysis. Meanwhile, the asymmetric variant induced by the nucleophilic bifunctional phosphine P4 led to various chiral fluoroalkylated beta-amino alpha-diazocarbonyl compounds in high yields and enantioselectivity. NMR and ESI-MS studies support the existence of the key reaction intermediates. In contrast, beta-azide carbonyl compounds would be furnished in good yields from beta-fluoroalkylated beta,beta disubstituted enones. PMID- 30294949 TI - Developmental gene expression patterns in the brain and liver of Xenopus tropicalis during metamorphosis climax. AB - Thyroid hormones (THs) induce metamorphosis in amphibians, causing dynamic changes, whereas mammalian newborns undergo environmental transition from placenta to open air at birth. The similarity between amphibian metamorphosis and the mammalian perinatal periods has been repeatedly discussed. However, a corresponding developmental gene expression analysis has not yet been reported. In this study, we examined the developmental gene expression profiles in the brain and liver of Xenopus tropicalis during metamorphosis climax and compared them to the respective gene expression profiles of newborn rodents. Many upregulated genes identified in the tadpole brain during metamorphosis are also upregulated in the rodent brain during the first three postnatal weeks when the TH surge occurs. The upregulation of some genes in the brain was inhibited in thyroid hormone receptor alpha (TRalpha) knockout tadpoles but not in TRbeta knockout tadpoles, implying that brain metamorphosis is mainly mediated by TRalpha. The expression of some genes was also increased in the liver during metamorphosis climax. Our data suggest that the rodent brain undergoes TH dependent remodeling during the first three postnatal weeks as observed in X. tropicalis during the larva-to-adult metamorphosis. PMID- 30294950 TI - Blood Concentrations of Complement Split Product iC3b and Serum C3 Associate with SLE Disease Activity. AB - OBJECTIVE: To examine correlations between blood levels of complement split product iC3b and serum component C3 with clinically meaningful changes in disease activity in patients with systemic lupus erythematosus (SLE). METHODS: 159 consecutive subjects with American College of Rheumatology or Systemic Lupus International Collaborating Clinics classified SLE were enrolled into CASTLE (Complement Activation Signatures in Systemic Lupus Erythematosus), a prospective observational study. Patients with 1-7 study visits were included in this longitudinal analysis. 48 healthy volunteers were enrolled to establish the normal reference iC3b/C3 ratio. Serum C3 and C4 were measured by nephelometry and blood iC3b levels by a lateral flow assay. SLE disease activity was monitored utilizing the Systemic Lupus Erythematosus Disease Activity Index 2K Responder Index-50 instrument. RESULTS: iC3b/C3 ratio, double-stranded (ds)DNA antibodies (Abs), and supraphysiologic prednisone dose (>7.5 mg/day) each independently correlated with SLE disease activity, employing multilevel multiple logistic regression analysis. Only the iC3b/C3 ratio was significantly associated with clinically meaningful improvements in disease activity among subjects receiving supraphysiologic doses of prednisone. iC3b/C3 outperformed C3 and C4 levels discriminating both active versus inactive SLE disease and major flares versus no disease activity. iC3/C3, dsDNA Abs, ESR, and supraphysiologic prednisone dose were independently associated with lupus nephritis, while none were associated with SLE rash. The association of iC3b/C3 with nephritis was independent of other observed clinical manifestations. CONCLUSION: Blood iC3b/C3 correlates with SLE disease activity and clinically meaningful changes. Furthermore, it discriminates between active versus inactive SLE, and major flares compared to those patients without active disease. This article is protected by copyright. All rights reserved. PMID- 30294951 TI - Socially isolated older people with mental illness in Tokyo homeless shelters. PMID- 30294952 TI - Treating diabetic complications; from large randomized clinical trials to precision medicine. AB - In the last decades, many large randomized controlled trials have been conducted to assess the efficacy and safety of new interventions for the treatment of diabetic kidney disease (DKD). Unfortunately, these trials failed to demonstrate additional kidney or cardiovascular protection. One of the explanations for the failure of these trials appears to be the large variation in drug response between individual patients. All trials to date tested a drug which was targeted to a large heterogeneous population assuming that every individual will show a similar beneficial respond to the drug. Post hoc analyses from the past clinical trials, however, suggest that individual patients show a marked variation in drug response. This highlights the need to personalize treatment taking proper account of the characteristics and preferences of individual patients. Transitioning to a personalized therapy approach will have implications for clinical trial designs, drug registration and its use in clinical practice. Successful implementation of personalized medicine thus requires engagement of multiple stakeholders including academic community, pharmaceutical industry, regulatory agencies, health policy makers, physicians and patients. This supplement of Diabetes Obesity and Metabolism provides a summary on the state-of-the-art of personalized medicine in diabetic kidney disease from the views of various stakeholders. PMID- 30294953 TI - Precision medicine in diabetes and diabetic kidney disease: Regulatory considerations. AB - Over the past 15 years, three new classes of drugs, glucagon-like peptide-1 (GLP 1) receptor agonists, dipeptidyl peptidase 4 (DPP-4) inhibitors and sodium glucose cotransporter-2 (SGLT-2) inhibitors have been approved to treat type 2 diabetes based on effects on glycemic control. Although large randomized controlled trials have played an important role in characterizing the efficacy and safety of these agents on a population level, questions remain about how best to individualize therapy and target the "right" medicine to the "right" patient. In contrast, few medicines have been approved to treat diabetic kidney disease and initiatives have been launched on both sides of the Atlantic to facilitate the development of effective personalized medicines for the treatment of diabetic kidney disease. Increasingly, "omics," imaging and other biomarkers will be used to match patients with therapies to which they are likely to respond best. This review addresses regulatory considerations related to precision medicine, draws lessons learned from other therapeutic areas and discusses efforts undertaken by the European (EMA) and United States (FDA) to facilitate the development of such therapies. Moving forward, an integrated approach that makes use of predictive preclinical models, innovative trial designs, observational "real-world" data and novel statistical methodologies will likely be needed to complement inherently smaller RCTs conducted in more selected populations. Patient involvement will also be critical. Regulatory agencies are ready to engage in such approaches. PMID- 30294954 TI - New clinical trial designs for establishing drug efficacy and safety in a precision medicine era. AB - Despite advances in pharmacotherapy, diabetic kidney disease (DKD) remains associated with a high burden of micro- and macrovascular complications often leading to premature mortality. New therapies are highly desirable to mitigate the burden of this disease. However, there are a number of barriers that hamper drug development in DKD. These include, amongst others, the lengthy and complex clinical trials required to prove drug efficacy and safety, inefficiencies in clinical trial conduct, and the high costs associated with these development programs. In this review a number of aspects are discussed, aiming to identify opportunities to transform and innovate drug development for DKD. Many clinical trials in DKD, as well as in other areas, face difficulties in timely and efficient enrolment of participants. To address this issue a network of sites should be created that are continuously recruiting individuals with DKD and collecting crucial information that can be used to understand prognosis and prognostic factors, and more importantly to serve as a pool of participants for recruitment to randomized trials. Second, the current clinical endpoints are late events in the progression of DKD. Endpoints based on lesser declines in estimated glomerular filtration rate (eGFR) or changes in albuminuria can shorten follow-up and/or lead to smaller and cheaper trials. Enrichment by enrolling clinical trial populations based on biomarker profiles is another approach that may facilitate clinical trial efficiency and conduct. Biomarkers can be used to individualize treatment by targeting populations more likely to respond leading to smaller and more efficient trials. Finally, using new trial design such as basket, umbrella or more broadly platform trials to assess a number of therapies simultaneously offers the potential to transform the drug development process in DKD. There are a number of opportunities to transform development approaches for new therapies for DKD. Platform trials along with appropriate biomarker-based enrichment strategies offer the possibility to foster drug development in a precision medicine era. PMID- 30294955 TI - Implementing personalized medicine in diabetic kidney disease: Stakeholders' perspectives. AB - The promise of personalized medicine to deliver "the right treatments at the right time to the right person" is the next frontier in healthcare. However, to implement personalized medicine in chronic diseases such as diabetes mellitus and diabetic kidney disease (DKD), a number of different aspects need to be taken into account. Better risk stratification and more precise options for treatment need to be developed and included in clinical practice guidelines. A patient's unique psychological, social and environmental situation also drive disease progression and outcomes. Appraising the cost effectiveness of precision medicines is necessary, not just as the cost of new therapies, but also the cost of diagnosis with novel methodologies and averted complications. As the prevalence of DKD grows worldwide to epidemic proportions, challenges such as global disparities in resources, access to healthcare and prevalence need to be addressed. This review considers these issues to achieve the short and longer term goals of implementing personalized medicine in clinical practice. PMID- 30294956 TI - An integrative systems biology approach for precision medicine in diabetic kidney disease. AB - Current therapeutic approaches are ineffective in many patients with established diabetic kidney disease (DKD), an epidemic affecting one in three patients with diabetes. Early identification of patients at high risk for progression and individualizing therapies have the potential to mitigate kidney complications due to diabetes. To achieve this, a better understanding of the complex pathophysiology of DKD is needed. A system biology approach integrating large scale omic data is well suited to unravel the molecular mechanisms driving DKD and may offer new perspectives how to personalize therapy. Recent studies indeed show that integrating genome scale data sets generated from prospectively designed clinical cohort studies with model systems using innovative bioinformatics analysis revealed critical molecular pathways in DKD and led to the development of candidate prognostic molecular biomarkers. This review seeks to provide an overview of the recent progress in the application of the integrative systems biology approaches specifically in the field of molecular biomarkers for DKD. We will mainly focus the discussion on how to use integrative system biology approach to first identify patients at high risk of progression, and second to identify patients who may or may not respond to treatment. Challenges and opportunities in applying precision medicine in DKD will also be discussed. PMID- 30294957 TI - Enhancement of transgene expression by nuclear transcription factor Y and CCCTC binding factor. AB - If a transgene is effectively delivered to a cell, its expression may still be limited by epigenetic mechanisms that silence the transgene. Indeed, once the transgene reaches the nucleus, it may be bound by histone proteins and condensed into heterochromatin or associated with repressor proteins that block transcription. In this study, we sought to enhance transgene expression by adding binding motifs for several different epigenetic enzymes either upstream or downstream of two promoters (CMV and EF1alpha). Screening these plasmids revealed that luciferase expression was enhanced 10-fold (10.4 +/- 5.8) by the addition of a CCAAT box just upstream of the EF1alpha promoter to recruit nuclear transcription factor Y (NF-Y), while inserting a CCCTC-binding factor (CTCF) motif downstream of the EF1alpha promoter enhanced expression at least 14-fold (14.03 +/- 6.54). ChIP assays confirmed that NF-Y and CTCF bound to the motifs that were added to each plasmid, but the presence of NF-Y and CTCF did not significantly affect the levels of histone acetylation (H3K9ac) or methylation (H3K9me3). Overall, these results show that transgene expression from the EF1alpha promoter can be significantly increased with motifs that recruit NF-Y or CTCF.

AB - The objective was to use various somatic parameters as basis for investigating the physical health of older adults with severe mental illnesses (SMI). A cross sectional study design is performed by using baseline data from the Physical Health in SMI-elderly (PHiSMI-E) study. Data were collected using the Nursing Monitoring of Somatic Status and Lifestyle - Mental Health instrument in adults aged over 60 with SMI in a large Dutch mental health institute. Ninety-nine elderly SMI patients were included. Somatic comorbidity (84.8%), use of somatic medication (77.7%) and polypharmacy (67.7%) were prevalent. Extrapyramidal symptoms were experienced by 51% of patients, mainly in the subgroup with psychotic disorders (75.6%). Unhealthy diet was reported in 16.2%, obesity in 27.3%, and physical inactivity in 57.6%. Fatigue (67.7%) and dry mouth (66.6%) were the commonest reported physical symptoms. Mean VAS score (scale 0-10) indicating participants' self-perceived physical health was 6.7 (SD +/- 1.6). After division of the total patient group into tertiles based on the VAS scores, the lowest tertile was characterized by less physical activity, unhealthier diet, more use of medication, more fatigue, somnolence, and inner agitation. In conclusion, impaired physical health status was common in these older patients with SMI. Although they had more psychiatric and somatic comorbidity than adult SMI patients described in the literature, they had a healthier lifestyle. To reduce morbidity and premature mortality in these frail patients, it is essential that healthcare providers are aware of the high prevalence of somatic comorbidity and symptoms, and of their interactions with the psychiatric disorders. This study improves our understanding of differences in vulnerability factors of older patients with SMI. The (early) detection of somatic comorbidities may improve long-term health outcomes of these patients. PMID- 30294959 TI - Arterial damage and cognitive impairment in patients with chronic kidney disease. PMID- 30294961 TI - Innate lymphoid cells, mediators of tissue homeostasis, adaptation and disease tolerance. AB - Innate lymphoid cells (ILC) are a recently identified group of tissue-resident innate lymphocytes. Available data support the view that ILC or their progenitors are deposited and retained in tissues early during ontogeny. Thereby, ILC become an integral cellular component of tissues and organs. Here, we will review the intriguing relationships between ILC and basic developmental and homeostatic processes within tissues. Studying ILC has already led to the appreciation of the integral roles of immune cells in tissue homeostasis, morphogenesis, metabolism, regeneration, and growth. This area of immunology has not yet been studied in depth but is likely to reveal important networks contributing to disease tolerance and may be harnessed for future therapeutic approaches. PMID- 30294962 TI - Type 2 innate lymphoid cells in the induction and resolution of tissue inflammation. AB - Type 2 immunity against pathogens is tightly regulated to ensure appropriate inflammatory responses that clear infection and prevent excessive tissue damage. Recent research has shown that type 2 innate lymphoid cells (ILC2s) contribute to steady-state tissue integrity and exert tissue-specific functions. However, upon exposure to inflammatory stimuli, they also initiate and amplify type 2 inflammation by inducing mucus production, eosinophilia, and Th2 differentiation. In this review, we discuss the regulation of ILC2 activation by transcription factors and metabolic pathways, as well as by extrinsic signals such as cytokines, lipid mediators, hormones, and neuropeptides. We also review recent discoveries about ILC2 plasticity and heterogeneity in different tissues, as revealed partly through single-cell RNA sequencing of transcriptional responses to various stimuli. Understanding the tissue-specific pathways that regulate ILC2 diversity and function is a critical step in the development of potential therapies for allergic diseases. PMID- 30294963 TI - The group 2 innate lymphoid cell (ILC2) regulatory network and its underlying mechanisms. AB - Group 2 innate lymphoid cells (ILC2s) play critical roles in the induction of type 2 inflammation, response to parasite infection, metabolic homeostasis, and tissue repair. These multifunctional roles of ILC2s are tightly controlled by complex regulatory systems in the local microenvironment, the disruption of which may cause various health problems. This review summarizes up-to-date knowledge regarding positive and negative regulators for ILC2s based on their function and signaling pathways, including activating cytokines (IL-33, IL-25; MAPK, NF-kappaB pathways), co-stimulatory cytokines (IL-2, IL-7, IL-9, TSLP; STAT5, IL-4; STAT6, TNF superfamily; MAPK, NF-kappaB pathways), suppressive cytokines (type1 IFNs, IFN-gamma, IL-27; STAT1, IL-10, TGF-beta), transdifferentiation cytokines (IL-12; STAT4, IL-1beta, IL-18), lipid mediators (LTC4, LTD4, LTE4, PGD2; Ca2+ -NFAT pathways, PGE2, PGI2; AC/cAMP/PKA pathways, LXA4, LTB4), neuropeptides (NMU; Ca2+ -NFAT, MAPK pathways, VIP, CGRP, catecholamine, acetylcholine), sex hormones (androgen, estrogen), nutrients (butyrate; HDAC inhibitors, vitamins), and cell to-cell interactions (ICOSL-ICOS; STAT5, B7-H6-NKp30, E-cadherin-KLRG1). This comprehensive review affords a better understanding of the regulatory network system for ILC2s, providing impetus to develop new treatment strategies for ILC2 related health problems. PMID- 30294960 TI - Neuroendocrine regulation of innate lymphoid cells. AB - The activities of the immune system in repairing tissue injury and combating pathogens were long thought to be independent of the nervous system. However, a major regulatory role of immunomodulatory molecules released locally or systemically by the neuroendocrine system has recently emerged. A number of observations and discoveries support indeed the notion of the nervous system as an immunoregulatory system involved in immune responses. Innate lymphoid cells (ILCs), including natural killer (NK) cells and tissue-resident ILCs, form a family of effector cells present in organs and mucosal barriers. ILCs are involved in the maintenance of tissue integrity and homeostasis. They can also secrete effector cytokines rapidly, and this ability enables them to play early roles in the immune response. ILCs are activated by multiple pathways including epithelial and myeloid cell-derived cytokines. Their functions are also regulated by mediators produced by the nervous system. In particular, the peripheral nervous system, through neurotransmitters and neuropeptides, works in parallel with the hypothalamic-pituitary-adrenal and gonadal axis to modulate inflammatory events and maintain homeostasis. We summarize here recent findings concerning the regulation of ILC activities by neuroendocrine mediators in homeostatic and inflammatory conditions. PMID- 30294964 TI - Innate lymphoid cells in lung infection and immunity. AB - In recent years, innate lymphoid cells (ILCs) have emerged as key mediators of protection and repair of mucosal surfaces during infection. The lung, a dynamic mucosal tissue that is exposed to a plethora of microbes, is a playground for respiratory infection-causing pathogens which are not only a major cause of fatalities worldwide, but are also associated with comorbidities and decreased quality of life. The lung provides a rich microenvironment to study ILCs in the context of innate protection mechanisms within the airways, unraveling their distinct functions not only in health but also in disease. In this review, we discuss how pulmonary ILCs play a role in protection against viral, parasitic, bacterial, and fungal challenge, along with the mechanisms underlying this ILC mediated immunity. PMID- 30294966 TI - Deconstructing deployment of the innate immune lymphocyte army for barrier homeostasis and protection. AB - The study of the immune system has shifted from a purely dichotomous separation between the innate and adaptive arms to one that is now highly complex and reshaping our ideas of how steady-state health is assured. It is now clear that immune cells do not neatly fit into these two streams and immune homeostasis depends on continual dialogue between multiple lineages of the innate (including dendritic cells, innate lymphoid cells, and unconventional lymphocytes) and adaptive (T and B lymphocytes) arms together with a finely tuned synergy between the host and microbes which is essential to ensure immune homeostasis. Innate lymphoid cells are critical players in this new landscape. Here, we discuss recent studies that have elucidated in detail the development of ILCs from their earliest progenitors and examine factors that influence their identification and ability to drive immune homeostasis and long-term immune protection. PMID- 30294967 TI - Introduction: Basic and emerging concepts in ILC biology. PMID- 30294968 TI - Thinking differently about ILCs-Not just tissue resident and not just the same as CD4+ T-cell effectors. AB - Innate lymphoid cells (ILCs) resemble adaptive T lymphocytes based on transcription factor expression, cytokine production, and their presumptive roles in immunity, but are activated for effector function through cytokine signaling and not antigen-specific receptors. The prevailing view is that ILCs adapt to specific microenvironments during development and operate as tissue-resident cells in co-operation with antigen-specific T cells to provide host protection and contribute to tissue maintenance. In particular, conventional models equate the activity of different ILC subsets with CD4+ effector T-cell types based on corresponding transcription factor expression and a potential for comparable cytokine production. Based on recent data from our laboratory, we suggest that these views on tissue residence and parallel functioning to CD4+ T cells are too restrictive. Our findings show that ILC2s can be mobilized from the gut under inflammatory conditions and contribute to distal immunity in the lungs during infection, whereas gut-resident ILC3s operate in a quite distinct manner from Th17 CD4+ effector cells in responding to commensal microbes, with important implications for control of metabolic homeostasis. In this review, we discuss the recent advances leading to these revised views of ILC inter-organ trafficking and the distinct and complementary function of ILCs with respect to adaptive T cells in establishing and maintaining a physiologic host environment. PMID- 30294969 TI - New insights into the function, development, and plasticity of type 2 innate lymphoid cells. AB - Group 2 innate lymphoid cells (ILC2s) are the most well defined group of ILCs. ILC2 development is controlled by the GATA-3 transcription factor and these cells produce archetypal type 2 cytokines, such as IL-5 and IL-13. These cytokines mediate parasite expulsion and tissue repair, but also contribute to type 2 inflammatory diseases, including allergy, asthma and chronic rhinosinusitis with nasal polyps. In response to tightly regulated local environmental cues ILCs can generate characteristics of other subtypes, a process known as plasticity. Recent advances in the ILC2 field has led to the discovery that ILC2s can promptly shift to functional IFN-gamma-producing ILC1s or IL-17-producing ILC3s, depending on the cytokines and chemokines produced by antigen presenting cells or epithelial cells. Due to yet unknown triggers, this complex network of signals may become dysregulated. In this review, we will discuss general ILC characteristic, ILC2 development, plasticity, memory function, and implications in disease. PMID- 30294965 TI - JAK/STAT signaling in regulation of innate lymphoid cells: The gods before the guardians. AB - Immunity to pathogens is ensured through integration of early responses mediated by innate cells and late effector functions taking place after terminal differentiation of adaptive lymphocytes. In this context, innate lymphoid cells (ILCs) and adaptive T cells represent a clear example of how prototypical effector functions, including polarized expression of cytokines and/or cytotoxic activity, can occur with overlapping modalities but different timing. The ability of ILCs to provide early protection relies on their poised epigenetic state, which determines their propensity to quickly respond to cytokines and to activate specific patterns of signal-dependent transcription factors. Cytokines activating the Janus kinases (JAKs) and members of the signal transducer and activator of transcription (STAT) pathway are key regulators of lymphoid development and sustain the processes underlying T-cell activation and differentiation. The role of the JAK/STAT pathway has been recently extended to several aspects of ILC biology. Here, we discuss how JAK/STAT signals affect ILC development and effector functions in the context of immune responses, highlighting the molecular mechanisms involved in regulation of gene expression as well as the potential of targeting the JAK/STAT pathway in inflammatory pathologies. PMID- 30294972 TI - A 46,XX testicular disorder of sex development caused by a Wilms' tumour Factor-1 (WT1) pathogenic variant. AB - Molecular diagnosis is rarely established in 46,XX testicular (T) disorder of sex development (DSD) individuals with atypical genitalia. The Wilms' tumour factor-1 (WT1) gene is involved in early gonadal development in both sexes. Classically, WT1 deleterious variants are associated with 46,XY disorders of sex development (DSD) because of gonadal dysgenesis. We report a novel frameshift WT1 variant identified in an SRY-negative 46,XX testicular DSD girl born with atypical genitalia. Target massively parallel sequencing involving DSD-related genes identified a novel heterozygous WT1 c.1453_1456del; p.Arg485Glyfs*14 variant located in the fourth zinc finger of the protein which is absent in the population databases. Segregation analysis and microsatellite analysis confirmed the de novo status of the variant that is predicted to be deleterious by in silico tools and to increase WT1 target activation in crystallographic model. This novel and predicted activating frameshift WT1 variant leading to the 46,XX testicular DSD phenotype includes the fourth zinc-finger DNA-binding domain defects in the genetic aetiology of 46,XX DSD. PMID- 30294973 TI - A Density Functional Theoretical Study on the Charge-Transfer Enhancement in Surface-Enhanced Raman Scattering. AB - The chemical enhancement due to ground-state charge transfer (GSCT) and photon driven charge transfer (PDCT) in surface-enhanced Raman scattering (SERS) has been investigated by density functional theory. Para-substituted thiophenol derivatives adsorbed on silver and gold surfaces are selected as model systems to evaluate the chemical enhancement factor. By changing the functional groups on thiophenol, we are allowed to modulate the chemical interactions between the thiophenol and the metal cluster in both ground state and charge transfer excited state. Both off-resonance and pre-resonance SERS spectra are simulated to calculate the chemical enhancement factors. The GSCT enhancement factor, EFGSCT , shows a roughly linear relationship to (omegaTP /omegaM-TP )4 , where omegaTP denotes the HOMO-LUMO gap of free molecule, and omegaM-TP denotes the energy difference between the HOMO of the molecule and the LUMO of the metal. The PDCT enhancement factor, EFPDCT , is governed by the energy difference between the incident light energy and the excitation energy to the CT excited state. EFPDCT first increases and then decreases with the increase of incident light energy. PMID- 30294971 TI - Metabolic regulation of innate and adaptive lymphocyte effector responses. AB - Innate and adaptive lymphocytes employ diverse effector programs that provide optimal immunity to pathogens and orchestrate tissue homeostasis, or conversely can become dysregulated to drive progression of chronic inflammatory diseases. Emerging evidence suggests that CD4+ T helper cell subsets and their innate counterparts, the innate lymphoid cell family, accomplish these complex biological roles by selectively programming their cellular metabolism in order to instruct distinct modules of lymphocyte differentiation, proliferation, and cytokine production. Further, these metabolic pathways are significantly influenced by tissue microenvironments and disease states. Here, we summarize our current knowledge on how cell-intrinsic metabolic factors modulate the context dependent bioenergetic pathways that govern innate and adaptive lymphocytes. Further, we propose that a greater understanding of these pathways may lead to the identification of unique features in each population and provoke the development of novel therapeutic strategies to modulate lymphocytes in health and disease. PMID- 30294970 TI - Spatial and temporal coordination of antiviral responses by group 1 ILCs. AB - Group 1 innate lymphocytes consist of a phenotypically, spatially, and functionally heterogeneous population of NK cells and ILC1s that are engaged during pathogen invasion. We are only beginning to understand the context dependent roles that different subsets of group 1 innate lymphocytes play during homeostatic perturbations. With a focus on viral infection, this review highlights the organization and regulation of spatially and temporally distinct waves of NK cell and ILC1 responses that collectively serve to achieve optimal viral control. PMID- 30294975 TI - Polyketide and Prenylxanthone Derivatives from the Endophytic Fungus Aspergillus sp. TJ23. AB - Eight secondary metabolites, including a new polyketide, named asperetide (1) and a new prenylxanthone derivative, called asperanthone (4), and six known compounds, (S)-3-butyl-7-methoxyphthalide (2), ruguloxanthone C (3), tajixanthone hydrate (5), tajixanthone methanoate (6), salimyxin B (7), and ergosterol (8), were isolated and identified from the medicinal plant-derived fungus, Aspergillus sp. TJ23. The new structures and their absolute configurations were elucidated via multiple methods, including 1D- and 2D-NMR, HR-ESI-MS, UV, IR, and the electronic circular dichroism (ECD) calculations. All of the isolates were characterized from the strain for the first time. The in vitro bioassay showed that compounds 3-5 and 8 exerted inhibitory activities against five cancer cell lines (B16, MDA-MB-231, 4T1, HepG2, and LLC) with IC50 values ranging from 5.13 to 36.8 MUm. PMID- 30294974 TI - Exercise during hemodialysis does not affect the phenotype or prothrombotic nature of microparticles but alters their proinflammatory function. AB - Hemodialysis patients have dysfunctional immune systems, chronic inflammation and comorbidity-associated risks of cardiovascular disease (CVD) and infection. Microparticles are biologically active nanovesicles shed from activated endothelial cells, immune cells, and platelets; they are elevated in hemodialysis patients and are associated with chronic inflammation and predictive of CVD mortality in this group. Exercise is advocated in hemodialysis to improve cardiovascular health yet acute exercise induces an increase in circulating microparticles in healthy populations. Therefore, this study aimed to assess acute effect of intradialytic exercise (IDE) on microparticle number and phenotype, and their ability to induce endothelial cell reactive oxygen species (ROS) in vitro. Eleven patients were studied during a routine hemodialysis session and one where they exercised in a randomized cross-over design. Microparticle number increased during hemodialysis (2064-7071 microparticles/MUL, P < 0.001) as did phosphatidylserine+ (P < 0.05), platelet-derived (P < 0.01) and percentage procoagulant neutrophil-derived microparticles (P < 0.05), but this was not affected by IDE. However, microparticles collected immediately and 60 min after IDE (but not later) induced greater ROS generation from cultured endothelial cells (P < 0.05), suggesting a transient proinflammatory event. In summary IDE does not further increase prothrombotic microparticle numbers that occurs during hemodialysis. However, given acute proinflammatory responses to exercise stimulate an adaptation toward a circulating anti-inflammatory environment, microparticle-induced transient increases of endothelial cell ROS in vitro with IDE may indicate the potential for a longer-term anti-inflammatory adaptive effect. These findings provide a crucial evidence base for future studies of microparticles responses to IDE in view of the exceptionally high risk of CVD in these patients.

AB - AIMS: Success in treating patients with atypical parkinsonian syndromes, namely progressive supranuclear palsy (PSP), cortico-basal degeneration (CBD), multiple system atrophy (MSA), Parkinson's disease with dementia (PDD), and Lewy body dementia with (LBD), remains exceedingly low. The present work overviews the most influential research literature collected on MEDLINE, ISI Web of Science, Cochrane Library, and Scopus for available treatment in atypical parkinsonisms without time restriction. DISCUSSION: Transdermal rotigotine, autologous mesenchymal stem cells, tideglusib, and coenzyme Q10 along with donepezil, rivastigmine, memantine, and the deep brain stimulation have shown some benefits in alleviating symptoms in APS. Moreover, many new clinical trials are ongoing testing microtubule stabilizer, antitau monoclonal antibody, tau acetylation inhibition, cell replacement, selective serotonin reuptake inhibitor, active immunization, inhibition of toxic alpha-synuclein oligomers formation, and inhibition of microglia. CONCLUSION: A detailed knowledge of the pathological mechanism underlying the disorders is needed, and disease-modifying therapies are required to offer better therapeutic options to physician and caregivers of APS patients.

AB - Oats produce avenacins, antifungal triterpenes that are synthesized in the roots and provide protection against take-all and other soilborne diseases. Avenacins are acylated at the carbon-21 position of the triterpene scaffold, a modification critical for antifungal activity. We have previously characterized several steps in the avenacin pathway, including those required for acylation. However, transfer of the acyl group to the scaffold requires the C-21beta position to be oxidized first, by an as yet uncharacterized enzyme. We mined oat transcriptome data to identify candidate cytochrome P450 enzymes that may catalyse C-21beta oxidation. Candidates were screened for activity by transient expression in Nicotiana benthamiana. We identified a cytochrome P450 enzyme AsCYP72A475 as a triterpene C-21beta hydroxylase, and showed that expression of this enzyme together with early pathway steps yields C-21beta oxidized avenacin intermediates. We further demonstrate that AsCYP72A475 is synonymous with Sad6, a previously uncharacterized locus required for avenacin biosynthesis. sad6 mutants are compromised in avenacin acylation and have enhanced disease susceptibility. The discovery of AsCYP72A475 represents an important advance in the understanding of triterpene biosynthesis and paves the way for engineering the avenacin pathway into wheat and other cereals for control of take-all and other diseases. PMID- 30294979 TI - The aggressive child. AB - Aggression in children is a common transdiagnostic symptom associated with a wide range of developmental and mental health problems. It emerges early and without intervention, may increase in severity as the child grows stronger. Aggressive children are more likely to experience physical and mental illness, unemployment, poverty and forensic problems as adults. Strategies to prevent aggression must address risk factors: low maternal education, adolescent pregnancy, in utero exposure to tobacco and alcohol, poverty, coercive parenting, childhood maltreatment and bullying victimisation. The aggressive child requires a comprehensive assessment to identify and manage underlying or comorbid problems, to understand the reasons for the aggressive behaviour and to detect modifiable factors that exacerbate or perpetuate the aggression. Psychosocial interventions include parenting skills training and child-directed cognitive behavioural therapy, whereas pharmacotherapy may be used to treat underlying developmental or mental health problems or to manage the aggression. PMID- 30294978 TI - Occupational radiation exposure to nursing staff during cardiovascular fluoroscopic procedures: A review of the literature. AB - Fluoroscopy is a method used to provide real time x-ray imaging of the body during medical procedures to assist with medical diagnosis and treatment. Recent technological advances have seen an increase in the number of fluoroscopic examinations being performed. Nurses are an integral part of the team conducting fluoroscopic investigations and are often located close to the patient resulting in an occupational exposure to radiation. The purpose of this review was to examine recent literature which investigates occupational exposure received by nursing staff during cardiovascular fluoroscopic procedures. Articles published between 2011 and 2017 have been searched and comprehensively reviewed on the referenced medical search engines. Twenty-four relevant studies were identified among which seventeen investigated nursing dose comparative to operator dose. Seven researched the effectiveness of interventions in reducing occupational exposure to nursing staff. While doctors remain at the highest risk of exposure during procedures, evidence suggests that nursing staff may be at risk of exceeding recommended dose limits in some circumstances. There is also evidence of inconsistent use of personal protection such as lead glasses and skull caps by nursing staff to minimize radiation exposure. Conclusions: The review has highlighted a lack of published literature focussing on dose to nurses. There is a need for future research in this area to inform nursing staff of factors which may contribute to high occupational doses and of methods for minimizing the risk of exposure, particularly regarding the importance of utilizing radiation protective equipment. PMID- 30294980 TI - Transgender adolescents and legal reform: How improved access to healthcare was achieved through medical, legal and community collaboration. AB - Transgender children and adolescents face hardships in all domains of their lives, with many experiencing family rejection, social exclusion, discrimination, bullying and assaults. The mental health implications of these experiences include high rates of depression, anxiety, self-harm and attempted suicide. Gender-affirming social support and medical treatment has been shown to ameliorate the poor mental health outcomes of transgender youth, with those who are supported in their social and medical transition reporting rates of depression and self-worth equivalent to general population levels. Advocacy efforts that improve access to support and medical treatment are therefore likely to produce significant positive health and well-being outcomes for this vulnerable population. The transgender community in Australia identified the legal restrictions placed on children and adolescents accessing medical treatment as a significant barrier to positive psychological well-being. Australian law, unique internationally, required the parents of transgender adolescents to apply for court authorisation prior to the commencement of their child's gender affirming medical treatment. Concerned by the harm created by this process, a coalition of experts, including transgender children, adolescents and their parents, as well as academic and clinical experts in the fields of law and medicine, was created to advocate for reform. Over a period of approximately 4 years, a collaborative process was undertaken, which ultimately led to law reform and improved access to medical treatment for the transgender community. PMID- 30294981 TI - Sleep in children with neurodevelopmental difficulties. AB - Sleep disorders in children with neurodevelopmental disorders are complex and reflect underlying genetic/biological and behavioural components. The sleep disorders are the same as in the typically developing child, although there may be some modifications to the presentation or the frequency depending on the phenotype. Consideration of the known phenotypes and environmental issues are important in defining management strategies. Despite this complexity, defined behavioural strategies with good sleep hygiene can have a significant effect on the sleep problem and on parental management of the behaviours. PMID- 30294982 TI - Transition to adult mental health services for young people with an intellectual disability. AB - People with intellectual disabilities (ID) experience high rates of mental health problems, particularly during the period of transition to adulthood. It is therefore important that the transition from child- to adult-oriented health services for people with ID is well managed to ensure appropriate orientation to ongoing adult mental health care. The purpose of this paper is to summarise the impact and experience of transition to adult mental health care for people with ID and those who support them, as well as issues related to current policy and practice in this area. Several opportunities for improvement are identified in the broad areas of policy, service structure and organisation, research and workforce capacity. Enhancements in these areas will lead to improved outcomes for young people with ID transitioning from child- to adult-oriented mental health care. PMID- 30294983 TI - Specific learning disability. AB - Specific learning disabilities (SLD) have an impact on discrete areas of academic function. They result in a level of difficulty that is unexpected when considered in the context of a student's overall intellectual and academic competence. A common example is dyslexia, an SLD that affects the acquisition of literacy. Medical professionals have an important role to play in the evaluation and management of SLD. The medical role is founded on the fact that these conditions are biologically based and have the potential to cause significant harm for the developing child. Even if details of biological causation are not possible to demonstrate for individual children, medical professionals may, nevertheless, make an important judgement call regarding the likelihood of aetiology. When learning problems are medically based, it is clearly unreasonable to expect children to do more than they are able and to learn faster than is reasonable. Advocacy around these biological presumptions and their implications is a major contribution to the well-being of children who have SLD. PMID- 30294984 TI - Responding to fetal alcohol spectrum disorder in Australia. AB - Fetal alcohol spectrum disorder (FASD) is a significant public health issue in Australia that is poorly diagnosed, chronic and costly. FASD is a diffuse acquired brain injury secondary to prenatal alcohol exposure. The prevalence rate of FASD among the general population in Australia is currently unknown; however, an Australian study in a selected high-risk population reported some of the highest rates of FASD in the world. A common misconception among clinicians is that a child must have 'the face' of FASD to have the disorder. This is incorrect. The three sentinel facial features only occur in the minority of individuals with FASD. FASD should be considered as a 'whole body' disorder as increased susceptibility to chronic health problems suggests suboptimal in utero environments places the individual at risk of later disease. Clinicians are reluctant to consider FASD as a possible diagnosis because of the concern of inducing stigma; however, this concern is neither supported by the evidence nor patient stories. The Australian Guide to the Diagnosis of FASD is now available to assist health professionals in providing timely and accurate diagnoses, which can lead to improved outcomes via evidence-based intervention and is an important first step in future prevention. PMID- 30294985 TI - Models of care in neurodevelopmental-behavioural paediatrics. AB - In Australia, children with developmental-behavioural presentations experience large variations in both access to specialist health care and in the care they receive from specialists. A recent survey of members of the Neurodevelopmental and Behavioural Paediatric Society of Australasia confirmed that this variation persists even among public services provided by paediatric doctors with a special interest in this field. In this article, we discuss the challenges of establishing a single model of developmental-behavioural paediatric care and set out principles of best practice in the field. An essential part of working towards excellence in care involves defining our outcomes, utilising standardised measures, collecting systematic data, working in partnership with families to address their concerns and goals, participating in reflective practice and demonstrating a willingness to change current practice based on the results. PMID- 30294986 TI - Anxiety-related disorders: An overview. AB - Anxiety-related disorders are common in the child and adolescent population. They cause significant distress, which can affect social, emotional, family and academic functioning. They frequently present in general paediatric and primary care settings. Comprehensive assessment should include the child as well as parent and family functioning because anxiety-related disorders in other family members are common and, if untreated, can affect outcomes for the child. There are good evidence-based psychological interventions available, which should be the first line of treatment offered; accessing appropriate therapies for an adequate duration of treatment can, however, be challenging. Medication, particularly selective serotonin reuptake inhibitors, may have a role to play but should be used in the context of psychologically based therapies. Prevention of anxiety-related disorders in childhood is a major public health issue. Prevention programmes are available and should commence in the antenatal period through infancy, early childhood and adolescence, promoting positive attachments and resilience. PMID- 30294987 TI - Motor impairments in children: More than just the clumsy child. AB - Developmental co-ordination disorder is a motor skill disorder that affects an estimated 5-6% of children but lacks recognition and understanding, leading to under-diagnosis. Essential for diagnosis is a marked impairment in motor co ordination that significantly impacts daily living, including education. Although 'clumsiness' is often dismissed, the impact of this disorder is significant and extends beyond motor skills into physical and psychological health and educational and vocational success. This is discussed here with regard to the framework of the International Classification of Functioning, Disability and Health. This review also discusses the importance of an accurate, early diagnosis and factors that inhibit this; dual diagnosis with comorbid neurodevelopmental disorders; the multidisciplinary approach to diagnosis and the role of the paediatrician within this; and current evidence regarding the most effective interventions. PMID- 30294988 TI - Child with multiple problems: Clinical complexity and uncertainty. AB - When practising neurodevelopmental-behavioural paediatrics, responsibility rests with the individual clinician to interpret research evidence in their daily work. This is not necessarily an easy task. Children do not usually present with single, easily definable problems. Complexity and uncertainty are present from the outset due to heterogeneity inherent in the diagnoses available, patterns of comorbid problems and the unique challenges of each child's social context. This article examines the resulting clinical challenge and offers potential responses. Rather than striving to eliminate uncertainty with strategies such as extensive assessment, the goal is to work effectively and efficiently within the limits of what can be readily known. Suggested strategies address complexity by considering the components of what is going on (biological, developmental, transactional) as hypotheses shared within each child's system of care. These hypotheses can then be tested and revised systematically as further information arises along the journey of treatment and longitudinal care. PMID- 30294989 TI - Children who soil: A review of the assessment and management of faecal incontinence. AB - Soiling is a common and distressing condition affecting children. In the vast majority of patients, it is associated with constipation. Most constipation is functional and is best thought of as difficulty achieving adequate bowel emptying. In a small minority of patients, there is no associated constipation, so-called non-retentive faecal incontinence. The aetiology of this latter condition in children remains unclear. The mainstay of management in all cases is a regular toileting programme, together with laxatives as required. This must be individualised considering the diagnosis, the age of the child and the psychosocial factors affecting the child and family. The diagnosis is made with a thorough history and examination, supplemented in some cases with targeted investigations. Engaging the child and family in a long-term treatment programme (at least 6 months to 2 years) is essential for treatment success. The following clinical practice guideline and algorithm for the assessment and management of children who soil represents consensus opinion using available evidence. PMID- 30294990 TI - Use of psychotropic medications in general paediatric practice. AB - Paediatricians contribute the greatest proportion of prescriptions for psychotropic medication to children between the ages of 3 and 14 years in Australia. Medications indicated for attention-deficit hyperactivity disorder are the most commonly prescribed, followed by antidepressants and antipsychotics. Outside treatment for attention-deficit hyperactivity disorder, most prescribing is 'off label'. There are few searchable, up-to-date resources to guide psychotropic prescribing to children. The skill level required to manage pharmacotherapy is determined by the condition and the characteristics of the patient. Psychotropic medication should always be considered within the context of other interventions and environmental factors that influence emotions, cognition and behaviour. Beware the 'medication fallacy' that arises out of a misconception that if one medication does not work, there must be another that will. PMID- 30294991 TI - Diagnosing cerebral palsy in full-term infants. AB - More than 50% of infants with cerebral palsy (CP) are born at or near term, with the vast majority having pre- or perinatally acquired CP. While some have a clinical history predictive of CP, such as neonatal encephalopathy or neonatal stroke, others have no readily identifiable risk factors. Paediatricians are often required to discriminate generalised motor delay from a variety of other diagnoses, including CP. This paper outlines known causal pathways to CP in term born infants with a focus on differential diagnosis. Early and accurate diagnosis is important as it allows prompt access to early intervention during the critical periods of brain development. A combination of clinical history taking, standard clinical examination, neuroimaging and genetic testing should be started at the time of referral. Attention to the investigation of common comorbidities of CP, including feeding and sleep difficulties, and referral to early intervention are recommended. PMID- 30294992 TI - Attention deficit hyperactivity disorder: Some challenging clinical scenarios. AB - Paediatricians generally have good skills in the assessment and management of attention deficit hyperactivity disorder. In most cases this is not difficult - the paediatrician's role is clear, and evidence-based treatment can be delivered. There are however some clinical situations which present diagnostic, ethical and/or management dilemmas for paediatricians in relation to possible attention deficit hyperactivity disorder. This Viewpoint article addresses some of these scenarios. PMID- 30294993 TI - Investigating the child with intellectual disability. AB - The search for causation is a key component of the assessment of the child with intellectual disability. Historically, a specific diagnosis has been achievable in only a small minority of these children, but over the last decade, this has changed dramatically such that a specific diagnosis is now possible in about half of all children with intellectual disability. This improvement has been driven by major advances in genetic-testing technologies, the most important of which are chromosome microarray and whole exome sequencing. Simultaneously, these technological advances have revealed many new genetic syndromes that had previously escaped clinical recognition, and demonstrated that the majority of severe intellectual disability is caused by pathogenic gene variants that arise de novo in the child. Although access to genomic testing is currently limited, evidence from health economic studies suggests that this testing is most cost effective when performed early in the patient's diagnostic journey. PMID- 30294994 TI - Aetiology of childhood apraxia of speech: A clinical practice update for paediatricians. AB - Childhood apraxia of speech (CAS) is a rare disorder of childhood that can leave a watermark of the impacts throughout the lifetime. Since being first described in the 1950s, aetiological insights have been limited. At a neurobiological level, clinical MRI scans fail to reveal overt neural anomalies in individual cases with CAS, although quantitative MRI methods have revealed subtle brain anomalies at a group level. Dramatic insights, however, occurred in the past decade from the discovery of genetic pathways underlying the phenotype. Several single genes and copy number-variant conditions are now associated with CAS either in relative isolation, as in the case of FOXP2 variants, or most typically in association with other neurodevelopmental conditions, such as epilepsy, intellectual disability, motor impairment and autism. CAS requires careful differential diagnosis from other childhood speech disorders, but when a severe and persistent diagnosis is confirmed, a genetic aetiology should increasingly be pursued. PMID- 30294995 TI - Recognition of attachment difficulties and developmental trauma is the responsibility of all paediatricians. AB - This article provides an overview of attachment theory, developmental trauma and trauma-informed care for paediatricians. The impact of difficult or impoverished parent-child relationships on brain development and long-term health is now well known. Recent neuroscience research reveals the adverse neurological impacts of developmental trauma and supports the biological basis of attachment theory. There is also an increasing body of evidence that childhood adversity is common and impacts physical and mental health throughout the life-span. Comprehensive paediatric assessment should include an understanding of attachment difficulties and developmental trauma. Viewing children and their families through a 'trauma informed lens' can provide critical insights into their clinical presentation and care needs. All paediatricians should be providing and practicing trauma-informed care. PMID- 30294996 TI - Tics and Tourette syndrome. AB - Tourette syndrome is a heterogeneous disorder. The genetic basis is complex, and both in utero and ex utero environmental factors may modify the phenotypic expression of the disorder. Inflammation related to aberrations in immune activation appears to play a pathogenic role in some cases. Multiple neurochemical pathways are involved. Rather than being a pure movement problem, tics are now understood to also have a sensory component. This has resulted in new psychological therapeutic strategies and other potential treatments. Furthermore, comorbidities are common, particularly attention-deficit hyperactivity disorder, anxiety and obsessive-compulsive disorder, and often cause more difficulties than the tics. The approach to treatment is dependent on the degree and types of impairment. For many patients, education, acceptance and understanding are all that is needed. In more severe cases, psychological and/or pharmacological interventions may be indicated. In this article, the clinical features and pathophysiology of Tourette syndrome are reviewed, and a pragmatic management approach is discussed. PMID- 30294997 TI - Autism: One or many spectrums? AB - Our conceptualisation of autism spectrum disorder has changed over time, with recent classifications reflecting a heterogeneous clinical presentation now regularly encountered in routine general paediatric practice. As the prevalence of autism and associated demands for services have increased so has research into understanding the cause and trials aimed at providing best care and intervention. However, the heterogeneity of autism has meant that no single aetiology can account for all differences in presentation, and not all children benefit from broad-based interventions. Now is the time to rethink how best to understand individual differences in order to focus research efforts and take steps towards more sophisticated strategies that go beyond the behaviours we look for when making an autism diagnosis. We suggest adopting a dimensional approach to autism assessment, with the consideration of eight spectrums of abilities, ways of thinking and behaviour. This eight-spectrum approach will assist clinicians to consider each individual's strengths and needs and personalise interventions and support accordingly. Profiling individual skills across these dimensions may also provide researchers with a greater capacity to link causal pathways with specific phenotypes, which is needed to develop precision medicine for autism.

AB - Enuresis (bedwetting) is common in school-aged children and can impact health, psychosocial well-being and quality of life. Although effective treatment is available, treatment resistance is encountered in about 50%. This paper discusses the management of treatment-resistant enuresis from a multidisciplinary perspective. Causes of treatment resistance include lower urinary tract problems, constipation, incorrect alarm training techniques, sleep disorders including sleep apnoea and psychological comorbidities. Practical suggestions to address treatment resistance are offered utilising expertise from clinicians from different disciplines. PMID- 30295000 TI - To go or not to go: School refusal and its clinical correlates. AB - Problematic school refusal that is child motivated is a serious but common presentation and a child psychiatric emergency. Mental health professionals, paediatricians, educators and parents are often required to work in tandem to alleviate concerns due to this. Prolonged absence from school may lead to immediate (educational backwardness) and far-reaching effects (psycho-social and educational maladjustment). Psychiatric morbidity is high in school-refusing children presenting to secondary and tertiary services and is associated with temperamental, family and environmental adversities. Outcomes can vary according to their age, duration of school refusal and environmental variables. PMID- 30295001 TI - Lactic acid production from sugarcane bagasse hydrolysates by Lactobacillus pentosus: Integrating xylose and glucose fermentation. AB - Lactic acid, traditionally obtained through fermentation process, presents numerous applications in different industrial segments, including production of biodegradable polylactic acid (PLA). Development of low cost substrate fermentations could improve economic viability of lactic acid production, through the use of agricultural residues as lignocellulosic biomass. Studies regarding the use of sugarcane bagasse hydrolysates for lactic acid production by Lactobacillus spp. are reported. First, five strains of Lactobacillus spp. were investigated for one that had the ability to consume xylose efficiently. Subsequently, biomass fractionation was performed by dilute acid and alkaline pretreatments, and the hemicellulose hydrolysate (HH) fermentability by the selected strain was carried out in bioreactor. Maximum lactic acid concentration and productivity achieved in HH batch were 42.5 g/L and 1.02 g/L h, respectively. Hydrolyses of partially delignified cellulignin (PDCL) by two different enzymatic cocktails were compared. Finally, fermentation of HH and PDCL hydrolysate together was carried out in bioreactor in a hybrid process: saccharification and co-fermentation with an initial enzymatic hydrolysis. The high fermentability of these process herein developed was demonstrated by the total consumption of xylose and glucose by Lactobacillus pentosus, reaching at 65.0 g/L of lactic acid, 0.93 g/g of yield, and 1.01 g/L h of productivity.

AB - Bioreactors are of interest for gas-to-liquid conversion of stranded or waste industrial gases, such as CO, CH4 , or syngas. Process economics requires reduction of bioreactor cost and size while maintaining intense production via rapid delivery of gases to the liquid phase (i.e., high kL a). Here, we show a novel bioreactor design that outperforms all known technology in terms of gas transfer energy efficiency (kL a per power density) while operating at high kL a (i.e., near 0.8 s-1 ). The reactor design uses a micro-jet array to break feedstock gas into a downward microbubble flow. Hydrodynamic and surfactant measurements show the reactor's advanced performance arises from its bubble breakage mechanism, which limits fluid shear to a thin plane located at an optimal location for bubble breakage. Power dissipation and kL are shown to scale with micro-jet diameter rather than reactor diameter, and the micro-jet array achieves improved performance compared to classical impinging-jets, ejector, or U loop reactors. The hydrodynamic mechanism by which the micro-jets break bubbles apart is shown to be shearing the bubbles into filaments then fragmentation by surface tension rather than "cutting in half" of bubbles. Guided by these hydrodynamic insights, strategies for industrial design are given. (c) 2018 American Institute of Chemical Engineers Biotechnol. Prog., 2018. PMID- 30295003 TI - The "Plan" phase of a Deming cycle: Measurement of quality and outcome of root canal treatments in a university hospital. AB - INTRODUCTION: In many countries, dental students are taught in private or university hospitals where they treat patients under the supervision of teachers. Assessing the quality of root canal treatments (RCT) would provide information about the quality of care patients receive when treated by students. METHODS: This study describes the six-step "Plan" phase of a Plan-Do-Check-Act (PDCA) cycle that identifies and analyses clinical practices in endodontics in a university dental hospital service. RESULTS: Step 3 reported that the proportion of RCTs of adequate quality reached 57.1% and this proportion was significantly decreased when specific indicators for treatment difficulties were present. The proportion of successful RCTs after 1 year was 65.6%, and its variation was influenced by the preoperative periapical status rather than the quality of RCTs. The consensual meeting in Step 6 proposed to introduce three new procedures for the further Do, Check and Act phases of the PDCA cycle. CONCLUSION: This study encourages systematic evaluation of RCTs and provides the first step of the methodology that can be reproduced in private and hospital practices where students are asked to treat patients. PMID- 30295005 TI - Recent Advances in Polyesters for Biomedical Imaging. AB - Several synthetic materials exhibiting contrast imaging properties have become vital to the field of biomedical imaging. Polymeric biomaterials and metals are commonly used imaging agents and can assist in the monitoring of therapy response, migration, degradation, changes in morphology, defects, and image guided surgery. In comparison to metals, most bio and synthetic polymers lack inherent imaging properties. Polymeric biomaterials, specifically polyesters, have gained a considerable amount of attention due to their unique properties including biocompatibility, biodegradation, facile synthesis, and modification capability. Polyester implants and nanomaterials are available on the market or are in clinical trials for many applications including: dental implants, cranio maxilofacial implants, soft tissue sutures and staples, abdominal wall repair, tendon and ligament reconstruction, fracture fixation devices, and coronary drug eluting stents. This review aims to provide a summary of the recent developments of polyesters with bioimaging contrast properties. The three main approaches to prepare bioimaging polyesters (coating, encapsulation, and functionalization) are discussed in depth. Furthermore, commonly used imaging modalities including X-ray computed tomography, magnetic resonance imaging, ultrasound, fluorescence, and radionucleotide polyester contrast agents are highlighted. In each section, examples of impactful bioimaging polyesters in the five major imaging modalities are evaluated. PMID- 30295004 TI - Oxygenation time course and neuromuscular fatigue during repeated cycling sprints with bilateral blood flow restriction. AB - The aim was to evaluate changes in peripheral and cerebral oxygenation, cardiorespiratory, and performance differences, as well as neuromuscular fatigue across multiple levels of blood flow restriction (BFR) during a repeated cycling sprint test to exhaustion (RST). Participants performed three RST (10-sec maximal sprints with 20-sec recovery until exhaustion) with measurements of power output and VO2peak as well as oxygenation (near-infrared spectroscopy) of the vastus lateralis and prefrontal cortex. Neuromuscular fatigue was assessed by femoral nerve stimulation to evoke the vastus lateralis. Tests were conducted with proximal lower limb bilateral vascular occlusion at 0%, 45%, and 60% of resting pulse elimination pressure. Total work decreased with BFR (52.5 +/- 22.9% at 45%, 68.6 +/- 32.6% at 60%, P < 0.01 compared with 0%) as VO2peak (12.6 +/- 9.3% at 45%, 18.2 +/- 7.2% at 60%, compared with 0%, P < 0.01). Decreased changes in muscle deoxyhemoglobin (?[HHb]) during sprints were demonstrated at 60% compared to 0% (P < 0.001). Changes in total hemoglobin concentrations (?[tHb]) increased at both 45% and 60% compared with 0% (P < 0.001). Cerebral ?[tHb] increased toward exhaustion (P < 0.05). Maximal voluntary contraction (MVC), voluntary activation level (VAL), and root mean square (RMS)/M-wave ratio decreased at 60% compared with 0% (P < 0.001, all). MVC and VAL decreased between 45% and 60% (P < 0.05, both). The application of BFR during RST induced greater changes in tissue perfusion (via blood volume, ?[tHb]) suggesting a possible stimulus for vascular blood flow regulation. Additionally, high-intensity sprint exercise with partial ischemia may challenge cerebral blood flow regulation and influence local fatigue development due to protection of cerebral function. PMID- 30295006 TI - Effect of ibuprofen on the efficacy of inferior alveolar nerve block in patients with irreversible pulpitis: A meta-analysis. AB - The aim of this study was to compare preventive ibuprofen administration to placebo on the efficacy of inferior alveolar nerve block in patients with irreversible pulpitis. A search was performed in PubMed, Scopus, Web of Science, LILACS, BBO, Cochrane Library, SIGLE, and grey literature. The risk of bias was evaluated through the Cochrane Collaboration's tool. The quality of evidence was assessed using the GRADE approach. Only seven studies remained for the meta analysis. Administering ibuprofen before anaesthesia increased the success rate of injectable anaesthesia (RR = 1.79; 95% confidence interval (CI) 1.32-2.42; P = 0.0002) even in cases of symptomatic irreversible pulpitis (RR = 1.55; 95% CI 1.05-2.29; P = 0.03). The intensity of pain was lower for ibuprofen (standardised difference means (SMD) = -3.73; 95% CI -6.43 to -1.04; P = 0.007). Ibuprofen as premedication is beneficial for the success of inferior alveolar nerve block. PMID- 30295008 TI - Different faces of neurodegeneration.

PMID- 30295009 TI - The Impact of Nano- and Microstructure on the Stability of Perovskite Solar Cells. AB - Halide perovskites have emerged recently as a promising candidate for the next generation of photovoltaics. Power conversion efficiencies for laboratory-scale devices surpass those of established technologies, such as multicrystalline silicon. However, perovskite solar cells lose their initial efficiency rapidly due to the convolution of several degradation factors, which hinder the process of industrialization. In this review, the important role of the nano- and microstructure of the perovskite layer in the performance and stability of the device are discussed. The defects located predominantly at the grain boundaries within the perovskite film and at the interface of the perovskite with the other materials can compromise the devices' stability. Thus, lowering the surface and interface concentration of defects is a key approach toward long-term stable perovskite solar cells.

AB - Addition of Zr metal particles to MoCx /ZSM-5 in interpellet mixtures (2:1 weight ratio) resulted in maximum single-pass methane conversion of 27 % for dehydroaromatization at 973 K (in significant excess of the equilibrium prescribed circa 10 % conversion at these conditions) and a concurrent 1.4-5.6 fold increase in aromatic product yields due to circumvention of thermodynamic equilibrium limitations by absorptive H2 removal by Zr while retaining cumulative aromatic product selectivity. The absorptive function of the polyfunctional catalyst formulation can be regenerated by thermal treatment in He flow at 973 K, yielding above-equilibrium methane conversion in successive regeneration cycles. H2 uptake experiments demonstrate formation of bulk ZrH1.75 on hydrogen absorption by Zr at 973 K. Cooperation between absorption and catalytic centers distinct in location and function enables circumvention of persistent thermodynamic challenges in non-oxidative methane dehydrogenation.

AB - Supramolecular hydrogels are a class of self-assembled network structures formed via non-covalent interactions of the hydrogelators. These hydrogels capable of responding to external stimuli are considered to be smart materials due to their ability to undergo sol-gel and/or gel-sol transition upon subtle changes in their surroundings. Such stimuli-responsive hydrogels are intriguing biomaterials with applications in tissue engineering, delivery of cells and drugs, modulating tissue environment to promote innate tissue repair, and imaging for medical diagnostics among others. This review summarizes the recent developments in stimuli-responsive supramolecular hydrogels and their potential applications in regenerative medicine. Specifically, various structural aspects of supramolecular hydrogelators involved in self-assembly, the role of external stimuli in tuning/controlling their phase transitions, and how these functions could be harnessed to advance applications in regenerative medicine are focused on. Finally, the key challenges and future prospects for these versatile materials are briefly described. PMID- 30295011 TI - Arterial stiffness mediates the effect of salt intake on systolic blood pressure. AB - Accumulating evidence indicates that higher levels of salt intake are associated with higher blood pressure levels. The aim of our analysis was to test the hypothesis that the effect of urinary sodium excretion (UNaV) on systolic blood pressure (SBP) is mediated through estimated glomerular filtration rate (eGFR) and arterial stiffness and also to test the direction of the relationship between eGFR and arterial stiffness, in both hypertensive and normotensive patients. We assessed the potential for connection between UNaV and SBP and mediators (eGFR and pulse wave velocity [PWV]) of this relationship using structural equation models of data from 1599 adults >=18 years of age and without chronic kidney disease who participated in the Third Epidemiologic Study concerning the Prevalence of Arterial Hypertension and Cardiovascular Risk in Romania (SEPHAR III). In hypertensive patients, the indirect effect, mediated through PWV, of UNaV on SBP was 23.9% and 27.7% of the total effect of UNaV on SBP, while in normotensive patients the contribution of PWV to the total effect of UNaV on SBP was slightly lower (15.9% and 18.3% of the total effect of UNaV on SBP). Taken together, our findings support the conclusion that UNaV influences SBP, both directly and indirectly, through the effect on PWV.

AB - BACKGROUND: Communication partner training (CPT) programmes for health and care staff working with people with the neurologically based communication disorders associated with stroke, traumatic brain injury (TBI) and dementia are efficacious in improving communication. However, current programmes are lengthy and disorder specific, and therefore may not be suitable as staff training tools in environments with people with multiple communication disorders, and services with a variety of neurological populations. AIMS: To identify common and distinct components of CPT programmes for stroke, TBI and dementia in order to determine whether there are common delivery methods and content that can be consolidated to improve implementation of CPT in health and care services. METHODS & PROCEDURES: A qualitative enquiry was used. Four CPT programmes targeting three disorders were identified from systematic reviews and literature searches. Programme data were recorded onto data sheets from manuals, study articles and supplementary materials, and were categorized using the Intervention Taxonomy (ITAX). Content analysis and elements of constant comparative analysis were employed to analyse the CPT programmes. OUTCOMES & RESULTS: Delivery characteristics were similar across all four programmes. All were delivered face to face in either group or individual contexts. However, duration varied from 1 to 35 h. Six of the 12 categories of information provided were common across all programmes, including 'strategy' 'background to disorder', 'information about communication', 'information about program', 'negative behaviours to avoid' and 'purpose of program'. Programmes differed in the types of skill-building techniques used, with the most common being videos (3/4 programmes), discussions (2/4 programmes) and trainer demonstrations (2/4 programmes). While strategies provided to trained partners targeted similar domains of communication, only 3/96 individual strategies were common to all programmes. CONCLUSIONS & IMPLICATIONS: There are both common and distinct components in content and delivery methods across CPT programmes. Further research is needed to evaluate the distinct components of the programmes, to determine which individual strategies are efficacious, and which approach to skill-building techniques is most effective. The present study has contributed a comprehensive list of programme components, which can form a basis for describing and refining CPT programmes in future. PMID- 30295015 TI - Multifunctional, Superelastic, and Lightweight MXene/Polyimide Aerogels. AB - 2D transition metal carbides and nitrides (MXenes) have gained extensive attention recently due to their versatile surface chemistry, layered structure, and intriguing properties. The assembly of MXene sheets into macroscopic architectures is an important approach to harness their extraordinary properties. However, it is difficult to construct a freestanding, mechanically flexible, and 3D framework of MXene sheets owing to their weak intersheet interactions. Herein, an interfacial enhancement strategy to construct multifunctional, superelastic, and lightweight 3D MXene architectures by bridging individual MXene sheets with polyimide macromolecules is developed. The resulting lightweight aerogel exhibits superelasticity with large reversible compressibility, excellent fatigue resistance (1000 cycles at 50% strain), 20% reversible stretchability, and high electrical conductivity of ~4.0 S m-1 . The outstanding mechanical flexibility and electrical conductivity make the aerogel promising for damping, microwave absorption coating, and flexible strain sensor. More interestingly, an exceptional microwave absorption performance with a maximum reflection loss of 45.4 dB at 9.59 GHz and a wide effective absorption bandwidth of 5.1 GHz are achieved.

AB - Acquired resistance inevitably occurs after initial treatment with first generation EGFR-tyrosine kinase inhibitors (TKIs). Several mechanisms have been identified, including EGFR T790M mutation and HER2 amplification. Herein, we present the case of a patient who progressed on first-generation EGFR-TKIs and developed EGFR T790M mutation, HER2 amplification, and HER2 mutation. The administration of single-agent osimertinib yielded an inconsistent response, with worsened pleural effusion and a reduction to lung metastases, but remarkably, a partial response was achieved after four weeks of treatment with combined osimertinib and afatinib, with grade 1 rash and grade 2 diarrhea. Our findings indicate an overlap of T790M, HER2 amplification, and HER2 mutation, which is rarely reported. Moreover, HER2 mutation was identified during the development of resistance, suggesting that HER2 mutation may cause resistance to first generation EGFR-TKIs. PMID- 30295017 TI - Exaggerated health news: association between exaggeration in university press releases and exaggeration in news media coverage AB - Objective: To determine how often press releases and news articles contain exaggeration and to locate its origin in the trajectory from research paper to news article. Design: Retrospective quantitative content analysis. Method: We analysed press releases on health-related research published by Dutch universities and university medical centres in 2015 (n = 129) as well as news media articles related to those press releases (n = 185). Results: 20% of press releases and 29% of news articles exaggerated the conclusion or causal claim. Explicit health advice was, when present, exaggerated in 7% of press releases and 10% of news articles. When press releases exaggerated the conclusion or causal claim, 92% of associated news articles contained the same exaggeration. When the conclusion was not exaggerated in the press release, 6% of the news articles was exaggerated. The relative chance for exaggerated news associated with exaggerated press releases was 16.08 (95% CI: 7.35-35.18). Exaggerated press releases were associated with news articles more frequently. The relative chance for news articles to be associated with exaggerated press releases vs. a non-exaggerated press release was 1.45 (95% CI: 1.02-2.04). Conclusion: Exaggeration in health related news is strongly correlated with exaggeration in the original press release and occurs in more than 1 in 5 articles. Monitoring and, if necessary, improving the accuracy and correctness of academic press releases seem to be important measures to improve the quality of health related news. : Conflict of interest and financial support: I.

PMID- 30295018 TI - Nonvolatile Memory Based on Molecular Ferroelectric/Graphene Field Effect Transistor. AB - Ferroelectric thin films are extensively attractive as next-generation nonvolatile memories. Recently, molecular ferroelectrics (MFe), as an emerging new class, have been a new research focus because of their desirable characteristics such as good solution processability, tunable chemical properties, and bio-friendly compositions. However, traditional uniaxial MFe only possess one polar axis which greatly limits their application, as it requires restricted orientational control in single crystal. To achieve macroscopic ferroelectricity and thus fully realize technological advantages of MFe, development of multiaxes is imperative to maximize effective polarization in specific crystallographic orientations. Herein, we present an early exploration on polycrystalline multiaxial MFe thin films of [Hdabco][ReO4] with a two dimensional graphene hybrid nonvolatile memory device. The polarization switching of MFe is experimentally realized by the nonvolatile modulation of two current states in graphene. Such a hybrid device can exhibit large memory window ~35 V implying its great potential in memory applications. Hence, by taking the advantages of multiple polarization axes of MFe, the low cost and large area MFe/graphene hybrid memory manifests new possibilities for the integration of these materials as flexible next generation memory devices.

AB - We have developed a rhodium-catalyzed carbonylative annulation methodology for the direct preparation of thiochromenones.

PMID- 30295020 TI - Acid-Induced Gelation of Caseins Glycated with Lactose: Impact of Maillard Reaction-Based Glycoconjugation and Protein Cross-Linking. AB - During food processing or storage, milk proteins can react with reducing sugars via the Maillard reaction (glycation), which may alter their techno-functional properties. The aim of this study was to investigate the relationship between molecular changes of casein occurring during different stages of the Maillard reaction and its acid-induced gelling properties. Therefore, sodium caseinate was heated in a dry state at 60 degrees C in the presence of lactose and analyzed for structural modifications by determining Amadori compounds (glycoconjugation) indirectly as furosine, the total lysine modification, and the extent of protein cross-linking. For techno-functional characterization, acid-induced gels were prepared by the addition of glucono-delta-lactone and evaluated by measuring pH kinetics during gel formation, gel strength, and water holding capacity. The time to reach pH 4.6 during the gelation process was significantly delayed with increasing extent of the Maillard reaction. Glycation with lactose also led to a significant increase in gel strength and water holding capacity. The increase in gel stability was rather independent from the amount of sugars covalently bound to the proteins during the early phase of the Maillard reaction but strongly correlated to the degree of protein polymerization. Small- and medium-sized casein oligomers, formed during advanced stages of the Maillard reaction, contributed considerably to the formation of stronger gels with higher water holding capacity, whereas a sharp increase in the relative amount of the polymer fraction observed during prolonged cross-linking processes caused a spontaneous destabilization of the gel network. Knowledge about structure-function relationships on a molecular level can provide useful information to control food texture by raw material quality. PMID- 30295021 TI - In Situ Formation of Micropore-Rich Titanium Dioxide from Metal-Organic Framework Templates. AB - Phase and porosity control in titanium dioxide (TiO2) is essential for the optimization of its photocatalytic activity. However, concurrent control over these two parameters remains challenging. Here, a novel metal-organic framework templating strategy is demonstrated for the preparation of highly microporous anatase TiO2. In situ encapsulation of Ti precursor in ZIF-8 cavities, followed by hydrolysis and etching, produces anatase TiO2 with a high Brunauer-Emmett Teller surface area of 335 m2.g-1 and a micropore surface area ratio of 48%. Photocatalytic hydrogen generation catalyzed by the porous TiO2 can reach a rate of 2459 MUmol.g-1.h-1. The measured photocatalytic activity is found to be positively correlated to the surface area, highlighting the importance of porosity control in heterogeneous photocatalysts. PMID- 30295022 TI - Carbon-Fiber Microbiosensor for Monitoring Rapid Lactate Fluctuations in Brain Tissue Using Fast-Scan Cyclic Voltammetry. AB - Recent studies have described a role for lactate in brain energy metabolism and energy formation, challenging the conventional view that glucose is the principle energy source for brain function. To date, lactate dynamics in the brain are largely unknown, limiting insight into function. We addressed this by developing and characterizing a lactate oxidase-modified carbon-fiber microelectrode coupled with fast-scan cyclic voltammetry. This new tool boasts a sensitivity for lactate of 22 +/- 1 nA.mM-1 and LOD of 7.0 +/- 0.7 MUM. The approach has enabled detection of rapid lactate fluctuations with unprecedented spatiotemporal resolution as well as excellent stability, selectivity, and sensitivity. The technology was characterized both in vitro and in vivo at discrete recording sites in rat striatum. We provide evidence that striatal lactate availability increases biphasically in response to electrical stimulation of the dopaminergic midbrain in the anesthetized rat. This new tool for real-time detection of lactate dynamics promises to improve understanding of how lactate availability underscores neuronal function and dysfunction. PMID- 30295023 TI - Organic Media Superwettability: On-Demand Liquid Separation by Controlling Surface Chemistry. AB - Superwettability involving water affinity has demonstrated prominent advantages in oil-water separation. However, superwetting surfaces in nonpolar liquid-polar liquid systems are rarely explored for the separation of organic liquids. In this work, a protocol of elaborately controlling surface chemistry is presented to construct dual superlyophobic surfaces for polar or nonpolar liquids in opposite organic media. On two kinds of silver-roughened copper coatings, a polar hydroxyl group is subtly integrated with nonpolar perfluoroalkyl chain at the nanoscale. Prewetted by one organic liquid, the obtained dual superlyophobic mesh can selectively intercept other immiscible organic liquids, realizing high-efficiency on-demand separation. In theory, the dual superlyophobic surfaces in organic media are strongly dependent on their affinity toward polar liquids and the surface roughness. The discovery may promote the development of organic liquid related interfacial materials. PMID- 30295025 TI - Modeling QCM-D Response to Deposition and Attachment of Microparticles and Living Cells. AB - Quartz crystal microbalance with dissipation monitoring (QCM-D) is a powerful tool for studying adhesion, yet its use for analyzing the deposition of microparticles and living cells on surfaces has been hampered by difficulties in interpretation. Here we report a new quantitative model of QCM-D response, presented as an equivalent acoustic impedance circuit. As an essential feature, the particle interaction with surrounding fluid is modeled by relations for a freely oscillating rotating and translating sphere in an unbounded fluid, which is a valid approximation for microparticles. This helps deduce from the measured reponse the parameters pertinent to the contact mechanics. We use the model to analyze deposition of different microparticles as well as Pseudomonas fluorescens bacteria on several substrates using QCM-D combined with real-time microscopy. The parameter space is increased by varying particle type and size, substrate surface chemistry and rigidity, and ionic strength of the solution, which allows observation of diverse responses and transition from inertial to elastic loading, including rarely observed resonant regimes. Ultimately, we find that the model describes reasonably well the observed response for different microparticles and substrates, as well as for bacteria, and enables extraction of the contact characteristics in elastic and mixed loading regimes. It also reveals discrepancies between measured and anticipated parameters for large particles. The new model can be a useful tool for interpreting and quantifying QCM-D data on the adhesion of particles and living cells to surfaces, including time-dependent adhesion phenomena. PMID- 30295024 TI - Synthesis of Piperine Analogs Containing Isoxazoline/Pyrazoline Scaffold and Their Pesticidal Bioactivities. AB - In continuation of our program to discover new potential pesticidal agents, thirty-one piperine analogs containing isoxazoline/pyrazoline scaffold were prepared, and confirmed by infrared spectra, proton/carbon-13 nuclear magnetic resonance spectra, and high-resolution mass spectra. The structures of compounds VIIb and VIIIc were further determined by 1H-1H COSY spectra. Especially the configuration of compound VIIIc was unambiguously confirmed by single-crystal X ray diffraction. Their pesticidal activities were evaluated against three serious and typically crop-threatening agricultural pests, Tetranychus cinnabarinus Boisduval (spider mite), Mythimna separata Walker (Oriental armyworm), and Plutella xylostella Linnaeus (diamondback moth). Compounds VIIIb and VIIIc exhibited greater than 40-fold more potent acaricidal activity than the lead compound piperine against T. cinnabarinus. Notably, compounds VIa-c exhibited more pronounced oral toxicity against P. xylostella than toosendanin; compounds VIb and VIc displayed more promising growth inhibitory activity against M. separata than toosendanin. It demonstrated that the methylenedioxy and isoxazoline scaffolds were important for the oral toxicity and growth inhibitory activity against P. xylostella and M. separata, respectively; the ethylenedioxy and isoxazoline scaffolds were vital for the acaricidal activity against T. cinnabarinus. Moreover, compounds VIb, VIIf, and VIIIc showed very low toxicity against NRK-52E cells. PMID- 30295026 TI - Propensity for Proton Relay and Electrostatic Impact of Protein Reorganization in Slr1694 BLUF Photoreceptor. AB - Photoreceptor proteins play a vital role in a wide range of light-regulated processes. The formation of the light-adapted state of blue light using flavin (BLUF) photoreceptors is thought to involve rearrangements of hydrogen-bonding networks upon photoexcitation. Free energy simulations with partial charges corresponding to relevant ground and excited states of the Slr1694 BLUF domain characterize conformations prior to and following photoexcitation. The simulations indicate that Trp91 is thermodynamically favored to be in the active site, although it is also able to sample conformations outside the active site. For experimentally observed conformations of Trp91, Gln50 is thermodynamically favored to be oriented for a proton relay bridging Tyr8 and the flavin. When Trp91 is rotated such that it can donate a hydrogen bond to Gln50, as observed in other BLUF domains, the proton relay is not thermodynamically favored in the ground state, providing a possible explanation for the relatively fast photocycle of the Slr1694 BLUF domain. Photoexcitation to the locally excited (LE) state of the flavin induces the formation of the proton relay if it is not already formed. Electrostatically embedded time-dependent density functional theory calculations indicate that the proton relay reduces the energy gap between the LE state and the charge-transfer (CT) state associated with electron transfer from Tyr8 to the flavin. Although the CT state is higher in energy than the LE state prior to photoexcitation, the protein environment can reorganize in a manner that stabilizes the CT state so that it is lower than the LE state, enabling the LE to CT state transition. An electrostatic analysis identifies motions of individual residues, such as Arg65, that stabilize electron transfer from Tyr8 to the flavin. These conformational changes facilitate the critical proton-coupled electron transfer reaction in the BLUF photocycle. PMID- 30295027 TI - Nitrogen-Doped Microporous Carbons Derived from Pyridine Ligand-Based Metal Organic Complexes as High-Performance SO2 Adsorption Sorbents. AB - Heteroatom-doped porous carbons are emerging as platforms for gas adsorption. Herein, N-doped microporous carbon (NPC) materials have been synthesized by carbonization of two pyridine ligand-based metal-organic complexes (MOCs) at high temperatures (800, 900, 1000, and 1100 degrees C). For NPCs (termed NPC-1- T and NPC-2- T, where T represents the carbonization temperature), the micropore is dominant, pyridinic-N and other N atoms of MOC precursors are mostly retained, and the N content reaches as high as 16.61%. They all show high Brunauer-Emmett Teller surface area and pore volume, in particular, NPC-1-900 exhibits the highest surface areas and pore volumes, up to 1656.2 m2 g-1 and 1.29 cm3 g-1, respectively, a high content of pyridinic-N (7.3%), and a considerable amount of SO2 capture (118.1 mg g-1). Theoretical calculation (int = ultrafine m062x) indicates that pyridinic-N acts as the leading active sites contributing to high SO2 adsorption and that the higher content of pyridinic-N doping into the graphite carbon layer structure could change the electrostatic surface potential, as well as the local electronic density, which enhanced SO2 absorption on carbon edge positions. The results show great potential for the preparation of microporous carbon materials from pyridine ligand-based MOCs for effective SO2 adsorption. PMID- 30295028 TI - Light-Induced Printing of Protein Structures on Membranes in Vitro. AB - Reconstituting functional modules of biological systems in vitro is an important yet challenging goal of bottom-up synthetic biology, in particular with respect to their precise spatiotemporal regulation. One of the most desirable external control parameters for the engineering of biological systems is visible light, owing to its specificity and ease of defined application in space and time. Here we engineered the PhyB-PIF6 system to spatiotemporally target proteins by light onto model membranes and thus sequentially guide protein pattern formation and structural assembly in vitro from the bottom up. We show that complex micrometer sized protein patterns can be printed on time scales of seconds, and the pattern density can be precisely controlled by protein concentration, laser power, and activation time. Moreover, when printing self-assembling proteins such as the bacterial cytoskeleton protein FtsZ, the targeted assembly into filaments and large-scale structures such as artificial rings can be accomplished. Thus, light mediated sequential protein assembly in cell-free systems represents a promising approach to hierarchically building up the next level of complexity toward a minimal cell.

We here report on two new scaffolds along with their photoreactivity in solution. Through use of selected external oxidants, the photogeneration of hydride donors is monitored using UV-visible, NMR, and TEM methods. As a proof-of-concept, photogeneration of hydride in the presence of Ag+ gave rise to the formation of Ag nanoparticles. PMID- 30295029 TI - Structural Studies of Amyloid Fibrils by Paramagnetic Solid-State Nuclear Magnetic Resonance Spectroscopy. AB - Application of paramagnetic solid-state NMR to amyloids is demonstrated, using Y145Stop human prion protein modified with nitroxide spin-label or EDTA-Cu2+ tags as a model. By using sample preparation protocols based on seeding with preformed fibrils, we show that paramagnetic protein analogs can be induced into adopting the wild-type amyloid structure. Measurements of residue-specific intramolecular and intermolecular paramagnetic relaxation enhancements enable determination of protein fold within the fibril core and protofilament assembly. These methods are expected to be widely applicable to other amyloids and protein assemblies. PMID- 30295031 TI - Characterizing Novel Modifications of a Therapeutic Protein Using Ultra Performance Liquid Chromatography-Tandem Mass Spectrometry, Sedimentation Velocity Analytical Ultracentrifugation, and Structural Modeling. AB - Heterogeneity of biopharmaceutical products is common due to various co- and post translational modifications and degradation events that occur during the biological production process and throughout the shelf life. Product-related variants resulting from these modifications potentially affect a product's biological activity and safety, and thus, their detailed structure characterization is of great importance for successful development of protein therapeutics. Specifically, in this study, two novel low-level product variants in a recombinant therapeutic protein were characterized via chromatographic enrichment followed by proteolytic digestion and analysis using ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). One of the variants was identified to be the therapeutic protein missing a 61-amino-acid fragment from its N-terminus. Consequently, the other variant was found to be the therapeutic protein carrying the 61-amino-acid long peptide. Furthermore, detailed structure at the modification site of the latter variant was determined as that amino group from the protein's N-terminus linked to side chain carbonyl carbon at Asp 61 residue of the peptide, based on the complementary information from collision induced dissociation and electron transfer dissociation MS/MS analysis. Results from sedimentation velocity analytical ultracentrifugation and computational structural modeling supported the hypothesis that formation of these two variants was a result of protein self-association. In dimeric state, the head-to-toe stacking conformation of two therapeutic protein molecules allowed spatial closeness between the N-terminus of one molecule and the 61st amino acid of the other molecule, resulting in a novel peptide transfer between the two protein molecules. PMID- 30295032 TI - ProteomeGenerator: A Framework for Comprehensive Proteomics Based on de Novo Transcriptome Assembly and High-Accuracy Peptide Mass Spectral Matching. AB - Modern mass spectrometry now permits genome-scale and quantitative measurements of biological proteomes. However, analysis of specific specimens is currently hindered by the incomplete representation of biological variability of protein sequences in canonical reference proteomes and the technical demands for their construction. Here, we report ProteomeGenerator, a framework for de novo and reference-assisted proteogenomic database construction and analysis based on sample-specific transcriptome sequencing and high-accuracy mass spectrometry proteomics. This enables the assembly of proteomes encoded by actively transcribed genes, including sample-specific protein isoforms resulting from non canonical mRNA transcription, splicing, or editing. To improve the accuracy of protein isoform identification in non-canonical proteomes, ProteomeGenerator relies on statistical target-decoy database matching calibrated using sample specific controls. Its current implementation includes automatic integration with MaxQuant mass spectrometry proteomics algorithms. We applied this method for the proteogenomic analysis of splicing factor SRSF2 mutant leukemia cells, demonstrating high-confidence identification of non-canonical protein isoforms arising from alternative transcriptional start sites, intron retention, and cryptic exon splicing as well as improved accuracy of genome-scale proteome discovery. Additionally, we report proteogenomic performance metrics for current state-of-the-art implementations of SEQUEST HT, MaxQuant, Byonic, and PEAKS mass spectral analysis algorithms. Finally, ProteomeGenerator is implemented as a Snakemake workflow within a Singularity container for one-step installation in diverse computing environments, thereby enabling open, scalable, and facile discovery of sample-specific, non-canonical, and neomorphic biological proteomes. PMID- 30295033 TI - Egg White-Derived Tripeptide IRW (Ile-Arg-Trp) Is an Activator of Angiotensin Converting Enzyme 2. AB - Angiotensin converting enzyme 2 (ACE2) plays beneficial roles in the renin angiotensin aldosterone system. Our previous studies indicated that egg white derived antihypertensive peptide IRW (Ile-Arg-Trp) could upregulate ACE2 mRNA level in mesenteric artery of spontaneously hypertensive rats (SHRs), suggesting the potential of IRW as an in vivo ACE2 activator. In this study, the effects of IRW on activity and protein expression of ACE2 were investigated. Results indicated that IRW activated human recombinant ACE2 with an EC50 value of 7.24 * 10-5 M. In rat aortic vascular smooth muscle cell line A7r5 cells, IRW treatment (50 MUM) significantly increased the expression and activity of ACE2. Oral administration of IRW to SHRs upregulated ACE2 protein levels in kidney and aorta. Molecular docking study suggested that IRW might activate ACE2 through interaction with the subdomain I near the active site through hydrogen bonds. Overall, this study established IRW as the first food-derived ACE2 activating peptide. PMID- 30295034 TI - Intact Human Alpha-Acid Glycoprotein Analyzed by ESI-qTOF-MS: Simultaneous Determination of the Glycan Composition of Multiple Glycosylation Sites. AB - Alpha-1-acid glycoprotein (AGP) is a highly glycosylated protein from human plasma with five N-type glycosylation sites carrying dominantly higher antennary structures and thus represents a challenging target for characterization of glycan heterogeneity. Here, we show that glycan composition over all five glycosylation sites can be determined quantitatively by ESI-qTOF-MS of the intact glycoprotein in negative ion mode. We find numerous glycan species extending the mass range of the glycoprotein species from 35.0 to 38.5 kDa. The dominant glycan compositions contain tri- and tetraantennary structures on all glycosylation sites. The mass degeneracy of two fucosyl units versus one sialic acid was resolved by treating the sample with sialidase and analyzing the resulting desialylated AGP by electrospray ionization-mass spectrometry in positive ion mode. The pattern of nonsialylated oligosaccharides was used for interpretation of the fully sialylated species using bioinformatics tools. From pooled human plasma, we find 90, 101, and 64 different glycan compositions for genetic variants ORM1*F1, ORM1*S, and ORM2, respectively. Glycan structures carry dominantly between 15 and 16 sialic acids indicating an almost complete termination of all antenae with sialic acid. AGP from human plasma samples of single individuals was analyzed as desialylated glycoproteins and showed variations in fucosylation and in the amount of antennary structures between individuals.

AB - The evolution of the nanobubble from gas molecules in liquid phase is of fundamental interest. However, the lack of sensitive tools hinders the study of growth dynamic of the bubble at nanoscale. Here, we employed a confined glass nanopore to real-time monitor the dynamics behavior of a single nanobubble generated by the reaction between NaBH4 and H2O. By analyzing the characteristic ionic current signal, the formation time and growth time of a single nanobubble could be estimated as 200 and 21 ms, respectively. Further, the nanopore size has been altered to modulate the growth behavior of the nanobubble. The results demonstrate the capability of the nanopore for sensitively tracking the behavior of single nanobubbles in liquid phase, which provides a powerful method for further understanding nanobubble evolution. PMID- 30295036 TI - Formation of Phenolic Compounds from d-Galacturonic Acid. AB - Aqueous d-galacturonic acid (d-GalA) model systems treated at 130 degrees C at different pH values show an intense color formation, whereas other reducing sugars, such as d-galactose (d-Gal), scarcely react. GC-MS measurements revealed the presence of several phenolic compounds: e.g., 3,8-dihydroxy-2-methyl-4 H chromen-4-one (chromone) and 2,3-dihydroxybenzaldehyde (2,3-DHBA). These phenolic compounds, especially 2,3-DHBA, possess an intense browning potential and cannot be found within heated model solutions of reducing sugars. Investigations regarding the formation of these substances show that alpha-ketoglutaraldehyde plays an important role as an intermediate product. In addition, MS analysis of model systems of norfuraneol in combination with 2,3-DHBA showed the formation of oligomers that could also be detected in d-GalA model systems, leading to the assumption that, in addition to reductic acid, these compounds are jointly responsible for the strong color formation during the heat treatment of d-GalA.

PARTICIPANTS: Twenty-two residents with mild-to-severe dementia. MEASUREMENTS: Dementia severity and QOL were assessed using the MMSE and Greater Cincinnati Chapter Well-Being Observational Tool. Resident-caregiver interactions were analyzed using a modified version of the Quality of Interactions Schedule. Semistructured interviews were conducted upon the study's conclusion. RESULTS: Quantitatively, participants initially classified with mild-moderate dementia were significantly more likely to experience positive benefits compared to those initially classified with severe dementia. There were no significant changes in dementia severity over time. There was also no change in QOL or resident caregiver relationships for those with mild-moderate dementia over time, although there was a decrease in certain measures of QOL and resident-caregiver relationships for those with severe dementia. Qualitative analysis identified consistent benefits for residents with both mild-moderate and severe dementia over time. CONCLUSIONS: Mixed-methods analyses helped identify benefits of TimeSlips for persons at all levels of dementia severity, but particularly for those with milder dementia. Such an observation helps demonstrate how arts-based programs like TimeSlips can uniquely benefit people with advanced memory impairments and thereby support QOL. PMID- 30295038 TI - The Role of Gender in Shame, Hostility, and Aggression Experienced by Caregivers for Patients With Dementia. AB - The aim of this study was to investigate the differences between male and female caregivers for patients with dementia in the way they experience various psychosocial parameters such as shame, hostility, and aggression. The sample included 55 caregivers of patients with moderate and severe dementia, whereas the average age was 51 years. Female caregivers were found to experience significantly higher levels of external shame, measured by Other As Shamer scale, than male caregivers, t (53) = 2.54, P < .01. A significant difference was also found between the female and male caregivers regarding their recorded levels of internal shame, measured by Experience of Shame Scale, with female caregivers experiencing more internal shame than their male counterparts, t (53) = 2.11, P < .01. However, no significant differences were found in hostility and aggression between males and females. These results demonstrate the existence of gender differences in the levels of shame experienced by care providers for patients with dementia.

AB - PURPOSE: To evaluate the bactericidal activity of a diluted povidone-iodine formulation (0.6%) in comparison with the most used 5% povidone-iodine solution ophthalmic preparation. METHODS: In vitro bactericidal activity comparison between 0.6% povidone-iodine versus 5% povidone-iodine formulations, against these bacteria: Staphylococcus aureus ATCC 25923, Staphylococcus aureus ATCC 43300, Staphylococcus epidermidis ATCC 12228, linezolid-resistant Staphylococcus epidermidis alpha99 strain, a clinical isolate, Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922. RESULTS: About 0.6% povidone-iodine formulation was demonstrated to be faster than 5% povidone-iodine preparation in killing Gram-positive as well as Gram-negative bacteria. Against a linezolid resistant methicillin-resistant Staphylococcus epidermidis strain, 0.6% povidone iodine formulation showed the best antiseptic efficacy requirement of 3-log10 reduction in bacterial load, if compared with the 5% povidone-iodine formulation. CONCLUSION: Our investigation has demonstrated that the more diluted 0.6% preparation was more rapidly bactericidal than the 5% povidone-iodine formulation, most probably due to the fact that dilution from 5% to 0.6% increases the amount of free iodine. While our finding must be confirmed by in vivo clinical studies, this fact constitutes an intriguing news for what concerns the use of povidone-iodine eye drops in the ocular surface treatment before intravitreal injections as well as ophthalmic surgery.

AB - The human lifespan in the developed countries significantly increased, from about 40 years to 80 years, in the last hundred years. This change is due to multiple factors, however, the development of medicine and pharmacological research as well as social well-being and social care are primarily important. For aging, the attrition of the parts of the whole organism are responsible, which is caused by endogenous oxidation processes (free radicals), which can destroy any cells in the organism. The injury of the defense or regulatory organ systems (immune system, neuroendocrine system) influences the whole organism, causing its decline (aging), later complete loss of abilities (death). The organism has built-in mechanisms for defence (e.g., antioxidant enzymes), however, their functions are not enough in our modern, chemically seriously contaminated age and further support is needed. This support is represented by antioxidants, as vitamins A, C, and E, resveratrol, and pharmaceuticals as rapamycine and rapalogs, selegiline, metformin etc., which have important roles in the increase of lifespan and health span. The early start of treatments and the use of pharmaceutical combinations seem to be important. The paper introduces our today's' lifespan prolongers and discusses their effects as well as points to the ways of future development. Orv Hetil. 2018; 159(41): 1655-1663. PMID- 30295043 TI - [Modern treatment of metastatic hormone-sensitive prostate cancer]. AB - The treatment of metastatic prostate cancer can be divided into two pathophysiological phases: hormone-sensitive and castration-resistant phases. Huggins' observation in the year 1941, which was awarded with the Nobel Prize in 1966, has a key role in treatment during the hormone-sensitive phase, stating that if the testicles are removed, the size of the prostate cancer decreases. Inducing androgen deprivation, i.e., testosterone depletion is the basic treatment of metastatic prostate cancer that patients have to receive life-long. In the past eight years, five new agents have been approved besides docetaxel in the treatment of metastatic castration-resistant prostate cancer: sipuleucel-T, cabazitaxel, abiraterone, enzalutamide, and radium-223. With the sequential application of these agents, significant improvement can be achieved in survival. Besides the latest developments, the hormone-sensitive phase has become the focus of attention, especially in the treatment of patients with de novo metastases and poor prognosis. Many studies have proven the outstanding efficacy of adding early docetaxel and abiraterone to androgen deprivation therapy. The authors give a detailed overview of clinical studies leading to a paradigm change in treatment during the hormone-sensitive phase, and call attention to the difficulties encountered in Hungarian practice.

AB - During the rehabilitation of hearing-impaired patients, the preservation of residual acoustic hearing following cochlear implantation by minimizing the implantation trauma allows for improved hearing performance. To achieve this, minimally invasive, soft surgery methods and thinner, atraumatic electrodes were required. In our present study, we reported a case where Cochlear(r) Nucleus CI532 Slim Modiolar electrode was implanted in a patient with residual hearing. Our aim was to study the possible preservation of postoperative acoustic residual hearing by audiological monitoring. Since childhood, due to her congenital hearing loss, she has been wearing a conventional, airborne hearing correction device on both ears. Six months before cochlear implantation, we measured the progression on both sides of the hearing loss, so we decided to perform cochlear implantation. The patient had residual hearing on both ears prior to surgery thus the Cochlear(r) Nucleus CI532 Slim Modiolar Implant was used. The minimally invasive surgery was performed on the patient's right ear through the round window approach. Compared to the preoperative hearing threshold (average 85 dBHL) in the 4th postoperative week, an initial hearing threshold progression of 20-25 dBHL was observed between 0.25 and 1.0 kHz, while of 5-10 dBHL between 2.0-4.0 kHz. Hearing threshold measured in the 6th month showed a slight progression in the range above 1 kHz, but improved by the 12th month, to the results achieved at the 4th week. The effects of cochlear implantation on residual hearing have been studied in numerous studies, in which several key surgical and technical factors have been identified. Nucleus CI532 is a Slim Modiolar electrode profile that is close to the modiolus, so it is expected to have a lower endocochlear hydrodynamic load since it lies in the covering of the osseus spiral lamina, thus less influencing the dynamics of the basilar membrane. However, the perimodiolar location of the electrode array allows the adjacent nerve elements of the spiral ganglion to be stimulated with a lower electrical intensity and a reduced surface that may be neuroprotective. Preservation of acoustic residual hearing following cochlear implantation improves the patient's speech perception and the sound localization skills, particularly in difficult circumstances. Long-term residual hearing preservation may also be of great importance in the subsequent feasibility for regenerative procedures and drug treatments. Orv Hetil. 2018; 159(41): 1680-1688.

AB - INTRODUCTION: Owing to the rapid progress of the medical science and technology, the chances of survival of the extremely low birth weight (<1000 g) preterm babies have dramatically improved. Nevertheless, the research findings on their long-term developmental outcome are inconsistent. AIM: Our study has attempted to contribute to the understanding of the developmental mechanisms in the extremely low birth weight preterm infants and to the prediction of the developmental outcomes taking into account of the risk factors of development. METHOD: 34 preterm children who were free of any major central nervous system injury were followed up from one to 5-6 years of age. The psychomotor development of the infants was assessed at 1 and 2 years of age and, at 5-6 years of age, intelligence tests were administered to the children. Perinatal and environmental factors were included in the data analysis. RESULTS: The extremely low birth weight preterm children as a group displayed no developmental delay at any of the measurement points. The mean developmental quotients were 98.6 and 106.6 at ages 1 and 2 years, respectively. At 5-6 years of age, the mean verbal IQ was 101.4, while the mean performance IQ was 92.9. Behind the group means there was a wide range of individual variations. The most powerful contributors to the developmental outcomes were birth weight, bronchopulmonary dysplasia, intra uterine growth retardation, gender, and maternal education. The girls had a significant advantage over the boys in language development. Verbal intelligence was hampered by intracranial hemorrhage, while intrauterine growth restriction had a similar effect on the performance IQ. CONCLUSIONS: Our results suggest that even the extremely preterm infants may have rather good chances of satisfactory mental development. However, the individual developmental prospects are influenced by a great number of domain-specific risk- and protective factors. Although at a group-level, infant psychomotor development is a significant predictor of later intelligence quotient, the rate of development may change at any age. The phenomenon of "moving risk" underscores the importance of the long term follow-up of preterm infants. Orv Hetil. 2018; 159(41): 1672-1679. PMID- 30295048 TI - Burnout, perceived stress, and empathic concern: differences in female and male Millennial medical students. AB - The 'Millennial' generation faces medical education learning environment challenges differently. We explore gender differences in burnout, perceived stress, and empathic concern in third-year medical students. A sample size of 654 third-year medical students completed an annual survey over 6 years. Survey items included: the Maslach Burnout Inventory-Student Scale (MBI-SS), Interpersonal Reactivity Index (IRI), and Perceived Stress Scale (PSS). We examined demographic differences using independent sample t-tests and performed a two-way ANOVA to test for potential interactions. Female students were more likely to have higher empathic concern compared to male students (IRI) (20.9+/-3.9 versus 19.1+/-4.1, p<0.001), and reported more personal distress (IRI) (9.0+/-4.4 versus 7.6+/-3.8, p<0.001), emotional exhaustion (MBI-SS) (15.6+/-5.9 versus 14.4+/-5.9, P<0.013), and perceived stress (PSS) (17.3+/-6.1 versus 15.2+/-6.7, p<0.001). Male students were more likely to have cynicism (MBI-SS) and lower professional efficacy (MBI SS) scores. Results of multivariate analyses yielded no significant interactions between gender, age, and ethnicity. Self-reported experiences of burnout and stress differed in male and female third-year medical students. Burnout and perceived stress scores while statistically significant were small. These findings suggest that support services should be made broadly available to all medical students, but should be targeted to the specific needs of male and female students. PMID- 30295047 TI - Perceived Behavioral Control as a Key to Integrative Medicine. AB - The purpose of the present study was to identify the factors that are the strongest predictors of intentions and use of integrative medicine approaches in clinical practice. Ajzen's theory of planned behavior was used to guide our examination of these questions. Health care professionals exposed to a Veterans Health Administration program (N = 288) who completed survey instruments prior to and immediately after the program and 3 months later were the participants for this study. Findings suggest that the theory of planned behavior performs reasonably well in explaining our data showing the integration of integrative medicine approaches into clinical practice. We found that self-efficacy to use integrative health approaches and perceived preparedness to discuss nonpharmaceutical approaches with patients were the strongest predictors of intentions to use integrative health approaches and self-reported change in clinical practice. The implications of these findings are discussed. PMID- 30295049 TI - Use of two long-acting injectable antipsychotics for treatment-resistant schizophrenia.

AB - BACKGROUND/AIMS:: An increasing body of research is being conducted with non English-speaking subjects. Study-related materials, including those essential for obtaining informed consent, must often be translated from English into other languages. In this study, we sought to examine the types of issues that may arise when consent materials are translated from English to Spanish. METHODS:: Drawing on expertise from five individuals associated with our research team, four of whom are native Spanish speakers of different dialects of Spanish, we crafted translations of our own consent materials for biobanking using a rigorous, multi step process involving both forward and back translation. We then systematically compared our translations to those produced by four professional translation firms to identify potential concerns in our own and the professional translations. RESULTS:: We identified three primary types of problems of relevance for researchers conducting studies where translation of written information is required. These included nonequivalent registers (in particular, the introduction of more complicated language), errors of omission (reducing the clarity of the information), and changes that altered the substantive meaning of the information. CONCLUSION:: Our findings highlight the importance of working with translators who not only possess "textbook" knowledge of both languages but also an appreciation of the sociocultural factors that affect how people interpret and understand meaning. Moreover, translators who have a basic understanding of research are more likely to accurately convey essential research concepts. We describe a series of steps researchers can take that may help to improve the quality of translated materials.

AB - AIM: A rapid and reliable method of discriminating such specimens would be very useful. MATERIALS & METHODS: We analyzed 566 urine specimens from patients with suspected urinary tract infections using a fully automated urine particle analyzer (UF-5000) and evaluated its performance for culture-negative urine specimens. RESULTS: Using the algorithm cutoff values of bacteria less than 30/MUl and/or white blood cell less than 200/MUl, we obtained a sensitivity of 97.8%, a specificity of 74.6%, a positive predictive value of 46.9%, a negative predictive value of 99.3%, an agreement of 78.9% with the culture method and reduced 61% unnecessary urine culture. Regarding the discrimination of bacterial Gram groups, 67.7% (63/93) of cases were correctly analyzed using the UF-5000 bacteria information, with a Cohen's kappa concordance coefficient of 0.775 (chi2 = 31.65, p < 0.001). CONCLUSION: The performance of UF-5000 for rapidly discriminating culture-negative specimens was quite acceptable for clinical use. PMID- 30295054 TI - Psychometric Properties of the Dutch Strengths and Difficulties Questionnaire (SDQ) in Adolescent Community and Clinical Populations. AB - This study assessed the factor structures of the Strengths and Difficulties Questionnaire (SDQ) adolescent and parent versions and their measurement invariance across settings in clinical ( n = 4,053) and community ( n = 962) samples of Dutch adolescents aged 12 to 17 years. Per SDQ version, confirmatory factor analyses were performed to assess its factor structure in clinical and community settings and to test for measurement invariance across these settings. The results suggest measurement invariance of the presumed five-factor structure for the parent version and a six-factor structure for the adolescent version. Furthermore, evaluation of the SDQ scale sum scores as used in practice, indicated that working with sum scores yields a fairly reasonable approximation of working with the favorable but less easily computed factor scores. These findings suggest that adolescent- and parent-reported SDQ scores can be interpreted using community-based norm scores, regardless of whether the adolescent has been referred for mental health problems. PMID- 30295055 TI - A Reformulated Architecture of Cognitive Risks for Psychopathology: Common and Specific Dimensions and Links to Internalizing Outcomes in Adolescence. AB - Multiple cognitive risk products (dysfunctional attitudes [DA], negative inferential style [NIS], self-criticism, dependency, rumination) predict internalizing disorders; however, an optimal structure to assess these risks is unknown. We evaluated the fit, construct validity, and utility of a bifactor, single, and correlated factor model in a community sample of 382 adolescents (age 11-15 years; 59% female). The bifactor, hierarchical single, and correlated factor models all fit well. The bifactor model included a common factor ( c), capturing covariance across all cognitive risk measures, and specific latent factors for DA, NIS, dependency and rumination. Construct validity of these factor structures was evaluated with external validators, including depression and anxious arousal (AA) symptoms, positive affect (PA) and negative affect (NA), and onset of depression diagnostic onset over 2 years. C was associated with higher depression, NA, and AA; lower PA; and predicted depressive episodes. Hierarchical single and correlated factor models also related to external validators.

AB - We aimed to compare salient characteristics and antecedents of quality of life (QOL) in adolescents and young adults with implantable cardioverter defibrillators (ICDs) from qualitative methods with quantitative measurement of QOL and correlations between QOL (PedsQL) and measured participant characteristics. Concurrent parallel mixed methods design was used to collect survey data from the PedsQL electronic health record, demographic questionnaire, and semistructured interview data. A convenience sample of 16 individuals with ICDs, aged 13 to 25 years, was obtained from a tertiary pediatric facility. Overall QOL and subdomains of physical, psychosocial, and academic/work were examined by PedsQL and visual analog scale. Select demographics were collected to develop a participant profile. Females with ICDs appear to be at risk of poor QOL given some unknown factors. Financial status of the individual and the family was positively related to QOL. For new ICD persons involved in physical activities that must be stopped, peer support appears to improve QOL.

AB - This study used the correlated trait-correlated method minus one model to examine the convergent and discriminant validity of the scales of the Conners 3 Short [C 3 (S)]. The C 3 (S) scales in the analysis were inattention (IN), hyperactivity/impulsivity (HY), learning problems (LP; learning problems/executive functioning from the teacher version), aggression (AG), and peer relations (PR, only for parent and teacher versions). A total of 529 adolescents and children (75% males, mean age = 11.75 years, SD = 2.97 years) provided self-ratings, and were also rated by their mothers and teachers. The findings indicated no support for the convergence of IN and HY across the three respondents. In contrast, there was convergence for LP, AG, and PR. There was support for the discriminant validity of the traits, except between IN and HY. The findings are discussed in relation to the convergent and discriminant validity of the C 3 (S) measures, and the clinical use of the C 3 (S). PMID- 30295059 TI - Study of lamina cribrosa depth and optic nerve in patients with spontaneous intracranial hypotension. AB - PURPOSE: The aim of this study is to analyze the lamina cribrosa depth and to study the optic nerve in patients with spontaneous intracranial hypotension. METHODS: A total of 10 eyes of the patients with spontaneous intracranial hypotension with unknown etiology (study group) and 10 eyes of healthy patients without any ophthalmological or neurological pathologies (control group) were included. The subjects were submitted to ophthalmological examination with the evaluation of visual acuity, spherical equivalent, applanation tonometry, pachymetry, axial length, retinography, computerized static perimetry (Humphrey 30-2 SITA-Standard), and OCT Spectralis with enhanced depth image, to calculate the depth of the anterior surface of the lamina cribrosa and to measure the nerve fiber layer thickness of the optic nerve. All of these parameters were compared between the two groups. RESULTS: Mean anterior surface of the lamina cribrosa depth was 447.96 +/- 118.51 (313.30-632.0) MUm for the spontaneous intracranial hypotension group and 292.56 +/- 40.71 (247-387) MUm for the control group, with a statistically significant difference between them (p = 0.001). The thickness of the nerve fiber layer did not differ significantly in the temporal (p = 0.94), nasal (p = 0.173), superior (p = 0.41), central (p = 0.36) or inferior (p = 0.5) sectors. Four eyes of patients with spontaneous intracranial hypotension showed a marked reduction in the temporal nerve fiber layer. Pachymetry (p = 0.16), axial length (p = 0.71), and intraocular pressure (p = 0.6) did not differ significantly between groups, whereas spherical equivalent (p = 0.03) was significantly different. Visual fields were normal in both groups. CONCLUSION: The translaminar gradient is determinant in the structure of the lamina cribrosa. Low intracranial pressure associated with a high translaminar gradient leads to an increased lamina cribrosa depth similar to that observed in glaucoma patients.

AB - Care plans can reduce care fragmentation for children with medical complexity (CMC); however, implementation is challenging. Mobile health innovations could improve implementation. This mixed methods study's objectives were to (1) evaluate feasibility of mobile complex care plans (MCCPs) for CMC enrolled in a complex care program and (2) study MCCPs' impact on parent engagement, parent experience, and care coordination. MCCPs were individualized, updated quarterly, integrated within the electronic health record, and visible on parents' mobile devices via an online portal. In 1 year (September 1, 2016, to August 31, 2017), 94% of eligible patients (n = 47) received 162 MCCPs. Seventy-four percent of parents (n = 35) reviewed MCCPs online. Forty-six percent of these parents (n = 16) sent a follow-up message, and the care team responded within 8 hours (median time = 7.2 hours). In interviews, parents identified MCCPs as an important reference and communication tool. MCCPs for CMC in a complex care program were feasible, facilitated parental engagement, and delivered timely communication.

AB - A capsule-defective mutant strain PBA129 of Pasteurella multocida was constructed by electroporation of phagemid containing the coding region of the antisense RNA of the ompH gene into the wild type strain X-73 (serovar A:1) of P. multocida. The pathogenicity and protective potency of the mutant against homologous and heterologous challenge in mice and chickens were characterized. Greyish colonies of the mutant, indicating lower capsule thickness, on selective dextrose starch agar were observed under an obliquely transmitted light stereomicroscope and compared to iridescent colonies of the wild type strain X-73. Strain PBA129 had lower capsule thickness than the wild type strain as observed with an electron microscope. Strain PBA129 was apparently attenuated, as mice and chickens inoculated with the bacteria at 108 CFU survived. Protection was observed in both mice and chickens inoculated with strain PBA129 upon challenge exposure to avian P. multocida strains X-73 and P-1059 (serovar A:3), respectively. In conclusion, the mutant strain PBA129 of P. multocida strain X-73 was completely attenuated, and it was possible to induce sufficient protection against avian P. multocida strains. PMID- 30295062 TI - Risk of probable posttraumatic stress disorder in patients with trigeminal neuralgia. AB - The object of this study was to reveal the occurrence, risk factors and prognosis of posttraumatic stress disorder (PTSD) in patients with trigeminal neuralgia (TN). Adult patients who were diagnosed with TN were prospectively collected from our neuroscience center. Among the 103 patients recruited, thirty (29.1%) participants were identified as probable PTSD cases measured with PTSD Checklist for DSM-5 (PCL-5). Compared with patients without PTSD, patients with probable PTSD were more likely to be female, have severe pain intensity, be with severely interfered general activities, be with more intense depression and anxiety, and be more habitually using maladaptive coping strategies. Logistic regression analysis showed female sex, severe pain intensity, anxiety and depression predicted probable PTSD. In the 28 patients who were initially identified as probable PTSD and had 6-month follow-up data, 21 reported complete pain relief and 4 reported partial pain relief. Fifteen of the patients who experienced complete pain relief recovered from probable PTSD. Our work indicated that PTSD can develop among patients with TN. Complete pain relief through surgical treatments can help most patients with probable PTSD recover, however, psychological support is advised for those who are still obsessed by mental disorders even after pain relief. PMID- 30295063 TI - Comparison of two biometers: A swept-source optical coherence tomography and an optical low-coherence reflectometry biometer. AB - PURPOSE: The technological improvements in optical biometers have made cataract surgery evolve to the level of refractive surgery. This study assessed the correlation and agreement between a biometer using swept-source optical coherence tomography technology (IOLMaster 700; Carl Zeiss Meditec, Jena, Germany) and a biometer using optical low-coherence reflectometry (Lenstar; Haag Streit, Koeniz, Switzerland). PROCEDURES: Optical biometric measurements were taken with the IOLMaster 700 and the Lenstar on 129 eyes of 129 patients referred for cataract surgery. We compared biometric data (axial length, mean keratometry, central pachymetry, anterior chamber depth, lens thickness, and horizontal white-to-white measurement) and the emmetropic intraocular lens power calculated with SRK/T and Haigis formulas. Correlation and agreement for these parameters were evaluated. RESULTS: Only anterior chamber depth measurements (3.05 +/- 0.07 vs 3.07 +/- 0.07, p < 0.001) and the white-to-white measurement (11.97 +/- 0.07 vs 12.06 +/- 0.07, p < 0.001) differed significantly between the machines. Correlations and agreements were excellent, with perfect agreement for axial length measurement ( r = 1, intraclass correlation coefficient = 1). Emmetropic intraocular lens power did not differ between devices with SRK/T formula (20.94 +/- 0.51 vs 20.92 +/- 0.50, p = 0.51). With Haigis formula, there was a statistically significant difference (21.04 +/- 0.52 vs 20.84 +/- 0.52, p < 0.001). CONCLUSION: This study suggests that there is a very high correlation and agreement for the biometric measurements and calculation of intraocular lens implant power with the SRK/T formula.

AB - PURPOSE: Until Helmholtz's discovery of the ophthalmoscope, it was not possible to visualize the posterior pole of the eye in a living subject. The aim of this work is to emphasize the importance of the invention of the ophthalmoscope because the new era in ophthalmology began with it. METHODS: Available literature concerning this topic was studied, especially by getting in contact with institutes for history of medicine as well as medico-historians in Germany and other countries. RESULTS: Hermann von Helmholtz, German physician and physicist, presented and published his invention of the ophthalmoscope in 1851. Albrecht von Graefe was the first to use ophthalmoscope routinely. He said: 'Helmholtz has opened a new world to us'. The first ophthalmoscope was not easy to use. Some ophthalmologists even thought that ophthalmoscopy is harmful for the eye, particularly for a diseased eye. First, it was used in Germany (A von Graefe), Austria (E Jager), and Netherlands (FC Donders). In England, it was used only at Moorfields till 1855 (W Bowman). At the First International Congress of Ophthalmology in Brussels 1857, the importance of ophthalmoscopy was stressed. FC Donders said that every view with the ophthalmoscope into the living eye was a new discovery. Among retinal diseases, first were discovered pigment retinopathy (FC Donders) and retinal detachment (A Coccius) in 1853. CONCLUSION: Helmholtz inaugurated modern era in ophthalmology with his magnificant instrument which revolutionized the development of ophthalmology. Von Graefe popularized it. Because of the new findings, ophthalmology was definitely separated from surgery in the middle of 19th century. PMID- 30295066 TI - Comparing the Nonlinear Dynamic Acoustic Parameters of Healthy Adult and Pediatric Voices. AB - OBJECTIVES:: The aims of this study were to compare nondysphonic adult and pediatric voices using linear and nonlinear acoustic parameters and to evaluate the ability of adult spectrum convergence ratio (SCR) and rate of divergence (ROD) reference values to correctly identify a pediatric voice type as periodic or aperiodic. METHODS:: Twenty adult and 36 pediatric nondysphonic voice samples were collected and analyzed using linear and nonlinear acoustic parameters. Absence of voice disorder was confirmed using perceptual acoustic and spectral analysis. Mean values for jitter, shimmer, SCR, and ROD were compared between adults and children, across specific age groups, and within genders. Using adult reference values for SCR and ROD, samples were classified as primarily periodic or aperiodic and typed using spectral analysis. Rates of accurate typing were also compared between subject groups. RESULTS:: Overall, jitter and shimmer were similar among the adult and pediatric age groups. ROD was significantly different among the 3 pediatric and 1 adult group; the pediatric age groups were similar to one another. Adult SCR was also significantly different from all of the pediatric age groups. In adult men, ROD and SCR were significantly different from all of the pediatric age groups; the pediatric age groups were similar to one another. In female subjects, ROD was significantly different among all age groups. The ROD and SCR reference values were significantly better at categorizing adult voice types compared with pediatric voice types. CONCLUSIONS:: In healthy subjects, SCR and ROD have discriminatory power for identifying adult versus pediatric voices, while jitter and shimmer cannot differentiate between the 2 groups. However, age- and gender-specific pediatric reference values must be determined to accurately classify voice types using SCR and ROD. PMID- 30295067 TI - Effect of Preanalytic Variables on an Automated PTEN Immunohistochemistry Assay for Prostate Cancer. AB - CONTEXT.-: Phosphatase and tensin homolog (PTEN) is a promising prognostic and potentially predictive biomarker in prostate cancer. OBJECTIVE.-: To assess the effects of preanalytic variables on an analytically validated and fully automated PTEN immunohistochemistry assay. DESIGN.-: PTEN immunohistochemistry was performed on Ventana immunostaining systems. In benign prostate tissues, immunostaining intensity across variable conditions was assessed by digital image analysis. In prostate tumor tissues, immunostaining was scored visually. RESULTS. : Delay of fixation for 4 hours or longer at room temperature or 48 hours or longer at 4 degrees C and duration of formalin fixation did not significantly alter immunostaining intensity. Intensity of staining was highest in 10% formalin compared with other fixatives. Tumor tissues with PTEN loss processed using protocols from 11 academic institutions were all evaluable and scored identically. PTEN immunostaining of needle biopsies where tissue blocks had been stored for less than 10 years was more frequently scored as nonevaluable compared with blocks that had been stored for 10 years or longer. This effect was less evident for radical prostatectomy specimens, where low rates of nonevaluable staining were seen for 23 years or more of storage. Storage of unstained slides for 5 years at room temperature prior to immunostaining resulted in equivalent scoring compared with freshly cut slides. Machine-to-machine variability assessed across 3 Ventana platforms and 2 institutions was negligible in 12 tumors, and platform-to-platform variability was also minor comparing Ventana and Leica instruments across 77 tumors (kappa = 0.926). CONCLUSIONS.-: Automated PTEN immunostaining is robust to most preanalytic variables in the prostate and may be performed on prostate tumor tissues subjected to a wide range of preanalytic conditions. These data may help guide assay development if PTEN becomes a key predictive biomarker. PMID- 30295068 TI - Elimination of Autofluorescence in Archival Formaldehyde-Fixed, Paraffin-Embedded Bone Marrow Biopsies. AB - CONTEXT.-: High levels of autofluorescence in bone marrow tissue constitute a major obstacle to immunofluorescence analysis of bone marrow biopsies. OBJECTIVE. : To present a simple, efficient method to eliminate autofluorescence in bone marrow biopsies. DESIGN.-: Autofluorescence of paraffin bone marrow tissues was examined in different hematologic disorders with confocal laser scanning microscopy. Strong autofluorescence was observed in primary myelofibrosis and acute leukemia with reticulin myelofibrosis in 488-nm and 561-nm channels. To eliminate autofluorescence, AutoFluo Quencher was used on bone marrow sections with different incubation times. The effects of AutoFluo Quencher on immunofluorescence analysis of bone marrow biopsies was tested using antibodies tagged with different fluorophores. RESULTS.-: AutoFluo Quencher thoroughly eliminated the strong autofluorescence of bone marrow but did not decrease the intensity of fluorophores, leaving the specific signals of target proteins clearly visible. CONCLUSIONS.-: This study presents a simple, efficient method to eliminate autofluorescence in bone marrow paraffin tissue, and it opens the way to better results in the immunofluorescence analysis of bone marrow biopsies. PMID- 30295069 TI - Diagnostic Accuracy of Reflectance Confocal Microscopy Skin. AB - CONTEXT.-: Histopathology is the current standard to diagnose skin disease. However, biopsy may not always be feasible, such as in patients with multiple nevi, a patient with a lesion on an aesthetically significant site, or in children. Recently, noninvasive techniques, including reflectance confocal microscopy (RCM), optical coherence tomography, and Raman spectroscopy, have enabled dermatologists to manage skin lesions in real time without the need for biopsy. OBJECTIVE.-: To report the updated diagnostic accuracy of RCM for equivocal skin lesions. DESIGN.-: In this study, we retrospectively reviewed our data of clinically suspicious lesions from 2010 to 2017 that were evaluated by RCM. RESULTS.-: Our results showed an overall sensitivity of 98.2% and specificity of 99.8%. CONCLUSIONS.-: In conclusion, RCM is a noninvasive real time tool with the potential to diagnose skin lesions with high accuracy and without biopsy. PMID- 30295070 TI - Artificial Intelligence-Based Breast Cancer Nodal Metastasis Detection. AB - CONTEXT.-: Nodal metastasis of a primary tumor influences therapy decisions for a variety of cancers. Histologic identification of tumor cells in lymph nodes can be laborious and error-prone, especially for small tumor foci. OBJECTIVE.-: To evaluate the application and clinical implementation of a state-of-the-art deep learning-based artificial intelligence algorithm (LYmph Node Assistant or LYNA) for detection of metastatic breast cancer in sentinel lymph node biopsies. DESIGN.-: Whole slide images were obtained from hematoxylin-eosin-stained lymph nodes from 399 patients (publicly available Camelyon16 challenge dataset). LYNA was developed by using 270 slides and evaluated on the remaining 129 slides. We compared the findings to those obtained from an independent laboratory (108 slides from 20 patients/86 blocks) using a different scanner to measure reproducibility. RESULTS.-: LYNA achieved a slide-level area under the receiver operating characteristic (AUC) of 99% and a tumor-level sensitivity of 91% at 1 false positive per patient on the Camelyon16 evaluation dataset. We also identified 2 "normal" slides that contained micrometastases. When applied to our second dataset, LYNA achieved an AUC of 99.6%. LYNA was not affected by common histology artifacts such as overfixation, poor staining, and air bubbles. CONCLUSIONS.-: Artificial intelligence algorithms can exhaustively evaluate every tissue patch on a slide, achieving higher tumor-level sensitivity than, and comparable slide-level performance to, pathologists. These techniques may improve the pathologist's productivity and reduce the number of false negatives associated with morphologic detection of tumor cells. We provide a framework to aid practicing pathologists in assessing such algorithms for adoption into their workflow (akin to how a pathologist assesses immunohistochemistry results). PMID- 30295071 TI - Immune keratitis: An unusual primary presentation of neuro-Behcet's disease. AB - A 19-year-old Nepalese male presented with complaints of bilateral ocular discomfort, photophobia, watering, and redness for 1 week. Visual acuity was 6/12 and 6/60 in the right and left eye, respectively. On biomicroscopic examination, presence of peripheral stromal infiltrates with conjunctival follicles was noted; infiltrates progressed to involve central cornea with further decrease in vision over next few days. After ruling out infectious keratitis, detailed systemic examination and laboratory investigations were diagnostic of neuro-Behcet's disease. Patient responded to systemic steroidal and immunosuppressive therapy characterized by corneal healing and visual acuity improvement to 6/6 and 6/9. Although rare, but neuro-Behcet's disease can primarily present as bilateral immune keratitis and every case of bilateral keratitis needs early systemic evaluation after ruling out infective etiologies. PMID- 30295072 TI - Phytosterols in supplements containing Serenoa repens: an example of variability of active principles in commercial plant based products. AB - Phytosterols are one of the bioactive components responsible for the beneficial effects of Serenoa repens in Benign Prostate Hyperplasia. The aim of this study was to verify the actual variability of the phytosterols content in supplements containing serenoa, in order to provide useful elements to check the effectiveness of these preparations. The amount of campesterol, stigmasterol and beta-sitosterol were determined by gas-chromatography in commercial raw materials and supplements containing serenoa in association or not with other botanicals. The experimental data were used to calculate amounts of phytosterols for recommended daily dose. The overall results of this study show an extreme variability in the content and also in the amounts per daily dose of phytosterols of the examined supplements (both mono/multi components). These data confirm that the characterization of serenoa based supplements is insufficient to ensure comparable effects between different products. PMID- 30295073 TI - GC-EIMS analysis, antifungal and anti-aflatoxigenic activity of Capsicum chinense and Piper nigrum fruits and their bioactive compounds capsaicin and piperine upon Aspergillus parasiticus. AB - GC-EIMS analysis, antifungal- and anti-aflatoxigenic activities of the ethanolic extract of Capsicum chinense and Piper nigrum fruits and their main bioactive compounds were evaluated upon Aspergillus parasiticus. The GC-EIMS analysis showed capsaicin (50.49%) and piperine (95.94%) as the major constituents in C. chinense and P. nigrum, respectively. MIC50 values revealed that capsaicin (39 MUg/mL) and piperine (67 MUg/mL) were lower than those from fruit extracts of C. chinense (381 MUg/mL) and P. nigrum (68 MUg/mL). Extracts and bioactive compounds showed anti-aflatoxigenic activity. Maximum aflatoxin inhibition occurred at 150 ug/mL of extracts and compounds. The present study showed satisfactory results concerning the effects of ethanolic extract of C. chinense and P. nigrum fruits upon A. parasiticus, showing the capabilities of inhibiting fungal growth development and altering aflatoxins production. PMID- 30295074 TI - Treatment of chronic and extreme ocular hypotension following glaucoma surgery with intraocular platelet-rich plasma: A case report. AB - PURPOSE: To report a new approach for the treatment of severe ocular hypotony secondary to glaucoma filtering surgery with mitomycin C by injecting autologous eye platelet-rich plasma (E-PRP) in the anterior chamber to block excessive diffuse filtration through an abnormally thinned sclera. METHODS: A 49-year-old patient with the Axenfeld-Rieger syndrome and severe chronic hypotony and corneal edema following filtering glaucoma surgery with mitomycin C received an isolated injection of 0.3 mL of autologous platelet-rich plasma in the anterior chamber. RESULTS: Intraocular pressure measured by Goldman's applanation tonometry 6 h after the procedure improved to 18 mmHg. Intraocular pressure remained stable along the full follow-up period of 6 month. No filtration or hypotony or any other complications were observed. CONCLUSION: Intracameral platelet-rich plasma (E-PRP) injection was an effective, rapidly effective, and safe procedure for treatment of severe chronic ocular hypotony following glaucoma filtrating surgery. PMID- 30295075 TI - Progress of co-culture systems in cartilage regeneration. AB - INTRODUCTION: Cartilage tissue engineering has rapidly developed in recent decades, exhibiting promising potential to regenerate and repair cartilage. However, the origin of a large amount of a suitable seed cell source is the major bottleneck for the further clinical application of cartilage tissue engineering. The use of a monoculture of passaged chondrocytes or mesenchymal stem cells results in undesired outcomes, such as fibrocartilage formation and hypertrophy. In the last two decades, co-cultures of chondrocytes and a variety of mesenchymal stem cells have been intensively investigated in vitro and in vivo, shedding light on the perspective of co-culture in cartilage tissue engineering. Areas covered: We summarize the recent literature on the application of heterologous cell co-culture systems in cartilage tissue engineering and compare the differences between direct and indirect co-culture systems as well as discuss the underlying mechanisms. Expert opinion: Co-culture system is proven to address many issues encountered by monocultures in cartilage tissue engineering, including reducing the number of chondrocytes needed and alleviating the dedifferentiation of chondrocytes. With the further development and knowledge of biomaterials, cartilage tissue engineering that combines the co-culture system and advanced biomaterials is expected to solve the difficult problem regarding the regeneration of functional cartilage. PMID- 30295076 TI - Management of diabetic macular edema patients in clinical practice in Spain. AB - PURPOSE: Diabetic macular edema is the main cause of blindness in diabetic patients. Vascular endothelial growth factor is involved in diabetic macular edema pathogenesis. Vascular endothelial growth factor inhibitors are an important option in diabetic macular edema therapy. This survey investigates actual clinical practice in diabetic macular edema in Spain. METHODS: An expert advisory panel of 17 Spanish ophthalmologists developed a 30-item anonymous questionnaire about diagnosis, treatment, and follow-up in diabetic macular edema. A total of 137 ophthalmologists from 10 Spanish regions completed the questionnaire online. RESULTS: Almost all of the respondents (99.3%) record the measured visual acuity and perform biomicroscopic anterior (94.9%) and posterior (91.2%) segment examinations. Similarly, 100% of responding ophthalmologists always/almost always or frequently perform optical coherence tomography. Most respondents (65%) always/almost always or frequently perform a retinography. More than 50% rarely perform fluorescein angiography. Nearly, all (96.4%) of the specialists responded that, in center-involved diabetic macular edema, the first treatment is an anti-vascular endothelial growth factor drug. For corticosteroids, the first choice of most respondents (91.2%) was the dexamethasone implant. In the follow-up, almost all (96.4%) specialists record the measured visual acuity and most also perform biomicroscopic anterior (82.5%) and posterior (83.2%) segment examination. CONCLUSION: This survey shows the actual clinical practice in diabetic macular edema in Spain, finding that anti vascular endothelial growth factor therapy is frequently used, and that diagnosis, treatments, and follow-up examinations used by specialists are homogeneous and according to diabetic macular edema guidelines. PMID- 30295077 TI - Does anti-Mullerian hormone predict change in menopausal symptoms following risk reducing salpingo-oophorectomy? A prospective observational study. AB - OBJECTIVES: The aim of this study was to investigate whether serum anti-Mullerian hormone (AMH) predicts symptom burden after risk-reducing salpingo-oophorectomy (RRSO) in order to individualize counseling. METHODS: Patient-reported menopausal symptoms, sexual functioning, and psychological distress (depression and anxiety) were assessed 1 day before (T0) and 6 weeks (T1) and 7 months (T2) after RRSO. AMH was assessed before RRSO. Multivariable regression analysis was used to investigate the association between AMH and short-term and long-term change in symptom burden following RRSO. RESULTS: Ninety-one premenopausal women at high risk of ovarian cancer were included. Presurgical AMH was not related significantly to change in symptoms post RRSO. As a secondary outcome we found that regular menses before RRSO was associated specifically with long-term increase in hot flushes (sr = 0.40, p = 0.001; total R2 = 0.171) and depression (sr = 0.29, p = 0.012; total R2 = 0.132). Earlier receipt of chemotherapy was associated with long-term improvement in sexual functioning (sr = 0.24, p = 0.041; total R2 = 0.348). CONCLUSION: In this cohort, AMH was not a significant predictor of change in symptoms following RRSO. Regular menses prior to RRSO and earlier receipt of chemotherapy were significantly, but relatively weakly, associated with changes in outcomes 6 weeks and/or 7 months after RRSO. PMID- 30295078 TI - From enjoyment to physical activity or from physical activity to enjoyment? Longitudinal associations in parent-child dyads. AB - BACKGROUND: This longitudinal dyadic study used cross-lagged analyses to examine reciprocal patterns of associations between physical activity (PA) enjoyment and moderate-to-vigorous PA (MVPA) among children and their parents. METHODS: At Time 1 (T1) 879 parent-child dyads provided their data. The follow-up (Time 2, T2) took place 7-8-months later. MVPA and PA enjoyment scales were filled out separately by parents and children at T1 and T2. FINDINGS: Child PA enjoyment (T1) predicted a higher level of child MVPA (T2), parental PA enjoyment (T1) explained a higher level of parental MVPA (T2), and parental MVPA (T1) predicted a higher level of parental PA enjoyment (T2). Furthermore, child PA enjoyment (T1) predicted a higher level of parental PA enjoyment (T2). CONCLUSIONS: Child PA enjoyment was the key variable predicting child and parental outcomes. In particular, it explained child MVPA, but also PA enjoyment among parents. PMID- 30295080 TI - An unusual case of acoria in Sturge-Weber syndrome. AB - We present an unusual case of Sturge-Weber syndrome whose main clinical manifestations were nevus flammeus, seizures, glaucoma, and acoria. To our knowledge, the combination of Sturge-Weber syndrome and acoria has not been previously reported. PMID- 30295081 TI - Perceiving college peers' alcohol consumption: temporal patterns and individual differences in overestimation. AB - OBJECTIVE: This study examines temporal patterns and individual differences of overestimation in alcohol norm perception within a social network. DESIGN: Hundred psychology freshmen indicated biweekly during their first semester the drinks they consumed, the perceived average of their peers' consumption, and with whom they were acquainted. At baseline, trait self-control was assessed. MAIN OUTCOME: The moderation of alcohol consumption overestimation by time and individual characteristics was explored. RESULTS: Results show that students overestimated alcohol consumption of their acquainted peers by 1.22 drinks (p < .001). For time periods at which peers reported high consumption, overestimation decreased. Additionally, individuals reporting high alcohol consumption (b = 0.25, p < .001) and low self-control (b = 0.27, p = .010) showed higher overestimation. CONCLUSIONS: Students overestimate the alcohol consumption of peers not fully accounting for changes in peer-reports. Furthermore, individual differences suggest informational and motivational processes underlying overestimation. PMID- 30295079 TI - Prevention of Bortezomib-Related Peripheral Neuropathy With Docosahexaenoic Acid and alpha-Lipoic Acid in Patients With Multiple Myeloma: Preliminary Data. AB - BACKGROUND AND AIMS: Peripheral neuropathy is a common complication of chemotherapy that can induce marked disability that negatively affects the quality of life in patients with multiple myeloma (MM). The aim of this study was to prevent the onset or the worsening of peripheral neuropathy in MM patients treated with bortezomib (BTZ), using a new nutritional neuroprotective compound. We report preliminary results of 18 out of 33 patients who completed the study. METHODS: We administered a tablet of Neuronorm to patients, containing docosahexaenoic acid 400 mg, alpha-lipoic acid 600 mg, vitamin C 60 mg, and vitamin E 10 mg bid for the whole follow-up period. Neurological visit assessment, electroneurography, and evaluation scales were performed at baseline and after 6 months. RESULTS: At 6 months, 8 patients had no chemotherapy-induced peripheral neuropathy, while 10 patients experienced chemotherapy-induced peripheral neuropathy of grade 1 according to the Common Terminology Criteria for Adverse Events, one of them with pain. Seventeen patients did not report painful symptoms; no limitation of functional autonomy and stability in quality of life domains explored was observed. CONCLUSIONS: Our results seem to indicate that early introduction of a neuroprotective agent in our patients with MM treated with BTZ could prevent the onset or the worsening of neuropathic pain, avoiding the interruption of the therapy with BTZ, and maintaining a good functional autonomy to allow normal daily activities. Despite the limitations due to the fact that this is a preliminary study, in a small population, with short follow up, our data seem to indicate that the nutraceutical may have some potential to be considered for a future trial. PMID- 30295082 TI - Author's reply. PMID- 30295083 TI - SAR342434 - an insulin biosimilar for the treatment of type II diabetes. AB - INTRODUCTION: The global incidence of diabetes mellitus is increasing, with a concomitant rise in individual and overall treatment costs. The development of biosimilars contributes to the facilitation of greater access to treatment. SAR342434 is a biosimilar follow-on of insulin lispro, a key therapeutic for the treatment of diabetes mellitus, and it is currently under phase III clinical trials. Areas covered: In this review we discuss the recent updates on clinical data obtained from phase III trials to compare the equivalence and similarity of SAR342434 to insulin lispro, including pharmacokinetics (PKs), pharmacodynamics, clinical efficacy, safety and immunogenicity. Expert opinion: The rising treatment costs of diabetes mellitus poses a challenge to public health enterprises worldwide. The development of biosimilars is probably a good choice to solve this conundrum. Based on the available clinical trials, it is confirmed that SAR342434 is equivalent to the reference insulin lispro, with similar pharmacodynamics, PKs, anti-hyperglycemic efficacy and safety. These attributes show the good potential of SAR342434 for serving as an alternative to achieve the glycemic control in patients with diabetes mellitus. PMID- 30295084 TI - Surgical Technique and Anatomical Considerations for the Modified L'Episcopo Tendon Transfer. AB - BACKGROUND: Birth brachial plexus injury usually affects the upper trunks of the brachial plexus and can cause substantial loss of active shoulder external rotation and abduction. Due to the unbalanced rotational forces acting at the glenohumeral joint, the natural history of the condition involves progressive glenohumeral joint dysplasia with associated upper limb dysfunction. Surgical reconstruction methods have been described previously by Sever and L'Episcopo, and modified by Hoffer and Roper to release the adduction contracture and to restore external rotation and shoulder abduction. METHODS: The authors describe their preferred technique for contracture release and tendon transfer to improve external rotation and shoulder abduction. Pertinent anatomy and highlights of surgical exposure are reviewed. RESULTS: The senior author has utilized this technique with consistent clinical outcomes to improve shoulder function for patients with persisting nerve palsy associated with birth brachial plexus injury. A review of the literature supports utilization of this technique. CONCLUSIONS: Transfer of the latissimus dorsi and teres major to the posterior rotator cuff for reanimation of shoulder abduction and external rotation deficits associated with birth brachial plexus injury is a safe and reliable technique. Careful patient selection and attention to surgical detail are critical for optimal outcomes. PMID- 30295085 TI - Type D personality and social relations in adults with diabetes: results from diabetes MILES - The Netherlands. AB - OBJECTIVE: To examine whether individual differences in Type D personality (combination of negative affectivity (NA) and social inhibition (SI)) could explain heterogeneity in perceived social support and relationship adjustment (intimate partner relationship) among people living with diabetes. DESIGN: In the Diabetes MILES-The Netherlands survey, 621 adults with type 1 or type 2 diabetes (54% female, age: 56 +/- 14 years) completed measures of Type D personality (DS14), perceived social support and relationship adjustment. We used established DS14 cut-off scores to indicate Type D personality, high NA only, high SI only and reference groups. RESULTS: Participants from the Type D and NA only groups perceived lower levels of social support (Welch[3,259] = 37.27, p < 0.001), and relationship adjustment (Welch[3,191] = 14.74; p < 0.01) than those from the SI only and reference groups. Type D was associated with lower social support (lowest quartile; adjusted OR = 8.73; 95%CI = 5.05 ~ 15.09; p < 0.001) and lower relationship adjustment (lowest quartile; adjusted OR = 3.70; 95%CI = 2.10 ~ 6.53; p < 0.001). Type D was also associated with increased levels of loneliness. CONCLUSION: Participants with Type D and participants with high NA only tend to experience less social support and less relationship adjustment. Type D personality was also associated with more loneliness. Experiencing lower social support and relationship adjustment may complicate coping and self-management in people with diabetes. PMID- 30295086 TI - Hybrid nanocarrier system for guiding and augmenting simvastatin cytotoxic activity against prostate cancer. AB - Prostate cancer is the most common non-skin cancer among men. Though statins are mainly used as antihyperlipidemic drugs, many studies have reported their proapoptotic and antimetastatic activities on prostate cancer. However, the poor solubility and insufficient delivery of statins in tumor site limit their anticancer activity. The present study introduces an efficient hybrid drug delivery system for the treatment of prostate cancer. The system involves the chemical conjugation of Simvastatin (SMV), a statin compound, to acid-terminated poly(D, L-lactic-co-glycolic acid), PLGA chains followed by its conversion into nanoparticles (NPs), with in situ physical incorporation of more SMV and superparamagnetic iron oxide nanoparticles (SPIONS) into the PLGA NPs. The PLGA based hybrid nanocarrier system has been designed in such a way to evade the low bioavailability of SMV, confer sustained release of both encapsulated and chemically conjugated SMV, as well as enhancing the anti-cancer effect of the formula via the magnetic targeting with the aid of the encapsulated SPIONS. Magnetism, morphological and physicochemical characterizations, as well as in vitro release studies were performed. Besides, cytotoxicity on human prostate cancer cell line (PC-3) was evaluated using MTT assay, cell cycle arrest analysis, annexin V/propidium iodide apoptosis assay and ELISA immunoassay for apoptotic enzyme. Optimum PLGA-based hybrid nanocarrier significantly improved the SMV anticancer activity against human prostate cancer cell line through both apoptosis mechanism and retardation of G2-M phase of cell cycle. Also, the up regulation of the Caspase 3 was aligned with cytotoxicity study's findings. PMID- 30295087 TI - Adverse childhood experiences as a predictor of attendance at a health-promotion program. AB - This short-term longitudinal study examined whether adverse childhood experiences predicted attendance at a fitness program. We asked undergraduates participating in a group fitness program at a university to complete measures of mental health and adverse childhood experiences at the start of the semester. Attendance data were obtained from the recreational center at the end of the semester. Adverse childhood experiences predicted attendance after parental education and mental health were taken into account. To our knowledge, this is the first study to demonstrate that more adverse childhood experiences predict lower attendance at a health-promotion program. Findings suggest a need for adverse childhood experiences screening to prevent drop-out. PMID- 30295088 TI - Adding insult to injury: Perceived inequity modulates pain perception. AB - Inequity and pain typically co-appear during disasters or illnesses and have significant effects on health. However, the relationship between inequity and pain perception is poorly understood. Four studies investigated whether perceived inequity modulates pain perception using different priming paradigms and pain measurements. Studies 1-3 consistently revealed that participants perceived pain more intensely and rapidly after inequity priming. Study 4 demonstrated that inequity in cancer patients predicts pain perception after controlling for individual differences in equity sensitivity and pain sensitivity. The findings suggest that equity may help manage adversity in achieving mental and physical health. PMID- 30295089 TI - A series of n-of-1 studies examining the interrelationships between social cognitive theory constructs and physical activity behaviour within individuals. AB - OBJECTIVES: Research supports the ability of social cognitive theory (SCT) to explain physical activity (PA) behaviour, but most studies have examined this theory between individuals in large group studies. The aim of the present study was to examine the interrelationships between SCT constructs and PA within individuals of varying activity levels. DESIGN: Correlational n-of-1 studies. METHODS: Six adults aged 29-65 with varying levels of PA provided daily measures of PA, and completed probe measures over a four-week period of SCT constructs (e.g. barrier self-efficacy, goal setting, planning, social support, outcome expectations, perceived barriers, enjoyment). Data were analysed using cross correlational time series analysis. RESULTS: Cross-correlation analysis showed that at least one SCT construct was associated with PA in five participants, although no individual had the same pattern of associations across the study. On some occasions, SCT constructs predicted subsequent PA, but at other times, PA engagement caused a subsequent change in the SCT construct. There were also examples of PA and SCT constructs being concurrently associated. CONCLUSIONS: SCT factors are associated with variations in PA behaviour, but the cause and effect of these relationships within individuals is complex. PMID- 30295090 TI - Biodegradable Microsphere-Hydrogel Ocular Drug Delivery System for Controlled and Extended Release of Bioactive Aflibercept In Vitro. AB - PURPOSE: Current standard of care for neovascular eye diseases require repeated intravitreal bolus injections of anti-vascular endothelial growth factors (anti VEGFs). The purpose of this study was to validate a degradable microsphere thermoresponsive hydrogel drug delivery system (DDS) capable of releasing bioactive aflibercept in a controlled and extended manner for 6 months. MATERIALS AND METHODS: The DDS was fabricated by suspending aflibercept-loaded poly(lactic co-glycolic acid) microspheres within a biodegradable poly(ethylene glycol)-co-(l lactic acid) diacrylate/N-isopropylacrylamide (PEG-PLLA-DA/NIPAAm) thermoresponsive hydrogel. Encapsulation efficiency of DDSs and in vitro release profiles were characterized by iodine-125 radiolabeled aflibercept. The degradation of hydrogel was determined by dry weight changes. The cytotoxicity from degraded DDS byproducts was investigated by quantifying cell viability using LIVE/DEAD(r) assay. In addition, dot blot and enzyme-linked immunosorbent assay were used to determine the bioactivity of released drug. Finally, morphology of microspheres and hydrogel were investigated by cryo-scanning electron microscopy before and after thermal transformation. RESULTS: The microsphere-hydrogel DDS was capable of releasing bioactive aflibercept in a controlled and extended manner for 6 months. The amount and rate of aflibercept release can be controlled by both the cross-linker concentration and microspheres load amount. The initial burst (release within 24 h) was from 37.35 +/- 4.92 to 74.56 +/- 6.16 ug (2 and 3 mM hydrogel, each loaded with 10 and 20 mg/ml of microspheres, respectively), followed by controlled drug release of 0.07-0.15 ug/day. Higher PEG-PLLA-DA concentration (3 mM) degraded faster than the lower concentration (2 mM). No significant cytotoxicity from degraded DDS byproducts was found for all investigated time points. Bioactivity of released drug was maintained at therapeutic level over entire release period. CONCLUSIONS: The microsphere hydrogel DDS is safe and can deliver bioactive aflibercept in a controlled manner. This may provide a significant advantage over current bolus injection therapies in the treatment of ocular neovascularization. PMID- 30295091 TI - Gynecological-endocrinological aspects in women carriers of BRCA1/2 gene mutations. AB - Women carriers of mutations in the genes BRCA1 and BRCA2 coding for tumor suppressor proteins are at high risk of developing breast and ovarian cancers. Hereditary breast and ovarian cancers due to BRCA pathogenic mutations occur at earlier ages: mean age 43 years at diagnosis of breast cancer for BRCA1 mutations; onset of ovarian cancer up to 10-21% by age 50 years. Preventive strategies are then defined in the reproductive years. The National Comprehensive Cancer Network (NCCN) guidelines define that BRCA1/2 genetic testing should begin with the affected cancer individual (BRCA1/2 full sequencing); then, family members should be tested for the specific gene mutation found. A woman known to be a carrier needs a strict specific surveillance strategy to achieve early diagnosis. The NCCN proposes breast imageneological surveillance beginning at age 25 years; ovarian surveillance beginning at age 30-35 years. Concomitantly, risk reducing strategies should be analyzed: surgical or pharmacological. When prophylactic bilateral salpingo-oophorectomy is performed before menopause, estrogen replacement therapy could be required. For BRCA, we review the risks of cancer in mutations carriers, criteria for genetic testing, surveillance and risk reduction strategies, and the safety of prescribing hormone therapy when needed. PMID- 30295092 TI - Science and Terminology in-between Empires: Ukrainian Science in a Search for its Language in the nineteenth century. AB - Ukrainian science and its terminology in the nineteenth century experienced a number of twists and turns. Divided between two empires, it lacked institutions, scholars pursuing it, and a unified literary language. One could even say that until the late nineteenth century there was a possibility for two communities with two literary languages to emerge - Ruthenian (Habsburg Empire) and Ukrainian (Russian Empire). Eventually, both communities and languages merged. This article tracks the meanderings of this process, arguing that scholarly publications played a crucial role in shaping the standard for the scientific language. The article follows the biography of the naturalist Ivan Verhrats'kyi (1846-1919), the author of the first dictionaries of naturalist terminology in Ruthenian in 1860, a translator and author of textbooks, and the head of the Mathematical Naturalist-Medical Section of the Shevchenko Society in L'viv. He thus shaped many Ruthenian, and then Ruthenian-Ukrainian scholarly projects. Initially successful with his approach to making the Ruthenian scientific language vernacular, in the 1890s his approach was losing ground to the internationalization of vocabulary and to the growing pressure toward the unification of Ruthenian and Ukrainian. Finally, in the beginning of the twentieth century, Verhrats'kyi became marginalized within the Ukrainian scholarly community. By discussing the history of a minority language within imperial structures, I argue that the media in which scholarly work was published requires special attention. In the Ruthenin-Ukrainian case, they determined the standard for scientific language. Lacking professional journals, Ruthenian scholars published in the 1860s-late 1880s in popular newspapers and in school textbooks, requiring them to use a language that was near to the spoken tongue of the Habsburg province. Once the political situation changed, favoring Ruthenian Ukrainian unification, and scholarly journals appeared and transgressed the imperial boundary, the favored language had to be transimperial, ousting out the vernacular.

AB - INTRODUCTION: Although the majority of women with endometrial cancer have a favorable prognosis due to early symptoms, 15-20% have high-risk disease features and are at increased risk of recurrence. In order to improve prognosis for these patients, several trials have compared chemotherapy (CT), radiotherapy (RT) or the combination of CTRT. Areas covered: This review focuses on the current evidence on adjuvant treatment for women with high-risk endometrial cancer and future perspectives. Expert commentary: For stage I-II high-risk endometrial cancer, external beam radiotherapy ensured good local control and no significant benefit in progression-free or overall survival was found with the addition of chemotherapy in 2 recent randomized trials. For women with stage III disease, the combination of chemotherapy and radiotherapy improved progression-free survival with a non-significant improvement of overall survival. Adjuvant chemotherapy alone resulted in higher rates of pelvic and para-aortic recurrence. More toxicity and reduced quality of life were found during and after adjuvant CTRT. It is essential to discuss the benefits and disadvantages of chemotherapy and radiotherapy with individual patients for shared decision-making. Translational research is ongoing to further characterize individual tumors, identify sensitivity to (immuno)therapies and find new treatment targets to improve outcomes.

AB - INTRODUCTION: Adult-onset Still's disease (AOSD) is a rare inflammatory disorder typically characterized by fever, arthritis, and hyperferritinemia. Concerning AOSD pathogenesis, it is categorized as a multigenic autoinflammatory disease, at the 'crossroads' of autoinflammatory and autoimmune diseases, because of the involvement of both arms of immune system. Areas covered: This work is conceived as narrative overview assessing the pathogenesis of AOSD. We performed a narrative synthesis of published information, summarizing the contents of previous studies and providing a possible rationale for future researches. MedLine database was searched for identification of suitable studies. In reporting the available evidence, we described the results according to distinct pathogenic steps associated with different clinical features of the disease. Expert commentary: AOSD is a systemic severe inflammatory disorder of unknown etiology affecting young adults. Although pathogenesis of the disease is not fully clarified, the role of the pro-inflammatory cytokines is well-recognized and biologic drugs, blocking these molecules, are routinely used in clinical practice. Finally, given that multiple recent lines of evidence have suggested new insights in AOSD pathogenesis, new therapeutic targets have been highlighted and the results of studies with new drugs could further improve the management of these patients.

AB - INTRODUCTION: P-wave duration (PWD) is an electrocardiographic (ECG) marker reflecting atrial conduction, and studies have shown that its prolongation is associated with atrial fibrillation. Areas covered: This review addresses the relationship between PWD and atrial fibrillation, how anatomic and physiologic changes in the atria potentiate the risk for atrial fibrillation, and how these atrial anatomic and physiologic changes relate to PWD. Other P-wave related entities, such as P-wave terminal force in V1, PR interval, and P wave axis are also addressed. Expert commentary: Atrial fibrillation is a manifestation of the underlying atrial disease. Fibrotic collagen deposition interrupts the electrical flow and thus can potentiate the transition from sinus rhythm to atrial fibrillation. PWD is an ECG parameter that provides insight into the intricacies of the atria and could be a useful marker for assessing the risk for atrial fibrillation. The main obstacle for broad utilization of PWD is that it is not routinely reported on the printout of the electrocardiogram.

AB - INTRODUCTION: Pancreatic cancer is a highly malignant disease with high treatment resistance. Many patients are diagnosed in a very advanced state, and few patients can be curatively resected. With FOLFIRINOX and nab-paclitaxel plus gemcitabine, the prognosis of advanced pancreatic cancer has improved, yet many patients cannot survive longer than a year. Therefore, new therapeutic approaches are needed. Cancer vaccine therapy is characterized by controlling cancer by a cancer-specific immune reaction with few adverse events. Thus, a cancer peptide vaccine is considered promising for pancreatic cancer patients, who are often in poor general condition at diagnosis. Areas covered: This article reviews available data from recent clinical trials of the novel cancer vaccine therapy in combination with traditional chemotherapy or radiotherapy for pancreatic cancer, and the prospect will be described. Expert commentary: In clinical trials of the novel cancer vaccine therapy in combination with traditional therapy, many studies have failed to outperform traditional therapy, although some effects were recognized in subgroups. What is necessary in the future for cancer vaccine therapy to improve the prognosis of pancreatic cancer is combination of immune checkpoint blockade to release immune escape mechanism and combination with strong multi-drug combination chemotherapy. PMID- 30295098 TI - Embracing the polypill as a cardiovascular therapeutic: is this the best strategy? AB - INTRODUCTION: Cardiovascular disease (CVD) is an important cause of mortality and morbidity worldwide. CVD morbidity and mortality are associated with significant financial costs related to hospitalization, medication, and lost productivity. The concept of the 'polypill' for the reduction of cardiovascular risk was proposed in 2000. A polypill is a fixed combination of drugs in a single tablet or capsule. The initial polypill consisted of three different classes of antihypertensive drugs (each at half dose), in addition to aspirin, a statin, and folic acid. The challenge today is to produce polypills containing drugs with established efficacy and complementary actions. Areas covered: The authors provide their expert perspectives on the polypill and consider the randomized clinical trials that have evaluated the safety, efficacy, adherence, and cost effectiveness of polypills. Expert opinion: The polypill makes prescribing easier by reducing the need for complex treatment algorithms and dose titration. It also appears to be cost-effective. However, there are several issues that need to be addressed before the polypill can be used routinely. A single polypill formulation may not be suitable for all patients. It may be necessary to develop several types of polypill to meet the needs of different patient groups. PMID- 30295099 TI - Administrative ethics: Good intentions, bad decisions. AB - The Canadian healthcare system is costly. Each day, health leaders must make decisions about what healthcare services will be offered, how they will be funded, to whom they will be made available, and within what administrative and clinical structure they will be managed and delivered. These decisions, their justification, and the ethics framework employed can vary greatly across the Canadian landscape. These high-stakes decisions must not only draw upon healthcare science but the science of business finance, risk management, and organizational design. However, in equal measure and often overlooked, these decisions must draw upon our values, upon our ethics. Sometimes we get it right, and other times, decidedly less so. When timely and fair access to effective and efficient healthcare services is not rendered, matters of justice, fairness, rights, and a host of other constructs are often cited. However, these important constructs are commonly misunderstood, contributing, in part, to well-intentioned but ultimately unethical decisions. PMID- 30295100 TI - Ethical leadership and why health information management professionals need to be involved. Commentary on Health information is central to changes in healthcare: a clinician's view (Hoyle, 2018). AB - Philip Hoyle presents a compelling argument for the significant and highly valued role that the management of health information plays in the Australian healthcare system and the delivery of health services in this country. However, he also brings to our attention the ill-defined nature of the ethical oversight of this very information. Hoyle uses words such as "honesty," "commitment to beneficence," "commitment to equity" and "respect for variation" when describing the characteristics of ethical leadership. He singles out health information management professionals - Health Information Managers (HIMs) and Clinical Coders (CCs) - as the key professional group who need to step up and seize the initiative, get conversations going, form partnerships, do research and publish findings, so the knowledge and insights that the health information management profession has the potential to offer are not only more widely known and understood but also more useful to others working in the healthcare arena. Hoyle calls on health information management professionals to step out from behind the scenes and take responsibility for the ethical use of the information they help produce. Hoyle's words resonated powerfully with me, particularly with respect to the clinical coding workforce in Australia, which is made up of trained CCs and qualified HIMs. In a truly ethical environment, HIMs and CCs would not be asked to meet performance indicators for increased funding metrics or to change codes to avoid triggering certain indicators; they would simply be asked to ensure complete, accurate coding for every episode of care. This is what ethical leadership would look like. I am concerned about our clinical coding workforce. I am now asking, are our CCs and HIMs up to the task of taking back absolute and unchallenged ownership of their particular skill set, which makes them the keepers of the clinical coding standards and the experts in accurate and complete code assignment?

AB - Converging lines of research highlight the significance of cognitive and behavioral flexibility in the etiology, maintenance, and treatment of fear and anxiety disorders. We have developed a Special Issue to highlight recent empirical investigations, contemporary theory, and novel directions for future study. It is hoped that this special issue will (a) underscore the centrality of cognitive and behavioral flexibility to fear- and anxiety-related psychopathology, (b) call attention to cognitive science approaches investigating related neuropsychological correlates, and (c) highlight novel experimental and theoretical research on germane contextual factors. PMID- 30295103 TI - Nephroprotective Effect of Cilostazol And Verapamil Against Thioacetamide-Induced Toxicity in Rats may Involve Nrf2/HO-1/NQO-1 Signaling Pathway. AB - Cilostazol and verapamil are widely used cardiovascular drugs, explored a beneficial effect on different organs-induced toxicities. We investigated whether the Nrf2 (nuclear erythroid factor 2) and its downstream pathway may be involved in the protective role of these drugs against TAA-induced renal damage. Renal biomarkers (creatinine and urea) and histopathology were observed. Antioxidant and oxidant indicators; superoxide dismutase (SOD), reduced glutathione (GSH), malondialdehyde (MDA), and total nitrite (NO) were also measured. Antioxidant markers like; Nrf2/hemoxegenase-1 (HO-1) and NADPH quinone oxidoreductase -1 (NQO 1) expressions were determined by ELISA and immunohistochemistry. Cilostazol and verapamil pre-treatment improved serum creatinine and urea elevation. Examined drugs have also an ameliorative effect on TAA-induced elevation in MDA and NO activities and antioxidant enzymes; SOD and GSH. Additionally, the pre-treated drugs significantly up-regulated Nrf2/HO-1/NQO-1 expression levels. In conclusion, cilostazol and verapamil exerted their protective effects partially via a Nrf2/HO-1/NQO-1 activation pathway with anti-oxidant roles.

AB - INTRODUCTION: The introduction of proton pump inhibitors (PPIs) into clinical practice has greatly improved our therapeutic approach to acid-related diseases for their efficacy and safety. Areas Covered: The following evidence-based indications for PPI use are acknowledged by many scientific societies: treatment of the various forms and complications of gastroesophageal reflux disease, eradication of H. pylori infection in combination with two or more antibiotics, short- and long-term therapy of H. pylori-negative peptic ulcers, healing, and prevention of NSAID/COXIB-associated gastric ulcers, co-therapy with endoscopic procedures to control upper digestive bleeding and medical treatment of Zollinger Ellison syndrome. Expert Commentary: Despite the above well-defined indications, however, the use of PPIs continues to grow every year in both western and eastern countries and the endless expansion of the PPI market has created important problems for many regulatory authorities for two relevant features: the progressive increase of the costs of therapy and the greater potential harms for the patients. The major reasons for the misuse of PPIs are the prevention of gastro-duodenal ulcers in patients without risk factors and the stress ulcer prophylaxis in non-intensive care units, steroid therapy alone, anti-platelet or anti-coagulant treatment in patients without risk of gastric injury and the overtreatment of functional dyspepsia. PMID- 30295106 TI - Evaluation of the premature chromosome condensation scoring protocol after proton and X-ray irradiation of human peripheral blood lymphocytes at high doses range. AB - PURPOSE OF THE STUDY: One of the main difficulties in radiation dose assessment is cells inability to reach mitosis after exposure to acute radiation. Premature chromosome condensation (PCC) has become an important method used in biological dosimetry in case of exposure to high doses. Various ways to induce PCC including mitotic cells fusion, chemical stimulation with calyculin A or okadaic acid give wide spectrum of application. The main goal of this study was to evaluate the utility of drug-induced PCC scoring procedure by testing 2 experimental modes where 150 and 75 G2/M-PCC phase cells were analyzed after exposure to high dose proton and X-ray radiation. Another aim is to determine the differences in cellular response induced by proton and photon radiation using a HPBL in vitro model as a further extension of our previous studies involving doses up to 4.0 Gy. MATERIALS AND METHODS: Total body exposure was simulated by irradiating whole blood collected from a healthy donor. Whole blood samples were exposed to two radiation types: 60 MeV protons and 250 kVp X-rays in the dose range of 5.0-20.0 Gy, the dose rate for protons was 0.075 and 0.15 Gy/s for X-rays. Post 48 h of human peripheral blood lymphocytes (HPBL) culture, calyculin A was added. After Giemsa staining, chromosome spreads were photographed and manually analyzed by scorers in the G2/M-PCC phase. In order to check the consistency of obtained results all scorers followed identical scoring criteria. Additionally, PCC index kinetics was evaluated for first 500 cells scored. CONCLUSIONS: Here we provide a different method of results analysis. Presented dose-response curves were obtained by calculating the value of counted excess chromosome fragments. The results indicated that obtained dose estimates as adequate in the high dose range till 18.0 Gy for both studied radiation types, giving an opportunity to further improve PCC assay procedure and shorten the analysis time i.e. in case of partial body exposure. Moreover, the study presents preliminary results of HPBL cellular response after proton irradiation at high doses range showing differences of PCC index kinetics for different cell classes and cell distribution.

AB - BACKGROUND: There is considerable need for effective and accessible treatment for opioid use disorder. AIMS: Our study explored differences in buprenorphine treatment retention and duration, with a focus on selected sociodemographic factors and treatment indicators, in two different settings: an office-based buprenorphine induction and stabilization clinic (OBIC) and a community-based primary care clinic (CPC). METHOD: This nonexperimental retrospective chart review compared demographic information and buprenorphine treatment details, including treatment retention and duration. RESULTS: There were no statistically significant differences in buprenorphine treatment indicators between the OBIC and CPC groups, with two exceptions: the number of written buprenorphine prescriptions was significantly greater for the OBIC group, as was the number of filled buprenorphine prescriptions. CONCLUSIONS: Given similar treatment retention and duration in two different buprenorphine treatment settings, our findings suggest that access to buprenorphine treatment in standard integrated care settings can be supplemented by novel treatment structures such as the OBIC in order to increase access to care during the current opioid epidemic. PMID- 30295108 TI - Sweet care against sugar bitterness, designing health-based electronic game. AB - Health-based electronic games present an innovative tool to deal with mental and behavioral disorders as well as physical. An appropriately designed game can optimize health care. The aim of this study was to establish a design for health based electronic games model and to develop a sample game in diabetes. This study was carried out in two phases: first, the design of a health-based electronic game framework and second, the design and production of sweet care game. There were two intended information prerequisites: determination of effective components in models of behavior change and validation of these components on health topics and structural formation of a game. The game framework design was presented. In the second phase, a sample of the game was developed in the field of diabetes. Important components to empower people were ranked using the Friedman test in the following order: self-learning, treatment, mental empowerment, condition management, healthy eating and physical activity. The axis of self-learning received the highest rating from the perspective of the subjects with an average of 3.93 percent. Another part was the game framework with components as follows: application areas, educational content for change behavior, resources, game structure and game production. Finally, the sweet care game was designed on diabetes with educational, technological and clinical content. The health-based electronic game designed on a systematic framework could be applied as a tool to expanding the knowledge base on how to create effective health-based digital games that entertain while promoting behavior change.

AB - OBJECTIVE: Growth differentiation factor-15 (GDF-15) is a stress-induced cytokine and related to the prognosis of cardiovascular diseases. Our purpose is to measure the maternal levels of GDF-15 in patients with early-onset preeclampsia (EOPE) and late-onset preeclampsia (LOPE). METHODS: This cross-sectional study was conducted including 72 pregnant women, 23 with normal pregnancies and 49 with preeclampsia (26 with EOPE and 23 with LOPE). Maternal serum levels of GDF-15 were measured by using enzyme-linked immunosorbent assay kits. RESULTS: The median serum GDF-15 level was found to be the highest in the EOPE group (EOPE: 441.7 pg/ml). The median serum GDF-15 levels were higher in women with preeclampsia than in the control group (309.7 pg/ml vs. 436.6 pg/ml, p: 0.009). CONCLUSION: Our findings suggest GDF-15 increased as a response to endothelial injury caused by cytokines triggered by preeclampsia. PMID- 30295111 TI - Evaluation of a crosswalk between the European Quality of Life Five Dimension Five Level and the Menopause-Specific Quality of Life questionnaire. AB - OBJECTIVES: Postmenopausal (PM) women taking therapies using estrogens plus progestogens (EPTs) can experience side effects (breast pain, vaginal spotting/bleeding). Sensitivity of the European Quality of Life Five Dimension Five Level (EQ-5D-5L) in measuring quality of life of PM women experiencing side effects of EPTs is unknown. A crosswalk between the Menopause-Specific Quality of Life (MENQOL) questionnaire and the EQ-5D-5L was assessed. METHODS: The measures were administered to 352 PM women (side effects = 202; control = 75; untreated = 75) in a non-interventional study. MENQOL total scores, treated as continuous and categorical predictors, were mapped onto EQ-5D-5L utilities using regression. Ordinary least-squares regression using averaged scores over time, goodness of fit, and estimated coefficients was also assessed. RESULTS: Mean age was 53.7 years. The first model (MENQOL as a continuous variable) showed a moderate correlation (-0.589) and statistically significant relationship with the EQ-5D-5L (p < 0.001), with an equation of EQ-5D-5L = 0.992 - 0.042 * MENQOL. The EQ-5D-5L mean scores were comparable (side effects = 0.854; control = 0.927; untreated = 0.836) to MENQOL mean scores estimated in the first model (side effects = 0.865 [standard deviation 0.07]; control = 0.909; untreated = 0.833). Linearity assumptions were supported with MENQOL scores as a categorical predictor. Goodness of fit was moderate (R2 = 0.347; root mean squared error = 0.093). CONCLUSION: The crosswalk supports conversion of MENQOL scores to EQ-5D-5L derived health utilities for group-level analyses in PM women. PMID- 30295112 TI - CD73 expression in tissue granulomas in distinguishing intestinal tuberculosis from Crohn's disease in a South African cohort. AB - INTRODUCTION: Overlap of clinical, endoscopic and radiographic features, coupled with a poor microbiological yield makes differentiating Crohn's disease (CD) from intestinal tuberculosis (ITB) challenging. A potential histological differentiating mechanism is the use of immunohistochemical staining for the mesenchymal stem cell marker CD73, as a pilot study showed ITB but not CD granulomas stained positive for this marker. The aim of this study was to assess the value of CD73 in differentiating ITB from CD granulomas in a South African cohort. METHODS: Patients with confirmed CD or ITB were identified from a pathology database. Tissue sections were reviewed by a pathologist to confirm the presence of granulomas. These were then stained with a mouse monoclonal anti-CD73 antibody. The slides were examined together by a pathologist and gastroenterologist in a blinded manner for anti-CD73 staining around granulomas. RESULTS: Ninety six cases were available for analysis; 50 cases of ITB and 46 cases of CD. Thirty percent of CD granulomas (14/46) stained positive for CD73, whereas CD73 positivity was seen in 52% (26/50) of cases of ITB. This was statistically significant (OR 2.48, 95% CI 1.1-5.72, p = .03). The area under the curve (AUC) was 0.61. Sensitivity of CD73 in predicting ITB was 52% and specificity was 70%. Overall CD73 staining of granulomas correctly classified only 60% of cases. CONCLUSIONS: In our study we have shown that significantly more patients with ITB express CD73 in their granulomas than those with CD. However the relatively poor sensitivity, specificity and AUC make this test unlikely to be of value in our clinical practice. PMID- 30295113 TI - Participants' experiences of an Internet-based cognitive behavioural therapy intervention for tinnitus. AB - OBJECTIVE: This study aimed to explore participants' experiences after undertaking an Internet-based cognitive behavioural therapy intervention (ICBT) for tinnitus. DESIGN: Semi-structured telephone interviews were conducted 6-8 months after participants undertook the ICBT intervention. Qualitative thematic analysis was used to interpret the interview data. STUDY SAMPLE: A purposeful sampling strategy was used to identify a diverse range of participants. Semi structured interviews were carried out with 15 participants. The mean age was 58.5 years, 7 men and 8 women participated. RESULTS: The analysis generated the following main themes: (1) expectations and motivation for doing the intervention, (2) experiences of the intervention, (3) intervention engagement and (4) intervention effects. Most participants' expectations were hopeful that the intervention would lessen the impact of their tinnitus. Aspects of the intervention that were beneficial, as well as difficult, were identified together with the impact they had on engagement. Intervention effects were evident on both tinnitus and activities of daily life. CONCLUSIONS: The benefits described by participants indicate the potential of ICBT as an alternate form of intervention delivery. The difficulties that hampered engagement need to be addressed to enhance the application and to optimise the clinical acceptability of ICBT for tinnitus. PMID- 30295114 TI - Long-term survival in patients with epithelial ovarian cancer following cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC). AB - OBJECTIVE: Despite a high response rate to first-line therapy, prognosis of epithelial ovarian carcinoma (EOC) remains poor. The objective of the present study was to evaluate the frequency of long-term survivors and to identify the prognostic factors associated with long-term survival in a French cohort of 566 patients. METHODS: Patients treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for EOC in 13 French centers between 1991 and 2010 were included. Long-term survivors were defined as patients who survived more than 5 years after HIPEC and CRS, irrespective of relapse. RESULTS: Seventy-eight long-term survivors were analyzed. The median follow-up was 74 months. Median age at the time of first HIPEC was 55.4 years (range [22.6 77.6]. Seven patients had advanced EOC and 71 patients had recurrent EOC (37 patients had platinum-resistant EOC and 32 had platinum-sensitive disease). More than half of the long-term survivors had high-grade serous ovarian cancer (HGSOC). In univariate analysis, age >=50 years (p = .004), peritoneal cancer index (PCI) <= 8 (p = .049) and CA-125 < 100 (p = .02) were associated with long term survival. There was a trend towards an association between higher CC-score and long-term survival (p = .057). CONCLUSION: Age >=50 years, PCI <=8 and CA125 < 100 were associated with long-term survival in univariate analysis. There was a trend towards the significance of CC-score. Platinum-status was not associated with long-term survival. PMID- 30295115 TI - Efficacy of radio-hyperthermo-chemotherapy as salvage therapy for recurrent or residual malignant soft tissue tumors. AB - BACKGROUND: Recurrence after wide excision or residual tumor after an unplanned excision of a malignant soft tissue sarcoma (STS) is a complex problem, due to a higher recurrence rate and poorer survival rate compared with primary resection. Regional hyperthermia was used, with the expectation that it will enhance the anti-tumor effects of chemotherapy and radiotherapy. This study aimed to assess the efficacy of neoadjuvant concomitant radiotherapy, hyperthermia, and chemotherapy (RHC) for salvage of recurrent or residual malignant STS. METHODS: We identified 64 patients with recurrent or residual STS treated between 1994 and 2013. After excluding those with low-grade malignancy, with recurrent bone tumor in the soft tissues, with truncal STS, and who declined to participate, 23 patients (7 with recurrence and 16 with residual tumor) underwent RHC. The histologic diagnoses were undifferentiated pleomorphic sarcoma (n = 11), synovial sarcoma (n = 3), leiomyosarcoma and myxoid liposarcoma (n = 2 each), and other histologic types. As primary outcomes, the 5-year overall survival (OS), distant metastasis-free survival (D-MFS), and local control (LC) rates were evaluated by Kaplan-Meier analysis. RESULTS: The median follow-up period was 112.3 months. The 5-year OS, D-MFS, and LC were 86.4%, 77.4%, and 86.7%, respectively. In the univariate analysis, tumor depth was considered as a negative prognostic factor for OS and D-MFS, and a positive margin was also a negative prognostic factor for OS, D-MFS LC with retained on Cox proportional hazards model in OS, and D-MFS. CONCLUSION: RHC is an effective option for salvage treatment of recurrent and residual STS. PMID- 30295116 TI - Effects of serotonin depletion and dopamine depletion on bimodal divided attention. AB - OBJECTIVES: This study aimed to explore the effects of acute phenylalanine tyrosine depletion (APTD) and acute tryptophan depletion (ATD) on bimodal divided attention. A balanced amino acid mixture (BAL) served as control condition. METHODS: 54 healthy adults (age: M = 23.8 years) were randomly assigned to APTD, ATD or BAL in a double-blind, between-subject approach. Divided attention was assessed after 4 hours. Blood samples were taken before and 6 hours after challenge intake. RESULTS: Amino acid concentrations following challenge intake significantly decreased (all p <= .01). There was a significant difference in the mean reaction time (RT) towards auditory stimuli, but not towards visual stimuli between the groups. Post-hoc comparison of mean RT's (auditory stimuli) showed a significant difference between ATD (RT = 604.0 ms, SD = 56.9 ms) and APTD (RT = 556.4 ms, SD = 54.2 ms; p = .037), but no RT-difference between ATD and BAL or APTD and BAL (RT = 573.6 ms, SD = 45.7 ms). CONCLUSIONS: The results indicate a possible dissociation between the effects of a diminished brain 5-HT and DA synthesis on the performance in a bimodal divided attention task. The difference was exclusively observed within the RT towards auditory signals. PMID- 30295117 TI - Guide the way: Tutored reflection facilitates professional identity formation.

PMID- 30295119 TI - Microbubble-assisted MRI-guided focused ultrasound for hyperthermia at reduced power levels. AB - PURPOSE: Ultrasound contrast agent microbubbles were combined with magnetic resonance imaging (MRI)-guided focused ultrasound (MRgFUS) as a means to achieve mild hyperthermia at reduced power levels. METHODS: MRgFUS hyperthermia (42 degrees C for 20 min) was evaluated in rabbit thigh muscle or Vx2 tumors using infusions of microbubbles (Definity, 20 uL/kg) or saline (sham) administered over 5 min. The impact of treatments on drug uptake was assessed with liposomal doxorubicin (Caelyx, 2.5 mg/kg). Applied power levels before and after the injection of microbubbles or saline were compared, and drug uptake was evaluated with fluorometry of tissues harvested 24 hr post-treatment. RESULTS: MRgFUS hyperthermia in muscle and tumors resulted in accurate temperature control (mean =42.0 degrees C, root mean square error (RMSE) = 0.3 degrees C). The power dropped significantly following the injection of microbubbles in muscle and tumors compared to exposures without microbubbles (-21.9% +/- 12.5% vs -5.9% +/- 7.8%, p = .009 in muscle; -33.8% +/- 9.9% vs -3.0% +/- 7.2%, p < .001 in tumors). Cavitation monitoring indicated emission of subharmonic, ultraharmonic, and elevated levels of fourth to sixth harmonic frequencies following microbubble injection. The drug delivery was elevated significantly in muscle with the use of microbubble-assisted relative to conventional heating (0.5 +/- 0.5 ng/mg vs 0.20 +/- 0.04 ng/mg, p = .05), whereas in tumors similar levels were found (11 +/- 3 ng/mg vs 16 +/- 4 ng/mg, p = .13). CONCLUSIONS: The finding that microbubbles reduce the applied power requirements for hyperthermia has considerable clinical implications. The elevated levels of drug found in muscle but not tumor tissue suggest a complex interplay between the heating effects of microbubbles with those of enhanced permeabilization and possible vascular damage. PMID- 30295120 TI - Early versus late stage schizophrenia. What markers make the difference? AB - OBJECTIVES: To identify the psychopathological, cognitive, functional, physical health and inflammatory markers that differentiate between early-stage schizophrenia (ESSCH) and late-stage schizophrenia (LSSCH). METHODS: Cross sectional, naturalistic study of 104 patients with SCH. The sample was divided in two groups: 35 ESSCH (<=7 years' duration of illness) and 69 LSSCH (>10 years' duration of illness). STATISTICAL ANALYSIS: chi-square test and Student's t-test and ANCOVA (or Quade test) controlling for age, sex, BMI and number of cigarettes/day. Finally, a binomial logistic regression was made. RESULTS: ESSCH show greater negative symptom severity (t = 2.465, p = 0.015), lower levels of IkappaBalpha (F = 7.644, p = 0.007), were more frequently classified as normal weight (40% vs 18.8%, p = 0.032) compared with LSSCH. The binomial logistic regression model included age (B = 0.127, p = 0.001) and IkappaBalpha (B = 0.025, p = 0.002) and accounted for 38.9% of the variance (model df =7, chi-square =41.841, p < 0.0001). CONCLUSIONS: Age and IkappaBalpha are the unique markers that differentiate between ESSCH patients whose duration of illness is less than 7 years and LSSCH patients. These results support the hypothesis of toxicity of episodes and highlight the importance of preventing new episodes. PMID- 30295121 TI - Correction. PMID- 30295122 TI - Continuous, label-free, 96-well-based determination of cell migration using confluence measurement. AB - Cellular migration is essential in diverse physiological and pathophysiological processes. Here, we present a protocol for quantitative analysis of migration using confluence detection allowing continuous, non-endpoint measurement with minimal hands-on time under cell incubator conditions. Applicability was tested using substances which enhance (EGF) or inhibit (cytochalasin D, ouabain) migration. Using a gap-closure assay we demonstrate that automated confluence detection monitors cellular migration in the 96-well microplate format. Quantification by % confluence, % cell free-area or % confluence in cell-free area against time, allows detailed analysis of cellular migration. The study describes a practicable approach for continuous, non-endpoint measurement of migration in 96-well microplates and for detailed data analysis, which allows for medium/high-throughput analysis of cellular migration in vitro.

AB - BACKGROUND: For the treatment of acute Achilles tendon rupture, early rehabilitation after surgical repair is believed to be a useful method. The purpose of this study was to evaluate the outcome of open tenorrhaphy followed by early rehabilitation. METHODS: A total of 112 patients who underwent open repair and early rehabilitation for acute Achilles tendon rupture from January 2003 to March 2015 were retrospectively reviewed. These 112 patients (80 men, 32 women) had an average age of 43.1 years (22-62 years), and the mean follow-up period was 91.8 months (12-171 months). A short leg cast was applied postoperatively for an average of 16.5 days (12-20 days). The mean duration of bracing was 6.9 weeks (6 8 weeks). Each patient was assessed based on range of motion, single heel raising test, calf circumference compared to the contralateral limb, ability to return to previous activity, the Arner-Lindholm scale, and the American orthopaedic foot and ankle society (AOFAS) hind foot scale. Isokinetic plantar flexion power was also checked. RESULTS: All patients were fully satisfied (AOFAS >= 90) with the treatment results, and 96 patients were able to return to their previous athletic activities. As assessed by the Arner-Lindholm scale, 103 cases were rated as excellent and the other 9 cases were rated as good. At the 1-year follow-up period, single heel raise and hopping was possible in every patient. Compared to the contralateral side, 10 subjects (8.9%) had minor limitation of dorsiflexion motion, and an average of 1.6 cm calf circumference difference without functional disabilities. There were no major complications such as re-rupture, nerve injury, or infection. CONCLUSION: For acute Achilles tendon ruptures, open surgical repair with optimal length restoration, followed by earlier rehabilitation results in good functional outcomes and a successful return to pre-injury levels of physical activity without major complications. LEVEL OF EVIDENCE: Level IV. PMID- 30295124 TI - Endosomal microautophagy is an integrated part of the autophagic response to amino acid starvation. AB - Starvation is a fundamental type of stress naturally occurring in biological systems. All organisms have therefore evolved different safeguard mechanisms to cope with deficiencies in various types of nutrients. Cells, from yeast to humans, typically respond to amino acid starvation by initiating degradation of cellular components by inducing autophagy. This degradation releases metabolic building blocks to sustain essential core cellular processes. Increasing evidence indicates that starvation-induced autophagy also acts to prepare cells for prolonged starvation by degrading key regulators of different cellular processes. In a recent study, we found that within the first hours of amino acid starvation cells elicit an autophagic response causing rapid degradation of specific proteins. The response is executed independently of both MTOR and canonical macroautophagy. Based on RNAi-mediated knockdown of essential components of the Endosomal Sorting Complex Required for Transport (ESCRT) machinery and electron microscopy we conclude that the response relies on some sort of endosomal microautophagy, hence vesicle budding into endosomes. Substantiated by the different substrates that are selectively degraded by this novel pathway we propose that the response predominantly acts to prepare cells for prolonged starvation. Intriguingly, this includes shutting down selective macroautophagy in preparation for a massive induction of bulk macroautophagy. PMID- 30295125 TI - Development of custom RF coils for use in a small animal platform for magnetic resonance-guided focused ultrasound hyperthermia compatible with a clinical MRI scanner. AB - Three different magnetic resonance imaging (MRI) coils were developed and assessed for use with an experimental platform designed to generate hyperthermia in mice using magnetic resonance-guided focused ultrasound (MRgFUS). An ergonomic animal treatment bed was integrated with MRI coils. Three different coil designs optimized for small targets were tested, and performance in targeting and conducting accurate temperature imaging was evaluated. Two transmit/receive surface coils of different diameters (4 and 7 cm) and a transmit-only/receive only (TORO) coil were used. A software platform was developed to provide real time targeting and temperature maps and to deliver controlled ultrasound exposure. MR thermometry was conducted on different targets, including fresh chicken breasts and mouse cadavers. Multiple experiments were performed in which tissues were targeted with high reproducibility. The TORO coil was the most resilient to temperature drift, resulting in an increase in the calculated temperature of 0.29 +/- 0.12 degrees C, compared to 1.27 +/- 0.13 degrees C and 0.47 +/- 0.04 degrees C for the medium and small coils, respectively. Controlled closed-loop hyperthermia exposure was successfully performed with all three coils. Considering all assessments, the TORO coil exhibited the best overall performance for thermometry acquisition when accounting for stability, precision, temperature spread and resilience to temperature drift. B1 maps of the three coils confirmed that the TORO coil exhibited the most homogeneous B1 field, which explained the improved thermometry performance. The use of coils specifically designed for small targets within the proposed experimental platform allowed accurate thermometry during hyperthermia. PMID- 30295126 TI - Innate/inflammatory bioregulation and clinical effectiveness of whole-body hyperthermia (balneotherapy) in elderly patients with osteoarthritis. AB - OBJECTIVES: Balneotherapy with mud application (mud therapy) is a common hydrothermal intervention for the treatment and rehabilitation of elderly patients with osteoarthritis, leading to anti-inflammatory effects. The main purpose of this investigation was to study a role for regulatory T cells in these anti-inflammatory effects. The second objective was to assess whether the neutrophil-mediated innate response is affected by these anti-inflammatory effects. METHODS: Thirty-six elderly patients with knee osteoarthritis underwent a 10-day cycle of balneotherapy at a spa center. They received daily sessions of whole-body mud therapy at 40-42 degrees C, using mineral-medicinal water and mud. IL-8 and TGF-beta serum concentrations, percentage of circulating CD4+ CD25+ FOXP3+ and CD8+ CD28- regulatory T cells, and neutrophil phagocytic capacity were evaluated at baseline and at the end of the intervention. Clinical assessments included knee flexion and extension angle, pain, stiffness, physical function and health-related quality of life. RESULTS: All clinical outcomes significantly improved. Circulating concentrations of IL-8 and TGF-beta decreased, which correlated with decreased pain and improved knee flexion, respectively. Percentage of CD4+ regulatory T cells decreased, whereas CD8+ regulatory T cells increased. Neutrophil functional capacity increased. CONCLUSIONS: Balneotherapy with mud application was effective in the management of osteoarthritis symptoms. The anti-inflammatory effect mediated by cytokines contributed to the improvement in pain and joint function; and changes in the circulating percentage of regulatory T cells seem to be involved in the anti-inflammatory effects. Improvement in neutrophil function after mud therapy reflects an optimal bioregulatory effect on the inflammatory and innate responses. PMID- 30295128 TI - A highly stable laccase from Bacillus subtilis strain R5: gene cloning and characterization. AB - : The gene encoding copper-dependent laccase from Bacillus subtilis strain R5 was cloned and expressed in Escherichia coli. Initially the recombinant protein was produced in insoluble form as inclusion bodies. Successful attempts were made to produce the recombinant protein in soluble and active form. The laccase activity of the recombinant protein was highly dependent on the presence of copper ions in the growth medium and microaerobic conditions during protein production. The purified enzyme exhibited highest activity at 55 degrees C and pH 7.0. The recombinant protein was highly thermostable, albeit from a mesophilic source, with a half-life of 150 min at 80 degrees C. Similar to temperature, the recombinant protein was stable in the presence of organic solvents and protein denaturants such as urea. Furthermore, the recombinant protein was successfully utilized for the degradation of various synthetic dyes reflecting its potential use in treatment of wastewater in textile industry.

PMID- 30295127 TI - RBM-5 modulates U2AF large subunit-dependent alternative splicing in C. elegans. AB - A key step in pre-mRNA splicing is the recognition of 3' splicing sites by the U2AF large and small subunits, a process regulated by numerous trans-acting splicing factors. How these trans-acting factors interact with U2AF in vivo is unclear. From a screen for suppressors of the temperature-sensitive (ts) lethality of the C. elegans U2AF large subunit gene uaf-1(n4588) mutants, we identified mutations in the RNA binding motif gene rbm-5, a homolog of the tumor suppressor gene RBM5. rbm-5 mutations can suppress uaf-1(n4588) ts-lethality by loss of function and neuronal expression of rbm-5 was sufficient to rescue the suppression. Transcriptome analyses indicate that uaf-1(n4588) affected the expression of numerous genes and rbm-5 mutations can partially reverse the abnormal gene expression to levels similar to that of wild type. Though rbm-5 mutations did not obviously affect alternative splicing per se, they can suppress or enhance, in a gene-specific manner, the altered splicing of genes in uaf 1(n4588) mutants. Specifically, the recognition of a weak 3' splice site was more susceptible to the effect of rbm-5. Our findings provide novel in vivo evidence that RBM-5 can modulate UAF-1-dependent RNA splicing and suggest that RBM5 might interact with U2AF large subunit to affect tumor formation.

AB - : We evaluated the import of Arabidopsis catalase to peroxisomes under homogenous transient expression. The amino acids at -11 to -4 from the C-terminus are necessary for catalase import. The results are in agreement with the previous work under stable expression. We first demonstrate that heme-binding sites are important for peroxisomal import, suggesting the importance of catalase folding.

PMID- 30295131 TI - Quantitation and sensory properties of three newly identified pyroglutamyl oligopeptides in sake. AB - Three new peptides: (pGlu)L-ethyl, (pGlu)LFGP-ethyl and (pGlu)LFNP-ethyl, were identified in the search for pyroglutamyl oligopeptide ethyl esters in sake. The ethyl esterified peptides in sake were quantitated using stable isotope dilution analysis and additional quantitation of (pGlu)L was performed using an external standard method. The concentrations of (pGlu)L-ethyl and (pGlu)L in 33 commercial sake samples ranged from 0.16 to 1.57 mg/L and 1.49 to 7.55 mg/L, respectively. The sensory properties of the pyroglutamyl oligopeptide ethyl esters and corresponding non-esterified peptides were examined: the estimated difference threshold of (pGlu)L (2.0 mg/L) and (pGlu)L-ethyl (0.267 mg/L) was exceeded in 32 and 26 samples, respectively. Estimated thresholds of (pGlu)LFGP-ethyl and (pGlu)LFNP-ethyl were often lower than the levels in quantitated sake samples. The sensory effects of these pyroglutamyl dipeptides on a model sake quality may be negative because of their unpleasant taste, however, (pGlu)LFNP-ethyl may be positive because of its mild taste. PMID- 30295130 TI - Unusual Stability Exhibited by (AT)XN12(AT)Y Motif Associated With High Fetal Hemoglobin Levels. AB - Quasi-palindromic sequences (AT)XN12(AT)Y present in HS2 (hypersensitive site) of the human beta-globin locus are known to be significantly associated with increased fetal hemoglobin (HbF) levels. High HbF levels in some adults arise due to pathological conditions such as sickle cell disease and beta-thalassemia. However, elevated levels of HbF are also associated with a reducing morbidity and mortality in patients with beta-thalassemia and thus ameliorate the severity of the disease. Using gel-electrophoresis, ultraviolet (UV)-thermal denaturation and circular dichroism (CD) techniques, we demonstrated that it exhibits a hairpin duplex equilibrium. Intramolecular species (hairpin) were observed in both low as well as high salt concentration in gel assay studies displaying the unusual stability of intramolecular species even at the high counter-ion concentration. Unusual stability of hairpin secondary structures was also demonstrated by the monophasic nature of the melting profiles for the oligonucleotides which persisted at low as well as high salt and oligomer concentrations. Change in CD spectra as a function of oligomer concentration indicates that the bimolecular duplex formation is selectively favored over monomolecular hairpin formation at and above 9 uM oligomer concentration. Thus, we hypothesize that imperfect inverted repeat sequence (AT)XN12(AT)Y of HS2 of beta-globin gene LCR form the unusually stable hairpins which may result in the formation of a cruciform structure that may be recruited for binding by various nuclear proteins that could result in elevated HbF levels.

[Patihis, L., Ho, L. Y., Tingen, I. W., Lilienfeld, S. O., & Loftus, E. F. (2014). Are the "memory wars" over? A scientist-practitioner gap in beliefs about repressed memory. Psychological Science, 25, 519-530.], we documented several group's beliefs on repressed memories and other aspects of how memory works. Here, we present previously unreported data on the beliefs of perhaps the most credible minority in our dataset: memory experts. We provide the statistics and written responses of the beliefs for 17 memory experts. Although memory experts held similarly sceptical beliefs about repressed memory as other research-focused groups, they were significantly more sceptical about repressed memory compared to practitioners, students and the public. Although a minority of memory experts wrote that they maintained an open mind about repressed memories - citing research such as retrieval inhibition - all of the memory experts emphasised the dangers of memory distortion. PMID- 30295133 TI - British Journal of Biomedical Science in 2018: what have we learned? AB - In 2018 the British Journal of Biomedical Science published one guideline (in reproductive science) and 40 research articles in the various disciplines the comprise biomedical science. The latter were 24 original articles and 16 'In Brief' short reports. Of these, 23 are of note to only one of the sub-disciplines (seven each to biochemists and microbiologists, six to cell pathologists, and one each to cytologists, immunologists and reproductive scientists). Reflecting the increasing complexity of laboratory science, thirteen papers crossed one boundary (three papers each relevant to biochemists and immunologists, and to haematologists and biochemists), whilst four papers were relevant to three or more disciplines. Indeed, biochemical techniques were used in 18 papers, microbiological techniques in 9, whilst histopathology was relevant to 11 papers. Notably, 20 papers used techniques in chromosome analysis and molecular genetics. The present report will summarise key aspects of these publications that are of greatest relevance to laboratory scientists. PMID- 30295134 TI - Changes of mediolateral soft tissue gaps in total knee arthroplasty after suturing medial extensor in navigation. AB - PURPOSE: Aim is to investigate the changes of mediolateral soft tissue gaps in total knee arthroplasty (TKA) after suturing medial extensor. METHODS AND MATERIALS: We compared the differences of medial and lateral gap values that were shown by the computer navigation at 0 degrees , 45 degrees , 90 degrees , and 120 degrees knee flexion during patella in situ and during patella repaired by a towel clip on two constant sites. Fifty consecutive knees (43 patients) scheduled for TKA due to varus knee osteoarthritis, from February 2017 to May 2017, were enrolled in this prospective study. RESULTS: The medial gaps with patella repaired were significantly lower ( p < 0.05) than the medial gaps with patella in situ at 45 degrees , 90 degrees , and 120 degrees knee flexion. Differences in the medial gap were largest at 90, with the difference of 0.87 mm. Twenty-four of 50 cases (48%) showed medial gap differences of 1 mm or over, and 13 of 50 cases (26%) showed medial gap differences of 2 mm or over. The variation in the medial gap at 90 degrees following patellar repair showed significant association (correlation coefficient = 0.78, p = 0.001) with the difference between medial and lateral gaps (medial gap - lateral gap) at 90 degrees of patella in situ. At 90 degrees knee flexion, when the medial and lateral gap difference in patella in situ was 1 mm or less, 73.5% (25/34) of the cases showed variation in the medial gap of less than 1 mm after patellar repair. CONCLUSION: During TKA, while measuring the medial gap with patella in situ, overestimation might occur, especially in the position of knee flexion. Thus, reevaluation using towel clips should be considered when the medial and lateral gap difference is 1 mm or larger when patella in situ during evaluation of the medial and lateral gaps at 90 degrees knee flexion. PMID- 30295135 TI - Nurses developing confidence and competence in telehealth: results of a descriptive qualitative study. AB - BACKGROUND: The widespread use of telehealth brings benefits to improve access to healthcare for rural and remote populations. OBJECTIVE: This study explores what nurses considered important to confidently and competently participate in telehealth. DESIGN: A descriptive qualitative approach was selected. METHODS: Nine New Zealand Registered Nurses who worked in different clinical settings who use telehealth were identified through snowball sampling, and participated in single semi-structured interviews, which were thematically analysed using a general inductive approach. FINDINGS: The nurses' experience of using telehealth, from novice to becoming more proficient, was the main theme identified, with sub themes of: Initial use of telehealth, hands-on training, specialty experience, mentorship and technological know-how. The confidence of nurses using telehealth in this study may reflect their clinical nursing experience. CONCLUSION: Recommendations include the need for more telehealth education and preparation, including incorporating telehealth in under and postgraduate nursing programmes. Additionally, specific telehealth nursing competencies are warranted. PMID- 30295136 TI - Risk of patella baja after opening-wedge high tibial osteotomy. AB - PURPOSE: Medial opening-wedge high tibial osteotomy (OWHTO) induces a lower patellar position, and the subsequent degree of patellar movement may not be predicted preoperatively. The purpose of this study was to clarify the relationship between preoperative and postoperative patellar height based on the correction angle of OWHTO and to create a formula to predict the appearance of patella baja following OWHTO. MATERIALS AND METHODS: Seventy-five knees with varus knee osteoarthritis treated with OWHTO were included in this study. The Caton-Deschamps index was used to evaluate patellar height preoperatively and postoperatively, and the cut-off value for preoperative parameters was determined by a receiver operating characteristic curve to determine the risk ratio for postoperative patella baja. RESULTS: The Caton-Deschamps index significantly decreased from 0.93 to 0.77 after OWHTO ( p < 0.01). The OWHTO correction angle negatively correlated with the delta Caton-Deschamps index ( r = -0.44, p < 0.01), and a 1.7% decrease in the Caton-Deschamps index was shown with a 1 degrees correction angle. Receiver operating characteristic curve analysis revealed that a Caton-Deschamps index of 0.8 was the cutoff for OWHTO; knees with a preoperative Caton-Deschamps index of < 0.8 tended to develop patella baja after OWHTO, with a risk ratio of 9.5 (95% confidence interval [4.3-20.7]). CONCLUSIONS: OWHTO can induce patella baja, and a 1.7% decrease in the Caton Deschamps index was shown with a 1 degrees -correction angle. A preoperative Caton-Deschamps index < 0.8 should be considered a risk factor for postoperative patella baja. LEVEL OF EVIDENCE: Retrospective study, Level IV. PMID- 30295138 TI - The Impact of Chronic Ozone and Particulate Air Pollution on Mortality in Patients With Sepsis Across the United States. AB - OBJECTIVE: The impact of chronic exposure to air pollution on mortality in patients with sepsis is unknown. We attempted to quantify the relationship between air pollution, notably excess ozone, and particulate matter (PM), with in hospital mortality in patients with sepsis nationwide. METHODS: The 2011 Nationwide Inpatient Sample (NIS) was linked with ambient air pollution data from the Environmental Protection Agency for both 8-hour ozone exposure and annual mean 2.5-micron PM (PM2.5) pollution levels. A validated severity of illness model for sepsis using administrative data was used to control for sepsis severity. RESULTS: The records of 8 023 590 hospital admissions from the 2011 NIS sample were analyzed. Of these, there were 444 928 patients who met the Angus definition of sepsis, treated in hospitals for which air pollution data were available. The cohort had an overall mortality of 11.2%. After adjustment for severity of sepsis, increasing exposure to ozone pollution was associated with increased risk of mortality (odds ratio [OR]: 1.04 for each 0.01 ppm increase, 95% confidence interval [CI]: 1.03-1.05; P < .01). Particulate matter was not associated with mortality (OR: 0.99 for each 5 ug/m3 increase, 95% CI: 0.97-1.01; P = .28). When stratified by sepsis source, ozone pollution had a higher impact on patients with pneumonia (OR: 1.06, 95% CI: 1.04-1.08; P < .01) compared to those patients without pneumonia (OR: 1.02, 95% CI: 1.01-1.03; P < .01). CONCLUSION: Exposure to increased levels of ozone but not particulate air pollution was associated with higher risk of mortality in patients with sepsis. This association was strongest in patients with pneumonia but persisted in all sources of sepsis. Further work is needed to understand the relationship between ambient ozone air pollution and sepsis outcomes. PMID- 30295137 TI - Impact of ascending aortic, hemiarch and arch repair on early and long-term outcomes in patients with Stanford A acute aortic dissection. AB - BACKGROUND:: Stanford A acute aortic dissection (AAD) is a life-threatening emergency associated with major morbidity and mortality. The aim of this study was to compare outcomes of three different surgical approaches in patients with Stanford A AAD. METHODS:: From January 2006 to March 2015 a total of 240 consecutive patients with diagnosed Stanford A AAD underwent elective, isolated surgical aortic repair in our centre. Patients were divided into three groups according to the extent of surgical repair: isolated replacement of the ascending aorta, hemiarch replacement and total arch replacement. Patients were followed up for up to 9 years. After univariate analysis multinomial logistic regression was performed for subgroup analysis. Baseline characteristics and endpoints as well as long-term survival were analysed. RESULTS:: There were no statistically significant differences among the three groups in terms of demographics and preoperative baseline and clinical characteristics. Incidence of in-hospital stroke ( p = 0.034), need for reopening due to bleeding ( p = 0.031) and in hospital mortality ( p = 0.017) increased significantly with the extent of the surgical approach. There was no statistical difference in terms of long-term survival ( p = 0.166) among the three groups. Applying multinomial logistic regression for subgroup analysis significantly higher odds for stroke ( p = 0.023), reopening for bleeding ( p = 0.010) and in-hospital mortality ( p = 0.009) for the arch surgery group in comparison to the ascending aorta surgery group as well as significantly higher odds for stroke ( p = 0.029) for the total arch surgery group in comparison to the hemiarch surgery group were identified. CONCLUSIONS:: With Stanford A AAD the incidence of perioperative complications increased significantly with the extent of the surgical approach. Subgroup analysis and long-term follow up in patients undergoing isolated ascending or hemiarch surgery showed a lower incidence of cerebrovascular events compared with surgery for total arch replacement. PMID- 30295139 TI - Platelet-rich plasma decreases fibroblastic activity and woven bone formation with no significant immunohistochemical effect on long-bone healing: An experimental animal study with radiological outcomes. AB - PURPOSE: This study aimed to analyze the immunohistochemical effect of platelet rich plasma (PRP) on healing of long-bone fractures in terms of bone morphogenetic protein-2 (BMP-2), vascular endothelial growth factor (VEGF), the Ki-67 proliferation index, and radiological and histological analyses. METHODS: Sixteen adult rabbits, whose right femoral diaphysis was fractured and fixed with Kirschner wires, were randomly divided into two groups, control and PRP (groups A and B, respectively). PRP was given to group B at 1 week postoperatively, and all animals were euthanized after 12 weeks. Radiographic evaluations were performed periodically. Cortical callus formation, chondroid and woven bone area percentages, osteoblastic and fibroblastic activities, and mature bone formation were examined. The depths of BMP-2 and VEGF staining were measured. The Ki-67 proliferation index was also calculated. RESULTS: The mean radiological union score of group B was significantly higher than that of group A. There were also statistically significant differences between groups A and B in terms of cortical callus formation, woven bone area percentage, fibroblast proliferation, and mature bone formation. Group B had significantly more cortical callus and mature bone formation with less woven bone and fibroblast proliferation. Immunohistochemical analysis revealed no statistically significant difference between the groups in terms of BMP-2 and VEGF staining and the Ki-67 index. CONCLUSIONS: PRP had no effect on BMP-2 or VEGF levels with no increase in the Ki 67 proliferation index, although its application had a positive effect on bone healing by increasing callus and mature bone formation with decreased woven bone and fibroblast proliferation. PMID- 30295140 TI - Over expression of PI3K-AkT reduces apoptosis and increases prostate size in benign prostatic hyperplasia. AB - INTRODUCTION: Even though the role of the phosphatidylinositol 3-kinase (PI3K)/AKT pathways and apoptosis has been well established in prostate cancer, there are no studies regarding alteration in the gene expression of PI3K/AKT pathway and protein expression of apoptotic components and their association with prostate size in Benign prostatic hyperplasia (BPH). Hence the study was designed to analyze the expression pattern of PI3K/AKT and apoptotic components in patients with BPH. MATERIALS AND METHODS: A total of 27 BPH patients aged between 55 and 75 years were recruited in the study and prostatic tissues were obtained after transurethral resection of the prostate. Gene expression levels of PI3K and AKT were assessed by q-PCR. Apoptotic components like BcL-2, caspase-3, caspase 9, BAD, and p-BAD were analyzed by western blotting and immunohistochemistry. RESULTS: Gene expression of PI3K (p85-A) (p = .02), AKT1 (p < .01) and AKT2 (p < .01), and protein expression of BcL-2 (p < .01) and caspase-9 (p < .01) were significantly increased in BPH patients with larger prostate size compared to smaller prostate size. CONCLUSIONS: Overexpression of PI3K/AKT pathway and BcL-2 were associated with reduced apoptosis and increased prostate size in BPH. PMID- 30295141 TI - Reconceptualizing Self-Affirmation With the Trigger and Channel Framework: Lessons From the Health Domain. AB - Self-affirmation-a theory-based technique to affirm the adaptive adequacy of the self-can promote positive behavior change and adaptive outcomes, although effects are variable. We extend a novel framework (Trigger and Channel), proposing three conditions that facilitate self-affirmation-induced behavior change: (a) presence of psychological threat, (b) presence of resources to foster change, and (c) timeliness of the self-affirmation with respect to threat and resources. Using health behavior as a focus, we present meta-analytic evidence demonstrating that when these conditions are met, self-affirmation acts as a psychological trigger into a positive channel of resources that facilitate behavior change. The presence of a timely threat and the availability of timely resources independently predicted larger self-affirmation effects on behavior change, and the two interacted synergistically to predict still larger effects. The results illustrate the conditionality of self-affirmation effects and offer guidelines for when, where, and for whom self-affirmation will be most effective. PMID- 30295142 TI - Characterization of grass carp (Ctenopharyngodon idella) beta-defensin 1: implications for its role in inflammation control. AB - Considering that fish grows in a complex aquatic environment, there is an increasing interest in fish beta-defensins, which is an important group of antimicrobial peptides (AMPs). In this study, grass carp (Ctenopharyngodon idella) beta-defensin 1 (gcdefb1) was isolated using homology cloning technology. Tissue distribution assay showed that gcdefb1 transcripts were expressed with the highest levels in brain and liver, followed by some mucous tissues. To examine gcDefb1 bioactivities, the recombinant gcDefb1 proteins fused with thioredoxin tag protein (Trx) (Trx-Defb1) were induced for production in Escherichia coli Rosetta-gami2(DE3)pLysS under optimal expression conditions. The antibacterial activity of Trx-Defb1 against Aeromonas hydrophila was assessed and its minimum inhibitory concentration (MIC) was 36 MUM. Interestingly, Trx-Defb1 significantly inhibited LPS-induced Tnf-alpha (gcTnf-alpha) secretion and nitric oxide production in grass carp head kidney monocytes/macrophages (HKM), although Trx Defb1 alone had no effect. Our studies provide the first evidence of fish beta defensin 1 engaging in both antimicrobial and inflammation suppression process. PMID- 30295143 TI - Prognostic Value of White Blood Cells Detected for the First Time After Adjuvant Chemotherapy in Primary Operable Non-Small Cell Lung Cancer. AB - OBJECTIVE: To investigate the prognostic value of white blood cells detected for the first time after adjuvant chemotherapy in primary operable non-small cell lung cancer. METHODS: From January 2010 to May 2016, data from 208 patients who underwent surgery for non-small cell lung cancer were retrospectively analyzed. RESULTS: A white blood cell count detected for the first time after adjuvant chemotherapy greater than 7.00 was an independent predictor of poor disease-free survival (Hazard ratio: 1.736, 95% confidence interval: 1.267-2.378; P = .001) and overall survival (Hazard ratio: 1.802, 95% confidence interval: 1.305-2.471; P = .000). In a further study, after myelosuppression, survival analysis indicated that the patients with white blood cell counts <2.5 had poorer survival than patients with blood cell counts 2.5 to 4.0, P = .031. When the analysis was stratified by the type of histology, patients with a white blood cell count >7.00 and increased white blood cell after chemotherapy compared to pretreatment had a poorer prognosis than patients with white blood cell <=7.00 and no increase in white blood cell, P = .000 and P = .002, respectively. We further evaluated the prognosis of the 2 groups in different levels of white blood cell. In the group of patients with white blood cell <=4.0, patients with chemotherapy cycles <=2, and >2 showed no differences (Hazard ratio: 2.346, 95% confidence interval: 0.288 19.073, P = .425). In the group of patients with white blood cell of 4.0 to 7.0, the prognosis of patients with chemotherapy cycles <=2 and patients with chemotherapy cycles >2 showed no difference (Hazard ratio: 0.560, 95% confidence interval: 0.248-1.261, P = .161). In the group of patients with white blood cell >7.0, patients with >2 chemotherapy cycles had a better prognosis than patients with chemotherapy cycles <=2 (Hazard ratio: 0.573, 95% confidence interval: 0.338 0.971, P = .037) Conclusions: The level of white blood cells detected for the first time after adjuvant chemotherapy is an independent risk factor for non small cell lung cancer, especially for patients with nonadenocarcinoma. In addition, the level of white blood cells after postoperative adjuvant chemotherapy and its change compared with pretreatment might also provide useful information regarding the best choice of cycles of adjuvant chemotherapy.

AB - A majority of the potential health benefits of green tea, including the potential to prevent cognitive decline, have been attributed to epigallocatechin gallate (EGCG). Sunrouge is a green tea cultivar that contains EGCG and several other bioactive components such as quercetin, myricetin, cyanidin and delphinidin. We compared the effects of Sunrouge and Yabukita, the most popular Japanese green tea cultivar, on cognitive function in the senescence-accelerated mouse Prone8. These mice were fed an experimental diet containing Sunrouge extract (SRE) or Yabukita extract (YBE). SRE feeding significantly prevented cognitive decline, whereas YBE feeding had little effect. Moreover, SRE feeding prevented elevation of the amyloid-beta42 level while improving the gene expression of neprilysin and decreasing beta-site APP-cleaving enzyme 1 in the brain. These preventive effects of SRE against cognitive decline were attributed to the characteristic composition of Sunrouge and strongly suggest that consumption of this cultivar could protect against age-related cognitive decline.

AB - Little research examines how older queer (lesbian and bisexual) women understand and construct meanings around their body size in the context of individual and community norms and identities. Grounded theory was used to analyse transcripts from 31 interview participants drawn from a health programme in the San Francisco Bay Area. Older queer women of size navigate tensions between body ideals and community ideals in and through their experiences of body size. Women's embodied experiences of fatness, chronic pain and weight changes shifted in tandem with their experience of interactions with other queer women, as well as what bodies and body ideals should be in 'the lesbian community'. This study found that bodily norms and health ideologies are embedded and embodied in communities and navigated through the ongoing formation and configuration of communities over time. Body acceptance movements may be out of touch for this population based on their internalisation of the medical model in which weight loss automatically means improved health. Health interventions for older, queer women of size must be community-based to effectively shift behaviours, norms and expectations around healthy living in fat, ageing bodies. PMID- 30295147 TI - Confidence in accuracy moderates the benefits of retrieval practice. AB - The effect of Retrieval Practice refers to the phenomenon that taking a practice test is more effective for learning than re-study, probably due to the benefit from processes underlying successful retrievals during practice. However, it is rarely studied whether other processes (e.g., metacognitive monitoring) during retrieval practice may also play an important role. In two experiments, we examined whether the effectiveness of retrieval was affected by subjects' confidence in their retrieval success. Subjects studied word-pairs and rated their confidence after each practice test trial (cued-recall in Exp.1, multiple choice in Exp.2), or re-study trial. In both experiments, we observed the classic retrieval practice effect. Moreover, in Exp.2, the benefits differed as a function of subjects' confidence in their retrieval performance: the effect of retrieval practice only emerged for high-confidence trials with higher than 56% confidence. In summary, the retrieval practice only facilitates the retention of correct answers with high confidence. PMID- 30295145 TI - The Noise Exposure Structured Interview (NESI): An Instrument for the Comprehensive Estimation of Lifetime Noise Exposure. AB - Lifetime noise exposure is generally quantified by self-report. The accuracy of retrospective self-report is limited by respondent recall but is also bound to be influenced by reporting procedures. Such procedures are of variable quality in current measures of lifetime noise exposure, and off-the-shelf instruments are not readily available. The Noise Exposure Structured Interview (NESI) represents an attempt to draw together some of the stronger elements of existing procedures and to provide solutions to their outstanding limitations. Reporting is not restricted to prespecified exposure activities and instead encompasses all activities that the respondent has experienced as noisy (defined based on sound level estimated from vocal effort). Changing exposure habits over time are reported by dividing the lifespan into discrete periods in which exposure habits were approximately stable, with life milestones used to aid recall. Exposure duration, sound level, and use of hearing protection are reported for each life period separately. Simple-to-follow methods are provided for the estimation of free-field sound level, the sound level emitted by personal listening devices, and the attenuation provided by hearing protective equipment. An energy-based means of combining the resulting data is supplied, along with a primarily energy based method for incorporating firearm-noise exposure. Finally, the NESI acknowledges the need of some users to tailor the procedures; this flexibility is afforded, and reasonable modifications are described. Competency needs of new users are addressed through detailed interview instructions (including troubleshooting tips) and a demonstration video. Limited evaluation data are available, and future efforts at evaluation are proposed. PMID- 30295148 TI - Preparation of gelatin/genipin nanofibrous membrane for tympanic member repair. AB - The wound healing for tympanic membrane (TM) perforations is one of the most common clinical treatment in otomicrosurgery. Recently, tissue-engineered composites and grafts, also new designs of biomaterials are applied to the management of TM perforation. In this work, a series of gelatin/genipin nanofibrous films were prepared as a patch for repairing TM perforation. Gelatin, a type of biomaterial with excellent electrospinning performance, has been used for preparing the nanofibers. The genipin, as a crosslinking agent, has been blended into the gelatin nanofibers. The reaction between gelatin and genipin engender suitable tensile strength and water-resistance for TM patch. The survival rate of human umbilical vein endothelial cells and fibroblasts demonstrated that the gelatin/genipin nanofiber scaffolds had good biocompatibility, which indicated the genipin was a kind of effective and nontoxic crosslinking agent for improving the mechanical property and water resistance of gelatin films. In short, our work provides a novel macromolecular material with good mechanical properties, water-tolerance and excellent biocompatibility which could be used as a potential patch for TM repair. PMID- 30295149 TI - Interpretation of Optical Coherence Tomography Images for Breast Tissue Assessment. AB - PURPOSE: Initial studies have shown that optical coherence tomography (OCT) is an effective margin-evaluation tool for breast-conserving surgery, but methods for the interpretation of breast OCT images have not been directly studied. In this work, breast pathologies were assessed with a handheld OCT probe. OCT images and corresponding histology were used to develop guidelines for the identification of breast tissue features in OCT images. METHODS: Mastectomy and breast-conserving surgery specimens from 26 women were imaged with a handheld OCT probe. During standard pathology specimen dissection, representative 1-cm * 1-cm tissue regions were grossly identified, assessed with OCT, inked for orientation and image matching purposes, and processed. Histology slides corresponding to the OCT image region were digitally photographed. OCT and histology images from the same region were paired by selecting the best structural matches. RESULTS: In total, 2880 OCT images were acquired from 26 breast specimens (from 26 patients) and 48 matching OCT-histology image pairs were identified. These matched image pairs illustrate tissue types including adipose tissue, dense fibrosis, fibroadipose tissue, blood vessels, regular and hyperplastic ducts and lobules, cysts, cyst, fibroadenoma, invasive ductal carcinoma, invasive lobular carcinoma, ductal carcinoma in situ, calcifications, and biopsy cavities. Differentiation between pathologies was achieved by considering feature boundaries, interior appearance, posterior shadowing or enhancement, and overall morphologic patterns. CONCLUSIONS: This is the first work to systematically catalog the critical features of breast OCT images. The results indicate that OCT can be used to identify and distinguish between benign and malignant features in human breast tissue. PMID- 30295150 TI - Understanding Educational Barriers and Needs of North Korean Defector Nursing Students: A Qualitative Descriptive Study. AB - INTRODUCTION: A growing number of North Korean defector students enter nursing schools in South Korea. Many of them, however, quit nursing school and fail to obtain a nurse license. The purpose of this study was to describe the educational barriers and needs of North Korean defector nursing students. METHOD: A qualitative descriptive approach was employed. Convenience sampling was used, and 14 students participated. Qualitative content analysis was employed. RESULTS: Five themes emerged: lack of preparation for higher education, multiple language barriers, differences in education and culture, lack of support and resources, and lack of information and understanding. DISCUSSION: South Korean government needs to provide North Korean defector students with more practical supportive programs. South Korean nursing schools need to provide more transcultural education for South Korean students and supportive adaptation programs for North Korean defector students to produce culturally competent nurses who provide culturally congruent health care.

PMID- 30295153 TI - Increasing the number of contacts generated during contact tracing interviews. AB - To stem the spread of infectious diseases (e.g., Ebola), epidemiologists conduct contact tracing interviews (CTIs) with infected individuals regarding their contacts who may also be infected. These contact tracing interviews, however, may be vulnerable to deadly errors of omission. A promising technique to maximise recall is the Cognitive Interview (CI), which is grounded in psychological theory. In the present study, participants imagined they were infected with meningococcal meningitis and reported their contacts over the previous three days during either a control interview or a CI. To model the cognitive impairment associated with being sick, half of the participants were interviewed while simultaneously completing a cognitive impairment task. The CI generated more contacts than the control interview. However, when the cognitive impairment task was completed, the CI and the control interview performed similarly. We recommend the CI be considered as an alternative to the control interview, particularly if the interviewee is not temporarily impaired due to distraction or illness. PMID- 30295154 TI - The effect of self-referencing on memory for different kinds of source information. AB - Self-referential processing has been proven to be effective in improving source memory. However, it is unclear whether different types of source information would be consistently enhanced when an item is self-referentially processed. In two experiments, the authors examined the influence of the self (compared with other-referencing and semantic processing) as well as learning intention (incidental/intentional learning) on memory for two types of source information (spatial location and colour) that differ in the amount of cognitive resources they require to be encoded in memory. Results show that self-referencing has enhanced memory for spatial location of words whatever this information is learned intentionally or incidentally, whereas it cannot facilitate memory for the colour of words under the intentional learning condition, nor can it under the incidental condition. These findings suggest that self-referential processing is beneficial in memory improvement but not all-powerful, a source self-reference effect is subject to source information type. PMID- 30295155 TI - The effects of episode similarity on children's reports of a repeated event. AB - Much research has tested techniques to improve children's reporting of episodes from a repeated event by interviewing children after they have experienced multiple episodes of a scripted event. However, these studies have not considered any effects of the similarity shared between event episodes on children's reports. In the current study, 5- to 9-year-olds experienced four episodes of a scripted repeated event that shared a high (n = 76) or low (n = 76) degree of similarity, and were subsequently interviewed about individual episodes. The proportional amount and accuracy of children's reported details were tallied. Children reported proportionally more details and more script deviations after experiencing the high, compared to low, similarity event. Conversely, children were more accurate in their episodic reports when they experienced the low, compared to high, similarity event. The current findings have implications for the generalisability and comparability of past results across laboratory studies. PMID- 30295156 TI - Cortical auditory evoked potentials in cochlear implant listeners via single electrode stimulation in relation to speech perception. AB - The objectives of this study were to investigate the effects of place of stimulation on cortical auditory evoked potentials in relation to speech performance in cochlear implant listeners. It was designed that cortical responses were recorded for single-electrode bursts at apical, medial and basal portions of the electrode array with varying inter-stimulus intervals ranging from 300 ms to 5 s. Latency and amplitude of N1 and P2 peaks were analysed in relation to monosyllabic word scores. The study sample was 44 adult cochlear implant users ranging in age from 28 to 86 years. N1, P2 and N1-P2 amplitudes declined significantly from apical to basal electrodes. The most robust and pronounced responses were recorded for slower stimulation rates (5 s). Speech recognition correlated positively with N1 and N1-P2 amplitudes at the medial electrode. P2 latency showed a significant negative correlation with speech performance at the apical electrode. At last, cortical responses varied significantly depending on the stimulation site and rate. We can objectively quantify speech performance with the N1, N1-P2 amplitude and P2 latency in cochlear implant users. Deafness-related neural degeneration persists even after the cochlear implantation and is more distinct at the base than the apex of the cochlea. PMID- 30295157 TI - 'One of the good guys': sperm donor masculinity and the falling Danish sperm count discourse. AB - Sperm banks in Denmark produce and export donor semen worldwide. The role of the sperm bank is to provide high-quality, safe semen from desirable donors. However, over the last 20 years, global sperm counts are reported to be falling. Along with these discourses comes the implication that poor fertility is a personal failing, which implies a conflation of 'fertility' with 'potency'. This paper draws on qualitative research with Danish sperm donors to explore how donors construct their identities as donors and as the producers of 'good sperm'. Accounts of the drive to produce the best sperm possible and the resultant confidence boost are bound up in ideas about masculine potency and potential and bodily performance and set against a backdrop of a moral panic surrounding the apparently declining Danish sperm count.

AB - INTRODUCTION: Breast cancer mortality rates among African American (AA) women are at 29.2 deaths per 100,000 persons compared with 20.6 deaths per 100,000 persons among Caucasian women. Regular mammography screening may significantly reduce breast cancer mortality and narrow this disparity. This study guided by PEN-3 model aims to explore the relationships and expectations domain and identify perceptions, enablers, and nurturers of regular mammography among AA women. METHOD: As part of an intervention study, in-depth interviews were conducted with 39 AA women recruited from the emergency department of a public university hospital. RESULTS: Women's perceptions included fear and limited knowledge. Enablers identified were cost, socioeconomic, and race-related discrimination, and health care previous experiences. Nurturers identified included observation of family experiences and lack of health-related social support. DISCUSSION: Findings underscore the need to develop culturally tailored interventions to address the issues salient to this population. PMID- 30295160 TI - Endovascular Coil Migration Into the Intestinal Lumen: Two Cases of Successful Nonoperative Management. AB - Endovascular embolization of visceral arteries is commonly performed as treatment for aneurysms, pseudoaneurysms, and emboloradiation of liver tumors; while considered relatively safe, it is not without complications. We are reporting 2 cases of coil migration into the gastrointestinal tract. Patients were successfully managed without endoscopic or surgical coil removal. Patients were followed after discharge and noted to have no further complications from their migrated coils. These cases highlight the success of expectant management for coil migration. We recommend against invasive intervention for coil removal as first-line treatment for endovascular coil migration into the intestinal tract. We urge providers to weigh the risks and benefits of coil removal, prior to invasive intervention. PMID- 30295159 TI - Assessing the level of institutionalization of donor-funded anti-retroviral therapy (ART) programs in health facilities in Uganda: implications for program sustainability. AB - BACKGROUND: In the context of declining international assistance for ART scale-up in Sub-Saharan Africa, the institutionalization of ART programs through integrating them in the organizational routines of health facilities is gaining importance as a program sustainability strategy. OBJECTIVE: The aims of this study were; (i) to compare the level of institutionalization of ART programs in health facilities in Uganda and (ii) to explore reasons for variations in the degree of program institutionalization. METHODS: In Phase One, we utilized Level of Institutionalization Scales developed by Goodman (1993) to measure the degree of institutionalization of ART interventions in 195 health facilities across Uganda. The 45-item questionnaire measured institutionalization based on four sub systems (production, maintenance, supportive, managerial) theorized to make up an organization assessed against two levels of institutionalization; routines (lowest) niche saturation (highest). In Phase Two, four health facilities were purposively selected (2 with the highest and 2 with the lowest institutionalization scores) for a multiple case-study involving semi-structured interviews with ART clinic managers(n = 32), on-site observations and document review. RESULTS: The two highest scoring health facilities had a longer HIV intervention implementation history of between 8 and 11 years. The highest scoring cases associated intervention institutionalization with sustained workforce trainings in ART management, the retention of ART-trained personnel and generating in-house ART manuals. The turnover of ART-proficient staff was identified as a barrier to intervention institutionalization in the lowest-ranked cases. Significant differences in organizational contexts were identified. The two highest-ranked health facilities were well-established, higher-tier hospitals while the lowest scoring health facilities were lower-level health facilities. CONCLUSIONS: The level of institutionalization of ART interventions appeared to be differentiated by level of care in the Ugandan health system. Interventions aimed at strengthening program institutionalization in lower-level health centers at the level of human resources for health could enhance ART scale-up sustainability. PMID- 30295162 TI - Non-conventional therapeutic technique to replace CRISPR bacteria from biofilm by inducible lysogen. AB - Bacteriophage can be an effective means of regulating bacterial populations when conditions allow phage invasion of bacterial colonies. Phage can either infect and lyse a host cell, or insert their DNA into the host cell genome; the latter process is called lysogeny. The clustered regularly interspaced short palindromic repeat (CRISPR) system, linked with CRISPR-associated (Cas) genes, is a regulatory system present in a variety of bacteria which confers immunity against bacteriophage. Studies of the group behaviour of bacteria with CRISPR/Cas systems have provided evidence that CRISPR in lysogenized bacteria can cause an inability to form biofilm. This allows CRISPR-immune bacteria in biofilms to effectively resist phage therapy. Our recent work has described a potential therapeutic technique to eradicate CRISPR-immune bacteria from a biofilm by a continuous influx of lysogens carrying an identical phage sequence. However, this model predicted that the CRISPR-immune population could persist for long times before eradication. Our current focus is on the use of diverse lysogens against CRISPR capable bacterial populations. The goal of this work is to find a suitable strategy which can eradicate bacteria with a CRISPR system through the influx of finite amounts of distinct lysogens over fixed intervals. PMID- 30295161 TI - Do women's perspectives of quality of care during childbirth match with those of providers? A qualitative study in Uttar Pradesh, India. AB - BACKGROUND: Persistently high maternal mortality levels are a concern in developing countries. In India, monetary incentive schemes have increased institutional delivery rates appreciably, but have not been equally successful in reducing maternal mortality. Maternal outcomes are affected by quality of obstetric care and socio-cultural norms. In this light there is need to examine the quality of care provided to women delivering in institutions. OBJECTIVE: This study aimed to examine pregnant women's expectations of high-quality care in public health facilities in Uttar Pradesh, India, and to contrast this with provider's perceptions of the same, as well as the barriers that limit their ability to provide high-quality care. METHODS: A qualitative descriptive analysis was conducted on data from two studies - focus group discussions with rural women in their last trimester of pregnancy (conducted in 2014) to understand women's experience and satisfaction with maternal care services, and in-depth interviews with care providers (conducted in 2016-17) to understand provision of person centred care. Provider perspectives were matched with themes of women's perspectives on quality of childbirth care in facilities. RESULTS: Major themes of care prioritised by women included availability of doctors at the facility; availability of medicines; food; ambulance services; maintenance of cleanliness and hygiene; privacy; good and safe delivery with no complications; client provider interaction; financial cost of care. Many women also voiced no expectation of care, indicating disillusionment from the existing system. Providers concurred with women on all themes of care except availability of doctors, as they felt that trained nurses were proficient in conducting deliveries. CONCLUSIONS: This study shows that women have clear expectations of quality care from facilities where they go to deliver. Understanding their expectations and matching them with providers' perspectives of care is critical for efforts to improve the quality of care and thereby impact maternal outcomes. PMID- 30295163 TI - The Standard for the Exchange of Nonclinical Data (SEND): Challenges and Promises. AB - The Standard for the Exchange of Nonclinical Data (SEND) is an implementation of the Study Data Tabulation Model for nonclinical studies that enables the U.S. Food and Drug Administration (FDA) to modernize and streamline the review process. As a result, patients may benefit from speedier approval of new drugs. However, SEND implementation and compliance can be challenging and require effective cooperation between pharmaceutical companies and contract research organizations. In order to improve Society of Toxicologic Pathology (STP) members' awareness about SEND, including the steps, obstacles, and mistakes to avoid in its implementation while applying for FDA approval, the Career Development and Outreach Committee of the STP sponsored a career development lunchtime series panel discussion entitled "The Standard for the Exchange of Nonclinical Data (SEND): Challenges and Promise" in conjunction with the STP 37th Annual Symposium. The presentations and discussion at this workshop provided perspectives of experts including pathologists and information technology professionals familiar with the SEND submission process and FDA reviewers. This article is designed to provide brief summaries of their talks as well as the questions asked during this well-received panel discussion. PMID- 30295164 TI - Ultra-low-frequency transcutaneous electric nerve stimulation (ULF-TENS) in subjects with craniofacial pain: A retrospective study. AB - OBJECTIVE: The aim of the present study was to evaluate the effects of ultra-low frequency transcutaneous electrical nerve stimulation (ULF-TENS) on pain and electromyographic values in subjects affected by temporomandibular disorders. METHODS: A retrospective evaluation of 80 non-consecutive patients (58 women, 22 men, mean age 35.3 +/- 9.9 years) suffering from pain associated with temporomandibular disorders was performed. The sample was treated with ULF-TENS, and outcomes were evaluated by anamnestic index, dysfunction index, visual analog scale, and surface electromyography of the masticatory muscles. RESULTS: An improvement was seen in pain and electromyographic values. The visual analog scale showed a mean decrease from 8 to 2; surface electromyographic values in the masseter area decreased from 2.7 +/- 0.1 to 1.5 +/- 0.1. CONCLUSION: ULF-TENS seems to be effective in reducing pain symptomatology of subjects affected by temporomandibular disorders, with a reduction in the surface electromyographic activity in the masseter area. PMID- 30295165 TI - Developing Hispolon based novel anticancer therapeutics against human (NF kappabeta) using in silico approach of modelling, docking and protein dynamics. AB - Hispolon is a polyphenolic compound derived from black hoof mushroom (Phellinus linteus) or shaggy bracket mushroom (Inonotus hispidus) which induces the inhibition of cancer promoting NF-kappabeta complex. To develop more potent lead molecules with enhanced anticancer efficiency, mechanism of hispolon mediated Nuclear Factor-kappabeta inhibition has been investigated by molecular modelling and docking. Ten derivatives of hispolon (DRG1-10) have been developed by pharmacophore based design with a view to enhance the anticancer efficacy. Hispolon and its derivatives were further screened for different pharmacological parameters like binding free energy, drug likeliness, ADME, permeability, mutagenicity, toxicity and IC50 to find potent lead molecule. Based on pharmacological validation, comparative MD simulations have been performed for three lead molecules: hispolon, DRG2 and DRG7 complexed with human NF-kappabeta upto 50ns. By analysing different factors like: RMSD, RMSF, Rg, SASA, PCA, Gibb's free energy plots DRG2 have more binding efficiency compared to hispolon and DRG7. In RMSD plot hispolon bound NF-kappabeta has the most deviation within a range between 0.125 to 0.45nm and DRG2 bound complex showed the range between 0.125 to 0.25nm. The residues of NF-kappabeta responsible for hydrophobic interactions with ligand e.g. Met469, Leu522 and Cys533 have lowest fluctuation values in DRG2 bound complex. Average Rg fluctuation for DRG2 bound NF-kappabeta has been recorded under 2.025nm for most of the simulation time which is much less compared to hispolon and DRG7. Gibb's free energy plots also define the highest stability of DRG2 bound NF-kappabeta. PMID- 30295166 TI - Remote post-conditioning and allopurinol reduce ischemia-reperfusion injury in an infra-renal ischemia model. AB - BACKGROUND:: The aim of this study was to evaluate the effects of the antioxidant allopurinol and ischemic post-conditioning on the deleterious effects of ischemia followed by reperfusion (I/R) in a standardized model of ischemia involving infra renal aortic occlusion in rats. METHODS:: The animals were randomly divided into five groups: (A) animals not subjected to ischemia; (B) animals subjected to 2 h of ischemia and reperfusion only once; (C) animals given an allopurinol dose by gavage, then subjected to 2 h of ischemia and reperfusion only once; (D) animals subjected to 2 h of ischemia and post-conditioning and (E) animals that received allopurinol, then subjected to 2 h of ischemia and post-conditioning. The blood samples and small intestine segments were harvested for analysis after 3 days. RESULTS:: The protective effects of the use of allopurinol and ischemic post conditioning were observed by measuring aspartate aminotransferase, alanine aminotransferase and lactate levels. The benefits of post-conditioning were evident from the total antioxidant capacity and creatinine levels, but these could not ascertain any positive effects of allopurinol. The histological analysis of mesentery revealed that both methods were effective in minimizing the harmful effects of the ischemia and reperfusion process. CONCLUSION:: Individual protocols significantly reduced I/R systemic injuries, but no additional protection was observed when the two strategies were combined. PMID- 30295167 TI - Doses of renin-angiotensin system inhibitors but not beta-blockers predict outcome after ST-elevation myocardial infarction. AB - OBJECTIVES: In patients with ST-elevation myocardial infarction (STEMI), it is not clear whether low-dose renin-angiotensin system inhibitors and beta-blockers can result in the same benefits achievable with higher target doses. This observational study aims to investigate whether higher doses of angiotensin converting enzyme inhibitors (ACEI)/angiotensin II receptor blockers (ARB) and beta-blockers can improve outcomes in patients with STEMI. METHODS: We recorded daily doses of ACEI, ARB, and beta-blockers in 331 patients with STEMI. Echocardiographic studies were performed at baseline and were repeated 6 months later. Clinical events, including all-cause death and heart failure, were followed for 2 years. RESULTS: Patients receiving high-dose ACEI/ARB had less increase in left ventricular end-diastolic volume index (LVEDVI) at 6 months. In multivariable linear regression model, ACEI/ARB dose or beta-blocker dose was not an independent predictor of increase in LVEDVI at 6 months. Kaplan-Meier survival curves showed that doses of ACEI/ARB (p = 0.003) and beta-blockers (p = 0.027) were significant predictors of death and heart failure. In multivariable Cox regression analysis, independent predictors of all-cause death and heart failure were diabetes mellitus (p = 0.001), left ventricular ejection fraction (p = 0.026), and ACEI/ARB dose (p = 0.025). Beta-blockers dose was not a predictor of clinical events in multivariable analysis (p = 0.413). CONCLUSION: High-dose ACEI/ARB, but not beta-blocker, was associated with lower rate of all-cause death and heart failure in patients with STEMI. PMID- 30295168 TI - Total contact casting versus traditional dressing in diabetic foot ulcers. AB - This study compared the treatment of total contact casting (TCC) with traditional dressing treatment (TD) in the management of neuropathic diabetic plantar ulcers. Thirty-one patients with plantar ulcers without any gross infection, osteomyelitis or gangrene were randomly assigned to the TCC group (n = 15) or TD group (n = 16). In the experimental group, TCC was applied on the initial visit and subjects were instructed to limit ambulation to one-third of their usual activity. Subjects in the control group (TD) were prescribed dressing changes and were advised against bearing weight on the involved extremity. Ulcers were considered healed if they showed complete skin closure with no drainage. Ulcers were considered not healed if they showed no decrease in size by 6 weeks or if infection developed requiring hospitalization. In the TCC group, 12 of 15 ulcers healed in 48 +/- 7 days; in the TD group, 10 of 16 ulcers healed in 58 +/- 9 days. Comparatively higher rate of ulcer healing with fewer infections was seen in the TCC group. We conclude TCC is a more effective method than dressing for treating diabetic plantar ulcers reducing the risks of amputation. PMID- 30295169 TI - A Brief Introduction to Antibody-Drug Conjugates for Toxicologic Pathologists. AB - Antibody-drug conjugates (ADCs) are an emerging class of anticancer therapeutics, delivering highly cytotoxic molecules directly to cancer cells. ADCs are composed of an antibody, a small molecule drug, and a linker attaching one to another. Antibodies are directed to a large variety of antigens overexpressed on tumor cells, tumor vasculature, or tumor-supporting stroma. After internalization, the ADC is transferred to lysosomes where the cytotoxic component is released, finally killing the target cell. All ADCs are administered via intravenous injection. Once in the circulation, linker stability in plasma is of high importance. In vivo studies in animals address the release of payload over time and typically measure total antibody, conjugated ADC, and free drug. ADC development is driven by ICH (International Council for Harmonisation) guidelines S6(R1) and S9. Dose-limiting toxicities of current ADCs are mainly associated with the payload and correlate well between clinical trials and nonclinical studies in rodents and nonrodents. This mini review is intended to provide general information about ADCs in oncology and shall assist the toxicologic pathologist in correctly interpreting morphological findings acquired in toxicity studies with this entity. PMID- 30295170 TI - Psychosocial and Behavioral Correlates of A1C and Quality of Life Among Young Adults With Diabetes. AB - PURPOSE: The purpose of this study was to evaluate relationships between behavioral and psychosocial constructs, A1C, and diabetes-dependent quality of life (DQoL) among low-socioeconomic status, ethnically diverse young adults with diabetes. METHODS: Using baseline data of 81 participants in the Resilient, Empowered, Active Living (REAL) randomized controlled trial, behavioral, cognitive, affective, and experiential variables were correlated with A1C and DQoL while adjusting for demographic characteristics, and these relationships were examined for potential effect modification. RESULTS: The data indicate that depressive symptoms and satisfaction with daily activities are associated with both A1C and DQoL, while diabetes knowledge and participation in daily activities are associated with neither A1C nor DQoL. Two constructs, diabetes distress and life satisfaction, were associated with DQoL and were unrelated to A1C, while 2 constructs, self-monitoring of blood glucose and medication adherence, were associated with A1C but unrelated to DQoL. These relationships were largely unchanged by adjusting for demographic characteristics, while numerous effect modifications were found. CONCLUSION: The data suggest that when tailoring interventions, depressive symptoms and satisfaction with daily activities may be particularly fruitful intervention targets, as they represent modifiable risk factors that are associated with both A1C and DQoL. PMID- 30295171 TI - Prevalence and determinants of pre-lacteal feeding in South Sudan: a community based survey. AB - BACKGROUND: Pre-lacteal feeding (PLF) is a barrier to optimal breastfeeding and increases the risk of diarrhoea and acute respiratory tract infections in infants.The prevalence and predictors of PLF are not well studied in South Sudan. Understanding the predictors of PLF is crucial in designing interventions to increase exclusive breastfeeding (EBF) rates. OBJECTIVE: To assess the prevalence and factors associated with PLF in Jubek State, South Sudan. METHOD: This was a community based cross-sectional study of 810 mothers of children under two years of age in Jubek State, South Sudan. Mothers were interviewed in their homes using a semi-structured questionnaire to collect data on PLF, socio-demographic and birth characteristics. Multivariable analysis was used to identify factors independently associated with PLF. RESULTS: A total of 426/810 (53 %), 95% confidence interval (CI) [48 %, 59 %] mothers had given pre-lacteal feeds to their infants. The commonest pre-lacteal feeds included glucose solution (54%), water (26%), and infant formula (14%). Having received antenatal breastfeeding counselling decreased the odds of PLF [adjusted odds ratio (AOR) 0.60; 95% CI (0.43, 0.82)]; while discarding of colostrum increased the use of pre-lacteal feeds [AOR 1.57; 95% CI (1.17, 2.11)]. CONCLUSION: The prevalence of PLF in South Sudan is high. Predictors of PLF included lack of breastfeeding counselling and discarding of colostrum. Infant feeding counselling should be given to all pregnant women in the health facilities and communities. The counselling should emphasize the health benefits of colostrum and discourage the practice of discarding it. PMID- 30295172 TI - Critical Appraisal of the Treatment Planning Performance of Volumetric Modulated Arc Therapy by Means of a Dual Layer Stacked Multileaf Collimator for Head and Neck, Breast, and Prostate. AB - PURPOSE: To ascertain whether a new delivery system (the Halcyon system) equipped with dual-layer stacked multileaf collimator operating in a mode, which allows independent, fully interdigitating motion of both layers and 6 flattening filter free energy, could generate plans of high clinical quality compared to a well established delivery system with single layer multileaf collimator. METHODS: Twenty patients in each of the 3 groups (advanced head and neck, breast, and high risk prostate) were selected for an in silico planning study. For each patient, reference plans were developed for volumetric modulated arc therapy technique with 6 MV photon beams from a TrueBeam linear accelerator and compared against the corresponding plans for the Halcyon system. Plan comparison was performed in terms of dose volume histogram quantitative analysis. RESULTS: Concerning the planning target volumes, with identical dose calculation and optimization algorithms and with identical planning techniques, no clinically relevant difference in coverage (D98%), hot spot (D2%), or homogeneity was observed. Similarly, for all the organs at risk, the dosimetric findings showed that (1) all planning constraints were met by the 2 delivery systems and (2) although statistical significant differences were reported for most of the parameters but none of these were judged of potential clinical relevance. CONCLUSION: The data presented confirmed that the new delivery system can generate treatment plans for volumetric modulated arc therapy with the same dosimetric quality of what is achievable with other systems routinely used in the clinics without significantly changing the current practice. Additional studies which customize the optimization parameters for each delivery device would complement the spectrum of investigations. PMID- 30295173 TI - Continuing Education Course #3: Toxicologic Pathology of the Peripheral Nervous System (PNS): Overview, Challenges, and Current Practices. AB - Peripheral nervous system (PNS) toxicity is a frequent adverse effect encountered in patients treated with certain therapeutics (e.g., antiretroviral drugs, cancer chemotherapeutics), in occupational workers exposed to industrial chemicals (e.g., solvents), or during accidental exposures to household chemicals and/or environmental agents (e.g., pesticides). However, the literature and expertise needed for the effective design, conduct, analysis, and reporting of safety studies to identify and define PNS toxicity are hard to find. This half-day course familiarized participants with basic PNS biology; causes and mechanisms of PNS pathology; classic methods and current best practice recommendations for PNS sampling, preparation, and evaluation; and examples of commonly observed lesions and artifacts. Three concluding case presentations synthesized information from the prior technical lectures by presenting real-world examples of lesions caused by drugs and chemicals to demonstrate how PNS toxicity may be addressed in evaluating product safety during nonclinical studies. Topics emphasized comparative and correlative data among animal species used in toxicity studies and clinical evaluation in humans in order to facilitate the translation of animal data into human risk assessment with respect to PNS toxicologic pathology. PMID- 30295174 TI - Acute chest syndrome in sickle cell anaemia: higher serum levels of interleukin-8 and highly sensitive C-reactive proteins are associated with impaired lung function. AB - BACKGROUND: Sickle cell anaemia (SCA) is a chronic inflammatory disorder with multiple organ manifestations including acute and long-term pulmonary dysfunction. AIMS/OBJECTIVES: To assess lung function of children with SCA and determine the possible role of acute chest syndrome (ACS), serum inflammatory cytokines, highly sensitive C-reactive protein (hs-CRP), leucocytes and 25 hydroxyvitamin D on the development of impaired lung function. SUBJECTS AND METHODS: Lung function of 76 children with SCA was determined by spirometer and classified into normal or impaired. Sociodemographic, clinical, haematological, biochemical and immunological data of the two groups were compared by univariate and multivariate analyses. RESULTS: Fifty (65.8%) patients had impaired lung function, comprising of 30.3%, 3.9% and 31.6% with restrictive, obstructive and mixed disease patterns, respectively. Children with previous ACS were 3.6 times more likely to have impaired lung function than those without ACS (82.1% vs 56.3%, p = 0.02, OR 3.6, 95% CI 1.2-10.8). Interleukin (IL)-8 and hs-CRP were significantly higher in patients with impaired lung function (p = 0.02 and <0.001, respectively). Using logistic regression, previous ACS (OR 5.8, 95% CI 1.1-5.8, p = 0.03) and higher serum IL-8 levels (OR 3.0, 95% CI 1.0-8.0, p = 0.02) independently predicted the presence of abnormal lung function. CONCLUSIONS: Lung dysfunction, predominantly restrictive pattern, is common in SCA and is associated with previous ACS and alterations in immunological markers, especially serum IL-8 and hs-CRP.

PMID- 30295175 TI - Considerations for Preclinical Safety Assessment of Adeno-Associated Virus Gene Therapy Products. AB - Progress in understanding the molecular bases of human health and disease in recent decades has flourished making it possible for the field of gene therapy (GT) to offer new possibilities for treating, and even curing, a plethora of medical conditions such as monogenic disorders and metabolic diseases. GT is a therapeutic intervention to genetically alter or modify living cells by means of gene delivery achieved using either viral vectors or nonviral vectors, with adeno associated virus (AAV) vectors constituting market-share majority. Although GT is conceptually attractive, adverse and even fatal iatrogenic complications have marred the initial enthusiasm of clinical successes. The properties of investigational AAV-based GT may pose safety concerns unique from those of small molecule drugs and other macromolecular biologics, such as ectopic or unregulated expression of the transgene, long-term persistence, and off-target distribution. Herein, we discuss considerations in the design of a comprehensive preclinical safety program for AAV-based GT prior to administration in humans. PMID- 30295176 TI - A meta-analysis of techniques to promote motivation for health behaviour change from a self-determination theory perspective. AB - A systematic review and meta-analysis was conducted of the techniques used to promote psychological need satisfaction and motivation within health interventions based on self-determination theory (SDT; Ryan & Deci, 2017. Self determination theory: Basic psychological needs in motivation, development, and wellness. New York, NY: Guilford Press). Eight databases were searched from 1970 to 2017. Studies including a control group and reporting pre- and post intervention ratings of SDT-related psychosocial mediators (namely perceived autonomy support, need satisfaction and motivation) with children or adults were included. Risk of bias was assessed using items from the Cochrane risk of bias tool. 2496 articles were identified of which 74 met inclusion criteria; 80% were RCTs or cluster RCTs. Techniques to promote need supportive environments were coded according to two established taxonomies (BCTv1 and MIT), and 21 SDT specific techniques, and grouped into 18 SDT based strategies. Weighted mean effect sizes were computed using a random effects model; perceived autonomy support g = 0.84, autonomy g = 0.81, competence g = 0.63, relatedness g = 0.28, and motivation g = 0.41. One-to-one interventions resulted in greater competence satisfaction than group-based (g = 0.96 vs. 0.28), and competence satisfaction was greater for adults (g = 0.95) than children (g = 0.11). Meta-regression analysis showed that individual strategies had limited independent impact on outcomes, endorsing the suggestion that a need supportive environment requires the combination of multiple co-acting techniques. PMID- 30295177 TI - Nematode parasites in young cattle: what role for unexpected species? AB - AIMS To investigate the timing of infection of beef calves with sheep nematode species on three sheep and beef farms, and to determine the prevalence of cross infection in calves before weaning across a larger number of farms. METHODS Farms in the Far North, Gisborne and Tararua districts, in the North Island of New Zealand, were enrolled in 2014. Fresh faecal samples were collected from approximately 10 calves on each farm between birth and up to 5 months after weaning. In 2016, faecal samples were collected from calves before weaning from 22 farms across the upper North Island. For both trials faecal samples were assessed for faecal nematode egg counts and cultured to determine parasite genus. For samples from the three farms, larvae were identified to species using a multiplex PCR assay. RESULTS On the three farms, the median percentage of sheep nematode species detected in faecal cultures was 25 (min 3, max 77)%. The main sheep species detected were Cooperia curticei and Haemonchus spp. (putatively contortus). In faecal samples collected before weaning from 22 farms, Haemonchus spp. were present in 19/22 samples, and the median prevalence was 15 (min 0, max 73)% of the total larvae cultured. CONCLUSIONS AND CLINICAL RELEVANCE The implications of sheep nematode species being present in calves should be considered by farmers and veterinarians when undertaking anthelmintic efficacy testing, as they may contribute to false conclusions regarding anthelmintic efficacy. Pre-weaning calves may also be a possible source of contamination and/or refugia for Haemonchus spp. on farms and should be considered when developing parasite control plans for sheep. PMID- 30295178 TI - Have Alcohol Management Plans Reduced Violence Against Women in Cape York, Australia? AB - In 2002/2003, the Queensland Government released a decision that Alcohol Management Plans (AMPs) were to be introduced to most Indigenous communities in Cape York, Australia, in an effort to address violence generally and specifically violence against women and children. By 2008, increased restrictions brought total prohibition in some communities and tightened restrictions in others. This project provides a pre-/postprohibition comparison and analysis of injuries, injuries that involved alcohol and verified police reported assaults. Supporting this are rich community survey data which together aim to elicit the effect restricting alcohol had on violent activity in the communities, particularly for women.

AB - The present study investigated (a) comparisons in rates of rape and sexual assault acknowledgment and (b) a comprehensive multivariate multinomial logistic model predicting rape and sexual assault acknowledgment in a sample of 174 college women who had experienced rape. Significantly more women acknowledged having experienced sexual assault than rape. Greater perceived perpetrator force was associated with increased likelihood of rape and sexual assault acknowledgment. Increased age and greater perceived emotional impact were associated with increased odds of rape acknowledgment. Implications for policy, education, and practice within university settings are discussed.

AB - The present study assessed how individuals used the #NotOkay hashtag on Twitter to respond to Donald Trump's comments about grabbing women by their genitals. We analyzed 652 tweets which included commentary about the hashtag. Three main themes emerged: (a) users' acknowledgment and condemnation of rape culture, (b) Donald Trump and the national state of sexual assault, and (c) engaging men and boys to end violence against women. Our findings emphasize that powerful political leaders can be salient symbols of rape culture, and Twitter is used as a public platform to organize and challenge problematic social discourse and call for action/change. PMID- 30295181 TI - Cubilin, the intrinsic factor-vitamin B12 receptor in development and disease. AB - Gp280/Intrinsic factor-vitamin B12 receptor/Cubilin (CUBN) is a large endocytic receptor serving multiple functions in vitamin B12 homeostasis, renal reabsorption of protein or toxic substances including albumin, vitamin D-binding protein or cadmium.Cubilin is a peripheral membrane protein consisting of 8 epidermal growth factor (EGF)-like repeats and 27 CUB (defined as Complement C1r/C1s, Uegf, BMP1) domains. This structurally unique protein interacts with at least two molecular partners, amnionless (AMN) and Lrp2/Megalin. AMN is involved in appropriate plasma membrane transport of Cubilin whereas Lrp2 is essential for efficient internalization of Cubilin and its ligands. Observations gleaned from animal models with Cubn deficiency or human diseases demonstrate the importance of this protein. In this review addressed to basic research and medical scientists we summarize currently available data on Cubilin and its implication in renal and intestinal biology. We also discuss the role of Cubilin as a modulator of Fgf8 signaling during embryonic development and propose that the Cubilin-Fgf8 interaction may be relevant in human pathology, including in cancer progression, heart or neural tube defects. We finally provide experimental elements suggesting that some aspects of Cubilin physiology might be relevant in drug design. PMID- 30295182 TI - Antimicrobial Capacity of Plant Polyphenols against Gram-positive Bacteria: a Comprehensive Review. AB - BACKGROUND: Multi-drug-resistant bacteria such as Methicillin-resistant Staphylococcus aureus (MRSA) disseminate rapidly amongst patients in healthcare facilities and suppose an increasingly important cause of community-associated infections and associated mortality. The development of effective therapeutic options against resistant bacteria is a public health priority. Plant polyphenols are structurally diverse compounds that have been used for centuries for medicinal purposes, including infections treatment. Based on the existing evidence on the polyphenols' antibacterial capacity, polyphenols may be postulated as an alternative or complementary therapy for infectious diseases. OBJECTIVE: Review the antimicrobial activity of plant polyphenols against Gram positive bacteria, especially against S. aureus and its resistant strains. Determine the main bacterial molecular targets of polyphenols and their potential mechanism of action. METHODOLOGY: The most relevant reports on plant polyphenols' antibacterial activity and their putative molecular targets were studied. We also performed virtual screening of thousand different polyphenols against proteins involved in the peptidoglycan biosynthesis to find potential valuable bioactive compounds. RESULTS: Several polyphenols: phenolic acids, flavonoids (especially flavonols), tannins, lignans, stilbenes and combinations of these in botanical mixtures, have exhibited significant antibacterial activity against resistant and non-resistant Gram-positive bacteria at low ug/mL range MIC values. Their mechanism of action is quite diverse, targeting cell wall, lipid membrane, membrane receptors and ion channels, bacteria metabolites, and biofilm formation. Synergic effects were also demonstrated for some combinations of polyphenols and antibiotics. CONCLUSION: Plant polyphenols mean a promising source of antibacterial agents, either alone or in combination with existing antibiotics, for the development of new antibiotic therapies. PMID- 30295183 TI - Aptamer Based Targeted Drug Delivery Systems: Current Potential and Challenges. AB - Aptamers are single-stranded DNA or RNA with 20-100 nucleotides in length that can specifically bind to target molecules via formed three-dimensional structures. These innovative targeting molecules have attracted an increasing interest in biomedical field. Compared to traditional protein antibodies, aptamers have several advantages, such as small size, high binding affinity, specificity, good biocompatibility, high stability and low immunogenicity, which all contribute to their wide application in biomedical field. Aptamers can bind to the receptors on the cell membrane and mediate themselves or conjugated nanoparticles to enter into cells. Therefore, aptamers can be served as ideal targeting ligands for drug delivery. Since their excellent properties, different aptamer-mediated drug delivery systems had been developed for cancer therapy. This review provides a brief overview of recent advances in drug delivery systems based on aptamers. The advantages, challenges and future prospectives are also discussed. PMID- 30295184 TI - Phenylboronic acid-polymers for biomedical applications. AB - BACKGROUND: Phenylboronic acid-polymers (PBA-polymers) have attracted tremendous attention as potential stimuli-responsive materials with applications in drug delivery depots, scaffolds for tissue engineering, HIV barriers, and biomolecule detecting/sensing platforms. The unique aspect for PBA-polymers is their interactions with diols, which results in reversible, covalent bond formations. This very nature of reversible bonding between boronic acids and diols has been fundamental to their applications in the biomedical area. METHODS: We have searched peer-reviewed articles including reviews from Scopus, PubMed, and Google Scholar with a focus on the 1) chemistry of PBA, 2) synthesis of PBA-polymers, and 3) their biomedical applications. RESULTS: We have summarized approximately 179 papers in this review. Most of the applications described in this review are focused on the unique ability of PBA molecules to interact with diol molecules and the dynamic nature of the resulting boronate esters. The strong sensitivity of boronate ester groups towards the surrounding pH also makes these molecules stimuli responsive. In addition, we also discuss how the re-arrangement of the dynamic boronate ester bonds render PBA-based materials with other unique features such as self-healing and shear thinning. CONCLUSION: The presence of PBA in polymer chain can render it with diverse functions/relativities without changing their intrinsic properties. In this review, we discuss the development of PBA polymers with diverse functions and their biomedical applications with a specific focus on the dynamic nature of boronate ester groups. . PMID- 30295185 TI - Metabolomics of exhaled breath condensate by nuclear magnetic resonance spectroscopy and mass spectrometry: a methodological approach. AB - Respiratory diseases present a very high prevalence in the general population, with an increase in morbidity, mortality and health-care expenses worldwide. They are complex and heterogeneous pathologies that may present different pathological facets in different subjects, often with personal evolution. Therefore, there is a need to identify patients with similar characteristics, prognosis or treatment, defining the so-called phenotype, but also to mark specific differences within each phenotype, defining the endotypes. Biomarkers are very useful to study respiratory phenotypes and endotypes. Metabolomics, one of the recently introduced "omics", is becoming a leading technique for biomarker discovery. For the airways, metabolomics appears to be well suited as the respiratory tract offers a natural matrix, the exhaled breath condensate (EBC), in which several biomarkers can be measured. In this review, we will discuss the main methodological issues related to the application of nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) to EBC metabolomics for investigating respiratory diseases. PMID- 30295186 TI - Novel technologies for dipeptide drugs design and their implantation. AB - The article is an overview of author's data obtained in the framework of the project "The Creation of dipeptide preparations" at the V.V. Zakusov Institute of Pharmacology, Moscow, Russia. Advantages of dipeptides over longer peptides consist in that they are orally active owing to higher stability and ability to penetrate biological barriers due to presence of specific ATP-dependent transporters in enterocytes and blood-brain barrier. Two original approaches for dipeptide drugs design have been developed. Both of them are based on the idea of a leading role of central dipeptide fragment of the peptide chain beta-turn in the peptide-receptor interaction. The first approach, named "peptide drug-based design" represents the transformation of known nonpeptide drug into its dipeptide topological analog. The latter usually corresponds to a beta-turn of some regulatory peptide. The second approach represents the design of tripeptoide mimetic of the beta-turn of regulatory peptide or protein. The results of the studies, which led to the discovery of endogenous prototypes of the known non peptide drugs piracetam and sulpiride, are presented herein. The paper discusses the process, based on the above-mentioned principles, that was used in designing of nontoxic, orally available, highly effective dipeptide drugs: nootropic noopept, dipeptide analog of piracetam; antipsychotic dilept, neurotensin tripeptoid analog; selective anxiolytic GB-115, tripeptoid analog of CCK-4, and potential neuroprotector GK-2, homodimeric dipeptide analog of NGF. PMID- 30295187 TI - Is very low LDL-C harmful? AB - BACKGROUND: Low-density lipoprotein cholesterol (LDL-C) is a major cardiovascular (CV) risk factor. Accumulating evidence supports a linear association between LDL C levels and CV risk. However, the lower limit of LDL-C that might offer CV benefits without any safety concerns is still a topic of debate. OBJECTIVE: The purpose of this review is to present the safety of reducing LDL-C to low levels as it comes from major lipid-lowering drug studies, and to discuss data on several safety events that have been associated with low LDL-C levels. METHODS: A comprehensive literature search was performed to identify available data from clinical studies evaluating the association of low LDL-C with safety outcomes. RESULTS: Several large trials have evaluated the safety or reducing LDL-C to levels lower than 50 mg/dl or even lower than 25 mg/dl, more commonly with the use of combination of statins with ezetimibe or proprotein convertase subtilisin kexin 9 inhibitors. In almost all trials, CV benefits were observed with LDL-C levels of 50 mg/dl or less compared with higher levels. In terms of safety, reduction of LDL-C to such levels was not associated with any significant adverse event. Of importance, cancer and hemorrhagic stroke incidences were not increased in patients attaining LDL-C lower than 40-50 mg/dl. Data regarding the impact of lowering LDL-C with neurocognitive disorders are contradictory; nevertheless, most studies stand in favor of neurocognitive safety with LDL-C reductions to low levels. CONCLUSION: Achieving an LDL-C of 40-50 mg/dl seems to be safe, and importantly might offer CV beneficial effects. Data for attaining levels below 25 mg/dl is limited, however in favor of such reductions. PMID- 30295188 TI - Identification and characterization of genes in curcuminoid pathway of Curcuma zedoaria Roscoe. AB - BACKGROUND: Curcuminoid genes have an important role in the biosynthesis of curcumin, a valuable bioactive compound, in Curcuma species. However, there have not been any reports of these genes in Curcuma zedoaria. OBJECTIVE: The present work reports on the isolation of genes encoding enzymes in curcuminoid metabolic pathway and their expression in C. zedoaria. METHOD: The primers were designed from untranslation regions of DCS, CURS1, CURS2 and CURS3 genes which involve in curcuminoid biosynthesis in C. longa to isolate the corresponding full-length genes in C. zedoaria. RT-PCR amplification and HPLC analysis used to estimate expression of genes and biosynthesis of curcumin in both rhizome and callus. RESULTS: The results showed that all four genes from C. zedoaria (named CzDCS, CzCURS1, CzCURS2 and CzCURS3) and C. longa have a high identity (approximately 99%) and lengths of genes from C. zedoaria are 1382, 1240, 1288 and 1265 nu, respectively. CzCURS1, 2 and 3 genes have one intron while CzDCS has two introns. RT -PCR amplification indicated curcuminoid genes have expressed mRNA in rhizome and callus of C. zedoaria. Curcumin, a major component of curcuminoids, was also found in callus by HPLC analysis. CONCLUSION: The sequence information of DCS and CURS1-3 genes in C. zedoaria will be very valuable for subsequent study on the effects of elicitors on the transcription of genes involving in curcuminoid biosynthesis pathway. PMID- 30295189 TI - EZH2 RIP-seq Identifies Tissue-specific Long Non-coding RNAs. AB - BACKGROUND: Polycomb Repressive Complex 2 (PRC2) catalyzes histone methylation at H3 Lys27, and plays crucial roles during development and diseases in numerous systems. Its catalytic subunit EZH2 represents a key nuclear target for long non coding RNAs (lncRNAs) that emerging to be a novel class of epigenetic regulator and participate in diverse cellular processes. LncRNAs are characterized by high tissue-specificity; however, little is known about the tissue profile of the EZH2 interacting lncRNAs. OBJECTIVE: Here we performed a global screening for EZH2 binding lncRNAs in tissues including brain, lung, heart, liver, kidney, intestine, spleen, testis, muscle and blood by combining RNA immuno- precipitation and RNA sequencing. We identified 1328 EZH2-binding lncRNAs, among which 470 were shared in at least two tissues while 858 were only detected in single tissue. An RNA motif with specific secondary structure was identified in a number of lncRNAs, albeit not in all EZH2-binding lncRNAs. The EZH2-binding lncRNAs fell into four categories including intergenic lncRNA, antisense lncRNA, intron-related lncRNA and promoter-related lncRNA, suggesting diverse regulations of both cis and trans-mechanisms. A promoter-related lncRNA Hnf1aos1 bound to EZH2 specifically in the liver, a feature same as its paired coding gene Hnf1a, further confirming the validity of our study. In addition to the well known EZH2 binding lncRNAs like Kcnq1ot1, Gas5, Meg3, Hotair and Malat1, majority of the lncRNAs were firstly reported to be associated with EZH2. CONCLUSION: Our findings provide a profiling view of the EZH2-interacting lncRNAs across different tissues, and suggest critical roles of lncRNAs during cell differentiation and maturation. PMID- 30295190 TI - Utilization of Analytical Omics Tools in the Molecular Diagnostics of Multiple Myeloma. AB - Multiple myeloma (MM) is characterized by the clonal proliferation of malignant plasma B-lymphocytes and even as of today, it is an incurable disease. MM accounts for approximately 10% of all hematologic cancers. Its molecular pathogenesis is poorly understood, but the bone marrow microenvironment of tumor cells and genetic factors have apparent roles in the process. Accurate diagnosis is important to properly identify and stratify the disease, however, MM identification steps are time-consuming and expensive. Thus, development of early molecular diagnostic methods is of high importance in order to start proper therapies as early in the disease progression as possible, given the nature of the poor survival rates/remission periods. Molecular diagnostics via analytical omics represents one of the promising toolsets to speed up the diagnostic process. In this paper, we critically review the utilization of state of the art, high sensitivity analytical omics approaches (genomics, proteomics, metabolomics, lipidomics and glycomics) in MM diagnostics at the molecular level. PMID- 30295191 TI - Synthesis, 2D-QSAR studies and Biological Evaluation of Quinazoline Derivatives as potent Anti-Trypanosoma cruzi Agents. AB - BACKGROUND: Chagas disease affects about 7 million people worldwide. Only two drugs are currently available for the treatment for this parasite disease, namely, benznidazol (Bzn) and nifurtimox (Nfx). Both drugs have limited curative power in the chronic phase of the disease. Therefore, continuous research is an urgent need so as to discover novel therapeutic alternatives. OBJECTIVE: The development of safer and more efficient therapeutic anti-T. cruzi drugs continues to be a major goal in trypanocidal chemotherapy. METHOD: Synthesis, 2D-QSAR and drug-like physicochemical properties of a set of quinazolinone and quinazoline derivatives were studied as trypanocidal agents. All compounds were screened in vitro against Trypanosoma cruzi (Tulahuen strain, Tul 2 stock) epimastigotes and bloodstream trypomastigotes. RESULTS: Out of 34 compounds synthesized and tested, six compounds (5a, 5b, 9b, 9h, 13f and 13p) displayed significant activity against both epimastigotes and tripomastigotes, without exerting toxicity on Vero cells. CONCLUSION: The antiprotozoal activity of these quinazolinone and quinazoline derivatives represents an interesting starting point for a medicinal chemistry program aiming at the development of novel chemotherapies for Chagas disease. PMID- 30295192 TI - Phenolic Imidazole Derivatives with Dual Antioxidant/Antifungal Activity: Synthesis and Structure-Activity Relationship. AB - BACKGROUND: Previous publications show that the addition of a phenolic antioxidant to an antifungal agent, considerably enhances the antifungal activity. OBJECTIVE: Synthesis of novel compounds combining phenolic units with linear or cyclic nitrogen-containing organic molecules with antioxidant/antifungal activity using methodologies previously developed in the group. METHODS: Several N-[1,2-dicyano-2-(arylidenamino)vinyl]-O alkylformamidoximes 3 were synthesized and cyclized to 4,5-dicyano-N-(N' alcoxyformimidoyl)-2-arylimidazoles 4 upon reflux in DMF, in the presence of manganese dioxide or to 6-cyano-8-arylpurines 5 when the reagent was refluxed in acetonitrile with an excess of triethylamine. These compounds were tested for their antioxidant activity by cyclic voltammetry, DPPH radical (DPPH*) assay and deoxyribose degradation assay. The minimum inhibitory concentration (MIC) of all compounds was evaluated against two yeast species, Saccharomyces cerevisiae and Candida albicans, and against bacteria Bacillus subtilis (Gram positive) and Escherichia coli (Gram negative). Their cytotoxicity was evaluated in fibroblasts. RESULTS: Among the synthetised compounds, five presented higher antioxidant activity than reference antioxidant Trolox and from these compounds, four presented antifungal activity without toxic effects in fibroblasts and bacteria. CONCLUSION: Four novel compounds presented dual antioxidant/antifungal activity at concentrations that are not toxic to bacteria and fibroblasts. The active molecules can be used as an inspiration for further studies in this area. PMID- 30295193 TI - Role of Porous Carriers in the Biopharmaceutical Performance of Solid Self microemulsion Preconcentrates of Canagliflozin1. AB - OBJECTIVE: The aim of the present investigation entails the development of solid SMEDDS for improving the oral bioavailability of canagliflozin using porous carriers. The previous patent (WO2017046730A1) was based on enhanced of solubility of canagliflozin through co-crystal formation. METHODS: Preconcentrates were prepared by employing Lauroglycol (80 mg), Tween 80 (300 mg) and Transcutol P (120 mg) and successfully adsorbed onto various hydrophilic and hydrophobic carriers. The prepared solid SMEDDS were characterized for various parameters to determine the optimized formulation. In vitro, ex vivo and in vivo studies were carried out to determine drug release kinetics, permeation and absorption rate, respectively. Stability of the formulation was investigated at 45 degrees C/75% RH. RESULTS: The solid preconcentrates prepared with hydrophobic carriers exhibited desired attributes in uniform range. Neusilin adsorbed solid SMEDDS (S(N)SMEDDS) portrayed enhanced amorphization in XRD and DSC studies and found to be physically compatible in FTIR studies. SEM revealed colloidal particles having spherical morphology with negligible aggregation. Ex vivo permeation rate of the drug across excised intestinal segments (duodenum, jejunum, ileum and colon) was observed to be 3.72, 5.85, 4.51 and 3.0-fold, respectively, as compared to pure drug. TEM of reconstituted SMEDDS indicated nano-sized globules with negligible coalescence. Enhanced in vitro dissolution rate of optimized solid SMEDDS manifested in bioavailability enhancement of 167.54% and 188.98 %, as compared to pure drug and marketed product. These studies further substantiate the lymphatic uptake of SMEDDS through chylomicron flow blocking approach. Establishment of Level A IVIVC showed uniform correlation between the in vitro dissolution efficiency and in vivo pharmacokinetic parameters. CONCLUSION: The present investigation reveals immense potential of solid SMEDDS in augmenting the oral bioavailability profile of poorly water soluble drug canagliflozin.

AB - OBJECTIVE: to determine the predictors of obstructive sleep apnea syndrome (OSAS) basing on clinical examination, results of night pulse oximetry, daily dynamics of heart rate and blood pressure (BP) in men with newly diagnosed arterial hypertension (AH). MATERIALS AND METHODS: Men (n=197, mean age 40.1 +/- 8.4 years) with newly diagnosed AH of mild (63%), moderate (26%), and severe (11%) degree. OSAS (Apnea-Hypopnea Index [AHI] >=5 events per hour) was diagnosed in 156 patients (79%). Patients were divided into four groups depending on the AHI. The control group consisted of 31 men without AH and OSAS. Examination included standard clinical, laboratory and instrumental methods, as well as assessment of daytime sleepiness by the Epworth scale. Diagnostics of OSAS and 24-hour BP monitoring were performed on a portable multifunctional recorder. The duration of sleep was determined from the actigraphy data. Statistical analysis was carried out using descriptive statistics, correlation, regression and Receiver Operating Characteristic (ROC) curve analysis. RESULTS: In the studied sample of patients with AH prevailed individuals with central obesity and dyslipidemia. Mean estimate of daytime sleepiness assessed by the Epworth Sleepiness Scale was 7.8+/ 4.8 points. Of 156 patients with OSAS, its moderate and severe degree (AHI >=15) was diagnosed in 64%. Predictors of the presence of OSAS were the following: body mass index (odds ratio [OR] 1.13, 95% confidence interval [CI] 1.05-1.22, p.

AB - OBJECTIVE: To assess dynamics of the quality of life (QOL) in patients of the older age group of with initial aortic stenosis in 1, 3, and 5 years after replacement of the aortic valve (AV) with biological or mechanical prosthesis. MATERIALS AND METHODS: QOL was assessed in 282 patients who underwent aortic valve replacement with a biological or mechanical prosthesis. Criterion for inclusion in this retrospective single-center study was primary and elective nature of the operation. Patients with repeated interventions (early postoperative resternotomy, reosteosynthesis, repeat aortic valve surgery) were not included. Using the method of Propensity Score Matching, we distributed 151 patients in whom the long-term results of AV replacement were analyzed according to age, gender, body mass index into groups of AV replacement with biological (group 1, n=74) and mechanical (group 2, n=77) prosthesis. RESULTS: In the early period after operation, there was no significant difference between groups in parameters of quality of life. During the observation period up to 3 years significant increases of parameters bodily pain (BP), vitality (VT), and mental health (MH) occurred in patients with biological prostheses, while physical functioning (PF) was higher in patients with mechanical prostheses. At follow-up to 5 years, indicators such as BP and role emotional functioning (RE) became higher in patients with mechanical prostheses. According to the conducted regression analysis the type of prosthesis affected the quality of life. CONCLUSIONS: 1) AV replacement with mechanical prostheses was associated with lowering of the physical component of health by 81.1%, and of the mental health component - by 56.6% per month; 2) significant difference in QOL between groups of patients with mechanical and biological prostheses could be detected only in 3 years after the operation: parameters BP, VT and MH were significantly higher in patients with biological prostheses, while PF was higher in patients with mechanical prostheses; 3) in the longer observation period (up to 5 years) parameters BP and RE became higher in patients with mechanical prostheses.

AB - OBJECTIVE: to establish associations of candidate genes ACE, AGT, AGTR1, ADRB1, ADRA2B, MTHFR and NOS3 polymorphisms with left ventricular myocardial hypertrophy (LVH) in patients with arterial hypertension (AH) among the indigenous (the Shors) and non-indigenous population of Mountain Shoria. MATERIALS AND METHODS: We examined 788 people in a clinical and epidemiological study of compactly living population in the remote areas of Mountain Shoria, located in the south of Western Siberia (468 members of indigenous ethnic group [the Shors], 320 members of non-indigenous ethnic group [90% Caucasian]). Diagnosis of AH was set in accordance with recommendations of Society of Cardiology of the Russian Federation/Medical Society of the Russian Federation on the Problem of Arterial Hypertension (RMOAG) (2010). Assessment of the structural and functional state of myocardium in patients with AH (n=201 among Shors and 158 among non-indigenous residents) was made by echocardiography. The polymorphisms of genes ACE (I/D, rs 4340), AGT (c.803T>C, rs699), AGTR1 (A1166S, rs5186), ADRB1 (s.145A>G, Ser49Gly, rs1801252), ADRA2B (I/D, rs 28365031), MTHFR (c.677S>T, Ala222Val, rs1801133) and NOS3 (VNTR, 4b/4a) were tested by PCR. RESULTS: Among patients with AH LVH occurred more often within the indigenous (Shor) than in non-indigenous (non Shor) ethnic group (51.5 vs 42.2%, respectively, p=0.034). The frequency of homozygous genotype I/I of the ACE gene among AH patients with LVH in the Shor group was higher than in the non-Shor group (41.2 vs 19.3%, p=0.004). The prevalence of mutant genotype A/A of the ADRB1 gene was lower in the Shor compared to non-Shor group (53.6 vs 75.0%, p=0.014). The percentage of the carriers of prognostically favorable genotype 4b/4b of the NOS3 gene was higher in Shor than in non-Shor group (71.9 vs 52.7%, p=0.018), while the percentage of homozygous genotype 4a/4a carriers in the Shor group was lower (2.1% vs 18.2%, p=0.008). CONCLUSION: The following studied genes were found to be associated of with LVH: in the Shor cohort - the MTHFR gene (log additive model of inheritance), the A/G genotype of the ADRB1 gene (among people with normal body weight), the I/D genotype of the ACE gene (among men); in the non-indigenous cohort - D/D genotype of the ACE gene (the codominant model of inheritance), the NOS3 gene (the log additive model of inheritance).

AB - BACKGROUND: More than 10 years passed since conduction of the first clinical epidemiological study of prevalence of psychosocial risk factors (PSRF) in patients with arterial hypertension (AH) an/or ischemic heart disease in Russian Federation. PURPOSE: to assess current prevalence of PSRF in patients with AH/CHD and their relationship with traditional risk factors. MATERIALS AND METHODS: Patients with verified AH and/or CHD aged >=55 years were included into this cross-sectional study in 30 cities of Russia representing 7 federal districts according to the following procedure. In each city we selected 2-5 federal clinics - providers of primary medical care; in each of these clinics we at random invited 2-5 physicians to take part in this study. Each of these physicians for 1-2 days included 10 consecutive patients with AH and/or CHD. Information collected from patients comprised social demographic and clinical characteristics, risk factors, adherence to therapy; Hospital Anxiety and Depression Scale (HADS) was applied for detection of symptoms of anxiety and depression. Obtained information was used for analysis of prevalence of cardiovascular risk factors and their association with symptoms of depression and anxiety in a framework of Pearson linear and Kendall rank correlation analysis. RESULTS: Symptoms of anxiety of various severity (HADS-A>=7) were detected in 42.2% of patients with AH and/or CHD, in 25.5% they were clinically significant (HADS-A>=11). Symptoms of depression of various severity (HADS-D >=7) were detected in 42.5% of patients with AH and/or CHD, in 16.3% they were clinically significant (HADS-D>=11). We also observed several significant associations of symptoms of depression and anxiety with traditional cardiovascular risk factors: low level of physical activity, elevated systolic and diastolic arterial pressure, level of total cholesterol, abdominal obesity; some unhealthy nutritional habits. CONCLUSIONS: Prevalence of symptoms of anxiety and depression was found to be high among ambulatory patients with AH and/or CHD. However, in this study it was lower compared with that reported by previous studies in Russia. PMID- 30295200 TI - [Metabolomic Profiling of Patients With Cardiovascular Diseases]. AB - Cardiovascular diseases (CVD) are the main cause of death worldwide. A broad study of the pathogenetic mechanisms of the CVD onset and progression has led to understanding of the importance of endothelial dysfunction (ED) in these processes. During recent years intensive work has been conducted in the direction of searching for markers of ED. Metabolomics is an intensively advancing approach to early diagnostics of diseases. Metabolomic analysis based on mass spectrometry allows to study complete metabolic profiles and their deviations resulting from changes in expression of genes and RNA, protein activity, or environmental factors. Metabolomic analysis has already demonstrated significant results in the solving of different scientific and clinical problems. It appears to be a promising method for detecting early biomarkers of CVD. Various aspects of application of metabolomic profiling in the field of cardiovascular diseases are discussed in this article.

AB - : The article deals with the dynamics of echocardioscopy indices during 1.5 years in a patient who underwent an acute myocardial infarction (MI). Two months after the MI left ventricular (LV) end-diastolic size and LV volume were 61 mm and 190 ml, respectively; LV ejection fraction (EF) was 42%. At the background of maximal possible doses of ramipril, bisoprolol, and selective antagonist of aldosterone receptors eplerenone, and after revascularization, within eight months LV end diastolic size decreased down to 57 mm, LV volume - to 158 ml, and LVEF increased up to 51%. There was no change of potassium and creatinine blood serum levels. The situation changed dramatically after addition to ongoing therapy because of exacerbation of chronic osteochondrosis of ketoprofen 100, meloxicam 15 and tolperisone (Mydocalm) 450 mg/day. The patient noted an increase in dyspnea during walking, a decrease in exercise tolerance. LVEF fell to 36%, LV size increased up to values registered in 2 months after MI. There were no signs of overt fluid retention (no gain of weight, lower limbs edema, lung congestion on X ray, hepatomegaly at ultrasound examination). In 4 months after addition to therapy of a loop diuretic torasemide (5 mg) the cardio-hemodynamic parameters almost returned to values prior to administration of anti-inflammatory drugs. CONCLUSION: Loop diuretic (such as torasemide) can be recommended for elimination of negative consequences of the use of nonsteroidal anti-inflammatory drugs in patients with chronic heart failure. PMID- 30295206 TI - Parent-Reported Child Reactions to the September 11, 2001 World Trade Center Attacks (New York USA) in Relation to Parent Post-Disaster Psychopathology Three Years After the Event. AB - : IntroductionParents are a primary support for children following disasters, even though they face numerous challenges in addressing the physical and social consequences of an event. Parents who are directly exposed to a disaster and those who develop psychiatric disorders post-event are likely to be especially challenged and may be limited in their ability to support their children. This Brief Report describes a pilot study of survivors of the September 11, 2001 World Trade Center (New York USA) attacks who reported their own psychosocial consequences and the reactions of their children three years post event.HypothesesThe primary hypothesis of the study was that children's September 11th reactions would be associated with their parents' psychiatric status. Secondary hypotheses were that the children's disaster reactions would be associated with direct exposure to the disaster in children and/or their parents, parent-child separation due to the disaster, and disaster-related school absence. METHODS: Approximately three years after the 2001 World Trade Center attacks, 116 parents recruited from disaster-affected or disaster-related organizations were assessed using structured diagnostic interviews and queried about their children's (188 youths, aged three to 17 years at the time of the attacks) posttraumatic stress symptoms and behavioral changes. RESULTS: Almost one-half of the parents had a post-disaster psychiatric disorder, including major depression in 27% and disaster-related posttraumatic stress disorder (PTSD) in 11%. More than three-fourths of the children had at least one disaster-related posttraumatic stress symptom, and more than one-half experienced at least one post-disaster behavior change. A minority of the children were reported to have increased school behavior problems or a decline in their grades. Key correlates of children's disaster-related posttraumatic stress symptoms and post-disaster behavior changes were parent-child separation due to the disaster and parental post-disaster psychiatric disorders. CONCLUSION: Because parents provide primary caretaking and support for children post-disaster, addressing the needs of parents is critical to their ability to assist their children. Reducing parents' symptoms should increase their emotional availability and enhance their ability to address the needs of their children. Given the challenges in providing disaster interventions directly to children, especially when resources are limited, addressing parent psychopathology and distress (even in the absence of focusing on children's symptoms) may benefit children.

AB - Scarce research has examined stress responsivity among Latino youths, and no studies have focused on the role of acculturation in shaping cortisol stress response in this population. This study assessed Mexican American adolescents' Mexican and Anglo cultural orientations and examined prospective associations between their patterns of bicultural orientation and hypothalamic-pituitary adrenal cortisol reactivity to an adapted Trier Social Stress Test. The sample included 264 youths from a longitudinal birth cohort study who completed the Trier Social Stress Test and provided saliva samples at age 14. The youths completed assessments of cultural orientation at age 12, and family conflict and familism at age 14. Analyses testing the interactive effects of Anglo and Mexican orientation showed significant associations with cortisol responsivity, including the reactivity slope, peak levels, and recovery, but these associations were not mediated by family conflict nor familism values. Findings revealed that bicultural youth (high on both Anglo and Mexican orientations) showed an expected pattern of high cortisol responsivity, which may be adaptive in the context of a strong acute stressor, whereas individuals endorsing only high levels of Anglo orientation had a blunted cortisol response. Findings are discussed in relation to research on biculturalism and the trade-offs and potential recalibration of a contextually responsive hypothalamic-pituitary-adrenal axis for acculturating adolescents. PMID- 30295208 TI - Mood stabilisers and risk of stroke in bipolar disorder. AB - BACKGROUND: Research on the risk of stroke following the use of mood stabilisers specific to patients with bipolar disorder is limited.AimsIn this study, we investigated the risk of stroke following the exposure to mood stabilisers in patients with bipolar disorder. METHOD: Data for this nationwide population-based study were derived from the Taiwan National Health Insurance Research Database. Among a retrospective cohort of patients with bipolar disorder (n = 19 433), 609 new-onset cases of stroke were identified from 1999 to 2012. A case-crossover study design utilising 14-day windows was applied to assess the acute exposure effect of individual mood stabilisers on the risk of ischaemic, haemorrhagic and other types of stroke in patients with bipolar disorder. RESULTS: Mood stabilisers as a group were significantly associated with the increased risk of stroke in patients with bipolar disorder (adjusted risk ratio, 1.26; P = 0.041). Among individual mood stabilisers, acute exposure to carbamazepine had the highest risk of stroke (adjusted risk ratio, 1.68; P = 0.018), particularly the ischaemic type (adjusted risk ratio, 1.81; P = 0.037). In addition, acute exposure to valproic acid elevated the risk of haemorrhagic stroke (adjusted risk ratio, 1.76; P = 0.022). In contrast, acute exposure to lithium and lamotrigine did not significantly increase the risk of any type of stroke. CONCLUSIONS: Use of carbamazepine and valproic acid, but not lithium and lamotrigine, is associated with increased risk of stroke in patients with bipolar disorder.Declaration of interestNone.

AB - The objective of this paper was to study nutritional status and growth, as measured by height and weight, over the life course and their connection with chronic diseases in Guatemala, a country with high levels of child undernutrition and adult overnutrition, using data from the Institute of Nutrition of Central America and Panama (INCAP) Nutrition Trial Cohort study. The study sample comprised a birth cohort of 1570 individuals who had data in the original 1969 1977 survey as well as the 2002-2004 follow-up, allowing for an analysis of the nutritional transition from childhood to adulthood. The associations between childhood and adulthood anthropometrics were analysed, and the links of these with chronic disease indicators were assessed using multiple regression analysis and structural equation modelling. Moving upwards in nutritional status from childhood to adulthood was observed frequently in the study population. Unlike sex and place of residence, early anthropometrics were not generally found to be associated with adult body mass index (BMI). However, direct relationships were found between childhood nutritional status and growth and adulthood high-density lipoprotein (HDL) cholesterol, triglycerides and fasting blood glucose. Furthermore, these relationships were not mediated by BMI. The findings were not sensitive to the metric of childhood anthropometrics, as the use of length-for age, weight-for-age and weight-for-length all resulted in similar conclusions. These relationships demonstrate the importance of early childhood conditions for later-life outcomes. However, the lack of such relationships for blood pressure suggests that the biological links between childhood anthropometrics and various chronic diseases might vary. PMID- 30295211 TI - Primary care chaplaincy: an intervention for complex presentation. AB - : AimTo determine the responsiveness of primary care chaplaincy (PCC) to the current variety of presenting symptoms seen in primary care. This was done with a focus on complex and undifferentiated illness. BACKGROUND: Current presentations to primary care are often complex, undifferentiated and display risk factors for social isolation and loneliness. These are frequently associated with loss of well-being and spiritual issues. PCC provides holistic care for such patients but its efficacy is unknown in presentations representative of such issues. There is therefore a need to assess the characteristics of those attending PCC. The effectiveness of PCC relative to the type and number of presenting symptoms should also be analysed whilst evaluating impact on GP workload. METHODS: This was a retrospective observational study based on routinely collected data. In total, 164 patients attended PCC; 75 were co-prescribed antidepressants (AD) and 89 were not (No-AD). Pre- and post-PCC well-being was assessed by the Warwick Edinburgh mental well-being score. Presenting issue(s) data were collected on a separate questionnaire. GP appointment utilisation was measured for three months pre- and post-PCC.FindingsThose displaying undifferentiated illness and risk factors for social isolation and loneliness accessed PCC. PCC (No-AD) was associated with a clinically meaningful and statistically significant improvement in well-being in all presenting issues. This effect was maintained in those with multiple presenting issues. PCC was associated with a reduction in GP appointment utilisation in those not co-prescribed AD.

AB - The aim of the present study was to evaluate the potential for diagnosis of fatty liver by means of ultrasonographic measurement of liver and perivisceral adipose tissue as an alternative to blood indicators of lipomobilization and liver biopsy in periparturient high-yielding dairy cows. Thirty cows were enrolled and divided into two groups. The evaluation of body condition score (BCS), non-esterified fatty acids (NEFA), beta-hydroxybutyrate (BHB), liver and perivisceral adipose tissue ultrasonographic measurement and histological liver lipid content (GdL) was performed at 15 +/- 5 d prepartum (T0), 10 +/- 2 d postpartum (T1), 30 +/- 2 d postpartum (T2) and 50 +/- 2 d postpartum (T3). Mesenteric fat thickness (the thickness of the perivascular adipose tissue) measured on ultrasound was shown to be an independent determinant of fatty liver. The cut-off of the ultrasonographic evaluation of the liver may be useful as a first and practical approach in identifying fatty liver. In conclusion, a non-invasive and reliable diagnostic method for predicting the risk of fatty liver in high yielding dairy cows has been demonstrated.

AB - BACKGROUND: Otolithic function is poorly understood, but vestibular-evoked myogenic potential testing has allowed the documentation of pathology in patients who complain of imbalance. METHODS: Seventy-four patients with traumatic and non traumatic vestibular disease were sequentially assessed at a tertiary referral neuro-otology unit in a teaching hospital. A detailed history of all patients was taken and standard vestibular assessment was conducted using the technique described in the companion paper. The results of both groups of patients were analysed and the rate of abnormalities was assessed. RESULTS: There was a high rate of abnormalities, including bilateral pathology, in a significant number of patients. Many patients in both groups inexplicably failed to recover. CONCLUSION: Vestibular-evoked myogenic potentials are helpful in documenting pathology, including bilateral pathology, which is outlined in the literature as being exceedingly difficult to compensate for. PMID- 30295214 TI - Trends in marketing foods to children in Slovenian magazines: a content analysis. AB - OBJECTIVE: Food marketing is an important factor influencing children's food preferences. In Slovenia the use of magazines is widespread among children. We investigated food advertising in children's and teens' magazines (CTM) in 2013 and 2017. The penetration of food advertising was compared with magazines targeting the adult population. DESIGN: A repeated cross-sectional study. Magazines were searched for branded food references (BFR). All BFR were categorised and evaluated using the WHO Europe nutrient profile model. SETTING: Slovenia. SUBJECTS: All issues of CTM and a selected sample of issues of adult targeting magazines and newspapers published in Slovenia in 2013 and 2017. RESULTS: One hundred and seventy-five issues of CTM (ninety-two in 2013, eighty three in 2017) and 675 issues of adult-targeted magazines and newspapers were analysed (345 in 2013, 330 in 2017). In 2017, food advertising in CTM dropped notably but the opposite was found for adult-targeted magazines. Regular advertisements dominated in 2017 in CTM, while in 2013, 83 % of BFR types were games/puzzles, competitions and product placements. Chocolate and confectionery were the most advertised in CTM and food supplements in adults' magazines. Most foods in CTM were classed as 'not permitted' in both years (98 % in 2013 and 100 % in 2017). CONCLUSIONS: The advertisements in CTM still mostly refer to unhealthy foods. The extent of food advertising has dropped considerably since 2013. On the contrary, food advertising in printed media targeting adults has increased, chiefly referring to food supplements and foods that do not pass the WHO Europe nutrient profile model criteria. PMID- 30295213 TI - Biocultural determinants of overweight and obesity in the context of nutrition transition in Senegal: a holistic anthropological approach. AB - Senegal is experiencing a rising obesity epidemic, due to the nutrition transition occurring in most African countries, and driven by sedentary behaviour and high-calorie dietary intake. In addition, the anthropological local drivers of the social valorization of processed high-calorie food and large body sizes could expose the population to obesity risk. This study aimed to determine the impact of these biocultural factors on the nutritional status of Senegalese adults. A mixed methods approach was used, including qualitative and quantitative studies. Between 2011 and 2013, fourteen focus group discussions (n=84) and a cross-sectional quantitative survey (n=313 women; n=284 men) of adults in three different socio-ecological areas of Senegal (rural: n=204; suburban: n=206; urban: n=187) were conducted. Dietary intake (Dietary Diversity Scores), physical activity (International Physical Activity Questionnaire), body weight norms (Body Size Scale), weight and health statuses (anthropometric measures and blood pressure) were measured. Middle-aged and older Senegalese women were found to value overweight/obesity more than younger Senegalese in all regions. In addition, young urban/suburban adults had a tendency for daily snacking whilst urban/suburban adults tended to be less physically active and had higher anthropometric means. A binary logistic regression model showed that being female, older, living in urban/suburban areas and valuing larger body size were independently associated with being overweight/obese, but not high-calorie diet. Univariate analyses showed that lower physical activity and higher socioeconomic status were associated with being overweight/obese. Finally, overweight/obesity, which is low in men, is associated with hypertension in the total sample. The nutrition transition is currently underway in Senegal's urban/suburban areas, with older women being more affected. Since several specific biocultural factors jointly contribute to this phenomenon, the study's findings suggest the need for local public health interventions that target women and which account for the anthropological specificities of the Senegalese population. PMID- 30295215 TI - Drug-drug interactions and clinical considerations with co-administration of antiretrovirals and psychotropic drugs. AB - Psychotropic medications are frequently co-prescribed with antiretroviral therapy (ART), owing to a high prevalence of psychiatric illness within the population living with HIV, as well as a 7-fold increased risk of HIV infection among patients with psychiatric illness. While ART has been notoriously associated with a multitude of pharmacokinetic drug interactions involving the cytochrome P450 enzyme system, the magnitude and clinical impact of these interactions with psychotropics may range from negligible effects on plasma concentrations to life threatening torsades de pointes or respiratory depression. This comprehensive review summarizes the currently available information regarding drug-drug interactions between antiretrovirals and pharmacologic agents utilized in the treatment of psychiatric disorders-antidepressants, stimulants, antipsychotics, anxiolytics, mood stabilizers, and treatments for opioid use disorder and alcohol use disorder-and provides recommendations for their management. Additionally, overlapping toxicities between antiretrovirals and the psychotropic classes are highlighted. Knowledge of the interaction and adverse effect potential of specific antiretrovirals and psychotropics will allow clinicians to make informed prescribing decisions to better promote the health and wellness of this high-risk population. PMID- 30295216 TI - Mental health outcomes at the end of the British involvement in the Iraq and Afghanistan conflicts: a cohort study. AB - BACKGROUND: Little is known about the prevalence of mental health outcomes in UK personnel at the end of the British involvement in the Iraq and Afghanistan conflicts.AimsWe examined the prevalence of mental disorders and alcohol misuse, whether this differed between serving and ex-serving regular personnel and by deployment status. METHOD: This is the third phase of a military cohort study (2014-2016; n = 8093). The sample was based on participants from previous phases (2004-2006 and 2007-2009) and a new randomly selected sample of those who had joined the UK armed forces since 2009. RESULTS: The prevalence was 6.2% for probable post-traumatic stress disorder, 21.9% for common mental disorders and 10.0% for alcohol misuse. Deployment to Iraq or Afghanistan and a combat role during deployment were associated with significantly worse mental health outcomes and alcohol misuse in ex-serving regular personnel but not in currently serving regular personnel. CONCLUSIONS: The findings highlight an increasing prevalence of post-traumatic stress disorder and a lowering prevalence of alcohol misuse compared with our previous findings and stresses the importance of continued surveillance during service and beyond.

PMID- 30295218 TI - Methotrexate for the treatment of unruptured tubal ectopic pregnancy. AB - CLINICIAN'S CAPSULE What is known about the topic? Methotrexate is widely accepted as first-line treatment of non-ruptured ectopic pregnancy and may be considered for women with a suspected ectopic pregnancy. What did this study ask? What are the outcomes of pregnant women with suspected ectopic pregnancy who received methotrexate as first-line treatment? What did this study find? Of patients treated with methotrexate, 18% went on to require surgical management, with 11.2% having ruptured on surgical evaluation. Why does this study matter to clinicians? Emergency department (ED) clinicians must be aware of the risk of methotrexate failure and have a high index of suspicion for patients returning to the ED.

AB - In addition to being associated with a higher risk of complications during pregnancy, twinning may also be a proxy for altered hormonal exposure for mothers and twin offspring, with implications for their health later in life. We compared maternal and fetal steroid hormone and insulin-like growth factor concentrations between singleton (n=62) and twin (n=41) pregnancies. Maternal concentrations of androgens, estrogens, insulin-like growth factor (IGF)-1, IGF-binding protein (BP)-3 and prolactin were quantified during the third trimester and at delivery, as well as in the fetal circulation at birth. Geometric means accounting for gestational age were calculated for hormone concentrations and compared between matched twin and singleton pregnancies. Most maternal hormone concentrations were modestly higher in twin than in singleton pregnancies in the third trimester (ranging from 8.3% for IGF-1 to 17.1% for estradiol) and at delivery (ranging from 11.1% for IGFBP-3 to 15.2% for estriol). Cord serum hormones were generally similar in twin and singleton pregnancies, except for IGFBP-3, which was 200% lower in twins. The modest differences in maternal hormones in late gestation seem unlikely to explain alterations in hormonally related disease risk in mothers of twins compared with singletons. The large deficit of IGFBP-3 in the fetal circulation of twins at birth may allow for sufficient concentrations of IGF-2 for growth and development in an environment of shared nutritional resources.

AB - ABSTRACTEye-tracking devices are able to capture eye movements, which are further characterized by fixations. The application of eye tracking in a trauma setting has not been explored. Visual fixation can be utilized as a surrogate measure of attention during the management of a trauma patient. We aimed to determine the feasibility of using eye tracking and to characterize eye tracking behaviours of pediatric emergency medicine physicians during management of a simulated pediatric trauma patient. Each participant was equipped with a head-mounted eye tracking device during a standardized simulated pediatric trauma scenario. Each session was video recorded, with visual fixations defined as >0.2 seconds, and characterized by start time, duration, and the area of interest. Data from seven videos were analysed; 35% of eye fixations were directed towards the mannequin, 16% towards the monitor, and 13% towards the bedside doctor. Visual eye tracking in a trauma simulation is feasible. Frequency of fixations tends to be highest towards the patient. Eye tracking within trauma simulation may provide new insights into quality improvement and inform advancements in pediatric trauma.

AB - OBJECTIVE: To evaluate the ability of anthropometric measurements to identify excess android fat and to propose cut-off points for excess central adiposity in children, according to age and sex. DESIGN: A cross-sectional study with children from a municipality of Minas Gerais, Brazil. Receiver-operating characteristic curve analyses were performed to evaluate waist circumference (WC), waist-to height ratio (WHtR) and conicity index (C-index) in estimating excess android fat by dual energy X-ray absorptiometry (DXA). SETTING: Vicosa, Minas Gerais, Brazil. SUBJECTS: Children aged 4-9 years (n 788). RESULTS: Overweight prevalence was 29.1 % and android fat percentage was higher among girls. All central fat measurements were able to discriminate excess android fat in the age groups evaluated, especially WC and WHtR, with cut-off points showing good sensitivity and specificity overall. CONCLUSIONS: Because these methods are easy to obtain and inexpensive, it is possible to use WC, WHtR and C-index in population surveys to evaluate central obesity. The proposed cut-off points showed satisfactory values of sensitivity and specificity and can be used in epidemiological studies. PMID- 30295221 TI - Fruit and vegetable consumption is associated with improved mental and cognitive health in older adults from non-Western developing countries. AB - OBJECTIVES: Consumption of fruits and vegetables has been shown to contribute to mental and cognitive health in older adults from Western industrialized countries. However, it is unclear whether this effect replicates in older adults from non-Western developing countries. Thus, the present study examined the contribution of fruit and vegetable consumption to mental and cognitive health in older persons from China, India, Mexico, Russia, South Africa and Ghana. DESIGN: Representative cross-sectional and cross-national study.Setting/SubjectsWe used data from the WHO Study on Global Ageing and Adult Health (SAGE), sampled in 2007 to 2010. Our final sample size included 28 078 participants. RESULTS: Fruit and vegetable consumption predicted an increased cognitive performance in older adults including improved verbal recall, improved delayed verbal recall, improved digit span test performance and improved verbal fluency; the effect of fruit consumption was much stronger than the effect of vegetable consumption. Regarding mental health, fruit consumption was significantly associated with better subjective quality of life and less depressive symptoms; vegetable consumption, however, did not significantly relate to mental health. CONCLUSIONS: Consumption of fruits is associated with both improved cognitive and mental health in older adults from non-Western developing countries, and consumption of vegetables is associated with improved cognitive health only. Increasing fruit and vegetable consumption might be one easy and cost-effective way to improve the overall health and quality of life of older adults in non-Western developing countries. PMID- 30295222 TI - Tourniquet Training Program Assessed by a New Performance Score. AB - : IntroductionApplication of a tourniquet is the cornerstone in management of combat-related extremity hemorrhages. Continuous and appropriate training is required to use tourniquets correctly.HypothesisThe aim of this study was to analyze the impact of a refresher training session, conducted directly in the theater of military operations, on the performance of tourniquet use. METHODS: During their deployment (October 2015-April 2016) in the Central African Republic, a first simulation session evaluated soldiers from two combats platoons for the application of the SOFFT (Special Operation Forces Tactical Tourniquet; Tactical Medical Solutions; Anderson, South California USA) tourniquet. After randomization, a R (+) group underwent a refresher training session, while a R ( ) group did not. Two months later, a second simulation session was conducted for both groups: R (+) and R (-). A dedicated score (one to seven points), including delay and effectiveness, evaluated the soldiers' performance for tourniquet application. RESULTS: Twenty-six subjects were included in the R (+) group and 24 in the R (-) group. Between the two assessments, the score improved for 61.5% of subjects of the R (+) group and 37.5% subjects of the R (-) group (P=.09). More particularly, the performance score increased from 4.2 (SD=1.4) to 5.5 (SD=0.9; P=.002) in subjects of the R (+) group whose last training for tourniquet application was over six months prior. CONCLUSION: A refresher tourniquet training session, conducted directly in a combat zone, is especially effective for soldiers whose last training session was over six months prior. A dedicated score can assess appropriately the performance of tourniquet training. MartinezT, DuronS, SchaalJV, BaudoinY, BarbierO, DabanJL, BoutonnetM, AussetS, PasquierP.

AB - Following the civil war in Syria, there has been a growing interest in the impact of war, violent conflict, and refuge on the development and mental health of refugee children in general and Syrian refugee children in particular. The objective of this paper is threefold: (a) to critically review the existing literature on the psychological functioning of Syrian refugee children, with a particular focus on those residing in the urban areas or camps in Turkey; (b) to identify the main theoretical and methodological problems of this emerging literature; and (c) to suggest guidelines for how to improve research and practice in this field. The reviewed literature predominantly focuses on psychological trauma, trauma-related symptomatology or other maladaptive functioning in children, and psychosocial interventions conducted toward alleviating these issues. This paper will summarize the research findings in the above-mentioned topics to discern what can be known from the existing literature on Syrian refugee children. PMID- 30295225 TI - Hungarian Managed Care initiatives between 2000 and 2007: regional health outcomes of the Hungarian Care Organizations. AB - BACKGROUND: In Hungary, since 1990, each government has tried to transform and rationalize the structure of health care. One of the reforms was the Care Managing Organization (CMO) programme introduced in 1999. OBJECTIVES: The aim of this paper is to describe the regional, environmental, structural and preliminary health related outcomes of the CMO in Bacs-Kiskun County (Central-Eastern Hungary). METHODS: First, cardiovascular screening programmes were organized for pre-screened and randomly selected populations of a total of 4462 persons. Seven years after completing the programmes, regional mortality data were analysed and compared. Second, nutritional and lifestyle counselling programmes with increased physical activity were organized for 2489 overweight or obese patients from the participating primary care practices. Anthropometric and laboratory data were examined after one and two years. RESULTS: First, for persons with higher cardiovascular risk, appropriate medical treatment was introduced, and after seven years, their mortality rates proved better than the regional and national data. Second, almost all measured anthropometric parameters improved (body mass index, body weight decrease) after the first year and this trend lasted till the end of the second year. CONCLUSIONS: According to the data of the National Health Insurance Fund, the average savings rate for all CMOs for the fiscal years 1999 2007 was 4.94%. The highest rates of savings were realized in chronic and acute inpatient care and medical devices. In the end of 2008, by which time 14 CMOs had already covered 2.1million people, the programme was discontinued by the government, without a comprehensive evaluation of the experience and outcomes. PMID- 30295226 TI - The forgotten foundations: in core mental health services, no one can hear you scream. AB - SummaryThe Five Year Forward View for Mental Health (FYFVMH) was a welcome development in the emerging 'Parity of Esteem' agenda, but focused mainly on a select few specialist services; much more limited attention was given to 'core' general adult and older age mental health services, such as community mental health teams, crisis teams and in-patient units. This relative policy vacuum, when combined with prolonged financial pressures and limited informatics, has left core services vulnerable and struggling to meet growing demands, with little sense of hope, in contrast to some of the newer, 'shiny' specialist services growing around them. Policy makers need to recognise the growing crisis and take action, ensuring that any sequel to the FYFVMH redresses this imbalance by clearly prioritising core services as the vital foundations of the larger whole system. The potential benefits are huge and wide-ranging, but the harms of a second missed opportunity are perhaps even greater.Declaration of interestA.M. works in a National Health Service general adult community mental health team and is an elected member of the Royal College of Psychiatrists General Adult Faculty Executive Committee.

PMID- 30295227 TI - Beverage consumption patterns and energy contribution from beverages per meal type: results from a national dietary survey in Sweden. AB - OBJECTIVE: Many studies of food intake have been performed and published in Sweden, but to our knowledge no studies have extensively explored the beverage consumption of the Swedish adult population. The present study aimed to describe the beverage consumption and the contribution of beverage energy (including alcohol energy) to total energy intake according to gender, region of living, meal type and day for a Swedish adult population. DESIGN: National dietary survey Riksmaten (2010-2011), collected by the Swedish National Food Agency. SETTING: Sweden. SUBJECTS: A total of 1682 participants (57 % women) reported dietary intake data during four consecutive days, specified by portion size, meal, time point, day of the week and venue. Meals were categorized as breakfast, lunch, dinner and 'other'.ResultThe beverage reported to be consumed the most was water (ml/d), followed by coffee. Men had a higher consumption of juice, soft drinks, beer, spirits and low-alcohol beer, while the consumption of tea and water was higher for women. For both genders, milk contributed the most to beverage energy intake. Energy percentage from beverages was higher at lunch and dinner during weekends for both genders. Participants from the biggest cities in Sweden had a higher consumption of wine for both genders and tea for men than participants from other regions. CONCLUSIONS: A considerable part of total energy intake was contributed by beverages, especially for men. Beverages can contribute to a more enjoyable diet, but at the same time provide energy, sugar and alcohol in amounts that do not promote optimal health. PMID- 30295229 TI - Advancing population health science to public health policy. PMID- 30295231 TI - Determinants of low birth weight in the context of maternal nutrition education in urban informal settlements, Kenya. AB - Inadequate knowledge in maternal nutrition is one of the determinants of low birth weight. However, little evidence is available on whether maternal nutrition counselling alone can influence birth weight among women from low socioeconomic households. This study assessed the effect of prenatal maternal nutritional counselling on birth weight and examined the related risk factors. A cluster randomized controlled trial was conducted to assess the effectiveness of home based maternal nutritional counselling on nutritional outcomes, morbidity, breastfeeding, and infant feeding practices by the African Population and Health Research Center in two urban informal settlements of Nairobi. The intervention group received monthly antenatal and nutritional counselling from trained community health volunteers; meanwhile, the control group received routine antenatal care. A total of 1001 participants were included for analysis. Logistic regression was applied to determine associations between low birth weight and maternal characteristics. A higher prevalence of low birth weight was observed in the control group (6.7%) than in the intervention group (2.5%; P<0.001). Logistic regression identified significant associations between birth weight and intervention group (adjusted odds ratio (AOR)=0.26; 95% confidence interval (CI), 0.10-0.64); maternal height <154.5 cm (AOR=3.33; 95% CI, 1.01-10.96); last antenatal care visits at 1st or 2nd trimesters (AOR=9.48; 95% CI, 3.72-24.15); pre-term delivery (AOR=3.93; 95% CI, 1.93-7.98); maternal mid-upper arm circumference <23 cm (AOR=2.57; 95% CI, 1.15-5.78); and cesarean delivery (AOR=2.27; 95% CI, 1.04-4.94). Nutrition counselling during pregnancy reduced low birth weight and preterm births, which was determined by women of short stature, early stoppage of antenatal visit, and cesarean delivery. PMID- 30295232 TI - Examining the validity of the ADHD concept in adults and older adults. AB - OBJECTIVE: It is crucial to clarify the structure of attention deficit/hyperactivity disorder (ADHD) symptomatology in all age groups to determine how to best conceptualize this disorder across the lifespan. We tested the ADHD factor structure across adulthood and investigated independent associations with executive functions. METHOD: Data from 645 adults aged 18-59 and 233 adults aged 60-85 were drawn from the Nathan Kline Institute Rockland Sample. Participants completed the Conners Adult ADHD Rating Scale and tests of executive functioning. Invariance of the ADHD factor structure was investigated using confirmatory factor analyses. Associations with cognition were explored using multiple linear regression. RESULTS: Results confirmed a bifactor model with 3 specific factors (inattention, hyperactivity, and impulsivity). Factor loadings and item intercepts were invariant across ages. Levels of hyperactivity and impulsivity were lower in older adults. Inattentive symptoms in young adults were positively related to cognitive flexibility. In older adults, ADHD symptoms predicted poorer working memory. CONCLUSION: ADHD symptoms manifest similarly across adulthood. The lack of robust associations between ADHD symptomatology and executive functions raises concerns about the usefulness of neuropsychological measures in diagnosing adult ADHD. These results support the validity of the ADHD concept in older adults but suggest a need for age-appropriate normative criteria. PMID- 30295233 TI - General practitioners cannot rely on reported weight and height of children. AB - AIM: The aim of this study is to investigate the differences between reported and measured weight and height for underweight, normal-weight, and overweight children, particularly in a general practitioner setting. BACKGROUND: Screening, signaling, and treatment of childhood obesity by the general practitioner depends on accurate weight and height measurements. METHODS: Data on reported and measured weight and height from a cohort including 715 normal-weight and overweight children aged 2-17 were used. Means of reported and measured weight and height were compared using the paired T-test. FINDINGS: Of the 715 included children, 17.5% were defined as being underweight, 63.2% normal-weight, and 19.3% overweight according to direct measured height and weight. In the age group 2-8 years, parents of underweight children reported a significantly higher weight than measured weight [mean differences (MD) 0.32 kg (0.02, 0.62)], whereas parents of overweight young children reported a significantly lower weight [MD 1.08 kg (-1.77, -0.39)]. In the age group 9-17 years, normal-weight [MD -0.51 kg (-0.79, -0.23)] and overweight children [MD -1.28 kg (-2.08, -0.47)] reported a significantly lower weight than measured weight. CONCLUSIONS: General practitioners cannot rely on reported weight and height measures from parents and children. In case of suspected under- or overweight in children, it should be advised to measure weight and height in general practice. PMID- 30295234 TI - Varzaghan Earthquake Affected Mothers' and Their Newborns' Health More Severely, in Socioeconomically Vulnerable Area. AB - OBJECTIVE: We aimed to compare the pregnancy status of the pregnant women and birth status of their newborns, socioeconomic status, and access to health services, between high- and low-damage areas in Heris, affected by the Varzaghan Earthquake, 2012. METHODS: The study was conducted on pregnant women at any trimester of pregnancy (with complete medical profiles in local health centers) in August 2012 (time of the earthquake) who lived in Heris and delivered up to March 2013. Data were obtained on pregnancy- and infant-related variables, housing, socioeconomic status, and access to health services, including food supplies, before and after the earthquake. RESULTS: Family income and mothers' education were lower in highly damaged areas. Among these women, underweight at first trimester of pregnancy was higher, and weight gain during the last trimester was lower, compared with low-damage regions. Preterm delivery was higher in low-damage areas. Birth indices of the infants were not significantly different between the 2 areas; however, in highly damaged areas, moderate malnutrition was more prevalent among children under 1 year (weight-for-age) and under 2 years (height-for-age). CONCLUSIONS: Socioeconomic status of mothers was lower in highly damaged areas and might have played a role in their own and newborns' health status.

AB - OBJECTIVE: To construct a lentiviral vector carrying human CUEDC1 gene, to establish leukemic cell line MOLT-4 stably expressing recombinant plasmid, to analyze the expression of CUEDC1 in MOLT-4 cells and to investigate its effect on the proliferation of MOLT-4 cells. METHODS: The CUEDC1 gene was amplified by RT PCR, and then was subcloned into the lentiviral vector pCDH to generate a lentiviral vector pCDH-CUEDC1. Recombinant lentivirus was generated by co transfection of 3 plasmids, and transfected into MOLT-4 cells. The Real-time PCR and Western blot were respectively applied to detect the expression of CUEDC1 mRNA and protein, the CCK-8 and colony formation assay were used to evaluate the effect of CUEDC1 on proliferation of MOLT-4 cells. RESULTS: The recombinant lentiviral vector pCDH-CUEDC1 had been constructed successfully. After infection of MOLT-4 cells with the lentivirus, the recombinant plasmid could stably up regulate the expression of CUEDC1 and protein. The CCK-8 detection and colony formation assay showed that exogenous CUEDC1 could significantly promote cell growth and the colony formation of MOLT-4 cells. CONCLUSION: The recombinant lentiviral vector carrying human CUEDC1 has been successfully constructed, exogenous CUEDC1 can significantly promote cell growth and the colony formation of MOLT-4 cells. PMID- 30295236 TI - [Analysis of Heterogeneous Biological Characteristics and Prognosis-Related Factors in AL Patients with Mistranslation-Expressed Lymphoid and Myeloid-Related Antigen]. AB - OBJECTIVE: To analyze the heterogeneous biological characteristics of acute leukemia (AL) patients with mistranslation expressed lymphoid and myeloid-related antigens, and it's prognosis-related factors. METHODS: Two hundred and fourteen AL patiens with mistranslation expressed lymphoid and myeloid-related antigens were grouped according to immunophenotypes, and the heterogeneous biologic charecteristics and prognosis related factors were analyzed, moreover the survival curves were drawn to analyze the survival of patiens. RESULTS: The immunophenotype in 214 cases was mainly cross-expression of myeloid and B lineage antigen (118 cases), followed by cross-expression of myeloid antigen and T lineage (88 cases), while the cross-expression of myeloid, T and B lineages, was less (only 8 cases). In ALL patiens with cross-expression of myeloid antigen, the CD33 was main type; while in AML patients with cross-expression of lymphoid antigen, CD7 was main type of lineage antigen, CD19 was main type of B lineage antigen. Among 214 AL patients, the cross-expression of CD55 and myeloid antigen was found in 30 cases, the cross-expression of CD7, CD19 and CD74 was observed in 6 cases, the cross-expressions of CD7, CD34 and CD56 was detected in 4 cases. Among AML patients with lymphoid antigen expression, the recurrent chromosmal abnormalities were found in 16 cases; among ALL patients with myeloid antigen expression, the recurrent chromosomal abnormalities were observed in 10 cases. The mistranslation antigen expression existed in 26 patients with recurrent chromosomal abnormalities, the mistranslated CD33 and CD13 in ALL patients with myeloid antigen expression was common, while the mistranslated CD2, CD56 and CD19 in AML patients with lymphoid antigen expression was common. As compared with patients without lymphoid antigen expression, the survival rate decreased significantly in patients with mistranslated CD7(+) and CD34(+) (both P<0.05). The logistic regression analysis showed that CD7, CD34 were main influencing factors for prognosis of AL patients (both P<0.05). CONCLUSION: The AL with mistranslation expressed lymphoid and myeloid antigens is a special kind of leukemia which possesses the heterogencous biological characteristcs and unique prognostic features, thus the immunophemotype of AL patients should be detected by flow cytometry. The existance of mistranlation-expressed differatiation antigens such as CD7 and CD34 is mainly influencing factors for the prognosis of AL patiens. PMID- 30295237 TI - [Primary Prophylatic Effect of Voriconazole Against Invasive Infection of Pulmonary Aspergillosis during Remission-Induction Chemotherapy for Acute Myeloid Leukemia]. AB - OBJECTIVE: To evaluate the efficacy of primary prophylaxis of voriconazole against invasive infection of pulmonary aspergillosis (IPA) during remission induction chemotherapy (RIC) of patients with acute myeloid leukemia (AML). METHODS: Clinical data of 102 de novo AML patients who received primary anti-IPA prophylaxis during the first induction chemotherapy were analyzed retrospectively. All the cases were divided into voriconazole-treated group and posaconazole-treated group according to the prophylactic agent. The incidences of IPA and systemic antifungal treatment during induction chemotherapy were analyzed for both groups. RESULTS: Among 102 enrolled cases, 42 cases received voriconazole and other 60 received posaconazole as primary prophylaxis. IPA occurred in 3 cases of voriconazole group (1 probable, 2 possible); IPA occurred in 4 cases of posaconazose group, and all were possible cases. The incidence of IPA during remission-induction chemotherapy in variconazole group equaled to posaconazose group (7.1% vs. 6.7%) (P=0.925). Beside IPA cases, 2 cases in voriconazole group and 4 cases in posaconazole group received intravenous anti aspergillosis drugs preemptive treatment, and no significant difference of prophylactic success rate was observed between two groups (88.1% vs. 86.7%) (P=0.831). Visual disturbance was the most common adverse event occurred in voriconazole group, but no significant differences of incidences of other adverse effects were observed when compared with posaconazole group. CONCLUSION: According to similar prophylactic effect with posaconazole, voriconazole appears to be a good alternative for primary prophylaxis of IPA during remission induction chemotherapy in AML patients. PMID- 30295238 TI - [Effect of Additional Chromosomal Abnormalities on the Outcome of CML-CP Patients Receiving TKI Therapy]. AB - OBJECTIVES: To explore the effect of additional chromosomal abnormalities on the prognosis and outcome of CML-CP patients receiving imatinib therapy. METHODS: The clinical and genetic data of 589 CML-CP patients receiving imatinib treatment between May 2009 and October 2014 in the 1st Affiliated Hospital of Soochow University were analyzed, the 589 patients were divided into 5 groups according to the karyotypes at the initial diagnosis. The OS(overall survival), PFS (progression-free survival), EFS (event-free survival), Cumulative MMR (major molecular remission) and Cumulative CCyR (complete cytogenetic remission) were calculated by using the Kaplan-Meier method and compared by using the log-rank text by Graphpad 6.0. The chi2 test was used to compare the frequency of optimal molecular response at 3, 6, 12 months among the 5 groups. RESULTS: There was significant difference about the frequency of optimal molecular response at 3 and 6 months between CML-CP patients with additional chromosomal abnormalities and those with classic t(9;22) [50%(12/24) vs. 73.94%(261 /353), P<0.05; 50%(10 /20) vs. 72.05%(232 /322) (P<0.05)], and the same significant difference was found at 6 months between the group with variant translocations and that with classic t(9;22) [53.3% (16 /30) vs. 72.05%(232 /322) (P<0.05)]. The P values of cumulative CCyR (P<0.05) and EFS (P<0.01) for 4 years were statistically significant between CML-CP patients with additional chromosomal abnormalities and the other 4 groups. Compared one to another, there was the significant difference in cumulative CCyR and EFS for 4 years between CML-CP patients with additional chromosomal.abnormalities and those with classic t(9;22) (47.25% vs. 84.01%)(P<0.05); (75.03% vs. 90.01%)(P<0.01). CONCLUSION: The additional chromosomal abnormalities influence the outcome of CML-CP patients receiving imatinib treatment, which make poor prognosis. PMID- 30295239 TI - [Relationship between BCR-ABLIS and Prognosis and Affecting Factors for Prognosis in CML Patients Treated with TKI for 12 Months]. AB - OBJECTIVE: To evaluate the long-term prognosis of CML patients whose BCR-ABL transcript level was warning and best response at 12 months of treatment with tyrosine kinase inhititor (TKI), and to investigate the factors affecting therapeutic efficacy and prognosis. METHODS: The clinical data of patients with newly diagnosed CML were analyzed retrospectively. According to BCR-ABL transcript level, the 80 patients were divided into group A and group B, the patients with BCR-ABLIS >0.1% and <= 1% (warning response) were entolled in group A, and the patients with BCR-ABLIS <= 0.1% (best response) were enrolled in group B as control. The ratio of patients with main molecular response (MMR) and deep molecular response (DMR), as well as aquistation rate and cummulative rate of MR4 (DMR) at specified fine points in 2 groups were compared, the independent risk factors affecting the therapeutic efficacy and prognosis were analyzed. RESULTS: The MMR and MR4 of the B group at 15, 18 and 24 months after TKI treatment were significantly higher than those of the A group, and the patients in the B group reached MR4 faster. In the 3 months, 6 months and 12 months after the demarcation point (TKI 12 months), the A group was much less easy to obtain MR4 (P<0.05) than the B group. Through survival analysis, there were more patients in the B group than the A group at different time points to reach MR4, and the difference was statistically significant (P<0.01). The single factor analysis showed that the splenomegaly (below rib edge)> 10cm (P<0.01) and lactate dehydrogenase > 400 U/L (P<0.05) were the long-term warning factors for patients. Multivariate analysis showed that the size of the spleen was an independent factor (P<0.01) to affect the prognosis of the patients who had been warned for 12 months. CONCLUSION: Patients at 12 months warning effect are slower and less easier to get DMR, which has a poor long-term prognosis. The size of the spleen in the patient at warning for 12 months of treatment effect can predict the relatively poor long-term prognosis. For a patient with a 12 months response to the warning, an early replacement therapy is available on the basis of combining other factors..

AB - OBJECTIVE: To investigate the effects of epigallocatechin-3-gallate (EGCG) on proliferation and cell cycle of acute promyelocytic leukemia NB4 cell line and to clarify the molecular mechanism. METHODS: NB4 cells were treated with 0,50,75,100 and 125umol/L of EGCG for 24, 48, 72 and 96 h, respectively. The proliferation level of NB4 cells was measured by CCK-8 assay. The cell cycle progression of NB4 cells was assayed by flow cytometry. The mRNA expression levels of DNMT1, DNMT3a and DAPK1 were detected by RT-PCR. The methylation status of gene was tested by methylation specific PCR, and the expression level of DAPK1 protein was detected by Western blot. RESULTS: The proliferation and cell cycle progression of NB4 cells treated with EGCG were inhibited and showed the characteristic of time dependent and dose-dependent manner. The expression level of DAPK1 and DNMT3a decreased in NB4 cells treated with EGCG. The expression level of DAPK increased in NB4 cells treated with EGCG, while the methylation of DAPK1 gene decreased. CONCLUSION: EGCG inhibits the proliferation and cell cycle progression of NB4 cells by inhibiting the expression of DNMT1 and DNMT3a and down-regulating the methylation status of DAPK1 gene.

AB - OBJECTIVE: To investigate the mutation rate and mutation characteristics of FBXW7 and NOTCH1 in adult T-ALL, and to study the effect of these 2 mutations on the clinical features and prognosis of patients with adult T-ALL. METHODS: The mutations of FBXW7 and NOTCH1 in 106 adult T-ALL patients were determined by gene sequencing of FBXW7 and NOTCH1 genes. and the clinical characteristics and prognosis were compared. RESULTS: Among the 106 cases of adult T-ALL, there were 21 cases (19.8%) of FBXW7 mutation, 66 cases (62.3%) of NOTCH1 mutation and 18 cases (17.0%) of FBXW7 / NOTCH1 double mutations. The 2-year cumulative overall survival rate and event-free survival rate of the patiants in FBXW7 / NOTCH1 double mutant group were lower than those without mutations (27.8% vs 70.3%)(P<0.01) and (16.7% vs 48.6%) ( P<0.01) respectivly, but the FBXW7 or NOTCH1 mutations had a little effect on the prognosis. The recurrence rate at mutant group was higher than that of the non - mutant group (77.8% vs 43.2%) (P<0.05). CONCLUSION: FBXW7 or NOTCH1 mutations can not be as the prognostic factors, but the FBXW7 / NOTCH1 double mutations may indicate poor prognosis.

AB - OBJECTIVE: To determine whether immune differentiation antigen is related with clinical features and minimal residual disease (MRD) in childhood B-cell precursor acute lymphoblastic leukemia (B-ALL), who were treated with CCCG-ALL 2015 protocol. METHODS: A retrospective analysis was conducted in 132 B-ALL children, Multiparametric flow cytometry was used to analyze the immunophenotypes. The children were divided into 2 groups by MRD>0.1% on d 19 and / or d 46 after chemotherapy. The Wilcoxon rank-sum test and chi2 test were used for the comparison between groups, and P<0.05 was considered statistically significant. RESULTS: CD19 (100%), CD22 (99.3%) and cCD79a (97.9%) were specific markers for patients with B-ALL, the CD13 and CD33 were mainly cross myeloid antigen. The significant differences were found between CD45- and CD45+ in WBC counts when being firstly diagnosed (Z=6.845, P<0.01), risk stratification (chi2=8.260, P<0.05) and prednisone poor responder (chi2=18.420, P<0.01). Significant differences were found between CD10- and CD10+ in age (Z=6.253, P<0.05), risk stratification (chi2=6.699, P<0.05) and MRD (chi2=4.951, P<0.05). CONCLUSION: In CCCG-ALL-2015 protocol, the CD10 relates with the early MRD, suggesting a better prognosis, and reducing the adverse effects of CD20 and cross myeloid antigen on prognosis. PMID- 30295243 TI - [Changes of T Cell Subsets and Their Relationship with Clinical Features and Prognosis in Patients with Acute Leukemia]. AB - OBJECTIVE: To analyze the relationship between T cell subsets and clinical data. METHODS: mononuclear cells were collected from 103 patients with acute leukemia (AL) and 28 healthy volunteers, and percentage changes of CD3+CD4+, CD3+CD8+ and CD4+ CD25+ Foxp3+ cell subsets were assayed by flow cytometory. Relationship between the T subsets and clinical features of the patients was analyzed. RESULTS: Ratio of CD3+ T cells decreased more significantly in patients with >50% blast cells than that in patients with <50% blast cells, while the ratio of Treg between the 2 groups was not significantly different. Treg increased more statistically significantly in the patients with CD34+ leukemia cell than that with CD34- leukemia cells. In constrast to the relationship between prognosis and immune cells in the patients from 3 groups (low, intermediate and high-risk group) it was found that Treg cells increased more significantly in high-risk group than that in low-risk group. By continuously monitoring immune cells in 18 patients, it was found that Treg cells gradually increased during the first 3 courses of chemotherapy, then began to decreased in the 4th course, finally approached gradually to the normal value in the 6th course, and this change correlated with the clinical remission after chemotherapy. Treg cell number in the patients with AL was significantly higher than that in healthy controls, and Treg cell number during the onset and recurrence was significantly higher than that in the period of complete remission (continuous remission for over 6 months). Compared with the changes of immune cell number between different types of disease, it was found that Treg cells were increased more significantly in acute myeloid leukemia (AML) than that in acute lymphoblastic leukemia (ALL). Proportion of Treg cells, Treg/CD4 decreased more significantly after the 1st course of chemotherapy in the group with complete remission (CR) than that in the group without CR. The complete remission rate and recurrence rate were 68.9% and 20% respectively in the group with >10% Treg cells, while the complete remission rate and recurrence rate were 85.7% and 7.69% respectively in the group with.<10% Treg cells. In comparison of the 6 recurrent patients with 32 patients with sustained CR, it was found that the ratio of Treg cells and Treg/CD4 was increased more significantly in the patients with relapse than that with CR and in control group. CONCLUSION: Dynamic change of Treg cells in the peripheral blood was closely related with clinical feature, recurrence and prognosis in the patients with acute leukemia.

AB - OBJECTIVE: To expolore the effect of programmed death receptor ligand 1 (PD-L1) expression level on killing effect of different cell lines of acute myeloid leukemia (AML) and its possible mechanism. METHODS: Peripheral blood from healthy individuals was collected routinely; NK cells were isolated using immunomagnetic beads; PD-L1 expression level was detected by flow cytometry; the killing effect of NK cells on acute myelogenous leukemia cell lines was evaluated with LDH release method and monoclonal antibody blocking experiment; the expression levels of IFN-gamma and IL-2 in the supernatants from the co-cultured effector/targer cells were measured by ELISA. RESULTS: The ratio of CD3-CD56+NK cells increased from (12.44+/-3.48)% to (71.29+/-5.65)%. The flow cytometry showed that KG-1a cells lowly expressed PD-L1 (8.35+/-4.12)%, but the THP cells a highly expressed PD-L1 (76.42+/-26.54)%. Meanwhile, the NK cells displayed a more efficient killing effect on KG-1a cells than that of THP1 cells (P<0.05). Moreover, PD-L1 monoclonal antibody could reinforce NK cell killing effect and, promote the secretion of IFN-gamma and IL-2 in 5 acute myelogenous leukemia cell lines to varying degree. CONCLUSION: The killing effect of NK cells on acute myelogenous leukemia cell line is inversely proportional to PD-L1 expression; blocking PD1/PD L1 binding can significantly enhance the killing efficiency of effector-target cells, which way be related with promoting the release of IFN-gamma and IL-2. PMID- 30295245 TI - [Expression of EVI1 in Bone Marrow of Patients with AML and ALL and Its Correlation with Leukemia Subtyping, Clinical Features and Prognosis of Patients]. AB - OBJECTIVE: To explore the expression of EVI1 gene in AML and the ALL patients' bone marrow cells, and its correlation with the leukemic typing, clinical characteristics and prognosis. METHODS: Three hundred and thirty-three cases of leukemia in our hospital from 2012 to 2016 were enrolled in this study. Among them there were 263 cases of AML, 70 cases of ALL, and 13 volunteers were selected as normal controls. The bone marrow samples of the patients and volunteers were aspirated. Firstly, the blood mononuclear cells(PBMNC) were separated from the samples through the Ficoll-Hypaque density gradient centrifugation. Secondly, the total DNA was extracted, and the expression of EVI1 mRNA were assayed by real-ime quantitative PCR, which help to find out the EVI1 mRNA expression difference between AML and ALL. Finally, the correlation of EVI1 expression with the acute leukemia typing, clinical characteristics and prognosis were analyzed by a series of statistical method. RESULTS: Based on the expression levels of the EVI1 mRNA determined by real-time quantitative PCR, the expression levels in AML and ALL were both higher, but without significant difference. The rates of both EVI1 mRNA overexpression and low expression of the EVI1 mRNA in AML patients were higher than those in AML group, however, the rate of normal expression in ALL group was statistically significantly lower than that in the AML. The level of Plt in patients with AML-M1 and T-ALL positively correlated with the level of EVI1 expression(r=0.393,P<0.05;rho=0.442,P<0.05)while the level of blasts(%) in patients with AML-M3 negatively correlated with the level of EVI1 expression. The expression of EVI1 correlated with the age of patients(chi2 =6.684,P<0.05). The prognosis of AML patients with high expression of EVI1 mRNA was poor(Log-Rank test,P<0.05)and AML-M3 patients with high expression of EVI1 had a significantly poorer prognosis than that of patients without high expression(Log-Rank test,P<0.01). CONCLUSION: In expression level of EVI1 no difference has been found in AML and ALL, but the distribution of EVI1 expression shows obvious difference and the difference correlats with the age of patients, at the same time, the some clinical features and subtype of acute leukemia correlate with the expression level of EVI1.

PMID- 30295248 TI - [Value of 18F-FDG PET/CT Scan Quantization Parameters for Prognostic Evaluation of Patients with Diffuse Large B-cells Lymphoma]. AB - OBJECTIVE: To investigate the prognostic value of 18F-FDG PET/CT scan quantization parameters, max standardized uptake value (SUVmax), metabolic tumor volume (MTV), total lesion glycolysis (TLG) and other clinical factors for prognostic evaluation of paticnts with diffuse large B-cell lymphoma (DLBCL). METHODS: PET/CT scan and clinical data of a total of 65 newly diagnosed DLBCL patients who received Rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) chemotherapy as first-line treatment were analyzed. All patients received a PET/CT scan at diagnosis and an interim PET/CT after 2-4 circles of chemotherapies. The related parameters of SUVmax, MTV and TLG were acquired by analyzing and calculating the scan results. The receiver operating characteristic (ROC) curve was used to determine the optimal cut-off of parameters. Pearson chi-square test, Kaplan-Meier method and COX proportional hazard model were performed to analyze the prognostic value of PET/CT related parameters and clinical factors in progression-free survival (PFS). RESULTS: Age, B symptom, Ann Arbor stage and extra-nodal involvement in major organs significantly related with PFS (P<0.05), but the SUVmax didn't relalt with the prognosis. The cut-off values of MTV0, MTV1, TLG0 and TLG1 for disease recurrence or progression were 172.20cm 3, 4.32cm 3, 1043.33g and 14.07g. The lower MTV and TLG groups showed longer PFS significantly. In the multivariate Cox regression model, B symptoms, MTV1 and TLG1 were the independent prognostic risk factors. CONCLUSION: MTV and TLG at baseline and in the interim and NCCN-IPI correlate with disease prognosis. SUVmax related parameters hare no significant relationship with prognosis. Besides MTV and TLG during treatment are the independent prognostic risk factors suggesting more predictive value than NCCN IPI.

AB - OBJECTIVE: To analyse the clinical characteristics and therapeutic efticacy of patients with mantle cell lymphoma(MCL). METHODS: The clinical data including cliniced parameters and laboratorial test results of 54 patients with MCL were collected and restrospectively analyzed to clarity the clinical characteristics of MCL and to evaluate the survival and factors affecting prgnosis of patients. RESULTS: The incidence of MCL accounted for 4.0% of NHL in our center. The median age of MCL patients was 63 years old, the male and female ratio was 1.4?1. The MCL patients inIII-IV stage accounted for 96.3%; the extranodal organ involvement existed in 98.1% patients, the most common extranodal involvement sites were bone marrow(72.2%), spleen(51.9%), gastrointestinal tract(25.9%). The overall response rate(ORR) was 66.7%, among which the complete remisson (CR) rate was 37.1%, 3 year and 5 year-progression free survival rate was 52.7% and 34.7% respectively, 3 year and 5 year overall survival rate was 60.4% and 49.6% respectively. The therapeutic efficacy in chemotherapy combined with cytarabine group was suprior to that in chemotherapy group without cyteratine, the chemotherapy comtined with auto-HSCT could further improve the prognosis of patients. The unvariatc analysis showed that the KI67 level, B sgmptom, liver function, LDH and C-RP levels, initial therapeutic efficacy, high dose cytarabine regimen, auto-HSCT and relapse refractroy status were prognosis-related factors; the multi-variate analysis showed that the initial therapeutic efficacy and relapse rcfractory stasus were independent prognostic risk factors. Analysis showed that the surival of patients stratified according to MIPI and MIPI-c indexes was significantly different from that stratified by IPI index. CONCLUSION: The MCL patients commonly complicated by extranodal involvement and have poor prognoss. Using the chenotherapy regimen combined with high doge of cytarabine as induction therapy and auto-HSCT as consotidatory therapy shows the significont efficacy for survival of young patients with MCL. The MIPI and MIPIc indexe are more much suitable for prognosis evaluation of MCL patients.The initial therapeuntic efficacy and relapse refractrong status are the independant prognosis-related factors.

AB - OBJECTIVE: To evaluate the clinicopathological characteristics, treatment and prognosis of the patients with plasmablastic lymphoma(PBL). METHODS: The clinical and pathological data of 21 patients with PBL diagnosed and treated in our center between January 2009 and September 2017 were retrospectively analyzed. The clinical and pathological features, treatment and therapentic outcome were summarized and the high risk factors affecting the prognosis of patients were investigated. RESULTS: The 21 PBL patients included 12 males and 9 females, and their median age was 52 years old. The human immunodeficiency virus (HIV) was negative in all patients. The primary involved sites of 16 patients were extranodal, and the patients staged in III-IV accounted for 81%; 18 patients receved first-line chemotherapy with standard CHOP(E) (cyclophosphamide +epirubicin +vincristine +prednisone+/-etoposide). After treatment, only 1 patient achieved complete response (CR), and 8 patients achieved partial response (PR). The median overall survival time was 6.3 months. Multivariate analysis showed the America Eastern Cooperative Oncology Group (ECOG) physical score and bone marrow infiltration were significant prognostic factors (P<0.01). CONCLUSION: Plasmablastic lymphoma frequently occurrs in the middle-old aged persons with all HIV negative. Primary extranodal lesions are frequent. Most patients were in advanced stage with poor treatment response. ECOG score>=2 and bone marrow infiltration are independent prognostic factors related with worse prognosis.

AB - OBJECTIVE: To analyze the effect of autologous hematopoietic stem cell transplantation in the treatment of patients with recurrent refractory B cell non Hodgkin's lymphoma (NHL) and the related factors affecting the prognosis. METHODS: The clinical data of 47 cases of recurrent refractory B cell NHL treated in our hospital were retrospectively analyzed. Survival curves were drawn by Kaplan-Meier, and survival analyses were performed. Univariate and multivariate analyses were used to analyze the prognostic factors. RESULTS: The complete remission rate was 51.06% before autologous hematopoietic stem cell transplantation, but it increased to 65.96% after transplantation. The median survival time was 21 months, the 3 years progression-free survival rate was 40.43%, and the 3 years overall survival rate was 48.94%. The results of unvariate analysis showed that no using the rituximab in the first treatment and incomplete remission shown by PET/CT before transplantation all were the risk factors (P<0.05) affecting the prognosis. By multifactor analysis, it was found that the incomplete remission shown by PET/CT before transplantation was a risk factor for the prognosis(P<0.05). CONCLUSION: The application of autologous hematopoietic stem cell transplantation for patients with relapsed and refractory B cell NHL can improve the clinical efficacy, and the incomplete remission shown by PET/CT before transplantation is more adverse to the patients' prognosis.

AB - OBJECTIVE: To detect the molecular cytogenetic abnormalities of multiple myeloma (MM) by using microrray-based comparative genomic hybridization (array-CGH) technology and to investigate its value of application in MM. METHODS: The whole genoine copy number variants (CNV) of bone marrow samples acquired from 20 cases of newly diagnosed MM patients were detected by genome-wide hybridization and scanning by CytoScan 750K Array (Affymetrix). At the same time, the chromosome abnormalities of bone marrow cells were detected by karyotype analysis and FISH using 9 specific probes: D13S319, RB1, p53, 1q21, IgH, IgH/CCND1, IgH/FGFR3, IgH/MAF, IgH/MAFB. RESULTS: Among the 20 MM patients, the incidence of chromosome abnormalities detected by karyotype analysis, FISH and array-CGH were 15%, 65% and 90%, respectively. The types of CNV detected by array-CGH included the gain (106), loss (156) or UPD (23). There were many different CNVs in every chromosomes except chromosome 5, 9, 18, 21 and Y. Comparison of chromosome abnormalities detected by FISH and array-CGH showed that, the positive ratio of del (13q) was 35% and 40% respectively; the positive ratio of amp (1q) was 40% and 50% respectively; the positive ratio of del (17p) was both 15%. FISH detection showed 8 cases with IgH rearrangement, meansahile the array-CGH detection showed that 4 cases had amp (11q13) (CCND1 gene), 3 cases had amp (16q23) (MAF gene), 1 case had amp (4p16) (FGFR3 gene) and 2 cases had amp (20q12) (MAFB gene). Besides, many other new chromosome abnormalities were found. CONCLUSION: More than half of MM patients have cytogenetic changes, and most of them are complex chromosomal abnormalities. By using array-CGH, more chromosome abnormalities can be detected and more cytogenetic information can be provided for clinician. PMID- 30295257 TI - [Clinical Analysis on the Therapeutic Efficacy of Autologous Hematopoietic Stem Cell Transplantation in 56 Multiple Myeloma Patients]. AB - OBJECTIVE: To evaluate the therapeutic efficacy and prognosis of autologous stem Hematopoietic cell transplantation (auto-HSCT) in multiple myeloma (MM) patients. METHODS: A retrospective study was conducted for 56 patients diagnosed with MM and then received auto-HSCT in our hospital from December 2008 to September 2016. RESULTS: All the patients successfully underwent hematopoietic reconstruction without transplantation-related mortality (TRM). The complete response (CR) rate of all the patients after induction chemotherapy was 23.2% (13/56), while the CR rate of these patients with auto-HSCT increased to 78.6% (44/56) (P<0.01). The CR plus VGPR (very good partial response) rates of these 56 patients after induction chemotherapy and auto-HSCT were 53.6%(30/56)and 94.6%(53/56) respectively (P<0.01). The median progression-free survival (PFS) time and median overall survival (OS) time were 37 and 71 months, respectively. The median PFS time in the patients with induction therapy containing bortezomib was 37 months, however, the median OS time did not reach to 71 months; the median PFS (P<0.01) and the median OS (P<0.01) in the patients with the induction chemotherapy without bortezomib was 27 and 51 months, respectively. Univariate analysis demonstrated that the patients maintained CR or VGPR after auto-HSCT or with less than 6 cycles of induction chemotherapy significantly correlated with PFS (P<0.01). CONCLUSION: auto-HSCT can further increase the CR rate, prolong PFS and OS time. Sequential auto-HSCT after bortezomib-based therapy is the first line therapy for the transplant-eligible MM patients. Maintenance treatment is beneficial to the sustained CR+VGPR patients after auto-HSCT. PMID- 30295258 TI - [Chromosomal Abnormalities Associated with Clinical Outcome in Patients with Newly Diagnosed Multiple Myeloma]. AB - OBJECTIVE: To investigate the prognostic value of karyotypic abnormalities in evaluation of prognosis of patients with multiple myeloma. METHODS: The clinical and laboratory data of patients with newly diagnosed multiple myeloma (NDMM) were retrospectively analyzed in our hospital from May 2010 to May 2016. Patients who carried t(4; 14), t(14; 16) or 17P- (at least one of them) were defined as the patients with high-risk karyotype, whereas patients characterized by the absence of the above-mentioned abnormalities were defined as patients with standard-risk karyotype. PFS (progression-free survival, PFS) and OS (over all survival, OS) time was compared between the 2 groups. RESULTS: There were 110 cases in the high risk group, and 302 cases in the standard-risk group. The clinical characteristics, such as age, sex, ISS stage and treatment regimen etc were not statistically different between 2 groups. The median OS time of patients in the high-risk and standard-risk groups were 42 months (CI 95%: 34.375-49.625 months) and 53 months (CI 95%: 46.310-59.690 months) (P<0.05). The median PFS time of patients in the high-risk group and standard-risk groups was 21 months (CI95%: 17.198-24.802 months) and 27 months (CI95%: 23.406-30.594 months) (P<0.05). CONCLUSION: Among patients with newly diagnosed MM, the PFS and OS time in the patients with high-risk karyotype is shorter than that in patients with standard risk karyotyp.

AB - OBJECTIVE: To analyze the clinical efficacy and possible influencing factors of autologous hematopoietic Stem cell transplantation (auto-HSCT) in the treatment of patients with multiple myeloma (MM). METHODS: Clinical data of 40 MM patients received auto-HSCT in the Department of Hematology of Henan Cancer Hospital from September 2010 to November 2017 were retrospectively analyzed, the clinical curative efficiency was summarized and the related factors were analyzed. RESULTS: The curative efficiency of the patients before transplantation was 9(22.5%) with complete remission(CR), 5(12.5%) with very good partial remission(VGPR), 26(65%) with partial remission(PR), respectively, one of them was PR after 3 recurrences. The curative efficiency after transplantation was 22(55%) with complete remission(CR), 12(30%) with very good partial remission(VGPR), 6(15%) with partial remission(PR), respectively. And 2 cases were CR after double transplantation. Median follow-up time was 28.4 (3.1 to 88) months,15 cases presented disease progression, 7 cases were dead, 3-year estimated progression-free survival(PFS) and overall survival(OS) rate were 45.1% and 82% respectively. Unvariate analysis showed that the OS was affected by ISS stage (P<0.05), CR and VGPR (P<0.05) after transplantation; PFS was affected by ISS stage (P<0.01), before transplantation induction therapy (27 cases with bortezomizomi or thalidomide) (P<0.05), disease risk stratification (6 cases in high risk group) (P<0.05) , CR and VGPR (P<0.05) before transplantation, CR and VGPR (P<0.01) after transplantation. Cox multivariate regression analysis showed that the independent prognostic factors for OS were ISS stage, CR and VGPR after transplantation; the independent prognostic factors for PFS were the CR, VGPR, ISS stage after transplantation and induction therapy before transplant. CONCLUSION: Auto-HSCT can improve the clinical efficacy and survival rate of MM patients; ISS stage, CR and VGPR after transplantation are independent prognostic factors for OS and PFS, and induction therapy before transplantation is also an independent prognostic factor for PFS.

AB - OBJECTIVE: To investigate the expression of interleukin-17(IL-17)and matrix metalloproteinase-13 (MMP-13)in bone marrow biopsy of patients with multiple myeloma(MM)and its clicnical siginficonce. METHODS: The expressions of IL-17 and MMP-13 in bone marrow biopsy of 47 patients with MM and 10 normal persons as controls were determined with immunohistochemical method. RESULTS: The mean optical density of IL-17+ and MMP-13+ in MM group was significantly higher than that in control group(P<0.01). The mean optical density of IL-17+ and MMP-13+ positive expression in osteolytic lesions of MM group was significantly higher than that in patients without osteolytic lesions. The expression of NF-kappaB p65+ in MM group was significantly higher than that in control group(P<0.05); however the IL-17 level positively correlated with MMP-13 expression level(r=0.514) in MM group. The levels of IL-17 and MMP-13 in patients with ineffective treatment were very significantly higher than those in patients with effective trealment(P<0.01). CONCLUSION: The expression of IL-17 and MMP-13 in MM patients is significantly higher than that in the control group,and the expression of IL-17 and MMP-13 closely relate with MBD,which may be involved in the pathogenesis of MBD through NF-kappaB pathway,while the IL-17 and MMP-13 may serve as potential indicator for evaluation of therapeutic efficacy.

AB - OBJECTIVE: To investigate the effect of Luteolin on proliferation and cell death of human multiple myeloma cell line RPMI-8226 and its mechanisms. METHODS: The effect of Luteolin on the growth of human multiple myeloma cell line RPMI-8226 was detected by CCK-8, and then the minimal effective concentration was determined and was used to treat RPMI-8226 cells. The effects of luteolin and chloroquine on expression of cleaved-caspase 3 and LC3 in RPMI8826 cells was detected by Western blot. RESULTS: The luteolin significant inhibited RPMI-8226 cell proliferation in a dose-dependent manner. Treatment with lutedin 40-80umol/L for 24 hours and luteolin 20-80umol/L for 48 hours inhibited RPMI-8226 cell proliferation in a dose-dependent manner (24 h, r= -0.983; 48 h, r= -0.985). After treatment with lutelin 20umol/L for 48 h, the expression of cleaved caspase3 and LC3 II/I in RPMI 8826 cells significantly increased; after treatment with chloroquine at the same time, the expression of cleaved-caspase 3 and LC3 II/I significantly decreased. CONCLUSION: Luteolin inhibits the proliferation of RPMI-8226 cells by inducing the pathways of both apoptosis and autophagy, moreover the actions of apoptosis and autophagy are interactive or/and promotive each other. PMID- 30295263 TI - [Variation of STAT3 Gene in Myleproliferative Neoplasms and Its Significance]. AB - OBJECTIVE: To detect the mutation and single nucleotide polymorphisms of STAT3 gene in the patients with myeloproliferative neoplasms (MPN), and to analyze the correlation between STAT3 gene and the subtypes of MPN. METHODS: A total of 147 patients with MPN were selected, including 28 patients with polycythaemia vera (PV), 46 patients with essential thrombocythemia (ET), 10 patients with primary myelofibrosis (PMF), and 63 patients with chronic myeloid leukemia (CML); and 88 healthy persons were used as normal control. DNA of all cases was extracted from bone marrow or peripheral blood, and JAK2V617F gene mutation was detected by allele-specific PCR, then 23 exons of STAT3 gene were amplified by PCR. Mutation and single nucleotide polymorphism of Rs2293152 of STAT3 gene were identified by DNA sequencing. RESULTS: STAT3 gene mutation was found in 8 patients with CML. The mutation rate was 12.7%. the missense mutation(S629T)as found in 3 cases, the synonymous mutation was found in 5 cases (Q469Q 3 cases, G618G 2 cases). One case had mutations at the both sites of S629T and G618G. No mutation of STAT3 gene was found in the normal control group. Rs2293152: detection showed that the G allele of CML group was significantly higher than that of normal control, PV, ET and PMF group (P<0.01), suggesting that the patients with Rs2293152 G allele were more likely to develop CML. The C allele of PV, ET and PMF group was significantly higher than that of CML group (P<0.05), suggesting that the patients with Rs2293152 C allele were more likely to develop PV, ET and PMF. The G allele fiequency of JAK2V617F-negative group was significantly lower than that of the normal control and JAK2V617F positive group (P<0.01), suggesting that the Rs2293152 G allele may be a factor protecting against JAK2V617F mutation. CONCLUSION: In MPN patients, STAT3 gene is unstable and prone to mutation. The different alleles of the Rs2293152 locus of the STAT3 gene are relates with different subtypes and JAK2V617F-negative MPN.

AB - OBJECTIVE: To explore clinical features and laboratory data of glucose-6 phosphate dehydrogenase(G6PD)deficiency and to investigate the relationship between them. METHODS: Clinical data of 43 patients with G6PD deficiency was analyzed, the statistical method was applied to investigate the relationship between clinical features and laboratory data. RESULTS: Among 43 patients,neonatal jaundice occurred as the first symptom in 10 cases,while acute hemolytic anemia occurred as the first symptom in 23 cases. The major clinical symptoms of G6PD deficiency included icteric skin and/or sclera,dark urine,fever,gastrointestinal symptoms,fatigue and lethargy. Symptoms of 26 patients were caused by obvious inducement,including fava beans(61.5%),infection(34.6%)and miocardial infarction(3.8%). All of 43 patients showed decreased G6PD activity,while the level of their indirect serum bilirubin(IBIL)was positively correlated with reticulocyte percentage(Ret%,r=0.5881,P=0.013) and mean corpuscular volume(MCV,r=0.6854,P=0.0024). Patients with neonatal jaundice as the first symptom,showed higher level of Ret%(P<0.01)and MCV(P<0.001)and low RBC count(P<0.01)and low Hb level(P<0.01). as compard with patients with acute hemolytic anemia as first symptome. CONCLUSION: Neonatal jaundice and acute hemolytic anemia are common clinical features of G6PD deficiency. Laboratory results of IBIL,Ret% and MCV have auxiliary value to evaluate the severity of hemolysis induced by G6PD deficiency. Patients with neonatal jaundice as their first symptom show more severe hemolysis than those only suffered from acute hemolytic anemia.

CONCLUSION: The patients with aplastic anemia have significantly abnormal T lymphocyte subsets, there is a certain correlation between the serum TNF-alpha, IFN-gamma and sFas levels with aplastic anemia, each index can reflect the disease severity, and the changes of T lymphocyte subsets has important influence on the clinical prognosis of the patients. PMID- 30295269 TI - [Oxidative Stress Status and Its Effect on Regulation of Hepcidin in Patients with HbHCS]. AB - OBJECTIVE: To investigate the oxidative stress status and its effects on hepcidin in patients with hemoglobin H Constant Spring disease (HbH-CS). METHODS: A total of 35 patients were enrolled in the study, including 15 splenectomized cases and 20 non-splenectomized cases. 20 healthy volunteers were selected as controls. Serum superoxide dismutase (SOD), malondialdehyde (MDA), glutathione (GSH), oxidized glutathione (GSSG) levels, erythropoietin (EPO), serum free transferrin receptor (sFTR), growth differentiation factor 15 (GDF15) as well as the level of hepcidin were detected. Correlation analysis and multiple factor regression analysis were performed to investigate the factors affecting the iron metabolism and erythropoiesis. RESULTS: Compared with healthy control, the SOD and GSH levels in patients with HbHCS decreased, while MDA and GSSG levels increased. The levels of SOD, MDA, GSG and GSSG were not significantly different between the patients with splenectomy and those without splenectomy. Correlation analysis showed that inpatients with HbHCS, EPO, sFTR and GDF15 correlated negatively with SOD level and positively with MDA level. EPO and sFTR levels negatively correlated with Hepcidin. CONCLUSION: Excessive oxidative stress is present in patients with HbHCS, and hepcidin is inhibited by the upregulation of EPO and sFTR, and hence involved in iron overload in patients.

AB - OBJECTIVE: To evaluate the performance of thromboelastography (TEG) to monitor in vivo blood coagulation status and the efficacy of antiplatelet aggregation drugs in the patients with coronary heart disease (CHD) after oral anticoagulation. METHODS: Seventy one CHD patients were enrolled in CHD group and 380 healthy persons with normal TEG were enrolled in the control group. After admission, all CHD patients were administrated with routine anti-platelet aggregation drugs at a clinically recommended dose. Then, TEG was applied to monitor the basic blood coagulation indexes, such as R value, K value, alpha angle, MA value, CI value and a series of related indexes on platelet inhibition. RESULTS: Above 80% of the basic blood coagulation indexes in TEG were within normal reference range in the CHD group. the R value, MA value, alpha angle and CI value in the CHD group were not significanly different, from that in the control group, but the K value significantly increased (P<0.05). Compared with the control group, relatively higher ratio of male was included in the CHD patients at much older age (P<0.05), 83.1% of the CHD patients achieved significant anti-platelet aggregation effect (platelet inhibition rate>50%). Other antiplatelet aggregation indexes, MAADP, MAck and MAA suggested a 9.86%, 4.23% and 12.68% risk of thrombogenesis, respectively. Among all the related antiplatelet aggregation indexes, MAck showed the strongest correlation with age (correlation coefficient, 0.111), and ADP% most highly correlated with body mass (correlation coefficient, 0.160). CONCLUSION: TEG results can provide valuable coagulation information for clinicians, thus certainly guiding in the treatment for CHD patients receiving anti-platelet therapy. Moreover, the application of TEG can also provide accurate information for further individualized treatment of CHD patients, which would funther inprove the safety of anti-thrombotic therapy. PMID- 30295273 TI - [Effects of Stored Apheresis Platelet Apoptosis on Aggregation Function]. AB - OBJECTIVE: To investigate the effects of storage lesion in apheresis platelets on platelet apoptosis and the changes of aggregation function, and analyze the relationships between the apoptosis and aggregation function. METHODS: Platelet samples were collected from 10 healthy donors with O blood group. Firstly, the effects of storage lesion in platelets on the platelet apoptosis were detected by flow cytometry. Then, using a multiplate analyzer, individual-donor Plt aggregation response to stimulation by the agonists ADP, Collagen, TRAP and ASPI was examined. Finally, the relationships between its apoptosis and aggregation function was analyzed by correlation regression analysis. RESULTS: By flow cytometry it was found that with the prolonging of storage time, the apoptosis ratio of platelets significantly increased in a time-dependent manner, the apoptosis rates of platelets on 2nd, 5th and 8th day were (2.87+/-0.31)%, (11.08+/-1.54)% and (27.99+/-2.76)% respectively (P<0.01). Compared with Day 2 platelets, the d 5 platelets stored for 5 d significantly decrease the aggregation response to stimnlation of collagen, TRAP, and ASPI. Compared with platelets stored for 5 d, platelets stored for 8 d significantly decreased the aggregation response to stimnlation of collagen, TRAP and ASPI (P<0.01). However, when stimulated by ADP, the aggregation response was similar among Day 2, Day 5 and Day 8 platelets. The rate of the aggregation function was also declined significantly when stimulated by collagen, TRAP, and ASPI, but not ADP. Further regression analysis showed that the aggregation function of apheresis platelet negatively correlated with the apoptosis (r=-0.9497, r=-0.9527, r= -0.9707 and r= -0.9352 respectively), and the correlation is very strong. CONCLUSION: With the prolonging of storage time, the apoptosis ratio in platelets significantly increased. The aggregation function also is declined significantly when stimulated by collagen, TRAP, and ASPI, but not ADP. The aggregation function of apheresis platelets closly correlats with the apoptosis.

AB - OBJECTIVE: To better define the effect of JAK2V617F mutant allele burden on clinical presentation of patients with essential thrombo cythamia (ET), especially thrombosis. METHODS: Two ml of heparin anti-coagulated bone marrow was collected from 229 ET cases, who were diagnosed and treated in the First People's Hospital of Yunnan Province during 2013.10 to 2016.12. and then the mononuclear cells were separated by Red Blood Cell Lysis Buffer, genomic DNA was extracted from mononuclear cells by using a commercial DNA isolation kit and amplified by allele specific polymerase chain reaction (PCR). According to the size of molecular weight, the amplified products were separated by electrophoresis on a 2% agarose gel to screen the JAK2V617F mutation, then the JAK2V617F mutation burden was detected by real-time polymerase chain reaction (RT-PCR) in 120 patients with JAK2V617F mutation. Meanwhile, these samples were sequenced in order to verify the accuracy of the PCR screewing. RESULTS: ET patients with thrombotic events had significantly higher JAK2V617F allele burden than those without thrombosis (23.2% vs 14.2%) ( P<0.05). Meanwhile, ET patients showed increased JAK2V617F allele burden in the group with higher leukocytosis (WBC > 10*109/L) (P<0.001) and hemoglobin (> 150 g/L) (P<0.05). JAK2V617F mutation burden in 17 patients with splenomegaly was higher than that in 45 patients without splenomegaly (28.1% vs 11.8%) (P<0.05). but the JAK2V617F mutation burden was regatively correlated with platelet count (P<0.05). On the other hand, no correlation was found between JAK2V617F mutation burden and sex (P > 0.05). Univariate analysis showed that the JAK2V617F allele burden did not affect survival. Multivariable analysis showed that prognostic variable including WBC counts, hemoglobin level, age, sex, and splenomegaly not affected survival, (P > 0.05). CONCLUSION: The clinical presentations of ET patients, such as WBC counts, hemoglobin level and splenomegaly, are influenced by the JAK2V617F mutation burden. ET patients with thrombotic events has significantly higher JAK2V617F allele burden than those in ET palients without thrombosis.JAK2V617F mutation burden has no relations with sex and age..

AB - OBJECTIVE: To investigate the efficiency and safety of treating Epstein-Barr virus (EBV) infection of acute graft versus host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) by EBV specific cytotoxic T lymphocytes (EBV-CTL). METHODS: The Clinical characteristics, therapeutic efficacy and safety of 12 patients with EBV infection treated by EBV-CTL infusion after allo-HSCT in Department of Hemahlogy of Aero Space Center Hospital between Jan 2015 and May 2017 were analyzed retrospectioely. RESULTS: Our of 12 cases received EBV-CTL infusion after transplantation, 9 did not received Rituximab therapy due to the active infection, 4 cases including 3 received Ritaximab progressed into posttransplantation lymphoroliferetive disease (PTLD). The median time of EBV infection was 47 (22-71) days, median time of antivirus therapy before tramplantation was 10 (8-33) days, median time of first CTL infusion was 59(34-86) days after transplatation. The 43 cases-time CTL infusion was performed smoothly, no related harmful evnts occoured, no progression of GVHD was observed. After the first course of infusion, complete remission (CR), Partial remssion (PR) and no remssion (NR) were obtained in 9, 1 and 2 patients respectively, the relapse was observed in 4 patients who then received the socond course of infusion and all reached CR, the patient in PR did not reathed CR finally and died of GVGD at 5 months after transpplantation . Only 1 out of 2 cases of NR obtained CR, another 1 still was in NR, and died of transplantation related infection at 5 months after transplantation. 4 cases of PTLD were all cared. CONCLUSION: Preliminary results of this study suggest that EBV-CTL infusion is safe for the EBV infection combined with acute GVHD after all-HSCT. However, a further larger scale clinical studies are needed to prove the efficiency. PMID- 30295278 TI - [Effect of Shh and BM-MSC Synergism on the Proliferation of Hematopoietic Stem Cells]. AB - OBJECTIVE: To study the effect and mechanism of shh and mesenchymal stem cell(MSC)synergism on the proliferation of hematopoietic stem cells in noninvasive co-culture system in vitro. METHODS: The mesenchymal stem cells were cultured in vitro,CD34+ cells were sorted by mini MACS magnetic bead separator,flow cytometry was used to identify the purity of 2 cells. CD34+ cells and MSCs were seeded to upper and low of transwell respecibely for non-contact coculture,and add exogenous shh protein for intervenece. The number of MSCs and HSCs,the total amount of RNA,the expression of ki67 and Tie-2 mRNA of HSC,the expression of VEGF and Ang-1 mRNA of MSC were detected for investigating the condition of cell proliferation and the expression of angiogenic factors. RESULTS: The total number of cells,the total amount of RNA and the relative expression of ki67, Tie-2, VEGF and Ang-1 in non-contact co-culture group increased and showed the following trends on the 7th day:the above-mentioned indexes in group MSC + HSC, group shh + HSC were higher than those in group HSC, while those in MSC + shh + HSC Group was higher than those in MSC + HSC and shh + HSC group. CONCLUSION: Angiogenic factors help MSC to proliferate HSC and amplify the CD34+ hematopoietic stem/progenitor cells by shh and MSC synergism in vitro coculture system which may be related with angiogenic factors.

AB - OBJECTIVE: To investigate the effects of exosomes derived from miR-486 gene modified umbilical cord mesenchymal stem cells (UC-MSCs) on biological characteristics of rat cardiomyocytes. METHODS: The human umbilical cord mesenchymal stem cells (UC-MSCs) were isolated and cultured, then the immunophenotypes and ability of osteogenic and adipogenic differentiation of UC MSC were identified. The structure of exosomes was observed by electron microscopy; the effect of exosomes on cell migration was detected by transwell cell migration test; the miR-486 high expression of UC-MSC was mediated by using recombinant adenovirus vector, moreover the UC-MSC with high expression of miR 486 were identified by qPT-PCR. The exosomes were isolated from cell culture supernatant by ultracentrifugation and the miR-486 expression level of UC MSC exosomes was detected by qRT-PCR. The effect of exosomes on the proliferation of cardiomyocytes was evaluated by Dye670 marking. The H2O2-induced cardiomyocyte apoptosis model was established, and the effect of exosomes on apoptosis of cardiomyocytes was detected by flow cytometry with Annexin V/PI double staining. RESULTS: The exosomes derived from UC-MSCs had the diameter between 40-100 nm and double membrane stracture. The recombinant adenovirus could effectively mediate the expression of miR-486 in UC-MSC, and the expression level of miR-486 in exosomes of miR-486-modified UC-MSC significantly increased. The exosomes with miR-486 high expression possessed the pro-proliferation and pro-migration effects on cardiomyocytes, moreover the preventive effect on apoptosis of cardiomyocytes. CONCLUSION: The exosomes derived from UC-MSC and accompamied by high expression of miR-486 can promote the proliferation and migration of cardio myocytes, yet can prevent the apoptosis of cardiomyocytes. PMID- 30295280 TI - [Mesenchymal Stem Cells Stimulated by Growth Factors Release Exosomes with Potent Proangiogenic Activity]. AB - OBJECTIVE: To explore the proangiogenic activity of exsomes released by human umbilical cord mesenchymal stem cells (MSCs) stimulated by erythropoietin and platelet-derived growth factor BB (PDGF-BB). METHODS: Human umbilical cord derived MSCs were seeded and maintained in culture overnight. The media were then replaced by alpha-MEM containing EPO (1 U/ml) and/or PDGF-BB (50 ng/ml), and the culture was maintained for 72 hours. The exosomes from the culture supernatants were isolated with a routine ultra-catrifagation method. Flow cytometric analysis was performed to identify the origin of the exosomes, and their morphological features were observed by using a transmission electron microscopy. The exosomes were added at a concentration of 10 ug/ml into the culture system of human umbilical cord vein endothelial cells. MTT assay was used to evaluate the proliferative status. The Matrigel assay was used to observe the formation of net work structures which were calculated after culture for 12 hours. RESULTS: Flow cytometric analysis showed that microparticles released by human umbilical cord MSCs expressed CD9, CD63 and CD81, which was in accordance with the surface molecular features of exosomes. Under an electron microscope, the exosomes took the featured cystic shape. The protein contents of exosomes released by untreated, EPO-stimulated, PDGF-BB-stimulated and EPO plus PDGF-BB stimulated MSCs (108 cells) were 256+/-124 ug, 1021+/-392 ug, 830+/-265 ug and 2207+/-733 ug, respectively. The results revealed that MSCs treated by EPO and PDGF-BB released significantly higher amounts of exosomes (P<0.01). MTT assay proved that the exosomes from EPO and PDGF-BB treated MSCs had more potent proliferation promoting activity on human umbilical cord vein endothelial cells than those from untreated MSCs. The Matrigel assay showed that the numbers of capillary-like structures in untreated, EPO-, PDGF-BB and EPO plus PDGF-BB-treated groups were 2.6+/-0.84, 4.6+/-1.57, 4.2+/-0.78 and 6.3+/-1.34 per high power objective. Treatment with EPO or PDGF-BB dramatically enhanced the numbers of capillary liue structure, compared with that of untreated group (P<0.01) and those in EPO and PDGF-BB combination group was significantly greater than those of EPO or PDGF-BB group (P<0.01). CONCLUSION: EPO and PDGF-BB can stimulate MSCs to release exosomes with more potent proangiogenic activity.

AB - OBJECTIVE: To explore the effects of lentiviral-mediated CXC chemokine receptor 4(CXCR-4)gene over-expression on the homing capacity of mesenchymal stem cells(MSC)in vivo. METHODS: The MSC overexpressing CXCR-4 were constructed by using the lentiviral vector-mediated mouse MSC overexpressing the CXCR-4 gene. The BALB/c mice were divided into 3 group: simple radiation group(TBI)in which mice exposed to total body irradiation, then were infused with normal saline; EGFP-MSC group in which mice were infused with MSC(5*105)transducted by EGFP via tail vein after TBI; and CXCR-4-MSC group in which mice were infused with MSC (5*105) simultaneously carraying EGFP and CXCR-4 gene via tail vein after TBI. The mice were sacrified at 24 hours after infusion, the frozen sections were prepared to detect the distribution of infused MSC. Furthermore, the numbers of MSC homing into spleen and bone marrow was detected by flow cytometry, and the level of stromal cell-derived factor-1(SDF-1) was detected by ELISA. RESULTS: The frozen section showed that the CXCR-4 over-expression could significantly enhance the efficacy of MSC homing into lung, liver and spleen; the flow cytonetry detection slowed that the number of over-expressed CXCR-4 MSC homing into spleen and bone matrow was sigmificantly higher than that in EGFP-MSC group(P<0.05), the ELISA showed that the SDF-1 level in peripheral blood and bone marrow after 24 hours of irradiation significantly incrtaoed (P<0.05), moreover, the SDF-1 level increase was associcted with horming efficacy of MSC with CXCR-4 overexpression. CONCLUSION: overexpression CXCR-4 gene mediated by lentiviral vector can prmote the efficacy of MSC homing into spleen and bone marrow. PMID- 30295282 TI - [Diagnostic Values of Procalcitonin, C-reactive Protein and Interleukin-6 in Hematological Diseases with Bacterial Infection]. AB - OBJECTIVE: To evaluate the diagnostic values of procalcitonin(PCT), C-reactive protein(CRP) and interleukin-6 (IL-6) in patients suffered from hematological diseases with bacterial infection, and to provide further evidence for clinical application. METHODS: A total of 3631 blood cultures, serum levels of PCT and CRP and IL-6 (n=1587) from the inpatients from 2014-01-02 to 2018-01-27 were retrospectively analyzed. The patients were divided into positive (n=208) and negative blood culture (n=3423) groups. Positive blood culture group were redivided into gram-positive (n=34) and gram-negative (n=174) subgroups. The values CRP, PCT and IL-6 were compared respectively in these groups. The data were analyzed by using R 3.4.4 language. RESULTS: The medians of PCT values in positive and negative blood culture groups were 0.41(0.04-103.34) MUg/L and 0.20(0.02-200) MUg/L(P<0.001) respectively. The medians of CRP values in positive and negative blood culture groups were 9.49(0.1-370) mg/dl and 5.42(0-370) mg/dl (P<0.001) respectively. The medians of IL-6 values in positive and negative blood culture groups were 186.1(2.0-5000, n=91) pg/ml and 52.65(1.5-5000, n=1496) pg/ml (P<0.001). The medians of PCT values in gram-positive and gram-negative groups were 0.20(0.05-93.83) MUg/L and 0.58(0.04-103.34) MUg/L (P=0.006) respectively. The medians of CRP value in gram-positive and gram-negative groups were 9.19(0.1 35.3)mg/dL and 9.49(0.1-370) mg/dl (P=0.300) respectively. The medians of IL-6 values in gram-positive and gram-negative groups were 83.01(5.61-1500, n=12) pg/ml and 208(2.0-5000, n=79) pg/ml (P=0.357). CONCLUSION: The PCT, CRP and IL-6 levels were significantly higher in the positive blood culture group than those in the negative blood culture group, so provide the effective early diagnostic markers for blood culture. PCT levels in gram-positive group were significantly higher than that in gram-negative groups, contributing to distinguish between the 2 groups. PMID- 30295283 TI - [Coagulation Properties for Whole Blood Stored at 4C]. AB - OBJECTIVE: To study the coagulation properties the refrigerated whole blood stored at 4C. METHODS: Ten units of whole blood were obtained from healthy volunteer donors and stored at 4+/-2C for 21 days. Samples were collected on the day after donation and on days 2, 4, 6, 8, 10, 14 and 21 for delection including complete blood count, electrolyte, APTT, PT, Fg, blood coagulation factors, and thromboelastography(TEG). RESULTS: The levels of Hb, WBC, Plt, sodium and potassium in each sample accorded with standard of storing whole blood. The level of Hb, WBC, Plt and Na+ decreased along with prolonging of storage time, while the K+ level increased along with prolonging of stored time, APTT and PT prolonged along with prolonging of thored time, PT>17 min at d 21, the Fg level change was no-obvious, The level of factor V and VIII decreased more than 50 % of baseline on d 6 and 4 respectively; the levels of factor II, VII, IX, X, XI, XII showed decreasing trend, but their levels were less than 40 % of baseline values at d 21. TEG test showed that no abnormalily of R value was found, the abnormal valnes of K and Angle were observed at d 21, the abnormal value of MA was observed at d 14. CONCLUSION: The whole blood stored for 10 days possesses normal coagulation function showing important significance for treatment of hemorrhage from war injury and surgical openation of heart and chest. PMID- 30295284 TI - [A Preliminary Study on the Expression of CD160 on NK Cells and Its Mechanism of Mediating NK Killing Effect]. AB - OBJECTIVE: To investigate the expression of CD160 on the surface of human natural killer (NK) cells and its possible relationship with hematological malignancies. METHODS: CD160 expression on human leukemia cell line NK92 cells was confirmed by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot. The proliferation characteristics and cell surface markers of this cell line were determined. Cytotoxicity of NK92 against 2 human myeloid leukemia cell lines, K562 and THP-1 was analyzed ex vivo. CD160 blocking antibody CL1-R2 was employed to clarify its role in NK cell mediated cytolysis. Then, the expression of CD160 on NK cells in peripheral blood from various patients with hematological malignancies were measured by flow cytometry. RESULTS: The mRNA and protein levels of CD160 expressions on NK92 cells were confirmed by RT-PCR and Western blot, respectively. The flow cytometry results demonstrated that the strong positive expression of CD160 could be detected on the NK92 cell surface. NK92 could effectively kill K562 and THP-1 cells, while the cytolysis effect was abrogated in the presence of CD160 blocking antibody CL1-R2. The high levels of HVEM were expressed on both target cells, but the HLA class I molecules were absent on K562. The expression of CD160 on CD3-CD56+ NK cells in peripheral blood from patients with acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL) and allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients was significant lower than that in the normal controls (P<0.05). CONCLUSION: The cytolysis function of human NK cells is mediated partially by CD160 molecule. The decrease of CD160 expression on NK cells from patients with various hematological malignancies implies that down-regulation of CD160 expression may be a novel mechanism of tumor immune escape.

AB - BK virus(BKV)associated hemorrhagic cystitis is one of the most common complications after hematopoietic stem cell transplantation(HSCT), which can increase the suffering, become time consuming and even life threatening. However, BKV infection has not attracted enough attention in clinical practice. Accurate BKV monitoring and effective clinical treatments are still in urgent need. In recent years, BKV-DNA monitoring has shown a significant clinical value in BKV associated hemorrhagic cystitis after HSCT. As for clinical treatments, traditional antivirus agent cidofovir is still to show promising effects, in the meantime, the virus-specific lymphocytes and other new therapies are continuously appearing. Here, the most recent advances on pathogenesis, treatment, virus monstoring and so on for BKV associated hemorrhagic cystitis after HSCT are reviwed. PMID- 30295286 TI - [Research Progress in Acute Hemolysis and Safe Blood Transfusion of Glucose-6 Phosphate Dehydrogenase Deficiency-Review]. AB - Glucose-6-phosphate dehydrogenase deficiency (G6PD) is one of hereditary diseases sariously influencing the human health. G6PD is characterized by wide distribution, high incidence, inducing the hemolysis, complex mechanism of hemolysis and common occurence in children and so on. The blood transfusion is most effective method for acute ouset of hemolysis, but the risk is more high, thereby it is necessary to guarante the safety of blood transfusion. In addition of the routine managementin blood transfusion and standard procedures, the basic rules and indicators of blood transfusion must be grasped, the blood preparations should be known well, the blood protection must be strengthened, and the measures of personalized psychologic interference must be drawn up carnestly and performed strictily so as to improve the therapeutic efficacy and safe of blood transfusion. Through the promotion and development of social pubbicity, elucation activities, preventive and control measures and medical levels, many patients have been freed from healthy problems as soon as possible. In this review, the research progress on acute hemolysis and safe blood transfusion in G6PD are summarized. PMID- 30295287 TI - [Mechanism and Its Countermeasure of Hypomethylating Agent Resistance in Patients with Myelodysplastic Syndrome--Review]. AB - Hypomethylating agents(HMA) currently are widely used in the treatment of myelodysplastic syndromes (MDS), provide a significant improvement in the treatment of MDS. However, resistance to HMA is an almost universal phenomenon. This review was focused on immune effects related to DNA methylation, and to explore the mechanism underlying HMA resistance involved in immune checkpoint pathways. However, the optimal role of checkpoint blockade therapy (CBT) and immune checkpoint pathways remain in HMA failure questionable. The better understanding of immune checkpoint pathways in resistance of HMA offers a compelling rationale to introduce CBT in patients as a novel treatment option. CBT is an established strategy in solid tumors with potential as an adjunctive therapy in hematologic malignancies, therefore, may alter the treatment landscape in MDS. The suitability and effectiveness of combining HMA with CBT need to be confirmed by the results of ongoing clinical trials, so as to find novel strategies to improve outcome after failure of HMA. PMID- 30295288 TI - [Research Progress on Ph-like Acute Lymphoblastic Leukemia--Review]. AB - Ph-like acute lymphoblastic leukemia (ALL) is a high-risk subtype of precursor B cell acute lymphoblastic leukemia (BCP-ALL) with a gene expression profile and a high frequency of IKZF1 gene alteration similar to that of Ph-positive ALL, which is a clinically and biologically heterogeneous subtype of BCP-ALL. The prognosis correlats negatively with age increasing. The incidence of this "Ph-like" subtype may be higher in young adults. Ph-like ALL is characterized by genetic alterations that activate cytokine receptor genes and kinase signaling pathways. Prospective studies are needed to determine if incorporation of tyrosine kinase inhibitor-targeting kinase alterations into intensive chemotherapy regimens will improve outcome of patients with Ph-like ALL. The research progress of Ph-like ALL is summarised in this review, including epidemiology, genetic alterations and treatment..

PMID- 30295289 TI - Replication Study: Intestinal inflammation targets cancer-inducing activity of the microbiota. AB - As part of the Reproducibility Project: Cancer Biology we published a Registered Report (Eaton et al., 2015) that described how we intended to replicate selected experiments from the paper "Intestinal Inflammation Targets Cancer-Inducing Activity of the Microbiota" (Arthur et al., 2012). Here we report the results. We observed no impact on bacterial growth or colonization capacity when the polyketide synthase (pks) genotoxic island was deleted from E. coli NC101, similar to the original study (Supplementary Figure 7; Arthur et al., 2012). However, for the experiment that compared inflammation, invasion, and neoplasia in azoxymethane (AOM)-treated interleukin-10-deficient mice mono-associated with NC101 or NC101[Formula: see text] pks the experimental timing of the replication attempt was longer than that of the original study. This difference was because in the original study the methodology was not clearly stated and likely led to the increased mortality and severity of inflammation observed in this replication attempt. Additionally, early death occurred during AOM treatment with higher mortality observed in NC101[Formula: see text] pks mono-associated mice compared to NC101, which was in the same direction, but more severe than the original study (Suppleme1ntal Figure 10; Arthur et al., 2012). A meta-analysis suggests that mice mono-associated with NC101[Formula: see text] pks have higher mortality compared to NC101. While these data were unable to address whether, under the conditions of the original study, NC101 and NC101[Formula: see text] pks differ in inflammation, invasion, and neoplasia this replication attempt demonstrates that clear description of experimental methods is essential to ensure accurate reproduction of experimental studies. PMID- 30295293 TI - Propensity-Matched Comparison of Vascular Closure Devices after Transcatheter Aortic Valve Replacement using MANTA versus ProGlide. AB - AIMS: Vascular and bleeding complications increase morbidity and mortality in transcatheter aortic valve replacement (TAVR). However, data regarding the efficacy and safety of the percutaneous vascular closure device, MANTA is scarce. METHODS AND RESULTS: We performed a retrospective, propensity score-matched study to compare vascular and bleeding complications in 325 consecutive patients who underwent TAVR using MANTA and ProGlide. The 1:1 propensity score-matching resulted in 111 matched pairs. For MANTA- versus ProGlide-treated patients, all cause mortality (0% vs. 4%, p=0.02), vascular complications (14% vs. 21%, p=0.21), and bleeding complications (18% vs. 33%, p=0.01) were observed. Access site vascular injury was significantly less frequent in patients who received MANTA versus ProGlide (8% vs. 17%, p=0.04). MANTA presented significantly lower hemoglobin decrease (16.4 vs. 20.0 g/l, p=0.04) and shorter hospital stay after TAVR (3.3 vs. 5.8 days, p=0.02). It also predicted fewer bleeding complications (OR: 0.44; 95% CI: 0.23 - 0.83; p=0.01). Moreover, significant decreases of all endpoints were not seen across the procedure date tertiles in the MANTA group. CONCLUSIONS: MANTA resulted in a significantly lower complication rate, especially for bleeding, than did ProGlide despite the operators' inexperience in the use of MANTA.

PMID- 30295297 TI - A near-infrared xanthene fluorescence probe for monitoring peroxynitrite in living cells and mouse inflammation model. AB - Peroxynitrite (ONOO-) plays important roles in the regulation of many physiological and pathological processes, and an increase in its levels is related to numerous diseases. Thus, accurate detection of ONOO- in physiological conditions is imperative for elucidating its functions. However, studies on high signal-to-noise-ratio (SNR) fluorescence imaging of ONOO-in vivo for its detection are currently lacking. Thus, a novel NIR xanthene fluorescence probe (NOF2) for the endogenous detection of ONOO- is designed and synthesized. The fluorescence of the NOF2 probe is pre-quenched by the hydroxyl protection group of diphenyl phosphinate. Additionally, the NOF2 probe exhibits good selectivity and sensitivity for ONOO- with a low detection limit of 0.40 MUM. Importantly, the NOF2 probe displays good performances for the detection of endogenous ONOO- not only in living cells but also in a mouse inflammation model. This demonstrates its great potential for applications involving the detection of ONOO both in vitro and in vivo to explore the roles of ONOO- in different physiological systems. PMID- 30295296 TI - Twenty Minute Moderate-Intensity Post-Dinner Exercise Reduces the Postprandial Glucose Response in Chinese Patients with Type 2 Diabetes. AB - BACKGROUND Postprandial hyperglycemia and glycemic fluctuations are significant cardiovascular disease risk factors for patients with type 2 diabetes. We investigated the effects of a single session of post-dinner moderate-intensity exercise on the postprandial glycemic response compared with a non-exercise condition in a study population of Chinese patients with type 2 diabetes. MATERIAL AND METHODS This randomized crossover self-controlled pilot study involved 29 patients with type 2 diabetes who participated in post-dinner exercise days using non-exercise days as a control. The interstitial glucose level was monitored using a continuous glucose monitoring system, with a standardized diet and medication. For the non-exercise control days, patients pursued normal daily activities but refrained from unusual strenuous physical activity. On the exercise days, participants walked on a treadmill for 20 minutes after dinner, with a heart rate reserve of 40%. RESULTS Post-dinner moderate intensity exercise reduced the 2-hour postprandial glucose spike, mean glucose level, and peak glucose level compared to the control condition. The cumulative glucose total area under the curve during 1-hour post-exercise was lower with exercise than under the control condition. The 12-hour standard deviation of blood glucose and the coefficient variation of glucose were significantly lower in the with exercise day compared to the control day, although the 12-hour mean amplitude of glycemic fluctuations did not reach statistical significance. No nocturnal hypoglycemia subsequently occurred on the exercise day. CONCLUSIONS A short session of moderate-intensity post-dinner exercise can improve postprandial hyperglycemia and glycemic excursions in Chinese patients with type 2 diabetes, with no potential hypoglycemia risk at a later period. PMID- 30295298 TI - All inorganic coordination polymers have been made possible with the m carboranylphosphinate ligand. AB - New examples of 1D coordination polymers (CPs) and complexes containing the purely inorganic carboranylphosphinate ligand [1-OPH(O)-1,7-closo-C2B10H11]- are reported. The reaction of Na[1-OPH(O)-1,7-closo-C2B10H11] salt with MCl2 (M = Mn, Co, Ni, Cu, Zn and Cd) in MeOH or EtOH leads to compounds 1-8. All compounds have been exhaustively characterized by analytical and spectroscopic techniques. X-ray analysis and spectroscopy characterization revealed the differences between the isolated compounds: 1D polymeric chains (CPs) with carboranylphosphinate ligand bridges have been obtained with MnII, CdII or ZnII centres, whereas compounds with low nuclearity have been isolated with CuII, CoII and NiII. No polymeric structures were obtained in the CoII and NiII complexes due to the higher affinity of these metals for water than that for the m-carboranylphosphinate and accordingly, these complexes generate supramolecular hydrophobic/hydrophilic structures. The reactivity of manganese polymer 1 with water leads to the breakage of the polymer with the formation of a new mononuclear compound 2, and that in methanol leads back to the initial polymer 1. However, the reactivity of polymer 1 with 2,2'-bpy maintains the core present in the initial polymer, leading to the CP 3, which in methanol/water medium produces species of lower nuclearity. The magnetic properties of the compounds studied show weak antiferromagnetic coupling.

SCU-63 has a honeycomb-like layer intercalated with protonated cyclic dipeptide cations. SCU-66 has a diamondoid framework containing cyclic dipeptide ligands. The two compounds show high proton conductivity on the order of 10-3 S cm-1 at 85 degrees C under 98% relative humidity. PMID- 30295300 TI - Engineered basement membranes: from in vivo considerations to cell-based assays. AB - Improvements in the physiological relevance of cell-based assays have been enabled by the development of various interdisciplinary methods. However, due to their complexity, in vivo structures such as basement membranes (BMs), which regulate the phenotype of adherent cells, are still difficult to mimic in vitro. The reconstruction of a physiologically relevant BM is crucially important to develop cell-based assays with the capacity for drug screening and disease modelling. Here, we review the biophysical and biochemical properties of BMs in vivo and their interactions with neighbouring cells. We discuss the current methods used to mimic BM functions in cell-based assays according to the type of targeted applications. In doing so, we examine the advantages and limitations of each method as well as exploring approaches to improve the physiological relevance of engineered or cell-derived BMs in vitro.

Of particular emphasis is a description of the development of reduced dimensional theories which can highlight chemical reactions that are likely to be of interest for more accurate quantum reactive scattering studies and new experiments. Furthermore, the reduced dimensional models allow for the development and testing of computationally inexpensive procedures that enable calculations to be performed on quantum effects in reactions of larger polyatomic molecules. PMID- 30295302 TI - Analysis of soluble or titanium dioxide derived titanium levels in human whole blood: consensus from an inter-laboratory comparison. AB - Exposure to titanium (Ti), via the ingestion of pigment grade Ti dioxide (TiO2), is commonplace for westernised populations. It may also occur as a consequence of metal ion leaching in subjects bearing Ti-containing implants. Accurate exposure analysis requires fit-for-purpose analytical methodology, especially for true measures of baseline levels. Inductively coupled plasma (ICP) techniques are, mainly, now used for bio-analysis of Ti. Since whole blood reference materials, certified for natural low levels of Ti, are not currently available, we undertook an inter-laboratory comparison of pooled human blood from fasted volunteers +/ low level (+~2.5 MUg L-1) or high level (+10-20 MUg L-1) spikes of soluble Ti or TiO2 particles. Seven established laboratories were enrolled to analyse the samples using ICP based techniques, which included at least one of ICP optical emission spectrometry (ICP-OES), high resolution ICP mass spectrometry (HR-ICP MS), triple quadrupole ICP-MS (ICP-MS/MS) or single quadrupole ICP-MS (SQ-ICP MS). Five laboratories diluted the blood for analysis whilst two performed acid digestion. Overall, we showed that the laboratories could, mostly, quantitatively detect modest levels of spiked Ti in blood. Markedly varying levels of Ti, however, were reported for the same baseline pooled sample (0.4-24.6 MUg L-1) and, in this study, specificity was poor for SQ-ICP-MS. Digestion of samples caused sample contamination compromising limits of detection and accuracy, whilst simple dilution had no such problem, and remained linear in response for spikes with ionic and TiO2 particles. We conclude that measuring baseline levels of Ti in whole blood is challenging but should be readily achievable down to 0.5-1.5 MUg L-1, if sample preparation avoids contamination and instrument techniques are used that negate polyatomic or isobaric interferences from the sample matrix. We also remind those relying upon Ti bio-analytical data for their experimental outcomes that (a) spiking and recovery experiments provide information only on linearity of detection but not at all on accuracy as this will not detect constant positive errors and that (b) biological standard materials for Ti generally contain high levels of the analyte and tend to mask baseline analytical errors. Caution may be required in interpreting the findings of some published Ti/TiO2 bio-exposure studies. PMID- 30295303 TI - A novel and accurate microfluidic assay of CD62L in bladder cancer serum samples. AB - We report a low-cost, sensitive, bead-based electrochemical immunoarray for soluble L-selectin (or CD62L protein), a potential biomarker for staging bladder cancer. We used a semi-automated modular microfluidic array with online antigen capture on superparamagnetic beads, which were subsequently delivered to a detection chamber housing multiple sensors. The assay was designed to accurately detect CD62L in diluted serum with a limit of detection (LOD) of 0.25 ng mL-1 and a dynamic range of 0.25-100 ng mL-1. The microfluidic array gave significantly better accuracy and higher sensitivity than a standard ELISA kit, which was shown to be subject to significant systematic error at high and low concentration ranges. 31 serum samples from patients with varying grades of bladder cancer and cancer-free controls were analyzed by the immunoarray and ELISA, and the CD62L levels correlated. This work establishes a new accurate assay for determining CD62L levels and highlights the potential of this protein as a biomarker for detecting locoregional progression of bladder cancer. PMID- 30295304 TI - The eta1-H-CHg agostic interactions in the mercury complexes of N-confused porphyrin. AB - Six four-coordinated complexes of the chemical formulae [Hg(2-N CH2COOCH2CH3-21-H NCTPP)X] with X = Cl (5), Br (6), I (7), [Hg(2-NCH3-21-H-NCTPP)Cl] (4) and [Hg(2 NCH2COOCH2C6H5-21-H-NCTPP)X] with X = Cl (8), I (9) are synthesized and structurally determined. The bond path for the weak eta1-H(17)-C(17)Hg agostic interactions between the Hg center and H(17) in complexes 4-9 was a through-space interaction from Hg to agostic carbon [C(17)] followed by a through-bond interaction from C(17) to an agostic proton [H(17)]. The magnitude of J[Hg-H(17)] [or the agostic upfield shift Deltadeltaago of the C(17)] for these complexes increases as the halide ligand varies from iodide to chloride, ranging from 33.2 Hz (or 14.3 ppm) for I- to 36 Hz (or 15.8 ppm) for Br- and 36.9 Hz (or 16.0 ppm) for Cl-. The plot of J[Hg-H(17)] for the agostic proton H(17) versus |Deltadeltaago| for the agostic carbon atom C(17) in compounds 3-9 was linearly expressed as J[Hg-H(17)] = 2.29 |Deltadeltaago| + 0.13. PMID- 30295305 TI - Sensitive fluorescence detection of heparin based on self-assembly of mesoporous silica nanoparticle-gold nanoclusters with emission enhancement characteristics. AB - Heparin (Hep) is widely used as a major anticoagulant in surgery. Simple and sensitive methods capable of quantitative detection of Hep are desired for better regulating its clinical use. Herein, a novel nanoassembly of amino-functionalized mesoporous silica nanoparticle-gold nanoclusters (MSN-AuNCs) with remarkable emission enhancement characteristics for sensitive fluorescence detection of Hep is developed. The electrostatic interaction between the positively charged amino functionalized MSNs and the AuNC-stabilizing surface ligands triggers the self assembly of MSN-AuNC nanocomposites which exhibit more than 5-fold fluorescence emission enhancement. However, the presence of negatively charged Hep inhibits the emission enhancement phenomenon due to the effective wrapping of Hep on the surface of MSNs, which blocks the interaction between AuNCs and MSNs. Benefitting from the remarkable emission enhancement and the competing binding of Hep, facile and ultrasensitive detection of Hep can be realized with a detection limit as low as 2 nM. Moreover, the successful application of the proposed method for detection of Hep in human serum samples shows promise for clinical applications. PMID- 30295307 TI - Chemical modification of enveloped viruses for biomedical applications. AB - The unique characteristics of enveloped viruses including nanometer size, consistent morphology, narrow size distribution, versatile functionality and biocompatibility have attracted attention from scientists to develop enveloped viruses for biomedical applications. The biomedical applications of the viral based nanoparticles include vaccine development, imaging and targeted drug delivery. The modification of the structural elements of enveloped viruses is necessary for the desired functions. Here, we review the chemical approaches that have been utilized to develop bionanomaterials based on enveloped viruses for biomedical applications. We first provide an overview of the structures of enveloped viruses which are composed of nucleic acids, structural and functional proteins, glycan residues and lipid envelope. The methods for modification, including direct conjugation, metabolic incorporation of functional groups and peptide tag insertion, are described based on the biomolecular types of viral components. Layer-by-layer technology is also included in this review to illustrate the non-covalent modification of enveloped viruses. Then, we further elaborate the applications of chemically-modified enveloped viruses, virus-like particles and viral subcomponents in biomedical research. PMID- 30295310 TI - Tender coconut water attenuates heat stress-induced testicular damage through modulation of the NF-kappaB and Nrf2 pathways. AB - Tender coconut water (TCW), a well-known plant beverage, has been used as a stress-relieving traditional medicine since ancient times. It is also used to treat various ailments of disease, including hepatic disorders, renal disorders, gastric disorders and reproductive disorders. However, the reasons for its effectiveness as a natural antioxidant as well as its testicular protective effects against whole body heat stress (HS)-induced oxidative imbalance remain to be revealed. The present study aimed to elucidate the protective efficacy of TCW on HS-induced testicular damage in a murine system and to explore the possible mechanism of action. Standardized liquid chromatography-mass spectrometry (LC-MS) was used to detect the presence of active components in TCW. Male Wistar rats were exposed to acute HS with or without TCW treatment to evaluate the degree of testicular damage, which was monitored through histological as well as biochemical analysis. Assessment of endogenous antioxidant response and the modulation of signaling pathways associated with inflammation were also subjected to immunofluorescence and flow cytometric evaluation. Acute hyperthermia caused an elevation of excess generation of oxygen radicals following the suppression of antioxidant capacity and augmentation of lipid peroxidation in murine testicles, which was restored by treatment with TCW. The results also demonstrated marked phosphorylation of IKKalpha/beta and IkappaBalpha following the activation of NF kappaB-guided pro-inflammation upon HS. TCW treatment reversed the HS-induced proinflammatory state through activation of the Nrf2-assisted antioxidant response, which restored the testicular damage. TCW provided competent scientific evidence to substantiate the claims for its use in the treatment of HS-induced inflammation and inflammation-mediated testicular damage. PMID- 30295311 TI - Determination of nitrite ions in environment analysis with a paper-based microfluidic device. AB - A new microfluidic paper-based analytical device, a (Ag-MUPAD)-based chemiresistor composed of silver ink, has been developed for the selective, sensitive, and quantitative determination of nitrite ions in environmental analysis. The silver ink acts as an efficient transducer in terms of resistance changes due to nitrite initiating a diazo reaction and further reacting with the ink. The silver ink is synthesized onto the MUPADs by pulsed light sintering from silver nanoparticles, a mixture of silver nanowires and nanoparticles. The resistance changes show two linear response ranges to nitrite in the concentration ranges of 1.0 * 10-8 M to 5.0 * 10-6 M and 1.0 * 10-5 M to 3.2 * 10 3 M, with a limit of detection of 8.5 * 10-11 M (S/N = 3). The sensor displays a wider linear range, a lower detection limit, a higher stability, high selectivity, low-volume sampling, and disposability for nitrite with respect to other nanoparticle- and paper-based sensors. The characterization of silver ink was verified by SEM, EDS, and IR studies, and the sensing mechanism is discussed. In addition, this paper-based sensor has been successfully employed to determine the nitrite content in tap, river and lake water samples. PMID- 30295312 TI - Interleukin-10 gene polymorphisms and chronic periodontitis susceptibility: Evidence based on 33 studies. AB - The purpose of the meta-analysis was to investigate the potential association of interleukin-10 (IL-10) polymorphisms with susceptibility to chronic periodontitis (CP). A total of 33 studies involving 3487 cases and 4356 controls were identified through a search of multiple electronic databases (last search was updated on 19 July 2018). Three single nucleotide polymorphisms (SNPs) were included in the meta-analysis: -1082A>G(rs1800896), -819C>T(rs1800871), and 592C>A(rs1800872). Odds ratios (ORs) and their 95% confidence intervals (CIs) using allele, dominant, and recessive genetic models were computed to assess the strength of the association. The -1082A>G(rs1800896) polymorphism was found to be associated with decreased CP risk in both Caucasians and Latinos under the dominant model. The -819C>T(rs1800871) and -592C>A(rs1800872) polymorphisms were both associated with increased CP risk in Latinos under the allele and dominant models. In Asians, no associations were observed for any of the polymorphisms under all comparison models. The present meta-analysis suggests that the 1082A>G(rs1800896) polymorphism might be a protective factor for CP in both Caucasians and Latinos, but the -819C>T(rs1800871) and -592C>A(rs1800872) polymorphisms might contribute to CP pathogenesis in Latinos. PMID- 30295313 TI - Developmental trajectories of adaptive behavior in autism spectrum disorder: a high-risk sibling cohort. AB - BACKGROUND: Children with autism spectrum disorder (ASD) often experience impairments in adaptive behavior. METHODS: Developmental trajectories of adaptive behavior in ASD were examined in children from high-risk (siblings of children diagnosed with ASD, n = 403) and low-risk (no family history of ASD, n = 163) families. Children were assessed prospectively at 12, 18, 24, and 36 months of age using the Vineland Adaptive Behavior Scales and underwent a blind independent diagnostic assessment for ASD at 36 months of age. RESULTS: The semi-parametric group-based modeling approach using standard scores on the Adaptive Behavior Composite revealed three distinct developmental trajectories: (a) Group 1 (21.2% of sample) showed average performance at 12 months and a declining trajectory; (b) Group 2 (52.8% of the sample) showed average performance at 12 months with a slightly declining trajectory; and (c) Group 3 (26.0% of the sample) showed a higher level of adaptive behavior at 12 months and a stable trajectory. The Mullen Scales of Early Learning Early Learning Composite and the Autism Observation Scale for Infants total score at 6 and 12 months predicted trajectory membership. CONCLUSIONS: The results emphasize heterogeneous development associated with ASD and the need for interventions tailored to individual presentations. PMID- 30295314 TI - Long noncoding RNA Gm6135 functions as a competitive endogenous RNA to regulate toll-like receptor 4 expression by sponging miR-203-3p in diabetic nephropathy. AB - We aim to explore the relationship between Gm6135 and diabetic nephropathy. We detected the relative expression levels of Gm6135 and toll-like receptor 4 (TLR4) in diabetic nephropathy mice and high-glucose-cultured mouse mesangial cells SV40 MES-13 by the quantitative reverse transcription-polymerase chain reaction (qRT PCR) and western blot detection. Cell proliferation and apoptosis were detected after small interfering RNA (siRNA) interference or plasmid overexpression of Gm6135/TLR4, and bioinformatics method was used to predict and screen miR-203 as an intermediate factor. Through dual-luciferase reporter gene, RNA pull-down, qRT PCR, and western blot, the binding relationship between Gm6135, miR-203-3p, and TLR4 was confirmed. The possibility of the competing endogenous RNA mechanism was demonstrated by cell localization assays and rip assays. Finally, the proliferation of mouse mesangial cells SV40-MES-13 was detected after mimics and inhibitor of microRNA, which were reversed with TLR4 overexpression and siRNA. The results showed that the relative expression levels of Gm6135 and TLR4 in the kidney and high-glucose-cultured mouse mesangial cells of diabetic nephropathy mice increased significantly. Overexpression or downregulation of Gm6135/TLR4 significantly affected the proliferation and apoptosis of mouse mesangial cells. Gm6135 upregulates TLR4 by competitively binding to miR-203-3p. PMID- 30295315 TI - Quantitative colocalization analysis of DNA delivery by PEI-mediated cationic polymers in mammalian cells. AB - : Although cationic polymers are widely used for DNA delivery, the relationship between the properties of the formed complexes and their biological activity is not fully understood. Here, we propose a novel procedure consisting of superresolved images coupled with quantitative colocalization to analyse DNA release in living cells. This work compares the different workflows available in a quantitative colocalization study of DNA delivery using polyethylenimine as transfection reagent. A nimble workflow with deconvolution in three-dimensional images was developed. Among the different colocalization coefficients, Manders' colocalization coefficient was the best to track the complexes. Results showed that DNA/polyethylenimine complexes were tightly interacting at the time of transfection and their disassembly was observed between 2 and 10 h after their uptake. Heterogenicity was found in the intracellular fate of each complex. At 24 h, some complexes were still present underneath the nuclear envelope. Overall, this study opens the door for particle tracking assessment with three-dimensional imaging at intracellular level. LAY DESCRIPTION: DNA delivery technologies in living cells are of high relevance in the biotechnology field. The transient expression of a gene of interest enables the production of a wide range of new therapeutic candidates for clinical purposes. However, the introduction of an exogenous DNA construct into a cell culture requires the use of certain vehicles that protect the DNA from host cell DNases and deliver it into the cell nucleus. From the different systems available, polyethylenimine (PEI) has been extensively used in transient gene expression strategies for the last three decades. However, the intracellular fate of the formed DNA/PEI complexes and the DNA release from the complexes is still poorly understood. In this work, we propose the application of combined superresolved images through mathematical deconvolution to colocalization studies of DNA/PEI complexes evolution in living mammalian cell cultures. Both specimens were covalently labelled with Cy3 and Cy5 dye, respectively, and the kinetics of its disassembly process within the cells was tracked over the time. Because of the specific features of the formed-complexes, a comparative study of the different colocalization coefficients was performed towards optimizing the analysis of these particles with confocal microscopy. Besides, the 3D imaging of the process allowed the direct visualization of a partial DNA/PEI complexes disassembly and the location of those complexes underneath the nuclear envelope during the cell production phase (24 h after the uptake). PMID- 30295316 TI - Vitamin D attenuates human gingival fibroblast inflammatory cytokine production following advanced glycation end product interaction with receptors for AGE. AB - BACKGROUND AND OBJECTIVES: Vitamin D [1,25(OH)2 D3 or 1,25D3] is critical in musculoskeletal health, inflammation, immune response, and glucose metabolism. Patients with vitamin D deficiency may be at higher risk of diabetes and periodontitis. Diabetic patients exhibit exacerbated inflammation and more periodontal destruction. Advanced glycation end products (AGEs), formed during diabetic hyperglycemia, activate inflammatory pathways in periodontitis. Human gingival fibroblasts (HGFs) express receptors for AGEs (RAGEs) and can contribute to inflammation. OBJECTIVES: Determine whether glycated human serum albumin (G HSA) augments HGF IL-6 and IL-8 production, and whether treatment with 1,25D3 attenuates cytokine production following stimulation with G-HSA + IL-1beta and/or IL-17. MATERIAL AND METHODS: HGFs were incubated +/-G-HSA or normal human serum albumin (HSA), +/-IL-1beta and/or IL-17, +/-1,25D3. Cytokines were measured by ELISA. Neutralizing anti-RAGE was used to assess AGE-RAGE interaction. Endotoxin was measured using the ToxinSensorTM System. Data were expressed as mean +/- standard deviation and analyzed using a one-way analysis of variance (ANOVA) and Scheffe's F procedure for post hoc comparisons. RESULTS: G-HSA or IL-1beta, but not HSA, significantly stimulated IL-6 and IL-8 production. G-HSA or HSA when combined with IL-1beta or IL-1beta + IL-17 synergistically stimulated IL-6 and IL 8. Neutralizing anti-RAGE inhibited IL-6 and IL-8 produced by cells stimulated with IL-1beta + G-HSA but not (+HSA). Synergism caused by HSA did not appear to be mediated by endotoxin since its levels in G-HSA and HSA were not sufficient to stimulate fibroblasts. Vitamin D inhibited IL-6 and IL-8 production stimulated by G-HSA or HSA + IL-1beta or IL-1beta + IL-17. CONCLUSIONS: Results suggest that the "perioprotective" effects of vitamin D are related to its ability to regulate inflammatory cytokine production by HGFs following AGE-RAGE interaction. PMID- 30295317 TI - From Early Relationships to Preacademic Knowledge: A Sociocognitive Developmental Cascade to School Readiness. AB - This study aimed to test a four-wave sequential mediation model linking mother child attachment to children's school readiness through child executive functioning (EF) and prosociality in toddlerhood and the preschool years. Mother child attachment security was assessed when children (N = 255) were aged 15 months and 2 years, child EF at age 2, prosocial behavior at age 4, and finally cognitive school readiness in kindergarten (age 6). The results revealed three indirect pathways linking attachment to school readiness: one through EF only, one through prosocial behavior only, and a last pathway involving both EF and prosocial behavior serially. These findings suggest that secure attachment may equip children with both cognitive and social skills that are instrumental to their preparedness for school. PMID- 30295318 TI - New perspectives on binding in visual working memory. AB - How does visual working memory (WM) store the binding between different features of a visual object (like colour, orientation, and location), and does memorizing these bindings require additional resources beyond memorizing individual features? These questions have traditionally been addressed by comparing performance across different types of change detection task. More recently, experimental tasks such as analogue (cued) recall, combined with analysis methods including Bayesian hypothesis testing and formal model comparison, have shed new light on the properties of WM. A significant new perspective is that noise in neural representation limits the precision of recall, and several recent models incorporate this view to account for failures of binding in WM. We review the literature on feature binding with a focus on these new developments and discuss their implications for the interpretation of classical findings. PMID- 30295319 TI - A Family Focused Intervention Influences Hippocampal-Prefrontal Connectivity Through Gains in Self-Regulation. AB - The stressors associated with poverty increase the risks for externalizing psychopathology; however, specific patterns of neurobiology and higher self regulation may buffer against these effects. This study leveraged a randomized control trial, aimed at increasing self-regulation at ~11 years of age. As adults, these same individuals completed functional MRI scanning (Mage = 24.88 years; intervention n = 44; control n = 49). Functional connectivity between the hippocampus and ventromedial prefrontal cortex was examined in relation to the intervention, gains in self-regulation, and present-day externalizing symptoms. Increased connectivity between these brain areas was noted in the intervention group compared to controls. Furthermore, individual gains in self-regulation, instilled by the intervention, statistically explained this brain difference. These results begin to connect neurobiological and psychosocial markers of risk and resiliency. PMID- 30295320 TI - Rehabilitation Services Use of Older Adults According to Fall-Risk Screening Guidelines. AB - OBJECTIVES: To characterize rehabilitation services use of older adults according to fall-risk classification based on screening guidelines. DESIGN: Cross sectional analysis of 2015 National Health and Aging Trends Study. SETTING: Study participants' homes. PARTICIPANTS: National sample of 7,440 community-dwelling Medicare beneficiaries. MEASUREMENTS: In-person interviews and functional assessments. Based on Centers for Disease Control and Prevention Stopping Elderly Accidents, Deaths and Injuries criteria, participants were classified as low, moderate, or high fall risk. RESULTS: Twenty-three percent of older adults classified as moderate fall-risk (n = 2602) and 40.6% of those at high fall-risk (n = 940) reported rehabilitation services use in the past year. Among older adults who reported rehabilitation services in the past year (n = 1,505), treatment to address falls was reported by 2.8%, 12.6%, and 34.7% of those classified with low, moderate, and high fall-risk, respectively (p < 0.001). Older adults with high fall-risk who did not receive rehabilitation services had significantly better self-reported physical capacity (p = 0.02) but comparable physical performance (all p's > 0.05) relative to those who received rehabilitation. CONCLUSION: Older adults at high risk for falls were significantly more likely to report rehabilitation services use compared to those with low and moderate risk of falling. The findings also indicate that there is low adherence to national clinical recommendations for rehabilitation services use in older adults vulnerable to falls-related injury. Among the high fall-risk group, those who did not receive rehabilitation services had similarly low physical function as compared with those who received rehabilitation, indicating potential unmet need to address physical impairments related to fall-risk. PMID- 30295322 TI - Electroconvulsive therapy in unipolar depression treatment guidelines. PMID- 30295321 TI - Differential Effects of Salient Visual Events on Memory-Guided Attention in Adults and Children. AB - Both salient visual events and scene-based memories can influence attention, but it is unclear how they interact in children and adults. In Experiment 1, children (N = 27; ages 7-12) were faster to discriminate targets when they appeared at the same versus different location as they had previously learned or as a salient visual event. In contrast, adults (N = 30; ages 18-31) responded faster only when cued by visual events. While Experiment 2 confirmed that adults (N = 27) can use memories to orient attention, Experiment 3 showed that, even in the absence of visual events, the effects of memories on attention were larger in children (N = 27) versus adults (N = 28). These findings suggest that memories may be a robust source of influence on children's attention. PMID- 30295323 TI - Maternal Depressive Symptoms During the Pre- and Postnatal Periods and Infant Attention to Emotional Faces. AB - We examined how infants' attentional disengagement from happy, fearful, neutral, and phase-scrambled faces at 8 months, as assessed by eye tracking, is associated with trajectories of maternal depressive symptoms from early pregnancy to 6 months postpartum (decreasing n = 48, increasing n = 34, and consistently low symptom levels n = 280). The sample (mother-infant dyads belonging to a larger FinnBrain Birth Cohort Study) was collected between 5/2013-6/2016. The overall disengagement probability from faces to distractors was not related to maternal depressive symptoms, but fear bias was heightened in infants whose mothers reported decreasing or increasing depressive symptoms. Exacerbated attention to fearful faces in infants of mothers with depressive symptoms may be independent of the timing of the symptoms in the pre- and postnatal stages. PMID- 30295324 TI - The periodontal stem/progenitor cell inflammatory-regenerative cross talk: A new perspective. AB - Adult multipotent stem/progenitor cells, with remarkable regenerative potential, have been isolated from various components of the human periodontium. These multipotent stem/progenitor cells include the periodontal ligament stem/progenitor cells (PDLSCs), stem cells from the apical papilla (SCAP), the gingival mesenchymal stem/progenitor cells (G-MSCs), and the alveolar bone proper stem/progenitor cells (AB-MSCs). Whereas inflammation is regarded as the reason for tissue damage, it also remains a fundamental step of any early healing process. In performing their periodontal tissue regenerative/reparative activity, periodontal stem/progenitor cells interact with their surrounding inflammatory micro-environmental, through their expressed receptors, which could influence their fate and the outcome of any periodontal stem/progenitor cell-mediated reparative/regenerative activity. The present review discusses the current understanding about the interaction of periodontal stem/progenitor cells with their surrounding inflammatory micro-environment, elaborates on the inflammatory factors influencing their stemness, proliferation, migration/homing, differentiation, and immunomodulatory attributes, the possible underlying intracellular mechanisms, as well as their proposed relationship to the canonical and noncanonical Wnt pathways. PMID- 30295325 TI - A novel IkB kinase inhibitor attenuates ligature-induced periodontal disease in mice. AB - BACKGROUNDS AND OBJECTIVES: IMD-0354 is a novel I kappa-B kinase (IKK) inhibitor, which regulates inflammation. The purpose of this study was to examine the effect of the reagent on bone loss for ligature-induced periodontitis. MATERIAL AND METHODS: We ligated around the upper right second molars of 8-week-old C57BL/6J mice in the split-mouth model. The test mice were injected intraperitoneally with IMD-0354 before the placement of the ligature. The control mice were injected intraperitoneally with 0.5% carboxymethylcellulose (CMC) as vehicle before the placement of the ligature. To determine the optimum concentration of the reagent on ligature-induced periodontitis in the mice, we examined the effect of three types of concentration, which were 1, 5, and 10 mg/kg of IMD-0354, as a preliminary experiment. After we determined 10 mg/kg as the optimum concentration for the IMD group by micro-CT analysis, both the IMD and CMC groups (n = 15 each in total, including all the analyses) were subdivided into two small groups, respectively, for further analyses: I group (unligated side of IMD group), IL group (ligated side of IMD group), C group (unligated side of CMC group) and CL group (ligated side of CMC group). The mice in the IMD and CMC groups were treated with each reagent daily and sacrificed 8 days after the ligation. For assessment of bone resorption, we performed micro-CT and histological analyses. We also carried out real-time PCR to investigate proinflammatory and bone metabolic markers. RESULTS: There were significant differences for linear bone loss and volumetric parameter in the test (IMD) group compared to the control (CMC) group 8 days after ligation. In terms of the mRNA expression level of gingival tissue, the level of RANKL was significantly suppressed in the IMD group compared to the CMC group. IMD-0354 also tended to suppress the levels of interleukin-1 beta, tumor necrosis factor-alpha, and osteoprotegerin. For histological analysis, the relative numbers of TRAP-positive multinucleated cells decreased significantly in the IMD group compared to the CMC group. CONCLUSION: IMD-0354 regulated bone resorption by ligature-induced periodontitis, and it is suggested that the inhibition of IKK via down-regulation of NF kappa-B may provide periodontal patients with an effective approach to prevent or suppress the disease. PMID- 30295326 TI - A qualitative study of home visiting as a palliative care strategy to follow-up cancer patients by nurses in clinical setting in a developing country. AB - AIMS: The aims are to examine the effect of home visiting and resources for instituting the programme as a follow-up strategy in integration of palliative care in daily clinical practice by nurses caring for cancer patients in Nigeria, and on how it can be used to improve care for cancer patients. BACKGROUND: Home visiting by nurses has been used as a follow-up option in maternal and child health care globally. Most cancer patients default after diagnosis, home visiting offers potential as a strategy for follow-up of these patients too. METHODS: This was a qualitative study which employed a focus group discussion with nurse managers and interviews with cancer in-patients in two teaching hospitals in Nigeria. It utilised an interpretive paradigm to reach the best understanding of the problem. A total of 19 nurse managers who were directly involved with the care of cancer patients and 11 cancer patients participated in the study between July and September 2016. A qualitative content analysis was employed to analyse the data. FINDINGS: Nine major themes were identified in relation to perceived benefits of home visiting services and six in relation to needed resources in instituting the programme. Similar findings emerged from both the focus group discussions and the interviews with patients. Participants agreed that visiting cancer patients would ease many problems commonly encountered by patients following diagnosis of cancer, including psychological, financial, and emotional problems. Needed resources included hospital policies, adequate staff strength, staff commitment and funding. CONCLUSIONS: Viable home visiting requires palliative care teams to carry out the service and hospital policy to direct their activities. Putting this into practice will be in line with World Health Organisation (WHO) advocacy of integrated palliative care for chronic diseases. PMID- 30295327 TI - Sharing Positive Experiences Boosts Resilient Thinking: Everyday Benefits of Social Connection and Positive Emotion in a Community Sample. AB - The influence of shared enjoyment and positive affect (PA) on resilient thinking was examined in 191 middle-aged adults (40-65 years), participating in a study of resilience. Participants completed diaries assessing positive events, shared enjoyment, PA, and resilient cognitions (RC). Multilevel structural equation modeling was utilized to examine when and who engages in RC. Participants reported more RC on days they experienced more positive experiences. This relationship was explained by shared enjoyment and PA. Level-1 proportional reduction of variance (PRV) for shared enjoyment, PA, and RC was 9%, 10%, and 35%, respectively. Individuals reporting more positive experiences trended toward a more resilient mindset; PA accounted for this relationship. Shared enjoyment mediated the relationship between interpersonal events and PA. These findings suggest PA is integral to having a resilient mindset, and shared enjoyment is a potential mechanism that may influence PA. Level-2 PRV for shared enjoyment, PA, and RC was 22%, 21%, and 55%, respectively. RC were associated with less depression and anxiety; and greater well-being, vitality, and physical functioning at follow-up. PMID- 30295328 TI - Efficacy of sonically, ultrasonically and laser-activated irrigation in removing a biofilm-mimicking hydrogel from an isthmus model. AB - AIM: To evaluate the efficacy of sonically, ultrasonically and laser-activated irrigation (LAI) in removing a biofilm-mimicking hydrogel from the isthmus in a root canal model. METHODOLOGY: Transparent resin blocks containing two standardized root canals (apical diameter of 0.3 mm, 6% taper, 16 mm long, with a coronal reservoir) connected by an isthmus (0.15 mm wide, 2 mm high) were used as the test model. The isthmus was filled with a hydrogel-containing dentine debris. The canals were filled with irrigant, and the models were randomly assigned to the following activation groups (n = 20): EndoActivator (EA), Eddy, ultrasonically activated irrigation (UAI) with an Irrisafe 25 mm length, size 25 file and LAI with a 2940 nm Er:YAG-laser (20 Hz, 50 MUs, 20 mJ, PIPS tip at the canal entrance). All protocols were executed for 3 * 20 s. Needle irrigation (NI) with a 27G needle served as the control. Standardized images of the isthmus were taken before and after irrigation, and the amount of removed hydrogel was determined using image analysis software and compared across groups using Welch anova (P <= 0.05). RESULTS: Hydrogel removal was greatest in the LAI group (90.2%) and was significantly greater than that with UAI, EA and NI (P <= 0.014), but not significantly different from Eddy (P = 0.498). Hydrogel removal with Eddy (85.9%) was significantly greater than that with NI and EA (P < 0.05), but not significantly different from UAI (P = 0.07). There was no significant difference between the NI and EA groups (P = 1). CONCLUSIONS: Laser-activated irrigation and Eddy resulted in the greatest hydrogel removal and performed better than EA and UAI. The effect of LAI was also not dependent on deep intracanal tip placement. PMID- 30295329 TI - Comparing the effects of drawing and verbal recall techniques on children's memory accounts. AB - The present study compared the amount and accuracy of information Taiwanese children reported about a staged event in verbal-only and drawing-assisted interviews. We also tested further whether verbosity was a valid indicator of the accuracy of children's memory reports (Koriat & Goldsmith, , ) in a non-Western sample. Eighty-four first-grade elementary school children participated in a staged event involving a novel interactive puppet show followed by a drawing activity (drawing of the target event or the school), and were subsequently given a 10-minute memory interview. They were randomly assigned to a verbal cued-recall interview condition or a drawing-assisted interview condition. We did not find significant differences in the amount and accuracy of details reported between the two interview conditions. Our findings also revealed that the quantity of children's reports was positively related to the number of correct details reported, indicating that the children in our study did not demonstrate a quantity-accuracy tradeoff. PMID- 30295330 TI - Ascariasis as a model to study the helminth/allergy relationships. AB - Ascariasis is the most frequent soil transmitted helminthiasis and, as well as other helminth infections, is expected to influence the clinical presentation of allergic diseases such as asthma. Indeed, several clinical and experimental works have shown an important impact either increasing or suppressing symptoms, and the same effects have been detected on the underlying immune responses. In this review we analyze the work on this field performed in Colombia, a Latin American tropical country, including aspects such as the molecular genetics of the IgE response to Ascaris; the allergenic activity of Ascaris IgE-binding molecular components and the immunological and clinical influences of ascariasis on asthma. The analysis allows us to conclude that the impact of ascariasis on the inception and evolution of allergic diseases such as asthma deserves more investigation, but advances have been made during the last years. The concurrent parasite induced immunostimulatory and immunosuppressive effects during this helminthiasis do modify the natural history of asthma and some aspects of the practice of allergology in the tropics. Theoretically it can also influence the epidemiological trends of allergic diseases either by its absence or presence in different regions and countries.

AB - OBJECTIVE: To explore dental professionals' perceptions and experiences of providing oral health care for adults with mild to moderate mental health disorders (MHD) in Perth, Western Australia. METHODS: A grounded theory approach guided this research which comprised semi-structured interviews with oral health professionals working in private and/or public dental facilities attended by adults with MHD. An iterative analysis of transcripts identified emerging issues that were organized into categories under which key themes were noted, coded, compared, discussed, reviewed and revised independently by two researchers to ensure rigour. RESULTS: Sixteen interviews were conducted with six general dentists, three dental specialists, four oral health therapists (OHT) and three dental assistants. Barriers to providing oral health care for adults with MHD included limitations of the current model of care, often focused on treating advanced disease; limited inter-professional collaboration; an over-burdened public dental system and the financial constraints of private practice. Personal barriers included perceptions that people with MHD had limited capacity for self care and preventing oral disease. Factors that would enable oral health care included training and professional development for dental professionals to work effectively with people with MHD and a more flexible, inter-professional approach that involved prevention and inviting family to consultations about oral health in primary health care settings. CONCLUSIONS: Our study reveals structural barriers where services often appear to be inadequately prepared to meet the oral health needs of people with MHD. This suggests the need for strategies to review current models of care and encourage and support dental professionals to provide oral health care that is inclusive, inter-professional, focused on prevention and sensitive to the social context and lived experience of people with MHD.

AB - Cardiac anatomy can be challenging to grasp because of its complex three dimensional nature and remains one of the most challenging topics to teach. In light of some exciting technological advances in the field of virtual reality (VR), we sought to test the viability and the assess efficacy of this computer generated model for the purposes of teaching cardiac anatomy. Before learning cardiac anatomy, first-year undergraduate medical students participated in an anatomically correct VR simulation of the heart. Students were randomly distributed into control and variable groups. Each student completed a pre intervention quiz, consisting of 10 multiple choice questions with 5 conventional cardiac anatomy questions and 5 visual-spatial (VS) questions. The control group continued to independent study, whereas the variable group subjects were exposed to a 30-min immersive cardiac VR experience. At the end of the intervention, both the groups underwent a separate post-intervention 10-question quiz. Forty-two students participated in the cardiac VR experiment, separated into 14 control and 28 variable subjects. They scored 50.9% on average on the pre-intervention quiz (SD = 16.5) and 70.2% on the post-intervention quiz (SD = 18.7). Compared to the control group, the students exposed to VR scored 21.4% higher in conventional content (P = 0.004), 26.4% higher in VS content (P < 0.001), and 23.9% higher overall (P < 0.001). VR offers an anatomically correct and immersive VS environment that permits learner to interact three-dimensionally with the heart's anatomy. This study demonstrates the viability and the effectiveness of VR in teaching cardiac anatomy. Clin. Anat., 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30295334 TI - Characteristics of myeloproliferative neoplasms in patients exposed to ionizing radiation following the Chernobyl nuclear accident. AB - Myeloproliferative neoplasms (MPNs) driver mutations are usually found in JAK2, MPL, and CALR genes; however, 10%-15% of cases are triple negative (TN). A previous study showed lower rate of JAK2 V617F in primary myelofibrosis patients exposed to low doses of ionizing radiation (IR) from Chernobyl accident. To examine distinct driver mutations, we enrolled 281 Ukrainian IR-exposed and unexposed MPN patients. Genomic DNA was obtained from peripheral blood leukocytes. JAK2 V617F, MPL W515, types 1- and 2-like CALR mutations were identified by Sanger Sequencing and real time polymerase chain reaction. Chromosomal alterations were assessed by oligo-SNP microarray platform. Additional genetic variants were identified by whole exome and targeted sequencing. Statistical significance was evaluated by Fisher's exact test and Wilcoxon's rank sum test (R, version 3.4.2). IR-exposed MPN patients exhibited a different genetic profile vs unexposed: lower rate of JAK2 V617F (58.4% vs 75.4%, P = .0077), higher rate of type 1-like CALR mutation (12.2% vs 3.1%, P = .0056), higher rate of TN cases (27.8% vs 16.2%, P = .0366), higher rate of potentially pathogenic sequence variants (mean numbers: 4.8 vs 3.1, P = .0242). Furthermore, we identified several potential drivers specific to IR-exposed TN MPN patients: ATM p.S1691R with copy-neutral loss of heterozygosity at 11q; EZH2 p.D659G at 7q and SUZ12 p.V71 M at 17q with copy number loss. Thus, IR-exposed MPN patients represent a group with distinct genomic characteristics worthy of further study. PMID- 30295335 TI - Effect of crizanlizumab on pain crises in subgroups of patients with sickle cell disease: A SUSTAIN study analysis. AB - The cell adhesion molecule P-selectin plays a key role in the pathogenesis of a vaso-occlusive crisis (VOC) in patients with sickle cell disease (SCD). In the double-blind, placebo-controlled phase 2 SUSTAIN study, crizanlizumab (humanized, anti-P-selectin monoclonal antibody) 5 mg/kg significantly lowered the rate of VOC in patients with SCD by 45% vs placebo. In SUSTAIN, patients with SCD were randomized to crizanlizumab 2.5 mg/kg, crizanlizumab 5 mg/kg, or placebo intravenously 14 times over 52 weeks. The primary endpoint was the annual rate of VOC with crizanlizumab vs placebo. This post hoc descriptive analysis evaluated the proportion of patients who did not experience a VOC during the study in the following subgroups: VOCs in the year prior to study entry (2-4/5-10), SCD genotype (HbSS/non-HbSS), and concomitant hydroxyurea use (yes/no). More patients were VOC event-free in the crizanlizumab 5 mg/kg arm than in the placebo arm, including those with more frequent prior VOCs (ie, 5-10; 28.0% vs 4.2%), the HbSS genotype (31.9% vs 17.0%) and/or using concomitant hydroxyurea (33.3% vs 17.5%). Further analyses of secondary endpoints demonstrated that crizanlizumab treatment significantly increased time-to-first VOC vs placebo in these subgroups. The rates of treatment-emergent adverse events were similar between treatment arms across all subgroups. This post hoc analysis of SUSTAIN shows that in patients with a high number of prior VOCs, on concomitant hydroxyurea and/or with the HbSS genotype, crizanlizumab treatment increases the likelihood of patients being VOC event-free and delays time-to-first VOC.

PMID- 30295336 TI - High NEK2 confers to poor prognosis and contributes to cisplatin-based chemotherapy resistance in nasopharyngeal carcinoma. AB - Nasopharyngeal carcinoma (NPC) is a common malignant tumor in southern China and Southeast Asia, but the molecular mechanism of its pathogenesis is poorly understood. Our previous work demonstrated that NEK2 is overexpressed in multiple cancers. However, how NEK2 involves in NPC development remains to be elucidated. In this study, we firstly identified NEK2, located at +1q32-q33, a late event in NPC pathogenesis, overexpressed in the stage III-IV and paired sequential recurrent patients with NPC by immunohistochemistry. Furthermore, Kaplan-Meier analysis indicated high NEK2 conferred an inferior overall survival in NPC. In addition, cisplatin experiments with cell counting kit-8, colony formation, and a xenograft mice model of NPC demonstrated that NEK2 contributed to proliferation and cisplatin resistance in vitro and in vivo. On the contrary, downregulation of NEK2 by short hairpin RNA inhibited NPC cell growth and increased the sensitivity of cisplatin treatment in vitro. Thus, increased expression of NEK2 protein could not be predicted for poor survival but used as a novel biomarker for recurrence of NPC. Targeting NEK2 has the potential to eradicate the cisplatin-based chemotherapy resistant NPC cells. PMID- 30295338 TI - Fingolimod enhances the efficacy of delayed alteplase administration in acute ischemic stroke by promoting anterograde reperfusion and retrograde collateral flow. AB - OBJECTIVE: The present study was undertaken to determine the efficacy of coadministration of fingolimod with alteplase in acute ischemic stroke patients in a delayed time window. METHODS: This was a prospective, randomized, open label, blinded endpoint clinical trial, enrolling patients with internal carotid artery or middle cerebral artery proximal occlusion within 4.5 to 6 hours from symptom onset. Patients were randomly assigned to receive alteplase alone or alteplase with fingolimod. All patients underwent pretreatment and 24-hour noncontrast computed tomography (CT)/perfusion CT/CT angiography. The coprimary endpoints were the decrease of National Institutes of Health Stroke Scale scores over 24 hours and the favorable shift of modified Rankin Scale score (mRS) distribution at day 90. Exploratory outcomes included vessel recanalization, anterograde reperfusion, and retrograde reperfusion of collateral flow. RESULTS: Each treatment group included 23 patients. Compared with alteplase alone, patients receiving fingolimod plus alteplase exhibited better early clinical improvement at 24 hours and a favorable shift of mRS distribution at day 90. In addition, patients who received fingolimod and alteplase exhibited a greater reduction in the perfusion lesion accompanied by suppressed infarct growth by 24 hours. Fingolimod in conjunction with alteplase significantly improved anterograde reperfusion of downstream territory and prevented the failure of retrograde reperfusion from collateral circulation. INTERPRETATION: Fingolimod may enhance the efficacy of alteplase administration in the 4.5- to 6-hour time window in patients with a proximal cerebral arterial occlusion and salvageable penumbral tissue by promoting both anterograde reperfusion and retrograde collateral flow. These findings are instructive for the design of future trials of recanalization therapies in extended time windows. Ann Neurol 2018;84:725-736. PMID- 30295340 TI - Effect of low androgen levels on the sulphur dioxide signalling pathway in rat penile corpus cavernosum. AB - The aim of this study was to investigate the relationship between sulphur dioxide (SO2 ) signalling pathway and the changes in erectile function under low androgen levels. Thirty-six healthy male Sprague Dawley (SD) rats aged eight weeks were randomly divided into androgen replacement group, castration group and sham group. Rats in the androgen replacement group were subcutaneously injected with testosterone propionate at 3 mg/kg every other day postcastration. The maximum intracavernous pressure/mean arterial pressure (ICPmax /MAP) and the relative content of SO2 in the penile corpus cavernosum were measured. The mRNA and protein expressions of aspartate aminotransferase (AAT1 and AAT2), cysteine oxidase (CDO), endothelial nitric oxide synthase (eNOS) and phosphorylation of endothelial nitric oxide synthase (P-eNOS) were detected. ICPmax /MAP, P eNOS/eNOS and the level of SO2 decreased significantly in the castration group compared to the other groups (p < 0.05). The expressions of mRNA and protein decreased significantly in the castration group compared to the androgen replacement group and the sham group (p < 0.05), while there was no significant difference between the androgen replacement group and sham group. Low androgen levels can inhibit erectile function by downregulating the SO2 signalling pathway. PMID- 30295341 TI - The impact of China's latest population policy changes on maternity insurance-a case study in Jiangsu Province. AB - This study aims to examine the impact of China's population policy changes on social insurance. Nearly 4 decades ago, China ushered in the 1-child policy as a family planning policy to control the adverse effect of high population growth. The current maternity insurance system in China is designed to fit the operations of the 1-child policy. However, the implementation of the comprehensive 2-child policy can pose a challenge to the sustainability of the current maternity insurance scheme hence the call for reform. The study empanels a novel and comprehensive system dynamic model that incorporates all the related factors that influence the income and expenditure of maternity insurance in the Jiangsu Province. Data are mainly derived from the historical data of the Statistical Yearbook of Jiangsu Province and the National Bureau of Statistics of China. These are used to construct and simulate a system dynamic model to determine a sustainable contribution rate for maternity insurance. In conclusion, if the rate of contribution of the current maternity insurance policy is not increased, the burden of implementing the comprehensive 2-child policy will exacerbate the current deficit balance of the maternity insurance fund. The existing maternity insurance benefits thus cannot be maintained, and women's health will be threatened. In the short term, the study proposes an increase in the rate of premium payment to prolong the life of the maternity insurance. In the long term, there is a need to improve the level of coordination and expand the coverage of maternity insurance. PMID- 30295342 TI - Evaluation of chemical and morphological changes in radicular dentin after different final surface treatments. AB - The aim of this study was to evaluate the chemical and morphological effects of different lasers as a final surface treatment for endodontic therapy through energy dispersive X-ray spectroscopy (EDS) and scanning electron microscopy (SEM) respectively. Twenty-five maxillary canines were selected and instrumented with K3 system. Roots were randomly distributed into five groups (n = 5) according to the surface treatment: GI (distilled water), GII (NaOCl + EDTA), GIII (NaOCl + EDTA + 980 nm diode laser), GIV (NaOCl + EDTA+ 1,064 nm Nd:YAG laser), and GV (NaOCl + EDTA+ 2,780 nm Er, Cr:YSGG laser). Lasers were applied for 20 s and samples were bisected, exposing the treated surface and then subjected to elements quantification by EDS and morphological evaluation by scanning electron microscope (SEM). EDS data were submitted to ANOVA-two way, and SEM scores were submitted to two-way Kruskal-Wallis and Dunn's tests. The EDS analysis showed no difference for the chemical elements and Ca/P ratio between groups (p > .05). Statistical analysis showed more intense results for GV and less intense results for GI (p < .05). The GIII showed an amorphous organic matrix surface, while GV provided greater removal of intertubular dentin forming craters, and GIV promoted dentin fusion. The EDS method used in this study was not able to verify any chemical changes in root canal dentin; Nd:YAG, Er, Cr:YSGG, and 980 nm diode laser were capable of modifying the dentin morphology, correlating characteristics features for each one, which are essential clinical knowledge to establish the correct indication for each case. RESEARCH HIGHLIGHTS: EDS was not able to verify any chemical changes in root canal dentin after 980 nm diode, Nd:YAG and Er;Cr:YSGG laser treatments Nd:YAG, Er, Cr:YSGG, and 980 nm diode laser modified dentin morphology, correlating characteristics features for each one.

AB - BACKGROUND: Knowledge of tissue properties of the abdominal aorta can improve understanding of vascular disease and guide interventional approaches. Existing MRI methods to quantify aortic wall displacement and strain are unable to discern circumferential heterogeneity. PURPOSE: To assess regional variation in abdominal aortic wall displacement and strain as a function of circumferential position using spiral cine displacement encoding with stimulated echoes (DENSE). STUDY TYPE: Prospective. POPULATION: Cardiovascular disease-free men (n = 8) and women (n = 9) ages 30-42. SEQUENCES: Prospective electrocardiogram (ECG)-gated and navigator echo-gated spiral, cine 2D DENSE and retrospective ECG-gated phase contrast MR (PCMR) sequences at 3T. ASSESSMENT: In-plane displacement values of the aortic wall acquired with DENSE were used to determine radial and circumferential aortic wall motion. A quadrilateral-based 2D strain calculation method was implemented to determine strain from the displacement field. Peak displacement and its radial and circumferential contributions as well as peak circumferential strain were compared among eight circumferential wall segments. Distensibility was calculated using PCMR and compared with homogenized circumferential strain. STATISTICAL TESTS: To account for repeated measurements in volunteers, linear mixed models for mean sector values were created for displacement magnitude, circumferential displacement, radial displacement, and circumferential strain. Comparisons were made between sectors. Calculated distensibility and homogenized circumferential strain were compared using Bland Altman analysis. Statistical significance was defined as P < 0.05. RESULTS: Displacement was highest in the anterior wall (1.5 +/- 0.7 mm) and was primarily in the radial as compared with circumferential direction (1.04 +/- 0.05 mm vs. 0.81 +/- 0.42 mm). Circumferential strain was highest in the lateral walls (left 0.16 +/- 0.05 and right 0.21 +/- 0.12) with homogenized circumferential strain of 0.14 +/- 0.05. DATA CONCLUSION: DENSE imaging in the abdominal aortic wall demonstrated that the anterior aortic wall exhibits the greatest displacement, while the lateral wall experiences the largest circumferential strain.

AB - More than a decade after the introduction of compressed sensing (CS) in MRI, researchers are still working on ways to translate it into different research and clinical applications. The greatest advantage of CS in MRI is the reduced amount of k-space data needed to reconstruct images, which can be exploited to reduce scan time or to improve spatial resolution and volumetric coverage. Efficient data acquisition using CS is extremely important for compositional mapping of the musculoskeletal system in general and knee cartilage mapping techniques in particular. High-resolution quantitative information about tissue biochemical composition could be obtained in just a few minutes using CS MRI. However, in order to make this goal a reality, some issues still need to be addressed. In this article we review the current state of the art of CS methods for rapid compositional mapping of knee cartilage. Specifically, data acquisition strategies, image reconstruction algorithms, and data fitting models are discussed. Different CS studies for T2 and T1rho mapping of knee cartilage are reviewed, with illustrative results. Future directions, opportunities, and challenges of rapid compositional mapping techniques are also discussed. Level of Evidence: 4 Technical Efficacy: Stage 6 J. Magn. Reson.

AB - The phasor approach to FLIM (Fluorescence Lifetime Imaging Microscopy) is becoming popular due to the powerful fit free analysis and the visualization of the decay at each point in images of cells and tissues. However, although several implementation of the method are offered by manufactures of FLIM accessories for microscopes, the details of the conversion of the decay to phasors at each point in an image requires some consideration. Here, we show that if the decay is not properly acquired, the apparently simple phasor transformation can provide incorrect phasor plots and the results may be misinterpreted. In particular, we show the disagreement in experimental data acquired on the same samples using the two cards (FLIMbox, frequency domain and Becker & Hickl BH 830, time domain) and the effect produced by using the BH 830 card with different settings. This difference in data acquisition translates to the assignment of phasor components calculated using different acquisition parameters. This effect is already present in the original data that are not acquired with the proper parameters for the phasor conversion. We also show that the difference in the resolution of components already exists in the data acquired in the time domain when used with settings that do not allow acquisition of the fluorescence decay on a sufficient large time scale. RESEARCH HIGHLIGHTS: This paper is intended to made researchers aware of some simple requirements for the conversion of time-domain data (typically TCSPC) to phasors. The use of phasors for FLIM analysis has seen a surge of popularity. Since the phasor approach is a fit free method and has a powerful visualization of the data, it appears very simple to use. This paper shows that when the original data in the time domain is not acquired with the proper time range to cover the lifetimes in a sample, the conversion to phasors can produce very erroneous results. These results are appearing more frequently in the literature since many of the manufacturers of FLIM accessories for microscopes are now offering the phasor analysis in their software. Here, we show that the phasor transformation per se cannot correct for the problems with data acquisition and that one is misled to think that the "phasor approach" is a universal fix for the lack of the proper time range for data acquisition. PMID- 30295348 TI - Abnormal Hippocampal Subfields May Be Potential Predictors of Worse Early Response to Antidepressant Treatment in Drug-Naive Patients With Major Depressive Disorder. AB - BACKGROUND: Previous studies had proved that hippocampal volume has predictive value for antidepressant response in patients with major depressive disorder (MDD). However, the exact subregion of the hippocampus relevant to the predictive role of antidepressants response is not known. PURPOSE: To explore which hippocampal subfield volumes might predict an early response to first-time use of antidepressants in drug-naive MDD patients. STUDY TYPE: Prospective. POPULATION: Thirty-eight drug-naive MDD patients (mean illness duration = 1.6 years) and 55 healthy control subjects (HCS). FIELD STRENGTH/SEQUENCE: 3.0T MRI, T1 -weighted, 3D, SPGR sequence. ASSESSMENT: The hippocampal subfields and total intracranial volume were measured with FreeSurfer. The response to antidepressants was evaluated by the reduction rate of the Hamilton Rating Scale for Depression score (RRS) after a 6-week routine clinical antidepressant treatment. STATISTICAL TESTS: The relationship between hippocampal subfield volumes and RRS was explored using partial correlation analysis. Volume differences among early responding patients (ERP), nonresponding patients (NRP), and HCS were examined by multivariate analysis of covariance. Receiver operating characteristic (ROC) curve analysis was used to evaluate the sensitivity and specificity of volumes as predictors. RESULTS: NRP had significantly larger volumes than both ERP and HCS in bilateral subiculum, cornu ammonis (CA) 1 and left CA2/3, CA4/dentate gyrus (DG) (all P < 0.01, false discovery rate corrected). Significant negative correlations were found between the RRS and volumes of left subiculum (P = 0.004), CA2/3 (P = 0.008), and CA4/DG (P = 0.004) in the whole MDD group. ROC analysis demonstrated that the left subiculum exhibited the highest accuracy for differentiating NRP from ERP, with a sensitivity of 76.9% and specificity of 80%. DATA CONCLUSION: These findings propose that volumes of certain hippocampal subfields may be associated with antidepressant treatment and this has potential use in clinical applications for treatment selection in patients with MDD at an early stage.

AB - Herein, the chemical synthesis and binding analysis of functionalizable rigid and flexible core trivalent sialosides bearing oligoethylene glycol (OEG) spacers interacting with spike proteins of influenza A virus (IAV) X31 is described. Although the flexible Tris-based trivalent sialosides achieved micromolar binding constants, a trivalent binder based on a rigid adamantane core dominated flexible tripodal compounds with micromolar binding and hemagglutination inhibition constants. Simulation studies indicated increased conformational penalties for long OEG spacers. Using a systematic approach with molecular modeling and simulations as well as biophysical analysis, these findings emphasize on the importance of the scaffold rigidity and the challenges associated with the spacer length optimization. PMID- 30295349 TI - Spatial object recognition memory formation under acute stress. AB - Stress is known to have a critical impact on memory processes. In the present work, we focus on the effects of an acute stress event closely associated to an unrelated learning task. Here we show that acute stress (elevated platform session, EP) experienced one hour after a weak spatial object recognition training (SOR), which only induces a short-term memory (STM), promoted the formation of SOR-long term memory (SOR-LTM) in rats. The effect induced by stress was dependent on the activation of glucocorticoid- and mineralocorticoid receptors, brain-derived neurotrophic factor (BDNF) and protein synthesis in the dorsal hippocampus. In contrast, EP after a strong SOR impaired SOR-LTM probably by interfering with the use of necessary resources. Moreover, we show that the EP session before training induced anterograde interference, which it was not reversed by a subsequent exposure to an open field. Our findings provide novel insights into the impact of stress on LTM formation in rodents and they are discussed under the behavioral analogue of the synaptic tagging and capture hypothesis.

AB - While clusterin is reportedly involved in Alzheimer's disease (AD) pathogenesis, how clusterin interacts with amyloid-beta (Abeta) to cause Abeta neurotoxicity remains unclear in vivo. Using 5*FAD transgenic mice, which develop robust AD pathology and memory deficits when very young, we detected interactions between clusterin and Abeta in the mouse brains. The two proteins were concurrently upregulated and bound or colocalized with each other in the same complexes or in amyloid plaques. Neuropathology and cognitive performance were assessed in the progeny of clusterin-null mice crossed with 5*FAD mice, yielding clu-/- ;5*FAD and clu+/+ ;5*FAD. We found far less of the various pools of Abeta proteins, most strikingly soluble Abeta oligomers and amyloid plaques in clu-/- ;5*FAD mice at 5 months of age. At that age, those mice also had higher levels of neuronal and synaptic proteins and better motor coordination, spatial learning and memory than age-matched clu+/+ ;5*FAD mice. However, at 10 months of age, these differences disappeared, with Abeta and plaque deposition, neuronal and synaptic proteins and impairment of behavioral and cognitive performance similar in both groups. These findings demonstrate that clusterin is necessarily involved in early stages of AD pathogenesis by enhancing toxic Abeta pools to cause Abeta-directed neurodegeneration and behavioral and cognitive impairments, but not in late stage. PMID- 30295347 TI - KCTD7 deficiency defines a distinct neurodegenerative disorder with a conserved autophagy-lysosome defect. AB - OBJECTIVE: Several small case series identified KCTD7 mutations in patients with a rare autosomal recessive disorder designated progressive myoclonic epilepsy (EPM3) and neuronal ceroid lipofuscinosis (CLN14). Despite the name KCTD (potassium channel tetramerization domain), KCTD protein family members lack predicted channel domains. We sought to translate insight gained from yeast studies to uncover disease mechanisms associated with deficiencies in KCTD7 of unknown function. METHODS: Novel KCTD7 variants in new and published patients were assessed for disease causality using genetic analyses, cell-based functional assays of patient fibroblasts and knockout yeast, and electron microscopy of patient samples. RESULTS: Patients with KCTD7 mutations can exhibit movement disorders or developmental regression before seizure onset, and are distinguished from similar disorders by an earlier age of onset. Although most published KCTD7 patient variants were excluded from a genome sequence database of normal human variations, most newly identified patient variants are present in this database, potentially challenging disease causality. However, genetic analysis and impaired biochemical interactions with cullin 3 support a causal role for patient KCTD7 variants, suggesting deleterious alleles of KCTD7 and other rare disease variants may be underestimated. Both patient-derived fibroblasts and yeast lacking Whi2 with sequence similarity to KCTD7 have impaired autophagy consistent with brain pathology. INTERPRETATION: Biallelic KCTD7 mutations define a neurodegenerative disorder with lipofuscin and lipid droplet accumulation but without defining features of neuronal ceroid lipofuscinosis or lysosomal storage disorders. KCTD7 deficiency appears to cause an underlying autophagy-lysosome defect conserved in yeast, thereby assigning a biological role for KCTD7. Ann Neurol 2018;84:774-788. PMID- 30295352 TI - Rho and Rac, but not ROCK, are required for secretion of human and mouse eosinophil-associated RNases. AB - BACKGROUND: Eosinophil-associated RNases (EARs) are stored preformed in eosinophil cytoplasmic secretory granules and have a key role in eosinophil effector functions in host defence and inflammatory disorders. However, the secretion mechanisms of EARs are poorly understood. OBJECTIVE: Our study aimed to understand the involvement of cytoskeleton machinery in EAR secretion. METHODS: Fresh human and mouse eosinophils were stimulated with CCL11, and the secretion of enzymatically active EARs was detected using an RNase activity assay. The involvement of cytoskeletal elements or microtubules was probed using specific inhibitors. RESULTS: We found that dynamic polymerization of microtubules and cytoskeletal elements, such as Rho and Rac, is required for chemokine-mediated EAR secretion from human and mouse eosinophils. However, inhibition of ROCK (Rho associated protein kinase) increased EAR secretion in human and mouse eosinophils even in the absence of chemokine stimulation, suggesting ROCK negatively regulates EAR secretion. CONCLUSIONS: Collectively, these data suggest a cytoskeleton-dependent mechanism of EAR secretion from eosinophils, findings that are pertinent to host defence, allergy and other eosinophil-associated diseases.

AB - Although video polysomnography (vPSG) is not routinely recommended for the evaluation of typical cases of non-rapid eye movement (NREM) parasomnias, it can aid diagnosis of unusual cases, other sleep disorders and complicated cases with REM behaviour disorder (RBD), and in differentiating parasomnias from epilepsy. In this study, we aimed to assess vPSG findings in consecutive patients with a clinical diagnosis of NREM-parasomnia covering the whole phenotypic spectrum. Five hundred and twelve patients with a final diagnosis of NREM parasomnia who had undergone vPSG were retrospectively identified. vPSGs were analysed for features of NREM parasomnia and for the presence of other sleep disorders. Two hundred and six (40.0%) patients were clinically diagnosed with sleepwalking, 72 (14.1%) with sleep terrors, 39 (7.6%) with confusional arousals, 15 (2.9%) with sexsomnia, seven (1.4%) with sleep-related eating disorder, 122 (23.8%) with mixed phenotype, and 51 (10.0%) with parasomnia overlap disorder (POD). The vPSG supported the diagnosis of NREM parasomnia in 64.4% of the patients and of POD in 98%. In 28.9% of the patients, obstructive sleep apnea (OSA) or/and periodic limb movements during sleep (PLMS) were identified, most commonly in older, male, sleepy and obese patients. vPSG has a high diagnostic yield in patients with NREM parasomnia and should be routinely performed when there is diagnostic doubt, or in patients where there is a suspicion of OSA and PLMS. PMID- 30295354 TI - Enamel sample preparation for AFM: Influence on roughness and morphology. AB - Human dental enamel is organized by prisms that are structured between 3 and 6 um in diameter. Determining the relationships between different treatments on the surface of enamel using ultrastructural analysis is the purpose of many in vitro experiments. Different sample pretreatments have been reported in the literature. Grinding and polishing are common procedures for enamel preparation. They provide a flat and standardized surface, which is imperative for the use of some techniques such as ATR-FTIR. However, for morphological analysis, SEM and AFM represent easier methods to measure and reduce the biological sample variation. Therefore, the objective of this study was to establish how different forms of enamel preparation can influence the advent of artifacts during ultrastructural observation, especially by AFM analysis. Four groups (n = 10) were tested: (a) without preparation; (b) polishing with a diamond paste; (c) grinding with decreasing granulations of silicon carbide papers; (d) grinding with polishing. Images were obtained using the Peak-Force Tapping mode. After the first images were obtained, all fragments were acid etched with 37% phosphoric acid for 30 seconds, rinsed for 60 seconds, and dried intensively. Upon grinding and polishing, the exposure of the inner enamel surfaces provided a less mineralized layer that was marked by scratches and a higher susceptibility to treatments. Moreover, using native enamel provided more valuable information on the surface and the roughness changes for clinical applications. In addition, phosphoric acid is an option for observing the prismatic arrangement after grinding and/or polishing changes the morphology. RESEARCH HIGHLIGHTS: The use of native enamel samples to investigate the effects of different treatments on surface should be preferred in research, when the technique allows it. PMID- 30295355 TI - Quantification of crystallinity using zero-loss filtered electron diffraction. AB - : The quantity of the crystalline phases present in a nanomaterial is an important parameter that governs the correlation between its properties and microstructure. However, quantification of crystallinity in nanoscale-level applications by conventional methods (Raman spectroscopy and X-ray diffraction) is difficult because of the spatial limitations of sampling. Therefore, we propose a technique that involves using energy-filtered electron diffraction in transmission electron microscopy which offers improved spatial resolution. The degree of crystallinity (DOC) was calculated by separating the crystalline and amorphous intensities from the total intensity histogram acquired by the azimuthal averaging of the zero-loss filtered signals from electron diffraction. In order to validate the method, it was demonstrated that the DOC calculated by zero-loss filtered electron diffraction was consistent with the DOC measured by the area ratio using an amorphous silicon on crystalline silicon standard sample. In addition, the results obtained from zero-loss filtered and conventional electron diffractions were compared. The zero-loss filtered electron diffraction successfully provided the reliable results of the crystallinity quantification. In contrast, the DOC measured using conventional electron diffraction yielded extremely variable results. Therefore, our results provide a crystallinity quantification technique that can extract quantitative information about crystallinity of nanoscale devices by using zero-loss filtered electron diffraction with better reliability than conventional electron diffraction. RESEARCH HIGHLIGHTS: The degree of crystallinity can be measured by separating the crystalline and amorphous intensities from the total intensity histogram acquired by the azimuthal averaging of the zero-loss filtered signals from selected area electron diffraction.

AB - Crystal engineering of three-component crystals with guest-dependent photoluminescence switching, including (i) crystallization-induced emission enhancement, (ii) intermolecular charge-transfer emission, and (iii) room temperature phosphorescence under ultraviolet irradiation, was demonstrated. This strategy was based on the confinement of aromatic guests in a supramolecular host (denoted as EBPDI-TPFB) composed of 5,5'-(ethyne-1,2-diyl)bis(2-pyridin-3-yl isoindoline-1,3-dione (EBPDI) with two tris(pentafluorophenyl)borane (TPFB) molecules linked by B-N dative bonds that acted as Lewis pairs. The single crystal X-ray structures of complexes with eight different guests were collected, revealing that the size and/or shape of the supramolecular host EBPDI-TPFB was modulated by the included guest molecules. The excellent guest inclusion ability of EBPDI-TPFB allowed systematic photoluminescence regulation of the complexes, which exhibited multicolor emissions in the crystalline state. Photoluminescence switching characteristics of the complexes were observed upon removing the guests or mechanical grinding of the crystals. These results indicated that using the host-guest chemistry of multicomponent crystals not only facilitates crystallization, but also can reveal hidden optical functions by combining molecules of interest, which should contribute to the fields of physical chemistry and materials science. PMID- 30295357 TI - Dilutional coagulopathy in pediatric scoliosis surgery: A single center report. AB - BACKGROUND: Children undergoing posterior spinal fusion experience high blood loss often necessitating transfusion. An appropriately activated coagulation system provides hemostasis during surgery, but pathologic dysregulation can cause progressive bleeding and increased transfusions. Despite receiving antifibrinolytics for clot stabilization, many patients still require transfusions. AIMS: We sought to examine the association of dilutional coagulopathy with blood loss and blood transfusion in posterior spinal fusion for pediatric scoliosis patients. METHODS: A retrospective, single institution study of children undergoing posterior spinal fusion >6 levels with a standardized, prospective anesthetic protocol utilizing antifibrinolytics. Blood loss was evaluated using a hematocrit-based calculation. To evaluate transfusions, a normalized Blood Product Transfusion calculation was developed. Factors associated with blood loss and blood transfusions were determined by univariate analysis and multivariate regression modeling with multicollinearity and mediation analysis. RESULTS: Patients received 73.7 mL/kg (standard deviation +/ 30.8) of fluid poor in coagulation factors. Estimated blood loss was 42.6 mL/kg (standard deviation +/-18.0). There was a significant association between estimated blood loss and total fluids delivered (Spearman's rho = 0.51, 95% confidence interval 0.33-0.65, P < 0.001). Factors significantly associated with normalized Blood Product Transfusion in this cohort included age, weight, scoliosis type, levels fused, total osteotomies, pelvic fixation, total fluid, maximum prothrombin time, and minimum fibrinogen. Regression modeling showed the best combination of variables for modeling normalized Blood Product Transfusion included patient weight, number of levels fused, total fluid administered, and maximum prothrombin time. CONCLUSION: Blood product transfusion remains a frustrating problem in pediatric scoliosis. Identifying and controlling dilutional coagulopathy in these patients may reduce blood loss and the need for blood transfusion. PMID- 30295358 TI - Electrical Stimulation of the Anterior Thalamus for Epilepsy: Clinical Outcome and Analysis of Efficient Target. AB - OBJECTIVE: Deep brain stimulation (DBS) of the anterior thalamic complex (ANT) is an adjunctive therapy for pharmacoresistant epilepsy. To define the most efficient target in DBS for epilepsy, we investigate clinical data, position of leads, usability of atlas data compared to electric field modeling based on programming parameters. METHODS: Data from ten consecutive patients who underwent ANT-DBS were analyzed. The mammillothalamic tract (MTT), an internal landmark for direct stereotactic targeting, was segmented from MRI. Centers of stimulation were determined and their positions relative to ventricles and the MTT were analyzed. Two 3D thalamus atlases were transformed to segmented patient's thalami and proportions of activated nuclei were calculated. RESULTS: Our data indicate higher response rates with a center of stimulation 5 mm lateral to the wall of the third ventricle (R2 for reduction of focal seizure frequency and distance to the wall of the third ventricle = 0.48, p = 0.026). For reduction of focal seizures, a strong positive correlation with the dorsal distance to the midcommissural plane was found (R2 = 0.66, p = 0.004). In one 3D atlas, stimulation of internal medullary lamina (IML) correlated strongly positive with response rates, which, however, did not reach statistical significance (R2 = 0.69, p = 0.17 for tonic-clonic seizures). All electrical fields covered the diameter of the MTT. The position of the MTT in the thalamus was highly variable (range: x-coordinate 4.0 to 7.3 mm, y-coordinate -1.3 to 5.1 mm in AC-PC space). CONCLUSIONS: The distance of the active contact to the lateral wall of the third ventricle, MTT and the ventrodorsal distance to midcommissural plane appear to be relevant for optimal target planning. For reduction of focal seizure frequency, we found best response rates with a center of stimulation 5 mm lateral to the wall of the third ventricle, and a lead tip 10 mm dorsal of the midcommissural plane. PMID- 30295359 TI - Anesthesia in children with osteogenesis imperfecta: Retrospective chart review of 83 patients and 205 anesthetics over 7 years. AB - BACKGROUND: Osteogenesis imperfecta is the collective term for a heterogeneous group of connective tissue syndromes characterized by bone fragility with multisystem involvement and perioperative implications. AIMS: Literature review of anesthetic management of patients with osteogenesis imperfecta revealed a paucity of data on the incidence of perioperative challenges. We sought to determine the rates of these challenges in our study cohort. METHODS: Data were collected in a specialty orthopedic hospital from 2008 to 2015 for 83 osteogenesis imperfecta patients undergoing 205 surgeries: 203 orthopedic surgeries and 2 mid-face reconstructive surgeries. Airway management, intravenous access, surgical blood loss, use of peripheral nerve blockade and/or neuraxial techniques, presence of perioperative fracture, and peak intraoperative temperature were evaluated and analyzed. RESULTS: Difficult airway was encountered in 3/205 (1.5%) cases and perioperative fracture in 2/205 (1%) cases. Neuraxial anesthesia was attempted in 64/205 cases with an 87.5% success rate. All peripheral nerve block attempts (33/205 cases) were successful. Difficult intravenous catheter placement was noted in 8/205 (4%) cases. Estimated blood loss >10% of estimated blood volume was considered significant, and occurred in 35/205 (17%) cases. Significant blood loss occurred more often in severe osteogenesis imperfecta types: 18/76 (23.7%) in Type III and 11/65 (16.9%) in Type IV, whereas only 4/47 (8.5%) occurred in mild Type I. In our 205 case cohort, osteogenesis imperfecta Type III had 5.6 times the odds [(95% CI = 1.8 17.2) P = 0.003] of having an anesthetic complication as compared to osteogenesis imperfecta Type I. CONCLUSION: Patients with osteogenesis imperfecta undergo frequent anesthetic exposures, but anesthetic challenges in our series were uncommon. Odds of challenges are greater in severe osteogenesis imperfecta Type III, with significant blood loss and difficulty placing intravenous catheters more likely encountered in the more severe types.

PMID- 30295361 TI - A simplified method of preparation of mammalian intestine samples for scanning electron microscopy. AB - Due to strong tissue hydration and complex architecture of the mucous membrane, appropriate preparation of inhomogeneous gastrointestinal tissues, especially from the intestine, for scanning electron microscopy is still a challenge and requires constant improvement of preparation techniques. In this article, we describe a simplified method of preparation of small intestinal mucosa tissues for observations in a scanning electron microscope. We emphasized the most important points in the preparation process that, when ignored, may result in formation of numerous artifacts and the inability to analyze the samples reliably. The developed technique facilitates proper animal tissue sampling in the field conditions, reducing the time of tissue collection and sample preparation as well as the total process costs. The fixative of choice, that is, buffered formalin, fixes, and stiffens the processed tissues properly, which is especially important in preservation of long, highly hydrated intestinal villi without shrinkage artifacts. The method described has been successfully used in comparative studies of the development of small intestines in mammals (pigs, mice, rats), reptiles, and birds (hens). PMID- 30295362 TI - Histomorphometry of ectopic mineralization using undecalcified frozen bone sections. AB - To investigate the correlation between mineral formation and enhanced expressions of some proteins using undecalcified frozen bone sections. Histological studies have revealed that some proteins, such as BMP2, BMPR1A, and Connexin 43, are expressed in and around sites of ectopic ossification. However, the relationship between the expressed proteins considered to be associated with the ossification and mineral formation in vivo is not clear. Ectonucleotide pyrophosphatase phosphodiesterase 1 (ENPP1)-mutant spinal hyperostotic TWY mice and ICR mice as controls were euthanized after calcein labeling, and undecalcified frozen sections were obtained from the middle thoracic spine. Intervertebral disc areas were examined histologically and by measuring calcein-labeled areas and areas showing immunoreactivity for BMP2, BMPR1A, and Connexin 43. Calcein-labeled areas, indicating mineralization in the ectopic mineralization sites, were significantly larger in the mutant mice than in controls. The expression of Connexin 43 was elevated in the annulus fibrosus. Increases in the calcein labeled areas was not correlated with increases in the areas showing immunoreactivity for Connexin 43 in the annulus fibrosus. There was no statistical correlation between enhanced immunohistochemical expression and elevated calcein-labeled areas. By applying the morphometrical analysis method using undecalcified frozen sections to ENPP1-mutant mice, quantitative evaluation of the mineralization and proteins expressed in the surrounding area in the same animal became possible. PMID- 30295363 TI - An electron microscopy three-dimensional characterization of titania nanotubes. AB - : To characterize complex, three-dimensional nanostructures, modern microscopy techniques are needed, such as electron tomography and focused ion beam (FIB) sectioning. The aim of this study was to apply these two techniques to characterize TiO2 nanotubes in terms of their size, shape, volume, porosity, geometric surface area, and specific surface area (SSA). For these experiments, titania nanotubes were fabricated by means of the electrochemical oxidation of titanium at a voltage of 20 V for 2 hr followed by heat treatment at 450 degrees C for 3 hr to change the amorphous structure into a crystalline anatase structure. The quantitative data obtained from the FIB and electron tomography reconstructions show a high similarity in porosity and some differences in SSA. These might be the result of differences in resolution between the two reconstruction techniques. RESEARCH HIGHLIGHTS: The resolution of electron tomography method is better than FIB sectioning that might influence on quantitative data like SSA. FIB sectioning allows to visualize 3D structure of much larger volume than electron tomography method. FIB sectioning and electron tomography are complementary techniques for characterizing nanostructured materials such as nanotube layers. PMID- 30295364 TI - Morphological evaluation of liposomal iron carriers. AB - Iron is one of the most important elements for human, because it plays an essential role in many metabolic processes. However, it is also recognized to be dangerous for its detrimental effect inside human cells, where, in the absence of homeostatic balance, it can induce free radicals formation. Moreover, an excessive accumulation of iron in tissues can produce iron overload, a condition incompatible with life. The use of liposomes as carriers can represent an interesting iron therapy to improve iron bioavailability and reduce its negative effects, in particular during pregnancy. In this study, a morphological analysis has been performed on commercial liposome vesicles at various drying times, both in saline solution and in distilled water. Furthermore, to highlight their possible interaction or internalization in cells, liposomes have been administered to human hemopoietic U937 cells. Ultrastructural analyses confirm that vesicle morphology and size are comparable with classical liposomal structures. Products are stable during specimen preparation and drying. Additionally, they have a good ability to penetrate into cells, interacting with cytoplasmic organelles, without inducing, at least apparently, any ultrastructural damage. PMID- 30295365 TI - Surface characteristics of a modified acidulated phosphate fluoride gel with nano hydroxyapatite coating applied on bovine enamel subjected to an erosive environment. AB - This study evaluated the antierosive effect applying a modified acidulated phosphate fluoride (APF) gel containing nano-hydroxyapatite (nHAp) on the enamel surface before erosion. After polishing, the exposed flat enamel surfaces (n = 7/group) from bovine incisors were treated with artificial saliva (S - negative control), orange juice (ERO), APF gel (positive control) and APF_nHAp gel. All samples were subjected to six cycles of demineralization (orange juice, pH ~ 3.5, 10 min) followed by remineralization (saliva, 37 degrees C, 1 hr). The enamel surface morphology, topography, and inorganic composition were analyzed using scanning electron microscopy, roughness testing, and micro energy-dispersive X ray fluorescence spectrometry, respectively. The mean (standard deviation) roughness values (Ra, MUm) were S, 0.13 (0.05); ERO, 0.25 (0.07); APF, 0.22 (0.08); and APF_nHAp, 0.17 (0.04). Ra values were significantly higher after ERO (p < .01) and APF (p < .05) treatments than after S. The enamel surface morphology was altered by the treatments, except for the S specimens. The mineral content of the enamel showed a clear trend with Ca and P reduction in the order of APF < S < APF_nHAp < ERO and APF < S < ERO < APF_nHAp, respectively. We can conclude that APF gel increased mineral concentration on the enamel. Moreover, the APF_nHAp material modified the composition and morphology of the enamel surface. PMID- 30295366 TI - Morphological evaluation of the liver in Wistar rats inoculated with Rhipicephalus sanguineus (Latreille, 1806) (Acari: Ixodidae) salivary gland extracts. AB - The Rhipicephalus sanguineus is considered a species of medical and veterinary importance. The feeding process of these animals occurs due to the combined action of their mouthparts and the saliva produced by the salivary glands, vital organs for the biological success of the ticks. In addition, these glands act as storage sites for the pathogens transmitted to the host through the inoculation of the saliva. In this sense, the present study had the objective to analyze the behavior of male Wistar rat hepatic cells submitted to in vivo application of the salivary gland extract (SGE) obtained from R. sanguineus female ticks. The study involved five groups (four male adults each): CG (non-inoculated individuals); PBS1 (one phosphate buffer saline injection); PBS2 (two PBS injections); SGE1 (one injection of SGE at 0.04 MUg/MUL) and SGE2 (two injections of SGE at 0.04 MUg/MUL). After the exposures, the livers were removed and submitted to the following histological and histochemical stains: HE, toluidine blue, Xylidine Ponceau, alcian blue/PAS, and osmium-imidazole. The results showed that both the PBS and the SGE caused hepatic moderate alterations, such as: (a) emergence of lipid plaques among the hepatic cords; (b) cytoplasmic vacuolation of the hepatic cells; (c) hepatocytes showing pyknotic nuclei; (d) presence of homogeneous or granular secretion in the cytoplasm of the hepatocytes. Despite the slight morphological alterations observed in the hepatic cells and tissue, the latter did not show signs of disorganization after the exposure to the extracts. PMID- 30295367 TI - Evaluation of cell proliferation in cystic lesions associated with impacted third molars. AB - The purpose of this study was to evaluate the metabolism and epithelial cell proliferation of odontogenic keratocyst (OKC), dentigerous cyst (DC), and unicystic ameloblastoma (UA) by quantifying the nucleolar organizing regions (AgNORs) and Ki-67 protein immunoexpression. Forty-eight cases (16 OKC, 16 DC, and 16 UA) were evaluated retrospectively. The metabolism and epithelial cell proliferation was measured by the Ki-67 positive cell percentage index and by the mean AgNOR count in each group. The Ki-67 and AgNOR counts were significantly higher in OKC comparing to the DC and UA (p < .001). Ki-67 positive cells were observed higher in suprabasal cell layers of OKC with uniform distribution, a few of them were predominantly observed in basal cell layer in DC and UA. The AgNOR count was significantly higher in the OKC basal cell layers and observed throughout the lining epithelium of DC and UA. Ki-67 and AgNOR reinforced the aggressive character of OKC, presenting high metabolism and cellular proliferation compared to DC and UA, possibly due to its more aggressive clinical behavior and high recurrence rate.

AB - Full-arch, fixed, implant-supported prostheses can be designed to be cement- or screw-retained. Both retention mechanisms have a few inherent disadvantages. A fixed attachment system has been introduced to circumvent the disadvantages of both screw and cement retention. This system eliminates the screw access holes and the use of cement. The number of intraoral procedures required is also reduced. The purpose of this article is to report a case using the Locator F-Tx Attachment System to facilitate fabrication of an esthetic, clinician retrievable, full-arch implant-supported fixed dental prosthesis. PMID- 30295371 TI - A novel dynamic opto-thermo-mechanical stress testing device 2: In situ stretching process of polymeric fibers. AB - In this article, we used the opto-mechanical stress testing-device to stretch a monofilament of isotactic Polypropylene, iPP, fibers. This device was used to obtain the mechanical behavior of these fibers by measuring the complete stress strain curves at different stretching conditions. Using this device, the different regions of iPP fiber where the mechanical deformation takes place was characterized, including the necking region and fracture initiation process. The obtained mechanical behavior of iPP fibers was correlated to the variations of different optical parameters by attaching the device with the Pluta polarizing interference microscope. This microscope and the stress device allowed us to simultaneously measure the optical parameters and stress-strain data during stretching process at different stretching speeds. These data provide us with comprehensive information on the opto-mechanical behavior of polymeric fibers. Interferograms are included for illustration. PMID- 30295370 TI - A Pilot Study to Determine the Effect of Three Months of Oral Appliance Therapy using a Mandibular Advancement Device on HbA1c in Subjects with Type 2 Diabetes Mellitus and Obstructive Sleep Apnea. AB - PURPOSE: Continuous positive air pressure (CPAP) is recommended for obstructive sleep apnea (OSA) with type 2 diabetes mellitus (T2DM) but cost and compliance are major barriers. A mandibular advancement device (MAD) may be an economical, feasible alternative to CPAP. Various studies have been published to recommend MAD as an alternative to CPAP for OSA, but not regarding its efficacy for patients having OSA as well as T2DM. This study aims to objectively and subjectively evaluate oral appliance therapy using a MAD in patients having OSA as well as T2DM. MATERIALS AND METHODS: Patients who visited the hospital clinic having OSA as well as T2DM were recruited. After giving informed consent, participants were divided into three equally sized groups of three grades of OSA (mild, moderate, severe) on the basis of a polysomnography report and were given intervention of MAD at 50% of maximum mandibular protrusion and 20% of maximum interincisal opening. Objective outcomes were HbA1c level and apnea hypopnea index score (AHI). Subjective outcomes were Epworth Sleepiness Scale (ESS) and the Berlin Questionnaire. All outcomes were assessed before and after 3 months of intervention. RESULTS: A statistically significant difference was seen in all outcomes after intervention with MAD (p < 0.01) in all groups except HbA1c level in participants having severe OSA. CONCLUSION: MAD may be recommended in patients having OSA as well as T2DM. This study provides evidence to inform health care workers about possible use of MAD in OSA with T2DM. PMID- 30295372 TI - Irritating effects of sodium lauryl sulfate on human primary keratinocytes at subtoxic levels of exposure. AB - Chemical agents that can potentially cause skin irritation are typically tested in animal models or in vitro assays of cell viability or cytokine expression. However, these methods do not always provide translatable results and are not sufficiently sensitive for subtoxicity detection. Here, we introduce the mechanical properties of keratinocytes as novel endpoints for the safety assessment of chemical agents at the subtoxicity level. Human primary keratinocytes were treated with various concentrations of sodium lauryl sulfate (SLS) and their biological properties (proliferation, membrane integrity, inflammatory response, and morphology) were observed. Their biomechanical and geometrical parameters (stiffness and surface roughness) were also investigated by atomic force microscopy. Keratinocyte morphophysiological changes and inflammatory responses were significant at >=25 MUM SLS. The keratinocytes became less stiff due to changes in the distribution of F-actin filaments and alpha tubulin; these changes were significant even at lower doses of SLS (<=10 MUM). The morphophysiological changes of keratinocytes were clearly seen at a relatively high dose of SLS, while the mechanical properties of keratinocytes responded linearly to SLS at lower doses. Therefore, changes in mechanical properties can be used as new endpoints for in vitro toxicity testing with keratinocytes. PMID- 30295375 TI - Postural instability during attacks of migraine without aura. AB - BACKGROUND AND PURPOSE: Migraine has long been associated with unsteadiness and dizziness but postural control has not been studied in the ictal state. Here, the stability of upright stance during migraine attacks was measured. METHODS: Static balance was assessed prospectively in migraine patients (n = 30) during quiet stance for 40 s on a posturographic force platform. Recordings were performed both ictally and in the pain-free interval. Subjects were assessed under four different conditions yielding different visual and proprioceptive feedback environments. Both ictal and interictal data were compared with age-matched healthy controls (n = 30). RESULTS: Postural instability increased significantly under all experimental conditions during migraine attacks. Whilst standing on a foam pad with eyes closed, median sway area was 353 mm2 in control subjects, 318 mm2 in migraineurs in the pain-free period and 618 mm2 in the ictal state. However, Romberg and vestibular Romberg quotients were not altered during migraine attacks. Spectral analyses of postural sway also showed similar profiles in migraineurs and controls. The severity of headache was inversely correlated to Romberg quotients. CONCLUSIONS: The demonstrated pattern of balance disorder during migraine attacks suggests a transient cerebellar dysfunction. Our findings also indicate that intense headache induces a re-weighting of sensory processing toward less dependence on visual and proprioceptive information. PMID- 30295373 TI - Morphological alterations in the ovaries of Amblyomma cajennense semi-engorged ticks exposed to ethanolic extract of Acmella oleracea. AB - The present study analyzed the effects of different concentrations of Acmella oleracea crude ethanolic extract (EEAO) on the development of germ cells from semi-engorged Amblyomma cajennense females in order to evaluate the potential of this natural chemical as a strategy to control these important ectoparasites. A hundred semi-engorged females were divided into five groups (duplicates) (10 animals/group): Control 1 (distilled water); Control 2 (solvent ethanol 50% and DMSO 1%); and Treatment I to III (3.1, 6.2, and 12.5 mg/mL of EEAO, respectively). For the exposure of the ticks to the extract was used the Adult Immersion Test. After the exposition, the ovaries were removed and submitted to histological analysis using Harris hematoxylin and aqueous eosin. The histochemical tests were performed using PAS and Bromophenol blue staining techniques, for the detection of total polysaccharides and total protein, respectively. The extract caused significant alterations in the oocytes, including changes in the shape of the cells, disorganization, and cytoplasmic vacuolation, decrease in the number of yolk granules and germ vesicle fragmentation. These alterations were more intense in the oocytes in initial developmental stages (I and II). The results obtained in this study confirm the cytotoxic potential of the ethanolic extract of A. oleracea on the germ cells of A. cajennense females, opening up the possibility to use this extract as an alternative to control these ectoparasites. PMID- 30295376 TI - In-situ 2D bacterial crystal growth as a function of protein concentration: An atomic force microscopy study. AB - : The interplay between protein concentration and (observation) time has been investigated for the adsorption and crystal growth of the bacterial SbpA proteins on hydrophobic fluoride-functionalized SiO2 surfaces. For this purpose, atomic force microscopy (AFM) has been performed in real-time for monitoring protein crystal growth at different protein concentrations. Results reveal that (1) crystal formation occurs at concentrations above 0.08 uM and (2) the compliance of the formed crystal decreases by increasing protein concentration. All the crystal domains observed presented similar lattice parameters (being the mean value for the unit cell: a = 14.8 +/- 0.5 nm, b = 14.7 +/- 0.5 nm, gamma = 90 degrees +/- 2). Protein film formation is shown to take place from initial nucleation points which originate a gradual and fast extension of the crystalline domains. The Avrami equation describes well the experimental results. Overall, the results suggest that protein-substrate interactions prevail over protein protein interactions. RESEARCH HIGHLIGHTS: AFM enables to monitor protein crystallization in real-time. AFM high-resolution determines lattice parameters and viscoelastic properties. S-layer crystal growth rate increases with protein concentration. Avrami equation models protein crystal growth. PMID- 30295377 TI - Ultrastructural description of fresh and frozen/thawed sperm derived from collared peccaries (Pecari tajacu Linnaeus, 1,758). AB - The aim was to describe, through scanning electron microscopy (SEM) and transmission electron microscopy (TEM), the ultrastructure of peccaries' fresh and frozen-thawed sperm. For that, semen derived from three mature males was obtained by electroejaculation and evaluated for motility, membrane integrity, membrane functionality, chromatin integrity, and morphology through light microscopy. Samples were frozen using a Tris extender plus egg yolk (20%) and glycerol (6%). Then, fresh and frozen-thawed semen samples were mixed in different sperm pools that were processed for SEM and TEM. Sperm motility, membrane integrity, and functionality were impaired (p < .05) by freezing-thawing procedures, but sperm morphology, and chromatin integrity evaluated by light microscopy were not significantly affected. The SEM revealed that peccaries' sperm presents a flattened head in a paddle format, measuring 6.07 MUm in length and 3.84 MUm in width, with a vastus acrosome (4.46 MUm). Normal tails measure 38.11 MUm, being formed by an extensive midpiece with 15.52 MUm in length. In frozen-thawed samples, both SEM and TEM provide us information about damage undetected through light microscopy as the presence of vesicles in the acrosome, loose plasma membrane, vacuolized mitochondria, dense fibers disorganized, and decondensed chromatin. In conclusion, we provide the first description of the sperm ultrasctruture in collared peccaries. Moreover, SEM and TEM help us to identify some nanometric damage provoked by freezing-thawing procedures, thus providing valuable information for the improvement of such important protocols used for biobanking formation.

PMID- 30295374 TI - The Conometric Concept: A Two-Year Follow-Up of Fixed Partial CEREC Restorations Supported By Cone-In-Cone Abutments. AB - PURPOSE: To evaluate the performance of definitive, implant-supported, lithium disilicate fixed dental prostheses (LS2 FDPs) manufactured with a computer assisted design/computer-assisted manufacturing (CAD/CAM) system. All patients received two-unit restorations placed in posterior regions, supported by osseointegrated implants with cone-in-cone connection abutments. MATERIALS AND METHODS: Two implants (Ankylos) were placed into healed sites or fresh extraction sockets in the maxillary/mandibular posterior regions of partially edentulous patients. Definitive digital impressions were made 3 months after surgery. Twenty four patients received fixed monolithic LS2 restorations manufactured with the CEREC system. All restorations were connected to the implants using cone-in-cone connection abutments. Peri-implant pocket depths were recorded for 2 years at each follow-up visit. Esthetic, functional, and biologic United States Public Health Services (USPHS) parameters modified by the FDI World Dental Federation study design were assessed yearly until the last follow-up appointment. The opposing dentitions were identified by type of restoration and supporting structures at the time of placement of the definitive restorations and at the 2 year follow-up visits. RESULTS: One patient (4.16%) moved to an unknown location during the study. A total of 23 FDPs (95.8%) supported by 46 implants reached the 2-year follow-up. None of the prostheses failed, or became loose or detached. No significant difference involving probing levels between the experimental times were found. CONCLUSIONS: The results of this research indicated that the abutment prostheses connection using a cone-in-cone approach was successful within the 2 year period of this study.

AB - A 57-year-old Caucasian female presented to our clinic with her 23-year-old son, who was profoundly autistic. Our patient was convinced that her son had an infestation with fibers and believed that he had developed the condition as a young child. She described the symptoms of the infestation in her son's skin on his behalf, as he was not able to communicate. She identified dietary factors as a causative factor and wanted them removed from his diet. Her son had seborrhoeic dermatitis on examination, with no evidence of an infestation. Our patient later identified that fibers were coming out of her skin also. Her medical history included a road traffic accident resulting in back pain. Blood, urine, and microbiological investigations were normal. She was diagnosed with delusional infestation (DI) by proxy, and was started on risperidone. We present an interesting case of a patient with DI by proxy, in which the delusional beliefs of the mother have been projected onto her son. Issues of safeguarding vulnerable adults are raised in such cases, suggesting the crucial role of the physician in ensuring patient safety. DI by proxy has been reported in patients with children and animals, but we believe this is the first report of DI by proxy involving a vulnerable adult. PMID- 30295379 TI - Update of calcineurin inhibitors to treat inverse psoriasis: A systematic review. AB - Inverse psoriasis commonly involves skin fold areas including the axillae, perianal skin, intergluteal cleft, inframammary, genital/inguinal, abdominal, and retroauricular folds. Topical calcineurin inhibitors are indicated for the treatment of atopic dermatitis but have also been studied in the treatment of psoriasis. The object of the present study is to define the efficacy of topical calcineurin inhibitors in the treatment of psoriasis. We checked for English vernacular articles conveyed since 1990 in PubMed, Ovid/Cochrane, and Embase using "tacrolimus," "pimecrolimus," or "topical calcineurin inhibitors," and "psoriasis" as keywords. Eight double-blind studies and seven open studies displayed the ampleness of topical tacrolimus in psoriasis. Included studies demonstrated a considerable efficacy of topical administration of tacrolimus and pimecrolimus in the treatment of psoriasis, especially for facial, genital, and intertriginous areas. The role of topical tacrolimus and pimecrolimus in the treatment of psoriasis seems to be promising as shown by the results of double blind and open studies. Because these agents do not cause cutaneous atrophy, they have a special role in facial, genital, and intertriginous psoriatic lesions. Both agents await additional investigation to determine their roles. PMID- 30295382 TI - Penetrability of a new endodontic sealer: A confocal laser scanning microscopy evaluation. AB - : This study aimed to evaluate the penetration of a new endodontic sealer into the dentinal tubules. Twenty single-rooted teeth were selected. The crown was sectioned, and the canals were instrumented with a reciprocating system. Irrigation was performed with 2 mL of 2.5% sodium hypochlorite between each file change. After instrumentation, the root canals were irrigated with 2 mL of17% EDTA for 3 min followed by saline solution. The specimens were randomized into two groups (n =10) according to the endodontic sealer: AH Plus (AP) or Sealer Plus (SP). All specimens were filled using the lateral compaction technique. Rhodamine B dye (red) was incorporated to the sealers to provide the fluorescence which will enable confocal laser scanning microscopy (CLSM) assessment. The roots were sectioned 2, 4, and 6 mm from the apex and assessed by CLSM. The root canal level affected the penetration of the sealer, but no statistical significant differences were found between the two experimental groups (p > .05). SP presented similar dentinal penetration and perimeter integrity to the gold standard (AP). RESEARCH HIGHLIGHTS: Sealer Plus presents dentinal penetrability and perimeter integrity similar to the gold standard sealer (AH Plus), demonstrating excellent ability of filling areas of difficult access. PMID- 30295381 TI - The role of glucagon in the possible mechanism of cardiovascular mortality reduction in type 2 diabetes patients. AB - AIM: Type 2 diabetes (T2D) is one of the major public health issues worldwide. The main cause of mortality and morbidity among T2D patients are cardiovascular (CV) causes. Various antidiabetics are used in T2D treatment, but until recently they lacked clear evidence of the reduction in CV mortality and all-cause mortality as independent study end-points. The aim of this article was to present and critically evaluate potential mechanisms behind the remarkable results documented in trials with new antidiabetics for the treatment of T2D. METHODS: Relevant data were collected using the MEDLINE, PubMed, EMBASE, Web of Science, Science Direct, and Scopus databases with the key words: "type 2 diabetes," "mortality," "glucagon," "empagliflozin," "liraglutide," "insulin" and "QTc." Searches were not limited to specific publication types or study designs. RESULTS: The EMPA-REG OUTCOME trial with empagliflozin and LEADER trial with liraglutide presented remarkable results regarding the reduction in mortality in T2D treatment. However, the potential mechanism for those beneficial effects is difficult to determine. It is not likely that improvements in classic CV risk factors are responsible for the observed effect. A potential mechanism may be caused by the elevation of postprandial (PP) glucagon concentrations that can be seen with an empagliflozin and liraglutide therapy, which could have beneficial effects considering the myocardial electrical stability in T2D patients. CONCLUSION: This hypothesis throws new light upon possible mechanisms of reduction in mortality in T2D patients.

PMID- 30295385 TI - Seed surface ultrastructure as an efficient tool for species delimitation in the Allium ampeloprasum L. alliance (Amaryllidaceae, Allioideae). AB - Seed surface ultrastructure shows a wide variation among different species of the genus Allium that could potentially provide valuable characters in inferring the relationships. In order to evaluate inter- and intraspecific variation of testa microsculpturing in the leek alliance, 33 seed samples of Allium representing its two subgenera, six sections, and 23 species were studied. Seed testa surface was analyzed using both SEM and Stereomicroscopy. Minor differences in testa cell arrangement were observed between members of sect. Allium and sect. Avulsea (both of subg. Allium), but major contrasts were discerned between them and members of subg. Cepa. Significant similarity was distinguished in anticlinal walls of the members of sect. Allium and sect. Avulsea: they were variously undulated (U-, to +/-Omega-like). Testa cells in members of subg. Cepa, and some of subg. Allium (sect. Caerulea, sect. Codonoprasum, and sect. Longivaginata) showed ribbed anticlinal walls suggesting a close relationship between them. The periclinal walls were concave, flat to convex with testa cells densely granulose at margins in sect. Caerulea; flat to convex, irregularly granulose-verrucose in sect. Codonoprasum; concave, densely granulose at margins and center in sect. Longivaginata; and convex, densely irregularly granulose, sometimes centrally verrucose in subg. Cepa. Irregularly polygonal cells were present in most species, but elongated polygonal cells in two species, A. iranicum and A. wendelboi (sect. Allium). We found significant micromorphological similarity in seed surface features between A. abbasii and A. fuscoviolaceum; A. esfandiarii and A. atroviolaceum; and A. longipapillatum and A. rotundum, corroborating close relationships. PMID- 30295386 TI - The Evaluation of Color and Surface Roughness Changes in Resin based Restorative Materials with Different Contents After Waiting in Various Liquids: An SEM and AFM study. AB - : The aim of the study was to evaluate of surface roughness and color changes of the resin-based five restorative dental materials after aging in liquids at different pH values. Totally 250 specimens were prepared, including 50 specimens for the each material group from five different restorative materials (G1[Filtek Z550], G2[Beautifil II], G3[Vertise Flow], G4[Dyract XP], G5[GCFujiIILC]), using the 10-mm diameter and 2-mm thickness molds. A total of 50 specimens in the each group, were divided into five subgroups (n = 10) to be immerse into five liquids at different pH. After initial color and roughness measurements, samples were stored in the same liquids for 7 and 14 days and all of the measurements were repeated on the 7th and 14th days. scanning electron microscopy and atomic force microscopy analyses were performed in the all groups. When the color change(DeltaE) results are examined statistically; most of the DeltaE is in Fuji II LC; and at least in Filtek Z550, it was determined that cola and gastric acid had the greatest effect on DeltaE averages and showed significant differences (p < .05). When the average roughness values(Ra) are analyzed statistically, the highest values were found in Fuji II LC and the lowest values were found in Filtek Z550 (p < .05). The liquids which had the highest roughness average (DeltaRa) were statistically significant and gastric acid and orange juice were the most effective ones (p < .05). Asidic beverages significantly increased the surface roughness and discoloration of dental restorative materials. RESEARCH HIGHLIGHTS: The results of this research showed that dental restorative materials, which are resin-based, affected both the color and surface roughness after waiting in the low pH value beverages. These results are supported with the scanning electron microscopy and atomic force microscopy images in our research. Clinically, this situation will create esthetic and functional problems in the dental filling restorations. For this reason, the results of this study seem to be important and we think that this article could be contribute to the literature. PMID- 30295387 TI - Quantifying the legacy of snowmelt timing on soil greenhouse gas emissions in a seasonally dry montane forest. AB - The release of water during snowmelt orchestrates a variety of important belowground biogeochemical processes in seasonally snow-covered ecosystems, including the production and consumption of greenhouse gases (GHGs) by soil microorganisms. Snowmelt timing is advancing rapidly in these ecosystems, but there is still a need to isolate the effects of earlier snowmelt on soil GHG fluxes. For an improved mechanistic understanding of the biogeochemical effects of snowmelt timing during the snow-free period, we manipulated a high-elevation forest that typically receives over two meters of snowfall but little summer precipitation to influence legacy effects of snowmelt timing. We altered snowmelt rates for two years using black sand to accelerate snowmelt and white fabric to postpone snowmelt, thus creating a two- to three-week disparity in snowmelt timing. Soil microclimate and fluxes of carbon dioxide (CO2 ), methane (CH4 ), and nitrous oxide (N2 O) were monitored weekly to monthly during the snow-free period. Microbial abundances were estimated by potential assays near the end of each snow-free period. Although earlier snowmelt caused soil drying, we found no statistically significant effects (p < 0.05) of altered snowmelt timing on fluxes of CO2 or N2 O, or soil microbial abundances. Soil CH4 fluxes, however, did respond to snowmelt timing, with 18% lower rates of CH4 uptake in the earlier snowmelt treatment, but only after a dry winter. Cumulative CO2 emission and CH4 uptake were 43% and 88% greater, respectively, after the dry winter. We conclude that soil GHG fluxes can be surprisingly resistant to hydrological changes associated with earlier snowmelt, likely because of persistent moisture and microbial activities in deeper mineral soils. As a result, a drier California in the future may cause seasonally snow-covered soils in the Sierra Nevada to emit more GHGs, not less. PMID- 30295388 TI - Climate change opens new frontiers for marine species in the Arctic: Current trends and future invasion risks. AB - Climate change and increased anthropogenic activities are expected to elevate the potential of introducing nonindigenous species (NIS) into the Arctic. Yet, the knowledge base needed to identify gaps and priorities for NIS research and management is limited. Here, we reviewed primary introduction events to each ecoregion of the marine Arctic realm to identify temporal and spatial patterns, likely source regions of NIS, and the putative introduction pathways. We included 54 introduction events representing 34 unique NIS. The rate of NIS discovery ranged from zero to four species per year between 1960 and 2015. The Iceland Shelf had the greatest number of introduction events (n = 14), followed by the Barents Sea (n = 11), and the Norwegian Sea (n = 11). Sixteen of the 54 introduction records had no known origins. The majority of those with known source regions were attributed to the Northeast Atlantic and the Northwest Pacific, 19 and 14 records, respectively. Some introduction events were attributed to multiple possible pathways. For these introductions, vessels transferred the greatest number of aquatic NIS (39%) to the Arctic, followed by natural spread (30%) and aquaculture activities (25%). Similar trends were found for introductions attributed to a single pathway. The phyla Arthropoda and Ochrophyta had the highest number of recorded introduction events, with 19 and 12 records, respectively. Recommendations including vector management, horizon scanning, early detection, rapid response, and a pan-Arctic biodiversity inventory are considered in this paper. Our study provides a comprehensive record of primary introductions of NIS for marine environments in the circumpolar Arctic and identifies knowledge gaps and opportunities for NIS research and management. Ecosystems worldwide will face dramatic changes in the coming decades due to global change. Our findings contribute to the knowledge base needed to address two aspects of global change-invasive species and climate change. PMID- 30295389 TI - Bleeding events and safety outcomes in persons with haemophilia A with inhibitors: A prospective, multi-centre, non-interventional study. AB - INTRODUCTION: Prospectively collected, real-world data on bleeds, haemophilic treatment and safety outcomes in persons with haemophilia A (PwHA) with factor VIII (FVIII) inhibitors are limited. A prospective, global, multi-centre, non interventional study (NIS; NCT02476942) collected detailed real-world data in PwHA treated per local routine clinical practice. AIM: To characterize bleeding rates, haemophilic treatment practices, prophylaxis adherence and adverse events (AEs) in adult/adolescent PwHA with inhibitors in the NIS. METHODS: Participants aged >=12 years with congenital haemophilia A/documented high-titre FVIII inhibitor history were enrolled. Participants remained on their usual treatment; no interventions were applied. RESULTS: Overall, 103 PwHA with inhibitors enrolled, (median [range] age 31 [12-75] years) and were monitored for median (range) 26.0 (4.1-69.6) weeks. In the episodic (n = 75) and prophylactic (n = 28) treatment groups, respectively, 1244 and 325 bleeds were reported, and 528 (42.4%) and 104 (32.0%) were not treated; annualized bleeding rates (ABRs; 95% confidence interval) were 18.6 (15.2-22.8) and 14.9 (10.5-21.2) for treated bleeds, and 32.7 (27.3-39.1) and 25.0 (18.4-34.0) for all bleeds. Coagulation products used included activated prothrombin complex concentrate (aPCC) and/or recombinant activated FVII. Among participants prescribed aPCC prophylaxis, 35.0% adhered to both prescribed frequency of aPCC administration and prescribed dose. Serious AEs of haemarthrosis and muscle haemorrhage were reported; most common AEs were arthralgia, viral upper respiratory tract infection and pyrexia. CONCLUSIONS: ABRs (treated bleeds and all bleeds) remain high on standard treatment; this prospective NIS demonstrates the need for more effective treatments for PwHA with inhibitors to reduce/prevent bleeds, with potential to improve prophylaxis adherence and further improve outcomes. PMID- 30295390 TI - Ocean acidification increases iodine accumulation in kelp-based coastal food webs. AB - Kelp are main iodine accumulators in the ocean, and their growth and photosynthesis are likely to benefit from elevated seawater CO2 levels due to ocean acidification. However, there are currently no data on the effects of ocean acidification on iodine metabolism in kelp. As key primary producers in coastal ecosystems worldwide, any change in their iodine metabolism caused by climate change will potentially have important consequences for global geochemical cycles of iodine, including iodine levels of coastal food webs that underpin the nutrition of billions of humans around the world. Here, we found that elevated pCO2 enhanced growth and increased iodine accumulation not only in the model kelp Saccharina japonica using both short-term laboratory experiment and long-term in situ mesocosms, but also in several other edible and ecologically significant seaweeds using long-term in situ mesocosms. Transcriptomic and proteomic analysis of S. japonica revealed that most vanadium-dependent haloperoxidase genes involved in iodine efflux during oxidative stress are down-regulated under increasing pCO2 , suggesting that ocean acidification alleviates oxidative stress in kelp, which might contribute to their enhanced growth. When consumed by abalone (Haliotis discus), elevated iodine concentrations in S. japonica caused increased iodine accumulation in abalone, accompanied by reduced synthesis of thyroid hormones. Thus, our results suggest that kelp will benefit from ocean acidification by a reduction in environmental stress however, iodine levels in kelp-based coastal food webs will increase, with potential impacts on biogeochemical cycles of iodine in coastal ecosystems.

AB - Shift-work and exposure to light at night lead to circadian disruption, which favors the use of alcohol and may be a risk factor for development of addictive behavior. This study evaluated in two experimental models of circadian disruption behavioral indicators of elevated alcohol intake and looked for DeltaFosB, which is a transcription factor for neuronal plasticity in corticolimbic structures. Male Wistar rats were exposed to experimental shift-work (AR) or to constant light (LL) and were compared with a control group (LD). After 4 weeks in their corresponding conditions, control LD rats remained rhythmic, AR rats exhibited a loss of day-night patterns in the brain and the LL rats showed arrhythmicity in general activity and day-night PER1 patterns in corticolimbic structures. During 12 days of exposure to 10 percent alcohol solution, the AR group showed daily increased alcohol intake while LD and LL rats ingested similar amounts. After 72 h of alcohol deprivation, AR and LL rats increased alcohol intake in a binge-like test; this could be due not only to circadian disruption but also to stress and/or anxiety developed from the AR and LL manipulations. Associated to the increased alcohol intake, the AR and LL rats had significant accumulation of DeltaFosB in the nucleus accumbens shell and decreased DeltaFosB in the infralimbic cortex. Data here reported confirm that the disruption of temporal patterns favors the increased alcohol consumption and that this is associated with a differential accumulation of DeltaFosB which may favor the development of addictive behavior. PMID- 30295392 TI - Survey to estimate the prevalence of type 2 diabetes mellitus in hospital patients in Germany by systematic HbA1c measurement upon admission. AB - OBJECTIVES: The objective of this survey was to estimate the prevalence of type 2 diabetes mellitus (T2DM) in hospitalised patients >=55 years based on routine HbA1c measurement upon admission, using the diagnosis algorithm according to the German National Diabetes Care Guideline. DESIGN: Non-interventional survey. SETTING: Four German maximum care hospitals. POPULATION: Consecutive patients >=55 years of age admitted to hospital. MAIN OUTCOME MEASURES: Participating hospitals measured HbA1c upon admission and applied the algorithm for diagnosing T2DM per the clinical recommendations of the American Diabetes Association (ADA) and the German National Diabetes Care Guideline as part of the clinical routine and allocated patients to three diagnostic categories: T2DM, increased risk for T2DM, no T2DM. RESULTS: Between Oct 2014 and May 2015, the survey documented data from 6092 patients; the analyses included 5820 patients fulfilling validity criteria (95.5%). Of these, 1906 (32.7%) had a known history of T2DM. Among the 3914 remaining patients, 2181 had no T2DM (55.8%), 1180 an increased risk for T2DM (30.1%) and 553 unrecognised T2DM (14.1%; 95% CI: 13.1%-15.3%). The overall prevalence of known and unrecognised T2DM was 42.3% (95% CI: 41.0%-43.5%). Patients with previously unrecognised T2DM were admitted to hospital predominantly for cardiac disorders (21.9%), nervous system disorders such as cerebral infarction (15.0%) and infections/infestations (13.4%). CONCLUSIONS: This survey revealed an overall prevalence of known and unrecognised T2DM of more than 40%. Among patients with unrecognised T2DM on admission, the prevalence of T2DM was 14%. These data indicate that systematic documentation of T2DM in in patients is clinically useful. Hospitals should consider using the diagnostic algorithm and to streamline pathways of care to secure adequate care considering patients' diabetic risk profiles, and to manage related additional costs. PMID- 30295394 TI - Contribution of soil inorganic carbon to atmospheric CO2 : More important than previously thought. PMID- 30295393 TI - The greenhouse gas cost of agricultural intensification with groundwater irrigation in a Midwest U.S. row cropping system. AB - Groundwater irrigation of cropland is expanding worldwide with poorly known implications for climate change. This study compares experimental measurements of the net global warming impact of a rainfed versus a groundwater-irrigated corn (maize)-soybean-wheat, no-till cropping system in the Midwest US, the region that produces the majority of U.S. corn and soybean. Irrigation significantly increased soil organic carbon (C) storage in the upper 25 cm, but not by enough to make up for the CO2 -equivalent (CO2 e) costs of fossil fuel power, soil emissions of nitrous oxide (N2 O), and degassing of supersaturated CO2 and N2 O from the groundwater. A rainfed reference system had a net mitigating effect of 13.9 (+/-31) g CO2 e m-2 year-1 , but with irrigation at an average rate for the region, the irrigated system contributed to global warming with net greenhouse gas (GHG) emissions of 27.1 (+/-32) g CO2 e m-2 year-1 . Compared to the rainfed system, the irrigated system had 45% more GHG emissions and 7% more C sequestration. The irrigation-associated increase in soil N2 O and fossil fuel emissions contributed 18% and 9%, respectively, to the system's total emissions in an average irrigation year. Groundwater degassing of CO2 and N2 O are missing components of previous assessments of the GHG cost of groundwater irrigation; together they were 4% of the irrigated system's total emissions. The irrigated system's net impact normalized by crop yield (GHG intensity) was +0.04 (+/-0.006) kg CO2 e kg-1 yield, close to that of the rainfed system, which was -0.03 (+/ 0.002) kg CO2 e kg-1 yield. Thus, the increased crop yield resulting from irrigation can ameliorate overall GHG emissions if intensification by irrigation prevents land conversion emissions elsewhere, although the expansion of irrigation risks depletion of local water resources. PMID- 30295395 TI - Characterization of follicular minoxidil sulfotransferase activity in a cohort of pattern hair loss patients from the Indian Subcontinent. AB - Several studies have established that sulfotransferase enzyme activity in the outer root sheath of plucked hair follicles predicts response to topical minoxidil in the treatment of pattern hair loss. However, the prevalence of this enzyme activity among Indian patients has not been studied. Additionally, no reports in the literature characterize sulfotransferase activity based on sex, age, duration of hair loss, grade of hair loss, and family history. In this study we utilized a sulfotransferase activity assay first reported by Goren et al. We characterize the follicular sulfotransferase activity of 120 pattern hair loss patients visiting a dermatology outpatient clinic in India. Overall, 40.8% of patients with pattern hair loss had low levels of sulfotransferase. Surprisingly, 49.3% of men had low levels of sulfotransferase compared to 26.6% of women. No correlation was found between sulfotransferase activity and age, duration of hair loss, grade of hair loss, or family history. A sub-analysis of patient reported outcomes (PRO) validated previous findings that sulfotransferase enzyme activity is a predictive marker for minoxidil response in pattern hair loss patients. PMID- 30295396 TI - Hypothalamic response to cocaine cues and cocaine addiction severity. AB - The dopaminergic motive system is compromised in cocaine addiction. Abundant research has examined the roles of the dopaminergic midbrain and ventral striatum (VS) in cue-induced craving and habitual drug consumption. Interconnected with the dopaminergic circuits, the hypothalamus is widely implicated in motivated behavior, including food and drug seeking. However, very few studies have investigated how the hypothalamus responds to drug cues and whether hypothalamic responses are related to clinical features such as craving and addiction severity. Here, in 23 cocaine-dependent individuals (CD) exposed to cocaine vs neutral cues during functional magnetic resonance imaging (fMRI), we examined regional responses using established routines. At a corrected threshold, CD demonstrated increased activation to cocaine vs neutral cues in bilateral visual cortex, inferior parietal and middle frontal gyri, and the hypothalamus. The extent of hypothalamus but not other regional response was correlated with craving and cocaine addiction severity, each as assessed by the Cocaine Craving Questionnaire (CCQ) and Cocaine Selective Severity Assessment (CSSA). In contrast, subjective "acute" craving as elicited by cocaine cues during fMRI involved deactivation of bilateral orbitofrontal cortex (OFC) and angular gyri (AG), and the OFC and AG responses were not related to CCQ or CSSA score. These findings distinguished tonic craving as a critical factor in capturing cocaine addiction severity and substantiated a role of the hypothalamus in motivational dysfunction in cocaine addiction. PMID- 30295397 TI - The response of boreal peatland community composition and NDVI to hydrologic change, warming, and elevated carbon dioxide. AB - Widespread changes in arctic and boreal Normalized Difference Vegetation Index (NDVI) values captured by satellite platforms indicate that northern ecosystems are experiencing rapid ecological change in response to climate warming. Increasing temperatures and altered hydrology are driving shifts in ecosystem biophysical properties that, observed by satellites, manifest as long-term changes in regional NDVI. In an effort to examine the underlying ecological drivers of these changes, we used field-scale remote sensing of NDVI to track peatland vegetation in experiments that manipulated hydrology, temperature, and carbon dioxide (CO2 ) levels. In addition to NDVI, we measured percent cover by species and leaf area index (LAI). We monitored two peatland types broadly representative of the boreal region. One site was a rich fen located near Fairbanks, Alaska, at the Alaska Peatland Experiment (APEX), and the second site was a nutrient-poor bog located in Northern Minnesota within the Spruce and Peatland Responses Under Changing Environments (SPRUCE) experiment. We found that NDVI decreased with long-term reductions in soil moisture at the APEX site, coincident with a decrease in photosynthetic leaf area and the relative abundance of sedges. We observed increasing NDVI with elevated temperature at the SPRUCE site, associated with an increase in the relative abundance of shrubs and a decrease in forb cover. Warming treatments at the SPRUCE site also led to increases in the LAI of the shrub layer. We found no strong effects of elevated CO2 on community composition. Our findings support recent studies suggesting that changes in NDVI observed from satellite platforms may be the result of changes in community composition and ecosystem structure in response to climate warming. PMID- 30295398 TI - Delayed herbivory by migratory geese increases summer-long CO2 uptake in coastal western Alaska. AB - The advancement of spring and the differential ability of organisms to respond to changes in plant phenology may lead to "phenological mismatches" as a result of climate change. One potential for considerable mismatch is between migratory birds and food availability in northern breeding ranges, and these mismatches may have consequences for ecosystem function. We conducted a three-year experiment to examine the consequences for CO2 exchange of advanced spring green-up and altered timing of grazing by migratory Pacific black brant in a coastal wetland in western Alaska. Experimental treatments represent the variation in green-up and timing of peak grazing intensity that currently exists in the system. Delayed grazing resulted in greater net ecosystem exchange (NEE) and gross primary productivity (GPP), while early grazing reduced CO2 uptake with the potential of causing net ecosystem carbon (C) loss in late spring and early summer. Conversely, advancing the growing season only influenced ecosystem respiration (ER), resulting in a small increase in ER with no concomitant impact on GPP or NEE. The experimental treatment that represents the most likely future, with green-up advancing more rapidly than arrival of migratory geese, results in NEE changing by 1.2 umol m-2 s-1 toward a greater CO2 sink in spring and summer. Increased sink strength, however, may be mitigated by early arrival of migratory geese, which would reduce CO2 uptake. Importantly, while the direct effect of climate warming on phenology of green-up has a minimal influence on NEE, the indirect effect of climate warming manifest through changes in the timing of peak grazing can have a significant impact on C balance in northern coastal wetlands. Furthermore, processes influencing the timing of goose migration in the winter range can significantly influence ecosystem function in summer habitats. PMID- 30295399 TI - Natural history of a cohort of ABCD1 variant female carriers. AB - BACKGROUND AND PURPOSE: The therapeutic scenario of X-linked adrenoleukodystrophy (X-ALD) is rapidly changing. Whereas the disease is well characterized in men, the condition remains to be fully clarified in women carrying ATP binding cassette subfamily D member 1 (ABCD1) variants. Specifically, data on clinical progression are needed, in order to recommend any appropriate management. The objective of this study was to outline the natural history of a cohort of untreated ABCD1 heterozygous female carriers. METHODS: Longitudinal data from a single-center population of 60 carriers were retrospectively reviewed. Demographics, anthropometrics, serum very long chain fatty acid (VLCFA) levels, clinical parameters and the Adult ALD Clinical Score (AACS) were collected from every recorded visit in a 7-year period and analyzed to define the phenotype modifications, to determine factors associated with clinical features, and to estimate the annual progression rate and the subsequent sample size for interventional trials. RESULTS: Thirty-two patients were eligible for the study, and 59.4% were symptomatic at baseline. Clinical severity worsens with age which increases risk of symptom onset, the cut-off of 41 years being crucial for phenoconversion. VLCFA levels were not predictive and did not change over time. Symptomatic carriers were followed up for 3.45 +/- 2.1 years. The AACS increased at an annual rate of 0.24 points. The estimated sample size for 30% reduction in annual progression at 80% power was 272. CONCLUSIONS: This study provides data on the natural disease progression of untreated ABCD1 heterozygous female carriers, demonstrating the relevance of aging. The estimated annual increase of the AACS will be useful for future interventional studies. PMID- 30295400 TI - Preliminary evidence of different and clinically meaningful opioid withdrawal phenotypes. AB - Opioid use disorder (OUD) is a public health crisis. Differences in opioid withdrawal severity that predict treatment outcome could facilitate the process of matching patients to treatments. This is a secondary analysis of a randomized controlled trial (RCT) that enrolled treatment seeking heroin-users (N = 89, males = 78) into a residential study. Participants maintained on morphine (30 mg, subcutaneous, four-times daily) underwent a naloxone (0.4 mg, IM = intramuscular) challenge session to precipitate withdrawal. Area-under-the-curve (AUC) values from self-reported withdrawal ratings during the challenge session were analyzed using K-means clustering, revealing two phenotype groups. Withdrawal and retention from the subsequent 14-day double-blind, double-dummy RCT comparing three study medications (clonidine, tramadol-ER, and buprenorphine) were evaluated as a function of phenotype. Cluster analyses suggested HIGH (N = 37; mean [SD] subjective opiate withdrawal scale [SOWS]-AUC 123.7 [65.8]) and LOW (N = 52; SOWS-AUC 68.0 [47.7]) withdrawal phenotype groups. HIGH participants were significantly more female and had lower body mass indices than LOW participants; no drug-use variables were significant. Regarding RCT outcomes, HIGH phenotype participants were less likely to be retained in the study (P = 0.02) and had higher mean self-reported withdrawal (P = 0.05) than LOW phenotype participants. A significant interaction in RCT retention was observed between phenotype (P = 0.02) and study medication (P < 0.01). Self-reported withdrawal was significant for phenotype (P = 0.02); study medication trended towards significance (P = 0.07). Results suggest patients have meaningfully different experiences of opioid withdrawal that may predict differential response to opioid pharmacotherapies during supervised withdrawal. Additional prospective research to replicate and more thoroughly evaluate withdrawal phenotype correlates and sex differences is warranted. PMID- 30295401 TI - Consistent trophic amplification of marine biomass declines under climate change. AB - The impact of climate change on the marine food web is highly uncertain. Nonetheless, there is growing consensus that global marine primary production will decline in response to future climate change, largely due to increased stratification reducing the supply of nutrients to the upper ocean. Evidence to date suggests a potential amplification of this response throughout the trophic food web, with more dramatic responses at higher trophic levels. Here we show that trophic amplification of marine biomass declines is a consistent feature of the Coupled Model Intercomparison Project Phase 5 (CMIP5) Earth System Models, across different scenarios of future climate change. Under the business-as-usual Representative Concentration Pathway 8.5 (RCP8.5) global mean phytoplankton biomass is projected to decline by 6.1% +/- 2.5% over the twenty-first century, while zooplankton biomass declines by 13.6% +/- 3.0%. All models project greater relative declines in zooplankton than phytoplankton, with annual zooplankton biomass anomalies 2.24 +/- 1.03 times those of phytoplankton. The low latitude oceans drive the projected trophic amplification of biomass declines, with models exhibiting variable trophic interactions in the mid-to-high latitudes and similar relative changes in phytoplankton and zooplankton biomass. Under the assumption that zooplankton biomass is prey limited, an analytical explanation of the trophic amplification that occurs in the low latitudes can be derived from generic plankton differential equations. Using an ocean biogeochemical model, we show that the inclusion of variable C:N:P phytoplankton stoichiometry can substantially increase the trophic amplification of biomass declines in low latitude regions. This additional trophic amplification is driven by enhanced nutrient limitation decreasing phytoplankton N and P content relative to C, hence reducing zooplankton growth efficiency. Given that most current Earth System Models assume that phytoplankton C:N:P stoichiometry is constant, such models are likely to underestimate the extent of negative trophic amplification under projected climate change.

AB - Winter snow is an important driver of tree growth in regions where growing-season precipitation is limited. However, observational evidence of this influence at larger spatial scales and across diverse bioclimatic regions is lacking. Here, we investigated the interannual effects of winter (here defined as previous October to current February) snow depth on tree growth across temperate China over the period of 1961-2015, using a regional network of tree ring records, in situ daily snow depth observations, and gridded climate data. We report uneven effects of winter snow depth on subsequent growing-season tree growth across temperate China. There shows little effect on tree growth in drier regions that we attribute mainly to limited snow accumulation during winter. By contrast, winter snow exerts important positive influence on tree growth in stands with high winter snow accumulation (e.g., in parts of cold arid regions). The magnitude of this effect depends on the proportion of winter snow to pre-growing-season (previous October to current April) precipitation. We further observed that tree growth in drier regions tends to be increasingly limited by warmer growing-season temperature and early growing-season water availability. No compensatory effect of winter snow on the intensifying drought limitation of tree growth was observed across temperate China. Our findings point toward an increase in drought vulnerability of temperate forests in a warming climate. PMID- 30295403 TI - Diversity-Oriented Construction and Interconversion of Multicavity Supermacrocycles for Cooperative Anion-pi Binding. AB - A one-pot strategy for the diverse construction of a series of supermacrocycles was realized using rationally designed macrocyclic precursors. The base was found to have a significant effect not only on the size distribution but also on the structure of the supermacrocycles formed. While the use of less CsF (<4.0 equiv) afforded regular supermacrocycles containing up to four macrocyclic precursor subunits, the use of more CsF (>8.0 equiv) resulted in structurally reorganized supermacrocyles featuring oxacalix[2]arene[2]triazine motifs. Base-mediated supermacrocycle-to-supermacrocycle transformations were also revealed. With large cavities and many electron-deficient triazine moieties, the supermacrocyles can accommodate large organic anions via multiple anion-pi interactions as demonstrated for two supermacrocycles, which can host 2-carboxyacetate and represent the first crystallographic examples of sandwich-like structures with anion-pi interactions. PMID- 30295404 TI - Investigating the relationship between the HJHS and HAL in routine clinical practice: A retrospective review. AB - INTRODUCTION: Comprehensive musculoskeletal assessment for monitoring joint health in haemophilia includes both physical assessment with Haemophilia Joint Health Score (HJHS) and assessment of self-reported function by Haemophilia Activities List (HAL). METHODS: Correlation between physical assessment and joint function was undertaken between HJHS and HAL in patients with SHA and SHB who had both assessments at the same visit over a one-year period. RESULTS: Data from 120 patients (96-SHA/24 = SHB) with a median age 33 years (range 19-73) were included. Median total HJHS was 19, increasing with age: 18-30 years-7, 31-50 years-25 and 51-73 years-44. Similarly, median total HAL score was 80 with decreased function associated with increasing age: 18-30 years-90.4, 31-59 years 71.7, 51-73 years-49.5. Median Total HJHS and HAL demonstrated strong correlation (rs = 0.66, P < 0.01). Moderate-to-strong correlations were seen across the entire age group between the HJHS LL and UL subtotals and corresponding limb HAL domains. Within age groups, correlations were less significant particularly for the upper UL domains in HAL and the UL HJHS score. The wide range of ROM in joints categorized as markedly affected (ie, ROM loss score = 3) highlights the potential ceiling effect of this domain score and its use in chronically damaged joints. CONCLUSION: HJHS and HAL showed moderate-to-strong correlation with discrepancy in some individual patients. Prospective studies are required to better understand the clinical utility of both especially in severe joint disease where HAL may have a potential advantage. PMID- 30295405 TI - Trade-offs between soil carbon sequestration and reactive nitrogen losses under straw return in global agroecosystems. AB - It is widely recommended that crop straw be returned to croplands to maintain or increase soil carbon (C) storage in arable soils. However, because C and nitrogen (N) biogeochemical cycles are closely coupled, straw return may also affect soil reactive N (Nr) losses, but these effects remain uncertain, especially in terms of the interactions between soil C sequestration and Nr losses under straw addition. Here, we conducted a global meta-analysis using 363 publications to assess the overall effects of straw return on soil Nr losses, C sequestration and crop productivity in agroecosystems. Our results show that on average, compared to mineral N fertilization, straw return with same amount of mineral N fertilizer significantly increased soil organic C (SOC) content (14.9%), crop yield (5.1%), and crop N uptake (10.9%). Moreover, Nr losses in the form of nitrous oxide (N2 O) emissions from rice paddies (17.3%), N leaching (8.7%), and runoff (25.6%) were significantly reduced, mainly due to enhanced microbial N immobilization. However, N2 O emissions from upland fields (21.5%) and ammonia (NH3 ) emissions (17.0%) significantly increased following straw return, mainly due to the stimulation of nitrification/denitrification and soil urease activity. The increase in NH3 and N2 O emissions was significantly and negatively correlated with straw C/N ratio and soil clay content. Regarding the interactions between C sequestration and Nr losses, the increase in SOC content following straw return was significantly and positively correlated with the decrease in N leaching and runoff. However, at a global scale, straw return increased net Nr losses from both rice and upland fields due to a greater stimulation of NH3 emissions than the reduction in N leaching and runoff. The trade-offs between increased net Nr losses and soil C sequestration highlight the importance of reasonably managing straw return to soils to limit NH3 emissions without decreasing associated C sequestration potential. PMID- 30295406 TI - Donor-derived strongyloidiasis after organ transplantation in Norway. AB - Strongyloides stercoralis is an intestinal helminth which in humans can cause asymptomatic chronic infection maintained for decades through its auto-infective cycle. During solid organ transplantation, recipients may unintentionally receive an organ infected with strongyloides. This is a very rare complication but may have deadly outcome if not detected. We hereby report two transplant recipients whom developed Strongyloides hyperinfection syndrome after organ transplantation from the same deceased donor. Recipient 1 was kidney transplanted and presented at day 65 post engraftment with diarrhea and subsequent septicemia and gastric retention. Larvae were detected in gastric aspirate. Recipient 2 was simultaneously kidney and pancreas transplanted and presented at day 90 post engraftment also with gastric retention and septicemia. Larvae were demonstrated on duodenal biopsy and stool sample. The clinical course was complicated with severe duodenal bleedings, gastric retention, meningitis, and prolonged hospitalization. Retrospective testing of pre-transplant donor serum was positive for Strongyloides stercoralis antibodies. As a result of disease severity and gastric retention albenazole was administered via a jejunal tube and ivermectin subcutaneously in both recipients. S stercoralis was successfully eradicated and the transplants ended up with unaffected graft function. Following these two cases, we started systematic screening of all deceased donors for serum Strongyloides IgG in October 2016. After having screened 150 utilized donors one tested positive for Strongyloides, which initiated prophylactic ivermectin treatment to organ recipients. No symptoms or disease developed. Our center will continue to screen all donors as prophylactic treatment may avert this potentially lethal complication in cases of donor-derived Strongyloides infection. PMID- 30295407 TI - Effect of isavuconazole on tacrolimus and sirolimus serum concentrations in allogeneic hematopoietic stem cell transplant patients: A drug-drug interaction study. AB - INTRODUCTION: Isavuconazole, a triazole antifungal, is an inhibitor of cytochrome P450 3A4, which also metabolizes tacrolimus and sirolimus. In previous studies, isavuconazole administration increased tacrolimus and sirolimus area under the curve values by 2.3-fold and 1.8-fold, respectively, in healthy adults and tacrolimus concentration/dose (C/D) ratio by 1.3-fold in solid organ transplant patients. We aimed to determine the magnitude of effect of isavuconazole administration on tacrolimus and sirolimus C/D ratios in allogeneic hematopoietic stem cell transplant (alloHSCT) patients. METHODS: A retrospective, single center, single-arm study in adult alloHSCT patients who received at least 10 days of combination therapy with isavuconazole and tacrolimus and/or sirolimus as inpatients or outpatients was conducted. Tacrolimus and sirolimus trough serum concentrations were measured up to twice weekly for up to 4 weeks. RESULTS: Twenty-two patients receiving tacrolimus and twenty patients receiving sirolimus met the inclusion criteria. The mean C/D ratio increased from baseline by 1.42 fold for tacrolimus during week 1 (P = 0.002) and up to 1.56-fold for sirolimus during week 2 (P = 0.02). For the remaining timepoints, tacrolimus and sirolimus C/D ratios were not statistically significantly different from baseline. CONCLUSION: In alloHSCT patients, modest increases in tacrolimus and sirolimus C/D ratios from baseline were observed within the first 2 weeks after initiation of isavuconazole. PMID- 30295408 TI - Effect of adjuvant radiotherapy on the local recurrence of oral squamous cell carcinoma with perineural invasion: A systematic review. AB - OBJECTIVES OF THE REVIEW: The decision whether to include postoperative radiotherapy on patients with oral squamous cell carcinoma depends on the risk of local recurrence. The objectives of this study were to systematically review literature on whether perineural invasion in oral squamous cell carcinoma patients is associated with higher local recurrence rates and whether local recurrence is influenced by the administration of postoperative radiotherapy in patients presenting with perineural invasion. TYPE OF REVIEW: Systematic review. SEARCH STRATEGY: Embase, PubMed, Web Of Science. EVALUATION METHOD: The databases above were searched for studies that analysed: the treatment of oral squamous cell carcinoma patients with perineural invasion, local recurrence and postoperative radiotherapy. The data of seven studies were analysed qualitatively. RESULTS: The overall quality of the studies was moderate to low. There was no evidence of the effect of postoperative radiotherapy on local recurrence rates in patients presenting with perineural invasion. Some evidence suggests that local recurrence rates may increase in cases of multifocal perineural invasion, especially if nerves >1 mm are involved but these data should be interpreted with caution due to the low-quality evidence. CONCLUSIONS: High-quality evidence regarding the prognostic value of perineural invasion and the impact of postoperative radiotherapy in patients presenting with perineural invasion is lacking in the literature, making it difficult to select a postoperative strategy for early-stage tumours. PMID- 30295409 TI - Withdrawal from long-term use of zopiclone, zolpidem and temazepam may improve perceived sleep and quality of life in older adults with primary insomnia. AB - Long-term use of benzodiazepines or benzodiazepine receptor agonists is widespread, although guidelines recommend short-term use. Only few controlled studies have characterized the effect of discontinuation of their chronic use on sleep and quality of life. We studied perceived sleep and quality of life in 92 older (age 55-91 years) outpatients with primary insomnia before and after withdrawal from long-term use of zopiclone, zolpidem or temazepam (BZDA). BZDA was withdrawn during 1 month, during which the participants received psychosocial support and blindly melatonin or placebo. A questionnaire was used to study perceived sleep and quality of life before withdrawal, and 1 month and 6 months later. 89 participants completed the 6-month follow-up. As melatonin did not improve withdrawal, all participants were pooled and then separated based solely on the withdrawal results at 6 months (34 Withdrawers. 55 Nonwithdrawers) for this secondary analysis. At 6 months, the Withdrawers had significantly (P < 0.05) shorter sleep-onset latency and less difficulty in initiating sleep than at baseline and when compared to Nonwithdrawers. Compared to baseline, both Withdrawers and Nonwithdrawers had at 6 months significantly (P < 0.05) less fatigue during the morning and daytime. Stress was alleviated more in Withdrawers than in Nonwithdrawers (P < 0.05). Satisfaction with life and expected health 1 year later improved (P < 0.05) in Withdrawers. In conclusion, sleep disturbances, daytime fatigue and impaired quality of life may resolve within 6 months of BZDA withdrawal. These results encourage withdrawal from chronic use of benzodiazepine type hypnotics, particularly in older subjects. PMID- 30295410 TI - Randomized and controlled study comparing patient controlled and radiologist controlled intra-procedural conscious sedation, using midazolam and fentanyl, for patients undergoing insertion of a central venous line. AB - INTRODUCTION: Interventional Radiology procedures can provoke anxiety and may be painful. Current practice, Radiologist Controlled Sedation (RCS), involves titrating aliquots of midazolam and fentanyl to patient response but underdosing and overdosing may occur. This study tests a new method of titrating sedation/analgesia during the procedure, Patient Controlled Sedation (PCS), in which a combination of fentanyl and midazolam are administered using a patient controlled analgesia pump. This allows the patient to self-control their sedation/analgesia during the procedure. METHODS: We performed a randomised control trial comparing the effects of pain, sedation, amnesia and overall patient satisfaction between PCS and RCS, by enrolling forty patients undergoing insertion of a tunnelled central line. RESULTS: Our results showed that PCS was safe, with no adverse events. PCS was effective in providing sedation, amnesia and overall pain relief comparable to RCS. There was no significant difference in dose given to patients using PCS or RCS. There was a tendency for patients in the PCS group to begin sedation later than those in the RCS group, but both were equally sedated during the procedure. We show that patients in the PCS group were very satisfied with the procedure. CONCLUSIONS: We show that PCS is non-inferior to RCS in terms of dosage given and degree of sedation. To the authors' knowledge, this is the first study to show intra-procedural PCS in an Interventional Radiology setting using midazolam and fentanyl as a randomised comparative trial. It has wide applicability in a procedural setting for very low cost and with minimal additional training required. PMID- 30295411 TI - Androgen deprivation therapy use with post-prostatectomy radiotherapy in the Prostate Cancer Outcomes Registry Victoria. AB - INTRODUCTION: The aim of this study is to evaluate the use of androgen deprivation therapy (ADT) with post-prostatectomy radiotherapy (PPRT) in a population-based cohort of Australian men. METHODS: This is a prospective cohort of men with localised prostate cancer captured in the Prostate Cancer Outcomes Registry Victoria (PCOR-Vic), who received PPRT between January 2010 and December 2015. The primary outcome was ADT use with PPRT. Multivariate logistic regressions were used to identify patient, tumour and institutional factors influencing ADT use. RESULTS: 485 men were included in this study - 115 (24%) had pT2 disease, 231 (48%) pT3a, 134 (28%) pT3b and 5 (1%) pT4. Eighteen (4%) men had ISUP grade 1 disease, 139 (29%) ISUP grade 2, 170 (35%) ISUP grade 3 and 158 (33%) ISUP grade 4/5, while 267 (64%) men had positive surgical margins. Median time from prostatectomy to PPRT was 8.1 months (IQR = 5.3-13.9). Sixty-six (14%) patients had ADT with PPRT. In multivariate analyses, men who had increased age (OR = 1.06; 95% CI = 1.01-1.11), seminal vesicle involvement (OR = 3.81; 95% CI = 1.63-8.91) and underwent treatment in regional centres (OR = 2.17; 95% CI = 1.08 4.33) were more likely to have ADT with PPRT. CONCLUSION: We reported that 14% of men treated with PPRT received ADT in a population-based cohort of Australian men, which was less than half of the proportion of ADT use with PPRT in the US. It will be of interest to evaluate the uptake of ADT with PPRT in the coming years following recent publications of level 1 evidence confirming overall survival benefits of ADT with PPRT. PMID- 30295412 TI - Risk of hepatitis B reactivation in hepatitis B surface antigen seronegative and core antibody seropositive kidney transplant recipients. AB - BACKGROUND: Previous contact with Hepatitis B virus (HBV) is common in patients undergoing hemodialysis. Literature has shown conflicting results on the risk of HBV reactivation in kidney transplant (KT) recipients with serologic evidence of past HBV infection. METHODS: We reviewed 631 consecutive KT recipients and selected 70 patients simultaneously HBsAg negative and anti-HBc positive before KT, regardless of hepatitis B surface antibody (anti-HBs) status. Demographic characteristics, coinfection with other viruses, the presence of a previous KT, induction and maintenance immunosuppression, length of follow up, biopsy-proven acute rejection episodes, incidence of impaired liver function, and causes of graft loss and mortality were collected. Hepatitis B virus reactivation was defined as detection of HBV DNA viral load >2000 IU/mL during follow up. Outcome data included HBV reactivation episodes, graft function, and patient survival. RESULTS: Median follow-up was 151 months; 91.4% of patients were positive to anti HBs prior to KT. No patient received HBV prophylaxis and 11 patients (15.7%) received rituximab as part of induction therapy. Anti-HBs titers remained stable in all patients throughout the observation period but two patient showed evidence of HBV reactivation after KT. CONCLUSION: Hepatitis B virus reactivation in HBsAg negative and anti-HBc-positive after KT is rare but possible. We suggest evaluating HBV serologies, HBV DNA viral load, and liver enzymes before KT and routinely monitoring serologic HBV markers after KT. As only two patients experienced HBV reactivation, it is neither possible to define risk factors for HBV reactivation nor to evaluate the impact of different immunosuppressants or the benefit of prophylactic regimens. Further studies regarding HBV reactivation in solid organ transplant recipients are necessary. PMID- 30295413 TI - Stanozolol promotes lipid deposition in the aorta through an imbalance in inflammatory cytokines and oxidative status in LDLr knockout mice fed a normal diet. AB - The aim of the study was to evaluate the effect of an anabolic steroid, stanozolol, in a model of atherosclerosis and to investigate the involvement of the modulation of the inflammatory cytokines and oxidative stress in vascular lipid deposition. Low-density lipid receptor-deficient (LDLr-/-) mice were fed a standard chow diet and were each week injected subcutaneously either saline (control C group) or 20 mg/kg stanozolol (S group). After 8 weeks, the levels of cholesterol, oxidized LDL (OxLDL) and cytokines were measured in plasma, lipid deposition in aorta was evaluated by en face analysis, and thiobarbituric acid reactive substances and oxidation protein were determined in liver. The S group demonstrated increases in vascular lipid deposition, triglycerides and non-HDL cholesterol levels. Stanozolol increased tumour necrosis factor alpha (TNF-alpha) and decreased interleukin-10 as well as increased the TNF-alpha/IL-10 ratio. Furthermore, oxidative stress was observed in the S group, as indicated by an increase in the plasma OxLDL, as well as by lipid peroxidation and oxidation of proteins in the liver. Chronic treatment with stanozolol promoted lipid deposition in the LDLr-/- mice that could be attributed to a modification of the circulating cytokine levels and systemic oxidative stress. Our results suggest that the anabolic steroid stanozolol in the absence of functional LDL receptors by increasing systemic inflammation and oxidative stress may increase the risk of development and progression of atherosclerosis.

PMID- 30295422 TI - Persistently Frequent Emergency Department Utilization among Persons with Systemic Lupus Erythematosus. AB - OBJECTIVE: To evaluate SLE patients who persistently frequent the ED to identify opportunities to improve outpatient care. METHODS: We conducted a retrospective study of SLE patients who frequented the ED for >=3 visits in a calendar year from 2013-2016. Persistent users met criteria for frequent use for at least 2 out of the 4 years, and limited users for 1 out of the 4 years. Each ED encounter was categorized as; SLE-, infection-, pain- related, or "other". We compared ED use between persistent and limited users, and analyzed factors associated with pain related encounters among persistent users through multivariate logistic regression. RESULTS: We identified 77 participants having 1143 encounters as persistent users, and 52 participants having 335 encounters as limited users. Persistent users accounted for 77% of ED use by SLE patients who frequented the ED. Pain-related ED visits were more common among persistent users (32%) than limited users (18%). Among persistent users, most pain-related encounters were discharged from the ED (69%) or within 48 hours of admission (20%). Persistent users with pain-related encounters accounting for >10% of ED use, were more likely to be obese, have fewer comorbid conditions, and be on LTOT. CONCLUSION: Pain is major cause of ED use. SLE patients persistently utilizing the ED for pain are likely to be non-critically ill, as evidenced by frequent discharges from the ED and short stay admissions. SLE patients who persistently frequent the ED for pain represent a viable target for interventions to improve outpatient quality of care. This article is protected by copyright. All rights reserved. PMID- 30295423 TI - Relationship between esophageal abnormalities on fluoroscopic esophagram and pulmonary function testing in juvenile systemic sclerosis. AB - OBJECTIVE: Juvenile systemic sclerosis (jSSc) is a disabling autoimmune condition that affects multiple organs in addition to skin, notably the gastrointestinal and pulmonary systems. The relationship between esophageal abnormalities and pulmonary disease in jSSc is not well understood. We describe associations between radiologic esophageal abnormalities and pulmonary function. METHODS: Clinical and radiographic data of children less than 18 years who fulfilled 2007 Pediatric Rheumatology Provisional Classification Criteria for jSSc between 1994 and 2016 were reviewed. Fluoroscopic upper gastrointestinal studies (UGI), high resolution chest computed tomography (HRCT), and pulmonary function testing (PFTs) within 12 months of presentation to Seattle Children's Hospital were extracted. RESULTS: 21 children with jSSc (67% female, 8-17 years) were studied. Esophageal abnormalities, defined as abnormal esophageal peristalsis and/or bolus clearance, were found in 12 patients. Abnormal esophagus on UGI was not associated with gastrointestinal or pulmonary symptoms, disease duration, use of medications (proton pump inhibitor or immunosuppressant), or specific autoantibodies. Compared with patients with a normal esophagus on UGI, children with an abnormal esophagus had decreased PFTs: mean FEV1 96% vs. 78% (p=0.03), FVC 94% vs. 76% (p=0.02), and VC 95% vs. 76% (p=0.02). Children with an abnormal esophagus on UGI had a larger mean esophageal diameter on HRCT, (14.6 mm compared to 8.5 mm, p<0.01). CONCLUSION: There was an association between esophageal and pulmonary disease in children with jSSc. Esophageal findings on UGI or HRCT, despite lack of symptoms, should raise concern for esophageal dysfunction and prompt heightened surveillance for concurrent lung disease.

AB - SIRT1 is an NAD+ -dependent deacetylase that functions in a variety of cells and tissues to mitigate age-associated diseases. However, it remains unknown if SIRT1 also acts to prevent pathological changes that accrue in motor neurons during aging and amyotrophic lateral sclerosis (ALS). In this study, we show that SIRT1 expression decreases in the spinal cord of wild-type mice during normal aging. Using mouse models either overexpressing or lacking SIRT1 in motor neurons, we found that SIRT1 slows age-related degeneration of motor neurons' presynaptic sites at neuromuscular junctions (NMJs). Transcriptional analysis of spinal cord shows an overlap of greater than 90% when comparing alterations during normal aging with changes during ALS, revealing a substantial upregulation in immune and inflammatory response genes and a downregulation of synaptic transcripts. In addition, overexpressing SIRT1 in motor neurons delays progression to end-stage disease in high copy SOD1G93A mice. Thus, our findings suggest that there are parallels between ALS and aging, and interventions to impede aging may also slow the progression of this devastating disease. PMID- 30295424 TI - Relationship between hip morphology and hip-related patient-reported outcomes in young and middle-aged individuals: A population-based study. AB - OBJECTIVES: Radiographic measurements of alpha angle and lateral centre edge (LCE) angle in the hip joint are important for the diagnosis of femoroacetabular syndrome, a potential risk factor for hip osteoarthritis. Our objective was to determine if these measurements are associated with hip-related patient-reported outcomes (PROs) in young and middle-aged individuals. Methods A stratified random sample of Caucasian men and women aged 20-49 years, with and without hip pain, was selected using random digit dialling from the population of Metro Vancouver, Canada. The alpha and LCE angles were measured bilaterally on x-ray using Dunn and AP views, respectively. PROs were measured by the Copenhagen Hip And Groin Outcome Score (HAGOS), which has scales for symptoms, pain, daily activities, sports, physical activity, and quality of life (QOL). We performed descriptive analyses and a regression analysis with restricted cubic splines (RCS), adjusted for age and sex and weighted for the sampling design. RESULTS: Data were obtained for 500 subjects. The alpha angle distribution was strongly skewed with a mean at 54O . The LCE angle distribution was symmetric with a mean of 34O . In the RCS analysis, the relationship between alpha angle and HAGOS scores was non-linear, with higher alpha generally associated with worse HAGOS scores for alpha>60O . The associations were statistically significant for symptoms, sports, and QOL. No association was found between the LCE angle and HAGOS scales. CONCLUSIONS: In a general population sample aged 20-49, we have found an association between alpha angle and hip-related patient-reported outcomes. This article is protected by copyright.

AB - OBJECTIVE: The short-term outcomes of remission-targeted treatments of rheumatoid arthritis (RA) are well-established, but the long-term success of such strategies is speculative, as is the role of early add-on biologics. We assessed the 10-year outcomes of patients with early RA treated with initial remission-targeted triple combination of conventional synthetic disease-modifying antirheumatic-drugs (csDMARDs), 7.5 mg prednisolone (PRD) and additional infliximab or placebo infusions. METHODS: Ninety-nine patients with early, DMARD-naive RA were treated with a triple combination of csDMARDs and PRD, and randomized to double-blindly receive either infliximab (FIN-RACo+INFL) or placebo (FIN-RACo+PLA) infusions during the first 6 months. After 2 years, the treatment strategies became unrestricted, but the treatment goal was strict NEO-RACo remission. At 10 years, the clinical and radiographic outcomes and the drug treatments used between 5-10 years were assessed. RESULTS: Ninety patients (91%) were followed after 2 years, 43 in the FIN-RACo+INFL and 47 in the FIN-RACo+PLA group. At 10 years, the respective proportions of patients in strict NEO-RACo and in DAS28 remissions in the FIN-RACo+INFL and FIN-RACo+PLA groups were 46% and 38% (p=0.46), and 82% and 72% (p=0.29). The mean total Sharp van der Heijde score was 9.8 in the FIN RACo+INFL and 7.3 in the FIN-RACo+PLA group (p=0.34). During the 10-year follow up 26% of the FIN-RACo+INFL group and 30% of the FIN-RACo+PLA group patients had received biologics (p=0.74). CONCLUSION: In early RA, excellent results can be maintained up till 10 years in most patients treated with initial combination csDMARDs and remission-targeted strategy, regardless of initial infliximab/placebo infusions.

PMID- 30295426 TI - Sacroiliac Joint Ankylosis In Young Spondyloarthritis Patients Receiving Biologic Therapy: Observation of Serial MRI scans. AB - OBJECTIVES: To assess the temporal relationship between initiating biologic therapy and magnetic resonance imaging (MRI) scores of inflammation and structural damage in young patients with spondyloarthritis. METHODS: A local adolescent rheumatology database was searched for patients aged 12 - 24 years with sacroiliitis on MRI and a clinical diagnosis of enthesitis-related arthritis (ERA) or non-radiographic axial spondyloarthritis. Patients treated with tumour necrosis factor inhibitor (TNFi) therapy with a minimum of one scan before and two after starting TNFi therapy (over >= 2 years) were included. Images of the sacroiliac joints were scored for inflammation and structural abnormalities (including erosions, fat metaplasia and fusion). The effects of TNFi therapy and of time since initiation of TNFi therapy on inflammation and structural abnormalities were assessed using a mixed-effects regression analysis. RESULTS: Twenty-nine patients aged 12-23 years undergoing TNFi therapy were included. Inflammation scores were significantly lower in patients on treatment (P=0.013), but there was no significant effect of time from TNFi initiation on inflammation (P=0.125). Conversely, there was no significant effect of treatment itself on fusion scores (P=0.285), but fusion scores significantly increased with time from TNFi initiation (P=0.000). A similar pattern was observed for fat metaplasia. Fusion scores did not change in the first year after starting TNFi therapy (P=0.108), but were significantly increased at all subsequent time points (P=0.000 to 0.001). CONCLUSIONS: TNFi therapy failed to prevent the eventual development of joint ankylosis in this cohort, despite a substantial reduction in inflammation with TNFi therapy.

AB - OBJECTIVE: Pain is one of the main complaints of patients with rheumatoid arthritis (RA). Pain in RA is caused by specific physical changes, such as joint destruction, and is therefore used as a disease activity marker. Although pain can also be influenced by emotional factors, neither the effect of emotional health nor the indirect effect of physical state mediated by emotional health on pain has been quantified. METHODS: A total of 548 patients with RA participated. Emotional health was assessed using the Hospital Anxiety and Depression Scale (HADS). Measures routinely used in practice were used to evaluate physical state and pain. To quantify 1) the effects of physical state on emotional health, and 2) the effects of both physical and emotional health on pain, we used structural equation modelling with emotional health, physical state, and pain as latent variables. RESULTS: The prevalence of anxiety and depression (HADS score >=8 for each) among RA patients was 18.7% and 29.4%, respectively. Emotional health was significantly influenced by physical state (beta = 0.21). Pain was affected by physical (beta = 0.54) and emotional health (beta = 0.29). The effect of physical state on pain was mediated by emotional health, with this mediation effect (beta = 0.06) accounting for 10.2% of the total effect. CONCLUSION: The magnitude of pain in RA is determined by the mediation effect of emotional health as well as the direct physical state. Our findings suggest that emotional factors should be taken into account when assessing RA disease activity. This article is protected by copyright. All rights reserved.

AB - BACKGROUND: Increased herpes zoster (HZ) has been observed with janus kinase inhibitors such as tofacitinib. However, it is unclear whether concomitant methotrexate (MTX) and/or glucocorticoids (GC) confer additional (additive or multiplicative) risk. We evaluated HZ risk in tofacitinib users with and without MTX and GC. METHODS: Within MarketScan and Medicare data (2011-2016) we identified all rheumatologist-diagnosed RA patients initiating tofacitinib (index date); demographics and baseline covariates were evaluated in the year prior to index date. HZ was ascertained using ICD9/10 codes with anti-viral drug use (+-7 days). Multivariable (MV) Cox regression was used to evaluate hazard ratios (HRs) for HZ in tofacitinib users with and without current concomitant MTX and GC, controlling for baseline covariates. RESULTS: We studied 8,030 new tofacitinib users (83.3% women). Mean (SD) age was 60.3 (12.6) years. HZ incidence in tofacitinib users was numerically lowest in the absence of GC (3.4/100py with MTX; 3.7/100py without MTX). An approximately two-fold increased incidence of HZ was observed for tofacitinib users receiving either GCs alone (6.0/100 py) or both MTX+GCs (6.5/100py). The adjusted HR for HZ in tofacitinib users was unchanged (HR=0.99, 95%CI 0.64-1.54) when given only with MTX but was increased (HR=1.96, 95%CI 1.33-2.88) for tofacitinib+glucocorticoids. Older age and female sex were also risk factors, while prior vaccination was associated with a strong trend for lower risk. CONCLUSION: In tofacitinib users, HZ occurred at a rate of approximately 4% per year and was further doubled with GC exposure. Concomitant MTX did not confer additional risk. Zoster vaccination may decrease risk. This article is protected by copyright. All rights reserved. PMID- 30295429 TI - Safety and Immunogenicity of Rituximab Biosimilar GP2013 After Switch from Reference Rituximab in Patients with Active Rheumatoid Arthritis. AB - OBJECTIVES: Comparable clinical efficacy of the rituximab biosimilar GP2013 and reference rituximab (RTX) has been established in blinded randomized trials. However, when switching from a reference biologic to a biosimilar, potential safety implications are often an important consideration. Therefore, this study evaluated the safety of switching from reference RTX to rituximab biosimilar GP2013, compared with treatment continuation with reference RTX, in patients with rheumatoid arthritis (RA). METHODS: In this multinational randomized, double blind, parallel-group safety study, 107 patients with RA, who had previously received any duration of treatment with reference RTX as part of routine practice and who required a continuation of treatment, were randomized to receive either GP2013 or to continue reference RTX, both given with methotrexate and folic acid. Study assessments included incidence of hypersensitivity, infusion-related and anaphylactic reactions, immunogenicity (anti-drug antibodies [ADA]), and general safety. RESULTS: Whether patients switched to GP2013 or continued reference RTX, the incidences of hypersensitivity (9.4% versus 11.1%, respectively) and infusion related reactions (11.3% versus 18.5%, respectively) were similarly low. Only one patient in the reference RTX group developed ADA to rituximab after start of study treatment. No neutralizing ADAs were observed. ADAs were not associated with adverse events (AEs). No clinically meaningful differences in the rate of AEs were observed between treatment groups. CONCLUSION: No safety risks were detected when patients switched from reference RTX to GP2013. The safety profiles of patients in both treatment groups were similar, although the study was not powered for statistical safety equivalence testing. This article is protected by copyright.

AB - OBJECTIVE: To compare and contrast perspectives of patients with arthritis and rehabilitation professionals on starting and sustaining use of physical activity trackers (PATs). METHODS: We conducted focus groups with patients, physiotherapists, and occupational therapists, in Ontario, Alberta or British Columbia, Canada. To be eligible, patients reported a diagnosis of inflammatory or osteo- arthritis. Rehabilitation professionals reported at least 40% of their caseload dedicated to arthritis care. Participants had any level of experience with PATs. A thematic analytic approach was used. RESULTS: Three themes were identified: 1) Anticipating sharing objective measures of physical activity: Participants agreed PATs had potential to improve consultations between patients with arthritis and rehabilitation professionals, but were uncertain as to how to achieve this potential; 2) Perceived or experienced barriers to start or continue using a PAT: Participants shared doubts about whether existing PATs would meet specific needs of patients with arthritis, expressing concern about possible negative impacts; 3) Bolstering motivation?: While there was agreement that PATs could bolster patients' motivation if they were already active, patients and rehabilitation professionals felt differently about whether PATs alone would motivate patients to start increasing activity levels. CONCLUSION: Our study highlights similarities and differences among patient and rehabilitation professional perspectives on the potential value and risks of integrating PATs into arthritis self-management. Despite agreement about PATs' potential, participants were uncertain about how to effectively incorporate these tools to enhance patient-clinician consultations and held differing views about whether PATs would support patients' motivation to be active.

AB - The aim of this case report is to assess the potential role of intrarenal Doppler ultrasonography as a non-invasive method to evaluate intrarenal venous flow (IRVF) in acute heart failure (AHF) and concomitant renal dysfunction. We report a case of an 81-year-old woman with valvular heart disease (previous mitral valve replacement) that presented with acutely decompensated heart failure and concomitant worsening renal function (WRF). In addition to complete physical examination, laboratory analysis, and echocardiography, IRVF was assessed at baseline and 48 h after the administration of diuretic treatment. At admission, physical examination and echocardiography revealed signs of intravascular congestion (jugular venous distension and severely dilated inferior vena cava). In addition, a significant increase in serum creatinine from 1.23 to 1.81 mg/dL was noted without signs of hypoperfusion at clinical evaluation. At baseline, intrarenal Doppler ultrasonography showed a monophasic IRVF pattern indicating a severely elevated interstitial renal pressure. After aggressive decongestion, a dynamic behaviour was found in IRVF changing from monophasic to biphasic pattern in parallel with an improvement in clinical parameters and renal function (serum creatinine changed from 1.81 to 1.44 mg/dL). In this case of a patient with AHF and WRF, IRVF changed after aggressive decongestion in agreement with clinical evolution. According to these findings, this technique could provide valuable information for identifying patients with a 'congestion kidney failure' phenotype. Further studies are needed confirming this observation and evaluating the potential role of this technique for guiding decongestive therapy in patients with AHF and WRF. PMID- 30295432 TI - Central sensitisation in knee osteoarthritis: Relating pre-surgical brainstem neuroimaging and PainDETECT based patient stratification to arthroplasty outcome. AB - OBJECTIVES: The neural mechanisms of pain in knee OA are not fully understood: some patients have neuropathic-like pain, associated with central sensitisation. We aimed to identify central sensitisation using neuroimaging and PainDETECT, and relate it to post-arthroplasty outcome. METHODS: Patients awaiting arthroplasty underwent quantitative sensory testing, psychological assessment and functional neuroimaging (fMRI). fMRI was conducted during punctate (n=24) and cold pain stimulation (n=20) to the affected knee. Post-operative outcome was measured using: Oxford Knee Score; moderate to severe long-term pain after arthroplasty and a range of pain-related questionnaires. RESULTS: Patients with neuropathic like pain pre-surgery, identified using PainDETECT, reported significantly higher pain to punctate and cold stimuli, near the affected joint. In these patients and when compared to those without neuropathic-like pain, neural activity was significantly lower in the rostral anterior cingulate cortex and higher in the rostral ventromedial medulla (RVM) during punctate stimulation, with significant functional connectivity between these two areas. Pre-operative neuropathic-like pain and higher neural activity in the RVM was associated with moderate to severe long-term pain after arthroplasty. CONCLUSION: The psychophysical and neuroimaging data suggest that a subset of OA patients have centrally mediated pain sensitisation. This is likely due to supraspinally mediated reductions in inhibition, and increases in facilitation of nociceptive signaling, and was associated with a worse outcome following arthroplasty. The neurobiological confirmation of central sensitisation in patients with features of neuropathic pain, identified using PainDETECT, provides further support for the investigation of such bed-side measures for patient stratification to better predict post surgical outcome.

PMID- 30295434 TI - Long-Term Safety of Rituximab in Rheumatoid Arthritis: Analysis From the SUNSTONE Registry. AB - OBJECTIVE: To evaluate the long-term safety of rituximab in an observational cohort of patients with rheumatoid arthritis (RA) who had an inadequate response to >= 1 antitumor necrosis factor therapies in the United States (SUNSTONE Registry). METHODS: In this prospective, observational cohort study, patients received rituximab according to their physician's standard practice and were evaluated at standard-of-care follow-up visits at least every 6 months. The primary outcome was the incidence of protocol-defined significant infections. Secondary outcomes included serious adverse events potentially associated with rituximab, cardiovascular or thrombotic (CVT) events, seizures, deaths and pregnancies. Posthoc analyses assessed outcomes by concomitant medication use. RESULTS: Overall, 989 patients (safety-evaluable population) received >= 1 dose of rituximab, with a total follow-up of 3844 patient-years (PYs; mean duration, 3.9 years). In total, 341 significant infections occurred in 197 patients (19.9%). The incidence rates (95% CI) for significant infections, CVT events, and seizures were 8.87 (7.98, 9.86), 1.95 (1.56, 2.45), and 0.18 (0.09, 0.38) per 100 PYs, respectively. The incidence of significant infections did not increase with time or with cumulative rituximab exposure. During the study, 64 patients died (crude mortality [95% CI]: 1.66 per 100 PYs [1.30, 2.13]). The most common causes of death were infections (19 patients), malignancy (14), and cardiovascular events (13). Eight pregnancies were reported in 7 patients. CONCLUSION: In patients with RA treated with rituximab for up to 5 years, the rates of significant infections were stable over time and higher in patients who received long-term systemic steroid treatment.

AB - This review focuses on the effects of chronic systemic inflammation on skeletal muscle and its downstream effect on physical function in individuals with rheumatoid arthritis (RA). The importance of skeletal muscle in the regulation of whole-body glucose and lipid metabolism, and the benefits and barriers to physical activity and exercise training are highlighted. Finally, we identify knowledge gaps that may be important for the development of both pharmacologic and non-pharmacologic interventions (e.g. proper exercise regimens) to protect individuals with RA from physical impairment.

AB - We appreciate Dr. Kuwabara's sharing FEATHER study data in relation to our article2 about the cardiovascular safety of febuxostat and allopurinol in patients with gout and cardiovascular morbidities (CARES) trial. As pointed out, we agree that the FEATHER study's overall cardiovascular (CV) disease outcome results4 tended to be consistent with the CARES trial findings, although its sample size was >10 time smaller than the CARES trial and underpowered for that purpose. The author states no difference of CV mortality, but no data are provided, although the number of CV deaths would be less than the overall CV event rates (4/219 in febuxostat and 7/222 in placebo).4 To that end, these data appear to add minimally to the causal inference about the CV impact of febuxostat.

AB - AIMS: We conducted a prospective study of emergency department (ED) patients with acute heart failure (AHF) to determine if worsening HF (WHF) could be predicted based on urinary electrolytes during the first 1-2 h of ED care. Loop diuretics are standard therapy for AHF patients. A subset of patients hospitalized for AHF will develop a blunted natriuretic response to loop diuretics, termed diuretic resistance, which often leads to WHF. Early detection of diuretic resistance could facilitate escalation of therapy and prevention of WHF. METHODS AND RESULTS: Patients were eligible if they had an ED AHF diagnosis, had not yet received intravenous diuretics, had a systolic blood pressure > 90 mmHg, and were not on dialysis. Urine electrolytes and urine output were collected at 1, 2, 4, and 6 h after diuretic administration. Worsening HF was defined as clinically persistent or WHF requiring escalation of diuretics or administration of intravenous vasoactives after the ED stay. Of the 61 patients who qualified in this pilot study, there were 10 (16.3%) patients who fulfilled our definition of WHF. At 1 h after diuretic administration, patients who developed WHF were more likely to have low urinary sodium (9.5 vs. 43.0 mmol; P < 0.001) and decreased urine sodium concentration (48 vs. 80 mmol/L; P = 0.004) than patients without WHF. All patients with WHF had a total urine sodium of <35.4 mmol at 1 h (100% sensitivity and 60% specificity). CONCLUSIONS: One hour after diuretic administration, a urine sodium excretion of <35.4 mmol was highly suggestive of the development of WHF. These relationships require further testing to determine if early intervention with alternative agents can prevent WHF.

AB - OBJECTIVE: Reports on quadriceps weakness as a risk factor for incident and progressive knee osteoarthritis are conflicting, potentially due to differing effects of muscle strength on patellofemoral and tibiofemoral compartments. This study aimed to examine the sex-specific relation of quadriceps strength to worsening patellofemoral and tibiofemoral cartilage damage over 84-months. METHODS: The Multicenter Osteoarthritis Study (MOST) is a cohort study of individuals with or at risk for knee osteoarthritis. Maximal quadriceps strength was assessed at baseline. Cartilage damage was semi-quantitatively assessed by magnetic resonance images (MRIs) at baseline and 84-month follow-up using the Whole-Organ MRI Score (WORMS). Worsening patellofemoral and tibiofemoral cartilage damage was defined as any WORMS score increase in each subregion within medial and lateral compartments separately. Logistic regression with generalised estimating equations was used to assess the sex-specific relation of quadriceps strength to worsening cartilage damage. RESULTS: 1,018 participants (mean age 61+/-8 years, and BMI 29.3+/-4.5 kg/m2 ; 64% female) were included. Quadriceps weakness increased the risk of worsening lateral patellofemoral cartilage damage in women (risk ratio for lowest vs. highest quartile of strength: 1.50 (95% confidence interval: 1.03, 2.20); linear trend p=0.007) but not in men. There was generally no association between quadriceps weakness and worsening cartilage damage in the medial or lateral tibiofemoral compartment for either women or men. CONCLUSION: Low quadriceps strength increased the risk of worsening cartilage damage in the lateral patellofemoral joint of women suggesting that optimising quadriceps strength may help prevent worsening of structural damage in the patellofemoral joint in women.

AB - BACKGROUND: Hidradenitis suppurativa (HS) is a chronic, disabling, inflammatory skin disorder that primarily affects the hair follicle localized at the apocrine gland-bearing areas of the body, including axillary, inguinal, buttocks, and anogenital areas, and it may be associated with a wide array of comorbid conditions. This study aimed to described comorbid conditions affecting HS patients and to detect any correlation with disease severity. METHODS: Analyzing clinic database, we included all charts of patients visited at the HS outpatient clinic of three University Dermatologic Departments in order to describe demographic data, anthropometric measures, disease features, personal habits, clinical history, and presence of comorbidities. RESULTS: Two hundred thirty-four patients, mostly females (62%), were enrolled in this study. Based on Hurley staging classification 41% of patients were classified as Hurley Stage I, 43.0% as Hurley II, and 16% Hurley III, with a mean mSartorius score value of 24.7 (SD: +/-19.39) and a mean AISI score value of 12.5 (SD: +/-11.93). The most frequently observed comorbidities were: obesity (26.1%), polycystic ovary syndrome (PCOS) (13.8% of the overall study population and 22.3% of females), hypertension (11.9%), dyslipidemia (9.9%), type II diabetes (9.5%), thyroid disorders (9.1%), nervous system disorders (7.1%), acne (6.7%), metabolic syndrome (4.4%), and Crohn's disease (3.6%). Obesity represented a key-comorbid condition increasing the likelihood of having more severe HS and PCOS (odds ratio 3.35 and 3.74, respectively). CONCLUSIONS: HS is associated with a variety of comorbid conditions that should be considered to perform targeted routine screening and to improve HS management.

PMID- 30295450 TI - Low Interface Energies Tune the Electrochemical Reversibility of Tin Oxide Composite Nanoframes as Lithium-Ion Battery Anodes. AB - The conversion reaction of lithia can push up the capacity limit of tin oxide based anodes. However, the poor reversibility limits the practical applications of lithia in lithium-ion batteries. The latest reports indicate that the reversibility of lithia has been appropriately promoted by compositing tin oxide with transition metals. The underlying mechanism is not revealed. To design better anodes, we studied the nanostructured metal/Li2O interfaces through atomic scale modeling and proposed a porous nanoframe structure of Mn/Sn binary oxides. The first-principles calculation implied that because of a low interface energy of metal/Li2O, Mn forms smaller particles in lithia than Sn. Ultrafine Mn nanoparticles surround Sn and suppress the coarsening of Sn particles. Such a composite design and the resultant interfaces significantly enhance the reversible Li-ion storage capabilities of tin oxides. The synthesized nanoframes of manganese tin oxides exhibit an initial capacity of 1620.6 mA h g-1 at 0.05 A g-1. Even after 1000 cycles, the nanoframe anode could deliver a capacity of 547.3 mA h g-1 at 2 A g-1. In general, we demonstrated a strategy of nanostructuring interfaces with low interface energy to enhance the Li-ion storage capability of binary tin oxides and revealed the mechanism of property enhancement, which might be applied to analyze other tin oxide composites. PMID- 30295451 TI - Self-Regenerating Soft Biophotovoltaic Devices. AB - This paper describes the fabrication of soft, stretchable biophotovoltaic devices that generate photocurrent from photosystem I (PSI) complexes that are self assembled onto Au electrodes with a preferred orientation. Charge is collected by the direct injection of electrons into the Au electrode and the transport of holes through a redox couple to liquid eutectic gallium-indium (EGaIn) electrodes that are confined to microfluidic pseudochannels by arrays of posts. The pseudochannels are defined in a single fabrication step that leverages the non Newtonian rheology of EGaIn. This strategy is extended to the fabrication of reticulated electrodes that are inherently stretchable. A simple shadow evaporation technique is used to increase the surface area of the Au electrodes by a factor of approximately 106 compared to planar electrodes. The power conversion efficiency of the biophotovoltaic devices decreases over time, presumably as the PSI complexes denature and/or detach from the Au electrodes. However, by circulating a solution of active PSI complexes the devices self regenerate by mass action/self-assembly. These devices leverage simple fabrication techniques to produce complex function and prove that photovoltaic devices comprising PSI can retain the ability to regenerate, one of the most important functions of photosynthetic organisms. PMID- 30295453 TI - Progressive Micromodulation of Interlayer Coupling in Stacked WS2/WSe2 Heterobilayers Tailored by a Focused Laser Beam. AB - When a vertically stacked heterobilayer comprising of a WSe2 monolayer on a WS2 monolayer is first fabricated, the heterobilayer behaves like two independent monolayers because of the presence of a large interlayer separation. However, after the stacked heterobilayer is subjected to a focused laser treatment, the interlayer separation between the two monolayers becomes progressively reduced which transforms the WS2/WSe2 heterostructure from the noncoupling to the strongly coupling regime. This strong coupling induces the charge transfer between two layers and thus lowers the exciton recombination rate in the individual layer. This changes the optical properties of the heterobilayer from a fluorescence-active species into one where the fluorescence is quenched. The focused laser beam scanning method is therefore able to serve as a localized annealing tool to progressively modulate the interlayer separation and enable the micropatterning of the heterobilayer to achieve distinct regions with different degrees of fluorescence quenching. Systematic studies are carried out to gain an insight into the mechanism involved in the onset of the interlayer coupling in the material. Our method is also successfully extended to a WS2/WS2 homobilayer structure.

AB - A liquid-permeable concept in a metal-insulator-metal (MIM) structure is proposed to achieve highly sensitive color-tuning property through the change of the effective refractive index of the dielectric insulator layer. A semicontinuous top metal film with nanoapertures, adopted as a transreflective layer for MIM resonator, allows to tailor the nanomorphology of a dielectric layer through selective etching of the underneath insulator layer, resulting in nanopillars and hollow voids in the insulator layer. By allowing outer mediums to enter into the hollow voids of the dielectric layer, such liquid-permeable MIM architecture enables to achieve the wavelength shift as large as 323.5 nm/RIU in the visible range, which is the largest wavelength shift reported so far. Our liquid permeable approaches indeed provide dramatic color tunablility, a real-time sensing scheme, long-term durability, and reproducibility in a simple and scalable manner. PMID- 30295454 TI - Ultra-Small Platinum Nanoparticles Encapsulated in Sub-50 nm Hollow Titania Nanospheres for Low-Temperature Water-Gas Shift Reaction. AB - Ultra-small platinum nanoparticles loaded over titania is a promising catalyst for the low-temperature water-gas shift (WGS) reaction and shows the potential to work in a mobile hydrogen fuel cell system. Their precise size engineering (<3 nm) and reliable stabilization remain challenging. To address these issues, we report a reverse-micelle synthesis approach, which affords uniform ultra-small platinum nanoparticles (tunable in ~1.0-2.6 nm) encapsulated in hollow titania nanospheres with a shell thickness of only ~3-5 nm and an overall diameter of only ~32 nm. The Pt@TiO2 yolk/shell nanostructured catalysts display extraordinary stability and monotonically increasing activity with the decreasing size of the Pt nanoparticles in the WGS. The size-dependent variation in the electronic property of the Pt nanoparticles and the reducible oxide encapsulation that prevents the Pt nanoparticles from sintering are ascribed as the main reasons for the excellent catalytic performance. PMID- 30295455 TI - Walnut-like Transition Metal Carbides with Three-Dimensional Networks by a Versatile Electropolymerization-Assisted Method for Efficient Hydrogen Evolution. AB - Mo2C@NPC (N,P-doped carbon) electrocatalysts are developed on carbon cloth (CC) as binder-free cathodes for efficient hydrogen evolution through a facile route of electropolymerization followed by pyrolysis. Electropolymerization of pyrrole to form polypyrrole occurs with the homogeneous incorporation of PMo12, driven by Coulombic force between the positively charged polymer backbone and PMo12 anions. This electrochemical synthesis is easily scaled up, requiring neither complex instrumentation nor an intentionally added electrolyte (PMo12 also acts as an electrolyte). After pyrolysis, the resultant Mo2C@NPC/CC electrode exhibits a unique interconnected walnut-like porous structure, which ensures strong adhesion between the active material and the substrate and favors electrolyte penetration into the electrocatalyst. This method is effective with other monomers such as aniline and is readily extended to fabricate other metal carbide electrodes such as WC@NPC/CC. These carbide electrodes exhibit high catalytic performance for hydrogen production, for example, WC@NPC/CC can deliver an unprecedented current density of 600 mA cm-2 at an overpotential of only 200 mV either in an acidic or an alkaline solution. Considering the simplicity, scalability, and versatility of the synthetic method, the unique electrode structure, and the excellent catalysis performance, this study opens up new avenues for the design of various novel binder-free metal carbide cathodes based on electropolymerization. PMID- 30295456 TI - Polydopamine-Derived Nitrogen-Doped Carbon-Covered Na3V2(PO4)2F3 Cathode Material for High-Performance Na-Ion Batteries. AB - Nitrogen-doped carbon-covered Na3V2(PO4)2F3 (NVPF/C-PDPA) composites have been successfully prepared by self-polymerization of dopamine on the NVPF surface and subsequent sintering. The X-ray diffraction results show that the NVPF/C-PDPA has good crystallinity and introducing dopamine does not affect the lattice structure of NVPF. The high-resolution transmission electron microscopy, high-angle annular dark-field images, and energy dispersive X-ray spectroscopy analyses reveal that the NVPF/C-PDPA particles are covered by a complete and uniform covering layer, which is effective at preventing corrosion of NVPF in the electrolyte to greatly increase cycling stability. Furthermore, N-doping into the carbon layer can produce additional active sites to improve the capacity especially the rate capacity. Such a NVPF/C-PDPA electrode delivers a remarkable rate capacity (98.0 mA h g-1 at 10 C) and superior cycle performance (~95.8% capacity retention at 10 C after 800 cycles). We believe that this work may be beneficial for accelerating the development of high-performance electrode materials and the commercialization of Na-ion batteries. PMID- 30295457 TI - Gold Nanoparticles Biosynthesized and Functionalized Using a Hydroxylated Tetraterpenoid Trigger Gene Expression Changes and Apoptosis in Cancer Cells. AB - Understanding the synthetic mechanisms and cell-nanoparticle interactions of biosynthesized and functionalized gold nanoparticles (AuNPs) using natural products is of great importance for developing their applications in nanomedicine. In this study, we detailed the biotransformation mechanism of Au(III) into AuNPs using a hydroxylated tetraterpenoid deinoxanthin (DX) from the extremophile Deinococcus radiodurans. During the process, Au(III) was rapidly reduced to Au(I) and subsequently reduced to Au(0) by deprotonation of the hydroxyl head groups of the tetraterpenoid. The oxidized form, deprotonated 2 ketodeinoxanthin (DX3), served as a surface-capping agent to stabilize the AuNPs. The functionalized DX-AuNPs demonstrated stronger inhibitory activity against cancer cells compared with sodium citrate-AuNPs and were nontoxic to normal cells. DX-AuNPs accumulated in the cytoplasm, organelles, and nuclei, and induced reactive oxygen species generation, DNA damage, and apoptosis within MCF-7 cancer cells. In the cells treated with DX-AuNPs, 374 genes, including RRAGC gene, were upregulated; 135 genes, including the genes encoding FOXM1 and NR4A1, were downregulated. These genes are mostly involved in metabolism, cell growth, DNA damage, oxidative stress, autophagy, and apoptosis. The anticancer activity of the DX-AuNPs was attributed to the alteration of gene expression and induction of apoptosis. Our results provide significant insight into the synthesis mechanism of AuNPs functionalized with natural tetraterpenoids, which possess enhanced anticancer potential. PMID- 30295458 TI - Paper-Derived Flexible 3D Interconnected Carbon Microfiber Networks with Controllable Pore Sizes for Supercapacitors. AB - Heteroatom-doped three-dimensional (3D) carbon fiber networks have attracted immense interest because of their extensive applications in energy-storage devices. However, their practical production and usage remain a great challenge because of the costly and complex synthetic procedures. In this work, flexible B, N, and O heteroatom-doped 3D interconnected carbon microfiber networks (BNOCs) with controllable pore sizes and elemental contents were successfully synthesized via a facile one-step "chemical vapor etching and doping" method using cellulose made paper, the most abundant and cost-effective biomass, as an original network frame precursor. Under a rational design, the BNOCs exhibited interconnected microfiber-network structure as expressways for electron transport, spacious accessible surface area for charge accumulation, abundant mesopores and macropores for rapid inner-pore ion diffusion, and lots of functional groups for additional pseudocapacitance. Being applied as binder-free electrodes for supercapacitors, BNOC-based supercapacitors not only revealed a high specific capacitance of 357 F g-1, a high capacitance retention of 150 F g-1 at 200 A g-1, a high energy density of 12.4 W h kg-1, and a maximum power density of 300.6 kW kg-1 with an aqueous electrolyte in two-electrode configuration but also exhibited a high specific capacitance of up to 242.4 F g-1 in an all-solid-state supercapacitor.

AB - Rechargeable magnesium batteries (RMBs) have attracted a lot of attention in recent decades due to the theoretical properties of these systems in terms of energy density, safety, and price. Nevertheless, to date, fully rechargeable magnesium battery prototypes with sufficient longevity and reversibility were realized only with low voltage and low capacity intercalation cathode materials based on Cheverel phases. The community is therefore actively looking for high capacity cathodes that can work with metallic magnesium anodes in viable RMB systems. One of the most promising cathode materials, in terms of very high theoretical specific capacity, is, naturally, sulfur. A number of recent works studied the electrochemical performances of rechargeable sulfur cathodes in RMB, with success to some extent on the cathode side. Nevertheless, as known from the lithium-sulfur rechargeable battery systems, the formation of soluble polysulfides during discharge affects strongly the behavior of the anode side. In this article and the work it describes, we focus on soluble polysulfides impact on Mg-S electrochemichal systems. We carefully designed herein conditions that mimic the Mg-S battery prototypes containing balanced Mg and elemental sulfur electrodes. Under these conditions, we extensively studied the Mg anode behavior. The study shows that when elemental sulfur cathodes are discharged in the Mg-S cells containing electrolyte solutions in which Mg anodes behave reversibly, the polysulfide species thus formed migrate to the anode and eventually fully passivate it by the formation of very stable surface layers. The work involved electrochemical, spectroscopic, and microscopic studies. The present study clearly shows that to realize practical rechargeable Mg-S batteries, the transport of any sulfide moieties from the sulfur cathode to the magnesium anode has to be completely avoided. Such a condition is mandatory for the operation of secondary Mg-S batteries.

AB - Lightweight energy storage technologies are integral for powering emerging wearable health monitors and smart garments. In-plane, interdigitated microsupercapacitors (MSCs) hold the greatest promise to be integrated into wearable electronics because of their miniaturized footprint, as compared to conventional, multilayered supercapacitors and batteries. Constructing MSCs directly on textiles, while retaining the fabric's pliability and tactile quality, will provide uniquely wearable energy storage systems. However, relative to plastic-backed or paper-based MSCs, garment-integrated MSCs are underreported. The challenge lies in creating electrochemically active fiber electrodes that can be turned into MSCs. We report a facile vapor deposition and sewing sequence to create rugged textile MSCs. Conductive threads are vapor-coated with a stably p doped conducting polymer film and then sewn onto a stretchy textile to form three dimensional, compactly aligned electrodes with the electrode dimensions defined by the knit structure of the textile backing. The resulting solid-state device has an especially high areal capacitance and energy density of 80 mF/cm2 and 11 MUW h/cm2 with a polymer gel electrolyte, and an energy density of 34 MUW h/cm2 with an ionic liquid electrolyte, sufficient to power contemporary iterations of wearable biosensors. These textile MSCs are also super deformable, displaying unchanging electrochemical performance after fully rolling-up the device.

AB - Data-independent acquisition methods that acquire fragment ions from virtually any peptide in a sample have expanded the benefits of low-throughput targeted proteomics to proteome-wide analyses. While these methods have increased the reproducibility of peptide quantification across multiple samples, their sensitivity is still limited, and the quantification of complete proteomes remains a challenge. Here we present DIA+, a DIA method that combines signals from identical peptides with different charge states, resulting in improved signal-to-noise, additional number of fragments, and therefore in a higher number of identified and quantified peptides in complex samples. PMID- 30295462 TI - Nucleic Acid Detection by a Target-Assisted Proximity Proteolysis Reaction. AB - Nucleic acid analysis plays an important role in diagnosing diseases as well as understanding biology. Despite advances in technology, there is still a need to develop a rapid and simple method to detect specific nucleic acids, especially in remote locations and low-resource cases. Here, we proposed a proximity proteolysis reaction in which the reaction between protease and zymogen is enhanced in the presence of a target molecule. The pair of proteins was site specifically modified with oligonucleotides, and the conjugates were used to develop a method of detecting nucleic acids. Target DNA and RNA could be detected in less than 1 h at sub-nanomolar concentrations based on an absorbance signal. The assay method was resistant to interference by biological matrixes, and its sensitivity could be improved when combined with an isothermal nucleic acid amplification method. The results demonstrated the feasibility of this proximity proteolysis reaction as a new platform technology for detecting specific nucleic acid sequences. PMID- 30295463 TI - Electronic Structure Tunability by Periodic meta-Ligand Spacing in One Dimensional Organic Semiconductors. AB - Designing molecular organic semiconductors with distinct frontier orbitals is key for the development of devices with desirable properties. Generating defined organic nanostructures with atomic precision can be accomplished by on-surface synthesis. We use this "dry" chemistry to introduce topological variations in a conjugated poly( para-phenylene) chain in the form of meta-junctions. As evidenced by STM and LEED, we produce a macroscopically ordered, monolayer thin zigzag chain film on a vicinal silver crystal. These cross-conjugated nanostructures are expected to display altered electronic properties, which are now unraveled by highly complementary experimental techniques (ARPES and STS) and theoretical calculations (DFT and EPWE). We find that meta-junctions dominate the weakly dispersive band structure, while the band gap is tunable by altering the linear segment's length. These periodic topology effects induce significant loss of the electronic coupling between neighboring linear segments leading to partial electron confinement in the form of weakly coupled quantum dots. Such periodic quantum interference effects determine the overall semiconducting character and functionality of the chains.

AB - Real-time monitoring of the distribution of energy released during oxidative phosphorylation (OXPHOS) in living cells would advance the understanding of metabolic pathways and cell biology. However, the relationship between intracellular temperature and ATP fluctuation during the OXPHOS process is rarely studied due to the limitation of the sensing approach. Novel fluorescent polymer probes were developed for accurate simultaneous measurements of intracellular temperature and ATP. Utilizing the fluorescence imaging techniques, it was demonstrated for the first time that the temperature in mitochondria increased 2.4 degrees C and the ATP fluctuation level simultaneously decreased 75% within 2 min during the OXPHOS process. Moreover, the resultant fluorescent polymer probes had good performance and properties for mitochondrial targeting, providing an effective way for investigating mechanisms by which energy is released during the OXPHOS process. PMID- 30295465 TI - SET-LRP in Biphasic Mixtures of the Nondisproportionating Solvent Hexafluoroisopropanol with Water. AB - The fluorinated alcohol 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) is an especially effective solvent for solubilizing a wide range of polymers. However, the performance of HFIP as SET-LRP solvent has classically been questioned due to its poor Cu(I)X disproportionating properties. Taking advantage of the fast and quantitative disproportionation of Cu(I)X in water, SET-LRP in organic solvent/water mixtures rids the organic solvent of mediating this fundamental event. Here, the Cu(0) wire-catalyzed SET-LRP synthesis of well-defined poly(methyl acrylate)s and poly(butyl acrylate)s with narrow molecular weight distribution and near perfect bromine chain end functionality is reported in HFIP/water mixtures. The results reported here support the potential of HFIP/water mixtures in the preparation of more complex architectures including polymers with dual control over molecular weight and tacticity. Since HFIP is also a classic solvent for the denaturation of proteins this SET-LRP system is also expected to find applications in the grafting of protein. PMID- 30295466 TI - Glutaminase Affects the Transcriptional Activity of Peroxisome Proliferator Activated Receptor gamma (PPARgamma) via Direct Interaction. AB - Phosphate-activated glutaminases catalyze the deamidation of glutamine to glutamate and play key roles in several physiological and pathological processes. In humans, GLS encodes two multidomain splicing isoforms: KGA and GAC. In both isoforms, the canonical glutaminase domain is flanked by an N-terminal region that is folded into an EF-hand-like four-helix bundle. However, the splicing event replaces a well-structured three-repeat ankyrin domain in KGA with a shorter, unordered C-terminal stretch in GAC. The multidomain architecture, which contains putative protein-protein binding motifs, has led to speculation that glutaminases are involved in cellular processes other than glutamine metabolism; in fact, some proteins have been identified as binding partners of KGA and the isoforms of its paralogue gene, GLS2. Here, a yeast two-hybrid assay identified nuclear receptor peroxisome proliferator-activated receptor gamma (PPARgamma) as a new binding partner of the glutaminase. We show that KGA and GAC directly bind PPARgamma with a low-micromolar dissociation constant; the interaction involves the N-terminal and catalytic domains of glutaminases as well as the ligand binding domain of the nuclear receptor. The interaction occurs within the nucleus, and by sequestering PPARgamma from its responsive element DR1, the glutaminases decreased nuclear receptor activity as assessed by a luciferase reporter assay. Altogether, our findings reveal an unexpected glutaminase-binding partner and, for the first time, directly link mitochondrial glutaminases to an unanticipated role in gene regulation. PMID- 30295467 TI - Transition Metal Complexes and Photodynamic Therapy from a Tumor-Centered Approach: Challenges, Opportunities, and Highlights from the Development of TLD1433. AB - Transition metal complexes are of increasing interest as photosensitizers in photodynamic therapy (PDT) and, more recently, for photochemotherapy (PCT). In recent years, Ru(II) polypyridyl complexes have emerged as promising systems for both PDT and PCT. Their rich photochemical and photophysical properties derive from a variety of excited-state electronic configurations accessible with visible and near-infrared light, and these properties can be exploited for both energy- and electron-transfer processes that can yield highly potent oxygen-dependent and/or oxygen-independent photobiological activity. Selected examples highlight the use of rational design in coordination chemistry to control the lowest-energy triplet excited-state configurations for eliciting a particular type of photoreactivity for PDT and/or PCT effects. These principles are also discussed in the context of the development of TLD1433, the first Ru(II)-based photosensitizer for PDT to enter a human clinical trial. The design of TLD1433 arose from a tumor-centered approach, as part of a complete PDT package that includes the light component and the protocol for treating non-muscle invasive bladder cancer. Briefly, this review summarizes the challenges to bringing PDT into mainstream cancer therapy. It considers the chemical and photophysical solutions that transition metal complexes offer, and it puts into context the multidisciplinary effort needed to bring a new drug to clinical trial. PMID- 30295468 TI - N-type Bi-doped SnSe Thermoelectric Nanomaterials Synthesized by a Facile Solution Method. AB - An n-type Bi-doped SnSe was synthesized by a facile solution method followed by spark plasma sintering. We used bismuth(III) 2-ethyhexanoate as a cationic dopant precursor, which can absorb on the powder surface and then diffuse into the lattice to realize the substitution of Sn by Bi. A strip structure with low-angle boundary was constructed for effective phonon scattering. With increasing content of Bi, the carrier concentration decreased from 1.35 * 1019 cm-3 (p-type) in undoped SnSe to 4.7 * 1014 cm-3 (n-type) in Sn0.99Bi0.01Se and then increased to 1.3 * 1015 cm-3 (n-type) in Sn0.97Bi0.03Se. The Seebeck coefficient changed from positive to negative and presented n-type conducting behavior in the whole measured temperature range from 300 to 773 K, reaching a maximum absolute value of ~900 MUV K-1 at room temperature and ~300 MUV K-1 at 773 K. Considering the rich variety of metal 2-ethylhexanoates, higher thermoelectric performance is expected by different cationic doping in solution-synthesized nanomaterials. PMID- 30295469 TI - Horizontal and Vertical Distribution of Microplastics in Korean Coastal Waters. AB - This is the first survey to investigate the vertical distribution and composition of microplastics >20 MUm at the surface (0-0.2 m; bulk sample) and in the water column (3-58 m depth; pump) of six semi-enclosed bays and two nearshore areas of South Korea. The average microplastic abundance of 41 stations at all sampling depths was 871 particles/m3, and the microplastic abundance near urban areas (1051 particles/m3) was significantly higher than that near rural areas (560 particles/m3). Although the average microplastic abundances in the midcolumn (423 particles/m3) and bottom water (394 particles/m3) were approximately 4 times lower than that of surface water (1736 particles/m3), microplastics prevailed throughout the water column in concentrations of 10-2000 particles/m3. The average sizes of fragment and fiber type microplastics were 197 and 752 MUm, respectively. Although the polymer composition differed by depth depending on the particle size and density, polypropylene and polyethylene predominated throughout the water column regardless of their low density and particle size. Finally, the middle and bottom water samples contained higher abundances of microplastics than predicted by a model based on physical mixing, indicating that biological interactions also influence the downward movement of low-density microplastics. PMID- 30295470 TI - Mechanical-Tunable Capillary-Force-Driven Self-Assembled Hierarchical Structures on Soft Substrate. AB - Capillary-force-driven self-assembly (CFSA) has been combined with many top-down fabrication methods to be alternatives to conventional single micro/nano manufacturing techniques for constructing complicated micro/nanostructures. However, most CFSA structures are fabricated on a rigid substrate, and little attention is paid to the tuning of CFSA, which means that the pattern of structures cannot be regulated once they are manufactured. Here, by combining femtosecond laser direct writing with CFSA, a flexible method is proposed to fabricate self-assembled hierarchical structures on a soft substrate. Then, the tuning of the self-assembly process is realized with a mechanical-stretching strategy. With this method, different patterns of tunable self-assembled structures are obtained before tuning and after release, which is difficult to achieve with other techniques. In addition, as a proof-of-concept application, this mechanical tunable self-assembly of microstructures on a soft substrate is used for smart displays and versatile micro-object trapping. PMID- 30295471 TI - Polybrominated Diphenyl Ethers Quinone Induced Parthanatos-like Cell Death through a Reactive Oxygen Species-Associated Poly(ADP-ribose) Polymerase 1 Signaling. AB - Polybrominated diphenyl ethers (PBDEs) are emerging organic environmental pollutants, which were accused of various toxic effects. Here, we studied the role of a potential PBDEs quinone metabolite, PBDEQ, on cytotoxicity, oxidative DNA damage, and the alterations of signal cascade in HeLa cells. PBDEQ exposure leads to reactive oxygen species (ROS) accumulation, mitochondrial membrane potential (MMP) loss, lactate dehydrogenase (LDH) release, increasing terminal transferase-mediated dUTP-biotin nick end labeling (TUNEL) positive foci, and the elevation of apoptosis rate. Furthermore, we showed PBDEQ exposure result in increased DNA migration, micronucleus frequency, and the promotion of 8-OHdG and phosphorylation of histone H2AX (gamma-H2AX) levels. Mechanism study indicated that PBDEQ caused poly(ADP-ribose) polymerase 1 (PARP-1) activation and apoptosis inducing factor (AIF) nuclear translocation. All together, these results confirmed the occurrence of parthanatos-like cell death upon PBDEQ exposure. PMID- 30295472 TI - Site-Selective Cross-Coupling of Remote Chlorides Enabled by Electrostatically Directed Palladium Catalysis. AB - Control of site-selectivity in chemical reactions that occur remote from existing functionality remains a major challenge in synthetic chemistry. We describe a strategy that enables three of the most commonly used cross-coupling processes to occur with high site-selectivity on dichloroarenes that bear acidic functional groups. We have achieved this by repurposing an established sulfonylated phosphine ligand to exploit its inherent bifunctionality. Mechanistic studies suggest that the sulfonate group engages in attractive electrostatic interactions with the cation associated with the deprotonated substrate, guiding cross coupling to the chloride at the arene meta position. This counterintuitive combination of anionic ligand and anionic substrate demonstrates an alternative design principle when considering the application of noncovalent interactions to direct catalysis. PMID- 30295473 TI - Hybrid Metal-Organic-Framework/Inorganic Nanocatalyst toward Highly Efficient Discoloration of Organic Dyes in Aqueous Medium. AB - Nanoscale metal-organic frameworks (NMOFs) represent a unique class of solids with superior adsorption, mass transport, and catalytic properties. In this study, a facile and novel approach was developed for the generation of hybrid Cu NMOF/Ce-doped-Mg-Al-LDH nanocatalyst through in situ self-assembly and solvothermal synthesis of a 2D Cu-NMOF, [Cu2(MU-OH)(MU4-btc)(phen)2] n.5 nH2O {H3btc, trimesic acid; phen, 1,10-phenanthroline}, on a cerium-doped Mg-Al layered double hydroxide (Ce-doped-Mg-Al-LDH) matrix. Self-assembly between Cu NMOF nanocrystals and exfoliated LDH led to their nanoscale mixing and prevented the formation of aggregated Cu-NMOF nanoparticles. In the resulting hybrid nanostructure, Cu-NMOF nanocrystals (~10-20 nm particle size) are anchored uniformly on a Ce-doped-Mg-Al-LDH's surface, possessing a dimension of several hundred nanometers. Catalytic activity of Cu-NMOF/Ce-doped-Mg-Al-LDH and Cu-NMOF was evaluated under ambient conditions in the reductive degradation (discoloration) of aqueous solutions of 4-nitrophenol (4-NP, model substrate) and a series of commercial organic dyes by applying sodium borohydride as a reducing agent. The Cu-NMOF/Ce-doped-Mg-Al-LDH nanocatalyst exhibited an outstanding catalytic activity toward degradation of 4-NP, with kapp (rate constant) of 0.03 and a catalyst TOF (turnover frequency) up to 7.1 * 103 h-1. Full and very quick discoloration of organic dyes {rhodamine B (RhB), methylene blue (MB), Congo red (CR), methyl orange (MO), and rhodamine 6G (R6G)} was also achieved with TOF values of up to 1.4 * 105/h. A superior activity of the hybrid nanocatalyst over Cu-NMOF can be regarded as a synergic effect among Cu-NMOF and Ce-doped-Mg-Al-LDH components, while the Ce-doped-Mg-Al-LDH carrier acts as a cocatalyst. The hybrid nanocatalyst can easily be recovered and reused successfully for the five consecutive reaction runs with the same catalytic performance. This study also shows that NMOFs can be easily incorporated onto conventional catalyst supports, resulting in hybrid nanocatalysts with a highly uniform structural architecture, controlled chemical composition, and excellent catalytic function. PMID- 30295475 TI - Atmospheric Solid Analysis Probe and Modified Desorption Electrospray Ionization Mass Spectrometry for Rapid Screening and Semi-Quantification of Zilpaterol in Urine and Tissues of Sheep. AB - Ambient ionization mass spectrometric methods including desorption electrospray ionization (DESI) and atmospheric solid analysis probe (ASAP) have great potential for applications requiring real-time screening of target molecules in complex matrixes. Such techniques can also rapidly produce repeatable semiquantitative data, with minimal sample preparation, relative to liquid chromatography-mass spectrometry (LC-MS). In this study, a commercial ASAP probe was used to conduct both ASAP-MS and modified DESI (MDESI) MS analyses. We conducted real-time qualitative and semiquantitative analysis of the leanness enhancing agent zilpaterol in incurred sheep urine, kidney, muscle, liver, and lung samples using ASAP-MS and MDESI MS. Using ASAP, limits of detection (LOD) and quantitation (LOQ) in urine were 1.1 and 3.7 ng/mL, respectively, while for MDESI MS they were 1.3 and 4.4 ng/mL, respectively. The LODs for tissues were 0.1 0.4 ng/g using ASAP, and 0.2-0.6 ng/g with MDESI MS. The LOQs of the tissues in ASAP were 0.4-1.2 ng/g and 0.5-2.1 ng/g in MDESI MS. Trace levels of zilpaterol were accurately analyzed in urine and tissues of sheep treated with dietary zilpaterol HCl. The correlation coefficient ( R2) between semiquantitative ASAP MS and MDESI MS results of urine samples was 0.872. The data from ASAP and MDESI MS were validated using LC-MS/MS; urinary zilpaterol concentrations >=5.0 ng/mL or tissue zilpaterol concentrations >=1.5 ng/g were detected by ASAP and MDESI MS, respectively, 100% of the time. Forty samples could be analyzed in triplicate, directly from biological matrixes in under an hour. PMID- 30295474 TI - Mechanistic Insight on the Formation of GaN:ZnO Solid Solution from Zn-Ga Layered Double Hydroxide Using Urea as the Nitriding Agent. AB - A solid solution of GaN and ZnO (GaN:ZnO) is promising as a photocatalyst for visible-light-driven overall water splitting to produce H2. However, several obstacles still exist in the conventional preparation procedure of GaN:ZnO. For example, the atomic distributions of Zn and Ga are nonuniform in GaN:ZnO when a mixture of the metal oxides, i.e. Ga2O3 and ZnO, is used as a precursor. In addition, GaN:ZnO is generally prepared under a harmful NH3 flow for long durations at high temperatures. Here, a facile synthesis of GaN:ZnO with homogeneous atomic composition via a simple and safe procedure is reported. A layered double hydroxide (LDH) containing Zn2+ and Ga3+ was used to increase the uniformity of the atomic distributions of Zn and Ga in GaN:ZnO. We employed urea as a nitriding agent instead of gaseous NH3 to increase the safety of the reaction. Through the optimization of reaction conditions such as heat treatment temperature and content of urea, single-phase GaN:ZnO was successfully obtained. In addition, the nitridation mechanism using urea was investigated in detail. NH3 released from the thermal decomposition of urea did not directly nitride the LDH precursor. X-ray absorption and infrared spectroscopies revealed that Zn(CN2) like intermediate species were generated at the middle temperature range and Ga-N bonds formed at high temperature along with dissociation of CO and CO2. PMID- 30295477 TI - Nitro-Group-Containing Drugs. AB - The nitro group is considered to be a versatile and unique functional group in medicinal chemistry. Despite a long history of use in therapeutics, the nitro group has toxicity issues and is often categorized as a structural alert or a toxicophore, and evidence related to drugs containing nitro groups is rather contradictory. In general, drugs containing nitro groups have been extensively associated with mutagenicity and genotoxicity. In this context, efforts toward the structure-mutagenicity or structure-genotoxicity relationships have been undertaken. The current Perspective covers various aspects of agents that contain nitro groups, their bioreductive activation mechanisms, their toxicities, and approaches to combat their toxicity issues. In addition, recent advances in the field of anticancer, antitubercular and antiparasitic agents containing nitro groups, along with a patent survey on hypoxia-activated prodrugs containing nitro groups, are also covered. PMID- 30295476 TI - Mechanism of Permanganate-Promoted Dihydroxylation of Complex Diketopiperazines: Critical Roles of Counter-cation and Ion-Pairing. AB - The mechanism of permanganate-mediated dual C-H oxidation of complex diketopiperazines has been examined with density functional theory computations. The products of these oxidations are enabling intermediates in the synthesis of structurally diverse ETP natural products. We evaluated, for the first time, the impact of ion-pairing and aggregation states of the permanganate ion and counter cations, such as bis(pyridine)-silver(I) (Ag+) and tetra- n-butylammonium (TBA+), on the C-H oxidation mechanism. The C-H abstraction occurs through an open shell singlet species, as noted previously, followed by O-rebound and a competing OH rebound pathway. The second C-H oxidation proceeds with a second equivalent of oxidant with lower free energy barriers than the first C-H oxidation due to directing effects and the generation of a more reactive oxidant species after the first C-H oxidation. The success and efficiency of the second C-H oxidation are found to be critically dependent on the presence of an ion-paired oxidant. We used the developed mechanistic knowledge to rationalize an experimentally observed oxidation pattern for C3-indole-substituted diketopiperazine (+)-5 under optimal oxidation conditions: namely, the formation of diol (-)-6 as a single diastereomer and lack of the ketone products. We proposed two factors that may impede the ketone formation: (i) the conformational flexibility of the diketopiperazine ring, and (ii) hindrance of this site, making it less accessible to the ion-paired oxidant species.

Various 2 aminochalcones could be applied to this protocol, and the desired 2-substituted quinoline products were isolated in excellent yields by simple filtration. Furthermore, we elucidated the role of benzylamine in this transformation and provided the detailed reaction mechanism. This protocol has several additional advantages, such as simple operation, broad substrate scope, good functional group tolerance, easy product isolation, recycling of the catalyst, and gram scale synthesis.

AB - A series of Wrightia hanleyi extracts was screened for activity against Mycobacterium tuberculosis H37Rv. One active fraction contained a compound that initially appeared to be either the isoflavonoid wrightiadione or the alkaloid tryptanthrin, both of which have been previously reported in other Wrightia species. Characterization by NMR and MS, as well as evaluation of the literature describing these compounds, led to the conclusion that wrightiadione (1) was misidentified in the first report of its isolation from W. tomentosa in 1992 and again in 2015 when reported in W. pubescens and W. religiosa. Instead, the molecule described in these reports and in the present work is almost certainly the isobaric (same nominal mass) and isosteric (same number of atoms, valency, and shape) tryptanthrin (2), a well-known quinazolinone alkaloid found in a variety of plants including Wrightia species. Tryptanthrin (2) is also accessible synthetically via several routes and has been thoroughly characterized. Wrightiadione (1) has been synthesized and characterized and may have useful biological activity; however, this compound can no longer be said to be known to exist in Nature. To our knowledge, this misidentification of wrightiadione (1) has heretofore been unrecognized.

AB - The structure of the known Penicillium aurantiogriseum-derived secondary metabolite auranthine was refined using a combination of synthetic, spectroscopic, and X-ray diffractometric approaches. Thus, auranthine was shown to be a fused quinazolino benzodiazepinedione (2) bearing an acyclic aliphatic nitrile moiety, thereby significantly differing from the originally proposed structure 1 published in 1986. Its absolute configuration was confirmed by CD spectroscopy and DFT calculations. The cultivation of P. aurantiogriseum was optimized, allowing high production of auranthine. The cytotoxicity profile of auranthine and its semisynthetic analogues is reported. The refined structure of auranthine provides a valid target for the total synthesis of this underexplored natural product and its derivatives. PMID- 30295482 TI - Kaempferol Binding to Zinc(II), Efficient Radical Scavenging through Increased Phenol Acidity. AB - Zinc(II) enhances radical scavenging of the flavonoid kaempferol (Kaem) most significantly for the 1:1 Zn(II)-Kaem complex in equilibrium with the 1:2 Zn(II) Kaem complex both with high affinity at 3-hydroxyl and 4-carboxyl coordination. In methanol/chloroform (7/3, v/v), 1:1 Zn(II)-Kaem complex reduces beta-carotene radical cation, beta-Car*+, with a second-order rate constant, 1.88 * 108 L.mol 1.s-1, while both Kaem and 1:2 Zn(II)-Kaem complex are nonreactive, as determined by laser flash photolysis. In ethanol, 1:1 Zn(II)-Kaem complex reduces the 2,2 diphenyl-1-picrylhydrazyl radical, DPPH*, with a second-order rate constant, 2.48 * 104 L.mol-1.s-1, 16 times and 2 times as efficient as Kaem and 1:2 Zn(II)-Kaem complex, respectively, as determined by stopped-flow spectroscopy. Density functional theory calculation results indicate significantly increased acidity of Kaem as ligand in 1:1 Zn(II)-Kaem complex other than in 1:2 Zn(II)-Kaem complex. Kaem in 1:1 Zn(II)-Kaem complex loses two protons (one from 3-hydroxyl and one from phenolic hydroxyl) forming 1:1 Zn(II)-(Kaem-2H) during binding with Zn(II), while Kaem in 1:2 Zn(II)-Kaem complex loses one proton in each ligand forming Zn(II)-(Kaem-H)2, as confirmed by UV-vis absorption spectroscopy. Zn(II)-(Kaem 2H) is a far stronger reductant than Kaem and Zn(II)-(Kaem-H)2 as determined by cyclic voltammetry. Significant rate increases for the 1:1 complex in both beta Car*+ scavenging by electron transfer and DPPH* scavenging by hydrogen atom transfer were ascribed to decreases of ionization potential and of bond dissociation energy of 4'-OH for deprotonated Zn(II)-(Kaem-2H), respectively. Increased phenol acidity of plant polyphenols by 1:1 coordination with Zn(II) may explain the unique function of Zn(II) as a biological antioxidant and may help to design nontoxic metal-based drugs derived from natural bioactive molecules. PMID- 30295483 TI - Phospholipid-Cellulose Interactions: Insight from Atomistic Computer Simulations for Understanding the Impact of Cellulose-Based Materials on Plasma Membranes. AB - Cellulose is an important biocompatible and nontoxic polymer widely used in numerous biomedical applications. The impact of cellulose-based materials on cells and, more specifically, on plasma membranes that surround cells, however, remains poorly understood. To this end, here, we performed atomic-scale molecular dynamics simulations of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) bilayers interacting with the surface of a cellulose crystal. Both biased umbrella sampling and unbiased simulations clearly show the existence of strong attractive interactions between phospholipids and cellulose: the free energy of the cellulose-bilayer binding was found to be -1.89 and -1.96 kJ/mol per cellulose dimer for PC and PE bilayers, respectively. Although the values are similar, there is a pronounced difference between PC and PE bilayers. The driving force in both cases is the formation of hydrogen bonds. There are two distinct types of hydrogen bonds: (1) between the lipid head groups and the hydroxyl (hydroxymethyl) groups of cellulose, and (2) lipid-water and cellulose-water bonds. The former is the dominant component for PE systems whereas the latter dominates in PC systems. This suggests that achieving controlled binding via new cellulose modifications must pay close attention to the lipid head groups involved. The observed attractive phospholipid-cellulose interactions have a significant effect on bilayer properties: a cellulose crystal induces noticeable structural perturbations on the bilayer leaflet next to the crystal. Given that such perturbations can be undesirable when it comes to the interactions of cellulose-based materials with cell membranes, our computational studies suggest that the impact of cellulose could be reduced through chemical modification of the cellulose surface which prevents cellulose-phospholipid hydrogen bonding.

AB - A scalable and practical synthesis of functionalized indoles via Pd- tBuONO cocatalyzed aerobic cycloisomerization of o-allylanilines is reported. Using molecular oxygen as a terminal oxidant, a series of substituted indoles were prepared in moderate to good yields. The avoidance of hazardous oxidants, heavy metal cocatalysts, and high boiling point solvents such as DMF and DMSO enables this method to be applied in pharmaceutical synthesis. A practical gram-scale synthesis of indomethacin demonstrates its application potential. PMID- 30295486 TI - Direct Experimental Characterization of Contributions from Self-Motion of Hydrogen and from Interatomic Motion of Heavy Atoms to Protein Anharmonicity. AB - One fundamental challenge in biophysics is to understand the connection between protein dynamics and its function. Part of the difficulty arises from the fact that proteins often present local atomic motions and collective dynamics on the same time scales, and challenge the experimental identification and quantification of different dynamic modes. Here, by taking lyophilized proteins as the example, we combined deuteration technique and neutron scattering to separate and characterize the self-motion of hydrogen and the collective interatomic motion of heavy atoms (C, O, N) in proteins on the pico-to-nanosecond time scales. We found that hydrogen atoms present an instrument-resolution dependent onset for anharmonic motions, which can be ascribed to the thermal activation of local side-group motions. However, the protein heavy atoms exhibit an instrument-resolution-independent anharmonicity around 200 K, which results from unfreezing of the relaxation of the protein structures on the laboratory equilibrium time (100-1000 s), softening of the entire bio-macromolecules.

AB - The microsolvation and photophysics of 3-amino-1,2,4-triazole (3AT) after excitation to the light-absorbing S2(npi*) state were studied by using resonance Raman spectroscopy and single component artificial force-induced reaction (SC AFIR) in a global reaction route mapping (GRRM) strategy. The vibrational spectra were assigned on the basis of experimental data and density functional theory (DFT) calculations. The resonance Raman spectra of 3AT were measured to probe the excited state structural dynamics in the Franck-Condon region. The conformations of 3AT(CH3CN)1, 3AT(CH3OH)2, and 3AT(H2O)2 clusters were determined by combining vibrational spectrum experiments and B3LYP/6-311++G(d,p) computations. DFT calculations were carried out to obtain the minimal excitation energies of the lower-lying singlet excited states, and the curve-crossing points. It was revealed that the short-time structural dynamics of 3AT were dominated by the N-N stretching coordinates. An excited state decay mechanism is proposed: 3AT is initially excited to the S2(npi*) state, then the conical intersection (CI) of the S2(npi*)/S1(pipi*) potential energy surfaces is crossed, and 3AT then decays to the lower solvent-dependent excited state S1(pipi*). It subsequently returns to the S0 state, accompanied by a large Stokes fluorescence shift, which was interpreted as the stabilized S1(pipi*) excited state bonding to several water molecules via intermolecular hydrogen bonding.

AB - Ligand-based fluorine NMR screening has gained popularity in drug discovery projects during the past decade and has become a powerful methodology to produce high quality hits. Its high sensitivity to protein binding makes it particularly suitable for fragment screening, allowing detection and binding strength measurement of very weak affinity ligands. The screening can be performed in direct or competition format, and its versatility allows application to complex biological and chemical systems. As the potential of the methodology has now been recognized and successfully demonstrated in several relevant medicinal chemistry projects, it is now an appropriate time to report the learned lessons and point the way to the future. In this Perspective the principles of the methodology along with several applications to pharmaceutical projects are presented.

AB - A stereoselective protection-free asymmetric total synthesis of (+)-chamuvarinin (1), a potent anticancer and antitrypanosomal agent, has been accomplished. The adjacently linked [bis(tetrahydrofuran)]tetrahydropyran (THF-THF-THP) core of this natural product with seven stereogenic centers was constructed in a completely substrate-controlled fashion. The inter-ring stereochemistry ( threo,threo,threo) of the oxatricyclic core was established in a stereoselective fashion by a chelation-controlled Keck allylation, whereas the intraring cis or trans relative stereochemistry was controlled by a stereoselective internal alkylation. PMID- 30295490 TI - Incorporating In-Source Fragment Information Improves Metabolite Identification Accuracy in Untargeted LC-MS Data Sets. AB - In-source fragmentation occurs as a byproduct of electrospray ionization. We find that ions produced as a result of in-source fragmentation often match fragment ions produced during MS/MS fragmentation, and we take advantage of this phenomenon in a novel algorithm to analyze LC-MS metabolomics data sets. Our approach organizes coeluting MS1 features into a single peak group and then identifies in-source fragments among coeluting features using MS/MS spectral libraries. We tested our approach using previously published data of verified metabolites and compared the results to features detected by other mainstream metabolomics tools. Our results indicate that considering in-source fragment information as a part of the identification process increases the annotation quality, allowing us to leverage MS/MS data in spectrum libraries even if MS/MS scans were not collected.

AB - Nanotheranostics, combing diagnostic and therapeutic components in an all-in-one nanomaterial, possess exciting potentials for precision nanomedicine. However, a major obstacle for current nanotheranostics to enter preclinical and/or clinical trials is the intrinsic toxicities of these nanomaterials. As an emerging biomaterial, the bioinspired DNA nanostructure shows advantages for constructing better nanotheranostics due to its excellent features, including native biocompatibility, full programmability, and ready accessibility. In this feature article, we highlight recent advances in the design of DNA-nanostructure-based diagnostics and/or therapeutics capable of specifically responding to biological stimuli in a dynamic way, with a particular focus on the design mechanism, responsive performance, and potential for preclinical and/or clinical trials in personalized theranostics. PMID- 30295488 TI - Chemical Exchange Reaction Effect on Polarization Transfer Efficiency in SLIC SABRE. AB - Signal Amplification By Reversible Exchange (SABRE) is a new and rapidly developing hyperpolarization technique. The recent discovery of Spin-Lock Induced Crossing SABRE (SLIC-SABRE) showed that high field hyperpolarization transfer techniques developed so far were optimized for singlet spin order that does not coincide with the experimentally produced spin state. Here, we investigated the SLIC-SABRE approach and the most advanced quantitative theoretical SABRE model to date. Our goal is to achieve the highest possible polarization with SLIC-SABRE at high field using the standard SABRE system, IrIMes catalyst with pyridine. We demonstrated the accuracy of the SABRE model describing the effects of various physical parameters such as the amplitude and frequency of the radio frequency field, and the effects of chemical parameters such as the exchange rate constants. By fitting the model to the experimental data, the effective life time of the SABRE complex was estimated, as well as the entropy and enthalpy of the complex-dissociation reaction. We show, for the first time, that this SLIC-SABRE model can be useful for the evaluation of the chemical exchange parameters that are very important for the production of highly polarized contrast agents via SABRE.

A new chiral spiro-bisoxazoline ligand has proven to be an optimal ligand for the asymmetric reaction to give versatile chiral alpha silyl esters in good yields with high enantioselectivities. The mechanism and detailed stereochemical models for enantioselective induction were elucidated by DFT calculations, suggesting that the reaction proceeds via a concerted quintet transition state.

PMID- 30295499 TI - Creation of Magnetic Skyrmion Bubble Lattices by Ultrafast Laser in Ultrathin Films. AB - Magnetic skyrmions are topologically nontrivial spin textures which hold great promise as stable information carriers in spintronic devices at the nanoscale. One of the major challenges for developing novel skyrmion-based memory and logic devices is fast and controlled creation of magnetic skyrmions at ambient conditions. Here we demonstrate controlled generation of skyrmion bubbles and skyrmion bubble lattices from a ferromagnetic state in sputtered ultrathin magnetic films at room temperature by a single ultrafast (35 fs) laser pulse. The skyrmion bubble density increases with the laser fluence, and it finally becomes saturated, forming disordered hexagonal lattices. Moreover, we present that the skyrmion bubble lattice configuration leads to enhanced topological stability as compared to isolated skyrmions, suggesting its promising use in data storage. Our findings shed light on the optical approach to the skyrmion bubble lattice in commonly accessible materials, paving the road toward the emerging skyrmion-based memory and synaptic devices. PMID- 30295500 TI - Analysis of Adsorbed Layers of Benzyldimethyldodecylammonium Bromide on Silica Particles in Water Using the Sorbent Mass Variation Method. AB - A "sorbent mass variation" (SMV) method has been suggested to investigate the adsorption at solid-liquid interfaces, which can provide information on the adsorbed layer structure including its thickness and composition. However, there has been little research focused on the method, and therefore, it is essential to examine its general applicability. Herein, the adsorption of benzyldimethyldodecylammonium bromide (BDDABr), a cationic surfactant, on silica (SiO2) nanoparticles (with ~12 and 24 nm in size, denoted as S-SiO2 and L-SiO2, respectively) in water was investigated using the SMV method. The adsorption isotherms all show a linearly declining tendency in the saturated adsorption regime, consistent with the prediction of the SMV model. The adsorption is interpreted to form noncomplete bilayers (or isolated admicelles). The thicknesses of the adsorbed bilayers on S-SiO2 and L-SiO2 are estimated to be ~2.9 and 2.7 nm, respectively, and the volume fractions of BDDABr in the saturated adsorbed layers are 0.63 and 0.68, respectively. In addition, the change in the Gibbs free energy of the adsorption process is also analyzed, showing its spontaneous nature. This work demonstrates that the SMV method is available for investigation on the adsorption of surfactants at solid-liquid interfaces, which can provide information on the structure and formation thermodynamics of adsorbed layers. PMID- 30295501 TI - Clinical significance of antibodies to antigens in the Raph, John Milton Hagen, I, Globoside, Gill, Rh-associated glycoprotein, FORS, JR, LAN, Vel, CD59, and Augustine blood group systems. AB - CONCLUSIONS: This article reviews information on the clinical significance of antibodies to antigens in the Raph, John Milton Hagen, I, Globoside, Gill, Rh associated glycoprotein, FORS, JR, LAN, Vel, CD59, and Augustine blood group systems. Antibodies to many of the antigens in these groups are rarely encountered because of the high prevalence of the associated antigens in most populations. For many of these antibodies, the clinical significance-that is, the potential to cause reduced survival of transfused antigen-positive red blood cells or a transfusion reaction (e.g., anti-P, anti-Jra, and anti-Lan), and/or hemolytic disease of the fetus and newborn (e.g., anti-RHAG4 and anti-Vel)-has been documented. For other antibodies, their prevalence is so rare that information on the clinical significance of their antibodies is not available (e.g., anti-FORS1). PMID- 30295502 TI - Rouleaux and saline replacement. AB - CONCLUSIONS: Rouleaux is a phenomenon that commonly occurs in patients who have an increased number of circulating protein macromolecules. It is a benign, in vitro reaction that appears microscopically as red blood cells (RBCs) line up against each other; many liken the RBC aggregation to "stacked coins." This unexpected reactivity may cause confusion in direct agglutination testing such as reverse blood typing and crossmatching. Saline replacement is the established method to resolve rouleaux. True agglutination will remain when plasma is replaced with saline for resuspension of the RBC button. Rouleaux will no longer be seen when the plasma proteins are removed. PMID- 30295503 TI - Method-specific and unexplained reactivity in automated solid-phase testing and their association with specific antibodies. AB - CONCLUSIONS: The inherent tradeoff between sensitivity and specificity in the detection of unexplained antibodies has been the objective of many studies, editorials, and journal articles. Many publications note that no method is capable of detecting all clinically significant antibodies while avoiding all clinically insignificant antibodies. This study describes the frequency of nonspecific reactivity and unexplained reactivity in solid-phase testing, along with the subsequent development of specific antibodies (Abs). In this study, nonspecific reactivity (NS) is defined as method-specific panreactivity detected by solid-phase testing only, with no reactivity in other methods. Unexplained reactivity (UR) is defined as reactivity present and detectable in all test methods after all clinically significant antibodies were ruled out following a standard antibody identification algorithm using selected cell panels. This retrospective study evaluated antibody detection tests of patients at a single center for 2 years using two automated solid-phase instruments that used the same three-cell antibody detection test. Antibody identification was performed with solid-phase panels supplemented with a polyethylene glycol tube method as needed. Of the 1934 (5%) samples with a positive antibody detection test, 29 had unavailable work-up data, leaving 1905 (98.5%) samples eligible for inclusion in the study. The data revealed the following: Ab only 999 (52.4%); UR only 429 (22.5%); Ab and UR 227 (11.9%); NS only 206 (10.8%); Ab and NS 24 (1.3%); UR and NS 14 (0.7%); and Ab, UR, and NS 6 (0.3%). Patients with a positive follow-up antibody detection test had UR and NS replaced with a specific Ab in 23 of 656 UR (3%) and 8 of 230 NS (3%) cases, respectively. Additionally, six patients with UR developed a specific Ab along with persistent UR, and no patients with persistent NS developed a specific Ab. The study concluded that both UR and NS can be encountered in solid-phase testing, and both UR and NS can persist in follow-up testing. Specific Ab was observed to replace UR in a few patients. PMID- 30295504 TI - Utility of chloroquine diphosphate in the blood bank laboratory. AB - CONCLUSIONS: Chloroquine diphosphate (CDP) is a helpful tool in the blood bank for two main applications. The most common application is to render direct antiglobulin test-positive red blood cells (RBCs) free from membrane-bound IgG; these treated RBCs can then be used for autologous adsorption and/or to determine the patient's RBC phenotype. Another common use of CDP is to remove human leukocyte antigens (HLAs) from RBCs to help identify or exclude the presence of antibodies to HLAs expressed on RBCs, for example, Bennett-Goodspeed (Bg) antigens. In this review, the principles, applications, and limitations of using CDP are discussed. PMID- 30295505 TI - Clinical significance of antibodies to antigens in the Scianna, Dombrock, Colton, Landsteiner-Weiner, Chido/Rodgers, H, Kx, Cromer, Gerbich, Knops, Indian, and Ok blood group systems. AB - CONCLUSIONS: This article reviews information regarding the clinical significance of antibodies to antigens in the Scianna, Dombrock, Colton, Landsteiner-Wiener, Chido/Rodgers, H, Kx, Cromer, Gerbich, Knops, Indian, and Ok blood group systems. Like most blood group systems, antibodies to many of the antigens in these groups are rarely encountered because of the high prevalence of the associated antigens in most populations. For many, the clinical significance-that is, the potential to cause reduced survival of transfused antigen-positive red blood cells or a transfusion reaction (e.g., anti-Ge2, anti-H) and/or hemolytic disease of the fetus and newborn (e.g., anti-Coa, anti-Ge3)-has been documented. Some of these antibodies are not always clinically significant, and because of the high prevalence of the antigen, antigen-negative blood may be extremely difficult to find (e.g., anti-LW, anti-Inb). The use of a monocyte monolayer assay may be helpful when making transfusion decisions for patients with these antibodies. For others, their prevalence is so rare that information on the clinical significance of their antibodies is not available (e.g., anti-Co4, anti-Ok). PMID- 30295506 TI - A delayed and acute hemolytic transfusion reaction mediated by anti-c in a patient with variant RH alleles. AB - CONCLUSIONS: The Rh system is the most complex of the human blood groups. Of the 55 antigens that have been characterized, the system's principal antigens D, C, E, c, and e are responsible for the majority of clinically significant Rh antibodies. In the last few years, advancements in molecular testing have provided a wealth of information on the genetic diversity of the Rh locus. This case report describes a patient with variant RHD*DAR alleles inherited in conjunction with two compound heterozygote RHCE*ceEK/RHCE*ceAR alleles. The patient was previously alloimmunized to D, C, and E and possibly hrS. Further transfusion of D-C-E-K- RBCs resulted in a suspected acute hemolytic transfusion reaction and the subsequent identification of anti-c. Monocyte monolayer assay testing suggests clinical significance with a range of 29.5-38.5 percent reactive monocytes. PMID- 30295507 TI - Detecting polyagglutinable red blood cells. AB - CONCLUSIONS: Polyagglutination is a condition in which red blood cells (RBCs) are agglutinated by normal adult human sera but not by autologous or newborn sera. Polyagglutination is caused by changes in the RBC membrane that enable patient RBCs to agglutinate with normal human sera; this agglutination can interfere with blood bank testing. Depending on the cause, polyagglutination may or may not be the cause of RBC hemolysis. Lectins and human sera can be used to detect polyagglutinable RBCs. Identification of this phenomenon can be helpful in providing not only transfusion recommendation information for physicians but also information associated with pathogens (i.e., Streptococcus pneumoniae) and severity of illness. Testing with ABO group-compatible adult human sera can determine if a patient's RBCs are polyagglutinable. Further testing with a variey of lectins may identify the kind of polyagglutination. PMID- 30295508 TI - Case Studies of the Impacts of Cataract Surgery on Crested Penguin Welfare. AB - As nonhuman animals age, geriatric individuals require additional care and veterinary support to ensure their well being. The focus on lifelong care is a relatively newer approach when providing good welfare, and few studies have examined how veterinary care impacts behavior at different ages or how best to accommodate geriatric individuals in zoos. The objectives of this study were to (a) assess both the immediate and long-term (one year later) behavioral impacts of cataract removal for macaroni (Eudyptes chrysolophus) and southern rockhopper (Eudyptes chrysocome) penguins; (b) compare the behavior of penguins following cataract surgery to that of other conspecifics in the same habitat; and (c) monitor the impacts of cataract surgery on swimming behavior using time-depth recorders. Individual responses to cataract removal differed in direction and magnitude, and these mixed results highlight that welfare is experienced and thus measured at the individual level. Positive responses included increased habitat use, increased time spent swimming, and increased rates of affiliative interactions. This study highlights the importance of assessing welfare impacts of veterinary interventions on geriatric individuals. PMID- 30295509 TI - Effects of obesity on insulin: insulin-like growth factor 1 hybrid receptor expression and Akt phosphorylation in conduit and resistance arteries. AB - Insulin and insulin-like growth factor-1 stimulate specific responses in arteries, which may be disrupted by diet-induced obesity. We examined (1) temporal effects of high-fat diet compared to low-fat diet in mice on insulin receptor, insulin-like growth factor-1 receptor, insulin receptor/insulin-like growth factor-1 receptor hybrid receptor expression and insulin/insulin-like growth factor-1-mediated Akt phosphorylation in aorta; and (2) effects of high fat diet on insulin and insulin-like growth factor-1-mediated Akt phosphorylation and vascular tone in resistance arteries. Medium-term high-fat diet (5 weeks) decreased insulin-like growth factor-1 receptor expression and increased hybrid expression (~30%) only. After long-term (16 weeks) high-fat diet, insulin receptor expression was reduced by ~30%, insulin-like growth factor-1 receptor expression decreased a further ~40% and hybrid expression increased a further ~60%. Independent correlates of hybrid receptor expression were high-fat diet, duration of high-fat diet and plasma insulin-like growth factor-1 (all p < 0.05). In aorta, insulin was a more potent activator of Akt than insulin-like growth factor-1, whereas in resistance arteries, insulin-like growth factor-1 was more potent than insulin. High-fat diet blunted insulin-mediated vasorelaxation ( p < 0.01) but had no effect on insulin-like growth factor-1-mediated vasorelaxation in resistance arteries. Our findings support the possibility that hybrid receptor level is influenced by nutritional and metabolic cues. Moreover, vessel-dependent effects of insulin and insulin-like growth factor-1 on vascular tone and Akt activation may have implications in treating obesity-related vascular disease. PMID- 30295510 TI - Welfare of layers housed in small furnished cages on Danish commercial farms: the condition of keel bone, feet, plumage and skin. AB - 1. An on-farm assessment of keel bone, feet, plumage and skin damage was conducted in layers in small furnished cages to evaluate welfare implications. 2. Thirteen farms participated, all housing Lohmann LSL layers in systems allowing 8 or 10 hens per cage. 3. Each flock was visited at three different ages: 32, 62 and 77 weeks. During each visit, 100 hens were examined for keel bone fractures and deviations, plumage damage, body wounds, foot pad lesions, bumble feet, missing toes and toe wounds. 4. A deterioration with age of the condition of the plumage and keel bone was found (P < 0.001). At 77 weeks of age, 16% of the birds had poor plumage, and 43% of the birds had keel bone damage. In contrast, foot pad lesions were most prevalent at 32 weeks of age (13%), whereas the other foot injuries and body wounds remained at a relatively low level throughout the three ages examined. 5. Prevention of damage to the keel bone, plumage and foot pads should therefore be considered when aiming to improve welfare of laying hens housed in small furnished cages. PMID- 30295512 TI - A readily available improvement over method of moments for intra-cluster correlation estimation in the context of cluster randomized trials and fitting a GEE-type marginal model for binary outcomes. AB - Background/aims Cluster randomized trials are popular in health-related research due to the need or desire to randomize clusters of subjects to different trial arms as opposed to randomizing each subject individually. As outcomes from subjects within the same cluster tend to be more alike than outcomes from subjects within other clusters, an exchangeable correlation arises that is measured via the intra-cluster correlation coefficient. Intra-cluster correlation coefficient estimation is especially important due to the increasing awareness of the need to publish such values from studies in order to help guide the design of future cluster randomized trials. Therefore, numerous methods have been proposed to accurately estimate the intra-cluster correlation coefficient, with much attention given to binary outcomes. As marginal models are often of interest, we focus on intra-cluster correlation coefficient estimation in the context of fitting such a model with binary outcomes using generalized estimating equations. Traditionally, intra-cluster correlation coefficient estimation with generalized estimating equations has been based on the method of moments, although such estimators can be negatively biased. Furthermore, alternative estimators that work well, such as the analysis of variance estimator, are not as readily applicable in the context of practical data analyses with generalized estimating equations. Therefore, in this article we assess, in terms of bias, the readily available residual pseudo-likelihood approach to intra-cluster correlation coefficient estimation with the GLIMMIX procedure of SAS (SAS Institute, Cary, NC). Furthermore, we study a possible corresponding approach to confidence interval construction for the intra-cluster correlation coefficient. Methods We utilize a simulation study and application example to assess bias in intra cluster correlation coefficient estimates obtained from GLIMMIX using residual pseudo-likelihood. This estimator is contrasted with method of moments and analysis of variance estimators which are standards of comparison. The approach to confidence interval construction is assessed by examining coverage probabilities. Results Overall, the residual pseudo-likelihood estimator performs very well. It has considerably less bias than moment estimators, which are its competitor for general generalized estimating equation-based analyses, and therefore, it is a major improvement in practice. Furthermore, it works almost as well as analysis of variance estimators when they are applicable. Confidence intervals have near-nominal coverage when the intra-cluster correlation coefficient estimate has negligible bias. Conclusion Our results show that the residual pseudo-likelihood estimator is a good option for intra-cluster correlation coefficient estimation when conducting a generalized estimating equation-based analysis of binary outcome data arising from cluster randomized trials. The estimator is practical in that it is simply a result from fitting a marginal model with GLIMMIX, and a confidence interval can be easily obtained. An additional advantage is that, unlike most other options for performing generalized estimating equation-based analyses, GLIMMIX provides analysts the option to utilize small-sample adjustments that ensure valid inference. PMID- 30295513 TI - A rapid and scalable integrated membrane separation process for purification of polysaccharides from Enteromorpha prolifera. AB - An integrated membrane separation process combining the tubular ceramic microfiltration (MF) membrane and the flat-sheet ultrafiltration (UF) membrane was developed to purify polysaccharides from Enteromorpha prolifera. The effects of membrane pore size, molecular weight cut-off (MWCO), transmembrane pressure (TMP) and adding-water multiples on membrane performance were in-depth studied. The results indicated that the optimal membrane pore size and TMP of the tubular ceramic MF process were found to be 1.2 MUm and 0.225 MPa, and the optimal MWCO and TMP of the flat-sheet UF process were found to be 100 kDa and 0.3 MPa. The yields of polysaccharides were increased and optimized while the adding-water multiples was 1 during the diafiltration procedure. Furthermore, the water fluxes could be completely recovered using the specialized membrane cleaning methods, which ensured the reuse of membrane elements and satisfied the demands of industrial production. After purification by this integrated membrane separation process, the content of polysaccharides reached to 96.3%. The purified polysaccharides exhibited the superior moisture absorption and moisture retention properties compared to glycerol, polyethylene glycol (PEG) and luffa water.

(Asteraceae). Their chemical structures were verified using IR, UV, 2D and 1D NMR, and HRMS. Compounds 3-5 displayed potent lipoxygenase inhibitory potential with IC50s 2.26, 1.83, and 1.17 MUM, respectively compared to indomethacin (IC50 0.89 MUM). Moreover, molecular docking study revealed that the potent activity of 5 is due to H-bonding and hydrophobic interaction. The results of this study suggested that Tagetes minuta dietary consumption would be useful for the individuals at risk of acute and chronic inflammatory disorders.

AB - This study aims to analyze the correlations and relevance of self-efficacy items in 411 patients with diabetes using network analysis. We found that the self efficacy items structure is consistent between genders and types of diabetes. However, the strength of item correlations was significantly higher in type 2 diabetes. The items central to the network were following a regular diet in type 2 diabetes and adjusting diet when ill in type 1 diabetes. No significant gender differences were found. Knowledge of the most central aspects of self-efficacy and their interconnections can help clinicians to target psychoeducational interventions aimed at empowering patients.

Thus, the present study examined various methodological approaches for improving these relationships. DESIGN: A total of 1679 participants (women = 943, men = 736, M age-39.8) were randomly drawn from the general Norwegian population (response rate 34%). This prospective cohort study included two follow-ups at 10 (n = 1181) and 23 months (n = 942). MAIN OUTCOME MEASURES: Satisfaction with life and absence of psychological distress (i.e. anxiety and depression) represented a joint measure for indexing 'mental wellness' (MW). RESULTS: A simple count of SLEs weakly predicted MW, as expected, whereas the addition of a moderator (i.e. manageability of the event) substantially improved predictive power. Four additional moderators were examined: duration, impact, help-seeking and time since onset, but these were non-significant after inserting manageability into the model. This SLE counting method also retained its predictive power after including multiple criterion-related variables that substantially adjusted the longitudinal statistical model. CONCLUSION: This new SLE counting method exhibited a considerable improvement to predicting mental health and well-being. It is well suited for use in epidemiological research requiring a short SLE checklist format with high predictive power.

AB - We designed and evaluated the efficacy of a computer-based cognitive training program (Executive Function Enhancement Program [EFEP]) to stimulate executive functions through enhancing planning in normally-developing children. A total of 111 Colombian children participated in the study. Fifty-nine (53%) of the children were assigned to the experimental condition (application of the EFEP program) with two levels of planning performance, and fifty-two (47%) to the waiting list control condition with the same two levels of planning. The training program was applied three times a week over six weeks, with post-intervention assessment two weeks after the end of training. A follow-up assessment was carried out three months later. Results showed that the intervention program was particularly effective in the children with lower pre-intervention performance in planning, demonstrating that the program is an efficient therapeutic instrument for enhancing the executive function of planning in children between 5 and 7 years old. PMID- 30295517 TI - Neuropsychological assessment of Chilean children with a history of extreme prematurity: An exploratory study. AB - This study was conducted to explore the neuropsychological abilities of premature Chilean children. Two groups (Premature and Control, 10 children each, age ranging from 5 to 7.11) were established based on weeks of gestation and/or weight at birth. Relevant variables such as age, gender, schooling, and socioeconomic level were matched considering Chile's particular demographic context. Children were assessed by means of the Evaluacion Neuropsicologica Infantil (ENI-2) battery, measuring nine cognitive domains encompassing 23 subscales. In turn, subscales are grouped in two scales: Cognitive Functions and Executive Functions. Since the ENI-2 battery provides norms for Spanish-speaking children, obtained data were inspected both for possible between-group differences and either adjustment or deviance from average range. Results show that premature children perform within typical ranges in all subscales except for Visual attention and Graphic fluency. When comparing both groups, some differences emerged. These differences are most prominent in subscales related to visuoperceptual skills. Interestingly, between-group linguistic performance is very similar. The point is made that early linguistic interventions conducted on premature children seem to positively impact on oral language expression and comprehension. On the contrary, early interventions focused on visuospatial abilities did not seem to attain the same impact. This may be a consequence of visual-information processing problems derived from cortical dorsal stream's vulnerability, which literature correlates with prematurity. PMID- 30295518 TI - Trends in the surgical treatment of pathological fractures of the long bones. AB - AIMS: The aim of this study was to assess the current trends in the estimation of survival and the preferred forms of treatment of pathological fractures among national and international general and oncological orthopaedic surgeons, and to explore whether improvements in the management of these patients could be identified in this way. MATERIALS AND METHODS: All members of the Dutch Orthopaedic Society (DOS) and the European Musculoskeletal Oncology Society (EMSOS) were invited to complete a web-based questionnaire containing 12 cases. RESULTS: A total of 96 of 948 members of the DOS (10.1%; groups 1 and 2) and 33 of 182 members of the EMSOS (18%; group 3) replied. The estimation of survival was accurate by more than 50% of all three groups, if the expected survival was short (< 3 months) or long (> 12 months). General orthopaedic surgeons preferred using an intramedullary nail for fractures of the humerus and femur, irrespective of the expected survival or the origin of primary tumour or the location of the fracture. Oncological orthopaedic surgeons recommended prosthetic reconstruction in patients with a long expected survival. CONCLUSION: Identifying patients who require centralized care, as opposed to those who can be adequately treated in a regional centre, can improve the management of patients with pathological fractures. This differentiation should be based on the expected survival, the type and extent of the tumour, and the location of the fracture. Cite this article: Bone Joint J 2018;100-B:1392-8. PMID- 30295519 TI - Predicted final spinal height in patients with adolescent idiopathic scoliosis can be achieved by surgery regardless of maturity status. AB - AIMS: The aim of this study was to investigate the impact of maturity status at the time of surgery on final spinal height in patients with an adolescent idiopathic scoliosis (AIS) using the spine-pelvic index (SPI). The SPI is a self control ratio that is independent of age and maturity status. PATIENTS AND METHODS: The study recruited 152 female patients with a Lenke 1 AIS. The additional inclusion criteria were a thoracic Cobb angle between 45 degrees and 70 degrees , Risser 0 to 1 or 3 to 4 at the time of surgery, and follow-up until 18 years of age or Risser stage 5. The patients were stratified into four groups: Risser 0 to 1 and selective fusion surgery (Group 1), Risser 0 to 1 and non selective fusion (Group 2), Risser 3 to 4 and selective fusion surgery (Group 3), and Risser 3 to 4 and non-selective fusion (Group 4). The height of spine at follow-up (HOSf) and height of pelvis at follow-up (HOPf) were measured and the predicted HOS (pHOS) was calculated as 2.22 (SPI) * HOPf. One-way analysis of variance (ANOVA) was performed for statistical analysis. RESULTS: Of the 152 patients, there were 32 patients in Group 1, 27 patients in Group 2, 48 patients in Group 3, and 45 patients in Group 4. Significantly greater HOSf was observed in Group 3 compared with Group 1 (p = 0.03) and in Group 4 compared with Group 2 (p = 0.02), with similar HOPf (p = 0.75 and p = 0.83, respectively), suggesting that patients who undergo surgery at Risser grade of 0 to 1 have a shorter spinal height at follow-up than those who have surgery at Risser 4 to 5. HOSf was similar to pHOS in both Group 1 and Group 2 (p = 0.62 and p = 0.45, respectively), indicating that undergoing surgery at Risser 0 to 1 does not necessarily affect final spinal height. CONCLUSION: This study shows that fusion surgery at Risser 0 may result in growth restriction unlike fusion surgery at Risser 3 to 4. Despite such growth restriction, AIS patients could reach their predicted or 'normal' spinal height after surgery regardless of baseline maturity status due to the longer baseline spinal length in AIS patients and the remaining growth potential at the non-fusion levels.

PMID- 30295521 TI - Comparison of molecular diagnosis with serum markers and synovial fluid analysis in patients with prosthetic joint infection. AB - AIMS: The aim of this study was to compare the results of 16S/28S rRNA sequencing with the erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, and synovial fluid analysis in the diagnosis of prosthetic joint infection (PJI). PATIENTS AND METHODS: Between September 2015 and August 2016, 214 consecutive patients were enrolled. In the study population, there were 25 patients with a PJI and 189 controls. Of the PJI patients, 14 (56%) were women, and the mean age at the time of diagnosis was 65 years (38 to 83). The ESR and CRP levels were measured, and synovial fluid specimens were collected prospectively. Synovial fluid was subjected to reverse transcription polymerase chain reaction (RT PCR)/sequence analysis targeting the 16S/28S rRNA, and to conventional culture. Laboratory personnel who were blind to the clinical information performed all tests. The diagnosis of PJI was based on the criteria of the Musculoskeletal Infection Society. RESULTS: A total of 25 patients had a confirmed PJI. In 20 cases of monomicrobial PJI, the PCR products could be perfectly matched with the 16S/28S rRNA genes specific for different species of bacteria provided by sequence analysis. Of the five polymicrobial cases of PJI, 16S/28S rRNA PCR sequence analysis failed to identify the concordant bacteria species. In the 189 control patients, there was one false-positive RT-PCR result. The sensitivity and specificity of the molecular diagnosis method were 100% (95% confidence interval (CI) 85.7 to 100) and 99.5% (95% CI 97.1 to 99.9), respectively, whereas the positive and negative predictive values of PCR were 96.1% (95% CI 79.6 to 99.9) and 100% (95% CI 98.1 to 100), respectively. The PCR results were significantly better than serological diagnostic methods (p = 0.004 and p = 0.010 for ESR and CRP, respectively), the synovial fluid white blood cell (WBC) count (p = 0.036), and percentage of polymorphonuclear cells (PMN%) (p = 0.014). CONCLUSION: Stepwise RT-PCR and sequence analysis of the 16S/28S rRNA carried out under stringent laboratory conditions achieved highly sensitive and specific results for the differentiation between aseptic and septic joints undergoing arthroplasty. Sequence analysis successfully identified bacterial strains in monomicrobial infections but failed to identify molecular targets in polymicrobial infections. Further refinement of the protocols to identify the bacteria in polymicrobial infections is needed. Cite this article: Bone Joint J 2018;100-B:1345-51. PMID- 30295522 TI - The cost-effectiveness of dual mobility in a spinal deformity population with high risk of dislocation. AB - AIMS: The routine use of dual-mobility (DM) acetabular components in total hip arthroplasty (THA) may not be cost-effective, but an increasing number of patients undergoing THA have a coexisting spinal disorder, which increases the risk of postoperative instability, and these patients may benefit from DM articulations. This study seeks to examine the cost-effectiveness of DM components as an alternative to standard articulations in these patients. PATIENTS AND METHODS: A decision analysis model was used to evaluate the cost effectiveness of using DM components in patients who would be at high risk for dislocation within one year of THA. Direct and indirect costs of dislocation, incremental costs of using DM components, quality-adjusted life-year (QALY) values, and the probabilities of dislocation were derived from published data. The incremental cost-effectiveness ratio (ICER) was established with a willingness-to-pay threshold of $100 000/QALY. Sensitivity analysis was used to examine the impact of variation. RESULTS: In the base case, patients with a spinal deformity were modelled to have an 8% probability of dislocation following primary THA based on published clinical ranges. Sensitivity analysis revealed that, at its current average price ($1000), DM is cost-effective if it reduces the probability of dislocation to 0.9%. The threshold cost at which DM ceased being cost-effective was $1180, while the ICER associated with a DM THA was $71 000 per QALY. CONCLUSION: These results indicate that under specific clinical and economic thresholds, DM components are a cost-effective form of treatment for patients with spinal deformity who are at high risk of dislocation after THA.

AB - Deep infection was identified as a serious complication in the earliest days of total hip arthroplasty. It was identified that airborne contamination in conventional operating theatres was the major contributing factor. As progress was made in improving the engineering of operating theatres, airborne contamination was reduced. Detailed studies were carried out relating airborne contamination to deep infection rates. In a trial conducted by the United Kingdom Medical Research Council (MRC), it was found that the use of ultra-clean air (UCA) operating theatres was associated with a significant reduction in deep infection rates. Deep infection rates were further reduced by the use of a body exhaust system. The MRC trial also included a detailed microbiology study, which confirmed the relationship between airborne contamination and deep infection rates. Recent observational evidence from joint registries has shown that in contemporary practice, infection rates remain a problem, and may be getting worse. Registry observations have also called into question the value of "laminar flow" operating theatres. Observational evidence from joint registries provides very limited evidence on the efficacy of UCA operating theatres. Although there have been some changes in surgical practice in recent years, the conclusions of the MRC trial remain valid, and the use of UCA is essential in preventing deep infection. There is evidence that if UCA operating theatres are not used correctly, they may have poor microbiological performance. Current UCA operating theatres have limitations, and further research is required to update them and improve their microbiological performance in contemporary practice.

AB - AIMS: The aim of this study was to determine the efficacy of repeat epidural steroid injections as a form of treatment for patients with insufficiently controlled or recurrent radicular pain due to a lumbar or cervical disc herniation. PATIENTS AND METHODS: A cohort of 102 patients was prospectively followed, after an epidural steroid injection for radicular symptoms due to lumbar disc herniation, in 57 patients, and cervical disc herniation, in 45 patients. Those patients with persistent pain who requested a second injection were prospectively followed for one year. Radicular and local pain were assessed on a visual analogue scale (VAS), functional outcome with the Oswestry Disability Index (ODI) or the Neck Pain and Disability Index (NPAD), as well as health related quality of life (HRQoL) using the 12-Item Short-Form Health Survey questionnaire (SF-12). RESULTS: A second injection was performed in 17 patients (29.8%) with lumbar herniation and seven (15.6%) with cervical herniation at a mean of 65.3 days (sd 46.5) and 47 days (sd 37.2), respectively, after the initial injection. All but one patient, who underwent lumbar microdiscectomy, responded satisfactorily with a mean VAS for leg pain of 8.8 mm (sd 10.3) and a mean VAS for arm pain of 6.3 mm (sd 9) one year after the second injection, respectively. Similarly, functional outcome and HRQoL were improved significantly from the baseline scores: mean ODI, 12.3 (sd 12.4; p < 0.001); mean NPAD, 19.3 (sd 24.3; p = 0.041); mean SF-12 physical component summary (PCS) in lumbar herniation, 46.8 (sd 7.7; p < 0.001); mean SF-12 PCS in cervical herniation, 43 (sd 6.8; p = 0.103). CONCLUSION: Repeat steroid injections are a justifiable form of treatment in symptomatic patients with lumbar or cervical disc herniation whose symptoms are not satisfactorily relieved after the first injection.

AB - AIMS: There are limited published data detailing the volumetric material loss from tapers of conventional metal-on-polyethylene (MoP) total hip arthroplasties (THAs). Our aim was to address this by comparing the taper wear rates measured in an explanted cohort of the widely used Exeter THA with those measured in a group of metal-on-metal (MoM) THAs. PATIENTS AND METHODS: We examined an existing retrieval database to identify all Exeter V40 and Universal MoP THAs. Volumetric wear analysis of the taper surfaces was conducted using previously validated methodology. These values were compared with those obtained from a series of MoM THAs using non-parametric statistical methodology. A number of patient and device variables were accounted for using multiple regression modelling. RESULTS: A total of 95 Exeter MoP and 249 MoM THAs were examined. The median volumetric loss from the MoM cohort was over four times larger than that from the MoP cohort (1.01 mm3 vs 0.23 mm3, p < 0.001), despite a significantly shorter median period in vivo for the MoM group (48 months vs 90 months, p < 0.001). Multiple regression modelling indicated that the dominant variables leading to greater female taper material loss were bearing diameter (p < 0.001), larger female taper angles (p < 0.001), and male titanium stem tapers (p < 0.001). CONCLUSION: Consistent with the long-term clinical success of the device, the volumetric material loss from Exeter femoral head tapers was, in general, small compared with that from larger-diameter MoM head tapers.

AB - AIMS: The purpose of this study was to analyze the incidence of the different ultrasound phenotypes of developmental dysplasia of the hip (DDH), and to determine their subsequent course. PATIENTS AND METHODS: A consecutive series of 28 092 neonates was screened and classified according to the Graf method as part of a nationwide surveillance programme, and then followed prospectively. Abnormal hips were followed until they became normal (Graf type I). Type IIb hips and higher grades were treated by abduction in a Tubinger orthosis until normal. Dislocated hips underwent closed or open reduction. RESULTS: Overall, 90.2% of hips were normal at birth. Type IIa hips (8.9%) became normal at a median of six weeks (interquartile range (IQR) 6 to 9). Type IIc and IId hips (0.67%) became normal after ten weeks (IQR 7 to 13). There were 19 type lll and eight type lV hips at baseline. There were 24 closed reductions and one open reduction. No late presentations of DDH were detected within the first five years of life. CONCLUSION: The incidence of DDH was eight per 1000 live births. The treatment rate was 1% (n = 273). The rate of first operations on the newborn hip was 0.86, and rate of open surgery was 0.04. The cumulative rate of open surgery was 0.07. The authors take the view that early identification and treatment in abduction of all dysplastic hips in early childhood reduces the rate of open reduction and secondary DDH-related surgery later in life.

AB - AIMS: Total ankle arthroplasty (TAA) surgery is complex and attracts a wide variety of complications. The literature lacks consistency in reporting adverse events and complications. The aim of this article is to provide a comprehensive analysis of each of these complications from a literature review, and to compare them with rates from our Unit, to aid clinicians with the process of informed consent. PATIENTS AND METHODS: A total of 278 consecutive total ankle arthroplasties (251 patients), performed by four surgeons over a six-year period in Wrightington Hospital (Wigan, United Kingdom) were prospectively reviewed. There were 143 men and 108 women with a mean age of 64 years (41 to 86). The data were recorded on each follow-up visit. Any complications either during initial hospital stay or subsequently reported on follow-ups were recorded, investigated, monitored, and treated as warranted. Literature search included the studies reporting the outcomes and complications of TAA implants. RESULTS: There were wound-healing problems in nine ankles (3.2%), superficial infection in 20 ankles (7.2%), and deep infection in six ankles (2.2%). Intraoperative fractures occurred in medial malleoli in 27 ankles (9.7%) and in lateral malleoli in four ankles (1.4%). Aseptic loosening and osteolysis were seen 16 ankles (5.8%). Fracture of the polyethylene component occurred in one ankle (0.4%) and edge loading in seven ankles (2.5%). We observed medial gutter pain in 31 ankles (11.1%). The incidence of thromboembolism occurred in two ankles (0.7%). The results were found to be comparable to the previously reported complications of total ankle arthroplasty in the literature. CONCLUSION: Total ankle arthroplasty continues to evolve and improve the ankle function. Despite high overall complication rates with TAA surgery, most complications appear to be minor and do not affect final clinical outcome. Our results and literature review will help in the consent process and provide detailed complication rates for an informed consent. Cite this article: Bone Joint J 2018;100-B:1352-8. PMID- 30295528 TI - Antioxidant-stabilized highly crosslinked polyethylene in total knee arthroplasty. AB - AIMS: The aim of this study was to evaluate the surface damage, the density of crosslinking, and oxidation in retrieved antioxidant-stabilized highly crosslinked polyethylene (A-XLPE) tibial inserts from total knee arthroplasty (TKA), and to compare the results with a matched cohort of standard remelted highly crosslinked polyethylene (XLPE) inserts. MATERIALS AND METHODS: A total of 19 A-XLPE tibial inserts were retrieved during revision TKA and matched to 18 retrieved XLPE inserts according to the demographics of the patients, with a mean length of implantation of 15 months (1 to 42). The percentage areas of PE damage on the articular surfaces and the modes of damage were measured. The density of crosslinking of the PE and oxidation were measured at loaded and unloaded regions on these surfaces. RESULTS: A-XLPE inserts had higher rates of burnishing and lower rates of pitting and scratching compared with XLPE. There were no differences in the density of crosslinking at loaded and unloaded regions. A-XLPE showed higher oxidation indices in the unloaded surface region compared with XLPE. There were no differences in the levels of oxidation in the loaded regions. CONCLUSION: Retrieval analysis of A-XLPE did not reflect a clinically relevant difference in surface damage, density of crosslinking, or oxidation compared with XLPE tibial inserts at short-term evaluation.

AB - AIMS: This study reports the outcomes of a technique of soft-tissue coverage and Chopart amputation for severe crush injuries of the forefoot. PATIENTS AND METHODS: Between January 2012 to December 2016, 12 patients (nine male; three female, mean age 38.58 years; 26 to 55) with severe foot crush injury underwent treatment in our institute. All patients were followed-up for at least one year. Their medical records, imaging, visual analogue scale score, walking ability, complications, and functional outcomes one year postoperatively based on the American Orthopedic Foot and Ankle Society (AOFAS) and 36-Item Short-Form Health Survey (SF-36) scores were reviewed. RESULTS: The mean length of follow-up was 18.6 months (13 to 28). Two patients had a local infection, flap necrosis was seen in one patient, and one patient experienced a skin graft wound healing delay. Of the 12 patients, one had persistent infection and eventually required below-knee amputation, but pain-free walking was achieved in all the other patients. The mean one-year postoperative AOFAS and SF-36 scores were 75.6 (68 to 80) and 82 (74 to 88), respectively. CONCLUSION: Although our sample size was small, we believe that this treatment method may be a valuable alternative for treating severe foot crush injuries.

AB - AIMS: The aim of this study was to describe temporal trends and survivorship of total hip arthroplasty (THA) in very young patients, aged <= 20 years. PATIENTS AND METHODS: A descriptive observational study was undertaken using data from the National Joint Registry (NJR) for England, Wales, Northern Ireland and the Isle of Man between April 2003 and March 2017. All patients aged <= 20 years at the time of THA were included and the primary outcome was revision surgery. Descriptive statistics were used to summarize the data and Kaplan-Meier estimates calculated for the cumulative implant survival. RESULTS: A total of 769 THAs were performed in 703 patients. The median follow-up was 5.1 years (interquartile range (IQR) 2.6 to 7.8). Eight patients died and 35 THAs were revised. The use of metal-on-metal (MoM) bearings and resurfacing procedures declined after 2008. The most frequently recorded indications for revision were loosening (20%) and infection (20%), although the absolute risk of these events occurring was low (0.9%). Factors associated with lower implant survival were MoM and metal-on polyethylene (MoP) bearings and resurfacing arthroplasty ( vs ceramic-on polyethylene (CoP) and ceramic-on-ceramic (CoC) bearings, p = 0.002), and operations performed by surgeons who undertook few THAs in this age group as recorded in the NJR ( vs those with five or more recorded operations, p = 0.030). Kaplan-Meier estimates showed 96% (95% confidence interval (CI) 94% to 98%) survivorship of implants at five years. CONCLUSION: Within the NJR, the overall survival for very young patients undergoing THA exceeded 96% during the first five postoperative years. In the absence of studies that can better account for differences in the characteristics of the patients, surgeons should consider the association between early revision and the type of implant, the number of THAs performed in these patients, and the bearing surface when performing THA in very young patients.

AB - AIMS: The purpose of this study was to evaluate spinopelvic mechanics from standing and sitting positions in subjects with and without femoroacetabular impingement (FAI). We hypothesize that FAI patients will experience less flexion at the lumbar spine and more flexion at the hip whilst changing from standing to sitting positions than subjects without FAI. This increase in hip flexion may contribute to symptomatology in FAI. PATIENTS AND METHODS: Male subjects were prospectively enrolled to the study (n = 20). Mean age was 31 years old (22 to 41). All underwent clinical examination, plain radiographs, and dynamic imaging using EOS. Subjects were categorized into three groups: non-FAI (no radiographic or clinical FAI or pain), asymptomatic FAI (radiographic and clinical FAI but no pain), and symptomatic FAI (patients with both pain and radiographic FAI). FAI was defined as internal rotation less than 15 degrees and alpha angle greater than 60 degrees . Subjects underwent standing and sitting radiographs in order to measure spine and femoroacetabular flexion. RESULTS: Compared with non-FAI controls, symptomatic patients with FAI had less flexion at the spine (mean 22 degrees , sd 12 degrees , vs mean 35 degrees , sd 8 degrees ; p = 0.04) and more at the hip (mean 72 degrees , sd 6 degrees , vs mean 62 degrees , sd 8 degrees ; p = 0.047). Subjects with asymptomatic FAI had more spine flexion and similar hip flexion when compared to symptomatic FAI patients. Both FAI groups also sat with more anterior pelvic tilt than control patients. There were no differences in standing alignment among groups. CONCLUSION: Symptomatic patients with FAI require more flexion at the hip to achieve sitting position due to their inability to compensate through the lumbar spine. With limited spine flexion, FAI patients sit with more anterior pelvic tilt, which may lead to impingement between the acetabulum and proximal femur. Differences in spinopelvic mechanics between FAI and non-FAI patients may contribute to the progression of FAI symptoms. Cite this article: Bone Joint J 2018;100-B:1275-9. PMID- 30295532 TI - A systematic review of meta-analyses in orthopaedic surgery between 2000 and 2016. AB - AIMS: The aims of this systematic review were to describe the quantity and methodological quality of meta-analyses in orthopaedic surgery published during the last 17 years. MATERIALS AND METHODS: MEDLINE, EMBASE, and PubMed, between 1 January 2000 and 31 December 2016, were searched for meta-analyses in orthopaedic surgery dealing with at least one surgical intervention. Meta-analyses were included if the interventions involved a human muscle, ligament, bone or joint. RESULTS: A total of 392 meta-analyses met eligibility criteria, for which the mean AMSTAR quality score was 7.1/11. There was a positive correlation between the year of publication and the quality of the meta-analysis (r = 0.238, p < 0.001). Between 2000 and 2011, the mean AMSTAR score corresponded to that of a medium quality review. However, between 2012 and 2016, the mean scores have been consistently equivalent to those of a high-quality review. The number of meta analyses published increased 10-fold between 2005 and 2014. CONCLUSION: The quantity and quality of meta-analyses in orthopaedic surgery which have been published has increased, reaching a plateau in 2012. Methodological flaws remain to be addressed in future meta-analyses in order to continue increasing the quality of the orthopaedic literature. Cite this article: Bone Joint J 2018;100 B:1270-4. PMID- 30295533 TI - Functional acetabular component alignment. PMID- 30295534 TI - What preoperative factors predict postoperative sitting pelvic position one year following total hip arthroplasty? AB - AIMS: The aims of this study were to measure sagittal standing and sitting lumbar pelvic-femoral alignment in patients before and following total hip arthroplasty (THA), and to consider what preoperative factors may influence a change in postoperative pelvic position. PATIENTS AND METHODS: A total of 161 patients were considered for inclusion. Patients had a mean age of the remaining 61 years (sd 11) with a mean body mass index (BMI) of 28 kg/m2 (sd 6). Of the 161 patients, 82 were male (51%). We excluded 17 patients (11%) with spinal conditions known to affect lumbar mobility as well as the rotational axis of the spine. Standing and sitting spine-to-lower-limb radiographs were taken of the remaining 144 patients before and one year following THA. Spinopelvic alignment measurements, including sacral slope, lumbar lordosis, and pelvic incidence, were measured. These angles were used to calculate lumbar spine flexion and femoroacetabular hip flexion from a standing to sitting position. A radiographic scoring system was used to identify those patients in the series who had lumbar degenerative disc disease (DDD) and compare spinopelvic parameters between those patients with DDD (n = 38) and those who did not (n = 106). RESULTS: Following THA, patients sat with more anterior pelvic tilt (mean increased sacral slope 18 degrees preoperatively versus 23 degrees postoperatively; p = 0.001) and more lumbar lordosis (mean 28 degrees preoperatively versus 35 degrees postoperatively; p = 0.001). Preoperative change in sacral slope from standing to sitting (p = 0.03) and the absence of DDD (p = 0.001) correlated to an increased change in postoperative sitting pelvic alignment. CONCLUSION: Sitting lumbar-pelvic-femoral alignment following THA may be driven by hip arthritis and/or spinal deformity. Patients with DDD and fixed spinopelvic alignment have a predictable pelvic position one year following THA. Patients with normal spines have less predictable postoperative pelvic position, which is likely to be driven by hip stiffness. Cite this article: Bone Joint J 2018;100-B:1289-96. PMID- 30295535 TI - Increased complications in geriatric patients with a fracture of the hip whose postoperative weight-bearing is restricted. AB - AIMS: The aims of this study were to evaluate the incidence of postoperatively restricted weight-bearing and its association with outcome in patients who undergo surgery for a fracture of the hip. PATIENTS AND METHODS: Patient aged > 60 years undergoing surgery for a hip fracture were identified in the 2016 National Surgical Quality Improvement Program (NSQIP) Hip Fracture Targeted Procedure Dataset. Analysis of the effect of restricted weight-bearing on adverse events, delirium, infection, transfusion, length of stay, return to the operating theatre, readmission and mortality within 30 days postoperatively were assessed. Multivariate regression analysis was used to adjust for confounding demographic, comorbid and procedural characteristics. RESULTS: Of the 4918 patients who met inclusion criteria, 3668 (63.53%) were allowed to weight-bear as tolerated postoperatively. Controlling for patient and procedural factors, multivariate odds of any adverse event, major adverse event, delirium, infection, transfusion, length of stay >= 75th percentile (six days) and mortality within 30 days were all higher in patients with weight-bearing restrictions. Notably, there were no differences for thromboembolic events, return to the operating theatre or readmission within 30 days between the groups. CONCLUSION: Elderly patients with a fracture of the hip with postoperative weight-bearing restrictions have a significantly greater risk of developing most adverse events compared with those who are encouraged to weight-bear as tolerated. These findings emphasize the importance of immediate weight-bearing as tolerated to optimize the outcome in these frail patients; however nearly 25% of surgeons fail to meet this evidence based guideline.

AB - AIMS: Recent studies of nonoperatively treated displaced midshaft clavicular fractures have shown a high incidence of nonunion and unsatisfactory functional outcome. Some studies have shown superior functional results and higher rates of healing following operative treatment. The aim of this study was to compare the outcome in these patients after nonoperative management with those treated with fixation. PATIENTS AND METHODS: In a multicentre, parallel randomized controlled trial, 146 adult patients with an acute displaced fracture of the midthird of the clavicle were randomized to either nonoperative treatment with a sling (71, 55 men and 16 women with a mean age of 39 years, 18 to 60) or fixation with a pre contoured plate and locking screws (75, 64 men and 11 women with a mean age of 40 years, 18 to 60). Outcome was assessed using the Disabilities of the Arm, Shoulder and Hand (DASH) Score, the Constant Score, and radiographical evidence of union. Patients were followed for one year. RESULTS: A total of 60 patients in the nonoperative group and 64 in the operative group completed one-year follow up. At three months' follow-up, both the median DASH (1.7 vs 8.3) and median Constant scores (97 vs 90) were significantly better in the operated group (both p = 0.02). After six months and one year, there was no difference in the median DASH or Constant scores. The rate of nonunion was lower in the operative group (2 vs 11 patients, p < 0.02). Nine patients in the nonoperative group underwent surgery for nonunion. The plate was subsequently removed in 16 patients (25%). One patient had a new fracture after removal of the plate and one underwent revision surgery for failure of fixation. CONCLUSION: Fixation of a displaced midshaft clavicular fracture using a pre-contoured plate and locking screws results in faster functional recovery and a higher rate of union compared with nonoperative management, but the function of the shoulder is equal after six months and at one year.

PMID- 30295537 TI - Pelvic positioning in the supine position leads to more consistent orientation of the acetabular component after total hip arthroplasty. AB - AIMS: This study aims to: determine the difference in pelvic position that occurs between surgery and radiographic, supine, postoperative assessment; examine how the difference in pelvic position influences subsequent component orientation; and establish whether differences in pelvic position, and thereafter component orientation, exist between total hip arthroplasties (THAs) performed in the supine versus the lateral decubitus positions. PATIENTS AND METHODS: The intra- and postoperative anteroposterior pelvic radiographs of 321 THAs were included; 167 were performed with the patient supine using the anterior approach and 154 were performed with the patient in the lateral decubitus using the posterior approach. The inclination and anteversion of the acetabular component was measured and the difference (Delta) between the intra- and postoperative radiographs was determined. The target zone was inclination/anteversion of 40 degrees /20 degrees (+/- 10 degrees ). Changes in the tilt, rotation, and obliquity of the pelvis on the intra- and postoperative radiographs were calculated from Deltainclination/anteversion using the Levenberg-Marquardt algorithm. RESULTS: The mean postoperative inclination/anteversion was 40 degrees (+/- 8 degrees )/23 degrees (+/- 9 degrees ) with Deltainclination and/or Deltaanteversion > +/- 10 degrees in 74 (21%). Intraoperatively, the pelvis was anteriorly tilted by a mean of 4 degrees (+/- 10 degrees ), internally rotated by a mean of 1 degrees (+/- 10 degrees ) and adducted by a mean of 1 degrees (+/- 5 degrees ). Having Deltainclination and/or Deltaanteversion > +/- 10 degrees was associated with a 3.5 odds ratio of having the acetabular component outside the target zone. A greater proportion of THAs that were undertaken with the patient in the lateral decubitus position had Deltainclination and/or Deltaanteversion > +/- 10 degrees (35.3%, 54/153) compared with those in the supine position (4.8%, 8/167; p < 0.001). A greater number of acetabular components were within the target zone in THAs undertaken with the patient in the supine position (72%, 120/167), compared with those in the lateral decubitus position (44%, 67/153; p < 0.001). Intraoperatively, the pelvis was more anteriorly tilted (p < 0.001) and more internally rotated (p = 0.04) when the patient was in the lateral decubitus position. CONCLUSION: The pelvic position is more reliable when the patient is in the supine position, leading to more consistent orientation of the acetabular component. Significant differences in pelvic tilt and rotation are seen with the patient in the lateral decubitus position. Cite this article: Bone Joint J 2018;100-B:1280-8. PMID- 30295538 TI - Intraoperative placement of total hip arthroplasty components with robotic-arm assisted technology correlates with postoperative implant position. AB - AIMS: The aim of this study was to evaluate the accuracy of implant placement when using robotic assistance during total hip arthroplasty (THA). PATIENTS AND METHODS: A total of 20 patients underwent a planned THA using preoperative CT scans and robotic-assisted software. There were nine men and 11 women (n = 20 hips) with a mean age of 60.8 years (sd 6.0). Pelvic and femoral bone models were constructed by segmenting both preoperative and postoperative CT scan images. The preoperative anatomical landmarks using the robotic-assisted system were matched to the postoperative 3D reconstructions of the pelvis. Acetabular and femoral component positions as measured intraoperatively and postoperatively were evaluated and compared. RESULTS: The system reported accurate values for reconstruction of the hip when compared to those measured postoperatively using CT. The mean deviation from the executed overall hip length and offset were 1.6 mm (sd 2.9) and 0.5 mm (sd 3.0), respectively. Mean combined anteversion was similar and correlated between intraoperative measurements and postoperative CT measurements (32.5 degrees , sd 5.9 degrees versus 32.2 degrees , sd 6.4 degrees ; respectively; R2 = 0.65; p < 0.001). There was a significant correlation between mean intraoperative (40.4 degrees , sd 2.1 degrees ) acetabular component inclination and mean measured postoperative inclination (40.12 degrees , sd 3.0 degrees , R2 = 0.62; p < 0.001). There was a significant correlation between mean intraoperative version (23.2 degrees , sd 2.3 degrees ), and postoperatively measured version (23.0 degrees , sd 2.4 degrees ; R2 = 0.76; p < 0.001). Preoperative and postoperative femoral component anteversion were significantly correlated with one another (R2 = 0.64; p < 0.001). Three patients had CT scan measurements that differed substantially from the intraoperative robotic measurements when evaluating stem anteversion. CONCLUSION: This is the first study to evaluate the success of hip reconstruction overall using robotic assisted THA. The overall hip reconstruction obtained in the operating theatre using robotic assistance accurately correlated with the postoperative component position assessed independently using CT based 3D modelling. Clinical correlation during surgery should continue to be practiced and compared with observed intraoperative robotic values. Cite this article: Bone Joint J 2018;100-B:1303-9. PMID- 30295539 TI - A randomized prospective study comparing mobile-bearing against fixed-bearing PFC Sigma cruciate-retaining total knee arthroplasties with ten-year minimum follow up. AB - AIMS: This study compares the PFC total knee arthroplasty (TKA) system in a prospective randomized control trial (RCT) of the mobile-bearing rotating platform (RP) TKA against the fixed-bearing (FB) TKA. This is the largest RCT with the longest follow-up where cruciate-retaining PFC total knee arthroplasties are compared in a non-bilateral TKA study. PATIENTS AND METHODS: A total of 167 patients (190 knees with 23 bilateral cases), were recruited prospectively and randomly assigned, with 91 knees receiving the RP and 99 knees receiving FB. The mean age was 65.5 years (48 to 82), the mean body mass index (BMI) was 29.7 kg/m2 (20 to 52) and 73 patients were female. The Knee Society Score (KSS), Knee Society Functional Score (KSFS), Oxford Knee Score (OKS), Western Ontario and McMaster Universities Arthritis Index (WOMAC), and 12-Item Short-Form Health Survey Physical and Mental Component Scores (SF-12 PCS, SF-12 MCS) were gathered and recorded preoperatively, at five-years' follow-up, and at ten years' follow up. Additionally, Knee Injury and Osteoarthritis Outcome Scores (KOOS) were collected at five- and ten-year follow-ups. The prevalence of radiolucent lines (RL) on radiographs and implant survival were recorded at five- and ten-year follow-ups. RESULTS: At the ten-year follow-up, the RP group (n = 39) had a statistically significant superior score in the OKS (p = 0.001), WOMAC (p = 0.023), SF-12 PCS (p = 0.019), KOOS Activities of Daily Living (ADL) (p = 0.010), and KOOS Sport and Recreation (Sport/Rec) (p = 0.006) compared with the FB group (n = 46). The OKS, SF-12 PCS, and KOOS Sport/Rec at ten years had mean scores above the minimal clinically important difference (MCID) threshold. There was no significant difference in prevalence of radiolucency between groups at five years' follow-up (p = 0.449), nor at ten-years' follow-up (p = 0.08). Implant survival rate at 14 years postoperative was 95.2 (95% CI 90.7 to 99.8) and 94.7 (95% CI 86.8 to 100.0) for the RP and FB TKAs, respectively. CONCLUSION: At ten year follow-up, the mobile-bearing knee joint arthroplasty had statistically and clinically relevant superior OKS, SF-12 PCS, and KOOS (Sport/Rec) than the fixed bearing platform. No difference was seen in prevalence of radiolucent lines. There was a greater than 94% implant survival rate for both cohorts at 14 years. Cite this article: Bone Joint J 2018;100-B:1336-44. PMID- 30295540 TI - Describing the Use of Animals in Animal-Assisted Intervention Research. AB - Currently, there has been growing attention to animal welfare in animal-assisted interventions (AAI). However, there is a lack of scrutiny regarding what steps to take to ensure animal wellbeing during AAI research. The Institutional Animal Care and Use Committee (IACUC) reviews, monitors, and approves all research involving animal subjects in order to ensure an animal's ethical and humane treatment. However, AAI publications rarely report IACUC approval. The purpose of this critical review was to determine the frequency of IACUC approval and to report the descriptions of animal use in AAI research publications. In the 139 articles reviewed, 14 (10%) studies reported attaining IACUC approval; 4/139 (3%) reported an adverse outcome on at least one animal used in the study. The publications inconsistently reported the training or certification and veterinary care of the animals. Lacking IACUC approval in AAI studies indicates that the field underutilizes this method of monitoring animal health and welfare. The IACUC should assess, approve, and monitor research protocols involving animals prior to conducting every study to safeguard AAI animal welfare. PMID- 30295541 TI - An overview of surgical sealant devices: current approaches and future trends. AB - INTRODUCTION: Wound leakage is a common complication after surgical incision or resection. In the past, a variety of clinically-approved surgical sealant devices have been used as an adjunct or alternative to conventional means of tissue sealing. However, there is still an unmet need for a sealant that can be universally applied over a wide range of clinical applications. This has further driven the emergence of both novel liquid surgical sealant devices and active hemostatic sealant patches to deal with the increasing complexity of surgical interventions in the field of hemorrhage control and wound leakage. Areas covered: Emphasizing the literature from the past 5 years, this review covers the current offering of natural, synthetic or composite surgical sealant devices in liquid or patch form, their appropriate clinical indications as well as emerging technologies, strategies and products. Expert commentary: Recent years have been marked by dramatic and continuous progress towards the development of novel surgical sealant devices and their rigorous clinical testing. In addition, next generation sealant formulations such as active hemostatic sealant patches and bio inspired or nanoparticle-based sealant concepts have been developed and are constantly being evaluated and refined. PMID- 30295542 TI - Neurosarcoidosis As a Rare Differential Diagnosis for Single Or Multiple Lesions of the Nervous System. AB - OBJECTIVE: Sarcoidosis is a multisystemic granulomatous disease of unknown cause which affects the lung or bilateral hilar lymphadenopathy in over 90% of the cases. Neurosarcoidosis (NS) is rare and accounts for approximately 5 - 15% of the cases. Involvement of all parts of the central and peripheral nervous system is possible with various clinical symptoms, e. g. seizures, hydrocephalus, optic/facial nerve palsy or hearing loss. METHODS: We screened the neuropathological data bases and the medical records of two neurosurgical university hospitals for cases of NS. All these cases had been verified by surgical biopsy. We retrospectively evaluated the patient's records with special regard to the histopathology reports and specific clinical symptoms. RESULTS: We identified 9 cases of NS between 1994 and 2014 (3 female, 6 male patients). The average age at the time of diagnosis of NS was 41,4 years. Various clinical symptoms like hydrocephalus (n = 3), seizures (n = 1), meningitis (n = 1), optical nerve involvment with vision disorder (n = 1), myelitis with paraplegia (n = 1), mastoiditis with hearing loss (n = 1), back pain syndrome (n = 2) were present. 7 patients were treated with corticosteroids, 1 patient with cyclophosphamide and 1 with a combination of corticosteroids and methotrexate. CONCLUSION: NS is a rare but potentially life-threatening disease. It is difficult to distinguish sarcoidosis from other granulomatous diseases, infectious diseases like tuberculosis, multiple sclerosis or neoplasm. For a definite diagnosis, a neurosurgical biopsy with histological evidence of noncaseating epithelioid cell granulomas is required, followed by multidisciplinary treatment. PMID- 30295543 TI - Efficacy of the combination of carteolol hydrochloride + latanoprost in the treatment of glaucoma and ocular hypertension. AB - INTRODUCTION: The only evidence-based mechanism for prevention and treatment of glaucomatous optic neuropathy is decreasing the intraocular pressure (IOP). Prescribing multiple ocular hypotensive agents, such as the combination of carteolol and latanoprost, may synergistically improve IOP; however, doing so may increase the complexity of a medication regimen, in turn, impairing patient adherence. Fixed-combination glaucoma medications offer convenience and effectiveness. New to this class of glaucoma medication is fixed combination carteolol-latanoprost (FCCL). Area covered: This review intends to give the reader a better understanding of the efficacy of the combination of carteolol and latanoprost separately, and where FCCL fits into the vast medical arsenal of IOP drops. Furthermore, it outlines the particular pharmacologic mechanisms targeted, the pharmacokinetics, effectiveness, the advantages of fixed-combination administration, and tolerability. Expert opinion: The combination of carteolol and latanoprost, separately or in a fixed-combination, is more effective than either drug alone. Given the early stage in development of FCCL, it has yet to be determined how FCCL compares to other fixed-combination medications. However, pending further approval, fixed-combination carteolol-latanoprost may represent a reasonable alternative for a patient whose IOP is inadequately controlled on a prostaglandin analog alone and for whom a simplified combination is preferred. PMID- 30295544 TI - Structured Model of Neurorehab: A Pilot Study of Modern Multitouch Technology and Virtual Reality Platforms for Training Sociocognitive Deficit in Children with Acquired Brain Injury. AB - Social competence is often impaired in children with acquired brain injury (ABI), but evidence-based rehabilitation has remained undeveloped. This pilot-study aimed to create a structured model for sociocognitive rehabilitation for children with ABI. A total of 32 children aged 8-13 years participated: 22 with ABI epilepsy, traumatic brain injury, or tic disorder and 10 healthy controls. Interactive computer-based applications were implemented into rehabilitation design using multitouch-multiuser tabletop (MMT) devices: Snowflake MultiTeach (MT) and Diamond Touch Table (DTT), plus MediqVR virtual reality (VR) platform. At baseline, patients demonstrated social incompetence compared to healthy controls. Post-training evaluations showed that rehabilitation on Snowflake MT improved children's executive and cooperation skills. DTT developed new communication and language skills, metacognitive skills, and coping with difficult social situations. This structured model for social competence rehabilitation helps therapists to understand the objectives and tools for improving social and cooperation skills in children with ABI. We provide practical recommendations using next-generation devices, which are effective and motivating for children. PMID- 30295545 TI - Timing and Sequence of Events: HIV Status Disclosure, Condomless Anal Sex, and Sexual Agreement Formation Among Same-Sex Male Couples. AB - Despite the implications for human immunodeficiency virus (HIV) prevention and sexual health, little is known about the timing and chronological order of when same-sex male couples disclose their HIV serostatus, establish a sexual agreement, and first engage in condomless anal sex (CAS) in their relationships. Dyadic data from 357 dyads were used to describe when these respective events occurred; whether members of a couple concurred about when the events happened; and the chronological order of these events. For many, disclosure and CAS happened within the first month, whereas an agreement tended to occur much later (if at all). Couples' concordance of when disclosure and agreement formation happened differed by their serostatus, whereas there was little difference by serostatus for CAS. The chronological order of these events revealed interesting patterns and varied substantially. Although two-thirds of partners reported disclosure had occurred first, some reported events happening on the same day. These findings reveal that the first few months in a same-sex male couple's relationship is a critical time period for when information and decisions about sexual health occur. Suggestions are provided for how current and future HIV prevention efforts could assist couples with their sexual health needs. PMID- 30295547 TI - Executive functions and clinical symptoms in children exposed to maltreatment. AB - There is evidence of an association between childhood maltreatment and lifelong cognitive impairment. Few studies investigate cognitive functioning in maltreated children. The objective of this study was to investigate whether there are differences in executive processing between maltreated and nonmaltreated children. Additionally, clinical symptoms were compared between groups and possible associations between clinical symptoms, and deficits in executive functions were investigated. The sample consisted of 55 children (8-12 years), 30 with a history of maltreatment and 25 with no history of maltreatment. An interview was conducted with the child's legal guardian and instruments were administered: Juvenile Victimization Questionnaire (JVQ), Child Behavior Checklist (CBCL), and Spence Children's Anxiety Scale (SCAS). The following clinical instruments were administered to the children: JVQ, Trauma Symptom Checklist for Children (TSCC), and Children's Depression Inventory (CDI). Children underwent neuropsychological assessment. Data were analyzed by comparing the groups for clinical and cognitive variables. Differences were found between the groups in all executive functions. Most clinical symptomatology scales showed differences between the groups. Few associations were found between clinical and executive impairment profiles. Cognitive stimulation interventions, focused on inhibitory control, should be proposed in combination with psychotherapy.

PMID- 30295548 TI - Optimal medical treatment of hypertension in patients with coronary artery disease. AB - INTRODUCTION: Coronary artery disease (CAD) remains the leading cause of mortality and morbidity worldwide, and hypertension is its most prevalent modifiable risk factor. Patients with CAD and concomitant hypertension are a special population with distinct physiologic and structural alterations. Optimal blood pressure (BP) control in this population has been linked with reduction in adverse outcomes, however, excessive lowering of BP could jeopardize myocardial and cerebral perfusion. Areas covered: Authors highlight the prevalence of the CAD and hypertension dyad, as well as the implications of various structural and physiological changes in this population. Subsequently, available data on optimal BP targets in such patients, and lastly the J-curve phenomenon as well as antihypertensive agent use are discussed. Expert commentary: Current guideline recommendations are based on data from trials such as SPRINT and ACCORD which did not specifically focus on the CAD population. Based on data from observational studies and post hoc analyses, the best therapeutic systolic (SBP) and diastolic (DBP) targets may be ~ 130 mmHg and ~ 80 mmHg, respectively. Caution should be taken to not lower SBP below 120 mmHg and DBP below 60 mmHg.

PMID- 30295550 TI - Quantification of phenolic acid metabolites in humans by LC-MS: a structural and targeted metabolomics approach. AB - AIM: Co-metabolism between a human host and the gastrointestinal microbiota generates many small phenolic molecules such as 3-hydroxy-3-(3 hydroxyphenyl)propanoic acid (3,3-HPHPA), which are reported to be elevated in schizophrenia and autism. Characterization of these chemicals, however, has been limited by analytic challenges. METHODOLOGY/RESULTS: We applied HPLC to separate and quantify over 50 analytes, including multiple structural isomers of 3,3-HPHPA in human cerebrospinal fluid, serum and urine. Confirmation of identity was provided by NMR, by MS and other detection methods. The highly selective methods support rapid quantification of multiple metabolites and exhibit superior chromatographic behavior. CONCLUSION: An improved ultra-HPLC-MS/MS and structural approaches can accurately quantify 3,3-HPHPA and related analytes in human biological matrices.

AB - AIM: The combination of levodopa with carbidopa has been used for treatment of Parkinson's disease being an important therapy in dopamine level control in the brain. Both are very polar compounds becoming a challenge for analysis by LC MS/MS. MATERIALS & METHODS: In this work, it was developed and validated a sensitive bioanalytical method by UHPLC-MS/MS for simultaneous levodopa and carbidopa quantification in human plasma using a fast protein precipitation method. Moreover, the bioanalytical method was applied to a pharmacokinetic study in healthy volunteers. RESULTS/CONCLUSION: The results demonstrated a sensitive and adequate method for application to pharmacokinetic/bioequivalence studies. PMID- 30295552 TI - Percutaneous retrogasserian glycerol rhizotomy for trigeminal neuralgia: an alternative technique. AB - BACKGROUND: One of the challenges faced by the modern-day NHS is workplace shortages, and experienced radiographers for intra-operative neurosurgical imaging is one such scenario. We describe our method for Percutaneous Retrogasserian Glycerol Rhizotomy (PRGR) using frameless neuronavigation which can be used effectively in such scenarios. METHOD: Stealth neuronavigation is used for needle placement within the foramen ovale and injection of glycerol, under sedation. RESULTS: In our experience of ten procedures, it is accurate, safe and effective. Good results were obtained on all occasions. It can be repeated as often as necessary using the same Stealth(r) CT scan and reduces exposure for staff and patients, where repeated injections are required. CONCLUSION: This simple modification of PRGR technique is effective and safe provided the surgeon has previous experience in undertaking this procedure. PMID- 30295553 TI - Repeated pulmonary exposures to zinc ions enhance inflammatory responses to subsequent metal exposures. AB - AIM OF STUDY: Metal contaminants contribute to adverse human health effects via acute and chronic exposures. Acute metal exposures followed by prolonged secondary metal exposures may elicit exaggerated inflammatory responses in certain individuals. The aim of this study is to determine whether repeated pulmonary exposures to zinc chloride (ZnCl2) alter subsequent responses to zinc or cerium exposures. MATERIALS AND METHODS: Rats were intratracheally (IT) instilled with physiologic saline (n = 24) or 0.05 mg/kg ZnCl2 (n = 16) twice weekly for 4 weeks. Four days after last dosing, the saline group was divided into three subgroups, each IT-instilled with either saline, ZnCl2 or CeCl3 (both at 0.1 mg/kg). The ZnCl2 pre-instilled rats were divided into two subgroups, each instilled with 0.1 mg/kg ZnCl2 or CeCl3. Biomarkers of lung injury/inflammation were assessed in bronchoalveolar lavage (BAL) fluid collected 24 hours later. Oxidative stress was evaluated as total and reduced glutathione in BAL. RESULTS: Increases in inflammatory cells, LDH, albumin, leptin, MCP-1, IP-10, fractalkine, TNFalpha and RANTES were observed in rats instilled with multiple PBS and then with 0.1 mg/kg ZnCl2 and CeCl3. However, rats pre-exposed repeatedly to 0.05 mg/kg ZnCl2 and then challenged with 0.1 mg/kg ZnCl2 or CeCl3 showed even more eosinophils, lymphocytes, and increased concentrations of hemoglobin and MIP 1alpha. Significant reduction in GSH/GSSG ratios in BAL in response to all ZnCl2 or CeCl3 exposures indicated oxidative stress. CONCLUSION: Previous exposure to zinc ions increases responsiveness to subsequent exposures to zinc and cerium ions. These findings suggest enhanced sensitization possibly due to a reduction in antioxidant defenses. PMID- 30295554 TI - Impact of baseline neurocognitive functioning on outcomes following rehabilitation of executive function training for veterans with history of traumatic brain injury. AB - Traumatic brain injury (TBI) is common among Veterans, and sequelae frequently include deficits in attention and executive function and problems with emotional regulation. Although rehabilitation has been shown to be effective, it is not clear how patient characteristics such as baseline cognitive status may impact response to rehabilitation in this sample. Explore the relationship between baseline neuropsychological status and postintervention functional outcomes in Veterans with chronic TBI. Thirty-three Veterans with chronic mild-severe TBI completed a neuropsychological evaluation, a functional assessment of executive function (EF), and measures of emotional and everyday functioning pre- and post EF training or control training. Performance on baseline neuropsychological measures was used to cluster participants. Participants' performance at baseline and postintervention assessments was compared by cluster using multivariate analyses of variance (MANOVAs). Cognitive Difficulty (CD; n = 19) and Cognitively Normal (CN; n = 14) clusters were identified. CD was characterized by z <= -.75 on neuropsychological measures of overall attention/EF, working memory, and memory. CD participants performed worse on functional EF assessment and endorsed more PTSD symptoms and community integration problems, at baseline. CD participants improved post-EF training, but not control training, on neuropsychological and functional measures. CN participants did not show statistically significant improvement. For Veterans with chronic TBI, cognitive assessment can aid in identifying functional impairment and assist treatment planning. Cognitive rehabilitation training appears to be a beneficial treatment option for TBI patients with cognitive, emotional, and daily living difficulties. PMID- 30295556 TI - Dysfunctional cerebral autoregulation is associated with delirium in critically ill adults. AB - Delirium is common during critical illness and is associated with morbidity and mortality, but its pathophysiology is unknown. We tested whether dysfunctional cerebral autoregulation (CA) contributes to the development of delirium. Adult patients ( n = 40) with respiratory failure and/or shock were prospectively enrolled. Continuous recordings of regional cerebral oxygen saturation (rSO2) were obtained by near-infrared spectroscopy (NIRS) during the first 72 h of intensive care unit (ICU) admission. CA function was estimated by the cerebral oximetry index (COx), which is the time-varying correlation between rSO2 and mean arterial pressure (MAP). Delirium was assessed daily. The median ICU stay was seven days (IQR 4-13). Twenty-four patients (60%) screened positive for delirium on at least one day during their stay. Taking positive COx values to reflect periods of CA dysfunction, we found that the cumulative duration of CA dysfunction during the first one to three days in the ICU was significantly associated with the subsequent development of delirium. Additionally, we assessed two alternative methods for estimating optimal MAP targets in individual patients. In summary, early disturbances in CA may contribute to delirium, and NIRS-derived rSO2 may be used to identify individual perfusion targets in critically ill patients. PMID- 30295555 TI - Development and reliability of the Prospective Memory Assessment for Children & Youth (PROMACY): A preliminary study in a nonclinical sample. AB - Prospective memory (PM), "remembering to remember," has been linked to important functional outcomes in adults. Studies of PM in children and adolescents would benefit from the development and validation of developmentally appropriate clinical measures with known psychometric properties. The Prospective Memory Assessment for Children & Youth (PROMACY), a performance-based measure of PM, was developed for the Pediatric HIV/AIDS Cohort Study Adolescent Master Protocol, Memory and Executive Functioning Substudy, and includes Summary, Time-, and Event based scores derived from eight trials with an ongoing word search task. Fifty four healthy perinatally HIV-exposed, uninfected children and youth, mean age 13 years, 54% female, 76% Black/non-Hispanic, and 61% impoverished were included in this psychometric analysis. PROMACY Summary Scores demonstrated low, but broadly acceptable internal consistency as measured by Cronbach's alpha and Spearman Brown. Better PROMACY performance was associated with older age, but no other demographic factors. Generally medium-sized correlations were observed between the PROMACY Summary Score and standard clinical measures of retrospective memory, working memory, executive functions, and IQ. Findings from this preliminary psychometric study of nonclinical children and youth provide cautious support for the internal consistency and construct validity of PROMACY's Summary Score that awaits replication and extension in larger samples of healthy children, youth and clinical populations. PMID- 30295557 TI - Fasting and postprandial serum bile acids after RYGB surgery. PMID- 30295558 TI - Small vessel disease is associated with altered cerebrovascular pulsatility but not resting cerebral blood flow. AB - Cerebral small vessel disease (SVD) contributes to 25% of ischemic strokes and 45% of dementias. We aimed to investigate the role of cerebral blood flow (CBF) and intracranial pulsatility in SVD. We scanned 60 patients with minor ischemic stroke, representing a range of white matter hyperintensities (WMH). We rated WMH and perivascular spaces (PVS) using semi-quantitative scales and measured WMH volume. We measured flow and pulsatility in the main cerebral vessels and cerebrospinal fluid (CSF) using phase-contrast MRI. We investigated the association between flow, pulsatility and SVD features. In 56/60 patients (40 male, 67.8+/-8.3 years) with complete data, median WMH volume was 10.7 mL (range 1.4-75.0 mL), representing median 0.77% (0.11-5.17%) of intracranial volume. Greater pulsatility index (PI) in venous sinuses was associated with larger WMH volume (e.g. superior sagittal sinus, beta = 1.29, P < 0.01) and more basal ganglia PVS (e.g. odds ratio = 1.38, 95% confidence interval 1.06, 1.79, per 0.1 increase in superior sagittal sinus PI) independently of age, sex and blood pressure. CSF pulsatility and CBF were not associated with SVD features. Our results support a close association of SVD features with increased intracranial pulsatility rather than with low global CBF, and provide potential targets for mechanistic research, treatment and prevention of SVD.

AB - OBJECTIVE: Tinnitus is one of the most common somatic symptoms to affect humanity. Prevalence rates in adult populations range from 8.2 to 20.1%. Our aim was to understand the beliefs and interpretations of tinnitus and the experience of living with it. DESIGN: An in depth grounded theory interview study. Grounded theory is an inductive approach to developing theory. SAMPLE: Thirteen contrasting people with tinnitus who had sought help from clinical services in England. RESULTS: We identified that the thinking patterns that people held around their tinnitus impacted how they experienced it. A core category emerged from the data, "sense making". Around "sense making" eight other themes operated. Results are discussed in relation to the literature on tinnitus acceptance and beliefs. CONCLUSIONS: The aim of interventions is to foster understanding and enhance perceptions of control, which may minimise the emotional impact of tinnitus and reduce the perceived severity of consequences. PMID- 30295560 TI - Hypertension, dietary salt and cognitive impairment. AB - Dementia is growing at an alarming rate worldwide. Although Alzheimer disease is the leading cause, over 50% of individuals diagnosed with Alzheimer disease have vascular lesions at autopsy. There has been an increasing appreciation of the pathogenic role of vascular risk factors in cognitive impairment caused by neurodegeneration. Midlife hypertension is a leading risk factor for late-life dementia. Hypertension alters cerebrovascular structure, impairs the major factors regulating the cerebral microcirculation, and promotes Alzheimer pathology. Experimental studies have identified brain perivascular macrophages as the major free radical source mediating neurovascular dysfunction of hypertension. Recent evidence indicates that high dietary salt may also induce cognitive impairment. Contrary to previous belief, the effect is not necessarily associated with hypertension and is mediated by a deficit in endothelial nitric oxide. Collectively, the evidence suggests a remarkable cellular diversity of the impact of vascular risk factors on the cerebral vasculature and cognition. Whereas long-term longitudinal epidemiological studies are needed to resolve the temporal relationships between vascular risk factors and cognitive dysfunction, single-cell molecular studies of the vasculature in animal models will provide a fuller mechanistic understanding. This knowledge is critical for developing new preventive, diagnostic, and therapeutic approaches for these devastating diseases of the mind. PMID- 30295561 TI - Long-term health benefits of stroke prevention with apixaban versus vitamin K antagonist warfarin in patients with non-valvular atrial fibrillation in Germany: a population-based modelling study. AB - BACKGROUND: Patients with non-valvular atrial fibrillation (NVAF) have a five times higher stroke risk. For more than 50 years, vitamin K antagonists (VKAs) have been the primary medication for stroke prevention. Apixaban, a non-vitamin K oral anticoagulant (NOAC), has demonstrated better efficacy and safety characteristics than the VKA warfarin in the ARISTOTLE trial. This study aims to quantify the potential societal effects of using apixaban instead of VKA in the German NVAF population from 2017 to 2030. METHODS: Using an existing Markov model and a dynamic population approach, we modelled the health benefits of apixaban in patients with NVAF compared to VKA therapy in the German population from 2017 to 2030. RESULTS: The results represent the extrapolated direct long-term health benefits of apixaban over VKA therapy for the German NVAF population. From 2017 until 2030, the use of apixaban instead of a VKA could avoid 52,185 major clinical events. This includes 15,383 non-fatal strokes or SEs, 22,483 non-fatal major bleeds, and 14,319 all-cause deaths, which correspond to 109,887 life years gained. CONCLUSION: This study demonstrated that using apixaban instead of VKA for stroke prevention can lead to considerable reduction in cardiovascular events. PMID- 30295562 TI - Chimpanzee Cooperation Is Fast and Independent From Self-Control. AB - Large-scale cooperation is a hallmark of our species and appears to be unique among primates. Yet the evolutionary mechanisms that drove the emergence of humanlike patterns of cooperation remain unclear. Studying the cognitive processes underlying cooperative behavior in apes, our closest living relatives, can help identify these mechanisms. Accordingly, we employed a novel test battery to assess the willingness of 40 chimpanzees to donate resources, instrumentally help others, and punish a culpable thief. We found that chimpanzees were faster to make prosocial than selfish choices and that more prosocial individuals made the fastest responses. Further, two measures of self-control did not predict variation in prosocial responding, and individual performance across cooperative tasks did not covary. These results show that chimpanzees and humans share key cognitive processes for cooperation, despite differences in the scope of their cooperative behaviors.

PMID- 30295564 TI - Meta-Analysis of the Effects of QoI and DMI Fungicide Combinations on Fusarium Head Blight and Deoxynivalenol in Wheat. AB - Field trials were conducted in 17 U.S. states to evaluate the effects of quinone outside inhibitor (QoI) and demethylation inhibitor (DMI) fungicide programs on Fusarium head blight index (IND) and deoxynivalenol (DON) toxin in wheat. Four DMI-only treatments applied at Feekes 10.5.1, five QoI-only treatments applied between Feekes 9 or Feekes 10.5, three QoI+DMI mixtures applied at Feekes 10.5, and three treatments consisting of a QoI at Feekes 9 followed by a DMI at Feekes 10.5.1 were evaluated. Network meta-analytical models were fitted to log transformed mean IND and DON data and estimated contrasts of log means were used to obtain estimates of mean percent controls relative to the nontreated check as measures of efficacy. Results from the meta-analyses were also used to assess the risk of DON increase in future trials. DMI at Feekes 10.5.1 were the most effective programs against IND and DON and the least likely to increase DON in future trials. QoI-only programs increased mean DON over the nontreated checks and were the most likely to do so in future trials, particularly when applied at Feekes 10.5. The effects of QoI+DMI combinations depended on the active ingredients and whether the two were applied as a mixture at heading or sequentially. Following a Feekes 9 QoI application with a Feekes 10.5.1 application of a DMI reduced the negative effect of the QoI on DON but was not sufficient to achieve the efficacy of the Feekes 10.5.1 DMI-only treatments. Our results suggest that one must be prudent when using QoI treatments under moderate to high risk of FHB, particularly where the QoI is used without an effective DMI applied in combination or in sequence.

AB - The clinical efficacy of anti-osteoporotic treatments in old patients is discussed. The aim of this study was to assess if the use of anti-osteoporotic treatments for the secondary prevention of osteoporotic fractures could reduce the risk of refractures in patients over 75 years old in a Fracture Liaison Service. In this population of frail, elderly patients presenting with a recent osteoporotic fracture, we observed that the refracture incidence was similar in the treated group and the untreated group during the first year. However, 30 months after the index fracture, the osteoporosis medication for a year or more reduced the incidence of refractures by 70%.

AB - The purpose of this article is to unpack concepts surrounding "the connection that survives death" between living people and the deceased. The study was designed as the qualitative arm of an integrated project on filial piety in contemporary times, and data were collected from 17 interviews with Korean human service professionals from Australia, New Zealand and Korea. The findings from the study indicate that the connectedness with the dead is an important part of the participants' mental and social lives, and this postmortem relationship can be embodied through practising "memorial piety" and "memorial work". PMID- 30295567 TI - The self-reported perceptions of the repercussions of the disease and its treatments on daily life for young women with breast cancer and their partners. AB - PURPOSE: This study aimed to compare the self-reported perceptions of the repercussions of the disease and its treatments and emotional distress in young women with breast cancer and their partners. DESIGN: Cross-sectional study using self-reported questionnaires. SAMPLE: 491 couples in which women were aged <45 years when diagnosed with non-metastatic breast cancer in four different groups of treatment: during chemotherapy with or without Trastuzumab; under Trastuzumab with or without hormone therapy; during hormone therapy; and during the follow-up period. METHODS: Patients and partners completed a questionnaire assessing their self-reported perceptions of the disease and treatments (Patient YW-BCI and Partner YW-BCI for the partners) and their emotional distress (CESD; STAI). FINDINGS: Patients reported more difficulties than partners in the management of child(ren) and everyday life, body image and sexuality, negative affectivity about the disease and apprehension about the future, career management, and finances. While the difficulties were generally more marked in the chemotherapy and Trastuzumab groups than in the hormone therapy and follow-up groups, the negative affectivity about the disease and apprehension about the future was high in all four groups, especially in patients. The partners reported more difficulties in sharing with close relatives, and even more in those groups reflecting the latest treatment phases. No difference appeared between patients and partners in couple cohesion and deterioration of relationships with relatives. Partners were less anxious than patients but as depressed as them. CONCLUSIONS: Difficulties of patients and partners seem particularly severe in the early care pathway, maybe reflecting better adjustment in women under surveillance and their partners. A longitudinal study will substantiate this finding and enable a better identification of some explanatory processes of these differences and similarities in the daily self-reported repercussions of the disease throughout the cancer care pathway. Implications for psychosocial oncology: It seems important to support young women with breast cancer and their partners, as our results evidence distress in both and differences according to the type of treatment the woman is currently receiving. Healthcare providers need consistent methods to identify and respond to couples' distress and reduce significant disparities in support. PMID- 30295569 TI - The Power of Attention: Using Eye Gaze to Predict Other-Regarding and Moral Choices. AB - According to research studying the processes underlying decisions, a two-channel mechanism connects attention and choices: top-down and bottom-up processes. To identify the magnitude of each channel, we exogenously varied information intake by systematically interrupting participants' decision processes in Study 1 ( N = 116). Results showed that participants were more likely to choose a predetermined target option. Because selection effects limited the interpretation of the results, we used a sequential-presentation paradigm in Study 2 (preregistered, N = 100). To partial out bottom-up effects of attention on choices, in particular, we presented alternatives by mirroring the gaze patterns of autonomous decision makers. Results revealed that final fixations successfully predicted choices when experimentally manipulated (bottom up). Specifically, up to 11.32% of the link between attention and choices is driven by exogenously guided attention (1.19% change in choices overall), while the remaining variance is explained by top-down preference formation. PMID- 30295570 TI - Head Transplantation: The Immune System, Phantom Sensations, and the Integrated Mind. AB - The principal focus of this paper is to consider the implications of head and neck transplantation surgery on the issue of personal identity. To this end, it is noted that the immune system has not only been established to impose a level of self-identity on bodily cells, it has also been implicated in mental development and the regulation of mental state. In this it serves as a paradigm for the mind as the product of cephalic and extracephalic systems. The importance of bodily systems in identity is then discussed in relation to phantom tissue syndrome. The data strongly indicate that, even if surgically successful, head and neck transplantation will result in the loss of the continuity of personal identity. PMID- 30295571 TI - Performance shaping factors in the human error probability modification of human reliability analysis. AB - Human-induced accidents indicate the importance of human reliability analysis (HRA) in reducing and eliminating human errors, thus improving the reliability of human-machine systems. HRA takes both qualitative and quantitative approaches to determine the error of the operators and the contexts in which tasks are performed. To ensure that HRA results can objectively evaluate human error behaviors, the quantification of human error probability (HEP) is typically based on the qualitative analysis of human factors and task contexts and is further refined by performance shaping factors (PSFs). A good HEP process development includes the selection of PSFs, the evaluation of PSFs and the quantification strategy of HEP. A variety of HEP quantification analyses based on PSFs has been widely adopted in contemporary HRA studies. This work reviews three major quantification strategies used in HRA methods. Additionally, we generalize the modification of HEP with PSFs into a paradigm. PMID- 30295573 TI - Where there is inflammation, treatment may reduce disability progression - Commentary. PMID- 30295572 TI - Do Metabolic Traits, Vulnerability to Angling, or Capture Method Explain Boldness Variation in Eurasian Perch? AB - The pace-of-life syndrome (POLS) concept predicts that individuals with high baseline metabolic rates demonstrate high boldness, aggressiveness, and activity, especially in food acquisition, with associated relatively greater energy requirements. In fishes, these behaviors may increase individual vulnerability to angling. To test the predictions of the POLS concept, we quantified individual standard metabolic rate (SMR) and boldness in both wild-caught and hatchery reared Eurasian perch (Perca fluviatilis). We found both SMR and boldness to be repeatable traits but detected no correlation between them. Individual vulnerability to angling was assessed in the hatchery-reared perch, but we found no difference in boldness or SMR between vulnerable and nonvulnerable perch. Wild caught perch were ice fished using either natural or artificial bait, and we observed no differences in boldness or SMR with respect to bait type or capture order. Our findings do not support the predictions of the POLS concept and, consistent with earlier studies in perch, suggest that angling may not drive selection against boldness in this species.

PMID- 30295579 TI - A Dihydroflavonol-4-reductase-like Protein Interacts with NFR5 and Regulates Rhizobial Infection in Lotus japonicus. AB - In almost all symbiotic interactions between rhizobia and leguminous plants, host flavonoid-induced synthesis of Nod factors in rhizobia is required to initiate symbiotic response in plants. In this study, we found that Lotus japonicus Nod Factor Receptor 5 (LjNFR5) might directly regulate flavonoid biosynthesis during symbiotic interaction with rhizobia. A yeast two-hybrid analysis revealed that a dihydroflavonol-4-reductase-like protein (LjDFL1) interacts with LjNFR5. The interaction between MtDFL1 and MtNFP, two Medicago truncatula proteins with homology to LjDFL1 and LjNFR5, respectively, was also shown, suggesting that interaction between these two proteins might be conserved in different legumes. LjDFL1 was highly expressed in root hairs and the epidermal cells of root tips. Lotus ljdfl1 mutants and Medicago mtdfl1 mutants produced significantly fewer infection threads (ITs) than the wild-type control plants following rhizobial treatment. Furthermore, the roots of stable transgenic L. japonicus plants overexpressing LjDFL1 formed more ITs than control roots after exposure to rhizobia. These data indicated that LjDFL1 is a positive regulator of symbiotic signaling. However, the expression of LjDFL1 was suppressed by rhizobial treatment, suggesting that a negative feedback loop might be involved in regulation of the symbiotic response in L. japonicus. PMID- 30295580 TI - Subfamily-Specific Specialization of RGH1/MLA Immune Receptors in Wild Barley. AB - The barley disease resistance (R) gene locus mildew locus A (Mla) provides isolate-specific resistance against the powdery mildew fungus Blumeria graminis hordei and has been introgressed into modern cultivars from diverse germplasms, including the wild relative Hordeum spontaneum. Known Mla disease resistance specificities to B. graminis hordei appear to encode allelic variants of the R gene homolog 1 (RGH1) family of nucleotide-binding domain and leucine-rich repeat (NLR) proteins. Here, we sequenced and assembled the transcriptomes of 50 H. spontaneum accessions representing nine populations distributed throughout the Fertile Crescent. The assembled Mla transcripts exhibited rich sequence diversity, linked neither to geographic origin nor population structure, and could be grouped into two similar-sized subfamilies based on two major N-terminal coiled-coil (CC) signaling domains that are both capable of eliciting cell death. The presence of positively selected sites located mainly in the C-terminal leucine-rich repeats of both MLA subfamilies, together with the fact that both CC signaling domains mediate cell death, implies that the two subfamilies are actively maintained in the population. Unexpectedly, known MLA receptor variants that confer B. graminis hordei resistance belong exclusively to one subfamily. Thus, signaling domain divergence, potentially as adaptation to distinct pathogen populations, is an evolutionary signature of functional diversification of an immune receptor.

PMID- 30295582 TI - Black Ethnicity is Not a Risk Factor for Mortality or Graft Loss After Kidney Transplant in the United Kingdom. AB - OBJECTIVES: There are conflicting reports in the literature regarding outcomes after kidney transplant for patients of black ethnicity. To investigate further, we compared outcomes for black versus white kidney transplant recipients in a single UK transplant center. MATERIALS AND METHODS: We analyzed 1066 kidney transplant recipients (80 black patients, 986 white patients) within a single center cohort (2007-2017) in the United Kingdom, with cumulative 4446 patient year follow-up. Data were electronically extracted from the Department of Health Informatics database for every study recruit, with manual data linkage to the UK Transplant Registry (for graft survival, delayed graft function, and rejection data) and Office for National Statistics (for mortality data). Primary outcomes of interest were graft/patient survival. RESULTS: Black recipients have increased baseline risk profiles with longer wait times, difficulty in matching, worse HLA matching, more socioeconomic deprivation, and lower rates of living kidney donors. Postoperatively, black versus white recipients had increased risk for delayed graft function (34.3% vs 10.2%; P < .001), increased 1-year rejection (16.7% vs 7.3%; P = .012), higher 1-year creatinine levels (166 vs 138 mmol/L; P = .003), and longer posttransplant length of stay (14.5 vs 9.5 days; P = .020). Although black recipients did not have increased risk of death versus white recipients (10.0% vs 11.0%, respectively; P = .486), they did have increased risk for death-censored graft loss (23.8% vs 11.1%; P = .002). However, in an adjusted Cox regression model, black ethnicity was not associated with increased risk for death-censored graft loss (hazard ratio of 1.209, 95% confidence interval, 0.660 2.216; P = .539). CONCLUSIONS: Black kidney transplant recipients in the United Kingdom have increased risk of adverse graft-related outcomes due to high-risk baseline variables rather than their black ethnicity per se. PMID- 30295581 TI - The host stomatal density determines resistance to Septoria gentianae in Japanese gentian. AB - Plant stomata represent the main battlefield for host plants and the pathogens that enter plant tissues via stomata. Septoria spp., a group of ascomycete fungi, use host plant stomata for invasion and cause serious damage to agricultural plants. There is no evidence, however, showing the involvement of stomata in defense systems against Septoria infection. In this study, we isolated S. gentianae 20-35 (Sg20-35) from Gentiana triflora (G. triflora) showing gentian leaf blight disease symptoms in the field. Establishment of an infection system using gentian plants cultured in vitro enabled us to observe the Sg20-35 infection process and estimate its virulence in several gentian cultivars/lines. Sg20-35 also entered gentian tissues via stomata and showed increased virulence in G. triflora compared with G. scabra and their interspecific hybrid. Notably, the susceptibility of gentian cultivars to Sg20-35 was associated with their stomatal density on the adaxial but not abaxial leaf surface. Treatment of EPIDERMAL PATTERNING FACTOR 9 (EPFL9/STOMAGEN) peptides, a small secreted peptide controlling stomatal density in Arabidopsis thaliana, increased stomatal density on the adaxial side of gentian leaves as well. Consequently, treated plants showed enhanced susceptibility to Sg20-35. These results indicate that stomatal density on the adaxial leaf surface is one of the major factors determining the susceptibility of gentian cultivars to S. gentianae and suggest that stomatal density control may represent an effective strategy to confer Septoria resistance. PMID- 30295583 TI - Upper Extremity Compartment Syndrome Following Radial Artery Puncture in a Patient Undergoing Orthotopic Liver Transplant. AB - Acute compartment syndrome is the physiologic consequence of increasing pressures within an enclosed anatomic space; if left untreated, it can subsequently cause irreversible necrosis, nerve injury, and tissue damage. A number of iatrogenic causes have been reported in the literature; however, to the best of our knowledge, there are no prior reports of upper extremity compartment syndrome in orthotopic liver transplant following arterial line placement. Here, we report a 52-year-old male with a history of end-stage liver disease secondary to primary sclerosing cholangitis who presented for orthotopic liver transplant. A radial arterial line with 20-gauge catheter was placed atraumatically without complication. Intraoperatively, the patient developed severe coagulopathy. The cause was likely multifactorial, including dilution of factors from the massive blood loss during the dissection phase, a prolonged anhepatic period, and delayed graft function, resulting in decreased production of coagulation factors. This consumptive process likely subjected minor vascular injury to potential bleeding and caused a slow cumulative bleed into the right forearm, resulting in compartment syndrome. This case exemplifies the complications that can occur from arterial line placement in a liver transplant recipient who develops severe intraoperative coagulopathy. This can arguably be extrapolated to any situation caused by significant dilutional coagulopathy or a consumptive process, such as disseminated intravascular coagulation. As such, when large-volume blood transfusions are anticipated, we recommend that all central venous and arterial accesses be obtained under ultrasonographic guidance and that frequent extremity physical examinations should be performed at a minimum of every hour. Correcting the underlying coagulopathy is imperative to resolve ongoing bleeding, a high index of suspicion is warranted, and immediate diagnosis and therapy are integral to improving patient outcomes. PMID- 30295584 TI - Impact of Transplant Nephrectomy for Patient Survival Over the Past 15 Years: A Single-Center Study. AB - OBJECTIVES: How transplant nephrectomy affects patient survival after return to dialysis is unclear. Here, we compared patient survival after graft loss between patients with and without transplant nephrectomy. MATERIALS AND METHODS: We divided 171 patients who received transplant between 2000 and 2015 and had graft loss into 3 groups: 64 had graft failure left in situ (without nephrectomy), 51 had nephrectomy < 3 months posttransplant (early nephrectomy), and 56 patients had nephrectomy > 3 months posttransplant (late nephrectomy). The primary endpoint was patient survival. Risk factors for patient death were also analyzed. Secondary endpoints included relisting for transplant and immunosuppressive agent status. RESULTS: Patient survival rates at 1, 3, and 5 years posttransplant in those without nephrectomy, early nephrectomy, and late nephrectomy were 92.1% /90.5%/86.6%, 96.0%/89.7%/80.4%, and 100.0% /97.9%/ 95.6%, respectively. Rates in patients with early nephrectomy differed significantly from those with late nephrectomy (P = .005). On multivariate analysis, patient survival was affected by relisting for transplant (hazard ratio 0.17; 95% confidence interval, 0.06 0.41; P < .001) and graft survival duration (hazard ratio 0.36, 95% confidence interval, 0.13-0.93; P = .036). Relisting for transplant occurred in 46.9% of patients without nephrectomy, 56.9% of patients with early nephrectomy, and 51.8% of patients with late nephrectomy. Those with late nephrectomy took 14.7 months after graft loss to relist for transplant, with 7.8 months for those without nephrectomy (P = .039) and 6.3 months for those with early nephrectomy (P = .051). Only 10.9% of those without nephrectomy were immunosuppressive free, which was in contrast to 94.1% and 78.6% of those with early and late nephrectomy, respectively. CONCLUSIONS: After graft failure, patients without nephrectomy did not have inferior survival versus patients who received early or late nephrectomy. Graft survival time and relisting for transplant were associated with patient survival regardless of having transplant nephrectomy. PMID- 30295585 TI - Use of Rotational Thromboelastometry in Liver Transplantation Is Associated With Reduced Transfusion Requirements. AB - OBJECTIVES: Increased transfusion requirements in liver transplantation have been reported to be associated with worsened outcomes, more frequent reinterventions, and higher expenses. Anesthesiologists might counteract this through improved coagulation management. We evaluated the effects of rotational thromboelastometry on transfusion and coagulation product requirements and on outcome measurements. MATERIALS AND METHODS: Patients who were 14 years or older and who were undergoing liver transplant at Hannover Medical School between January 2005 and December 2009 were included in this retrospective analysis. Demographic, clinical, and laboratory data, use of rotational thromboelastometry, intraoperative need for blood or coagulation products and antifibrinolytic substances, and clinical course were recorded. Correlations were examined using appropriate statistical tests. RESULTS: Our study included 413 patients. Use of rotational thromboelastometry was associated with less frequent intraoperative administration of red blood cell concentrates, fresh frozen plasma, platelet concentrates, prothrombin complex concentrates, and antithrombin concentrates (all P < .05). In addition, univariate and multivariate tests showed that rotational thromboelastometry was correlated with decreased need for red blood cell concentrates and fresh frozen plasma (all P < .05). Intraoperative administration rates of antifibrinolytic substances and fibrinogen concentrate were significantly increased in patients who received rotational thromboelastometry monitoring (both P < .05). However, use of rotational thromboelastometry was not associated with massive transfusion rates (> 10 units vs less), clinical outcome, or length of stay in the intensive care unit (all P > .05). CONCLUSIONS: Use of rotational thromboelastometry during liver transplant may reduce the need for intraoperative transfusion and coagulation products. Relevant effects of rotational thromboelastometry on patient outcomes or lengths of stay in the intensive care unit could not be ascertained. However, readjustment of therapeutic thresholds may improve the clinical impact. PMID- 30295586 TI - Incidence of Post-Liver Transplant Hepatic Dysfunction After Sustained Virologic Response Following Direct-Acting Anti-Hepatitis C Therapy. AB - OBJECTIVES: Newly developed, direct-acting antiviral therapy is effective in over 90% of cases to eradicate hepatitis C virus infection. Direct-acting antiviral therapy is also effective in liver transplant recipients with recurrent hepatitis C virus infection. However, hepatic function after sustained virologic response in transplant recipients is unknown. Here, we aimed to uncover the incidence of hepatic dysfunction in this patient group at our center. MATERIALS AND METHODS: Our study included 40 consecutive (January 2014 to February 2016) and compliant posttransplant recipients who achieved sustained viral response from direct acting antiviral therapy. Patients were investigated for incidence and causes of hepatic dysfunction. RESULTS: In our patient group, 4 (10%) experienced hepatic dysfunction with stable baseline immunosuppression, with 2 having drastic increases in alanine aminotransferase at 15 and 32 weeks after direct-acting antiviral therapy. Biopsies showed hepatitis, and both patients were treated with hydrocortisone, which increased their baseline immunosuppression. The 3rd patient had an increase in bilirubin at 21 weeks posttherapy, with biopsy showing macrovascular steatosis. The 4th patient had a rapid increase in bilirubin at 7 weeks after direct-acting antiviral therapy, with biopsy showing significant duct loss. CONCLUSIONS: During the study period, 10% of patients experienced hepatic dysfunction after sustained viral response. Presumed causative factors included partial immune reconstitution and nonalcoholic fatty liver disease. PMID- 30295587 TI - A Single-Center Experience With Hematopoietic Stem Cell Transplantation for Pediatric Acute Lymphoblastic Leukemia: A Modest Pitch for Non-Total Body Irradiation Conditioning Regimens. AB - OBJECTIVES: Allogeneic hematopoietic stem cell transplantation has been used for several decades to treat patients with acute lymphoblastic leukemia. Total body irradiation has been promoted as an important component of conditioning regimens for this process; however, recent reports of chemotherapy-based conditioning regimens have shown comparable outcomes. MATERIALS AND METHODS: We report our experience with radiation-free conditioning using busulfan and cyclophosphamide in 127 pediatric patients with acute lymphoblastic leukemia who were treated between 1997 and 2014. The median age was 11 years (range, < 1 to 15 y), 70% of patients were male, 81.1% received transplants from HLA-matched siblings, 83% received peripheral blood stem cells, 41% were in second complete remission at the time of transplant, and 83% had B-lineage immunophenotype. RESULTS: In patients who were in complete remission at the time of transplant, 5-year overall survival, leukemia-free survival, and relapse rates were 62.48% (95% confidence interval, 52.29-71.09%), 49.43% (95% confidence interval, 39.57-58.53%), and 45.64% (95% confidence interval, 35.85-54.88%), respectively. We observed significant differences between outcomes in patients by time of transplant, presence of chronic graft-versus-host disease, and remission status. CONCLUSIONS: Our relapse rates were comparable to those shown in recent studies, although the transplant-related mortality rate was lower. The results of our study showed that a busulfan/cyclophosphamide conditioning regimen has acceptable outcomes without the undesirable adverse effects of total body irradiation, particularly in pediatric patients. Large multicenter studies are needed to assess less toxic conditioning regimens with fewer adverse effects in these patients. PMID- 30295588 TI - N-Acetylcysteine and Benfotiamine Protect Autotransplanted Ovarian Tissue From Ischemia-Reperfusion Injury: An Experimental Study. AB - OBJECTIVES: This study aimed to compare the effects of N-acetylcysteine and benfotiamine in protection of ovarian tissue from ischemia caused by slow neovascularization injury due to intraperitoneal ovarian autotransplant in rats. MATERIALS AND METHODS: Twenty-eight female rats were divided into 4 groups, each containing 7 rats. Group 1 only had the abdomen opened and closed, group 2 was the transplant-only group, group 3 received benfotiamine for 3 weeks starting 1 day before the transplant procedure, and group 4 received N-acetylcysteine for 3 weeks starting 1 day before the transplant procedure. At the end of the experimental period, malondialdehyde levels in ovarian tissues together with the apoptosis and fibrosis, proliferating cell nuclear antigen and vascular endothelial growth factor immunoreactivity, and ovarian reserves were investigated. RESULTS: Apoptosis was significantly increased in group 2 animals. Primordial follicle count was higher in groups 3 and 4 than in group 2. Vascular endothelial growth factor immunoreactivity was decreased in groups 3 and 4 compared with group 2. Proliferating cell nuclear antigen immunoreactivity was reduced in the secondary follicles in all transplant groups. CONCLUSIONS: In autologous intraperitoneal ovarian transplant, both benfotiamine and N acetylcysteine are equal and effective agents in protection of ovarian tissue against ischemic injury.

This study explores the strength of the relationship between Karnofsky Performance Status scores and objective measures of frailty. MATERIALS AND METHODS: This observational study includes 136 adult, first-time liver transplant recipients at UMass Memorial (2006-2015) who had 2 abdominal computed tomography scans available (at <= 90 days pretransplant and >= 7 days before that). We analyzed the relationship between Karnofsky Performance Status and muscle wasting using absolute and change in psoas muscle size and quality pretransplant. RESULTS: The mean age was 55 years, mean Model for End-Stage Liver Disease was 22, and 34% of patients were women. In the study group, 50% of patients had sarcopenia pretransplant and 71.3% demonstrated declined lean psoas area at an average rate of 11% per month. Patients who experienced muscle wasting at a rate of >= 1% per month had 2.83 times the risk (95% confidence interval, 1.18-6.80) of being severely impaired/disabled pretransplant. The risk increased by 2.32-fold (95% confidence interval, 1.44-3.75) for every standard deviation decrease in pretransplant lean psoas area. CONCLUSIONS: Provider-assessed physical health status moderately correlates with objective measures of frailty.

AB - CLINICIAN'S CAPSULE What is known about the topic? Oral anticoagulation (OAC) reduces stroke risk in patients with atrial fibrillation or flutter; however, initiation rates in patients discharged from the ED are low. What did this study ask? Can a simple quality improvement intervention increase the initiation of appropriate OAC in the ED? What did this study find? The rate of OAC initiation was increased by 8.5%. Why does this study matter to clinicians? This simple intervention is transferrable and therefore can improve patient care.

AB - PURPOSE OF THE STUDY Fragility fractures of the pelvic ring in the elderly population are a serious problem in orthopaedics. The treatment options range from conservative treatment to diverse operative options. We present a balloon guided new technique of implanting cement augmented screws aiming at improved implant anchorage and reduced cement leakage. MATERIAL AND METHODS We describe a new technique of balloon- guided cement augmented iliosacral screws. After the balloon has been insufflated and contrast medium has been instillated for leakage detection, iliosacral screws can safely be placed with a relevant cement depot. RESULTS All patients (n = 8) treated in this way were allowed to weight bear on both legs and mobilisation was tolerated the next day after surgery. In the post operative controls including X-ray and CT scan we noticed no cement leakage. Pain level as measured by the visual analog scale was significantly reduced to pre- surgery (mean 7.6 pre-operatively, mean 2.5 postoperatively). In addition pain medication could be reduced gradually soon after surgery. CONCLUSIONS The described procedure to address fragility fractures of the pelvic ring is a safe and easy to handle method. There are three advantages: First the osteoporotic S1 vertebral body can by stabilised by the amount of cement; second the cement leakage can be prevented by the balloon-compaction of the cancellous bone and the possibility to control the created cavity with contrast medium; third the bone - screw interface is much stronger compared to other procedures and is biomechanically superior against vertical shear stress. In contrast to sacroplasty, the cement application is guided by the previous use of a balloon. Key words:pelvic ring, fragility fracture, osteoporosis, elderly.

AB - PURPOSE OF THE STUDY The Growth Guidance System (GGS) represent a relatively new alternative to the traditional growing systems used for the treatment of early onset scoliosis. Ranking among the main aims of this surgical treatment is a three-dimensional correction of the deformity, maintenance of spinal growth and postponement of the necessity of final treatment by spondylodesis. MATERIAL AND METHODS Our study retrospectively evaluates the results of surgical correction in a group of 35 patients treated by GGS technique. The group consisted of patients with idiopathic, neuromuscular and syndromic spine deformity with the average age of 8 years and 2 months at the time of the surgery. The time of the follow-up is 3 years and 5 months on average. We evaluated the correction of the curve itself, the growth of the spine measured in the thoracic and lumbar part separately, and the growth of the trunk as a whole in the mentioned range on X-ray pictures. RESULTS The average correction of the scoliotic curve was 67%, from 75 preoperative degrees to 20 postoperative degrees. After the first operation 11% elongation of the trunk (from 321 mm to 356 mm) was reached, the thoracic spine was elongated by 10% (from 196 to 217 mm) and the lumbar spine was elongated by 11% (from 125 to 139 mm). The elongation of the trunk by 16% (from 322 to 375 mm) was observed in the cohort of patients with two years postoperative follow-up (21 patients). The total protraction of the trunk by 21% (from 318 to 386 mm) was reached in patients treated by definitive fusion (7 patients). DISCUSSION There is a very low number of studies analysing the long-term clinical results with the use of GGS. The first pilot results indicate that it is a technique allowing to achieve at least comparable results in correction of frontal plane compared with the distraction type of instrumentations. A negative aspect of this method is the abrasion of metal followed by metallosis. The new types of fixation screws enable more effective sliding of rods, maintenance of continuity of body grow by the shifting of rods as well as lower abrasion of the instrumentation. CONCLUSIONS The main advantage of GGS is the limited continuous growth of the spine, partial three-dimensional correction of the deformity, minimisation of inevitable reoperations under general anaesthesia and the possibility to quit a brace.

AB - PURPOSE OF THE STUDY This original paper aims to present the conclusions of the prospective study evaluating the clinical results of anatomical all-inside ACL reconstruction using quadrupled semitendinosustendon graft with posteromedial harvest using suspensory fixation by Tightrope implants at the follow-up of at least 12 months. MATERIAL AND METHODS The prospective study included a total of 119 patients (74 men/39 women) with the mean age of 28.3 (18-52) years, in whom demographic data was collected and a clinical examination was performed. The patients satisfying the "inclusion" and "exclusion" criteria were enrolled in the study and subsequently underwent the same, aforementioned surgical procedure performed by a single surgeon. Preoperatively and at a minimum 12-month follow-up the following subjective criteria were evaluated using the Lysholm and IKDC subjective scores and the Visual Analogue Scale (VAS) (0-10). The objective parameters comprised the side-to-side difference in anterior knee laxity assessed by Genourob arthrometer with an applied pressure of 134 and 250 N, anterior drawer test, and the pivot shift test. The occurrence of graft failure, complications and return to pre-injury sport levels were monitored. The obtained data was statistically evaluated at the statistical significance level of 0.05. RESULTS A total of 89 patients were assessed at the follow-up of at least 12 months after the surgery. The median Lysholm score increased over time from 58.7 preoperatively to 94.2 postoperatively (p < 0.05) and the IKDC subjective score went up from 46.3 to 91.4 (p < 0.05). The median postoperative VAS kept decreasing from 7.3 (Day 2), 5.1 (Day 14), 3.1 (Week 6), 1.2 (Month 6) to 0.3 at 12 months after the surgical procedure. Preoperatively, the results were significantly positive (i.e. C, D) in 52.8% (C) and 21.4% (D), whereas postoperatively the results of the PST were significantly positive only in 4%. Therefore, the surgical procedure was conducive to a statistically significant decrease in rotational knee laxity over time (p < 0.05). The median side-to-side difference in anterior laxity of the operated knee objectively assessed by GNRB arthrometer with the applied pressure of 134 N was 4.2 mm (3.1-6.8) as against the postoperative 1.2 mm (0.4-2.1) and with the applied pressure of 250 N it was 6.2 mm (4.6-8.7) prior to the surgical procedure versus 2.4 mm (1.6-3.5) postoperatively. That concerned a statistically significant decrease of postoperative side-to-side difference in anterior laxity of the operated knee at both the measured pressures (p < 0.05). The graft failed in 3 patients only (3.4%), no major complications associated with the surgical procedure were observed and 62 of the evaluated patients (69.6%) were able to return to the pre injury level of sport within one year after the surgery. DISCUSSION When comparing the results obtained by our study with the conclusions of clinical studies carried out by other authors and evaluating similar clinical parameters with the identical surgical technique applied, it is obvious that in our group of patients we achieved similar clinical results as the other authors from abroad. CONCLUSIONS The results of our study showed that the all-inside ACL anatomical reconstruction using quadrupled semitendinosus tendon graft with posteromedial harvest with suspensory fixation by Tightrope implants at one year after the surgery bring very good subjective as well as objective clinical results and minimum complications.

PMID- 30295595 TI - Use of Mother-Child Screws in the Treatment of Coronoid Fractures in Terrible Triad Injury of the Elbow. AB - PURPOSE OF THE STUDY This study aims to analyze the clinical and radiographic outcomes of a consecutive series of 18 patients with terrible triad injury. The coronoid fractures of these patients were repaired using Mother-Child screw (MCS). MATERIAL AND METHODS Twelve men and six women (mean age: 47.2 years) with terrible triad injury of the elbow were followed up for a mean of 17.6 months (range: 13-42 months). Surgical treatment consisted of open reduction and internal fixation of coronoid fractures with MCS, radial head fracture with MCS (Mason type II, n = 10), or mini-plate (Mason type III, n = 3). Furthermore, all underwent lateral collateral ligament repair (n = 9, 100%), and in cases of persistent instability, medial collateral ligament repair was performed (n = 3, 33%). RESULTS At last follow-up, average arc of ulnohumeral motion was 130 degrees (range: 65 degrees to 150 degrees ), average arc of forearm rotation was 148 degrees (range: 100 degrees -160 degrees ), mean Disabilities of the Arm, Shoulder and Hand (DASH) score was 7.1 (range: 0-28.5), and mean Mayo Elbow Performance Score (MEPS) was 92 (range: 70-100). According to the Mayo Elbow Performance Index (MEPI), 10 patients were excellent in, seven patients were good, and one patient was fair. All patients had a stable elbow. No secondary coronoid fragment dislocation or implant failures was reported. Fracture healing was observed in all patients. CONCLUSIONS This study shows that coronoid fracture treatment with MCS may be a new, effective and easy therapeutic option in terrible triad injury.

AB - PURPOSE OF THE STUDY Non-osseous giant cell tumors are locally aggressive tumors arising around joints. They are commonly located around synovial joints such as wrist and knee and occasionally cause mechanical symptoms. MATERIAL AND METHODS This retrospective case series includes 7 patients operated due to intraarticular lesion. The mean age of the patients was 28.7 (range 22-37) years. Mean follow-up period was 12 months. RESULTS All patients underwent arthroscopic debridement. They were followed monthly with clinical examination and magnetic resonance imaging (MRI) was obtained at third month for all patients. Patients were contacted through phone call and evaluated with the WOMAC score retrospectively. No recurrence was detected in any patient. CONCLUSIONS Arthroscopic debridement is a safe surgical technique that may replace open surgery in the treatment of intraarticular tendinous giant cell tumors.

AB - PURPOSE OF THE STUDY The locked nailing of diaphyseal fractures of the tibia currently represents a method of choice for treating the closed diaphyseal fractures, some of the tibial metaphyseal fractures and open tibial diaphyseal fractures classified as grade I and II according to Gustilo-Anderson (GA) classification. The suprapatellar (SP) approach is an alternative technique of insertion of the nail in semi-extension of the lower extremity with easier reduction, namely of multiple fractures and proximal diaphyseal fractures of the tibia in particular. This study aims to evaluate the group of patients in whom the suprapatellar approach was used and who were followed up for the period of at least 12 months. MATERIAL AND METHODS The prospective study included 55 cases of osteosynthesis of diaphyseal fractures of the tibia with the surgery performed in the period from January 2013 to June 2015, of which in 53 patients (17 women and 36 men) with the mean age of 49.6+/- 16.7 years the ETN nail by DePuy Synthes (r) was inserted through a suprapatellar approach. In 38 cases (70.1%) an isolated trauma was involved, 15 patients (29.9%) were treated for multiple injuries or polytrauma. In nine cases (17%) it was an open fracture (2times - GA grade I, 7times - GA grade II). A multiple fracture or a fracture of the proximal third was recorded in 19 cases (34.5%). The functional and radiological results of the treatment were assessed prospectively at 12 months after the surgery using the Lysholm (LS) score. RESULTS The final functional results were successfully assessed in 49 performed osteosyntheses (89.1%). The mean duration of surgery was 72.7+/- 19.57 min (40-140 min, median 65 min). A total of 48 (98%) fractures healed by primary intention. In five cases (10.2%) a delayed healing occurred and in one case (2 %) non-union was reported, requiring a revision surgery. In three cases (6.1%) complete implant was removed (twice by SP and once by IP approach). The mean Lysholm score was 93.4 +/- 8.39 points (59-100 points, median score of 95 points). An excellent or a good result was observed in 45 patients (91.8%), a satisfactory result in three patients (6.2%), and a poor result in one patient (2%). A statistically significant correlation (p = 0.006) between the LS score values and the age of the patients was confirmed. In patients up to 60 years of age the LS score was 96.2 +/- 4.51 points (89-100, median 96), at the age of more than 60 years it was 86.9 +/- 11.46 (59-100, median 89). CONCLUSIONS The suprapatellar approach in treating the tibial diaphyseal fractures represents a safe alternative nail insertion technique. If an appropriate surgical technique is applied, the risks inherent in this approach are negligible. The approach allows for an easy reduction of challenging fractures of the proximal third diaphyseal fracture of the tibia and multiple fractures of the tibia and facilitates an easy check of the axial position of the extremity. The functional results of the knee joint are comparable to those achieved with the infrapatellar nailing technique. The final LS score correlates with the age of the patients.

AB - PURPOSE OF THE STUDY This study aims to evaluate the results of patients treated by proximal row carpectomy at a follow-up of at least 5 years after the surgery. MATERIAL AND METHODS A total of 25 patients were treated by proximal row carpectomy for degenerative changes of the wrist as a consequence of the previous trauma or avascular necrosis of the lunate bone, of whom 21 patients underwent a follow-up examination at least 5 years postoperatively. Proximal row carpectomy was indicated in 15 patients for SLAC wrist, in 4 patients for avascular necrosis of the lunate bone, in 1 patient for SNAC wrist, and in 1 patient for inveterate dislocation of the wrist. The follow-up clinical and radiological examinations were performed at least 5 years after the surgery. The range of wrist motion, grip strength, presence of pain at rest or pain under loads, total clinical score according to the Green and O'Brien scoring system, patient satisfaction with the outcome of surgery were assessed. By fluoroscopy the range of wrist motion, degenerative changes of the radiocapitate joint, and translation of the capitate bone with respect to the distal radius were evaluated. RESULTS Postoperative improvements in the range of motion and grip strength were confirmed. Also, the pain relief at rest and under loads was achieved. Five years after the surgery, most of the patients (85.6%) reported an overall improvement. The total clinical score according to the Green and O'Brien scoring system improved from 35.8 preoperatively to 63.1 postoperatively. DISCUSSION The advantage of this procedure is a low percentage of complications, relative technical simplicity, maintenance of functional motion of the wrist, satisfactory grip strength, and pain relief. There are no complications related to the implant, no risk of a non union. CONCLUSIONS As shown by our results obtained 5 years after the surgery as well as the published data, in the indicated cases the proximal row carpectomy is an appropriate surgical technique to treat the degenerative changes of the wrist. In most of the patients, favourable functional results and pain relief can be expected.

PMID- 30295599 TI - [Interposition and Suspension Arthroplasty of Carpometacarpal Joint of the Thumb Using the TIE-IN Implant]. AB - PURPOSE OF THE STUDY The aim of the study was to present the surgical technique combining the interposition and suspension arthroplasty using the TIE-IN implant as a treatment option for advanced symptomatic to final stage rhizarthrosis. MATERIAL AND METHODS Since 2015 we have performed the interposition arthroplasty combined with suspension arthroplasty using the TIE-IN implant in 12 patients, mostly indicated for stage IV rhizarthrosis. In two cases stage III rhizarthrosis with concomitant trapezium destruction was present. In two other cases the patients suffered from secondary osteoarthrosis associated with rheumatoid arthritis. Pain under loads was present in all the patients, of whom in 10 patients also the pain at rest occurred. Preoperatively, a total of 10 patients showed subluxation of the first carpometacarpal joint of 50% of the articular surface width. The ratio between the dominant and non-dominant extremity was 1:1. As a part of the evaluation, correlation was established between the preoperative findings and the postoperative results at 3 months follow-up. The examination included the assessment of pain intensity by VAS scale, the range of motion measurement - by Kapandji thumb opposition test, handgrip strength test and functional evaluation using the scoring systems - DASH score, modified DASH score for thumb, and modified Wrightington score. RESULTS No intraoperative or postoperative complications such as infection, complex regional pain syndrome, implant failure or failed surgical procedure were reported in the given group of patients. The pain at rest ceased in all 12 patients. The VAS pain intensity score improved from the preoperative average of 5.8 to 0.8 postoperatively. The range of motion in all the patients with stage IV rhizarthrosis substantially improved. The average Kapandji thumb opposition score increased from 6.9 preoperatively to 9.5 postoperatively. DISCUSSION There are multiple surgical treatment options for advanced rhizarthrosis. Apart from the combination of interposition and suspension arthroplasty referred to above, it is trapeziometacarpal (TMC) arthrodesis on the one hand and carpometacarpal joint total arthroplasty on the other hand. The arthrodesis continues to be a fairly frequently used procedure, despite the final limitation of thumb movement. It is because of this loss of fine motor function why it is not the preferred technique for treating advanced rhizarthrosis at our department. On the very contrary, the total replacement of the TMC joint is at our department as well as at many other departments the treatment of choice for advanced symptomatic rhizarthrosis since in conservative resection of the articular surfaces the biomechanics of the carpometacarpal joint of the thumb is preserved. As an outcome, this technique combines the advantages of other surgical methods by ensuring full painless range of motion and strength of the joint as opposed to other techniques, which mostly result either in a limited movement, or in a loss of grip strength. There is a whole range of resection arthroplasty techniques available. From simple trapeziectomy, which leads to the radial column collapse and ultimately to a major functional deficit, up to various interposition or suspension arthroplasty techniques with the resulting range of motion, stability and thus grip strength depending on the technique applied. CONCLUSIONS By applying the combination of the interposition and suspension arthroplasty of the carpometacarpal joint of the thumb using the TIE-IN implant we preserve the length of the thumb, its stability, and thus achieve the recovery of adequate thumb range of motion and grip strength. Our conclusions are in correlation with the results obtained at reference centres. Key words:rhizarthrosis, trapeziometacarpal prosthesis, arthroplasty, trapezium implant. PMID- 30295600 TI - [Short-Term Results of the Carpometacarpal Joint Arthroplasty Using the Ivory(r) Prosthesis]. AB - PURPOSE OF THE STUDY Trapeziometacarpal osteoarthritis affects primarily postmenopausal middle-aged and older women. Total joint replacement is one of the surgical treatment options for symptomatic advanced degenerative changes of the carpometacarpal joint. This study aims to evaluate the short-term functional and radiological results of the Ivory (r) prosthesis with the minimum followup period of three years after the surgery. MATERIAL AND METHODS Presented are the results of 48 total trapeziometacarpal joint replacements in the group of 40 patients composed of 36 women and 4 men. The age of patients ranges from 41 to 75 years (median 56 years), with the ratio between the dominant and non-dominant upper extremity 23:25. The follow-up period ranged from 36 to 63 months (median 52 months). The surgery was indicated in patients with symptomatic trapeziometacarpal arthrosis of stage II, III and early stage IV according to Eaton-Glickel once the conservative therapy had failed. In all the patients, the evaluation of the function and pain of the operated joint by DASH score, the range of motion -thumb opposition by Kapandji score were carried out at regular intervals pre- and postoperatively, the radiological evaluation of the stage of degenerative joint condition was done preoperatively, whereas the position of the implant and the lengthening of the first column of the finger were assessed postoperatively. RESULTS Subjectively, the patients were satisfied with the result of the surgery. After the joint replacement, in 65% of cases the patients reported full satisfaction with no difficulties present, in 31% of cases the patients suffered from pain during loading, in 4% of cases the patients reported also occasional pain at rest. Postoperatively, the total DASH score values decreased from the mean preoperative value of 52.79 to 10.4 points at a three year follow-up. The average value of pain dropped from 3.46 to 1.44 points 3 years after the surgery. The average range of motion - thumb opposition by Kapandji score increased from 8.57/10 to 9.85/10 one year after the surgery. The difference between the values of average increase in length of the first column of the finger was 0.14 mm in favour of the sub-group of symptomatic cases. In the evaluated group, the need for revision was determined in 4 implants. In 1case for aseptic loosening of the cup and three times for dislocation. After 36 months, 47 of 48 implants were in situ, the overall three-year survival was achieved in 97.9%. The most frequent postoperative complication was the occurrence of De Quervain s tenosynovitis (10%). DISCUSSION Currently, most of the newer types of modular uncemented hydroxyapatite-coated total "ball and socket" joint replacements present acceptable medium-term, and in some cases even long-term, results regarding the survival. The most pressing issue continues to be the survival of implants, particularly the failure of the trapezial component and the associated risk of revision surgery. Good postoperative results can be achieved by accurate indication, carefully applied cup implant and good postoperative cooperation of patients. The complementary study did not confirm that the lengthening of the thumb causes the postoperative development of De Quervain s tenosynovitis. CONCLUSIONS The uncemented first carpometacarpal joint total replacement using the Ivory (r) prosthesis brings about very good shortterm functional and radiological results, with no occurrence of early aseptic loosening of the implant.

AB - PURPOSE OF THE STUDY The postoperative delirium is a frequent, oftentimes underestimated complication of total hip arthroplasty. Its occurrence is reported to be between 10% and 50%. The postoperative delirium increases mortality, the length of hospital stay and leads to worse functional results. Even though there is evidence of efficiency of preventive measures and effectiveness of treatment interventions, inadequate attention has been paid so far to this serious complication related to inpatient hospital care. This paper aimed to determine the incidence of cognitive function impairment in relation to the total hip replacement, to determine the influence of the defined parameters on changes in cognitive functions and to draft practice guidelines for the care of patients after a total hip replacement in the framework of prevention and early detection of changes in cognition of patients after total hip replacement. MATERIAL AND METHODS Prospective observational descriptive study, the evaluated parameters included: type of anaesthesia, duration of surgical procedure (operation), type of analgesia, O2 saturation, haemoglobin levels, changes in the ionogram, body temperature, presence of concomitant diseases, polypragmasia, abuse, level of self-sufficiency of patients evaluated by ADL. In order to obtain the data, the Mini Mental State Examination (MMSE), the Abbreviated Mental Test Score (AMTS), Recall and naming test, and the Activities of Daily Living Test (ADL) were used. The monitored group of patients included a total of 116 persons, of whom 68 men and 48 women. The mean age was 71.16 years; the range from 65 to 86 years; median - 72.36 years. RESULTS A statistically significant dependence was revealed between the change in cognitive functions and all the monitored parameters, except for the haemoglobin levels after 120 hours postoperatively, ion levels after 120 hours and sex by the 10-point Mini Mental Test score. A statistically significant dependence was revealed between the change in cognitive functions and 02 saturation, ion levels, elevated body temperature after 120 hours postoperatively, age, diabetes, polypragmasia and in correlation with the ADL 120 hours postoperatively by the MMSE test. A statistically significant dependence was revealed between the change in cognitive functions and all the monitored parameters, except for anaesthesia and analgesia, haemoglobin levels after 24 and 120 hours, ion levels after 120 hours, renal insufficiency and in correlation with the ADL after 24 hours by the "Recall and naming" test. DISCUSSION The correlation between delirium and long-term cognition impairment was described by several studies. Both the recent literature and our study clearly indicate a correlation between the postoperative cognitive impairment on the one hand and polypragmasia, age, presence of concomitant diseases on the other hand. In some parameters such as the sex of the patient its influence was not clearly established by the relevant literature or our study. The perioperative factors influencing the onset of delirium referred to in literature are anaesthesia and its duration. Our study reveals the correlation between the anaesthesia and the onset of cognitive impairment when evaluated by the Abbreviated Mental Test Score. As regards the monitored postoperative parameters, the influence of postoperative hyposaturation, decreased haemoglobin level, changes in ionogram, elevated body temperature, lower self-sufficiency of the patient was established. Also our study shows the correlation between the change in the aforementioned parameters and the cognitive impairment, even though not quite clearly in all the parameters. The most sensitive evaluation tool turned out to be the Abbreviated Mental Test Score. CONCLUSIONS Our study clearly showed that a highly sensitive test to detect the current changes in cognition in a short-term horizon is the Abbreviated Mental Test Score. Based on the statistically significant factors determining the onset of the change in cognition that we had revealed, we elaborated a clearly arranged scheme of identified risk factors and interventions for the prevention and early identification of the onset of changes in cognitive functions and potential delirium.

AB - PURPOSE OF THE STUDY Outcome analysis of penetrating cardiac and great vessels injury within the 15-year existence of the cardiac surgery service as a part of the major trauma centre of the University Hospital Olomouc MATERIAL AND METHODS Retrospective analysis of a group of a total of 16 patients who underwent a surgery for penetrating cardiac and great vessels injury since II/2002 to XI/2016. The dominant causes of penetrating trauma were stab injuries (15 patients, 94%), in one patient only (6%) it was a gunshot injury. The mean age of the patients included in the group was 42.9 +/- 16.1 years, with men significantly prevailing (13 patients, 81%). A total of 7 injured persons (44%) were haemodynamically stable when admitted, 9 injured persons (56%) were unstable or in critical condition. The average transfer distance was 48.8 +/- 34.5 km; the injured were admitted on average 115.9 +/- 154.8 minutes after being injured. Preoperatively, all the injured suffered from pericardial effusion (>5 mm) confirmed by TTE (81%) or CTA (19%). In 4 patients (25%) pericardial drainage for cardiac tamponade was performed before surgery. RESULTS All the penetrating cardiac and great vessels injuries were repaired by cardiac surgeon, in one case only (6%) the extracorporeal circulation support was used. The injury of coronary arteries was in one case managed by CABG and in the other case by ligation of the peripheral part of the coronary artery. In 4 patients (25%) also a penetrating injury of other organs was simultaneously managed. The mean ICU stay reached 85.8 +/- 91.9 hours, on average 5.6 +/- 9.3 units of red blood cells were administered during the in-hospital stay which lasted on average 7.1 +/- 2.4 days. In the group a nonsignificant increase of left ventricular ejection fraction (44.1 +/- 4.7 vs. 49.3 +/- 3.2, p = 0.882) was reported at discharge of the injured patients. One patient died on the 78 th day of hypoxic brain damage (6% three month mortality). The long-term survival analysis showed 94% one-year and 88% five-year cumulative survival in the group. DISCUSSION The incidence of the penetrating cardiac and great vessels injury is directly dependent on the crime level in the respective countries and regions. A cardiac arrest, severe hemodynamic instability, unconsciousness, serious concomitant injury, gunshot injury, multiple or atrial injury represent independent predictors of death in these injuries. The total three-month mortality in penetrating cardiac and great vessels injury ranges from 18 to 42%, the presence of vital signs at the time of hospital admission is associated with 78-92% probability of survival. The surviving patients show excellent long-term results with the exception of those who suffered a severe damage to valve apparatus or with significantly depressed left ventricular function. CONCLUSIONS Our experience proves a high survival rate of patients with penetrating cardiac and great vessels injury. The centralisation of the care into the major trauma centre with a cardiac surgery background, a unified treatment algorithm, and a vital interdisciplinary cooperation are the key goal of successful management of these injuries.

These injuries are coupled with both a high energy mechanism (combat injury, motor vehicle accidents) and with foreign body impalement. The treatment is individual, laparotomy with penetrating wound exploration is indicated, osteosynthesis is performed in case of grossly displaced fractures, in an unstable injury to the posterior pelvic ring, and urgently in case of a neurological injury. The case report describes a 14-year-old girl with a left-sided anterior penetrating sacral injury at the level of S2/S3, who was injured during a bicycle accident (impalement on handlebars). The emergent laparotomy was performed first to treat the lesion of the sigmoid mesocolon. After 16 days the patient underwent the second operation, when open fragment reposition and sacral bone suture were performed. Both the sacral fracture and soft tissues were healed in 6 weeks. The patient was fully weight bearing and without pain. Key words:pediatric sacral fracture, penetration, treatment.

AB - TOPBP1 and its fission yeast homologueRad4, are critical players in a range of DNA replication, repair and damage signalling processes. They are composed of multiple BRCT domains, some of which bind phosphorylated motifs in other proteins. They thus act as multi-point adaptors bringing proteins together into functional combinations, dependent on post-translational modifications downstream of cell cycle and DNA damage signals. We have now structurally and/or biochemically characterised a sufficient number of high-affinity complexes for the conserved N-terminal region of TOPBP1 and Rad4 with diverse phospho-ligands, including human RAD9 and Treslin, and Schizosaccharomyces pombe Crb2 and Sld3, to define the determinants of BRCT domain specificity. We use this to identify and characterise previously unknown phosphorylation-dependent TOPBP1/Rad4-binding motifs in human RHNO1 and the fission yeast homologue of MDC1, Mdb1. These results provide important insights into how multiple BRCT domains within TOPBP1/Rad4 achieve selective and combinatorial binding of their multiple partner proteins.

AB - Cyclic G/AMP synthase (cGAS) initiates type-1 interferon responses against cytosolic double-stranded (ds)DNA, which range from antiviral gene expression to apoptosis. The mechanism by which cGAS shapes this diverse signaling landscape remains poorly defined. We find that substrate-binding and dsDNA length-dependent binding are coupled to the intrinsic dimerization equilibrium of cGAS, with its N terminal domain potentiating dimerization. Notably, increasing the dimeric fraction by raising cGAS and substrate concentrations diminishes duplex length dependent activation, but does not negate the requirement for dsDNA. These results demonstrate that reaction context dictates the duplex length dependence, reconciling competing claims on the role of dsDNA length in cGAS activation. Overall, our study reveals how ligand-mediated allostery positions cGAS in standby, ready to tune its signaling pathway in a switch-like fashion. PMID- 30295608 TI - A Wearable Multifunctional Pulse Monitor using Thermosensation-based Flexible Sensors. AB - OBJECTIVE: This study proposes a novel wearable pulse monitoring system, which can realize the synchronous measurements of pulse wave, skin temperature and pulse wave velocity (PWV). METHODS: A flexible sensor based on thermosensation is used to detect pressure and temperature stimuli simultaneously. Two sensors are integrated to detect pulse transit along two specific points of artery, e.g. Cun and Chi at a wrist, the data of which are subsequently used to figure out the PWV by using a tailor-designed algorithm conducted in a microprocessor. Calibration experiments and application cases are conducted to validate the effectiveness of the monitor. RESULTS: The developed monitor detects the physiological signals of pulse wave, PWV and skin temperature simultaneously. In addition, the monitor can measure the pulse changes before and after exercises, and tract skin temperature variations when warming and cooling. Moreover, the monitor can be also used to detect the local PWV at wrist. CONCLUSION: The synchronous measurements of pulse wave, skin temperature and PWV using a wearable monitor are feasible. SIGNIFICANCE: The monitor is small, simple-structured, with multifunction, and thus provides a promising auxiliary approach for traditional Chinese medicine (TCM) pulse diagnosis. PMID- 30295609 TI - A Fully Automated 3D In-vivo Delineation and Shape Parameterization of the Human Lamina Cribrosa in Optical Coherence Tomography. AB - OBJECTIVE: A fully automated method for delineation of the lamina cribrosa in optical coherence tomography (OCT) is proposed. It assesses the 3D shape of the lamina cribrosa in-vivo, based on a series of OCT B-scans. METHODS: The algorithm has several image processing steps and it is based on active contour detection performed along three orthogonal directions of the B-scan data cuboid. Further, the delineated 3D lamina cribrosa shape is parameterized with a fourth-order polynomial of two variables, P[x, y] using the least-squares method. Data sets from a total of 255 subjects from three groups were analyzed: 92 primary open angle glaucoma patients, 77 glaucoma suspects, and 86 controls. RESULTS: Statistically significant differences () were found in the coefficients of monomials , with both i and j even, between patients and controls and between suspects and controls. CONCLUSIONS: From the data obtained, it can be concluded that the mean shape parameterization of the lamina cribrosa of glaucoma suspects has similar appearance to that of glaucoma patients but it is markedly different from that of healthy controls. SIGNIFICANCE: The proposed algorithm enables automatically estimating, for the first time, the lamina cribrosa in 3D, further providing clinicians with a time efficient discrimination tool supporting glaucoma diagnosis. PMID- 30295610 TI - Source-Informed Segmentation: A Data-Driven Approach for the Temporal Segmentation of EEG. AB - GOAL: Understanding the dynamics of brain function through non-invasive neuroimaging techniques requires the development of computational techniques that can deal with the non-stationary properties of recorded activities. As a solution to this problem, a new data-driven segmentation method for recordings obtained through electroencephalography (EEG) is presented. METHODS: The proposed method utilizes singular value decomposition (SVD) to identify the time intervals in the EEG recordings during which, the spatial distribution of clusters of active cortical neurons remains quasi-stationary. Theoretical analysis shows that the spatial locality features of these clusters can be, asymptotically, captured by the most significant left singular subspace of the EEG data. A reference/sliding window approach is employed to dynamically extract this feature subspace, and the running error is monitored for significant changes using Kolmogorov-Smirnov (K-S) test. RESULTS: Simulation results, for a wide range of possible scenarios regarding the spatial distribution of active cortical neurons, show that the algorithm is successful in accurately detecting the segmental structure of the simulated EEG data. The algorithm is also applied to experimental EEG recordings of a modified visual oddball task. Results identify a unique sequence of dynamic patterns in the event-related potential (ERP) response for each of the three involved stimuli. CONCLUSION: The proposed method, without using source localization methods or scalp topographical maps, is able to identify intervals of quasi-stationary in the EEG recordings. SIGNIFICANCE: The proposed segmentation technique can offer new insights on the dynamics of functional organization of the brain in action. PMID- 30295606 TI - Motor thalamus supports striatum-driven reinforcement. AB - Reinforcement has long been thought to require striatal synaptic plasticity. Indeed, direct striatal manipulations such as self-stimulation of direct-pathway projection neurons (dMSNs) are sufficient to induce reinforcement within minutes. However, it's unclear what role, if any, is played by downstream circuitry. Here, we used dMSN self-stimulation in mice as a model for striatum-driven reinforcement and mapped the underlying circuitry across multiple basal ganglia nuclei and output targets. We found that mimicking the effects of dMSN activation on downstream circuitry, through optogenetic suppression of basal ganglia output nucleus substantia nigra reticulata (SNr) or activation of SNr targets in the brainstem or thalamus, was also sufficient to drive rapid reinforcement. Remarkably, silencing motor thalamus-but not other selected targets of SNr-was the only manipulation that reduced dMSN-driven reinforcement. Together, these results point to an unexpected role for basal ganglia output to motor thalamus in striatum-driven reinforcement. PMID- 30295607 TI - Dopamine neuron glutamate cotransmission evokes a delayed excitation in lateral dorsal striatal cholinergic interneurons. AB - : Dopamine neurons have different synaptic actions in the ventral and dorsal striatum (dStr), but whether this heterogeneity extends to dStr subregions has not been addressed. We have found that optogenetic activation of dStr dopamine neuron terminals in mouse brain slices pauses the firing of cholinergic interneurons in both the medial and lateral subregions, while in the lateral subregion the pause is shorter due to a subsequent excitation. This excitation is mediated mainly by metabotropic glutamate receptor 1 (mGluR1) and partially by dopamine D1-like receptors coupled to transient receptor potential channel 3 and 7. DA neurons do not signal to spiny projection neurons in the medial dStr, while they elicit ionotropic glutamate responses in the lateral dStr. The DA neurons mediating these excitatory signals are in the substantia nigra (SN). Thus, SN dopamine neurons engage different receptors in different postsynaptic neurons in different dStr subregions to convey strikingly different signals. Editorial note: This article has been through an editorial process in which the authors decide how to respond to the issues raised during peer review. The Reviewing Editor's assessment is that all the issues have been addressed (see decision letter). PMID- 30295611 TI - Rank Minimization for Snapshot Compressive Imaging. AB - Snapshot compressive imaging (SCI) refers to compressive imaging systems where multiple frames are mapped into a single measurement, with video compressive imaging and hyperspectral compressive imaging as two representative applications. Though exciting results of high-speed videos and hyperspectral images have been demonstrated, the poor reconstruction quality precludes SCI from wide applications.This paper aims to boost the reconstruction quality of SCI via exploiting the high-dimensional structure in the desired signal. We build a joint model to integrate the nonlocal self-similarity of video/hyperspectral frames and the rank minimization approach with the SCI sensing process. Following this, an alternating minimization algorithm is developed to solve this non-convex problem. We further investigate the special structure of the sampling process in SCI to tackle the computational workload and memory issues in SCI reconstruction. Both simulation and real data (captured by four different SCI cameras) results demonstrate that our proposed algorithm leads to significant improvements compared with current state-of-the-art algorithms. We hope our results will encourage the researchers and engineers to pursue further in compressive imaging for real applications. PMID- 30295612 TI - Denoising Prior Driven Deep Neural Network for Image Restoration. AB - Deep neural networks (DNNs) have shown very promising results for various image restoration (IR) tasks. However, the design of network architectures remains a major challenging for achieving further improvements. While most existing DNN based methods solve the IR problems by directly mapping low quality images to desirable high-quality images, the observation models characterizing the image degradation processes have been largely ignored. In this paper, we first propose a denoising-based IR algorithm, whose iterative steps can be computed efficiently. Then, the iterative process is unfolded into a deep neural network, which is composed of multiple denoisers modules interleaved with back-projection (BP) modules that ensure the observation consistencies. A convolutional neural network (CNN) based denoiser that can exploit the multi-scale redundancies of natural images is proposed. As such, the proposed network not only exploits the powerful denoising ability of DNNs, but also leverages the prior of the observation model. Through end-to-end training, both the denoisers and the BP modules can be jointly optimized. Experimental results on several IR tasks, e.g., image denoisig, super-resolution and deblurring show that the proposed method can lead to very competitive and often state-of-the-art results on several IR tasks, including image denoising, deblurring and super-resolution. PMID- 30295613 TI - Visual Permutation Learning. AB - We present a principled approach to uncover the structure of visual data by solving a deep learning task coined visual permutation learning. The goal of this task is to find the permutation that recovers the structure of data from shuffled versions of it. In the case of natural images, this task boils down to recovering the original image from patches shuffled by an unknown permutation matrix. Permutation matrices are discrete, thereby posing difficulties for gradient-based optimization methods. To this end, we resort to a continuous approximation using doubly-stochastic matrices and formulate a novel bi-level optimization problem on such matrices that learns to recover the permutation. Unfortunately, such a scheme leads to expensive gradient computations. We circumvent this issue by further proposing a computationally cheap scheme for generating doubly stochastic matrices based on Sinkhorn iterations. To implement our approach we propose DeepPermNet, an end-to-end CNN model for this task. The utility of DeepPermNet is demonstrated on three challenging computer vision problems, namely, relative attributes learning, supervised learning-to-rank, and self-supervised representation learning. Our results show state-of-the-art performance on relative attributes learning, supervised learning-to-rank, and competitive results in the classification and segmentation tasks of the PASCAL VOC dataset for self-supervised learning. PMID- 30295614 TI - Hyperspectral recovery from RGB images using Gaussian Processes. AB - We propose to recover spectral details from RGB images of known spectral quantization by modeling natural spectra under Gaussian Processes and combining them with the RGB images. Our technique exploits Process Kernels to model the relative smoothness of reflectance spectra, and encourages non-negativity in the resulting signals for better estimation of the reflectance values. The Gaussian Processes are inferred in sets using clusters of spatio-spectrally correlated hyperspectral training patches. Each set is transformed to match the spectral quantization of the test RGB image. We extract overlapping patches from the RGB image and match them to the hyperspectral training patches by spectrally transforming the latter. The RGB patches are encoded over the transformed Gaussian Processes related to those hyperspectral patches and the resulting image is constructed by combining the codes with the original Processes. Our approach infers the desired Gaussian Processes under a fully Bayesian model inspired by Beta-Bernoulli Process, for which we also present the inference procedure. A thorough evaluation using three hyperspectral datasets demonstrates the effective extraction of spectral details from RGB images by the proposed technique. PMID- 30295615 TI - First-Person Activity Forecasting from Video with Online Inverse Reinforcement Learning. AB - We address the problem of incrementally modeling and forecasting long-term goals of a first-person camera wearer: what the user will do, where they will go, and what goal they seek. In contrast to prior work in trajectory forecasting, our algorithm, DARKO, goes further to reason about semantic states (will I pick up an object?), and future goal states that are far in terms of both space and time. DARKO learns and forecasts from first-person visual observations of the user's daily behaviors via an Online Inverse Reinforcement Learning (IRL) approach. Classical IRL discovers only the rewards in a batch setting, whereas DARKO discovers the transitions, rewards, and goals of a user from streaming data. Among other results, we show DARKO forecasts goals better than competing methods in both noisy and ideal settings, and our approach is theoretically and empirically no-regret. PMID- 30295616 TI - Transient Convolutional Imaging. AB - While traditional imaging systems directly measure scene properties, computational imaging systems add computation to the measurement process, allowing such systems to extract non-trivially encoded scene features. This work demonstrates that exploiting structure in this process allows to recover information that is conventionally considered to be "lost". Relying on temporally and spatially convolutional structure, we extract a novel image modality that was essentially "invisible" before: a new temporal dimension of light propagation, obtained with consumer depth cameras. Using conventional Time-of-Flight cameras, a few seconds of capture and computation allows us to recover information that before could only be acquired in hours of capture time with specialized instrumentation at orders of magnitude higher cost. The novel type of image we capture allows us to make first steps toward the full inversion of light transport. Specifically, we demonstrate that Non-Line-of-Sight imaging and imaging in scattering media can be made feasible with the temporally resolved light transport acquired using Time-of-Flight depth cameras. PMID- 30295617 TI - A Flexible and Modular Receiver Coil Array for Magnetic Resonance Imaging. AB - We propose a flexible form-fitting MRI receiver coil array assembled by individual coil modules. This design targets MRI applications requiring a receiver array conforming to the anatomy of various shapes or sizes. Coil modules in our proposed array were arranged with gaps between them. Each coil module had a circumferential shielding structure stacked on top of the coil. Together they achieve robust decoupling when the array was bent differently. Two types of the circumferential shielding structure were investigated by using full-wave electromagnetic simulations and imaging experiments. Results showed that our flexible coil array had good decoupling between coils whether they were on a flat or curved surface with the S21 magnitude ranged between -18.1 dB and -19.9 dB in simulations, and with the average of off-diagonal entries of the noise correlation matrix less than 0.047 in experimental measurements. Anatomical images of human brain, calf, and knee were acquired by our seven-channel prototype on a 3T MRI system. The maximal and the average SNR within 50 mm from our array surpassed those from the commercial 32-channel head and 4-channel flexible coil arrays by 2.63/1.35-fold and 3.89/1.50-fold, respectively. PMID- 30295618 TI - Optimal Experiment Design for Magnetic Resonance Fingerprinting: Cramer-Rao Bound Meets Spin Dynamics. AB - Magnetic resonance (MR) fingerprinting is a new quantitative imaging paradigm, which simultaneously acquires multiple MR tissue parameter maps in a single experiment. In this paper, we present an estimation-theoretic framework to perform experiment design for MR fingerprinting. Specifically, we describe a discrete-time dynamic system to model spin dynamics, and derive an estimation theoretic bound, i.e., the Cramer-Rao bound (CRB), to characterize the signal-to noise ratio (SNR) efficiency of an MR fingerprinting experiment. We then formulate an optimal experiment design problem, which determines a sequence of acquisition parameters to encode MR tissue parameters with the maximal SNR efficiency, while respecting the physical constraints and other constraints from the image decoding/reconstruction process. We evaluate the performance of the proposed approach with numerical simulations, phantom experiments, and in vivo experiments. We demonstrate that the optimized experiments substantially reduce data acquisition time and/or improve parameter estimation. For example, the optimized experiments achieve about a factor of two improvement in the accuracy of T2 maps, while keeping similar or slightly better accuracy of T1 maps. Finally, as a remarkable observation, we find that the sequence of optimized acquisition parameters appears to be highly structured rather than randomly/pseudo-randomly varying as is prescribed in the conventional MR fingerprinting experiments. PMID- 30295619 TI - SUSHI: Sparsity-based Ultrasound Super-resolution Hemodynamic Imaging. AB - Identifying and visualizing vasculature within organs and tumors has major implications in managing cardiovascular diseases and cancer. Contrast-enhanced ultrasound scans detect slow-flowing blood, facilitating non-invasive perfusion measurements. However, their limited spatial resolution prevents the depiction of microvascular structures. Recently, super-localization ultrasonography techniques have surpassed this limit. However, they require long acquisition times of several minutes, preventing the detection of hemodynamic changes. We present a fast super-resolution method that exploits sparsity in the underlying vasculature and statistical independence within the measured signals. Similar to super localization techniques, this approach improves the spatial resolution by up to an order of magnitude compared to standard scans. Unlike super-localization methods, it requires acquisition times of only tens of milliseconds. We demonstrate a temporal resolution of ~25Hz, which may enable functional super resolution imaging deep within the tissue, surpassing the temporal resolution limitations of current super-resolution methods, e.g. in neural imaging. The sub second acquisitions make our approach robust to motion artifacts, simplifying in vivo use of super-resolution ultrasound. PMID- 30295620 TI - Edit Distance between Merge Trees. AB - Topological structures such as the merge tree provide an abstract and succinct representation of scalar fields. They facilitate effective visualization and interactive exploration of feature-rich data. A merge tree captures the topology of sub-level and super-level sets in a scalar field. Estimating the similarity between merge trees is an important problem with applications to feature-directed visualization of time-varying data. We present an approach based on tree edit distance to compare merge trees. The comparison measure satisfies metric properties, it can be computed efficiently, and the cost model for the edit operations is both intuitive and captures well-known properties of merge trees. Experimental results on time-varying scalar fields, 3D cryo electron microscopy data, shape data, and various synthetic datasets show the utility of the edit distance towards a feature-driven analysis of scalar fields. PMID- 30295621 TI - Dictionary-based Fidelity Measure for Virtual Traffic. AB - Aiming at objectively measuring the realism of virtual traffic flows and evaluating the effectiveness of different traffic simulation techniques, this paper introduces a general, dictionary-based learning method to evaluate the fidelity of any traffic trajectory data. First, a traffic pattern dictionary that characterizes common patterns of real-world traffic behavior is built offline from pre-collected ground truth traffic data. The corresponding learning error is set as the benchmark of the dictionary-based traffic representation. With the aid of the constructed dictionary, the realism of input simulated traffic flow data can be evaluated by comparing its dictionary-based reconstruction error with the dictionary error benchmark. This evaluation metric can be robustly applied to any simulated traffic flow data; in other words, it is independent of how the traffic data are generated. We demonstrated the effectiveness and robustness of this metric through many experiments on real-world traffic data and various simulated traffic data, comparisons with the state-of-the-art entropy-based similarity metric for aggregate crowd motions, and perceptual evaluation studies. PMID- 30295622 TI - 3D Objects Clouds: Viewing Virtual Objects in Interactive Clouds. AB - Given the expanding use of 3D Objects in a variety of fields such as animation, gaming, virtual worlds, commerce, augmented reality and 3D printing, we present a novel system for object browsing and searching. Specifically, the system packs objects into an interactive 3D cloud for browsing and searching on mobile devices. It was designed with the aim of increasing search efficiency in a variety of active environments, while providing a visually engaging layout, and we evaluated this by conducting a comparative user study. We show that our system can significantly decrease search times compared to the classic grid-based layout that is used extensively, and it has been suggested by subjects that cloud-based searching is more interesting and visually-engaging. PMID- 30295623 TI - Towards BCI-based Interfaces for Augmented Reality: Feasibility, Design and Evaluation. AB - Brain-Computer Interfaces (BCIs) enable users to interact with computers without any dedicated movement, bringing new hands-free interaction paradigms. In this paper we study the combination of BCI and Augmented Reality (AR). We first tested the feasibility of using BCI in AR settings based on Optical See-Through Head Mounted Displays (OST-HMDs). Experimental results showed that a BCI and an OST HMD equipment (EEG headset and Hololens in our case) are well compatible and that small movements of the head can be tolerated when using the BCI. Second, we introduced a design space for command display strategies based on BCI in AR, when exploiting a famous brain pattern called Steady-State Visually Evoked Potential (SSVEP). Our design space relies on five dimensions concerning the visual layout of the BCI menu; namely: orientation, frame-of-reference, anchorage, size and explicitness. We implemented various BCI-based display strategies and tested them within the context of mobile robot control in AR. Our findings were finally integrated within an operational prototype based on a real mobile robot that is controlled in AR using a BCI and a HoloLens headset. Taken together our results (4 user studies, 94 participants) and our methodology could pave the way to future interaction schemes in AR exploiting 3D User Interfaces based on brain activity and BCIs. PMID- 30295624 TI - Door and Doorway Etiquette for Virtual Humans. AB - We introduce a framework for simulating a variety of nontrivial, socially motivated behaviors that underlie the orderly passage of pedestrians through doorways, especially the common courtesy of opening and holding doors open for others, an important etiquette that has been overlooked in the literature on autonomous multi-human animation. Emulating such social activity requires serious attention to the interplay of visual perception, navigation in constrained doorway environments, manipulation of a variety of door types, and high-level decision making based on social considerations. To tackle this complex human simulation problem, we take an artificial life approach to modeling autonomous pedestrians, proposing a layered architecture comprising mental, behavioral, and motor layers. The behavioral layer couples two stages: (1) a decentralized, agent based strategy for dynamically determining the well-mannered ordering of pedestrians around doorways, and (2) a state-based model that directs and coordinates a pedestrian's interactions with the door. The mental layer is a Bayesian network decision model that dynamically selects appropriate door holding behaviors by considering both internal and external social factors pertinent to pedestrians interacting with one another in and around doorways. Our framework addresses the various door types in common use and supports a variety of doorway etiquette scenarios with efficient, real-time performance. PMID- 30295625 TI - Gestural Interaction and Visual Illusion for Lower Limbs' Neuropathic Pain Treatment. AB - Pain caused by a lesion or a disease affecting the somatosensory nervous system is known as Neuropathic pain. It has been shown that neuropathic pain can be treated with the combination of simultaneous transcranial direct current stimulation and the generation of the visual illusion that the patient retains control of the affected limbs. For persons with neuropathic pain in the lower limbs, the visual illusion consists of an image of the patient walking normally. Such a visual illusion has classically been generated by using a physical mirror and a projector. The objective of this paper is to develop and validate a computer-based version of the visual illusion, including Gestural Control. The developed system has been validated in a trial and has been successfully implanted in daily clinical practice in a reference neurorehabilitation hospital. A retrospective statistical analysis shows that the patients treated with the computer-based system reduce their pain level significantly more than the patients treated with the mirror and projector treatment before the introduction of the computer-based version. Furthermore, it also makes possible to bring the therapy to the home of the patients, where the treatment can be self-administered while still being monitored by the clinical staff. PMID- 30295626 TI - Plant Species Identification from Occluded Leaf Images. AB - We present an approach to identify the plant species from the contour information from occluded leaf image using a database of full plant leaves. Although contour based 2D shape matching has been studied extensively in the last couple of decades, matching occluded leaves with full leaf databases is an open and little worked on problem. Classifying occluded plant leaves is even more challenging than full leaf matching because of large variations and complexity of leaf structures. Matching an occluded contour with all the full contours in a database is an NP-hard problem, so our algorithm is necessarily suboptimal. First, we represent the 2D contour points as a beta-Spline curve. Then we extract interest points on these curves via the Discrete Contour Evolution (DCE) algorithm. We use subgraph matching using the DCE points as graph nodes, which produces a number of open curves for each closed leaf contour. Next, we compute the similarity transformation parameters (translation, rotation and uniform scaling) for each open curve. We then "overlay" each open curve with the inverse similarity transformed occluded curve and use the Frechet distance metric to measure the quality of the match, retaining the best eta matched curves. Since the Frechet metric is cheap to compute but not perfectly correlated with the quality of the match, we formulate an energy functional that is well correlated with the quality of the match, but is considerably more expensive to compute. The functional uses local and global curvature, Shape Context descriptors and String Cut features. We minimize this energy functional using a convex-concave relaxation framework. The curve among these best eta curves, that has the minimum energy, is considered to be the best overall match with the occluded leaf. Experiments on three publicly available leaf image database shows that our method is both effective and efficient, outperforming other current state-of-the-art methods. Occlusion is measured as the percentage of the overall contour (and not leaf area) that is missing. We show our algorithm can, even for leaves with a high amounts of occlusion (say 50% occlusion), still identify the best full leaf match from the databases. PMID- 30295627 TI - Secondary Structure and Contact Guided Differential Evolution for Protein Structure Prediction. AB - Ab initio protein tertiary structure prediction is one of the long-standing problems in structural bioinformatics. With the help of the residue-residue contact and secondary structure prediction information, the accuracy of ab initio structure prediction can be enhanced. In this study, an improved differential evolution using the secondary structure and residue-residue contact information referred to as SCDE is proposed for protein structure prediction. In SCDE, two score models based on the secondary structure and contact information are proposed, and two selection strategies, namely, secondary structure-based selection strategy and contact-based selection strategy, are designed to guide conformation space search. In addition, a probability distribution function is designed to balance these two selection strategies. Experimental results on a benchmark dataset with 28 proteins and 4 free model targets in CASP12 demonstrate that the proposed SCDE is effective and efficient. PMID- 30295628 TI - Maximizing Data Transmission Rate for Implantable Devices Over a Single Inductive Link: Methodological Review. AB - Due to the constantly growing geriatric population and the projected increase of the prevalence of chronic diseases that are refractory to drugs, Implantable Medical Devices (IMDs) such as neurostimulators, endoscopic capsules, artificial retinal prostheses, and brain-machine interfaces are being developed. According to many business forecast firms, the IMD market is expected to grow and they are subject to much research aiming to overcome the numerous challenges of their development. One of these challenges consists of designing a wireless power and data transmission system that has high power efficiency, highdata rates, low power consumption, and high-robustness against noise. This is in addition to minimal design and implementation complexity. This manuscript concerns a comprehensive survey of the latest techniques used to power up and communicate between an external base station and an IMD. Patient safety considerations related to biological, physical, electromagnetic and electromagnetic interference concerns for wireless IMDs are also explored. The simultaneous powering and data communication techniques using a single inductive link for both power transfer and bidirectional data communication; including the various data modulation/demodulation techniques; are also reviewed. This review will hopefully contribute to the persistent efforts to implement compact reliable IMDs while lowering their cost and up-surging their benefits. PMID- 30295629 TI - Novel Finite-Time Synchronization Criteria for Inertial Neural Networks With Time Delays via Integral Inequality Method. AB - In this paper, we are concerned with the finite-time synchronization of a class of inertial neural networks with time delays. Without applying some finite-time stability theorems, which are widely applied to studying the finite-time synchronization for neural networks, by constructing two Lyapunov functions and using integral inequality method, two sufficient conditions on the finite-time synchronization for a class of inertial neural networks with time delays are derived. Considering that the method and research results of the finite-time synchronization are different from some existing works, this paper extends the works on the finite-time synchronization of neural networks. PMID- 30295630 TI - Hypergraph-Induced Convolutional Networks for Visual Classification. AB - At present, convolutional neural networks (CNNs) have become popular in visual classification tasks because of their superior performance. However, CNN-based methods do not consider the correlation of visual data to be classified. Recently, graph convolutional networks (GCNs) have mitigated this problem by modeling the pairwise relationship in visual data. Real-world tasks of visual classification typically must address numerous complex relationships in the data, which are not fit for the modeling of the graph structure using GCNs. Therefore, it is vital to explore the underlying correlation of visual data. Regarding this issue, we propose a framework called the hypergraph-induced convolutional network to explore the high-order correlation in visual data during deep neural networks. First, a hypergraph structure is constructed to formulate the relationship in visual data. Then, the high-order correlation is optimized by a learning process based on the constructed hypergraph. The classification tasks are performed by considering the high-order correlation in the data. Thus, the convolution of the hypergraph-induced convolutional network is based on the corresponding high-order relationship, and the optimization on the network uses each data and considers the high-order correlation of the data. To evaluate the proposed hypergraph induced convolutional network framework, we have conducted experiments on three visual data sets: the National Taiwan University 3-D model data set, Princeton Shape Benchmark, and multiview RGB-depth object data set. The experimental results and comparison in all data sets demonstrate the effectiveness of our proposed hypergraph-induced convolutional network compared with the state-of-the art methods. PMID- 30295631 TI - Early Expression Detection via Online Multi-Instance Learning With Nonlinear Extension. AB - Video-based facial expression recognition has received substantial attention over the past decade, while early expression detection (EED) is still a relatively new and challenging problem. The goal of EED is to identify an expression as quickly as possible after the expression starts and before it ends. This timely ability has many potential applications, ranging from human-computer interaction to security. The max-margin early event detector (MMED) is a well-known ranking model for early event detection. It can achieve competitive EED performance but suffers from several critical limitations: 1) MMED lacks flexibility in extracting useful information for segment comparison, which leads to poor performance in exploring the ranking relation between segment pairs; 2) the training process is slow due to the large number of constraints, and the memory requirement is also usually hard to satisfy; and 3) MMED is linear in nature, and hence may not be appropriate for data in a nonlinear feature space. To overcome these limitations, we propose an online multi-instance learning (MIL) framework for EED. In particular, the MIL technique is first introduced to generalize MMED, resulting in the proposed MIL-based EED (MIED), which is more general and flexible than MMED, since various instance construction and combination strategies can be adopted. To accelerate the training process, we reformulate MIED in the online setting and develop online multi-instance learning framework for EED (OMIED). To further exploit the nonlinear structure of the data distribution, we incorporate the kernel methods in OMIED, which results in the proposed online kernel multi-instance learning for early expression detection. Experiments on two popular and one challenging video-based expression data sets demonstrate both the efficiency and effectiveness of the proposed methods. PMID- 30295632 TI - LTNN: A Layerwise Tensorized Compression of Multilayer Neural Network. AB - An efficient deep learning requires a memory-efficient construction of a neural network. This paper introduces a layerwise tensorized formulation of a multilayer neural network, called LTNN, such that the weight matrix can be significantly compressed during training. By reshaping the multilayer neural network weight matrix into a high-dimensional tensor with a low-rank approximation, significant network compression can be achieved with maintained accuracy. An according layerwise training is developed by a modified alternating least-squares method with backward propagation for fine-tuning only. LTNN can provide the state-of-the art results on various benchmarks with significant compression. For MNIST benchmark, LTNN shows $64 x$ compression rate without accuracy drop. For Imagenet12 benchmark, our proposed LTNN achieves $35.84 x$ compression of the neural network with around 2% accuracy drop. We have also shown $1.615 x$ faster on inference speed than the existing works due to the smaller tensor core ranks.

AB - The current study explored the feasibility of automated characterization of functional mobility via an Instrumented Cane System (ICS) within an older adult sample of cane users. An off-the-shelf offset cane was instrumented with inertial, force, and ultrasound sensors for non-invasive data collection. Eighteen patients from a neurological out-patient rehabilitation clinic and nine independently-mobile controls participated in standard clinical evaluations of mobility using the ICS while under the care of an attending physical therapist. Feasibility of the ICS was gauged through two studies. The first demonstrated the capability of the ICS to reliably collect meaningful usage metrics, and the second provided preliminary support for the discriminability of high and low falls risk from system-reported metrics. Specifically, the cane significantly differentiated patients and controls (), and a measure of the variation in rotational velocity was associated with total scores on the Functional Gait Assessment (). These findings may ultimately serve to complement and even extend current clinical assessment practices.

AB - Manual segmentation of the brain tumors for cancer diagnosis from MRI images is a difficult, tedious and time-consuming task. The accuracy and the robustness of brain tumor segmentation, therefore, are crucial for the diagnosis, treatment planning, and treatment outcome evaluation. Mostly, the automatic brain tumor segmentation methods use hand designed features. Similarly, traditional methods of Deep learning such as Convolutional Neural Networks require a large amount of annotated data to learn from, which is often difficult to obtain in the medical domain. Here we describe a new model Two-Pathway-Group CNN architecture for brain tumor segmentation, which exploits local features and global contextual features simultaneously. This model enforces equivariance in the Two-Pathway CNN model to reduce instabilities and overfitting parameter sharing. Finally, we embed the cascade architecture into Two-Pathway-Group CNN in which the output of a basic CNN is treated as an additional source and concatenated at the last layer. Validation of the model on BRATS2013 and BRATS2015 datasets revealed that embedding of a group CNN into a two pathway architecture improved the overall performance over the currently published state-of-the-art while computational complexity remains attractive. PMID- 30295635 TI - Microsimulation Model Using Christiana Care Early Warning System (CEWS) to Evaluate Physiological Deterioration. AB - While physiological warning signs prior to deterioration events during hospitalization have been widely studied, evaluating clinical interventions, such as Rapid Response Team (RRT) activations, based on scoring systems remains an understudied area. Simulation of physiological deterioration patterns represented by scoring systems can facilitate testing different RRT policies without disturbing care processes. Christiana Care Early Warning System (CEWS) is a scoring system developed at the study hospital to detect the physiological warning signs and inform RRT activations. The objective of this study is to evaluate CEWS-triggered RRT policies based on patient demographics and policy structures. Using retrospective data derived from a subset of Electronic Health Records between December 2015 and December 2016 (6,000 patients), we developed a microsimulation model with integrated regression analysis to compare RRT policies on subpopulations defined by age, gender and comorbidities to find score thresholds that result in lowest percent of time spent above critical CEWS values. Policies that rely on average scores were more sensitive to threshold changes compared to policies that rely on current value and change in CEWS. Policy using score threshold 10 provided the lowest percentage of time in critical condition for majority of subpopulations. The proposed model is a novel framework to simulate individual deterioration patterns and systematically evaluate RRT policies based on their impact on health conditions. Our work highlights the importance of integration of data-driven models into personalized care, and represents a significant opportunity to inform biomedical and health informatics research on designing and evaluating EWS-based clinical interventions. PMID- 30295636 TI - Bi-objective Elite Differential Evolution Algorithm for Multivalued Logic Networks. AB - In this paper, a novel algorithm called bi-objective elite differential evolution (BOEDE) is proposed to optimize multivalued logic (MVL) networks. It is a multiobjective algorithm completely different from all previous single-objective optimization ones. The two objective functions, error and optimality, are put into evaluating the fitness of individuals in evolution simultaneously. BOEDE innovatively uses an archive population with different ranks to store elite individuals and offsprings. Moreover, a characteristic updating method based on this archive structure is designed to produce the parent population. Because of the particularity of MVL network problems, the performance of BOEDE to solve them is further improved by strictly distinguishing elite solutions and Pareto optimal solutions, and by modifying the method of dealing with illegal variables. The simulations show that BOEDE can collect a great number of solutions to provide decision support for a variety of applications. The comparison results also indicate that BOEDE is significantly better than the existing algorithms. PMID- 30295637 TI - Spectral Clustering by Joint Spectral Embedding and Spectral Rotation. AB - Spectral clustering is an important clustering method widely used for pattern recognition and image segmentation. Classical spectral clustering algorithms consist of two separate stages: 1) solving a relaxed continuous optimization problem to obtain a real matrix followed by 2) applying K-means or spectral rotation to round the real matrix (i.e., continuous clustering result) into a binary matrix called the cluster indicator matrix. Such a separate scheme is not guaranteed to achieve jointly optimal result because of the loss of useful information. To obtain a better clustering result, in this paper, we propose a joint model to simultaneously compute the optimal real matrix and binary matrix. The existing joint model adopts an orthonormal real matrix to approximate the orthogonal but nonorthonormal cluster indicator matrix. It is noted that only in a very special case (i.e., all clusters have the same number of samples), the cluster indicator matrix is an orthonormal matrix multiplied by a real number. The error of approximating a nonorthonormal matrix is inevitably large. To overcome the drawback, we propose replacing the nonorthonormal cluster indicator matrix with a scaled cluster indicator matrix which is an orthonormal matrix. Our method is capable of obtaining better performance because it is easy to minimize the difference between two orthonormal matrices. Experimental results on benchmark datasets demonstrate the effectiveness of the proposed method (called JSESR). PMID- 30295638 TI - Generative and Discriminative Fuzzy Restricted Boltzmann Machine Learning for Text and Image Classification. AB - The restricted Boltzmann machine (RBM) is an excellent generative learning model for feature extraction. By extending its parameters from real numbers to fuzzy ones, we have developed the fuzzy RBM (FRBM) which is demonstrated to possess better generative capability than RBM. In this paper, we first propose a generative model named Gaussian FRBM (GFRBM) to deal with real-valued inputs. Then, motivated by the fact that the discriminative variant of RBM can provide a self-contained framework for classification with competitive performance compared with some traditional classifiers, we establish the discriminative FRBM (DFRBM) and discriminative GFRBM (DGFRBM) that combine both the generative and discriminative facility by adding extra neurons next to the input units. Specifically, they can be trained into excellent stand-alone classifiers and retain outstanding generative capability simultaneously. The experimental results including text and image (both clean and noisy) classification indicate that DFRBM and DGFRBM outperform discriminative RBM models in terms of reconstruction and classification accuracy, and they behave more stable when encountering noisy data. Moreover, the proposed learning models show some promising advantages over other standard classifiers. PMID- 30295639 TI - Finite-Time Synchronization and Hinfinity Synchronization of Multiweighted Complex Networks With Adaptive State Couplings. AB - In this paper, two kinds of multiweighted and adaptive state coupled complex networks (CNs) with or without coupling delays are presented. First, we develop the appropriate state feedback controller and adaptive law for the sake of guaranteeing that the proposed network models without coupling delays can be finite-timely synchronized and Hinfinity synchronized. Furthermore, for the multiweighted CNs with coupling delays and adaptive state couplings, some finite time synchronization and Hinfinity synchronization criteria are presented by choosing the appropriate adaptive law and controllers. Eventually, we give two numerical simulations to verify the validity of the theoretical results. PMID- 30295640 TI - Probabilistic Rank-One Discriminant Analysis via Collective and Individual Variation Modeling. AB - Linear discriminant analysis (LDA) is a classical supervised subspace learning technique that has wide applications. However, it is designed for vector only, which cannot exploit the tensor structures and may lead to suboptimal results when dealing with tensorial data. To address this problem, several multilinear LDA (MLDA) methods have been proposed to learn the subspaces from tensors. By exploiting the tensor structures, they achieve compact subspace representations, reduced parameter sizes, and improved robustness against the small sample size problem. However, existing MLDA methods do not take data uncertainty into account, fail to converge properly, or have to introduce additional tuning parameters for good convergence properties. In this paper, we therefore solve these limitations by proposing a probabilistic MLDA method for matrix inputs. Specifically, we propose a new generative model to incorporate structural information into the probabilistic framework, where each observed matrix is represented as a linear combination of collective and individual rank-one matrices. This provides our method with both the expressiveness of capturing discriminative features and nondiscriminative noise, and the capability of exploiting the 2-D tensor structures. To overcome the convergence problem of existing MLDAs, we develop an EM-type algorithm for parameter estimation, which has closed-form solutions with convergence guarantees. Experimental results on real-world datasets show the superiority of the proposed method to other probabilistic and MLDA variants. PMID- 30295641 TI - Emergent Inference of Hidden Markov Models in Spiking Neural Networks Through Winner-Take-All. AB - Hidden Markov models (HMMs) underpin the solution to many problems in computational neuroscience. However, it is still unclear how to implement inference of HMMs with a network of neurons in the brain. The existing methods suffer from the problem of being nonspiking and inaccurate. Here, we build a precise equivalence between the inference equation of HMMs with time-invariant hidden variables and the dynamics of spiking winner-take-all (WTA) neural networks. We show that the membrane potential of each spiking neuron in the WTA circuit encodes the logarithm of the posterior probability of the hidden variable in each state, and the firing rate of each neuron is proportional to the posterior probability of the HMMs. We prove that the time course of the neural firing rate can implement posterior inference of HMMs. Theoretical analysis and experimental results show that the proposed WTA circuit can get accurate inference results of HMMs. PMID- 30295642 TI - Escorting alpha-globin to eNOS: alpha-globin-stabilizing protein paves the way. AB - In the vascular wall, endothelial nitric oxide synthase (eNOS) produces NO to regulate peripheral vascular resistance, tissue perfusion, and blood pressure. In resistance arteries, eNOS couples with alpha-globin and, through chemical reactions, modulates NO diffusion needed for vascular smooth muscle relaxation. While alpha-globin protein alone is known to be unstable, the mechanisms that enable alpha-globin protein expression remain elusive. Here, Lechauve et al. report that arterial endothelium expresses alpha hemoglobin-stabilizing protein, which acts as a critical chaperone protein for alpha-globin expression and vascular function. PMID- 30295644 TI - The post-2009 influenza pandemic era: time to revisit antibody immunodominance. AB - The current inactivated influenza vaccines rely on the induction of neutralizing antibodies against the head domain of the viral hemagglutinin (HA). The HA head contains five immunodominant antigenic sites, all of which are subject to antigenic drift, thereby limiting vaccine efficacy. Bypassing the immune system's tendency to focus on the most variable regions of the HA may be a step toward more broadly protective influenza vaccines. However, this requires a better understanding of the biological meaning of immunodominance, and of the hierarchy between different antigenic sites. In this issue of the JCI, Liu et al. determined the immunodominance of the five antigenic sites of the HA head in experimentally infected mice, guinea pigs, and ferrets. All three species exhibited different preferences for the five sites of the 2009 pandemic H1N1 strain. Moreover, human subjects exhibited yet a different pattern of immunodominance following immunization with the standard inactivated influenza vaccine. Together, these results have important implications for influenza vaccine design and interpretation of animal models. PMID- 30295643 TI - Angiopoietin-2 exacerbates cardiac hypoxia and inflammation after myocardial infarction. AB - Emerging evidence indicates that angiopoietin-2 (Angpt2), a well-recognized vascular destabilizing factor, is a biomarker of poor outcome in ischemic heart disease. However, its precise role in postischemic cardiovascular remodeling is poorly understood. Here, we show that Angpt2 plays multifaceted roles in the exacerbation of cardiac hypoxia and inflammation after myocardial ischemia. Angpt2 was highly expressed in endothelial cells at the infarct border zone after myocardial infarction (MI) or ischemia/reperfusion injury in mice. In the acute phase of MI, endothelial-derived Angpt2 antagonized Angpt1/Tie2 signaling, which was greatly involved in pericyte detachment, vascular leakage, increased adhesion molecular expression, degradation of the glycocalyx and extracellular matrix, and enhanced neutrophil infiltration and hypoxia in the infarct border area. In the chronic remodeling phase after MI, endothelial- and macrophage-derived Angpt2 continuously promoted abnormal vascular remodeling and proinflammatory macrophage polarization through integrin alpha5beta1 signaling, worsening cardiac hypoxia and inflammation. Accordingly, inhibition of Angpt2 either by gene deletion or using an anti-Angpt2 blocking antibody substantially alleviated these pathological findings and ameliorated postischemic cardiovascular remodeling. Blockade of Angpt2 thus has potential as a therapeutic option for ischemic heart failure. PMID- 30295645 TI - Macrophage migration inhibitory factor mediates metabolic dysfunction induced by atypical antipsychotic therapy. AB - Atypical antipsychotics are highly effective antischizophrenic medications but their clinical utility is limited by adverse metabolic sequelae. We investigated whether upregulation of macrophage migration inhibitory factor (MIF) underlies the insulin resistance that develops during treatment with the most commonly prescribed atypical antipsychotic, olanzapine. Olanzapine monotherapy increased BMI and circulating insulin, triglyceride, and MIF concentrations in drug-naive schizophrenic patients with normal MIF expression, but not in genotypic low MIF expressers. Olanzapine administration to mice increased their food intake and hypothalamic MIF expression, which led to activation of the appetite-related AMP activated protein kinase and Agouti-related protein pathway. Olanzapine also upregulated MIF expression in adipose tissue, which reduced lipolysis and increased lipogenic pathways. Increased plasma lipid concentrations were associated with abnormal fat deposition in liver and skeletal muscle, which are important determinants of insulin resistance. Global MIF-gene deletion protected mice from olanzapine-induced insulin resistance, as did intracerebroventricular injection of neutralizing anti-MIF antibody, supporting the role of increased hypothalamic MIF expression in metabolic dysfunction. These findings uphold the potential pharmacogenomic value of MIF genotype determination and suggest that MIF may be a tractable target for reducing the metabolic side effects of atypical antipsychotic therapy. PMID- 30295648 TI - Assessment of Resistance to Tyrosine Kinase Inhibitors by an Interrogation of Signal Transduction Pathways by Antibody Arrays. AB - Cancer patients with an aberrant regulation of the protein phosphorylation networks are often treated with the tyrosine kinase inhibitors. Response rates approaching 85% are common. Unfortunately, patients often become refractory to the treatment by altering their signal transduction pathways. An implementation of the expression profiling with microarrays can identify the overall mRNA-level changes, and proteomics can identify the overall changes in protein levels or can identify the proteins involved, but the activity of the signal transduction pathways can only be established by interrogating post-translational modifications of the proteins. As a result, the ability to identify whether a drug treatment is successful or whether resistance arose, or the ability to characterize any alterations in the signaling pathways, is an important clinical challenge. Here, we provide a detailed explanation of antibody arrays as a tool which can identify system-wide alterations in various post-translational modifications (e.g., phosphorylation). One of the advantages of using antibody arrays includes their accessibility (an array does not require either an expert in proteomics or costly equipment) and speed. The availability of arrays targeting a combination of post-translational modifications is the primary limitation. In addition, unbiased approaches (phosphoproteomics) may be more suitable for the novel discovery, whereas antibody arrays are ideal for the most widely characterized targets. PMID- 30295646 TI - Endothelial cell alpha-globin and its molecular chaperone alpha-hemoglobin stabilizing protein regulate arteriolar contractility. AB - Arteriolar endothelial cell-expressed (EC-expressed) alpha-globin binds endothelial NOS (eNOS) and degrades its enzymatic product, NO, via dioxygenation, thereby lessening the vasodilatory effects of NO on nearby vascular smooth muscle. Although this reaction potentially affects vascular physiology, the mechanisms that regulate alpha-globin expression and dioxygenase activity in ECs are unknown. Without beta-globin, alpha-globin is unstable and cytotoxic, particularly in its oxidized form, which is generated by dioxygenation and recycled via endogenous reductases. We show that the molecular chaperone alpha hemoglobin-stabilizing protein (AHSP) promotes arteriolar alpha-globin expression in vivo and facilitates its reduction by eNOS. In Ahsp-/- mice, EC alpha-globin was decreased by 70%. Ahsp-/- and Hba1-/- mice exhibited similar evidence of increased vascular NO signaling, including arteriolar dilation, blunted alpha1 adrenergic vasoconstriction, and reduced blood pressure. Purified alpha-globin bound eNOS or AHSP, but not both together. In ECs in culture, eNOS or AHSP enhanced alpha-globin expression posttranscriptionally. However, only AHSP prevented oxidized alpha-globin precipitation in solution. Finally, eNOS reduced AHSP-bound alpha-globin approximately 6-fold faster than did the major erythrocyte hemoglobin reductases (cytochrome B5 reductase plus cytochrome B5). Our data support a model whereby redox-sensitive shuttling of EC alpha-globin between AHSP and eNOS regulates EC NO degradation and vascular tone. PMID- 30295649 TI - Dynamic Adhesion Assay for the Functional Analysis of Anti-adhesion Therapies in Inflammatory Bowel Disease. AB - Gut homing of immune cells is important for the pathogenesis of inflammatory bowel diseases (IBD). Integrin-dependent cell adhesion to addressins is a crucial step in this process and therapeutic strategies interfering with adhesion have been successfully established. The anti-alpha4beta7 integrin antibody, vedolizumab, is used for the clinical treatment of Crohn's disease (CD) and ulcerative colitis (UC) and further compounds are likely to follow. The details of the adhesion procedure and the action mechanisms of anti-integrin antibodies are still unclear in many regards due to the limited available techniques for the functional research in this field. Here, we present a dynamic adhesion assay for the functional analysis of human cell adhesion under flow conditions and the impact of anti-integrin therapies in the context of IBD. It is based on the perfusion of primary human cells through addressin-coated ultrathin glass capillaries with real-time microscopic analysis. The assay offers a variety of opportunities for refinements and modifications and holds potentials for mechanistic discoveries and translational applications. PMID- 30295650 TI - CRISPR/Cas9 Gene Editing to Make Conditional Mutants of Human Malaria Parasite P. falciparum. AB - Malaria is a significant cause of morbidity and mortality worldwide. This disease, which primarily affects those living in tropical and subtropical regions, is caused by infection with Plasmodium parasites. The development of more effective drugs to combat malaria can be accelerated by improving our understanding of the biology of this complex parasite. Genetic manipulation of these parasites is key to understanding their biology; however, historically the genome of P. falciparum has been difficult to manipulate. Recently, CRISPR/Cas9 genome editing has been utilized in malaria parasites, allowing for easier protein tagging, generation of conditional protein knockdowns, and deletion of genes. CRISPR/Cas9 genome editing has proven to be a powerful tool for advancing the field of malaria research. Here, we describe a CRISPR/Cas9 method for generating glmS-based conditional knockdown mutants in P. falciparum. This method is highly adaptable to other types of genetic manipulations, including protein tagging and gene knockouts. PMID- 30295647 TI - DeltaNp63-driven recruitment of myeloid-derived suppressor cells promotes metastasis in triple-negative breast cancer. AB - Triple-negative breast cancer (TNBC) is particularly aggressive, with enhanced incidence of tumor relapse, resistance to chemotherapy, and metastases. As the mechanistic basis for this aggressive phenotype is unclear, treatment options are limited. Here, we showed an increased population of myeloid-derived immunosuppressor cells (MDSCs) in TNBC patients compared with non-TNBC patients. We found that high levels of the transcription factor DeltaNp63 correlate with an increased number of MDSCs in basal TNBC patients, and that DeltaNp63 promotes tumor growth, progression, and metastasis in human and mouse TNBC cells. Furthermore, we showed that MDSC recruitment to the primary tumor and metastatic sites occurs via direct DeltaNp63-dependent activation of the chemokines CXCL2 and CCL22. CXCR2/CCR4 inhibitors reduced MDSC recruitment, angiogenesis, and metastasis, highlighting a novel treatment option for this subset of TNBC patients. Finally, we found that MDSCs secrete prometastatic factors such as MMP9 and chitinase 3-like 1 to promote TNBC cancer stem cell function, thereby identifying a nonimmunologic role for MDSCs in promoting TNBC progression. These findings identify a unique crosstalk between DeltaNp63+ TNBC cells and MDSCs that promotes tumor progression and metastasis, which could be exploited in future combined immunotherapy/chemotherapy strategies for TNBC patients. PMID- 30295651 TI - Anogenital Distance and Perineal Measurements of the Pelvic Organ Prolapse (POP) Quantification System. AB - Anogenital distance (AGD) is a sexually dimorphic attribute, twice longer in males than in females, and a marker of intrauterine hormonal environment. Interest in AGD measurements is increasing due to mounting evidence on their potential clinical implications. A parallel set of perineal measurements, the Pelvic Organ Prolapse Quantification System (POP-Q), include similar, but not exactly the same, landmarks: the perineal body (PB) and the genital hiatus (GH) lengths. However, clinical reproducibility of both perineal measurements and their usefulness to describe perineal anthropometry needs to be elucidated. To our knowledge, there is no publication in video format showing the methodology of these measurements. The main objective of this work is to show how to properly perform perineal anthropometry, including measurements of the AGD in its two variants [anoclitoral (AGDAC) and anofourchette (AGDAF)], genital hiatus (GH) and perineal body (PB). Moreover, we explored if there were differences in these measurements in women with and without Pelvic Organ Prolapse (POP). We research whether the anthropometric characteristics of the perineum, such as AGD (which is determined prenatally), may be altered in these women and be an independent etiological factor for pelvic floor dysfunction. We show two different ways of measuring perineal lengths, as they might be quite comparable. Our suggestion is that unifying perineal measurements could be useful for clinical and biomedical investigation. More studies are needed in order to compare GH and PB measurements and its AGD counterparts to analyze which procedures are more reproducible with less intra and interobserver variability. PMID- 30295652 TI - Olfactory Context Dependent Memory: Direct Presentation of Odorants. AB - Information is retrieved more effectively when the retrieval occurs in the same context as that in which the information was first encoded. This is termed context dependent memory (CDM). One category of cues that have been shown to effectively produce CDM effects are odors. However, it is unclear what the boundary conditions of these CDM effects are. In particular, given that olfaction has been called an implicit sense, it is possible that odors are only effective mnemonic cues when they are presented in the background. This assertion seems even more likely given that previous research has shown odors to be poor cues during paired associate memory tests, where odors are in the focus of attention as mnemonic cues for other information. In order to determine whether odors are only effective contextual mnemonic cues when presented outside the central focus of an observer, an olfactory CDM experiment was performed in which odorants were presented directly, rather than ambiently. Direct presentation was accomplished with the aid of an olfactometer. The olfactometer not only allows for direct presentation of odorants, but provides other methodological benefits, including the allowance of trial by trial manipulations of odorant presentations and, relatedly, time-specific releases of odorants. The presence of the same odor during both encoding and retrieval enhanced memory performance, regardless of whether the odor was presented ambiently or directly. This finding can serve as a basis for future olfactory CDM research which can utilize the benefits of direct presentation. PMID- 30295653 TI - An Available Technique for Preparation of New Cast MnCuNiFeZnAl Alloy with Superior Damping Capacity and High Service Temperature. AB - Manganese (Mn)-copper (Cu)-based alloys have been found to have damping capacity and can be used to reduce harmful vibrations and noise effectively. M2052 (Mn 20Cu-5Ni-2Fe, at%) is an important branch of Mn-Cu-based alloys, which possesses both excellent damping capacity and processability. In recent decades, lots of studies have been carried out on the performance optimization of M2052, improving the damping capacity, mechanical properties, corrosion resistance, and service temperature, etc. The major methods of performance optimization are alloying, heat treatment, pretreatment, and different ways of molding etc., among which alloying, as well as adopting a reasonable heat treatment, is the simplest and most effective method to obtain perfect and comprehensive performance. To obtain the M2052 alloy with excellent performance for casting molding, we propose to add Zn and Al to the MnCuNiFe alloy matrix and use a variety of heat treatment methods for a comparison in the microstructure, damping capacity, and service temperature. Thus, a new type of cast-aged Mn-22.68Cu-1.89Ni-1.99Fe-1.70Zn-6.16Al (at.%) alloy with superior damping capacity and high service temperature is obtained by an optimized heat treatment method. Compared with the forging technique, cast molding is simpler and more efficient, and the damping capacity of this as-cast alloy is excellent. Therefore, there is a suitable reason to think that it is a good choice for engineering applications. PMID- 30295654 TI - An Efficient Strategy for Generating Tissue-specific Binary Transcription Systems in Drosophila by Genome Editing. AB - Binary transcription systems are powerful genetic tools widely used for visualizing and manipulating cell fate and gene expression in specific groups of cells or tissues in model organisms. These systems contain two components as separate transgenic lines. A driver line expresses a transcriptional activator under the control of tissue-specific promoters/enhancers, and a reporter/effector line harbors a target gene placed downstream to the binding site of the transcription activator. Animals harboring both components induce tissue-specific transactivation of a target gene expression. Precise spatiotemporal expression of the gene in targeted tissues is critical for unbiased interpretation of cell/gene activity. Therefore, developing a method for generating exclusive cell/tissue specific driver lines is essential. Here we present a method to generate highly tissue-specific targeted expression system by employing a "Clustered Regularly Interspaced Short Palindromic Repeat/CRISPR-associated" (CRISPR/Cas)-based genome editing technique. In this method, the endonuclease Cas9 is targeted by two chimeric guide RNAs (gRNA) to specific sites in the first coding exon of a gene in the Drosophila genome to create double-strand breaks (DSB). Subsequently, using an exogenous donor plasmid containing the transactivator sequence, the cell autonomous repair machinery enables homology-directed repair (HDR) of the DSB, resulting in precise deletion and replacement of the exon with the transactivator sequence. The knocked-in transactivator is expressed exclusively in cells where the cis-regulatory elements of the replaced gene are functional. The detailed step-by-step protocol presented here for generating a binary transcriptional driver expressed in Drosophila fgf/branchless-producing epithelial/neuronal cells can be adopted for any gene- or tissue-specific expression. PMID- 30295655 TI - Highly Sensitive and Quantitative Detection of Proteins and Their Isoforms by Capillary Isoelectric Focusing Method. AB - Immunoblotting has become a routine technique in many laboratories for protein characterization from biological samples. The following protocol provides an alternative strategy, capillary isoelectric focusing (cIEF), with many advantages compared to conventional immunoblotting. This is an antibody-based, automated, rapid, and quantitative method in which a complete western blotting procedure takes place inside an ultrathin capillary. This technique does not require a gel to transfer to a membrane, stripping of blots, or x-ray films, which are typically required for conventional immunoblotting. Here, proteins are separated according to their charge (isoelectric point; pI), using less than a microliter (400 nL) of total protein lysate. After electrophoresis, proteins are immobilized onto the capillary walls by ultraviolet light treatment, followed by primary and secondary (horseradish peroxidase (HRP) conjugated) antibody incubation, whose binding is detected through enhanced chemiluminescence (ECL), generating a light signal that can be captured and recorded by a charge-coupled device (CCD) camera. The digital image can be analyzed and quantified (peak area) using software. This high throughput procedure can handle 96 samples at a time; is highly sensitive, with protein detection in the picogram range; and produces highly reproducible results because of automation. All of these aspects are extremely valuable when the quantity of samples (e.g., tissue samples and biopsies) is a limiting factor. The technique has wider applications as well, including screening of drugs or antibodies, biomarker discovery, and diagnostic purposes. PMID- 30295656 TI - Application of Design Aspects in Uniaxial Loading Machine Development. AB - In terms of accurate and precise mechanical testing, machines run the continuum. Whereas commercial platforms offer excellent accuracy, they can be cost prohibitive, often priced in the $100,000 - $200,000 price range. At the other extreme are stand-alone manual devices that often lack repeatability and accuracy (e.g., a manual crank device). However, if a single use is indicated, it is over engineering to design and machine something overly elaborate. Nonetheless, there are occasions where machines are designed and built in-house to accomplish a motion not attainable with the existing machines in the laboratory. Described in detail here is one such device. It is a loading platform that enables pure uniaxial loading. Standard loading machines typically are biaxial in that linear loading occurs along the axis and rotary loading occurs about the axis. During testing with these machines, a load is applied to one end of the specimen while the other end remains fixed. These systems are not capable of conducting pure axial testing in which tension/compression is applied equally to the specimen ends. The platform developed in this paper enables the equal and opposite loading of specimens. While it can be used for compression, here the focus is on its use in pure tensile loading. The device incorporates commercial load cells and actuators (movers) and, as is the case with machines built in-house, a frame is machined to hold the commercial parts and fixtures for testing. PMID- 30295658 TI - 'Boden Food Plate': Novel Interactive Web-based Method for the Assessment of Dietary Intake. AB - Different methods can be used in research to assess dietary intake, many of which are still paper-based. Written estimated food diaries are often utilized in clinical trials, despite being a burden for both study participants and researchers. This method requires participant literacy, it is time consuming, labor intensive, and can easily lead to under-reporting. With advancements in technology, there is a growing interest in electronic diaries that automate the dietary assessment process. These are focused on improving accuracy, reducing both time and cost and providing users with a visual and more enjoyable experience. The methodology presented here aimed to validate the 'Boden Food Plate', a novel web-based platform for self-recording of food and drink items, compared to a traditional estimated food diary. The application was also rated on a satisfaction scale by study participants using a paper-based questionnaire. Sixty-seven participants completed the dietary measures on both the three-day electronic and paper food diaries. For the analysis, only dietary data completed at both study time points (baseline and week six) was utilized. Despite small mean differences between dietary data collection methods, Bland Altman analysis showed fairly wide 95% limits of agreement between the electronic platform and the written estimated food diary and there were few cases which did not fall within the 95% confidence intervals. Overall, participants found the electronic food diary to be more fun than the paper method and as easy to use as hard copy diaries. The new platform has potential as a self-recording tool for the collection of dietary data, particularly when utilized in clinical trial settings. However, further validation studies are needed to improve the validity of this novel electronic dietary data collection tool. PMID- 30295659 TI - Isolation and Fluorescence Imaging for Single-particle Reconstruction of Chlamydomonas Centrioles. AB - Centrioles are large macromolecular assemblies important for the proper execution of fundamental cell biological processes such as cell division, cell motility, or cell signaling. The green algae Chlamydomonas reinhardtii has proven to be an insightful model in the study of centriole architecture, function, and protein composition. Despite great advances toward understanding centriolar architecture, one of the current challenges is to determine the precise localization of centriolar components within structural regions of the centriole in order to better understand their role in centriole biogenesis. A major limitation lies in the resolution of fluorescence microscopy, which complicates the interpretation of protein localization in this organelle with dimensions close to the diffraction limit. To tackle this question, we are providing a method to purify and image a large number of C. reinhardtii centrioles with different orientations using super-resolution microscopy. This technique allows further processing of data through fluorescent single-particle averaging (Fluo-SPA) owing to the large number of centrioles acquired. Fluo-SPA generates averages of stained C. reinhardtii centrioles in different orientations, thus facilitating the localization of distinct proteins in centriolar sub-regions. Importantly, this method can be applied to image centrioles from other species or other large macromolecular assemblies.

AB - Participation in organized sports makes a significant contribution to youth development, but places youth at a higher risk for sustaining a concussion. To date, return-to-activity decision-making has been anchored in the monitoring of self-reported concussion symptoms and neurocognitive testing. However, multi modal assessments that corroborate objective physiological measures with traditional subjective symptom reporting are needed and can be valuable. Heart rate variability (HRV) is a non-invasive physiological indicator of the autonomic nervous system, capturing the reciprocal interplay between the sympathetic and parasympathetic nervous systems. There is a dearth of literature exploring the effect of concussion on HRV in youth athletes, and developmental differences preclude the application of adult findings to a pediatric population. Further, the current state of HRV methodology has primarily included short-term (5-15 min) recordings, by using resting state or short-term physical exertion testing to elucidate changes following concussion. The novelty in utilizing a 24 h recording methodology is that it has the potential to capture natural variation in autonomic function, directly related to the activities a youth athlete performs on a regular basis. Within a prospective, longitudinal research setting, this novel approach to quantifying autonomic function can provide important information regarding the recovery trajectory, alongside traditional self-report symptom measures. Our objectives regarding a 24 h recording methodology were to (1) evaluate the physiological effects of a concussion in youth athletes, and (2) describe the trajectory of physiological change, while considering the resolution of self-reported post-concussion symptoms. To achieve these objectives, non invasive sensor technology was implemented. The raw beat-to-beat time intervals captured can be transformed to derive time domain and frequency domain measures, which reflect an individual's ability to adapt and be flexible to their ever changing environment. By using non-invasive heart rate technology, autonomic function can be quantified outside of a traditional controlled research setting.

AB - The goal of this method is to determine the chemical composition and electrical resistivity of cementitious pore solution expressed from a fresh paste sample. The pore solution is expressed from a fresh paste sample using a pressurized nitrogen gas system. The pore solution is then immediately transferred to a syringe to minimize evaporation and carbonation. After that, assembled testing containers are used for the X-ray fluorescence (XRF) measurement. These containers consist of two concentric plastic cylinders and a polypropylene film which seals one of the two open sides. The pore solution is added into the container immediately prior to the XRF measurement. The XRF is calibrated to detect the main ionic species in the pore solution, in particular, sodium (Na+), potassium (K+), calcium (Ca2+), and sulfide (S2-), to calculate sulfate (SO42-) using stoichiometry. The hydroxides (OH-) can be calculated from a charge balance. To calculate the electrical resistivity of the solution, the concentrations of the main ionic species and a model by Snyder et al. are used. The electrical resistivity of the pore solution can be used, along with the electrical resistivity of concrete, to determine the formation factor of concrete. XRF is a potential alternative to current methods to determine the composition of pore solution, which can provide benefits in terms of reduction in time and costs. PMID- 30295660 TI - The Combined Use of Transcranial Direct Current Stimulation and Robotic Therapy for the Upper Limb. AB - Neurologic disorders such as stroke and cerebral palsy are leading causes of long term disability and can lead to severe incapacity and restriction of daily activities due to lower and upper limb impairments. Intensive physical and occupational therapy are still considered main treatments, but new adjunct therapies to standard rehabilitation that may optimize functional outcomes are being studied. Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique that polarizes underlying brain regions through the application of weak direct currents through electrodes on the scalp, modulating cortical excitability. Increased interest in this technique can be attributed to its low cost, ease of use, and effects on human neural plasticity. Recent research has been performed to determine the clinical potential of tDCS in diverse conditions such as depression, Parkinson's disease, and motor rehabilitation after stroke. tDCS helps enhance brain plasticity and seems to be a promising technique in rehabilitation programs. A number of robotic devices have been developed to assist in the rehabilitation of upper limb function after stroke. The rehabilitation of motor deficits is often a long process requiring multidisciplinary approaches for a patient to achieve maximum independence. These devices do not intend to replace manual rehabilitation therapy; instead, they were designed as an additional tool to rehabilitation programs, allowing immediate perception of results and tracking of improvements, thus helping patients to stay motivated. Both tDSC and robot-assisted therapy are promising add-ons to stroke rehabilitation and target the modulation of brain plasticity, with several reports describing their use to be associated with conventional therapy and the improvement of therapeutic outcomes. However, more recently, some small clinical trials have been developed that describe the associated use of tDCS and robot-assisted therapy in stroke rehabilitation. In this article, we describe the combined methods used in our institute for improving motor performance after stroke. PMID- 30295662 TI - Fabrication of Three-Dimensional Graphene-Based Polyhedrons via Origami-Like Self Folding. AB - The assembly of two-dimensional (2D) graphene into three-dimensional (3D) polyhedral structures while preserving the graphene's excellent inherent properties has been of great interest for the development of novel device applications. Here, fabrication of 3D, microscale, hollow polyhedrons (cubes) consisting of a few layers of 2D graphene or graphene oxide sheets via an origami like self-folding process is described. This method involves the use of polymer frames and hinges, and aluminum oxide/chromium protection layers that reduce tensile, spatial, and surface tension stresses on the graphene-based membranes when the 2D nets are transformed into 3D cubes. The process offers control of the size and shape of the structures as well as parallel production. In addition, this approach allows the creation of surface modifications by metal patterning on each face of the 3D cubes. Raman spectroscopy studies show the method allows the preservation of the intrinsic properties of the graphene-based membranes, demonstrating the robustness of our method. PMID- 30295663 TI - Negative Additive Manufacturing of Complex Shaped Boron Carbides. AB - Boron carbide (B4C) is one of the hardest materials in existence. However, this attractive property also limits its machineability into complex shapes for high wear, high hardness, and lightweight material applications such as armors. To overcome this challenge, negative additive manufacturing (AM) is employed to produce complex geometries of boron carbides at various length scales. Negative AM first involves gelcasting a suspension into a 3D-printed plastic mold. The mold is then dissolved away, leaving behind a green body as a negative copy. Resorcinol-formaldehyde (RF) is used as a novel gelling agent because unlike traditional hydrogels, there is little to no shrinkage, which allows for extremely complex molds to be used. Furthermore, this gelling agent can be pyrolyzed to leave behind ~50 wt% carbon, which is a highly effective sintering aid for B4C. Due to this highly homogenous distribution of in situ carbon within the B4C matrix, less than 2% porosity can be achieved after sintering. This protocol highlights in detail the methodology for creating near fully dense boron carbide parts with highly complex geometries. PMID- 30295664 TI - Transcranial Direct Current Stimulation (tDCS) in Mice. AB - Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulation technique proposed as an alternative or complementary treatment for several neuropsychiatric diseases. The biological effects of tDCS are not fully understood, which is in part explained due to the difficulty in obtaining human brain tissue. This protocol describes a tDCS mouse model that uses a chronically implanted electrode allowing the study of the long-lasting biological effects of tDCS. In this experimental model, tDCS changes the cortical gene expression and offers a prominent contribution to the understanding of the rationale for its therapeutic use. PMID- 30295665 TI - Repressing Gene Transcription by Redirecting Cellular Machinery with Chemical Epigenetic Modifiers. AB - Regulation of chromatin compaction is an important process that governs gene expression in higher eukaryotes. Although chromatin compaction and gene expression regulation are commonly disrupted in many diseases, a locus-specific, endogenous, and reversible method to study and control these mechanisms of action has been lacking. To address this issue, we have developed and characterized novel gene-regulating bifunctional molecules. One component of the bifunctional molecule binds to a DNA-protein anchor so that it will be recruited to an allele specific locus. The other component engages endogenous cellular chromatin modifying machinery, recruiting these proteins to a gene of interest. These small molecules, called chemical epigenetic modifiers (CEMs), are capable of controlling gene expression and the chromatin environment in a dose-dependent and reversible manner. Here, we detail a CEM approach and its application to decrease gene expression and histone tail acetylation at a Green Fluorescent Protein (GFP) reporter located at the Oct4 locus in mouse embryonic stem cells (mESCs). We characterize the lead CEM (CEM23) using fluorescent microscopy, flow cytometry, and chromatin immunoprecipitation (ChIP), followed by a quantitative polymerase chain reaction (qPCR). While the power of this system is demonstrated at the Oct4 locus, conceptually, the CEM technology is modular and can be applied in other cell types and at other genomic loci. PMID- 30295666 TI - Synthesis and Characterization of Placental Chondroitin Sulfate A (plCSA) Targeting Lipid-Polymer Nanoparticles. AB - An effective cancer therapeutic method reduces and eliminates tumors with minimal systemic toxicity. Actively targeting nanoparticles offer a promising approach to cancer therapy. The glycosaminoglycan placental chondroitin sulfate A (plCSA) is expressed on a wide range of cancer cells and placental trophoblasts, and malarial protein VAR2CSA can specifically bind to plCSA. A reported placental chondroitin sulfate A binding peptide (plCSA-BP), derived from malarial protein VAR2CSA, can also specifically bind to plCSA on cancer cells and placental trophoblasts. Hence, plCSA-BP-conjugated nanoparticles could be used as a tool for targeted drug delivery to human cancers and placental trophoblasts. In this protocol, we describe a method to synthesize plCSA-BP-conjugated lipid-polymer nanoparticles loaded with doxorubicin (plCSA-DNPs); the method consists of a single sonication step and bioconjugate techniques. In addition, several methods for characterizing plCSA-DNPs, including determining their physicochemical properties and cellular uptake by placental choriocarcinoma (JEG3) cells, are described. PMID- 30295667 TI - Simultaneous Cryosectioning of Multiple Rodent Brains. AB - Histology and immunohistochemistry are routine methods of analysis to visualize microscopic anatomy and localize proteins within biological tissue. In neuroscience, as well as a plethora of other scientific fields, these techniques are used. Immunohistochemistry can be done on slide mounted tissue or free floating sections. Preparing slide-mounted samples is a time intensive process. The following protocol for a technique, called the Megabrain, reduced the time taken to cryosection and mount brain tissue by up to 90% by combining multiple brains into a single frozen block. Furthermore, this technique reduced variability seen between staining rounds, in a large histochemical study. The current technique has been optimized for using rodent brain tissue in downstream immunohistochemical analyses; however, it can be applied to different scientific fields that use cryosectioning. PMID- 30295668 TI - Identification, Histological Characterization, and Dissection of Mouse Prostate Lobes for In Vitro 3D Spheroid Culture Models. AB - Genetically engineered mouse models (GEMMs) serve as effective pre-clinical models for investigating most types of human cancers, including prostate cancer (PCa). Understanding the anatomy and histology of the mouse prostate is important for the efficient use and proper characterization of such animal models. The mouse prostate has four distinct pairs of lobes, each with their own characteristics. This article demonstrates the proper method of dissection and identification of mouse prostate lobes for disease analysis. Post-dissection, the prostate cells can be further cultured in vitro for mechanistic understanding. Since mouse prostate primary cells tend to lose their normal characteristics when cultured in vitro, we outline here a method for isolating the cells and growing them as 3D spheroid cultures, which is effective for preserving the physiological characteristics of the cells. These 3D cultures can be used for analyzing cell morphology and behavior in near-physiological conditions, investigating altered levels and localizations of key proteins and pathways involved in the development and progression of a disease, and looking at responses to drug treatments. PMID- 30295669 TI - A Metadata Extraction Approach for Clinical Case Reports to Enable Advanced Understanding of Biomedical Concepts. AB - Clinical case reports (CCRs) are a valuable means of sharing observations and insights in medicine. The form of these documents varies, and their content includes descriptions of numerous, novel disease presentations and treatments. Thus far, the text data within CCRs is largely unstructured, requiring significant human and computational effort to render these data useful for in depth analysis. In this protocol, we describe methods for identifying metadata corresponding to specific biomedical concepts frequently observed within CCRs. We provide a metadata template as a guide for document annotation, recognizing that imposing structure on CCRs may be pursued by combinations of manual and automated effort. The approach presented here is appropriate for organization of concept related text from a large literature corpus (e.g., thousands of CCRs) but may be easily adapted to facilitate more focused tasks or small sets of reports. The resulting structured text data includes sufficient semantic context to support a variety of subsequent text analysis workflows: meta-analyses to determine how to maximize CCR detail, epidemiological studies of rare diseases, and the development of models of medical language may all be made more realizable and manageable through the use of structured text data. PMID- 30295670 TI - Manufacturing Abdominal Aorta Hydrogel Tissue-Mimicking Phantoms for Ultrasound Elastography Validation. AB - Ultrasound (US) elastography, or elasticity imaging, is an adjunct imaging technique that utilizes sequential US images of soft tissues to measure the tissue motion and infer or quantify the underlying biomechanical characteristics. For abdominal aortic aneurysms (AAA), biomechanical properties such as changes in the tissue's elastic modulus and estimates of the tissue stress may be essential for assessing the need for the surgical intervention. Abdominal aortic aneurysms US elastography could be a useful tool to monitor AAA progression and identify changes in biomechanical properties characteristic of high-risk patients. A preliminary goal in the development of an AAA US elastography technique is the validation of the method using a physically relevant model with known material properties. Here we present a process for the production of AAA tissue-mimicking phantoms with physically relevant geometries and spatially modulated material properties. These tissue phantoms aim to mimic the US properties, material modulus, and geometry of the abdominal aortic aneurysms. Tissue phantoms are made using a polyvinyl alcohol cryogel (PVA-c) and molded using 3D printed parts created using computer aided design (CAD) software. The modulus of the phantoms is controlled by altering the concentration of PVA-c and by changing the number of freeze-thaw cycles used to polymerize the cryogel. The AAA phantoms are connected to a hemodynamic pump, designed to deform the phantoms with the physiologic cyclic pressure and flows. Ultra sound image sequences of the deforming phantoms allowed for the spatial calculation of the pressure normalized strain and the identification of mechanical properties of the vessel wall. Representative results of the pressure normalized strain are presented. PMID- 30295671 TI - A de novo transcriptome assembly of the zebra bullhead shark, Heterodontus zebra. AB - Although cartilaginous fishes have played crucial roles in various fields, including evolutionary biology, marine ecology, bioresources, and aquarium exhibitions, molecular information for these species is poorly available. The present study reports a transcriptome assembly from an embryo of the zebra bullhead shark (Heterodontus zebra), produced by paired-end RNA sequencing. Transcriptome data is generated with a de novo transcriptome assembler, Trinity. Amino acid sequences are predicted from the assemblies, using TransDecoder. Because cartilaginous fishes serve as the outgroup of bony vertebrates, the data would contribute to comparative analyses of a various biological fields. In addition, this study would be useful for conservation biology, such as transcriptome-based population genetics. PMID- 30295672 TI - Comprehensive identification of peptides in tandem mass spectra using an efficient open search engine. AB - We present a sequence-tag-based search engine, Open-pFind, to identify peptides in an ultra-large search space that includes coeluting peptides, unexpected modifications and digestions. Our method detects peptides with higher precision and speed than seven other search engines. Open-pFind identified 70-85% of the tandem mass spectra in four large-scale datasets and 14,064 proteins, each supported by at least two protein-unique peptides, in a human proteome dataset. PMID- 30295673 TI - Nondestructive, base-resolution sequencing of 5-hydroxymethylcytosine using a DNA deaminase. AB - Here we present APOBEC-coupled epigenetic sequencing (ACE-seq), a bisulfite-free method for localizing 5-hydroxymethylcytosine (5hmC) at single-base resolution with low DNA input. The method builds on the observation that AID/APOBEC family DNA deaminase enzymes can potently discriminate between cytosine modification states and exploits the non-destructive nature of enzymatic, rather than chemical, deamination. ACE-seq yielded high-confidence 5hmC profiles with at least 1,000-fold less DNA input than conventional methods. Applying ACE-seq to generate a base-resolution map of 5hmC in tissue-derived cortical excitatory neurons, we found that 5hmC was almost entirely confined to CG dinucleotides. The whole-genome map permitted cytosine, 5-methylcytosine (5mC) and 5hmC to be parsed and revealed genomic features that diverged from global patterns, including enhancers and imprinting control regions with high and low 5hmC/5mC ratios, respectively. Enzymatic deamination overcomes many challenges posed by bisulfite based methods, thus expanding the scope of epigenome profiling to include scarce samples and opening new lines of inquiry regarding the role of cytosine modifications in genome biology. PMID- 30295675 TI - Embryonic transcriptome sequencing of the ocellate spot skate Okamejei kenojei. AB - Chondrichthyans (cartilaginous fishes) exhibit highly variable reproductive styles, categorized as viviparity and oviparity. Among these, species with oviparity provide an enormous potential of molecular experimentation with stable sample supply which does not demand the sacrifices of live mothers. Cartilaginous fishes are divided into two subclasses, chimaeras (Holocephali) and elasmobranchs (Elasmobranchii), and the latter consists of two monophyletic groups, Batoidea (rays, skates and torpedoes) and Selachimorpha (sharks). Here we report transcriptome assemblies of the ocellate spot skate Okamejei kenojei, produced by strand-specific RNA-seq of its embryonic tissues. We obtained a total of 325 million illumina short reads from libraries prepared using four different tissue domains and assembled them all together. Our assembly result confirmed the species authenticity and high continuity of contig sequences. Also, assessment of its coverage of pre-selected one-to-one orthologs supported high diversity of transcripts in the assemblies. Our products are expected to provide a basis of comparative molecular studies encompassing other chondrichthyan species with emerging genomic and transcriptomic sequence information. PMID- 30295676 TI - Role of food-drug interactions in neurological and psychological diseases. AB - Given that foods and nutrients have been shown to influence the pharmacokinetics of drugs, drugs may cause changes in the nutritional status of patients and their response to a given drug. Food-drug interactions are particularly relevant for drugs used to treat neurological and psychological diseases. This review provides an overview of food-drug interaction in the treatment of neurological and psychological diseases. A literature search was carried out by collecting data from different reviews, reports, and original articles on general or specific drug interactions with food, in patients with a variety of neurological and psychological diseases. Based on our review, we found that food-drug interactions may alter the expected impact of drug, or cause the development of a drug toxicity. Nutritional status of the patients may also be affected, particularly a change in body weight caused by a change appetite. Metabolism, absorption, and excretion of foods may also be altered, and nutritional insufficiencies may occur. Recent studies show that diet can have a strong influence on gut microbiota and thus, alter drug pharmacokinetics. Therefore, microbiota alterations should also be considered while assessing food-drug interactions. Knowledge of food-drug interactions is critical for improving health of patients with neurological and psychological diseases, and also for improving effectiveness of treatments. PMID- 30295674 TI - Rhizosphere microbiome structure alters to enable wilt resistance in tomato. AB - Tomato variety Hawaii 7996 is resistant to the soil-borne pathogen Ralstonia solanacearum, whereas the Moneymaker variety is susceptible to the pathogen. To evaluate whether plant-associated microorganisms have a role in disease resistance, we analyzed the rhizosphere microbiomes of both varieties in a mesocosm experiment. Microbiome structures differed between the two cultivars. Transplantation of rhizosphere microbiota from resistant plants suppressed disease symptoms in susceptible plants. Comparative analyses of rhizosphere metagenomes from resistant and susceptible plants enabled the identification and assembly of a flavobacterial genome that was far more abundant in the resistant plant rhizosphere microbiome than in that of the susceptible plant. We cultivated this flavobacterium, named TRM1, and found that it could suppress R. solanacearum disease development in a susceptible plant in pot experiments. Our findings reveal a role for native microbiota in protecting plants from microbial pathogens, and our approach charts a path toward the development of probiotics to ameliorate plant diseases. PMID- 30295677 TI - Charcot-Marie-Tooth type 1A drug therapies: role of adenylyl cyclase activity and G-protein coupled receptors in disease pathomechanism. AB - Charcot-Marie-Tooth type 1A (CMT1A) is a dysmyelinating disease of the peripheral nervous system that results in a slow progressive weakening and wasting of the distal muscles of the upper and lower limbs. Despite extensive research and clinical trials there is still no treatment for CMT1A that results in complete neurological improvement. Recent studies investigating various pharmacological modulators of adenylyl cyclase activity, including ascorbic acid and ligands of G protein-coupled receptors (GPCRs), provide hope for future treatments of this type of hereditary motor and sensory neuropathy. A review of mechanisms of action of several compounds tested for CMT1A in pre-clinical and clinical studies ascorbic acid, onapristone, PXT3003 (baclofen, naltrexone, and sorbitol), and ADX71441, very clearly indicates an important role for adenylyl cyclase activity and GPCRs in the pathomechanism of the disease. Metabotropic gamma-aminobutyric acid receptors (GABABR), subtype mu (MU) opioid receptors (MOR), and muscarinic acetylcholine receptors (mACh) appear to be particularly significant in both pathogenesis and treatment, and their activation may exert a similar and synergistic effect on the physiology of Schwann cells as well as neurons. These receptors participate in proliferation and differentiation of Schwann cells and influence excitatory transmission in neurons. We also hypothesize that onapristone might act through a non-classical mechanism via membrane progesterone receptor (mPR) and cAMP signaling. This review endeavors to outline a pathway leading inversely from therapy to an indispensable role for adenylyl cyclase activity and GPCRs in the modulation of dosage sensitive peripheral myelin protein (PMP22) gene expression. PMID- 30295678 TI - The role of DSCAM in the regulation of synaptic plasticity: possible involvement in neuropsychiatric disorders. AB - Synaptic plasticity simply put, is the activity-dependent modification of the strength or efficacy of synaptic transmission in the network of synapses in the brain. The role of synaptic plasticity in disease is an active area of research. Changes in plasticity translate to the release of neurotransmitters at the synapse and subsequently, the way humans see the world. It is known that neuropsychiatric disorders such as depression, posttraumatic stress disorder (PTSD), and Alzheimer's disease (AD) are related to pathological changes in dynamic processes in synapses, dialogue between neurons, and finally, changes in overall plasticity. To find a cure for these plasticity related diseases, it is imperative that we understand the precise mechanisms that perturb the homeostatic balance leading to the disease state. The aim of this review is to present what is currently known about DSCAM (Down Syndrome Cell Adhesion Molecule) a protein that is directly connected to pathological changes in synaptic plasticity. The review will present information on DSCAM and how it is connected to glutamate (Glu) and gamma-Aminobutyric acid (GABA) neurotransmission pathways. Finally, the review throws some light on the possible involvement of DSCAM in a spectrum of psychiatric disorders apart from Down syndrome (DS). PMID- 30295679 TI - Hindlimb suspension-induced cell apoptosis in the posterior parietal cortex and lateral geniculate nucleus: corresponding changes in c-Fos protein and the PI3K/Akt signaling pathway. AB - Recent physiological studies indicate that weightlessness reliably alters ocular structure and function, as well as the ability to process visual-spatial information. The posterior parietal cortex (PPC) and lateral geniculate nucleus (LGN) are two key brain areas implicated in the processing of visual-spatial information. Here, we used the modified tail-suspension rat model to simulate the physiological effects of microgravity. Rats were divided into four groups, which exposed to the simulated microgravity environment for 0 (Control group), 7, 14, or 28 days. We found a significant increase in cellular apoptosis in the PPC and the LGN after 7 days of simulated microgravity. In addition, there was an increase in expression of c-Fos protein in the PPC, and a repression of the PI3K/Akt signaling pathway in the LGN after 7 days. Based on these results, we conclude that short-term simulated microgravity may induce cell apoptosis in the PPC and LGN, and reflect a neural adaptive process to accommodate a microgravity environment. PMID- 30295680 TI - Effects of PINK1 mutation on synapses and behavior in the brain of Drosophila melanogaster. AB - Mutations in the PINK1 gene are responsible for typical symptoms of Parkinson's disease. Using Drosophila melanogaster mutant PINK1B9 and after PINK1 silencing with RNAi using transgenic lines, we observed defects in synapses and behavior. The lack or reduced expression of PINK1 prolonged sleep during the day (nap) and decreased the total locomotor activity during 24 h, in addition to a decrease in climbing ability and a reduced lifespan. In the brain, PINK1 mutants had a lower level of Bruchpilot (BRP), a presynaptic scaffolding protein that is crucial for neurotransmission in all type of synapses in Drosophila. In addition, other proteins that are involved in synaptic transmission; Rab5, Syntaxin and Wishful Thinking were also decreased in abundance in mutants, except Synaptotagmin. Transmission electron microscopy (TEM) also confirmed less and abnormal synaptic vesicles at tetrad synapses in the visual system of PINK1 mutants. The lower level of BRP and longer day sleep observed was also detected in white mutants, which were examined to test the effect of the?r?nwhite background on the PINK1B9 strain. The reduced locomotor activity and longer day sleep in PINK1 mutants and after decreasing the PINK1 level in neurons seem to be correlated with a decrease in mitochondria number during the day, when they normally peak, and with impaired synaptic transmission. PMID- 30295681 TI - Effects of extensive amygdaloid lesions on conditioned taste aversion in rats. AB - The role of the amygdala in the acquisition of conditioned taste aversion (CTA) is unclear. The lesion studies that have explored specific nuclei of the amygdala point to a probable involvement of the basolateral amygdala, but it remains unclear whether the function of the amygdala in CTA is limited to the activity of the basolateral amygdala. In the current study, extensive bilateral lesions of the amygdala were performed in Wistar rats to explore if the destruction of the amygdala affects the acquisition of CTA, as has been reported with selective lesions of the basolateral amygdala. The magnitude of the taste aversion of animals with extensive lesions of the amygdala was compared with those of animals with similar lesions of the striatum (a structure apparently unrelated to CTA) and animals without lesions. Taste aversion was analyzed by the one-bottle test and two-bottle choice test. The results of the one-bottle test indicated that amygdaloid lesions significantly reduced the magnitude of taste aversion compared with that of animals without lesions. Animals with lesions of the amygdala also showed a greater preference for the conditioned taste stimulus, but this preference did not reach statistical significance. Besides the effect on CTA, animals with amygdaloid lesions showed no evidence of taste neophobia on the day of conditioning. These findings suggest that amygdaloid lesions may affect CTA by disrupting the perception of novelty during conditioning in a manner similar to the effect reported with basolateral lesions. PMID- 30295683 TI - Testosterone enhancement during pregnancy influences social coping and gene expression of oxytocin and vasopressin in the brain of adult rats. AB - Steroid hormones are important mediators of prenatal maternal effects and play an important role in fetal programming. The aim of our study was to investigate how testosterone enhancement during pregnancy influences neurobehavioral aspects of social coping of rat offspring in adulthood. Pregnant rat dams were exposed to depot form of testosterone during the last third of pregnancy (i.e., beginning on the 14th day of pregnancy). Their adult offspring were later tested in a social interaction test and expression of oxytocin and arginine-vasopressin mRNA in the hypothalamic nuclei was evaluated. Our research showed that prenatal exposure to higher levels of testosterone activated socio-cohesive and socio-aversive interactions, but only in males. The testosterone-exposed group also showed decreased oxytocin mRNA expression in the supraoptic and paraventricular nuclei of the hypothalamus, and increased arginine-vasopressin mRNA expression in the supraoptic and suprachiasmatic nuclei as compared to controls. However, we did not observe any sex differences in the expression of oxytocin and arginine vasopressin mRNA in these regions. Our findings show that testosterone enhancement in pregnancy could have long-lasting effects on oxytocin and arginine vasopressin levels in the brain of adult animals, but lead to changes in behavioral aspects of coping strategies only in males. PMID- 30295682 TI - Afferent projections of the subthalamic nucleus in the rat: emphasis on bilateral and interhemispheric connections. AB - The subthalamic nucleus (STN) is important for normal movement as well as in movement disorders. The STN is a target nuclei in patients with advanced Parkinson's disease (PD). Deep brain stimulation (DBS) is a standard surgical treatment for PD. Although DBS results in a significant reduction in motor disability, several negative side effects have been reported. Thus, to understand the side effects of DBS the connection of the STN should be well known. Therefore, the present study aims to re-examine the STN with an emphasis on poorly- or un-documented connections. Furthermore, the bilateral and interhemispheric connections of the STN are evaluated. Fifteen male albino rats received injections of Fluoro-Gold retrograde and biotinylated dextran amine anterograde tracers into the STN. Following a 7-10 day survival period, the animals were processed according to the relevant protocol for each tracer. The present study demonstrates ipsilateral connections of the STN with cortical regions (i.e., infralimbic, cingulate, frontal, piriform, primary motor, primary sensory, insular and retrosplenial cortices), the endopiriform nucleus, basal ganglia related structures (i.e., caudate putamen, globus pallidus, ventral pallidum, nucleus accumbens, claustrum and substantia innominata) and the deep cerebellar nuclei (i.e., lateral, anterior interposed). Bilateral connections of the STN were observed with limbic (amygdala, bed nucleus of stria terminalis), hypothalamic (ventromedial, posterior, anterior, lateral and mammillary) thalamic (thalamic reticular nucleus), epithalamic (habenular nucleus), and brainstem structures (superior colliculus, substantia nigra, spinal nucleus of the trigeminal nerve, red nucleus, dorsal raphe nucleus, pedunculopontine tegmental nuclei). Interhemispheric connections between left and right STN were also observed. The present study fills important gaps in connectivity of the STN. In particular, we report STN connectivity with cortical areas (i.e., piriform, endopiriform and insular), claustrum, hypothalamic, thalamic reticular, cerebellar, habenular, trigeminal, red, cuneate and gracile nuclei and substantia innominate. These connections, which have not been previously described or poorly described, provide new routes that can alter the conceptual architecture of the basal ganglia circuitry and may modify our view of the functional identity of the STN. PMID- 30295684 TI - The use of MR-less MNI based neuronavigation for 10 Hz rTMS depression therapy: electrophysiological and clinical implications. AB - Repetitive transcranial magnetic stimulation (rTMS) is a popular and effective treatment for drug resistant depression. However, there is considerable variability in clinical outcomes, in previous studies and between patients. Because of high requirements for the use of fMRI based neuronavigation, many practitioners of rTMS still choose to use a standard 5 cm rule for rTMS coil placement which leads to large variations in which brain regions are being stimulated. We decided to test the possibilities of a MNI based MR-less neuronavigation system in rTMS depression treatment, by comparing the physiological effects and clinical outcomes of 3 distinct stimulation targets. Forty-six patients (thirty-three female, thirteen male) from the Republican Vilnius psychiatric hospital, all with drug resistant depressive disorder, participated in the study. All patients received high frequency (10 Hz) stimulation for 10 to 15 daily rTMS sessions. However, before the treatment they were randomly sorted into 3 groups according to stimulation target in MNI map: Group 1 received rTMS at point -40; 48; 35; Group 2 received rTMS at point -46; 45; 38; Group 3 received rTMS at point -38; 44; 26. Electroencephalography (EEG) recordings and clinical tests were obtained the day before the rTMS course and after the last session. There were some notable differences in physiological changes between the groups, with the largest EEG band spectral power increases found in Group 1 patients and the lowest in Group 2 patients. There was a significantly larger decrease of the Hamilton Depression Rating Scale (HAM-D) scores in the Group 3 (66.94%) compared to Group 1 (57.52%) and Group 2 (56.02%). This suggests it is possible to achieve higher clinical efficacy and less physiological impact on the brain when using different targets in a neuronavigated MNI based MR-less rTMS system. PMID- 30295685 TI - MMP-3 deficiency does not influence the length and number of CA1 dendrites of hippocampus of adult mice. AB - Over the past two decades, metalloproteinases (MMPs), including MMP-2, MMP-3, and MMP-9, have been implicated as important players in mechanisms underlying various forms of neuroplasticity. In particular, MMP-3 was found to be involved in both cognitive functions and in plasticity phenomena, but the underlying molecular mechanisms remain largely elusive. In general, it is believed that functional plasticity of neurons is associated with morphological alterations. Interestingly, MMP-9, in addition to playing a key role in synaptic plasticity, was found to affect plasticity-related spine morphology changes. Whereas the involvement of MMP-3 in shaping synapse morphology upon induction of synaptic plasticity awaits determination, it has been demostrated that MMP-3 knockout results in clearly altered apical dendrite morphology in pyramidal neurons in mouse visual cortex. Considering that the involvement of MMP-3 in synaptic plasticity has been most extensively documented for the CA1 hippocampal region, we decided to investigate whether genetic deletion of MMP-3 affects neuronal morphology in this area. To this end, we used Golgi staining to compare dendritic morphology of pyramidal neurons in the CA1 region in MMP-3-deficient and wild type mice. Surprisingly, in contrast to the results obtained in cortex, extensive analysis of dendritic morphology in the CA1 region revealed no significant differences between MMP-3 knockout and wild-type groups. These results suggest that the impact of MMP-3 on neuronal morphology may be region-specific. PMID- 30295686 TI - Polycomb repressive complex 2 binds RNA irrespective of stereochemistry. AB - The Polycomb Repressive Complex 2 (PRC2) interacts promiscuously with G quadruplex (G4) RNA structures. Herein, we tested the limit of this promiscuity by exploring the interaction of PRC2 with G4 RNAs comprised of l-ribonucleic acids (l-RNA), the enantiomer of naturally occurring d-RNA. Remarkably, we find that PRC2 binds similarly to both d- and l-G4 RNAs, suggesting that these interactions are independent of stereochemistry. Moreover, we show that d- and l RNAs bind to the same site on PRC2, enabling l-G4 RNAs to outcompete native substrates for binding. This work challenges the prevailing assumption that l oligonucleotides are "invisible" to native biology and provides a unique opportunity to develop a novel class of PRC2 inhibitors based on nuclease resistant l-RNA.

AB - Weakly emissive phosphine compounds, which contain a carbazolyl donor triarylboryl acceptor luminophore, become strongly delayed fluorescent upon changes to their oxide forms. Time-gated acquisition of the fluorescence signals of phosphine in the presence of H2O2 and a competitive fluorescence dye allow for detection of H2O2 with elimination of short-lived fluorescence noise.

AB - A method to synthesize bimetallic alloys with tunable morphologies and controlled structural defects was proposed using the characteristics of emulsions tailored by salts. AuPd and PtPd nanowire networks with abundant structural defects exhibited outstanding catalytic performances for oxidation of 5 hydroxymethylfurfural to 2,5-furandicarboxylic acid, because of the strong ability to generate radicals. PMID- 30295689 TI - A dual chemosensor for Cu2+ and Hg2+ based on a rhodamine-terminated water soluble polymer in 100% aqueous solution. AB - A novel water-soluble polymer bearing a rhodamine receptor (PEGSRh) was synthesized as a dual chemosensor for the recognition of Cu2+ and Hg2+ in 100% aqueous solution. PEGSRh not only exhibited a sensitive colorimetric response towards Cu2+ and Hg2+ but also showed a selective turn-on fluorescence response towards Hg2+ over other metal ions. The binding stoichiometry for the complexation of PEGSRh with Cu2+ and Hg2+ was confirmed to be 1 : 1 by Job plot analysis. The low detection limits were found to be 5.92 * 10-7 M for Cu2+ and 2.85 * 10-6 M for Hg2+. The responses of PEGSRh to Cu2+ and Hg2+ were both stable over wide pH ranges. In addition, the fluorescence intensity changes of PEGSRh solution by the inputs of Hg2+, Cu2+ and EDTA have been used to construct a combinational logic gate. Again, an INHIBIT logic gate was also obtained by employing Cu2+ and EDTA as the chemical inputs and the absorbance signal as the output. Moreover, test papers were prepared facilely using PEGSRh for practical on-site detection of Cu2+ and Hg2+.

PMID- 30295693 TI - Patent foramen ovale causing breathlessness and platypnoea-orthodeoxia syndrome in an older patient. AB - An 82-year-old male presented with a week's history of shortness of breath on exertion, particularly when bending to tie his shoe laces. The breathlessness worsened on standing and was relieved by lying. His oxygen saturations were noted to fluctuate based on position dropping to 82% on standing. This was suggestive of platypnoea-orthodeoxia syndrome (POS), an uncommon but potentially reversible diagnosis. As the population ages we may be more likely to see patients with persisting patent foramen ovale decompensate and develop POS.

AB - Conformational transitions in protein kinases are crucial for the biological function of these enzymes. Here, we characterize and assess conformational equilibria of the activation loop and the effect of small molecule inhibitors in the MAP kinase p38alpha. Our work experimentally revealed the existence of a two state equilibrium for p38alpha while the addition of inhibitors shifts the equilibrium between these two states. PMID- 30295694 TI - Effects of Cannabis Use and Subclinical ADHD Symptomology on Attention Based Tasks in Adolescents and Young Adults. AB - Objective: Research has demonstrated comorbidity between Attention-Deficit Hyperactivity Disorder (ADHD) and cannabis use, and some have proposed that subclinical ADHD symptoms may explain attentional deficits in cannabis users. Here we investigated whether subclinical ADHD symptoms and cannabis use independently or interactively predict performance on attention tasks in adolescents and young adults. Method: Seventy-two participants (cannabis users (MJ) = 34, Controls = 38) completed neuropsychological tasks of inhibition and attention. Parent report on the Child Behaviors Checklist reflected current ADHD symptoms. Multiple regression analyses examined whether ADHD symptoms and cannabis use independently or interactively predicted cognitive outcomes. Results: Cannabis use was significantly associated with slower CPT hit rate response. Subclinical ADHD symptoms did not independently predict or moderate cannabis effects. Conclusions: Cannabis users demonstrated slower response rate during an attentional task. Subclinical ADHD symptoms did not predict any deficits. As such, attention deficits seen in cannabis users are more related to substance use than ADHD symptomatology. PMID- 30295696 TI - Contributing Towards a Cultural Neuropsychology Assessment Decision-Making Framework: Comparison of WAIS-IV Norms from Colombia, Chile, Mexico, Spain, United States, and Canada. AB - Objective: Test and normative data selection in cross-cultural neuropsychology remain a complex issue. Despite growing awareness, more studies and instruments are needed to adequately address the impact of cultural factors, such as quantity and quality of education. In this study, we examine the interpretive effects of applying six relevant WAIS-IV norms to a Colombian sample. Method: A sample of 305 highly educated Colombian corporate executives completed the WAIS-IV. Data were scored using norms from Colombia, Chile, Mexico, Spain, United States, and Canada and scores were compared using ANOVA. Additionally, a comparative sociodemographic framework was established to contextualize our sample to the standardization samples and populations of the six countries. Results: Colombian and Chilean norms yielded systematically similar FSIQ/Index scores (mean range = 117-121), while incrementally lower scores were found with norms from Mexico (-3 9 points), Spain (-3-11 points), USA (-8-13 points), and Canada (-11-18 points). Verbal scores differed, with highest scores obtained with Mexican and Spanish norms. Working memory and processing speed scores had the lowest score agreement across norms. Conclusions: Although the Chilean norms are more frequently used in Colombia, the recently developed Colombian norms appear optimal for our sample; the scores do not have meaningful differences with those obtained with Chilean norms and offer local population representation fidelity. Mexican, Spanish, US, and Canadian norms underestimated WAIS-IV scores and distorted the sample's score distribution. Finally, verbal scores highlight potential education representation within Spanish and Mexican norms, while working memory and processing speed scores suggest cultural nuances likely captured within different norms. PMID- 30295695 TI - Starting the Fight in the Tumor: Expert Recommendations for the Development of Human Intratumoral Immunotherapy (HIT-IT). AB - A European Society for Medical Oncology (ESMO)-sponsored expert meeting was held in Paris on 08 March 2018 which comprised 11 experts from academia, 11 experts from the pharmaceutical industry and two clinicians who were representatives of ESMO. The focus of the meeting was exclusively on the intratumoral injection/delivery of immunostimulatory agents with the aim of harmonizing the standard terms and methodologies used in the reporting of human intratumoral immunotherapy (HIT-IT) clinical trials to ensure quality assurance and avoid a blurring of the data reported from different studies. The goal was to provide a reference document, endorsed by the panel members, that could provide guidance to clinical investigators, pharmaceutical companies, ethics committees, independent review boards, patient advocates and the regulatory authorities, and promote an increase in the number and quality of HIT-IT clinical trials in the future. Particular emphasis was placed not only on the development of precise definitions to facilitate a better understanding between investigators, but also on the importance of systematic serial biopsies as a driver for translational research and the need for the recording and reporting of data, to facilitate a better understanding of the key processes involved. PMID- 30295697 TI - Strain-GeMS: Optimized subspecies identification from microbiome data based on accurate variant modeling. AB - Motivation: Subspecies identification is one of the most critical issues in microbiome studies, as it is directly related to their functions in response to the environmental stress and their feedbacks. However, identification of subspecies remains a challenge largely due to the small variation between different strains within the same species. Accurate identification of subspecies primarily relies on variant identification and categorization through microbiome data. However current SNP calling and subspecies identification for microbiome data remain underdeveloped. Results: In this work, we have proposed Strain-GeMS for subspecies identification from microbiome data, based on solid statistical model for SNP calling, as well as optimized procedure for subspecies identification. Results on simulated, ab initio and in vivo datasets have shown that Strain-GeMS could always generate more accurate results compared with other subspecies identification methods.

PMID- 30295698 TI - Inferring disease-associated long non-coding RNAs using genome-wide tissue expression profiles. AB - Motivation: Long non-coding RNAs (lncRNAs) are important regulators in wide variety of biological processes, which are linked to many diseases. Compared to protein-coding genes (PCGs), the association between diseases and lncRNAs is still not well studied. Thus, inferring disease-associated lncRNAs on a genome wide scale has become imperative. Results: In this study, we propose a machine learning-based method, DislncRF, which infers disease-associated lncRNAs on a genome-wide scale based on tissue expression profiles. DislncRF uses random forest models trained on expression profiles of known disease-associated PCGs across human tissues to extract general patterns between expression profiles and diseases. These models are then applied to score associations between lncRNAs and diseases. DislncRF was benchmarked against a gold standard data set and compared to other methods. The results show that DislncRF yields promising performance and outperforms the existing methods. The utility of DislncRF is further substantiated on two diseases in which we find that top scoring candidates are supported by literature or independent data sets.

PMID- 30295699 TI - sRNAPrimerDB: Comprehensive primer design and search web service for small non coding RNAs. AB - Motivation: Small non-coding RNAs (ncRNAs), especially microRNAs (miRNAs) and piwi-interacting RNAs (piRNAs), play key roles in many biological processes. However, only a few tools can be used to develop the optimal primer or probe design for the expression profile of small ncRNAs. Here, we developed sRNAPrimerDB, the first automated primer designing and query web service for small ncRNAs. Results: The primer online designing module of sRNAPrimerDB is composed of primer design algorithms and quality evaluation of the polymerase chain reaction (PCR) primer. Five types of primers, namely, generic or specific reverse transcription primers, specific PCR primers pairs, TaqMan probe, double hairpin probe, and hybridization probe for different small ncRNA detection methods, can be designed and searched using this service. The quality of PCR primers is further evaluated using melting temperature, primer dimer, hairpin structure, and specificity. Moreover, the sequence and size of each amplicon are also provided for the subsequent experiment verification. At present, 531,306 and 2,941,669 primer pairs exist across 223 species for miRNAs and piRNAs, respectively, according to sRNAPrimerDB. Several primers designed by sRNAPrimerDB are further successfully validated by subsequent experiments. Availability: sRNAPrimerDB is a valuable platform that can be used to detect small ncRNAs. This module can be publicly accessible at http://www.srnaprimerdb.com or http://123.57.239.141. Supplementary information: Supplementary data are available at Bioinformatics online. PMID- 30295701 TI - Multi-insight visualization of multi-omics data via ensemble dimension reduction and tensor factorization. AB - Motivation: Visualization of high-dimensional data is an important step in exploratory data analysis and knowledge discovery. However, it is challenging, because the interpretation is highly subjective. If we see dimensionality reduction (DR) techniques as the main tool for data visualization, they are like multiple cameras that look into the data from different perspectives or angles. We can hardly prescribe one single perspective for all datasets and problems. One snapshot of data cannot reveal all the relevant aspects of the data in higher dimensions. The reason is that each of these methods has its own specific strategy, normally based on well-established mathematical theories to obtain a low-dimensional projection of the data, which sometimes is totally different from the others. Therefore, relying only on one single projection can be risky, because it can close our eyes to important parts of the full knowledge space. Results: We propose the first framework for multi-insight data visualization of multi-omics data. This approach, contrary to single-insight approaches, is able to uncover the majority of data features through multiple insights. The main idea behind the methodology is to combine several DR methods via tensor factorization and group the solutions into an optimal number of clusters (or insights). The experimental evaluation with low-dimensional synthetic data, simulated multi omics data related to ovarian cancer, as well as real multi-omics data related to breast cancer show the competitive advantage over state-of-the-art methods.

PMID- 30295702 TI - Metwork: a web server for natural products anticipation. AB - Motivation: The annotation of natural products and more generally small molecules is one of the major drawbacks in untargeted mass spectrometry analysis. Molecular networking has emerged as a structured way to organize and mine data from untargeted tandem mass spectrometry (MS/MS) experiments. Despite the great potential of this tool, the annotation is usually performed manually by the expert as only few spectral libraries are available. Results: Herein we propose a web server of in silico metabolization of metabolites that represents a full implementation of the metabolome consistency concept. The workflow is based on MS/MS data, organized in molecular network using the Global Natural Products Social Molecular Networking (GNPS) platform, a collaborative library of reactions and a MS/MS spectra prediction module. Having one node identified in the molecular network, the server generates putative structures and predict the associated MS/MS spectra when the exact mass is detected in the network. A similarity comparison between the MS/MS spectra is then performed in order to annotate the node. Availability: The web server is available at: https://metwork.pharmacie.parisdescartes.fr. PMID- 30295700 TI - Type of infant formula increases early weight gain and impacts energy balance: a randomized controlled trial. AB - Background: Millions of infants are fed breast milk substitutes, and the type of infant formula can impact weight gain patterns. Objective: We conducted a randomized controlled trial to determine the direct impact of 2 types of infant formula (cow milk formula, CMF; extensively protein hydrolyzed formula, EHF) on growth and energy balance. Design: A racially diverse group of formula-fed infants (n = 113) were randomly assigned to either CMF or EHF from the age of 0.75 to 12.5 mo. At each monthly visit, anthropometric measures were obtained to determine growth z scores and weight gain velocity, and to categorize early weight gain patterns as rapid or nonrapid. Also, diet records were collected to determine energy from formula and other sources. Comprehensive assessments of energy balance (intake, expenditure, loss) were made at 0.75, 3.5, and 12.5 mo. Results: Beginning 3 wk after randomization, CMF infants had significantly higher weight, but not length, z scores than did EHF infants, and this persisted after solid foods complemented the formula diet. On average, weight gain velocity from 0.75 to 4.5 mo was within the range of typically growing infants for both groups, yet velocity was 3.9 g/d greater for CMF infants (P = 0.002), who were more likely to be classified as an early rapid weight gainer, than EHF infants (46% compared with 18%; P = 0.007). Early differences in energy intake and fecal loss, yielding greater energy available for deposition among CMF infants, contributed to the differential weight gain patterns. There were no significant differences between the formula treatment groups in total energy expenditure or sleeping energy expenditure. Conclusions: Among healthy infants, the type of formula impacted on early rapid weight gain patterns owing to energy intake and loss mechanisms. Research is needed to identify the macronutrients and other compositional constituents in EHF and breast milk that promote satiation and healthy weight gain during sensitive periods of development. This trial was registered at clinicaltrials.gov as: NCT01700205. PMID- 30295703 TI - DeepHINT: Understanding HIV-1 integration via deep learning with attention. AB - Motivation: Human immunodeficiency virus type 1 (HIV-1) genome integration is closely related to clinical latency and viral rebound. In addition to human DNA sequences that directly interact with the integration machinery, the selection of HIV integration sites has also been shown to depend on the heterogeneous genomic context around a large region, which greatly hinders the prediction and mechanistic studies of HIV integration. Results: We have developed an attention based deep learning framework, named DeepHINT, to simultaneously provide accurate prediction of HIV integration sites and mechanistic explanations of the detected sites. Extensive tests on a high-density HIV integration site dataset showed that DeepHINT can outperform conventional modeling strategies by automatically learning the genomic context of HIV integration from primary DNA sequence alone or together with epigenetic information. Systematic analyses on diverse known factors of HIV integration further validated the biological relevance of the prediction results. More importantly, in-depth analyses of the attention values output by DeepHINT revealed intriguing mechanistic implications in the selection of HIV integration sites, including potential roles of several DNA-binding proteins. These results established DeepHINT as an effective and explainable deep learning framework for the prediction and mechanistic study of HIV integration. Availability: DeepHINT is available as an open-source software and can be downloaded from https://github.com/nonnerdling/DeepHINT.

PMID- 30295705 TI - Hereditary haemorrhagic telangiectasia with multiple complications presenting in an older patient. AB - Hereditary haemorrhagic telangiectasia (HHT) is a rare autosomal dominant multi organ vascular disorder associated with bleeding and a reduced life expectancy. We present a 91-year-old woman with complications of previously undiagnosed HHT. This case demonstrates three potential complications: pulmonary arteriovenous malformation (AVM) resulting in a right to left shunt, cerebral infarctions and pericardial effusion. Despite these potentially life-threatening complications and the reduced life-expectancy associated with HHT the patient has survived to an advanced age. Due to the patient's late diagnosis and frailty, the treatment options of AVM embolization and pericardiocentesis were deemed inappropriate. The patient was treated with tranexamic acid to reduce bleeding severity and discharged home with a care package and home oxygen. PMID- 30295706 TI - Optimal Use Ratio of the Stromal Vascular Fraction (SVF): An Animal Experiment Based on Micro-CT Dynamic Detection After Large-Volume Fat Grafting. AB - Background: The addition of the stromal vascular fraction (SVF) can enhance the postoperative survival rate of fat. However, a universal SVF application method is currently unavailable. Therefore, a simple and convenient guideline for SVF addition is needed for its clinical application. Objectives: To evaluate whether SVF can improve fat survival after large-volume fat grafting, and to find a simple and convenient standard for the clinical use of SVF. Methods: Patient fat samples were obtained after liposuction for SVF preparation and grafting. Four types of grafts were prepared with different SVF ratios: 0:1, 1:1, 2:1 and 4:1 SVF:fat. After intensive mixing, fat grafts (5 ml) were randomly injected into both sides of the backs of athymic rats (n=15). At 24 hours and 1, 3, 6, and 9 months after the operation, microcomputed tomography (micro-CT) scanning was performed to calculate the fat survival rate. Results: Nine months after the operation, the survival rates of fat in the four groups were 8.89 +/- 1.62% (0:1), 18.26 +/- 3.85% (1:1), 8.83 +/- 1.46% (2:1), and 7.96 +/- 1.31% (4:1). The 1:1 group exhibited the greatest survival rate (P <0.01), and the adipose tissue histological patterns and blood vessel quality were enhanced compared with those in the other groups. Conclusions: An appropriate SVF ratio can increase the fat survival rate after large-volume fat grafting, but no linear relationship exists between the SVF ratio and fat survival. The optimal SVF:fat ratio for grafting is 1:1. PMID- 30295707 TI - Tenascin-C Accelerates Adverse Ventricular Remodeling after Myocardial Infarction by Modulating Macrophage Polarization. AB - Aims: Tenascin-C (TN-C) is an extracellular matrix protein undetected in the normal adult heart, but expressed in several heart diseases associated with inflammation. We previously reported that serum TN-C levels of myocardial infarction (MI) patients were elevated during the acute stage, and that patients with high peak TN-C levels were at high risk of left ventricular (LV) remodeling and poor outcome, suggesting that TN-C could play a significant role in the progression of ventricular remodeling. However, the detailed molecular mechanisms associated with this process remain unknown. We aimed to elucidate the role and underlying mechanisms associated with TN-C in adverse remodeling after MI. Methods and Results: MI was induced by permanent ligation of the coronary artery of TN-C knockout (TN-C-KO) and wild-type (WT) mice. In WT mice, TN-C was expressed at the borders between intact and necrotic areas, with a peak at 3-days post-MI and observed in the immediate vicinity of infiltrating macrophages. TN-C KO mice were protected from ventricular adverse remodeling as evidenced by a higher LV ejection fraction as compared with WT mice (19.0+/-6.3% vs. 10.6+/ 4.4%; P < 0.001) at 3 months post-MI. During the acute phase, flow-cytometric analyses showed a decrease in F4/80+CD206lowCD45+ M1 macrophages and an increase in F4/80+CD206highCD45+ M2 macrophages in the TN-C-KO heart. To clarify the role of TN-C on macrophage polarization, we examined the direct effect of TN-C on bone marrow-derived macrophages in culture, observing that TN-C promoted macrophage shifting into an M1 phenotype via Toll-like receptor 4 (TLR4). Under M2-skewing conditions, TN-C suppressed the expression of interferon regulatory factor 4, a key transcription factor that controls M2-macrophage polarization, via TLR4, thereby inhibiting M2 polarization. Conclusions: These results suggested that TN C accelerates LV remodeling after MI, at least in part, by modulating M1/M2 macrophage polarization. PMID- 30295708 TI - The genome of the oyster Saccostrea offers insight into the environmental resilience of bivalves. AB - Oysters are keystone species in estuarine ecosystems and are of substantial economic value to fisheries and aquaculture worldwide. Contending with disease and environmental stress are considerable challenges to oyster culture. Here we report a draft genome of the Sydney Rock Oyster, Saccostrea glomerata, an iconic and commercially important species of edible oyster in Australia known for its enhanced resilience to harsh environmental conditions. This is the second reference genome to be reported from the family Ostreidae enabling a genus-level study of lophotrochozoan genome evolution. Our analysis of the 784-megabase S. glomerata genome shows extensive expansions of gene families associated with immunological non-self-recognition. Transcriptomic analysis revealed highly tissue-specific patterns of expression among these genes, suggesting a complex assortment of immune receptors provide this oyster with a unique capacity to recognize invading microbes. Several gene families involved in stress response are notably expanded in Saccostrea compared with other oysters, and likely key to this species' adaptations for improved survival higher in the intertidal zone. The Sydney Rock Oyster genome provides a valuable resource for future research in molluscan biology, evolution and environmental resilience. Its close relatedness to Crassostrea will further comparative studies, advancing the means for improved oyster agriculture and conservation. PMID- 30295709 TI - Representing Multiple Observed Actions in the Motor System. AB - There is now converging evidence that others' actions are represented in the motor system. However, social cognition requires us to represent not only the actions but also the interactions of others. To do so, it is imperative that the motor system can represent multiple observed actions. The current fMRI study investigated whether this is possible by measuring brain activity from 29 participants while they observed 2 right hands performing sign language gestures. Three key results were obtained. First, brain activity in the premotor and parietal motor cortex was stronger when 2 hands performed 2 different gestures than when 1 hand performed a single gesture. Second, both individual observed gestures could be decoded from brain activity in the same 2 regions. Third, observing 2 different gestures compared with 2 identical gestures activated brain areas related to motor conflict, and this activity was correlated with parietal motor activity. Together, these results show that the motor system is able to represent multiple observed actions, and as such reveal a potential mechanism by which third-party social encounters could be processed in the brain. PMID- 30295710 TI - Diadenosine-Polyphosphate Analogue AppCH2ppA Suppresses Seizures by Enhancing Adenosine Signaling in the Cortex. AB - Epilepsy is a multifactorial disorder associated with neuronal hyperexcitability that affects more than 1% of the human population. It has long been known that adenosine can reduce seizure generation in animal models of epilepsies. However, in addition to various side effects, the instability of adenosine has precluded its use as an anticonvulsant treatment. Here we report that a stable analogue of diadenosine-tetraphosphate: AppCH2ppA effectively suppresses spontaneous epileptiform activity in vitro and in vivo in a Tuberous Sclerosis Complex (TSC) mouse model (Tsc1+/-), and in postsurgery cortical samples from TSC human patients. These effects are mediated by enhanced adenosine signaling in the cortex post local neuronal adenosine release. The released adenosine induces A1 receptor-dependent activation of potassium channels thereby reducing neuronal excitability, temporal summation, and hypersynchronicity. AppCH2ppA does not cause any disturbances of the main vital autonomous functions of Tsc1+/- mice in vivo. Therefore, we propose this compound to be a potent new candidate for adenosine-related treatment strategies to suppress intractable epilepsies. PMID- 30295711 TI - Massive expansion of bitter taste receptors in blind cavefish, Astyanax mexicanus. AB - A sensory deficit both at the individual and the species level can be compensated by increased acuity in other senses. The loss of vision in blind cavefish, Astyanaxmexicanus appears to be partially counterbalanced by enhanced chemosensory perception. Whether such improvement also involves adaptive changes in chemosensory receptor repertoires was unknown. The typical bitter taste receptor repertoire of teleost fishes is reported as three to five genes, much smaller than that of many terrestrial species. Interestingly, several fish species, e.g. mudskipper, have evolved a terrestric life style, but again it was unknown, whether this change in habitat is reflected in the size of gustatory receptor repertoires. We have searched the genomes of fifteen fish species and performed a thorough phylogenetic analysis to delineate their bitter taste receptor repertoires. We report no adaptation for four mudskipper species, which exhibit 3-4 bitter taste receptor genes, and thus a typical teleost repertoire, shaped by few gene losses and minor gene duplications from an ancestral repertoire of four genes. However, and in sharp contrast to all other teleost fish species analysed, blind cavefish possess over twenty intact bitter taste receptors plus several pseudogenes, rivalling the complexity of the human bitter taste receptor repertoire. The gene duplications giving rise to the current cavefish bitter taste receptor repertoire appear to have occurred well before the loss of vision, consistent with this increase in repertoire size constituting a preadaptive trait that conceivably could compensate to some extent for the lack of visual cues. PMID- 30295712 TI - Analysis of Triacylglycerols in Castor Oil Through Liquid Chromatography-Mass Spectrometry Based on Fourier Transform-Ion Cyclotron Resonance-Mass Spectrometry and Gas Chromatography-Mass Spectrometry. AB - Castor oil is a traditional Chinese medicine containing a chemically complex mixture of triacylglycerols (TAGs). Herein, the TAGs in castor oil were analyzed in detail. First, the fatty acid composition of castor oil was examined via methylated derivatisation followed by gas chromatography-mass spectrometry (GC MS). Then, using the fatty acid composition data, liquid chromatography-mass spectrometry (LC-MS) was applied to analyze the composition and relative content of TAGs. Nine TAGs were identified, wherein triricinolein (RRR) constituted ~81% of the total TAG content based on the peak areas. However, the TAGs in castor oil contain hydroxyl groups, which are incompatible with the equivalent carbon number (ECN) rule. Thus, an extended-ECN rule was expressed as E-ECN = CN (carbon number)-2.DB (double-bond number)-6.OH (hydroxyl group number) to characterize the retention of hydroxyl-containing TAGs in HPLC using a C18 column. Moreover, hydroxyl-containing TAGs may become dehydrated when analyzed using atmospheric pressure chemical ionization (APCI), which was confirmed via APCI Fourier transform-ion cyclotron resonance-mass spectrometry (FT-ICR-MS). Thus, the TAGs in castor oil were accurately identified through LC-MS together with FT-ICR-MS and GC-MS. PMID- 30295713 TI - Early Adolescence is a Critical Period for the Maturation of Inhibitory Behavior. AB - Psychiatric conditions marked by impairments in cognitive control often emerge during adolescence, when the prefrontal cortex (PFC) and its inputs undergo structural and functional maturation and are vulnerable to disruption by external events. It is not known, however, whether there exists a specific temporal window within the broad range of adolescence when the development of PFC circuitry and its related behaviors are sensitive to disruption. Here we show, in male mice, that repeated exposure to amphetamine during early adolescence leads to impaired behavioral inhibition, aberrant PFC dopamine connectivity, and reduced PFC dopamine function in adulthood. Remarkably, these deficits are not observed following exposure to the exact same amphetamine regimen at later times. These findings demonstrate that there is a critical period for the disruption of the adolescent maturation of cognitive control and PFC dopamine function and suggest that early adolescence is particularly relevant to the emergence of psychopathology in humans. PMID- 30295714 TI - Yap is Required for Scar Formation but not Myocyte Proliferation During Heart Regeneration in Zebrafish. AB - Aims: The Hippo signaling pathway regulates multiple cellular processes during organ development and maintenance by modulating activity of the transcriptional cofactor Yap. Core components of this pathway are required for neonatal mouse heart regeneration, however, investigations to date have typically focused on expression and activity in cardiomyocytes. Due to the regenerative capacity of zebrafish and the fact that global loss of Yap is not fully embryonic lethal in zebrafish, we leveraged a yap null mutant to investigate the impact of constitutive Yap deletion during zebrafish heart regeneration. Methods and Results: Following cryoinjury in adult hearts, myocyte proliferation was not decreased in yap mutants, contrary to expectations based on mouse data. Experiments in larval zebrafish (Danio rerio) revealed that deletion of either Yap or Taz had a modest effect on heart growth, reducing gross organ size, while their combined deletion was synergistic; thus, Yap and Taz share some overlapping roles in zebrafish heart development. Surprisingly, adult yap mutants exhibited decreased collagen composition at 7 days post injury, suggesting a critical role for Yap in scar formation during heart regeneration. siRNA-mediated Yap knockdown in primary rat (Rattus norvegicus) cardiac cells revealed a fibroblast-specific role for Yap in controlling the expression of cytoskeletal and myofibroblast activation genes, as well as pro-inflammatory cyto/chemokines. Corroborating these RNAseq data, we observed increased macrophage infiltration in the scars of yap mutants at 7 days post injury. Conclusions: These results suggest that Yap deletion has minimal effect on myocyte proliferation in adults, but significantly influences scar formation and immune cell infiltration during zebrafish heart regeneration. Collectively, these data suggest an unexpected role for Yap in matrix formation and macrophage recruitment during heart regeneration. PMID- 30295715 TI - Food impaction: etiology over 35 years and association with eosinophilic esophagitis. AB - With the emergence of eosinophilic esophagitis (EoE) as a common cause of food impaction (FI) and a presumed increase in incidence of EoE in the population, the effect on the incidence of FI has not been well described. The aim of this study is to describe the incidence of FI and endoscopic findings in these patients and the association with EoE. A population-based retrospective chart review of the Rochester Epidemiology Project database was performed to identify all patients within Olmsted County that presented with FI from 1976 to 2012. A review of all endoscopic findings, biopsy results, and demographic data was performed. 497 patients were identified with FI from 1976 to 2012. The overall incidence of FI has changed from 1976 to 2012 (Fig. 1) (P < 0.001). The peak incidence of 17.12 per 100,000 people occurred in the time period 1995 to 2000. Both the incidence of comorbid gastroesophageal reflux disease (GERD) and proton pump inhibitor (PPI) use increased over the time period of the study (P < 0.001 for both). Of these patients, 188 (46.7%) had no abnormalities on their endoscopy. The most common endoscopic finding was stricture in 71 (17.6%) patients followed closely by Schatzki's ring in 68 (16.9%) patients. 139 patients had biopsies performed within 2 years of FI and 50 (36.0%) of those were diagnosed with EoE. We present for the first time the changing incidence of FI over the last 35 years in a population-based setting. We also demonstrate the rise of EoE as an important clinical consideration in patients with FI. PMID- 30295716 TI - High Sensitivity Mapping of Cortical Dopamine D2 Receptor Expressing Neurons. AB - Cortical D2 dopamine receptor (Drd2) have mostly been examined in the context of cognitive function regulation and neurotransmission modulation of medial prefrontal cortex by principal neurons and parvalbumin positive, fast-spiking, interneurons in schizophrenia. Early studies suggested the presence of D2 receptors in several cortical areas, albeit with major technical limitations. We used combinations of transgenic reporter systems, recombinase activated viral vectors, quantitative translatome analysis, and high sensitivity in situ hybridization to identify D2 receptor expressing cells and establish a map of their respective projections. Our results identified previously uncharacterized clusters of D2 expressing neurons in limbic and sensory regions of the adult mouse brain cortex. Characterization of these clusters by translatome analysis and cell type specific labeling revealed highly heterogeneous expression of D2 receptors in principal neurons and various populations of interneurons across cortical areas. Transcript enrichment analysis also demonstrated variable levels of D2 receptor expression and several orphan G-protein-coupled receptors coexpression in different neuronal clusters, thus suggesting strategies for genetic and therapeutic targeting of D2 expressing neurons in specific cortical areas. These results pave the way for a thorough re-examination of cortical D2 receptor functions, which could provide information about neuronal circuits involved in psychotic and mood disorders. PMID- 30295717 TI - Saccadic Adaptation Boosts Ongoing Gamma Activity in a Subsequent Visuoattentional Task. AB - Attention and saccadic adaptation (SA) are critical components of visual perception, the former enhancing sensory processing of selected objects, the latter maintaining the eye movements accuracy toward them. Recent studies propelled the hypothesis of a tight functional coupling between these mechanisms, possibly due to shared neural substrates. Here, we used magnetoencephalography to investigate for the first time the neurophysiological bases of this coupling and of SA per se. We compared visual discrimination performance of 12 healthy subjects before and after SA. Eye movements and magnetic signals were recorded continuously. Analyses focused on gamma band activity (GBA) during the pretarget period of the discrimination and the saccadic tasks. We found that GBA increases after SA. This increase was found in the right hemisphere for both postadaptation saccadic and discrimination tasks. For the latter, GBA also increased in the left hemisphere. We conclude that oculomotor plasticity involves GBA modulation within an extended neural network which persists after SA, suggesting a possible role of gamma oscillations in the coupling between SA and attention. PMID- 30295718 TI - Document triage for identifying protein-protein interactions affected by mutations: a neural network ensemble approach. AB - The precision medicine (PM) initiative promises to identify individualized treatment depending on a patients' genetic profile and their related responses. In order to help health professionals and researchers in the PM endeavor, BioCreative VI organized a PM Track to mine protein-protein interactions (PPI) affected by genetic mutations from the biomedical literature. In this paper, we present a neural network ensemble approach to identify relevant articles describing PPI affected by mutations. In this approach, several neural network models are used for document triage, and the ensemble performs better than any individual model. In the official runs, our best submission achieves an F-score of 69.04% in the BioCreative VI PM document triage task. After post-challenge analysis, to address the problem of the limited size of training set, a PPI pre trained module is incorporated into our approach to further improve the performance. Finally, our best ensemble method achieves an F-score of 71.04% on the test set. PMID- 30295719 TI - Tripal Developer Toolkit. AB - Tripal community database construction toolkit utilizing the content management system Drupal. Tripal is used to make biological, genetic and genomic data more discoverable, shareable, searchable and standardized. As funding for community level genomics databases declines, Tripal's open-source codebase provides a means for sites to be built and maintained with a minimal investment in staff and new development. Tripal is ultimately as strong as the community of sites and developers that use it. We present a set of developer tools that will make building and maintaining Tripal 3 sites easier for new and returning users. These tools break down barriers to entry such as setting up developer and testing environments, acquiring and loading test datasets, working with controlled vocabulary terms and writing new Drupal classes. PMID- 30295720 TI - A survey of ontology learning techniques and applications. AB - Ontologies have gained a lot of popularity and recognition in the semantic web because of their extensive use in Internet-based applications. Ontologies are often considered a fine source of semantics and interoperability in all artificially smart systems. Exponential increase in unstructured data on the web has made automated acquisition of ontology from unstructured text a most prominent research area. Several methodologies exploiting numerous techniques of various fields (machine learning, text mining, knowledge representation and reasoning, information retrieval and natural language processing) are being proposed to bring some level of automation in the process of ontology acquisition from unstructured text. This paper describes the process of ontology learning and further classification of ontology learning techniques into three classes (linguistics, statistical and logical) and discusses many algorithms under each category. This paper also explores ontology evaluation techniques by highlighting their pros and cons. Moreover, it describes the scope and use of ontology learning in several industries. Finally, the paper discusses challenges of ontology learning along with their corresponding future directions. PMID- 30295721 TI - Effect of preoperative inspiratory muscle training on physical functioning following esophagectomy. AB - This study aims to examine the effect of preoperative inspiratory muscle training (IMT) on pre- and postoperative functional exercise performance in patients undergoing esophagectomy. A subcohort of patients recruited to the PREPARE randomized control trial were studied. Following evaluation of respiratory muscle function (spirometry, maximum inspiratory pressure (MIP), and inspiratory muscle endurance), postoperative mobilization (accelerometry) and postoperative physical functioning (6-minute walk test (6MWT)), participants scheduled for esophagectomy were randomly assigned to either 2 weeks of preoperative IMT or a control group. Measures were repeated on the day before surgery and postoperatively. Sixty participants (mean (standard deviation) age 64.13 (7.8) years; n = 42 male; n = 43 transthoracic esophagectomy; n = 17 transhiatial esophagectomy) were included in the final analysis (n = 28 IMT; n = 32 control). There was a significant improvement in preoperative MIP (P = 0.03) and inspiratory muscle endurance (P = 0.04); however preoperative 6MWT distance did not change. Postoperatively, control participants were more active on postoperative day (POD)1, and from POD1 POD5 (P = 0.04). Predischarge, 6MWT distance was significantly lower in the IMT group (305.61 (116.3) m) compared to controls (380.2 (47.1) m, P = 0.03). Despite an increase in preoperative respiratory muscle function, preoperative IMT does not improve pre- or postoperative physical functioning or postoperative mobilization following esophagectomy. PMID- 30295722 TI - Death-Domain-Receptor 3 Deletion Normalizes Inflammatory Gene Expression and Prevents Ileitis in Experimental Crohn's Disease. AB - Background: TNF-like cytokine 1A (TL1A) and its functional receptor, death-domain receptor-3 (DR3), are multifunctional mediators of effector and regulatory immunity. We aimed to evaluate the functional role and therapeutic potential of TL1A/DR3 signaling in Crohn's disease-like ileitis. Methods: Ileitis-prone SAMP1/YitFc (SAMP) and TNFDeltaARE/+ mice were rendered deficient for DR3 or TL1A by microsatellite marker-assisted backcrossing. Pathological and immunological characteristics were compared between control and knockout mice, and mucosal immunophenotype was analyzed by Nanostring microarray assay. The therapeutic effect of pharmacological TL1A neutralization was also investigated. Results: DR3 deficiency was associated with restoration of a homeostatic mucosal immunostat in SAMP mice through the regulation of several pro- and anti-inflammatory genes. This led to suppression of effector immunity, amelioration of ileitis severity, and compromised ability of either unfractionated CD4+ or CD4+CD45RBhi mucosal lymphocytes to transfer ileitis to severe combined immunodeficient mice recipients. TNF-driven ileitis was also prevented in TNFDeltaARE/+xDR3-/- mice, in association with decreased expression of the pro-inflammatory cytokines TNF and IFN-gamma. In contrast to DR3, TL1A was dispensable for the development of ileitis although it affected the kinetics of inflammation, as TNFDeltaARE/+xTL1A /- demonstrated delayed onset of inflammation, whereas administration of a neutralizing, anti-TL1A antibody ameliorated early but not late TNFDeltaARE/+ ileitis. Conclusion: We found a prominent pro-inflammatory role of DR3 in chronic ileitis, which is only partially mediated via interaction with TL1A, raising the possibility for additional DR3 ligands. Death-domain-receptor-3 appears to be a master regulator of mucosal homeostasis and inflammation and may represent a candidate therapeutic target for chronic inflammatory conditions of the bowel. PMID- 30295723 TI - Soil amendment with sewage sludge affects soil prokaryotic community composition, mobilome and resistome. AB - Municipal sewage sludge (MSS) is often directly applied to fields despite concerns regarding the spread of harmful microbes and associated resistance genes (RGs). In this four month microcosm study, the dynamics of prokaryotic communities in agricultural soil and changes in mobile genetic elements and RGs following amendment with stabilized MSS were investigated. TaqMan-based quantitative real-time (q)PCR showed that RG prevalence was high when compared to untreated soil and genes for class 1 integrons (intI1), streptomycin RGs (aadA, strA) and tetracycline RG (tet(W)) were detectable for the duration of the four month study. High-throughput qPCR revealed an enhanced prevalence of aminoglycoside RGs (aacC, aadE), macrolide lincosamide-streptogramin B RGs (ermB, ermF) and tetracycline RGs (tet(L), tet(M), tet(X)). Illumina MiSeq sequencing of 16S rRNA gene fragments amplified from total community DNA revealed significant changes in the prokaryotic community composition both at phylum and genus levels, with lower richness and evenness after MSS amendment followed by gradual recovery after 119 days. Conjugative plasmids captured from MSS using exogenous isolation belonged predominantly to the IncP-1 plasmid group. Our results provide new insights into short- and medium-term effects of MSS amendment on soil prokaryotic communities, including the mobilome and resistome. PMID- 30295724 TI - Extracting chemical-protein relations using attention-based neural networks. AB - Relation extraction is an important task in the field of natural language processing. In this paper, we describe our approach for the BioCreative VI Task 5: text mining chemical-protein interactions. We investigate multiple deep neural network (DNN) models, including convolutional neural networks, recurrent neural networks (RNNs) and attention-based (ATT-) RNNs (ATT-RNNs) to extract chemical protein relations. Our experimental results indicate that ATT-RNN models outperform the same models without using attention and the ATT-gated recurrent unit (ATT-GRU) achieves the best performing micro average F1 score of 0.527 on the test set among the tested DNNs. In addition, the result of word-level attention weights also shows that attention mechanism is effective on selecting the most important trigger words when trained with semantic relation labels without the need of semantic parsing and feature engineering.

AB - Over the past years, herbarium collections worldwide have started to digitize millions of specimens on an industrial scale. Although the imaging costs are steadily falling, capturing the accompanying label information is still predominantly done manually and develops into the principal cost factor. In order to streamline the process of capturing herbarium specimen metadata, we specified a formal extensible workflow integrating a wide range of automated specimen image analysis services. We implemented the workflow on the basis of OpenRefine together with a plugin for handling service calls and responses. The evolving system presently covers the generation of optical character recognition (OCR) from specimen images, the identification of regions of interest in images and the extraction of meaningful information items from OCR. These implementations were developed as part of the Deutsche Forschungsgemeinschaft-funded a standardised and optimised process for data acquisition from digital images of herbarium specimens (StanDAP-Herb) Project. PMID- 30295726 TI - Accurate Detection of Chimeric Contigs via Bionano Optical Maps. AB - Summary: A chimeric contig is contig that has been incorrectly assembled, i.e., a contig that contains one or more mis-joins. The detection of chimeric contigs can be carried out either by aligning assembled contigs to genome-wide maps (e.g., genetic, physical or optical maps) or by mapping sequenced reads to the assembled contigs. Here we introduce a software tool called Chimericognizer that takes advantage of one or more Bionano Genomics optical maps to accurately detect and correct chimeric contigs. Experimental results show that Chimericognizer is very accurate, and significantly better than the chimeric detection method offered by the Bionano Hybrid Scaffold pipeline. Chimericognizer can also detect and correct chimeric optical molecules. Availability: https://github.com/ucrbioinfo/Chimericognizer.

PMID- 30295727 TI - Geotrichum candidum gene expression and metabolite accumulation inside the cells reflect the strain oxidative stress sensitivity and ability to produce flavour compounds. AB - Geotrichum candidum is a fungus-like yeast widely used as a starter culture for cheese ripening for its proteolytic and lipolytic activities and its contribution to the cheese flavours. The sequenced strain G. candidum CLIB 918 was isolated from cheese Pont-L'Eveque. This strain's ability to produce volatile compounds was compared to the ability of a known strong sulphur compound producer G. candidum strain (Gc203). The aminotransferase-coding genes BAT2 and ARO8 were identified to be involved in methionine catabolism. The production of volatile compounds indicated that the sequenced strain was a moderate producer compared to the strong producer strain. The major volatile compounds were produced from sulphur amino acid, branched-chain amino acid and fatty acid metabolisms. Metabolite content of the cells showed that the ability of the strain to produce volatile compounds was inversely proportional to its ability to store amino acids inside the cells. Reduced glutathione, hypotaurine and taurine intracellular concentrations and volatile fatty aldehyde production indicated the role of oxidative stress sensitivity in flavour production. The increase in expression of several genes in a Reblochon-type cheese at the end of ripening confirmed that oxygen and iron were key factors regulating cheese flavour production. PMID- 30295728 TI - DIGREM: an integrated web-based platform for detecting effective multi-drug combinations. AB - Motivation: Synergistic drug combinations are a promising approach to achieve a desirable therapeutic effect in complex diseases through the multi-target mechanism. However, in vivo screening of all possible multi-drug combinations remains cost-prohibitive. An effective and robust computational model to predict drug synergy in silico will greatly facilitate this process. Results: We developed DIGREM (Drug-Induced Genomic Response models for identification of Effective Multi-drug combinations), an online tool kit that can effectively predict drug synergy. DIGREM integrates DIGRE, IUPUI_CCBB, gene set-based and correlation-based models for users to predict synergistic drug combinations with dose response information and drug-treated gene expression profiles.

PMID- 30295729 TI - The Effectiveness of the Positive Mood and Active Life Program on Reducing Depressive Symptoms in Long-term Care Facilities. AB - Background and Objectives: Depression is prevalent among long-term care facility (LTCF) residents. However, interventions are not normally part of the management of these residents due to a shortage of mental health professionals. On the basis of Lewinsohn's behavioral model of depression, we developed a 12-week pleasant activity scheduling intervention, the Positive Mood and Active Life (PMAL) program. This study evaluated the effectiveness of the PMAL program on reducing depressive symptoms and improving quality of life among at-risk LTCF residents. Research Design and Methods: We adopted a cluster randomized controlled trial design. Four LTCFs were randomly assigned as treatment sites and three provided care as usual. At-risk LTCF residents (N = 68) were identified using the Mood Resident Assessment Protocol from the Minimum Data Set 2.0. The PMAL program was delivered to 34 residents. The primary and secondary outcomes were depressive symptoms and quality of life, as measured by the Geriatric Depression Scale-15 (GDS-15) and the World Health Organization Quality of Life scale-BREF (WHOQoL BREF), respectively. Results: After 12 weeks, the GDS-15 score in the intervention group showed a reduction from 7.59 to 5.67, with a significant treatment by time effect (p = .006), based on the mixed model analysis; the WHOQoL-BREF score also substantially increased from 69.83 to 86.61 (p = .000). Discussion and Implications: The PMAL program is effective in reducing depressive symptoms of at-risk LTCF residents. It is a feasible intervention that requires minimum resources and can be integrated with standardized assessment systems.

PMID- 30295731 TI - Mifepristone treatment prior to insertion of a levonorgestrel releasing intrauterine system for improved bleeding control - a randomized controlled trial. AB - STUDY QUESTION: Does pre-treatment with a low dose of mifepristone improve irregular vaginal bleeding patterns during the initial 3 months after LNG-IUS placement? SUMMARY ANSWER: Mifepristone treatment prior to LNG-IUS insertion results in significantly lower bleeding and spotting rates for the first month post insertion but no significant reduction at 3 months post insertion. WHAT IS KNOWN ALREADY: One of the leading causes of premature discontinuation of the LNG IUS is unscheduled bleeding in the first months following its insertion. Up to now, there has been no effective treatment to prevent this side effect which reduces continuation rates for one of the most effective contraceptives. STUDY DESIGN, SIZE, DURATION: This randomized, double blinded, controlled trial was conducted between 2009 and 2015. In total, 68 women opting for a LNG-IUS were screened for eligibility, of whom 58 were randomized at a ratio of 1:1 in blocks of 10 to pre-treatment with mifepristone or a comparator. The main outcome was the rate of bleeding and spotting days reported during the first 3 months post LNG-IUS 52 mg placement. PARTICIPANTS/MATERIALS, SETTING, METHODS: Healthy women with regular and normal menstrual cycles aged 18-43 years were enrolled at a single center in a university hospital; 29 were allocated to 2 months pre treatment with a low dose mifepristone and 29 to the comparator prior to insertion of the LNG-IUS. Women were advised to use barrier methods during the pre-treatment period. Bleeding diaries were collected for the pre-treatment period and for the first 6 months after the LNG-IUS placement. MAIN RESULTS AND THE ROLE OF CHANCE: There were no differences in demographic or baseline characteristics between the study groups. Data for analysis of the main outcome were contributed by a per protocol population of 19 women per group. There was a significant lower bleeding and spotting rate in the mifepristone group (-17.8% points, P < 0.001) after 2 months of pre-treatment and during the first month after the LNG-IUS insertion. In the following months, no significant difference could be seen. While no pregnancies occurred prior to LNG-IUS insertion in the mifepristone group, there were three unintended pregnancies in the comparator group which emphasizes the need for a reliable contraceptive potential in any pre treatment regimen used in clinical practice. LIMITATIONS, REASONS FOR CAUTION: The use of mifepristone prior to the LNG-IUS insertion in this trial was used as prophylaxis against unscheduled bleeding after the placement of the device. Although this side effect constitutes a major concern in a clinical setting, only a subset of women are at risk. This is the first study using pre-treatment to attempt improved bleeding control. The differences were small and the effect was short lasting but the reduced rate of bleeding and spotting observed during the first month following LNG-IUS insertion indicates that this approach may be further explored. The fact that there were three pregnancies in the comparator group stresses the need for any pre-treatment to also protect against unplanned pregnancy. WIDER IMPLICATIONS OF THE FINDINGS: Modified treatment protocols of mifepristone could be used prior to the LNG-IUS insertion to investigate possible further improvement of the outcome. The effect size of the current dose used might have been more prominent in women with LNG-IUS if the treatment also continued some weeks after the placement of the device. Although the low dose of mifepristone used in this trial is not available in Europe, other progesterone receptor modulators currently available could be investigated in larger clinical trials. To avoid unintended pregnancy in the pretreatment period, the dosage used should, ideally, also be effective for contraception and the pretreatment period should be kept as short as possible.

PMID- 30295732 TI - Expression dynamics of the poly-gamma-glutamic acid biosynthesis genes of Bacillus subtilis in response to glucose and glutamic acid-a pilot study. AB - Poly-gamma-glutamic acid (PGA) is biosynthesized by various Bacillus species through PGA synthetase, encoded by the PGA operon comprised of the ywsC and ywtABC genes. Due to the minimal available knowledge, understanding the expression pattern of PGA operon genes is pivotal. In this study, the effect of glucose and glutamic acid on the global gene expression profile of Bacillus subtilis Natto3 was investigated using high throughput microarray, with an emphasis on the PGA operon and genes influencing PGA production. Two treatment groups (set1-in the presence of glutamic acid and set2-in the presence of glutamic acid + glucose) were analyzed against the control (in the presence of glucose). In the microarray, both the groups showed a trend of up-regulation for ywsC and ywtA genes (log2 fold change of 0.55, P = 0.0194, 0.92, P = 0.0069 in set1 and 0.78, P = 0.0023, 0.59, P = 0.0172 in set2, respectively) and down regulation of ywtB and ywtC genes (log2 fold change of -1.83, P = 0.0001, -1.42, P = 0.0017 in set1 and -1.52, P = 0.0012, -0.55, P = 0.1112 in set2, respectively), supporting the indispensability of the ywsC and ywtA genes in PGA production. Interestingly, the ywtB and ywtC genes, belonging to the same operon, were down-regulated in both the conditions (set1 and set2). To the best of our knowledge, this expression pattern of PGA operon genes is a unique observation.

PMID- 30295737 TI - CoMM: a collaborative mixed model to dissecting genetic contributions to complex traits by leveraging regulatory information. AB - Motivation: Genome-wide association studies (GWASs) have been successful in identifying many genetic variants associated with complex traits. However, the mechanistic links between these variants and complex traits remain elusive. A scientific hypothesis is that genetic variants influence complex traits at the organismal level via affecting cellular traits, such as regulating gene expression and altering protein abundance. Although earlier works have already presented some scientific insights about this hypothesis and their findings are very promising, statistical methods that effectively harness multilayered data (e.g., genetic variants, cellular traits and organismal traits) on a large scale for functional and mechanistic exploration are highly demanding. Results: In this study, we propose a collaborative mixed model (CoMM) to investigate the mechanistic role of associated variants in complex traits. The key idea is built upon the emerging scientific evidence that genetic effects at the cellular level are much stronger than those at the organismal level. Briefly, CoMM combines two models: the first model relating gene expression with genotype and the second model relating phenotype with predicted gene expression using the first model. The two models are fitted jointly in CoMM, such that the uncertainty in predicting gene expression has been fully accounted. To demonstrate the advantages of CoMM over existing methods, we conducted extensive simulation studies, and also applied CoMM to analyze 25 traits in NFBC1966 and Genetic Epidemiology Research on Aging (GERA) studies by integrating transcriptome information from the Genetic European in Health and Disease (GEUVADIS) Project. The results indicate that by leveraging regulatory information, CoMM can effectively improve the power of prioritizing risk variants. Regarding the computational efficiency, CoMM can complete the analysis of NFBC1966 data set and GERA data sets in 2 minutes and 18 minutes, respectively.

PMID- 30295736 TI - Endometrial receptivity revisited: endometrial transcriptome adjusted for tissue cellular heterogeneity. AB - STUDY QUESTION: Does cellular composition of the endometrial biopsy affect the gene expression profile of endometrial whole-tissue samples? SUMMARY ANSWER: The differences in epithelial and stromal cell proportions in endometrial biopsies modify the whole-tissue gene expression profiles and affect the results of differential expression analyses. WHAT IS ALREADY KNOWN: Each cell type has its unique gene expression profile. The proportions of epithelial and stromal cells vary in endometrial tissue during the menstrual cycle, along with individual and technical variation due to the method and tools used to obtain the tissue biopsy. STUDY DESIGN, SIZE, DURATION: Using cell-population specific transcriptome data and computational deconvolution approach, we estimated the epithelial and stromal cell proportions in whole-tissue biopsies taken during early secretory and mid secretory phases. The estimated cellular proportions were used as covariates in whole-tissue differential gene expression analysis. Endometrial transcriptomes before and after deconvolution were compared and analysed in biological context. PARTICIPANTS/MATERIAL, SETTING, METHODS: Paired early- and mid-secretory endometrial biopsies were obtained from 35 healthy, regularly cycling, fertile volunteers, aged 23-36 years, and analysed by RNA sequencing. Differential gene expression analysis was performed using two approaches. In one of them, computational deconvolution was applied as an intermediate step to adjust for the proportions of epithelial and stromal cells in the endometrial biopsy. The results were then compared to conventional differential expression analysis. Ten paired endometrial samples were analysed with qPCR to validate the results. MAIN RESULTS AND THE ROLE OF CHANCE: The estimated average proportions of stromal and epithelial cells in early secretory phase were 65% and 35%, and during mid secretory phase, 46% and 54%, respectively, correlating well with the results of histological evaluation (r = 0.88, P = 1.1 * 10-6). Endometrial tissue transcriptomic analysis showed that approximately 26% of transcripts (n = 946) differentially expressed in receptive endometrium in cell-type unadjusted analysis also remain differentially expressed after adjustment for biopsy cellular composition. However, the other 74% (n = 2645) become statistically non significant after adjustment for biopsy cellular composition, underlining the impact of tissue heterogeneity on differential expression analysis. The results suggest new mechanisms involved in endometrial maturation, involving genes like LINC01320, SLC8A1 and GGTA1P, described for the first time in context of endometrial receptivity. LARGE-SCALE DATA: The RNA-seq data presented in this study is deposited in the Gene Expression Omnibus database with accession number GSE98386. LIMITATIONS REASONS FOR CAUTION: Only dominant endometrial cell types were considered in gene expression profile deconvolution; however, other less frequent endometrial cell types also contribute to the whole-tissue gene expression profile. WIDER IMPLICATIONS OF THE FINDINGS: The better understanding of molecular processes during transition from pre-receptive to receptive endometrium serves to improve the effectiveness and personalization of assisted reproduction protocols. Biopsy cellular composition should be taken into account in future endometrial 'omics' studies, where tissue heterogeneity could potentially influence the results.

PMID- 30295739 TI - RAD9A promotes metastatic phenotypes through transcriptional regulation of Anterior Gradient 2 (AGR2). AB - RAD9A plays an important role in prostate tumorigenesis and metastasis related phenotypes. The protein classically functions as part of the RAD9A-HUS1-RAD1 complex but can also act independently. RAD9A can selectively transactivate multiple genes, including CDKN1A and NEIL1 by binding p53-consensus sequences in or near promoters. RAD9A is overexpressed in human prostate cancer specimens and cell lines; its expression correlates with tumor progression. Silencing RAD9A in prostate cancer cells impairs their ability to form tumors in vivo and migrate as well as grow anchorage-independently in vitro. We demonstrate herein that RAD9A transcriptionally controls AGR2, a gene aberrantly overexpressed in patients with metastatic prostate cancer. Transient or stable knockdown of RAD9A in PC-3 cells caused downregulation of AGR2 protein abundance. Reduced AGR2 protein levels were due to lower abundance of AGR2 mRNA. The AGR2 genomic region upstream of the coding initiation site contains several p53 consensus sequences. RAD9A bound specifically to the 5'-untranslated region of AGR2 in PC-3 cells at a partial p53 consensus sequence at position +3136 downstream from the transcription start site, determined by chromatin immunoprecipitation, followed by PCR amplification. Binding of RAD9A to the p53 consensus sequence was sufficient to drive AGR2 gene transcription, shown by a luciferase reporter assay. In contrast, when the RAD9A binding sequence on the AGR2 was mutated, no luciferase activity was detected. Knockdown of RAD9A in PC-3 cells impaired cell migration and anchorage independent growth. However, ectopically expressed AGR2 in RAD9A-depleted PC-3 cells restored these phenotypes. Our results suggest RAD9A drives metastasis by controlling AGR2 abundance.

AB - Objectives: The objective of this study was to characterize the pharmacokinetics of unbound and total concentrations of daptomycin in infected ICU patients with various degrees of renal impairment. From these results, the probability of attaining antimicrobial efficacy and the risks of toxicity were assessed. Methods: Twenty-four ICU patients with various renal functions and requiring treatment of complicated skin and soft-tissue infections, bacteraemia, or endocarditis with daptomycin were recruited. Daptomycin (Cubicin(r)) at 10 mg/kg was administered every 24 h for patients with creatinine clearance (CLCR) >=30 mL/min and every 48 h for patients with CLCR <30 mL/min. Total and unbound plasma concentrations and urine concentrations of daptomycin were analysed simultaneously following a population pharmacokinetic approach. Simulations were conducted to estimate the probability of attaining efficacy (unbound AUCu/MIC >40 or >80) or toxicity (Cmin >24.3 mg/L) targets. Results: Exposure to unbound daptomycin increased when the renal function decreased, thus increasing the probability of reaching the efficacy targets, but also the risk of toxicity. Modifications of the unbound fraction (fu) of daptomycin did not affect the pharmacokinetics of unbound daptomycin, but did affect the pharmacokinetics of total daptomycin. Conclusions: Daptomycin at 10 mg/kg q24h allowed efficacy pharmacokinetic/pharmacodynamic targets for ICU patients with CLCR >=30 mL/min to be reached. For patients with CLCR <30 mL/min, halving the rate of drug administration, i.e. 10 mg/kg q48h, was sufficient to reach these targets. No adverse events were observed, but the toxicity of the 10 mg/kg q24h dosing regimen should be further assessed, particularly for patients with altered renal function.

AB - Endometriosis is a common multifactorial gynecological disorder defined as the proliferation of endometrial tissue outside of the uterine cavity. Neuroangiogenesis (co-recruitment of nerves and blood vessels) is believed to play an integral part in the establishment and growth of endometriotic lesions. We hypothesized that exosomes derived from abnormal endometrium may serve as the second identifier of endometriosis and play an important role in the development of endometriosis by regulating neuroangiogenesis. Primary human endometrial stromal cells (ESCs) were isolated from eutopic endometrium (EmESC, n = 22) with endometriosis and normal endometrium (CoESC, n = 6). Exosomes were isolated from ESCs using "standard" ultracentrifugation method, and the characterization of exosomes were identified through transmission electron microscopy, nanoparticle tracking analysis, and western blot. The role of exosomes in regulating neuroangiogenesis was determined through in vitro tube formation assay, neurite outgrowth assay, and dorsal root ganglion (DRG) neuron apoptosis analysis. The data showed that EmESCs could secrete exosomes with a diameter of approximately 100 nm and a biconcave morphological feature; they were internalized by human umbilical vein endothelial cells (HUVECs) and DRG neurons and enhanced neuroangiogenic effects. We further validated the role of exosomes through blocking experiments. We found that when the exosome secretion was blocked, the pro-neuroangiogenesis effects were decreased. In conclusion, these data suggested that exosomes may play a key role in endometriosis by promoting neuroangiogenesis.

AB - Summary: MicroRNAs (miRNAs) function as master regulators of gene expression. Recent studies demonstrate that miRNA isoforms (isomiRs) play a unique role during cancer development. Here, we present QuagmiR, the first cloud-based tool to analyze isomiRs from next generation sequencing data. Using a novel and flexible searching algorithm designed for the detection and annotation of heterogeneous isomiRs, it permits extensive customization of the query process and reference databases to meet the user's diverse research needs. Availability and implementation: QuagmiR is written in Python and can be obtained freely from GitHub (https://github.com/Gu-Lab-RBL-NCI/QuagmiR). QuagmiR can be run from the command line on local machines, as well as on high-performance servers. A web accessible version of the tool has also been made available for use by academic researchers through the National Cancer Institute-funded Seven Bridges Cancer Genomics Cloud (https://cancergenomicscloud.org). Supplementary information: Supplementary data are available at Bioinformatics online. PMID- 30295745 TI - cath-resolve-hits: a new tool that resolves domain matches suspiciously quickly. AB - Motivation: Many bioinformatics areas require us to assign domain matches onto stretches of a query protein. Starting with a set of candidate matches, we want to identify the optimal subset that has limited/no overlap between matches. This may be further complicated by discontinuous domains in the input data. Existing tools are increasingly facing very large data-sets for which they require prohibitive amounts of CPU-time and memory. Results: We present cath-resolve-hits (CRH), a new tool that uses a dynamic-programming algorithm implemented in open source C ++ to handle large data-sets quickly (up to ~1 million hits/second) and in reasonable amounts of memory. It accepts multiple input formats and provides its output in plain text, JSON or graphical HTML. We describe a benchmark against an existing algorithm, which shows CRH delivers very similar or slightly improved results and very much improved CPU/memory performance on large data-sets. Availability: CRH is available at https://github.com/UCLOrengoGroup/cath-tools; documentation is available at http://cath-tools.readthedocs.io.

PMID- 30295746 TI - Novel high-throughput screening method using quantitative PCR to determine the antimicrobial susceptibility of Orientia tsutsugamushi clinical isolates. AB - Objectives: To develop a method to enable the large-scale antimicrobial susceptibility screening of Orientia tsutsugamushi clinical isolates, using one timepoint and one concentration of antibiotics to considerably speed up the time to result. Methods: Growth, harvesting, multiplicity of infection (moi) and the day to determine the MICs were optimized using five O. tsutsugamushi reference strains [susceptible (Karp, Kato and Gilliam) and putatively resistant (AFC-3 and AFSC-4)], one clinical isolate (UT76) and one rodent isolate (TA763). Subsequently, the MICs of azithromycin, chloramphenicol and doxycycline for these strains and 51 clinical isolates including AFSC-7 were determined. An optimal concentration was calculated using the epidemiological cut-off value. Results: The conditions for O. tsutsugamushi infection, growth and harvesting were determined to be an moi of 100:1 and trypsinization with the peak growth on day 10. The resulting MICs were in line with previously published susceptibility data for all reference strains, except for Karp and AFSC-4, which showed azithromycin MICs of 0.0156 and 0.0313 mg/L, compared with 0.0078 and 0.0156 mg/L, respectively, in previous reports. The MIC of doxycycline for AFC-3 was 0.125 mg/L compared with >4 mg/L in earlier reports. The final single screening concentrations were identified as: azithromycin, 0.125 mg/L; chloramphenicol, 8 mg/L; and doxycycline, 1 mg/L. Conclusions: This simplified procedure facilitates the simultaneous screening of 48 isolates for actively monitoring potential resistance of this important fever pathogen, with an 8-fold throughput improvement over early methods. The data do not support the existence of doxycycline- and chloramphenicol-resistant scrub typhus. PMID- 30295747 TI - Mutual Regulation of TLR/NLR and CEACAM1 in the Intestinal Microvasculature: Implications for IBD Pathogenesis and Therapy. AB - Background: Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) displays multiple activities, among which pathogen binding and angiogenesis are particularly prominent. These same functions are also exerted by Toll- and NOD like receptors (TLRs and NLRs), which are critical mediators of innate immune responses. We investigated whether a functional inter-relationship exists between CEACAM1 and TLRs and NLRs and its potential impact on induction of intestinal angiogenesis. Methods: This hypothesis was tested using human intestinal microvascular endothelial cells, a unique cell population exposed to microbial products under physiological and pathological conditions. Results: The results show that activation of TLR2/4, TLR4, NOD1, and NOD2 by specific bacterial ligands selectively and differentially upregulates the levels of cellular and soluble CEACAM1 produced by intestinal microvascular endothelial cells. The results also show that CEACAM1 regulates the migration, transmigration, and tube formation of these endothelial cells and mediates vessel sprouting induced by specific TLR and NLR bacterial ligands. Combined, these results demonstrate a close and reciprocal regulatory interaction between CEACAM1 and bacterial products in mediating multiple functions essential to new vessel formation in the gut mucosa. Conclusions: A coordinated and reciprocal interaction of CEACAM1 and microbiota-derived factors is necessary to optimize angiogenesis in the gut mucosa. This suggests that a coordination of endogenous and exogenous innate immune responses is necessary to promote intestinal angiogenesis under physiological and inflammatory conditions such as inflammatory bowel disease. PMID- 30295748 TI - Hybrid transgastric approach for the treatment of gastroesophageal junction pathologies. AB - Flexible endoscopy has evolved to the point that it includes many endoluminal procedures that once required open or laparoscopic surgery, for instance, antireflux surgery, pyloromyotomy, mucosal and submucosal tumor resections, and even full-thickness resection. However, these procedures remain technically demanding due to flexible technology issues: difficult imaging, limited energy devices, lack of staplers, unsatisfactory suturing abilities, and so on. Transgastric laparoscopy or hybrid laparoscopy/flex endoscopy has been described for almost two decades as an alternative to a pure endoluminal approach, mainly for pancreatic pseudocyst drainage and full-thickness and mucosal resection of various lesions. The approach has never been widely adopted mostly due to cumbersome and difficult to maintain methods of gastric access. We propose to expand the indications of transgastric laparoscopy by using novel endoscopically placed ports to replicate endoscopic procedures particularly in the difficult to access proximal stomach such as endoluminal antireflux surgery. Under general anesthesia, five female pigs (mean weight: 27.6 kg) had endoscopic placement of 3, 5 mm intragastric ports (Endo-TAGSS, Leakwood KS, USA) using a technique similar to percutaneous endoscopic gastrostomy. A 5-mm laparoscope was used for visualization. Laparoendoscopic-assisted plication of the gastroesophageal junction (GEJ) was performed using 3-0 interrupted sutures (Polysorb(r), Covidien, Mansfield, MA, USA). A functional lumen imagine probe (EndoFLIP(r), Crospon, Inc., Galway, Ireland) was used to measure diameter, cross sectional area (CSA), distensibility, and compliance of GEJ before and after intervention. Once the TAGSS ports were removed, the gastrotomies were closed by using endoscopic over-the-scope clips. At the end of the procedure, animals were euthanized. Five laparoendoscopic-assisted endoluminal plications were performed. The mean operative time was 65.6 min (Endoscopic evaluation: 3.2 min, TAGSS Insertion: 11 min, EndoFLIP evaluation + GEJ Plication: 43.25 min, gastric wall closure: 15 minutes). In all cases, this technique was effective and allowed to achieve an adequate GEJ plication by endoscopic grading and EndoFLIP measurements. Median pre-plication GEJ diameter (D) and median pre-plication GEJ cross-sectional area (CSA) were 11.42 mm (8.6-13.6 mm) and 104.8 mm2 (58-146 mm2). After the procedure, these values were decreased to 6.14 mm (5.7-6.6 mm) and 29.8 mm2 (25-34 mm2) respectively (p = 0.0079). Median pre-plication distensibility (d) and compliance (C) were 7.87 mm2/mmHg (2.4-22.69 mm2/mmHg) and 190.56 mm3/mmHg (70.9-502.8 mm3/mmHg). After the procedure, these values decreased to 1.5 mm2/mmHg (0.7-2.2 mm2/mmHg) and 52.17 mm3/mmHg (21.9-98.7 mm3/mmHg) respectively (p = 0.0317). No intraoperative events were observed. Endoscopically, all valves were felt to be transitioned from a Hill grade 3 (normal state for the animal model) to a Hill grade 1 at the procedure completion. A hybrid laparoendoscopic approach is a feasible alternative for performing intragastric procedures with the assistance of conventional laparoscopic instruments; especially in cases where the intervention location limits the access to standard endoscopy or where endoscopic technology is inadequate. Further evaluation is planned in survival models and clinical trials. PMID- 30295749 TI - A new method bridging graph theory and residue co-evolutionary networks for specificity determinant positions detection. AB - Motivation: computational studies of molecular evolution are usually performed from a multiple alignment of homologous sequences, on which sequences resulting from a common ancestor are aligned so that equivalent residues are placed in the same position. Residues frequency patterns of a full alignment or from a subset of its sequences can be highly useful for suggesting positions under selection. Most methods mapping co-evolving or specificity determinant sites are focused on positions, however, they do not consider the case for residues that are specificity determinants in one subclass, but variable in others. In addition, many methods are impractical for very large alignments, such as those obtained from Pfam, or require a priori information of the subclasses to be analyzed. Results: in this paper we apply the complex networks theory, widely used to analyze co-affiliation systems in the social and ecological contexts, to map groups of functional related residues. This methodology was initially evaluated in simulated environments and then applied to four different protein families datasets, in which several specificity determinant sets and functional motifs were successfully detected. Availability: the algorithms and datasets used in the development of this project are available on http://www.biocomp.icb.ufmg.br/biocomp/software-and-databases/networkstats/.

PMID- 30295750 TI - Estrogen imprinting compromises male sexual behavior and affects the number of androgen receptor-expressing hypothalamic neurons. AB - Neonatal exposure to high dose 17beta-estradiol (E2) affects the morphology and physiology of sex and accessory sex organs in the long term. In this study, we examined the effects of E2 imprinting on male sexual behavior, fertility and the number of androgen receptor (AR) expressing cells in the hypothalamus. E2-treated males showed copulatory behavior represented by mounts and/or intromissions, demonstrating the preservation of aspects of male behavior. They had slightly increased latency for first intromission and a reduced number of ejaculations, associated with a 50% reduction in the fertility index. AR expression in the hypothalamus was assessed by RT-PCR, Western blotting and immunohistochemistry. Treated rats had a significantly lower ventral prostate weight, demonstrating the efficacy of the treatment. The AR mRNA and protein content in the hypothalamus of E2-treated animals was reduced to the levels of females. AR-expressing cell counts in the ventromedial, anterior medial preoptic, paraventricular nuclei and preoptic area were different from control males, and similar to those of females. In conclusion, E2 imprinting resulted not only in ill-developed sexual organs, but also affected sexual behavior, resulting in a female-type hypothalamus, at least with respect to the abundance of AR mRNA and protein and the number of AR expressing cells in important regions/tracts. PMID- 30295751 TI - Infections of the esophagus: an update on risk factors, diagnosis, and management. AB - Infectious esophagitis is a leading cause of esophagitis worldwide. While esophageal infections have traditionally been associated with immunocompromised patients, these disorders are becoming increasingly recognized in immunocompetent individuals. The three most common etiologies of infectious esophagitis are Candida, herpes simplex virus, and cytomegalovirus. Human papilloma virus infection can also involve the esophagus in the form of ulcerative lesions and papillomas. Less common etiologies include various other fungal, bacterial, and viral organisms. This review provides a comprehensive update on risk factors, diagnosis, and management of both common and less common infections of the esophagus. PMID- 30295752 TI - Texture analysis of computed tomography data using morphologic and metabolic delineation of esophageal cancer-relation to tumor type and neoadjuvant therapy response. AB - The prognostic values of image-based tumor texture analysis based on computed tomography (CT) and of limiting the segmented tumor volume to metabolically active regions using fludeoxyglucose-positron emission tomography (FDG-PET) were studied in 25 patients with esophageal adenocarcinoma and 11 patients with squamous cell carcinoma. The aims of this study are to describe their CT-image based texture characteristics before and after neoadjuvant therapy and to evaluate whether limiting the examined tumor volume to metabolically active regions detected with FDG-PET image data would further improve their value. Textural parameters (homogeneity, energy, entropy, contrast, and correlation) based on gray-level co-occurrence matrices (GLCM) were calculated for 3D volumes of segmented esophageal tumors before and after neoadjuvant chemotherapy or radiochemotherapy. Histopathological data after surgical resection and textural parameters before and after neoadjuvant treatment were compared using the Mann Whitney U test. Significant differences in the textural parameters were observed between adenocarcinoma and squamous cell carcinoma for homogeneity, energy, inertia, and correlation. The use of contrast media during scanning resulted in significant differences in homogeneity, energy, entropy, and inertia for adenocarcinoma but not squamous cell carcinoma. There was also a significant difference in all textural parameters between pathological T status for ypT0-ypT2 and ypT3-ypT4 adenocarcinomas, but not in squamous cell carcinoma patients. No additional value was found from using PET image data to aid segmentation of CT images. PMID- 30295753 TI - Murine PAIP1 stimulates translation of spermiogenic mRNAs stored by YBX2 via its interaction with YBX2. AB - The expression of many genes during the post-meiotic stages of spermatogenesis is largely regulated by germ cell-specific RNA binding proteins at the level of post transcription. One of these RNA binding proteins, YBX2, participates in mRNA storage and regulation of translation in haploid spermatids. How YBX2-stored mRNAs become translationally competent during spermiogenesis remains unknown. In the present study, we report for the first time that YBX2 interacts with PAIP1, a protein translation enhancer, in vitro and in vivo. In murine testes, PAIP1 is highly expressed and co-localizes with YBX2 in round spermatids. Using sequential RNA immunoprecipitation and sequence analysis, we identified a group of spermiogenic mRNAs indirectly bound by PAIP1 through YBX2. Translation of mRNAs bearing the YBX2 target sequence was significantly blocked by YBX2 protein, but was re-initiated when YBX2 was co-expressed with PAIP1 in vitro. Taken together, these results indicate that PAIP1 regulates the translation of YBX2-masked mRNAs during spermiogenesis, and we propose this YBX2-PAIP1 interaction plays an important role in male germ cell development. PMID- 30295754 TI - WGS analysis of a penicillin-resistant Neisseria meningitidis strain containing a chromosomal ROB-1 beta-lactamase gene. AB - Objectives: Neisseria meningitidis is rarely penicillin resistant. We describe WGS analysis of a penicillin-resistant N. meningitidis collected from a case of invasive meningococcal disease. Methods: Serogrouping, serotyping and serosubtyping were performed with specific antibodies. beta-Lactamase was detected by nitrocefin. MICs were determined by Etest and agar dilution. Sequencing of N. meningitidis genomes was done on the Illumina MiSeq platform and genome data were analysed using the Bacterial Isolate Genome Sequence Database (BIGSdb) on the PubMLST Neisseria website (https://pubmlst.org/neisseria/). Transformation was used to confirm the genetic basis of the penicillin resistance. Results: An N. meningitidis blood isolate from a female patient in her mid-50s with a painful and septic left shoulder was found to have penicillin MIC values of 3-12 mg/L. The isolate was typed as Y: 14, 19: P1.- and ST3587, and was weakly beta-lactamase positive. WGS analysis identified a full-length copy of the beta-lactamase gene blaROB-1, which was contained on a 1719 bp insert with a G + C content of 41.7% (versus a G + C content of N. meningitidis of 51.7%), suggesting that the blaROB-1 gene came from a different bacterial species. A GenBank analysis of the blaROB-1 gene insert found 99.77% identity with a DNA segment found in plasmid pB1000' from Haemophilus influenzae. Transformation of a penicillin-susceptible strain with the blaROB-1 gene conferred beta-lactamase activity and penicillin resistance. Conclusions: N. meningitidis serogroup Y, ST3587 can carry and express the blaROB-1 gene, leading to penicillin resistance. It is highly likely that the N. meningitidis isolate acquired the blaROB-1 gene from H. influenzae.

PMID- 30295756 TI - Single dose of empagliflozin increases in vivo cardiac energy status in diabetic db/db mice. PMID- 30295757 TI - Contraceptive drugs mitigate experimental stroke-induced brain injury. AB - Aims: Effective stroke treatments beyond reperfusion remain scant. The natural steroid hormone progesterone has shown protective effects in experimental models of brain injury and cardiovascular disease. However, unfavorable bioavailability limits its clinical use. Desogestrel and drospirenone are new generation progestins with progesterone-like properties, developed as oral contraceptives with excellent bioavailability and safety profile. We investigated the neuroprotective properties of these progestins in vivo using transient middle cerebral artery occlusion (MCAO) and in vitro using an oxygen-glucose deprivation and reoxygenation (OGD/R) model in primary neuronal cells. Methods and Results: MCAO was induced in female, female ovariectomized (modeling postmenopausal females) and male mice. Treatment with the progestins resulted in less severe strokes after MCAO and less neuronal death in OGD/R. Desogestrel and drospirenone induced higher expression levels of GABAAR alpha4 and delta subunits within the brain, suggesting changes in GABAAR configuration favoring tonic inhibition as potential mechanism of action. Treatment with the GABAAR blocker picrotoxin abolished the protection afforded by the progestins in vivo and in vitro. Conclusions: For the first time, here we delineate a potential role of desogestrel and drospirenone, both clinically approved and safe drugs in mitigating the consequences of stroke. Contraception with desogestrel and drospirenone in progestin-only preparations may be particularly beneficial for women at risk of stroke. PMID- 30295758 TI - 2-arachidonoylglycerol mobilizes myeloid cells and worsens heart function after acute myocardial infarction. AB - Aims: Myocardial infarction leads to an enhanced release of endocannabinoids and a massive accumulation of neutrophils and monocytes within the ischemic myocardium. These myeloid cells originate from hematopoietic precursors in the bone marrow and are rapidly mobilized in response to myocardial infarction. We aimed to determine whether endocannabinoid signaling is involved in myeloid cell mobilization and cardiac recruitment after ischemia onset. Methods and results: Intravenous administration of endocannabinoid 2-arachidonoylglycerol into wildtype C57BL6 mice induced a rapid increase of blood neutrophil and monocyte counts as measured by flow cytometry. This effect was blunted when using cannabinoid receptor 2 knockout mice. In response to myocardial infarction induced in wildtype mice, the lipidomic analysis revealed significantly elevated plasma and cardiac levels of the endocannabinoid 2-arachidonoylglycerol 24 h after infarction, but no changes in anandamide, palmitoylethanolamide and oleoylethanolamide. This was a consequence of an increased expression of 2 arachidonoylglycerol synthesizing enzyme diacylglycerol lipase and a decrease of metabolizing enzyme monoacylglycerol lipase in infarcted hearts, as determined by quantitative RT-PCR analysis. The opposite mRNA expression pattern was observed in bone marrow. Pharmacological blockade of monoacylglycerol lipase with JZL184 and thus increased systemic 2-arachidonoylglycerol levels in wildtype mice subjected to myocardial infarction resulted in elevated cardiac CXCL1, CXCL2 and MMP9 protein levels as well as higher cardiac neutrophil and monocyte counts 24 h after infarction compared to vehicle-treated mice. Increased post-myocardial infarction inflammation in these mice led to an increased infarct size, an impaired ventricular scar formation assessed by histology and a worsened cardiac function in echocardiography evaluations up to 21 days. Likewise, JZL184 administration in a myocardial ischemia-reperfusion model increased cardiac myeloid cell recruitment and resulted in a larger fibrotic scar size. Conclusions: These findings suggest that changes in endocannabinoid gradients due to altered tissue levels contribute to myeloid cell recruitment from the bone marrow to the infarcted heart, with crucial consequences on cardiac healing and function.

PMID- 30295760 TI - Cost-effectiveness of 3 months of weekly rifapentine and isoniazid compared with other standard treatment regimens for latent tuberculosis infection: a decision analysis study. AB - Background: Latent tuberculosis infection (LTBI) is a critical driver of the global burden of active TB, and therefore LTBI treatment is key for TB elimination. Treatment regimens for LTBI include self-administered daily isoniazid for 6 (6H) or 9 (9H) months, self-administered daily rifampicin plus isoniazid for 3 months (3RH), self-administered daily rifampicin for 4 months (4R) and weekly rifapentine plus isoniazid for 3 months self-administered (3HP SAT) or administered by a healthcare worker as directly observed therapy (3HP DOT). Data on the relative cost-effectiveness of these regimens are needed to assist policymakers and clinicians in selecting an LTBI regimen. Objectives: To evaluate the cost-effectiveness of all regimens for treating LTBI. Methods: We developed a Markov model to investigate the cost-effectiveness of 3HP-DOT, 3HP SAT, 4R, 3RH, 9H and 6H for LTBI treatment in a cohort of 10 000 adults with LTBI. Cost-effectiveness was evaluated from a health system perspective over a 20 year time horizon. Results: Compared with no preventive treatment, 3HP-DOT, 3HP SAT, 4R, 3RH, 9H and 6H prevented 496, 470, 442, 418, 370 and 276 additional cases of active TB per 10 000 patients, respectively. All regimens reduced costs and increased QALYs compared with no preventive treatment. 3HP was more cost effective under DOT than under SAT at a cost of US$27 948 per QALY gained. Conclusions: Three months of weekly rifapentine plus isoniazid is more cost effective than other regimens. Greater recognition of the benefits of short course regimens can contribute to the scale-up of prevention and achieving the 'End TB' targets.

AB - Objective: Quantify physiologically acceptable PICU-discharge vital signs and develop machine learning models to predict these values for individual patients throughout their PICU episode. Methods: EMR data from 7256 survivor PICU episodes (5632 patients) collected between 2009 and 2017 at Children's Hospital Los Angeles was analyzed. Each episode contained 375 variables representing physiology, labs, interventions, and drugs. Between medical and physical discharge, when clinicians determined the patient was ready for ICU discharge, they were assumed to be in a physiologically acceptable state space (PASS) for discharge. Each patient's heart rate, systolic blood pressure, diastolic blood pressure in the PASS window were measured and compared to age-normal values, regression-quantified PASS predictions, and recurrent neural network (RNN) PASS predictions made 12 hours after PICU admission. Results: Mean absolute errors (MAEs) between individual PASS values and age-normal values (HR: 21.0 bpm; SBP: 10.8 mm Hg; DBP: 10.6 mm Hg) were greater (p < .05) than regression prediction MAEs (HR: 15.4 bpm; SBP: 9.9 mm Hg; DBP: 8.6 mm Hg). The RNN models best approximated individual PASS values (HR: 12.3 bpm; SBP: 7.6 mm Hg; DBP: 7.0 mm Hg). Conclusions: The RNN model predictions better approximate patient-specific PASS values than regression and age-normal values. PMID- 30295769 TI - Trends in antifungal use in US hospitals, 2006-12. AB - Background: Although trends in antibiotic use have been characterized, less is known about antifungal use. Data on antifungal use are important for understanding practice patterns, assessing emergence of antifungal resistance and developing antifungal stewardship programmes. We estimated national trends in inpatient antifungal use in the USA. Methods: Using billing data for antifungals from the Truven Health MarketScan(r) Hospital Drug Database during 2006-12, we estimated the proportion of discharges at which antifungals were given and days of therapy (DOT)/1000 patient days (PDs) by antifungal drug type, year, patient and facility characteristics. We created national estimates using weights generated from Centers for Medicare and Medicaid Services data and assessed trends over time. Results: Overall, 2.7% of all inpatients and 7.7% of those in ICUs received antifungals. The estimated DOT/1000 PDs for any antifungal was 35.0 for all inpatients and 73.7 for ICU patients. Azoles accounted for 80% of all antifungal use (28.5/1000 PDs), followed by echinocandins (5.0/1000 PDs). By multivariable trend analysis, DOT/1000 PDs for azoles (-21%) and polyenes (-47%) decreased between 2006 and 2012, whereas echinocandins increased 11% during 2006 10 and declined after 2011. Unspecified septicaemia, HIV and antineoplastic therapy were among the top primary diagnosis codes for patients who received antifungals. Conclusions: Antifungals were most frequently used in ICU settings and fluconazole accounted for a large, but declining, proportion of antifungal use. Antifungal stewardship efforts may have the most impact if focused in ICUs, among certain patient groups (e.g. HIV and malignancy) and on stopping empirical antifungal therapy for unspecified sepsis when not indicated. PMID- 30295771 TI - Antimicrobial resistance and virulence factors of Klebsiella pneumoniae affecting 30 day mortality in patients with bloodstream infection. AB - Objectives: To investigate the risk factors of patients with Klebsiella pneumoniae (KP) bloodstream infection (BSI) with a focus on antimicrobial resistance and virulence factors. Methods: All KP BSI patients (n = 579) from six general hospitals during a 1 year period were included in this study. The risk factors of hosts and causative KP isolates were assessed to determine associations with the 30 day mortality of KP BSI patients by multivariate Cox hazards modelling. Results: The 30 day mortality rate of KP BSI patients was 16.9% (98/579). Among the host-associated factors, increased SOFA score and leucopenia status exhibited strong associations with increased 30 day mortality. Among the pathogenic factors, carriage of the pks gene cluster (adjusted HR 1.80; 95% CI 1.16-2.79) was a risk factor, especially when accompanied by MDR. In this regard, KP isolates of the wzi50 capsular type (n = 22) frequently harboured pks (63.6%, 14/22) and ybtA (68.2%, n = 15) and mostly exhibited MDR (63.6%, n = 14), resulting in increased 30 day mortality. In contrast, hypermucoviscous KP isolates showed an inverse association with 30 day mortality (adjusted HR 0.55; 95% CI 0.33-0.90). Conclusions: Despite the reported virulence of hypermucoviscous KP strains, they were associated with good prognoses in KP BSI patients. Importantly, carriage of the pks gene cluster, which is responsible for the synthesis of colibactin, was a relevant marker of early mortality. PMID- 30295772 TI - Intraoperative computed tomography-guided pulmonary tumour localization: a thoracic surgeon's learning curve. AB - OBJECTIVES: With the increasing availability of hybrid operating rooms, single stage tumour localization and removal under intraoperative computed tomography (CT) guidance is gaining popularity. The objective of this study was to describe the learning curve for this procedure. METHODS: Over a 15-month period, a single team of thoracic surgeons without experience in intraoperative CT-guided lung tumour localization performed a total of 91 procedures in 89 patients. All these procedures were conducted in a hybrid operating room equipped with cone-beam CT and a laser navigation system. The learning curve was analysed using the cumulative sum method (target success rate 90%), whereas the moving average was used as an indicator of localization time. RESULTS: The mean lung tumour size on preoperative CT images was 7.81 mm, whereas their mean distance from the pleural surface was 10.16 mm. The localization time (mean 21.19 min) was inversely associated with the surgeon's experience (Pearson's r = -0.6601; P < 0.001). The moving average analysis revealed that localization time stabilized after 32 procedures. There were 6 failures; of these, 2 occurred during lesion localization (as a result of needle puncture-related pneumothorax) and 4 during surgery (caused either by wire dislodgement or dye spillage). The cumulative sum analysis revealed that proficiency was achieved after 38 procedures. The mean localization time and success rates before and after procedure 38 were 32.13 min vs 13.34 min (P < 0.001) and 86.8% vs 98.1% (P = 0.078), respectively. CONCLUSIONS: The procedural time and success rates of intraoperative CT-guided lung tumour localization were optimized after 38 consecutive procedures.

PMID- 30295776 TI - Larviciding Culex spp. (Diptera: Culicidae) Populations in Catch Basins and Its Impact on West Nile Virus Transmission in Urban Parks in Atlanta, GA. AB - In urban environments, road-side catch basins are common larval habitats of Culex spp. (Diptera: Culicidae) mosquitoes and important targets of larval control in areas subject to West Nile virus (WNv) transmission. We quantified the impact of larviciding basins on Culex spp. populations and WNv infection prevalence by treating basins in and around urban parks in Atlanta, GA, using Mosquito Dunks and Bits (active ingredient, a.i., Bacillus thuringiensis subsp. isrealensis, Dunks-10.31%, Bits-2.86%) and Altosid 30-Day Briquets (a.i., S-methoprene 8.62%) in two separate seasons. Treatments were coupled with WNv surveillance using gravid traps and aspiration of adults resting in basins. Larviciding led to >90% reductions in Culex spp. larval and pupal collections (Dunks/Bits) and >90% pupal mortality (Briquets) in treated sites during treatment periods; however, we did not observe significant reductions in Culex spp. collections in gravid traps (general linear mixed-effects model [GLMM] result, P > 0.1) or in adults collected resting in basins (GLMM, P > 0.5). In addition, WNv infection prevalence in Culex spp. mosquitoes was similar between treated and untreated sites (GLMM, P > 0.05). Larval control remains important for controlling WNv in Atlanta; however, at the scale and frequency applied in our study, larval control alone may not lead to meaningful reductions in adult populations and WNv infection prevalence. A greater understanding of the annual dynamics of Culex spp. breeding and the importance of basins as Culex spp. larval habitats are needed to meaningfully affect WNv in cities such as Atlanta. PMID- 30295777 TI - Sellar Region Atypical Teratoid/Rhabdoid Tumors in Adults: Clinicopathological Characterization of Five Cases and Review of the Literature. AB - Atypical teratoid/rhabdoid tumors (AT/RTs) are highly malignant CNS neoplasms that typically occur in children <2 years of age. These are characterized by high grade histologic features and mutations of the INI1/SMARCB1 gene readily detected by loss of expression by immunohistochemistry. Among adults, the majority of AT/RTs occurs in the cerebral hemispheres. A small number of adult AT/RTs involving the sellar and suprasellar region reported in the literature suggest a distinct clinical course for this group. Here, we describe detailed clinical and genetic characterization of 5 adult patients with AT/RTs involving the sellar and suprasellar region, and provide a review of the available clinical and genetic features of 22 previously reported cases in order to help increase our understanding of this unusual entity. PMID- 30295778 TI - The retrospective study of 93 patients with transmigration of mandibular canine and a comparative analysis with a control group. AB - Objectives: The aim of this study was to evaluate characteristics of patients with unilateral transmigration of a mandibular canine in the largest study group presented until now. Materials and methods: The study group consisted of 93 patients with unilateral transmigration of mandibular canine; the control group included 85 non-affected patients. Type of transmigration, status of deciduous and permanent canines, prevalence of missing teeth, class of occlusion, and space conditions were assessed to draw comparisons between groups. Results: In this study, 64.5 per cent patients presented type 1 of transmigration; types 2, 3, 4, and 5 were present in, respectively, 23.7, 5.4, 4.3, and 2.1 per cent patients. There was a clear, statistically significant difference (P < 0.0001) between the mean crown and apex migration and angulation for the three groups of canines (transmigrated, contralateral, and control), whereas no differences were observed for the total number of permanent teeth present. In the study group, 73.1 per cent patients retained their primary canine on the affected side and 18.3 per cent on the contralateral side; in the control group, 22.3 per cent subjects had at least one primary canine. There was a statistically significant difference in the distribution of types of malocclusion between the study and the control groups. Conclusions: Transmigration of mandibular canine was associated with the presence of retained primary canine on the affected side, higher mesial tilting of contralateral mandibular canine when compared to the canines in the control group. Additionally, higher prevalence of Angle's Class I occlusion in patients with canine transmigration was recorded. PMID- 30295779 TI - Colitis alters oxysterol metabolism and is affected by 4beta-hydroxycholesterol administration. AB - Background and aims: Inflammatory bowel diseases (IBD) represent a challenging health issue with a complex etiology implicating genetic and environmental parameters. Although the understanding of their pathophysiology has improved, much remains to be explored. In this context, bioactive lipids, more specifically oxysterols, i.e. oxygenated derivatives of cholesterol, represent an interesting avenue to investigate. Indeed, oxysterols or their receptors are involved in inflammation and immune regulation. Therefore, we set out to study the oxysterome in IBD. Methods: We used both HPLC-MS and molecular biology tools to quantify oxysterol levels and the expression of their metabolic enzymes in several models of murine colitis (both acute and chronic), as well as in colon biopsies from patients with Crohn's disease and ulcerative colitis. Results: We found that the oxysterome is altered in IBD, both in acute and chronic murine models as well as in human IBD. Two of the oxysterols quantified, 4beta-hydroxycholesterol and 25 hydroxycholesterol, were consistently altered in all of our models and therefore could be of interest in this context. Hence, we administered them to mice with colitis. While 25-hydroxycholesterol had no effect, 4beta-hydroxycholesterol worsened colon inflammation. Conclusions: Our study addresses the potential involvement of oxysterols in colitis and clearly points towards an active role as well as a clinical relevance for these bioactive lipids. PMID- 30295780 TI - Empirical treatment of urinary tract infections: how rational are our guidelines? AB - Objectives: This study considers susceptibility test results obtained over a 6 month period for Enterobacteriaceae that caused urinary tract infections (UTIs) in the Cork region of Ireland and uses these results to examine the suitability of Irish empirical treatment guidelines. Patients and methods: UTI-causing Enterobacteriaceae isolates were analysed using EUCAST guidelines to determine resistance to a set of commonly prescribed antimicrobial agents, i.e. ampicillin, amoxicillin/clavulanate, cefalexin, ciprofloxacin, nitrofurantoin and trimethoprim. Patients were categorized by age and patient type, based on origin (hospital inpatients, patients in long-term care facilities and all other non hospitalized patients). In total, 8999 test results were analysed using the IBM Cognos Analytics Series 7 interrogation tool and Microsoft Office Excel. Results: A variety of resistance patterns were observed. Only one antimicrobial agent, nitrofurantoin, demonstrated a resistance rate of less than 20% for all patient categories considered. Conclusions: Previous studies determined that a resistance rate of >20% renders an antimicrobial agent unsuitable for use as an empirical treatment option. This study demonstrated that this resistance rate is exceeded in many cases, potentially rendering some antimicrobial agents unsuitable for use as empirical treatment. We suggest that the focus on susceptibility when producing surveillance data to create empirical treatment guidelines may inadvertently camouflage resistance rates. The findings of this study highlight the need for laboratory-guided treatment of UTIs and ideally a pre-emptive sample should be obtained for laboratory investigation prior to commencement of antimicrobial therapy. PMID- 30295781 TI - Biomarkers Are Associated With Clinical and Endoscopic Outcomes With Vedolizumab Treatment in Ulcerative Colitis. AB - Background: Vedolizumab inhibits alpha4beta7-mediated lymphocyte trafficking and is effective in ulcerative colitis (UC). This study evaluated drug and biomarker concentrations and patient outcomes during vedolizumab treatment in UC. Methods: Prospectively scored maintenance clinical (26.5 weeks; interquartile range [IQR], 16.3-37.0 weeks) and endoscopic (23.5 weeks; IQR, 16.8-35.6 weeks) outcomes were compared with serum vedolizumab concentrations, antivedolizumab antibodies, and serum biomarkers at baseline and weeks 2, 6, 14, and 26. A linear mixed-effects model compared biomarker trajectories over time between clinical and endoscopic remitters and nonremitters. Results: Thirty-two patients were included. Soluble (s)-tumor necrosis factor (TNF)-alpha, s-alpha4beta7, s-mucosal addressin cell adhesion molecule (s-MAdCAM-1), and s-amyloid A (s-AA) significantly changed with treatment. A linear mixed-effects model demonstrated that s-alpha4beta7 (P = 0.044) increased and s-MAdCAM-1 (P = 0.006) and s-vascular cell adhesion molecule 1 (s-VCAM-1, P = 0.001) decreased more rapidly in patients achieving clinical remission in maintenance. S-MAdCAM-1 (P = 0.005), s-intracellular adhesion molecule-1 (ICAM-1; P = 0.014), s-VCAM-1 (P < 0.001), and s-TNF (P = 0.052) decreased more rapidly in endoscopic remitters. In clinical remitters, higher week 14 (20.3 ng/mL vs 6.0 ng/mL; P = 0.013) and week 26 (14.1 ng/mL vs 8.6 ng/mL; P = 0.05) s-alpha4beta7 were observed. In endoscopic remitters, week 2 (6.7 pg/mL vs 17.8 pg/mL; P = 0.038) and week 6 (3.9 pg/mL vs 15.6 pg/mL; P = 0.005) s-TNF and week 14 s-VCAM (589.1 ng/mL vs 746.0 ng/mL; P = 0.05) were lower. Conclusion: Serum biomarkers were associated with outcomes in vedolizumab treated UC patients. s-alpha4beta7 increased, whereas s-MAdCAM-1, s-VCAM-1, s ICAM-1, and s-TNF decreased more rapidly in remitters. At individual time points, induction s-TNF and maintenance s-VCAM-1 concentrations were lower, whereas maintenance s-alpha4beta7 concentrations were higher in remitters. PMID- 30295782 TI - Effect of Temperature on Oviposition Behavior and Egg Load of Blow Flies (Diptera: Calliphoridae). AB - Making optimal oviposition decisions is especially important for female carrion colonizing insects whose larvae often depend on ephemeral resources. Optimal oviposition theory predicts that females should exhibit behaviors that will maximize the performance of their offspring. Oviposition can be influenced by a variety of factors, including temperature. The aim of this study was to investigate the effects of temperature on the oviposition behavior and egg load of two blow fly species native to southern Ontario: Phormia regina Meigen, and Lucilia sericata Meigen (Diptera: Calliphoridae). Using fetal pig carcasses as an oviposition substrate, we assessed the length of time until the first oviposition event, preferred oviposition sites, and the total number of eggs oviposited. For each of the two species, five different temperature treatments ranging from 15 to 35 degrees C were used. Temperature influenced time to the first oviposition event, as well as the number of eggs deposited by L. sericata and P. regina. As temperature increased, oviposition occurred faster with more eggs deposited for these two species. Female P. regina, in particular, demonstrated a higher egg load with increasing temperature. Differences in optimal temperatures for reproduction, including egg load and oviposition, may be a mechanism driving seasonal temporal resource partitioning leading to species coexistence utilizing ephemeral resources. PMID- 30295783 TI - Impact of socioeconomic status on incident heart failure and left ventricular dysfunction: Systematic review and meta-analysis. AB - Aims: Socioeconomic status (SES) is recognizably linked with incident heart failure (HF) risk and the association of SES with geography presents a potential target for geographical location of preventive health services. To better inform policy we sought to quantify the independent association between SES and incident HF and investigate differences by type of SES measure. Methods and results: MEDLINE and EMBASE were searched up to August 2018. Observational studies and randomized trials reporting adjusted HF incidence by stratified socioeconomic measures were included. Effect sizes reflected HF incidence in the lowest versus highest SES stratum and were pooled using a random-effects model. Low SES referred to the lowest resource stratum, the definition of which varied across studies: meta-analysis was only performed where strata were comparable. Statistical heterogeneity was assessed using the I2 statistic. Eleven studies comprising 6,308,006 individuals and 104,217 HF events found that low SES was associated with an increase in risk of incident HF ranging between 43% and 87% depending on SES measure, with an overall estimate of 62% (hazard ratio [HR] 1.62, 95% CI 1.50-1.76). By individual measure, HRs of 1.66 (95% CI 1.3-2.11), 1.87 (95% CI 1.33-2.62) and 1.54 (95% CI 1.22-1.95) were observed for education, income and occupation respectively. For area-level indexes, HRs were 1.43 (95% CI 1.2-1.69) (Carstairs index) and 1.61 (95% CI 1.56-1.65) (index of multiple deprivation). Conclusion: Low SES assessed by all common measures confers independent risk for incident HF. These findings carry implications for the design and delivery of HF prevention programs. PMID- 30295784 TI - Ustekinumab Is Effective for the Treatment of Crohn's Disease of the Pouch in a Multicenter Cohort. AB - Background: Crohn's disease (CD) of the pouch and chronic pouchitis occur in approximately 10% of patients after ileal pouch-anal anastomosis (IPAA) for refractory ulcerative colitis (UC) or UC-related dysplasia. The efficacy of anti tumor necrosis factor (anti-TNF) agents and vedolizumab have been reported for the treatment of CD of the pouch and chronic pouchitis, but little is known regarding the use of ustekinumab in these settings. Our primary aim was to evaluate the efficacy of ustekinumab for these conditions. Methods: This is a retrospective, multicenter cohort study evaluating the efficacy of ustekinumab in patients with CD of the pouch and chronic pouchitis. Clinical response or remission was judged by the treating physician's assessment at 6 months. Results: Fifty-six patients (47 with CD of the pouch and 9 with chronic pouchitis) were included the study. Of these, 73% had previously been treated with either anti TNF therapy, vedolizumab, or both after IPAA. Among patients with CD of the pouch and chronic pouchitis, 83% demonstrated clinical response 6 months after induction with ustekinumab. Responders demonstrated significantly less pouch inflammation on endoscopy when compared with nonresponders (29% vs 100%; P = 0.023). Higher mean body mass index at induction (26.3 vs 23.7; P = 0.033) and male sex (83% vs 30%; P = 0.014) were significant predictors of nonresponse to ustekinumab in those with CD of the pouch. Conclusion: In this refractory patient population, ustekinumab appears to be a safe and effective treatment for chronic pouchitis and CD of the pouch in biologic-naive patients and those with prior anti-TNF or vedolizumab therapy failure. 10.1093/ibd/izx005_video1izy302.video15844889626001. PMID- 30295786 TI - A Systematic Review of Self-Management Interventions for Children and Adolescents With Inflammatory Bowel Disease. AB - Background: Self-management of inflammatory bowel disease is complex. Children and adolescents (CA) with inflammatory bowel disease (IBD) often have difficulty with managing aspects of their condition, resulting in treatment nonadherence and impaired psychosocial function. Self-management interventions are developed to help support patients and their parents/carers to effectively self-manage. The aim of this systematic review was to evaluate the efficacy of self-management interventions in children and adolescents with IBD. Methods: The review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A systematic literature search of the following databases was conducted to identify controlled trials of interventions aiming to enhance IBD self-management in CA: Medline, Embase, Cochrane, CINAHL, and PsychINFO. Two reviewers screened articles for inclusion. Results: Nine trials (11 articles) met the inclusion criteria. Most were underpowered, with 7 recruiting fewer than 50 participants. The interventions aimed to enhance psychological well-being (n = 5), medication adherence (n = 3), or calcium intake (n = 1). There was considerable heterogeneity in intervention content and outcomes assessment. Some benefits were reported in disease activity, adherence, and psychological well-being, but findings were inconsistent. Conclusions: Self management is difficult for CA with IBD; however, this review identified only a small number of interventions to support self-management, most of which were underpowered and only 1 that was conducted outside the United States. Clinical consensus is required on which self-management activities should be recommended to patients and targeted in interventions and which core outcomes should be assessed. Adequately powered trials of interventions are required to identify how best to support self-management in CA with IBD. PMID- 30295785 TI - A propensity score-matched comparison of infliximab and adalimumab in TNF-alpha inhibitors naive and non-naive patients with Crohn's disease: real-life data from the Sicilian Network for Inflammatory Bowel Disease (SN-IBD). AB - Background and Aims: There is an unmet need to better understand the effectiveness of different biologics in inflammatory bowel diseases. We aimed at performing a multicenter, real-life comparison of the effectiveness of infliximab (IFX) and adalimumab (ADA) in Crohn's disease (CD). Methods: Data of consecutive patients with CD treated with IFX and ADA from January 2013 to May 2017 were extracted from the cohort of the Sicilian Network for Inflammatory Bowel Disease. We used a propensity score matching accounting for the main baseline characteristics in TNF-alpha inhibitor naive and non-naive patients. Results: 632 patients (735 total treatments) were included. Among naive patients, a clinical benefit (the sum of steroid-free remission plus clinical response) was achieved in 81.8% patients treated with ADA and in 77.6% patients treated with IFX (adjusted OR: 1.23, 95%CI 0.63-2-44, p=0.547) at 12 weeks; after one year, a clinical benefit was achieved in 69.2% of patients treated with ADA and in 64.5% patients treated with IFX (adjusted OR: 1.10, 95%CI 0.61-1.96, p=0.766). Among non-naive patients, a clinical benefit was achieved in 61.7% of patients treated with ADA and in 68.1% of patients treated with IFX (adjusted OR: 0.72, 95%CI 0.21 2.44, p=0.600) at 12 weeks; after one year, a clinical benefit was achieved in 48.9% of patients treated with ADA and in 40.4% patients treated with IFX (adjusted OR: 1.23, 95%CI 0.54-2.86, p=0.620). Conclusions: In this propensity score-matched comparison of ADA and IFX in CD, both drugs showed high rates of clinical benefit, without significant differences between them. PMID- 30295787 TI - Structured Illumination Approaches for Super-Resolution in Plant Cells. AB - The advent of super-resolution techniques in biological microscopy has opened new frontiers for exploring the molecular distribution of proteins and small molecules in cells. Improvements in optical design and innovations in the approaches for the collection of fluorescence emission have produced substantial gains in signal from chemical labels and fluorescent proteins. Structuring the illumination to elicit fluorescence from specific or even random patterns allows the extraction of higher order spatial frequencies from specimens labeled with conventional probes. Application of this approach to plant systems for super resolution imaging has been relatively slow owing in large part to aberrations incurred when imaging through the plant cell wall. In this brief review, we address the use of two prominent methods for generating super-resolution images in living plant specimens and discuss future directions for gaining better access to these techniques.

PMID- 30295789 TI - Adult-Onset Hepatocyte GH Resistance Promotes NASH in Male Mice, Without Severe Systemic Metabolic Dysfunction. AB - Nonalcoholic fatty liver disease (NAFLD), which includes nonalcoholic steatohepatitis (NASH), is associated with reduced GH input/signaling, and GH therapy is effective in the reduction/resolution of NAFLD/NASH in selected patient populations. Our laboratory has focused on isolating the direct vs indirect effects of GH in preventing NAFLD/NASH. We reported that chow-fed, adult onset, hepatocyte-specific, GH receptor knockdown (aHepGHRkd) mice rapidly (within 7 days) develop steatosis associated with increased hepatic de novo lipogenesis (DNL), independent of changes in systemic metabolic function. In this study, we report that 6 months after induction of aHepGHRkd early signs of NASH develop, which include hepatocyte ballooning, inflammation, signs of mild fibrosis, and elevated plasma alanine aminotransferase. These changes occur in the presence of enhanced systemic lipid utilization, without evidence of white adipose tissue lipolysis, indicating that the liver injury that develops after aHepGHRkd is due to hepatocyte-specific loss of GH signaling and not due to secondary defects in systemic metabolic function. Specifically, enhanced hepatic DNL is sustained with age in aHepGHRkd mice, associated with increased hepatic markers of lipid uptake/re-esterification. Because hepatic DNL is a hallmark of NAFLD/NASH, these studies suggest that enhancing hepatocyte GH signaling could represent an effective therapeutic target to reduce DNL and treat NASH. PMID- 30295790 TI - Association of the Dundee severity classification with mortality, length of stay and readmission in adult inpatients with cellulitis. AB - Background: The Dundee classification is a simple severity assessment tool that could optimize treatment decisions and clinical outcomes in adult patients with cellulitis; however, it has not been validated in a large cohort. Objectives: To determine whether the Dundee classification reliably identified those patients with cellulitis who had a higher mortality, a longer length of hospital stay or an increased risk of readmission. Methods: We performed a retrospective study of all adults with a primary discharge diagnosis of cellulitis admitted to Auckland City Hospital from August 2013 to June 2015. We classified patients by severity using the Dundee scoring system. Results: The 30 day all-cause mortality in adult patients with a discharge diagnosis of cellulitis was 2% (29/1462) overall, and was 1% (10/806), 2% (6/271), 3% (10/353) and 9% (3/32) in Classes 1, 2, 3 and 4 of the Dundee classification, respectively (P = 0.01). Mortality was strongly associated with age >65 years (OR 9.37, 95% CI 3.00-41.23) and with heart failure (OR 6.16, 95% CI 2.73-14.23). There were significant associations between the Dundee classification and the incidence of bacteraemia, the length of hospital stay and the rate of readmission to hospital. Conclusions: The Dundee classification is a simple, reliable tool that can be easily applied in clinical settings to predict risk of mortality in order to determine which patients can be managed in the community with oral or intravenous therapy, and which require inpatient care. PMID- 30295792 TI - RCPAQAP audit of antimicrobial reporting in Australian and New Zealand laboratories: opportunities for laboratory contribution to antimicrobial stewardship. AB - Objectives: A 2017 laboratory survey conducted by the Royal College of Pathologists of Australasia Quality Assurance Programs (RCPAQAP) asked participants which antimicrobials they would report for given organisms in either blood or urine cultures in order to identify opportunities for improvement of antimicrobial reporting. Methods: Over-reporting was defined as reporting of broad-spectrum antimicrobials on isolates susceptible to narrow-spectrum antimicrobials. Inappropriate reporting was defined as reporting antimicrobials not appropriate for the site of infection. Results: For a fully susceptible Escherichia coli in blood culture, 65% of laboratories (55/84) over-reported at least one antimicrobial. Importantly, 15% (10/65) of laboratories that tested meropenem reported the result. A significant proportion of laboratories (12%, 10/84) reported antimicrobials generally considered inappropriate for treatment of bacteraemia on blood culture isolates. Overall, 82% (77/94) of laboratories either over-reported or inappropriately reported at least one antimicrobial. Conclusions: This survey identifies significant opportunities for improvement and standardization of 'cascade' or 'selective' reporting of antimicrobials and highlights ways in which microbiology laboratories can contribute to antimicrobial stewardship and judicious use of antimicrobials. PMID- 30295793 TI - NLRP3 Inflammasome-Related Proteins Are Upregulated in the Putamen of Patients With Multiple System Atrophy. AB - Multiple system atrophy (MSA) is a neurodegenerative disease characterized by parkinsonism, ataxia, and autonomic dysfunction. Microglial infiltration is an important mediator in MSA. The nucleotide-binding domain, leucine-rich repeats containing family, pyrin domain-containing-3 (NLRP3) inflammasome complex, comprising NLRP3, apoptotic speck protein containing a caspase recruitment domain (ASC), and cysteine aspartic acid protease 1 (Caspase 1), regulates microglial inflammation in several neurodegenerative diseases. However, its role in MSA remains unknown. This study aimed to investigate the role of the NLRP3 inflammasome in MSA. Immunohistochemical staining of postmortem brains from 11 cases of MSA, 5 of Parkinson disease, and 6 age-matched controls were assessed. The relationships among alpha-synuclein deposition, microglial infiltration, and NLRP3 inflammasome-related proteins (NLRP3, ASC, and Caspase 1) were quantitatively analyzed. Double-labeling immunofluorescence staining confirmed colocalization of NLRP3 inflammasome-related proteins and Cluster of Differentiation 68. We demonstrated that the density of microglia expressing NLRP3 inflammasome-related proteins was increased in the putamina of MSA cases and was significantly related to the deposition of phosphorylated alpha-synuclein positive glial cytoplasmic inclusions, tyrosine hydroxylase-positive fiber loss, and gliosis of glial fibrillary acidic protein-positive astrocytes. Our study suggests that the NLRP3 inflammasome is significantly upregulated and correlates with the neurodegenerative process in MSA. PMID- 30295794 TI - Histopathologic Correlates of Familial Hemophagocytic Lymphohistiocytosis Isolated to the Central Nervous System. AB - Familial hemophagocytic lymphohistiocytosis (HLH) is an immune hyperactivation syndrome caused by mutations in genes associated with cytotoxic T-cell and NK cell function. While neurological manifestations frequently accompany systemic inflammation at initial presentation, isolated central nervous system (CNS) involvement is rare, and the histological correlates are not well described. We present 3 patients (ages 5, 6, and 7 years) with CNS-isolated familial HLH, who presented with a variety of neurological symptoms and underwent brain biopsies for multifocal enhancing supratentorial and infratentorial lesions. Biopsy slides from all 3 patients revealed similar findings: perivascular lymphocytes, predominantly CD3+ T-cells (CD4>CD8) with occasional intramural infiltration of small vessels; scattered histiocytes without hemophagocytosis; parenchymal and leptomeningeal inflammation varying from mild and focal to severe and sheet-like with associated destructive lesions. There was no evidence of demyelination, neoplasia, or infection. Genetic testing identified compound heterozygous mutations in PRF1 (Patients 1 and 2) and UNC13D (Patient 3), with no evidence of systemic disease except decreased NK-cell function. All 3 patients were treated with hematopoietic stem cell transplantation with marked improvement of symptoms. These findings combined with the poor outcomes associated with delayed diagnosis and lack of aggressive treatment highlight the need to consider HLH in the differential diagnosis of inflammatory brain lesions. PMID- 30295795 TI - New sternal closure methods versus the standard closure method: systematic review and meta-analysis. AB - OBJECTIVES: This study aimed to evaluate, by means of a systematic review, the efficiency of new methods for sternal closure in order to prevent sternal wound complications after sternotomy. METHODS: The method of study was a systematic review of randomized clinical trials. We included studies that used rigid plates, thermoreactive clips, cables and flat wires, in comparison with the standard closure method. Patients included adults, regardless of gender and race. RESULTS: Seven clinical trials were included involving 1810 patients. Five trials were carried out in the USA, 1 in Australia and 1 in Italy, and the trials include both male and female patients. The included studies compared conventional sternal closure with new closure methods (rigid plate, thermoreactive clips, cables and flat wires). The new sternal closure methods make little or no difference compared to the standard closure when we analyse deep sternal wound infection [risk ratio 0.38, 95% confidence interval (CI) 0.02-7.63; I2 = 74%; 5 studies], superficial wound infection (risk ratio 1.34, 95% CI 0.46-3.92; I2 = 11%, 3 studies) and death (risk ratio 1.16, 95% CI 0.42-3.21; I2 = 0%, 3 studies), but pain score was lower in new sternal closure methods (mean difference -0.57, 95% CI -0.98 to -0.16, I2 = 0%, 3 studies). There were no meta-analyses of sternal union, hospital stay, reoperation or mechanic ventilation time because of the high heterogeneity between the studies in terms of these outcomes. CONCLUSIONS: New sternal closure methods probably make little or no difference regarding the prevention of sternal complications in the postoperative period when compared to the standard closure method.

AB - A randomized controlled trial has been initiated to compare chemotherapy containing dose-dense paclitaxel plus carboplatin with or without bevacizumab to a conventional regimen containing tri-weekly paclitaxel plus carboplatin with or without bevacizumab. Eligible patients are those with stage IVB, recurrent or persistent cervical carcinoma not amenable to curative treatment with local therapy. Patients are randomly assigned to either the conventional or dose-dense regimen. However, patients who are at increased risk of adverse events following bevacizumab administration will not receive this drug. The primary endpoint of phase II part is response rate. If the response rate of the dose-dense regimen is better than that of conventional regimen, this study will proceed to phase III, where the primary endpoint is overall survival. Secondary endpoints in phase III part are progression-free survival, response rates, adverse events, serious adverse events and the proportion of non-hospitalization periods compared with planned treatment periods. PMID- 30295798 TI - Real-world implications of QT prolongation in patients receiving voriconazole and amiodarone. AB - Objectives: Voriconazole, a triazole antifungal, is frequently prescribed in a complex patient population with comorbidities that require concomitant administration of QT interval-prolonging medications. We sought to evaluate QT interval prolongation in patients receiving concomitant therapy with voriconazole and amiodarone and to assess the development of any potentially fatal cardiac arrhythmias as a result. Methods: We conducted a retrospective observational study of patients who had received amiodarone and voriconazole concomitantly between 2005 and 2015, with a prior period of monotherapy, who had ECG data during monotherapy (baseline) and concomitant therapy (follow-up). Results: We included 46 patients in our final analysis. Overall, the mean change in QT corrected (QTc) from baseline to follow-up was 49.0 ms (P < 0.001). Eighteen (39.1%) patients had a follow-up QTc interval >=500 ms, with 17 (37.0%) having a change in QTc interval >=60 ms from baseline to follow-up. Men were more likely to have a follow-up QTc interval of >=500 ms. In multivariate analysis, only low serum potassium concentration and concomitant 'possible' QT-prolonging drugs were associated with a follow-up QTc interval >=500 ms and a lower baseline QTc interval was associated with a change in QTc interval of >=60 ms. Discharge diagnoses of cardiac arrhythmias and events were assessed and none was found to be related to concomitant therapy. Conclusions: Concomitant therapy with amiodarone and voriconazole significantly prolonged the QTc interval to a degree greater than that on monotherapy. However, no clinically significant cardiac events were observed. PMID- 30295800 TI - Corrigendum.

PMID- 30295799 TI - IgG4-related disease: a new challenging diagnosis mimicking lung cancer. AB - IgG4-related disease (IgG4-RD) is a progressive inflammatory disease that might rarely involve only the lungs. We retrospectively reviewed the preoperative, clinical and surgical features of patients with a pathology highly suggestive or probable diagnosis of IgG4-RD without extra-thoracic involvement. Five patients were selected, 2 were operated on the right side. Positron emission tomography computed tomography (PET-CT) showed an uptake in all the patients (median 5.5), and 2 patients had an uptake at the thoracic lymph nodes. Two diagnoses were made through a CT-guided needle biopsy, while 3 were determined based on a lung wedge resection. The levels of serum IgG4 were elevated (>1.35 g/dl) in all the patients. Two patients had a highly suggestive diagnosis of IgG4-RD, and 3 patients had a probable diagnosis of IgG4-RD. The differential diagnosis between IgG4-RD and lung malignancies based only on radiological features is challenging and often requires histological confirmation. A careful preoperative workup and a multidisciplinary approach to PET-positive nodules might help to avoid unnecessary major lung resections. PMID- 30295802 TI - Integrative genomic analysis reveals novel regulatory mechanisms of eyeless during Drosophila eye development. AB - Eyeless (ey) is one of the most critical transcription factors for initiating the entire eye development in Drosophila. However, the molecular mechanisms through which Ey regulates target genes and pathways have not been characterized at the genomic level. Using ChIP-Seq, we generated an endogenous Ey-binding profile in Drosophila developing eyes. We found that Ey binding occurred more frequently at promoter compared to non-promoter regions. Ey promoter binding was correlated with the active transcription of genes involved in development and transcription regulation. An integrative analysis revealed that Ey directly regulated a broad and highly connected genetic network, including many essential patterning pathways, and known and novel eye genes. Interestingly, we observed that Ey could target multiple components of the same pathway, which might enhance its control of these pathways during eye development. In addition to protein-coding genes, we discovered Ey also targeted non-coding RNAs, which represents a new regulatory mechanism employed by Ey. These findings suggest that Ey could use multiple molecular mechanisms to regulate target gene expression and pathway function, which might enable Ey to exhibit a greater flexibility in controlling different processes during eye development. PMID- 30295801 TI - Mapping interfacial hydration in ETS-family transcription factor complexes with DNA: a chimeric approach. AB - Hydration of interfaces is a major determinant of target specificity in protein/DNA interactions. Interfacial hydration is a highly variable feature in DNA recognition by ETS transcription factors and functionally relates to cellular responses to osmotic stress. To understand how hydration is mediated in the conserved ETS/DNA binding interface, secondary structures comprising the DNA contact surface of the strongly hydrated ETS member PU.1 were substituted, one at a time, with corresponding elements from its sparsely hydrated relative Ets-1. The resultant PU.1/Ets-1 chimeras exhibited variably reduced sensitivity to osmotic pressure, indicative of a distributed pattern of interfacial hydration in wildt-ype PU.1. With the exception of the recognition helix H3, the chimeras retained substantially high affinities. Ets-1 residues could therefore offset the loss of favorable hydration contributions in PU.1 via low-water interactions, but at the cost of decreased selectivity at base positions flanking the 5'-GGA-3' core consensus. Substitutions within H3 alone, which contacts the core consensus, impaired binding affinity and PU.1 transactivation in accordance with the evolutionary separation of the chimeric residues involved. The combined biophysical, bioinformatics and functional data therefore supports hydration as an evolved specificity determinant that endows PU.1 with more stringent sequence selection over its ancestral relative Ets-1. PMID- 30295803 TI - Trajectories and Predictors of Longitudinal Preexposure Prophylaxis Adherence Among Men Who Have Sex With Men. AB - Background: Adherence is necessary for efficacy of preexposure prophylaxis (PrEP), and text-messaging methods are promising tools for both adherence assessment and support. Although PrEP adherence is variable, little research has examined patterns of variability or factors associated with longitudinal use. Methods: In the context of a randomized controlled trial of text-messaging versus standard of care for PrEP adherence, 181 men who have sex with men received once daily tenofovir disoproxil fumarate/emtricitabine and daily adherence texts for 48 weeks. Growth mixture modeling (GMM) was used to identify subgroups of individuals with similar trajectories of text-reported adherence. Between-group differences in pharmacologic measures of adherence (ie, tenofovir diphosphate and emtricitabine triphosphate levels), as well as predictors and study-end attitudes associated with group membership, were examined. Results: GMM identified 4 trajectories of text-reported adherence. Classes with higher text-reported adherence had higher drug concentrations. Younger age and minority race were associated with lower adherence, and individuals in classes with lower adherence had greater baseline levels of depression, substance use concerns, and sexual risk. Differences in study satisfaction were also associated with adherence. Conclusions: This study supports the use of text-reported PrEP adherence. Identifying factors associated with less-than-optimal adherence may aid clinicians in anticipating at-risk patients requiring augmented intervention. Clinical trials registration: NCT01761643. PMID- 30295804 TI - Non-malignant and malignant meningioma incidence and survival in the elderly from 2005-2015 using the Central Brain Tumor Registry of the United States. AB - Background: Meningioma incidence increases significantly with age. In the expanding elderly population, we lack complete understanding of population-based trends in meningioma incidence/survival. We provide an updated, comprehensive analysis of meningioma incidence and survival for individuals aged over 65. Methods: Data were obtained from the Central Brain Tumor Registry of the United States (CBTRUS) from 2005-2015 for non-malignant and malignant meningioma. Age adjusted incidence rates per 100,000 person-years were analyzed by age, sex, race, ethnicity, location, and treatment modalities. Survival was analyzed using Kaplan-Meier and multivariable Cox proportional hazards models for a subset of CBTRUS data. Results: Non-malignant meningioma incidence doubled from adults age 65-69 years to adults over age 85 years and was significantly greater in females than males for all ages. Malignant meningioma incidence did not differ by sex for any age grouping. Non-malignant and malignant meningioma incidence was significantly greater in Black populations versus others. Non-malignant meningioma survival was worse with age, in Black populations, and in males, including when analyzed by five-year age groups. Surgical resection and radiation did not improve survival compared to resection alone in non-malignant meningioma. Conclusions: This study reports increasing non-malignant meningioma incidence in the elderly, increased incidence in Black populations, and in females. In contrast, malignant meningioma incidence did not differ between sexes. Risk of death was higher for Black individuals and males. Additionally, radiation did not confer a survival advantage when combined with resection for non-malignant meningioma. Thus, we identify clinically relevant discrepancies in meningioma incidence/survival that require further study. PMID- 30295805 TI - Quality assessment indicators in antenatal care worldwide: a systematic review. AB - Purpose: To describe indicators used for the assessment of antenatal care (ANC) quality worldwide under the World Health Organization (WHO) framework and based on a systematic review of the literature. Data sources: Searches were performed in MEDLINE, SciELO, BIREME and Web of Science for eligible studies published between January 2002 and September 2016. Study selection: Original articles describing women who had received ANC, any ANC model and, any ANC quality indicators were included. Data extraction: Publication date, study design and ANC process indicators were extracted. Results of data synthesis: Of the total studies included, 69 evaluated at least one type of ANC process indicator. According to WHO ANC guidelines, 8.7% of the articles reported healthy eating counseling and 52.2% iron and folic acid supplementation. The evaluation indicators on maternal and fetal interventions were: syphilis testing (55.1%), HIV testing (47.8%), gestational diabetes mellitus screening (40.6%) and ultrasound (27.5%). Essential ANC activities assessment ranged from 26.1% report of fetal heart sound, 50.7% of maternal weight and 63.8% of blood pressure. Regarding preventive measures recommended by WHO, tetanus vaccine was reported in 60.9% of the articles. Interventions performed by health services to improve use and quality of ANC care, promotion of maternal and fetal health, and the number of visits to the ANC were evaluated in 65.2% of the studies. Conclusion: Numerous ANC content indicators are being used to assess ANC quality. However, there is a need to use standardized indicators across countries and efforts to improve quality evaluation. PMID- 30295806 TI - Fatal Granulomatous Amebic Encephalitis in a Heart Transplant Patient: Clinical, Radiographic, and Autopsy Findings. AB - Granulomatous amebic encephalitis is a rare necrotizing infection of the CNS that occurs most commonly in immunocompromised individuals and is usually fatal. It is difficult to diagnose as the clinical symptoms and radiographic findings are often mistaken for other bacterial, viral, fungal, or protozoan infections. Herein, we present the case of a 69-year-old heart transplant recipient who suffered fulminant neurological decline ~5 months after transplant. Extensive radiographic and laboratory testing did not provide a definite anatomic diagnosis and, despite aggressive clinical treatment, he died. An autopsy examination demonstrated numerous brain abscesses which contained amebic trophozoites and cysts. An indirect immunofluorescence assay performed at the Centers for Disease Control confirmed the presence of Acanthamoeba species. To the best of our knowledge, only 13 other cases of Acanthamoeba amebic encephalitis have been reported in patients who have received solid organ transplants and this is the second case reported in a heart transplant recipient. This case emphasizes that amebic encephalitis should be in the differential diagnosis for immunocompromised patients with new brain lesions found on radiographic imaging.

PMID- 30295809 TI - Detection of Drugs in Simultaneously Collected Samples of Oral Fluid and Blood. AB - Simultaneously collected samples of oral fluid and blood in a naturalistic setting could provide a qualitative impression of the relative detection times of drugs in oral fluid compared to blood. The aim of this study was to compare detections of different drugs in oral fluid and blood from a large material of paired samples. The study included results from 930 paired oral fluid and blood samples collected from drivers suspected for driving under the influence of drugs. Oral fluid was collected using the Intercept device. Blood samples were screened using an ultra high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS-MS) method and positive results were confirmed and quantified with a different analytical method. Oral fluid samples were analyzed using UHPLC-MS-MS. The drugs included in the study were: amphetamine, methamphetamine, tetrahydrocannabinol (THC), diazepam, N-desmethyldiazepam, clonazepam, alprazolam, nitrazepam, oxazepam, morphine, 6-monoacetylmorphine (6 MAM), methadone and buprenorphine. The drugs detected more frequently in oral fluid compared to blood were amphetamine (497 positive in oral fluid/408 positive in blood), methamphetamine (332/232), oxazepam (106/36), morphine (65/31) and 6 MAM (19/0). The drugs detected less frequently in oral fluid compared to blood were THC (224 positive in oral fluid/407 positive in blood), diazepam (137/160), N-desmethyldiazepam (183/188), clonazepam (148/307), alprazolam (47/68), nitrazepam (16/29) and buprenorphine (31/59). For methadone, the number of detections was the same in oral fluid and in blood (23/23). The results indicate that for amphetamine, methamphetamine, morphine and 6-MAM, relative detection time is longer in oral fluid than in blood, while for benzodiazepines, the results indicate that relative detection time is shorter in oral fluid than in blood. For oxazepam and buprenorphine, the results were dependent on the cut-off limits used. Regarding THC, the detection time in oral fluid depends on the sampling method. The relative detection time was shorter than in blood when using the Intercept device. PMID- 30295807 TI - Treatments targeting inotropy. AB - Acute heart failure (HF) and in particular, cardiogenic shock are associated with high morbidity and mortality. A therapeutic dilemma is that the use of positive inotropic agents, such as catecholamines or phosphodiesterase-inhibitors, is associated with increased mortality. Newer drugs, such as levosimendan or omecamtiv mecarbil, target sarcomeres to improve systolic function putatively without elevating intracellular Ca2+. Although meta-analyses of smaller trials suggested that levosimendan is associated with a better outcome than dobutamine, larger comparative trials failed to confirm this observation. For omecamtiv mecarbil, Phase II clinical trials suggest a favourable haemodynamic profile in patients with acute and chronic HF, and a Phase III morbidity/mortality trial in patients with chronic HF has recently begun. Here, we review the pathophysiological basis of systolic dysfunction in patients with HF and the mechanisms through which different inotropic agents improve cardiac function. Since adenosine triphosphate and reactive oxygen species production in mitochondria are intimately linked to the processes of excitation-contraction coupling, we also discuss the impact of inotropic agents on mitochondrial bioenergetics and redox regulation. Therefore, this position paper should help identify novel targets for treatments that could not only safely improve systolic and diastolic function acutely, but potentially also myocardial structure and function over a longer-term. PMID- 30295810 TI - Effect of exogenous butyrate on the gastrointestinal tract of sheep. I. Structure and function of the rumen, omasum, and abomasum. AB - The aim of this study was to determine the effect of exogenous butyrate on the structure and selected functions of the stomach in sheep. Eighteen rams (30.8 +/- 2.1 kg; 12 to 15 mo of age) were allocated to the study and fed a diet for 14 d without (CTRL) or with sodium butyrate (BUT; 36 g/kg of offered DM). Neither DMI nor initial BW differed between treatments (P >= 0.61), but final BW was greater for BUT compared with CTRL (P = 0.03). Butyrate concentration in the reticuloruminal fluid and abomasal digesta was greater for BUT compared with CTRL (P <= 0.01), but total short-chain fatty acids (SCFA) concentration, as well as concentration of other SCFA, did not differ between treatments (P >= 0.07). Relative to BW, reticuloruminal tissue mass tended (P = 0.09) to be greater and omasal digesta was less (P = 0.02) for BUT compared with CTRL. Dietary butyrate did not affect ruminal papillae length, width, and density nor did it affect ruminal epithelium thickness (P >= 0.12) in the ventral sac of the rumen. However, the DM of ruminal epithelium (mg/cm2) tended (P = 0.06) to be greater for BUT compared with CTRL. Omasal and abomasal epithelium thicknesses were greater (P <= 0.05) for BUT compared with CTRL. Mitosis-to-apoptosis ratio in the abomasal epithelium was less for BUT compared with CTRL (P = 0.04). Finally, the mRNA expression of peptide transporter 1 in the omasal epithelium was less (P = 0.02) and mRNA expression of monocarboxylate transporter 1 in the abomasal epithelium tended (P = 0.07) to be greater for BUT compared with CTRL. It can be concluded that exogenous butyrate supplementation affected not only the rumen but also omasum and abomasum in sheep. PMID- 30295811 TI - Fecal Calprotectin Responses Following Induction Therapy With Vedolizumab in Moderate to Severe Ulcerative Colitis: A Post Hoc Analysis of GEMINI 1. AB - Background: In patients with ulcerative colitis (UC), fecal calprotectin (FC) concentrations correlate with endoscopic inflammation evidence. This study investigated the effect of vedolizumab induction on FC concentrations and whether FC concentrations could be a reliable surrogate measure of disease status. Methods: Data from the placebo-controlled, phase 3 trial GEMINI 1 were used to evaluate week-6 relationships between outcomes (including clinical remission, mucosal healing [MH], and endoscopic remission) and both absolute FC concentration values and relative FC concentration changes from baseline (%FC0 6). Sensitivity and specificity were calculated by cross-tabulation; the value of week-6 FC concentration as surrogate biomarker was measured with Youden J statistic computed for various cut points. Results: GEMINI 1 induction phase enrolled 895 patients. Fecal calprotectin concentration decreases were deeper in patients with clinical remission, MH, and/or endoscopic remission than in patients without. The best week-6 indicator of clinical or endoscopic remission in this data set was absolute FC concentration <=150 ug/g. The surrogate biomarker values (based on areas under the curve) for the best-performing cut points (FC0-6 reduction >90%, FC <=150 ug/g) were fair (range, 0.70-0.77, total population). More patients met the <=150 ug/g cut point with vedolizumab than with placebo. Baseline FC concentrations were not correlated with clinical outcomes. Conclusions: Fecal calprotectin concentration reductions were greater with vedolizumab induction than with placebo. Week-6 FC concentrations had only fair surrogate biomarker value for endoscopic status. Our data suggest that, while FC may reflect inflammatory burden, FC concentration after vedolizumab induction may not be a robust biomarker of mucosal inflammation. PMID- 30295812 TI - Illuminating Endocrine Evolution: The Power and Potential of Large-Scale Comparative Analyses. AB - Hormones are central mediators of genotype-phenotype and organism-environment interactions. Despite these important functions, the role of selection in shaping hormonal mediators of phenotype remains poorly understood. Thanks to decades of work by endocrinologists, circulating hormone levels have been measured in a diversity of organisms. Variation in other endocrine traits and mediators (e.g., receptor expression and binding globulins), and the hormonal response to standardized challenges (e.g., restraint, pharmacological challenges) are also increasingly measured in both captive and free-living populations. Large-scale comparative analyses of the multitude of available endocrine data represent a particularly promising approach to addressing the function and evolution of these key phenotypic mediators, and their potential to serve as indicators of disturbance. Several recent phylogenetic comparative analyses and meta-analyses have begun to reveal the power and potential of these approaches to address key questions in integrative biology. Here we highlight two recent developments that are facilitating such analyses: increasingly powerful and flexible phylogenetic comparative methods, and the release of two endocrine trait databases-HormoneBase (currently 474 species) and the Wildlife Endocrinology Information Network (currently 25 species)-that contain compiled measures of endocrine traits across vertebrates. Increasingly comprehensive comparative analyses of endocrine data could provide insight into many interesting questions, including how rapidly changing environments are impacting phenotypes, why endocrine traits differ so remarkably within and across populations, and the evolution of plasticity. The endocrine system mediates interactions between genotypes and phenotypes, and between organisms and their environment. Environmentally induced hormonal responses regulate phenotypic flexibility across timescales by altering physiological state, gene expression, and epigenetic marks. A staggering diversity of phenotypic traits are mediated by hormones from early development through senescence. Through their actions on behavior, hormones also exert widespread influence over how organisms interact with their biotic and abiotic environments. Because hormones are responsive to the environment, there has long been interest in their use as biomarkers of exposure to challenges. More recently, increasing attention has been paid to the potential for within and among-population variation in endocrine regulation or responsiveness to serve as indicators of resistance or resilience to future challenges, or measures of evolutionary potential. PMID- 30295813 TI - The Temporal and Environmental Context of Early Animal Evolution: Considering All the Ingredients of an "Explosion". AB - Animals originated and evolved during a unique time in Earth history-the Neoproterozoic Era. This paper aims to discuss (1) when landmark events in early animal evolution occurred, and (2) the environmental context of these evolutionary milestones, and how such factors may have affected ecosystems and body plans. With respect to timing, molecular clock studies-utilizing a diversity of methodologies-agree that animal multicellularity had arisen by ~800 million years ago (Ma) (Tonian period), the bilaterian body plan by ~650 Ma (Cryogenian), and divergences between sister phyla occurred ~560-540 Ma (late Ediacaran). Most purported Tonian and Cryogenian animal body fossils are unlikely to be correctly identified, but independent support for the presence of pre-Ediacaran animals is recorded by organic geochemical biomarkers produced by demosponges. This view of animal origins contrasts with data from the fossil record, and the taphonomic question of why animals were not preserved (if present) remains unresolved. Neoproterozoic environments demanding small, thin, body plans, and lower abundance/rarity in populations may have played a role. Considering environmental conditions, geochemical data suggest that animals evolved in a relatively low oxygen ocean. Here, we present new analyses of sedimentary total organic carbon contents in shales suggesting that the Neoproterozoic ocean may also have had lower primary productivity-or at least lower quantities of organic carbon reaching the seafloor-compared with the Phanerozoic. Indeed, recent modeling efforts suggest that low primary productivity is an expected corollary of a low O2 world. Combined with an inability to inhabit productive regions in a low-O2 ocean, earliest animal communities would likely have been more food limited than generally appreciated, impacting both ecosystem structure and organismal behavior. In light of this, we propose the "fire triangle" metaphor for environmental influences on early animal evolution. Moving toward consideration of all environmental aspects of the Cambrian radiation (fuel, heat, and oxidant) will ultimately lead to a more holistic view of the event.

PMID- 30295816 TI - HPT-Axis Effects and Urinary Detection Following Clomiphene Administration in Males. AB - Context: Clomiphene is a commonly abused performance-enhancing drug by males in sport, but the extent to which testosterone increases in healthy males following its use is unknown. Additionally, evidence has suggested that clomiphene, a mixture of cis- and trans-isomers zuclomiphene and enclomiphene, is detectable in urine for months following use; the isomer-specific urinary detection window has yet to be characterized in a controlled study. Objective: To determine the effect of a once daily, 30-day clomiphene treatment on serum testosterone and gonadotropins in the subject population studied, and the urinary clearance and detection window of clomiphene isomers following administration for anti-doping purposes. Participants and Design: Twelve healthy males aged 25 to 38, representing a recreational athlete population, participated in this open-label, single-arm study. Intervention: Oral clomiphene citrate (50 mg) was self administered once daily for 30 days. Serum and urine samples were collected at baseline and at Day 7, 14, 21, 28, 30, 32, 35, 37, 44, 51, and 58; urine collections continued periodically up to Day 261. Results: Testosterone, LH, and FSH increased 146% (+/- 23% SEM), 177% (+/- 34%), and 170% (+/- 33%), respectively, during treatment compared to baseline. Serum drug concentrations and urinary excretion were non-uniform amongst individuals as isomeric concentrations varied. The zuclomiphene urinary detection window ranged from 121 to greater than 261 days. Conclusions: Clomiphene significantly raises serum testosterone and gonadotropins in healthy men and thus can be abused as a performance-enhancing drug. Such abuse is detectable in urine for four months or greater following short-term use. PMID- 30295817 TI - A Wolf in Sheep's Clothing. PMID- 30295818 TI - Herpes Zoster Incidence in Inflammatory Bowel Disease Patients: A Population Based Study. AB - Background: The aberrant immune response in inflammatory bowel disease (IBD) and immunosuppression may intrinsically predispose patients to infectious complications, such as herpes zoster (HZ). We quantified the incidence of HZ in IBD patients in the province of Quebec, Canada. Methods: We performed a descriptive study using the provincial "Regie de l'Assurance Maladie du Quebec" (RAMQ) health registry from 1996 to 2015. The study population consisted of all subjects in the source population who fulfilled the CD and UC case-defining criteria. HZ incidence rates (IRs) in person-years (py) were calculated according to age groups, sex, Charlson Comorbidity index (CCI), and IBD type. Age standardized incidence ratios (SIRs) were performed using the Quebec general population as reference. Results: A total of 39,366 patients met the diagnostic criteria of either Crohn's disease (CD; n = 23,388), ulcerative colitis (UC; n = 14,513), or IBD unclassified (n = 1465). We identified 2158 HZ cases. Crude IR was 6.67 cases/1000 py and 7.22 cases/1000 py for CD and UC patients, respectively. Unclassified IBD crude HZ IR was 7.54 cases/1000 py. No significant time trend was identified. HZ incidence is high in IBD patients >50 years of age and among the very young (0-17 years of age; SIR, 3.38; 95% confidence interval, 2.64-4.26), especially females. Conclusions: These data suggest that HZ incidence is high in the IBD population. Preventives measures should be implemented in this at-risk population. PMID- 30295819 TI - Identification of new high affinity targets for Roquin based on structural conservation. AB - Post-transcriptional gene regulation controls the amount of protein produced from a specific mRNA by altering both its decay and translation rates. Such regulation is primarily achieved by the interaction of trans-acting factors with cis regulatory elements in the untranslated regions (UTRs) of mRNAs. These interactions are guided either by sequence- or structure-based recognition. Similar to sequence conservation, the evolutionary conservation of a UTR's structure thus reflects its functional importance. We used such structural conservation to identify previously unknown cis-regulatory elements. Using the RNA folding program Dynalign, we scanned all UTRs of humans and mice for conserved structures. Characterizing a subset of putative conserved structures revealed a binding site of the RNA-binding protein Roquin. Detailed functional characterization in vivo enabled us to redefine the binding preferences of Roquin and identify new target genes. Many of these new targets are unrelated to the established role of Roquin in inflammation and immune responses and thus highlight additional, unstudied cellular functions of this important repressor. Moreover, the expression of several Roquin targets is highly cell-type-specific. In consequence, these targets are difficult to detect using methods dependent on mRNA abundance, yet easily detectable with our unbiased strategy. PMID- 30295820 TI - Unstructured brainstorming is not enough: structured brainstorming based on four verification and validation questions yields better hazard identification in healthcare. AB - Objectives: (1) To introduce the Methodical Hazard Identification Checklist (MHIC) for structured brainstorming and the four V&V categories on which it is based, and (2) to compare its efficacy with that of brainstorming (BS) in identifying hazards in healthcare. Design: Comparative analysis of MHIC and team BS results. Setting: Baruch Padeh Medical Center, Poriya, Israel. Study participants: Quality engineering students, facilitators, validation teams and hospital staff who were familiar with the specific processes. Intervention(s): The number of hazards identified by team BS were compared with those deduced by applying the four V&V hazard categories to each step (the MHIC) of 10 medical and 12 administrative processes. Main Outcome Measure(s): The total number of hazards (1) identified by BS, (2) identified by MHIC, (3) validated by the validation team and (4) hazards identified by both methods that the validation team deemed unreasonable. Results: MHIC was significantly more successful than BS in identifying all hazards for the 22 processes (P < 0.0001). The estimated probabilities of success for BS for administrative and medical processes were 0.4444, 95%CI = [0.3506, 0.5424] and 0.3080, 95%CI = [0.2199, 0.4127], respectively. The estimated probabilities of success for MHIC for administrative and medical processes were 0.9885, 95%CI = [0.9638, 0.9964] and 0.9911, 95%CI = [0.9635, 0.9979], respectively. Conclusions: Compared to traditional BS, MHIC performs much better in identifying prospective hazards in the healthcare system. We applied MHIC methodology to administrative and medical processes and believe it can also be used in other industries that require hazard identification.

AB - Endothelial NO synthase (eNOS) expression is regulated by a number of transcriptional and post-transcriptional mechanisms, but the effects of competing endogenous RNAs (ceRNAs) on eNOS mRNA and the underlying mechanisms are still unknown. Our bioinformatic analysis revealed three highly expressed eNOS targeting miRNAs (miR-15b, miR-16, and miR-30b) in human endothelial cells (ECs). Among the 1103 mRNA targets of these three miRNAs, 15 mRNAs share a common disease association with eNOS. Gene expression and correlation analysis in patients with cardiovascular diseases identified insulin receptor substrate 2 (IRS2) as the most correlated eNOS-ceRNA. The expression levels of eNOS and IRS2 were coincidentally increased by application of laminar shear but reduced with eNOS or IRS2 siRNA transfection in human ECs, which was impeded by Dicer siRNA treatment. Moreover, luciferase reporter assay showed that these three miRNAs directly target the 3'-UTR of eNOS and IRS2. Overexpression of these three miRNAs decreased, whereas inhibition of them increased, both mRNA and protein levels of eNOS and IRS2. Functionally, silencing eNOS suppressed the Akt signal pathway, while IRS2 knockdown reduced NO production in ECs. Thus, we identified eNOS and IRS2 as ceRNAs and revealed a novel mechanism explaining the coincidence of metabolic and cardiovascular diseases.

PMID- 30295822 TI - Asymptomatic Natural Human Infections With the Simian Malaria Parasites Plasmodium cynomolgi and Plasmodium knowlesi. AB - Background: In Southeast Asia, Plasmodium knowlesi, a parasite of long-tailed macaques (Macaca fascicularis), is an important cause of human malaria. Plasmodium cynomolgi also commonly infects these monkeys, but only one naturally acquired symptomatic human case has been reported previously. Methods: Malariometric studies involving 5422 subjects (aged 6 months to 65 years) were conducted in 23 villages in Pailin and Battambang, western Cambodia. Parasite detection and genotyping was conducted on blood samples, using high-volume quantitative PCR (uPCR). Results: Asymptomatic malaria parasite infections were detected in 1361 of 14732 samples (9.2%). Asymptomatic infections with nonhuman primate malaria parasites were found in 21 individuals living close to forested areas; P. cynomolgi was found in 11, P. knowlesi was found in 8, and P. vivax and P. cynomolgi were both found in 2. Only 2 subjects were female, and 14 were men aged 20-40 years. Geometric mean parasite densities were 3604 parasites/mL in P. cynomolgi infections and 52488 parasites/mL in P. knowlesi infections. All P. cynomolgi isolates had wild-type dihydrofolate reductase genes, in contrast to the very high prevalence of mutations in the human malaria parasites. Asymptomatic reappearance of P. cynomolgi occurred in 2 subjects 3 months after the first infection. Conclusions: Asymptomatic naturally acquired P. cynomolgi and P. knowlesi infections can both occur in humans. Clinical Trials Registration: NCT01872702.

AB - Quality issue: Quality assessment is challenging in children with developmental disorders. Previously, a set of quality indicators (QIs) was developed and analyzed in terms of feasibility of use with patients with attention deficit/hyperactivity disorder (ADHD). QI assessment turned out to be possible but highly complex. Thus, we compared different technologies for automated extraction of data for assessment of QIs. Choice of solution: Four automated extraction technologies (regular expressions, Apache Solr, Apache Mahout, Apache OpenNLP) were compared with respect to their properties regarding the complexity of implementing the QI, the complexity of implementing a check module, the reliability and quality of results, the complexity of preparation of interdisciplinary medical reports, and the complexity of deployment and installation. Implementation: Twenty medical reports from different institutions were reviewed for compliance with three QIs by these technologies and compared with expert opinions. Evaluation: Among the four technologies, Apache Solr had the best overall performance. For manual extraction of the three QIs, at least 77 s were necessary per medical report, whereas the prototype evaluated and extracted the QIs automatically in 8 s on average. Unexpectedly, different assessments of the degree of compliance by the experts turned out to be one of the stumbling blocks. An in-depth evaluation compared results on a semantic level. Lessons learned: It is possible to extract QIs by post-processing automated technologies. This approach can also be applied to other developmental disorders. However, a more uniform documentation throughout institutions involved will be necessary in order to implement this method in daily practice. PMID- 30295825 TI - Application of machine learning algorithms for the differential diagnosis of peroxisomal disorders. AB - We have established diagnostic thresholds of very long-chain fatty acids (VLCFA) for the differential diagnosis of peroxisomal disorders using the machine learning tools. The plasma samples of 131 controls and 90 cases were tested for VLCFA using Gas chromatography-Mass spectrometry following stable isotope dilution. This data was used to construct association rules and for recursive partitioning. The C26/22 in healthy controls ranged between 0.008 - 0.01. The C26 levels between 1.61 - 3.34 umol/L and C26/C22 between 0.05 - 0.10 are diagnostic of X-linked adrenoleukodystrophy (X-ALD). Very high levels of C26 (> 3.34 umol/L) and C26/C22 ratio (>0.10) are diagnostic of Zellweger syndrome (ZS). Significant elevation of phytanic acid was observed in Refsum (t = 6.14, p < 0.0001) and Rhizomelic chondrodysplasia punctata (RCDP) (t = 16.72, p < 0.0001). The C26/C22 ratio is slightly elevated in RCDP (t = 2.58, p = 0.01) while no such elevation was observed in Refsum disease (t = 0.86, p = 0.39). The developed algorithm exhibited greater clinical utility (AUC: 0.99 - 1.00) in differentiating X-ALD, ZS, and healthy controls. The algorithm has greater clinical utility in the differential diagnosis of peroxisomal disorders based on VLCFA pattern. Plasmalogens will add additional value in differentiating RCDP and Refsum disease.

AB - Ehrlichia chaffeensis (Rickettsiales: Anaplasmatacae), an understudied bacterial pathogen emerging in the eastern United States, is increasing throughout the range of its vector, the lone star tick [Amblyomma americanum, L. (Acari: Ixodidae)]. To mitigate human disease risk, we must understand what factors drive E. chaffeensis prevalence. Here, we report patterns of E. chaffeensis prevalence in southeastern Virginia across 4 yr and ask how seasonal weather patterns affect variation in rates of E. chaffeensis occurrence. We collected A. americanum nymphs at 130 plots across southeastern Virginia in 2012, 2013, 2015, and 2016, and used polymerase chain reaction and gel electrophoresis to test for the presence of E. chaffeensis DNA. Prevalence estimates varied among years, ranging from 0.9% to 3.7%, and persistence of E. chaffeensis occurrence varied across space, with some sites never testing positive, and one site testing positive every year. Using generalized linear mixed-effects models, we related E. chaffeensis occurrence to temperature, humidity, vapor-pressure deficit, and precipitation during seasons up to 21 mo prior to sampling. Surprisingly, all support was lent to a positive effect of temperature during the previous fall and winter (i.e., prior to the nymphs' hatching), which we hypothesize to influence reservoir host population dynamics through changes to mortality or natality. Although further work is necessary to truly elucidate the mechanisms at play, our study shows E. chaffeensis distribution to be very dynamic across multiple dimensions, demanding broad concerted monitoring efforts that can consider both space and time.

PMID- 30295827 TI - Panel sequencing distinguishes monogenic forms of nephritis from nephrosis in children. AB - Background: Alport syndrome (AS) and atypical hemolytic-uremic syndrome (aHUS) are rare forms of chronic kidney disease (CKD) that can lead to a severe decline of renal function. Steroid-resistant nephrotic syndrome (SRNS) is more common than AS and aHUS and causes 10% of childhood-onset CKD. In recent years, multiple monogenic causes of AS, aHUS and SRNS have been identified, but their relative prevalence has yet to be studied together in a typical pediatric cohort of children with proteinuria and hematuria. We hypothesized that identification of causative mutations by whole exome sequencing (WES) in known monogenic nephritis and nephrosis genes would allow distinguishing nephritis from nephrosis in a typical pediatric group of patients with both proteinuria and hematuria at any level. Methods: We therefore conducted an exon sequencing (WES) analysis for 11 AS, aHUS and thrombotic thrombocytopenic purpura-causing genes in an international cohort of 371 patients from 362 families presenting with both proteinuria and hematuria before age 25 years. In parallel, we conducted either WES or high-throughput exon sequencing for 23 SRNS-causing genes in all patients. Results: We detected pathogenic mutations in 18 of the 34 genes analyzed, leading to a molecular diagnosis in 14.1% of families (51 of 362). Disease-causing mutations were detected in 3 AS-causing genes (4.7%), 3 aHUS-causing genes (1.4%) and 12 NS-causing genes (8.0%). We observed a much higher mutation detection rate for monogenic forms of CKD in consanguineous families (35.7% versus 10.1%). Conclusions: We present the first estimate of relative frequency of inherited AS, aHUS and NS in a typical pediatric cohort with proteinuria and hematuria. Important therapeutic and preventative measures may result from mutational analysis in individuals with proteinuria and hematuria. PMID- 30295829 TI - Is a modified Global Trigger Tool method using automatic trigger identification valid when measuring adverse events?: A comparison of review methods using automatic and manual trigger identification. AB - Objectives: To evaluate a modified Global Trigger Tool (GTT) method with manual review of automatic triggered records to measure adverse events. Design: A cross sectional study was performed using the original GTT method as gold standard compared to a modified GTT method. Setting: Medium size hospital trust in Northern Norway. Participants: One thousand two hundred thirty-three records selected between March and December 2013. Main outcome measure: Records with triggers, adverse events and number of adverse events identified. Recall (sensitivity), precision (positive predictive value), specificity and Cohen's kappa with 95 % confidence interval were calculated. Results: Both methods identified 35 adverse events per 1000 patient days. The modified GTT method with manual review of 658 automatic triggered records identified adverse events (n = 214) in 189 records and the original GTT method identified adverse events (n = 216) in 186 records. One hundred and ten identical records were identified with adverse events by both methods. Recall, precision, specificity and reliability for records identified with adverse events were respectively 0.59, 0.58, 0.92 and 0.51 for the modified GTT method. The total manual review time in the modified GTT method was 23 h while the manual review time using the original GTT method was 411 h. Conclusions: The modified GTT method is as good as the original GTT method that complies with the GTTs aim monitoring the rate of adverse events. Resources saved by using the modified GTT method enable for increasing the sample size. The automatic trigger identification system may be developed to assess triggers in real-time to mitigate risk of adverse events.

AB - Background: Industry payments can lead to financial conflicts of interest (FCOI) among authors of clinical practice guidelines (CPGs). Guidelines for inflammatory bowel disease (IBD) may be at particularly high risk. We determined the prevalence of FCOI in IBD CPGs produced by various gastroenterology societies. Methods: We conducted a cross-sectional analysis of FCOI disclosure among CPGs related to the management of IBD. We ascertained the prevalence and types of FCOI for each guideline and determined adherence to National Academy of Medicine (NAM) standards. FCOI disclosures were compared between societies producing CPGs. Results: We identified 11 relevant CPGs with 173 total authors. There were 117 (68%) authors who declared a payment. A total of 107 (62%) authors declared FCOI related to a medication recommended in the guideline. There was a significant difference (P < 0.001) between the proportion of authors with FCOI between countries or regions. Authors of US CPGs had a significantly lower FCOI prevalence (19%) compared with other societies. Authors of UK CPGs had a significantly lower FCOI prevalence (56%) compared with Canadian (84%) and European (94%) CPGs. Three (27%) guidelines adhered to both NAM standards. Conclusions: A substantial portion of authors of IBD CPGs had FCOI. Our study found a significant difference in FCOI prevalence based on CPG sponsor nationality. Most CPGs for IBD did not adhere to NAM standards for FCOI disclosure. PMID- 30295832 TI - Prevalence of HIV indicator conditions in late presenting patients with HIV: a missed opportunity for diagnosis? AB - Objective: To evaluate prevalence of HIV indicator conditions in late-presenters with HIV infection. Design: Retrospective cohort study between 2000 and 2014. Setting: Healthcare network in Melbourne, Australia. Participants: Patients presenting with late diagnosis of HIV infection (CD4<350 cells/MUL) compared to non-late presenting patients with HIV infection. Intervention: The European AIDS Clinical Society (EACS) guidelines on HIV indicator guided testing were used to assess for any indicator conditions in their prior medical history which represented a missed opportunity for earlier diagnosis. Main outcome measures: Descriptive statistics and prevalence of HIV indicator conditions. Results: Of 436 patients with HIV infection, 82 were late presenters. Late presenters were more commonly male (83% vs 75%, p=0.11), older (mean age 45 vs 39 years), born overseas (61% vs 58%, p=0.68), and report heterosexual transmission as their exposure risk (51% vs 31%, p<0.001). Of 80 patients with late presentation of HIV infection, 54 (55%) had at least one, 29 (36%) at least two, 12 (15%) at least three and 5 (6%) had four or more previous HIV indicator conditions which would have triggered HIV testing according to guidelines. The most common indicator conditions were: unexplained loss of weight (31%), herpes zoster (10%), thrombocytopenia or leukopenia (10%), oral or oesophageal candidiasis (10%) and community acquired pneumonia (9%).Twenty-two patients (27.5%) had HIV indicator conditions diagnosed at least 12 months before the eventual diagnosis of HIV infection. Conclusion: Patients diagnosed with late-presenting HIV often had an HIV indicator condition prior to presentation, presenting a missed opportunity for earlier diagnosis. PMID- 30295833 TI - Morphological characterization of small hepatocytes after bile duct ligation in chicken. AB - Small hepatocytes have hepatocyte-like characteristics and high proliferation activity. Most small hepatocyte studies report on in vitro rat or human hepatocytes. Only a few studies of small hepatocytes after bile duct ligation have been reported, and none of these have focused on these cells in birds. In this study, small hepatocytes appearing in bile duct ligation chicken liver were examined using the morphological method with histological, immunohistochemical, and ultrastructural studies. Nine Boris Brown hens (over 744-d old) were used. In all chickens, both the common hepatoenteric duct and hepatocystic duct were ligated, and the livers were examined 1, 4, 6, 9, and 13 weeks after bile duct ligation. Histologically, the small cells were half the size of normal liver cells, and mitotic figures were often observed. The nuclei showed two forms: large and small. Many small cells were negative for periodic acid-Schiff stain, but positive cells were rarely observed. The cells existed in colonies on the side of the sinusoid of the hepatic lamina. Immunohistochemically, the small cells with large nuclei were strongly positive for CD44, albumin and proliferation cell nuclear antigen, and the cells with small nuclei were weakly positive. In the CD44-positive cell colony, negative cells were often observed to have mature hepatocyte-like morphology. Moreover, many of the cells were PAN cytokeratin negative. Ultrastructurally, the small cells had more nuclei with rich heterochromatin, poor cytoplasmic organelles, and narrow cytoplasm with a high electron density than mature hepatocytes. Moreover, cells having a middle ultrastructural characteristic existed between the small cells and mature hepatocytes. The small hepatocellular colony of the chicken appeared as a regeneration-related change in the liver after bile duct ligation. The cell had high cell proliferation activity and morphological, immunohistochemical, and ultrastructural characteristics similar to those of the mammalian small hepatocyte, as well as a similar progenitor cell.

PMID- 30295835 TI - Controller protein of restriction-modification system Kpn2I affects transcription of its gene by acting as a transcription elongation roadblock. AB - C-proteins control restriction-modification (R-M) systems' genes transcription to ensure sufficient levels of restriction endonuclease to allow protection from foreign DNA while avoiding its modification by excess methyltransferase. Here, we characterize transcription regulation in C-protein dependent R-M system Kpn2I. The Kpn2I restriction endonuclease gene is transcribed from a constitutive, weak promoter, which, atypically, is C-protein independent. Kpn2I C-protein (C.Kpn2I) binds upstream of the strong methyltransferase gene promoter and inhibits it, likely by preventing the interaction of the RNA polymerase sigma subunit with the -35 consensus element. Diminished transcription from the methyltransferase promoter increases transcription from overlapping divergent C-protein gene promoters. All known C-proteins affect transcription initiation from R-M genes promoters. Uniquely, the C.Kpn2I binding site is located within the coding region of its gene. C.Kpn2I acts as a roadblock stalling elongating RNA polymerase and decreasing production of full-length C.Kpn2I mRNA. Mathematical modeling shows that this unusual mode of regulation leads to the same dynamics of accumulation of R-M gene transcripts as observed in systems where C-proteins act at transcription initiation stage only. Bioinformatics analyses suggest that transcription regulation through binding of C.Kpn2I-like proteins within the coding regions of their genes may be widespread.

AB - Background: Mass participation events are recognized as a way of engaging low active individuals in health-enhancing physical activity, but there is a need to investigate the sustained effects on behaviour and health. This study aimed to examine changes in self-reported physical activity, weight and wellbeing over 12 months in participants of parkrun, a weekly mass participation 5 km running event. Methods: New parkrun registrants (n = 354) completed self-reported measures of physical activity, weight, happiness and stress, at registration, 6 months and 12 months. Objective data on attendance and fitness (i.e. run dates and finishing times) were obtained from the parkrun database. Results: Overall physical activity levels were high at baseline, but significantly increased over the first 6 months, before declining. By 12 months, weekly physical activity was 39 min higher than baseline. Significant reductions in body mass index were observed over 12 months, with a weight loss of 1.1% in the whole sample, and 2.4% among overweight participants. Modest increases in happiness and decreases in perceived stress were recorded. Run times suggested a 12% improvement in fitness during the study. Conclusion: Significant changes in weight, fitness and wellbeing outcomes indicate the public health benefits of regular participation in parkrun.

AB - The fraction of any surface-adsorbed contaminant available for absorption is considered the bioaccessible fraction. Applied previously to contaminants such as pesticides and heavy metals on surfaces such as soil, food and cosmetics, the term may also be used to describe the fraction of drug residue bound to work surfaces which may be mobilized via contact transfer with human skin. Police station work surfaces have been shown to commonly contain low levels of drug residues as thin films; however, no information is available on how readily these residues may be transferred to human skin during direct or glancing contact. A bioaccessibility study was undertaken in which jojoba oil and artificial sebum were used to mimic human sebum to identify how readily a mix of six licit and illicit drugs were transferred from three commonly used police station work surfaces. Transfer from surfaces was slightly greater for jojoba oil than sebum when using a direct pressure contact or a wiping motion. Generally, less than 5% of applied residues were recovered via direct contact, and up to 10% when a wiping motion was used to simulate a glancing contact. While swabbing of work surfaces with methanol provides a suitable environmental audit of drug residues present, it does not represent the bioaccessible fraction of residues available for contact transfer, and hence, absorption via skin or unintentional ingestion. The current study indicates that the ability of sebum to mobilize drug residues from thin films on work surfaces via casual contact is limited, and sebum may potentially assist in the preservation of residues on pitted work surfaces and on skin. PMID- 30295842 TI - Separation and Identification of Isomeric and Structurally Related Synthetic Cannabinoids Using 2D Liquid Chromatography and High Resolution Mass Spectrometry. AB - Novel psychoactive substances (NPS) are emerging drugs of abuse that are variations of existing compounds intended to cause a CNS psychotropic effect. Some NPS are so comparable in structure and physicochemical properties that they co-elute using traditional single column chromatographic techniques and therefore will not be detected as individual compounds. 2D liquid chromatography (2D-LC) has demonstrated applicability in difficult separations of small molecules and compounds in complex mixtures. It was hypothesized that this technique could also be used to separate co-eluting isomeric and structurally related, non-isomeric NPS, including synthetic cannabinoids (SC). Initial studies assessed several parameters, including column type, mobile phase, analysis time, gradient and flow rate, to optimize a 2D-LC method for separation and analysis of SC. The final comprehensive on-line 2D-LC method employed a Bonus-RP column in the first dimension (1D) coupled with UV detection and a biphenyl column in the second dimension (2D) coupled with QTOF-MS detection in full scan positive mode. To test the utility of the method, three SC mixes were created, each containing five compounds that were unresolvable in a traditional, 1D-LC separation; one mix with isomeric compounds and two with structurally related but non-isomeric compounds. Contour plots of UV absorbance in 1D and MS ion intensity in 2D demonstrated that all components in each mixture were successfully resolved using the 2D-LC separation method. This research serves as proof-of-concept for the application of 2D-LC to the separation of isomeric and structurally related SC. With further optimization and validation, 2D-LC may be a generally useful tool for separation of complex mixtures of NPS. PMID- 30295841 TI - Structural basis of 5' flap recognition and protein-protein interactions of human flap endonuclease 1. AB - Human flap endonuclease 1 (hFEN1) is a structure-specific nuclease essential for DNA replication and repair processes. hFEN1 has 5' flap removal activity, as well as gap endonuclease activity that is critical for restarting stalled replication forks. Here, we report the crystal structures of wild-type and mutant hFEN1 proteins in complex with DNA substrates, followed by mutagenesis studies that provide mechanistic insight into the protein-protein interactions of hFEN1. We found that in an alpha-helix forming the helical gateway of hFEN1 recognizes the 5' flap prior to its threading into the active site for cleavage. We also found that the beta-pin region is rigidified into a short helix in R192F hFEN1-DNA structures, suppressing its gap endonuclease activity and cycle-dependent kinase interactions. Our findings suggest that a single mutation at the primary methylation site can alter the function of hFEN1 and provide insight into the role of the beta-pin region in hFEN1 protein interactions that are essential for DNA replication and repair.

AB - Introduction: Hemorrhage is the leading cause of potentially preventable death on the battlefield. Hypotension in the setting of trauma portends a higher rate of mortality. We describe the interventions for trauma-related hypotension performed in the prehospital combat setting in accordance with Tactical Combat Casualty Care (TCCC) guidelines. Materials and Methods: We searched the Prehospital Trauma Registry for casualties from January 2013 to September 2014. Within that group, we searched for all casualties with documented hypotension by either measured systolic blood pressure <=90 mmHg or a weak or absent radial pulse documented by the prehospital provider. We used descriptive statistics to analyze the interventions performed in our study sample. Results: Of the 705 casualties available for query, 134 (19.0%) casualties with documented hypotension met inclusion criteria. Most casualties with hypotension had an alert mental status (70.1%), had a medical officer in their chain of care (59.0%), were Afghan (64.2%), and evacuated on an urgent status (78.4%). Explosives were the most frequent mechanism of injury (50.7%). There were 42 fluid administrations documented on 33 (24.6%) casualties. The most common fluid administered was normal saline (52.4%) followed by hetastarch solution (33.3%). There was one documented use of a fluid warmer in this cohort. One subject received four units of packed red blood cells. No other casualties had documented blood product administration. There were no documented administrations of PlasmaLyte. There were four casualties that received lactated Ringer's. Conclusion: Most casualties with documented hypotension after trauma in the Prehospital Trauma Registry did not receive prehospital blood or fluid intervention. Of the interventions performed, most did not match with contemporary TCCC guidelines. PMID- 30295845 TI - Emotional Understanding in Children with A Cochlear Implant. AB - Emotional understanding plays an important role in the physical and mental health of children. To determine whether the development of emotional understanding is delayed in children with a cochlear implant (CI), 30 children with a CI and 30 matched children with typical hearing aged between 3 and 9 years old completed three tasks (facial expression, tone expression and scene of emotion matching), in which they identified four basic emotions (happiness, sadness, anger, and fear). The participants included 40 preschool children and 20 school-aged children. Compared with the children with typical hearing, the children with a CI were significantly delayed in the ability to understand emotion; the tone expression matching task was the most difficult task for all participants; and the school-aged children performed better than the preschool children, but this trend was only observed in the typical hearing group; and happiness was the easiest emotion to identify. PMID- 30295846 TI - The Ability of a Cytomegalovirus ELISPOT Assay to Predict Outcome of Low-Level CMV Reactivation in Hematopoietic Cell Transplant Recipients. AB - Background: CMV infections in hematopoietic cell transplant (HCT) recipients cause substantial morbidity and mortality. CMV cell-mediated immunity (CMV-CMI) can be determined by levels of interferon gamma (IFN-gamma) production using an ELISPOT CMV assay (T-SPOT.CMV assay). In this study, we evaluated the ability of this assay to predict the outcome of low-level CMV reactivation in HCT recipients. Methods: We followed 55 HCT recipients with low-level CMV reactivation up to 8 weeks from enrollment. Progression to clinically significant CMV infection (CS-CMVi) was defined as a CMV viral load > 1,000 IU/ml or > 500 IU/ml in patients receiving matched related/autologous or matched unrelated transplants, respectively, and initiation of antiviral treatment. Results: Progression to CS-CMVi occurred in 31 (56%) of the HCT recipients. Spot counts of CMV-specific pp65 and IE1 antigens were significantly lower in patients who had CS-CMVi than in patients who did not. On multivariate analysis, the ELISPOT CMV responses and steroids use were the only predictors of progression to CS-CMVi. Conclusions: A strong association between low CMV-CMI and progression to CS-CMVi was observed in HCT recipients. The implementation of serial monitoring of CMV CMI may identify patients at risk of progression to CS-CMVi that require antiviral therapy. PMID- 30295847 TI - FLOWERING LOCUS T2 (FT2) regulates spike development and fertility in temperate cereals. AB - FLOWERING LOCUS T2 (FT2) is the closest paralog of the FT1 flowering gene in the temperate grasses. Here we show that overexpression of FT2 in Brachypodium distachyon and barley results in precocious flowering and reduced spikelet number, while downregulation by RNA interference results in delayed flowering and a reduced percentage of filled florets. Similarly, truncation mutations of FT2 homeologs in tetraploid wheat delayed flowering (2-4 days) and reduced fertility. The wheat ft2 mutants also showed a significant increase in the number of spikelets per spike, with a longer spike development period potentially contributing to the delayed heading time. In the wheat leaves, FT2 was expressed later than FT1, suggesting a relatively smaller role for FT2 in the initiation of the reproductive phase. FT2 transcripts were detected in the shoot apical meristem and increased during early spike development. Transverse sections of the developing spike showed the highest FT2 transcript levels in the distal part, where new spikelets are formed. Our results suggest that, in wheat, FT2 plays an important role in spike development and fertility and a limited role in the timing of the transition between the vegetative and reproductive shoot apical meristem. PMID- 30295848 TI - Validity, Reliability, and Measurement Invariance of the Diabetes Stress Questionnaire-Short Form. AB - Objective: The purpose of this study was to develop a short form of the Diabetes Stress Questionnaire (DSQ) with adequate psychometric properties (i.e., internal consistency, convergent, criterion, discriminant validity, construct validity, and measurement invariance). Methods: In total, 181 youth with type 1 diabetes (T1D) completed the 65-item DSQ, and archival data were obtained from 142 youth with T1D to serve as an independent cross-validation sample. Twenty-four items were chosen to retain the original eight scales of the DSQ and to maximize internal consistency and correlations to full subscales. Confirmatory factor analyses were used to evaluate the proposed factor structure of the Diabetes Stress Questionnaire-Short Form (DSQ-SF) and to assess invariance of the DSQ-SF across sex, race, grade level, glycemic control, illness duration, and annual income categories. Results: The 24-item DSQ-SF was found to have good internal consistency, factor structure and fit, correlated highly to the full scale (r = .98), and was invariant across sex, race, grade level (<9th grade or >9th grade), glycemic control, illness duration, and annual income. Conclusions: The DSQ-SF appears to be a psychometrically robust measure of diabetes-specific stress in youth with T1D. Present findings suggest that the DSQ-SF has the potential to be a useful, quick, cost-effective, and comprehensive screening tool for identifying youth with T1D who may benefit from T1D-specific stress reduction interventions as a way to improve health behaviors, psychosocial well-being, and glycemic control. PMID- 30295849 TI - Simultaneous Detection and Quantification of Three Novel Prescription Drugs of Abuse (Suvorexant, Lorcaserin and Brivaracetam) in Human Plasma by UPLC-MS-MS. AB - Suvorexant (SVR), lorcaserin (LCR) and brivaracetam (BVR) have been recently approved for the treatment of insomnia, obesity and epilepsy, respectively. Despite their clinical uses, these drugs have some abuse potential and have been enlisted under the schedule IV (SVR, LVR) and schedule V (BVR) categories of the Controlled Substances Act. A sensitive UPLC-MS-MS assay was developed for simultaneously determining SVR, LCR and BVR in human plasma. The liquid-liquid extraction method, using tert-butyl methyl ether as an extracting solvent, was used for sample preparation. Chromatographic separation was performed by using the Acquity BEH C18 column, using 10 mM ammonium acetate/acetonitrile/formic acid (15/85/0.1%; v/v/v) as the mobile phase. For sample ionization, electrospray ionization was used in the positive-ion mode. The multiple-reaction monitoring mode was used for detecting and quantifying analytes by using separate precursor to-product ion transitions. The assay was validated following the SWGTOX guidelines, and all validation results were within the acceptable limits. The calibration curves of the analytes in the plasma were found to be linear, and the coefficient of determination (R2) was >= 0.992 for all the three analytes. The limit of detection values for SVR, LCR and BVR were 0.08, 0.11 and 0.26 ng/mL, respectively, whereas the limit of quantification values were 0.16, 0.27 and 0.65 ng/mL, respectively. The assay developed in this study is suitable for the identification and quantification of SVR, LCR and BVR in the forensic laboratory.

AB - The molecular mechanism in pancreatic beta cells underlying hyperlipidemia and insulin insufficiency remains unclear. Here, we find that the fatty acid-induced decrease in insulin levels occurs due to a decrease in insulin translation. Since regulation at the translational level is generally mediated through RNA-binding proteins, using RNA antisense purification coupled with mass spectrometry, we identify a novel insulin mRNA-binding protein, namely, DDX1, that is sensitive to palmitate treatment. Notably, the knockdown or overexpression of DDX1 affects insulin translation, and the knockdown of DDX1 eliminates the palmitate-induced repression of insulin translation. Molecular mechanism studies show that palmitate treatment causes DDX1 phosphorylation at S295 and dissociates DDX1 from insulin mRNA, thereby leading to the suppression of insulin translation. In addition, DDX1 may interact with the translation initiation factors eIF3A and eIF4B to regulate translation. In high-fat diet mice, the inhibition of insulin translation happens at an early prediabetic stage before the elevation of glucose levels. We speculate that the DDX1-mediated repression of insulin translation worsens the situation of insulin resistance and contributes to the elevation of blood glucose levels in obese animals. PMID- 30295851 TI - The jPOST environment: an integrated proteomics data repository and database. AB - Rapid progress is being made in mass spectrometry (MS)-based proteomics, yielding an increasing number of larger datasets with higher quality and higher throughput. To integrate proteomics datasets generated from various projects and institutions, we launched a project named jPOST (Japan ProteOme STandard Repository/Database, https://jpostdb.org/) in 2015. Its proteomics data repository, jPOSTrepo, began operations in 2016 and has accepted more than 10 TB of MS-based proteomics datasets in the past two years. In addition, we have developed a new proteomics database named jPOSTdb in which the published raw datasets in jPOSTrepo are reanalyzed using standardized protocol. jPOSTdb provides viewers showing the frequency of detected post-translational modifications, the co-occurrence of phosphorylation sites on a peptide and peptide sharing among proteoforms. jPOSTdb also provides basic statistical analysis tools to compare proteomics datasets. PMID- 30295852 TI - CREG1 promotes uncoupling protein 1 expression and brown adipogenesis in vitro. AB - Brown adipocytes play a critical role for adaptive thermogenesis to regulate body temperature in cold or to circumvent diet-induced obesity. In the present study, we investigated the role of cellular repressor of E1A-stimulated genes 1 (CREG1) on brown adipogenesis and uncoupling protein 1 (UCP1) expression by using in vitro culture models. In murine mesenchymal stem cell line C3H10T1/2, Creg1 mRNA expression significantly increased in a time-dependent manner along with Ucp1 mRNA induction in brown adipogenesis. Creg1 gene overexpression upregulated the expression of brown fat-related genes including Ucp1 but its suppression downregulated these gene expression in C3H10T1/2 cells. Unlike the brown adipogenesis, Creg1 mRNA expression decreased significantly after differentiation stimulation in white adipogenesis of 3T3-L1 cells. Either Creg1 gene overexpression or suppression hardly affected white adipogenesis. In addition, CREG1 protein stimulated brown adipogenesis and rescued the adipogenesis in the absence of thyroid hormone in C3H10T1/2 cells. In reporter assay, CREG1 induction stimulated Ucp1 promoter activity, which was enhanced by co-expression with thyroid hormone receptors. The effect of CREG1 on Ucp1 promoter activity was also stimulated by retinoic acid. These results strongly suggest that CREG1 plays an important role on the regulation of UCP1 expression and brown adipogenesis.

AB - A new sterile insect technique (SIT) program is currently being developed for management of the Queensland fruit fly, Bactrocera tryoni (Froggatt) (Diptera: Tephritidae), the most costly challenge to Australian horticulture in the eastern states. SIT relies on cost-effective mass production of millions of high-quality flies. A recently developed gel larval diet has proven effective, enabling production of large numbers of high-quality flies, but includes some costly ingredients. With a basic diet now available, current research focuses on refining the formulation to deliver a more economical diet. Wheat germ oil (WGO) is the main lipid source in the current Queensland fruit fly gel diet, but is a particularly expensive ingredient and has limited availability. To identify an oil that maintains high productivity and fly quality at reduced cost, the present study assessed production and performance of Queensland fruit flies reared on gel larval diets containing the WGO that was used in previous studies (WGO/M), an alternative WGO (WGO/A), sunflower oil, rice bran oil, and canola oil. Diets containing canola oil ($5.24/liter) performed as well as diets with WGO/M ($116/liter) in terms of parental egg hatch, pupal number, pupal weight, adult emergence, percentage and rate of fliers, sex ratio, fecundity, and fertility (F1 egg hatch), offering a remarkably cost-effective alternative. Costs of oil in Queensland fruit fly production are reduced by ca. 95% per 1,000 flight capable adults ('fliers'). Substantial savings may be made in Queensland fruit fly mass rearing by substituting WGO/M with canola oil in gel larval diets without compromising productivity.

PMID- 30295857 TI - Management decision of hospital surge: assessing seasonal upsurge in inpatient medical bed occupancy rate among public acute hospitals in Hong Kong. AB - Background: There were recurrent upsurges in demand for public hospital services in Hong Kong. An understanding of the contribution of some possible factors for the rise in health care burden would help to inform hospital management strategies. Aim: To evaluate the utilisation patterns of hospitalizations in medical wards among public acute hospitals in Hong Kong during surge periods. Design: Retrospective study. Methods: By extracting the information in press releases between 2014 and 2018, descriptive statistics about medical ward occupancy situation during six surge periods were generated. A time series model was constructed to estimate the occupancy rate at each hospital and assess its relationship with the intensity of seasonal influenza activity, extreme weather, day of week and long holidays. Results: There was a significant increase in the number of admissions to medical wards in all six surge periods. A significant variation in occupancy rate between weekdays and geographic regions was observed. The occupancy rate in 10, out of 15, hospitals was significantly associated with the influenza activity, while there was limited effect of weather on the occupancy rate. A significant holiday effect was observed during Christmas and Chinese New Year, resulting in a lower bed occupancy rate. Conclusions: A differential burden in public hospitals during surge periods was reported. Contingency bed and staff management shall be tailored to individual hospitals, given their differences in the determinants for inpatient bed occupancy. PMID- 30295858 TI - A Gas Chromatography-Triple Quadrupole Mass Spectrometry Assay for the Quantification of Opiates in Human Blood Samples. AB - A simplified protein precipitation method in combination with gas chromatography triple quadrupole mass spectrometry (GC-MS-MS) analysis was developed and validated for the simultaneous determination of codeine, morphine, 6 acetylmorphine (6-MAM), hydrocodone and hydromorphone in human blood samples. A protein precipitation with 10% trichloroacetic acid followed by solid-phase extraction using a mixed-mode cartridge was used to separate the analyte from the blood samples. A BSTFA + 1% TMCS was used for derivatization of opiates prior to the analysis. Codeine-D3, morphine-D3, 6-acetylmorphine-D3 and hydrocodone-D6 were used as internal standards. The GC-MS-MS was operated under multiple reaction monitoring mode using electron ionization technique. The transition ions used for quantitation were 371 -> 234 for codeine, 429 -> 146 for morphine, 399 > 287 for 6-MAM, 299 -> 228 for hydrocodone and 357 -> 314 for hydromorphone. The method was linear over the concentration range 2.5-1000 ng/mL for all analytes, except hydrocodone which was linear over 5-1000 ng/mL with a correlation coefficient (r2) = 0.99. The limit of detection was 1.0 ng/mL for all compounds except hydrocodone which was 2.5 ng/mL. The limit of quantitation was 2.5 ng/mL for all compounds except hydrocodone which was 5.0 ng/mL. The precision (% RSD) was within 1.26-14.81 and the accuracy (% Bias) was within -6.29-10.93% for all compounds. The method successfully analyzed morphine (305 ng/mL) and 6 acetylmorphine (6-MAM) (2.3 ng/mL) in a human blood sample received from an opiate user.

AB - Field populations of thrips (Scirtothrips dorsalis Hood) from citrus nurseries and psyllids (Diaphorina citri Kuwayama) from commercial citrus orchards of three districts in Maharashtra State in India were evaluated for levels of resistance to organophosphates (acephate, chlorpyrifos, quinalphos, and dimethoate), neonicotinoids (thiamethoxam, imidacloprid), abamectin and spinosad between 2012 and 2017. Leaf dip bioassays for thrips and shoot tip bioassay for nymph and adult psyllids were used to assess levels of insecticide resistance as indicated by resistance ratios (RRs). In general, levels of insecticide resistance were zero (RR = 1) or very low (RR = 2-10); however, we recorded 21.0- and 28.0-fold increase in resistance (RR = 21-50) to spinosad 45SC in S. dorsalis between 2016 and 2017 that may be attributed to the continuous application of the insecticide for the management of various sucking insect pests of citrus. We found that levels of resistance to insecticides in adult and nymph D. citri collected from the three districts were zero to low (RR = 2-10). Our data show there may be a shift in resistance to neonicotinoid insecticides that are widely used among citrus growers in the study region. Results from this study indicate that the evolution of insecticide resistance and cross-resistance may be decelerated by the rotational use of insecticides with different modes of action. PMID- 30295862 TI - The G-matrix Simulator Family: Software for Research and Teaching. AB - Genetic variation plays a fundamental role in all models of evolution. For phenotypes composed of multiple quantitative traits, genetic variation is best quantified as additive genetic variances and covariances, as these values determine the rate and trajectory of evolution. Additive genetic variances and covariances are often summarized conveniently in the G-matrix, which has additive genetic variances for each trait on the diagonal and additive genetic covariances as its off-diagonal elements. The evolution of the G-matrix is an interesting topic in its own right, because the processes that affect trait means also affect the distribution of standing genetic variation, which, in turn, feeds back to affect the rate of change of trait means. Theoretical studies of the G-matrix have profitably employed simulation-based models because the topic is often too complex to yield meaningful analytical results. Here, we present a series of G matrix simulation software packages, which have emerged from about 15 years of research on this topic. These simulation models are useful for research and for building intuition regarding the evolution of the G-matrix under a wide variety of circumstances. A tutorial and source code also provide a foundation upon which future models can be built. These tools will be useful to students as well as researchers.

AB - Objectives: Volunteering is associated with improved physical and psychological well-being; volunteers feeling more respect for their work may have better well being than their counterparts. Method: This study investigated the effects of felt respect for volunteer work on volunteering retention, daily affect, well being (subjective, psychological, and social), and mortality. The study analyzed survey and mortality data from a national sample of 2,677 volunteers from the Midlife in the United States Study over a 20-year span. Daily affect data were obtained from a sub-sample of 1,032 volunteers. Results: Compared to volunteers feeling less respect from others, those feeling more respect (a) were more likely to continue volunteering 10 and 20 years later, (b) had higher levels of daily positive affect and lower levels of daily negative affect, and (c) had higher levels of well-being over a 20-year period. The effect of felt respect on mortality was not statistically significant. Discussion: Greater level of felt respect for volunteer work is positively related to volunteers' retention rates, daily affective experience, and well-being. PMID- 30295864 TI - BIGGER ORGANS and ELEPHANT EAR-LIKE LEAF1 control organ size and floral organ internal asymmetry in pea (Pisum sativum L.). AB - Control of organ size and shape by cell proliferation and cell expansion is a fundamental process during plant development, but the molecular mechanisms that set the final size and shape of determinate organs in plants remain unclear, especially in legumes. In this study, we characterized several mutants including bigger organs (bio) and elephant-ear-like leaf 1 (ele1) in pea that displayed similar phenotypes, with the enlarged leaves and symmetrical lateral and ventral petals. Genetic analysis showed that BIO interacted with specific regulators SYMMETRICAL PETAL1 (SYP1) and SYP5 to control floral organ internal (IN) asymmetry in pea. Using a comparative approach, we cloned BIO and ELE1, revealing that they encode a KIX domain protein and an ortholog of Arabidopsis PEAPOD (PPD), respectively. Furthermore, genetic analysis, physical interaction assays and gene expression analysis showed that BIO and ELE1 physically interact with each other and with the transcription factor LATHYROIDES (LATH) to repress expression of downstream genes such as GROWTH-REGULATING-FACTOR 5. Our data suggested that the BIO-ELE1 module in legumes plays a key role to regulate organ development so as to create distinct final forms with characteristic size and shape.

PMID- 30295868 TI - Acetoin and 2,3-butanediol from Bacillus amyloliquefaciens induce stomatal closure in Arabidopsis thaliana and Nicotiana benthamiana. AB - Plants live in close association with large communities of microbes, some of which are foliar pathogens that invade tissues, primarily via stomata on the leaf surface. Stomata are considered part of an integral, innate immunity system capable of efficiently preventing pathogens from entering the host plant. Although Bacillus, a typical plant growth-promoting rhizobacterium, is known to induce stomatal closure, the substances participating in this closure and the mechanism involved in its regulation remain poorly understood. Here, we screened a mutant library and conducted site-specific mutagenesis experiments in order to identify such substances. We found that acetoin and 2,3-butanediol from B. amyloliquefaciens FZB42 induced stomatal closure in Arabidopsis thaliana and Nicotiana benthamiana. These two components could function either via root absorption or volatilization to restrict stomatal apertures, but root absorption was more efficient. Both substances invoked the salicylic acid and abscisic acid signaling pathways to close the stomata and stimulated accumulation of hydrogen peroxide and nitric oxide. The results present comprehensive evidence of how soil rhizobacteria may affect plant stomata, in a way that reinforces the evolved mutualism between the two groups of organisms, and provide potential alternative avenues of research towards reducing the incidence of disease in crops.

AB - Background: The genetic background of patients with hemoglobin (Hb) H disease in Taiwan has been investigated; however, the clinical features and treatment outcomes were not reported. Objective: To analyze the clinical features and genotypes of patients with HbH who reside in Taiwan. Methods: We conducted a retrospective analysis of the clinical and molecular characteristics of 38 patients with HbH disease who were undergoing treatment at Kaohsiung Medical University Hospital, Taiwan. Results: Initial Hb levels were lower and the numbers of patients requiring iron-chelation therapy were higher in the nondeletional HbH group than in the deletional HbH group (P <.05). Compared with the healthy population, the patients with HbH disease exhibited short body length, low body weight, and low body mass index (BMI). Conclusions: Patients with nondeletional HbH disease had lower Hb levels and a higher requirement for splenectomy and iron-chelation therapy than did those with deletional HbH disease. Also, growth status was compromised in patients with HbH disease. PMID- 30295866 TI - Understanding the Factors That Shape Patterns of Nucleotide Diversity in the House Mouse Genome. AB - A major goal of population genetics has been to determine the extent by which selection at linked sites influences patterns of neutral nucleotide diversity in the genome. Multiple lines of evidence suggest that diversity is influenced by both positive and negative selection. For example, in many species there are troughs in diversity surrounding functional genomic elements, consistent with the action of either background selection (BGS) or selective sweeps. In this study, we investigated the causes of the diversity troughs that are observed in the wild house mouse genome. Using the unfolded site frequency spectrum, we estimated the strength and frequencies of deleterious and advantageous mutations occurring in different functional elements in the genome. We then used these estimates to parameterize forward-in-time simulations of chromosomes, using realistic distributions of functional elements and recombination rate variation in order to determine whether selection at linked sites can explain the observed patterns of nucleotide diversity. The simulations suggest that BGS alone cannot explain the dips in diversity around either exons or conserved noncoding elements. A combination of BGS and selective sweeps produces deeper dips in diversity than BGS alone, but the inferred parameters of selection cannot fully explain the patterns observed in the genome. Our results provide evidence of sweeps shaping patterns of nucleotide diversity across the mouse genome and also suggest that infrequent, strongly advantageous mutations play an important role in this. The limitations of using the unfolded site frequency spectrum for inferring the frequency and effects of advantageous mutations are discussed. PMID- 30295869 TI - Who can decide? Prevalence of mental incapacity for treatment decisions in medical and surgical hospital inpatients in Ireland. AB - Background: The prevalence of mental incapacity for treatment decisions among medical and surgical hospital inpatients is poorly understood or not known in many countries, including Ireland. Aim: To assess the prevalence of mental incapacity in hospital inpatients in Ireland. Design: Cross-sectional observational study of mental incapacity for treatment decisions. Methods: We assessed mental capacity in 300 randomly selected hospital inpatients in 2 general hospitals in Dublin (urban) and Portlaoise (rural), in Ireland, using the MacArthur Competence Assessment Tool for Treatment (MacCAT-T). Results: Mean MacCAT-T score was 14.80 (SD: 8.40) out of a possible maximum of 20 (with a higher score indicating greater mental capacity). Over one quarter of participants (27.7%; n = 83) lacked the mental capacity for treatment decisions; 1.7% (n = 5) had partial capacity and 70.7% (n = 212) had full capacity. Scores for each of the four sub-scales of the MacCAT-T were generally consistent across the four key areas of understanding, appreciation, reasoning and expressing a choice. Conclusions: Mental incapacity for treatment decisions is common in medical and surgical hospital inpatients in Ireland. This issue both merits and requires greater attention in clinical practice, research and legislation.

AB - BACKGROUND: The optimal management of unruptured brain arteriovenous malformations (AVMs) is controversial after the ARUBA trial. OBJECTIVE: To confirm or repudiate the ARUBA conclusion that "medical management only is superior to medical management with interventional therapy for unruptured brain arteriovenous malformations." METHODS: Data were collected from 1351 patients treated with Gamma Knife Surgery (GKS; Elekta AB, Stockholm, Sweden) for unruptured and untreated AVMs The follow-up was 8817 yr (median 5.0 and mean 6.5). The results of the analyses were compared to that found in patients randomized to medical management only in the ARUBA trial and extrapolated to a 10 yr time period. Our data were also compared to the natural course in a virtual AVM population for a 25-yr time period. RESULTS: The incidence of stroke was similar among ARUBA and our patients for the first 5 yr. Thereafter, the longer the follow-up, the relatively better outcome following treatment. Both the mortality rate and the incidence of permanent deficits in patients with small AVMs were the same as in untreated patients for the first 2 to 3 yr after GKS, after which GKS patients did better. Patients with large AVMs had a higher incidence of neurological deficits in the first 3 yr following GKS. The difference decreased thereafter, but the time until break even depended on the analysis method used and the assumed risk for hemorrhage in patent AVMs. CONCLUSION: The ARUBA trial conclusion that medical management is superior to medical management with interventional therapy for all unruptured AVMs could be repudiated.

AB - Recent high throughput experimental methods have been used to collect large biomedical omics datasets. Clustering of single omic datasets has proven invaluable for biological and medical research. The decreasing cost and development of additional high throughput methods now enable measurement of multi omic data. Clustering multi-omic data has the potential to reveal further systems level insights, but raises computational and biological challenges. Here, we review algorithms for multi-omics clustering, and discuss key issues in applying these algorithms. Our review covers methods developed specifically for omic data as well as generic multi-view methods developed in the machine learning community for joint clustering of multiple data types. In addition, using cancer data from TCGA, we perform an extensive benchmark spanning ten different cancer types, providing the first systematic comparison of leading multi-omics and multi-view clustering algorithms. The results highlight key issues regarding the use of single- versus multi-omics, the choice of clustering strategy, the power of generic multi-view methods and the use of approximated p-values for gauging solution quality. Due to the growing use of multi-omics data, we expect these issues to be important for future progress in the field. PMID- 30295873 TI - A supercomplex, approximately 720 kDa and composed of both photosystem reaction centers, dissipates excess energy by PSI in green macroalgae under salt stress. AB - The thylakoid membranes of plants play a critical role in electron transfer and energy fixation, and are highly dynamic. So far, studies on the thylakoid membranes have mainly focused on microalgae and higher plants, yet very little information is available on the macroalgal thylakoids. Here, we studied the structure and organization of the thylakoid membranes in Ulva prolifera, a representative species of the green macroalgae. We found U. prolifera had few but long loosely-stacked membranes which lack the conventional grana found in higher plants. However, the thylakoid membrane complexes demonstrate lateral heterogeneity. Moreover, we found a supercomplex composed of Photosystem II (PSII), light-harvesting complex II (LHCII) and Photosystem I (PSI) from U. prolifera under salt stress. The supercomplex is approximately 720 kDa, and includes the two important photoprotection proteins Photosystem II S subunit (PsbS) and the light-harvesting complex stress-related protein (LhcSR), as well as xanthophyll cycle pigments (violaxanthin, antheraxanthin and zeaxanthin). Time resolved fluorescence analysis suggested that, in the supercomplex, excitation energy could efficiently be transferred from PSII to PSI, even when PSII was inhibited, a function which disappeared when the supercomplex was incubated in mild detergent. We suggest that the supercomplex might be an important mechanism to dissipate excess energy by PSI in green macroalgae under salt stress.

AB - Introduction: The purpose of this study was to examine Uniformed Services University (USU) women graduates in terms of percent of graduates', specialty choices and practice choices as compared to civilian women who graduate and practice medicine in the USA. This is a perspective that is currently not well understood. Materials and Methods: We conducted a retrospective cohort study of all USU women graduates (1980-2015) using the 2016 American Medical Association (AMA) Physician Masterfile that included data from the American Board of Medical Specialties (ABMS). To describe USU women graduates' current practice status we queried for: (1) medical school; (2) year of graduation; (3) practice state; (4) primary specialty board; and (5) major professional activity (office-based practice vs. full-time hospital staff). Data were analyzed using descriptive statistics. Results: Our findings indicate that the percentage of USU women graduates has increased over time and stands at 29% for the 2010-2015 cohort as compared to 48% for women graduating from all U.S. medical schools. USU women graduates have a slightly higher board certification rate (89%) than the national cohort (88%). USU women graduates also have a higher percentage in family medicine (19%) than the national cohort (14%). USU women graduates practice in 48 states and were equally split between full-time hospital staff and office-based practice which differs from the national cohort that has a much higher proportion in office-based practice (85%). Conclusions: Women are making significant gains in enrollment at USU, obtaining board certification at similar, and in some cases, higher rates than their civilian peers, and practicing in diverse specialties. This study provides a descriptive picture of women's enrollment and practice characteristics from a military-based medical school. Future work could examine underlying factors that may influence their school choice, career experiences, and trajectories. Future research could also focus on women's experiences of mentoring and support to better understand these factors.

PMID- 30295876 TI - PIKfyve accelerates phagosome acidification through activation of TRPML1 while arrests aberrant vacuolation independent of the Ca2+ channel. AB - PIKfyve phosphorylates PtdIns(3)P to PtdIns(3,5)P2. One of the best characterized effector downstream of PtdIns(3,5)P2 is a lysosomal Ca2+ channel, TRPML1. Although it has been reported that TRPML1 is involved in phagosome-lysosome fusion, the relevance of the Ca2+ channel in phagosome acidification has been denied. In this paper, however, we demonstrated that the phagosome acidification was dependent on TRPML1. Based on the classical idea that FITC-fluorescence is highly sensitive to acidic pH, we could estimate the phagosome acidification by time laps imaging. FITC-zymosan fluorescence that was engulfed by macrophages, decreased immediately after the uptake while the extinction of FITC-zymosan fluorescence was delayed in PIKfyve-deficient cells. The acidification arrest was completely rescued in the presence of Ca2+ ionophore A23187. Cells treated with a PIKfyve inhibitor, apilimod, also showed delayed phagosome acidification but were rescued by the overexpression of TRPML1. Additionally, TRPML1 agonist, ML-SA1 was effective to acidify the phagosome in PIKfyve-deficient cells. Another phenotype observed in PIKfyve-deficient cells is vacuole formation. Unexpectedly, enlarged vacuole formation in PIKfyve-deficient cells was not rescued by Ca2+ or over expression of TRPML1. It is likely that the acidification and vacuolation arrest is bifurcating downstream of PIKfyve.

A primary CPA location of an ependymoma is distinctly uncommon. In this 3-dimensional video, we present a 38-yr-old woman with a 1-mo history of vertigo and slow left sided gaze drift. She underwent microsurgical gross total resection of the CPA ependymoma via retrosigmoid approach. The histopathology was grade III anaplastic ependymoma. She tolerated the surgery well and her postoperative course was uneventful. She received radiation therapy and there was no recurrent disease in follow-up studies. Important steps of the surgical approach and microsurgical techniques in resection of these challenging tumors are demonstrated in this 3-dimensional surgical video.

AB - Fungal infections are a major cause of skin and mucosal membrane disease. Immunocompromised individuals, such as those undergoing chemotherapy, are most susceptible to fungal infections. With a growing population of immunocompromised patients, there are many reports of increasing numbers of infections and of fungal strains resistant to current antifungals. One way to treat drug-resistant infections is to administer combinations of drugs to patients. Azoles are the most prescribed antifungals, as they are broad-spectrum and orally bioavailable. Terfenadine (TERF) and ebastine (EBA) are second-generation antihistamines, with EBA being used in many countries. In this study, we explored combinations of seven azole antifungals and two antihistamines (TERF and EBA) against a panel of 13 Candida fungal strains. We found 55 out of 91 combinations tested of TERF and EBA against the various fungal strains to be synergistic with the azoles. To evaluate the efficiency of these combinations to inhibit fungal growth, we performed time-kill assays. We also investigated the ability of these combinations to disrupt biofilm formation. Finally, we tested the specificity of the combinations towards fungal cells by mammalian cytotoxicity assays. These findings suggest a potential new strategy for targeting drug-resistant Candida infections. PMID- 30295882 TI - Resection of an Embolized Cirsoid Aneurysm With Intracranial Venous Drainage: 2 Dimensional Operative Video. AB - Cirsoid aneurysms, also known as scalp arteriovenous malformations (AVM), are rare congenital extracranial vascular anomalies that often present as an enlarging pulsatile scalp mass. A 14-yr-old male presented with a pulsatile scalp lesion that was first noticed 3 yr prior and had progressively enlarged. No history of trauma was reported. MRI demonstrated a 4 cm wide and 2 cm tall nidus and catheter angiography was performed to further define the vascular supply and drainage. The patient underwent transvenous endovascular embolization followed by surgical excision via a bicoronal incision, as shown in this operative video. Care was taken to identify, cauterize, and transect feeding vessels from the superficial temporal, supratrochlear, and supraorbital arteries circumferentially to completely devascularize and resect the galeal nidus from overlying scalp tissue and underlying pericranium. Previously unreported in the literature, transosseous emissary veins partially draining the lesion were noted on angiography and were waxed thoroughly during surgery. Six-month follow-up examination demonstrated a well-healed incision without evidence of AVM recurrence. The unique venous drainage of this cirsoid aneurysm highlights the value of diagnostic angiography to fully characterize these rare and complex vascular lesions prior to pursuing definitive treatment. IRB approval was obtained from the Ann & Robert H. Lurie Children's Hospital of Chicago Institutional Review Board (IRB #2018-1799). The IRB waives the requirement of obtaining informed consent for this study in accordance with 45 CFR 46.116(d). PMID- 30295883 TI - Cost and Healthcare Utilization Among Non-Elderly Head and Neck Cancer Patients in the Military Health System, a Single-Payer Universal Health Care Model. AB - Introduction: Examining costs and utilization in a single-payer universal health care system provides information on fiscal and resource burdens associated with head and neck cancer (HNC). Here, we examine trends in the Department of Defense (DoD) HNC population with respect to: (1) reimbursed annual costs and (2) patterns and predictors of health care utilization in military only, civilian only, and both systems of care (mixed model). Materials and Methods: A retrospective, cross-sectional study was conducted using TRICARE claims data from fiscal years 2007 through 2014 for reimbursement of ambulatory, inpatient, and pharmacy charges. The study was approved by the Defense Health Agency Office of Privacy and Civil Liberties as exempt from institutional review board full review. The population was all beneficiaries, age 18-64, with a primary ICD-9 diagnosis of HNC, on average, 2,944 HNC cases per year. The outcomes of regression models were total reimbursed health care cost, and counts of ambulatory visits, hospitalizations, and bed days. The predictors were fiscal year, demographic variables, hospice use, type and geographic region of TRICARE enrollment, use of military or civilian care or mixed use, cancer treatment modalities, the number of physical and mental health comorbid conditions, and tobacco use. A priori, null hypotheses were assumed. Results: Per annual average, 61% of the HNC population was age 55-64, and 69% were males. About 6% accessed military facilities only for all health care, 60% accessed civilian only, and 34% accessed both military and civilian facilities. Patients who only accessed military care had earlier stage disease as indicated by rates of single modality treatment and hospice use; military care only and mixed use had similar rates of combination treatment and hospice use. The average cost per patient per year was $14,050 for civilian care only, $13,036 for military care only, and $29,338 for mixed use of both systems. The strongest predictors of higher cost were chemotherapy, radiation therapy, head and neck surgery, hospice care, and mixed use care. The strongest predictors of health care utilization were chemotherapy, use of hospice, the number of physical and mental health comorbidities, radiation therapy, head and neck surgery, and system of care. Conclusions: To a single payer, the use of a single system of care exclusively among HNC patients is more cost-effective than use of a mixed-use system. The results suggest an over utilization of ambulatory care services when both military and civilian care are accessed. Further investigation is needed to assess coordination between systems of care and improved efficiencies with respect to the cost and apparent over utilization of health care services. PMID- 30295884 TI - Needlestick injuries among Malaysian healthcare workers. AB - Background: Needlestick injury (NSI) is a significant occupational health issue among healthcare workers (HCWs). Aims: To determine the national self-reported incidence and risk factors for NSI among Malaysian Ministry of Health (MOH) HCWs. Methods: Using data from the MOH national sharps injury surveillance programme, information on reported NSIs over a 1-year period (2016) for different HCW subgroups were extracted and analysed. Results: A total of 1234 NSI cases were reported in 2016, giving an overall incidence of 6 injuries per 1000 HCWs. Medical doctors recorded the highest incidence (21.1 per 1000 HCWs) followed by dental staff (7.5), pharmacy staff (4.2), nurses (3.7), medical assistants (3.4) and allied and auxiliary staff (1.0). Doctors had significantly increased risk of NSI compared with allied and auxiliary staff (relative risk [RR] = 20.7, 95% confidence interval [CI] 15.5-27.5), medical assistants (RR = 6.1, 95% CI 4.5 8.2), nurses (RR = 5.7, 95% CI 5.0-6.6), pharmacy staff (RR = 5.0, 95% CI 3.7 6.6) and dental staff (RR = 2.8, 95% CI 2.2-3.5). Significant differences were found in age and sharps- handling experience between occupational subgroups (P < 0.001 for both variables). Male employees had higher risk than females (RR = 1.33, 95% CI 1.18-1.50), with a significant difference seen in their sharps handling experience (P < 0.01). Important risk factors included unsafe practices such as recapping of needles and their improper disposal. Conclusions: The national incidence of NSI amongst Malaysian HCWs was lower compared with other countries, but unsafe practices remain an important concern. There is a need to formulate, implement and monitor safe and consistent practices for the different healthcare professionals. PMID- 30295885 TI - Measles immunity in an Italian teaching hospital. AB - Background: Healthcare workers (HCWs) have an increased exposure risk to measles, which can put them, their patients and their relatives at risk of infection. In Italy, 4617 cases of measles were reported in 2017; 302 involving HCWs. According to the Italian National Immunization and Prevention Plan, all HCWs should have demonstrable evidence of immunity to measles. Aims: To evaluate measles immunization status in HCWs at a large Italian teaching hospital. Methods: We analysed clinical records and measles-specific IgG antibody titres of HCWs undergoing occupational health surveillance between 1 January and 31 August 2017. Results: Among the 1532 HCWs (mean age 32.7 +/- 10.4 years) included in the study, 87% (1328) had protective antibody titres. The proportion of protective titres was highest in those born before 1982. No significant gender differences in mean measles-specific IgG antibody titres were detected. Conclusions: Our study shows non-protective measles IgG antibody titres in a substantial percentage of HCWs, especially those born in the 1980s and 1990s. Due to the increased risk of measles transmission in the hospital environment, increased prevention strategies are required, including rigorous screening and prompt vaccination of non-immune workers. PMID- 30295886 TI - The spatiotemporal deposition of lysophosphatidylcholine within starch granules of maize endosperm and its relationships to the expression of genes involved in endoplasmic reticulum-amyloplast lipid trafficking and galactolipid synthesis. AB - The presence of lipids within starch granules is specific to cereal endosperm starches. These starch lipids are composed of lysophospholipids, especially lysophosphatidylcholine (LysoPC) and free fatty acids that strongly impact the assembly and properties of cereal starches. However, the molecular mechanisms associated with this specific lipid routing have never been investigated. In this study, MALDI mass spectrometry imaging revealed decreasing gradients in starch LysoPC concentrations from the periphery to the center of developing maize endosperms. This spatiotemporal deposition of starch LysoPC was similar to the one previously observed for ER-synthesized storage proteins, i.e., zeins, suggesting that LysoPC might originate in the ER, as already reported for chloroplasts. Furthermore, a decrease of the palmitate concentration of amyloplast galactolipids was observed during endosperm development, correlated with the preferential trapping of palmitoyl-LysoPC by starch carbohydrates, suggesting a link between LysoPC and galactolipid synthesis. Using microarray, the homologous genes of the Arabidopsis ER-chloroplast lipid trafficking and galactolipid synthesis pathways were also expressed in maize endosperm. These strong similarities suggest that the encoded enzymes and transporters are adapted to managing the differences between chloroplast and amyloplast lipid homeostasis. Altogether, our results led us to propose a model where ER-amyloplast lipid trafficking directs the LysoPC towards one of two routes, the first towards the stroma and starch granules and the other towards galactolipid synthesis.

PMID- 30295889 TI - Microsurgery of Spinal Dural Arteriovenous Fistula Using Indocyanine Green Video Angiography: 2-Dimensional Operative Video. AB - Spinal dural arteriovenous fistulas (SDAVF) develop by direct abnormal arteriovenous connection between both sides of the spinal dura matter. In this condition, there is no intervening nidus between a meningeal segmental artery and a radiculomedullary vein. Open microsurgery is one of the choices for patients with SDAVF. When the AVF is on the inner dural surface, we can easily block the radiculomedullary vein in a microscopic view. We herein report a 50-yr-old woman who presented with low back pain, was diagnosed with an SDAVF, and underwent surgical treatment under a microscopic view. The spinal angiography demonstrated abnormal arteriovenous connections between intercostal arteries at the level of Th11 to 12 and the intradural radiculomedullary vein. Operative indocyanine green (ICG) microangiography demonstrated the blood flow in meningeal vessels and their anastomoses between both sides of the dural surface. We easily identified the radiculomedullary vein fed by the surrounding meningeal feeding arteries and block completely under a direct microscopic view. We detected the change in hemodynamic during feeder ligation by Flow 800 (Zeiss Penteto Flow 800 microscope; Zeiss Corporation, Tokyo, Japan). After surgery, the patient's symptoms disappeared and no recurrence of the disease has been noted in the past 23 mo. We have received the informed consent of this patient for the publication of this case report. PMID- 30295890 TI - A Tale of Two Compulsions - Two Case Studies Using Accelerated Resolution Therapy (ART) for Obsessive Compulsive Disorder (OCD). AB - Although research for accelerated resolution therapy (ART) has been predominately for post-traumatic stress disorder, ART has shown promise as a treatment for other behavioral health conditions as well. ART is a brief, trauma-focused, eye movement-based therapy that has been successfully utilized to treat a wide array of behavioral health disorders, including obsessive compulsive disorder. This article will present an overview of the theory behind the reconsolidation concept used in ART and two cases of obsessive compulsive disorder treatment using ART with outcome measures visual trend analysis. PMID- 30295891 TI - Misidentification of Burkholderia pseudomallei as Acinetobacter species in northern Thailand. AB - Background: Burkholderia pseudomallei is the causative agent of melioidosis, a disease endemic throughout the tropics. Methods: A study of reported Acinetobacter spp. bacteraemia was performed at Chiang Rai provincial hospital from 2014 to 2015. Isolates were collected and tested for confirmation. Results: A total of 419 putative Acinetobacter spp. isolates from 412 patients were re identified and 5/419 (1.2%) were identified as B. pseudomallei. Four of the five patients with melioidosis died. An estimated 88/419 (21%) isolates were correctly identified as Acinetobacter spp. Conclusions: Misidentification of Acinetobacter spp. as B. pseudomallei or other bacteria is not uncommon and programmes to address these shortfalls are urgently required. PMID- 30295892 TI - Functional conservation of a developmental switch in mammals since the Jurassic age. AB - ThPOK is a "master regulator" of T lymphocyte lineage choice, whose presence or absence is sufficient to dictate development to the CD4 or CD8 lineages, respectively. Induction of ThPOK is critically regulated at the transcriptional level, via a lineage-specific silencer element, SilThPOK. Here, we take advantage of the available genome sequence data as well as site-specific gene targeting technology, to evaluate the functional conservation of ThPOK regulation across mammalian evolution, and assess the importance of motif grammar (order and orientation of TF binding sites) on SilThPOK function in vivo. We make 3 important points: First, the SilThPOK is present in marsupial and placental mammals, but is not found in available genome assemblies of non-mammalian vertebrates, indicating that it arose after divergence of mammals from other vertebrates. Secondly, by replacing the murine SilThPOK in situ with its marsupial equivalent using a knockin approach, we demonstrate that the marsupial SilThPOK supports correct CD4 T lymphocyte lineage-specification in mice. To our knowledge, this is the first in vivo demonstration of functional equivalency for a silencer element between marsupial and placental mammals using a definitive knockin approach. Finally, we show that alteration of the position/orientation of a highly conserved region within the murine SilThPOK is sufficient to destroy silencer activity in vivo, demonstrating that motif grammar of this "solid" synteny block is critical for silencer function. Dependence of SilThPOK function on motif grammar conserved since the mid-Jurassic age, 165 million years ago, suggests that the SilThPOK operates as a silenceosome, by analogy with the previously proposed enhanceosome model.

PMID- 30295894 TI - A Pilot Comparison of Multispectral Fluorescence to Indocyanine Green Videoangiography and Other Modalities for Intraoperative Assessment in Vascular Neurosurgery. AB - BACKGROUND: Digital subtraction angiography (DSA) is the gold standard for vascular imaging, but is not easily integrated into a continuous microsurgical environment. Other available modalities for intraoperative vascular assessment have their own limitations. OBJECTIVE: To investigate multispectral fluorescence (MFL), a new technology based on indocyanine green (ICG) fluorescence, which may provide advantages over current intraoperative imaging modalities. METHODS: Cadaveric intracranial aneurysm models and turkey wing bypasses were created and tested with white light and micro-Doppler ultrasound, indocyanine green videoangiography (ICG-VA), MFL, and DSA in conditions mimicking surgery. Assessments with these modalities were scored by 7 neurosurgeons. RESULTS: DSA was significantly better than other modalities in evaluating the vasculature (P < .0001), but was significantly less ergonomic and efficient (P < .0001). MFL and ICG-VA were not significantly different from each other. Both were significantly better than white light/micro-Doppler ultrasound in assessing occlusion and patency (P <= .011), and both were better than DSA in ergonomics and efficiency (P < .0001). CONCLUSION: MFL performs similarly to ICG-VA in a laboratory setting. Further study will be required to determine whether it compares favorably in the operating room. While DSA is the standard for cerebrovascular visualization, MFL and ICG are significantly more ergonomic and efficient. PMID- 30295897 TI - Prenatal bisphenol A exposure alters epithelial cell composition in the rhesus macaque fetal oviduct. AB - Bisphenol A (BPA) is an endocrine disrupting compound that is a pervasive environmental contaminant. Although it has been reported to affect the development of a variety of fetal reproductive tissues, data on the effect of fetal BPA exposure on oviducts were extremely limited and were only available in mice. To determine if there are adverse effects of gestational BPA exposure on fetal oviduct, we exposed pregnant rhesus macaques with female fetuses to oral or non-oral BPA during the last trimester of gestation (day 100 to term). After the treatment, fetal oviducts were collected for morphology evaluation. BPA exposure altered the percentages of different cell types (ciliated, non-ciliated, and secretory) in the fetal oviduct and resulted in a significant high ciliated cell population in the BPA-exposed fetal oviduct. The distribution of ciliated cells on the epithelium in the BPA-exposed fetal oviduct was also altered. Gestational BPA exposure reduced the expression of mucosubstance and uteroglobin in secretory cells in the fetal oviduct. A comparison of the outcome of the fetal oviduct studies with similar outcomes previously reported in the lung from the same fetuses demonstrates that BPA exhibits opposite effects in these two organs. In conclusion, the BPA-associated alterations in the fetal oviduct could potentially affect the oviduct morphology and function later in life with a negative impact fertility. The mechanisms of action of the differential response of the oviduct and lung to BPA exposure require further investigation. PMID- 30295898 TI - Variation in ICE1 Methylation Primarily Determines Phenotypic Variation in Freezing Tolerance in Arabidopsis Thaliana. AB - Cold stress is a major abiotic factor plants face during their life cycle. Although plants often exhibit phenotypic variation in cold tolerance, the underlying mechanism remains poorly understood. In the present study, the 50% lethal temperature (LT50) values of 37 Arabidopsis thaliana accessions at latitudes from 15 degrees to 58 degrees ranged from -13.2 degrees C to -4.9 degrees C and were closely correlated with the cold climates of the collection sites. According to a methylation analysis of all C-repeat (CRT)-binding factor (CBF) pathway genes, the coding and promoter regions of AtICE1, a regulator of CBF genes, exhibited the greatest variability in methylation levels among the accessions and included 5 to 122 methylated cytosine residues. In contrast, unmethylated or only slightly methylated genes in the CBF pathway showed little variation among the accessions. According to a gene expression analysis of four selected A. thaliana populations with distinct methylation patterns, except for the downregulated gene AtCBF2, the expression levels of all members of the CBF pathway were negatively correlated with AtICE1 gene methylation levels. Treatment of the four A. thaliana populations with the DNA methylation inhibitory reagent 5 azacytidine resulted in a 30.0-78.3% enhancement of freezing tolerance and decreases in LT50 values of approximately 1.9-3.6 degrees C. Similar effects were observed in drm2 mutants, including 30.0-48.3% increases in freezing tolerance and decreases in LT50 values of approximately 0.7-3.4 degrees C. Thus, the AtICE1 methylation-regulated transcription of CBF pathway genes is responsible for the phenotypic variation in the freezing tolerance observed in A. thaliana. PMID- 30295899 TI - Isolation and characterization of Chlamydomonas autophagy-related mutants in nutrient-deficient conditions. AB - Autophagy is a recycling system for amino acids and carbon- and nitrogen (N) containing compounds. To date, the functional importance of autophagy in microalgae in nutrient-deficient conditions has not been evaluated by using autophagy-defected mutants. Here, we provide a series of evidence which support the following notions by characterizing an insertional mutant of the autophagy related gene ATG8, encoding a ubiquitin-like protein necessary for the formation of the autophagosome in the green alga, Chlamydomonas reinhardtii. First, ATG8 is required for maintenance of cell survival and chlorophyll content in the N-, sulfur-, and phosphate-deficient conditions. Second, ATG8 supports the degradation of triacylglycerol and lipid droplets after the resupply of N to cells cultured in N-limiting conditions. Third, ATG8 is also necessary for accumulation of starch in phosphate-deficient conditions. Additionally, autophagy is not essential for maternal inheritance of the organelle genomes in gametogenesis. PMID- 30295900 TI - Paramedian Supracerebellar Approach in Semi-Sitting Position for Endoscopic Resection of Pineal Cyst: 2-Dimensional Operative Video. AB - In this video, we present the case of a 41-yr-old female with new onset of recurrent syncopal episodes. She underwent extensive evaluations and diagnostic work-up by cardiology and neurology, excluding any other cause than a large pineal cyst that was found on magnetic resonance imaging. Surgical indications for pineal cyst resection are very limited as most pineal cyst can be treated conservatively. Recurrent drop-attacks (without loss of consciousness) or syncopal episodes (with brief loss of consciousness) have been associated with pineal cysts secondary to a possible ball valve effect with shift of position causing sudden obstruction of the ventricular system followed by rapid rising of intracranial pressure. Several approaches, different positions, and alternative surgical techniques (microscopic vs endoscopic) have been proposed for resection of pineal region lesions. The semi-sitting position provides excellent exposure of the pineal region secondary to gravity-based retraction of the cerebellum, and carries minimal risk of air venous embolism when head elevation is reduced to 30 degrees and lower extremities are elevated. The paramedian supracerebellar approach is less invasive and faster than midline supracerebellar approach, because it requires exposure of just 1 transverse sinus (nondominant for centered lesions) and avoids exposure of the torcula. The endoscopic technique greatly improves the ergonomics of the approach when compared to the microscope based technique, and provides excellent visualization of all the neurovascular structures in the pineal region. Surgical resection was successfully performed with no complications and complete cyst resection. Patient was discharged on postoperative day 1 and remains free of syncopal episodes. The patient signed informed consent including the use of photographic and video material for educational or academic purposes. PMID- 30295901 TI - Spatial analysis of dengue, cysticercosis and Chagas disease mortality in Ecuador, 2011-2016. AB - Background: Neglected tropical diseases (NTDs) continue to be an important cause of disability and mortality in the poorest tropical and subtropical areas. Methods: This is an ecological study. We included all death certificates with dengue, cysticercosis and Chagas disease in Ecuador from 2011 to 2016. The spatial autocorrelation was evaluated by GeoDa software through the Global Moran's I index and the formation of clusters by the local index of spatial association. Results: The Global Moran's I index for the study period shows a positive spatial autocorrelation for dengue, cysticercosis and Chagas disease (0.25, p=0.001; 0.07, p=0.04; 0.45, p=0.001, respectively). Conclusions: The clusters identified as higher risk in the country could be targeted by policymakers to adequately develop strategies to strengthen health promotion policies that break the cycle of these diseases. PMID- 30295902 TI - Implantation of a Thoracic Spinal Cord Stimulator Paddle Electrode and Generator Under General Anesthesia With Intraoperative Neuromonitoring: 2-Dimensional Operative Video. AB - Spinal cord stimulation is a well-established and effective therapy in the treatment of pain. Proper patient selection and accurate lead placement are paramount in its success. Placement is a multifaceted process requiring proper paddle placement, a well thought out generator placement and appropriate means to limit complications and enhance success. Several intraoperative techniques maximize outcomes, including removal of the superior portion of the inferior level's spinous process for paddle access into the epidural space, generator pocket placement in a location that limits patient discomfort, a strain relief loop at the thoracic incision to prevent lead fractures and allow for full spinal flexibility, generator placement parallel to the body and secured in the pocket to prevent unwanted movement, and intraoperative neuromonitoring for patient comfort and more accurate lead placement compared to X-ray alone or awake placement. This case demonstrates these key elements of intraoperative technique in a candidate with the most common indication for spinal cord stimulator placement-postlaminectomy syndrome-underscoring the ease and viability of this procedure in the appropriate patient population in a means that reduces future complications and adverse events while maximizing success. Full patient consent for video-recording and subsequent use for research purposes was attained. All patient identifiers have been removed for the purpose of patient confidentiality. PMID- 30295903 TI - A SOC1-like gene MtSOC1a promotes flowering and primary stem elongation in Medicago. AB - Medicago flowering, like that of Arabidopsis, is promoted by vernalization and long days, but alternative mechanisms are predicted because Medicago lacks the key regulators CO and FLC. Three Medicago SOC1-like genes, including MtSOC1a, were previously implicated in flowering control, but no legume soc1 mutants with altered flowering were reported. Here, reverse transciption-quantitative PCR (RT qPCR) indicated that the timing and magnitude of MtSOC1a expression was regulated by the flowering promoter FTa1, while in situ hybridization indicated that MtSOC1a expression increased in the shoot apical meristem during the floral transition. A Mtsoc1a mutant showed delayed flowering and short primary stems. Overexpression of MtSOC1a partially rescued the flowering of Mtsoc1a, but caused a dramatic increase in primary stem height, well before the transition to flowering. Internode cell length correlated with stem height, indicating that MtSOC1a promotes cell elongation in the primary stem. However, application of gibberellin (GA3) caused stem elongation in both the wild type and Mtsoc1a, indicating that the mutant was not defective in gibberellin responsiveness. These results indicate that MtSOC1a may function as a floral integrator gene and promotes primary stem elongation. Overall, this study suggests that apart from some conservation with the Arabidopsis flowering network, MtSOC1a has a novel role in regulating aspects of shoot architecture. PMID- 30295904 TI - Greater lateral root branching density in maize improves phosphorus acquisition from low phosphorus soil. AB - The development of crops with better growth under suboptimal phosphorus availability would improve food security in developing countries while reducing environmental pollution in developed countries. We tested the hypothesis that maize (Zea mays) phenotypes with greater lateral root branching density have greater phosphorus acquisition from low phosphorus soils. Recombinant inbred lines with either 'many short' (MS) or 'few long' (FL) lateral root phenotypes were grown under high and low phosphorus conditions in greenhouse mesocosms and in the field. Under low phosphorus in mesocosms, lines with the MS phenotype had 89% greater phosphorus acquisition and 48% more shoot biomass than FL lines. Under low phosphorus in the field, MS lines had 16% shallower rooting depth (D95), 81% greater root length density in the top 20 cm of the soil, 49% greater shoot phosphorus content, 12% greater leaf photosynthesis, 19% greater shoot biomass, and 14% greater grain yield than FL lines. These results are consistent with the hypothesis that the phenotype of many, shorter lateral roots improves phosphorus acquisition under low phosphorus availability and merits consideration for genetic improvement of phosphorus efficiency in maize and other crops. PMID- 30295906 TI - Automated morphological feature assessment for zebrafish embryo developmental toxicity screens. AB - Detection of developmental phenotypes in zebrafish embryos typically involves a visual assessment and scoring of morphological features by an individual researcher. Subjective scoring could impact results and be of particular concern when phenotypic effect patterns are also used as a diagnostic tool to classify compounds. Here we introduce a quantitative morphometric approach based on image analysis of zebrafish embryos. A software called FishInspector was developed to detect morphological features from images collected using an automated system to position zebrafish embryos. The analysis was verified and compared with visual assessments of three participating laboratories using three known developmental toxicants (methotrexate, dexamethasone and topiramate) and two negative compounds (loratadine and glibenclamide). The quantitative approach exhibited higher sensitivity and made it possible to compare patterns of effects with the potential to establish a grouping and classification of developmental toxicants. Our approach improves the robustness of phenotype scoring and reliability of assay performance and, hence, is anticipated to improve the predictivity of developmental toxicity screening using the zebrafish embryo. PMID- 30295907 TI - Left Pan-Hippocampal Low Grade Glioma-2-Stage Transsylvian Transventricular and Paramedian Supracerebellar Transtentorial Approaches: 2-Dimensional Operative Video. AB - The surgical goal for low-grade gliomas (LGGs) is to maximize resection while minimizing morbidity. Pan-hippocampal LGGs extend from the hippocampal head to the hippocampal tail, and involve the parahippocampal gyrus and uncus. Given their anteroposterior extension, they cannot be completely removed with 1 single approach, requiring a 2-stage front-to-back operation. In this video, we present the case of a 52-yr-old man with new onset of generalized seizures and a dominant side, nonenhancing, pan-hippocampal infiltrative lesion compatible with a low grade glioma. Preoperative high-definition fiber tractography (HDFT) showed the spatial relationship of the tumor with surrounding fiber tracts, such as the arcuate, inferior fronto-occipital, and middle longitudinal fascicles, and optic radiations. Surgical resection was planned in 2 separate stages. The first stage consisted of a transsylvian transinferior insular sulcus approach to the extra- and intraventricular aspects of the uncohippocampal region. The entire anterior and middle portions of the tumor were successfully removed with minimal morbidity, including transient naming difficulties and permanent superior quadrantanopia. Postoperative HDFT showed preservation of all fiber tracts, except for a portion of Meyer's loop and the inferior-most aspect of the inferior fronto-occipital fascicle. The second stage was completed 8 wk later and consisted of a paramedian supracerebellar-transtentorial approach on sitting position. The posterior portion of the tumor was entirely removed to achieve a complete macroscopic tumor resection. The final diagnosis was IDH1-positive LGG. Pan-hippocampal tumors remain a surgical challenge but accurate knowledge of surgical neuroanatomy and surgical approaches facilitates their safe and effective treatment. The patient signed an informed consent including the use of photographic and video material for educational or academic purposes. PMID- 30295905 TI - Gnp4/LAX2, a RAWUL protein, interferes with the OsIAA3-OsARF25 interaction to regulate grain length via the auxin signaling pathway in rice. AB - Grain length is one of the determinants of yield in rice and auxin plays an important role in regulating it by mediating cell growth. Although several genes in the auxin pathway are involved in regulating grain length, the underlying molecular mechanisms remain unclear. In this study we identify a RING-finger and wd40-associated ubiquitin-like (RAWUL) domain-containing protein, Gnp4/LAX2, with a hitherto unknown role in regulation of grain length by its influence on cell expansion. Gnp4/LAX2 is broadly expressed in the plant and subcellular localization analysis shows that it encodes a nuclear protein. Overexpression of Gnp4/LAX2 can significantly increase grain length and thousand-kernel weight. Moreover, Gnp4/LAX2 physically interacts with OsIAA3 and consequently interferes with the OsIAA3-OsARF25 interaction in vitro and in vivo. OsIAA3 RNAi plants consistently exhibit longer grains, while the mutant osarf25 has small grains. In addition, OsARF25 binds to the promoter of OsERF142/SMOS1, a regulator of organ size, and positively regulates its expression. Taken together, the results reveal that Gnp4/LAX2 functions as a regulator of grain length through participation in the OsIAA3-OsARF25-OsERF142 pathway and that it has potential value for molecular breeding in rice. PMID- 30295908 TI - Generalized Bootstrap Supports for Phylogenetic Analyses of Protein Sequences Incorporating Alignment Uncertainty. AB - Phylogenetic reconstructions are essential in genomics data analyses and depend on accurate multiple sequence alignment (MSA) models. We show that all currently available large-scale progressive multiple alignment methods are numerically unstable when dealing with amino-acid sequences. They produce significantly different output when changing sequence input order. We used the HOMFAM protein sequences dataset to show that on datasets larger than 100 sequences, this instability affects on average 21.5% of the aligned residues. The resulting Maximum Likelihood (ML) trees estimated from these MSAs are equally unstable with over 38% of the branches being sensitive to the sequence input order. We established that about two-thirds of this uncertainty stems from the unordered nature of children nodes within the guide trees used to estimate MSAs. To quantify this uncertainty we developed unistrap, a novel approach that estimates the combined effect of alignment uncertainty and site sampling on phylogenetic tree branch supports. Compared with the regular bootstrap procedure, unistrap provides branch support estimates that take into account a larger fraction of the parameters impacting tree instability when processing datasets containing a large number of sequences. PMID- 30295909 TI - Mesenteric Adipose Tissue Alterations in Crohn's Disease Are Associated With the Lymphatic System. AB - Background: Mesenteric fat wrapping and thickening are typical characteristics of Crohn's disease (CD). The purpose of this study was to explore the cause of mesenteric adipose hypertrophy and analyze the role of lymphatic vessels in mesenteric adipose tissue in CD. Methods: Twenty-three CD patients who underwent ileocolonic resection were included. In CD patients, specimens were obtained from hypertrophic mesenteric adipose tissue (htMAT) next to the diseased ileum. The mesenteric lymphatic vessels in mesenteric adipose tissue were separated under stereoscope microscope. Transmission electron microscopy and immunofluorescence were used to observe the structure of mesenteric lymphatic vessels. The NF-kappaB signaling pathway in mesenteric adipose tissue was detected in CD specimens using Western blotting. Results: Electron microscopy showed that the structure of mesenteric lymphatic vessel was discontinuous, and the microstructure of lymphatic endothelial cells appeared ruptured and incomplete. Through an immunofluorescence technique, we found that the surface of lymphatic endothelial cells lacked tight junction protein staining in CD. Also, the expression of claudin-1, occludin, and ZO-1 in the mesenteric lymphatic vessel of htMAT was significantly lower than that of control. These results indicated that the structure of the mesenteric lymphatic vessel in htMAT was mispatterned and ruptured, which could lead to lymph leakage. Leaky lymph factors could stimulate adipose tissue to proliferate. Antigens that leaked into the mesenteric adipose tissue could effectively elicit an immune response. The levels of cytokines (TNF a, IL-1beta, IL-6) was increased in the htMAT of CD patients by activated NF kappaB signaling pathway. Conclusions: Our findings demonstrated that the hypertrophy of mesenteric adipose tissue may result from mispatterned and ruptured lymphatic vessels.

AB - Metabolic transformation of zearalenone (ZEA), a mycotoxin which can contaminate both food and feed, results in the formation of five metabolites, one of them being zeranol (alpha-ZAL), which can be abused in farm animals as a growth promoter. To the best of our knowledge, there is no analytical method that can distinguish whether alpha-ZAL is present in an animal urine sample as a result of ZEA biotransformation or as a result of anabolic abuse. This study aimed at monitoring resorcylic acid lactones (RALs) concentration in urine of farm animals over several years. Six hundred and three cattle and pig urine samples were collected on farms in different Croatian regions and analyzed for RAL presence. Based on the testing results, all RAL-positive samples were considered to be consequential to feed contamination. The difference in primary ZEA metabolites' ratio (alpha-zearalenol/beta-zearalenol) was observed between cattle (0.03-0.41) and pig (2.05-17.39) urine samples. If the animals are treated with alpha-ZAL and fed on ZEA-contaminated feed, alpha-ZAL and taleranol found in their organisms could come from two sources, so that the reliability of the statistical model might be questionable. Based on these findings, there exists the need for improving the approach to the distinction between alpha-ZAL abuse and ZEA feed contamination. PMID- 30295911 TI - Verticillium dahliae Alt a 1-like protein PevD1 targets cotton PR5-like protein and contributes to fungal infection. AB - Alt a 1 family proteins (AA1s) have only been observed in the Dothideomycetes and Sordariomycetes classes of fungi, and their biological functions have been poorly understood to date. Verticillium dahliae, a soil-borne pathogen that causes plant verticillium wilt disease, secretes hundreds of proteins during the process of pathogenic infection, including the AA1s member PevD1. The pevd1 transcript was present in all of the hosts studied and showed elevated expression throughout the infection process. Furthermore, pevd1 knockout mutants displayed attenuated pathogenicity compared with the wild type (WT) strain and complemented strains in hosts. A partner protein of PevD1, pathogenesis-related protein 5 (PR5)-like protein GhPR5, was isolated from cotton plants by co-purification assays, and the PevD1-GhPR5 interaction was further confirmed by a pull-down assay. The GhPR5 interacting region of PevD1 was determined to be located in the C-terminus (PevD1b, amino acids residues 113-155) via pull-down and Y2H techniques. Reintroduction of the pevd1b gene into a pevd1 knockout mutant resulted in restoration of the virulence phenotype to WT levels. Moreover, PevD1b, similar to PevD1, decreased the antifungal activity of GhPR5 in vitro. Our findings highlight a new infection strategy in which V. dahliae secretes PevD1 to inhibit GhPR5 antifungal activity to overcome the host defence system.

AB - Introduction: There is evidence that yoga may be helpful as an aid for smoking cessation. Yoga has been shown to reduce stress and negative mood and may aid weight control, all of which have proven to be barriers to quitting smoking. This study is the first rigorous, randomized clinical trial of yoga as a complementary therapy for smokers attempting to quit. Methods: Adult smokers (n=227; 55% women) were randomized to an 8-week program of cognitive-behavioral smoking cessation and either twice-weekly Iyengar Yoga, or general Wellness classes (control). Assessments included cotinine verified 7-day point prevalence abstinence (7PPA) at week 8, 3-month and 6-month follow-ups. Results: At baseline participants' mean age was 46.2 years (SD=12.0), smoking rate 17.3 cigarettes/day (SD=7.6). Longitudinally adjusted models of abstinence outcomes demonstrated significant group effects favoring Yoga. Yoga participants had 37% greater odds of achieving abstinence than Wellness participants at EOT. Lower baseline smoking rates (<=10 cigarettes/day) were also associated with higher likelihood of quitting if given Yoga vs. Wellness (OR=2.43, 95% CI: 1.09-6.30) at EOT. A significant dose effect was observed for yoga (OR=1.12, 95% CI: 1.09-1.26), but not Wellness, such that each yoga class attended increased quitting odds at EOT by 12%. Latent Class Modeling revealed a 4-class model of distinct quitting patterns among participants. Conclusions: Yoga appears to increase the odds of successful smoking abstinence, particularly among light smokers. Additional work is needed to identify predictors of quitting patterns and inform adjustments to therapy needed to achieve cessation and prevent relapse. PMID- 30295913 TI - The impact of coronary angiography on renal transplant function. AB - Background: There may be reluctance to perform coronary angiography in kidney transplant patients due to perceived risk of iodinated contrast, despite an increased risk of cardiovascular disease compared with the general population. Aim: We sought to determine if renal transplant function was adversely affected within 7, 30 and 180 days of coronary angiography. Methods: Renal transplant recipients undergoing coronary angiography in a single centre (01/2006-02/2018) were identified retrospectively. Baseline and highest SCr within 7, 30 and 180 days of coronary angiography were extracted from the electronic patient record. Rise in creatinine >26 micromol/l was considered significant (equivalent to Acute Kidney Injury (AKI) Network criteria stage 1 AKI) and case note review performed to determine circumstance of renal decline. Results: There were 127 coronary angiographies conducted in 90 patients: 67.7% were male and mean age was 58.0 (+/ 10.1) years. There was AKI within 7 days in 18.9% cases, but SCr returned to baseline within 7 days or there was an alternative explanation for AKI in 83.3% of these. In the remaining 4 cases, there was progressive decline in renal transplant function. In the absence of critical illness, no patient required dialysis or extended hospital stay for contrast-associated AKI. Conclusions: In this cohort of renal transplant recipients undergoing coronary angiography, AKI occurred in a minority of cases, and in more than 95% of such cases this effect was transient, with progressive renal decline a rare and predictable event. Renal transplant should not be regarded as a contraindication to coronary angiography. PMID- 30295914 TI - Mindfulness and progressive muscle relaxation as standardized session introduction in individual therapy: A randomized controlled trial. AB - OBJECTIVE: There is scarce research on the effects of mindfulness in individual therapy. As many practitioners integrate mindfulness exercises into individual therapy, empirical evidence is of high clinical relevance. METHOD: We investigated the effects of a session-introducing intervention with mindfulness elements (SIIME) in a randomized, controlled design. The effects of SIIME on therapeutic alliance and symptomatic outcome were compared with progressive muscle relaxation (PMR) and treatment-as-usual (TAU) control conditions. The sample comprised 162 patients with anxiety and depression. RESULTS: Multilevel modeling revealed a significant symptom reduction and significant increase of alliance over the course of therapy. There were no significant time-condition interactions on outcome and alliance, indicating the comparable efficiency of all three treatment conditions. CONCLUSIONS: We found no advantage of SIIME versus PMR and TAU. Add-on mindfulness might not improve individual therapy related to alliance and outcome. PMID- 30295915 TI - Discrimination and Ethnic-Racial Socialization Among Youth Adopted From South Korea Into White American Families. AB - The current study examined how discrimination relates to adjustment outcomes in a sample of internationally, transracially adopted Korean Americans from the Minnesota Sibling Interaction and Behavior Study (N = 456 adoptees; Mage at T1 = 14.9, Mage at T2 = 18.3, Mage at T3 = 22.3). The moderating roles of ethnic socialization and preparation for bias by parents (i.e., ethnic-racial socialization) were also examined. Results indicated that discrimination predicted higher levels of depressive and externalizing symptoms in youth who reported less preparation for bias. In those experiencing more preparation for bias, associations were not significantly different from zero. Ethnic socialization did not moderate these associations. Such findings provide important information for adoptive parents regarding how to prepare their children to cope with discrimination. PMID- 30295916 TI - Astrocyte support is important for the compensatory potential of the nigrostriatal system neurons during early neurodegeneration. AB - Glial pathology precedes symptoms of Parkinson's disease (PD) and multiple other neurodegenerative diseases. Prolonged impairment of astrocytic functions could increase the vulnerability of dopaminergic neurons in the substantia nigra (SN), accelerate their degeneration and affect ability to compensate for partial degeneration at the presymptomatic stages of the disease. The aim of this study was to investigate the astrocyte depletion in the SN, its impact on the dopaminergic system functioning and multiple markers of energy metabolism during the early stages of neurodegeneration and compensation. We induced death of 30% of astrocytes by chronic infusion of fluorocitrate (FC) into the SN, simultaneously activating microglia response but sparing the dopaminergic neurons. The FC effect was reversible after toxin withdrawal. Dopaminergic neurons were killed by 6-hydroxydopamine causing transient locomotor disability, reversed with time showing compensatory potential. Death of astrocytes diminished the capability of the dopaminergic system to compensate for the degeneration of neurons and caused a local energy deprivation by decreasing lactate and glycogen amount. Studied markers suggest a shift in the usage of energy substrates, via increased glycogenolysis and glycolysis markers, ketone bodies availability and fatty acid transport in remaining glial cells. PGC-1alpha and AMPK, the energy sensors, showed different regulation between the cell-types. Increased neuronal expression of CPT1c could play a role in the adaptation to metabolic stress in response to glia dysfunction. Astrocyte energetic support is one of the essential factors for neuronal compensatory mechanisms of dopaminergic system and might have a leading role in the presymptomatic PD stages.

PMID- 30295917 TI - Preparation and Characterization of Lactobacilli-Loaded Composite Films with Sustaining Antipathogenic Activity and Preservation Effect. AB - : Bioactive composite films were obtained by adding Lactobacillus paracasei into a hydroxypropyl cellulose (HPC)-konjac flour (KF) matrix through a casting method. The mechanical, optical, and barrier properties were tested to determine the influence of the addition of lactobacilli into complex films. For purpose of evaluating the surface morphology of the composite films, scanning electron microscopy and atomic force microscopy were carried out. Fourier transform infrared spectroscopy and X-ray diffraction analyses were conducted to evaluate intermolecular interactions and crystallinity, respectively. Moreover, the microbial viability of the lactobacilli and the antibacterial activities of the bioactive films against pathogenic organisms were measured. The results indicated that the mechanical properties, crystalline properties, oxygen permeability, and color characteristics were not notably altered; nevertheless, the gloss and water vapor barrier properties were relatively weakened by the incorporation of L. paracase. The HPC-KF-L. paracasei films were effective in inhibiting both gram positive (Listeria monocytogenes, Staphylococcus aureus) and gram-negative (Escherichia coli, Salmonella typhimurium) pathogens, and the films can retain physical property and antibacterial activity within a storage period of 30 days. The composite films, acting as suitable carriers for L. paracasei and possessing noteworthy bacteriostatic activities, could be developed as bioactive packaging for preserving food. PRACTICAL APPLICATION: For the sake of the high desires of consumers for food safety and quality, the development of innovative bioactive packaging has attracted wide attention. In this work, the prepared films containing lactic acid bacteria showed great physical property, antipathogenic activity, and fresh-keeping property preservation, and have great application potential in fresh food preservation. PMID- 30295918 TI - The Impact of Caregiving Disruptions of Previously Institutionalized Children on Multiple Outcomes in Late Childhood. AB - This study examined disruptions in caregiving, as well as the association of these disruptions, with cognitive, behavioral, and social outcomes at age 12 in a sample of 136 Romanian children who were abandoned to institutions as infants and who experienced a range of subsequent types of care. Children were found to experience significantly more caregiving disruptions (CGD) earlier in life than later in childhood. More frequent CGD predicted increases in externalizing and internalizing behavior problems at age 12. Results are discussed in terms of the association between CGD and the long-term development of children who have experienced institutional rearing. PMID- 30295919 TI - Methamphetamine decreases K+ channel function in human fetal astrocytes by activating the trace amine-associated receptor type-1. AB - Methamphetamine (Meth) is a potent and commonly abused psychostimulant. Meth alters neuron and astrocyte activity; yet the underlying mechanism(s) is not fully understood. Here we assessed the impact of acute Meth on human fetal astrocytes (HFAs) using whole-cell patch-clamping. We found that HFAs displayed a large voltage-gated K+ efflux (IKv ) through Kv /Kv -like channels during membrane depolarization, and a smaller K+ influx (Ikir ) via inward-rectifying Kir /Kir -like channels during membrane hyperpolarization. Meth at a 'recreational' (20 MUM) or toxic/fatal (100 MUM) concentration depolarized resting membrane potential (RMP) and suppressed IKv/Kv-like . These changes were associated with a decreased time constant (T), and mimicked by blocking the two pore domain K+ (K2P )/K2P -like and Kv /Kv -like channels, respectively. Meth also diminished IKir/Kir-like , but only at toxic/fatal levels. Given that Meth is a potent agonist for the trace amine-associated receptor type-1 (TAAR1), and TAAR1-coupled cAMP/cAMP-activated protein kinase (PKA) cascade, we further evaluated whether the Meth impact on K+ efflux was mediated by this pathway. We found that antagonizing TAAR1 with N-(3-Ethoxyphenyl)-4-(1-pyrrolidinyl)-3 (trifluoromethyl)benzamide (EPPTB) reversed Meth-induced suppression of IKv/Kv like ; and inhibiting PKA activity by H89 abolished Meth effects on suppressing IKv/Kv-like . Antagonizing TAAR1 might also attenuate Meth-induced RMP depolarization. Voltage-gated Ca2+ currents were not detected in HFAs. These novel findings demonstrate that Meth suppresses IKv/Kv-like by facilitating the TAAR1/Gs /cAMP/PKA cascade and altering the kinetics of Kv /Kv -like channel gating, but reduces K2P /K2P -like channel activity through other pathway(s), in HFAs. Given that Meth-induced decrease in astrocytic K+ efflux through K2P /K2P like and Kv /Kv -like channels reduces extracellular K+ levels, such reduction could consequently contribute to a decreased excitability of surrounding neurons.

AB - INTRODUCTION: Development and behaviour in Cornelia de Lange Syndrome (CdLS), including autism characteristics, have been described infrequently stratified to genetic cause and only a few studies have considered behavioural characteristics in relation to developmental level. Here, we describe the behavioural phenotype in individuals with CdLS with SMC1A variants. METHODS: We performed an international, interdisciplinary study on 51 individuals with SMC1A variants. Results of questionnaire studies are compared to those in individuals with Down Syndrome and with Autism Spectrum Disorder. Results on cognition and self injurious behaviour (SIB) are compared to those in individuals with CdLS caused by NIPBL variants. For Dutch participants with SMC1A variants we performed direct in-person assessments of cognition, autism, and added an interview and questionnaire on adaptive behaviour and sensory processing. RESULTS: Individuals with SMC1A variants show a higher cognitive level and less SIB than individuals with NIPBL variants. Individuals with SMC1A variants without classic CdLS phenotype but with a Rett-like phenotype show more severe intellectual disability and more SIB compared to those with a CdLS phenotype. Autism is less present if outcomes in direct in-person assessments are evaluated taking developmental level into account compared to results based on a questionnaire. CONCLUSIONS: Behaviour in individuals with CdLS should be evaluated taking genetic cause into account. Detailed interdisciplinary approaches are of clinical importance to inform tailored care and may eventually improve quality of life of patients and families. PMID- 30295921 TI - Keys to the Gate? Equal Sign Knowledge at Second Grade Predicts Fourth-Grade Algebra Competence. AB - Algebraic competence is a major determinant of college access and career prospects, and equal sign knowledge is taken to be foundational to algebra knowledge. However, few studies have documented a causal effect of early equal sign knowledge on later algebra skill. This study assessed whether second-grade students' equal sign knowledge prospectively predicts their fourth-grade algebra knowledge, when controlling for demographic and individual difference factors. Children (N = 177; Mage = 7.61) were assessed on a battery of tests in Grade 2 and on algebraic knowledge in Grade 4. Second-grade equal sign knowledge was a powerful predictor of these algebraic skills. Findings are discussed in terms of the importance of foregrounding equal sign knowledge to promote effective pedagogy and educational equity. PMID- 30295922 TI - Oral health and access to dental care among older homeless adults: results from the HOPE HOME study. AB - OBJECTIVES: To describe the prevalence of and factors associated with oral health measures in a sample of older homeless adults in Oakland, CA. METHODS: We conducted a cross-sectional analysis of data from a population-based study of 350 homeless adults aged >=50 in which trained researchers conducted structured interviews using validated questions regarding sociodemographics, health-related behaviors, healthcare utilization, and health status. We assessed self-reported tooth loss, oral pain, and unmet need for dental care. We used multivariable logistic regression to examine factors associated with missing half or more teeth. RESULTS: Over half 201/350 (57.4 percent) of participants were missing at least half of their teeth. Half 191/350 (54.6 percent) reported oral pain in the past 6 months; 101/350 (28.9 percent) reported that oral pain prevented them from eating and 73/350 (20.9 percent) reported that pain prevented sleeping. Almost half, 141/350 (40.3 percent), had not seen a dentist in over 5 years, and over half 190/350 (54.3 percent) reported being unable to obtain needed dental care. In multivariate models, increased age (AOR = 1.09, 95 percent CI 1.04-1.14), moderate-to-high risk alcohol use (AOR = 2.17, CI = 1.23-3.84), moderate-to-high risk cocaine use (AOR = 1.72, CI = 1.03-2.88), and ever smoking (AOR = 2.87, CI = 1.59-5.18) were associated with an increased odds of having lost half or more teeth. CONCLUSIONS: Tooth loss and oral pain are highly prevalent in older homeless adults. Increasing age, alcohol, drug, and tobacco use are associated with tooth loss. PMID- 30295923 TI - Slow periodic activity in the longitudinal hippocampal slice can self-propagate non-synaptically by a mechanism consistent with ephaptic coupling. AB - KEY POINTS: Slow periodic activity can propagate with speeds around 0.1 m s-1 and be modulated by weak electric fields. Slow periodic activity in the longitudinal hippocampal slice can propagate without chemical synaptic transmission or gap junctions, but can generate electric fields which in turn activate neighbouring cells. Applying local extracellular electric fields with amplitude in the range of endogenous fields is sufficient to modulate or block the propagation of this activity both in the in silico and in the in vitro models. Results support the hypothesis that endogenous electric fields, previously thought to be too small to trigger neural activity, play a significant role in the self-propagation of slow periodic activity in the hippocampus. Experiments indicate that a neural network can give rise to sustained self-propagating waves by ephaptic coupling, suggesting a novel propagation mechanism for neural activity under normal physiological conditions. ABSTRACT: Slow oscillations are a standard feature observed in the cortex and the hippocampus during slow wave sleep. Slow oscillations are characterized by low-frequency periodic activity (<1 Hz) and are thought to be related to memory consolidation. These waves are assumed to be a reflection of the underlying neural activity, but it is not known if they can, by themselves, be self-sustained and propagate. Previous studies have shown that slow periodic activity can be reproduced in the in vitro preparation to mimic in vivo slow oscillations. Slow periodic activity can propagate with speeds around 0.1 m s-1 and be modulated by weak electric fields. In the present study, we show that slow periodic activity in the longitudinal hippocampal slice is a self regenerating wave which can propagate with and without chemical or electrical synaptic transmission at the same speeds. We also show that applying local extracellular electric fields can modulate or even block the propagation of this wave in both in silico and in vitro models. Our results support the notion that ephaptic coupling plays a significant role in the propagation of the slow hippocampal periodic activity. Moreover, these results indicate that a neural network can give rise to sustained self-propagating waves by ephaptic coupling, suggesting a novel propagation mechanism for neural activity under normal physiological conditions.

PMID- 30295925 TI - Identification of drug transporters contributing to oxaliplatin-induced peripheral neuropathy. AB - Oxaliplatin is widely used as a key drug in the treatment of colorectal cancer. However, its administration is associated with the dose-limiting adverse effect, peripheral neuropathy. Platinum accumulation in the dorsal root ganglion (DRG) is the major mechanism responsible for oxaliplatin-induced neuropathy. Some drug transporters have been identified as platinum complex transporters in kidney or tumor cells, but not yet in DRG. In the present study, we investigated oxaliplatin transporters and their contribution to peripheral neuropathy. We identified 12 platinum transporters expressed in DRG with real-time PCR, and their transiently overexpressing cells were established. After exposure to oxaliplatin, the accumulation of platinum in these overexpressing cells was evaluated using a coupled plasma mass spectrometer. Octn1/2- and Mate1-expressing cells showed the intracellular accumulation of oxaliplatin. In an animal study, peripheral neuropathy developed after the administration of oxaliplatin (4 mg/kg, intravenously, twice a week) to siRNA-injected rats (0.5 nmol, intrathecally, once a week) was demonstrated with the von Frey test. The knockdown of Octn1 in DRG ameliorated peripheral neuropathy, and decreased platinum accumulation in DRG, whereas the knockdown of Octn2 did not. Mate1 siRNA-injected rats developed more severe neuropathy than control rats. These results indicate that Octn1 and Mate1 are involved in platinum accumulation at DRG and oxaliplatin-induced peripheral neuropathy. PMID- 30295926 TI - From Amazonia to southern Africa: atmospheric moisture transport through low level jets and atmospheric rivers. AB - A Lagrangian analysis is applied to identify the main moisture source areas associated with atmospheric rivers (ARs) making landfall along the west coast of South Africa during the extended austral winter months from 1980 to 2014. The results show that areas that provide the anomalous uptake of moisture can be categorized into four regions: (1) the South Atlantic Ocean between 10 degrees S and 30 degrees S, (2) a clear local maximum in the eastern South Atlantic, (3) a continental source of anomalous uptake to the north of the Western Cape, and (4) over South America at a distance of more than 7000 km from the target region. It emerges that the South American moisture source can be linked to a particular phase of the South American low-level jet, known as a no Chaco jet event (NCJE), which transports moisture to the western and central South Atlantic basin. Concisely, we provide strong evidence that the two margins of the South Atlantic Ocean appear connected by two meteorological structures, with the NCJE playing a key role of transporting moisture from South America to the western and central South Atlantic basin, feeding the AR that transports some of the moisture to the west coast of South Africa. PMID- 30295927 TI - Long-Term Acute Care Hospital Use of Non-Mechanically Ventilated Hospitalized Older Adults. AB - OBJECTIVES: To determine why non-mechanically ventilated hospitalized older adults are transferred to long-term acute care (LTAC) hospitals rather than remaining in the hospital. DESIGN: Observational cohort. SETTING: National Medicare data. PARTICIPANTS: Non-mechanically ventilated hospitalized adults aged 65 and older with fee-for-service Medicare in 2012 who were transferred to an LTAC hospital (n=1,831) or had a prolonged hospitalization without transfer (average hospital length of stay or longer of those transferred to an LTAC hospital) and had one of the 50 most common hospital diagnoses leading to LTAC transfer (N=12,875). MEASUREMENTS: We assessed predictors of transfer using a multilevel model, adjusting for patient-, hospital-, and hospital referral region (HRR)-level factors. We estimated proportions of variance at each level and adjusted hospital- and HRR-specific LTAC transfer rates using sequential models. RESULTS: The strongest predictor of transfer was being hospitalized near an LTAC hospital (<1.4 vs > 33.6 miles, adjusted odds ratio=6.2, 95% confidence interval (CI)=4.2-9.1). After adjusting for case mix, differences between hospitals explained 15.4% of the variation in LTAC use and differences between regions explained 27.8%. Case mix-adjusted LTAC use was high in the South, where many HRRs had rates between 20.3% and 53.1%, whereas many HRRs were less than 5.4% in the Pacific Northwest, North, and New England. From our fully adjusted model, the median adjusted hospital LTAC transfer rate was 7.2% (interquartile range 2.8 17.5%), with substantial within-region variation (intraclass coefficient=0.25, 95% CI=0.21-0.30). CONCLUSIONS: Nearly half of the variation in LTAC use is independent of illness severity and is explained by which hospital and what region the individual was hospitalized in. Because of the greater fragmentation of care and Medicare spending with LTAC transfers (because LTAC hospitals generate a separate bundled payment from the hospital), greater attention is needed to define the optimal role of LTAC hospitals in caring for older adults.

Terrestrial laser scanning III. Turning points into trees IV. Current and future applications of TLS V. Conclusions Acknowledgements References SUMMARY: Terrestrial laser scanning (TLS) is providing new, very detailed three-dimensional (3D) measurements of forest canopy structure. The information that TLS measurements can provide in describing detailed, accurate 3D canopy architecture offers fascinating new insights into the variety of tree form, environmental drivers and constraints, and the relationship between form and function, particularly for tall, hard-to-measure trees. TLS measurements are helping to test fundamental ecological theories and enabling new and better exploitation of other measurements and models that depend on 3D structural information. This Tansley insight introduces the background and capabilities of TLS in forest ecology, discusses some of the barriers to progress, and identifies some of the directions for new work. PMID- 30295929 TI - Prediction models for postoperative uncontrolled chronic rhinosinusitis in daily practice. AB - OBJECTIVES/HYPOTHESIS: The European Position Paper on Rhinosinusitis and Nasal Polyps proposes an assessment of clinical control of chronic rhinosinusitis (CRS). However, there are limited data about the percentage of postoperative control, and no prediction models for uncontrolled CRS have been reported. The aim of the study was to develop prediction models for postoperative uncontrolled CRS. STUDY DESIGN: Retrospective case series. METHODS: Patients (n = 136) who had undergone endoscopic sinus surgery at least 1 year prior to the study were recruited to assess the clinical control. Risk factors were determined by logistic models and presented as odds ratio (OR) with a 95% confidence interval. Receiver operating characteristics curves were constructed to set the cutoff points and create predictive models. RESULTS: Approximately 47.8% of patients had controlled, 22.1% partially controlled, and 30.1% uncontrolled CRS. Univariate regression models revealed the risk factors for uncontrolled CRS: tissue eosinophilia, blood eosinophilia, high computed tomography (CT) score, bilateral disease, asthma, and allergic rhinitis. Multiple regression models found tissue eosinophil ratio >0.206 (OR: 12.96, P = .001) or blood eosinophil ratio >0.025 (OR: 4.56, P = .003), Lund-Mackay (LM) score >= 15 (OR: 15.50, P < .001) and CT ethmoid (E) score >= maxillary (M) score (OR: 3.51, P = .037) were independent risk factors. We generated a pathological model (tissue eosinophil ratio and LM score) and a clinical model (blood eosinophil ratio, LM score and E >= M score) to categorize CRS into mild, moderate, and severe. CONCLUSIONS: This research provides simplified and efficient prediction models for uncontrolled CRS. It may help otolaryngologists to predict the prognosis before surgery in daily practice. LEVEL OF EVIDENCE: 2b Laryngoscope, 2018. PMID- 30295930 TI - Gastroenteropancreatic Neuroendocrine Tumors. AB - Neuroendocrine tumors (NETs) are heterogeneous malignancies arising from the diffuse neuroendocrine system. They frequently originate in the gastroenteropancreatic (GEP) tract and the bronchopulmonary tree, and their incidence has steadily increased in the last 3 decades. Fundamental biologic and genomic differences underlie the clinical heterogeneity of NETs, and distinct molecular features characterize NETs of different grades and different primary sites. Although surgery remains the cornerstone of treatment for localized tumors, systemic treatment options for patients with metastatic NETs have expanded considerably. Somatostatin analogs have demonstrated both antisecretory and antitumor efficacy. Peptide receptor radionuclide therapy with lutetium-177 dotatate (177 Lu-DOTATATE) has been approved for advanced GEP-NETs. The antitumor activity of everolimus has been demonstrated across a wide spectrum of NETs, and the antiangiogenic agent sunitinib has been approved for pancreatic NETs (pNETs). Chemotherapy with temozolomide and capecitabine has recently demonstrated an unprecedented prolongation of progression-free survival in a randomized trial of pNETs. Multiple retrospective series have reported the efficacy of liver-directed therapies both for palliating symptoms of hormone excess and for controlling tumor growth. Telotristat, an oral inhibitor of tryptophan hydroxylase, has been shown to reduce diarrhea in patients with carcinoid syndrome. Defining the therapeutic algorithm and identifying biomarkers predictive of response to treatments are among the main priorities for the next decade of research in the NET field. PMID- 30295931 TI - Feasibility study of combined dynamic imaging and lymphaticovenous anastomosis surgery for breast cancer-related lymphoedema. AB - BACKGROUND: Breast cancer-related lymphoedema (BCRL) presents a significant healthcare burden and adversely affects quality of life of breast cancer survivors. A prospective feasibility study was performed on lymphaticovenous anastomosis (LVA) for the treatment of BCRL. METHODS: Patients with BCRL underwent near-infrared spectroscopy with indocyanine green lymphatic mapping to identify suitable lymphatic channels for LVA. End-to-end anastomoses to subdermal venules were performed and patients recommenced compression garment therapy (CGT) after surgery. Volumetric assessment of the affected limb was performed at regular intervals using infrared perometry to calculate the excess volume reduction. RESULTS: Over a 24-month interval, 27 patients with BCRL underwent LVA. The mean duration of lymphoedema was 3.5 (range 0.5-18) years, and the mean number of LVAs performed was 3 (range 2-5). Twenty-four of the 27 patients completed 12-month follow-up. Patients exhibited three patterns of volumetric response following LVA: sustained response (16 patients), transient response (5) or no response (6). Sustained responders showed an excess volume reduction of 33.2 per cent at 12 months, and this correlated positively with the number of LVAs performed (r = -0.56, P = 0.034). Overall, ten patients were able to downgrade CGT after surgery, and two patients were CGT-free at 12 months. CONCLUSION: LVA resulted in a sustained volume reduction in selected patients and may offset the burden of CGT. Further work is required to identify biomarkers that predict a favourable response to LVA surgery. PMID- 30295932 TI - Effect of marital relationship on women's quality of life: Testing the mediating role of subjective well-being. AB - Because of a large number of Chinese women and the widespread concern about women's living conditions, this study aimed to examine how subjective well-being mediates the association between marital relationship and women's quality of life in Chinese context. The data used in this study were collected by conducting a multi-stage cluster random sampling method of 756 women in Huai'an city of Mainland China. Data included women's basic demographics, women's quality of life and marital quality, and women's subjective well-being. Structural equation modeling was adopted to analyze the data. The results of structural equation modeling analysis suggested a good fit for the sample. Overall findings showed that marital relationship has a significantly direct effect on women's quality of life, and subjective well-being can partially mediate the impact of marital relationship on women's quality of life. The implications on theory and social policy were also discussed. PMID- 30295933 TI - Hereditary transthyretin-related amyloidosis. AB - Hereditary transthyretin(TTR)-related amyloidosis (ATTRm amyloidosis) is an endemic/non-endemic, autosomal-dominant, early- and late-onset, rare, progressive disorder, predominantly manifesting as length-dependent, small fiber dominant, axonal polyneuropathy and frequently associated with cardiac disorders and other multisystem diseases. ATTRm amyloidosis is due to variants in the TTR gene, with the substitution Val30Met as the most frequent mutation. TTR mutations lead to destabilization and dissociation of TTR tetramers into variant TTR monomers, and formation of amyloid fibrils, which are consecutively deposited extracellularly in various tissues, such as nerves, heart, brain, eyes, intestines, kidneys, or the skin. Neuropathy may not only include large nerve fibers but also small fibers, and not only sensory and motor fibers but also autonomic fibers. Types of TTR variants, age at onset, penetrance, and clinical presentation vary between geographical areas. Suggestive of a ATTRm amyloidosis are a sensorimotor polyneuropathy, positive family history, autonomic dysfunction, cardiomyopathy, carpal tunnel syndrome, unexplained weight loss, and resistance to immunotherapy. If only sensory A-delta or C fibers are affected, small fiber neuropathy ensues. Diagnostic tests for small fiber neuropathy include determination of intraepidermal nerve fiber density, laser-evoked potentials, heat- and cold detection thresholds, and measurement of the electrochemical skin conductance. Therapy currently relies on liver transplantation and TTR-stabilizers (tafamidis, diflunisal).

PMID- 30295937 TI - The RNA editing factor DUA1 is crucial to chloroplast development at low temperature in rice. AB - Low temperature stress hinders plant growth and chloroplast development and can limit the geographic range of cultivars. In rice, japonica cultivars have greater chilling tolerance than indica cultivars, but the molecular mechanism underlying chilling tolerance is unclear. Here, we report an RNA-binding protein, DUA1, cloned from the indica cultivar Dular, which exhibits a deficiency in chloroplast development at an early stage of development under low-temperature conditions. DUA1 shares high sequence homology with the pentatricopeptide repeat family and functions in plastid RNA editing under low-temperature conditions. Our data suggest that DUA1 can bind to the plastid-encoded rps8-182 transcript and disruption of DUA1 activity impairs editing. The RNA editing cofactor WSP1, a partner of DUA1, also participates in chloroplast development at low temperature. Western blot analysis indicates that WSP1 enhances DUA1 stability under low temperatures. DUA1 sequence analyses of rice core germplasm revealed that three major haplotypes of DUA1 and one haplotype showed substantial differences in chlorophyll content under low-temperature conditions. Variation at DUA1 may play an important role in the adaptation of rice to different growing regions.

AB - Species distribution is strongly driven by local and global gradients in water availability but the underlying mechanisms are not clear. Vulnerability to xylem embolism (P50 ) is a key trait that indicates how species cope with drought and might explain plant distribution patterns across environmental gradients. Here we address its role on species sorting along a hydro-topographical gradient in a central Amazonian rainforest and examine its variance at the community scale. We measured P50 for 28 tree species, soil properties and estimated the hydrological niche of each species using an indicator of distance to the water table (HAND). We found a large hydraulic diversity, covering as much as 44% of the global angiosperm variation in P50 . We show that P50 : contributes to species segregation across a hydro-topographic gradient in the Amazon, and thus to species coexistence; is the result of repeated evolutionary adaptation within closely related taxa; is associated with species tolerance to P-poor soils, suggesting the evolution of a stress-tolerance syndrome to nutrients and drought; and is higher for trees in the valleys than uplands. The large observed hydraulic diversity and its association with topography has important implications for modelling and predicting forest and species resilience to climate change.

AB - In primates, resting state functional neuroimaging (rsfcMRI) has identified several large-scale, intrinsic brain networks, including the salience network (SN), which is involved in detecting stimulus salience. Intranasal oxytocin (IN OT) has been shown to modulate the salience and rewarding quality of social stimuli in mammals and numerous studies have shown that it can affect the functional connectivity between brain regions. Less is known, however, about how these effects unfold over time following IN-OT administration. This study used rsfcMRI in anesthetized rhesus macaques to track temporal changes in the functional connectivity between brain regions involved in the SN, including the anterior cingulate cortex (ACC), anterior insula (AI), amygdala (amy), and ventral striatum (vstr), lasting 3 hr after IN-OT or Placebo (saline) administration. We found significant temporal changes in the functional connectivity between all regions associated with treatment condition. IN-OT increased the functional connectivity between AI_vstr, ACC_amy (right hemisphere), ACC_vstr (left hemisphere), and amy_vstr (right hemisphere), but reduced the functional connectivity between ACC_AI, and the AI_amygdala. These results suggest that IN-OT may dampen salience detection in rhesus monkeys, consistent with previous findings of reduced social vigilance, while enhancing the connectivity between the SN and regions involved in processing reward. PMID- 30295945 TI - Actinomycin-D and dimethylamino-parthenolide synergism in treating human pancreatic cancer cells. AB - Preclinical Research & Development Pancreatic cancer is the third leading cause of death in the US with a poor 5-year survival rate of 8.5%. A novel anti-cancer drug, dimethylamino parthenolide (DMAPT), is the water-soluble analog of the natural sesquiterpene lactone, parthenolide. The putative modes of action of DMAPT are inhibition of the Nuclear chain factor kappa-light-chain enhancer of activated B cells (NFkappaB) pathway and depletion of glutathione levels; the latter causing cancer cells to be more susceptible to oxidative stress-induced cell death. Actinomycin-D (ActD) is a polypeptide antibiotic that binds to DNA, and inhibits RNA and protein synthesis by inhibiting RNA polymerase II. A phase 2 clinical trial indicated that ActD could be a potent drug against pancreatic cancer; however, it was not a favored drug due to toxicity issues. New drug entities and methods of drug delivery, used alone or in combination, are needed to treat pancreatic cancer more effectively. Thus, it was postulated that combining DMAPT and ActD would result in synergistic inhibition of Panc-1 pancreatic cancer cell growth because DMAPT's inhibition of NFkappaB would enhance induction of apoptosis by ActD, via phosphorylation of c-Jun, by minimizing NFkappaB inhibition of c-Jun phosphorylation. Combining these two drugs induced a higher level of cell death than each drug alone. A fixed drug ratio of DMAPT: ActD (1,200:1) was used. Data from metabolic (MTT) and colony formation assays were analyzed for synergism with CompuSyn software, which utilizes the Chou-Talalay equation. The analyses indicated synergism and moderate synergism at combination concentrations of DMAPT/ActD of 12/0.01 and 18/0.015 MUM, respectively. PMID- 30295947 TI - Micro-CT analysis of danger zone thickness in the mesiobuccal roots of maxillary first molars. AB - AIM: To evaluate dentine thickness from both distal ('danger zone') and mesial ('safety zone') aspects of the MB1 and MB2 canals of maxillary first molars at the furcation level using micro-CT imaging. METHODOLOGY: One hundred maxillary first molars with two canals in the MB root were selected from a Brazilian subpopulation and scanned at a resolution of 19.6 MUm in a micro-CT device. From each specimen, two axial cross-sectioned images were selected at 2 and 3 mm apical to the furcation level of the MB root and evaluated for the smallest dentinal thickness. Measurements were made from the outer perimeter of the MB1 and MB2 canals towards the external root surface from both distal (danger zone) and mesial (safety zone) aspects of the root. The influence of an isthmus was also considered in the analysis, and samples were classified according to the presence or absence of an isthmus in the axial sections. Non-parametric Wilcoxon signed-rank tests were used to compare dentinal thickness between MB1 and MB2 canals with a significant level set at 5%. Colour-coded 3D models of dentine thickness throughout the MB root were created and evaluated qualitatively. RESULTS: At both levels, median dentine thickness of the MB2 canal was significantly lower in both distal and mesial aspects of the root in comparison with the MB1 canal (P < 0.01). The presence of an isthmus was not a variable that influenced dentinal thickness. Colour-coded models indicated that dentine thickness was dependent on the cross-sectional shape of the MB root. At least 50% of the sample had <1 mm of dentine thickness at the danger zone of the MB2 canal. CONCLUSIONS: Danger zones in the MB roots of maxillary first molars were not symmetrical. MB2 canals had less dentine thickness on both aspects of the root compared to the MB1 canal. PMID- 30295948 TI - Liver fat scores predict liver disease mortality in the United States population. AB - BACKGROUND: Fatty liver is a significant global public health burden, contributing to premature death. AIM: To examine whether liver fat scores were associated with increased overall and disease-specific mortality in a United States (US) population-based survey with up to 27 years of linked mortality data. METHODS: We studied 9200 fasted viral hepatitis-negative adults in the third National Health and Nutrition Examination Survey, 1988-1994. Liver fat was predicted using the US fatty liver index (US FLI), fatty liver index (FLI), non alcoholic fatty liver disease liver fat score (NAFLD LFS), and hepatic steatosis index (HSI). Participants were passively followed up for mortality, identified by death certificate underlying or contributing causes, by linkage to National Death Index records through 2015. Mortality hazard ratios (HR) were calculated using Cox proportional hazards regression to adjust for mortality risk factors. RESULTS: During follow-up (median, 23.3 years), cumulative mortality was 31.4% overall and 1.1% with liver disease, including primary liver cancer. Elevated liver disease mortality was associated with a high US FLI (HR, 5.7; 95% confidence interval (CI), 1.3-24.5), and intermediate (HR, 3.1; 95% CI, 1.1-9.1) or high (HR, 11.4; 95% CI, 2.9-44.4) NAFLD LFS, but not with a higher FLI or HSI. Overall and cardiovascular disease mortality was unassociated with higher liver fat scores. CONCLUSIONS: In the US population, a higher US FLI and NAFLD LFS were associated with increased liver disease mortality, but not with other mortality outcomes. Liver fat scores may be useful for metabolic health surveillance and long-term liver disease risk stratification and may complement fibrosis markers for tracking. PMID- 30295949 TI - Feasibility of photon beam profile deconvolution using a neural network. AB - PURPOSE: Ionization chambers are the detectors of choice for photon beam profile scanning. However, they introduce significant volume averaging effect (VAE) that can artificially broaden the penumbra width by 2-3 mm. The purpose of this study was to examine the feasibility of photon beam profile deconvolution (the elimination of VAE from ionization chamber-measured beam profiles) using a three layer feedforward neural network. METHODS: Transverse beam profiles of photon fields between 2 * 2 and 10 * 10 cm2 were collected with both a CC13 ionization chamber and an EDGE diode detector on an Elekta Versa HD accelerator. These profiles were divided into three datasets (training, validation and test) to train and test a three-layer feedforward neural network. A sliding window was used to extract input data from the CC13-measured profiles. The neural network produced the deconvolved value at the center of the sliding window. The full deconvolved profile was obtained after the sliding window was moved over the measured profile from end to end. The EDGE-measured beam profiles were used as reference for the training, validation, and test. The number of input neurons, which equals the sliding window width, and the number of hidden neurons were optimized with a parametric sweeping method. A total of 135 neural networks were fully trained with the Levenberg-Marquardt backpropagation algorithm. The one with the best overall performance on the training and validation dataset was selected to test its generalization ability on the test dataset. The agreement between the neural network-deconvolved profiles and the EDGE-measured profiles was evaluated with two metrics: mean squared error (MSE) and penumbra width difference (PWD). RESULTS: Based on the two-dimensional MSE plots, the optimal combination of sliding window width of 15 and 5 hidden neurons was selected for the final neural network. Excellent agreement was achieved between the neural network-deconvolved profiles and the reference profiles in all three datasets. After deconvolution, the mean PWD reduced from 2.43 +/- 0.26, 2.44 +/- 0.36, and 2.46 +/- 0.29 mm to 0.15 +/- 0.15, 0.04 +/- 0.03, and 0.14 +/- 0.09 mm for the training, validation, and test dataset, respectively. CONCLUSIONS: We demonstrated the feasibility of photon beam profile deconvolution with a feedforward neural network in this work. The beam profiles deconvolved with a three-layer neural network had excellent agreement with diode-measured profiles. PMID- 30295950 TI - Validation and application of a fast Monte Carlo algorithm for assessing the clinical impact of approximations in analytical dose calculations for pencil beam scanning proton therapy. AB - PURPOSE: Monte Carlo (MC) dose calculation is generally superior to analytical dose calculation (ADC) used in commercial TPS to model the dose distribution especially for heterogeneous sites, such as lung and head/neck patients. The purpose of this study was to provide a validated, fast, and open-source MC code, MCsquare, to assess the impact of approximations in ADC on clinical pencil beam scanning (PBS) plans covering various sites. METHODS: First, MCsquare was validated using tissue-mimicking IROC lung phantom measurements as well as benchmarked with the general purpose Monte Carlo TOPAS for patient dose calculation. Then a comparative analysis between MCsquare and ADC was performed for a total of 50 patients with 10 patients per site (including liver, pelvis, brain, head-and-neck, and lung). Differences among TOPAS, MCsquare, and ADC were evaluated using four dosimetric indices based on the dose-volume histogram (target Dmean, D95, homogeneity index, V95), a 3D gamma index analysis (using 3%/3 mm criteria), and estimations of tumor control probability (TCP). RESULTS: Comparison between MCsquare and TOPAS showed less than 1.8% difference for all of the dosimetric indices/TCP values and resulted in a 3D gamma index passing rate for voxels within the target in excess of 99%. When comparing ADC and MCsquare, the variances of all the indices were found to increase as the degree of tissue heterogeneity increased. In the case of lung, the D95s for ADC were found to differ by as much as 6.5% from the corresponding MCsquare statistic. The median gamma index passing rate for voxels within the target volume decreased from 99.3% for liver to 75.8% for lung. Resulting TCP differences can be large for lung (<=10.5%) and head-and-neck (<=6.2%), while smaller for brain, pelvis and liver (<=1.5%). CONCLUSIONS: Given the differences found in the analysis, accurate dose calculation algorithms such as Monte Carlo simulations are needed for proton therapy, especially for disease sites with high heterogeneity, such as head-and neck and lung. The establishment of MCsquare can facilitate patient plan reviews at any institution and can potentially provide unbiased comparison in clinical trials given its accuracy, speed and open-source availability. PMID- 30295951 TI - Estimating onset time from longitudinal data in the presence of measurement error with application to estimating gestational age from maternal anthropometry during pregnancy. AB - Accurate assessment of gestational age at birth is necessary for optimal pediatric care. In high resource countries, several methods using ultrasound have been proposed to assess gestational age at birth; however, these methods are not easily accessible for low-resource populations. We develop a shared random parameter model for estimating gestational age at birth from longitudinal maternal anthropometry that incorporates additional maternal information from the last menstrual period, a measure of gestational age collected with sizable measurement error. The proposed methodology is evaluated using simulation studies under a training-test set paradigm. In addition, we propose methodology to validate prediction when some measurements of the gold standard are collected with measurement error. We illustrate the proposed methodologies with data from the NICHD Fetal Growth Studies. PMID- 30295952 TI - Associations of tumor necrosis factor-alpha polymorphisms with the risk of tuberculosis: a meta-analysis. AB - Recently, the roles of tumor necrosis factor-alpha (TNF-alpha) polymorphisms in tuberculosis (TB) were intensively analyzed, but the results of these studies were inconsistent. Therefore, we performed this study to better assess the relationship between TNF-alpha polymorphisms and the risk of TB. Eligible studies were searched in PubMed, Medline, Embase and CNKI. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess correlations between TNF-alpha polymorphisms and TB. A total of 31 studies were included for analyses. Significant associations with the risk of TB were detected for TNF-alpha -308 G/A and -857 C/T polymorphisms in overall analyses. Further subgroup analyses based on ethnicity of participants revealed that TNF-alpha -238 G/A, -308 G/A, -857 C/T and -863 C/A polymorphisms were all significantly associated with the risk of TB in East Asians. When we stratified available data according to type of disease, we found that TNF-alpha -238 G/A and -308 G/A polymorphisms were significantly correlated with the risk of extrapulmonary tuberculosis (EPTB), while the -857 C/T polymorphism was significantly correlated with the risk of pulmonary tuberculosis (PTB). In conclusion, our findings indicated that TNF-alpha -238 G/A, -308 G/A, -857 C/T and -863 C/A polymorphisms may serve as potential biological markers for TB in East Asians.

PMID- 30295953 TI - Multistate modeling and simulation of patient trajectories after allogeneic hematopoietic stem cell transplantation to inform drug development. AB - We present a case study for developing clinical trial scenarios in a complex progressive disease with multiple events of interest. The idea is to first capture the course of the disease in a multistate Markov model, and then to simulate clinical trials from this model, including a variety of hypothesized drug effects. This case study focuses on the prevention of graft-versus-host disease (GvHD) after allogeneic hematopoietic stem cell transplantation (HSCT). The patient trajectory after HSCT is characterized by a complex interplay of various events of interest, and there is no established best method of measuring and/or analyzing treatment benefits. We characterized patient trajectories by means of multistate models that we fitted to a subset of the Center for International Blood and Marrow Transplant Research (CIBMTR) database. Events of interest included acute GvHD of grade III or IV, severe chronic GvHD, relapse of the underlying disease, and death. The transition probability matrix was estimated using the Aalen-Johansen estimator, and patient characteristics were identified that were associated with different transition rates. In a second step, clinical trial scenarios were simulated from the model assuming various drug effects on the background transition rates, and the operating characteristics of different endpoints and analysis strategies were compared in these scenarios. This helped devise a drug development strategy in GvHD prevention after allogeneic HSCT. More generally, multistate models provide a rich framework for exploring complex progressive diseases, and the availability of a corresponding simulation machinery provides great flexibility for clinical trial planning. PMID- 30295954 TI - Measuring national resilience: A new short version of the scale (NR-13). AB - This article is aimed at describing and validating a new short version of the National Resilience Scale (NR-13). The available 25-item National Resilience Scale has been employed and validated by several studies. However, the present data show that it can be substantially shortened without losing either its reliability or its validity. The new short version of the scale has been examined by the responses of an Israeli sample of adults (N = 1022). Results indicate, as expected, that national resilience promoting factors (community resilience and sense of coherence) significantly and positively predict NR-13. A resilience suppressing factor (sense of danger) negatively and significantly predicts NR-13. These predictions have been replicated in an additional sample of Israeli higher education students (N = 423). These results support the reliability and the validity of the short National Resilience Scale (NR-13). PMID- 30295955 TI - Autocalibrated multiband CAIPIRINHA with through-time encoding: Proof of principle and application to cardiac tissue phase mapping. AB - PURPOSE: In conventional multiband (MB) CAIPIRINHA, additional reference scans are acquired to allow the separation of the excited slices. In this study, an acquisition-reconstruction technique that makes use of the MB data to calculate these reference data is presented. The method was integrated into a 2D time resolved phase-contrast MR sequence used to assess velocities of the myocardium. METHODS: The RF phases of the MB pulse are cycled through time so that consecutive cardiac phases can be grouped to form reference scans at a lower temporal resolution. These reference data are subsequently used to separate the original slices at the original, high temporal resolution using slice/split-slice GRAPPA algorithms. Slice separation performances are evaluated and compared with conventional methods at 3 T, and 3 different strategies for the calibration of the kernels are proposed and compared. Finally, 6 subjects were scanned to assess velocities of the myocardium. RESULTS: Because the acquisition of external references is not needed, no additional breath-holds are required and the full MB acceleration could be exploited. Because the reference and MB data have the same resolution and phase structure, better slice separation was achieved when comparing the proposed technique to conventional workflows. Finally, time resolved velocities of the myocardial tissue were successfully quantified from MB data, showing good agreement with single-band measurements. CONCLUSION: Our built in reference method allows the full exploitation of the MB acceleration and it limits the number of breath-holds. PMID- 30295956 TI - Reactive oxygen species stimulated pulmonary epithelial cells mediate the alveolar recruitment of FasL+ killer B cells in LPS-induced acute lung injuries. AB - Reactive oxygen species (ROS) are electrophilic chemical species produced from incomplete oxidation. They have long been known as aggressive molecules that lead to direct tissue and cellular damage. Recent studies have reconsidered ROS as second messengers in the initiation and amplification of cell signaling, but how ROS regulate lung tissue and immune cell remain unknown. In this study, we used a LPS-induced acute lung injury (ALI) mouse model to observe disease, progression and determine ROS-related immune responses. We found that ROS play an essential pathogenic role in ALI, however, the major role of ROS in exacerbating ALI was increasing bronchoalveolar fluid (BALF) B cells rather than eliciting tissue damage. Moreover, these pathogenic B cells are FasL+ killer B cells, which reported to damage Fas-sensitive target cells including pulmonary epithelial cells. Furthermore, via in vitro transwell assays and in vivo treatment with neutralizing antibodies. ROS promoted pulmonary epithelial cells to produce CXCL9 and CXCL10, which recruited B cells into BALF. These results demonstrated that during lung injury, instead of causing oxidative damage, ROS mainly serve as second messengers, interacting with tissue and immune cells to enhance immune responses that lead to more severe disease. PMID- 30295957 TI - Visible-Light-Responsive 2D Cadmium-Organic Framework Single Crystals with Dual Functions of Water Reduction and Oxidation. AB - The development of new metal-organic frameworks (MOFs) with dual functions of both water reduction and oxidation under visible-light irradiation is highly desirable for promising solar water splitting, but is not yet reported. Herein, a cadmium-based MOF (denoted as "Cd-TBAPy") single crystal with a 2D layered framework by employing 1,3,6,8-tetrakis(p-benzoic acid)pyrene (H4 TBAPy) as an organic linker is reported, which exhibits good visible-light absorption with edge of ~600 nm. The Mott-Schottky (M-S) measurement and UV-vis analysis integrally reveal that the Cd-TBAPy is an n-type semiconductor with a bandgap of ~2.15 eV whose conduction and valence band are estimated to be -0.05 and 2.10 eV, respectively. Together with loading of Pt or CoPi cocatalyst, the Cd-TBAPy is active for both water reduction and oxidation in the presence of scavengers under visible-light irradiation. Especially, the optimized apparent quantum efficiency for O2 evolution reaches 5.6% at 420 nm, much higher than that of previous MOF based photocatalysts reported so far. This is thought to be the first MOF that functions as a photocatalyst for both water reduction and oxidation under visible light, demonstrating the intriguing future of MOF materials in solar-to-chemical energy conversion. PMID- 30295958 TI - The miRNA biogenesis pathway prevents inappropriate expression of injury response genes in developing and adult Schwann cells. AB - Proper function of the nervous system depends on myelination. In peripheral nerves, Schwann cells (SCs) myelinate axons and the miRNA biogenesis pathway is required for developmental myelination and myelin maintenance. However, regulatory roles of this pathway at different stages of myelination are only partially understood. We addressed the requirement of the core miRNA biogenesis pathway components Dgcr8, Drosha, and Dicer in developing and adult SCs using mouse mutants with a comparative genetics and transcriptomics approach. We found that the microprocessor components Dgcr8 and Drosha are crucial for axonal radial sorting and to establish correct SC numbers upon myelination. Transcriptome analyses revealed a requirement of the microprocessor to prevent aberrantly increased expression of injury-response genes. Those genes are predicted targets of abundant miRNAs in sciatic nerves (SNs) during developmental myelination. In agreement, Dgcr8 and Dicer are required for proper maintenance of the myelinated SC state, where abundant miRNAs in adult SNs are predicted to target injury response genes. We conclude that the miRNA biogenesis pathway in SCs is crucial for preventing inappropriate activity of injury-response genes in developing and adult SCs.

PMID- 30295961 TI - Attitudes and Responses of Medical Students and Professional Anatomists to Dissecting Different Regions of the Body. AB - Although there have been many studies assessing emotional responses of medical students to the dissecting room experience, little is known about whether dissecting particular regions of the human body cause more concern than others. Furthermore, no studies have been conducted on the concerns of professional anatomists. In this study, we assessed the hypothesis that medical students are more concerned about the dissection of the face, the perineum and the extremities of the limbs. We also hypothesized that there are gender differences. For the reactions of a group of professional anatomists from the United States and Europe we hypothesized that they were less concerned than the medical students and showed no differences across the regions of the body. The hypotheses were tested by means of questionnaires distributed to medical students at Cardiff University and at the Descartes Paris University who had recently completed their anatomy courses and to anatomists working at universities in Europe and the USA. Ethical approval for the study was obtained from the ethical committees at the Cardiff School of Biosciences and at Paris and all data was obtained by consent of the respondents and remained confidential. The findings were complex, although the level of concern was low overall. Some regional differences were discerned, particularly concerning the face, the perineum, the hand and the female chest. Anatomists were less concerned than the students and female students and female anatomists showed more concern than their male counterparts. Few differences were discerned however between student respondents who had positive and neutral attitudes to gender "politics" and those who espoused negative views. We recommend that, at the start of an anatomy dissection course, time is spent dealing with sensitive issues (including equality and diversity issues), emotional responses, and matters pertaining to mortality. However, we argue that this should not involve hiding regions of the body, nor overreacting to the natural anxiety of students, since doing either of these things could enhance negative reactions and stifle the progress of the student from being a layperson to a competent healthcare professional.

PMID- 30295963 TI - A quantitative structure-property relationship (QSPR) for estimating solid material-air partition coefficients of organic compounds. AB - The material-air partition coefficient (Kma ) is a key parameter to estimate the release of chemicals incorporated in solid materials and resulting human exposures. Existing correlations to estimate Kma are applicable for a limited number of chemical-material combinations without considering the effect of temperature. The present study develops a quantitative structure-property relationship (QSPR) to predict Kma for a large number of chemical-material combinations. We compiled a dataset of 991 measured Kma for 179 chemicals in 22 consolidated material types. A multiple linear regression model predicts Kma as a function of chemical's Koa , enthalpy of vaporization (?Hv ), temperature, and material type. The model shows good fitting of the experimental dataset with adjusted R2 of 0.93 and has been verified by internal and external validations to be robust, stable and has good predicting ability ( Rext2 > 0.78). A generic QSPR is also developed to predict Kma from chemical properties and temperature only (adjusted R2 = 0.84), without the need to assign a specific material type. These QSPRs provide correlation methods to estimate Kma for a wide range of organic chemicals and materials, which will facilitate high-throughput estimates of human exposures for chemicals in solid materials, particularly building materials and furniture. PMID- 30295962 TI - Epithelial to mesenchymal transition is involved in ethanol promoted hepatocellular carcinoma cells metastasis and stemness. AB - Hepatocellular Carcinoma (HCC) is a malignant tumor with high rate of relapse and metastasis. Ethanol is a well-known risk factor for HCC; it promotes the progression and aggressiveness of HCC. However, the underlying mechanism remains unclear. In clinic studies, we showed that alcohol consumption is positively correlated with TNM stage and vessel invasion; HCC patients with chronic drinking history had faster progression rate and poorer prognosis compared to non drinkers. In experimental models, ethanol exposure enhanced the metastasis, and invasion of HCC cells. Ethanol exposure increased cancer stem cells (CSC) population and enhanced stemness of HCC cells in vitro and in vivo. Mechanically, we found that ethanol exposure induced epithelial to mesenchymal transition (EMT) through activating Wnt/beta-catenin signaling pathway in HCC cells. We further demonstrated that beta-catenin siRNA or salinomycin (an inhibitor of Wnt/beta catenin pathway) partially rescued ethanol-induced EMT. In conclusion, this study suggested that ethanol exposure promotes the metastasis and stemness of HCC cells by inducing EMT. PMID- 30295964 TI - Estradiol-regulated innate antiviral responses of human endometrial stromal fibroblasts. AB - PROBLEM: The contribution of fibroblasts to innate immune protection of the human female reproductive tract (FRT) against viral pathogens is relatively unknown. METHOD OF STUDY: Endometrial (EM), endocervical (Cx) and ectocervical (ECx) fibroblasts were isolated from hysterectomy patients and grown in vitro. Fibroblasts were treated with the viral mimic poly (I:C) in the presence or absence of the sex hormone estradiol (E2 ), with gene expression measured by real time RT-PCR and protein secretion by ELISA. RESULTS: Poly (I:C) induced the expression of the interferon-stimulated genes (ISG) MxA, OAS2 and APOBEC3G, and the cytokines MCP-1, IL-8, IL-6, CCL20, IFNbeta and RANTES by fibroblasts from all three sites. ISG upregulation was dependent upon Type I IFN signaling. E2 inhibited the poly (I:C)-induced upregulation of MxA and OAS2 in EM fibroblasts, but not Cx or ECx fibroblasts. E2 upregulated SDF-1alpha by EM fibroblasts but had no effect on secretion of other cytokines either alone or in the presence of poly (I:C). Conditioned media (CM) from poly (I:C)-treated or E2 -treated fibroblasts significantly reduced HIV infection of CD4+ T cells. CONCLUSION: Stromal fibroblasts represent a level of innate immune protection against viral pathogens in the FRT beyond that seen with epithelial cells and immune cells. Our findings indicate that fibroblasts FRT are selectively responsive to E2 , capable of initiating an antiviral response against viral pathogens and may play a role in preventing HIV infection of CD4+ T cells.

Sleep causes reduced responsiveness to the environment, which puts animals in a particularly vulnerable state; yet sleep has been conserved throughout evolution, indicating that it fulfils a vital purpose. A core function of sleep across species has not been identified, but substantial advances in sleep research have been made in recent years using the genetically tractable model organism, Drosophila melanogaster. This review describes the universality of sleep, the regulation of sleep, and current theories on the function of sleep, highlighting a historical and often overlooked theory called the Free Radical Flux Theory of Sleep. Additionally, we summarize our recent work with short-sleeping Drosophila mutants and other genetic and pharmacological tools for manipulating sleep which supports an antioxidant theory of sleep and demonstrates a bi-directional relationship between sleep and oxidative stress.

AB - BACKGROUND: Listeria monocytogenes (LM) is an important foodborne pathogen affecting animals and humans. Listeriosis outbreaks in humans caused by consumption of unpasteurized dairy products are of serious concern. OBJECTIVE: To determine risk factors associated with fecal shedding of LM in family dairy farms. ANIMALS: Fecal samples were collected from cows and calves on 20 family dairy farms in 2-week intervals for a period of 1 year. METHODS: Longitudinal study. LM was detected using qPCR. Univariate mixed effect model and multivariate analyses were performed to associate risk factors (dietary change, breed, mastitis, other diseases, antibiotic treatment, other treatments, heat index, and meteorological season) with fecal shedding of LM. RESULTS: LM was isolated from all farms on at least 1 sampling day. The average yearly prevalence was 18.2% (98/540) and 8.4% (43/511) in cows and calves, respectively. Heat index (P = .05) and meteorological season (P = .04) affected fecal shedding of LM on a farm level. Meteorological season only influenced fecal shedding of LM in cows (P = .04), whereas heat index (P = .01) influenced fecal shedding of LM in calves. Spring season was identified as the major risk factor associated fecal shedding of LM on a farm level (P = .01) and in cows (P = .01). Dietary changes were associated with lower odds for fecal shedding of LM in calves (P < .01). CONCLUSIONS AND CLINICAL IMPORTANCE: Fecal shedding of LM is associated with environmental temperatures and the meteorological season. Farmers and veterinarians should use this information when implementing strategies to reduce risks for LM dissemination in animals and in the community.

AB - The sensitive detection of X-rays embodies an important research area, being motivated by a common desire to minimize the radiation doses required for detection. Among metal halide perovskites, the double-perovskite Cs2 AgBiBr6 system has emerged as a promising candidate for the detection of X-rays, capable of high X-ray stability and sensitivity (105 MUC Gy-1 cm-2 ). Herein, the important photophysical pathways in single-crystal Cs2 AgBiBr6 are detailed at both room (RT) and liquid-nitrogen (LN2 T) temperatures, with emphasis made toward understanding the carrier dynamics that influence X-ray sensitivity. This study draws upon several optical probes and an RT excitation model is developed which is far from optimal, being plagued by a large trap density and fast free carrier recombination pathways. Substantially improved operating conditions are revealed at 77 K, with a long fundamental carrier lifetime (>1.5 us) and a marked depopulation of parasitic recombination pathways. The temperature dependence of a single-crystal Cs2 AgBiBr6 X-ray detecting device is characterized and a strong and monotonic enhancement to the X-ray sensitivity upon cooling is demonstrated, moving from 316 MUC Gy-1 cm-2 at RT to 988 MUC Gy-1 cm-2 near LN2 T. It is concluded that even modest cooling-via a Peltier device-will facilitate a substantial enhancement in device performance, ultimately lowering the radiation doses required. PMID- 30295969 TI - FIP4/Arfophilin-2 plays overlapping but distinct roles from FIP3/Arfophilin-1 in neuronal migration during cortical layer formation. AB - The class II Rab11 family-interacting proteins, FIP3 and FIP4, also termed Arfophilin-1 and Arfophilin-2, respectively, are endosomal proteins that function as dual effector proteins for Rab11 and ADP ribosylation factor (Arf) small GTPases. In the present study, we examined the expression and role of FIP4 in neuronal migration during cerebral layer formation. FIP4 mRNA was first weakly detected in post-mitotic migrating neurons in the upper intermediate zone, and expression was markedly increased in the cortical layer. Exogenously expressed FIP4 protein was localized to subpopulations of EEA1- and syntaxin 12-positive endosomes in migrating neurons, and was partially colocalized with FIP3. Knockdown of FIP4 by in utero electroporation significantly stalled transfected neurons in the lower cortical layer and decreased the speed of neuronal migration in the upper intermediate zone and in the cortical plate compared with control small hairpin RNA (shRNA)-transfected neurons. Furthermore, co-transfection of shRNA-resistant wild-type FIP4, but not wild type FIP3 or FIP4 mutants lacking the binding region for Rab11 or Arf, significantly improved the disturbed cortical layer formation caused by FIP4 knockdown. Collectively, our findings suggest that FIP4 and FIP3 play overlapping but distinct roles in neuronal migration downstream of Arf and Rab11 during cortical layer formation. PMID- 30295968 TI - Efficient access to both enantiomers of 3-(1-hydroxyethyl)phenol by regioselective and enantioselective CAL-B-catalyzed hydrolysis of diacetate in organic media by sodium carbonate. AB - In the present paper, we describe several pathways employing immobilized lipase from Candida antarctica B (CAL-B) as biocatalyst to prepare easily both enantiomers of 3-(1-hydroxyethyl)phenol. We have applied hydrolysis with Na2 CO3 in organic media under mild conditions. The reaction parameters solvent effect, amount of lipase, and Na2 CO3 were examined with 3-(1-acetoxyethyl)phenyl acetate as substrate. In alkaline hydrolysis, (R)-3-(1-hydroxyethyl)phenol was obtained with ee = 99% and (S)-(-)-3-(1-acetoxyethyl)phenol with ee = 98% at optimal conversion (c = 50%) and high selectivity (E > 200). Two other deacylation reactions were compared: alcoholysis with MeOH and with NEt3 . The acylation of 3 (1-hydroxyethyl)phenol with vinyl acetate was also examined. Alkaline hydrolysis gave the best results, while good regioselectivity and enantioselectivity were observed in alcoholysis and acylation reactions. Finally, (S)- and (R)-3-(1 hydroxyethyl)phenol (ee > 98%), key intermediates for the synthesis of important drugs, were prepared from the corresponding racemic diacetate through alkaline hydrolysis. PMID- 30295970 TI - Work pattern of neurology nurses in a Chinese hospital: A time and motion study. AB - AIM: To investigate nursing work patterns in a neurology department in a Chinese hospital. BACKGROUND: Knowledge of nursing work patterns is important for nursing management and work design, and for the evaluation of organizational process change associated with the introduction of an innovation. METHODS: A time-and motion method was used to observe 14 registered nurses' (RNs') work patterns in a neurology department in a Chinese hospital. RESULTS: There were 147 hr of observation. Overall, the most time-consuming activities were verbal communication (28.5%) and documentation (28.3%), followed by indirect care (14.6%) and direct care (14%). Compared to support RNs, charge RNs spent 20% more time on documentation and 11% more time on verbal communication. Two-thirds of the observed activities had a duration of less than 40 s. CONCLUSIONS: Communication, in verbal and written forms, consumed more than half of the nursing time. Conversely, nurses only spent about a quarter of their worktime on preparation for care provision and direct care provision. This reflects the significant role and resource-consuming nature of communication to provide safe and quality care. IMPLICATIONS FOR NURSING MANAGEMENT: Communication methods need to be enhanced to improve nursing productivity. This may be achieved through the introduction of more effective nursing documentation methods. PMID- 30295971 TI - Accessory tricuspid leaflet associated with persistent left superior vena cava. AB - Right atrioventricular valve is historically named as tricuspid valve. However, cases depicting multi-leaflet morphology of the right atrioventricular valve were reported. Accessory leaflet of the tricuspid valve is a rare entity and associated with congenital cardiac anomalies. We present an accessory tricuspid valve in a patient with isolated persistent left superior vena cava. PMID- 30295972 TI - Speckle tracking echocardiography and right ventricle dysfunction in acute respiratory distress syndrome a pilot study. AB - PURPOSE: Speckle tracking echocardiography is a novel echocardiographic technique to assess RV myocardial function but no data are so far available in patients with acute respiratory distress syndrome (ARDS), and we aimed at assessing the feasibility of 2 dimensional (2D) speckle tracking echocardiography and the prognostic role of RV free wall speckle tracking strain in 30 consecutive patients with moderate-severe ARDS MATERIALS AND METHODS: In an observational prospective study, 30 consecutive patients with moderate-severe ARDS were enrolled. Echocardiography was performed within 12 hours from ICU admission. RESULTS: Mortality rate was 33% (10/30). Non-survivors showed lower values of pH (7.32 +/- 0.09, P = 0.03) and higher troponin I levels (0.32 (0.08-0.46), P = 0.04), NT-pro BNP (3091 (2662-7128), P = 0.009), and SAPS II (60.3 +/- 9.6, P < 0.001). At echocardiographic examination, non-survivors showed lower values of TAPSE (18.3 +/- 3, P = 0.034) and higher systolic pulmonary arterial pressure (49.6 +/- 16, P = 0.05). Two patients (6.6%) did not show valid acoustic windows. Only three patients showed normal values of RV strain free wall (22%, 25%, and 28% absolute values, respectively), among whom one patient died. When compared to survivors, non-survivors showed significantly lower values of RV strain free wall (-10.4 +/- 0.10, P < 0.001). CONCLUSIONS: In mechanically ventilated moderate severe ARDS, 2D speckle tracking is feasible even though difficult acoustic windows are common. Further studies are needed to confirm our findings in a larger cohort of patients. PMID- 30295974 TI - E3 ubiquitin ligases LNX1 and LNX2 localize at neuronal gap junctions formed by connexin36 in rodent brain and molecularly interact with connexin36. AB - Electrical synapses in the mammalian central nervous system (CNS) are increasingly recognized as highly complex structures for mediation of neuronal communication, both with respect to their capacity for dynamic short- and long term modification in efficacy of synaptic transmission and their multimolecular regulatory and structural components. These two characteristics are inextricably linked, such that understanding of mechanisms that contribute to electrical synaptic plasticity requires knowledge of the molecular composition of electrical synapses and the functions of proteins associated with these synapses. Here, we provide evidence that the key component of gap junctions that form the majority of electrical synapses in the mammalian CNS, namely connexin36 (Cx36), directly interacts with the related E3 ubiquitin ligase proteins Ligand of NUMB protein X1 (LNX1) and Ligand of NUMB protein X2 (LNX2). This is based on immunofluorescence colocalization of LNX1 and LNX2 with Cx36-containing gap junctions in adult mouse brain versus lack of such coassociation in LNX null mice, coimmunoprecipitation of LNX proteins with Cx36, and pull-down of Cx36 with the second PDZ domain of LNX1 and LNX2. Furthermore, cotransfection of cultured cells with Cx36 and E3 ubiquitin ligase-competent LNX1 and LNX2 isoforms led to loss of Cx36-containing gap junctions between cells, whereas these junctions persisted following transfection with isoforms of these proteins that lack ligase activity. Our results suggest that a LNX protein mediates ubiquitination of Cx36 at neuronal gap junctions, with consequent Cx36 internalization, and may thereby contribute to intracellular mechanisms that govern the recently identified modifiability of synaptic transmission at electrical synapses. PMID- 30295975 TI - Early (90-day) mortality after radical radiotherapy for head and neck squamous cell carcinoma: A population-based analysis. AB - BACKGROUND: A retrospective, population-based analysis of 90-day mortality in patients with squamous cell carcinoma of the head and neck treated with radiotherapy was performed to determine the early mortality rate and associated risk factors. METHODS: Data were abstracted for all consecutive patients with cancer of the head and neck treated from 1998 to 2014 at the BC Cancer Agency with curative intent radiotherapy (n = 5658). Logistic regression analysis was used to determine factors associated with early mortality. RESULTS: The median age at diagnosis was 63 years. The mortality rate at 90 days after starting radiotherapy (RT) was 3.6% (n = 203/5658). The cause of death was attributed to head and neck cancer for 81% of patients. Multivariate analysis demonstrated that increasing age, oral cavity subsite, and advanced T and N classification were associated with an increased risk of early mortality (p < .05). CONCLUSIONS: The risk of early mortality was 3.6%. Elderly patients with advanced T and N classification had the highest risk of early mortality.

PMID- 30295976 TI - Copper-Catalyzed Radical Cross-Coupling of Redox-Active Oxime Esters, Styrenes, and Boronic Acids. AB - A visible-light-driven, copper-catalyzed three-component radical cross-coupling of oxime esters, styrenes, and boronic acids has been developed. Key steps of this protocol involve catalytic generation of an iminyl radical from a redox active oxime ester and subsequent C-C bond cleavage to generate a cyanoalkyl radical. Upon its addition to styrene, the newly formed benzylic radical undergoes coupling with a boronic-acid-derived ArCuII complex to achieve 1,1 diarylmethane-containing alkylnitriles. PMID- 30295973 TI - Associations of maternal immune response with MeHg exposure at 28 weeks' gestation in the Seychelles Child Development Study. AB - PROBLEM: Maternal methylmercury (MeHg) exposure may be associated with immune response during pregnancy. METHOD OF STUDY: In the high fish-eating Seychelles Child Development Study Nutrition Cohort 2, we examined the association between maternal MeHg, polyunsaturated fatty acids (PUFA), and immune markers (Th1:Th2; TNF-alpha, IL-1beta, IFN-gamma, IL-2, IL-4, IL-5, IL-10, MCP-1, TARC, sFlt-1, VEGF-D, CRP and IL-6) at 28 weeks' gestation. Linear regression examined associations between MeHg exposure and immune markers with and without adjustment for PUFA. RESULTS: In all models, as MeHg concentrations increased, the Th1:Th2 ratio, total Th1 and individual Th1 (IL-1beta, IL-2, TNF-alpha) concentrations decreased. MeHg was not associated with total Th2 cytokines but was associated with a decrease in IL-4 and IL-10. MeHg was positively associated with TARC and VEGF-D and negatively associated with CRP. There was a significant interaction between MeHg and the n-6:n-3 ratio, with MeHg associated with a larger decrease in Th1:Th2 at higher n-6:n-3 PUFA ratios. The n-3 PUFA were associated with lower CRP, IL-4 and higher IFN-gamma. The n-6 PUFA were associated with higher IL 1beta, IL-2, TNF-alpha, IL-4, IL-10, CRP and IL-6. CONCLUSION: Maternal MeHg was associated with markers of immune function at 28 weeks' gestation. A significant interaction between MeHg and the n-6:n-3 ratio on the Th1:Th2 ratio suggests that the n-3 PUFA may mitigate any immunosuppressive associations of MeHg. The n-3 and n-6 PUFA were associated with suppressive and stimulatory immune responses, respectively. Overall, the associations were of small magnitude, and further research is required to determine the clinical significance.

AB - BACKGROUND AND PURPOSE: Gliosarcoma (GSC) is an intra-axial lesion which often abuts a dural margin and is composed of glial and mesenchymal elements. This lesion is considered a variant of isocitrate dehydrogenase (IDH)-wild type glioblastoma (GBM). The purpose of this study is to evaluate the imaging and molecular features of GSC in a large patient cohort. METHODS: Pathology-proved GSC cases were collected from our quaternary care center spanning the last 16 years and IDH status was documented. Older GSC cases without prior immunohistochemical testing underwent tissue block staining to obtain IDH status. When available, p53, phosphate and tensin (PTEN), MIB-1, EGFR amplification, and MGMT methylation were recorded and imaging findings tabulated. Logistic regression analyses were performed to determine correlation of molecular markers and imaging characteristics. RESULTS: A total of 25 cases were identified (21 de novo, 4 post-treatment). All lesions contacted a dural, pial, or ependymal surface and were negative for an IDH R132H mutation, including postradiation GSC. In total, 16 of 16 cases showed nonamplification of EGFR/CEP7, 2 of 16 demonstrated MGMT methylation, and multiple lesions demonstrated p53 and PTEN mutations. Imaging features included areas of nodular thickening in necrotic lesions which appeared to abut the site of dural contact. There was no significant correlation of molecular markers with imaging characteristics. CONCLUSION: GSC was IDH(-) in all cases, supporting the current understanding of this lesion being a wild-type GBM variant. Additional molecular markers demonstrated no significant correlation with imaging findings in this cohort. PMID- 30295980 TI - Assessing the methodological quality of the Canadian Psychiatric Association's anxiety and depression clinical practice guidelines. AB - RATIONALE, AIMS, AND OBJECTIVES: Clinical practice guidelines (CPGs) endeavour to incorporate the best available research evidence together with the clinically informed opinions of leading experts in order to guide clinical practice when dealing with a given condition. There has been increased interest in CPGs that are evidence based and that promote best practice, a central component of which is incorporating the best available research predicated on strong study designs. Despite this soaring interest, there remains heterogeneity in the methodological quality of many CPGs, which may have an effect on the quality of services that clinicians offer. In light of this, this study examined the quality of the methodology used to develop two CPGs of the Canadian Psychiatric Association (CPA). METHOD: The CPA's guidelines for the management of anxiety disorders (2006) and for the treatment of depressive disorders (2001) were assessed by trained raters using the Appraisal of Guidelines for Research and Evaluation II Instrument scale. RESULTS: The blind ratings of three trained raters demonstrated that the anxiety and depression CPGs had a number of strengths and important weaknesses. CONCLUSION: Implications for the development of future CPGs on anxiety and depression, including recommendations to improve guideline quality in psychiatry in particular, are discussed.

AB - The selective functionalization of chemically inert C-H bonds remains to be fully realized in achieving organic transformations that are redox-neutral, waste limiting, and atom-economical. The catalytic generation of chlorine atoms from chloride ions is one of the most challenging redox processes, where the requirement of harsh and oxidizing reaction conditions renders it seldom utilized in synthetic applications. We report the mild, controlled, and catalytic generation of chlorine atoms as a new opportunity for access to a wide variety of hydrogen atom transfer (HAT) reactions owing to the high stability of HCl. The discovery of the photoredox mediated generation of chlorine atoms with Ir-based polypyridyl complex, [Ir(dF(CF3 )ppy)2 (dtbbpy)]Cl, under blue LED irradiation is reported.

The reaction features excellent chemo- and regioselectivity, high functional-group tolerance, and very mild reaction conditions. PMID- 30295984 TI - Special Issue: Materials Research in Israel. PMID- 30295985 TI - Constructing Universal Ionic Sieves via Alignment of Two-Dimensional Covalent Organic Frameworks (COFs). AB - The shuttle effect of electrode materials always leads to capacity loss and poor cycle life of batteries. Two-dimensional (2D) covalent organic frameworks (COFs) with uniform and controllable nanopores provide a promising strategy for fabricating ionic sieves to inhibit the shuttle effect. However, the insoluble nature of COFs made it difficult to fabricate compact and ordered membranes of COFs. Herein, we report a novel method for facilely anisotropic ordering of 2D COFs via depositing COFs onto graphene. The resulted double-layer membranes acting as ionic sieves impressively inhibit the shuttle effect and exhibit versatility to both organic sodium-ion batteries and Li-S batteries, leading to high cyclability. PMID- 30295987 TI - MRI-Guided High-Intensity Focused Ultrasound as an Emerging Therapy for Stroke: A Review. AB - Stroke, either ischemic or hemorrhagic, accounts for significantly high morbidity and mortality rates around the globe effecting millions of lives annually. For the past few decades, ultrasound has been extensively investigated to promote clot lysis for the treatment of stroke, myocardial infarction, and acute peripheral arterial occlusions, with or without the use of tPA or contrast agents. In the age of modern minimal invasive techniques, magnetic resonance imaging-guided high-intensity focused ultrasound is a new emerging modality that seems to promise therapeutic utilities for both ischemic and hemorrhagic stroke. High-intensity focused ultrasound causes thermal heating as the tissue absorbs the mechanical energy transmitted by the ultrasonic waves leading to tissue denaturation and coagulation. Several in-vitro and in-vivo studies have demonstrated the viability of this technology for sonothrombolysis in both types of stroke and have warranted clinical trials. Apart from safety and efficacy, initiation of trials would further enable answers regarding its practical application in a clinical setup. Though this technology has been under study for treatment of various brain diseases for some decades now, relatively very few neurologists and even neurosurgeons seem to be acquainted with it. The aim of this review is to provide basic understanding of this powerful technology and discuss its clinical application and potential role as an emerging viable therapeutic option for the future management of stroke. PMID- 30295989 TI - Plasmacytoma variant translocation 1 (PVT1) regulates trophoblast viability, proliferation, and migration and is downregulated in spontaneous abortion. AB - PROBLEM: Human pregnancy is a complex biological process, and spontaneous abortion is the most common complication of pregnancy. LncRNAs have been identified that play key roles in a variety of human diseases. Recently, lncRNAPVT1 was reported to relate to the pathogenesis and progression of pregnancy. However, the role and underlying mechanism of PVT1 in trophoblast cell dysfunction in spontaneous abortion remain largely unknown. METHOD OF STUDY: The effects of PVT1, miR-424, and eIF5A on HTR8 cells and human villi tissues from spontaneous or induced abortions were investigated using CCK-8 assay, EdU assay, real-time polymerase chain reaction, Western blotting, cell transfection assays, cell migration assays, and luciferase reporter gene assays. RESULTS: Overexpression of PVT1 promoted HTR8 cell viability, proliferation, and migration. Suppression of PVT1 promoted miR-424 expression, and miR-424 could modulate the effects of PVT1 in HTR8 cells. MiR-424 exerted its function via regulation of eIF5A expression in HTR8 cells. PVT1 and eIF5A expression were decreased and miR-424 was increased in clinical samples from spontaneous abortion, compared to samples from elective induced abortion. CONCLUSION: PVT1 regulates trophoblast cell function via modulation of a PVT1/miR-424/eIF5A pathway.

AB - The sensitive imaging of amyloid-beta (Abeta) peptides is important for the timely detection of neurodegenerative diseases, such as Alzheimer's disease (AD). Although clinically the diagnosis of AD relies on the use of radiolabeled imaging reagents, herein we report the simple construction of a "flat ensemble" formed between a quinoline-malononitrile AIEgen (EDS) and thin-layer molybdenum disulfide (2D MoS2 ) for the sensitive detection of Abeta by means of fluorescence-based techniques. Self-assembly between EDS and 2D MoS2 in aqueous buffer solution produces the flat ensemble, and the subsequent interaction of the material ensemble with oligomeric and aggregated Abeta peptides leads to up to 19 fold enhanced fluorescence of EDS. The ensemble is also applicable for staining Abeta aggregates in vivo. PMID- 30295986 TI - Identification of Novel Gata3 Distal Enhancers Active in Mouse Embryonic Lens. AB - BACKGROUND: The tissue-specific transcriptional programs during normal development require tight control by distal cis-regulatory elements, such as enhancers, with specific DNA sequences recognized by transcription factors, coactivators, and chromatin remodeling enzymes. Gata3 is a sequence-specific DNA binding transcription factor that regulates formation of multiple tissues and organs, including inner ear, lens, mammary gland, T-cells, urogenital system, and thyroid gland. In the eye, Gata3 has a highly restricted expression domain in the posterior part of the lens vesicle; however, the underlying regulatory mechanisms are unknown. RESULTS: Here we describe the identification of a novel bipartite Gata3 lens-specific enhancer located ~18 kb upstream from its transcriptional start site. We also found that a 5-kb Gata3 promoter possesses low activity in the lens. The bipartite enhancer contains arrays of AP-1, Ets-, and Smad1/5 binding sites as well as binding sites for lens-associated DNA-binding factors. Transient transfection studies of the promoter with the bipartite enhancer showed enhanced activation by BMP4 and FGF2. CONCLUSIONS: These studies identify a novel distal enhancer of Gata3 with high activity in lens and indicate that BMP and FGF signaling can up-regulate expression of Gata3 in differentiating lens fiber cells through the identified Gata3 enhancer and promoter elements.

PMID- 30295988 TI - Influence of lack of posterior occlusal support on cognitive decline among 80 year-old Japanese people in a 3-year prospective study. AB - AIM: Previous studies have reported significant associations between tooth loss or periodontal status and cognitive function; however, animal experimental studies have shown that occlusion might be a more important factor in cognitive decline. The purpose of the present study was to investigate the influence of a lack of posterior occlusal support by residual teeth on the decline of cognitive function over a 3-year period among 80-year-old Japanese people. METHODS: Participants were community-dwelling older adults (n = 515, age 79-81 years). Cognitive function was measured using the Japanese version of the Montreal Cognitive Assessment. At baseline, participants were divided into two groups: those with and without posterior occlusal support. Participants whose Japanese version of the Montreal Cognitive Assessment score decreased by >=3 points over the 3-year period were defined as the declined group. Logistic regression was carried out for the decline in Japanese version of the Montreal Cognitive Assessment scores, including dental status and possible risk factors as independent variables. RESULTS: More participants without posterior occlusal support tended to be in the cognitive decline group (49.4%) than in the maintained group (38.5%; chi2 -test, P = 0.02). Logistic regression analysis showed that a lack of posterior occlusal support was a significant variable (odds ratio 1.55, P = 0.03) for cognitive decline, even after adjusting for other risk factors. However, the number of teeth or mean periodontal pocket depth was not significantly correlated with cognitive decline. CONCLUSIONS: The present findings suggest that a lack of posterior occlusal support predicted the incidence of cognitive decline, even after adjusting for possible risk factors in community-dwelling old-old people.

AB - Biogenic gold nanorod (AuNR)-Ag core-shell nanocomposites (NCs) are synthesized by using recombinant Escherichia coli to demonstrate in vivo synthesis of biogenic NCs for the first time. The chemically synthesized AuNRs are internalized into the E. coli, and Ag ions are reduced and grown on the surface of the AuNRs with the assistance of metal-binding proteins, producing biogenic core-shell AuNR-Ag NCs. The core-shell structure of the biogenic AuNR-Ag NC is confirmed by transmission electron microscopy and energy-dispersive X-ray analysis. The biogenic AuNR-Ag NCs exhibit good plasmonic effects. While the core shell morphology of the AuNR and Ag NCs is due to the similar lattice of Au and Ag, the shape of the biogenic NCs composed of gold nanoparticles and Fe is aciniform, and that of Fe3 O4 NPs and Au/Ag is a network structure, demonstrating the controllability of biogenic nanosynthesis using diverse metal combinations with different NC morphologies.

AB - OBJECTIVE: To noninvasively determine the relationship between the thickness of the buccal bone and attached gingiva of the maxillary premolars. MATERIAL AND METHODS: 128 maxillary premolars in 32 patients were assessed for measurement of buccal bone thickness and corresponding attached gingival thickness at 3 mm apical to cemento-enamel junction. Buccal bone thickness was measured on cone beam computed tomography scans and attached gingival thickness by ultrasound unit. Pearson's correlation coefficient was calculated to assess the correlation between buccal bone and attached gingival thickness at each tooth type. RESULTS: The mean buccal bone thickness at the maxillary premolars was 1.07 mm. The 1st premolars had a buccal bone thickness < 1 mm at 68% of all sites, and the 2nd premolars had a buccal bone thickness of 1.0-2.0 mm at 32% of all sites. The 1st premolars had a gingival thickness > 1.2 mm at 55% of all sites, and the 2nd premolars had a gingival thickness of 1.1-1.3 mm at 45% of all sites. The correlation between buccal bone and attached gingival thickness was moderately positive (r = 0.406; P < .001). CONCLUSIONS: The relationship between buccal bone thickness and gingival thickness is independent of each other in the maxillary right first premolar, whereas a moderate correlation with a dependent relation exists in the maxillary right second premolar, maxillary left first premolar, and maxillary left second premolar. CLINICAL SIGNIFICANCE: Soft tissue and hard tissue associated with volumetric changes in maxillary premolar region can be unfavorable for both aesthetic and implant placement. In fact this study highlighted the relationship between the thickness of attached gingiva and corresponding buccal bone in maxillary premolar region so to enable for proper planning of implant therapy following extraction.

AB - Deposition of amyloid-beta (Abeta) aggregates and formation of neurotoxic reactive oxygen species (ROS) are significant pathological signatures of Alzheimer's disease (AD). Resveratrol (Res) is an antioxidant with the potential to treat AD. However, the bioavailability and solubility of Res is very low and it cannot entirely inhibit Cu2+ -induced Abeta42 aggregation at low concentration. Herein, we combine the unique Abeta absorption property of selenium nanoparticles with the natural antioxidant agent Res to form Res@SeNPs. Our in vitro biological evaluation revealed that modification of Res with SeNPs provides a synergistic effect on Cu2+ -induced Abeta42 aggregation, ROS generation and, more importantly, protects PC12 cells from Abeta42-Cu2+ complexes induced cell death. It is believed that SeNPs can improve the application of Res in AD treatment as Res@SeNPs is more efficient than Res in reducing Abeta42 toxicity in long-term use. (c) 2018 Wiley Periodicals, Inc.

AB - BACKGROUND/AIMS: Mouthguard retention could potentially increase an athlete's motivation to wear the device, due to potential improvements in physical comfort. The aim of this study was to examine the retentive properties of selected customised mouthguard designs, during normal conditions (dry) and within the presence of artificial saliva (wet). Additionally, the correlation between thickness and retention was investigated. MATERIAL AND METHODS: Six different custom mouthguard designs (MG1-MG6) reported in previous studies, were pressure formed with 2 and 4 mm blanks accordingly. Thickness was measured 10 times at seven anatomical points and the mean (+/-SD) was recorded. A novel rig was fabricated to connect the mouthguards to a Hounsfield H10KS Tensometer, which was used to fully displace each device from the model at a constant rate of 50 mm/min. The test was repeated under both dry and wet conditions. RESULTS: Retention forces recorded at the anterior region demonstrated higher measurements under wet conditions than dry (P < 0.001). The total retention of the mouthguards was influenced by alterations in their design. Trend analysis indicated that 64% of MG retention could be explained by their thickness under dry conditions and 55% when wet. CONCLUSIONS: Design and thickness of mouthguards are key factors in retention. Mouthguard fabrication techniques should be considered in order to minimize dislodgment of the devices as well as potentially increasing the wearability of mouthguards during sport.

AB - Despite medical and surgical advancements for the treatment of cardiovascular disease, mortality and morbidity remain high. Therapeutic angiogenesis has been one approach to address the major clinical need for a more effective treatment to restoring blood flow in ischemic organs and tissues, but current progress in angiogenic drug delivery is inadequate at providing sufficient bioavailability without causing safety concerns. An injectable sulfonated reversible thermal gel composed of a polyurea conjugated with poly(N-isopropylacrylamide) and sulfonate groups has been developed for the delivery of angiogenic factors. The thermal gel allowed for the spatiotemporal control of vascular endothelial growth factor release with a decreased initial burst release and reduced release rate in vitro. A subcutaneous injection mouse model was used to evaluate efficacious vascularization and assess the inflammatory response due to a foreign body. Thermal gel injections showed substantial vascularization properties by inducing vessel formation, recruitment and differentiation of vascular endothelial cells, and vessel stabilization by perivascular cells, while infiltrating macrophages due to the thermal gel injections decreased over time. These results demonstrated effective localization and delivery of angiogenic factors for therapeutic angiogenesis. (c) 2018 Wiley Periodicals, Inc. J Biomed Mater Res Part A: 106A: 3053-3064, 2018. PMID- 30295998 TI - Brain-selective mild hypothermia promotes long-term white matter integrity after ischemic stroke in mice. AB - INTRODUCTION: The neuroprotective effects of hypothermia in acute ischemic stroke are well documented. However, the mechanisms involved in the effects remain to be clearly elucidated and the role of hypothermia on long-term white matter integrity after acute ischemic stroke has yet to be investigated. AIMS: To investigate the role of mild focal hypothermia on long-term white matter (WM) integrity after transient cerebral ischemia. RESULTS: Mild focal hypothermia treatment immediately after ischemic stroke significantly promotes WM integrity 28 days after the occlusion of the middle cerebral artery (MCAO) in mice. Higher integrity of white matter, lower activation of total microglia, less infarct volume, and better neurobehavioral function were detected in hypothermia-treated mice compared to normothermia-treated mice. Furthermore, we found that hypothermia could decrease detrimental M1 phenotype microglia and promote healthy M2 phenotype microglia. In vitro, results also indicated that hypothermia promoted oligodendrocytes differentiation and maturation after oxygen glucose deprivation. CONCLUSION: Hypothermia promotes long-term WM integrity and inhibits neuroinflammation in a mouse model of ischemic brain injury.

PMID- 30296000 TI - Long-term retention of avulsed maxillary permanent incisors replanted after prolonged non-physiological storage. AB - Ankylosis and external replacement resorption (ERR) are two typical biological responses to delayed replantation of avulsed teeth in cases where adequate root canal treatment is performed. The patient's growth stage affects the progression of root resorption and the long-term outcome of the affected teeth. This case report describes the long-term outcome of an 18.5-year-old patient following an accident in which both of his maxillary central incisors were avulsed and replanted after four hours of non-physiological storage. ERR and ankylosis of teeth 11 and 21 were detected clinically and radiographically during the second year of follow-up. Sixteen years after replantation, replacement resorption was progressing very slowly, enabling functional tooth retention with favorable esthetics. Young adults, with delayed replantation of avulsed teeth, may benefit from tooth retention with slow ERR. PMID- 30296002 TI - The extracellular protease AdamTS-B inhibits vein formation in the Drosophila wing. AB - Vein patterning in the Drosophila wing provides a powerful tool to study regulation of various signaling pathways. Here we show that the ADAMTS extracellular protease AdamTS-B (CG4096) is expressed in the embryonic wing imaginal disc precursor cells and the wing imaginal disc, and functions to inhibit wing vein formation. Knock-down of AdamTS-B displayed posterior crossveins (PCVs) with either extra branches or deltas, or wider PCVs, and a wandering distal tip of the L5 longitudinal vein. Conversely, over-expression of AdamTS-B resulted in a complete absence of the PCV, an incomplete anterior crossvein, and missing distal end of the L5 longitudinal vein. We conclude that AdamTS-B inhibits wing vein formation through negative regulation of signaling pathways, possibly BMP as well as Egfr, displaying the complexity of roles for this family of extracellular proteases. PMID- 30296001 TI - Towards patterned bioelectronics: facilitated immobilization of exoelectrogenic Escherichia coli with heterologous pili. AB - Biosensors detect signals using biological sensing components such as redox enzymes and biological cells. Although cellular versatility can be beneficial for different applications, limited stability and efficiency in signal transduction at electrode surfaces represent a challenge. Recent studies have shown that the Mtr electron conduit from Shewanella oneidensis MR-1 can be produced in Escherichia coli to generate an exoelectrogenic model system with well characterized genetic tools. However, means to specifically immobilize this organism at solid substrates as electroactive biofilms have not been tested previously. Here, we show that mannose-binding Fim pili can be produced in exoelectrogenic E. coli and can be used to selectively attach cells to a mannose coated material. Importantly, cells expressing fim genes retained current production by the heterologous Mtr electron conduit. Our results demonstrate the versatility of the exoelectrogenic E. coli system and motivate future work that aims to produce patterned biofilms for bioelectronic devices that can respond to various biochemical signals. PMID- 30296003 TI - Log margin-to-thickness ratio improves disease-specific survival prediction in oral cancer: A single cancer centre database. AB - OBJECTIVE: We examined whether dynamic margin criteria margin-to-thickness (MTR) ratio has superior predictive value compared with the resection margin or tumour thickness alone in the survival outcome in oral squamous cell carcinoma (OSCC). DESIGN: This is a retrospective cohort study. SETTING: Oral squamous cell carcinoma patients treated in Kaohsiung Veterans General Hospital Cancer Center between January 2006 and December 2013. PARTICIPANTS: A cohort of 302 patients with OSCC who had undergone surgical management. MAIN OUTCOMES MEASURES: Log MTR was calculated for each patient, and survival data were analysed using a multivariable Cox regression model. Discriminative analysis was performed using chi-square, Akaike information criterion (AIC) and Harrell's C tests. RESULTS: After assessing for discriminative ability, the linear trend of log MTR surpassed those of resection margin and tumour thickness in chi-square, AIC and Harrell's C tests for the advanced pathologic T (pT) category. A multivariate Cox proportional hazard regression model revealed that log MTR <33% was associated with less favourable 5-year disease-specific survival (DSS) (P = 0.006) in the entire oral cancer study cohort. Other significant factors included perineural invasion (P = 0.021), pT category, (P = 0.005), pathologic N category (P < 0.001) and differentiation category (P = 0.022). CONCLUSIONS: Log MTR < 33% may be a predictor of less favourable outcome in the DSS of OSCC. Log MTR outperformed both resection margin and tumour thickness alone in terms of discriminative analysis. Our study could help in presurgical planning for high-risk patients and in aiding the decision-making process for adjuvant treatment. PMID- 30296004 TI - Emergency Preparedness Training for Hospital Nursing Staff, New York City, 2012 2016. AB - PURPOSE: Many nurses are trained inadequately in emergency preparedness (EP), preventing them from effectively executing response roles during disasters, such as chemical, biological, radiological, nuclear, and explosive (CBRNE) events. Nurses also indicate lacking confidence in their abilities to perform EP activities. The purpose of this article is to describe the phased development of, and delivery strategies for, a CBRNE curriculum to enhance EP among nursing professionals. The New York City (NYC) Department of Health and Mental Hygiene (DOHMH) and the National Center for Disaster Preparedness at Columbia University's Earth Institute led the initiative. METHODS: Curriculum development included four phases. In Phases I and II, nursing staff at 20 participating NYC hospitals conducted 7,177 surveys and participated in 20 focus groups to identify training gaps in EP. In Phase III, investigators developed and later refined the CBRNE curriculum based on gaps identified. In Phase IV, 22 nurse educators (representing 7 of the original 20 participating hospitals) completed train-the trainer sessions. Of these nurse educators, three were evaluated on their ability to train other nurses using the curriculum, which investigators finalized. FINDINGS: The CBRNE curriculum included six modules, a just-in-time training, and an online annual refresher course that addressed EP gaps identified in surveys and focus groups. Among the 11 nurses who were trained by three nurse educators during a pilot training, participant knowledge of CBRNE events and response roles increased from an average of 54% (range 45%-75%) on the pre-test to 89% (range 80%-90%) on the posttest. CONCLUSIONS: By participating in nursing CBRNE training, nurses increased their knowledge of and preparedness to respond to disasters. The train-the-trainer curriculum is easily adaptable to meet the needs of other healthcare settings. CLINICAL RELEVANCE: The CBRNE curriculum can be used to train nurses to better prepare for and more effectively respond to disasters. PMID- 30296005 TI - Choosing a dialyzer: What clinicians need to know. AB - The objectives of hemodialysis have moved from the diffusive clearance of small molecular weight uremic toxins and achieving dialyzer urea adequacy targets to emphasis on improving clinical outcomes in end stage renal failure patients by increasing larger sized uremic toxin clearance. Clinical emphasis in the last few decades has focused on increasing middle molecule weight toxin clearance by hemodiafiltration. Although long-term data is still lacking, short-term outcomes appear promising. Advancements in nanotechnology have now introduction a new generation of medium cut-off membrane dialyzers which allow diffusive clearance of similar middle molecular weight uremia toxin clearance as hemodiafiltration, without increased albumin losses. As these dialyzers have only recently been introduced into clinical practice, no long-term outcomes are available to determine the relative benefits or advantages of this approach. As dialyzers are now designed to maximize diffusive or convective clearance, or provide a combination, then clinicians can now choose dialyzers tailored to the individual patient needs depending on clinical circumstances. We review the key important features in choosing a dialyzer for patients with end stage renal failure and acute kidney injury. PMID- 30296006 TI - SIRT3 activator honokiol ameliorates surgery/anesthesia-induced cognitive decline in mice through anti-oxidative stress and anti-inflammatory in hippocampus. AB - AIMS: Increasing evidence indicates that neuroinflammatory and oxidative stress play two pivotal roles in cognitive impairment after surgery. Honokiol (HNK), as an activator of Sirtuin3 (SIRT3), has potential multiple biological functions. The aim of these experiments is to evaluate the effects of HNK on surgery/anesthesia-induced cognitive decline in mice. METHODS: Adult C57BL/6 mice received a laparotomy under sevoflurane anesthesia and HNK or SIRT3 inhibitor (3 TYP) treatment. Cognitive function and locomotor activity of mice were evaluated using fear conditioning test and open field test on postoperative 1 and 3 days. Neuronal apoptosis in CA1 and CA3 area of hippocampus was examined using TUNEL assay. And Western blot was applied to measure the expression of pro-inflammatory cytokines and SIRT3/SOD2 signaling-associated proteins in hippocampus. Meanwhile, SIRT3 positive cells were calculated by immunohistochemistry. The mitochondrial membrane potential, malondialdehyde (MDA), and mitochondrial radical oxygen species (mtROS) were detected using standard methods. RESULTS: Honokiol attenuated surgery-induced memory loss and neuronal apoptosis, decreased neuroinflammatory response, and ameliorated oxidative damage in hippocampus. Notably, surgery/anesthesia induced an obviously decrease in hippocampal SIRT3 expression, whereas the HNK increased SIRT3 expression and thus decreased the acetylation of superoxide dismutase 2 (SOD2). However, 3-TYP treatment inhibited the HNK's rescuing effects. CONCLUSIONS: These results suggested that activation of SIRT3 by honokiol may attenuate surgery/anesthesia-induced cognitive impairment in mice through regulation of oxidative stress and neuroinflammatory in hippocampus. PMID- 30296007 TI - Technique for tailoring complex demarcation in lung segmentectomy. AB - Segmentectomy is a widely adopted surgical procedure, however, experiences of tailoring the intersegmental border have rarely been reported. This paper investigates the strategy and results of tailoring complex demarcation during lung segmentectomy surgery. Because intersegmental demarcation can be divided into plane or curved types according to the location and stereo shape of a segment, a one-size-fits-all method for tailoring the intersegmental demarcation is obviously unreasonable. For tailoring a complex segmentectomy with two or more curved borders, tips including good exposure of the intersegmental demarcation, sharp-blunt combined dissection skill, "work-plane" extension, and "gate" opening techniques all contribute to an accurate segmentectomy. This technique, based on anatomical characteristics, can provide a cutting surface with a greater physiological shape and less curling of the edge, and should be recommended as a general standard method for tailoring complex demarcation.

AB - Gut microbiome contributes to host health by maintaining homeostasis, increasing digestive efficiency, and facilitating the development of immune system. Wild greylag geese (Anser anser) and ruddy shelducks (Tadorna ferruginea), migrating along the central Asian flyway, appear to be one of the most popular species in the rare birds rearing industries of China. However, the structure and function of the gut microbial communities associated with these two bird species remain poorly understood. Here, for the first time, we compared gut metagenomes from greylag geese to ruddy shelducks and investigated the similarities and differences between these two bird species in detail. Taxonomic classifications revealed the top three bacterial phyla, Firmicutes, Proteobacteria, and Fusobacteria, in both greylag geese and ruddy shelducks. Furthermore, between the two species, 12 bacterial genera were found to be more abundant in ruddy shelducks and 41 genera were significantly higher in greylag geese. A total of 613 genera (approximately 70%) were found to be present in both groups. Metabolic categories related to carbohydrate metabolism, metabolism of cofactors and vitamins, lipid metabolism, amino acid metabolism, and glycan biosynthesis and metabolism were significantly more abundant in ruddy shelducks, while greylag geese were enriched in nucleotide metabolism and energy metabolism. The herbivorous greylag geese gut microbiota harbored more carbohydrate-active enzymes than omnivorous ruddy shelducks. In our study, a range of antibiotic resistance categories were also identified in the gut microbiota of greylag geese and ruddy shelducks. In addition to providing a better understanding of the composition and function of wild birds gut microbiome, this comparative study provides reference values of the artificial domestication of these birds. PMID- 30296009 TI - The relationships between urinary glycosaminoglycan levels and phenotypes of mucopolysaccharidoses. AB - BACKGROUND: The aim of this study was to use the liquid chromatography/tandem mass spectrometry (LC-MS/MS) method to quantitate levels of three urinary glycosaminoglycans (GAGs; dermatan sulfate [DS], heparan sulfate [HS], and keratan sulfate [KS]) to help make a correct diagnosis of mucopolysaccharidosis (MPS). METHODS: We analyzed the relationships between phenotypes and levels of urinary GAGs of 79 patients with different types of MPS. RESULTS: The patients with mental retardation (n = 21) had significantly higher levels of HS than those without mental retardation (n = 58; 328.8 vs. 3.2 MUg/ml, p < 0.001). The DS levels in the patients with hernia, hepatosplenomegaly, claw hands, coarse face, valvular heart disease, and joint stiffness were higher than those without. Twenty patients received enzyme replacement therapy (ERT) for 1-12.3 years. After ERT, the KS level decreased by 90% in the patients with MPS IVA compared to a 31% decrease in the change of dimethylmethylene blue (DMB) ratio. The DS level decreased by 79% after ERT in the patients with MPS VI compared to a 66% decrease in the change of DMB ratio. CONCLUSIONS: The measurement of GAG fractionation biomarkers using the LC-MS/MS method is a more sensitive and reliable tool than the DMB ratio for MPS high-risk screening, diagnosis, subclass identification, and monitoring the efficacy of ERT. PMID- 30296010 TI - Long-term follow-up of ICSI-conceived offspring compared with spontaneously conceived offspring: a systematic review of health outcomes beyond the neonatal period. AB - BACKGROUND: A significant increase in the use of intracytoplasmic sperm injection (ICSI) since its introduction in 1992 has been observed worldwide, including beyond its original intended use for severe male factor infertility. Concerns regarding ICSI include the effects of poor quality spermatozoa on offspring health and future fertility, and of the technique itself. The health and development of ICSI-conceived children beyond early infancy have not been comprehensively assessed. OBJECTIVE: A systematic review of health outcomes of ICSI-conceived offspring beyond the neonatal period compared to spontaneously conceived (SC) offspring. DESIGN: PubMed, OVID Medline/Embase, InformIT, Web of Science, and ProQuest databases were searched for studies reporting on health outcomes in ICSI-conceived offspring beyond 28 days after birth. MAIN OUTCOMES MEASURE(S): Physical and psychosocial health. RESULTS: The search strategy yielded 2826 articles. Of these, 2580 were not relevant or did not meet inclusion criteria and 138 were duplicates. One hundred and eight full-text papers were evaluated further, and 48 satisfied the inclusion criteria. Most studies reported on neurodevelopment during early infancy and childhood with reassuring results. Growth, vision, and hearing of ICSI and SC offspring also appear comparable, although important differences in general physical health, and particularly metabolic and reproductive health have been described, including recently poorer semen quality among ICSI-conceived young adult men compared to SC peers. CONCLUSION: Whilst neurodevelopment, growth, vision, and hearing appear similar between ICSI and SC children, evidence suggests differences in general physical health, and metabolic and reproductive endpoints. The clinical significance of many findings, however, remains unclear, and further prospective, large, and good quality studies with a focus on all these health outcomes in ICSI-conceived young adults are required. PMID- 30296011 TI - Highlights of eosinophilic chronic rhinosinusitis with nasal polyps in definition, prognosis, and advancement. AB - BACKGROUND: Tissue eosinophils are characteristic of inflammation in most but not all patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and may be useful for defining subgroups and making treatment choices. However, no consistent diagnostic criteria for CRSwNP with eosinophilic inflammation have been established. METHODS: Related literature review was performed and current developments in the diagnosis of eosinophilic CRSwNP were summarized. Details in histopathology, definition of tissue eosinophilia, eosinophil as an indicator of disease recurrence, eosinophilic shift, and related biomarkers in CRSwNP are included in this review article. RESULTS: Mucosal eosinophilia exhibits significant geographic and ethnic differences and may increase over time. Tissue eosinophilia can be defined using a cutoff value based on reference values from healthy mucosa, but typical disease-specific values should also be employed to increase sensitivity and specificity for clinical use. Recent developments highlight the diagnostic criteria for eosinophilic CRSwNP based on cluster analysis, which were also associated with clinical outcomes. Additionally, some promising eosinophil-relevant biomarkers, such as eosinophilic cation protein and interleukin 5 (IL-5), may be clinically applied as diagnostic or predictive tools for CRSwNP in the future. CONCLUSION: Sinonasal tissue eosinophilia is present in a majority of CRSwNP patients but is currently more common in the West than in the East. Cutoff values of eosinophils as the diagnostic criteria of eosinophilic CRSwNP are subject to change with geographic and ethnic differences over time. It will be important to identify validated eosinophil-related biomarkers in different continents/countries for future research and for the introduction of precision medicine. PMID- 30296012 TI - USP14 as a novel prognostic marker promotes cisplatin resistance via Akt/ERK signaling pathways in gastric cancer. AB - Gastric cancer (GC) ranks the third leading cause of global cancer mortality. Despite recent progress in surgery combined with chemotherapy, the outcomes of GC patients have barely improved. Therefore, better understanding of the molecular mechanisms involved in chemoresistance of GC may help develop novel strategies to treat this deadly disease. Previous evidence has shown aberrant expressions of USP14 in multiple malignancies, suggesting an important role of USP14 in tumorigenesis. However, its role in modulating chemoresistance in GC still remains elusive. In this study, we observed that USP14 levels were significantly increased in GC tissues compared to the paired normal tissues. Multivariate analysis demonstrated that USP14 level was an independent prognostic factor for DFS in GC patients. Silencing of USP14 promoted proteasomal degradation of p-ERK (T202/Y204) and p-Akt (T308/S473), thus inactivating Akt and ERK signaling pathways. Interestingly, silencing of USP14 alone was not sufficient to cause overt effects on cell growth, proliferation, and apoptosis, while resulting in significant apoptosis in the presence of cisplatin in GC cells. Thus, knockdown of USP14 sensitized GC cells to cisplatin by triggering cisplatin-induced apoptosis via impeding Akt and ERK signaling pathways. These results revealed a novel role of USP14 in modulating chemosensitivity of GC cells, suggesting USP14 may serve as not only a prognostic marker, but also a potential therapeutic target for GC patients. PMID- 30296013 TI - Validation of CPS+EG, Neo-Bioscore, and modified Neo-Bioscore staging systems after preoperative systemic therapy of breast cancer: Protocol of a retrospective multicenter cohort study in China. AB - Prognostic assessment after preoperative systemic therapy (PST) is critical to develop a therapeutic strategy for breast cancer management. Currently, a clinical-pathologic staging system that incorporates ER status and nuclear grading (CPS + EG), and the Neo-Bioscore system that includes HER2 status into CPS + EG, are used to predict outcomes in patients with breast cancer after PST. While HER2-positive is recognized as a favorable factor in the Neo-Bioscore system based on results in patients administered one year of trastuzumab as anti HER2 therapy, most HER2-positive cases have difficulty accessing anti-HER2 treatment in China. Therefore, it is crucial that a modified Neo-Bioscore staging system is developed that incorporates an additional factor of poor prognosis, HER2-positive status without trastuzumab treatment, to determine accurate prognosis. We propose a retrospective multicenter cohort study in China to validate CPS + EG, Neo-Bioscore, and the modified Neo-Bioscore system and determine the accuracy of prediction. Primary breast cancer patients without metastasis treated with PST and surgery in academic institutions or hospitals of provincial level in China will be included. Disease-free, disease specific, and overall survival will be calculated using the Kaplan-Meier Method, stratified by CPS + EG, Neo-Bioscore, and the modified Neo-Bioscore staging system. Areas under the curve of each staging system will be calculated. Multivariate analysis using Wald testing and maximum likelihood estimates in a Cox proportional hazards model will be conducted. PMID- 30296014 TI - Infection by Histoplasma capsulatum, Cryptococcus spp. and Paracoccidioides brasiliensis in bats collected in urban areas. AB - Epidemiological studies on endemic mycosis can be improved using molecular biology techniques to elucidate the role of bats as reservoirs and vectors of pathogenic fungi for infection of other animals and humans. The objective of this study was to explore the presence of Histoplasma capsulatum, Cryptococcus spp. and Paracoccidioides brasiliensis in insectivorous, frugivorous and nectarivorous bats collected in urban areas. We analysed 172 bats collected by the Epidemiological Surveillance Agency in 12 municipalities of the Midwest region of the state of Sao Paulo, Brazil. Spleen, liver, intestine and lung samples were subjected to microbiological culture and nested PCR analyses. Prevalence of H. capsulatum infection was 8.1% (14/172), with one bat found to be positive by fungal culturing, 12 positive by nested PCR and one positive by both methods. Two insectivorous bats were found positive by nested PCR for Cryptococcus spp., one in the spleen and the other in the spleen and lung. Two insectivorous bats showed natural infection by P. brasiliensis, in the spleen of one bat and the spleen and liver of the other. Our results reinforce the importance of bats as fungal dispersers in urban environments and the importance of constant epidemiologic surveillance because these synanthropic animals are in close contact with humans and animals. PMID- 30296015 TI - In situ and Operando Tracking of Microstructure and Volume Evolution of Silicon Electrodes by using Synchrotron X-ray Imaging. AB - The internal microstructure of a silicon electrode in a lithium ion battery was visualized by operando synchrotron X-ray radioscopy during battery cycling. The silicon particles were found to change their sizes upon lithiation and delithiation and the changes could be quantified. It was found that volume change of a particle is related to its initial size and is also largely determined by the changing surrounding electron-conductive network and internal interface chemical environment (e.g., electrolyte migration, solid-electrolyte interphase propagation) within fractured particles. Moreover, an expansion prolongation phenomenon was discovered whereby some particles continue expanding even after switching the battery current direction and shrinkage would be expected, which is explained by assuming different expansion characteristics of particle cores and outer regions. The study provides new basic insights into processes inside Si particles during lithiation and delithiation and also demonstrates the unique possibilities of operando synchrotron X-ray imaging for studying degradation mechanisms in battery materials. PMID- 30296016 TI - Toxins targeting transfer RNAs: Translation inhibition by bacterial toxin antitoxin systems. AB - Prokaryotic toxin-antitoxin (TA) systems are composed of a protein toxin and its cognate antitoxin. These systems are abundant in bacteria and archaea and play an important role in growth regulation. During favorable growth conditions, the antitoxin neutralizes the toxin's activity. However, during conditions of stress or starvation, the antitoxin is inactivated, freeing the toxin to inhibit growth and resulting in dormancy. One mechanism of growth inhibition used by several TA systems results from targeting transfer RNAs (tRNAs), either through preventing aminoacylation, acetylating the primary amino group, or endonucleolytic cleavage. All of these mechanisms inhibit translation and result in growth arrest. Many of these toxins only act on a specific tRNA or a specific subset of tRNAs; however, more work is necessary to understand the specificity determinants of these toxins. For the toxins whose specificity has been characterized, both sequence and structural components of the tRNA appear important for recognition by the toxin. Questions also remain regarding the mechanisms used by dormant bacteria to resume growth after toxin induction. Rescue of stalled ribosomes by transfer messenger RNAs, removal of acetylated amino groups from tRNAs, or ligation of cleaved RNA fragments have all been implicated as mechanisms for reversing toxin induced dormancy. However, the mechanisms of resuming growth after induction of the majority of tRNA targeting toxins are not yet understood.

PMID- 30296017 TI - Sustained and Bioresponsive Two-Stage Delivery of Therapeutic miRNA via Polyplex Micelle-Loaded Injectable Hydrogels for Inhibition of Intervertebral Disc Fibrosis. AB - Intervertebral disc degeneration (IDD) is frequently caused by gradual pathological changes inside intervertebral discs (IVDs) and progressive fibrosis. MicroRNA-29 (miR-29) family possesses potent fibrosis suppression capability, but their application for treatment of chronic IDD is limited due to lack of suitable local delivery systems. In this report, given various overexpressed matrix metalloproteinases (MMPs) during IDD, injectable MMP-degradable hydrogels encapsulating MMP-responsive polyplex micelles are developed for sustained and bioresponsive delivery of miR-29a into nucleus pulposus cells via a two-stage process. Cationic block copolymers are designed to complex miR-29a, and subsequently mixed with the poly(ethylene glycol) (PEG) gelation precursors and MMP-cleavable peptide cross-linkers for in situ formation of polyplex micelle encapsulated hydrogels in the diseased IVDs. In the presence of MMPs, the polyplex micelles are first released by MMP cleavage of the hydrogels, and subsequently, MMPs-responsive detachment of PEG shells from polyplex micelles contributes to efficient cellular uptake and endosomal escape. MiR-29a is demonstrated to effectively silence the expression of MMP-2, inhibit the fibrosis process, and reverse IDD in animal models through blocking the beta-catenin translocation pathway from the cytoplasm to the nucleus. This two-stage bioresponsive local miRNA delivery system represents a novel and promising strategy for the treatment of chronic IDD. PMID- 30296018 TI - Inadequate Accessibility: Why Uber Should Be a Public Accommodation Under the Americans With Disabilities Act. AB - This Comment will focus on Uber and its obligations under the Americans with Disabilities Act (ADA). While it may seem logical that Uber should adhere to the same ADA regulations as taxis, the relevant ADA provision only applies to private entities that are primarily engaged in the business of transporting people. To avoid these regulations, Uber asserts that it is primarily a technology company, rather than primarily a transportation company. However, the more expansive approach, consistent with the ADA's purpose of eliminating discrimination against persons with disabilities, is to classify Uber's services as public accommodations. While the ADA's public accommodation provision governs physical spaces such as restaurants, shopping centers, and offices, some jurisdictions have recently decided that web-based entities and services are public accommodations. Thus, even if a court were to accept Uber's claim that it is primarily a technology company rather than a transportation company, Uber would still be required to adhere to the ADA's public accommodation provision. This Comment presents and analyzes three rationales for defining Uber as a public accommodation under the ADA: (1) web-based activities are distinct public accommodations, (2) the physical vehicles that Uber operates are places of public accommodation, and (3) Uber is a "travel service" or "other service establishment" as defined in the ADA.

The vaccine against it is effective but requires evaluation of the immune response with the dosage of anti-HBs. Objective: Objectives: to determine the immunological response to the vaccine against hepatitis B in physicians, nurses and medical students of the National Hospital, Paraguay. Methods: an observational, analytical and cross-sectional study was conducted in a sample of 120 health workers during 2017. The level of anti-HBs was determined with quantitative immunoassay and demographic and clinical variables were recorded, with prior informed consent. Results: the sample was integrated with 79 women and 41 men. The mean age was 28+/-7 years. Physicians (62.5%), nurses (20%) and medical students (17.5%) were included. The mean BMI was 24.7 +/- 3.8 kg/m2. Adequate serum levels of anti-HBs (> 100 IU / mL) were detected in 64% of the health personnel. Obesity was a factor associated with poor response to the vaccine (p 0.02). Sex, age, the time elapsed since the last dose and smoking were factors not significantly associated with the lack of response to the vaccine. Conclusion: inadequate response to HB vaccine was found in 36%. Obesity was significantly associated with poor immunological response.

Objective: To determine epidemiological, microbiological and clinical features of community (CA-BI) and nosocomial bloodstream infections (N-BI). Methods: Bacteremia and fungemia events were retrospectively analyzed in two third-level hospitals between April 2009 and August 2013. Results: We identified 1150 events of bloodstream infections, 53.2% were CA-BI. Gram negative microorganisms were isolated in 61%. The most frequent pathogens were Escherichia coli in CA-BI and Klebsiella pneumoniae in N-BI. Staphylococcus aureus was the most frequent gram positive organism. The main comorbidities were renal disease (39%) and malignancy (38%). There were 26.8% of primary bloodstream infections, and the main infection foci included respiratory (17.04%) and urinary tract (16.86%). A high percentage of gram-negative bacteria of CA-BI and N-BI were resistance to ampicillin sulbactam (40.2% and 57.5%), cephalothin (36.7% and 46.8%), trimethoprim-sulfamethoxazole 32.8% vs 35.5%) and ciprofloxacin (24.6% and 35.3%). Methicillin-resistant Staphylococcus aureus were more frequently into ITS-IH (31.4% vs 11.8%, p = 0.007). Conclusions: Clinical and epidemiological characteristics of CA-BI and N-BI were similar to those reported by other Latin American studies. We observed some differences in antimicrobial resistance profiles. We emphasize the importance of local epidemiological surveillance to choose appropriate empirical treatments.

The determination of them by direct method is difficult in hospitalized patients. The objective was to analyze the correlation between weight and mid arm circumference (MAC), and between height and knee height (KH) of children and teenagers so it can be used to asses growth and nutritional status in hospitalized children. Population and methods: An observational, descriptive and cross-sectional study was carried out. We included children and teenagers of both gender of 2 and 19 years old. To establish the correlation, the correlation coefficient r and determination R2 were calculated with a significance of p <0.05, plotting the correlation. The MedCalc V12.5.0.0 software was used to analyze the data. Results: Data from 861 subjects were collected. 484 females (56.2% CI95% 52.8-59.5), and 377 males (43.8% CI 95% 40.4 47.2) aged between 2 and 19 years. A correlation was obtained between the KH and the height of r = 0.98 for both sexes, (R2 = 0.96 females and R2 = 0.97 in males), p <0.001. The MAC showed a correlation with the weight of r = 0.92 (R2 = 0.76) in males and r = 0.87 (R2 = 0.85) in females, both with p <0.001. Conclusions: Body segments KH and MAC have a high correlation with height and weight, respectively. That is why we propose to use them for the assessment of growth and nutritional status in hospitalized children with functional limitations.

The global prevalence was of 2% with a 13,3% in women under 25 years old (p< 0,001). A similar pattern was observed with respect to the educational level, with a higher prevalence on those who only had primary education, 18,2% (p<0.001); in women who presented a low gynecological sign or symptom 6,8% (p< 0,001) and in those patients whose sexual initiation was before 18 years old, 3,3% (p< 0,030). Conclusion: It is advisable to implement C. trachomatis screening as part of the pre natal screening in all pregnant women under 25 years old. Argentinian health care system should take this problem into account in order to achieve a rational control over the infections caused by this bacterium. PMID- 30296026 TI - Positive correlation between proteasome activity and polyphenols in the telencephalon of adult female mice. AB - INTRODUCTION: Proteasome regulates proteostasis, and can be compromised in neurodegenerative diseases. Thus, our aim was to correlate the activity of proteasome to the level of polyphenols in telencephalon during murine adulthood. METHODS: Proteasome activity, polyphenols and other variables (glucose and hydroperoxides) were analysed in Balb/c female telencephala (n = 20, age = 4-12 months), using multivariate methods. RESULTS: The following values were found: proteasome activity = 3.1 +/- 0.6 FI/ug of tissue proteins, glucose = 0.1 +/- 0.0 ug/ug, hydroperoxides = 363.4 +/- 96.6 OD/ug, and polyphenols = 0.1 +/- 0.0 ng/ug. Polyphenols reduced during aging showed a direct correlation with proteasome (Pearson's coefficient = 0.43, p = 0.0590, and a multivariate linear regressive coefficient = 17.85, p = 0.0216), with glucose and hydroperoxides being not involved (p>0.1). This correlation was confirmed by partial least square regression (beta = 0.67). CONCLUSION: Proteasome activity can be affected during ageing, and promoted by telencephalic polyphenol levels. Thus, these diet compounds might exert benefits in adult brain.

AB - Recent developments in gene-editing technology have enabled scientists to manipulate the human genome in unprecedented ways. One technology in particular, Clustered Regularly Interspaced Short Pallindromic Repeat (CRISPR), has made gene editing more precise and cost-effective than ever before. Indeed, scientists have already shown that CRISPR can eliminate genes linked to life-threatening diseases from an individual's genetic makeup and, when used on human embryos, CRISPR has the potential to permanently eliminate hereditary diseases from the human genome in its entirety. These developments have brought great hope to individuals and their families, who suffer from genetically linked diseases. But there is a dark side: in the wrong hands, CRISPR could negatively impact the course of human evolution or be used to create biological weaponry. Despite these possible consequences, CRISPR remains largely unregulated due to the United States's outdated regulatory scheme for biotechnology. Moreover, human embryo research, which is likely critical to maximizing the therapeutic applications of CRISPR, is not easily undertaken by scientists due to a number of federal and state restrictions aimed at preventing such research. This Note examines the possible benefits and consequences of CRISPR and discusses the current regulations in both the fields of biotechnology and human embryo research that hamper the government's ability to effectively regulate this technology. Ultimately, this Note proposes a new regulatory scheme for biotechnology that focuses on the processes used to create products using CRISPR, rather than the products themselves, with a focus on enabling ethical research using human embryos to maximize the potential benefits of CRISPR.

AB - Experimental data indicate that postconditioning at a distance is an effective method for cardiac protection against reperfusion injury. Remote postconditioning prevents reperfusion necrosis and apoptosis of cardiomyocytes, decreases a probability of postinfarction remodeling of the heart. Cardioprotective effect of remote postconditioning depends on the release of tissue factor(s) increasing cardiac tolerance to long-term ischemia-reperfusion after transient ischemia. Clinical investigations show that postconditioning at a distance is an effective method for the prevention of reperfusion injury of the heart during coronary artery bypass surgery.

AB - Introduction: Inflammation is probably the main process that links cardiovascular risk factors with damage to blood vessels and neurons. Elucidation of mechanisms of this relationship is an important issue. Materials and methods: 70 acute stroke patients were studied to assess their neuropsychological (MMSE, MoCA, FAB, Clock Drawing Test, Shulte Tables and Verbal Fluency) and functional status (mRS, Rivermead Mobility Index). The serum and liquor IL-1beta, IL-6, TNFa and IL-10 levels were analyzed. Control group included subjects without cerebrovascular diseases. Results: Stroke patients had higher IL-10 serum concentration than controls. No difference was found for other cytokines. There was correlation between serum and liquor cytokines levels. We found positive correlation between IL-1beta, IL-6 and IL-10 levels. High IL-1beta concentration was associated with vascular risk factors, cardio embolic stroke, enhanced severity of cerebral stroke, low processing speed, impaired executive and visual-spatial functions and higher grade of mRS on discharge. The same pattern was revealed for IL-6 and IL 10. IL-6 level was related to mRS without relation to NIHSS on admission. High TNFa concentration was linked with vascular risk factors, low MMSE score and processing speed. Discussion: Despite the antagonistic effects of IL-1beta, IL-6 and IL-10 on inflammation, associations of these cytokines with anamnestic, clinical, neuropsychological and functional characteristics were similar in acute ischemic stroke. Probably, this fact indicates that during the acute ischemic brain damage process the immune response develops at the same time in pro- and anti-inflammatory directions. Its magnitude correlates with the damage severity and is associated with the effects of vascular risk factors before stroke.

AB - Objective: To study characteristics of antibacterial therapy (ABT) at different stages of treatment of patients with infective endocarditis (IE) in clinical practice. Materials and methods: In retrospective (2001 to 2008) and prospective (2008 to 2014) studies lasting 14-years, 302 hospitalized patients with confirmed native valve IE were given antibiotic therapy at outpatient and inpatient stages of treatment. The choice of antibacterial drugs, duration and side effects of prolonged use of antibiotics (AB) were analyzed in comparison with the results of hospital treatment of patients with IE. Results: It was shown that outpatients with IE due to fever without a specific diagnosis, were frequently prescribed short courses of antibiotics with the prevalence of ceftriaxone monotherapy and its combination with aminoglycosides as the starting treatment under hospital conditions. The cases of incompliance with the recommended duration of antimicrobial therapy were documented. The most common side effects of AB included diarrheal disorders, but the most serious problem was nephrotoxicity resulting in total or partial withdrawal of ABT. Conclusions: The potential of antibiotic treatment of IE is employed but incompletely, the main obstacles to the implementation of adequate antibiotic therapy of IE being the low rate of early diagnosis of the disease including etiological one and the unacceptable level of long-term safety of ABT for the patients.

AB - The article reports results of clinical studies aimed to elucidate the influence of medicines on the size and density of atherosclerotic plaques in the walls of coronary and cerebral arteries. The phenomenon of regression of atherosclerotic lesions in the survivors of Leningrad siege during a long period of starvation is analyzed. The influence of inhibitors of angiotensin-converting enzyme on apoptosis of smooth muscle and foam cells of atherosclerotic plaques in the sanological mechanisms of atherosclerosis is discussed. The concept of natural regression of atherosclerosis is formulated and the necessity of development of the methods for is pharmacological activation are formulated. PMID- 30296042 TI - [CHARACTERISTIC OF APOPTOSIS OF CORONARY ARTERY CELLS WITH ATHEROSCLEROTIC LESIONS]. AB - Aim: To study apoptosis of endothelial cells (EC), macrophages (MF) and smooth muscle cells (SMC) in the early atherosclerotic process (prior to plaque formation), elucidate mechanisms of its realization and evaluate effect on progression of atherosclerosis. Materials and methods: Histopathological studies were performed on coronary arteries affected by atherosclerosis taken at autopsy of patients with coronary heart disease (n = 63). To detect apoptosis, the TUNEL method was used for calculating the apoptotic index (AI) in paraffin sections. Phenotyping the cells and test for expression of active caspase 3 (AC-3) and apoptosis-inducing factor (AIF) were performed using sections of coronary arteries stained by immunohistochemistry. Results: The study of apoptosis showed a significant (p <0.0001) increase in AI of SMC, EC, MF coronary arteries affected by atherosclerosis compared with unaffected vessels. Progression of the atherosclerotic process led to a decrease of AI of SMC and EC. Statistical analysis revealed moderate feedback between AI of SMC and neointimal thickness in the development of atherosclerotic lesions (r = -0,44, p <0.0001). The amount of the AC-positive SMC and EC at the stage of lipoidosis significantly (p <0.0001) exceeded the number of AC -positive SMC at the liposclerosis stage. Expression of AIF was observed in the nuclei of EC in the newly formed vessels of hyperplastic intima. Conclusions: Early atherosclerotic lesions of the coronary arteries are accompanied by intense apoptosis of SMC, EC and MF. The intensity of apoptosis of SMC and EC decreases with the development of atherosclerosis. Progression of intimal hyperplasia at the early stages of atherosclerosis is associated with reduced apoptosis of smooth muscle cells and enhanced macrophage apoptosis. Apoptosis of SMC and MF is caspase-dependent. Apoptosis of endothelial cells can occur both with the participation of caspases and independently of them (with AIF).

AB - : Anemia refers to manifestations of systemic inflammation in chronic obstructive pulmonary disease (COPD) and a factor aggravating the disease. Objective: To study gender characteristics of anemia in patients with COPD, to increase the effectiveness of treatment through the use of pharmacological agents erythropoietin and enteral iron. Materials and methods: The paper presents clinical data on 74 patients with stage II/III COPD and anemia along with results of the treatment of 49 patients who received standard therapy in addition to epoetin and Sorbiferdurules. Results: Patients with COPD much more frequently presented with iron deficiency anemia (IDA): 63 patients (85.1%) dominated by women (39 or 61.9% ) with men accounting only for 24 or 38.1% of the total. 11 patients (14.9%) had normochromic normocytic anemia with the parameters of anemia of chronic disease. The incidence of IDA in both groups correlated with age; it was largely a moderately severe condition that much more frequently occurred in women (24 out of 39 patients - 61,5%) than in men in whom the mild form of iron deficiency prevailed (14 of 24 patients - 58,3%). Conclusion: The overall prevalence of anemia concomitant with COPD was estimated at 26.5%. It was documented in44 women (33.7%), i.e. in each third patient. It occurred less frequently in men (30 or 20,7%). The presence of anemia deteriorates conditions of the patients, especially female ones, who more often suffer from shortness of breath, impaired general health status , fatigue, and depression; moreover, they more frequently need hospitalization. Correction of anemia with erythropoietin and iron preparations for the internal use can improve physical endurance of the patients, reduce cough intensity and shortness of breath, promote positive dynamics of physical tolerance for a prolonged period after the completion of antianemic therapy.

AB - The study included 74patients (22 men and 52 women) aged 48-75yr with type 2 diabetes mellitus (DM2). 62 (88,6%) of them had grade II hypertensive disease (grade II-III by the WHO/ISH-2010 classification), 46 (67%) presented with II- III class functional stable angina of effort, 7 patients survived myocardial infarction, two ones underwent coronary artery stenting. Patients of the main group (n=50) received oral hypoglycemic agents in combination with 1-exenatide (mimetic of glucagon-like peptide) in the form of two daily subcutaneous injections of 5 mcg for 1 month and 10 mcg during the next 5 months. Control patients (n=20) were given standard hypoglycemic therapy. Analysis of highly sensitive CRP demonstrated its increase to 3 mg/l and more in 72.8% of the patients that was responsible for the high risk of cardiovascular disorders. 22,8% of the patients had a CRP level 1,0-2,9 mg/l (moderate risk) and only in 4,2% it was lower than 1 mg/l (low risk). Six months of exenatide therapy resulted in normalization of glycemia, glycated hemoglobin and significant decrease of CRP level which suggested the improvement of the functional state of vascular endothelium due to reduction of chronic inflammation objectively reflected in the highly sensitive CRP level.

AB - Understanding and controlling the electrical response at a complex electrode electrolyte interface is key to the development of next-generation supercapacitors and other electrochemical devices. In this work, we apply a theoretical framework based on the effective screening medium and reference interaction site model to explore the role of electrical double-layer (EDL) formation and its interplay with quantum capacitance in graphene-based supercapacitors. In addition to pristine graphene, we investigate a novel C60 modified graphene supercapacitor material, which promises higher charge-storage capacity. Beyond the expected enhancement in the quantum capacitance, we find that the introduction of C60 molecules significantly alters the EDL response. These changes in EDL are traced to the interplay between surface morphology and charge localization character and ultimately dominate the overall capacitive improvement in the hybrid system. Our study highlights a complex interplay among surface morphology, electronic structure, and interfacial capacitance, suggesting general improvement strategies for optimizing carbon-based supercapacitor materials.

AB - A water-soluble meso-carboxy aryl substituted [18] heteroannulene (porphyrin) and its Zn-complex have been found to be viable in targeting alpha-Syn aggregation at all its key microevents, namely, primary nucleation, fibril elongation, and secondary nucleation, by converting the highly heterogeneous and cytotoxic aggresome into a homogeneous population of minimally toxic off-pathway oligomers, that remained unexplored until recently. With the EC50 and dissociation constants in the low micromolar range, these heteroannulenes induce a switch in the secondary structure of toxic prefibrillar on-pathway oligomers of alpha-Syn, converting them into minimally toxic nonseeding off-pathway oligomers. The inhibition of the aggregation and the reduction of toxicity have been studied in vitro as well as inside neuroblastoma cells. PMID- 30296046 TI - Amorphous Phosphorus-Doped Cobalt Sulfide Modified on Silicon Pyramids for Efficient Solar Water Reduction. AB - Cobalt sulfide (CoS x) functioned as a co-catalyst to accelerate the kinetics of photogenerated electrons on Si photocathode, leading to the enhancement of solar hydrogen evolution efficiency. By doping phosphorus heteroatoms, CoS x materials showed an improved catalytic activity because of superior surface area and quantity of active sites. Furthermore, increased vacancies in unoccupied electronic states were observed, as more phosphorus atoms doped into CoS x co catalysts. Although these vacant sites improved the capability to accept photoinduced electrons from Si photoabsorber, chemisorption energy of atomic hydrogen on catalysts was the dominant factor affecting in photoelectrochemical performance. We suggested that P-doped CoS x with appropriate doping quantities showed thermoneutral hydrogen adsorption. Excess phosphorus dopants in CoS x contributed to excessively strong adsorption with H atoms, causing the poor consecutive desorption ability of photocatalytic reaction. The optimal P-doped CoS x-decorated Si photocathode showed a photocurrent of -20.6 mA cm-2 at 0 V. Moreover, a TiO2 thin film was deposited on the Si photocathode as a passivation layer for improving the durability. The current density of 10 nm TiO2-modified photocathode remained at approximately -13.3 mA cm-2 after 1 h of chronoamperometry.

AB - Monitoring the properties and reactions of biomolecules at their interface has attracted ever-growing interest. Here, we propose an approach of infrared analysis technique that utilizes water molecule as a universal probe for in situ and label free monitoring of interfacial bioevents in aqueous solution with high sensitivity. The strong infrared (IR) signal of O-H stretching vibrations from the repelled water is used to sensitively reveal the kinetics of interfacial bioevents at molecular level based on the steric displacement of water using an attenuated total reflection-surface enhanced infrared absorption spectroscopy. Using interfacial immuno-recognition and DNA hybridization as demonstrations, water IR probe offers 26 and 34 times higher sensitivity and even 200 and 86 times lower detection limit for immunosensing and DNA sensing, respectively, as compared to the traditional IR molecular fingerprints. PMID- 30296049 TI - Selection of Appropriate Autoinducer Analogues for the Modulation of Quorum Sensing at the Host-Bacterium Interface. AB - Bacteria regulate a variety of phenotypes in response to their population density using quorum sensing (QS). This phenomenon is regulated by small molecule or peptide signals, the best characterized of which are the N-acyl l-homoserine lactones (AHLs) utilized by Gram-negative bacteria. As many QS-controlled phenotypes, notably pathogenicity and symbiosis, can profoundly impact host eukaryotes, there is significant interest in developing methods for modulating QS signaling and either ameliorating or augmenting these phenotypes. One strategy has been the use of non-native AHL analogues to agonize or antagonize specific AHL receptors. This approach is complicated, however, by the potential for prospective hosts to respond to both native AHLs and synthetic analogues. Accordingly, identifying AHL analogues with little or no activity toward eukaryotes is important in developing QS modulation as a strategy for the regulation of prokaryotic behaviors. Herein, we utilize the model plant Arabidopsis thaliana to characterize eukaryotic responses to a variety of synthetic AHL analogues to identify structural elements of existing scaffolds that may elicit responses in prospective hosts. Our results indicate that, while many of these compounds have no discernible effect on A. thaliana, some elicit strong phenotypes similar to those produced by auxin, a hormone involved in almost all aspects of plant development. We outline concentrations and chemical scaffolds that are ideal for deployment on plant hosts for the regulation of QS. This approach should be exportable to other eukaryotes for the selection of optimal AHL tools for the study of QS at the host-microbe interface.

AB - Alzheimer's disease (AD) is a neurodegenerative disorder with multifactorial pathogenesis. Monoamine oxidase (MAO) and acetylcholinesterase enzymes (AChE) are potential targets for the treatment of AD. A total of 15 new propargyl containing 4,6-diphenylpyrimidine derivatives were synthesized and screened for the MAO and AChE inhibition activities along with ROS production inhibition and metal chelation potential. All the synthesized compounds were found to be selective and potent inhibitors of MAO-A and AChE enzymes at nanomolar concentrations. VB1 was found to be the most potent MAO-A and BuChE inhibitor with IC50 values of 18.34 +/- 0.38 nM and 0.666 +/- 0.03 MUM, respectively. It also showed potent AChE inhibition with an IC50 value of 30.46 +/- 0.23 nM. Compound VB8 was found to be the most potent AChE inhibitor with an IC50 value of 9.54 +/- 0.07 nM and displayed an IC50 value of 1010 +/- 70.42 nM against the MAO-A isoform. In the cytotoxic studies, these compounds were found to be nontoxic to the human neuroblastoma SH-SY5Y cells even at 25 MUM concentration. All the compounds were found to be reversible inhibitors of MAO-A and AChE enzymes. In addition, these compounds also showed good neuroprotective properties against 6-OHDA- and H2O2 induced neurotoxicity in SH-SY5Y cells. All the compounds accommodate nicely to the hydrophobic cavity of MAO-A and AChE enzymes. In the molecular dynamics simulation studies, both VB1 and VB8 were found to be stable in the respective cavities for 30 ns. Thus, 4,6-diphenylpyrimidine derivatives can act as promising leads in the development of dual-acting inhibitors targeting MAO-A and AChE enzymes for the treatment of Alzheimer's disease.

AB - Chemically linked double network (DN) hydrogels display extraordinary mechanical attributes but mostly suffer from poor self-healing property and unsatisfactory biocompatibility due to the irreversible breaks in their chemical-linked networks and the use of toxic chemical cross-linking agents. To address these limitations, we developed a novel kappa-carrageenan/polyacrylamide (KC/PAM) DN hydrogel through a dual physical-cross-linking strategy, with the ductile, hydrophobically associated PAM being the first network, and the rigid potassium ion (K+) cross linked KC being the second network. The dual physically cross-linked DN (DPC-DN) hydrogels with optimized KC concentration exhibit excellent fracture tensile stress (1320 +/- 46 kPa) and toughness (fracture energy: 6900 +/- 280 kJ/m3), comparable to those fully chemically linked DN hydrogels and physically chemically cross-linked hybrid DN hydrogels. Moreover, because of their unique dual physical-cross-linking structures, the KC/PAM hydrogels also demonstrated rapid self-recovery, remarkable notch-insensitivity, self-healing capability, as well as excellent cytocompatibility toward stem cells. Accordingly, this work presents a new strategy toward fabricating self-repairing DPC-DN hydrogels with outstanding mechanical behaviors and biocompatibility. The new type of DN hydrogels demonstrates strong potentiality in many challenging biomedical applications such as artificial diaphragm, tendon, and cartilage. PMID- 30296053 TI - Duplex Lateral Flow Assay for the Simultaneous Detection of Yersinia pestis and Francisella tularensis. AB - High-risk pathogens such as Francisella tularensis and Yersinia pestis are categorized as highly hazardous organisms that can be used as biological weapons. Given the extreme infectivity of these potential biowarfare agents, a rapid, sensitive, cost-effective, and specific method for their detection is required. Here, we report the multiplexed amplification detection of genomic DNA from Francisella tularensis and Yersinia pestis. Amplification was achieved using isothermal recombinase polymerase amplification, exploiting tailed primers, followed by detection using a nucleic-acid lateral flow assay. Excess primers were removed using a novel fishing strategy, avoiding the use of postamplification purification that requires centrifugation and infers additional assay cost. The entire assay is completed in less than 1 h, achieving limits of detection of 243 fg (1.21 * 102 genome equivalent) and 4 fg (0.85 genome equivalent) for Francisella tularensis and Yersinia pestis, respectively. PMID- 30296054 TI - Molecular Targeted NIR-II Probe for Image-Guided Brain Tumor Surgery. AB - Optical imaging strategies for improving delineation of glioblastoma (GBM) is highly desired for guiding surgeons to distinguish cancerous tissue from healthy and precious brain tissue. Fluorescence imaging (FLI) in the second near-infrared window (NIR-II) outperforms traditional NIR-I imaging with better tissue penetration, higher spatial and temporal resolution, and less auto fluorescence and scattering. Because of high expression in GBM and many other tumors, urokinase Plasminogen Activator Receptor (uPAR) is an attractive and well proven target for FLI. Herein we aim to combine the benefit of a NIR-II fluorophore with a high affinity uPAR targeting small peptide. A targeted NIR-II fluorescent probe was developed by conjugating an in-house synthesized NIR-II fluorophore, CH1055, and a uPAR targeting peptide, AE105. To characterize the in vivo distribution and targeting properties, a dynamic imaging was performed in orthotopic GBM bearing nude mice ( n = 8). Additionally, fluorescence guided surgery of orthotopic GBM was performed in living animals. CH1055-4Glu-AE105 was easily synthesized with >75% yield and >98% HPLC evaluated purity. The retention time of the probe on analytical HPLC was 15.9 min and the product was verified by mass spectrometry. Dynamic imaging demonstrated that the uPAR targeting probe visualized orthotopic GBM through the intact skull with a tumor-to-background ratio (TBR) of 2.7 peaking at 96 h. Further, the orthotopic GBM was successfully resected in small animals guided by the NIR-II FLI. By using a small uPAR targeting NIR-II probe, FLI allows us to specifically image and detect GBM. A real-time imaging setup further renders FLI guided tumor resection, and the probe developed in this work is a promising candidate for clinical translation. PMID- 30296055 TI - Accelerated Carrier Relaxation through Reduced Coulomb Screening in Two Dimensional Halide Perovskite Nanoplatelets. AB - For high-speed optoelectronic applications relying on fast relaxation or energy transfer mechanisms, understanding of carrier relaxation and recombination dynamics is critical. Here, we compare the differences in photoexcited carrier dynamics in two-dimensional (2D) and quasi-three-dimensional (quasi-3D) colloidal methylammonium lead iodide perovskite nanoplatelets via differential transmission spectroscopy. We find that the cooling of excited electron-hole pairs by phonon emission progresses much faster and is intensity-independent in the 2D case. This is due to the low dielectric surrounding of the thin perovskite layers, for which the Frohlich interaction is screened less efficiently leading to higher and less density-dependent carrier-phonon scattering rates. In addition, rapid dissipation of heat into the surrounding occurs due to the high surface-to-volume ratio. Furthermore, we observe a subpicosecond dissociation of resonantly excited 1s excitons in the quasi-3D case, an effect which is suppressed in the 2D nanoplatelets due to their large exciton binding energies. The results highlight the importance of the surrounding environment of the inorganic nanoplatelets on their relaxation dynamics. Moreover, this 2D material with relaxation times in the subpicosecond regime shows great potential for realizing devices such as photodetectors or all-optical switches operating at THz frequencies. PMID- 30296056 TI - Assembly of Robust Holmium-Directed 2D Metal-Organic Coordination Complexes and Networks on the Ag(100) Surface. AB - We describe the formation of lanthanide-organic coordination networks and complexes under ultra-high-vacuum conditions on a clean Ag(100) surface. The structures comprise single Ho atoms as coordination centers and 1,4 benzenedicarboxylate (from terephtalic acid, TPA) as molecular linkers. Using low temperature scanning tunneling microscopy, we find two different chiral phases of surface-supported metal-organic structures incorporating Ho atoms. Density functional theory calculations can explain the structure of both binding motifs and give possible reasons for their varying formation under the respective Ho/TPA ratios, as well as deposition and annealing temperatures. Metal-ligand interactions drive the formation of cloverleaf-shaped mononuclear Ho-TPA4 complexes establishing supramolecular arrays stabilized through hydrogen bonding. A 2D lanthanide-organic reticulation is observed when changing the stoichiometry between the two building blocks. The combined insights from scanning tunneling microscopy and density functional theory reveal the relative stability, charge transfer, and bonding environment of both motifs. PMID- 30296057 TI - Molecular Colocalization Using Massive Gold Cluster Secondary Ion Mass Spectrometry. AB - We report on the ion emission from impacts of hypervelocity massive gold clusters for use in secondary ion mass spectrometry. Two massive gold clusters are considered, 520 keV Au4004+ and 1040 keV Au28008+. The emission of fragment ions and molecular ions is evaluated for a series of neat samples, glycine, phenylalanine, arginine, and gramicidin S. A 2 to 4-fold increase of molecular ion emission is observed from impacts of 1040 keV Au28008+ versus 520 keV Au4004+. Compared to impacts of 20 keV Ar2000+ and 20 keV (H2O)7000+ in static conditions, impacts of 1040 keV Au28008+ display a 6 to 9-fold increase in the number of detected molecular ions per projectile impact. To explain the increased emission of molecular species, we examine the size of the impact craters and calculate the ratio of molecular ions to fragment ions. The characterization of Au28008+ and the operating conditions of the gold liquid metal ion source are presented. PMID- 30296058 TI - Hierarchically Designed Ag@Ce6Mo10O39 Marigold Flower-Like Architectures: An Efficient Electrode Material for Hybrid Supercapacitors. AB - We facilely prepared silver nanoparticle-decorated Ce6Mo10O39 marigold flower like structures (Ag NPs@CM MFs) for use as an effective positive material in hybrid supercapacitors (HSCs). With the aid of ethylenediaminetetraacetic acid (EDTA) as a chelating agent, self-assembled CM MFs were synthesized by a single step hydrothermal method. When the electrochemical properties were tested in an aqueous alkaline electrolyte, the synthesized CM MFs with 0.15 g of EDTA exhibited a relatively high charge storage property (55.3 MUA h/cm2 at 2 mA/cm2) with a battery-type redox behavior. The high capacity performance is mainly because of the large surface area of the CM MFs, and the hierarchically connected nanoflakes provide wide open wells for rapid accessibility of electrolyte ions and enable fast transportation of electrons. A further improvement in electrochemical performance was achieved (62 MUA h/cm2 at 2 mA/cm2) by decorating Ag NPs on the surface of the CM MFs (i.e., Ag NPs@CM MFs), which is attributed to the increased electric conductivity. Considering the synergistic effect and the high electrochemical activity, Ag NPs@CM MFs were further employed as an effective positive electrode for the fabrication of pouch-type HSC with porous carbon (negative electrode) in an alkaline electrolyte. The HSC exhibited a high cell potential (1.5 V) with maximum energy and power densities of 0.0183 mW h/cm2 and 10.237 mW/cm2, respectively. The potency of HSC in practical applications was also demonstrated by energizing red and yellow light-emitting diodes as well as a three-point pattern torch light. PMID- 30296059 TI - Microfluidic-Based Genosensor To Detect Human Papillomavirus (HPV16) for Head and Neck Cancer. AB - High-risk human papillomavirus (HPV) infection, mainly with HPV16 type, has been increasingly considered as an important etiologic factor in head and neck cancers. Detection of HPV16 is therefore crucial for these types of cancer, but clinical tests are not performed routinely in public health systems owing to the high cost and limitations of the existing tests. In this article, we report on a potentially low-cost genosensor capable of detecting low concentrations of HPV16 in buffer samples and distinguishing, with high accuracy, head and neck cancer cell lines according to their HPV16 status. The genosensor consisted of a microfluidic device that had an active layer of a HPV16 capture DNA probe (cpHPV16) deposited onto a layer-by-layer film of chitosan and chondroitin sulfate. Impedance spectroscopy was the principle of detection utilized, leading to a limit of detection of 10.5 pM for complementary ssDNA HPV16 oligos (ssHPV16). The genosensor was also able to distinguish among HPV16+ and HPV16- cell lines, using the multidimensional projection technique interactive document mapping. Hybridization between the ssHPV16 oligos and cpHPV16 probe was confirmed with polarization-modulated infrared reflection-absorption spectroscopy, where PO2 and amide I and amide II bands from adenine and thymine were monitored. The electrical response could be modeled as resulting from an adsorption process represented in a Freundlich model. Because the fabrication procedures of the microfluidic devices and genosensors and the data collection and analysis can be implemented at low cost, the results presented here amount to a demonstration of possible routine screening for HPV infections. PMID- 30296060 TI - Insertions within the Saxitoxin Biosynthetic Gene Cluster Result in Differential Toxin Profiles. AB - The neurotoxin saxitoxin and related paralytic shellfish toxins are produced by multiple species of cyanobacteria and dinoflagellates. This study investigates the two saxitoxin-producing strains of Scytonema crispum, CAWBG524 and CAWBG72, isolated in New Zealand. Each strain was previously reported to have a distinct paralytic shellfish toxin profile, a rare observation between strains within the same species. Sequencing of the saxitoxin biosynthetic clusters ( sxt) from S. crispum CAWBG524 and S. crispum CAWBG72 revealed the largest sxt gene clusters described to date. The distinct toxin profiles of each strain were correlated to genetic differences in sxt tailoring enzymes, specifically the open-reading frame disruption of the N-21 sulfotransferase sxtN, adenylylsulfate kinase sxtO, and the C-11 dioxygenase sxtDIOX within S. crispum CAWBG524 via genetic insertions. Heterologous overexpression of SxtN allowed for the proposal of saxitoxin and 3' phosphoadenosine 5'-phosphosulfate as substrate and cofactor, respectively, using florescence binding assays. Further, catalytic activity of SxtN was confirmed by the in vitro conversion of saxitoxin to the N-21 sulfonated analog gonyautoxin 5, making this the first known report to biochemically confirm the function of a sxt tailoring enzyme. Further, SxtN could not convert neosaxitoxin to its N-21 sulfonated analog gonyautoxin 6, indicating paralytic shellfish toxin biosynthesis most likely occurs along a predefined route. In this study, we identified key steps toward the biosynthetic conversation of saxitoxin to other paralytic shellfish toxins. PMID- 30296061 TI - Ultrafine Particle Emissions from Natural Gas, Biogas, and Biomethane Combustion. AB - Biogas and biomethane (=purified biogas) are major renewable fuels that play a pivotal role in the evolving global energy economy. Here, we measure ultrafine particle (UFP; Dp (particle diameter) < 100 nm) emissions from the combustion of biomethane and biogas produced from five different representative sources: two food waste digesters, two dairy waste digesters, and one landfill. Combustion exhaust for each of these sources is measured from one or more representative sectors including electricity generation, motor vehicles, and household use. Results show that UFP emissions are similar when using biomethane and natural gas with similar sulfur and siloxane content. Approximately 70% of UFPs emitted from water heaters and cooking stoves were semivolatile, but 30% of the UFPs were nonvolatile and did not evaporate even under extremely high dilution conditions. Photochemical aging of biomethane combustion exhaust and natural gas combustion exhaust produced similar amounts of secondary organic aerosol (SOA) formation. The results of the current study suggest that widespread adoption of biogas and biomethane as a substitute for natural gas will not significantly increase ambient concentrations of primary and secondary UFPs if advanced combustion technology is used and the sulfur and siloxane content is similar for biogas/biomethane and natural gas. PMID- 30296063 TI - X-ray Crystallographic Structure of a Teixobactin Derivative Reveals Amyloid-like Assembly. AB - This paper describes the X-ray crystallographic structure of a derivative of the antibiotic teixobactin and shows that its supramolecular assembly through the formation of antiparallel beta-sheets creates binding sites for oxyanions. An active derivative of teixobactin containing lysine in place of allo enduracididine assembles to form amyloid-like fibrils, which are observed through a thioflavin T fluorescence assay and by transmission electron microscopy. A homologue, bearing an N-methyl substituent, to attenuate fibril formation, and an iodine atom, to facilitate X-ray crystallographic phase determination, crystallizes as double helices of beta-sheets that bind sulfate anions. beta Sheet dimers are key subunits of these assemblies, with the N-terminal methylammonium group of one monomer and the C-terminal macrocycle of the other monomer binding each anion. These observations suggest a working model for the mechanism of action of teixobactin, in which the antibiotic assembles and the assemblies bind lipid II and related bacterial cell wall precursors on the surface of Gram-positive bacteria. PMID- 30296064 TI - Direct One-Step Fluorescent Labeling of O-GlcNAc-Modified Proteins in Live Cells Using Metabolic Intermediates. AB - The modification of proteins with O-linked N-acetylglucosamine ( O-GlcNAc) by the enzyme O-GlcNAc transferase (OGT) has emerged as an important regulator of cellular physiology. Metabolic labeling strategies to monitor O-GlcNAcylation in cells have proven of great value for uncovering the molecular roles of O-GlcNAc. These strategies rely on two-step labeling procedures, which limits the scope of experiments that can be performed. Here, we report on the creation of fluorescent uridine 5'-diphospho- N-acetylglucosamine (UDP-GlcNAc) analogues in which the N acyl group of glucosamine is modified with a suitable linker and fluorophore. Using human OGT, we show these donor sugar substrates permit direct monitoring of OGT activity on protein substrates in vitro. We show that feeding cells with a corresponding fluorescent metabolic precursor for the last step of the hexosamine biosynthetic pathway (HBP) leads to its metabolic assimilation and labeling of O GlcNAcylated proteins within live cells. This one-step metabolic feeding strategy permits labeling of O-GlcNAcylated proteins with a fluorescent glucosamine nitrobenzoxadiazole (GlcN-NBD) conjugate that accumulates in a time- and dose dependent manner. Because no genetic engineering of cells is required, we anticipate this strategy should be generally amenable to studying the roles of O GlcNAc in cellular physiology as well as to gain an improved understanding of the regulation of OGT within cells. The further expansion of this one-step in-cell labeling strategy should enable performing a range of experiments including two color pulse chase experiments and monitoring OGT activity on specific protein substrates in live cells. PMID- 30296065 TI - Pretreatment with gamma-Valerolactone/[Mmim]DMP and Enzymatic Hydrolysis on Corncob and Its Application in Immobilized Butyric Acid Fermentation. AB - Corncob is a widely available raw material with high carbohydrate and low lignin content. To improve corncob conversion to the fermentable sugars, a novel method encompassing pretreatment using the gamma-valerolactone (GVL)/1-methyl-3 methylimidazolium dimethylphosphite ([Mmim]DMP) system integrated with cellulase hydrolysis was developed and optimized. It is confirmed that lignin was extracted efficiently after combined pretreatment and that the subsequent enzymatic saccharification efficiency could be significantly enhanced, resulting in the yield of 94.9% glucose from cellulose and 53.3% xylose from xylan, respectively. Furthermore, the above fermentable sugars were used as carbon source for Clostridium tyrobutyricum immobilized in macroporous Ca-alginate-lignin beads with the extracted lignin as the active ingredient to evaluate the fermentability of butyric acid. The results showed that high butyrate productivity of 0.47 g/L/h and yield of 0.45 g/g were obtained after 10 repeated batches of fermentation, demonstrating an effective process for the production of butyric acid from abundant corncob waste-biomass. PMID- 30296066 TI - Facile Mechanosynthesis of the Archetypal Zn-Based Metal-Organic Frameworks. AB - Mechanochemical methods have been successful in providing rapid access to a number of inorganic-organic functional materials under mild conditions. Recently, we demonstrated a novel mechanochemical strategy for metal-organic framework (MOF) preparation based on predesigned oxo-centered secondary building units. Herein, we develop this method for the facile preparation of the isoreticular MOF (IRMOF) family members based on a combination of an oxozinc amidate cluster, [Zn4(MU4-O)(NHOCPh)6], and selected ditopic aminoterephthalate and 4,4' biphenyldicarboxylate as well as tritopic 1,3,5-benzenetribenzoate ligands. The resulting IRMOF-3, IRMOF-10, and MOF-177 crystalline materials were characterized using powder X-ray diffraction, IR spectroscopy, scanning electron microscopy (SEM), and thermogravimetric analysis. We found that the character of the organic linker strongly affects the nature of the resulting MOF crystallites after activation processes. The SEM images demonstrate that IRMOF-3 formed microcrystallites in the range of 400-500 nm, while the two other materials exhibited microstructures of amorphous phases. The porosity of each sample was estimated by N2 sorption measurements at 77 K. These results provide an efficient and general method for the mechanosynthesis of Zn-based MOF materials using a predesigned oxozinc cluster. PMID- 30296067 TI - Mechanism for O-O Bond Formation via Radical Coupling of Metal and Ligand Based Radicals: A New Pathway. AB - Artificial photosynthesis carries promise to deliver abundant clean energy for the needs of a growing population. Deep mechanistic understanding is required to achieve rational design of fast and durable water oxidation catalysts. Here we provided first evidence for a new mechanism of the O-O bond formation via radical coupling of the oxidized metal?oxo of radicaloid character (RuIV?O) and ligand based radical ([ligand-NO]+* cation radical). O-O bond formation is facilitated via spin alignment and takes place via a virtually barrier less pathway inside the single metal complex. In situ reactive intermediate conversion was monitored by mass spectrometry, resonance Raman (RR) and EPR. Computational analysis have shown that the formation of [ligand-NO]+* happens at a lower overpotential than the formation of the [RuV?O(ligand)]3+ intermediate. Overall, the presented paradigm for O-O bond formation opens new opportunities for rational catalyst design.

AB - The N-glycan pattern of lactoperoxidase (LPO) from buffalo and goat milk was analyzed with the corresponding site of attachment. The enzyme was purified from whey on cation exchange chromatography, proteolyzed using chymotrypsin, and the resulting (glyco)peptides were directly analyzed on reverse phase ultrahigh performance liquid chromatography coupled to ESI-Q-TOF MS in tandem mode. N Glycans such as high mannose, complex, and hybrid types were identified in buffalo and goat LPO. Among sialylated complex and hybrid types, the terminal Neu5Ac linked to either LacNAc/LacdiNAc found exclusively in buffalo, whereas Neu5Gc linked to LacdiNAc was predominant in goat LPO. N-Glycans at Asn6 and Asn349 in buffalo LPO were completely core fucosylated, while these sites in goat LPO showed differential fucosylation. Differential occupancy was observed at Asn112 with or without nonfucosylated complex and hybrid types, whereas mainly high mannose glycans were found in Asn222 in both of the LPOs. The presence of glycan isomers in buffalo and goat LPO was also observed. Despite the presence of distinct complex and hybrid glycans, the common glycosylation features in buffalo and goat LPO were identified and are comparable with those of bovine LPO. This finding could be useful in exploring the beneficial role of these glycans as functional ingredients for food products. PMID- 30296069 TI - Electric Field Processing: Novel Perspectives on Allergenicity of Milk Proteins. AB - Milk proteins are being widely used in formulated foods as a result of their excellent technological, functional, and biological properties. However, the most representative proteins from casein and whey fractions are also recognized as major allergens and responsible for the prevalence of cow's milk protein allergy in childhood. Electroheating technologies based on thermal processing of food as a result of application of moderate electric fields, also known by ohmic heating (OH) or Joule effect, are establishing a solid foothold in the food industry. Currently, the influence of OH on allergenic aspects of milk proteins is under debate but still undisclosed. The occurrence of electrical effects on the protein structure and its function has already been reported; thus, the impact of OH over allergenicity should not be overlooked. On the basis of these recent findings, it is then relevant to speculate about the impact of this emergent technology on the potential allergenicity of milk proteins. PMID- 30296070 TI - Computation-Aided Rational Deletion of C-Terminal Region Improved the Stability, Activity, and Expression Level of GH2 beta-Glucuronidase. AB - In this study, computation-aided design on the basis of structural analysis was employed to rationally identify a highly dynamic C-terminal region that regulates the stability, expression level, and activity of a GH2 fungal glucuronidase from Aspergillus oryzae Li-3 (PGUS). Then, four mutants with a precisely truncated C terminal region in different lengths were constructed; among them, mutant D591 604 with a 3.8-fold increase in half-life at 65 degrees C and a 6.8 kJ/mol increase in Gibbs free energy showed obviously improved kinetic and thermodynamic stability in comparison to PGUS. Mutants D590-604 and D591-604 both showed approximately 2.4-fold increases in the catalytic efficiency kcat/ Km and 1.8 fold increases in the expression level. Additionally, the expression level of PGUS was doubled through a C-terminal region swap with bacterial GUS from E. coli (EGUS). Finally, the robust PGUS mutants D590-604 and D591-604 were applied in the preparation of glycyrrhetinic acid with 4.0- and 4.4-fold increases in concentration through glycyrrhizin hydrolysis by a fed-batch process. PMID- 30296071 TI - Scalable and Rechargeable Antimicrobial Coating for Food Safety Applications. AB - Environmental surfaces are common avenues for microbial contamination and transmission in food-processing establishments. We recently synthesized a polymer that combines both N-halamine and dopamine functional groups to form a novel antimicrobial coating material. A series of chemical (titration) and biological ("sandwich" and anti-inhabitation) tests were designed to prove the stability and functionality of as-developed coating material. Halamine-dopamine polymer-coated stainless-steel surface inactivated 6 log10 CFU of both Staphylococcus aureus and Escherichia coli O157:H7 under experimental detection limit within 10 min of contact time. After three "discharge-recharge" cycles, the surface maintained the same antimicrobial effectiveness; 60% of the surface chlorine remained after 10 "discharge-recharge" cycles. In addition, the coating thickness and chlorine content could be further tuned through adjusting the formulation of the coating. We also demonstrated that this coating material could be easily scaled up to apply on real food equipment parts through a spray-coating method. Thus our polymer material has great potential to produce a high-performance, low-cost, and easy-to-apply coating on food-associated environmental surfaces for food safety preventive-control applications.

AB - The aim of the bioassay-guided fractionation was the selection of the most potent group of compounds responsible for the protection of sunflower bee pollen grains. Synthesis of prospective antifungal polyamides of hydroxycinnamic acids was based on previous structural elucidation of ethanol soluble fraction by 1H,1H-PFG-COSY, 1H,13C-HSQC, FT-IR, FT-Raman, and LC-MS experiments. The main compounds found were tri- p-coumaroylspermidines accompanied by other HCAA of spermidine and putrescine. Several model HCAA derivatives were prepared to test their antifungal activity against widespread spoilage fungi ( A. niger 42 CCM 8189, F. culmorum DMF 0103, and P. verrucosum DMF 0023). A. niger CCM 8189 and F. culmorum DMF 0103 exhibited higher resistance to the antifungal effects of hydroxycinnamic acid amides, whereas P. verrucosum DMF 0023 was the most sensitive strain. It has been discovered the effect of HCAA polarity on the role of secondary metabolites in the microbial protection of pollen grains. The combination of bioassay-guided fractionation, structural elucidation, selection of prospective compounds, and their synthesis to determine their antifungal properties could be considered as an original approach.

AB - This work illustrates the reductive coupling of electron-rich aryl halides with tertiary alkyl halides under Ni-catalyzed cross-electrophile coupling conditions, which offers an efficient protocol for the construction of all carbon quaternary stereogenic centers. The mild and easy-to-operate reaction tolerates a wide range of functional groups. The utility of this method is manifested by the preparation of cyclotryptamine derivatives, wherein successful incorporation of 7-indolyl moieties is of particular interest as numerous naturally occurring products are composed of these key scaffolds. DFT calculations have been carried out to investigate the proposed radical chain and double oxidative addition pathways, which provide useful mechanistic insights into the part of the reaction that takes place in solution. PMID- 30296074 TI - Photoinduced Charge-Transfer Dynamics in WO3/BiVO4 Photoanodes Probed through Midinfrared Transient Absorption Spectroscopy. AB - The dynamics of photopromoted electrons in BiVO4, WO3, and WO3/BiVO4 heterojunction electrodes has been directly probed by transient absorption (TA) midinfrared (mid-IR) spectroscopy in the picosecond to microsecond time range. By comparison of the dynamics recorded with the two individual oxides at 2050 cm-1 with that of the heterojunction system after excitation at different wavelengths, electron-transfer processes between selectively excited BiVO4 and WO3 have been directly tracked for the first time. These results support the charge carrier interactions which were previously hypothesized by probing the BiVO4 hole dynamics through TA spectroscopy in the visible range. Nanosecond mid-IR TA experiments confirmed that charge carrier separation occurs in WO3/BiVO4 electrodes under visible-light excitation, persisting up to the microsecond time scale. PMID- 30296075 TI - Modification and Cross-Linking of Proteins by Glycolaldehyde and Glyoxal: A Model System. AB - Highly reactive intermediates of the Maillard reaction, such as glycolaldehyde and glyoxal, are precursors in the modification and cross-linking of proteins. Therefore, we investigated ribonuclease A modified by glycolaldehyde and glyoxal, separately. For the first time, various protein species derived by these aldehydes were successfully separated by ion-exchange chromatography and gel permeation chromatography. Highly cross-linked ribonuclease A was obtained in glycolaldehyde incubations. In contrast, glyoxal predominantly led to modified monomeric protein species. These results were verified by sodium dodecyl sulfate polyacrylamide gel electrophoresis and isoelectric focusing. Quantitation of mono and bivalent protein modifications of the isolated protein species led to a positive correlation between the degree of protein modification and the change of the isoelectric point and molecular weight, respectively. Glycolaldehyde is easily oxidized to glyoxal. However, significantly lower levels of bivalent glyoxal modifications were detected in glycolaldehyde versus glyoxal incubations (glyoxal-lysine dimer, 1.58 +/- 0.02 versus 2.86 +/- 0.04 mmol/mol of phenylalanine; glyoxal-lysine amide, 2.7 +/- 0.1 versus 5.6 +/- 0.1 mmol/mol of phenylalanine). In addition, a novel glycolaldehyde-specific lysine-lysine cross link was identified and putatively assigned as 1-(5-amino-5-carboxypentyl)-4-(5 amino-5-carboxypentyl-amino)pyridinium salt.

AB - Royal jelly, a natural product secreted by honeybees, contains several fatty acids, such as 10-hydroxy-2-decenoic acid (DE), and shows anti- and pro-apoptotic properties. 4-Hydroperoxy-2-decenoic acid ethyl ester (HPO-DAEE), a DE derivative, exhibits potent antioxidative activity; however, it currently remains unclear whether HPO-DAEE induces cancer-cell death. In the present study, treatment with HPO-DAEE induced human-lung-cancer-A549-cell death (52.7 +/- 10.2%) that was accompanied by DNA fragmentation. Moreover, the accumulation of intracellular reactive oxygen species (ROS, 2.38 +/- 0.1-fold) and the induction of proapoptotic CCAAT-enhancer-binding-protein-homologous-protein (CHOP) expression (18.4 +/- 4.0-fold) were observed in HPO-DAEE-treated cells. HPO-DAEE elicited CHOP expression and cell death were markedly suppressed by pretreatment with N-acetylcysteine (NAC), an antioxidant, by 2.40 +/- 1.57-fold and 5.7 +/- 1.6%, respectively. Pretreatment with 4-phenylbutyric acid (PBA), an inhibitor of endoplasmic reticulum stress, also suppressed A549-cell death (38.4 +/- 1.1%). Furthermore, we demonstrated the involvement of extracellular-signal-regulated protein kinase (ERK) and p38-related signaling in HPO-DAEE-elicited cell-death events. Overall, we concluded that HPO-DAEE induces A549-cell apoptosis through the ROS-ERK-p38 pathway and, at least in part, the CHOP pathway.

AB - An ideal system for stimuli-responsive and amphiphilic (block) polymers would be the copolymerization of aziridines with epoxides. However, to date, no copolymerization of these two highly strained three-membered heterocycles had been achieved. Herein, we report the combination of the living oxy- and azaanionic ring-opening polymerization of ethylene oxide (EO) and sulfonamide activated aziridines. In a single step, well-defined amphiphilic block copolymers are obtained by a one-pot copolymerization. Real-time 1H NMR spectroscopy revealed the highest difference in reactivity ratios ever reported for an anionic copolymerization (with r1 = 265 and r2 = 0.004 for 2-methyl- N-tosylaziridine/EO and r1 = 151 and r2 = 0.013 for 2-methyl- N-mesylaziridine/EO), leading to the formation of block copolymers with monomodal and moderate molecular weight distributions ( Mw/ Mn mostly <=1.3). The amphiphilic diblock copolymers were used to stabilize emulsions and to prepare polymeric nanoparticles by miniemulsion polymerization, representing a novel class of nonionic and responsive surfactants. In addition, this unique comonomer reactivity of activated-Az/EO allows fast access to multiblock copolymers, and we prepared the first amphiphilic penta- or tetrablock copolymers containing aziridines in only one or two steps, respectively. These examples render the combination of epoxide and aziridine copolymerizations via a powerful strategy for producing sophisticated macromolecular architectures and nanostructures. PMID- 30296078 TI - The Structural Arrangement and Relative Abundance of Aliphatic Units May Effect Long-Wave Absorbance of Natural Organic Matter as Revealed by 1H NMR Spectroscopy. AB - The objective of this study was to shed light on structural features which underlay intensity of long wave absorbance of natural organic matter (NOM) using 1H NMR spectroscopy. For this purpose, a set of the NOM samples was assembled from arctic and nonarctic sampling sites (the Kolyma river basin and Moscow region, respectively). It was to ensure a substantial difference in the humification degree of the isolated organic matter-the biogeochemical proxy of the long-wave absorbance of NOM. The assembled NOM set was analyzed using solution-state 1H NMR spectroscopy. The distribution of both backbone and exchangeable protons was determined using acquisition of spectra in three different solvents. The substantially higher contribution of nonfunctionalized aliphatic moieties CHn (e.g., materials derived from linear terpenoids, MDLT) in the arctic NOM samples was revealed as compared to the nonarctic ones. The latter were characterized with the higher content of CHalpha protons adjacent to electron-withdrawing groups which belong to carboxyl rich alicyclic moieties (CRAMs) or to aromatic constituents of NOM. We have calculated a ratio of CHn to CHalpha protons as a structural descriptor which showed significant inverse correlation to intensity of long wave absorbance assessed with a use of E4/ E6 ratio and the slope of absorption spectrum. The steric hindrance of aromatic chromophoric groups of the NOM ensemble by bulky nonfunctionalized aliphatic moieties (e.g., MDLT) was set as a hypothesis for explanation of this phenomenon. The bulky aliphatics might increase a distance between the interacting groups resulting in inhibition of electronic (e.g., charge-transfer) interactions in the NOM ensemble. The obtained relationships were further explored using Fourier transform mass spectrometry as complementary technique to 1H NMR spectroscopy. The data obtained on correlation of molecular composition of NOM with 1H NMR data and optical properties were very supportive of our hypothesis that capabilities of NOM ensemble of charge transfer interactions can be dependent on structural arrangement and relative abundance of nonabsorbing aliphatic moieties.

AB - Avian egg white is essential for protecting and nourishing bird embryos during their development. Being produced in the female magnum, variability in hen oviduct gene expression may affect egg white composition in domestic chickens. Since traditional poultry breeds may represent a source of variation, in the present study we describe the egg white proteome (mass spectrometry) and corresponding magnum transcriptome (high-throughput sequencing) for 20 hens from five domestic fowl breeds (large breeds: Araucana, Czech golden pencilled, Minorca; and small breeds: Booted bantam, Rosecomb bantam). In total, we identified 189 egg white proteins and 16391 magnum-expressed genes. The majority of egg white protein content comprised proteins with an antimicrobial function. Despite general similarity, Between-class Principal Component Analysis revealed significant breed-specific variability in protein abundances, differentiating especially small and large breeds. Though we found strong association between magnum mRNA expression and egg white protein abundance across genes, coinertia analysis revealed no transcriptome/proteome costructure at the individual level. Our study is the first to show variation in protein abundances in egg white across chicken breeds with potential effects on egg quality, biosafety, and chick development. The observed interindividual variation probably results from post transcriptional regulation creating a discrepancy between proteomic and transcriptomic data.

AB - A diblock copolymer containing a strapped calix[4]pyrrole-based ion pair recognition subunit has been synthesized via RAFT polymerization. As prepared, the polymer is hydrophobic and devoid of any particular morphological form. However, upon ion pair complexation, the copolymer self-assembles to generate reverse micelles in organic media. The reverse micelles formed in this way may be used to extract alkali cation and cesium halide anion salts from an aqueous source into an organic receiving phase. The polymer proved more effective as an extractant than the corresponding free ion pair receptor.

AB - Core-shell nanofibers were fabricated by electrospinning of gel-like corn oil emulsions stabilized by gelatin. The oil-in-water (O/W) emulsions satisfied the Herschel-Bulkley rheological model and showed shear-thinning and predominantly elastic gel behaviors. The increasing oil fractions (phi) ranging from 0 to 0.6 remarkably increased the apparent viscosity and then led to an increase in the average diameter and encapsulation efficiency of electrospun fibers. Core-shell structured fibers by emulsion electrospinning were observed in transmission electron microscopy (TEM) images. The encapsulated oil was found to randomly distribute as core, especially inside the beads. The binding of corn oil to gelatin was mainly driven by noncovalent forces. These core-shell fibers at various phi values (phi = 0.2, 0.4, 0.6, and 0.8) showed a high thermal decomposition stability upon heating to 250 degrees C, and the denaturation temperatures were 85.32 degrees C, 77.97 degrees C, 82.99 degrees C, and 87.25 degrees C, respectively. The corn oil encapsulated in emulsion-based fiber mats had good storage stability during 5 days. These results contributed to a good understanding of emulsion electrospinning of food materials for potential applications in bioactive encapsulation, enzyme immobilization, and active food packaging. PMID- 30296082 TI - Antiradical Activity and Mechanism of Coumarin-Chalcone Hybrids: Theoretical Insights. AB - In view of the multifunctional features of coumarins and chalcones, coumarin chalcone hybrids have attracted much attention in recent years. Herein, the free radical scavenging activities of a series of coumarin-chalcone hybrids were investigated using the density functional theory (DFT) method. Three main reaction mechanisms were explored: hydrogen atom transfer (HAT), electron transfer followed by proton transfer (SET-PT), and sequential proton loss electron transfer (SPLET). Thermodynamic descriptors associated with these mechanisms were calculated in the gas phase and solvents. The results demonstrate that the predicted antioxidant efficiencies are generally in accordance with the experimental results. HAT is proposed as the thermodynamically favored mechanism in the gas phase and nonpolar solution, while SPLET is preferred in polar media. Our results indicate that compound MPHCC possesses potential for inactivating free radicals via double HAT and double SPLET mechanisms depending upon the polarity of environment. In addition, the SPLHAT mechanism provides an alternative pathway to HAT and SPLET for radical scavenging by MPHCC and OPHCC. The results confirmed the crucial role of hydroxyl groups on the chalcone moiety in trapping radicals. 4'-OH in the catechol group is proposed as the primary target for radical attack. PMID- 30296084 TI - Simple Entropy Terms for End-Point Binding Free Energy Calculations. AB - We introduce a number of computationally inexpensive modifications to the MM/PBSA and MM/GBSA estimators for binding free energies, which are based on average receptor-ligand interaction energies in simulations of a noncovalent complex, to improve the treatment of entropy: second- and higher-order terms in a cumulant expansion and a confining potential on ligand external degrees of freedom. We also consider a filter for snapshots where ligands have drifted from the initial binding pose. The variations were tested on six sets of systems for which binding modes and free energies have previously been experimentally determined. For some data sets, none of the tested estimators led to results significantly correlated with measured free energies. In data sets with nontrivial correlation, a ligand RMSD cutoff of 3 A and a second-order truncation of the cumulant expansion was found to be comparable or better than the average interaction energy by several statistical metrics.

Avibactam, approved by FDA in 2015, is the first of a new class of BLIs called diazabicyclooctanes, or "DBOs". This class has much broader coverage than clavulanic acid but can only be administered by intravenous injection. Herein, we describe the synthesis and testing of the first approved BLI to be rendered orally bioavailable since clavulanic acid (1984). PMID- 30296087 TI - Calculating Optical Rotatory Dispersion Spectra in Solution Using a Smooth Dielectric Model. AB - The calculation of specific rotation of molecules in solution is probed at the coupled cluster (CC) level utilizing a continuum dielectric model based on a definition of the dielectric permittivity as a smooth function of electron density. Solvation effects are captured through polarization of Hartree-Fock (HF) molecular orbitals before subsequent calculations with the coupled cluster singles and doubles (CCSD) method. For the challenging ( S)-methyloxirane molecule, CCSD specific rotations yield an incorrect sign for the rotation in water, and the continuum model is unable to predict the wide variations in the optical rotatory dispersion (ORD) curves seen for nonpolar solvents of similar dielectric constant. In two molecules, (1 S,4 S)-norbornenone and ( S)-2 chloropropionitrile, specific rotations computed with CCSD in conjunction with implicit solvent fail to provide solvent shifts of the correct order of magnitude, indicating that the solvent response is a major contribution to the overall solvation effect. PMID- 30296088 TI - Flat-Histogram Monte Carlo as an Efficient Tool To Evaluate Adsorption Processes Involving Rigid and Deformable Molecules. AB - Monte Carlo simulations are the foundational technique for predicting thermodynamic properties of open systems where the process of interest involves the exchange of particles. Thus, they have been used extensively to computationally evaluate the adsorption properties of nanoporous materials and are critical for the in silico identification of promising materials for a variety of gas storage and chemical separation applications. In this work we demonstrate that a well-known biasing technique, known as "flat-histogram" sampling, can be combined with temperature extrapolation of the free energy landscape to efficiently provide significantly more useful thermodynamic information than standard open ensemble MC simulations. Namely, we can accurately compute the isosteric heat of adsorption and number of particles adsorbed for various adsorbates over an extremely wide range of temperatures and pressures from a set of simulations at just one temperature. We extend this derivation of the temperature extrapolation to adsorbates with intramolecular degrees of freedom when Rosenbluth sampling is employed. Consequently, the working capacity and isosteric heat can be computed for any given combined temperature/pressure swing adsorption process for a large range of operating conditions with both rigid and deformable adsorbates. Continuous thermodynamic properties can be computed with this technique at very moderate computational cost, thereby providing a strong case for its application to the in silico identification of promising nanoporous adsorbents.

AB - We examine vibronic coupling in the first five electronic states (X2Pig-A2Piu B2Sigmag+-C2Sigmau+-D2Pig-E2Piu) of dicyanodiacetylene radical cation (C6N2*+) in this article. Prompted by the prediction of its existence in the astrophysical environment, the vibronic band structure of these electronic states of C6N2*+ has been probed in spectroscopic measurements in laboratory by various groups. Inspired by numerous experimental data, we undertook the task of investigating topographical details of electronic potential energy surfaces, their coupling mechanism and nuclear dynamics on them. The degenerate Pi electronic states of this radical are prone to Renner-Teller instability, and in addition symmetry allowed Sigma-Pi and Pi-Pi vibronic coupling is expected to play crucial role in the detailed vibronic structure of each of the above electronic states. A vibronic coupling model is developed here and first-principles nuclear dynamics study is carried out employing quantum mechanical methods. The vibronic band structure thus calculated is compared with experimental results and the progressions are identified and assigned. The nonradiative internal conversion dynamics among electronic states is also examined and discussed in relation to the various coupling of electronic states.

AB - A simple molecular probe displays highly selective turn-on response toward NO by the unprecedented NO-induced formation of a 1,2,3,4-oxatriazole ring exhibiting no interference from various endogenous biomolecules including DHA, AA, etc. Kinetics of the reactions between NO and the probe provide a mechanistic insight into the formation of 1,2,3,4-oxatriazole which showed that, though initially 1,2,3,4-oxatriazole is formed and extractable in solid form, it exists in equilibrium with the ring opened azide form which ultimately hydrolyzed and converted to carboxylic acid and nitrate. The reaction displays second-order dependence on [NO] and first-order on [Probe]. The probe is water-soluble, cell permeable, and noncytotoxic and appropriates for live cell imaging. This constitutes the first report where there is a direct evidence of NO-induced ring closing reaction of an acyl hydrazide moiety leading to the formation of 1,2,3,4 oxatriazole.

AB - Layered transition metal dichalcogenide (TMDC) materials have received great attention because of their remarkable electronic, optical, and chemical properties. Among typical TMDC family members, monolayer MoS2 has been considered a next-generation semiconducting material, primarily due to a higher carrier mobility and larger band gap. The key enabler to bring such a promising MoS2 layer into mass production is chemical vapor deposition (CVD). During CVD synthesis, gas-phase sulfidation of MoO3 is a key elementary reaction, forming MoS2 layers on a target substrate. Recent studies have proposed the use of gas phase H2S precursors instead of condensed-phase sulfur for the synthesis of higher-quality MoS2 crystals. However, reaction mechanisms, including atomic level reaction pathways, are unknown for MoO3 sulfidation by H2S. Here, we report first-principles quantum molecular dynamics (QMD) simulations to investigate gas phase sulfidation of MoO3 flake using a H2S precursor. Our QMD results reveal that gas-phase H2S molecules efficiently reduce and sulfidize MoO3 through the following reaction steps: Initially, H transfer occurs from the H2S molecule to low molecular weight Mo xO y clusters, sublimated from the MoO3 flake, leading to the formation of molybdenum oxyhydride clusters as reaction intermediates. Next, two neighboring hydroxyl groups on the oxyhydride cluster preferentially react with each other, forming water molecules. The oxygen vacancy formed on the Mo-O-H cluster as a result of this dehydration reaction becomes the reaction site for subsequent sulfidation by H2S that results in the formation of stable Mo-S bonds. The identification of this reaction pathway and Mo-O and Mo-O-H reaction intermediates from unbiased QMD simulations may be utilized to construct reactive force fields (ReaxFF) for multimillion-atom reactive MD simulations.

PMID- 30296094 TI - Connecting the Dunham Expansion to the Dissociation Limit for Interatomic Potentials: Application to Lennard-Jones m- n Potentials. AB - Dunham generated the expansion for energy levels of a rotating, vibrating diatomic molecule from an expansion of the potential about the equilibrium position. For partition functions, however, the energy levels are needed all the way to dissociation. Analytic Morse oscillator energies are not very useful because the exponential decay of the Morse potential is much too short-ranged for any physical system. The longer-range Lennard-Jones 12-6 potential could be used, but quantum energies have not previously been conveniently fit. I show how Dunham coefficients begin a set of asymptotic functions for any interaction potential, one function arising from each successive term in the WKB expansion. I apply this to the family of Lennard-Jones m- n (LJ m- n) potentials with an R-m repulsive term and R-n attractive term ( m > n) and demonstrate how m can be used as a parameter to adjust either the equilibrium distance or harmonic frequency. I present an empirical parametrization of LJ m- n vibrotor energies starting with Dunham coefficients generated from four terms in the WKB expansion. This information is combined with data from numerically solved energies and asymptotic limits to fit the functions all the way to dissociation. One can also treat exp-6 and similar model potentials with different repulsive parts using the same method because the expansion form is controlled by the long-range part of the potential. PMID- 30296092 TI - Shear Viscosity Computed from the Finite-Size Effects of Self-Diffusivity in Equilibrium Molecular Dynamics. AB - A method is proposed for calculating the shear viscosity of a liquid from finite size effects of self-diffusion coefficients in Molecular Dynamics simulations. This method uses the difference in the self-diffusivities, computed from at least two system sizes, and an analytic equation to calculate the shear viscosity. To enable the efficient use of this method, a set of guidelines is developed. The most efficient number of system sizes is two and the large system is at least four times the small system. The number of independent simulations for each system size should be assigned in such a way that 50%-70% of the total available computational resources are allocated to the large system. We verified the method for 250 binary and 26 ternary Lennard-Jones systems, pure water, and an ionic liquid ([Bmim][Tf2N]). The computed shear viscosities are in good agreement with viscosities obtained from equilibrium Molecular Dynamics simulations for all liquid systems far from the critical point. Our results indicate that the proposed method is suitable for multicomponent mixtures and highly viscous liquids. This may enable the systematic screening of the viscosities of ionic liquids and deep eutectic solvents.

AB - In classical laser fields with frequencies resonant with the electronic excitation in molecules, it is by now known that conical intersections are induced by the field and are called light-induced conical intersections (LICIs). As optical cavities have become accessible, the question arises whether their quantized modes could also lead to the appearance of LICIs. A theoretical framework is formulated for the investigation of LICIs of diatomics in such quantum light. The eigenvalue spectrum of the dressed states in the cavity is studied, putting particular emphasis on the investigation of absorption spectra of the Na2 molecule, that is, on the transitions between dressed states, measured by employing a weak probe pulse. The dependence of the spectra on the light matter coupling strength in the cavity and on the frequency of the cavity mode is studied in detail. The computations demonstrate strong nonadiabatic effects caused by the appearing LICI. PMID- 30296096 TI - Insight into The Nature of Rim Bonds in Coronene. AB - Coronene is known in chemistry as an aromatic or even superaromatic molecule while it has 24 pi-electrons which does not conform to the 4 n + 2 Huckel's rule. Chemical bonding description of it is not settled in chemistry and five models were reported in the literature. According to our model, coronene has two concentric pi-systems responsible for aromaticity inside of the molecule. In addition to that there are six peripheral 2c-2e pi-bonds, which makes coronene aliphatic/aromatic at the same time. However, recent experiments and calculations put in question the presence of peripheral pi-bonds. In order to resolve this issue, we computationally studied reaction mechanism of the Cl2 molecule with C2H4, C6H6, and C24H12. As it turned out, coronene behaves in a way similar to ethylene by adding Cl2 molecule. Thus, it proves that coronene indeed has peripheral double bonds which is also consistent with its experimental geometrical features. Our chemical bonding model allows to identify the most reactive atoms in coronene and other PAHs; therefore, it is a matter of importance for combustion and soot formation studies.

AB - The generalized Einstein equation for the viscosity of a dispersion/suspension, MU = (1 + alphafphi)MU0, where MU0 is the liquid viscosity, phi is the solid volume fraction, and alphaf is a coefficient, is applied to the viscosity of a nanofluid lubricant. The coefficient of lubricated friction in the hydrodynamic regime is proportional to the viscosity of the lubricant. Therefore, an equation for the coefficient of friction with nanofluid lubrication can be formulated. We present such an equation and show its validity for common types of bearings (journal, rolling, and ball bearings). The equation, which may be viewed as one of nanofriction laws, is compared with experimental results for WS2 nanoparticle enhanced oil lubrication, showing agreement within 7% accuracy. PMID- 30296099 TI - Study of Short-Chain Alcohol and Alcohol-Water Adsorption in MEL and MFI Zeolites. AB - In this paper, we present a comparative study of the adsorption behavior of short chain alcohols (pure and in aqueous solution) into silicalite-1 (MFI-type zeolite) and silicalite-2 (MEL-type zeolite). For quite some time, silicalite-1 has been the reference material to address the problem of adsorptive-based separation, mostly for hydrocarbon mixtures. Interestingly, being structurally close to silicalite-1, adsorption studies using silicalite-2 are scarce and to the best of our knowledge, a comparative study of their behavior for alcohol water mixtures has not been published to date. We have here resorted to molecular simulation techniques to analyze the adsorption and diffusion phenomena in both zeolites at 25 and 50 degrees C for pure methanol, ethanol, 1-butanol, and water, and for some relevant compositions of alcohol/water mixtures. In addition to the dilute regime in the mixture, our study ranges from intermediate alcohol concentrations to alcohol-rich phases, relevant to alcohol purification processes. Besides, we have performed volumetric and calorimetric measurements of single-component adsorption of alcohols in pure silica MEL zeolite, which were used to validate the model potentials used in the simulations. We observe that the zigzag channels of MFI zeolite are most likely responsible for its somewhat higher affinity for alcohols. This leads to higher adsorption selectivities when compared to those of MEL zeolite. We have also found that the choice of water model strongly conditions water coadsorption into the zeolites and subsequently the predictions of the adsorbent's selectivity in alcohol/water systems. Despite considerable differences for adsorbed pure components, diffusivities of alcohol and water adsorbed from mixtures are relatively similar, as a consequence of the strong hydrogen bonds between hydroxyl groups and water.

AB - Hybrid imogolite aluminosilicate nanotubes with methylated internal surface can be obtained by introduction of the corresponding organosilane during their synthesis. However, similarly to pristine imogolite, a number of side products, including proto-imogolite (open-imoLS), allophanes, and aluminum hydroxides, are formed, which ultimately impact on the properties of the dispersions. In order to minimize the proportion of these side products, we have here systematically explored the impact of the initial Si/Al ratio on the content of hybrid imogolite dispersions before and after dialysis. By combining cryo-transmission electron microscopy, inductively coupled plasma mass spectrometry, infrared spectroscopy, and small-angle X-ray scattering, we evidenced that the Si/Al ratio has a large impact on the formation of aluminum hydroxides that can be minimized with a slight excess of Si precursor. However, a large excess of Si is detrimental to the reaction yield leading to an important proportion of proto-imogolite. We propose that the optimal Si/Al ratio of ca. 0.6 can both minimize the proportion of aluminum hydroxides and proto-imogolite. These results suggest that the dynamic and therefore reactive character of imogolite dispersions may have been so far underlooked. PMID- 30296101 TI - DLVO Interaction Energies for Hollow Particles: The Filling Matters. AB - A thorough knowledge of the interaction energy between a hollow particle (HP) and a surface or between two HPs is critical to the optimization of HP-based products and assessing the environmental risks of HPs and HP-associated pollutants. The van der Waals (vdW) energy between a HP and a surface is often calculated by subtracting the vdW energies of the inner and outer HP geometries. In this study, we show that this subtraction method is only valid when the interior and exterior fluids are the same, for example, for water-filled HPs (WHPs) dispersed in an aqueous solution. Expressions were developed to calculate the vdW energies for HPs whose interiors were filled with air (AHPs). The vdW energies were then calculated between a planar surface and a spherical or cylindrical WHP and AHP, and between WHPs or AHPs. The vdW attraction between a surface and a WHP was decreased at large separation distances compared to solid particles, and this reduced the depth of the secondary minimum. In contrast, the vdW attraction for AHPs and a surface was significantly reduced at all separation distances, and even became repulsive for thin shells, and this inhibited both primary and secondary minimum interactions. The vdW attraction between WHPs decreased with increasing shell thicknesses, and this reduced aggregation in both primary and secondary minima. In contrast, aggregation of AHPs was increased in both minima with decreasing shell thicknesses because of an increase in vdW attraction. Our theoretical calculations show the evolution of vdW and total interaction energies for HPs with different interior fluids and shell thicknesses. These results help explain various experimental observations such as inhibited attachment and favorable aggregation for AHPs (e.g., carbon nanotubes) and favorable bubble coalescence.

The solvent repacking Monte Carlo method and a new variation were used to exchange varying numbers and types of particles under conditions of fixed particle fugacities, allowing efficient sampling of impurity particle distributions even within the bulk solid. Measurements of GB stiffness depression arising from the impurities were made via the capillary fluctuation method and found to agree with calculations based on the Gibbs adsorption isotherm, providing a test of the internal consistency of the results. The dependence of the excess concentration at the GB on factors, including impurity size (diameter ratios lambda = 0.5-4 times the majority host particle diameter), impurity concentration, grain misorientation angle, and packing pressure, was studied. In general, the affinity of impurity particles for GB increased with the difference between their size and the host particles, and varied with grain misorientation angle with a dependence reflecting the excess free area at the GB. Impurities with lambda = 4 were exceptions to both these trends, due to their ability to substitute efficiently for six-coordinate host particles within the bulk and for five-coordinate host particles at dislocations in the grain boundaries. Comparison with results from an experimental study of mixed colloidal monolayers raises questions about how kinetic effects during grain coarsening might produce less impurity segregation to the GB than equilibrium exchange.

AB - Coimmobilization of functional, nanosized assemblies broadens the possibility to engineer dually functionalized active surfaces with a nanostructured texture. Surfaces decorated with different nanoassemblies, such as micelles, polymersomes, or nanoparticles are in high demand for various applications ranging from catalysis, biosensing up to antimicrobial surfaces. Here, we present a combination of bio-orthogonal and catalyst-free strain-promoted azide-alkyne click (SPAAC) and thiol-ene reactions to simultaneously coimmobilize various nanoassemblies; we selected polymersome-polymersome and polymersome-micelle assemblies. For the first time, the immobilization method using SPAAC reaction was studied in detail to attach soft, polymeric assemblies on a solid support. Together, the SPAAC and thiol-ene reactions successfully coimmobilized two unique self-assembled structures on the surfaces. Additionally, poly(dimethylsiloxane) (PDMS)-based polymersomes were used as "ink" for direct immobilization from a PDMS-based microstamp onto a surface creating locally defined patterns. Combining immobilization reactions has the advantage to attach any kind of nanoassembly pairs, resulting in surfaces with "desired" interfacial properties. Different nanoassemblies that encapsulate multiple active compounds coimmobilized on a surface will pave the way for the development of multifunctional surfaces with controlled properties and efficiency.

AB - Lithium metal is an ideal material for high-energy, cost-effective rechargeable energy storage systems. The thermodynamically unfavorable solid-liquid interface between the lithium metal and organic electrolyte necessitates the formation of an interlayer (SEI) which is known to have significant impact on lithium morphologies. Less well understood is the impact of the current collector substrate on the morphology of electrodeposited lithium. Here we report on the morphology of electrodeposited lithium as a function of the chemical pretreatments of the working electrode. We find that a copper substrate pretreatment with acidic solutions (sulfuric, oxalic, or acetic acid) results in the deposition of close-packed lithium columns with a uniform diameter. A controlled study of the pre-electrodeposited copper surface indicates that the formation of a 5-8 nm thick LiF protective layer on copper substrate from a chemical reaction between adsorbed surface water layer in acidic solutions and LiPF6 electrolyte is the key process in the electrochemical growth of lithium columns. We anticipate that this simple chemical approach can be generalized as a scalable, low-cost, additive-free substrate treatment method for depositing a LiF protective layer, broadly applicable in the development of uniform lithium films. PMID- 30296107 TI - Ultrathin van der Waals Metalenses. AB - Ultrathin and flat optical lenses are essential for modern optical imaging, spectroscopy, and energy harvesting. Dielectric metasurfaces comprising nanoscale quasi-periodic resonator arrays are promising for such applications, as they can tailor the phase, amplitude, and polarization of light at subwavelength resolution, enabling multifunctional optical elements. To achieve 2pi phase coverage, however, most dielectric metalenses need a thickness comparable to the wavelength, requiring the fabrication of high-aspect-ratio scattering elements. We report ultrathin dielectric metalenses made of van der Waals (vdW) materials, leveraging their high refractive indices and the incomplete phase design approach to achieve device thicknesses down to ~lambda/10, operating at infrared and visible wavelengths. These materials have generated strong interest in recent years due to their advantageous optoelectronic properties. Using vdW metalenses, we demonstrate near-diffraction-limited focusing and imaging and exploit their layered nature to transfer the fabricated metalenses onto flexible substrates to show strain-induced tunable focusing. Our work enables further downscaling of optical elements and opportunities for the integration of metasurface optics in ultraminiature optoelectronic systems. PMID- 30296108 TI - Avalanche Behavior in Creep Failure of Disordered Materials. AB - We present a mesoscale elastoplastic model of creep in disordered materials, which considers temperature-dependent stochastic activation of localized deformation events that are coupled by internal stresses, leading to collective avalanche dynamics. We generalize this stochastic plasticity model by introducing damage in terms of a local strength that decreases, on statistical average, with increasing local plastic strain. The model captures failure in terms of strain localization in a catastrophic shear band concomitant with a finite-time singularity of the creep rate. The statistics of avalanches in the run-up to failure is characterized by a decreasing avalanche exponent tau that, at failure, approaches the value tau=1.5 typical of a critical branching process. The average avalanche rate exhibits an inverse Omori law as a function of time to failure. The distribution of interavalanche times turns out to be consistent with the epidemic-type aftershock sequences (ETAS) model of earthquake statistics. PMID- 30296109 TI - Enhancing the Radiation Resistance of Undulator Permanent Magnets by Tilting the Easy Axis of Magnetization. AB - The undulator is a magnetic device usually consisting of a series of rare-earth permanent magnets (REPMs) arranged to generate a sinusoidal magnetic field, and is installed in synchrotron radiation and free electron laser facilities to periodically deflect high-energy electrons. Because the undulator is operated under a high-radiation environment, it is important to take possible measures to avoid the quality degradation, in particular the radiation damage of REPMs. We present a simple scheme to enhance the radiation resistance of REPMs in undulators, in which the easy axis of each REPM is tilted by 45 degrees . Experimental studies have revealed that the radiation resistance of REPMs in this configuration is enhanced by an order of magnitude compared to that in the conventional undulator. PMID- 30296110 TI - Observation of Nonlocal Heat Flux Using Thomson Scattering. AB - Nonlocal heat flux was measured in laser-produced coronal plasmas using a novel Thomson scattering technique. The measured heat flux was smaller than the classical values inferred from the measured plasma conditions in regions with large temperature gradients and agreed with classical values for weak gradients. Vlasov-Fokker-Planck simulations self-consistently calculated the electron distribution functions used to reproduce the measured Thomson scattering spectra and to determine the heat flux. Multigroup nonlocal simulations overestimated the measured heat flux. PMID- 30296111 TI - Erratum: GW170104: Observation of a 50-Solar-Mass Binary Black Hole Coalescence at Redshift 0.2 [Phys. Rev.

PMID- 30296112 TI - Hybrid Systems for the Generation of Nonclassical Mechanical States via Quadratic Interactions. AB - We present a method to implement two-phonon interactions between mechanical resonators and spin qubits in hybrid setups, and show that these systems can be applied for the generation of nonclassical mechanical states even in the presence of dissipation. In particular, we demonstrate that the implementation of a two phonon Jaynes-Cummings Hamiltonian under coherent driving of the qubit yields a dissipative phase transition with similarities to the one predicted in the model of the degenerate parametric oscillator: beyond a certain threshold in the driving amplitude, the driven-dissipative system sustains a mixed steady state consisting of a "jumping cat," i.e., a cat state undergoing random jumps between two phases. We consider realistic setups and show that, in samples within reach of current technology, the system features nonclassical transient states, characterized by a negative Wigner function, that persist during timescales of fractions of a second. PMID- 30296114 TI - Many-Body Quantum Interference and the Saturation of Out-of-Time-Order Correlators. AB - Out-of-time-order correlators (OTOCs) have been proposed as sensitive probes for chaos in interacting quantum systems. They exhibit a characteristic classical exponential growth, but saturate beyond the so-called scrambling or Ehrenfest time tau_{E} in the quantum correlated regime. Here we present a path-integral approach for the entire time evolution of OTOCs for bosonic N-particle systems. We first show how the growth of OTOCs up to tau_{E}=(1/lambda)logN is related to the Lyapunov exponent lambda of the corresponding chaotic mean-field dynamics in the semiclassical large-N limit. Beyond tau_{E}, where simple mean-field approaches break down, we identify the underlying quantum mechanism responsible for the saturation. To this end we express OTOCs by coherent sums over contributions from different mean-field solutions and compute the dominant many body interference term amongst them. Our method further applies to the complementary semiclassical limit h->0 for fixed N, including quantum-chaotic single- and few-particle systems. PMID- 30296113 TI - Direct Measurement of Anharmonic Decay Channels of a Coherent Phonon. AB - We report channel-resolved measurements of the anharmonic coupling of the coherent A_{1g} phonon in photoexcited bismuth to pairs of high wave vector acoustic phonons. The decay of a coherent phonon can be understood as a parametric resonance process whereby the atomic displacement periodically modulates the frequency of a broad continuum of modes. This coupling drives temporal oscillations in the phonon mean-square displacements at the A_{1g} frequency that are observed across the Brillouin zone by femtosecond x-ray diffuse scattering. We extract anharmonic coupling constants between the A_{1g} and several representative decay channels that are within an order of magnitude of density functional perturbation theory calculations. PMID- 30296115 TI - Quantum Spin Dynamics in a Normal Bose Gas with Spin-Orbit Coupling. AB - In this Letter, we investigate spin dynamics of a two-component Bose gas with spin-orbit coupling realized in cold atom experiments. We derive coupled hydrodynamic equations for number and spin densities as well as their associated currents. Specializing to the quasi-one-dimensional situation, we obtain analytic solutions of the spin helix structure and its dynamics in both adiabatic and diabatic regimes. In the adiabatic regime, the transverse spin decays parabolically in the short-time limit and exponentially in the long-time limit, depending on initial polarization. In contrast, in the diabatic regime, transverse spin density and current oscillate in a way similar to the charge current oscillation in an undamped LC circuit. The effects of Rabi coupling on the short-time spin dynamics is also discussed. Finally, using realistic experimental parameters for ^{87}Rb, we show that the timescales for spin dynamics is of the order of milliseconds to a few seconds and can be observed experimentally. PMID- 30296116 TI - Tumbling of Inertial Fibers in Turbulence. AB - Anisotropic particles play a major role in many environmental and industrial turbulent flows. The modeling of their rotation dynamics is a fundamental challenge which has some important consequences in industrial processes, such as in the paper making industry. This study investigates the rotation rate of neutrally buoyant fibers longer than the Kolmogorov length eta_{K}. We show that the fiber inertia is at the origin of a decrease of the rotation rate. We propose a model which describes this phenomenon. We introduce also a new Stokes number which defines the limit of validity of the classical slender body approximation. PMID- 30296117 TI - Anomalous Phonon Lifetime Shortening in Paramagnetic CrN Caused by Spin-Lattice Coupling: A Combined Spin and Ab Initio Molecular Dynamics Study. AB - We study the mutual coupling of spin fluctuations and lattice vibrations in paramagnetic CrN by combining atomistic spin dynamics and ab initio molecular dynamics. The two degrees of freedom are dynamically coupled, leading to nonadiabatic effects. Those effects suppress the phonon lifetimes at low temperature compared to an adiabatic approach. The dynamic coupling identified here provides an explanation for the experimentally observed unexpected temperature dependence of the thermal conductivity of magnetic semiconductors above the magnetic ordering temperature. PMID- 30296118 TI - 21-cm Fluctuations from Charged Dark Matter. AB - The epoch of the formation of the first stars, known as the cosmic dawn, has emerged as a new arena in the search for dark matter. In particular, the first claimed 21-cm detection exhibits a deeper global absorption feature than expected, which could be caused by a low baryonic temperature, and has been interpreted as a sign for electromagnetic interactions between baryons and dark matter. This hypothesis has a striking prediction: large temperature anisotropies sourced by the velocity-dependent cooling of the baryons. However, in order to remain consistent with the rest of cosmological observations, only part of the dark matter is allowed to be charged and thus interactive. Here we compute, for the first time, the 21-cm fluctuations caused by a charged subcomponent of the dark matter, including both the pre- and postrecombination evolution of all fluids. We find that, for the same parameters that can explain the anomalous 21 cm absorption signal, any percent-level fraction of charged dark matter would source novel 21-cm fluctuations with a unique acoustic spectrum, and with an amplitude above any other known effects. These fluctuations are uncorrelated with the usual adiabatic anisotropies, and would be observable at high significance with interferometers such as the Low-Frequency Array and the Hydrogen Epoch of Reionization Array, thus providing a novel probe of dark matter at cosmic dawn. PMID- 30296120 TI - Cycling Tames Power Fluctuations near Optimum Efficiency. AB - According to the laws of thermodynamics, no heat engine can beat the efficiency of a Carnot cycle. This efficiency traditionally comes with vanishing power output and practical designs, optimized for power, generally achieve far less. Recently, various strategies to obtain Carnot's efficiency at large power were proposed. However, a thermodynamic uncertainty relation implies that steady-state heat engines can operate in this regime only at the cost of large fluctuations that render them immensely unreliable. Here, we demonstrate that this unfortunate trade-off can be overcome by designs operating cyclically under quasistatic conditions. The experimentally relevant yet exactly solvable model of an overdamped Brownian heat engine is used to illustrate the formal result. Our study highlights that work in cyclic heat engines and that in quasistatic ones are different stochastic processes. PMID- 30296119 TI - Thermal Critical Points and Quantum Critical End Point in the Frustrated Bilayer Heisenberg Antiferromagnet. AB - We consider the finite-temperature phase diagram of the S=1/2 frustrated Heisenberg bilayer. Although this two-dimensional system may show magnetic order only at zero temperature, we demonstrate the presence of a line of finite temperature critical points related to the line of first-order transitions between the dimer-singlet and -triplet regimes. We show by high-precision quantum Monte Carlo simulations, which are sign-free in the fully frustrated limit, that this critical point is in the Ising universality class. At zero temperature, the continuous transition between the ordered bilayer and the dimer-singlet state terminates on the first-order line, giving a quantum critical end point, and we use tensor-network calculations to follow the first-order discontinuities in its vicinity. PMID- 30296121 TI - Complexity Growth Rate in Lovelock Gravity. AB - Using the complexity=action framework, we compute the late time growth of complexity for charged black holes in Lovelock gravity. Our calculation is facilitated by the fact that the null boundaries of the Wheeler-DeWitt patch do not contribute at late times and essential contributions coming from the joints are now understood. The late time growth rate reduces to a difference of internal energies associated with the inner and outer horizons, and in the limit where the mass is much larger than the charge, we reproduce the celebrated result of 2M/pi with corrections proportional to the highest Lovelock coupling in even (boundary) dimensions. We find in some cases a minimum mass below which complexity remains effectively constant, even if the black hole contains a nondegenerate horizon. PMID- 30296122 TI - Invisible Neutrino Decay Could Resolve IceCube's Track and Cascade Tension. AB - The IceCube Neutrino Observatory detects high energy astrophysical neutrinos in two event topologies: tracks and cascades. Since the flavor composition of each event topology differs, tracks and cascades can be used to test the neutrino properties and the mechanisms behind the neutrino production in astrophysical sources. Assuming a conventional model for the neutrino production, the IceCube data sets related to the two channels are in >3sigma tension with each other. Invisible neutrino decay with lifetime tau/m=10^{2} s/eV solves this tension. Noticeably, it leads to an improvement over the standard nondecay scenario of more than 3sigma while remaining consistent with all other multimessenger observations. In addition, our invisible neutrino decay model predicts a reduction of 59% in the number of observed nu_{tau} events which is consistent with the current observational deficit. PMID- 30296123 TI - Quantum Nonlinear Optics in Atomically Thin Materials. AB - We show that a nonlinear optical response associated with a resonant, atomically thin material can be dramatically enhanced by placing it in front of a partially reflecting mirror, rendering otherwise weakly nonlinear systems suitable for experiments and applications involving quantum nonlinear optics. Our approach exploits the nonlinear response of long-lived polariton resonances that arise at particular distances between the material and the mirror. The scheme is entirely based on free-space optics, eliminating the need for cavities or complex nanophotonic structures. We analyze a specific implementation based on exciton polariton resonances in two-dimensional semiconductors and discuss the role of imperfections and loss. PMID- 30296124 TI - Stability of Periodically Driven Topological Phases against Disorder. AB - In recent experiments, time-dependent periodic fields are used to create exotic topological phases of matter with potential applications ranging from quantum transport to quantum computing. These nonequilibrium states, at high driving frequencies, exhibit the quintessential robustness against local disorder similar to equilibrium topological phases. However, proving the existence of such topological phases in a general setting is an open problem. We propose a universal effective theory that leverages on modern free probability theory and ideas in random matrices to analytically predict the existence of the topological phase for finite driving frequencies and across a range of disorder. We find that, depending on the strength of disorder, such systems may be topological or trivial and that there is a transition between the two. In particular, the theory predicts the critical point for the transition between the two phases and provides the critical exponents. We corroborate our results by comparing them to exact diagonalizations for driven-disordered 1D Kitaev chain and 2D Bernevig Hughes-Zhang models and find excellent agreement. This Letter may guide the experimental efforts for exploring topological phases. PMID- 30296125 TI - Mirage Andreev Spectra Generated by Mesoscopic Leads in Nanowire Quantum Dots. AB - We study transport mediated by Andreev bound states formed in InSb nanowire quantum dots. Two kinds of superconducting source and drain contacts are used: epitaxial Al/InSb devices exhibit a doubling of tunneling resonances, while, in NbTiN/InSb devices, Andreev spectra of the dot appear to be replicated multiple times at increasing source-drain bias voltages. In both devices, a mirage of a crowded spectrum is created. To describe the observations a model is developed that combines the effects of a soft induced gap and of additional Andreev bound states both in the quantum dot and in the finite regions of the nanowire adjacent to the quantum dot. Understanding of Andreev spectroscopy is important for the correct interpretation of Majorana experiments done on the same structures.

AB - This Letter reports on the experimental observation of a topologically protected edge state and exceptional point in an open and non-Hermitian (lossy) acoustic system. Although the theoretical underpinning is generic to wave physics, the simulations and experiments are performed for an acoustic system. It has nontrivial topological properties that can be characterized by the Chern number provided that a synthetic dimension is introduced. Unidirectional reflectionless propagation, a hallmark of exceptional points, is unambiguously observed in both simulations and experiments. PMID- 30296130 TI - Energy Storage via Topological Spin Textures. AB - We formulate an energy-storage concept based on the free energy associated with metastable magnetic configurations. Despite the active magnetic region of the battery being electrically insulating, it can sustain effective hydrodynamics of spin textures, whose conservation law is governed by topology. To illustrate the key physics and potential functionality, we focus here on the simplest quasi-one dimensional case of planar winding of the magnetic order parameter. The energy is stored in the metastable winding number, which can be injected electrically by an appropriately tailored spin torque. Because of the nonvolatility and the endurance of magnetic systems, the injected energy can be stored essentially indefinitely, with the topological charge cycles that do not degrade over time. PMID- 30296129 TI - Binary Two-Dimensional Honeycomb Lattice with Strong Spin-Orbit Coupling and Electron-Hole Asymmetry. AB - Two-dimensional (2D) materials consisting of heavy atoms with particular arrangements may host exotic quantum properties. Here, we report a unique 2D semiconducting binary compound, a Sn_{2}Bi atomic layer on Si(111), in which hexagons are formed by bonding Bi with a triangular network of Sn. Because of the unique honeycomb configuration, the heavy elements, and the energy-dependent hybridization between Sn and Bi, 2D Sn_{2}Bi not only shows strong spin-orbit coupling effects but also exhibits high electron-hole asymmetry: Nearly free hole bands and dispersionless flat electron bands coexist in the same system. By tuning the Fermi level, it is possible to preserve both nearly free and strongly localized charge carriers in the same 2D material, which provides an ideal platform for the studies of strongly correlated phenomena and possible applications in nanodevices. PMID- 30296131 TI - Optimal Work Extraction and Thermodynamics of Quantum Measurements and Correlations. AB - We analyze the role of indirect quantum measurements in work extraction from quantum systems in nonequilibrium states. In particular, we focus on the work that can be obtained by exploiting the correlations shared between the system of interest and an additional ancilla, where measurement backaction introduces a nontrivial thermodynamic tradeoff. We present optimal state-dependent protocols for extracting work from both classical and quantum correlations, the latter being measured by discord. Our quantitative analysis establishes that, while the work content of classical correlations can be fully extracted by performing local operations on the system of interest, accessing work related to quantum discord requires a specific driving protocol that includes interaction between system and ancilla. PMID- 30296132 TI - Strongly Coupled Anisotropic Gauge Theories and Holography. AB - We initiate a nonperturbative study of anisotropic, nonconformal, and confining gauge theories that are holographically realized in gravity by generic Einstein axion-dilaton systems. In the vacuum, our solutions describe renormalization group flows from a conformal field theory in the UV to generic scaling solutions in the IR with generic hyperscaling violation and dynamical exponents theta and z. We formulate a generalization of the holographic c theorem to the anisotropic case. At finite temperature, we discover that the anisotropic deformation reduces the confinement-deconfinement phase transition temperature suggesting a possible alternative explanation of inverse magnetic catalysis solely based on anisotropy. We also study transport and diffusion properties in anisotropic theories and observe, in particular, that the butterfly velocity that characterizes both diffusion and growth of chaos transverse to the anisotropic direction saturates a constant value in the IR which can exceed the bound given by the conformal value. PMID- 30296136 TI - Role of Radial Charges on the Angular Momentum of Electromagnetic Fields: Spin 3/2 Light. AB - Electromagnetic fields carry a linear and an angular momentum, the first being responsible for the existence of the radiation pressure and the second for the transfer of torque from electromagnetic radiation to matter. The angular momentum is considered to have two components, one due to the polarization state of the field, usually called spin angular momentum (SAM), and one due to the existence of topological azimuthal charges in the field phase profile, which leads to the orbital angular momentum (OAM). These two contributions to the total angular momentum of an electromagnetic field appear, however, to not be independent of each other, something which is described as spin-orbit coupling. Understanding the physics of this coupling has kept scientists busy for decades. Very recently it has been shown that electromagnetic fields necessarily carry also invariant radial charges that, as discussed in this Letter, play a key role in the angular momentum. Here we show that the total angular momentum consists in fact of three components: one component only dependent on the spin of the field, another dependent on the azimuthal charges carried by the field, and a third component dependent on the spin and the radial charges contained in the field. By properly controlling the number and coupling among these radial charges it is possible to design electromagnetic fields with a desired total angular momentum. Remarkably, we also discover fields with no orbital angular momentum and a spin angular momentum typical of spin-3/2 objects, irrespective of the fact that photons are spin-1 particles.

AB - We report a transition from asynchronous to oscillatory behavior in balanced inhibitory networks for class I and II neurons with instantaneous synapses. Collective oscillations emerge for sufficiently connected networks. Their origin is understood in terms of a recently developed mean-field model, whose stable solution is a focus. Microscopic irregular firings, due to balance, trigger sustained oscillations by exciting the relaxation dynamics towards the macroscopic focus. The same mechanism induces in balanced excitatory-inhibitory networks quasiperiodic collective oscillations. PMID- 30296137 TI - Roura Replies. PMID- 30296135 TI - Nonreciprocity Realized with Quantum Nonlinearity. AB - Nonreciprocal devices are a key element for signal routing and noise isolation. Rapid development of quantum technologies has boosted the demand for a new generation of miniaturized and low-loss nonreciprocal components. Here, we use a pair of tunable superconducting artificial atoms in a 1D waveguide to experimentally realize a minimal passive nonreciprocal device. Taking advantage of the quantum nonlinear behavior of artificial atoms, we achieve nonreciprocal transmission through the waveguide in a wide range of powers. Our results are consistent with theoretical modeling showing that nonreciprocity is associated with the population of the two-qubit nonlocal entangled quasidark state, which responds asymmetrically to incident fields from opposing directions. Our experiment highlights the role of quantum correlations in enabling nonreciprocal behavior and opens a path to building passive quantum nonreciprocal devices without magnetic fields.

AB - Although discovered many decades ago, superconductivity in doped SrTiO_{3} remains a topic of intense research. Recent experiments revealed that, upon increasing the carrier concentration, multiple bands cross the Fermi level, signaling the onset of Lifshitz transitions. Interestingly, T_{c} was observed to be suppressed across the Lifshitz transition of oxygen-deficient SrTiO_{3}; a similar behavior was also observed in gated LaAlO_{3}/SrTiO_{3} interfaces. Such a behavior is difficult to explain in the clean theory of two-band superconductivity, as the additional electronic states provided by the second band should enhance T_{c}. Here, we show that this unexpected behavior can be explained by the strong pair-breaking effect promoted by disorder, which takes place if the interband pairing interaction is subleading and repulsive. A consequence of this scenario is that, upon moving away from the Lifshitz transition, the two-band superconducting state changes from opposite-sign gaps to same-sign gaps.

PMID- 30296141 TI - Fragile Topology and Wannier Obstructions. AB - Topological phases, such as Chern insulators, are defined in terms of additive indices that are stable against the addition of trivial degrees of freedom. Such topology presents an obstruction to any Wannier representation, namely, the representation of the electronic states in terms of symmetric, exponentially localized Wannier functions. Here, we address the converse question: Do obstructions to Wannier representation imply stable band topology? We answer this in the negative, pointing out that some bands can also display a distinct type of "fragile topology." Bands with fragile topology do not admit any Wannier representation by themselves, but such a representation becomes possible once certain additional trivial degrees of freedom are supplied. We construct a physical model of fragile topology on the honeycomb lattice that also helps resolve a recent puzzle in band theory. This model provides a counterexample to the assumption that splitting of an "elementary band representation" introduced in [B. Bradlyn et al., Topological quantum chemistry, Nature (London) 547, 298 (2017)] leads to bands that are individually topological. Instead, half of the split bands of our model realize a trivial band with exponentially localized symmetric Wannier functions, whereas the second half possess fragile topology. Our work highlights an important and previously overlooked connection between band structure and Wannier functions, and is expected to have far-reaching consequences given the central role played by Wannier functions in the modeling of real materials. PMID- 30296142 TI - Periodic Motion of Sedimenting Flexible Knots. AB - We study the dynamics of knotted deformable closed chains sedimenting in a viscous fluid. We show experimentally that trefoil and other torus knots often attain a remarkably regular horizontal toroidal structure while sedimenting, with a number of intertwined loops, oscillating periodically around each other. We then recover this motion numerically and find out that it is accompanied by a very slow rotation around the vertical symmetry axis. We analyze the dependence of the characteristic timescales on the chain flexibility and aspect ratio. It is observed in the experiments that this oscillating mode of the dynamics can spontaneously form even when starting from a qualitatively different initial configuration. In numerical simulations, the oscillating modes are usually present as transients or final stages of the evolution, depending on chain aspect ratio and flexibility, and the number of loops. PMID- 30296143 TI - High-Fidelity Control and Entanglement of Rydberg-Atom Qubits. AB - Individual neutral atoms excited to Rydberg states are a promising platform for quantum simulation and quantum information processing. However, experimental progress to date has been limited by short coherence times and relatively low gate fidelities associated with such Rydberg excitations. We report progress towards high-fidelity quantum control of Rydberg-atom qubits. Enabled by a reduction in laser phase noise, our approach yields a significant improvement in coherence properties of individual qubits. We further show that this high fidelity control extends to the multi-particle case by preparing a two-atom entangled state with a fidelity exceeding 0.97(3), and extending its lifetime with a two-atom dynamical decoupling protocol. These advances open up new prospects for scalable quantum simulation and quantum computation with neutral atoms. PMID- 30296144 TI - Strong and Tunable Spin-Lifetime Anisotropy in Dual-Gated Bilayer Graphene. AB - We report the discovery of a strong and tunable spin-lifetime anisotropy with excellent out-of-plane spin lifetimes up to 7.8 ns at 100 K in dual-gated bilayer graphene. Remarkably, this realizes the manipulation of spins in graphene by electrically controlled spin-orbit fields, which is unexpected due to graphene's weak intrinsic spin-orbit coupling (~12 MUeV). We utilize both the in-plane magnetic field Hanle precession and oblique Hanle precession measurements to directly compare the lifetimes of out-of-plane vs in-plane spins. We find that near the charge neutrality point, the application of a perpendicular electric field opens a band gap and generates an out-of-plane spin-orbit field that stabilizes out-of-plane spins against spin relaxation, leading to a large spin lifetime anisotropy (defined as the ratio between out-of-plane and in-plane spin lifetime) up to ~12 at 100 K. This intriguing behavior occurs because of the unique spin-valley coupled band structure of bilayer graphene. Our results demonstrate the potential for highly tunable spintronic devices based on dual gated 2D materials. PMID- 30296145 TI - Interaction-Driven Giant Orbital Magnetic Moments in Carbon Nanotubes. AB - Carbon nanotubes continue to be model systems for studies of confinement and interactions. This is particularly true in the case of so-called "ultraclean" carbon nanotube devices offering the study of quantum dots with extremely low disorder. The quality of such systems, however, has increasingly revealed glaring discrepancies between experiment and theory. Here, we address the outstanding anomaly of exceptionally large orbital magnetic moments in carbon nanotube quantum dots. We perform low temperature magnetotransport measurements of the orbital magnetic moment and find it is up to 7 times larger than expected from the conventional semiclassical model. Moreover, the magnitude of the magnetic moment monotonically drops with the addition of each electron to the quantum dot directly contradicting the widely accepted shell filling picture of single particle levels. We carry out quasiparticle calculations, both from first principles and within the effective-mass approximation, and find the giant magnetic moments can only be captured by considering a self-energy correction to the electronic band structure due to electron-electron interactions.

At 75 K and the charge neutrality point (CNP), we observe a strong anisotropy of tau_{?}/tau_{?}=8+/-2. This value is comparable to graphene-transition-metal-dichalcogenide heterostructures, whereas our high quality BLG provides with tau_{?} up to 9 ns, a spin lifetime more than 2 orders of magnitude larger. The anisotropy decreases to 3.5+/-1 at a carrier density of n=6*10^{11} cm^{-2}. Temperature-dependent measurements show above 75 K a decrease of tau_{?}/tau_{?} with increasing temperature, reaching the isotropic case close to room temperature. We explain our findings with electric-field induced spin-valley coupling arising from the small intrinsic spin-orbit fields in BLG of 12 MUeV at the CNP.

AB - We present a theoretical investigation of the origin of Raman-like and fluorescencelike (FL) features of resonant inelastic x-ray scattering (RIXS) spectra. Using a combination of local-density approximation+dynamical mean-field theory and a configuration interaction solver for Anderson impurity model, we calculate the L-edge RIXS and x-ray absorption spectra of high-valence transition metal oxides LaCuO_{3} and NaCuO_{2}. We analyze in detail the behavior of the FL feature and show how it is connected to the details of electronic and crystal structure. On the studied compounds we demonstrate how material details determine whether the electron-hole continuum can be excited in the L-edge RIXS process.

AB - We show that in gapped bilayer graphene, quasiparticle tunneling and the corresponding Berry phase can be controlled such that they exhibit features of single-layer graphene such as Klein tunneling. The Berry phase is detected by a high-quality Fabry-Perot interferometer based on bilayer graphene. By raising the Fermi energy of the charge carriers, we find that the Berry phase can be continuously tuned from 2pi down to 0.68pi in gapped bilayer graphene, in contrast to the constant Berry phase of 2pi in pristine bilayer graphene. Particularly, we observe a Berry phase of pi, the standard value for single-layer graphene. As the Berry phase decreases, the corresponding transmission probability of charge carriers at normal incidence clearly demonstrates a transition from anti-Klein tunneling to nearly perfect Klein tunneling. PMID- 30296150 TI - Anomalous Breaking of Scale Invariance in a Two-Dimensional Fermi Gas. AB - The frequency of the breathing mode of a two-dimensional Fermi gas with zero range interactions in a harmonic confinement is fixed by the scale invariance of the Hamiltonian. Scale invariance is broken in the quantized theory by introducing the two-dimensional scattering length as a regulator. This is an example of a quantum anomaly in the field of ultracold atoms and leads to a shift of the frequency of the collective breathing mode of the cloud. In this work, we study this anomalous frequency shift for a two-component Fermi gas in the strongly interacting regime. We measure significant upwards shifts away from the scale-invariant result that show a strong interaction dependence. This observation implies that scale invariance is broken anomalously in the strongly interacting two-dimensional Fermi gas. PMID- 30296149 TI - Quantum Anomaly and 2D-3D Crossover in Strongly Interacting Fermi Gases. AB - We present an experimental investigation of collective oscillations in harmonically trapped Fermi gases through the crossover from two to three dimensions. Specifically, we measure the frequency of the radial monopole oscillation or breathing mode in highly oblate gases with tunable interactions. The breathing mode frequency is set by the adiabatic compressibility and probes the thermodynamic equation of state. In 2D, a dynamical scaling symmetry for atoms interacting via a delta potential predicts the breathing mode to occur at exactly twice the harmonic confinement frequency. However, a renormalized quantum treatment introduces a new length scale which breaks this classical scale invariance resulting in a so-called quantum anomaly. Our measurements deep in the 2D regime lie above the scale-invariant prediction for a range of interaction strengths providing evidence for the quantum anomaly and signifying the breakdown of an elementary delta-potential model of atomic interactions. By varying the atom number we can tune the chemical potential and see the breathing mode frequency evolve smoothly between the 2D to 3D thermodynamic limits. PMID- 30296151 TI - Deterministic Free-Space Source of Single Photons Using Rydberg Atoms. AB - We propose an efficient free-space scheme to create single photons in a well defined spatiotemporal mode. To that end, we first prepare a single source atom in an excited Rydberg state. The source atom interacts with a large ensemble of ground-state atoms via a laser-mediated dipole-dipole exchange interaction. Using an adiabatic passage with a chirped laser pulse, we produce a spatially extended spin wave of a single Rydberg excitation in the ensemble, accompanied by the transition of the source atom to another Rydberg state. The collective atomic excitation can then be converted to a propagating optical photon via a coherent coupling field. In contrast to previous approaches, our single-photon source does not rely on the strong coupling of a single emitter to a resonant cavity, nor does it require the heralding of collective excitation or complete Rydberg blockade of multiple excitations in the atomic ensemble. PMID- 30296152 TI - Keldysh-Rutherford Model for the Attoclock. AB - We demonstrate a clear similarity between attoclock offset angles and Rutherford scattering angles taking the Keldysh tunneling width as the impact parameter and the vector potential of the driving pulse as the asymptotic velocity. This simple model is tested against the solution of the time-dependent Schrodinger equation using hydrogenic and screened (Yukawa) potentials of equal binding energy. We observe a smooth transition from a hydrogenic to "hard-zero" intensity dependence of the offset angle with variation of the Yukawa screening parameter. Additionally, we make a comparison with the attoclock offset angles for various noble gases obtained with the classical-trajectory Monte Carlo method. In all cases we find a close correspondence between the model predictions and numerical calculations. This suggests a largely Coulombic origin of the attoclock offset angle and casts further doubt on its interpretation in terms of a finite tunneling time. PMID- 30296153 TI - Microscopic Origin of Frictional Rheology in Dense Suspensions: Correlations in Force Space. AB - We develop a statistical framework for the rheology of dense, non-Brownian suspensions, based on correlations in a space representing forces, which is dual to position space. Working with the ensemble of steady state configurations obtained from simulations of suspensions in two dimensions, we find that the anisotropy of the pair correlation function in force space changes with confining shear stress (sigma_{xy}) and packing fraction (phi). Using these microscopic correlations, we build a statistical theory for the macroscopic friction coefficient: the anisotropy of the stress tensor, MU=sigma_{xy}/P. We find that MU decreases (i) as phi is increased and (ii) as sigma_{xy} is increased. Using a new constitutive relation between MU and viscosity for dense suspensions that generalizes the rate-independent one, we show that our theory predicts a discontinuous shear thickening flow diagram that is in good agreement with numerical simulations, and the qualitative features of MU that lead to the generic flow diagram of a discontinuous shear thickening fluid observed in experiments. PMID- 30296154 TI - Constraint-Based Approach to Granular Dispersion Rheology. AB - We present a phenomenological model for granular suspension rheology in which particle interactions enter as constraints to relative particle motion. By considering constraints that are formed and released by stress respectively, we derive a range of experimental flow curves in a single treatment and predict singularities in viscosity and yield stress consistent with literature data. Fundamentally, we offer a generic description of suspension flow that is independent of bespoke microphysics. PMID- 30296155 TI - Anomalous Hall Effect in 2D Dirac Materials. AB - We present a unified theory of charge carrier transport in 2D Dirac systems with broken mirror inversion and time-reversal symmetries (e.g., as realized in ferromagnetic graphene). We find that the entanglement between spin and pseudospin SU(2) degrees of freedom stemming from spin-orbit effects leads to a distinctive gate voltage dependence (change of sign) of the anomalous Hall conductivity approaching the topological gap, which remains robust against impurity scattering and thus is a smoking gun for magnetized 2D Dirac fermions. Furthermore, we unveil a robust skew scattering mechanism, modulated by the spin texture of the energy bands, which causes a net spin accumulation at the sample boundaries even for spin-transparent disorder. The newly unveiled extrinsic spin Hall effect is readily tunable by a gate voltage and opens novel opportunities for the control of spin currents in 2D ferromagnetic materials. PMID- 30296156 TI - Quantum Spin Hall Effect and Spin Bott Index in a Quasicrystal Lattice. AB - Despite the rapid progress in the field of the quantum spin Hall (QSH) effect, most of the QSH systems studied up to now are based on crystalline materials. Here we propose that the QSH effect can be realized in quasicrystal lattices (QLs). We show that the electronic topology of aperiodic and amorphous insulators can be characterized by a spin Bott index B_{s}. The nontrivial QSH state in a QL is identified by a nonzero spin Bott index B_{s}=1, associated with robust edge states and quantized conductance. We also map out a topological phase diagram in which the QSH state lies in between a normal insulator and a weak metal phase due to the unique wave functions of QLs. Our findings not only provide a better understanding of electronic properties of quasicrystals but also extend the search of the QSH phase to aperiodic and amorphous materials that are experimentally feasible. PMID- 30296158 TI - Painting Nonclassical States of Spin or Motion with Shaped Single Photons. AB - We propose a robust scheme for generating macroscopic superposition states of spin or motion with the aid of a single photon. Shaping the wave packet of the photon enables high-fidelity preparation of nonclassical states of matter even in the presence of photon loss. Success is heralded by photodetection, enabling the scheme to be implemented with a weak coherent field. We analyze applications to preparing Schrodinger cat states of a collective atomic spin or of a mechanical oscillator coupled to an optical resonator. The method generalizes to preparing arbitrary superpositions of coherent states, enabling full quantum control. We illustrate this versatility by showing how to prepare Dicke or Fock states, as well as superpositions in the Dicke or Fock basis. PMID- 30296157 TI - Spectral Evidence for Emergent Order in Ba_{1-x}Na_{x}Fe_{2}As_{2}. AB - We report an angle-resolved photoemission spectroscopy study of the iron-based superconductor family, Ba_{1-x}Na_{x}Fe_{2}As_{2}. This system harbors the recently discovered double-Q magnetic order appearing in a reentrant C_{4} phase deep within the underdoped regime of the phase diagram that is otherwise dominated by the coupled nematic phase and collinear antiferromagnetic order. From a detailed temperature-dependence study, we identify the electronic response to the nematic phase in an orbital-dependent band shift that strictly follows the rotational symmetry of the lattice and disappears when the system restores C_{4} symmetry in the low temperature phase. In addition, we report the observation of a distinct electronic reconstruction that cannot be explained by the known electronic orders in the system. PMID- 30296160 TI - Discontinuous Phase Transitions in Nonlocal Schloegl Models for Autocatalysis: Loss and Reemergence of a Nonequilibrium Gibbs Phase Rule. AB - We consider Schloegl models (or contact processes) where particles on a square grid annihilate at a rate p and are created at a rate of k_{n}=n(n-1)/[N(N-1)] at empty sites with n particles in a neighborhood Omega_{N} of size N. Simulation reveals a discontinuous transition between populated and vacuum states, but equistable p=p_{eq} determined by the stationarity of planar interfaces between these states depends on the interface orientation and on Omega_{N}. The behavior for large Omega_{N} follows from continuum equations. These also depend on the interface orientation and on Omega_{N} shape, but a unique p_{eq}=0.211 376 320 4 emerges imposing a Gibbs phase rule. PMID- 30296159 TI - Pareto Optimality in Multilayer Network Growth. AB - We model the formation of multilayer transportation networks as a multiobjective optimization process, where service providers compete for passengers, and the creation of routes is determined by a multiobjective cost function encoding a trade-off between efficiency and competition. The resulting model reproduces well real-world systems as diverse as airplane, train, and bus networks, thus suggesting that such systems are indeed compatible with the proposed local optimization mechanisms. In the specific case of airline transportation systems, we show that the networks of routes operated by each company are placed very close to the theoretical Pareto front in the efficiency-competition plane, and that most of the largest carriers of a continent belong to the corresponding Pareto front. Our results shed light on the fundamental role played by multiobjective optimization principles in shaping the structure of large-scale multilayer transportation systems, and provide novel insights to service providers on the strategies for the smart selection of novel routes. PMID- 30296161 TI - Fractional Excitonic Insulator. AB - We argue that a correlated fluid of electrons and holes can exhibit a fractional quantum Hall effect at zero magnetic field analogous to the Laughlin state at filling 1/m. We introduce a variant of the Laughlin wave function for electrons and holes and show that for m=1 it is the exact ground state of a free fermion model that describes p_{x}+ip_{y} excitonic pairing. For m>1 we develop a simple composite fermion mean field theory, and we present evidence that our wave function correctly describes this phase. We derive an interacting Hamiltonian for which our wave function is the exact ground state, and we present physical arguments that the m=3 state can be realized in a system in which energy bands with angular momentum that differ by 3 cross at the Fermi energy. This leads to a gapless state with (p_{x}+ip_{y})^{3} excitonic pairing, which we argue is conducive to forming the fractional excitonic insulator in the presence of interactions. Prospects for numerics on model systems and band structure engineering to realize this phase in real materials are discussed. PMID- 30296162 TI - Network Model of the Disordered Phase in Symmetric Diblock Copolymer Melts. AB - We present a model for the order-disorder transition of symmetric A-B diblock copolymer melts in which the disordered phase is treated as a bicontinuous network, and in which self-consistent field predictions of properties of an analogous ordered network are used to estimate some properties. Such a model is shown to accurately predict the latent heat of this transition. The dependence of the location of the transition upon the invariant degree of polymerization N[over -] is shown to be consistent with a simple hypothesis that the disordered bicontinuous structure is stabilized relative to an analogous ordered network by a nearly constant entropy per network junction. PMID- 30296163 TI - Dual Conformal Structure Beyond the Planar Limit. AB - The planar scattering amplitudes of N=4 super-Yang-Mills theory display symmetries and structures which underlie their relatively simple analytic properties such as having only logarithmic singularities and no poles at infinity. Recent work shows in various nontrivial examples that the simple analytic properties of the planar sector survive into the nonplanar sector, but this has yet to be understood from underlying symmetries. Here, we explicitly show that for an infinite class of nonplanar integrals that covers all subleading color contributions to the two-loop four- and five-point amplitudes of N=4 super Yang-Mills theory, symmetries analogous to dual conformal invariance exist. A natural conjecture is that this continues to all amplitudes of the theory at any loop order. PMID- 30296164 TI - Effects of Polarization on Particle-Laden Flows. AB - Simulations of particle-laden flow with dielectric particles are carried out with varying levels of electrical charging and particle polarization. Simulation results reveal three distinct flow regions. For low particle charge and polarizability, flow is nearly symmetric and nonmeandering. For strong charging and polarization, particles form a continuous and tightly clustered sheet close to one of the walls. Between these extremes, particles form localized particle rich regions, around which the gas executes a meandering flow. These results indicate that polarization can lead to qualitative changes in the characteristics of particle-laden flows subject to tribocharging. PMID- 30296165 TI - Hyperbolic Dispersion Arising from Anisotropic Excitons in Two-Dimensional Perovskites. AB - Excitations of free electrons and optical phonons are known to permit access to the negative real part of relative permittivities (epsilon^{'}<0) that yield strong light-matter interactions. However, negative epsilon^{'} arising from excitons has been much less explored. Via development of a dielectric-coating based technique described herein, we report fundamental optical properties of two dimensional hybrid perovskites (2DHPs), composed of alternating layers of inorganic and organic sublattices. Low members of 2DHPs (N=1 and N=2) exhibit negative epsilon^{'} stemming from the large exciton binding energy and sizable oscillator strength. Furthermore, hyperbolic dispersion (i.e., epsilon^{'} changes sign with directions) occurs in the visible range, which has been previously achieved only with artificial metamaterials. Such naturally occurring, exotic dispersion stems from the extremely anisotropic excitonic behaviors of 2DHPs, and can intrinsically support a large photonic density of states. We suggest that several other van der Waals solids may exhibit similar behaviors arising from excitonic response. PMID- 30296166 TI - Molecular techniques reveal more secrets of fermented foods. AB - Fermented foods were likely to have been the first among all types of processed foods consumed by human beings. The role that fermented food plays is not only related to the development of civilizations and cultural relationships between countries but also related to the nutritional importance of its population. Of course, the early manufacturers of fermented foods didn't take into account the advantages of modern sciences, because enzymes and microorganisms were discovered just 150-200 years ago. For that reason, we can conclude why the ancient fermentation techniques were known to philosophers and alchemists, but not to biologists. It demonstrated that the fermentation mechanisms involved many secrets still undiscovered. Recently, applications of molecular techniques for analyzing and study the fermented foods have been explored. In this review, we provide answers with a critical vision to many questions for understanding the role of molecular techniques to discover the secrets of fermented foods such as how to evaluate the traditional fermented foods? Why using molecular techniques to study the fermented foods not else? Is the future will carry to us a boom in molecular technologies contribute to the detection of more secrets of the fermented food? PMID- 30296167 TI - Changes of ruminal pH, rumination activity and feeding behaviour during early lactation as affected by different energy and fibre concentrations of roughage in pluriparous dairy cows. AB - The aim of this study was to assess differences of ruminal pH and rumination activity between the prepartal and postpartal period of cows and to investigate changes of feeding behaviour and ruminal fermentation depending on postpartal rations with slight differences in roughage energy and fibre concentration. Therefore, 11 rumen-cannulated German Holstein cows were used from 3 weeks antepartum until 16 weeks postpartum. During the dry period, all cows received the same diet. After calving cows were assigned to two groups receiving partial mixed rations with different energy concentrations (6.1 MJ NEL/kg DM [moderate], with 18% straw on dry matter [DM] basis, group MR) or 6.5 MJ NEL/kg DM [high], with 6% straw on DM basis, group HR). In both groups, concentrates were supplied on average at 45% of total DM intake. Circadian measurements of ruminal pH, ruminal temperature and rumination activity were conducted weekly during the transition period and bi-weekly after week 4 postpartum. Throughout the postpartal period, feed intake behaviour was measured, and twice during the experiment, rumen fluid composition and net-acid-base excretion in urine were determined. Mean ruminal pH, feeding behaviour, rumination activity and rumen fluid composition did not differ between the groups, whereas group HR exhibited higher diurnal variations of pH and had a lower rumen temperature than group MR postpartum. However, these differences also occurred during the prepartal period when groups received equal rations. It was observed that ruminal pH values and the risk for subacute ruminal acidosis (SARA) were increased during postpartal period, whereby the circadian pH values showed high cow-individual variations. Overall, differences of energy and fibre concentrations in roughage did not affect the observed variables, whereby it should be noted that the number of cows was quite low in this study. Our results suggest that the ruminal pH characteristics are rather cow individual, indicating that cows presumably differ in their susceptibility to develop SARA. PMID- 30296168 TI - The temporal pattern of recovery in eccentric hamstring strength post-soccer specific fatigue. AB - Eccentric hamstring strength is an aetiological risk factor for soccer injury. The temporal pattern of recovery post-exercise is critical in injury management. 18 male professional soccer players completed baseline assessments of eccentric hamstring strength at isokinetic speeds of 60, 150 and 300 degrees . s-1. Post SAFT90 measures were repeated immediately, + 24 hrs, + 48 hrs and + 72 hrs. Main effects for recovery time and testing speed in average torque (AvT), peak torque (PT) and the corresponding angle (O) were supplemented by regression modelling to describe the temporal pattern of recovery. A main effect for isokinetic testing speed was observed in PT and AvT. A main effect for recovery time highlighted greater strength pre-exercise, with a quadratic pattern to temporal recovery highlighting minima achieved at between 40-48 hrs. Strength parameters are not fully recovered until 96 hrs post soccer specific fatigue, with implications for training design and injury management, particularly within fixture-congested periods. PMID- 30296169 TI - Stress reappraisal during a mathematics competition: testing effects on cardiovascular approach-oriented states and exploring the moderating role of gender. AB - BACKGROUND AND OBJECTIVES: Effects of reappraising stress arousal during an interpersonal competition were tested on physiological functioning and performance. Additionally, the moderating role of gender was explored. DESIGN AND METHOD: Participants (N = 279) were randomly assigned to a stress reappraisal, stress-is-debilitating, or a neutral control condition. Reappraisal materials educated participants about the adaptive benefits of stress, whereas stress-is debilitating materials instructed participants to avoid stress. Control materials did not mention stress. Participants then competed against a gender-matched confederate on a 10-minute math performance task while cardiovascular reactivity was assessed. Participants were instructed to complete math problems as quickly and accurately as they could and were informed that a winner and loser would be determined by the resulting math scores. RESULTS: Reappraising stress arousal led to more adaptive challenge-like cardiovascular responses, but no condition effects were observed on math performance. Exploratory analyses revealed that reappraisal instructions were effective for improving physiological functioning and facilitating performance for men, but women were unaffected by the manipulation. CONCLUSIONS: Reappraising stress arousal can improve physiological functioning during interpersonal competitions, but effects may be limited to men. Implications for future research are discussed. PMID- 30296170 TI - Spectral Ties: Hospital Hauntings Across the Line of Control. AB - In this article, we trace encounters between humans and phantasmic entities in hospitals in Indian-occupied and Pakistan-controlled Kashmir. In Pakistan, the presence of spectral beings (jinni) in hospitals is linked to state and sectarian violence, which precipitates ruptures between jinni and human worlds. Such breaches permit jinni to manifest in the medical present, where insecure actors harness them to ventriloquize unspoken anxieties. In Indian-occupied Kashmir, jinn-like, chronically mentally ill patients haunt psychiatric modernization projects. In embracing a jinneaological approach to medical crises, we theorize hospitals as multi-temporal and multi-dimensional spaces called "tesseracts," in which human-nonhuman encounters serve existential and political purposes. PMID- 30296172 TI - The use of estradiol metered-dose transdermal spray in clinical practice. AB - OBJECTIVE: The aim of this study was to evaluate the use of novel estradiol metered-dose transdermal spray (EMDTS) in the treatment of acute climacteric syndrome. METHODS: A multicenter open-label trial was conducted with a 24-week intervention. EMDTS 1.53 mg was given to symptomatic menopausal women. The Menopause Rating Scale (MRS) was used to assess the climacteric syndrome severity. The Friedman non-parametric test and a post-hoc test with Bonferroni correction were used for statistical evaluation. RESULTS: A total of 132 women were enrolled in 20 centers, of whom 123 (93.2%) completed the study. The average age of patients was 53.8 years (37-65 years). The study was discontinued by 6.8% of women. The patients were checked at the beginning of the study, and after 12 and 24 weeks. There was a statistically significant drop (p < 0.001) in MRS values both after 12 and 24 weeks of therapy. The average MRS values improved by 66.2% between the first and the third visits. The most significant improvement was manifested in patients with initial moderate climacteric syndrome (70.9%). CONCLUSION: This study confirms that application of EMDTS offers a novel treatment option for climacteric symptoms. PMID- 30296173 TI - Change in quality of life in relation to returning to work after acquired brain injury: a population-based register study. AB - PURPOSE: This study investigated changes in quality of life (QoL) in relation to return to work among patients with acquired brain injury (ABI). METHOD: The sample consisted of 1487 patients with ABI (63% men) aged 18-66 years (mean age 52) from the WebRehab Sweden national quality register database. Only patients who worked at least 50% at admission to hospital and were on full sick leave at discharge from hospital were included. QoL was measured by the EuroQol EQ-5D questionnaire. RESULTS: Patients who returned to work perceived a larger improvement in QoL from discharge to follow-up one year after injury compared to patients who had not returned to work. This difference remained after adjustment for other factors associated with improved QoL, such as having a university education, increased Extended Glasgow Outcome Scale scores and getting one's driving licence reinstated. CONCLUSION: Return to work is an important factor for change in QoL among patients with ABI, even after adjusting for other factors related to QoL. This is consistent with the hypothesis that having employment is meaningful, increases self-esteem and fosters participation in society. Thus, helping patients with ABI return to work has a positive influence on QoL. PMID- 30296174 TI - Sit-Stand Desk Software Can Now Monitor and Prompt Office Workers to Change Health Behaviors. AB - OBJECTIVE: To determine the effectiveness of a computer-based intervention designed to increase sit-stand desk usage and help reverse workplace physical inactivity. BACKGROUND: Sit-stand desks have been successful in reducing workplace sedentary behavior, but the challenge remains for an effective method to increase the usage in order to experience the health and productivity benefits. METHOD: Data collection (1-year field study with 194 workers) used a novel method of computer software that continuously recorded objective electric sit-stand desk usage, while taking into account the time a worker spends away from their desk (breaks, meetings). During the baseline period, all workers' desk usage was recorded by the software, and the intervention period consisted of software reminders and real-time feedback to all workers to change desk positions. Pooled means were calculated to determine desk usage patterns, and effect sizes and pairwise mean differences were analyzed to test for intervention significance. RESULTS: The intervention doubled desk usage by increasing ~1 change to ~2 changes per work day. There was a 76% reduction in workers who never used the sit-stand function of the desk. Medium to large effect sizes from the intervention were observed in all three primary outcome measures (desk in sitting/standing position and desk position changes per work day). CONCLUSION: These findings demonstrate an effective intervention that increased postural transitioning and interrupted prolonged inactivity while remaining at the workstation. APPLICATION: The methods and results in this research study show that we can quantify an increase in desk usage and collect aggregate data continuously. PMID- 30296176 TI - Chronic traumatic encephalopathy: what do parents of youth athletes know about it? AB - INTRODUCTION/BACKGROUND: Chronic Traumatic Encephalopathy (CTE) is a neurodegenerative disease thought to be caused by repeated head impacts and associated with deficits in cognition. Despite research and media attention, there is little science-based information available for the public. Also unclear is what the public and particularly parents of youth athletes know about CTE. The U.S. Centers for Disease Control and Prevention (CDC) surveyed parents of young athletes to fill this gap. METHODS: CDC analysed 12 CTE-related questions that appeared in Porter Novelli Public Service's 2017 SummerStyles opinion survey. Analyses focused on 674 parents of children who play in a youth sports programme. RESULTS: Half of parents had at least one child who plays contact sports. About one-third of respondents reported being somewhat or very familiar with CTE. Most parents (81.7%) have not received educational materials on CTE from a school or sports programme. Healthcare providers were the preferred source of information about CTE (70%), followed by sports coaches (54%). DISCUSSION/CONCLUSION: This analysis identified information needs related to CTE among parents of young athletes. These findings can be used by health educators to tailor educational materials to meet information needs. Educational materials that emphasize potential prevention strategies and symptom onset may be beneficial. PMID- 30296175 TI - Single clip: An improvement of the filament-perforation mouse subarachnoid haemorrhage model. AB - OBJECTIVE: The endovascular filament-perforation model turned out to become the most popular one for the reproduction of prominent pathophysiological features observed after human subarachnoid haemorrhage (SAH). However, few studies have considered methods that may minimize surgically induced injury. This study described an improved and simplified surgical procedure in which a single clip is placed at the external carotid artery (ECA). METHOD: Male C57BL/6 mice were given either a classic endovascular filament SAH model, improved endovascular filament SAH model or sham injury. Multiple strategies, including MRI with T2-weighted imaging and 18F-FDG PET/CT scanning, were performed to compare the improved and classic SAH models. RESULTS: The new method of filament model resulted a typical pathophysiological progress of early brain injury (EBI), including cerebral oedema, blood brain barrier (BBB) disruption, neuronal apoptosis and microglia activation. The improved SAH model is characterized by a shorter operation time (15.65 +/- 0.64 min vs. 21.75 +/- 0.94 min), reduced surgically induced injury (decreased 18F-FDG standardized uptake values (SUV): 1.7 +/- 0.07 vs. 2.02 +/- 0.11), and stable cerebral perfusion before SAH. CONCLUSIONS: The improved surgical technique appears to be a feasible tool for experimental and translational studies of SAH. PMID- 30296177 TI - How does visual context influence recognition of facial emotion in people with traumatic brain injury? AB - OBJECTIVE: The current study assessed recognition of facial emotional stimuli following traumatic brain injury (TBI) and examined whether performance may be influenced by emotional visual scenes. METHODS: Thirty-five patients with moderate-to-severe TBI and 55 matched controls completed the novel Angers Facial Expression in Context Task (AFECT), designed to examine recognition of facial expressions of basic emotions in both congruent and incongruent emotional visual contexts. RESULTS: In comparison with non-brain damaged adults, patients with TBI performed more poorly and slowly on both contextual conditions (congruent vs. incongruent) of the AFECT. CONCLUSION: Taken together, these results raise the possibility that adults with TBI may not fully benefit from supportive contextual cues. Also, they stress the importance of using emotional stimuli that better capture affect processing in real-world contexts and open up new avenues to better understand negative social outcomes in patients with TBI. PMID- 30296178 TI - Emotion recognition depends on subjective emotional experience and not on facial expressivity: evidence from traumatic brain injury. AB - BACKGROUND: Recognizing how others feel is paramount to social situations and commonly disrupted following traumatic brain injury (TBI). This study tested whether problems identifying emotion in others following TBI is related to problems expressing or feeling emotion in oneself, as theoretical models place emotion perception in the context of accurate encoding and/or shared emotional experiences. METHODS: Individuals with TBI (n = 27; 20 males) and controls (n = 28; 16 males) were tested on an emotion recognition task, and asked to adopt facial expressions and relay emotional memories according to the presentation of stimuli (word and photos). After each trial, participants were asked to self report their feelings of happiness, anger and sadness. Judges that were blind to the presentation of stimuli assessed emotional facial expressivity. RESULTS: Emotional experience was a unique predictor of affect recognition across all emotions while facial expressivity did not contribute to any of the regression models. Furthermore, difficulties in recognizing emotion for individuals with TBI were no longer evident after cognitive ability and experience of emotion were entered into the analyses. CONCLUSIONS: Emotion perceptual difficulties following TBI may stem from an inability to experience affective states and may tie in with alexythymia in clinical conditions. PMID- 30296179 TI - Identification of valid reference genes for circadian gene-expression studies in human mammary epithelial cells. AB - The circadian clock controls most of the physiological processes in the body throughout days and nights' alternation. Its dysregulation has a negative impact on many aspects of human health, such as obesity, lipid disorders, diabetes, skin regeneration, hematopoiesis and cancer. To date, poor is known on the molecular mechanisms that links mammary gland homeostasis to the circadian clock but recent reports highlight the importance of loss of circadian genes for mammary gland development and during tumour progression in breast cancer. Gene expression studies are then required to clarify how the circadian clock can modulates the human mammary gland development during ontology and its behaviour in physiological and oncogenic context. For this, in addition to genome-wide studies, real-time quantitative RT-PCR (qPCR) is a powerful and pertinent technique to quantify the expression of a reduced set of genes of interest in many different samples. Relative quantification of qPCR data requires the use of reference genes for normalisation. For circadian studies, reference genes expression must not oscillate in mirror of the circadian clock and must not be affected by the synchronisation protocols required in vitro to reset the circadian clock. Inappropriate selection of reference genes can consequently affect the amplitude of gene expression oscillation and bias data interpretation. Currently, no standard reference genes have been validated regarding these criteria for human mammary epithelial cells and the purpose of this study was to fill this gap. For this, we used the RefFinder tool, which combines four different algorithms, on 9 candidate reference genes. We compared reference genes stability using three different synchronisation protocols applied on four different mammary epithelial cell lines. This allowed us to define a set of reference genes in human mammary epithelial cells whose expression remains stable despite synchronisation protocols. We observed that the synchronisation of cells by serum shock was the most suitable procedure for maintaining the amplitude of oscillation of clock genes over time and we identified RPL4, RPLP0, HSPCB and TBP as an optimal combination of reference genes for the normalisation of the oscillatory expression of clock genes in human mammary epithelial cells. PMID- 30296180 TI - Employee control over scheduling of shifts and objectively measured working hour characteristics: a cross-sectional analysis of linked register and survey data. AB - We aimed to study the association of perceived control over scheduling of shifts with objectively measured working hour characteristics in shift workers. The participants were 5128 hospital employees (91% women, 85% nursing personnel, average age 43 years) in period-based work (114:45h/3 weeks) from the 2015 Finnish Public Sector study. Survey responses to a measure of control over scheduling of shifts were linked to payroll data on working hour characteristics during the 91 days preceding the survey. We used multinomial logistic regression to assess differences in dichotomized proportion of working hour characteristics (being full-time worker, number of work shifts, long work weeks (>40h and >48h/week), long work shifts (>12-h), evening and night shifts, quick returns (<11h shift interval), single days off, weekend work, >4 consecutive work shifts, and variability of shift length with cut points at 10% or 25% between employees with high, intermediate, or low control over scheduling of shifts. Analyses were adjusted for age, sex, education, full-/part-time work (where applicable), duration of shift work experience, perceived work ability, children < 18 years in the household, and overall stressfulness of the life situation. Differences between age groups, men and women, and levels of work ability were examined using interaction terms. In adjusted analyses, the proportion of full-time workers was lower among employees with intermediate control over scheduling of shifts compared to those with high control (OR 0.78, 95% CI 0.61-0.98). High proportion (>25%) of weekend work was lower among employees with low control over scheduling of shifts compared to high control (OR 0.75, 95% CI 0.61-0.93). High proportion (>25%) of having >4 consecutive work shifts was associated with lower control over scheduling of shifts (OR 1.35, 95% CI 1.13-1.62). Variability of shift length was lower among employees with intermediate and low control over scheduling of shifts compared to those with high control (OR 0.78, 95% CI 0.66 0.93; OR 0.62, 95% CI 0.51-0.75, respectively). No association was observed between the level of control over scheduling of shifts and high proportion of long work weeks (>25% of >40h weeks and >10% of >48h weeks), long work shifts (>25%), quick returns (>25%), single days off (>25%), and evening or night shifts (>10%) in the whole sample. In subgroup analyses, women with low control over scheduling shifts had lower odds ratio (OR 0.58, 95% CI 0.37-0.91) and men had higher odds ratio (OR 2.97, 95% CI 1.26-6.98) for large proportion of >12-h shifts. In conclusion, the employees with high control over scheduling of shifts had slightly more often unsocial working hour characteristics than those with intermediate or low control over scheduling of shifts. The findings, however, suggest that good work time control in shift work can be possible without compromising shift ergonomics. PMID- 30296181 TI - Circadian variations in the onset of aortic dissection in northern China. AB - This study explored the periodic changes in the onset of aortic dissection in a single center in northern China, with the goal to improve predictability and prevention. We collected the clinical data of 1121 patients from Hebei Province treated for acute aortic dissection at Fuwai Hospital between January 2010 and December 2016. The patterns of aortic dissection during different periods of each day, each month, and each quarter of a year were analyzed. Variations in the number of cases were summarized for weekdays, weekends, and different periods of a day in each season. We compared the differences in gender, age, body mass index, Marfan syndrome, hypertension, and the type of aortic dissection during different time periods and different seasons. In the study, 774 patients (69.1%) with type A aortic dissection and 347 patients (30.9%) with type B aortic dissection were included. The average age of 1121 patients was 51.4 +/- 12.0 years. Overall, the peak period for the onset of aortic dissection in a day was between 13:00 and 18:00. There was no statistically significant difference in the number of cases between weekdays and weekend (P = 0.94). Most cases occurred in winter (30.9%); the rate of onset was the lowest in summer (16.6%). No statistically significant difference was observed between male and female patients in terms of variations during different periods of a day (P = 0.45) and seasons (P = 0.12). In conclusion, aortic dissection displayed circadian and seasonal patterns in northern China. Onset of the disease peaked between 13:00 and 18:00 in a day. Winter was the peak season for the onset of acute aortic dissection, regardless of sex, type of dissection and age. PMID- 30296182 TI - Semaglutide once-weekly: improved efficacy with a new safety warning. AB - INTRODUCTION: Semaglutide once-weekly glucagon-like peptide-1 receptor agonist (GLP-1 RA) injection has been approved as an adjunct to diet and exercise to improve glycemic control in type 2 diabetes mellitus (T2DM). Areas Covered: The safety and efficacy of the semaglutide once-weekly injection are reviewed using results from preliminary pharmacology studies and later-phase randomized control trials (RCTs) and meta-analyses. Semaglutide once-weekly is compared to placebo and active comparators for T2DM in the SUSTAIN clinical trial series, with outcomes of: glycemic control, weight loss, major adverse cardiovascular events, and adverse effects. Risk for diabetic retinopathy complications (DRCs) is reviewed in detail, due to significantly higher risk for DRCs seen in SUSTAIN 6. SUSTAIN 6 is the first instance of a GLP-1 RA demonstrating significantly increased risk for DRCs. Semaglutide's current regulatory approvals, practice considerations, and cost-effectiveness compared to similar therapies are also considered. Expert Commentary: Semaglutide demonstrates high glycemic efficacy and favorable safety profile, and reduces the risk for cardiovascular events. Mild to moderate gastrointestinal events and retinopathy complications were more common with semaglutide compared to placebo, though serious adverse events were similar to controls and infrequent. Improved clinical efficacy should be carefully weighed against the risk for GI and retinopathy complications. PMID- 30296183 TI - Monogenic forms of lipodystrophic syndromes: diagnosis, detection, and practical management considerations from clinical cases. AB - BACKGROUND: Lipodystrophic syndromes are rare diseases of genetic or acquired origin characterized by partial or generalized lack of body fat. Early detection and diagnosis are crucial to prevent and manage associated metabolic dysfunctions, i.e. insulin resistance, dyslipidemia, fatty liver, and diabetes, and to provide appropriate genetic counseling. By means of several representative case studies, this article illustrates the diagnostic and management challenges of lipodystrophic syndromes. REVIEW: Berardinelli-Seip congenital lipodystrophy (BSCL) is typically diagnosed at birth, or soon thereafter, with generalized lipoatrophy and hepatomegaly secondary to hepatic steatosis. Physicians must also consider this diagnosis in adults with atypical non-autoimmune diabetes, hypertriglyceridemia, and a lean and muscular phenotype. The BSCL1 subtype due to mutations in the AGPAT2 gene can have an unusual presentation, especially in neonates and infants. Particular attention should be paid to infants presenting failure to thrive who also have hepatomegaly and metabolic derangements. The BSCL2 sub-type due to mutations in the BSCL gene tends to be more severe than BSCL1, and is characterized by greater fat loss, mild intellectual disability, earlier onset of diabetes, and higher incidence of premature death. Effective management from an earlier age may moderate the natural disease course. Partial lipodystrophies may easily be confused with common central obesity and/or metabolic syndrome. In patients with unexplained pancreatitis and hypertriglyceridemia, lipodystrophies such as familial partial lipodystrophy type 2 (FPLD2; Dunnigan type, due to LMNA mutations) should be considered. Oral combined contraceptives, which can reveal the disease by inducing severe hypertriglyceridemia, are contraindicated. Endogenous estrogens may also lead to "unmasking" of the FPLD2 phenotype, which often appears at puberty, and is more severe in females than males. CONCLUSIONS: Diet and exercise, adapted to age and potential comorbidities, are essential prerequisites for therapeutic management of lipodystrophic syndromes. Metreleptin therapy can be useful to manage lipodystrophy-related metabolic complications. PMID- 30296184 TI - More than hours of work: fatigue management during high-intensity maritime operations. AB - OBJECTIVES: This study examines the impacts of peak summer demand on operator workload and fatigue in a maritime environment. METHODS: Participants (n = 12) were senior shipboard personnel who were working during the summer "double sailing" period for a roll-on roll-off ferry service. Wrist actigraphy was used to determine sleep opportunity and sleep duration, as well as prior sleep, total wake time, performance and alertness at the beginning and end of work periods. RESULTS: Contrary to expectations, sleep was significantly greater, and both subjective estimates of fatigue and objective neurobehavioral performance were not impacted negatively by periods of increased work intensity. CONCLUSIONS: This study highlights a number of features of a fatigue-risk management system that appear to have been instrumental in ensuring adequate sleep and performance was maintained throughout periods of increased operational intensity. As a simple colloquial description of the fatigue-risk management system at play in this operation, it was fine to "work hard" if you were able to "sleep hard" as well. PMID- 30296185 TI - Real-world anaplastic lymphoma kinase (ALK) rearrangement testing patterns, treatment sequences, and survival of ALK inhibitor-treated patients. AB - BACKGROUND: The anaplastic lymphoma kinase (ALK) treatment landscape is crowded following recent ALK inhibitor approvals, and updated information on real-world treatment patterns in advanced non-small-cell lung cancer (aNSCLC) with ALK rearrangement (ALK+) is needed. METHODS: This retrospective US cohort study used Flatiron Health's longitudinal electronic health record (EHR)-derived database. Patients (>= 18 years old) diagnosed with stage IIIB/IV aNSCLC, with documented ALK rearrangement and >=2 visits after January 1, 2011 were followed until February 28, 2016. Patients enrolled on a clinical trial or exposed to ALK inhibitors other than crizotinib or ceritinib were excluded. Treatment patterns, time and type of biomarker testing, and overall survival (OS) were analyzed. RESULTS: Median age (n = 300) was 62.5 years; 55% female; 48% non-smokers; 8.7% central nervous system (CNS) metastases at diagnosis. Overall, 73% and 86% received their first ALK biomarker test before/at diagnosis, or before/during first-line treatment, respectively. In total, 90.0%, 78.1%, and 74.7% received first-, second-, and third-line therapy, respectively. Most patients received ALK targeted treatment; 62% received crizotinib, of which 21% reported a dose reduction. Progression was the most common reason for crizotinib (78%) and ceritinib (41%) discontinuation. Median OS was 29.4 months (95% CI =24.7-39.6) overall; 27.1 months (95% CI =22.0-35.0) in patients with CNS metastases, and 36.9 months (95% CI =25.1-not reached) without. CONCLUSIONS: Despite widespread crizotinib use in patients with ALK+ aNSCLC, a high proportion of patients progressed. Ongoing analyses of EHR-derived cohorts are valuable in assessing real-world testing rates and therapeutic use of ALK inhibitors. PMID- 30296186 TI - Thyroid disease in the perimenopause and postmenopause period. AB - The interpretation of thyroid function tests should be cautiously made during the perimenopause and postmenopause period bearing in mind that physiologic changes do exist in this group of women in terms of secretion and metabolism of thyrotropin and thyroid hormones. Moreover the incidence of thyroid disorders increases in postmenopausal and elderly women. There is no consensus for screening postmenopausal women even though there is well-known evidence about the effect of thyroid status on cognitive function, cardiovascular risk, bone turnover, and longevity. The diagnosis of any thyroid disorder is challenging in these patients because the symptoms are more subtle and attributed to menopausal symptoms. Management requires more attention in this population than that of younger groups, because high doses of L-thyroxine can lead to cardiac complications and increased bone turnover. Furthermore radio-iodine is preferred in treatment of hyperthyroidism in older patients. The risk of nodular thyroid disease and thyroid cancers increases in this group. Although the diagnostic approach is the same as for young patients, the risk of surgery is high and disease prognosis is worse. Women with any form of thyroid disease should be treated according to the current guidelines. Decision for menopausal hormonal therapy should be individualized regardless of the concomitant presence of thyroid disorders. PMID- 30296187 TI - Targeting central nervous system pathologies with nanomedicines. AB - One of the major challenges in drug development is the delivery of therapeutics to the central nervous system (CNS). The blood-brain barrier (BBB), which modulates the passage of molecules from the CNS, presents a formidable obstacle that limits brain uptake of therapeutics and, therefore, impedes the treatment of multiple neurological pathologies. Targeted nanocarriers present an excellent opportunity for drug delivery into the brain leveraging on endogenous receptors to transport therapeutics across the BBB endothelium. Receptor-mediated transport endows multiple benefits over other conventional delivery methods such as the transient permeabilization of the BBB or the direct depositioning of intracranial depots. Herein, different strategies for nanocarrier targeting to the CNS are discussed, highlighting the challenges and recent developments. PMID- 30296188 TI - Tisagenlecleucel-T for the treatment of acute lymphocytic leukemia. AB - INTRODUCTION: Cellular immunotherapy with autologous or allogeneic T cells, genetically engineered to express chimeric antigen receptors (CARs) or T-cell receptors, in order to redirect their cytotoxic specificity toward malignant cells, is emerging as a promising new treatment modality. The most advanced approach in clinical development is the use of anti-CD19 CAR T-cells for the treatment of CD19+ B-cell malignancies, including acute lymphocytic leukemia (ALL). Areas covered: Recently, the Food and Drug Administration (FDA) approved the first anti-CD19 CAR T-cell product, tisagenlecleucel, for the treatment of pediatric and young adult patients with relapsed/refractory ALL. In this overview, we described the advances in the field, including a summary of clinical trials with tisagenlecleucel in ALL published to date. Expert opinion: CAR T-cell therapy has been developed in the context of small clinical studies and very few centers have had to deal with the challenges of managing CAR T-cells administration. However, this approach is likely to become a standard option for patients with relapsed/refractory B-cell lineage ALL. PMID- 30296190 TI - Clostridium difficile infection in oncology patients: epidemiology, pathophysiology, risk factors, diagnosis, and treatment. AB - Clostridium difficile infection (CDI) is one of the most common healthcare associated infections in the United States. Its incidence has been increasing in the recent years despite preventative measures. CDI increases annual expenses by 1.5 billion dollars. Cancer patients are at higher risk to acquire CDI, as explained by their frequent exposure to risk factors. CDI in cancer patients is associated with higher mortality rates and prolonged hospitalization. Furthermore, CDI affects the course of the disease by delaying treatments such as chemotherapy. Chemotherapeutics drugs are considered independent risk factors for CDI. This review discusses Clostridium difficile infection in cancer patients, including those who are receiving chemotherapy. Herein, we summarize recent data regarding the epidemiology, risk factors, including chemotherapy regimens, pathogenesis, diagnostic techniques and treatment options, including newer agents. Method: A literature search was performed using the PubMed and Google Scholar databases. The MeSH terms utilized in different combinations were 'clostridium difficile', 'neoplasia/cancer/oncology', 'chemotherapy', 'diagnosis', and 'treatment', in addition to looking up each treatment option individually to generate a comprehensive search. The articles were initially screened by title alone, followed by screening through abstracts. Full texts of pertinent articles (including letters to editors, case reports, case series, cohort studies, and clinical trials) were included in this review. PMID- 30296189 TI - Parental stress and paediatric acquired brain injury. AB - OBJECTIVE: Studies on parental stress following childhood acquired brain injury (ABI-including brain tumours (BT) and other brain injuries) are scarce. The aim of this study was to assess maternal stress in a sample of children and adolescents diagnosed with severe paediatric ABI. METHODS: Seventy-eight French speaking mothers of 37 with BT and 41 with other ABIs completed the Paediatric Inventory for Parents (PIP), the State-Trait Anxiety Inventory (STAI) and the Family Assessment Device (FAD) at a mean time since diagnosis of 1.5 years. RESULTS: The PIP correlated significantly with the STAI and the FAD. Socio demographic factors, such as the age of mother and child, and the mother's educational level, were correlated with both maternal stress and anxiety. Maternal stress scores were comparable between groups. Emotional functioning was the most markedly affected domain, followed by parental role. CONCLUSIONS: Emotional stress as assessed by the PIP in mothers of children with ABI is significant and should motivate specific psychosocial interventions. PMID- 30296191 TI - The protective role of endogenous n-3 polyunsaturated fatty acids in Tau Alzheimer's disease mouse model. AB - OBJECTIVES: The role of n-3 polyunsaturated fatty acid (PUFA) as the main docosahexaenoic acid (DHA) in Alzheimer's disease (AD) remains controversial. Our study aimed to provide detailed information about the role of endogenous n-3 PUFAs in AD. METHODS: Here, we generated a fat-1/tau transgenic mouse AD model by crossing female tau mice with male fat-1 mice to exclude confounding variables associated with the benefit of a DHA diet in these AD mice models. PUFAs presented in these AD models were detected by gas chromatography, and the role of endogenous n-3 PUFAs was assessed by lifespan survival assay, behavioral, pathologic, and molecular biology testing as well as imaging of cerebral vasculature. RESULTS: Endogenous n-3 PUFAs were shown to improve the memory and learning ability of AD mice. One possible reason for this improvement is the reduced formation of neurotrophic factors (NFTs) and Abeta amyloid plaques which usually damage hippocampal neurons. Additionally, endogenous n-3 PUFAs were demonstrated to protect cerebral vascular of AD mice, thereby increasing brain metabolism. Besides, endogenous n-3 PUFAs were observed to extend of the overall survival of tau mouse models. CONCLUSION: Endogenous n-3 PUFAs delayed the onset of Alzheimer's disease caused by tau protein dysfunction, alleviating related symptoms and significantly prolonging survival in vivo. PMID- 30296192 TI - Postoperative Management of Resected Brain Metastases: When Can Radiotherapy Be Deferred? AB - The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 67-year-old woman was diagnosed 17 months ago with stage IIIB non-small-cell lung cancer (NSCLC; adenocarcinoma), without a targetable mutation, for which she received chemotherapy and thoracic radiotherapy. She developed new-onset gait ataxia, nausea, morning emesis, and headaches. A brain magnetic resonance imaging (MRI) scan demonstrated a 3.2-cm left cerebellar enhancing metastatic lesion, with surrounding vasogenic edema and mass effect, and three additional enhancing cortical, parenchymal lesions, each < 1.2 cm in maximum diameter, and none with significant mass effect ( Fig 1A ). A restaging positron emission tomography scan revealed no new sites of metastatic disease and no obvious intrathoracic progression. She underwent craniotomy, with piecemeal resection of the cerebellar metastatic lesion that proved to be recurrent lung cancer ( Fig 1B ). Her medical history was significant for mild hypertension and diet-controlled type II diabetes. She had smoked one pack a day for 32 years and had quit 3 years earlier. Postoperatively, her neurologic symptoms resolved, and physical and neurologic examinations were unrevealing; she had an Eastern Cooperative Oncology Group performance status (PS) of 0 and a Mini Mental State Examination (MMSE) score of 29 of 30. A 3-week postoperative MRI scan confirmed the presence of 1-cm right frontal, 1.2-cm right parietal, and 1.2 cm left temporal enhancing lesions with minimal enhancement and no evidence of mass effect or edema. In addition, there was an ill-defined residual tumor bed, estimated to be approximately 3.7 cm in maximum diameter ( Fig 1C ). The patient was no longer receiving any steroids and was not receiving any anticonvulsants. Because of the residual three brain metastatic lesions, as well as the consideration of a high risk of surgical failure, she was referred for radiotherapy. PMID- 30296194 TI - Introduction of universal infant hepatitis B immunisation in the UK- paving the way to elimination. AB - In May 2016, the World Health Assembly ratified the first ever Global Health Sector Strategy (GHSS) on Viral Hepatitis to eliminate viral hepatitis as a public health threat by 2030. In pursuit of this elimination goal and recognising that hepatitis control through immunisation is an essential foundation of a hepatitis B prevention programme, the World Health Organization set out vaccine coverage targets for both universal and selective childhood immunisation programmes, focusing on preventing mother to child transmission. In August 2017 the UK introduced a hexavalent (DTaP/IPV/Hib/HepB) combination vaccine into the routine childhood immunisation programme, replacing the pentavalent vaccine given to all infants at 8, 12 and 16 weeks. With the addition of the 6th component to protect against hepatitis B the UK finally introduced universal hepatitis B immunisation. Prior to that, the UK had a selective immunisation policy targeting high risk groups for hepatitis B - including infants born to hepatitis B infected mothers. We tell the story of hepatitis B vaccination in the UK, and how we have evolved from selective to a universal infant immunisation programme, the factors considered in hepatitis B vaccine policy decision-making, and the progress towards elimination of viral hepatitis as a public health threat. PMID- 30296193 TI - Multirefractory primary immune thrombocytopenia; targeting the decreased sialic acid content. AB - Patients with multirefractory immune thrombocytopenia (ITP) have limited treatment options. Recent data suggest that specific anti-platelet antibodies may cause destruction of platelets by favoring platelet loss of sialic acid. In this multicenter study 35 patients with ITP, including 16 with multirefractory disease, were analyzed for antiplatelet-antibodies, thrombopoietin (TPO) levels, and platelet desialylation. In selected cases, responses to a novel treatment strategy using oseltamivir were tested. We found that antibodies against GPIbalpha were overrepresented in multirefractory patients compared to responders (n = 19). In contrast to conventional ITP patients, multirefractory patients exhibited a significant increased platelet activation state (granule secretion) and desialylation (RCA-1 binding) (p < 0.05), and a trend toward higher plasma TPO concentrations. The decreased sialic acid content seemed to be restricted to platelet glycoproteins, since other plasma proteins were not hypoglycosylated. A total of 10 patients with multirefractory ITP having remarkable loss of platelet terminal sialic acids were given oseltamivir phosphate. When the antiviral drug was combined with TPO receptor agonists (TPO-RAs) or with immunosuppressant drugs, platelet responses were observed in 66.7% of patients. All responding patients presented with antibodies reactive only against GPIbalpha. These findings suggest that desialylation may play a key pathogenic role in some multirefractory ITP patients, and provide diagnostic tools for the identification of such patients. Furthermore, we show that sialidase inhibitor treatment in combination with therapies that help to increase platelet production can induce sustained platelet responses in some patients with anti-GPIbalpha -mediated thrombocytopenia that have failed previous therapies. PMID- 30296195 TI - Isolated central nervous system Rosai-Dorfman disease and breast cancer: an unusual presentation. AB - The association between Rosai-Dorfman Disease (RDD) and cancer was reported for the first time in 1984. However, there are still a small number of reports of this association. We describe a 60-year-old woman who presented with a focal onset motor seizure followed by tonic-clonic generalization and persistent headache. Magnetic Resonance Imaging disclosed an irregular hyperintense lesion in T2 and vasogenic edema in the left parietal region. Immunohistochemical analysis of a biopsy fragment was positive for protein S-100 and CD68 and negative for CD1a, compatible with the diagnosis of RDD. She previously had breast cancer six years earlier and had used tamoxifen for two years and anostrozol for three years after diagnosis of cancer. RDD has been already associated with different cancers, such as Hodgkin's lymphoma, non-Hodgkin's lymphoma, follicular lymphoma, melanoma, adenocarcinoma and small cell lung cancer. As far as we know, this is the first report of an association between breast cancer and RDD. PMID- 30296196 TI - Iodine-125 seed implantation combined with arterial chemoembolization therapy for pain palliation in metastatic bone cancer: a retrospective study. AB - Bone metastases are the most common sites for malignant tumors. Patients who failed to respond to initial first-line treatment with bisphosphonates usually suffer from extreme pain. The aim of this study was to observe the efficacy of arterial chemoembolization combined with Iodine-125 seed implantation in the treatment of bone metastatic cancer pain. All 14 patients with metastatic bone tumor wo failed first-line treatment underwent arterial chemoembolization the day before the implantation of the particles. A computer stereoscopic TPS was used to design the treatment plans, the number and dose of particles required for implantation. Pain relief was evaluated using several parameters such as Visual Analog Scale (VAS) and Verbal Rating Scales (VRS). Pain intensity was measured pre-operation and 1-week, 1-month, 3-month after the treatment. Meanwhile, we also assessed tumor size using computer tomography (CT). Pain palliation was observed in 35.7% (5/14), 57.1% (8/14), and 78.6% (11/14) of all patients at 1 week, 1-month and 3-month post treatment. Likewise, our analysis showed that the combination therapy resulted in a significant decrease of VAS score (6.71 +/- 0.49 before treatment vs 3.36 +/- 0.40 at 3 month post treatment) and overall responding rate of 92.0% using VRS pain assessment. Consistently, tumor size was reduced from 42.16 +/- 10.32 before treatment to 29.11 +/- 8.73 at 3 months post treatment. No serious complications were detected. Our study demonstrate that the combination of arterial chemoembolization and 125I particles resulted in evident pain relief and reduction of tumor burden, suggesting that the combination treatment could be a feasible and promising therapy for bone tumor management. PMID- 30296197 TI - Recent changes in the epidemiology of Neisseria meningitidis serogroup W across the world, current vaccination policy choices and possible future strategies. AB - Invasive meningococcal disease (IMD) is a serious disease that is fatal in 5-15% and disabling in 12-20% of cases. The dynamic and unpredictable epidemiology is a particular challenge of IMD prevention. Although vaccination against meningococcal serogroups A (MenA), MenC and, more recently, MenB, are proving successful, other serogroups are emerging as major IMD causes. Recently, surges in MenW incidence occurred in South America, Europe, Australia and parts of sub Saharan Africa, with hypervirulent strains being associated with severe IMD and higher fatality rates. This review describes global trends in MenW-IMD epidemiology over the last 5-10 years, with emphasis on the response of national/regional health authorities to increased MenW prevalence in impacted areas. Several countries (Argentina, Australia, Chile, the Netherlands and UK) have implemented reactive vaccination campaigns to reduce MenW-IMD, using MenACWY conjugate vaccines. Future vaccination programs should consider the evolving epidemiology of MenW-IMD and the most impacted age groups. PMID- 30296198 TI - Evaluation of similar quality attribute characteristics in SB5 and reference product of adalimumab. AB - Biosimilars are biologic products that are highly similar to a licensed reference product in terms of quality, safety, and efficacy. SB5 is a biosimilar of Humira(r) (adalimumab) developed by Samsung Bioepis. To demonstrate its biosimilarity in quality to Humira(r), we performed a comprehensive characterization in terms of structure, physicochemical properties, and biological properties following the International Conference on Harmonization, US Food and Drug Administration, and European Medicines Agency guidelines. We analyzed all available batches of SB5 and more than 100 EU- and US-sourced lots of Humira(r) using state-of-the-art methods whenever possible, and compared the two sets of data. The structural properties comprised primary and higher-order structures and N-glycosylation. The physicochemical characteristics were categorized into liquid chromatographic patterns and electrophoretic pattern concerning size and charge heterogeneity. The biological properties were examined by in vitro functional assays. Overall, SB5 and Humira(r) were shown to be similar to each other in terms of quality attributes. For some of the quality attributes, minor differences were observed. However, the observed differences have been adequately addressed and demonstrated these do not translate into clinically meaningful differences in terms of safety, purity, and potency. PMID- 30296199 TI - Lp-PLA2 as a risk factor of early neurological deterioration in acute ischemic stroke with TOAST type of large arterial atherosclerosis. AB - INTRODUCTION: Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a well-known risk factor of atherosclerotic vascular diseases. Nevertheless, its role in the acute phase of ischemic stroke is still unclear. The aim of this study is to identify the relationship between Lp-PLA2 levels and early neurological deterioration (END) in acute ischemic stroke patients with Trial of Org 10 172 in Acute Stroke Treatment (TOAST) subtype of large arterial atherosclerosis (LAA). METHODS: We enrolled Chinese patients with first ever acute ischemic stroke admitted to Neurology Department of Shenzhen Second People's Hospital within 48 h from onset of symptoms during January - November 2015. Demographic and laboratory information were collected while END was defined as an increase in the National Institute of Health Stroke Scale score by >= 1 point in motor power, or >= 2 points in the total score within 10 days after admission. RESULTS: Overall 181 patients were involved; END was diagnosed in 30 patients within 10 days after admission. The odds ratio for END increased with increasing levels of Lp-PLA2 (intermediate level, OR = 1.96, 95%CI 1.02-4.27, p = 0.041; high level, OR = 2.99, 95%CI 1.26-5.73, p = 0.023). Conclution: Intermediate and high level of Lp PLA2 was identified as independent predictor of END in multivariate analysis. Lp PLA2 could be valued as a risk factor of END in patients with acute ischemic stroke with TOAST subtype of LAA. PMID- 30296200 TI - Expression, purification, and characterization of N-terminal His-tagged proteins with mutations in zinc finger 3 of zinc finger protein ZNF191(243-368). AB - Zinc finger protein ZNF191(243-368), the zinc finger region of ZNF191, is potentially associated with cell proliferation in hepatocellular carninoma. A His tag expression system was used to express and purify proteins with mutations in the zinc finger 3 of ZNF191(243-368) for analysis of protein properties, structure, and functions. The purification of the His-tag fusion proteins was simpler and faster than that of the ZNF191(243-368) inclusion bodies. The properties and structures of the His-tag fusion mutant proteins were investigated using spectrographic techniques and DNA hydrolysis experiment. The His6-tag system could be used to express ZNF191(243-368). The presence of the His6-tag at the N-terminus of ZNF191(243-368) did not evidently affect its properties and structure. However, the site-directed mutations in zinc finger 3 affected the structure of the protein. The DNA hydrolase activity of His6-ZF-F3/H4 suggested that four histidines in zinc finger 3 might form a structure similar to that of the active center in a hydrolase. This work reports that continuous histidines need to form a certain structure for specific functions, and provides new insights into the design of an artificial nuclease. PMID- 30296202 TI - Participants' perceptions of an aphasia-friendly occupational therapy home program. AB - BACKGROUND: Upper extremity impairments post-stroke impact participation in valued occupations. Home programs are used to extend the frequency and amount of upper extremity practice for people post-stroke, but novel ways of increasing adherence to these programs is needed to ensure intense repetitive practice. OBJECTIVES: The purpose of this process evaluation, was to examine the perceptions of people with aphasia as it relates to modifications to home programs that could influence participation, specifically listening to music and aphasia-friendly adaptations of written materials. METHODS: Seven people with chronic aphasia completed an upper extremity home program that included the use of music and aphasia-friendly modified materials (ClinicalTrials.gov ID:2016/06/18). After the home program, participants completed semi-structured interviews to understand their perceptions of the program and the modifications. RESULTS: Five themes were identified including (1) music, (2) activities, (3) instructions, (4) logistics, and (5) progress. Most participants perceived music as helpful, but a few reported it being distracting. Participants found the variety of activities helpful as well as specific characteristics of the instructions such as photographs and images. Some participants expressed elements of the home program to be barriers to practice such as using the activity monitors and logbook, which required assistance at times. Finally, participants noted their own progress resulting from the program and liked that they could adjust the intensity of the program as they progressed. CONCLUSIONS: Overall participants in this study with aphasia perceived the modifications to home programs including aphasia friendly written instructions and music to facilitate successful home practice. PMID- 30296201 TI - PHYTOCHROME INTERACTING FACTOR1 interactions leading to the completion or prolongation of seed germination. AB - In Arabidopsis thaliana, the basic Helix Loop Helix transcription factor, PHYTOCHROME INTERACTING FACTOR1 (PIF1) is known to orchestrate the seed transcriptome such that, ultimately, proteins repressing the completion of germination are produced in darkness. While PIF1-mediated control of abscisic acid (ABA) and gibberellic acid (GA) anabolism/catabolism is indirect, PIF1 action favors ABA while discriminating against GA, firmly establishing ABA's repressive influence on the completion of germination. The result is tissue that is more sensitive to and producing more ABA; and is less responsive to and deficient in GA. Illumination of the appropriate wavelength activates phytochrome which enters the nucleus, and binds to PIF1, initiating PIF1's phosphorylation by diverse kinases, subsequent polyubiquitination, and hydrolysis. One mechanism by which phosphorylated PIF1 is eliminated from the cells of the seed upon illumination involves an F-BOX protein, COLD TEMPERATURE GERMINATING10 (CTG10). Discovered in an unbiased screen of activation tagged lines hastening the completion of seed germination at 10 degrees C, one indirect consequence of CTG10 action in reducing PIF1 titer, should be to enhance the transcription of genes whose products work to increase bioactive GA titer, shifting the intracellular milieu from one that is repressive to, toward one conducive to, the completion of seed germination. We have tested this hypothesis using a variety of Arabidopsis lines altered in CTG10 amounts. Here we demonstrate using bimolecular fluorescence complementation that PIF1 interacts with CTG10 and show that, in light exposed seeds, PIF1 is more persistent in ctg10 relative to WT seeds while it is less stable in seeds over-expressing CTG10. These results are congruent with the relative transcript abundance from three genes whose products are involved in bioactive GA accumulation. We put forth a model of how PIF1 interactions in imbibed seeds change during germination and how a permissive light signal influences these changes, leading to the completion of germination of these positively photoblastic propagules. PMID- 30296203 TI - The role of cellular contact and TGF-beta signaling in the activation of the epithelial mesenchymal transition (EMT). AB - The epithelial mesenchymal transition (EMT) is one step in the process through which carcinoma cells metastasize by gaining the cellular mobility associated with mesenchymal cells. This work examines the dual influence of the TGF-beta pathway and intercellular contact on the activation of EMT in colon (SW480) and breast (MCF7) carcinoma cells. While the SW480 population revealed an intermediate state between the epithelial and mesenchymal states, the MC7 cells exhibited highly adhesive behavior. However, for both cell lines, an exogenous TGF-beta signal and a reduction in cellular confluence can push a subgroup of the population towards the mesenchymal phenotype. Together, these results highlight that, while EMT is induced by the synergy of multiple signals, this activation varies across cell types. PMID- 30296204 TI - Comprehensive characterisation of the heterogeneity of adalimumab via charge variant analysis hyphenated on-line to native high resolution Orbitrap mass spectrometry. AB - Charge variant analysis is a widely used tool to monitor changes in product quality during the manufacturing process of monoclonal antibodies (mAbs). Although it is a powerful technique for revealing mAb heterogeneity, an unexpected outcome, for example the appearance of previously undetected isoforms, requires further, time-consuming analysis. The process of identifying these unknowns can also result in unwanted changes to the molecule that are not attributable to the manufacturing process. To overcome this, we recently reported a method combining highly selective cation exchange chromatography-based charge variant analysis with on-line mass spectrometric (MS) detection. We further explored and adapted the chromatographic buffer system to expand the application range. Moreover, we observed no salt adducts on the native protein, also supported by the optimal choice of MS parameters, resulting in increased data quality and mass accuracy. Here, we demonstrate the utility of this improved method by performing an in-depth analysis of adalimumab before and after forced degradation. By combining molecular mass and retention time information, we were able to identify multiple modifications on adalimumab, including lysine truncation, glycation, deamidation, succinimide formation, isomerisation, N terminal aspartic acid loss or C-terminal proline amidation and fragmentation along with the N-glycan distribution of each of these identified proteoforms. Host cell protein (HCP) analysis was performed using liquid chromatography-mass spectrometry that verified the presence of the protease Cathepsin L. Based on the presence of trace HCPs with catalytic activity, it can be questioned if fragmentation is solely driven by spontaneous hydrolysis or possibly also by enzymatic degradation. PMID- 30296205 TI - HIV and tuberculosis co-infection in a highly HIV-infected population of rivers state, Nigeria. AB - Human Immunodeficiency Virus (HIV) and tuberculosis (TB) are considered as key players in the global health scene. This study sought to determine the prevalence of TB among HIV-positive attendees of the Directly Observed Treatment of Short Course (DOTS) program at the military hospital in Port Harcourt. The association of HIV prevalence with gender and age as risk factors was also determined. A total of 200 patients aged 15-65 years were screened. Re-screening for HIV was done for confirmation. The overall prevalence for anti-TB antibodies amongst HIV positive individuals was 14.0% (7.5% in males and 6.5% in females) while HIV prevalence following re-screening was 92%. It was observed that based on employment status and level of education, the highest HIV prevalence was seen in unemployed individuals and individuals with no formal education. The result showed that 29.9% of the HIV seropositives were males while 70.1% were females. Sex-related prevalence of HIV-TB coinfection within groups indicated significantly higher co-infection rates (P < 0.05) among males (23.1%) than females (9.6%). Age-related prevalence of HIV-TB coinfection within groups showed that co-infection was significantly greater (P < 0.05) in ages below 30 years (21.2%) than in their counterparts 30 years and above (9.6%). This study confirmed the presence of TB co-infections among HIV-positive individuals in Port Harcourt, Nigeria. Considering the role of TB in driving the HIV pandemic, it is imperative that HIV-positive patients are screened for TB infection regularly to reduce the scale of active HIV-TB co-infection. PMID- 30296206 TI - Zn-fortified cereal grains in field-grown barley by enhanced root cytokinin breakdown. AB - Zinc (Zn) is an essential element in human nutrition. The concentration of Zn in cereals, which is a staple food in developing countries, is often too low thus contributing to Zn malnutrition in nearly two billion people worldwide. We have reported recently that transgenic barley plants expressing a cytokinin-degrading CYTOKININ OXIDASE/DEHYDROGENASE (CKX) gene in their roots form a larger root system and accumulate a higher concentration of Zn in their grains when grown under greenhouse conditions. Here, we have tested this trait under field conditions. Four independent pEPP:CKX lines accumulated an up to 30% higher Zn concentration in their grains as compared to the untransformed control suggesting that this is a stable trait. The increased Zn concentration exceeded the limit set by the HarvestPlus program for wheat. We, therefore, propose that root enhancement achieved by increased degradation of cytokinin in roots can be a sustainable strategy to combat malnutrition caused by Zn deficiency. PMID- 30296207 TI - Biological Event Trigger Identification with Noise Contrastive Estimation. AB - Biological Event Extraction is an important task towards the goal of extracting biomedical knowledge from the scientific publications by capturing biomedical entities and their complex relations from the texts. As a crucial step in event extraction, event trigger identification, assigning words with suitable trigger category, has recently attracted substantial attention. As triggers are scattered in large corpus, traditional linguistic parsers are hard to generate syntactic features from them. Thereby, trigger sparsity problem restricts the model's learning process and becomes one of the main hinder in trigger identification. In this paper, we employ Noise Contrastive Estimation with Multi-Layer Perceptron model for solving triggers' sparsity problem. Meanwhile, in the light of recent advance in word distributed representation, word-embedding feature generated by language model is utilized for semantic and syntactic information extraction. Finally, experimental study on commonly used MLEE dataset against baseline methods has demonstrated its promising result. PMID- 30296208 TI - 3D Measurements of Acceleration-Induced Brain Deformation via Harmonic Phase Analysis and Finite-Element Models. AB - OBJECTIVE: To obtain dense spatiotemporal measurements of brain deformation from two distinct but complementary head motion experiments: linear and rotational accelerations. METHODS: This study introduces a strategy for integrating harmonic phase analysis of tagged magnetic resonance imaging (MRI) and finite element models to extract mechanically representative deformation measurements. The method was calibrated using simulated as well as experimental data, demonstrated in a phantom including data with image artifacts, and used to measure brain deformation in human volunteers undergoing rotational and linear acceleration. RESULTS: Evaluation methods yielded a displacement error of 1.1 mm compared to human observers, and strain errors between 0.1 0.2% (mean std. dev.) for linear acceleration and 0.7 0.3% for rotational acceleration. In the presence of inconsistent or missing data, we demonstrate an approach that can provide an error reduction of 86%. Analysis of results shows consistency with 2D motion estimation, agreement with external sensors, and the expected physical behavior of the brain. CONCLUSION: Mechanical regularization is useful for obtaining dense spatiotemporal measurements of in-vivo brain deformation under different loading regimes. SIGNIFICANCE: The measurements suggest that the brain's 3D response to mild accelerations includes distinct patterns observable using practical MRI resolutions. This type of measurement can provide validation data for computer models for the study of traumatic brain injury (TBI). PMID- 30296209 TI - Half Thresholding Pursuit Algorithm for Fluorescence Molecular Tomography. AB - OBJECTIVE: Fluorescence Molecular Tomography (FMT) is a promising optical tool for small animal imaging. The -norm regularization has attracted attention in the field of FMT due to its ability in enhancing sparsity of solution and coping with the high ill-posedness of the inverse problem. However, efficient algorithm for solving the non-convex regularized model deserve to explore. METHOD: A Half Thresholding Pursuit Algorithm (HTPA) combined with parameter optimization is proposed in this paper to efficiently solve the non-convex optimization model. Specifically, the half thresholding iteration method is utilized to solve -norm model, pursuit strategy is used to accelerate the process of iteration, and the parameter optimization scheme is designed to obtain robust parameter. RESULTS: Analysis and assessment on simulated and experimental data demonstrate that the proposed HTPA performs better in location accuracy and reconstructed fluorescent yield in less time cost, compared with the state-of-the-art reconstruction algorithms. CONCLUSION: The proposed HTPA combined with the parameter optimization scheme is an efficient and robust reconstruction approach to FMT. PMID- 30296210 TI - Estimating Missing Data in Temporal Data Streams Using Multi-directional Recurrent Neural Networks. AB - OBJECTIVE: Missing data is a ubiquitous problem. It is especially challenging in medical settings because many streams of measurements are collected at different and often irregular - times. Accurate estimation of those missing measurements is critical for many reasons, including diagnosis, prognosis and treatment. Existing methods address this estimation problem by interpolating within data streams or imputing across data streams (both of which ignore important information) or ignoring the temporal aspect of the data and imposing strong assumptions about the nature of the data-generating process and/or the pattern of missing data (both of which are especially problematic for medical data). We propose a new approach, based on a novel deep learning architecture that we call a Multi-directional Recurrent Neural Network (M-RNN) that interpolates within data streams and imputes across data streams. We demonstrate the power of our approach by applying it to five real-world medical datasets. We show that it provides dramatically improved estimation of missing measurements in comparison to 11 state-of-the-art benchmarks (including Spline and Cubic Interpolations, MICE, MissForest, matrix completion and several RNN methods); typical improvements in Root Mean Square Error are between 35% - 50%. Additional experiments based on the same five datasets demonstrate that the improvements provided by our method are extremely robust. PMID- 30296211 TI - A Patient-specific Approach for Short-term Epileptic Seizures Prediction through the Analysis of EEG synchronization. AB - Epilepsy is a neurological disorder arising from anomalies of the electrical activity in the brain, affecting about 65 millions individuals worldwide. {Objective:} This work proposes a patient-specific approach for short-term prediction (i.e., within few minutes) of epileptic seizures. {Methods:} We use noninvasive EEG data, since the aim is exploring the possibility of developing a noninvasive monitoring/control device for the prediction of seizures. Our approach is based on finding synchronization patterns in the EEG that allow to distinguish in real time preictal from interictal states. In practice, we develop easily computable functions over a graph model to capture the variations in the synchronization, and employ a classifier for identifying the preictal state. {Results:} We compare two state-of-the-art classification algorithms and a simple and computationally inexpensive threshold-based classifier developed ad hoc. Results on publicly available scalp EEG database and on data of the patients of the Unit of Neurology and Neurophysiology at University of Siena show that this simple and computationally viable processing is able to highlight the changes in synchronization when a seizure is approaching. {Conclusion and significance:} The proposed approach, characterized by low computational requirements and by the use of noninvasive techniques, is a step toward the development of portable and wearable devices for real-life use. PMID- 30296212 TI - Learning Compact Features for Human Activity Recognition via Probabilistic First Take-All. AB - With the popularity of mobile technology, wearable devices, such as smart wristbands and smartphones, open a unprecedented opportunity to solve the challenging human activity recognition (HAR) problem by learning expressive representations from the multi-dimensional sensor signals that record huge amounts of daily activities. This inspires us to develop a new algorithm applicable to both camera-based and wearable sensor-based HAR systems. Although competitive classification accuracy has been reported, existing methods often face the challenge of distinguishing visually similar activities composed of activity patterns in different temporal orders. In this paper, we propose a novel probabilistic algorithm to compactly encode temporal orders of activity patterns for HAR. Specifically, the algorithm learns an optimal set of latent patterns such that their temporal structures really matter in recognizing different human activities. Then a novel probabilistic First-Take-All (pFTA) approach is introduced to generate compact features from the orders of these latent patterns to encode an entire sequence, and the temporal structural similarity between different sequences can be efficiently computed by the Hamming distance between compact features. Experiments on three public HAR datasets show the proposed pFTA approach can achieve competitive performance in terms of accuracy as well as efficiency. PMID- 30296213 TI - Shallowing Deep Networks: Layer-wise Pruning based on Feature Representations. AB - Recent surge of Convolutional Neural Networks (CNNs) has brought successes among various applications. However, these successes are accompanied by a significant increase in computational cost and the demand for computational resources, which critically hampers the utilization of complex CNNs on devices with limited computational power. In this work, we propose a feature representation based layer-wise pruning method that aims at reducing complex CNNs to more compact ones with equivalent performance. Different from previous parameter pruning methods that conduct connection-wise or filter-wise pruning based on weight information, our method determines redundant parameters by investigating the features learned in the convolutional layers and the pruning process is operated at a layer level. Experiments demonstrate that the proposed method is able to significantly reduce computational cost and the pruned models achieve equivalent or even better performance compared to the original models on various datasets. PMID- 30296214 TI - Learning compact q-space representations for multi-shell diffusion-weighted MRI. AB - Diffusion-weighted MRI measures the direction and scale of the local diffusion process in every voxel through its spectrum in q-space, typically acquired in one or more shells. Recent developments in microstructure imaging and multi-tissue decomposition have sparked renewed attention in the radial b-value dependence of the signal. Applications in motion correction and outlier rejection therefore require a compact linear signal representation that extends over the radial as well as angular domain. Here, we introduce SHARD, a data-driven representation of the q-space signal based on spherical harmonics and a radial decomposition into orthonormal components. This representation provides a complete, orthogonal signal basis, tailored to the spherical geometry of q-space and calibrated to the data at hand. We demonstrate that the rank-reduced decomposition outperforms model-based alternatives in human brain data, whilst faithfully capturing the micro-and meso-structural information in the signal. Furthermore, we validate the potential of joint radial-spherical as compared to single-shell representations. As such, SHARD is optimally suited for applications that require low-rank signal predictions, such as motion correction and outlier rejection. Finally, we illustrate its application for the latter using outlier robust regression. PMID- 30296215 TI - Three-Dimensional Quantification of Filopodia in Motile Cancer Cells. AB - We present a three-dimensional bioimage analysis workflow to quantitatively analyze single, actin-stained cells with filopodial protrusions of diverse structural and temporal attributes, such as number, length, thickness, level of branching, and lifetime, in time-lapse confocal microscopy image data. Our workflow makes use of convolutional neural networks trained using real as well as synthetic image data, to segment the cell volumes with highly heterogeneous fluorescence intensity levels and to detect individual filopodial protrusions, followed by a constrained nearest-neighbor tracking algorithm to obtain valuable information about the spatio-temporal evolution of individual filopodia. We validated the workflow using real and synthetic 3D time-lapse sequences of lung adenocarcinoma cells of three morphologically distinct filopodial phenotypes and show that it achieves reliable segmentation and tracking performance, providing a robust, reproducible and less time-consuming alternative to manual analysis of the 3D+t image data. PMID- 30296216 TI - Separating Touching Cells using Pixel Replicated Elliptical Shape Models. AB - One of the most important and error-prone tasks in biological image analysis is the segmentation of touching or overlapping cells. Particularly for optical microscopy, including transmitted light and confocal fluorescence microscopy, there is often no consistent discriminative information to separate cells that touch or overlap. It is desired to partition touching foreground pixels into cells using the binary threshold image information only, and optionally incorporating gradient information. The most common approaches for segmenting touching and overlapping cells in these scenarios are based on the watershed transform. We describe a new approach called pixel replication for the task of segmenting elliptical objects that touch or overlap. Pixel replication uses the image Euclidean distance transform in combination with Gaussian mixture models to better exploit practically effective optimization for delineating objects with elliptical decision boundaries. Pixel replication improves significantly on commonly used methods based on watershed transforms, or based on fitting Gaussian mixtures directly to the thresholded image data. Pixel replication works equivalently on both 2-D and 3-D image data, and naturally combines information from multichannel images. The accuracy of the proposed technique is measured using both the segmentation accuracy on simulated ellipse data and the tracking accuracy on validated stem cell tracking results extracted from hundreds of live cell microscopy image sequences. Pixel replication is shown to be significantly more accurate compared to other approaches. Variance relationships are derived, allowing a more practically effective Gaussian mixture model to extract cell boundaries for data generated from the threshold image using the uniform elliptical distribution and from the distance transform image using the triangular elliptical distribution. PMID- 30296217 TI - Local Phase Velocity Based Imaging (LPVI): A New Technique Used For Ultrasound Shear Wave Elastography. AB - Ultrasound shear wave elastography is an imaging modality for noninvasive evaluation of tissue mechanical properties. However, many current techniques overestimate lesions dimension or shape especially when small inclusions are taken into account. In this study we propose a new method called local phase velocity based imaging (LPVI) as an alternative technique to measure tissue elasticity. Two separate acquisitions with ultrasound push beams focused once on the left side and once on the right side of the inclusion were generated. A local shear wave velocity is then recovered in the frequency domain (for a single frequency or frequency band) for both acquired data sets. Finally, a two dimensional shear wave velocity map is reconstructed by combining maps from two separate acquisitions. Robust and accurate shear wave velocity maps are reconstructed using the proposed LPVI method in calibrated liver fibrosis tissue mimicking homogeneous phantoms, a calibrated elastography phantom with stepped cylinder inclusions and a homemade gelatin phantom with ex vivo porcine liver inclusion. Results are compared with an existing phase velocity based imaging approach and a group velocity based method considered as the state-of-the-art. Results from the phantom study showed that increased frequency improved the shape of the reconstructed inclusions and contrast-to-noise ratio between the target and background. PMID- 30296218 TI - Fully-differential Piezoelectric Button-like Mode Disk Resonator for Liquid Phase Sensing. AB - We present a unique lateral shear resonance mode excited in a micro-electro mechanical (MEM) disk resonator. We refer to this proposed mode as the Button like (BL) mode. The BL mode has a characteristic lateral strain profile (based on the sum of orthogonal strain components in the plane of fabrication) resembles a shirt button. Hence our choice of name for this mode. The strain profile of the BL mode is highly suited for piezoelectric transduction. Like the more widely reported Wine Glass (WG) or elliptical mode, the BL mode offers feedthrough cancellation through fully-differential transduction. But compared to the WG mode, the BL mode possesses higher coupling coefficient (keff2) and higher quality (Q) factor for the same disk radius. These advantages make the BL mode highly-attractive for realizing electrically-addressed MEM resonators for liquid phase sensing. This paper examines various design aspects pertaining to the BL mode: tether geometry, characterization setup, size of disk, and even the effect of the gap around the disk on Q factor. The highest Q factor measured in water is 410 based on a disk with a radius of 150 MUm. The lowest motional resistance in water is 1.36 kOmega based on a disk with a radius of 400 MUm. PMID- 30296219 TI - Dictionary Representations for Electrode Displacement Elastography. AB - Ultrasound electrode displacement elastography (EDE) has demonstrated the potential to monitor ablated regions in human patients after minimally invasive microwave ablation procedures. Displacement estimation for EDE is commonly plagued by decorrelation noise artifacts degrading displacement estimates. In this paper we propose a global dictionary learning approach applied to denoising displacement estimates with an adaptively learned dictionary from EDE phantom displacement maps. The resulting algorithm is one that represents displacement patches sparsely if they contain low noise and averages remaining patches thereby denoising displacement maps while retaining important edge information. Results of dictionary represented displacements presented with higher signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) with improved contrast, as well as improved phantom inclusion delineation when compared to initial displacements, median filtered displacements, and spline smoothened displacements respectively. In addition to visualized noise reduction, dictionary represented displacements presented with the highest SNR, CNR and improved contrast with values of 1.77 dB, 4.56 dB, and 4.35 dB when compared to axial strain tensor images estimated using the initial displacements. Following EDE phantom imaging, we utilized dictionary representations from in-vivo patient data, further validating efficacy. Denoising displacement estimates is a newer application for dictionary learning producing strong ablated region delineation with little degradation from denoising. PMID- 30296220 TI - Sparse Convolutional Beamforming for Ultrasound Imaging. AB - The standard technique used by commercial medical ultrasound systems to form B mode images is delay and sum (DAS) beamforming. However, DAS often results in limited image resolution and contrast, which are governed by the center frequency and the aperture size of the ultrasound transducer. A large number of elements leads to improved resolution but at the same time increases the data size and the system cost due to the receive electronics required for each element. Therefore, reducing the number of receiving channels while producing high quality images is of great importance. In this paper, we introduce a nonlinear beamformer called COnvolutional Beamforming Algorithm (COBA), which achieves significant improvement of lateral resolution and contrast. In addition, it can be implemented efficiently using the fast Fourier transform. Based on the COBA concept, we next present two sparse beamformers with closed form expressions for the sensor locations, which result in the same beam pattern as DAS and COBA while using far fewer array elements. Optimization of the number of elements shows that they require a minimal number of elements which is on the order of the square root of the number used by DAS. The performance of the proposed methods is tested and validated using simulated data, phantom scans and in vivo cardiac data. The results demonstrate that COBA outperforms DAS in terms of resolution and contrast and that the suggested beamformers offer a sizable element reduction while generating images with an equivalent or improved quality in comparison to DAS. PMID- 30296221 TI - Broadband 1-3 Piezoelectric Composite Transducer Design using Sierpinski Gasket Fractal Geometry. AB - Wider operational bandwidth is an important requirement of an ultrasound transducer across many applications. In nature, it can be observed that several hearing organs possess a broad operating bandwidth by having a varying length scales structure. Moreover, conventional 1-3 piezoelectric composite transducers have been widely recognized for their wider bandwidth over their piezoelectric ceramic counterparts. In this paper, a novel 1-3 piezoelectric composite design using a fractal geometry, known as the Sierpinski Gasket (SG), is proposed in order to explore the potential of further extending the operational bandwidth and sensitivity of the transducer. Two equivalent 1-3 piezocomposite designs are compared to this end, one with a conventional periodic parallelepiped shaped pillar structure and one with the SG fractal geometry, both theoretically, using a finite element (FE) analysis package, and experimentally. The transmit voltage response and open circuit voltage response are used to illustrate bandwidth improvement from the fractal composite design. Following the simulation results, a 580 kHz single element transducer, utilizing the proposed SG fractal microstructure, is fabricated using a pillar placement methodology. The performance of the prototyped device is characterized and compared with a conventional 1-3 composite design, as well as with a commercial ultrasound transducer. In the one-way transmission mode, a bandwidth improvement of 27.2 % and sensitivity enhancement of 3.8 dB can be found with the SG fractal design compared to an equivalent conventional composite design and up 105.1 % bandwidth improvement when compared to the commercial transducer. In the one-way reception mode, the bandwidth improvement for the SG fractal design is 2.5 % and 32.9 % when compared to the conventional and commercial transducers, respectively. PMID- 30296222 TI - Cs Fountain Clocks for Commercial Realisations - an Improved and Robust Design. AB - We report on the design, assembly, testing and delivery of a series of new caesium fountain primary frequency standards built through commercial and scientific collaboration with international users. The new design, based on proven NPL solutions, improves reliability, simplicity of operation and transportability. The complete system consists of a novel physics package, a specially developed optical package and dedicated electronics for system control. We present results showing that despite their simplified and more compact design, the new fountains have state-of-the-art performance in terms of signal-to-noise ratio and robust long-term operation. With a sufficiently low noise local oscillator they are capable of reaching a short-term stability below 3*10-14 (1 s) and have potential accuracy in the low 10-16 range, similar to the best caesium fountains currently in operation. This cost-effective solution could be used to increase the availability of accurate frequency references and timescales and provide redundancy in critical locations. PMID- 30296223 TI - Hierarchical Contextual Refinement Networks for Human Pose Estimation. AB - Predicting human pose in the wild is a challenging problem due to high flexibility of joints and possible occlusion. Existing approaches generally tackle the difficulties either by holistic prediction or multi-stage processing, which suffer from poor performance for locating challenging joints or high computational cost. In this paper, we propose a new Hierarchical Contextual Refinement Network (HCRN) to robustly predict human poses in an efficient manner, where human body joints of different complexities are processed at different layers in a context hierarchy. Different from existing approaches, our proposed model predicts positions of joints from easy to difficult in a single stage through effectively exploiting informative contexts provided in the previous layer. Such approach offers two appealing advantages over state-of-the-arts: (1) more accurate than predicting all the joints together and (2) more efficient than multi-stage processing methods. We design a Contextual Refinement Unit (CRU) to implement the proposed model, which enables auto-diffusion of joint detection results to effectively transfer informative context from easy joints to difficult ones. In this way, difficult joints can be reliably detected even in presence of occlusion or severe distracting factors. Multiple CRUs are organized into a tree structured hierarchy which is end-to-end trainable and does not require processing joints for multiple iterations. Comprehensive experiments evaluate the efficacy and efficiency of the proposed HCRN model to improve well-established baselines and achieve new state-of-the-art on multiple human pose estimation benchmarks. PMID- 30296224 TI - Joint Tumor Segmentation in PET-CT Images Using Co-Clustering and Fusion Based on Belief Functions. AB - Precise delineation of target tumor is a key factor to ensure the effectiveness of radiation therapy. While hybrid positron emission tomography-computed tomography (PET-CT) has become a standard imaging tool in the practice of radiation oncology, many existing automatic/semi-automatic methods still perform tumor segmentation on mono-modal images. In this paper, a co-clustering algorithm is proposed to concurrently segment 3D tumors in PET-CT images, considering that the two complementary imaging modalities can combine functional and anatomical information to improve segmentation performance. The theory of belief functions is adopted in the proposed method to model, fuse, and reason with uncertain and imprecise knowledge from noisy and blurry PET-CT images. To ensure reliable segmentation for each modality, the distance metric for the quantification of clustering distortions and spatial smoothness is iteratively adapted during the clustering procedure. On the other hand, to encourage consistent segmentation between different modalities, a specific context term is proposed in the clustering objective function. Moreover, during the iterative optimization process, clustering results for the two distinct modalities are further adjusted via a belief-functions-based information fusion strategy. The proposed method has been evaluated on a data set consisting of 21 paired PET-CT images for non-small cell lung cancer patients. The quantitative and qualitative evaluations show that our proposed method performs well compared with the state-of-the-art methods. PMID- 30296225 TI - Deep Crisp Boundaries: From Boundaries to Higher-Level Tasks. AB - Edge detection has made significant progress with the help of deep convolutional networks (ConvNet). These ConvNet-based edge detectors have approached human level performance on standard benchmarks. We provide a systematical study of these detectors' outputs. We show that the detection results did not accurately localize edge pixels, which can be adversarial for tasks that require crisp edge inputs. As a remedy, we propose a novel refinement architecture to address the challenging problem of learning a crisp edge detector using ConvNet. Our method leverages a top-down backward refinement pathway, and progressively increases the resolution of feature maps to generate crisp edges. Our results achieve superior performance, surpassing human accuracy when using standard criteria on BSDS500, and largely outperforming the state-of-the-art methods when using more strict criteria. More importantly, we demonstrate the benefit of crisp edge maps for several important applications in computer vision, including optical flow estimation, object proposal generation, and semantic segmentation. PMID- 30296226 TI - Minimal Paths for Tubular Structure Segmentation With Coherence Penalty and Adaptive Anisotropy. AB - The minimal path method has proven to be particularly useful and efficient in tubular structure segmentation applications. In this paper, we propose a new minimal path model associated with a dynamic Riemannian metric embedded with an appearance feature coherence penalty and an adaptive anisotropy enhancement term. The features that characterize the appearance and anisotropy properties of a tubular structure are extracted through the associated orientation score. The proposed the dynamic Riemannian metric is updated in the course of the geodesic distance computation carried out by the efficient single-pass fast marching method. Compared to the state-of-the-art minimal path models, the proposed minimal path model is able to extract the desired tubular structures from a complicated vessel tree structure. In addition, we propose an efficient prior path-based method to search for vessel radius value at each centerline position of the target. Finally, we perform the numerical experiments on both synthetic and real images. The quantitive validation is carried out on retinal vessel images. The results indicate that the proposed model indeed achieves a promising performance. PMID- 30296227 TI - Fine-Grained Quality Assessment for Compressed Images. AB - Image quality assessment (IQA) has attracted more and more attention due to the urgent demand in image services. The perceptual-based image compression is one of the most prominent applications that require IQA metrics to be highly correlated with human vision. To explore IQA algorithms that are more consistent with human vision, several calibrated databases have been constructed. However, the distorted images in the existing databases are usually generated by corrupting the pristine images with various distortions in coarse levels, such that the IQA algorithms validated on them may be inefficient to optimize the perceptual-based image compression with fine-grained quality differences. In this paper, we construct a large-scale image database which can be used for fine-grained quality assessment of compressed images. In the proposed database, reference images are compressed at constant bitrate levels by JPEG encoders with different optimization methods. To distinguish subtle differences, the pair-wise comparison method is utilized to rank them in subjective experiments. We select 100 reference images for the proposed database, and each image is compressed into three target bitrates by four different JPEG optimization methods, such that 1200 distorted images are generated in total. Sixteen well-known IQA algorithms are evaluated and analyzed on the proposed database. With the devised fine-grained IQA database, we expect to further promote image quality assessment by shifting it from a coarse-grained stage to a fine-grained stage. The database is available at: https://sites.google.com/site/zhangxinf07/fg-iqa. PMID- 30296228 TI - High-quality Image Restoration Using Low-Rank Patch Regularization and Global Structure Sparsity. AB - In recent years, approaches based on nonlocal self similarity and global structure regularization have led to significant improvements in image restoration. Nonlocal self similarity exploits the repetitiveness of small image patches as a powerful prior in the reconstruction process. Likewise, global structure regularization is based on the principle that the structure of objects in the image is represented by a relatively small portion of pixels. Enforcing this structural information to be sparse can thus reduce the occurrence of reconstruction artifacts. So far, most image restoration approaches have considered one of these two strategies, but not both. This paper presents a novel image restoration method that combines nonlocal self similarity and global structure sparsity in a single efficient model. Group of similar patches are reconstructed simultaneously, via an adaptive regularization technique based on the weighted nuclear norm. Moreover, global structure is preserved using an innovative strategy, which decomposes the image into a smooth component and a sparse residual, the latter regularized using l1 norm. An optimization technique, based on the Alternating Direction Method of Multipliers (ADMM) algorithm, is used to recover corrupted images efficiently. The performance of the proposed method is evaluated on two important image restoration tasks: image completion and super-resolution. Experimental results show our method to outperform state-of the-art approaches for these tasks, for various types and levels of image corruption.

In this paper, we introduce a novel deep color guided coarse-to-fine convolutional neural network (CNN) framework to address this problem. First, we present a datadriven filter method to approximate the ideal filter for depth image super-resolution instead of hand-designed filters. Based on large data samples, the filter learned is more accurate and stable for upsampling depth image. Second, we introduce a coarse-to-fine CNN to learn different sizes of filter kernels. In coarse stage, larger filter kernels are learned by CNN to achieve crude high-resolution depth image. As to fine stage, the crude high-resolution depth image is used as the input so that smaller filter kernels are learned to gain more accurate results. Benefit from this network, we can progressively recover the high frequency details. Third, we construct a color guidance strategy that fuses color difference and spatial distance for depth image upsampling. We revise the interpolated high-resolution depth image according to the corresponding pixels in highresolution color maps. Guided by color information, the depth of high resolution image obtained can alleviate texture copying artifacts and preserve edge details effectively. Quantitative and qualitative experimental results demonstrate our state-of-the-art performance for depth map super-resolution. PMID- 30296230 TI - Unifying Sum and Weighted Aggregations for Efficient yet Effective Image Representation Computation. AB - Embedding and aggregating a set of local descriptors (e.g. SIFT) into a single vector is normally used to represent images in image search. Standard aggregation operations include sum and weighted aggregations. While showing high efficiency, sum aggregation lacks discriminative power. In contrast, weighted aggregation shows promising retrieval performance but suffers extremely high time cost. In this work, we present a general mixed aggregation method that unifies sum and weighted aggregation methods. Owing to its general formulation, our method is able to balance the trade-off between retrieval quality and image representation efficiency. Additionally, to improve query performance, we propose computing multiple weighting coefficients rather than one for each to be aggregated vector by partitioning them into several components with negligible computational cost. Extensive experimental results on standard public image retrieval benchmarks demonstrate that our aggregation method achieves state-of-the-art performance while showing over ten times speedup over baselines. PMID- 30296231 TI - Moving Object Detection in Complex Scene Using Spatiotemporal Structured-Sparse RPCA. AB - Moving object detection is a fundamental step in various computer vision applications. Robust Principal Component Analysis (RPCA) based methods have often been employed for this task. However, the performance of these methods deteriorates in the presence of dynamic background scenes, camera jitter, camouflaged moving objects, and/or variations in illumination. It is because of an underlying assumption that the elements in the sparse component are mutually independent, and thus the spatiotemporal structure of the moving objects is lost. To address this issue, we propose a spatiotemporal structured sparse RPCA algorithm for moving objects detection, where we impose spatial and temporal regularization on the sparse component in the form of graph Laplacians. Each Laplacian corresponds to a multi-feature graph constructed over superpixels in the input matrix. We enforce the sparse component to act as eigenvectors of the spatial and temporal graph Laplacians while minimizing the RPCA objective function. These constraints incorporate a spatiotemporal subspace structure within the sparse component. Thus, we obtain a novel objective function for separating moving objects in the presence of complex backgrounds. The proposed objective function is solved using a linearized alternating direction method of multipliers based batch optimization. Moreover, we also propose an online optimization algorithm for real-time applications. We evaluated both the batch and online solutions using six publicly available datasets that included most of the aforementioned challenges. Our experiments demonstrated the superior performance of the proposed algorithms compared with the current state-of-the-art methods. PMID- 30296232 TI - Blind deblurring of natural stochastic textures using an anisotropic fractal model and phase retrieval algorithm. AB - The challenging inverse problem of blind deblurring has been investigated thoroughly for natural images. Existing algorithms exploit edge-type structures, or similarity to smaller patches within the image, to estimate the correct blurring kernel. However, these methods do not perform well enough on natural stochastic textures (NST), which are mostly random and in general are not characterized by distinct edges and contours. In NST even small kernels cause severe degradation to images. Restoration poses therefore an outstanding challenge. In this work, we refine an existing method by implementing an anisotropic fractal model to estimate the blur kernel's power spectral density. The final kernel is then estimated via an adaptation of a phase retrieval algorithm, originally proposed for sparse signals. We further incorporate additional constraints that are specific to blur filters, to yield even better results. The latter are compared with results obtained by recently published blind deblurring methods. PMID- 30296233 TI - CamStyle: A Novel Data Augmentation Method for Person Re-Identification. AB - Person re-identification (re-ID) is a cross-camera retrieval task that suffers from image style variations caused by different cameras. The art implicitly addresses this problem by learning a camera-invariant descriptor subspace. In this paper, we explicitly consider this challenge by introducing camera style (CamStyle). CamStyle can serve as a data augmentation approach that reduces the risk of deep network overfitting and that smooths the CamStyle disparities. Specifically, with a style transfer model, labeled training images can be style transferred to each camera, and along with the original training samples, form the augmented training set. This method, while increasing data diversity against overfitting, also incurs a considerable level of noise. In the effort to alleviate the impact of noise, the label smooth regularization (LSR) is adopted. The vanilla version of our method (without LSR) performs reasonably well on few camera systems in which overfitting often occurs. With LSR, we demonstrate consistent improvement in all systems regardless of the extent of overfitting. We also report competitive accuracy compared with the state of the art on Market 1501 and DukeMTMC-re-ID. Importantly, CamStyle can be employed to the challenging problems of one view learning and unsupervised domain adaptation (UDA) in person re-identification (re-ID), both of which have critical research and application significance. The former only has labeled data in one camera view and the latter only has labeled data in the source domain. Experimental results show that CamStyle significantly improves the performance of the baseline in the two problems. Specially, for UDA, CamStyle achieves state-of-the-art accuracy based on a baseline deep re-ID model on Market-1501 and DukeMTMC-reID. Our code is available at: https://github.com/zhunzhong07/CamStyle . PMID- 30296234 TI - Improving the Visual Quality of Size-Invariant Visual Cryptography for Grayscale Images: An Analysis-by-Synthesis (AbS) Approach. AB - In visual cryptography (VC) for grayscale image, size reduction leads to bad perceptual quality to the reconstructed secret image. To improve the quality, the current efforts are limited to the design of VC algorithm for binary image, and measuring the quality with metrics that are not directly related to how the human visual system (HVS) perceives halftone images. We propose an analysis-by synthesis (AbS) framework to integrate the halftoning process and the VC encoding: the secret pixel/block is reconstructed from the shares in the encoder and the error between the reconstructed secret and the original secret images is fed back and compensated concurrently by the error diffusion process. In doing so, the error between the reconstructed secret and original secret is pushed to high frequency band, thus producing visually pleasing reconstructed secret image. This framework is simple and flexible in that it can be combined with many existing size-invariant VC algorithms, including probabilistic VC, random grid VC and vector/block VC. More importantly, it is proved that this AbS framework is as secure as the traditional VC algorithms. Experimental results demonstrate the effectiveness of the proposed AbS framework. PMID- 30296235 TI - Multi-pseudo Regularized Label for Generated Data in Person Re-Identification. AB - Sufficient training data normally is required to train deeply learned models. However, due to the expensive manual process for labelling large number of images (i.e., annotation), the amount of available training data (i.e., real data) is always limited. To produce more data for training a deep network, Generative Adversarial Network (GAN) can be used to generate artificial sample data (i.e., generated data). However, the generated data usually does not have annotation labels. To solve this problem, in this paper, we propose a virtual label called Multi-pseudo Regularized Label (MpRL) and assign it to the generated data. With MpRL, the generated data will be used as the supplementary of real training data to train a deep neural network in a semi-supervised learning fashion. To build the corresponding relationship between the real data and generated data, MpRL assigns each generated data a proper virtual label which reflects the likelihood of the affiliation of the generated data to predefined training classes in the real data domain. Unlike the traditional label which usually is a single integral number, the virtual label proposed in this work is a set of weight-based values each individual of which is a number in (0,1] called multi-pseudo label and reflects the degree of relation between each generated data to every pre-defined class of real data. A comprehensive evaluation is carried out by adopting two state-of-the-art convolutional neural networks (CNNs) in our experiments to verify the effectiveness of MpRL. Experiments demonstrate that by assigning MpRL to generated data, we can further improve the person re-ID performance on five re ID datasets, i.e., Market-1501, DukeMTMC-reID, CUHK03, VIPeR, and CUHK01. The proposed method obtains +6.29%, +6.30%, +5.58%, +5.84%, and +3.48% improvements in rank-1 accuracy over a strong CNN baseline on the five datasets respectively, and outperforms state-of-the-art methods. PMID- 30296236 TI - Large-Scale Circuitry Interactions Upon Earthquake Experiences Revealed by Recurrent Neural Networks. AB - Brain dynamics has recently received increasing interest due to its significant importance in basic and clinical neurosciences. However, due to inherent difficulties in both data acquisition and data analysis methods, studies on large scale brain dynamics of mouse with local field potential (LFP) recording are very rare. In this paper, we did a series of works on modeling large-scale mouse brain dynamic activities responding to fearful earthquake. Based on LFP recording data from 13 brain regions that are closely related to fear learning and memory and the effective Bayesian connectivity change point model, we divided the response time series into four stages: "Before," "Earthquake," "Recovery," and "After." We first reported the changes in power and theta-gamma coupling during stage transitions. Then, a recurrent neural network model was designed to model the functional dynamics in these thirteen brain regions and six frequency bands in response to the fear stimulus. Interestingly, our results showed that the functional brain connectivities in theta and gamma bands exhibited distinct response processes: in theta band, there is a separated-united-separated alternation in whole-brain connectivity and a low-high-low change in connectivity strength; however, gamma bands have a united-separated-united transition and a high-low-high alternation in connectivity pattern and strength. In general, our results offer a novel perspective in studying functional brain dynamics under fearful stimulus and reveal its relationship to the brain's structural connectivity substrates. PMID- 30296237 TI - Kernel Generalized Likelihood Ratio Test for Fault Detection of Biological Systems. AB - In this paper, we develop an improved fault detection (FD) technique in order to enhance the monitoring abilities of nonlinear biological processes. Generalized likelihood ratio test (GLRT)-based kernel principal component analysis (KPCA) (called also kernel GLRT) is an effective data-driven technique for monitoring nonlinear processes. However, it is well known that the data collected from complex and multivariate processes are multiscale due to the variety of changes that could occur in process with different localization in time and frequency. Thus, to enhance the process monitoring abilities, we propose to combine the advantages of kernel GLRT and multiscale representation using wavelets by developing a multiscale kernel GLRT (MS-KGLRT) detection chart. The proposed fault detection approach is addressed so that the KPCA is used to compute the model in the feature space and the MS-KGLRT chart is applied to detect the faults. The detection performance of the new chart is studied using two examples, one using synthetic data and the other using biological process representing a Cad System in E. Coli (CSEC) model for detecting small and moderate shifts (offset or bias and drift). The MS-KGLRT chart is used to enhance fault detection of the CSEC model through monitoring some of the key variables involved in this model such as enzymes, lysine, and cadaverine. PMID- 30296238 TI - Term-based Personalization for Feature Selection in Clinical Handover Form Auto filling. AB - Feature learning and selection have been widely applied in many research areas because of their good performance and lower complexity. Traditional methods usually treat all terms with same feature sets, such that performance can be damaged when noisy information is brought by wrong features for a given term. In this paper, we propose a term-based personalization approach to finding the best features for each term. First, features are given as the input so that we focus on selection strategies. Second, we present a feature searching method to generate feature candidate subsets for each term. After that, the importance of each candidate feature subset to a given term is evaluated by the term-feature probabilistic relevance model. Finally, we obtain the personalized feature set for each term as a subset of all features. Experiments have been conducted on the NICTA Synthetic Nursing Handover dataset and the results show that our approach is promising and effective. PMID- 30296239 TI - Identifying Key Genes of Liver Cancer by Networking of Multiple Data Sets. AB - Liver cancer is one of the deadliest cancers in the world. To find effective therapies for this cancer, it is indispensable to identify key genes, which may play critical roles in the incidence of the liver cancer. To identify key genes of the liver cancer with high accuracy, we integrated multiple microarray gene expression data sets to compute common differentially expressed genes, which will result more accurate than those from individual data set. To find the main functions or pathways that these genes are involved in, some enrichment analyses were performed including functional enrichment analysis, pathway enrichment analysis, and disease association study. Based on these genes, a protein-protein interaction network was constructed and analyzed to identify key genes of the liver cancer by combining the local and global influence of nodes in the network. The identified key genes, such as TOP2A, ESR1, and KMO, have been demonstrated to be key biomarkers of the liver cancer in many publications. All the results suggest that our method can effectively identify key genes of the liver cancer. Moreover, our method can be applied to other types of data sets to select key genes of other complex diseases. PMID- 30296240 TI - Combining High Speed ELM Learning with a Deep Convolutional Neural Network Feature Encoding for Predicting Protein-RNA Interactions. AB - Emerging evidence has shown that RNA plays a crucial role in many cellular processes, and their biological functions are primarily achieved by binding with a variety of proteins. High-throughput biological experiments provide a lot of valuable information for the initial identification of RNA-protein interactions (RPIs), but with the increasing complexity of RPIs networks, this method gradually falls into expensive and time-consuming situations. Therefore, there is an urgent need for high speed and reliable methods to predict RNA-protein interactions. In this study, we propose a computational method for predicting the RNA-protein interactions using sequence information. The deep learning convolution neural network (CNN) algorithm is utilized to mine the hidden high level discriminative features from the RNA and protein sequences and feed it into the extreme learning machine (ELM) classifier. The experimental results with 5 fold cross-validation indicate that the proposed method achieves superior performance on benchmark datasets (RPI1807, RPI2241 and RPI369) with the accuracy of 98.83%, 90.83% and 85.63%, respectively. We further evaluate the performance of the proposed model by comparing it with the state-of-the-art SVM classifier and other existing methods on the same benchmark data set. The experimental results show our model can serve as a useful tool for predicting RNA-protein interactions. PMID- 30296241 TI - Approximate Optimal Distributed Control of Nonlinear Interconnected Systems Using Event-Triggered Nonzero-Sum Games. AB - In this paper, approximate optimal distributed control schemes for a class of nonlinear interconnected systems with strong interconnections are presented using continuous and event-sampled feedback information. The optimal control design is formulated as an $N$-player nonzero-sum game where the control policies of the subsystems act as players. An approximate Nash equilibrium solution to the game, which is the solution to the coupled Hamilton-Jacobi equation, is obtained using the approximate dynamic programming-based approach. A critic neural network (NN) at each subsystem is utilized to approximate the Nash solution and novel event sampling conditions, that are decentralized, are designed to asynchronously orchestrate the sampling and transmission of state vector at each subsystem. To ensure the local ultimate boundedness of the closed-loop system state and NN parameter estimation errors, a hybrid-learning scheme is introduced and the stability is guaranteed using Lyapunov-based stability analysis. Finally, implementation of the proposed event-based distributed control scheme for linear interconnected systems is discussed. For completeness, Zeno-free behavior of the event-sampled system is shown analytically and a numerical example is included to support the analytical results. PMID- 30296242 TI - Output Feedback Q-Learning Control for the Discrete-Time Linear Quadratic Regulator Problem. AB - Approximate dynamic programming (ADP) and reinforcement learning (RL) have emerged as important tools in the design of optimal and adaptive control systems. Most of the existing RL and ADP methods make use of full-state feedback, a requirement that is often difficult to satisfy in practical applications. As a result, output feedback methods are more desirable as they relax this requirement. In this paper, we present a new output feedback-based Q-learning approach to solving the linear quadratic regulation (LQR) control problem for discrete-time systems. The proposed scheme is completely online in nature and works without requiring the system dynamics information. More specifically, a new representation of the LQR Q-function is developed in terms of the input-output data. Based on this new Q-function representation, output feedback LQR controllers are designed. We present two output feedback iterative Q-learning algorithms based on the policy iteration and the value iteration methods. This scheme has the advantage that it does not incur any excitation noise bias, and therefore, the need of using discounted cost functions is circumvented, which in turn ensures closed-loop stability. It is shown that the proposed algorithms converge to the solution of the LQR Riccati equation. A comprehensive simulation study is carried out, which illustrates the proposed scheme. PMID- 30296243 TI - Multistability of Delayed Hybrid Impulsive Neural Networks With Application to Associative Memories. AB - The important topic of multistability of continuous- and discrete-time neural network (NN) models has been investigated rather extensively. Concerning the design of associative memories, multistability of delayed hybrid NNs is studied in this paper with an emphasis on the impulse effects. Arising from the spiking phenomenon in biological networks, impulsive NNs provide an efficient model for synaptic interconnections among neurons. Using state-space decomposition, the coexistence of multiple equilibria of hybrid impulsive NNs is analyzed. Multistability criteria are then established regrading delayed hybrid impulsive neurodynamics, for which both the impulse effects on the convergence rate and the basins of attraction of the equilibria are discussed. Illustrative examples are given to verify the theoretical results and demonstrate an application to the design of associative memories. It is shown by an experimental example that delayed hybrid impulsive NNs have the advantages of high storage capacity and high fault tolerance when used for associative memories. PMID- 30296245 TI - Learning Latent Stable Patterns for Image Understanding With Weak and Noisy Labels. AB - This paper focuses on weakly supervised image understanding, in which the semantic labels are available only at image-level, without the specific object or scene location in an image. Existing algorithms implicitly assume that image level labels are error-free, which might be too restrictive. In practice, image labels obtained from the pretrained predictors are easily contaminated. To solve this problem, we propose a novel algorithm for weakly supervised segmentation when only noisy image labels are available during training. More specifically, a semantic space is constructed first by encoding image labels through a graphlet (i.e., superpixel cluster) embedding process. Then, we observe that in the semantic space, the distribution of graphlets from images with a same label remains stable, regardless of the noises in image labels. Therefore, we propose a generative model, called latent stability analysis, to discover the stable patterns from images with noisy labels. Inferring graphlet semantics by making use of these mid-level stable patterns is much more secure and accurate than directly transferring noisy image-level labels into different regions. Finally, we calculate the semantics of each superpixel using maximum majority voting of its correlated graphlets. Comprehensive experimental results show that our algorithm performs impressively when the image labels are predicted by either the hand-crafted or deeply learned image descriptors. PMID- 30296244 TI - Mining directional drug interaction effects on myopathy using the FAERS database. AB - Mining high-order drug-drug interaction (DDI) induced adverse drug effects from electronic health record (EHR) databases is an emerging area, and very few studies have explored the relationships between high-order drug combinations. We investigate a novel pharmacovigilance problem for mining directional DDI effects on myopathy using the FDA Adverse Event Reporting System (FAERS) database. Our work provides information on the risk of myopathy associated with adding new drugs on the already prescribed medication, and visualizes the identified directional DDI patterns as user-friendly graphical representation. We utilize the Apriori algorithm to extract frequent drug combinations from the FAERS database. We use odds ratio (OR) to estimate the risk of myopathy associated with directional DDI. We create a tree-structured graph to visualize the findings for easy interpretation. Our method confirmed myopathy association with previously reported HMG-CoA reductase inhibitors like rosuvastatin, fluvastatin, simvastatin and atorvastatin. New, previously unidentified but mechanistically plausible associations with myopathy were also observed, such as the DDI between pamidronate and levofloxacin. Additional top findings are gadolinium-based imaging agents, which however are often used in myopathy diagnosis. Other DDIs with no obvious mechanism are also reported, such as that of sulfamethoxazole with trimethoprim and potassium chloride. This study shows the feasibility to estimate high-order directional DDIs in a fast and accurate manner. The results of the analysis could become a useful tool in the specialists' hands through an easy-to-understand graphic visualization. PMID- 30296246 TI - A Directionally Selective Small Target Motion Detecting Visual Neural Network in Cluttered Backgrounds. AB - Discriminating targets moving against a cluttered background is a huge challenge, let alone detecting a target as small as one or a few pixels and tracking it in flight. In the insect's visual system, a class of specific neurons, called small target motion detectors (STMDs), have been identified as showing exquisite selectivity for small target motion. Some of the STMDs have also demonstrated direction selectivity which means these STMDs respond strongly only to their preferred motion direction. Direction selectivity is an important property of these STMD neurons which could contribute to tracking small targets such as mates in flight. However, little has been done on systematically modeling these directionally selective STMD neurons. In this paper, we propose a directionally selective STMD-based neural network for small target detection in a cluttered background. In the proposed neural network, a new correlation mechanism is introduced for direction selectivity via correlating signals relayed from two pixels. Then, a lateral inhibition mechanism is implemented on the spatial field for size selectivity of the STMD neurons. Finally, a population vector algorithm is used to encode motion direction of small targets. Extensive experiments showed that the proposed neural network not only is in accord with current biological findings, i.e., showing directional preferences but also worked reliably in detecting the small targets against cluttered backgrounds. PMID- 30296247 TI - e-RNSP: An Efficient Method for Mining Repetition Negative Sequential Patterns. AB - Negative sequential patterns (NSPs), which capture both frequent occurring and nonoccurring behaviors, become increasingly important and sometimes play a role irreplaceable by analyzing occurring behaviors only. Repetition sequential patterns capture repetitions of patterns in different sequences as well as within a sequence and are very important to understand the repetition relations between behaviors. Though some methods are available for mining NSP and repetition positive sequential patterns (RPSPs), we have not found any methods for mining repetition NSP (RNSP). RNSP can help the analysts to further understand the repetition relationships between items and capture more comprehensive information with repetition properties. However, mining RNSP is much more difficult than mining NSP due to the intrinsic challenges of nonoccurring items. To address the above issues, we first propose a formal definition of repetition negative containment. Then, we propose a method to convert repetition negative containment to repetition positive containment, which fast calculates the repetition supports by only using the corresponding RPSP's information without rescanning databases. Finally, we propose an efficient algorithm, called e-RNSP, to mine RNSP efficiently. To the best of our knowledge, e-RNSP is the first algorithm to efficiently mine RNSP. Intensive experimental results on the first four real and synthetic datasets clearly show that e-RNSP can efficiently discover the repetition negative patterns; results on the fifth dataset prove the effectiveness of RNSP which are captured by the proposed method; and the results on the rest 16 datasets analyze the impacts of data characteristics on mining process. PMID- 30296248 TI - Objective-Domain Dual Decomposition: An Effective Approach to Optimizing Partially Differentiable Objective Functions. AB - This paper addresses a class of optimization problems in which either part of the objective function is differentiable while the rest is nondifferentiable or the objective function is differentiable in only part of the domain. Accordingly, we propose a dual-decomposition-based approach that includes both objective decomposition and domain decomposition. In the former, the original objective function is decomposed into several relatively simple subobjectives to isolate the nondifferentiable part of the objective function, and the problem is consequently formulated as a multiobjective optimization problem (MOP). In the latter decomposition, we decompose the domain into two subdomains, that is, the differentiable and nondifferentiable domains, to isolate the nondifferentiable domain of the nondifferentiable subobjective. Subsequently, the problem can be optimized with different schemes in the different subdomains. We propose a population-based optimization algorithm, called the simulated water-stream algorithm (SWA), for solving this MOP. The SWA is inspired by the natural phenomenon of water streams moving toward a basin, which is analogous to the process of searching for the minimal solutions of an optimization problem. The proposed SWA combines the deterministic search and heuristic search in a single framework. Experiments show that the SWA yields promising results compared with its existing counterparts. PMID- 30296249 TI - Multiobjective Rule-Based Cooperative Continuous Ant Colony Optimized Fuzzy Systems With a Robot Control Application. AB - This paper proposes a new rule-based cooperative framework for multiobjective evolutionary fuzzy systems (FSs). Based on the framework, a multiobjective rule based cooperative continuous ant-colony optimization (MO-RCCACO) algorithm is proposed to optimize all of the free parameters in FSs. Instead of optimization using a single colony of FSs (solutions), the MO-RCCACO consists of r subcolonies of size N cooperatively optimizing an FS that consists of r rules, with a subcolony optimizing only a single fuzzy rule. In addition, an auxiliary colony is created to store all of the fuzzy rules in the best-so-far N FSs to enhance the optimization ability of MO-RCCACO. The performance ranking of different fuzzy rules in the same subcolony is performed based on the multiobjective function values of their participating FSs by using Pareto nondominated sorting and the crowding distance. The MO-RCCACO is applied to find the Pareto-optimal fuzzy controllers (FCs) of a mobile robot for wall following with multiple control objectives. The optimization ability of the MO-RCCACO is verified through comparisons with various multiobjective population-based optimization algorithms in the robot wall-following control problem. Experimental results verify the effectiveness of the MO-RCCACO-based FCs for the boundary following control of a real robot.

AB - An integrated fault estimation (FE) and fault-tolerant tracking control (FTTC) strategy is developed for Lipschitz nonlinear multiagent systems subject to actuator faults, external disturbance, and uncertainties. First, for each agent, a corresponding unknown input observer with reduced/full order is constructed to obtain the FE. Then, a state/output feedback FTTC strategy is proposed based on the integral sliding-mode technique and adaptive super-twisting algorithm. The observer and controller gains are obtained simultaneously via Hinfinity optimization with a linear matrix inequality formulation. Finally, the comparison simulations are provided to demonstrate the effectiveness of the proposed algorithm. PMID- 30296251 TI - A Multipopulation-Based Multiobjective Evolutionary Algorithm. AB - Multipopulation is an effective optimization component often embedded into evolutionary algorithms to solve optimization problems. In this paper, a new multipopulation-based multiobjective genetic algorithm (MOGA) is proposed, which uses a unique cross-subpopulation migration process inspired by biological processes to share information between subpopulations. Then, a Markov model of the proposed multipopulation MOGA is derived, the first of its kind, which provides an exact mathematical model for each possible population occurring simultaneously with multiple objectives. Simulation results of two multiobjective test problems with multiple subpopulations justify the derived Markov model, and show that the proposed multipopulation method can improve the optimization ability of the MOGA. Also, the proposed multipopulation method is applied to other multiobjective evolutionary algorithms (MOEAs) for evaluating its performance against the IEEE Congress on Evolutionary Computation multiobjective benchmarks. The experimental results show that a single-population MOEA can be extended to a multipopulation version, while obtaining better optimization performance. PMID- 30296252 TI - Overexpression of Epidermal Growth Factor Receptor (EGFR) and HER-2 in Bladder Carcinoma and Its Association with Patients' Clinical Features. AB - BACKGROUND The aim of this study was to determine the expression of EGFR/HER-2 and investigate their association with patients' clinical features in bladder transitional cell carcinoma (BTCC). MATERIAL AND METHODS Immunohistochemistry was utilized in our study to explore the expression of EGFR/HER-2 of 56 human bladder cancer samples and 10 normal bladder samples. RESULTS EGFR and HER-2 expressions were both significantly higher in bladder transitional cell carcinoma (BTCC) than that in non-cancer bladder samples; the EGFR positivity rate was 55.4% among BTCC samples and 37.5% for HER-2a. A statistically significant correlation was also present between the increasing EGFR or HER-2 expression levels and the clinical stages, pathologic grades, and tumor recurrence. The expression level of EGFR increased along with higher clinical stages and pathologic grades of BTCC, and the obviously increased expression of HER-2 was statistically associated with clinical stages and tumor recurrence. In addition, the expression level of HER-2 increased along with the higher clinical stage of BTCC. EGFR expression and HER-2 levels were positively associated in BTCC samples. CONCLUSIONS Our findings demonstrate that high EGFR and HER-2 expressions are dramatically increased in the BTCC tissues and are closely related to the clinical stages, pathologic grades, and tumor recurrence. Therefore, the evaluation of EGFR and HER-2 expression in BTCC may contribute to identifying patients who are at increased risk of disease progression and recurrence. PMID- 30296253 TI - Candida albicans biofilm-induced vesicles confer drug resistance through matrix biogenesis. AB - Cells from all kingdoms of life produce extracellular vesicles (EVs). Their cargo is protected from the environment by the surrounding lipid bilayer. EVs from many organisms have been shown to function in cell-cell communication, relaying signals that impact metazoan development, microbial quorum sensing, and pathogenic host-microbe interactions. Here, we have investigated the production and functional activities of EVs in a surface-associated microbial community or biofilm of the fungal pathogen Candida albicans. Crowded communities like biofilms are a context in which EVs are likely to function. Biofilms are noteworthy because they are encased in an extracellular polymeric matrix and because biofilm cells exhibit extreme tolerance to antimicrobial compounds. We found that biofilm EVs are distinct from those produced by free-living planktonic cells and display strong parallels in composition to biofilm matrix material. The functions of biofilm EVs were delineated with a panel of mutants defective in orthologs of endosomal sorting complexes required for transport (ESCRT) subunits, which are required for normal EV production in diverse eukaryotes. Most ESCRT defective mutations caused reduced biofilm EV production, reduced matrix polysaccharide levels, and greatly increased sensitivity to the antifungal drug fluconazole. Matrix accumulation and drug hypersensitivity of ESCRT mutants were reversed by addition of wild-type (WT) biofilm EVs. Vesicle complementation showed that biofilm EV function derives from specific cargo proteins. Our studies indicate that C. albicans biofilm EVs have a pivotal role in matrix production and biofilm drug resistance. Biofilm matrix synthesis is a community enterprise; prior studies of mixed cell biofilms have demonstrated extracellular complementation. Therefore, EVs function not only in cell-cell communication but also in the sharing of microbial community resources.

AB - Mutations in Cu/Zn superoxide dismutase 1 (SOD1) lead to Amyotrophic Lateral Sclerosis (ALS), a neurodegenerative disease that disproportionately affects glutamatergic and cholinergic motor neurons. Previous work with SOD1 overexpression models supports a role for SOD1 toxic gain of function in ALS pathogenesis. However, the impact of SOD1 loss of function in ALS cannot be directly examined in overexpression models. In addition, overexpression may obscure the contribution of SOD1 loss of function in the degeneration of different neuronal populations. Here, we report the first single-copy, ALS knock in models in C. elegans generated by transposon- or CRISPR/Cas9- mediated genome editing of the endogenous sod-1 gene. Introduction of ALS patient amino acid changes A4V, H71Y, L84V, G85R or G93A into the C. elegans sod-1 gene yielded single-copy/knock-in ALS SOD1 models. These differ from previously reported overexpression models in multiple assays. In single-copy/knock-in models, we observed differential impact of sod-1 ALS alleles on glutamatergic and cholinergic neurodegeneration. A4V, H71Y, G85R, and G93A animals showed increased SOD1 protein accumulation and oxidative stress induced degeneration, consistent with a toxic gain of function in cholinergic motor neurons. By contrast, H71Y, L84V, and G85R lead to glutamatergic neuron degeneration due to sod-1 loss of function after oxidative stress. However, dopaminergic and serotonergic neuronal populations were spared in single-copy ALS models, suggesting a neuronal-subtype specificity previously not reported in invertebrate ALS SOD1 models. Combined, these results suggest that knock-in models may reproduce the neurotransmitter type specificity of ALS and that both SOD1 loss and gain of toxic function differentially contribute to ALS pathogenesis in different neuronal populations. PMID- 30296254 TI - Protection induced by a Francisella tularensis subunit vaccine delivered by glucan particles. AB - Francisella tularensis is an intracellular pathogen causing the disease tularemia, and an organism of concern to biodefence. There is no licensed vaccine available. Subunit approaches have failed to induce protection, which requires both humoral and cellular immune memory responses, and have been hampered by a lack of understanding as to which antigens are immunoprotective. We undertook a preliminary in silico analysis to identify candidate protein antigens. These antigens were then recombinantly expressed and encapsulated into glucan particles (GPs), purified Saccharomyces cerevisiae cell walls composed primarily of beta 1,3-glucans. Immunological profiling in the mouse was used to down-selection to seven lead antigens: FTT1043 (Mip), IglC, FTT0814, FTT0438, FTT0071 (GltA), FTT0289, FTT0890 (PilA) prior to transitioning their evaluation to a Fischer 344 rat model for efficacy evaluation. F344 rats were vaccinated with the GP protein antigens co-delivered with GP-loaded with Francisella LPS. Measurement of cell mediated immune responses and computational epitope analysis allowed down selection to three promising candidates: FTT0438, FTT1043 and FTT0814. Of these, a GP vaccine delivering Francisella LPS and the FTT0814 protein was able to induce protection in rats against an aerosol challenge of F. tularensis SchuS4, and reduced organ colonisation and clinical signs below that which immunisation with a GP-LPS alone vaccine provided. This is the first report of a protein supplementing protection induced by LPS in a Francisella vaccine. This paves the way for developing an effective, safe subunit vaccine for the prevention of inhalational tularemia, and validates the GP platform for vaccine delivery where complex immune responses are required for prevention of infections by intracellular pathogens. PMID- 30296256 TI - Recombination hotspots in an extended human pseudoautosomal domain predicted from double-strand break maps and characterized by sperm-based crossover analysis. AB - The human X and Y chromosomes are heteromorphic but share a region of homology at the tips of their short arms, pseudoautosomal region 1 (PAR1), that supports obligate crossover in male meiosis. Although the boundary between pseudoautosomal and sex-specific DNA has traditionally been regarded as conserved among primates, it was recently discovered that the boundary position varies among human males, due to a translocation of ~110 kb from the X to the Y chromosome that creates an extended PAR1 (ePAR). This event has occurred at least twice in human evolution. So far, only limited evidence has been presented to suggest this extension is recombinationally active. Here, we sought direct proof by examining thousands of gametes from each of two ePAR-carrying men, for two subregions chosen on the basis of previously published male X-chromosomal meiotic double-strand break (DSB) maps. Crossover activity comparable to that seen at autosomal hotspots was observed between the X and the ePAR borne on the Y chromosome both at a distal and a proximal site within the 110-kb extension. Other hallmarks of classic recombination hotspots included evidence of transmission distortion and GC-biased gene conversion. We observed good correspondence between the male DSB clusters and historical recombination activity of this region in the X chromosomes of females, as ascertained from linkage disequilibrium analysis; this suggests that this region is similarly primed for crossover in both male and female germlines, although sex-specific differences may also exist. Extensive resequencing and inference of ePAR haplotypes, placed in the framework of the Y phylogeny as ascertained by both Y microsatellites and single nucleotide polymorphisms, allowed us to estimate a minimum rate of crossover over the entire ePAR region of 6-fold greater than genome average, comparable with pedigree estimates of PAR1 activity generally. We conclude ePAR very likely contributes to the critical crossover function of PAR1. PMID- 30296258 TI - Examining food intake and eating out of home patterns among university students. AB - Eating out of home (OH) is increasingly popular in Balkan countries, among them Albania. To date there is only anecdotal evidence regarding nutritional quality of food consumed OH and the contribution to diet. This study assessed intake of foods and drinks consumed OH and at home (AH), as well as their nutritional contribution to the daily diet of university students in Tirana, Albania. Using a single day Automated Multiple Pass Method (AMPM) 24-hour dietary recall, we examined food intake among 289 students aged 18-24 years old, from three major universities in Albania. Contribution of eating OH to total energy intake per day, as well as to daily consumption of macronutrients by eating OH intensity tertiles were assessed. Foods and drinks consumed OH contributed 46.9% [95%CI:41.4-52.8] of total daily energy intake, representing, on average, 1169.1kcal [95%CI:1088.3-1249.9]. Sweets, soft drinks and meat products were more frequently consumed OH, while fruits and vegetables consumption was extremely low. The average quantity of sugars and dietary fats per day was higher AH, 76.9g [95%CI:70.3-83.5] and 173.7g [95%CI:163.2-184.2] respectively, compared to OH, 33.7g [95%CI:30.4-37.0] and 142.0g [95%CI:131.5-152.5] respectively. Dietary composition of AH intake was richer in sugars, total fats and proteins, while OH intake was richer in saturated fats. The overall diet appeared unhealthy, when nutrients were assessed as energy percentage against WHO proposed nutrient standards for sugar and saturated fats. Eating OH, even though was associated with lower fruits and vegetables intake, was not clearly associated with poor diet quality, as AH foods were also characterized by increased saturated fats and sugars intake as energy percentage. This study provides data on the first assessment of current dietary patterns of the studied population and can be used as baseline for designing and conducting future studies and interventions targeting malnutrition in all its forms. PMID- 30296257 TI - The design of schistosomiasis monitoring and evaluation programmes: The importance of collecting adult data to inform treatment strategies for Schistosoma mansoni. AB - Monitoring and evaluation (M&E) programmes are used to collect data which are required to assess the impact of current interventions on their progress towards achieving the World Health Organization (WHO) goals of morbidity control and elimination as a public health problem for schistosomiasis. Prevalence and intensity of infection data are typically collected from school-aged children (SAC) as they are relatively easy to sample and are thought to be most likely to be infected by schistosome parasites. However, adults are also likely to be infected. We use three different age-intensity profiles of infection for Schistosoma mansoni with low, moderate and high burdens of infection in adults to investigate how the age distribution of infection impacts the mathematical model generated recommendations of the preventive chemotherapy coverage levels required to achieve the WHO goals. We find that for moderate prevalence regions, regardless of the burden of infection in adults, treating SAC only may achieve the WHO goals. However, for high prevalence regions with a high burden of infection in adults, adult treatment is required to meet the WHO goals. Hence, we show that the optimal treatment strategy for a defined region requires consideration of the burden of infection in adults as it cannot be based solely on the prevalence of infection in SAC. Although past epidemiological data have informed mathematical models for the transmission and control of schistosome infections, more accurate and detailed data are required from M&E programmes to accurately determine the optimal treatment strategy for a defined region. We highlight the importance of collecting prevalence and intensity of infection data from a broader age-range, specifically the inclusion of adult data at baseline (prior to treatment) and throughout the treatment programme if possible, rather than SAC only, to accurately determine the treatment strategy for a defined region. Furthermore, we discuss additional epidemiological data, such as individual longitudinal adherence to treatment, that should ideally be collected in M&E programmes. PMID- 30296259 TI - Identifying a sufficient core group for trachoma transmission. AB - BACKGROUND: In many infectious diseases, a core group of individuals plays a disproportionate role in transmission. If these individuals were effectively prevented from transmitting infection, for example with a perfect vaccine, then the disease would disappear in the remainder of the community. No vaccine has yet proven effective against the ocular strains of chlamydia that cause trachoma. However, repeated treatment with oral azithromycin may be able to prevent individuals from effectively transmitting trachoma. METHODOLOGY/PRINCIPAL FINDINGS: Here we assess several methods for identifying a core group for trachoma, assuming varying degrees of knowledge about the transmission process. We determine the minimal core group from a completely specified model, fitted to results from a large Ethiopian trial. We compare this benchmark to a core group that could actually be identified from information available to trachoma programs. For example, determined from the rate of return of infection in a community after mass treatments, or from the equilibrium prevalence of infection. CONCLUSIONS/SIGNIFICANCE: Sufficient groups are relatively easy for programs to identify, but will likely be larger than the theoretical minimum. PMID- 30296260 TI - In-silico dynamic analysis of cytotoxic drug administration to solid tumours: Effect of binding affinity and vessel permeability. AB - The delivery of blood-borne therapeutic agents to solid tumours depends on a broad range of biophysical factors. We present a novel multiscale, multiphysics, in-silico modelling framework that encompasses dynamic tumour growth, angiogenesis and drug delivery, and use this model to simulate the intravenous delivery of cytotoxic drugs. The model accounts for chemo-, hapto- and mechanotactic vessel sprouting, extracellular matrix remodelling, mechano sensitive vascular remodelling and collapse, intra- and extravascular drug transport, and tumour regression as an effect of a cytotoxic cancer drug. The modelling framework is flexible, allowing the drug properties to be specified, which provides realistic predictions of in-vivo vascular development and structure at different tumour stages. The model also enables the effects of neoadjuvant vascular normalisation to be implicitly tested by decreasing vessel wall pore size. We use the model to test the interplay between time of treatment, drug affinity rate and the size of the vessels' endothelium pores on the delivery and subsequent tumour regression and vessel remodelling. Model predictions confirm that small-molecule drug delivery is dominated by diffusive transport and further predict that the time of treatment is important for low affinity but not high affinity cytotoxic drugs, the size of the vessel wall pores plays an important role in the effect of low affinity but not high affinity drugs, that high affinity cytotoxic drugs remodel the tumour vasculature providing a large window for the normalisation of the vascular architecture, and that the combination of large pores and high affinity enhances cytotoxic drug delivery efficiency. These results have implications for treatment planning and methods to enhance drug delivery, and highlight the importance of in-silico modelling in investigating the optimisation of cancer therapy on a personalised setting. PMID- 30296261 TI - One size does not fit all: Caste and sex differences in the response of bumblebees (Bombus impatiens) to chronic oral neonicotinoid exposure. AB - Neonicotinoid insecticides have been implicated in the rapid global decline of bumblebees over recent years, particularly in agricultural and urban areas. While there is much known about neonicotinoid toxicity effects at the colony stage of the bumblebee annual cycle, far less is known about such effects at other stages critical for the maintenance of wild populations. In the present work, individual based feeding assays were used to show that chronic consumption of the widely used neonicotinoid clothianidin at a field-realistic average rate of 3.6 and 4.0 ng/g.bee/day reduces survival of queen and male bumblebees, respectively, within a 7-day period. In contrast, worker survival was unaffected at a similar consumption rate of 3.9 ng/g.bee/day. To test the hypothesis that males have a lower tolerance for oral clothianidin exposure than workers due to their haploid genetic status, RNAseq analysis was used to compare the transcriptomic responses of workers and males to chronic intake of clothianidin at a sub-lethal dose of 0.37ng/bee/day for 5 days. Surprisingly, clothianidin consumption only altered the expression of 19 putative detoxification genes in a sex-specific manner, with 11/19 genes showing increased expression in workers. Sub-lethal clothianidin exposure also altered the expression of 40 genes associated with other major biological functions, including locomotion, reproduction, and immunity. Collectively, these results suggest that chronic oral toxicity effects of neonicotinoids are greatest during mating and nest establishment phases of the bumblebee life cycle. Chronic oral toxicity testing on males and queens is therefore required in order to fully assess the impact of neonicotinoids on wild bumblebee populations. PMID- 30296262 TI - Interactive reservoir computing for chunking information streams. AB - Chunking is the process by which frequently repeated segments of temporal inputs are concatenated into single units that are easy to process. Such a process is fundamental to time-series analysis in biological and artificial information processing systems. The brain efficiently acquires chunks from various information streams in an unsupervised manner; however, the underlying mechanisms of this process remain elusive. A widely-adopted statistical method for chunking consists of predicting frequently repeated contiguous elements in an input sequence based on unequal transition probabilities over sequence elements. However, recent experimental findings suggest that the brain is unlikely to adopt this method, as human subjects can chunk sequences with uniform transition probabilities. In this study, we propose a novel conceptual framework to overcome this limitation. In this process, neural networks learn to predict dynamical response patterns to sequence input rather than to directly learn transition patterns. Using a mutually supervising pair of reservoir computing modules, we demonstrate how this mechanism works in chunking sequences of letters or visual images with variable regularity and complexity. In addition, we demonstrate that background noise plays a crucial role in correctly learning chunks in this model. In particular, the model can successfully chunk sequences that conventional statistical approaches fail to chunk due to uniform transition probabilities. In addition, the neural responses of the model exhibit an interesting similarity to those of the basal ganglia observed after motor habit formation. PMID- 30296264 TI - The effect of assortative mixing on stability of low helminth transmission levels and on the impact of mass drug administration: Model explorations for onchocerciasis. AB - BACKGROUND: Stable low pre-control prevalences of helminth infection are not uncommon in field settings, yet it is poorly understood how such low levels can be sustained, thereby challenging efforts to model them. Disentangling possible facilitating mechanisms is important, since these may differently affect intervention impact. Here we explore the role of assortative (i.e. non homogenous) mixing and exposure heterogeneity in helminth transmission, using onchocerciasis as an example. METHODOLOGY/PRINCIPAL FINDINGS: We extended the established individual-based model ONCHOSIM to allow for assortative mixing, assuming that individuals who are relatively more exposed to fly bites are more connected to each other than other individuals in the population as a result of differential exposure to a sub-population of blackflies. We used the model to investigate how transmission stability, equilibrium microfilarial (mf) prevalence and intensity, and impact of mass drug administration depend on the assumed degree of assortative mixing and exposure heterogeneity, for a typical rural population of about 400 individuals. The model clearly demonstrated that with homogeneous mixing and moderate levels of exposure heterogeneity, onchocerciasis could not be sustained below 35% mf prevalence. In contrast, assortative mixing stabilised onchocerciasis prevalence at levels as low as 8% mf prevalence. Increasing levels of assortative mixing significantly reduced the probability of interrupting transmission, given the same duration and coverage of mass drug administration. CONCLUSIONS/SIGNIFICANCE: Assortative mixing patterns are an important factor to explain stable low prevalence situations and are highly relevant for prospects of elimination. Their effect on the pre-control distribution of mf intensities in human populations is only detectable in settings with mf prevalences <30%, where high skin mf density in mf-positive people may be an indication of assortative mixing. Local spatial variation in larval infection intensity in the blackfly intermediate host may also be an indicator of assortative mixing. PMID- 30296263 TI - Noncoding RNA Ginir functions as an oncogene by associating with centrosomal proteins. AB - Long noncoding RNAs constitute a major fraction of the eukaryotic transcriptome, and together with proteins, they intricately fine-tune various growth regulatory signals to control cellular homeostasis. Here, we describe the functional characterisation of a novel pair of long intergenic noncoding RNAs (lincRNAs) comprised of complementary, fully overlapping sense and antisense transcripts Genomic Instability Inducing RNA (Ginir) and antisense RNA of Ginir (Giniras), respectively, from mouse cells. This transcript pair is expressed in a spatiotemporal manner during embryonic development. The individual levels of the sense and antisense transcripts are finely balanced during embryonic growth and in adult tissues. Functional studies of the individual transcripts performed using overexpression and knock-down strategies in mouse cells has led to the discovery that Ginir RNA is a regulator of cellular proliferation and can act as an oncogene having a preeminent role in malignant transformation. Mechanistically, we demonstrate that the oncogenic function of Ginir is mediated by its interaction with centrosomal protein 112 (Cep112). Additionally, we establish here a specific interaction between Cep112 with breast cancer type 1 susceptibility protein (Brca1), another centrosome-associated protein. Next, we prove that the mutual interaction between Cep112 with Brca1 is significant for mitotic regulation and maintenance of genomic stability. Furthermore, we demonstrate that the Cep112 protein interaction with Brca1 protein is impaired when an elevated level of Ginir RNA is present in the cells, resulting in severe deregulation and abnormality in mitosis, leading to malignant transformation. Inhibiting the Ginir RNA function in transformed cells attenuates transformation and restores genomic stability. Together, these findings unravel, to our knowledge, a hitherto-unknown mechanism of oncogenesis mediated by a long noncoding RNA and establishes a unique role of Cep112-Brca1 interaction being modulated by Ginir RNA in maintaining mitotic fidelity. PMID- 30296265 TI - Quantifying how constraints limit the diversity of viable routes to adaptation. AB - Convergent adaptation occurs at the genome scale when independently evolving lineages use the same genes to respond to similar selection pressures. These patterns of genetic repeatability provide insights into the factors that facilitate or constrain the diversity of genetic responses that contribute to adaptive evolution. A first step in studying such factors is to quantify the observed amount of repeatability relative to expectations under a null hypothesis. Here, we formulate a novel index to quantify the constraints driving the observed amount of repeated adaptation in pairwise contrasts based on the hypergeometric distribution, and then generalize this for simultaneous analysis of multiple lineages. This index is explicitly based on the probability of observing a given amount of repeatability by chance under a given null hypothesis and is readily compared among different species and types of trait. We also formulate an index to quantify the effective proportion of genes in the genome that have the potential to contribute to adaptation. As an example of how these indices can be used to draw inferences, we assess the amount of repeatability observed in existing datasets on adaptation to stress in yeast and climate in conifers. This approach provides a method to test a wide range of hypotheses about how different kinds of factors can facilitate or constrain the diversity of genetic responses observed during adaptive evolution. PMID- 30296266 TI - Quantifying the value of surveillance data for improving model predictions of lymphatic filariasis elimination. AB - BACKGROUND: Mathematical models are increasingly being used to evaluate strategies aiming to achieve the control or elimination of parasitic diseases. Recently, owing to growing realization that process-oriented models are useful for ecological forecasts only if the biological processes are well defined, attention has focused on data assimilation as a means to improve the predictive performance of these models. METHODOLOGY AND PRINCIPAL FINDINGS: We report on the development of an analytical framework to quantify the relative values of various longitudinal infection surveillance data collected in field sites undergoing mass drug administrations (MDAs) for calibrating three lymphatic filariasis (LF) models (EPIFIL, LYMFASIM, and TRANSFIL), and for improving their predictions of the required durations of drug interventions to achieve parasite elimination in endemic populations. The relative information contribution of site-specific data collected at the time points proposed by the WHO monitoring framework was evaluated using model-data updating procedures, and via calculations of the Shannon information index and weighted variances from the probability distributions of the estimated timelines to parasite extinction made by each model. Results show that data-informed models provided more precise forecasts of elimination timelines in each site compared to model-only simulations. Data streams that included year 5 post-MDA microfilariae (mf) survey data, however, reduced each model's uncertainty most compared to data streams containing only baseline and/or post-MDA 3 or longer-term mf survey data irrespective of MDA coverage, suggesting that data up to this monitoring point may be optimal for informing the present LF models. We show that the improvements observed in the predictive performance of the best data-informed models may be a function of temporal changes in inter-parameter interactions. Such best data-informed models may also produce more accurate predictions of the durations of drug interventions required to achieve parasite elimination. SIGNIFICANCE: Knowledge of relative information contributions of model only versus data-informed models is valuable for improving the usefulness of LF model predictions in management decision making, learning system dynamics, and for supporting the design of parasite monitoring programmes. The present results further pinpoint the crucial need for longitudinal infection surveillance data for enhancing the precision and accuracy of model predictions of the intervention durations required to achieve parasite elimination in an endemic location. PMID- 30296267 TI - LytTR Regulatory Systems: A potential new class of prokaryotic sensory system. AB - The most commonly studied prokaryotic sensory signal transduction systems include the one-component systems, phosphosignaling systems, extracytoplasmic function (ECF) sigma factor systems, and the various types of second messenger systems. Recently, we described the regulatory role of two separate sensory systems in Streptococcus mutans that jointly control bacteriocin gene expression, natural competence development, as well as a cell death pathway, yet they do not function via any of the currently recognized signal transduction paradigms. These systems, which we refer to as LytTR Regulatory Systems (LRS), minimally consist of two proteins, a transcription regulator from the LytTR Family and a transmembrane protein inhibitor of this transcription regulator. Here, we provide evidence suggesting that LRS are a unique uncharacterized class of prokaryotic sensory system. LRS exist in a basal inactive state. However, when LRS membrane inhibitor proteins are inactivated, an autoregulatory positive feedback loop is triggered due to LRS regulator protein interactions with direct repeat sequences located just upstream of the -35 sequences of LRS operon promoters. Uncharacterized LRS operons are widely encoded by a vast array of Gram positive and Gram negative bacteria as well as some archaea. These operons also contain unique direct repeat sequences immediately upstream of their operon promoters indicating that positive feedback autoregulation is a globally conserved feature of LRS. Despite the surprisingly widespread occurrence of LRS operons, the only characterized examples are those of S. mutans. Therefore, the current study provides a useful roadmap to investigate LRS function in the numerous other LRS-encoding organisms. PMID- 30296268 TI - Ligand binding properties of two Brugia malayi fatty acid and retinol (FAR) binding proteins and their vaccine efficacies against challenge infection in gerbils. AB - Parasitic nematodes produce an unusual class of fatty acid and retinol (FAR) binding proteins that may scavenge host fatty acids and retinoids. Two FARs from Brugia malayi (Bm-FAR-1 and Bm-FAR-2) were expressed as recombinant proteins, and their ligand binding, structural characteristics, and immunogenicities examined. Circular dichroism showed that rBm-FAR-1 and rBm-FAR-2 are similarly rich in alpha-helix structure. Unexpectedly, however, their lipid binding activities were found to be readily differentiated. Both FARs bound retinol and cis-parinaric acid similarly, but, while rBm-FAR-1 induced a dramatic increase in fluorescence emission and blue shift in peak emission by the fluorophore-tagged fatty acid (dansyl-undecanoic acid), rBm-FAR-2 did not. Recombinant forms of the related proteins from Onchocerca volvulus, rOv-FAR-1 and rOv-FAR-2, were found to be similarly distinguishable. This is the first FAR-2 protein from parasitic nematodes that is being characterized. The relative protein abundance of Bm-FAR-1 was higher than Bm-FAR-2 in the lysates of different developmental stages of B. malayi. Both FAR proteins were targets of strong IgG1, IgG3 and IgE antibody in infected individuals and individuals who were classified as endemic normal or putatively immune. In a B. malayi infection model in gerbils, immunization with rBm-FAR-1 and rBm-FAR-2 formulated in a water-in-oil-emulsion ((r)Montanide-720) or alum elicited high titers of antigen-specific IgG, but only gerbils immunized with rBm-FAR-1 formulated with the former produced a statistically significant reduction in adult worms (68%) following challenge with B. malayi infective larvae. These results suggest that FAR proteins may play important roles in the survival of filarial nematodes in the host, and represent potential candidates for vaccine development against lymphatic filariasis and related filarial infections. PMID- 30296270 TI - Predicting position along a looping immune response trajectory. AB - When we get sick, we want to be resilient and recover our original health. To measure resilience, we need to quantify a host's position along its disease trajectory. Here we present Looper, a computational method to analyze longitudinally gathered datasets and identify gene pairs that form looping trajectories when plotted in the space described by these phases. These loops enable us to track where patients lie on a typical trajectory back to health. We analyzed two publicly available, longitudinal human microarray datasets that describe self-resolving immune responses. Looper identified looping gene pairs expressed by human donor monocytes stimulated by immune elicitors, and in YF17D vaccinated individuals. Using loops derived from training data, we found that we could predict the time of perturbation in withheld test samples with accuracies of 94% in the human monocyte data, and 65-83% within the same cohort and in two independent cohorts of YF17D vaccinated individuals. We suggest that Looper will be useful in building maps of resilient immune processes across organisms. PMID- 30296269 TI - Reactive oxygen species mediate conical cell shaping in Arabidopsis thaliana petals. AB - Plants have evolved diverse cell types with distinct sizes, shapes, and functions. For example, most flowering plants contain specialized petal conical epidermal cells that are thought to attract pollinators and influence light capture and reflectance, but the molecular mechanisms controlling conical cell shaping remain unclear. Here, through a genetic screen in Arabidopsis thaliana, we demonstrated that loss-of-function mutations in ANGUSTIFOLIA (AN), which encodes for a homolog of mammalian CtBP/BARs, displayed conical cells phenotype with wider tip angles, correlating with increased accumulation of reactive oxygen species (ROS). We further showed that exogenously supplied ROS generated similar conical cell phenotypes as the an mutants. Moreover, reduced endogenous ROS levels resulted in deceased tip sharpening of conical cells. Furthermore, through enhancer screening, we demonstrated that mutations in katanin (KTN1) enhanced conical cell phenotypes of the an-t1 mutants. Genetic analyses showed that AN acted in parallel with KTN1 to control conical cell shaping. Both increased or decreased ROS levels and mutations in AN suppressed microtubule organization into well-ordered circumferential arrays. We demonstrated that the AN-ROS pathway jointly functioned with KTN1 to modulate microtubule ordering, correlating with the tip sharpening of conical cells. Collectively, our findings revealed a mechanistic insight into ROS homeostasis regulation of microtubule organization and conical cell shaping. PMID- 30296271 TI - Vitamin D and macrophage polarization in epicardial adipose tissue of atherosclerotic swine. AB - Vitamin D functions as a potent immunomodulator by interacting with many immune cells however, its role in regulating inflammation in the epicardial adipose tissue (EAT) is unclear. In the EAT of atherosclerotic microswine that were fed with deficient, sufficient or supplemented levels of vitamin D, we evaluated the phenotype of the macrophages. Vitamin D treatment was continued for 12 months and serum 25(OH)D levels were measured regularly. Infiltration of M1/M2 macrophage was investigated by immunostaining for CCR7 and CD206, respectively in conjunction with a pan macrophage marker CD14. Significant difference in the number of CCR7+ cells was observed in the EAT from vitamin D-deficient swine compared to vitamin D-sufficient or -supplemented swine. Expression of CD206 correlated with high levels of serum 25(OH)D indicating a significant increase in M2 macrophages in the EAT of vitamin D-supplemented compared to -deficient swine. These findings suggest that vitamin D-deficiency exacerbates inflammation by increasing pro-inflammatory M1 macrophages, while vitamin D-supplementation attenuates the inflammatory cytokines and promotes M2 macrophages in EAT. This study demonstrates the significance of vitamin D mediated inhibition of macrophage mediated inflammation in the EAT during coronary intervention in addition to its immunomodulatory role. However, additional studies are required to identify the cellular mechanisms that transduce signals between macrophages and smooth muscle cells during restenosis in the presence and absence of vitamin D. PMID- 30296272 TI - Reference genes selection for quantitative gene expression studies in tea green leafhoppers, Empoasca onukii Matsuda. AB - Empoasca onukii Matsuda is one of the most devastating pests of the tea plant (Camellia sinensis). Still, the presumed expression stability of its reference genes (RGs) has not been analyzed. RGs are essential for accurate and reliable gene expression analysis, so this absence has hampered the study of the insect's molecular biology. To find candidate RGs for normalizing gene expression data, we cloned ten common housekeeping genes from E. onukii. Using the DeltaCt method, geNorm, NormFinder and BestKeeper, we screened the RGs that were appropriate for quantifying the mRNA transcription of cellular responses under five experimental conditions. We identified the combinations of alpha-TUB and G6PDH, alpha-TUB and UBC, two RGs (alpha-TUB and beta-TUB1) or three RGs (alpha-TUB, RPL13 and GAPDH), AK and UBC, or RPL13 and alpha-TUB as the best for analyzing gene expression in E. onukii adults of both sexes in different tissues, nymphs at different developmental stages, nymphs exposed to different temperatures or nymphs exposed to photoperiod stress. Finally, the E. onukii cysteine proteinase (Eocyp) was chosen as the target gene to validate the rationality of the proposed RGs. In conclusion, our study suggests a series of RGs with which to study the gene expression profiles of E. onukii that have been manipulated (biotically or abiotically) using reverse transcription quantitative polymerase chain reaction. The results offer a solid foundation for further studies of the molecular biology of E. onukii. PMID- 30296274 TI - Stabilization period before capturing an ultra-short vagal index can be shortened to 60 s in endurance athletes and to 90 s in university students. AB - PURPOSE: To find the shortest, acceptable stabilization period before recording resting, supine ultra-short-term Ln RMSSD and heart rate (HR). METHOD: Thirty endurance-trained male athletes (age 24.1 +/- 2.3 years, maximal oxygen consumption (VO2max) 64.1 +/- 6.6 ml.kg-1.min-1) and 30 male students (age 23.3 +/- 1.8 years, VO2max 52.8 +/- 5.1 ml.kg-1.min-1) were recruited. Upon awaking at home, resting, supine RR intervals were measured continuously for 10 min using a Polar V800 HR monitor. Ultra-short-term Ln RMSSD and HR values were calculated from 1-min RR interval segments after stabilization periods from 0 to 4 min in 0.5 min increments and were compared with reference values calculated from 5-min segment after 5-min stabilization. Systematic bias and intraclass correlation coefficients (ICC) including 90% confidence intervals (CI) were calculated and magnitude based inference was conducted. RESULTS: The stabilization periods of up to 30 s for athletes and up to 60 s for students showed positive (possibly to most likely) biases for ultra-short-term Ln RMSSD compared with reference values. Stabilization periods of 60 s for athletes and 90 s for students showed trivial biases and ICCs were 0.84; 90% CI 0.72 to 0.91, and 0.88; 0.79 to 0.94, respectively. For HR, biases were trivial and ICCs were 0.93; 0.88 to 0.96, and 0.93; 0.88 to 0.96, respectively. CONCLUSION: The shortest stabilization period required to stabilize Ln RMSSD and HR was set at 60 s for endurance-trained athletes and 90 s for university students. PMID- 30296273 TI - Monitoring the age-specificity of measles transmissions during 2009-2016 in Southern China. AB - BACKGROUND: Despite several immunization efforts, China saw a resurgence of measles in 2012. Monitoring of transmissions of individuals from different age groups could offer information that would be valuable for planning adequate disease control strategies. We compared the age-specific effective reproductive numbers (R) of measles during 2009-2016 in Guangdong, China. METHODS: We estimated the age-specific R values for 7 age groups: 0-8 months, 9-18 months, 19 months to 6 years, 7-15 years, 16-25 years, 26-45 years, and >=46 years adapting the contact matrix of China. The daily numbers of laboratory and clinically confirmed cases reported to the Center for Disease Control and Prevention of Guangdong were used. RESULTS: The peak R values of the entire population were above unity from 2012 to 2016, indicating the persistence of measles in the population. In general, children aged 0-6 years and adults aged 26-45 years had larger values of R when comparing with other age groups after 2012. While the peaks of R values for children aged 0-6 years dropped steadily after 2013, the peaks of R values for adults aged 26-45 years kept at a high range every year. CONCLUSIONS: Although the provincial supplementary immunization activities (SIAs) conducted in 2009 and 2010 were able to reduce the transmissions from 2009 to 2011, larger values of R for children aged 0-6 years were observed after 2012, indicating that the benefits of the SIAs were short-lived. In addition, the transmissions from adults aged between 26 and 45 years increased over time. Disease control strategies should target children and adult groups that carry high potential for measles transmission.

AB - A good understanding of species-habitat associations, or habitat use, is required to establish conservation strategies for any species. Many amphibian species are elusive and most information concerning amphibian habitat use comes from breeding sites where they are comparatively easy to find and study. Knowledge about retreat sites is extremely limited for most species and for the greater part of the year. For such species, it is especially important to factor in detection probability in habitat analyses, because otherwise distorted views about habitat preferences may result, e.g., when a species is more visible in habitat type B than in A, even though A may be preferred. The South American red-belly toad, Melanophryniscus pachyrhynus, is a range-restricted species from Southern Brazil and Uruguay that inhabits open areas with rocky outcrops and is usually seen only during explosive breeding events. Here we studied the fine-scale habitat use of the red-belly toad outside of the breeding season to identify retreat sites and test for the importance of accounting for species imperfect detection, using Bayesian occupancy models. We identified shrub density and the number of loose rocks as important predictors of occupancy, while detection probability was highest at intermediate temperatures. Considering the harsh (dry and hot) conditions of rocky outcrops, shrubs and loose rocks may both work as important refuges, besides providing food resources and protecting against predation. Rocky outcrops have been suffering changes in habitat configuration and we identify nonbreeding habitat preferences at a fine scale, which may help to promote population persistence, and highlight the importance of accounting for imperfect detection when studying secretive species. PMID- 30296277 TI - Elevated cytokine levels in vitreous as biomarkers of disease severity in infectious endophthalmitis. AB - PURPOSE: To investigate the immunopathogenesis of endophthalmitis, and determine if cytokine profiles could serve as biomarkers of disease severity in infectious endophthalmitis. MATERIALS AND METHODS: Vitreous samples of 46 patients clinically diagnosed as endophthalmitis (of which 25 were culture positive) and 20 non-infectious controls from patients with Retinal Detachment (RD) or diabetic retinopathy were included in the study. The cytokine and chemokine expression patterns of 40 immune mediators including 6 antiinflammatory cytokines, 15 proinflammatory cytokines, 9 Growth factors and 10 proinflammatory chemokines in the vitreous were were analyzed by multiplex cytokine immunoassay. In addition, significant immune mediators were correlated with initial and final visual acuity (VA). RESULTS: Our results demonstrated elevated expression of 16 mediators such as GCSF, GRO, IFN-gamma, IL-1alpha, IL-1beta, IL-1 RA, IL-6, IL-8, IP-10, MCP-1, MCP-3, MIP-1alpha, IL-1beta, TGF-alpha, TNF-alpha in patients with culture positive endophthalmitis. Cytokine profile expression significantly differed between patients with proven endophthalmitis and the non-infectious controls in heat map analysis. PCoA plot indicated five mediators (IL-1RA, IL-6, IL-8, GRO, G CSF) as biomarkers that could be Independent Predictors of Disease especially in culture negative cases. Correlation of cytokines with VA revealed strong association between the initial VA and intraocular levels of TGF-alpha, IL-1beta and IL-8 but there was no correlation with the severity or visual outcome of infection. CONCLUSION: In comparison to non-infectious ocular conditions, the pathogenesis of infectious endophthalmitis correlates with increased expression levels of IL-1RA, IL-6, IL-8, GRO, G-CSF. Understanding cytokine profiles in culture negative endophthalmitis patients could aid in therapy in non-responders to empirical antibiotic therapy. PMID- 30296278 TI - The evolution of cooperation in signed networks under the impact of structural balance. AB - Structural balance plays an important role in the dynamics of signed networks. Based on structural balance, we generalize the evolution of cooperation in signed networks. Here we develop a new simulation model to study the impact of structural balance on the evolution of cooperation in signed networks. The simulation shows that cooperation prevails when an individual has a higher probability of adjusting the signs of its relations. We also find that structural balance forces the coexistence of cooperators and defectors, while the initial attributes of networks have little impact on the evolution of cooperation in the presence of structural balance, although they have a strong effect on the evolution of structural balance. PMID- 30296276 TI - Adolescent binge ethanol-induced loss of basal forebrain cholinergic neurons and neuroimmune activation are prevented by exercise and indomethacin. AB - Basal forebrain cholinergic neurons mature in adolescence coinciding with development of adult cognitive function. Preclinical studies using the rodent model of adolescent intermittent ethanol (AIE; 5.0 g/kg, i.g., 2-days on/2-days off from postnatal day [P]25 to P55) reveal persistent increases of brain neuroimmune genes that are associated with cognitive dysfunction. Adolescent intermittent ethanol exposure also reduces basal forebrain expression of choline acetyltransferase (ChAT), an enzyme critical for acetylcholine synthesis in cholinergic neurons similar to findings in the post-mortem human alcoholic basal forebrain. We report here that AIE decreases basal forebrain ChAT+IR neurons in both adult female and male Wistar rats following early or late adolescent ethanol exposure. In addition, we find reductions in ChAT+IR somal size as well as the expression of the high-affinity nerve growth factor (NGF) receptor tropomyosin receptor kinase A (TrkA) and the low-affinity NGF receptor p75NTR, both of which are expressed on cholinergic neurons. The decrease in cholinergic neuron marker expression was accompanied by increased phosphorylation of NF-kappaB p65 (pNF kappaB p65) consistent with increased neuroimmune signaling. Voluntary wheel running from P24 to P80 prevented AIE-induced cholinergic neuron shrinkage and loss of cholinergic neuron markers (i.e., ChAT, TrkA, and p75NTR) as well as the increase of pNF-kappaB p65 in the adult basal forebrain. Administration of the anti-inflammatory drug indomethacin (4.0 mg/kg, i.p prior to each ethanol exposure) during AIE also prevented the loss of basal forebrain cholinergic markers and the concomitant increase of pNF-kappaB p65. In contrast, treatment with the proinflammatory immune activator lipopolysaccharide (1.0 mg/kg, i.p. on P70) caused a loss of cholinergic neuron markers that was paralleled by increased pNF-kappaB p65 in the basal forebrain. These novel findings are consistent with AIE causing lasting activation of the neuroimmune system that contributes to the persistent loss of basal forebrain cholinergic neurons in adulthood. PMID- 30296279 TI - Differentiation and quantification of fibrosis, fat and fatty fibrosis in human left atrial myocardium using ex vivo MRI. AB - BACKGROUND: Atrial fibrillation is associated with an atrial cardiomyopathy composed mainly of fibrosis and adipose tissue accumulation. We hypothesized that MRI, when used in an optimal ex vivo setting allowing high spatial resolution without motion artifacts, can help characterizing the complex 3D left atrial (LA) wall composition in human myocardial samples, as compared to histology. METHODS: This prospective case-control study was approved by the institutional review board. 3D MRI acquisitions including saturation-recovery T1 mapping and DIXON imaging was performed at 4.0 T on 9 human LA samples collected from patients who underwent cardiac surgery. Histological quantification of fibrosis and fat was obtained. MRI T1 maps were clustered based on a Gaussian Mixture Model allowing quantification of total, interstitial and fatty fibrosis components. Fat maps were computed from DIXON images and fat fractions were calculated. MRI measurements were performed on the same location as the histological analysis (plane) and on the entire sample volume (3D). RESULTS: High correlations and levels of agreement were observed between MRI and histology for total (r = 0.93), interstitial (r = 0.93) and fatty fibrosis (r = 0.98) and fat (r = 0.96). Native T1 correlated with the amount of fibrosis from MRI and histology. The 3D MRI total, interstitial and fatty fibrosis ranges were between 6% and 23%, 4% and 17.3%; and 1.4% and 19.7% respectively. CONCLUSION: High Field ex vivo MRI was able to quantify different LA myocardial components with high agreement in 2D with histology and moreover to provide 3D quantification of such components whereas in vivo application remains a challenge. PMID- 30296280 TI - Galactography is not an obsolete investigation in the evaluation of pathological nipple discharge. AB - PURPOSE: To evaluate the malignancy rate and diagnostic performance of galactography in patients with pathological nipple discharge (PND) after negative clinical breast examination, mammography and ultrasound. MATERIALS AND METHODS: We retrospectively evaluated all galactograms obtained between January 2006 and December 2014 in women with PND. Galactographic findings were classified into 6 groups according to a modified Galactogram Image Classification system (GICS) to comply with the breast imaging reporting and data system classification. Observers were blinded to the final histology and clinical outcome at the time of analysis. MRI was performed as a problem solving ancillary examination. Imaging findings, pathological diagnosis and follow-up data were evaluated. The diagnostic performance of MRI and technically successful galactography in the detection of neoplastic or risk lesions were separately calculated. RESULTS: A total of 146 patients with PND (mean age, 51.5 years; range, 17-93) were examined. Malignant lesions were detected in only 4 patients (2.7%) and risk lesions in 5 patients (3.4%). Only one low-grade ductal carcinoma in situ was missed by galactography (GICS 1) and MRI. MRI examinations were performed in 21 (14.4%) patients; one of these patients (4.8%) had a malignant finding (GICS 0), two (9.5%) had risk-lesions (GICS 2 and 5). In the detection of neoplastic or risk lesions the sensitivity and specificity of galactography were 77.4% and 75.7% and of MRI 85.7% and 71.4%, consecutively. CONCLUSION: The malignancy rate is negligible if clinical, mammography, ultrasound and galactography examinations are negative. Galactography remains a practical, valuable and cost-effective examination procedure. If galactography is technically unsuccessful, MRI should be considered as an additional ancillary tool to evaluate the possible etiology of symptoms, but the routine use of MRI in all patients cannot be justified. PMID- 30296281 TI - Deceptive nest defence in ground-nesting birds and the risk of intermediate strategies. AB - Nest predation is an important determinant of reproductive success and ground nesting birds exhibit a variety of nest defence strategies to mitigate the risk. Many small-bodied, ground nesting birds rely on deceptive behaviours such as injury-feigning to reduce nest predation: we call this behaviour active deception. However, active deception may entail risks to adults, and passive deceptive behaviour, where individuals effectively sneak away from the nest by flushing at long distances, may be an alternative means of avoiding nest predation. We provide a simple model to demonstrate that these tails of the flush distance distribution could minimize predation risk; an intermediate strategy of moderate flush distances means that birds flush more often than with short distance flushes, and once flushed, the nest is more easily located than for long distance flushes. We tested this model using two species of ground nesting shorebirds, the White-rumped Sandpiper (Calidris fuscicollis) and the Red Phalarope (Phalaropus fulicarius). We demonstrate that short-distance flushes are associated with active deception and intermediate-distance flushes are associated with an increased risk of nest predation. However, we found no evidence that this potential selective pressure against intermediate strategies has produced a bimodal distribution of nest defence traits. The heritability of defence behaviours, or the ability of individuals to learn, is unknown and other factors such as energetic constraints or risks to adults might also influence flush distances and defence behaviours. PMID- 30296282 TI - Root growth, function and rhizosphere microbiome analyses show local rather than systemic effects in apple plant response to replant disease soil. AB - Apple replant disease (ARD) is the phenomenon of soil decline occurring after repeated planting of apple trees at the same site. This study aimed to elucidate whether ARD is systemic, i.e. whether the contact of parts of the root system with ARD soil causes the whole plant to show poor shoot and root growth. A split root experiment was conducted with seedlings of 'M26', offering the same plant for its root system the choice between the substrates ARD soil (+ARD), gamma sterilized ARD soil (-ARD) or soil from a grass parcel (Control) with the following combinations: +ARD/+ARD, -ARD/-ARD; +ARD/-ARD; +ARD/Control. Root growth was analysed throughout the 34-day growing period. Samples from bulk, rhizosphere and rhizoplane soil were collected separately for each compartment, and analysed by fingerprints of 16S rRNA gene or ITS fragments amplified from total community (TC) DNA. The response of the plant to +ARD was not systemic as root growth in -ARD compartment was always superior to root growth in +ARD soil. Crosswise 15N-labelling of the N-fertilizer applied to the split-root compartments showed that nitrate-N uptake efficiency was higher for roots in -ARD soil compared to those in +ARD. Bacterial and fungal community composition in the rhizoplane and rhizosphere of the same plants differed significantly between the compartments containing +ARD/-ARD or +ARD/Control. The strongest differences between the bacterial fingerprints were observed in the rhizoplane and rhizosphere. Bacterial genera with increased abundance in response to ARD were mainly Streptomyces but also Sphingobium, Novosphingobium, Rhizobium, Lysobacter and Variovorax. The strongest differences between the fungal fingerprints were observed in bulk soil. Our data showed that the response of the apple plant to ARD soil is local and not systemic. PMID- 30296283 TI - Impact of social capital, harassment of women and girls, and water and sanitation access on premature birth and low infant birth weight in India. AB - BACKGROUND: Globally, preterm birth (PTB) and low infant birth weight (LBW) are leading causes of maternal and child morbidity and mortality. Inadequate water and sanitation access (WASH) are risk factors for PTB and LBW in low-income countries. Physical stress from carrying water and psychosocial stress from addressing sanitation needs in the open may be mechanisms underlying these associations. If so, then living in a community with strong social capital should be able to buffer the adverse effects of WASH on birth outcomes. The objective of this study is to assess the relationships between WASH access and social conditions (including harassment and social capital) on PTB and LBW outcomes among Indian women, and to test whether social conditions modified the association between WASH and birth outcomes. METHODS AND FINDINGS: This cohort study examined the effect of pre-birth WASH and social conditions on self reported PTB status and LBW status for 7,926 women who gave birth between 2004/2005 and 2011/2012 Waves of the India Human Development Survey. PTB and LBW occurred in 14.9% and 15.5% of women, respectively. After adjusting for maternal biological and socioeconomic conditions, PTB was associated with sharing a building/compound latrine (Odds Ratio (OR) = 1.55; 95% Confidence Interval (CI) = 1.01, 2.38) versus private latrine access, but suggested an effect in the opposite direction for sharing a community/public latrine (OR = 0.67; CI = 0.45, 1.01). Open defecation, type of drinking water source, minutes per day spent fetching water, and one-way time to a drinking water source were not associated with PTB. LBW was associated with spending more than two hours per day fetching water compared to less than two hours (OR = 1.33; CI = 1.05, 1.70) and suggested an association with open defecation (OR = 1.22; CI = 1.00, 1.48), but was not associated with other types of sanitation, type of drinking water source, or time to a drinking water source. Harassment of women and girls in the community was associated with both PTB (OR = 1.33; CI = 1.09, 1.62) and LBW (OR = 1.26; CI = 1.03, 1.54). The data also showed a possible association of local crime with LBW (OR = 1.30; CI = 1.00, 1.68). Statistically significant (p<0.05) evidence of effect modification was only found for collective efficacy on the association between type of sanitation access and PTB. In addition, stratified analyses identified differences in effect size for walking time to the primary drinking water source and PTB by crime, sanitation access and PTB by harassment, and total hours per day fetching water and LBW by collective efficacy. Limitations of this observational study include risk of bias, inability to confirm causality, reliance on self-reported outcomes, and limited sub-group sample sizes for testing effect modification. CONCLUSIONS: The relationship between adverse birth outcomes and sanitation access, domestic water fetching, crime, and gender-based harassment suggests physical and psychosocial stress are possible mechanisms by which WASH access affects PTB and LBW among Indian women. Interventions that reduce domestic responsibilities related to water and sanitation and change social norms related to gender-based harassment may reduce rates of PTB and LBW in India. PMID- 30296284 TI - Establishment of five immortalized human ovarian surface epithelial cell lines via SV40 T antigen or HPV E6/E7 expression. AB - BACKGROUND: Human ovarian surface epithelial (HOSE) cells are a critical cell source for ovarian cancer research; however, they are difficult to obtain and maintain under standard laboratory conditions in large quantities. The aim of this study was to generate immortalized HOSE (IHOSE) cells with maintained properties to the original cell source, thereby guaranteeing a sufficiently large cell quantity for ovarian cancer research. METHODS: HOSE cells isolated from four non-cancer patients and five IHOSE cell lines were established by induction of HPV-E6/E7 expression or SV40 large T antigen using a lenti-viral system. Each of IHOSE cells was confirmed to be distinct by STR profiling. RNA-sequencing was used to compare gene expression profiles in HOSE, IHOSE and ovarian cancer cells. RESULTS: RNA-sequencing results revealed a stronger linear correlation in gene expression between IHOSE and HOSE cells (R2 = 0.9288) than between IHOSE or HOSE cells and ovarian cancer cells (R2 = 0.8562 and R2 = 0.7982, respectively). The gene expression pattern of 319 differentially expressed genes revealed minimal differences between HOSE and IHOSE cells, while a strong difference between ovarian cancer cells and HOSE or IHOSE cells was observed. Furthermore, the five IHOSE cell lines displayed morphological characteristics typical of epithelial cells but showed a lower level of EpCAM, CD133 and E-cadherin, as cancer stem marker, than ovarian cancer cells. Moreover, unlike cancer cells, IHOSE cells could not form colonies in the anchorage-independent soft agar growth assay. CONCLUSION: These findings demonstrate that five newly established IHOSE cell lines have characteristics of progenitor HOSE cells while exhibiting continuous growth, and thus, should be highly useful as control cells for ovarian cancer research. PMID- 30296285 TI - Seagrass and macrophyte mediated CO2 and CH4 dynamics in shallow coastal waters. AB - Seagrass meadows are among the most important coastal/ marine ecosystems for long term carbon storage and conditioning of coastal waters. A combined air-water flux of CO2 and CH4 from the seagrass meadows was studied for the first time from Asia's largest brackish-water lagoon, Chilika, India. Ecosystem-based comparisons were carried out during two hydrologically different conditions of dry and wet seasons in the seagrass dominated southern sector (SS); macrophyte-dominated northern sector (NS); the largely un-vegetated central sector (CS) and the tidally active outer channel (OC) of the lagoon. The mean fluxes of CO2 from SS, NS, CS and OC were 9.8, 146.6, 48.4 and 33.0mM m-2d-1, and that of CH4 were 0.12, 0.11, 0.05 and 0.07mM m-2d-1, respectively. The net emissions (in terms of CO2 equivalents), considering the global warming potential of CO2 (GWP: 1) and CH4 (GWP: 28) from seagrass meadows were over 14 times lower compared to the macrophyte-dominated sector of the lagoon. Contrasting emissivity characteristics of CO2 and CH4 were observed between macrophytes and seagrass, with the former being a persistent source of CO2. It is inferred that although seagrass meadows act as a weak source of CH4, they could be effective sinks of CO2 if land-based pollution sources are minimized. PMID- 30296286 TI - Sports participation in sport clubs, gyms or public spaces: How users of different sports settings differ in their motivations, goals, and sports frequency. AB - BACKGROUND: To develop targeted policy strategies to increase sports participation, more insight is needed into the behavioural patterns and preferences of users of different club-organized (i.e., sports clubs) and non club organized (i.e., gyms, health centres or swimming pools) or informal sports settings such as public spaces. This study investigates 1) how users of different settings differ regarding self-determined motivations and goals, and sociodemographic and sports-related characteristics, and 2) how the association of motivations and goals with sports participation may differ between users of different sports settings. METHODS: Data were collected through online surveys among Dutch adults aged 18-80 years (N = 910). Ordinal regression analyses were used to investigate the effects of sports settings, the level of self-determined motivations and goals, and interaction effects of motivations and goals with different sports settings, on sports frequency. RESULTS: Users of different sports settings differed in their personal characteristics, motivations and goals. In general, controlled motivations were negatively associated with sports frequency (B = -0.46). However, among club members, extrinsic goals related to image (B = 0.44), as well as intrinsic goals related to skill development (B = 0.40) and social affiliation (B = 0.47) had significant positive associations with sports frequency. Health-related goals significantly increased sports frequency among users of informal settings, such as public spaces. CONCLUSION: The association of motivational variables with sports participation differs between settings. This implies that sports frequency is higher when participants engage in settings that better fit their motivations and goals. Because of the growing importance of informal and flexible settings and health goals, professionals in the sports and health domains should take into account the motivations, goals and needs of different target groups who (want to) use unorganized, informal sports settings including public spaces. PMID- 30296287 TI - Field evaluation of the BG-Malaria trap for monitoring malaria vectors in rural Tanzanian villages. AB - BG-Malaria (BGM) trap is a simple adaptation of the widely-used BG-Sentinel trap (BGS). It is proven to be highly effective for trapping the Brazilian malaria vector, Anopheles darlingi, in field conditions, and the African vector, Anopheles arabiensis, under controlled semi-field environments, but has not been field-tested in Africa. Here, we validated the BGM for field sampling of malaria vectors in south-eastern Tanzania. Using a series of Latin-Square experiments conducted nightly (6pm-7am) in rural villages, we compared mosquito catches between BGM, BGS and human landing catches (HLC). We also compared BGMs baited with different attractants (Ifakara-blend, Mbita-blend, BG-Lure and CO2). Lastly, we tested BGMs baited with Ifakara-blend from three odour-dispensing methods (BG Cartridge, BG-Sachet and Nylon strips). One-tenth of the field-collected female Anopheles gambiae s.l. and Anopheles funestus were dissected to assess parity. BGM captured more An. gambiae s.l. than BGS (p < 0.001), but HLC caught more than either trap (p < 0.001). However, BGM captured more An. funestus than HLC. Proportions of parous An. gambiae s.l. and An. funestus consistently exceeded 50%, with no significant difference between methods. While the dominant species caught by HLC was An. gambiae s.l. (56.0%), followed by Culex spp. (33.1%) and Mansonia spp. (6.0%), the BGM caught mostly Culex (81.6%), followed by An. gambiae s.l. (10.6%) and Mansonia (5.8%). The attractant-baited BGMs were all significantly superior to un-baited controls (p < 0.001), although no difference was found between the specific attractants. The BG-Sachet was the most efficient dispenser for capturing An. gambiae s.l. (14.5(2.75-42.50) mosquitoes/trap/night), followed by BG-Cartridge (7.5(1.75-26.25)). The BGM caught more mosquitoes than BGS in field-settings, but sampled similar species diversity and physiological states as BGS. The physiological states of malaria vectors caught in BGM and BGS were similar to those naturally attempting to bite humans (HLC). The BGM was most efficient when baited with Ifakara blend, dispensed from BG-Sachet. We conclude that though BGM traps have potential for field-sampling of host-seeking African malaria vectors with representative physiological states, both BGM and BGS predominantly caught more culicines than Anopheles, compared to HLC, which caught mostly An. gambiae s.l. PMID- 30296288 TI - Tobacco smoke exposure is an independent predictor of vitamin D deficiency in US children. AB - IMPORTANCE: The role of tobacco-smoke exposure on serum vitamin D concentration in US pediatric population is not known. We hypothesized that tobacco smoke exposure would increase the prevalence of vitamin D deficiency in US children. METHODS: Representative national data were accessed from the National Health and Nutrition Examination Survey (NHANES) 2009-2010 databank on 2,263 subjects of ages 3 to 17 years. Subjects were categorized into two groups based on their age: children, if <10 years; and youth if 10 to 17 years. Descriptive and multiple logistic regression analyses were conducted to determine the effect of serum cotinine-verified tobacco smoke exposure on vitamin D status after controlling for key sociodemographic confounders. Vitamin D deficiency was defined as 25(OH)D <20 ng/mL, insufficiency as 25(OH)D of 20-29.9 ng/mL, and sufficiency as 25(OH)D of >=30 ng/mL. Tobacco smoke exposure status was defined by serum cotinine concentration as follows: unexposed and non-smoking (<0.05 ng/mL) and exposed (passive and active smokers combined) (>=0.05ng/mL). Specifically, passive and active smoking were defined as cotinine of 0.05-10 ng/mL, and >=10ng/mL respectively. RESULTS: The prevalence of second-hand smoke exposure was 42.0% (95%CI, 36.7%-47.5%); while the prevalence of active smoking among teenagers was 9.0% (95%CI, 6.2%-12.5%). Vitamin D deficiency occurred at a frequency of 15.1% in children unexposed to tobacco smoke, 20.9% in children exposed to passive tobacco smoke, and 18.0% among actively smoking youth (p<0.001). Tobacco smoke exposure independently predicted vitamin D deficiency after controlling for age, sex, race, BMI, maternal education, and family socio-economic status (OR:1.50; 95%CI, 1.14-1.85, p = 0.002). CONCLUSIONS: This analysis of a nationwide database reports that tobacco smoke exposure is an independent predictor of vitamin D deficiency in US children. PMID- 30296289 TI - Correcting geometric distortions in stereoscopic 3D imaging. AB - Motion in a distorted virtual 3D space may cause visually induced motion sickness. Geometric distortions in stereoscopic 3D can result from mismatches among image capture, display, and viewing parameters. Three pairs of potential mismatches are considered, including 1) camera separation vs. eye separation, 2) camera field of view (FOV) vs. screen FOV, and 3) camera convergence distance (i.e., distance from the cameras to the point where the convergence axes intersect) vs. screen distance from the observer. The effect of the viewer's head positions (i.e., head lateral offset from the screen center) is also considered. The geometric model is expressed as a function of camera convergence distance, the ratios of the three parameter-pairs, and the offset of the head position. We analyze the impacts of these five variables separately and their interactions on geometric distortions. This model facilitates insights into the various distortions and leads to methods whereby the user can minimize geometric distortions caused by some parameter-pair mismatches through adjusting of other parameter pairs. For example, in postproduction, viewers can correct for a mismatch between camera separation and eye separation by adjusting their distance from the real screen and changing the effective camera convergence distance. PMID- 30296290 TI - Automated classification of synaptic vesicles in electron tomograms of C. elegans using machine learning. AB - Synaptic vesicles (SVs) are a key component of neuronal signaling and fulfil different roles depending on their composition. In electron micrograms of neurites, two types of vesicles can be distinguished by morphological criteria, the classical "clear core" vesicles (CCV) and the typically larger "dense core" vesicles (DCV), with differences in electron density due to their diverse cargos. Compared to CCVs, the precise function of DCVs is less defined. DCVs are known to store neuropeptides, which function as neuronal messengers and modulators [1]. In C. elegans, they play a role in locomotion, dauer formation, egg-laying, and mechano- and chemosensation [2]. Another type of DCVs, also referred to as granulated vesicles, are known to transport Bassoon, Piccolo and further constituents of the presynaptic density in the center of the active zone (AZ), and therefore are important for synaptogenesis [3]. To better understand the role of different types of SVs, we present here a new automated approach to classify vesicles. We combine machine learning with an extension of our previously developed vesicle segmentation workflow, the ImageJ macro 3D ART VeSElecT. With that we reliably distinguish CCVs and DCVs in electron tomograms of C. elegans NMJs using image-based features. Analysis of the underlying ground truth data shows an increased fraction of DCVs as well as a higher mean distance between DCVs and AZs in dauer larvae compared to young adult hermaphrodites. Our machine learning based tools are adaptable and can be applied to study properties of different synaptic vesicle pools in electron tomograms of diverse model organisms. PMID- 30296292 TI - Models of turfgrass seed germination related to water content. AB - Turfgrasses have been widely utilized by humans to enhance the environment for more than several centuries. Seed germination is of great importance in the development of the turfgrass industry. In this study, the seed germination models of the responses of three types of turfgrasses to water were studied. The results indicated that irrigation water was mainly related to the variation of seed volume rather than a fixed value in this experiment. The maximum k value of tall fescue, Kentucky bluegrass and perennial ryegrass is 1.1548, 1.6946 and 4.0940, respectively. The optimal value of k is 1.0617 for tall fescue, 1.4610 for Kentucky bluegrass, and 1.6614 for perennial ryegrass. Perennial ryegrass seeds are more sensitive to water than those of tall fescue and Kentucky bluegrass, and this turfgrass is the fastest to reach the maximum value of the germination rate. Based on the results from the present experiment, the seed germination function can describe the response of turfgrass seed germination to external water content variation and their sensitivities. The function obtained could be used to perform quantitative studies on the dynamic changes of seed germination under different water conditions that will contribute to improved predictions of the optimal fitting curves of the germination over a range of water.

AB - Visualization of the complex 3D architecture of myocardial scar could improve guidance of radio-frequency ablation in the treatment of ventricular tachycardia (VT). In this study, we sought to develop a framework for 3D holographic visualization of myocardial scar, imaged using late gadolinium enhancement (LGE), on the augmented reality HoloLens. 3D holographic LGE model was built using the high-resolution 3D LGE image. Smooth endo/epicardial surface meshes were generated using Poisson surface reconstruction. For voxel-wise 3D scar model, every scarred voxel was rendered into a cube which carries the actual resolution of the LGE sequence. For surface scar model, scar information was projected on the endocardial surface mesh. Rendered layers were blended with different transparency and color, and visualized on HoloLens. A pilot animal study was performed where 3D holographic visualization of the scar was performed in 5 swines who underwent controlled infarction and electroanatomic mapping to identify VT substrate. 3D holographic visualization enabled assessment of the complex 3D scar architecture with touchless interaction in a sterile environment. Endoscopic view allowed visualization of scar from the ventricular chambers. Upon completion of the animal study, operator and mapping specialist independently completed the perceived usefulness questionnaire in the six-item usefulness scale. Operator and mapping specialist found it useful (usefulness rating: operator, 5.8; mapping specialist, 5.5; 1-7 scale) to have scar information during the intervention. HoloLens 3D LGE provides a true 3D perception of the complex scar architecture with immersive experience to visualize scar in an interactive and interpretable 3D approach, which may facilitate MR-guided VT ablation. PMID- 30296293 TI - Immunomodulatory activity of a novel polysaccharide from Lonicera japonica in immunosuppressed mice induced by cyclophosphamide. AB - Lonicera japonica is a typical Chinese herbal medicine. We previously reported a method to isolate polysaccharides from Lonicera japonica (LJP). In this study, we first performed a qualitative analysis of LJP using the Fourier Transform Infrared Spectrometer (FT-IR) and explored the monosaccharide composition of LJP using the pre-column derivatization high performance liquid chromatography (HPLC) method. We then investigated the immunomodulatory function of LJP in cyclophosphamide (CTX)-induced immunosuppressed mouse models. The results showed that LJP had the characteristic absorption of typical polysaccharides consisting of 6 types of monosaccharides. In addition, LJP can increase significantly the organ index, splenic lymphocyte proliferation, macrophage phagocytosis, and natural killer (NK) cell activity in CTX-treated mice. LJP could also restore the levels of serum cytokines interleukin (IL-2), tumor necrosis factor (TNF-alpha) and Interferon-gamma (IFN-gamma) in the CTX-treated mice. Finally, the results on measuring the T-lymphocytes subsets of spleen also confirmed LJP-induced immunomodulatory activity in immunosuppressed mice from another perspective. Therefore, LJP could be used as a potential immunomodulatory agent. PMID- 30296294 TI - The workforce trends of physician assistants in Iowa (1995-2015). AB - BACKGROUND: Physician assistants are expected to have an important role in providing both primary and specialty care. Iowa has a large rural (and aging) population and faces challenges to provide equitable access to care. This study examined changes in the Iowa physician assistant workforce (1995-2015) focusing on practice setting (primary v. subspecialty care) and geographic location (rural/urban, Health Professional Shortage Area). Documenting their current locations and service in HPSAs for primary care will help health planners track future changes. METHODS: Data from 1995-2015 from the Iowa Health Professions Inventory (Office of Statewide Clinical Education Programs, Carver College of Medicine, University of Iowa) were combined with US census data on rural location and HPSA status. SPSS was used to compare Iowa and national data. Growth trends were analyzed using joinpoint regression. RESULTS: The overall Iowa physician assistant workforce increased 161% between 1995 and 2015. In 2015, more than two thirds (71%) were female and more than 30% practiced in rural counties. The average annual growth rate of primary care PAs (per 100,000 population) was significantly higher in the periods from 1995-1997 and 1997-2001 (22.4% and 7.4% respectively) than in period from 2001-2015 (3.8%). By 2015, 56% of Iowa's physician assistants practiced in primary care (versus 29.6% nationally). Of these, 44% of primary care physician assistants in Iowa practiced in counties, geographic locations or worksites designated as Health Professional Shortage Areas for primary care. CONCLUSIONS: A high proportion of Iowa's physician assistant workforce practiced in primary care and many served patients in Health Professional Shortage Areas. The number of physician assistants in Iowa will continue to grow and serve an important role in providing access to health care, particularly to rural Iowans. PMID- 30296296 TI - Laser surgery reveals the biomechanical and chemical signaling functions of aphid siphunculi (cornicles). AB - Aphids are an attractive food source to many predators and parasitoids because of their small size, soft bodies and slow movement. To combat predation, aphids evolved both behavioral and chemical defensive mechanisms that are operated via siphunculi (cornicles), differently developed structures that more or less extend from their abdomen. Although both direct and indirect linkages between siphunculi and their defensive mechanisms have been explored, their ultimate effects on aphid fitness are still broadly debated. To explicitly test the influence of siphunculi on brown citrus aphid, Aphis (Toxoptera) citricida (Kirkaldy), fitness, we razor-cut and laser-sealed the siphunculi. Siphunculi removal resulted in two distinct behavior modifications, (false aggregation and increased drop-off rates) that led to decreased survival and the loss of the ability to right themselves from an inverted position. These results together indicate that siphunculi play an important role in survival, and removal of these organs will have negative effect on aphid fitness. Furthermore, results suggested that released alarm pheromone may play an important role in communication among aphid clone-mate, and omitting it results in miscommunication and competition among clonemates. These findings will help in better understanding the aphid biology. PMID- 30296295 TI - The role of case proximity in transmission of visceral leishmaniasis in a highly endemic village in Bangladesh. AB - BACKGROUND: Visceral leishmaniasis (VL) is characterised by a high degree of spatial clustering at all scales, and this feature remains even with successful control measures. VL is targeted for elimination as a public health problem in the Indian subcontinent by 2020, and incidence has been falling rapidly since 2011. Current control is based on early diagnosis and treatment of clinical cases, and blanket indoor residual spraying of insecticide (IRS) in endemic villages to kill the sandfly vectors. Spatially targeting active case detection and/or IRS to higher risk areas would greatly reduce costs of control, but its effectiveness as a control strategy is unknown. The effectiveness depends on two key unknowns: how quickly transmission risk decreases with distance from a VL case and how much asymptomatically infected individuals contribute to transmission. METHODOLOGY/PRINCIPAL FINDINGS: To estimate these key parameters, a spatiotemporal transmission model for VL was developed and fitted to geo-located epidemiological data on 2494 individuals from a highly endemic village in Mymensingh, Bangladesh. A Bayesian inference framework that could account for the unknown infection times of the VL cases, and missing symptom onset and recovery times, was developed to perform the parameter estimation. The parameter estimates obtained suggest that, in a highly endemic setting, VL risk decreases relatively quickly with distance from a case-halving within 90m-and that VL cases contribute significantly more to transmission than asymptomatic individuals. CONCLUSIONS/SIGNIFICANCE: These results suggest that spatially-targeted interventions may be effective for limiting transmission. However, the extent to which spatial transmission patterns and the asymptomatic contribution vary with VL endemicity and over time is uncertain. In any event, interventions would need to be performed promptly and in a large radius (>=300m) around a new case to reduce transmission risk. PMID- 30296297 TI - Somatosensory and transcranial motor evoked potential monitoring in a porcine model for experimental procedures. AB - Evoked potential monitoring has evolved as an essential tool not only for elaborate neurological diagnostics, but also for general clinical practice. Moreover, it is increasingly used to guide surgical procedures and prognosticate neurological outcome in the critical care unit, e.g. after cardiac arrest. Experimental animal models aim to simulate a human-like scenario to deduct relevant clinical information for patient treatment and to test novel therapeutic opportunities. Porcine models are particularly ideal due to a comparable cardiovascular system and size. However, certain anatomic disparities have to be taken into consideration when evoked potential monitoring is used in animal models. We describe a non-invasive and reproducible set-up useful for different modalities in porcine models. We further illustrate hints to overcome multi faceted problems commonly occurring while using this sophisticated technique. Our descriptions can be used to answer a plethora of experimental questions, and help to further facilitate experimental therapeutic innovation. PMID- 30296298 TI - Assessing psychological and physical abuse from children's perspective: Factor structure and psychometric properties of the picture-based, modularized child report version of the Parent-Child Conflict Tactics Scale - Revised (CTSPC-R). AB - Child victims' reports of psychological and physical abuse by caregivers are a fundamental source of information beyond official records and caregiver reports. However, few or no sensitive and age-appropriate child-report instruments exist that have undergone in-depth validity and reliability testing across a broad age range. Our study addresses this gap by examining psychometric properties of a picture-based, modularized version of the Parent-Child Conflict Tactics Scale (CTSPC-R), encompassing the maltreatment subtypes of psychological and physical abuse. A sample of 904 children and adolescents aged 4-16 years from the community (n = 568), child psychiatric services (n = 159), and from Child Protective Services (CPS; n = 177) completed the CTSPC-R. Measures to test convergent (maltreatment in parent interviews and CPS records) and concurrent validity (psychiatric symptoms) were collected. The CTSPC-R comprises 22 items, arranged in three severity modules by increasing level of psychological and physical abuse by caregivers. Companion picture cards were provided for children aged 4 and 8 years. The best fit to the data was attained with a second-order factor model, assuming three inter-correlated factors corresponding to the three severity modules, and a latent second-order factor representing combined physical and psychological abuse. The three factors showed good internal consistencies. Supporting convergent validity at the global and subtype-level of maltreatment, the CTSPC-R severity scale was associated with lifetime CPS-contact, presence of caregiver-reported emotional maltreatment and physical abuse, and dimensions of chronicity and severity. Discriminant validity was supported by non-significant correlations with caregiver-reported lack of supervision, failure to provide, and sexual abuse. Bolstering concurrent validity, moderate and severe physical abuse predicted caregiver-reported internalizing and externalizing symptoms. These effects were independent of child age, gender or community vs. non-community samples. Our study supports the CTSPC-R as a scientifically and clinically sound tool for ascertaining the child's own perspective on psychological and physical abuse from an early age onwards. PMID- 30296299 TI - Automatic detection of cyberbullying in social media text. AB - While social media offer great communication opportunities, they also increase the vulnerability of young people to threatening situations online. Recent studies report that cyberbullying constitutes a growing problem among youngsters. Successful prevention depends on the adequate detection of potentially harmful messages and the information overload on the Web requires intelligent systems to identify potential risks automatically. The focus of this paper is on automatic cyberbullying detection in social media text by modelling posts written by bullies, victims, and bystanders of online bullying. We describe the collection and fine-grained annotation of a cyberbullying corpus for English and Dutch and perform a series of binary classification experiments to determine the feasibility of automatic cyberbullying detection. We make use of linear support vector machines exploiting a rich feature set and investigate which information sources contribute the most for the task. Experiments on a hold-out test set reveal promising results for the detection of cyberbullying-related posts. After optimisation of the hyperparameters, the classifier yields an F1 score of 64% and 61% for English and Dutch respectively, and considerably outperforms baseline systems. PMID- 30296300 TI - Barriers and facilitators to adoption and use of fuel pellets and improved cookstoves in urban Rwanda. AB - BACKGROUND: The environmental and health impacts of reliance on solid fuels and traditional cookstoves in low-income countries have motivated the promotion of household cooking energy systems that use cleaner burning fuels and cookstoves that lead to reduced exposure to harmful pollutants. Little is known about adoption and use of such systems from the users' perspective. METHODS: We explored the facilitators and barriers to adoption and use of a private sector marketed household cooking energy system that uses sustainably produced biomass pellets and the cleanest burning fan micro-gasification stove currently available. We conducted 48 in-depth qualitative interviews in Gisenyi, Rwanda with decision-makers and cooks in 16 households that adopted the improved cookstove system and 8 non-adopter households. RESULTS: Reported facilitators and barriers to adoption and non-adoption, as well as use and non-use were complex, and in some cases, contradictory. Some adopters noted that cleanliness and low smoke production were major facilitators to adoption and use, while other adopters and non-adopters said the cookstoves blackened and damaged cooking pots and produced excessive smoke. Our findings suggest that correct use of the stove mediates user experience. Cost was likewise reported as a facilitator among some adopters and a barrier among other adopters and non-adopters. Peer influence played a significant role as both a barrier and a facilitator to adoption and transcended other factors. Positive peer influence describing the cleanliness, affordability, and efficiency of the cookstove system encouraged adoption and use, while negative comments by peers regarding excessive smoke and damaged cooking pots discouraged adoption. Commentaries by some participants suggest that inadequate training and instruction may be primary causes of the discrepancies. CONCLUSION: Cost, cleanliness, communication among peer networks, and adequate training and instruction are important factors associated with the adoption and use of improved cookstoves and should be prioritized in the implementation of improved cookstove programs. PMID- 30296301 TI - Low frequency of asymptomatic dengue virus-infected donors in blood donor centers during the largest dengue outbreak in Taiwan. AB - To determine the prevalence of asymptomatic dengue virus-infected blood donors during the largest dengue outbreak in Taiwan history occurred in 2015, we examined the evidence of dengue virus (DENV) infection by the detection of DENV RNA genome using real-time reverse transcription-polymerase chain reaction (real time RT-PCR), DENV NS1 antigen using rapid diagnosis test (RDT) and anti-dengue antibody using IgM/IgG capture enzyme-linked immunosorbent assay (capture ELISA) and RDT in eight thousand serum samples from blood donations to the blood centers of the Taiwan Blood Services Foundation (TBSF) in Kaohsiung City and Tainan City during the largest dengue outbreak in Taiwan history occurred in 2015. Only one serum sample was positive for DENV RNA detection by using dengue-specific real time RT-PCR, the virus was DENV-2 determined by serotype-specific real-time RT PCR and sequencing, and the DENVs in the serum were confirmed as being infectious by a plaque assay. The recipient of this blood did not develop any dengue fever symptom on follow-up. None of the samples was NS1 RDT-reactive. Seventeen IgM positive samples were identified. There was a low prevalence of asymptomatic confirmed or probable DENV-infected blood donors in our study (0.013% and 0.21%, respectively), and no symptomatic transfusion-transmitted dengue (TT dengue) was developed during the largest dengue outbreak in Taiwan history in highly endemic areas and periods. PMID- 30296303 TI - Using a phiC31 "Disintegrase" to make new attP sites in the Drosophila genome at locations showing chromosomal position effects. AB - An engineered phiC31 "Disintegrase" able to make an attP site in Drosophila out of an attR-attL pair is described. This was used to generate attP sites at genomic locations where a mini-white (mini-w) transgene was subject to chromosomal position effects (CPE). The first step was random genomic integration of a P-element-based transposon with an insulated mini-w transgene. We then removed the upstream insulator using FLP recombinase to detect CPE. Next mini-w and the downstream insulator were "dis-integrated" leaving behind an attP site. The location is marked by a yellow+ transgene that is flanked by loxP sites, so it can also be removed. Using this system, we generated 10 new attP landing platforms. Three of these showing strong activating CPE were selected for further analysis. We show that the attP sites are functional by integrating in plasmids with attB sites. The CPE is recapitulated and can be blocked by insulators. We show that a dimerized 215 bp fragment of the 500 bp BEAF-dependent scs' insulator containing a high affinity BEAF binding site blocks the CPE, while a monomer of the sequence is less effective. This indicates that two BEAF binding sites make a stronger insulator than a single site. This system could be useful for generating attP sites at prescreened sites for other purposes, such as studying CPE in embryos or other tissues or for use with "trapped" enhancers of interest. PMID- 30296302 TI - Potent neutralizing antibodies in humans infected with zoonotic simian foamy viruses target conserved epitopes located in the dimorphic domain of the surface envelope protein. AB - Human diseases of zoonotic origin are a major public health problem. Simian foamy viruses (SFVs) are complex retroviruses which are currently spilling over to humans. Replication-competent SFVs persist over the lifetime of their human hosts, without spreading to secondary hosts, suggesting the presence of efficient immune control. Accordingly, we aimed to perform an in-depth characterization of neutralizing antibodies raised by humans infected with a zoonotic SFV. We quantified the neutralizing capacity of plasma samples from 58 SFV-infected hunters against primary zoonotic gorilla and chimpanzee SFV strains, and laboratory-adapted chimpanzee SFV. The genotype of the strain infecting each hunter was identified by direct sequencing of the env gene amplified from the buffy coat with genotype-specific primers. Foamy virus vector particles (FVV) enveloped by wild-type and chimeric gorilla SFV were used to map the envelope region targeted by antibodies. Here, we showed high titers of neutralizing antibodies in the plasma of most SFV-infected individuals. Neutralizing antibodies target the dimorphic portion of the envelope protein surface domain. Epitopes recognized by neutralizing antibodies have been conserved during the cospeciation of SFV with their nonhuman primate host. Greater neutralization breadth in plasma samples of SFV-infected humans was statistically associated with smaller SFV-related hematological changes. The neutralization patterns provide evidence for persistent expression of viral proteins and a high prevalence of coinfection. In conclusion, neutralizing antibodies raised against zoonotic SFV target immunodominant and conserved epitopes located in the receptor binding domain. These properties support their potential role in restricting the spread of SFV in the human population. PMID- 30296304 TI - Assessment of bleeding in patients with disseminated intravascular coagulation after receiving surgery and recombinant human soluble thrombomodulin: A cohort study using a database. AB - We aimed to investigate the incidence of bleeding-related adverse events (AEs) among patients with disseminated intravascular coagulation (DIC) receiving recombinant thrombomodulin (rTM) and those receiving other DIC treatments, the incidence by type of surgery, and the incidence when either blood transfusion or a hemostatic procedure was administered to treat DIC. In this cohort study, data were obtained from a large medical database (22 centers in Japan). The primary endpoint was the incidence rate of bleeding-related AEs by type of surgery. The secondary endpoint was the incidence rate of bleeding-related AEs based on whether blood transfusion or a hemostatic procedure was administered after the day of DIC treatment. In total, 4234 propensity score-matched patients were included in the main analysis (2117 patients each in the rTM and non-rTM groups). In the rTM and non-rTM groups, respectively, the incidence of bleeding-related AEs was 18.8% and 24.8% (p <0.001; risk ratio [RR] 0.757, 95% confidence interval [CI] 0.674-0.849), among patients requiring any type of surgery; 15.0% and 19.5% (p = 0.0001; RR 0.769, 95% CI 0.673-0.879) in patients requiring blood transfusion or a hemostatic procedure after the day of DIC treatment; 10.2% and 11.6% (p = 0.4470; RR 0.879, 95% CI 0.630-1.226) in patients undergoing hepatic, biliary, or pancreatic surgery; 24.3% and 25.4% (p = 0.6439; RR 0.955, 95% CI 0.786-1.160) in patients undergoing gastrointestinal surgeries; and 18.5% and 30.1% (p = 0.0001; RR 0.614, 95% CI 0.481-0.782) in patients undergoing cardiac or cardiovascular surgery. Our findings suggest that rTM treatment for Japanese postsurgical patients who develop DIC was associated with significantly fewer bleeding-related AEs compared with those receiving other DIC treatments. PMID- 30296305 TI - CXCL4 contributes to host defense against acute Pseudomonas aeruginosa lung infection. AB - Platelets have been implicated in pulmonary inflammation following exposure to bacterial stimuli. The mechanisms involved in the platelet-mediated host response to respiratory bacterial infection remain incompletely understood. In this study, we demonstrate that platelet-derived chemokine (C-X-C motif) ligand 4 (CXCL4) plays critical roles in a mouse model of acute bacterial pneumonia using Pseudomonas aeruginosa. Platelets are activated during P. aeruginosa infection, and mice depleted of platelets display markedly increased mortality and impaired bacterial clearance. CXCL4 deficiency impairs bacterial clearance and lung epithelial permeability, which correlate with decreased neutrophil recruitment to BALF. Interestingly, CXCL4 deficiency selectively regulates chemokine production, suggesting that CXCL4 has an impact on other chemokine expression. In addition, CXCL4 deficiency reduces platelet-neutrophil interactions in blood following P. aeruginosa infection. Further studies revealed that platelet-derived CXCL4 contributes to the P. aeruginosa-killing of neutrophils. Altogether, these findings demonstrate that CXCL4 is a vital chemokine that plays critical roles in bacterial clearance during P. aeruginosa infection through recruiting neutrophils to the lungs and intracellular bacterial killing. PMID- 30296307 TI - Renewable energy consumption and economic growth. Causality relationship in Central and Eastern European countries. AB - The new European model stipulates the achievement of an inclusive, sustainable and intelligent economic growth. Increasing the share of renewable energy is one of the factors that improve the quality of economic growth, similar to research, development and investment in human capital. In this paper we tested the correlation between economic growth and renewable energy consumption for ten European Union (EU) member states from Central and Eastern Europe (CEE) in the period 1990-2014, using Auto-regressive and Distributed Lag (ARDL) modeling procedure, a technique that captures causal relationships both on a short run and on a long run. The short run perspective reveals the transition towards a new energy paradigm, while the long run approach corresponds to the long-term equilibrium of the analyzed factors. Our results shows that, in the short run, the Gross Domestic Product (GDP) and Renewable Energy Consumption (REC) dynamics are independent in Romania and Bulgaria, while in Hungary, Lithuania and Slovenia an increasing renewable energy consumption improves the economic growth. The hypothesis of bi-directional causality between renewable energy consumption and economic growth is validated in the long run for both the whole group of analyzed countries as well as in the case of seven CEE states which were studied individually. These results allow us to look into the feasibility of the Europe 2020 goals regarding the increase of energy efficiency and to propose public policies to achieve these goals. PMID- 30296306 TI - Estrogen and mechanical loading-related regulation of estrogen receptor-beta and apoptosis in tendinopathy. AB - Female-dominant tendinopathies are musculoskeletal disorders caused by repetitive hand posture and motion; they are considered overuse syndromes. Both external mechanical stress and changes in hormone levels might affect disease progression. We have previously reported that estrogen receptor-beta (ER)-beta expression was associated with the pathogenesis of de Quervain's disease. To study the underlying mechanisms, a cyclic stretching culture system was applied to tendon tissue from ovariectomized (OVX) rats. Furthermore, a collagenase I-induced rat tendinopathy model was established to examine the association of ER-beta with disease progression. Our results showed that ER-beta expression and the number of apoptotic cells were higher and associated with disease severity in rats with tendinopathy. Mechanical stress altered the morphology of primary tenocytes and collagen fiber alignment in tendons, and up-regulated the expression of matrix metalloproteinase-9, ER-beta, and interleukin-1beta, as well as induced apoptosis in tenocytes and tendon tissue from OVX rats. This is the first report on the effects of ER-beta and mechanical stress in tendinopathy. We hope these findings contribute to new pharmacological therapies targeting ER-beta signaling pathways to treat tendon-related diseases. PMID- 30296310 TI - Mycobacterium abscessus: A Rare Cause of Periprosthetic Knee Joint Infection. AB - A 61-year-old woman with a periprosthetic knee joint infection caused by Mycobacterium abscessus was successfully treated with surgical debridement, multidrug antimicrobial therapy, and staged reimplantation. To the authors' knowledge, this represents the first report of successfully treating this organism after knee arthroplasty. M. abscessus knee infections are rare, and there are no specific guidelines to inform treatment or successful treatment regimens for periprosthetic knee infections. Medical management alone was not successful in this case and hence cannot be recommended. Using a collaborative multidisciplinary approach, including surgical debridement, staged reimplantation, and multidrug antimicrobials, successful eradication of the periprosthetic joint infection caused by M. abscessus was achieved. PMID- 30296309 TI - 5 Points on Meniscal Allograft Transplantation. AB - Meniscus allograft transplantation (MAT) has yielded excellent long-term functional outcomes when performed in properly indicated patients. When evaluating a patient for potential MAT, it is imperative to evaluate past medical history and past surgical procedures. The ideal MAT candidate is a chronologically and physiologically young patient (<50 years) with symptomatic meniscal deficiency. Existing pathology in the knee needs to be carefully considered and issues such as malalignment, cartilage defects, and/or ligamentous instability may require a staged or concomitant procedure. Once an ideal candidate is identified, graft selection and preparation are critical steps to ensure a proper fit and long-term viability of the meniscus. When selecting the graft, accurate measurements must be taken, and this is most commonly performed using plain radiographs for this. Graft fixation can be accomplished by placing vertical mattress sutures and tying those down with the knee in full extension. PMID- 30296308 TI - A novel 3D printed mechanical actuator using centrifugal force for magnetic resonance elastography: Initial results in an anthropomorphic prostate phantom. AB - This work demonstrates a new method for the generation of mechanical shear wave during magnetic resonance elastography (MRE) that creates greater forces at higher vibrational frequencies as opposed to conventionally used pneumatic transducers. We developed an MR-compatible pneumatic turbine with an eccentric mass that creates a sinusoidal centrifugal force. The turbine was assessed with respect to its technical parameters and evaluated for MRE on a custom-made anthropomorphic prostate phantom. The silicone-based tissue-mimicking materials of the phantom were selected with regard to their complex shear moduli examined by rheometric testing. The tissue-mimicking materials closely matched human soft tissue elasticity values with a complex shear modulus ranging from 3.21 kPa to 7.29 kPa. We acquired MRE images on this phantom at 3 T with actuation frequencies of 50, 60 Hz, 70 Hz, and 80 Hz. The turbine generated vibrational wave amplitudes sufficiently large to entirely penetrate the phantoms during the feasibility study. Increased wave length in the stiffer inclusions compared to softer background material were detected. Our initial results suggest that silicone-based phantoms are useful for the evaluation of elasticities during MRE. Furthermore, our turbine seems suitable for the mechanical assessment of soft tissue during MRE. PMID- 30296311 TI - A Three-View Radiographic Approach to Femoroacetabular Impingement. AB - Femoroacetabular impingement (FAI) is an abnormality of the hip joint that is increasingly being recognized as a cause of athletic disability and early degenerative hip disease. Despite significant advances in the knowledge of FAI, it remains a frequently unrecognized cause of hip pain in adolescents and young adults among orthopedic providers. The purpose of this article is to present a simple 3-view radiographic approach to young adults with hip pain. The radiographs include a standing anteroposterior view of the pelvis, a cross-table lateral view, and a false profile view. Good quality radiographs showing the common sites of potential impingement combined with a basic understanding of certain radiographic parameters may allow faster diagnosis, eliminate unnecessary studies, and allow earlier referral and management. PMID- 30296133 TI - Observation of Higgs Boson Decay to Bottom Quarks. AB - The observation of the standard model (SM) Higgs boson decay to a pair of bottom quarks is presented. The main contribution to this result is from processes in which Higgs bosons are produced in association with a W or Z boson (VH), and are searched for in final states including 0, 1, or 2 charged leptons and two identified bottom quark jets. The results from the measurement of these processes in a data sample recorded by the CMS experiment in 2017, comprising 41.3 fb^{-1} of proton-proton collisions at sqrt[s]=13 TeV, are described. When combined with previous VH measurements using data collected at sqrt[s]=7, 8, and 13 TeV, an excess of events is observed at m_{H}=125 GeV with a significance of 4.8 standard deviations, where the expectation for the SM Higgs boson is 4.9. The corresponding measured signal strength is 1.01+/-0.22. The combination of this result with searches by the CMS experiment for H->bb[over -] in other production processes yields an observed (expected) significance of 5.6 (5.5) standard deviations and a signal strength of 1.04+/-0.20. PMID- 30296312 TI - Analysis of Incidence and Outcome Predictors for Patients Admitted to US Hospitals with Acetabular Fractures from 1990 to 2010. AB - The incidence of acetabular fractures and associated in-hospital complication rates in the United States are poorly defined. Studies evaluating predictors of outcome for isolated acetabular fractures are weakly generalizable due to small sample sizes or the inclusion of all types of pelvic fractures. This study sought to analyze trends in acetabular fractures and associated complications in the US using the largest and most recent national dataset available. The National Hospital Discharge Survey was queried to identify all patients admitted to US hospitals with acetabular fractures between 1990 and 2010. A representative cohort of 497,389 patients was identified, and multivariable logistic regression was used to identify independent predictors of mortality, adverse events, requirement of blood transfusion, and operative treatment with open reduction and internal fixation (ORIF). Between 1990 and 2010, the population-adjusted incidence of acetabular fractures increased from 7.8 to 9.5/100,000 capita (P < .001). Mortality declined from 5.9% to 0.4% (P < .001), paralleling an increase in the proportion of patients treated with ORIF (12.6%-20.4%, P < .001), which was the variable associated with the lowest odds of mortality. Surgical intervention was associated with higher odds of adverse events and a requirement for blood transfusion. The average in-hospital length of stay decreased from 17.0 days to 10.3 days (P < .001). This study provides the largest and most comprehensive epidemiologic analysis of acetabular fractures in the US. Knowledge of the increasing incidence of acetabular fractures and prognostic factors associated with poor outcomes may improve outcomes. PMID- 30296313 TI - Arthroscopically-Guided, Cannulated, Headless Compression Screw Fixation of the Symptomatic Os Acromiale. AB - Os acromiale is a failure of fusion between 1 or more ossification centers of the scapula and the acromion process. Pain can be caused by motion and impingement of the unfused segment. Several methods for the management of os acromiale have been described. Internal fixation is the most common surgical technique, followed by excision and acromioplasty. We present a novel technique for treatment of symptomatic os acromiale using arthroscopically-guided headless compression screws. This is a viable technique in the management of symptomatic os acromiale due to preservation of the periosteal blood supply and less concern for symptomatic hardware. PMID- 30296314 TI - Complex Ankle and Hindfoot Arthrodesis Using Circular External Fixation. AB - Surgical reconstruction of the ankle and hindfoot in patients with diabetes, Charcot neuroarthropathy, osteomyelitis, deformity, and/or bone loss can be challenging and often results in amputation. In these patients, conventional internal fixation with plates, screws, and intramedullary nails is often not feasible because of ongoing infection or poor bone stock and soft tissue quality. The Ilizarov method of ankle and hindfoot arthrodesis is a well-established technique for limb reconstruction that uses circular external fixation to achieve solid bony fusion, optimal leg length, and eradication of infection in cases of complex pathology. This article discusses indications, contraindications, pearls, and pitfalls of performing ankle and hindfoot arthrodesis using the Ilizarov technique. PMID- 30296315 TI - Composite Fixation of Proximal Tibial Nonunions: A Technical Trick. AB - Nonunion after a proximal tibia fracture is often associated with poor bone stock, (previous) infection, and compromised soft tissues. These conditions make revision internal fixation with double plating difficult. Combining a plate and contralateral 2-pin external fixator, coined composite fixation, can provide an alternative means of obtaining stability without further compromising soft tissues. Three patients with a proximal tibia nonunion precluding standard internal fixation with double plating were treated with composite fixation. All 3 patients achieved union with deformity correction at a mean of 5.2 months (range, 5-5.5 months). The average range of motion (ROM) arc was 100 degrees (range, 100 degrees -115 degrees ) and postoperative ROM returned to pre-injury levels.Composite fixation can be a helpful adjunct in the treatment of this challenging problem. PMID- 30296317 TI - Reverse Total Shoulder Arthroplasty: Indications and Techniques Across the World. AB - Reverse total shoulder arthroplasty (RTSA) is a common treatment for rotator cuff tear arthropathy. We performed a systematic review of all the RTSA literature to answer if we are treating the same patients with RTSA, across the world. A systematic review was registered with PROSPERO, the international prospective register of systematic reviews, and performed with Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines using 3 publicly available free databases. Therapeutic clinical outcome investigations reporting RTSA outcomes with levels of evidence I to IV were eligible for inclusion. All study, subject, and surgical technique demographics were analyzed and compared between continents. Statistical comparisons were conducted using linear regression, analysis of variance (ANOVA), Fisher's exact test, and Pearson's chi square test. There were 103 studies included in the analysis (8973 patients; 62% female; mean age, 70.9 +/- 6.7 years; mean length of follow-up, 34.3 +/- 19.3 months) that had a low Modified Coleman Methodology Score (MCMS) (mean, 36.9 +/- 8.7: poor). Most patients (60.8%) underwent RTSA for a diagnosis of rotator cuff arthropathy, whereas 1% underwent RTSA for fracture; indications varied by continent. There were no consistent reports of preopeartive or postoperative scores from studies in any region. Studies from North America reported significantly higher postoperative external rotation (34.1 degrees +/- 13.3 degrees vs 19.3 degrees +/- 8.9 degrees ) (P < .001) and a greater change in flexion (69.0 degrees +/- 24.5 degrees vs 56.3 degrees +/- 11.3 degrees ) (P = .004) compared with studies from Europe. North America had the greatest total number of publications followed by Europe. The total yearly number of publications increased each year (P < .001), whereas the MCMS decreased each year (P = .037). The quantity, but not the quality of RTSA studies is increasing. Indications for RTSA varied by continent, although most patients underwent RTSA for rotator cuff arthropathy. The majority of patients undergoing RTSA are female over the age of 60 years for a diagnosis of rotator cuff arthropathy with pseudoparalysis. PMID- 30296322 TI - The Flint Lock: A Novel Technique in Total Knee Arthroplasty Closure. AB - Conventional interrupted sutures are traditionally used in extensor mechanism closure during total knee arthroplasty (TKA). In recent years, barbed suture has been introduced with the proposed benefits of decreased closure time and a watertight seal that is superior to interrupted sutures. Complication rates using barbed sutures and conventional interrupted sutures are similar. We propose a novel closure technique known as the Flint Lock, which is a double continuous interlocking stitch. The Flint Lock provides a quick and efficient closure to the extensor mechanism in TKA. In addition, similar to barbed suture, the Flint Lock should provide a superior watertight seal. It utilizes relatively inexpensive and readily available materials.

PMID- 30296319 TI - The Cold, Hard Facts of Cryotherapy in Orthopedics. AB - Cryotherapy is the use of the anti-inflammatory and analgesic properties of ice to facilitate healing. Cryotherapy mediates these salutatory effects by reducing blood flow to the site of injury, down-regulating the production of inflammatory and pain-inducing prostaglandins, and diminishing the conductive ability of nerve endings. It is commonly used postoperatively in orthopedics to decrease analgesic requirements and blood loss as well as to increase range of motion, despite limited literature on its ability to produce such therapeutic effects in clinical practice. This article examines the available literature and the scientific evidence for the use and efficacy of cryotherapy in post-surgical orthopedic patients. It also reviews the potential pitfalls associated with improper use. Overall, this review seeks to provide insight into when, or whether, cryotherapy is appropriate for orthopedic patients during surgical recovery. PMID- 30296321 TI - The Effect of Insurance Type on Patient Access to Ankle Fracture Care Under the Affordable Care Act. AB - The purpose of this study is to assess the effect of insurance type (Medicaid, Medicare, private insurance) on the ability for patients with operative ankle fractures to access orthopedic traumatologists. The research team called 245 board-certified orthopedic surgeons specializing in orthopedic trauma within 8 representative states. The caller requested an appointment for their fictitious mother in order to be evaluated for an ankle fracture which was previously evaluated by her primary care physician and believed to require surgery. Each office was called 3 times to assess the response for each insurance type. For each call, information was documented regarding whether the patient was able to receive an appointment and the barriers the patient confronted to receive an appointment. Overall, 35.7% of offices scheduled an appointment for a patient with Medicaid, in comparison to 81.4%and 88.6% for Medicare and BlueCross, respectively (P < .0001). Medicaid patients confronted more barriers for receiving appointments. There was no statistically significant difference in access for Medicaid patients in states that had expanded Medicaid eligibility vs states that had not expanded Medicaid. Medicaid reimbursement for open reduction and internal fixation of an ankle fracture did not significantly correlate with appointment success rates or wait times. Despite the passage of the Affordable Care Act, patients with Medicaid have reduced access to orthopedic surgeons and more complex barriers to receiving appointments. A more robust strategy for increasing care-access for patients with Medicaid would be more equitable. PMID- 30296320 TI - The Effect of Age on the Benefits of Early Decompression for Cervical Spondylotic Myelopathy. AB - Cervical myelopathy is the most common cause of acquired spinal cord dysfunction in people aged >55 years. Advanced age and duration of symptoms have been implicated in the literature as negative prognostic indicators for postoperative functional improvement, but very few studies have evaluated the interaction of these factors. We retrospectively reviewed 125 patients who underwent surgery for cervical myelopathy. Patients were stratified according to age greater or less than 65 years and duration of symptoms of greater or less than 12 and 24 months. Functional outcomes were assessed using the Nurick score. Simple regression and multiple regression analyses were done, controlling for sex, preoperative Nurick score, surgical approach, smoking status, diabetes status, prior surgery, number of levels fused, ethanol use, and signal change on preoperative magnetic resonance imaging. The average change in Nurick score in all patients was 1.36, with a significant difference between patients with symptoms for <24 months and those with symptoms for >24 months (1.54 vs 0.98, P = .03). Multiple regression analysis revealed that older patients had a significant difference at 24 months (1.69 vs 1.25, P = .01), whereas younger patients showed slightly lower improvement overall and a change in Nurick score at both thresholds that was statistically nonsignificant. PMID- 30296318 TI - Subcutaneous Ulnar Nerve Transposition Using Osborne's Ligament as a Ligamentodermal or Ligamentofascial Sling. AB - The ulnar nerve is most commonly compressed at the elbow in the cubital tunnel. Conservative and operative treatments have been applied for cubital tunnel syndrome. Surgical management options include decompression, medial epicondylectomy, and various anterior transposition techniques. We describe a novel technique of anterior transposition of the ulnar nerve by using Osborne's ligament as a sling to avoid subluxation. Osborne's ligament is incised posteriorly and medially on the olecranon to create a sling with 2 to 3 cm width. The sling is tailored to wrap around the ulnar nerve and attached to the flexor pronator fascia or dermis to create a smooth gliding surface without causing compression. Ten patients with cubital tunnel syndrome, established by physical examination findings and electromyography/nerve conduction studies underwent ulnar nerve transposition using this technique and were able to participate in a phone survey. The average follow-up was 15.6 months (range, 4-28 months). The average time to become subjectively "better" after surgery was 4.2 weeks. The pain intensity was reduced from an average of 7.5 preoperatively to <1, on a 10 point scale, at the time of the survey. All patients had symptomatic relief without any complication. The proposed technique using Osborne's ligament as a ligamentofascial or ligamentodermal sling offers a unique way of creating a non compressive sling with the component of the cubital tunnel itself and has an additional benefit of creating a smooth gliding surface for early return of function. PMID- 30296325 TI - Effect of NSAIDs on Pupil Diameter and Expression of Aqueous Humor Cytokines in FLACS Versus Conventional Phacoemulsification. AB - PURPOSE: To compare the concentrations of interleukin (IL) (IL-1b, IL-2, IL-4, IL 5, IL-6, IL-8, IL-10, IL-12p70), interferon (IFN)-gamma, tumor necrosis factor (TNF)-alpha, and TNF-beta in the aqueous humor of patients undergoing femtosecond laser-assisted cataract surgery (FLACS) and corneal mechanical paracentesis treated with two different topical nonsteroidal anti-inflammatory drugs (NSAIDs): bromfenac and indomethacin. METHODS: In this prospective, randomized controlled, single-center study, aqueous humor samples were obtained immediately after performing the femtosecond laser procedure or at the start of conventional phacoemulsification. Preoperatively, the FLACS groups were administered (once daily and four times daily, respectively) either topical bromfenac 0.09% (12 eyes) or indomethacin 0.1% (12 eyes). The corneal paracentesis bromfenac and indomethacin groups received the same regimen of instillation of NSAIDs, respectively. Quantitative analysis of the expressed cytokines in the aqueous humor was performed using FlowCytomix FC 500 Pro 3.0 Software (Bender MedSystems GmbH, Vienna, Austria). RESULTS: The intraoperative pupil diameter was correlated with the expression of IL-6 after the femtosecond laser procedure in the FLACS indomethacin group (r = -0.53; P = .07). A significant difference in mean pupillary size was detected between the FLACS bromfenac and indomethacin groups at the aspiration/irrigation time point (0.53 +/- 0.26 mm) and at the end of surgery (0.68 +/- 0.37 mm). Progressive pupillary constriction was observed in the indomethacin and bromfenac groups. CONCLUSIONS: A smaller expression of IL-6 to the overall cytokine network value was observed in cases receiving preoperative bromfenac 0.09%, explaining improved maintenance of intraoperative mydriasis.

PMID- 30296324 TI - Timing of Adverse Events Following Geriatric Hip Fracture Surgery: A Study of 19,873 Patients in the American College of Surgeons National Surgical Quality Improvement Program. AB - This study uses a prospective surgical registry to characterize the timing of 10 postoperative adverse events following geriatric hip fracture surgery. There were 19,873 patients identified who were >=70 years undergoing surgery for hip fracture as part of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). The median postoperative day of diagnosis (and interquartile range) for myocardial infarction was 3 (1-5), cardiac arrest requiring cardiopulmonary resuscitation 3 (0-8), stroke 3 (1-10), pneumonia 4 (2 10), pulmonary embolism 4 (2-11), urinary tract infection 7 (2-13), deep vein thrombosis 9 (4-16), sepsis 9 (4-18), mortality 11 (6-19), and surgical site infection 16 (11-22). For the earliest diagnosed adverse events, the rate of adverse events had diminished by postoperative day 30. For the later diagnosed adverse events, the rate of adverse events remained high at postoperative day 30. Findings help to enable more targeted clinical surveillance, inform patient counseling, and determine the duration of follow-up required to study specific adverse events effectively. Orthopedic surgeons should have the lowest threshold for testing for each adverse event during the time period of greatest risk. PMID- 30296323 TI - Time-to-Surgery for Definitive Fixation of Hip Fractures: A Look at Outcomes Based Upon Delay. AB - The morbidity and mortality after hip fracture in the elderly are influenced by non-modifiable comorbidities. Time-to-surgery is a modifiable factor that may play a role in postoperative morbidity. This study investigates the outcomes and complications in the elderly hip fracture surgery as a function of time-to surgery. Using the American College of Surgeons-National Surgical Quality Improvement Program data from 2011 to 2012, a study population was generated using the Current Procedural Terminology codes for percutaneous or open treatment of femoral neck fractures (27235, 27236) and fixation with a screw and side plate or intramedullary fixation (27244, 27245) for peritrochanteric fractures. Three time-to-surgery groups (<24 hours to surgical intervention, 24-48 hours, and >48 hours) were created and matched for surgery type, sex, age, and American Society of Anesthesiologists class. Time-to-surgery was then studied for its effect on the post-surgical outcomes using the adjusted regression modeling. A study population of 6036 hip fractures was created, and 2012 patients were assigned to each matched time-to-surgery group. The unadjusted models showed that the earlier surgical intervention groups (<24 hours and 24-48 hours) exhibited a lower overall complication rate (P = .034) compared with the group waiting for surgery >48 hours. The unadjusted mortality rates increased with delay to surgical intervention (P = .039). Time-to-surgery caused no effect on the return to the operating room rate (P = .554) nor readmission rate (P = .285). Compared with other time-to-surgeries, the time-to-surgery of >48 hours was associated with prolonged total hospital length of stay (10.9 days) (P < .001) and a longer surgery-to-discharge time (hazard ratio, 95% confidence interval: 0.74, 0.69 0.79) (P < .001). Adjusted analyses showed no time-to-surgery related difference in complications (P = .143) but presented an increase in the total length of stay (P < .001) and surgery-to-discharge time (P < .001). Timeliness of surgical intervention in a comorbidity-adjusted population of elderly hip fracture patients causes no effect on the overall complications, readmissions, nor 30-day mortality. However, time-to-surgery of >48 hours is associated with costly increase in the total length of stay, including an increased post-surgery-to discharge time. PMID- 30296326 TI - Implantable Collamer Lens(r) for Management of Pseudophakic Ametropia in Eyes With a Spectrum of Previous Corneal Surgery. AB - PURPOSE: To assess the visual outcomes, predictability, and safety of the Implantable Collamer Lens (ICL) (STAAR Surgical, Inc., Monrovia, CA) for the management of residual pseudophakic refractive error. METHODS: Forty-nine pseudophakic eyes of 40 patients in which myopic, hyperopic, or toric ICLs were implanted were retrospectively analyzed. Twenty-nine eyes had been implanted with a monofocal intraocular lens (IOL) and 20 eyes had a multifocal IOL. All IOLs were implanted in the capsular bag. Of the 49 eyes included, 6 had residual refractive error after phacoemulsification without corneal pathology or surgical alteration (virgin cornea group), 12 had LASIK or photorefractive keratectomy (PRK) (excimer laser group), 8 had radial keratotomy, 5 had intrastromal corneal ring segments (ICRS) implantation, 11 had penetrating keratoplasty, and 7 had deep anterior lamellar keratoplasty (DALK). Uncorrected and corrected (CDVA) distance visual acuity and manifest refraction were evaluated. RESULTS: The efficacy/safety indices were 0.92/1.10, 0.98/1.13, 1.04/1.11, 0.90/1.13, 0.79/1.17, and 0.71/1.23 for the virgin cornea, excimer laser, radial keratotomy, ICRS, penetrating keratoplasty, and DALK groups, respectively. No eye lost one or more lines of CDVA. The virgin cornea, excimer laser, and radial keratotomy groups showed better predictability and accuracy, with 96.2% spherical equivalent within +/-1.00 diopters (D). The ICRS, penetrating keratoplasty, and DALK groups demonstrated approximately 50% spherical equivalent within +/-1.00 D. There were no intraoperative or postoperative complications. CONCLUSIONS: Good refractive outcomes and a strong safety record support the use of the ICL for the correction of residual refractive error in pseudophakic eyes with previous corneal surgery.

AB - PURPOSE: To compare posterior corneal features and their discriminating power for differentiating normal corneas from subclinical keratoconus using the Placido dual-Scheimpflug analyzer. METHODS: Patients were retrospectively included in the study. The preoperative normal right eyes of 79 patients imaged with a Placido dual-Scheimpflug system and with a stable postoperative LASIK follow-up of a minimum of 36 months were included in the normal group and were compared to 39 contralateral topographically normal eyes with clinically evident keratoconus in the fellow eye. The posterior surface variables measured were categorized according to the feature of the corneal shape they were characterizing (curvature, elevation, asymmetry, and eccentricity) and compared between the two groups using the Student's two-sample t test. The discriminating ability of the posterior surface variables was compared by receiver operator characteristics curves. RESULTS: Variables that related to asymmetry and elevation of the posterior surface were statistically significantly different between groups (P < .05), whereas eccentricity and curvature-related parameters were not. Receiver operator characteristics curves analysis showed that the maximum posterior elevation over the best-fit toric and aspheric surface reference shape had the highest discriminating ability for distinguishing normal corneas from subclinical keratoconus, with an area under the curve of 0.877, followed by the asphericity asymmetry index, with an area under the curve of 0.871, and posterior inferior superior value, with an area under the curve of 0.851. CONCLUSIONS: Posterior cornea measured with a dual-Scheimpflug analyzer provides useful parameters for differentiating normal corneas from subclinical keratoconus. Of the posterior surface parameters, asymmetry and elevation seem to be the most sensitive shape modifications for differentiating both populations. [J Refract Surg. 2018;34(10):664-670.]. PMID- 30296328 TI - Outcomes for Mixed Cylinder LASIK With the MEL 90(r) Excimer Laser. AB - PURPOSE: To report the outcomes of LASIK for mixed cylinder using the Triple-A ablation profile with the MEL 90 excimer laser (Carl Zeiss Meditec, Jena, Germany). METHODS: This was a retrospective analysis of all eyes treated by LASIK for mixed cylinder using the Triple-A ablation profile with the MEL 90 laser between July 2013 and October 2016. Patients were observed for 1 year after surgery. Standard outcomes analysis and vector analysis by the Alpins method were performed. RESULTS: The database review identified 105 eyes (82 patients) treated by LASIK for mixed cylinder using the MEL 90 laser. Mean age was 40 +/- 11 years (range: 18 to 65 years). Mean attempted spherical equivalent was +0.30 +/- 0.90 diopters (D) (range: -2.30 to +1.75 D). Mean cylinder was -2.93 +/- 1.47 D (range: -0.75 to -7.00 D). Preoperative corrected distance visual acuity (CDVA) was 20/20 or better in 81% of eyes. Postoperative uncorrected distance visual acuity was 20/20 or better in 69% and 20/25 or better in 86% of eyes. Mean postoperative spherical equivalent relative to the intended target was -0.21 +/- 0.38 D (range: -1.25 to +1.13 D), with 83% within +/-0.50 D. Mean postoperative cylinder was -0.57 +/- 0.41 D (range: 0.00 to -1.75 D). Geometric mean was 1.12 for the correction index and 0.25 for the index of success. For angle of error, the arithmetic mean was -0.6 degrees +/- 4.2 degrees (range: -13.5 degrees to 9.5 degrees ) and the absolute mean was 2.9 degrees +/- 3.0 degrees (range: 0.0 degrees to 13.5 degrees ). There was loss of one line of CDVA in 3% of eyes and no eyes lost two or more lines CDVA. There was a small increase in contrast sensitivity after surgery at 3, 6, 12, and 18 cycles per degree (P < .05). CONCLUSIONS: One-year outcomes of LASIK using the MEL 90 laser for mixed cylinder up to -7.00 D demonstrated excellent efficacy, safety, and predictability. Vector analysis found a 12% overcorrection in magnitude of refractive cylinder. Given the high accuracy for angle of error, a nomogram could be applied to reduce the over-correction and further improve the uncorrected distance visual acuity outcomes.

AB - PURPOSE: To report long-term outcomes of sequential customized therapeutic keratectomy for Reis-Bucklers' corneal dystrophy. METHODS: This was a retrospective review of 14 eyes of 8 patients with Reis-Bucklers' corneal dystrophy that underwent surgical peeling with a spatula of the epithelium and subepithelial membrane present in Reis-Bucklers' corneal dystrophy, with subsequent sequential customized therapeutic keratectomy featuring a multi-step approach with sequential, repeated customized excimer laser photoablations alternating with repeat intraoperative topographies to monitor and progressively reduce corneal irregularities. RESULTS: At the last follow-up of 5.09 +/- 4.67 years (range: 0.29 to 12.87 years), mean corrected distance visual acuity improved from 20/50 (range: 20/630 to 20/30) to 20/25 (range: 20/20 to 20/40) (P < .01), whereas mean refraction changed from -0.29 +/- 1.91 diopters (D) sphere and -0.75 +/- 0.81 D cylinder preoperatively to 1.25 +/- 2.10 D sphere and -1.08 +/- 0.53 D cylinder postoperatively. Mean central keratometry values changed minimally from 42.67 +/- 2.26 D preoperatively to 42.65 +/- 2.30 D postoperatively. Coma significantly decreased from 0.60 +/- 0.40 to 0.35 +/- 0.28 MUm (P < .05), whereas total higher order aberrations, spherical aberration, and trefoil remained stable. No patient underwent corneal transplantation. Disease recurrence required re-treatment using the same protocol in 14.28% of eyes (n = 2) for a mean of 5.86 +/- 0.31 years (range: 5.64 to 6.08 years) after initial surgery. CONCLUSIONS: Five years after sequential customized therapeutic keratectomy, most eyes with Reis-Bucklers' corneal dystrophy showed improved visual acuity, stable refraction, and improved or stable higher order aberrations.

AB - PURPOSE: To evaluate the outcomes of simultaneous and sequential corneal crosslinking (CXL) and excimer laser surface ablation protocols in keratoconus. METHODS: A literature review was conducted using MEDLINE. The studies were divided into three groups: the sequential group included studies with CXL followed by excimer laser surface ablation later, the simultaneous group included simultaneous excimer laser surface ablation and CXL, and the no CXL group included excimer laser surface ablation only with no CXL. The data on change in logMAR uncorrected distance visual acuity (UDVA), spectacle corrected distance visual acuity (CDVA), change in spherical equivalent (SE) and refractive astigmatism, change in maximum keratometry (Kmax), complications, and safety and efficacy indices were presented for the latest follow-up visits in all groups. RESULTS: Twenty-one studies (3 = sequential; 11 = simultaneous, 7 = no CXL) were included. UDVA improved in all groups. CDVA improved more in the sequential group. SE change was greatest in the no CXL group and the refractive astigmatism reduced comparably in the sequential and no CXL groups but less in the simultaneous group. Kmax reduced in all groups. Only the sequential group showed no progression. Corneal haze was reported in 100%, 54.5%, and 57.1% studies, respectively. Safety and efficacy indices were 1.96 and 1.58, 1.41 +/- 0.32 and 0.91 +/- 0.41, and 1 and 0.82, respectively. CONCLUSIONS: The sequential group showed greater improvement in CDVA, SE, and refractive astigmatism. Corneal haze was frequently reported in all protocols. Safety and efficacy indices were highest when CXL was performed before excimer laser and least when excimer laser was performed alone without CXL. [J Refract Surg. 2018;34(10):690-696.]. PMID- 30296331 TI - Presbyopic Excimer Laser Ablation: A Review. AB - PURPOSE: To provide an overview of the efficacy and safety of available presbyopic excimer laser ablation profiles. METHODS: Literature review. RESULTS: Monovision with excimer laser traditionally applies near correction to the non dominant eye. Different excimer laser presbyopic approaches include the increase in depth of focus, through the controlled change of spherical aberration or asphericity, or multifocal ablation patterns with central or peripheral near vision zones. The studies investigating different excimer laser ablation patterns applied in previously myopic eyes revealed high levels of efficacy with all ablation profiles (between 68% and 99% achieving binocular uncorrected distance visual acuity [UDVA] of 20/25 or better, and between 70% and 100% achieving uncorrected near visual acuity [UNVA] presenting J3 or better). In hypermetropic eyes, most of the studies revealed high levels of efficacy with different platforms (between 78% and 100% achieving binocular UDVA of 20/25 or better and between 70% and 100% achieving UNVA presenting J3 or better). Loss of two or more lines of corrected distance visual acuity varied between 0% and 10% in the myopic eyes and between 0% and 14% in the hyperopic eyes. CONCLUSIONS: There is evidence that excimer laser presbyopic strategies accomplish spectacle independence at reasonable levels. There are reliable and safe options for both myopic and hyperopic eyes with satisfactory outcomes regarding near and distance vision. [J Refract Surg. 2018;34(10):698-710.].

PMID- 30296333 TI - The postnatal development of ultrasonic vocalization-associated breathing is altered in glycine transporter 2-deficient mice. AB - KEY POINTS: Newborn mice produce ultrasonic vocalization to communicate with their mother. The neuronal glycine transporter (GlyT2) is required for efficient loading of synaptic vesicles in glycinergic neurons. Mice lacking GlyT2 develop a phenotype that resembles human hyperekplexia and the mice die in the second postnatal week. In the present study, we show that GlyT2-knockout mice do not acquire adult ultrasonic vocalization-associated breathing patterns. Despite the strong impairment of glycinergic inhibition, they can produce sufficient expiratory airflow to produce ultrasonic vocalization. Because mouse ultrasonic vocalization is a valuable read-out in translational research, these data are highly relevant for a broad range of research fields. ABSTRACT: Mouse models are instrumental with respect to determining the genetic basis and neural foundations of breathing regulation. To test the hypothesis that glycinergic synaptic inhibition is required for normal breathing and proper post-inspiratory activity, we analysed breathing and ultrasonic vocalization (USV) patterns in neonatal mice lacking the neuronal glycine transporter (GlyT2). GlyT2-knockout (KO) mice have a profound reduction of glycinergic synaptic currents already at birth, develop a severe motor phenotype and survive only until the second postnatal week. At this stage, GlyT2-KO mice are smaller, have a reduced respiratory rate and still display a neonatal breathing pattern with active expiration for the production of USV. By contrast, wild-type mice acquire different USV-associated breathing patterns that depend on post-inspiratory control of air flow. Nonetheless, USVs per se remain largely indistinguishable between both genotypes. We conclude that GlyT2-KO mice, despite the strong impairment of glycinergic inhibition, can produce sufficient expiratory airflow to produce ultrasonic vocalization. PMID- 30296334 TI - Periodontal disease increases the risk for onset of systemic comorbidities in dental hospital attendees: An 18-year retrospective cohort study. AB - BACKGROUND: Periodontal disease closely links to various systemic diseases. This l8-year retrospective cohort study investigated whether poor periodontal condition may increase the risk for onset of systemic comorbidities. METHODS: A total of 488 individual dental folders from 17 400 dental hospital attendees registered from 1996 to 1998 were randomly selected, and these participants were free of diabetes, cardiovascular disease, chronic obstructive pulmonary disease, cancer, stroke, cognitive impairment, hypertension, and dyslipidemia in the Clinical Management System. The records of periodontal examination and orthopantomogram on the first registration were obtained, and full-mouth bone level (BL) was measured. Onsets of the eight comorbidities concerned above until 2016 were retrieved from the system. RESULTS: The participants with worse periodontal status on their first registration had significantly higher numbers of the eight comorbidities/mortality during the 18-year follow-ups than their counterparts (P < 0.05). BL presented as bone loss/age was independently correlated to the comorbidity profiles in two multivariate models (0 to 1 versus >=2; 0 to 2 versus >=3) after adjusting for age and sex (odds ratio [OR] = 1.87; OR = 2.18, P < 0.05), highlighting that the individuals with more bone resorption exhibited a greater number of the comorbidities as compared with their counterparts. Moreover, those with onsets of more comorbidities showed worse periodontal conditions according to four parameters employed (community periodontal index, BL, bone loss/age and number of remaining teeth) (P < 0.05). CONCLUSION: Within the limitations of this 18-year retrospective cohort study, our findings provide the first evidence that periodontal disease experience to some extent reflects the host susceptibility to onset of common systemic comorbidities. Further studies with larger sample sizes and appropriate adjustment of critical confounders are highly warranted to substantiate the current observation. PMID- 30296335 TI - An Unusually High Cocaine Blood Concentration in an Impaired Driving Investigation. AB - Cocaine is an illicit drug frequently encountered by forensic practitioners in driving under the influence of drugs (DUID) casework. Whole blood collected from a suspected drugged driver was found to contain 3.000 mg/L cocaine, 1.600 mg/L benzoylecgonine, and 0.260 mg/L methamphetamine. The high concentration of cocaine, while common in overdose death investigations, is unusual for an impaired driving case. Information from the officer revealed that the motorist swallowed cocaine during the traffic stop. Although a cocaine DUID charge could not be pursued, the blood methamphetamine concentration exceeded the State of Nevada "per se" limit for operating a motor vehicle. The motorist was successfully prosecuted for DUID based on his admission of using methamphetamine prior to driving and the blood methamphetamine result. This case highlights the importance of considering case history when interpreting laboratory results and the application of jurisdictional statutes as an approach to prosecuting suspected drug-impaired drivers. PMID- 30296336 TI - Effect of Relocation on Neuropsychiatric Symptoms in Elderly Adults Living in Long-Term Care. AB - OBJECTIVES: To determine the evolution of behavioral and psychiatric symptoms of dementia (BPSD) in nursing home (NH) residents after an environmental change through a relocation to a more architecturally suitable facility, while conserving the same medical staff. DESIGN: Prospective, single arm study. SETTING: Long-term care unit. PARTICIPANTS: NH residents (N=116; median age 82.3, range 75.5-89.2; median Neuropsychiatric Inventory for the Nursing Home (NPI/NH) score 22, range 11-34.5; 66.3% female), of whom 102 lived in regular units and 14 in specialized care units (SCUs). MEASUREMENTS: Neuropsychiatric symptoms were evaluated as part of a comprehensive geriatric assessment for each resident 1 week before the relocation and 3 times after the relocation (1, 4, 12 weeks) using the NPI/NH. RESULTS: A mixed-effect linear model found no significant change in global NPI/NH score in the regular unit and a significant decrease in overall NPI/NH score 4 weeks after relocation in the SCUs (beta-coefficient for time by SCU=-11.5, 95% confidence interval (CI)=-17.9-5.2, p < .001), reaching a total decrease of 13 points by 12 weeks after relocation (beta-coefficient for time by SCU=-12.8, 95% CI=-19.1-6.4, p < .001). A statistically significant decrease of 3 points for disinhibition, apathy, and agitation accompanied the NPI/NH score in the secured unit. An increase of 3 points in aberrant motor behavior was seen by 12 weeks after relocation in the SCU. CONCLUSION: Relocation to an architecturally different facility significantly reduced BPSD of NH residents 1 month after relocation. J Am Geriatr Soc 66:2183-2187, 2018. PMID- 30296337 TI - Cancer and Aging: Reflections for Elders (CARE): A pilot randomized controlled trial of a psychotherapy intervention for older adults with cancer. AB - OBJECTIVE: Cancer and Aging: Reflections for Elders (CARE) is a novel, telephone delivered intervention designed to alleviate distress in older cancer patients. This pilot randomized controlled trial tested the feasibility and initial efficacy of CARE, drawing from age-appropriate developmental themes and well established coping theory. METHOD: Eligible patients were >=70 years old; >=6 months post-diagnosis of lung, prostate, breast, lymphoma, or gynecological cancer; on active cancer treatment or within 6 months of ending cancer treatment; and had elevated scores on the Distress Thermometer (>=4) or Hospital Anxiety and Depression Scale (>=6). Participants completed five sessions of psychotherapy over 7 weeks with assessments at study entry, post-intervention, and 2 months post-intervention. Primary outcomes were feasibility and initial efficacy on anxiety and depression; secondary outcomes included demoralization, coping, loneliness, and spiritual well-being. RESULTS: Fifty-nine participants were randomized to either the CARE arm (n = 31) or the enhanced Social Work Control arm (n = 28). The intervention was feasible and tolerable, meeting a priori criteria for rates of eligibility, acceptance, retention, assessment, and treatment fidelity. Upon completion of the intervention, participants in the CARE arm demonstrated lower mean depression scores (d = 0.58 [CI: 0.04-1.12], P = 0.01) and trended towards increased coping-planning (d = 0.30 [CI: -0.83 to 0.24], P = 0.18). Promising trends in anxiety (d = 0.41 [CI: -0.17 to 0.98], P = 0.10) emerged at 2 months post-intervention; effects for coping-planning dissipated. CONCLUSION: These pilot data suggest the CARE intervention is feasibly delivered, potentially impacts important psychosocial variables, and is accessible for older, frail patients with cancer. Future research will evaluate this intervention on a larger scale. PMID- 30296338 TI - JAG2 signaling induces differentiation of CD14+ monocytes into Langerhans cell histiocytosis-like cells. AB - Langerhans cell histiocytosis (LCH) is a MAPK pathway-driven disease characterized by the accumulation of CD1a+ langerin+ cells of unknown origin. We have previously reported that the Notch signaling pathway is active in LCH lesions and that the Notch ligand Jagged2 (JAG2) induces CD1a and langerin expression in monocytes in vitro. Here we show that Notch signaling induces monocytes to acquire an LCH gene signature and that Notch inhibition suppresses the LCH phenotype. In contrast, while also CD1c+ dendritic cells or IL-4 stimulated CD14+ monocytes acquire CD1a and langerin positivity in culture, their gene expression profiles and surface phenotypes are more different from primary LCH cells. We propose a model where CD14+ monocytes serve as LCH cell precursor and JAG2-mediated activation of the Notch signaling pathway initiates a differentiation of monocytes toward LCH cells in selected niches and thereby contributes to LCH pathogenesis. PMID- 30296339 TI - Status of Mandibular Third Molar Development as Evidence in Legal Age Threshold Cases. AB - The completion of the third molar roots has played an important role in ascertaining whether individuals may be at or over a legal threshold of age, often taken as 18 years. This study demonstrates that root apex completion in the third molar is relatively uninformative regarding the threshold of age 18 years in a sample of 1184 males, where mean age-of-attainment of root apex completion for third mandibular molars is about 19.4 years. This paper also considers the legal age threshold problem for cases where the third mandibular molar is not completely formed, and outlines the use of parametric models and Bayes' factors to evaluate dental evidence in statistically appropriate ways. It attempts to resolve confusion over age-within-stage versus age-of-attainment, likelihood ratios versus other diagnostic tests, and prior odds for a case versus the prior density for an age distribution. PMID- 30296340 TI - Modeling Undetected Live Poliovirus Circulation After Apparent Interruption of Transmission: Pakistan and Afghanistan. AB - Since most poliovirus infections occur with no paralytic symptoms, the possibility of silent circulation complicates the confirmation of the end of poliovirus transmission. Based on empirical field experience and theoretical modeling results, the Global Polio Eradication Initiative identified three years without observing paralytic cases from wild polioviruses with good acute flaccid paralysis surveillance as an indication of sufficient confidence that poliovirus circulation stopped. The complexities of real populations and the imperfect nature of real surveillance systems subsequently demonstrated the importance of specific modeling for areas at high risk of undetected circulation, resulting in varying periods of time required to obtain the same level of confidence about no undetected circulation. Using a poliovirus transmission model that accounts for variability in transmissibility and neurovirulence for different poliovirus serotypes and characterizes country-specific factors (e.g., vaccination and surveillance activities, demographics) related to wild and vaccine-derived poliovirus transmission in Pakistan and Afghanistan, we consider the probability of undetected poliovirus circulation for those countries once apparent die-out occurs (i.e., in the absence of any epidemiological signals). We find that gaps in poliovirus surveillance or reaching elimination with borderline sufficient population immunity could significantly increase the time to reach high confidence about interruption of live poliovirus transmission, such that the path taken to achieve and maintain poliovirus elimination matters. Pakistan and Afghanistan will need to sustain high-quality surveillance for polioviruses after apparent interruption of transmission and recognize that as efforts to identify cases or circulating live polioviruses decrease, the risks of undetected circulation increase and significantly delay the global polio endgame.

AB - The liver owns an extraordinary regenerative capacity to compensate functional mass loss after acute cytotoxic injury or surgical resection. Hepatic mass restoration following hepatocellular or cholangiocellular injury is commonly mediated by the proliferation and replenishment of the existing differentiated hepatocytes and biliary epithelial cells (BECs or cholangiocytes), respectively.

PMID- 30296342 TI - Postoperative Delirium in Individuals Undergoing Transcatheter Aortic Valve Replacement: A Systematic Review and Meta-Analysis. AB - OBJECTIVES: To evaluate the incidence of in-hospital postoperative delirium (IHPOD) after transcatheter aortic valve replacement (TAVR). DESIGN: Systematic review and meta-analysis. SETTING: Elective procedures PARTICIPANTS: Individuals undergoing TAVR. MEASUREMENTS: A literature search was conducted in PubMed, Embase, BioMedCentral, Google Scholar, and the Cochrane Central Register of Controlled Trials (up to December 2017). All observational studies reporting the incidence of IHPOD after TAVR (sample size > 25) were included in our meta analysis. The reported incidence rates were weighted to obtain a pooled estimate rate with 95% confidence interval (CI). RESULTS: Of 96 potentially relevant articles, 31 with a total of 32,389 individuals who underwent TAVR were included in the meta-analysis. The crude incidence of IHPOD after TAVR ranged from 0% to 44.6% in included studies, with a pooled estimate rate of 8.1% (95% CI=6.7-9.4%); heterogeneity was high (Q = 449; I = 93%; pheterogeneity < .001). The pooled estimate rate of IHPOD was 7.2% (95% CI=5.4-9.1%) after transfemoral (TF) TAVR and 21.4% (95% CI=10.3-32.5%) after non-TF TAVR. CONCLUSION: Delirium occurs frequently after TAVR and is more common after non-TF than TF procedures. Recommendations are made with the aim of standardizing future research to reduce heterogeneity between studies on this important healthcare problem. PMID- 30296343 TI - Fluoxetine-induced Stevens-Johnson syndrome and liver injury. AB - WHAT IS KNOWN AND OBJECTIVE: Drug-induced liver injuries (DILI) are overall rare and often associated with use of medications. Medications are also the most common aetiology of Stevens-Johnson syndrome (SJS), but SJS is seldom seen concomitantly with liver injury. Many common drugs can cause either one of these conditions; however, there are no reported cases of concomitant DILI and SJS secondary to fluoxetine. CASE SUMMARY: A 41-year-old female presented with a skin rash and abnormal liver function tests after the recent initiation of fluoxetine. Skin and liver biopsies showed features of SJS and DILI, respectively. Fluoxetine was stopped, following which there was improvement in her liver function tests and skin rash, without progression to fulminant hepatic failure. WHAT IS NEW AND CONCLUSION: Commonly used and safe pharmaceuticals such as fluoxetine have the potential for serious adverse events affecting the skin and liver. PMID- 30296344 TI - A Preliminary Investigation into the Accuracy of 3D Modeling and 3D Printing in Forensic Anthropology Evidence Reconstruction. AB - There is currently no published empirical evidence-base demonstrating 3D printing to be an accurate and reliable tool in forensic anthropology, despite 3D printed replicas being exhibited as demonstrative evidence in court. In this study, human bones (n = 3) scanned using computed tomography were reconstructed as virtual 3D models (n = 6), and 3D printed using six commercially available printers, with osteometric data recorded at each stage. Virtual models and 3D prints were on average accurate to the source bones, with mean differences from -0.4 to 1.2 mm ( 0.4% to 12.0%). Interobserver differences ranged from -5.1 to 0.7 mm (-5.3% to 0.7%). Reconstruction and modeling parameters influenced accuracy, and prints produced using selective laser sintering (SLS) were most consistently accurate. This preliminary investigation into virtual modeling and 3D printer capability provides a novel insight into the accuracy of 3D printing osteological samples and begins to establish an evidence-base for validating 3D printed bones as demonstrative evidence. PMID- 30296345 TI - Mapping Socioeconomic Exposure for Flood Risk Assessment in Italy. AB - Detailed spatial representation of socioeconomic exposure and the related vulnerability to natural hazards has the potential to improve the quality and reliability of risk assessment outputs. We apply a spatially weighted dasymetric approach based on multiple ancillary data to downscale important socioeconomic variables and produce a grid data set for Italy that contains multilayered information about physical exposure, population, gross domestic product, and social vulnerability. We test the performances of our dasymetric approach compared to other spatial interpolation methods. Next, we combine the grid data set with flood hazard estimates to exemplify an application for the purpose of risk assessment. PMID- 30296346 TI - Do sexual calls in female black capuchin monkeys (Sapajus nigritus) vary with fertility? An acoustic analysis. AB - Females across a range of animal taxa produce vocalizations and signals uniquely associated with periods of mating. While such signals may ultimately function to increase female attractivity to males, conflicting findings challenge the extent to which these signals co-vary in accordance with the probability of conception. Female black capuchin monkeys (Sapajus nigritus) display an elaborate repertoire of both vocal and visual components as part of their socio-sexual behavior, and previous analyses have shown that the rates of production of visual, but not vocal, components provide graded information on female ovulation. It remains possible, however, that the acoustic parameters of these sexual calls, rather than their rate of productions, co-vary with female fertility. To test this, we analyzed structural and temporal call parameters from estrous calls and post copulatory calls recorded over five consecutive mating seasons in 12 sexually mature females at Iguazu National Park, Argentina. Calls given during the fertile phase of the female ovarian cycle were compared with those given during the non fertile phase, as determined by profiles of female reproductive hormones. Similarly, within the fertile phase, we tested whether temporal or spectral acoustic parameters of calls gradually change with the approach of ovulation. We did not find any significant relationship between call parameters and the two measures of female fertility in either female estrous calls or post-copulatory calls. However, some differences between pre- and post-copulatory calls were apparent. Overall, our results indicate that sexual calls in black capuchin females do not provide precise information about the timing of ovulation, but may allow listeners to make probabilistic inferences about whether copulations have taken place. This, combined with previous findings, suggests that females in our study may use signals in different modalities to convey information about their fertility and sexual behavior with varying degrees of precision.

AB - Currently, the general synthesis of 5-aryl-phenanthridin-6-ones relies on the involvement of metal catalysis. Despite the urgent demand for green alternatives, avoiding synthetic routes that require transition metals for key roles is still challenging. Electrochemical efforts employing a constant potential protocol in divided cells revealed a possible alternative to the catalytic approach. A constant current protocol, undivided cells, and a remarkably low supporting electrolyte concentration enable a novel access to N-aryl-phenanthridin-6-ones by anodic N,C bond formation using directly generated amidyl radicals. Easy accessible starting materials, a broad scope of applicable functional groups, good yields, and a very simple set-up are the benefits of this sustainable method.

AB - Despite a well-developed and growing body of work in Cu catalysis, the potential of Cu to serve as a photocatalyst remains underexplored. Reported herein is the first example of visible-light-induced Cu-catalyzed decarboxylative C(sp3 )-H alkylation of glycine for preparing alpha-alkylated unnatural alpha-amino acids. It merits mentioning that the mild conditions and the good functional-group tolerance allow the modification of peptides using this method. The mechanistic studies revealed that a radical-radical coupling pathway is involved in the reaction. PMID- 30296350 TI - Three-dimensional transesophageal echocardiography is an attractive alternative to cardiac multi-detector computed tomography for aortic annular sizing: Systematic review and meta-analysis. AB - BACKGROUND: Cardiac imaging is the cornerstone of the pretranscatheter aortic valve replacement (TAVR) assessment. Multi-detector computed tomography (MDCT) is considered the conventional imaging modality. However, there is still no definitive gold standard. Targeted cohort of inoperable high-risk patients with underlying comorbidities, particularly renal impairment, makes apparent the need for MDCT alternative. We aimed to demonstrate the correlation extent between MDCT and three-dimensional transesophageal echocardiography (3DTEE) aortic annular area measures and to answer the question: Is 3DTEE a good alternative to MDCT? METHODS: A systematic literature search and meta-analysis were conducted to evaluate the degree of correlation and agreement between 3DTEE and MDCT aortic annular sizing. A thorough assessment of EMBASE, PubMed, and Cochrane Central Register of Controlled Trials (CENTRAL) was performed. All studies comparing 3DTEE and MDCT in relation to aortic annular sizing were included. RESULTS: Thirteen studies were included (N = 1228 patients). A strong linear correlation was found between 3DTEE and MDCT measurements of aortic annulus area (r = 0.84, P < 0.001), mean perimeter (r = 0. 0.85, P < 0.001), and mean diameter (r = 0.80, P < 0.001). Bland-Altman plots revealed smaller mean 3DTEE values in comparison to MDCT for aortic annular area, the mean difference being -2.22 mm2 with 95% limits of agreement -12.79 to 8.36. CONCLUSION: Aortic annulus measurements obtained by 3DTEE demonstrated a high level of correlation with those evaluated by MDCT. This makes 3DTEE a feasible choice for aortic annulus assessment, with advantage of real time assessment, lack of contrast, and no radiation exposure.

PMID- 30296352 TI - Interband Electron Pairing for Superconductivity from the Breakdown of the Born Oppenheimer Approximation. AB - The origin of interband electron pairing, responsible for enhancing superconductivity, and the factors controlling its strength were examined. We show that interband electron pairing is a natural consequence of breaking down the Born-Oppenheimer approximation during electron-phonon interactions. Its strength is determined by the pair-state excitations around the Fermi surfaces that take place to form a superconducting state. Fermi surfaces favorable for the pairing were found, and the implications of this observation are discussed. PMID- 30296353 TI - Low dose isotretinoin for pigmented post-varicella scars. PMID- 30296354 TI - Study on bone quality in the human mandible-Alignment of biological apatite crystallites. AB - The importance of considering bone quality during oral implant treatment is increasingly being recognized. Assessment of bone quality in response to changes in the jaw bone is extremely important when planning treatment. The present study analyzed biological apatite (BAp) crystallites, a bone quality factor, in order to investigate crystallographic anisotropy in dentate and edentulous human mandibles. Using mandibular samples from Japanese adult cadavers, a region of interest was established comprising cortical bone in the central incisors. Samples were classified into five morphological categories based on the extent of bone resorption. Bone mineral density (BMD) was measured and diffraction intensity ratios were calculated using a microbeam X-ray diffraction system. While no differences were observed in BMD, differences were observed in BAp crystallite alignment between the measurement points. In the alveolar region, samples with residual alveolar bone showed strong alignment in the occlusal direction, while samples with marked alveolar bone resorption had preferential alignment in the mesiodistal direction. The present findings suggest that tooth loss and the extent of alveolar bone resorption affects bone quality in the mandible. (c) 2018 Wiley Periodicals, Inc. J. Biomed. Mater. Res. Part B: 2018. PMID- 30296355 TI - Autofluorescence lifetime imaging of cellular metabolism: Sensitivity toward cell density, pH, intracellular, and intercellular heterogeneity. AB - Autofluorescence imaging (AFI) has greatly accelerated in the last decade, way past its origins in detecting endogenous signals in biological tissues to identify differences between samples. There are many endogenous fluorescence sources of contrast but the most robust and widely utilized have been those associated with metabolism. The intrinsically fluorescent metabolic cofactors nicotinamide adenine dinucleotide (NAD+ /NADH) and flavin adenine dinucleotide (FAD/FADH2 ) have been utilized in a number of AFI applications including basic research, clinical, and pharmaceutical studies. Fluorescence lifetime imaging microscopy (FLIM) has emerged as one of the more powerful AFI tools for NADH and FAD characterization due to its unique ability to noninvasively detect metabolite bound and free states and quantitate cellular redox ratio. However, despite this widespread biological use, many standardization methods are still needed to extend FLIM-based AFI into a fully robust research and clinical diagnostic tools. FLIM is sensitive to a wide range of factors in the fluorophore microenvironment, and there are a number of analysis variables as well. To this end, there has been an emphasis on developing imaging standards and ways to make the image acquisition and analysis more consistent. However, biological conditions during FLIM-based AFI imaging are rarely considered as key sources of FLIM variability. Here, we present several experimental factors with supporting data of the cellular microenvironment such as confluency, pH, inter-/intracellular heterogeneity, and choice of cell line that need to be considered for accurate quantitative FLIM-based AFI measurement of cellular metabolism.

PMID- 30296356 TI - Large scale segmental bone defect healing through the combined delivery of VEGF and BMP-2 from biofunctionalized cortical allografts. AB - Large scale cortical allografts suffer from poor incorporation and healing and often end in graft failure 5-10 years after implantation. To reduce these failures we have developed a growth-factor loaded cortical allograft capable of delivering one or two factors with a degree of temporal control and precision that permits the early release of one growth factor followed by the later and more sustained release of the other. We have loaded vascular endothelial growth factor (VEGF) and bone morphogenetic protein-2 (BMP-2), both critical components of bone formation and repair, onto cortical long bone allografts such that the VEGF is released first and followed shortly by BMP-2. Coated and factor-loaded allografts were placed into a critical sized rat femoral segmental defect and allowed to heal for either 4 or 8 weeks. Healing at each time point was compared to allografts loaded with only BMP-2 and allografts containing no growth factors. Results indicate statistically significant increases in new bone formation from 4 to 8 weeks around allografts loaded with both VEGF and BMP-2 over allografts with no growth factor, suggesting that factor-loaded polymer-coated allografts delivering multiple factors with temporal precision may provide a new off-the shelf tool to the orthopedic surgeon for management of large-scale orthopedic bone defects.

AB - Acute myeloid leukemia (AML) is a genetically heterogeneous malignancy characterized by the expansion of hematopoietic stem/progenitor cells (HPCs) blocked at different stages of maturation/differentiation. The poor outcome of AMLs necessitates therapeutic improvement. In AML, genes encoding for myeloid transcription factors, signaling receptors regulating cell proliferation, and epigenetic modifiers can be mutated by somatically acquired genetic mutations or altered by chromosomal translocations. These mutations modify chromatin organization at genes sites regulating HPCs proliferation, terminal differentiation, and DNA repair, contributing to the development and progression of the disease. The reversibility of the epigenetic modifications by drug treatment makes epigenetic changes attractive targets for AML therapeutic intervention. Recent findings underline increased DNA damage and abnormalities in the DNA damage response (DDR) as a critical feature of AML blasts. The DDR preserves cell integrity and must be tightly coordinated with DNA methylation and chromatin remodeling to ensure the accessibility to the DNA of transcription factors and repair enzymes. A crucial role in these events is played by the ataxia telangiectasia mutated (ATM) and ataxia telangiectasia and Rad3-related protein (ATR) kinases, which are hyperactive in AML. Based on these findings, we hypothesize the inhibition of DNA damage kinases as an alternative or complementary strategy for the differentiation treatment of AML as it leads to a reduced ability to repair the DNA damage, and to the inhibition of specific epigenetic modifiers whose function is altered in leukemic cells.

AB - SCOPE: The bioactive constituents in ginger extract are responsible for anti hyperglycemic effects and the underlying mechanisms are incompletely understood. Gingerenone A (Gin A) has been identified as an inhibitor of p70 S6 (S6K1), a kinase that plays a critical role in the pathogenesis of insulin resistance. This study aims to evaluate if Gin A can sensitize the insulin receptor by inhibiting S6K1 activity. METHODS AND RESULTS: Western blot analysis reveals that Gin A induces phosphatidylinositide-3 kinase (PI3K) feedback activation in murine 3T3 L1 adipocytes and rat L6 myotubes, as evidenced by increased AKTS473 and S6K1T389 but decreases S6S235/236 and insulin receptor substrate 1 (IRS-1)S1101 phosphorylation. Western blot and immunoprecipitation analysis reveal that Gin A increases insulin receptor tyrosine phosphorylation in L6 myotubes and IRS-1 binding to the PI3K in 3T3-L1 adipocytes. Confocal microscopy reveals that Gin A enhances insulin-induced translocation of glucose transporter 4 (GLUT4) into the cell membrane in L6 cells. 2-NBDG (2-N-(Nitrobenz-2-oxa-1,3-diazol-4-yl)amino)-2 deoxyglucose) Fluorescent assay reveals that Gin A enhances insulin-stimulated glucose uptake in 3T3-L1 adipocytes and L6 myotubes. CONCLUSIONS: Gin A overcomes insulin resistance and increases glucose uptake by inhibiting S6K1 activity. Gin A or other plant-derived S6K1 inhibitors could be developed as novel antidiabetic agents. PMID- 30296359 TI - MCL1 Gene Silencing Promotes Senescence and Apoptosis of Glioma Cells via Inhibition of the PI3K/Akt Signaling Pathway. AB - Glioma is known to be the most prevalent primary brain tumor. In recent years, there has been evidence indicating myeloid cell leukemia-1 (MCL1) plays a role in brain glioblastoma. Therefore, the present study was conducted with aims of exploring the ability of MCL1 silencing to influence glioma cell senescence and apoptosis through the mediation of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway. Glioma and tumor-adjacent tissues were collected in order to detect the presence of higher levels of MCL1 protein expression. Next, the mRNA and protein expression of MCL1, PI3K, Akt, B cell lymphoma 2 (Bcl2), Bcl2-associated X (Bax), B lymphoma Mo-MLV insertion region 1 homolog (Bmi-1), and phosphatase and tensin homolog (PTEN) were determined. Cell counting kit-8 assay was applied to detect cell proliferation, beta-galactosidase staining for cell senescence, and flow cytometry for cell cycle entry and apoptosis. Initially, the results revealed higher positive expression rate of MCL1 protein, increased mRNA and protein expression of MCL1, PI3K, Akt, Bmi-1, and Bcl-2 and decreased that of Bax and PTEN in human glioma tissues. The silencing of MCL1 resulted in a decrease in mRNA and protein expression of PI3K, Akt, Bmi-1, and Bcl-2 and an increase in Bax and PTEN expressions in glioma cells. Moreover, silencing of MCL1 also inhibited cell proliferation and cell cycle entry in glioma cells, and promoted glioma cell senescence and apoptosis. In conclusion, the aforementioned results collectively suggested that the silencing of MCL1 promotes senescence and apoptosis in glioma cells through inhibiting the PI3K/Akt signaling pathway. Thus, decreasing the expression of MCL1 might have therapeutic functions in glioma. (c) 2018 IUBMB Life, 2018. PMID- 30296360 TI - In vitro remineralization of artificial enamel caries with resin composites containing calcium phosphate particles. AB - The aim of the study was to evaluate the effect of experimental composites containing dicalcium phosphate dihydrate (DCPD) on remineralization of enamel lesions. Five resin-based composites containing equal parts (in mols) of bisphenol-A glycidyl dimethacrylate (BisGMA), triethylene glycol dimethacrylate (TEGDMA), and 60 vol % of fillers were manipulated. Filler phase was constituted by silanized barium glass and 0, 10, or 20 vol % of DPCD particles, either functionalized (F) or nonfunctionalized (NF) with TEGDMA. Artificial subsurface lesions were produced in human enamel fragments and divided according to the resin composite applied on the lesion (no DCPD, 20% NF, 20% F, 10% NF, 10% F) plus a group without composite build-up (nontreated, NT). Fragments were exposed to 16 days of pH cycling. Specimens were evaluated using transverse microradiography (TMR). Calcium and phosphate concentrations in pH-cycling solutions were determined by spectrophotometry. TMR and ionic concentrations were analyzed using one-way ANOVA/Tukey and Kruskal-Wallis/Dunn test, respectively (alpha: 0.05). All composite groups showed enamel remineralization (3%-23%). Higher mineral recovery in the middle (7%-11%) and bottom (2%-7%) thirds of the lesion was observed in groups with DCPD-containing composites compared to the "no DCPD" group (middle: 1%, bottom: -3%). Lesion depth was significantly reduced in groups using DCPD-containing composites compared to NT group. No noticeable increase in calcium and phosphate ions was observed in the pH-cycling solutions due to the presence of DCPD in the composites. In conclusion, composites with DCPD fractions as low as 10%, regardless of functionalization, were able to promote mineral recovery and reduce lesion depth of enamel lesions.

AB - Few burn dressings can self-regulate the optimal humidity levels that are required for wound healing, while also providing good anti-adhesive properties to prevent damage that can occur when wound dressings are changed. Consequently, a water-soluble carboxymethylcellulose sodium/sodium alginate/chitosan (CMC Na/SA/CS) composite hydrogel has been developed as a potential burn wound dressing, with orthogonal testing revealing an optimal ratio of CMC-Na, SA, and CS as 2, 3, and 1 wt % for hydrogel preparation, respectively. The resultant hydrogel has been formulated into composite wound dressings that were then used for the treatment of deep second degree burn wounds in Sprague-Dawley (SD) rats. Analysis of the physical properties of this dressing revealed that it exhibits good water vapor permeability properties that promote the healing of deep second degree burn wounds. The pro-healing mechanism of the dressing has been investigated Vascular endothelial growth factor (VEGF) expression was upregulated and basic fibroblast growth factor (bFGF) expression was downregulated in the early periods of wound healing, with upregulation of bFGF then occurring at a later stage of wound healing. At the same time, the wound dressing decreased the levels of tumor necrosis factor-alpha and interleukin-6, thus validating its beneficial effect on the wound healing process at a biomolecular level. In conclusion, this new hydrogel dressing was shown to exhibit excellent self regulatory and anti-adhesive properties that synergistically promote the healing of burn wounds in rats, thus providing promising results that may have clinical applications.

AB - This paper presents three families of semi-interpenetrating polymer network (SIPN) hydrogels based on an ester-based polyurethane (EBPU) and hydrophilic monomers: N,N-dimethylacrylamide (NNDMA), N-vinyl pyrrolidone (NVP) and acryloylmorpholine (AMO) as potential materials for keratoprosthesis, orthokeratology and mini-scleral lens application. Hydrogels sheets were synthesized via free-radical polymerization with methods developed in-house. SIPN hydrogels were characterized for their equilibrium water content, mechanical and surface properties. Three families of optically clear SIPN-based hydrogels have been synthesized in the presence of water with >10% of composition attributable to EBPU. Water contents of SIPN materials ranged from 30% to 70%. SIPNs with <=15% EBPU of total composition showed little influence to mechanical properties, whereas >15% EBPU contributed significantly to an increase in material stiffness. In the hydrated state, SIPNs with <=15% EBPU of total composition show little difference in polar component (gammap ) of surface free energy, whereas for >15% EBPU there is a decrease in gammap . The EBPU SIPN hydrogels display complementary material properties for keratoprosthesis, orthokeratology, and mini scleral applications.

AB - OBJECTIVE: Hypothalamic obesity (HyOb) is a rare cause of rapid weight gain and early metabolic comorbidities. Effective treatment strategies are limited. The registry collected participant data and compared treatment approaches. METHODS: The International Registry of Hypothalamic Obesity Disorders (IRHOD) was created as a registry portal to provide education. Data collected from the initial 4 years were evaluated. RESULTS: Eighty-seven participants were included for analysis (median age: 27 years, range: 3-71 years). A total of 96.5% had obesity, and 3.5% had overweight at maximal weight. Seventy-five had brain tumors (86%) the majority were craniopharyngiomas (72% of those with tumors). Nontumor etiologies included congenital brain malformation (4.6%), traumatic brain injury (3.4%), and genetic anomaly (2.3%). Ninety percent received obesity treatments including nutritional counseling (82%), pharmacotherapy (59%), bariatric surgery (8%), and vagal nerve stimulation (1%). Forty-six percent reported follow-up BMI results after obesity treatment. Surgery was most effective (median BMI decrease: -8.2 kg/m2 , median interval: 2.6 years), with lifestyle intervention (BMI: -3.4 kg/m2 , interval: 1.2 years) and pharmacological therapy (BMI: -2.3 kg/m2 , interval: 0.8 years) being less effective. Eighty percent of participants reporting follow-up weight remained in the obesity range. CONCLUSIONS: IRHOD identified a large cohort with self-reported HyOb. Surgical therapy was most effective at weight reduction. Nutritional counseling and pharmacotherapy modestly improved BMI. Stepwise treatment strategy for HyOb (including nutritional, pharmacological, and surgical therapies in an experienced center) may be most valuable.

AB - This study aims to design an asymmetric dual coating (ADC) on the stent by ultrasonic atomization to solve the problem of delayed endothelialization and late or very late stent thrombosis which caused by drug eluting stent (DES) with symmetric coating. Chitosan-loaded monoclonal platelet glycoprotein IIIa receptor antibody SZ-21 coating (CSC) was sprayed on inner surface of stents, and outer surface was sprayed CSC and poly(lactic-co-glycolic acid) (PLGA) loaded with docetaxel (DTX) coating (PDC). The coated surface was uniform without aggregation and no shedding phenomenon either before or after stent expanded. Fluorescence labeling has confirmed that the coating has an asymmetric structure. The cumulative release for SZ-21 and DTX was 40.11% and 27.22% within first 24 h, then DTX became the major released drug from 24 h to 7 d, after released for 28 d about 40% of the SZ-21 and 50% DTX still remained on the coated stent. It achieved that ADC can inhibit thrombosis at earlier period and inhibit vascular smooth muscle cells (VSMCs) proliferation at later period. And that ADC has good hemocompatibility and can significantly inhibit VSMCs proliferation. Finally, 4 and 12 weeks after the stent with ADC implanted into rabbit carotid arteries, it showed that the stent with ADC was safe and could effectively prevent thrombosis and in-stent restenosis.

AB - As an energy-saving building material, transparent wood (TW) is highly attractive because of the advantages of high optical transmittance, excellent mechanical properties, and good thermal insulation. However, the current research is limited to fabricating small-size samples in the laboratory because thick or large-size transparent wood is almost impossible to be achieved. A method that can easily and efficiently produce transparent wood with any size and any thickness is desirable for practical applications. Transparent wood made from wood fibers as a substrate allows the cell walls to bind more tightly to the impregnated polymer, resulting in high light transmittance. Compared with wood prepared by using previously reported approaches, the transparent wood prepared by this new method not only retains the same advantages but also has higher preparation efficiency and is suitable for large-scale production. Under a simulated real environment, the retainability of indoor temperature by a sample house utilizing the transparent wood reveals excellent thermal insulation of the fiber-based transparent wood owing to its low thermal conductivity, showing significant benefits in saving thermal energy.

AB - OBJECTIVE: This study aimed to examine the intestinal microbiota composition of school-aged children in association with (over)weight. METHODS: The fecal microbiota composition of 295 children was analyzed using the Human Intestinal Tract Chip. Anthropometric outcomes (overweight [BMI >= 85th percentile], age- and sex-standardized BMI and weight z scores) were measured at 6 to 7 years of age, and elastic net was used to select genus-like bacterial groups related to all anthropometric outcomes. Subsequently, multiple linear and logistic regression models were used to model associations between selected bacterial groups and anthropometric measures while controlling for confounders. RESULTS: Prevotella melaninogenica, Prevotella oralis, Dialister, and uncultured Clostridiales II (UCII) accounted for 26.1% of the variation in microbiota composition. Several bacterial groups were inversely associated with the anthropometric outcomes: Sutterella wadsworthensis, Marvinbryantia formatexigens, Prevotella melanogenica, P oralis, Burkholderia, uncultured Clostridiales II, and Akkermansia, while Streptococcus bovis was positively associated with overweight. Microbial diversity and richness, and Bacteroidetes to Firmicutes ratio, were not significantly associated with any of the outcomes. CONCLUSIONS: In the largest population-based study on childhood gut microbiota and body weight so far, both new and previously identified bacterial groups were found to be associated with overweight. Further research should elucidate their role in energy metabolism. PMID- 30296367 TI - [ADHERENCE TO THE TREATMENT IN PATIENTS WITH TYPE 2 DIABETES MELLITUS AND WAYS TO ITS OPTIMIZATION]. AB - A total of 148 patients (50 men and 98 women) with type 2 diabetes who were hospitalized in the endocrinology department "Nizhny Novgorod Regional Hospital N.A. Semashko". It was shown based on the Morisky-Green scale that 91 patients (61.4%) did not comply with the doctor's recommendation. 57 (38.6%) patients adhered to the treatment. The patients showing poor compliance with the treatment were divided randomly into two groups. One was comprised of patients with type 2 diabetes (n = 45) who had been trained in the school of diabetic patients, provided with a special literature and kept a diary of self-monitoring blood glucose. The second group consisted of patients with type 2 diabetes (n = 46) also trained at the school of diabetes and provided with the relevant literature but were under active control (telephone calls, visits to the center). The year long prospective study demonstrated that adherence to treatment increased in the entire cohort. However, statistically significant positive dynamics of clinical and biochemical parameters was achieved only in the group of patients actively monitored by medical personnel. PMID- 30296368 TI - [VENOUS ECTASIA OF GASTRIC ANTRUM]. AB - Gastric antral vascular ectasia (GAVE) is an uncommon but often severe cause of upper gastrointestinal bleeding. GAVE may be asymptomatic or accompanied by clinical anemia or overt gastrointestinal bleeding. The diagnosis is mainly based on pathognomonic endoscopic pattern, defined as "watermelon stomach", located in antrum. Autoimmune disorders aye co-existing in about 60% of patients with GAVE, chirrosis in about 30%, and cardiac or renal failure in 10%.The "golden standarden" treatment of GAVE is endoscopic argon plasma coagulation (APC). There is poor information about diagnostics and treatment of GAVE in the domestic literature. The analysis of the presented materials shows that correct diagnostics takes much time and the choice of the optimum optimal treatment strategy encounters difficulty. Our experience with diagnostics and therapy of GAVE is based on the treatment of 4 patients. The diagnosis of GAVE was established within the period from 5 months to 1.5 years after onset of the disease. In two cases, GAVE was asymptomatic. Two patients with severe anemia completed endoscopic treatment; in one case, APC was supplemented by laser coagulation and bipolar coagulation. The implementation of laser coagulation caused some technical difficulties. Treatment of both patients was successful. Endoscopy pivotal for diagnosis of GAVE is the main method of its treatment. Due to the large number of diagnostic errors and the importance of correct diagnosis of GAVE, it is necessary to pay attention to this issue in training programs for endoscopists.

Materials and methods: This prospective cohort study included 337 patients with compromised carbohydrate metabolism (36 with impaired fasting glycemia or impaired glucose tolerance, 80 with type 1 diabetes, 194 with type 2 diabetes, 27 with diabetes due to chronic pancreatitis). Mean follow-up was 11.2+/-4.8 years (from 1 January 1995 through 31 December 2014). We investigated causes and risk factors of death in patients with impaired carbohydrate metabolism. Results: 115 patients died during the study period. The most common causes of death of patients with type 1 and 2 diabetes are cardiovascular diseases and cancer. Risk factors of death in type 1 DM include cardiovascular disease, diabetic nephropathy and retinopathy. Patients die at a younger age due to early onset of the disease. In type 2 diabetes risk factors of death are cardiovascular and oncologic diseases, nephropathy, the use of insulin. Patients die in elderly and senile age due to the late onset of diabetes. Gender differences in mortality associated with type 1 and 2 diabetes mellitus were not observed. Conclusion: Main causes of death in patients with type 1 and 2 DM are cardiovascular diseases and cancer. Risk factors of death include macro - and microvascular complications.

AB - The novel candy-like Cu4O3 microstructure has been synthesized successfully for the first time by a facile wet chemical method, and the formation mechanism was studied based on series of control experiments. The antibacterial activities of the candy-like Cu4O3 were evaluated by means of Gram-negative Escherichia coli ( E. coli) and Gram-positive Staphylococcus saureus ( S. aureus). The antibacterial mechanism was investigated by tracing the morphology evolution of the bacteria. The results show that the candy-like Cu4O3 microstructure was formed underwent the route of Cu(NH3)42+ -> Cu(OH)42- -> Cu(OH)2 -> CuO -> Cu4O3 nuclei -> Cu4O3 crystal growth -> candy-like Cu4O3, and optimal reaction conditions are required to obtain the candy-like Cu4O3. The candy-like Cu4O3 microstructure exhibits good long-term antibacterial activities to both E. coli and S. aureus bacteria. Critical concentration of Cu2+ ions released from the candy-like Cu4O3 was found responsible for the sudden increase beyond 90% in antibacterial activity. PMID- 30296371 TI - Syntheses of Molybdenum Oxo Benzylidene Complexes. AB - The reaction between Mo(O)(CHAro)(ORF6)2(PMe3) (Aro = ortho-methoxyphenyl, ORF6 = OCMe(CF3)2) and 2 equiv of LiOHMT (OHMT = O-2,6-(2,4,6-Me3C6H2)2C6H3) leads to Mo(O)(CHAro)(OHMT)2, an X-ray structure of which shows it to be a trigonal bipyramidal anti benzylidene complex in which the o-methoxy oxygen is coordinated to the metal trans to the apical oxo ligand. Addition of 1 equiv of water (in THF) to the benzylidyne complex, Mo(CArp)(OR)3(THF)2 (Arp = para-methoxyphenyl, OR = ORF6 or OC(CF3)3 (ORF9)) leads to formation of {Mo(CArp)(OR)2(MU OH)(THF)}2(MU-THF) complexes. Addition of 1 equiv of a phosphine (L) to Mo(CArp)(ORF9)3(THF)2 in THF, followed by addition of 1 equiv of water, all at room temperature, yields Mo(O)(CHArp)(ORF9)2(L) complexes in good yields for several phosphines (e.g., PMe2Ph (69% by NMR), PMePh2 (59%), PEt3 (69%), or P( i Pr)3 (65%)). The reaction between Mo(O)(CHArp)(ORF9)2(PEt3) and 2 equiv of LiOHMT proceeds smoothly at 90 degrees C in toluene to give Mo(O)(CHArp)(OHMT)2, a four coordinate syn alkylidene complex. Mo(O)(CHArp)(OHMT)2 reacts with ethylene (1 atm in C6D6) to give (in solution) a mixture of Mo(O)(CHArp)(OHMT)2, Mo(O)(CH2)(OHMT)2, and an unsubstituted square pyramidal metallacyclobutane complex, Mo(O)(CH2CH2CH2)(OHMT)2, along with ethylene and ArpCH?CH2. Mo(O)(CHArp)(OHMT)2 also reacts with 2,3-dicarbomethoxynorbornadiene to yield syn and anti isomers of the "first-insertion" products that contain a cis C?C bond.

AB - The Article presents the synthesis, structure, and bonding of a series of neutral and linear sandwich compounds with the cyclononatetraenyl (Cnt) ligand and divalent lanthanides. These compounds account for the emergence of the lanthanidocene series in reference to the ferrocene and uranocene. The synthetic strategy uses the solubility difference between two conformational isomers of the ligand, as well as the isomerization of the compounds induced by solvent coordination, yielding the isomorphous and isostructural neutral and rigorously linear sandwich complexes. The molecular structures feature a Cnt-Ln-Cnt angle of 180 degrees and a ring size close to the Cnt-Cnt(centroid) distance. A qualitative molecular orbital diagram is provided, in D9 d symmetry, and DFT calculations enforce the bonding model. PMID- 30296373 TI - Tunable Stability of Imidazotetrazines Leads to a Potent Compound for Glioblastoma. AB - Even in the era of personalized medicine and immunotherapy, temozolomide (TMZ), a small molecule DNA alkylating agent, remains the standard-of-care for glioblastoma (GBM). TMZ has an unusual mode-of-action, spontaneously converting to its active component via hydrolysis in vivo. While TMZ has been FDA approved for two decades, it provides little benefit to patients whose tumors express the resistance enzyme MGMT and gives rise to systemic toxicity through myelosuppression. TMZ was first synthesized in 1984, but certain key derivatives have been inaccessible due to the chemical sensitivity of TMZ, precluding broad exploration of the link between imidazotetrazine structure and biological activity. Here, we sought to discern the relationship between the hydrolytic stability and anticancer activity of imidazotetrazines, with the objectives of identifying optimal timing for prodrug activation and developing suitable compounds with enhanced efficacy via increased blood-brain barrier penetrance. This work necessitated the development of new synthetic methods to provide access to previously unexplored functionality (such as aliphatic, ketone, halogen, and aryl groups) at the C8 position of imidazotetrazines. Through synthesis and evaluation of a suite of compounds with a range of aqueous stabilities (from 0.5 to 40 h), we derive a predictive model for imidazotetrazine hydrolytic stability based on the Hammett constant of the C8 substituent. Promising compounds were identified that possess activity against a panel of GBM cell lines, appropriate hydrolytic and metabolic stability, and brain-to-serum ratios dramatically elevated relative to TMZ, leading to lower hematological toxicity profiles and superior activity to TMZ in a mouse model of GBM. This work points a clear path forward for the development of novel and effective anticancer imidazotetrazines. PMID- 30296374 TI - Structural and Computational Assessment of the Influence of Wet-Chemical Post Processing of the Al-Substituted Cubic Li7La3Zr2O12. AB - Li7La3Zr2O12 (LLZO) and related compounds are considered as promising candidates for future all-solid-state Li-ion battery applications. Still, the processing of those materials into thin membranes with the right stoichiometry and crystal structure is difficult and laborious. The sensitivity of the Li-ion conductive garnets against moisture and the associated Li+/H+ cation exchange makes their processing even more difficult. Formulation of suitable polymer/ceramic hybrid solid state electrolytes could be a prosperous way to reach the future large scale production of solid state Li-ion batteries. In fact, solvent mediated and/or slurry based wet-processing of the LLZO, e.g., tape-casting, could result in irreversible Li-ion loss of the pristine material due to Li+/H+ cation exchange. The concomitant structural changes and loss in functionality in terms of Li-ion conductivity are the results of the above process. Therefore, in the present work a systematic study on the chemical stability and structural retention of Al-substituted LLZO in different solvents is reported. It was found that Li+/H+ exchange in LLZO occurs upon solvent immersion, and its magnitude is dependent on the availability of -OH functional groups of the solvent molecules. As a result, a larger degree of Li+/H+ exchange causes higher increase of the lattice parameter of the LLZO, determined by synchrotron diffraction analyses. The expansion of the cubic unit cell was ascertained, when Li+ was replaced by H+ in the host lattice, by ab initio computational studies. The application of the most common solvent as dispersion medium, i.e., high purity water, causes the most significant Li+/H+ exchange and, therefore, structural change, while acetonitrile was proven to be the best suitable solvent for wet postprocessing of LLZO. Finally, computational calculations suggested that the Li+/H+ exchange could result in diminished ionic, i.e., mixed Li+-H+, conductivity due to the insertion of protons with lower mobility than that of Li-ions. PMID- 30296375 TI - Erlotinib-Guided Self-Assembled Trifunctional Click Nanotheranostics for Distinguishing Druggable Mutations and Synergistic Therapy of Nonsmall Cell Lung Cancer. AB - The outcome of molecular targeted therapies is restricted by the ambiguous molecular subtypes of nonsmall cell lung cancer (NSCLC), which are difficult to be defined with druggable mutations, and the inevitable emergence of drug resistance. Here we used the Cu-catalyzed click chemistry to synthesize a chitosan-based self-assembled nanotheranostics (CE7Ns) composed of a near infrared (NIR) fluorescent photosensitizer Cy7 and molecular targeted drug erlotinib. The well-characterized CE7Ns can release erlotinib and Cy7 fast under acidic condition in the presence of lysozyme, distinguish three molecular subtypes of NSCLC, and specifically bind to the erlotinib-sensitive epidermal growth factor receptor (EGFR)-mutated PC-9 cells. The uptake of CE7Ns is much more in PC-9 cells than in other NSCLC cells, thus generating a notable fluorescence signal in PC-9 cells. Upon NIR irradiation, Cy7 in CE7Ns produces high reactive oxygen species in PC-9 cells. The synergistic effect between erlotinib-targeted therapy and photodynamic therapy significantly up-regulates cancer suppressor p53 and inhibits Survivin, which results in more apoptosis and cell cycle arrest. Upon intravenous administration, the erlotinib-guided CE7Ns significantly accumulate in PC-9-seeded mouse lungs and produce strong fluorescence. Upon NIR irradiation, CE7Ns significantly inhibit the subcutaneously implanted PC-9 tumor growth. This study provides, for the first time, a novel strategy to synthesize a multifunctional theranostic entity to simultaneously distinguish and image druggable mutations and combine targeted therapy with photodynamic therapy to overcome drug resistance. PMID- 30296376 TI - Evaluation of Novel Tumor-Targeted Near-Infrared Probe for Fluorescence-Guided Surgery of Cancer. AB - Because the most reliable therapy for cancer involves quantitative resection of all diseased tissue, considerable effort has been devoted to improving a surgeon's ability to locate and remove all malignant lesions. With the aid of improved optical imaging equipment, we and others have focused on developing tumor-targeted fluorescent dyes to selectively illuminate cancer nodules during surgery. We describe here the design, synthesis, optical properties, in vitro and in vivo tumor specificity/affinity, pharmacokinetics, preclinical toxicology, and some clinical application of a folate receptor (FR)-targeted NIR dye (OTL38) that concentrates specifically in cancer tissues and clears rapidly from healthy tissues. We demonstrate that OTL38 binds FR-expressing cells with ~1 nM affinity and eliminates from receptor negative tissues with a half-time of <30 min. We further show that OTL38 enables visualization of malignant lesions at concentrations less than 100-fold those required to elicit signs of toxicity. Since OTL38 also provides excellent tumor contrast in both murine tumor models and human cancer patients, we conclude that OTL38 constitutes an excellent NIR dye for fluorescence-guided resection of malignant lesions in cancer patients.

AB - Light-driven recombinant protein (RP) production in eukaryotic microalgae offers a sustainable alternative to other established cell-culture systems. RP production via secretion into the culture medium enables simple product separation from the cells adding a layer of process value in addition to the algal biomass, which can be separately harvested. For the model microalga Chlamydomonas reinhardtii, a broad range of molecular tools have been established to enable heterologous gene expression; however, low RP production levels and unreliable purification from secretion concepts have been reported. Domesticated C. reinhardtii strains used for genetic engineering are often cell-wall deficient. These strains nevertheless secrete cell-wall components such as insoluble (hydroxy)proline-rich glycoproteins into the culture media, which hinder downstream purification processes. Here, we attempted to overcome limitations in secretion titers and improve protein purification by combining fusion partners that enhance RP secretion and enable alternative aqueous two phase (ATPS) RP extraction from the culture medium. Protein fusions were strategically designed to contain a stably folded peptide, which enhanced secretion capacities and gave insights into (some) regulatory mechanisms responsible for this process in the algal host. The elevated protein titers mediated by this fusion were then successfully applied in combination with a fungal hydrophobin tag, which enabled protein purification from the complex microalgal extracellular environment by ATPS, to yield functional recombinant human epidermal growth factor (hEGF) from the algal host.

AB - Achieving a novel structural construction and adopting appropriate catalyst materials are key to overcoming inherent limitations of gas sensors in terms of designing sensing layers. This work introduces NiO/NiCo2O4 truncated nanocages functionalized with PdO nanoparticles, which were proved to possess the ability of effective acetone detection. The device realized an enhanced acetone-sensing sensitivity, together with excellent selectivity and long-term stability. The sensing performance is far better than sensors based on NiO/NiCo2O4 solid nanocubes and NiO/NiCo2O4 truncated nanocages without PdO decorating, which is related to cooperative effects of the high specific surface area and efficient catalytic activity. The results provide promising metal-organic frameworks (MOFs) derived material with the optimization of catalytic performance, demonstrating the remarkable potential for acetone sensors. PMID- 30296378 TI - Dual-Ion-Mode MALDI MS Detection of Small Molecules with the O-P,N-Doped Carbon/Graphene Matrix. AB - It is challenging to realize a dual-ion mode of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) for detecting small molecules. Herein, graphene coated by porous amorphous carbon with P-O surface group and codoped by phosphorus and nitrogen (O-P,N-C/G) was synthesized from an aerogel formed by phytic acid, polyaniline, and electrochemically exfoliated graphene. The carbon material synthesized has the feature of large surface area (583 m2/g), good electrical conductivity, strong UV absorption, heteroatom doping, and surface functional groups suitable for laser- induced desorption/ionization. It was employed as a novel matrix suitable for both positive-ion and negative-ion modes in MALDI-TOF MS for the analysis of various small molecules including amino acids, small peptides, saccharides, drugs, and environmental pollutants, significantly outperforming control materials and a traditional CHCA (alpha-cyano-4-hydroxycinnamic acid) or 2,5 dihydroxybenzoic (DHB) matrix. Remarkably, the detection limit of the anticancer drugs (5-fluorouracil and ellagic acid) reaches 50 pmol. In addition, nice MALDI TOF MS images can be mapped to detect mixed amino acids corresponding to homogeneous distribution of ion intensity. The monosaccharides and disaccharides can be distinguished by using the new matrix. Last but not least, it can be used to quantitatively detect glucose in human serum and soft drinks (glucose/fructose, 203.1 mM) without adding standards. PMID- 30296380 TI - Morphological Engineering of Winged Au@MoS2 Heterostructures for Electrocatalytic Hydrogen Evolution. AB - Molybdenum disulfide (MoS2) has been recognized as a promising cost-effective catalyst for water-splitting hydrogen production. However, the desired performance of MoS2 is often limited by insufficient edge-terminated active sites, poor electrical conductivity, and inefficient contact to the supporting substrate. To address these limitations, we developed a unique nanoarchitecture (namely, winged Au@MoS2 heterostructures enabled by our discovery of the "seeding effect" of Au nanoparticles for the chemical vapor deposition synthesis of vertically aligned few-layer MoS2 wings). The winged Au@MoS2 heterostructures provide an abundance of edge-terminated active sites and are found to exhibit dramatically improved electrocatalytic activity for the hydrogen evolution reaction. Theoretical simulations conducted for this unique heterostructure reveal that the hydrogen evolution is dominated by the proton adsorption step, which can be significantly promoted by introducing sufficient edge active sites. Our study introduces a new morphological engineering strategy to make the pristine MoS2 layered structures highly competitive earth-abundant catalysts for efficient hydrogen production. PMID- 30296381 TI - In Vivo and Cellular Trafficking of Acetalated Dextran Microparticles for Delivery of a Host-Directed Therapy for Salmonella enterica Serovar Typhi Infection. AB - Previously we have encapsulated host-directed therapy AR-12 into acetalated dextran (Ace-DEX) microparticles (MPs) to mitigate drug toxicity and passively target phagocytic host cells. Herein, we have improved upon our initial emulsion based formulation of Ace-DEX MPs encapsulating AR-12 (AR-12/MPs) by improving the drug encapsulation efficiency, evaluating sterilization processes for manufacturing, and understanding cellular and in vivo trafficking of the MPs. By using an alternative solvent system, ethyl acetate, we report an increased encapsulation efficiency of AR-12 while maintaining the pH-responsive degradation kinetics of Ace-DEX MPs. To better manufacture this novel antimicrobial formulation, we sterilized AR-12/MPs by gamma irradiation or ethylene oxide and evaluated their efficacy against intracellular Salmonella enterica serovar Typhi. Sterilized AR-12/MPs resulted in a significant reduction in intracellular bacterial burden compared to Blank/MPs. We also characterized intracellular trafficking of Ace-DEX MPs encapsulating fluorophores, which demonstrated internalization of MPs in endo/lysosomal compartments and time and degradation rate dependent lysosomal escape into cytosolic compartments. Additionally, in vivo toxicity was mitigated following encapsulation of AR-12, where the maximum tolerated dose of AR-12 was increased compared to soluble treatment via intranasal, intravenous, and intraperitoneal administration routes. Following in vivo trafficking of Ace-DEX MPs via the same routes, intranasal administration demonstrated the highest accumulation in the lungs, liver, and kidneys, which persisted out to 240 h. Overall, we have advanced the formulation of this host directed therapy and broadened the understanding of Ace-DEX MP delivery. PMID- 30296382 TI - Candida rugosa lipase encapsulated with magnetic sporopollenin: design and enantioselective hydrolysis of racemic arylpropanoic acid esters. AB - The aim of this study was to prepare the encapsulation of Candida rugosa lipase (CRL) with magnetic sporopollenin. The sporopollenin was covalent immobilized onto magnetic nanoparticles (Fe3O4), grafted amino (APTES), or epoxy groups (EPPTMS). CRL was sol-gel encapsulated in the presence of magnetic sporopollenin/Fe3O4 nanoparticles. The influence of activation agents ([3-(2,3 epoxypropoxy) propyl] trimethoxysilane (EPPTMS), (3-Aminopropyl)triethoxysilane (APTES) and pH and thermal stabilities of the biocatalyst were assessed. Experimental data showed the improved catalytic activity at different pH and temperature values. At 60 degrees C, free lipase lost its initial activity within 80 min of time, although the encapsulated lipases retained their initial activities of about 65% by APTES and 60% by EPPTMS after 120 min of heat treatment at 60 degrees C. The catalytic properties of the encapsulated lipases were utilized to hydrolysis of racemic aromatic carboxylic acid methyl esters (Naproxen and 2-phenoxypropionic acid). The results show that the sporopollenin based encapsulated lipase (Fe-A-Spo-E) has greater enantioselectivity and conversion in comparison with the encapsulated lipase without supports (lipase enc). PMID- 30296383 TI - Subjective discomfort caused by vertical whole-body vibration in the frequency range 2-100 Hz. AB - Current standards assume the same frequency weightings for discomfort at all magnitudes of vibration, whereas biodynamic and psychological studies show that the frequency-dependence of objective and subjective responses of the human body depends on the magnitude of vibration. This study investigated the discomfort of seated human body caused by vertical whole-body vibration over the frequency range 2-100 Hz at relatively high magnitudes from 1.0 to 2.5 ms-2 r.m.s. Twenty eight subjects (15 males and 13 females) judged the discomfort using the absolute magnitude estimation method. The rate of growth of discomfort with increasing vibration magnitude was highly depended on the frequency, so the shapes of the equivalent comfort contours depended on the magnitude of vibration and no single frequency weighting would be appropriate for all magnitudes. The equivalent comfort contours indicated that the standards and previous relevant studies underestimated the vibration discomfort at frequencies greater than about 30 Hz. Practitioner summary: The discomfort caused by vertical vibration at relatively high frequencies can be severe, particularly at relatively great magnitudes in transport. This study provides the frequency-dependence of vibration discomfort at 2-100 Hz, and shows how the frequency weightings in the current standards can be improved at relatively high frequencies. PMID- 30296384 TI - Cognitive impairment in chronic obstructive pulmonary disease: disease burden, determinants and possible future interventions. AB - INTRODUCTION: Cognitive impairment (CI) is an important but an under-recognized extra-pulmonary feature of chronic obstructive pulmonary disease (COPD). It is related to the burden of disability, worse health outcomes, and impaired self management. Areas covered: CI includes deterioration of a wide range of cognitive functions, such as memory and various executive functions. Risk of hospitalization might be higher in patients with COPD compared to those without, with CI negatively impacting the wellbeing of patients with COPD. Disease specific factors such as hypoxemia and inflammation, lifestyle factors such as dietary insufficiencies and lack of physical activity, and comorbidities such as obstructive sleep apnea and depression are likely to synergistically contribute to the development of CI in COPD. Tailored interventions can possibly improve CI in COPD, but this needs further investigation. Expert commentary: Further research is warranted involving the optimization of neuropsychological testing for screening and outcome assessment, longitudinal studies to investigate the development of CI in COPD over time, and randomized clinical trials to test the feasibility and efficacy of promising interventions. PMID- 30296385 TI - Improved accumulation of betulin and betulinic acid in cell suspension culture of Betula pendula roth by abiotic and biotic elicitors. AB - Betulin (B) and betulinic acid (BA) are two triterpenes with diverse pharmacological and physiological actions. Elicitation of Betula pendula Roth cell cultures by elicitors is an excellent strategy to increase B and BA levels. Six abiotic and biotic elicitors were studied to improve accumulation of B and BA in the cell culture of B. pendula. The B and BA production in treated cells was verified by HPLC. The results showed the maximum growth index (7) on day 3 in cells treated with 0.5 mg L-1 chlorocholine chloride (CCC). The increased accumulation of BA in the cells treated with 200 mg L-1 of chitosan was found to be 5.9 * (6.5 mg g-1 DW) higher over control cells. Treating the cells with 2 mg L-1 of CCC, after 7 days, led to 149.3* enhancement of B content (19.4 mg g-1 DW) over the controls. Production of this triterpenoid at a much shorter time with a much higher growth rate can be economic and lead to producing large amounts of B and BA for anti-cancer and HIV drugs preparation.

The Acute Medically Ill VTE Prevention with Extended Duration Betrixaban (APEX) trial evaluated the efficacy and safety of extended duration betrixaban compared to standard duration enoxaparin in acutely ill hospitalized patients. Areas covered: This article describes the role of betrixaban in the prevention of venous thromboembolism (VTE) in acutely ill medical patients. This article provides a consolidated summary of the primary APEX study findings as well as prespecified and exploratory substudies. This article also provides a review of the results of studies in which other direct factor Xa inhibitors have been evaluated in an extended duration regimen in this patient population. Expert commentary: While previous agents have demonstrated that extended duration VTE prophylaxis can be efficacious, betrixaban is the first agent to demonstrate efficacy without an increase in major bleeding. The totality of the data from the APEX trial supports extended duration betrixaban for VTE prophylaxis in the acute medically ill patient population. As such, betrixaban has been approved in the USA for extended VTE prophylaxis in at-risk acute medically ill patients.

PMID- 30296390 TI - Mucins and Their Role in Shaping the Functions of Mucus Barriers. AB - We review what is currently understood about how the structure of the primary solid component of mucus, the glycoprotein mucin, gives rise to the mechanical and biochemical properties of mucus that are required for it to perform its diverse physiological roles. Macroscale processes such as lubrication require mucus of a certain stiffness and spinnability, which are set by structural features of the mucin network, including the identity and density of cross-links and the degree of glycosylation. At the microscale, these same features affect the mechanical environment experienced by small particles and play a crucial role in establishing an interaction-based filter. Finally, mucin glycans are critical for regulating microbial interactions, serving as receptor binding sites for adhesion, as nutrient sources, and as environmental signals. We conclude by discussing how these structural principles can be used in the design of synthetic mucin-mimetic materials and provide suggestions for directions of future work in this field. PMID- 30296391 TI - Caveolae: Structure, Function, and Relationship to Disease. AB - The plasma membrane of eukaryotic cells is not a simple sheet of lipids and proteins but is differentiated into subdomains with crucial functions. Caveolae, small pits in the plasma membrane, are the most abundant surface subdomains of many mammalian cells. The cellular functions of caveolae have long remained obscure, but a new molecular understanding of caveola formation has led to insights into their workings. Caveolae are formed by the coordinated action of a number of lipid-interacting proteins to produce a microdomain with a specific structure and lipid composition. Caveolae can bud from the plasma membrane to form an endocytic vesicle or can flatten into the membrane to help cells withstand mechanical stress. The role of caveolae as mechanoprotective and signal transduction elements is reviewed in the context of disease conditions associated with caveola dysfunction. PMID- 30296392 TI - Writing, Reading, and Translating the Clustered Protocadherin Cell Surface Recognition Code for Neural Circuit Assembly. AB - The ability of neurites of individual neurons to distinguish between themselves and neurites from other neurons and to avoid self (self-avoidance) plays a key role in neural circuit assembly in both invertebrates and vertebrates. Similarly, when individual neurons of the same type project into receptive fields of the brain, they must avoid each other to maximize target coverage (tiling). Counterintuitively, these processes are driven by highly specific homophilic interactions between cell surface proteins that lead to neurite repulsion rather than adhesion. Among these proteins in vertebrates are the clustered protocadherins (Pcdhs), and key to their function is the generation of enormous cell surface structural diversity. Here we review recent advances in understanding how a Pcdh cell surface code is generated by stochastic promoter choice; how this code is amplified and read by homophilic interactions between Pcdh complexes at the surface of neurons; and, finally, how the Pcdh code is translated to cellular function, which mediates self-avoidance and tiling and thus plays a central role in the development of complex neural circuits. Not surprisingly, Pcdh mutations that diminish homophilic interactions lead to wiring defects and abnormal behavior in mice, and sequence variants in the Pcdh gene cluster are associated with autism spectrum disorders in family-based genetic studies in humans. PMID- 30296393 TI - Introduction: Challenges for Science: A Retrospective. PMID- 30296394 TI - Biomarkers of exposure and effect in a working population exposed to lead, manganese and arsenic. AB - Lead (Pb), manganese (Mn) and arsenic (As) are among the major toxicants in mining environments. Miners are commonly and repeatedly exposed to this toxic mixture. Some adverse effects may appear at concentrations below environmental quality guidelines for individual mixture components. Further, Pb, Mn, and As induce common adverse outcomes, such as interferences in the cholinergic system and heme synthesis. It is thus vital to monitor miners through biomarkers (BM), such that subclinical effects may be identified at an early stage. The main objectives of this study were to evaluate the exposure of a mining population to these three metals and determine alterations in cholinergic and heme synthesis parameters. Blood and urine samples of workers (n = 60) were obtained from a Portuguese mining industry and compared with a control population (n = 80). The levels of the metals were determined in biological samples, as well as urinary heme precursor levels, delta aminolevulinic acid (ALA) and porphyrins, and blood acetylcholinesterase (AChE) activity. The miners exhibited significantly higher values of Pb and As in blood and urine compared to control. In the case of Mn near or slightly higher than limit values were found. Our data show that heme precursors may be used simultaneously with metal levels as BMs for multiple metal exposures on an individual basis, resulting in 94.3% and 95.7% accuracy, respectively, in blood and urine, for subjects correctly identified with respect to occupation. This study also revealed that biological monitoring of this working population regarding metal body burden and heme precursor accumulation is advisable. PMID- 30296395 TI - Hepatitis B contact tracing: what works? AB - In 2012, over 239000 people were living in Australia with chronic hepatitis B (CHB). Australia's Second National Hepatitis B Strategy (2014) recommends testing contacts to increase identification of people with CHB, but it is generally poorly performed. CHB prevalence in Australia is increasing and contact tracing (CT) remains an untapped strategy for identifying infected individuals. A systematic CT system has been established in a government-funded primary health centre in Melbourne, which services 2000 refugees. This mixed-methods study aimed to describe the structure of the CT system, determine its effectiveness and identify enablers of success. The CT system's structure was elicited from field notes. CT effectiveness (proportion of contacts traced and serologically confirmed as infected or immune to HBV) was determined by auditing clinical records. Semi-structured interviews with seven health professionals were thematically analysed to identify enablers of CT success. Overall, 122 CHB index cases had 420 contacts. And 90.0% (n=380) of 420 contacts were successfully traced, 68.0% (n=83) of index cases had 100% of their contacts successfully traced and 80.7% (n=339) of all contacts were immune; 28.8% (n=121) had evidence of previous exposure and 55.0% (n=231) had evidence of vaccination. Also, 8.1% (n=34) were chronically infected. Interviews elicited seven themes important to the success of the CT system: Teamwork; Organisation; Health professional expertise; Patient education; Centralisation of the system; Influence of patient culture; and Use of nurses in CT. Teamwork and Organisation were previously unidentified in the literature. This CT system is successful and could be implemented elsewhere, provided an organised, cohesive, nurse-led team is established. PMID- 30296397 TI - Universal Screening for Social Needs in a Primary Care Clinic: A Quality Improvement Approach Using the Your Current Life Situation Survey. AB - CONTEXT: Kaiser Permanente's Care Management Institute created a screening tool, Your Current Life Situation (YCLS), which primarily is used to identify social needs for populations at risk of high health care utilization. OBJECTIVE: This frontline improvement project was designed to address key stakeholder concerns about implementing universal screening for social needs using the YCLS in a primary care clinic. METHODS: I conducted a rapid stakeholder analysis through informal conversations to identify the most important concerns. Four Plan-Do Study-Act cycles were conducted to answer stakeholder questions and address concerns. RESULTS: Stakeholders expressed concerns including YCLS length and low screening acceptability and the possibility that too few or too many patients may have social needs. Throughout the project's duration, 125 office visits occurred and 111 patients were screened. Among the patients for whom findings were positive, 27% requested help. Of the 14 patients who were not screened, only 1 patient opted out of screening. Practitioners and medical assistants stated that administration of the YCLS screening tool did not disrupt clinic workflow. CONCLUSION: By using a frontline improvement approach, these investigators could answer questions and address concerns most important to local operational stakeholders when implementing screening for social needs. When practitioners conduct universal social needs screening and more fully understand social needs prevalence in a primary care clinic, resources can be tailored more effectively to accommodate patient needs. PMID- 30296396 TI - Relationship Between Adverse Childhood Experience Survey Items and Psychiatric Disorders. AB - CONTEXT: Developmental psychopathology theory suggests a relationship between early childhood adversity and mental disorder. OBJECTIVE: To examine the relationship between the specific items on the Adverse Childhood Experiences (ACE) survey and the International Classification of Diseases, Tenth Revision (ICD-10) categories of psychiatric diagnoses in a pediatric sample. DESIGN: The sample included patients enrolled in the Child and Adolescent Addiction Mental Health and Psychiatry Program with both a completed ACE survey and at least 1 diagnosis of record (per admission). These criteria yielded 2 samples for each sex (ACE survey item frequencies and values in collapsed and multiple-admission groups). Data were analyzed employing tetrachoric correlation, hierarchical regression, and polychoric factor analysis. RESULTS: Hierarchical regression analysis identified that ICD-10 diagnostic categories, except for substance disorders, were not consistently related to ACE total score and tended to reduce the magnitude of the ACE total score in the multiple-admission group. Tetrachoric correlation revealed very low (< 0.4) positive and negative correlations between ICD-10 categories and ACE items in both multiple-admission and collapsed sample groups. Polychoric factor analysis indicated that the ACE survey items and the ICD-10 categories for both sexes were independent, with only the diagnostic ICD 10 category substance disorders being marginally associated with the ACE items factor for females. CONCLUSION: The nominal relationship between ACE items and ICD-10 diagnostic categories indicates the need to include ACE assessment in advance of differential diagnosis and implementation of conventional mental health interventions for children and adolescents. PMID- 30296398 TI - Using Neighborhood-Level Census Data to Predict Diabetes Progression in Patients with Laboratory-Defined Prediabetes. AB - CONTEXT: Research on predictors of clinical outcomes usually focuses on the impact of individual patient factors, despite known relationships between neighborhood environment and health. OBJECTIVE: To determine whether US census information on where a patient resides is associated with diabetes development among patients with prediabetes. DESIGN: Retrospective cohort study of all 157,752 patients aged 18 years or older from Kaiser Permanente Northern California with laboratory-defined prediabetes (fasting plasma glucose, 100 mg/dL 125 mg/dL, and/or glycated hemoglobin, 5.7%-6.4%). We assessed whether census data on education, income, and percentage of households receiving benefits through the US Department of Agriculture's Supplemental Nutrition Assistance Program (SNAP) was associated with diabetes development using logistic regression controlling for age, sex, race/ethnicity, blood glucose levels, and body mass index. MAIN OUTCOME MEASURE: Progression to diabetes within 36 months. RESULTS: Patients were more likely to progress to diabetes if they lived in an area where less than 16% of adults had obtained a bachelor's degree or higher (odds ratio [OR] =1.22, 95% confidence interval [CI] = 1.09-1.36), where median annual income was below $79,999 (OR = 1.16 95% CI = 1.03-1.31), or where SNAP benefits were received by 10% or more of households (OR = 1.24, 95% CI = 1.1-1.4). CONCLUSION: Area-level socioeconomic and food assistance data predict the development of diabetes, even after adjusting for traditional individual demographic and clinical factors. Clinical interventions should take these factors into account, and health care systems should consider addressing social needs and community resources as a path to improving health outcomes. PMID- 30296399 TI - Inadequate Clinical Indications in Computed Tomography Chest and Abdomen/Pelvis Scans. AB - CONTEXT: As the use of computed tomography (CT) scans, which are expensive and result in considerable radiation exposure to the patient, continues to increase, communication between physicians and radiologists remains vital to explain the clinical context for the examination. However, the clinical information provided to the radiologist is often lacking. OBJECTIVE: To determine whether the clinical information provided in CT scan requests meets minimum criteria for requesting the examination. METHODS: We reviewed the clinical indications for 400 CT chest scans and 400 CT abdomen/pelvis scans performed from January 1, 2016, through March 8, 2016. We determined whether each CT study indication was complete on the basis of whether the clinical information included an adequate clinical history with 1) a primary symptom, 2) the location of the symptom, and 3) the duration of the symptom as well as a suspected etiology. RESULTS: Of the CT chest indications, 56 (14.0%) of the clinical histories were considered complete and 17 (4.3%) had none of the components. A principal etiology was included in 195 (48.8%) of the indications. Of the CT abdomen/pelvis indications, 94 (23.5%) of the clinical histories were complete and 13 (3.3%) had none of the components. A principal etiology was included in 173 (43.3%) of the indications. Only 23 (5.8%) of the CT chest studies and 35 (8.8%) of the CT abdomen/pelvis studies had information considered sufficient for the radiologist. CONCLUSION: The percentage of complete clinical indications for both CT chest and abdomen/pelvis scans was much lower than 50%, suggesting that more emphasis should be placed on providing complete clinical indications. PMID- 30296400 TI - Lessons Learned from Implementation of the Food Insecurity Screening and Referral Program at Kaiser Permanente Colorado. AB - Traditionally, health care systems have addressed gaps in patients' diet quality with programs that provide dietary counseling and education, without addressing food security. However, health care systems increasingly recognize the need to address food security to effectively support population health and the prevention and management of diet-sensitive chronic illnesses. Numerous health care systems have implemented screening programs to identify food insecurity in their patients and to refer them to community food resources to support food security. This article describes barriers encountered and lessons learned from implementation and expansion of the Kaiser Permanente Colorado's clinical food insecurity screening and referral program, which operates in collaboration with a statewide organization (Hunger Free Colorado) to manage clinic-to-community referrals. The immediate goals of clinical screening interventions described in this article are to identify households experiencing food insecurity, to connect them to sustainable (federal) and emergency (community-based) food resources, to alleviate food insecurity, and to improve dietary quality. Additional goals are to improve health outcomes, to decrease health care utilization, to improve patient satisfaction, and to better engage patients in their care. PMID- 30296401 TI - TET2: Is a potential gatekeeper for the action of thiazolidinedione in fat cells? PMID- 30296402 TI - High-intensity interval exercise impairs neuroelectric indices of reinforcement learning. AB - A single bout of high-intensity interval exercise (HIIE) improves behavioural measures of cognitive function; however, investigations using event-related potentials (ERPs) to examine the systems that underlie these cognitive improvements are lacking. The reward positivity is a positive-going ERP component that indexes reward processing evoked by 'win' feedback and is a candidate marker of an underlying human reinforcement learning system. While HIIE improves behavioural measures of learning, it is unknown how HIIE affects the amplitude of the reward positivity. Therefore, the purpose of this study was to investigate how HIIE affects reward positivity amplitude in response to reward feedback in university students. Using a single-group randomly assigned counterbalance crossover design, 25 healthy university students performed HIIE and control visits on separate days. Electroencephalographic data was recorded before (pre intervention) and 10 min after (post-intervention) the intervention period while participants played a novel gambling task. The HIIE intervention consisted of 4 separate body-weight exercises totaling 11 min in duration, including rest. The control visit intervention consisted of quietly watching a nature documentary for 11 min. Heart rate (HR) was measured at the same time intervals in both trials. Analysis revealed that HIIE significantly diminished the amplitude of the reward positivity whereas it remained unaffected in the control condition. HR was significantly higher following HIIE compared to control during post-intervention testing. These findings suggest that mechanisms of reinforcement learning are impaired shortly after HIIE cessation, possibly due to persistent, suboptimal arousal as evidenced by elevated HR post-HIIE. PMID- 30296403 TI - Social isolation impairs active avoidance performance and decreases neurogenesis in the dorsomedial telencephalon of rainbow trout. AB - Alterations in the social environment, such as isolating an individual that would normally live in a social group, can generate physiological responses that compromise an individual's capacity to learn. To investigate this, we tested whether social isolation impairs learning skills in the rainbow trout. We show that rainbow trout can achieve an active avoidance (AA) learning program with inter-individual variability. Moreover, c-Fos expression in dorsomedial telencephalon (Dm) correlates with the AA performance, indicating that this structure is involved in this cognitive task. Given that Dm participates in AA learning and this region is under plastic remodelling by addition of new-born neurons, we tested whether social isolation impinges on adult neurogenesis and, consequently, on the Dm cognitive outcome. Trout were reared for four weeks in control or isolated conditions. We found that social isolation diminished the percentage of adult-born neurons that are being incorporated into Dm network. Interestingly, the same isolation treatment also induced a severe deficit in the AA performance. Our results demonstrate a structure-to-function relationship between the Dm and the learning ability in an AA task, indicate that social isolation reduces the incorporation of adult-born neurons into Dm, and show that social isolation impairs the Dm-related cognitive function. PMID- 30296404 TI - Randomized trial of polychromatic blue-enriched light for circadian phase shifting, melatonin suppression, and alerting responses. AB - Wavelength comparisons have indicated that circadian phase-shifting and enhancement of subjective and EEG-correlates of alertness have a higher sensitivity to short wavelength visible light. The aim of the current study was to test whether polychromatic light enriched in the blue portion of the spectrum (17,000 K) has increased efficacy for melatonin suppression, circadian phase shifting, and alertness as compared to an equal photon density exposure to a standard white polychromatic light (4000 K). Twenty healthy participants were studied in a time-free environment for 7 days. The protocol included two baseline days followed by a 26-h constant routine (CR1) to assess initial circadian phase. Following CR1, participants were exposed to a full-field fluorescent light (1 * 1014 photons/cm2/s, 4000 K or 17,000 K, n = 10/condition) for 6.5 h during the biological night. Following an 8 h recovery sleep, a second 30-h CR was performed. Melatonin suppression was assessed from the difference during the light exposure and the corresponding clock time 24 h earlier during CR1. Phase shifts were calculated from the clock time difference in dim light melatonin onset time (DLMO) between CR1 and CR2. Blue-enriched light caused significantly greater suppression of melatonin than standard light ((mean +/- SD) 70.9 +/- 19.6% and 42.8 +/- 29.1%, respectively, p < 0.05). There was no significant difference in the magnitude of phase delay shifts. Blue-enriched light significantly improved subjective alertness (p < 0.05) but no differences were found for objective alertness. These data contribute to the optimization of the short wavelength-enriched spectra and intensities needed for circadian, neuroendocrine and neurobehavioral regulation. PMID- 30296405 TI - Barriers to Help-Seeking Behavior Among Women With Postpartum Depression. AB - Postpartum depression affects approximately 900,000 women annually, but only approximately 6% of these women seek psychological help (Postpartum, Progress, 2016). This lack of help-seeking behavior must be addressed to decrease the negative effects of postpartum depression on maternal and infant outcomes. The purpose of this article is to describe the barriers that prevent women from seeking psychological help and provide suggestions to address these barriers. PMID- 30296406 TI - Aspirin to Prevent Sudden Cardiac Death in Athletes with High Coronary Artery Calcium Scores. AB - While proficient cardiac resuscitation has improved survival following cardiac arrest during road races in Japan, this accomplishment does not address coronary artery disease as the underlying cause of an increasing frequency of cardiac arrest in middle-aged men during marathons and ironman triathlons in the United States since the year 2000. Based on the high prevalence of subclinical coronary artery disease by cardiac computed tomography in endurance athletes with low conventional cardiac risk-factor profiles, we recommend coronary artery calcium scores as a more reliable and independent predictor of incident cardiac events, including death, as validated among adults aged 30-46 years. Scores of over 100 Agatston units indicate a 10-year cardiac risk of 7.5%, at which additional measures for primary prevention are recommended, including aspirin, as shown conclusively to reduce first myocardial infarctions in same-aged men in a prospective double-blind controlled trial. Targeted screening for subclinical coronary atherosclerosis with coronary artery calcium scores is prudent to guide appropriately dosed aspirin use to mitigate the increasing frequency of sports related sudden cardiac death due to plaque rupture. PMID- 30296407 TI - Online Patient Education Materials for Orthognathic Surgery Fail to Meet Readability and Quality Standards. AB - PURPOSE: The purpose of this study was to evaluate the readability and quality of online patient educational materials (PEMs) for orthognathic surgery. MATERIALS AND METHODS: Two internet searches were performed using the search terms orthognathic surgery and jaw surgery. The presence of content related to the risks, benefits, procedure, and postoperative care was recorded. Readability was measured using 4 validated scales: Flesch-Kincaid grade level, Gunning Fog index, Coleman-Liau index, and Simple Measure of Gobbledygook index. Materials were readable if they were written at or below an eighth-grade reading level as recommended by the American Medical Association (AMA) and the National Institutes of Health (NIH). Quality was assessed using 2 metrics: the DISCERN instrument and the Journal of the American Medical Association benchmark criteria. A DISCERN score of 50 was set as the lower limit of acceptable quality. Mann-Whitney U and Fisher exact tests were used to compare the readability, quality, and presence of content between private practice and non-private practice PEMs. RESULTS: Fifty websites were included in the study after removing duplicates and applying exclusion criteria. On average, PEMs were written at a 13.4-grade level (range, 7.8 to 17.3). Nearly every website (n = 49; 98%) mentioned the benefits of surgery; however, very few websites discussed the surgical procedure (n = 12; 24%), postoperative care (n = 10; 20%), and risks or complications (n = 6; 12%). The mean DISCERN score was 25.5 of 80 (range, 18 to 63), and only 2 websites achieved DISCERN scores of acceptable quality. Private practice websites reported less content related to the surgical procedure (P = .03) and had lower DISCERN scores (P = .02). CONCLUSIONS: As a whole, online PEMs for orthognathic surgery failed to meet AMA and NIH readability recommendations and yielded poor quality scores. Increasing the presence of content related to treatment risks and postoperative care will help improve the quality of PEMs. PMID- 30296408 TI - Epigenetic upregulation of miR-126 induced by heat stress contributes to apoptosis of rat cardiomyocytes by promoting Tomm40 transcription. AB - TOMM40 is the channel-forming subunit of a translocase of the mitochondrial outer membrane (TOM) that is essential for protein transport into mitochondria. TOMM40 plays an important role in maintaining normal mitochondrial function. The correlation between occupational thermal exposure and mitochondria dysfunction has been demonstrated; however, nothing is known about the alteration and role of TOMM40 in response to environmental heat stress. In the present study, we showed that environmental thermal exposure upregulated microRNA miR-126, consequently reducing AU-rich element RNA-binding protein 1 (AUF1)-mediated SP1 mRNA degradation and increasing TOMM40 transcription, which in turn decreased the mitochondria membrane potential and apoptosis of cardiomyocytes. Mechanistically, miR-126 upregulation was attributed to heat stress-induced promoter demethylation via elevated TET2 (Tet methylcytosine dioxygenase 2) expression, while SP1 mRNA degradation was caused by decreased translation of AUF1 induced by miR-126. Moreover, TOMM40 transcription was upregulated via increasing its transcription factor SP1 resulting from AUF1 inhibition in the heat stress responses. The results of the present study increased our understanding of the role of miR-126 and TOMM40 in heat stressed cardiomyocytes. PMID- 30296409 TI - PARP inhibition induces Akt-mediated cytoprotective effects through the formation of a mitochondria-targeted phospho-ATM-NEMO-Akt-mTOR signalosome. AB - PURPOSE: The cytoprotective effect of poly(ADP-ribose) polymerase 1 (PARP1) inhibition is well documented in various cell types subjected to oxidative stress. Previously, we have demonstrated that PARP1 inhibition activates Akt, and showed that this response plays a critical role in the maintenance of mitochondrial integrity and in cell survival. However, it has not yet been defined how nuclear PARP1 signals to cytoplasmic Akt. METHODS: WRL 68, HeLa and MCF7 cells were grown in culture. Oxidative stress was induced with hydrogen peroxide. PARP was inhibited with the PARP inhibitor PJ34. ATM, mTOR- and NEMO were silenced using specific siRNAs. Cell viability assays were based on the MTT assay. PARP-ATM pulldown experiments were conducted; each protein was visualized by Western blotting. Immunoprecipitation of ATM, phospho-ATM and NEMO was performed from cytoplasmic and mitochondrial cell fractions and proteins were detected by Western blotting. In some experiments, a continually active Akt construct was introduced. Nuclear to cytoplasmic and mitochondrial translocation of phospho-Akt was visualized by confocal microscopy. RESULTS: Here we present evidence for a PARP1 mediated, PARylation-dependent interaction between ATM and NEMO, which is responsible for the cytoplasmic transport of phosphorylated (thus, activated) ATM kinase. In turn, the cytoplasmic p-ATM and NEMO forms complex with mTOR and Akt, yielding the phospho-ATM-NEMO-Akt-mTOR signalosome, which is responsible for the PARP-inhibition induced Akt activation. The phospho-ATM-NEMO Akt-mTOR signalosome localizes to the mitochondria and is essential for the PARP inhibition-mediated cytoprotective effects in oxidatively stressed cells. When the formation of the signalosome is prevented, the cytoprotective effects diminish, but cells can be rescued by constantly active Akt1, further confirming the critical role of Akt activation in cytoprotection. CONCLUSIONS: Taken together, the data presented in the current paper are consistent with the hypothesis that PARP inhibition suppresses the PARylation of ATM, which, in turn, forms an ATM-NEMO complex, which exits the nucleus, and combines in the cytosol with mTOR and Act, resulting in Act phosphorylation (i.e. activation), which, in turn, produces the cytoprotective action via the induction of Akt-mediated survival pathways. This mechanism can be important in the protective effect of PARP inhibitor in various diseases associated with oxidative stress. Moreover, disruption of the formation or action of the phospho-ATM-NEMO-Akt-mTOR signalosome may offer potential future experimental therapeutic checkpoints. PMID- 30296410 TI - Proteome variation of the rat liver after static cold storage assayed in an ex vivo model. AB - Cold storage is a common procedure for liver preservation in a transplant setting. However, during cold ischemia, the liver suffers molecular alterations that can affect its performance. Also, deleterious mechanisms set forth in the storage phase are exacerbated during reperfusion. This study aimed to identify liver proteins associated with injury during cold storage and/or normothermic reperfusion using the isolated perfused rat liver model. Livers from male rats were subjected to either (1) cold storage for 24 h, (2) ex vivo normothermic reperfusion for 90 min or (3) cold storage for 24 h followed by ex vivo normothermic reperfusion for 90 min. Then, the livers were homogenized and proteins were extracted. Protein expression between each experimental group and the control (freshly resected livers) was compared by two-dimensional (2D) gel electrophoresis. Protein identification was carried out by matrix-assisted laser desorption/ionization time-of-flight spectrometry (MALDI-TOF/TOF) using MASCOT as the search engine. 23 proteins were detected with significantly altered levels of expression among the different treatments, including molecular chaperones, antioxidant enzymes, and proteins involved in energy metabolism. Some of them have been postulated as biomarkers for liver damage while others had been identified in other organs subjected to ischemia and reperfusion injury. The whole data set will be a useful resource for studying deleterious molecular mechanisms that result in diminished liver function during storage and subsequent reperfusion. PMID- 30296411 TI - Properties of phase transition of ice binding protein from Arctic yeast (LeIBP) utilizing differential scanning calorimetry (DSC) and Raman spectroscopy. AB - Ice binding proteins (IBPs) have been attracting significant interest on account of their characteristic of inhibiting ice growth and recrystallization. Owing to their unique characteristics, IBPs have been studied for applications in food, pharmaceuticals, and medicine, as well as from a general scientific point of view. In this study, we have used differential scanning calorimetry (DSC) and Raman spectroscopy as tools to understand the ice binding activity of the Arctic yeast-originating extracellular ice binding glycoprotein (LeIBP) isolated from Leucosporidium sp. AY30. From the DSC results, an increase in the specific heat capacity was confirmed for 1 mg/mL LeIBP, which suggested that additional heat flow was required for the change in temperature. In addition, the temperature corresponding to the phase change of the solution was measured, and Raman spectroscopy was carried out on the frozen and molten phases, respectively. From the results of Raman analysis, we confirmed that the helical vibrations related to the ice binding sites on LeIBP were dramatically suppressed when the LeIBP solution was frozen. Furthermore, principal component analysis (PCA) of the Raman spectra yielded the contrast factor between the freezing and melting states. Both DSC and Raman spectroscopy are widely used to study the ice binding activity and the structural changes associated with molecular vibrations in cryobiology. PMID- 30296412 TI - Light-induced generation and toxicity of docosahexaenoate-derived oxidation products in retinal pigmented epithelial cells. AB - Oxidative cleavage of docosahexaenoate (DHA) in retinal pigmented epithelial (RPE) cells produces 4-hydroxy-7-oxohept-5-enoic acid (HOHA) esters of 2 lysophosphatidylcholine (PC). HOHA-PC spontaneously releases a membrane-permeant HOHA lactone that modifies primary amino groups of proteins and ethanolamine phospholipids to produce 2-(omega-carboxyethyl)pyrrole (CEP) derivatives. CEPs have significant pathological relevance to age-related macular degeneration (AMD) including activation of CEP-specific T-cells leading to inflammatory M1 polarization of macrophages in the retina involved in "dry AMD" and TLR2 dependent induction of angiogenesis that characterizes "wet AMD". RPE cells accumulate DHA from shed rod photoreceptor outer segments through phagocytosis and from plasma lipoproteins secreted by the liver through active uptake from the choriocapillaris. As a cell model of light-induced oxidative damage of DHA phospholipids in RPE cells, ARPE-19 cells were supplemented with DHA, with or without the lipofuscin fluorophore A2E. In this model, light exposure, in the absence of A2E, promoted the generation HOHA lactone-glutathione (GSH) adducts, depletion of intracellular GSH and a competing generation of CEPs. While DHA-rich RPE cells exhibit an inherent proclivity toward light-induced oxidative damage, photosensitization by A2E nearly doubled the amount of lipid oxidation and expanded the spectral range of photosensitivity to longer wavelengths. Exposure of ARPE-19 cells to 1 MUM HOHA lactone for 24 h induced massive (50%) loss of lysosomal membrane integrity and caused loss of mitochondrial membrane potential. Using senescence-associated beta-galactosidase (SA beta-gal) staining that detects lysosomal beta-galactosidase, we determined that exposure to HOHA lactone induces senescence in ARPE-19 cells. The present study shows that products of light-induced oxidative damage of DHA phospholipids in the absence of A2E can lead to RPE cell dysfunction. Therefore, their toxicity may be especially important in the early stages of AMD before RPE cells accumulate lipofuscin fluorophores.

PMID- 30296414 TI - Molecular recognition of lipopolysaccharide by the lantibiotic nisin. AB - Nisin is a lanthionine antimicrobial effective against diverse Gram-positive bacteria and is used as a food preservative worldwide. Its action is mediated by pyrophosphate recognition of the bacterial cell wall receptors lipid II and undecaprenyl pyrophosphate. Nisin/receptor complexes disrupt cytoplasmic membranes, inhibit cell wall synthesis and dysregulate bacterial cell division. Gram-negative bacteria are much more tolerant to antimicrobials including nisin. In contrast to Gram-positives, Gram-negative bacteria possess an outer membrane, the major constituent of which is lipopolysaccharide (LPS). This contains surface exposed phosphate and pyrophosphate groups and hence can be targeted by nisin. Here we describe the impact of LPS on membrane stability in response to nisin and the molecular interactions occurring between nisin and membrane-embedded LPS from different Gram-negative bacteria. Dye release from liposomes shows enhanced susceptibility to nisin in the presence of LPS, particularly rough LPS chemotypes that lack an O-antigen whereas LPS from microorganisms sharing similar ecological niches with antimicrobial producers provides only modest enhancement. Increased susceptibility was observed with LPS from pathogenic Klebsiella pneumoniae compared to LPS from enteropathogenic Salmonella enterica and gut commensal Escherichia coli. LPS from Brucella melitensis, an intra-cellular pathogen which is adapted to invade professional and non-professional phagocytes, appears to be refractory to nisin. Molecular complex formation between nisin and LPS was studied by solid state MAS NMR and revealed complex formation between nisin and LPS from most organisms investigated except B. melitensis. LPS/nisin complex formation was confirmed in outer membrane extracts from E. coli. PMID- 30296415 TI - Oxidatively stressed mitochondria-mimicking membranes: A molecular insight into their organization during apoptosis. AB - Mitochondria are crucially involved in the removal of eukaryotic cells by the intrinsic pathway of programmed cell death (apoptosis). The mitochondrion's outer membrane (MOM) is the platform where this pathway takes place. Upon oxidative stress triggering apoptotic action, the MOM undergoes permeabilization and release of cytochrome c, ultimately causing cell death. This membrane perforation is regulated not only by opposing members of the Bcl-2 protein family meeting at the MOM but also actively the membrane itself. Upon oxidative damage, the membrane undergoes severe reorganization causing an increase in cell death causing apoptotic Bcl-2 proteins. To understand the active role of MOM, we provided a detailed molecular view of its structural and dynamic reorganization upon oxidative stress by solid-state 13C MAS NMR (magic angle spinning nuclear magnetic resonance) accompanied by calorimetric studies. By focusing on MOM-like vesicles doped with oxidized lipid species, direct polarization 13C MAS NMR provided a quantitative overview and identification of all lipid moieties across the membrane. 1H-13C cross polarization and insensitive nuclei enhanced by polarization transfer MAS NMR generated a dynamic - mobile versus restricted - membrane profile. Oxidized phospholipids significantly perturb the structural membrane organization and increase membrane dynamics. These perturbations are not uniformly distributed as the hydrophobic core is reflecting the melting of lipid chains and increase in molecular disorder directly, whereas the interface and headgroup region undergo complex dynamical changes, reflecting increased intra molecular flexibility of these moieties. These changes are potentially crucial in augmenting pro-apoptotic action of proteins like Bax. PMID- 30296416 TI - A 52-Week Study of Dose-Adjusted Subcutaneous Testosterone Enanthate in Oil Self Administered via Disposable Auto-injector. AB - PURPOSE: This open-label, single-arm, dose-blinded, 52-week, registration-phase study evaluated the efficacy and safety of subcutaneous testosterone enanthate auto-injector (SCTE-AI) administered weekly to men with hypogonadism. METHODS: Patients (N=150) were initiated on 75 mg SCTE-AI self-administered weekly. Dose adjustments were made at week 7 to 50, 75, or 100 mg testosterone enanthate (TE) based on week 6 total testosterone (TT) trough concentration. If required, dose adjustments continued through the extended treatment phase. Pharmacokinetic (PK) and clinical laboratory parameters, treatment-emergent adverse events (TEAEs), and injection site reactions were captured. RESULTS: The primary endpoint was met: 92.7% of patients achieved an average TT concentration of 300-1100 ng/dL (553.3 +/- 127.29 ng/dL, mean +/- SD) at week 12. A Cmax of <1500 ng/dL was achieved by 91.3% of patients, and no patients had levels >1800 ng/dL at week 12. Mean TT Ctrough was 487.2 +/- 153.33 ng/dL at week 52. Most patients (>95%) reported no injection-related pain. The most frequently-reported TEAEs were increased hematocrit, hypertension, and increased prostate-specific antigen, which led to discontinuation in 30 men. There were no study drug-related serious AEs. DISCUSSION: Dose-adjusted SCTE-AI demonstrated a steady serum TT PK profile, with small peak and trough fluctuations. SCTE-AI was safe, well tolerated, and virtually painless, indicating that SCTE-AI offers a testosterone delivery system that is a convenient weekly option for treatment of testosterone deficiency. PMID- 30296417 TI - A similarity-based method for prediction of drug side effects with heterogeneous information. AB - Drugs can produce intended therapeutic effects to treat different diseases. However, they may also cause side effects at the same time. For an approved drug, it is best to detect all side effects it can produce. Otherwise, it may bring great risks for pharmaceuticals companies as well as be harmful to human body. It is urgent to design quick and reliable identification methods to detect the side effects for a given drug. In this study, a binary classification model was proposed to predict drug side effects. Different from most previous methods, our model termed the pair of drug and side effect as a sample and convert the original problem to a binary classification problem. Based on the similarity idea, each pair was represented by five features, each of which was derived from a type of drug property. The strong machine learning algorithm, random forest, was adopted as the prediction engine. The ten-fold cross-validation on five datasets with different negative samples indicated that the proposed model yielded a good performance of Matthews correlation coefficient around 0.550 and AUC around 0.8492. In addition, we also analyzed the contribution of each drug property for construction of the model. The results indicated that drug similarity in fingerprint was most related to the prediction of drug side effects and all drug properties gave less or more contributions. PMID- 30296419 TI - Impact of Ethylene Oxide Sterilization of Polymer-Based Prefilled Syringes on Chemical Degradation of a Model Therapeutic Protein During Storage. AB - Materials from prefilled syringe systems-such as silicone oil, tungsten, glass, and rubber-may enhance therapeutic protein aggregation and particle formation. Also, the sterilization method used for syringes may impact aggregation and chemical degradation of biologics during storage. Syringes are generally sterilized by radiation, ethylene oxide gas (EO), or steam. Among the sterilization methods, EO has the potential to cause chemical degradation by the formation of adducts with susceptible amino acid residues in the protein. In this study, EO- and steam-sterilized syringes were compared to determine the influence of residual EO on human serum albumin (HSA) degradation. Although the amount of residual EO in the EO-sterilized syringes was less than 220 MUg/syringe, well below the International Organization for Standardization limit, EO adduction to cysteine (Cys) and methionine (Met) in HSA was observed by liquid chromatography and mass spectrometry analysis. The EO adduct ratio of HSA stored for 2 weeks in EO-sterilized syringes was about 45%. In contrast, no chemical degradation was observed in HSA formulation stored in steam-sterilized syringes. Because of the propensity of EO to readily form adducts with proteins, an alternative to EO sterilization should be used for prefilled syringes that will be used for therapeutic protein products. PMID- 30296418 TI - Adult Outpatients With Acute Cough Due to Suspected Pneumonia or Influenza: CHEST Guideline and Expert Panel Report. AB - BACKGROUND: Patients commonly present to primary care services with upper and lower respiratory tract infections, and guidelines to help physicians investigate and treat acute cough due to suspected pneumonia and influenza are needed. METHODS: A systematic search was carried out with eight patient, intervention, comparison, outcome questions related to acute cough due to suspected pneumonia or influenza. RESULTS: There was a lack of randomized controlled trials in the setting of outpatients presenting with acute cough due to suspected pneumonia or influenza who were not hospitalized. Both clinical suggestions and research recommendations were made on the evidence available and CHEST Expert Cough Panel advice. CONCLUSIONS: For outpatient adults with acute cough due to suspected pneumonia, we suggest the following clinical symptoms and signs are suggestive of pneumonia: cough; dyspnea; pleural pain; sweating, fevers, or shivers; aches and pains; temperature >= 38 degrees C; tachypnea; and new and localizing chest examination signs. Those suspected of having pneumonia should undergo chest radiography to improve diagnostic accuracy. Although the measurement of C reactive protein levels strengthens both the diagnosis and exclusion of pneumonia, there was no added benefit of measuring procalcitonin levels in this setting. We suggest that there is no need for routine microbiological testing. We suggest the use of empiric antibiotics according to local and national guidelines when pneumonia is suspected in settings in which imaging cannot be performed. Where there is no clinical or radiographic evidence of pneumonia, we do not suggest the routine use of antibiotics. There is insufficient evidence to make recommendations for or against specific nonantibiotic, symptomatic therapies. Finally, for outpatient adults with acute cough and suspected influenza, we suggest that initiating antiviral treatment (according to Centers for Disease Control and Prevention advice) within 48 hours of symptoms could be associated with decreased antibiotic use and hospitalization and improved outcomes. PMID- 30296420 TI - Dermal CD207-Negative Migratory Dendritic Cells Are Fully Competent to Prime Protective, Skin Homing Cytotoxic T-Lymphocyte Responses. AB - Dendritic cells (DCs) are important inducers and regulators of T-cell responses. They are able to activate and modulate the differentiation of CD4+ and CD8+ T cells. In the skin, there are at least five phenotypically distinct DC subpopulations that can be distinguished by differential expression of the cell surface markers CD207, CD103, and CD11b. Previous studies have suggested that dermal CD11b-CD207+ conventional type 1 DCs are indispensable for the priming of a skin homing cytotoxic T-lymphocyte response. However, conventional type 1 DCs are also the only skin DC subset capable of cross-presenting exogenous antigens on major histocompatibility complex class I. Thus, it remained unclear whether for antigens that do not require cross-presentation, such as viruses that infect DCs, other DC subtypes in the skin can contribute to cytotoxic T-lymphocyte priming. To address this question, we used a transgenic mouse model that allows inducible expression and presentation of a model antigen on selected subsets of dermal DCs. We show that for antigens presented via the conventional major histocompatibility complex class I presentation pathway, CD207- dermal DCs are fully competent to prime a skin homing cytotoxic T-lymphocyte response that is capable of protection against a local virus challenge and gives rise to skin resident memory CD8+ T cells. PMID- 30296421 TI - Outcomes of valve repair for degenerative disease in patients with mitral annular calcification. AB - BACKGROUND: The predictors for the development of MAC in degenerative mitral valve disease and the effect it may have on patient- and valve-related outcomes require further evaluation. METHODS: Between 1/2002 and 12/2015, 627 patients underwent mitral valve surgery for degenerative disease. MAC was seen in 75 (12%) patients; 73 (97%) underwent valve repair (6 without annuloplasty ring implantation) while 2 (3%) underwent valve replacement after an unsuccessful repair attempt. RESULTS: MAC was linked to patient age, female gender and degenerative disease subtype. Early mortality was comparable between patients with and without MAC [3/75 (4%) vs. 10/552 (2%), P=0.20]. In patients with MAC, 1/3 deaths was directly related to annular decalcification and reconstruction. Early repair failure was more common in patients with MAC [8/75 (11%) vs. 17/552 (3%), P=0.006]. During follow-up, no differences in overall survival or freedom from late reintervention were observed. However, at 8 years after surgery, freedom from recurrent mitral regurgitation was worse in patients with MAC. In these patients, repair failure was linked to non-use of ring annuloplasty. For patients with MAC in whom annular decalcification and annuloplasty were performed, repair durability was comparable to patients without MAC. CONCLUSIONS: Mitral valve surgery in degenerative disease accompanied by MAC is safe. Optimal surgical strategy includes annular decalcification (when this would prevent implantation of an annuloplasty ring) and ring annuloplasty and will lead to results similar to patients without MAC. However, when the annulus is not addressed, repair performance is hampered. For these patients, alternative repair techniques should be explored in the future. PMID- 30296422 TI - Comparison of Laparoscopic Versus Open Surgical Management of Morgagni Hernia. AB - BACKGROUND: Morgagni hernias are rare congenital diaphragmatic hernias that often do not become clinically significant until adulthood. The purpose of this study was to characterize the preoperative findings and describe surgical outcomes of Morgagni hernia repair based on operative approach. METHODS: Charts of patients who underwent repair of a Morgagni hernia were retrospectively reviewed from 1987 to 2015. Medical records were reviewed for demographics, symptoms, comorbidities, surgical approach, hospital course, complications, and preoperative imaging. RESULTS: Forty-three cases were identified, 23 male and 20 female. Median age was 50.4 years, and median body mass index was 33.1 kg/m2. Most common presenting symptoms were respiratory (35.7%) and gastrointestinal (28.6%). Although 83.3% of cases were newly diagnosed, none required emergent repair. Preoperative imaging demonstrated an average hernia size of 8.2 cm. Surgical approaches included laparotomy (62.8%), laparoscopic (23.3%), and thoracotomy (14%). Primary hernia repair was most common (72%). Comparing laparotomy, thoracotomy, and laparoscopic approaches, mesh repair was more common with laparoscopy (p = 0.005), operative time was shortest with laparotomy (p = 0.029), and hospital length of stay was shortest with laparoscopy (p = 0.024). The most common complication was incisional/port site hernia, with no statistical significance between surgical approaches. There was one Morgagni hernia recurrence. CONCLUSIONS: Morgagni hernias often present with respiratory and gastrointestinal symptoms and require repair. All cases in our series were repaired electively. Regardless of approach recurrence rate was low (2.3%) and complication rate was similar between laparoscopic, laparotomy, and thoracotomy. Given the shorter length of stay with similar recurrence rates, a laparoscopic approach is a viable option for repair of Morgagni hernia. PMID- 30296423 TI - Intraoperative Near-Infrared Fluorescence-Guided Peripheral Lung Tumor Localization in Rabbit Models. AB - BACKGROUND: A novel liposomal nanoparticle, CF800, that co-encapsulates indocyanine green for near-infrared (NIR) imaging and iohexol for computed tomography (CT) imaging has shown preferential tumor accumulation after intravenous injection by the enhanced permeability and retention effect. We hypothesized that CF800-enhanced NIR imaging would facilitate intraoperative localization of small lung nodules. METHODS: A rabbit VX2 lung tumor model was implemented. CF800 was injected intravenously, followed by sequential CT acquisitions to track the biodistribution of CF800. Eleven rabbits were used for NIR fluorescence evaluation after thoracotomy at time points until 7 days after injection by using a NIR fluorescence thoracoscope in vivo. Organs of interests were removed for ex vivo analysis by using NIR imaging. Tumor-to-background (inflated lung) ratio was calculated and compared among the time points. RESULTS: Both CT and NIR imaging indicated enhanced accumulation of CF800 within the VX2 tumor. NIR image analysis revealed the highest tumor-to-background ratio on days 4 and 5. High background at day 2 and low tumor signal at day 7 prevented distinct demarcation. Metastatic pulmonary small nodules (less than 2 mm in diameter) were successfully visualized by NIR imaging on day 4. However, NIR signal penetration was limited, resulting in localization failure for the few tumors deep (>0 mm) to the lung surface. CONCLUSIONS: NIR image-guided localization of small lung nodules appears to be feasible under certain conditions. However, further refinement will be required to increase tumor signal intensity and to reduce background signal from normal lung parenchyma, which is at least in part a consequence of persistent CF800 in the vasculature. PMID- 30296424 TI - Initial Experiences With Robotic Single-Site Thoracic Surgery for Mediastinal Masses. AB - BACKGROUND: The da Vinci Single-Site platform (Intuitive Surgical, Mountain View, CA) has been applied in many fields of surgery, but use of this single-site platform in thoracic surgery has not been reported. This study reported our experiences and surgical outcomes with robotic single-site surgery in the field of thoracic surgery. METHODS: We retrospectively reviewed 14 patients who underwent robotic single-site thoracic surgery at 2 different institutions. RESULTS: All 14 cases were successfully completed, without conversion to conventional multiport robotic surgery. The most frequent diagnoses were thymic cyst (n = 4) and pericardial cyst (n = 3). The median largest mass size was 4.1 cm (range, 2.0 to 6.5 cm). The median operation time was 105 minutes (range, 27 to 185 minutes). After the operation, pleural effusion occurred in 1 patient (case 7) on the side on which the operation was performed but was managed with conservative treatment. The median duration of chest tube stay was 2 days (range, 1 to 3 days), and hospital stay was 4 days (range, 3 to 11 days). The median peak pain score after the operation was 3 (range, 1 to 7). Compared with thoracoscopic single-port surgery, robotic single-site thoracic surgery showed a longer operative time and higher cost. CONCLUSIONS: This study demonstrated that robotic single-site thoracic surgery for mediastinal masses is a safe and feasible procedure. Although this study reports the initial series and the cases were relatively simple, more advanced and complex procedures could be done with the advent of new technology in the near future. PMID- 30296425 TI - Ventricular Assist Device Support: Single Pediatric Institution Experience Over Two Decades. AB - BACKGROUND: We sought to review our single institutional experience with pediatric ventricular assist device (VAD) support over the last two decades, with an aim to improve our current management and to gain an insight into the future direction. METHODS: A retrospective review was conducted on all patients that had undergone VAD support between 1996 and 2017. Outcomes were analyzed based on the type of VADs, whether temporary or durable devices. Primary endpoints were positive outcomes including bridge-to-transplantation (BTT), bridge-to-recovery (BTR), alive on device, and bridge-to-bridge to another VAD (BTB) or negative outcomes including death during VAD support or in-hospital death following BTR. PediMACS definition was utilized to classify adverse events. RESULTS: Overall, 201 VADs were implanted in 159 patients, with 82 (41%) and 119 (59%) being temporary and durable support, respectively. There has been a trend toward an increasing annual implant volume both with temporary and durable VADs. 80% (66/82) of temporary support achieved positive outcomes, with BTR (53%, 35/66) and BTB (38%, 25/66) being the predominant outcomes. 84% (100/119) of durable support achieved positive outcomes, with BTT (66%, 78/119) being the leading destination. The most notable change during the study period was the introduction of implantable continuous-flow VADs, resulting in outpatient management becoming a routine practice. While none were discharged on VAD support before 2004, 85% were discharged on VADs with discharge capability after 2013. CONCLUSIONS: The present study has demonstrated the evolutional changes of pediatric VAD support and their impact on clinical outcomes over the last two decades. PMID- 30296426 TI - Measuring What Matters. PMID- 30296427 TI - The cytosolic Ca2+ concentration in acutely dissociated subfornical organ (SFO) neurons of rats: spontaneous Ca2+ oscillations and Ca2+ oscillations induced by picomolar concentrations of angiotensin II. AB - Characteristics of subfornical organ (SFO) neurons were examined by measuring the cytosolic Ca2+ concentration ([Ca2+]i) in acutely dissociated neurons of the rat. SFO neurons, defined by the responsiveness to 50 mM K+ (n=67) responded to glutamate (86%), angiotensin II (AII) (50%), arginine vasopressin (AVP) (66%) and/or carbachol (CCh) (61%), at their maximal concentrations, with marked increases in [Ca2+]i. More than a half (174/307) of SFO neurons examined exhibited spontaneous Ca2+ oscillations, while the remainder showed a relatively stable baseline under unstimulated conditions. Spontaneous Ca2+ oscillations were suppressed when extracellular Ca2+ was removed and were inhibited when extracellular Na+ was replaced with equimolar Nmethyl- D-glucamine. Ca2+ oscillations were unaffected by the inhibitor of Ca2+-dependent ATPases cyclopiazonic acid, the N-type Ca2+ channel blocker omega-conotoxin GVIA and the P/Q-type Ca2+ channel blocker omega-agatoxin IVA, but significantly inhibited by the high-voltage-activated Ca2+ channel blocker Cd2+ and the L-type Ca2+ channel blocker nicardipine. Ca2+ oscillations were also completely arrested by the voltage-gated Na+ channel blocker tetrodotoxin in 50 % of SFO neurons but only partially in the remaining neurons. These results suggest that SFO neurons exhibit spontaneous membrane Ca2+ oscillations that are dependent in part on Ca2+ entry through L-type Ca2+ channels, whose activation may result from burst firing. Moreover, AII at picomolar concentrations induced Ca2+ oscillations in neurons showing no spontaneous Ca2+ oscillations, while spontaneous Ca2+ oscillations were arrested by gamma-aminobutyric acid (10 MUM), suggesting that rises in [Ca2+]i during Ca2+ oscillations may play an important role in the modulation of SFO neuron function. PMID- 30296428 TI - Cell type- and pathway-specific synaptic regulation of orexin neurocircuitry. AB - Orexin-expressing neurons are located exclusively in the lateral hypothalamic and perifornical areas and exhibit complex connectivity. The intricate wiring pattern is evident from a diverse function for orexin neurons in regulating many physiological processes and behaviors including sleep, metabolism, circadian cycles, anxiety, and reward. Nevertheless, the precise synaptic and circuitry level mechanisms mediating these processes remain enigmatic, partially due to the wide spread connectivity of the orexin system, complex neurochemistry of orexin neurons, and previous lack of suitable tools to address its complexity. Here we summarize recent advances, focusing on synaptic regulatory mechanisms in the orexin neurocircuitry, including both the synaptic inputs to orexin neurons as well as their downstream targets in the brain. A clear and detailed elucidation of these mechanisms will likely provide novel insight into how dysfunction in orexin-mediated signaling leads to human disease and may ultimately be treated with more precise strategies. PMID- 30296429 TI - Plasma Levels of Brain-Derived Neurotrophic Factor in Patients with Parkinson Disease: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Brain-derived neurotrophic factor (BDNF) is an abundant neurotrophin in the adult brain. Serum BDNF levels might be used as a proxy for its central expression. Considering conflicting reports, we aimed to answer "How do serum/CSF levels of BDNF change in patients with PD?". METHODS: We conducted a comprehensive search in MEDLINE, EMBASE and SCOPUS databases including 12 eligible studies. Five studies compared BDNF in serum of PD patients versus healthy controls (HC) and 3 studies provided BDNF levels in sera of non-depressed and depressed PD patients (NDPD and DPD). Review Manager and Software version 3.0 were used for meta-analysis and meta-regressions. Mean difference (MD) was used for measurement of effect size. RESULTS: PD patients had reduced serum BDNF levels compared to HC (MD=-2.99 ng/mL). Serum BDNF was highest in DPD patients compared to HC (MD=-4.83 ng/mL), with no difference between DPD and NDPD patients in serum BDNF levels. Among co-variates that were eligible for meta-regression, age, sex, and Hoehn and Yahr (H&Y) motor stage had significant positive associations with the effect size in the difference of serum BDNF between patients and HC. CONCLUSIONS: PD patients had reduced serum BDNF levels compared to HC, regardless of presence of co-morbid depression. PD is at least equally effective in reducing serum BDNF levels as depression. Motor progression predicts serum BDNF downregulation in PD. Acute exercise improves motor function and depressive symptoms in PD probably via BDNF upregulation. The paradoxical rise in serum BDNF in advance PD is probably compensatory in nature. PMID- 30296430 TI - Long-Term Deficits in Risky Decision-Making after Traumatic Brain Injury on a Rat Analog of the Iowa Gambling Task. AB - Traumatic brain injury (TBI) affects 2.8 million people annually in the United States, with significant populations suffering from ongoing cognitive dysfunction. Impairments in decision-making can have major implications for patients and their caregivers, often enduring for years to decades, yet are rarely explored in experimental TBI. In the current study, the Rodent Gambling Task (RGT), an Iowa Gambling Task analog, was used to assess risk-based decision making and motor impulsivity after TBI. During testing, rats chose between options associated with different probabilities of reinforcement (sucrose) or punishment (timeout). To determine effects of TBI on learned behaviors versus the learning process, rats were trained either before, or after, a bilateral frontal controlled cortical impact TBI, and then assessed for 12 weeks. To evaluate the degree to which monoamine systems, such as dopamine, were affected by TBI, rats were given an amphetamine challenge, and behavior recorded. Injury immediately and chronically decreased optimal decision-making, and biased rats towards both riskier, and safer (but suboptimal) choices, regardless of prior learning history. TBI also increased motor impulsivity across time, reflecting ongoing neural changes. Despite these similarities in trained and acquisition rats, those that learned the task after injury demonstrated reduced effects of amphetamine on optimal decision-making, suggesting a lesser role of monoamines in post-injury learning. Amphetamine also dose-dependently reduced motor impulsivity in injured rats. This study opens up the investigation of psychiatric-like dysfunction in animal models of TBI and tasks such as the RGT will be useful in identifying therapeutics for the chronic post-injury period. PMID- 30296431 TI - Factors Associated With Recurrence of Primary Biliary Cholangitis After Liver Transplantation and Effects on Graft and Patient Survival. AB - BACKGROUND & AIMS: Primary biliary cholangitis (PBC) frequently recurs after liver transplantation. We evaluated risk factors associated with recurrence of PBC and its effects on patient and graft survival in a multicenter, international cohort (the Global PBC Study Group). METHODS: We collected demographic and clinical data from 785 patients (89% female) with PBC who underwent liver transplantation (mean age, 54 +/- 9 years) from February 1983 through June 2016, among 13 centers in North America and Europe. Results from biochemical tests performed within 12 months of liver transplantation were analyzed to determine whether markers of cholestasis could identify patients with recurrence of PBC (based on histologic analysis). Patients were followed for a median 6.9 years (interquartile range, 6.1-7.9 years). RESULTS: PBC recurred in 22% of patients after 5 years and 36% after 10 years. Age at diagnosis <50 years (hazard ratio [HR], 1.79; 95% CI, 1.36-2.36; P < .001), age at liver transplantation <60 years (HR, 1.39; 95% CI, 1.02-1.90; P = .04), use of tacrolimus (HR, 2.31; 95% CI, 1.72 3.10; P < .001), and biochemical markers of severe cholestasis (bilirubin >=100 MUmol or alkaline phosphatase >3-fold the upper limit of normal) at 6 months after liver transplantation (HR, 1.79; 95% CI, 1.16-2.76; P = .008) were associated with higher risk of PBC recurrence, whereas use of cyclosporine reduced risk of PBC recurrence (HR, 0.62; 95% CI, 0.46-0.82; P = .001). In multivariable Cox regression with time-dependent covariate, recurrence of PBC significantly associated with graft loss (HR, 2.01; 95% CI, 1.16-3.51; P = .01) and death (HR, 1.72; 95% CI, 1.11-2.65; P = .02). CONCLUSIONS: Younger age at the time of diagnosis with PBC or at liver transplantation, tacrolimus use, and biochemical markers of cholestasis after liver transplantation are associated with PBC recurrence. PBC recurrence reduces odds of graft and patient survival. Strategies are needed to prevent PBC recurrence or reduce its negative effects. PMID- 30296433 TI - Acute Respiratory Failure During Systemic Chemotherapy. PMID- 30296432 TI - Accuracy of the Narrow-Band Imaging International Colorectal Endoscopic Classification System in Identification of Deep Invasion in Colorectal Polyps. AB - BACKGROUND & AIMS: T1 colorectal polyps with at least 1 risk factor for metastasis to lymph node should be treated surgically and are considered endoscopically unresectable. Optical analysis, based on the Narrow-Band Imaging International Colorectal Endoscopic (NICE) classification system, is used to identify neoplasias with invasion of the submucosa that require endoscopic treatment. We assessed the accuracy of the NICE classification, along with other morphologic characteristics, in identifying invasive polyps that are endoscopically unresectable (have at least 1 risk factor for metastasis to lymph node). METHODS: We performed a multicenter, prospective study of data collected by 58 endoscopists, from 1634 consecutive patients (examining 2123 lesions) at 17 university and community hospitals in Spain from July 2014 through June 2016. All consecutive lesions >10 mm assessed with narrow-band imaging were included. The primary end point was the accuracy of the NICE classification for identifying lesions with deep invasion, using findings from histology analysis as the reference standard. Conditional inference trees were fitted for the analysis of diagnostic accuracy. RESULTS: Of the 2123 lesions analyzed, 89 (4.2%) had features of deep invasion and 91 (4.3%) were endoscopically unresectable. The NICE classification system identified lesions with deep invasion with 58.4% sensitivity (95% confidence interval [CI], 47.5-68.8), 96.4% specificity (95% CI, 95.5-97.2), a positive-predictive value of 41.6% (95% CI, 32.9-50.8), and a negative-predictive value of 98.1% (95% CI, 97.5-98.7). A conditional inference tree that included all variables found the NICE classification to most accurately identify lesions with deep invasion (P < .001). However, pedunculated morphology (P < .007), ulceration (P = .026), depressed areas (P < .001), or nodular mixed type (P < .001) affected accuracy of identification. Results were comparable for identifying lesions that were endoscopically unresectable. CONCLUSIONS: In an analysis of 2123 colon lesions >10 mm, we found the NICE classification and morphologic features identify those with deep lesions with >96% specificity-even in non-expert hands and without magnification. ClinicalTrials.gov number NCT02328066. PMID- 30296434 TI - Serologic Response to Helicobacter pylori Proteins Associated With Risk of Colorectal Cancer Among Diverse Populations in the United States. AB - BACKGROUND & AIMS: Previous studies reported an association of the bacteria Helicobacter pylori, the primary cause of gastric cancer, and risk of colorectal cancer (CRC). However, these findings have been inconsistent, appear to vary with population characteristics, and may be specific for virulence factor VacA. To more thoroughly evaluate the potential association of H pylori antibodies with CRC risk, we assembled a large consortium of cohorts representing diverse populations in the United States. METHODS: We used H pylori multiplex serologic assays to analyze serum samples from 4063 incident cases of CRC, collected before diagnosis, and 4063 matched individuals without CRC (controls) from 10 prospective cohorts for antibody responses to 13 H pylori proteins, including virulence factors VacA and CagA. The association of seropositivity to H pylori proteins, as well as protein-specific antibody level, with odds of CRC was determined by conditional logistic regression. RESULTS: Overall, 40% of controls and 41% of cases were H pylori-seropositive (odds ratio [OR], 1.09; 95% CI, 0.99 1.20). H pylori VacA-specific seropositivity was associated with an 11% increased odds of CRC (OR, 1.11; 95% CI, 1.01-1.22), and this association was particularly strong among African Americans (OR, 1.45; 95% CI, 1.08-1.95). Additionally, odds of CRC increased with level of VacA antibody in the overall cohort (P = .008) and specifically among African Americans (P = .007). CONCLUSIONS: In an analysis of a large consortium of cohorts representing diverse populations, we found serologic responses to H pylori VacA to associate with increased risk of CRC risk, particularly for African Americans. Future studies should seek to understand whether this marker is related to virulent H pylori strains carried in these populations.

Endoscopic mucosal resection (EMR) is performed to remove large laterally spreading colonic lesions, which have a high risk of progression to CRC. Endoscopically invisible micro-adenomas at the margins of the EMR site might contribute to adenoma recurrence, which occurs in 15%-30% of patients who undergo surveillance. We aimed to determine the efficacy of adjuvant thermal ablation of the EMR mucosal defect margin in reducing polyp recurrence. METHODS: We performed a prospective study of 390 patients with large laterally spreading colonic lesions (>= 20 mm, n = 416) referred for EMR at 4 tertiary centers in Australia. After complete lesion excision by EMR, lesions were randomly assigned to thermal ablation of the post-EMR mucosal defect margin (n = 210) or no additional treatment (controls, n = 206). We performed surveillance colonoscopies with standardized photo documentation and biopsies of the scar after 5-6 months. Patient, procedure and lesion characteristics were similar between the groups. The primary endpoint was detection of lesion recurrence at first surveillance colonoscopy. RESULTS: A significantly lower proportion of patients who received thermal ablation of the post-EMR mucosal defect margin had evidence of recurrence at first surveillance colonoscopy (10/192, 5.2%) than controls (37/176, 21.0%) (P < .001). The relative risk of recurrence in the thermal ablation group was 0.25 compared with the control group (95% CI, 0.13-0.48). Rates of adverse events were similar between the groups. CONCLUSIONS: In a multi-center randomized trial, thermal ablation of the post-EMR mucosal defect margin significantly reduced polyp recurrence at SC1, compared with no additional treatment. Routine implementation of this simple and safe technique could increase the utility of EMR, decrease surveillance burdens, and reduce morbidity and mortality from CRC.

AB - BACKGROUND AND AIMS: Cells in pancreatic ductal adenocarcinoma (PDAC) undergo autophagy, but its effects vary with tumor stage and genetic factors. We investigated the consequences of varying levels of the autophagy-related 5 (Atg5) protein on pancreatic tumor formation and progression. METHODS: We generated mice that express oncogenic Kras in primary pancreatic cancer cells and have homozygous disruption of Atg5 (A5;Kras) or heterozygous disruption of Atg5 (A5+/ ;Kras), and compared them with mice with only oncogenic Kras (controls). Pancreata were analyzed by histology and immunohistochemistry. Primary tumor cells were isolated and used to perform transcriptome, metabolome, intracellular calcium, extracellular cathepsin activity, and cell migration and invasion analyses. The cells were injected into wild-type littermates, and orthotopic tumor growth and metastasis were monitored. Atg5 was knocked down in pancreatic cancer cell lines using small hairpin RNAs; cell migration and invasion were measured, and cells were injected into wild-type littermates. PDAC samples were obtained from independent cohorts of patients and protein levels were measured on immunoblot and immunohistochemistry; we tested the correlation of protein levels with metastasis and patient survival times. RESULTS: A5+/-;Kras mice, with reduced Atg5 levels, developed more tumors and metastases, than control mice, whereas A5;Kras mice did not develop any tumors. Cultured A5+/-;Kras primary tumor cells were resistant to induction and inhibition of autophagy, had altered mitochondrial morphology, compromised mitochondrial function, changes in intracellular Ca2+ oscillations, and increased activity of extracellular cathepsin L and D. The tumors that formed in A5+/-;Kras mice contained greater numbers of type 2 macrophages than control mice, and primary A5+/-;Kras tumor cells had up-regulated expression of cytokines that regulate macrophage chemoattraction and differentiation into M2 macrophage. Knockdown of Atg5 in pancreatic cancer cell lines increased their migratory and invasive capabilities, and formation of metastases following injection into mice. In human PDAC samples, lower levels of ATG5 associated with tumor metastasis and shorter survival time. CONCLUSIONS: In mice that express oncogenic Kras in pancreatic cells, heterozygous disruption of Atg5 and reduced protein levels promotes tumor development, whereas homozygous disruption of Atg5 blocks tumorigenesis. Therapeutic strategies to alter autophagy in PDAC should consider the effects of ATG5 levels to avoid the expansion of resistant and highly aggressive cells.

AB - BACKGROUND: International recommendations on high-sensitivity cardiac troponin (hs-cTn) testing recommend that laboratories select only one sample type for testing. We evaluated the Siemens ADVIA Centaur hs-cTnI assay in serum and thereby provide information on imprecision, long-term storage stability, freeze thaw stability, method comparison to other hs-cTnI assays, and clinical performance. METHODS: Patients with chest pain onset <6 h who already had Roche hs-cTnT, Beckman hs-cTnI and Abbott hs-cTnI results recorded and had non-thawed and frozen serum aliquots formed the study population (n = 134 patients with 305 serum aliquots obtained at either 0, 3 or 6 h stored below -70 degrees C since 2003) for measurement with the Siemens hs-cTnI assay in 2018. Receiver-operating characteristic curve analyses for myocardial infarction (MI) using the highest obtained hs-cTn concentration was performed. Additional comparison testing on serum samples stored frozen (at -70 degrees C for <1 month in 2018) for the Siemens and Abbott hs-cTnI assays were performed, as well as precision testing in serum pools and freeze-thaw stability testing. RESULTS: The Siemens hs-cTnI assay had an area under the curve (AUC) of 0.978 (95%CI: 0.937-0.996) for MI in the study cohort (Roche hs-cTnT AUC = 0.965 and Abbott AUC = 0.973). The Siemens hs cTnI assay yielded higher cTnI concentrations than the other hs-cTn assays, with the same proportional bias (slope = 1.4) between the Siemens and Abbott hs-cTnI assays obtained from serum samples collected in 2003 and 2018. Over 3 months, a low serum pool of 3.5 ng/l achieved a CV of 20% (SD = 0.7, n = 42) and a high serum pool of 820 ng/l achieved a CV of 2.3% (SD = 20, n = 42). Three different serum pools recovered within 10% from baseline concentration after 5 freeze-thaw cycles for the Siemens hs-cTnI assay. CONCLUSIONS: In serum, the Siemens ADVIA Centaur hs-cTnI assay had excellent clinical performance for MI in an early chest pain onset population, acceptable precision at normal and highly elevated cTnI concentrations, long-term storage stability (15 y storage below -70 degrees C) and acceptable freeze-thaw stability, all of which supports serum as an acceptable sample type to use in clinical studies and in clinical practice. PMID- 30296441 TI - Characterization of PLAC(r) tests in the quantization of lipoprotein associated phospholipase A2 for assessment of cardiovascular diseases. AB - BACKGROUND: PLAC(r) mass test (diaDexus, Inc.) does not detect all Lp-PLA2 proteins in the circulation. The total circulating Lp-PLA2 mass can be quantized by using the CHAPS modified PLAC(r) mass test. To compare the difference of the PLAC(r) mass, CHAPS modified PLAC(r) mass and PLAC(r) activity tests in risk assessment of CVD, the 3 Lp-PLA2 quantization methods were characterized using a collection of serum and plasma from CVD patents and matched non-symptomatic controls. Improvement on risk assessment for ischemic stroke by Lp-PLA2 and lipids were also investigated. METHODS: Ninety one human sera and plasma from elderly patients with first CVD incidents and 78 matched controls were collected at clinics. Lp-PLA2 was assessed by PLAC(r) mass, CHAPS modified PLAC(r) mass and PLAC(r) activity tests and data were subjected to statistical analyses. Correlation with lipid cholesterols or Apo proteins was compared for all formats of PLAC(r) tests. Ratios of Lp-PLA2 by different PLAC(r) tests to different lipids were assessed for synergistic enhancement in the indication of ischemic stroke. RESULTS: The PLAC(r) mass test was superior to other formats of PLAC(r) tests in the assessment of CVD and is independent of lipids. The Lp-PLA2 by the CHAPS modified PLAC(r) mass test has no separation between the CVD and control groups. CONCLUSIONS: Both PLAC(r) mass and PLAC(r) activity tests are effective but the CHAPS modified PLAC(r) mass test has no or less utility in the risk assessment of CVD. The ratio of Lp-PLA2 by either PLAC(r) mass or PLAC(r) activity over ApoA1 or (Apo A1 + Apo B) synergistically enhance the risk assessment power for ischemic stroke. PMID- 30296442 TI - Comprehensive assessment of biotin interference in immunoassays. AB - BACKGROUND: Biotinylated antibodies and analogues are currently used in many immunoassays while biotin is widely used as a dietary supplement. Thus, biotin interference is an emerging issue for clinical laboratories. METHODS: Various concentrations of biotin solutions were prepared using pooled patient serum samples. All analytes were measured by sandwich or competitive immunoassay on the Roche Cobas 8000 e602 platform. RESULTS: Some of the sandwich immunoassay results were falsely decreased to different extents by different biotin levels, while some of the competitive immunoassay results were falsely increased. The most notable false reductions were in high-sensitivity troponin T, thyroid-stimulating hormone, and follicle-stimulating hormone results, while the most notable false increases were in triiodothyronine and vitamin D results. Other immunoassay results were also affected to some extent by biotin interference. CONCLUSIONS: Biotin can interfere in immunoassays and result in aberrant test results. Clinicians should use caution in interpreting abnormal results in patients who ingest biotin. PMID- 30296443 TI - Apelin/APJ system: A novel promising target for anti-aging intervention. AB - Apelin, an endogenous ligand for the G protein-coupled receptor APJ, is widely expressed in various organs. Recent research has indicated that the Apelin/APJ system plays an important role in aging. Apelin and APJ receptor expression are down-regulated with increasing age. In murine models, Apelin and APJ knockouts exhibit accelerated senescence whereas Apelin-restoration results in enhanced vigor and rejuvenated behavioral and circadian phenotypes. Furthermore, aged Apelin knockout mice develop progressive impairment of cardiac contractility associated with systolic dysfunction. Apelin is crucial to maintain cardiac contractility in aging. Moreover, the Apelin/APJ system appears to be involved in regulation of renin-angiotensin-aldosterone system (RAAS), apoptosis, inflammation and oxidative stress which promotes aging. Likewise, the Apelin/APJ system regulates autophagy, stem cells and the sirtuin family thus contributing to anti-aging. In this review, we describe the relationship between Apelin/APJ system and aging. We elaborate on the role of the Apelin/APJ system in aging stimulators, aging inhibitors and age-related diseases such as obesity, diabetes and cardiovascular disease. We conclude that Apelin/APJ system might become a novel promising therapeutic target for anti-aging. PMID- 30296444 TI - Plasma metabolomic profiling distinguishes right-sided from left-sided colon cancer. AB - BACKGROUND: Many studies have demonstrated that right-sided colon cancer (RCC) has a higher mortality rate and worse prognosis than left-sided colon cancer (LCC). However, the underlying biological mechanism that can account for these differences is unclear. METHODS: In this study, plasma metabolic profiles in 147 LCC patients and 105 RCC patients were systematically analyzed by the ultra high performance liquid chromatography quadruple time-of-flight mass spectrometry (UHPLC-QTOF/MS) platform in conjunction with univariate and multivariate statistical analysis. RESULTS: Metabolic signatures revealed considerable differences between patients with RCC and LCC, and clear separations were observed between the two groups in partial least-squares discriminant analysis score plots. In total, six metabolites were identified as potential metabolite markers for tumor location in RCC compared with LCC, including upregulated trimethylamine N-oxide and indoxyl sulfate, and downregulated anserine, L targinine, gamma-glutamyl-gamma-aminobutyraldehyde and pyridoxal 5'-phosphate. These differences highlight that significant alternations occur in the pathways of methane metabolism, arginine and proline metabolism, histidine metabolism, beta-alanine metabolism and vitamin B6 metabolism in RCC compared with LCC. CONCLUSIONS: Identified biomarkers and metabolic pathways may facilate our understanding of the different mortality rates and prognoses between RCC and LCC. PMID- 30296445 TI - Harsh environments: Multi-player cooperation with excludability and congestion. AB - The common-enemy hypothesis of by-product mutualism proposes that organisms are more likely to cooperate when facing the common enemy of a harsher environment. Micro-foundations of this hypothesis have so far focused on the case where cooperation consists of the production of a pure public good. In this case, the effect of a harsher environment is ambiguous: not only a common-enemy effect is possible, but also an opposite, competing effect where the harsher environment reduces the probability of cooperation. This paper shows that unambiguous effects of a harsher environment are predicted when considering the realistic case where the collective good produced is excludable (in the sense that whether or not a player benefits from the collective good depends on whether or not he is contributing) and/or congestible (in the sense that the benefits the individual player obtains from the collective good are affected by the number of contributing players). In particular, the competing effect is systematically predicted for club goods, where defectors are excluded from the benefits of the collective good. A common-enemy effect is instead systematically predicted for charity goods, where cooperators are excluded from the benefits of the collective good. These effects are maintained for congestible club goods and for congestible charity goods. As the degree to which a collective good is excludable can be meaningfully compared across different instances of cooperation, these contrasting predictions for public good, charity goods and club goods yield testable hypotheses for the common-enemy hypothesis of by-product mutualism. PMID- 30296446 TI - Building matrix population models when individuals are non-identifiable. AB - Matrix Population Models (MPM) are among the most widely used tools in ecology and evolution. These models consider the life cycle of an individual as composed by states to construct a matrix containing the likelihood of transitions between these states as well as sexual and/or asexual per-capita offspring contributions. When individuals are identifiable one can parametrize an MPM based on survival and fertility data and average development times for every state, but some of this information is absent or incomplete for non-cohort data, or for cohort data when individuals are not identifiable. Here we introduce a simple procedure for the parameterization of an MPM that can be used with cohort data when individuals are non-identifiable; among other aspects our procedure is a novelty in that it does not require information on stage development (or stage residence) times, which current procedures require to be estimated externally, and it is a frequent source of error. We exemplify the procedure with a laboratory cohort dataset from Eratyrus mucronatus (Reduviidae, Triatominae). We also show that even if individuals are identifiable and the duration of each stage is externally estimated with no error, our procedure is simpler to use and yields the same MPM parameter estimates. PMID- 30296447 TI - PBMDR: A particle swarm optimization-based multifactor dimensionality reduction for the detection of multilocus interactions. AB - Studies on multilocus interactions have mainly investigated the associations between genetic variations from the related genes and histopathological tumor characteristics in patients. However, currently, the identification and characterization of susceptibility genes for complex diseases remain a great challenge for geneticists. In this study, a particle swarm optimization (PSO) based multifactor dimensionality reduction (MDR) approach was proposed, denoted by PBMDR. MDR was used to detect multilocus interactions based on the PSO algorithm. A test data set was simulated from the genotype frequencies of 26 SNPs from eight breast-cancer-related gene. In simulated disease models, we demonstrated that PBMDR outperforms existing global optimization algorithms in terms of its ability to explore and power to detect specific SNP-genotype combinations. In addition, the PBMDR algorithm was compared with other algorithms, including PSO and chaotic PSOs, and the results revealed that the PBMDR algorithm yielded higher accuracy and chi-square values than other algorithms did. PMID- 30296448 TI - Mathematical modeling of bone marrow - peripheral blood dynamics in the disease state based on current emerging paradigms, part II. AB - The cancer stem cell hypothesis has gained currency in recent times but concerns remain about its scientific foundations because of significant gaps that exist between research findings and comprehensive knowledge about cancer stem cells (CSCs). In this light, a mathematical model that considers hematopoietic dynamics in the diseased state of the bone marrow and peripheral blood is proposed and used to address findings about CSCs. The ensuing model, resulting from a modification and refinement of a recent model, develops out of the position that mathematical models of CSC development, that are few at this time, are needed to provide insightful underpinnings for biomedical findings about CSCs as the CSC idea gains traction. Accordingly, the mathematical challenges brought on by the model that mirror general challenges in dealing with nonlinear phenomena are discussed and placed in context. The proposed model describes the logical occurrence of discrete time delays, that by themselves present mathematical challenges, in the evolving cell populations under consideration. Under the challenging circumstances, the steady state properties of the model system of delay differential equations are obtained, analyzed, and the resulting mathematical predictions arising therefrom are interpreted and placed within the framework of findings regarding CSCs. Simulations of the model are carried out by considering various parameter scenarios that reflect different experimental situations involving disease evolution in human hosts. Model analyses and simulations suggest that the emergence of the cancer stem cell population alongside other malignant cells engenders higher dimensions of complexity in the evolution of malignancy in the bone marrow and peripheral blood at the expense of healthy hematopoietic development. The model predicts the evolution of an aberrant environment in which the malignant population particularly in the bone marrow shows tendencies of reaching an uncontrollable equilibrium state. Essentially, the model shows that a structural relationship exists between CSCs and non-stem malignant cells that confers on CSCs the role of temporally enhancing and stimulating the expansion of non-stem malignant cells while also benefitting from increases in their own population and these CSCs may be the main protagonists that drive the ultimate evolution of the uncontrollable equilibrium state of such malignant cells and these may have implications for treatment. PMID- 30296449 TI - The seismic wave motion camouflage of large carnivorous dinosaurs. AB - Living elephants produce seismic waves during vocalizations and locomotion that are potentially detectable at large distances. In the Mesozoic world, seismic waves were probably a very relevant source of information about the behavior of large dinosaurs. In this work, we study the relationship between foot shape and the directivity pattern of seismic waves generated during locomotion. For enlarged foot morphologies (based on a morphological index) of theropod dinosaurs, there is a marked effect of seismic wave directivity at 20 m. This effect is not important in the foot morphologies of other dinosaurs, including the foot shapes of herbivores and theropods such as therizinosaurids. This directivity produces a lower intensity in the forward direction that would slightly reduce the probability of detection of an ambush predator. Even more relevant is the fact that during the approach of a predator, the intensity of seismic waves detected by potential prey remains constant in the mentioned distance range. This effect hides the predator's approach, and we call this "seismic wave camouflage". We also discuss the potential relationship of this effect with enlarged fossil footprints assigned to metatarsal support. PMID- 30296450 TI - Thresholds in the resilience of modular social networks to invasion by defectors. AB - Cooperative interactions constitute the backbone of many biological and social systems. Since cooperation is prone to exploitation, these systems must incorporate mechanisms that prevent the spreading of defective behaviors. One such mechanism is modularity, i.e., the tendency of a social network to be organized in modules, where individuals within a module tend to interact strongly among themselves while avoiding interacting with individuals from other modules. This structure allows cooperation to prevail by having modules of cooperative individuals with a limited exposure to defectors. To address the rate and shape of the effect of modularity on the resilience of cooperation, here we study a variant of the Prisoner's Dilemma on modular networks. Our simulations reveal a sharp transition between a resilient and a vulnerable regime as modularity exceeds a critical threshold. By using a simplified mathematical model, we show that the observed threshold is equivalent to the epidemic threshold found in a certain class of SIR models. This allows us to derive an explicit condition under which a cooperative society is expected to be resilient to invasive defectors. PMID- 30296451 TI - Nutritional supplementation in the treatment of glaucoma: a systematic review. AB - Current treatment strategies for glaucoma are limited to halting disease progression and do not restore lost visual function. Intraocular pressure (IOP) is the main risk factor for glaucoma and IOP-lowering treatment remains the mainstay of glaucoma treatment, but even successful IOP reduction does not stop the progression of glaucoma in all patients. We review the literature to determine whether nutritional interventions intended to prevent or delay the progression of glaucoma can prove to be a valuable addition to the mainstay of glaucoma therapy. A total of 33 intervention trials were included in this review, including 21 randomized controlled trials. These suggest that flavonoids exert a beneficial effect in glaucoma, particularly in terms of improving ocular blood flow and potentially slowing progression of visual field loss. Additionally, supplements containing forskolin have consistently demonstrated the capacity to significantly reduce IOP beyond the levels achieved with traditional therapy alone; however, despite the strong theoretical rationale and initial clinical evidence for the beneficial effect of dietary supplementation as an adjunct therapy for glaucoma, the evidence is not conclusive. More and better quality research is required to evaluate the role of nutritional supplementation in glaucoma. PMID- 30296452 TI - Conserved epitopes in variants of amastin protein of Trypanosoma cruzi for vaccine design: A bioinformatics approach. AB - Chagas disease caused by protozoan parasite Trypanosoma cruzi is endemic disease in South and Central American countries but due to migrating human populations it has shown emergence in Europe, North America and Australia. With only two drugs, benznidazole and nifurtimox for its treatment there is need for newer therapies. In the current study, we have tried to analyse the potential of amastin, a major surface protein as a vaccine target using bioinformatics tools. Using 282 variants of this protein available in NCBI protein database we have found out five conserved potential Tc cell and two TH cell epitopes. These epitopes are conserved in more than 90% of the cohort of sequences used in the study. The epitopes showed binding to the peptide binding cleft of HLA-A02 and HLA-DR molecules. With coverage of pan world populations and being non-toxic and non allergic these epitopes could be used for future vaccine applications. PMID- 30296453 TI - Effects of resistance training on neuromuscular parameters in elderly with type 2 diabetes mellitus: A randomized clinical trial. AB - This study is a randomized controlled clinical trial that verified the resistance training efficacy on neuromuscular parameters, with muscle quality as primary outcome. Forty-four elderly with diabetes type 2 (69.7 +/- 6.9 years; 26 men) were randomly allocated to a 12-weeks resistance training group (RTG, 3 times a week), or an active control group with stretching classes (CG, once a week). Primary and secondary outcomes were assessed at baseline and after 12 weeks, as follow: quadriceps muscle thickness and rectus femoris muscle quality, maximal knee extension strength, rapid strength, functional performance, visceral adipose tissue, glycemic control, lipid profile and quality of life. Generalized estimating equations were used to analyses based on intention-to-treat and per protocol approaches, which showed the same results. Among all outcomes measured there were improvements in the knee extension strength (P < 0.001) and quadriceps muscle thickness (P < 0.001) for RTG. The muscle quality did not improve for both groups (P = 0.98). For the secondary outcomes there were no improvements for functional performance, rapid strength, glycemic control, quality of life, visceral adipose tissue and lipid profile in both groups, with exception of triglyceride level reduction for RTG (P = 0.04).The resistance training program is an efficacious strategy for improve the neuromuscular health in elderly with T2DM, considering increases in lower limb strength and muscle mass, but the same was not found for muscle quality, rapid strength, functional performance and quality of life. Furthermore, the training program did not induce significant reduction in glycated hemoglobin values of patients who already had suitable glycemic control. PMID- 30296454 TI - Associations between gait coordination, variability and motor cortex inhibition in young and older adults. AB - Interlimb coordination and gait performance diminish with age, posing a risk for gait-related injuries. Further, levels of inhibition within the motor cortex are significantly associated with coordination of the upper extremities in healthy aging, however, it is unknown if this same association exists for lower extremity control. To investigate the relationship between gait coordination and cortical inhibition we measured gait coordination via the phase coordination index and motor cortex inhibition via the cortical silent period in 14 young and 15 older adults. Gait coordination was reduced in older adults while walking at their self selected pace, as was cortical inhibition, solely in the non-dominant motor cortex. Furthermore, young adults were better able to maintain lower extremity coordination and variability with reduced cortical inhibition, whereas older adults with increased cortical inhibition demonstrated better walking performance. These findings suggest a fundamental shift in the relationship between motor cortex inhibition and lower extremity control with age, similar to previous work demonstrating an age-related difference in the association between motor cortex inhibition with bimanual control. PMID- 30296455 TI - Cunaniol-elicited seizures: Behavior characterization and electroencephalographic analyses. AB - This study aimed at describing the characteristics and properties of seizures induced by cunaniol, a polyacetylenic alcohol isolated from the Clibadium genus, which is ubiquitous in the Amazon biodiversity and its potential use as a convulsant model. Wistar rat behavior was assessed upon cunaniol administration and animals were evaluated for neural activity through electroencephalographic records whereby epidural electrodes were positioned over the motor cortex under cunaniol-elicited seizures and seizure's control using three anticonvulsant agents, namely phenytoin, phenobarbital and diazepam. Cunaniol-induced seizures displayed a cyclic development of electrocorticographic seizures, presenting interictal-like spike and ictal period, which correlates to the behavioral observations and is in line with acute seizures induced by pentylenetetrazole. Cunaniol-elicited seizures were intractable by phenytoin treatment and controlled under the GABAergic activities of phenobarbital and diazepam. The results indicate that the cunaniol-induced changes show characteristics of seizure activity, making this plant compound a suitable animal convulsant model for seizure-related studies that could be used to assist in the development of novel anticonvulsant agents. PMID- 30296456 TI - Metabolic dynamics of human Sertoli cells are differentially modulated by physiological and pharmacological concentrations of GLP-1. AB - Obesity incidence has pandemic proportions and is expected to increase even further. Glucagon-like peptide-1 (GLP-1) based therapies are well-established pharmacological resources for obesity treatment. GLP-1 regulates energy and glucose homeostasis, which are also crucial for spermatogenesis. Herein, we studied the GLP-1 effects in human Sertoli cells (hSCs) metabolism and mitochondrial function. hSCs were cultured in absence or exposed to increasing doses of GLP-1 mimicking physiological post-prandial (0.01 nM) levels or equivalent to pharmacological levels (1 and 100 nM) used for obesity treatment. We identified GLP-1 receptor in hSCs. Consumption/production of extracellular metabolites were assessed, as well as protein levels or activities of glycolysis related enzymes and transporters. Mitochondrial membrane potential and oxidative damage were evaluated. Glucose consumption decreased, while lactate production increased in hSCs exposed to 0.01 and 1 nM GLP-1. Though lactate dehydrogenase (LDH) protein decreased after exposure to 100 nM GLP-1 its activity increased in hSCs exposed to the same concentration of GLP-1. Mitochondrial membrane potential decreased in hSCs exposed to 100 nM of GLP-1, while formation of carbonyl groups was decreased in those cells. Those effects were followed by an increase in p mammalian target of rapamycin (mTOR) Ser(2448). Overall, the lowest concentrations of GLP-1 increased the efficiency of glucose conversion to lactate, while GLP-1 concentration of 100 nM induces mTOR phosphorylation, decreases mitochondrial membrane potential and oxidative damage. GLP-1 regulates testicular energy homeostasis and pharmacological use of GLP-1 analogues could be valuable to counteract the negative impact of obesity in male reproductive function. PMID- 30296457 TI - Primary resistance mechanism of the canine distemper virus fusion protein against a small-molecule membrane fusion inhibitor. AB - Morbilliviruses (e.g. measles virus [MeV] or canine distemper virus [CDV]) employ the attachment (H) and fusion (F) envelope glycoproteins for cell entry. H protein engagement to a cognate receptor eventually leads to F-triggering. Upon activation, F proteins transit from a prefusion to a postfusion conformation; a refolding process that is associated with membrane merging. Small-molecule morbilliviral fusion inhibitors such as the compound 3G (a chemical analog in the AS-48 class) were previously generated and mechanistic studies revealed a stabilizing effect on morbilliviral prefusion F trimers. Here, we aimed at designing 3G-resistant CDV F mutants by introducing single cysteine residues at hydrophobic core positions of the helical stalk region. Covalently-linked F dimers were generated, which highlighted substantial conformational flexibility within the stalk to achieve those irregular F conformations. Our findings demonstrate that "top-stalk" CDV F cysteine mutants (F-V571C and F-L575C) remained functional and gained resistance to 3G. Conversely, although not all "bottom-stalk" F cysteine variants preserved proper bioactivity, those that remained functional exhibited 3G-sensitivity. According to the recently determined prefusion MeV F trimer/AS-48 co-crystal structure, CDV residues F-V571 and F-L575 may directly interact with 3G. A combination of conformation-specific anti-F antibodies and low-resolution electron microscopy structural analyses confirmed that 3G lost its stabilizing effect on "top-stalk" F cysteine mutants thus suggesting a primary resistance mechanism. Overall, our data suggest that the fusion inhibitor 3G stabilizes prefusion CDV F trimers by docking at the top of the stalk domain. PMID- 30296458 TI - Identification and full-genome characterization of novel circoviruses in masked palm civets (Paguma larvata). AB - The family Circoviridae comprises a large group of small, circular, single stranded DNA viruses and is classified into two genera: Circovirus and Cyclovirus. They have marked genetic diversity and a broad host range. In this study, three novel circovirus genomes were identified from wild-caught masked palm civets (Paguma larvata) in Japan and classified as a new species within the genus Circovirus based on the demarcation criteria of the International Committee on the Taxonomy of Viruses. Of note, the presence of two predicted introns at the 5'-terminus of the rep gene was suggested in the Paguma larvata circovirus genomes. PMID- 30296459 TI - Na+, K+-ATPase inhibition causes hyperactivity and impulsivity in mice via dopamine D2 receptor-mediated mechanism. AB - Hyperactivity and impulsivity are common symptoms in several psychiatric disorders. Although dysfunction of Na+, K+-ATPase has been reported to be associated with the psychiatric disorders, it is not clear whether inhibition of Na+, K+-ATPase causes behavioral effects, including hyperactivity and impulsivity, in mice. Here, we evaluated the effect of intracerebroventricular (icv) injection of ouabain, an inhibitor of Na+, K+-ATPase, on hyperactivity and impulsivity in mice. At seven days after icv injection, ouabain-injected mice displayed the increase in the distance traveled in the open field arena in the open field test and the increase in the number of head-dipping behavior in the cliff avoidance test. Chlorpromazine or haloperidol, typical antipsychotics, reduced the hyperactivity and impulsivity in ouabain-injected mice. On the other hand, neither lithium carbonate nor valproate, established mood-stabilizing drugs, improved hyperactivity and impulsivity in our mouse model. Furthermore, ouabain-injected mice exhibited the increase in the number of c-fos-positive cells in the nucleus accumbens and the prefrontal cortex but not in the ventral tegmental area, which was reduced by haloperidol. These results suggest that the dysfunction of Na+, K+-ATPase causes hyperactivity and impulsivity via hyperactivation of dopamine D2 receptor-mediated signaling pathway, causing disturbed neuronal circuits in mice. PMID- 30296460 TI - AIEgen based drug delivery systems for cancer therapy. AB - Fluorescent drug delivery systems provide a means to track drug release, trace processes of translocation, monitor excretion of anticancer agents and predict therapeutic responses. Traditional fluorescent dye-labeled drug delivery systems often suffer from notorious aggregation-caused quenching (ACQ) with greatly impeded imaging performance. The emerging fluorogens with aggregation-induced emission characteristics (AIEgens) have provided an elegant alternative to tackle this challenge. Recently, fluorescent drug delivery systems based on AIEgens which combine fluorescence imaging and drug delivery have been extensively studied for the development of theranostic nanomedicine. In this review, we summarize the recent development of fluorescent drug delivery systems using AIEgens as the signal reporter. This review is organized according to the drug delivery systems, which include: (1) AIEgens as the drug delivery carrier; (2) AIE polymer as the drug delivery carrier; (3) Organic-inorganic AIE nanocarrier for drug delivery; (4) Supramolecular AIE system for drug delivery. Through illustration of their design principles and application examples, we hope to stimulate more interest in the design of more advanced fluorescent drug delivery systems based on AIEgens for cancer therapy.

METHODS: Data from a prospective cohort, the Australian Longitudinal Study on Women's Health, were used. Nulliparous women aged 18-23 who reported a pregnancy up to age 37-42 were included. Preconception predictors of GDM during a first pregnancy were selected using logistic regression. Regression coefficients were multiplied by a shrinkage factor estimated with bootstrapping to improve prediction in external populations. RESULTS: Among 6504 women, 314 (4.8%) developed GDM during their first pregnancy. The final prediction model included age at menarche, proposed age at future first pregnancy, ethnicity, body mass index, diet, physical activity, polycystic ovary syndrome, and family histories of type 1 or 2 diabetes and GDM. The model showed good discriminative ability with a C-statistic of 0.79 (95% CI 0.76, 0.83) after internal validation. More than half of the women (58%) were classified to be at risk of GDM (>2% predicted risk), with corresponding sensitivity and specificity values of 91% and 43%. CONCLUSIONS: Nulliparous women at risk of GDM in a future first pregnancy can be accurately identified based on preconception lifestyle and health-related characteristics. Further studies are needed to test our model in other populations. PMID- 30296463 TI - Bacopa monnieri alleviates paraquat induced toxicity in Drosophila by inhibiting jnk mediated apoptosis through improved mitochondrial function and redox stabilization. AB - Paraquat (PQ) is an organic chemical compound and a member of redox active family of heterocycles. In spite of its high toxicities, it is used as one of the potent herbicide throughout the world. Though its toxic manifestations are observed in different organs, its principal toxic effect is manifested in the brain leading to the development of Parkinsonian symptoms. PQ exposure adversely affects dopaminergic (DA-ergic) neuron-rich region in the substantia nigra pars compacta (SNPC) of brain in the animal models of Parkinson's disease (PD), thereby mimicking PD like symptoms. Currently, lack of a potential drug to counter the toxic effect of PQ makes the management difficult. Bacopa monnieri extract (BME) has been shown to have promising effect against neurodegenerative disorders. Therefore, the present study evaluated the role of BME against PQ induced toxicity in Drosophila model of PD, the results of which are reproducible in higher animal models including human subjects. Here, we showed that BME treatment attenuates acute PQ induced toxicity in Drosophila by decreasing mortality and improving climbing ability. BME functions by optimizing redox equilibrium, mitochondrial function and depreciating apoptosis level. The underlying mechanisms were attributed to optimization of active JNK and cleaved Caspase-3 activity along with transcriptional stabilization of the genes regulating oxidative stress and apoptosis (jnk, caspase-3, damb and nrf-2). These results showed therapeutic efficacy of BME against PQ toxicity in the brain. Our results pave the way for further detailed analysis of BME to combat the development of Parkinson's like symptoms following exposure to PQ toxicity in the brain of higher animal models. PMID- 30296461 TI - Reducing inflammation through delivery of lentivirus encoding for anti inflammatory cytokines attenuates neuropathic pain after spinal cord injury. AB - Recently, many clinical trials have challenged the efficacy of current therapeutics for neuropathic pain after spinal cord injury (SCI) due to their life-threatening side-effects including addictions. Growing evidence suggests that persistent inflammatory responses after primary SCI lead to an imbalance between anti-inflammation and pro-inflammation, resulting in pathogenesis and maintenance of neuropathic pain. Conversely, a variety of data suggest that inflammation contributes to regeneration. Herein, we investigated long-term local immunomodulation using anti-inflammatory cytokine IL-10 or IL-4-encoding lentivirus delivered from multichannel bridges. Multichannel bridges provide guidance for axonal outgrowth and act as delivery vehicles. Anti-inflammatory cytokines were hypothesized to modulate the pro-nociceptive inflammatory niche and promote axonal regeneration, leading to neuropathic pain attenuation. Gene expression analyses demonstrated that IL-10 and IL-4 decreased pro-nociceptive genes expression versus control. Moreover, these factors resulted in an increased number of pro-regenerative macrophages and restoration of normal nociceptors expression pattern. Furthermore, the combination of bridges with anti inflammatory cytokines significantly alleviated both mechanical and thermal hypersensitivity relative to control and promoted axonal regeneration. Collectively, these studies highlight that immunomodulatory strategies target multiple barriers to decrease secondary inflammation and attenuate neuropathic pain after SCI. PMID- 30296464 TI - The complete mitochondrial genome of Budorcas taxicolor tibetana (Artiodactyla: Bovidae) and comparison with other Caprinae species: Insight into the phylogeny of the genus Budorcas. AB - Takin (Budorcas taxicolor) is one of the most endangered species. However, the taxonomy of takin is still in dispute. Here, the complete mitochondrial genome of Budorcas taxicolor tibetana was reported for the first time, which featured a typical circular molecule of 16,665 bp in length, including 13 PCGs, 22 tRNAs, two rRNAs, and one control region. A + T content was higher than G + C content. All of the genes were encoded on the heavy strand, except for eight tRNAs and ND6 gene. The OL region was 49 bp in length and highly conserved in the synthesis and stem-loop regions, and all of the substitutions and indels were found only in the loop structure. Three types of tandem repeat units, six pairs of hairpin loop structure (TACAT, ATGTA) and six CSBs were predicted in the control region. Our results clearly revealed the systematic status of Budorcas species, and the phylogenetic analyses indicated that Budorcas was closer to Capra and Pseudois, rather than to Ovis, which should be merged into the subfamily of Caprinae. PMID- 30296465 TI - MiR-650 regulates the proliferation, migration and invasion of human oral cancer by targeting growth factor independent 1 (Gfi1). AB - Oral cancer being one of the lethal cancers is generally detected at advanced stages and causes significant mortality world over. The unavailability of the reliable biomarkers and therapeutic targets/agents forms a bottleneck in the treatment of oral cancer. MicroRNAs are considered of immense therapeutic potential for the treatment of cancer. Consistently, in this study the role and therapeutic potential of miR-650 was explored in oral cancer. The analysis of miR 650 expression by qRT-PCR revealed significant (p < 0.05) upregulation of miR-650 in oral cancer cell lines. Cell cycle analysis by flow cytometery revealed that suppression of miR-650 significantly (p < 0.05) inhibits the proliferation of the SCC-25 cells by prompting Sub-G1 cell cycle arrest. Further, miR-650 suppression also inhibited the migration and invasion of the SCC-25 oral cancer cells as revealed by transwell assays. TargetScan analysis showed that miR-650 targets Growth factor independent 1 (Gfi1). Moreover, the results of western blot analysis showed that miR-650 suppression inhibits the expression of Gfi1. Interestingly, suppression of Gfi1 exhibited similar effects on cell proliferation, migration and invasion of the oral cancer cells as that of miR-650 suppression. Nonetheless, miR-650 promoted the proliferation, migration and invasion of the SCC-25 cells by upregulating the expression of Gfi1. Moreover, overexpression of miR-650 could not rescue the effects of Gfi1 silencing on SCC 25 oral cancer cells. Conversely, overexpression of Gfi1 could rescue the effects of miR-650 inhibition on SCC-25 cell proliferation, migration and invasion. Additionally, miR-650 suppression could also inhibit the xenografted tumor growth in vivo by inhibiting the expression of Gfi1. Taken together, miR-650 may prove to be an important therapeutic target for the management of oral cancers. PMID- 30296466 TI - A systematic review of in vitro cytokine production in eating disorders. AB - BACKGROUND: Eating disorders (EDs) have been associated with alterations in cytokine concentrations and production. This review examines whether in vitro cytokine production (i) is altered in people with EDs compared to healthy participants; and (ii) changes in response to treatment? METHODS: Using PRISMA guidelines, we systematically reviewed articles reporting group comparisons or longitudinal assessments of spontaneous and/or stimulated cytokine production in vitro in people with EDs. RESULTS: Twelve studies were included. Cross-sectional results were mixed in anorexia nervosa. Only one study measured cytokine production in bulimia nervosa. Two longitudinal studies showed that daily yoghurt consumption increases phytohemagglutinin-stimulated interferon-gamma production in anorexia nervosa. CONCLUSION: The mixed results could be accounted for by variations in experimental design. Our findings suggest that cytokine production could possibly be modulated through dietary interventions. However, due to the methodological heterogeneity and shortcomings of the included studies, it seems unreasonable to draw further conclusions. PMID- 30296467 TI - Neutral is negative enough-Peer victimization influences cardiac, facial-muscular and experiential reactions to both negative evaluative and neutral social stimuli. AB - Physiological stress responses vary as a function of adverse childhood experiences. However, previous studies concentrate on familial sources of childhood adversity. Potential long-term effects of peer victimization on physiology and affective responses are less known. This study examined cardiac, facial-muscular, and experiential responses to social evaluative stimuli in ninety-four healthy subjects with various degrees of experienced peer victimization. In a social conditioning task, peer victimization was associated with similarly attenuated cardiac and facial-muscular responses to negative and neutral stimuli, while differentiated physiological responses to negative and neutral stimuli were found in subjects without peer victimization. Overall, increased ratings of arousal, valence and disapproval for negative compared to neutral stimuli were found. Contrary to the physiological response, peer victimization was associated with more negative ratings of negative stimuli one month after acquisition. The results suggest that the physiological and experiential reactivity towards both negative and neutral social stimuli is affected by the experience of peer victimization. Peer victimization causes generalized autonomic dysregulation and memory recall biases during social learning impeding adequate response preparation to social stressors. PMID- 30296468 TI - Use and handling safety of Mini-Spike 2(r) chemo and puresite for safe chemotherapy compounding in a hospital pharmacy. AB - We wanted to evaluate the impact of Mini-Spike 2(r) Chemo + Puresite (MSCP) use on contamination surface levels, professionals' satisfaction and compounding time at pharmacy compared with PhasealTM. Presence of cyclophosphamide (CYP) and 5 fluorouracil (5FU) was evaluated at three sampling times: baseline; after a decontamination procedure and six months after MSCP use for CYP and 5FU compounding. Testing was carried out using an independent laboratory and wipe testing kit. To test compounding time, four different nurses followed the same compounding protocol with each device. We also developed a questionnaire to obtain feedback from the nurses. We did not find statistically significant differences in the median contamination surface levels between basal and final sampling time, CYP (0.140; 95% CI -1.135, 1.601), 5FU (-0.506; 95% CI -1.756, 0.287). We observed a difference of 10 s on compounding times between the two devices tested (p < 0.001) favoring MSCP. Finally, eight nurses answered the survey, with the best valued aspect as the aspiration/injection flow and resistance, and the worst value the comfort using Puresite and valve connection. MSCP maintains low surface contamination levels in our setting assuring compounding time standards. Satisfaction survey let us know which were the major advantages and disadvantages of the device. PMID- 30296469 TI - Effect of a binge-like dosing regimen of methamphetamine on dopamine levels and tyrosine hydroxylase expressing neurons in the rat brain. AB - Methamphetamine, an amphetamine derivative, is a powerful psychomotor stimulant and commonly used drug of abuse. This study examined the effect of binge-like methamphetamine (MA) dosing (4 * 4 mg/kg, s.c., 2 h apart) on regional dopamine and dopaminergic metabolite levels in rat brain at a range of early time points after final dose (2-48 h). Body temperature was elevated when measured 2 h after the last dose. MA increased dopamine levels in the frontal cortex 2 and 24 h after the last dose. The dopamine level was also increased in the amygdala at 24 h. No change was observed in the striatum at any time point, but levels of the dopamine metabolite DOPAC were markedly reduced at 24 and 48 h. Tyrosine hydroxylase expression is induced downstream of dopamine activity, and it is the rate limiting enzyme in dopamine synthesis. The effect of MA binge-like dosing on the volume of tyrosine hydroxylase containing cell bodies and the area fraction of tyrosine hydroxylase containing fibres was also assessed. MA increased the area fraction of tyrosine hydroxylase fibres in the frontal cortex and reduced the volume of tyrosine hydroxylase containing cell bodies 2 h after last dose in the ventral tegmental area and the substantia nigra. An increase in cell body volume in the substantia nigra was observed 48 h after treatment. These findings collectively highlight the importance of the dopaminergic system in methamphetamine induced effects, identify the frontal cortex, amygdala and striatum as key regions that undergo early changes in response to binge-like methamphetamine dosing and provide evidence of time-dependent effects on the cell bodies and fibres of tyrosine hydroxylase expressing neurons. PMID- 30296470 TI - Protective role of Apelin-13 on amyloid beta25-35-induced memory deficit; Involvement of autophagy and apoptosis process. AB - Alzheimer's disease (AD) by progressive neurodegenerative pattern is associated with autophagy stress which is suggested as a potential cause of amyloid beta (Abeta) aggregation and neural loss. Apelin-13, a neuropeptide with modulatory effect on autophagy, has been shown the beneficial effects on neural cell injuries. We investigated the effect of Apelin-13 on Abeta-induced memory deficit as well as autophagy and apoptosis processes. We performed bilateral intra-CA1 injection of Abeta25-35 alone or in combination with Apelin-13. Spatial reference and working memory was evaluated using the Morris water maze (MWM) and Y-maze tests. Hippocampus was harvested on 2, 5, 10 and 21 days after Abeta injection. The light chain 3 (LC3II/I) ratio, histone deacetylase 6 (HDAC6) level, Caspase-3 cleavage, and mTOR phosphorylation were assessed using western blot technique. Intra-CA1 injection of Abeta caused impairment of working and spatial memory. We observed higher LC3II/I ratio, cleaved caspase-3 and lower HDAC6, and p-mTOR/mTOR ratio in Abeta-treated animals. Apelin-13 provided significant protection against the destructive effects of Abeta on working and spatial memory. Apelin-13 prevented the increase of LC3II/I ratio and cleaved caspase-3 on days 10 and 21 after injection of Abeta. It also limited the Abeta-induced reduction in HDAC6 expression. This implies that Apelin-13 has suppressed both autophagy and apoptosis. Our findings suggested that the neuroprotection of Apelin-13 may be in part related to autophagy and apoptosis inhibition via the mTOR signaling pathway. Apelin-13 may be a promising approach to improve memory impairment and potentially pave the way for new therapeutic plans in AD. PMID- 30296471 TI - A simple and highly efficient method for gene silencing in Escherichia coli. AB - Here we present a simple and rapidly achievable protocol for gene silencing in Escherichia coli (E. coli). In this procedure, antisense RNA (asRNA) of 400 nucleotides (nt) length and absolute complementarity to the target is produced by an expression plasmid. The designed asRNA should ideally cover at least the -10 site of the promoter and the Shine-Dalgarno sequence, and additional 300-bp of the following open reading frame of the target gene. We show that the transcription process of the target is not affected at all, whereas the translation process is impaired. Based on high constitutive expression of asRNA we were able to extend the silencing effect to knock-out levels. By inducible expression, we show that also the modulation is possible. This technique should be widely useful to study gene function in E. coli and other bacteria. PMID- 30296472 TI - Eating As Treatment (EAT): a stepped-wedge, randomised controlled trial of a health behaviour change intervention provided by dietitians to improve nutrition in patients with head and neck cancer undergoing radiotherapy (TROG 12.03). AB - PURPOSE: Malnutrition in head and neck cancer (HNC) treatment is common and associated with poorer morbidity and mortality outcomes. This trial aimed to improve nutritional status during radiotherapy using a novel method of training dietitians to deliver psychological techniques to improve HNC patients' nutritional behaviours. METHODS AND MATERIALS: This trial used a stepped wedge randomised controlled design to assess the efficacy of Eating As Treatment (EAT). Based on Motivational Interviewing and Cognitive Behavioural Therapy, EAT was designed to be delivered by oncology dietitians and integrated into their clinical practice. During control steps, dietitians provided treatment as usual, before being trained in EAT and moving into the intervention phase. The training was principles based and sought to improve behaviour change skills rather than provide specific scripts. Patients recruited (151 controls, 156 intervention) to the trial were assessed at four time points (first and final week of Radiotherapy, four and twelve weeks post). The primary outcome was nutritional status at the end of RT as measured by the Patient Generated Subjective Global Assessment (PG-SGA). RESULTS: Patients who received the EAT intervention had significantly better scores on the primary outcome of nutritional status at the critical end of treatment time point (beta=-1.53 (-2.93 to -.13) p=.03). Intervention patients were also significantly more likely to: be assessed as well nourished at each time point; lose a smaller percentage of weight have fewer treatment interruptions; present lower depression scores; and report a higher quality of life. Although not statistically significant, those who received the intervention had fewer and shorter unplanned hospital admissions. CONCLUSIONS: This trial is the first of its kind to demonstrate the effectiveness of a psychological intervention to improve nutrition in HNC patients receiving radiotherapy. It provides a means to ameliorate malnutrition and the important related outcomes and consequently should be incorporated into standard care for patients receiving HNC radiotherapy. PMID- 30296473 TI - Patterns of care and outcome Radiation-Induced Soft Tissue Sarcomas. AB - More than half of all cancer patients receive radiotherapy. With the increasing number of long-term cancer survivors, there is a growing concern about the risk of radiation induced second malignant neoplasm. Sarcomas represent the most frequent type of cancer than can be induced by radiation exposure. We report the largest series of radiation-induced sarcomas (RIS). We demonstrate that a majority of RIS can be cured, provided they underwent well-planned surgery. PMID- 30296474 TI - Parvalbumin Loss Following Chronic Sub-Anesthetic NMDA Antagonist Treatment is Age-Dependent in the Hippocampus: Implications for Modeling NMDA Hypofunction. AB - A marked decrease in parvalbumin (PV), a calcium-binding protein specific to a subset of GABAergic neurons, is a consistent finding in postmortem schizophrenic brain tissue. This reduction is selective to PV and is regionally specific, occurring primarily in the prefrontal cortex and hippocampus (HPC) of patients. Rodent models of NMDA receptor hypofunction utilizing NMDA antagonist treatments e.g. ketamine (KET) - show schizophrenia-like cognitive and behavioral impairments with parallel changes in PV. While decreased PV is considered a hallmark of neuropathology in schizophrenia, previous work elucidating the effects of KET administration on PV are contradictory, with findings suggesting decreased, increased, or no change in PV expression. Upon close examination of the procedures used across studies, there are two primary inconsistencies, including: (1) the age of animals used; and (2) the timeline of post-treatment tissue collection. To better understand whether these key differences impact observed PV changes, the present study investigated the impact of age and time of sacrifice on chronic KET-induced PV changes in the neocortex and HPC. Our findings suggest an effect of age, but not sacrifice timeline, on PV cell count following 14 days of sub-anesthetic KET treatment. We provide evidence that 1 month-old rats exhibit a significant KET-induced HPC PV decrease, while adult rats show a modest increase in HPC PV following chronic KET. Taken together, we propose that PV is a dynamic marker, and that changes in cell counts - and their interpretation - following NDMA antagonist treatment should be considered in the context of age. PMID- 30296476 TI - Application of Sentinel Lymph Node Technique to Transvaginal Natural Orifices Transluminal Endoscopic Surgery in Endometrial Cancer. AB - STUDY OBJECTIVE: This report outlines our first experience of sentinel lymph node (SLN) mapping in the natural orifices transluminal endoscopic surgery (NOTES) technique, which is the combination of the least invasive surgical approach and the least invasive way of assessing lymph node status. DESIGN: Descriptive study (Canadian Task Force classification III). SETTING: Tertiary referral and educational center. PATIENTS: Four patients with endometrial cancer clinical stage 1. INTERVENTIONS: NOTES with SLN mapping using an indocyanine green-based near-infrared fluorescence imaging technique. MEASUREMENTS AND MAIN RESULTS: The average operative time was 182.75 minutes (standard deviation, 34.5). Mean estimated blood loss was 67.5 mL (standard deviation, 39.4). All patients had surgical staging of International Federation of Gynecology and Obstetrics stage IA (pT1aN0). The overall detection rate and bilateral detection rate were 100% (4/4). All procedures were successfully completed without complication or conversion to conventional laparoscopy. CONCLUSION: In our preliminary experience, SLN mapping in NOTES surgery appears to be feasible and safe. It can be considered as an alternative method to reduce morbidity from radical lymphadenectomy and provide the benefits from the NOTES technique. However, studies in a larger population are necessary. PMID- 30296475 TI - Efficacy of a Fibrin Sealant (Tissucol Duo) for the Preventionof Lymphocele after Laparoscopic Pelvic Lymphadenectomy:A Randomized Controlled Trial. AB - STUDY OBJECTIVE: To assess the efficacy of Tissucol Duo (Baxter AG, Vienna, Austria) fibrin sealant in decreasing the incidence of lymphocele (LC) after pelvic laparoscopic lymph node dissection using harmonic shears. DESIGN: Randomized controlled trial (Canadian Task Force classification level I). SETTING: Tertiary referral and educational center. PATIENTS: Seventy-four patients randomized to the use of sealant per hemipelvis. INTERVENTION: Fibrin sealant. MEASUREMENTS AND MAIN RESULTS: After bilateral pelvic lymphadenectomy a fibrin sealant was used in 1 hemipelvis but not the other, applied in 41 patients (55.4%) to the left and 33 patients (44.6%) to the right hemipelvis. The primary outcome was the incidence of LC after surgery in symptomatic and asymptomatic patients. Imaging (ultrasound, computed tomography, and magnetic resonance) was performed to detect LC at 3, 6, and 12 months after surgery. Overall, 26 patients (35.1%) developed LC, and 4 were symptomatic (5.4%). Allowing patients to serve as their own treatment group and control, the hemipelvis treated with Tissucol Duo corresponding to the treatment group and that not treated to the control group, LCs were found in 17 (23%) and 14 (19%) cases, respectively, but the difference was not significant. The mean initial LC maximum diameter was 27.1 mm (standard deviaiotn, 35.2), and LCs tended to decrease in size during the first year to a mean of 8.7 mm. CONCLUSION: Application of Tissucol Duo fibrin sealant after laparoscopic pelvic lymphadenectomy using ultrasonic shears does not decrease the occurrence of symptomatic or asymptomatic LC. PMID- 30296477 TI - Role of calcium in adult onset polycystic kidney disease. AB - Autosomal dominant polycystic kidney disease (ADPKD) is caused by mutations in genes encoding the polycystin (PC) 1 and 2 proteins. The goal of this study was to determine the role of calcium in regulating cyst growth. Stromal interaction molecule 1 (STIM1) protein expression was 15-fold higher in PC1-null proximal tubule cells (PN) than in heterozygote (PH) controls and 2-fold higher in an inducible, PC1 knockout, mouse model of ADPKD compared to a non-cystic match control. IP3 receptor protein expression was also higher in the cystic mice. Knocking down STIM1 with siRNA reduced cyst growth and lowered cAMP levels in PN cells. Fura2 measurements of intracellular Ca2+ showed higher levels of intracellular Ca2+, SOCE and thaspigargin-stimulated ER Ca2+ release in PN vs. PH cells. There was a dramatic reduction in thapsigargin-stimulated release of ER Ca2+ following STIM1 silencing or application of 2-APB, consistent with altered ER Ca2+ movement; the protein expression of the Ca2+-dependent adenylyl cyclases (AC) AC3 and AC6 was up- and down-regulated, respectively. Like STIM1 knockdown, application of the calmodulin inhibitor W7 lowered cAMP levels, further indicating that STIM1 regulates AC3 via Ca2+ We conclude that the high levels of STIM1 in ADPKD cells play a role in supporting cyst growth and promoting high cAMP levels and an increased release of Ca2+ from the ER. Thus, our results provide novel therapeutic targets for treating ADPKD. PMID- 30296478 TI - To treat or not to treat: The minimally symptomatic EoE patient. PMID- 30296480 TI - RNA interference against the putative insulin receptor substrate gene chico affects metamorphosis in Leptinotarsa decemlineata. AB - It is noted that insect insulin/insulin-like growth factor/target of rapamycin signaling is critical for the regulation of metamorphosis in holometabolous insects. However, the molecular mechanism remains undetermined. Our previous findings reveal that RNA interference (RNAi)-mediated knockdown of an insulin gene (LdILP2) in Leptinotarsa decemlineata disturbs both 20-hydroxyecdysone (20E) and juvenile hormone (JH) signaling, and impairs pupation. In the present paper, we further observed that the expression of the insulin receptor substrate gene chico (Ldchico) and the phosphoinositide-3-kinase gene pi3k (Ldpi3k92E) was repressed in LdILP2 depleted larvae. Moreover, RNAi of Ldchico or Ldpi3k92E decreased food consumption, affected absorption and metabolism of amino acids and sugars, and reduced expression of several 20E (LdEcR, LdHR3 and LdE75) and JH (LdJHAMT, LdKr-h1 and LdHairy) signaling genes. As a result, larval development was postponed and larval growth was inhibited. Intriguingly, knockdown of Ldchico, rather than Ldpi3k92E, impaired larval-pupal and pupal-adult ecdysis, and specifically repressed transcription of another 20E signaling gene LdUSP. Ingestion of 20E rescued the expression of LdEcR, LdHR3 and LdE75, whereas 20E feeding restored neither the decreased LdUSP mRNA level, nor the reduced pupation and adult emergence rates in Ldchico RNAi larvae. Therefore, Chico is critical for the regulation of larval-pupal-adult transition by a PI3K-independent pathway, perhaps through activation of USP in L. decemlineata. PMID- 30296479 TI - Employment, Insurance, and Financial Experiences of Patients with Chronic Graft versus-Host Disease in North America. AB - Understanding the socioeconomic impact of chronic graft-versus-host disease (GVHD) on affected patients is essential to help improve their overall well being. Using data from the Chronic GVHD Consortium, we describe the insurance, employment, and financial challenges faced by these patients and the factors associated with the ability to work/attend school and associated financial burdens. A 15-item cross-sectional questionnaire designed to measure financial concerns, income, employment, and insurance was completed by 190 patients (response rate, 68%; 10 centers) enrolled on a multicenter Chronic GVHD Consortium Response Measures Validation Study. Multivariable logistic regression models examined the factors associated with financial burden and ability to work/attend school. The median age of respondents was 56 years, and 87% of the patients were white. A higher proportion of nonrespondents had lower income before hematopoietic cell transplantation and less than a college degree. All but 1 patient had insurance, 34% had faced delayed/denied insurance coverage for chronic GVHD treatments, and 66% reported a financial burden. Patients with a financial burden had greater depression/anxiety and difficulty sleeping. Nonwhite race, lower mental functioning, and lower activity score were associated with a greater likelihood of financial burden. Younger age, early risk disease, and higher mental functioning were associated with a greater likelihood of being able to work/attend school. In this multicenter cohort of patients with chronic GVHD, significant negative effects on finances were observed even with health insurance coverage. Future research should investigate potential interventions to provide optimal and affordable care to at-risk patients and prevent long-term adverse financial outcomes in this vulnerable group. PMID- 30296481 TI - Expression profiling and functional characterization of galectin-3 of turbot (Scophthalmus maximus L.) in host mucosal immunity. AB - Galectins, a family of evolutionary conserved beta-galactoside-binding proteins, have been characterized in a wide range of species. Galectin-3 is the only member in the chimera type, which is a monomeric lectin with one CRD domain. A growing body of evidence have indicated vital roles of galectin-3 in innate immune responses against infection. Here, one galectin-3 gene was captured in turbot (SmLgals3) with a 1203 bp open reading frame (ORF). In comparison to other species, SmLgals3 showed the highest similarity and identity to large yellow croaker and medaka, respectively. The genomic structure analysis showed that SmLgals3 had 5 exons similar to other vertebrate species. The syntenic analysis revealed that galectin-3 had the same neighboring genes across all the selected species, which suggested the synteny encompassing galectin-3 region during vertebrate evolution. Subsequently, SmLgals3 was widely expressed in all the examined tissues, with the highest expression level in brain and the lowest expression level in skin. In addition, SmLgals3 was significantly down-regulated in intestine following both Gram-negative bacteria Vibrio anguillarum, and Gram positive bacteria Streptococcus iniae immersion challenge. Finally, the rSmLgals3 showed strong binding ability to all the examined microbial ligands. Taken together, our results suggested SmLgals3 played vital roles in fish innate immune responses against infection. However, the knowledge of SmLgals3 are still limited in teleost species, further studies should be carried out to better characterize its detailed roles in teleost mucosal immunity. PMID- 30296482 TI - Influenza vaccination coverage among US-Mexico land border crossers: 2009 H1N1 pandemic and 2011-2012 influenza season. AB - BACKGROUND: The high volume of US-Mexico land border crossings can facilitate international dissemination of influenza viruses. METHODS: We surveyed adult pedestrians crossing into the United States at two international land ports of entry to assess vaccination coverage during the 2009H1N1 influenza pandemic and 2011-2012 influenza season. RESULTS: Of 559 participants in 2010, 23.4% reported receipt of the 2009H1N1 vaccine. Of 1423 participants in 2012, 33.7% received the 2011-2012 influenza vaccine. Both years, those crossing the border >=8 times per month had lower vaccination coverage than those crossing less frequently. US border residents had lower H1N1 coverage than those in other locations. Vaccination coverage was higher for persons age >=65 years and, in 2010 only, those with less than high school education. Although most participants believed it is important to get vaccinated, only half believed the influenza vaccine was safe and effective. The main reasons for not receiving the influenza vaccine were beliefs of low risk of disease, time constraints, and concerns about vaccine safety (in 2010) or efficacy (in 2012). CONCLUSIONS: International land border crossers are a large and unique category of travelers that require targeted binational strategies for influenza vaccination and education. PMID- 30296483 TI - Factors associated with severity of tick-borne encephalitis: A prospective observational study. AB - BACKGROUND: Information on parameters associated with the severity of tick-borne encephalitis (TBE) is limited. METHODS: The association between 15 pre-defined parameters and the severity of TBE was evaluated in 717 consecutive adult patients diagnosed in Slovenia 2007-2012. RESULTS: Multivariable logistic regression showed that patient age (odds ratio, OR 1.26, 95% CI 1.11-1.44; P = 0.001), previous vaccination against TBE (OR 14.23, 95% CI 1.72-117.87; P = 0.014), blood leukocyte count (OR 1.45, 95% CI 1.13-1.85; P = 0.004), and level of specific TBE virus serum IgG antibodies (OR 0.85, 95% CI 0.75-0.96; P = 0.009) were associated with severe acute illness based on the clinical diagnosis. When severity of TBE was based on the severity score and linear regression was used, corresponding association was found for age (estimated coefficient, EC 1.70, 95% CI 1.06-2.33; P<0.001), previous vaccination against TBE (EC 11.16, 95% CI 5.05 17.27; P < 0.001), serum C-reactive protein level (EC 1.20, 95% CI 0.48-1.91; P = 0.001), and level of specific TBE virus serum IgG antibodies (EC -0.74, 95% CI 1.27-0.20; P = 0.007). CONCLUSIONS: Previous vaccination against TBE, low levels of TBE virus serum IgG antibodies, older age, higher blood leukocyte count, and higher serum C-reactive protein levels are associated with more severe TBE. PMID- 30296484 TI - Smoking cessation strategies in pregnancy: Current concepts and controversies. AB - Smoking during pregnancy is a risk factor associated with adverse pregnancy outcomes. Despite the fact that these outcomes are well known, a considerable proportion of pregnant women continue to smoke during this critical period. This paper evaluates critically smoking cessation interventions targeting pregnant women. We describe the findings of key published studies, review papers and expert statements to report the efficacy and safety of strategies for smoking cessation in pregnancy, including counselling and pharmacotherapy. Counselling appears to improve quit rates but mainly when used in combination with pharmacological therapy. Pharmacotherapy is recommended for women who are heavy smokers and are unable to quit smoking on their own. Nicotine replacement therapy is a reasonable first-line drug option. It is recommended that women who are pregnant, or planning to become pregnant, should be informed of potential risks for the foetus before considering smoking cessation therapy with bupropion or varenicline. Pregnant women view electronic nicotine delivery systems as being safer than combustible cigarettes, and this indeed may be the case; however, further evidence is required to assess their effectiveness as a smoking cessation aid and their safety for the mother and the child. Postpartum relapse is a significant problem, with approximately one out of two quitters relapsing in the first 2 months after delivery. These women should be considered 'at risk' and provided with ongoing support. PMID- 30296485 TI - Critical Appraisal of Programmed Death Ligand 1 Reflex Diagnostic Testing: Current Standards and Future Opportunities. AB - INTRODUCTION: Patient suitability to anti-programmed death ligand 1 (PD-L1) immune checkpoint inhibition is key to the treatment of NSCLC. We present, applied to PD-L1 testing: a comprehensive cross-validation of two immunohistochemistry (IHC) clones; our descriptive experience in diagnostic reflex testing; the concordance of IHC to in situ RNA (RNA-ISH); and application of digital pathology. METHODS: Eight hundred thirteen NSCLC tumor samples collected from 564 diagnostic samples were analyzed prospectively, and 249 diagnostic samples analyzed retrospectively in tissue microarray format. Validated methods for IHC and RNA-ISH were tested in tissue microarrays and full sections and the QuPath system were used for digital pathology analysis. RESULTS: Antibody concordance of clones SP263 and 22C3 validation was 97% to 98% in squamous cell carcinoma and adenocarcinomas, respectively. Clinical NSCLC cases were reported as PD-L1-negative (48%), 1% to 49% (23%), and more than 50% (29%), with differences associated to tissue-type and EGFR status. Comparison of IHC and RNA-ISH was highly concordant in both subgroups. Comparison of digital assessment versus manual assessment was highly concordant. Discrepancies were mostly around the 1% clinical threshold. Challenging IHC interpretation included 1) calculating the total tumor cell denominator and the nature of PD-L1 expressing cell aggregates in cytology samples; 2) peritumoral expression of positive immune cells; 3) calculation of positive tumor percentages around clinical thresholds; and 4) relevance of the 100 malignant cell rule. CONCLUSIONS: Sample type and EGFR status dictate differences in the expected percentage of PD-L1 expression. Analysis of PD-L1 is challenging, and interpretative guidelines are discussed. PD L1 evaluations by RNA-ISH and digital pathology appear reliable, particularly in adenocarcinomas. PMID- 30296486 TI - Detection of Minimal Residual Disease Using ctDNA in Lung Cancer: Current Evidence and Future Directions. AB - Advances in DNA sequencing methods have significantly expanded the potential clinical applications of analyzing circulating tumor DNA (ctDNA). This genetic information can identify the presence of targetable mutations and has been explored for cancer screening purposes. ctDNA can be obtained without the risks inherent to biopsy, allowing for serial assessments over time. Several studies have additionally suggested that ctDNA can be used to detect the presence of minimal residual disease (MRD) after surgical resection in several cancer types, including lung cancer. The ability to detect MRD would allow clinicians to tailor adjuvant therapies, which carry risks of significant toxicities and may benefit only select groups of patients. Here, we review the current state of ctDNA profiling methods and evaluate the evidence supporting the use of ctDNA analysis to assess for MRD. We discuss how MRD detection could help identify patients at increased risk of disease recurrence and thus guide treatment decisions for resectable lung cancer. Finally, we propose future steps to validate such approaches and expand the utility of these rapidly progressing technologies.

AB - Docosahexaenoic acid (DHA) is one omega-3 fatty acid that is essential for the development and function of the brain. However, a large number of clinical trials found that the DHA supplementation showed no advantage on mental and motor skill development in term infants. A strategy based on DHA nanoencapsulation (nano FO) using an edible plant protein, zein, mimicking the milk structure is applied for enhanced maternal and fetal absorptions of DHA to improve early brain development. The nano FO achieved increased absorption in GI tract, enhanced delivery to the maternal, fetal, and offspring brains, and reduced fatty acid accumulation in the fetal liver. In the behavior assessments, the nano FO diet showed enhanced learning and memory improvement compared to the normal FO diet. It indicated that zein nanoencapsulation is with high potential for drug and nutrient deliveries to brain and through placenta to fetus with no toxicity concern. PMID- 30296489 TI - Isolevuglandins and cardiovascular disease. AB - Isolevuglandins are 4-ketoaldehydes formed by peroxidation of arachidonic acid. Isolevuglandins react rapidly with primary amines including the lysyl residues of proteins to form irreversible covalent modifications. This review highlights evidence for the potential role of isolevuglandin modification in the disease processes, especially atherosclerosis, and some of the tools including small molecule dicarbonyl scavengers utilized to assess their contributions to disease. PMID- 30296488 TI - The immune-metabolic regulatory roles of epoxyeicosatrienoic acids on macrophages phenotypic plasticity in obesity-related insulin resistance. AB - Macrophages in adipose tissue are associated with obesity-induced low-grade inflammation, which contributed to insulin resistance and the related metabolic diseases. Macrophages display phenotypic plasticity, and polarize under the condition of obesity. Epoxyeicosatrienoic Acids (EETs) are lipid mediators that are involved in the regulation of inflammatory cascades and glucose homeostasis. In this mini-review, we briefly summarize the macrophages recruitment, infiltration and polarization in obese mice, and also discuss the immune metabolic regulatory role of EETs in this process (See Fig. 1). PMID- 30296490 TI - Eicosanoids via CYP450 and cardiovascular disease: Hints from genetic and nutrition studies. AB - Metabolites of arachidonic acid via CYP450 such as epoxyeicosatrienoic acids (EETs) and 20-hydroxyeicosatetraenoic acid (20-HETE), have vasoactive and natriuretic properties and have been implicated in BP homeostasis and the incidence of cardio- and cerebrovascular diseases in animal studies. In humans, genetic studies considering genes implicated in arachidonic acids metabolism (CYP4F2, CYP4A11, CYP2J2, CYP2C8, CYP2C9, CYP2A1/2, EPHX2) can offer a hint to understand their role, if any, in hypertension development and its deleterious cardiovascular effects. Candidate genes studies and successive meta-analyses have shown that specific single nucleotide polymorphisms (SNPs), often functional, and haplotypes in these genes were associated with one or more cardiovascular endpoints. Nevertheless, genome wide association studies (GWAS) have never detected any SNPs nearby these genes (the only exception being the CYP2A1/2 locus) as associated with either BP, hypertension, coronary artery disease or stroke questioning their real importance for cardiovascular health in humans. Nutrition studies exploring the effects of specific foods on the formation of these compounds or others through the same pathway can offer new insights on this field. PMID- 30296491 TI - relSCAN - A system for extracting chemical-induced disease relation from biomedical literature. AB - This paper proposes an effective and robust approach for Chemical-Induced Disease (CID) relation extraction from PubMed articles. The study was performed on the Chemical Disease Relation (CDR) task of BioCreative V track-3 corpus. The proposed system, named relSCAN, is an efficient CID relation extraction system with two phases to classify relation instances from the Co-occurrence and Non-Co occurrence mention levels. We describe the case of chemical and disease mentions that occur in the same sentence as 'Co-occurrence', or as 'Non-Co-occurrence' otherwise. In the first phase, the relation instances are constructed on both mention levels. In the second phase, we employ a hybrid feature set to classify the relation instances at both of these mention levels using the combination of two Machine Learning (ML) classifiers (Support Vector Machine (SVM) and J48 Decision tree). This system is entirely corpus dependent and does not rely on information from external resources in order to boost its performance. We achieved good results, which are comparable with the other state-of-the-art CID relation extraction systems on the BioCreative V corpus. Furthermore, our system achieves the best performance on the Non-Co-occurrence mention level. PMID- 30296493 TI - It's complicated... m6A-dependent regulation of gene expression in cancer. AB - Cellular function relies on multiple pathways that are coordinated to ensure the proper execution of gene expression networks. Failure to coordinate the multiple programs active in the cell can have catastrophic consequences and lead to diseases such as cancer. At the post-transcriptional level, RNA modifications play important roles in the regulation of gene expression. N6-methyladenosine (m6A) is the most abundant internal messenger RNA (mRNA) modification and has gained increasing interest in the last few years as a dynamic regulator of RNA metabolism. Modifications regulate all stages of the RNA life cycle, from transcription to decay. Recent studies have pointed to the role of RNA methylation in cancer initiation and progression, and aberrant modification has served as a biomarker of early-stage diagnosis in several cancers. Here, we review the regulation of m6A, disruptions to methylation-dependent pathways that influence carcinogenesis, and potential avenues for m6A-related therapeutic strategies. PMID- 30296492 TI - Using Scipion for stream image processing at Cryo-EM facilities. AB - Three dimensional electron microscopy is becoming a very data-intensive field in which vast amounts of experimental images are acquired at high speed. To manage such large-scale projects, we had previously developed a modular workflow system called Scipion (de la Rosa-Trevin et al., 2016). We present here a major extension of Scipion that allows processing of EM images while the data is being acquired. This approach helps to detect problems at early stages, saves computing time and provides users with a detailed evaluation of the data quality before the acquisition is finished. At present, Scipion has been deployed and is in production mode in seven Cryo-EM facilities throughout the world. PMID- 30296494 TI - Epigenetic dynamic during endochondral ossification and articular cartilage development. AB - Within the last decade epigenetics has emerged as fundamental regulator of numerous cellular processes, including those orchestrating embryonic and fetal development. As such, epigenetic factors play especially crucial roles in endochondral ossification, the process by which bone tissue is created, as well during articular cartilage formation. In this review, we summarize the recent discoveries that characterize how DNA methylation, histone post-translational modifications and non-coding RNA (e.g., miRNA and lcnRNA) epigenetically regulate endochondral ossification and chondrogenesis. PMID- 30296495 TI - Fertility, fecundity and the creative instinct. PMID- 30296496 TI - Mutant p53 prevents GAPDH nuclear translocation in pancreatic cancer cells favoring glycolysis and 2-deoxyglucose sensitivity. AB - Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive and devastating human malignancies. In about 70% of PDACs the tumor suppressor gene TP53 is mutated generally resulting in conformational changes of mutant p53 (mutp53) proteins, which acquire oncogenic functions triggering aggressiveness of cancers and alteration of energetic metabolism. Here, we demonstrate that mutant p53 prevents the nuclear translocation of the glycolytic enzyme glyceraldehyde-3 phosphate dehydrogenase (GAPDH) stabilizing its cytoplasmic localization, thus supporting glycolysis of cancer cells and inhibiting cell death mechanisms mediated by nuclear GAPDH. We further show that the prevention of nuclear localization of GAPDH is mediated by both stimulation of AKT and repression of AMPK signaling, and is associated with the formation of the SIRT1:GAPDH complex. By using siRNA-GAPDH or an inhibitor of the enzyme, we functionally demonstrate that the maintenance of GAPDH in the cytosol has a critical impact on the anti apoptotic and anti-autophagic effects driven by mutp53. Furthermore, the blockage of its mutp53-dependent cytoplasmic stabilization is able to restore the sensitivity of PDAC cells to the treatment with gemcitabine. Finally, our data suggest that mutp53-dependent enhanced glycolysis permits cancer cells to acquire sensitivity to anti-glycolytic drugs, such as 2-deoxyglucose, suggesting a potential personalized therapeutic approach in human cancers carrying mutant TP53 gene. PMID- 30296497 TI - NF-YA enters cells through cell penetrating peptides. AB - Cell Penetrating Peptides -CPPs- are short aminoacidic stretches present in proteins that have the ability to translocate the plasma membrane and facilitate delivery of various molecules. They are usually rich in basic residues, and organized as alpha helices. NF-Y is a transcription factor heterotrimer formed by two Histone Fold Domain -HFD- subunits and the sequence-specific NF-YA. NF-YA possesses two alpha-helices rich in basic residues. We show that it efficiently enters cells at nanomolar concentrations in the absence of carrier peptides. Mutagenesis identified at least two separate CPPs in the A1 and A2, which overlap with previously identified nuclear localization signals (NLS). The half-life of the transduced protein is short in human cancer cells, longer in mouse C2C12 myoblasts. The internalized NF-YA is capable of trimerization with the HFD subunits and binding to the target CCAAT box. Functionality is further suggested by protein transfection in C2C12 cells, leading to inhibition of differentiation to myotubes. In conclusion, NF-YA contains CPPs, hinting at novel -and unexpected properties of this subunit. PMID- 30296498 TI - The cytosolic peroxisome-targeting signal (PTS)-receptors, Pex7p and Pex5pL, are sufficient to transport PTS2 proteins to peroxisomes. AB - Proteins harboring peroxisome-targeting signal type-2 (PTS2) are recognized in the cytosol by mobile PTS2 receptor Pex7p and associate with a longer isoform Pex5pL of the PTS1 receptor. Trimeric PTS2 protein-Pex7p-Pex5pL complexes are translocated to peroxisomes in mammalian cells. However, it remains unclear whether Pex5pL and Pex7p are sufficient cytosolic components in transporting of PTS2 proteins to peroxisomes. Here, we construct a semi-intact cell import system to define the cytosolic components required for the peroxisomal PTS2 protein import and show that the PTS2 pre-import complexes comprising Pex7p, Pex5p, and Hsc70 isolated from the cytosol of pex14 Chinese hamster ovary cell mutant ZP161 is import-competent. PTS2 reporter proteins are transported to peroxisomes by recombinant Pex7p and Pex5pL in semi-intact cells devoid of the cytosol. Furthermore, PTS2 proteins are translocated to peroxisomes in the presence of a non-hydrolyzable ATP analogue, adenylyl imidodiphosphate, and N-ethylmaleimide, suggesting that ATP-dependent chaperones including Hsc70 are dispensable for PTS2 protein import. Taken together, we suggest that Pex7p and Pex5pL are the minimal cytosolic factors in the transport of PTS2 proteins to peroxisomes. PMID- 30296499 TI - Clostridium difficile toxin B induces senescence in enteric glial cells: A potential new mechanism of Clostridium difficile pathogenesis. AB - Clostridium difficile infection (CDI) causes nosocomial/antibiotic-associated diarrhea and pseudomembranous colitis, with dramatic incidence/mortality worldwide. C. difficile virulence factors are toxin A and toxin B (TcdB) which cause cytopathic/cytotoxic effects and inflammation. Until now studies were focused on molecular effects of C. difficile toxins (Tcds) on different cells while unexplored aspect is the status/fate of cells that survived their cytotoxicity. Recently we demonstrated that enteric glial cells (EGCs) are susceptible to TcdB cytotoxicity, but several EGCs survived and were irreversibly cell-cycle arrested and metabolically active, suggesting that EGCs could became senescent. This is important because allowed us to evaluate the not explored status/fate of cells surviving Tcds cytotoxicity, and particularly if TcdB induces senescence in EGCs. Rat-transformed EGCs were treated with 10 ng/ml TcdB for 6 h-48 h, or for 48 h, followed by incubation for additional 4 or 11 days in absence of TcdB (6 or 13 total days). Senescence markers/effectors were examined by specific assays. TcdB induces senescence in EGCs, as demonstrated by the senescence markers: irreversible cell-cycle arrest, senescence-associated-beta galactosidase positivity, flat morphology, early and persistent DNA damage (ATM and H2AX phosphorylation), p27 overexpression, pRB hypophosphorylation, c-Myc, cyclin B1, cdc2 and phosphorylated-cdc2 downregulation, Sirtuin-2 and Sirtuin-3 overexpression. TcdB-induced EGC senescence is dependent by JNK and AKT activation but independent by ROS, p16 and p53/p21 pathways. In conclusion, TcdB induces senescence in EGCs. The extrapolation of these results to CDI leads to hypothesize that EGCs that survived TcdB, once they have acquired a senescence state, could cause irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and tumors due to persistent inflammation, transfer of senescence status and stimulation of pre-neoplastic cells. PMID- 30296500 TI - Cofilin-1 signaling mediates epithelial-mesenchymal transition by promoting actin cytoskeleton reorganization and cell-cell adhesion regulation in colorectal cancer cells. AB - Colorectal cancer (CRC) is frequently a lethal disease because of metastasis. Actin cytoskeletal rearrangement is an essential step in cell migration during activation of the epithelial-mesenchymal transition (EMT) program, which is associated with metastatic properties of cancer cells. Cofilin-1 protein modulates actin dynamics by promoting actin treadmilling, thereby driving membrane protrusion and cell migration and invasion. However, the role of cofilin 1 during EMT in CRC is unknown. Here, we show that cofilin-1 and p-cofilin-1 have distinct subcellular distribution in EMT cells, as determined by super-resolution microscopy images, indicating distinct roles in different areas of cells. Silenced cofilin-1 cells treated with TGF-beta (siCofilin-1/TGF-beta) evaded p LIMK2-p-cofilin-1 status, leading to recovery of E-cadherin and claudin-3 at the cell-cell contact and their respective protein levels, actin reorganization, and decreased mesenchymal protein level. Furthermore, siCofilin-1/TGF-beta cells exhibited decreased migration and invasion rates as well as MMP-2 and -9 activity and augmented focal adhesion size. The expression of an inactive phospho-cofilin 1 mimetic (S3E) reduced E-cadherin and claudin-3 in cell-cell contacts, reduced their protein levels, and increased vimentin protein. Based on our findings, we suggest that cofilin-1 is crucial to switching from epithelial to mesenchymal like morphology and cell migration and invasion by regulating actin cytoskeleton organization through activation of RhoA-LIMK2-cofilin-1 signaling, impacting the cell-cell adhesion organization of colon cancer cells in EMT. PMID- 30296501 TI - Recurrent Urinary Tract Infections are Associated With Frailty in Older Adults. AB - OBJECTIVE: To understand the relationship between frailty, age, and recurrent urinary tract infections (rUTIs). MATERIALS AND METHODS: The Timed Up and Go Test (TUGT), a measure of frailty, was administered to all adults aged >=65 presenting to an academic nononcologic urology practice from December 2015 to January 2018. TUGT was categorized as fast (<=10 seconds), intermediate (11-14 seconds) or slow (>=15 seconds). The TUGT and other clinical data were abstracted from the medical record using direct queries supplemented with chart review. Logistic regression was used to determine the relationship between frailty, age, and the diagnosis of rUTIs in our clinic population. RESULTS: There were 136 americans adults with and 2824 americans adults without a diagnosis of rUTIs. Individuals with rUTIs had slower TUGT times (13.8 +/- 10.4 seconds compared to 10.8 +/- 4.52 seconds, P <.01) and were more likely to be classified as slow, or "frail" (27.2% vs 10.8%). In multivariate analysis, slow TUGT times were associated with a diagnosis of rUTIs (adjusted OR 2.0, 95% CI 1.2-3.3), while age was not a statistically significant predictor of this diagnosis (adjusted OR 1.3, 95% CI 0.7-2.2 for aged >=81 years). CONCLUSION: Older adults with a diagnosis of rUTIs are significantly more frail compared to those with other nononcologic urologic diagnoses. Frailty (adjusted for age), was significantly associated with rUTIs, while age (adjusted for frailty) was not. Furthermore, frailty (rather than age) may be important to consider when caring for and treating americans adults with rUTIs. PMID- 30296502 TI - Surgical Management of Patients with Advanced Germ Cell Tumors Following Salvage Chemotherapy: Memorial Sloan Kettering Cancer Center (MSKCC) Experience. AB - OBJECTIVE: To characterize clinical and pathologic outcomes of cisplatin refractory or relapsed germ cell tumor (GCT) patients who underwent retroperitoneal lymph node dissection (RPLND) following salvage chemotherapy with either conventional or high dose regimens. METHODS: Data were reviewed to identify all patients treated with TIP or TICE salvage chemotherapy between 1994 and 2011(n = 184) at our institution. We report clinicopathologic and outcomes data on 131 patients who were further managed with surgical resection. Using Cox proportional hazards models, predictors of disease-specific survival (DSS) were analyzed. RESULTS: Median follow-up was 7.3 years. Of the 112 patients who underwent postsalvage chemotherapy RPLND, histology was reported as viable GCT in 30 (27%), teratoma only in 26 (23%) and fibrosis in 56 (50%). 5-year DSS for the entire cohort was 74% (95% confidence interval 63%-80%). On multivariable analysis, viable GCT histology at RPLND or extra-RPLND resection predicted for worse DSS (hazard ratio 7.37, P = .003). CONCLUSIONS: Our data suggest that approximately half of the patient with cisplatin-refractory or relapsed GCT salvaged with TIP or TICE chemotherapy and evidence of residual disease are at risk of harboring either viable GCT or teratoma. This finding underlines the critical role of surgery in the multimodality approach to the management of this advanced disease entity. If retroperitoneal disease exists prior to salvage chemotherapy, we recommend postchemotherapy resection in all eligible patients. PMID- 30296503 TI - Renal Hilar Lesions: Biological Implications for Complex Partial Nephrectomy. AB - OBJECTIVE: To perform a comprehensive histopathologic review of sporadic resected solitary cT1 renal masses comparing those with and without radiographic involvement of the hilum. MATERIALS AND METHODS: A prospectively maintained database was queried for all cT1 renal masses undergoing resection classified per the R.E.N.A.L. nephrometry score. Hilar masses were defined as tumors that abut the main renal artery or vein on cross-sectional imaging. Demographic, treatment, renal mass, and histopathologic characteristics were compared between hilar and nonhilar renal masses. Multivariate regression model analyses were performed to assess factors associated with renal mass upstaging and disease recurrence. RESULTS: A total of 1324 stage 1 renal masses met criteria for analysis of which 226 (17.1%) were defined as hilar. Hilar masses were larger, scored with higher complexity, and more likely to undergo a radical nephrectomy. On histopathologic analysis, we found no difference between hilar and nonhilar masses regarding the incidence of malignancy, presence of high nuclear grade, or risk of upstaging. On multivariate analysis, a tumor's hilar location was not associated with upstaging or disease recurrence. CONCLUSION: We present a comprehensive histopathologic review of a large cohort of cT1 hilar lesions noting no difference in the risk of malignancy, high nuclear grade, upstaging, or recurrence when compared to nonhilar lesions. Together, these data suggest that there is no compelling cancer specific rationale to perform a radical nephrectomy when managing renal hilar tumors. PMID- 30296504 TI - Dopamine genetic risk is related to food addiction and body mass through reduced reward-related ventral striatum activity. AB - The prevalence rate of obesity continues to rise in the U.S., but effective treatment options remain elusive resulting in increased emphasis on prevention. One such area of prevention research capitalizes on the relatively novel behavioral construct of food addiction, which has been implicated in obesity. Food addiction reflects an individual's propensity for compulsive eating despite negative consequences, and shares not only symptoms with both eating and substance use disorders but also genetic and neural correlates within neural reward-circuitry modulated by dopamine. Here, we examined associations between food addiction scores, body mass index (BMI), reward-related ventral striatum activity, and a polygenic score approximating dopamine signaling in 115 non Hispanic Caucasian young adult university students. As predicted, polygenic dopamine scores were related to ventral striatum activity, which in turn was associated with higher food addiction scores. In addition, food addiction was related to BMI. An exploratory post-hoc path analysis further indicated that polygenic scores were indirectly related to both food addiction and BMI, in part, through ventral striatum activity. Collectively, our results provide evidence supporting the utility of food addiction in weight gain prevention research by establishing links with known risk-related neural and genetic biomarkers. PMID- 30296505 TI - Association between eating frequency and eating behaviours related to appetite from 4 to 7 years of age: Findings from the population-based birth cohort generation XXI. AB - The examination of specific characteristics of eating habits in childhood and its influence on eating behaviours is needed to better understand the establishment of appetite-related eating behaviours. This study aimed to assess the association between eating frequency (EF) (main meals vs. snacks) at 4 and 7y and problematic eating behaviours and appetite-related eating behaviours at 7y. The analysis included 1359 children from the birth cohort Generation XXI who provided 3-day food diaries, at both ages, and complete information on the Child Eating Behaviour Questionnaire, at 7y. Problematic eating behaviours were assessed using parental perception of child's poor eating (including not eating enough, eating too slow or overeating) at both ages. A time-of-day approach was used to distinguish main meals from snacks. A cross-lagged analysis was performed to check the direction of the association between EF and parental concerns regarding problematic eating behaviours. Associations between EF and appetite-related eating behaviours were evaluated through linear regression models. Between 4 and 7y a moderate tracking of EF was described as well as a strong tracking of parental concerns. We found a bidirectional relationship between EF and parental concerns. Prospectively, a higher frequency of snacks at 4y was independently associated with higher scores in 'Desire to Drink' at 7y (beta = 0.051, 95%CI:0.009; 0.093). At 7y, a higher EF had a positive association with 'Satiety Responsiveness' but an inverse association with 'Enjoyment of Food'. A higher number of main meals had a positive association with 'Enjoyment of Food' and 'Food Responsiveness'. In conclusion, children who had more eating occasions seem to have more food-avoidance behaviours, traits that might protect these children from gaining excessive weight. PMID- 30296506 TI - Response characteristics of the cat somatosensory cortex following the mechanical stimulation to endodontically treated teeth with overextension. AB - The overextension of filling materials may take place accidentally during an endodontic root canal treatment. Previous studies to understand the correlation between overfilling and paresthesia of teeth were inconsistent. In this study, an intrinsic signal optical imaging technique was employed as the objective tool to compare the response characteristics of the cat somatosensory cortex following mechanical stimulation applied to endodontically treated teeth with overextension (ETTWO) and natural teeth. Based on the evoked cortical response, the signal strength of the ETTWO was found to be significantly higher than that of the natural teeth. However, the tactile threshold of the ETTWO was significantly lower than that of the natural teeth. It was concluded that the tactile function of ETTWO is more sensitive than that of natural teeth, and that the overextension of filling materials can cause hyperesthesia of teeth after root canal treatment. PMID- 30296507 TI - Aging alters glucose uptake in the naive and injured rodent spinal cord. AB - Aging results in increased activation of inflammatory glial cells and decreased neuronal viability following spinal cord injury (SCI). Metabolism and transport of glucose is also decreased with age, although the influence of age on glucose transporter (GLUT) expression or glucose uptake in SCI is currently unknown. We therefore performed [18F]Fluorodeoxyglucose (FDG) PET imaging of young (3 month) and middle-aged (12 month) rats. Glucose uptake in middle-aged rats was decreased compared to young rats at baseline, followed by increased uptake 14 days post contusion SCI. qRT-PCR and protein analysis revealed an association between 14 day glucose uptake and 14 day post-injury inflammation. Further, gene expression analysis of neuron-specific GLUT3 and non-specific GLUT4 (present on glial cells) revealed an inverse relationship between GLUT3/4 gene expression and glucose uptake patterns. Protein expression revealed increased GLUT3 in 3 month rats only, consistent with age related decreases in glucose uptake, and increased GLUT4 in 12 month rats only, consistent with age related increases in inflammatory activity and glucose uptake. Inconsistencies between gene and protein suggest an influence of age-related impairment of translation and/or protein degradation. Overall, our findings show that age alters glucose uptake and GLUT3/4 expression profiles before and after SCI, which may be dependent on level of inflammatory response, and may suggest a therapeutic avenue in addressing glucose uptake in the aging population. PMID- 30296508 TI - Substitution therapy with amphetamine-isotherapic attenuates amphetamine toxicological aspects of addiction. AB - INTRODUCTION: amphetamine (AMPH) is related to development of addiction, anxiety like behaviors and impairments of memory after chronic use. In the current experiment, an ultra-high dilution (10-24mg/mL) of AMPH was used, consisting of the AMPH isotherapic (AMPH-ISO), which can be used as a replacement therapy to treat AMPH addiction. AIM: To verify the influence of AMPH-ISO on toxicological aspects of AMPH addiction. METHODS: Rats received d,l-AMPH (4.0 mg/kg, i.p.) in the conditioned place preference (CPP) paradigm (8 days). Then, half of each experimental group (AMPH or saline) received AMPH-ISO/vehicle (0.2 mL per rat, once a day), for fourteen days. On the fifteenth day, animals were re-assessed in the CPP paradigm (to verify relapse behaviors) after a single dose of AMPH (2.0 mg/kg). Subsequently, anxiety-like behaviors were quantified, followed by ex vivo assays in the pre-frontal cortex. RESULTS: AMPH-ISO prevented relapse-like behavior of AMPH and reduced anxiety-like behavior per se in animals co-treated with AMPH. Molecular analysis evidenced that AMPH-ISO modulated dopaminergic targets (dopamine transporter, tyrosine hydroxylase and D1-R), whose immunoreactivity was increased by AMPH. Also, AMPH-ISO increased catalase activity and NPSH levels and reduced lipid peroxidation and protein carbonyl levels in the prefrontal cortex. CONCLUSION: This study shows that an ultra-high dilution of AMPH may be a useful alternative which can contribute with AMPH addiction treatment.

AB - Paeonol is a natural flavonoid isolated from Moutan Cortex, which has been found to exhibit antioxidant, anti-apoptotic, anti-aging and anti-inflammatory bioactivities. Herein, we investigated the nephroprotective efficacy of paeonol against Pb-induced toxicity and elucidated the potential mechanisms. The results revealed that paeonol significantly ameliorated renal dysfunction and histology changes of Pb-treated mice. Paeonol inhibited oxidative stress and increased activities of antioxidant enzyme in the kidneys of Pb-treated mice. Paeonol decreased the nuclear factor-kappaB activation and over-production of inflammatory cytokines tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6). Paeonol suppressed endoplasmic reticulum (ER) stress in kidneys of in the Pb treatment group and primary kidney mesangial cells. Moreover, paeonol increased the denosine 5'-monophosphate-activated protein kinase (AMPK) phosphorylation and decreased the activations of glycogen synthase kinase-3 (GSK 3), protein kinase RNA-like ER kinase (PERK), inositol-requiring protein-1 (IRE1), c-jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (MAPK). These results were further confirmed in primary kidney mesangial cells. Taken together, these findings indicate that paeonol could protect kidney form Pb induced injury by inhibiting oxidative stress, ER stress and inflammation via the AMPK and GSK-3 pathway. Paeonol might be a potential therapeutic agent to inhibit ER stress-associated inflammation in lead-stimulated kidneys.

PMID- 30296518 TI - Diagnosis of T-cell mediated kidney rejection in formalin fixed paraffin embedded tissues using RNA-Seq based machine learning algorithms. AB - Molecular diagnosis is being increasingly used into transplant pathology to render more objective and quantitative determinations that also provide mechanistic and prognostic insights. This study performed RNA-Seq on biopsies from kidneys with stable function (STA) and biopsies with classical findings of T cell mediated rejection (TCMR). Machine learning tools were used to develop prediction models for distinguishing TCMR and STA samples using the top genes identified by DSeq2. The prediction models were tested on 703 biopsies with Affymetrix chip gene expression profiles available in the public domain. Linear Discriminant Analysis (LDA) predicted TCMR in 55/67 biopsies labeled TCMR, 65/105 biopsies designated as antibody-mediated rejection (ABMR). The random forest and support vector machine models showed comparable performance. These data illustrate the feasibility of using RNA-Seq for molecular diagnosis of TCMR in formalin fixed tissue. Application of the derived diagnostic algorithms to publicly available datasets demonstrates frequent co-existence of TCMR in biopsies designated as ABMR. This under-recognition of TCMR in renal allograft biopsies has significant implications with respect to patient care. PMID- 30296519 TI - A review of the incidence of adenocarcinoma detected during surveillance for Barrett's esophagus. AB - The objective of this study is to provide an up to date estimate of the incidence of adenocarcinoma detected during surveillance of Barrett's esophagus. Fifty-five longitudinal studies involving approximately 61000 patients were reviewed. A general linear model analyses with Poisson link function was used to study how the number of cancer cases detected depended on study details. The studies appeared to follow the same statistical model, and the probability of developing Barrett's carcinoma during surveillance was found to depend on the following variables: how Barrett's metaplasia was defined, the number of patients studied, the mean time of follow-up and the fraction of patients followed at least 5years. The model derived from all the studies predicted that the per person probability of developing cancer in 5years of complete follow-up is approximately .0012.

PMID- 30296520 TI - HMGB2 promotes the malignancy of human gastric Cancer and indicates poor survival outcome. AB - HMGB2 is an important protein in carcinogenesis. However, little is known regarding the specific role of HMGB2 in gastric cancer. In present study, HMGB2 expression was evaluated in 198 primary gastric cancer tissues and their adjacent non-tumor controls. The correlation between HMGB2 expression and clinic pathological features and survival was assessed. The effect of HMGB2 on cell proliferation, invasion, and glycolysis was examined in vitro. The expression of HMGB2 was significantly increased in human gastric cancer when compared with non tumor tissues (P<.001). High HMGB2 expression correlated with large tumor size (P0.001), advanced T stage (P=.007), and present of lymph node metastasis (P=.004). Moreover, high HMGB2 expression was validated as an independent prognostic factor in both univariate and multivariate analysis (P<.05). Experimentally, silencing HMGB2 expression by stable transfected shRNA significantly decreased the proliferation, invasion and glycolysis of gastric cancer cells. In conclusion, HMGB2 is a novel prognostic biomarker for survival in gastric cancer, and knockdown HMGB2 expression in gastric cancer cells attenuated proliferation and invasion, and impaired glycolysis in gastric cancer cells. Hence, HMGB2 may serves as a new biomarker and potential therapeutic target for gastric cancer. PMID- 30296521 TI - IDH mutation status in a series of 88 head and neck chondrosarcomas: different profile between tumors of the Skull Base and tumors involving the facial skeleton and the Layngotracheal tract. AB - Chondrosarcomas are rare primary malignant bone tumors that involve the head and neck region in 1% to 12% of cases. Central conventional chondrosarcoma is the most common subtype and is associated with isocitrate dehydrogenase 1 and 2 (IDH1 and IDH2) gene mutations in 50% to 60% of cases. We aimed to define the frequency of IDH1 and IDH2 gene mutations in a multicenter series of 88 cases of chondrosarcoma of the head and neck, including tumors involving the base of the skull (n=30), the facial skeleton (n=11), and the laryngeal and tracheal cartilages (n=47). Petrous bone and cricoid cartilage were the most frequently involved sites for chondrosarcomas of the skull base and laryngotracheal tract (respectively 43.3% and 31.9%). Overall, 64.9% of craniofacial chondrosarcomas featured IDH mutations, with a high rate for skull-base tumors (85.7%) but no IDH mutations in tumors of the facial skeleton. This different mutational profile could be related to the type of ossification, the bones of the base of the skull mainly resulting from endochondral ossification and those of the face from intramembranous ossification. Conversely, mutation was infrequent in chondrosarcomas involving the laryngeal and tracheal cartilages (11.8% of 47 cases). Evaluation of IDH mutation status may be a useful diagnostic tool for bone tumors of the skull base, which are most often assessable with only small biopsy samples. The low rate of IDH mutations observed in laryngotracheal chondrosarcomas suggests a different mode of tumorigenesis needing further exploration. PMID- 30296522 TI - Loss of expression of MU-protocadherin and protocadherin-24 in sporadic and hereditary non polyposis colorectal cancers (HNPCC). AB - Colorectal cancer (CRC) is a neoplastic disease in which normal mucosa undergoes a process of malignant transformation due to the progressive accumulation of molecular alterations affecting proto-oncogenes and onco-suppressor genes. Some of these modifications exert their carcinogenic potential by promoting a constitutive activation of the beta-catenin signaling proliferation pathway and, when present, loss of cadherin expression also significantly contributes to the same effect. Using a combined approach of molecular and immunohistochemical analysis, we have previously demonstrated that the majority of sporadic CRCs exhibit a down-regulated expression of a cadherin, named MU-protocadherin, that is generally observed in association with a higher proliferation rate and a worst prognosis. The aim of this report was to perform a comparative immunohistochemical assessment of MU-protocadherin and a similar cadherin, named protocadherin-24, in sporadic CRC and hereditary non polyposis colorectal cancer (HNPCC). The data obtained put in evidence that double negative CRCs, lacking both the analyzed protocadherins, are more represented among sporadic tumors whereas double positive CRCs, maintaining their expression, exhibit an opposite trend. As expected, loss of protocadherin expression was accompanied by nuclear localization of beta-catenin and increased positivity of the Ki-67 proliferation marker. This finding is consistent with the different clinical evolution of the two considered CRC sets according to which HNPCC patients experience a better prognosis as compared to those affected by a sporadic CRC. PMID- 30296523 TI - PD-L1 expression on tumor cells associated with favorable prognosis in surgically resected esophageal squamous cell carcinoma. AB - There is limited evidence regarding the relationship between programmed cell death ligand 1 (PD-L1) expression on tumor cells (TCs) and prognosis of esophageal squamous cell carcinoma (ESCC). This retrospective study aimed to investigate the clinical significance of PD-L1 expression in ESCC. To assess PD L1 expression, we conducted immunohistochemistry studies using a tissue microarray encompassing 233 ESCC cases, stage I, II, and III, with detailed clinical data. PD-L1 expression on TCs was observed in 55.4% (129 of 233) of ESCC cases and was not associated with clinicopathological factors. ESCC patients with PD-L1-positive tumors showed significantly better overall survival (OS) and disease-free survival (DFS) than those with PD-L1-negative tumors (P=.023, P=.026, respectively). When patients were stratified into those with stage I-II (127, 54.5%) and stage III (106, 45.5%) disease and those without (134, 57.5%) and with (99, 42.5%) lymph node metastasis, the prognostic effect was inconsistent. The OS and DFS of patients with positive PD-L1 expression were significantly better in patients with stage I-II disease (P=.021, P=.015, respectively) and without lymph node metastasis (P=.009, P=.07, respectively) than their counterparts. Our results showed that PD-L1 expression on TCs was an independent predictor of prognosis of ESCC patients. However, the effect varied in patients with different stages and lymph node status. Positive PD-L1 expression was a favorable predictor in ESCC patients with stage I-II disease or without lymph node metastasis but not in patients with stage III disease or lymph node metastasis.

PMID- 30296528 TI - Angiotensin receptor (AT2R) agonist C21 prevents cognitive decline after permanent stroke in aged animals-A randomized double- blind pre-clinical study. AB - Post stroke cognitive impairment (PSCI) is an understudied, long-term complication of stroke, impacting nearly 30-40% of all stroke survivors. No cure is available once the cognitive deterioration manifests. To our knowledge, this is the first study to investigate the long-term effects of C21 treatment on the development of PSCI in aged animals. Treatments with C21 or vehicle were administered orally, 24 h post-stroke, and continued for 30 days. Outcome measures for sensorimotor and cognitive function were performed using a sequence of tests, all blindly conducted and assessed at baseline as well as at different time points post-stroke. Our findings demonstrate that the angiotensin receptor (AT2R) agonist C21 effectively prevents the development of PSCI in aged animals. PMID- 30296529 TI - Understanding nociception-related phenotypes in adult zebrafish: behavioral and pharmacological characterization using the acetic acid model. AB - Pain, a severely debilitating symptom of many human disorders, is a growing, unmet biomedical problem. Although the use of zebrafish (Danio rerio) to investigate both behavioral and physiological nociception-related responses is expanding rapidly, the characterization of behavioral phenotypes that reflect injury location is still poorly explored, making the results of such studies difficult to interpret. Here, we characterize putative nociception-related behavioral phenotypes in adult zebrafish following an intraperitoneal (i.p.) administration of acetic acid, a well-established protocol for visceral pain in rodents. Acetic acid (2.5 and 5.0%) induced an abdominal constriction-like response, which was assessed by measuring a body curvature index. Moreover, all doses tested (0.5-5.0%) reduced distance traveled and vertical activity in the novel tank test. Freezing duration increased following 5.0% acetic acid, whereas fish injected with 1.0, 2.5, and 5.0% spent more time in top area of the tank. Both morphine (an opioid analgesic) and diclofenac (a nonsteroidal anti inflammatory drug, NSAID) prevented the 5.0% acetic acid-induced changes in body curvature index, whereas naloxone blocked these effects of morphine. Overall, zebrafish exposed to a single acetic acid i.p. injection display abnormal body curvature and specific changes in behavioral parameters sensitive to anti nociceptive pharmacological modulation. We suggest that the abdominal constriction-like response represents a novel specific nociceptive-related phenotype in zebrafish. In general, our findings support the growing utility of zebrafish in translational pain research and antinociceptive drug discovery. PMID- 30296530 TI - Adolescent social isolation increases cocaine seeking in male and female mice. AB - Childhood and adolescent adversity are associated with a wide range of psychiatric disorders, including an increased risk for substance abuse. Despite this, the mechanisms underlying the ability of chronic stress during adolescence to alter reward signaling remains largely unexplored. Understanding how adolescent stress increases addiction-like phenotypes could inform the development of targeted interventions both before and after drug use. The current study examined how prolonged isolation stress, beginning during adolescence, affected behavioral and neuronal underpinnings to the response to cocaine in male and female mice. Adolescent-onset social isolation did not alter the ability of mice to learn an operant response for food, nor influence food self administration or motivation for food on a progressive ratio schedule. However, male and female social isolation mice exhibited an increase in motivation for cocaine and cocaine seeking during a cue-induced reinstatement session. Additionally, we demonstrated that adolescent-onset social isolation increased cocaine-induced neuronal activation, as assessed by c-Fos expression, within the nucleus accumbens core and shell, ventral pallidum, dorsal bed nucleus of the stria terminalis, lateral septum and basolateral amygdala. Taken together, the present studies demonstrate that social isolation stress during adolescence augments the behavioral responses to cocaine during adulthood and alters the responsiveness of reward-related brain circuitry. PMID- 30296531 TI - Risky decision-making is associated with impulsive action and sensitivity to first-time nicotine exposure. AB - Excessive risk-taking is common in multiple psychiatric conditions, including substance use disorders. The risky decision-making task (RDT) models addiction relevant risk-taking in rats by measuring preference for a small food reward vs. a large food reward associated with systematically increasing risk of shock. Here, we examined the relationship between risk-taking in the RDT and multiple addiction-relevant phenotypes. Risk-taking was associated with elevated impulsive action, but not impulsive choice or habit formation. Furthermore, risk-taking predicted locomotor sensitivity to first-time nicotine exposure and resilience to nicotine-evoked anxiety. These data demonstrate that risk preference in the RDT predicts other traits associated with substance use disorder, and may have utility for identification of neurobiological and genetic biomarkers that engender addiction vulnerability. PMID- 30296532 TI - Disruption of the NMDA receptor GluN2A subunit abolishes inflammation-induced depression. AB - Recent reports have demonstrated that lipopolysaccharide (LPS)-induced depressive like behaviour is mediated via NMDA receptor. In this study, we further investigated the role of GluN2 A subunit of NMDA receptor in synaptic processes in the prefrontal cortex (PFC) and hippocampus of GluN2 A knockout (KO) mice in LPS-induced depressive-like behavior. Our data suggest that LPS-treated mice, lacking GluN2 A subunit, did not exhibit depressive-like behaviour. This was accompanied by unaltered levels of IL-6 and significant changes in neuroplasticity markers and glutamate receptor subunits composition in PFC and hippocampus. In particular, an immune challenge in GluN2 A KO mice resulted in unchanged PSA-NCAM levels and proBDNF increase in both brain structures as well as in increase in BDNF levels in hippocampus. Furthermore, the absence of GluN2 A resulted in increased levels of all NCAM isoforms in PFC upon LPS which was followed with a decrease in GluN1 and GluN2B subunits. The levels of AMPA receptor subunits (GluA1, GluA3, and GluA4) in the hippocampus of GluN2 A mice were unaltered upon the treatment and abundantly present in the PFC of KO mice. These results indicate that the GluN2 A subunit is critical in neuroinflammation related depression, that its absence abolishes LPS-induced depressive phenotype, sustains PSA-NCAM levels, increases proBDNF signalling in the PFC and hippocampus and potentiates synaptic stabilization through NCAM in the PFC upon an immune challenge. PMID- 30296534 TI - Approaches to limit systemic antibiotic use in acne: Systemic alternatives, emerging topical therapies, dietary modification, and laser and light-based treatments. AB - Acne is one of the most common diseases worldwide and affects approximately 50 million individuals in the United States. Oral antibiotics are the most common systemic agent prescribed for the treatment of acne. However, their use may be associated with a variety of adverse outcomes including bacterial resistance and disruption of the microbiome. As a result, multiple treatment guidelines call for limiting the use of oral antibiotics in the treatment of acne, although actual prescribing often does not follow these guidelines. In this review, the rationale for concerns regarding the use of oral antibiotics for the management of acne is reviewed. In addition, we will discuss our approach to complying with the intent of the guidelines, with a focus on novel topical agents, dietary modification, laser and light-based modalities, and systemic medications such as spironolactone, combined oral contraceptives, and oral isotretinoin. PMID- 30296533 TI - The use of topical rapamycin in the treatment of superficial lymphatic malformations. AB - BACKGROUND: The superficial lymphatic component of vascular malformations poses a significant treatment challenge. It is responsible for the majority of symptoms presented and to date there is no consensus regarding treatment. OBJECTIVE: To evaluate the effectiveness of topical rapamycin in treating superficial lymphatic malformations (LM). METHODS: A case series study was performed of patients with superficial LM, treated with topical rapamycin. The clinical characteristics of the patients and the concentration and application mode of the drug were recorded. The changes in the signs and symptoms observed, and associated adverse effects, were then noted and analysed. RESULTS: The study population consisted of 11 patients, average age 10.5 years. All were treated with topical rapamycin, in six cases at 1%, in one at 0.8% and in four at 0.4%. Changes in the clinical appearance of the lesions were observed in all patients. The associated symptoms, present in 9 of the 11 patients, improved in every case. The mean follow-up time was 16.1 months. LIMITATIONS: This study is retrospective, with a small sample size and considerable heterogeneity of lesions and treatment approaches. CONCLUSIONS: Treatment with topical rapamycin modifies the clinical appearance and alleviates the symptoms of superficial LM. PMID- 30296535 TI - Relative efficacy of systemic treatments for atopic dermatitis. AB - BACKGROUND: Systemic medications are often required for severe atopic dermatitis (AD) refractory to topical therapies. Biologic medications are a recent advancement in the field and a comparison to traditional systemic approaches would be beneficial. OBJECTIVE: To compare efficacies of systemic therapies for the treatment of AD METHODS: A systematic literature review was performed using Medline, Ovid and Embase. Randomized controlled trials looking at the efficacy of systemic treatments for AD in adults and children were included. RESULTS: A total of 41 studies met criteria and were included in our final analysis. Consistent improvements in Eczema Area and Severity Index (EASI) and Scoring Atopic Dermatitis (SCORAD) were reported with dupilumab and cyclosporine. Phase 2 clinical trials for lebrikizumab and tralokinumab were effective and would benefit from Phase 3 trials. No study reported efficacy of biologic medications in pediatric patients, however cyclosporine improved clinical severity by the greatest amount in this group. LIMITATIONS: A lack of well controlled comparison studies make direct comparisons between the treatments difficult. CONCLUSION: For treatment of severe AD, the strongest evidence currently exists for dupilumab and cyclosporine at improving clinical disease severity. Further research is required to determine long term safety and efficacy of biologic medications. PMID- 30296536 TI - Achieving eversion utilizing topical tissue adhesive. PMID- 30296537 TI - Analysis of cutaneous Merkel Cell Carcinoma outcomes after different surgical interventions. AB - BACKGROUND: Current guidelines recommend local excision margin (EM) with 1 to 2cm on primary merkel cell carcinoma (MCC) site. OBJECTIVE: We compared survival outcomes of MCC patients treated with different surgical interventions. METHODS: A retrospective analysis of MCC cases in the SEER database was performed by Kaplan-Meier, competing risk and Cox proportional hazards regression model analyses. Influence of age, T stage, AJCC stage, adjuvant radiotherapy and other subgroups were also analyzed by pair-wise log-rank test. RESULTS: Our results indicated significant association between local destruction method and inferior survival, while EM>2cm showed significantly higher overall survival (OS). In addition, competing risk analysis depicted similar trend as Kaplan-Meier analysis, and considerably reduced estimated cumulative incidence. Further subgroup pair-wise analysis demonstrated that EM>2cm method had better survival in patients younger than 60 years, having smaller tumor diameters (T1 and T2) or undergone adjuvant radiotherapy (p<0.05). In contrast, different EMs did not show any significant association with survival rate in patients older than 75 years or stage III tumors. LIMITATIONS: This study was not prospectively randomized without relapse data. CONCLUSIONS: It is challenging to make optimal EM recommendations, as surgical options may depend on individual case situations. Further prospective randomized studies are warranted.

AB - Within the last two decades, for-profit financial groups have become increasingly involved in health care. Outlier dermatology practices with high volumes of well reimbursed procedures are attractive to consolidation backed by private equity. With fewer choices for independent or group private practice, junior dermatologists are increasingly seeking employment without ownership in private equity-backed corporate groups, whose primary fiscal responsibility lies with investors. Medicare's response to corporatization and consolidation has already changed the practice of dermatopathology. Dermatologists should be aware of this history, given the ability of corporations and private equity groups to shape the present and future of our field. PMID- 30296542 TI - Predictors of mucosal melanoma survival in a population-based setting. AB - BACKGROUND: Mucosal melanomas are rare and aggressive neoplasms, with little published population-based data on predictors of survival. OBJECTIVE: To assess the influences of race/ethnicity, sex, tumor stage, tumor thickness, and anatomic site on mucosal melanoma survival estimates. METHODS: We analyzed 132,751 cases of melanoma, including 1,824 mucosal melanomas, diagnosed between 1994 and 2015 and reported to the California Cancer Registry. Kaplan-Meier survival analysis and Cox proportional hazards regression assessed the prognostic variables. RESULTS: The 5-year relative survival for mucosal melanomas (27.64%, 95% confidence interval [CI] 25.42 - 29.91) was significantly lower than for cutaneous melanomas (76.28%, 95% CI 76.03 - 76.53). Stage independently influenced survival, and thickness did not predict survival for neoplasms of known depth. Less common anatomic sites conferred worse prognoses (hazard ratio [HR] 1.93, 95% CI: 1.41 - 2.64). LIMITATIONS: Lack of a standardized staging system may have resulted in misclassification of stage for some neoplasms. The influence of genetics is unknown because our database did not contain genetic characteristics. CONCLUSIONS: Stage and anatomic site, but not thickness (i.e. Breslow depth), race, or ethnicity, determine prognosis of mucosal melanomas. Considering the poor prognosis for all stages of mucosal melanoma, dermatologists should incorporate examination of the oropharynx and genitalia in the full body skin exam. PMID- 30296544 TI - Steroids-specific target library for steroids target prediction. AB - Steroids exist universally and play critical roles in various biological processes. Identifying potential targets of steroids is of great significance in studying their physiological and biochemical activities, the side effects and for drug repurposing. Herein, aiming at more precise steroids targets prediction, a steroids-specific target library integrating 3325 PDB or homology modeling structures categorized into 196 proteins was built by considering chemical similarity from DrugBank and biological processes from KEGG. The main properties of this library include: (1) It was manually prepared and checked to eliminate mistakes. (2) The library enriched the possible steroids targets and could decrease the false positives of structure-based target screening for steroids. (3) The ranking by protein name instead of PDB ID could make the screening more efficiency and precise. (4) Protein flexibility was taken into account partially by the different active conformations through the structural redundancy of each category of protein, which leads to more accurate prediction. The case studies of glycocholic acid and 24-epibrassinolide proved its powerful predictive accuracy. In summary, our strategy to build the steroids-specific protein library for steroids target prediction is a promising approach and it provides a novel idea for the target prediction of small molecules. PMID- 30296543 TI - C21 steroids from Streptocaulon juventas (Lour) Merr. induce apoptosis in HepG2. AB - Three new C21 steroids, i.e., (3beta,17alpha,20S)-pregn-5(6)-ene-3, 17, 20-triol 3-O-beta-d-digitalopyranosyl-(1 -> 4)-beta-d-digitalopyranoside (4), (3beta,17alpha,20S)-pregn-5(6)-ene-3, 17, 20-triol-20-O-beta-d-glucopyranosyl-(1 > 6)-beta-d-glucopyranosyl-(1 -> 2)-beta-d-digital-opyranoside (8), (3beta, 20R) pregn-14(15)-ene-3, 20, 21-triol-3-O-beta-d-glucopy-ranoside (10), along with ten known C21 steroids were isolated from Streptocaulon juventas. Their structures were elucidated on the basis of 1D and 2D NMR spectroscopic techniques, mass spectrometry as well as comparison with the literature. All the isolated compounds were screened for their in vitro cytotoxicity against human liver cancer cells (HepG2) and the structure-activity relationships were also analyzed. Moreover, compounds 1-3, 5, 10-12, which displayed cytotoxic activities in HepG2 cells, were tested for the selective index (SI) by the ratio of cytotoxic effect on human hepatocytes (LO2) to that on HepG2. As a result, new compound 10 exhibited a good inhibitory activity against HepG2 with IC50 value 11.7 MUM as well as high SI value 3.5. Furthermore, compound 10 could induce HepG2 cells apoptosis by flow cytometry. PMID- 30296545 TI - Timosaponin AIII: A novel potential anti-tumor compound from Anemarrhena asphodeloides. AB - Timosaponin AIII, a major steroidal saponin found in Anemarrhena asphodeloides Bge., which has been widely used as anti-pyretic, anti-diabetic, anti inflammatory, anti-platelet aggregator and anti-depressant agents in traditional Chinese medicine. Recent pharmacological study showed that timosaponin AIII had potent cytotoxicity, which was potential to be developed as an anticancer agent, however the molecular mechanism underlying the anticancer activity has not been fully elucidated. This review aims to give a systematic summary of the study of timosaponin AIII to reveal its anti-tumor activities by investigating invasion and migration, apoptosis, autophagy and reversing multi-drug resistance. Furthermore, we also make an overview of the mechanisms identified till now. These meaningful findings may provide novel insights on exploiting timosaponin AIII as a new anti-tumor agent. PMID- 30296546 TI - Pregn-5-en-3beta-ol and androst-5-en-3beta-ol dicarboxylic acid esters as potential therapeutics for NMDA hypofunction: In vitro safety assessment and plasma stability. AB - Neurosteroids are endogenous steroidal compounds that can modulate neuronal receptors. N-Methyl-D-aspartate receptors (NMDARs) are glutamate-gated, calcium permeable ion channels that are of particular interest, as they participate in synaptic transmission and are implicated in various processes, such as learning, memory, or long-term neuronal potentiation. Positive allosteric modulators that increase the activity of NMDARs may provide a therapeutic aid for patients suffering from neuropsychiatric disorders where NMDAR hypofunction is thought to be involved, such as intellectual disability, autism spectrum disorder, or schizophrenia. We recently described a new class of pregn-5-ene and androst-5-ene 3beta-dicarboxylic acid hemiesters (2-24) as potent positive modulators of NMDARs. Considering the recommended guidelines for the early stage development of new, potent compounds, we conducted an in vitro safety assessment and plasma stability screening to evaluate their druglikeness. First, compounds were screened for their hepatotoxicity and mitochondrial toxicity in a HepG2 cell line. Second, toxicity in primary rat postnatal neurons was estimated. Next, the ability of compounds 2-24 to cross a Caco-2 monolayer was also studied. Finally, rat and human plasma stability screening revealed an unforeseen high stability of the C-3 hemiester moiety. In summary, by using potency/efficacy towards NMDARs data along with toxicity profile, Caco-2 permeability and plasma stability, compounds 14 and 15 were selected for further in vivo animal studies. PMID- 30296547 TI - Steroid profiling in nails using liquid chromatography-tandem mass spectrometry. AB - The retrospective analysis of endogenous steroid hormones in nails can be used to elucidate endocrine diseases and thus help with their diagnosis and treatment. A liquid chromatography-tandem mass spectrometry (LC-MS/MS) based method was developed for the simultaneous identification and quantification of 12 steroid hormones (aldosterone, cortisone, cortisol, corticosterone, 11-deoxycortisol, androstenedione, 11-deoxycorticosterone, testosterone, dehydroepiandrosterone (DHEA), 17alpha-hydroxyprogesterone (17-OHP), dihydrotestosterone (DHT) and progesterone) in human fingernails. Steroid hormones were extracted from 0.5 mg to 10 mg pulverized nail clippings by methanolic extraction, followed by a liquid liquid extraction. The analysis was conducted with LC-MS/MS in electrospray ionization positive mode. The method was validated in terms of linearity, limit of detection (LOD), limit of quantification (LOQ), precision, accuracy, matrix effect, recovery and robustness. It was successfully applied for steroid profiling in nails of mothers and their infants where cortisol, cortisone, testosterone, progesterone, androstenedione and 11-deoxycorticosterone could be detected. Furthermore, it could be shown that there is no significant difference in concentrations between left and right hand for cortisol, cortisone and progesterone. A positive linear correlation between cortisol and cortisone in nails was found. In conclusion, it could be shown that nails are a suitable matrix for the retrospective monitoring of cumulative steroid hormone levels. PMID- 30296548 TI - Separation and identification of the epimeric doping agents - Dexamethasone and betamethasone in equine urine and plasma: A reversed phase chiral chromatographic approach. AB - Chirality is one of the most important considerations when controlling doping. The epimeric corticosteroids dexamethasone and betamethasone are significantly potent and long-acting, and they are highly abused in equestrian sports. The scope of this study was to develop a simple and reliable analytical method for simultaneously identifying and separating regularly abused co-eluting corticosteroids in equine urine and plasma. In this paper, we present a simple and rapid method for the chiral separation and identification of epimeric mixtures of dexamethasone and betamethasone using a Thermo Q Exactive high resolution accurate mass spectrometer. The high resolution accurate mass spectrometer system provided extremely high sensitivity, enabling detection of each isomer at a very low concentration from complex biological matrices. Chromatographic separation was performed using amylose and cellulose chiral columns. Reversed phase media showed very good potential for providing a successful chiral resolution in LC-MS analysis. This study also focused on optimizing the mobile phase for elution strength, nature of the organic modifier, additives, and column temperature.

AB - A series of novel fluorine-containing lupane triterpenoid acid derivatives with fluoroaromatic amide moieties at the C-28 position (1-8) or with 2 (fluoroacyl)cyclopentane-1,3-dione fragments at the C-3 position (9-18) of lupane skeleton was synthesized. A simple synthesis of novel lupane triterpenoid hybrids with 2-(fluoroacyl)-2-cyclopenten-1-one moieties was developed. An interaction of 2-acyl-3-chlorocyclopent-2-en-1-ones, obtained from corresponding cyclic beta triketones, with methyl 3-amino-3-deoxybetulinate gave 3beta-isomers (9-13) and 3alpha-isomers (14-18) of target hybrids, which were isolated as individual compounds. Anti-inflammatory properties of selected synthesized compounds were studied in vivo using the histamine-, concanavalin A- and sheep erythrocytes immunization-induced mouse paw edema models. The antioxidant activity was investigated in vivo on the model of tetracycline-induced hepatitis. Majority of synthesized fluorine-containing lupane triterpenoid acid derivatives exhibited significant anti-inflammatory and antioxidant effects. Among studied compounds, 3beta-hybrid 11 with 2-perfluorobutanoyl-2-cyclopenten-1-one moiety was the most potent bioactive compound.

AB - Using pregnenolone as a starting material, some 3-substituted 17-[1',2',3'] selenadiazolylpregnenolone derivatives were synthesized, and their structures were characterized by IR, NMR and HRMS. The in vitro antitumor activity of the compounds was assayed against PC-3,SKOV3,T47D,MCF-7 and HEK293T cell lines. The results show that some compounds display selective antiproliferative activity against PC-3 and SKOV3 cells lines and are almost inactive to normal kidney epithelial cells (HEK293T). The IC50 value are much better than that of abiraterone (positive control). PMID- 30296551 TI - Peptide-based therapeutics: quality specifications, regulatory considerations, and prospects. AB - Exquisite selectivity, remarkable efficacy, and minimal toxicity are key attributes inherently assigned to peptides, resulting in increased research interest from the pharmaceutical industry in peptide-based therapeutics (PbTs). Pharmacopoeias develop authoritative standards for PbT by providing standard specifications and test methods. Nevertheless, a lack of harmonization in test procedures adopted for PbT in the latest editions of Pharmacopoeias has been observed. Adoption of a harmonized monograph could increase further the interest of the global pharmaceutical industry in PbTs. Here, we provide an overview of pharmacopoeial methodologies and specifications commonly observed in PbT monographs and highlight the main differences among the pharmacopoeias in terms of the active pharmaceutical ingredients that they focus on. We also address the prospects for PbTs to mature as a new therapeutic niche. PMID- 30296552 TI - Anti-biofilm efficacy of root canal irrigants against in-situ Enterococcus faecalis biofilms in root canals, isthmuses and dentinal tubules. AB - OBJECTIVE: To investigate the anti-biofilm efficacy of root canal irrigants in canal spaces, isthmi and dentinal tubules of root canals ex vivo. METHODS: Fifty one single-rooted premolars, each containing an isthmus, were instrumented, autoclaved and inoculated with Enterococcus faecalis for 4 weeks. One specimen was sectioned for bacteria-specific staining to confirm the presence of biofilms using light microscopiy. The remaining specimens were randomly divided to five groups: (1) 0.9% NaCl, (2) SilverSol/H2O2, (3) HYBENX, (4) QMix 2 in1, (5) 6% NaOCl. Bacterial sampling was performed before (S1) and after (S2) canal irrigation. Diluted bacteria suspension was cultured for 48 h for counting the colony forming units (CFU). Percentages of dead bacteria and biofilm thickness were evaluated by confocal laser scanning microscopy (CLSM). Metabolic activity, lactic acid and polysaccharide synthesis of E. faecalis derived from S2 samples were analysed. RESULTS: The percentages of dead bacteria were significantly affected by the factor "irrigant" (p < 0.001) and the factor "location" (p = 0.017). The percentages of dead bacteria in the isthmi and canals were both in the ordor: NaCl < SilverSol/H2O2 < HYBENX < QMix 2 in1 < NaOCl (p < 0.05). Only 6% NaOCl disrupted biofilms and significantly reduced their thickness. The CFU, metabolic activity, polysaccharide and lactic acid production of E. faecalis were all reduced by the disinfecting solutions. CONCLUSIONS: SilverSol/H2O2 and HYBENX were less adept than QMix 2 in1 at killing biofilm bacteria in root canals. None of these antibacterial irrigants were effective, compared with 6% NaOCl, in disrupting biofilms. CLINICAL SIGNIFICANCE: There is advantage in using HYBENX or QMix 2 in1 to kill intratubular bacteria biofilms because of their capability in removing the inorganic component of the smear layer. SilverSol/H2O2 requires extra time to eradicate intratubular biofilms upon removal of the organic and inorganic components of the smear layer by other root canal irrigants. PMID- 30296553 TI - Silver improves collagen structure and stability at demineralized dentin: A dynamic-mechanical and Raman analysis. AB - OBJECTIVE: This study aimed to evaluate the effect of silver loaded nanoparticles (NPs) application on dentin remineralization. METHODS: Polymethylmetacrylate based NPs and silver loaded NPs (Ag-NPs) were applied on demineralized dentin surfaces. Dentin was characterized morphologically by scanning electron microscopy, mechanically probed by a nanoindenter to test nanohardness and Young modulus, and chemically analyzed by Raman spectroscopy after 24 h and 7 d of storage. Untreated surfaces were used as control. Data were submitted to ANOVA and Student-Newman-Keuls multiple comparisons tests (P < 0.05). RESULTS: After Raman analysis, dentin treated with Ag-NPs obtained the lowest mineralization and intensity of stoichiometric hydroxyapatite when compared with specimens treated with undoped-NPs. The lowest relative mineral concentration, expressed as the ratio phosphate or carbonate/phenyl group, and crystallinity was attained by dentin treated with Ag-NPs, after 7 d. Ag-NPs application generated the highest values of collagen crosslinking (intensity at 1032 cm-1 band). The molecular conformation of the collagen's polypeptide chains, amide-I and CH2 also attained the highest peaks in dentin treated with Ag-NPs. Staggered and demineralized collagen fibrils were observed covering the dentin surfaces treated with Ag-NPs, at both 24 h and 7 d. Samples treated with Ag-NPs attained the lowest values of nanohardness and Young's modulus at 7 d of storage. CONCLUSIONS: Peritubular and intertubular dentin were remineralized when using undoped-NPs. After 7 d, collagen treated with NPs was remineralized but dentin treated with Ag-NPs attained an improved collagen matrix structure and stability but the lowest mineralization and crystallinity. CLINICAL SIGNIFICANCE: Preservation of the demineralized organic matrix is fundamental in operative dentistry. Silver contributed to improve crosslinking, nature and secondary structure of demineralized dentin collagen, for further long-term intrafibrillar mineralization. PMID- 30296554 TI - Imaging glutamate redistribution after acute N-acetylcysteine administration: A simultaneous PET/MR study. AB - Glutamate is the most abundant excitatory neurotransmitter in the human brain, but in vivo imaging of acute fluctuations in glutamatergic levels has not been well established. The purpose of this study was to examine acute changes in glutamate after stimulation with N-acetylcysteine (NAC) using a simultaneous positron emission tomography/magnetic resonance spectroscopy (PET/MRS) approach. Ten healthy adult males were examined in two scanning sessions, and 5g NAC was administered 1 h prior to one of the scan sessions. Simultaneous PET/MR data were acquired using an integrated 3T PET/MR scanner. Glutamate (Glu), glutamine (Gln), and glutamate + glutamine (Glx) levels were assessed from MRS data collected from the basal ganglia with PRESS and from the left prefrontal cortex with PRESS and MEGAPRESS, and mGluR5 binding (BPND) was assessed from PET data collected with [18F]PSS232. NAC administration was associated with a significant reduction in Glx and Gln in the basal ganglia spectra, and in Glx in the frontal MEGAPRESS spectra (p < 0.05); no differences in [18F]PSS232 BPND were observed with NAC, although a correlation between pre-/post-treatment Glx and baseline BPnd was found. The MRS-visible Glx signal is sensitive to acute fluctuations in glutamate. The change in Glx was mostly driven by a change in Gln, lending weight to the notion that Gln can provide a proxy marker for neurotransmitter/synaptic glutamate. [18F]PSS232 binding is not sensitive to acute glutamate shifts independently, but was associated with the extent of glutamate liberation upon NAC stimulation. PMID- 30296555 TI - Predominantly global genetic influences on individual white matter tract microstructure. AB - Individual differences in white matter tract microstructure, measured with diffusion tensor imaging (DTI), demonstrate substantial heritability. However, it is unclear to what extent this heritability reflects global genetic influences or tract-specific genetic influences. The goal of the current study was to quantify the proportion of genetic and environmental variance in white matter tracts attributable to global versus tract-specific influences. We assessed fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) across 11 tracts and 22 subdivisions of these tracts in 392 middle-aged male twins from the Vietnam Era Twin Study of Aging (VETSA). In principal component analyses of the 11 white matter tracts, the first component, which represents the global signal, explained 50.1% and 62.5% of the variance in FA and MD, respectively. Similarly, the first principal component of the 22 tract subdivisions explained 38.4% and 47.0% of the variance in FA and MD, respectively. Twin modeling revealed that DTI measures of all tracts and subdivisions were heritable, and that genetic influences on global FA and MD accounted for approximately half of the heritability in the tracts or tract subdivisions. Similar results were observed for the AD and RD diffusion metrics. These findings underscore the importance of controlling for DTI global signals when measuring associations between specific tracts and outcomes such as cognitive ability, neurological and psychiatric disorders, and brain aging. PMID- 30296556 TI - Ventral striatum links motivational and motor networks during operant-conditioned movement in rats. AB - Voluntary actions require motives. It is already known that the medial prefrontal cortex (MPFC) assess the motivational values. However, it remains unclear how the motivational process gains access to the motor execution system in the brain. Here we present evidence that the ventral striatum (VS) plays a hub-like role in mediating motivational and motor processing in operant behavior. We used positron emission tomography (PET) to detect the neural activation areas associated with motivational action. Using obtained regions, partial correlation analysis was performed to examine how the motivational signals propagate to the motor system. The results revealed that VS activity propagated to both MPFC and primary motor cortex through the thalamus. Moreover, muscimol injection into the VS suppressed the motivational behavior, supporting the idea of representations of motivational signals in VS that trigger motivational behavior. These results suggest that the VS-thalamic pathway plays a pivotal role for both motivational processing through interactions with the MPFC and for motor processing through interactions with the motor BG circuits. PMID- 30296558 TI - Sex difference in brain CB1 receptor availability in man. AB - The endocannabinoid system (ECS) has a widespread neuromodulatory function in the central nervous system and is involved in important aspects of brain function including brain development, cortical rhythms, plasticity, reward, and stress sensitivity. Many of these effects are mediated via the cannabinoid CB1 receptor (CB1R) subtype. Animal studies convincingly show an interaction between the ECS and sex hormones, as well as a sex difference of higher brain CB1R in males. Human in vivo studies of sex difference have yielded discrepant findings. Gender differences in CB1R availability were investigated in vivo in 11 male and 11 female healthy volunteers using a specific CB1R tracer [18F]FMPEP-d2 and positron emission tomography (PET). Regional [18F]FMPEP-d2 distribution volume was used as a proxy for CB1R availability. In addition, we explored whether CB1R availability is linked to neuropsychological functioning. Relative to females, CB1R availability was on average 41% higher in males (p = 0.002) with a regionally specific effect larger in the posterior cingulate and retrosplenial cortices (p = 0.001). Inter-subject variability in CB1R availability was similar in both groups. Voxel-based analyses revealed an inverse association between CB1R availability and visuospatial working memory task performance in both groups (p < 0.001). A CB1R sex difference with a large effect size was observed and should be considered in the design of CB1R-related studies on neuropsychiatric disorders. The behavioural correlates and clinical significance of this difference remain to be further elucidated, but our studies suggest an association between CB1R availability and working memory. PMID- 30296557 TI - A neural mechanism of direct and observational conditioning for placebo and nocebo responses. AB - Classical theories suggest placebo analgesia and nocebo hyperalgesia are based on expectation and conditioned experience. Whereas the neural mechanism of how expectation modulates placebo and nocebo effects during pain anticipation have been extensively studied, little is known about how experience may change brain networks to produce placebo and nocebo responses. We investigated the neural pathways of direct and observational conditioning for conscious and nonconscious conditioned placebo/nocebo effects using magnetoencephalography and a face visual cue conditioning model. We found that both direct and observational conditioning produced conscious conditioned placebo and nocebo effects and a nonconscious conditioned nocebo effect. Alpha band brain connectivity changes before and after conditioning could predict the magnitude of conditioned placebo and nocebo effects. Particularly, the connectivity between the rostral anterior cingulate cortex and middle temporal gyrus was an important indicator for the manipulation of placebo and nocebo effects. Our study suggests that conditioning can mediate our pain experience by encoding experience and modulating brain networks. PMID- 30296559 TI - Time ambiguity during intertemporal decision-making is aversive, impacting choice and neural value coding. AB - We are often presented with choices that differ in their more immediate versus future consequences. Interestingly, in everyday-life, ambiguity about the exact timing of such consequences frequently occurs, yet it remains unknown whether and how time-ambiguity influences decisions and their underlying neural correlates. We developed a novel intertemporal fMRI choice task in which participants make choices between sooner-smaller (SS) versus later-larger (LL) monetary rewards with systematically varying levels of time-ambiguity. Across trials, delay information of the SS, the LL, or both rewards was either exact (e.g., in 5 weeks), of low ambiguity (4 week range: e.g., in 3-7 weeks), or of high ambiguity (8 week range: e.g., in 1-9 weeks). Choice behavior showed that the majority of participants preferred options with exact delays over those with ambiguous delays, indicating time-ambiguity aversion. Consistent with these results, the ventromedial prefrontal cortex showed decreased activation during ambiguous versus exact trials. In contrast, intraparietal sulcus activation increased during ambiguous versus exact trials. Furthermore, exploratory analyses suggest that more time-ambiguity averse participants show more insula and dorsolateral prefrontal cortex activation during subjective value (SV)-coding of ambiguous versus exact trials. Lastly, the best-fitting computational choice models indicate that ambiguity impacts the SV of options via time perception or via an additive ambiguity-related penalty term. Together, these results provide the first behavioral and neural signatures of time-ambiguity, pointing towards a unique profile that is distinct from impatience. Since time-ambiguity is ubiquitous in real-life, it likely contributes to shortsighted decisions above and beyond delay-discounting. PMID- 30296560 TI - Advanced Hadamard-encoded editing of seven low-concentration brain metabolites: Principles of HERCULES. AB - PURPOSE: To demonstrate the framework of a novel Hadamard-encoded spectral editing approach for simultaneously detecting multiple low-concentration brain metabolites in vivo at 3T. METHODS: HERCULES (Hadamard Editing Resolves Chemicals Using Linear-combination Estimation of Spectra) is a four-step Hadamard-encoded editing scheme. 20-ms editing pulses are applied at: (A) 4.58 and 1.9 ppm; (B) 4.18 and 1.9 ppm; (C) 4.58 ppm; and (D) 4.18 ppm. Edited signals from gamma aminobutyric acid (GABA), glutathione (GSH), ascorbate (Asc), N-acetylaspartate (NAA), N-acetylaspartylglutamate (NAAG), aspartate (Asp), lactate (Lac), and likely 2-hydroxyglutarate (2-HG) are separated with reduced signal overlap into distinct Hadamard combinations: (A+B+C+D); (A+B-C-D); and (A-B+C-D). HERCULES uses a novel multiplexed linear-combination modeling approach, fitting all three Hadamard combinations at the same time, maximizing the amount of information used for model parameter estimation, in order to quantify the levels of these compounds. Fitting also allows estimation of the levels of total choline (tCho), myo-inositol (Ins), glutamate (Glu), and glutamine (Gln). Quantitative HERCULES results were compared between two grey- and white-matter-rich brain regions (11 min acquisition time each) in 10 healthy volunteers. Coefficients of variation (CV) of quantified measurements from the HERCULES fitting approach were compared against those from a single-spectrum fitting approach, and against estimates from short-TE PRESS data. RESULTS: HERCULES successfully segregates overlapping resonances into separate Hadamard combinations, allowing for the estimation of levels of seven coupled metabolites that would usually require a single 11-min editing experiment each. Metabolite levels and CVs agree well with published values. CVs of quantified measurements from the multiplexed HERCULES fitting approach outperform single-spectrum fitting and short-TE PRESS for most of the edited metabolites, performing only slightly to moderately worse than the fitting method that gives the lowest CVs for tCho, NAA, NAAG, and Asp. CONCLUSION: HERCULES is a new experimental approach with the potential for simultaneous editing and multiplexed fitting of up to seven coupled low-concentration and six high-concentration metabolites within a single 11-min acquisition at 3T. PMID- 30296561 TI - Probabilistic TFCE: A generalized combination of cluster size and voxel intensity to increase statistical power. AB - The threshold-free cluster enhancement (TFCE) approach integrates cluster information into voxel-wise statistical inference to enhance detectability of neuroimaging signal. Despite the significantly increased sensitivity, the application of TFCE is limited by several factors: (i) generalisation to data structures, like brain network connectivity data is not trivial, (ii) TFCE values are in an arbitrary unit, therefore, P-values can only be obtained by a computationally demanding permutation-test. Here, we introduce a probabilistic approach for TFCE (pTFCE), that gives a simple general framework for topology based belief boosting. The core of pTFCE is a conditional probability, calculated based on Bayes' rule, from the probability of voxel intensity and the threshold wise likelihood function of the measured cluster size. In this paper, we provide an estimation of these distributions based on Gaussian Random Field theory. The conditional probabilities are then aggregated across cluster-forming thresholds by a novel incremental aggregation method. pTFCE is validated on simulated and real fMRI data. The results suggest that pTFCE is more robust to various ground truth shapes and provides a stricter control over cluster "leaking" than TFCE and, in many realistic cases, further improves its sensitivity. Correction for multiple comparisons can be trivially performed on the enhanced P-values, without the need for permutation testing, thus pTFCE is well-suitable for the improvement of statistical inference in any neuroimaging workflow. Implementation of pTFCE is available at https://spisakt.github.io/pTFCE. PMID- 30296562 TI - Pattern-sensitive neurons reveal encoding of complex auditory regularities in the rat inferior colliculus. AB - A 'pattern alternation paradigm' has been previously used in human ERP recordings to investigate the brain encoding of complex auditory regularities, but prior studies on regularity encoding in animal models to examine mechanisms of adaptation of auditory neuronal responses have used primarily oddball stimulus sequences to study stimulus-specific adaptation alone. In order to examine the sensitivity of neuronal adaptation to expected and unexpected events embedded in a complex sound sequence, we used a similar patterned sequence of sounds. We recorded single unit activity and compared neuronal responses in the rat inferior colliculus (IC) to sound stimuli conforming to pattern alternation regularity with those to stimuli in which occasional sound repetitions violated that alternation. Results show that some neurons in the rat inferior colliculus are sensitive to the history of patterned stimulation and to violations of patterned regularity, demonstrating that there is a population of subcortical neurons, located as early as the level of the midbrain, that can detect more complex stimulus regularities than previously supposed and that are as sensitive to complex statistics as some neurons in primary auditory cortex. Our findings indicate that these pattern-sensitive neurons can extract temporal and spectral regularities between successive acoustic stimuli. This is important because the extraction of regularities from the sound sequences will result in the development of expectancies for future sounds and hence, the present results are compatible with predictive coding models. Our results demonstrate that some collicular neurons, located as early as in the midbrain level, are involved in the generation and shaping of prediction errors in ways not previously considered and thus, the present findings challenge the prevailing view that perceptual organization of sound only emerges at the auditory cortex level. PMID- 30296563 TI - Machine learning in neuroimaging: Progress and challenges. PMID- 30296564 TI - TCF21 inhibits proliferation and chemoresistance through the AKT pathway in human gastric cancer. AB - In a previous study, we showed that transcription factor 21 (TCF21) is methylated and downregulated in human gastric cancer samples and serves as an independent prognostic factor. However, its biological role and potential mechanism in gastric cancer cells remain unexplored. In the current study, we examined TCF21 expression in 6 gastric cancer cell lines. The BGC-823 and SGC-7901 cell lines were selected for small interfering RNA and plasmid transfection, respectively. The results of the Cell Counting Kit-8 assay demonstrated that TCF21 inhibited gastric cancer cell proliferation. Cell cycle analysis suggested that TCF21 inhibited cell cycle progression in gastric cancer cells. The Matrigel invasion assay demonstrated that TCF21 negatively regulated invasion. The cell adhesion assay showed that TCF21 increased cell adhesion. Gastric cancer cells were treated with cisplatin to explore the role of TCF21 in chemoresistance. Cell Counting Kit-8 assay and AnnexinV/propidium iodide analyses showed that TCF21 overexpression sensitized SGC-7901 cells to cisplatin, whereas its depletion reduced sensitivity in BGC-823 cells. JC-1 staining was performed to measure the effect of TCF21 on mitochondrial potential. TCF21 downregulated mitochondrial membrane potential after treatment with cisplatin. Western blot analysis showed that TCF21 overexpression negatively regulated Bcl-xL, phosphorylated extracellular signal regulated kinase, and phosphorylated AKT expression and induced caspase 3 cleavage. LY294002, an AKT inhibitor, blocked the effect of TCF21 on Bcl-xL, caspase 3 and CDDP-induced apoptosis. Nude mice experiments demonstrated that TCF21 inhibited gastric cancer growth in vivo. In conclusion, our results suggest that TCF21 inhibits gastric cancer growth and chemoresistance possibly through the AKT signaling pathway. PMID- 30296565 TI - Evolutionary distribution of deoxynucleoside 5-monophosphate N-glycosidase, DNPH1. AB - Deoxynucleoside 5-monophosphate N-glycosidase, DNPH1 is a member of the nucleoside 2-deoxyribosyltransferase (NDT) family. This enzyme catalyzes the hydrolysis of deoxynucleoside monophosphates into free nucleobase moieties and 2 deoxyribose 5-phosphates. The DNPH1 enzymatic activity was first demonstrated in rats and then in humans. Subsequently the DNPH1 gene was identified in a variety of organisms, mainly in Metazoa. Herein, we demonstrate that despite DNPH1 genes being distributed in almost all metazoans, the occurrence of DNPH1genes is mosaic. For example, they cannot be found anywhere in the entire clade of Sauropsida or anywhere in the whole phyla of Arthropoda and Ctenophora. Even among mammals, there are organisms without functional DNPH1 protein (Camelidae and most likely Cetacea). By our knowledge, the DNPH1 gene is missing in plants, fungi and in majority of protists. Accordingly, the enzyme is apparently not of vital importance in all the branches of the Tree of Life. Surprisingly the DNPH1 gene may be found in archaea as well as in bacteria. This refers to the origin of the gene from the period before the archaea branched off from other bacteria. We show that the genomic and protein primary structures of DNPH1 are highly conserved and any modification in such a structure would result in conversion to a pseudogene, which could possibly be eliminated from the genome. PMID- 30296567 TI - Chicken GHR antisense transcript regulates its sense transcript in hepatocytes. AB - An increasing number of evidences indicated that long noncoding RNAs (LncRNAs) regulate a variety of biological progresses via different mechanisms. Our previous study had identified a chicken growth hormone receptor (GHR) antisense transcript (GHR-AS) which regulated GHR sense transcript (GHR-S) in LMH cells. In the present study, roles of GHR-AS and its regulatory mechanism were analyzed in chicken hepatocytes. The expression patterns of liver GHR-S, GHR-AS and Let-7b ascended with the development of chicken. The hepatocytes proliferation was promoted and more cells entered into DNA synthesis (S) phase when GHR-AS was overexpressed while the cell proliferation was slowed and fewer cells were in S phase when GHR-AS was interfered. Meanwhile, the GHR-S increased when we overexpressed GHR-AS while it reduced when GHR-AS was inhibited. The S1 Nuclease protection assay indicated that GHR-S and GHR-AS formed RNA duplex via GHR-S 3' untranslation regon (3'UTR). In hepatocytes or LMH cells, the half-time of GHR-S showed a delayed trend when GHR-AS or GHR-AS 5' untranslation regon (5'UTR) was overexpressed. Furthermore, the level of GHR-S can be decreased by Let-7b mimics whereas it was partially rescued when co-transfected pGHR-AS or pGHR-AS 5'UTR with Let-7b mimics. Based on our findings, GHR-AS affected hepatocytes proliferation and improved GHR-S stability possibly by forming RNA duplex between GHR-S and GHR-AS, competing with Let-7b. PMID- 30296566 TI - Liver kinase B1 induces browning phenotype in 3 T3-L1 adipocytes. AB - Induction of brown adipocytes in white adipose tissue is a promising therapy for combating human obesity and its associated disorders. Liver kinase B1 (LKB1) is a tumor inhibitor and metabolic modulator. Recent data suggest that LKB1 is necessary for adipogenesis, but its role in the browning of white adipocytes remains unknown. The objective of this study was to reveal the effect of LKB1 on browning. In our study, we showed that overexpression of LKB1 in 3 T3-L1 adipocytes up-regulated the expression of brown adipocyte markers, including UCP1, PGC-1alpha, Cidea, and PRDM16, and beige-cell-specific genes, such as CD137 and Tmem26. It was possible that the expression of UCP1 and other beige markers was increased by activation of PPARgamma, resulting in the browning of 3 T3-L1 preadipocytes. The browning effect was abolished by a PPARgamma inhibitor (GW9662). Moreover, these effects were dramatically abrogated by silencing of LKB1. Additionally, LKB1 decreased the expression levels of adipogenesis proteins (C/EBPalpha and SREBP1) and up-regulated lipid catabolism protein, perilipin (PLIN). In summary, the study suggested that LKB1 induces the browning of white adipocytes, in addition to promoting lipid metabolism. Therefore, LKB1 may be a helpful therapeutic candidate for treating obesity. PMID- 30296568 TI - Association of PARK2 promoter polymorphisms and methylation with colorectal cancer in North Indian population. AB - Different diseases have been associated with PARK2/PACRG overlapping promoter polymorphisms (rs2276201 and rs9347683) in the recent past. However association of these polymorphisms with cancer remains elusive till date. Thus in this study we evaluated association between these polymorphisms and colorectal cancer (CRC) incidences among North Indians. Genomic DNA was isolated using venous blood of 400 unrelated subjects (200 CRC cases and 200 healthy controls) of North Indian origin. Both SNPs were genotyped using PCR-RFLP method. Promoter methylation status in tumor DNA was checked using MS-PCR. Statistical analysis was performed using SPSS-17 software. In-silico predictions for transcription factor binding were performed using "PROMO" a freely available online tool. SNP rs2276201 showed statistically significant difference (P = 0.047) among cases and controls while rs9347683 did not (P = 0.113). The TC genotype (OR: 1.855, 95% CI: 1.021-3.369, P = 0.043), CC genotype (OR: 1.617, 95% CI: 1.042-2.510, P = 0.032), TT vs CT+CC genetic model (OR: 1.60, P = 0.0158) and allelic model (OR: 1.3931, 95% CI: 1.0498-1.8485, P = 0.0214) of rs2276201 showed significant risk for CRC. For rs9347683 AC genotype (OR: 1.604, 95% CI: 1.019-2.523, P = 0.041) and AA vs AC+CC genetic model (OR: 1.57, P = 0.039) showed significant risk. Haplotype CC provided significant risk (OR: 1.618, 95% CI: 1.112-2.352, P = 0.011) whereas haplotype TA provided significant protection (OR: 0.732, 95% CI: 0.543-0.987, P = 0.040) against CRC. Promoter methylation was significantly higher in tumor grade III + IV (OR: 2.37, P = 0.019), while PARK2 expression was lower in cancer tissues compared to normal tissue. Here we provide the first report where PARK2 promoter SNP's rs2276201 and rs9347683 are shown to be significantly associated with the risk of CRC development. PMID- 30296569 TI - Association of single-nucleotide polymorphisms of the KEAP1 gene with the risk of various human diseases and its functional impact using in silico analysis. AB - Keap1, Kelch-like erythroid derived Cap 'n' collar homology (ECH) associated protein 1 is a highly redox-sensitive member of the BTB-Kelch substrate adaptor protein which acts as a major upstream regulator of Nrf2 (Nuclear factor erythroid 2-related factor 2) by Cul3 ubiquitin E3 ligase complex, leading to its proteasomal degradation. Oxidative and electrophilic stresses impair the structural integrity of Keap1-Cul3 ubiquitin E3 ligase complex resulting in the dissociation of Nrf2-Keap1 binding and nuclear accumulation of Nrf2. Studies on tissue-specific Keap1 null mutation have demonstrated the important roles of Keap1 mediated Nrf2 degradation. An increasing body of evidence suggests that loss of functional mutation in Keap1 arbitrates constitutive activation and expression of Nrf2 which in turn provokes the chemotherapeutic resistance in various diseases. The current review addresses the genetic aspects of KEAP1 including somatic mutations and in silico functional profiling of human disease associated and polymorphic amino acid substitutions. PMID- 30296570 TI - Is there life in the meconium? A challenging, burning question. PMID- 30296571 TI - Nitrogen excretion during marsupial development in the terrestrial isopod Armadillidium vulgare. AB - Marsupial embryos of Armadillidium vulgare (Isopoda: Oniscidea) were collected at different stages of development and assayed for products of nitrogen excretion. Stages were classified as early stage one, late stage one (clear embryo and somite differentiation), early stage two (chorion shed, prior to blastokinesis), late stage two (following blastokinesis), and mancae (vitelline membrane shed; second embryonic molt). Stage one and stage two embryos were primarily ammonotelic. Mancae showed a significant increase in stored uric acid and decrease in ammonia production, in most cases to undetectable levels. The increased metabolic rate of mancae, and the fact that they imbibe marsupial fluid prior to exiting the marsupium, may have favored a switch from ammonotely to uricotely to avoid ammonia toxicity. Protein metabolism, estimated from ammonia production, accounted for 7% of the measured catabolic rate in Stage 2 embryos. Newly emerged juveniles showed a >2-fold increase in metabolism relative to mancae, accompanying the transition from aquatic to aerial respiration. Following 48 h post-emergence, juveniles resumed ammonia excretion, volatilizing the base (NH3) as in later instars. Elevated ammonia excretion in early juveniles may derive from the catabolism of remaining yolk protein. A sharp increase in whole animal glutamine in juveniles is consistent with its role as an intermediary nitrogen store during periodic ammonia excretion. Total ammonia concentration in the marsupial fluid fluctuated but did not increase significantly over time and ammonia was not volatilized across the oostegites, indicating that embryo ammonia is transported into the maternal hemolymph for excretion. PMID- 30296572 TI - Development of a safety and efficacy nanoemulsion delivery system encapsulated gambogic acid for acute myeloid leukemia in vitro and in vivo. AB - This study aimed to improve the solubility, reduce the side effects and enhance the efficacy of gambogic acid against acute myeloid leukemia in vitro and in vivo. This oil-in-water nanoemulsion (average size 17.20 +/- 0.11 nm, zeta potential 4.17 +/- 0.82 mV) containing Tween-80, glycol, squalene and gambogic acid with improving 4000 times solubility was prepared by pseudoternary phase diagrams. We found that this nanoemulsion successfully encapsulated gambogic acid; it was stable and showed an obvious delayed release effect for the drug in three different phosphate-buffered saline (pH = 2.0, 5.8 and 7.4). The half inhibiting concentration (IC50) of this nanoemulsion (480.7 MUg/mL and 408 MUg/mL) were 1.67 times and 1.98 times higher than those of its water solution (287 MUg/mL and 206 MUg/mL) after acting on the toxicity standard cell line (L929 line) for 24 h and 48 h, respectively. Importantly, acute injection toxicity indicated that the half lethal dose (LD50) of this nanoemulsion (23.25 mg/kg, 95% LD50, 21.7-25.16 mg/kg) was 1.26 times higher than that of its water solution (18.59 mg/kg, 95% LD50, 16.84-20.53 mg/kg). Compared with its suspension, the bioavailability of this nanoemulsion was 318.2%. Furthermore, this nanoemulsion had a better efficacy against the acute myeloid leukemia in vitro and in vivo by improving the time and percent of survival (MV4-11 engrafts mice) and reducing half inhibiting concentration values in acute myeloid leukemia such as Jurket, HL 60 and MV4-11 cells. Our studies suggested that this nanoemulsion may be a promising therapeutic medicine for acute myeloid leukemia. PMID- 30296574 TI - Evaluating the frequency of operational research conducted during the 2014-2016 West Africa Ebola epidemic. AB - INTRODUCTION: The West Africa Ebola epidemic of 2014-2016 was the largest Ebola outbreak on record, and thousands of individuals were involved in the response, including local and national governments, as well as numerous philanthropic and other non-governmental organizations. A number of after-action reports and other reviews of the global response to the epidemic routinely pointed out key challenges, including gaps in operational research. METHODS: To determine the extent to which operational research studies were conducted during the 2014-2016 West Africa Ebola epidemic, a quantitative analysis of the literature published during and immediately after the epidemic was conducted. The goal was to identify the proportion of all Ebola-related publications released regarding the epidemic that addressed operational aspects of the response. It was also sought to describe, at a general level, the sorts of studies that were published during the epidemic, with the goal of increasing understanding of whether additional efforts are needed to encourage the conduct and dissemination of operational studies during future public health crises. RESULTS: Among the 3681 publications on Ebola published between the World Health Organization announcement of the Ebola outbreak in March 2014 and the end of 2017, 109 (3%) were determined to be operational research publications. Among these, 64 (58%) were published after the World Health Organization initially declared the outbreak over on January 14, 2016, reflecting the time delay of sharing operational lessons with the broader preparedness and response community. DISCUSSION: Improved sharing of firsthand, operational knowledge from practitioners who respond to outbreaks is critical for improving preparedness activities and informing the development of sound, effective policies that support ongoing and future preparedness efforts. Based on the results from this review, we propose several policy and programmatic innovations that could facilitate knowledge sharing during future outbreaks. PMID- 30296573 TI - Investigation of the risk factors associated with the failure of hepatitis B vaccination of neonates in Yunnan province, China. AB - OBJECTIVE: This study aimed to investigate HBsAg positive rates and risk factors of HBV infection among the children less than 15 years old in Yunnan province, a remote southwest part of mainland China. METHODS: Multi-stage sampling was used to randomly select study subjects from 9,360,000 individuals. Hepatitis B vaccine inoculation rate and HBsAg positive rate were investigated, and then propensity score and generalized linear mixed model (GLMMs) were applied to the case-control study. RESULTS: The average HBsAg positive rate was 1.81%, with 1.2% in urban areas and 2.4% in rural areas. Rate of first-dose-in-time in urban areas was 77.7%, obviously higher than 49.5% in rural areas (chi2=2811.71, P<0.01). Similarly, 3-dose completion coverage rate in urban areas was 93.7%, also higher than 79.0% in rural areas (chi2=1561.43, P<0.01). Maternal HBeAg positivity and HBsAg positivity were proved to be the main risk factors of children with HBV infection. Moreover, paternal HBeAg positivity, paternal HBsAg positivity, the absence and unknown status of HBV vaccine inoculation were risk factors of children with HBV infection as well. CONCLUSION: It was very important to improve the HBV vaccine inoculation rates. Delivering babies in hospital and timely inoculation with HBV vaccine were efficient ways to prevent HBV vertical transmission. PMID- 30296575 TI - Postoperative complications in adult spinal deformity patients with a mental illness undergoing reconstructive thoracic or thoracolumbar spine surgery. AB - BACKGROUND CONTEXT: Previous studies have found an association between mental illness and poor outcomes in spine surgery, but little is known about the effects of depression and/or anxiety on the adult spinal deformity population. In addition, most relevant studies exclusively focused on the lumbar spine and had relatively small patient sizes. PURPOSE: The aim of this study was to investigate whether adult spinal deformity patients with depression and/or anxiety have an increased risk of postoperative complications and reoperation following posterior thoracolumbar spinal surgery. STUDY DESIGN/SETTING: Retrospective database study. METHODS: Adult patients (over 18 years of age) with a diagnosis of spinal deformity undergoing any reconstructive thoracic or thoracolumbar spinal procedure with a posterior approach between 2007 and 2015 Q2 were identified using Current Procedural Terminology codes to query the Pearl Diver patient record database (Pearl Diver Technologies, West Conshohocken, PA, USA). The database includes records of approximately 18 million patients across the United States having Humana insurance. Further selection of patients with depression and/or anxiety and their associated postoperative complications were identified using ICD-9 and ICD-10 diagnosis codes (International Classification of Diseases 9th-10th edition). The mental illness cohort was matched to a control group according to age, sex, and Charlson Comorbidity Index. Patient data was analyzed for reoperation rates and incidence of common postoperative complications. RESULTS: Multilevel posterolateral fusion was the most common included posterior thoracic reconstructive surgery. The mental illness cohort (n = 327) had significantly increased rates of infection (odds ratio [OR] = 1.743, p = .022) and respiratory complications (OR = 1.492, p = .02) at the 90-day postoperative period. The rates of incision and drainage (OR = 1.379, p = .475) and pneumonia (OR = 1.22, p = .573) were increased in the mental illness cohort at the 90-day postoperative period, but not significantly. There were no significant differences in complication and reoperation rates at 1-year postoperatively. CONCLUSIONS: Patients with spinal deformity and pre-existing depression and/or anxiety treated with a posterior thoracolumbar reconstructive spinal surgery had significantly elevated risk of postoperative infections and respiratory complications when compared with the control group. PMID- 30296576 TI - Patient-reported outcomes unbiased by length of follow-up after lumbar degenerative spine surgery: Do we need 2 years of follow-up? AB - BACKGROUND: In modern clinical research, the accepted minimum follow-up for patient-reported outcome measures (PROMs) after lumbar spine surgery is 24 months, particularly after fusion. Recently, this minimum requirement has been called into question. PURPOSE: We aim to quantify the concordance of 1- and 2 year PROMs to evaluate the importance of long-term follow-up after elective lumbar spine surgery. STUDY DESIGN: Retrospective analysis of data from a prospective registry. PATIENT SAMPLE: We identified all patients in our prospective institutional registry who underwent degenerative lumbar spine surgery with complete baseline, 12-month, and 24-month follow-up for ODI and numeric rating scales for back and leg pain (NRS-BP and NRS-LP). OUTCOME MEASURES: Oswestry Disability Index (ODI) and NRS-BP and NRS-LP at 1 year and at 2 years. METHODS: We evaluated concordance of 1- and 2-year change scores by means of Pearson's product-moment correlation and performed logistic regression to assess if achieving the minimum clinically important difference (MCID) at 12 months predicted 24-month MCID. Odds ratios (OR) and their 95% confidence intervals (CI), as well as model areas-under-the-curve were obtained. RESULTS: A total of 210 patients were included. We observed excellent correlation among 12- and 24-month ODI (r = 0.88), NRS-LP (r = 0.76) and NRS-BP (r = 0.72, all p <.001). Equal results were obtained when stratifying for discectomy, decompression, or fusion. Patients achieving 12-month MCID were likely to achieve 24-month MCID for ODI (OR: 3.3, 95% CI: 2.4-4.1), NRS-LP (OR: 2.99, 95% CI: 2.2 4.2) and NRS-BP (OR: 3.4, 95% CI: 2.7-4.2, all p <.001) with excellent areas under-the-curve values of 0.81, 0.77, and 0.84, respectively. Concordance rates between MCID at both follow-ups were 87.2%, 83.8%, and 84.2%. A post-hoc power analysis demonstrated sufficient statistical power. CONCLUSIONS: Irrespective of the surgical procedure, 12-month PROMs for functional disability and pain severity accurately reflect those at 24 months. In support of previous literature, our results suggest that 12 months of follow-up may be sufficient for evaluating spinal patient care in clinical practice as well as in research. PMID- 30296577 TI - The impact of surgical reduction of high-grade lumbosacral spondylolisthesis on proximal femoral angle and qualityof life. AB - BACKGOUND CONTEXT: Abnormal proximal femoral angle (PFA) was recently found to be associated with deteriorating sagittal balance and quality of life (QoL) in high grade spondylolisthesis (HGS). However, the influence of PFA on the QoL of patients undergoing surgery remains unknown. PURPOSE: This study compares the pre and postoperative measurements of sagittal balance including PFA in patients with lumbosacral HGS after surgery. It also determines if PFA is a radiographic parameter that is associated with QoL in patients undergoing surgery. STUDY DESIGN: Retrospective cohort study. PATIENT SAMPLE: Thirty-three patients (mean age 15.6 +/- 3.0 years) operated for L5-S1 HGS between July 2002 and April 2015. Thirteen had in situ fusion and 20 had reduction to a low-grade slip. OUTCOME MEASURES: The outcome measures included PFA and QoL scores measured from the Scoliosis Research Society SRS-30 QoL questionnaire. METHODS: The minimum follow up was 2 years. PFA and QoL were compared pre- and postoperatively. Statistical analysis used nonparametric Mann-Whitney and Wilcoxon Signed Rank tests, Chi square tests to compare proportions, and bivariate correlations with Spearman's coefficients. RESULTS: A decreasing PFA correlated with less pain (r = -0.56, p = .010), improved function (r = -0.51, p = .022) and better self-image (r = -0.46, p = .044) postreduction. Reduction decreased PFA by 5.1 degrees (p = .002), whereas in situ fusion did not alter PFA significantly. Patients with normal preoperative PFA had similar postoperative QoL regardless of the type of surgery, except for self-image, which improved further with reduction (3.73 +/- 0.49 to 4.26 +/- 0.58, p = .015). Patients with abnormal preoperative PFA tended to have a higher QoL in all domains after reduction. CONCLUSION: Decreasing PFA correlates with less pain, better function and self-image. Reduction of HGS decreases PFA. Reduction also relates to a better postoperative QoL when the preoperative PFA is abnormal. When the preoperative PFA is normal, in situ fusion is equivalent to reduction except for self-image, which is better improved after reduction. PMID- 30296578 TI - Cochlear connexin 30 homomeric and heteromeric channels exhibit distinct assembly mechanisms. AB - Many of the mutations in GJB2 and GJB6, which encode connexins 26 and 30 (Cx26 and Cx30), impair the formation of membrane channels and cause autosomal syndromic and non-syndromic hearing loss. In cochlear non-sensory supporting cells, Cx26 and Cx30 form two types of homomeric and heteromeric gap junctions. The biogenesis processes of these channels occurring in situ remain largely unknown. Here we show that Cx30 homomeric and Cx26/Cx30 heteromeric gap junctions exhibit distinct assembly mechanisms in the cochlea. When expressed as homomeric channels, Cx30 preferentially interacts with beta-actin in the peripheral non junctional membrane region, called perinexus, and strongly relies on the actin network for gap junction plaque assembly. In contrast, we found that Cx26/Cx30 heteromeric gap junction plaques are devoid of perinexus and associated actin network, and resist to actin-depolymerizating drug. This supports that Cx26/Cx30 oligomers could be directly delivered from the interior of the cell to the junctional plaque. Altogether, our data provide a novel insight in homomeric and heteromeric gap junction plaque assembly in the cochlea. PMID- 30296579 TI - Protective effects of isatin and its synthetic derivatives against iron, copper and lead toxicity. AB - INTRODUCTION: While some metals are required for physiological functions in the form of essential trace elements, they can cause toxicity in the excessive concentrations. Chelation therapy was used to reduce the adverse effects of acute and chronic poisoning by metals. Isatin derivatives form complexes with copper ions indicating that they may have protective activity against metal overload. METHOD: In this study, four compounds (isatin and three isatin-derivatives Mj1, TR and Mk1) were evaluated for drug-likeliness. Then their potency inhibiting cell proliferation was determined in HEK293 cell culture assay. Finally, IC50 values for lead, copper, and iron was evaluated in the absence and also the presence of isatin and its derivatives. RESULTS: Isatin and its derivatives used in this study complied with the Lipinski criteria for drug-likeliness. The greatest difference between the IC50 values and the non-toxic dose was obtained for TR and Mj1, respectively. Pretreatment with the Mj1 increased the IC50 values for lead, iron, and copper, by 2.1, 1.7 and 1.7 times, respectively. At non-toxic dose, TR has only increased the IC50 values for lead and copper by 1.4 and 1.3 times without affecting iron cytotoxicity. Mk1 increased the IC50 values for lead, copper, and iron by 1.3, 1.8 and 1.7 times, respectively. CONCLUSIONS: Mj1 is suggested as a lead compound for developing therapeutic agents for lead (Pb) toxicity and Mk1 for copper and iron. PMID- 30296580 TI - Genetic Diversity of Streptococcus pneumoniae in Tunisia. AB - OBJECTIVE: The objective of this study was to explore the genetic diversity of Streptococcus pneumoniae by using antibiotic susceptibility testing, serotyping and multilocus sequence typing (MLST) in a Tunisian pneumology hospital. MATERIALS AND METHODS: We investigated 141 strains of S.pneumoniae isolated between 2009 and 2016 in the Microbiology Laboratory at Pneumology Hospital A. Mami, Tunisia. Antimicrobial susceptibility was tested using the disk diffusion method. The MICs of penicillin G, amoxicillin, and cefotaxime were determined by E-test. Serotyping was inferred from the results of a multiplex PCR method targeting forty serotypes. Sequence types (ST) of S.pneumoniae isolates were determined using MLST technique. RESULTS: Among the 141 S. pneumoniae, 69.5% were resistant to erythromycin. The evaluation of susceptibility to beta-lactams showed that 63.8% of the strains were non-susceptible to penicillin, 34% had decreased susceptibility to amoxicillin, and 15% to cefotaxime. We detected 25 serotypes and 10 isolates that were classified as non-typable. The vaccine coverage was 57%, 60.3% and 75.1% for pneumococcal conjugate vaccine 7 (PCV7), PCV10, and PCV13 serotypes, respectively. Overall, 73 STs were identified in this study including 23 that were described for the first time. The most frequent STs were ST179 (n=17), ST3772 (n=14), ST2918 (n=10), ST4003 (n=5) and were related to serotypes 19F, 19A, 14 and 23F, respectively. We classified 110 strains within 45 STs. Three international antibiotic-resistant clones were found, Denmark14-ST230 (n=22), Spain9V-ST156 (n=22) and Portugal19F-ST177 (n=20). CONCLUSION: This study emphasizes the clonal and international dissemination of antibiotic-resistant clones of S.pneumoniae. Significant differences in genetic variation were documented by MLST, within the various serotypes identified. PMID- 30296581 TI - Plasma and interstitial fluid population pharmacokinetics of vancomycin in critically patients with sepsis. AB - OBJECTIVES: Vancomycin is a commonly prescribed antibiotic in the intensive care unit (ICU). However, there is limited data describing its distribution into the interstitial space fluid (ISF) of tissues. The aim of this study was to describe the plasma and tissue ISF population pharmacokinetics of vancomycin in critically ill patients with sepsis. METHODS: Serial vancomycin blood and ISF samples were collected at pre-specified time intervals in critically ill patients with sepsis. ISF sampling occurred using a subcutaneously inserted microdialysis catheter. Bioanalysis was undertaken using a validated spectrometric assay method. Population pharmacokinetic analysis was performed using Pmetrics(r). RESULTS: Seven patients were recruited and pharmacokinetic data was available for six. The median (IQR) age, weight, Acute Physiological and Chronic Health Evaluation II score, Sequential Organ Failure Assessment score and measured creatinine clearance (CrCL) were 55 (44-67) years, 85 (81-102) kg, 20 (16-29), 5 (4-8), and 90 (83-98) mL/min respectively. Vancomycin pharmacokinetics were best described by a three-compartment linear model. Measured CrCL (on vancomycin clearance) and weight (on volume of distribution of the central compartment, Vc) were the only patient covariates that improved the model fit. The coefficients of variation for the vancomycin rate constants into and out of the peripheral and tissue ISF compartments were also high, ranging from 47% to 134%. CONCLUSIONS: There is significant variability of vancomycin distribution into tissue ISF which we were not able to explain with patient characteristics. PMID- 30296582 TI - First Hospitalization for Heart Failure in Outpatients With Stable Coronary Artery Disease: Determinants, Role of Incident Myocardial Infarction, and Prognosis. AB - BACKGROUND: We lack recent data on the incidence, correlates, and prognosis associated with heart failure (HF) development in patients with stable coronary artery disease (CAD). Here, we analyzed HF development in a contemporary population of outpatients with stable CAD. METHODS AND RESULTS: Of 4184 unselected outpatients with stable CAD (ie, myocardial infarction [MI] and/or coronary revascularization >1 year earlier) included in the multicenter CORONOR registry, we identified 3871 patients with no history of hospitalization for HF at inclusion and followed 3785 (98%) of them for 5 years. During follow-up, 211 patients were hospitalized for HF (5-year cumulative incidence 5.7%) and 163 patients had incident MIs. Independent predictors of hospitalization for HF were older age, lower left ventricular ejection fraction (LVEF), atrial fibrillation, higher body mass index, diabetes mellitus, history of hypertension, angina at inclusion, and multivessel CAD. Most hospitalizations for HF (62.6%) occurred in patients with LVEF >=50% at inclusion, and most (92.4%) were not preceded by an incident MI. Hospitalization for HF was a powerful predictor of mortality (adjusted hazard ratio 5.97, 95% confidence interval 4.55-7.83; P < .0001). After hospitalization for HF, mortality rates were similar in patients with LVEFs >=50% and <50% at hospitalization. CONCLUSIONS: Outpatients with stable CAD were frequently hospitalized for HF, and HF was associated with high mortality. Most HF hospitalizations were associated with preserved LVEF at inclusion and were not preceded by an incident MI. PMID- 30296583 TI - Heart Failure Differentially Modulates the Effects of Ivabradine on the Electrical Activity of the Sinoatrial Node and Pulmonary Veins. AB - BACKGROUND: Ivabradine increases the risk of atrial fibrillation (AF). Heart failure (HF) or sinoatrial node (SAN) dysfunction increases the risk of AF, and pulmonary veins (PVs) play a critical role in the pathophysiology of AF. This study investigated the electrophysiologic effects of ivabradine on SANs and PVs in a rabbit model of HF. METHODS AND RESULTS: Conventional microelectrodes were used to simultaneously record the electrical activities and conduction properties of control and HF rabbit SAN-PV preparations before and after perfusion with ivabradine (0.1, 1, or 10 MUmol/L), either alone or with isoproterenol (1 MUmol/L). HF SANs exhibited a lower beating rate than the control SANs. SAN automaticity exit blocks and SAN-PV conduction blocks were observed in 25% and 50% of samples, respectively, with P < .05 for HF SANs (n = 8) but not for control SANs (n = 6). Delayed afterdepolarization (DAD) was observed in 37.5% of HF PVs but not in control PVs. HF PVs exhibited a faster beating rate and more severe fibrosis than control PVs. Ivabradine reduced the SAN beating rates and increased the occurrences of SAN-PV conduction blocks and PV DADs in control and HF preparations. However, ivabradine induced SAN automaticity exit blocks only in HF preparations. Isoproterenol induced PV burst firing and shifting electrical conduction in control and HF preparations. A combination of isoproterenol and ivabradine (10 MUmol/L) in HF preparations resulted in the highest incidences of PV burst firing and SAN-PV electrical shifting. CONCLUSIONS: HF differentially modulates the effects of ivabradine on the electrical activities of SAN and PVs, which may increase PV arrhythmogenesis and contribute to the risk of AF in HF patients. PMID- 30296584 TI - Biochemical Determinants of Changes in Plasma Volume After Decongestion Therapy for Worsening Heart Failure. AB - BACKGROUND: Optimal vascular volume is required to avoid organ dysfunction during decongestive therapy for worsening heart failure (HF). This study investigated the relation between changes in serum substance(s) and the vascular volume after diuresis in HF patients. METHODS AND RESULTS: Data from 47 patients with HF undergoing conventional diuretic therapy were analyzed. Blood tests included measurements of hemoglobin, hematocrit, and serum albumin/solutes. The relative changes in the plasma volume (%PV) from worsening HF to recovery were determined with the use of the Strauss formula. When divided into 2 groups based on the median %PV, the group with preserved volume (%PV >= -10%, range -10% to 21%; n = 23) exhibited a smaller decrease in body weight (-2.50 +/- 1.98 vs -4.29 +/- 2.60 kg; P = .012) and serum sodium (Na) (-1.57 +/- 3.29 vs -4.13 +/- 4.96 mEq/L; P = .04) and chloride (Cl) (-2.0 +/- 4.06 vs -6.79 +/- 5.21 mEq/L; P = .001) concentrations and a smaller increase in albumin (0.20 +/- 0.28 vs 0.41 +/- 0.24g/dL; P = .009) compared with the group with nonpreserved volume (%PV < -11%, range -33% to -11%; n = 24) after decongestive therapy. Changes in %PV were positively correlated with changes in body weight (r = 0.406; P = .0047) and serum Na (r = 0.433; P = .0024) and Cl (r = 0.408; P = .0044) concentrations and negatively correlated with changes in albumin (r = -0.492; P = .0004), blood urea nitrogen (r = -0.306; P = .037), and creatinine (r = -0.306; P = .036). Multivariate logistic regression analysis demonstrated an independent association between preserved %PV and an increased or preserved serum Cl concentration after decongestive therapy (odds ratio 8.71, 95% confidence interval 1.20-63.0; P = .032). CONCLUSIONS: Positive and independent association exists between change in the vascular volume and the serum Cl concentration under decongestive HF therapy. PMID- 30296586 TI - Laboratory trend in vitamin D status in Ireland: Dual concerns about low and high 25OHD. AB - Serum 25-hydroxyvitamin D (25OHD) is the pre-eminent estimate of vitamin D status that we have been measuring in a hospital laboratory setting since the 1970s. We previously evaluated the trend in 25OHD results in our laboratory from 1993 to 2013. Using a time series analysis of monthly average 25OHD results the trend was modelled, and this was used to forecast monthly average 25OHD from 2014 to 2016. In this study, all 25OHD results from 2014 to 2016 were retrieved (n = 67,922) and trimmed to 40,307 results after duplicates were excluded. The average monthly actual 25OHD was almost identical to the average monthly forecast 25OHD (p = 0.028) with a strong correlation between the actual 25OHD and forecast 25OHD (r = 0.69, p < 0.001). This upward trend is attributed to higher oral intake of vitamin D. We have a dual concern: policies to prevent hypovitaminosis D must be offset by strategies to avert hypervitaminosis D. PMID- 30296585 TI - Proteomics analysis reveals that nitric oxide regulates photosynthesis of maize seedlings under water deficiency. AB - Nitric oxide (NO) is an important bioactive molecule that functions in regulating diverse abiotic stresses in plants, whereas its molecular mechanism remains obscure. In this study, treatment with 0.1 mM NO donor (sodium nitroprusside, SNP) significantly alleviated the inhibited growth induced by 15% polyethyleneglycol (PEG)-stimulated water deficiency (WD) for 3 days in maize seedlings, manifested by less decreased plant total fresh weight and dry weight. Comprehensive proteome analysis was further used to measure the expression profiles of leaf proteins of SNP-pretreated maize seedlings under WD conditions to explore the molecular mechanisms of NO-induced WD tolerance. Using 2-DE method, 135 protein spots showed significantly enhanced or reduced abundance, of which 102 spots were successfully identified MALDI-TOF/TOF MS. The identified protein species were associated with diverse functions, and most (52/83, 62.7%) of known protein species were related to photosynthetic processes. Compared to alone PEG treatment, the abundance of 25 identified protein species in SNP + PEG treatment were enhanced among the identified photosynthesis-related protein species. In addition, exogenous SNP application dramatically regulated chlorophyll alpha fluorescence kinetics e.g. the increase of maximum quantum yield of PSII (Fv/Fm), photosynthetic performance index (PI), and IP phase, whereas it remarkably reduced the polyphasic OJIP fluorescence transient, the accumulation of reactive oxygen species (H2O2 and O2*-) and malondialdehyde (MDA). These findings suggest that the NO-induced WD tolerance could be associated with improved photosynthetic capability in higher plants. PMID- 30296587 TI - Vitamin D C3-epimer levels are proportionally higher with oral vitamin D supplementation compared to ultraviolet irradiation of skin in mice but not humans. AB - A proportion of circulating 25-hydroxy vitamin D3 (25(OH)D3)) undergoes epimerization to form C3-epi 25(OH)D3 and C3-epi 1,25(OH)2D3. These epimers have less calcaemic activity than non-epimerized metabolites and are not differentiated by many immunoassays when reporting total 25(OH)D3 levels. This study aimed to compare the effect of exposure to ultraviolet radiation (UVR) and oral vitamin D3 supplementation on vitamin D C3-epimer levels. C57Bl/6 female mice were fed either vitamin D-sufficient (vitamin D3 2000 IU/kg) or -deficient diets (no vitamin D3) for 4 weeks. Among the vitamin D-deficient group, the shaved backs of half were irradiated daily for 4 days with 1 kJ/m2 UVR, followed by twice weekly irradiation for 4 weeks. Despite similar 25(OH)D3 levels, the UV irradiated group had a lower proportion of C3-epi 25(OH)D3 at week 7 (p < 0.05) and week 9 (p < 0.01). C3-epimer concentrations and %C3-epi 25(OH)D3 were also analysed in serum samples from two human clinical trials. These trials investigated the effect of high dose oral vitamin D3 supplementation and narrowband UVB phototherapy, respectively. Serum 25(OH)D3 and the %C3-epi 25(OH)D3 levels measured at 12 months after oral vitamin D3 supplementation were not significantly different to those measured at the time of maximal effect of phototherapy (2 months). Thus, the proportion of 25(OH)D3 that undergoes epimerization is greater with oral vitamin D3 supplementation than exposure to UVR in mice, but not in humans. This important difference between human and murine vitamin D metabolism warrants consideration when interpreting animal studies. PMID- 30296588 TI - Screening for Regulatory Variants in 460 kb Encompassing the CFTR Locus in Cystic Fibrosis Patients. AB - It is estimated that up to 5% of cystic fibrosis transmembrane conductance regulator (CFTR) pathogenic alleles are unidentified. Some of these errors may lie in noncoding regions of the locus and affect gene expression. To identify regulatory element variants in the CFTR locus, SureSelect-targeted enrichment of 460 kb encompassing the gene was optimized to deep sequence genomic DNA from 80 CF patients with an unequivocal clinical diagnosis but only one or no CFTR-coding region pathogenic variants. Bioinformatics tools were used to identify sequence variants and predict their impact, which were then assayed in transient reporter gene luciferase assays. The effect of five variants in the CFTR promoter and four in an intestinal enhancer of the gene were assayed in relevant cell lines. The initial analysis of sequence data revealed previously known CF-causing variants, validating the robustness of the SureSelect design, and showed that 85 of 160 CF alleles were undefined. Of a total 1737 variants revealed across the extended 460 kb CFTR locus, 51 map to known CFTR cis-regulatory elements, and many of these are predicted to alter transcription factor occupancy. Four promoter variants and all those in the intestinal enhancer significantly repress reporter gene activity. These data suggest that CFTR regulatory elements may harbor novel CF disease-causing variants that warrant further investigation, both for genetic screening protocols and functional assays. PMID- 30296589 TI - An Optimized Workflow to Evaluate Estrogen Receptor Gene Mutations in Small Amounts of Cell-Free DNA. AB - The detection of mutated genes in cell-free DNA (cfDNA) in plasma has emerged as an important minimally invasive way to obtain detailed information regarding tumor biology. Reliable determination of circulating tumor-derived DNA, often present at a low quantity amidst an excess of normal DNA in plasma, would be of added value for screening and monitoring of cancer patients and for hypothesis generating studies in valuable retrospective cohorts. Our aim was to establish a workflow to simultaneously assess four hotspot estrogen receptor mutations (mESR1) in cfDNA isolated from only 200 MUL of plasma by means of uniplex or multiplex pre-amplification combined with digital PCR. This workflow was then applied in metastatic breast cancer (MBC) patients receiving systemic therapies for MBC. In accordance with previous studies, estrogen receptor mutations were more frequently detected in endocrine-treated MBC patients at progressive disease [34.1% (15/44)] than before the start of endocrine therapy [3.9% (2/51); P = 0.001]. For a subset of samples, results were compared with analysis of these mutations by Oncomine-targeted next-generation sequencing, which, although requiring a higher cfDNA input, yielded concordant results. The data establish development and validation of a digital PCR workflow for the simultaneous detection of several tumor-derived mutations in minute amounts of cfDNA and show the potential of this workflow for use on archived volume-limited blood samples.

AB - Lupus nephritis (LN) is a common and devastating complication caused by systemic lupus erythematosus. In this study, we evaluated the expression and mechanism of Fos-related antigen 2 (Fra-2) in LN. The results showed that Fra-2 was significantly increased in kidney biopsies of LN patients compared with healthy controls and other kidney disease in glomerular podocytes. The MRL/lpr mouse strain is a murine model of lupus, and it was used to study the mechanisms of Fra 2 in LN. The results showed that Fra-2 was expressed in the glomerular podocytes. We investigated the effects of inflammatory stimuli on Fra-2 protein expression in the glomerular podocytes, and found that interferon gamma was most effective at increasing Fra-2 protein expression. Knockdown of Fra-2 using siRNA enhanced the protein expression of nephrin. Therefore, Fra-2 may be a specific drug target for podocyte injury in LN. PMID- 30296591 TI - Podocyte foot process width is a prediction marker for complete renal response at 6 and 12 months after induction therapy in lupus nephritis. AB - Morphological change that includes diffuse effacement of podocyte foot processes is correlated with proteinuria in patients with lupus nephritis (LN). We collected the data of clinico-pathological parameters and assessed foot process width (FPW) as an index of podocyte effacement in 73 patients with LN who had undergone renal biopsy. The multivariate analysis revealed that female gender (OR: 5.288; 95%CI: 1.197-37.29; p = .0267) and FPW (OR = 0.999, 95%CI = 0.997 0.999, p = .0150) were significantly predictive of a complete renal response (CR) at 6 months, while lymphocyte counts (OR = 1.002; 95%CI = 1.001-1.003, p = .0028) and FPW (OR = 0.998, 95%CI = 0.996-0.999, p = .0027) were significantly predictive of CR at 12 months. The cut-off point determined by the Classification and Regression Trees algorithm showed that FPW <908.3 nm provides the best performance for predicting patients who achieve CR at 12 months. A smaller FPW appears to be a predictive factor for CR at 6 and 12 months after induction therapy. PMID- 30296592 TI - The relationship between autophagy, increased neutrophil extracellular traps formation and endothelial dysfunction in chronic kidney disease. AB - In chronic kidney disease (CKD), the number of circulating neutrophils are increased, and this is usually accompanied by an increased basal activation state. However, the possible association between neutrophil extracellular traps (NETs) with vascular complications has not been evaluated. We assessed the relationship between NETs, autophagy and endothelial dysfunction in maintenance hemodialysis (MHD) patients. NET formation, neutrophil elastase (NE) activities, and serum nucleosome levels were measured in MHD (n = 60) and controls (n = 20). Basal NET formation were markedly increased in MHD patient compared to controls. After PMA stimulation, MHD neutrophils showed significantly increased NETs formation response than controls. The degree of NETs was strongly associated with lower flow-mediated dilatation(%) of brachial artery even after adjustment for cardiovascular risk factors and uremic toxins. Moreover, MHD neutrophils showed increased basal autophagy activity. Interestingly, the levels of NETs were markedly augmented after autophagy inhibition, suggesting a protective role of autophagy in excessive NET formation. PMID- 30296593 TI - A new case confirming and expanding the phenotype spectrum of ADAT3-related intellectual disability syndrome. AB - The present study describes two patients with clinical diagnosis of ID, from a consanguineous family in Israel. Whole exome sequencing identified a homozygous missense mutation in the ADAT3 gene. The clinical features of our patients were compared with several cases described in two recently published studies that documented clinical manifestation of this same mutation. Both affected siblings in our study expressed the previously described clinical features such as intellectual disability, strabismus, FTT/underweight, microcephaly and hypotonia. Interestingly, our patients suffered from additional clinical manifestations that were not detailed in the previous two studies, such as: gait difficulties, instability, teeth abnormalities, neuropathy and contractures of the hand wrist and fingers. We conclude that the ADAT3 gene mutation is responsible for ADAT3 related ID syndrome, which induces the variety clinical manifestations exhibited by our patients. Further studies aimed at identifying and characterizing additional afflicted families worldwide will be required to obtain a more comprehensive understanding of this syndrome. PMID- 30296594 TI - AMPK promotes survival and adipogenesis of ischemia-challenged ADSCs in an autophagy-dependent manner. AB - Some studies have shown that transplanted fat tissues usually cannot survive for long if adipose-derived stem cells (ADSCs) are removed from the tissues in advance. It is more meaningful to explore the mechanism mediating survival and differentiation of ADSCs in the transplanted microenvironment. AMP-activated protein kinase (AMPK) has been shown to be one of the energy receptors that regulate many aspects of cellular metabolism. AMPK activation has been implicated in models of adult ischemic injury, but the mechanism and the regulating effects of AMPK on survival and adipogenesis of transplanted ADSCs are still little known. In this study, we simulated the transplanted microenvironment using oxygen glucose deprivation (OGD) to test the survival and adipogenesis of ADSCs. We found that OGD treatment triggered significant apoptosis and promoted autophagy. Simultaneously, OGD hindered the differentiation of ADSCs into mature adipocytes. After inhibiting AMPK, the OGD-induced apoptosis rate increased but autophagy was inhibited. The adipogenesis level also decreased. To show that the effects of AMPK on apoptosis and adipogenesis were autophagy-dependent, we pre-inhibited or pre-promoted autophagy with siATG7 or rapamycin while blocking AMPK. We found that inhibiting or improving autophagy exacerbated or alleviated the role of AMPK prohibition in apoptosis and adipogenesis. Furthermore, we showed that AMPK inhibition significantly lowered ULK1 activity but promoted mTOR activity, so that to inhibit autophagy. Our study shows that AMPK plays a protective role in maintaining survival and adipogenesis of OGD-challenged ADSCs partly by positively regulating autophagy. AMPK positively regulates autophagy by inhibiting mTOR but promoting ULK1 activity in OGD condition. PMID- 30296595 TI - Early Colonoscopy for Diverticular Bleeding Does Not Reduce Risk of Postdischarge Recurrent Bleeding: A Propensity Score-Matching Analysis. AB - BACKGROUND & AIMS: Colonoscopy within 24 hours (early colonoscopy) is recommended for patients with colonic diverticular bleeding, but it is unclear if this strategy improves postdischarge outcomes. We aimed to determine whether early colonoscopy is associated with decreased risk of rebleeding and hospital re admission within 30 days. METHODS: We performed a retrospective cohort study using Marketscan (Truven Health Analytics, Inc, Ann Arbor, MI), a nationwide insurance claims database. From January 2004 through September 2015, patients with a primary diagnosis of diverticular bleeding who underwent inpatient colonoscopy were included. We used propensity score matching to account for differences between recipients of early vs delayed colonoscopy. Multivariable logistic regression was performed to determine the association between early colonoscopy and rebleeding or hospital re-admission within 30 days of discharge. RESULTS: In total, 20,010 patients underwent colonoscopy for diverticular bleeding; 11,690 underwent early colonoscopy. After propensity matching, 8320 pairs of patients were analyzed. In the matched analysis, higher proportions of patients who received early colonoscopy underwent additional colonoscopies (73%), compared with patients who did not receive early colonoscopy (4%) (P < .0001), but lower proportions received endoscopic interventions (3% vs 8%; P < .0001). On multivariable analysis, early colonoscopy (odds ratio [OR], 1.34; 95% CI, 1.08 1.66; P = .007), transfusion requirement (OR, 2.31; 95% CI, 1.88-2.83; P < .0001), and baseline chronic kidney disease (OR, 2.13; 95% CI, 1.49-3.04; P < .0001) were associated with increased risk of rebleeding within 30 days. Early colonoscopy (OR, 1.18; 95% CI, 1.02-1.36; P = .03), endoscopic intervention (OR, 1.37; 95% CI, 1.03-1.81; P = .03), transfusion requirement (OR, 2.17; 95% CI, 1.88-2.51; P < .0001), coronary artery disease (OR, 1.27; 95% CI, 1.06-1.51; P = .009), and chronic kidney disease (OR, 1.98; 95% CI, 1.54-2.54; P < .0001) were associated with increased re-admission to the hospital within 30 days. CONCLUSIONS: In a propensity-matched analysis, we associated early colonoscopy with increased risk of rebleeding events and hospital re-admissions. However, these observations might be due to confounding factors. PMID- 30296596 TI - Stiffness memory of indirectly 3D-printed elastomer nanohybrid regulates chondrogenesis and osteogenesis of human mesenchymal stem cells. AB - The cellular microenvironment is dynamic, remodeling tissues lifelong. The biomechanical properties of the extracellular matrix (ECM) influence the function and differentiation of stem cells. While conventional artificial matrices or scaffolds for tissue engineering are primarily static models presenting well defined stiffness, they lack the responsive changes required in dynamic physiological settings. Engineering scaffolds with varying elastic moduli is possible, but often lead to stiffening and chemical crosslinking of the molecular structure with limited control over the scaffold architecture. A family of indirectly 3D printed elastomeric nanohybrid scaffolds with thermoresponsive mechanical properties that soften by reverse self-assembling at body temperature have been developed recently. The initial stiffness and subsequent stiffness relaxation of the scaffolds regulated proliferation and differentiation of human bone-marrow derived mesenchymal stem cells (hBM-MSCs) towards the chondrogenic and osteogenic lineages over 4 weeks, as measured by immunohistochemistry, histology, ELISA and qPCR. hBM-MSCs showed enhanced chondrogenic differentiation on softer scaffolds and osteogenic differentiation on stiffer ones, with similar relative expression to that of human femoral head tissue. Overall, stiffness relaxation favored osteogenic activity over chondrogenesis in vitro. PMID- 30296598 TI - Actin Polymerization Mediated by AtFH5 Directs the Polarity Establishment and Vesicle Trafficking for Pollen Germination in Arabidopsis. AB - The process of pollen germination is crucial for flowering plant reproduction, but the mechanisms through which pollen grains establish polarity and select germination sites are not well understood. In this study, we report that a formin family protein, AtFH5, is localized to the vesicles and rotates ahead of Lifeact mEGFP-labeled actin filaments during pollen germination. The translocation of AtFH5 to the plasma membrane initiates the assembly of a collar-like actin structure at the prospective germination site prior to germination. Genetic and pharmacological evidence further revealed an interdependent relationship between the mobility of AtFH5-labeled vesicles and the polymerization of actin filaments: vesicle-localized AtFH5 promotes actin assembly, and the polymerization and elongation of actin filaments, in turn, is essential for the mobility of AtFH5 labeled vesicles in pollen grains. Taken together, our work revealed a molecular mechanism underlying the polarity establishment and vesicle mobility during pollen germination. PMID- 30296597 TI - Association between PPP2CA expression and colorectal cancer prognosis tumor marker prognostic study. AB - BACKGROUND: Colorectal cancer (CRC) is one of the most common cancers worldwide. The aim of this study is to identify candidate genes by bioinformatics and investigate its clinical pathological characters and prognostic significance. METHOD: First, we identify differentially expressed genes (DEGs) in CRC by analyzing gene expression datasets from Gene Expression Omnibus (GEO). Then we performed a bioinformatics analysis by using Oncomine, STRING and Oncolnc databases. Gene Set Enrichment Analysis (GSEA) was performed using TCGA data set. Then, the protein expression level of PPP2CA was detected by immunohistochemistry in 196 pairs of primary colorectal cancer and corresponding non-tumor tissues. RESULT: Total 81 differential expressed genes were identified in the overlap of datasets. PPI network show the hub genes were CCND1, PPP2CA and YAP1. We investigated Oncomine databases and found that PPP2CA mRNA expression was lower in CRC tissues compared with normal tissues. Bioinformatics analysis indicated that PPP2CA expression was associated with epithelial-mesenchymal transition signaling pathway. Low expression of PPP2CA was associated with T stage, N stage, and M stage. Low expression of PPP2CA was associated with worse overall survival for CRC, and retained significance as an independent prognostic factor for CRC. CONCLUSION: PPP2CA may act as an oncogene in the progression of colorectal cancer. Moreover, PPP2CA has potential to be used as prognostic markers or therapeutic targets in CRC. PMID- 30296599 TI - A WW Domain-Containing Protein Forms Immune Nuclear Bodies against Begomoviruses. AB - The bipartite begomoviruses (Geminiviridae family), which are DNA viruses that replicate in the nucleus of infected cells, encode the nuclear shuttle protein (NSP) to facilitate the translocation of viral DNA from the nucleus to the cytoplasm via nuclear pores. This intracellular trafficking of NSP-DNA complexes is accessorized by the NSP-interacting guanosine triphosphatase (NIG) at the cytosolic side. Here, we report the nuclear redistribution of NIG by AtWWP1, a WW domain-containing protein that forms immune nuclear bodies (NBs) against begomoviruses. We demonstrated that AtWWP1 relocates NIG from the cytoplasm to the nucleus where it is confined to AtWWP1-NBs, suggesting that the NIG-AtWWP1 interaction may interfere with the NIG pro-viral function associated with its cytosolic localization. Consistent with this assumption, loss of AtWWP1 function cuased plants more susceptible to begomovirus infection, whereas overexpression of AtWWP1 enhanced plant resistance to begomovirus. Furthermore, we found that a mutant version of AtWWP1 defective for NB formation was no longer capable of interacting with and relocating NIG to the nucleus and lost its immune function against begomovirus. The antiviral function of AtWWP1-NBs, however, could be antagonized by viral infection that induced either the disruption or a decrease in the number of AtWWP1-NBs. Collectively, these results led us to propose that AtWWP1 organizes nuclear structures into nuclear foci, which provide intrinsic immunity against begomovirus infection. PMID- 30296600 TI - Single-Particle Tracking for the Quantification of Membrane Protein Dynamics in Living Plant Cells. AB - The plasma membrane is a sophisticated, organized, and highly heterogeneous structure that compartmentalizes cellular processes. To decipher the biological processes involving membrane proteins, it is necessary to analyze their spatiotemporal dynamics. However, it is difficult to directly assess the dynamics and interactions of biomolecules in living cells using traditional biochemical methods. Single-particle tracking (SPT) methods for imaging and tracking single particles conjugated with fluorescent probes offer an ideal approach to acquire valuable and complementary information about dynamic intracellular processes. SPT can be used to quantitatively monitor the diverse motions of individual particles in living cells. SPT also provides super-spatiotemporal resolution that allows early-stage or rapid response information to be obtained for a better understanding of molecular basis of associated signal transduction processes. More importantly, SPT can be used to detect the motion paths of individual biomolecules in vivo and in situ, thus unveiling the dynamic behavior of the biomolecules that support developmental processes in living cells. In this review, we give an overview of SPT methods, from image acquisition to the detection of single particles, as well as tracking and data analysis. We also discuss recent applications of SPT methods in the field of plant biology to reveal the complex biological functions of membrane proteins. PMID- 30296601 TI - From Golden Rice to aSTARice: Bioengineering Astaxanthin Biosynthesis in Rice Endosperm. AB - Carotenoids are important phytonutrients with antioxidant properties, and are widely used in foods and feedstuffs as supplements. Astaxanthin, a red-colored ketocarotenoid, has strong antioxidant activity and thus can benefit human health. However, astaxanthin is not produced in most higher plants. Here we report the bioengineering of astaxanthin biosynthesis in rice endosperm by introducing four synthetic genes, sZmPSY1, sPaCrtI, sCrBKT, and sHpBHY, which encode the enzymes phytoene synthase, phytoene desaturase, beta-carotene ketolase, and beta-carotene hydroxylase, respectively. Transgneic overexpression of two (sZmPSY1 and sPaCrtI), three (sZmPSY1, sPaCrtI and sCrBKT), and all these four genes driven by rice endosperm-specific promoters established the carotenoid/ketocarotenoid/astaxanthin biosynthetic pathways in the endosperm and thus resulted in various types of germplasm, from the yellow-grained beta carotene-enriched Golden Rice to orange-red-grained Canthaxanthin Rice and Astaxanthin Rice, respectively. Grains of Astaxanthin Rice were enriched with astaxanthin in the endosperm and had higher antioxidant activity. These results proved that introduction of a minimal set of four transgenes enables de novo biosynthesis of astaxanthin in the rice endosperm. This work provides a successful example for synthetic biology in plants and biofortification in crops; the biofortified rice products generated by this study could be consumed as health-promoting foods and processed to produce dietary supplements. PMID- 30296602 TI - New human isolates of Trypanosoma cruzi confirm the predominance of hybrid lineages in domestic transmission cycle of the Argentinean Chaco. AB - Trypanosoma cruzi, the etiological agent of Chagas disease, was initially classified into 6 Discrete Typing Units (DTUs). The hybrid DTUs TcV and TcVI are the most frequent in domestic transmission cycles throughout the Southern Cone countries of South America. Here, we genotyped parasite isolates from human residents in Pampa del Indio municipality, Chaco, to further characterize the structure of T. cruzi populations, and to assess the degree of overlapping between the domestic and sylvatic transmission cycles. Artificial xenodiagnostic tests were performed to blood samples from 125 T. cruzi-seropositive people (age range, 3-70 years) who represented 14.3% of all seropositive residents identified. Parasites were obtained from feces of T. cruzi-infected Triatoma infestans examined 30 or 60 days after blood-feeding, and grown in vitro. The cultured parasites were genotyped by means of two PCR-based protocols. DTUs were determined from 39 (31%) patients residing in 28 dwellings. The only DTUs identified were TcV (92%) and TcVI (8-36%). Households with more than one parasite isolate consistently displayed the same DTU. Further sequencing of a fragment of the TcMK gene from selected samples argue against the occurrence of mixed TcV-TcVI infections in the study population. Sequencing data revealed an unexpected degree of genetic variability within TcV including two apparently robust subgroups of isolates. Our results for human residents confirm the predominance of hybrid lineages (TcV and to a much lesser extent TcVI) and the absence of sylvatic genotypes (TcI and TcIII) in (peri)domestic transmission cycles in the Argentinean Chaco area. 245 words.

PMID- 30296604 TI - Design and operation of urban wastewater systems considering reliability, risk and resilience. AB - Reliability, risk and resilience are strongly related concepts and have been widely utilised in the context of water infrastructure performance analysis. However, there are many ways in which each measure can be formulated (depending on the reliability of what, risk to what from what, and resilience of what to what) and the relationships will differ depending on the formulations used. This research has developed a framework to explore the ways in which reliability, risk and resilience may be formulated, identifying possible components and knowledge required for calculation of each and formalising the conceptual relationships between specified and general resilience. This utilises the Safe & SuRe framework, which shows how threats to a water system can result in consequences for society, the economy and the environment, to enable the formulations to be derived in a logical manner and to ensure consistency in any comparisons. The framework is used to investigate the relationship between levels of reliability, risk and resilience provided by multiple operational control and design strategies for an urban wastewater system case study. The results highlight that, although reliability, risk and resilience values may exhibit correlations, designing for just one is insufficient: reliability, risk and resilience are complementary rather than interchangeable measures and one cannot be used as a substitute for another. Furthermore, it is shown that commonly used formulations address only a small fraction of the possibilities and a more comprehensive assessment of a system's response to threats is necessary to provide a comprehensive understanding of risk and resilience. PMID- 30296605 TI - Large greenhouse gases emissions from China's lakes and reservoirs. AB - Freshwaters are important sources of greenhouse gases (GHGs) to the atmosphere that may partially offset the terrestrial carbon sink. However, current emission estimates from inland waters remain uncertain due to data paucity in key regions with a large freshwater surface area, such as China. Here, we show that the areal fluxes of GHGs (carbon dioxide, methane, and nitrous oxide) from lakes and reservoirs in China are much larger than previous estimates. Our work summarized data from 310 lakes and 153 reservoirs, and revealed diffusive emissions of 1.56 (95% confidence interval: 1.12-2.00) Tg C-CH4/y and 25.2 (20.8-29.5) Tg C-CO2/y from reservoirs and lakes. Chinese lakes and reservoirs emit 175.0 (134.7-215.3) Tg CO2 equivalent, with 73.4% of this forcing contributed by lakes. These aquatic sources are equivalent to 14.1%-22.6% of China's estimated terrestrial carbon sink. Our results suggest a disproportionally high contribution of China's reservoirs and lakes to national and global GHGs emissions, highlighting major data gaps and the need of including more artificial and natural lakes data from developing countries like China in global GHGs budgets. PMID- 30296606 TI - Selection of media for the design of ballasted flocculation processes. AB - Conventional clarification processes imply specific facility footprints that translate into important capital costs. Ballasted flocculation, consisting of injecting ballast medium to increase floc specific gravity and size, is being increasingly used in the water industry owing to its potential for design with very high superficial velocities. However, no systematic approach has yet been proposed to compare and select an appropriate ballast medium with respect to its specific gravity and size. In order to facilitate this procedure, this research project explores the hypothesis that flocculation performance is controlled by the surface area of the medium available for ballasted flocculation. This hypothesis was tested at laboratory scale by evaluating five ballast media with differing specific gravity and size: granular activated carbon, anthracite, silica sand, ilmenite, and magnetite sand having specific gravities of 1.24, 1.45, 2.62, 3.70, and 5.08, respectively. Flocculation kinetics were monitored by measuring floc size through microscopy and with a camera installed directly on the jar-test beaker. Settling performance was monitored using turbidity measurements. This study shows that all ballast media, when expressed as total surface available during flocculation, required similar surface concentrations to achieve settled water turbidity near 1 NTU and lower. In addition, the effects from the ballast media size and specific gravity were lowered for settling time longer than 3 min. Inversely, for settling time of 12 s, larger and denser media produced lower settled water turbidity. For certain applications, lighter ballast media may be more economical because they offer more available surface area for a given mass concentration, hence reducing the amount of ballast media required in the flocculation tank. Finally, the ballast media point of zero charge and shape were not identified as key criteria for ballasted flocculation. PMID- 30296607 TI - Biological treatment of produced water coupled with recovery of neutral lipids. AB - Produced water (PW) is the largest waste stream generated by oil and gas industry. It is commonly treated by physical-chemical processes due to high salt content and poor biodegradability of water insoluble compounds, such as n alkanes. N-alkanes can represent a major fraction of organic contaminants within PW. In this study the possibility of simultaneous n - alkane biodegradation and production of neutral lipids in a concentrated PW stream with A. borkumenis SK2 as the sole reactor inoculum was investigated. N-alkane removal efficiency up to 99.6%, with influent alkane COD of 7.4 g/L, was achieved in a continuously operated reactor system. Gas chromatography results also showed that the majority of other non-polar compounds present in the PW were biodegraded. Biodegradation of n-alkanes was accompanied by simultaneous production of neutral lipids, mostly wax ester (WE)-alike compounds. We demonstrate, that under nutrient limited conditions and 108.9 +/- 3.3 mg/L residual n-alkane concentration the accumulation of extracellular WE-alike compounds can be up to 12 times higher compared to intracellular, reaching 3.08 grams per litre of reactor volume (g/Lreactor) extracellularly and 0.28 g/Lreactor intracellularly. With residual n alkane concentration of 311.5 +/- 34.2 mg/L accumulation of extracellular and intracellular WE-alike compounds can reach up to 6.15 and 0.91 g/Lreactor, respectively. To the best of our knowledge simultaneous PW treatment coupled with production of neutral lipids has never been demonstrated before. PMID- 30296608 TI - Applications of carbon quantum dots (CQDs) in membrane technologies: A review. AB - Carbon quantum dots (CQDs), which are a fascinating class of nanostructured carbons, have recently attracted extensive attention in the field of membrane technologies for their applications in separation processes. This is because they possess two unique advantages. Their productions are facile and inexpensive, while their physicochemical properties such as ultra-small sizes, good biocompatibility, high chemical inertness, tunable hydrophilicity, rich surface functional groups and antifouling characteristics are highly desirable. Leveraging on these, researchers have explored their utilizations in various membrane designs for reverse osmosis (RO), ultrafiltration (UF), nanofiltration (NF), forward osmosis (FO), pressure retarded osmosis (PRO), membrane distillation (MD), and organic solvent nanofiltration (OSN) processes. In particular, CQDs have especially stimulated exploration in the field of water treatment by membrane technologies since biocompatibility of membrane materials is of utmost importance to ensure safety of drinking water. In addition, CQDs are in a favorable position for achieving unprecedented performance of membrane separation processes in water treatment, in the light of substantial efficiency enhancement and antifouling propensity as discovered in recent studies. In this article, we will review the progress in the development of CQD incorporated membranes with discussions on their challenges and perspectives. PMID- 30296609 TI - Rhamnolipid from a Lysinibacillus sphaericus strain IITR51 and its potential application for dissolution of hydrophobic pesticides. AB - Rhamnolipid produced from a Lysinibacillus sphaericus IITR51 was characterized and its ability for dissolution of hydrophobic pesticides were evaluated. L. sphaericus produced 1.6 g/L of an anionic biosurfactant that reduced surface tension from 72 N/m to 52 N/m with 48% emulsification index. The biosurfactant was found stable over a wide range of pH (4.0-10.0), temperature (4-100 degrees C), salt concentration (2-14%) and was identified as rhamnolipid. At the concentration of 90 mg/L rhamnolipid showed enhanced dissolution of alpha-, beta endosulfan, and gamma-hexachlorocyclohexane up to 7.2, 2.9, and 1.8 folds, respectively. The bacterium utilized benzoic acid, chlorobenzene, 3- and 4 chlorobenzoic acid as sole source of carbon and was found resistant to arsenic, lead and cadmium. Furthermore, the isolated biosurfactant showed antimicrobial activities against different pathogenic bacteria. The results obtained indicate the usefulness of rhamnolipid for enhanced dissolution and thereby increasing the bioavailability. PMID- 30296611 TI - Copper accumulation and toxicity in earthworms exposed to CuO nanomaterials: Effects of particle coating and soil ageing. AB - Engineered nanomaterials (ENMs) may be functionalised with a surface coating to enhance their properties, but the ecotoxicity of the coatings and how hazard changes with ageing in soil is poorly understood. This study determined the toxic effect of CuO ENMs with different chemical coatings on the earthworm (Eisenia fetida) in fresh soil, and then after one year in aged soil. In both experiments, earthworms were exposed for 14 days to the CuO materials at nominal concentrations of 200 and 1000 mg Cu kg-1 dry weight and compared to CuSO4. In the fresh soil experiment, CuO-COOH was found to be the most acutely toxic of the nanomaterials (survival, 20 +/- 50%), with tenfold increase of total Cu in the earthworms compared to controls. Sodium pump activity was reduced in most CuO ENM treatments, although not in the CuSO4 control. There was no evidence of glutathione depletion or the induction of superoxide dismutase (SOD) activity in any treatment. Histology showed a mild hypoplasia of mucous cells in the epidermis with some nanomaterials. In the aged soil, the CuO-NH4+ was the most acutely toxic ENM (survival 45 +/- 3%) and Cu accumulation was lower in the earthworms than in the fresh soil study. Depletion of tissue Mn and Zn concentrations were seen in earthworms in aged soil, while no significant effects on sodium pump or total glutathione were observed. Overall, the study showed some coating-dependent differences in ENM toxicity to earthworms which also changed after a year of ageing the soil. PMID- 30296610 TI - Climate change risk perception in global: Correlation with petroleum and liver disease: A meta-analysis. AB - BACKGROUND: Liver diseases have been bound to environmental factors, inclusive of air pollution. The exposure of workers to petrochemicals counts as a possible cause of Liver diseases, whereas results are inconsistent with the previous studies. In this study, a meta-analysis is conducted to assess the pooled risk. METHODS AND FINDING: A systematic search was performed by related researchers. Correlations are analyzed among petroleum and liver cirrhosis mortality, fatty liver, alanine amino transferase (abbreviated as ALT), aspartate amino transferase (abbreviated as AST). Pooled risk ratios (RR) with 95% confidence interval (CI) and effect size(ES) with 95% confidence interval are calculated. Sensitivity analysis and publication bias are also tested. Data are analyzed from 5 studies involving 296 participants. Results are incorporated through adopting a random effects meta-analysis. Working in a petrochemical plant shall not increase the death risk posed by cirrhosis (RR = 0.44, 95% CI [0.36; 0.54]). Yet the incidence of fatty liver increases (RR = 1.22, 95% CI [1.21; 1.23]). Abnormal incidence of ALT and AST also increases. CONCLUSIONS: Occupational exposure plays an important role in causing ALT abnormalities and fatty liver among oil workers, but not a risk factor of cirrhosis, AST abnormalities and liver cancer. PMID- 30296612 TI - Deep Tissue Incision Enhances Spinal Dorsal Horn Neuron Activity During Static Isometric Muscle Contraction in Rats. AB - Translational correlates to pain with activities after deep tissue injury have been rarely studied. We hypothesized that deep tissue incision causes greater activation of nociception-transmitting neurons evoked by muscle contraction. In vivo neuronal activity was recorded in 203 dorsal horn neurons (DHNs) from 97 rats after sham, skin-only, or skin + deep muscle incision. We evaluated DHN responses to static, isometric muscle contractions induced by direct electrical stimulation of the muscle. The effect of pancuronium on DHN response to contractions was also examined. Approximately 50% of DHNs with receptive fields in the hindpaw were excited during muscle contraction. One-second .5- and 1.0-g muscle contractions produced greater DHN activity after skin + deep muscle incision (median [interquartile range], 32 [5-39] impulses, P = .021; and 36 [26 46] impulses, P = .006, respectively) than after sham (6 [0-21] and 15 [8-32] impulses, respectively). Neuromuscular blockade with pancuronium inhibited the muscle contractions and DHN activation during electrical stimulation, demonstrating contraction-induced activation. The greater response of spinal DHNs to static muscle contraction after skin + deep muscle incision may model and inform mechanisms of dynamic pain after surgery. PERSPECTIVE: Completion of various activities is an important milestone for recovery and hospital discharge after surgery. Skin + deep muscle incision caused greater activation of nociception-transmitting DHNs evoked by muscle contraction compared with skin only incision. This result suggests an important contribution of deep muscle injury to activity-evoked hyperalgesia after surgery. PMID- 30296613 TI - Generalization and Extinction of Concept-BasedPain-Related Fear. AB - In chronic pain, pain-related fear seems to overgeneralize to safe stimuli, thus contributing to excessive fear and avoidance behavior. Evidence shows that pain related fear can be acquired and generalized based on conceptual knowledge. Using a fear conditioning paradigm, we investigated whether this concept-based pain related fear could also be extinguished. During acquisition, exemplars of 1 action category (conditioned stimuli [CSs]; eg, opening boxes) were followed by pain (CS+), whereas exemplars of another action category were not (CS-; eg, closing boxes). Participants reported more pain-related fear and expectancy toward exemplars of the CS+ category compared with those of the CS- category. During generalization, fear and expectancy spread to novel exemplars (generalization stimuli [GSs]) of the CS+ category (GS+), but not to those of the CS- category (GS-). During extinction, exemplars of both categories were presented in the absence of pain. At the end of extinction, participants no longer reported elevated fear or expectancy toward CS+ exemplars compared to CS- exemplars. These findings were not replicated in either the eye-blink startle or skin conductance measures. This is the first study to demonstrate extinction of concept-based pain-related fear, thus providing evidence for the potential of extinction-based techniques in the treatment of conceptual pain-related fear. PERSPECTIVE: This study demonstrates the acquisition, generalization, and extinction of concept-based pain-related fear in healthy participants. These are the first results to show that concept-based pain-related fear can be extinguished, suggesting that conceptual relationships between fear-inducing stimuli may also be important to consider in clinical practice. PMID- 30296614 TI - Does Sensorimotor Incongruence Trigger Pain and Sensory Disturbances in People With Chronic Low Back Pain? A Randomized Cross-Over Experiment. AB - Chronic low back pain (CLBP) has major public health implications, and underlying mechanisms are still unclear. Sensorimotor incongruence (SMI)-an ongoing mismatch between top-down motor output and predicted sensory feedback-may play a role in the course of chronic nonspecific low back pain. The hypothesis of this study was that the induction of SMI causes sensory disturbances and/or pain in people with CLBP and healthy volunteers. A sample of 66 people (33 people with CLBP and 33 healthy volunteers) participated in a visual feedback experiment involving real time images of their own lower backs-either during movement or in a static position-provided via a live video feed. Experimental SMI was induced via distorting visual feedback of the lower back during movement. There were no significant differences in sensory disturbances or pain intensity between experimental SMI and the other movement conditions in people with CLBP and healthy volunteers (P > .05). Static visual feedback had a significant effect on the intensity of sensory disturbances in people with CLBP (P = .038) and healthy volunteers (P < .001). In conclusion, experimental SMI did not affect sensory disturbances or pain in either group. Therefore, the research hypothesis was not supported. PERSPECTIVE: The results of this study show that sensorimotor incongruence does not cause additional symptoms and pain in people with chronic low back pain. The conceptual premise that sensorimotor incongruence is an underlying contributor in the course of pain in this population is not supported. PMID- 30296615 TI - Functional specialization for feature-based and symmetry-based groupings in multiple object tracking. AB - Our vision systems utilize attention to process dynamic visual information everyday. Multiple object tracking (MOT) is widely used for studying sustained attention in dynamic environments. Previous research reported inter-target grouping based on feature similarity (e.g., targets sharing the same color, size, or shape) can facilitate tracking. A recent study also found that symmetric relation among targets in MOT tasks can automatically improve tracking performance, and a greater grouping effect based on symmetry and feature was observed. However, grouping based on multiple feature cues didn't produce a greater grouping effect than grouping based on one feature cue. Why were groupings based on symmetry and feature additive, but two feature-based groupings were not? How stimulus-driven inter-target groupings based on color or symmetry improve the goal-directed target tracking process remains unknown. We hypothesized that symmetry-based and feature-based groupings would involve different cortical and subcortical areas, and color-based and color-shape-based groupings would be manifested in significant activity in the same regions. This study used functional magnetic resonance imaging (fMRI) to identify cortical and subcortical areas involved in feature-based and symmetry-based groupings respectively during tracking. The results of our experiment showed that lateral occipital (LO) cortex is involved in symmetry-based grouping during tracking. Bilateral putamen, temporal parietal junction (TPJ), and frontal eye field (FEF) are involved in the feature-based grouping. Our findings likely indicate that stimulus-driven inter-target symmetry-based grouping and feature-based grouping improve goal-directed target tracking in different ways. PMID- 30296616 TI - Beneficial effects of n-3 polyunsaturated fatty acids administration in a partial lesion model of Parkinson's disease: The role of glia and NRf2 regulation. AB - Omega-3 polyunsaturated fatty acids (n-3 PUFAs) have been widely associated to beneficial effect over different neurodegenerative diseases. In the present study, we tested the potential therapeutic effect of docohexanoic acid (DHA) and its hydroxylated derivate, DHAH, in a partial lesion model of Parkinson's disease (PD). One month before and four months after the striatal lesion with 6-OHDA was made, the animals were daily treated with DHA (50 mg/kg), DHAH (50 mg/kg), vehicle or saline, by intragastric administration. Animal groups under n-3 PUFA treatments exhibited a trend to improve in amphetamine-induced rotations and cylinder test. The beneficial effect seen in behavioral studies were confirmed with TH immunostaining. TH+ fibers and TH+ neurons increased in the experimental groups treated with both n-3 PUFAs, DHA and DHAH. Moreover, the n-3 PUFAs administration decreased the astrogliosis and microgliosis, in both the striatum and substantia nigra (SN), with a higher decrease of GFAP+ and Iba-1+ cells for the DHAH treated group. This experimental group also revealed a positive effect on Nrf2 pathway regulation, decreasing the positive Nrf2 immmunostaining in the striatum and SN, which revealed a potential antioxidant effect of this compound. Taking together, these data suggest a positive effect of n-3 PUFAs administration, and more concretely of DHAH, for PD treatment as it exhibited positive results on dopaminergic system, neuroinflammation and oxidative stress. PMID- 30296617 TI - A potential gain-of-function variant of SLC9A6 leads to endosomal alkalinization and neuronal atrophy associated with Christianson Syndrome. AB - Loss-of-function mutations in the recycling endosomal (Na+,K+)/H+ exchanger gene SLC9A6/NHE6 result in overacidification and dysfunction of endosomal-lysosomal compartments, and cause a neurodevelopmental and degenerative form of X-linked intellectual disability called Christianson Syndrome (CS). However, knowledge of the disease heterogeneity of CS is limited. Here, we describe the clinical features and underlying molecular and cellular mechanisms associated with a CS patient carrying a de novo missense variant (p.Gly218Arg; G218R) of a conserved residue in its ion translocation domain that results in a potential gain-of function. The patient manifested several core symptoms typical of CS, including pronounced cognitive impairment, mutism, epilepsy, ataxia and microcephaly; however, deterioration of motor function often observed after the first decade of life in CS children with total loss of SLC9A6/NHE6 function was not evident. In transfected non-neuronal cells, complex glycosylation and half-life of the G218R were significantly decreased compared to the wild-type transporter. This correlated with elevated ubiquitination and partial proteasomal-mediated proteolysis of G218R. However, a major fraction was delivered to the plasma membrane and endocytic pathways. Compared to wild-type, G218R-containing endosomes were atypically alkaline and showed impaired uptake of recycling endosomal cargo. Moreover, instead of accumulating in recycling endosomes, G218R was redirected to multivesicular bodies/late endosomes and ejected extracellularly in exosomes rather than progressing to lysosomes for degradation. Attenuated acidification and trafficking of G218R-containing endosomes were also observed in transfected hippocampal neurons, and correlated with diminished dendritic branching and density of mature mushroom-shaped spines and increased appearance of filopodia-like protrusions. Collectively, these findings expand our understanding of the genetic diversity of CS and further elucidate a critical role for SLC9A6/NHE6 in fine-tuning recycling endosomal pH and cargo trafficking, processes crucial for the maintenance of neuronal polarity and mature synaptic structures. PMID- 30296618 TI - Vitronectin promotes the vascularization of porous polyethylene biomaterials. AB - Rapid implant vascularization is a prerequisite for successful biomaterial engraftment. Vitronectin (VN) is a matricellular glycoprotein well known for its capability to interact with growth factors, proteases, and protease inhibitors/receptors. Since such proteins are highly relevant for angiogenic processes, we hypothesized that VN contributes to the tissue integration of biomaterials. Employing different in vivo and ex vivo microscopy techniques, engraftment of porous polyethylene (PPE) implants was analyzed in the dorsal skinfold chamber model in wild-type (WT) and VN-/- mice. Upon PPE implantation, vascularization of this biomaterial was severely compromised in animals lacking this matricellular protein. Proteome profiling revealed that VN deficiency does not cause major changes in angiogenic protein composition in the implants suggesting that VN promotes PPE vascularization via mechanisms modulating the activity of angiogenic factors rather than by directly enriching them in the implant. Consequently, surface coating with recombinant VN (embedded in Matrigel(r)) accelerated implant vascularization in WT mice by enhancing the maturation of a vascular network. Thus, VN contributes to the engraftment of PPE implants by promoting the vascularization of this biomaterial. Surface coating with VN might provide a promising strategy to improve the vascularization of PPE implants without affecting the host's integrity. STATEMENT OF SIGNIFICANCE: Porous polyethylene (PPE) is a biomaterial frequently used in reconstructive surgery. The proper vascularization of PPE implants is a fundamental prerequisite for its successful engraftment in host tissue. Although the overall biocompatibility of PPE is good, there are less favorable application sites for its use in tissue reconstruction mostly characterized by low blood supply. Employing advanced in vivo microscopy methods and proteomic analyses in genetically engineered mice, we here describe a previously unrecognized function of vitronectin (VN) that enables this abundantly present glycoprotein to particularly promote the vascularization of PPE biomaterial. These properties of VN specifically facilitate the formation of a dense vessel network within the implant which relies on modulating the activity of angiogenic mediators rather than on the enrichment of these factors in the implant. Consequently, surface coating with this matricellular protein effectively accelerated and intensified implant vascularization which might be beneficial for its implementation at unfavorable sites for implantation without affecting the host's integrity. PMID- 30296620 TI - Design and development of pH-responsive polyurethane membranes for intravaginal release of nanomedicines. AB - The objective of this study was to develop and characterize a novel intravaginal membrane platform for pH-triggered release of nanoparticles (NPs), which is essential for efficient intravaginal delivery of certain effective but acid labile therapeutic agents for sexually transmitted infections, such as small interfering RNA (siRNA). A pH-responsive polyurethane (PU) was electrospun into a porous nanofibrous membrane. The diameters of the fibers, as well as the thickness and pore sizes of the membrane under dry and wet conditions (pH 4.5 and 7.0), were determined from scanning electron microscopy (SEM) micrographs. pH dependent zeta-potential (zeta) of the membrane was evaluated using a SurPASS electrokinetic analyzer. VisiblexTM color-dyed polystyrene NPs (PSNs, 200 nm, COOH) and CCR5 siRNA-encapsulated solid lipid NPs (SLNs) were used for in vitro NP release studies in a vaginal fluid simulant (VFS) at pH 4.5 (normal physiological vaginal pH) and 7.0 (vaginal pH neutralization by semen). During 24 h of incubation in VFS, close-to-zero PSNs (2 +/- 1%) and 28 +/- 4% SLNs were released through the PU membrane at pH 4.5, whereas the release of PSNs and SLNs significantly increased to 60 +/- 6% and 59 +/- 8% at pH 7.0, respectively. The pH-responsive release of NPs hinged on the electrostatic interaction between the pH-responsive membrane and the anionic NPs, and the change in pH-responsive morphology of the membrane. In vitro biocompatibility studies of the membrane showed no significant cytotoxicity to VK2/E6E7 human epithelial cells and Sup-T1 human T-cells and no significant changes in the expression of pro-inflammatory cytokines (IL-6, IL-8, and IL-1beta). Overall, the porous pH-responsive PU membrane demonstrated its potential in serving as a "window" membrane in reservoir-type intravaginal rings (IVRs) for pH-responsive intravaginal release of NPs. STATEMENT OF SIGNIFICANCE: Stimuli-responsive intravaginal nanoparticle release is achieved for the first time through a new electrospun pH-responsive polyurethane (PU) semi-permeable membrane, which can serve as a "window" membrane in the reservoir-type IVR for the prevention of human immunodeficiency virus (HIV) transmission. Almost no release of nanoparticles was observed at normal pH in the female genital tract (in vaginal fluid simulant [VFS], at pH 4.5); however, a continuous release of NPs was observed at elevated pH in the female genital tract (in VFS, at pH 7.0). This pH-responsive intravaginal release can reduce side effect and drug resistance by avoiding unnecessary exposure. The PU semi-permeable membrane demonstrated potential use as biomaterials for "smart" intravaginal nanoparticle release and has great potential to protect women from HIV. PMID- 30296619 TI - Characterization of a Cell-Assembled extracellular Matrix and the effect of the devitalization process. AB - We have previously shown that the Cell-Assembled extracellular Matrix (CAM) synthesized by normal, human, skin fibroblasts in vitro can be assembled in a completely biological vascular graft that was successfully tested in the clinic. The goal of this study was to perform a detailed analysis of the composition and the organization of this truly bio-material. In addition, we investigated whether the devitalization process (dehydration) used to store the CAM, and thus, make the material available "off-the-shelf," could negatively affect its organization and mechanical properties. We demonstrated that neither the thickness nor the mechanical strength of CAM sheets were significantly changed by the dehydration/freezing/rehydration cycle. The identification of over 50 extracellular matrix proteins highlighted the complex composition of the CAM. Histology showed intense collagen and glycosaminoglycan staining throughout the CAM sheet. The distribution of collagen I, collagen VI, thrombospondin-1, fibronectin-1, fibrillin-1, biglycan, decorin, lumican and versican showed various patterns that were not affected by the devitalization process. Transmission electron microscopy analysis revealed that the remarkably dense collagen network was oriented in the plane of the sheet and that neither fibril density nor diameter was changed by devitalization. Second harmonic generation microscopy revealed an intricate, multi-scale, native-like collagen fiber orientation. In conclusion, this bio-material displayed many tissue-like properties that could support normal cell-ECM interactions and allow implantation without triggering degradative responses from the host's innate immune system. This is consistent with its success in vivo. In addition, the CAM can be devitalized without affecting its mechanical or unique biological architecture. STATEMENT OF SIGNIFICANCE: The extracellular matrix (ECM) defines biological function and mechanical properties of tissues and organs. A number of promising tissue engineering approaches have used processed ECM from cadaver/animal tissues or cell-assembled ECM in vitro combined with scaffolds. We have shown the clinical potential of a scaffold-free approach based on an entirely biological material produced by human cells in culture without chemical processing. Here, we perform a comprehensive analysis of the properties of what can truly be called a bio-material. We also demonstrate that this material can be stored dried without losing its remarkable biological architecture. PMID- 30296621 TI - Micro-Raman high-pressure investigation on the malaria pigment hematin anhydride (beta-hematin). AB - The effect of pressure on the Raman and fluorescence spectra of hematin anhydride (beta-hematin) is reported. In a diamond-anvil cell, DAC, with applied pressures up to 41 kbar, the Raman spectrum undergoes a series of intensity enhancements and increases in energy for many of the Raman-active bands up to a pressure of ~27 kbar. At higher pressures, there is either a leveling out or a decrease in the energies of these vibrational modes. The fluorescence bands also undergo a series of pressure- sensitive changes where, up to 10 kbar, there is a marked quenching of the intensity of the emissive bands, which is accompanied by a net increase in energy of the vibrational bands. The results are interpreted in terms of a high-pressure phase change, to account for the Raman shifts, and a separate defect or surface site of the emissive state, which is more efficiently quenched at higher pressure. PMID- 30296622 TI - Patterns of Stroke Transfers and Identification of Predictors for Thrombectomy. AB - BACKGROUND: Interhospital transfers for endovascular thrombectomy (EVT) evaluation have increased since the publication of landmark neuroendovascular stroke trials in 2015. The lack of guidelines to select potential EVT candidates prior to transfer can lead to instances where, despite considerable costs and transport risks, transferred patients do not ultimately undergo EVT. Our aim was to characterize the patterns and identify predictors for EVT on transfer. METHODS: In this observational cohort study, we retrospectively analyzed patients with acute ischemic stroke (AIS) transferred to our institution for EVT evaluation from January 2015 to March 2016. Clinical and radiographic predictors for EVT on transfer were determined with multivariable logistic regression analysis. RESULTS: A total of 103 transfer patients with AIS were included in the study, and 52% were women. A higher collateral score (P < 0.01), a higher National Institutes of Health Stroke Scale (NIHSS) score (P < 0.01), computed tomography angiography (CTA) at referring hospital (P < 0.01), and large vessel occlusion on arrival CTA (P < 0.01) were significant in patients who underwent EVT on univariable analysis. More than half (61.1%) of transfers were futile and primarily related to absence of large vessel occlusion on arrival. A higher collateral score (P = 0.02), a higher NIHSS score (P = 0.006), and having undergone a CTA at the referring center (P = 0.002) remained the independent predictors of EVT. The C statistic for the model was 0.94. CONCLUSIONS: A higher collateral score, the acquisition of CTA imaging at the referring centers, and a higher NIHSS score independently predicted EVT on transfer. PMID- 30296623 TI - Navigated Transcranial Magnetic Stimulation In A Patient With A Cranioplasty In Situ: A Safe And Accurate Procedure. AB - BACKGROUND: and importance: Navigated Transcranial Magnetic Stimulation (nTMS) is a non-surgical mapping technique used in mapping of motor and language eloquent areas within and / or surrounding brain tumours. Previous reports support this as a safe technique with minor side effects associated with minor headaches and discomfort around the stimulation area. Currently there are no published reports concerning the accuracy and safety of this procedure in patients with a titanium cranioplasty in situ. CLINICAL PRESENTATION: A 59 year-old lady was diagnosed with a recurrent glioma in the context of increasing seizure frequency, left sided numbness and weakness. She was diagnosed with a WHO grade 2 oligodendroglioma 10 years prior to her presentation which was initially treated with radiotherapy, and then surgical resection of this lesion five years later. The procedure was complicated with a wound infection, treated with a craniectomy and wound washout, followed by a titanium cranioplasty. Before proceeding with surgery for recurrence, nTMS was performed for motor mapping. No complications were identified. She underwent a craniotomy for tumour resection with GLIOLAN(r) and the tumour was completely removed. Intra-operatively, the direct cortical stimulation correlated with the pre-operative nTMS. The pathological diagnosis on recurrence was an Anaplastic Oligodendroglioma grade III and the patient is currently undergoing adjuvant chemotherapy. CONCLUSION: This report confirms that nTMS is a safe and accurate procedure in patients who have a titanium cranioplasty in situ. PMID- 30296624 TI - Cost Effectiveness of Dolutegravir as a First-Line Treatment Option in the HIV-1 Infected Treatment-Naive Patients in Russia. AB - OBJECTIVES: To evaluate the cost effectiveness of dolutegravir + abacavir/lamivudine (DTG + ABC/3TC) compared with raltegravir + abacavir/lamivudine (RAL + ABC/3TC) and ritonavir-boosted darunavir + abacavir/lamivudine (DRV/r + ABC/3TC) in HIV-1-infected treatment-naive patients in Russia. METHODS: A dynamic Markov model was developed with five response states and six CD4+-based health states. Efficacy estimated as probability of viral suppression (HIV RNA <50 copies/ml) at 48 weeks was obtained from a published network meta-analysis. Baseline cohort characteristics and health state utilities were informed using DTG phase 3 clinical trials. Health care resource use was obtained from literature and costed using published unit costs. Costs (presented in Russian rubles) included antiretroviral drug costs; HIV management costs such as routine care; costs of treating cardiovascular conditions, opportunistic infections, and drug-related adverse effects; and mortality costs. A patient lifetime analysis was conducted using the societal perspective. Outcomes were quality-adjusted life-years (QALYs), life-years, incremental cost per QALY ratio, and incremental cost per responder. RESULTS: The viral suppression rate among patients receiving DTG + ABC/3TC was 71.7% compared with 65.2% for RAL + ABC/3TC and 59.6% for DRV/r + ABC/3TC. The mean duration of response per patient was 116.6 months for DTG + ABC/3TC, 108.6 months for RAL + ABC/3TC, and 98.9 months for DRV/r + ABC/3TC. Total discounted costs for treatment over patient lifetime were RUB 2.89, 5.32, and 4.38 million for DTG + ABC/3TC, RAL + ABC/3TC, and DRV/r + ABC/3TC, respectively. Lifetime discounted QALYs were 12.73 for patients on DTG + ABC/3TC and 12.72 each for patients on RAL + ABC/3TC and DRV/r + ABC/3TC. DTG + ABC/3TC thus dominated the other two alternatives. CONCLUSIONS: With lower costs, higher response rates, and comparable QALYs, DTG + ABC/3TC can be considered as a cost-effective alternative. PMID- 30296625 TI - Multi-dimensional proprio-proximus machine learning for assessment of myocardial infarction. AB - This work presents a novel analysis methodology that utilises high-resolution, multi-dimensional information to better classify regions of the left ventricle after myocardial infarction. Specifically, the focus is to determine degree of infarction in regions of the left ventricle based on information extracted from cardiac magnetic resonance imaging. Enhanced classification accuracy is achieved using three mechanisms: Firstly, a plurality of indices/features is used in the pattern classification process, rather than a single index/feature (hence the term "multi-dimensional). Secondly, the method incorporates not only the indices/features of the region in consideration, but also indices/features from the neighbouring regions (hence the term "proprio-proximus"). Thirdly, advanced machine learning techniques are used for both feature selection and pattern classification process to ameliorate the effect of class-imbalance existing in the data. Numerical results from multiple experiments on real data showed that using multiple features improved the ability to distinguish between infarcted and non-infarcted remote segments, and using neighbouring information improved classification performance. The proposed methodology is general and can be adapted for the analysis of biological functions of other human organs. PMID- 30296626 TI - An iterative multi-atlas patch-based approach for cortex segmentation from neonatal MRI. AB - Brain structure analysis in the newborn is a major health issue. This is especially the case for preterm neonates, in order to obtain predictive information related to the child development. In particular, the cortex is a structure of interest, that can be observed in magnetic resonance imaging (MRI). However, neonatal MRI data present specific properties that make them challenging to process. In this context, multi-atlas approaches constitute an efficient strategy, taking advantage of images processed beforehand. The method proposed in this article relies on such a multi-atlas strategy. More precisely, it uses two paradigms: first, a non-local model based on patches; second, an iterative optimization scheme. Coupling both concepts allows us to consider patches related not only to the image information, but also to the current segmentation. This strategy is compared to other multi-atlas methods proposed in the literature. Experiments on dHCP datasets show that the proposed approach provides robust cortex segmentation results. PMID- 30296627 TI - Chemical profiling of the street cocktail drug 'nyaope' in South Africa using GC MS I: Stability studies of components of 'nyaope' in organic solvents. AB - Nyaope, a street drug commonly found in South Africa, is a mixture of low grade heroin, cannabis products, antiretroviral drugs and other materials added as cutting agents. It is a highly physiologically addictive substance which is smoked by users. Little work has been published on the chemical analysis and profiling of nyaope. Sample preparation prior to chromatographic or spectrometric analysis normally involves dissolution of the sample in an organic solvent. This study determined the most suitable organic solvent in which the common components of nyaope, namely Delta9-tetrahydrocannabinol, diamorphine, caffeine, dextromethorphan, phenacetin and the antiretrovirals efavirenz and nevirapine, which have different chemical characteristics, are stable during extraction and prior to analysis of nyaope samples i.e. autosampler stability. Street samples of cannabis (Delta9-tetrahydrocannabinol), heroin (diamorphine) and antiretrovirals were mixed to mimic a nyaope sample and dissolved in the organic solvents dichloromethane, ethanol, ethyl acetate, hexane, isopropanol and tertiary butyl alcohol. Analysis was performed after intervals of 0, 1, 6, 8, 24, 48 and 72h, prior to analysis by gas chromatography-mass spectrometry. Tertiary butyl alcohol resulted in the most stable extracts of the main nyaope components after 72h of storage. The analysis was also repeated on actual street samples of nyaope. These results show that tertiary butyl alcohol is a suitable solvent for sample preparation for the identification, comparison and profiling of nyaope samples. PMID- 30296628 TI - Bayesian interpretation of discrete class characteristics. AB - Bayesian interpretation of forensic evidence has become dominated by the likelihood ratio (LR) with a large LR generally considered favourable to the prosecution hypothesis, HP, over the defence hypothesis, HD. However, the LR simply quantifies by how much the prior odds ratio of the probability of HP relative to HD has been improved by the forensic evidence to provide a posterior ratio. Because the prior ratio is mostly neglected, the posterior ratio is largely unknown, regardless of the LR used to improve it. In fact, we show that the posterior ratio will only favour HP when LR is at least as large as the number of things that could possibly be the source of that evidence, all being equally able to contribute. This restriction severely limits the value of evidence to the prosecution when only a single, discrete class characteristic is used to match a subset of these things to the evidence. The limitation can be overcome by examining more than one individual characteristic, as long as they are independent of each other, as they are for the genotypes at multiple loci combined for DNA evidence. We present a criterion for determining how many such characteristics are required. Finally, we conclude that a frequentist interpretation is inappropriate as a measure of the strength of forensic evidence precisely because it only estimates the denominator of the LR. PMID- 30296629 TI - Facial approximation of Tycho Brahe's partial skull based on estimated data with TIVMI-AFA3D. AB - The virtual approach in physical and forensic anthropology is increasingly used to further analyze human remains, but also to propose new didactic means for visualization and dissemination of scientific results. Computerized facial approximation (FA) offers an alternative to manual methods, but usually requires a complete facial skeleton to allow for the estimation of the facial appearance of an individual. This paper presents the case of Tycho Brahe, Danish astronomer born during the XVIth century, whose remains were reanalyzed at the occasion of a short exhumation in 2010. Cranial remains of Brahe were poorly preserved, with only a partial facial skeleton, and virtual anthropology tools were used to estimate the missing parts of his skull. This 3D restoration was followed by a FA using TIVMI-AFA3D, subsequently textured with graphic tools. The result provided an interesting estimate that was compared with portraits of the astronomer. The impact of the missing data estimation was investigated by performing FAs on 10 complete test subjects and the same 10 subjects after cropping and estimating 50% of the landmarks (reproducing the preservation state of Tycho Brahe's cranial remains). The comparison between the FA based on the complete and incomplete skulls of the same subject produced a visual assessment of the estimation impact on FAs which is relatively low. This procedure is an alternative to manual methods and offers a reproducible estimate of a face based on incomplete cranial remains. Although the case report concerns a historical individual, the robust automatic estimation of missing landmarks followed by a FA has value for forensic caseworks as a support to the identification process. PMID- 30296630 TI - Secondary extinction reduces reinstatement of threat expectancy and conditioned skin conductance responses in human fear conditioning. AB - BACKGROUND AND OBJECTIVES: Secondary extinction refers to the phenomenon that extinction of one conditioned stimulus (CS) results in the reduction of conditioned responses for other CSs conditioned with the same unconditioned stimulus (US). Previous research with rats has demonstrated that secondary extinction can interfere with the return of conditioned fear after a reinstatement manipulation. Here we investigated this phenomenon in two pre registered studies in humans. METHOD: In both experiments, distinct CSs were paired with an electrical stimulation. Next, conditioned reactions to both CSs were extinguished and thereafter reinstated through the administration of three unsignaled electrical stimulations. Crucially, before participants continued with the reinstatement test, half of the participants received secondary extinction trials whereas the other half did not receive these trials. RESULTS: Our results indicate that secondary extinction reduced reinstatement of threat expectancies and skin conductance responses, but the effect on skin conductance was only found in the second experiment. LIMITATIONS: The studies were conducted in a laboratory setting with healthy students. Additional research will be required to determine the feasibility of applying secondary extinction in a (sub)clinical context. CONCLUSIONS: To our knowledge, this is the first demonstration of secondary extinction and its effect on reinstatement of conditioned fear in humans. We relate our findings to the earlier research with rats and discuss their relevance for exposure therapy. PMID- 30296631 TI - Use of flow cytometry in forensic medicine: Current scenario and future prospects. AB - Several methodologies are being used on different biological, physical and chemical indicators to determine the postmortem interval (PMI); however, most of them are not completely accurate. Flow cytometry is an emerging technology widely used for single cell analysis in the field of clinical pathology. Studies on flow cytometry and its application in the field of forensic medicine were retrieved from systematic web searched of different databases including "MEDLINE", "ScienceDirect", "PubMed" and "Google Scholar" using keywords forensic science; forensic medicine; forensic investigation; flow cytometry; DNA; postmortem interval; vitreous humour with the last search performed in January 2018. A total of 43 publications have been reviewed, and out of them 22 studies met our criteria and have been cited in this article. A handful of studies have evaluated the application of flow cytometry in forensic medicine for estimation of the PMI and identification of the perpetrator of sexual assault cases. Flow cytometry is also useful for quantifying the ABH antigens in red blood cells as well as in other human samples that can be further used for personal identification. In conclusion, flow cytometry is more sensitive, faster and easy compared to the other methods of investigation, thus making it a preferred method. However, a large numbers of studies with the application of flow cytometry on different cases of death are required to establish a universally accepted rate of DNA degradation to avoid errors in judgment. PMID- 30296632 TI - High vigabatrin dosage is associated with lower risk of infantile spasms relapse among children with tuberous sclerosis complex. AB - After initially successful treatment of infantile spasms, the long-term cumulative risk of relapse approaches 50%, and there is no established protocol to mitigate this risk. Although vigabatrin may be an effective means to prevent relapse, there is little guidance as to ideal duration and dosage. Using a cohort of children with infantile spasms and tuberous sclerosis complex (TSC), we evaluated the potential association of post-response VGB treatment and the rate of infantile spasms relapse. Patients with infantile spasms and clinical response to vigabatrin were identified among a multicenter prospective observational cohort of children with TSC. For each patient we recorded dates of infantile spasms onset, response to vigabatrin, relapse (if any), and quantified duration and dosage of vigabatrin after response. Time to relapse as a function of vigabatrin exposure was evaluated using survival analyses. We identified 50 children who responded to VGB. During a median follow-up of 16.6 months (IQR 10.3 22.9), 12 (24%) patients subsequently relapsed after a median of 7.8 months (IQR 3.1-9.6). Relapse occurred after VGB discontinuation in four patients, and during continued VGB treatment in the remaining eight cases. In survival analyses, risk of relapse was unaffected by the presence or absence of VGB treatment (HR 0.31, 95%CI 0.01-28.4, P = 0.61), but weighted-average dosage was associated with marked reduction in relapse risk: Each 50 mg/kg/d increment in dosage was associated with 61% reduction in risk (HR 0.39, 95%CI 0.17 - 0.90, P = 0.026). This study suggests that the risk of infantile spasms relapse in TSC may be reduced by high-dose vigabatrin treatment. PMID- 30296633 TI - The use of involuntary treatment among older adults with cognitive impairment receiving nursing care at home: A cross-sectional study. AB - BACKGROUND: Respect for inherent dignity and individual autonomy is a basic principle in health care. However, several studies indicate that care-dependent older adults with a cognitive impairment, receiving nursing care at home, are at risk of care without their consent, referred to as 'involuntary treatment'. This includes the application of physical restraints (e.g. measures to prevent leaving bed or chair), psychotropic drugs (e.g. antidepressants, sedatives) and non consensual care (e.g. forced hygiene, hiding medication). Research about involuntary treatment is scarce and only recently first studies have been conducted. OBJECTIVE: To investigate 1) the prevalence of involuntary treatment, 2) associated factors and 3) who requests and applies their use among older adults with cognitive impairment receiving nursing care at home. DESIGN: Cross- sectional study. SETTING: Homes of older adults receiving nursing care from district nurses in the eastern part of Belgium. PARTICIPANTS: Data were collected from 1194 randomly selected older adults with cognitive impairments receiving nursing care at home (mean age 83; 67% female). METHOD: District nurses completed an online questionnaire for each selected older adult in their caseload. Involuntary treatment was measured using a questionnaire identifying use of physical restraints, psychotropic medication and non-consensual care. In addition who requests involuntary treatment and who applies it was examined. Older adults sociodemographic characteristics, diagnosis of dementia, activities of daily living (ADL), cognitive status and informal caregiver burden were assessed. RESULTS: Involuntary treatment was used in 52% (95%; CI 49-55) of the total sample. Non-consensual care was most often used (73%; 95% CI 70-77), followed by psychotropic drugs (43%; 95% CI 39-47) and physical restraints (38%; 95% CI 35 42). The use of involuntary treatment was associated with dependency for activities of daily life (OR 1.50; 95% CI 1.33-1.69), cognitive impairment (1.39; 95% CI 1.25-1.55), informal caregiver burden (OR 1.05; 95% CI 1.01-1.10) and aging (OR 0.97; 95% CI 0.95-0.99). Informal caregivers (71%), followed by general practitioners (47%) most frequently requested the use of involuntary treatment, and nurses (81%) mostly applied it. CONCLUSION: In Belgium, involuntary treatment is often used in older adults with a cognitive impairment receiving nursing care at home. The implication of this study for clinical practice is that it confirms the need to develop an approach to prevent and reduce it. Further research is needed to plan and develop such an approach, in order to prevent and reduce the use of involuntary treatment. PMID- 30296634 TI - Intention, beliefs and mood assessed using electronic diaries predicts attendance at cardiac rehabilitation: An observational study. AB - BACKGROUND: Cardiac rehabilitationis effective in promoting physical/psychological recovery following acute coronary syndrome. Yet, rates of attendance at outpatient cardiac rehabilitation by eligible patients are low. OBJECTIVES: This study examined the determinants of attendance at outpatient cardiac rehabilitation in acute coronary syndrome patients following discharge until cardiac rehabilitation commencement. DESIGN: A weekly electronic diary measured cardiac-related cognitions and mood and examined their relation to attendance at outpatient cardiac rehabilitation. SETTINGS: Three United Kingdom National Health Service secondary care settings in two Health Board areas in Scotland. PARTICIPANTS: Acute coronary syndrome patients were recruited from March 2012 to June 2013 prior to hospital discharge. Of 488 eligible patients referred for cardiac rehabilitation, 214 consented. METHODS: Consecutive patients completed a pre-hospital discharge questionnaire targeting age, diagnosis, social class and smoking history. Acute coronary syndrome patients then completed a weekly electronic diary from the first week of discharge until the start of cardiac rehabilitation. Multilevel structural equation models estimated the effects of initial, i.e. baseline and rate of change in cardiac-related cognition and mood on attendance. Intention to attend cardiac rehabilitation was reflected, log transformed, reported thereafter as "do not intend". The role of "do not intend" was explored as a mediator of the relationship between cardiac-related cognition and mood on attendance. RESULTS: 166 participants provided, on average, 5 weeks of diary entries before cardiac rehabilitation commenced. High intention (i.e. low "do not intend") to attend CR and its rate of increase over time predicted attendance. Low negative emotional representation, high perceived necessity, high confidence in maintaining function, low negative affect, and high positive affect following discharge predicted attendance at cardiac rehabilitation. The rate of change in cardiac-related mood and these cognitions was not predictive. Baseline and rate of change in "do not intend" entirely mediated relationships between a) perceived necessity, b) negative affect and attendance at cardiac rehabilitation. CONCLUSIONS: Negative affect in the first weeks following discharge represents the key challenge to a patient maintaining their intention to attend cardiac rehabilitation. Intervention to improve attendance should focus on improving intention to attend following discharge and during recovery by improving patient understanding of cardiac rehabilitation and reducing negative affect. PMID- 30296635 TI - The effectiveness of a coordinated preventive care approach for healthy ageing (UHCE) among older persons in five European cities: A pre-post controlled trial. AB - BACKGROUND: Older persons often have multiple health and social problems and need a variety of health services. A coordinated preventive approach that integrates the provision of health and social care services could promote healthy ageing. Such an approach can be organised differently, depending on the availability and organizational structures in the local context. Therefore, it is important to evaluate the effectiveness of a coordinated preventive care approach in various European settings. OBJECTIVES: This study explored the effects of a coordinated preventive health and social care approach on the lifestyle, health and quality of life of community-dwelling older persons in five European cities. DESIGN: International multi-center pre-post controlled trial. SETTING: Community settings in cities in the United Kingdom, Greece, Croatia, the Netherlands and Spain. PARTICIPANTS: 1844 community-dwelling older persons (mean age = 79.5; SD = 5.6). METHODS: The Urban Health Centres Europe (UHCE) approach consisted of a preventive multidimensional health assessment and, if a person was at-risk, coordinated care-pathways targeted at fall risk, appropriate medication use, loneliness and frailty. Intervention and control sites were chosen based on their location in distinct neighbourhoods in the participating cities. Persons in the catchment area of the intervention sites 'the intervention group' received the UHCE approach and persons in catchment areas of the control sites 'the control group' received care as usual. A questionnaire and two measurements were taken at baseline and at one-year follow-up to assess healthy lifestyle, fall risk, appropriate medication use, loneliness level, frailty, level of independence, health-related quality of life and care use. To evaluate differences in outcomes between intervention group and control group for the total study population, for those who received follow-up care-pathways and for each city separately (multilevel) logistic and linear regression analyses were used. RESULTS: Persons in the intervention group had less recurrent falls (OR = 0.65, 95% CI = 0.48; 0.88) and lower frailty (B=-0.43, 95% CI= -0.65 to -0.22) at follow-up compared with persons in the control group. Physical health-related quality of life and mental well-being was better (B = 0.95; 95% CI = 0.14-1.76; and B = 1.50; 95% CI = 0.15-2.84 respectively). The effects of the UHCE approach were stronger in the subgroup of persons (53.6%) enrolled in care-pathways. CONCLUSIONS: Our study found promising but minor effects for the use of a coordinated preventive health and social care approach for the promotion of healthy ageing of older persons. Future studies should further evaluate effects of coordinated preventive health and social care aimed at healthy ageing. TRIAL REGISTRATION: ISRCTN registry number is ISRCTN52788952.

AB - Bacillus cereus is frequently implicated in foodborne outbreaks associated with the consumption of cooked rice. The main contributing factors leading to outbreaks is rice cooked in large quantities and subsequently, inadequately chilled or stored at room temperatures for a prolonged period of time prior to consumption. Bacillus cereus growth in cooked rice inoculated with approximately 2 log CFU/g of heat-shocked (80 degrees C/10 min) spores at several isothermal conditions (between 10 and 49 degrees C) was quantified. B. cereus populations were determined by plating on mannitol egg yolk polymyxin agar and incubating at 30 degrees C for 24 h. Primary growth models, namely Baranyi, Huang, modified Gompertz, and logistic models were fitted to growth data. Specific growth rates from all four primary models were used to fit the modified Ratkowsky square-root model with respect to temperature. All four primary models were well fitted by the modified Ratkowsky model (R2 values from 0.90-0.99). Based on the goodness of fit secondary model statistics (R2, SSE, RMSE), the Baranyi model performed the best and was chosen for tertiary modeling. Acceptable prediction zone (APZ) analysis was performed for validation of the Baranyi model predictions during single rate exponential and biphasic linear cooling temperature profiles. For single rate cooling, 23 of the 24 predictions fell within the APZ (-1.0 to 0.5 log CFU/g). For biphasic linear cooling, 26 of the 28 predictions fell within the APZ. The developed dynamic model can be used to predict potential B. cereus growth from spores in cooked rice during chilling and thus, support the disposition of product subject to cooling deviations. PMID- 30296637 TI - Thermoplastic starch/polybutylene adipate terephthalate film coated with gelatin containing nisin Z and lauric arginate for control of foodborne pathogens associated with chilled and frozen seafood. AB - In order to control foodborne pathogens on seafood products, an antimicrobial, thermoplastic starch/polybutylene adipate terephthalate (TPS/PBAT; 40/60) film was produced by coating gelatin (15% v/v) containing lauric arginate (LAE; 0.8 mg/cm2), alone or combination with nisin Z (69.4 AU/cm2) to produce LAE-Gelatin TPS/PBAT and Nisin-LAE-Gelatin-TPS/PBAT films, respectively. Both films were investigated for control of Vibrio parahaemolyticus ATCC 17802 and Salmonella Typhimurium ATCC 14028 on bigeye snapper (Lutjanus lineolatus) and tiger prawn (Penaeus monodon) slices during long-term (28 days), refrigerated (4 degrees C; chilled) and frozen (-20 degrees C) storage up to 90 days. S. Typhimurium ATCC 14028, experimentally inoculated onto bigeye snapper and tiger prawn slices, treated with the LAE-Gelatin-TPS/PBAT film, and stored at 4 degrees C was reduced 3.2 log10 CFU/g after 28 days and 7 log10 CFU/g after 21 days, respectively. Nisin-LAE-Gelatin-TPS/PBAT film reduced S. Typhimurium ATCC 14028 on bigeye snapper and tiger prawn slices 3.5 log10 CFU/g after 28 days and 7 log10 CFU/g after 14 days at 4 degrees C, respectively. The LAE-Gelatin-TPS/PBAT and Nisin-LAE-Gelatin-TPS/PBAT films and storage for 28 days at 4 degrees C reduced V. parahaemolyticus inoculated on chilled bigeye snapper slices approximately 2.6 and 4.2 log10 CFU/g, respectively. Both films reduced V. parahaemolyticus inoculated on chilled tiger prawn slices approximately 7.1 log10 CFU/g after 28 days at 4 degrees C. The LAE-Gelatin-TPS/PBAT and Nisin-LAE Gelatin-TPS/PBAT films also reduced S. Typhimurium, inoculated on bigeye snapper and tiger prawn slices, 5.8 and 5.6 log10 CFU/g, respectively, after 60 days at 20 degrees C. V. parahaemolyticus was reduced by 5.8 log10 CFU/g on frozen bigeye snapper and tiger prawn slices after treatment with Nisin-LAE-Gelatin TPS/PBAT film after 14 and 21 days, respectively. However, the LAE-Gelatin TPS/PBAT film reduced V. parahaemolyticus 5.8 log10 CFU/g on both frozen seafood slices after 28 days. The results obtained from this study indicate the LAE Gelatin-TPS/PBAT and Nisin-LAE-Gelatin-TPS/PBAT films displayed excellent inhibition against S. Typhimurium and V. parahaemolyticus on chilled and frozen seafood. PMID- 30296638 TI - Treatment of cheese whey by a cross-flow anaerobic membrane bioreactor: Biological and filtration performance. AB - Whey, produced in large quantities during cheese production, is a rapidly fermentable high strength wastewater characterized by a high biodegradability and low alkalinity. In this study, a lab-scale cross-flow anaerobic membrane bioreactor was used to address the commonly experienced difficulties such as unstable reactor performance and unexpected biomass losses when treating whey wastewater with conventional anaerobic reactors. The anaerobic membrane bioreactor provided a stable treatment performance, i.e. more than 90% chemical oxygen demand removal, and moderate membrane fluxes between 8 and 11 L m-2 h-1 could be obtained, applying a low cross-flow velocity of about 0.5 m s-1. Short term critical flux tests revealed that higher fluxes up to 36 L m-2 h-1 are possible at elevated cross-flow velocities and/or reduced mixed liquor suspended solids concentrations. Sludge filterability indicated by capillary suction time and specific resistance to filtration deteriorated throughout the study. Chemical cleaning efficiency gradually decreased, indicating irreversible membrane fouling during long term operation. PMID- 30296639 TI - Placental concentrations of essential, toxic, and understudied metals and relationships with birth outcomes in Chattanooga, TN. AB - BACKGROUND: Comprehensive examinations of placental metal concentrations and correlations with infant parameters are under-investigated. Chattanooga, Tennessee's consistently high incidence of low birth weight and potential for metal exposure provides an ideal opportunity to investigate potential correlations. OBJECTIVES: To investigate the associations between a wide variety of metals in placental tissue and multiple infant parameters. METHODS: A total of 31 elements were screened via ICP-MS in 374 individual placental samples. Of those, 14 were quantifiable in > 86% of the samples. We examined correlations between metal concentrations and infant parameters (birth weight, gestational age, birth weight centile, placental weight, birth length and head circumference). We fit multivariable regression models to estimate the covariate adjusted associations of birth weight with ln-transformed concentrations of each of the 14 metals and used generalized additive models to examine nonlinear relationships. RESULTS: Some of the strongest relationships with infant parameters came from several lesser-studied metals. Placental rhodium concentrations were negatively correlated with almost all infant parameters. In the fully adjusted regression model, birth weight was significantly associated with several metals. On an IQR (25th to the 75th percentile) basis, estimated changes in birthweight were: for cobalt (82.5 g, IQR=6.05 ug/kg, p = 0.006), iron (-51.5 g, IQR = 171800 ug/kg, p = 0.030), manganese (-27.2 g, IQR=152.1 ug/kg, p = 0.017), lead (-72.7 g, IQR=16.55 ug/kg, p = 0.004) and rhodium (-1365.5 g, IQR = 0.33 ug/kg, p < 0.001). Finally, a generalized additive model showed significant nonlinear relationships between birth weight and concentrations of Co and Rh. CONCLUSIONS: Our comprehensive examination of placental metals illustrate many strong associations between lesser-studied metals and infant parameters. These data, in combination with our correlations of well-studied metals, illustrate a need to consider in utero exposure to a broad array of metals when considering fetal development. PMID- 30296640 TI - The tubercular badger and the uncertain curve:- The need for a multiple stressor approach in environmental radiation protection. AB - This article presents the results of a workshop held in Stirling, Scotland in June 2018, called to examine critically the effects of low-dose ionising radiation on the ecosphere. The meeting brought together participants from the fields of low- and high-dose radiobiology and those working in radioecology to discuss the effects that low doses of radiation have on non-human biota. In particular, the shape of the low-dose response relationship and the extent to which the effects of low-dose and chronic exposure may be predicted from high dose rate exposures were discussed. It was concluded that high dose effects were not predictive of low dose effects. It followed that the tools presently available were deemed insufficient to reliably predict risk of low dose exposures in ecosystems. The workshop participants agreed on three major recommendations for a path forward. First, as treating radiation as a single or unique stressor was considered insufficient, the development of a multidisciplinary approach is suggested to address key concerns about multiple stressors in the ecosphere. Second, agreed definitions are needed to deal with the multiplicity of factors determining outcome to low dose exposures as a term can have different meanings in different disciplines. Third, appropriate tools need to be developed to deal with the different time, space and organisation level scales. These recommendations permit a more accurate picture of prospective risks. PMID- 30296641 TI - A comparison of figure of merit (FOM) for various materials in adsorptive removal of benzene under ambient temperature and pressure. AB - To effectively remove gaseous pollutants from air using sorbents, a thorough knowledge of the actual sorption performance is needed at ambient conditions rather than at unrealistically high-pressure conditions, as is commonly presented in the literature. To this end, the sorbent capacities of gaseous benzene were evaluated at a constant sorbent bed inlet pressure (50 ppm or ~5 Pa) in 1 atm of N2, room temperature (298 K), a fixed flow rate (50 mL min-1), and equal outlet sampling intervals (5 min). The benzene adsorption patterns were investigated against six sorbent types in a total of 17 different forms: 1- zeolite in five forms: beads (ZB), ground to 212 um (ZG212), beads ground to 300 um (ZG300), coarsely ground/washed zeolite (ZWc), and coarsely ground/washed/thermally treated zeolite (ZTc), 2- activated carbon in two forms: 212 um (ACd212) and granular (ACdg), 3- Carbopack-X (CX), 4- Tenax TA (TA), 5- used black tea leaves of 150 or 300 um in three forms: dry (TD150/TD300), wet (TW150/TW300), and wet dust (TWd), and 6- used ground coffee in either dry (CD) or wet forms (CW). Accordingly, the largest adsorption capacities at 5 Pa (e.g., >10 mg g-1) were observed for ACd212 (79.1) and ACdg (73.6). Moderate values (e.g., 5 < < 10 mg g 1) were obtained for ZG212 (7.98), CX (6.79), ZG300 (5.70), and ZB (5.58), while the remainder were far lower at < 5 mg g-1 (e.g., tea leaves, ground coffee, TA, ZWc, and ZTc). The experimental benzene capacities of the tested sorbents were further assessed by the Langmuir, Henry's law, Freundlich, Dubinin-Radushkevich, and Elovich isotherm models. The linearized Langmuir adsorption isotherms of ACd212, ACdg, and CX showed the presence of more than one adsorption site (i.e., retrograde at the lowest pressures and two others at higher pressures). However, TA, zeolite, tea leaves, and ground coffee exhibited a type-V isotherm, wherein the sorption capacity continued to increase with loaded volume (i.e., multilayer adsorption). Thus, ACd212 has the best figure-of-merit based on a high 10% breakthrough volume (BTV) and low cost for real-world applications. PMID- 30296642 TI - Structure of a lytic polysaccharide monooxygenase from Aspergillus fumigatus and an engineered thermostable variant. AB - Lytic polysaccharide monooxygenases (LPMOs) are industrial enzymes which are gaining use in second generation bioethanol production from lignocellulose by acting in synergy with glycoside hydrolases. Here we present the X-ray crystal structure of an AA9 fungal LPMO from Aspergillus fumigatus and a variant which has been shown to have better performance at elevated temperatures. Based on the structures, thermal denaturation data and theoretical calculations, we provide a suggestion for the structural basis of the improved stability. PMID- 30296643 TI - Selectivity of original C-hexopyranosyl calix[4]arene conjugates towards lectins of different origin. AB - As a part of ongoing activities towards the design of ligands against pathogenic lectins, a synthesis of original alpha-C-galacto/alpha-C-manno/alpha-C fucopyranosyl glycomimetics based on a calix[4]arene scaffold and their binding evaluation is described. The interactions of the glycomimetics with seven lectins of various origins were carried out using agglutination inhibition assays. The 1,3-alternate tetra-C-fucosylated ligand and its derivative having a tertBu group at the upper rim of the calix[4]arene scaffold were the most potent towards the AAL lectin family (RSL, AFL, AAL, AOL) and BC2L-C. As AFL and RSL originate from important human (Aspergillus fumigatus) and plant (Ralstonia solanacearum) pathogens, the inhibition potency of both leading structures was assessed by surface plasmon resonance. With AFL, both structures exhibited an approximately three orders of magnitude increase in affinity compared to the reference l fucose. The role of tertBu groups as "aglycon-assisted" events was illustrated by NMR. Furthermore, both compounds showed significantly increased ability to inhibit BC2L-C (from human pathogen Burkholderia cenocepacia) cell agglutination and were able to cross-link whole B. cenocepacia cells. Although the ligands failed to significantly inhibit the agglutination activity of LecA and LecB from Pseudomonas aeruginosa, tetra-C-galactosylated calix[4]arene with tertBu groups at the upper rim of the 1,3-alternate conformation inhibited P. aeruginosa biofilm formation efficiently. This systematic and comprehensive study highlights the fact that hydrolytically stable polyvalent C-glycomimetics should be regarded as potent and selective ligands capable of acting as antiadhesive agents. PMID- 30296644 TI - Co-morbidity with hypertrophic osteoarthropathy: A possible Iron Age Sarmatian case from the Volga steppe of Russia. AB - PURPOSE: Hypertrophic osteoarthropathy (HOA) is a condition that can be inherited or acquired. It causes diffuse periosteal new bone formation on the long bones, with a predilection for the appendicular skeleton. When acquired, it is a nonspecific indicator of systemic disease that arises following a primary condition. This paper reviews the palaeopathological literature associated with this rare condition. It also describes the first possible case of co-morbidity associated with hypertrophic osteoarthropathy in an adult skeleton (cal. BC 170 - 1 cal. AD) from the mobile pastoralist Sarmatian culture of the Volga steppes of Russia. METHODS: Macroscopic and radiological examination provide differential diagnoses of the lesions, while clinical and bioarchaeological analyses offer insights into the possible experience of disease and social implications of care among the nomadic populations of Iron Age Russia. RESULTS: The analysis of Sk. 6524.102 displays lesions that may be due to both hypertrophic osteoarthropathy and osteomalacia. The man was physically impaired and his participation in physically challenging activities would have been limited. CONCLUSIONS: The study stresses that co-morbidity is a key parameter when interpreting disease in past populations, particularly when the diagnosis involves hypertrophic osteoarthropathy. SIGNIFICANCE: This is the first case of hypertrophic osteoarthropathy identified in Eurasian prehistoric populations. The research emphasises the significance of co-morbidity in the past. LIMITATIONS: The diagnosis of co-morbid diseases in human remains is extremely complex and the conditions were identified as most probable by a process of elimination. SUGGESTIONS FOR FURTHER RESEARCH: Further studies should be dedicated to understanding co-morbidity in the past. PMID- 30296645 TI - A comparison among beta-caseins purified from milk of different species: Self assembling behaviour and immunogenicity potential. AB - Caseins are a family of proteins constituted by alpha-caseins (alphas-1 and alphas-2 caseins), beta-caseins and kappa-caseins. beta-caseins, in particular, show a temperature and concentration-dependent self-assembling behaviour. Recently, beta-casein micelles have been proposed as natural nanocarriers for the delivery of hydrophobic compounds, promoting their bioavailability. Until now, all studies regarding both chemical-physical characterization and applications of beta-caseins have employed the protein of bovine origin. However, it could be interesting to exploit the use of beta-caseins from other milk sources for their potential encapsulation ability and immunogenicity but, at present, no information on the self-assembling behaviour is available for beta-caseins from the milk of species different from bovine. In this work, for the first time, beta caseins from human milk and from donkey, goat, and sheep milk were purified and their self-assembling behaviour was compared to that of a commercial bovine beta casein, the only one for which the concentration and temperature aggregation behaviour is known. Furthermore, a preliminary evaluation of the immunogenicity potential of beta-casein from other milk sources has been performed by cross reaction experiments using anti-beta-casein antibodies from bovine origin. The results indicated a similar self-assembling profile among all beta-caseins examined compared to the bovine beta-casein, suggesting the possible use of beta casein from other milk sources as nanocarriers. Since donkey and human beta casein do not cross-react with bovine anti-beta-casein antibodies, they could be particularly interesting for the development of self-assembling systems with lower hypoallergenic potential. PMID- 30296646 TI - In situ phase transition of microemulsions for parenteral injection yielding lyotropic liquid crystalline carriers of the antitumor drug bufalin. AB - In this work, we used the small angle X-ray scattering (SAXS) method for controlled preparation of in situ forming sustained-release carriers for the antitumor drug bufalin (BUF), which has very poor solubility and a considerable cardiotoxicity in a non-encapsulated state. To that aim, we exploited the pseudo ternary phase diagram of an oil(O)/surfactant(S)/water(W) system containing medium chain capric/caprylic triglycerides (MCT) and a co-surfactant blend of Macrogol (15)-hydroxystearate (Solutol HS 15) and sorbitan monooleate (Span 80). Two compositions with different oil contents (sample B and C) were selected from the microemulsion region of the phase diagram in order to study the effect of the aqueous environment on their structural behavior. A phase transition from a microemulsion (ME) to a liquid crystalline phase (LC) was established by SAXS upon progressive dilution. The drug bufalin (BUF) was encapsulated in the microemulsions with low viscosity, whereas the release of the drug occurred from the in situ generated lamellar liquid crystalline structures. The formulations were characterized by SAXS, dynamic light scattering (DLS), cryogenic transmission electron microscopy (Cryo-TEM), rheology, drug loading and encapsulation efficiency, and in vitro release profiles. A correlation was suggested between the structures of the in situ phase-transition formed LCME formulations, the differences in their viscosities and drug release profiles. The performed cytotoxicity, cell apoptosis and pharmacokinetic experiments showed an enhanced bioavailability of BUF after encapsulation. These results suggest potential clinical applications for the obtained safe in situ phase-transition sustained-release formulations of BUF. PMID- 30296647 TI - Trace element concentrations in breast cancer patients. AB - Alterations in the circulating levels of trace elements have been observed in breast cancer (BC) patients. However, the relationships between these alterations and the metabolic and clinical consequences of BC are unknown. The treatment-of choice of BC is surgery followed by radiation therapy (RT). The present study was aimed at investigating: 1) the concentrations of several trace elements in BC patients, and their relationships with the intrinsic molecular subtypes of tumors; 2) the toxicological effect of RT. We studied 49 women with BC who were scheduled to receive RT following excision of the tumor. Plasma samples were obtained before and after the irradiation procedure. The control group was composed of 49 healthy women. Patients had significantly lower pre-RT concentrations of B, Cu, and Zn, and significantly higher concentrations of Sr than the control group. Irradiation was associated with a striking increase in plasma B concentrations, while Cu, Fe, Sr and Zn concentrations were not significantly different from pre-RT levels, albeit Sr and Zn showed non significant trends towards increases. The plasma concentrations of B, Cu, Fe, Sr, and Zn were associated with the tumor expression of hormone receptors, epidermal growth factor receptor 2, Ki67 antigen, as well as dermatitis and asthenia, all of which represent the main toxicological responses to RT. PMID- 30296648 TI - Treatment outcomes of breast cancer liver metastasis treated with stereotactic body radiotherapy. AB - BACKGROUND: To assess the outcomes of breast cancer liver metastasis (BCLM) treated with stereotactic body radiotherapy (SBRT) and systemic treatment. MATERIALS AND METHODS: Patients with oligometastasis at the time of liver metastasis (LM) or who became oligometastatic (<=5 metastases) after systemic treatment were assessed. Twenty-nine liver metastatic lesions were treated with a total of 54 Gy delivered in 3 fractions. The local control (LC), overall survival (OS), and progression-free survival (PFS) rates were calculated using Kaplan Meier analyses. RESULTS: A total of 22 patients with 29 liver metastatic lesions treated with liver SBRT between April 2013 and September 2017 were retrospectively analyzed. After a median follow-up time of 16.0 months (range 4.4 59.4 months), 18 patients (82%) had disease recurrence, median of 7.4 months (range 1.0-27.9 months) after completion of liver SBRT. The 1- and 2-year OS rates were 85% and 57%, and the 1- and 2-year PFS rates were 38% and 8%, respectively. The 1- and 2-year LC rates were 100% and 88%, respectively. No significant prognostic factors, including disease extension, size of metastasis, number of liver metastasis and timing of liver metastasis, hormonal status affecting OS, PFS and LC were found. No patients experienced Grade 4 or 5 toxicity; furthermore, only one patient experienced rib fracture 6 months after completion of treatment, and one patient had a duodenal ulcer. CONCLUSION: This study is the first to evaluate the feasibility of SBRT to BCLM patients. Liver SBRT is a conservative approach with excellent LC and limited toxicities. PMID- 30296649 TI - Harm-reduction and zero-tolerance maternal messages about college alcohol use. AB - Past cross-sectional research suggests that zero-tolerance messaging by parents of college students may be more effective than harm-reduction communication at reducing student alcohol risk. The current study employs longitudinal data to examine whether communication type interacts with student alcohol use to predict subsequent drinking outcomes. U.S. college students reported on their own exposure to zero-tolerance and harm-reduction maternal communication. Approximately seven months later, students completed measures of maternal alcohol approval and their own alcohol behaviors. The relationship between communication and subsequent alcohol behaviors depended on students' baseline drinking. For heavy drinkers, harm-reduction communication was associated with less alcohol use and consequences. For those who drank less than two drinks a week, zero-tolerance communication was associated with fewer negative consequences. Zero-tolerance communication was associated with perceiving mothers as less approving, while harm reduction communication was associated with perceiving mothers as more approving. There were indirect effects of communication on drinking through perceived maternal approval. While overall harm-reduction communication may lead students to perceive mothers as more approving of alcohol use, there may be contexts in which this type of communication is beneficial. PMID- 30296650 TI - Evaluation of SexedULTRA 4MTM sex-sorted semen in timed artificial insemination programs for mature beef cows. AB - An experiment was designed to compare fertility of SexedULTRA 4MTM sex-sorted semen and conventional, non-sex-sorted semen following either fixed-time artificial insemination (FTAI) or split-time artificial insemination (STAI) of mature suckled beef cows. Units of sex-sorted and conventional semen were produced using contemporaneous ejaculates from three commercially available sires. Units of conventional semen were generated with 25.0 * 106 live cells per 0.25 ml straw prior to freezing, and units of sex-sorted semen were generated using the SexedULTRATM Genesis III sorting technology with 4.0 * 106 live cells per 0.25 ml straw prior to freezing. Sex-sorted units were sorted to contain X chromosome-bearing sperm cells at an accuracy level of >90%. Cows (n = 1620) across four herds were treated with the 7-d CO-Synch + CIDR protocol [administration of gonadotropin-releasing hormone (GnRH) and insertion of a progesterone insert (CIDR) on Day -10, followed by administration of prostaglandin F2alpha (PG) and removal of CIDR inserts on Day -3]. Cows were preassigned based on age, body condition score, and days postpartum to one of the following four treatments: FTAI with SexedULTRA 4MTM sex-sorted semen, FTAI with conventional semen, STAI with SexedULTRA 4MTM sex-sorted semen, or STAI with conventional semen. On Day -3, estrus detection aids (Estrotect(r)) were applied. For cows in FTAI treatments, AI was performed on Day 0 at 66 h after PG administration and CIDR removal, and 100 MUg GnRH was administered concurrent with AI. For cows in STAI treatments, AI was performed on either Day 0 or 1, at 66 or 90 h after PG administration and CIDR removal, based on timing of estrus expression. On Day 1 at 90 h after PG administration and CIDR removal, 100 MUg GnRH was administered concurrent with AI to any STAI-treated cows that had failed to express estrus. Pregnancy rates to AI were affected (P = 0.04) by the interaction of bull and semen type. Greater pregnancy rates were obtained with conventional semen versus SexedULTRA 4MTM sex-sorted semen when using semen from Bull A (64% [176/277] versus 36% [100/278]; P < 0.0001) and Bull B (72% [200/277] versus 57% [156/276]; P < 0.01), whereas pregnancy rates to AI did not differ between conventional and SexedULTRA 4MTM sex-sorted semen when using semen from Bull C (58% [149/258] versus 52% [131/254]). Pregnancy rates did not differ significantly between cows inseminated using a STAI versus FTAI approach, regardless of whether insemination was performed with conventional semen (65% [265/409] versus 65% [260/403] or SexedULTRA 4MTM sex-sorted semen (50% [200/403] versus 48% [187/405]). However, due to the additional 24 h for potential estrus expression when performing STAI, total estrous response prior to AI was greater (P < 0.001) among cows receiving STAI (84%; 686/812) compared to FTAI (72%; 585/808), and greater pregnancy rates (P < 0.0001) were obtained among cows that expressed estrus prior to AI. In summary, the relative fertility of SexedULTRA 4MTM sex-sorted semen and conventional semen varied across bulls. Although overall pregnancy rates to timed AI did not differ between STAI and FTAI approaches, use of a STAI approach allowed for greater total estrous response prior to AI. Therefore, to achieve acceptable conception rates per unit and service the maximum number of cows with sex-sorted semen, one viable approach may be to use STAI to maximize total estrous response and restrict use of SexedULTRA 4MTM sex-sorted to only those cows expressing estrus.

AB - The biological function of inhibin is mediated by two heterodimers, inhibin-A and inhibin-B. The relative importance of inhibin-A and -B in male reproductive function varies considerably across species with inhibin-B predominating in many species, whereas inhibin-A appears relatively more important in rams. Research reported to date in stallions has examined total or immunoreactive (ir) inhibin which does not distinguish the two heterodimers. Therefore, the objective of this study was to characterize changes in inhibin-A and inhibin-B concentrations in stallions: 1) across season for a period of one year, and 2) after downregulation of the hypothalamic-pituitary-gonadal (HPG) axis. In Study one, serum samples were obtained monthly from five stallions for a period of one year. Serum concentrations of inhibin-A, inhibin-B, testosterone and estrone sulfate were determined by ELISA. In Study two, stallions were treated with the GnRH antagonist, acyline (n = 4; 330 mg/kg acyline IM) or vehicle control (n = 4; vehicle alone) every five days for 50 days. Plasma concentrations of inhibin-A and -B were determined by ELISA at Days 0, 6, 12, 22, 37, 59, 80, 87 and 104 after initiation of acyline treatment. Testis volume was determined by ultrasonography at weekly intervals. In Study 1, both inhibin-A and inhibin-B showed seasonal changes in concentration with highest concentrations in increasing day length and lowest concentrations in short day lengths. Inhibin-B (overall mean 107.8 +/- 4.1 pg/mL) was present at 4.7-fold higher concentrations in serum than inhibin-A (overall mean 23.0 +/- 0.7 pg/mL). In Study 2, plasma concentrations of inhibin-B but not inhibin-A were significantly downregulated by administration of the GnRH antagonist, acyline. When the HPG axis was downregulated by acyline, testis volume was strongly correlated with inhibin-B (r = 0.73; P < 0.05) but not inhibin-A (r = 0.22; P = 0.20). In summary, inhibin-B appears to be the predominant form of inhibin in the stallion which undergoes seasonal regulation along with other reproductive parameters and is co-regulated with other endocrine parameters of the HPG axis.

AB - Equine chorionic gonadotropin (eCG) has been commonly used to induce estrus in several felid species. However, the mechanisms by which this gonadotropin regulates cat folliculogenesis are still unclear. We investigated the responsiveness of cat ovarian follicles at different developmental stages to various eCG concentrations supplemented in vitro. Follicles were mechanically isolated from the ovaries of 22 cats and categorized into three developmental stages based on their morphology and diameter: 1) two-layered secondary follicle (SF), 100-150 MUm (n = 139); 2) multi-layered SF, 150-300 MUm (n = 154); and 3) early antral follicle (AF), >=300-500 MUm (n = 123). The follicles were then encapsulated in 0.5% (w/v) sodium alginate and cultured for 12 days in Minimum Essential Medium supplemented with 0, 0.05, 0.1 or 0.5 IU/mL eCG. Follicle and oocyte diameters were assessed every 3 days. On Day 12, mRNA expression levels of FHSR, LHCGR, GDF9, BMP15, CYP17A1, CYP19A1 and STAR were analyzed using real-time PCR. After being cultured for 12 days, follicle growth and mRNA expression of two layered SF were not influenced by eCG at all concentrations (P > 0.05). However, the concentration of eCG at 0.05 IU/mL stimulated follicular growth and gene expressions in the multi-layered SF and early AF (P < 0.05). Correspondingly, the diameter of oocytes in the multi-layered SF and early AF treated with 0.05 IU/mL eCG was unchanged. Considering the mRNA expression, the level of STAR was enhanced in the early AF (P < 0.05) and tended to increase in the multi-layered SF (P = 0.08) cultured in 0.05 IU/mL eCG, whereas the expression of other genes was not affected. In sum, the responsiveness of cat follicles to eCG is apparent from the multi-layered SF stage onward. The eCG supplementation at 0.05 IU/mL appeared to be optimal for the follicle culture in the domestic cats. PMID- 30296653 TI - Testosterone-retinoic acid signaling directs spermatogonial differentiation and seasonal spermatogenesis in the Plateau pika (Ochotona curzoniae). AB - During evolution, animals optimize their reproductive strategies to increase offspring survival. Seasonal breeders reproduce only during certain times of the year. In mammals, reproduction is tightly controlled by hypothalamus-pituitary gonad axis. Although pathways regulating gametogenesis in non-seasonal model species have been well established, molecular insights into seasonal reproduction are severely limited. Using the Plateau pika (Ochotona curzoniae), a small rodent animal species native to the Qinghai-Tibetan plateau, as a model, here we report that seasonal spermatogenesis is governed at the level of spermatogonial differentiation. In testis of the reproductively dormant animals, undifferentiated spermatogonia failed to differentiate and accumulated in the seminiferous tubules. RNA-seq analyses of the active and dormant testes revealed that genes modulating retinoic acid biogenesis and steriodogenesis were differentially regulated. A single injection of all-trans retinoic acid (ATRA) reinitiated spermatogenesis and inhibition the function of RA-degrading enzyme CYP26B1 for 10 days induced spermatogonial differentiation. Strikingly, testosterone injection reinitiated spermatogenesis in short day adapted animals. Testosterone provides a permissive environment of RA biogenesis and actions in testis, therefore, indirectly controls spermatogonial differentiation. Collectively, these findings provide a key mechanistic insight regarding the molecular regulation of seasonal reproduction in mammals. PMID- 30296654 TI - Evaluation of immunophenotyping, proliferation and osteogenic differentiation potential of SSEA-4 positive stem cells derived from pulp of deciduous teeth. AB - OBJECTIVES: Despite the increased interest in stem cells isolated from remnant pulp of deciduous teeth, no specific marker has been yet established for them. The present study aimed to investigate whether SSEA-4 (stage-specific embryonic antigen) would be a suitable marker to isolate stem cells from Human Exfoliated Deciduous teeth (SHEDs) in order to increase its differentiation potential toward osseous tissue. DESIGN: The SHEDs were isolated and the expression patterns of mesenchymal, hematopoietic and embryonic stem cell markers were assessed. The cells were then divided into two groups of SSEA-4(+) and unsorted SHEDs and the cell proliferation rate and population-doubling-time (PDT) were calculated. Subsequently, the differentiation potentials were examined through alizarin-red staining and Quantitative real time-PCR (qRT-PCR). RESULTS: Isolated cells were spindle-shaped with a high expression of mesenchymal stem cell markers and weak expression of hematopoietic markers. The mean expression of Oct-4 was 68.77%+/ 1.28. Despite similar proliferation rates between SSEA-4(+) and unsorted SHEDs, because of differences in the shape of the growth curves, PDT was lower in unsorted SHEDs (P = 0.2 * 10-4). Alizarin-red staining showed similar calcium deposition in both groups. Upon differentiation, the expression of osteocalcin was higher in unsorted SHEDs (P = 0.043), while, the expression of alkaline phosphatase was lower (P<0.001). The parathyroid hormone receptor (PTHR) expression was not significantly different (P = 0.0625). CONCLUSIONS: The results of the present study revealed that SHEDs have high differentiation potentials even in the unsorted cells. Although the SSEA-4-positive SHEDs showed slightly better osteogenic potential, the differences were not abundant to link SSEA-4 expression with superior differentiation potency. PMID- 30296655 TI - Chemical composition of Pistacia vera L. oleoresin and its antibacterial, anti virulence and anti-biofilm activities against oral streptococci, including Streptococcus mutans. AB - OBJECTIVE: The aim of this study was to characterize the chemical composition of oleoresin of Pistacia vera L. and to determine its antimicrobial and anti virulence activity versus selected oral streptococci. DESIGN: A gaschromatografic analysis of the oleoresin was performed. The antimicrobial and anti-virulence activity of the oleoresin and its fractions was evaluated by the Minimum Inhibitory Concentration (MIC) and/or Minimum Bactericidal Concentration (MBC), biofilm production and haemolytic activity inhibition experiments. RESULTS: The oleoresin MBCs were >=1024 MUg/mL for all tested strains; the neutral and acidic fraction MBCs ranged from 128 to 2048 MUg/mL. Essential oil's MBCs (from 256 to 2048 MUg/mL) were almost identical to MICs, suggesting a bactericidal effect. P. vera oleoresin at sub-lethal concentrations significantly reduced biofilm production by Streptococcus mutans (up to 49.4%) and by Streptococcus sanguinis (up to 71.2%). In addition, the acidic fraction showed a specific anti-biofilm activity against S. mutans (up to 41.3% reduction). A significant dose-dependent reduction in the haemolytic activity of S. mutans (up to 65.9%) and of S. anginosus (up to 78.3%) was observed after growth in the presence of oleoresin at sub-lethal concentrations. The acidic fraction reduced haemolytic activity (up to 54.3% at 64 MUg/mL) of S. mutans only. CONCLUSIONS: Given the anti-virulence activity of the P. vera oleoresin and its acidic fraction against S. mutans, our findings suggest their potential use in oral hygiene. These data represent the first step in the exploitation of P. vera L. oleoresin. PMID- 30296656 TI - Investigation of flow dynamics of phosphate fertilizer production reactors using radiotracer technique. AB - Radiotracer investigations were carried out in two identical phosphoric acid production reactors and a triple super phosphate (TSP) production reactor in three different plants in Tunisia. The main objective of the study was to investigate and compare their flow behavior and identify flow abnormalities, if any. Residence time distribution (RTD) of the process material (ore pulp) was measured in the three reactors using Iodine-131. The measured RTDs were treated and analyzed to obtain flow parameters such as the mean residence time (MRT), dead volume, and extent of bypassing. The treated RTD curves were modeled using a suitable mathematical model, and the values of the parameters were obtained. The results of the investigations were used to evaluate and compare the flow performance of the reactors, quantify the degree of mixing, and visualize the prevailing flow patterns. The results of the investigations are expected to be used to make necessary modifications to enhance the efficiency and optimize the performance of the reactors or the production process. PMID- 30296657 TI - Time-Integrative Passive sampling combined with TOxicity Profiling (TIPTOP): an effect-based strategy for cost-effective chemical water quality assessment. AB - This study aimed at demonstrating that effect-based monitoring with passive sampling followed by toxicity profiling is more protective and cost-effective than the current chemical water quality assessment strategy consisting of compound-by-compound chemical analysis of selected substances in grab samples. Passive samplers were deployed in the Dutch river delta and in WWTP effluents. Their extracts were tested in a battery of bioassays and chemically analyzed to obtain toxicity and chemical profiles, respectively. Chemical concentrations in water were retrieved from publicly available databases. Seven different strategies were used to interpret the chemical and toxicity profiles in terms of ecological risk. They all indicated that the river sampling locations were relatively clean. Chemical-based monitoring resulted for many substances in measurements below detection limit and could only explain <20% of the observed in vitro toxicity. Effect-based monitoring yielded more informative conclusions as it allowed for ranking the sampling sites and for estimating a margin-of-exposure towards chronic effect ranges. Effect-based monitoring was also cheaper and more cost-effective (i.e. yielding more information per euro spent). Based on its identified strengths, weaknesses, opportunities, and threats (SWOT), a future strategy for effect-based monitoring has been proposed. PMID- 30296659 TI - Metaphors we learn by: Directed motor action improves word learning. AB - Can performing simple motor actions help people learn the meanings of words? Here we show that placing vocabulary flashcards in particular locations after studying them helps students learn the definitions of novel words with positive or negative emotional valence. After studying each card, participants placed it on one of two shelves (top or bottom), according to its valence. Participants who were instructed to place positive cards on the top shelf and negative cards on the bottom shelf, consistent with metaphors that link "good" with "up," remembered the words' definitions better than participants who followed the opposite spatial mapping, and better than control participants who placed all of the cards on the desktop. Saying "up" and "down" after studying the cards was ineffective, suggesting a privileged role for motor action in activating space valence associations that partly constitute the meanings of emotionally charged words. These results provide a first demonstration that mental metaphors can be activated strategically to improve (or impair) word learning: We call this the strategic use of mental metaphor (SUMM) effect. Even when multiple factors known to enhance encoding of verbal materials into long-term memory were matched across conditions (e.g., study time, repetition, distinctiveness, depth of processing), metaphor-congruent motor actions led to better elaborated, more durable memories. PMID- 30296658 TI - The Evolutionarily Conserved Cassette Exon 7b Drives ERG's Oncogenic Properties. AB - The oncogene ERG encodes an ETS family transcription factor and is implicated in blood, vascular, and bone development and in prostate, blood, and bone cancer. The ERG gene is alternatively spliced; of particular interest is its cassette exon 7b which adds 24 amino acids, in frame, to the transcriptional activation domain. Higher exon 7b inclusion rates are associated with increased cell proliferation and advanced prostate cancer. The 24 amino acids encoded by exon 7b show evolutionary conservation from humans to echinoderms, highlighting their functional importance. Throughout evolution, these 24 amino acids are encoded by a distinct short exon. Splice-switching oligonucleotides based on morpholino chemistry were designed to induce skipping of ERG exon 7b in MG63 osteosarcoma and VCaP prostate cancer cells. Induction of exon 7b skipping reduced cell proliferation and invasion, increased apoptosis in vitro, and reduced xenograft growth in vivo. We also show that ERG's exon 7b is required for the induction of tissue nonspecific alkaline phosphatase. Together, these findings show that the evolutionarily conserved cassette exon 7b is central to ERG's oncogenic properties. PMID- 30296660 TI - Development of the sea urchin Heliocidaris crassispina from Hong Kong is robust to ocean acidification and copper contamination. AB - Metallic pollution is of particular concern in coastal cities. In the Asian megacity of Hong Kong, despite water qualities have improved over the past decade, some local zones are still particularly affected and could represent sinks for remobilization of labile toxic species such as copper. Ocean acidification is expected to increase the fraction of the most toxic form of copper (Cu2+) by 2.3-folds by 2100 (pH ~7.7), increasing its bioavailability to marine organisms. Additionally, multiple stressors are likely to exert concomitant effects (additive, synergic or antagonist) on the organisms living in the sea. Here, we tested the hypothesis that copper-contaminated waters are more toxic to sea urchin larvae under future pH conditions. We exposed sea urchin embryos and larvae to two low-pH and two copper treatments (0.1 and 1.0 MUM) in three separate experiments. Over the short time typically used for toxicity tests (up to 4-arm plutei, i.e. 3 days), larvae of the sea urchin Heliocidaris crassispina were robust and survived the copper levels present in Hong Kong waters today (<=0.19 MUM) as well as the average pH projected for 2100. We, however, observed significant mortality with lowering pH in the longer, single stressor experiment (Expt A: 8-arm plutei, i.e. 9 days). Abnormality and arm asymmetry were significantly increased by pH or/and by copper presence (depending on the experiment and copper level). Body size (d3; but not body growth rates in Expt A) was significantly reduced by both lowered pH and added copper. Larval respiration (Expt A) was doubled by a decrease at pHT from 8.0 to 7.3 on d6. In Expt B1.0 and B0.1, larval morphology (relative arm lengths and stomach volume) were affected by at least one of the two investigated factors. Although the larvae appeared robust, these sub-lethal effects may have indirect consequences on feeding, swimming and ultimately survival. The complex relationship between pH and metal speciation/uptake is not well-characterized and further investigations are urgently needed to detangle the mechanisms involved and to identify possible caveats in routinely used toxicity tests.

PMID- 30296662 TI - Innate immunosensing of DNA in cellular senescence. AB - Senescence is a multistep cellular program featuring a stable cell cycle arrest, which occurs upon exposure to various stressors. Senescent cells exhibit metabolic activity and hypertrophy and produce a multitude of factors with both cell intrinsic as well as non-cell autonomous functions. These factors are collectively referred to as the senescence-associated secretory phenotype (SASP). Recently, the DNA sensor cyclic GMP AMP synthase (cGAS) and the adaptor stimulator of interferon genes (STING) have been reported to be critically involved in the regulation of senescence. This suggests that cGAS has an important function as a more general cell intrinsic stress sensor with implications for multiple senescence-associated diseases. PMID- 30296663 TI - Diet and physical activity in the association between depression and metabolic syndrome: Constances study. AB - BACKGROUND: The association between depression and the metabolic syndrome remains poorly understood. Diet and physical activity may partly explain this association. METHODS: Baseline data on 64,861 subjects from the French population based Constances cohort was analyzed. Depressive symptoms were determined with the Center of Epidemiologic Studies Depression (CES-D) scale. A CES-D score >= 19 combined with self-reported limitations related to depressive symptoms was used to define depression. The metabolic syndrome was defined according to the International Diabetes Federation criteria. Dietary patterns were determined with a food frequency questionnaire and a principal component analysis. Physical activity was measured with 3 questions resulting in a composite 6-point scale. Associations between depression and the metabolic syndrome were estimated through logistic regression and path analysis. RESULTS: The odds-ratios (95% confidence interval) for the association between depression and the metabolic syndrome, adjusting for age, sex, education and income, was 1.75 (1.57-1.96). The path analysis showed that 23% of this association was explained by diet and physical activity, 67% being attributed to physical activity. LIMITATIONS: The cross sectional nature of the analyses warrants the results to be confirmed by longitudinal analyses. CONCLUSION: Diet and physical activity might partially explain the association between depressive symptoms and metabolic syndrome but other factors (e.g. inflammatory factors) are involved. PMID- 30296664 TI - Transient epileptic and global amnesia: Real-life differential diagnosis. AB - OBJECTIVE: Transient epileptic amnesia (TEA) is an underestimated condition in emergency clinical setting, where most of transient amnesic episodes tend to be classified as transient global amnesia (TGA). We designed this study to evaluate the actual frequency of TEA in a real-life scenario and to highlight the features that can help clinicians distinguishing it from TGA. METHODS: We retrospectively collected clinical data of 83 patients who accessed our emergency ward for an abrupt onset of amnesic disorder, initially interpreted as TGA. All patients underwent neurological evaluation, magnetic resonance imaging (MRI) scan, and standard 21-channel scalp electroencephalography (EEG) recording (standard EEG [st-EEG]). Moreover, patients with borderline epileptiform abnormalities on st EEG or with normal st-EEG but high clinical suspicion for TEA underwent a 16 channel 24-hour ambulatory EEG (24-h EEG). Clinical features, neurophysiological, and neuroimaging data were analyzed and compared in the two groups (TEA and TGA). RESULTS: Diagnosis of TEA, according to Zeman's criteria, was made in 15 patients (18%). From a clinical point of view recurrence (p < .001) and atypical symptoms such as confusion or language disorder (TGA plus manifestations), appear to be key elements in order to discriminate between TEA and TGA (80% of patients with TEA vs 7.8% of patients with TGA; p < .001). In our sample, duration of the episodes did not significantly differ between TGA and TEA, even though it is usually described as shorter for TEA. This result could be related with a prolonged postictal state in these patients. The analysis of st-EEG results evidenced low sensitivity for interictal epileptiform abnormalities (IEAs) detection (52.3%), with not conclusive data in distinguishing TEA from TGA. On the contrary, 24-h EEG showed IEAs in all patients with epilepsy, mostly during sleep, suggesting an essential diagnostic role of long-lasting EEG recording for TEA. Finally, structural abnormalities were more frequent in patients with TEA (26.6%). In the group with TGA, the only imaging alteration found was diffusion weighted imaging (DWI) hippocampal hyperintensity. CONCLUSION: Our findings show that in a real-life clinical scenario, TEA is frequent but often overlooked. However, simple clinical data and widely available neurophysiological examinations can truly help to effectively distinguish TEA from TGA. PMID- 30296665 TI - A comparison of levetiracetam and phenobarbital for the treatment of neonatal seizures associated with hypoxic-ischemic encephalopathy. AB - PURPOSE: Seizures are common in term infants with hypoxic-ischemic encephalopathy (HIE) undergoing therapeutic hypothermia. Although phenobarbital (PHB) is generally considered first-line therapy, some centers have embraced third generation antiepileptic drugs (AEDs) such as levetiracetam (LEV) given the impression of comparable efficacy and superior tolerability. We set out to compare the efficacy of PHB and LEV in a large single-center cohort. METHODS: We retrospectively identified consecutive newborns with HIE who were monitored with continuous video-electroencephalogram (VEEG) for the duration of therapeutic hypothermia. After identification of seizures, infants were treated with PHB or LEV at the discretion of treating physicians. We assessed time to seizure freedom as a function of AED choice, with adjustment for HIE severity and initial seizure frequency using the Kaplan-Meier procedure and multivariate Cox proportional hazards regression. RESULTS: We identified 78 infants with HIE. Among 44 (56%) patients who had VEEG-confirmed seizures, 34 became seizure-free during monitoring, and the remaining 10 died. Initial treatment with LEV, in comparison with PHB, predicted a shorter interval to seizure freedom in a univariate analysis (Hazard ratio (HR) = 2.58, P = 0.007), even after adjustment for initial seizure frequency and an unbiased ad hoc measure of HIE severity (adjusted HR = 2.57, P = 0.010). This effect was recapitulated in an analysis in which patients with treatment crossover were excluded. As expected, severity of HIE was an independent predictor of longer duration to seizure freedom (HR = 0.16, P < 0.001) and remained a significant predictor after adjustment for initial seizure burden and treatment agent. CONCLUSION: Despite a relatively small sample size and retrospective design, this study suggests that LEV is a viable alternative to PHB in the treatment of neonatal seizures associated with HIE. A large-scale randomized controlled trial is needed to confirm these findings.

AB - Although the majority of late-onset Alzheimer's disease (AD) patients are labeled sporadic, multiple genetic risk variants have been identified, the most powerful and prevalent of which is the e4 variant of the Apolipoprotein E (APOE) gene. Here, we generated human induced pluripotent stem cell (hiPSC) lines from the peripheral blood mononuclear cells (PBMCs) of a clinically diagnosed AD patient [ASUi005-A] and a non-demented control (NDC) patient [ASUi006-A] homozygous for the APOE4 risk allele. These hiPSCs maintained their original genotype, expressed pluripotency markers, exhibited a normal karyotype, and retained the ability to differentiate into cells representative of the three germ layers.

AB - Primary Ciliary Dyskinesia (PCD) is a rare heterogeneous genetic disorder affecting motile cilia structure and function leading to lung disease. We generated induced pluripotent stem cells (iPSCs) from dermal fibroblasts of a female PCD patient carrying disease-causing variants in the CCDC40 gene. Reprogramming was performed with the human OSKM transcription factors using the Sendai-virus delivery system. The resulting transgene free iPSCs had normal karyotype, expressed pluripotency markers, could differentiate into the three germ layers in vivo and retained the disease-causing CCDC40 mutations. This iPSC line could be useful to model PCD disease and test gene therapy strategies. Resource Table.

AB - A direct-speech brain-computer interface (DS-BCI) acquires neural signals corresponding to imagined speech, then processes and decodes these signals to produce a linguistic output in the form of phonemes, words, or sentences. Recent research has shown the potential of neurolinguistics to enhance decoding approaches to imagined speech with the inclusion of semantics and phonology in experimental procedures. As neurolinguistics research findings are beginning to be incorporated within the scope of DS-BCI research, it is our view that a thorough understanding of imagined speech, and its relationship with overt speech, must be considered an integral feature of research in this field. With a focus on imagined speech, we provide a review of the most important neurolinguistics research informing the field of DS-BCI and suggest how this research may be utilized to improve current experimental protocols and decoding techniques. Our review of the literature supports a cross-disciplinary approach to DS-BCI research, in which neurolinguistics concepts and methods are utilized to aid development of a naturalistic mode of communication. PMID- 30296670 TI - Generation of an iPSC line of a patient with Angelman syndrome due to an imprinting defect. AB - Angelman syndrome (AS) is a neurodevelopmental disorder with leading symptoms of happy demeanor, intellectual disability, ataxia and seizures. AS can be caused by genetic and epigenetic aberrations, resulting in the absence of functional UBE3A protein in the brain. UBE3A is an imprinted gene, which is, in neurons of the brain, expressed exclusively from maternal chromosome 15. The generated iPSC line was derived from skin fibroblasts of a patient with AS, who, due to an imprinting defect, lacked DNA methylation at the chromosome 15 imprinting center, which controls maternal-specific expression of UBE3A.

AB - OBJECTIVES: To compare patellofemoral joint (PFJ) stress between level, incline, and decline running. DESIGN: Experimental study. SETTING: University laboratory. PARTICIPANTS: Twenty recreational runners. MAIN OUTCOME MEASURES: Kinematics and kinetics of the trunk and lower extremity were obtained under 3 treadmill conditions: level, 6 degrees incline, and 6 degrees decline. PFJ stress, PFJ reaction force, and PFJ contact area were determined using a biomechanical model. One-way ANOVAs with repeated measures and post-hoc analyses were used to compare outcome variables across the 3 conditions. RESULTS: Peak PFJ stress and PFJ stress-time integral (cumulative PFJ stress over the stance phase) during decline running were significantly higher than during level and incline running. There was no difference in peak PFJ stress and PFJ stress-time integral between level and incline running. The increased peak PFJ stress during decline running was related to increased PFJ reaction force, resulting from a decrease in trunk flexion angle. CONCLUSIONS: Running on a decline treadmill resulted in higher peak PFJ stress and stress-time integral. Peak PFJ stress and PFJ stress-time integral were similar during level and incline running. Results from this study may be used to prevent excessive PFJ stress during decline running, by targeting a postural strategy utilizing increased trunk flexion.

DESIGN: Intra-and inter-rater reliability and construct validity study. SETTINGS: Soccer club. PARTICIPANTS: Thirty-six asymptomatic boys, 10-16 years old. MAIN OUTCOME: The intra and inter-rater reliability of the Side Hop Test were analyzed by Intraclass Correlation Coefficient (ICC), Standard Error of Measurement (SEM), and Minimum Detectable Change (MDC). The construct validity of the Side Hop Test in reference to the Single Hop Test, the Standing Long Jump Test, the Shuttle Run, and isometric muscle strength was analyzed. RESULTS: The intra-rater ICC of the Side Hop Test ranged from 0.63 to 0.67, SEM ranged from 1.2 to 2.5 s, and MDC ranged from 2.8 to 5.7 s. The inter-rater ICC ranged from 0.83 to 0.91, SEM ranged from 0.6 to 0.8 s, and MDC ranged from 1.4 to 1.9 s. The Side Hop Test was significantly correlated (p < 0.05) with the Single Hop Test (r = -0.49) and the Standing Long Jump (r = -0.47). CONCLUSION: The results support the use of the Side Hop Test to evaluate children and adolescents. The measurements showed good intra-rater and very good inter-rater reliability.

AB - Considerable toxic volatiles (CO and HCN) generation and high fire hazard has definitely compromised the application of thermoplastic polyurethane (TPU). Here, a novel functionalization strategy for bulky h-BN is adopted to obtain the multifunctional CPBN, aiming at the flame retardancy reinforcement of TPU. The multifunctional CPBN is successfully prepared via the wrapping of phytic acid doped polypyrrole shell, following with the adsorption of copper ions. The obviously decreased peak heat release rate, peak smoke production rate and total smoke production values, obtained from cone test, confirms the reduced fire hazard of TPU composite with CPBN. The dramatic suppressions on CO and HCN releases can also be observed from TG-IR test. Tensile test demonstrates that adding CPBN favors the reinforcement in mechanical property of TPU. Thus, the concurrent improvements in flame retardancy and mechanical performance are achieved by incorporating CPBN. This work opens up new avenues for the functionalization of h-BN, and thus facilitates its promising applications in polymer-matrix composite.

AB - In this study, the vibrational frequencies of myristic acid (CH3(CH2)12COOH) were obtained using density functional theory calculations, and the results were compared with experimental Raman and infrared data. Additionally, Raman spectra of crystalline myristic acid were recorded in the 300-20 K range. Raman spectroscopy gives important insights into the effect of low temperatures on its monoclinic phase. X-ray diffraction was performed from 298 to 133 K to provide additional information about the cryogenic behavior of the crystals. These undergo a phase transformation, which was confirmed by differential scanning calorimetry through an enthalpy anomaly observed at low temperatures. Raman spectra and X-ray diffraction refinement of the cell parameters in combination with differential scanning calorimetry at low temperatures revealed slight modifications, confirming a conformational change in the myristic acid molecules involving rearrangement of dimers within the unit cell.

AB - OBJECTIVE: To define generic quality indicators for general hospital psychiatry from the perspectives of patients, professionals (physicians, nurses, and managers), and payers (health insurance companies). METHODS: Quality variables were identified by reviewing the relevant literature. A working. group consisting of patients', professionals' and payers' representatives was mandated by their respective umbrella organizations. The working group prioritized the quality variables that were identified. Core values were defined and subsequently linked to preliminary quality indicators. These were tested for feasibility in ten hospitals in a four-week period. Stakeholder consultation took place by means of two invitational conferences and two written commentary rounds. RESULTS: Forty one quality variables were identified from the literature. After prioritization, seven core values were defined and translated to 22 preliminary indicators. Overall, the feasibility study showed high relevance scores and good implementability of the preliminary quality indicators. A final set of twenty-two quality indicators (17 structure, 3 process and 2 outcome indicators) was then established using a consensus-based approach. CONCLUSION: Consensus on a quality framework for general hospital psychiatry was built by incorporating the perspectives of relevant stakeholders. Results of the feasibility study suggest broad support and good implementability of the final quality indicators. Structural indicators were broadly defined, and process and outcome indicators are generic to facilitate quality measurement across settings. The quality indicator set can now be used to facilitate quality and outcome assessment, stimulate standardization of services, and help demonstrate (cost-) effectiveness. PMID- 30296676 TI - Increase in economic efficiency of water use caused by crop structure adjustment in arid areas. AB - The Heihe River is located in the arid zone of northwestern China. In its middle reach region, irrigation agriculture is well developed. With rapid population growth and expansion of the cultivated land in this region, effective water resource use is vital for the sustainable development of the river basin and the increase of incomes from farming practices. In this study, based on farmer survey data, the input parameters of the CROPWAT model were modified, the water use amount was simulated after deducting the influences of climate, seeds, and irrigation systems, and the variation of economic efficiency of water use (EEWU) induced by crop structure adjustment from 2001 to 2012 was analyzed. The results show that simulations for evapotranspiration of maize based on the CROPWAT model are in accord with the observed data. From 2001 to 2012, due to changes in the regional crop structure, EEWU in the study area increased by about 40%. In the arid areas in northwest China, crop structure adjustment has a huge potential for improving EEWU and increasing incomes from farming practices. PMID- 30296677 TI - Evaluating and supporting conservation action in agricultural landscapes of the Usumacinta River Basin. AB - There is increasing recognition that ecosystems and their services need to be managed at landscape scale and greater. The development of landscape-scale conservation strategies need to incorporate information from multiple sources. In this study, we combine various research tools to link landscape patterns with production units and systems in the Usumacinta River Basin, and inform the discussion of key questions around decision-making related to conservation action and policy in Southern Mexico. A typology based on policy-relevant farmer characteristics (land tenure, farm size, source of income, farming system) differentiated between farmers (traditional vs. cattle ranching) with different motivations that determine how management affects landscape configuration. Five main types of traditional farming systems were identified that combine different forms of land use and vary in their degree of land intensification. Major fragmentation and decrease in connectivity coincided spatially with floodplains dominated by large-scale commercial farms that specialize in livestock production. Traditional practices within large units with low-sloped high quality land were also seen to be intensive; however the presence of trees was notable throughout these units. Policies that promote livestock farming are among the principle causes motivating deforestation. Land intensification by traditional farmers decreased as the landscape became increasingly rugged. Traditional farmers are the focus of initiatives developed by the Biological Corridor project which seeks to increase forest cover and landscape connectivity. These initiatives have shown high levels of rural participation (10,010 farmers benefited from 27,778 projects involving 95,374 ha of land) and acceptance (producers carried out more than one project and several types of projects during the first eight years of work). Strong action is still required to take on the segment of large-scale ranchers. Changes in the structure of land tenure over the past decade are highlighted that could have a profound impact on conservation policies and programs. PMID- 30296678 TI - Oil spill cleanup employing magnetite nanoparticles and yeast-based magnetic bionanocomposite. AB - Oil spill is a serious environmental concern, and alternatives to remove oils from water involving biosorbents associated to nanoparticles is an emerging subject. Magnetite nanoparticles (MNP) and yeast magnetic bionanocomposite (YB MNP) composed by yeast biomass from the ethanol industry were produced, characterized, and tested to remove new motor oil (NMO), mixed used motor oil (MUMO) and Petroleum 28 degrees API (P28API) from water following the ASTM F726 12 method, which was adapted by insertion of a lyophilization step to ensure the accuracy of the gravimetric approach. Temperature, contact time, the type and the amount of the magnetic material were the parameters evaluated employing a fractional factorial design. It was observed the removal of 89.0 +/- 2.6% or 3522 +/- 118 g/kg (NMO) employing MNP; 69.1 +/- 6.2% or 2841 +/- 280 g/kg (MUMO) with YB-MNP; and 55.3 +/- 8.2% or 2157 +/- 281 g/kg (P28API) using MNP. The temperature was the most significant parameter in accordance with the Pareto's graphics (95% confidence) for all oil samples considered in this study as well as the two magnetic materials. Contact time and the interaction between the materials and temperature were also relevant. The D-Optimals designs showed that the NMO and P28API responded in a similar way for all evaluated parameters, while the uptake of MUMO was favored at higher temperatures. These behaviors demonstrate the influence of oil characteristics and the intermolecular forces between the oil molecules on the mechanism dragging process performed by the attraction between magnetite nanoparticles and a 0.7 T magnet. It was clear that this kind of experiment is predominantly a physic phenomenon which cannot be described as adsorption process. PMID- 30296679 TI - Navigating protected areas networks for improving diffusion of conservation practices. AB - The Natura 2000 protected area network is the cornerstone of European Union's biodiversity conservation strategy. These protected areas range across multiple biogeographic regions, and they include a diversity of species assemblages along with a diversity of managing organizations, altogether making difficult to pool relevant sites to facilitate the flow of knowledge significant to their management. Here we introduce an approach to navigating protected area networks that has the potential to foster systematic identification of key sites for facilitating the exchange of knowledge and diffusion of information within the network. To demonstrate our approach, we abstractly represented Romanian Natura 2000 network as a co-occurrence network, with individual sites as nodes and shared species as edges, further combining into our analysis network topology, community detection, and network reduction methods. We identified most representative Natura 2000 sites that may increase the transfer of information within the national network of protected areas, detected clusters of sites and key sites for maintaining network cohesiveness, and highlighted the subsample of sites that retain the characteristics of the entire network. Our analysis provides implications for protected area prioritization by proposing a network perspective approach to collaboration rooted in ecological principles. PMID- 30296680 TI - Europe was a hub for the global spread of potato virus S in the 19th century. AB - Potato virus S (PVS) is a major plant pathogen that causes considerable losses in global potato production. Knowledge of the evolutionary history and spatio temporal dynamics of PVS is vital for developing sustainable management schemes. In this study, we investigated the phylodynamics of the virus by analysing 103 nucleotide sequences of the coat protein gene, sampled between 1985 and 2014. Our Bayesian phylogenetic analyses showed that PVS has been evolving at a rate of 3.32 * 10-4 substitutions/site/year (95% credibility interval 1.33 * 10-4-5.58 * 10-4). We dated the crown group to the year 1325 CE (95% credibility interval 762 1743 CE). Our phylogeographic analyses pointed to viral origins in South America and identified multiple migration pathways between Europe and other regions, suggesting that Europe has been a major hub for PVS transmission. The results of our study have potential implications for developing effective strategies for the control of this pathogen. PMID- 30296681 TI - Epithelial boost enhances antigen expression by vaccinia virus for the generation of potent CD8+ T cell-mediated antitumor immunity following DNA priming vaccination. AB - While both pNGVL4a-Sig/E7(detox)/HSP70 DNA vaccine and TA-HPV recombinant vaccinia viral vector-based vaccines have elicited HPV-specific CD8+ T cell responses in HPV16/E7-expressing tumor models, and been used as prime-boost regimen to enhance HPV-specific immune responses in humans (NCT00788164), the optimal route of administration for TA-HPV remains unclear. In a preclinical model, we examined the immunogenicity of priming with intramuscular pNGVL4a Sig/E7(detox)/HSP70 followed by TA-HPV boost through different administration routes. We observed that priming twice with a pNGVL4a-Sig/E7(detox)/HSP70 followed by a single TA-HPV immunization boost through skin scarification generated the strongest antigen-specific CD8+ T cell response in C57BL/6 mice. These data translate to tumor control and prolonged survival of treated mice. Our results provide rationale for future clinical testing of intramuscular pNGVL4a Sig/E7(detox)/HSP70 DNA vaccine prime, TA-HPV vaccine skin scarification boost immunization regimen for the control of HPV-associated diseases. PMID- 30296682 TI - Isolation and characterization of H5Nx highly pathogenic avian influenza viruses of clade 2.3.4.4 in Russia. AB - In 2016-2017, several subtypes of the highly pathogenic avian influenza (HPAI) virus were isolated on the territory of Russia. In the autumn of 2016, during the avian influenza virus surveillance in the territory of the Kamchatka region of Russia the HPAI A(H5N5) influenza virus was isolated. Then, during 2016-2017, multiple outbreaks among wild birds and poultry caused by HPAI A(H5N8) avian influenza virus were recorded in European part of Russia. At the end of 2017, an outbreak among poultry caused by HPAI A(H5N2) influenza virus was recorded in the European part of Russia. Phylogenetic analysis of HA of the A(H5N5), A(H5N8), A(H5N2) showed the strains belong to the clade 2.3.4.4 b. All isolated strains were antigenically closely related to candidate vaccine viruses of clade 2.3.4.4 and showed high virulence in mice. Genetic analysis revealed presence of genetic markers potentially related to high virulence in mice in all studied viruses. PMID- 30296683 TI - Hemozoin inhibiting 2-phenylbenzimidazoles active against malaria parasites. AB - The 2-phenylbenzimidazole scaffold has recently been discovered to inhibit beta hematin (synthetic hemozoin) formation by high throughput screening. Here, a library of 325,728 N-4-(1H-benzo[d]imidazol-2-yl)aryl)benzamides was enumerated, and Bayesian statistics used to predict beta-hematin and Plasmodium falciparum growth inhibition. Filtering predicted inactives and compounds with negligible aqueous solubility reduced the library to 35,124. Further narrowing to compounds with terminal aryl ring substituents only, reduced the library to 18, 83% of which were found to inhibit beta-hematin formation <100 MUM and 50% parasite growth <2 MUM. Four compounds showed nanomolar parasite growth inhibition activities, no cross-resistance in a chloroquine resistant strain and low cytotoxicity. QSAR analysis showed a strong association of parasite growth inhibition with inhibition of beta-hematin formation and the most active compound inhibited hemozoin formation in P. falciparum, with consequent increasing exchangeable heme. Pioneering use of molecular docking for this system demonstrated predictive ability and could rationalize observed structure activity trends. PMID- 30296684 TI - Design, synthesis and biological evaluation of 1,4-Diazobicylco[3.2.2]nonane derivatives as alpha7-Nicotinic acetylcholine receptor PET/CT imaging agents and agonists for Alzheimer's disease. AB - alpha7-Nicotinic acetylcholine receptor (alpha7-nAChR) agonists are promising therapeutic drug candidates for treating the cognitive impairment associated with Alzheimer's disease (AD). Thus, a novel class of derivatives of 1,4 diazobicylco[3.2.2]nonane has been synthesized and evaluated as alpha7-nAChR ligands. Five of them displayed high binding affinity (Ki = 0.001-25 nM). In particular, the Ki of 14 was 0.0069 nM, which is superior to that of the most potent ligand that was previously reported by an order of magnitude. Four of them had high selectivity for alpha7-nAChRs over alpha4beta2-nAChRs and no significant hERG (human ether-a-go-go-related gene) inhibition. Their agonist activity was also discussed preliminarily. One of the compounds, 15 (Ki = 2.98 +/- 1.41 nM), was further radiolabeled with 18F to afford [18F]15 for PET imaging, which exhibited high initial brain uptake (11.60 +/- 0.14%ID/g at 15 min post injection), brain/blood value (9.57 at 30 min post injection), specific labeling of alpha7-nAChRs and fast clearance from the brain. Blocking studies demonstrated that [18F]15 was alpha7-nAChR selective. In addition, micro-PET/CT imaging in normal rats further indicated that [18F]15 had obvious accumulation in the brain. Therefore, [18F]15 was proved to be a potential PET radiotracer for alpha7-nAChR imaging. PMID- 30296685 TI - Design, synthesis, and biological evaluation of novel pan agonists of FFA1, PPARgamma and PPARdelta. AB - The free fatty acid receptor 1 (FFA1) and peroxisome proliferator-activated receptors (PPARs) have attracted interest as potent targets for the treatment of metabolic syndrome such as type 2 diabetes. Based on the hypothesis that the dual agonists of PPARs and FFA1 would act as insulin sensitizers and secretagogues by simultaneous activation of PPARs and FFA1, we developed the design strategy to obtain dual PPARs/FFA1 agonist by hybrid FFA1 agonist 1 with PPARdelta agonist 2 in consideration of their structural similarity. As expected, systematic exploration of structure-activity relationship and molecular modeling, results in the discovery of lead compound 15, a pan agonist with relative balanced activities between FFA1, PPARgamma and PPARdelta. The dose-response relationship studies suggested that the pan agonist 15 suppressed the excursion of blood glucose levels in a dose-dependent manner. During a 5-days treatment in ob/ob mice, the pan agonist 15 (100 mg/kg) revealed sustained hypoglycemic effect, even proximity to the most advanced FFA1 agonist (TAK-875, 40 mg/kg), which might be attributed to its pan PPARs/FFA1 activities to simultaneous regulate the mechanism of insulin secretion and resistance. These positive results suggest that the dual PPARs/FFA1 agonists such as lead compound 15 might be novel therapeutic strategy to modulate the complex pathological mechanisms of type 2 diabetes. PMID- 30296686 TI - Design, synthesis and anti-mycobacterial activity evaluation of benzofuran-isatin hybrids. AB - Herein we report the design and synthesis of a series of novel benzofuran-isatin hybrids, and in vitro evaluation of their anti-mycobacterial activity against both drug-susceptible and multi-drug resistant (MDR) Mycobacterium tuberculosis (MTB) strains. In parallel, cytotoxicity of these hybrids was also tested in VERO cells. Preliminary results indicated that all hybrids with acceptable cytotoxicity in VERO cells (CC50: 128->1024 MUg/mL) exhibited considerable anti mycobacterial activities against MTB H37Rv and MDR-TB with MIC ranging from 0.25 to 8 MUg/mL. It is worth noting that hybrid 8f with no cytotoxicity towards VERO cells (CC50: >1024 MUg/mL) was found to be the most active compound (MIC: 0.25 and 0.5 MUg/mL) against MTB H37Rv and MDR-TB strains. Comparing to the first-line anti-tuberculosis agents rifampicin and isoniazid, hybrid 8f has shown over two magnitude more active against MDR-TB. The hybrid 8f was further evaluated for its metabolic stability and in vivo pharmacokinetic profiles, with the results showing that hybrid 8f exhibited lower metabolic stability compared to inhibitor TAM16. Further modification based on hybrid 8f is needed to improve the metabolic stability and pharmacokinetic profiles. PMID- 30296687 TI - Hybrid compounds from chalcone and 1,2-benzothiazine pharmacophores as selective inhibitors of alkaline phosphatase isozymes. AB - Chalcones and 1,2-benzothiazines are two important classes of bioactive compounds, each scaffold endowed with diverse pharmacological activities. Combining both of these pharmacophores in a single molecule was aimed to yield multi-modal agents. Herein, we report a series of hybrid compounds 3a-3o derived from chalcones and 1,2-benzothiazine cores. They were synthesized from commercially available sodium saccharin, and the resulting 1,2-benzothiazine derived ketone was then condensed with aromatic aldehydes in an aldol condensation to obtain the respective chalcones. The compounds were characterized using different analytical techniques including FT-IR, NMR spectroscopy, mass spectrometry and X-ray crystallography. Some synthesized chalcones revealed potent and/or selective inhibitory properties towards alkaline phosphatase isozymes transiently expressed in COS-7 cells. A detailed structure-activity and selectivity study was carried out with regard to the effect of different substituents at ortho-, meta- and para-positions of the phenyl residue. Compound 3c was the most effective human intestinal alkaline phosphatase (h-IAP) inhibitor (IC50 value of 1.04 MUM), while it was not active against human tissue non specific alkaline phosphatase (h-TNAP) isozyme. In contrast, 3i was a selective inhibitor of h-TNAP with IC50 values of 0.25 +/- 0.01 MUM. The possible binding interactions of the most effective inhibitors of h-TNAP and h-IAP were obtained from molecular docking studies. PMID- 30296688 TI - Novel potential pyrazolopyrimidine based translocator protein ligands for the evaluation of neuroinflammation with PET. AB - Translocator protein (TSPO) is an interesting biological target because TSPO overexpression is associated with microglial activation caused by neuronal damage or neuroinflammation, and these activated microglia are involved in several central nervous system diseases. Herein, novel fluorinated ligands (14a-c and 16a c) based on a 2-phenylpyrazolo[1,5-a]pyrimidin-3-yl acetamide scaffold were synthesized, and in vitro characterization of each of the novel ligands was performed to elucidate structure activity relationships. All of the newly synthesized ligands displayed nano-molar affinity for TSPO. Particularly, an in vitro affinity study suggests that 2-(5,7-diethyl-2-(4-(3-fluoro-2 methylpropoxy)phenyl)pyrazolo[1,5-a]pyrimidin-3-yl)-N,N-diethylacetamide (14a), which exhibited high nano-molar affinity for TSPO and proper lipophilicity, was suitable for in vivo brain studies. Thus, radiosynthesis from tosylate precursor 13a using fluorine-18 was performed, and [18F]14a was obtained in a 31% radiochemical yield (decay-corrected). Dynamic positron emission tomography (PET) imaging studies were performed in a lipopolysaccharide (LPS)-induced neuroinflammation rat model using [18F]14a to identify the location of inflammation in the brain with a high target-to-background signal ratio. In addition, we validated that the locations of inflammatory lesions found by PET imaging were consistent with the locations observed by histological examination of dissected brains using antibodies. These results suggest that [18F]14a is a novel promising PET imaging agent for diagnosing neuroinflammation, and it may also prove to be applicable for diagnosing other diseases, including cancers associated with altered TSPO expression, using PET techniques. PMID- 30296689 TI - 137Cs and K annual fluxes in a cropland and forest ecosystems twenty-four years after the Chernobyl accident. AB - Biological cycles of the Chernobyl originated cesium-137 (137Cs, radiocesium) and the natural potassium (K) in oak, birch, and pine forest, and wheat cropland in Russian Federation, approximately 500 km northeast of the Chernobyl Nuclear Power Plant, were subject to a multiyear monitoring. By 2010, the annual return of 137Cs from forest vegetation to the soil in dead tree components still exceeds its annual accumulation in the tree phytomass by a factor of 4-6, apparently due to residual surface contamination in the external bark and the ongoing process of tree stand decontamination following the initial fallout. In the cropland, both ascending and descending fluxes of 137Cs are close to the steady state. The annual accumulation of 137Cs in the tree biomass was the highest in the oak forest and the lowest in the pine forest. The annual K accumulation was the highest in the cropland and the lowest in the pine forest. PMID- 30296690 TI - Metal regulation of metabolism. AB - A broad range of biochemicals, from proteins to nucleic acids, function properly only when associated with a metal, usually a divalent cation. Not any divalent metal will do: these metals differ in their ionic radius, dissociation in water, ionization potential, and number of unpaired electrons in their outer shells, and so substituting one metal for another often changes substrate positioning, redox reactivities, and physiological performance, and thus may serve as a regulatory mechanism. For instance, exchanging manganese for magnesium in several chloroplast enzymes maintains plant carbon-nitrogen balance under rising atmospheric CO2 concentrations. Here, we review this and a few other cases where association of proteins or nucleic acids with different metals control metabolism. PMID- 30296691 TI - An analysis of the nutrition status of neighboring Indigenous and non-Indigenous populations in Kanungu District, southwestern Uganda: Close proximity, distant health realities. AB - OBJECTIVES: Malnutrition is a persistent health concern throughout the world. Globally, Indigenous peoples experience poorer health outcomes compared to their non-Indigenous neighbours. Despite this, malnutrition among Indigenous populations is poorly understood. This analysis estimated the prevalence, and modeled possible determinants of, moderate acute malnutrition (MAM) and severe acute malnutrition (SAM) for Indigenous Batwa and non-Indigenous Bakiga of Kanungu District in Southwestern Uganda. We then characterize possible mechanisms driving differences in malnutrition. METHODS: Retrospective cross-sectional surveys were administered to 10 Batwa communities and 10 matched Bakiga Local Councils during April of 2014 (n = 1167). Individuals were classified as MAM and SAM based on middle upper-arm circumference (MUAC) for their age-sex strata. Mixed-effects regression models quantified the variation in malnutrition occurrence, considering individual, household, and community-ethnicity level effects. Models controlled for age, sex, number of dependents, education, and relative wealth. RESULTS: Malnutrition is high among Batwa children and adults, with nearly half of Batwa adults (45.34%, 95% CI 34.82 to 55.86 for males; 45.86%, 95% CI 37.39 to 54.33 for females) and nearly a quarter of Batwa children (20.31%, 95% CI 13.07 to 26.93 for males; 25.81%, 95% CI 17.56 to 32.84 for females) meeting MAM criteria. SAM prevalence is lower than MAM prevalence, with SAM highest among adult Batwa males (11.60%, 95% CI 4.83 to 18.37) and adult Batwa females (3.00%, 95% CI 0.10 to 5.90). SAM prevalence among children was higher for Batwa males (7.03%, 95% CI 1.36 to 12.70) compared to Bakiga males (0.57%, 95% CI 0 to 1.69). Models that incorporated community ethnicity explained the greatest variance (>60%) in MUAC values. CONCLUSION: This research demonstrates a malnutrition inequality between the Indigenous Batwa and non Indigenous Bakiga of Kanungu District, Uganda, with model results suggesting further investigation into the role of ethnicity as an upstream social determinant of health. PMID- 30296693 TI - The effect of job loss on pharmaceutical prescriptions. AB - We estimate the effect of job loss on the probability that long-tenured workers are prescribed anti-hypertensive and psychotropic drugs. We exploit two administrative data sources from the Veneto region in Italy and estimate an event study model. Our results indicate that the probability of drug prescription increases among under-40 males but not among older males or female workers. We suggest that the effect on younger male workers is the combined result of their typical role as breadwinners, limited wealth buffers in case of layoff, and unfavourable employment legislative protection. PMID- 30296692 TI - Association between family members and risk of postpartum depression in Japan: Does "who they live with" matter? -The Japan environment and Children's study. AB - There are many psychosocial and biomedical risk factors for postpartum depression (PPD). However, associations between co-resident family members and PPD risk have not been examined. This study investigated whether co-resident family members were associated with risk for PPD during 1 month postpartum among Japanese women, and if these associations were modified by household income and their perceived partner's involvement in childcare. The sample comprised 86,490 women. Data were drawn from the Japan Environment and Children's Study, a large-scale national cohort study started in 2011. Our major predictor was co-resident family members when they registered around the first trimester of the women's pregnancy: partner, parent(s), parent(s)-in-law, or child(ren). The outcome was PPD at 1 month after delivery, assessed by the Edinburgh Postnatal Depression Scale. Adjusted odds ratios (OR) for family members and PPD incidence were calculated using multivariable logistic regression analysis. Subgroup analyses were conducted by household income and perceived partner's involvement in childcare. Adjusted ORs (95% confidence interval) for PPD for those not living with their partner, parent(s), parent(s)-in-law, or child(ren) compared with those who lived with these family members were 1.21 (1.07-1.37), 1.13 (1.03-1.24), 0.91 (0.84 0.98), and 1.42 (1.31-1.53), respectively. The level of perceived partner's involvement in childcare changed the identified association between family member and PPD. We found that "who a pregnant woman lives with" affects the risk of PPD in the first month postpartum, and high levels of perceived partner's involvement in childcare reduced harmful effects/increased protective effect of family members on PPD incidence. These findings suggested that interventions to increase perceived partner's support for childcare may be effective in preventing PPD, regardless of living situation. PMID- 30296694 TI - Long-term effects of disaster on depressive symptoms: Type of exposure matters. AB - RATIONALE: Natural disasters have the potential to change the lives of older people, yet most studies rely on small convenience samples, few include assessments of people prior to the disaster, and only a handful examine the effects of different types of exposure. OBJECTIVE: Our analyses add new knowledge to the literature by examining the ways in which four types of exposure (i.e., geographic, peri-traumatic stress, personal and property loss, and post-storm hardship) affect depressive symptoms experienced by older people over a five-year period. METHOD: We analyzed four waves of data from the ORANJ BOWL panel using multilevel mixed effects models. RESULTS: We found that although each type of exposure had an independent effect on depressive symptoms, the effects of peri traumatic stress were dominant. CONCLUSIONS: As nearly 20% of people in the United States will experience a natural disaster during the course of their lives, it is critical to understand how disaster exposure can influence mental health because each type of exposure demands a different response. Finding that an individual's emotional response during the disaster plays an important role in the development of depressive symptoms suggests that reduction of exposure to traumatic stress during a storm (i.e., evacuation from a storm area) is important for older people. Likewise, immediate interventions following a disaster that target people experiencing high levels of peri-traumatic distress may be particularly effective and that failing to attend to these people may miss a critical opportunity and result in years of suffering. PMID- 30296695 TI - Prenatal exposure to air pollution and intergenerational economic mobility: Evidence from U.S. county birth cohorts. AB - New estimates reveal intergenerational economic mobility varies substantially across U.S. counties. The potential role of local environmental health exposures in structuring mobility outcomes has been thus far unexamined, despite mounting evidence that early life exposure to environmental pollutants has lasting impacts for individual human capital development and labor market performance. This study aims to fill this gap by estimating the impact of exposure to air pollution in the birth year on the average intergenerational mobility outcomes of children from low-income families as measured in adulthood. We do so by linking measures of intergenerational economic mobility for U.S. county-cohorts born between 1980 and 1986 to the county average concentration of total suspended particulates (TSP) in the birth year. We then estimate multivariate linear regression models that adjust for birth-cohort fixed effects, county-fixed effects and time-varying county-level covariates to address potential confounding. We find higher levels of TSP in birth year is associated with less upward economic mobility for children from low-income families: a one standard deviation increase in TSP levels is associated with a 0.14 point reduction in average income percentile ranking as measured in adulthood. Notably, we find no association for children from high income families. Our findings indicate early life exposure to air pollution may reduce the prospects children from low-income families will achieve upward economic mobility and suggest variation in environmental quality may help explain observed variation in mobility outcomes. PMID- 30296697 TI - Dose-related impacts of imidacloprid oral intoxication on brain and liver of rock pigeon (Columba livia domestica), residues analysis in different organs. AB - Available data regarding Imidacloprid (IMI) insecticide hazards to birds are still being scare. Our study aimed to investigate toxic impacts of IMI oral gavage by different dose levels on the brain and liver of Rock pigeon (Columba livia domestica). Forty mature male birds were divided equally into four groups. A control group (C) was orally dosed Mazola corn oil and other three groups; the low dose (LD), the medium dose (MD), and the high dose (HD) groups were orally dosed IMI in Mazola corn oil by three dose levels corresponding to 1/15th, 1/10th, 1/5th IMI oral LD50 respectively. IMI exposure induced a significant decrease in serum levels of glutathione (GSH), superoxide dismutase (SOD) enzyme activity. On the other hand; malondialdehyde (MDA) levels were elevated. The levels of serum total protein, albumin, globulin, and A/G ratio showed a non significant changes in all IMI dosed groups except levels of total protein in the HD IMI dosed group showed a significant decrease compared to the C group. Serum levels of alanine aminotransferase (ALT), lactate dehydrogenase (LDH), uric acid, plasma tumor necrosis factor alpha (TNFalpha) and plasma acetylcholinesterase (AChEs) enzyme activities showed a significant dose related increase in all IMI exposed groups compared to the C group; except the levels of ALT, LDH, and uric acid showed a non significant decrease in the LD IMI dosed group only. Residues of IMI were detected in the pectoral muscles, liver, brain, and kidney of all dosed rock pigeon. Moreover; pectoral muscles were the highest tissue for IMI residues detection. This is the first study reports accumulation of IMI in tissues other than crop, liver, and kidney of rock pigeon including brain and muscles. Moreover, the examined brain and liver tissues of all IMI dosed groups showed dosed related alterations in their structural and ultra-structural morphology. It is concluded that IMI oral administration to pigeon induced oxidative stress and detrimental effects in brain and liver of exposed pigeons. Additionally; IMI bio-accumulated in different organs being muscles is the highest tissues for IMI residues, thus monitoring of IMI residues in food is very essential.

AB - Produced as linear biopolymers from four major types of building blocks, DNA and RNA are further furnished with a range of covalent modifications. Despite the impressive specificity of natural enzymes, the transferred groups are often poor reporters and not amenable to further derivatization. Therefore, strategies based on repurposing some of these enzymatic reactions to accept derivatized versions of the transferrable groups have been exploited. By far the most widely used are S-adenosylmethionine-dependent methyltransferases, which along with several other nucleic acids modifying enzymes offer a broad selection of tagging chemistries and molecular features on DNA and RNA that can be targeted in vitro and in vivo. Engineered enzymatic reactions have been implemented in validated DNA sequencing based protocols for epigenome analysis. The utility of chemo-enzymatic labeling is further enhanced with recent advances in physical detection of individual reporter groups on DNA using super resolution microscopy and nanopore sensing enabling single-molecule multiplex analysis of genetic and epigenetic marks in minute samples. Altogether, a number of new powerful techniques are currently in use or on the verge of real benchtop applications as research tools or next generation diagnostics. PMID- 30296698 TI - Toxicity and cytotoxicity of the insecticide imidacloprid in the midgut of the predatory bug, Podisus nigrispinus. AB - The selectivity of insecticides on natural enemies in pest control are an important strategy for Integrated Pest Management. However, insecticides can have side effects on non-target organisms such as natural enemies. This study evaluated the histological and cytological changes mediated by the sublethal concentration of the imidacloprid insecticide on the midgut of non-target predator Podisus nigrispinus (Heteroptera: Pentatomidae), used in the biological control of pests. Imidacloprid was toxic for P. nigrispinus with LC50 = 3.75 mg L 1 and survival of 51.8%. This sublethal concentration of imidacloprid causes histological alterations in the midgut epithelium and cytotoxic features were irregular border epithelium, cytoplasmic vacuolation, and apocrine secretions in the first 6 h after exposure with the insecticide. Apoptosis in the digestive cells occurs after 12 h of exposure in the midgut. These results suggest that imidacloprid may affect the digestive physiology of P. nigrispinus and compromise the effective predation of this insect a biological control agent. The associated use of this insecticide with the predator in pest control should be carefully evaluated. PMID- 30296699 TI - Restoration of SERCA ATPase prevents oxidative stress-related muscle atrophy and weakness. AB - Molecular targets to reduce muscle weakness and atrophy due to oxidative stress have been elusive. Here we show that activation of Sarcoplasmic Reticulum (SR) Ca2+ ATPase (SERCA) with CDN1163, a novel small molecule allosteric SERCA activator, ameliorates the muscle impairment in the CuZnSOD deficient (Sod1-/-) mouse model of oxidative stress. Sod1-/- mice are characterized by reduced SERCA activity, muscle weakness and atrophy, increased oxidative stress and mitochondrial dysfunction. Seven weeks of CDN1163 treatment completely restored SERCA activity and reversed the 23% reduction in gastrocnemius mass and 22% reduction in specific force in untreated Sod1-/- versus wild type mice. These changes were accompanied by restoration of autophagy protein markers to the levels found in wild-type mice. CDN1163 also reversed the increase in mitochondrial ROS generation and oxidative damage in muscle tissue from Sod1-/- mice. Taken together our findings suggest that the pharmacological restoration of SERCA is a promising therapeutic approach to counter oxidative stress-associated muscle impairment. PMID- 30296700 TI - AVE 0991 attenuates oxidative stress and neuronal apoptosis via Mas/PKA/CREB/UCP 2 pathway after subarachnoid hemorrhage in rats. AB - Oxidative stress and neuronal apoptosis have been demonstrated to be key features in early brain injury (EBI) after subarachnoid hemorrhage (SAH). Previous studies have indicated that Mas receptor activation initiates an anti-oxidative and anti apoptotic role in the brain. However, whether Mas activation can attenuate oxidative stress and neuronal apoptosis after SAH remains unknown. To investigate the beneficial effect of Mas on oxidative stress injury and neuronal apoptosis induced by SAH, a total of 196 rats were subjected to an endovascular perforation model of SAH. AVE 0991 (AVE), a selective agonist of Mas, was administered intranasally 1 h after SAH induction. A779, a selective inhibitor of Mas, and small interfering ribonucleic acid (siRNA) for UCP-2 were administered by intracerebroventricular (i.c.v) injection at 1 h and 48 h before SAH induction respectively. Neurological tests, immunofluorescence, TUNEL, Fluoro-Jade C, DHE staining, and Western blot experiments were performed. We found that Mas activation with AVE significantly improved neurobehavioral scores and reduced oxidative stress and neuronal apoptosis in SAH+AVE group compared with SAH+vehicle group. Moreover, AVE treatment significantly promoted phosphorylation of CREB and the expression UCP-2, as well as upregulated expression of Bcl-2 and downregulation of Romo-1 and Bax. The protective effects of AVE were reversed by i.c.v injection of A779 and UCP-2 siRNA in SAH+AVE+A779 and SAH+AVE+UCP-2 siRNA groups, respectively. In conclusion, our data provides evidence that Mas activation with AVE reduces oxidative stress injury and neuronal apoptosis through Mas/PKA/p-CREB/UCP-2 pathway after SAH. Furthermore, our study indicates that Mas may be a novel therapeutic treatment target in early brain injury of SAH. PMID- 30296703 TI - Suitability of developed composite materials for meniscal replacement: Mechanical, friction and wear evaluation. AB - The meniscus is a complex and frequently damaged tissue which requires a substitute capable of reproducing similar biomechanical functions. This study aims to develop a synthetic meniscal substitute that can mimic the function of the native meniscus. Medical grade silicones reinforced with nylon were fabricated using compression moulding and evaluated for mechanical and tribological properties. The optimal properties were obtained with tensile modulus increased considerably from 10.7 +/- 2.9 MPa to 114.6 +/- 20.9 MPa while compressive modulus was found to reduce from 2.5 +/- 0.6 MPa to 0.7 +/- 0.3 MPa. Using a tribometer, the coefficient of friction of 0.08 +/- 0.02 was measured at the end of the 100,000 cycles. The developed composite could be an auspicious substitute for the native meniscus and the knowledge gained from this study is useful as it enhances the understanding of a potentially suitable material for meniscal implants. PMID- 30296701 TI - Fenofibrate improves vascular endothelial function and contractility in diabetic mice. AB - Fenofibrate, a peroxisome proliferator-activated receptors alpha (PPARalpha) agonist, reduces vascular complications of diabetic patients but its protective mechanisms are not fully understood. Here we tested the hypothesis that fenofibrate improves vascular endothelial dysfunction by balancing endothelium dependent relaxation and contractility of the aorta in diabetes mellitus (DM). In streptozotocin-induced diabetic mice, eight weeks of fenofibrate treatment (100 mg/Kg/d) improved endothelium dependent relaxation in the macro- and microvessels, increased nitric oxide (NO) levels, reduced renal damage markers and effects of the vasoconstrictor prostaglandin. Levels of superoxide dismutase and catalase were both reduced and hydrogen peroxide was increased in vehicle treated DM, but these changes were reversed by fenofibrate treatment. Vasodilation of the aorta after fenofibrate treatment was reversed by PPARalpha or AMPKalpha inhibitors. Western blots showed that fenofibrate treatment elevated PPARalpha expression, induced liver kinase B1 (LKB1) translocation from the nucleus to the cytoplasm and activated AMP-activated protein kinase-alpha (AMPKalpha), thus activating endothelial NO synthase (eNOS). Also, fenofibrate treatment decreased NF-kappaB p65 and cyclooxygenase 2 proteins in aortas. Finally, incubation with indomethacin in vitro improved aortic contractility in diabetic mice. Overall, our results show that fenofibrate treatment in diabetic mice normalizes endothelial function by balancing vascular reactivity via increasing NO production and suppressing the vasoconstrictor prostaglandin, suggesting mechanism of action of fenofibrate in mediating diabetic vascular complications. PMID- 30296702 TI - Persistent increase in mitochondrial superoxide mediates cisplatin-induced chronic kidney disease. AB - Severe and recurrent cisplatin-induced acute kidney injury (AKI) as part of standard cancer therapy is a known risk factor for development of chronic kidney disease (CKD). The specific role of superoxide (O2*-)-mediated disruption of mitochondrial oxidative metabolism in CKD after cisplatin treatment is unexplored. Cisplatin is typically administered in weekly or tri-weekly cycles as part of standard cancer therapy. To investigate the role of O2*- in predisposing patients to future renal injury and in CKD, mice were treated with cisplatin and a mitochondrial-specific, superoxide dismutase (SOD) mimetic, GC4419. Renal function, biomarkers of oxidative stress, mitochondrial oxidative metabolism, and kidney injury markers, as well as renal histology, were assessed to evaluate the cellular changes that occur one week and one month (CKD phase) after the cisplatin insult. Cisplatin treatment resulted in persistent upregulation of kidney injury markers, increased steady-state levels of O2*-, increased O2*- mediated renal tubules damage, and upregulation of mitochondrial electron transport chain (ETC) complex I activity both one week and one month following cisplatin treatment. Treatment with a novel, clinically relevant, small-molecule superoxide dismutase (SOD) mimetic, GC4419, restored mitochondrial ETC complex I activity to control levels without affecting complexes II-IV activity, as well as ameliorated cisplatin-induced kidney injury. These data support the hypothesis that increased mitochondrial O2*- following cisplatin administration, as a result of disruptions of mitochondrial metabolism, may be an important contributor to both AKI and CKD progression. PMID- 30296704 TI - Mechanical properties and cytotoxicity of hierarchical carbon fiber-reinforced poly (ether-ether-ketone) composites used as implant materials. AB - Weak mechanical properties affect the application of PEEK as an implant. Carbon fiber (CFR) reinforcement provides an excellent solution to improve the mechanical strength of PEEK and to provide perfect matching of elastic modulus between CFR-PEEK composites and human bone. To investigate the effect of carbon fiber content on the mechanical, thermal properties and cytotoxicity of CFR reinforced PEEK composites, a series of CFR-PEEK composites with different carbon fiber content (25 wt%, 30 wt%, 35 wt%, 40 wt%) was prepared in this work. Thermal decomposition behavior and melting temperature were studied by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), respectively. Subsequently, mechanical properties including bending strength, compressive strength, impact strength and hardness were tested respectively. Afterwards, the fracture morphology of the bending test samples was observed by scanning electron microscopy (SEM). In addition, murine fibroblast L929 cells were adopted for cytotoxicity test by CCK-8 assay in vitro, and the morphology of cells was observed by inverted fluorescence microscope simultaneously, cell compatibility of CFR-PEEK composites was tested. PMID- 30296705 TI - Current evolutionary adaptiveness of anxiety: Extreme phenotypes of anxiety predict increased fertility across multiple generations. AB - OBJECTIVE: Although recent research has begun to examine the impact of elevated anxiety on evolutionary fitness, no prior research has examined anxiety across a continuum. Such research is important as the effect of traits across a continuum on fertility hold important implications for the levels and distribution of the traits in later generations. METHOD: In a three-generational sample (N = 2657) the linear and quadratic relationship between anxiety and the number of children, grandchildren, and great-grandchildren 15 years later was examined. RESULTS: The findings suggested that anxiety had a positive quadratic relationship with the number of children, grandchildren, and great-grandchildren 15 years later. These relationships were not significantly moderated by sex. Moreover, most of the variance between anxiety and the number of great-grandchildren was explained by anxiety's influence on the number of children and grandchildren, as opposed to anxiety having an independent direct impact on the number of great-grandchildren. CONCLUSION: These findings suggest that extreme values from the mean anxiety are associated with increased evolutionary fitness within the modern environment. PMID- 30296706 TI - Sex differences during emotion processing are dependent on the menstrual cycle phase. AB - Sex differences in the neural processing of emotion are of special interest considering that mood and anxiety disorders predominant in females. However, these sex-related differences were typically studied without considering the hormonal status of female subjects, although emotion processing in the brain was shown to differ between phases of the menstrual cycle. In this functional MRI study, we demonstrated the influence of the menstrual cycle phase on sex differences in brain activity and functional connectivity during negative and positive emotions, using two different paradigms: emotion perception and emotion experience. Twenty naturally cycling healthy women without premenstrual symptoms were scanned twice: during the mid-follicular and late-luteal menstrual phases, and compared to a matched group of twenty healthy men. During negative emotion perception, men showed increased neural activity in the right hippocampal formation relative to women in the mid-follicular phase, and increased activity in the right cerebellum relative to women in the late-luteal phase. During experience of amusement, reduced putamen-ventrolateral prefrontal cortex and putamen-dorsomedial prefrontal cortex functional connectivity were observed for women in the late-luteal phase relative to men and associated with levels of sex hormones. These neural and hormonal findings were complemented by behavioral reports of reduced amusement and increased sadness in late-luteal women. Our results demonstrate menstrual phase-dependent sex differences in emotion perception and experience and may suggest a biological tendency for a deficient experience of pleasure and reward during the late-luteal phase. These findings may further shed light on the underlying pathophysiology of premenstrual dysphoric disorder. PMID- 30296707 TI - Tissue-specific localization of polyketide synthase and other associated genes in the lichen, Cladonia rangiferina, using laser microdissection. AB - The biosynthesis of two polyketides, atranorin and fumarprotocetraric acid, produced from a lichen-forming fungus, Cladonia rangiferina (L.) F. H. Wigg. was correlated with the expression of eight fungal genes (CrPKS1, CrPKS3, CrPKS16, Catalase (CAT), Sugar Transporter (MFsug), Dioxygenase (YQE1), C2H2 Transcription factor (C2H2), Transcription Factor PacC (PacC), which are thought to be involved in polyketide biosynthesis, and one algal gene, NAD-dependent deacetylase sirtuin 2 (AsNAD)), using laser microdissection (LMD). The differential gene expression levels within the thallus tissue layers demonstrate that the most active region for potential polyketide biosynthesis within the lichen is the outer apical region proximal to the photobiont but some expression also occurs in reproductive tissue. This is the first study using laser microdissection to explore gene expression of these nine genes and their location of expression; it provides a proof-of-concept for future experiments exploring tissue-specific gene expression within lichens; and it highlights the utility of LMD for use in lichen systems. PMID- 30296709 TI - Single bout of low-intensity exercise produces modestly favorable changes in glycemic and lipidemic profiles after ingestion of non-isoglucidic breakfasts. AB - OBJECTIVES: The aim of this study was to investigate the acute effects of low intensity exercise on the postprandial hormonal and metabolic milieu induced by breakfast consumption. METHODS: Exercise began 100min after the initiation of breakfast consumption and consisted of cycling at 40% of maximum oxygen uptake for 20min. Three different breakfasts were used to elicit the postprandial state: B1 = skimmed milk (125 mL) and 30g corn flakes; B2 = skimmed milk (220 mL), 200g apple, 30g cocoa cream-filled sponge cake; B3 = skimmed milk (125 mL), 50g bread, 150g apple, and 15g hazelnut and cocoa spread. Nineteen young healthy participants (8M/11 F; body mass index 22.7 +/- 0.5 kg/m2; age 31 +/- 0.7 y) consumed the three breakfasts, as well as an oral glucose load (50-g oral glucose tolerance test), under either resting or exercise conditions, in a randomized crossover fashion. Blood glucose, insulinemia, ghrelinemia, lipidemia, and satiety were measured throughout the studies. To evaluate the metabolic effects of exercise, the changes that glucose, insulin, ghrelin, free fatty acid exhibited in the interval 90 to 120min were analyzed with a two-way repeated measures analysis of variance (factor 1: type of oral test; factor 2: resting/exercise condition). RESULTS: No interaction between the two factors was found for any of the examined variables. Light exercise produced a modest, significant decrease in blood glucose levels (P = 0.004) and a modest, significant increase in free fatty acid levels (P = 0.002) with respect to the resting condition. CONCLUSIONS: These findings suggest that short, mild exercise has beneficial effects on postprandial metabolism and this may have direct bearing on the issue of counteracting the epidemic rising of sedentary lifestyle of the general population. PMID- 30296708 TI - Hydroxylated furanoditerpenoids from pupal cases produced by the bruchid beetle Sulcobruchus sauteri inside the seeds of Caesalpinia decapetala. AB - Seven undescribed hydroxylated cassane-type furanoditerpenoids were isolated from pupal cases formed from the secretion/excretion of the larvae of the wild bruchid seed beetle Sulcobruchus sauteri in infested Caesalpinia decapetala seeds, and their structures were elucidated by interpreting their spectra. The hydroxylated furanoditerpenoids found in the pupal cases were not present in the seeds of the host plant. Caesalacetal and caesaljapin obtained from the intact seeds exhibited larvicidal activity against the larvae of Aedes albopictus, while the hydroxylated furanoditerpenoids isolated from the pupal cases were inactive. The larvae of S. sauteri are proposed to detoxify larvicidal diterpenoids that occur in the seeds of the host plant by regiospecific hydroxylation.

AB - The objective of this study was to present heritability estimates and accuracy of genomic prediction using different methods for meat quality traits in Nelore cattle. Approximately 5000 animals with phenotypes and genotypes of 412,000 SNPs, were divided into two groups: (1) training population: animals born from 2008 to 2013 and (2) validation population: animals born in 2014. A single-trait animal model was used to estimate heritability and to adjust the phenotype. The methods of GBLUP, Improved Bayesian Lasso and Bayes Cpi were performed to estimate the SNP effects. Accuracy of genomic prediction was calculated using Pearson's correlations between direct genomic values and adjusted phenotypes, divided by the square root of heritability of each trait (0.03-0.19). The accuracies varied from 0.23 to 0.73, with the lowest accuracies estimated for traits associated with fat content and the greatest accuracies observed for traits of meat color and tenderness. There were small differences in genomic prediction accuracy between methods. PMID- 30296712 TI - Quantitative analysis of serum chemokines associated with treatment failure of direct-acting antivirals in chronic hepatitis C. AB - Although serum chemokine levels have been reported to influence the outcome of interferon-based treatment in patients with chronic hepatitis C, their effect on the hepatitis C virus (HCV) response to direct-acting antiviral agents (DAAs), which can achieve high rates of a sustained virological response (SVR), is largely unknown. To clarify this relationship, 9 chemokines (eotaxin, GRO-alpha, IL-8, IP-10, MCP-1, MIP-1alpha, MIP-1beta, RANTES, and SDF-1alpha) were quantified before, during, and after DAA treatment using serum samples obtained from 57 patients with chronic hepatitis C. All baseline median chemokine levels were significantly higher in patients with chronic hepatitis C than in healthy subjects (P < 0.05). In particular, lower MIP-1beta (<=71.5 pg/mL) and higher RANTES (>671.5 pg/mL) levels were significantly associated with patients who failed to clear HCV RNA (P = 0.0039 and 0.013, respectively). Prediction of a clinical response based on a combination of these chemokines demonstrated high sensitivity (82%), specificity (85%), negative predictive value (95%), and area under the curve (0.833). The non-SVR rate (56.3%; 9 of 16) was significantly higher in patients with low MIP-1beta and high RANTES compared with other combinations. Moreover, baseline MIP-1beta and RANTES were both additive and independent for predicting a non-SVR. Apart from an increase in eotaxin, all chemokines became decreased in patients with a SVR. In conclusion, a combination of serum MIP-1beta and RANTES levels may be predictive of a treatment response to DAAs in Japanese patients with chronic hepatitis C. PMID- 30296713 TI - Influence of proinflammatory cytokine gene polymorphisms on the risk of COPD and the levels of plasma protein. AB - INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is a complex and multifactorial disease involving systemic inflammation. Although certain genetic components have been implicated in the development and progression of this disease, few studies have examined the participation of polymorphisms in proinflammatory genes and the extent to which polymorphisms are related to plasma levels of cytokines involved in the inflammatory process. METHODS: Of the 1125 smokers participating in the study, 438 had COPD, and 687 did not. We determined the genotype of 5 SNPs distributed in the genes: IL6, CXL8, CSF2, CCL1 and IL1B. The plasma protein expression of these genes was also evaluated and categorized according to genotype and the severity of COPD (GOLD grade). RESULTS: An analysis using the codominant model showed an association between rs1818879 in IL6 and susceptibility to COPD (GA OR = 1.1, AA OR = 1.77; p < 0.01), as well as an association between rs25882 in CSF2 and a greater severity of the disease (TC OR = 1.84, CC OR = 3.62; p < 0.01). No association was found between the presence of certain alleles in the SNPs and the plasma levels of the corresponding proteins. CONCLUSIONS: There are genetic polymorphisms related to susceptibility to COPD (rs1818879/A in IL6), as well as to the risk of greater severity of the disease (rs25882/T in CSF2). The presence of the alleles of interest did not significantly affect plasma levels of the codified proteins. PMID- 30296714 TI - Qualitative and quantitative analysis of Yifei Tongluo granules to identify main bioactive components using LC-DAD/MS and pharmacokinetic studies. AB - A standard fingerprint containing twelve common peaks was constructed from ten batches of Yifei Tongluo granules to evaluate batch-to-batch consistency by using HPLC-DAD. Additionally, the corresponding medicinal material attributes of these chemical constituents were analyzed according to the data acquired from the HPLC method and the identification was further carried out using the LC-MS/MS method. Comparing the retention time or accurate mass with previous studies or standards, the common components were tentatively identified in 50 min for ten batches of samples. At the same time, a reliable LC-MS/MS method was established to quantify marker substances simultaneously in 25 min, and the linear relationship of the standard curves was good in the experimental range. The validations of the method were successfully applied to the quality control and pharmacokinetic study. The results obtained from this study suggest that militarine was most abundant and the components in the granules caused pharmacokinetic herb-drug interactions in rats. This study provides a meaningful basis for evaluating the viability of Yifei Tongluo granules for clinical applications. PMID- 30296715 TI - Classification of Romanian medicinal plant extracts according to the therapeutic effects using thin layer chromatography and robust chemometrics. AB - Thin layer chromatography in combination with image analysis and advanced chemometric methods were successfully used to classify the medicinal herbs according to their therapeutic effects and usage. The investigations were conducted using two types of plates (HPTLC Silica gel 60 and HPTLC Silica gel 60 F254) which were evaluated in UV light at 254 and 365 nm. The holistic evaluation of the numerical data corresponding different image processing channels (blue, grey, red, green) was performed by employing appropriate multivariate methods: hierarchical cluster analysis (HCA), principal component analysis (PCA), fuzzy principal component analysis (FPCA) and linear discriminant analysis (LDA) applied to the first relevant principal components. The results obtained by applying LDA method indicate a highly accurate separation of the medicinal herbs within the four groups, in good agreement with therapeutic effects and usage. According to this classification, the best image processing channels were identified for each of the investigated HPTLC plates: blue channel for HPTLC Silica gel 60 F254 (with 92.9% percent of discrimination in case of PCA and FPCA) and respectively red channel for HPTLC Silica gel 60 (with 93.9% percent of discrimination in case of FPCA). The 2D and 3D score scatterplots illustrate also the accurate and reliable discrimination between the four distinct groups. PMID- 30296716 TI - Assessment of the higher order structure of Humira(r), Remicade(r), Avastin(r), Rituxan(r), Herceptin(r), and Enbrel(r) by 2D-NMR fingerprinting. AB - The advent of monoclonal antibody biosimilar products has stimulated the development of analytical methods that can better characterize an important quality attribute, namely the higher order structure (HOS). Here, we propose a simple approach based on heteronuclear 2D NMR techniques at natural abundance for generating spectral fingerprints of the HOS at high resolution. We show that the proposed method can assess the HOS of six therapeutic products, adalimumab (Humira(r)), bevacizumab (Avastin(r)), infliximab (Remicade(r)), rituximab (Rituxan(r)), trastuzumab (Herceptin(r)), and Etanercept (Enbrel(r)). After treatment with immobilized papain, the purified fragments (Fab and Fc) were analyzed by 2D proton-nitrogen and proton-carbon NMR correlations. All Fab and Fc fragments produced high-resolution 2D-NMR spectra from which assessment of their higher order structure can be performed in the context of comparability studies. In particular, the two different sequences of Fc fragments could be unambiguously distinguished. The results show that it is possible to obtain structurally dependent information at amino acid resolution of these important therapeutic agents. PMID- 30296717 TI - Venous thrombosis and breast cancer in older women: Racial differences in risk factors and mortality. AB - BACKGROUND: Risk factors for venous thromboembolism (VTE) in women with breast cancer are not known by race. OBJECTIVES: The purpose of our study was to determine risk factors for VTE and VTE associated mortality in white and black women with breast cancer. PATIENTS AND METHODS: The SEER-Medicare merged database (2000 to 2011) was used for women 65 years and older diagnosed with breast cancer. Stratified by race, logistic regression was used to examine risk factors for VTE and Cox proportional hazards regression was used to evaluate the effect of VTE on mortality. RESULTS: There were 276,028 women 65 years and older with breast cancer. Of those, 6.4% white and 10.1% black women with breast cancer had a diagnosis of VTE. In adjusted analyses by race, risk of VTE increased with each year of age in both white and black cohorts. VTE was independently associated with distant metastasis and coexisting medical conditions in white women and in black women, hypertension, heart failure and hyperlipidemia were determinants of VTE. VTE was not associated with distant metastasis in black women. Tumor size, grade, and receptor status were also not independently associated with VTE risk in either white or black women. VTE accorded a higher risk of death in both white (HR = 1.49, 95% CI, 1.34-1.65) and black women (HR = 1.57, 95% CI, 1.23-2.00) with breast cancer. CONCLUSION: The study identified VTE risk factors and effect of VTE on mortality in white and black older women with breast cancer. PMID- 30296718 TI - Highly selective and sensitive LC-MS/MS quantification of a therapeutic protein in human serum using immunoaffinity capture enrichment. AB - We report the development, validation and application of a liquid chromatography tandem mass spectrometry (LC-MS/MS) bioanalytical method for the determination of a recombinant protein drug candidate, NVS001, in human serum. A unique surrogate peptide, IPAETTIYNR (IPA), was identified to distinguish NVS001 from its endogenous counterpart, i.e., the full length and the C-terminal of protein X in LC-MS/MS. The selection of IPA for the LC-MS/MS determination of NVS001 was supported by the absence of peak responses due to endogenous components in the LC MS/MS chromatograms of the extracted blank human serum samples. The optimal chromatographic separation of IPA from the extracted matrix components was achieved on a Waters Cortecs C18 (100 * 2.1 mm, 2.7 MUm) column using gradient elution with a run cycle time of approximately 7.5 min. The mobile phases were water containing 0.1% formic acid (mobile phase A) and acetonitrile containing 0.1% formic acid (mobile phase B). The method was validated for specificity, sensitivity, matrix effect, recovery, linearity, accuracy and precision, dilution integrity, and stability. The validated assay dynamic range was 10.0 to 1000 ng/mL using a 50 MUL sample volume. The accuracy and precision for the LLOQ (10.0 ng/mL) sample results were within +/-9.2% bias and <=6.0% CV, respectively. From the intra-day and inter-day assay performance evaluations, the precision of the QC sample (30, 500 and 750 ng/mL) results were <=3.5% CV and the accuracy within +/-3.3% bias, respectively. An additional assessment of incurred sample reanalysis (ISR) was conducted to demonstrate the ruggedness and robustness of the assay method. The validated method was successfully implemented in support of a first-in-human study.

AB - Bioequivalence study is highly prized to piroxicam (PIRO), since its generic products have been widely used worldwide. The present work was undertaken to explore the pharmacokinetic behaviors and bioequivalence of two branded PIRO tablets in beagle dogs using the supercritical fluid chromatography tandem mass spectrometry (SFC-MS/MS) method. Here, a fast evaporation-free liquid-liquid extraction (EF-LLE) method using ethyl acetate was developed for extracting PIRO from beagle dog plasma. To improve the response as well as peaks elution and symmetry of analytes, several key factors were investigated including post-column compensation, stationary phase, mobile phase, column temperature, back pressure and flow rate, and finally the analytes were eluted on an ACQUITY UPC2TM BEH 2-EP column (100 * 3 mm, 1.7 MUm) within only 2.5 min in optimal conditions. The performance of the established method was evaluated, good linearity was found over the concentration range of 5-5000 ng/mL (R2 >= 0.994) with a lower limit of quantification (LLOQ) of 5 ng/mL. Accuracy of all quality control (QC) samples were between 96.6% and 99.6% with a satisfactory intra and inter-day precision (RSD values < 6.6%). The proposed rapid, sensitive, user-friendly and high throughput method will be an alternative way for PIRO analysis in biological samples. PMID- 30296721 TI - Reducing inequality summer by summer: Lessons from an evaluation of the Boston Summer Youth Employment Program. AB - Many U.S. cities have implemented Summer Youth Employment Programs (SYEPs) with the hope of improving long-term behavioral, academic, and economic outcomes among program participants, particularly inner-city, low-income, and non-white youth. While recent empirical studies show positive impacts for some outcomes, little is known about program mechanisms and the potential to reduce inequality across groups. Using an embedded randomized control trial, this study evaluates improvements in short-term outcomes for the Boston SYEP based on survey data collected for both treatment and control groups during the summers of 2015, 2016, and 2017. Participants reported increases in community engagement and social skills, job readiness skills, and college aspirations that were significantly different from the control group. In most cases, the largest gains were observed for non-white youth suggesting that the program may have the capacity to reduce inequality across groups. Our hope is that this article will serve as a resource for those seeking to understand how summer jobs programs work and for whom, and to use these findings to strengthen and target the SYEP intervention. We also provide practical lessons learned regarding the development and deployment of our survey instrument to both the treatment and control groups among the youth population.

AB - This article presents a proposal for assessing the progress of least developed countries towards the achievement of the Millennium Development Goals over the period 2000-2015. Composite indices are built to perform spatial and temporal benchmarking relying on the P2 Distance method. The results are contrasted with other indices developed under a multi-criterion approach with a double reference point. The main findings are that all the countries have improved their situation and country disparities have been reduced. Cambodia and Ethiopia have registered the best trends and South Sudan and Timor-Leste show the worse performance. Considering the position in the 2015 ranking, Rwanda and Bhutan performed the best, while Somalia and Chad rank in the last position. Having now reached the end of the Millennium Development Goals period, the gap with respect to the world average indicates that much work remains to be done in the 2030 Agenda for Sustainable Development. PMID- 30296723 TI - Associations between upper extremity injury patterns in side impact motor vehicle collisions with occupant and crash characteristics. AB - INTRODUCTION: Side impact motor vehicle collisions (MVC) represent a significant burden of mortality and morbidity caused by automotive injury within the United States. The objective of this study was to evaluate the relationship between upper extremity (UE) injury patterns and contact sources in side impact MVC with occupant and crash variables. METHODS: Crash Injury Research and Engineering Network data obtained from 1998 to 2012 were used to evaluate UE injuries in side impact crashes. First row drivers and passengers that were at least 16 years old with complete crash information were included. Side impact crashes were defined to have an area of deformation to the side of the vehicle and a principal direction of force between 60 degrees and 120 degrees or 240 degrees and 300 degrees . Injuries were stratified by type, anatomic location, and Abbreviated Injury Scale (AIS) severity. Occupant variables included age, sex, height, weight, body mass index, and Injury Severity Score. Vehicle and crash variables included in the analysis were change in vehicle velocity at the time of impact, maximum door intrusion, maximum B-pillar intrusion, seat track position, belt use, vehicle type, impact type, and injury source. Statistical analysis of the UE injury data included descriptive statistics, linear regression analyses with occupant variables, and logistic regression analyses with vehicle and crash variables. RESULTS: There were 903 UE injuries among 408 case occupants. The most common injury type was soft tissue injury (72.5%). The majority of fractures were proximal to and including the humerus (70.3%) with the clavicle being the most common fracture location (N = 89). AIS 2+ UE injuries were associated with a significantly higher mean occupant Injury Severity Score than AIS 1 UE injuries (p = 0.01). Contact with the door was the leading cause of UE injury (34.2%). The odds (OR [95% confidence interval], p-value) of an AIS 2+ UE injury due to contact with the B-pillar (5.3 [3.1, 9.1], <0.0001), door (1.9 [1.3, 2.7], 0.0006), and steering wheel/assembly (2.7 [1.1, 6.3], 0.03) were significantly higher than all other injury sources combined. Scapula fractures were significantly associated with rearward seat track positions (1.46 [1.04, 2.05], 0.03). CONCLUSIONS: This study provides insight into UE injury patterns in side impact MVC. The clavicle was the most common UE fracture location. Contact with the door resulted in the highest number of UE injuries and the B-pillar resulted in the most severe injuries. Additionally, exposure to greater B-pillar intrusion was associated with increased odds of scapula and clavicle fractures in side impacts. PMID- 30296724 TI - Sex-specific trajectories of measures of cardiovascular health during childhood and adolescence: A prospective cohort study. AB - BACKGROUND AND AIMS: Sex differences in measures of cardiovascular health in adults are well documented. However, the sex-specific aetiology of cardiovascular health across childhood and adolescence is poorly understood. METHODS: We examined sex differences in trajectories of 11 measures of cardiovascular health from birth to 18 years, in a contemporary birth cohort study in England (N participants per outcomes: 662-13,985, N repeated measures per outcome: 1,831 112,768). Outcomes were measured over varying time spans from birth or mid childhood to age 18 and with different numbers of repeated measures per outcome. Analyses were performed using fractional polynomial and linear spline multilevel models. RESULTS: Females had higher mean BMI, height-adjusted fat mass, pulse rate, insulin, triglycerides, and non-high-density lipoprotein cholesterol (HDL c) and lower mean height-adjusted lean mass from birth or from mid-childhood to age 18. For example, mean non-HDL-c was 0.07 mmol/l (95% confidence interval (CI), 0.04, 0.10) higher in females compared with males at birth. By age 18, this difference persisted and widened to 0.19 mmol/l (95% CI, 0.16, 0.23) higher non HDL-c in females compared with males. Females had lower levels of glucose from mid-childhood and developed lower systolic blood pressure and higher HDL-c from mid-adolescence onward. For example, females had 0.08 mmol/l (95% CI, 0.05, 0.10) lower mean glucose compared with males at age seven which widened to a difference of 0.22 mmol/l (95% CI, 0.25, 0.19) at age 18. CONCLUSIONS: Sex differences in measures of cardiovascular health are apparent from birth or mid-childhood and change during early life. These differences may have implications for sex specific disease risk in future adult populations. PMID- 30296725 TI - The first competency based framework in genetics/genomics specifically for midwifery education and practice. AB - This paper details a competency framework to help address the need for structured guidance around genetic and genomic education and training for midwives. A one day expert panel consensus meeting was convened to review and revise a previously published joint framework for nurses, midwives and health visitors. Fifteen midwives from practice, management, education and policy and three genetic counsellors (two with midwifery backgrounds) attended. An in-depth knowledge of genetics/genomics was not a requirement. Personal narratives covering a range of experiences across the pre- and post-natal periods were used to stimulate discussion and debate. Identified themes were mapped to the original framework to identify gaps and differences. Inclusion of additional themes into the new framework was voted upon. All original competencies were found to be valid but required amendment in order to focus specifically on the role of the midwife and the needs of the mother, child and wider family. Revisions have resulted in a framework that is more directive and which addresses the time-critical nature of information-giving, decision-making, testing and referral that are crucial components of midwifery practice. Learning outcomes and practice indicators offer educators and trainers a means of developing student/staff knowledge and skills over time and with increasing experience. PMID- 30296726 TI - Evaluation of student perception of the Team-based Learning method (APA-TBL): Instrument construction and validation. AB - Team-based learning (TBL) is an educational strategy based on learning teams. Despite the advantages identified in the TBL literature, student perceptions must be better investigated using valid, reliable instruments. This study constructed and validated an instrument to evaluate student perceptions of the TBL method. Content and appearance assessment, construct validation and reliability analysis were performed. A total of 246 undergraduate nursing and medical students from a private institution in Sao Paulo, Brazil, participated in the study. After content validation, the instrument had 24 items distributed in five dimensions. Based on exploratory factor analysis, the instrument was appropriate, and the items were regrouped in four dimensions, with Cronbach's alpha values over 0.70. The Student Perception Evaluation of the TBL method (Avaliacao da Percepcao do Aluno-Team-Based Learning - APA-TBL) is an instrument with strong validity indicators. After validation, the revised instrument reflected that the student's perspective of method evaluation is not focused on TBL's formal execution but on the involved agents, their interaction and their influence on one another. PMID- 30296727 TI - Facilitating affective elements in learning - In a palliative care context. AB - The aim of this study was to explore ways clinical supervisors facilitate the learning of the affective elements of professional competence in a clinical palliative care environment. The secondary aim was to advocate for and raise awareness of the importance of the affective domain in medical education. A clinical palliative care learning environment has been reported to be emotionally challenging. The affective and transformative learning processes taking place requires special support. However, little is known about how clinical supervisors facilitate this learning processes. A qualitative, explorative study was designed to capture supervisors' perceptions of their supervision using semi-structured interviews. Six experienced clinical supervisors working within a palliative care context were recruited using convenience sampling. Data were analyzed using inductive content analysis. The affective elements were viewed as essential for learning, clinical supervision, and professional competency. Supervisors use a variety of different ways of facilitation. Four main themes were identified; building a relationship, creating space for learning, creating a pedagogical environment, and Mirroring. PMID- 30296728 TI - Space quantization between the object and image spaces of a microscopic stereovision system with a stereo light microscope. AB - Microscopic stereovision systems with a stereo light microscope have been used for quantized observations and measurements in microscopy fields. These applications depend on a quantization mathematical relationship between the object space and the image space. In this article, a novel, practical space quantization method was proposed. It was derived from two defined base cell matrices. First, it captured a series of stereo images of markers moving in various directions through the object space. The world and image coordinates of markers were acquired, stored and used to create the two base cell matrices. Next, a space quantization relationship between the object space and the image space was derived from analysis of the two base cell matrices. Finally, if two matching points located in the image space were given, the world coordinates of their object point could be calculated by the above space quantization relationship. The results show that this method of quantizing the two spaces could achieve a positioning precision of approximately +/-5 MUm in the horizontal direction and approximately +/-10 MUm in the vertical direction. It has a very simple expression, but it is more practical and efficient than other traditional projection methods. In addition, it has a better performance and can be widely used in several microscopy fields, such as microscopic shape reconstruction, micromanipulation, microassembly, and microinjection. PMID- 30296729 TI - Associations of stress, self-esteem, and collective efficacy with flow in simulation among nursing students: A descriptive cross-sectional study. AB - BACKGROUND: Simulation-based learning was developed to enable nursing and medical students to obtain clinical experience in a safe and controlled environment. The extent to which students concentrate in simulation situations can influence their educational outcomes. However, there are no studies yet on the factors that influence flow in simulation practice. Understanding which factors influence flow might help in achieving better simulation-based learning outcomes. OBJECTIVES: The purpose of this study was to identify the factors related to flow in simulation practice, including stress, self-esteem, and collective efficacy. DESIGN: This was a descriptive cross-sectional study. SETTING: A university in South Korea during the 2015 academic year. PARTICIPANTS: This study was conducted with 84 senior nursing students. Their average age was 23 years old and >90% were female. METHODS: The stress, self-esteem, and collective efficacy of senior nursing students were measured before simulation practice, while flow in simulation practice was measured after simulation. RESULTS: Flow during simulation practice was positively correlated with self-esteem and collective efficacy, but negatively correlated with stress. Furthermore, only collective efficacy was a significant predictor of flow during simulation. CONCLUSIONS: Nursing education must be oriented to help emphasize collective efficacy to improve students' outcomes from simulation-based learning. PMID- 30296730 TI - Using high fidelity simulation to increase nursing students' clinical postpartum and newborn assessment proficiency: A mixed-methods research study. AB - OBJECTIVE: The objective of this study was to explore the benefits of using High Fidelity Simulators (HFS) to teach maternal postpartum and newborn assessment skills to student nurses before they interacted with actual hospital patients. DESIGN: This descriptive, observational study employed a mixed-method design using a Qualtrics online survey instrument. SETTING: The study was set at a Midwestern university. PARTICIPANTS: The study used a convenience sample of third year BSN nursing students (n = 132). METHODS: After participating in an HFS experience and completing a maternity clinical rotation, students took an online Qualtrics survey evaluating the benefits and drawbacks of the HFS experience. RESULTS: Students valued the HFS experience at an average score of 3.82 on a Likert Scale of 1-5. Open-ended questions identified three themes: psychomotor learning leading to skill acquisition, affective learning, and simulation restructuring to provide more time, better instructor preparation, and smaller groups. CONCLUSION: This study's data supports the use of HFS to enhance nursing care and education, with special attention given to instructional consistency. Practicing new assessment skills in a non-threatening, safe environment gives students expertise and confidence while promoting the development of critical thinking skills. PMID- 30296731 TI - Assessing the educational impact of the dementia champions programme in Scotland: Implications for evaluating professional dementia education. AB - Increasing numbers of people with dementia are living longer with a higher likelihood of requiring hospital care for physical conditions including falls, infections and stroke (Boaden, 2016). However, the literature is replete with descriptions of poor care and hospital care experiences that have fallen well below the expectations of people with dementia, their families and friends. Although poor care is unacceptable, it is unsurprising given that dementia education for health and social care professionals is often inadequate and inconsistent. This results in most healthcare staff being ill-equipped and lacking the confidence to work with people living with dementia. The first of Scotland's National Dementia Strategies committed to "improve the response to dementia in general hospital settings including alternatives to admission and better planning for discharge" (Scottish Government, 2010). The educational response was the commissioning of the Dementia Champions programme. Since 2011, the programme has developed over 800 health and social care professionals working in general hospital and related settings to be change agents in dementia care. This article will outline the theoretical underpinning of the programme and present pooled results from four cohorts (2014-2017) (n = 524). A repeated measure design (pre and post programme) was used to measure attitudes towards people with dementia; self-efficacy and knowledge of dementia. The findings suggest that the education had a statistically significant positive effect on all intended outcomes, indicating the potential for practice change. We discuss these findings in relation to the literature, and respond to the calls for high quality evaluation to measure the effectiveness of dementia education, the challenges and potential directions for measuring educational effectiveness and capturing transfer of learning. PMID- 30296732 TI - Use of eHealth and mHealth technology by persons with multiple sclerosis. AB - BACKGROUND: Health communication has evolved substantially over the last few years as the field of electronic health (eHealth) technologies has emerged. It is unknown what demographic and clinical characteristics are associated with use of eHealth technologies in MS. As these technologies are more widely adopted in health settings, it is important that health care providers understand who is using them, and to recognize potential disparities if they exist. OBJECTIVE: We aimed to examine the use of eHealth technologies among persons with multiple sclerosis (MS), including the adoption of mobile Health (mHealth) applications (apps) and telehealth, perceived benefits of using mHealth apps, and sociodemographic and clinical characteristics associated with use of these technologies. METHODS: In the spring 2017, we surveyed participants in the North American Research Committee on Multiple Sclerosis (NARCOMS) Registry about their use of eHealth technologies using questions adapted from the Health Information National Trends (HINTS) 4 Cycle 4 survey. Participants reported their internet use, electronic devices used, use of health related software apps and perceived benefits from using those apps, and their interest in exchanging medical information with a health care professional electronically. We used descriptive statistics to report use of eHealth technologies and multivariable logistic regression to evaluate factors associated with use of electronic devices, use of mHealth apps, telehealth use, and perceived benefits of using mHealth apps. RESULTS: Of 6423 participants included in the analysis most participants were female, and white, with a mean (SD) age of 59.7 (10.1) years. Overall, 5408 (84.2%) had exchanged medical information with a health professional most often using a secure online portal (1839, 28.6%), followed by email (1327, 20.7%). of the 5529 smartphone and tablet users, 2556 (46.2%) used a mHealth app. Factors associated with a higher likelihood of reporting use of smartphones or tablets, mHealth apps and with perceived benefits of using these apps included online survey response, younger age, having comorbidities, and higher income and education levels. CONCLUSION: Use of eHealth technologies is common in the MS population and facilitates the exchange of health care information with providers. Use of mHealth apps is perceived to have health benefits. However, use of eHealth and mHealth technologies varies substantially with sociodemographic factors, and health care providers need to be aware of these disparities as these technologies are increasingly leveraged in health care settings. PMID- 30296733 TI - In vivo combined treatment of rats with ivermectin and aged garlic extract attenuates ivermectin-induced cytogenotoxicity in bone marrow cells. AB - Ivermectin (IVM) is widely used in human and veterinary medicine for the control of parasitic infections. Researches revealed new avenues of medicinal applications of IVM as an antiviral and an anticancer agent. Very little is known about the genotoxic potential of IVM and the available literature is contradictory. The objective of this study was to evaluate the possible genetic damage caused by IVM. Male Sprague Dawley rats were intraperitoneally given IVM at doses between 0.2 mg and 3.2 mg/kg body weight (b. w). Percentages of mitotic and aberrant bone marrow cells were followed. The results indicated that IVM by itself, at doses higher than the recommended dose, induced significant levels of cytogenetic toxicity. To this end, we decided to investigate the potential use of combination of varying doses of aged garlic extract (AGE); 300, 600 and 1200 mg/kg b w and the minimum detectable toxic (MDT) dose of IVM; 0.4 mg/kg. A powerful capacity of AGE to reduce IVM cytogenetic effects was demonstrated. Overall, the data prove the safety of IVM at the recommended dose and provide a strong scientific evidence for superior protection of AGE against possible cytogenotoxic side effects of IVM, confirming the existence of a meaningful therapeutic window. PMID- 30296734 TI - Making a 'JUMP' from paediatric to adult healthcare: A transitional program for young adults with chronic neurological disease. AB - BACKGROUND: "JUMP" is a multidisciplinary program based at the Pitie-Salpetriere Hospital Paris that transitions young adults with chronic neurological conditions from paediatric to adult healthcare. Transitional care programs have been shown to improve medical, educational and psychosocial outcomes for adolescent patients. METHODS: Demographic details and health-related variables of all patients referred to the JUMP program were collected. Satisfaction outcome measures were the 18-item On Your Own Feet Transfer Experience Scale (OYOF-TES) and a visual analogue scale, which assessed overall satisfaction with the transfer process. Scales were sent to JUMP patients attending the JUMP day hospital (n = 94) and their parents (n = 94). RESULTS: Since its inception, 111 patients have been seen in the JUMP program. Nine neurological clinical syndromes and four main underlying etiologies were identified. Approximately half of all questionnaires and scales (86/188) sent to patients and parents were returned. Eighty-nine percent of patients and 91% of parents were very satisfied with their transfer experience. There was a strong, positive correlation between patient and parent satisfaction [r = 0.910; p < 0.0001]. CONCLUSION: The JUMP program which is rooted in a multidisciplinary and coordinated approach to transitional care encompasses a broad range of neuro-pathologies. Overall, satisfaction levels were high amongst patients within the program, and their parents. The key role played by the coordination nurse specialists throughout the transfer process is a likely key determinant in satisfaction levels. PMID- 30296736 TI - Comparative efficacy and safety of tyrosine kinase inhibitors for chronic myeloid leukaemia: A systematic review and network meta-analysis. AB - BACKGROUND: The pharmacotherapy of chronic myeloid leukaemia (CML) is mainly based on tyrosine kinase inhibitors (TKIs). The aim of this study was to compare the efficacy and safety of all TKIs in CML patients. METHODS: We conducted a systematic review with network meta-analysis (NMA) of randomised controlled trials (RCTs), including imatinib, nilotinib, dasatinib, bosutinib, radotinib and ponatinib. Searches were performed in PubMed, Scopus, Web of Science and SciELo (March 2018). The NMAs were built for six outcomes at 12 months: complete cytogenetic response (CCyR), major cytogenetic response (MCyR), deep molecular response, major molecular response (MMR), complete haematologic response and incidence of serious adverse events. We conducted rank order and surface under the cumulative ranking curve (SUCRA) analyses. RESULTS: Thirteen RCTs were included (n = 5079 patients). Statistical differences were observed for some comparisons in all outcomes. Imatinib 400 mg was considered the safest drug (SUCRA values of 10.3%) but presented low efficacy. Overall, nilotinib 600 mg was superior to the other TKI in efficacy (SUCRA values of 61.1% for CCyR, 81.0% for MMR, 90.0% for MCyR); however, no data on its safety profile at 12 months were reported. INTERPRETATION: Our results suggest that nilotinib should be upgraded to first-line therapy for CML, although further cost-effectiveness analyses, including the new TKI (i.e., ponatinib, radotinib), are needed. PMID- 30296735 TI - Pain intensity as a moderator of the association between opioid use and insomnia symptoms among adults with chronic pain. AB - OBJECTIVE: Research documenting the impact of opioid use on sleep among individuals with chronic pain has been mixed. This study aimed to determine if pain intensity moderates the association between opioid use and insomnia symptoms among adults with comorbid symptoms of insomnia and chronic widespread pain. METHODS: Participants (N = 144; 95% female; mean age = 51.6, SD = 11.4) completed assessments of insomnia symptoms, pain and use of sleep/pain medication. Multiple regression was used to determine if pain intensity moderates the association between opioid use (yes/no) sleep onset latency (SOL), wake after sleep onset (WASO), sleep quality, or time in bed. Analyses controlled for gender, symptoms of sleep apnea, symptoms of depression, use of sleep medication (yes/no), and use of non-opioid pain medication (yes/no). RESULTS: Stronger pain intensity was associated with longer self-reported WASO and worse sleep quality, independent of opioid use. Conversely, opioid use was associated with longer time in bed, independent of pain intensity. Opioid use and pain intensity interacted in the prediction of SOL, such that opioid use (vs. non-use) was associated with longer SOL in the context of mild but not moderate to severe pain intensity. CONCLUSIONS: Opioid use was associated with more difficulty falling asleep among adults with chronic pain; however, this cross-sectional effect was only significant among those reporting lower pain intensity. Authors speculate that this effect is masked among those with severe pain because the pain-related sleep debt they acquire throughout the night then facilitates sleep onset the next day. PMID- 30296737 TI - Understanding mode of action can drive the translational pipeline towards more reliable health benefits for probiotics. AB - The different levels of knowledge described in a translational pipeline (the connection of molecular mechanisms with pre-clinical physiological and human health effects) are not complete for many probiotics. At present, we are not in a position to fully understand the mechanistic basis of many well established probiotic health benefits which, in turn, limits our ability to use mechanisms to predict which probiotics are likely to be effective in any given population. Here we suggest that this concept of a translation pipeline connecting mechanistic insights to probiotic efficacy can support the selection and production of improved probiotic products. Such a conceptual pipeline would also provide a framework for the design of clinical trials to convincingly demonstrate the benefit of probiotics to human health in well-defined subpopulations. PMID- 30296738 TI - An autopsy report of accidental burial in a beach sand hole. AB - We present a 23-year-old married couple who died by accidental burial in a beach sand hole. The victims fell into a hole that had been covered with a plastic sheet, and were buried suddenly by sand that had been piled on the top of the sheet. At autopsy, facial congestion; petechial hemorrhages in the conjunctivae and the oral mucosa; skin petechiae at the face, neck and upper chest; congestion and hemorrhages in the cervical lymph nodes; and some minor hemorrhages in the cervical muscles were found in both victims. Little sand was evident in the airway, while sand debris was found in the oral cavity. Prior reports suggest that aspiration of sand is a major contributing factor in asphyxia after accidental burials. However, neck and chest compression and face coverage by sand masses could induce lethal asphyxia without airway obstruction caused by sand aspiration. Asphyxia was deemed to be the cause of death in both individuals and was considered to result from chest compression by sand. In addition, compression of the neck may also have contributed to asphyxia. In this instance, the sand beach hole was excavated for recreational purposes. The potentially life threatening implications of beach sand hole excavations should be recognized and highlighted to prevent lethal accidents such as those described in this report. PMID- 30296739 TI - In vivo hepatocellular expression of interleukin-22 using penetratin-based hybrid nanoparticles as potential anti-hepatitis therapeutics. AB - Hepatocellular injury is the pathological hallmark of hepatitis and a crucial driver for the progression of liver diseases, while the treatment options are commonly restricted. Interleukin-22 (IL-22) has attracted special attention as a potent survival factor for hepatocytes that both prevents and repairs the injury of hepatocytes through activation of STAT3 signaling pathway. We hypothesized that the ability to generate potent expression of IL-22 locally for the treatment of severe hepatocellular injury in hepatitis was a promising strategy to enhance efficacy and overcome off-target effects. Accordingly, we developed a polypeptide penetratin-based hybrid nanoparticle system (PDPIA) carrying IL-22 gene by a self assembly process. This nanocomplex modified with penetratin featured direct translocation across the cellular or endosomal membrane but mild zeta-potential to facilitate the high cellular internalization and endosomal escape of the gene cargos as well as scarcely Kupffer cells uptake. More importantly, PDPIA afforded preferential liver accumulation and predominant hepatocytes internalization following systemic administration, which showed pharmacologically suitable organ and sub-organ-selective properties. Subsequent studies confirmed a considerable protective role of PDPIA in a model of severe hepatitis induced by concanavalin A, evidenced by reduced hepatocellular injury and evaded immune response. The locally expressed IL-22 by PDPIA activated STAT3/Erk signal transduction, and thus promoted hepatocyte regeneration, inhibited reactive oxygen species (ROS) accumulation as well as prevented the dysfunction of mitochondrial. In addition, this system did not manifest side effects or systemic toxicity in mice. Collectively, the high versatility of PDPIA rendered its promising applications might be an effective agent to treat various hepatic disorders. PMID- 30296740 TI - Long-term seizure outcome in pediatric patients with focal cortical dysplasia undergoing tailored and standard surgical resections. AB - PURPOSE: Focal cortical dysplasia (FCD) is the major cause of focal intractable epilepsy in childhood. Here we analyze the factors influencing the success of surgical treatment in a large cohort of children with histologically ascertained FCD. METHOD: A retrospective study of the effects of FCD type, surgical intervention, and age at surgery in a pediatric cohort. RESULTS: A total of 113 patients (71 male; mean age at surgery 10.3 years; range 0-18) were analyzed; 45 had undergone lesionectomy, 42 lobectomy, 18 multi-lobectomy, and eight hemispherotomy. Complete seizure control (Engel Ia) was achieved in 56% after two years, 52% at five years, and 50% at last follow-up (18-204 months). Resections were more extensive in younger patients (40% of the surgeries affecting more than one lobe in patients aged nine years or younger vs. 22% in patients older than nine years). While resections were more limited in older children, their long term outcome tended to be superior (42% seizure freedom in patients aged nine years or younger vs. 56% in patients older than nine years). The outcome in FCD I was not significantly inferior to that in FCD II. CONCLUSIONS: Our data confirm the long-term efficacy of surgery in children with FCD and epilepsy. An earlier age at surgery within this cohort did not predict a better long-term outcome, but it involved less-tailored surgical approaches. The data suggest that in patients with an unclear extent of the dysplastic area, later resections may offer advantages in terms of the precision of surgical-resection planning. PMID- 30296741 TI - A biological, fluorescence and computational examination of synthetic coumarin derivatives with antithrombotic potential. AB - BACKGROUND: Scientists still look for new drugs, which have anticoagulant properties. This is so important because existing anticoagulant drugs give many side effects, for example major bleeding. In this study we examined nine coumarin derivatives - candidates to be future antithrombotic drugs, which were synthetized and crystallized in our previous paper. METHODS: Here we show the fluorescence and fluorescence quenching of coumarin derivatives with di- or trimethoxybenzylamine moieties in C-3 position. All nine compounds were checked by lactate dehydrogenase assay to examine their cytotoxic activity on hepatic cells. We also investigated the other biological properties (bioactivity, drug likeness and blind docking) using computational tools. Lipophilicity coefficient logP of all obtained compounds was determined using by RP-TLC and compared to theoretical predictions. RESULTS: The obtained coumarins exhibited low lipophilic character. The substances bound with HSA and did not demonstrate cytotoxicity against isolated liver cells. The most interesting compound (3b) possessed two methoxy- group in 2- and 4-position in benzene ring, ability to interact with two HSA binding sites and probably smaller steric hindrance in comparison to other synthesized derivatives. CONCLUSIONS: Our present study shows that after examination of fluorescence, cytotoxic activity, lipophilicity, theoretical bioactivity, drug-likeness and blind docking of our synthesized compounds they have potential as antithrombotic medicines and may be candidates to be drugs after further studies. PMID- 30296742 TI - The association between inflammatory markers (iNOS, HO-1, IL-33, MIP-1beta) and depression with and without posttraumatic stress disorder. AB - BACKGROUND: Both major depression and posttraumatic stress disorder (PTSD) are characterized by inflammation, increased concentration levels of proinflammatory cytokines, decreased neurogenesis followed by neuroprogression, as well as mitochondrial and the hypothalamic-pituitary-adrenal axis dysfunction. Elevated levels of oxidative stress caused by an increased activity of prooxidants over antioxidants are also observed. Based on several reports, depressive episodes can lead to the sensitization of immune-inflammatory pathways. Thus, depression, PTSD, and depression comorbid with PTSD are associated with immune-inflammatory markers. The study aimed at evaluating concentration levels of iNOS, HO-1, IL-33, and MIP-1beta in depression with and without PTSD. METHODS: A total number of participants enrolled in the study was 460. Out of them, 420 subjects with various levels of depression severity constituted the study group (210 males and 210 females), and 40 subjects (20 males and 20 females) constituted the control group. Each study group comprised 60 patients (30 males and 30 females) with mild depression (MD), moderate depression (MOD), severe depression (SeD), MD and PTSD (MD + PTSD), MOD and PTSD (MOD + PTSD), SeD and PTSD (SeD + PTSD), and with PTSD alone. At 7:00 a.m., all patients had serum concentrations of iNOS, HO-1, IL-33, MIP-1beta determined using ELISA. RESULTS: Both depression exacerbation and PTSD comorbidity led to elevated levels of iNOS, HO-1, IL-33, and MIP-1beta. CONCLUSION: Depression both with and without PTSD leads to elevated levels of inflammation and an oxidant/antioxidant imbalance. Alterations in both cytokines and oxidative stress are related to the mechanisms responsible for the development of depressive symptoms.

AB - BACKGROUND: Selenium (Se) is an essential micronutrient for animals and humans used in the prevention or treatment of cancer. Selol is a mixture of selenitetriglycerides, containing Se(IV). It does not exhibit mutagenic activity and is less toxic than inorganic sodium selenite containing Se(IV). The antioxidant properties of the Selol were demonstrated using the blood of healthy animals. The aim of the study was to evaluate Selol as a Se supplement by determining the effect of its administration on the Se level and the antioxidant status in the tissues. METHODS: We examined the effect of long-term (28-day) Selol 5% supplementation on the activity of antioxidant enzymes, including the main selenoenzymes in healthy mice organs, such as liver, brain, lungs, and testis. Enzyme activities of the tissue homogenates and the concentration of malondialdehyde (MDA) as a biomarker of oxidative stress were measured using spectrophotometric methods. The selenium concentrations in the tissues were determined by inductively coupled plasma mass spectrometer (ICP-MS) as well. RESULTS: A significant increase in glutathione peroxidase, thioredoxin reductase, and glutathione S-transferase activity as well as the MDA concentration was observed in most of the studied tissues during the Selol 5% supplementation. CONCLUSIONS: Long-term supplementation with the new Se(IV) compound - Selol 5% significantly affects the activity of antioxidant enzymes and the redox state in healthy mice organs. In the healthy population Selol 5% seems to be a promising new antioxidant compound. PMID- 30296745 TI - A novel non-starch based cationic polymer as flocculant for harvesting microalgae. AB - This work intends towards the preparation of different grades of cationic locust bean gum biopolymer (CLBG) through the incorporation of 2,3 epoxypropyltrimethylammonium chloride (GTMAC) on to the pristine locust bean gum (LBG) biopolymer. Among them the best grade was further selected, characterized and their flocculation efficacy was evaluated towards harvesting of three different indigenous isolated green microalgae viz. Chlorella sp. NCQ, Micractinium sp. NCS2 and Scenedesmus sp. CBIIT(ISM). Flocculation efficiency of 96.68%, 96.64%, and 97.42% were obtained for Chlorella sp. NCQ, Micractinium sp. NCS2 and Scenedesmus sp. CBIIT(ISM) at an optimum dosage of 55, 40, and 30 ppm respectively. Thus CLBG was proven to be an efficient flocculant towards harvesting of green microalgae than its natural form. PMID- 30296744 TI - Virome definition in cerebrospinal fluid of patients with neurological complications after hematopoietic stem cell transplantation. AB - BACKGROUND: Neurological complications (NC) in allogeneic hematopoietic stem cell transplant (HSCT) recipients lead to long-term sequelae and result in significant morbidity and mortality. Since risk factors for NC include viral infection or reactivation, virome inspection after HSCT might be helpful to the clinical management of patients after HSCT. OBJECTIVES AND STUDY DESIGN: In this study we investigated whether any viruses are found in association with NC after HSCT. For this purpose, unbiased next generation sequencing (NGS) was used to characterize nucleic acid (NA) content in cerebrospinal fluid (CSF) taken at time of NC in 35 HSCT patients. Virome definition in CSF from non-transplanted subjects (controls) was also tested to define the commensal flora. RESULTS AND CONCLUSIONS: A higher number of reads/contigs mapped to viruses in patients compared to the controls (7,626 vs 235). Besides bacteriophages, Torque teno virus (TTV) was also identified in both controls and patients. Interestingly, a significantly higher number of TTV-like sequences was detected in the patient samples (7,236 vs 9), showing similarities to distinct genotypes; 3/2,575, 2/1,692 and 2/2,969 contigs/reads mapped to TTV11, TTV13 and Torque teno midi virus, respectively. In conclusion, unbiased NGS demonstrated to be a suitable approach to characterize the virome in samples containing limiting amounts of NA. The higher TTV levels and genetic diversity found in CSF of subjects with NC after HSCT might suggest a possible association between TTV reactivation and the disorder. However, further studies are needed to evaluate the possible role of TTV on NC in HSCT patients. PMID- 30296746 TI - Recovery of chlorophylls from spent biomass of Arthrospira platensis obtained after extraction of phycobiliproteins. AB - Extraction of chlorophylls has received scant attention or priority over phycobiliproteins from Arthrospira platensis. In fact extraction of chlorophylls from spent biomass (left after extraction of phycobiliproteins which goes as waste or underutilized) on drying, will improve the economics of the overall downstream processing. Ethanol (yield 5.75 mg/g, db), being a food grade solvent, was preferred over acetone and dimethyl sulfoxide in spite of their slightly better yields (5.85 mg/g, db). The best conditions were 100% concentration of ethanol, 1:8 S/L ratio, pH 6, 50 degrees C temperature and 1 h extraction time. An increase of 125% in yield besides reduction of 83.3% in extraction time (from 6 to 1 h) could be achieved at standardized conditions. Low-Humidity drying was observed to be a possible alternative to freeze drying for drying of spent biomass. Ultrasonication as pre-treatment and ethanol as solvent were found effective for extraction of chlorophylls from dry spent biomass. PMID- 30296747 TI - Effect of nanosecond pulsed electric field treatment on cell proliferation of microalgae. AB - Photoautotrophic microalgae based biorefinery concepts are currently not competitive compared to other established production systems. Therefore, innovative upstream processes need to be developed to increase the competitiveness of photoautotrophic microalgae biorefinery concepts. Abiotic sub lethal stress induction via nanosecond pulsed electric field (nsPEF) treatment might be a viable process to increase the efficiency of photoautotrophic microalgae cultivation. In this work, an increased cell growth after nsPEF treatment was observable. Application of nsPEF to highly proliferating cells in a repetitive process resulted in a statistical significant increase in cell growth (p = 0.009). The effect was most pronounced after five days wherefore cellular structures and processes were analyzed to reveal a possible mechanism. Within this work, a protocol for increased cell proliferation with a possible mechanism was derived, which improves competitiveness of photoautotrophic microalgae biorefineries in the future. However, based on the derived mechanism, the results are also relevant for other microorganisms. PMID- 30296748 TI - Valorisation of digestate from biowaste through solid-state fermentation to obtain value added bioproducts: A first approach. AB - Digestate from biowaste was assessed as a potential source of bioproducts of commercial and industrial interest through solid-state fermentation. The targeted bioproducts were hydrolytic enzymes (cellulases and proteases from autochthonous microbiome), biosurfactants (sophorolipids produced from Starmella bombicola) and biopesticides (produced from Bacillus thuringiensis). Low cellulase production was observed within the range of 0.5-1.5 FPU g-1 DM while protease production showed two discrete peaks of 66 +/- 8 and 65 +/- 3 U g-1 DM at 3.5 and 48 h, respectively. Low sophorolipids production was also obtained, with a maximum yield of 0.02 g g-1 DM using hygienised digestate supplemented with external sugar and fat sources. Biopesticides produced by B. thuringiensis were successfully at 72 h of operation, reaching a maximum spore production of 8.15 +/ 0.04 (107) CFU g-1 DM and 2.85 +/- 0.22 (107) CFU g-1 DM using sterile and hygienised digestate, respectively. These biopesticides could contribute to the substitution of chemically produced pesticides, moving towards a sustainable digestate management in a circular economy scheme. PMID- 30296749 TI - Patients' perceptions and ICU clinicians predictions of quality of life following critical illness. AB - PURPOSE: To determine how patients perceive their quality of life (QOL) six months following critical illness and to measure clinicians' discriminative accuracy of predicting this outcome. MATERIALS AND METHODS: This prospective cohort study of intensive care unit (ICU) survivors asked patients to report their QOL strictly at six months compared to one month before their critical illness as better, the same, or worse. ICU physicians and nurses made six-month QOL predictions for these patients. RESULTS: Of 162 critical illness survivors, 33% (n = 53) of patients reported six-month QOL as better, 33% (n = 54) the same, and 34% (n = 55) worse. Abnormal cognition and inability to return to primary pastime or original place of residence (p < .05 for all) were associated with worse self-reported QOL at six months in multivariable regression. Predictions of patient perceptions of QOL at six months were pessimistic and had low discriminative accuracy for both physicians (sensitivity 56%, specificity 53%) and nurses (sensitivity 49%, specificity 57%). CONCLUSIONS: Among survivors of critical illness, one-third each reported their six-month post-ICU QOL as better, the same, or worse. Self-reported six-month QOL was associated with six-month function. ICU clinicians should use caution in predicting self-reported QOL, as discriminative accuracy was poor in this cohort. PMID- 30296750 TI - Highly visible sepsis publications from 2012 to 2017: Analysis and comparison of altmetrics and bibliometrics. AB - PURPOSE: We sought to delineate highly visible publications related to sepsis. Within these subsets, elements of altmetrics performance, including mentions on Twitter, and the correlation between altmetrics and conventional citation counts were ascertained. MATERIALS AND METHODS: Three subsets of sepsis publications from 2012 to 2017 were synthesized by the overall Altmetric.com attention score, number of mentions by unique Twitter users, and conventional citation counts. For these subsets, geolocated Twitter activity was plotted on a choropleth, the lag between publication date and altmetrics mentions was characterized, and correlations were examined between altmetrics performance and normalized conventional citation counts. RESULTS: Of 57,152 PubMed query results, Altmetric.com data was available for 28,344 (49.6%). The top 50 publications by Altmetric.com attention score and Twitter attention represented a mix of original research and other types of work, garnering attention from Twitter users in 143 countries that was highly contemporaneous with publication. Altmetrics performance and conventional citation counts were poorly correlated. CONCLUSIONS: While unreliable to gauge impact or future citation potential, altmetrics may be valuable for parties who wish to detect and drive public awareness of research findings and may enable researchers to dynamically explore the reach of their work in novel dimensions. PMID- 30296751 TI - Pharmacoinformatics analysis of merbarone binding site in human topoisomerase IIalpha. AB - Merbarone is a derivative of thiobarbituric acid, possessing catalytic inhibitory potential against human topoisomerase IIalpha (hTopoIIalpha). Merbarone was reported to inhibit DNA cleavage by hTopoIIalpha. It is important to understand the molecular mechanism of hTopoIIalpha inhibition by merbarone, as these details guide the rational design of new ligands. In this work, a systematic pharmacoinformatics analysis has been reported to analyze the merbarone hTopoIIalpha interactions and to identify merbarone analogs as potential hTopoIIalpha inhibitors. The reported crystal structure of hTopoIIalpha-DNA complex (PDB ID: 4FM9) is not suitable for analyzing the merbarone-binding domain, because it is a biological assembly of hTopoIIalpha in C-gate open conformation. Therefore, 3D structure of hTopoIIalpha-DNA complex suitable for molecular modeling analysis at merbarone binding site was first generated. Using this generated complex, molecular docking analysis and molecular dynamics simulations were performed to explore the effect of merbarone on hTopoIIalpha-DNA complex. The binding energy for the enol form of merbarone with hTopoIIalpha-DNA was estimated to be -51.28 kcal/mol. The explored binding site and identified molecular recognition interactions were in accordance with the previously reported interference in the DNA-cleavage by merbarone. Virtual screening was performed using drug likeness filters, toxicity filters and ADMET descriptor based filters followed by molecular docking (ZINC database). Sixteen compounds were identified as merbarone-functional analogs suitable for hTopoIIalpha inhibition. These identified molecules can be considered for further evaluation of their anti-hTopoIIalpha activity. PMID- 30296752 TI - First principle study of electronic, mechanical, optical and thermoelectric properties of CsMO3 (M = Ta, Nb) compounds for optoelectronic devices. AB - The electronic, mechanical, optical and thermoelectric properties of Cesium based perovskites CsMO3 (M = Nb, Ta) in the cubic phase has been performed through PBEsol-mBJ scheme in the framework of DFT. The electronic band structures and density of states show the studied materials having a direct band gap in the visible range. The mechanical stability and ductile behavior have been analyzed from elastic constants. Moreover, the optical behavior of the studied materials has been analyzed in terms of dielectric functions, refractive index, extinction coefficient, absorption coefficient, optical conductivity, reflectivity and energy loss factor. Finally, the material response with temperature has been elaborated by electrical conductivity, thermal conductivity, Seebeck coefficient, power factor, heat capacity, Hall coefficient, susceptibility and electron density by using BoltzTraP code. This first principle calculation of optical and thermoelectric properties of the novel compounds provides a new route to the experimentalist for the potential application in energy renewable devices. PMID- 30296753 TI - Enhanced adsorption of oxytetracycline to weathered microplastic polystyrene: Kinetics, isotherms and influencing factors. AB - Microplastic polystyrene foam has been found widely in the environment and is readily transported by wind or water. Beached and virgin foams of size 0.45-1 mm were prepared as sorbents to study oxytetracycline sorption. Enhanced adsorption were found in the beached foams compared to the virgin foams, corresponding to the higher specific surface area, micropore area and the degree of oxidation of the former. The Freundlich Kf value was 894 +/- 84 ((mg kg-1) (mg L-1)1/n) for oxytetracycline adsorption on the beached foams, approximately twice as high as on the virgin foams. Effects of solution pH on adsorption to the beached foams were more pronounced to the virgin foams. Maximum adsorption occurred at pH 5 at which electrostatic repulsion between the microplastic surface and the oxytetracycline zwitterion was minimal, indicating that electrostatic interaction may have regulated adsorption. Moreover, H-bonding and multivalent cationic bridging mechanisms may also have affected the adsorption of oxytetracycline to the beached foams as reflected by the ionic effects. Adsorption was promoted more in the presence of humic acid than of fulvic acid, perhaps owing to pi-pi conjugation between the humic acid and the microplastic surface which led to enhanced electrostatic attraction for oxytetracycline. This study suggests that weathered polystyrene foams may act as carriers of antibiotics in the environment and their potential risks to ecosystem and human health merit further investigation. PMID- 30296754 TI - Endocrine disruption and chronic effects of plant protection products in bees: Can we better protect our pollinators? AB - Exposure to plant protection products (PPPs) is one of the causes for the population decline of pollinators. In addition to direct exposure, pollinators are exposed to PPPs by pollen, nectar and honey that often contain residues of multiple PPPs. While in legislation PPPs are regarded mainly for their acute toxicity in bees, other effects such as neurotoxicity, immunotoxicity, behavioural changes, stress responses and chronic effects that may harm different physiologically and ecologically relevant traits are much less or not regarded. Despite the fact that endocrine disruption by PPPs is among key effects weakening survival and thriving of populations, pollinators have been poorly investigated in this regard. Here we summarize known endocrine disruptive effects of PPPs in bees and compare them to other chronic effects. Endocrine disruption in honey bees comprise negative effects on reproductive success of queens and drones and behavioural transition of nurse bees to foragers. Among identified PPPs are insecticides, including neonicotinoids, fipronil, chlorantraniliprole and azadirachtin. So far, there exists no OECD guideline to investigate possible endocrine effects of PPPs. Admittedly, investigation of effects on reproduction success of queens and drones is rarely possible under laboratory conditions. But the behavioural transition of nurse bees to foragers could be a possible endpoint to analyse endocrine effects of PPPs under laboratory conditions. We identified some genes, including vitellogenin, which regulate this transition and which may be used as biomarkers for endocrine disruptive PPPs. We plea for a better implementation of the adverse outcome pathway concept into bee's research and propose a procedure for extending and complementing current assessments, including OECD guidelines, with additional physiological and molecular endpoints. Consequently, assessing potential endocrine disruption in pollinators should receive much more relevance. PMID- 30296755 TI - Managing nutrients to mitigate soil pollution. AB - The health of soils is key not only to agricultural productivity, but to all the ecosystem services provided in terms of maintaining the quality of water, air, and food. Nutrient inputs to agricultural soils produce large benefits to human health, including the provisioning of calories and protein supporting at least half the human population, enhancing micronutrient bioavailability in food, improving crop quality, and strengthening tolerance to plant disease. With appropriate nutrient stewardship, such inputs contribute to soil health and prevent soil degradation. When mismanaged and applied inappropriately, either mineral or organic sources of nutrients can become pollutants both in soils and in water and air. The solution being embraced by industry and governments around the world is the implementation of principles of 4R Nutrient Stewardship, ensuring that the right source of nutrient is applied at the right time, in the right place and at the right rate. PMID- 30296756 TI - Salt marsh denitrification is impacted by oiling intensity six years after the Deepwater Horizon oil spill. AB - Coastal salt marshes provide the valuable ecosystem service of removing anthropogenic nitrogen (N) via microbially-mediated denitrification. During the 2010 Deepwater Horizon (DWH) spill, oil exposure killed marsh plants in some regions and contributed to rapid compositional shifts in sediment microbial communities, which can impact ecosystem denitrification capacity. Within 3-5 years of the spill, plant biomass and microbial communities in some impacted marshes can recover to a new stable state. The objective of this study was to determine whether marsh recovery 6 years after the DWH oil spill results in subsequent recovery of denitrification capacity. We measured denitrification capacity (isotope pairing technique), microbial 16S rRNA gene composition, and denitrifier abundance (quantitative PCR) at sites subjected to light, moderate, and heavy oiling during the spill that were not targeted by any clean-up efforts. There were no differences in plant belowground biomass, sediment extractable NH4+, inorganic nitrogen flux, 16S rRNA composition, 16S rRNA diversity, or denitrifier functional gene (nirS, norB, and nosZ) abundances associated with oiling status, indicating that certain drivers of ecosystem denitrification capacity have recovered or achieved a new stable state six years after the spill. However, on average, denitrification capacities at the moderately and heavily oiled sites were less than 49% of that of the lightly oiled site (27.7 +/- 14.7 and 37.2 +/- 24.5 vs 71.8 +/- 33.8 MUmol N m-2 h-1, respectively). The presence of heavily weathered oiled residue (matched and non-matched for MC252) had no effect on process rates or microbial composition. The loss of function at the moderately and heavily oiled sites compared to the lightly oiled site despite the comparable microbial and environmental factors suggests that oiling intensity plays a role in the long-term recovery of marsh ecosystem services.

PMID- 30296758 TI - Key coastal landscape structures for resilient coastal green infrastructure to enhance the abundance of migratory birds on the Yellow Sea. AB - The aim of this study was to investigate the key landscape structures of migratory bird habitats that affect abundance of migratory birds to promote resilient coastal green infrastructure planning on the Yellow Sea coast. We classified coastal areas into four watersheds of South Korea and conducted multivariate regression analysis between migratory bird populations and landscape structures including total class area (CA), patch area distribution (MN), patch density (PD), and edge density (ED). At the national level, sandbank MN, sandbank CA, water ED, and grasslands were derived as key landscape structures affecting the abundance of migratory birds. At the watershed level, key landscape structures were determined as follows: Urban area_MN for the Han River watershed, rice paddy MN for the Asan watershed, rice paddy CA for Saemangeum, and grassland MN for the Youngsan River watershed. Considering the multifunctionality, redundancy, and connectivity of the resilience strategy, we provide specific coastal infrastructure planning recommendations at the national and watershed scales. PMID- 30296760 TI - Characterization of Cr (VI) - Containing solid phase particles in dry dust deposition in Daejeon, South Korea. AB - Solid phase speciation of chromium in dry dust deposition and road paint was determined using transmission electron microscopy (TEM) and X-ray absorption spectroscopy (XAS). Spherical black carbon aggregates in dry dust deposition contained discrete nano-sized lead chromate (PbCrO4) and zinc chromate (ZnCrO4), which likely originated from yellow traffic paint and zinc chromate primer (corrosion resistant pigment), respectively based on their main applications. Road marking paint samples from auto roads included lead chromate particles whose size, shape, composition and crystal structure were similar to those in dry dust deposition. A slight difference was found at the particle boundary. Namely, lead chromate in traffic paint was encapsulated by silica-bearing matrix, while discrete lead chromate in the black carbon of dry deposition was rarely enclosed within silica-bearing matrix. The Cr K edge X-ray absorption near edge structure (XANES) spectrum for dry deposition showed the characteristic pre-edge resonance peak similar to the spectra for the Cr(VI) standard and road paint, but the lower intensity. The amount of Cr(VI) accounted for approximately 45% of the total Cr in the dust sample. The solid phase speciation of Cr observed using TEM and their valence states determined using XANES were consistent with the chemical speciation determined using the sequential extraction. The contribution of this study is that XANES was applied to identify Cr valance states in urban dust deposition and zinc chromate was found as a Cr(VI) phase in dry dust deposition using TEM. These study results provide novel data on Cr speciation and Cr(VI) containing mineral phases in dry dust deposition and their potential sources. Based on the wide use of lead and zinc chromate, atmospheric contamination with these solid phase speciation of Cr(VI) is expected in other cities in the world. PMID- 30296759 TI - Concentrations of perfluoroalkyl substances and bisphenol A in newborn dried blood spots and the association with child behavior. AB - Experimental studies suggest that prenatal exposure to endocrine disrupting chemicals interferes with developmental processes in the fetal brain. Yet, epidemiological evidence is inconclusive. In a birth cohort (2008-2010, upstate New York), we quantified concentrations of perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), and bisphenol A (BPA) in stored newborn dried blood spots using liquid chromatography/tandem mass spectrometry. Mothers reported on children's behavior using the Strengths and Difficulties Questionnaire at age 7 (650 singletons and 138 twins). Difficulties in total behavior (i.e., emotional, conduct, hyperactivity, and peer problems) and prosocial behavior were classified using validated cut-offs. We used logistic regression with generalized estimating equations to estimate the odds of having difficulties per exposure category. In total, 111 children (12.1%) had total behavioral difficulties and 60 (6.5%) had difficulties in prosocial behavior. The median (interquartile range) of PFOS, PFOA, and BPA were 1.74 ng/ml (1.33), 1.12 ng/ml (0.96), and 7.93 ng/ml (10.79), respectively. Higher PFOS levels were associated with increased odds of having behavioral difficulties (OR per SD of log PFOS = 1.30, 95%CI: 1.03-1.65). We observed associations between PFOS in the highest relative to the lowest quartile and behavioral difficulties (OR for PFOS1.14-1.74 = 1.65, 95%CI: 0.84-3.34; PFOS1.75-2.47 = 1.73, 95%CI: 0.87-3.43; and PFOS>2.47 = 2.47, 95%CI: 1.29-4.72 compared to PFOS<1.41). The associations between higher concentrations of PFOS and behavioral difficulties at age 7 years were driven by problems in conduct and emotional symptoms. Higher PFOA levels were associated with difficulties in prosocial behavior (OR = 1.35, 95%CI: 1.03 1.75). There was an inverse association between BPA concentrations and difficulties in prosocial behavior but only in the 2nd and 4th quartiles. We found no interactions between sex and chemical concentrations. Increasing prenatal exposure to PFOS and PFOA, as reflected in neonatal concentrations, may pose risk for child behavioral difficulties.

AB - This study aimed to better understand in situ cumulative effects of anthropogenic stressors on the health of St. Lawrence River (QC, Canada) yellow perch populations using high-throughput transcriptomics and a multi-biological level approach. Fish were collected in the upstream fluvial Lake Saint-Francois (LSF) with low degree of environmental perturbations; Lake Saint-Louis (LSL) considered having a moderate degree of anthropogenic stressors, and Lake Saint-Pierre (LSP) a sector where the perch population has been severely declining. Morphometric results indicated that fish from the downstream LSP showed lower body condition compared to LSF and LSL. Liver transcriptomic responses were assessed by RNA sequencing. Two hundred and eighty genes were over-transcribed in LSP perch while 200 genes were under-transcribed compared to LSF and LSL. In LSP fish, genes transcripts related to reproduction, retinol, iron, thyroid hormones, oxidative stress, lipid metabolism and immune functions were among the most abundant suggesting that multiple metabolic and physiological pathways were impacted by environmental stressors at this site. Inhibition of liver superoxide dismutase, catalase and glutathione S-transferase activities were also observed at the cellular level. Overall, identified impacted biological pathways in perch from LSP may help understand the precarious state of this population and identify the factors inhibiting its recovery. PMID- 30296763 TI - Dual impact of dissolved organic matter on cytotoxicity of PVP-Ag NPs to Escherichia coli: Mitigation and intensification. AB - Cytotoxicity of silver nanoparticles (Ag NPs) is attributed to silver internalization, which can be depressed by dissolved organic matter (DOM) to form Ag-DOM. Ag-DOM are bioavailable and then silver internalization could be increased. Herein, 3 and 48-h Escherichia coli viability bioassays were employed to evaluate effect of fulvic acid and humic acid (10 mg L-1) on cytotoxicity of 30 and 100 nm PVP-Ag NPs. Moreover, zebrafish embryos were used as reference model to understand silver internalization routes. Ag ions or Ag-DOM internalization varied in routes to Escherichia coli and zebrafish embryos. Cytotoxicity mechanisms of PVP-Ag NPs are dynamic. In 3-h bioassays, cytotoxicity of PVP-Ag NPs mainly involves Ag particle-related toxicity. DOM significantly mitigated cytotoxicity of PVP-Ag NPs (p < 0.05) through adhering on surface of PVP-Ag NPs. Ag ions or Ag-DOM were hardly internalized into Escherichia coli cells during 3-h exposures duration. In 48-h bioassays, cytotoxicity of PVP-Ag NPs is dependent on Ag ion-related and particle-related toxicity. Silver was internalized into Escherichia coli via Ag-DOM consumption as an indirect route. Thus, DOM promoted silver internalization into Escherichia coli but not into zebrafish embryos, significantly intensifying cytotoxicity (p < 0.05). The results suggested DOM has a dual impact on cytotoxicity of PVP-Ag NPs: mitigation and intensification. For risk assessment, it should be considered that cytotoxicity mechanisms of PVP-Ag NPs are dynamic and threats can be intensified by DOM during prolonged exposure. PMID- 30296764 TI - Pre-ozonation of source water: Assessment of efficacy against Giardia duodenalis cysts and effects on natural organic matter. AB - The protozoan Giardia duodenalis is one of the parasites of primary concern in drinking water treatment plants, due to its resistance to chlorination. Another matter of concern regarding chlorination of drinking water is the formation of disinfection by-products in the presence of precursors such as natural organic matter (NOM). In this study, the effects of ozonation (5 mg L-1) on G. duodenalis cysts in raw surface water from a drinking water treatment plant were evaluated, and the presence and alteration of NOM were assessed, as an indicative of the potential to prevent total organic halogen (TOX) formation during post chlorination. Following ozone treatment, the presence of damaged cysts was observed by direct immunofluorescence assay (IFA) and confirmed by the molecular approach propidium monoazide-polymerase chain reaction (PMA-PCR). Using an animal model, analysis of the intestinal tissues revealed that 80% of the animals inoculated with ozonated water were positive for trophozoites. This study shows that analysis of intestinal fragments is imperative to accurately assess animal infection following inoculation of treated cysts. More importantly, considering the low infective dose of Giardia cysts in susceptible hosts, an ozone dosage usually applied in drinking water treatment plants did not completely inactivate G. duodenalis cysts in surface water. Nonetheless, the results suggest that competitive reactions with NOM have occurred, and the applied ozone dosage has proven useful to remove NOM reactivity, and thus prevent halogenated DBP formation during post-chlorination. PMID- 30296765 TI - Metabolomics reveals defensive mechanisms adapted by maize on exposure to high molecular weight polycyclic aromatic hydrocarbons. AB - Polycyclic aromatic hydrocarbons are an important group of persistent organic pollutants. Using plants to remediate PAHs has been recognized as a cost effective and environmentally friendly technique. However, the overall impact of PAHs on the regulation of plant metabolism has not yet been explored. In this study, we analyzed the alteration in the maize (Zea mays L.) metabolome on exposure to high molecular weight PAHs such as benzo[a]pyrene (BaP) and pyrene (PYR) in a hydroponic medium, individually and as a mixture (BaP + PYR) using GC MS. The differences in the metabolites were analyzed using XCMS (an acronym for various forms (X) of chromatography-mass spectrometry), an online-based data analysis tool. A significant variation in metabolites was observed between treatment groups and the unspiked control group. The univariate, multivariate and pathway impact analysis showed there were more significant alterations in metabolic profiles between individual PAHs and the mixture of BaP and PYR. The marked changes in the metabolites of galactose metabolism and aminoacyl tRNA biosynthesis in PAHs treated maize leaves exhibit the adaptive defensive mechanisms for individual and PAHs mixture. Therefore, the metabolomics approach is essential for an understanding of the complex biochemical responses of plants to PAHs contaminants. This knowledge will shed new light in the field of phytoremediation, bio-monitoring, and environmental risk assessment. PMID- 30296766 TI - A density functional theory study of the molecular interactions between a series of amides and sulfuric acid. AB - Amides, a class of nitrogen-containing organic pollutants in the atmosphere, may affect the formation of atmospheric aerosols by the interactions with sulfuric acid. Here, the molecular interactions of sulfuric acid with formamide, methylformamide, dimethylformamide, acetamide, methylacetamide and dimethylacetamide was investigated by density functional theory. Geometry optimization and Gibbs free energy calculation were carried out at M06-2X/6 311++G(3df,3pd) level. The results indicate that the addition of amides to H2SO4 might have a promoting effect on atmospheric new particle formation at 298.15 K and 1 atm. In the initial stage of new particle formation, the binding capacity of amides and sulfuric acid is stronger than ammonia, but weaker than methylamine. It is worth noting that the trans-methylacetamide could have similar capabilities of stabilizing sulfuric acid as dimethylamine. In the presence of water, amides are found to only have a weak enhancement capability on new particle formation. In addition, we can infer from evaporation rate that the small molecule clusters of formamide and sulfuric acid may be more energetically favorable than macromolecule clusters.

Computer-aided sperm analysis (CASA) can be used for kinematic analysis of spermatozoa, which provides additional insights into sperm motion characteristics. OBJECTIVE: To explore the associations of urinary and seminal plasma metal/metalloid concentrations with CASA motion parameters and assess the degree of correspondence between the two sample types. METHODS: Eighteen metals/metalloids in seminal plasma and repeated urine samples were determined among 746 men recruited from a reproductive center. We assessed their associations with 6 CASA motion parameters [i.e., straight-line velocity (VSL), curvilinear velocity (VCL), average path velocity (VAP), linearity (LIN), straightness (STR) and amplitude head displacement (ALH)] using multivariable linear regression models. RESULTS: We found significantly inverse dose-dependent relationships between seminal plasma arsenic (As) and VSL, VCL and VAP, between seminal plasma selenium (Se) and VSL and VAP, between seminal plasma zinc (Zn) and STR and LIN, and between seminal plasma manganese (Mn) and LIN in single metal models [all false discovery rate (FDR) adjusted P for trend < 0.05]. These dose-response relationships remained statistically significant based on multiple metal models and restricted cubic spline functions. Metal/metalloid concentrations in urine poorly predicted the same-day seminal plasma concentrations [coefficient of determination (R2) < 0.15]. We didn't find any significant associations between urinary metal/metalloid concentrations and the CASA motion parameters. CONCLUSION: Exposure to high levels of As, Se, Mn and Zn may impair sperm motion capacity. Concentrations of metals/metalloids in spot urine samples cannot accurately predict same-day seminal plasma exposure levels.

AB - Transformation products (TPs) can be formed from organic micropollutants in the water cycle through both biological and technological processes. Despite the TPs' potentially altered toxicity compared to their parent compounds, transformation processes are not routinely monitored, and in particular those induced by drinking water treatment remain elusive. This lack of information is mainly due to the technical challenges in analyzing TPs, which are often unknown compounds occurring in low concentrations. Their analysis requires sophisticated analytical techniques such as non-target screening (NTS) based on high-resolution tandem mass spectrometry (HRMS/MS) methods combined with novel data analysis approaches. Here, we addressed the challenges of TP analysis and the scarcity of TP research concerning studies in drinking water. We performed lab-scale experiments to monitor TP formation of three organic micropollutants prevalent in drinking water sources, i.e. carbamazepine, clofibric acid and metolachlor, during rapid sand filtration and ozonation, two readily applied biotic and abiotic drinking water treatments, respectively. To facilitate TP identification in the NTS data, halogenated and/or isotopically labeled parent compounds were used, revealing potential TPs through their isotopic patterns. The experimental results showed that degradation of the parent compounds and TP formation were treatment and compound specific. In silico TP prediction and literature mining enabled suspect screening of the non-target data and thereby significantly enhanced TP identification. Overall, the developed workflow enables an efficient and more comprehensive assessment of drinking water quality changes during water treatment. PMID- 30296769 TI - Monetized health benefits attributable to mobile source emission reductions across the United States in 2025. AB - By-products of mobile source combustion processes, such as those associated with gasoline- and diesel-powered engines, include direct emissions of particulate matter as well as precursors to particulate matter and ground-level ozone. Human exposure to fine particulate matter with an aerodynamic diameter smaller than 2.5 MUm (PM2.5) is associated with increased incidence of premature mortality and morbidity outcomes. This study builds upon recent, detailed source-apportionment air quality modeling to project the health-related benefits of reducing PM2.5 from mobile sources across the contiguous U.S. in 2025. Updating a previously published benefits analysis approach, we develop national-level benefit per ton estimates for directly emitted PM2.5, SO2/pSO4, and NOX for 16 mobile source sectors spanning onroad vehicles, nonroad engines and equipment, trains, marine vessels, and aircraft. These benefit per ton estimates provide a reduced-form tool for estimating and comparing benefits across multiple mobile source emission scenarios and can be applied to assess the benefits of mobile source policies designed to improve air quality. We found the benefit per ton of directly emitted PM2.5 in 2025 ranges from $110,000 for nonroad agriculture sources to $700,000 for onroad light duty gas cars and motorcycles (in 2015 dollars and based on an estimate of PM-related mortality derived from the American Cancer Society cohort study). Benefit per ton values for SO2/pSO4 range from $52,000 for aircraft sources (including emissions from ground support vehicles) to $300,000 for onroad light duty diesel emissions. Benefit per ton values for NOX range from $2100 for C1 and C2 marine vessels to $7500 for "nonroad all other" mobile sources, including industrial, logging, and oil field sources. Benefit per ton estimates increase approximately 2.26-fold when using an alternative concentration response function to derive PM2.5-related mortality. We also report benefit per ton values for the eastern and western U.S. to account for broad spatial heterogeneity patterns in emissions reductions, population exposure and air quality benefits.

AB - River impoundment by the construction of dams potentially modifies a wide range of abiotic and biotic factors in lotic ecosystems and is considered one of the most significant anthropogenic impacts on rivers globally. The past two decades have witnessed a growing body of research centred on quantifying the effects of river impoundment, with a focus on mitigating and managing the effects of individual large dams. This study presents a novel multi-scale comparison of paired downstream and control sites associated with multiple water supply reservoirs (n = 80) using a spatially extensive multi-year dataset. Macroinvertebrate community structure and indices were analysed in direct association with spatial (e.g. region) and temporal variables (e.g. season) to identify consistent patterns in ecological responses to impoundment. Macroinvertebrate communities at monitoring sites downstream of water supply reservoirs differed significantly from those at control sites at larger spatial scales, both in terms of community structure and taxa richness. The effect was most significant at the regional scale, while biogeographical factors appeared to be important drivers of community differences at the national scale. Water supply reservoirs dampened natural seasonal patterns in community structure at sites downstream of impoundments. Generally, taxonomic richness was higher and %EPT richness lower at downstream sites. Biomonitoring indices used for river management purposes were able to detect community differences, demonstrating their sensitivity to river regulation activities. The results presented improve our understanding of the spatially extensive and long-term effects of water supply reservoirs on instream communities and provide a basis for the future implementation of mitigation measures on impounded rivers and heavily modified waterbodies. PMID- 30296771 TI - Ambient air pollution and fetal growth restriction: Physician diagnosis of fetal growth restriction versus population-based small-for-gestational age. AB - BACKGROUND: Ambient air pollution may affect fetal growth restriction (FGR) through several mechanisms. However, prior studies of air pollution and small-for gestational age (SGA), a common proxy for FGR, have reported inconsistent findings. OBJECTIVE: We assessed air pollution in relation to physician-diagnosed FGR and population-based SGA in the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Consecutive Pregnancy Study (2002 2010). METHODS: Among 50,005 women (112,203 singleton births), FGR was captured from medical records and ICD-9 codes, and SGA determined by population standards for birthweight <10th, <5th and <3rd percentile. Community Multiscale Air Quality models estimated ambient levels of seven criteria pollutants for whole pregnancy, 3-months preconception, and 1st, 2nd and 3rd trimesters. Generalized estimating equations with robust standard errors accounted for interdependency of pregnancies within participant. Models adjusted for maternal age, race/ethnicity, pre-pregnancy body mass index, smoking, alcohol, parity, insurance, marital status, asthma and temperature. RESULTS: FGR was diagnosed in 1.5% of infants, and 6.7% were <10th, 2.7% <5th and 1.5% <3rd percentile for SGA. Positive associations of SO2, NO2 and PM10 and negative associations of O3 with FGR were observed throughout preconception and pregnancy. For example, an interquartile increase in whole pregnancy SO2 was associated with 16% (95% CI 8%, 25%) increased FGR risk, 17% for NO2 (95% CI 9%, 26%) and 12% for PM10 (95% CI 6%, 19%). Associations with SGA were less clear. CONCLUSIONS: Chronic exposure to air pollution may be associated with FGR but not SGA in this low-risk population.

AB - Vegetation restoration was implemented to control soil erosion in the karst regions of southwest China. It is essential to assess the soil function and quality scientifically during this process and to adopt suitable management practices for this area. However, few studies have been conducted to comprehensively evaluate the effect of vegetation restoration on soil quality in this severely eroded karst area. By taking 302 soil samples from 11 vegetation types, this study investigated the influence of different types of vegetation restoration on soil quality using an integrated soil quality index (SQI) and a generalized linear model (GLM). Vegetation types had significant effects on soil properties and thus on soil quality. SQI was developed by using TN, TP, TK, AP, and clay content; TN had highest weighting values (0.58), which indicated that it contributed the most to final SQI. The highest and lowest SQI values were observed for primary forest and cropland, respectively. Overall, vegetation restoration (e.g., natural restoration, artificial forests and artificial grassland) improved soil quality significantly. A GLM model explained 73.20% of the total variation in SQI, and vegetation type explained the largest proportion (46.39%) of the variation, which implies that the vegetation restoration practices can greatly enhance the soil quality in karst landscapes of southwest China. The results of this study may be used to improve implication of ecological restoration and management in degraded regions. PMID- 30296774 TI - Response of plant production to growing/non-growing season asymmetric warming in an alpine meadow of the Northern Tibetan Plateau. AB - A field growing/non-growing season asymmetric warming experiment (C: control, i.e., no warming in the entire year; GLNG: growing season warming lower than non growing season warming; GHNG: growing season warming higher than non-growing season warming) was conducted in an alpine meadow of the Northern Tibetan Plateau in early June 2015. The effects of growing/non-growing season asymmetric warming on the normalized difference vegetation index (NDVI), soil adjusted vegetation index (SAVI), aboveground biomass (AGB) and gross primary production (GPP) in 2015-2017 were examined. The 'GLNG' and 'GHNG' treatments significantly increased the annual mean air temperature (Ta) by 2.95 degrees C and 2.76 degrees C, and the vapor pressure deficit (VPD) by 0.23 kPa and 0.28 kPa but significantly reduced the annual mean soil moisture (SM) by 0.02 m3 m-3 and 0.02 m3 m-3 respectively; however, changes in the annual mean Ta, VPD and SM were the same between the 'GLNG' and 'GHNG' treatments over the three years in 2015-2017. There were no significant differences in the SAVI and GPP among the 'C', 'GLNG' and 'GHNG' treatments over the three growing seasons in 2015-2017. The 'GLNG' and 'GHNG' treatments did not significantly affect the NDVI and AGB compared to 'C', whereas the NDVI and AGB under the 'GLNG' treatment were significantly greater than those under the 'GHNG' treatment over the three growing seasons in 2015 2017. The significant differences in NDVI and AGB between the 'GLNG' and 'GHNG' treatments may be attributed to the different effects under the 'GLNG' and 'GHNG' treatments on the non-growing season Ta, growing season water availability and soil nitrogen availability. Therefore, the non-growing season with a higher warming magnitude may have stronger effects on the aboveground plant production than did the growing season with a higher warming magnitude in the alpine meadow of the Northern Tibetan Plateau. PMID- 30296775 TI - Impacts of climate change on streamflow and sediment concentration under RCP 4.5 and 8.5: A case study in Purna river basin, India. AB - Climate change has a significant effect on various hydrological processes in a large river basin. The assessment of these processes is also useful for water resource management and long-term sustainability of any hydrological project. In this study, an attempt is made to quantify the effects of climate change on streamflow and sediment concentration in the Purna river basin, India. Three Regional Circulation Models (RCMs) with two Representative Concentration Pathways (RCPs) 4.5 and 8.5 for the four future periods of P1 (2009-2031), P2 (2032-2053), P3 (2054-2075) and P4 (2076-2099) are considered. Differences in scenarios are compared with the base period 1980-2005. The SWAT is used on monthly basis for the period 1980 to 2005 with calibration period 1980 to 1994 and validation period 1995 to 2005. The projected precipitation and temperature show a significant increasing trend compared to the baseline condition for both RCPs. Similarly, the average monthly streamflow is projected to increase by 24.47 to 115.94m3/s whereas average monthly sediment concentration by 32.58 to 162.96mg/l under RCP 4.5 and 8.5. In particular, streamflow and sediment are expected to increase significantly from June to September at the outlet of the basin. The study results give insight into future hydrological scenarios which will be useful for policy makers to implement effective water resource strategies. PMID- 30296776 TI - Protein-specific distribution patterns of perfluoroalkyl acids in egg yolk and albumen samples around a fluorochemical facility. AB - In this study, eggs from free-range and barn chickens in farms around a fluorochemical facility were collected to assess the distribution profiles of perfluoroalkyl acids (PFAAs), including isomers of perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), and perfluorohexane sulfonate (PFHxS), in egg yolk and albumen. The results revealed that the concentrations of PFAAs in yolks were significantly higher than those in albumen. All 17 PFAAs examined could be detected in yolks, showing decreasing concentrations with increasing distance from the fluorochemical facility. The three predominant compounds in yolks were perfluorobutanoic acid (PFBA, mean concentration 81.4 ng/g ww), PFOS (28.0 ng/g ww), and PFOA (4.83 ng/g ww), and this result is consistent with the product structure of the facility. Moreover, n-PFOA, n-PFOS, and n-PFHxS were the dominant contaminants in yolk, with mean concentrations of 4.75, 25.7, and 4.29 ng/g ww, respectively. In albumen, PFBA was still the predominant PFAA congener (mean concentration = 3.93 ng/g ww), followed by PFOA. Docking analysis indicated that the PFAAs presented higher binding abilities with the low density lipoprotein, high density lipoprotein, and vitellin proteins in yolk than that with ovalbumin albumen proteins, which might be the main factor influencing the possible difference in distributions of PFAAs in yolk and albumen. PMID- 30296777 TI - Diversification of forest management regimes secures tree microhabitats and bird abundance under climate change. AB - The loss of biodiversity in temperate forests due to combined effect of climate change and forest management poses a major threat to the functioning of these ecosystems in the future. Climate change is expected to modify ecological processes and amplify disturbances, compromising the provisioning of multiple ecosystem services. Here we investigate the impacts of climate change and forest management on the abundance of tree microhabitats and forest birds as biodiversity proxies, using an integrated modelling approach. To perform our analysis, we calibrated tree microhabitat and bird abundance in a forest landscape in Southwestern Germany, and coupled them with a climate sensitive forest growth model. Our results show generally positive impacts of climate warming and higher harvesting intensity on bird abundance, with up to 30% increase. Conversely, climate change and wood removals above 5% of the standing volume led to a loss of tree microhabitats. A diversified set of management regimes with different harvesting intensities applied in a landscape scale was required to balance this trade-off. For example, to maximize the expected bird abundance (up to 11%) and to avoid tree microhabitat abundance loss of >20% necessitates setting aside 10.2% of the forest area aside and application of harvesting intensities < 10.4% of the standing volume. We conclude that promoting forest structural complexity by diversifying management regimes across the landscape will be key to maintain forest biodiversity in temperate forests under climate change. PMID- 30296778 TI - Assessing pH-dependent toxicity of fluoxetine in embryonic zebrafish using mass spectrometry-based metabolomics. AB - While it is well known that fluoxetine is more toxic to aquatic organisms at high pH, the metabolic dysregulations related to observed pH-dependent effects are still poorly understood. In the present study, we utilized a gas chromatography mass spectrometry (GC-MS) based metabolomics approach to assess metabolomic profile changes in developing zebrafish embryos following exposure (2 hpf-96 hpf) to different concentrations of fluoxetine at three environmentally relevant pH values (7.0, 8.0, and 9.0). Multivariate data analyses and pathway analyses were used to assess metabolomic profile changes and elicit important biochemical information regarding pH-dependent toxicity of fluoxetine. Overall, the affected biochemical functions related to fluoxetine exposure included amino acid metabolism, energy metabolism, nitrogenous waste excretion and osmolyte functions. While fluoxetine exposure (56 MUg/L, 70 MUg/L and 500 MUg/L) caused no significant changes at pH 7, 500 MUg/L and 70 MUg/L fluoxetine was differentiated from the controls at pH 8 and pH 9 respectively. Three, eight and seven metabolites were identified as the most adversely affected at pH 7, 8 and 9, respectively. The altered metabolites associated with fluoxetine toxicity at high pH included urea, glycine and d-glucose 6-phosphate. Exposure to 70 MUg/L fluoxetine, did not cause significant metabolomic profile changes at pH 7, However, the results indicate that this exposure concentration at pH and 9 can cause significant metabolic dysregulation related to apoptosis and oxidative stress. Increasing aqueous pH progressively enhanced fluoxetine induced toxicity for the 70 MUg/L exposure group. The observed impacts included higher energy consumption at pH 7, a breakdown of reserve energy to supplement energy demand at pH 8 and impaired lipid metabolism at pH 9. This study provides important information regarding molecular-level effects related to pH-dependent exposure of fluoxetine in embryonic zebrafish. PMID- 30296779 TI - Efficient GPU-based Monte-Carlo simulation of diffusion in real astrocytes reconstructed from confocal microscopy. AB - The primary goal of this work is to develop an efficient Monte-Carlo simulation of diffusion-weighted signal in complex cellular structures, such as astrocytes, directly derived from confocal microscopy. In this study, we first use an octree structure for spatial decomposition of surface meshes. Octree structure and radius-search algorithm help to quickly identify the faces that particles can possibly encounter during the next time step, thus speeding up the Monte-Carlo simulation. Furthermore, we propose to use a three-dimensional binary marker to describe the complex cellular structure and optimize the particle trajectory simulation. Finally, a GPU-based version of these two approaches is implemented for more efficient modeling. It is shown that the GPU-based binary marker approach yields unparalleled performance, opening up new possibilities to better understand intracellular diffusion, validate diffusion models, and create dictionaries of intracellular diffusion signatures. PMID- 30296780 TI - Calculating Standard Kt/V during Hemodialysis Based on Urea Mass Removed. AB - BACKGROUND/AIMS: We derived a novel equation for calculating weekly urea standard Kt/V (stdKt/V) during hemodialysis (HD) based on urea mass removed, comparable to the approach during peritoneal dialysis. METHODS: Theoretical consideration of urea mass balance during HD led to the following equation for stdKt/V, namely, stdKt/V = N * (URR + UFV/V), where N is the number of treatments per week, URR is urea reduction ratio per treatment, UFV is ultrafiltration volume per treatment, and V is postdialysis urea distribution volume. URR required corrections for postdialysis rebound and intradialytic urea generation. We compared the accuracy of this approach with previous equations for stdKt/V by numerical simulations using a 2-compartment model of urea kinetics for thrice-weekly and more frequent HD prescriptions. RESULTS: The proposed equation based on urea mass removed predicted values of stdKt/V that are equivalent to those calculated by previous equations for stdKt/V. CONCLUSION: This work provides a novel approach for calculating stdKt/V during HD and strengthens the theoretical understanding of stdKt/V. PMID- 30296781 TI - A Rare Case of Concomitant Deletions in 15q11.2 and 19p13.3. AB - A female individual with concomitant deletions in 15q11.2 and 19p13.3 is reported. She presents facial dysmorphisms, motor delay, learning difficulties, and mild behavioral impairment. After chromosomal microarray analysis, the final karyotype was established as 46,XX.arr[GRCh37] 15q11.2 (22770421_23282798)*1,19p13.3(3793904_4816330)*1. The deletion in 15q11.2 is 507 kb in size involving 7 non-imprinted genes, 4 of which are registered in the OMIM database and are implicated in neuropsychiatric or neurodevelopmental disorders. The deletion in 19p13.3 is 1,022 kb in size and encompasses 47 genes, most of which do not have a well-known function. The genotype-phenotype correlation is discussed, and most of the features could be related to the 19p13.3 deletion, except for velopharyngeal insufficiency. Other genes encompassed in the deleted region, as well as unrecognized epistatic factors could also be involved. Nevertheless, the two-hit model related to the 15q11.2 deletion would be an important hypothesis to be considered. PMID- 30296782 TI - The Anticancer Effect of Huaier Extract in Renal Cancer 786-O Cells. AB - BACKGROUND: Trametes robiniophila Murr (Huaier) has been used as an adjuvant therapy of tumor in traditional Chinese medicine for many years, but the underlying mechanisms are largely unknown. In the present study, we tested the inhibitory effect of Huaier extract on renal cancer 786-O cells and explored the possible mechanisms. METHODS: 786-O cells were treated by gradient concentrations of Huaier extract, cell viability, invasion, migration and apoptosis were assessed by cell counting kit 8, cell scratch, transwell, and flow cytometry assay in vitro. The changes in protein level were detected by western blot analysis. Finally, the anticancer effect of Huaier was tested in vivo by nude mouse tumorigenicity assay. RESULTS: Viability of 786-O cells was suppressed by Huaier in a time- and dose-dependent manner; cell invasion and migration were also dramatically inhibited. Flow cytometry assays showed that Huaier could induce cell apoptosis. Western blotting analysis indicated that Huaier suppressed the activation of PI3K/AKT/mTOR/p70S6K/4E-BP1 signaling pathway. We also found that Huaier could partly reverse the epithelialmesenchymal transition (EMT) process. In vivo experiment indicated that tumor growth in the xenograft mouse model was suppressed by Huaier. CONCLUSION: Huaier plays an anticancer effect partially through the suppression of the PI3K/AKT/mTOR/p70S6K/4E-BP1 pathway and by reversing the EMT process. Huaier may act as an effective agent for treating renal cell carcinoma. PMID- 30296783 TI - Meiotic Recombination Differences in Rams from Three Breeds of Sheep in the US. AB - Meiotic recombination is an important contributor to genetic variation and ensures proper chromosome segregation during gametogenesis. Previous studies suggest that at least 1 crossover (CO) per chromosome arm is important to avoid mis-segregation. While the total number of COs per spermatocyte is known to differ in mice, this is only beginning to be evaluated in sheep. This study used a cytogenetic approach to quantify and compare the number of COs per spermatocyte in rams from 3 breeds of sheep: Suffolk, Icelandic, and Targhee. In total, 2,758 spermatocytes and over 170,000 COs were examined. Suffolk rams exhibited the lowest mean number of COs (61.1 +/- 0.15) compared to Icelandic (63.5 +/- 0.27) and Targhee (65.9 +/- 0.26) rams. Significant differences in the number of COs per spermatocyte were observed between Suffolk, Icelandic, and Targhee breeds as well as within each breed. Additionally, the number and location of COs were characterized for homologous chromosomes in a subset of spermatocytes for each ram. A positive correlation was identified between the number of COs and the length of the homologous chromosome pair. Suffolk and Icelandic rams exhibited up to 7 COs per chromosome, while Targhee rams exhibited up to 9. Further, distinct CO location preferences on homologous chromosome pairs with 1, 2, 3, and 4 COs were observed in all 3 breeds. These data in sheep will aid in elucidating the mechanism of mammalian meiotic recombination, an important contributor to genetic diversity. PMID- 30296784 TI - The Relationship between Maxillary Sinus Lateral Wall Thickness, Alveolar Bone Loss, and Demographic Variables: A Cross-sectional Cone Beam Computerized Tomography Study. AB - OBJECTIVES: Sinus floor evelation and augmentation surgery is widely used as a reliable procedure to increase insufficient bone height in the posterior maxillary area. The purpose of the present clinical study was to determine the associations between periodontal bone loss (PBL), maxillary sinus lateral bone wall thickness, age, and gender using cone beam computerized tomography (CBCT). MATERIAL AND METHOD: The current retrospective study consists of 716 maxillary sinus CBCT images of 358 patients. The CBCT scans were assessed to detect the relationship between lateral wall thickness and PBL. ANOVA and student t test analysis were used to determine the influence of PBL on sinus lateral wall thickness. RESULTS: Sinus lateral wall thickness was significantly associated with PBL (p < 0.05) at 3 mm, 13 mm and 15 mm height. There was no significant association between lateral wall thickness and gender (p > 0.05). However, there was a significant association between lateral wall thickness at 3 mm and 13 mm and age (p < 0.05). There were significant associations between the PBL and age (p < 0.001), and PBL and gender (p < 0.05). CONCLUSION: PBL might have an association with maxillary sinus lateral bone wall thickness. Further studies are needed to confirm this possible relationship. PMID- 30296785 TI - A Comparison of Simple Analytical Methods for Determination of Fluoride in Microlitre-Volume Plasma Samples. AB - : The aim was to compare potential methods for fluoride analysis in microlitre volume plasma samples containing nano-gram amounts of fluoride. METHODS: A group of 4 laboratories analysed a set of standardised biological samples as well as plasma to determine fluoride concentration using 3 methods. In Phase-1, fluoride analysis was carried out using the established hexamethyldisiloxane (HMDS) diffusion method (1 mL-aliquot/analysis) to obtain preliminary measurement of agreement between the laboratories. In Phase-2, the laboratories analysed the same samples using a micro-diffusion method and known-addition technique with 200 uL-aliquot/analysis. Coefficients of Variation (CVs) and intra-class correlation coefficients (ICCs) were estimated using analysis of variance to evaluate the amount of variation within- and between-laboratories. Based on the results of the Phase-2 analysis, 20 human plasma samples were analysed and compared using the HMDS-diffusion method and known-addition technique in Phase-3. RESULTS: Comparison of Phase-1 results showed no statistically significant difference among the laboratories for the overall data set. The mean between- and within laboratory CVs and ICCs were < 0.13 and >=0.99, respectively, indicating very low variability and excellent reliability. In Phase-2, the overall results for between-laboratory variability showed a poor CV (1.16) and ICC (0.44) for the micro-diffusion method, whereas with the known-addition technique the corresponding values were 0.49 and 0.83. Phase-3 results showed no statistically significant difference in fluoride concentrations of the plasma samples measured with HMDS-diffusion method and known- addition technique, with a mean (SE) difference of 0.002 (0.003) ug/mL. In conclusion, the known-addition technique could be a suitable alternative for the measurement of fluoride in plasma with microlitre-volume samples. PMID- 30296786 TI - Structure-Activity Relationship of the GPR55 Antagonist, CID16020046. AB - BACKGROUND/AIMS: CID16020046 blocks the effect of the lipid lysophosphatidylinositol (LPI) at its receptor, GPR55. CID16020046 and another antagonist, ML193, have been used to investigate GPR55-mediated effects of LPI on cells, tissues, and in vivo. Here we describe the structure-activity relationship of CID16020046. METHODS: Yeast or human cells were engineered to express GPR55 or control receptors. Cells were pretreated with a test agent before agonist challenge. Functional responses were quantified by yeast gene-reporter or calcium imaging. RESULTS: Three substituents around the central pyrazololactam core of CID16020046 are each tolerant to substitution without abolishing GPR55 activity. Analogues of CID16020046 with potency at GPR55 ranging >1,000-fold are described, including several lacking activity up to the top concentration tested. One analogue, compound 1 (GSK875734A), has approximately 50-fold greater potency than CID16020046 in an inverse agonist assay. CID16020046, ML193 and 2 further antagonists (ML191 and ML192) all block the effect of a surrogate agonist at human GPR55. ML193, CID16020046 and several other examples of the pyrazololactam chemotype were also shown to antagonise rat GPR55. CONCLUSION: These data confirm the utility of CID16020046 and ML193 as tools to investigate the physiological role of GPR55, and offer starting points for GPR55 antagonists with optimised pharmacokinetic or other properties. PMID- 30296787 TI - Compromised DNA Repair and Signalling in Human Granulocytes. AB - In previous studies, we showed impaired DNA repair in human monocytes. Here, we addressed the question of whether human neutrophilic granulocytes that arise from the same precursor as monocytes exhibit a similar phenotype and are impaired in repairing their DNA. We show that neutrophilic granulocytes isolated from peripheral blood display a lack of the same repair proteins that are missing in monocytes and do not show repair of their DNA when damaged by ionising radiation (IR) or chemical ROS. Contrary to T cells, we observed no decline in the number of single-strand breaks following gamma-radiation. Also, granulocytes did not show gammaH2AX foci formation while T cells and peripheral blood lymphocytes (PBL) responded. In comparison to PBL, XRCC1, PARP-1 and ligase III were not expressed and there was also no discernible signal for key damage response proteins ATM, ATR and DNA-PKCS as well as gammaH2AX in neutrophils. Time course and dose-response experiments confirmed the absence of H2AX phosphorylation after radiation treatment although an accumulation of double-strand breaks was detected in the neutral Comet assay. Overall, the data indicate that terminally differentiated neutrophilic granulocytes in the peripheral blood display strong downregulation of DNA repair and DNA damage response factors, which should be taken into account if studies with whole peripheral blood containing granulocytes are performed, causing a significant intra-experimental variation in the cellular repair capacity. PMID- 30296788 TI - State of the Art Enamel Remineralization Systems: The Next Frontier in Caries Management. AB - The principles of minimally invasive dentistry clearly dictate the need for clinically effective measures to remineralize early enamel caries lesions. While fluoride-mediated remineralization is the cornerstone of current caries management philosophies, a number of new remineralization strategies have been commercialized or are under development that claim to promote deeper remineralization of lesions, reduce the potential risks associated with high fluoride oral care products, and facilitate caries control over a lifetime. These non-fluoride remineralizing systems can be broadly categorized into biomimetic enamel regenerative technologies and the approaches that repair caries lesions by enhancing fluoride efficacy.

We assessed whether hospital doctors measure HbA1c in hospitalized patients and act consequently. METHODS: Data from patients hospitalized between January 2013 and December 2014 in a Swiss teaching hospital was collected. We assessed the frequency of HbA1c measurements and the number of newly detected prediabetes or DM. We also examined whether HbA1c values were associated with the antidiabetic drugs prescription and reporting of DM in the discharge letter. RESULTS: Of the 2618 patients studied, 298 (11.4%) had HbA1c measured, of whom 136 (45.6%) had no previous history of DM. Of the 136 patients without history of DM, 51 (37.5%) had prediabetic state and 23 (16.9%) had DM. Newly detected prediabetes or DM were reported in 5.8% (3/51) and 65.8% of cases (15/23), respectively. Only half of patients (11/23, 47.8%) with newly detected DM received antidiabetic drug treatment at discharge. Patients with newly detected DM (n=23) had a longer length of stay (median and interquartile range: 16 [9-25] versus 10 [8-16] days, p=0.028) compared to patients without DM, while no such differences were found regarding in-hospital mortality. CONCLUSIONS: Hospital doctors seldom prescribe HbA1c measurement in medical hospitalized patients. Prescription of HbA1c measurement leads to a high detection rate (53%) of (pre)DM among patients unaware of their status, but management and reporting of these conditions at discharge could be further improved. PMID- 30296789 TI - Protective Effect and Mechanism of Alprostadil in Acute Respiratory Distress Syndrome Induced by Oleic Acid in Rats. AB - BACKGROUND This study investigated the role and mechanism of alprostadil in acute respiratory distress syndrome (ARDS) induced by oleic acid (OA) in rats. MATERIAL AND METHODS Sprague-Dawley rats were randomly divided into control, OA model, and OA + Alprostadil (2.5, 5, and 10 MUg/kg, respectively) groups. The ARDS model was induced by femoral vein injection of OA, and alprostadil was administrated immediately. Lung injury was evaluated by lung wet-dry weight ratio (W/D) and histological analyses. Expressions of ACE, inflammatory mediators, apoptotic related proteins, and proteins in the MAPKs and NF-kappaB signaling pathways were determined by Western blot or immunohistochemical staining. RESULTS Compared with the control group, the OA model group had significantly increased W/D, lung injury score, and collagen deposition at 3 h after OA injection. However, alprostadil (10 MUg/kg) treatment significantly reduced OA-induced elevation of these indicators. Additionally, OA-induced expression of TNF-alpha and IL-1beta were suppressed by alprostadil. The OA-induced activation of nuclear factor (NF) kappaB p65 was also reduced by alprostadil. Furthermore, we found that Alprostadil had an inhibitory effect on the phosphorylation of JNK, ERK1/2, and p38 MAPKs. Alprostadil inhibited Bax but increased Bcl-2, indicating a suppressive role in apoptosis. Remarkably increased expression of ACE in the OA model group was observed, which was decreased by alprostadil. CONCLUSIONS Alprostadil has a protective effect on ARDS induced by OA in rats, possibly through inhibiting apoptosis, suppressing the activation of MAPKs and NF-kappaB signaling pathways, and decreasing ACE protein expression. Therefore, the use of alprostadil in clinical ARDS treatment is promising. PMID- 30296791 TI - Morin Exerts Anti-Diabetic Effects in Human HepG2 Cells Via Down-Regulation of miR-29a. AB - Diabetes mellitus is a complex metabolic disease around the world that is characterized by hyperglycemia resulting from impaired insulin secretion, insulin action, or both. MicroRNA-29a is an important regulator of insulin signaling and gluconeogenesis pathways through IRS2, PI3K and PEPCK expressions which up regulates in Diabetes. Morin is a substantial bioflavonoid which has insulin mimetic effect, and interacting with nucleic acids and proteins. In this study HepG2 cells, were exposed to high glucose to induce diabetic condition. We have determined whether high glucose stimulation might promotes miR-29a expression level in HepG2 cells and subsequently evaluated the Morin treatment effects on this state. In HepG2 cells, high glucose increases miR-29a expression level and decreases its target genes, IRS2 and PI3K expression, and increases associated downstream gene in gluconeogenic pathway, PEPCK. Morin treatment down regulates miR-29a expression level and improves insulin signaling and glucose metabolism. To confirm the inhibitory effects of Morin on miR-29a, we have transfected cells with mimic and inhibitor-miR-29a. This study for the first time identifies that Morin improves diabetic condition through down regulation of the miR-29a level, and suggest that this new inhibitor of miR-29a may be a useful biomedicine to treat diabetes.

AB - Venous thromboembolism (VTE) is a leading cause of morbidity with potentially detrimental career consequences in elite athletes. Their unique predisposing factors entail a higher-than-expected VTE incidence. Anticoagulation treatment is challenging, especially among those athletes wishing to resume their competitive activities. The authors review the current VTE treatment guidelines from the perspective of treating elite athletes. They then provide an expert opinion individualized treatment approach based on the pharmacokinetic properties of direct oral anticoagulants that permits tailoring the drug's timing to the athlete's competitive endeavors. They also present low-molecular-weight heparin as an alternative. The proposed risk management approach allows mitigation against VTE recurrence, reducing the chance of major bleeding, and honoring the athlete's self-determination to resume their career while accepting the risks involved. A shared decision making with the athlete and his/her team along with the presence of adequate resources are key components. Ultimately, the authors hope this work will serve as a stepping stone to validated VTE treatment regimens that consider the particularities of elite athletes. PMID- 30296794 TI - Enhanced Contouring of Local Flaps. AB - Scars and flaps represent a disruption of the normal skin contour, shape, and texture. Successful reconstruction of facial defects with local flaps requires prior planning to choose the correct reconstructive method. However, thorough preoperative planning should include consideration of adjunctive procedures to improve expected postoperative results as well as potential procedures to improve less-than-ideal results. Approaching facial reconstruction holistically allows the surgeon to soberly assess his/her reconstructive results and attain outstanding appearance. PMID- 30296795 TI - Widened Dorsum: Bony and Cartilaginous Contributions. AB - Creation of a pleasing dorsal nasal profile in the anterior and lateral views requires proper analysis and planning to determine the required series of steps to accomplish the desired outcome. The widened nasal dorsum is a common esthetic complaint of the patient seeking rhinoplasty. Often patients seek an unrealistic result that, if accomplished, would leave them with a restricted nasal vault and nasal airway compromise. Nasal function must be balanced with the patient and surgeon's desire to narrow the nasal dorsum. Various techniques are used to control the width of the upper third, or bony vault, and middle third, or cartilaginous vault. PMID- 30296796 TI - Facial Scar Improvement Procedures. AB - Scars are a natural part of dermal healing following lacerations, incisions, or tissue loss. The ideal scar is narrow, flat, level with surrounding tissue, and difficult for the untrained eye to see due to color match and placement parallel to relaxed skin tension lines; however, scarring that is dyspigmented, hypertrophied, widened, contracted, or atrophic can be aesthetically displeasing or causing functional limitations. When the scar has unfavorable characteristics, scar revision is often indicated and the cosmetic surgeon must be knowledgeable of the minimally invasive as well as surgical techniques to improve aesthetics, reduced reoccurrence, or correct functional limitations. PMID- 30296797 TI - Ideal Facial Relationships and Goals. AB - Analysis of the face is an essential component of facial plastic surgery. In training, we are taught standards and ideals based on neoclassical models of beauty from Greek and Roman art and architecture. In practice, we encounter a wide range of variation in patient desires and perceptions of beauty. Our goals seem to be ever shifting, yet our education has provided us with a foundation from which to draw ideals of beauty. Plastic surgeons must synthesize classical ideas of beauty with patient desires, cultural nuances, and ethnic considerations all the while maintaining a natural appearance and result. This article gives an overview of classical models of facial proportions and relationships, while also discussing unique ethnic and cultural considerations which may influence the goal for the individual patient. PMID- 30296798 TI - Surgical and Nonsurgical Techniques in Forehead Rejuvenation. AB - The periorbital and forehead regions are among the most expressive parts of the face. A thorough understanding of the complex facial anatomy and aesthetic norms are essential when evaluating and treating a patient for facial brow rejuvenation. Not only will knowledge of the anatomy enhance facial injection and surgical outcomes, but will also diminish potential complications. Combining nonsurgical and surgical techniques, including laser and skin rejuvenation, can yield the most natural and effective aesthetic brow improvements. PMID- 30296799 TI - Gender-Related Facial Surgical Goals. AB - In the last several years, there has been an increasing demand for surgical facial feminization or masculinization to treat the gender dysphoric patient. However, while aesthetic ideals for facial rejuvenation are well described and taught, there is a relative paucity of literature on how to achieve a feminine or masculine morphology. It is thus becoming increasingly important for facial plastic surgeons to understand patient goals regarding facial feminization or masculinization, and to have a systematic approach for analyzing the female and male face. PMID- 30296800 TI - Correction of the Lower Face and Neck. AB - Rejuvenation of the lower face and neck strives to reverse signs of aging while optimizing the patient's natural anatomy. Common features of an aesthetically pleasing lower face include a well-defined and appropriately balanced mandible and an acute cervicomental angle. Correction of the aging lower face and neck is accomplished through multiple surgical interventions, performed either alone or in combination. Determination of appropriate procedures is based on individual anatomic pathology. Intimate knowledge of facial anatomy and the complexity of the aging process is paramount to achieve a natural and aesthetic result. Thorough patient evaluation and counseling should precede any intervention. Specifically, the surgeon should be cognizant of the patient's skeletal structure, soft tissue distribution, muscular anatomy, and skin quality. Appropriate postoperative care and management of complications are vital to success. PMID- 30296801 TI - Correction of the Crooked Nose. AB - Successful management of the crooked nose can be a formidable task and requires a systematic approach that begins with an understanding of the patients' aesthetic desires, expectations, and functional symptoms. Dividing the nose into thirds and organizing a plan to correct each region individually can simplify the preoperative planning. There are two broad philosophical strategies of surgical management: engineering (reconstructive) and artistic (camouflaging). While the camouflaging technique is helpful for minor asymmetries, protrusions, and depressions, the engineering approach is best for more extreme corrections. The surgeon must be skilled in both approaches as either one or a combination of the two may yield the best results. Once corrected, postoperative care is essential to obtain optimal outcomes. PMID- 30296802 TI - Selecting the Best Eyelid Techniques. AB - The periorbital region is a focal point on the face. Dermatochalasis, fat herniation, blepharoptosis, brow ptosis, deep tear troughs, and malar fat pad descent are all age-related changes that occur around the eyes, and successful rejuvenation involves addressing all of these changes. Restoring a youthful, vibrant appearance to the eyes and periorbital areas can often only be accomplished with a combination of surgical and nonsurgical interventions. Facial plastic surgeons should have a comprehensive knowledge of all of these options and their applications to ensure good patient outcomes and satisfaction.

PMID- 30296804 TI - A Natural Phenolic Compound Quercetin Showed the Usefulness by Targeting Inflammatory, Oxidative Stress Markers and Augment 5-HT Levels in One of the Animal Models of Depression in Mice. AB - AIM: In the present study quercetin was studied for its role in inflammation, oxidative stress markers and 5-HT levels in unpredictable chronic mild stress (UCMS) animal model of depression. MATERIALS AND METHODS: The mice were randomized into different groups trained for UCMS protocol followed by different drug treatments. Treatments were started after 2 weeks from the start of UCMS protocol and continued up to 6 weeks. The behavioral tests such as modified forced swimming (MFST), tail suspension (TST) and open field tests were performed on week 6, at least 24 h after the last drug treatment. Behavioral tests were preceded following animal sacrifice for biochemical estimations. RESULTS: A significant decrease in swimming, climbing times and increase in immobility time in MFST and TST was observed in UCMS group. Administration of quercetin (25 mg/kg per orally (p.o) reversed these times in MFST and TST. A decrease in no. of field crossing, time spent in centre and no. of rearing were observed in UCMS group. Quercetin reduced these observations in open field test. There was a decrease in superoxide dismutase (SOD), glutathione (GSH), catalase and 5 HT levels in the brain tissue. Quercetin treatment significantly augmented SOD, GSH, catalase and 5 HT levels. Glutamate, TNF-alpha and IL-6 levels were increased in UCMS group while quercetin decreased these cytokines. CONCLUSION: Quercetin resulted antidepressant-like effect by its antioxidant, anti-inflammatory activities, reduced excitotoxicity and augmented 5 HT levels. This pointed out the usefulness of this phenolic compound as adjuvent drug along with other antidepressant drugs. PMID- 30296805 TI - Effect of Canagliflozin on Heart Function Involving Ketone Bodies in Patients with Type 2 Diabetes. AB - This report describes the effect of administration (n=3) or withdrawal (n=2) of canagliflozin, a sodium-glucose co-transporters 2 (SGLT-2) inhibitor, on cardiac function in relation to ketone bodies. Three cases received and two cases discontinued canagliflozin. Changes of heart function with ultrasonography (EF: ejection fraction and %FS: functional shortening) and cardiometabolic parameters including ketone bodies (acetoacetate/beta-hydroxybutylate) were compared at 3 months. 69, 68 and 60 years old male patients A, B and C, respectively with moderately decreased heart function received canagliflozin 100 mg/day. EF, %FS and acetoacetate/beta-hydroxybutylate levels increased. 60 and 59 years old female patients D and E with normal and borderline heart function, respectively discontinued canagliflozin 50 mg/day. EF, %FS and acetoacetate/beta hydroxybutylate levels decreased. Taken together, these results suggest that concomitant changes between ketone bodies and heart function were observed with or without canagliflzoin. This drug might have effects on cardiac function through modulating ketone bodies. PMID- 30296806 TI - Review of Clinical Pharmacokinetics of Avibactam, A Newly Approved non-beta lactam beta-lactamase Inhibitor Drug, In Combination Use With Ceftazidime. AB - Avibactam, a potent non-beta lactam beta-lactamase inhibitor, was recently approved in the USA for combination use with ceftazidime, a cephalosporin antibiotic drug. The addition of avibactam potentiates the antimicrobial drug ceftazidime, which otherwise would have been susceptible to beta-lactamases produced by variety of Gram negative pathogens. The focus of this review was to provide clinical pharmacokinetic data of avibactam to cover absorption, distribution, metabolism, and excretion aspects including any potential for avibactam to show drug-drug interactions in the clinic. Based on the review of the data, the pharmacokinetics of avibactam was generally stationary in the studied dosing regimen. The elimination half-life (approximately 1.4- 3.2 h) and volume of distribution at steady state (15.4-26.3 L) were found similar across the studies and therefore, provided the complementary pharmacokinetic attributes for combination use with ceftazidime. Renal excretion was the major pathway for the clearance of avibactam. In summary, any degree of renal dysfunction is expected to alter the pharmacokinetics of avibactam - this consideration should be factored in dosage adjustments while dosing in patients with renal impairment. Concomitant drugs that may influence renal mechanism of elimination of avibactam should be avoided and/or monitored for any impact on the pharmacokinetics of avibactam. PMID- 30296807 TI - [Extramedullary Plasmacytoma]. PMID- 30296808 TI - Analysis of Machine Learning Algorithms for Diagnosis of Diffuse Lung Diseases. AB - BACKGROUND: Diffuse lung diseases (DLDs) are a diverse group of pulmonary disorders, characterized by inflammation of lung tissue, which may lead to permanent loss of the ability to breathe and death. Distinguishing among these diseases is challenging to physicians due their wide variety and unknown causes. Computer-aided diagnosis (CAD) is a useful approach to improve diagnostic accuracy, by combining information provided by experts with Machine Learning (ML) methods. OBJECTIVES: Exploring the potential of dimensionality reduction combined with ML methods for diagnosis of DLDs; improving the classification accuracy over state-of-the-art methods. METHODS: A data set composed of 3252 regions of interest (ROIs) was used, from which 28 features were extracted per ROI. We used Principal Component Analysis, Linear Discriminant Analysis, and Stepwise Selection - Forward, Backward, and Forward-Backward to reduce feature dimensionality. The feature subsets obtained were used as input to the following ML methods: Support Vector Machine, Gaussian Mixture Model, k-Nearest Neighbor, and Deep Feedforward Neural Network. We also applied a Deep Convolutional Neural Network directly to the ROIs. RESULTS: We achieved the maximum reduction from 28 to 5 dimensions using LDA. The best classification results were obtained by DFNN, with 99.60% of overall accuracy. CONCLUSIONS: This work contributes to the analysis and selection of features that can efficiently characterize the DLDs studied. PMID- 30296809 TI - Prehospital Telemedical Emergency Management of Severely Injured Trauma Patients. AB - BACKGROUND: Trauma is a global burden. Emergency medical services (EMS) provide care for individuals who have serious injuries or suffered a major trauma. OBJECTIVE: This paper provides a comprehensive overview of telemedicine applications in prehospital trauma care. METHODS: We conducted a systematic review according to PRISMA guidelines. We identified articles by electronic database search (PubMed, EMBASE, the Cochrane Library, CINAHL, SpringerLink, LIVIVO, DARE, IEEE Xplore, Google Scholar and ScienceDirect) using keywords related to prehospital settings, ambulance, telemedicine and trauma. Search terms and inclusion criteria were specified a priori by the PICOS template and revised throughout a configurative approach iteratively, to outline the complexity and variety of different telemedical concepts. RESULTS: A final sample of 15 records was systematically selected. Most interventions were piloted and/or evaluated in Germany for trauma victims in prehospital settings. Six studies were simulated scenarios. Telemedical assistance (TMA) via real-time telemetry systems (RTS), enabling video and audio conferencing between EMS by tele-emergency physicians (TEP) were associated with a higher treatment quality and a shorter time-to treatment in invasive procedures. By initiating in-hospital preparations based on telemedical prehospital notification (TPN), loss of information during the clinical handover was reduced and in-hospital protocols were activated with high accuracy. Remotely guided ultrasound (Tele-Ultrasound) by TEP showed an overall high diagnostic accuracy in simulations. Technical solutions were reliable, seemed practical and auspicious. CONCLUSION: The review indicates that TMA and TPN are accompanying telemedical concepts in out-of-hospital trauma care. Well designed populated studies are needed to fully assess the effect of telemedicine in acute trauma care. Therefore, evidence regarding the effectiveness of telemedicine in prehospital setting for trauma patients is still limited.

PMID- 30296811 TI - Peroral endoscopic myotomy (POEM) is effective in treatment of noncardiac chest pain caused by hypercontractile esophageal motility disorders: results of the POEM-HYPE-Study. AB - BACKGROUND: Noncardiac chest pain (NCCP) is recurrent angina pectoris-like pain without evidence of coronary heart disease in conventional diagnostic evaluation. In gastroenterology, managing of patients with NCCP is ambiguous to detect gastroesophageal reflux and hypercontractile esophageal motility disorders. Recently, peroral endoscopic myotomy (POEM) was established as treatment option in achalasia. However, limited data exist on the effectivity of POEM in NCCP with hypercontractile esophageal motility disorders. MATERIAL AND METHODS: In this prospective study (POEM-HYPE), we evaluated 14 patients with NCCP and hypercontractile esophageal motility disorders (type III achalasia, n = 7; hypercontractile esophagus, n = 6; distal esophageal spasm, n = 1). All patients underwent standardized diagnostic work-up including esophagogastroduodenoscopy with esophageal biopsies, high-resolution esophageal manometry, and combined intraluminal impedance and pH testing before and 3 weeks after POEM. A standardized symptom questionnaire was disposed before POEM, 3 weeks after, and every 6 months after the POEM. RESULTS: After POEM, 12 patients showed significant symptom relief (pre-Eckardt score: 7.78 +/- 1.47, 3 weeks post: 1.64 +/- 1.44, 6 months: 2.0 +/- 1.84 and 1.86 +/- 1.89 after 15.0 +/- 10.0 months post-intervention). High-resolution manometry showed significant reduction in integrated relaxation pressure (pre-POEM: 24.74 +/- 18.9 mm Hg, post-POEM: 13.8 +/- 16.5 mm Hg) and distal contractile integral (pre-POEM: 2880 +/- 3700 mmHg*s*cm, post-POEM: 1109 +/- 1042 mmHg*s*cm). One lesion of the submucosal tunnel occurred as a moderate adverse event and was handled endoscopically. The long-term clinical success rate was 85.7 %. No severe gastroesophageal reflux occurred after interventions. Two patients required secondary therapy with injection of botulinum toxin in the tubular esophagus and balloon dilation. CONCLUSION: The results suggest that POEM is an effective and safe therapeutic option for patients with NCCP and hypercontractile esophageal motility disorders. PMID- 30296812 TI - Surgical therapy of chronic pancreatitis: clinical results and health-related quality of life. AB - INTRODUCTION: There are several well-established surgical procedures for the treatment of chronic pancreatitis (CP). The present study seeks to evaluate the perioperative and long-term outcome of these procedures. METHODS: All patients who had undergone pancreaticoduodenectomy (PD), duodenum-preserving pancreatic head resection (DPPHR), and distal pancreatectomy (DP) for CP were retrospectively analyzed with regards to the perioperative outcome and long-term survival. Health-related quality of life (HRQoL) was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire. RESULTS: There were 145 patients available for analysis. Major complications (grade IIIb-V) occurred in 19 %, in-hospital mortality was 4.2 %, and 90-day mortality was 3 % with no differences between the different resection groups (all p > 0.05). Ten-year survival was 58 % and was highest in the DP group (100 %) but without statistical significance (p = 0.72). The response rate of the HRQoL assessment was 45 % (65 of 145). There was a significant improvement with regards to pain and HRQoL of all resection groups compared to the preoperative group (all p < 0.05). With respect to HRQoL and pain relief, the PD, DPPHR, and DP did not differ significantly. DISCUSSION: Surgical therapy of CP can be performed safely. The 3 different types of resection performed equally with regards to complications and HRQoL. PMID- 30296813 TI - Isolated Tricuspid Valvectomy: A Series of cases with Intravenous Drug Abuse Associated Tricuspid Valve Endocarditis. AB - INTRODUCTION: Surgical management for tricuspid valve (TV) endocarditis is usually TV repair or replacement. When repair is not feasible, and concerns for patient recidivism preclude TV replacement, tricuspid valvectomy without replacement is an option to alleviate symptoms and allow time for addiction management. METHODS: We reviewed our institution's experience with isolated tricuspid valvectomy for cases of intravenous drug use (IVDU)-associated endocarditis (n = 7) from 2009 to 2017. RESULTS: The decision for tricuspid valvectomy was based on each patient's comorbid condition and realization of active IVDU. This intervention resulted in 100% perioperative and mid-term survival with a mean follow-up of 25.4 months. One patient required a valve replacement in the long term only after appropriate substance abuse management was completed. CONCLUSION: Cardiac surgeons increasingly encounter patients with active endocarditis who suffer from IVDU addiction. Drug addiction increases the risk for recurrent endocarditis and requires an effective management plan. Multidisciplinary endocarditis care teams may play a pivotal role in improving outcomes by better addressing addiction treatment. PMID- 30296814 TI - New Device for the Treatment of Functional Ischemic Mitral Regurgitation: Proof of Concept in an In Vitro Model. AB - BACKGROUND: Optimal surgical treatment of functional ischemic mitral regurgitation (FIMR) is still controversy. Due to the underlying pathophysiology, stand-alone ring annuloplasty is assumed with a high recurrence rate of mitral regurgitation, thus additional subvalvular repair techniques might improve the results. This in vitro study introduces a new device for subvalvular mitral valve repair. METHODS: We developed a new device for subvalvular mitral valve repair, consisting of two frames for papillary muscle (PM) attachment, which are connected with two holding bars serving for fixation of the device on an annuloplasty ring. In the first experimental run, porcine mitral valves including the chordae tendineae and PMs were fixated on a holding device, consisting of a holding ring simulating mitral annulus dilation and height-adjustable frames for PM attachment simulating leaflet tethering. In vitro regurgitant volume was determined in a pulse duplicator. Afterward, the frames for PM attachment were replaced by our newly developed device and the measurements were repeated. RESULTS: In the model simulating FIMR, the regurgitant volume was 44.3 +/- 12.38 mL/stroke. After subvalvular reconstruction with our new device, the regurgitant volume was significantly reduced to 33.1 +/- 11.68 mL/stroke (p = 0.009). CONCLUSION: In this specific in vitro model, our new device for subvalvular mitral valve reconstruction led to a significant reduction of the regurgitant volume, thus representing a promising technique to potentially improve the results of mitral reconstruction in ischemic functional mitral valve regurgitation. Additional studies are required to further investigate and improve our device. PMID- 30296815 TI - Association of Platelet-to-Lymphocyte Ratio and Neutrophil-to-Lymphocyte Ratio with the Risk of Thromboembolism and Mortality in Patients with Cancer. AB - Patients with cancer are at risk of developing venous and arterial thromboembolism (VTE and ATE). Elevated platelet-to-lymphocyte (PLR) and neutrophil-to-lymphocyte ratios (NLR) have been suggested as potential biomarkers for cancer-associated chronic inflammation, VTE and mortality. We investigated the association between PLR and NLR with VTE, ATE and mortality in patients with cancer. Within a prospective cohort study, we followed-up patients with newly diagnosed or progressing cancer for objectively confirmed, symptomatic VTE, ATE and death. Fine and Gray competing-risk regression was used to model the risk of VTE and ATE. Overall survival was analysed with Kaplan-Meier estimators. From 2003 to 2013, 1,469 patients with solid cancer (median age: 61 years; 47.3% female) were recruited and followed for 2 years. Overall, 128 (8.7%) patients developed VTE, 41 (2.8%) ATE and 643 (43.8%) patients died. The sub-distribution hazard ratios (SHRs) for VTE per doubling of PLR and NLR were 1.0 (95% confidence interval [CI]: 0.8-1.3, p = 0.899) and 1.2 (1.0-1.4, p = 0.059), respectively. For ATE, the SHR per doubling of PLR and NLR were 1.0 (0.7-1.5, p = 0.940) and 1.2 (0.9-1.6, p = 0.191), respectively. A higher PLR (hazard ratio [HR] per doubling = 1.5, 1.4-1.7, p < 0.001) and a higher NLR (HR per doubling = 1.5, 1.4 1.7, p < 0.001) were associated with an increased risk of mortality after adjusting for age, sex and cancer stage. There was no statistically significant association between NLR and VTE occurrence in patients with cancer. Neither PLR nor NLR were associated with the risk of ATE. Both elevated PLR and NLR were independently associated with a twofold increased risk of mortality.

PMID- 30296817 TI - Venous Thromboembolism in Women Undergoing Assisted Reproductive Technologies: Data from the RIETE Registry. AB - Venous thromboembolism (VTE) during or after assisted reproductive technologies (ART) is predicted to rise due to the increased number of women undergoing this technique. We present data collected in the RIETE registry up to October 2016. Overall, 41 (0.6%) out of 6,718 women of childbearing age with VTE had an ART related event. Most of them underwent autologous ART cycles; 23 had isolated deep vein thrombosis (DVT) (56.1%), 12 isolated pulmonary embolism (PE) (29.3%) and 6 simultaneous occurrence of both the events (14.6%). VTE occurred in 20 successful and 21 unsuccessful (i.e. not resulting in a clinical pregnancy) ART cycles. No recurrence was observed at 90 days. Logistic regression showed that isolated PE was significantly more frequent than DVT alone or combined with PE in unsuccessful in vitro fertilization (IVF) (odds ratio [OR]: 4.13, 95% confidence interval [CI]: 1.4-12.4), as well as in contraceptive users (OR: 2.96, 95% CI: 1.95-4.5) and in puerperium (OR: 1.96, 95% CI: 1.16-3.3). After grouping isolated PE and DVT + PE, we found that PE was significantly more frequent in women with unsuccessful IVF and higher body mass index (OR: 5.0, 95% CI: 1.2-20.7 and OR: 1.0, 95%CI: 1.0-1.1, respectively). These data document a higher risk of PE in unsuccessful cycles than in successful ones. The risk is higher than that observed during pregnancy, puerperium and contraception. PMID- 30296818 TI - Prospective Study of Endogenous Hormones and Incidence of Venous Thromboembolism: The Atherosclerosis Risk in Communities Study. AB - Exogenous hormone treatments in women (oral contraceptives and hormone replacement therapy [HRT]) are established risk factors for venous thromboembolism (VTE), but less is known about associations between plasma levels of endogenous hormones and VTE risk. We examined the association of baseline dehydroepiandrosterone sulphate (DHEAS), testosterone and sex hormone-binding globulin (SHBG) with risk of future VTE in men and post-menopausal women in the Atherosclerosis Risk in Communities Study. Testosterone, DHEAS and SHBG were measured in plasma samples collected in 1996 to 1998. Cox proportional hazards models were used to estimate hazard ratios for incident VTE adjusting for age, race/ethnicity, body mass index, height, smoking, estimated glomerular filtration rate and C-reactive protein. All analyses were stratified by sex and by current HRT use in women. Among 3,051 non-HRT-using women, 1,414 HRT-using women and 3,925 men at risk at baseline, 184, 62 and 206 experienced incident VTE after a median follow-up of 17.6 years. Plasma hormones were not associated with incidence of VTE among men and non-HRT-using women, although lower plasma DHEAS, when modelled using quartiles or restricted cubic splines, was associated with higher risk of VTE among HRT-using women. This study does not support the existence of an important association between plasma concentrations of endogenous testosterone, DHEAS or SHBG with risk of VTE in middle-aged to older men or post menopausal women not using HRT.

METHODS: Cross-sectional analysis of the 2011/12 adult New Zealand Health Survey (n=12,596) was undertaken. Logistic regression was used to examine associations between experience of racism (by a health professional and other experiences of racism [ever]) and unmet need for a general practitioner and satisfaction with a usual medical centre in the past year. RESULTS: Experience of racism by a health professional and other forms of racism were higher among Maori, Pacific and Asian groups compared to European/Other. Both racism measures were associated with higher unmet need (health professional racism adjusted OR 3.52, 95%CI 2.42-5.11; other racism OR 2.21, 95%CI 1.78-2.75) and lower satisfaction with a usual medical centre (health professional racism adjusted OR 0.25, 95%CI 0.15-0.34; other racism OR 0.60, 95%CI 0.45-0.79). CONCLUSIONS: Racism may act as a barrier to, and influence the quality of, healthcare. Implications for public health: Addressing racism as a public health issue and major driver of inequities in healthcare and health outcomes is required within the health sector and wider society. PMID- 30296820 TI - Carbon pricing of food in Australia: an analysis of the health, environmental and public finance impacts. AB - OBJECTIVE: To estimate the impact of integrating the price of greenhouse gas emissions into the price of food commodities on dietary and weight-related risk factors and associated disease burden in Australia, as well as on national emissions reductions and public revenues. METHODS: We used country-specific data for Australia to build a coupled modelling framework that includes economic, environmental and health analyses. Data sources included the 2011-12 Australian food and nutrition survey, meta-analysis of food-related lifecycle emissions, and price and income elasticities. Consumption-related changes in disease burden were calculated using a comparative risk assessment framework with 11 disease states and seven diet and weight-related risk factors. RESULTS: Including a price of $23 per tonne of carbon dioxide equivalent (tCO2-eq) - the starting price of the former Australian carbon pricing mechanism - into the price of food commodities in our model simulations led to 49,500 avoided disability-adjusted life years (DALYs) (95% confidence interval [CI] 43,200-55,200). Food-related greenhouse gas emissions were reduced by 6% (2.3 MtCO2-eq), and greenhouse gas tax revenues amounted to $866 million. CONCLUSION: Incorporating the price of food-related greenhouse gas emissions into the price of food commodities in Australia could be beneficial for population health, while generating public finance revenues and supporting Australia's emission-reduction commitment. Implications for public health: Climate policies that integrate the price of greenhouse gas emissions into the price of food commodities in Australia are compatible with public health objectives to reduce diet-related disease mortality. PMID- 30296821 TI - Where children play most: physical activity levels of school children across four settings and policy implications. AB - OBJECTIVE: This study examined physical activity levels among 2,296 Queensland school children in the school, club sport, active transport and free time settings. Childhood physical activity contributes to musculoskeletal strength, psychosocial benefits and cardiovascular health. METHODS: Data were collected from parents by computer-assisted telephone interview on an annual preventive health monitoring survey conducted by the Queensland Government. RESULTS: Parents reported that children achieved the largest proportions of their physical activity in school (33%) or their free time (42%). Moderate participation levels were reported for active transport and organised sport and these activities contributed lower proportions to total physical activity (10% and 15%, respectively). After adjusting for age and sex, living in a family with higher levels of activity and with a parent that knows physical activity guidelines was associated with higher activity levels. Implications for public health: Increasing physical activity in settings where less active children are already participating, specifically in school settings and during free time, may have more immediate benefits than encouraging children to be active in new settings. Many children achieve seven or more hours of physical activity weekly but do not meet the physical activity guideline criterion of 60 minutes of physical activity daily; consequently, quantifying physical activity solely against the guidelines may underestimate children's physical activity. PMID- 30296822 TI - Collaborative population health planning between Australian primary health care organisations and local government: lost opportunity. AB - OBJECTIVE: To examine the strength and extent of collaborations between primary health care organisations and local government in population health planning. METHODS: Methods included: a) online surveys with Medicare Locals (n=210) and Primary Health Networks (n=66), comparing the two using two-level mixed models; b) interviews with Medicare Local (n=50) and Primary Health Network (n=55) executives; c) interviews with members of local government associations and Primary Health Network board members with local government experience (n=7); and d) review of 54 Medicare Local and 31 Primary Health Network publicly available annual reports. RESULTS: Despite partnership being a policy objective for Medicare Locals/ Primary Health Networks, they reported limited time and financial support for collaboration with local government. Organisational capacity and resources, supportive governance and public health legislation mandating a role for local governments were critical to collaborative planning. CONCLUSIONS: Local government has the potential to tackle social factors affecting health; therefore, their inclusion in population health planning is valuable. Legislative mandates would help to achieve this, and PHNs require a stronger Federal Government mandate backed by sufficient resources and a governance structure that supports collaboration. Implications for public health: Improving primary health care and local government collaboration has great potential to improve the quality of health planning and action on social determinants, thus advancing population health and health equity. PMID- 30296823 TI - How much free sugar do Australians consume? Findings from a national survey. AB - OBJECTIVE: To identify the characteristics of Australian adults exceeding the World Health Organization's free sugar (FS) intake recommendations of <10% and compare the sources of FS among those exceeding (high FS consumers) and complying (low FS consumers) with the recommendations. METHOD: Nationally weighted data from the Australian National Nutrition and Physical Activity Survey 2011-12 was used to describe the proportions of FS consumption and sources of FS among adults aged >=18 years (n=9,435) across demographic, socioeconomic and health behavioural subgroups. Six categories of food groups likely to contain FS were generated and analysed. RESULTS: Almost half of all adults (47%) were high FS consumers. More than one-third of adults in each demographic, socioeconomic and health behaviour subgroup were high FS consumers. Of the food groups containing FS, beverages contributed the most FS (37%), particularly for young adults (48%). High FS consumers obtained twice as much FS from beverages (42%) than low FS consumers (21%). A reverse age gradient was observed for the FS sourced from beverages. CONCLUSIONS: Almost half the Australians surveyed exceeded the FS intake recommendations. Sugary beverages were the largest source of FS, with young adults being the highest consumers. Implications for public health: Whole population strategies targeting beverages could possibly reduce Australia's high sugar intake. PMID- 30296825 TI - Phenylnitrene Radical Cation Rearrangements. AB - The electronic structure and the rearrangements of the phenylnitrene radical cation C6H5N.+ 2.+ have been investigated at DFT and CASPT2(7,9) levels of theory. The 2B2 state has the lowest energy of five identified electronic states, and it can undergo ring expansion to the 1-azacycloheptetetraene radical cation 4.+ with an activation energy of ca. 28 kcal/mol. Ring opening and recyclization provide a route to 5-cyanocyclopentadiene radical cation 8.+, which may undergo facile 1,5-hydrogen shifts. The 2-, 3-, and 4-pyridylcarbene radical cations 31.+, 35.+ , and 39.+ interconvert with the phenylnitrene radical cation via azacycloheptatetraenes with activation barriers <35 kcal/mol. The carbene-carbene and carbene-nitrene rearrangements, ring expansions, ring contractions, ring openings (e.g., to cyanopentadienylidene 28.+), and cyclizations taking place in all these radical cations are completely analogous to the thermal and photochemical rearrangements. PMID- 30296824 TI - A Thermodynamic Model for Multivalency in 14-3-3 Protein-Protein Interactions. AB - Protein-protein interactions (PPIs) are at the core of molecular control over cellular function. Multivalency in PPI formation, such as via proteins with multiple binding sites and different valencies, requires fundamental understanding to address correlated challenges in pathologies and drug development. Thermodynamic binding models are needed to provide frameworks for describing multivalent PPIs. We established a model based on ditopic host-guest systems featuring the effective molarity, a hallmark property of multivalency, as a prime parameter governing the intramolecular binding in divalent interactions. By way of illustration, we study the interaction of the bivalent 14-3-3 protein scaffold with both the nonavalent CFTR and the hexavalent LRRK2 proteins, determining the underlying thermodynamics and providing insights into the role of individual sites in the context of the multivalent platform. Fitting of binding data reveals enthalpy-entropy correlation in both systems. Simulations of speciations for the entire phosphorylated protein domains reveal that the CFTR protein preferably binds to 14-3-3 by combinations including the strongest binding site pS768, but that other binding sites take over when this site is eliminated, leading to only a minor decrease in total affinity for 14-3-3. For LRRK2, two binding sites dominate the complex formation with 14-3-3, but the distantly located pS1444 site also plays a role in complex formation. Thermodynamic modeling of these multivalent PPIs allowed analyzing and predicting the effects of individual sites regarding their modulation via, for example, (de)phosphorylation or small-molecule targeting. The results specifically bring forward the potential of PPI stabilization, as an entry for drug discovery for multivalent PPIs. PMID- 30296826 TI - Fluorescent Gold Nanocluster-Based Sensor Array for Nitrophenol Isomer Discrimination via an Integration of Host-Guest Interaction and Inner Filter Effect. AB - The rapid discrimination of nitrophenol isomers has been a long-standing challenge because of the tiny structural differences among the isomers. In this study, a fluorescent sensor array based on three different-color emitting gold nanoclusters (Au NCs) that were functionalized with three different ligands and a cocapping ligand beta-cyclodextrin (beta-CD) has been constructed for the facile discrimination of three nitrophenol isomers via the linear discriminant analysis of isomer-induced fluorescence quenching patterns. The fluorescence quenching occurs in two steps: first, beta-CDs adsorb nitrophenol isomers onto the surface of Au NCs via a host-guest interaction; second, each nitrophenol isomer quenches the fluorescence of a specific type of Au NCs through diverse inner filter effect. The different binding affinities between beta-CD and each nitrophenol isomer, as well as the distinct quenching efficiencies of the isomers on the fluorescence of each Au NCs, enable an excellent discrimination of the three isomers at a concentration of 5 MUM, when linear discriminant and hierarchical cluster analyses were smartly combined. In addition, even a mixture of two isomers could be distinguished with the proposed sensor array. The practicability of this developed sensor array is validated by a high accuracy (98.0%) examination of 51 unknown samples containing a single isomer or a mixture of two isomers. PMID- 30296827 TI - Coating 3D Printed Polycaprolactone Scaffolds with Nanocellulose Promotes Growth and Differentiation of Mesenchymal Stem Cells. AB - 3D printed polycaprolactone (PCL) has potential as a scaffold for bone tissue engineering, but the hydrophobic surface may hinder optimal cell responses. The surface properties can be improved by coating the scaffold with cellulose nanofibrils material (CNF), a multiscale hydrophilic biocompatible biomaterial derived from wood. In this study, human bone marrow-derived mesenchymal stem cells were cultured on tissue culture plates (TCP) and 3D printed PCL scaffolds coated with CNF. Cellular responses to the surfaces (viability, attachment, proliferation, and osteogenic differentiation) were documented. CNF significantly enhanced the hydrophilic properties of PCL scaffolds and promoted protein adsorption. Live/dead staining and lactate dehydrogenase release assays confirmed that CNF did not inhibit cellular viability. The CNF between the 3D printed PCL strands and pores acted as a hydrophilic barrier, enhancing cell seeding efficiency, and proliferation. CNF supported the formation of a well-organized actin cytoskeleton and cellular production of vinculin protein on the surfaces of TCP and PCL scaffolds. Moreover, CNF-coated surfaces enhanced not only alkaline phosphatase activity, but also collagen Type-I and mineral formation. It is concluded that CNF coating enhances cell attachment, proliferation, and osteogenic differentiation and has the potential to improve the performance of 3D printed PCL scaffolds for bone tissue engineering. PMID- 30296828 TI - Molecular Bottlebrushes as Novel Materials. AB - Molecular bottlebrushes are building blocks for the design of unique polymeric materials whose physical properties are fundamentally governed by their densely grafted structures. Recent developments in the area of reversible deactivation radical polymerization enabled facile and effective control over multiple molecular parameters. Owing to large molecular size, anisotropic conformation, and reduced chain entanglement, molecular bottlebrushes have empowered various applications that are challenging to achieve with linear polymers. In this Review, we focus on determining correlations between brushlike architectures and materials properties. PMID- 30296829 TI - Zwitterionic Osmolytes Resurrect Electrostatic Interactions Screened by Salt. AB - Many cells synthesize significant quantities of zwitterionic osmolytes to cope with the osmotic stress induced by excess salt. In addition to their primary role in balancing osmotic pressure, these osmolytes also help stabilize protein structure and restore enzymatic activity compromised by high ionic strength. This osmoprotective effect has been studied extensively, but its electrostatic aspects have somehow escaped the mainstream. Here, we report that, despite their overall neutrality, zwitterions may dramatically affect electrostatic interactions in saline solutions of biological relevance. Using atomic force microscopy, we study the combined effect of osmolytes and salts on electrostatic interactions between two negatively charged silica surfaces in mixtures of five salts (NaCl, KCl, CsCl, MgCl2, and CaCl2) and five zwitterionic osmolytes (betaine, proline, trimethylamine N-oxide, glycine, and sarcosine) as a function of solutes concentration and pH. All osmolytes are found to counteract the screening effect of salt on electrostatic repulsion, albeit to a different extent. They do so by both increasing the screening length shortened by added salts and by desorbing bound protons and cations, hence enhancing the negative surface charge. Both effects are traced to the osmolytes' higher molecular polarizability compared with water. In addition to this direct effect on the solution's dielectric constant, we identify an osmolytic Hofmeister effect with the more hydrophobic osmolytes more efficiently desorbing weakly hydrated cations from weakly hydrated silica and the less hydrophobic osmolytes better desorbing strongly hydrated cations from strongly hydrated silica. The combined results shed light on Coulomb interactions in a more realistic model of the cytosol, a relatively unexplored territory. PMID- 30296830 TI - Ionization of Ammonia Nanoices with Adsorbed Methanol Molecules. AB - Large ammonia clusters represent a model system of ices that are omnipresent throughout the space. The interaction of ammonia ices with other hydrogen-boding molecules such as methanol or water and their behavior upon an ionization are thus relevant in the astrochemical context. In this study, ammonia clusters (NH3) N with the mean size N ~ 230 were prepared in molecular beams and passed through a pickup cell in which methanol molecules were adsorbed. At the highest exploited pickup pressures, the average composition of (NH3) N(CH3OH) M clusters was estimated to be N: M ~ 210:10. On the other hand, the electron ionization of these clusters yielded about 75% of methanol-containing fragments (NH3) n(CH3OH) mH+ compared to 25% contribution of pure ammonia (NH3) nH+ ions. On the basis of this substantial disproportion, we propose the following ionization mechanism: The prevailing ammonia is ionized in most cases, resulting in NH4+ core solvated most likely with four ammonia molecules, yielding the well-known "magic number" structure (NH3)4NH4+. The methanol molecules exhibit a strong propensity for sticking to the fragment ion. We have also considered mechanisms of intracluster reactions. In most cases, proton transfer between ammonia units take place. The theoretical calculations suggested the proton transfer either from the methyl group or from the hydroxyl group of the ionized methanol molecule to ammonia to be the energetically open channels. However, the experiments with selectively deuterated methanols did not show any evidence for the D+ transfer from the CD3 group. The proton transfer from the hydroxyl group could not be excluded entirely or confirmed unambiguously by the experiment.

AB - Sequential inter- and intramolecular [3 + 2] cycloadditions of azomethine ylides are developed for the one-pot and diastereoselective synthesis of highly condensed heterocyclic systems containing pyrrolidine and up to seven stereocenters. It has high synthetic efficiency and operational simplicity, and only water was generated as a byproduct. PMID- 30296832 TI - Adipose-Derived Mesenchymal Stromal Cells Persist in Tissue-Engineered Vocal Fold Replacement in Rabbits. AB - OBJECTIVES:: Cell therapies using mesenchymal stromal cells (MSCs) have been proposed as a promising new tool for the treatment of vocal fold scarring. However, the mechanisms by which MSCs promote healing as well as their duration of survival within the host vocal fold have yet to be defined. The aim of this work was to assess the persistence of embedded MSCs within a tissue-engineered vocal fold mucosal replacement in a rabbit model of vocal fold injury. METHODS:: Male rabbit adipose-derived MSCs were embedded within a 3-dimensional fibrin gel, forming the cell-based outer vocal fold replacement. Four female rabbits underwent unilateral resection of vocal fold epithelium and lamina propria and reconstruction with cell-based outer vocal fold replacement implantation. Polymerase chain reaction and fluorescent in situ hybridization for the sex determining region of the Y chromosome (SRY-II) in the sex-mismatched donor recipient pairs sought persistent cells after 4 weeks. RESULTS:: A subset of implanted male cells was detected in the implant site at 4 weeks. Many SRY-II negative cells were also detected at the implant site, presumably representing native female cells that migrated to the area. No SRY-II signal was detected in contralateral control vocal folds. CONCLUSIONS:: The emergent tissue after implantation of a tissue-engineered outer vocal fold replacement is derived both from initially embedded adipose-derived stromal cells and infiltrating native cells. Our results suggest this tissue-engineering approach can provide a well integrated tissue graft with prolonged cell activity for repair of severe vocal fold scars. PMID- 30296833 TI - Disseminated Intravascular Coagulation: An Update on Pathogenesis, Diagnosis, and Therapeutic Strategies. AB - Disseminated intravascular coagulation (DIC) is an acquired clinicobiological syndrome characterized by widespread activation of coagulation leading to fibrin deposition in the vasculature, organ dysfunction, consumption of clotting factors and platelets, and life-threatening hemorrhage. Disseminated intravascular coagulation is provoked by several underlying disorders (sepsis, cancer, trauma, and pregnancy complicated with eclampsia or other calamities). Treatment of the underlying disease and elimination of the trigger mechanism are the cornerstone therapeutic approaches. Therapeutic strategies specific for DIC aim to control activation of blood coagulation and bleeding risk. The clinical trials using DIC as entry criterion are limited. Large randomized, phase III clinical trials have investigated the efficacy of antithrombin (AT), activated protein C (APC), tissue factor pathway inhibitor (TFPI), and thrombomodulin (TM) in patients with sepsis, but the diagnosis of DIC was not part of the inclusion criteria. Treatment with APC reduced 28-day mortality of patients with severe sepsis, including patients retrospectively assigned to a subgroup with sepsis-associated DIC. Treatment with APC did not have any positive effects in other patient groups. The APC treatment increased the bleeding risk in patients with sepsis, which led to the withdrawal of this drug from the market. Treatment with AT failed to reduce 28-day mortality in patients with severe sepsis, but a retrospective subgroup analysis suggested possible efficacy in patients with DIC. Clinical studies with recombinant TFPI or TM have been carried out showing promising results. The efficacy and safety of other anticoagulants (ie, unfractionated heparin, low-molecular-weight heparin) or transfusion of platelet concentrates or clotting factor concentrates have not been objectively assessed. PMID- 30296834 TI - Awareness and understanding of dementia in South Asians: A synthesis of qualitative evidence. AB - Background Despite a growing elderly South Asian population, little is known about the experience of diagnosis and care for those living with dementia. There have been a number of individual qualitative studies exploring the experiences of South Asian people living with dementia and their carers across different contexts. There has also been a growing interest in synthesizing qualitative research to systematically integrate qualitative evidence from multiple studies to tell us more about a topic at a more abstract level than single studies alone. The aim of this qualitative synthesis was to clearly identify the gaps in the literature and produce new insights regarding the knowledge and understanding of the attitudes, perceptions, and beliefs of the South Asian community about dementia. Methods Following a systematic search of the literature, included qualitative studies were assessed by two independent reviewers for methodological quality. Data were extracted and pooled using the Joanna Briggs Institute Qualitative Assessment and Review Instrument (QARI). Findings were synthesized using the Joanna Briggs Institute approach to qualitative synthesis by meta aggregation. Results Seventeen papers were critically appraised, with 13 meeting the inclusion criteria. Participants were mostly of South Asians of Indian background; followed by Pakistani with a few Sri Lankans. Missing South Asian countries from the current evidence base included those from Bangladesh, Bhutan, Maldives, and Nepal. Three meta-synthesis themes emerged from the analysis: (1) a poor awareness and understanding of dementia, (2) the experience of caregiving, and (3) the attitudes toward dementia care provision. Conclusions A consistent message from this qualitative synthesis was the limited knowledge and understanding of dementia amongst the South Asians. Whilst symptoms of dementia such as 'memory loss' were believed to be a part of a normal ageing process, some South Asian carers viewed dementia as demons or God's punishments. Most studies reported that many South Asians were explicit in associating stigmas with dementia. PMID- 30296835 TI - Prognostic Significance of Platelet Recovery in Myelodysplastic Syndromes With Severe Thrombocytopenia. AB - Severe thrombocytopenia is a serious condition that frequently arises in patients with myelodysplastic syndrome (MDS) and is associated with poor prognosis. Few studies have investigated the prognostic significance of platelet recovery in patients with MDS having thrombocytopenia. We retrospectively analyzed 117 patients with de novo MDS complicated with thrombocytopenia (platelet count [PLT] < 100 * 109/L). Patients received decitabine treatment (schedule A) or decitabine followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT; schedule B). Severe thrombocytopenia (PLT < 20 * 109/L), identified in 31 (26.5%) patients, was associated with poor survival. The PLT increased significantly after decitabine treatment in the 2 groups. Patients with thrombocytopenia treated with schedule B showed a superior prognosis compared to those treated with schedule A. On analysis of overall survival by platelet response in patients with severe thrombocytopenia, a significant survival advantage was observed in patients who achieved a platelet response, who would further benefit from allo HSCT following decitabine therapy. The results indicate a potentially favorable prognostic impact of platelet response achieved with decitabine. Patients with MDS having severe thrombocytopenia may benefit from the effective recovery of platelets and further allo-HSCT following decitabine therapy. PMID- 30296836 TI - Mapping Genes Is Good for You. AB - I abandoned my original career choice of high school teaching to pursue dentistry and soon abandoned that path for genetics. The latter decision was due to a challenge by a professor that led to me reading Nobel speeches by pioneer geneticists before I had formal exposure to the subject. Even then, I was 15 years into my career before my interest in rodent genomes gave way to mapping cattle genes. Events behind these twists and turns in my career path comprise the first part of this review. The remainder is a review of the development of the field of bovine genomics from my personal perspective. I have had the pleasure of working with outstanding graduate students, postdocs, and colleagues to contribute my small part to a discipline that has evolved from a few individuals mapping an orphan genome to a discipline underlying a revolution in animal breeding.

PMID- 30296837 TI - Ethnic differences in hypertension prevalence and contributing determinants - the HELIUS study. AB - AIMS: There are important ethnic differences in the prevalence of hypertension and hypertension-mediated cardiovascular complications, but there is ongoing debate on the nature of these differences. We assessed the contribution of lifestyle, socio-economic and psychosocial variables to ethnic differences in hypertension prevalence. METHODS: We used cross-sectional data from the Healthy Life In an Urban Setting (HELIUS) study, including 21,520 participants aged 18-70 years of South-Asian Surinamese ( n = 3032), African Surinamese ( n = 4124), Ghanaian ( n = 2331), Turkish ( n = 3594), Moroccan ( n = 3891) and Dutch ( n = 4548) ethnic origin. Ethnic differences in hypertension prevalence rates were examined using logistic regression models. RESULTS: After adjustment for a broad range of variables, significant higher hypertension prevalence compared to the Dutch population remained in Ghanaian men (odds ratio 2.62 (95% confidence interval 2.14-3.22)) and women (4.16 (3.39-5.12)), African Surinamese men (1.62 (1.37-1.92)) and women (2.70 (2.29-3.17)) and South-Asian Surinamese men (1.22 (1.15-1.46)) and women (1.84 (1.53-2.22)). In contrast, Turkish men (0.72 (0.60 0.87)) and Moroccan men (0.50 (0.41-0.61)) and women (0.57 (0.46-0.71)) had a lower hypertension prevalence compared with the Dutch population. The differences in hypertension prevalence were present across different age groups and persisted after stratification for body mass index and waist-to-hip ratio. CONCLUSION: Large ethnic differences in hypertension prevalence exist that are already present in young adulthood. Adjustment for common variables known to be associated with a higher risk of hypertension explained the higher adjusted prevalence rates among Turks and Moroccans, but not in African and South-Asian descent populations who remained to have a higher rate of hypertension compared to the Dutch host population.

PMID- 30296839 TI - Water quality comparison between a supply network and household reservoirs in one of the oldest cities in Brazil. AB - Water is an essential good for human life. This study aimed to verify the effects of household reservoirs on the physicochemical and microbiological characteristics of water in the municipality of Sao Mateus, Brazil, founded on 21 September 1544. Samples were collected in 83 residences, two samples per residence, one from the supply network and another from the household reservoir, making a total of 166 samples. The pH values, the free residual chlorine content and the turbidity values were determined. For the microbiological analysis, the defined substrate technology was used, allowing the simultaneous detection and identification of total coliforms and Escherichia coli. The results showed that the samples from household reservoirs were more contaminated than those from the public supply network (p = 0.008). The high degree of microbiological contamination of the two groups may be directly associated to the reduced residual chlorine content in the samples, especially those from household reservoirs. PMID- 30296840 TI - Cerebral autoregulation in migraine with aura: A case control study. AB - Background Migraine with aura is independently associated with increased risk of ischemic stroke, especially in younger subjects. This association might be related to an impairment of cerebral autoregulation, which normally maintains cerebral blood flow independent of arterial blood pressure variations. Methods Patients aged 30-55, fulfilling ICHD-3 beta criteria for migraine with aura, were prospectively enrolled and compared with gender- and age-matched healthy controls without a history of migraine. Patients and controls with a history of stroke or any disease potentially impairing cerebral autoregulation were excluded. We assessed cerebral autoregulation with two different methods: Transfer function analysis, and the correlation coefficient index Mx. The transfer function phase and gain reflect responses of cerebral blood flow velocities to relatively fast fluctuations of arterial blood pressure, whereas Mx also reflects responses to slower arterial blood pressure fluctuations. Results A total of 22 migraine with aura patients (median age [IQR]: 39.5 [12.5] years) and 22 controls (39 [9.75] years) were included. Transfer function parameters and Mx were not different between patients and controls. However, Mx was inversely correlated with age in patients (rho = -0.567, p = 0.006) and not in controls (rho = -0.084, p = 0.509). Mx was also inversely correlated with migraine with aura duration (rho = -0.617, p = 0.002), suggesting improvement of cerebral autoregulation efficiency with disease duration. Conclusions Cerebral autoregulation did not differ between patients and controls aged 30-55. However, cerebral autoregulation efficiency was strongly correlated with migraine with aura duration. Further studies in younger patients are needed to determine whether cerebral autoregulation is impaired early in the course of disease. Trial Registration NCT02708797. PMID- 30296841 TI - Improving Patient Experience of Care Providers in a Multispecialty Ambulatory Pediatrics Practice. AB - Patient experience is positively associated with superior medical outcomes, clinical quality, patient safety measures, physician job satisfaction, doctor patient communication, and patient compliance with treatment recommendations. A concrete pediatrics-focused methodology for improving patient experience in a multispecialty ambulatory setting has not been described, nor has the impact on practice outcomes been assessed. The primary aim of this study was to improve patient experience care provider scores at a single multiclinic children's hospital in the Midwest to the 70th percentile in a 5-year period. The secondary aim sought to determine the impact of quality improvement efforts on practice growth, patient complaint rate, and provider/staff engagement. Patient experience was measured by returned Press-Ganey surveys. Interventions involved establishing infrastructure, promoting feedback and transparency, providing education, and transforming culture. Provider scores improved from the 19th to the 70th percentile within 5 years. Practice volume increased by 17.1%; patient complaint/grievance frequency decreased 33-fold; and provider/staff engagement did not appreciably change.

AB - OBJECTIVES:: Tinnitus is an auditory sensation in the absence of any external stimulus. It has a negative impact on quality of life and interferes with concentration, sleep, social activities, and even emotional stability. The aim of this study was to compare sleep architecture in patients with and without chronic subjective tinnitus. METHODS:: This was an observational, noninterventional, and prospective study. The sample consisted of 50 individuals of both sexes aged 20 to 60 years. Twenty-five patients with tinnitus constituted the study group, and for comparison, a control group consisting of 25 patients without reported tinnitus was formed. The patients underwent polysomnography and were administered the Epworth Sleepiness Scale, Tinnitus Handicap Inventory, and visual analog scales. RESULTS:: The group with tinnitus had higher mean values in sleep stages 1 and 2, and lower mean values in stage 3 and in rapid eye movement (REM) sleep, compared with the control group, and this difference was significant only for REM sleep ( P = .031). This demonstrates that patients with tinnitus remained longer in shallow sleep and spent less time in deep sleep (stage 3) and REM sleep. CONCLUSIONS:: This study shows that patients with tinnitus have significant alterations in REM sleep latency as well as the REM sleep phase.

AB - OBJECTIVES:: Dysphagia and impaired saliva control are common in children and adolescents with congenital and developmental disabilities. The aim of the present review was to investigate the evidence base for oral sensory-motor interventions in children and adolescents with dysphagia or impaired saliva control secondary to congenital or early-acquired disabilities and to make recommendations regarding methods for intervention. METHODS:: A review of the literature from 2000 to 2016, including oral sensory-motor intervention studies for children and adolescents (3-18 years of age) with dysphagia or impaired saliva control secondary to congenital or early-acquired disabilities, was performed. The literature search included the PubMed, CINAHL, Medline, SpeechBITE, OVID, ERIC, Cochrane, and Google Scholar databases. Primary studies were evaluated on a 4-grade scale using the Grading of Recommendations Assessment, Development and Evaluation. RESULTS:: Twenty primary studies of oral sensory-motor interventions for dysphagia and 6 studies for the treatment of impaired saliva control fulfilled the inclusion criteria. Of these, 3 were randomized, controlled trials. Five systematic reviews and 16 narrative reviews were also included. Limited and moderately strong recommendations were made on the basis of the grading results from the primary studies. The studies reported good results, but study design was often insufficient, and the study groups were small. The systematic reviews confirmed the lack of high scientific support for oral sensory-motor interventions in children and adolescents with congenital and developmental disabilities. CONCLUSIONS:: There is an urgent need for high quality studies that could serve as the basis for strong recommendations relating to oral sensory-motor interventions for children with dysphagia and impaired saliva control.

We examined the feasibility and preliminary effectiveness of delivering the Group-Early Start Denver Model to children with autism spectrum disorder in inclusive versus specialized classrooms. We randomly assigned 44 preschoolers with autism spectrum disorder to receive the Group-Early Start Denver Model across one school calendar year in classrooms that included only children with autism spectrum disorder or mostly children who were typically developing. Blind-rated indicators of teaching quality showed similar results across settings, which were above the local benchmark. Children showed improvements across blinded proximal measures of spontaneous vocalization, social interaction, and imitation and across distal measures of verbal cognition, adaptive behavior, and autism symptoms irrespective of intervention setting. Mothers of participants experienced a reduction in stress irrespective of child intervention setting. Across both settings, age at intervention start was negatively associated with gains in verbal cognition. Delivery of Group-Early Start Denver Model in an inclusive setting appeared to be feasible, with no significant differences in teaching quality and child improvements when the program was implemented in inclusive versus specialized classrooms. PMID- 30296846 TI - Do the Low WHRs and BMIs Judged Most Attractive Indicate Higher Fertility? AB - We examine the widely accepted view that very low waist-hip ratios and low body mass indices (BMIs) in women in well-nourished populations are judged attractive by men because these features reliably indicate superior fertility. In both subsistence and well-nourished populations, relevant studies of fertility do not support this view. Rather studies indicate lower fertility in women with anthropometric values associated with high attractiveness. Moreover, low maternal BMI predisposes to conditions that compromise infant survival. Consistent with these findings from the literature, new data from a large U.S. sample of women past reproductive age show that women with lower BMIs in the late teens had fewer live births, controlling for education, marital history, and race. They also had later menarche and earlier menopause compared with women with higher youth BMIs. In addition, data from the 2013 U.S. natality database show that mothers with lower prepregnancy BMIs have an increased risk of producing both low-birth-weight and preterm infants controlling for other relevant variables-conditions that would have adversely affected fitness over almost all of human evolution. Thus, a review of the relevant literature and three new tests fail to support the view that highly attractive women are more fertile. PMID- 30296847 TI - Potential benefits of the cognitive orientation to daily occupational performance approach in young adults with spina bifida or cerebral palsy: a feasibility study. AB - PURPOSE: People with cerebral palsy (CP) or spina bifida (SB) often struggle to perform everyday-life activities. Both groups frequently also have difficulties in creating and using strategies effectively when performing tasks. The cognitive orientation to daily occupational performance (CO-OP) Approach combines the learning of cognitive strategies with task-specific approaches through a client centred procedure. The aim of this study was to investigate whether the CO-OP Approach is feasible for and potentially beneficial to adolescents and young adults with CP or SB in Sweden by analysing four areas of feasibility (acceptability, efficacy, adaptation, and expansion). METHODS: Exploratory multiple-case study using mixed methods. Ten persons aged 16-28, five with each condition, participated in an intervention period. Assessments were performed on three occasions: baseline, post-intervention, and six-month follow-up. RESULTS: The result demonstrates that the CO-OP Approach has the potential to enable adolescents and young adults with either condition to achieve personal goals and to enhance their planning skills and their ability to use strategies when performing activities. This approach is also compatible with the core values of habilitation in Sweden and was found by the participants to be highly meaningful and useful. CONCLUSIONS: The CO-OP Approach is feasible for adolescents and young adults with SB or CP in Sweden. Implications for rehabilitation The Cognitive Orientation to daily Occupational Performance * is a feasible approach for adolescents and young adults with spina bifida and with cerebral palsy. * is a promising approach when it comes to enabling the achievement of personal goals. * might have potential to enhance executive functioning through strategy use. * is in line with the fundamental core values of disability rights of inclusion, empowerment, and participation.

AB - BACKGROUND: Although advances in joint-replacement technology have made total ankle arthroplasty a viable treatment for end-stage arthritis, revision rates for ankle replacements are higher than in hip or knee replacements. The questions asked in this study were what can retrieved ankle devices demonstrate about ankle arthroplasty failures and how can understanding the causes of these failures inform clinical decisions for current and future ankle arthroplasty patients? METHODS: An IRB-approved retrieval laboratory received retrieved components and surgeon-supplied reason for revision from 70 total-ankles (7 designs, including 5 currently marketed designs) from 2002 to 2018. These retrievals were rated for clinical wear and damage. Metal components were rated by method and effectiveness of fixation. Polyethylene inserts received by the laboratory 6 months or less after retrieval (n = 45) were analyzed for oxidation using Fourier transform infrared spectroscopy. Statistical analysis was performed using IBM SPSS, version 22. RESULTS: The ankle implants were retrieved most commonly for loosening and polyethylene fracture. Loosening occurred more frequently in fixed-bearing designs (n = 18) than in the mobile-bearing designs (n = 4) and after shorter in vivo time (mean in vivo time to retrieval for loosening: fixed bearing 3.2 +/- 2.1 years, mobile bearing 9.7 +/- 4.5 years). Gamma-sterilized ankle inserts oxidized at a higher rate than non-gamma (EtO or gas-plasma) sterilized ankle inserts (gamma 0.29 +/- 0.22/y, non-gamma 0.07 +/- 0.05/y, mean difference=0.215, 95% CI 0.128-0.303, P < .001). The presence of clinical fatigue (cracking and/or delamination) of the polyethylene insert correlated with measured oxidation (Spearman rho = 0.685, P < .001). Nine inserts, all gamma-sterilized, fractured in vivo. CONCLUSIONS: This study suggests that loosening could be more of a problem in fixed-bearing devices than in mobile bearing devices. Gamma-sterilized polyethylene inserts were found to suffer fatigue damage or fracture in vivo, resulting in the need for revision. Retrieval analysis can provide insight into implant-related reasons for revision, with the goal of understanding the implant related causes of these failures, informing future ankle design and clinical decisions for current and future ankle arthroplasty patients. LEVEL OF EVIDENCE: Level III, comparative series. PMID- 30296849 TI - Do the Low WHRs and BMIs Judged Most Attractive Indicate Better Health? AB - It is widely claimed that in well-nourished populations, very low female waist hip ratios (WHRs) together with low body mass indices (BMIs) are judged attractive by men because these features reliably indicate superior health and fertility. However, studies show that mortality rates are higher in women with low BMIs than in women with average BMIs and are inversely related to BMI in subsistence populations. Measures of current health in women of reproductive age have not been similarly studied. We analyze large U.S. samples of reproductive age women and show that controlling for other factors known to affect health, those with low BMIs (<20), WHRs, or waist/stature ratios did not have better health than those with values in the middle range, and there was no relationship between subsequent health outcomes and BMI in early adulthood. Lower self reported BMIs were linked to poorer health and an increased risk of infection. However, based on recent U.S. natality data, primiparas with lower BMIs had a lower risk of an operative delivery and of gestational hypertension. Beyond these two parity-restricted effects, relevant studies and new tests fail to support the view that women with the very low BMIs and WHRs consistently judged attractive are generally healthier than women with average values; significant correlations were consistently in the opposite direction. PMID- 30296850 TI - Menopausal hormone therapy and breast cancer: what is the evidence from randomized trials? AB - The relationship between menopausal hormone therapy (HT) and breast cancer is complex and further complicated by misinformation, perception, and overgeneralization of data. These issues are addressed in this mini-review through the lens of the Women's Health Initiative (WHI) that has colored the view of HT and breast cancer. In the WHI, unopposed conjugated equine estrogen (CEE) reduced breast cancer risk and mortality. In the WHI CEE plus continuously combined medroxyprogesterone acetate (MPA) trial, although the hazard ratio (HR) was elevated it was statistically non-significant for an association between CEE + MPA and breast cancer. In fact, the increased HR was not due to an increased breast cancer incidence rate in women randomized to CEE + MPA therapy but rather due to a decreased and unexpectedly low breast cancer rate in the subgroup of women with prior HT use randomized to placebo. For women who were HT naive when randomized to the WHI, the breast cancer incidence rate was not affected by CEE + MPA therapy relative to placebo for up to 11 years of follow-up. The current state of science indicates that HT may or may not cause breast cancer but the totality of data neither establish nor refute this possibility. Further, any association that may exist between HT and breast cancer appears to be rare and no greater than other medications commonly used in clinical medicine. PMID- 30296851 TI - Medical Marijuana Laws and Marijuana Use Among U.S. Adolescents: Evidence From Michigan Youth Risk Behavior Surveillance Data. AB - Research findings are inconsistent regarding a positive association between the passage of state medical marijuana laws (MML) and the adolescent access and the use of marijuana. We utilized a novel analytical approach to examine this issue with multiyear data from the 1997-2013 Youth Risk Behavior Surveillance System of the State of Michigan. After controlling for the historically declining trend in marijuana use prior to the passages of MML in Michigan, we found that marijuana use among adolescents had increased subsequent to the passage of state MML. The study findings suggest the need for considering the increased risk of marijuana use in adolescents, as more states have implemented laws permitting marijuana use. PMID- 30296853 TI - The Influence of Latino Symptom Experience on Participation in Usual Activities and Satisfaction With Participation in Social Roles. AB - INTRODUCTION:: Little is known about the Latino symptom experience and how symptoms influence participation in usual activities and satisfaction with participation in social roles. METHOD:: Secondary analysis of survey data collected in community and clinic settings was conducted. Data were collected using Health-Related Quality of Life 30-day items and Patient Reported Outcome Measurement System symptom status scales. Descriptive statistics and univariate linear and multiple linear regression models were computed. RESULTS:: Participants ( N = 2,974) were primarily female and Dominican. Most surveys were completed in Spanish and in the community setting; and the clinic sample had more symptoms. In the multiple linear regression for participation in usual activities, as the number of days with symptoms increased, the number of days that poor physical or mental health influenced participation in usual activities increased. In addition, for satisfaction with participation in social roles, as the number of days with pain and levels of depression and anxiety increased, the levels of satisfaction decreased. Spanish survey administration was associated with decreased levels of satisfaction; and recruitment setting was not a significant predictor. CONCLUSION:: The study addressed multiple knowledge gaps about the Latino symptom experience. PMID- 30296854 TI - Royal jelly does not prevent bone loss but improves bone strength in ovariectomized rats. AB - OBJECTIVE: Royal jelly (RJ) has been used for medical and nutritional purposes, and previous studies have indicated that it may have estrogenic activity. The present study investigated the effects of RJ on bone metabolism in ovariectomized (OVX) rats. METHODS: Rats (12 weeks old) were randomly divided into four groups, namely Baseline, Sham, OVX, and OVX + RJ groups. Rats in the Baseline group were killed immediately, whereas rats in the OVX and OVX + RJ groups underwent bilateral ovariectomy and those in the Sham group underwent sham operation. RJ was administered to rats in the OVX + RJ group daily for 12 weeks. At the end of the 12-week period, bone mass, bone histomorphometry, and bone mechanics were analyzed. RESULTS: Femur bone mineral density (BMD) was significantly lower in the OVX group than in the Sham group, and this decrease in BMD was not ameliorated by RJ administration. However, femur stiffness, as evaluated by a three-point bending test, was significantly higher in the OVX + RJ group than in the OVX group. CONCLUSION: The findings of the present study suggest that RJ does not prevent bone loss, but does improve bone strength in OVX rats. PMID- 30296852 TI - Discovery of novel 1,3-diaryltriazene sulfonamides as carbonic anhydrase I, II, VII, and IX inhibitors. AB - A series of new 1,3-diaryltriazene sulfonamides was synthesised by reaction of diazonium salt of metanilamide (3-aminobenzene sulfonamide) with substituted aromatic amines. The obtained new compounds were assayed as inhibitors of four physiologically and pharmacologically relevant human (h) isoforms of carbonic anhydrases (CA, EC 4.2.1.1), specifically, hCA I, hCA II, and hCA VII (cytosolic isoforms), as well as the tumour-associated membrane-bound isoform hCA IX. All isoforms investigated here were inhibited by the newly synthesised 1,3 diaryltriazene sulfonamide derivatives from the micromolar to the nanomolar range. The cytosolic isoforms were inhibited with Kis in the range of 92.3-8371.1 nM (hCA I), 4.3-9194.0 nM (hCA II), and 15.6-9477.8 nM (hCA VII), respectively. For the membrane-bound tumour-associated isoform hCA IX, the KI-s ranged between 50.8 and 9268.5 nM. The structure-activity relationship (SAR) with these newly synthesised metanilamide derivatives are discussed in detail. PMID- 30296855 TI - Effects of Onchung-eum, an Herbal Prescription, on 5-Fluorouracil-Induced Oral Mucositis. AB - In most cancer patients, chemotherapy-induced oral mucositis (OM) is a frequent side effect, leading to low quality of life and delay in therapy. The aim of this study was to evaluate the effects of Onchung-eum, a well-known herbal prescription in traditional medicine comprising 8 herbs that has long been used for skin diseases, on 5-fluorouracil (5-FU)-induced OM in human pharyngeal cells and golden Syrian hamsters. DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay, and reactive oxygen species production were measured in vitro. The effects of Onchung-eum on OM of hamster cheek pouches induced by 5-FU were evaluated histologically and using TUNEL assay. In addition, the expression of nuclear factor-kappaB, caspase-3, and pro-inflammatory cytokines were measured by immunoblotting and immunohistochemistry. Significantly increased cell viability was observed in the Onchung-eum-treated groups compared with the 5-FU-treated control group. In 500 and 1000 mg/kg Onchung-eum-treated groups, the damaged epithelial layers in the cheek pouches of hamsters were significantly recovered. Moreover, at all concentrations, cell death in the cheek pouches of hamsters in the Onchung-eum-treated groups significantly decreased. The expression of pro inflammatory cytokines, nuclear factor-kappaB, and caspase-3 also significantly decreased in Onchung-eum-treated groups at 500 and 1000 mg/kg. In conclusion, this study revealed that Onchung-eum can be used to treat chemotherapy-induced OM. However, further studies are required to understand the underlying mechanisms. PMID- 30296856 TI - The Swedish motor neuron disease quality registry. AB - OBJECTIVE: We set up the Swedish Motor Neuron Disease (MND) Quality Registry to assure early diagnosis and high-quality health care for all MND patients (mainly amyotrophic lateral sclerosis, ALS), and to create a research base by prospectively following the entire MND population in Sweden. METHODS: Since 2015, the MND Quality Registry continuously collects information about a wide range of clinical measures, biological samples, and quality of life outcomes from all MND patients recruited at the time of MND diagnosis in Sweden and followed at each clinic visit approximately every 12 weeks. The Registry includes an Internet based patient own reporting portal that involves patients in the registration of their current symptoms and health status. RESULTS: As of 20th January 2017, the MND Quality Registry included 99% of the MND patients of the Stockholm area (N = 194), consisting mostly of ALS patients (N = 153, 78.9%), followed by patients labeled as MND due to a neurophysiology finding but not fulfilling the criteria for ALS (N = 20, 10.3%), primary lateral sclerosis (N = 13, 6.7%), and progressive spinal muscular atrophy patients (N = 8, 4.1%). A higher proportion of these patients were women (N = 100, 52%), and women and men had a similar age at symptoms onset (59 years). CONCLUSIONS: Main strengths of the MND Quality Registry are its clinical, quantitative, qualitative, and prospective nature, providing the researchers potential means of identifying appropriate candidates for clinical trials and other research projects, as well as assuring to the patients an effective and adequate time spent on-site with the healthcare professionals. PMID- 30296857 TI - Between medicalisation and normalisation: Antithetical representations of depression in the Greek-Cypriot press in times of financial crisis. AB - Media offer people ways of understanding mental health and illness, shaping their attitudes and behaviour towards it. Yet, the literature on media representations of depression is limited and fails to illuminate sufficiently the content of representations. In times of financial crisis, the prevalence of depression is increased and the particular meanings associated with depression are widely diffused. To unpack these meanings, we focused on the Greek-Cypriot press during the financial crisis of 2013. Two-hundred and three articles from seven widely circulating newspapers were thematically analysed. Two antithetical themes of representations of depression were identified: Biomedical Depression, which constructed depression as a biologically grounded illness treated through medical/pharmaceutical means, and Everyday Depression, which portrayed depression as something normal, encountered in anyone, attributed to psychosocial factors (e.g. the financial crisis), and treated through self-management. Biomedical Depression reflects a widespread medical and deterministic understanding of depression. Nevertheless, this understanding has not overridden, as the literature suggests, references to individual agency, which are present in the Everyday Depression and the more normalising understanding of depression it expresses. We argue, however, that both themes promote an individualistic understanding of depression, placing individuals in a tense position of being responsible for a condition perceived to be outside their control. PMID- 30296858 TI - Movement and Demography of At-Risk Butterflies: Building Blocks for Conservation. AB - The number of insect species at risk of population decline and extinction is increasing rapidly. Yet we know almost nothing about the ecology of these species, except for at-risk butterflies. A growing body of literature shows how butterfly vital rates, including demography and movement, are essential for guiding conservation and recovery. History has shown us that without these data, conservation decisions often weaken, rather than enhance, population viability. This is especially true in changing landscapes. We review knowledge of vital rates across all at-risk butterflies. We have information on movement for 17 of 283 butterfly species and information on demography for 19 species. We find that habitat-specific movement behavior is key to understanding how to connect populations, and habitat-specific demography is central to managing habitats. Methods and analyses worked out for butterflies can provide a scaffold around which to build studies for the conservation of other at-risk insects.

PMID- 30296859 TI - Movement Ecology of Pest Helicoverpa: Implications for Ongoing Spread. AB - The recent introduction and spread of Helicoverpa armigera throughout South America highlights the invasiveness and adaptability of moths in the Helicoverpa genus. Long-range movement in three key members, H. armigera, H. zea, and H. punctigera, occurs by migration and international trade. These movements facilitate high population admixture and genetic diversity, with important economic, biosecurity, and control implications in today's agricultural landscape. This is particularly true for the spread of resistance alleles to transgenic crops expressing Bacillus thuringiensis (Bt) toxins that are planted over vast areas to suppress Helicoverpa spp. The ability to track long-distance movement through radar technology, population genetic markers, and/or long distance dispersal modeling has advanced in recent years, yet we still know relatively little about the population trajectories or migratory routes in Helicoverpa spp. Here, we consider how experimental and theoretical approaches can be integrated to fill key knowledge gaps and assist management practices. Expected final online publication date for the Annual Review of Entomology Volume 64 is January 7, 2019. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates. PMID- 30296860 TI - Proof of concept studies for siRNA delivery by non-ionic surfactant vesicles: in vitro and in vivo evaluation of protein knockdown. AB - RNA interference (RNAi) is an effective and naturally occurring post transcriptional gene regulatory mechanism. This mechanism involves the degradation of a target messenger RNA (mRNA) through the introduction of short interfering RNA (siRNA) that is complementary to the target mRNA. The application of siRNA-based therapeutics is limited by the development of an effective delivery system, as naked siRNA is unstable and cannot penetrate the cell membrane. In this study, we investigated the use of cationic niosomes (CN) prepared by microfluidic mixing for siRNA delivery. In an in vitro model, these vesicles were able to deliver anti-luciferase siRNA and effectively suppress luciferase expression in B16-F10 mouse melanoma cells. More importantly, in an in vivo mouse model, intratumoral administration of CN-carrying anti-luciferase siRNA led to significant suppression of luciferase expression compared with naked siRNA. Thus, we have established a novel and effective system for the delivery of siRNA both in vitro and in vivo, which shows high potential for future application of gene therapeutics. PMID- 30296861 TI - Psychosocial consequences among women with false-positive results after mammography screening in Norway. AB - BACKGROUND: Mammography screening may cause psychosocial harm for women experiencing a false-positive screening result. Previous studies suggest long term consequences. The aim of the present study was to assess psychosocial consequences of false-positive findings on screening mammography within a six month follow-up. METHODS: A prospective matched cohort survey study using the questionnaire 'Consequences of Screening for Breast Cancer' (COS-BC), which was translated from Danish to Norwegian. Psychometric analyses investigated the measurement properties of the Norwegian version. Two screening clinics in Norway distributed the survey to 299 women with an abnormal mammogram and 541 women with a normal screen. Women received the questionnaire when receiving the screening result, and one and six months after screening. RESULTS: At six months, statistically significant differences appeared in two scales: existential values and breast examination. At six-month follow-up, women with false-positive results showed no statistically significant differences from women diagnosed with breast cancer in three outcomes: sense of dejection, anxiety, and keeping my mind off things. CONCLUSION: Our results indicate that the psychosocial consequences from having false-positive screening mammography results diminish after six months. The results support previous research describing breast-specific outcomes. However, our results indicate that Norwegian women are less frightened than other Scandinavian mammography screening participants. PMID- 30296862 TI - Porphyrias and photosensitivity: pathophysiology for the clinician. AB - Porphyrias are disorders caused by defects in the biosynthetic pathway of heme. Their manifestations can be divided into three distinct syndromes, each attributable to the accumulation of three distinct classes of molecules. The acute neurovisceral syndrome is caused by the accumulation of the neurotoxic porphyrin precursors, delta aminolevulinic acid, and porphobilinogen; the syndrome of immediate painful photosensitivity is caused by the lipid-soluble protoporphyrin IX and, the syndrome of delayed blistering photosensitivity, caused by the water-soluble porphyrins, uroporphyrin, and coproporphyrin. Porphyrias can manifest with one, or with a combination, of these syndromes, depending on whether one or more types of molecules are being accumulated. Iron plays a significant role in some of these conditions, as evidenced by improvements in both clinical manifestations and laboratory parameters, following iron depletion in porphyria cutanea tarda, or iron administration in some cases of X-linked erythropoietic protoporphyria. While the pathophysiology of a specific type of porphyrias, the protoporphyrias, appears to favor the administration of zinc, results so far have been conflicting, necessitating further studies in order to assess its potential benefit. The pathways involved in each disease, as well as insights into their pathobiological processes are presented, with an emphasis on the development of photosensitivity reactions.

PMID- 30296863 TI - Lung delivery of nanoliposomal salbutamol sulphate dry powder inhalation for facilitated asthma therapy. AB - The motive behind present work was to discover a solution for overcoming the problems allied with deprived oral bioavailability of salbutamol sulphate (SS) due to its first pass hepatic metabolism, shorter half life and systemic toxicity at high doses. Pulmonary delivery provides alternative route of administration to avoid hepatic metabolism of SS, moreover facilitated diffusion and prolonged retention can be achieved by incorporation into liposomes. Liposomes were prepared by thin film hydration technique using 32 full factorial design and formulation was optimized based on the vesicle size and percent drug entrapment (PDE) of liposomes. Optimized liposomal formulation exhibited average size of about 167.2+/-0.170 nm, with 80.68+/-0.74% drug entrapment, and 9.74+/-1.10 mV zeta potential. The liposomal dispersion was then spray dried and further characterized for in-vitro aerosol performance using Andersen Cascade Impactor. Optimized liposomal formulation revealed prolonged in-vitro drug release of more than 90% up to 14 h following Higuchi's controlled release model. Thus, proposed new-fangled liposomal formulation would be a propitious alternative to conventional therapy for efficient and methodical treatment of asthma and alike respiratory ailments. PMID- 30296865 TI - Novel abdominal approach for dissection of advanced type II/III adenocarcinoma of the esophagogastric junction: a new surgical option. AB - Objective The optimal surgical approach for Siewert type II adenocarcinoma of the esophagogastric junction (AEG) is controversial. In this study, we evaluated the outcomes of total gastrectomy for Siewert type II/III AEG via the left thoracic surgical approach that is used at our center. Methods We identified 41 patients with advanced AEG in our retrospective database and analyzed their 3-year survival rate, upper surgical margin, postoperative complications, and index of estimated benefit from lymph node dissection. Results The 3-year overall survival rate of the whole group was 63%, but no difference was observed between Siewert type II and III AEGs. Esophageal exposure and lymphadenectomy were sufficient. Eight patients developed postoperative complications, but none of the patients developed anastomotic leakage. Dissection of lymph node station Nos. 19 and 110 may be necessary for patients with Siewert type II AEG. Multivariate analysis revealed that the cT category was the only independent risk factor. Conclusions Total gastrectomy via an approach from the abdominal cavity into the thoracic cavity may be an optimal surgical technique for advanced Siewert type II AEG. PMID- 30296866 TI - Mental adjustment to cancer and quality of life among women living with breast cancer in Ghana. AB - Objective This study examined whether cancer-specific coping strategies have any significant influence on the quality of life of 205 women living with breast cancer in Ghana. Methods Using a cross-sectional survey design, participants were administered questionnaires which measured their cancer-specific coping strategies and health-related quality of life. Results Correlation analysis showed that helplessness-hopelessness negatively correlated with physical wellbeing, emotional wellbeing, functional wellbeing, and breast cancer additional concerns. Anxious preoccupation negatively correlated with all the domains of quality of life, whereas fighting spirit was positively correlated with emotional and functional wellbeing. Cognitive avoidance was positively correlated with functional wellbeing, while fatalism was positively related with all the domains of quality of life. Regression analysis revealed that anxious preoccupation predicted significant decreases in all the domains of quality of life, while helplessness-hopelessness predicted significant decreases in emotional and functional wellbeing domains. However, cognitive avoidance predicted significant increase in the functional domain of quality of life. Conclusion These findings underscore the need for psychosocial support for breast cancer patients to adopt effective coping strategies to deal with their challenges in managing their illness. PMID- 30296867 TI - Delayed intranasal coil extrusion after internal carotid artery pseudoaneurysm embolization. AB - Internal carotid artery (ICA) injury is a rare but potentially life-threatening complication of skull base and neck surgery. Although usually manifested by massive intraoperative haemorrhage, impairment of the ICA might go unnoticed and result in formation of a pseudoaneurysm, causing delayed bleeding. Often additional complications are observed such as thrombosis, spasm, embolism or carotico-cavernous fistula formation. The risk of carotid artery injury in aggressive endonasal skull base surgical interventions ranges from 1% to 9%. Digital subtracted angiography remains the gold standard for evaluation of patients with iatrogenic carotid artery injury as it allows for endovascular treatment at the time of the procedure. Endovascular embolization is currently the preferred method for treating ICA pseudoaneurysms and a successful alternative to the surgical approach. Even though endovascular approaches are considered the safer option, delayed complications have been registered, such as endovascular coil extrusion and migration, which increases the risk of further episodes of bleeding. We present our experience with late coil extrusion in a patient who was previously treated with flow diverter stent and coiling for iatrogenic ICA pseudoaneurysm. PMID- 30296869 TI - Perceptions of Needs, Assets, and Priorities Among Black Men Who Have Sex With Men With HIV: Community-Driven Actions and Impacts of a Participatory Photovoice Process. AB - Black men who have sex with men (MSM) with HIV experience significant health inequities and poorer health outcomes compared with other persons with HIV. The primary aims of this study were to describe the needs, assets, and priorities of Black MSM with HIV who live in the Southern United States and identify actions to improve their health using photovoice. Photovoice, a participatory, collaborative research methodology that combines documentary photography with group discussion, was conducted with six Black MSM with HIV. From the photographs and discussions, primary themes of discrimination and rejection, lack of mental health services, coping strategies to reduce stress, sources of acceptance and support, and future aspirations emerged. After the photographs were taken and discussed, the participants hosted a photo exhibition and community forum for the public. Here, 37 community attendees and influential advocates collaborated with the participants to identify 12 actions to address the men's identified needs, assets, and priorities. These included making structural changes in the legal and medical systems, encouraging dialogue to eliminate multiple forms of stigma and racism, and advocating for comprehensive care for persons with HIV. As a secondary aim, the impacts of photovoice were assessed. Participants reported enjoying photovoice and found it meaningful. Results suggest that in addition to cultivating rich community-based knowledge, photovoice may result in positive changes for Black MSM with HIV. PMID- 30296868 TI - Mesenchymal stromal cells in the treatment of perianal fistulas in Crohn's disease. AB - Significant unmet needs remain in patients with Crohn's disease and perianal fistulas. Mesenchymal stromal cells have potent immunomodulatory actions. The Phase II studies reported efficacy of local injection of mesenchymal stromal cells to achieve closure of fistulas. A Phase III trial demonstrated that in patients with Crohn's disease and refractory complex perianal fistulas, a single injection of 120 * 106 cells was superior to local injection of placebo associated with the same surgical procedure, in obtaining closure of the fistula tracts together with absence of abscesses >2 cm, 24 weeks after the injection, a stringent combined primary end point. The benefit over placebo was sustained 52 weeks after the single injection. The therapy is safe with adverse events limited to local pain. PMID- 30296870 TI - Andexanet alfa for the treatment of hemorrhage. AB - INTRODUCTION: While associated life-threatening and fatal bleeding events are less frequent with the direct factor Xa inhibitors compared to vitamin K antagonists, significant concern surrounding management of major bleeds and urgent periprocedural interruption of these agents exists among clinicians. Andexanet alfa is a recombinant human factor Xa decoy protein developed in response to this clinical gap in the care of patients receiving anticoagulation with factor Xa inhibitors. Areas covered: This paper reviews results from preclinical and healthy-volunteer studies demonstrating the ability of andexanet to rapidly and reliably normalize coagulation indices in patients treated with both direct and indirect factor Xa inhibitors. An interim analysis from an ongoing phase 3/4b clinical study assessing the efficacy and safety of andexanet in patients experiencing life-threatening hemorrhage in association with factor Xa inhibitors is discussed. It also provides an overview of the major safety concerns reported in these trials which include allergic and infusion reactions, development of anti-andexanet antibodies and, importantly, thrombosis. Expert commentary: While initial reports on restoration of hemostasis and safety are promising, further study of andexanet is required to gauge its efficacy and toxicity, including a potential prothrombotic effect. Further, its use in patients requiring urgent surgery should be studied. PMID- 30296871 TI - Trends in primeval beta-hCG level increment after fresh and frozen-thawed IVF embryo transfer cycles. AB - Mid-trimester beta-human chorionic gonadotropin (BHCG) levels are considerably higher in pregnancies resulting from frozen embryo transfer (FET) compared with fresh (FRET), leading to a higher false positive rate in aneuploidy screening tests. We aimed to investigate the dynamics of BHCG increment and its predictive value for cycle outcome. A retrospective analysis of FRET and FET cycles. BHCG values on days 14 and 16 post embryo transfer were compared and stratified according to the number of sacs demonstrated on US scan at six weeks gestation, and pregnancy outcome (biochemical pregnancy, ectopic pregnancy, spontaneous abortion, and a singleton or twin birth). A prediction model for live birth was built. A total of 430 treatment cycles were analyzed. The average BHCG levels were significantly higher in FET compared with FRET group in nonviable pregnancies on day 14, 450 vs. 183 IU/L, p < .05 and day 16, 348 vs. 735 IU/L, p < .05, respectively. The increment of BHCG was significantly steeper in the FET compared with FRET group in biochemical pregnancies (F = 6.485, p = .012*). Optimal cutoff level for live birth prediction in the FRET group was 211 IU/L (sensitivity 84%, specificity 76.2%) for day 14 and 440 IU/L (sensitivity 86.0% and specificity 72.5%) for day 16. The increment in BHCG differed significantly between the FRET and FET cycles in nonviable pregnancies. Nevertheless, the difference in BHCG levels observed in the second trimester in pregnancies conceived after FRET and FET cycle may begin as early as the fourth week of pregnancy. PMID- 30296872 TI - Analysis of selected promoter polymorphisms and haplotypes of the CYBA gene encoding the p22phox, subunit of NADPH oxidases, in patients with coronary artery disease. AB - BACKGROUND: The p22phox is a critical component of vascular NADPH oxidases and is encoded by the CYBA gene. It was shown that functionally relevant polymorphisms of the CYBA gene - 930A>G, -852C>G , -675A>T , -536C>T, 214C>T (previously described as 242C>T), *24A>G (previously described as 640A>G), and *49A>G modulate generation of reactive oxygen species (ROS). AIM: Analyse whether the CYBA gene polymorphisms - 852C>G, -675A>T , and - 536C>T were associated with coronary artery disease (CAD), and to designate haplotype blocks. METHODS: Four hundred and ninety subjects: 245 patients with CAD and 245 age and sex matched controls. The polymorphisms were genotyped using the PCR-RFLP method and the TagMan(r) Pre-designed SNP Genotyping Assay. RESULTS: The analysed polymorphisms do not form haplotype blocks. Case-control study revealed that the -930 G/-675T and -930G /*49G diplotypes were a CAD risk factor. The 675T/*49G diplotype can modulate CAD risk in women. The protective effect reducing CAD risk in women was related to the -930A/-675T and -930A /*49A diplotypes. Carrier state of the -852C allele ( -852C>G ) was associated with multivessel stenosis while the CC genotype of the -536C>T polymorphism was more frequent in patients with peripheral artery disease. Hypercholesterolemic, cigarette smokers had an increased risk of CAD, especially C - 852 allele (-852C>G) carriers (SIM = 3.54; odds ratios (OR) = 10.01, p < 0.000). CONCLUSIONS: The CYBA gene polymorphisms modulate the risk of CAD but do not form a haplotype blocks. PMID- 30296873 TI - Association between serum copper levels and lung cancer risk: A meta-analysis. AB - Objective To evaluate the association between serum copper levels and lung cancer risk. Methods We searched the electronic PubMed, WanFang, CNKI, and SinoMed databases to identify studies including information on serum copper levels and lung cancer. Standard mean differences and corresponding 95% confidence intervals were calculated using Stata 12.0 software. We performed a meta-analysis on the identified studies overall and according to geographic location. We also evaluated heterogeneity among the studies and the occurrence of publication bias. Results Thirty-three articles including 3026 cases and 9439 controls were included in our study. The combined results showed that serum copper levels were higher in patients with lung cancer compared with controls without lung cancer, though the results showed high heterogeneity. In a subgroup analysis according to geographic location, significant associations between copper levels and lung cancer were found for both Asian and European populations. No publication bias was detected in this meta-analysis. Conclusions High serum copper levels could increase the risk of lung cancer, suggesting that environmental copper exposure may be a risk factor for the development of lung cancer. PMID- 30296874 TI - Sleep problems and mental health among young Norwegian adolescents. AB - PURPOSE: The present study investigated the associations between the aspects of sleep problems and mental health in Norwegian young adolescents. MATERIALS AND METHODS: Adolescents (12-13 years) were recruited from the primary schools in Telemark County, Norway. Sleep related problems were assessed by asking parents three questions related to their childrens' sleep quality, sleep sufficiency, and daytime sleepiness. Parents reported data on mental health by the extended version of the Strengths and Difficulties Questionnaire (SDQ), and information on the child's physical activity, screen time, eating pattern, gender, and background variables. Height and weight were objectively measured. Complete data were obtained for 690 adolescents. RESULTS: Multiple logistic regressions were used. Bivariate analyses indicated important associations between the sleep aspects and mental health. When adjusting the sleep variables for each other, lifestyle factors and background variables, sleep quality problems were associated with any psychiatric problem (ORadj: 4.0, CI: 2.0-8.2), emotional problems (ORadj: 15.1, CI: 3.4-66.8), and hyperactivity-inattention problems (ORadj: 5.1, CI: 2.2-12.1). Daytime sleepiness problems were associated with any psychiatric problem (ORadj: 2.3, CI: 1.2-4.4), and hyperactivity-inattention problems (ORadj: 2.5, CI: 1.1-5.5). Bivariate associations between problems with sufficient sleep and mental health problems lost the significance when adjusted for other sleep variables. CONCLUSIONS: The results indicate that different aspects of sleep problems may be important underlying factors for mental health problems in adolescents, independently of lifestyle factors, BMI-category, gender, and background variables. This highlights the importance of examining specific sleep problems when investigating associations between sleep and mental health. PMID- 30296875 TI - Improved Medication Management With Introduction of a Perioperative and Prescribing Pharmacist Service. AB - BACKGROUND: The medication lists in pre-admission clinic (PAC) questionnaires completed by patients prior to surgery are often inaccurate, potentially leading to medication errors during hospitalization. Studies have shown pharmacists are more accurate when obtaining a medication history and transcribing prescription orders, thereby reducing errors. OBJECTIVE: To evaluate the impact of a PeRiopErative and Prescribing (PREP) pharmacist on postoperative medication management. METHODS: A randomized prospective interventional study enrolled elective surgery patients at high risk for medication misadventure to receive PREP pharmacy service or usual care (control group). A best possible medication history (BPMH) was obtained by the PREP pharmacist and was available to surgical staff on admission. The PREP pharmacist also prepared discharge prescriptions for their patients. The primary outcomes for the study were accuracy of BPMH and discharge prescriptions compared to usual care. The study was powered to 80% with 2-tailed significance alpha of .05. RESULTS: The medication history in the PREP pharmacist group had fewer errors than the control group: 9% (5/53) versus 96% (49/51; P < .001). Discharge prescriptions prepared by the PREP pharmacist had fewer errors than control group: 25% versus 78% ( P < .001). Significantly, more PREP pharmacist patients received a discharge summary with a complete medication list: 75% versus 33% ( P = .001). Inpatient prescribing was more accurate in the PREP pharmacist patients: 0.64 versus 1.31 errors per patient ( P = .047). CONCLUSION: Inclusion of the PREP pharmacist role in the elective surgery multidisciplinary team improved the accuracy of medication histories, inpatient prescribing, and discharge prescriptions for patients at high risk of medication misadventure. PMID- 30296876 TI - Can certain factors for recurrence of placenta-mediated pregnancy complications be identified after an initial small-for-gestational-age birth? AB - OBJECTIVES: After a small-for-gestational-age (SGA) birth, recurrence of placenta mediated pregnancy complications (PMPCs) is a cause for anxiety when contemplating another pregnancy. We sought to identify factors potentially associated with this recurrence. STUDY DESIGN: This retrospective single-center observational study was conducted in a tertiary maternity unit between 1 January, 2010 and 31 December, 2017. We included all women having experienced a non syndromic SGA birth and who were subsequently monitored for at least one other pregnancy in our institution. PMPCs were defined as recurrent SGA births, three consecutive first-trimester miscarriages, or preeclampsia. RESULTS: Ninety-four women were included over a 7-year study period. Recurrent PMPCs were recorded in 30 (32%) cases, of which 29 featured recurrent SGA births. None of the following characteristics were significantly associated with recurrence: presence of preeclampsia during the initial pregnancy (six [20%] versus 25 [39%] cases in the recurrent PMPCs and nonrecurrent PMPCs groups respectively; p = 0.11), results of the histopathologic placental examination or thrombophilia screen (positive in 5 [17%] cases versus 17 [27%] respectively; p = 0.27), or implemented treatment during subsequent pregnancies. CONCLUSIONS: PMPCs recur frequently. No risk factor for recurrence was identified in our study. Results of etiologic assessments and treatments implemented after an initial SGA birth should therefore not modify level of clinical and ultrasound monitoring provided during subsequent pregnancies. PMID- 30296877 TI - Teaching sociology to undergraduate medical students. AB - Understanding the social basis of health and medicine and the contexts of clinical care are essential components of good medical practice. This includes the ways in which social factors such as class, ethnicity, and gender influence health outcomes and how people experience health, illness, and health care. In our Guide we describe what sociology is and what it brings to medicine, beginning with the nature of the "sociological imagination." Sociological theory and methods are reviewed to explain and illustrate the role of sociology in the context of undergraduate medical education. Reference is made to the 2016 report, A Core Curriculum for Sociology in UK Undergraduate Medical Education by Collett et al. Teaching and student learning are discussed in terms of organization and delivery, with an emphasis on practice. Sections are also included on assessment, evaluation, opportunities, and challenges and the value of a "community of practice" for sociology teachers in medical education. PMID- 30296878 TI - Treatment, transport, and primary care involvement when helicopter emergency medical services are inaccessible: a retrospective study. AB - OBJECTIVE: To examine handling of cancelled helicopter emergency medical services (HEMS) missions with a persisting medical indication. DESIGN: Retrospective observational study. SETTING AND SUBJECTS: Cancelled HEMS missions with persisting medical indication within Sogn og Fjordane county in Norway during the period of 2010-2013. Both primary and secondary missions were included. MAIN OUTCOME MEASURES: Primary care involvement, treatment and cooperation within the prehospital system. RESULTS: Our analysis included 172 missions with 180 patients. Two-thirds of the patients (118/180) were from primary missions. In 95% (112/118) of primary missions, GPs were alerted, and they examined 62% (70/112) of these patients. Among the patients examined by a GP, 30% (21/70) were accompanied by a GP during transport to hospital. GP involvement did not differ according to time of day (p = 0.601), diagnostic group (p = 0.309), or patient's age (p = 0.409). In 41% of primary missions, the patients received no treatment or oxygen only during transport. Among the secondary missions, 10% (6/62) of patients were intubated or received non-invasive ventilation and were accompanied by a physician or nurse anaesthetist during transport. CONCLUSIONS: Ambulance workers and GPs have an important role when HEMS is unavailable. Our findings indicated good collaboration among the prehospital personnel. Many of the patients were provided minimal or no treatment, and treatment did not differ according to GP involvement. Key Points Knowledge about handling and involvement of prehospital services in cancelled helicopter emergency medical services (HEMS) missions are scarce. Ambulance workers and general practitioners have an important role when HEMS is unavailable Minimal or no treatment was given to a large amount of the patients, regardless of which health personnel who encountered the patient. PMID- 30296879 TI - Media Use, Sleep Quality, and ADHD Symptoms in a Community Sample and a Sample of ADHD Patients Aged 8 to 18 Years. AB - OBJECTIVE: Relationships between sleep, screen-based media, and ADHD symptomatology were investigated using a case- and community-based approach. METHOD: N = 357 healthy and N = 61 children with ADHD (12.72 +/- 2.83 years) completed a sleep and media questionnaire. To measure ADHD symptomatology, parents filled out the Strengths and Weaknesses of ADHD symptoms and Normal behavior (SWAN) scale. Two samples were formed: a matched ( N = 61 patients and N = 61 controls) and a community sample ( N = 357 healthy participants and N = 20 patients). RESULTS: Compared with controls, participants with ADHD reported delayed sleep onset and more screen time on school days. Adolescent patients showed more behavior promoting delayed sleep phase. In the community sample, media time, sleep deviation, and circadian rhythm were correlated with ADHD symptomatology. Furthermore, media time, sleep-wake behavior, and sleep deviation were predictive of ADHD symptomatology (variance explained = 4%-15%). CONCLUSION: Longer media time and inadequate sleep-wake behavior increase the risk of ADHD like symptoms. However, research using objective assessments is needed to disentangle this distinct association and to provide possible directions for intervention. PMID- 30296881 TI - Temperament and Cognitive Regulation During the First 3 Years of Life as Predictors of Inattention and Hyperactivity/Impulsivity at 6 Years. AB - OBJECTIVE: With a wish to identify early markers of inattention and hyperactivity/impulsivity, we examined effects of temperament and cognitive regulation, during the first 3 years of life, on later inattentive and hyperactive/impulsive behavior. METHOD: Temperament and cognitive regulation were assessed at 12, 18, 24, and 36 months in 66 typically developing children. Teachers rated inattention and hyperactivity/impulsivity at 6 years. RESULTS: Temperamental activity at all studied time points was predictive of later hyperactive/impulsive behavior, thus appearing as a stable marker thereof. Activity at 12 months was also predictive of inattention, whereas temperamental persistence was correlated with inattention and hyperactivity/impulsivity, but with no independent contributions. No significant relations between cognitive regulation and the outcome measures were found. CONCLUSION: Our findings add to the scarce literature proposing that markers of inattentive and hyperactive/impulsive behavior in early school age can be found within the first years of life, using parental ratings of child temperament. PMID- 30296880 TI - Effects of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers on cardiovascular events in patients with diabetes and overt nephropathy: a meta-analysis of randomised controlled trials. AB - OBJECTIVE: The efficacy of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in reducing cardiovascular outcomes in patients with diabetes and overt nephropathy is still a controversial issue. METHODS: We systematically searched MEDLINE, Embase and Cochrane Library for randomised controlled trials. RESULTS: Thirteen trials containing 4638 patients with diabetes and overt nephropathy were included. Compared with controls, angiotensin converting enzyme inhibitor/angiotensin receptor blocker treatment did not reduce the risk of cardiovascular events (odds ratio 0.94, 95% confidence interval 0.86 to 1.03, P=0.18; I2=0.0%, P=0.75). Angiotensin-converting enzyme inhibitor/angiotensin receptor blocker therapy reduced the odds of heart failure events by 29% (0.71, 0.61 to 0.83, P<0.001; I2=0%, P=0.78). The results indicated no significant differences between the two treatment regimens with regard to the frequency of MI (0.95, 0.76 to 1.19, P=0.64), stroke (1.20, 0.83 to 1.74, P=0.32), cardiovascular death (1.26, 0.96 to 1.65, P=0.09) and all-cause mortality (0.98, 0.86 to 1.12, P=0.73). Among all kinds of adverse effects, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker therapy increased the incidence of hyperkalemia (2.26, 1.42 to 3.61, P=0.001). CONCLUSION: This study demonstrated that angiotensin-converting enzyme inhibitors and angiotensin receptor blockers did not reduce cardiovascular events in patients with diabetes and overt nephropathy. PMID- 30296882 TI - Healthy Volunteers' Perceptions of the Benefits of Their Participation in Phase I Clinical Trials. AB - Other than the financial motivations for enrolling in Phase I trials, research on how healthy volunteers perceive the benefits of their trial participation is scant. Using qualitative interviews conducted with 178 U.S. healthy volunteers enrolled in Phase I trials, we investigated how participants described the benefits of their study involvement, including, but not limited to, the financial compensation, and we analyzed how these perceptions varied based on participants' sociodemographic characteristics and clinical trial history. We found that participants detailed economic, societal, and noneconomic personal benefits. We also found differences in participants' perceived benefits based on gender, age, ethnicity, educational attainment, employment status, and number of clinical trials completed. Our study indicates that many healthy volunteers believe they gain more than just the financial compensation when they accept the risks of Phase I participation. PMID- 30296883 TI - The Relationship Between Executive Function Deficits and DSM-5-Defined ADHD Symptoms. AB - OBJECTIVES: To identify the relationship between the core Diagnostic and Statistical Manual of Mental Disorders (5th ed.) ADHD symptoms and executive function deficits (EFDs), to evaluate ADHD characteristics of those with executive dysfunction (ED), and to examine the predictive utility of the Adult ADHD Investigator Symptom Rating Scale (AISRS) in identifying those with adult ADHD and ED. METHOD: Two samples (referred and primary care practice) were pooled together for present analysis. RESULTS: Final analysis included 297 respondents, 171 with adult ADHD. Spearman correlation coefficients and binary logistic regressions demonstrated that ADHD inattentive (IA) and hyperactive-impulsive (H I) symptoms were moderately to strongly correlated with and highly predictive of EFDs. Receiver operating characteristic curve analysis showed that an AISRS DSM 18-item score of ? 28 was most predictive of clinical ED. CONCLUSION: ADHD symptoms were strongly correlated with and predictive of EFDs, clinicians should screen adults with ADHD for EFDs and ADHD treatment providers should track EFD improvement in addition to DSM-5 ADHD symptoms. PMID- 30296884 TI - Measuring the Quality and Performance of Institutional Review Boards. AB - Despite the importance of institutional review boards (IRBs) in protecting human subjects participating in research and the well-known benefits of performance measurements, there has been no systematic assessment of the quality and performance of IRBs. The IRB community has frequently cited the lack of credible metrics for measuring human subject protections and the quality of IRB ethics reviews as reasons for not measuring the quality and performance of IRBs. However, the IRB, with its well-defined missions, functions, structure, and procedures, should be readily amendable to performance measurements. In this brief commentary, I analyzed potential barriers for measuring the quality of IRBs and proposed ways to overcome these barriers. PMID- 30296885 TI - Quality assessment in general practice: diagnosis and antibiotic treatment of acute respiratory tract infections. AB - OBJECTIVE: To investigate areas in need of quality improvement within the diagnostic process and antibiotic treatment of acute respiratory tract infections (RTIs) in Danish general practice by using quality indicators (QIs). DESIGN AND SETTING: During a 4-week period in winter 2017, a prospective registration of patients diagnosed with RTIs was conducted in general practice in two regions of Denmark. SUBJECTS: Throughout the registration period each patient with symptoms of an RTI was registered. Information about age, symptoms and findings, duration of symptoms, the use and result of clinical tests, allergy towards penicillin, referral to secondary care and the antibiotic given were recorded. MAIN OUTCOME MEASURES: Values and acceptable ranges for QIs focusing on the diagnostic process, the decision to prescribe antibiotics and the choice of antibiotics for patients with RTIs. RESULTS: Regarding the diagnostic process nearly all QIs for patients diagnosed with acute pharyngotonsillitis and pneumonia fell within the acceptable range. Contrarily, the diagnostic QIs for patients with acute otitis media and acute rhinosinusitis were outside the acceptable range. All indicators designed to measure overuse of antibiotics were outside the acceptable range and nearly all indicators assessing if patients were sufficiently treated fell within the acceptable range. QIs assessing use of the recommended type of antibiotic were only within the acceptable range for patients diagnosed with acute pharyngotonsillitis. CONCLUSION: The findings indicate an overuse of antibiotics for RTIs in Danish general practice. Especially management of acute rhinosinusitis and acute bronchitis should be targeted in future quality improvement projects. KEY POINTS: To improve antibiotic prescribing in general practice it is important to focus on both the diagnostic process and the prescribing patterns. The findings indicate an overuse of antibiotics for acute respiratory tract infections in Danish general practice. Especially the diagnostic process and antibiotic prescribing patterns for acute rhinosinusitis and acute bronchitis could benefit from future quality improvement interventions. PMID- 30296886 TI - Educational Attainment and Perceived Need for Urgent Care. AB - While lower educational attainment is associated with worse health status, education may also affect one's ability to identify need for urgent care. Using data from the 2010 Medicare CAHPS survey, we estimated multivariate logistic models to test the relationship between self-reported educational attainment and the perceived need for urgent care, controlling for health status and other factors. As expected, lower educational attainment was associated with greater reported need for urgent care in bivariate analyses because of poorer health. However, lower educational attainment was associated with less perceived need for urgent care after controlling for health status, particularly for those in poor health. These findings suggest the need for interventions to improve the likelihood that people with less education recognize the need for urgent care, particularly those in poor health and in most need of urgent care. PMID- 30296887 TI - Short-term Outcome of Straight vs Tapered Carotid Stenting for Symptomatic Carotid Artery Stenosis: A Prospective Study. AB - PURPOSE: To investigate the short-term outcomes and complications of straight vs tapered carotid stent placement for patients with symptomatic carotid stenosis. METHODS: A prospective study was conducted to examine if tapered carotid stents (TCS) performed better than straight carotid stents (SCS) in terms of complications and outcomes in patients with a unilateral, symptomatic, internal carotid artery stenosis ?70%. Between January 2014 and January 2016, 236 patients were screened; 88 were excluded, leaving 148 patients for 1:1 randomization to carotid artery stenting with either SCS or TCS. The data were analyzed for differences between the groups in terms of complications (hemodynamic depression, cerebral hyperperfusion syndrome, puncture site sequelae) and endpoint events (stroke, myocardial infarction, and death) at 30 days and 6 months. RESULTS: Two patients in the TCS group underwent endarterectomy after allocation, leaving 72 patients (mean age 65.1+/-8.8 years; 59 men) in the TCS group for analysis vs 74 (mean age 65.0+/-7.9 years; 58 men) in the SCS group. The technical success was 100% in both groups. The incidence of hemodynamic depression (hypotension and bradycardia) after the procedures were higher in the SCS group (p=0.04), and the patients who underwent SCS procedures had longer hospital stays (p=0.01). There was no difference in the incidences of complications, myocardial infarction, mortality, or stroke at 30 days or 6 months between the SCS and TCS groups. The rates of restenosis (4% SCS vs 1% TCS) were similar (p=0.63); all restenoses were moderate (50%-70%). CONCLUSION: When compared to straight stents, tapered carotid stents significantly decreased hemodynamic complications and hospital stay. PMID- 30296888 TI - Tapered Carotid Stents: An Essential Modification to Improve Carotid Artery Stenting Outcomes? PMID- 30296889 TI - Does short-term weekly teriparatide improve healing in unstable intertrochanteric fractures? AB - : Slow recovery after hip fracture has been associated with negative consequences. Thus, there is medical need to improve healing and functional recovery after intertrochanteric fracture. The aim of this study was to measure whether short-term teriparatide would improve healing in intertrochanteric fractures after internal fixation as measured by (1) clinical scores, (2) radiographic fracture healing, and (3) complication rates. We retrospectively reviewed 96 patients (average age, 82 years) who underwent closed reduction and internal fixation with proximal femoral nail (PFN) for unstable intertrochanteric fractures between 2014 and 2016. Of the 96 patients, 56 patients were treated with a PFN alone (group 1). These patients were compared with 46 patients for whom the same device was used and a weekly subcutaneous injection of PTH 1-34 (teriparatide) was prescribed postoperatively (group 2). Questionnaire surveys or telephone interviews were conducted, and patients completed a self-report Harris hip score and visual analog scale scores. The radiological time to fracture healing was assessed as the primary end point. Postoperative complication rates were compared. Functional outcomes at 6 months after surgery were similar in both groups. There were no differences between groups in the proportion of patients achieving radiographic fracture healing. The frequency of patients reporting adverse events was 20% (10 of 50) in group 1 versus 17% (8 of 46) in group 2 ( p = 0.744). Short-term teriparatide did not improve radiographic signs of fracture healing of an intertrochanteric fracture and reduce the incidence of complications. The effect of teriparatide on fracture healing remains uncertain. Further multicenter prospective studies are needed to demonstrate objective long term results of parathyroid hormone therapy in patient with hip fracture. LEVEL OF EVIDENCE: Level IV, therapeutic study. PMID- 30296890 TI - Posterior Inferior Turbinate Hypertrophy (PITH). AB - Hypertrophy of the soft tissue of the posterior inferior turbinate (PITH) may be observed during nasal endoscopy, although the clinical significance is not understood. We report a cross-sectional study of consecutive new patients undergoing baseline nasal endoscopy in a tertiary rhinology clinic. Subjects completed 22-Item Sinonasal Outcome Test (SNOT-22) and Nasal Obstruction Symptom Evaluation (NOSE) questionnaires. Of 391 subjects screened, PITH was present in 62 (15.9%), with a female predominance. The prevalence of allergic rhinitis and chronic rhinosinusitis was comparable between PITH and non-PITH groups. Nonpurulent exudate flowing from the posterior inferior turbinate into the nasopharynx was more prevalent in association with PITH (83.9% vs 14.3%, P < .001). Mean SNOT-22 scores and NOSE scores were not significantly different between PITH and non-PITH groups. This preliminary study suggests that PITH is a common physical finding with unclear etiology and should be the subject of further investigation. PMID- 30296891 TI - A third HSAN5 mutation disrupts the nerve growth factor furin cleavage site. AB - Bi-allelic dysfunctional mutations in nerve growth factor (NGF) cause the rare human phenotype hereditary sensory and autonomic neuropathy type 5 (HSAN5). We describe a novel NGF mutation in an individual with typical HSAN5 findings. The mutation c.361C>T, p.R121W is at the last residue of the furin cleavage motif Arg Ser-Lys-Arg in proNGF. We show that the p.R121W mutation completely abolishes the formation of mature NGF-beta. Surprisingly, mutant p.R121W cells produced very little proNGF. Instead, the two progressive cleavage products of proNGF were produced, proA-NGF and proB-NGF, with proB-NGF being the predominant NGF-derived peptide and the only peptide secreted by mutant p.R121W cells. We found that the ability of the p.R121W mutation to cause tropomyosin receptor kinase A autophosphorylation and mitogen-activated protein kinase phosphorylation was significantly reduced compared to controls (p < 0.05 and p < 0.01). By studying the PC12 cell line morphology and neurite length over a week, we found the p.R121W mutation had residual, but much reduced, neurotrophic activity when compared to wild-type NGF. Finally, we assessed whether the p.R121W mutation affected apoptosis and found a reduced protective effect compared to wild-type NGF. Our results suggest that the p.R121W NGF mutation causes HSAN5 through negating the ability of furin to cleave proNGF to produce NGF-beta. PMID- 30296892 TI - Informing efficient pilot development of animal trauma models through quality improvement strategies. AB - Poor quality data in preclinical trials can result from inconsistent and unstandardized experimental processes. Unpredictable pre-intervention variability generates unreliable data, biases outcomes and results in needless waste of animals and resources. We applied Define-Measure-Analyse-Improve-Control (DMAIC) quality improvement processes to pilot development of a swine model of trauma, haemorrhagic shock and coagulopathy. The goal was to reduce variability through protocol standardization and error reduction. Six male Sinclair swine were sequentially anesthetized, intubated, mechanically ventilated and instrumented, then subjected to multiple-hit injury, followed by fluid resuscitation monitoring and coagulation testing. Experimental tasks were defined and mapped. Performance measures were task performance times, subject stabilization time and number of task execution errors. Process improvement was assessed by reduced times and errors, and subject stability at target physiological values. Previously overlooked performance errors and deficiencies were identified. 'Mistake proofing' actions included personnel retraining, revisions of standard operating procedures and use of checklists. The quality improvement pilot trial produced a stable model with reduced protocol deviations. Data quality can be improved and animal waste minimized, if experimental planning incorporates strategies to ensure protocol adherence and reduced operator performance variation and errors. Properly designed pilot trials can be essential components of refinement and reduction strategies in animal-based research. PMID- 30296893 TI - Intraductal Pneumatic Lithotripsy after Extended Transoral Duct Surgery in Submandibular Sialolithiasis. AB - Objective Persistent, residual, or recurrent stones after transoral duct surgery are always associated with hilar to intraparenchymal and/or multiple sialolithiasis, causing difficulties in the treatment. This study was performed to assess the value of intraductal lithotripsy in the treatment of persistent, residual, or recurrent sialolithiasis after extended duct surgery in the submandibular gland. Study Design Retrospective study covering February 2015 to June 2018. Study Setting Tertiary referral center for salivary gland diseases. Subjects and Methods After extended ductal surgery, 39 patients presenting with persistent, residual, or recurrent stones were treated. Four patients had persistent stones; 16 had residual stones; and 19 presented with recurrent stones. Among these patients, 50 stones were treated with intraductal pneumatic lithotripsy. Fragmentation rate, stone-free rate, and symptom-free rate after treatment with intraductal lithotripsy were outcome measures. Results Of the 39 patients, 97.4% became stone-free, and all were symptom-free. Ninety-eight percent of the stones were completely fragmented. For 23.1% of the patients, >1 stone was treated with intraductal lithotripsy. All patients with persistent stones, 93.7% of those with residual stones, and all with recurrent stones became stone-free and symptom-free. No severe complications developed. Conclusions This study shows that patients presenting with difficult and/or multiple sialolithiasis after extended transoral submandibular duct surgery can be treated with success rates >97%. For multiple sialolithiasis in particular, a multimodal treatment approach with interventional sialendoscopy and intraductal lithotripsy as a central element is a prerequisite for success, as this enables the most difficult part to be performed with high success rates. PMID- 30296894 TI - Neuropsychological predictors of patient-reported cognitive decline after deep brain stimulation in Parkinson's disease. AB - BACKGROUND: Deep brain stimulation (DBS) is effective for treatment of motor complications of dopaminergic therapy in Parkinson's disease (PD) but occasionally has been associated with multidomain cognitive decline. Patient- and caregiver-reported cognitive decline are clinically meaningful and increasingly recognized as important to consider when evaluating therapeutic interventions for PD. OBJECTIVE: The objective was to assess presurgical neuropsychological and clinical factors associated with PD patient- and caregiver-reported cognitive decline in two or more domains after DBS. METHOD: A single telephone survey was used to assess patient- and caregiver-reported cognitive decline in five domains at both one and four months after DBS surgery. Decline in two or more domains was considered multidomain cognitive decline (MDCD). Baseline demographic, clinical, and neuropsychological factors were compared in those with or without MDCD. Preoperative neuropsychological measures were evaluated as risk factors and regressed on the presence of MDCD, with demographic covariates, using multiple logistic regression. RESULTS: Preoperative performance in verbal recognition memory, language knowledge, and verbal processing decline were associated with postoperative, patient-reported MDCD in the first four weeks. MDCD at four months after DBS was associated with worse preoperative verbal reasoning, verbal recall, and semantic verbal fluency. Caregiver-reported MDCD one month after DBS was associated with poorer baseline verbal memory recognition accuracy/discriminability, visuospatial problem solving, and constructional praxis. CONCLUSION: Poor presurgical performance in verbal memory recognition, language processing, and visuospatial performance is associated with patient- or caregiver-reported decline following DBS surgery. Posterior cortical dysfunction seems to portend significant self-reported cognitive decline following deep brain stimulation. PMID- 30296895 TI - Drug Targets for Heart Failure with Preserved Ejection Fraction: A Mechanistic Approach and Review of Contemporary Clinical Trials. AB - Heart failure with preserved ejection fraction (HFpEF) accounts for over half of prevalent heart failure (HF) worldwide, and prognosis after hospitalization for HFpEF remains poor. Due, at least in part, to the heterogeneous nature of HFpEF, drug development has proved immensely challenging. Currently, there are no universally accepted therapies that alter the clinical course of HFpEF. Despite these challenges, important mechanistic understandings of the disease have revealed that the pathophysiology of HFpEF is distinct from that of HF with reduced ejection fraction and have also highlighted potential new therapeutic targets for HFpEF. Of note, HFpEF is a systemic syndrome affecting multiple organ systems. Depending on the organ systems involved, certain novel therapies offer promise in reducing the morbidity of the HFpEF syndrome. In this review, we aim to discuss novel pharmacotherapies for HFpEF based on its unique pathophysiology and identify key research strategies to further elucidate mechanistic pathways to develop novel therapeutics in the future.

AB - For decades, symptoms of depression have been treated primarily with medications that target the monoaminergic brain systems, which typically take weeks to exert measurable effects and months to exert remission of symptoms. Low, subanesthetic doses of (R,S)-ketamine (ketamine) result in the rapid improvement of core depressive symptoms, including mood, anhedonia, and suicidal ideation, occurring within hours following a single administration, with relief from symptoms typically lasting up to a week. The discovery of these actions of ketamine has resulted in a reconceptualization of how depression could be more effectively treated in the future. In this review, we discuss clinical data pertaining to ketamine and other rapidacting antidepressant drugs, as well as the current state of pharmacological knowledge regarding their mechanism of action. Additionally, we discuss the neurobiological circuits that are engaged by this drug class and that may be targeted by a future generation of medications, for example, hydroxynorketamine; metabotropic glutamate receptor 2/3 antagonists; and N-methyl Daspartate, alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid, and gamma aminobutyric acid receptor modulators.

AB - Race and ancestry have long been associated with differential risk and outcomes to disease as well as responses to medications. These differences in drug response are multifactorial with some portion associated with genomic variation. The field of pharmacogenomics aims to predict drug response in patients prior to medication administration and to uncover the biological underpinnings of drug response. The field of human genetics has long recognized that genetic variation differs in frequency between ancestral populations, with some single nucleotide polymorphisms found solely in one population. Thus far, most pharmacogenomic studies have focused on individuals of European and East Asian ancestry, resulting in a substantial disparity in the clinical utility of genetic prediction for drug response in US minority populations. In this review, we discuss the genetic factors that underlie variability to drug response and known pharmacogenomic associations and how these differ between populations, with an emphasis on the current knowledge in cardiovascular pharmacogenomics.

PMID- 30296898 TI - Impact of a Clinical Trial in Two District Hospitals in Ghana: Perspectives of Ghanaian Researchers. AB - Conducting clinical trials in resource-poor settings may contribute to local capacity building. We describe the perspectives of local research personnel regarding the impact of collaborating in a clinical trial in rural Ghana. Forty six Ghanaian research personnel were eligible to complete an anonymous survey, and 35 (76%) participated. Of the 35 respondents, 32 (91%) agreed that future patients will benefit because the hospital was part of the study. All 35 respondents reported a personal benefit derived from study involvement, most commonly citing skills or knowledge gained. Of the 35 individuals, 21 reported one or more burdens, most commonly citing nonspecific research responsibilities. Our data support the hypothesis that participation in clinical trials can contribute to capacity building in district hospitals in a lower middle-income country. PMID- 30296899 TI - MAP1A/BLC3? Now I am really confused. AB - I routinely see people use incorrect names for MAP1LC3/LC3 isoforms in scientific papers. In fact, it happens often enough that I decided to investigate the reason for the apparent confusion. It turns out that the sources of misinformation are abundant, including UniProt and antibody supplier web sites. PMID- 30296900 TI - Innovations in Ventricular Assist Devices for End-Stage Heart Failure. AB - The number of patients with end-stage heart failure (HF) continues to increase over time, but there has been little change in the availability of organs for cardiac transplantation, intensifying the demand for left ventricular assist devices (LVADs) as a bridge to transplantation. There is also a growing number of patients with end-stage HF who are not transplant candidates but may be eligible for long-term support with an LVAD, known as destination therapy. Due to this increasing demand, LVAD technology has evolved, resulting in transformative improvements in outcomes. Additionally, with growing clinical experience patient management continues to be refined, leading to iterative improvements in outcomes. With outcomes continuing to improve, the potential benefit from LVAD therapy is being considered for patients earlier in their course of advanced HF. We review recent changes in technology, patient management, and implant decision making in LVAD therapy.

PMID- 30296902 TI - Survival Outcomes for Induction vs Adjuvant Chemotherapy in Squamous Cell Carcinoma of the Maxillary Sinus. AB - Objective In advanced maxillary sinus cancers treated with surgery and radiotherapy, poor local control rates and the potential for organ preservation have prompted interest in the use of systemic therapy. Our objective was to present outcomes for induction compared to adjuvant chemotherapy in the maxillary sinus. Study Design Secondary database analysis. Setting National Cancer Database (NCDB). Subjects and Methods In total, 218 cases of squamous cell maxillary sinus cancer treated with surgery, radiation, and chemotherapy between 2004 and 2012 were identified from the NCDB and stratified into induction chemotherapy and adjuvant chemotherapy cohorts. Univariate Kaplan-Meier analyses were compared by log-rank test, and multivariate Cox regression was performed to evaluate overall survival when adjusting for other prognostic factors. Propensity score matching was also used for further comparison. Results Twenty-three patients received induction chemotherapy (10.6%) and 195 adjuvant chemotherapy (89.4%). The log rank test comparing induction to adjuvant chemotherapy was not significant ( P = .076). In multivariate Cox regression when adjusting for age, sex, race, comorbidity, grade, insurance, and T/N stage, there was a significant mortality hazard ratio of 2.305 for adjuvant relative to induction chemotherapy (confidence interval, 1.076-4.937; P = .032). Conclusion Induction chemotherapy was associated with improved overall survival in comparison to adjuvant chemotherapy in a relatively small cohort of patients (in whom treatment choice cannot be characterized), suggesting that this question warrants further investigation in a controlled clinical trial before any recommendations are made. PMID- 30296901 TI - Systematic Review of Supraclavicular Artery Island Flap vs Free Flap in Head and Neck Reconstruction. AB - Objective The aim of this systematic review is to compare the surgical outcomes of supraclavicular artery island flap (SCAIF) and free tissue transfer (FTT) in head and neck reconstruction. Data Sources PubMed, Web of Science, and EMBASE databases. Review Methods Independent screening and data extraction were performed by 2 authors. Only studies that directly compared SCAIF and FTT were included. Data were pooled with random-effects meta-analysis to determine the standardized mean differences (SMDs), risk differences, and 95% confidence intervals (CIs). Heterogeneity was assessed using the I2 statistics. The Methodological Index for Non-Randomized Studies tool was used to evaluate extent of bias in studies. Results The initial query yielded 661 results, of which 4 comparative studies remained for final analysis. The pooled sample sizes for the SCAIF and FTT cohorts were 100 and 84, respectively. SCAIF was associated with reduction of operative time by a large effect size (SMD, 1.65; 95% confidence interval, 0.78-2.52). The harvested flap areas and perioperative complications, including rates of total flap loss, partial flap necrosis, and recipient/donor site dehiscences, were comparable between the 2 procedures with low to high heterogeneity among studies. Conclusion SCAIF requires less operative time and has comparable short-term perioperative results to FTT. The findings of this study support the viability of SCAIF as an alternative to FTT and provide evidence for its inclusion in the reconstructive armamentarium of major head and neck ablation and trauma. PMID- 30296903 TI - Prevalence of vitamin D deficiency in Iran: A systematic review and meta analysis. AB - BACKGROUND: The prevalence of vitamin D deficiency in the Iranian community is very high. Women and older people are at the higher risk of vitamin D deficiency. AIM: This study aimed to estimate the prevalence of vitamin D deficiency in Iran by combining the results of various studies. METHODS: This was a systematic review and meta-analysis. Separate strategies were developed for search in national databases (Irandoc, Magiran, SID) and international databases (Web of Science, PubMed, and Scopus) using the keywords of "vitamin D deficiency," "Iran," and "prevalence." The titles and abstracts of the articles were screened and related full texts were appraised. Those articles that met inclusion criteria were selected for meta-analysis. The heterogeneity of the articles was assessed via the Chi-square test. They were combined using the random-effect approach. In addition, the groups were categorized and analyzed in terms of age and gender. RESULTS: Of 639 articles, 30 articles with a sample size of 26,042 people were included for data analysis. The overall prevalence of vitamin D deficiency was reported as 0.56. Subgroup analysis showed that 0.64 of women and 0.44 of men were suffering from vitamin D deficiency. The prevalence of vitamin D deficiency in the age groups under 20, 20-50, and over 50 years was 0.56.4, 0.72.4, and 0.59.8, respectively. CONCLUSIONS: The Iranian Ministry of Health is expected to design strategies to improve the status of vitamin D at the national level. PMID- 30296905 TI - Gross Pathology of Routine Pediatric Tonsillectomy Specimens: Optimizing the Value of Patient Care. AB - Objective This investigation seeks to evaluate the effect of gross pathologic analysis on our management of patients undergoing routine tonsillectomy and to evaluate charges and reimbursement. Study Design Retrospective chart review from 2005 through 2016. Setting Academic medical center. Subjects and Methods Participants were pediatric patients aged 14 years and younger undergoing tonsillectomy for either sleep-disordered breathing or tonsillitis, with tonsillectomy specimens evaluated by pathology, and without any risk factors for pediatric malignancy. Records were reviewed for demographics, surgical indications, and pathology. Abnormal reports prompted an in-depth review of the chart. Charges and reimbursement related to both hospital and professional fees for gross tonsil analysis were evaluated. Results From 2005 to 2016, 3183 routine pediatric tonsillectomy cases were performed with corresponding specimens that were sent for gross analysis revealing no significant pathologic findings; 1841 were males and 1342 were females. Ten cases underwent microscopy by pathologist order, revealing normal tonsillar tissue. The mean charge per patient for gross analysis was $60.67 if tonsils were together as 1 specimen and $77.67 if tonsils were sent as 2 separate specimens; respective reimbursement amounts were $28.74 and $35.90. Conclusions Gross pathologic analysis did not change our management of routine pediatric tonsillectomy patients. Foregoing the practice at our institution would eliminate $19,171.72 to $24,543.72 in charges and $9081.40 to $11,344.40 in reimbursement per year. Eliminating this test would improve the value of patient care by saving health care resources without compromising clinical outcomes. PMID- 30296904 TI - Psychosocial functioning following moderate-to-severe pediatric traumatic brain injury: recommended outcome instruments for research and remediation studies. AB - Psychosocial functioning is compromised following pediatric traumatic brain injury (TBI), with the past few decades witnessing a proliferation of research examining the effect of childhood brain insult on a range of psychosocial outcomes. This paper describes the systematic recommendation of outcome instruments to address psychosocial functioning following pediatric TBI. A total of 65 instruments across 11 psychosocial areas (i.e., Global Outcome, Communication, Social Cognition, Behavioural and Executive Function, Other Neuropsychological Functioning, Psychological Status, TBI-related Symptoms, Activities and Participation, Support and Relationships, Sense of Self, and Health-Related Quality of Life) were reviewed using various assessment methods, including working groups, literature searches, comparisons with selection guidelines, and international expert opinion. Each measure was reviewed for its usefulness across early recovery, intervention, and outcome related studies. 34 instruments were recommended and classified according to the World Health Organization's International Classification of Functioning, Disability and Health taxonomy and categorised by psychosocial area. This compilation provides a common framework to guide the activities of clinicians and researchers in psychosocial rehabilitation. It is anticipated that these will foster a multidisciplinary approach to psychosocial dysfunction to enhance the evaluation, prediction, and improvement of functional outcomes for those with pediatric TBI. PMID- 30296906 TI - Geographic and Racial Disparities in Infant Hearing Loss. AB - Objective Approximately 1 to 2 of every 1000 American newborns has hearing loss identified by newborn screening. This study was designed to determine if infant hearing loss is more common in socioeconomically disadvantaged communities. Study Design In this retrospective study, we analyzed electronic medical record data using geostatistical models. Setting Infants were residents of Durham County, North Carolina, born in 2 hospitals of the Duke University Health System. This county includes the city of Durham and surrounding suburban and rural communities. Subjects and Methods Subjects were hearing-screened newborns, born between 2005 and 2016, whose residential address was in Durham County, North Carolina. This was a retrospective study using medical record data. We used Bayesian regression models with smoothing of coordinate date to identify both spatial and nonspatial predictors of infant hearing loss. Results We identified 19,348 infants from Durham County, of whom 675 had failed initial hearing screening and 191 had hearing loss confirmed on follow-up. Hearing loss was significantly associated with minority race (odds ratio [OR], 2.45; 95% confidence interval, 1.97-3.06), as well as lower gestational age and maternal sexually transmitted infections. We identified significant geographic heterogeneity, with a higher probability of hearing loss in poorer urban neighborhoods (local OR range, 0.59-1.39). Neighborhood disadvantage was a significant predictor of hearing loss, as was high local seroprevalence of cytomegalovirus (CMV) among pregnant women. Conclusions Urban, low-income neighborhoods have a high prevalence of infant hearing loss compared with more affluent surrounding communities, particularly among minorities. This distribution may be attributable to congenital CMV infection. PMID- 30296907 TI - Arterial Switch Operation in a Patient With Ehlers-Danlos Syndrome Type IV. AB - Ehlers-Danlos syndrome vascular type IV is characterized by translucent skin, easy bruising, and fragility of arteries. A full-term female infant presented at four weeks of age with a diagnosis of d-transposition of the great arteries with restrictive atrial septal defect. She successfully underwent emergent balloon atrial septostomy and placement of patent ductus arteriosus (PDA) stent. She required restenting of the PDA and pulmonary artery banding prior to arterial switch procedure. At 16 months of age, the patient successfully underwent arterial switch procedure without complication. This report demonstrates the feasibility of an arterial switch operation along with long-term follow-up of this rare condition. PMID- 30296908 TI - "Neither a wife nor a widow": an interpretative phenomenological analysis of the experiences of female family caregivers in disorders of consciousness. AB - Disorders of consciousness (DoC) disrupt close relationships. This study investigated the experience of a DoC in the family. Four main themes were identified from semi-structured interviews with nine females and analysed using Interpretative Phenomenological Analysis (IPA): (1) Loss without a name, (2) Relationship without a title, (3) Symbiotic relating and (4) Frozen futures. Participants' accounts showed complex losses and relationship transformations that were challenging to cope with. Participants embodied the person and experienced reductions in rehabilitation and social visits as personally abandoning and led to strong advocacy with professionals. The uncertainty created by the DoC meant participants lived in the present moment and struggled to make plans for their future. Psychological support to demonstrate a sensitivity and validation of this unique complex loss, a framework for naming the loss, provision of education about the condition and enhancing coping with a chronic situation are needed. PMID- 30296909 TI - Motivational-general arousal imagery does not improve decision-making performance in elite endurance cyclists. AB - Emotions are predicted to influence judgement and decision-making across a range of performance contexts. This experiment tested whether motivational-general arousal imagery can improve the decision-making performance of elite endurance cyclists. In total, 54 cyclists (38 men, 16 women) were assigned to either a positive imagery condition (where positive images associated with the affective experience of winning were encouraged) or a negative imagery condition (where negative images associated with poor performance were encouraged). The cyclists were read one of two scripts designed to elicit positive or negative images during a 20-min maximal sustainable interval on a cycle ergometer. A decision making task (colour-word match Stroop) was performed before and immediately after the maximal sustainable power interval. Results showed that the manipulation was successful with cyclists in the positive imagery condition reporting more positive affective states (higher levels of happiness and lower levels of dejection) than those in the negative imagery condition. However, there was no significant difference between the two groups in their decision-making performance under physiological duress. These findings indicate that while motivational-general arousal imagery might be a useful method to induce positive emotions during exercise, it is unlikely to improve the decision-making performance of cyclists in performance-relevant conditions. PMID- 30296910 TI - Mitochondrial DNA Copy Number in Peripheral Blood in the First Trimester of Pregnancy and Different Preeclampsia Clinical Phenotypes Development: A Pilot Study. AB - Inflammation and oxidative stress are intrinsically linked to early poor placentation, typical of pregnancies complicated by preeclampsia associated with intrauterine growth restriction (PE-IUGR). Low mitochondrial DNA copy number (mtDNAcn) in peripheral blood constitutes a good peripheral surrogate marker of inflammation and oxidative stress. On these basis, we explored a possible correlation between mtDNAcn in peripheral blood in the first trimester of pregnancy and the PE-IUGR onset. To shed light on this issue, we setup a nested case-control study from a prospective cohort of pregnant women undergoing first trimester aneuploidies screening. Two groups of patients affected by PE classified according to the clinical phenotype were identified: (1) patients who developed PE-IUGR and (2) patients who developed PE associated with appropriate for gestational age intrauterine fetal growth (PE-AGAf). Controls were women with a physiologic pregnancy matched to cases on the basis of age (+/-6 months, ratio 2:1). Mitochondrial DNA copy number was quantified using real-time polymerase chain reaction and normalized to nuclear DNA. The median (interquartile range) mtDNAcn in peripheral blood in patients with PE-IUGR (n = 12) and in patients with PE-AGAf (n = 16) was 70 (44-97) and 108 (95-145), respectively ( P = .004). Both these values were significantly lower than that detected in the control group (161[133-183], P < .001). The area under the receiver-operator curve for PE IUGR and PE-AGAf were 0.94 (95% confidence interval [CI]: 0.88-1.00, P < .001) and 0.81 (95%CI: 0.70-0.91, P < .001), respectively. In conclusion, MtDNAcn in peripheral blood resulted significantly lower both in patients affected by PE IUGR and in those affected by PE-AGAf when compared to controls. The accuracy of this biomarker resulted particularly good in predicting PE-IUGR. PMID- 30296911 TI - Contemporary Insights from Biblical Combat Veterans through the Lenses of Moral Injury and Post-Traumatic Stress Disorder. AB - This psychological exegesis reconsiders biblical characters through recent theories on moral injury and post-traumatic stress disorder (PTSD). The purposes of this article are to shed new light on these characters and to engage in conversations of what the findings may mean for pastoral care and their connections to theology. The findings include the proposal of four categorical types of combat veterans that illustrate the development of PTSD, resilience, moral injury, and unfaltering abidance to the warrior ethics. PMID- 30296912 TI - The Effect of Sphenopalatine Block on the Postoperative Pain of Endoscopic Sinus Surgery: A Meta-analysis. AB - Objectives The use of sphenopalatine ganglion block (SPGB) with a local anesthetic to decrease postoperative pain after endoscopic sinus surgery (ESS) is controversial. We investigated the role of a perioperative SPB to minimize postoperative pain related to ESS in patients with chronic sinusitis through a systematic review of the relevant literature. Data Sources PubMed, SCOPUS, Google Scholar, Embase, and the Cochrane Register of Controlled Trials. Review Methods We screened the relevant literature published before June 2018. Eight articles that compared perioperative SPGB (treatment group) with a placebo or no treatment (control group) were included for this analysis of the outcomes, which included perioperative morbidities in ESS. For quantitative variables, the standardized mean difference was applied to standardize and summate the results of the studies, and the odds ratio was used in outcome of incidence analysis. Results Intraoperative bleeding ( P < .0001), postoperative pain ( P = .0001), nausea and vomiting ( P = .0117), and recovery from sedation ( P < .0001) in the treatment group were significantly reduced compared with the control group. No significant adverse effects were reported in the enrolled studies. In subgroup analyses according to the SPGB approach (transoral or transnasal), the transnasal approach showed higher positive effects on intraoperative bleeding and postoperative pain compared to the transoral approach. Conclusion In our study, SPGB combined with a local anesthetic for ESS effectively reduced intra-and postoperative morbidities. This procedure showed no significant adverse effects. Given the ease and effectiveness of this procedure, the transnasal approach should be highly recommended as a routine procedure compared to the transoral approach. PMID- 30296913 TI - How visual memory changes with intervening recall. AB - Being asked to recount a visual memory is common in educational settings, spatial navigation, and crime investigation. Previous studies show that recounting one's memory can benefit subsequent memory, but most of this work either used verbal materials or conflated category memory with memory for visual details. To test whether recounting may introduce visually-specific interference effects, we tested people's memory for photographs of objects, but introduced an intervening phase in which people described their memory. We separated memory for the specific exemplar from memory for the basic-level category. Contrary to recent findings on maps and colours, the intervening retrieval practice did not consistently strengthen exemplar memory of objects. Instead, recounting one's visual memory appeared to introduce interference that sometimes cancelled the benefit of increased retrieval effort. Delaying the final memory test by 24 hr increased the benefit of retrieval practice. These findings suggest that intervening retrieval has multiple effects on visual memory. Instead of being a snapshot, this memory constantly changes with retrieval practice and with time. PMID- 30296914 TI - Mutated Thyroid Hormone Transporter OATP1C1 Associates with Severe Brain Hypometabolism and Juvenile Neurodegeneration. AB - BACKGROUND: Thyroid hormones (TH) are essential for brain development and function. The TH transporters monocarboxylate transporter 8 (MCT8) and organic anion transporter1 C1 (OATP1C1) facilitate the transport of TH across the blood brain barrier and into glia and neuronal cells in the brain. Loss of MCT8 function causes Allan-Herndon-Dudley syndrome (AHDS, OMIM 300523) characterized by severe intellectual and motor disability due to cerebral hypothyroidism. Here, the first patient with loss of OATP1C1 function is described. The patient is a 15.5-year-old girl with normal development in the first year of life, who gradually developed dementia with spasticity and intolerance to cold. Brain imaging demonstrated gray and white matter degeneration and severe glucose hypometabolism. METHODS: Exome sequencing of the patient and parents was performed to identify the disease-causing mutation, and the effect of the mutation was studied through a panel of in vitro experiments, including thyroxine uptake studies, immunoblotting, and immunocytochemistry. Furthermore, the clinical effects of treatment with the triiodothyronine analogue triiodothyroacetic acid (Triac) are described. RESULTS: Exome sequencing identified a homozygous missense mutation in OATP1C1, changing the highly conserved aspartic acid 252 to asparagine (D252N). In vitro, the mutated OATP1C1 displays impaired plasma membrane localization and decreased cellular thyroxine uptake. After treatment with Triac, the clinical condition improved in several domains. CONCLUSIONS: This is the first report of human OATP1C1 deficiency compatible with brain-specific hypothyroidism and neurodegeneration. PMID- 30296915 TI - Contradiction processing in schizophrenia. AB - INTRODUCTION: Patients with schizophrenia present clinically with difficulties in manipulating contradictory information in the form of loose associations, surface contradictions and delusional beliefs. It is to date unclear whether patients can detect and process information that contradicts their beliefs and prior knowledge and whether this capacity is related to their symptoms and the nature of contradictory stimuli (e.g., personally significant information, emotional information). METHODS: We probed contradiction processing in patients with schizophrenia and healthy controls using sentence verification tasks that involve self-referential judgements (Experiment 1) and general knowledge (Experiment 2), while manipulating the emotional content of the stimuli. RESULTS: We found no differences between patients and controls either on reaction time (Experiment 1 & 2) or accuracy measures (Experiment 1). CONCLUSIONS: Our results show no general impairment in contradiction processing in schizophrenia. Rather, failures to detect and correct contradictions in symptoms such as formal though disorder or delusions could arise through a complex interplay between executive dysfunctions, stress and the emotional content of the information. PMID- 30296916 TI - High subsequent and recurrent sexually transmitted infection prevalence among newly diagnosed HIV-positive Thai men who have sex with men and transgender women in the Test and Treat cohort. AB - We determined subsequent and recurrent sexually transmitted infections (STIs) among men who have sex with men (MSM) and transgender women (TGW) in the Test and Treat cohort. Thai MSM and TGW adults with previously unknown HIV status were enrolled and tested for HIV. Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and syphilis were tested at baseline, month 12, and month 24 to identify subsequent STIs (any STIs diagnosed after baseline) and recurrent STIs (any subsequent STIs diagnosed among those with positive baseline STIs). Among 448 participants, 17.8% were HIV-positive, the prevalence of subsequent STIs and recurrent STIs was 42% (HIV-positive versus HIV-negative: 66.3% versus 36.7%, p < 0.001) and 62.3% (81% versus 52.5%, p < 0.001), respectively. Common subsequent STIs by anatomical site were rectal CT infection (21.7%), rectal NG infection (13.8%), pharyngeal NG infection (13.1%), and syphilis (11.9%). HIV-positive status was associated with both subsequent STIs (adjusted hazard ratio [aHR] 2.38; 95%CI 1.64-3.45, p < 0.001) and recurrent STIs (aHR 1.83; 95%CI 1.16-2.87, p = 0.01). The results show that newly diagnosed HIV-positive MSM and TGW were at increased risk of STIs despite being in the healthcare system. STI educational counseling is necessary to improve STI outcomes among MSM and TGW in both HIV prevention and treatment programs. PMID- 30296917 TI - Understanding the Role of Telomere Dynamics in Normal and Dysfunctional Human Reproduction. AB - In modern society, fertility problems and demand of treatment seem to be on the rise, which led to an increased interest in research regarding human reproduction. Among these efforts, the study of the molecular senescence process has gain notorious popularity as aging is one of the most important variables involved in reproductive capacity and since the comprehension of telomere dynamics has become an important and influential theme. This new knowledge regarding the reproductive aging process is expected to offer new tools to understand the acquisition, maintenance, and loss of fertility potential. Therefore, this review seeks to clarify the relevance of molecular aging (evaluated by telomere shortening) in human reproduction, showing that it is a dynamic and variable process modulated according to the specific tissue and stage of development. As well, it is discussed how telomere status influence the development and progression of some fertility pathologies, the outcome of assisted reproductive treatments, and programming of aging in the offspring. PMID- 30296918 TI - Attachment to God and Death Anxiety in Later Life: Does Race Matter? AB - Research suggests that religion plays a critical role in individuals' attitudes toward death in later life. The purpose of this study is to investigate whether a previously unexamined aspect of religion-secure attachment to God-is associated with death anxiety among U.S. older adults and whether this association varies across race. Using longitudinal data from a representative sample of adults aged 65 and older ( N = 936), the analyses reveal that secure attachment to God is associated with a decrease in death anxiety over time. Furthermore, the negative association between secure attachment to God and change in death anxiety is greater for older Blacks than their White counterparts. These results indicate that religion serves a protective function against death anxiety in later life. Moreover, religion provides greater psychological benefits for older Blacks than older Whites, reinforcing a long-standing claim that religion is particularly valuable for individuals from marginalized backgrounds. PMID- 30296919 TI - Medication-related osteonecrosis of the jaw: An institution's experience. AB - OBJECTIVES: This study aimed to evaluate and report the outcomes associated with the management of patients who were treated surgically for medication-related osteonecrosis of the jaw (MRONJ). METHODS: Demographic and medical profiles of patients with a diagnosis of MRONJ were created. The type of surgical treatment, complications, and treatment outcomes were identified. RESULTS: Twenty-one patients with an average age of 68.42 years (range 40-90 years) were included. Nineteen patients had only mandible involvement, one patient had only maxilla involvement, and one patient had both mandible and maxilla involvement. Thirteen patients underwent marginal resections. Eight patients underwent segmental resection of the mandible with immediate reconstruction. Nineteen patients healed without any complications. Two patients who had undergone segmental resection of the mandible experienced postoperative complications and needed a second surgery to achieve primary closure. DISCUSSION: Advanced MRONJ can effectively be treated with resective surgery in combination with medical treatment. PMID- 30296920 TI - Efficacy of dry needling in patients with myofascial temporomandibular disorders related to the masseter muscle. AB - OBJECTIVE: This randomized, single-center clinical trial aimed to compare the efficacy of superficial dry needling (SDN) and deep dry needling (DDN) in patients with myofascial temporomandibular disorder (MTMD) related to the masseter muscle. METHODS: Forty patients showing MTMD with trigger points in the masseter muscle were randomly assigned to groups. Dry needling of the masseter muscle was performed once per week for three weeks. Pressure pain threshold (PPT) measurements, visual analog scale scores, and maximal jaw opening were assessed. RESULTS: Both patient groups showed significant pain reduction, but the SDN group showed significantly better pain reduction. The PPT measurements obtained in the follow-up examinations at three and six weeks were significantly better than the values in SDN and DDN groups. DISCUSSION: SDN showed better pain-reduction efficacy in patients with MTMD. Further research with a larger size sample and a longer follow-up period will help elucidate the benefits of SDN. PMID- 30296921 TI - "It's Hard Work": A Feminist Political Economy Approach to Reconceptualizing "Work" in the Cancer Context. AB - Within mainstream cancer literature, policy documents, and clinical practice, "work" is typically characterized as being synonymous with paid employment, and the problem of work is situated within the "return to work" discourse. The work that patients perform in managing their health, care, and everyday life at times of illness, however, is largely overlooked and unsupported. Drawing on feminist political economy theory, we report on a qualitative study of 12 women living with cancer. Major findings show that the work of patienthood cut across multiple fields of practice and included both paid and unpaid labor. The most prevalent types of work included illness work, body work, identity work, everyday work, paid employment and/or the work of maintaining income, and coordination work. The findings of this study disrupt popular conceptualizations of work and illuminate the nuanced and often invisible work that cancer patients may encounter, and the health consequences and inequities therein.

AB - The glucagon-like peptide-1 receptor (GLP-1R) is a well-known target of therapeutics industries for the treatment of various metabolic diseases like type 2 diabetes and obesity. The structural-functional relationships of small molecule agonists and GLP-1R are yet to be understood. Therefore, an attempt was made on structurally known GLP-1R agonists (Compound 1, Compound 2, Compound A, Compound B, and (S)-8) to study their interaction with the extracellular domain of GLP-1R. In this study, we explored the dynamics, intrinsic stability, and binding mechanisms of these molecules through computational modeling, docking, molecular dynamics (MD) simulations and molecular mechanics Poisson-Boltzmann surface area (MM/PBSA) binding free energy estimation. Molecular docking study depicted that hydrophobic interaction (pi-pi stacking) plays a crucial role in maintaining the stability of the complex, which was also supported by intermolecular analysis from MD simulation study. Principal component analysis suggested that the terminal ends along with the turns/loops connecting adjacent helix and strands exhibit a comparatively higher movement of main chain atoms in most of the complexes. MM/PBSA binding free energy study revealed that non-polar solvation (van der Waals and electrostatic) energy subsidizes significantly to the total binding energy, and the polar solvation energy opposes the binding agonists to GLP-1R. Overall, we provide structural features information about GLP-1R complexes that would be conducive for the discovery of new GLP-1R agonists in the future for the treatment of various metabolic diseases.

AB - This qualitative study conducted in France of "individuals living with a pemphigus" (ILPs; N = 54) highlights the taxing diagnostic trajectory of those suffering from these rare autoimmune diseases. Beyond enduring a diagnostic period that may prove long, during their numerous medical appointments, these individuals internalize the expectations of the medical professionals who are treating them. In some cases, numerous inconclusive medical tests and, at times, a doctor's condescension may push the patient toward a process of renunciation. This article relates the ILPs' critiques of the medical work conducted during the trying diagnostic period. PMID- 30296924 TI - Nothing and Everything: Fibromyalgia as a Diagnosis of Exclusion and Inclusion. AB - The diagnostic process promises a label that validates patients' embodied experiences and a road map for living with and treating illness. Drawing on 31 qualitative interviews with women and men in Canada and the United Kingdom who have been diagnosed with fibromyalgia (FM), in this article, I examine the participants' experiences of the diagnostic process and how they feel about receiving this label. The interviews reflect that the FM label is plagued by uncertainty because the diagnosis is based on the absence of verifiable pathology. The respondents' narratives also reveal that FM is a vague diagnosis that includes a multitude of symptoms, overlaps with several other diagnoses, and results in feelings of doubt regarding whether it is the correct label. Thus, the participants' narratives reflect that the FM diagnosis is largely an empty promise because it fails to provide definitive answers or confer meaning and legitimacy to their illness experiences. PMID- 30296925 TI - Block of Granulocyte-Macrophage Colony-Stimulating Factor Prevents Inflammation Induced Preterm Birth in a Mouse Model for Parturition. AB - OBJECTIVE: A multitude of factors promotes inflammation in the reproductive tract leading to preterm birth. Macrophages peak in the cervix prior to birth and their numbers are increased by the cytokine granulocyte-macrophage colony-stimulating factor (GM-CSF). We hypothesize GM-CSF is produced from multiple sites in the genital tract and is a key mediator in preterm birth. STUDY DESIGN: Ectocervical, endocervical, and amniotic fluid mesenchymal stem cells were treated with lipopolysaccharide (LPS), and the concentration and expression of GM-CSF was measured. Pregnant CD-1 mice on gestational day 17 received LPS and an intravenous injection of either anti-mouse GM-CSF or control antibody. After 6 hours, the preterm birth rate was recorded. RESULTS: Treatment with LPS increased the GM-CSF concentration and messenger RNA expression after 24 hours in all 3 cell lines ( P < .01). Mice treated with LPS and the GM-CSF antibody had a preterm birth rate of 25%, compared to a 66.7% preterm birth rate in controls, within 6 hours ( P < .05, chi2). Treatment with the anti-mouse GM-CSF antibody decreased the concentration of GM-CSF in the mouse serum ( P < .01) but did not alter the number of macrophages or collagen content in the cervix. CONCLUSION: These studies demonstrate that GM-CSF is produced from multiple sites in the genital tract and that treatment with an antibody to GM-CSF prevents preterm birth. Curiously, the anti-mouse GM-CSF antibody did not decrease the number of macrophages in the cervix. Further research is needed to determine whether antibodies to GM-CSF can be utilized as a therapeutic agent to prevent preterm birth. PMID- 30296926 TI - Exploratory Research Focusing on Oral Cancer Prevention: Challenges of Dealing With Informational and Cognitive Barriers. AB - Oral cancer is a considerable public health problem, and a low level of awareness and knowledge about this tumor and its risk factors is prevalent. To gain a profound understanding of risks groups and to identify suitable communication strategies for a prevention campaign in Northern Germany, an exploratory research was realized. In semistructured face-to-face interviews, the participants of the study ( n = 28) described their individual oral cancer-related perceptions and information-seeking behaviors. A computer-assisted qualitative data analysis showed a vague but also deterring picture of cancer combined with restricted attitudes toward the topic and an inactive or even avoiding information behavior. Four underlying cognitive patterns of self-distancing were identified: (a) optimistic bias, (b) fatalism, (c) hedonism, and (d) pragmatism. The main challenge of oral cancer prevention is to deal with the target groups' informational and cognitive barriers. PMID- 30296927 TI - Survival following rectal cancer surgery: does the age matter? AB - INTRODUCTION: Information regarding rectal cancer surgery outcomes and survival benefits in the elderly is sparse. Radical rectal surgery can be associated with substantial morbidity and mortality. We investigated age-specific survival for patients undergoing radical rectal surgery to determine outcomes in elderly patients Methods: Over a 10-year period data on all patients who underwent rectal cancer surgery was performed. Patients were grouped according to age and eight other variables including cancer stage (Duke's/TNM). Data analysed using computer program R. Kaplan-Meier survival curves estimated for age groups and compared using a modified log-rank permutation test. Survival curves fitted using Cox proportional hazard models and hazard ratios obtained Results: About 374 patients underwent surgery. Survival percentages at 1 year by age group are 91.3% for age <50, and 75.5% for age >80. At 5 years these are 87.0% for age <50 and 57.1% for >80. Overall the variation among the survival curves for the age groups is significant (p < .001). The hazard ratio for over the 80+ with the age group <50 as the reference is 4.79 (95% CI: 1.44-15.92) and is significant (p = .011) Conclusion: Overall survival is significantly less in the elderly. There is a striking reduction in survival in >80 year olds in the first post-operative year. This study highlights that care must be taken in deciding whether radical surgery should be offered to those patients and careful consideration is given to allow the best overall survival and quality of life. PMID- 30296928 TI - Student nurses' perceptions of FacebookTM as an interactive learning platform in nursing education. AB - BACKGROUND: The use of FacebookTM in nursing education is under-researched. OBJECTIVE: To assess students' perceptions of using FacebookTM as an educational mean to support their study. METHODS: One group pretest-posttest study was conducted in one nursing school in Jordan. FacebookTM pages were created for two nursing courses. Students completed a questionnaire about students' perception of using FacebookTM as educational platform in the first lecture of the semester as a pre-test, and then at the end of the semester as a post-test; after interacting with the created FacebookTM page. RESULTS: Students perceived that FacebookTM is an effective tool for nursing education (n = 119, 78.8%). It can facilitate the communication, ease access to course materials, and provide support for students. However, a few students believed that FacebookTM is a distraction from study, requires users to have special skills, and does not protect privacy. CONCLUSION: This preliminary evaluation revealed that FacebookTM can be used as an instructional tool to support nursing education. PMID- 30296929 TI - Successful Percutaneous Recanalization of a Chronically Occluded Inferior Vena Cava in a Young Child. AB - Young children with congenital heart disease are undergoing an increasing number of catheter-based interventions. These procedures can lead to obstruction of large central veins, making future interventions more challenging or even impossible. We present a young child with a chronically occluded inferior vena cava (IVC) secondary to prior catheterization-based interventions for congenital heart disease. The IVC was recanalized with serial angioplasty and stent placement with continued patency for over two years. Despite the long duration of obstruction, the IVC was successfully recanalized, eliminating the potential consequences of long-term IVC obstruction and making it easier for future catheter-based interventions, if needed. PMID- 30296930 TI - Stigma and the in(visible) perspectives and expectations of home oxygen therapy among people with chronic breathlessness syndrome: A qualitative study. AB - BACKGROUND: Chronic breathlessness syndrome in the context of advancing disease is distressing for all concerned. Oxygen is commonly prescribed in this setting; however, little is known about the perspectives of breathless people who either are on oxygen or are yet to have it prescribed. AIM: To understand and describe the perspectives and experiences of breathless people towards oxygen use at home. DESIGN: This qualitative study utilised an interpretive description approach using semi-structured interviews and thematic analysis. SETTING/PARTICIPANTS: A total of 19 people with chronic breathlessness syndrome living in South Australia participated in semi-structured interviews. Participants were divided into sub groups according to whether they were chronically breathless and (1) not using home oxygen ( n = 6), (2) using funded home oxygen for severe hypoxaemia ( n = 7) and (3) using home oxygen for palliation outside of funding guidelines ( n = 6). RESULTS: Three main themes were identified: (1) managing distress and living with chronic breathlessness syndrome, with or without oxygen, requires a range of self management strategies; (2) expectations of oxygen use: 'Not as good as I thought it would be'; and (3) the stigma of using oxygen: the visible and invisible. CONCLUSION: People living with chronic breathlessness struggle daily with both the progression of the underlying disease and the distressing nature of the syndrome. While oxygen does provide benefit for some people, its use and the perceptions of its use are often associated with both the visible and invisible manifestations of stigma. Clinicians need to promote self-management strategies and give careful thought to the prescribing of home oxygen, especially outside the current funding guidelines. PMID- 30296931 TI - Impact of dapagliflozin on left ventricular diastolic function of patients with type 2 diabetic mellitus with chronic heart failure. AB - BACKGROUND: The objective of this study was to investigate the impact of sodium glucose cotransporter type 2 (SGLT2) inhibitors on left ventricular (LV) diastolic function of type 2 diabetes mellitus (T2DM) patients with heart failure (HF). METHODS: This trial was a prospective multicenter study of 58 T2DM patients with stable HF at five institutions in Japan. Patients who had been taking at least one antidiabetic drugs other than SGLT2 inhibitors started the administration of 5 mg/day of dapagliflozin. The physical examinations, blood tests, and echocardiography were performed at baseline and 6 months after administration of dapagliflozin. The primary endpoint was defined as a change in mitral inflow E and mitral e' annular velocities (E/e') between baseline and 6 months after the administration of dapagliflozin. The secondary end points consisted of a change in brain natriuretic peptide (BNP), LV mass index (LVMI) and left atrial volume index (LAVI). RESULTS: E/e' significantly decreased from 9.3 to 8.5 cm/s (p = 0.020) 6 months after administration of dapagliflozin. LAVI and LVMI significantly decreased from 31 to 26 mL/m2 (p = 0.001), and from 75.0 to 67.0 g/m2 (p < 0.001), respectively, 6 months after administration of dapagliflozin. No significant change was observed in BNP (from 27.9 to 28.9 pg/mL; p = 0.132) 6 months after administration of dapagliflozin, except for a significant decrease from 168.8 to 114.3 pg/mL (p = 0.012) in patients with BNP >= 100 pg/mL. CONCLUSION: This prospective multicenter trial showed the beneficial effect of SGLT2 inhibitors on LV diastolic functional parameters for T2DM patients with HF. Our findings may thus offer a new insight into the management of T2DM patients.

PMID- 30296932 TI - First year experiences with a palliative out-patients structure for patients with COPD: a qualitative study of health professionals' expectations and experiences. AB - BACKGROUND: To improve the care of patients with advanced COPD and be able to address their palliative needs a new outpatient organization (CAPTAIN) was developed and implemented. CAPTAIN was inspired by best practice and existing guidelines and changed the traditional organization of an outpatient structure including the roles of nurses and doctors. Only sparse knowledge exists of the health professionals' expectations and experiences to organizational changes in an outpatient setting. This insight is necessary as health professionals are key stakeholders in implementing new structures and successfully transforming knowledge into practice. The aim of this study was to explore the health professionals' expectations and experiences of a new palliative out-patients structure for patients with advanced COPD. METHODS: The design was interpretive description as described by Thorne. Focus groups and individual interviews were conducted with pulmonary nurses, pulmonary doctors and municipality nurses from 2014 to 2016. RESULTS: The overall theme was dualism. Both nurses and doctors were pending between aspiration and concern in their expectations to the new structure, meanwhile their actual experiences were pending between perceived gain and improvements versus consequences with the new structure. Nurses' and doctors' existing practice was altered and the new structure required new ways for them to cooperate and ways in which skills from each profession were most efficiently utilized. CONCLUSION: Nurses and doctors considered the new structure as a quality boost and it fulfilled their hope of improving the quality of care offered to patients with advanced COPD, however with increased work-related stress as a derived consequence. PMID- 30296933 TI - A mixed-method evaluation of the views of medical teachers on the applicability of the 'infant and young child feeding chapter' in Saudi medical colleges. AB - BACKGROUND: Lack of sufficient preparation of physicians for the provision of breastfeeding support and counselling has been well-documented. The development of training in breastfeeding medicine for medical students is currently ongoing worldwide. This study was conducted to gain insights into a potential framework for a breastfeeding education curriculum. METHODS: A mixed-method design was used to evaluate the opinions of medical teachers regarding current lactation education and the applicability of the World Health Organization 'Infant and young child feeding: model chapter for textbooks for medical students and allied health professionals' in medical colleges in Riyadh, Saudi Arabia. Twelve teachers from three medical schools were invited to participate in three rounds of research. The first round was carried out through an interview using open ended questions under three headings: 1) The general opinion on breastfeeding medicine education in medical colleges; 2) The opinion on the contents of the chapter under investigation; and 3) The opinion on cultural points regarding Saudi Arabia and breastfeeding education in medical colleges. This was followed by a thematic analysis. Self-administered, closed-ended questionnaires were created for the second round based the results of the first round. The third round addressed areas of disagreement in opinions. To assess the degree of agreement objectively, rounds 2 and 3 were analyzed according to the 5-point Likert scale, with responses merged to a 3-point Likert scale where appropriate. A consensus was reached when greater than 70% agreement achieved. RESULTS: All participants agreed that breastfeeding education is suboptimal. Although they considered the world health organization resource on infant and young child chapter a suitable reference for the curriculum, they agreed that modifications to suit the Saudi Arabian context are necessary. The medical teachers suggested a unique curriculum for medical students, which is similar for both genders. However, disagreement existed regarding the provision of extra clinical training to female students. CONCLUSIONS: Breastfeeding medicine education in medical colleges should be developed using resources that are rich in content, are physician-specific and take into consideration the culture. PMID- 30296934 TI - Neurodevelopmental and emotional-behavioral outcomes in late-preterm infants: an observational descriptive case study. AB - BACKGROUND: Over the last decade, several studies investigated the outcomes in children born very preterm. Only recently there has been an increasing interest in the late preterm infants (born between 34 + 0 and 36 + 6 weeks). This population is at high risk of morbidity and mortality in the first years of life. Other studies reported that they are also at risk of long-term developmental problem. Therefore, the aim of this study is to describe the neurodevelopmental and emotional-behavioral outcome in a sample of late preterm patients. METHODS: The study included late preterm children and adolescents who had neuropsychiatric and/or neurological symptoms. They underwent a general, neurocognitive and an emotional-behavioral assessment. Exclusion criteria included: patients affected by Central Nervous System congenital abnormalities, neurodegenerative diseases, genetic disorders, epilepsy, or in pharmacological treatment, or adopted children. A descriptive statistics analysis was performed to describe the sociodemographic and clinical characteristics of patients. Risk factors related to late preterm birth, prevalence of neurodevelopmental disorders, and cognitive functioning were recorded and analyzed. RESULTS: The sample included 68 LPI (45 males and 23 females) aged from 2 to 16.3 years (mean age 7,5 years), who were affected by one or more neurodevelopmental disorder, including Language Disorder, Attention Deficit Hyperactivity Disorder, Specific Learning Disorder, Developmental Coordination Disorder, Intellectual Disability and Autism Spectrum Disorder. Moreover, in 30.8% of patients, internalizing problems (affective and social skills problem) were detected. CONCLUSIONS: Our results support the importance of a long-term surveillance of late preterm and the great need for more longitudinal large population studies in order to collect data on the neurodevelopmental outcomes of this population. PMID- 30296935 TI - Pathways to ensure universal and affordable access to hepatitis C treatment. AB - Direct-acting antivirals (DAAs) have dramatically changed the landscape of hepatitis C treatment and prevention. The World Health Organization has called for the elimination of hepatitis C as a public health threat by 2030. However, the discrepancy in DAA prices across low-, middle- and high-income countries is considerable, ranging from less than US$ 100 to approximately US$ 40,000 per course, thus representing a major barrier for the scale-up of treatment and elimination. This article describes DAA pricing and pathways to accessing affordable treatment, providing case studies from Australia, Egypt and Portugal. Pathways to accessing DAAs include developing comprehensive viral hepatitis plans to facilitate price negotiations, voluntary and compulsory licenses, patent opposition, joint procurement, and personal importation schemes. While multiple factors influence the price of DAAs, a key driver is a country's capacity and willingness to negotiate with pharmaceutical companies. If negotiations do not lead to a reasonable price, governments have the option to utilise flexibilities outlined in the Agreement on Trade-Related Aspects of Intellectual Property Rights. Affordable access to DAAs is underpinned by collaboration between government, civil society, global organisations and pharmaceutical companies to ensure that all patients can access treatment. Promoting these pathways is critical for influencing policy, improving access to affordable DAAs and achieving hepatitis C elimination. PMID- 30296936 TI - The effects of coenzyme Q10 supplementation on lipid profiles among patients with coronary artery disease: a systematic review and meta-analysis of randomized controlled trials. AB - BACKGROUND: Chronic inflammation and increased oxidative stress significantly contribute in developing coronary artery disease (CAD). Hence, antioxidant supplementation might be an appropriate approach to decrease the incidence of CAD. This systematic review and meta-analysis was aimed to determine the effects of coenzyme Q10 (CoQ10) supplementation on lipid profile, as one of the major triggers for CAD, among patients diagnosed with coronary artery disease. METHODS: EMBASE, Scopus, PubMed, Cochrane Library, and Web of Science were searched for studies prior to May 20th, 2018. Cochrane Collaboration risk of bias tool was applied to assess the methodological quality of included trials. I-square and Q tests were used to measure the existing heterogeneity across included studies. Considering heterogeneity among studies, fixed- or random-effect models were applied to pool standardized mean differences (SMD) as overall effect size. RESULTS: A total of eight trials (267 participants in the intervention group and 259 in placebo group) were included in the current meta-analysis. The findings showed that taking CoQ10 by patients with CAD significantly decreased total cholesterol (SMD -1.07; 95% CI, - 1.94, - 0.21, P = 0.01) and increased HDL cholesterol levels (SMD 1.30; 95% CI, 0.20, 2.41, P = 0.02). We found no significant effects of CoQ10 supplementation on LDL-cholesterol (SMD -0.37; 95% CI, - 0.87, 0.13, P = 0.14), lipoprotein (a) [Lp(a)] levels (SMD -1.12; 95% CI, - 2.84, 0.61, P = 0.20) and triglycerides levels (SMD 0.01; 95% CI, - 0.22, 0.24, P = 0.94). CONCLUSIONS: This meta-analysis demonstrated the promising effects of CoQ10 supplementation on lowering lipid levels among patients with CAD, though it did not affect triglycerides, LDL-cholesterol and Lp(a) levels. PMID- 30296937 TI - Restoration of biofuel production levels and increased tolerance under ionic liquid stress is enabled by a mutation in the essential Escherichia coli gene cydC. AB - BACKGROUND: Microbial production of chemicals from renewable carbon sources enables a sustainable route to many bioproducts. Sugar streams, such as those derived from biomass pretreated with ionic liquids (IL), provide efficiently derived and cost-competitive starting materials. A limitation to this approach is that residual ILs in the pretreated sugar source can be inhibitory to microbial growth and impair expression of the desired biosynthetic pathway. RESULTS: We utilized laboratory evolution to select Escherichia coli strains capable of robust growth in the presence of the IL, 1-ethyl-3-methyl-imidizolium acetate ([EMIM]OAc). Whole genome sequencing of the evolved strain identified a point mutation in an essential gene, cydC, which confers tolerance to two different classes of ILs at concentrations that are otherwise growth inhibitory. This mutation, cydC-D86G, fully restores the specific production of the bio-jet fuel candidate D-limonene, as well as the biogasoline and platform chemical isopentenol, in growth medium containing ILs. Similar amino acids at this position in cydC, such as cydC-D86V, also confer tolerance to [EMIM]OAc. We show that this [EMIM]OAc tolerance phenotype of cydC-D86G strains is independent of its wild-type function in activating the cytochrome bd-I respiratory complex. Using shotgun proteomics, we characterized the underlying differential cellular responses altered in this mutant. While wild-type E. coli cannot produce detectable amounts of either product in the presence of ILs at levels expected to be residual in sugars from pretreated biomass, the engineered cydC-D86G strains produce over 200 mg/L D-limonene and 350 mg/L isopentenol, which are among the highest reported titers in the presence of [EMIM]OAc. CONCLUSIONS: The optimized strains in this study produce high titers of two candidate biofuels and bioproducts under IL stress. Both sets of production strains surpass production titers from other IL tolerant mutants in the literature. Our application of laboratory evolution identified a gain of function mutation in an essential gene, which is unusual in comparison to other published IL tolerant mutants.

AB - Spatial mapping of genomic data to tissue context in a high-throughput and high resolution manner has been challenging due to technical limitations. Here, we describe PHLI-seq, a novel approach that enables high-throughput isolation and genome-wide sequence analysis of single cells or small numbers of cells to construct genomic maps within cancer tissue in relation to the images or phenotypes of the cells. By applying PHLI-seq, we reveal the heterogeneity of breast cancer tissues at a high resolution and map the genomic landscape of the cells to their corresponding spatial locations and phenotypes in the 3D tumor mass. PMID- 30296940 TI - CRISPhieRmix: a hierarchical mixture model for CRISPR pooled screens. AB - Pooled CRISPR screens allow researchers to interrogate genetic causes of complex phenotypes at the genome-wide scale and promise higher specificity and sensitivity compared to competing technologies. Unfortunately, two problems exist, particularly for CRISPRi/a screens: variability in guide efficiency and large rare off-target effects. We present a method, CRISPhieRmix, that resolves these issues by using a hierarchical mixture model with a broad-tailed null distribution. We show that CRISPhieRmix allows for more accurate and powerful inferences in large-scale pooled CRISPRi/a screens. We discuss key issues in the analysis and design of screens, particularly the number of guides needed for faithful full discovery. PMID- 30296941 TI - Food perception without ingestion leads to metabolic changes and irreversible developmental arrest in C. elegans. AB - BACKGROUND: Developmental physiology is very sensitive to nutrient availability. For instance, in the nematode Caenorhabditis elegans, newly hatched L1-stage larvae require food to initiate postembryonic development. In addition, larvae arrested in the dauer diapause, a non-feeding state of developmental arrest that occurs during the L3 stage, initiate recovery when exposed to food. Despite the essential role of food in C. elegans development, the contribution of food perception versus ingestion on physiology has not been delineated. RESULTS: We used a pharmacological approach to uncouple the effects of food (bacteria) perception and ingestion in C. elegans. Perception was not sufficient to promote postembryonic development in L1-stage larvae. However, L1 larvae exposed to food without ingestion failed to develop upon return to normal culture conditions, instead displaying an irreversible arrest phenotype. Inhibition of gene expression during perception rescued subsequent development, demonstrating that the response to perception without feeding is deleterious. Perception altered DAF 16/FOXO subcellular localization, reflecting activation of insulin/IGF signaling (IIS). The insulin-like peptide daf-28 was specifically required, suggesting perception in chemosensory neurons, where it is expressed, regulates peptide synthesis and possibly secretion. However, genetic manipulation of IIS did not modify the irreversible arrest phenotype caused by food perception, revealing that wild-type function of the IIS pathway is not required to produce this phenotype and that other pathways affected by perception of food in the absence of its ingestion are likely to be involved. Gene expression and Nile red staining showed that food perception could alter lipid metabolism and storage. We found that starved larvae sense environmental polypeptides, with similar molecular and developmental effects as perception of bacteria. Environmental polypeptides also promoted recovery from dauer diapause, suggesting that perception of polypeptides plays an important role in the life history of free-living nematodes. CONCLUSIONS: We conclude that actual ingestion of food is required to initiate postembryonic development in C. elegans. We also conclude that polypeptides are perceived as a food-associated cue in this and likely other animals, initiating a signaling and gene regulatory cascade that alters metabolism in anticipation of feeding and development, but that this response is detrimental if feeding does not occur. PMID- 30296942 TI - CRISPR-mediated deletion of prostate cancer risk-associated CTCF loop anchors identifies repressive chromatin loops. AB - BACKGROUND: Recent genome-wide association studies (GWAS) have identified more than 100 loci associated with increased risk of prostate cancer, most of which are in non-coding regions of the genome. Understanding the function of these non coding risk loci is critical to elucidate the genetic susceptibility to prostate cancer. RESULTS: We generate genome-wide regulatory element maps and performed genome-wide chromosome confirmation capture assays (in situ Hi-C) in normal and tumorigenic prostate cells. Using this information, we annotate the regulatory potential of 2,181 fine-mapped prostate cancer risk-associated SNPs and predict a set of target genes that are regulated by prostate cancer risk-related H3K27Ac mediated loops. We next identify prostate cancer risk-associated CTCF sites involved in long-range chromatin loops. We use CRISPR-mediated deletion to remove prostate cancer risk-associated CTCF anchor regions and the CTCF anchor regions looped to the prostate cancer risk-associated CTCF sites, and we observe up to 100-fold increases in expression of genes within the loops when the prostate cancer risk-associated CTCF anchor regions are deleted. CONCLUSIONS: We identify GWAS risk loci involved in long-range loops that function to repress gene expression within chromatin loops. Our studies provide new insights into the genetic susceptibility to prostate cancer. PMID- 30296943 TI - Usefulness of carotid ultrasonography in the diagnosis of coronary artery disease in patients undergoing exercise echocardiography. AB - BACKGROUND: Relationship between carotid and coronary artery disease (CAD) in patients undergoing invasive and non-invasive test is unclear. The aim of the study is to evaluate whether carotid disease is associated with CAD in patients submitted to exercise echocardiography (EE) and if it improves the EE ability to predict CAD. METHODS: We retrospectively studied 156 subjects without previous vascular disease who underwent EE, carotid ultrasonography and coronary angiography between 2002 and 2013. Positive EE was defined as exercise induced wall motion abnormalities, carotid disease according to Manheim and American Society of Echocardiography Consensus and significant CAD as stenosis >=50%. RESULTS: Eighty-nine (57.1%) subjects had significant CAD. Factors associated with CAD in multivariate analysis were fasting plasma glucose (odds ratio [OR] 1.02, p = 0.031), pre-test probability of CAD > 65% (OR 3.71, p < 0.001), positive EE (OR 10.51, p < 0.001) and carotid plaque (CP) presence (OR 2.95, p = 0.013). There was neither statistical significant difference in area under the curve after addition of CP to EE results (0.77 versus 0.81, p = 0.525) nor sensitivity, specificity, predictive values or efficiency. CP presence reclassified as very high-risk according to Systematic COronary Risk Evaluation 13 patients (34.2%) with negative EE and 22 (33.3%) without CAD. CONCLUSION: CP is associated with CAD in patients undergoing EE, however its addition to EE does not improve CAD prediction, probably due to insufficient statistical power. CP reclassified one third of patients to very high-risk category despite negative EE or CAD absence, these subjects benefit from aggressive primary prevention interventions. PMID- 30296944 TI - Description of a novel RyR2 mutation in a juvenile patient with symptomatic catecholaminergic polymorphic ventricular tachycardia in sleep and during exercise: a case report. AB - BACKGROUND: Catecholaminergic polymorphic ventricular tachycardia is an inherited disease presenting with arrhythmic events during physical exercise or emotional stress. If untreated, catecholaminergic polymorphic ventricular tachycardia is a highly lethal condition: About 80% of affected individuals experience recurrent syncope, and 30% experience cardiac arrest. Catecholaminergic polymorphic ventricular tachycardia is caused by mutations in genes encoding ryanodine receptor type 2 (RyR2) and cardiac calsequestrin (CASQ2). In cases of sympathoadrenergic activation, both mutations result in a spontaneous Ca2+ release in cardiac cells, facilitating ventricular arrhythmias. CASE PRESENTATION: We present a case of a 17-year-old Caucasian boy who survived sudden cardiac death caused by ventricular fibrillation while performing running exercise in a fitness center. The diagnostic workup included blood tests, coronary angiography, electrophysiological testing, and cardiac magnetic resonance imaging, but all results were normal. Because the patient's medical history included recurrent syncope during physical and emotional stress, we strongly suspected catecholaminergic polymorphic ventricular tachycardia as the underlying disease. Genetic screening was performed and confirmed the diagnosis, revealing a new heterozygous point mutation in the gene for RyR2, c.12520T>A (p.F4174 l, exon 90, RyR2 gene). The patient was discharged from our hospital after undergoing implantation of an implantable cardioverter defibrillator for secondary prevention. Shortly after implantation, the implantable cardioverter defibrillator terminated a sustaining ventricular tachycardia episode by antitachycardic pacing. This episode occurred early in the morning while the patient was asleep. CONCLUSIONS: We present a case of catecholaminergic polymorphic ventricular tachycardia associated with a novel single point mutation in the RyR2 gene, which, to the best of our knowledge, has not been described in the literature so far. Our patient experienced arrhythmic events under both resting conditions and physical activity, an uncommon finding in patients with catecholaminergic polymorphic ventricular tachycardia. This novel mutation may cause arrhythmias independent of sympathoadrenergic stimulation, but further evidence is needed to prove causality.

PMID- 30296945 TI - Should anti-EGFR mAbs be discontinued for conversion surgery in untreated right sided metastatic colorectal cancer? A systematic review and meta-analysis. AB - BACKGROUND: Previous studies have demonstrated that left-sided tumors have better prognoses than right-sided tumors in RAS wild-type mCRC (metastatic colorectal cancer) patients, while anti-EGFR mAbs appear to have no advantage compared with bevacizumab for right-sided tumors in these patients. Nevertheless, it remains unclear whether primary tumor location affects patients' options for potentially curative resection. METHODS: PubMed, the Cochrane Library, Embase, ASCO, and ESMO conference abstracts were searched. The inclusion criteria were RCT (randomized controlled trials) studies that evaluated the efficacy of anti-EGFR mAbs based on primary tumor location. The outcomes included ORR, ETS, and DpR. ORs for ORR were calculated with 95% confidence intervals by Comprehensive Meta-Analysis, version 2.0. RESULT: Nine studies including nine RCTs were analyzed. Regardless of left- or right-sided tumors, the ORRs for anti-EGFR mAb (left-sided: 80.2%, 95% CI, 47 95%; I2 = 76.9%; right-sided: 46.1%, 95% CI, 39.4-53.0%; I2 = 18.9%) were both higher than the control arm including chemotherapy with or without bevacizumab. The ORs for anti-EGFR mAbs have a significant benefit compared with chemotherapy with or without bevacizumab in left-sided tumors (OR = 2.19, 95% CI, 1.41-3.38; P < 0.001). For right-sided tumors, anti-EGFR mAbs still significantly improved the ORR compared with chemotherapy alone (OR = 1.75, 95% CI, 1.05-2.90; P = 0.03), and the OR numerically favored the anti-EGFR mAbs compared with bevacizumab (OR = 1.281, 95% CI, 0.77-2.12; P = 0.335). The data of ETS and DpR from three RCTs also favored the EGFR antibody irrespective of tumor location. Resection data on differentiating tumor locations is inconclusive. For right-sided tumors, it should be noted that median PFS and OS were comparable for patients who achieved ETS in both treatment arms. CONCLUSIONS: Anti-EGFR mAbs have advantages in the tumor shrinkage regardless of left- or right-sided tumors, which is important for conversion therapy. For right-sided tumors, anti-EGFR mAbs should remain the first choice for potentially curative resection in RAS wild-type mCRC patients. ETS may represent a subgroup of patients with right-sided tumors who might benefit from the anti-EGFR mAb. PMID- 30296947 TI - Effects of social defeat stress on dopamine D2 receptor isoforms and proteins involved in intracellular trafficking. AB - BACKGROUND: Chronic social defeat stress induces depression and anxiety-like behaviors in rodents and also responsible for differentiating defeated animals into stress susceptible and resilient groups. The present study investigated the effects of social defeat stress on a variety of behavioral parameters like social behavior, spatial learning and memory and anxiety like behaviors. Additionally, the levels of various dopaminergic markers, including the long and short form of the D2 receptor, and total and phosphorylated dopamine and cyclic adenosine 3',5' monophosphate regulated phosphoprotein-32, and proteins involved in intracellular trafficking were assessed in several key brain regions in young adult mice. METHODS: Mouse model of chronic social defeat was established by resident intruder paradigm, and to evaluate the effect of chronic social defeat, mice were subjected to behavioral tests like spontaneous locomotor activity, elevated plus maze (EPM), social interaction and Morris water maze tests. RESULTS: Mice were divided into susceptible and unsusceptible groups after 10 days of social defeat stress. The susceptible group exhibited greater decreases in time spent in the open and closed arms compared to the control group on the EPM. In the social interaction test, the susceptible group showed greater increases in submissive and neutral behaviors and greater decreases in social behaviors relative to baseline compared to the control group. Furthermore, increased expression of D2L, D2S, Rab4, and G protein-coupled receptor associated sorting protein-1 was observed in the amygdala of the susceptible group compared to the control group. CONCLUSION: These findings suggest that social defeat stress induce anxiety-like and altered social interacting behaviors, and changes in dopaminergic markers and intracellular trafficking-related proteins. PMID- 30296948 TI - A gaze-independent audiovisual brain-computer Interface for detecting awareness of patients with disorders of consciousness. AB - BACKGROUND: Currently, it is challenging to detect the awareness of patients who suffer disorders of consciousness (DOC). Brain-computer interfaces (BCIs), which do not depend on the behavioral response of patients, may serve for detecting the awareness in patients with DOC. However, we must develop effective BCIs for these patients because their ability to use BCIs does not as good as healthy users. METHODS: Because patients with DOC generally do not exhibit eye movements, a gaze independent audiovisual BCI is put forward in the study where semantically congruent and incongruent audiovisual number stimuli were sequentially presented to evoke event-related potentials (ERPs). Subjects were required to pay attention to congruent audiovisual stimuli (target) and ignore the incongruent audiovisual stimuli (non-target). The BCI system was evaluated by analyzing online and offline data from 10 healthy subjects followed by being applied to online awareness detection in 8 patients with DOC. RESULTS: According to the results on healthy subjects, the audiovisual BCI system outperformed the corresponding auditory-only and visual-only systems. Multiple ERP components, including the P300, N400 and late positive complex (LPC), were observed using the audiovisual system, strengthening different brain responses to target stimuli and non-target stimuli. The results revealed the abilities of three of eight patients to follow commands and recognize numbers. CONCLUSIONS: This gaze-independent audiovisual BCI system represents a useful auxiliary bedside tool to detect the awareness of patients with DOC. PMID- 30296950 TI - ETHICS IN HEALTH TECHNOLOGY ASSESSMENT: A SYSTEMATIC REVIEW. AB - OBJECTIVES: Integration of ethics into health technology assessment (HTA) remains challenging for HTA practitioners. We conducted a systematic review on social and methodological issues related to ethical analysis in HTA. We examined: (1) reasons for integrating ethics (social needs); (2) obstacles to ethical integration; (3) concepts and processes deployed in ethical evaluation (more specifically value judgments) and critical analyses of formal experimentations of ethical evaluation in HTA. METHODS: Search criteria included "ethic," "technology assessment," and "HTA". The literature search was done in Medline/Ovid, SCOPUS, CINAHL, PsycINFO, and the international HTA Database. Screening of citations, full-text screening, and data extraction were performed by two subgroups of two independent reviewers. Data extracted from articles were grouped into categories using a general inductive method. RESULTS: A list of 1,646 citations remained after the removal of duplicates. Of these, 132 were fully reviewed, yielding 67 eligible articles for analysis. The social need most often reported was to inform policy decision making. The absence of shared standard models for ethical analysis was the obstacle to integration most often mentioned. Fairness and Equity and values embedded in Principlism were the values most often mentioned in relation to ethical evaluation. CONCLUSIONS: Compared with the scientific experimental paradigm, there are no settled proceedings for ethics in HTA nor consensus on the role of ethical theory and ethical expertise hindering its integration. Our findings enable us to hypothesize that there exists interdependence between the three issues studied in this work and that value judgments could be their linking concept. PMID- 30296949 TI - Engineering of glycerol utilization in Gluconobacter oxydans 621H for biocatalyst preparation in a low-cost way. AB - BACKGROUND: Whole cells of Gluconobacter oxydans are widely used in various biocatalytic processes. Sorbitol at high concentrations is commonly used in complex media to prepare biocatalysts. Exploiting an alternative process for preparation of biocatalysts with low cost substrates is of importance for industrial applications. RESULTS: G. oxydans 621H was confirmed to have the ability to grow in mineral salts medium with glycerol, an inevitable waste generated from industry of biofuels, as the sole carbon source. Based on the glycerol utilization mechanism elucidated in this study, the major polyol dehydrogenase (GOX0854) and the membrane-bound alcohol dehydrogenase (GOX1068) can competitively utilize glycerol but play no obvious roles in the biocatalyst preparation. Thus, the genes related to these two enzymes were deleted. Whole cells of G. oxydans ?GOX1068?GOX0854 can be prepared from glycerol with a 2.4 fold higher biomass yield than that of G. oxydans 621H. Using whole cells of G. oxydans ?GOX1068?GOX0854 as the biocatalyst, 61.6 g L-1 xylonate was produced from 58.4 g L-1 xylose at a yield of 1.05 g g-1. CONCLUSION: This process is an example of efficient preparation of whole cells of G. oxydans with reduced cost. Besides xylonate production from xylose, other biocatalytic processes might also be developed using whole cells of metabolic engineered G. oxydans prepared from glycerol. PMID- 30296951 TI - Performing and analysing tone-induced cervical and ocular vestibular-evoked myogenic potentials in traumatic and non-traumatic vestibular pathology. AB - OBJECTIVE: This paper discusses our technique of carrying out cervical and ocular vestibular-evoked myogenic potential testing in a single position. The described technique allows for a symmetrical, natural flexion of the neck muscles, which is helpful as many of our patients have suffered traumatic deceleration injures. METHODS: Patients with suspected vestibular pathology referred by specialists were sequentially assessed in a tertiary referral neuro-otology unit within a teaching hospital using our technique and our previously established normative database. All patients underwent standardised vestibular assessment in addition to cervical and ocular vestibular-evoked myogenic potential assessment. Our normative data are in keeping with that reported by other centres. RESULTS: Many of the patients had abnormal vestibular-evoked myogenic potentials, which is in line with a history suggesting otolithic disease. CONCLUSION: Both cervical and ocular vestibular-evoked myogenic potentials offer several parameters for detecting abnormalities. The technique reported enables us to assess patients in an accurate fashion whether or not they have suffered traumatic neck injuries. PMID- 30296952 TI - Experiencing syndemic: disentangling the biosocial complexity of tuberculosis through qualitative research. AB - Tuberculosis (TB) remains a major global public health problem that has become a crisis fuelled by HIV and the increasing occurrence of antimicrobial resistance. What has been termed the biosocial nature of TB challenges effective control of the disease. Yet, biosocial interactions involved in the persistence of TB in diverse settings are difficult to systematically account for. The recently developed framework of syndemics provides a way to capture how complex health problems result from the interactions between diseases such as HIV and TB, and harmful social conditions such as unemployment, malnutrition and substance abuse. This article advances the syndemics scholarship by examining health conditions that cluster together with TB in the Russian Federation, by eliciting a set of social processes that precipitate this clustering and exacerbate health outcomes, and by analysing interactions between these health conditions and social processes. To provide an account of this complexity, the article takes a qualitative approach and draws on the perspectives and experiences of people with TB. The results demonstrate emergence of a syndemic of stress, substance abuse, TB and HIV that is sustained by poverty, occupational insecurity, marginalization and isolation. Frictions between the narrow focus of the health care system on TB and the wider syndemic processes in which the lives of many persons with TB are embedded, contribute to poorer health outcomes and increase the risks of developing drug resistance. Finally, the article argues that the large-scale and impersonal forces become embodied as individual pathology through the crucial interface of the ways in which persons experience and make sense of these forces and pathologies. Qualitative research is needed for the adequate analysis of this biosocial complexity in order to provide a solid basis for responses to TB centred syndemics in various settings. PMID- 30296953 TI - Peritonsillar infiltration of lidocaine with adrenaline is associated with increased risk of secondary post-tonsillectomy haemorrhage. AB - OBJECTIVES: In order to evaluate the safety of tonsillectomy among children, we retrospectively studied the incidence of post-operative complications, adverse events and their association with peri-operative medication. METHODS: Data were collected from the medical records of 691 patients aged 1-16 years, including details of post-operative complications (any unplanned contact with the hospital), analgesics, dexamethasone, 5-HT3 antagonists, local anaesthetic and haemostatic agents. RESULTS: Recovery was complicated in 13.6 per cent of patients, of whom 8.4 per cent were re-admitted to the ward. The most common complication was post-tonsillectomy haemorrhage, experienced by 7.1 per cent of patients. Re-operation under general anaesthesia (for grade III post tonsillectomy haemorrhage) was required by 4.2 per cent of patients. Peritonsillar infiltration of lidocaine with adrenaline increased the risk of post-tonsillectomy haemorrhage (odds ratio = 4.1; 95 per cent confidence interval = 2.1 to 8.3). CONCLUSION: Every seventh paediatric patient experienced a complicated recovery after tonsillectomy, caused by post-tonsillectomy haemorrhage in most cases. Local peritonsillar infiltration of lidocaine with adrenaline was associated with an increased risk of post-tonsillectomy haemorrhage. PMID- 30296954 TI - COST-EFFECTIVENESS OF INTERVENTIONS BASED ON PHYSICAL ACTIVITY IN THE TREATMENT OF CHRONIC CONDITIONS: A SYSTEMATIC LITERATURE REVIEW. AB - OBJECTIVES: The aim of this study is to review evidence on the cost-effectiveness of exercise-based interventions in the treatment of chronic conditions a decade after the publication of Roine et al. in 2009 (Roine E, Roine RP, Rasanen P, et al. Int J Technol Assess Health Care. 2009;25:427-454). METHODS: We carried out a review of published articles in PUBMED and JSTOR between January 1, 2008, and December 31, 2016. Full economic evaluations of exercise programs targeting patients with a chronic condition were eligible for inclusion. Data on program, design, and economic characteristics were extracted using a predefined extraction form. The quality of the economic evaluations was appraised using the adjusted Consensus Health Economic Criteria List. RESULTS: A total of 426 articles were identified and thirty-seven studies were selected. Eleven studies dealt with musculoskeletal and rheumatologic disorders, ten with cardiovascular diseases, six with neurological disorders, three with mental illnesses, three with cancers, and four with diabetes, respiratory diseases, or pelvic organ prolapse. In total, 60 percent of exercise programs were dominant or cost-effective. For musculoskeletal and rheumatologic disorders, 72 percent of programs were dominant or cost-effective while this was the case for 57 percent of programs for cardiovascular diseases using a nonsurgical comparator. CONCLUSIONS: There is clear evidence in favor of exercise-based programs for the treatment of musculoskeletal and rheumatologic disorders and, to a lesser extent, for the treatment of cardiovascular diseases. More research is needed to evaluate the cost-effectiveness of physical activity in the treatment of neurological disorders, mental illnesses, cancers, respiratory diseases, and diabetes/obesity. PMID- 30296955 TI - Associations of birth characteristics with perimenopausal disorders: a prospective cohort study. AB - Perimenopausal disorders (PDs) are prevalent and importantly affect quality of life among middle-aged women. Yet, very little is known about the developmental origins of these disorders. The objective of this study was to investigate the associations of birth characteristics with PDs. This cohort study is based on archived birth records for birth weight and gestational age, and followed prospectively in Swedish inpatient and outpatient registers for 8 years (n=3212). The main outcomes were menopausal and climacteric states (e.g. flushing, sleeplessness), perimenopausal bleeding and other PDs (e.g. atrophic vaginitis). Cox proportional hazards regression models were used to estimate the hazard ratios (HRs) for three subtypes of PDs separately. During the follow-up, 218 women had PDs, among whom 125 had menopausal and climacteric states, 61 had perimenopausal bleeding and 58 had other PDs as first recorded disorder. Birth weight was linearly associated with incidence rate of menopausal and climacteric states [HR=1.66 per 1 kg increase, 95% confidence interval (95% CI)=1.14-2.41]. Gestational age (rather than birth weight) was associated with incidence rate of other PDs (HR=0.87 per 1 week increase, 95% CI=0.79-0.95). Neither birth weight nor gestational age was associated with perimenopausal bleeding. Similar results were found after adjustment for other early-life and adult socio-demographic characteristics. This observational study provides, for the first time, evidence regarding the developmental origins of PDs. Future research is required to investigate the underlying causal mechanisms, which may shed further light on the etiology of this class of disorders. PMID- 30296956 TI - Acceptable Limitations on Paramedic Duty to Treat During Disaster: A Qualitative Exploration. AB - : IntroductionThe Australian prehospital profession has not yet facilitated a comprehensive discussion regarding paramedic role and responsibility during disasters. Whether paramedics have a duty to treat under extreme conditions and what acceptable limitations may be placed on such a duty require urgent consideration. The purpose of this research is to encourage discussion within the paramedic profession and broader community on this important ethical and legal issue. METHODS: The authors employed qualitative methods to gather paramedic and community member perspectives in Victoria, Australia. RESULTS: These findings suggested that both paramedic and community member participants agree that acceptable limitations on paramedic duty to treat during disaster are required. These limitations should be based on consideration of the following factors: personal health circumstances (eg, pregnancy for female paramedics); pre-existing mental health conditions (eg, posttraumatic stress disorder/PTSD); competing personal obligations (eg, paramedics who are single parents); and unacceptable levels of personal risk (eg, risk of exposure and infection during a pandemic). CONCLUSION: It is only with the engagement of a more broadly representative segment of the prehospital profession and greater Australian community that appropriate guidance on limiting standards of care under extreme conditions can be developed and integrated within prehospital care in Australia.

AB - : ABSTRACTObjectives:Dance interventions are pleasant social activities that are often offered to people with dementia in care settings. Effectiveness of dance as a psychosocial intervention for people with dementia has been studied to some extent, but several methodological issues remain unexplored. This review aimed to analyze studies on dance interventions for people with dementia and to identify practice recommendations for the development of these interventions. METHODS: An electronic database search was run in December 2017 to identify records of dance interventions for people with dementia. We included all studies regardless of experimental design. Selected records were analyzed according to five criteria: study design and intentions of interventions; profile of participants and in/exclusion criteria; treatment indications and contraindications; description and performance of the interventions; and involved physical, cognitive, psychological, and social processes in dance. RESULTS: Fourteen records were included in which various study designs were observed. Description and performance of the interventions were well documented. Nine practice recommendations for implementing dance interventions were identified according to primary intentions of the intervention (therapeutic or recreational): indications; contra-indications; participant profile; dosage; session sequencing; setting of intervention; observance/attendance; contributors and facilitators;and assessments. CONCLUSIONS: Dance is a holistic intervention that can be implemented with a therapeutic or a leisure intention. Practice recommendations about dance interventions remain incomplete and insufficiently studied. Such recommendations could be helpful for clinicians to implement dance interventions in facilities where they work to better target people who could benefit from them, and for researchers to develop research in this field. PMID- 30296958 TI - The Impact of Irrational Beliefs on Paranoid Thoughts. AB - BACKGROUND: Although the ABC model proposed by cognitive behavioral theory has strong empirical support for a wide range of psychological problems, little is known about the role of irrational beliefs (IBs), a central concept of the ABC model, in the aetiology of paranoid thoughts, one of the most common psychotic symptoms. AIMS: The present study aimed to investigate the impact of IBs on paranoid thoughts and people's perceptions of others. METHOD: Eighty-one non clinical participants (m age = 21.21 years, SD = 2.72, range 18-33; 83.95% female) recruited for this study were randomly assigned to one of the two conditions: IBs or rational beliefs (RBs). In a role-play paradigm, subjects were asked to imagine holding a list of IBs or RBs, respectively, while being exposed to a neutral social context in a virtual reality environment. RESULTS: In line with the ABC model, results indicate that IBs lead to significantly higher levels of state paranoid thoughts and more negative perceptions of others than RBs, even after controlling for participants' baseline irrationality and trait paranoia [F (5,68) = 11.23, p < .001, Wilk's lambda = .54, partial eta2 = .45]. CONCLUSIONS: The findings of this paper suggest that IBs might play an aetiological role in the occurrence of paranoid thoughts. Practical and theoretical implications of these results are also considered. PMID- 30296959 TI - Improvement of gram-negative susceptibility to fluoroquinolones after implementation of a pre-authorization policy for fluoroquinolone use: A decade long experience. AB - OBJECTIVE: Due to concerns over increasing fluoroquinolone (FQ) resistance among gram-negative organisms, our stewardship program implemented a preauthorization use policy. The goal of this study was to assess the relationship between hospital FQ use and antibiotic resistance. DESIGN: Retrospective cohort. SETTING: Large academic medical center. METHODS: We performed a retrospective analysis of FQ susceptibility of hospital isolates for 5 common gram-negative bacteria: Acinetobacter spp., Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Primary endpoint was the change of FQ susceptibility. A Poisson regression model was used to calculate the rate of change between the preintervention period (1998-2005) and the postimplementation period (2006-2016). RESULTS: Large rates of decline of FQ susceptibility began in 1998, particularly among P. aeruginosa, Acinetobacter spp., and E. cloacae. Our FQ restriction policy improved FQ use from 173 days of therapy (DOT) per 1,000 patient days to <60 DOT per 1,000 patient days. Fluoroquinolone susceptibility increased for Acinetobacter spp. (rate ratio [RR], 1.038; 95% confidence interval [CI], 1.005-1.072), E. cloacae (RR, 1.028; 95% CI, 1.013-1.044), and P. aeruginosa (RR, 1.013; 95% CI, 1.006-1.020). No significant change in susceptibility was detected for K. pneumoniae (RR, 1.002; 95% CI, 0.996-1.008), and the susceptibility for E. coli continued to decline, although the decline was not as steep (RR, 0.981; 95% CI, 0.975-0.987). CONCLUSIONS: A stewardship-driven FQ restriction program stopped overall declining FQ susceptibility rates for all species except E. coli. For 3 species (ie, Acinetobacter spp, E. cloacae, and P. aeruginosa), susceptibility rates improved after implementation, and this improvement has been sustained over a 10-year period. PMID- 30296960 TI - Assessment of the knowledge of Brazilian Community Health Workers regarding prenatal care. AB - : AimTo evaluate prenatal care knowledge of Brazilian community health workers (CHWs). BACKGROUND: Routine prenatal care is critical for reducing health risks in women and their children. One of the responsibilities of primary healthcare providers is the provision of prenatal care. The CHWs, with their frequent contact with populations, work to improve health outreach efforts and therefore may be key role players in prenatal care. METHODS: This was a cross-sectional study. A questionnaire was developed to ascertain the degree of knowledge regarding prenatal care of CHWs, including: (1) general responsibilities of CHWs; (2) the initial contact with a pregnant woman; (3) examinations and vaccinations recommended for pregnant women; (4) pregnancy complications and signs of labor; and (5) lifestyle considerations for pregnant women. Responses were categorized into levels for knowledge. Demographic data were also collected. Descriptive analyses were conducted. Proportions of subjects with different levels of knowledge were compared according to each demographic variable, separately for each block of knowledge, using the chi 2 and Fisher's exact tests.FindingsIn total, 194 CHWs were interviewed. Overall, the majority of the CHWs presented high levels of knowledge in blocks 1 (43%), 2 (59%) and 5 (83%). However, in block 3 the proportions of subjects with high levels of knowledge regarding examinations and vaccinations were 35 and 40%, respectively. Only 24% of the participants presented a high level of knowledge in block 4. Stratified data analyses suggest that females were statistically more likely to have high levels of knowledge, whereas no statistically significant differences were found for the other demographic variables. Health services are already routinely using the questionnaire. CONCLUSION: The results suggest that CHWs, especially female CHWs, have an important role in assisting pregnant women in the community. The study indicates the areas of knowledge that require more specific attention from training providers. PMID- 30296961 TI - Monitoring the Health of Public Health Responders: Development and Use of the Responder Safety, Tracking, and Resilience System (R-STaR) for Hurricane Matthew. AB - ABSTRACTOn October 7, 2016, Hurricane Matthew traveled along the coasts of Florida, Georgia, and South Carolina causing flooding and power outages. The Georgia Department of Public Health (DPH) developed the Web-based Responder Safety, Tracking, and Resilience (R-STaR) system to monitor the health and safety of public health responders and to inform disaster response planning for Hurricane Matthew. Using R-STaR, responders (n = 126) were e-mailed a daily survey while deployed to document injuries or harmful exposures and a post deployment survey on their post-deployment health and satisfaction with using R STaR. DPH epidemiologists contacted responders reporting injuries or exposures to determine the need for medical care. Frequencies were tabulated for quantitative survey responses, and qualitative data were summarized into key themes. Five percent (6/126) of responders reported injuries, and 81% (43/53) found R-STaR easy to use. Suggestions for R-STaR improvement included improving accessibility using mobile platforms and conducting pre-event training of responders on R-STaR. Lessons learned from R-STaR development and evaluation can inform the development and improvement of responder health surveillance systems at other local and state health departments and disaster and emergency response agencies.

AB - SummaryThis study investigated the breeding parameters and embryogenic development of diploid and heat shock-induced triploid eggs of Anabas testudineus (Bloch, 1792). To this effect, broodstocks of A. testudineus were induced to spawn using the Ovaprim(r) hormone. After fertilization, the eggs were divided into two groups and one portion heat shocked at 41 degrees C (for 3 min), at approximately 4 min after fertilization. Results of fertilization, hatchability, as well as the sequence and timing of embryogenic development were collated from three breeding trials. Fertilization percentages were similar in both treatments (~90%) while hatchability was higher in the diploid eggs (79.56%) than the triploid induced eggs (50.04%). Both treatments had the same sequence of embryogenetic stages; however, the timing of development was significantly delayed in the triploids (i.e. beyond the 2-cell stages) as compared with the observations in the control group (diploid eggs). Consequently, hatching time was 5 h faster in the diploid eggs [i.e. 18 hours post fertilization (hpf)] compared with the triploid induced eggs (23 hpf). The most critical stage of embryonic development in which mass mortality occurred in the different treatments was the somite stage. The status of triploid hatchlings was affirmed using erythrocyte morphology in 2-month-old fingerlings. PMID- 30296963 TI - The learning ability and memory retention of broiler breeders: 1 effects of reduced balanced protein diet on reward based learning. AB - Learning and mental abilities of farm animals are important for their adaptation to new environments and could serve as an indicator for welfare and performance. This study assessed the learning ability and memory retention of broiler breeders through a T-maze test with a reward v. no reward set-up. Feed supplemented with or without meal worms served as a reward. Two trials were conducted with either parent stock (PS) breeders or pure line A (PL) breeders and with the same dietary treatment namely a control (C) group fed with standard commercial diets and a reduced balanced protein (RP) group fed with RP diets (25% reduction of CP and amino acids). To maintain similar target BW, the RP group received on average 10% more feed. A tonic immobility (TI) test was performed to estimate the fearfulness of PS breeders. Most breeders were capable of completing the T-maze tests, but the C group needed less time compared with the RP group when their own feed was given as a reward. However, when meal worms were provided as an extra incentive, the RP group completed the maze significantly faster than the C group. Compared to the C breeders, the RP breeders remained longer in a TI state, indicating a higher level of fearfulness. Long-term memory retention in the T-maze test was observed in both groups. It is concluded that the RP diet had no influences on the learning ability of the reward v. no reward discrimination test and its memory retention of broiler breeders. The increased amount of time the RP breeders needed to solve the test was probably due to a higher sense of fear. Furthermore, the RP diet enhanced the motivation of breeders to obtain an alternative feed such as meal worms. PMID- 30296964 TI - Prevalence thresholds for wasting, overweight and stunting in children under 5 years. AB - OBJECTIVE: Prevalence ranges to classify levels of wasting and stunting have been used since the 1990s for global monitoring of malnutrition. Recent developments prompted a re-examination of existing ranges and development of new ones for childhood overweight. The present paper reports from the WHO-UNICEF Technical Expert Advisory Group on Nutrition Monitoring. DESIGN: Thresholds were developed in relation to sd of the normative WHO Child Growth Standards. The international definition of 'normal' (2 sd below/above the WHO standards median) defines the first threshold, which includes 2.3 % of the area under the normalized distribution. Multipliers of this 'very low' level (rounded to 2.5 %) set the basis to establish subsequent thresholds. Country groupings using the thresholds were produced using the most recent set of national surveys. SETTING: One hundred and thirty-four countries. SUBJECTS: Children under 5 years. RESULTS: For wasting and overweight, thresholds are: 'very low' (~6 times 2.5 %). For stunting, thresholds are: 'very low' (~12 times 2.5 %). CONCLUSIONS: The proposed thresholds minimize changes and keep coherence across anthropometric indicators. They can be used for descriptive purposes to map countries according to severity levels; by donors and global actors to identify priority countries for action; and by governments to trigger action and target programmes aimed at achieving 'low' or 'very low' levels. Harmonized terminology will help avoid confusion and promote appropriate interventions. PMID- 30296965 TI - Forty years on from Alma Ata: present and future of Primary Health Care research. PMID- 30296966 TI - Implications of Brexit on the effectiveness of the UK soft drinks industry levy upon CHD in England: a modelling study. AB - OBJECTIVE: An industry levy on sugar-sweetened beverages (SSB) was implemented in the UK in 2018. One year later, Brexit is likely to change the UK trade regime with potential implications for sugar price. We modelled the effect of potential changes in sugar price due to Brexit on SSB levy impacts upon CHD mortality and inequalities. DESIGN: We modelled a baseline SSB levy scenario; an SSB levy under 'soft' Brexit, where the UK establishes a free trading agreement with the EU; and an SSB levy under 'hard' Brexit, in which World Trade Organization tariffs are applied. We used the previously validated IMPACT Food Policy model and probabilistic sensitivity analysis to estimate the effect of each scenario on CHD deaths prevented or postponed and life-years gained, stratified by age, sex and socio-economic circumstance, in 2021. SETTING: England. SUBJECTS: Adults aged 25 years or older. RESULTS: The SSB levy was associated with approximately 370 (95 % uncertainty interval 220, 560) fewer CHD deaths and 4490 (2690, 6710) life-years gained in 2021. Associated reductions in CHD mortality were 4 and 8 % greater under 'soft' and 'hard' Brexit scenarios, respectively. The SSB levy was associated with approximately 110 (50, 190) fewer CHD deaths in the most deprived quintile compared with 60 (20, 100) in the most affluent, under 'hard' Brexit. CONCLUSIONS: Our study found the SSB levy resilient to potential effects of Brexit upon sugar price. Even under 'hard' Brexit, the SSB levy would yield benefits for CHD mortality and inequalities. Brexit negotiations should deliver a fiscal and regulatory environment which promotes population health. PMID- 30296967 TI - Recent strategies for the diagnosis of early Lyme disease. AB - Lyme disease (LD) is the most common tick-borne disease in the Northern Hemisphere. As the most prevalent vector-borne disease in the USA, LD affects 300,000 human cases each year. LD is caused by inoculation of the bacterial spirochete, Borrelia burgdorferi sensu lato, from an infected tick. If not treated quickly and completely, the bacteria disseminate from the tick's biting site into multiple organs including the joints, heart, and brain. Thus, the best outcome from medical intervention can be expected with early detection and treatment with antibiotics, prior to multi-organ dissemination. In the absence of a characteristic rash, LD is diagnosed using serological testing involving enzyme linked immunosorbent assay (ELISA) followed by western blotting, which is collectively known as the two-tier algorithm. These assays detect host antibodies against the bacteria, but are hampered by low sensitivity, which can miss early LD cases. This review discusses the application of some current assays for diagnosing LD clinically, thus providing a foundation for exploring newer techniques being developed in the laboratory for more sensitive detection of early LD. PMID- 30296968 TI - Evolution of macromolecular structure: a 'double tale' of biological accretion and diversification. AB - The evolution of structure in biology is driven by accretion and diversification. Accretion brings together disparate parts to form bigger wholes. Diversification provides opportunities for growth and innovation. Here, we review patterns and processes that are responsible for a 'double tale' of accretion and diversification at various levels of complexity, from proteins and nucleic acids to high-rise building structures in cities. Parts are at first weakly linked and associate variously. As they diversify, they compete with each other and are selected for performance. The emerging interactions constrain their structure and associations. This causes parts to self-organise into modules with tight linkage. In a second phase, variants of the modules evolve and become new parts for a new generative cycle of higher-level organisation. Evolutionary genomics and network biology support the 'double tale' of structural module creation and validate an evolutionary principle of maximum abundance that drives the gain and loss of modules. PMID- 30296969 TI - Early life nutrition. AB - Nutritionally, the first 1,000 days of an infant's life - from conception to two years - has been identified as a highly influential period, during which lasting health can be achieved. Significant evidence links patterns of infant feeding to both short and long-term health outcomes, many of which can be prevented through nutritional modifications. Recommended globally, breastfeeding is recognised as the gold standard of infant nutrition; providing key nutrients to achieve optimal health, growth and development, and conferring immunologic protective effects against disease. Nevertheless, infant formulas are often the sole source of nutrition for many infants during the first stage of life. Producers of infant formula strive to supply high quality, healthy, safe alternatives to breast milk with a comparable balance of nutrients to human milk imitating its composition and functional performance measures. The concept of 'nutritional programming', and the theory that exposure to specific conditions, can predispose an individual's health status in later life has become an accepted dictum, and has sparked important nutritional research prospects. This review explores the impact of early life nutrition, specifically, how different feeding methods affect health outcomes. PMID- 30296970 TI - Use of contrast-enhanced magnetic resonance imaging of the pelvis to describe changes at different anatomic sites which are potentially specific for polymyalgia rheumatica. AB - OBJECTIVES: To identify inflammatory pelvic structures of patients with polymyalgia rheumatica (PMR) by magnetic resonance imaging (MRI) in detail, searching for a disease-specific pattern. METHODS: A total of 40 contrast enhanced pelvic MRIs of patients with a clinical diagnosis of PMR was reviewed by an experienced musculoskeletal radiologist who assessed all abnormalities semi quantitatively, based on a predefined scoring system. RESULTS: The median (25th/75th percentiles) age of patients was 67 (55/73) years, median symptom duration 13 (6/22) weeks, 55% female, median CRP 1.9 (0.7/4) mg/dl, median ESR 30/1h (17/43). Ten patients were diagnosed with rheumatoid arthritis (25%), in addition to their leading polymyalgic symptom. Multi-locular, mostly bilateral, peritendinous enhancement of pelvic girdle tendons was found to be the hallmark of PMR in all patients. Low-grade hip synovitis was also detected frequently. In all cases, >=4 extracapsular tendinous sites were bilaterally affected. Besides involvement of the common ischiocrural tendon and the glutaeus medius and minimus tendon (present in all cases), an enhancement of the proximal rectus femoris origin was observed in 100% and of the adductor muscles at the inferior medial pubic bone in 90% of cases. The observed MRI pattern patho-anatomically suggests inflammation of the external peritendineum. CONCLUSIONS: The uniformity of the observed pelvic inflammatory pattern detected by contrast-enhanced MRI in PMR patients suggests that it may become relevant for diagnostic purposes. The bilateral involvement of at least 4 extracapsular sites (including the origins of proximal rectus femoris or adductorial muscles) appears to be characteristic of PMR. PMID- 30296971 TI - Imaging of axial spondyloarthritis. New aspects and differential diagnoses. AB - Axial spondyloarthritis (axSpA) is a chronic rheumatic disease characterised by inflammatory back pain and several other disease manifestations and comorbidities. The 2009 ASAS classification criteria differentiate between the classical ankylosing spondylitis or radiographic axSpA and non-radiographic axSpA based on the presence or absence of definite radiographic changes in the sacroiliac joints. Importantly, back pain in patients with axSpA may well have reasons other than axial inflammation or new bone formation. There are several important differential diagnoses such as diffuse idiopathic skeletal hyperostosis and osteitis condensans. This review summarises recent publications concerning the performance of imaging modalities in the field, such as conventional radiography, magnetic resonance imaging, computed tomography and dual energy x ray absorptiometry including the trabecular bone score. PMID- 30296972 TI - Imaging of joints in systemic lupus erythematosus. AB - Musculoskeletal symptoms are among the most common manifestations in patients with systemic lupus erythematosus (SLE), being reported in up to 95% of patients; joint and tendon involvement can range from arthralgia to severe deforming arthropathy; while myositis a rare manifestation, comorbid fibromyalgia is reported in up to 40% of SLE patients. All these manifestations have a significant impact on the patients' quality of life, possibly leading to disability and functional impairment in daily living activities. In recent years, thanks to the availability of new imaging techniques for the assessment of tendon and joint pathologies, the approach to the definition and characterisation of these manifestations in SLE is constantly evolving. In this review we will therefore illustrate the state of the art of imaging techniques in the assessment of joint involvement in SLE, focusing on ultrasounds (US) and magnetic resonance (MRI), discussing their advantages, drawbacks and possible future developments. The main findings that emerge from the recent literature is that imaging studies may allow a more accurate definition of disease subtypes revealing an unexpected higher prevalence of joint and tendon involvement with respect to what known by clinical evaluation and standard radiography. Indeed, US and MRI also made possible the identification of joints and tendons pathologies in patients with no or very mild clinical symptoms. On the other hand, the interpretation of some findings remains uncertain, as well as the validity and feasibility of this analysis in clinical practice. Thus, further studies should clarify the clinical meaning of subclinical abnormalities detected in US and MRI scans and their impact on the long-term outcomes. PMID- 30296973 TI - Imaging detected tenosynovitis of metacarpophalangeal and wrist joints: an increasingly recognised characteristic of rheumatoid arthritis. AB - Tenosynovitis is traditionally recognised at physical examination in patients with inflammatory rheumatic diseases, such as, e.g. psoriatic arthritis and (longstanding) rheumatoid arthritis (RA). The increasing use of sensitive imaging techniques (ultrasound, magnetic resonance imaging (MRI)) has recently revealed that subclinical tenosynovitis is prevalent in early RA and in patients in different phases of RA development (asymptomatic state, arthralgia, early arthritis). In this review, the recent findings on MRI-detected tenosynovitis and associations with RA development are highlighted, and an overview of the most reported inflamed tendon locations within the hand and wrist of patients in different disease phases is provided. The data presented show that tenosynovitis is one of the earliest inflammatory features in patients with imminent RA and associated with impairment of activities in daily life. The value of tenosynovitis as an outcome measure in RA is also discussed. PMID- 30296974 TI - Update on magnetic resonance imaging and ultrasound in rheumatoid arthritis. AB - Rheumatoid arthritis (RA) disease activity often remains difficult to assess and quantify accurately. As a result, numerous measures using various techniques to estimate clinical activity have been developed for clinical research and care. More objective imaging biomarkers for early detection and accurate, quantitative measurement of the disease burden are therefore of interest both for clinical use and for investigational studies. Two widely studied imaging biomarkers are magnetic resonance imaging (MRI) and ultrasound (US), imaging tests that are increasingly available to clinicians. While substantial and increasing evidence has been reported that these tools are valid and provide advantages in both clinical trials and clinical assessments, more information is needed to inform their appropriate use in routine clinical care. The goals of this review are to outline the current literature regarding each of these objective imaging tools, assess their strengths and limitations, and to clarify knowledge gaps to be filled before these techniques may be more optimally utilised. PMID- 30296975 TI - The use of ultrasound in the management of large-vessel vasculitis: an evolving concept. AB - Imaging is increasingly recognised as an essential element in the management of several rheumatologic conditions. Ultrasound is in widespread use as a safe, reproducible, and directly interpretable method for diagnosis and evaluation of arthritis and increasingly of large-vessel vasculitis (LVV). Indeed, the diagnosis and management of LVV are being transformed through the use of imaging. Increasing and more standardised evidence is being produced on the role of colour duplex sonography in the management of LVV. Nonetheless, some controversies and unresolved issues remain. This review describes current findings and reviews future perspectives in the use of ultrasound for the diagnosis and management of LVV. PMID- 30296976 TI - MRI in imaging of rheumatic diseases: an overview for clinicians. AB - Magnetic resonance imaging (MRI) is a technique that utililises powerful magnets and radiofrequency to produce 3-dimentional images. MRI does not involve ionising radiation and has superb tissue resolution, enabling excellent delineation of anatomy as well as pathology in joints. This article briefly reviews the technical principle of magnetic resonance and discusses advantages and disadvantages of the technique, with particular attention to rheumatologic imaging. New information is summarised concerning the use of contrast media, dynamic, contrast-enhanced MRI, diffusion-weighted imaging, cartilage imaging and whole-body MRI. PMID- 30296977 TI - Enthesitis detection by ultrasound: where are we now? AB - Over the last 25 years, ultrasound has been used to evaluate involvement at the entheses in spondyloarthritis (SpA) and psoriatic arthritis (PsA). Several studies have been reported indicating its value in detecting active inflammation at entheseal sites using both gray scale and Doppler findings. This review explores the recent literature and appraises the current knowledge and the unmet needs of enthesitis detection by ultrasound in the management of both SpA and PsA. PMID- 30296978 TI - The peripheral nerves: update on ultrasound and magnetic resonance imaging. AB - The motor and sensory branches of the somatic peripheral nervous system (PNS) can be visualised by different imaging systems. This article focuses on imaging of peripheral nerves by magnetic resonance imaging (MRI) and high-resolution ultrasound (US). The anatomic basis of the peripheral nerve image, common pathologies and clinical value of US and MRI imaging of peripheral nerves are reviewed. PMID- 30296979 TI - Update on imaging in gout: contrasting and comparing the role of dual-energy computed tomography to traditional diagnostic and monitoring techniques. AB - In this systematic literature review, we update imaging modalities in gout, with a focus on newer technologies, particularly Dual-energy computed tomography (DECT). Conventional radiography (CR), ultrasonography (US), magnetic resonance imaging (MRI), computed tomography (CT) and dual-energy CT (DECT) have been used to evaluate different stages and clinical manifestations of gout and hyperuricaemia. We compare and contrast these modalities across the spectrum of this disease and of clinical scenarios and objectives (1). PMID- 30296980 TI - Update on imaging in rheumatic diseases. PMID- 30296981 TI - Update on imaging in rheumatic diseases: cartilage. AB - In recent years, the role of articular cartilage for understanding pathogenesis as well as for clinical research has become increasingly important. Whereas previously cartilage could only be assessed invasively, various imaging procedures are available for its evaluation now. Although still widely used, conventional radiography bears significant limitations since it assesses cartilage indirectly by joint space width. Today, the cartilage thickness and structure can be reliably evaluated using ultrasound, although the molecular structure cannot be determined, yet. Besides ultrasound, MRI offers the possibility to image morphological changes with a very high resolution. In addition, the quality and composition of joint cartilage can already be measured due to a constant technical improvement and new MRI sequences such as dGEMRIC even in small joints (e.g. MCP or MTP joints). Despite the advantages of contrast agents for the detection of inflammation, its use is reevaluated today. Regarding that contrast agent-free imaging techniques for the assessment of joint cartilage are developed with great effort to depict its quality and changes over time. These novel MRI methods such as T2/T2*- and T1rho-mapping, gagCEST, and sodium imaging provide promising quantitative imaging biomarkers that can detect early cartilage changes before morphological alterations occur. Hence, US and MRI will likely be of paramount importance in future clinical trials and clinical assessment of inflammatory and degenerative joint diseases not only for understanding pathogenesis but also for using its possible value in daily practice. PMID- 30296982 TI - The role of imaging in evaluating patients with idiopathic inflammatory myopathies. AB - OBJECTIVES: To describe imaging modalities for diagnosing and monitoring of patients with idiopathic inflammatory myopathies. METHODS: A detailed literature search summarising recent data documenting the contribution of different imaging techniques to current management of idiopathic inflammatory myopathies was performed. RESULTS: An overview of methods most frequently used for evaluation of inflammatory myopathies and the description of their role in the diagnostic and monitoring process is presented. CONCLUSIONS: MRI is currently the most useful method capable of demonstrating both inflammatory and post-inflammatory changes in the muscles and surrounding soft tissue. Several studies have documented potential usefulness of other imaging techniques, such as ultrasonography, positron emission tomography, scintigraphy, and dual-energy x-ray absorptiometry. PMID- 30296983 TI - Ultrasonography in gout: utility in diagnosis and monitoring. AB - The use of ultrasonography has a considerable potential for diagnosis and monitoring of gout due to its capacity to detect urate crystal deposits in joints, e.g. on the cartilage surface, visualised as the double contour sign, and in soft tissues, e.g. as tophi. Furthermore, ultrasonography can visualise both synovitis and bone erosion. Consensus-based definitions for ultrasonographic elementary lesions in gout were validated in 2015, and ultrasonography is already included in the 2015 ACR/EULAR classification criteria for gout. This report evaluates the current literature on the use of ultrasonography for diagnosing and monitoring gout. PMID- 30296984 TI - Recent advances in research imaging of osteoarthritis with focus on MRI, ultrasound and hybrid imaging. AB - For imaging of osteoarthritis (OA), MRI plays a major role in the research setting, with compositional MRI techniques becoming increasingly more important thanks to their capacity to assess 'premorphologic' biochemical compositional changes of articular and periarticular tissues. Although radiography remains the primary imaging modality in OA clinical trials, known limitations for visualisation of OA features significantly limits the utility of radiography both clinically and in the research arena. Compositional MRI techniques can potentially supplement routine clinical MRI sequences to identify cartilage degeneration at an earlier stage when radiographs may be normal. Ultrasound can be a useful adjunct to radiography and MRI particularly for evaluation of hand OA and for the evaluation of synovitis. Emerging hybrid imaging techniques including PET/MRI and PET/CT allow evaluation of the joint with simultaneous assessment of morphological changes and metabolic activities, showing a potential for these hybrid systems to play an increasing role in OA research. PMID- 30296985 TI - Magnetic resonance imaging and magnetic resonance angiography in large-vessel vasculitides. AB - The role of imaging in diagnosis and monitoring of vasculitides has steadily become more important during the last years. As a result of the technological progress, its low invasiveness and its relatively good diagnostic reliability, magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) are increasingly used in the assessment of vasculitic changes of extra- and intra cranial arteries. The aim of this review is to outline the significance of different imaging modalities, particularly the significance of MRI/MRA, in the context of large-vessel vasculitides, especially in regard to the first EULAR (The European League Against Rheumatism)-recommendations on the role of imaging in the process of diagnosis and monitoring of patients with suspected large vessel vasculitides. Furthermore, some typical imaging findings as well as the basics of MRI technique are to be presented. PMID- 30296986 TI - The role of cardiovascular magnetic resonance imaging in rheumatic heart disease. AB - Cardiovascular involvement is a well-known feature of inflammatory rheumatic diseases, although often clinically silent, so early cardiovascular involvement may remain unrecognised. Thus, increased awareness and improved insights into the pathomechanisms of heart disease in the context of inflammatory rheumatic disease has led to an emerging role of cardiovascular magnetic resonance (CMR) as an accurate and non-invasive diagnostic test for detection of early (as well as late) cardiovascular involvement in inflammatory rheumatic disease. The present article will review the current potential as well as the limitations of established and emerging, qualitative and quantitative CMR techniques in the setting of inflammatory rheumatic disease and shed some light onto current developments in the field. PMID- 30296987 TI - Overview of musculoskeletal ultrasound for the clinical rheumatologist. AB - Within the realm of rheumatology, the field of musculoskeletal ultrasound (MSUS) has grown exponentially over the last few decades. This review, aimed at the clinical rheumatologist, provides a basic overview of the principles of image generation and the commonly used clinical applications of MSUS, while also highlighting its advantages and limitations. In particular, the role of MSUS in the assessment of early and established rheumatoid arthritis, crystalline disease, the spondyloarthropathies and Sjogren's disease is discussed in more detail and by reviewing the pertinent literature. PMID- 30296988 TI - Imaging in peripheral and axial psoriatic arthritis: contributions to diagnosis, follow-up, prognosis and knowledge of pathogenesis. AB - Imaging in psoriatic arthritis (PsA) is rapidly evolving, and the use of sensitive modalities both in clinical research and routine care is increasing. This article provides an overview of current knowledge of different imaging methods in PsA, including current and possible future use in diagnosis, prognosis and clinical management, value in understanding pathogenesis, and latest activities to establish responsive imaging outcome measures. Much research remains to be performed concerning imaging in PsA, particularly on its optimal use in routine clinical care, the clinical consequences of imaging-detected subclinical disease, and specific and sensitive PsA imaging outcome measures. PMID- 30296989 TI - The role of 18F-FDG positron emission tomography for the diagnosis of vasculitides. AB - Large-vessel vasculitis is the most common form of primary vasculitis comprising cranial and large-vessel giant cell arteritis, Takayasu's arteritis and idiopathic aortitis. Prompt diagnosis and treatment of large-vessel vasculitis are important to prevent potentially serious emergencies such as visual loss, vascular stenosis and aneurysm formation. Temporal artery biopsy has long been the standard for diagnosing GCA - an invasive technique that lacks sensitivity compared to a clinical diagnosis that relies on a combination of clinical symptoms, elevated serum inflammatory markers and imaging findings. Conventional angiography focussing on the detection of arterial stenoses and occlusion does not assess vessel wall changes. Therefore, angiography is being increasingly replaced by newer imaging modalities such as magnetic resonance imaging and 18F FDG positron emission tomography-computed tomography. However, imaging modalities also including ultrasound are not uniformly used for diagnosis and monitoring of large-vessel vasculitis in clinical practice. Very recently recommendations for imaging have been developed by the European League Against Rheumatism and the Society of Nuclear Medicine and Molecular Imaging in cooperation with the European Association of Nuclear Medicine and an interest group endorsed by the American Society of Nuclear Cardiology. These and a small literature search using PubMed are the basis for this review. PMID- 30296990 TI - The use of ultrasound for assessing interstitial lung involvement in connective tissue diseases. AB - Interstitial lung disease (ILD) is one of the most serious pulmonary complications associated with connective tissue diseases (CTDs), resulting in significant morbidity and mortality. Recently, lung ultrasound examination has appeared as a useful, feasible, non-invasive, radiation-free imaging technique with high sensitivity and specificity for the diagnosis of CTD-associated ILD. In this review, we discuss the literature concerning lung ultrasound findings (B lines and pleural irregularities) in systemic sclerosis. We also examine the possible utility and potential limitations of lung ultrasound in other CTDs including: inflammatory myopathies, mixed connective tissue disease, and Sjogren's syndrome. Specifically, we compare the diagnostic accuracy of lung ultrasound with traditional imaging techniques and pulmonary functional tests. PMID- 30296991 TI - Advances in salivary gland ultrasonography in primary Sjogren's syndrome. AB - Salivary gland ultrasonography (US) has recently been re-discovered as a useful tool to assess salivary gland involvement in primary Sjogren's syndrome (SS). In this review, we discuss US of the major salivary glands in the diagnosis of primary SS and analyse the possible added value of inclusion in classification criteria. We review the literature concerning associations between US of the major salivary glands, salivary gland histology and serology, with the possibility that US may be of value in disease stratification. We also examine the possible utility for US to monitor patient response to therapy in both clinical research and standard clinical care. PMID- 30296992 TI - Functional MRI in rheumatic diseases with a focus on fibromyalgia. AB - Pain is the most common symptom in rheumatic diseases. However, the severity of pain does not correlate with pathology. The lack of an objective test for pain results in clinicians consider pain in patients with fibromyalgia as psychological. Research over the last two decade using functional neuroimaging especially functional MRI scan have demonstrated objectively that patients with fibromyalgia were not malingering. Pain processing is complex and multiple regions of the brain are involved. One consistent finding is decrease activity in regions of the brain involved in pain inhibitory pathways suggesting this is one of the fundamental pathophysiology processes in fibromyalgia. PMID- 30296993 TI - Current imaging techniques in osteoporosis. AB - Osteoporosis is a global pandemic affecting children, men and women of all ages and ethnicities. Millions of people suffer fragility fractures each year around the world as a result of this bone disease, which can have devastating consequences for them, including permanent disability and death. Many fractures are preventable by identifying people at high risk for fracture and falls, and diagnosing those who already have osteoporosis, before they fracture. Rheumatologists commonly encounter people with fragile bones, either as an isolated entity, or a co-morbidity to their underlying rheumatic illness or treatment. Imaging in osteoporosis can be used to make a diagnosis, while measurements of bone and body tissues, most commonly bone mineral density, can be used to identify those at risk and monitor them following treatment. Modern densitometry scanners may have multiple new features including measures of hip geometry, trabecular bone score, finite element analysis, fat and muscle mass, and may have additional imaging features including vertebral fracture assessment and atypical femoral fracture screening. When used correctly, these tools provide invaluable information for the assessment of the effectiveness of interventions in clinical studies, and patient management in clinical practice. In this article we review osteoporosis imaging techniques, with an emphasis on dual-energy x-ray absorptiometry, and how to apply and interpret them in modern rheumatology practice. PMID- 30296995 TI - The randomness that shapes our DNA. AB - Just 5% of the human genome is subject to neutral evolution, but this process remains central to understanding the history of human migration across the Earth. PMID- 30296994 TI - Personality links with lifespan in chimpanzees. AB - Life history strategies for optimizing individual fitness fall on a spectrum between maximizing reproductive efforts and maintaining physical health over time. Strategies across this spectrum are viable and different suites of personality traits evolved to support these strategies. Using data from 538 captive chimpanzees (Pan troglodytes) we tested whether any of the dimensions of chimpanzee personality - agreeableness, conscientiousness, dominance, extraversion, neuroticism, and openness - were associated with longevity, an attribute of slow life history strategies that is especially important in primates given their relatively long lives. We found that higher agreeableness was related to longevity in males, with weaker evidence suggesting that higher openness is related to longer life in females. Our results link the literature on human and nonhuman primate survival and suggest that, for males, evolution has favored the protective effects of low aggression and high quality social bonds. PMID- 30296997 TI - Infective Endocarditis. AB - Infective endocarditis (IE) is an uncommon infection of cardiac valves associated with bacteremia. It increasingly affects elderly patients with chronic disease and artificial cardiac devices. The presentation, however, remains subtle and varied, with nonspecific symptoms ranging from those resembling a mild viral infection to septic shock and multiorgan failure. IE carries potential to cause significant morbidity and mortality through its impact on cardiac function and from embolic complications. Blood cultures prior to antibiotics and obtaining prompt echocardiography are key diagnostic steps, followed by proper selection of empiric antibiotics and, in many cases, collaboration with infectious disease, cardiology, and cardiothoracic surgery specialists. PMID- 30296996 TI - Oldest skeleton of a fossil flying squirrel casts new light on the phylogeny of the group. AB - Flying squirrels are the only group of gliding mammals with a remarkable diversity and wide geographical range. However, their evolutionary story is not well known. Thus far, identification of extinct flying squirrels has been exclusively based on dental features, which, contrary to certain postcranial characters, are not unique to them. Therefore, fossils attributed to this clade may indeed belong to other squirrel groups. Here we report the oldest fossil skeleton of a flying squirrel (11.6 Ma) that displays the gliding-related diagnostic features shared by extant forms and allows for a recalibration of the divergence time between tree and flying squirrels. Our phylogenetic analyses combining morphological and molecular data generally support older dates than previous molecular estimates (~23 Ma), being congruent with the inclusion of some of the earliest fossils (~36 Ma) into this clade. They also show that flying squirrels experienced little morphological change for almost 12 million years. PMID- 30296998 TI - Community-Acquired Pneumonia. AB - Community-acquired pneumonia is one of the most common infections seen in emergency department patients. There is a wide spectrum of disease severity and viral pathogens are common. After a careful history and physical examination, chest radiographs may be the only diagnostic test required. The first step in management is risk stratification, using a validated clinical decision rule and serum lactate, followed by early antibiotics and fluid resuscitation when indicated. Antibiotics should be selected with attention to risk factors for multidrug-resistant respiratory pathogens. Broad use of pneumococcal vaccine in adults and children can prevent severe community-acquired pneumonia. PMID- 30296999 TI - The Emergency Department Diagnosis and Management of Urinary Tract Infection. AB - Urinary tract infection (UTI) is a common infection seen in the emergency department. The spectrum of UTI includes simple versus complicated infection and lower versus upper UTI. No one history or examination finding is definitive for diagnosis. Testing often includes urinalysis and/or urine dipstick, and several pitfalls may occur in interpretation. Urine cultures should be obtained in complicated or upper UTIs but not simple and lower tract UTIs, unless a patient is pregnant. Imaging often is not required. Most patients with simple cystitis and pyelonephritis are treated as outpatients. A variety of potentially dangerous conditions may mimic UTI and pyelonephritis. PMID- 30297000 TI - Emergency Department Approach to the Patient with Suspected Central Nervous System Infection. AB - Central nervous system (CNS) infections require early recognition and aggressive management to improve patient survival and prevent long-term neurologic sequelae. Although early detection and treatment are important in many infectious syndromes, CNS infections pose unique diagnostic and therapeutic challenges. The nonspecific signs and symptoms at presentation, lack of characteristic infectious changes in laboratory and imaging diagnostics, and closed anatomic and immunologically sequestered space each present challenges to the emergency physician. This article proposes an approach to the clinical evaluation of patients with suspected CNS infection and highlights methods of diagnosis, treatment, and complications associated with CNS infections. PMID- 30297001 TI - Skin and Soft Tissue Infections in the Emergency Department. AB - This article covers the diagnosis and treatment of skin and soft tissue infections commonly encountered in the emergency department: impetigo, cutaneous abscesses, purulent cellulitis, nonpurulent cellulitis, and necrotizing skin and soft tissue infections. Most purulent infections in the United States are caused by methicillin-resistant Staphylococcus aureus. For abscesses, we emphasize the importance of incision and drainage. Nonpurulent infections are usually caused by streptococcal species and initial empiric antibiotics need not cover methicillin resistant Staphylococcus aureus. For uncommon but potentially lethal necrotizing skin and soft tissue infections, the challenge is rapid diagnosis in the emergency department and prompt surgical exploration and debridement. PMID- 30297003 TI - Management of Patients with Sexually Transmitted Infections in the Emergency Department. AB - Sexually transmitted infections (STI) are very common infections in the United States. Most patients with STIs are evaluated and treated in primary care settings; however, many also present to the Emergency Department (ED) for initial care. Management of STIs in the ED includes appropriate testing and treatment per CDC Sexually Transmitted Diseases Treatment Guidelines. Although most patients with STIs are asymptomatic or may only exhibit mild symptoms, serious complications from untreated infection are possible. Pregnant women with STIs are particularly vulnerable to serious complications; therefore, empiric ED treatment combined with close follow-up care and referral to obstetrics are paramount. PMID- 30297004 TI - Management of Human Immunodeficiency Virus in the Emergency Department. AB - Over the past 30 years, significant advances have transformed the landscape of human immunodeficiency virus (HIV) care in the emergency department. Diagnosis and management of HIV has improved, resulting in a decline in the incidence of acquired immunodeficiency syndrome (AIDS)-defining infections. Advances in pharmacology have led to fewer serious medication toxicities and more tolerable regimens. Emergency providers have played an increasingly important role in HIV screening and diagnosis of acute infection. Provision of postexposure prophylaxis is expanding from a focus on occupational exposure to include all high-risk cases. PMID- 30297002 TI - Musculoskeletal Infections in the Emergency Department. AB - Bone and joint infections are potentially limb-threatening or even life threatening diseases. Emergency physicians must consider infection when evaluating musculoskeletal complaints, as misdiagnosis can have significant consequences. Patients with bone and joint infections can have heterogeneous presentations with nonspecific signs and symptoms. Staphylococcus aureus is the most commonly implicated microorganism. Although diagnosis may be suggested by physical examination, laboratory testing, and imaging, tissue sampling for Gram stain and microbiologic culture is preferable, as pathogen identification and susceptibility testing help optimize long-term antibiotic therapy. A combination of medical and surgical interventions is often necessary to effectively manage these challenging infections. PMID- 30297005 TI - Infectious Disease Emergencies in Oncology Patients. AB - Oncology patients are a unique patient population in the emergency department (ED). Malignancy and associated surgical, chemotherapeutic, or radiation therapies put them at an increased risk for infection. The most ominous development is neutropenic fever, which happens often and may not present with signs or symptoms other than fever. A broad differential diagnosis is essential when considering infectious disease pathology in both neutropenic and non neutropenic oncology patients in the ED. PMID- 30297007 TI - Biothreat Agents and Emerging Infectious Disease in the Emergency Department. AB - The challenges faced by the emergency physician with recognizing and treating category A biothreat agents and emerging infectious disease are summarized and reviewed. PMID- 30297006 TI - Approach to Transplant Infectious Diseases in the Emergency Department. AB - The emergency department (ED) is an increasingly important site of care for patients who have undergone solid organ transplantation or hematopoietic cell transplantation. It is paramount for emergency physicians to recognize infections early on, obtain appropriate diagnostic testing, initiate empirical antimicrobial therapy, and consider specialty consultation and inpatient admission when caring for these patients. This review provides emergency physicians with an approach to the assessment of transplant patients' underlying risk for infection, formulation of a broad differential diagnosis, and initial management of transplant infectious disease emergencies in the ED. PMID- 30297009 TI - Antimicrobial Stewardship in the Emergency Department. AB - The emergency department (ED) is the hub of the US health care system. Acute infectious diseases are frequently encountered in the ED setting, making this a critical setting for antimicrobial stewardship efforts. Systems level and behavioral stewardship interventions have demonstrated success in the ED setting but successful implementation depends on institutional support and the presence of a physician champion. Antimicrobial stewardship efforts in the ED should target high-impact areas: antibiotic prescribing for nonindicated respiratory tract conditions, such as bronchitis and sinusitis; overtreatment of asymptomatic bacteriuria; and using two antibiotics (double coverage) for uncomplicated cases of cellulitis or abscess.

AB - Hydrologic disasters, including hurricanes, tsunamis, and severe flooding, have been associated with infectious diseases, particularly among vulnerable and displaced populations in resource-poor settings. Skin and soft tissue infections, gastrointestinal infections, respiratory infections, zoonotic infections, and vector-borne diseases each present unique threats to human health in this setting. Increased emergency physician awareness of these infectious diseases and their diagnosis and management helps optimize medical care for survivors after a hydrologic disaster and safeguard the health of disaster responders.

PMID- 30297013 TI - Is Internalization an End in Itself or a Means to an End? PMID- 30297010 TI - Infection Prevention for the Emergency Department: Out of Reach or Standard of Care? AB - The emergency department (ED) presents unique challenges to infection control and prevention. Hand hygiene, transmission-based precautions, environmental cleaning, high-level disinfection and sterilization of reusable medical devices, and prevention of health care-associated infections (catheter-associated urinary tract infection, ventilator-associated pneumonia, central line-associated bloodstream infection) are key priorities in ED infection prevention. Effective and sustainable infection prevention strategies tailored to the ED are necessary and achievable. Emergency clinicians can and already play an invaluable role in infection prevention. PMID- 30297016 TI - Digital Promotion of Energy Drinks to Young Adults Is More Strongly Linked to Consumption Than Other Media. AB - OBJECTIVE: To examine whether digital marketing strategies are more strongly associated with energy drink use than other marketing and whether Theory of Planned Behavior (TPB) constructs mediated the effects of digital marketing on energy drink use. DESIGN: A cross-sectional online survey using the TPB was administered in 2016. SETTING: Illawarra region of New South Wales, Australia. PARTICIPANTS: A total of 359 young adults aged 18-24 years completed the survey. Participants were mainly students. MAIN OUTCOME MEASURES: Relative impacts of digital and other marketing on energy drink use and the mediating effects of TPB constructs: attitudes, subjective norm, and perceived behavioral control. ANALYSIS: Stepwise regression analysis was employed to compare the effects on energy drink use from digital and other marketing. Mediation analysis was used to examine the mediating effects of the TPB constructs. RESULTS: Digital marketing was more strongly associated than other marketing with young adults' energy drink use. Attitudes, subjective norms, and perceived behavioral control mediated the effects of digital marketing on energy drink use. CONCLUSIONS AND IMPLICATIONS: The marketing of unhealthy food and beverages such as energy drink products on the Internet requires greater scrutiny. Future interventions may focus on strategies to attenuate young adults' attitudes toward energy drinks, denormalize energy drink use, and strengthening self-efficacy to reject energy drinks among this age group. PMID- 30297015 TI - Nutrition Label Use and Its Association With Dietary Quality Among Latinos: The Roles of Poverty and Acculturation. AB - OBJECTIVE: To investigate how acculturation and poverty are independently and jointly associated with the use of the Nutrition Facts panel (nutrition label) and to examine the extent to which nutrition label use moderates the association of poverty and acculturation on dietary quality among Latinos. DESIGN: Cross sectional analysis of the 2007/2008 and 2009/2010 waves of the National Health and Nutrition Examination Survey. PARTICIPANTS: A total of 3,696 adults (aged >19 years) self-identified as Latino/Hispanic with food label use data from the most recent Consumer Behavior Phone Follow-Up Modules. MAIN OUTCOME MEASURE(S): Nutrition label use and dietary quality. ANALYSIS: Logistic regression. RESULTS: Acculturation moderated the association of income on the likelihood of using nutrition labels, such that lower-income English-speaking Latinos were half as likely as higher-income English-speakers to use nutrition labels (P = .01, odds ratio [OR] = 0.44, 95% confidence interval [CI], 0.24-0.81); however, Spanish speakers were equally likely to use nutrition labels across income levels (P = .99; OR = 1.00; 95% CI, 0.77-1.31). Nutrition label use moderated the association of acculturation on diet. Among English-speaking Latinos, those who read nutrition labels had less than half the risk for poor diet (P =.001; OR = 0.43; 95% CI, 0.26-0.69); however, label use was not significantly associated with the diet quality of Spanish speakers (P = .07; OR = 0.82; 95% CI, 0.67-1.02). Nutrition label use decreased the risk for poor dietary quality regardless of poverty status. CONCLUSIONS AND IMPLICATIONS: Overall, results demonstrated a positive association between the use of the Nutrition Facts panel for Latinos and dietary quality. An important nutrition education strategy among bicultural Latinos at risk for a poor diet as a result of acculturation may include label reading comprehension. This approach may also address the low rates of label use. The study provides evidence of segmented assimilation in which low-income, bicultural Latinos follow an underclass pattern of acculturation demonstrated by a lower likelihood of reading nutrition labels and higher-income, bicultural Latinos follow the more successful selective pattern. PMID- 30297017 TI - Examining the Accuracy and Use of Portion Size Estimation Aids in Parents of Children With Obesity: A Randomized Controlled Trial. AB - OBJECTIVE: To determine parents' (1) accuracy in using portion size estimation aids (PSEAs) to estimate portion sizes and (2) use of PSEAs at home. METHODS: Parents (n = 37) of children in a pediatric weight management clinic were recruited, enrolled in a parallel-design, randomized, controlled trial, and assigned to receive a 2-dimensional (2D) or 3D PSEA. Percent absolute estimation accuracy was examined across groups and food types. Survey responses were organized according to frequencies and percentages were calculated. RESULTS: Main effects of group, food type, and group * food type interaction were significant (all P < .05). The 2D PSEAs yielded more accurate estimates of portion sizes for amorphous foods. Overall, parents' estimation accuracy was poor. Participants were satisfied and found the PSEAs to be useful. CONCLUSIONS AND IMPLICATIONS: The 2D PSEAs led to greater accuracy in estimating portions of amorphous foods. Parents showed poor accuracy in estimating portion sizes. This study highlights the role of dietitians and nutrition educators in enhancing portion estimation accuracy. PMID- 30297019 TI - Corrigendum. PMID- 30297018 TI - Dietary Intake Changes in Response to a Sugar-Sweetened Beverage Reduction Trial for Various Supplemental Nutrition Assistance Program (SNAP) Eligibility Groups. AB - OBJECTIVE: To examine dietary intake differences resulting from a sugar-sweetened beverage reduction intervention by 3 Supplemental Nutrition Assistance Program (SNAP) participation groups: SNAP participants (n = 56), income-eligible nonparticipants (n = 30), and income-ineligible nonparticipants (n = 60). METHODS: Adults in southwest Virginia were enrolled in a 6-month behavioral trial. The researchers collected SNAP enrollment status and 3 24-hour dietary recalls at baseline and 6 months. Repeated-measures ANOVAs were used to assess differences in dietary intake among SNAP participation groups. RESULTS: No significant group * time differences were found for energy density, Healthy Eating Index scores, Healthy Beverage Index scores, or intake of total calories, added sugars, and sugar-sweetened beverages. However, several within-group improvements were noted: income-ineligible nonparticipants and SNAP participants improved in more areas compared with income-eligible nonparticipants, including intake of total calories, added sugars, and sugar-sweetened beverages. CONCLUSIONS AND IMPLICATIONS: This exploratory analysis suggests that the overall effectiveness of a sugar-sweetened beverage intake reduction intervention was not influenced by SNAP eligibility and participation status, because there were no significant group by time differences over the intervention. It is important to recognize for future programs that different approaches to improving dietary intake may be needed to match the characteristics of this audience better. This may be accomplished by attempting to decrease the disparity gap between income eligible nonparticipants and those receiving SNAP or who are income ineligible through the use of programs such as SIPsmartER.

PPC6803: Influence on the estimation of Photosystem II maximal quantum efficiency. AB - The fluorescence emission spectrum of Synechocystis sp. PPC6803 cells, at room temperature, displays: i) significant bandshape variations when collected under open (F0) and closed (FM) Photosystem II reaction centre conditions; ii) a marked dependence on the excitation wavelength both under F0 and FM conditions, due to the enhancement of phycobilisomes (PBS) emission upon their direct excitation. As a consequence: iii) the ratio of the variable and maximal fluorescence (FV/FM), that is a commonly employed indicator of the maximal photochemical quantum efficiency of PSII (Phipc, PSII), displays a significant dependency on both the excitation and the emission (detection) wavelength; iv) the FV/FM excitation/emission wavelength dependency is due, primarily, to the overlap of PSII emission with that of supercomplexes showing negligible changes in quantum yield upon trap closure, i.e. PSI and a PBS fraction which is incapable to transfer the excitation energy efficiently to core complexes. v) The contribution to the cellular emission and the relative absorption-cross section of PSII, PSI and uncoupled PBS are extracted using a spectral decomposition strategy. It is concluded that vi) Phipc, PSII is generally underestimated from the FV/FM measurements in this organism and, the degree of the estimation bias, which can exceed 50%, depends on the measurement conditions. Spectral modelling based on the decomposed emission/cross-section profiles were extended to other processes typically monitored from steady-state fluorescence measurements, in the presence of an actinic illumination, in particular non-photochemical quenching. It is suggested that vii) the quenching extent is generally underestimated in analogy to FV/FM but that viii) the location of quenching sites can be discriminated based on the combined excitation/emission spectral analysis. PMID- 30297026 TI - Molecular identification and functional characterization of a novel glutamate transporter in yeast and plant mitochondria. AB - The genome of Saccharomyces cerevisiae encodes 35 members of the mitochondrial carrier family (MCF) and 58 MCF members are coded by the genome of Arabidopsis thaliana, most of which have been functionally characterized. Here two members of this family, Ymc2p from S. cerevisiae and BOU from Arabidopsis, have been thoroughly characterized. These proteins were overproduced in bacteria and reconstituted into liposomes. Their transport properties and kinetic parameters demonstrate that Ymc2p and BOU transport glutamate, and to a much lesser extent L homocysteinesulfinate, but not other amino acids and many other tested metabolites. Transport catalyzed by both carriers was saturable, inhibited by mercuric chloride and dependent on the proton gradient across the proteoliposomal membrane. The growth phenotype of S. cerevisiae cells lacking the genes ymc2 and agc1, which encodes the only other S. cerevisiae carrier capable to transport glutamate besides aspartate, was fully complemented by expressing Ymc2p, Agc1p or BOU. Mitochondrial extracts derived from ymc2Deltaagc1Delta cells, reconstituted into liposomes, exhibited no glutamate transport at variance with wild-type, ymc2Delta and agc1Delta cells, showing that S. cerevisiae cells grown in the presence of acetate do not contain additional mitochondrial transporters for glutamate besides Ymc2p and Agc1p. Furthermore, mitochondria isolated from wild type, ymc2Delta and agc1Delta strains, but not from the double mutant ymc2Deltaagc1Delta strain, swell in isosmotic ammonium glutamate showing that glutamate is transported by Ymc2p and Agc1p together with a H+. It is proposed that the function of Ymc2p and BOU is to transport glutamate across the mitochondrial inner membrane and thereby play a role in intermediary metabolism, C1 metabolism and mitochondrial protein synthesis. PMID- 30297027 TI - Light transmission/absorption characteristics of the meibomian gland. AB - PURPOSE: While meibography has proven useful in identifying structural changes in the meibomian gland (MG), little is known regarding the MG spectral transmission and absorption characteristics. The purpose of this study was to measure the transmission/absorption spectra of the MG compared to other eyelid tissues. METHODS: Human and rabbit eyelids were fixed in paraformaldehyde, serial sectioned (50 MUm) using a cryotome and imaged by brightfield and reflectance microscopy. Eyelid regions (MG, muscle, tarsus and dermis) were then illuminated by a 100 MUm spot using a infrared enhanced white light source. Transmission spectra over a 550-950 nm range were then measured using a spectrometer and differences compared using two-way analysis of variance. RESULTS: Brightfield microscopy of both human and rabbit eyelid tissue showed a marked decrease in light transmission for MG acini compared to other eyelid tissues. In rabbit, the dermis showed 5* and the muscle showed 2* more light transmission compared to MG (P < .001 and P < .001, respectively). For human, the muscle showed 14* and the tarsus showed 84* more light transmission compared to MG (P < .01 and P < .001, respectively). No specific spectral region of light absorption could be detected in either rabbit or human MG. Loss of light transmission in MG was localized to acini containing small lipid droplets, averaging 2.7 +/- 0.8 MUm in diameter. CONCLUSIONS: The data suggest that light transmission is dramatically reduced in the acini due to light scattering by small lipid droplets, suggesting that Meibography detects active lipid synthesis in differentiating meibocytes. PMID- 30297028 TI - Subjective versus objective dry eye disease in patients with moderate-severe thyroid eye disease. AB - PURPOSE: To compare the subjective versus Objective dry eye disease (DED) in patients with moderate-severe thyroid eye disease (TED). METHOD: Included were the patients with moderate-severe TED and >=18 years old. They completed the ocular surface disease index (OSDI) questionnaire and had Schirmer, Tear breakup time (TBUT), fluorescein staining, osmolarity, corneal aesthesiometry, and meibomian gland dysfunction (MGD) tests. Excluded were patients with history of any disease, surgery and or medications which might be affecting the ocular surface and incomplete tests results. Subjective DED was defined as OSDI score of >=13 and objective as one abnormal sign (TBUT, Schirmer, Osmolarity, and Staining). Presence of both was defined as definite DED. RESULTS: Included were 38 patients (74 eyes) with mean age of 40 years. Subjective DED was detected in 77%, objective in 89.2%, and definite in 67.7% of the eyes. Severe subjective and objective DED were found in 36.5% and 24.3% of the eyes, respectively. TBUT was the most frequent positive test (63.5%). MGD was observed in 56.8% of the eyes. Mean clinical activity score, palpebral fissure, rundle grading, proptosis, corneal aesthesiometry, and presence of MGD were not significantly different between the eyes with and without subjective, objective, or definite DED. CONCLUSION: Definite DED was found in more than 2/3 of the eyes with moderate severe TED. While frequency of objective DED was higher, severe form of subjective DED was more frequent. No variable was significantly different between the eyes with and without subjective, objective and definite DED.

AB - INTRODUCTION: The application of intraoperative radiation therapy to the tumor bed after resection of pancreatic cancer has been shown to be beneficial in the local control of the disease. The objective of this study was to evaluate the preliminary outcomes after the application of a single intraoperative dose to the tumor bed with a new intraoperative radiotherapy device (Intrabeam(r)) in terms of viability, safety and short-term results. METHODS: We studied 5 patients who underwent pancreaticoduodenectomy for resectable pancreatic cancer in which a radiotherapy boost (5Gy) was intraoperatively applied to the tumoral bed using the portable Intrabeam(r) device, a low-energy point-source X-ray. Postoperative complications, hospital stay and mortality, recurrences and short-term survival were analyzed. RESULTS: Mean patient age was 68 years. All patients had a T3 stage tumor and one of them N1. In 3 patients, R0 resection was performed, while R1 resection was conducted in 2. Perioperative mortality was 0%. The only complications included delayed gastric emptying and postoperative hemorrhage. There were no pancreatic fistulas. During follow-up (mean: 11.2 months), there was a relapse in the patient who had undergone R1 resection. CONCLUSIONS: The application of radiotherapy with the Intrabeam(r) device in selected patients has not resulted in increased perioperative morbidity or mortality; therefore, this is a safe procedure for the treatment of resectable cancer. PMID- 30297033 TI - Abdominal eventration with massive visceral content. PMID- 30297035 TI - The added value of contrast-enhanced ultrasound to conventional ultrasound in differentiating benign and malignant solid breast lesions: a systematic review and meta-analysis. AB - AIM: To investigate the added value of contrast-enhanced ultrasound (CEUS) to the conventional ultrasound (US) in the diagnosis of breast lesions. MATERIALS AND METHODS: PubMed, EMBASE, and Web of Science were searched for relevant studies published between 24 May 2005, and 29 October 2017. Studies incorporating CEUS into the conventional US were included. The reference standard was set by means of histopathological findings. The quality assessment of diagnostic studies (QUADAS) instrument was used to assess the quality of the included studies. Meta Disc version 1.4. was used to calculate the sensitivity, specificity, summary receiver-operating characteristic (sROC) curves, and area under the curve (AUC). Meta-regression with Stata 12.0 was used to compare the diagnostic accuracy of the two techniques. RESULTS: Five studies, comprising 992 patients, were eligible for this meta-analysis. For conventional US, the pooled sensitivity and specificity for were 0.87 (95% confidence interval [CI]: 0.84-0.91) and 0.80 (95% CI: 0.76-0.84), respectively, the AUC was 0.9049. For CEUS-rerated US, the pooled sensitivity and specificity were 0.93 (95% CI: 0.90-0.95) and 0.87 (95% CI: 0.84 0.90). The AUC was 0.9482. Meta-regression showed the sensitivity of CEUS-rerated US did not differ from conventional US (p=0.29), while specificity showed significant difference (p<0.01). There was evidence of between-study heterogeneity regarding sensitivity and specificity for both assessments. CONCLUSIONS: Adding CEUS to conventional US could improve the diagnostic performance in differentiating benign from malignant solid breast lesions, whilst retaining high sensitivity, especially in Breast Imaging-Reporting and Data System (BI-RADS) 3-5 lesions. A uniform standard to distinguish benign from malignant lesions might be needed for further clinical application. PMID- 30297034 TI - Quality of recovery after surgery for cancer treatment. AB - INTRODUCTION: Assessment of quality of recovery is important as an end-point for outcome research. This study aims to determine the incidence and determinants of poor quality of recovery (PQR) after surgery in patients scheduled for curative neoplastic surgery. MATERIALS AND METHODS: An observational prospective study was performed in consecutive patients undergoing surgery for cancer treatment. The Quality of Recovery 15 score (QoR-15) was applied on the day before surgery (T0) and 24h after (T1). PQR was defined for patients with a QoR-15 score lower than the mean QoR-15 score at T1 minus one standard deviation. Preoperative quality of life was assessed with EuroQol-5D. Frailty and disability were defined using Clinical Frailty Scale and World Health Organization Disability Assessment Schedule 2.0. RESULTS: One hundred and thirty-eight patients were enrolled and 31 (15.9%) were identified as having PQR. At T0, patients with PQR presented lower scores on total QoR-15 (P=.03) and had more problems on EuroQol-5D in mobility (P=.014), self-care (P=.027) and usual activities domains (P=.019). The difference of QoR-15 score between T1 and T0 was higher in PQR patients (P<.001). PQR had more frequently Revised Cardiac Risk Index (RCRI)>=2 (P=.012) and were more frequently frail (P=.03). PQR patients stayed longer in the hospital (P=.034). CONCLUSION: PQR patients had lower QoR-15 before surgery, poor quality of life, were more frequently frail and had high cardiac risk factors. PQR patients stayed longer in the hospital. PMID- 30297036 TI - Design analysis indicates Potential overestimation of treatment effects in randomized controlled trials supporting Food and Drug Administration cancer drug approvals. AB - OBJECTIVE: Statistical significance drives interpretation of randomized controlled trials (RCTs). We examined the type S error risk-claiming a new drug is falsely beneficial-and exaggeration ratio-how estimated effects differ from true effects-to re-emphasize direction and magnitude of treatment effects. STUDY DESIGN AND SETTING: We systematically reviewed RCTs supporting Food and Drug Administration (FDA) approval of cancer drugs between 2007 and 2016. We extracted data for overall survival (OS), progression-free survival (PFS), and response outcomes from FDA reviews. We estimated type S error risks and exaggeration ratios by considering replicated RCTs of equal size and a range of true effects. RESULTS: We analyzed 42 RCTs for 39 approved drugs. Across 38 RCTs reporting OS, the median type S error risk was 0.00% (Q1-Q3, 0.00-0.01%) and 3.56% (0.40 6.74%), for true hazard ratios of 0.7 and 0.9, respectively, indicating confidence in effect direction. The corresponding exaggeration ratios were 1.09 (1.01-1.11) and 1.30 (1.13-1.42), indicating median overestimations of 9% and 30%. Similar results held for PFS and response outcomes. CONCLUSIONS: The type S error risk and exaggeration ratio provide additional insights into the replicability of RCTs. Our analyses also quantify the winner's curse, in which pivotal RCTs tend toward overoptimism. PMID- 30297037 TI - Improving the conduct of systematic reviews: a process mining perspective. AB - OBJECTIVES: To illustrate the use of process mining concepts, techniques, and tools to improve the systematic review process. STUDY DESIGN AND SETTING: We simulated review activities and step-specific methods in the process for systematic reviews conducted by one research team over 1 year to generate an event log of activities, with start/end dates, reviewer assignment by expertise, and person-hours worked. Process mining techniques were applied to the event log to "discover" process models, which allowed visual display, animation, or replay of the simulated review activities. Summary statistics were calculated for person time and timelines. We also analyzed the social networks of team interactions. RESULTS: The 12 simulated reviews included an average of 3,831 titles/abstracts (range: 1,565-6,368) and 20 studies (6-42). The average review completion time was 463 days (range: 289-629) (881 person-hours [range: 243-1,752]). The average person-hours per activity were study selection 26%, data collection 24%, report preparation 23%, and meta-analysis 17%. Social network analyses showed the organizational interaction of team members, including how they worked together to complete review tasks and to hand over tasks upon completion. CONCLUSION: Event log and process mining can be valuable tools for research teams interested in improving and modernizing the systematic review process. PMID- 30297038 TI - Advanced imaging modalities to detect cardiotoxicity. AB - Recent advances in cancer treatments have significantly improved survival rates, reemphasizing the focus on reducing the potential complications associated with some therapies. Cardiovascular disease associated with chemotherapies is a major cause of morbidity and mortality in cancer survivors. Early detection of cardiotoxicity improves cardiac outcomes among cancer patients. The review will focus on imaging modalities used to assess cardiotoxicity - the cardiovascular consequences of chemotherapies. The review will discuss the benefits and limitations associated with each technique, as well as the guidelines available to help identify at risk patients. We will discuss novel techniques that may help detect earlier signs of cardiotoxicity, directing management that may improve clinical outcomes. PMID- 30297039 TI - Does only the age of the hen matter in Salmonella enterica contamination of eggs? AB - Contamination of eggs with Salmonella enterica is a significant risk factor contributing to foodborne disease. Periods of peak egg contamination were identified by conducting longitudinal environmental and egg sampling in 7 layer flocks until they were 50 weeks of age. A total of 714 environmental samples and 8958 eggs were cultured using standard methods for the detection of salmonellae. Pooled egg contamination with Salmonella Typhimurium or Salmonella Infantis was detected at a true prevalence (TP) of 0.002 (95% CI = 0.001, 0.004) or 0.005 (95% CI = 0.004, 0.007), respectively. S. Typhimurium and S. Infantis were detected in individual egg components; in shell rinse at a TP of 0.014 (95% CI = 0.005, 0.038), in shell and membrane at a TP of 0.01 (95% CI = 0.003, 0.032), and in albumen and yolk content at a TP of 0.007 (95% CI = 0.001, 0.027). The concentration of salmonellae in all fractions was <1 CFU/mL. The TP of Salmonella enterica in eggs was highest at the onset of lay. Higher egg prevalence was associated with a lower body weight, higher egg production, higher egg weight and mass than the breed standard for age, and poorer feed conversion efficiency. Flock physiology appears to have an important influence on the detection of eggs contaminated with Salmonella enterica. PMID- 30297040 TI - Assessment of the non-lactic acid bacteria microbiota in fresh cucumbers and commercially fermented cucumber pickles brined with 6% NaCl. AB - Limited documentation of the cucumber fermentation microbiome has impeded the understanding of the role of microbes on the quality of finished products. We characterized the microbiome of fresh and fermented cucumber samples using culture dependent and independent techniques, with an emphasis on the non-lactic acid bacteria (non-LAB) population. Insubstantial microbiome variations were observed among fresh cucumber types with Rhizobium (31.04%), Pseudomonas (14.08%), Pantoea (9.25%), Stenotrophomonas (6.83%), and Acinetobacter (6.5%) prevailing. The relative abundance of LAB remained below 0.4% and 4.0% on fresh cucumbers and day 3 of the fermentations brined with 6% sodium chloride, respectively. Fermentation cover brine samples collected on day 1 harbored Pseudomonas, Pantoea, Stenotrophomonas, Acinetobacter, Comamonas, Wautersiella, Microbacterium, Flavobacterium, Ochrobactrum and the Enterobacteriaceae, Citrobacter, Enterobacter and Kluyvera. Plate counts for presumptive Klebsiella and Pseudomonas from fermentation cover brine samples reached 2.80 +/- 0.36 and 2.78 +/- 0.83 log of CFU/mL, respectively, in 30% and 60% of the nine tanks scrutinized with selective media. Both genera were found in cover brine samples with pH values at 4.04 +/- 0.15. We aim at elucidating whether the low relative abundance of non-LAB in commercial cucumber fermentations, in particular Pseudomonas and Enterobacteriaceae, impacts the quality of fermented cucumbers. PMID- 30297041 TI - Microbial characterisation of the edible grasshopper Ruspolia differens in raw condition after wild-harvesting in Uganda. AB - This research aimed at establishing the chemical intrinsic properties and the microbial quality of an edible grasshopper Ruspolia differens and the effect of its source (geographical area) in Uganda, trading point, swarming season and plucking on these parameters. The intrinsic properties of the grasshopper can support the growth of a wide variety of microorganisms. High counts of total aerobic microbes, Enterobacteriaceae, lactic acid bacteria, total aerobic spores, and yeasts and moulds were obtained. Metagenetic analyses yielded 1793 Operational Taxonomic Units (OTUs) belonging to 24 phyla. Actinobacteria, Bacteroidetes, Firmicutes, Fusobacteria and Proteobacteria were the most abundant phyla, while members of the genera Acinetobacter, Buttiauxella, Lactococcus, Staphylococcus and Undibacterium were the most abundant OTUs. A number of genera harbouring potential pathogens (Acinetobacter, Bacillus, Buttiauxella, Campylobacter, Clostridium, Staphylococcus, Pseudomonas and Neisseria) were identified. The geographical area, trading point, swarming season and plucking significantly influenced microbial counts and bacterial diversity. The high microbial counts predispose R. differens to fast microbial spoilage, while the presence of Clostridium and Campylobacter makes this grasshopper a potential source of food borne diseases. Further research should identify the specific spoilage microorganisms of R. differens and assess the characteristics of this grasshopper that support growth of food pathogens. PMID- 30297042 TI - A review of Clostridioides [Clostridium] difficile occurrence through the food chain. AB - The epidemiology and transmission of Clostridioides difficile, particularly for community-associated infections, are not completely understood. Although there have been no confirmed cases of any foodborne disease caused by C. difficile, its occurrence in livestock and foods suggests that contaminated food products with spores could be a vehicle to spread C. difficile infection. This review proposes potential sources of C. difficile infection in the community and contamination routes of food products. Based on European research, it also summarizes the occurrence and organism characterization of C. difficile in animals at slaughterhouses and in human foods. Most of the analyzed literature reported prevalence in retail foods of less than 8%, including microorganism belonging to the ribotype 078, an important hypervirulent strain involved in disease in humans. This prevalence in Europe is underestimated, being lower that reported in North America (rates up to 42%), probably due of the lack of an ISO procedure for the detection of C. difficile in food products that preclude the comparison of prevalence data from different studies. The survival and growth of vegetative C. difficile cells and the resistance of its spores in foods are discussed as well as the risk factors of acquisition CDI from food products. PMID- 30297043 TI - Sequential treatment of hydrogen peroxide, vacuum packaging, and dry heat for inactivating Salmonella Typhimurium on alfalfa seeds without detrimental effect on seeds viability. AB - The aim of this study was to inactivate Salmonella Typhimurium loaded onto alfalfa seeds with sequential treatment of hydrogen peroxide, drying, vacuum packaging, and dry heat. Also, we verified the effect of vacuum packaging in dry heat treatment. Populations of Salmonella on alfalfa seeds after sequential treatment were not detected after 8 or 3 h of dry heat treatment at 70 or 73 degrees C. Salmonella populations including injured cells were also reduced to below the detection limit after 8 or 4 h of dry heat treatment. The germination rate of alfalfa seeds subjected to the harshest treatment was not significantly different (P > 0.05) from that of untreated seeds. Vacuum packaging is conducive to preserving the moisture content of alfalfa seed and improving the efficiency of dry heat treatment. This study suggests that sequential treatment is recommended and applicable for decontaminating alfalfa seeds for sprout production. PMID- 30297044 TI - Evaluation of sampling methods for the detection of pathogenic bacteria on pre harvest leafy greens. AB - Recent outbreaks of foodborne disease associated with leafy greens have led to increased pre-harvest testing for pathogens and indicator microorganisms. However, the scientific and statistical rationale and the performance attributes for pre-harvest sampling methods are not well understood. The performance of three pre-harvest sampling methods, random, stratified random, and Z-pattern sampling, was evaluated by consideration of their mathematical derivations, computer simulations and field validation. Consideration of the probabilistic basis of the sampling methods indicated that the mean detection rates were similar. However, use of simulation modeling to assess the uncertainty associated with the three sampling methods indicated that the inherent variability of the Z pattern sampling method was substantially greater than the other two sampling methods. A simulation tool was developed in Matlab that allowed the evaluation of the effectiveness of the three sampling methods. A limited validation study also observed that Z-pattern sampling had higher variability than the other two sampling methods. This study indicates that while the mean detection probabilities for the three sampling methods are similar, the random or stratified random sampling are less variable, particularly when the number of contamination sites or number of samples analyzed are small. PMID- 30297045 TI - Genomic and metabolic features of the Bacillus amyloliquefaciens group- B. amyloliquefaciens, B. velezensis, and B. siamensis- revealed by pan-genome analysis. AB - The genomic and metabolic features of the Bacillus amyloliquefaciens group comprising B. amyloliquefaciens, B. velezensis, and B. siamensis were investigated through a pan-genome analysis combined with an experimental verification of some of the functions identified. All B. amyloliquefaciens group genomes were retrieved from GenBank and their phylogenetic relatedness was subsequently investigated. Genome comparisons of B. amyloliquefaciens, B. siamensis, and B. velezensis showed that their genomic and metabolic features were similar; however species-specific features were also identified. Energy metabolism-related genes are more enriched in B. amyloliquefaciens, whereas secondary metabolite biosynthesis-related genes are enriched in B. velezensis. Compared to B. amyloliquefaciens and B. siamensis, B. velezensis harbors more genes in its core-genome which are involved in the biosynthesis of antimicrobial compounds, as well as genes involved in d-galacturonate and d-fructuronate metabolism. B. amyloliquefaciens, B. siamensis, and B. velezensis all harbor a xanthine oxidase gene cluster (xoABCDE) in their core-genomes that is involved in metabolizing xanthine and uric acid to glycine and oxalureate. A reconstruction of B. amyloliquefaciens group metabolic pathways using their individual pan genomes revealed that the B. amyloliquefaciens group strains have the ability to metabolize diverse carbon sources aerobically, or anaerobically, and can produce various metabolites such as lactate, ethanol, acetate, CO2, xylitol, diacetyl, acetoin, and 2,3-butanediol. This study therefore provides insights into the genomic and metabolic features of the B. amyloliquefaciens group.

AB - Utilization of carbohydrates and amino acids/ammonium by selected non Saccharomyces yeasts and impacts on alcoholic fermentation was evaluated using media and high sugar grape musts (>270 g/L). Consumption patterns of single cultures were ascertained in synthetic media and a Chardonnay grape must. While the non-Saccharomyces species maintained >106 cfu/mL after >40 days, concentrations of residual sugars ranged from 103 g/L (Wickerhamomyces anomalus) to 155 g/L (Candida californica), amino acids and ammonium were generally depleted (>85%), and excessive amounts of volatile acidity (>0.8 g/L) were sometimes produced (e.g., C. oleophila). To minimize problems associated with nutrient depletion before alcoholic fermentation, non-Saccharomyces yeasts were inoculated six days ahead of S. cerevisiae into Syrah grape musts. Syrah ferments inoculated with C. californica or Metschnikowia pulcherrima contained lower concentrations of residual sugar and ethanol compared to those with only S. cerevisiae. Furthermore, the presence of non-Saccharomyces yeasts influenced concentrations of glycerol and volatile aroma compounds. These results suggested potential use of some non-Saccharomyces yeasts towards reducing alcohol concentrations without risking slower alcoholic fermentations. PMID- 30297047 TI - Comparative evaluation of spoilage-related bacterial diversity and metabolite profiles in chilled beef stored under air and vacuum packaging. AB - Microbial spoilage is a complex event to which different bacterial populations and metabolites can contribute depending on the storage conditions. This study explored the evolution of spoilage and related volatile organic compounds (VOCs) in chilled beef under air and vacuum packaging (VP). The results suggested that different storage conditions affected changes in bacterial communities and metabolites in beef and consequently affected the odor properties of the stored beef, thereby leading to spoilage. Bacterial species belonging to Pseudomonadaceae (Pseudomonas spp.) and lactic acid bacteria (Lactobacillus sp.) dominated the bacterial communities in beef stored under air and VP, respectively, with several VOCs associated with off-odors of the stored beef and most likely produced by both bacteria. Our results suggested several microbial VOCs that could be used as potential spoilage indicators, including acetic acid, butanoic acid, and 2-butanone in VP-stored beef and 3-methylbutan-1-ol, ethyl acetate, acetoin, 2-butanone, and diacetyl in air-stored beef. These findings might provide valuable information regarding the quality monitoring of beef during storage. PMID- 30297048 TI - Evaluation of post-contamination survival and persistence of applied attenuated E. coli O157:H7 and naturally-contaminating E. coli O157:H7 on spinach under field conditions and following postharvest handling. AB - This study determined the variability in population uniformity of an applied mixture of attenuated E. coli O157:H7 (attEcO157) on spinach leaves as impacted by sampling mass and detection technique over spatial and temporal conditions. Opportunistically, the survival and distribution of naturally contaminating pathogenic E. coli O157:H7 (EcO157), in a single packaged lot following commercial postharvest handling and washing, was also evaluated. From the main study outcomes, differences in the applied inoculum dose of 100-fold, resulted in indistinguishable population densities of approximately Log 1.1 CFU g-1 by 14 days post-inoculation (DPI). Composite leaf samples of 150 g and the inclusion of the spinach petiole resulted in the greatest numerical sensitivity of detection of attEcO157 when compared to 25 and 150 g samples without petioles (P < 0.05). Differences in population density and protected-site survival and potential leaf internalization were observed between growing seasons and locations in California (P < 0.05). A Double Weibull model best described and identified two distinct populations with different inactivation rates of the inoculated attEcO157. Linear die-off rates varied between 0.14 and 0.29 Log/Day irrespective of location. Detection of EcO157- stx1-negative and stx2-positive, resulting from a natural contamination event, was observed in 11 of 26 quarantined commercial units of washed spinach by applying the 150 g sample mass protocol. The capacity to detect EcO157 varied between commercial test kits and non-commercial qPCR. Our findings suggest the need for modifications to routine pathogen sampling protocols employed for lot acceptance of spinach and other leafy greens. PMID- 30297049 TI - Contamination of chicken meat with extended-spectrum beta-lactamase producing- Klebsiella pneumoniae and Escherichia coli during scalding and defeathering of broiler carcasses. AB - Extended-spectrum beta-lactamase- (ESBL-) producing Klebsiella (K.) pneumoniae and Escherichia (E.) coli are of critical importance in human and veterinary medicine. Animal food products, especially broiler chickens, are discussed as a possible source for the exposure of humans with antibiotic resistant bacteria. Although the occurrence and vertical transmission of ESBL-/AmpC-producing Enterobacteriaceae in the broiler production has been reported before, detailed investigations concerning the dissemination along the slaughter processing line are missing. In this study, we investigated cross-contamination with ESBL producing Enterobacteriaceae during the processing of two different broiler flocks in one slaughterhouse. The ESBL-status during the fattening period of the flocks was determined and environmental samples from the slaughterhouse were taken before processing of the respective flocks. These isolates were compared to those found in samples from the carcasses after processing using whole genome sequencing. Phylogenetic analyses of seven ESBL-producing K. pneumoniae and 14 E. coli revealed close relationships between isolates from scalding water and the defeathering machine, respectively, which were collected before the processing of the broiler flocks, to those isolates found in samples from skin and filet of the respective flock carcasses. In conclusion, using high resolution molecular data we found evidence for the cross-contamination of carcasses with ESBL-producing Enterobacteriaceae during scalding and defeathering in the slaughterhouse. PMID- 30297050 TI - Global transcriptomic response of Listeria monocytogenes during growth on cantaloupe slices. AB - Understanding a pathogen's response to food environments is imperative to develop effective control strategies as well as to elucidate the impact of foods on virulence potential. The purpose of this study was to assess transcriptional response of Listeria monocytogenes after growth in cantaloupe, as well as its impact on survival in synthetic gastric fluid (SGF). The transcriptional profiles of L. monocytogenes grown in cantaloupe or Brain Heart Infusion (BHI) under refrigeration were compared by a custom-designed microarray. A total of 286 and 175 genes were significantly up- and down-regulated, respectively, in L. monocytogenes grown in cantaloupe as compared to BHI (fold change >= 2.5 and adj. P < 0.05). The majority of upregulated genes belonged to functions related to amino acid and nucleotide metabolism, flagellar biosynthesis, and iron acquisition, while most downregulated genes belonged to carbohydrate metabolism. Notably, the branched chain amino acid (BCAA: leucine, isoleucine, valine) biosynthesis operon was shown to be highly upregulated as well as the purine and pyrimidine biosynthesis pathways. Transcript levels of several stress- and virulence-related genes were significantly altered, implying an impact of growth in cantaloupe on the virulence potential of L. monocytogenes. Enhanced survival of L. monocytogenes in SGF following growth in cantaloupe further demonstrated the impact of cantaloupe-associated growth on the pathogen's subsequent response to a host relevant stress. PMID- 30297051 TI - Survival of clinical and food Acinetobacter spp. isolates exposed to different stress conditions. AB - Acinetobacter baumanni is recognized as one of the most important agents of nosocomial infections. Other species such as Acinetobacter lwoffii have also been associated with such infections. These species can be found in food products, such as vegetables, fruits and meats which can be a source of transmission of these organisms to community and hospital settings. Evidence that hospitals' kitchens are a route of entry of pathogenic and antimicrobial-resistant bacteria was recently demonstrated. This study aimed to determine whether different Acinetobacter spp. isolated from human and food samples (lettuce, turkey meat, apple and pear) were resistant to stress conditions often applied in food processes, such as exposure to 60 degrees C, AMUKINA(r) and vinegar. Also the influence of food matrices on the behavior of isolates to these stress conditions was evaluated. Treatment with AMUKINA(r) and vinegar were effective against all clinical and food isolates. Exposure to 60 degrees C resulted in the reduction of the majority of isolates to values below the detection limit of the enumeration technique, however, it is important to note that most of the reductions only occurred after 30 min of exposure. One food isolate identified as A. baumanni was resistant to this thermal treatment and one clinical isolate only decreased 4 log cycles after 1 h. In general, food isolates were demonstrated to be more resistant than clinical isolates and no significant differences (p > 0.05) were found between A. baumanni and A. lwoffii species. With the exception of one food isolate that was more resistant to thermal stress in the presence of turkey meat, the food matrices investigated did not confer protection to the applied stresses. Due to the limited knowledge on this topic, we believe that this study is an important contribution to understanding the behavior of Acinetobacter spp. when exposed to treatments commonly applied to foods. PMID- 30297052 TI - Modelling the effect of oxygen concentration on bacterial growth rates. AB - Predicting the microbial safety of food products stored in modified atmosphere packaging implies taking into account the effect of oxygen reduction on microbial growth. According to their respiratory-type, the micro-organisms are not impacted similarly by the oxygen concentration. The aim of this article was to quantify and model the oxygen effect on the growth rates of 5 bacterial species: Listeria monocytogenes and Bacillus weihenstephanensis (facultative anaerobic), Pseudomonas fluorescens (strict aerobic), Clostridium perfringens and Clostridium sporogenes (strict anaerobic). The results showed the oxygen concentration doesn't modify the behavior of both facultative anaerobic strains. The growth rate of P. fluorescens decreased with the oxygen concentration, but the effect is only noticeable when the oxygen concentration fell below 3% in the gaseous phase. Conversely, the oxygen acted as a growth inhibitor for both Clostridium species. But total inhibition is reached only for 3.26% and 6.61% respectively for C. sporogenes and C. perfringens. Two models have been fitted for both respiratory types, the first is the Monod model considering oxygen as a substrate for growth, and the second is the classic inhibitory model based on minimal inhibitory concentration. PMID- 30297053 TI - Changes in the microbial communities in vacuum-packaged smoked bacon during storage. AB - This study aimed to gain deeper insights into the microbiota composition and population dynamics, monitor the dominant bacterial populations and identify the specific spoilage microorganisms (SSOs) of vacuum-packed bacon during refrigerated storage using both culture-independent and dependent methods. High throughout sequencing (HTS) showed that the microbial composition changed greatly with the prolongation of storage time. The diversity of microbiota was abundant at the initial stage then experienced a continuous decrease. Lactic acid bacteria (LAB) mainly Leuconostoc and Lactobacillus dominated the microbial population after seven days of storage. A total of 26 isolates were identified from different growth media using traditional cultivation isolation and identification method. Leuconostoc mesenteroides and Leuconostoc carnosum were the most prevalent species since day 15, while Lactobacillus sakei and Lactobacillus curvatus were only found on day 45, suggesting that they could be responsible for the spoilage of bacon. Serratia, Rahnella, Fusobacterium and Lactococcus underwent a dramatic increase at some point in individual batchs which may be considered as potential contributors to the spoilage. PMID- 30297054 TI - Spoilage indicator bacteria in farmed Atlantic salmon (Salmo salar) stored on ice for 10 days. AB - This study investigated the growth of indicator and spoilage bacteria on whole Atlantic salmon (Salmo salar) stored aerobically at 2 degrees C. On days 0, 2, 3, 6, 8 and 10 microbiological analysis was carried out on inner flesh and outer skin samples as well as outer skin swabs (25 cm2 surface areas). Mesophilic total viable counts (TVCm) on skin, flesh and swab samples increased from 1.9, 1.1 and 2.7 log10 CFUcm2 to 6.0, 5.1 and 5.7 log10 CFU/cm2 after 10 days, respectively. Psychrotrophic counts (TVCp), increased from 2.2, 1.8 and 3.1 log10 CFU/cm2 to 6.2, 5.3 and 5.9 log10 CFU/cm2, for skin, flesh and swab samples respectively. Hydrogen sulphide producing bacteria (HSPB), lactic acid bacteria (LAB), Pseudomonas spp., Brochothrix thermosphacta and Photobacterium spp. grew well with similar growth rates (mean generation times of 17.2-26 h). It was concluded that the shelf-life of salmon at 2 degrees C was approximately 10 days and that HSPB, LAB, Pseudomonas spp., Br. thermosphacta and Photobacterium spp. may be a better indicator of fish spoilage rather than TVC growth, with a count of 5-6 log10 CFU/cm2 indicating the end of shelf-life. PMID- 30297055 TI - Metabolism of phenolic acids in whole wheat and rye malt sourdoughs. AB - This work aimed to study the phenolic acid metabolism of sourdough lactic acid bacteria (LAB) in laboratory media, and in sourdough fermentation with single cultures and in co-fermentations. Lactobacilli were selected from isolates obtained from 35 sourdough samples. Isolates (114 strains) were screened for phenolic acid decarboxylase gene pdc and EPS production. Ferulic acid metabolism of the 18 pdc positive strains was evaluated in mMRS; all pcd positive strains converted ferulic acid by decarboxylation and/or reduction. Single whole wheat and rye malt dough fermentation fermented with lactobacilli or yeasts were characterized with respect to free, conjugated, or bound phenolic acids. Concentrations of free, conjugated, or bound phenolic acids were not altered substantially in chemically acidified sourdoughs, or in yeast fermented doughs. L. plantarum metabolized free ferulic acid in wheat and rye malt sourdoughs; L. hammesii DSM 16381 metabolized syringic and vanillic acids and reduced levels of bound ferulic acid in wheat sourdoughs. Co-fermentation of L. hammesii and L. plantarum achieved release of bound ferulic acid and conversion of the resultant free ferulic acid to dihydroferulic acid and volatile metabolites. Phenolic acid metabolism in sourdoughs was enhanced by co-fermentation with strains exhibiting complementary metabolic activities. Results may enable improvement of bread quality by targeted conversion of phenolic acids during sourdough fermentation. PMID- 30297056 TI - Effective inhibition of Salmonella Typhimurium in fresh produce by a phage cocktail targeting multiple host receptors. AB - Salmonella contamination of fresh produce is the primary bacterial cause of a significant number of foodborne outbreaks and infections. Bacteriophages can be used as natural antibacterial agents to control foodborne pathogens. However, the rapid development of bacterial resistance to phage infection is a significant barrier to practical phage application. To overcome this problem, we developed a novel phage cocktail consisting of the three phages (BSPM4, BSP101 and BSP22A) that target different host receptors, including flagella, O-antigen and BtuB, respectively. Whole genome sequence analysis of the phages revealed that three phages do not harbor genes involved in lysogen formation or toxin production, suggesting they are safe for use as biocontrol agents in foods. In vitro treatment of the phage cocktail resulted in a significant reduction in the development of bacterial resistance. Phage cocktail treatments achieved 4.7-5.5 log CFU/cm2 reduction of viable cell number in iceberg lettuce and 4.8-5.8 log CFU/cm2 reduction in cucumber after 12 h at room temperature (25 degrees C). The phage cocktail exhibited good antimicrobial efficiency, suggesting that it could reduce S. Typhimurium contamination of fresh produce. The strategy of developing cocktails of phages that target multiple host receptors can be used to develop novel biocontrol agents of S. Typhimurium. PMID- 30297057 TI - In situ riboflavin fortification of different kefir-like cereal-based beverages using selected Andean LAB strains. AB - Cereal-based functional beverages represent social, economic, and environmental sustainable opportunities to cope with emerging trends in food consumption and global nutrition. Here we report, for the first time, the polyphasic characterization of three cereal-based kefir-like riboflavin-enriched beverages, obtained from oat, maize and barley flours, and their comparison with classical milk-based kefir. The four matrices were successfully fermented with commercial starters: i) milk-kefir and ii) water-kefir, proving the potential of cereal ingredients in the formulation of dairy-like fermented beverages with milk-kefir starter behavior better in these matrices. In the light of their potentiality, seven riboflavin-producing Andean Lactic Acid Bacteria (LAB) were tested for tolerance to food stresses commonly encountered during food fermentation. Moreover, the LAB strains investigated were screened for spontaneous riboflavin overproducing derivatives. Lactobacillus plantarum M5MA1-B2 with outstanding response to stress, was selected to improve riboflavin content in an in situ fortification approach. The combination of L. plantarum M5MA1-B2 riboflavin overproducing strain with milk kefir starter in oat, lead to cover, for one serving of 100 g, 11.4% of Recommended Dietary Allowance (RDA). Besides, addition of L. plantarum M5MA1-B2 improved performance of water kefir in oat and maize matrices. Proton Transfer Reaction Time-of-Flight Mass Spectrometry (PTR-ToF-MS) analysis provided the on-line Volatile Organic Compounds profiles supporting the best combination of starter, LAB and cereal matrix for novel functional foods development. PMID- 30297058 TI - Effects of Enterococcus faecalis UGRA10 and the enterocin AS-48 against the fish pathogen Lactococcus garvieae. Studies in vitro and in vivo. AB - The aim of this study was to evaluate the effects of Enterococcus faecalis UGRA10 and its enterocin AS-48 against the fish pathogen Lactococcus garvieae. The minimum bactericidal concentrations of AS-48 against L. garvieae CECT 5807, 5806, and 5274 were 15.62, 15.62, and 7.81 MUg/ml respectively. In broth cultures, enterocin at 100, 50, and 25 MUg/ml reduced 108 CFU/ml lactococci after 2, 5, and 10 h, respectively. In co-cultures of UGRA10/L. garvieae at a 1/10 CFU/ml ratio, lactococci were eliminated after 24 h. Studies on UGRA10 biosafety and AS-48 toxicity in R1 cells and in rainbow trout have shown a lack of adverse effects from both the strain and bacteriocin. Trout challenged with L. garvieae and UGRA10 administered in diet 30 days before infection had a cumulative survival rate of 50% compared with 0% for control fish. Trout inoculated with the pathogen and treated by regular dipping in AS-48 baths had a survival rate of 60% after 20 days compared with that of untreated fish (0%). These results indicate the protective effect of the UGRA10 strain and the bacteriocin AS-48 against L. garvieae and the potential of these natural products as alternatives to antibiotics for controlling diseases in aquaculture. PMID- 30297059 TI - Survival of Listeria monocytogenes during in vitro gastrointestinal digestion after exposure to 5 and 0.5 % sodium chloride. AB - The food industry is under pressure to reduce the NaCl content in food, but the consequences on the ability of L. monocytogenes to survive in the human host and cause listeriosis is not known. In this study, a recently developed internationally harmonized static in vitro digestion (IVD) model was used to investigate the survival of L. monocytogenes in the gastric and intestinal phases after exposure to 5 or 0.5% NaCl. Six isolates from three Scandinavian foodborne listeriosis outbreaks, all related to NaCl containing foods, the EGDe reference strain and an EGDe mutant, deleted for the major stress regulator gene, sigB, were included. A ten-fold reduction of NaCl in the cultivation media significantly reduced the survival fraction of the EGDe strain in the IVD model while one of the clinical outbreak isolates showed a significantly increased survival fraction. Finally, the EGDe strain was able to attach and invade cultured HT-29 cells after passage through the IVD model. Altogether, these results suggest that a reduction of the NaCl content from 5 to 0.5% prior to exposure to the IVD model has the potential to cause a change in the relative survival fraction and that the effect is strain dependent. PMID- 30297060 TI - Development and application of a real-time polymerase chain reaction method for quantification of Escherichia coli in oysters (Crassostrea gigas). AB - Oysters are important mariculture species worldwide. Because of their filter feeding behaviors, oysters can accumulate microorganisms, including pathogens, from surrounding water and concentrate bacteria in high numbers. Rapid and suitable methods for quantification of Escherichia coli in oysters are necessary considering that oysters are perishable foods often consumed raw and some countries use E. coli as the regulatory limit. The objective of this study was to develop a qPCR method for quantification of E. coli in oysters. Additionally, different methods were evaluated for DNA extraction from oyster samples and the more reliable method was chosen. Primers and probe were designed targeting uidA gene of E. coli and shown to specifically amplify DNA from E. coli. Standard curves with bacterial DNA extracted from oysters samples artificially inoculated with E. coli were conducted. A good correlation was noticed when the qPCR method was compared to a culture method in oyster samples. This is the first report of a method exclusively developed for direct quantification of E. coli in oyster, the method showed to be suitable for quantification of E. coli in oysters and could be useful in routine analyses, as it requires less time than the culture method. PMID- 30297061 TI - Synthesis of prebiotic galactooligosaccharides from lactose and lactulose by dairy propionibacteria. AB - The potential of probiotic bacteria to produce prebiotic oligosaccharides by transgalactosylation has been minimally studied. In this work, we screened the beta-galactosidase (beta-gal) activity of dairy propionibacteria (PAB) isolated from Argentinean foods to select strains for the synthesis of oligosaccharides from lactose (GOS) and lactulose (OsLu). PAB, when grown in a medium with lactose as a carbon source, were disrupted, and the cell-free extracts were assayed for beta-gal activity. Nine strains grew on lactose and showed beta-gal activities from 0.27 to 2.60 U mL-1. Propionibacterium acidipropionici LET 120, the strain with the highest activity, was able to synthesize, using 30% lactose and lactulose at pH 6.5 and 45 degrees C, 26.8% of LET 120-GOS and 26.1% of LET 120 OsLu after 24 h. When they were tested as carbon sources for growth, P. acidipropionici LET 120 attained higher biomasses, MUmax and beta-gal activities at the expense of Aspergillus oryzae-OsLu, Vivinal(r)-GOS and lactulose compared to lactose or glucose. In addition, LET 120-GOS and LET 120-OsLu synthesized by PAB were prebiotic for some probiotic strains. For the first time, our results show the production of GOS and OsLu by dairy PAB, and these results encourage further studies on the optimization of the synthesis and structure characterization of the obtained oligosaccharides. PMID- 30297062 TI - The Evolution of Mechanical Circulatory Support. AB - The field of mechanical circulatory support (MCS) has evolved from earlier generation pulsatile-flow devices that were primarily used to support critically ill patients in the hospital to newer-generation continuous-flow devices that permit hospital discharge and resumption of normal life activities. The technology is used to bridge transplant-eligible patients and can be used for long-term support of patients who are transplant ineligible. Left ventricular assist devices are proved to improve long-term survival and quality of life for patients with advanced heart failure. Adverse events associated with MCS therapy remain the Achilles heel of the field and strategies to improve biocompatibility are ongoing. PMID- 30297063 TI - Continuous-Flow Device Engineering and Pump Technology.

The authors examine the energy transfer mechanics of centrifugal versus axial devices, and the impact of novel noncontact pump bearings. Furthermore, this article reviews the relationship between continuous-flow pump speed, flow, and pressure gradients across the device. Potential future advances in pump design with greater algorithmic responses to changes in patient physiology are also considered.

With the advancement of technology, surgical implant strategy continues to evolve, incorporating less-invasive approaches into the armamentarium of the experienced surgeon. PMID- 30297065 TI - Temporary Circulatory Support and Extracorporeal Membrane Oxygenation. AB - Cardiogenic shock (CS) refractory to conventional therapies continues to be a challenging medical syndrome, with poor prognosis and high complication and mortality rates. The application and use of temporary mechanical circulatory support (MCS) is a component in the treatment of CS patients and should be applied early in the presentation. Crucial to the success of their application, temporary MCS devices should be chosen based on degree of patient acuity and etiology of CS. Not all temporary MCS devices deliver the same degree of hemodynamic support and range from minimal support to systemic support via veno arterial extracorporeal membrane oxygenation. PMID- 30297066 TI - Candidate Selection for Durable Mechanical Circulatory Support. AB - Severe systolic dysfunction combined with symptoms of heart failure has a high rate of morbidity and mortality. Medical management remains the mainstay of therapy but mechanical circulatory support (MCS) is one of the treatment options for end-stage heart failure. The left ventricular assist device (LVAD) is the most common type of device used for durable MCS. There have been significant improvements in the technology, surgical technique, and patient management. There is not a single model that is able to accurately assess risk in these patients due to the variety of variables. It is essential to assess all risk in the decision-making process. PMID- 30297067 TI - Perioperative Management of the Right and Left Ventricles. AB - Left ventricular assist devices (LVADs) improve survival in select advanced heart failure patients and rates of LVAD implantation are growing. LVAD support carries significant morbidity and mortality with the greatest risk in the perioperative period. Strategies have evolved to minimize this risk. Medical and mechanical support is used for right and left ventricular optimization. Other strategies emphasize improving nutrition, hematologic abnormalities, infection risk, and renal function. Intraoperative approaches highlight anesthesia-related issues, management of concomitant valve disease, right ventricular failure, and weaning from cardiopulmonary bypass. Postoperative efforts concentrate on augmenting right ventricular function, supporting end-organ recovery, and quickly identifying complications.

AB - Continuous-flow (CF) left ventricular assist devices (LVADs) are a safe and durable therapeutic option for patients with advanced heart failure as a bridge to transplant or as destination therapy. Despite the remarkable technological advances in device design and increasing familiarity with the physiologic effects of CF, major complications such as gastrointestinal bleeding (GIB) continue to cause significant morbidity. The causes underlying CF-LVAD-related GIB are multifactorial. Accordingly, management strategies for CF-LVAD-related GIB encompass a wide range of therapeutic modalities. This article reviews the epidemiology, pathophysiology, risk factors, and treatment options for the management of this complex complication. PMID- 30297070 TI - Neurologic Events in Continuous-Flow Left Ventricular Assist Devices. AB - Although the growing use of continuous-flow left ventricular assist devices (LVADs) has improved the survival and quality of life of patients with stage D heart failure, ischemic and hemorrhagic cerebrovascular accidents remain one of the most-feared complications of this therapy and a significant source of disability, morbidity, and mortality. In this article, the authors aim to summarize the current data regarding the incidence/prevalence of both ischemic and hemorrhagic stroke in patients with continuous-flow LVADs, compare axial and centrifugal devices, and discuss the major risk factors for neurologic events that have been identified. PMID- 30297071 TI - Antithrombotic Strategies and Device Thrombosis. AB - Despite improvements in left ventricular assist device (LVAD) technology, bleeding and thrombotic complications are major concerns that adversely influence morbidity and mortality. Current antithrombotic therapy recommendations for LVAD thrombosis prophylaxis are largely derived from clinical device trials that implement a one-size-fits-all strategy. Objective serial laboratory-based assessment of thrombogenicity is needed to balance the risk of bleeding and thrombotic complications. Finally, the newest-generation device, the HeartMate 3, has been associated with lower levels of shear and reduced hemolysis that may mitigate thrombotic event occurrences. PMID- 30297072 TI - Impact of Mechanical Circulatory Support on Posttransplant Outcomes. AB - Mechanical circulatory support (MCS) has markedly improved the likelihood of transplant among patients with advanced heart failure. Transplant survival following MCS is similar for supported and unsupported recipients. Transplant survival is only reduced following left ventricle assist device (LVAD) support complicated by infection, total artificial heart support, and extracorporeal life support. Despite allosensitization and a higher incidence of vasoplegia syndrome, posttransplant survival for durable LVADs is similar to patients with inotropes alone at the time of transplant. MCS as a bridge to transplant offers significant benefits over waiting without support. PMID- 30297074 TI - Ambulatory Ventricular Assist Device Patient Management. AB - Understanding the ventricular assist device (VAD) patient pump interface and developing expertise in monitoring patients with a VAD are the goals of care in the ambulatory setting. The objective is to improve long-term outcomes. The purpose of expert, focused, routine outpatient surveillance is to facilitate the integration of pulseless, electrically dependent VAD patients into the community. Other goals of outpatient care include maximizing quality of life, maintaining equipment integrity, treating heart failure symptoms, monitoring for common VAD related complications, ensuring viability as a heart transplant candidate, consideration for patients implanted to become transplantable, and monitoring for possible cardiac recovery. PMID- 30297073 TI - Hemodynamic Pump-Patient Interactions and Left Ventricular Assist Device Imaging. AB - Left ventricular assist devices (LVAD) provide a durable option for patients with advanced hear failure. Axial and centrifugal pump physiology differs with regard to the relationship between pump inflow-outflow cannula pressure differential and flow, which results in device behavior that can vary drastically under different loading conditions. Ramp studies can aid the clinician in choosing the optimal speed to adequately unload the left ventricle. Advances in 3-dimensional echocardiography enhance the understanding of chamber geometry for both types of LVADs. Novel outflow graft imaging techniques have been developed to better characterize aortic insufficiency, which may be underestimated with current standard methods.

AB - Recent advances in mechanical circulatory support have allowed patients with end stage heart failure to be successfully bridged to heart transplantation or live for many years on continuous-flow left ventricular assist devices (CF-LVADs) as destination therapy. As survival and quality of life continue to improve and the number of patients supported by CF-LVADs continues to grow, utilization of different imaging modalities in the care for these patients has become an integral part of many heart failure centers. We review currently available imaging modalities, with a focus on echocardiography, that aid to diagnose and manage common adverse events associated with CF-LVADs. PMID- 30297076 TI - Right Ventricular Failure and Biventricular Support Strategies. AB - Some degree of right ventricular (RV) dysfunction can be observed in most patients with advanced heart failure assed for left ventricular assist device (LVAD) implantation. This article describes critical factors that need to be considered in the assessment of the RV before LVAD surgery. Further, detailed description of the most important perioperative management strategies to prevent (RV) dysfunction is included. Finally, the most commonly used temporary and permeant RV support strategies are discussed, including anatomic and physiologic challenges and barriers associated with the off-label use of continuous-flow LVAD pumps for the right-sided circulation.

AB - There are many randomized trials evaluating non-vitamin K oral anticoagulants (NOAC) in patients with atrial fibrillation ablation. VENTURE AF, RE-CIRCUIT, and recently AXAFA have evaluated the three main NOACs in this indication. Other studies such as ABRIDGE J and AEIOU complemented these results. The management of the anticoagulation in these patients is one of the subjects of the European Society of Cardiology guidelines, as well, as, the EHRA guide recently released. The purpose of this article is to summarize published studies and guidelines. PMID- 30297079 TI - Tribute to Dr Gorm Wagner, Founding Father of ISSM.

PMID- 30297081 TI - Isolation and characterization of a marine testosterone-degrading bacterium: Vibrio sp. N3. AB - Steroids, including testosterone, estrone, 17beta-estradiol, estriol and 17beta ethinyl estradiol, are harmful not only to the population dynamics of aquatic life forms but also to public health. In this study, a marine testosterone degrading bacterium (strain N3) was isolated from Nanao Island in the South China Sea. In addition, the strain could also use 17beta-estradiol (E2), 17beta-ethinyl estradiol (EE2), estriol (E3) or cholesterol as a sole carbon source. According to the 16S rRNA gene sequence analysis, strain N3 was identified as Vibrio sp. Further characterization showed that the strain is aerobic, gram-negative, and mobile and exhibits resistance to ampicillin, carbenicillin, penicillin and spectinomycin. For enhancing its capacity of testosterone degradation, the Plackett-Burman factorial design and the central composite design were used to optimize the culture condition. Under optimal conditions, 92% of testosterone was degraded by Vibrio sp. N3 in 48h.

AB - Deficiency of 25-hydroxyvitamin D (25[OH]D) is common in patients with chronic kidney disease stages 3 and 4 and is associated with poor outcomes. However, the evaluation and management of vitamin D deficiency in nephrology remains controversial. This article reports on the proceedings from a "controversies conference" on vitamin D in chronic kidney disease that was sponsored by the National Kidney Foundation. The report outlines the deliberations of the 3 work groups that participated in the conference. Until newer measurement methods are widely used, the panel agreed that clinicians should classify 25(OH)D "adequacy" as concentrations > 20ng/mL without evidence of counter-regulatory hormone activity (ie, elevated parathyroid hormone). The panel also agreed that 25(OH)D concentrations < 15ng/mL should be treated irrespective of parathyroid hormone level. Patients with 25(OH)D concentrations between 15 and 20ng/mL may not require treatment if there is no evidence of counter-regulatory hormone activity. The panel agreed that nutritional vitamin D (cholecalciferol, ergocalciferol, or calcifediol) should be supplemented before giving activated vitamin D compounds. The compounds need further study evaluating important outcomes that observational studies have linked to low 25(OH)D levels, such as progression to end-stage kidney disease, infections, fracture rates, hospitalizations, and all-cause mortality. We urge further research funding in this field. PMID- 30297083 TI - Urine Acidification After Ammonium Chloride. PMID- 30297084 TI - Visualizing immune responses of the airway mucosa. AB - The airway mucosa is the primary tissue site exposed to inhaled particulate matter, which includes pathogens and allergens. While most inhaled particles are eliminated from the airways via mucociliary clearance, some pathogens may penetrate the mucosal epithelial barrier and an effective activation of the mucosal immune system is required to prevent further pathogen spread. Similarly, inhaled environmental allergens may induce an aberrant activation of immune cells in the airway mucosa, causing allergic airway disease. During the last years, several investigators employed advanced microscopic imaging on both intravital and tissue explant preparations to observe the dynamic behavior of various immune cells within their complex tissue environment. In the respiratory tract, most imaging studies focused on immune responses of the alveolar compartment in the lung periphery. However, equally important immunological events occur more proximally in the mucosa of the conducting airways, both during infection and allergic responses, calling for a more detailed imaging analysis also at this site. In this review, I will outline the technical challenges of designing microscopic imaging experiments in the conducting airways and summarize our recent efforts in understanding airway mucosal immune cell dynamics in steady state conditions, during infection and allergy. PMID- 30297085 TI - Efficient Neural Coding in Auditory and Speech Perception. AB - Speech has long been recognized as 'special'. Here, we suggest that one of the reasons for speech being special is that our auditory system has evolved to encode it in an efficient, optimal way. The theory of efficient neural coding argues that our perceptual systems have evolved to encode environmental stimuli in the most efficient way. Mathematically, this can be achieved if the optimally efficient codes match the statistics of the signals they represent. Experimental evidence suggests that the auditory code is optimal in this mathematical sense: statistical properties of speech closely match response properties of the cochlea, the auditory nerve, and the auditory cortex. Even more interestingly, these results may be linked to phenomena in auditory and speech perception. PMID- 30297086 TI - Always keep an open mind. PMID- 30297088 TI - Surgical ablation explained.

AB - OXA-48-producing Klebsiellapneumoniae isolates often show growth of colonies within inhibition zones in carbapenem diffusion assays. The nature of these colonies was investigated in a series of clinical isolates of OXA-48-producing K. pneumoniae obtained in the context of a hospital outbreak, and they were found to be persistent colonies that reproduced again the same phenotype when they were collected and tested in diffusion assays again. The frequency of mutations conferring resistance to meropenem (8 MUg/mL) was determined for the same isolates. The average mutation frequency was 5.47.10-6 (range: 2.59.10-8-5.87.10 5), and the analysis of several resistant mutants showed that all of them had mutations in the ompK36 porin gene. Heteroresistance was investigated using population analysis profiling. The profiles were compatible with mutation frequency assays, and all the colonies analyzed were resistant mutants. In OXA-48 producing K. pneumoniae, the growth of persisters seems to be specific of diffusion assays. PMID- 30297094 TI - Mindfulness-Based Group Therapy for Men With Situational Erectile Dysfunction: A Mixed-Methods Feasibility Analysis and Pilot Study. AB - INTRODUCTION: Recent advances in sexual health research support the benefits of mindfulness-based therapy (non-judgmental present-moment awareness) for the treatment of women's sexual dysfunction. AIM: To determine whether it is feasible to implement an adapted, empirically supported treatment protocol for female sexual dysfunction to the specific needs of men with situational erectile dysfunction (ED). METHODS: A mixed-methods approach was taken for this feasibility pilot study. A total of 10 men (Mage = 40.3, SD = 14.01, Range = 20 67) with a diagnosis of situational ED were recruited to participate in a 4-week mindfulness-based treatment group. The group was adapted from protocols shown to be effective for women with sexual dysfunction and edited to include content specific to situational ED. Sessions were 2.25 hours in length, included daily home-practice activities, and integrated elements of psychoeducation, sex therapy, and mindfulness skills. Men completed questionnaires (International Index of Erectile Functioning, Relationship Assessment Scale, Five Facets of Mindfulness Questionnaire, a treatment expectation questionnaire) at 3 time points (prior to treatment, immediately after treatment, and 6 months after treatment). 5 men (Mage = 44.4, SD = 15.76, Range = 30-67) participated in qualitative exit interviews. MAIN OUTCOME MEASURE: Findings support the feasibility of adapting a mindfulness-based group treatment for situational ED. RESULTS: With respect to feasibility, the dropout rate was 10%, with 1 participant who did not complete the treatment. Comparisons between Time 1 and Time 3 self-reports suggested that this treatment protocol holds promise as a novel means of impacting erectile functioning (Cohen's d = 0.63), overall sexual satisfaction (Cohen's d = 1.02), and non-judgmental observation of one's experience (Cohen's d = 0.52). Participants' expectations for the treatment were generally positive and correlated to self-reported outcomes (r = .68-.73). Qualitative analyses revealed 6 themes: normalization, group magic, identification of effective treatment targets, increased self-efficacy, relationship factors, and treatment barriers. CLINICAL IMPLICATIONS: In a shift toward a biopsychosocial framework for the treatment of men's sexual dysfunction, clinicians may consider incorporating mindfulness to address psychosocial and psychosexual components of dysfunction. STRENGTH & LIMITATIONS: This is the first study-to our knowledge-to adapt mindfulness protocols for use with men's sexual dysfunction. Because this is a pilot study aimed at feasibility, the sample size is small and no control group was included, thus conclusions about efficacy and generalizability cannot be made. CONCLUSION: The current study suggests that a mindfulness group therapy framework offers a feasible and potentially promising treatment avenue for men with situational ED.

PMID- 30297093 TI - Best Practices in North American Pre-Clinical Medical Education in Sexual History Taking: Consensus From the Summits in Medical Education in Sexual Health. AB - INTRODUCTION: This article discusses a blueprint for a sexual health communication curriculum to facilitate undergraduate medical student acquisition of sexual history taking skills and includes recommendations for important elements of a thorough sexual history script for undergraduate medical students. AIM: To outline the fundamentals, objectives, content, timing, and teaching methods of a gold standard curriculum in sexual health communication. METHODS: Consensus expert opinion was documented at the 2012, 2014, and 2016 Summits in Medical Education in Sexual Health. Additionally, the existing literature was reviewed regarding undergraduate medical education in sexual health. MAIN OUTCOME MEASURES: This article reports expert opinion and a review of the literature on the development of a sexual history taking curriculum. RESULTS: First-year curricula should be focused on acquiring satisfactory basic sexual history taking skills, including both assessment of sexual risk via the 5 Ps (partners, practices, protection from sexually transmitted infections, past history of sexually transmitted infections, and prevention of pregnancy) as well as assessment of sexual wellness-described here as a sixth P (plus), which encompasses the assessment of trauma, violence, sexual satisfaction, sexual health concerns/problems, and support for gender identity and sexual orientation. Second-year curricula should be focused on incorporating improved clinical reasoning, emphasizing sexual history taking for diverse populations and practices, and including the impact of illness on sexual health. Teaching methods must include varied formats. Evaluation may be best as a formative objective structured clinical examination in the first year and summative in the second year. Barriers for curriculum development may be reduced by identifying faculty champions of sexual health/medicine. CLINICAL IMPLICATIONS: Medical students will improve their skills in sexual history taking, which will ultimately impact patient satisfaction and clinical outcomes. Future research is needed to validate this proposed curriculum and assess the impact on clinical skills. STRENGTHS & LIMITATIONS: This article assimilates expert consensus and existing clinical guidelines to provide a novel structured approach to curriculum development in sexual health interviewing in the pre-clinical years. CONCLUSION: The blueprint for developing sexual history taking skills includes a spiral curriculum with varied teaching formats, incorporation of a sexual history script that incorporates inquiry about sexual wellness, and longitudinal assessment across the pre-clinical years. Ideally, sexual health communication content should be incorporated into existing clinical interviewing and physical examination courses. Rubin ES, Rullo J, Tsai P, et al.

PMID- 30297095 TI - Higher notch expression implies poor survival in pancreatic ductal adenocarcinoma: A systematic review and meta-analysis. AB - BACKGROUND: At present, pancreatic ductal adenocarcinoma (PDAC) is a fetal disease lack of effective prognostic and therapeutic methods resulting in high mortality. The Notch signaling has been demonstrated being up- or down-regulated in many cancers, but the effects in pancreatic ductal adenocarcinoma are still controversial. Moreover, the available cases in an individual study are of small samples. Therefore, it is essential to define the effect of Notch signaling in pancreatic ductal adenocarcinoma with larger samples. METHODS: Conducted from 6 eligible studies and 463 pancreatic ductal adenocarcinoma patients, this was the first meta-analysis to analyze the correlation between the Notch signal pathway and pancreatic ductal adenocarcinoma. All data were sourced from The National Center for Biotechnology Information, Web of Science and Cochrane. The articles which matched the inclusion criteria were included. All included data were analyzed and performed by Review Manager 5.3. RESULTS: The results indicated that high expression of Notch signaling proteins was associated with poor overall survival of pancreatic ductal adenocarcinoma patients (pooled hazard ratio>2.00; P < 0.001). Moreover, poor survival was related to high expression of Notch3 (pooled hazard ratio: 2.05; confidence interval: 1.49-2.82; P < 0.001) and DLL4 (pooled hazard ratio: 2.13; confidence interval: 1.37-3.32; P < 0.001). CONCLUSIONS: This meta-analysis supports that Notch signaling proteins may be available as prognostic factors for pancreatic ductal adenocarcinoma progression and patient survival. Higher expression of Notch signaling proteins indicated poor survival of pancreatic ductal adenocarcinoma patients. Targeting Notch signaling components, especially Notch3 protein, would be beneficial for therapies. PMID- 30297096 TI - Usefulness of serum biopterin as a predictive biomarker for childhood asthma control: A prospective cohort study. AB - BACKGROUND: Pteridines are metabolites of tetrahydrobiopterin, which serves as co enzyme of nitric oxide synthase. We sought to investigate the usefulness of pteridines as biomarkers for childhood asthma control. METHODS: We conducted a single-center prospective cohort study involving 168 asthmatic children aged 4-17 years who visited the periodical asthma checkup program. Serum neopterin and biopterin levels were measured as pteridines at each visit along with measurement of FeNO, respiratory function tests, nasal eosinophil test, blood eosinophil count, and IgE level. We calculated coefficients for relation between pteridines and asthma control, which was assessed by questionnaires (JPAC: Japanese Pediatric Asthma Control Program). RESULTS: A total of 168 participants aged 10.3 +/- 3.39 years (mean +/- SD) with asthma were recruited. The participants in this study contained 58 patients (34.5%) of complete-controlled based on JPAC, 132 patients (76.0%) of well-controlled group based on GINA. FeNO and serum neopterin level did not correlate with following period's JPAC scores. In contrast, serum biopterin level significantly correlated with following period's JPAC total score (Coefficients 0.398; 95% CI 0.164 to 0.632; p value 0.001) and frequency of wheezing during exercise (Coefficients 0.272; 95% CI 0.217 to 0.328; p value < 0.001). CONCLUSIONS: We found serum biopterin effected the following period's control status of asthmatic children, thus monitoring biopterin level will be a useful for management of asthma to adjust treatment. PMID- 30297097 TI - Challenges of imaging injured Paralympic Athletes. AB - The pattern and mechanism of sports injuries in disabled athletes and the challenges to overcome such injuries is well documented. However, there is limited information regarding the specifics of medical imaging of the injured disabled athletes. This article, reflects on the experience gained during the organisation and provision of the imaging services for the London 2012 Paralympic games. The knowledge gained during these games, in conjunction with information from the existing literature on sporting injuries in disabled athletes can help planning and delivery of well-coordinated imaging services at major disability sporting events. PMID- 30297098 TI - [What is the role of the comprehensive geriatric assessment in Geriatric Oncology?] AB - The growing increase in world population and generalised aging have been accompanied by an increase in the prevalence of cancer in the elderly. Aging is associated with certain physiological changes, some of which are enhanced by the neoplasm itself. Along with this, the elderly oncology patient usually has more problems than the rest of the elderly, and has a multitude of deficits. These characteristics require a special handling of the older patient with cancer, by using the main tool used in Geriatrics, the comprehensive geriatric assessment. This article analyses the importance of the comprehensive geriatric assessment in this population group, paying special attention to its ability to predict the toxicity of chemotherapy and the survival of the elderly oncology, as well as its ability to classify these patients into groups that help in the decision making process. PMID- 30297099 TI - Electroencephalogram findings in patients with posterior cortical atrophy. AB - AIM OF THE STUDY: The aim of this study is to evaluate standard scalp EEG findings in patients with posterior cortical atrophy (PCA), an atypical variant of Alzheimer's disease (AD). CLINICAL RATIONALE: PCA is a topographically selective variant of AD. Patients with typical AD have an increased likelihood of seizures, which may negatively impact overall functional performance and cognition. It is currently unknown what the typical EEG findings are for patients with PCA. MATERIALS AND METHODS: A retrospective chart review was performed on patients identified either with autopsy confirmed (n=13) or clinically (n=126) as PCA. RESULTS: 139 patients were included though only 23 (16.5%) had undergone EEG recording. The EEG was normal in 6 (26%), while an abnormal EEG was present in 17 (74%). Interictal epileptic discharges (IEDs) were found in 2 of the 23 patients (9%). CONCLUSIONS: This study of limited sample size suggests that there may be an increased predilection to find IEDs within PCA when compared to typical AD. Larger cohorts are required to determine frequency of abnormal EEGs in PCA, roles of AEDs in therapy, and in the selection of preferred AED. CLINICAL IMPLICATIONS: Patients with PCA would potentially benefit from an EEG for assessment of IEDs which may provide the clinician with a therapeutic opportunity. PMID- 30297100 TI - Characteristics and clinical correlates of white matter changes in brain magnetic resonance of migraine females. AB - OBJECTIVE: White matter hyperintensities (WMHs) were often found in migraine patients. The aim of study was to characterize WMHs, assess their prevalence, determine relationship to clinical symptoms and homocysteine levels in migraine females. METHODS: 69 women 38 with migraine without aura (MO), 31 with migraine with aura (MA) who underwent brain MRI with 1.5T scanner were enrolled. The WMHs number, location and size in FLAIR sequence were evaluated. Migraine severity was measured by pain intensity, number of attacks per month and MIDAS scale. RESULTS: WMHs were found in 39.1% females. There was no WMHs and migraine type correlation. The total WMHs number was higher in MO (p=0.027). Patients with WMHs were older (p=0.025), have higher BMI (p=0.042), suffered longer (p=0.001), more often had positive pregnancy history (p=0.010) and less frequent prodromal symptoms. The age of onset, migraine's severity and homocysteine did not correlate with WMHs. No effect of antimigraine medication and oral contraceptive pills (OCP) was found. Both in MO and MA groups WMHs were located only supratentorially. In MO females WMHs were mainly located in one cerebral hemisphere (p=0.024) whereas in MA were found bilaterally. WMHs were most commonly located in the frontal lobes. In MO lesions were small <=3mm and present in almost all MO patients (p=0.027). CONCLUSION: WMHs are present in more than one third of migraine females, regardless of aura. WHMs are located supratentorially, subcortically and in the frontal lobes. Older age, longer disease's duration, obesity and positive history of pregnancy are main risk factors for WMHs. Symptomatology and migraine severity, hyperhomocysteinemia, OCP and anti-migraine medications do not increase WMHs. PMID- 30297101 TI - Reduction of Risk Factors for Pedophilic Sexual Offending. AB - INTRODUCTION: Exploratory analysis of characteristics and reduction of risk factors for child sexual abuse (CSA) in a sample treated in the Prevention Projects Dunkelfeld Hannover and Regensburg. AIM: To evaluate a treatment program aimed at reducing dynamic risk factors (DRF) for CSA. METHODS: Using a psychometric test battery based on self-report questionnaires, intergroup analysis between treatment group (TG, n = 35), treatment refusers (TR, n = 51), and drop-out group (DO, n = 14) was conducted with pretreatment data. Intragroup analysis compared data of TG from pre- and posttreatment. The test battery included sociodemographic and sociosexual data, as well as questionnaires measuring DRF. MAIN OUTCOME MEASURE: This study investigated effects of treatment on pedophilic men who are at risk for offending and observed reductions in important risk factors for CSA. RESULTS: TG, TR (consisting of persons who were offered but refused therapy), and DO did not differ regarding sociodemographic and sociosexual variables before therapy. There were no significant differences in education, relationship status, living solitarily, and being a father/stepfather. TR and DO lived farther away from treatment site than TG. In the TG, a reduction in offense-supportive attitudes, coping self-efficacy deficits, and child identification were revealed at second assessment. In TG no participants started the consumption of child abuse content during the course of the study. CLINICAL IMPLICATIONS: Future treatment concepts should focus on the reduction of empirically relevant risk factors for child sexual offending. STRENGTH & LIMITATIONS: The present article is the first that compares TG to TR and DO before assessment regarding DRF and sociosexual variables. Moreover, it is only the second study that investigated treatment effects on a population of pedophilic men who are at risk for offending. These preliminary findings are limited by moderate group size and a missing control group. CONCLUSION: A reduction in some but not all assessed risk factors for sexual offending against minors could be seen within the time frame of therapy. Findings are in line with results from a previous evaluation study. Engel J, Korner M, Schuhman P. Reduction of risk factors for pedophilic sexual offending. J Sex Med 2018;15:1629 1637. PMID- 30297102 TI - Effectiveness of Recurrence Quantification Measures in Discriminating Subjects With and Without Voice Disorders. AB - The objective of this study was to analyze the accuracy of recurrence quantification measurements (RQMs) in discriminating between individuals with and without voice disorders. This study consisted of a total of 541 recorded voice samples from normal and dysphonic subjects. All subjects recorded a sustained vowel /E/ and underwent a laryngoscopic examination of the larynx. Twelve RQMs and three parameters related to the topology of the phonatory system were extracted from the samples, for a total of 15 measures. The classification used quadratic discriminant analysis and includes the measures of accuracy, sensitivity, and specificity. Single measurements such as Shannon's entropy, average diagonal length, and transitivity had only acceptable performance ratings (>=70%) in discriminating between individuals with and without voice disorders. The combination of the parameters average diagonal length, Shannon's entropy, trapping time, length of the longest vertical line, tau, imbedding dimension, neighborhood radius, and transitivity produced the highest accuracy in discrimination (83.27%). Therefore, the performance of RQMs related to the formation of diagonal lines in classifying individuals with and without voice disorders was acceptable at >=70%. A combination of RQMs showed good performance in discriminating between the study groups, with higher sensitivity and specificity. PMID- 30297103 TI - Maturation and fertilization of echinoderm eggs: Role of actin cytoskeleton dynamics. AB - Starfish and sea urchin are excellent models to study the mechanisms that regulate oocyte maturation and egg activation. Hormonal stimulation of starfish oocytes and their following interaction with spermatozoa induce rapid changes of F-actin and Ca2+ increases which are prerequisites for normal fertilization and development. Fully grown oocytes isolated from the gonads of starfish contain a large nucleus (~60-70 MUm) (termed germinal vesicle, GV), which is arrested at the first prophase of meiosis. If inseminated, these immature oocytes are penetrated by additional spermatozoa. However, starfish oocytes naturally shed into the sea have already initiated the (meiotic) maturation and are normally fertilized between GV breakdown and the extrusion of the first polar body. This is considered the optimum period to ensure monospermic instead of polyspermic fertilization. By contrast, sea urchin eggs are fertilized only after being fully matured, i.e., at the end of the two meiotic divisions. Here, we provide a comparative review of the role of the actin cytoskeleton in oocyte maturation and fertilization in starfish and sea urchin. It has become increasingly evident that the exquisite regulation of the cortical F-actin is involved in nearly all aspects of the molecular events taking place during the progression of meiotic maturation and fertilization. PMID- 30297104 TI - LINC00662 promotes gastric cancer cell growth by modulating the Hippo-YAP1 pathway. AB - Long non-coding RNAs (lncRNAs) function as vital regulators of the progression of various diseases, particularly cancers. In the present study, utilizing the Cancer Genome Atlas (TCGA) data set and a series of cell experiments and clinical tissue samples assays, we found that LINC00662 expression was significantly up regulated in gastric cancer (GC) tissues and cell lines. High expression of LINC00662 predicted poor prognosis compared to in patients showing low expression. Knockdown of LINC00662 expression decreased GC cell proliferation and increased the chemo-sensitivity of GC cells. Further, we demonstrated that knockdown of LINC00662 suppressed the Hippo-YAP1 signaling pathway in GC cells. Mechanistically, LINC00662 regulated YAP1-mediated GC cell proliferation by sponging miR-497-5p. Overall, our results revealed a critical role for the LINC00662-miR-497-5p-YAP1 axis in GC cell growth, providing a new target for GC. PMID- 30297105 TI - Cyclophilin 1 (Cyp1) mutation ameliorates oxidative stress-induced defects in a Drosophila DJ-1 null mutant. AB - Drosophila cyclophilin 1 (Cyp1) is a structural and functional homolog of mammalian cyclophilin D (CypD), a unique mitochondrial cyclophilin (Cyp) that regulates the inner mitochondrial membrane permeability transition and cell survival under cellular stresses such as oxidative damage. In this study, we generated and characterized a Drosophila Cyp1 mutant. Cyp1 mutant flies successfully developed into adults and showed no significant defects in mitochondrial morphology, function, and content. However, oxidative damage significantly decreased in Cyp1 mutant flies, and inhibition of Cyp1 expression substantially increased the survival under various oxidative stress paradigms. Moreover, Cyp1 mutation successfully ameliorated survival rates, locomotor activity, and dopaminergic neuron quantity in a Drosophila DJ-1 mutant under oxidative stress, further confirming the protective role of Cyp1 mutation against oxidative stress. In conclusion, these results suggest Cyp1 and its human homolog CypD as putative molecular targets for the treatment of DJ-1 deficiency associated diseases, including Parkinson's disease. PMID- 30297106 TI - Gene expression profiling in adipose tissue of Sprague Dawley rats identifies olfactory receptor 984 as a potential obesity treatment target. AB - The aim of the study was to identify and functionally characterize novel candidate gene/s involved in the development of resistance to diet-induced obesity in rats. In a high-fat-diet (HFD) study of rats, we found subgroups which either developed resistance to HFD-induced obesity (DR) or showed an obesity prone phenotype (DIO). Gene expression analysis in 10 samples (5 DIO vs 5 DR) was performed. The most promising gene, OR6C3 (orthologous with rat Olr984 and mouse Olfr788) was measured by qRT-PCR in paired samples of human visceral (Vis) and subcutaneous (SC) adipose tissue (AT) (n = 225) and in sub-fractions of adipocytes and cells of stromal vascular fraction. Gene expression analyses showed Olr984 with significantly reduced mRNA expression in DR rats. In the Vis AT of human samples we found an up-regulation of OR6C3 compared to SC AT, independent of gender, glucose tolerance or type 2 diabetes. We observed significantly lower levels of SC AT OR6C3 mRNA in subjects with obesity compared to those with normal-weight or overweight. OR6C3 is more expressed in SVF than in adipocytes. Olr984 could be a novel candidate gene related to diet-induced obesity in rats. Variation in human AT mRNA expression is related to obesity parameters and glucose homeostasis and linked to the regulatory role of insulin on the Olr984. PMID- 30297107 TI - The long noncoding RNA XIST protects cardiomyocyte hypertrophy by targeting miR 330-3p. AB - Long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) are implicated in numerous kinds of cardiovascular diseases, and their vital role in regulating cardiac hypertrophy still needs to be explored. In this study, we demonstrated that lncRNA X-inactive specific transcript (XIST) was upregulated in hypertrophic cardiac of mice and phenylephrine (PE)-treated cardiomyocytes. Next, we observed that inhibition of XIST induced hypertrophic response of cardiomyocyte and overexpression of XIST attenuated cardiomyocyte hypertrophy induced by PE. Furthermore, through online predictive tools and functional experiments, we demonstrated that XIST and S100B were targets of miR-330-3p. XIST and miR-330-3p suppressed each other in a reciprocal way in cardiomyocytes. Additionally, XIST promoted S100B expression through harboring the complementary binding sites with miR-330-3p, eventually prevented cardiac hypertrophy. In conclusion, our findings revealed a novel molecular mechanism that XIST/miR-330-3p/S100B pathway modulates the progression of cardiomyocyte hypertrophy. PMID- 30297108 TI - A novel derivative (GTN024) from a natural product, komaroviquinone, induced the apoptosis of high-risk myeloma cells via reactive oxygen production and ER stress. AB - New drugs have significantly improved the survival of patients with multiple myeloma (MM), but the prognosis of MM patients with high-risk cytogenetic changes such as t(4; 14), t(14; 16) or del17p remains very poor. A natural product, komaroviquinone (KQN), was originally isolated from the perennial semi-shrub Dracocephalum komarovi and has anti-protozoal activity against Trypanosoma cruzi, the organism causing Chagas' disease. Here we demonstrate that a novel KQN derivative, GTN024, has an anti-MM effect both in vitro and in vivo. GTN024 induced the apoptosis of MM cell lines including those with high-risk cytogenetic changes. GTN024 produced reactive oxygen species (ROS) and increased phosphorylated eIF2alpha. The ROS production and subsequent endoplasmic reticulum (ER) stress are thought to play a key role in GTN024-induced apoptosis, as the apoptosis was completely abrogated by anti-oxidant treatment. In a mouse xenograft model, an intraperitoneal injection of 20 mg/kg of GTN024 significantly delayed tumor growth. Hematological toxicity and systemic toxicity as indicated by weight loss were not observed. These results suggest that the novel KQN derivative GTN024 could become a candidate drug for treating high-risk MM.

AB - Unlike stable and immobile cell line conditions, animal hearts contract and relax to pump blood throughout the body. Mitochondria play an essential role by producing biological energy molecules to maintain heart function. In this study, we assessed the effect of heart mimetic cyclic stretch on mitochondria in a cardiac cell line. To mimic the geometric and biomechanical conditions surrounding cells in vivo, cyclic stretching was performed on HL-1 murine cardiomyocytes seeded onto an elastic micropatterned substrate (10% elongation, 0.5 Hz, 4 h/day). Cell viability, semi-quantitative Q-PCR, and western blot analyses were performed in non-stimulated control and cyclic stretch stimulated HL-1 cell lines. Cyclic stretch significantly increased the expression of mitochondria biogenesis-related genes (TUFM, TFAM, ERRalpha, and PGC1-alpha) and mitochondria oxidative phosphorylation-related genes (PHB1 and CYTB). Western blot analysis confirmed that cyclic stretch increased protein levels of mitochondria biogenesis-related proteins (TFAM, and ERRalpha) and oxidative phosphorylation-related proteins (NDUFS1, UQCRC, and PHB1). Consequently, cyclic stretch increased mitochondrial mass and ATP production in treated cells. Our results suggest that cyclic stretch transcriptionally enhanced mitochondria biogenesis and oxidative phosphorylation without detrimental effects in a cultured cardiac cell line. PMID- 30297110 TI - Vascular apoptosis associated with meglumine antimoniate: In vivo investigation of a chick embryo model. AB - The vasculo-toxic effect of meglumine antimoniate (MA) was confirmed in our previous investigation. The current study investigates the association of this effect with altered VEGF-A and VEGF-R2 expression. Additional mechanisms by which MA causes vascular toxicity are not clearly understood. We hypothesized that MA may alter normal expression of apoptotic genes and cause vascular toxicity. The current investigation was designed to address this issue using a chick embryo model. Fertile chicken eggs were treated with MA and the extra-embryonic membrane (EEM) vasculature was evaluated by morphometric, molecular and immunohistochemistry assays. The results showed that MA not only altered apoptotic gene expression, but that this alteration may disturb the normal development of the vascular network and cause embryo malformation. The relative expression level of the CASP3, CASP7, CASP9, APAF1, AIF1 and TP53 genes increased in drug-exposed EEMs. In addition, IHC assay confirmed the low expression BCL2 and increased expression of Bax, which are associated with a high rate of apoptosis. We suggest that induction of an apoptotic signaling pathway can lead to vascular defects during embryo development and the consecutive cascade of events can lead to the embryo malformation. PMID- 30297111 TI - Wucherria bancrofti glutathione S-Transferase: Insights into the 2.3 A resolution X-ray structure and function, a therapeutic target for human lymphatic filariasis. AB - The notoriety of parasitic nematode survival is directly related to chronic pathogenicity, which is evident in human lymphatic filariasis. It is a disease of poverty which causes severe disability affecting more than 120 million people worldwide. These nematodes down-regulate host immune system through a myriad of strategies that includes secretion of antioxidant and detoxification enzymes like glutathione-S-transferases (GSTs). Earlier studies have shown Wuchereria bancrofti GST to be a potential therapeutic target. Parasite GSTs catalyse the conjugation of glutathione to xenobiotic and other endogenous electrophiles and are essential for their long-term survival in lymph tissues. Hence, the crystal structure of WbGST along with its cofactor GSH at 2.3 A resolution was determined. Structural comparisons against host GST reveal distinct differences in the substrate binding sites. The parasite xenobiotic binding site is more substrate/solvent accessible. The structure also suggests the presence of putative non-catalytic binding sites that may permit sequestration of endogenous and exogenous ligands. The structure of WbGST also provides a case for the role of the pi-cation interaction in stabilizing catalytic Tyr compared to stabilization interactions described for other GSTs. Hence, the obtained information regarding crucial differences in the active sites will support future design of parasite specific inhibitors. Further, the study also evaluates the inhibition of WbGST and its variants by antifilarial diethylcarbamazine through kinetic assays. PMID- 30297112 TI - As an independent prognostic factor, USP6 promotes the invasion and metastasis of colon cancer. AB - The lack of efficient tumor invasion and metastatic biomarkers led to high mortality rates in colon cancer patients. Aberrant expression of ubiquitin specific protease 6 (USP6) was involved in several diseases including cancer, while its role in the progression of colon cancer was still unclear. In this study, USP6 was evaluated at both mRNA and protein levels by using RT-PCR, western blot and immunohistochemistry staining analyses. The results revealed that high USP6 expression predicted poor disease-specific survival and overall survival through Kaplan-Meier analyses with log-rank tests, univariate and multivariate Cox analyses. Furthermore, cell function assay demonstrated that USP6 could promote colon cancer cells' invasion in vitro and liver metastasis in vivo. These findings indicated that high USP6 expression contributed to the progression of colon cancer and USP6 may be a valuable prognostic factor in patients with colon cancer. PMID- 30297113 TI - The expected cumulative incidence of live birth of patients starting IVF treatment at age 41 years or older. AB - RESEARCH QUESTION: What is the cumulative incidence of live birth (CLIB) for high order consecutive IVF cycles, and which factors are associated with live birth of women aged >=41 years using autologous oocytes? DESIGN: A retrospective cohort study including 146 patients aged 41 years to <44 years who started their first IVF cycle attempt using autologous oocytes, between January 2006 and December 2013. RESULTS: After 13 IVF cycles, CILB reached up to 33.6%. After six IVF cycles, 42 (28.8%) women delivered a live infant (85.7% of the total live birth). Mean live birth rate per cycle declined with age at the initial cycle (8% at 41 years; 5.8% at 42 years; and 4.1% at 43 years). Multivariable modified Poisson regression models identified patient's age (RR for 41 years versus 43 years: 0.47; 95% CI 0.25 to 0.87; P = 0.01), smoking status (RR 0.21; 95% CI 0.05 to 0.08; P = 0.02), and mean number of fertilized oocytes (RR 1.23; 95% CI 1.08 to 1.39; P < 0.01) as factors significantly associated with the probability of a live birth. CONCLUSIONS: Multiple repeat IVF cycles in women aged 41-44 years offers a reasonable long-term success rate. After six cycles of treatment, about 29% of women of advanced reproductive age using autologous oocytes expected to achieve a live birth. This information might assist in fertility counselling and managing patients' expectations by adjusting the appropriate treatment strategy and number of IVF cycle attempts, especially in countries in which egg donation is prohibited or when multiple repeated IVF cycles attempts are financially affordable. PMID- 30297114 TI - Distinctive expression profiles of Caveolin-1 and Notch-1 protein in patients with nasal polyps or sinonasal inverted papillomas. AB - BACKGROUND: Nasal polyposis (NP) and sinonasal inverted papillomas (SIP) are considered benign lesions capable of recurrence or malignant transformation although not with the same prevalence. Since fluctuations of Caveolin-1 and Notch 1 proteins expression have been reported in many pathologies, the current study aimed to investigate their involvement in the epithelial transformation observed in SIPs compared to NP. METHODS: Immunohistochemical expression of Caveolin-1 and Notch-1 proteins was assessed in 104 patients with sinonasal lesions (45 NP, 45 SIP and 14 NP with SIP), semiquantively (percentage times intensity). Proteins expression profiles were evaluated statistically for their correlation with patients demographic and clinicopathological variables (grade of dysplasia, inflammation, recurrence) as well as with markers of proliferation (Ki67) and apoptosis (7-AAD) as determined by flow cytometry analysis. RESULTS: SIP lesions presented increased Caveolin-1 immunopositivity compared to NP (62.2%, vs 40.9%; p = 0.045). Cytoplasmic staining was observed only in epithelium's basal and suprabasal layers. Caveolin-1 positivity was not related to Ki67 expression, apoptosis, inflammation or dysplasia, eventhough 81.8% of highly immunopositive lesions were dysplastic (p = 0.03). Also, smokers presented significantly increased immunopositivy (p = 0.03). In contrast SIP lesions presented reduced Notch-1 expression compared to NP (68.9% vs 100%; p < 0.001). Dysplastic lesions presented low Notch-1 immunopositivity (p < 0.001). Enhancement of Notch-1 gene expression was also associated with inflammation. CONCLUSIONS: The herein presented data suggest that the expression profiles of Caveolin-1 and Notch-1 proteins in sinonasal pathologies are distinctive and that could be explored as potential targets for the development of alternative therapeutic approaches. PMID- 30297115 TI - Are dual mobility cups associated with increased metal ions in the blood? Clinical study of nickel and chromium levels with 29 months' follow-up. AB - INTRODUCTION: Dual mobility cups have become the implant of choice for older patients with a high risk of dislocation. However, to our knowledge, no study has explored the possibility of metal ion production with these implants that incorporate a polyethylene-on-metal bearing. This led us to conduct a prospective study to determine whether use of a dual mobility cup is accompanied by increased levels of nickel and chromium in the blood. HYPOTHESIS: Use of a dual mobility cup is accompanied by an increase of nickel and chromium levels in the blood. METHODS: Between 2012 and 2015, 16 consecutive patients were enrolled in the study. They underwent primary hip arthroplasty with a ceramic BioloxTM head (CeramTec, Plochingen, Germany), CorailTM titanium alloy stem (DePuy Synthes, Saint Priest, France) and a NovaeTM dual mobility cup (SERF, Decines-Charpieu, France) consisting of 19% chromium (Cr) and 13-15% nickel (Ni). Patients who had other potential sources of nickel or chromium in their body (joint implants, dental implants, etc.) were excluded. The blood levels (MUg/L) of nickel and chromium were measured preoperatively and at 2 years' follow-up by an independent laboratory (Biomnis) using inductively coupled plasma mass spectrometry. The upper limits set by the laboratory were<0.87MUg/L for chromium and<1.0MUg/L for nickel. AP and lateral X-rays of the pelvis were taken preoperatively and at each postoperative follow-up visit to look for signs of loosening. The Postel-Merle d'Aubigne (PMA) score was determined preoperatively and at each postoperative follow-up visit. Surgical revision procedures for any cause were also documented. RESULTS: The mean follow-up was 29 months [13-39]. Preoperatively, blood nickel ion levels were measured in 7 patients; they were below 1MUg/L in 6 patients (86%) and at 1.5MUg/L in 1 patient (14%). The mean preoperative chromium ion levels (n=7) was 0.2MUg/L [0-0.8MUg/L]. Postoperatively, all 16 enrolled patients had their blood ion levels checked at a mean follow-up of 29 months. The nickel ion levels averaged 1.69+/-1.49 [0.2-5.6] (with 4/16 having>2MUg/L and 12/16>1MUg/L) and the chromium ion levels averaged 0.5+/-0.11 [0.4-0.7] (with no patients>0.7MUg/L). There were no signs of loosening or osteolysis on the follow up radiographs. The mean PMA score at 2 years was 17.8 [17,18]. CONCLUSION: We found that dual mobility cups generate increased nickel but not chromium ions in the blood. The levels measured are comparable to those for other orthopedic implants such as spine implants. The clinical consequences of these increased levels are not known. Nevertheless, there were no clinical or radiological signs of loosening, although the follow-up was only 2 years. LEVEL OF EVIDENCE: IV, Cohort study.

AB - Acquired urethrovaginal fistulae and urethral atresia are rare findings in pediatric patients, but have been described in adult patients related to trauma or iatrogenic injury. Little exists in the published literature to guide management of such conditions in children, but lessons learned from congenital causes can help. Herein we discuss the preoperative evaluation and management of a child with an acquired urethrovaginal fistula and urethral atresia likely related to in utero compression from an intrapelvic sacrococcygeal teratoma and provide several images detailing the complex anatomy. PMID- 30297117 TI - .Clostridioides difficile. AB - Clostridioides difficile is a spore-forming, anaerobic, intestinal pathogen that causes severe diarrhea that can lead to death. In 2011, C. difficile infected ~500000 people in the USA and killed ~29000 people. C. difficile infection (CDI) is the most common healthcare-related infection in the USA, leading to increased healthcare costs of $4.8 billion. This pathogen transmits via the oral-fecal route as a highly contagious and resilient spore. Upon exposure to primary bile acids in the intestine, C. difficile germinates, and in the absence of colonization resistance from the normal microbiota, the bacterium colonizes the colon and produces toxins. These toxins inhibit actin polymerization in host cells, leading to cell death. C. difficile cells can then sporulate in the intestine and exit the body via diarrheal shedding. In culture, sporulation is induced at stationary phase in a nutrient-limiting environment, but the intestinal triggers of sporulation are still unknown. PMID- 30297118 TI - Sterically induced conformational restriction: Discovery and preclinical evaluation of novel pyrrolo[3,2-d]pyrimidines as microtubule targeting agents. AB - The discovery, synthesis and biological evaluations of a series of nine N5 substituted-pyrrolo[3,2-d]pyrimidin-4-amines are reported. Novel compounds with microtubule depolymerizing activity were identified. Some of these compounds also circumvent clinically relevant drug resistance mechanisms (expression of P glycoprotein and betaIII tubulin). Compounds 4, 5, and 8-13 were one to two-digit nanomolar (IC50) inhibitors of cancer cells in culture. Contrary to recent reports (Banerjee et al. J. Med. Chem.2018, 61, 1704-1718), the conformation of the most active compounds determined by 1H NMR and molecular modeling are similar to that reported previously and in keeping with recently reported X-ray crystal structures. Compound 11, freely water soluble as the HCl salt, afforded statistically significant inhibition of tumor growth in three xenograft models [MDA-MB-435, MDA-MB-231 and NCI/ADR-RES] compared with controls. Compound 11 did not display indications of animal toxicity and is currently slated for further preclinical development. PMID- 30297120 TI - Chemistry-driven glycoscience. AB - Carbohydrates are the most prominent features of the cell's exterior-they are the cell's "face" and serve as the cell's identification card. The features of cell surface glycans (e.g. glycoproteins, glycolipids, polysaccharides) can be read by proteins, other cells, or organisms. In all of these contexts, glycan-binding proteins typically recognize ("read") glycan identity. This recognition mediates important host-microbe interactions, as well as critical physiological functions, including fertilization, development, and immune system function. This article focuses on how proteins recognize glycans with an emphasis on three objectives: 1) to understand the molecular basis for carbohydrate recognition, 2) to implement that understanding to develop functional probes of protein-carbohydrate interactions, and 3) to apply those probes to elucidate and exploit the physiological consequences of protein-carbohydrate interactions. In this context, our group has focused on two key aspects of carbohydrate recognition: CH-pi and multivalent interactions. We are applying the foundational knowledge gained from our studies for purposes ranging from illuminating host-microbe interactions to probing immune system function. PMID- 30297119 TI - Discovery and biological evaluation of thiobarbituric derivatives as potent p300/CBP inhibitors. AB - Histone acetyltransferases (HATs) relieve transcriptional repression by preferentially acetylation of epsilon-amino group of lysine residues on histones. Dysregulation of HATs is strongly correlated with etiology of several diseases especially cancer, thus highlighting the utmost significance of the development of small molecule inhibitors against this potential therapeutic target. In the present study, through virtual screening and iterative optimization, we identified DCH36_06 as a bona fide, potent p300/CBP inhibitor. DCH36_06 mediated p300/CBP inhibition leading to hypoacetylation on H3K18 in leukemic cells. The suppression of p300/CBP activity retarded cell proliferation in several leukemic cell lines. In addition, DCH36_06 arrested cell cycle at G1 phase and induced apoptosis via activation of capase3, caspase9 and PARP that elucidated the molecular mechanism of its anti-proliferation activity. In transcriptome analysis, DCH36_06 altered downstream gene expression and apoptotic pathways related genes verified by real-time PCR. Importantly, DCH36_06 blocked the leukemic xenograft growth in mice supporting its potential for in vivo use that underlies the therapeutic potential for p300/CBP inhibitors in clinical translation. Taken together, our findings suggest that DCH36_06 may serve as a qualified chemical tool to decode the acetylome code and open up new opportunities for clinical intervention.

PMID- 30297122 TI - Impact of maternally derived pertussis antibody titers on infant whole-cell pertussis vaccine response in a low income setting. AB - BACKGROUND: Maternal vaccines against pertussis are not yet recommended in the developing world. Besides unclear burden estimates, another concern is that transplacental transfer of maternal pertussis antibodies could result in attenuation of the immune response to whole cell pertussis (DTwP) primary vaccination series in infants. This study was taken up to determine whether higher levels of maternal pertussis antibodies attenuate immune response of infants to DTwP vaccination series given at 6-10-14 weeks of age. METHODOLOGY: A total of 261 pregnant women and their infants from four low-income settlements in Karachi, Pakistan were enrolled in this study. The study endpoints were infant antibody titers for Pertussis toxin (PTx), Filamentous hemagglutinin antigen (FHA), Pertactin (PRN) and Fimbriae type 2/3 (FIM) - from birth through 18 weeks of age. Cord blood or pre-vaccine pertussis antibody titers indicate the concentration of maternal antibodies transferred to infants. Linear regression models were used to determine the association between higher maternal antibody titers and infant immune response to DTwP vaccine. Geometric Mean Ratio (GMR) was calculated as the ratio of infant antibody titers at specified time points against the maternal antibody titers at the time of delivery. RESULTS: At eighteen weeks of age, the adjusted beta regression coefficient for PTx was 0.06 (95% CI: -0.49-0.61), FHA 0.02 (95% CI: -0.26 -0.29), PRN 0.02 (95%CI -0.38- 0.43), and FIM 0.17 (95%CI: -0.21-0.54). Among infants who received at least two doses of DTwP vaccine, higher maternal antibody titers did not have any attenuating effect on infant post-immunization antibody titers against all four pertussis antigens. CONCLUSION: Maternal pertussis antibodies did not attenuate infant's immune response to pertussis antigens in DTwP primary vaccine given at 6 10-14 weeks of age. PMID- 30297123 TI - The roles of neighborhood composition and autism prevalence on vaccination exemption pockets: A population-wide study. AB - The number of children entering schools without mandated vaccinations has increased in high-income countries due to the rise of nonmedical exemptions from school vaccination requirements. Herd immunity is threatened when unvaccinated children are concentrated in spatial pockets. Despite the role of vaccine-autism controversy in the current wave of the anti-vaccine movement, we do not know if exemption clusters are associated with local autism rates; it is often assumed that these clusters are merely the result of sociodemographic composition. This study uses data on the number of students with a Personal Belief Exemption reported by schools from 1992 to 2014 and unique data on the locations of children with an autism diagnosis in California to study the correlates of large exemption pockets. Our spatial analysis shows that the prevalence of autism is not associated with the locations of large pockets of vaccination exemptions. Likewise, the spatial distributions of socioeconomic factors and proximity to health care resources have limited roles in explaining these large exemption pockets. Racial/ethnic composition, however, has strong associations with the locations of the large pockets. Our results suggest that community-level interventions are needed to maintain herd immunity as exemption pockets are not merely the result of population composition.

PMID- 30297124 TI - Quadrivalent HPV vaccine in HIV-1-infected early adolescent girls and boys in Kenya: Month 7 and 12 post vaccine immunogenicity and correlation with immune status. AB - INTRODUCTION: In sub-Saharan Africa, a generation of HIV-1-infected children is approaching the age of sexual debut and becoming at risk for HPV infection and its sequelae. We assessed safety and immunogenicity of the quadrivalent HPV (qHPV) vaccine in HIV-1-infected adolescents. METHODS: In an open-label trial among Kenyan, HIV-1-infected adolescents aged 9-14 years, we administered the qHPV vaccine at 0, 2 and 6 months and measured antibody titers to HPV-16, 18, 6 and 11 at month 7 and 12 post-vaccination. Measures of immunogenic response from HIV-1-negative historical cohorts from Africa and HIV-1 positive adolescent cohorts from the USA were used for comparison. RESULTS: We enrolled 100 girls and 80 boys with a median age of 12 years and median baseline CD4 cell count of 684 (IQR 478, 935) cells/uL. One hundred and fifty four (86%) were receiving antiretroviral therapy for a median of 4.5 (IQR 2.3, 6.3) years; 110 (71%) had <400 copies of plasma HIV-1 RNA/mL. Of 189 enrolled children, 179 received all three doses. Two hundred and eighty five (64%) of 445 adverse events were injection site reactions; none were greater than grade 2. Of 6 Serious Adverse Events (SAEs), none were considered vaccine related. Seroconversion to HPV-18, 16, 11, 6 at month 7 occurred in 93.3%, 98.3%, 97.2% and 99.6% of vaccine recipients; similar rates have been reported in historical controls. The mean log10 HPV antibody titer measured at month 7 increased with each log10 increase in CD4 by 1.4 (95% CI: 1.1-1.7) for HPV-18; 1.2 (0.9-1.4) for HPV-16; 1.1 (0.8 1.3) for HPV-11; 0.7 (0.5-1.0) for HPV-6 (all p < 0.0001). CONCLUSION: Almost all Kenyan HIV-1-infected adolescents mounted an immune response comparable to other immunized populations. HPV antibody titers were higher in those with preserved CD4 cell counts. Longer term-follow up will determine sustainability of the immune response. ClinicalTrials.gov number, NCT00557245. PMID- 30297126 TI - Applicant perceptions of new selection systems are a function of their performance in the selection procedure. AB - INTRODUCTION: Screening practices for selecting surgery trainees have been criticized for subjectivity, inefficiency, and inability to predict performance. This study explored applicant perceptions to an untraditional selection process. METHODS: Fellowship applicants completed an online assessment containing 26 situational judgment test (SJT) items and a 108-item personality profile. High performing candidates participated in on-site structured interviews and skills testing. Upon completion of all interviews, but before match results were available, an anonymous, online survey was sent to all applicants. The survey asked about perceptions of the selection system along dimensions of procedural justice theory on a 1 (strongly disagree) to 5 (strongly agree) scale. RESULTS: Twenty-one of 51 applicants completed the survey. Those invited for an interview (N = 12) had more favorable perceptions about communication (3.50 +/- 1.38 versus 2.00 +/- 0.82,p < 0.05), opportunity to perform (3.33 +/- 1.56 versus 1.29 +/- 0.49,p < 0.01), fairness (4.50 +/- 0.80 versus 3.43 +/- 1.40,p < 0.05) and gaining more insight (4.25 +/- 1.22 versus 2.29 +/- 1.60,p < 0.01) compared to applicants not invited. Content (4.21 +/- 0.86) and consistency (4.79 +/- 0.42) means were similar. CONCLUSIONS: These results suggest that applicant perceptions are directly related to how well they perform in the selection procedure. PMID- 30297127 TI - Association of endogenous sex hormone levels with coronary artery calcium progression among post-menopausal women in the Multi-Ethnic Study of Atherosclerosis (MESA). AB - BACKGROUND: Sex differences in the incidence and manifestation of cardiovascular disease (CVD) suggest the involvement of sex hormones in disease pathogenesis. Coronary artery calcium (CAC) and its progression, measured by non-contrast cardiac computed tomography, are markers of subclinical atherosclerosis and predict CVD, even among low-risk women. We hypothesized that sex hormone levels were associated with CAC progression among women in the Multi-Ethnic Study of Atherosclerosis. METHODS: We studied 2759 post-menopausal women (age 65 +/- 9 years), free of baseline CVD, with baseline serum sex hormones and CAC measured at Exam 1 (2000-2002). Of this sample, 2427 had >=1 follow-up CAC measurement through Exam 5 (2010-2012). Using mixed effects linear regression methods, we tested change in log[CAC+1] score by log[sex hormone] levels (continuous, comparing the 90th versus 10th percentiles). Models adjusted for demographics, lifestyle factors, cardiovascular risk factors, hormone therapy, and years since menopause. RESULTS: At baseline, we found no associations between sex hormones and prevalent CAC. Over a median of 4.7 years, in fully-adjusted models, women with higher free testosterone levels had relatively greater CAC progression [Ratio 1.26 (95% CI 1.01-1.56)], whereas higher sex hormone binding globulin (SHBG) was associated with lower progression risk [0.80 (0.64-0.99). No associations were seen for total testosterone, estradiol, or dehydroepiandrosterone. CONCLUSION: A more androgenic hormone profile of higher free testosterone and lower SHBG is associated with a greater CAC progression up to 10-years in post-menopausal women. Sex hormone levels may help identify women at increased risk for CVD who may benefit from additional risk-reducing strategies.

PMID- 30297128 TI - Use of coronary artery calcium testing to improve coronary heart disease risk assessment in a lung cancer screening population: The Multi-Ethnic Study of Atherosclerosis (MESA). AB - BACKGROUND: Assessment of coronary artery calcium (CAC) during lung cancer screening chest computed tomography (CT) represents an opportunity to identify asymptomatic individuals at increased coronary heart disease (CHD) risk. We determined the improvement in CHD risk prediction associated with the addition of CAC testing in a population recommended for lung cancer screening. METHODS: We included 484 out of 6814 Multi-Ethnic Study of Atherosclerosis (MESA) participants without baseline cardiovascular disease who met U.S. Preventive Service Task Force CT lung cancer screening criteria and underwent gated CAC testing. 10 year-predicted CHD risks with and without CAC were calculated using a validated MESA-based risk model and categorized into low (<5%), intermediate (5% 10%), and high (>=10%). The net reclassification improvement (NRI) and change in Harrell's C-statistic by adding CAC to the risk model were subsequently determined. RESULTS: Of 484 included participants (mean age = 65; 39% women; 32% black), 72 (15%) experienced CHD events over the course of follow-up (median = 12.5 years). Adding CAC to the MESA CHD risk model resulted in 17% more participants classified into the highest or lowest risk categories and a NRI of 0.26 (p = 0.001). The C-statistic improved from 0.538 to 0.611 (p = 0.01). CONCLUSIONS: CHD event rates were high in this lung cancer screening eligible population. These individuals represent a high-risk population who merit consideration for CHD prevention measures regardless of CAC score. Although overall discrimination remained poor with inclusion of CAC scores, determining whether those reclassified to an even higher risk would benefit from more aggressive preventive measures may be important. PMID- 30297130 TI - Effect of oral trazodone on the minimum alveolar concentration of isoflurane in dogs. AB - OBJECTIVE: To determine the effect of oral trazodone on the minimum alveolar concentration (MAC) of isoflurane in dogs. STUDY DESIGN: Prospective blinded, single-observer, randomized crossover experimental study. ANIMALS: Six adult (age 6.8 +/- 1.6 months) healthy dogs (three males and three females), weighing 24.8 +/- 3.4 kg (mean +/- standard deviation). METHODS: Each dog was anesthetized twice with a minimum of 7 days between anesthetic episodes. Dogs were randomly assigned to be administered two treatments in a crossover design: premedication with trazodone (8 mg kg-1; TRAZ-ISO) orally 2 hours prior to an anesthetic episode or no (ISO). Dogs were anesthetized with intravenous propofol (6 mg kg-1) and isoflurane in >95% oxygen. Isoflurane MAC was determined using an iterative bracketing technique with electrodes placed in the buccal mucosa. Hemodynamic variables were compared at the lowest end-tidal isoflurane concentration at which each dog did not respond. A paired t test was used to assess the effect of treatment on outcome variables with significance set to a value of p < 0.05. RESULTS: The MAC concentration (mean +/- standard deviation) in dogs administered TRAZ-ISO was 0.85 +/- 0.17% compared with 1.02 +/- 0.11% in those administered ISO (p = 0.01, 95% confidence interval -0.25 to -0.05), resulting in a mean MAC reduction of 17 +/- 12%. There were no differences in hemodynamic variables between treatments. CONCLUSIONS AND CLINICAL RELEVANCE: Premedication of dogs with oral trazodone (8 mg kg-1) 2 hours prior to anesthetic induction has a significant isoflurane MAC sparing effect with no significant observed hemodynamic benefit. PMID- 30297131 TI - Colon constipation in horses after sustained-release buprenorphine administration. AB - OBJECTIVE: To investigate the pharmacological profile and side effects of buprenorphine administered as a sustained-release formulation in horses. STUDY DESIGN: Pilot trial. ANIMALS: A total of four experimental horses, aged 18-27 years and weighing 508-578 kg. METHODS: Buprenorphine (0.1 mg kg-1) was mixed as a freshly prepared sterile solution with a sustained-release drug carrier. It was administered by the subcutaneous (n = 2) or intramuscular (n = 2) route. During the experiment, the horses were closely monitored, equipped with a step counter and blood samples were collected for quantification of buprenorphine in plasma. RESULTS: All four horses developed colon constipation requiring medical therapy, together with increased locomotor activity. One horse, requiring surgical treatment of colon constipation, was euthanized during recovery from anaesthesia for weakness and severe lower airway obstruction. The three other horses recovered fully within 5-7 days. Plasma buprenorphine concentrations were between 1 and 8 ng mL-1 for approximately 48 hours. No local reaction was observed at the injection sites. CONCLUSIONS AND CLINICAL RELEVANCE: Administration of the sustained-release formulation of buprenorphine at a dose of 0.1 mg kg-1 resulted in plasma concentrations compatible with antinociceptive activity for at least 48 hours. The observed severe and undesirable effects of colon constipation and increased locomotor activity definitely preclude clinical use of sustained release buprenorphine at this dose.

Plugins are dynamically linked libraries that allow users to add new features and to couple FEBio with other domain-specific software applications without modifying the source code directly. The governing equations and simulation capabilities of FEBio are reviewed. The implementation, structure, use, and application of the plugin framework are detailed. Several example plugins are described in detail to illustrate how plugins enrich, extend, and leverage existing capabilities in FEBio, including applications to deformable image registration, constitutive modeling of biological tissues, coupling to an external software package that simulates angiogenesis using a discrete computational model, and a nonlinear reaction-diffusion solver. The plugin feature facilitates dissemination of new simulation methods, reproduction of published results, and coupling of FEBio with other domain-specific simulation approaches such as compartmental modeling, agent-based modeling, and rigid-body dynamics. We anticipate that the new plugin framework will greatly expand the range of applications for the FEBio software suite and thus its impact.

AB - Technological advances in the last decade have enabled the study of ever more complex and physiologically relevant model membranes to help dispel the mystery surrounding the role of plasma membrane asymmetry in various cellular processes. The slowly accumulating body of experimental data is fueling renewed interest in and the need for computational methods to support interpretations and address a wide range of problems that are still not amenable to direct experimental study. The specific appeal of molecular dynamics simulations for this purpose lies in their ability to access information at atomic resolution, which is useful for the formulation of testable mechanistic hypotheses. But, the range of questions that can be addressed reliably with such simulations is determined by the appropriate construction and simulation of asymmetric bilayer models. One essential way to achieve this goal is to follow rigorous biophysical criteria and principles. In this context, we show that the requirement for a robust comparison between the properties of simulated asymmetric and symmetric model membranes is for the tension in each bilayer leaflet to be zero. Commonly used methods for constructing asymmetric bilayers, including matching the average areas of the leaflets from the corresponding symmetric systems, do not ensure zero leaflet tension, thus precluding physically realistic changes in the areas of the two leaflets. We present, to our knowledge, a new method for identifying the ideal lipid packing in bilayers with different leaflet compositions that achieves the zero-tension goal, and discuss the basic principles underlying the biophysically correct computational study of asymmetric membranes. PMID- 30297134 TI - Dynamic Migration Modes of Collective Cells. AB - Collective cell migration occurs in a diversity of physiological processes such as wound healing, cancer metastasis, and embryonic morphogenesis. In the collective context, cohesive cells may move as a translational solid, swirl as a fluid, or even rotate like a disk, with scales ranging from several to dozens of cells. In this work, an active vertex model is presented to explore the regulatory roles of social interactions of neighboring cells and environmental confinements in collective cell migration in a confluent monolayer. It is found that the competition between two kinds of intercellular social interactions-local alignment and contact inhibition of locomotion-drives the cells to self-organize into various dynamic coherent structures with a spatial correlation scale. The interplay between this intrinsic length scale and the external confinement dictates the migration modes of collective cells confined in a finite space. We also show that the local alignment-contact inhibition of locomotion coordination can induce giant density fluctuations in a confluent cell monolayer without gaps, which triggers the spontaneous breaking of orientational symmetry and leads to phase separation.

AB - Dehydrins are plant proteins that are able to protect plants from various forms of dehydrative stress such as drought, cold, and high salinity. Dehydrins can prevent enzymes from losing activity after freeze/thaw treatments. Previous studies had suggested that the dehydrins function by a molecular shield effect, essentially preventing a denatured enzyme from aggregating with another enzyme. Therefore, the larger the dehydrin, the larger the shield and theoretically the more effective the protection. Although this relationship holds for smaller dehydrins, it fails to explain why larger dehydrins are less efficient than would be predicted from their size. Using solvatochromic dyes to probe the solvent features of water, we first confirm that the dehydrins do not bind the dyes, which would interfere with interpretation of the data. We then show that the dehydrins have an effect on three solvent properties of water (dipolarity/polarizability, hydrogen-bond donor acidity and hydrogen-bond acceptor basicity), which can contribute to the protective mechanism of these proteins. Interpretation of these data suggests that although polyethylene glycol and dehydrins have similar protective effects, dehydrins may more efficiently modify the hydrogen-bonding ability of bulk water to prevent enzyme denaturation. This possibly explains why dehydrins recover slightly more enzyme activity than polyethylene glycol. PMID- 30297137 TI - Ebola virus epidemic in war-torn eastern DR Congo. PMID- 30297138 TI - Patients' experiences during the first 12 weeks after discharge in fast-track hip and knee arthroplasty - a qualitative study. AB - BACKGROUND: Due to the shortened length of stay in fast-track total hip and knee arthroplasty, patients must at a very early stage following surgery take responsibility for their postoperative care and treatment. It is important to establish if this treatment modality of fast-track is not only cost-effective, but meets patients' expectations and needs. AIM: To explore the lived experience of patients in fast-track total hip and knee arthroplasty during the first 12 weeks after discharge. METHODS: A phenomenological-hermeneutic approach was used inspired by Ricoeur's theory of narrative and interpretation. Data were collected through semi-structured interviews with 8 patients 2 and 12 weeks after discharge. FINDINGS: Through the structural analysis 3 themes emerged: 1) Dealing with transition between hospital and home, 2) Pain and self-management of medication, 3) Challenges in rehabilitation. CONCLUSION: Patients appreciated only 1 or 2 days in hospital. However, they were not sufficiently involved in the discharge planning. There was a feeling of uncertainty and being left on their own after discharge, which could affect their pain management and recovery at home. There is a need to develop in partnership with each individual patient a post discharge plan of care and rehabilitation to meet their individual needs, preferences and mode of motivation. PMID- 30297139 TI - Radiology and Political Advocacy: Characterizing Radiology Political Action Committee Donors. AB - PURPOSE: To identify factors associated with radiologist donations to radiology political action committees (PACs). MATERIALS AND METHODS: A survey was emailed to 4474 radiologists. Factors investigated include demographics, donor history, and knowledge of the federal advocacy process. Logistic regression analysis was performed to determine factors associated with donor behavior. RESULTS: In total, 336 radiologists completed the survey. Overall, 152 (46.2%) radiologists reported donating to a radiology PAC in the past year. Those with annual personal income >=$450,000 had greater odds to donate than those with annual personal income <$450,000 (odds ratio [OR]: 2.58, 95% confidence interval [CI]: 1.47-4.52; p < 0.001). More than three-quarters (77.2%, n = 254) reported limited or no knowledge of the federal advocacy process. Those with good or excellent knowledge of the federal advocacy process had greater odds to donate than those with no knowledge (OR: 2.63, 95% CI: 1.01-6.84; p = 0.047). Those with awareness that membership dues and foundation funds do not fund Society of Interventional Radiology Political Action Committee had greater odds to donate (OR: 3.54, 95% CI: 2.00, 6.25; p < 0.001). CONCLUSIONS: Radiologists' personal income and knowledge of the federal advocacy process were identified as key factors influencing donations. PAC donation may benefit from raising awareness of the federal advocacy process, as well as from targeted fundraising strategies aimed at higher earners. PMID- 30297140 TI - Participant satisfaction with dementia prevention research: Results from Home Based Assessment trial. AB - INTRODUCTION: Little is known about factors affecting motivation and satisfaction of participants in dementia prevention trials. METHODS: A Research Satisfaction Survey was administered to 422 nondemented older adults who participated in the Home-Based Assessment trial. RESULTS: Overall satisfaction was high, with means of all individual items near to above a value of 3 on a scale from 1 (worst) to 4 (best). Greater satisfaction was associated with staff-administered interviews versus automated technologies. The most liked aspects of research participation were volunteerism, opportunity to challenge and improve mental function, and positive interactions with staff. The least liked aspect was repetitiveness of the assessments. Participants requested more contact with staff and other older adults and more feedback on performance. DISCUSSION: Older adults' participation in research was primarily motivated by altruism. Methodologies that facilitate human contact, encourage feedback and novelty of tasks should be incorporated into future trial design. PMID- 30297142 TI - Delayed tension pneumocephalus following decompressive craniectomy. AB - Pneumocephalus is defined as a collection of air in the cranial cavity and is a common finding following intracranial neurosurgical procedures or following skull base fractures. The term tension pneumocephalus describes the accumulation of air under pressure such that it exerts mass effect and leads to a neurological deterioration. Whilst this is a rare event it can be life threatening and requires prompt intervention. We describe a case that occurred in a delayed fashion following a decompressive craniectomy for a severe traumatic brain injury. It was initially treated by urgent aspiration at a peripheral hospital under neurosurgical guidance. PMID- 30297141 TI - Levels of 4EBP1/eIF4E Activation in Renal Cell Carcinoma Could Differentially Predict Its Early and Late Recurrence. AB - BACKGROUND: The objective was to explore the predictive markers of late recurrence (LR) > 5 years after curative nephrectomy for renal cell carcinoma (RCC). PATIENTS AND METHODS: We retrospectively examined the data from 303 patients with localized clear cell RCC treated surgically at our institution from 1993 to 2011. Activation of the eukaryotic initiation factor (eIF)4E-binding protein 1 (4EBP1)/eIF4E axis at the mammalian target of rapamycin complex 1 (mTORC1) was evaluated in the tumor specimens. Weak, intermediate, and strong immunohistochemistry staining grades were defined for 4EBP1, phosphorylated 4EBP1, and eIF4E. The effects of clinicopathologic factors and activation level grades on tumor recurrence were analyzed using multivariate Cox regression models. To validate the present findings, we investigated clinical data from The Cancer Genome Atlas and protein/phosphoprotein data from corresponding patients from The Cancer Proteome Atlas. RESULTS: Of the 303 patients, 31 and 16 patients developed early recurrence (ER, <= 5 years) and LR, respectively. The activation levels were comparable among the subcategories of pathologic TN stage, Fuhrman grade, and microvascular and capsular invasion. Pathologic stage >= T1b, Fuhrman grade 3/4, and an intermediate or strong activation level correlated significantly with overall recurrence and ER. Strong activation of the axis and pathologic stage >= T1b were identified as independent predictors of LR. Only 2 patients with weak activation experienced recurrence (1 each with ER and LR). Similar results were confirmed by the analyses of The Cancer Genome Atlas and The Cancer Proteome Atlas data. CONCLUSION: The activation level of the axis in RCC tissues could independently predict for recurrence and differentially affect the timing of recurrence. PMID- 30297143 TI - A tax on weight loss products based on fiction, not facts. AB - The recent article by Austin et al., "Could a tax on unhealthy products sold for weight loss reduce consumer use? A novel estimation of potential taxation effects," is disappointing for its lack of objectivity and its misrepresentation. While the conclusion is not surprising, the misinformation woven into the narrative is. Ultimately, their tax solution drives up cost; fails to distinguish between those willing to pay higher prices and those who are not; and may have relatively little influence on overall purchasing behavior. PMID- 30297145 TI - In situ administration of cytokine combinations induces tumor regression in mice. AB - BACKGROUND: Recent advances in cancer immunotherapy suggest a possibility of harnessing the immune system to defeat malignant tumors, but the complex immunosuppressive microenvironment confines the therapeutic benefits to a minority of patients with solid tumors. METHODS: A lentivector-based inducible system was established to evaluate the therapeutic effect of cytokines in established tumors. Intratumoral injection of certain cytokine combination in syngeneic tumor models was conducted to assess the therapeutic potentials. FINDINGS: Doxycycline (Dox)-induced local expression of cytokine combinations exhibites a strong synergistic effect, leading to complete regression of tumors. Notably, IL12 + GMCSF+IL2 expression induces eradication of tumors in all mice tolerated with this treatment, including those bearing large tumors of ~15 mm in diameter, and generates intensive systemic antitumor immunity. Other combinations with similar immune regulatory roles also induce tumor elimination in most of mice. Moreover, intratumoral injection of chitosan/IL12 + GMCSF+IL2 solution induces a complete response in all the tested syngeneic tumor models, regardless of various tumor immunograms. INTERPRETATION: Administration of certain cytokine combinations in tumor microenvironment induces a strong synergistic antitumor response, including the recruitment of large amount of immune cells and the generation of systemic antitumor immunity. It provides a versatile method for the immunotherapy of intractable malignant neoplasms. FUND: There is no external funding supporting this study. PMID- 30297144 TI - TRPA1 inhibition ameliorates pressure overload-induced cardiac hypertrophy and fibrosis in mice. AB - BACKGROUND: Recent evidence has indicated that the transient receptor potential ankyrin 1 (TRPA1) is expressed in the cardiovascular system and implicated in the development and progression of several cardiovascular diseases. However, the effects of TRPA1 on cardiac hypertrophy development remain unclear. The aim of this study was to determine the role of TRPA1 in cardiac hypertrophy and fibrosis development. METHODS: C57BL/6J mice were subjected to transverse aortic constriction (TAC) and were orally treated with the TRPA1 selective inhibitors HC 030031 (HC) and TCS-5861528 (TCS). Morphological assessments, echocardiographic parameters, histological analyses and flow cytometry were used to evaluate cardiac hypertrophy and fibrosis. RESULTS: Human and mouse hypertrophic hearts presented with noticeably increased TRPA1 protein levels. Inhibition of TRPA1 by HC and TCS attenuated cardiac hypertrophy and preserved cardiac function after chronic pressure overload, as evidenced by increased heart weight/body weight ratio, cardiomyocyte cross-sectional area and mRNA expression of hypertrophic markers, including ANP, BNP and beta-MHC. Dramatic interstitial fibrosis was observed in the mice subjected to TAC surgery, and this was markedly attenuated in the HC and TCS treated mice. Mechanistically, the results revealed that TRPA1 inhibition ameliorated pressure overload-induced cardiac hypertrophy by negatively regulating Ca2+/calmodulin-dependent protein kinase II (CaMKII) and calcineurin signaling pathways. We also demonstrated that blocking TRPA1 decreased the proportion of M2 macrophages and reduced profibrotic cytokine levels, thereby improving cardiac fibrosis. CONCLUSIONS: TRPA1 inhibition protected against cardiac hypertrophy and suppressed cardiac dysfunction via Ca2+ dependent signal pathways and inhibition of the M2 macrophages transition. These results suggest that TRPA1 may represent a potential therapeutic drug target for cardiac hypertrophy and fibrosis.

PMID- 30297147 TI - Urinary phthalate metabolites and metabolic syndrome in U.S. adolescents: Cross sectional results from the National Health and Nutrition Examination Survey (2003 2014) data. AB - OBJECTIVE: There is limited research on the association between phthalates and metabolic syndrome (MetS). Among adolescents, phthalate exposure, which can occur from multiple sources, has been linked to several risk factors for MetS. The objective was to investigate the association between urinary phthalate metabolite concentrations (i.e., mono-ethyl phthalate (MEP), mono-n-butyl phthalate (MnBP), mono-isobutyl phthalate (MiBP), mono-benzyl phthalate (MBzP), mono-(3 carboxylpropyl) phthalate (MCPP), and di(2-ethylhexyl phthalate (DEHP)) and MetS in adolescents aged 12-19 years using the National Health and Nutrition Examination Survey (NHANES) data (2003-2014). A secondary aim was to assess if observed associations varied by a measure of socioeconomic status, economic adversity, which was defined using parental income and educational attainment as well as household food security. METHODS: We used NHANES data which included physical examination, laboratory urinalysis and fasting blood profiles, and self reported health characteristics and demographics. Physical examination and laboratory data were used to obtain values of MetS components and urinary phthalate metabolites. We created age-, sex-, and survey year-specific tertiles of creatinine-corrected urinary phthalate metabolites. Analysis was performed using appropriate weighting procedures that accounted for NHANES' complex sampling design. After univariate and bivariate analyses, we performed adjusted logistic regressions to test for associations between individual phthalate metabolites and MetS as well as MetS components and number of MetS components, separately, using the lowest tertile as the reference category. A cross-product term (phthalate metabolite*economic adversity) was subsequently added to adjusted models. RESULTS: Among 918 participants (mean age 16 years, 45% female, 18% with economic adversity), the prevalence of MetS was 5.3%. Prior to adjustment, adolescents with MetS had marginally higher concentrations of phthalate metabolites than adolescents without MetS. There was a suggestive positive association between intermediate concentrations of MnBP and odds of MetS after adjustment (T2: Odds Ratio (OR) = 2.66 (95% confidence interval: 0.98-7.24); T3: OR = 2.11 (0.71-6.27)). Males with higher MnBP concentrations had higher odds of dyslipidemia; however, associations were mostly non-significant for females. Relationships between MiBP concentrations and odds of MetS varied by sex. Males with higher concentrations of MnBP and MiBP had greater odds of having a higher number of MetS components. Relationships between phthalate metabolites and MetS did not vary by economic adversity. CONCLUSION: There was a suggestive positive association between MnBP and MetS among adolescents. Associations between phthalate metabolites and MetS as well as MetS components may vary by sex, but may not vary by economic adversity. Further research of the relationships between phthalate exposures, MetS, and potential interactions with socioeconomic factors is warranted. PMID- 30297148 TI - Exploring nurses' end-of-life care for dying patients in the ICU using focus group interviews. AB - PURPOSE: The aim of this study is to illuminate how nurses working in an intensive care unit perceive their professional duties regarding end-of-life care based on their end-of-life care experience. DESIGN AND METHODS: A qualitative research design utilising focus-group interviews was employed. Two focus groups with twelve nurses were recruited, one consisting of nurses with less than five years of clinical experience in intensive care units and the other with more than five years of experience. FINDINGS: An analysis of the nurses' explorations of end-of-life care in an intensive care unit for patients facing impending death revealed three main themes: (1) facing an extreme change in human existence, (2) being in the presence of the patient's transition and (3) being prepared as an intensive care unit nurse. These three themes covered a total of 16 subthemes. CONCLUSION: The findings of this study outline how intensive care unit nurses perceive dying patients and how they manage end-of-life care. It also illustrates how patients and their families can be included in the process, and this should be a component of nurses' education regarding end-of-life care. PMID- 30297149 TI - Lived experiences of grief of Muslim nurses caring for patients who died in an intensive care unit: A phenomenological study. AB - OBJECTIVE: To describe the meaning of the lived experiences of grief of Muslim nurses caring for patients who died in an intensive care unit. METHODOLOGY: Gadamerian philosophy was used to underpin the hermeneutic phenomenological approach followed to analyse and interpret the lived experiences of nurses who cared for patients who died in intensive care units. Fourteen nurses met the inclusion criteria. They were asked to illustrate their experiences of grief using graphic representation. This was followed by face-to-face interviews during which they were asked to narrate and reflect on their experience. The graphic representation and interview transcripts were analysed using Van Manen's approach. Lincoln and Guba's criteria were followed to establish trustworthiness. SETTING: An intensive care unit at a tertiary public hospital in West Sumatra Province, Indonesia. FINDINGS: Five major thematic categories reflecting the five life-worlds were identified: 'empathetic understanding', 'balancing self', 'avoidance', 'anticipating the future of own death', and 'relating technologies in bargaining'. CONCLUSION: This study provides further understanding of the meanings of the lived experience of grief among Muslim nurses in intensive care units. Nurses' grief arising from the loss of patients can affect their emotional, cognitive, spiritual, relational and professional well-being. The findings add further knowledge about the end of life in intensive care units. PMID- 30297150 TI - A multicase study of prolonged critical illness in the intensive care unit: Families' experiences. AB - BACKGROUND: It is widely acknowledged a critical illness is a stressful life event for not only the patient but also their family members; when an illness becomes prolonged, the impact is profound. It is suggested that as medical technologies advance, the number of days patients stay in an intensive care unit will increase. Therefore, it is important nurses understand how families experience a prolonged critical illness of their family member in an intensive care unit. OBJECTIVE: To explore the trajectory of a prolonged critical illness in the intensive care unit from the experiences of family. METHODS: A qualitative, longitudinal, multi-case design consisting of six cases from New Zealand intensive care units. Findings presented in this article only relate to the family's experiences, although patients and healthcare professionals formed part of each case. Data collection methods included observation, conversations, interviews and document review. Analysis was undertaken using thematic analysis, vignette development and trajectory mapping. FINDINGS: Relentless uncertainty dominated all phases of the trajectory for the family during a family member's prolonged critical illness in the intensive care unit. When faced with a critical illness, family shifted rapidly into a world of unknowns. Family worked hard to navigate their way through the many uncertainties that dominated each phase of their family member's illness. CONCLUSIONS: Nurses need to understand the levels of uncertainty families endure in order to provide care that meets the philosophical underpinnings of family centred care. PMID- 30297151 TI - Intensive care nurses fail to translate knowledge and skills into practice - A mixed-methods study on perceptions of oral care. AB - OBJECTIVES: To identify intensive care nurses' perceptions of oral care according to Coker et al.'s (2013) conceptual framework and to contribute to the knowledge base of oral care in intensive care. DESIGN/METHODS: This was a concurrent embedded mixed-methods design, with more weight given to the quantitative part. Participants responded to the Nursing Care related to Oral Health questionnaire, including perceptions of oral care antecedents (18 items), defining attributes (17 items), and consequences (6 items) and two open-ended questions. The data were analysed with descriptive and correlation statistics and qualitative content analysis. SETTING: Intensive care nurses (n = 88) in six general intensive care units. RESULTS: Intensive care nurses perceived that an important part of nursing care was oral care, especially to intubated patients. They perceived that the nursing staff was competent in oral care skills and had access to different kinds of equipment and supplies to provide oral care. The oral cavity was inspected on a daily basis, mostly without the use of any assessment instruments. Oral care seemed to be task-oriented, and documentation of the patients' experiences of the oral care process was rare. CONCLUSIONS: The antecedents, knowledge and skills are available to provide quality oral care, but intensive care nurses seem to have difficulties translating these components into practice. Thus they might have to shift their task-oriented approach towards oral care to a more person centred approach in order to be able to meet patients' needs. PMID- 30297152 TI - [Occupational and non occupational exposure to viral risk]. AB - The transmission of an infectious disease can occur through exposure to blood or other potentially infectious body fluids, particularly in the event of skin puncture injuries for healthcare workers, and during sexual intercourse. These situations are known as accidental blood exposures and sexual exposures respectively. Combined actions carried out have allowed to significantly reduce risks, either to healthcare professionals (by standard precautions, provision of safety devices, Hepatitis B vaccination made compulsory in the 1990s, antiretroviral post-exposure prophylaxis that should be initiated as soon as possible after exposure), or to people engaging in unprotected sex (by prevention messages, condom promotion, and antiretroviral post-exposure prophylaxis). In any case, treatment of people infected by chronic diseases such as HBV or HIV, as well as possible drug eradication of HCV, are key for decreasing post-exposure risk of disease transmission. Post-exposure prophylaxis should be initiated as early as possible and intended for use only in patients with high-risk exposures. Knowledge of source person serostatus, information of exposed person on prevention, benefits and risks of treatment, and follow-up procedure are key points. Procedures to be followed in the event of an exposure must be known by all. Arrangements set up to allow risk assessment and management of exposed people rely on hospital services operating on a permanent basis. PMID- 30297153 TI - The Thermodynamics of Development in Bioartificial Tissue Design. AB - The fabrication of bioartificial tissues with authentic structures that could assure their clinical efficacy remains a challenging problem. A new paradigm has emerged that designs bioartificial tissues as intermediate in development tissue forms, which can inherently progress autonomously on developmental pathways, self organizing their cells into tissue structures as in their in vivo development. Biological processes involved in energy exchange between co-developing tissues are responsible for cell organization into the thermodynamically robust cellular patterns of tissue structures. Bioartificial tissue design rules that aim towards in vitro recapitulation of these processes can ensure the thermodynamic operation of developing tissues, leading to formation of the cellular patterns of tissue structures. PMID- 30297154 TI - Evolution of the National Institute of Nursing Research Logic Model for Center Sustainability. AB - BACKGROUND: Logic models are tools to evaluate the effectiveness of programs. In 2013, the National Institute of Nursing Research (NINR) Logic Model for Center Sustainability was developed. PURPOSE: The purpose of this paper is to describe the process of revision and implementation of the NINR Logic Model across a continuum of NINR Exploratory Centers and Centers of Excellence. METHODS: The process for incorporating common data elements for symptom, self-management, biomarker science and precision health in the logic model is outlined. Information about the NINR Logic Model was gleaned from the National Institutes of Health Reporter, annual NINR Center Directors meetings, and from individual Center Directors. DISCUSSION: Centers utilized the model for funding applications and to guide Core administration, evaluation, Center sustainability, and/or other Center metrics. CONCLUSIONS: The revised NINR Logic Model for Center Sustainability can be a useful tool for planning and implementing center activities for center impact and sustainability. PMID- 30297155 TI - Influence of Graft Source on Postoperative Activity and Joint Laxity in Posterior Cruciate Ligament Reconstruction: A Systematic Review. AB - PURPOSE: To compare the clinical and functional outcomes of allograft and autograft reconstruction in patients with posterior cruciate ligament (PCL) deficiency. METHODS: The MEDLINE, Embase, and Cochrane Library databases were used to identify all relevant articles. Clinical outcomes including International Knee Documentation Committee, Tegner, and Lysholm scores; joint laxity; and posterior tibial displacement were evaluated. RESULTS: Among the 145 unique articles identified during the title screening, 25 studies published between 2002 and 2016 with a combined population of 900 patients were deemed eligible for inclusion in the review. Of the 900 patients, 603 were treated with autograft and 297 were treated with allograft PCL reconstruction. Five of the included studies directly compared autograft and allograft PCL reconstruction. Most studies found postoperative functional outcomes and joint laxity to improve postoperatively regardless of graft source. With only 1 exception, the included comparative studies found no significant postoperative difference in any of the functional outcome scores between patients treated with allograft and those treated with autograft. Two comparative studies found autograft reconstruction to result in significantly less posterior laxity than in the allograft group, whereas 2 comparative studies found no significant difference in posterior laxity between the 2 groups. CONCLUSIONS: PCL reconstruction results in improved functional outcome scores and joint laxity regardless of graft source. Current studies suggest there is no significant difference in postoperative functional outcomes between patients treated with autograft and those treated with allograft. Patients treated with autograft have donor-site morbidity that is not associated with allograft reconstruction. Some evidence suggests that autograft reconstruction may result in reduced posterior laxity relative to allograft reconstruction. The magnitude of this finding, however, may not be clinically significant. Our review found that decision making based on the current literature is at high risk of potential bias. LEVEL OF EVIDENCE: Level IV, systematic review of Level I to IV studies. PMID- 30297156 TI - Outcomes After Arthroscopic Rotator Interval Closure for Shoulder Instability: A Systematic Review. AB - PURPOSE: (1) To systematically assess the clinical outcomes of arthroscopic rotator interval closure (RIC) procedures for shoulder instability and (2) to report the different technical descriptions and surgical indications for this procedure. METHODS: Two independent reviewers searched 4 databases (PubMed, Embase, Web of Science, and Cochrane) from database inception until October 15, 2017. The inclusion criteria were studies that reported outcomes of shoulder stabilization using arthroscopic RIC as an isolated or adjunctive surgical procedure. The methodologic quality of studies was assessed with the Methodological Index for Non-Randomized Studies tool and Grading of Recommendations Assessment, Development and Evaluation system for randomized controlled trials. RESULTS: Fifteen studies met our search criteria (524 patients). Of the studies, 12 were graded Level IV evidence; 2, Level III; and 1, Level II. Six different RIC technique descriptions were reported, with 2 studies not defining the details of the procedure. The most common method of RIC was arthroscopic plication of the superior glenohumeral ligament to the middle glenohumeral ligament (8 of 15 studies). The most commonly used patient-reported outcome measure was the Rowe score, with all studies reporting a minimum postoperative score of 80 points. The rate of return to preinjury level of sport ranged from 22% to 100%, and the postoperative redislocation rate ranged from 0% to 16%. CONCLUSIONS: The indications for RIC were poorly reported, and the surgical techniques were inconsistent. Although most studies reported positive clinical results, the heterogeneity of outcome measures limited our ability to make definitive statements about which types of rotator interval capsular closure are warranted for select subgroups undergoing arthroscopic shoulder stabilization. LEVEL OF EVIDENCE: Level IV, systematic review of Level II through IV studies. PMID- 30297157 TI - A blooming and buzzing confusion: Buffon, Reimarus, and Kant on animal cognition. AB - Kant's views on animals have received much attention in recent years. According to some, Kant attributed the capacity for objective perceptual awareness to non human animals, even though he denied that they have concepts. This position is difficult to square with a conceptualist reading of Kant, according to which objective perceptual awareness requires concepts. Others take Kant's views on animals to imply that the mental life of animals is a blooming, buzzing confusion. In this article I provide a historical reconstruction of Kant's views on animals, relating them to eighteenth-century debates on animal cognition. I reconstruct the views of Buffon and Reimarus and show that (i) both Buffon and Reimarus adopted a conceptualist position, according to which concepts structure the cognitive experience of adult humans, and (ii) that both described the mental life of animals as a blooming, buzzing confusion. Kant's position, I argue, is virtually identical to that of Reimarus. Hence Kant's views on animals support a conceptualist reading of Kant. The article further articulates the historical antecedents of the Kantian idea that concepts structure human cognitive experience and provides a novel account of how the ideas of similarity and difference were conceptualized in eighteenth-century debates on animal cognition.

PMID- 30297160 TI - Homeless crack cocaine users: Territories and territorialities in the constitution of social support networks for health. AB - Homeless crack users are an important segment of the population living in extreme vulnerability in Brazil. In 2011, the Consultorio na Rua - CnaR (Street Clinic) was created, to improve access to health care for this population. Considering building up social support networks as a strategy to face life's difficulties, this study aims to analyse how crack users, in Rio de Janeiro, relate to territory and build social support networks to deal with their everyday life challenges and health needs. We carried out in-depth interviews with 10 homeless crack users assisted by CnaR and 11 health professionals; one Focus Group with 6 users, and Participant Observation of CnaR's work during 2014-2016. Methodology was based on the use of an analytical matrix with theoretical and empirical categories of "Territory", "Territoriality", "Social Support Networks" and "Gift". Results revealed crack users' territorialities, alternating moments of concentration and disaggregation with high geographical mobility, except in periods of strong consumption of crack. Territorialities are unstable, marked by violent Police repression. In spite of the stories of losses and ruptures, forms of sociability among users and CnaR professionals were identified, as well as with different actors in the territory. All this favoured the formation of supportive networks providing friendship, health care, and other material and symbolic goods. The systematization of the users' informal networks, usually invisible to workers and administrators, is relevant because of its potential to expand the production of care and strengthen the associations in the territory. To understand users' territorialities and the social support networks formed in their everyday life is not only innovative, but also contributes to the formulation of public policies that aim to guarantee civil rights to people in a situation of vulnerability, suffering and social exclusion.

We previously reported unexpected associations of increased numbers of B lymphocytes expressing the DNA-binding protein ARID3a with both IFN alpha (IFNalpha) expression and increased disease activity in SLE. Here, we determined that IFNalpha producing low density neutrophils (LDNs) and plasmacytoid dendritic cells (pDCs) from SLE patients exhibit strong associations between ARID3a protein expression and IFNalpha production. Moreover, SLE disease activity indices correlate most strongly with percentages of ARID3a+ LDNs, but were also associated, less significantly, with IFNalpha expression in LDNs and pDCs. Hierarchical clustering and transcriptome analyses of LDNs and pDCs revealed SLE patients with low ARID3a expression cluster with healthy controls and identified gene profiles associated with increased proportions of ARID3a- and IFNalpha expressing cells of each type. These data identify ARID3a as a potential transcription regulator of IFNalpha-related inflammatory responses and other pathways important for SLE disease activity. PMID- 30297162 TI - In Cocaine Dependence, Neural Prediction Errors During Loss Avoidance Are Increased With Cocaine Deprivation and Predict Drug Use. AB - BACKGROUND: In substance-dependent individuals, drug deprivation and drug use trigger divergent behavioral responses to environmental cues. These divergent responses are consonant with data showing that short- and long-term adaptations in dopamine signaling are similarly sensitive to state of drug use. The literature suggests a drug state-dependent role of learning in maintaining substance use; evidence linking dopamine to both reinforcement learning and addiction provides a framework to test this possibility. METHODS: In a randomized crossover design, 22 participants with current cocaine use disorder completed a probabilistic loss-learning task during functional magnetic resonance imaging while on and off cocaine (44 sessions). Another 54 participants without Axis I psychopathology served as a secondary reference group. Within-drug state and paired-subjects' learning effects were assessed with computational model-derived individual learning parameters. Model-based neuroimaging analyses evaluated effects of drug use state on neural learning signals. Relationships among model derived behavioral learning rates (alpha+, alpha-), neural prediction error signals (delta+, delta-), cocaine use, and desire to use were assessed. RESULTS: During cocaine deprivation, cocaine-dependent individuals exhibited heightened positive learning rates (alpha+), heightened neural positive prediction error (delta+) responses, and heightened association of alpha+ with neural delta+ responses. The deprivation-enhanced neural learning signals were specific to successful loss avoidance, comparable to participants without psychiatric conditions, and mediated a relationship between chronicity of drug use and desire to use cocaine. CONCLUSIONS: Neurocomputational learning signals are sensitive to drug use status and suggest that heightened reinforcement by successful avoidance of negative outcomes may contribute to drug seeking during deprivation. More generally, attention to drug use state is important for delineating substrates of addiction. PMID- 30297163 TI - Indirect adjustment of relative risks of an exposure with multiple categories for an unmeasured confounder. AB - PURPOSE: With observational epidemiologic studies, there is often concern that an unmeasured variable might confound an observed association. Investigators can assess the impact from such unmeasured variables on an observed relative risk (RR) by utilizing externally sourced information and applying an indirect adjustment procedure, for example, the "Axelson adjustment." Although simple and easy to use, this approach applies to exposure and confounder variables that are binary. Other approaches eschew specific values and provide only bounds on the potential bias. METHODS: For both multiplicative and additive RR models, we present formulae for indirect adjustment of observed RRs for unmeasured potential confounding variables when there are multiple categories. In addition, we suggest an alternative strategy to identify the characteristics that the confounder must have to explain fully the observed association. RESULTS AND CONCLUSIONS: We provide examples involving studies of pediatric computer tomography scanning and leukemia and nuclear radiation workers and smoking to demonstrate that with externally sourced information, an investigator can assess whether confounding from unmeasured factors is likely to occur. PMID- 30297164 TI - Analysis of a National Programme for Selective Internal Radiation Therapy for Colorectal Cancer Liver Metastases. AB - AIMS: Patients with chemotherapy-refractory colorectal cancer liver metastases have limited therapeutic options. Selective internal radiation therapy (SIRT) delivers yttrium 90 microspheres as a minimally invasive procedure. This prospective, single-arm, observational, service-evaluation study was part of National Health Service England Commissioning through Evaluation. METHODS: Patients eligible for treatment had histologically confirmed carcinoma with liver only/liver-dominant metastases with clinical progression during or following oxaliplatin-based and irinotecan-based chemotherapy. All patients received SIRT plus standard of care. The primary outcome was overall survival; secondary outcomes included safety, progression-free survival (PFS) and liver-specific PFS (LPFS). RESULTS: Between December 2013 and March 2017, 399 patients were treated in 10 centres with a median follow-up of 14.3 months (95% confidence interval 9.2 19.4). The median overall survival was 7.6 months (95% confidence interval 6.9 8.3). The median PFS and LPFS were 3.0 months (95% confidence interval 2.8-3.1) and 3.7 months (95% confidence interval 3.2-4.3), respectively. During the follow up period, 143 patients experienced an adverse event and 8% of the events were grade 3. CONCLUSION: Survival estimates from this pragmatic study show clinical outcomes attainable in the National Health Service comparable with previously published data. This study shows the value of a registry-based commissioning model to aid national commissioning decisions for highly specialist cancer treatments. PMID- 30297165 TI - Patella tracking calculation from patellofemoral positions at finite angles of knee flexion. AB - Patellofemoral (PF) pain is a common knee disease. Patella tracking has a significant correlation with PF pain, therefore it could be used as an index for diagnosis and treatment evaluation. Previous research has proposed a method for measuring in vivo patella tracking by means of an interpolation algorithm. The present study aimed to quantify the effect of the interpolation parameters on the accuracy of the patella tracking with a motion capture experiment. The precise patella tracking of 5 knee specimens was collected and compared with the interpolated tracking. The results showed that the total interpolation error decreased to 2 mm with the number of interpolation angles increasing to 6. The number of interpolation reference points had a slight influence on the accuracy. The findings consolidated the feasibility of using interpolation to measure the in vivo patella tracking, and can help to optimize the accuracy and efficiency of the methodology. PMID- 30297166 TI - The implementation of the ballast water management convention in the Adriatic Sea through States' cooperation: The contribution of environmental law and institutions. AB - The Adriatic Sea, a semi-enclosed and vulnerable environment, deserves special attention regarding the risk of introducing Harmful Aquatic Organisms and Pathogens via ships' ballast water as new species findings occur at an alarming rate. This species introduction vector was addressed with the 2004 International Convention for the Control and Management of Ships' Ballast Water and Sediments, which entered into force in 2017. The efficient implementation of this convention calls for Adriatic States' cooperation on environmental specifics that have not been dealt with neither by national nor by international measures yet. Based on legal and institutional data gathered, and considering the regional maritime traffic and environmental specifics, this paper reveals that the integration of current environmental law commitments as well as a better dialogue between public institutions from shipping and environmental sectors may foster the implementation of ballast water management obligations through appropriate Adriatic States' cooperation. PMID- 30297167 TI - Handling of Missing Outcome Data in Acute Stroke Trials: Advantages of Multiple Imputation Using Baseline and Postbaseline Variables. AB - BACKGROUND: In acute stroke randomized trials, missingness of final functional outcome data reduces study power and potentially biases findings of treatment effect. Best methods for handling missing outcome data have not been well delineated for diseases with monophasic onset and subsequent improvement, like acute stroke. METHODS: We simulated data missingness in the public dataset of the landmark, second NINDS-tPA trial, by randomly removing 5%-25% of actual values for the 3-month modified Rankin Scale (mRS) of global disability. We evaluated 5 missing data-handling methods: complete case analysis (CCA), worst case imputation (WCI), last observation carried forward (LOCF), multiple imputation using baseline covariates only (MI-B), and multiple imputation using baseline and postbaseline observations (MI-BP). RESULTS: With the original trial's 333 patients, tissue plasminogen activator was associated with 3-month disability benefit, both for mRS dichotomized at 0-1 (P = .014) and shift analysis (P = .035). Distance (root mean square error) of imputed from actual mRS values was best for LOCF (1.17) and MI-BP (1.28), intermediate for MI-B (1.89) and worst for WCI (3.77). Directional bias (mean difference) was least for MI-BP (.01) and MI-B (-.16), intermediate for LOCF (-.37), and worst for WCI (-3.22). Preservation of formally positive results was greatest for MI-BP and LOCF (preserved at all missingness rates), intermediate for CCA and MI-B (preserved only with missingness <10%-20%), and least for WCI (preserved only with missingness <5% 20%). CONCLUSIONS: For acute stroke trials, multiple imputation using baseline and postbaseline observations is an advantageous approach to missing outcome data handling, yielding high accuracy, reduced directional bias, and greater preservation of study power. PMID- 30297168 TI - History of Carotid Occlusions: The Contribution of Egas Moniz. AB - OBJECTIVE: To describe the first cases of carotid occlusions identified by the Portuguese neurologist Egas Moniz while performing the cerebral angiography he invented. METHODS: We reviewed the publications of Egas Moniz on the subject of cerebral angiography and ischemic stroke. RESULTS: We identified the first description of carotid occlusion a situation unknown until then. Also, some of the carotid occlusions he described were suggestive of dissection an unknown situation. Nevertheless, he admitted the role of trauma in such cases by lesioning the intimal layer and he also described the characteristic post-bulbar "bezel-like" image of dissection. CONCLUSIONS: In 1936 Egas Moniz described, for the first time, one case of carotid occlusion a situation unknown until then. He also described some of the characteristic aspects of carotid dissections. Carotid occlusions were only thoroughly described in English literature more than a decade later with the well-known work of Miller Fisher, in 1951. PMID- 30297169 TI - Epidemiology and Outcomes of Ischemic Stroke and Transient Ischemic Attack in the Adult and Geriatric Population. AB - BACKGROUND: Rate of ischemic strokes and transient ischemic attacks (TIAs) increases with age. There is lack of evidence on how age affects treatment strategies and outcomes. Our aim is to compare epidemiology of ischemic strokes and TIAs in adult and geriatric populations including risk factors, treatment delivered, and outcomes. DESIGN: We designed a retrospective cross-sectional review of patients admitted to neurology with diagnosis of stroke or TIA from 2010 to 2015. Obtained variables were: age, sex, risk factors, acute therapy, National Institutes of Health Stroke Scale on admission and discharge, and disposition. Means, confidence intervals, or percentages were calculated as appropriate. RESULTS: Around 1,457 patients were divided into two groups: younger than 80 (n = 968) and 80 and older (n = 487). Rates of stroke and TIA were similar across younger and older groups (11% versus 12% TIA and 89% versus 88% stroke, respectively). Younger patients had lower admission National Institutes of Health Stroke Scale (mean 4.64 versus 7.84 in older group) and greater improvement on discharge (mean change -1.51 versus -1.29 accordingly). Older patients received tissue-type plasminogen activator (tPA) more often than younger patients, but no difference in rates of thrombectomy between groups. Older patients were more likely to have hypertension, atrial fibrillation, coronary artery disease, and less likely to be a smoker. On discharge, younger patients with stroke were discharged home or to acute rehab more frequently, regardless of tPA administration. CONCLUSIONS: Older patients had more comorbidities, received tPA more often, and had worse outcomes regardless of use of intravenous tPA or thrombectomy, and were more frequently institutionalized after discharge. PMID- 30297170 TI - Secular Trends in the Background of Intracerebral Hemorrhage from 2010 to 2015. AB - OBJECTIVE: Direct oral anticoagulants (DOACs) were recently introduced for the clinical use in stroke prevention, and they are reported to show a lower risk of intracerebral hemorrhage (ICH) compared to warfarin. We were interested to know whether there is any change in clinical backgrounds of ICH patients to date. METHODS: From 2010 to 2015, ICH patients admitted to our hospital were consecutively screened (n = 658). Hematoma size was assessed by brain computed tomography images on admission. Outcome was measured by the modified Rankin Scale, and favorable outcome was defined as modified Rankin Scale 0-2. Biennial trends were compared in 3 periods, P1: 2010-2011, P2: 2012-2013, and P3: 2014 2015. RESULTS: The percentage of ICH patients taking antithrombotics had been slightly decreasing (P = .245: [P1] 33.0%, [P2] 27.4%, and [P3] 26.2%). The frequency of patients taking antiplatelets had significantly decreased (P = .001: [P1] 50.7%, [P2] 44.3%, and [P3] 22.8%), and those taking DOACs had significantly increased (P = .001: [P1] 1.4%, [P2] 4.9%, and [P3] 19.3%). Frequency of favorable outcomes in patients taking antithrombotics was slightly increased in P3 compared to P1 and P2 (23.3%, 21.1%, and 21.3%, respectively). There was no significant difference in hematoma size between patients taking warfarin and DOACs. CONCLUSIONS: Number of ICH patients taking antithrombotics has been slightly decreasing and the percentage taking DOACs among ICH has been increasing for 6years. PMID- 30297171 TI - Analysis of Availability and Access of Anti-myeloma Drugs and Impact on the Management of Multiple Myeloma in Latin American Countries. AB - INTRODUCTION: Latin American countries (LATAMC) represent a large fraction of patients treated for multiple myeloma (MM) worldwide. In order to understand the difficulty of access to anti-myeloma therapy in LATAMC, we designed this study that explores areas involved in the availability of drugs, such as health care systems, approval times, coverage of new agents, old drugs, use of generics, and the first-line treatments. MATERIAL AND METHODS: We collected data from 16 countries in 2015. RESULTS: The majority of LATAMC (88%; n = 14) had mixed public and private coverage, with patients with MM cared for in public institutions. Although bortezomib and lenalidomide were approved in 100% and 73% in LATAMC, these figures did not translate to real-world practice as one-half of the nations reported unequal access to the new agents (thalidomide, bortezomib, and lenalidomide) in both public and private systems. Conversely, cheaper old drugs, represented by melphalan, were not available commercially in 44% (n = 7) of nations. Thus, first-line MM treatments for old and young patients in public practice were triplets with thalidomide-alkylating agent-steroid, whereas in private practice, treatments involved bortezomib-alkylating agent-steroid. An alarming rate of 30% of the nations reported suboptimal regimens (eg, VAD [vincristine, adriamycin, and dexamethasone]) or the impossibility of transplantation. CONCLUSION: Our data indicates that bortezomib and transplant are still an unmet medical necessity in public systems. In the complex puzzle of myeloma drug access in LATAMC, important issues, such as the adjustment of disparities between health systems, the incorporation of new drugs with an economic cost-effectiveness view, and the re-establishment of essential old drugs, can be a platform to the future. PMID- 30297172 TI - Smartphone-based differential pulse amperometry system for real-time monitoring of levodopa with carbon nanotubes and gold nanoparticles modified screen-printing electrodes. AB - Parkinson's disease caused by lack of dopamine in brain is a common neurodegenerative disorder. The traditional treatment is to replenish levodopa since it could pass through blood brain barrier and form dopamine. However, its accumulation can cause patients' movement disorders and uncontrollable emotion. Therefore, it is critical to control the levodopa dosage accuracy to improve the curative effect in clinical. In this study, a smartphone-based electrochemical detection system was developed for rapid monitoring of levodopa. The system involved a disposable sensor, a hand-held electrochemical detector, and a smartphone with designed application. Single-wall carbon nanotubes and gold nanoparticles modified screen-printed electrodes were used to convert and amplify the electrochemical current signals upon presence of levodopa molecules. The electrochemical detectors were used to generate electrochemical excitation signals and detect the resultant currents. Smartphone was connected to the detector, which was used to control the detector, calculate data, and plot graph in real-time. The smartphone-based differential pulse amperometry system was demonstrated to monitor levodopa at concentrations as low as 0.5 uM in human serum. Furthermore, it has also been verified to be able to distinguish levodopa from other representative substances in the body. Therefore, its performance was more sensitive and rapid than electrochemical workstation. With these advantages, the system can be used in the field of point-of-care testing (POCT) to detect levodopa and provide the possibility to solve clinical demand for levodopa detection. PMID- 30297173 TI - Detection of bacterial metabolism in lag-phase using impedance spectroscopy of agar-integrated 3D microelectrodes. AB - Traditional methods for detection of metabolically-active bacterial cells, while effective, require several days to complete. Development of sensitive electrical biosensors is highly desirable for rapid detection and counting of pathogens in food, water, or clinical samples. Herein, we develop a highly-sensitive non Faradaic impedance sensor which detects metabolic activity of E. coli cells in a mere 1 MUl of sample volume and without any sample filtration/purification. The three dimensional (3D) interdigitated electrodes (IDEs) along with self-assembled gold-nickel (Au-Ni) nanostructures significantly amplify the sensitivity by increasing the sensing area almost three-fold. The developed microsystem is integrated with an agar-based growth medium and monitors the metabolism of bacterial cells, enabling bacterial detection in approximately one hour after inoculation, i.e. in the lag-phase. Incorporation of a secondary agar layer as a biocompatible passivation layer protects the IDEs from potential Faradaic reactions and enhances sensitivity to modulation of the non-Faradaic impedance due to cellular metabolism. The resultant label-free sensor is capable of selective identification of metabolizing cells (vs. dead cells) across a wide linear range (10-1000 cells/MUl). These results help pave the way for rapid antibacterial susceptibility testing at the point-of-need, which is currently a major challenge in healthcare. PMID- 30297174 TI - Affinity sensor for haemoglobin A1c based on single-walled carbon nanotube field effect transistor and fructosyl amino acid binding protein. AB - Haemoglobin A1c (HbA1c) is a significant glycaemic marker for diabetes mellitus. The level of HbA1c reflects the mean blood glucose level over the prior 2-3 months and it is useful for the assessment of therapeutic effectiveness and for diagnosis. In this study, we report the label-free affinity sensor for HbA1c based on the chemiresistor-type field-effect transistor, which has a simple sensor configuration. Single-walled carbon nanotubes (SWNTs) were used as the transducing element. The fructosyl amino acid binding protein from Rhizobium radiobacter (SocA), which binds to alpha-fructosyl amino acid specifically, was used as the biorecognition element for fructosyl valine (FV), the product of the proteolytic hydrolysis of HbA1c. The developed sensor shows the ability to measure as low as 1.2 nM FV, which is 14-fold more sensitive compared to the previously reported fluorescence-based sensor using SocA. This sensor also exhibits high specificity where no significant response is observed from either fructosyl lysine (FK) or glucose, which are potential interferents. FK is the epsilon-fructosyl amino acid from glycated albumin, another glycated protein, whereas glucose is naturally present at very high concentration in the blood. We propose that the modulation of the surface charges on the SWNTs caused by the conformational change in SocA upon ligand binding leads to the proportionate changes in the number of carriers in the SWNT channel. PMID- 30297175 TI - Preselection of Lung Cancer Cases Using FGFR1 mRNA and Gene Copy Number for Treatment With Ponatinib. AB - INTRODUCTION: Preclinically, high epidermal growth factor receptor 1 (FGFR1) messenger RNA (FGFR1-MRNA) and FGFR1 amplification (FGFR1-AMP) predicted sensitivity to fibroblast growth factor receptor inhibitors in non-small-cell lung cancer and small-cell lung cancer cell lines. KRAS mutations did not preclude sensitivity. PATIENTS AND METHODS: Metastatic EGFR- and ALK-negative lung cancers were screened for FGFR1-MRNA by in-situ hybridization (ISH) and FGFR1-AMP by silver in-situ hybridization (SISH). Patients with positive findings were offered ponatinib, a multi-kinase inhibitor of FGFR1-4. Differences in overall survival (OS) between cohorts were assessed by the log-rank test. Association of FGFR1 positivity with clinicopathologic features were assessed by Fisher exact test and Kruskal-Wallis rank sum test. RESULTS: A total of 171 cases were prescreened: 9 (7.3%) of 123 SISH+; 53 (42.1%) of 126 ISH+; and 6 cases concordantly positive for SISH and ISH. SISH+ cases had fewer coincident KRAS mutations (P = .03) than SISH- cases, and ISH+ cases had worse OS (P = .020) than ISH- cases. Data distributions suggested a distinct higher positivity cut point for FGFR1 ISH (>= 20%), occurring in 29 (23%) of 126 cases, was associated with small-cell lung cancer histology (P = .022), soft tissue metastases (P = .050) and shorter OS (P = .031). Four patients received ponatinib on study: All ISH+ by the initial cut point, 2 of 4 by higher cut point, 1 of 4 SISH+. Tolerability was poor. The best response for the 2 higher ISH cases was stable disease and progressive disease for the 2 lower ISH cases. CONCLUSION: Elevated FGFR1-MRNA is more common than FGFR1-AMP and associated with worse OS. Higher FGFR1 mRNA expression may be associated with a specific phenotype and is worthy of further exploration. Ponatinib's poor tolerance suggests further fibroblast growth factor receptor exploration in ISH+ cases should utilize more selective FGFR1 inhibitors. PMID- 30297176 TI - Exploring the Diversity of Plant Metabolism. AB - Plants produce a huge array of metabolites, far more than those produced by most other organisms. Unraveling this diversity and its underlying genetic variation has attracted increasing research attention. Post-genomic profiling platforms have enabled the marriage and mining of the enormous amount of phenotypic and genetic diversity. We review here achievements to date and challenges remaining that are associated with plant metabolic research using multi-omic strategies. We focus mainly on strategies adopted in investigating the diversity of plant metabolism and its underlying features. Recent advances in linking metabotypes with phenotypic and genotypic traits are also discussed. Taken together, we conclude that exploring the diversity of metabolism could provide new insights into plant evolution and domestication. PMID- 30297177 TI - Fully covered self-expandable metallic stents for malignant airway disorders. AB - BACKGROUND: Airway stenting is an established procedure for treating airway stenosis and fistulas. The AERO stent (Merit Medical Systems, South Jordan, UT, USA), a relatively new, fully covered, self-expandable metallic stent, was approved in Japan in 2014. This study evaluated the efficacy and safety of this stent for malignant airway disorders. METHODS: Medical records of all patients at a single center, in whom the AERO stent was deployed between February 2015 and December 2017, were retrospectively reviewed. All procedures were performed using rigid and flexible bronchoscopes under general anesthesia. RESULTS: A total of 42 procedures were performed in 36 patients: 37 for treatment of airway stenosis and five for tracheoesophageal fistula. The AERO stents were successfully placed in 41 of 42 (98%) cases. The amount of oxygen could be reduced in 78% of patients who required oxygen therapy. Pulmonary function, including vital capacity, forced expiratory volume in 1 second, and peak expiratory flow, improved significantly after the procedures. Complications occurred in 14 (33%) cases; the most frequent complication was migration (6 cases). Fourteen stents were successfully removed without any complications. CONCLUSIONS: Placement of an AERO stent was effective and acceptably safe for treating malignant airway disorders. Because the AERO stent can be removed safely, it can be used for palliation or as a bridge to chemoradiotherapy. PMID- 30297178 TI - Medical Management of Acute Facial Paralysis. AB - Acute facial paralysis (FP) describes acute onset of partial or complete weakness of the facial muscles innervated by the facial nerve. Acute FP occurs within a few hours to days. The differential diagnosis is broad; however, the most common cause is viral-associated Bell Palsy. A comprehensive history and physical examination are essential in arriving at a diagnosis. Medical treatment for acute FP depends on the specific diagnosis; however, corticosteroids and antiviral medications are the cornerstone of therapy. Lack of recovery after 4 months should prompt further diagnostic workup. PMID- 30297179 TI - Management of Flaccid Facial Paralysis of Less Than Two Years' Duration. AB - Flaccid facial paralysis results in disfiguring facial changes. The treatment of flaccid facial paralysis is complex and treatment approaches should be determined based on duration and the causes of paralysis, status and accessibility of the affected facial nerve, medical comorbidities, and patient-specific goals. Although primary nerve repair is the preferred treatment strategy when possible, nerve substitution procedures are the mainstay of treatment for patients with flaccid facial paralysis of less than 2 years duration.

PMID- 30297183 TI - Multidisciplinary Tracheostomy Care: How Collaboratives Drive Quality Improvement. AB - There have been reports of successful quality-improvement initiatives surrounding tracheostomy care for more than a decade, but widespread adoption of best practices has not been universal. Five key drivers have been found to improve the quality of care for tracheostomy patients: multidisciplinary synchronous ward rounds, standardization of care protocols, appropriate interdisciplinary education and staff allocation, patient and family involvement, and use of data to drive improvement. The Global Tracheostomy Collaborative is a quality improvement collaborative dedicated to improving the care of tracheostomy patients worldwide through communication, dissemination, and implementation of proven strategies based on these 5 key drivers. PMID- 30297184 TI - Is the Birthing Unit Design Spatial Evaluation Tool valid for diverse groups? AB - BACKGROUND: Awareness of the impact of the built environment on health care outcomes and experiences has led to efforts to redesign birthing environments. The Birth Unit Design Spatial Evaluation Tool was developed to inform such improvements, but it has only been validated with caseload midwives and women birthing in caseload models of care. AIM: To assess the content validity of the tool with four new participant groups: Birth unit midwives, Aboriginal or Torres Strait Islander women; women who had anticipated a vaginal birth after a caesarean; and women from refugee or culturally and linguistically diverse backgrounds. METHODS: Participants completed a Likert-scale survey to rate the relevance of The Birth Unit Design Spatial Evaluation Tool's 69 items. Item-level content validity and Survey-level validity indices were calculated, with the achievement of validity set at >0.78 and >0.9 respectively. RESULTS: Item-level content validity was achieved on 37 items for birth unit midwives (n=10); 35 items for Aboriginal or Torres Strait Islander women (n=6); 33 items for women who had anticipated a vaginal birth after a caesarean (n=6); and 28 items for women from refugee or culturally and linguistically diverse backgrounds (n=20). Survey-level content validity was not demonstrated in any group. CONCLUSION: Birth environment design remains significant to women and midwives, but the Birth Unit Design Spatial Evaluation Tool was not validated for these participant groups. Further research is needed, using innovative methodologies to address the subconscious level on which environment may influence experience and to disentangle the influence of confounding factors. PMID- 30297185 TI - [Surgical treatment of BPO: Standard and innovations]. AB - INTRODUCTION AND OBJECTIVE: Surgical management of benign prostatic hyperplasia has dramatically changed in the recent years towards higher proportion of endoscopic treatment and fewer perioperative complications. Nevertheless the question of urinary and sexual quality of life after surgical treatment remains partially unresolved with a high proportion of retrograde ejaculation after conventional surgical treatments. Therefore mini-invasive alternatives to conventional surgery have been proposed. The objective of this literature review was to provide an overview of the alternatives to monopolar TURP currently available in France. MATERIAL AND METHOD: A non-systematic review of the scientific literature was conducted from the PubMed database to retrieve the most relevant scientific publications. A first research was cross-referenced with the results of literature reviews already published and enriched by the authors of this review. A synthesis is proposed for each alternative technique mentioning its level of clinical development, but also its potential advantages and disadvantages compared to conventional surgical techniques. RESULTS: The quality of life of patients after surgical or interventional management has become the main priority of urologists since the risks of perioperative complication have been reduced by the use of laser or bipolar endoscopic techniques. Thanks to the development of minimally invasive alternatives that are better and better evaluated by randomized trials versus interventional simulation and conventional surgical treatment, more personalized care is possible. Patients' expectations and their individual risk factors can thus be placed at the center of the therapeutic decision and the preoperative information. CONCLUSION: The surgical and interventional management of LUTS due to BPH has evolved to lower perioperative morbidity with the help of numerous technological developments. Mini-invasive alternatives to standard treatment have also been proposed in order to improve the quality of postoperative sexual life. These alternatives provide significant improvement in LUTS that remains lower than after conventional treatments. Somme of these alternative are also not fully supported by clinical trials, which should urge urologists to act with caution when proposing these alternatives in daily clinical practice. PMID- 30297186 TI - The narrow-sense and common single nucleotide polymorphism heritability of early repolarization. AB - BACKGROUND: Early repolarization (ER) is a risk marker for sudden cardiac death. Higher risk is associated with horizontal/descending ST-segment ER in the inferior or inferolateral ECG leads. Studies in family cohorts have demonstrated substantial heritability for the ER pattern, but genome-wide association studies (GWAS) have failed to identify statistically significant and replicable genetic signals. METHODS AND RESULTS: We assessed the narrow-sense and common single nucleotide polymorphism (SNP) heritability of ER and ER subtypes using ECG data from 5829 individuals (TwinsUK, BRIGHT and GRAPHIC cohorts). ER prevalence was 8.3%. In 455 monozygous vs 808 dizygous twin pairs, concordances and twin correlations for ER subtypes (except horizontal/descending ST-segment ER) were higher and familial resemblance (except notched ER) was significant. Narrow-sense heritability estimates derived from 1263 female twin pairs using the structural equation program Mx ranged from 0.00-0.47 and common SNP heritability estimates derived from 4009 unrelated individuals of both sexes using Genome-wide Restricted Maximum Likelihood (GREML) ranged from 0.00-0.36, but none were statistically significant. CONCLUSION: From our data, ER shows limited genetic predisposition. There appears to be significant environmental influence and these modest narrow-sense and common SNP heritability estimates may explain why previous GWAS have been unsuccessful. PMID- 30297187 TI - A successful crowdfunding project for eHealth research on grown-up congenital heart disease patients. AB - BACKGROUND: Scarce data on crowdfunding report a maximal funding of ?10.000,-, and state that research is needed to attract attention of larger granting organizations. The aims of this project were 1) to fund an eHealth study in grown up congenital heart disease (GUCH) patients 2) to contemplate on critical success factors. METHODS: After peer review of the Dutch Heart Foundation a project was published at a donation platform, which was open for donations during a predetermined period of two months. Copywriters were hired to create an easy-to understand message to donors. A video teaser was created with a motivated patient, and rewards were available. The crowdfunding targeted ?25.000 and the Dutch Heart Foundation doubled the donations to ?50.000, and return of donations were guaranteed in case this was not met. RESULTS: Initially, donations came from the investigators' private inner circle. In total, 44 potential donors were contacted, but refused to donate originally. Multiple (social) media campaigns were published to promote the project, and an offline mailing was sent to contributors to the Dutch Heart Foundation. During the project support emerged, resulting in extra donations and public awareness. In the lasts three weeks, after sufficient private donations, five major donors decided to support the project. The project became a big success: the predetermined target was exceeded and a total of ?74.450,- was raised. CONCLUSION: Innovative crowdfunding gave the opportunity to start eHealth research in GUCH patients. Critical success factors include support of a professional organization, support of stakeholders, and easy to-understand messages. PMID- 30297188 TI - Cardiac resynchronization therapy in congenital heart disease: Results from the German National Register for Congenital Heart Defects. AB - BACKGROUND: Cardiac resynchronization therapy (CRT) is an established option for patients with heart failure. Limited data exists on indications and outcome of CRT in contemporary congenital heart disease (CHD) patients. METHODS AND RESULTS: All patients with CRT registered in the German National Register for Congenital Heart Defects were systematically identified. We analysed data on demographics, type of congenital defect as well as repair, associated conditions, indication for CRT, heart failure medication, combination with a defibrillator or pacemaker and outcome. Overall, 65 patients with CRT were identified. The most common congenital diagnoses were Tetralogy of Fallot (n = 11), congenitally corrected transposition of the great arteries (ccTGA) (n = 9) and double outlet right ventricle (n = 6). The majority of patients (n = 48, 87%) had conventional antibradycardia pacing or ICD indications. Of these, the majority (n = 44) underwent an upgrade to a CRT system to avoid the detrimental consequences of longstanding conventional ventricular single-site pacing, whereas four patients required an ICD due to heart failure and a history of malignant ventricular tachycardia. During a median follow-up of 6.9 years 19 patients developed complications: 16 patients experienced pacemaker lead dysfunction and 3 patients pacemaker infection. CONCLUSIONS: The current study based on a large national register for CHD shows that CRT is feasible and can be used as an adjunct in the heart failure treatment of selected CHD patients. Uptake of this therapy proved to be low in this nationwide study and CRT implantation was largely used in patients with a pre-existing pacing indication or those requiring an ICD. PMID- 30297189 TI - Heart failure and the risk of acute kidney injury in relation to ejection fraction in patients undergoing coronary artery bypass grafting. AB - BACKGROUND: We studied the association between heart failure with reduced or preserved ejection fraction (EF) and the risk of acute kidney injury (AKI) in patients undergoing coronary artery bypass surgery (CABG). METHODS: We included all patients who underwent isolated CABG in Sweden 2003 to 2013. AKI was defined according to the Kidney Disease Improving Global Outcomes definition, as an increase in postoperative serum creatinine concentration by >=26 MUmol/L or >=50%, compared to preoperative values. Adjusted odds ratios (OR) for AKI were calculated using logistic regression for patients with and without heart failure, and among patients with heart failure, by EF categories (<30% severely reduced; 30-40% moderately reduced; >=50% preserved). RESULTS: Included were 36,403 patients of whom 3914 (11%) had heart failure. In patients with heart failure, 26% developed AKI compared with 14% in patients without heart failure. After adjustment for background characteristics, including preoperative kidney function and EF, the OR for AKI was 1.12 (95% CI 1.02-1.23) in patients with heart failure compared with no heart failure. Among patients with heart failure, the adjusted OR for AKI among patients with EF <30% vs. >=50% was 1.32 (95% CI 1.06-1.65) and for 30-49% vs. >=50% 1.06 (95% CI 0.87-1.28), respectively. CONCLUSION: Patients with heart failure who underwent CABG had an increased risk for AKI postoperatively even after adjustment for comorbidity such as EF. Among patients with heart failure, having a severely reduced EF was associated with AKI compared to patents with preserved EF. PMID- 30297190 TI - On the prospect of serum exosomal miRNA profiling and protein biomarkers for the diagnosis of ascending aortic dilatation in patients with bicuspid and tricuspid aortic valve. AB - BACKGROUND: To determine the impact of circulating miRNA and protein activity on the severity of ascending aortic dilatation in patients with bicuspid (BAV) and tricuspid aortic valve (TAV). METHODS: By reverse transcription polymerase chain reaction, exosomal circulating expression levels (versus healthy aorta) of miRNAs and absolute levels of transforming growth factor beta (TGF-beta), matrix metalloproteinases (MMP-2, -3 and -9), tissue inhibitors (TIMP-1, -2, -3 and -4), and soluble receptors for advanced glycation end products AGEs (sRAGE) were evaluated in ascending dilated aortas of 71 patients with different valve morphotype. RESULTS: Less-dilated ascending aorta exhibited a specific miRNA signature (i.e., miR-126 miR-15b, miR-195, miR-221, miR24, miR-30b and miR-320a), which was statistically different from that of severely-dilated ascending aorta. Among these analytes, miR-15b was the most significant (p < 0.001) and resulted as an independent predictor of aortic dilatation (beta = -1.099, p = 0.041). When patients were grouped according to aortic valve morphology, miRNAs and protein proteolytic activity were different between BAV and TAV in the expression level of miR-133a, miR-155, miR-320a, miR-34a(#000425), miR-34a(#000426), miR-494 and measurements of TGF-beta and MMP-3, MMP-9, TIMP-4. The circulating level of miR 34a(#000426) was negatively correlated to the aortic wall elasticity of bicuspid patients (R = -0.653 and p = 0.011), suggesting an apparent different mechanism of aortic wall degeneration specific for BAV. CONCLUSIONS: Taken these biomarkers together, we demonstrated that the severity of aortic size and valve morphology differently modulates miRNA analytes and protein proteolytic activity in patients with ascending aortic dilatation, and this may be useful to design new therapies that inhibit miRNAs. PMID- 30297191 TI - Epicardial adipose tissue and cardiovascular diseases. AB - Obesity is a heterogeneous disease with different degrees of cardiovascular (CV) and metabolic manifestations. Certain ectopic fat depots may contribute to obesity-related CV risk and may explain part of the risk differential observed in metabolically healthy obese and the so called "obesity paradox". The growing interest towards the potential impact of epicardial adipose tissue (EAT) in cardiovascular (CV) risk has led to deepen its biological function. Genetic, epigenetic and environmental factors may drive the shift towards a dysfunctional EAT characterized by a pro-inflammatory and pro-fibrotic phenotype. Due to the close anatomic proximity to coronary arteries, a thicker and dysfunctional EAT actively contribute to development and progression of coronary atherosclerosis. Beside classical paracrine transmission, EAT may directly release mediators into the vasa vasorum of the coronary arterial wall, a mechanism referred to as "vasocrine". Similarly, the pro-inflammatory and pro-fibrotic secretome characterizing dysfunctional EAT may impair cardiac structure and function, thus being implicated in the pathogenesis of diastolic heart failure and atrial fibrillation. The development of 3D imaging techniques have paved the way for clarifying the causative role of EAT in CV pathophysiology, the use of EAT volume/thickness in CV risk stratification and potential cardio-protective effects of EAT reduction. The aim of this narrative review is to update current knowledge on the pathophysiological functions of EAT, focusing on basic mechanisms and potential clinical implications.

PMID- 30297193 TI - Coma, Seizures, Atrioventricular Block, and Hypoglycemia in an ADB-FUBINACA Body Packer. AB - BACKGROUND: Synthetic cannabinoid intoxication has become difficult to diagnose and manage in the United States, in part due to varying clinical effects within this heterogeneous group of compounds. CASE REPORT: A 38-year-old man was admitted with altered mental status and bradycardia. He demonstrated progressive encephalopathy, seizure activity, second-degree atrioventricular block type I, respiratory failure, hypotension, hypothermia, and hypoglycemia. A computed tomography scan of the abdomen and pelvis revealed multiple packages in the patient's stomach and rectum. Multiple attempts at gastrointestinal decontamination were unsuccessful. On hospital day 8 the patient developed hypertensive emergency and was taken to the operating room for exploratory laparotomy. Twenty-two poorly wrapped packages were removed from the bowel. Postoperatively the patient demonstrated both generalized and focal seizure activity. His mental status slowly returned to baseline over the period of about 1 week and he was ultimately discharged without neurological sequelae after 1 month. Analysis of patient serum, urine, and plant matter from the packages identified cannabis and 2.N-(1-amino-3,3-dimethyl-1-oxobutan-2-yl)-1-(4 fluorobenzyl)-1H-indazole-3-carboxamide (ADB-FUBINACA). WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The case presented demonstrates the suspected toxidrome associated with severe ADB-FUBINACA intoxication, including mental status depression, bradycardia, autonomic instability, seizure, hypoglycemia, and hypothermia. Although the patient had simultaneous exposure to cannabis, his constellation of symptoms is not consistent with cannabis intoxication. A previous animal model supports the potential of this specific synthetic cannabinoid to cause the reported toxidrome. PMID- 30297194 TI - Aphthous Stomatitis Major in a 4-Month-Old Infant.

AB - Tophaceous deposits in lumbar spine is considered a rare condition. We report the case of a 44-year-old patient with low back pain and radiculopathy. Radiographs revealed lytic spondylolisthesis in L5. Magnetic resonance imaging showed hypointense signal on T1 and a heterogeneous signal on T2 located in the L4-L5 interspinous space and in the left facet joint that invades left neuroforamen. The left knee ultrasound showed "double contour" of the medial femoral condyle. Decompressive laminectomy with arthrodesis at the level of L5-S1 was performed. The histological examination revealed amorphous material with a foreign body giant cell reaction. PMID- 30297197 TI - Aphthous Stomatitis and Laryngitis, Another Form of Presentation of an IgG4 Related Disease? AB - IgG4-related disease is characterized by a lymphoplasmacytic infiltrate rich in IgG4-positive plasma cells, storiform fibrosis and obliterative phlebitis. It can present as parotid gland enlargement, tubulointerstitial nephritis, retroperitoneal fibrosis or pancreatitis, although nearly any organ can be affected. We report the case of a 37-year-old woman who presented with severe dysphonia and recurrent painful aphthous ulcers, with histopathological findings at the level of the larynx that revealed a lymphoplasmacytic infiltrate and IgG4 positivity. In addition, extensive studies were performed to rule out other diseases. Thus the diagnosis was IgG4-related laryngitis, an exceptional finding in the literature.

PMID- 30297200 TI - [Pemetrexed-induced eyelid edema]. AB - BACKGROUND: Drug-induced eyelid edemas are rare. Herein, we describe a patient who developed this type of edema under chemotherapy. PATIENTS AND METHODS: A 56 year-old male patient with a history of hypertension and adenocarcinoma of the lung with brain metastases consulted for incipient non-itchy eyelid edema with progressive worsening. The swelling occurred after 3 cycles of pemetrexed carboplatin. There was no evidence of any other cause of edema. A diagnosis of pemetrexed-induced eyelid edema was made. Given the efficacy of this treatment and the patient's consent thereto, it was maintained. DISCUSSION: Palpebral edemas secondary to pemetrexed are very rare, with only 22 published cases in the literature. Other differential diagnoses must be ruled out before considering this etiology. The pathogenesis of eyelid edema remains unknown. One hypothesis is capillary protein leakage inducing swelling in soft tissue and non-malignant effusion, as has been suggested for docetaxel. Other agents such as tyrosine kinase inhibitors (imatinib and nilotinib) and mTOR inhibitors (sirolimus) may also cause eyelid edema. Treatment of eyelid edema is difficult and one case of surgical treatment has been published with good results and no recurrence after 6 months. PMID- 30297199 TI - Endogenous secretory RAGE increases with improvements in body composition and is associated with markers of adipocyte health. AB - BACKGROUND AND AIMS: The receptor for advanced glycation end products (RAGE) is implicated in obesogenesis. Conversely, soluble RAGE (sRAGE) competitively inhibits RAGE. Our aim was to determine the effects of weight-loss via alternate day fasting (ADF) on sRAGE isoforms and evaluate potential relationships with body composition. METHODS AND RESULTS: 42 obese participants were randomized to control (CON) or ADF. For 24 weeks, the ADF group consumed 25% or 125% of their caloric requirements on alternating days while the CON group did not change their diet. Body fat was measured via DXA, visceral fat (VAT) via MRI and subcutaneous fat (SAT) was derived by subtracting VAT from total fat. sRAGE isoforms were measured via ELISAs. After 24 weeks, ADF -6.8 (-9.5, -3.5)kg (Median, IQR) lost more weight than CON -0.3 (-1.9, 1.0)kg (p < 0.05). The change in endogenous secretory RAGE (esRAGE) was different between ADF 15 (-30, 78)pg/mL and CON -21 ( 72, 16)pg/mL after 24 weeks (p < 0.05). To examine the effect of changes in body composition, the cohort was stratified by median weight-, fat-, SAT-, and VAT loss. The changes in all sRAGE isoforms were different between those above and below median weight-loss (p < 0.05) with sRAGE isoforms tending to decrease in individuals below the median. Changes in total sRAGE and esRAGE were different between individuals above compared to below median fat- and SAT-loss (p < 0.05). Those above median fat-loss increased esRAGE by 29 (-5, 66)pg/mL (p < 0.05). CONCLUSION: Improvements in body composition are related to increased sRAGE isoforms, implicating sRAGE as a potential target for the treatment of obesity. CLINICAL TRIAL REGISTRATION: NCT00960505.

AB - Examining feto-maternal blood flow is extremely important for accurate prenatal control and predicting adverse conditions during puerperium. We aimed to analyze blood flow of uterine artery (UA) and umbilical artery (UMA) from and subsequent to mid-gestation, lambing and postpartum of 15 ewes, subjected to lambing induction with aglepristone. Hemodynamic variables, diameter and blood flow of UA and UMA were determined by Doppler and B-mode ultrasonography at 60, 90 and 120 days of pregnancy, at 12 h before, 12 h after first aglepristone injection and 12 h after induction and days 1, 3, 5, 7, 15 and 30 after lambing. The UMA peak systolic:diastolic velocity (S/D), resistance index (RI) and pulsatility index (PI) decreased from mid-pregnancy until 120 d, whereas peak systolic velocity (PSV), end diastolic velocity (EDV) and time average maximum velocity (TAMAX) increased towards 120 d. The UMA RI additionally decreased at 12 h after lambing induction. The UMA diameter and volume increased from mid-gestation until 12 h before lambing induction. UA PSV and TAMAX increased from 60 until 90 days of pregnancy, while EDV, PSV and TAMAX decreased soon after parturition, with a further reduction at 7 days. The UA diameter and volume decreased during postpartum, stabilizing by 15 days after parturition. In conclusion, pregnancy is marked by progressive increase in uterine and umbilical blood flow, while lambing acutely diminishes umbilical vascular resistance, suggesting lack of progesterone influence on vasodilation. Conversely, puerperium is characterized by reduction in uterine blood supply mostly within the first 2 weeks of postpartum in sheep. PMID- 30297204 TI - Supplementation of extender with coenzyme Q10 improves the function and fertility potential of rooster spermatozoa after cryopreservation. AB - The effects of coenzyme Q10 (CoQ10) has not yet been assessed for cryopreservation of rooster semen. The aim of this study was to evaluate the effect of different concentrations of CoQ10 in Lake extender for cryopreservation of rooster semen. The viability and apoptosis status, DNA fragmentation, abnormal morphology, motion parameters, membrane functionality, mitochondrial activity, acrosome integrity, lipid peroxidation, and fertility potential were evaluated after the freeze-thaw process. Semen samples were collected from ten roosters, twice a week, and then diluted in extender contained different concentrations of CoQ10 as follows: Lake without CoQ10 (control, Q 0), Lake containing 1 MUM (Q 1), 2 MUM (Q 2), 5 MUM (Q 5), and 10 MUM (Q 10) CoQ10. Supplementation of Lake with 1 and 2 MUM CoQ10 resulted in greater sperm viability, total motility, progressive motility, membrane functionality, mitochondrial activity, acrosome integrity, and fertility rate. Furthermore, the extent of lipid peroxidation in thawed spermatozoa treated with 1 and 2 MUM CoQ10 was less than with the other groups. Different concentrations of CoQ10 had no effect on DNA fragmentation and sperm morphology. Results of the present study indicate that supplementation of Lake extender with 1 and 2 MUM CoQ10 enhances the quality of rooster sperm after the freeze-thaw process. PMID- 30297205 TI - Outcomes of Chimney Technique for Preservation of the Left Subclavian Artery in Type B Aortic Dissection. AB - OBJECTIVE: To report outcomes of the chimney technique for preservation of the left subclavian artery (LSA) in patients with type B aortic dissection (TBAD). METHODS: A retrospective analysis was performed of a prospectively maintained database from August 2012 to October 2017. Primary endpoints were 30 day and overall mortality. Secondary endpoints were technical success, type Ia endoleak, chimney stent occlusion, aortic rupture, stroke, spinal cord ischaemia, and re intervention rate. RESULTS: A total of 159 patients (mean age 54 +/- 11 years; 141 men) with TBAD were treated using the chimney technique for LSA revascularisation. Acute, subacute, and chronic TBAD accounted for 64%, 28%, and 8% of cases, respectively. One hundred and six cases (67%) were complicated TBAD. One hundred and fifty-six patients (98%) were treated electively, while three (2%) were treated urgently because of intestinal or lower extremity ischaemia. The 30 day mortality and morbidity rates were 2% (3/159) and 4% (7/159), respectively. The technical success rate was 81% (129/159) and immediate type Ia endoleak occurred in 30 (19%) patients. Three major strokes, two spinal cord ischaemia and one aortic rupture, occurred early on. During a mean follow up of 23 +/- 16 months (range 1-65 months), three more patients died: from aortic rupture, cerebral haemorrhage, and rectal cancer, respectively. Chimney stent occlusions were observed in four patients and all these chimney stents were self expanding. During follow up, two major strokes, one late type Ia endoleak and one re-intervention, occurred. According to the Kaplan-Meier curve, the estimated one and three year survival rates were 98.1 +/- 1.1% and 94.4 +/- 2.4%, respectively. CONCLUSION: Short and mid-term outcomes in the present study demonstrate that the chimney technique is safe and feasible for preservation of the LSA in patients with TBAD, but the durability of chimney stent needs to be evaluated carefully and immediate type Ia endoleak is a concern. PMID- 30297206 TI - tsRNAs: The Swiss Army Knife for Translational Regulation. AB - tRNA-derived small RNAs (tsRNAs, or tRFs) are a new category of regulatory noncoding RNAs with versatile functions. Recent emerging studies have begun to unveil distinct features of tsRNAs based on their sequence, RNA modifications, and structures that differentially impact their functions towards regulating multiple aspects of translational control and ribosome biogenesis. PMID- 30297207 TI - 'Nonlinear' Biochemistry of Nucleosome Detergents. AB - The transcriptional activation domains (TADs) are critical for life, yet intrinsically disordered polypeptides with no specific consensus sequence, interacting with multiple targets via low-specificity fuzzy contacts. The recent integration of machine learning approaches in biochemistry allows analysis of large experimental datasets of functional TADs as a whole and clear observation of TAD features. The emerging picture describes TADs as sequences without consensus but with a variety of detergent-like mini-motifs enriched in negatively charged and aromatic amino acids. Comparison of the canonical direct coactivator recruitment model and a new model describing TADs as nucleosome detergents that trigger chromatin remodeling during gene activation helps solve a fundamental enigma of molecular biology spanning 30 years. PMID- 30297208 TI - Long-term effects of unilateral deep brain stimulation on voice tremor in patients with essential tremor. AB - INTRODUCTION: Voice tremor (VT) is a common symptom of Essential tremor (ET). Deep brain stimulation (DBS) is an established treatment for ET overall, however, its effect on VT is less clear. The aim of this study was to evaluate long-term effects of DBS on VT and to investigate how VT symptoms develop over time in patients with ET. METHODS: VT scores for the cohort of 81 ET patients that had undergone DBS surgery in the caudal zona incerta (cZi) were analyzed retrospectively. Thirty-four patients had preoperative VT and long-term evaluations were available for 19 patients. Longitudinal effects of cZi-DBS were investigated 1, 3 and 5 years postoperatively. VT progression was evaluated based on preoperative-, and off stimulation postoperative assessments. RESULTS: Unilateral cZi-DBS reduced average voice tremor by 58% at the 3-year follow-up and by 67% 5 years after surgery. Four patterns of VT development were identified among patients, and the effectiveness of cZi-DBS in alleviating voice tremor symptoms showed differing patterns for these subgroups. CONCLUSIONS: This retrospective analysis of a small cohort of patients suggests that cZi-DBS may reduce VT in the long-term for patients with ET overall, but the pattern of VT progression likely influences the effectiveness of the treatment. These results also suggest that unilateral cZi-DBS may be more efficacious when treating patients with mild to moderate VT. A prospective, blinded, controlled clinical trial in patients with ET is needed to determine developmental patterns of VT, and the safety and efficacy of cZi-DBS for the treatment of VT.

PMID- 30297210 TI - Naftazone in advanced Parkinson's disease: An acute L-DOPA challenge randomized controlled trial. AB - INTRODUCTION: There is an unmet need to better control motor complications in Parkinson's disease (PD). Naftazone, which exhibits glutamate release inhibition properties, has shown antiparkinsonian and antidyskinetic activity in preclinical models of PD and in a clinical proof of concept study. METHODS: We conducted a double-blind randomized placebo-controlled cross-over trial in PD patients with motor fluctuations and dyskinesia testing naftazone 160 mg/day versus placebo for 14 days. The two co-primary endpoints were the area under curve (AUC) of motor (MDS-UPDRS part III) and dyskinesia (AIMS) scores during an acute levodopa challenge performed at the end of each period. Secondary endpoints were UDysRS and axial symptoms scores during the challenge; AIMS, UDysRS, and time spent with or without dyskinesia the day before the challenge. The primary analysis was performed in the per protocol population. RESULTS: Sixteen patients were included in the analysis. There was no difference between naftazone and placebo for the AUC of MDS-UPDRS III (-89, 95%CI[-1071; 893], p = 0.85), and AIMS (70, 95%CI[ 192; 332], p = 0.57). At the end of treatment periods, AIMS score tended to be lower with naftazone than placebo (4.4 +/- 3.4 versus 6.7 +/- 4.4, p = 0.07), but UDysRS scores and other secondary outcomes were not different. Naftazone was safe and well tolerated. CONCLUSIONS: This study did not confirm previous results on the efficacy of naftazone on dyskinesia nor motor fluctuations highlighting the problem of translating results obtained in preclinical models into clinical trials. Further investigation of naftazone may be conducted in PD with longer treatment duration. PMID- 30297211 TI - Predictors of self-perceived stigma in Parkinson's disease. AB - OBJECTIVE: The burden of PD extends beyond physical limitations and includes significant psychosocial adjustments as individuals undergo changes to their self perception and how others perceive them. There is limited quantitative evidence of the factors that contribute to self-perceived stigma, which we addressed in the present study. METHODS: In 362 individuals with PD (157 women, 205 men), self perceived stigma was measured by the four-item stigma subscale of the Parkinson's Disease Questionnaire (PDQ-39). Hierarchical linear modeling was used to assess predictors of stigma including demographics (age, gender) and disease characteristics: duration, stage (Hoehn & Yahr Scale), motor severity (Unified Parkinson's Disease Rating Scale, UPDRS, Part 3), activities of daily living (UPDRS Part 2), and depression (Geriatric Depression Scale). Predictor variables were chosen based on their significant correlations with the stigma subscale. Further analyses were conducted for men and women separately. RESULTS: For the total sample, the full model accounted for 14% of the variance in stigma perception (p < .001). Younger age and higher depression scores were the only significant predictors (both p < .001). This pattern was also seen for the men in the sample. For the women, only depression was a significant predictor. Depression mediated the relation between stigma and activities of daily living. CONCLUSIONS: Younger age (men) and depression (men and women) were the primary predictors of self-perceived stigma in PD. Disease characteristics (motor and ADL) did not contribute to stigma perception. Depression is a potential treatment target for self-perceived stigma in PD. PMID- 30297212 TI - Phosphorylated alpha-synuclein deposits in sural nerve deriving from Schwann cells: A biomarker for Parkinson's disease. AB - INTRODUCTION: Paresthesia is common in Parkinson's disease (PD) patients. We assumed that peripheral nerve might be implicated. This study aimed to investigate whether phosphorylated alpha-synuclein (pSNCA) pathology occurred in sural nerve fibers and to explore the underlying pathogenesis of paresthesia of lower limbs associated with PD. METHODS: Clinical assessments and sural nerve biopsy were performed to evaluate clinical characteristics and the deposition of total alpha-synuclein (tSNCA) and pSNCA in biopsy pieces using immunochemistry methods on 16 PD patients and 15 controls. In addition, immunofluorescence staining was performed using certain antibodies to characterize the component of sural nerve and to localize the expression of pSNCA. RESULTS: Deposition of pSNCA was found in 16/16 PD patients with a high positive percentage of 100% but in 0/15 controls, however, all biopsy pieces showed positive response to tSNCA immunohistological staining in nerve fibers. pSNCA was expressed mainly in Schwann cells but scarcely in axons, demonstrating a novel pattern of pSNCA expression in peripheral nervous system. CONCLUSION: Our findings suggest that peripheral somatic sensory nerve is also involved in SNCA pathology in PD. The search for pSNCA in sural nerve might serve as a novel biomarker for early diagnosis of PD and pSNCA in sural nerve may derive from Schwann cells rather than propagate retrograde along the primary sensory neurons from the central nervous system.

PMID- 30297214 TI - Combined antifungal therapy is superior to monotherapy in pulmonary scedosporiosis in cystic fibrosis. AB - Cystic fibrosis (CF) is characterised by chronic airway infection with bacteria and fungi. Infections caused by Scedosporium/Lomentospora species can occur and are difficult to treat. Moulds belonging to the genus Scedosporium/Lomentospora are detected most frequently in respiratory samples of patients with CF, next to Aspergillus spp. Our aim was to define pulmonary fungal infections due to Scedosporium/Lomentospora in CF and to study the antimycotic treatment. In this multicentre study (12 centres; duration January 2008 to December 2014) 31 patients with a lung infection caused by moulds of the genus Scedosporium/Lomentospora were included. 36 courses of antifungal treatment were documented. Scedosporium apiospermum sensu stricto accounted for 48.4% of cases. In 20/31 patients a therapeutic response under antimycotics (median duration 3.9 months) was achieved. Triple and double therapy was significantly more effective compared to monotherapy regarding FEV1, radiology, and symptoms. This data suggests that combined treatment is superior to monotherapy in patients with CF. PMID- 30297215 TI - How does ballet training alter ankle tendinous morphology and hemodynamics in asymptomatic pre-professional dancers? An ultrasonographic study. AB - OBJECTIVES: Among symptomatic dancers, sonographic abnormalities are common. Whether asymptomatic dancers have any abnormalities remains unknown. Some dancers became cyanosis over distal feet after ballet training. The hemodynamic changes at the feet in ballet are not clearly understood. DESIGN: Cross-sectional study. METHODS: In 25 dancers and 14 non-dancers, B-mode ultrasonography was used to measure cross-sectional areas (CSA) of tendons of deep posterior compartment muscles. Doppler ultrasonography was used to measure peak velocity (Vpeak) of posterior tibial artery in three ankle postures: the neutral position, passively and forced actively plantar flexion (en pointe). The big toe oxygen saturation was recorded in neutral position and during 1-min en pointe. Single-leg standing heel rise test was performed to represent the muscle function. RESULTS: The CSA of FHL was larger in dancers (0.26cm2 [0.20, 0.30] vs 0.21cm2 [0.17, 0.24], p<0.01), while other tendons were not different (all p>0.05). Higher Vpeak was recorded in passively plantar flexion than in neutral position (p<0.01, in both groups). The blood flow was undetectable during en pointe, more frequently in dancers (54.9% vs 14.3%, p<0.01). Oxygen saturation decreased during en pointe more prominently in dancers (85% [80, 90] vs 94% [84, 97], p<0.01). There was no significant difference in muscle function. CONCLUSIONS: US showed the FHL tendon thickening and en pointe-related vascular compromise in pre-professional dancers, even when they are asymptomatic. PMID- 30297216 TI - The effects of recovery duration on physiological and perceptual responses of trained runners during four self-paced HIIT sessions. AB - OBJECTIVES: This study aimed to examine the effects of different recovery durations on self-selected running velocities, physiological responses, and ratings of perceived exertion (RPE) in a commonly used high intensity interval training (HIIT) protocol. DESIGN & METHODS: Twelve trained runners performed an incremental treadmill exercise test to determine maximal oxygen uptake (VO2max) and heart rate (HRmax). In four subsequent visits, participants performed a HIIT session comprising six 4-min work intervals, in which the recovery duration between work intervals equalled either a fixed (1MIN, 2MIN, 3MIN) or a self selected duration (ssMIN). HIIT sessions were run on a non-motorized treadmill, and were performed under isoeffort conditions. RESULTS: Mean running velocity was significantly higher in 3MIN compared with all other protocols, and higher in ssMIN compared with 2MIN. No significant differences in time spent >=90% and 95% VO2max, or >=90% and 95% HRmax were evident between the four protocols. RPE responses were similar across and within the protocols showing a gradual increase with each progressive interval. CONCLUSION: In a self-paced HIIT session of six 4 min work intervals, the length of recovery durations had a limited effect on the total physiological strain endured in the training. However, running velocities were higher when participants received the longest recovery period (3MIN). Longer recovery durations may facilitate a higher external training load (faster running), whilst maintaining a similar internal training load (physiological stimulus), and may therefore allow for greater training adaptations.

Part I: Hard-on-soft bearing pairs. AB - The present study describes the lubrication mechanisms within artificial hip joints considering real conformity of rubbing surfaces. Part I is focused on hard on-soft material combination, introducing the fundamentals of lubrication performance. These pairs have not been explored in terms of in situ observation before. The contact of metal femoral component articulating with transparent polymer acetabular cup was studied using a hip joint simulator. The film formation was evaluated by fluorescent microscopy method. Various model synovial fluids were employed while the key constituents, i.e. albumin, gamma-globulin, and hyaluronic acid were fluorescently stained to determine its role in film formation process. Two types of the tests were performed. The first dynamic test aimed on the development of film thickness under constant load during motor driven swinging motion mimicking flexion-extension. Subsequently, a combined test was designed consisting of the three phases; static part with loading/unloading phase (1), pendulum swinging till spontaneous damping of the motion due to friction (2), and static observation under the constant load (3). The results clearly confirmed that the interaction of constituents of synovial fluid plays a dominant role and substantially influences the lubrication conditions. In particular, the main finding coming from the present study is that gamma-globulin together with hyaluronic acid form relatively thin stable boundary layer enabling the enhanced adsorption of albumin, thus increasing the lubricant film. Part II of the present study is focused on hard-on-hard pairs while the main differences in film formation process are highlighted among others. PMID- 30297221 TI - The Impact of Lymphovascular Invasion on Risk of Upstaging and Lymph Node Metastasis at the Time of Radical Cystectomy. AB - BACKGROUND: Lymphovascular invasion (LVI) in muscle-invasive bladder cancer is associated with a poor prognosis when identified from radical cystectomy (RC) specimens. However, LVI is not clearly emphasized in any risk models to guide clinical decision-making. The impact of LVI on the risk of lymph node (LN) metastasis after a transurethral resection of bladder tumor (TURBT) specimen is less understood. OBJECTIVE: The goal was to describe the impact of LVI and the risk of LN metastasis at each clinical stage of urothelial carcinoma of the bladder (UC). DESIGN, SETTING, AND PARTICIPANTS: The National Cancer Database was queried for patients with bladder cancer who underwent RC with LN dissection from 2004 to 2014. Patients with non-bladder primary, non-UC histology, clinical metastatic disease, and having received chemotherapy/radiation were excluded. Pathologic LN positive rates at RC were determined. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was pathologic upstaging at RC and pathologic node positivity. Secondary outcomes included determining overall survival (OS). All hypotheses testing were two-sided and a p value of <0.05 was considered statistically significant. All statistical analyses were performed using Stata version 13.1. RESULTS AND LIMITATIONS: A total of 3007 patients with UC underwent RC with pelvic LN dissection. In patients with LVI, the risk of LN metastasis was significantly higher at each clinical stage as was the rate of pathologic upstaging. Patients with LVI on TURBT had worse OS stage for stage in pure UC (p<0.001). Limitations include that there was no central pathologic review and the number of TURBTs per patient was not known. CONCLUSIONS: Patients with UC with LVI had worse OS and are at higher risk for LN-positive disease and pathologic upstaging at surgery than patients without LVI. PATIENT SUMMARY: In this report we examined the impact of lymphovascular invasion (LVI) at transurethral resection of bladder tumor on pathologic upstaging and lymph node metastasis at radical cystectomy using the National Cancer Database. We identified LVI as being prognostic at each stage of urothelial carcinoma.

AB - In this study, mono-digestion of the organic fraction of municipal solid waste (OFMSW) and co-digestion of OFMSW with beech sawdust, simulating green waste, were used to investigate the maximum operational total solid (TS) content in semi continuous high-solids anaerobic digestion (HS-AD). To alleviate substrate overloading in HS-AD, the effluent mass was relatively reduced compared to the influent mass, extending the mass retention time. To this aim, the reactor mass was daily evaluated, permitting to assess the reactor content removal by biogas production. During mono-digestion of OFMSW, the NH3 inhibition and the rapid TS removal prevented to maintain HS-AD conditions (i.e. TS >= 10%), without exacerbating the risk of reactor acidification. In contrast, the inclusion of sawdust in OFMSW permitted to operate HS-AD up to 30% TS, before acidification occurred. Therefore, including a lignocellulosic substrate in OFMSW can prevent acidification and stabilize HS-AD at very high TS contents (i.e. 20-30%).

AB - Tree height is one of the most important forest characteristics and is one of the crucial measurements taken for either practical or scientific reasons. However, the accuracy of a tree-height measurement may vary in relation to many factors. The work described here thus sought to evaluate the accuracy of ground-based tree height measurements for major forest-forming tree species of the temperate and boreal zones. The focus was on the importance of factors affecting accuracy of the measurements in question at larger geographical scales. In line with the above research goals, data were gathered from 299 stands throughout Poland and heights of 2388 sample trees of eight species, growing in different stands and site conditions, were measured; heights were then compared with measured lengths of felled trees as a reference. In total, 10 variables to determine factors that may influence ground-based tree-height measurement accuracy were used. We merged them into 4 groups: measurements, topography, stand and biometric-related factors. Results showed that biometric and topographic factors had the greatest relative influence on the accuracy of measurements of tree height. Tree length and species, followed by the slope of the terrain, tree age, and height above sea level were the most important factors found to affect accuracy. In most of the cases studied the terrestrial tree-height measurements were underestimated when set against definitive measurements of length. This was true for all species studied except oak, for which height measurements were typically overestimated. Notwithstanding the broad geographical scope of the work, the particular device used and the team factor were only found to have a marginal influence on measurement accuracy. PMID- 30297225 TI - Gender identity in patients with 5-alpha reductase deficiency raised as females. AB - BACKGROUND AND OBJECTIVE: 5-Alpha reductase type 2 deficiency (5-ARD) is a rare disorder of sex development. The lack of 5-alpha reductase, an enzyme that converts testosterone into dihydrotestosterone, results in external genitalia that may appear female, or predominantly male, albeit undervirilized, or, more often, ambiguous. METHODS: This study describes a series of patients with 5-ARD raised as female, focusing on aspects related to gender identity. Following a retrospective chart review, patients with 5-ARD were invited to return to the clinic to enable their gender identity to be assessed using an 11-item structured in-house questionnaire. The Golombok-Rust Inventory of Sexual Satisfaction was applied to patients who had initiated their sexual life. RESULTS: Six patients aged >15 years with 5-ARD and raised as female were included. Most patients were diagnosed late: two before and four after puberty. The mean length of the phallus was 2.8 cm (0.5-5.0). Reasons for seeing a doctor included genital appearance (n = 3), amenorrhea/absence of breast development (n = 2), and changes in gender role attitudes (n = 1). According to the gender identity assessment, 4 patients identified as female, 1 as male, and 1 as both genders. Only the patient identified as male requested gender re-assignment. Of the two patients who had initiated their sexual life, sexual satisfaction was found to be good in one and poor in the other due to vaginal discomfort during intercourse. CONCLUSION: In the present series, the majority of undervirilized patients with a diagnosis of 5 ARD raised as female were in complete conformation with being female and described themselves as heterosexual. The more virilized patients were those least in conformity with their female-assigned gender. PMID- 30297226 TI - Assessment of pediatric bowel and bladder dysfunction: a critical appraisal of the literature. AB - OBJECTIVE: Bowel and bladder dysfunction (BBD) is a clinical syndrome defined by the coexistence of constipation and lower urinary tract symptoms. Although BBD is a common condition in pediatric urology and can cause significant stress to patients/parents, clinical diagnosis of BBD has not been standardized. Bowel and bladder dysfunction instruments have gained popularity over the past decade to aid in diagnosis. In this review, the currently published BBD symptom questionnaires were summarized and an analysis on their psychometric validation process was provided. SUBJECTS/PATIENTS: PubMed was searched for articles on BBD symptom questionnaires/instruments/surveys since 2000. Two investigators (R.Y.J. & M.S.K.) conducted the search in duplicate. The search was limited to English language. The included search terms were 'dysfunctional elimination syndrome', 'bowel and bladder dysfunction', 'dysfunctional voiding', 'voiding dysfunction symptom score', and 'dysfunctional voiding symptom scale'. Reference lists of included studies were screened for missed studies. Unpublished abstracts presented at the following scientific meetings were also manually searched for: the American Urological Association, the Society for Pediatric Urology, and the American Academy of Pediatrics Section on Urology. Exclusion criteria included articles in languages other than English, articles not related to BBD questionnaires, and articles not pertaining to pediatric patients. RESULTS: After initial search, a total of 54 articles were obtained. Of the seven questionnaires reviewed, only one did not measure sensitivity or specificity. Almost all questionnaires showed excellent discriminative property with an Area under the curve (AUC) >0.85. Criterion validity was not reported in any of the questionnaires. Known-group validation was used as a common method to evaluate construct validity. Internal consistency was reported in 2 studies, and only 1 study measured questionnaire responsiveness during initial validation. CONCLUSIONS: Although BBD is a common pediatric urology condition; a large amount of heterogeneity exists in the questionnaires' psychometric testing and validation process. To further improve the diagnosis and management of BBD in pediatric patients, there is a need for consensus on the gold standard questionnaire measure. PMID- 30297227 TI - How to apply for a research grant: 10 tips and tricks. PMID- 30297228 TI - Perineal hypospadias: back to the future Chordee Excision & Distal Urethroplasty. AB - PURPOSE: Perineal hypospadias correction has swung from two-stage repair in the 1960s to one-stage repair in the 1980s and back to two-stage repair in the 2000s. The author's experience with a technique in which Chordee Excision and Distal Urethroplasty (CEDU) was performed at the first operation leaving a 1-cm segment as perineal urethrotomy to be reconstructed at the second operation is presented. PATIENTS AND METHODS: Between January 2013 and December 2016, the CEDU technique was performed in 63 patients with perineal hypospadias. The records of 59 patients who maintained regular follow-up were reviewed. The principle is to excise the hypoplastic urethral plate, atretic corpus spongiosum, and longitudinal layer of tunica albuginea; split the glans in the midline; and reconstruct a healthy urethral plate using preputial and lateral skin flaps to the tip of the glans. Distal urethroplasty was performed leaving 1 cm at the proximal end to be reconstructed 3-6 months later. This principle was used by Duplay in the 1880s. Patient age ranged between 6 months and 2 years (mean 8 months). All the patients had perineal hypospadias and bifid scrotum with severe deep chordee. Follow-up period ranged from 17 to 53 months (mean 36). A transurethral Silastic catheter was inserted for 4 days. Three months later, the remaining 1 cm of the new urethra was reconstructed, and final adjustment of the glans and foreskin was performed. RESULTS: Satisfactory results were obtained in 54 patients (90%). Three children experienced glans dehiscence that was corrected in the second stage, one child developed fistula after the second operation, and one developed diverticulum. The fistula and diverticulum were corrected at the third operation successfully. DISCUSSION: It was necessary in this series to divide the urethral plate and excise the hypoplastic corpus spongiosum and the outer longitudinal layer of tunica albuginea to correct the associated deep chordee. The lateral skin flaps receive double blood supply from the base of the penis and the preputial vessels. This natural urinary diversion allows early removal of the catheter, reduces the discomfort of the patient, and allows the new urethra to heal without urine irritation for 3 months. Long-term follow-up for 15 years is necessary to assess the technique objectively. CONCLUSIONS: The CEDU technique diverts urine away from the site of urethroplasty for 3 months without a catheter. It reduces the hospital stay and patient discomfort. It produces satisfactory results and has become a the standard technique in perineal hypospadias.

AB - BACKGROUND: Adults with physical disabilities typically engage in low levels of physical activity (PA), thus a better understanding of how motivational factors and behavior vary over time and in relation to disability type and severity is needed. OBJECTIVE/HYPOTHESIS: To examine temporal changes in theory of planned behavior (TPB) constructs and PA by disability type (multiple sclerosis vs. spinal cord injury) and severity (mild, moderate, and severe). METHODS: Participants were 77 adults with physical disabilities who completed a web-based survey that assessed the TPB constructs and PA participation. The survey was completed once every four months for a total of three time points. Two-way repeated measures ANOVAs were used to examine if the TPB constructs and PA changed over time and in relation to disability type and severity. RESULTS: There was only one significant between-subjects effect for PA by disability severity, F (2, 68) = 5.94, p = .004, eta2 = 15%. People with mild disabilities exhibited higher mean PA participation over the three time periods (M = 21.06 +/- 11.49 MET hrs/day) than those with moderate disabilities (M = 11.27 +/- 9.3 MET-hrs/day) and severe disabilities (M = 13.43 +/- 14.74 MET-hrs/day). CONCLUSIONS: Although participants possessed positive PA motivational factors that remained stable over time, their PA participation was low and differed as a function of disability severity. Therefore, PA interventions should be tailored such that individuals with severe disabilities receive the greatest amount of exercise prescription consultations and supervision compared to those with more moderate and mild disabilities. PMID- 30297231 TI - Primary versus secondary intraocular lens implantation in traumatic cataract after open-globe injury in pediatric patients. AB - PURPOSE: To compare the visual and refractive outcomes and complications of primary and secondary intraocular lens (IOL) implantation after open-globe injury in pediatric patients. SETTING: Sadguru Netra Chikitsalaya, Madhya Pradesh, India. DESIGN: Retrospective case series. METHODS: Patients had primary cataract extraction with IOL implantation with globe repair (Group A) or repair followed by secondary IOL implantation (Group B). Preoperative and surgery data, visual outcomes, and postoperative complications were recorded. RESULTS: The study included 139 patients. Thirty (49%) of 61 patients in Group A and 47 (60%) of 78 patients in Group B achieved a corrected distance visual acuity (CDVA) of 20/40 or better. In both groups, a central corneal scar and amblyopia were the main reasons for not achieving a CDVA better than 20/40. The mean spherical equivalent (SE) was 1.81 diopters (D) in Group A and 1.55 D in Group B. Forty patients (66%) in Group A and in 60 patients (77%) in Group B achieved a desirable refractive outcome (SE <2.00 D). A large wound was the greatest risk factor for not obtaining desirable refractive outcomes. Fibrinous uveitis was the most common postoperative complication in both groups. Pupillary optic capture and IOL decentration were significantly more common in Group A than in Group B (P = .02), while strabismus was significantly more common in Group B (P = .04). CONCLUSIONS: Both approaches had satisfactory and comparable visual and refractive outcomes. However, primary IOL implantation can be considered in cases with small peripheral corneal lacerations with the goal of providing early visual rehabilitation and avoiding repeat general anesthesia. PMID- 30297232 TI - Femtosecond-assisted LASIK flaps resistant to lift secondary to corneal epithelial defects: Case reports and ex vivo studies. AB - PURPOSE: To evaluate why epithelial defects created before femtosecond laser ablation result in laser in situ keratomileusis (LASIK) flaps resistant to lift. SETTING: Boston Eye Group, Brookline, Massachusetts, USA. DESIGN: Case reports and ex vivo studies. METHODS: To examine the mechanism of resistance to flap lift after epithelial defects, flap creation with a femtosecond laser was performed in 30 fresh porcine eyes. Before ablation, the eyes were assigned to 3 groups. Group 1 was a control group with intact corneal epithelium. In Group 2, a central 2.0 mm corneal epithelial defect was created by marking it with a 2.0 mm trephine. In Group 3, a peripheral 2.0 mm epithelial defect was created similarly. After the femtosecond laser procedure was performed, the flaps were lifted and the resistance to lift was documented. The corneas were further examined using anterior segment optical coherence tomography. RESULTS: In Group 1, no resistance was felt during flap lifts. In Group 2, significant resistance was encountered at the edge of the epithelial defects and the flaps could not be lifted in 7 of 10 eyes. In Group 3, similar significant resistance was encountered in all 10 eyes. Six of 10 flaps could not be lifted. Anterior segment optical coherence tomography from a representative cornea from Group 2 demonstrated a deeper dissection plane in the area where the overlying epithelium was missing. CONCLUSION: Epithelial defects can interfere with proper LASIK flap creation with the femtosecond laser. This seems to be attributable to a deeper cutting plane under the area of the epithelial defects compared with the surrounding area with intact epithelium. PMID- 30297233 TI - Separation performance of a star-shaped truxene-based stationary phase functionalized with peripheral 3,4-ethylenedioxythiophene moieties for capillary gas chromatography. AB - This work describes the separation performance of a star-shaped truxene-based material (denoted as EDOTT) as the stationary phase for capillary gas chromatography (GC). The EDOTT capillary column achieved the column efficiency of 5920 plates/m by n-dodecane, 4890 plates/m by naphthalene and 3960 plates/m by 1 octanol at 120 C. Its selectivity and retention behaviour were investigated by a number of mixtures of diverse analytes and their isomers. As a result, it showed advantageous performance for separations of apolar to polar analytes, especially phenols and alcohols, over its analogous TTT, TDT and TFT stationary phases. In addition, the EDOTT capillary column was investigated for its column loadability, repeatability and thermal stability, and was finally applied for the determination of isomer impurities in real samples. This work provides an alternative truxene-based stationary phase with high selectivity for polar analytes and demonstrates the key role of structural modification in developing a family of stationary phases with specific selectivity for targeted analytes. PMID- 30297235 TI - Accurate quantification of beta-hexosaminidase released from laboratory of allergic diseases 2 cells via liquid chromatography tandem mass spectrometry method. AB - beta-Hexosaminidase is one of the enzymes that is secreted from mast cells via antigen-induced degranulation and has frequently been used as an indicator of anaphylactic reactions. The main method for determining beta-hexosaminidase is indirect, "substrate-based" and shows limitations. Hence, development of an accurate detecting method is particularly important and urgently needed. In this study we developed a liquid chromatography tandem mass spectrometry (LC-MS/MS) method for measuring beta-hexosaminidase. Laboratory of allergic diseases 2 (LAD2) cells were stimulated with compound 48/80 (C48/80), the supernatant was collected and subjected to in-solution protein digestion; the obtained peptides were desalted, concentrated, separated and analyzed with an LC-tandem MS instrument. A peptide with the sequence "LAPGTIVEVWK" was selected for quantitative analysis, and four other peptides for qualitative research. The time effect relationship curve was studied, and the results of the LC-MS/MS method were found to be almost consistent with those obtained via the conventional method. The method was then employed to measure beta-hexosaminidase released from LAD2 cells stimulated with potential allergens, and the results showed that it can be applied to determine the potential allergenicity of drugs. This new method showed good specificity, high sensitivity and a wide application range. It could be used to evaluate allergic reactions, providing a guide for medication safety during clinical testing. PMID- 30297234 TI - Aqueous extraction followed by derivatization and liquid chromatography-mass spectrometry analysis: A unique strategy for trace detection and identification of G-nerve agents in environmental matrices. AB - A highly sensitive method for the detection and identification of sarin (GB), soman (GD) and cyclosarin (GF) chemical warfare agents (CWAs) in environmental outdoor and indoor matrices such as soil, asphalt, linoleum, formica, concrete and cloth was developed. The method incorporates derivatization of the G-type nerve agent extracts with 2-[(dimethylamino)methyl]phenol (2-DMAMP), followed by LC-ESI(+)-MS/MS analysis. Four LC-amenable extraction solvents were explored in terms of their extraction efficiency and the reaction rate of the derivatizing agent. The reaction time, temperature and derivatization reagent amount were optimized. The optimal procedure was found to be extraction with water by agitation (2 min), followed by the addition of 2-DMAMP directly into the injection vial and stirring for 5 min prior to LC-ESI(+)-MS/MS analysis, without any other pretreatment. The method was applied to real-world samples and exhibited very low detection limits (LODs) of 0.8-20 pg/cm2 in asphalt, linoleum, cloth, formica and concrete and 4 pg/g in soil. The newly developed method demonstrated significantly superior sensitivity compared to conventional GC-MS- and LC-MS-based methods for the identification of G-nerve agents and allowed the determination of both G-nerve agents and their hydrolysis products within a single LC-MS/MS run. The proposed methodology may be practical for verifying contaminated matrices collected in the battlefield or terror scenes in forensic investigations where trace level analysis is required. PMID- 30297236 TI - Chromatography of mono- and disaccharides on granulated pellets of hydrophobic zeolites. AB - The chromatographic response of sugars at granulated zeolite pellets in preparative scale liquid chromatography is analyzed with respect to the distribution equilibrium and mass transfer. In contrast to hydrophilic FAU type zeolites their hydrophobic dealuminated counterpart, used here, can separate disaccharides the retention of which can strongly exceed those of the monosugars. The retention is correlated with data of batch adsorption studies from the literature. Whereas the retention decreases with increasing temperature, the peak sharpness shows the opposite trend. The effective mass resistance is calculated for a series of mono- and disaccharides. It increases with the capacity factor. The diffusion coefficient of the trehalulose disaccharide is restricted by a factor of about 2 in the macropores and by a factor of more than 104 in the micropores. PMID- 30297237 TI - [Dermatofibrosarcoma: Management]. AB - Dematofibrosarcoma protuberans (DFSP) are very rare (1 to 4 incident cases per million of inhabitants). The local spreading of DFSP is underestimated. The histological diagnosis is challenging but we now know a specific marker (translocation t(17;22)(q22;q13) (COL1A1;PDGFB)). The risk of metastatic relapse is low (and related to fibrosarcoma component); the risk of local relapse depends on the quality of surgery. Management of localized DFSP is based on large resection with meticulous analysis of margins (with or without Mohs microsurgery). Advanced stages not amenable to surgery or metastatic DFSP (with presence of COL1A1;PDGFB) are best treated with imatinib. Locally advanced DFSP potentially amenable to curative intent surgery could be treated with imatinib as neo-adjuvant treatment. The management of these tumours requires multidisciplinary expertise.

PMID- 30297240 TI - Obstruction predicts worse long-term outcomes in stage III colon cancer: A secondary analysis of the N0147 trial. AB - BACKGROUND: Patients with colon cancer often present with obstruction. Large series have reported obstruction among the high-risk features, yet prospective data on its specific prognostic influence are lacking. We hypothesized that obstruction is an independent risk factor for poor prognosis in patients with stage III colon cancer. METHODS: N0147 was a trial conducted between 2004 and 2009 that randomly assigned patients with stage III colon cancer to adjuvant regimens of folinic acid (leucovorin calcium), fluorouracil, and oxaliplatin or fluorouracil, leucovorin, and irinotecan, with or without cetuximab. Patient level data from the control chemotherapy-only arms were obtained. Patient, tumor, and treatment characteristics were abstracted. Disease-free survival and overall survival were estimated by the Kaplan-Meier method. Proportions were compared by chi2 and Fisher exact tests. Univariable and multivariable survival analyses were performed using Cox proportional hazards models. RESULTS: Of 1,543 patients with stage III colon cancer, 250 (16.2%) presented with obstruction. Patients with obstruction were equally likely to complete 12 cycles of adjuvant chemotherapy (75.9% vs 77.1%, P = .6). With median follow-up time of 30.9 months among survivors, five-year overall survival and disease-free survival were worse among patients with obstruction (overall survival 67.7% vs 78.0%, P < .001; disease free survival 53.9% vs 67.0%, P < .0001). On multivariable analysis, obstruction remained significantly associated with worse survival after adjusting for T stage, N stage, performance status, age, sex, histologic grade, and body mass index (overall survival hazard ratio 1.57, 95% confidence interval 1.12-2.20, P = .001; disease-free survival 1.52, 95% confidence interval 1.18-1.95, P < .001). CONCLUSION: In this prospectively followed cohort of patients with stage III colon cancer treated with adjuvant chemotherapy, obstruction was associated with recurrence and worse survival. Moreover, this effect was independent of T and N stage and histologic grade. These results suggest that obstruction should be incorporated into novel risk-stratification models. PMID- 30297241 TI - Influence of lung donor agonal and warm ischemic times on early mortality: Analyses from the ISHLT DCD Lung Transplant Registry. AB - BACKGROUND: In this study we aimed to assess the impact of agonal time and warm ischemic time on early survival in Category III donation-after-circulatory-death (DCD) donor lung transplants (LTxs) using data reported to the International Society for Heart and Lung Transplantation (ISHLT) DCD Lung Transplant Registry. METHODS: In this retrospective study, data were analyzed for 507 DCD LTxs done between January 2005 and June 2015. DCD lung donor agonal time (defined as withdrawal of life support to cessation of cardiac output) and warm ischemic time (WIT; defined as donor systolic blood pressure <50mm Hg to cold pulmonary artery flush) were divided into 3 clinical timing categories (<30 minutes, 30 to 60 minutes, >60 minutes) and 3 tertiles. Univariate analysis was undertaken for all categorizations, and Day 30/Day 365 Kaplan-Meier survival rates were calculated and compared. Multivariable analysis included Cox proportional hazards regression models to estimate hazard of 365-day mortality. RESULTS: Four hundred sixty-five and 301 DCD LTxs had data to analyze in the agonal and warm ischemic time groups, respectively. Day 30 and Day 365 post-transplant survival overall were 96% and 90%, respectively, and not statistically different according to agonal or WIT category or tertile. CONCLUSIONS: Current experience with DCD Category III LTx does not show a relationship between the duration of donor agonal phase or warm ischemic time up to 60 minutes and early survival. These results suggest the true limits of clinical DCD allograft warm ischemic times may not yet be reached. Global variations in clinical DCD practice are apparent. Continued accurate recording and analyses of DCD processes is warranted. PMID- 30297242 TI - Immunotherapy is Here to Stay: A New Treatment Paradigm in Lung Cancer.

Here, we highlight studies of evolutionary ecology in urban environments to argue that cities provide ideal conditions that can be leveraged to study the speciation process. Considering general findings from these studies, we discuss the mechanisms of speciation that are likely to occur in cities. We also discuss fundamental questions about speciation that urban environments are uniquely suited to address, such as those about the earliest stages of divergence or the role of phenotypic plasticity. We conclude that the study of contemporary speciation in urban environments has promise to facilitate discoveries about the process of speciation as it occurs in the Anthropocene. PMID- 30297246 TI - Electronic Patient-Reported Outcomes: Semi-Automated Data Collection in the Interventional Radiology Clinic. AB - INTRODUCTION: Patient-reported outcomes are important for clinical research and will likely be used in the near future as a metric for physician reimbursement. This study aims to evaluate the implementation of an electronic data collection system for deep vein thrombosis and lymphedema quality-of-life (QOL) questionnaires in a tertiary care interventional radiology practice. METHODS: A single provider's clinic patients were automatically e-mailed validated questionnaires 1 week before their appointments. If not completed via e-mail, the questionnaire was administered on an electronic tablet in clinic by a research coordinator. Patients were also sent postprocedure questionnaires. RESULTS: In all, 106 patients visited the clinic for a pre-intervention venous consultation. Of them, 96% (n = 102 of 106) completed the pre-intervention questionnaire: 48% (n = 47 of 98) via e-mail and 52% (n = 51 of 98) via tablet. Of the patients who had procedures and were sent questionnaires, 49% (n = 26 of 53) were seen in person. Of the postprocedure in-person clinic patients, 76% (n = 20 of 26) completed the questionnaire via e-mail, and the remainder with the tablet in clinic. Twenty-seven of the 53 (51%) patients did not return for follow-up and instead were sent an electronic questionnaire as their only source of follow-up, of which 74% (n = 20 of 27) complied. CONCLUSION: After an initial introduction to electronic QOL reporting, patients were more likely to complete the questionnaires remotely for their follow-up appointment. A semi-automated electronic QOL system allows physicians to collect patient outcome data even in the absence of a clinic visit.

AB - The purpose of this study is to determine the relationship between heat stroke and ischemic heart disease (IHD), in a nationwide population using a longitudinal approach. We retrospectively examined the data from the National Health Insurance Research Database (NHIRD) in Taiwan, for patients examined between 2000 and 2013. In total, 628 patients with a heat stroke episode were enrolled and matched with 1256 patients without any history of a heat stroke episode by propensity score matching at a ratio of 1:2. The mean follow-up years of the heat stroke group was 11.89 years and the mean follow up of the control group was 11.51 years. An association between heat stroke episodes and IHD (log-rank p < .001) was found in a univariate cox regression analysis. After multivariate adjustment, age, comorbidities (hypertension, diabetes, stroke), and lower insurance premiums were associated with IHD events in patients who had a heat stroke. IHD was independently associated with heat stroke following cox multivariate regression analysis and patients with a heat stroke episode had a higher incidence of IHD events compared to those without any heat stroke episode (2598.41/105 person years vs. 1286.14/105 person-years, adjusted hazard ratio 3.527, 95% CI: 2.078 4.032, p < .001). The onset of IHD in patients who suffered a heat stroke was earlier than in those without a heat stroke episode (2.08 +/- 3.45 vs. 3.61 +/- 3.25 years, p < .001). In conclusion, clinicians should be aware about evaluating the IHD risk following a heat stroke episode in a patient.

PMID- 30297252 TI - Analysis of predictive response scores to treatment with ursodeoxycholic acid in patients with primary biliary cholangitis. AB - BACKGROUND AND OBJECTIVES: Primary biliary cholangitis (PBC) is an autoimmune disease that affects the small bile ducts. The only treatments currently approved in our country are ursodeoxycholic acid (UDCA) and obeticholic acid. Different indices evaluate the response after one year of treatment. The aim of our study was to evaluate the different predictive scores and prognostic factors of response to UDCA. MATERIAL AND METHODS: Retrospective single-centre study in which clinical and analytical data of patients diagnosed with PBC were collected from January 1987 to December 2015. The response after one year of treatment was evaluated using the different response scores and their concordance degree using the Kappa index. The area under the receiver operating characteristic curve (AUROC) was calculated to determine the predictive capacity of the scores. Likewise, the prognostic factors of response to treatment were analysed. RESULTS: We included 153 patients. The bivariate analysis showed a statistically significant relationship between the initial high levels of alkaline phosphatase and cholesterol and the poor response to treatment. The best AUROC was in Paris-I score (0.81). The concordance between the different scores was low. The GLOBE score was valid to evaluate the prognosis. CONCLUSION: Basal alkaline phosphatase and cholesterol were predictors of poor outcome. The best predictive qualitative score in our cohort patients was Paris-I. There was a poor concordance between the different predictive scores. GLOBE score is valid to evaluate prognosis.

AB - BACKGROUND AND OBJECTIVES: The aims of the study were to analyse the epidemiology, prognostic and predictive factors of malignant disease on isolated involuntary weight loss (IIWL) and to know the effectiveness of the quick diagnosis unit in the evaluation of the process. MATERIAL AND METHODS: Prospective observational study realised from 2006 to 2015 of all patients who were evaluated with IIWL in the quick diagnosis unit. Demographic, clinical, diagnostic and evolutive variables were analysed. Through the analysis of logistic regression, predictive factors of malignant disease and prognostic factors were identified. RESULTS: Of the 533 registered patients, 55.1% were>=65 years old. The diagnostics were: non-neoplastic organic disorders in 214 patients (40.2%), psychiatric disorders in 144 (27%), cancer in 81 (15.2%) and unknown cause in 94 (17.6%). In 66.7% of the patients with cancer, there was an increase of serum tumour markers (STM). Being over 60 (OR: 2.57; 95% CI: 1.27-5.77; P=.01) %), male (OR: 3.23; 95% CI: 1.52-6.87; P=0.002), increase of an STM (OR: 2.38; 95% CI: 1.17-4.8; P=0.016) and more than one STM (OR: 6.51; 95% CI: 2.62-16.13; P=0.000) were identified as predictive factors of malignancy. Mortality was 14.2%; the diagnosis of cancer (OR: 47.61; 95% CI: 20.76-109.19; P=0.000) was identified as a prognostic factor. CONCLUSIONS: IIWL is a clinical syndrome that requires a study with a sequential protocol and follow-up. STM were identified as predictive factors of malignancy.

PMID- 30297256 TI - New Insights Into the Use of Cardiac Magnetic Resonance Imaging to Guide Decision Making in Atrial Fibrillation Management. AB - Recent advances in cardiac magnetic resonance (CMR) imaging acquisition techniques have enabled the visualization of thin atrial myocardium with high temporal and spatial resolution and have the potential to shift atrial fibrillation (AF) management paradigms. Late gadolinium-enhancement (LGE)-CMR can noninvasively identify atrial arrhythmogenic scar substrates and has been shown to spatially correlate with low-voltage areas. Immediately after ablation, a combination of native T1-weighted, LGE, and T2-weighted imaging can assess ablation lesions and localize reversible edema, whereas late after ablation, LGE CMR can visualize irreversible fibrosis and detect large ablation gaps. Tissue tracking on cine-CMR can be used to characterize the impact of ablation and AF related remodelling on atrial structure and contractile function. Increased burden of "native" LGE and lower left atrial function at baseline are associated with worse procedural outcomes, and identification of patients with the greatest fibrotic extent may improve patient selection for AF ablation procedures or identify a subset of patients for whom pulmonary vein isolation alone is unlikely to be beneficial. Left atrial appendage morphology and left atrial sphericity index may provide additional prognostic information in AF ablations. A suggested approach for patients with extensive fibrosis includes substrate modification in addition to pulmonary vein isolation. Another approach involves virtual electrophysiological simulation of AF, localization of computationally derived AF drivers, and determination of optimal ablation targets for persistent AF suppression. Finally, both LGE-CMR and cine-CMR have offered invaluable insights into AF-related stroke mechanisms and may enhance available prediction models that guide anticoagulation therapy.

AB - BACKGROUND: Metal metaphyseal sleeves are an option for reconstruction as well as enhancing fixation in managing challenging bone defects in revision knee replacement. We report our results of revision knee replacement using metaphyseal sleeves with a minimum of seven years of follow-up. METHODS: The records of 103 patients (104 knees) who underwent revision knee replacement using metaphyseal sleeves in our centre were evaluated. The follow-up included clinical assessment, functional scores and radiologic assessment. RESULTS: The mean age of patients was 74.7 (tange 58-92) years. Mean follow-up was 95.7 (range, 88-115) months. From the original cohort, 15 (14%) patients had died from unrelated causes. During the follow-up period, there were 23 (22.1%) re-revisions. Indications for re-revision was aseptic loosening in seven (6.7%), stiffness in four (3.8%), infection in five (4.8%), instability in three (2.8%) and persistent pain in two (1.9%) patients. For aseptic loosening, the average time for re-revisions was 56.6 months (range 25 to 84). Radiographically, all unrevised sleeves were well fixed, without any evidence of loosening. Oxford knee score in patients without re-revisions was 28.5 (range four to 48). CONCLUSION: At mid-term follow-up, metaphyseal sleeves demonstrate durable clinical results and radiographic fixation. PMID- 30297258 TI - Estimation of non-shivering thermogenesis and cold-induced nutrient oxidation rates: Impact of method for data selection and analysis. AB - BACKGROUND & AIMS: Since the discovery of active brown adipose tissue in human adults, non-shivering cold-induced thermogenesis (CIT) has been regarded as a promising tool to combat obesity. However, there is a lack of consensus regarding the method of choice to analyze indirect calorimetry data from a CIT study. We analyzed the impact of methods for data selection and methods for data analysis on measures of cold-induced energy expenditure (EE) and nutrient oxidation rates. METHODS: Forty-four young healthy adults (22.1 +/- 2.1 years old, 25.6 +/- 5.2 kg/m2, 29 women) participated in the study. Resting metabolic rate (RMR), cold induced thermogenesis (CIT), and cold-induced nutrient oxidation rates were estimated by indirect calorimetry under fasting conditions during 1 h of cold exposure combining air conditioning (19.5-20 degrees C) and a water perfused cooling vest set at a temperature of 4 degrees C above the individual shivering threshold. We applied three methods for data selection: (i) time intervals every 5 min (5min-TI), (ii) the most stable 5-min period of every forth part of the cold exposure (5min-SS-4P), and (iii) the most stable 5-min period of every half part of the cold exposure (5min-SS-2P). Lately we applied two methods for data analysis: (i) area under the curve as a percentage of the baseline RMR (AUC) and; (ii) the difference between EE at the end of the cold exposure and baseline RMR (Last-RMR). RESULTS: Mean overall CIT estimation ranged from 11.6 +/- 10.0 to 20.1 +/- 17.2 %RMR depending on the methods for data selection and analysis used. Regarding methods for data selection, 5min-SS-2P did not allow to observe physiologically relevant phenomena (e.g. metabolic shift in fuel oxidation; P = 0.547) due to a lack of resolution. The 5min-TI and 5min-SS-4P methods for data selection seemed to be accurate enough to observe physiologically relevant phenomena (all P < 0.014), but not comparable for estimating over-all CIT and cold-induced nutrient oxidation rates (P < 0.01). Regarding methods for data analysis, the AUC seemed to be less affected for data artefacts and to be more representative in participants with a non-stable energy expenditure during cold exposure. CONCLUSIONS: The methods for data selection and analysis can have a profound impact on CIT and cold-induced nutrient oxidation rates estimations, and therefore, it is mandatory to unify it across scientific community to allow inter study comparisons. Based on our findings, 5min-TI should be considered the method of choice to study dynamics (i.e. changes across time) of CIT and cold-induced nutrient oxidation rates, while 5min-SS-4P and AUC should be the method of choice when computing CIT and cold-induced nutrient oxidation rates as a single value.

AB - INTRODUCTION: Due to the growing shortage of general practitioners (GPs), solutions are being sought to improve the structure and attraction of specialist training in general practice. In 2012, the Competence Center for Specialist Training in General Practice was set up in the federal state of Hesse, Germany, in order to provide a seminar- and mentoring program to complement standard specialist training. The present paper examines whether the mentoring program, which was based on needs assessment, supports doctors in training (DiT) to become specialists in general practice. METHODS: A mixed-methods design was used for the evaluation of the mentoring program. The pilot cohort monitored in this study was surveyed using a guideline-based interview. The cohort consisted of the first cohort of participants in the Specialist Training Academy (n=21), which was divided into two mentoring groups. Responses were evaluated with the help of the MAXQDA 11 program and qualitative content analysis to structure content. Furthermore, all 16 group meetings were assessed by means of evaluation sheets (n=132) and analyzed descriptively using the statistics program SPSS (IBM statistics, Version 20). RESULTS: Of the 21 DiTs of the total sample that took part in the interviews, two-thirds of the surveyed mentees were female (71.4 %). The mentoring and seminar programs encouraged the mentees in their decision for and their identification with specialist training in general practice and helped them overcome any doubts about their choice. The decisive factors in the mentoring process were interacting with like-minded people, discussing organizational questions and having a fixed contact person in case of questions and doubts. The evaluation sheets made it clear that the mentees regarded the mentoring as supportive (99.3 % positive). Compared to the other mentoring group, participants in the one group felt they were better supported by mentoring, found the interaction with other DiTs more helpful, the interaction between mentors and the group exactly right, and the topics they discussed more relevant. CONCLUSION: The provided mentoring program fulfilled the expectations of the DiTs in general practice. Combined with the Specialist Training Academy's seminar program, the two programs complement each other and are an important step towards making specialist training in general practice more attractive.

PMID- 30297264 TI - Factors Affecting Oncologic Outcomes of 90Y Radioembolization of Heavily Pre Treated Patients With Colon Cancer Liver Metastases. AB - INTRODUCTION: The purpose of this study was to identify predictors of overall (OS) and liver progression-free survival (LPFS) following Yttrium-90 radioembolization (RAE) of heavily pretreated patients with colorectal cancer liver metastases (CLM), as well as to create and validate a predictive nomogram for OS. MATERIALS AND METHODS: Metabolic, anatomic, laboratory, pathologic, genetic, primary disease, and procedure-related factors, as well as pre- and post RAE therapies in 103 patients with CLM treated with RAE from September 15, 2009 to March 21, 2017 were analyzed. LPFS was defined by Response Evaluation Criteria In Solid Tumors 1.1 and European Organization for Research and Treatment of Cancer criteria. Prognosticators of OS and LPFS were selected using univariate Cox regression, adjusted for clustering and competing risk analysis (for LPFS), and subsequently tested in multivariate analysis (MVA). The nomogram was built using R statistical software and internally validated using bootstrap resampling. RESULTS: Patients received RAE at a median of 30.9 months (range, 3.4-161.7 months) after detection of CLM. The median OS and LPFS were 11.3 months (95% confidence interval, 7.9-15.1 months) and 4 months (95% confidence interval, 3.3 4.8 months), respectively. Of the 40 parameters tested, 6 were independently associated with OS in MVA. These baseline parameters included number of extrahepatic disease sites (P < .001), carcinoembryonic antigen (P < .001), albumin (P = .005), alanine aminotransferase level (P < .001), tumor differentiation level (P < .001), and the sum of the 2 largest tumor diameters (P < .001). The 1-year OS of patients with total points of < 25 versus > 80 was 90% and 10%, respectively. Bootstrap resampling showed good discrimination (optimism corrected c-index = 0.745) and calibration (mean absolute prediction error = 0.299) of the nomogram. Only baseline maximum standardized uptake value was significant in MVA for LPFS prediction (P < .001; SHR = 1.06). CONCLUSION: The developed nomogram included 6 pre-RAE parameters and provided good prediction of survival post-RAE in heavily pretreated patients. Baseline maximum standardized uptake value was the single significant predictor of LPFS. PMID- 30297263 TI - Effects of Adjuvant Chemotherapy on Cognitive Function of Patients With Early stage Colorectal Cancer. AB - PURPOSE: Chemotherapy-related cognitive impairment can occur in cancer survivors after treatment, especially those patients who have undergone chemotherapy for breast cancer. The frequency and to what extent such toxicity develops in colorectal cancer (CRC) survivors is unknown. The present prospective study evaluated the effects of adjuvant chemotherapy on the cognitive performance of patients with localized CRC compared with a control group who had not undergone chemotherapy. PATIENTS AND METHODS: Consecutive patients with localized stage II and III CRC completed neuropsychological assessments, self-reported cognitive complaint questionnaires, and depressive symptom evaluations before starting fluoropyrimidine-based adjuvant chemotherapy and after 12 months. Blood was collected for apolipoprotein E genotyping. Diffusion tensor imaging data were acquired from a subset of participants at both evaluation points. RESULTS: From December 2012 to December 2014, 137 patients were approached and 85 were included. Of these 85 patients, 49 had undergone chemotherapy and 26 had not, in accordance with the standard recommendations for adjuvant therapy for CRC. The mean age was 62.5 +/- 9.4 years, 60% were men, and the mean educational attainment was 7.6 +/- 3.7 years. No difference was found in the global composite score (P = .38), attention (P = .84), or memory (P = .97) between the 2 groups during the follow-up period (mean +/- standard deviation, 375 +/- 29 days). However, a statistically significant difference was found for executive function after adjustment for age, sex, education, and depressive symptoms at baseline (beta -1.80; 95% confidence interval, -3.50 to -0.11; P = .04), suggesting worse performance for the chemotherapy group. For the 32 patients who had undergone magnetic resonance imaging, tract-based spatial statistics did not show voxelwise significant differences in structural brain connectivity at baseline or during follow-up. Apolipoprotein E polymorphisms were not predictive of cognitive dysfunction. CONCLUSION: Patients with CRC who received adjuvant 5-fluorouracil with or without oxaliplatin presented with a decline in executive function after 12 months compared with patients with localized disease who had not received chemotherapy. PMID- 30297265 TI - Association Between Primary Payer Status and Survival in Patients With Stage III Colon Cancer: An National Cancer Database Analysis. AB - BACKGROUND: Colon cancer is the third most frequent cancer diagnosis, and primary payer status has been shown to be associated with treatment modalities and survival in cancer patients. The goal of our study was to determine the between insurance differences in survival in patients with clinical stage III colon cancer using data from the National Cancer Database (NCDB). MATERIALS AND METHODS: We identified 130,998 patients with clinical stage III colon cancer in the NCDB diagnosed from 2004 to 2012. Kaplan-Meier curves and multivariable Cox regression models were used to determine the association between insurance status and survival. RESULTS: Patients with private insurance plans were 28%, 30%, and 16% less likely to die than were uninsured patients, Medicaid recipients, and Medicare beneficiaries, respectively. Medicare patients were 14% were less likely to die compared with uninsured patients. Patients receiving chemotherapy were, on average, 65% less likely to die compared with the patients not receiving chemotherapy. CONCLUSION: Private insurance and a greater socioeconomic status were associated with increased patient survival compared with other insurance plans or the lack of insurance. Future research should continue to unravel how socioeconomic status and insurance status contribute to the quality of care and survival of oncologic patients. PMID- 30297266 TI - Physical Activity Intensity and Cardiovascular Disease Prevention-From the Seguimiento Universidad de Navarra Study. AB - The association between the intensity of physical activity and the incidence of cardiovascular diseases (CVD), irrespective of energy expenditure (EE), requires further study. Our objective is to examine this relationship using data from a large Spanish cohort. The Seguimiento Universidad de Navarra cohort is formed of university graduates recruited from March 1999 to October 2015. We included 18,737 adults free of CVD (mean age 38 years, 61% women), with a median follow-up of 10.3 years. We estimated the average intensity of leisure time physical activity (LTPA) using a validated questionnaire. We classified respondents into 3 groups: Inactive, <6 average metabolic equivalents (METs) and >=6 average METs. We used Cox proportional hazards models adjusted by the EE in LTPA (MET-h/week) and other confounding factors, to examine this association. During 1,72,299 person-years of follow-up, we registered 127 cases of CVD (myocardial infarction, stroke, and death due to cardiovascular causes). The adjusted hazard ratio for CVD was 0.76 (95% CI 0.48 to 1.21) in the lower intensity group, and 0.31 (95% CI 0.12 to 0.79) in the higher intensity group, compared with the inactive, with a linear trend (p = 0.03). In conclusion, given the same level of EE, those respondents engaged in higher intensity LTPA, had a lower risk of CVD. PMID- 30297267 TI - Temporal Trends in Utilization of Right-Sided Heart Catheterization Among Percutaneous Ventricular Assist Device Recipients in Acute Myocardial Infarction Complicated by Cardiogenic Shock. AB - Percutaneous ventricular assist devices (PVAD) have been used at an increasing rate in patients with acute myocardial infarction complicated by cardiogenic shock (AMI-CS). Recent evidence has demonstrated that use of invasive hemodynamic monitoring with right-sided heart catheterization (RHC) was associated with improved survival in recipients of PVAD in AMI-CS. We sought to examine the utilization of RHC in patients receiving PVAD in AMI-CS. We queried the Nationwide Inpatient Sample database from 2008 to 2014 and identified patients using ICD-9-CM codes for AMI-CS (410, 785.51), PVAD (37.68), and RHC (37.21, 37.23). Temporal trends were analyzed using Cochrane Armitage test. In 5,925 patients who were treated with PVAD for AMI-CS, 1,691 (28.5%) underwent RHC. The mean (SD) age was 63.9 (12.3) years; majority were males (72.8%) and white (63.3%). Patients receiving RHC had higher baseline burden of co-morbidities, Charlson Co-morbidity Index >=2 (56.1%). From 2008 to 2014, there was decrease in the utilization of RHC in patients receiving PVAD from 40.4% to 29.8% (ptrend = 0.0005). Mortality decreased in patients who received RHC (56% to 42.6%, ptrend = 0.005), whereas mortality increased in patients without RHC (44.4% to 48.4%, ptrend = 0.001). In conclusion, in patients who present with AMI-CS and were treated with PVAD, there was a progressive decline in the utilization of RHC, despite a temporal decrease in mortality in patients receiving RHC. Novel strategies should be explored to increase the use of RHC in this high-risk patient population. PMID- 30297268 TI - Meta-Analysis Comparing Outcomes of Drug Eluting Stents Versus Single and Multiarterial Coronary Artery Bypass Grafting. AB - Relative benefits of coronary artery bypass (CABG) using single and multiple arterial grafting (SAG, MAG) and drug eluting stent (DES) in multivessel coronary disease remain uncertain. We compared SAG, MAG, and DES in a pairwise and network meta-analysis. Randomized trials and adjusted observational studies comparing CABG versus DES were included (primary end point: long-term mortality; secondary end points: operative mortality, perioperative stroke, and follow-up repeated revascularization [RR]). Studies with >=1.7 arterial grafts and/or patient were classified as MAG. Bayesian network meta-analyses and random-model pairwise meta analyses were performed. A total of 53,239 patients (8 randomized, 17 observational studies) were included (26,306 DES; 26,933 CABG). In pairwise comparison (mean follow-up: 5.42 years), CABG (MAG + SAG) was associated with lower long-term mortality (incident rate ratio [IRR] 0.77, 95% confidence interval [CI] 0.66 to 0.90), lower RR (IRR 0.37, 95% CI 0.27 to 0.51), increased perioperative stroke (odds ratio [OR] 3.18, 95% CI 1.70 to 5.97), and similar operative mortality (OR 1.04, 95% CI 0.64 to 1.70) compared with DES. There was a nonsignificant trend toward lower long-term mortality for studies with higher mean number of arterial grafts. In network meta-analyses, compared with DES, MAG was associated with lower long-term mortality (IRR 0.72, 95% credible interval [CrI] 0.57 to 0.92) and late RR (IRR 0.32, 95% CrI 0.21 to 0.49), SAG was associated with lower long-term mortality and RR (IRR 0.80, 95% CrI 0.66 to 0.97 and IRR 0.42, 95% CrI 0.29 to 0.61, respectively). In conclusion, CABG was associated with reduced 5-year mortality and need for RR compared with DES. MAG was ranked as the best treatment for the primary and all secondary outcomes.

AB - Today, in vivo allergy diagnosis and allergen-specific immunotherapy (AIT) are still based on allergen extracts obtained from natural allergen sources. Several studies analyzing the composition of natural allergen extracts have shown severe problems regarding their quality such as the presence of undefined nonallergenic materials, contaminants as well as high variabilities regarding contents and biological activity of individual allergens. Despite the increasing availability of sophisticated analytical technologies, these problems cannot be overcome because they are inherent to allergen sources and methods of extract production. For in vitro allergy diagnosis problems related to natural allergen extracts have been largely overcome by the implementation of recombinant allergen molecules that are defined regarding purity and biological activity. However, no such advances have been made for allergen preparations to be used in vivo for diagnosis and therapy. No clinical studies have been performed for allergen extracts available for in vivo allergy diagnosis that document safety, sensitivity, and specificity of the products. Only for very few therapeutic allergen extracts state-of-the-art clinical studies have been performed that provide evidence for safety and efficacy. In this article, we discuss problems related to the inconsistent quality of products based on natural allergen extracts and share our observations that most of the products available for in vivo diagnosis and AIT do not meet the international standards for medicinal products. We argue that a replacement of natural allergen extracts by defined recombinantly produced allergen molecules and/or mixtures thereof may be the only way to guarantee the supply of clinicians with state-of-the-art medicinal products for in vivo diagnosis and treatment of allergic patients in the future. PMID- 30297271 TI - United to end tuberculosis. PMID- 30297272 TI - No. 367-2019 Canadian Guideline for Physical Activity throughout Pregnancy. AB - OBJECTIVE: The objective is to provide guidance for pregnant women, and obstetric care and exercise professionals, on prenatal physical activity. OUTCOMES: The outcomes evaluated were maternal, fetal, or neonatal morbidity or fetal mortality during and following pregnancy. EVIDENCE: Literature was retrieved through searches of Medline, EMBASE, PsycINFO, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Scopus and Web of Science Core Collection, CINAHL Plus with Full-text, Child Development & Adolescent Studies, ERIC, Sport Discus, ClinicalTrials.gov, and the Trip Database from database inception up to January 6, 2017. Primary studies of any design were eligible, except case studies. Results were limited to English, Spanish, or French language materials. Articles related to maternal physical activity during pregnancy reporting on maternal, fetal, or neonatal morbidity or fetal mortality were eligible for inclusion. The quality of evidence was rated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. VALUES: The Guidelines Consensus Panel solicited feedback from end-users (obstetric care providers, exercise professionals, researchers, policy organizations, and pregnant and postpartum women). The development of this guideline followed the Appraisal of Guidelines for Research Evaluation (AGREE) II instrument. BENEFITS, HARMS, AND COSTS: The benefits of prenatal physical activity are moderate, and no harms were identified; therefore, the difference between desirable and undesirable consequences (net benefit) is expected to be moderate. The majority of stakeholders and end-users indicated that following these recommendations would be feasible, acceptable, and equitable. Following these recommendations is likely to require minimal resources from both individual and health systems perspectives. PREAMBLE: This guideline provide evidence-based recommendations regarding physical activity throughout pregnancy in the promotion of maternal, fetal, and neonatal health. In the absence of contraindications (see later for a detailed list), following this guideline is associated with: (1) fewer newborn complications (i.e., large for gestational age); and (2) maternal health benefits (i.e., decreased risk of preeclampsia, gestational hypertension, gestational diabetes, Caesarean section, instrumental delivery, urinary incontinence, excessive gestational weight gain, and depression; improved blood glucose; decreased total gestational weight gain; and decreased severity of depressive symptoms and lumbopelvic pain). Physical activity is not associated with miscarriage, stillbirth, neonatal death, preterm birth, preterm/prelabour rupture of membranes, neonatal hypoglycemia, low birth weight, birth defects, induction of labour, or birth complications. In general, more physical activity (frequency, duration, and/or volume) is associated with greater benefits. However, evidence was not identified regarding the safety or additional benefit of exercising at levels significantly above the recommendations. Prenatal physical activity should be considered a front-line therapy for reducing the risk of pregnancy complications and enhancing maternal physical and mental health. For pregnant women not currently meeting this guideline, a progressive adjustment toward them is recommended. Previously active women may continue physical activity throughout pregnancy. Women may need to modify physical activity as pregnancy progresses. There may be periods when following the guideline is not possible due to fatigue and/or discomforts of pregnancy; women are encouraged to do what they can and to return to following the recommendations when they are able. This guideline were informed by an extensive systematic review of the literature, expert opinion, end-user consultation and considerations of feasibility, acceptability, costs, and equity. RECOMMENDATIONS: The specific recommendations in this 2019 Canadian Guideline for Physical Activity Throughout Pregnancy are provided below with corresponding statements indicating the quality of the evidence informing the recommendations and the strength of the recommendations (explanations follow). CONTRAINDICATIONS: All pregnant women can participate in physical activity throughout pregnancy with the exception of those who have contraindications (listed below). Women with absolute contraindications may continue their usual activities of daily living but should not participate in more strenuous activities. Women with relative contraindications should discuss the advantages and disadvantages of moderate-to-vigorous intensity physical activity with their obstetric care provider prior to participation. Absolute contraindications to exercise are the following: Relative contraindications to exercise are the following: STRENGTH OF THE RECOMMENDATIONS: The GRADE system was utilized to grade the strength of the recommendations. Recommendations are rated as strong or weak based on the: (1) balance between benefits and harms; (2) overall quality of the evidence; (3) importance of outcomes (i.e., values and preferences of pregnant women); (4) use of resources (i.e., cost); (5) impact on health equity; (6) feasibility, and (7) acceptability. Strong recommendation: Most or all pregnant women will be best served by the recommended course of action. Weak recommendation: Not all pregnant women will be best served by the recommended course of action; there is a need to consider other factors such as the individual's circumstances, preferences, values, resources available, or setting. Consultation with an obstetric care provider may assist in decision making. QUALITY OF THE EVIDENCE: The quality of the evidence refers to the level of confidence in the evidence and ranges from very low to high. High quality: The Guideline Consensus Panel is very confident that the estimated effect of physical activity on the health outcome is close to the true effect. Moderate quality: The Guideline Consensus Panel is moderately confident in the estimated effect of physical activity on the health outcome; the estimate of the effect is likely to be close to the true effect, but there is a possibility that it is substantially different. Low quality: The Guideline Consensus Panel's confidence in the estimated effect of physical activity on the health outcome is limited; the estimate of the effect may be substantially different from the true effect. Very low quality: The Guideline Consensus Panel has very little confidence in the estimated effect of physical activity on the health outcome; the estimate of the effect is likely to be substantially different from the true effect. aThis was a weak recommendation because the quality of evidence was low, and the net benefit between women who were physically active and those who were not was small. bThis was a strong recommendation because, despite low quality evidence supporting physical activity during pregnancy for women categorized as overweight or obese, there was evidence from randomized controlled trials demonstrating an improvement in gestational weight gain and blood glucose. cModerate-intensity physical activity is intense enough to noticeably increase heart rate; a person can talk but not sing during activities of this intensity. Examples of moderate-intensity physical activity include brisk walking, water aerobics, stationary cycling (moderate effort), resistance training, carrying moderate loads, and household chores (e.g., gardening, washing windows). dThis was a weak recommendation because urinary incontinence was was not rated as a "critical" outcome and the evidence was low quality. eThis was a weak recommendation because: (1) the quality of evidence was very low; and (2) although harms were investigated there was limited available information to inform the balance of benefits and harms. This recommendation was primarily based on expert opinion. PMID- 30297273 TI - RNA sequencing (RNA-Seq) and its application in ovarian cancer. AB - Despite the surgical and chemotherapeutic advances over the past few decades, ovarian cancer remains the leading cause of gynecological cancer-related mortality. The absence of biomarkers in early detection and the development of drug resistance are principal causes of treatment failure in ovarian cancer. Recent progress in RNA sequencing (RNA-Seq) with Next Generation Sequencing technology has expanded the understanding of the molecular pathogenesis of ovarian cancer. As compared to previous hybridization-based microarray and Sanger sequence-based methods, RNA-Seq provides multiple layers of resolutions and transcriptome complexity, with less background noise and a broader dynamic range of RNA expression. Beyond quantifying gene expression, the data generated by RNA Seq accelerates the identification of alternatively spliced genes, fusion genes, mutations/SNPs, allele-specific expression, novel transcripts and non-coding RNAs. RNA-Seq has been successfully applied in ovarian cancer research for earlier detection, ascertaining pathological origin, and defining the aberrant genes and dysregulated molecular pathways across patient groups. This review outlines the distinct advantages of RNA-Seq compared to other transcriptomics methods and its recent applications in ovarian cancer.

PMID- 30297275 TI - Role of a pre-operative radiological scoring system in determining resectability for potentially resectable hilar cholangiocarcinoma. AB - AIMS: Cholangiocarcinoma is a rare cancer arising from the biliary tree. Case series indicate that 25-40% of all borderline resectable primary tumours are potentially resectable. The Memorial Sloane Kettering System (MSKCC) stratifies patients for resectability by longitudinal and radial extension of the hilar tumour. The Bismuth-Corlette system describes the longitudinal extension of the tumour within the biliary duct system. We sought to validate and, if possible, augment these two scores within an independent validation cohort. METHODS: Patients diagnosed with hilar cholangiocarcinoma between January 2009 and December 2016 were analysed from a prospectively held database. Patients with distal cholangiocarcinoma, peripheral cholangiocarcinoma and gallbladder cancer were excluded. Comparison of surgical findings to pre-operative radiological imaging was undertaken at the time of surgery. RESULTS: The validation cohort was formed of 198 patients, of which, 55 (27.8%) patients underwent resection. Logistic regression analyses identified that BC score, MSKCC score, age at diagnosis and left artery involvement were all significant independent predictor's univariately. BC score explained 28% of the variability in resectability compared to 26% explained by MSKCC. In combination, the model consisting of BC score, age at diagnosis and left artery involvement explained 39% of variability in resectability compared to the 34% explained same model including MSKCC score instead of BC score. CONCLUSION: In this cohort an augmented BC score, incorporating left hepatic artery involvement, is more discriminative in predicting resectability than the current MSKCC system.

PMID- 30297276 TI - Spanish Heart Transplant Registry. 29th Official Report of the Spanish Society of Cardiology Working Group on Heart Failure. AB - INTRODUCTION AND OBJECTIVES: The present report updates the characteristics and results of heart transplantation in Spain, mainly focused in the 2008-2017 period. METHODS: We describe the recipient and donor characteristics, surgical procedures, and outcomes of heart transplants performed in 2017. The 2017 data were compared with those obtained from 2008 to 2016. RESULTS: A total of 304 cardiac transplants were performed in 2017. Between 1984 and 2017, 8173 procedures were performed, 2689 of them after 2008. Significant temporal trends were observed in recipient characteristics (lower pulmonary vascular resistance, lower use of mechanical ventilation, and a higher percentage of diabetic patients and those with previous cardiac surgery), donor characteristics (older donor age and a higher percentage of female donors and those with a prior cardiac arrest) and procedures (lower ischemia time). In 2017, 27% of patients were transplanted after undergoing mechanical ventricular assistance (P <.001 for trend). In the last decade, there was a trend to better survival. CONCLUSIONS: Around 300 transplants per year were performed in Spain in the last decade. There was a significant increase in the use of pretransplant mechanical circulatory support and a trend to improved survival. PMID- 30297279 TI - Spanish Cardiac Catheterization and Coronary Intervention Registry. 27th Official Report of the Spanish Society of Cardiology Working Group on Cardiac Catheterization and Interventional Cardiology (1990-2017). AB - INTRODUCTION AND OBJECTIVES: To present the annual report of the Working Group on Cardiac Catheterization and Interventional Cardiology on the activity data for 2017. METHODS: Data were voluntarily provided by Spanish centers with a catheterization laboratory. The information was introduced online and was analyzed by the Steering Committee of the Working Group on Cardiac Catheterization and Interventional Cardiology. RESULTS: In 2017, data were reported by 107 hospitals, of which 82 are public. A total of 154 218 diagnostic procedures (138 448 coronary angiograms) were performed (2.2% increase vs 2016). The use of intracoronary diagnostic techniques significantly increased, especially that of pressure wire (23.2% vs 2016, n=7003). In 2017, the number of percutaneous coronary interventions rose to 70 928 (3.2% increase), of which 21 395 interventional procedures were performed in the acute myocardial infarction setting. A total of 105 529 stents were implanted, of which 90.3% were drug eluting stents (6% increase). Radial access was used in 85.7% of diagnostic procedures and in 88.4% of interventional procedures. The number of transcatheter aortic valve implantations continued to increase (28.2% increase, n=2821), as did the number of left atrial appendage closures (14.8% increase, n=582) and percutaneous mitral valve repair procedures (14.1% increase, n=270). CONCLUSIONS: Diagnostic and therapeutic procedures in acute myocardial infarction increased in 2017. The use of the radial approach and drug-eluting stents also increased in therapeutic procedures. The number of structural procedures rose significantly compared with previous years. PMID- 30297278 TI - Baseline Risk Stratification of Patients Older Than 75 Years With Infarction and Cardiogenic Shock Undergoing Primary Angioplasty. AB - BACKGROUND AND OBJECTIVES: Patients older than 75 years with ST-segment elevation myocardial infarction undergoing primary angioplasty in cardiogenic shock have high mortality. Identification of preprocedural predictors of short- and long term mortality could be useful to guide decision-making and further interventions. METHODS: We analyzed a nationwide registry of primary angioplasty in the elderly (ESTROFA MI+75) comprising 3576 patients. The characteristics and outcomes of the subgroup of patients in cardiogenic shock were analyzed to identify associated factors and prognostic predictors in order to derive a baseline risk prediction score for 1-year mortality. The score was validated in an independent cohort. RESULTS: A total of 332 patients were included. Baseline independent predictors of mortality were anterior myocardial infarction (HR 2.8, 95%CI, 1.4-6.0 P=.005), ejection fraction<40% (HR 2.3, 95%CI, 1.14-4.50 P=.018), and time from symptom onset to angioplasty >6hours (HR 3.2, 95%CI, 1.6-7.5; P=.001). A score was designed that included these predictive factors (score "6 ANT-40"). Survival at 1 year was 54.5% for patients with score 0, 32.3% for score 1, 27.4% for score 2 and 17% for score 3 (P=.004, c-statistic 0.70). The score was validated in an independent cohort of 124 patients, showing 1-year survival rates of 64.5%, 40.0%, 28.9%, and 22.2%, respectively (P=.008, c-statistic 0.68). CONCLUSIONS: A preprocedural score based on 3 simple clinical variables (anterior location, ejection fraction<40%, and delay time >6 hours) may be used to estimate survival after primary angioplasty in elderly patients with cardiogenic shock and to guide preinterventional decision-making. PMID- 30297280 TI - Impact of body mass index on outcomes after thoracic trauma-A matched-triplet analysis of the TraumaRegister DGU(r). AB - INTRODUCTION: Chest trauma and obesity are both associated with increased risks for respiratory complications (e.g. hypoxia, hypercarbia, pneumonia), which are frequent causes of posttraumatic morbidity and mortality. However, as there is only limited and inconsistent evidence, the aim of our study was to analyse the effect of body mass index (BMI) on patient outcomes after thoracic trauma. PATIENTS AND METHODS: We screened 50.519 patients entered in TraumaRegister DGU(r), between 2004-2009, when the BMI was part of the standardized dataset. After matching for injury patterns and severity of trauma we performed a matched tripled analysis with regard to the BMI (group 1: <25.0 kg/m2; group 2: 25.0-29.9 kg/m2; group 3: >30.0 kg/m2). Data are shown as percentages and mean values with standard deviation. RESULTS: The matching process yielded a cohort of 828 patients with serious blunt thoracic trauma, evenly distributed over the 3 BMI groups (276 triplets). BMI did not have an impact on the need for prehospital or emergency department interventions. There was a trend towards more liberal use of whole-body-CT scanning with increasing BMI (group 1: 68.8%; group 2: 73.2%; group 3: 75.0%). Additional abdominal injuries were more common in normal weight patients (Group 1: 28.3%; Group 2: 14.9%; Group 3: 17.8%). Obesity (BMI > 30.0 kg/m2) had a significant impact on the duration of mechanical ventilation (in days; group 1: 6.5 (9.4); group 2: 6.4 (8.9); group 3: 9.1 (14.4); p = 0.002), ICU days (in days; group 1: 11.5 (11.5); group 2: 10.9 (9.6); group 3: 14.1 (16.7); p = 0.005) and hospital length of stay (in days; group 1: 27.8 (19.3); group 2: 27.4 (19.2); group 3: 32.2 (25.9); p = 0.009). There were no significant differences regarding overall mortality (group 1: 3.6%; group 2: 1.8%; group 3: 4.0%; p = 0.26). CONCLUSIONS: Obesity has a negative impact on outcomes after blunt chest trauma, as it is associated with prolonged duration of mechanical ventilation, ICU and hospital length of stay. Mortality did not seem to be affected, yet, further research is required to confirm these results in a larger cohort. PMID- 30297281 TI - Structure-activity relationships of pyrazole-4-carbodithioates as antibacterials against methicillin-resistant Staphylococcus aureus. AB - Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of serious hospital-acquired infections and is responsible for significant morbidity and mortality in residential care facilities. New agents against MRSA are needed to combat rising resistance to current antibiotics. We recently reported 5-hydroxy-3 methyl-1-phenyl-1H-pyrazole-4-carbodithioate (HMPC) as a new bacteriostatic agent against MRSA that appears to act via a novel mechanism. Here, twenty nine analogs of HMPC were synthesized, their anti-MRSA structure-activity relationships evaluated and selectivity versus human HKC-8 cells determined. Minimum inhibitory concentrations (MIC) ranged from 0.5 to 64 MUg/mL and up to 16-fold selectivity was achieved. The 4-carbodithioate function was found to be essential for activity but non-specific reactivity was ruled out as a contributor to antibacterial action. The study supports further work aimed at elucidating the molecular targets of this interesting new class of anti-MRSA agents.

AB - As proteolytically stable peptidomimetics, peptoids could serve as antifungal agents to supplement a therapeutic field wrought with toxicity issues. We report the improvement of an antifungal peptoid, AEC5, through an iterative structure activity relationship study. A sarcosine scan was used to first identify the most pharmacophorically important peptoid building blocks of AEC5, followed by sequential optimization of each building block. The optimized antifungal peptoid from this study, beta-5, has improved potency towards Cryptococcus neoformans and decreased toxicity towards mammalian cells. For example, the selectivity ratio for C. neoformans over mammalian fibroblasts was improved from 8 for AEC5 to 37 for beta-5. PMID- 30297283 TI - Identification of steroidal derivatives inhibiting the transformations of allopregnanolone and estradiol by 17beta-hydroxysteroid dehydrogenase type 10. AB - 17beta-Hydroxysteroid dehydrogenase type 10 (17beta-HSD10) is a mitochondrial enzyme known for its potential role in Alzheimer's Disease (AD). 17beta-HSD10, by its oxidative activity, could decrease the concentration of two important neurosteroids, allopregnanolone (ALLOP) and 17beta-estradiol (E2), respectively preventing their neurogenesis and neuroprotective effects. Since the inhibition of 17beta-HSD10 could lead to a new treatment for AD, we developed two biological assays using labeled ALLOP or E2 as substrates to measure the inhibitory activity of compounds against pure 17beta-HSD10 protein. After the optimization of different parameters (time, concentration of enzyme, substrate and cofactor), analogs of the first reported steroidal inhibitor of 17beta-HSD10 in intact cells were screened to determine their inhibitory potency for the ALLOP or the E2 oxidation. One compound, androstane derivative 5, possesses the best dual inhibition against both transformations (ALLOP, IC50 = 235 MUM and E2, IC50 = 610 MUM). Some compounds are dual inhibitors to a lesser extent, and others seem selective for one of the transformations in particular. By developing two reliable assays and by identifying a first generation of steroidal inhibitors of pure 17beta-HSD10, this preliminary study opens the door to new and more potent inhibitors.

AB - The design and synthesis of a novel class of low-absorbable SGLT1 inhibitors are described. To achieve low absorption in the new series, we performed an optimization study based on a strategy to increase TPSA. Fortunately, the optimization of an aglycon moiety and a side chain of the distal aglycon moiety led to the identification of compound 30b as a potent and low-absorbable SGLT1 inhibitor. Compound 30b showed a desirable PK profile in Sprague-Dawley (SD) rats and a favorable glucose-lowering effect in diabetic rats. PMID- 30297285 TI - Design, synthesis and evaluation of curcumin-based fluorescent probes to detect Abeta fibrils. AB - Amyloid beta fibrillation is an early event in Alzheimer's disease, so its detection is important to understand its roles in Alzheimer's disease. Curcumin, which has poor water solubility, has been reported to have many pharmacological activities including potent anti-amyloid beta fibril activity in Alzheimer's disease. In this study, we found that curcumin analogues with the fluorescence property instead of non-inhibition of amyloid beta fibrils. The development of new curcumin analogue, Me-CUR (9), as fluorescent switchable probe to detect amyloid beta fibrils is described. Me-CUR (9) shows excellent fluorescence, especially higher than ThT (4), in the presence of amyloid beta fibrils. These results suggest that Me-CUR (9) can become a useful in vitro amyloid fluorescence sensor for diagnosis of Alzheimer's disease.

AB - OBJECTIVES: To summarize evidence regarding microbial dysbiosis of the airway associated with bronchopulmonary dysplasia (BPD) and to explore heterogeneity among studies. STUDY DESIGN: We included studies that evaluated the airway microbiome in preterm infants who developed BPD using culture-independent molecular techniques and reported alpha- and beta-diversity metrics and microbial profiles. RESULTS: The 6 included studies had substantial clinical and methodological heterogeneity. Most studies reported the presence of an airway microbiome early after birth and an evolution in the first weeks of life with increasing bacterial loads. The early airway microbiome was dominated by Staphylococcus and Ureaplasma spp. Two studies reported differences in alpha- and beta- diversity indices in preterm infants with BPD compared with those who did not develop BPD. Increased microbial community turnover, changes in the relative abundance of Proteobacteria and Firmicutes, and decreased Lactobacilli were reported with BPD progression. Most included infants were born by cesarean delivery, and a majority were exposed to postnatal antibiotics. No data regarding feeding human milk or correlations with the development of gut microbiota (gut lung axis) were available. CONCLUSIONS: Microbial dysbiosis may be associated with BPD progression and severity, and further study of microbiome optimization in preterm infants at risk for BPD is warranted.

PMID- 30297289 TI - Predicting Maintenance of Any Breastfeeding from Exclusive Breastfeeding Duration: A Replication Study. AB - OBJECTIVES: To predict the duration of any breastfeeding using the duration of exclusive breastfeeding in a socioeconomically heterogeneous sample of mothers using receiver operator characteristic (ROC) analysis. STUDY DESIGN: The Mother Baby Health Survey, a birth certificate-linked cross-sectional survey was sent at 4-5 months postpartum to a stratified random sample of socioeconomically and racially diverse women in upstate New York; 797 mothers who initiated exclusive breastfeeding were included in this study. Split-sample validation was employed; eligible subjects were divided into training or test samples at random (80% and 20%, respectively). ROC curves were constructed using the training sample and optimal exclusive breastfeeding duration thresholds were tested using the remaining test sample. Logistic regression using the training sample provided estimates of the predictive ability (sensitivity, specificity, positive predictive value) of thresholds in both unadjusted and adjusted analyses (covariates: age, education, parity, marital status, and race). RESULTS: The ROC analysis in this sample demonstrated that 9 weeks of exclusivity was required for maintenance of breastfeeding at 3 months, and 14.9 weeks of exclusivity was required for maintenance at 20 weeks. Unadjusted and adjusted models yielded similar results; women who exclusively breastfed for at least 9 weeks had 2.2 times the risk (95% CI 1.7-2.8) of maintaining any breastfeeding at 3 months. CONCLUSIONS: These results are similar to our previous results, from a less diverse cohort, and support that these thresholds may be useful in clinical settings for helping mothers achieve breastfeeding duration goals.

Among 23 rotavirus episodes observed during 18 months of surveillance of 100 families in Chile, 11 (48%) were identified as G8P[8]. Genotypes from these strains shared >99% identity with rotavirus sequences described in Asia, and may be misclassified as mixed G8/G12. PMID- 30297291 TI - Screening for Toxic Stress Risk Factors at Well-Child Visits: The Addressing Social Key Questions for Health Study. AB - OBJECTIVES: To determine the prevalence of and demographic characteristics associated with toxic stress risk factors by universal screening, the impact of screening on referral rates to community resources, and the feasibility and acceptability of screening in a medical home setting. STUDY DESIGN: We developed the Addressing Social Key Questions for Health Questionnaire, a 13-question screen of adverse childhood experiences (ACEs) and unmet social needs. Parents/guardians of children 0-17 years of age received this questionnaire at well-child visits at 4 academic clinics from August 1, 2016 to February 28, 2017. Providers reviewed the tool and referred to community resources as needed. A subset of families completed demographic and satisfaction surveys. Prevalence of ACEs and unmet social needs, community referral rates at 1 site with available data, and family acceptability data were collected. Analyses included frequency distributions, chi2 tests, and Poisson regression. RESULTS: Of 2569 families completing an Addressing Social Key Questions for Health Questionnaire, 49% reported >=1 stressor; 6% had >=1 ACE; 47% had >=1 unmet social need. At 1 site, community referral rates increased from 2.0% to 13.3% (P < .0001) after screening implementation. Risk factors for having a stressor include male sex and African American or Hispanic race. 86% of 446 families want clinics to continue screening. CONCLUSIONS: Universal screening for toxic stress risk factors in pediatric primary care improved identification and management of family needs. Screening was feasible and acceptable to families. Prevalence of unmet social needs but not ACEs was comparable with prior studies. Further evaluation and modification of the screening protocol is needed to increase screening and identification. PMID- 30297293 TI - Birth Hospitalization Costs and Days of Care for Mothers and Neonates in California, 2009-2011. AB - OBJECTIVE: To provide population-based estimates of the hospital-related costs of maternal and newborn care, and how these vary by gestational age and birth weight. STUDY DESIGN: We conducted a retrospective analysis of 2009-2011 California in-hospital deliveries at nonfederal hospitals with the infant and maternal discharge data successfully (96%) linked to birth certificates. Cost-to charge ratios were used to estimate costs from charges. Physician hospital payments were estimated by mean diagnosis related group-specific reimbursement and costs were adjusted for inflation to December 2017 values. After exclusions for incomplete or missing data, the final sample was 1 265 212. RESULTS: The mean maternal costs for all in-hospital deliveries was $8204, increasing to $13 154 for late preterm (32-36 weeks) and $22 702 for very preterm (<32 weeks) mothers. The mean cost for all newborns was $6389: $2433 for term infants, $22 102 for late preterm, $223 931 for very preterm infants, and $317 982 for extremely preterm infants (<28 weeks). Preterm infants were 8.1% of cases but incurred 60.9% of costs; for very preterm and extremely preterm infants, these shares were 1.0% and 36.5%, and 0.4% and 20.0%, respectively. Overall, mothers incurred 56% of the total costs during the delivery hospitalization. CONCLUSIONS: Both maternal and neonatal costs are skewed, with this being much more pronounced for infants. Preterm birth is much more expensive than term delivery, with the additional costs predominately incurred by the infants. The small share of infants who require extensive stays in neonatal intensive care incur a large share of neonatal costs and these costs have increased over time. PMID- 30297292 TI - Factors Associated with Adverse Outcomes among Febrile Young Infants with Invasive Bacterial Infections. AB - OBJECTIVE: To determine factors associated with adverse outcomes among febrile young infants with invasive bacterial infections (IBIs) (ie, bacteremia and/or bacterial meningitis). STUDY DESIGN: Multicenter, retrospective cohort study (July 2011-June 2016) of febrile infants <=60 days of age with pathogenic bacterial growth in blood and/or cerebrospinal fluid. Subjects were identified by query of local microbiology laboratory and/or electronic medical record systems, and clinical data were extracted by medical record review. Mixed-effect logistic regression was employed to determine clinical factors associated with 30-day adverse outcomes, which were defined as death, neurologic sequelae, mechanical ventilation, or vasoactive medication receipt. RESULTS: Three hundred fifty infants met inclusion criteria; 279 (79.7%) with bacteremia without meningitis and 71 (20.3%) with bacterial meningitis. Forty-two (12.0%) infants had a 30-day adverse outcome: 29 of 71 (40.8%) with bacterial meningitis vs 13 of 279 (4.7%) with bacteremia without meningitis (36.2% difference, 95% CI 25.1%-48.0%; P < .001). On adjusted analysis, bacterial meningitis (aOR 16.3, 95% CI 6.5-41.0; P < .001), prematurity (aOR 7.1, 95% CI 2.6-19.7; P < .001), and ill appearance (aOR 3.8, 95% CI 1.6-9.1; P = .002) were associated with adverse outcomes. Among infants who were born at term, not ill appearing, and had bacteremia without meningitis, only 2 of 184 (1.1%) had adverse outcomes, and there were no deaths. CONCLUSIONS: Among febrile infants <=60 days old with IBI, prematurity, ill appearance, and bacterial meningitis (vs bacteremia without meningitis) were associated with adverse outcomes. These factors can inform clinical decision making for febrile young infants with IBI. PMID- 30297294 TI - The Prevalence of Rib Fractures Incidentally Identified by Chest Radiograph among Infants and Toddlers. AB - OBJECTIVES: To determine the prevalence of incidental rib fractures identified by chest radiograph (CXR) obtained for indications unrelated to accidental trauma or nonaccidental trauma (NAT), and describe the histories associated with cases of incidental rib fractures and their proposed etiologies. It is hypothesized that incidental rib fractures are rare and alternative explanations for rib fractures occasionally used in a medico-legal context such as minor accidental trauma, undiagnosed medical conditions, and transient metabolic bone disturbances are unlikely to be the etiology of incidental rib fractures. STUDY DESIGN: A retrospective chart review of sequential CXRs of children ages 0 to <2 years was conducted from January 1, 2011 to October 31, 2016. CXRs were obtained in the emergency department, general pediatric or intensive care units, or outpatient pediatric clinics. Data collected included demographics, CXR indication and findings, history of cardiopulmonary resuscitation, laboratory and additional imaging results, and incidental rib fracture descriptions and proposed etiologies. RESULTS: A total of 7530 patients underwent 9720 CXRs associated with unique clinical encounters. Five CXRs had incidental rib fractures identified, making the prevalence of CXRs with incidental rib fractures in this cohort <0.1%. Of 5 identified incidental cases, mean age was 3.6 months, 3 were concerning for NAT, 1 was confirmed NAT, and 1 had radiographic findings consistent with osteopenia of prematurity. CONCLUSIONS: Identification of incidental rib fracture on CXR is rare. When detected in the absence of corresponding trauma history and/or objective laboratory or radiographic metabolic abnormalities, work-up for NAT should be pursued. PMID- 30297295 TI - Effects of Prone Sleeping on Cerebral Oxygenation in Preterm Infants. AB - OBJECTIVE: To determine the effect of prone sleeping on cerebral oxygenation in preterm infants in the neonatal intensive care unit. STUDY DESIGN: Preterm infants, divided into extremely preterm (gestational age 24-28 weeks; n = 23) and very preterm (gestational age 29-34 weeks; n = 33) groups, were studied weekly until discharge in prone and supine positions during active and quiet sleep. Cerebral tissue oxygenation index (TOI) and arterial oxygen saturation (SaO2) were recorded. Cerebral fractional tissue extraction (CFOE) was calculated as CFOE = (SaO2 - TOI)/SaO2. RESULTS: In extremely preterm infants, CFOE increased modestly in the prone position in both sleep states at age 1 week, in no change in TOI despite higher SaO2. In contrast, the very preterm infants did not have position-related differences in CFOE until the fifth week of life. In the very preterm infants, TOI decreased and CFOE increased with active sleep compared with quiet sleep and with increasing postnatal age. CONCLUSION: At 1 week of age, prone sleeping increased CFOE in extremely preterm infants, suggesting reduced cerebral blood flow. Our findings reveal important physiological insights in clinically stable preterm infants. Further studies are needed to verify our findings in unstable preterm infants regarding the potential risk of cerebral injury in the prone sleeping position in early postnatal life. PMID- 30297296 TI - Evaluation of the rs3088442 G>A SLC22A3 Gene Polymorphism and the Role of microRNA 147 in Groups of Adult Pakistani Populations With Type 2 Diabetes in Response to Metformin. AB - OBJECTIVES: Type 2 diabetes is a complex genetic disorder, and a large number of genetic polymorphisms may be involved in its pathogenesis. Pharmacologically, type 2 diabetes can be treated with 9 different approved classes of drugs, but metformin is suggested as the first line of therapy, followed by sulfonylureas. METHODS: This was a case-control study consisting of 300 metformin responders and 300 metformin nonresponders in patients with type 2 diabetes and 300 healthy Pakistani subjects. Genotyping of the SLC22A3 G>A polymorphism was performed by allele-specific polymerase chain reaction (PCR) for microRNA 147 expression; real time polymerase chain reaction was used, and expressional analysis of SLC22A3 was done by semiquantitative polymerase chain reaction. RESULTS: GA and AA genotypes were highly significantly associated with the drug treatments when compared with controls. A statistically significant difference was observed in the distribution of the SLC22A3 A allele between healthy subjects and patients with type 2 diabetes. When odds ratios were adjusted for glycated hemoglobin levels and postprandial and fasting blood glucose levels, our findings showed that the overexpression of allele A of the rs3088442 G>A variant may act as a protective allele and is associated with the clinical response to metformin. microRNA 147 expression was found to be increased in patients who were metformin responders compared with the nonresponder group and controls. mRNA expression of SLC22A3 was significantly reduced in patients taking metformin as compared to other groups. CONCLUSIONS: These results suggested that the SLC22A3 rs3088442 at position 2282 A allele may confer metformin clinical responses in patients with type 2 diabetes in the Pakistani population. Overexpression of microRNA 147 is associated with a downward expression of the SLC22A3 gene in patients who have type 2 diabetes. PMID- 30297297 TI - Intercellular Adhesion Molecule-1 Lys469Glu Polymorphism, Systemic Redox Homeostasis and Gestational Diabetes Mellitus in Pregnant Women. AB - OBJECTIVES: Intercellular adhesion molecule-1 (ICAM-1) plays an important role in endothelial function. Hyperglycemia-induced impaired redox status is 1 of the well-known pathophysiologic characteristics of gestational diabetes mellitus (GDM), and it plays a crucial role in the causes of disease. Our aim was to clarify any possible relationship between the ICAM-1 Lys469Glu polymorphism and systemic redox status in women with and without GDM. Also, we investigated whether this polymorphism could be associated with a change for better or worse as evidenced by clinical and redox biomarkers. METHODS: The ICAM-1 polymorphism statuses of 89 pregnant women without GDM and 53 pregnant women with GDM were found. Stratifying patients based on GDM and polymorphism status, we investigated various redox homeostasis markers. The independent t test was used. RESULTS: Significantly higher systemic oxidative damage and diminished antioxidant defense were found in pregnant women with GDM. Also, results showed that whether pregnant women were carrying the Lys469Glu polymorphism or not did not seem to be associated with significant differences, as evidenced by comparable systemic oxidative damage. CONCLUSIONS: Although no significant difference was observed between genotypes, the oxidative damage observed in patients with GDM warrants earlier screening and management in the light of new evidence. PMID- 30297298 TI - Storytelling to Support Disease Self-Management by Adults With Type 2 Diabetes. AB - OBJECTIVES: This pilot project aimed to examine the acceptability and feasibility of a group storytelling intervention to support self-management among adults living with type 2 diabetes. METHODS: Two waves of a single-arm storytelling intervention, consisting of 8 sessions at a community health centre, were delivered to 8 adults with type 2 diabetes. Diabetes educators facilitated each session, in which patients shared stories about diabetes-self-management topics of their choice. Focus groups with both patients and facilitators explored the feasibility and acceptability of the sessions. External raters assessed the fidelity of the intervention's implementation. RESULTS: Overarching themes describe the acceptability and feasibility of the intervention: 1) the facilitation of patient self-direction, group cohesion, collective learning and support; 2) roles of facilitator educator, and peer learner; 3) the intervention's customization to patients' preferences. The sessions were delivered with high fidelity (averaging 84.4%). CONCLUSIONS: Informal group storytelling enables patients to discuss, understand and give personal meaning to the information that was exchanged, and facilitates educators' better understanding of patients' concerns and gaps in knowledge and how-to strategies that can inform their practice. The group storytelling intervention is acceptable to patients and educators and can be delivered with high fidelity. Further research into effective patient recruitment methods and evaluation of the intervention's impact on diabetes self-management is required.

PMID- 30297300 TI - Impact of support agreement between municipalities and convenience store chain companies on store staff's support activities for older adults. AB - In the continuously aging society, private sectors are expected to play a role in older adult care. Implementing an agreement between municipalities and private sectors is one of the key mechanisms for encouraging private sectors to participate in supporting older adults. The study's aim was to evaluate whether the support agreement has promoted support activities by convenience store staff for older adults. A retrospective observational study was conducted between 2013 and 2016 using data from a nationwide survey of convenience stores. The municipality-level matching produced 168 municipality pairs, with 2242 convenience stores that entered into a support agreement with municipalities from 2014 to 2015, and 2141 stores without such an agreement. Convenience store-level logistic regression analysis evaluated the impact of the agreement on staff activities. The analysis showed that some staff activities increased significantly with the support agreement, such as corresponding or collaborating with community support centers (AOR = 3.40; 95% CI: 2.22 to 5.26), participating in role-playing programs for older adult care (AOR = 2.05; 95% CI: 1.01 to 4.26), and attending dementia support lectures (AOR = 18.21; 95% CI: 8.27 to 45.34). Emergency protection for older adults did not increase with the support agreement. The results suggest that the support agreement positively influenced some convenience store staff's support activities for older adults. PMID- 30297301 TI - 'I just want to be able to make a choice': Results from citizen deliberations about mammography screening in Ontario, Canada. AB - Despite Canada's long history with mammography screening, little is known about citizens' perspectives about mammography and how best to support women to make informed choices about screening. To address this gap, a series of four citizen deliberation events were held in 2015-16 in Ontario, a Canadian province with an organized population-based breast screening program in place since 1990. Forty nine individuals participated in four citizen panels, each comprising an information session highlighting the evidence about mammography, and large- and small-group deliberations about approaches to support informed decision making for screening. Following their engagement with the research evidence about mammography, participants expressed concern about their lack of full awareness of the risks and benefits and a strong desire for choice when it comes to screening. To support informed choice, mammography programs need to reflect the values of information sharing, trust and transparency, financial accountability, and allow for personal interactions and shared decision-making. Citizens are looking for balanced information about the risks and benefits of screening presented in an easy to understand, comprehensive, and transparent manner. Primary health care providers and organized screening programs are important sources of information about mammography and must be vigilant in their efforts to support informed decision-making in this area by ensuring that the information materials they are using are balanced and reflect current evidence. PMID- 30297302 TI - Growth of diabetes drug expenditure decomposed-A nationwide analysis. AB - OBJECTIVES: The aim of this study was to quantify different factors underlying the growth of diabetes drug expenditure in Finland. METHODS: Data representing purchases of antidiabetic agents between 2003 and 2015 were extracted from a nationwide prescription register. By using Fisher's Ideal Indexes, the per capita expenditure growth for both insulins and non-insulin antidiabetic agents was decomposed into six different determinants: purchase volume, purchase size, switches between therapeutic classes, switches within therapeutic classes, unit costs and switches to generic alternatives. RESULTS: Between 2003 and 2015, the per capita expenditure on insulins increased by ?8.64 and on non-insulins by ?13.73. For insulins, holding other factors constant, change in the number of purchases represented a ?4.67 increase in expenditure, change in the size of purchases a ?4.33 increase and switches between therapeutic classes a ?4.07 increase. For non-insulins, change in the number of purchases represented a ?10.22 increase in expenditure and switches between therapeutic classes, a ?10.17 increase. Changes in purchase size increased the non-insulin per capita expenditure by ?1.48. For both insulins and non-insulins, changes in prices and product level switches had decreasing effects on expenditures. CONCLUSIONS: The main drivers of the growth in diabetes drug expenditure were volume growth and switches to newer and more expensive drugs. Price changes, however, had a decreasing effect on the overall diabetes drug expenditure. PMID- 30297303 TI - Structure-activity profiling of alkaloid natural product pharmacophores against a Schistosoma serotonin receptor. AB - Serotonin (5-HT) is an important regulator of numerous aspects of flatworm biology, ranging from neuromuscular function to sexual maturation and egg laying. In the parasitic blood fluke Schistosoma mansoni, 5-HT targets several G-protein coupled receptors (GPCRs), one of which has been demonstrated to couple to cAMP and regulate parasite movement. This receptor, Sm.5HTRL, has been successfully co expressed in mammalian cells alongside a luminescent cAMP-biosensor, enabling pharmacological profiling for candidate anti-schistosomal drugs. Here, we have utilized this assay to perform structure-activity investigations of 143 compounds containing previously identified alkaloid natural product pharmacophores (tryptamines, aporphines and protoberberines) shown to regulate Sm.5HTRL. These experiments mapped regions of the tryptamine pharmacophore amenable and intolerant to substitution, highlighting differences relative to orthologous mammalian 5-HT receptors. Potent Sm.5HTRL antagonists were identified, and the efficacy of these compounds were evaluated against live adult parasites cultured ex vivo. Such structure-activity profiling, characterizing the effect of various modifications to these core ring systems on Sm.5HTRL responses, provides greater understanding of pharmacophores selective for this target to aid future drug development efforts. PMID- 30297304 TI - Reducing repeat imaging in hepato-pancreatico-biliary surgical cancer care through shared diagnostic imaging repositories. AB - BACKGROUND: With regionalization of care, patients often undergo treatment in institutions other than where the initial investigation is conducted. This study assessed the impact of a shared diagnostic imaging repository (SDIR) on processes of care and outcomes in hepato-pancreatico-biliary (HPB) cancer surgery. METHODS: Provincial administrative datasets were linked to study HPB cancer patients operated at a regional cancer centre (2003-2014). SDIR and non-SDIR groups were based on where initial imaging (CT or MRI) was conducted. Outcomes were repeat imaging before surgery and wait times for surgery from initial imaging and surgical consultation. RESULTS: Of 839 patients, 474 were from SDIR institutions. Fewer SDIR patients underwent any repeat imaging (55.9% vs. 75.3%; p < 0.01) and repeat imaging with same modality and protocol (24.7% vs. 43.0%; p < 0.01). Median wait time to surgery from initial imaging (64 Vs. 79 days; p < 0.01) and surgical consultation (39 Vs. 45 days; p = 0.046) was shorter with SDIR. SDIR patients had lower adjusted odds of any repeat imaging (OR 0.20 [0.14-0.30]), and repeat imaging with same modality and protocol (OR 0.58 [0.41-0.80]). CONCLUSION: Radiology sharing with SDIR reduced repeat imaging for HPB cancer surgery, including potentially redundant repeat imaging with same protocol, and shortened wait time to surgical care. PMID- 30297305 TI - Indocyanine green fluorescence imaging to evaluate graft perfusion during liver transplantation. AB - BACKGROUND: Primary graft dysfunction (PGD) is a leading cause of graft loss after liver transplantation. There is no reliable method to anticipate this complication intraoperatively. Indocyanine green (ICG) fluorescence imaging is a technique used in hepatobiliary surgery for detection of liver malignancies, but has never been reported in the setting of liver transplantation (LT) for function assessment. We hypothesized that there could be an association between the type of fluorescence and the occurrence of PGD. METHODS: We retrospectively analyzed 72 patients who underwent LT at our center. An assessment of the liver graft with the ICG fluorescence technique was carried out. A classification comprising 3 types of fluorescence was created after evaluation of the recorded images. We assessed the relationship between the type of fluorescence and the occurrence of PGD. RESULTS: Crosstabulation analysis of the fluorescent types and occurrence of PGD yielded a statistically significant association (p = 0.002). Univariate analysis showed that an abnormal ICG fluorescence pattern was a risk factor for the occurrence of PGD after LT. CONCLUSIONS: Our findings suggest that there could be an association between ICG fluorescence imaging and graft function. This intraoperative tool could be useful to detect patients at risk of developing PGD after LT. PMID- 30297306 TI - The effect of centralization on short term outcomes of pancreatoduodenectomy in a universal health care system. AB - BACKGROUND: Centralization of pancreatic resections is advocated due to a volume outcome association. Pancreatic surgery is in Norway currently performed only in five teaching hospitals. The aim was to describe the short-term outcomes after pancreatoduodenectomy (PD) within the current organizational model and to assess for regional disparities. METHODS: All patients who underwent PD in Norway between 2012 and 2016 were identified. Mortality (90 days) and relaparotomy (30 days) were assessed for predictors including demographic data and multi-visceral or vascular resection. Aggregated length-of-stay and national and regional incidences of the procedure were also analysed. RESULTS: A total of 930 patients underwent PD during the study period. In-hospital mortality occurred in 20 patients (2%) and 34 patients (4%) died within 90 days. Male gender, age, multi visceral resection and relaparotomy were independent predictors of 90-day mortality. Some 131 patients (14%) had a relaparotomy, with male gender and multi visceral resection as independent predictors. There was no difference between regions in procedure incidence or 90-day mortality. There was a disparity within the regions in the use of vascular resection (p = 0.021). CONCLUSION: The short term outcomes after PD in Norway are acceptable and the 90-day mortality rate is low. The outcomes may reflect centralization of pancreatic surgery. PMID- 30297307 TI - Mentoring the Next Generation of Authors. AB - OBJECTIVES: To discuss the role of mentoring in writing for publication, describe the specific needs of millennial learners, and offer tips for both mentor and mentee on how to foster and maintain a positive mentorship. DATA SOURCES: Published literature, online sources, personal experience. CONCLUSION: Mentorship can equip new nurse authors with the confidence, skills, and support needed to publish in a variety of forums. While a mentoring relationship primarily benefits the mentee, it can be equally rewarding for the mentor. IMPLICATIONS FOR NURSING PRACTICE: All oncology nurses have an opportunity to write about some part of their role in the care of people with cancer, yet most have not received formal training on how best to share their expertise and experience through publications. Mentorship can bridge this gap. PMID- 30297308 TI - Management of BIRADS 3, 4A, and 4B Lesions Diagnosed as Pure Papilloma by Ultrasound-Guided Core Needle Biopsy: Is Surgical Excision Necessary? AB - RATIONALE AND OBJECTIVES: There is lack of consensus on managing papillomas due to varied upgrade rates in the literature related to variability in the studied populations. We specifically studied upgrade rates of pure papilloma diagnosed with ultrasound core biopsy (UCB) using spring-loaded (SLB) and vacuum-assisted (VAB) biopsy devices in patients with low-to-intermediate pre-test probability for malignancy on imaging. MATERIALS & METHODS: From 01/01/2008 to 06/30/2016, 227 patients with 248 pure papillomas classified as BI-RADS 3, 4a, and 4b were diagnosed by UCB and underwent surgical excision or clinical and/or imaging follow-up. Imaging features, biopsy device, and final pathology were documented. RESULTS: 177 lesions were biopsied with SLB (14-gauge) and 71 lesions with VAB (9 13 gauges). At surgery, upgrade rates to high-risk lesions and malignancy for SLB were 14.3% (22/154) and 1.9% (3/154), and for VAB were 3.5% (2/57) and 0% (0/57), respectively (p <0.05). The combined surgical upgrade rate to high-risk lesions and malignancy was 11.4% (24/211) and 1.4% (3/211), respectively. The overall upgrade rate (including surgical and clinical and/or imaging follow-up) to high risk lesions and malignancy was 9.7% (24/248) and 1.2% (3/248), respectively. No ultrasound features were predictive of upgrade. Rates of complete excision were 7.1% (11/154) for SLB and 19.3% (11/57) for VAB (p < 0.05). CONCLUSION: BI-RADS 3, 4a, or 4b masses biopsied with UCB revealed pure papilloma upgrade to malignancy in less than 2% of cases. SLB was associated with greater upgrades compared with VAB. Therefore, follow-up imaging is a reasonable alternative to excision, particular in those sampled by VAB. Excision could be considered if the diagnosis of a high-risk lesion would change clinical management. PMID- 30297309 TI - Delivering paediatric critical care in humanitarian settings. PMID- 30297310 TI - Dual-Port versus Mono-Port Implantation for Intra-Arterial Chemoinfusion Therapy for Treatment of Hepatocellular Carcinoma in Patients with Anatomic Hepatic Artery Variation. AB - PURPOSE: To compare the feasibility and safety of mono-port catheter system and dual-port catheter system for advanced hepatocellular carcinoma (HCC) in patients with anatomic hepatic artery variation and portal vein tumor thrombosis. MATERIALS AND METHODS: This retrospective study consisted of 22 patients with infiltrative or multiple HCC with unilateral or bilateral portal vein thrombosis who had hepatic artery variation. A mono-port or dual-port catheter system was determined according to the degree of blood supply to the entire tumor through the common hepatic and variant hepatic arteries. Intrahepatic perfusion pattern, hepatic toxicity, and tumor response were investigated on computed tomography, medical records, and follow-up imaging study. RESULTS: The most common hepatic arterial variation was replaced right hepatic artery arising from the superior mesenteric artery (n = 16), followed by replaced left hepatic artery (n = 5) and replaced right posterior segmental artery (n = 1). Twelve patients were treated with mono-port catheter system, and 10 patients were treated with dual-port catheter system. All 10 patients in the dual-port group showed homogeneous distribution of contrast material in the entire liver after port implantation, and 6 patients (50%, n = 6/12) in the mono-port group showed heterogeneous distribution (P = .018). The objective tumor response rates (P = .361) were 18.2% and 40%, and the disease control rates (P = .395) were 36.4% and 60% in the mono port and dual-port groups, respectively. CONCLUSIONS: The dual-port ncatheter system is a safe and effective technique that allows the even distribution of hepatic arterial infusion chemotherapy without hemodynamic modification of anatomic variation in the hepatic arteries. PMID- 30297311 TI - Risk Assessment of Chronic Kidney Disease following Microwave Ablation for Stage T1 Renal Cell Carcinoma. AB - PURPOSE: To assess safety and renal-function outcomes after microwave (MW) ablation of localized stage T1 renal cell carcinoma (RCC). MATERIALS AND METHODS: A retrospective review was conducted of 38 patients (28 men; mean age, 69 y; range, 51-88 y) who underwent computed tomography (CT)-guided MW ablation for stage T1N0M0 RCC. Baseline and follow-up renal function surrogates including creatinine level and estimated glomerular filtration rate (eGFR) were statistically compared. Peri- and postoperative complication rates, technical success, and treatment response were also assessed. RESULTS: A total of 44 biopsy proven stage T1N0M0 RCCs measuring 1.2-6.9 cm (mean, 2.5 cm) were treated, and renal function was measured 1 mo after treatment. Mean eGFRs were 60 mL/min/1.73 m2 at baseline and 59 mL/min/1.73 m2 at 1 month after ablation. At 1-year and last follow-ups, the means of difference were 3.3% (95% confidence interval, -4.4 to 4.3; P = .99) and 3.3% (95% confidence interval, -4.3 to 4.8; P = .91), respectively. The 2-years freedom from eGFR decrease to < 60 mL/min/1.73 m2 was 2% (P = .91). Among the 5 patients (13%) with preexisting stage 4 chronic kidney disease (CKD; eGFR < 30 mL/min/1.73 m2) before ablation, there was no significant postablative onset of decline or CKD upstaging (P = .001). There were no major complications, and 5 patients (13%) had small asymptomatic perinephric hematomas (Society of Interventional Radiology minor complication, class A/B) that were managed conservatively. CONCLUSIONS: At 2-year follow-up, CT-guided percutaneous MW ablation is safe and well-tolerated and achieves nephron preservation similar to existing ablative modalities. PMID- 30297312 TI - Long-Term Outcomes of Iliofemoral Artery Stents after Transfemoral Aortic Valve Replacement. AB - PURPOSE: To report long-term results of iliofemoral stent placement after transcatheter aortic valve replacement (TAVR). MATERIALS AND METHODS: TAVR access related complications treated with iliofemoral stent placement were recorded in 56 patients (mean age, 81 years; range; 53-93 years; 48% male) of 648 patients who underwent TAVR at a single center. Fifty-six patients treated with stent placement (40 patients with stent grafts and 16 patients with bare metal stents) underwent clinical and ultrasonographic follow-up after a mean of 676 days (range, 60-1840 days). RESULTS: During follow-up, none of the 56 patients who had stent placement underwent a vascular reintervention of the affected limb, and none suffered from limb claudication. No decrease was observed in ankle-brachial index (ABI) values to an abnormal value, except in 1 patient (mean preprocedural and postprocedural ABI of 1.2 +/- 0.14, range, 0.97-1.4 and 1.19 +/- 0.24, range, 0.65-1.54, respectively). Arterial duplex assessment showed normal stent flow velocity (mean, 168.7 +/- 63.2 cm/sec; range, 80-345 cm/sec) in all but 1 patient. CONCLUSION: Iliofemoral stent implantation is a safe and efficacious treatment for vascular access site and access-related complications during transfemoral TAVR. PMID- 30297313 TI - Comparison of Clinical Outcomes of Prostatic Artery Embolization with 50-MUm Plus 100-MUm Polyvinyl Alcohol (PVA) Particles versus 100-MUm PVA Particles Alone: A Prospective Randomized Trial. AB - PURPOSE: To evaluate the safety and efficacy of prostatic artery embolization (PAE) using the combination of 50-MUm and 100-MUm polyvinyl alcohol (PVA) particles versus 100-MUm PVA particles alone in the treatment of patients with symptomatic benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Over a 5 year period, 120 patients treated with PAE for lower urinary tract symptoms (LUTS) secondary to BPH were randomized to undergo embolization with 50-MUm plus 100-MUm PVA particles (group A) or 100-MUm PVA particles alone (group B). Mean follow-up time was 34 months (range, 12-57 mo). There were no differences between groups regarding baseline data. Primary outcome measurements included change in International Prostate Symptom Score (IPSS) and incidence of adverse events. Secondary outcome measurements included procedure-associated pain, prostate ischemia measured on magnetic resonance (MR) imaging 1 week after PAE, and changes over time in quality of life (QOL) questionnaire, peak urinary flow rate (Qmax), postvoid residual (PVR) volume, prostate volume (PV), prostate-specific antigen (PSA) level, and International Index of Erectile Function (IIEF) were evaluated. Recurrence of LUTS following PAE was defined as relief of LUTS temporally but increased IPSS >= 8 or QOL score >= 3 or decrease in Qmax to < 7 mL/s. RESULTS: Mean follow-up periods were 35 months +/- 22 in group A and 33 months +/- 25 in group B (P = .629). No differences between groups regarding procedural details, pain scores, or adverse events were noted (P > .05). At 24 month of follow-up, patients in group A had a greater decrease in mean IPSS (18.7 +/- 12.5 vs 14.8 +/- 13.5), QOL score (3.7 +/- 1.5 vs 2.4 +/- 1.8), Qmax (10.5 mL +/- 9.5 vs 6.8 mL +/- 5.0), PVR (92.0 mL +/- 75.0 vs 60.0 mL +/- 55.0), and PV (37.0 mL +/- 19.5 vs 25.5 mL +/- 15.0) compared with patients in group B (P < .05 for all). Mean ratios of prostate ischemic volume at 1 week after PAE were 70% +/ 20 in group A and 41% +/- 25 in group B (P = .021); mean PSA levels at 24 hour after PAE were 92.5 ng/mL +/- 55.0 in group A and 77.5 ng/mL +/- 45.0 in group B (P = .031); LUTS recurrence rates were 3.6% in group A and 14.6% in group B (P = .024). The mean IIEF-5 was not significantly different from baseline in either group. CONCLUSIONS: PAE with 50-MUm plus 100-MUm PVA particles resulted in greater improvement in clinical and imaging outcomes and no significant differences in adverse events compared with 100-MUm PVA particles alone. PMID- 30297314 TI - Does intra-uterine insemination have a place in modern ART practice? AB - Intra-uterine insemination (IUI) is a cheaper, less intensive treatment modality for achieving a pregnancy in couples with specific indications. The use of IUI seems to have declined after NICE guideline 2013 (CG 156) recommended IVF over IUI in couples with unexplained and mild male factor infertility. This review examines the current evidence and the applicability of IUI as a first-line option of treatment in couples with unexplained and mild male factor subfertility. The outcome of the review supports this argument. It is likely that IUI will re emerge as an effective treatment option and thereby increase the choice to patients. However, there is a need for ongoing research and investment into funding of good quality trials to improve and strengthen the evidence base.

AB - Gestational diabetes mellitus (GDM) is the most common metabolic disturbance during pregnancy. The prevalence is rising and correlates with the increase in maternal obesity over recent decades. The etiology of GDM is complex, with genetic and environmental factors implicated in mechanistic and epidemiological studies. GDM begets important short- and long-term health risks for the mother, developing fetus, and offspring. This includes the high likelihood of subsequent maternal type 2 diabetes (T2DM), and possible adverse cardiometabolic phenotypes in the offspring. The most clinically and cost-effective methods of screening for GDM remain uncertain. Whilst treatments with lifestyle and pharmacological interventions have demonstrated short-term benefits, the long-term impact for the offspring of intrauterine exposure to antidiabetic medication remains unclear. PMID- 30297318 TI - Hypertensive ED patients: Missed opportunities for addressing hypertension and facilitating outpatient follow-up. AB - OBJECTIVES: Hypertension is a leading cause of morbidity and mortality. The emergency department (ED) frequently serves populations with unmet health needs and could have a greater and more systematic role in secondary prevention for hypertension. This study sought to determine, among hypertensive patients discharged from the ED, the frequency that patients 1) received hypertension specific education, and 2) followed-up with a primary care provider. We secondarily assessed participant beliefs about hypertension. METHODS: This non experimental, observational study enrolled a convenience sample of consenting patients with asymptomatic, markedly elevated blood pressure (systolic >=160 mmHg or diastolic >=100 mmHg) with medium to low triage acuity discharged from an urban, academic ED. Discharge instructions were assessed through chart review. Patients followed up per their normal routine without intervention. Participants were interviewed by phone two to four weeks after ED discharge to ascertain outpatient follow-up and describe beliefs about hypertension. RESULTS: From April through June 2014, 200 patients were approached, of whom 90 were enrolled. Of these, 77% of patients reported a previous diagnosis of hypertension, and 60% reported current treatment with antihypertensive medications. Five patients (5.5%) received written instructions at discharge addressing hypertension, although 59 (65.6%) reported that they were informed about their elevated blood pressure during the ED visit. Follow-up with a primary care provider within 2-4 weeks of discharge was completed in 57% of cases. None of the patients who received hypertension-specific discharge instructions completed follow-up. CONCLUSIONS: Over half of markedly hypertensive patients discharged from the ED followed up with primary care within four weeks. Nonetheless, missed opportunities for improved secondary prevention among ED patients with hypertension are common. There is an urgent need for evidence-based interventions to assist emergency departments in addressing this health threat. PMID- 30297320 TI - Central Obesity, Faster Maturation, and 'PCOS' in Girls. AB - Polycystic ovary syndrome (PCOS) development commonly starts with a mismatch between pre- and postnatal weight gain, leading to hepatovisceral fat excess. To escape from such central obesity, girls may accelerate their growth and/or maturation. This homeostatic mechanism is lost upon reaching adult height, and PCOS may ensue. Prevention and/or treatment of PCOS should aim at reducing central fat excess. PMID- 30297321 TI - The need for new treatment recommendations for trichomoniasis among women. PMID- 30297323 TI - Can transcranial electric stimulation with multiple electrodes reach deep targets? AB - To reach a deep target in the brain with transcranial electric stimulation (TES), currents have to pass also through the cortical surface. Thus, it is generally thought that TES cannot achieve focal deep brain stimulation. Recent efforts with interfering waveforms and pulsed stimulation have argued that one can achieve deeper or more intense stimulation in the brain. Here we argue that conventional transcranial stimulation with multiple current sources is just as effective as these new approaches. The conventional multi-electrode approach can be numerically optimized to maximize intensity or focality at a desired target location. Using such optimal electrode configurations we find in a detailed and realistic head model that deep targets may in fact be strongly stimulated, with cerebro-spinal fluid guiding currents deep into the brain. PMID- 30297324 TI - The physiological role of the free 20S proteasome in protein degradation: A critical review. AB - BACKGROUND: It has been almost three decades since the removal of oxidized proteins by the free 20S catalytic unit of the proteasome (20SPT) was proposed. Since then, experimental evidence suggesting a physiological role of proteolysis mediated by the free 20SPT has being gathered. SCOPE OF REVIEW: Experimental data that favors the hypothesis of free 20SPT as playing a role in proteolysis are critically reviewed. MAJOR CONCLUSIONS: Protein degradation by the proteasome may proceed through multiple proteasome complexes with different requirements though the unequivocal role of the free 20SPT in cellular proteolysis towards native or oxidized proteins remains to be demonstrated. GENERAL SIGNIFICANCE: The biological significance of proteolysis mediated by the free 20SPT has been elusive since its discovery. The present review critically analyzes the available experimental data supporting the proteolytic role of the free or single capped 20SPT. PMID- 30297322 TI - Single-dose versus 7-day-dose metronidazole for the treatment of trichomoniasis in women: an open-label, randomised controlled trial. AB - BACKGROUND: Among women, trichomoniasis is the most common non-viral sexually transmitted infection worldwide, and is associated with serious reproductive morbidity, poor birth outcomes, and amplified HIV transmission. Single-dose metronidazole is the first-line treatment for trichomoniasis. However, bacterial vaginosis can alter treatment efficacy in HIV-infected women, and single-dose metronidazole treatment might not always clear infection. We compared single-dose metronidazole with a 7-day dose for the treatment of trichomoniasis among HIV uninfected, non-pregnant women and tested whether efficacy was modified by bacterial vaginosis. METHODS: In this multicentre, open-label, randomised controlled trial, participants were recruited at three sexual health clinics in the USA. We included women positive for Trichomonas vaginalis infection according to clinical screening. Participants were randomly assigned (1:1) to receive either a single dose of 2 g of metronidazole (single-dose group) or 500 mg of metronidazole twice daily for 7 days (7-day-dose group). The randomisation was done by blocks of four or six for each site. Patients and investigators were aware of treatment assignment. The primary outcome was T vaginalis infection by intention to treat, at test-of-cure 4 weeks after completion of treatment. The analysis of the primary outcome per nucleic acid amplification test or culture was also stratified by bacterial vaginosis status. This trial is registered with ClinicalTrials.gov, number NCT01018095, and with the US Food and Drug Administration, number IND118276, and is closed to accrual. FINDINGS: Participants were recruited from Oct 6, 2014, to April 26, 2017. Of the 1028 patients assessed for eligibility, 623 women were randomly assigned to treatment groups (311 women in the single-dose group and 312 women in the 7-day-dose group; intention-to-treat population). Although planned enrolment had been 1664 women, the study was stopped early because of funding limitations. Patients in the 7-day dose group were less likely to be T vaginalis positive at test-of-cure than those in the single-dose group (34 [11%] of 312 vs 58 [19%] of 311, relative risk 0.55, 95% CI 0.34-0.70; p<0.0001). Bacterial vaginosis status had no significant effect on relative risk (p=0.17). Self-reported adherence was 96% in the 7-day-dose group and 99% in the single-dose group. Side-effects were similar by group; the most common side-effect was nausea (124 [23%]), followed by headache (38 [7%]) and vomiting (19 [4%]). INTERPRETATION: The 7-day-dose metronidazole should be the preferred treatment for trichomoniasis among women. FUNDING: National Institutes of Health.

AB - OBJECTIVE: Cutaneous neonatal lupus (cNL) occurs in possibly 5%-16% of anti-Ro+/ anti-La antibody-exposed infants. Data suggest in utero exposure to hydroxychloroquine (HCQ) may prevent cardiac NL. The aim was to assess whether in utero exposure to HCQ decreases the risk of cNL and/or delays onset. METHODS: A multicentre case-control study was performed with 122 cNL cases and 434 controls born to women with a rheumatological disease who had documentation of maternal anti-Ro+/-anti-La antibodies at pregnancy and confirmation of medication use and the child's outcome. A secondary analysis was performed on 262 cNL cases, irrespective of maternal diagnosis, to determine if HCQ delayed time to cNL onset. RESULTS: Twenty (16%) cNL cases were exposed to HCQ compared with 146 (34%) controls (OR 0.4 (95% CI 0.2 to 0.6); p<0.01). Exposure to HCQ was associated with a reduced risk of cNL; exposure to anti-La antibody and female gender were associated with an increased risk of cNL. Exposure to HCQ remained significantly associated with a reduced cNL risk in the analyses limited to mothers with systemic lupus erythematosus and those who developed rash <=1 month. When analysing all 262 cNL cases, HCQ-exposed infants were older (6.0 (95% CI 5.7 to 6.3) weeks) at cNL onset versus HCQ-non-exposed infants (4.4 (95% CI 3.9 to 5.0) weeks), but the difference was not statistically significant (p=0.21). CONCLUSION: Exposure to HCQ was associated with a reduced risk of cNL. Among cNL cases, those exposed to HCQ tend to have later onset of rash. Both findings suggest a protective effect of HCQ on cNL.

PMID- 30297332 TI - Incidence, prevalence and treatment burden of polymyalgia rheumatica in the UK over two decades: a population-based study. AB - OBJECTIVE: Polymyalgia rheumatica (PMR) is the most common inflammatory rheumatic disease in older people. Contemporary estimates of the incidence and prevalence are lacking, and no previous study has assessed treatment patterns at a population level. This study aims to address this. METHODS: We extracted anonymised electronic medical records of patients over the age of 40 years from the Clinical Practice Research Datalink in the period 1990-2016. The absolute rate of PMR per 100 000 person-years was calculated and stratified by age, gender and calendar year. Incidence rate ratios were calculated using a Poisson regression model. Among persons with PMR, continuous and total duration of treatment with glucocorticoids (GC) were assessed. RESULTS: 5 364 005 patients were included who contributed 44 million person-years of follow-up. 42 125 people had an incident diagnosis of PMR during the period. The overall incidence rate of PMR was 95.9 per 100 000 (95% CI 94.9 to 96.8). The incidence of PMR was highest in women, older age groups and those living in the South of England. Incidence appears stable over time. The prevalence of PMR in 2015 was 0.85 %. The median (IQR) continuous GC treatment duration was 15.8 (7.9-31.2) months. However, around 25% of patients received more than 4 years in total of GC therapy. CONCLUSIONS: The incidence rates of PMR have stabilised. This is the first population-based study to confirm that a significant number of patients with PMR receive prolonged treatment with GC, which can carry significant risks. The early identification of these patients should be a priority in future research. PMID- 30297331 TI - Identification of a distinct imaging phenotype may improve the management of palindromic rheumatism. AB - OBJECTIVES: To use high-resolution imaging to characterise palindromic rheumatism (PR) and to compare the imaging pattern observed to that seen in new-onset rheumatoid arthritis (NORA). METHODS: Ultrasound (US) assessment of synovitis, tenosynovitis and non-synovial extracapsular inflammation (ECI) was performed during and between flares in a prospective treatment-naive PR cohort. MRI of the flaring region was performed where possible. For comparison, the same US assessment was also performed in anticyclic citrullinated peptide (CCP) positive individuals with musculoskeletal symptoms (CCP+ at risk) and patients with NORA. RESULTS: Thirty-one of 79 patients with PR recruited were assessed during a flare. A high frequency of ECI was identified on US; 19/31 (61%) of patients had ECI including 12/19 (63%) in whom ECI was identified in the absence of synovitis. Only 7/31 (23%) patients with PR had synovitis (greyscale >=1 and power Doppler >=1) during flare. In the hands/wrists, ECI was more prevalent in PR compared with NORA and CCP+ at risk (65% vs 29 % vs 6%, p<0.05). Furthermore, ECI without synovitis was specific for PR (42% PR vs 4% NORA (p=0.003) and 6% CCP+ at risk (p=0.0012)). Eleven PR flares were captured by MRI, which was more sensitive than US for synovitis and ECI. 8/31 (26%) patients with PR developed RA and had a similar US phenotype to NORA at progression. CONCLUSION: PR has a distinct US pattern characterised by reversible ECI, often without synovitis. In patients presenting with new joint swelling, US may refine management by distinguishing relapsing from persistent arthritis. PMID- 30297333 TI - Rheumatoid arthritis-associated DNA methylation sites in peripheral blood mononuclear cells. AB - OBJECTIVES: To identify novel DNA methylation sites significant for rheumatoid arthritis (RA) and comprehensively understand their underlying pathological mechanism. METHODS: We performed (1) genome-wide DNA methylation and mRNA expression profiling in peripheral blood mononuclear cells from RA patients and health controls; (2) correlation analysis and causal inference tests for DNA methylation and mRNA expression data; (3) differential methylation genes regulatory network construction; (4) validation tests of 10 differential methylation positions (DMPs) of interest and corresponding gene expressions; (5) correlation between PARP9 methylation and its mRNA expression level in Jurkat cells and T cells from patients with RA; (6) testing the pathological functions of PARP9 in Jurkat cells. RESULTS: A total of 1046 DNA methylation positions were associated with RA. The identified DMPs have regulatory effects on mRNA expressions. Causal inference tests identified six DNA methylation-mRNA-RA regulatory chains (eg, cg00959259-PARP9-RA). The identified DMPs and genes formed an interferon-inducible gene interaction network (eg, MX1, IFI44L, DTX3L and PARP9). Key DMPs and corresponding genes were validated their differences in additional samples. Methylation of PARP9 was correlated with mRNA level in Jurkat cells and T lymphocytes isolated from patients with RA. The PARP9 gene exerted significant effects on Jurkat cells (eg, cell cycle, cell proliferation, cell activation and expression of inflammatory factor IL-2). CONCLUSIONS: This multistage study identified an interferon-inducible gene interaction network associated with RA and highlighted the importance of PARP9 gene in RA pathogenesis. The results enhanced our understanding of the important role of DNA methylation in pathology of RA. PMID- 30297335 TI - Vitamin D supplements do not protect bone health, analysis finds. PMID- 30297334 TI - Risk-adjusted mortality of VLBW infants in high-volume versus low-volume NICUs. AB - OBJECTIVE: To examine whether the number of very low birthweight (VLBW) infants treated annually in neonatal intensive care units (NICUs) (hospital volume) has an effect on their in-hospital mortality under the regulatory conditions in Germany. SETTING: The study included VLBW infants with <33 weeks of gestational age and birth weight below 1500 g admitted to NICUs in the state of Baden Wuerttemberg, Germany, from 2003 to 2008. Cases were extracted from the compulsory German neonatal quality assurance programme with variables essential for calculation of the Clinical Risk Index for Babies (CRIB) and PREM birth model (PREM(bm)) scores. The cohort was divided into four subgroups corresponding to their disease severity (low, intermediate, high and very high) according to each score. Low-volume NICUs (LV-NICUs) were defined as treating up to 50 cases per year, while high-volume NICUs >50 cases. RESULTS: After exclusion of infants with lethal malformations, 5340 cases from 32 units were analysed. While raw mortality was comparable, infants in LV-NICUs had an increased mortality after risk adjustment with the CRIB and PREM(bm) scores (OR 1.48 (95% CI 1.16 to 1.90), p=0.002 with CRIB; and OR 1.39 (95% CI 1.11 to 1.76), p=0.005 with PREM(bm)). In a subgroup analysis mortality was significantly higher for LV-NICUs in the intermediate disease severity group (OR 1.49 (95% CI 1.02 to 2.17), p=0.037 with CRIB) and in the high-risk group (OR 1.70 (95% CI 1.16 to 1.90), p=0.002 with CRIB; and OR 1.39 (95% CI 1.11 to 1.76), p=0.005 with PREM(bm)), but not in the low-risk and very high-risk subgroups. CONCLUSION: Depending on the severity of the disease, the risk-adjusted mortality in German NICUs with 50 or less annual cases of VLBW infants may be significantly increased. PMID- 30297336 TI - Novel gene targets for miRNA146a and miRNA155 in anterior uveitis. AB - BACKGROUND/AIMS: Anterior uveitis (AU) is the most common form of intraocular inflammation. MicroRNAs (miRNA) are small, non-coding RNAs functioning as post transcriptional repressors of gene expression. Knowledge of miRNAs can implicate specific genes and pathogenic signalling pathways in disease. This study examines miRNA expression, function and target genes in AU pathogenesis. METHODS: AU and healthy control (HC) peripheral blood mononuclear cells (PBMC) were initially screened for expression of five miRNAs by real-time PCR. Regulation of the aberrantly expressed miRNAs by TLR1/2, TLR3, TLR4, IL1beta and TNFalpha was quantified by real-time PCR and paired cytokine outputs measured by ELISA. Functional effects of miRNA overexpression using transfected THP1 cells examined IL6, IL8, IL10 and IL1beta cytokine outputs by ELISA. Target genes were identified using TargetScan online computational algorithm and relevant targets verified by cloning of the 3'UTR and luciferase reporter gene assays. RESULTS: Increased expression of miRNA146a (p<0.01), miRNA155 (p<0.05) and miRNA125a5p (p<0.01) was demonstrated in AU PBMC compared with HC. miRNA155 was increased following TLR1/2 (p<0.05) and TLR4 (p<0.05) stimulation and miRNA146a increased in response to IL1beta (p<0.05). In a proinflammatory environment, miRNA155 overexpression in THP1 cells yielded increased cytokine output whereas miRNA146a overexpression showed decreased cytokine output. CD80, PRKCE and VASN were confirmed as novel targets for miRNA146a and SMAD2, TYRP1 and FBXO22 for miRNA155. CONCLUSION: This study identifies overexpression of proinflammatory miRNA155, regulatory miRNA146a and miRNA125a-5p in AU. CD80, PRKCE and VASN are novel miRNA146a targets and SMAD2, TYRP1 and FBXO22 are novel targets for miRNA155. PMID- 30297338 TI - Who are Sierra Leone's health security efforts for? PMID- 30297337 TI - Macular spatial distribution of preserved autofluorescence in patients with choroideremia. AB - BACKGROUND/AIMS: To better understand the pattern of degeneration progression in cases with choroideremia. METHODS: A cohort of genotypically confirmed choroideremia cases who underwent optical coherence tomography (OCT) and fundus autofluorescence (FAF) imaging was studied. Using HEYEX review software, the foveal centre was marked on FAF images under guidance of corresponding OCT images, followed by application of an ETDRS grid. The boundaries of preserved autofluorescence (AF) were manually segmented in each individual ETDRS subfield. The regional distribution of preserved AF was assessed by comparing its area among the various subfields. RESULTS: A total of 168 eyes from 84 choroideremia cases were enrolled. There was a statistically significant difference in the amount of preserved AF area between inner subfields as determined by one-way analysis of variance (F (3,668)=9.997, p<0.001) and also between outer subfields (F (3,668)=8.348, p<0.001). A Tukey posthoc test revealed that the preserved AF area in the nasal subfields in both the inner and outer subfields was significantly smaller compared with analogue subfields. CONCLUSION: The asymmetric spatial distribution of preserved AF in choroideremia (corresponding to the stellate shaped nature of these regions) suggests that the progression of degeneration has directional preference. PMID- 30297340 TI - RNA Splicing in the Transition from B Cells to Antibody-Secreting Cells: The Influences of ELL2, Small Nuclear RNA, and Endoplasmic Reticulum Stress. AB - In the transition from B cells to Ab-secreting cells (ASCs) many genes are induced, such as ELL2, Irf4, Prdm1, Xbp1, whereas other mRNAs do not change in abundance. Nonetheless, using splicing array technology and mouse splenic B cells plus or minus LPS, we found that induced and "uninduced" genes can show large differences in splicing patterns between the cell stages, which could influence ASC development. We found that ~55% of these splicing changes depend on ELL2, a transcription elongation factor that influences expression levels and splicing patterns of ASC signature genes, genes in the cell-cycle and N-glycan biosynthesis and processing pathways, and the secretory versus membrane forms of the IgH mRNA. Some of these changes occur when ELL2 binds directly to the genes encoding those mRNAs, whereas some of the changes are indirect. To attempt to account for the changes that occur in RNA splicing before or without ELL2 induction, we examined the amount of the small nuclear RNA molecules and found that they were significantly decreased within 18 h of LPS stimulation and stayed low until 72 h. Correlating with this, at 18 h after LPS, endoplasmic reticulum stress and Ire1 phosphorylation are induced. Inhibiting the regulated Ire1 dependent mRNA decay with 4u8C correlates with the reduction in small nuclear RNA and changes in the normal splicing patterns at 18 h. Thus, we conclude that the RNA splicing patterns in ASCs are shaped early by endoplasmic reticulum stress and Ire1 phosphorylation and later by ELL2 induction. PMID- 30297339 TI - Differential and Overlapping Immune Programs Regulated by IRF3 and IRF5 in Plasmacytoid Dendritic Cells. AB - We examined the signaling pathways and cell type-specific responses of IFN regulatory factor (IRF) 5, an immune-regulatory transcription factor. We show that the protein kinases IKKalpha, IKKbeta, IKKepsilon, and TANK-binding kinase 1 each confer IRF5 phosphorylation/dimerization, thus extending the family of IRF5 activator kinases. Among primary human immune cell subsets, we found that IRF5 is most abundant in plasmacytoid dendritic cells (pDCs). Flow cytometric cell imaging revealed that IRF5 is specifically activated by endosomal TLR signaling. Comparative analyses revealed that IRF3 is activated in pDCs uniquely through RIG I-like receptor (RLR) signaling. Transcriptomic analyses of pDCs show that the partitioning of TLR7/IRF5 and RLR/IRF3 pathways confers differential gene expression and immune cytokine production in pDCs, linking IRF5 with immune regulatory and proinflammatory gene expression. Thus, TLR7/IRF5 and RLR-IRF3 partitioning serves to polarize pDC response outcome. Strategies to differentially engage IRF signaling pathways should be considered in the design of immunotherapeutic approaches to modulate or polarize the immune response for specific outcome. PMID- 30297341 TI - Can rapid approaches to qualitative analysis deliver timely, valid findings to clinical leaders? A mixed methods study comparing rapid and thematic analysis. AB - OBJECTIVES: This study compares rapid and traditional analyses of a UK health service evaluation dataset to explore differences in researcher time and consistency of outputs. DESIGN: Mixed methods study, quantitatively and qualitatively comparing qualitative methods. SETTING: Data from a home birth service evaluation study in a hospital in the English National Health Service, which took place between October and December 2014. Two research teams independently analysed focus group and interview transcript data: one team used a thematic analysis approach using the framework method, and the second used rapid analysis. PARTICIPANTS: Home birth midwives (6), midwifery support workers (4), commissioners (4), managers (6), and community midwives (12) and a patient representative (1) participated in the original study. PRIMARY OUTCOME MEASURES: Time taken to complete analysis in person hours; analysis findings and recommendations matched, partially matched or not matched across the two teams. RESULTS: Rapid analysis data management took less time than thematic analysis (43 hours vs 116.5 hours). Rapid analysis took 100 hours, and thematic analysis took 126.5 hours in total, with interpretation and write up taking much longer in the rapid analysis (52 hours vs 8 hours). Rapid analysis findings overlapped with 79% of thematic analysis findings, and thematic analysis overlapped with 63% of the rapid analysis findings. Rapid analysis recommendations overlapped with 55% of those from the thematic analysis, and thematic analysis overlapped with 59% of the rapid analysis recommendations. CONCLUSIONS: Rapid analysis delivered a modest time saving. Excessive time to interpret data in rapid analysis in this study may be due to differences between research teams. There was overlap in outputs between approaches, more in findings than recommendations. Rapid analysis may have the potential to deliver valid, timely findings while taking less time. We recommend further comparisons using additional data sets with more similar research teams. PMID- 30297342 TI - Comparative, cross-sectional study of the format, content and timing of medication safety letters issued in Canada, the USA and the UK. AB - OBJECTIVES: To assess consistency in the format and content, and overlap of subject and timing, of medication safety letters issued by regulatory health authorities to healthcare providers in Canada, the USA and the UK. DESIGN: A cross-sectional study comparing medication safety letters issued for the purpose of alerting healthcare providers to newly identified medication problems associated with medications already on the market. SETTING: Online databases operated by Health Canada, the US Food and Drug Administration and the UK Medicines and Healthcare products Regulatory Agency were searched to select medication safety letters issued between 1 January 2010 and 31 December 2014. Format, content and timing of each medication safety letter were assessed using an abstraction tool comprising 21 characteristics deemed relevant by consensus of the research team. MAIN OUTCOME MEASURES: Main outcome measures included, first, characteristics (format and content) of medication safety letters and second, overlap of subject and release date across countries. RESULTS: Of 330 medication safety letters identified, 227 dealt with unique issues relating to medications available in all three countries. Of these 227 letters, 21 (9%) medication problems were the subject of letters released in all three countries; 40 (18%) in two countries and 166 (73%) in only one country. Only 13 (62%) of the 21 letters issued in all three countries were released within 6 months of each other. CONCLUSIONS: Significant discrepancies in both the subject and timing of medication safety letters issued by health authorities in three countries (Canada, the USA and the UK) where medical practice is otherwise comparable, raising questions about why, how and when medication problems are identified and communicated to healthcare providers by the authorities. More rapid communication of medication problems and better alignment between authorities could enhance patient safety. PMID- 30297343 TI - Comparison of simulation debriefs with traditional needs assessment methods: a qualitative exploratory study in a critical care community setting. AB - OBJECTIVE: To better understand the potential of a needs assessment approach using qualitative data from manikin-based and virtual patient simulation debriefing sessions compared with traditional data collection methods (ie, focus groups and interviews). DESIGN: Original data from simulation debrief sessions was compared and contrasted with data from an earlier assessment of critical care needs in a community setting (using focus groups and interviews), thus undertaking secondary analysis of data. Time and cost data were also examined. Debrief sessions were coded using deductive and inductive techniques. Matrices were used to explore the commonalities, differences and emergent findings across the methods. SETTING: Critical care unit in a community hospital setting. RESULTS: Interviews and focus groups yielded 684 and 647 min of audio-recordings, respectively. The manikin-based debrief recordings averaged 22 min (total=130 min) and virtual patient debrief recordings averaged 31 min (total=186 min). The approximate cost for the interviews and focus groups was $13 560, for manikin based simulation debriefs was $4030 and for the virtual patient debriefs was $3475. Fifteen of 20 total themes were common across the simulation debriefs and interview/focus group data. Simulation-specific themes were identified, including fidelity (environment, equipment and psychological) and the multiple roles of the simulation instructor (educative, promoting reflection and assessing needs). CONCLUSIONS: Given current fiscal realities, the dual benefit of being educative and identifying needs is appealing. While simulation is an innovative method to conduct needs assessments, it is important to recognise that there are trade-offs with the selection of methods. PMID- 30297345 TI - Validation of billing code combinations to identify cardiovascular magnetic resonance imaging scans in Ontario, Canada: a retrospective cohort study. AB - OBJECTIVES: Cardiovascular magnetic resonance (CMR) imaging is the gold-standard test for the assessment of heart function. Despite its importance, many jurisdictions lack specific billing codes that can be used to identify patient receipt of CMR in administrative databases, limiting the ability to perform 'big data' CMR studies. Our objective was to identify the optimal billing code combination to identify patients who underwent CMR using administrative data in Ontario. DESIGN: Retrospective cohort study. SETTING: Quaternary care academic referral centre in Ontario, Canada. PARTICIPANTS: We tested all billing code combinations in order to identify the optimal one to determine receipt of CMR. The reference gold standard was a list of all cardiothoracic magnetic resonance scans performed at Sunnybrook Health Sciences Centre between 1 January 2014 and 31 December 2016, verified by chart audit. We assessed the diagnostic performance (accuracy, sensitivity, specificity, positive predictive value and negative predictive value) for all code combinations. RESULTS: Our gold-standard cohort consisted of 2339 thoracic MRIs that were performed at Sunnybrook Health Sciences Centre from 1 January 2014 to 31 December 2016. Of these, 2139 (91.5%) were CMRs and 200 (8.5%) were chest MRIs. We identified the most accurate billing combination for the determination of patient receipt of CMR. This combination resulted in an accuracy of 95.3% (95% CI 94.4% to 96.2%), sensitivity of 97.4% (95% CI 96.6% to 98.1%), specificity of 86.4% (95% CI 83.1% to 89.6%), positive predictive value of 96.9% (95% CI 96.1% to 97.6%) and negative predictive value of 88.4% (95% CI 85.4% to 91.5%). CONCLUSIONS: Our study is the first to verify the ability to accurately identify patient receipt of CMR using administrative data, facilitating more robust population-based CMR studies in the future. PMID- 30297344 TI - Testing the information-motivation-behavioural skills model of diabetes self management among Chinese adults with type 2 diabetes: a protocol of a 3-month follow-up study. AB - INTRODUCTION: Currently, China leads the world in the number of people with diabetes, making it home to a third of the global diabetic population. Persons with diabetes have to carry out 95% of their self-care. As an important component of diabetes care, diabetes self-management (DSM) is defined as everyday behaviours that persons carry out to control diabetes. Consistent findings have been reported that level of compliance to suggested DSM behaviours is not considered optimal among Chinese adults with type 2 diabetes (T2D). The underlying reasons for suboptimal DSM behaviours among Chinese adults are not well known and no conceptual model has been developed to guide DSM interventions in this population. Although the information-motivation-behavioural skills model has been tested among Chinese adults with T2D, some key components of the original model were not tested. In this proposed study protocol, we will refine and test a culturally tailored model of DSM longitudinally among 250 Chinese adults residing in China. METHODS AND ANALYSIS: This is a descriptive, repeated measure study to be conducted at a tertiary hospital in Chengdu, China. A total of 250 adults with T2D will be enrolled and followed for 3 months in this study. Information of multiple domains will be collected, including demographics, diabetes knowledge, health education form, provider-patient communication, health beliefs, social support, diabetes self-efficacy, the medical coping modes, the diabetes self-care, depression, diabetes-dependent quality of life, haemoglobin A1c, blood pressure and blood lipids at baseline and 3-month follow-up. Main analyses comprise linear regression modelling controlling for covariates and structural equation modelling. ETHICS AND DISSEMINATION: Ethical approval has been obtained through the Fourth People's Hospital of Chengdu Research Ethics Committee (study approval number 2017017). We aim to disseminate the findings through international conferences, international peer-reviewed journals and social media. TRIAL REGISTRATION NUMBER: ChiCTR-ROC-17013592. PMID- 30297346 TI - Visibility of tobacco products and advertisement at the point of sale: a systematic audit of retailers in Amsterdam. AB - OBJECTIVES: Visibility of tobacco products at the point of sale (PoS), in settings where open display of tobacco is allowed, is one of the last remaining ways in which the tobacco industry can legally promote their products. The aim of this study was to map the visibility of tobacco products and advertisement both inside and outside retailers, among different types of retailers. SETTING: The study was conducted in two districts in Amsterdam, the Netherlands. PARTICIPANTS: All potential tobacco retailers were visited within the districts, and were mapped using Global Positioning System (GPS) coordinates. INTERVENTION: Observational data was collected for each tobacco retailer using a checklist with characteristics of the internal and external visibility of tobacco products and advertisement. Retailers were categorised into supermarkets, hospitality industry, tobacconists and 'other retailers' (convenience stores, office supply stores, gas stations, drug stores and telephone communication stores). Data were collected in April-May 2017. RESULTS: Eighty-two tobacco retailers were identified. Among all retailers, 52.4% had external and 91.5% internal visibility of tobacco products. Tobacconists had the highest level of internal and external visibility of tobacco products (both 100%), followed by 'other retailers' (100% and 56% respectively) and supermarkets (79% and 47%, respectively). Retailers in the hospitality industry had low external visibility (28%), but high internal visibility (90%), as 83% sold tobacco through vending machines. CONCLUSION: Visibility of tobacco products was high among all types of retailers, including those previous studies show are commonly visited by youth. PMID- 30297347 TI - Protocol for a scoping review on nursing care and the autonomy of disabled persons. AB - INTRODUCTION: Considering the limitations that disabled persons experience, our understanding of caring for these people has evolved over time worldwide. Because nursing care is dependent on the choices made by patients, nurses can play an emancipatory role by empowering patients with disabilities to become the primary agent in their rehabilitation. Objective was to conduct a range analysis protocol proposing the mapping of conceptual elements for a nursing care model based on the autonomy of disabled persons. METHODS AND ANALYSIS: A protocol was developed in corporating insights from recent innovations and applying the scope review method of Arksey and O'Malley as a reference using their scoping review methodology as a guide. For the construction of research guiding question, the patient, intervention, comparison and outcomes strategy was adapted. Considerable research in online databases (14) from 2000 to 2018 will be integrated by bibliographical research. Proceed a consult in the Annals of the Brazilian Congress of Nursing, Brazilian Nursing Association and Portuguese Rehabilitation Nursing Association, as well as professional Portuguese and Brazilian nursing legislation. The entire reference list of the covered studies searched manually to detect considerable additional studies. In addition to these searches, stakeholders, including nurse experts in the rehabilitation field and disabled persons, will be requested and included. ETHICS AND DISSEMINATION: This study does not require ethical approval because it is a review and collection of data on publicly available materials. The results of this research will be published in a relevant journal on the subject of rehabilitation and presented at international scientific events in the area of rehabilitation nursing. Thus, the elaboration of this protocol further maps the gaps and strengthens the concepts capable of presenting strong evidence which assists and supports safer, smarter and more objective care for those living with permanent daily care obligations. PMID- 30297348 TI - LDL-C:HDL-C ratio and common carotid plaque in Xinjiang Uygur obese adults: a cross-sectional study. AB - OBJECTIVE: The aim of this study was to explore the relationship between low density lipoprotein cholesterol:high-density lipoprotein cholesterol (LDL-C:HDL C) ratio and common carotid atherosclerotic plaque (CCAP) among obese adults of Uygur community in Xinjiang, China. DESIGN: A hospital-based cross-sectional study. SETTING: First Affiliated Hospital of Xinjiang Medical University. PARTICIPANTS: A total of 1449 obese adults of Uygur population who were free of coronary artery disease were included in our study from 1 January 2014 to 31 December 2016. METHODOLOGY: Lipid profiles, other routine laboratory parameters and intima-media thickness of the common carotid artery were measured in all participants. Multivariate logistic regression analysis was used to examine the association between LDL-C:HDL-C ratio and CCAP. RESULTS: Four hundred and fifteen (28.64%) participants had CCAP. Participants with CCAP had significantly higher LDL-C:HDL-C ratio compared with those without CCAP (3.21 [2.50, 3.88] vs 2.33 [1.95, 2.97], p<0.001). Multivariate logistic regression analysis showed high LDL C:HDL-C ratio as independent predictor of CCAP after adjusting for conventional cardiovascular risk factors. The top LDL-C:HDL-C ratio quartile (>=3.25) had an OR of 9.355 (95% CI 6.181 to 14.157) compared with the bottom quartile (<2.07) of LDL-C:HDL-C ratio (p<0.001) after adjustment for age, body mass index, smoking, diabetes mellitus and serum level of total cholesterol. CONCLUSION: CCAP is highly prevalent in Uygur obese adults. A high LDL-C:HDL-C ratio is an independent predictor of CCAP. It may help identify obese individuals who are at high risk of CCAP and who may benefit from intensive LDL-lowering therapy. PMID- 30297349 TI - Do changing medical admissions practices in the UK impact on who is admitted? An interrupted time series analysis. AB - INTRODUCTION: Medical admissions must balance two potentially competing missions: to select those who will be successful medical students and clinicians and to increase the diversity of the medical school population and workforce. Many countries address this dilemma by reducing the heavy reliance on prior educational attainment, complementing this with other selection tools. However, evidence to what extent this shift in practice has actually widened access is conflicting. AIM: To examine if changes in medical school selection processes significantly impact on the composition of the student population. DESIGN AND SETTING: Observational study of medical students from 18 UK 5-year medical programmes who took the UK Clinical Aptitude Test from 2007 to 2014; detailed analysis on four schools. PRIMARY OUTCOME: Proportion of admissions to medical school for four target groups (lower socioeconomic classes, non-selective schooling, non-white and male). DATA ANALYSIS: Interrupted time-series framework with segmented regression was used to identify the impact of changes in selection practices in relation to invitation to interview to medical school. Four case study medical schools were used looking at admissions within for the four target groups. RESULTS: There were no obvious changes in the overall proportion of admissions from each target group over the 8-year period, averaging at 3.3% lower socioeconomic group, 51.5% non-selective school, 30.5% non-white and 43.8% male. Each case study school changed their selection practice in decision making for invite to interview during 2007-2014. Yet, this within-school variation made little difference locally, and changes in admission practices did not lead to any discernible change in the demography of those accepted into medical school. CONCLUSION: Although our case schools changed their selection procedures, these changes did not lead to any observable differences in their student populations. Increasing the diversity of medical students, and hence the medical profession, may require different, perhaps more radical, approaches to selection. PMID- 30297350 TI - Examining the risk of depression or self-harm associated with incretin-based therapies used to manage hyperglycaemia in patients with type 2 diabetes: a cohort study using the UK Clinical Practice Research Datalink. AB - OBJECTIVES: To compare population-based incidence rates of new-onset depression or self-harm in patients initiating incretin-based therapies with that of sulfonylureas (SU) and other glucose-lowering agents. DESIGN: Population-based cohort study. SETTING: Patients attending primary care practices registered with the UK-based Clinical Practice Research Datalink (CPRD). PARTICIPANTS: Using the UK-based CPRD, we identified two incretin-based therapies cohorts: (1) dipeptidyl peptidase-4 inhibitor (DPP-4i)-cohort, consisting of new users of DPP-4i and SU and (2) glucagon-like peptide-1 receptor agonists (GLP-1RA)-cohort, consisting of new users of GLP-1RA and SU, between January 2007 and January 2016. Patients with a prior history of depression, self-harm and other serious psychiatric conditions were excluded. MAIN OUTCOME MEASURES: The primary study outcome comprised a composite of new-onset depression or self-harm. Unadjusted and adjusted Cox proportional hazards regression was used to quantify the association between incretin-based therapies and depression or self-harm. Deciles of High-Dimensional Propensity Scores and concurrent number of glucose-lowering agents were used to adjust for potential confounding. RESULTS: We identified new users of 6206 DPP-4i and 22 128 SU in the DPP-4i-cohort, and 501 GLP-1RA and 16 409 SU new users in the GLP-1RA-cohort. The incidence of depression or self-harm was 8.2 vs 11.7 events/1000 person-years in the DPP-4i-cohort and 18.2 vs 13.6 events/1000 person years in the GLP-1RA-cohort for incretin-based therapies versus SU, respectively. Incretin-based therapies were not associated with an increased or decreased incidence of depression or self-harm compared with SU (DPP-4i-cohort: unadjusted HR 0.70, 95% CI 0.51 to 0.96; adjusted HR 0.80, 95% CI 0.57 to 1.13; GLP-1RA cohort: unadjusted HR 1.36, 95% CI 0.72 to 2.58; adjusted HR 1.25, 95% CI 0.63 to 2.50). Consistent results were observed for other glucose-lowering comparators including insulin and thiazolidinediones. CONCLUSIONS: Our findings suggest that the two incretin-based therapies are not associated with an increased or decreased risk of depression or self-harm.

PMID- 30297351 TI - Nutrition and physical performance in older people-effects of marine protein hydrolysates to prevent decline in physical performance: a randomised controlled trial protocol. AB - INTRODUCTION: Age-related loss of muscle mass, muscle strength and muscle function (sarcopenia) leads to a decline in physical performance, loss of independence and reduced quality of life. Nutritional supplements may delay the progression of sarcopenia. The aim of this randomised, double-blinded controlled trial including 100 participants (>=65 years) is to assess the effect of a marine protein hydrolysate (MPH) on sarcopenia-related outcomes like hand grip strength, physical performance or gait speed and to study the associations between physical performance and nutritional intake and status. METHOD AND ANALYSIS: The intervention group (n=50) will receive 3 g of MPH per day in 12 months. The control group (n=50) receive placebo. Assessments of Short Physical Performance Battery (SPPB), hand grip strength, anthropometric measurements, nutritional status as measured by the Mini Nutritional Assessment, dietary intake, supplement use, biomarkers of protein nutrition and vitamin D, and health-related quality of life (EQ-5D), will be performed at baseline and after 6 and 12 months of intervention. Linear mixed models will be estimated to assess the effect of MPH on SPPB, hand grip strength and quality of life, as well as associations between physical performance and nutrition. ETHICS AND DISSEMINATION: The study has been approved by the Regional Committee in Ethics in Medical Research in Mid-Norway in September 2016 with the registration ID 2016/1152. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media, broadcast media and print media. TRIAL REGISTRATION NUMBER: NCT02890290. PMID- 30297352 TI - Efficacy of photobiomodulation on oral lichen planus: a protocol study for a double-blind, randomised controlled clinical trial. AB - INTRODUCTION: Oral lichen planus (OLP) is an idiopathic chronic mucocutaneous disease with a wide range of clinical manifestations, including white reticular patches, erosive/ulcerative and atrophic lesions, both associated with intense symptomatology. Topical corticosteroids are commonly used as standard therapy. However, patients frequently present relapses after the discontinuation of treatment as well as developing resistance to corticosteroid therapy. Photobiomodulation (PBM) has been shown to be a potential therapeutic tool to treat inflammatory disorders, including OLP. The aim of this study was to compare the efficacy of PBM (660 nm) with corticosteroid therapy with clobetasol propionate 0.05% for the treatment of OLP. METHODS AND ANALYSIS: Forty-four patients with symptomatic and histopathological diagnosis of OLP will be randomised into two experimental groups in a double-blind manner: control group (n=22): clobetasol propionate 0.05%+placebo PBM, and experimental group (n=22): PBM (lambda=660 nm, power 100 mW, radiant exposure: 177 J/cm2 and 0.5J per point)+placebo gel. Laser will be applied 2*/week for 1 month and clobetasol propionate three times a day for 30 days and the same for placebo treatments. The primary variable (pain) and the secondary variables (clinical score, evaluation of functional scores, clinical resolution, OLP recurrence, quality of life and anxiety and depression) will be evaluated at the baseline, once a week during treatment (depending on the variables) and after 30 days and 60 days of follow up. Pain will be evaluated using visual analogue scale and clinical characteristics will be scored using the Thongprasom Index. The quality of life and anxiety and depression will be evaluated by Oral Health Impact Profile-14 questionnaire and by Hospital Anxiety and Depression Scale for anxiety scale, respectively. The serum and salivary levels of interleukin (IL)-6, IL-10, IL 1beta, INF-gamma and tumour necrosis factor-alpha will be evaluated by ELISA at baseline and at the end of treatment. ETHICS AND DISSEMINATION: This protocol was approved (#2.375.410) by the Nove de Julho University (UNINOVE) Research Ethics Committee. The data gathered using this protocol will be published in a peer reviewed journal. TRIAL REGISTRATION NUMBER: NCT03320460. PMID- 30297355 TI - Cochrane centre based in Spain calls for investigation into director's dismissal. PMID- 30297353 TI - Relationship between right-to-left shunt and migraine in patients with epilepsy: a single-centre, cross-sectional study in China. AB - OBJECTIVES: To investigate the relationship between right-to-left shunt and migraine to account for the unexplained high prevalence of migraine in patients with epilepsy. DESIGN: This is a cross-sectional study. The diagnosis and interview process of patients with migraine was based on the International Classification of Headache Disorders-3 beta in patients with epilepsy. Participants underwent transthoracic echocardiography (TTE) with contrast medium to identify right-to-left shunt. The highest number of microbubbles were recorded in the left atrium before the complete microbubble outflow of the right atrium. A moderate-to-large shunt was defined as the presence of 10 or more microbubbles. SETTING: A single-centre, cross-sectional study in China, 2015-2017. PARTICIPANTS: Patients with epilepsy. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome measures were the prevalence of migraine, the prevalence of right to-left shunt in patients with migraine and those without migraine, and the prevalence of migraine in different degrees of shunting. RESULTS: Three hundred thirty-nine participants with epilepsy who completed TTE were included in the analysis. The overall prevalence of migraine was 23.0%. One-third of the migraineurs had mild right-to-left shunt and one-fifth of the migraineurs had moderate-to-large right-to-left shunt. Patients with mild shunt did not have a higher prevalence of migraine than those without shunt (26.3% vs 18.1%, p=0.102); however, a higher prevalence of migraine was found in patients with moderate-to large shunt (39.0% vs 18.1%, OR=2.90, 95% CI=1.41 to 5.98, p=0.003). Patients with migraine and patients without migraine had similar prevalence of mild shunt; however, patients with migraine had more moderate-to-large shunt (20.5% vs 9.6%, p=0.002). Right-to-left shunt and female were factors predicting migraine prevalence. CONCLUSIONS: One-fifth of migraineurs were correlated with moderate to-large right-to-left shunt which could be an underlying cause of migraine in epilepsy. PMID- 30297356 TI - The Expanding Molecular Genetics Tool Kit in Chlamydia. AB - Chlamydia has emerged as an important model system for the study of host pathogen interactions, in part due to a resurgence in the development of tools for its molecular genetic manipulation. An additional tool, published by Keb et al. (G. Keb, R. Hayman, and K. A. Fields, J. Bacteriol. 200:e00479-18, 2018, https://doi.org/10.1128/JB.00479-18), now allows for custom genetic engineering of genomic regions that were traditionally recalcitrant to genetic manipulation, such as genes within operons. This new method will be an essential instrument for the elucidation of Chlamydia-host interactions. PMID- 30297357 TI - Thermal and Nutritional Regulation of Ribosome Hibernation in Staphylococcus aureus. AB - The translationally silent 100S ribosome is a poorly understood form of the dimeric 70S complex that is ubiquitously found in all bacterial phyla. The elimination of the hibernating 100S ribosome leads to translational derepression, ribosome instability, antibiotic sensitivity, and biofilm defects in some bacteria. In Firmicutes, such as the opportunistic pathogen Staphylococcus aureus, a 190-amino acid protein called hibernating-promoting factor (HPF) dimerizes and conjoins two 70S ribosomes through a direct interaction between the HPF homodimer, with each HPF monomer tethered on an individual 70S complex. While the formation of the 100S ribosome in gammaproteobacteria and cyanobacteria is exclusively induced during postexponential growth phase and darkness, respectively, the 100S ribosomes in Firmicutes are constitutively produced from the lag-logarithmic phase through the post-stationary phase. Very little is known about the regulatory pathways that control hpf expression and 100S ribosome abundance. Here, we show that a general stress response (GSR) sigma factor (SigB) and a GTP-sensing transcription factor (CodY) integrate nutrient and thermal signals to regulate hpf synthesis in S. aureus, resulting in an enhanced virulence of the pathogen in a mouse model of septicemic infection. CodY dependent regulation of hpf is strain specific. An epistasis analysis further demonstrated that CodY functions upstream of the GSR pathway in a condition dependent manner. The results reveal an important link between S. aureus stress physiology, ribosome metabolism, and infection biology.IMPORTANCE The dimerization of 70S ribosomes (100S complex) plays an important role in translational regulation and infectivity of the major human pathogen Staphylococcus aureus Although the dimerizing factor HPF has been characterized biochemically, the pathways that regulate 100S ribosome abundance remain elusive. We identified a metabolite- and nutrient-sensing transcription factor, CodY, that serves both as an activator and a repressor of hpf expression in nutrient- and temperature-dependent manners. Furthermore, CodY-mediated activation of hpf masks a secondary hpf transcript derived from a general stress response SigB promoter. CodY and SigB regulate a repertoire of virulence genes. The unexpected link between ribosome homeostasis and the two master virulence regulators provides new opportunities for alternative druggable sites. PMID- 30297359 TI - DNA Damage, Liver Injury, and Tumorigenesis: Consequences of DDX3X Loss. AB - The pleiotropic roles of DEAD-box helicase 3, X-linked (DDX3X), including its functions in transcriptional and translational regulation, chromosome segregation, DNA damage, and cell growth control, have highlighted the association between DDX3X and tumorigenesis. However, mRNA transcripts and protein levels of DDX3X in patient specimens have shown the controversial correlations of DDX3X with hepatocellular carcinoma (HCC) prevalence. In this study, generation of hepatocyte-specific Ddx3x-knockout mice revealed that loss of Ddx3x facilitates liver tumorigenesis. Loss of Ddx3x led to profound ductular reactions, cell apoptosis, and compensatory proliferation in female mutants at 6 weeks of age. The sustained phosphorylation of histone H2AX (gammaH2AX) and significant accumulation of DNA single-strand breaks and double-strand breaks in liver indicated that the replicative stress occurred in female mutants. Further chromatin immunoprecipitation analyses demonstrated that DDX3X bound to promoter regions and regulated the expression of DNA repair factors, DDB2 and XPA, to maintain genome stability. Loss of Ddx3x led to decreased levels of DNA repair factors, which contributed to an accumulation of unrepaired DNA damage, replication stress, and eventually, spontaneous liver tumors and DEN-induced HCCs in Alb-Cre/+;Ddx3xflox/flox mice.Implications: These data identify an important role of DDX3X in the regulation of DNA damage repair to protect against replication stress in liver and HCC development and progression.

AB - KRAS-driven lung cancers frequently inactivate TP53 and/or STK11/LKB1, defining tumor subclasses with emerging clinical relevance. Specifically, KRAS-LKB1 (KL) mutant lung cancers are particularly aggressive, lack PD-L1, and respond poorly to immune checkpoint blockade (ICB). The mechanistic basis for this impaired immunogenicity, despite the overall high mutational load of KRAS mutant lung cancers, remains obscure. Here we report that LKB1 loss results in marked silencing of STING expression and insensitivity to cytoplasmic double strand DNA (dsDNA) sensing. This effect is mediated at least in part by hyperactivation of DNMT1 and EZH2 activity related to elevated S-adenylmethionine (SAM) levels, and reinforced by DNMT1 upregulation. Ectopic expression of STING in KL cells engages IRF3 and STAT1 signaling downstream of TBK1 and impairs cellular fitness, due to the pathologic accumulation of cytoplasmic mitochondrial dsDNA associated with mitochondrial dysfunction. Thus, silencing of STING avoids these negative consequences of LKB1 inactivation, while facilitating immune escape. PMID- 30297360 TI - Hsp70 binds to the androgen receptor N-terminal domain and modulates the receptor function in prostate cancer cells. AB - The androgen receptor (AR) is a key driver and therapeutic target in androgen sensitive prostate cancer, castration resistant prostate cancer (CRPC), and CRPC resistant to abiraterone and enzalutamide, two second generation inhibitors of AR signaling. Since current AR inhibitors target a functioning C-terminal ligand binding domain (LBD), the identification and characterization of co-factors interacting with the N-terminal domain (NTD) of AR may lead to new approaches to target AR signaling in CRPC. Using a pulldown approach coupled with proteomics, we have identified Hsp70 as a co-factor for the NTD of AR in prostate cancer cells. Hsp70 inhibition using siRNA or small molecules indicated that Hsp70 played an important role in the expression and transactivation of endogenous AR. Prostate specific antigen (PSA) promoter/enhancer-driven luciferase assays showed that Hsp70 was also required for transactivation of AR mutant lacking LBD. Furthermore, clonogenic assays showed that an Hsp70 inhibitor, either alone or in synergy with enzalutamide, can inhibit the proliferation of 22Rv1, a widely-used enzalutamide-resistant CRPC prostate cancer cell line. These findings suggest that Hsp70 is a potential therapeutic target for the treatment of enzalutamide resistant CRPC. PMID- 30297361 TI - Oleanolic acid inhibits epithelial-mesenchymal transition of hepatocellular carcinoma by promoting iNOS dimerization. AB - Oleanolic acid (OA) exhibits extensive pharmacological activities and takes significant anti-tumor effects. Its pharmacological mechanism, however, are still remained to be further clarified. In this study, we demonstrated that OA attenuated the migration and invasion abilities, resulting in the suppression of the EMT process in liver cancer cells, and inhibited the tumor growth of the PLC bearing mice. We further proved that inducible nitric oxide synthase (iNOS) may be the potential target of OA. We confirmed that OA could promote the dimerization of iNOS, activating it and subsequently increasing the production of nitric oxide (NO). Further experiments indicated that OA promoted the nitration of specific proteins and consequently suppressed their epithelial-mesenchymal transition (EMT)-related biological functions. Furthermore, it has been confirmed that OA enhanced the anti-tumor effects of regorafenib in liver cancer treatment. These results deepened our understanding of the pharmacological mechanism of the antitumor effect OA, and the importance of NOS as a therapeutic target for liver cancer treatment. PMID- 30297362 TI - Role of Capsule in Resistance to Disinfectants, Host Antimicrobials, and Desiccation in Acinetobacter baumannii. AB - Acinetobacter baumannii strain AB5075 forms two cell types distinguished by their opaque (VIR-O) or translucent (AV-T) colonies. VIR-O cells possess a thicker capsule and are more resistant to a variety of stressors than AV-T cells. However, the direct role of the capsule in these stressors was unknown. This study demonstrates that the capsule is required for resistance to disinfectants, lysozyme, and desiccation in Acinetobacter baumannii In addition, the capsule is required for survival in a mouse lung model of infection. PMID- 30297363 TI - Polymorphism of Polymeric Amino Acid Regions in Fungal Proteins and Correlation with Altered Echinocandin and Azole Susceptibility. AB - Polymorphism of polymeric amino acid (polyX) regions within fungal proteins represents a potential mechanism for rapid genotypic adaptation to environmental pressures, including antifungal exposure. Polyglutamine (polyQ) was the most abundant repeat in the proteomes of 8 diverse fungal species and was preferentially found in regulatory proteins. In Candida glabrata, polyX polymorphisms were characterized in 36 proteins implicated in azole or echinocandin susceptibility. General transcriptional repressor Tup1A exhibited Q44/Q45 polymorphism, and Hog1 signaling component Ssk2 exhibited N44/N45 polymorphism in phylogenetically matched echinocandin- and azole susceptible/resistant strains, respectively. PMID- 30297364 TI - Two Regulators, PA3898 and PA2100, Modulate the Pseudomonas aeruginosa Multidrug Resistance MexAB-OprM and EmrAB Efflux Pumps and Biofilm Formation. AB - It is generally believed that the Pseudomonas aeruginosa biofilm matrix itself acts as a molecular sieve or sink that contributes to significant levels of drug resistance, but it is becoming more apparent that multidrug efflux pumps induced during biofilm growth significantly enhance resistance levels. We present here a novel transcriptional regulator, PA3898, which controls biofilm formation and multidrug efflux pumps in P. aeruginosa A mutant of this regulator significantly reduced the ability of P. aeruginosa to produce biofilm in vitro and affected its in vivo fitness and pathogenesis in Drosophila melanogaster and BALB/c mouse lung infection models. Transcriptome analysis revealed that PA3898 modulates essential virulence genes/pathways, including multidrug efflux pumps and phenazine biosynthesis. Chromatin immunoprecipitation sequencing (ChIP-seq) identified its DNA binding sequences and confirmed that PA3898 directly interacts with promoter regions of four genes/operons, two of which are mexAB-oprM and phz2 Coimmunoprecipitation revealed a regulatory partner of PA3898 as PA2100, and both are required for binding to DNA in electrophoretic mobility shift assays. PA3898 and PA2100 were given the names MdrR1 and MdrR2, respectively, as novel repressors of the mexAB-oprM multidrug efflux operon and activators for another multidrug efflux pump, EmrAB. The interaction between MdrR1 and MdrR2 at the promoter regions of their regulons was further characterized via localized surface plasmon resonance and DNA footprinting. These regulators directly repress the mexAB-oprM operon, independent of its well-established MexR regulator. Mutants of mdrR1 and mdrR2 caused increased resistance to multiple antibiotics in P. aeruginosa, validating the significance of these newly discovered regulators. PMID- 30297365 TI - Breaking the Vicious Cycle of Antibiotic Killing and Regrowth of Biofilm-Residing Pseudomonas aeruginosa. AB - Biofilm-residing bacteria embedded in an extracellular matrix are protected from diverse physicochemical insults. In addition to the general recalcitrance of biofilm bacteria, high bacterial loads in biofilm-associated infections significantly diminish the efficacy of antimicrobials due to a low per-cell antibiotic concentration. Accordingly, present antimicrobial treatment protocols that have been established to serve the eradication of acute infections fail to clear biofilm-associated chronic infections. In the present study, we applied automated confocal microscopy on Pseudomonas aeruginosa to monitor dynamic killing of biofilm-grown bacteria by tobramycin and colistin in real time. We revealed that the time required for surviving bacteria to repopulate the biofilm could be taken as a measure for effectiveness of the antimicrobial treatment. It depends on the (i) nature and concentration of the antibiotic, (ii) duration of antibiotic treatment, (iii) application as monotherapy or combination therapy, and (iv) interval of drug administration. The vicious cycle of killing and repopulation of biofilm bacteria could also be broken in an in vivo model system by applying successive antibiotic dosages at intervals that do not allow full reconstitution of the biofilm communities. Treatment regimens that consider the important aspects of antimicrobial killing kinetics bear the potential to improve control of biofilm regrowth. This is an important and underestimated factor that is bound to ensure sustainable treatment success of chronic infections. PMID- 30297366 TI - Competitive Fitness of Essential Gene Knockdowns Reveals a Broad-Spectrum Antibacterial Inhibitor of the Cell Division Protein FtsZ. AB - To streamline the elucidation of antibacterial compounds' mechanism of action, comprehensive high-throughput assays interrogating multiple putative targets are necessary. However, current chemogenomic approaches for antibiotic target identification have not fully utilized the multiplexing potential of next generation sequencing. Here, we used Illumina sequencing of transposon insertions to track the competitive fitness of a Burkholderia cenocepacia library containing essential gene knockdowns. Using this method, we characterized a novel benzothiadiazole derivative, 10126109 (C109), with antibacterial activity against B. cenocepacia, for which whole-genome sequencing of low-frequency spontaneous drug-resistant mutants had failed to identify the drug target. By combining the identification of hypersusceptible mutants and morphology screening, we show that C109 targets cell division. Furthermore, fluorescence microscopy of bacteria harboring green fluorescent protein (GFP) cell division protein fusions revealed that C109 prevents divisome formation by altering the localization of the essential cell division protein FtsZ. In agreement with this, C109 inhibited both the GTPase and polymerization activities of purified B. cenocepacia FtsZ. C109 displayed antibacterial activity against Gram-positive and Gram-negative cystic fibrosis pathogens, including Mycobacterium abscessus C109 effectively cleared B. cenocepacia infection in the Caenorhabditis elegans model and exhibited additive interactions with clinically relevant antibiotics. Hence, C109 is an enticing candidate for further drug development. PMID- 30297368 TI - Amixicile Reduces Severity of Cryptosporidiosis but Does Not Have In Vitro Activity against Cryptosporidium. AB - Cryptosporidium species cause significant morbidity in malnourished children. Nitazoxanide (NTZ) is the only approved treatment for cryptosporidiosis, but NTZ has diminished effectiveness during malnutrition. Here, we show that amixicile, a highly selective water-soluble derivative of NTZ diminishes Cryptosporidium infection severity in a malnourished mouse model despite a lack of direct anticryptosporidial activity. We suggest that amixicile, by tamping down anaerobes associated with intestinal inflammation, reverses weight loss and indirectly mitigates infection-associated pathology. PMID- 30297367 TI - Lipase Precursor-Like Protein Promotes Miltefosine Tolerance in Leishmania donovani by Enhancing Parasite Infectivity and Eliciting Anti-inflammatory Responses in Host Macrophages. AB - The oral drug miltefosine (MIL) was introduced in the Indian subcontinent in the year 2002 for the treatment of visceral leishmaniasis (VL). However, recent reports on its declining efficacy and increasing relapse rates pose a serious concern. An understanding of the factors contributing to MIL tolerance in Leishmania parasites is critical. In the present study, we assessed the role of the lipase precursor-like protein (Lip) in conferring tolerance to miltefosine by episomally overexpressing Lip in Leishmania donovani (LdLip++). We observed a significant increase (~3-fold) in the MIL 50% inhibitory concentration (IC50) at both the promastigote (3.90 +/- 0.68 uM; P < 0.05) and intracellular amastigote (9.10 +/- 0.60 uM; P < 0.05) stages compared to the wild-type counterpart (LdNeo) (MIL IC50s of 1.49 +/- 0.20 uM at the promastigote stage and 3.95 +/- 0.45 uM at the amastigote stage). LdLip++ parasites exhibited significantly (P < 0.05) increased infectivity to host macrophages and increased metacyclogenesis and tolerance to MIL-induced oxidative stress. The susceptibility of LdLip++ to other antileishmanial drugs (sodium antimony gluconate and amphotericin B) remained unchanged. In comparison to LdNeo, the LdLip++ parasites elicited high host interleukin-10 (IL-10) cytokine expression levels (1.6-fold; P < 0.05) with reduced expression of the cytokine tumor necrosis factor alpha (TNF-alpha) (1.5 fold; P < 0.05), leading to a significantly (P < 0.01) increased ratio of IL 10/TNF-alpha. The above-described findings suggest a role of lipase precursor like protein in conferring tolerance to the oral antileishmanial drug MIL in L. donovani parasites. PMID- 30297369 TI - Effects of Food and Omeprazole on a Novel Formulation of Super Bioavailability Itraconazole in Healthy Subjects. AB - To address the limited bioavailability and intolerance of the conventional itraconazole (ITZ) formulations, a new formulation labeled super bioavailability (SUBA) itraconazole has been developed; however, the specific effects of food and gastric pH are unknown. This study evaluated the pharmacokinetic profile of SUBA itraconazole under fasting and fed conditions, as well as with the concomitant administration of a proton pump inhibitor. First, the effect of food was assessed in an open-label, randomized, crossover bioavailability study of 65-mg SUBA itraconazole capsules (2 65-mg capsules twice a day) in healthy adults (n = 20) under fasting and fed conditions to steady-state levels. Second, an open-label, two-treatment, fixed-sequence comparative bioavailability study in healthy adults (n = 28) under fasted conditions compared the pharmacokinetics of a single oral dose of SUBA itraconazole capsules (2 65-mg capsules/day) with and without coadministration of daily omeprazole delayed-release capsules (1 40-mg capsule/day) under steady-state conditions. In the fed and fasted states, SUBA itraconazole demonstrated similar concentrations at the end of the dosing interval, with modestly lower total and peak ITZ exposure being shown when it was administered under fed conditions than when it was administered in the fasted state, with fed state/fasted state ratios of 78.09% (90% confidence interval [CI], 74.49 to 81.86%) for the area under the concentration-time curve over the dosing interval (14,183.2 versus 18,479.8 ng . h/ml), 73.05% (90% CI, 69.01 to 77.33%) for the maximum concentration at steady state (1,519.1 versus 2,085.2 ng/ml), and 91.53% (90% CI, 86.41 to 96.96%) for the trough concentration (1,071.5 versus 1,218.5 ng/ml) being found. When dosed concomitantly with omeprazole, there was a 22% increase in the total plasma exposure of ITZ, as measured by the area under the concentration-time curve from time zero to infinity (P = 0.0069), and a 31% increase in the peak plasma exposure of ITZ, as measured by the maximum concentration (P = 0.0083). PMID- 30297370 TI - Molecular Basis of the Leishmanicidal Activity of the Antidepressant Sertraline as a Drug Repurposing Candidate. AB - Drug repurposing affords the implementation of new treatments at a moderate cost and under a faster time-scale. Most of the clinical drugs against Leishmania share this origin. The antidepressant sertraline has been successfully assayed in a murine model of visceral leishmaniasis. Nevertheless, sertraline targets in Leishmania were poorly defined. In order to get a detailed insight into the leishmanicidal mechanism of sertraline on Leishmania infantum, unbiased multiplatform metabolomics and transmission electron microscopy were combined with a focused insight into the sertraline effects on the bioenergetics metabolism of the parasite. Sertraline induced respiration uncoupling, a significant decrease of intracellular ATP level, and oxidative stress in L. infantum promastigotes. Metabolomics evidenced an extended metabolic disarray caused by sertraline. This encompasses a remarkable variation of the levels of thiol-redox and polyamine biosynthetic intermediates, as well as a shortage of intracellular amino acids used as metabolic fuel by Leishmania Sertraline killed Leishmania through a multitarget mechanism of action, tackling essential metabolic pathways of the parasite. As such, sertraline is a valuable candidate for visceral leishmaniasis treatment under a drug repurposing strategy. PMID- 30297371 TI - Unilateral leg swelling in an infant.

PMID- 30297373 TI - Population Assessment of Tobacco and Health (PATH) reliability and validity study: selected reliability and validity estimates. AB - INTRODUCTION: This paper reports a study done to estimate the reliability and validity of answers to the Youth and Adult questionnaires of the Population Assessment of Tobacco and Health (PATH) Study. METHODS: 407 adults and 117 youth respondents completed the wave 4 (2016-2017) PATH Study interview twice, 6-24 days apart. The reinterview data were used to estimate the reliability of answers to the questionnaire. Kappa statistics, gross discrepancy rates and correlations between answers to the initial interview and the reinterview were used to measure reliability. We examined every item in the questionnaire for which there were at least 100 observations. After the reinterview, most respondents provided a saliva sample that allowed us to assess the accuracy of their answers to the tobacco use questions. RESULTS: There was generally a very high level of agreement between answers in the interview and reinterview. On the key current tobacco use items, the average kappa (the agreement rate adjusted for chance agreement) was 0.79 for adult respondents (age 18 or older). Youth respondents exhibited equally high levels of agreement across interviews. The items on current tobacco use also exhibited high levels of agreement with saliva test results (kappa=0.72). Rating scale items showed lower levels of exact agreement across interviews but the answers were generally within one scale point or category. CONCLUSIONS: The PATH Study questions were developed using a careful protocol and the results indicate the answers provide reliable and valid information about tobacco use.

AB - Ric-8A is a pleiotropic guanine nucleotide exchange factor involved in the activation of various heterotrimeric G-protein pathways during adulthood and early development. Here, we sought to determine the downstream effectors of Ric 8A during the migration of the vertebrate cranial neural crest (NC) cells. We show that the Galpha13 knockdown phenocopies the Ric-8A morphant condition, causing actin cytoskeleton alteration, protrusion instability, and a strong reduction in the number and dynamics of focal adhesions. In addition, the overexpression of Galpha13 is sufficient to rescue Ric-8A-depleted cells. Ric-8A and Galpha13 physically interact and colocalize in protrusions of the cells leading edge. The focal adhesion kinase FAK colocalizes and interacts with the endogenous Galpha13, and a constitutively active form of Src efficiently rescues the Galpha13 morphant phenotype in NC cells. We propose that Ric-8A-mediated Galpha13 signalling is required for proper cranial NC cell migration by regulating focal adhesion dynamics and protrusion formation.

AB - BACKGROUND: Quality improvement (QI) campaigns appear to increase use of evidence based practices, but their effect on health outcomes is less well studied. OBJECTIVE: To assess the effect of a multistate QI campaign (Project JOINTS, Joining Organizations IN Tackling SSIs) that used the Institute for Healthcare Improvement's Rapid Spread Network to promote adoption of evidence-based surgical site infection (SSI) prevention practices. METHODS: We analysed rates of SSI among Medicare beneficiaries undergoing hip and knee arthroplasty during preintervention (May 2010 to April 2011) and postintervention (November 2011 to September 2013) periods in five states included in a multistate trial of the Project JOINTS campaign and five matched comparison states. We used generalised linear mixed effects models and a difference-in-differences approach to estimate changes in SSI outcomes. RESULTS: 125 070 patients underwent hip arthroplasty in 405 hospitals in intervention states, compared with 131 787 in 525 hospitals in comparison states. 170 663 patients underwent knee arthroplasty in 397 hospitals in intervention states, compared with 196 064 in 518 hospitals in comparison states. After the campaign, patients in intervention states had a 15% lower odds of developing hip arthroplasty SSIs (OR=0.85, 95% CI 0.75 to 0.96, p=0.01) and a 12% lower odds of knee arthroplasty SSIs than patients in comparison states (OR=0.88, 95% CI 0.78 to 0.99, p=0.04). CONCLUSIONS: A larger reduction of SSI rates following hip and knee arthroplasty was shown in intervention states than in matched control states. PMID- 30297376 TI - Mortality alerts, actions taken and declining mortality: true effect or regression to the mean? PMID- 30297377 TI - National hospital mortality surveillance system: a descriptive analysis. AB - OBJECTIVE: To provide a description of the Imperial College Mortality Surveillance System and subsequent investigations by the Care Quality Commission (CQC) in National Health Service (NHS) hospitals receiving mortality alerts. BACKGROUND: The mortality surveillance system has generated monthly mortality alerts since 2007, on 122 individual diagnosis and surgical procedure groups, using routinely collected hospital administrative data for all English acute NHS hospital trusts. The CQC, the English national regulator, is notified of each alert. This study describes the findings of CQC investigations of alerting trusts. METHODS: We carried out (1) a descriptive analysis of alerts (2007-2016) and (2) an audit of CQC investigations in a subset of alerts (2011-2013). RESULTS: Between April 2007 and October 2016, 860 alerts were generated and 76% (654 alerts) were sent to trusts. Alert volumes varied over time (range: 40-101). Septicaemia (except in labour) was the most commonly alerting group (11.5% alerts sent). We reviewed CQC communications in a subset of 204 alerts from 96 trusts. The CQC investigated 75% (154/204) of alerts. In 90% of these pursued alerts, trusts returned evidence of local case note reviews (140/154). These reviews found areas of care that could be improved in 69% (106/154) of alerts. In 25% (38/154) trusts considered that identified failings in care could have impacted on patient outcomes. The CQC investigations resulted in full trust action plans in 77% (118/154) of all pursued alerts. CONCLUSION: The mortality surveillance system has generated a large number of alerts since 2007. Quality of care problems were found in 69% of alerts with CQC investigations, and one in four trusts reported that failings in care may have an impact on patient outcomes. Identifying whether mortality alerts are the most efficient means to highlight areas of substandard care will require further investigation.

PMID- 30297382 TI - A European Whitefish Linkage Map and Its Implications for Understanding Genome Wide Synteny Between Salmonids Following Whole Genome Duplication. AB - Genomic datasets continue to increase in number due to the ease of production for a wider selection of species including non-model organisms. For many of these species, especially those with large or polyploid genomes, highly contiguous and well-annotated genomes are still rare due to the complexity and cost involved in their assembly. As a result, a common starting point for genomic work in non model species is the production of a linkage map. Dense linkage maps facilitate the analysis of genomic data in a variety of ways, from broad scale observations regarding genome structure e.g. chromosome number and type or sex-related structural differences, to fine scale patterns e.g. recombination rate variation and co-localization of differentiated regions. Here we present both sex-averaged and sex-specific linkage maps for Coregonus sp. "Albock", a member of the European whitefish lineage (C. lavaretus spp. complex), containing 5395 single nucleotide polymorphism (SNP) loci across 40 linkage groups to facilitate future investigation into the genomic basis of whitefish adaptation and speciation. The map was produced using restriction-site associated digestion (RAD) sequencing data from two wild-caught parents and 156 F1 offspring. We discuss the differences between our sex-averaged and sex-specific maps and identify genome wide synteny between C. sp. "Albock" and Atlantic Salmon (Salmo salar), which have diverged following the salmonid-specific whole genome duplication. Our analysis confirms that many patterns of synteny observed between Atlantic Salmon and Oncorhynchus and Salvelinus species are also shared by members of the Coregoninae subfamily. We also show that regions known for their species-specific rediploidization history can pose challenges for synteny identification since these regions have diverged independently in each salmonid species following the salmonid-specific whole genome duplication. The European whitefish map provided here will enable future studies to understand the distribution of loci of interest, e.g. FST outliers, along the whitefish genome as well as assisting with the de novo assembly of a whitefish reference genome. PMID- 30297383 TI - The Caenorhabditis elegans Oxidative Stress Response Requires the NHR-49 Transcription Factor. AB - The overproduction of reactive oxygen species (ROS) in cells can lead to the development of diseases associated with aging. We have previously shown that C. elegans BRAP-2 (Brca-1 associated binding protein 2) regulates phase II detoxification genes such as gst-4, by increasing SKN-1 activity. Previously, a transcription factor (TF) RNAi screen was conducted to identify potential activators that are required to induce gst-4 expression in brap-2(ok1492) mutants. The lipid metabolism regulator NHR-49/HNF4 was among 18 TFs identified. Here, we show that knockdown of nhr-49 suppresses the activation of gst-4 caused by brap-2 inactivation and that gain-of-function alleles of nhr-49 promote gst-4 expression. We also demonstrate that nhr-49 and its cofactor mdt-15 are required to express phase II detoxification enzymes upon exposure to chemicals that induce oxidative stress. Furthermore, we show that NHR-49 and MDT-15 enhance expression of skn-1a/c These findings identify a novel role for NHR-49 in ROS detoxification by regulating expression of SKN-1C and phase II detoxification genes. PMID- 30297384 TI - Clinical Benefit to an Aurora A Kinase Inhibitor in a Patient with Metastatic Integrase Interactor 1-Deficient Carcinoma. AB - : Integrase interactor 1 (INI-1)-deficient carcinoma is a rare cancer characterized by the loss of the SWItch/Sucrose Non-Fermentable-related matrix associated actin-dependent regulator of chromatin subfamily B member 1 gene (SMARCB1) and tends to follow an aggressive clinical course. There is no currently available standard therapy option, although a few promising treatment strategies, including enhancer of zeste homolog 2 (EZH2) inhibition, are under active investigation. This report describes a 30-year-old woman with INI-1 deficient carcinoma who progressed on combination chemotherapy and an EZH2 inhibitor. Next-generation-sequencing-based targeted cancer-related gene assay confirmed SMARCB1 loss and revealed other mutations in breast cancer 1 gene and checkpoint kinase 2 gene, which may have impacted her clinical course. After discussion at the molecular tumor board, she was offered alisertib, an aurora A kinase inhibitor, on a single-patient expanded-use program and achieved prolonged disease stabilization. Aurora A kinase inhibition may have an important role in the management of patients with INI-1-deficient tumors, warranting further evaluation in clinical studies. KEY POINTS: Loss of the SWItch/Sucrose Non Fermentable-related matrix-associated actin-dependent regulator of chromatin subfamily B member 1 gene (SMARCB1), which encodes integrase interactor 1 (INI 1), is associated with various mesenchymal malignancies, but a few carcinomas with rhabdoid features have been recently described as a distinct entity.INI-1 deficient carcinoma can be very aggressive, and there is no known treatment option available.There are encouraging preliminary data with an enhancer of zeste homolog 2 inhibitor, tazematostat, in INI-1-deficient malignancies, including INI 1-deficient carcinomas.Loss of INI-1 can activate aurora A kinase (AurkA), and inhibition of AurkA by alisertib could be a viable option and warrants further investigation in this cancer.Clinical genomic profiling can confirm diagnosis of molecularly defined malignancy and provide insights on therapeutic options. PMID- 30297386 TI - Indirect Evaluation of Bone Saturation with Zoledronic Acid After Long-Term Dosing. AB - BACKGROUND: Zoledronic acid (ZA), a potent bisphosphonate used for treatment of bone metastasis, has high bone affinity. This post hoc analysis evaluated the effects of long-term treatment and reduction in dosing frequency of ZA on bone saturation. MATERIALS AND METHODS: Pharmacokinetic data from three independent studies, OPTIMIZE-2 (patients receiving >=9 doses of bisphosphonates) and two phase I studies, CZOL4460503 and CZOL4460506 (patients who were bisphosphonate naive/bisphosphonate free for >=1 year after previous dosing), were pooled. Serial urine and plasma samples were used as surrogate markers to determine ZA plasma area under the curve (AUC) over 6 hours (AUC0-6h) and dose excreted in urine over 6 hours (urine0-6h). Potential relationships between the number of years for which patients had been treated previously at time of study entry and AUC0-6h or urine0-6h were analyzed graphically. RESULTS: Creatinine clearances for patients were similar across the three studies and at all time points analyzed. The levels of AUC0-6h ZA in plasma at week 0 in every (q) 4 and q12 weekly arms of OPTIMIZE-2 were 0.366 h * mg/L and 0.397 h * mg/L compared with 0.345 h * mg/L and 0.356 h * mg/L in CZOL4460503 and CZOL4460506, respectively. In OPTIMIZE-2, the AUC0-6h ZA plasma levels were the same (0.428 h * mg/L) at week 36 in both q4 and q12 arms. The levels of ZA urine0-6h at week 36 in OPTIMIZE-2 (q4 and q12 week arms), CZOL4460503, and CZOL4460506 were 36.6%, 30.8%, 26.5%, and 27.3%, respectively. CONCLUSION: Long-term ZA treatment may not impact bone saturation, and ZA dosing frequency does not seem to influence drug retention rates. IMPLICATIONS FOR PRACTICE: Zoledronic acid (ZA), used along with standard antineoplastic therapy to treat bone metastases associated with solid tumors and multiple myeloma, requires frequent (every 3-4 or every 12 weeks) long term administration. This may result in bone saturation and subsequently lead to a higher risk of adverse events such as osteonecrosis of the jaw and atypical fractures. This post hoc analysis used surrogate markers to demonstrate that prolonged ZA administration does not cause bone saturation. Furthermore, reduction in ZA dosing frequency does not affect its retention level in bones over time. These findings will help in addressing clinicians' concerns regarding prolonged ZA administration. PMID- 30297387 TI - Five minutes with . . . Terry Kemple on the Green Impact for Health toolkit. PMID- 30297385 TI - Phase I/II Trial of Vandetanib and Bortezomib in Adults with Locally Advanced or Metastatic Medullary Thyroid Cancer. AB - LESSONS LEARNED: Vandetanib at a dose of 300 mg orally every day plus bortezomib 1.3 mg/m2 intravenously on days 1, 4, 8, and 11 could be administered safely.Assessing outcomes in 17 patients with medullary thyroid cancer, investigators considered the combination to be more difficult to administer than single-agent vandetanib and that achieving better outcomes was unlikely. Consequently, a planned phase II study was terminated early. BACKGROUND: The proto-oncogene RET (REarranged during Transfection) has a critical role in the pathogenesis of medullary thyroid cancer (MTC). Vandetanib (V), a multitargeted tyrosine kinase inhibitor approved for the treatment of MTC, is thought to inhibit RET in MTC. Supported by preclinical studies demonstrating that bortezomib (B) administration lowered RET mRNA and protein levels, we conducted a phase I study in advanced solid tumors of vandetanib in combination with bortezomib. The goal was to establish an RP2D (recommended phase II dose) for the combination of vandetanib plus bortezomib, a regimen envisioned as a dual strategy for targeting RET in MTC. METHODS: Patients with advanced solid tumors were treated with escalating doses of bortezomib or vandetanib to assess the safety and tolerability of daily oral vandetanib and intravenous (IV) bortezomib administered on days 1, 4, 8, and 11 of a 28-day cycle. Intrapatient dose escalation was allowed. RESULTS: Twenty-two patients were enrolled and received escalating mg/m2 bortezomib and mg vandetanib (number of patients) at initial doses of 1 and 100 (3), 1.3 and 100 (6), 1.3 and 200 (6), and 1.3 and 300 (7), respectively. Patients received a median of four cycles of bortezomib/vandetanib (range: 1-10), with 13 patients escalating to 1.3/200 and 10 to 1.3/300. G3 toxicities occurring in more than one patient included hypertension (24%), fatigue (19%), thrombocytopenia (10%), diarrhea (10%), and arthralgia (10%). There were no drug-related G4/5 toxicities. There was one dose-limiting toxicity, G3 thrombocytopenia, at bortezomib/vandetanib doses of 1.3/200 in cycle 2 that resolved without intervention. Four patients with a diagnosis of MTC (27%) had a partial response (PR). CONCLUSION: The MTD of the combination was established as bortezomib, 1.3 mg/m2 IV days 1, 4, 8, and 11 with vandetanib 300 mg p.o. daily. RECIST responses were observed in patients with a diagnosis of MTC. PMID- 30297388 TI - Excess deaths: government review should include the use of occupied bed space. PMID- 30297390 TI - Prostate cancer aggressiveness and age: Impact of p53, BCL-2 and microvessel density. AB - Older men are more likely to have advanced prostate cancer at time of their diagnosis, but whether prostate tumors are inherently (biologically) more aggressive with advancing age is uncertain. To address this gap in knowledge, we analyzed data from veterans (n=971) diagnosed with prostate cancer during 1991 1995. Factors included age, detection of prostate cancer by screening, prostate specific antigen (PSA) level, anatomic stage, and Gleason score. Information on molecular markers obtained from immunohistochemical staining of prostate tissue, included B cell lymphoma-2 (bcl-2), p53, and microvessel density (MVD), each having a previously documented association with disease progression and increased risk of prostate cancer death. We first examined the bivariate association of demographic, clinical, and molecular factors with age, and found evidence that race, screening status, Gleason score, PSA, bcl-2, p53, and MVD varied across categories of age in this study population. After further characterizing the association between age and Gleason score, we used logistic regression to examine the association between age and molecular markers-accounting for race, screening status, PSA, and Gleason score. Comparing men older than 80 years to those younger than 70 years, adjusted ORs and 95% CIs were 1.89 (0.73 to 4.92), 1.91 (1.05 to 3.46), and 2.00 (1.06 to 3.78), for positive bcl-2, p53, and MVD markers, respectively; no statistically significant associations were found for men 70-79 years old, compared with men younger than 70 years. These novel findings suggest that very elderly men often present with biologically aggressive prostate cancer; the results also have potential implications for therapeutic decision-making. PMID- 30297391 TI - The low but uncertain measured benefits of US water quality policy. AB - US investment to decrease pollution in rivers, lakes, and other surface waters has exceeded $1.9 trillion since 1960, and has also exceeded the cost of most other US environmental initiatives. These investments come both from the 1972 Clean Water Act and the largely voluntary efforts to control pollution from agriculture and urban runoff. This paper reviews the methods and conclusions of about 20 recent evaluations of these policies. Surprisingly, most analyses estimate that these policies' benefits are much smaller than their costs; the benefit-cost ratio from the median study is 0.37. However, existing evidence is limited and undercounts many types of benefits. We conclude that it is unclear whether many of these regulations truly fail a benefit-cost test or whether existing evidence understates their net benefits; we also describe specific questions that when answered would help eliminate this uncertainty. PMID- 30297389 TI - Kinesin-binding-triggered conformation switching of microtubules contributes to polarized transport. AB - Kinesin-1, the founding member of the kinesin superfamily of proteins, is known to use only a subset of microtubules for transport in living cells. This biased use of microtubules is proposed as the guidance cue for polarized transport in neurons, but the underlying mechanisms are still poorly understood. Here, we report that kinesin-1 binding changes the microtubule lattice and promotes further kinesin-1 binding. This high-affinity state requires the binding of kinesin-1 in the nucleotide-free state. Microtubules return to the initial low affinity state by washing out the binding kinesin-1 or by the binding of non hydrolyzable ATP analogue AMPPNP to kinesin-1. X-ray fiber diffraction, fluorescence speckle microscopy, and second-harmonic generation microscopy, as well as cryo-EM, collectively demonstrated that the binding of nucleotide-free kinesin-1 to GDP microtubules changes the conformation of the GDP microtubule to a conformation resembling the GTP microtubule. PMID- 30297394 TI - Localized prosocial preferences, public goods, and common-pool resources. AB - The presence of prosocial preferences is thought to reduce significantly the difficulty of solving societal collective action problems such as providing public goods (or reducing public bads). However, prosociality is often limited to members of an in-group. We present a general theoretical model where society is split into subgroups and people care more about the welfare of others in their own subgroup than they do about those in out-groups. Individual contributions to the public good spill over and benefit members in each group to different degrees. We then consider special cases of our general model under which we can examine the consequences of localized prosociality for the economic outcomes of society as a whole. We ask to what extent prosociality closes the welfare gap between the Nash equilibrium without prosociality and the social optimum. The answer depends on whether private and public inputs are good or poor substitutes in producing final output. Critically, the degree to which this welfare gap closes is a concave function of the level of prosociality in the case of poor substitutes, so even low levels of prosociality can lead to social welfare near the social optimum. PMID- 30297392 TI - p38alpha MAPK signaling drives pharmacologically reversible brain and gastrointestinal phenotypes in the SERT Ala56 mouse. AB - Autism spectrum disorder (ASD) is a common neurobehavioral disorder with limited treatment options. Activation of p38 MAPK signaling networks has been identified in ASD, and p38 MAPK signaling elevates serotonin (5-HT) transporter (SERT) activity, effects mimicked by multiple, hyperfunctional SERT coding variants identified in ASD subjects. Mice expressing the most common of these variants (SERT Ala56) exhibit hyperserotonemia, a biomarker observed in ASD subjects, as well as p38 MAPK-dependent SERT hyperphosphorylation, elevated hippocampal 5-HT clearance, hypersensitivity of CNS 5-HT1A and 5-HT2A/2C receptors, and behavioral and gastrointestinal perturbations reminiscent of ASD. As the alpha-isoform of p38 MAPK drives SERT activation, we tested the hypothesis that CNS-penetrant, alpha-isoform-specific p38 MAPK inhibitors might normalize SERT Ala56 phenotypes. Strikingly, 1-week treatment of adult SERT Ala56 mice with MW150, a selective p38alpha MAPK inhibitor, normalized hippocampal 5-HT clearance, CNS 5-HT1A and 5 HT2A/2C receptor sensitivities, social interactions, and colonic motility. Conditional elimination of p38alpha MAPK in 5-HT neurons of SERT Ala56 mice restored 5-HT1A and 5-HT2A/2C receptor sensitivities as well as social interactions, mirroring effects of MW150. Our findings support ongoing p38alpha MAPK activity as an important determinant of the physiological and behavioral perturbations of SERT Ala56 mice and, more broadly, supports consideration of p38alpha MAPK inhibition as a potential treatment for core and comorbid phenotypes present in ASD subjects. PMID- 30297393 TI - Histone methylation regulator PTIP is required to maintain normal and leukemic bone marrow niches. AB - The bone is essential for locomotion, calcium storage, and harboring the hematopoietic stem cells (HSCs) that supply the body with mature blood cells throughout life. HSCs reside at the interface of the bone and bone marrow (BM), where active bone remodeling takes place. Although the cellular components of the BM niche have been characterized, little is known about its epigenetic regulation. Here we find that the histone methylation regulator PTIP (Pax interaction with transcription-activation domain protein-1) is required to maintain the integrity of the BM niche by promoting osteoclast differentiation. PTIP directly promotes chromatin changes required for the expression of Ppargamma (peroxisome proliferator-activated receptor-gamma), a transcription factor essential for osteoclastogenesis. PTIP deletion leads to a drastic reduction of HSCs in the BM and induces extramedullary hematopoiesis. Furthermore, exposure of acute myeloid leukemia cells to a PTIP-deficient BM microenvironment leads to a reduction in leukemia-initiating cells and increased survival upon transplantation. Taken together, our data identify PTIP as an epigenetic regulator of osteoclastogenesis that is required for the integrity of the BM niche to sustain both normal hematopoiesis and leukemia. PMID- 30297395 TI - Protective immunity in recurrent Staphylococcus aureus infection reflects localized immune signatures and macrophage-conferred memory. AB - Staphylococcus aureus is the leading cause of skin and skin structure infection (SSSI), a primary portal of entry for invasive infection. Our prior studies discovered a role for protective innate memory against recurrent methicillin resistant S. aureus (MRSA) SSSI. In the present study, the dynamics and mechanisms of this response were explored in recurrent SSSI in WT mice. Priming by prior infection reduced skin lesion severity and MRSA burden, and protected against dissemination at day 7 but not day 2. Cytokine and cellular signatures in SSSI differed at day 2 versus 7, and were distinct in skin versus blood or spleen. Cytokines associated with protection in skin included increased IL-17, IL 6, monokine inducible by IFN-gamma (MIG), and RANTES, while increased IP-10 correlated with protection from dissemination. Cellular signatures of protection included increased Th17, M1 macrophage, and dendritic cell populations in abscesses, and total macrophages in lymph nodes. Priming potentiated S. aureus specific phagocytic killing by bone marrow-derived macrophages in vitro, and their adoptive transfer into naive skin afforded protective efficacy in vivo. Present findings indicate that protective immunity in recurrent S. aureus infection is locally targeted, and involves specific memory conferred by macrophages. These insights provide targets for vaccine and immunotherapeutic development against MRSA. PMID- 30297396 TI - iNOS promotes CD24+CD133+ liver cancer stem cell phenotype through a TACE/ADAM17 dependent Notch signaling pathway. AB - The inducible nitric oxide synthase (iNOS) is associated with more aggressive solid tumors, including hepatocellular carcinoma (HCC). Notch signaling in cancer stem cells promotes cancer progression and requires Notch cleavage by ADAM (a disintegrin and metalloprotease) proteases. We hypothesized that iNOS/NO promotes Notch1 activation through TACE/ADAM17 activation in liver cancer stem cells (LCSCs), leading to a more aggressive cancer phenotype. Expression of the stem cell markers CD24 and CD133 in the tumors of patients with HCC was associated with greater iNOS expression and worse outcomes. The expression of iNOS in CD24+CD133+ LCSCs, but not CD24-CD133- LCSCs, promoted Notch1 signaling and stemness characteristics in vitro and in vivo, as well as accelerating HCC initiation and tumor formation in the mouse xenograft tumor model. iNOS/NO led to Notch1 signaling through a pathway involving the soluble guanylyl cyclase/cGMP/PKG-dependent activation of TACE/ADAM17 and up-regulation of iRhom2 in LCSCs. In patients with HCC, higher TACE/ADAM17 expression and Notch1 activation correlated with poor prognosis. These findings link iNOS to Notch1 signaling in CD24+CD133+ LCSCs through the activation of TACE/ADAM17 and identify a mechanism for how iNOS contributes to progression of CD24+CD133+ HCC. PMID- 30297398 TI - Volatile loss following cooling and accretion of the Moon revealed by chromium isotopes. AB - Terrestrial and lunar rocks share chemical and isotopic similarities in refractory elements, suggestive of a common precursor. By contrast, the marked depletion of volatile elements in lunar rocks together with their enrichment in heavy isotopes compared with Earth's mantle suggests that the Moon underwent evaporative loss of volatiles. However, whether equilibrium prevailed during evaporation and, if so, at what conditions (temperature, pressure, and oxygen fugacity) remain unconstrained. Chromium may shed light on this question, as it has several thermodynamically stable, oxidized gas species that can distinguish between kinetic and equilibrium regimes. Here, we present high-precision Cr isotope measurements in terrestrial and lunar rocks that reveal an enrichment in the lighter isotopes of Cr in the Moon compared with Earth's mantle by 100 +/- 40 ppm per atomic mass unit. This observation is consistent with Cr partitioning into an oxygen-rich vapor phase in equilibrium with the proto-Moon, thereby stabilizing the CrO2 species that is isotopically heavy compared with CrO in a lunar melt. Temperatures of 1,600-1,800 K and oxygen fugacities near the fayalite magnetite-quartz buffer are required to explain the elemental and isotopic difference of Cr between Earth's mantle and the Moon. These temperatures are far lower than modeled in the aftermath of a giant impact, implying that volatile loss did not occur contemporaneously with impact but following cooling and accretion of the Moon. PMID- 30297397 TI - Differential regulation of PD-L1 expression by immune and tumor cells in NSCLC and the response to treatment with atezolizumab (anti-PD-L1). AB - Programmed death-ligand 1 (PD-L1) expression on tumor cells (TCs) by immunohistochemistry is rapidly gaining importance as a diagnostic for the selection or stratification of patients with non-small cell lung cancer (NSCLC) most likely to respond to single-agent checkpoint inhibitors. However, at least two distinct patterns of PD-L1 expression have been observed with potential biological and clinical relevance in NSCLC: expression on TC or on tumor infiltrating immune cells (ICs). We investigated the molecular and cellular characteristics associated with PD-L1 expression in these distinct cell compartments in 4,549 cases of NSCLC. PD-L1 expression on IC was more prevalent and likely reflected IFN-gamma-induced adaptive regulation accompanied by increased tumor-infiltrating lymphocytes and effector T cells. High PD-L1 expression on TC, however, reflected an epigenetic dysregulation of the PD-L1 gene and was associated with a distinct histology described by poor immune infiltration, sclerotic/desmoplastic stroma, and mesenchymal molecular features. Importantly, durable clinical responses to atezolizumab (anti-PD-L1) were observed in patients with tumors expressing high PD-L1 levels on either TC alone [40% objective response rate (ORR)] or IC alone (22% ORR). Thus, PD-L1 expression on TC or IC can independently attenuate anticancer immunity and emphasizes the functional importance of IC in regulating the antitumor T cell response.

PMID- 30297400 TI - Neural reactivation in parietal cortex enhances memory for episodically linked information. AB - Remembering is a complex process that involves recalling specific details, such as who you were with when you celebrated your last birthday, as well as contextual information, such as the place where you celebrated. It is well established that the act of remembering enhances long-term retention of the retrieved information, but the neural and cognitive mechanisms that drive memory enhancement are not yet understood. One possibility is that the process of remembering results in reactivation of the broader episodic context. Consistent with this idea, in two experiments, we found that multiple retrieval attempts enhanced long-term retention of both the retrieved object and the nontarget object that shared scene context, compared with a restudy control. Using representational similarity analysis of fMRI data in experiment 2, we found that retrieval resulted in greater neural reactivation of both the target objects and contextually linked objects compared with restudy. Furthermore, this reactivation occurred in a network of medial and lateral parietal lobe regions that have been linked to episodic recollection. The results demonstrate that retrieving a memory can enhance retention of information that is linked in the broader event context and the hippocampus and a posterior medial network of parietal cortical areas (also known as the Default Network) play complementary roles in supporting the reactivation of episodically linked information during retrieval.

AB - Bottom trawlers land around 19 million tons of fish and invertebrates annually, almost one-quarter of wild marine landings. The extent of bottom trawling footprint (seabed area trawled at least once in a specified region and time period) is often contested but poorly described. We quantify footprints using high-resolution satellite vessel monitoring system (VMS) and logbook data on 24 continental shelves and slopes to 1,000-m depth over at least 2 years. Trawling footprint varied markedly among regions: from <10% of seabed area in Australian and New Zealand waters, the Aleutian Islands, East Bering Sea, South Chile, and Gulf of Alaska to >50% in some European seas. Overall, 14% of the 7.8 million-km2 study area was trawled, and 86% was not trawled. Trawling activity was aggregated; the most intensively trawled areas accounting for 90% of activity comprised 77% of footprint on average. Regional swept area ratio (SAR; ratio of total swept area trawled annually to total area of region, a metric of trawling intensity) and footprint area were related, providing an approach to estimate regional trawling footprints when high-resolution spatial data are unavailable. If SAR was <=0.1, as in 8 of 24 regions, there was >95% probability that >90% of seabed was not trawled. If SAR was 7.9, equal to the highest SAR recorded, there was >95% probability that >70% of seabed was trawled. Footprints were smaller and SAR was <=0.25 in regions where fishing rates consistently met international sustainability benchmarks for fish stocks, implying collateral environmental benefits from sustainable fishing. PMID- 30297402 TI - Functional and evolutionary characterization of a secondary metabolite gene cluster in budding yeasts. AB - Secondary metabolites are key in how organisms from all domains of life interact with their environment and each other. The iron-binding molecule pulcherrimin was described a century ago, but the genes responsible for its production in budding yeasts have remained uncharacterized. Here, we used phylogenomic footprinting on 90 genomes across the budding yeast subphylum Saccharomycotina to identify the gene cluster associated with pulcherrimin production. Using targeted gene replacements in Kluyveromyces lactis, we characterized the four genes that make up the cluster, which likely encode two pulcherriminic acid biosynthesis enzymes, a pulcherrimin transporter, and a transcription factor involved in both biosynthesis and transport. The requirement of a functional putative transporter to utilize extracellular pulcherrimin-complexed iron demonstrates that pulcherriminic acid is a siderophore, a chelator that binds iron outside the cell for subsequent uptake. Surprisingly, we identified homologs of the putative transporter and transcription factor genes in multiple yeast genera that lacked the biosynthesis genes and could not make pulcherrimin, including the model yeast Saccharomyces cerevisiae We deleted these previously uncharacterized genes and showed they are also required for pulcherrimin utilization in S. cerevisiae, raising the possibility that other genes of unknown function are linked to secondary metabolism. Phylogenetic analyses of this gene cluster suggest that pulcherrimin biosynthesis and utilization were ancestral to budding yeasts, but the biosynthesis genes and, subsequently, the utilization genes, were lost in many lineages, mirroring other microbial public goods systems that lead to the rise of cheater organisms. PMID- 30297403 TI - Changes in temperature alter the relationship between biodiversity and ecosystem functioning. AB - Global warming and the loss of biodiversity through human activities (e.g., land use change, pollution, invasive species) are two of the most profound threats to the functional integrity of the Earth's ecosystems. These factors are, however, most frequently investigated separately, ignoring the potential for synergistic effects of biodiversity loss and environmental warming on ecosystem functioning. Here we use high-throughput experiments with microbial communities to investigate how changes in temperature affect the relationship between biodiversity and ecosystem functioning. We found that changes in temperature systematically altered the relationship between biodiversity and ecosystem functioning. As temperatures departed from ambient conditions the exponent of the diversity functioning relationship increased, meaning that more species were required to maintain ecosystem functioning under thermal stress. This key result was driven by two processes linked to variability in the thermal tolerance curves of taxa. First, more diverse communities had a greater chance of including species with thermal traits that enabled them to maintain productivity as temperatures shifted from ambient conditions. Second, we found a pronounced increase in the contribution of complementarity to the net biodiversity effect at high and low temperatures, indicating that changes in species interactions played a critical role in mediating the impacts of temperature change on the relationship between biodiversity and ecosystem functioning. Our results highlight that if biodiversity loss occurs independently of species' thermal tolerance traits, then the additional impacts of environmental warming will result in sharp declines in ecosystem function.

PMID- 30297404 TI - Mitosis-specific MRN complex promotes a mitotic signaling cascade to regulate spindle dynamics and chromosome segregation. AB - The MRE11-RAD50-NBS1 (MRN) complex is well known for participating in DNA damage response pathways in all phases of cell cycle. Here, we show that MRN constitutes a mitosis-specific complex, named mMRN, with a protein, MMAP. MMAP directly interacts with MRE11 and is required for optimal stability of the MRN complex during mitosis. MMAP colocalizes with MRN in mitotic spindles, and MMAP-deficient cells display abnormal spindle dynamics and chromosome segregation similar to MRN deficient cells. Mechanistically, both MMAP and MRE11 are hyperphosphorylated by the mitotic kinase, PLK1; and the phosphorylation is required for assembly of the mMRN complex. The assembled mMRN complex enables PLK1 to interact with and activate the microtubule depolymerase, KIF2A, leading to spindle turnover and chromosome segregation. Our study identifies a mitosis-specific version of the MRN complex that acts in the PLK1-KIF2A signaling cascade to regulate spindle dynamics and chromosome distribution. PMID- 30297406 TI - Selection and gene flow shape genomic islands that control floral guides. AB - Genomes of closely-related species or populations often display localized regions of enhanced relative sequence divergence, termed genomic islands. It has been proposed that these islands arise through selective sweeps and/or barriers to gene flow. Here, we genetically dissect a genomic island that controls flower color pattern differences between two subspecies of Antirrhinum majus, A.m.striatum and A.m.pseudomajus, and relate it to clinal variation across a natural hybrid zone. We show that selective sweeps likely raised relative divergence at two tightly-linked MYB-like transcription factors, leading to distinct flower patterns in the two subspecies. The two patterns provide alternate floral guides and create a strong barrier to gene flow where populations come into contact. This barrier affects the selected flower color genes and tightly-linked loci, but does not extend outside of this domain, allowing gene flow to lower relative divergence for the rest of the chromosome. Thus, both selective sweeps and barriers to gene flow play a role in shaping genomic islands: sweeps cause elevation in relative divergence, while heterogeneous gene flow flattens the surrounding "sea," making the island of divergence stand out. By showing how selective sweeps establish alternative adaptive phenotypes that lead to barriers to gene flow, our study sheds light on possible mechanisms leading to reproductive isolation and speciation. PMID- 30297407 TI - Magnetic map in nonanadromous Atlantic salmon. AB - Long-distance migrants, including Pacific salmon (Oncorhynchus spp), can use geomagnetic information to navigate. We tested the hypothesis that a "magnetic map" (i.e., an ability to extract positional information from Earth's magnetic field) also exists in a population of salmon that do not undertake oceanic migrations. This study examined juvenile Atlantic salmon (Salmo salar) originally from a nonanadromous population in Maine transferred ~60 years ago to a lake in central Oregon. We exposed juveniles to magnetic displacements representative of locations at the latitudinal boundaries of the Pacific salmon oceanic range in the North Pacific and at the periphery of their ancestral oceanic range in the North Atlantic. Orientation differed among the magnetic treatments, indicating that Atlantic salmon detect map information from the geomagnetic field. Despite no recent history of ocean migration, these fish displayed adaptive orientation responses similar to those observed in native Pacific salmonids. These findings indicate that use of map information from the geomagnetic field is a shared ancestral character in the family Salmonidae and is not restricted to populations with anadromous life histories. Lastly, given that Atlantic salmon are transported throughout the world for capture fisheries and aquaculture, such a robust navigational system is of some concern. Escaped individuals may have greater potential to successfully navigate, and thus invade, introduced habitats than previously suspected. PMID- 30297408 TI - Interplay between coronavirus, a cytoplasmic RNA virus, and nonsense-mediated mRNA decay pathway. AB - Coronaviruses (CoVs), including severe acute respiratory syndrome CoV and Middle East respiratory syndrome CoV, are enveloped RNA viruses that carry a large positive-sense single-stranded RNA genome and cause a variety of diseases in humans and domestic animals. Very little is known about the host pathways that regulate the stability of CoV mRNAs, which carry some unusual features. Nonsense mediated decay (NMD) is a eukaryotic RNA surveillance pathway that detects mRNAs harboring aberrant features and targets them for degradation. Although CoV mRNAs are of cytoplasmic origin, the presence of several NMD-inducing features (including multiple ORFs with internal termination codons that create a long 3' untranslated region) in CoV mRNAs led us to explore the interplay between the NMD pathway and CoVs. Our study using murine hepatitis virus as a model CoV showed that CoV mRNAs are recognized by the NMD pathway as a substrate, resulting in their degradation. Furthermore, CoV replication induced the inhibition of the NMD pathway, and N protein (a viral structural protein) had an NMD inhibitory function that protected viral mRNAs from rapid decay. Our data further suggest that the NMD pathway interferes with optimal viral replication by degrading viral mRNAs early in infection, before sufficient accumulation of N protein. Our study presents clear evidence for the biological importance of the NMD pathway in controlling the stability of mRNAs and the efficiency of replication of a cytoplasmic RNA virus.

PMID- 30297409 TI - Yin-and-yang bifurcation of opioidergic circuits for descending analgesia at the midbrain of the mouse. AB - In the descending analgesia pathway, opioids are known to disinhibit the projections from the periaqueductal gray (PAG) to the rostral ventromedial medulla (RVM), leading to suppression of pain signals at the spinal cord level. The locus coeruleus (LC) has been proposed to engage in the descending pathway through noradrenergic inputs to the spinal cord. Nevertheless, how the LC is integrated in the descending analgesia circuit has remained unknown. Here, we show that the opioidergic analgesia pathway is bifurcated in structure and function at the PAG. A knockout as well as a PAG-specific knockdown of phospholipase C beta4 (PLCbeta4), a signaling molecule for G protein-coupled receptors, enhanced swim stress-induced and morphine-induced analgesia in mice. Immunostaining after simultaneous retrograde labeling from the RVM and the LC revealed two mutually exclusive neuronal populations at the PAG, each projecting either to the LC or the RVM, with PLCbeta4 expression only in the PAG-LC projecting cells that provide a direct synaptic input to LC-spinal cord (SC) projection neurons. The PAG-LC projection neurons in wild-type mice turned quiescent in response to opiates, but remained active in the PLCbeta4 mutant, suggesting a possibility that an increased adrenergic function induced by the persistent PAG-LC activity underlies the enhanced opioid analgesia in the mutant. Indeed, the enhanced analgesia in the mutant was reversed by blocking alpha2 noradrenergic receptors. These findings indicate that opioids suppress descending analgesia through the PAG-LC pathway, while enhancing it through the PAG-RVM pathway, i.e., two distinct pathways with opposing effects on opioid analgesia. These results point to a therapeutic target in pain control. PMID- 30297412 TI - Progressive aridification in East Africa over the last half million years and implications for human evolution. AB - Evidence for Quaternary climate change in East Africa has been derived from outcrops on land and lake cores and from marine dust, leaf wax, and pollen records. These data have previously been used to evaluate the impact of climate change on hominin evolution, but correlations have proved to be difficult, given poor data continuity and the great distances between marine cores and terrestrial basins where fossil evidence is located. Here, we present continental coring evidence for progressive aridification since about 575 thousand years before present (ka), based on Lake Magadi (Kenya) sediments. This long-term drying trend was interrupted by many wet-dry cycles, with the greatest variability developing during times of high eccentricity-modulated precession. Intense aridification apparent in the Magadi record took place between 525 and 400 ka, with relatively persistent arid conditions after 350 ka and through to the present. Arid conditions in the Magadi Basin coincide with the Mid-Brunhes Event and overlap with mammalian extinctions in the South Kenya Rift between 500 and 400 ka. The 525 to 400 ka arid phase developed in the South Kenya Rift between the period when the last Acheulean tools are reported (at about 500 ka) and before the appearance of Middle Stone Age artifacts (by about 320 ka). Our data suggest that increasing Middle- to Late-Pleistocene aridification and environmental variability may have been drivers in the physical and cultural evolution of Homo sapiens in East Africa. PMID- 30297411 TI - Dopaminergic basis for signaling belief updates, but not surprise, and the link to paranoia. AB - Distinguishing between meaningful and meaningless sensory information is fundamental to forming accurate representations of the world. Dopamine is thought to play a central role in processing the meaningful information content of observations, which motivates an agent to update their beliefs about the environment. However, direct evidence for dopamine's role in human belief updating is lacking. We addressed this question in healthy volunteers who performed a model-based fMRI task designed to separate the neural processing of meaningful and meaningless sensory information. We modeled participant behavior using a normative Bayesian observer model and used the magnitude of the model derived belief update following an observation to quantify its meaningful information content. We also acquired PET imaging measures of dopamine function in the same subjects. We show that the magnitude of belief updates about task structure (meaningful information), but not pure sensory surprise (meaningless information), are encoded in midbrain and ventral striatum activity. Using PET we show that the neural encoding of meaningful information is negatively related to dopamine-2/3 receptor availability in the midbrain and dexamphetamine-induced dopamine release capacity in the striatum. Trial-by-trial analysis of task performance indicated that subclinical paranoid ideation is negatively related to behavioral sensitivity to observations carrying meaningful information about the task structure. The findings provide direct evidence implicating dopamine in model-based belief updating in humans and have implications for understating the pathophysiology of psychotic disorders where dopamine function is disrupted. PMID- 30297413 TI - Entropic contribution to enhanced thermal stability in the thermostable P450 CYP119. AB - The enhanced thermostability of thermophilic proteins with respect to their mesophilic counterparts is often attributed to the enthalpy effect, arising from strong interactions between protein residues. Intuitively, these strong interresidue interactions will rigidify the biomolecules. However, the present work utilizing neutron scattering and solution NMR spectroscopy measurements demonstrates a contrary example that the thermophilic cytochrome P450, CYP119, is much more flexible than its mesophilic counterpart, CYP101A1, something which is not apparent just from structural comparison of the two proteins. A mechanism to explain this apparent contradiction is that higher flexibility in the folded state of CYP119 increases its conformational entropy and thereby reduces the entropy gain during denaturation, which will increase the free energy needed for unfolding and thus stabilize the protein. This scenario is supported by thermodynamic data on the temperature dependence of unfolding free energy, which shows a significant entropic contribution to the thermostability of CYP119 and lends an added dimension to enhanced stability, previously attributed only to presence of aromatic stacking interactions and salt bridge networks. Our experimental data also support the notion that highly thermophilic P450s such as CYP119 may use a mechanism that partitions flexibility differently from mesophilic P450s between ligand binding and thermal stability. PMID- 30297414 TI - MRI-based assessment of function and dysfunction in myelinated axons. AB - Repetitive electrical activity produces microstructural alteration in myelinated axons, which may afford the opportunity to noninvasively monitor function of myelinated fibers in peripheral nervous system (PNS)/CNS pathways. Microstructural changes were assessed via two different magnetic-resonance-based approaches: diffusion fMRI and dynamic T2 spectroscopy in the ex vivo perfused bullfrog sciatic nerves. Using this robust, classical model as a platform for testing, we demonstrate that noninvasive diffusion fMRI, based on standard diffusion tensor imaging (DTI), can clearly localize the sites of axonal conduction blockage as might be encountered in neurotrauma or other lesion types. It is also shown that the diffusion fMRI response is graded in proportion to the total number of electrical impulses carried through a given locus. Dynamic T2 spectroscopy of the perfused frog nerves point to an electrical-activity-induced redistribution of tissue water and myelin structural changes. Diffusion basis spectrum imaging (DBSI) reveals a reversible shift of tissue water into a restricted isotropic diffusion signal component. Submyelinic vacuoles are observed in electron-microscopy images of tissue fixed during electrical stimulation. A slowing of the compound action potential conduction velocity accompanies repetitive electrical activity. Correlations between electrophysiology and MRI parameters during and immediately after stimulation are presented. Potential mechanisms and interpretations of these results are discussed. PMID- 30297416 TI - Salt and marine products in the Classic Maya economy from use-wear study of stone tools. AB - Microscopic study of the edges of Late to Terminal Classic Maya (AD 600-900) chert stone tools from the Paynes Creek Salt Works, Belize, indicates most tools were used for cutting fish or meat or working hide, which was unexpected, given the virtual absence of fish or other animal remains at this large salt-production complex. Use-wear study shows that a minority of stone tools have edge-wear from woodworking. Our study suggests that salting fish was a significant activity at the salt works, which corresponds to Roman, Chinese, and other East Asian civilizations, where salt and salted fish were critical components of food storage, trade, and state finance. Based on analogy with modern Maya salt producers at Sacapulas, Guatemala, we provide estimates of the amounts of salt and salted fish produced at the Paynes Creek Salt Works and the implications for the Classic Maya economy. Salt cakes and salted fish were preserved commodities that could be stored and traded in the marketplace. PMID- 30297415 TI - Long noncoding RNA GM12371 acts as a transcriptional regulator of synapse function. AB - Despite the growing evidence suggesting that long noncoding RNAs (lncRNAs) are critical regulators of several biological processes, their functions in the nervous system remain elusive. We have identified an lncRNA, GM12371, in hippocampal neurons that is enriched in the nucleus and necessary for synaptic communication, synapse density, synapse morphology, and dendritic tree complexity. Mechanistically, GM12371 regulates the expression of several genes involved in neuronal development and differentiation, as well as expression of specific lncRNAs and their cognate mRNA targets. Furthermore, we find that cAMP PKA signaling up-regulates the expression of GM12371 and that its expression is essential for the activity-dependent changes in synaptic transmission in hippocampal neurons. Taken together, our data establish a key role for GM12371 in regulating synapse function. PMID- 30297417 TI - Elongation factor P is required to maintain proteome homeostasis at high growth rate. AB - Elongation factor P (EF-P) is a universally conserved translation factor that alleviates ribosome pausing at polyproline (PPX) motifs by facilitating peptide bond formation. In the absence of EF-P, PPX peptide bond formation can limit translation rate, leading to pleotropic phenotypes including slowed growth, increased antibiotic sensitivity, and loss of virulence. In this study, we observe that many of these phenotypes are dependent on growth rate. Limiting growth rate suppresses a variety of detrimental phenotypes associated with ribosome pausing at PPX motifs in the absence of EF-P. Polysome levels are also similar to wild-type under slow growth conditions, consistent with global changes in ribosome queuing in cells without EF-P when growth rate is decreased. Inversely, under high protein synthesis demands, we observe that Escherichia coli lacking EF-P have reduced fitness. Our data demonstrate that EF-P-mediated relief of ribosome queuing is required to maintain proteome homeostasis under conditions of high translational demands. PMID- 30297418 TI - DSCAM promotes self-avoidance in the developing mouse retina by masking the functions of cadherin superfamily members. AB - During neural development, self-avoidance ensures that a neuron's processes arborize to evenly fill a particular spatial domain. At the individual cell level, self-avoidance is promoted by genes encoding cell-surface molecules capable of generating thousands of diverse isoforms, such as Dscam1 (Down syndrome cell adhesion molecule 1) in Drosophila Isoform choice differs between neighboring cells, allowing neurons to distinguish "self" from "nonself". In the mouse retina, Dscam promotes self-avoidance at the level of cell types, but without extreme isoform diversity. Therefore, we hypothesize that DSCAM is a general self-avoidance cue that "masks" other cell type-specific adhesion systems to prevent overly exuberant adhesion. Here, we provide in vivo and in vitro evidence that DSCAM masks the functions of members of the cadherin superfamily, supporting this hypothesis. Thus, unlike the isoform-rich molecules tasked with self-avoidance at the individual cell level, here the diversity resides on the adhesive side, positioning DSCAM as a generalized modulator of cell adhesion during neural development. PMID- 30297420 TI - Distinct facial expressions represent pain and pleasure across cultures. AB - Real-world studies show that the facial expressions produced during pain and orgasm-two different and intense affective experiences-are virtually indistinguishable. However, this finding is counterintuitive, because facial expressions are widely considered to be a powerful tool for social interaction. Consequently, debate continues as to whether the facial expressions of these extreme positive and negative affective states serve a communicative function. Here, we address this debate from a novel angle by modeling the mental representations of dynamic facial expressions of pain and orgasm in 40 observers in each of two cultures (Western, East Asian) using a data-driven method. Using a complementary approach of machine learning, an information-theoretic analysis, and a human perceptual discrimination task, we show that mental representations of pain and orgasm are physically and perceptually distinct in each culture. Cross-cultural comparisons also revealed that pain is represented by similar face movements across cultures, whereas orgasm showed distinct cultural accents. Together, our data show that mental representations of the facial expressions of pain and orgasm are distinct, which questions their nondiagnosticity and instead suggests they could be used for communicative purposes. Our results also highlight the potential role of cultural and perceptual factors in shaping the mental representation of these facial expressions. We discuss new research directions to further explore their relationship to the production of facial expressions. PMID- 30297421 TI - Faults and associated karst collapse suggest conduits for fluid flow that influence hydraulic fracturing-induced seismicity. AB - During December 2011, a swarm of moderate-magnitude earthquakes was induced by hydraulic fracturing (HF) near Cardston, Alberta. Despite seismological associations linking these two processes, the hydrological and tectonic mechanisms involved remain unclear. In this study, we interpret a 3D reflection seismic survey to delve into the geological factors related to these earthquakes. First, we document a basement-rooted fault on which the earthquake rupture occurred that extends above the targeted reservoir. Second, at the reservoir's stratigraphic level, anomalous subcircular features are recognized along the fault and are interpreted as resulting from fault-associated karst processes. These observations have implications for HF-induced seismicity, as they suggest hydraulic communication over a large (vertical) distance, reconciling the discrepancy between the culprit well trajectory and earthquake hypocenters. We speculate on how these newly identified geological factors could drive the sporadic appearance of induced seismicity and thus be utilized to avoid earthquake hazards. PMID- 30297422 TI - Randomly distributed embedding making short-term high-dimensional data predictable. AB - Future state prediction for nonlinear dynamical systems is a challenging task, particularly when only a few time series samples for high-dimensional variables are available from real-world systems. In this work, we propose a model-free framework, named randomly distributed embedding (RDE), to achieve accurate future state prediction based on short-term high-dimensional data. Specifically, from the observed data of high-dimensional variables, the RDE framework randomly generates a sufficient number of low-dimensional "nondelay embeddings" and maps each of them to a "delay embedding," which is constructed from the data of a to be predicted target variable. Any of these mappings can perform as a low dimensional weak predictor for future state prediction, and all of such mappings generate a distribution of predicted future states. This distribution actually patches all pieces of association information from various embeddings unbiasedly or biasedly into the whole dynamics of the target variable, which after operated by appropriate estimation strategies, creates a stronger predictor for achieving prediction in a more reliable and robust form. Through applying the RDE framework to data from both representative models and real-world systems, we reveal that a high-dimension feature is no longer an obstacle but a source of information crucial to accurate prediction for short-term data, even under noise deterioration. PMID- 30297423 TI - Mountain snowpack response to different levels of warming. AB - Temperature variability impacts the distribution and persistence of the mountain snowpack, which critically provides snowmelt-derived water resources to large populations worldwide. Warmer temperatures decrease the amount of montane snow water equivalent (SWE), forcing its center of mass to higher elevations. We use a unique multivariate probabilistic framework to quantify the response of the 1 April SWE volume and its centroid to a 1.0 to 2.0 degrees C increase in winter air temperature across the Sierra Nevada (United States). A 1.0 degrees C increase reduces the probability of exceeding the long-term (1985-2016) average rangewide SWE volume (15.7 km3) by 20.7%. It correspondingly is 60.6% more likely for the centroid to be higher than its long-term average (2,540 m). We further show that a 1.5 and 2.0 degrees C increase in the winter temperature reduces the probability of exceeding the long-term average SWE volume by 31.0% and 41.1%, respectively, whereas it becomes 79.3% and 89.8% more likely that the centroid will be higher than 2,540 m for those respective temperature changes. We also characterize regional variability across the Sierra Nevada and show that the northwestern and southeastern regions of the mountain range are 30.3% and 14.0% less likely to have 1 April SWE volumes exceed their long-term average for a 1.0 degrees C increase about their respective average winter temperatures. Overall, the SWE in the northern Sierra Nevada exhibits higher hydrologic vulnerability to warming than in the southern region. Given the expected increases in mountain temperatures, the observed rates of change in SWE are expected to intensify in the future. PMID- 30297419 TI - Swi5-Sfr1 stimulates Rad51 recombinase filament assembly by modulating Rad51 dissociation. AB - Eukaryotic Rad51 protein is essential for homologous-recombination repair of DNA double-strand breaks. Rad51 recombinases first assemble onto single-stranded DNA to form a nucleoprotein filament, required for function in homology pairing and strand exchange. This filament assembly is the first regulation step in homologous recombination. Rad51 nucleation is kinetically slow, and several accessory factors have been identified to regulate this step. Swi5-Sfr1 (S5S1) stimulates Rad51-mediated homologous recombination by stabilizing Rad51 nucleoprotein filaments, but the mechanism of stabilization is unclear. We used single-molecule tethered particle motion experiments to show that mouse S5S1 (mS5S1) efficiently stimulates mouse RAD51 (mRAD51) nucleus formation and inhibits mRAD51 dissociation from filaments. We also used single-molecule fluorescence resonance energy transfer experiments to show that mS5S1 promotes stable nucleus formation by specifically preventing mRAD51 dissociation. This leads to a reduction of nucleation size from three mRAD51 to two mRAD51 molecules in the presence of mS5S1. Compared with mRAD51, fission yeast Rad51 (SpRad51) exhibits fast nucleation but quickly dissociates from the filament. SpS5S1 specifically reduces SpRad51 disassembly to maintain a stable filament. These results clearly demonstrate the conserved function of S5S1 by primarily stabilizing Rad51 on DNA, allowing both the formation of the stable nucleus and the maintenance of filament length. PMID- 30297424 TI - Empirical evidence of mental health risks posed by climate change. AB - Sound mental health-a critical facet of human wellbeing-has the potential to be undermined by climate change. Few large-scale studies have empirically examined this hypothesis. Here, we show that short-term exposure to more extreme weather, multiyear warming, and tropical cyclone exposure each associate with worsened mental health. To do so, we couple meteorological and climatic data with reported mental health difficulties drawn from nearly 2 million randomly sampled US residents between 2002 and 2012. We find that shifting from monthly temperatures between 25 degrees C and 30 degrees C to >30 degrees C increases the probability of mental health difficulties by 0.5% points, that 1 degrees C of 5 year warming associates with a 2% point increase in the prevalence of mental health issues, and that exposure to Hurricane Katrina associates with a 4% point increase in this metric. Our analyses provide added quantitative support for the conclusion that environmental stressors produced by climate change pose threats to human mental health. PMID- 30297425 TI - Whole-genome comparison of endogenous retrovirus segregation across wild and domestic host species populations. AB - Although recent advances in sequencing and computational analyses have facilitated use of endogenous retroviruses (ERVs) for deciphering coevolution among retroviruses and their hosts, sampling effects from different host populations present major challenges. Here we utilize available whole-genome data from wild and domesticated European rabbit (Oryctolagus cuniculus sp.) populations, sequenced as DNA pools by paired-end Illumina technology, for identifying segregating reference as well as nonreference ERV loci, to reveal their variation along the host phylogeny and domestication history. To produce new viruses, retroviruses must insert a proviral DNA copy into the host nuclear DNA. Occasional proviral insertions into the host germline have been passed down through generations as inherited ERVs during millions of years. These ERVs represent retroviruses that were active at the time of infection and thus present a remarkable record of historical virus-host associations. To examine segregating ERVs in host populations, we apply a reference library search strategy for anchoring ERV-associated short-sequence read pairs from pooled whole-genome sequences to reference genome assembly positions. We show that most ERVs segregate along host phylogeny but also uncover radiation of some ERVs, identified as segregating loci among wild and domestic rabbits. The study targets pertinent issues regarding genome sampling when examining virus-host evolution from the genomic ERV record and offers improved scope regarding common strategies for single-nucleotide variant analyses in host population comparative genomics. PMID- 30297427 TI - Profile of Mary E. Hatten. PMID- 30297426 TI - mTORC1 signaling suppresses Wnt/beta-catenin signaling through DVL-dependent regulation of Wnt receptor FZD level. AB - Wnt/beta-catenin signaling plays pivotal roles in cell proliferation and tissue homeostasis by maintaining somatic stem cell functions. The mammalian target of rapamycin (mTOR) signaling functions as an integrative rheostat that orchestrates various cellular and metabolic activities that shape tissue homeostasis. Whether these two fundamental signaling pathways couple to exert physiological functions still remains mysterious. Using a genome-wide CRISPR-Cas9 screening, we discover that mTOR complex 1 (mTORC1) signaling suppresses canonical Wnt/beta-catenin signaling. Deficiency in tuberous sclerosis complex 1/2 (TSC1/2), core negative regulators of mTORC1 activity, represses Wnt/beta-catenin target gene expression, which can be rescued by RAD001. Mechanistically, mTORC1 signaling regulates the cell surface level of Wnt receptor Frizzled (FZD) in a Dishevelled (DVL) dependent manner by influencing the association of DVL and clathrin AP-2 adaptor. Sustained mTORC1 activation impairs Wnt/beta-catenin signaling and causes loss of stemness in intestinal organoids ex vivo and primitive intestinal progenitors in vivo. Wnt/beta-catenin-dependent liver metabolic zonation gene expression program is also down-regulated by mTORC1 activation. Our study provides a paradigm that mTORC1 signaling cell autonomously regulates Wnt/beta-catenin pathway to influence stem cell maintenance. PMID- 30297429 TI - Cryo-ET reveals the macromolecular reorganization of S. pombe mitotic chromosomes in vivo. AB - Chromosomes condense during mitosis in most eukaryotes. This transformation involves rearrangements at the nucleosome level and has consequences for transcription. Here, we use cryo-electron tomography (cryo-ET) to determine the 3D arrangement of nuclear macromolecular complexes, including nucleosomes, in frozen-hydrated Schizosaccharomyces pombe cells. Using 3D classification analysis, we did not find evidence that nucleosomes resembling the crystal structure are abundant. This observation and those from other groups support the notion that a subset of fission yeast nucleosomes may be partially unwrapped in vivo. In both interphase and mitotic cells, there is also no evidence of monolithic structures the size of Hi-C domains. The chromatin is mingled with two features: pockets, which are positions free of macromolecular complexes; and "megacomplexes," which are multimegadalton globular complexes like preribosomes. Mitotic chromatin is more crowded than interphase chromatin in subtle ways. Nearest-neighbor distance analyses show that mitotic chromatin is more compacted at the oligonucleosome than the dinucleosome level. Like interphase, mitotic chromosomes contain megacomplexes and pockets. This uneven chromosome condensation helps explain a longstanding enigma of mitosis: a subset of genes is up-regulated. PMID- 30297428 TI - Genetic variation in the SIM1 locus is associated with erectile dysfunction. AB - Erectile dysfunction affects millions of men worldwide. Twin studies support the role of genetic risk factors underlying erectile dysfunction, but no specific genetic variants have been identified. We conducted a large-scale genome-wide association study of erectile dysfunction in 36,649 men in the multiethnic Kaiser Permanente Northern California Genetic Epidemiology Research in Adult Health and Aging cohort. We also undertook replication analyses in 222,358 men from the UK Biobank. In the discovery cohort, we identified a single locus (rs17185536-T) on chromosome 6 near the single-minded family basic helix-loop-helix transcription factor 1 (SIM1) gene that was significantly associated with the risk of erectile dysfunction (odds ratio = 1.26, P = 3.4 * 10-25). The association replicated in the UK Biobank sample (odds ratio = 1.25, P = 6.8 * 10-14), and the effect is independent of known erectile dysfunction risk factors, including body mass index (BMI). The risk locus resides on the same topologically associating domain as SIM1 and interacts with the SIM1 promoter, and the rs17185536-T risk allele showed differential enhancer activity. SIM1 is part of the leptin-melanocortin system, which has an established role in body weight homeostasis and sexual function. Because the variants associated with erectile dysfunction are not associated with differences in BMI, our findings suggest a mechanism that is specific to sexual function.

AB - The chiral Majorana fermion is a massless self-conjugate fermion which can arise as the edge state of certain 2D topological matters. It has been theoretically predicted and experimentally observed in a hybrid device of a quantum anomalous Hall insulator and a conventional superconductor. Its closely related cousin, the Majorana zero mode in the bulk of the corresponding topological matter, is known to be applicable in topological quantum computations. Here we show that the propagation of chiral Majorana fermions leads to the same unitary transformation as that in the braiding of Majorana zero modes and propose a platform to perform quantum computation with chiral Majorana fermions. A Corbino ring junction of the hybrid device can use quantum coherent chiral Majorana fermions to implement the Hadamard gate and the phase gate, and the junction conductance yields a natural readout for the qubit state. PMID- 30297430 TI - Humans incorporate attention-dependent uncertainty into perceptual decisions and confidence. AB - Perceptual decisions are better when they take uncertainty into account. Uncertainty arises not only from the properties of sensory input but also from cognitive sources, such as different levels of attention. However, it is unknown whether humans appropriately adjust for such cognitive sources of uncertainty during perceptual decision-making. Here we show that, in a task in which uncertainty is relevant for performance, human categorization and confidence decisions take into account uncertainty related to attention. We manipulated uncertainty in an orientation categorization task from trial to trial using only an attentional cue. The categorization task was designed to disambiguate decision rules that did or did not depend on attention. Using formal model comparison to evaluate decision behavior, we found that category and confidence decision boundaries shifted as a function of attention in an approximately Bayesian fashion. This means that the observer's attentional state on each trial contributed probabilistically to the decision computation. This responsiveness of an observer's decisions to attention-dependent uncertainty should improve perceptual decisions in natural vision, in which attention is unevenly distributed across a scene. PMID- 30297432 TI - Toxicity of an Fc-engineered anti-CD40 antibody is abrogated by intratumoral injection and results in durable antitumor immunity. AB - Immune stimulation has emerged as a promising approach to the treatment of neoplastic diseases. Currently approved therapeutics, such as anti-CTLA4 and anti PD1, are primarily aimed at blocking inhibitory signaling by immune cells. An alternative and potentially synergistic approach would involve activation of immune pathways by agonism of stimulatory receptors, such as CD40. Agonistic antibodies, while promising in principle, have encountered significant barriers in clinical trials limited by the systemic toxicity of such approaches. Using a mouse model humanized for both Fc receptors and CD40, we previously demonstrated enhanced antitumor activity with an Fc-modified antibody. We now demonstrate that this model recapitulates the platelet and hepatic toxicities seen with anti-CD40 antibodies in patients, providing a predictive measure of the dose-limiting activity of this approach. We further show that such toxicity can be circumvented and durable systemic antitumor immunity achieved by intratumoral delivery of an Fc-engineered anti-CD40 agonistic antibody. PMID- 30297434 TI - Reducing emergency hospital admissions: a population health complex intervention of an enhanced model of primary care and compassionate communities. AB - BACKGROUND: Reducing emergency admissions to hospital has been a cornerstone of healthcare policy. Little evidence exists to show that systematic interventions across a population have achieved this aim. The authors report the impact of a complex intervention over a 44-month period in Frome, Somerset, on unplanned admissions to hospital. AIM: To evaluate a population health complex intervention of an enhanced model of primary care and compassionate communities on population health improvement and reduction of emergency admissions to hospital. DESIGN AND SETTING: A cohort retrospective study of a complex intervention on all emergency admissions in Frome Medical Practice, Somerset, compared with the remainder of Somerset, from April 2013 to December 2017. METHOD: Patients were identified using broad criteria, including anyone giving cause for concern. Patient-centred goal setting and care planning combined with a compassionate community social approach was implemented broadly across the population of Frome. RESULTS: There was a progressive reduction, by 7.9 cases per quarter (95% confidence interval [CI] = 2.8 to 13.1, P = 0.006), in unplanned hospital admissions across the whole population of Frome during the study period from April 2013 to December 2017, a decrease of 14.0%. At the same time, there was a 28.5% increase in admissions per quarter within Somerset, with a rise in the number of unplanned admissions of 236 per quarter (95% CI = 152 to 320, P<0.001). CONCLUSION: The complex intervention in Frome was associated with highly significant reductions in unplanned admissions to hospital, with a decrease in healthcare costs across the whole population of Frome.

AB - Damage to intestinal epithelial cell (IEC) layers during intestinal inflammation is associated with inflammatory bowel disease. Here we show that the endoribonuclease Regnase-1 controls colon epithelial regeneration by regulating protein kinase mTOR (the mechanistic target of rapamycin kinase) and purine metabolism. During dextran sulfate sodium-induced intestinal epithelial injury and acute colitis, Regnase-1?IEC mice, which lack Regnase-1 specifically in the intestinal epithelium, were resistant to body weight loss, maintained an intact intestinal barrier, and showed increased cell proliferation and decreased epithelial apoptosis. Chronic colitis and tumor progression were also attenuated in Regnase-1?IEC mice. Regnase-1 predominantly regulates mTORC1 signaling. Metabolic analysis revealed that Regnase-1 participates in purine metabolism and energy metabolism during inflammation. Furthermore, increased expression of ectonucleotidases contributed to the resolution of acute inflammation in Regnase 1?IEC mice. These findings provide evidence that Regnase-1 deficiency has beneficial effects on the prevention and/or blocking of intestinal inflammatory disorders. PMID- 30297435 TI - Attitudes towards faecal immunochemical testing in patients at increased risk of colorectal cancer: an online survey of GPs in England. AB - BACKGROUND: There is increasing interest in using a quantitative faecal immunochemical test (FIT) to rule out colorectal cancer (CRC) in patients with high-risk symptoms in primary care. AIM: This study aimed to investigate GPs' attitudes and willingness to use a FIT over an urgent 2-week wait (2WW) referral. DESIGN AND SETTING: A cross-sectional online survey involving 1024 GPs working across England. METHOD: Logistic regression models were used to explore the likelihood of GPs using a FIT instead of a 2WW referral, and reported using odds ratios (ORs) and 95% confidence intervals (95% CIs). RESULTS: Just over one-third of GPs (n = 365) preferred to use a FIT as a rule-out test over a 2WW referral. GPs were more willing if they were: aged 36-45 years (OR 1.59 [95% CI = 1.04 to 2.44]); 46-55 years (OR 1.99 [95% CI = 1.14 to 3.47]); thought a FIT was highly accurate (OR 1.63 [95% CI = 1.16 to 2.29]); thought patients would benefit compared with having a colonoscopy (OR 2.02 [95% CI = 1.46 to 2.79]); and were highly confident about discussing the benefits of a FIT (OR 2.14 [95% CI = 1.46 to 3.16]). GPs were less willing if they had had >10 urgent referrals in the past year (OR 0.62 [95% CI = 0.40 to 0.94]) and thought that longer consultations would be needed (OR 0.61 [95% CI = 0.44 to 0.83]). CONCLUSION: The study findings suggest that the acceptability of using a FIT as a rule-out test in primary care is currently low, with less than half of GPs who perceived the test to be accurate preferring it over colonoscopy. Any potential guideline changes recommending a FIT in patients with high-risk symptoms, instead of urgent referral to rule out CRC, are likely to require intensive supporting educational outreach to increase GP confidence in the accuracy and application of a FIT in this context. PMID- 30297436 TI - Professional resilience in GPs working in areas of socioeconomic deprivation: a qualitative study in primary care. AB - BACKGROUND: GPs working in areas of high socioeconomic deprivation face particular challenges, and are at increased risk of professional burnout. Understanding how GPs working in such areas perceive professional resilience is important in order to recruit and retain a GP workforce in these areas. AIM: To understand how GPs working in areas of high socioeconomic deprivation consider professional resilience. DESIGN AND SETTING: A qualitative study of GPs practising in deprived areas within one primary care region of England. METHOD: In total, 14 individual interviews and one focus group of eight participants were undertaken, with sampling to data saturation. A framework approach was used for data analysis. RESULTS: Participants described three key themes relating to resilience. First, resilience was seen as involving flexibility and adaptability. This involved making trade-offs in order to keep going, even if this was imperfect. Second, resilience was enacted through teams rather than through individual strength. Third, resilience required the integration of personal and professional values rather than keeping the two separate. This dynamic adaptive view, with an emphasis on the importance of individuals within teams rather than in isolation, contrasts with the discourse of resilience as a personal characteristic, which should be strengthened at the individual level. CONCLUSION: Professional resilience is about more than individual strength. Policies to promote professional resilience, particularly in settings such as areas of high socioeconomic deprivation, must recognise the importance of flexibility, adaptability, working as teams, and successful integration between work and personal values. PMID- 30297437 TI - GP follow-up after first diagnosing psychological problems among adolescents: a nationwide register-based study. AB - BACKGROUND: Psychological problems are common among adolescents. Many GPs consider these problems challenging, even after diagnosis. AIM: To explore how Norwegian GPs follow-up patients after a first diagnosis of a psychological problem at age 15-16 years. DESIGN AND SETTING: Nationwide longitudinal, register based study using claims data for all GPs in the national list patient system, and for adolescents born in 1993 and 1994 (n = 129 499). METHOD: National databases and registers were used to determine how many adolescents received a first diagnosis of a psychological problem in a GP consultation at age 15 or 16 years. Further consultations, collaborative contacts in primary care, and referrals to secondary care during the year after diagnosis were then identified and used as outcomes in regression analyses to investigate associations with initial diagnosis, parental education, and GP characteristics. RESULTS: In total, 6809 (5.3%) adolescents received a first diagnosis of a psychological problem in a GP consultation at age 15 or 16 years. Internalising problems constituted 50.5% of initial diagnoses among females and 28.8% among males. Behaviour and attention problems accounted for 21.3% for females and 45.0% for males. In total, 46.6% of females and 39.9% of males had >=1 follow-up consultation, and 32.8% of females and 27.0% of males were referred to secondary care. GPs reported primary care collaboration for 22.1% of females and 19.1% of males. GPs with larger patient lists had higher referral rates, but collaborated less within primary care. Males with a male GP had more follow-up consultations than males with a female GP. CONCLUSION: GP follow-up after diagnosing psychological problems among adolescents is limited, but predominantly comprised referrals and some multidisciplinary cooperation. GP follow-up consultations should be studied more thoroughly, and the role of GPs warrants further policy discussions. PMID- 30297438 TI - Tight junction proteins in gastrointestinal and liver disease. AB - Over the past two decades a growing body of evidence has demonstrated an important role of tight junction (TJ) proteins in the physiology and disease biology of GI and liver disease. On one side, TJ proteins exert their functional role as integral proteins of TJs in forming barriers in the gut and the liver. Furthermore, TJ proteins can also be expressed outside TJs where they play important functional roles in signalling, trafficking and regulation of gene expression. A hallmark of TJ proteins in disease biology is their functional role in epithelial-to-mesenchymal transition. A causative role of TJ proteins has been established in the pathogenesis of colorectal cancer and gastric cancer. Among the best characterised roles of TJ proteins in liver disease biology is their function as cell entry receptors for HCV-one of the most common causes of hepatocellular carcinoma. At the same time TJ proteins are emerging as targets for novel therapeutic approaches for GI and liver disease. Here we review our current knowledge of the role of TJ proteins in the pathogenesis of GI and liver disease biology and discuss their potential as therapeutic targets.

PMID- 30297439 TI - Long term adjuvant endocrine therapy and risk of cardiovascular disease in female breast cancer survivors: systematic review. AB - OBJECTIVE: To investigate the effect of endocrine therapies on a wide range of specific clinical cardiovascular disease outcomes in women with a history of non metastatic breast cancer. DESIGN: Systematic review and meta-analysis of randomised controlled trials and observational studies. DATA SOURCES: Medline and Embase up until June 2018. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Studies were included if they investigated the risk of a specific cardiovascular disease outcome associated with use of either tamoxifen or an aromatase inhibitor, or compared the two treatments, in women with a history of non-metastatic breast cancer. APPRAISAL AND DATA EXTRACTION: Relevant studies were originally identified and results extracted by one researcher, with a full replication of the study identification process by a combination of two other researchers. The Cochrane Collaboration's tool for assessing risk of bias was used to assess risk of bias in randomised controlled trials, and this tool was adapted to assess risk of bias in observational studies. RESULTS: 26 studies were identified, with results for seven specific cardiovascular disease outcomes (venous thromboembolism, myocardial infarction, stroke, angina, heart failure, arrhythmia, and peripheral vascular disease). Results suggested an increased risk of venous thromboembolism in tamoxifen users compared with both non-users and aromatase inhibitor users. Results were also consistent with a higher risk of the vascular diseases myocardial infarction and angina in aromatase inhibitor users compared with tamoxifen users, but there was also a suggestion that this may be partly driven by a protective effect of tamoxifen on these outcomes. Data were limited, and evidence was generally inconsistent for all other cardiovascular disease outcomes. CONCLUSION: This review has collated substantial randomised controlled trial and observational evidence on the effect of endocrine therapies on several specific cardiovascular disease outcomes including venous thromboembolism and myocardial infarction, progressing knowledge. Although the choice of aromatase inhibitor or tamoxifen will primarily be based on the effectiveness against the recurrence of breast cancer, this review shows that the individual patient's risk of venous or arterial vascular disease should be an important secondary consideration. SYSTEMATIC REVIEW REGISTRATION: Prospero CRD42017065944. PMID- 30297442 TI - Can infant sleeping bags be recommended by medical professionals as protection against sudden infant death syndrome? AB - : Clinical scenario: A mother brought her infant to the hospital with bronchiolitis and incidentally asked if I would recommend the use of infant sleeping bags to protect against Sudden Infant Death Syndrome as several of her friends use them. Structured question: Can infant sleeping bags be recommended by medical professionals as protective against Sudden Infant Death Syndrome? METHODS: A literature search was performed. Trials were included if they had an English version available and the papers examined the impact that sleeping bag use had on risk of SIDS or its risk factors. Cochrane Library search found eight trials, two of which were found to meet inclusion criteria. MEDLINE was searched using the search terms ((baby sleeping bag) OR infant sleeping bag) OR cotton sleeping sack. Forty-seven papers were found, two of which were found to meet the inclusion criteria, one of which had already been found in the Cochrane Library search. One further paper was found through searching citations of the papers included. DISCUSSION: Sleeping bags are used in 48-95% of infants in the UK and advocated for by the Lullaby Trust for their safety in the prevention of SIDS. The case control studies included found that sleeping bags are as safe, if not safer than other bedding when examining SIDS as an outcome. For sleeping bags to be safe they must be well made and appropriately used, which includes the correct size, Tog, clothing and other bedding for bedroom temperature.

AB - OBJECTIVE: To identify if the educational trajectories of preterm infants differ from those of their term peers. DESIGN: This work is based on the Avon Longitudinal Study of Parents and Children (ALSPAC). Educational measures were categorised into 10 deciles to allow comparison of measures across time periods. Gestational age was categorised as preterm (23-36 weeks) or term (37-42 weeks). Multilevel mixed-effects linear regression models were derived to examine the trajectories of decile scores across the study period. Gestational group was added as an interaction term to assess if the trajectory between educational measures varied between preterm and term infants. Adjustment for possible confounders was performed. SUBJECTS: The final dataset contained information on 12 586 infants born alive at between 23 weeks and 42 weeks of gestation. MAIN OUTCOME MEASURES: UK mandatory educational assessments (SATs) scores throughout educational journal (including final GCSE results at 16 years of age). RESULTS: Preterm infants had on average lower Key Stage (KS) scores than term children ( 0.46 (-0.84 to -0.07)). However, on average, they gained on their term peers in each progressive measure (0.10 (0.01 to 0.19)), suggesting 'catch up' during the first few years at school. Preterm infants appeared to exhibit the increase in decile scores mostly between KS1 and KS2 (p=0.005) and little between KS2 and KS3 (p=0.182) or KS3 and KS4 (p=0.149). CONCLUSIONS: This work further emphasises the importance of early schooling and environment in these infants and suggests that support, long after the premature birth, may have additional benefits.

PMID- 30297453 TI - PRP4KA, a Putative Spliceosomal Protein Kinase, Is Important for Alternative Splicing and Development in Arabidopsis thaliana. AB - Splicing of precursor messenger RNAs (pre-mRNAs) is an essential step in the expression of most eukaryotic genes. Both constitutive splicing and alternative splicing, which produces multiple messenger RNA (mRNA) isoforms from a single primary transcript, are modulated by reversible protein phosphorylation. Although the plant splicing machinery is known to be a target for phosphorylation, the protein kinases involved remain to be fully defined. We report here the identification of pre-mRNA processing 4 (PRP4) KINASE A (PRP4KA) in a forward genetic screen based on an alternatively spliced GFP reporter gene in Arabidopsis thaliana (Arabidopsis). Prp4 kinase is the first spliceosome-associated kinase shown to regulate splicing in fungi and mammals but it has not yet been studied in plants. In the same screen we identified mutants defective in SAC3A, a putative mRNA export factor that is highly coexpressed with PRP4KA in Arabidopsis Whereas the sac3a mutants appear normal, the prp4ka mutants display a pleiotropic phenotype featuring atypical rosettes, late flowering, tall final stature, reduced branching, and lowered seed set. Analysis of RNA-sequencing data from prp4ka and sac3a mutants identified widespread and partially overlapping perturbations in alternative splicing in the two mutants. Quantitative phosphoproteomic profiling of a prp4ka mutant detected phosphorylation changes in several serine/arginine-rich proteins, which regulate constitutive and alternative splicing, and other splicing-related factors. Tests of PRP4KB, the paralog of PRP4KA, indicated that the two genes are not functionally redundant. The results demonstrate the importance of PRP4KA for alternative splicing and plant phenotype, and suggest that PRP4KA may influence alternative splicing patterns by phosphorylating a subset of splicing regulators. PMID- 30297454 TI - Combinatorial Approach for Complex Disorder Prediction: Case Study of Neurodevelopmental Disorders. AB - Early prediction of complex disorders (e.g., autism and other neurodevelopmental disorders) is one of the fundamental goals of precision medicine and personalized genomics. An early prediction of complex disorders can improve the prognosis, increase the effectiveness of interventions and treatments, and enhance the life quality of affected patients. Considering the genetic heritability of neurodevelopmental disorders, we are proposing a novel framework for utilizing rare coding variation for early prediction of these disorders in subset of affected samples. We provide a combinatorial framework for addressing this problem, denoted as Odin (Oracle for DIsorder predictioN), to make a prediction for a small, yet significant, subset of affected cases while having very low false positive rate (FPR) prediction for unaffected samples. Odin also takes advantage of the available functional information (e.g., pairwise coexpression of genes during brain development) to increase the prediction power beyond genes with recurrent variants. Application of our method accurately recovers an additional 8% of autism cases without any severe variant in known recurrent mutated genes with a <1% FPR. Furthermore, Odin predicted a set of 391 genes that severe variants in these genes can cause autism or other developmental delay disorders. Approaches such as the one presented in this paper are needed to translate the biomedical discoveries into actionable items by clinicians. Odin is publicly available at https://github.com/HormozdiariLab/Odin. PMID- 30297457 TI - GPs and technology: the good, the bad, and the ugly babies. PMID- 30297456 TI - Reconfigured Cyanogenic Glucoside Biosynthesis in Eucalyptus cladocalyx Involves a Cytochrome P450 CYP706C55. AB - Cyanogenic glucosides are a class of specialized metabolites widespread in the plant kingdom. Cyanogenic glucosides are alpha-hydroxynitriles, and their hydrolysis releases toxic hydrogen cyanide, providing an effective chemical defense against herbivores. Eucalyptus cladocalyx is a cyanogenic tree, allocating up to 20% of leaf nitrogen to the biosynthesis of the cyanogenic monoglucoside, prunasin. Here, mass spectrometry analyses of E. cladocalyx tissues revealed spatial and ontogenetic variations in prunasin content, as well as the presence of the cyanogenic diglucoside amygdalin in flower buds and flowers. The identification and biochemical characterization of the prunasin biosynthetic enzymes revealed a unique enzyme configuration for prunasin production in E. cladocalyx This result indicates that a multifunctional cytochrome P450 (CYP), CYP79A125, catalyzes the initial conversion of l phenylalanine into its corresponding aldoxime, phenylacetaldoxime; a function consistent with other members of the CYP79 family. In contrast to the single multifunctional CYP known from other plant species, the conversion of phenylacetaldoxime to the alpha-hydroxynitrile, mandelonitrile, is catalyzed by two distinct CYPs. CYP706C55 catalyzes the dehydration of phenylacetaldoxime, an unusual CYP reaction. The resulting phenylacetonitrile is subsequently hydroxylatedby CYP71B103 to form mandelonitrile. The final glucosylation step to yield prunasin is catalyzed by a UDP-glucosyltransferase, UGT85A59. Members of the CYP706 family have not been reported previously to participate in the biosynthesis of cyanogenic glucosides, and the pathway structure in E. cladocalyx represents an example of convergent evolution in the biosynthesis of cyanogenic glucosides in plants. PMID- 30297458 TI - Long-Term Survival in Patients Responding to Anti-PD-1/PD-L1 Therapy and Disease Outcome upon Treatment Discontinuation. AB - Purpose: Anti-PD-(L)1 can provide overall survival (OS) benefits over conventional treatments for patients with many different cancer types. However, the long-term outcome of cancer patients responding to these therapies remains unknown. This study is an exploratory study that aimed to describe the long-term survival of patients responding to anti-PD-(L)1 monotherapy across multiple cancer types.Experimental Design: Data from patients treated with an anti-PD-(L)1 monotherapy in a phase I trial at Gustave Roussy were retrospectively analyzed over a period of 5 years. All cancer types (n = 19) were included. Clinical and biological factors associated with response, long-term survival, and secondary refractory disease were studied.Results: Among 262 eligible patients, the overall objective response rate was 29%. The median progression-free survival of responder patients (RP) at 3 months was 30 months, and the median OS of RP was not reached after a median follow-up of 34 months. In RPs, 3- and 5-year OS percentages were 84% and 64%, respectively. No death occurred in the 21 complete responders (CR) during the overall follow-up. However, many partial responders (PR) showed subsequent tumor relapses to treatment. Long responders (response >=2 years) represented 11.8% of the overall population. These findings should be validated in further prospective studies.Conclusions: There are currently no differences in therapeutic strategies between CRs and PRs to anti-PD-(L)1. We found a striking difference in OS between these two types of responses. Our results are in favor of evaluating patient stratification strategies and intensification of treatments when tumor lesions of a partial responder to immunotherapy stop improving.

AB - Proper balance between the repair of DNA double-strand breaks (DSBs) by homologous recombination and nonhomologous end-joining is critical for maintaining genome integrity and preventing tumorigenesis. This balance is regulated and fine-tuned by a variety of factors, including cell cycle and the chromatin environment. The histone acetyltransferase TIP60 was previously shown to suppress pathologic end-joining and promote homologous recombination. However, it is unknown how regulatory post-translational modifications impact TIP60 acetyltransferase activity to influence the outcome of DSB responses. In this study we report that phosphorylation of TIP60 on serines 90 and 86 is important for limiting the accumulation of the pro-end-joining factor 53BP1 at DSBs in S and G2 cell cycle phases. Mutation of these sites disrupts histone acetylation changes in response to DNA damage, BRCA1 localization to DSBs, and PARP inhibitor resistance. These findings reveal that phosphorylation directs TIP60-dependent acetylation to promote homologous recombination and maintain genome stability. PMID- 30297455 TI - Elucidation of the Amygdalin Pathway Reveals the Metabolic Basis of Bitter and Sweet Almonds (Prunus dulcis). AB - Almond (Prunus dulcis) is the principal Prunus species in which the consumed and thus commercially important part of the fruit is the kernel. As a result of continued selection, the vast majority of almonds have a nonbitter kernel. However, in the field, there are trees carrying bitter kernels, which are toxic to humans and, consequently, need to be removed. The toxicity of bitter almonds is caused by the accumulation of the cyanogenic diglucoside amygdalin, which releases toxic hydrogen cyanide upon hydrolysis. In this study, we identified and characterized the enzymes involved in the amygdalin biosynthetic pathway: PdCYP79D16 and PdCYP71AN24 as the cytochrome P450 (CYP) enzymes catalyzing phenylalanine-to-mandelonitrile conversion, PdUGT94AF3 as an additional monoglucosyl transferase (UGT) catalyzing prunasin formation, and PdUGT94AF1 and PdUGT94AF2 as the two enzymes catalyzing amygdalin formation from prunasin. This was accomplished by constructing a sequence database containing UGTs known, or predicted, to catalyze a beta(1->6)-O-glycosylation reaction and a Basic Local Alignment Search Tool search of the draft version of the almond genome versus these sequences. Functional characterization of candidate genes was achieved by transient expression in Nicotiana benthamiana Reverse transcription quantitative polymerase chain reaction demonstrated that the expression of PdCYP79D16 and PdCYP71AN24 was not detectable or only reached minute levels in the sweet almond genotype during fruit development, while it was high and consistent in the bitter genotype. Therefore, the basis for the sweet kernel phenotype is a lack of expression of the genes encoding the two CYPs catalyzing the first steps in amygdalin biosynthesis. PMID- 30297460 TI - New insights into the variability of the tropical land carbon cycle from the El Nino of 2015/2016. PMID- 30297462 TI - A successful prediction of the record CO2 rise associated with the 2015/2016 El Nino. AB - In early 2016, we predicted that the annual rise in carbon dioxide concentration at Mauna Loa would be the largest on record. Our forecast used a statistical relationship between observed and forecast sea surface temperatures in the Nino 3.4 region and the annual CO2 rise. Here, we provide a formal verification of that forecast. The observed rise of 3.4 ppm relative to 2015 was within the forecast range of 3.15 +/- 0.53 ppm, so the prediction was successful. A global terrestrial biosphere model supports the expectation that the El Nino weakened the tropical land carbon sink. We estimate that the El Nino contributed approximately 25% to the record rise in CO2, with 75% due to anthropogenic emissions. The 2015/2016 CO2 rise was greater than that following the previous large El Nino in 1997/1998, because anthropogenic emissions had increased. We had also correctly predicted that 2016 would be the first year with monthly mean CO2 above 400 ppm all year round. We now estimate that atmospheric CO2 at Mauna Loa would have remained above 400 ppm all year round in 2016 even if the El Nino had not occurred, contrary to our previous expectations based on a simple extrapolation of previous trends.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297461 TI - Spatio-temporal patterns of thermal anomalies and drought over tropical forests driven by recent extreme climatic anomalies. AB - The recent 2015-2016 El Nino (EN) event was considered as strong as the EN in 1997-1998. Given such magnitude, it was expected to result in extreme warming and moisture anomalies in tropical areas. Here we characterize the spatial patterns of temperature anomalies and drought over tropical forests, including tropical South America (Amazonia), Africa and Asia/Indonesia during the 2015-2016 EN event. These spatial patterns of warming and drought are compared with those observed in previous strong EN events (1982-1983 and 1997-1998) and other moderate to strong EN events (e.g. 2004-2005 and 2009-2010). The link between the spatial patterns of drought and sea surface temperature anomalies in the central and eastern Pacific is also explored. We show that indeed the EN2015-2016 led to unprecedented warming compared to the other EN events over Amazonia, Africa and Indonesia, as a consequence of the background global warming trend. Anomalous accumulated extreme drought area over Amazonia was found during EN2015-2016, but this value may be closer to extreme drought area extents in the other two EN events in 1982-1983 and 1997-1998. Over Africa, datasets disagree, and it is difficult to conclude which EN event led to the highest accumulated extreme drought area. Our results show that the highest values of accumulated drought area over Africa were obtained in 2015-2016 and 1997-1998, with a long-term drying trend not observed over the other tropical regions. Over Indonesia, all datasets suggest that EN 1982-1983 and EN 1997-1998 (or even the drought of 2005) led to a higher extreme drought area than EN2015-2016. Uncertainties in precipitation datasets hinder consistent estimates of drought severity over tropical regions, and improved reanalysis products and station records are required.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297464 TI - History of El Nino impacts on the global carbon cycle 1957-2017: a quantification from atmospheric CO2 data. AB - Interannual variations in the large-scale net ecosystem exchange (NEE) of CO2 between the terrestrial biosphere and the atmosphere were estimated for 1957-2017 from sustained measurements of atmospheric CO2 mixing ratios. As the observations are sparse in the early decades, available records were combined into a 'quasi homogeneous' dataset based on similarity in their signals, to minimize spurious variations from beginning or ending data records. During El Nino events, CO2 is anomalously released from the tropical band, and a few months later also in the northern extratropical band. This behaviour can approximately be represented by a linear relationship of the NEE anomalies and local air temperature anomalies, with sensitivity coefficients depending on geographical location and season. The apparent climate sensitivity of global total NEE against variations in pan tropically averaged annual air temperature slowly changed over time during the 1957-2017 period, first increasing (though less strongly than in previous studies) but then decreasing again. However, only part of this change can be attributed to actual changes in local physiological or ecosystem processes, the rest probably arising from shifts in the geographical area of dominating temperature variations.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297463 TI - Tropical land carbon cycle responses to 2015/16 El Nino as recorded by atmospheric greenhouse gas and remote sensing data. AB - The outstanding tropical land climate characteristic over the past decades is rapid warming, with no significant large-scale precipitation trends. This warming is expected to continue but the effects on tropical vegetation are unknown. El Nino-related heat peaks may provide a test bed for a future hotter world. Here we analyse tropical land carbon cycle responses to the 2015/16 El Nino heat and drought anomalies using an atmospheric transport inversion. Based on the global atmospheric CO2 and fossil fuel emission records, we find no obvious signs of anomalously large carbon release compared with earlier El Nino events, suggesting resilience of tropical vegetation. We find roughly equal net carbon release anomalies from Amazonia and tropical Africa, approximately 0.5 PgC each, and smaller carbon release anomalies from tropical East Asia and southern Africa. Atmospheric CO anomalies reveal substantial fire carbon release from tropical East Asia peaking in October 2015 while fires contribute only a minor amount to the Amazonian carbon flux anomaly. Anomalously large Amazonian carbon flux release is consistent with downregulation of primary productivity during peak negative near-surface water anomaly (October 2015 to March 2016) as diagnosed by solar-induced fluorescence. Finally, we find an unexpected anomalous positive flux to the atmosphere from tropical Africa early in 2016, coincident with substantial CO release.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297466 TI - Monitoring emissions from the 2015 Indonesian fires using CO satellite data. AB - Southeast Asia, in particular Indonesia, has periodically struggled with intense fire events. These events convert substantial amounts of carbon stored as peat to atmospheric carbon dioxide (CO2) and significantly affect atmospheric composition on a regional to global scale. During the recent 2015 El Nino event, peat fires led to strong enhancements of carbon monoxide (CO), an air pollutant and well known tracer for biomass burning. These enhancements were clearly observed from space by the Infrared Atmospheric Sounding Interferometer (IASI) and the Measurements of Pollution in the Troposphere (MOPITT) instruments. We use these satellite observations to estimate CO fire emissions within an inverse modelling framework. We find that the derived CO emissions for each sub-region of Indonesia and Papua are substantially different from emission inventories, highlighting uncertainties in bottom-up estimates. CO fire emissions based on either MOPITT or IASI have a similar spatial pattern and evolution in time, and a 10% uncertainty based on a set of sensitivity tests we performed. Thus, CO satellite data have a high potential to complement existing operational fire emission estimates based on satellite observations of fire counts, fire radiative power and burned area, in better constraining fire occurrence and the associated conversion of peat carbon to atmospheric CO2 A total carbon release to the atmosphere of 0.35-0.60 Pg C can be estimated based on our results.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297465 TI - Impact of the 2015/2016 El Nino on the terrestrial carbon cycle constrained by bottom-up and top-down approaches. AB - Evaluating the response of the land carbon sink to the anomalies in temperature and drought imposed by El Nino events provides insights into the present-day carbon cycle and its climate-driven variability. It is also a necessary step to build confidence in terrestrial ecosystems models' response to the warming and drying stresses expected in the future over many continents, and particularly in the tropics. Here we present an in-depth analysis of the response of the terrestrial carbon cycle to the 2015/2016 El Nino that imposed extreme warming and dry conditions in the tropics and other sensitive regions. First, we provide a synthesis of the spatio-temporal evolution of anomalies in net land-atmosphere CO2 fluxes estimated by two in situ measurements based on atmospheric inversions and 16 land-surface models (LSMs) from TRENDYv6. Simulated changes in ecosystem productivity, decomposition rates and fire emissions are also investigated. Inversions and LSMs generally agree on the decrease and subsequent recovery of the land sink in response to the onset, peak and demise of El Nino conditions and point to the decreased strength of the land carbon sink: by 0.4-0.7 PgC yr-1 (inversions) and by 1.0 PgC yr-1 (LSMs) during 2015/2016. LSM simulations indicate that a decrease in productivity, rather than increase in respiration, dominated the net biome productivity anomalies in response to ENSO throughout the tropics, mainly associated with prolonged drought conditions.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297467 TI - Tree growth and stem carbon accumulation in human-modified Amazonian forests following drought and fire. AB - Human-modified forests are an ever-increasing feature across the Amazon Basin, but little is known about how stem growth is influenced by extreme climatic events and the resulting wildfires. Here we assess for the first time the impacts of human-driven disturbance in combination with El Nino-mediated droughts and fires on tree growth and carbon accumulation. We found that after 2.5 years of continuous measurements, there was no difference in stem carbon accumulation between undisturbed and human-modified forests. Furthermore, the extreme drought caused by the El Nino did not affect carbon accumulation rates in surviving trees. In recently burned forests, trees grew significantly more than in unburned ones, regardless of their history of previous human disturbance. Wood density was the only significant factor that helped explain the difference in growth between trees in burned and unburned forests, with low wood-density trees growing significantly more in burned sites. Our results suggest stem carbon accumulation is resistant to human disturbance and one-off extreme drought events, and it is stimulated immediately after wildfires. However, these results should be seen with caution-without accounting for carbon losses, recruitment and longer-term changes in species composition, we cannot fully understand the impacts of drought and fire in the carbon balance of human-modified forests.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297468 TI - Short-term effects of drought on tropical forest do not fully predict impacts of repeated or long-term drought: gas exchange versus growth. AB - Are short-term responses by tropical rainforest to drought (e.g. during El Nino) sufficient to predict changes over the long-term, or from repeated drought? Using the world's only long-term (16-year) drought experiment in tropical forest we examine predictability from short-term measurements (1-2 years). Transpiration was maximized in droughted forest: it consumed all available throughfall throughout the 16 years of study. Leaf photosynthetic capacity [Formula: see text] was maintained, but only when averaged across tree size groups. Annual transpiration in droughted forest was less than in control, with initial reductions (at high biomass) imposed by foliar stomatal control. Tree mortality increased after year three, leading to an overall biomass loss of 40%; over the long-term, the main constraint on transpiration was thus imposed by the associated reduction in sapwood area. Altered tree mortality risk may prove predictable from soil and plant hydraulics, but additional monitoring is needed to test whether future biomass will stabilize or collapse. Allocation of assimilate differed over time: stem growth and reproductive output declined in the short-term, but following mortality-related changes in resource availability, both showed long-term resilience, with partial or full recovery. Understanding and simulation of these phenomena and related trade-offs in allocation will advance more effectively through greater use of optimization and probabilistic modelling approaches.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297469 TI - Quantifying immediate carbon emissions from El Nino-mediated wildfires in humid tropical forests. AB - Wildfires produce substantial CO2 emissions in the humid tropics during El Nino mediated extreme droughts, and these emissions are expected to increase in coming decades. Immediate carbon emissions from uncontrolled wildfires in human-modified tropical forests can be considerable owing to high necromass fuel loads. Yet, data on necromass combustion during wildfires are severely lacking. Here, we evaluated necromass carbon stocks before and after the 2015-2016 El Nino in Amazonian forests distributed along a gradient of prior human disturbance. We then used Landsat-derived burn scars to extrapolate regional immediate wildfire CO2 emissions during the 2015-2016 El Nino. Before the El Nino, necromass stocks varied significantly with respect to prior disturbance and were largest in undisturbed primary forests (30.2 +/- 2.1 Mg ha-1, mean +/- s.e.) and smallest in secondary forests (15.6 +/- 3.0 Mg ha-1). However, neither prior disturbance nor our proxy of fire intensity (median char height) explained necromass losses due to wildfires. In our 6.5 million hectare (6.5 Mha) study region, almost 1 Mha of primary (disturbed and undisturbed) and 20 000 ha of secondary forest burned during the 2015-2016 El Nino. Covering less than 0.2% of Brazilian Amazonia, these wildfires resulted in expected immediate CO2 emissions of approximately 30 Tg, three to four times greater than comparable estimates from global fire emissions databases. Uncontrolled understorey wildfires in humid tropical forests during extreme droughts are a large and poorly quantified source of CO2 emissions.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297471 TI - Inter-comparison and assessment of gridded climate products over tropical forests during the 2015/2016 El Nino. AB - To understand the impacts of extreme climate events, it is first necessary to understand the spatio-temporal characteristics of the event. Gridded climate products are frequently used to describe climate patterns but have been shown to perform poorly over data-sparse regions such as tropical forests. Often, they are uncritically employed in a wide range of studies linking tropical forest processes to large-scale climate variability. Here, we conduct an inter comparison and assessment of near-surface air temperature fields supplied by four state-of-the-art reanalysis products, along with precipitation estimates supplied by four merged satellite-gauge rainfall products. Firstly, spatio-temporal patterns of temperature and precipitation anomalies during the 2015-2016 El Nino are shown for each product to characterize the impact of the El Nino on the tropical forest biomes of Equatorial Africa, Southeast Asia and South America. Using meteorological station data, a two-stage assessment is then conducted to determine which products most reliably model tropical climates during the 2015 2016 El Nino, and which perform best over the longer-term satellite observation period (1980-2016). Results suggest that eastern Amazonia, parts of the Congo Basin and mainland Southeast Asia all experienced significant monthly mean temperature anomalies during the El Nino, while northeastern Amazonia, eastern Borneo and southern New Guinea experienced significant precipitation deficits. Our results suggest ERA-Interim and MERRA2 are the most reliable air temperature datasets, while TRMM 3B42 V7 and CHIRPS v2.0 are the best-performing rainfall datasets.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297470 TI - Modelling tropical forest responses to drought and El Nino with a stomatal optimization model based on xylem hydraulics. AB - The current generation of dynamic global vegetation models (DGVMs) lacks a mechanistic representation of vegetation responses to soil drought, impairing their ability to accurately predict Earth system responses to future climate scenarios and climatic anomalies, such as El Nino events. We propose a simple numerical approach to model plant responses to drought coupling stomatal optimality theory and plant hydraulics that can be used in dynamic global vegetation models (DGVMs). The model is validated against stand-scale forest transpiration (E) observations from a long-term soil drought experiment and used to predict the response of three Amazonian forest sites to climatic anomalies during the twentieth century. We show that our stomatal optimization model produces realistic stomatal responses to environmental conditions and can accurately simulate how tropical forest E responds to seasonal, and even long term soil drought. Our model predicts a stronger cumulative effect of climatic anomalies in Amazon forest sites exposed to soil drought during El Nino years than can be captured by alternative empirical drought representation schemes. The contrasting responses between our model and empirical drought factors highlight the utility of hydraulically-based stomatal optimization models to represent vegetation responses to drought and climatic anomalies in DGVMs.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297472 TI - The role of satellite observations in understanding the impact of El Nino on the carbon cycle: current capabilities and future opportunities. AB - The 2015/2016 El Nino was the first major climate variation when there were a range of satellite observations that simultaneously observed land, ocean and atmospheric properties associated with the carbon cycle. These data are beginning to provide new insights into the varied responses of land ecosystems to El Nino, but we are far from fully exploiting the information embodied by these data. Here, we briefly review the atmospheric and terrestrial satellite data that are available to study the carbon cycle. We also outline recommendations for future research, particularly the closer integration of satellite data with forest biometric datasets that provide detailed information about carbon dynamics on a range of timescales.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297473 TI - Widespread reduction in sun-induced fluorescence from the Amazon during the 2015/2016 El Nino. AB - The tropical carbon balance dominates year-to-year variations in the CO2 exchange with the atmosphere through photosynthesis, respiration and fires. Because of its high correlation with gross primary productivity (GPP), observations of sun induced fluorescence (SIF) are of great interest. We developed a new remotely sensed SIF product with improved signal-to-noise in the tropics, and use it here to quantify the impact of the 2015/2016 El Nino Amazon drought. We find that SIF was strongly suppressed over areas with anomalously high temperatures and decreased levels of water in the soil. SIF went below its climatological range starting from the end of the 2015 dry season (October) and returned to normal levels by February 2016 when atmospheric conditions returned to normal, but well before the end of anomalously low precipitation that persisted through June 2016. Impacts were not uniform across the Amazon basin, with the eastern part experiencing much larger (10-15%) SIF reductions than the western part of the basin (2-5%). We estimate the integrated loss of GPP relative to eight previous years to be 0.34-0.48 PgC in the three-month period October-November-December 2015.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297474 TI - The impact of the 2015/2016 El Nino on global photosynthesis using satellite remote sensing. AB - The El Nino-Southern Oscillation exerts a large influence on global climate regimes and on the global carbon cycle. Although El Nino is known to be associated with a reduction of the global total land carbon sink, results based on prognostic models or measurements disagree over the relative contribution of photosynthesis to the reduced sink. Here, we provide an independent remote sensing-based analysis on the impact of the 2015-2016 El Nino on global photosynthesis using six global satellite-based photosynthesis products and a global solar-induced fluorescence (SIF) dataset. An ensemble of satellite-based photosynthesis products showed a negative anomaly of -0.7 +/- 1.2 PgC in 2015, but a slight positive anomaly of 0.05 +/- 0.89 PgC in 2016, which when combined with observations of the growth rate of atmospheric carbon dioxide concentrations suggests that the reduction of the land residual sink was likely dominated by photosynthesis in 2015 but by respiration in 2016. The six satellite-based products unanimously identified a major photosynthesis reduction of -1.1 +/- 0.52 PgC from savannahs in 2015 and 2016, followed by a highly uncertain reduction of 0.22 +/- 0.98 PgC from rainforests. Vegetation in the Northern Hemisphere enhanced photosynthesis before and after the peak El Nino, especially in grasslands (0.33 +/- 0.13 PgC). The patterns of satellite-based photosynthesis ensemble mean were corroborated by SIF, except in rainforests and South America, where the anomalies of satellite-based photosynthesis products also diverged the most. We found the inter-model variation of photosynthesis estimates was strongly related to the discrepancy between moisture forcings for models. These results highlight the importance of considering multiple photosynthesis proxies when assessing responses to climatic anomalies.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297476 TI - Vulnerability of Amazonian forests to repeated droughts. AB - Extreme droughts have been recurrent in the Amazon over the past decades, causing socio-economic and environmental impacts. Here, we investigate the vulnerability of Amazonian forests, both undisturbed and human-modified, to repeated droughts. We defined vulnerability as a measure of (i) exposure, which is the degree to which these ecosystems were exposed to droughts, and (ii) its sensitivity, measured as the degree to which the drought has affected remote sensing-derived forest greenness. The exposure was calculated by assessing the meteorological drought, using the standardized precipitation index (SPI) and the maximum cumulative water deficit (MCWD), which is related to vegetation water stress, from 1981 to 2016. The sensitivity was assessed based on the enhanced vegetation index anomalies (AEVI), derived from the newly available Moderate Resolution Imaging Spectroradiometer (MODIS)/Multi-Angle Implementation of Atmospheric Correction algorithm (MAIAC) product, from 2003 to 2016, which is indicative of forest's photosynthetic capacity. We estimated that 46% of the Brazilian Amazon biome was under severe to extreme drought in 2015/2016 as measured by the SPI, compared with 16% and 8% for the 2009/2010 and 2004/2005 droughts, respectively. The most recent drought (2015/2016) affected the largest area since the drought of 1981. Droughts tend to increase the variance of the photosynthetic capacity of Amazonian forests as based on the minimum and maximum AEVI analysis. However, the area showing a reduction in photosynthetic capacity prevails in the signal, reaching more than 400 000 km2 of forests, four orders of magnitude larger than areas with AEVI enhancement. Moreover, the intensity of the negative AEVI steadily increased from 2005 to 2016. These results indicate that during the analysed period drought impacts were being exacerbated through time. Forests in the twenty-first century are becoming more vulnerable to droughts, with larger areas intensively and negatively responding to water shortage in the region.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297475 TI - ENSO Drives interannual variation of forest woody growth across the tropics. AB - Meteorological extreme events such as El Nino events are expected to affect tropical forest net primary production (NPP) and woody growth, but there has been no large-scale empirical validation of this expectation. We collected a large high-temporal resolution dataset (for 1-13 years depending upon location) of more than 172 000 stem growth measurements using dendrometer bands from across 14 regions spanning Amazonia, Africa and Borneo in order to test how much month-to month variation in stand-level woody growth of adult tree stems (NPPstem) can be explained by seasonal variation and interannual meteorological anomalies. A key finding is that woody growth responds differently to meteorological variation between tropical forests with a dry season (where monthly rainfall is less than 100 mm), and aseasonal wet forests lacking a consistent dry season. In seasonal tropical forests, a high degree of variation in woody growth can be predicted from seasonal variation in temperature, vapour pressure deficit, in addition to anomalies of soil water deficit and shortwave radiation. The variation of aseasonal wet forest woody growth is best predicted by the anomalies of vapour pressure deficit, water deficit and shortwave radiation. In total, we predict the total live woody production of the global tropical forest biome to be 2.16 Pg C yr-1, with an interannual range 1.96-2.26 Pg C yr-1 between 1996-2016, and with the sharpest declines during the strong El Nino events of 1997/8 and 2015/6. There is high geographical variation in hotspots of El Nino-associated impacts, with weak impacts in Africa, and strongly negative impacts in parts of Southeast Asia and extensive regions across central and eastern Amazonia. Overall, there is high correlation (r = -0.75) between the annual anomaly of tropical forest woody growth and the annual mean of the El Nino 3.4 index, driven mainly by strong correlations with anomalies of soil water deficit, vapour pressure deficit and shortwave radiation.This article is part of the discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297477 TI - Drought-induced Amazonian wildfires instigate a decadal-scale disruption of forest carbon dynamics. AB - Drought-induced wildfires have increased in frequency and extent over the tropics. Yet, the long-term (greater than 10 years) responses of Amazonian lowland forests to fire disturbance are poorly known. To understand post-fire forest biomass dynamics, and to assess the time required for fire-affected forests to recover to pre-disturbance levels, we combined 16 single with 182 multiple forest census into a unique large-scale and long-term dataset across the Brazilian Amazonia. We quantified biomass, mortality and wood productivity of burned plots along a chronosequence of up to 31 years post-fire and compared to surrounding unburned plots measured simultaneously. Stem mortality and growth were assessed among functional groups. At the plot level, we found that fire affected forests have biomass levels 24.8 +/- 6.9% below the biomass value of unburned control plots after 31 years. This lower biomass state results from the elevated levels of biomass loss through mortality, which is not sufficiently compensated for by wood productivity (incremental growth + recruitment). At the stem level, we found major changes in mortality and growth rates up to 11 years post-fire. The post-fire stem mortality rates exceeded unburned control plots by 680% (i.e. greater than 40 cm diameter at breast height (DBH); 5-8 years since last fire) and 315% (i.e. greater than 0.7 g cm-3 wood density; 0.75-4 years since last fire). Our findings indicate that wildfires in humid tropical forests can significantly reduce forest biomass for decades by enhancing mortality rates of all trees, including large and high wood density trees, which store the largest amount of biomass in old-growth forests. This assessment of stem dynamics, therefore, demonstrates that wildfires slow down or stall the post-fire recovery of Amazonian forests.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297478 TI - Changes in surface hydrology, soil moisture and gross primary production in the Amazon during the 2015/2016 El Nino. AB - The 2015/2016 El Nino event caused severe changes in precipitation across the tropics. This impacted surface hydrology, such as river run-off and soil moisture availability, thereby triggering reductions in gross primary production (GPP). Many biosphere models lack the detailed hydrological component required to accurately quantify anomalies in surface hydrology and GPP during droughts in tropical regions. Here, we take the novel approach of coupling the biosphere model SiBCASA with the advanced hydrological model PCR-GLOBWB to attempt such a quantification across the Amazon basin during the drought in 2015/2016. We calculate 30-40% reduced river discharge in the Amazon starting in October 2015, lagging behind the precipitation anomaly by approximately one month and in good agreement with river gauge observations. Soil moisture shows distinctly asymmetrical spatial anomalies with large reductions across the north-eastern part of the basin, which persisted into the following dry season. This added to drought stress in vegetation, already present owing to vapour pressure deficits at the leaf, resulting in a loss of GPP of 0.95 (0.69 to 1.20) PgC between October 2015 and March 2016 compared with the 2007-2014 average. Only 11% (10 12%) of the reduction in GPP was found in the (wetter) north-western part of the basin, whereas the north-eastern and southern regions were affected more strongly, with 56% (54-56%) and 33% (31-33%) of the total, respectively. Uncertainty on this anomaly mostly reflects the unknown rooting depths of vegetation.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297479 TI - ENSO effects on the transpiration of eastern Amazon trees. AB - Tree transpiration is important in the recycling of precipitation in the Amazon and might be negatively affected by El Nino-Southern Oscillation (ENSO)-induced droughts. To investigate the relative importance of soil moisture deficits versus increasing atmospheric demand (VPD) and determine if these drivers exert different controls over tree transpiration during the wet season versus the dry season (DS), we conducted sap flow measurements in a primary lowland tropical forest in eastern Amazon during the most extreme ENSO-induced drought (2015/2016) recorded in the Amazon. We also assessed whether trees occupying different canopy strata contribute equally to the overall stand transpiration (T stand). Canopy trees were the primary source of T stand However, subcanopy trees are still important as they transpired an amount similar to other biomes around the globe. Tree water use was higher during the DS, indicating that during extreme drought trees did not reduce transpiration in response to low soil moisture. Photosynthetically active radiation and VPD exerted an overriding effect on water use patterns relative to soil moisture during extreme drought, indicating that light and atmospheric constraints play a critical role in controlling ecosystem fluxes of water. Our study highlights the importance of canopy and subcanopy trees to the regional water balance and highlights the resilience to droughts that these trees show during an extreme ENSO event.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'. PMID- 30297480 TI - Interactive effects of tree size, crown exposure and logging on drought-induced mortality. AB - Large trees in the tropics are reportedly more vulnerable to droughts than their smaller neighbours. This pattern is of interest due to what it portends for forest structure, timber production, carbon sequestration and multiple other values given that intensified El Nino Southern Oscillation (ENSO) events are expected to increase the frequency and intensity of droughts in the Amazon region. What remains unclear is what characteristics of large trees render them especially vulnerable to drought-induced mortality and how this vulnerability changes with forest degradation. Using a large-scale, long-term silvicultural experiment in a transitional Amazonian forest in Bolivia, we disentangle the effects of stem diameter, tree height, crown exposure and logging-induced degradation on risks of drought-induced mortality during the 2004/2005 ENSO event. Overall, tree mortality increased in response to drought in both logged and unlogged plots. Tree height was a much stronger predictor of mortality than stem diameter. In unlogged plots, tree height but not crown exposure was positively associated with drought-induced mortality, whereas in logged plots, neither tree height nor crown exposure was associated with drought-induced mortality. Our results suggest that, at the scale of a site, hydraulic factors related to tree height, not air humidity, are a cause of elevated drought-induced mortality of large trees in unlogged plots.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'.

AB - How plants respond physiologically to leaf warming and low water availability may determine how they will perform under future climate change. In 2015-2016, an unprecedented drought occurred across Amazonia with record-breaking high temperatures and low soil moisture, offering a unique opportunity to evaluate the performances of Amazonian trees to a severe climatic event. We quantified the responses of leaf water potential, sap velocity, whole-tree hydraulic conductance (K wt), turgor loss and xylem embolism, during and after the 2015-2016 El Nino for five canopy-tree species. Leaf/xylem safety margins (SMs), sap velocity and K wt showed a sharp drop during warm periods. SMs were negatively correlated with vapour pressure deficit, but had no significant relationship with soil water storage. Based on our calculations of canopy stomatal and xylem resistances, the decrease in sap velocity and K wt was due to a combination of xylem cavitation and stomatal closure. Our results suggest that warm droughts greatly amplify the degree of trees' physiological stress and can lead to mortality. Given the extreme nature of the 2015-2016 El Nino and that temperatures are predicted to increase, this work can serve as a case study of the possible impact climate warming can have on tropical trees.This article is part of a discussion meeting issue 'The impact of the 2015/2016 El Nino on the terrestrial tropical carbon cycle: patterns, mechanisms and implications'.

AB - A 57-year-old woman with a history of asthma, hypertension and substance abuse disorder was admitted to the medical intensive care unit with hypercapnic respiratory failure. After the history was obtained, patient admitted heroin use earlier that day. The initial physical examination revealed right eye ptosis, diplopia, fatigability of neck flexion and extension. She also presented with wheezing and a prolonged expiratory phase. Pupils were 4 mm, with sluggish response to light bilaterally. CT chest with contrast showed a large mediastinal mass. Three different processes coexisted in this patient: simultaneous occurrence of a myasthenia gravis crisis, asthma exacerbation and a component of heroin use. This case highlights a series of overlapping clinical features that could lead to potential confounding and misdiagnosis. Respiratory symptoms improved after initial treatment for asthma exacerbation, but ptosis, diplopia and fatigability of neck muscles persisted. PMID- 30297490 TI - Uncommon manifestation of leptospirosis: a diagnostic challenge. AB - Leptospirosis is a zoonotic disease commonly affecting the tropical countries. It may have protean clinical manifestations including hepatorenal dysfunction, myocarditis, pulmonary haemorrhage, meningitis, optic neuritis and rhabdomyolysis. Neurological manifestation of leptospirosis without the classical hepatorenal dysfunction is a rare entity. This complication of leptospirosis can present with diverse central and peripheral neurological presentations. The overlapping clinical manifestations with many common tropical pathogens often pose diagnostic dilemma and delay in definitive therapy may lead to adverse clinical consequences. We report a case of a 19-year-old man with no prior comorbidities presenting with high-grade fever and altered sensorium. He was diagnosed to be a probable case of leptospirosis, based on all available test results and by fulfilment of parameters under modified Faine's criteria. The patient was successfully managed and discharged in stable condition. PMID- 30297492 TI - Woman with lower back pain, SIADH and a twist of Lyme. AB - A 62-year-old woman was admitted with a 3-week history of atraumatic bilateral lower back pain, progressive ascending flaccid paralysis, hyponatraemia and constipation. She was otherwise in good health with only a recent diagnosis of acute gastroenteritis that preceded her presenting symptoms. Her initial laboratory evaluation was consistent with Syndrome of Inappropriate Antidiuretic Hormone (SIADH) but was otherwise unremarkable. MRI of the spine revealed bilateral diffuse nerve root enhancement from at least C6 to the conus level, suggesting an inflammatory process. Lumbar puncture demonstrated high protein (629 mg/dL) with marked pleocytosis (363 cells/mcL) incompatible with albuminocytological dissociation typically seen in Guillain-Barre syndrome. A thorough diagnostic evaluation was undertaken to explore potential infectious, malignant and autoimmune conditions. Lyme disease serology (ELISA and Western Blot, IgM and IgG) was positive leading to a final diagnosis of lymphocytic meningoradiculitis or Bannwarth syndrome. PMID- 30297491 TI - Solitary vallecular neurofibroma presenting with respiratory obstruction: an unusual presentation. AB - An occurrence of vallecular neurofibroma with airway obstruction is extremely rare and to the best of our knowledge, no case report has been documented in the literature to date. Although microlaryngeal surgery with cold knife excision is the standard surgical procedure offered to patients of vallecular lesions, it can be successfully managed with the help of endoscopic coblation as later can provide a bloodless surgical field preventing the unmet need for the tracheostomy and reducing the postoperative morbidities. PMID- 30297493 TI - Pericardial sarcoma. AB - Pericardial sarcomas are extremely rare aggressive neoplasms. Non-specific symptoms and incidental discovery are usually the rule. Multimodality imaging is extremely important for diagnosis and tissue characterisation of all cardiac masses. Despite treatment, pericardial sarcomas are considered extremely fatal. We encountered a 27-year-old female patient who presented to our facility with progressive dyspnoea. On examination, clinical signs of cardiac tamponade were appreciated, transthoracic echocardiography revealed a tamponading pericardial effusion and a large heterogeneous pericardial mass. Pericardiocentesis revealed haemorrhagic fluid. Subsequently, CT revealed a pericardial mass compressing the right atrium. Excision biopsy showed a well-circumscribed mass, and cut sections showed friable grey-white tissue with areas of haemorrhage and necrosis. Pathological examination confirmed the diagnosis of high-grade undifferentiated sarcoma of the pericardium. The patient was started on adjuvant chemotherapy and radiotherapy. Follow-up after 1 year showed no relapse. PMID- 30297494 TI - Isoniazid-induced pure red cell aplasia. AB - The pure red cell aplasia (PRCA) is an uncommon side effect of isoniazid. We describe a 28-year-old man who developed a severe anaemia caused by PRCA. The patient received antituberculous therapy including isoniazid for his pulmonary tuberculosis. On discontinuation of isoniazid, the anaemia recovered promptly. PRCA should be considered in case of unexplained anaemia during isoniazid treatment. PMID- 30297495 TI - Large mesenteric lymphangioma in an adult patient: an unusual presentation of a rare disease. AB - Lymphangiomas are most commonly described as a small painless mass in the neck or a vesicular rash in an infant patient. Ninety per cent of cases are diagnosed before the age of 2. Treatment usually involves surgical resection. Intra abdominal lymphangiomas and mesenteric lymphangiomas, as described in our case report, represent a rare pathology. The exact prevalence of this condition is unclear but it has been suggested in the literature that there have been as few as 820 cases since the 16th century. The clinical presentation is usually subacute and diagnosis made incidentally during a workup of chronic gastrointestinal symptoms. Acute abdominal symptoms, as in our case presentation, are unusual but may be explained by the mass effect of a large intra-abdominal lesion. Cross-sectional imaging is key in preoperative workup and operative planning. Complete surgical resection is recommended and curative in the majority of cases with a low risk of local recurrence.

PMID- 30297499 TI - Acetaminophen and Febrile Seizure Recurrences During the Same Fever Episode. AB - OBJECTIVES: To confirm the safety of using acetaminophen for febrile seizures (FSs) and to assess its efficacy in preventing FS recurrence during the same fever episode. METHODS: In this single-center, prospective, open, randomized controlled study, we included children and infants (age range: 6-60 months) with FSs who visited our hospital between May 1, 2015, and April 30, 2017. The effectiveness of acetaminophen was examined by comparing the recurrence rates of patients in whom rectal acetaminophen (10 mg/kg) was administered every 6 hours until 24 hours after the first convulsion (if the fever remained >38.0 degrees C) to the rates of patients in whom no antipyretics were administered. No placebo was administered to controls. The primary outcome measure was FS recurrence during the same fever episode. RESULTS: We evaluated 423 patients; of these, 219 were in the rectal acetaminophen group, and 204 were in the no antipyretics group. In the univariate analysis, the FS recurrence rate was significantly lower in the rectal acetaminophen group (9.1%) than in the no antipyretics group (23.5%; P < .001). Among the variables in the final multiple logistic regression analysis, rectal acetaminophen use was the largest contributor to the prevention of FS recurrence during the same fever episode (odds ratio: 5.6; 95% confidence interval: 2.3-13.3). CONCLUSIONS: Acetaminophen is a safe antipyretic against FSs and has the potential to prevent FS recurrence during the same fever episode. PMID- 30297500 TI - Effectiveness of a Hand Hygiene Program at Child Care Centers: A Cluster Randomized Trial. AB - OBJECTIVES: Respiratory infections (RIs) are an important cause of morbidity and excessive antibiotic prescriptions in children attending day care centers (DCCs). We aimed to assess the effectiveness of an educational and hand hygiene program in DCCs and homes in reducing RI incidence and antibiotic prescriptions in children. METHODS: A cluster, randomized, controlled, and open study of 911 children aged 0 to 3 years attending 24 DCCs in Almeria (Spain) with an 8-month follow-up. Two intervention groups of DCC families performed educational and hand hygiene measures, 1 with soap and water (SWG; n = 274), another with hand sanitizer (HSG; n = 339), and the control group (CG; n = 298) followed usual hand washing procedures. RI episode rates were compared through multilevel Poisson regression models. The percentage of days missed were compared with Poisson exact tests. RESULTS: There were 5211 RI episodes registered. Children in the HSG had less risk of RI episodes (incidence rate ratio [IRR]: 0.77; 95% confidence interval [CI]: 0.68-0.88) and antibiotic prescriptions (IRR: 0.69; 95% CI: 0.57 0.84) compared with the those in the CG. Children in the SWG had a higher risk of RI episodes (IRR: 1.21; 95% CI: 1.06-1.39) and antibiotic prescriptions (IRR: 1.31; 95% CI: 1.08-1.56) than those in the HSG. Pupils missed 5186 DCC days because of RIs, and the percentage of days absent was significantly lower in the HSG compared with the CG (P < .001) and the SWG (P < .001). CONCLUSIONS: Hand hygiene programs that include hand sanitizer and educational measures for DCC staff, children, and parents, reduce absent days, RIs, and antibiotic prescriptions for these infections in children at DCCs.

PMID- 30297502 TI - CNS disease-related protein variants as blood-based biomarkers in traumatic brain injury. AB - OBJECTIVE: To utilize a panel of 11 single chain variable fragments (scFvs) that selectively bind disease-related variants of TAR DNA-binding protein (TDP)-43, beta-amyloid, tau, and alpha-synuclein to assess damage following traumatic brain injury (TBI), and determine if the presence of protein variants could account for the increased risk of various neurodegenerative diseases following TBI. METHODS: We utilized the panel of 11 scFvs in a sensitive ELISA format to analyze sera from 43 older veterans, 25 who had experienced at least 1 TBI incident during their lifetime (~29.4 years after TBI), and 18 controls who did not incur TBI, in a cross-sectional study. RESULTS: Each of the 11 scFvs individually could significantly distinguish between TBI and control samples, though they did not detect each TBI sample. Comparing the levels of all 11 variants, all 25 TBI cases displayed higher reactivity compared to the controls and receiver operating characteristic analysis revealed 100% sensitivity and specificity. Higher total protein variants levels correlated with TBI severity and with loss of consciousness. Oligomeric tau levels distinguished between single and multiple TBI incidents. While all TBI cases were readily selected with the panel, the binding pattern varied from patient to patient, suggesting subgroups that are at increased risk for different neurodegenerative diseases. CONCLUSION: The panel of protein variants-specific scFvs can be used to identify blood-based biomarkers indicative of TBI even 20 years or more after the initial TBI. Being able to identify subgroups of biomarker profiles allows for the possibility of individually targeted treatments.

PMID- 30297513 TI - Do apes smell like humans? The role of skin bacteria and volatiles of primates in mosquito host selection. AB - Anthropophilic mosquitoes are effective vectors of human disease because of their biting preferences. To find their host, these mosquitoes are guided by human odours, primarily produced by human skin bacteria. By analysing the skin bacterial and skin volatile profiles of humans, bonobos, chimpanzees, gorillas, lemurs and cows, we investigated whether primates that are more closely related to humans have a skin bacterial community and odour profile that is similar to that of humans. We then investigated whether this affected discrimination between humans and closely related primates by anthropophilic and zoophilic mosquitoes that search for hosts. Humans had a lower skin bacterial diversity than the other animals and their skin bacterial composition was more similar to that in other primates than it was to the skin bacteria of cows. Like the skin bacterial profiles, the volatile profiles of the animal groups were clearly different from each other. The volatile profiles of cows and lemurs were more closely related to the human profiles than expected. Human volatiles were indeed preferred above cow volatiles by anthropophilic mosquitoes and no preference was observed when tested against non-human primate odour, except for bonobo volatiles, which were preferred over human volatiles. Unravelling the differences between mosquito hosts and their effect on host selection is important for a better understanding of cross-species transmission of vector-borne diseases. PMID- 30297514 TI - Endotoxin rapidly desensitizes the gonads to kisspeptin-induced luteinizing hormone release in male Siberian hamsters (Phodopus sungorus). AB - Activation of the immune system induces rapid reductions in hypothalamic pituitary-gonadal (HPG) axis activity, which in turn decreases secretion of sex steroids. This response is likely adaptive for survival by temporarily inhibiting reproduction to conserve energy; however, the physiological mechanisms controlling this response remain unclear. The neuropeptide kisspeptin is a candidate to mediate the decrease in sex hormones seen during sickness through its key regulation of the HPG axis. In this study, the effects of acute immune activation on the response to kisspeptin were assessed in male Siberian hamsters (Phodopus sungorus). Specifically, an immune response was induced in animals by a single treatment of lipopolysaccharide (LPS), and reproductive hormone concentrations were determined in response to subsequent injections of exogenous kisspeptin. Saline-treated controls showed a robust increase in circulating testosterone in response to kisspeptin; however, this response was blocked in LPS treated animals. Circulating luteinizing hormone (LH) levels were elevated in response to kisspeptin in both LPS- and saline-treated groups and, thus, were unaffected by LPS treatment, suggesting gonad-level inhibition of testosterone release despite central HPG activation. In addition, blockade of glucocorticoid receptors by mifepristone did not attenuate the LPS-induced inhibition of testosterone release, suggesting that circulating glucocorticoids do not mediate this phenomenon. Collectively, these findings reveal that acute endotoxin exposure rapidly renders the gonads less sensitive to HPG stimulation, thus effectively inhibiting sex hormone release. More broadly, these results shed light on the effects of immune activation on the HPG axis and help elucidate the mechanisms controlling energy allocation and reproduction. PMID- 30297515 TI - Relationship between circulating inflammation proteins and lung cancer diagnosis in the National Lung Screening Trial. AB - BACKGROUND: Previously, we observed a strong relationship between circulating serum inflammation proteins in relation to lung cancer diagnosis and risk, both in case-control and prospective cohorts. Low dose CT (LDCT) screening has a high prevalence of false positive nodules, thus companion non-invasive biomarkers that can distinguish between benign and malignant nodules could have clinical utility and positive impact on patient outcomes. METHODS: We conducted a nested case control study within the National Lung Screening Trial (NLST). Concentrations of 30 inflammation proteins were measured on plasma samples of 262 cases and 528 controls using a highly sensitive and analytically validated electrochemiluminescence V-PLEX immunoassay. RESULTS: Comparing the 4th quartile with 1st quartile, we found increased IFN-gamma and IL-12/IL-23p40 associated with increased odds of a lung cancer diagnosis (OR 1.89, 95% C.I. 1.16-3.09; OR 2.49, 95% C.I. 1.46-4.23, respectively). Confirming our previous observations, we also detected a relationship between increased IL-6, IL-8 and CRP with lung cancer diagnosis. These relationships were significant after adjustment for age, gender, race, smoking, BMI, family history of lung cancer and previous diagnoses of inflammatory conditions. However, none of these proteins could distinguish between a benign and malignant lung nodule (IL-6: OR 1.25, 95% C.I. 0.59-2.64; IL 8: OR 1.40, 95% C.I. 0.70-2.81; CRP: OR 0.98, 95% C.I. 0.45-2.12). CONCLUSIONS: We have discovered new associations for IFN-gamma and IL-12/IL-23p40 with lung cancer but have no evidence that these proteins can distinguish between benign and malignant lung nodules. IMPACT: Circulating inflammation proteins are unlikely to have utility as companion LDCT biomarkers. PMID- 30297516 TI - Exposure to trace elements and risk of skin cancer: A systematic review of epidemiologic studies. AB - Exposure to environmental trace elements has been studied in relation to many cancers. However, an association between exposure to trace elements and skin cancer remains less understood. Therefore, we conducted a systematic review of published epidemiologic literature examining the association between exposure to trace elements, and risk of melanoma and keratinocyte carcinoma in humans. We identified epidemiologic studies investigating exposure to arsenic, cadmium, chromium, copper, iron, selenium, and zinc and risk of skin cancer in humans. Among the minerals, arsenic, selenium, and zinc had more than 5 studies available. Exposure to arsenic was associated with increased risk of keratinocyte carcinoma, while too few studies existed on melanoma to draw conclusions. Exposure to selenium was associated with possible increased risk of keratinocyte carcinoma. Studies of zinc and skin cancer were case-control in design and were found to have inconsistent associations. The data on the association between cadmium, chromium, copper, and iron and risk of skin cancer remain too sparse to draw any conclusions. In summary, epidemiologic studies on exposure to trace elements and cutaneous malignancies are limited. Studies with larger sample sizes and prospective designs are warranted to improve our knowledge of trace elements and skin cancer.

PMID- 30297518 TI - Elevated YKL-40 and low sAPPbeta:YKL-40 ratio in antemortem cerebrospinal fluid of patients with pathologically confirmed FTLD. AB - OBJECTIVES: The combination of high YKL-40 (a glial inflammatory marker) and low sAPPbeta (a soluble beta fragment of amyloid precursor protein) in cerebrospinal fluid (CSF) has been associated with frontotemporal lobar degeneration (FTLD) in clinical series. We investigate these biomarkers in a neuropathologically confirmed cohort of patients with FTLD. METHODS: CSF samples were selected from the Penn FTD Center (University of Pennsylvania). Participants were followed to autopsy and had a neuropathological diagnosis of FTLD-Tau (n=24), transactive response DNA-binding protein with 43 kDa (FTLD-TDP) (n=25) or Alzheimer's disease (AD, n=97). We compared levels of YKL-40 and sAPPbeta between groups and with cognitively normal controls (n=77), and assessed their diagnostic utility using receiver operating characteristic curves. We also investigated the effect of AD copathology and the correlation between these CSF markers and tau burden at autopsy. RESULTS: Both FTLD groups had lower levels of sAPPbeta, higher levels of YKL-40 and lower sAPPbeta:YKL-40 ratio in CSF compared with controls. The group of pure FTLD-Tau (without AD copathology) showed higher levels of YKL-40 than AD and than pure FTLD-TDP. YKL-40 levels correlated with pathological tau burden. The sAPPbeta:YKL-40 ratio had an area under the curve (AUC) of 0.91 (95% CI 0.86 to 0.96) to distinguish subjects with FTLD from controls, but lower values to distinguish FTLD from AD (AUC 0.70; 95% CI 0.61 to 0.79) and to discriminate FTLD-Tau from FTLD-TDP (AUC 0.67; 95% CI 0.51 to 0.82). CONCLUSIONS: Our study provides pathological confirmation that the combination of low sAPPbeta and high YKL-40 in CSF is associated with FTLD. These biomarkers could be useful in particular clinical settings when FTLD is suspected. PMID- 30297519 TI - Cognitive decline in Parkinson's disease: the impact of the motor phenotype on cognition. AB - OBJECTIVES: Parkinson's disease (PD) is the second most common neurodegenerative disorder and is further associated with progressive cognitive decline. In respect to motor phenotype, there is some evidence that akinetic-rigid PD is associated with a faster rate of cognitive decline in general and a greater risk of developing dementia.The objective of this study was to examine cognitive profiles among patients with PD by motor phenotypes and its relation to cognitive function. METHODS: Demographic, clinical and neuropsychological cross-sectional baseline data of the DEMPARK/LANDSCAPE study, a multicentre longitudinal cohort study of 538 patients with PD were analysed, stratified by motor phenotype and cognitive syndrome. Analyses were performed for all patients and for each diagnostic group separately, controlling for age, gender, education and disease duration. RESULTS: Compared with the tremor-dominant phenotype, akinetic-rigid patients performed worse in executive functions such as working memory (Wechsler Memory Scale-Revised backward; p=0.012), formal-lexical word fluency (p=0.043), card sorting (p=0.006), attention (Trail Making Test version A; p=0.024) and visuospatial abilities (Leistungsprufungssystem test 9; p=0.006). Akinetic-rigid neuropsychological test scores for the executive and attentive domain correlated negatively with non-tremor motor scores. Covariate-adjusted binary logistic regression analyses showed significant odds for PD-mild cognitive impairment for not-determined as compared with tremor-dominant (OR=3.198) and akinetic-rigid PD (OR=2.059). The odds for PD-dementia were significant for akinetic-rigid as compared with tremor-dominant phenotype (OR=8.314). CONCLUSION: The three motor phenotypes of PD differ in cognitive performance, showing that cognitive deficits seem to be less severe in tremor-dominant PD. While these data are cross sectional, longitudinal data are needed to shed more light on these differential findings. PMID- 30297521 TI - The reunification of amyotrophic lateral sclerosis. PMID- 30297522 TI - Atypical chronic inflammatory demyelinating polyneuropathies. PMID- 30297520 TI - Atypical CIDP: diagnostic criteria, progression and treatment response. Data from the Italian CIDP Database. AB - OBJECTIVES: A few variants of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) have been described, but their frequency and evolution to typical CIDP remain unclear. To determine the frequency and characteristics of the CIDP variants, their possible evolution to typical CIDP, and treatment response. METHODS: We applied a set of diagnostic criteria to 460 patients included in a database of Italian patients with CIDP. Clinical characteristics and treatment response were reviewed for each patient. The Kaplan Meier curve was used to estimate the progression rate from atypical to typical CIDP. RESULTS: At the time of inclusion, 376 (82%) patients had a diagnosis of typical CIDP while 84 (18%) had atypical CIDP, including 34 (7%) with distal acquired demyelinating symmetric neuropathy (DADS), 17 (4%) with purely motor, 17 (4%) with Lewis-Sumner syndrome (LSS) and 16 (3.5%) with purely sensory CIDP. Based on retrospective review of the symptoms and signs present at onset and for at least 1 year, 180 (39%) patients had an initial diagnosis compatible with atypical CIDP that in 96 (53%) patients evolved to typical CIDP. Mean disease duration was longer in patients evolving to typical CIDP than in those not evolving (p=0.0016). Patients with DADS and LSS had a less frequent response to immunoglobulin than those with typical CIDP, while patients with purely motor and sensory CIDP had a similar treatment response. CONCLUSIONS: The proportion of patients with atypical CIDP varies during the disease course. DADS and LSS have a less frequent response to intravenous immunoglobulin compared with typical CIDP, raising the possibility of a different underlying pathogenetic mechanism. PMID- 30297523 TI - Tamm-Horsfall protein protects the urinary tract against Candida albicans. AB - Urinary tract infections (UTIs) caused by the human fungal pathogen Candida albicans and related species are prevalent in hospitalized patients, especially those on antibiotic therapy, with indwelling catheters, or with predisposing conditions such as diabetes or immunodeficiency. Understanding of key host defenses against Candida UTI are critical for developing effective treatment strategies. Tamm-Horsfall glycoprotein (THP) is the most abundant urine protein with multiple roles in renal physiology and bladder protection. THP protects against bacterial UTI by blocking bacterial adherence to the bladder epithelium, but its role in defense against fungal pathogens is not yet described. Here, we demonstrate that THP restricts colonization of the urinary tract by C. albicans THP binds to C. albicans hyphae, but not the yeast form, in a manner dependent on fungal expression of the Als3 adhesion glycoprotein. THP directly blocks C. albicans adherence to bladder epithelial cells in vitro and THP-deficient mice display increased fungal burden in a C. albicans UTI model. This work outlines a previously unknown role for THP as an essential component for host immune defense against fungal urinary tract infection. PMID- 30297525 TI - A non-fimbrial adhesin of Aggregatibacter actinomycetemcomitans mediates biofilm biogenesis. AB - Periodontitis is an inflammatory disease caused by polymicrobial biofilms. The periodontal pathogen Aggregatibacter actinomycetemcomitans displays two proteinaceous surface structures, the fimbriae and the non-fimbrial extracellular matrix binding protein A (EmaA), as observed by electron microscopy. Fimbriae participate in biofilm biogenesis and the EmaA adhesins mediate collagen binding. However, in the absence of fimbriae, A. actinomycetemcomitans still retains the potential to form robust biofilms, suggesting other surface macromolecules participate in biofilm development. Here, isogenic mutant strains lacking EmaA structures, but still expressing fimbriae, were observed to have reduced biofilm potential. In strains lacking both EmaA and fimbriae, biofilm mass was reduced by 80%. EmaA enhanced biofilm formation in different strains, independent of the fimbriation state or serotype. Confocal microscopy revealed differences in cell density within microcolonies between the EmaA positive and mutant strains. EmaA mediated biofilm formation was found to be independent of the glycosylation state and the precise 3-D conformation of the protein, and thus this function is uncorrelated with collagen binding activity. The data suggests that EmaA is a multifunctional adhesin that utilizes different mechanisms to enhance bacterial binding to collagen and to enhance biofilm formation, both of which are important for A. actinomycetemcomitans colonization and subsequent infection. PMID- 30297524 TI - NanI Sialidase Is an Important Contributor to Clostridium perfringens Type F Strain F4969 Intestinal Colonization in Mice. AB - Clostridium perfringens type F (formerly enterotoxigenic C. perfringens type A) strains produce an enterotoxin (CPE) to cause acute cases of food poisoning and chronic nonfoodborne human gastrointestinal diseases (NFD), e.g., antibiotic associated diarrhea (AAD). NFD strains also produce NanI sialidase, an extracellular enzyme that releases sialic acids from sialyated host macromolecules. Recent in vitro studies suggested that NanI may contribute to NFD strain intestinal colonization by enhancing the adherence of such strains to intestinal cells and promoting their bacterial growth using generated sialic acid as an energy source. The current study tested this hypothesis by developing a mouse intestinal colonization model involving clindamycin pretreatment to produce conditions mimicking those during AAD. In this model, the type F NFD strain F4969 persisted for at least 4 days in the small intestine, cecum, and colon. When clindamycin-pretreated mice were challenged by oral gavage with equivalent numbers of F4969 bacteria or its isogenic nanI null mutant, significantly lower numbers of the nanI mutant were recovered from all intestinal segments, and it was completely cleared from the small intestine by day 4. Complementation of the mutant to restore NanI production also promoted colonization. When the same nanI null mutant strain was coinoculated into the mouse model together with a nanI producing strain, the numbers of this mutant were restored to wild-type F4969 levels in all intestinal segments. This result suggests that sialidases produced by other bacteria might also provide some support for C. perfringens intestinal colonization. Collectively, these in vivo findings identify NanI to be the first known significant contributor to chronic intestinal colonization by NFD strains. PMID- 30297526 TI - Atg5 Supports R. australis Infection in Macrophages in vitro and in vivo. AB - Rickettsiae can cause life-threatening infections in humans. Macrophages are one of the initial targets for rickettsiae after inoculation by ticks. However, it remains poorly understood how rickettsiae remain free in macrophages prior to establishing their infection in microvascular endothelial cells. Here, we demonstrated that the concentration of Rickettsia australis was significantly greater in infected tissues of Atg5flox/flox mice compared to the counterparts of Atg5flox/flox Lyz-Cre mice, in association with a reduced level of IL-1beta in serum. The greater concentration of R. australis in Atg5 flox/flox bone marrow derived macrophages (BMMs) compared to Atg5 flox/flox Lyz-Cre BMMs in vitro was abolished by exogenous treatment with recombinant IL-1beta. Rickettsia australis induced significantly increased levels of LC3-II and LC3 puncta in Atg5-competent BMMs, but not in Atg5- deficient BMMs, while no p62 turnover was observed. Further analysis found that the co-localization of LC3 with a small portion of R. australis and Rickettsia-containing double-membrane-bound vacuoles in BMMs of B6 mice. Moreover, treatment with rapamycin significantly increased the concentrations of R. australis in B6 BMMs compared to the untreated controls. Taken together, our results demonstrated that Atg5 favors R. australis infection in mouse macrophages in association with a suppressed production level of IL 1beta but not active autophagy flux. These data highlight the contribution of Atg5 in macrophages to the pathogenesis of rickettsial diseases. PMID- 30297527 TI - Acinetobacter baumannii OxyR regulates the transcriptional response to hydrogen peroxide. AB - Acinetobacter baumannii is a Gram-negative opportunistic pathogen that causes diverse infections, including pneumonia, bacteremia, and wound infections. Due to multiple intrinsic and acquired antimicrobial-resistance mechanisms, A. baumannii isolates are commonly multi-drug resistant and infections are notoriously difficult to treat. The World Health Organization recently highlighted carbapenem resistant A. baumannii as a 'critical priority' for the development of new antimicrobials because of the risk to human health posed by this organism. Therefore, it is important to discover mechanisms used by A. baumannii to survive stresses encountered during infection in order to identify new drug targets. In this study, we identified hydrogen peroxide (H2O2) as a stressor produced in the lung during A. baumannii infection using in vivo imaging and defined OxyR as a transcriptional regulator of the H2O2 stress response. Upon exposure to H2O2, A. baumannii differentially transcribes several hundred genes. However, transcriptional upregulation of genes predicted to detoxify hydrogen peroxide is abolished in A. baumannii genetically inactivated for the transcriptional regulator oxyR. Moreover, inactivation of oxyR in both antimicrobial-susceptible and multi-drug-resistant A. baumannii strains impairs growth in the presence of H2O2 OxyR is a direct regulator of katE and ahpF1, which encode the major H2O2 degrading enzymes in A. baumannii, as confirmed through measurement of promoter binding by recombinant OxyR in electromobility shift assays. Finally, an oxyR mutant is less fit than wild-type A. baumannii during infection of the murine lung. This work reveals a mechanism used by this important human pathogen to survive H2O2 stress encountered during infection. PMID- 30297528 TI - How to improve the assessment of the impact of occupational diseases at a national level? The Netherlands as an example. AB - OBJECTIVE: To explore the impact of occupational diseases (ODs) through estimations of population attributable fractions (PAFs) in a national context. METHODS: PAFs were calculated for eight prevalent ODs using existing data on the prevalence of exposure to risk factors at work and the strength of their association with diseases based on systematic reviews. Six systematic reviews with meta-analyses and two overview papers were selected. All addressed the relationship between occupational exposure to work-related risk factors for these eight prevalent ODs. Prevalence figures for exposure to work-related risk factors were retrieved from the Dutch National Working Conditions Survey (NWCS) based on self-reports by approximately 40 000 workers. The specific risk factors retrieved from the reviews were matched with the available and dichotomised self-reported exposure items from the NWCS by two authors. RESULTS: The eight frequently reported ODs among the Dutch working population revealed PAFs varying between 3% and 25%. Lateral epicondylitis and distress/burnout had the highest attributable fractions, with percentages of 25% and 18%, respectively. For knee osteoarthritis (13%), shoulder soft tissue disorders (10%) and non-specific low back pain (10%) approximately 1 in 10 cases were attributable to work. PAFs for irritant contact dermatitis, noise-induced hearing loss and chronic obstructive pulmonary disease were 15%, 6% and 3%, respectively. CONCLUSION: Data from systematic reviews and self-reported data on exposure provide opportunities to estimate the impact of ODs. For the Netherlands, they revealed substantial and varying attributions of work for prevalent diseases. PMID- 30297529 TI - Tuberculosis, mining and silica. PMID- 30297531 TI - Intratumoral Immunotherapy with XCL1 and sFlt3L Encoded in Recombinant Semliki Forest Virus-Derived Vectors Fosters Dendritic Cell-Mediated T-cell Cross Priming. AB - : Multiple lines of evidence indicate a critical role of antigen cross presentation by conventional BATF3-dependent type 1 classical dendritic cells (cDC1) in CD8-mediated antitumor immunity. Flt3L and XCL1, respectively, constitute a key growth/differentiation factor and a potent and specific chemoattractant for cDC1. To exploit their antitumor functions in local immunotherapy, we prepared Semliki Forest Virus (SFV)-based vectors encoding XCL1 and soluble Flt3L (sFlt3L). These vectors readily conferred transgene expression to the tumor cells in culture and when engrafted as subcutaneous mouse tumor models. In syngeneic mice, intratumoral injection of SFV-XCL1-sFlt3L (SFV-XF) delayed progression of MC38- and B16-derived tumors. Therapeutic activity was observed and exerted additive effects in combination with anti-PD-1, anti-CD137, or CTLA-4 immunostimulatory mAbs. Therapeutic effects were abolished by CD8beta T cell depletion and were enhanced by CD4 T-cell depletion, but not by T regulatory cell predepletion with anti-CD25 mAb. Antitumor effects were also abolished in BATF3- and IFNAR-deficient mice. In B16-OVA tumors, SFV-XF increased the number of infiltrating CD8 T cells, including those recognizing OVA. Consistently, following the intratumoral SFV-XF treatment courses, we observed increased BATF3 dependent cDC1 among B16-OVA tumor-infiltrating leukocytes. Such an intratumoral increase was not seen in MC38-derived tumors, but both resident and migratory cDC1 were boosted in SFV-XF-treated MC38 tumor-draining lymph nodes. In conclusion, viral gene transfer of sFlt3L and XCL1 is feasible, safe, and biologically active in mice, exerting antitumor effects that can be potentiated by CD4 T-cell depletion. SIGNIFICANCE: These findings demonstrate that transgenic expression of sFLT3L and XCL1 in tumor cells mediates cross-priming of, and elicits potent antitumor activity from, CD8 T lymphocytes, particularly in combination with CD4 T-cell depletion. PMID- 30297532 TI - DNA Polymerase Eta Prevents Tumor Cell-Cycle Arrest and Cell Death during Recovery from Replication Stress. AB - : Neoplastic transformation and genome instability are enhanced by replication stress, conditions that slow or stall DNA replication forks. Consequently, cancer cells require multiple enzymes and checkpoint signaling pathways to mitigate replication stress for their viability and proliferation. Targeting proteins that enhance cancer cell survival during replication stress is a recent approach in clinical strategies, especially when targets produce synthetic lethality. DNA polymerase eta (Pol eta) has many key functions in genome stability, particularly for translesion synthesis. Here we demonstrate that endogenous Pol eta displays significant protein induction and forms intense foci throughout the nucleus in response to replication stress induced by drugs that do not directly form DNA adducts. During replication stress, Pol eta-deficient cells displayed hyperactivation of the ATR replication checkpoint and arrested late in the cell cycle. During recovery from replication stress, Pol eta-deficient cells continue to display aberrant phenotypes, including delayed cell-cycle progression, apoptosis, and cell survival. Depletion or inhibition of ATR was synthetically lethal with Pol eta deficiency, particularly when tumor cells were treated with replication stress-inducing drugs. Together our data expand knowledge of the cellular environments that increase endogenous Pol eta expression beyond DNA damaging agents and demonstrate that Pol eta regulation is central to the replication stress response. Because Pol eta is aberrantly expressed in several tumor types, our results are critical for developing more effective chemotherapy approaches and identify coinhibition of Pol eta and ATR as a potential therapeutic strategy. SIGNIFICANCE: This study demonstrates that replication stress upregulates Pol eta (POLH) in tumor cells and reveals a role for Pol eta in tumor cell recovery following replication stress. PMID- 30297530 TI - Distinct roles of VE-cadherin for development and maintenance of specific lymph vessel beds. AB - Endothelial cells line blood and lymphatic vessels and form intercellular junctions, which preserve vessel structure and integrity. The vascular endothelial cadherin, VE-cadherin, mediates endothelial adhesion and is indispensible for blood vessel development and permeability regulation. However, its requirement for lymphatic vessels has not been addressed. During development, VE-cadherin deletion in lymphatic endothelial cells resulted in abortive lymphangiogenesis, edema, and prenatal death. Unexpectedly, inducible postnatal or adult deletion elicited vessel bed-specific responses. Mature dermal lymph vessels resisted VE-cadherin loss and maintained button junctions, which was associated with an upregulation of junctional molecules. Very different, mesenteric lymphatic collectors deteriorated and formed a strongly hyperplastic layer of lymphatic endothelial cells on the mesothelium. This massive hyperproliferation may have been favored by high mesenteric VEGF-C expression and was associated with VEGFR-3 phosphorylation and upregulation of the transcriptional activator TAZ Finally, intestinal lacteals fragmented into cysts or became highly distended possibly as a consequence of the mesenteric defects. Taken together, we demonstrate here the importance of VE-cadherin for lymphatic vessel development and maintenance, which is however remarkably vessel bed specific. PMID- 30297533 TI - Targeting PARP1 in XRCC1 deficient sporadic invasive breast cancer or pre invasive ductal carcinoma in situ induces synthetic lethality and chemoprevention. AB - Targeting PARP1 for synthetic lethality is a new strategy for breast cancers harboring germline mutations in BRCA. However, these mutations are rare, and reactivation of BRCA-mediated pathways may result in eventual resistance to PARP1 inhibitor therapy. Alternative synthetic lethality approaches targeting more common sporadic breast cancers and pre-invasive ductal carcinoma in situ (DCIS) are desirable. Here we show that downregulation of XRCC1, which interacts with PARP1 and coordinates base excision repair, is an early event in human breast cancer pathogenesis. XRCC1-deficient DCIS were aggressive and associated with increased risk of local recurrence. Human invasive breast cancers deficient in XRCC1 and expressing high PARP1 levels also manifested aggressive features and poor outcome. The PARP1 inhibitor Olaparib was synthetically lethal in XRCC1 deficient DCIS and invasive breast cancer cells. We conclude that targeting PARP1 is an attractive strategy for synthetic lethality and chemoprevention in XRCC1 deficient breast cancers, including pre-invasive DCIS. PMID- 30297534 TI - Pathologic Oxidation of PTPN12 Underlies ABL1 Phosphorylation in Hereditary Leiomyomatosis and Renal Cell Carcinoma. AB - : Hereditary leiomyomatosis and renal cell carcinoma (HLRCC) is an inherited cancer syndrome associated with a highly aggressive form of type 2 papillary renal cell carcinoma (PRCC). Germline inactivating alterations in fumarate hydratase (FH) cause HLRCC and result in elevated levels of reactive oxygen species (ROS). Recent work indicates that FH-/- PRCC cells have increased activation of ABL1, which promotes tumor growth, but how ABL1 is activated remains unclear. Given that oxidation can regulate protein-tyrosine phosphatase (PTP) catalytic activity, inactivation of an ABL-directed PTP by ROS might account for ABL1 activation in this malignancy. Our group previously developed "q oxPTPome," a method that globally monitors the oxidation of classical PTPs. In this study, we present a refined q-oxPTPome, increasing its sensitivity by >10*. Applying q-oxPTPome to FH-deficient cell models showed that multiple PTPs were either highly oxidized (including PTPN12) or overexpressed. Highly oxidized PTPs were those with relatively high sensitivity to exogenous H2O2. Most PTP oxidation in FH-deficient cells was reversible, although nearly 40% of PTPN13 was irreversibly oxidized to the sulfonic acid state. Using substrate-trapping mutants, we mapped PTPs to their putative substrates and found that only PTPN12 could target ABL1. Furthermore, knockdown experiments identified PTPN12 as the major ABL1 phosphatase, and overexpression of PTPN12 inhibited ABL1 phosphorylation and HLRCC cell growth. These results show that ROS-induced oxidation of PTPN12 accounts for ABL1 phosphorylation in HLRCC-associated PRCC, revealing a novel mechanism for inactivating a tumor suppressor gene product and establishing a direct link between pathologic PTP oxidation and neoplastic disease. SIGNIFICANCE: This work identifies a novel mechanism of activation of the oncogenic kinase ABL1 via ROS-induced, oxidation-mediated inactivation of cognate protein tyrosine phosphatases. PMID- 30297535 TI - Pharmacological Inhibition of PARP6 Triggers Multipolar Spindle Formation and Elicits Therapeutic Effects in Breast Cancer. AB - : PARP proteins represent a class of post-translational modification enzymes with diverse cellular functions. Targeting PARPs has proven to be efficacious clinically, but exploration of the therapeutic potential of PARP inhibition has been limited to targeting poly(ADP-ribose) generating PARP, including PARP1/2/3 and tankyrases. The cancer-related functions of mono(ADP-ribose) generating PARP, including PARP6, remain largely uncharacterized. Here, we report a novel therapeutic strategy targeting PARP6 using the first reported PARP6 inhibitors. By screening a collection of PARP compounds for their ability to induce mitotic defects, we uncovered a robust correlation between PARP6 inhibition and induction of multipolar spindle (MPS) formation, which was phenocopied by PARP6 knockdown. Treatment with AZ0108, a PARP6 inhibitor with a favorable pharmacokinetic profile, potently induced the MPS phenotype, leading to apoptosis in a subset of breast cancer cells in vitro and antitumor effects in vivo. In addition, Chk1 was identified as a specific substrate of PARP6 and was further confirmed by enzymatic assays and by mass spectrometry. Furthermore, when modification of Chk1 was inhibited with AZ0108 in breast cancer cells, we observed marked upregulation of p-S345 Chk1 accompanied by defects in mitotic signaling. Together, these results establish proof-of-concept antitumor efficacy through PARP6 inhibition and highlight a novel function of PARP6 in maintaining centrosome integrity via direct ADP-ribosylation of Chk1 and modulation of its activity. SIGNIFICANCE: These findings describe a new inhibitor of PARP6 and identify a novel function of PARP6 in regulating activation of Chk1 in breast cancer cells. PMID- 30297536 TI - CDK1 Interacts with Sox2 and Promotes Tumor Initiation in Human Melanoma. AB - : Cancers are composed of heterogeneous subpopulations with various tumor initiating capacities, yet key stem cell genes associated with enhanced tumor initiating capacities and their regulatory mechanisms remain elusive. Here, we analyzed patient-derived xenografts from melanoma, colon, and pancreatic cancer tissues and identified enrichment of tumor-initiating cells in MHC class I-hi cells, where CDK1, a master regulator of the cell cycle, was upregulated. Overexpression of CDK1, but not its kinase-dead variant, in melanoma cells increased their spheroid forming ability, tumorigenic potential, and tumor initiating capacity; inhibition of CDK1 with pharmacologic agents reduced these characteristics, which was unexplained by the role of CDK1 in regulating the cell cycle. Proteomic analysis revealed an interaction between CDK1 and the pluripotent stem cell transcription factor Sox2. Blockade or knockdown of CDK1 resulted in reduced phosphorylation, nuclear localization, and transcriptional activity of Sox2. Knockout of Sox2 in CDK1-overexpressing cells reduced CDK1 driven tumor-initiating capacity substantially. Furthermore, GSEA analysis of CDK1hi tumor cells identified a pathway signature common in all three cancer types, including E2F, G2M, MYC, and spermatogenesis, confirming a stem-like nature of CDK1hi tumor cells. These findings reveal a previously unrecognized role for CDK1 in regulating tumor-initiating capacity in melanoma and suggest a novel treatment strategy in cancer via interruption of CDK1 function and its protein-protein interactions. SIGNIFICANCE: These findings uncover CDK1 as a new regulator of Sox2 during tumor initiation and implicate the CDK1-Sox2 interaction as a potential therapeutic target in cancer. PMID- 30297537 TI - Hemorrhagic transformation is associated with poor functional outcome in patients with acute ischemic stroke due to a large vessel occlusion. AB - BACKGROUND AND PURPOSE: Hemorrhagic transformation (HT) is a complication that may cause neurological deterioration in patients with acute ischemic stroke. Various radiological subtypes of HT can be distinguished. Their influence on functional outcome is currently unclear. The purpose of this study was to assess the associations between HT subtypes and functional outcome in acute ischemic stroke patients with proven large vessel occlusion included in the MR CLEAN trial (Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic stroke in The Netherlands). METHODS: All patients with follow-up imaging were included. HT was classified on follow-up CT scans according to the European Cooperative Acute Stroke Study II classification. Functional outcome was assessed using the modified Rankin Scale (mRS) 90 days after stroke onset. Ordinal logistic regression analysis with adjustment for potential confounders was used to determine the association of HT subtypes with functional outcome. RESULTS: Of 478 patients, 222 had HT. Of these, 76 (16%) patients were classified as hemorrhagic infarction type 1, 71 (15%) as hemorrhagic infarction type 2, 36 (8%) as parenchymal hematoma type 1, and 39 (8%) as parenchymal hematoma type 2. Hemorrhagic infarction type 2 (adjusted common OR (acOR) 0.54, 95% CI: 0.32 to 0.89) and parenchymal hematoma type 2 (acOR 0.37, 95% CI 0.17 to 0.78) were significantly associated with a worse functional outcome. Hemorrhagic infarction type 1 and parenchymal hematoma type 1 were not significantly associated, although their point estimates pointed in the direction of worse outcome. CONCLUSION: This study suggests that parenchymal hematoma type 2 is relevant for functional outcome after an acute ischemic stroke, and smaller HTs might also influence long term functional outcome. TRAIL REGISTRATION NUMBER: ISRCTN10888758. PMID- 30297538 TI - Revisiting the therapeutic time window dogma: successful thrombectomy 6 days after stroke onset. AB - Stroke is the leading cause of serious long-term disability in the USA. Recent clinical trials, DAWN and DEFUSE 3, have expanded the endovascular therapeutic time window which has been adopted by the American Heart Association stroke guideline. However, there continues to be a dilemma as to what is the best approach for patients who present beyond the time window set by these trials and the current guideline. The interval from arterial occlusion to completion of brain tissue infarction varies from patient to patient and depends on the actual time and also a physiological clock or a tissue time window. Offering endovascular treatment based solely on a rigid time criterion excludes patients who may have a clinical benefit because of potentially salvageable tissue. We present a case of a patient who underwent successful stroke thrombectomy 6 days after stroke onset. PMID- 30297539 TI - SAFE study (Safety and efficacy Analysis of FRED Embolic device in aneurysm treatment): 1-year clinical and anatomical results. AB - BACKGROUND AND PURPOSE: Flow diversion is an innovative and increasingly used endovascular treatment for intracranial aneurysms. Its initial evaluation with the first devices available showed good efficacy of this treatment with variable safety results. The Flow Direction Endoluminal Device (FRED) has a specific design and was evaluated in a single-arm, multicenter, prospective, Good Clinical Practice study: SAFE (Safety and efficacy Analysis of FRED Embolic device in aneurysm treatment). This analysis reports clinical results at 1 year and anatomical results at 6 months and 1 year. METHODS: Patients with unruptured and recanalized aneurysms located in the anterior circulation treated with FRED and FRED Jr were prospectively included. A Clinical Event Committee and a Core Laboratory independently evaluated clinical outcome and anatomical results. RESULTS: Thirteen interventional neuroradiology centers included 103 patients/aneurysms. Aneurysm locations were supraclinoid internal carotid artery (ICA) in 71 (68.9%), cavernous ICA in 15 (14.6%), anterior cerebral or anterior communicating artery in 9 (8.7%), and middle cerebral artery in 8 (7.8%). Most aneurysms were small (<10 mm) in 71 patients (68.9%). Cumulative 1-year mortality and morbidity rates were 2/103 (1.9%) and 3/103 (2.9%), respectively, one death being related to cancer. At 1 year, anatomical results were: complete occlusion in 66/90 patients (73.3%), neck remnant in 7/90 patients (7.8%), and aneurysm remnant in 17/90 patients (18.9%). CONCLUSIONS: SAFE study analysis at 1 year confirms the excellent safety profile of the FRED device for aneurysm treatment, with low morbidity and mortality rates (2.9% and 1.9%, respectively) and demonstrates its efficacy (adequate occlusion in 73/90 (81.1%)).

AB - BACKGROUND: Extensive lytic lesions of the vertebral body (VB) increase risk of fracture and instability and require stabilization of the anterior column. Vertebral augmentation is an accepted treatment option, but when osteolysis has extensively destroyed the VB cortical boundaries (a condition herein defined as 'extreme osteolysis'), the risk of cement leakage and/or insufficient filling is high. Vertebral body stents (VBSs) might allow partial restoration of VB height, cement containment, and reinforcement, but their use in extreme osteolysis has not been investigated. OBJECTIVE: To assess retrospectively the feasibility and safety of VBS augmentation in patients with 'extreme osteolysis' of the VB. METHODS: We retrospectively analyzed 41 treated vertebrae (from T1 to L5). VB reconstruction was assessed on postprocedure CT images and rated on a qualitative 4-point scale (poor-fair-good-excellent). Clinical and radiological follow-up was performed at 1 month and thereafter at intervals in accordance with oncological protocols. RESULTS: VBS augmentation was performed at 12 lumbar and 29 thoracic levels, with bilateral VBS in 23/41. VB reconstruction was judged satisfactory (good or excellent) in 37/41 (90%) of levels. Bilateral VBS received higher scores than unilateral (p=0.057, Pearson's X2). We observed no periprocedural complications. Cement leaks (epidural or foraminal) occurred at 5/41 levels (12.2%) without clinical consequences. Follow-up data were available for 27/29 patients, extending beyond 6 months for 20 patients (7-28 months, mean 15.3 months). VBS implant stability was observed in 40/41 cases (97.5%). CONCLUSIONS: Our results support the use of VBS as a minimally invasive, safe and effective option for reconstructing the anterior column in prominent VB osteolysis. PMID- 30297541 TI - Mothership versus drip and ship for thrombectomy in patients who had an acute stroke: a systematic review and meta-analysis. AB - BACKGROUND: The effectiveness of mechanical thrombectomy (MT) in acute ischemic stroke due to large vessel occlusion is time-dependent. While only stroke centers with endovascular capabilities perform MT, many patients who had a stroke initially present to the closest primary stroke centers capable of administering earlier intravenous thrombolysis, and then require to be transferred to a comprehensive stroke center for MT. PURPOSE: To compare the outcomes of this care pathway (drip and ship (DS)) with that whereby patients are directly transferred to a comprehensive stroke center (mothership (MS)). METHODS: We performed a systematic review and meta-analysis of published studies using several electronic databases to determine whether successful reperfusion (modified Thrombolysis In Cerebral Infarction >=2b), functional independence at 90 days (modified Rankin Scale score <=2), symptomatic intracranial hemorrhage, and 90-day mortality differed between those who underwent MT with the DS or the MS treatment pathway. Outcomes were meta-analyzed and the results expressed as adjusted relative risk (aRR) for the primary analysis and unadjusted relative risk (uRR) for secondary analysis. RESULTS: Eight studies including 2068 patients were selected, including one study reporting results fully adjusted for baseline characteristics. Patients undergoing MS had better functional independence than those undergoing DS (uRR=0.87, 95% CI 0.81 to 0.93; aRR=0.87, 95% CI 0.77 to 0.98). No difference was found between the treatment pathways in successful reperfusion (uRR=1.05, 95% CI 0.95 to 1.15; aRR=1.00, 95% CI 0.92 to 1.10), symptomatic intracranial hemorrhage (uRR=1.37, 95% CI 0.91 to 2.06; aRR, 1.53, 95% CI 0.79 to 2.98), and 90-day mortality (uRR=1.00, 95% CI 0.84 to 1.19; aRR=1.21, 95% CI 0.89 to 1.64). CONCLUSIONS: Patients who had an acute ischemic stroke admitted directly to a comprehensive stroke center (MS patients) with endovascular capacities may have better 90-day outcomes than those receiving DS treatment. However, major limitations of current evidence (ie, retrospective studies and selection bias) suggest a need for adequately powered studies. Multicenter randomized controlled trials are expected to answer this question. PMID- 30297542 TI - The semiotics of distal thrombectomy: towards a TICI score for the target vessel. PMID- 30297543 TI - The safety and effectiveness of the LVIS stent system for the treatment of wide necked cerebral aneurysms: final results of the pivotal US LVIS trial. AB - INTRODUCTION: The LVIS stent system (LVIS and LVIS Junior) is a self-expanding, retrievable, microstent system indicated for the treatment of wide-necked cerebral aneurysms (WNAs). The present pivotal study was performed to evaluate the safety and effectiveness of this device. METHODS: The US LVIS pivotal trial was a prospective, multicenter, single-arm, interventional study conducted at 21 US centers. The study enrolled 153 adults with WNAs of the anterior and posterior circulations. The study was conducted under good clinical practices and included independent adjudication of all adverse events. The primary effectiveness endpoint was defined as successful aneurysm treatment with the LVIS System as evidenced by complete (100%) aneurysm occlusion at 12 months on conventional angiography without retreatment and without significant (>=50%) stenosis of the treated artery at 12 months as determined by an independent core laboratory. The primary safety endpoint was defined as the rate of stroke or death within 30 days, or ipsilateral stroke or neurologic death with 12 months. RESULTS: One hundred and fifty-three patients enrolled at 21 investigational sites underwent attempted LVIS-assisted coil embolization. The mean age was 58.3+/-10.5 years and the majority of the participants (110/153, 71.9%) were female. Fifty-seven aneurysms (57/153, 37.3%) arose from the anterior cerebral artery, 43 (43/153, 28.1%) from the internal carotid artery, 17 (17/153, 11.1%) from the middle cerebral artery, 27 (27/153, 17.6%) from the basilar artery, six (6/153,3.9 %) from the PCA, and two from the vertebral artery. A single aneurysm arose from the superior cerebellar artery. The mean aneurysm dome height was 6.0+/-2.2 mm and mean width 5.5+/-2.3 mm. Mean neck width was 4.2+/-1.4 mm. A total of 22 participants presented for re-treatment of a previously ruptured (>30 days prior to treatment) target aneurysm. The primary effectiveness endpoint was observed in 70.6% (108/153) in the intent to treat population (ITT). Of the evaluable participants with follow-up 12-month angiography, 79.1 % (110/139) demonstrated complete occlusion- 92.1% (128/139) in this population demonstrated >=95% occlusion and 95% demonstrated >=90% occlusion (132/139). Eight participants (5.2%, 8/153) had at least one primary safety event in the ITT population. CONCLUSION: The LVIS stent system allows safe and highly effective coil embolization of WNAs.

B74, 427-435]. PMID- 30297544 TI - Laparoscopic cholecystectomy versus percutaneous catheter drainage for acute cholecystitis in high risk patients (CHOCOLATE): multicentre randomised clinical trial. AB - OBJECTIVE: To assess whether laparoscopic cholecystectomy is superior to percutaneous catheter drainage in high risk patients with acute calculous cholecystitis. DESIGN: Multicentre, randomised controlled, superiority trial. SETTING: 11 hospitals in the Netherlands, February 2011 to January 2016. PARTICIPANTS: 142 high risk patients with acute calculous cholecystitis were randomly allocated to laparoscopic cholecystectomy (n=66) or to percutaneous catheter drainage (n=68). High risk was defined as an acute physiological assessment and chronic health evaluation II (APACHE II) score of 7 or more. MAIN OUTCOME MEASURES: The primary endpoints were death within one year and the occurrence of major complications, defined as infectious and cardiopulmonary complications within one month, need for reintervention (surgical, radiological, or endoscopic that had to be related to acute cholecystitis) within one year, or recurrent biliary disease within one year. RESULTS: The trial was concluded early after a planned interim analysis. The rate of death did not differ between the laparoscopic cholecystectomy and percutaneous catheter drainage group (3% v 9%, P=0.27), but major complications occurred in eight of 66 patients (12%) assigned to cholecystectomy and in 44 of 68 patients (65%) assigned to percutaneous drainage (risk ratio 0.19, 95% confidence interval 0.10 to 0.37; P<0.001). In the drainage group 45 patients (66%) required a reintervention compared with eight patients (12%) in the cholecystectomy group (P<0.001). Recurrent biliary disease occurred more often in the percutaneous drainage group (53% v 5%, P<0.001), and the median length of hospital stay was longer (9 days v 5 days, P<0.001). CONCLUSION: Laparoscopic cholecystectomy compared with percutaneous catheter drainage reduced the rate of major complications in high risk patients with acute cholecystitis.

AB - The crystal structure of Cu5FeS4 (bornite) has been investigated using synchrotron X-ray powder diffraction at temperatures between 10 and 275 K. Diffraction data confirm that bornite crystallizes in the orthorhombic space group Pbca at 275 K. The unit-cell volume decreases continuously on cooling, but undergoes an abrupt contraction below ~65 K, where a first-order Pbca->Pca21 structural transition takes place. The primary active mode yielding the observed ordered structure corresponds to the irreducible representation Gamma2-, with wavevector (0,0,0). Pair distribution function analysis shows strong discrepancies between the local and the average structure. The average Fe-S bond length obtained through the EXAFS local probe is consistent with the values independently provided by X-ray powder diffraction data, strongly supporting the preferred location of Fe. PMID- 30297547 TI - Azulene revisited: solid-state structure, invariom modeling and lattice-energy minimization of a classical example of disorder. AB - The molecular and solid-state structure of azulene both raise fundamental questions. Therefore, the disordered crystal structure of azulene was re-refined with invariom non-spherical atomic scattering factors from new single-crystal X ray diffraction data with a resolution of d = 0.45 A. An unconstrained refinement results in a molecular geometry with Cs symmetry. Refinements constrained to fulfill C2v symmetry, as observed in the gas phase and in high-level ab initio calculations, lead to similar figures of merit and residual densities as unconstrained ones. Such models are consistent with the structures from microwave spectroscopy and electron diffraction, albeit they are not the same. It is shown that for the disorder present in azulene, the invariom model describes valence electron density as successfully as it does for non-disordered structures, although the disorder still leads to high correlations mainly between positional parameters. Lattice-energy minimizations on a variety of ordered model structures using dispersion-corrected DFT calculations reveal that the local deviations from the average structure are small. Despite the molecular dipole moment there is no significant molecular ordering in any spatial direction. A superposition of all ordered model structures leads to a calculated average structure, which explains not only the experimental determined atomic coordinates, but also the apparently unusual experimental anisotropic displacement parameters.

Three distinct phases have been identified. The high temperature alpha and low-temperature gamma phases share the same space group Pbca, whereas the intermediate beta phase is in the Pb21a subgroup of Pbca. In all phases molecules of (1) form well defined double layers, with PEt3 groups interlocking in planes perpendicular to c. On the molecular level, both phase transitions involve almost uniquely a conformational change of triethylphosphine: a gear-like rotation around the P-Au axis and concerted flips of the ethyl moieties. The mechanism of these transitions may be imagined as initiated by a rotation of a single PEt3 group in a double layer (a single gear movement), followed by adjacent phosphines adjusting their conformations as a result of steric strain. The structural changes underlying phase transitions are sequential, occurring layer-wise, the gamma->beta transition involving approximately every other layer in the crystal lattice, the beta->alpha yielding a total conformation change. The sequence of phase transitions results in a noticeable contraction of the crystal cell volume.

AB - Non-stoichiometry is considered to be one of the main problems limiting iron pyrite, FeS2, as a photovoltaic absorber material. Although some historical diffraction experiments have implied a large solubility range of FeS2-delta with delta up to 0.25, the current consensus based on calculated formation energies of intrinsic defects has lent support to line-compound behavior. Here it is shown that pyrite stoichiometry is relatively inflexible in both reductive conditions and in autogenous sulfur partial pressure, which produces samples with precise stoichiometry of FeS2 even at different Fe/S ratios. By properly standardizing in situ gas-flow X-ray diffraction measurements, no significant changes in the lattice parameter of FeS2 can be resolved, which portrays iron pyrite as prone to forming sulfur-deficient compounds, but not intrinsic defects in the manner of NiS2-delta. PMID- 30297550 TI - Determination of the miscibility gap in the solid solutions series of methylammonium lead iodide/chloride. AB - Perovskites are widely known for their enormous possibility of elemental substitution, which leads to a large variety of physical properties. Hybrid perovskites such as CH3NH3PbI3 (MAPbI3) and CH3NH3PbCl3 (MAPbCl3) are perovskites with an A[XII]B[VI]X[II]3-structure, where A is an organic molecule, B is a lead(II) cation and X is a halide anion of iodine or chlorine. Whereas MAPbCl3 crystallizes in the cubic space group Pm{?overline 3}m, MAPbI3 is in the tetragonal space group I4/mcm. The substitution of I by Cl leads to an increased tolerance against humidity but is challenging or even impossible due to their large difference in ionic radii. Here, the influence of an increasing Cl content in the reaction solution on the miscibility of the solid solution members is examined systematically. Powders were synthesized by two different routes depending on the I:Cl ratio. High-resolution synchrotron X-ray data are used to establish values for the limits of the miscibility gap which are 3.1 (1.1) mol% MAPbCl3 in MAPI and 1.0 (1) mol% MAPbI3 in MAPCl. The establishment of relations between average pseudo-cubic lattice parameters for both phases allows a determination of the degree of substitution from the observed lattice parameters.

AB - Furan/phenylene co-oligomer single crystals are considered as future materials for organic optoelectronics. Here, the effects of trifluoromethyl substituents on the crystallization, structure and optical properties of furan/phenylene co oligomer 1,4-bis{5-[4-(trifluoromethyl)phenyl]furan-2-yl}benzene are studied systematically. The solution growth methods and physical vapor transport result in the formation of three polymorphs depending on the growth method and the solvent. Single-crystal X-ray analysis reveals the crystal structures to correspond to H-, J- or mixed aggregates. All obtained crystals exhibit high photoluminescence efficiency and have optical properties which strongly depend on the crystal packing. Variable-temperature X-ray powder diffraction analysis shows the thermal transition of two forms (H- and J-aggregates) into a third one (mixed aggregate). Terminal trifluoromethyl groups induce weak intermolecular interactions which control the crystal packing and optical properties of co oligomer single crystals.

AB - Tetrachlorobenzenes represent one of the best known, but not yet fully understood, group of isomers of the structure-melting point relationship. The differences in melting temperatures of these structurally related compounds were rationalized in terms of the hierarchy and nature of formed noncovalent interactions, and the molecular aggregation that is influenced by molecular symmetry. The highest melting point is associated with the highly symmetric 1,2,4,5-tetrachlorobenzene isomer. The structures of less symmetrical 1,2,3,4 tetrachlorobenzene and 1,2,3,5-tetrachlorobenzene, determined at 270 and 90 K, show a distinct pattern of halogen bonds, characterized by the different numbers and types of interactions. The evolution of Cl...Cl/H distances with temperature indicates the attractive character of intermolecular interactions and their importance to the structural and thermodynamic parameters of isomeric compounds. The favoured Cl...Cl halogen bonds were found to play a decisive role in differentiating the melting temperatures of tetrachlorobenzene isomers. It was also found that, besides the molecular symmetry and ability to form specific intermolecular interactions, both the type and the distribution of interactions are the important factors responsible for the melting behaviour of the studied isomers. The observed preferences, in tetrachlorobenzenes, for the formation of specific noncovalent interactions correspond to the distribution of calculated partial atomic charges and to the magnitudes of electrostatic potential on the molecular surfaces as well as correlate with the enthalpy of melting parameters.

PMID- 30297555 TI - The accuracy of risk malignancy index in prediction of malignancy in women with adnexal mass in Basrah, Iraq. AB - Background: Adnexal masses indicate a variety of gynecological and nongynecological disorders, which may be benign or malignant. Early detection of malignancy is crucial to a proper planning of treatment and improvement of survival. Objective: To determine the accuracy of risk of malignancy index (RMI) in prediction of malignant adnexal mass. Subjects and Methods: This was a prospective multicenter study which included 101 women with adnexal masses. RMI2 with cutoff value of 200 was used to discriminate between benign and malignant tumors. Histopathological examination was used to confirm the final diagnosis. Results: Out of the studied women, 20.8% proved to have malignant tumors. The RMI showed a sensitivity of 100%, a specificity of 96.2%, a positive predictive value of 87.5%, and a negative predictive value (NPV) of 100%. The RMI identified malignant cases more accurately than any individual criterion in diagnosing ovarian cancer. The receiver operating characteristic analysis showed that the area under the curve of the RMI, CA 125, ultrasound, and menopausal status were significantly high with values of 1.0, 0.99, 0.86, and 0.85, respectively. Conclusion: The RMI is a simple sensitive, practical, and reliable tool in preoperative discrimination between benign and malignant adnexal masses that can facilitate selection of cases for timely referral to oncology center. PMID- 30297554 TI - Digital evaluation of the dimensional accuracy of four different implant impression techniques. AB - Aims: The aim of this study was to compare the dimensional accuracy of four different implant impression techniques of a mandibular edentulous model with five parallel implants. Materials and Methods: Five dental implants were placed in an edentulous mandibular model in parallel. A total of forty impressions were obtained using four different impression techniques. In Group 1 (G1) and Group 2 (G2), closed tray impressions with and without plastic caps, respectively, were used. In Group 3 (G3) and Group 4 (G4), open tray impressions with a direct splinted technique and an improved direct splinted technique, respectively, were used. All the impressions were poured with Type IV dental stone. Master model and study casts were scanned with a laser optical scanner and aligned by observing the superpositions of the anatomical landmarks using a software program. Statistical Analysis Used: Fifty measurements of the apical, coronal, and angular discrepancies of the master and study casts were obtained (n = 50) and statistically analyzed using a one-way analysis of variance and post hoc (least significant difference ) and Friedman's tests. Results: The lowest accuracy was obtained from G2 when the angular (1.48 degrees ), coronal (0.32 MUm), and apical (0.14 MUm) deviations were tested (P < 0.05), whereas no statistically significant differences were found among the other groups (P < 0.05). Conclusions: In cases with five parallel mandibular implants, improved accuracy was achieved using the direct splinted technique, the improved direct splinted technique, or the closed tray impression technique with snap on plastic caps.

AB - Background: There has been no comprehensive study on identifying the sociocultural characteristics and the factors affecting the number of relatives and/or friends accompanying patients. The purpose of this study was to identify these sociocultural characteristics and the factors affecting this. Materials and Methods: The research was designed as a cross-sectional, one-to-one interview study. A study population representing one in three patients aged over 18 years and presenting consecutively to the emergency department over a 1-month period was constituted with systematic sampling. A sample size of at least 4483 patients was planned with a 1% margin of error and 90% power. Results: Two thousand nine hundred and fifty (58.5%) of the 5046 patients included in the study were male. Patients' mean age was 38.4 +/- 17.4 years (median 34 years). At least one friend or relative accompanied 3690 (73.1%) patients, and the mean number of accompanying individuals was 1.50. A higher level of accompaniment and a higher mean number of accompanying individuals were determined in patients presenting to the emergency department outside working hours, with altered mental state, attending hospital for the first time, with chronic disease, requiring hospitalization, in illiterate patients, in patients who had not studied at university, in patients aged 65 or over, and in patients presenting to hospital and the emergency department for the first time compared to other parameters (<0.01 for all). Conclusion: The number of people accompanying patients increases with sociocultural factors such as gender, age, literacy, and education level. In addition, similar increase can be observed with patients coming to emergency department by ambulance or having a chronic disease or arrive with lost consciousness. PMID- 30297557 TI - Chemical analysis of uroliths: A two-center study of doctors' practice and perspective in South-East, Nigeria. AB - Introduction: Urolithiasis is a global disease condition secondary to a variety of factors, and sometimes associated with serious complications. Determination of stone composition is important in delineating causative factors. Knowledge of causative and precipitating factors aids patient management and prevention of recurrence. Objective: The authors' aim was to evaluate the practice and perspective of doctors regarding chemical analysis of stones in management of urolithiasis. Materials and Methods: This comparative cross-sectional study was done between December 2016 and May 2017 in two teaching hospitals in South-East, Nigeria. Data were collected using self-administered questionnaires. Results: In all, 88 doctors with mean (standard deviation) age of 37.3 (9.5) years participated in the study. Urinary bladder stones were the most frequently managed, 51 (58.0%); 45 (51.1%) participants do not routinely send stones for chemical analysis. All respondents (100%) agreed that stone analysis is beneficial to patient management. Conclusion: This study showed that in spite of all respondents affirming that chemical analysis of uroliths is beneficial to patient management, more than half of respondents do not routinely send stones for analysis. PMID- 30297558 TI - Frequency of audiological complaints in patients with fibromyalgia syndrome and its relationship with oxidative stress. AB - Aim: Central sensitization-related neuroaudiological symptoms are frequently seen in patients with fibromyalgia syndrome (FMS). This study aimed to evaluate the audiological signs and symptoms in patients with FMS and explore their relationship with oxidative stress markers. Methods: This prospective controlled cross-sectional study compared the serum myeloperoxidase, superoxide dismutase, glutathione peroxidase (GPx), nitric oxide (NO), and malondialdehyde (MDA) concentrations in 44 patients with FMS diagnosed according to the 2010 American College of Rheumatology criteria and 44 healthy volunteers. FMS severity was assessed using the visual analog scale and Fibromyalgia Impact Questionnaire. An audiological assessment including vocalizations, vertigo, balance problems, and hearing problems was done to all participants. Results: The two groups were of similar age (P = 0.24), gender (P = 0.40), and weight distribution (P = 0.6). Vertigo, tinnitus, hearing, and balance complaints (P = 0.01/P = 0.00/P = 0.00/P = 0.01) were significantly higher in the FMS group. All subunits and total scores of dizziness handicap inventory were significantly higher (P = 0.00/P = 0.00/P = 0.01/P = 0.01) in the FMS group. An antioxidant GPx and oxidant parameters such as NO and MDA were found to be significantly higher (P = 0.00/P = 0.01/P = 0.02). The hearing assessments at frequencies between 250 and 12,000 Hz showed a significant difference between the two groups (high hearing frequencies in the FMS group) in audiometry. No significant difference was found between the two groups in terms of the presence of stabilo-acoustic reflex, intraaural pressure, and compliance (P = 0.18/P = 0.33/P = 0.41) in tympanogram. Conclusions: Patients with FMS have high levels of oxidative stress markers (GPx, NO, and MDA), highly frequent audiological symptoms with high hearing frequencies in audiometry, independent of disease severity. PMID- 30297559 TI - Preoperative Vitamin D levels and respiratory complications of general anesthesia. AB - Aims: This research aims to investigate whether there is a correlation between the respiratory complications occurring in patients under general anesthesia and preoperative Vitamin D levels. Settings and Design: The study was a prospective observational study. Materials and Methods: This study included 95 adult cases. The cases had total 25-hydroxyvitamin D (25OHD) levels identified in blood samples before the operation. Patients given routine general anesthesia and were assessed in terms of respiratory complications during anesthesia induction, extubation, anesthesia recovery, and the first 24-h postoperative. Statistical Analysis Used: The Shapiro-Wilk test, Student's-t-test, one-way ANOVA test, Pearson correlation coefficient, and Chi-square tests were used. Results: The mean 25OHD vitamin level identified in the preoperative period was 13.00 +/- 6.57 ng/mL, with 25OHD vitamin levels found to be significantly low in female cases compared to male cases (P < 0.05). There was a statistically significant negative relationship between age and 25OHD vitamin levels identified (P = 0.045). When assessed in terms of surgery types, there was no significant difference found in Vitamin D levels in terms of surgery type. When examined for complications in the induction, extubation period, and postoperative recovery period, there was a significant difference identified between 25OHD vitamin levels and these complications (P < 0.01). Conclusions: This research observed that patients with low preoperative 25OHD vitamin levels encountered respiratory complications related to general anesthesia more often. Especially, in the early postoperative period, there is a very significant difference between complications and low 25OHD vitamin levels.

AB - Objective: The objective of this study is to compare the effectiveness of final irrigation with chitosan, ethylenediaminetetraacetic acid (EDTA), and citric acid (CA) on a resin-based sealer (AH plus sealer [Dentsply DeTrey, Konstanz, Germany]) penetration into dentinal tubules using confocal laser scanning microscopy. Materials and Methods: Seventy recently extracted human mandibular premolars were instrumented and irrigated with sodium hypochlorite (NaOCl), then divided into four groups according to the final irrigation regimen used: (1) the EDTA group: 17% EDTA + 2.5% NaOCl, (2) the CA group: 10% CA + 2.5% NaOCl, (3) the chitosan group: 0.2% chitosan + 2.5% NaOCl, and (4) the control group: 2.5% NaOCl. All teeth were obturated using the cold lateral condensation technique with gutta-percha and AH Plus sealer labeled with fluorescent dye. The apical 2 mm of specimen was discarded, and slices were obtained for apical, middle, and coronal thirds of the root with 1 mm intervals. Maximum, mean, and percentage of sealer penetration (SP) inside tubules were measured using confocal laser scanning microscopy. Results: The percentage of SP was significantly higher in chitosan, EDTA, and CA group than control group for coronal thirds (P < 0.05), whereas there was no significant difference among all groups for middle and apical thirds. Chitosan and EDTA showed increased mean values of SP depth for middle thirds (P < 0.05). In all sections, the maximum depth of SP was significantly lower in EDTA group than other groups (P < 0.05). Conclusions: Chitosan, EDTA, and CA significantly improved the percentage of SP for coronal thirds. PMID- 30297562 TI - Primary principles in developing scale with Rasch analysis: Portfolio anxiety assessment. AB - Background: Rasch model is a useful method for developing a new scale. This study aims to determine the fitting between data obtained from answers for a portfolio anxiety scale and Rasch model and describes how the scale can be modified to increase the fitting through different steps. Materials and Methods: A portfolio scale was applied to 171 students of the Faculty of Medicine, Ondokuz Mayis University. The partial credit model was used, and fit statistics were assessed to determine the fitting of the data to Rasch model. Person separation index (PSI) was used for reliability. Results: For a satisfaction subscale, the average item fit residual value was 0.47 and the average person fit residual value was 0.29. For the item-trait chi2 interaction, P = 0.655 and PSI = 0.81. For a writing anxiety subscale, the average item fit residual value was 0.08 and the average person fit residual value was -0.24. For the item-trait chi2 interaction, P = 0.698 and PSI = 0.73. For a reflection anxiety subscale, the average item fit residual value was 0.64 and the average item fit residual value was 0.64. For the item-trait chi2 interaction, P = 0.195 and PSI = 0.73. Conclusion: The validity and reliability of Rasch analysis portfolio scale were analyzed, and items that worked well were included in the study. The results show that Rasch model provides a more accurate analysis for developing and adapting scales. Both the fit statistics and fit graphs help improve the analyses. PMID- 30297561 TI - Effect of green gold nanoparticles synthesized with plant on the flexural strength of heat-polymerized acrylic resin. AB - Purpose: The aim of this study was to investigate the effect of gold nanoparticle on the flexural strength of polymethyl methacrylate (PMMA). Materials and Methods: PMMA specimens (65 mm * 10 mm * 3.3 mm) containing different sizes (45 nm, 55 nm, and 65 nm) and concentrations (0.05% and 0.2%) of gold nanoparticles were prepared, along with a control group containing no added nanoparticles. Flexural strength of all specimens was measured, and one-way ANOVA and Tukey Kramer post hoc multiple comparisons tests were performed to identify statistical differences between groups. Results: The addition of gold nanoparticles increased the flexural strength of acrylic resin. Significantly greater increases were obtained with lower concentrations (0.05%) when compared to higher concentrations (0.20%). Conclusion: Differences in concentrations of gold nanoparticles added to PMMA have significantly different effects on PMMA flexural strength, whereas differences in sizes of gold nanoparticles added to PMMA do not significantly affect its flexural strength. Accordingly, adding gold nanoparticles to PMMA may enhance the mechanical properties of denture bases used in clinical practice. PMID- 30297563 TI - Dental anxiety and oral health-related quality of life in children following dental rehabilitation under general anesthesia or intravenous sedation: A prospective cross-sectional study. AB - Purpose: The study aimed to investigate dental anxiety and oral health-related quality of life among children undergoing dental rehabilitation under general anesthesia (GA) and intravenous sedation (IVS). Materials and Methods: Participants were 99 healthy children aged 3-5 or 6-12 years operated under GA or IVS. Dental anxiety before treatment and 1 month postoperatively were measured using the Frankl behavior scale (FBS), the venham picture test (VPT), the early childhood oral health impact scale (ECOHIS), and the children's fear survey schedule-dental subscale (CFSS-DS). Data were analyzed using Student's t-test and Mann-Whitney U-test. Results: ECOHIS scores decreased in all groups. VPT scores increased in the 3-5-year-olds treated under GA (P = 0.003). Postoperative CFSS DS anxiety scores were lower in IVS groups. FBS scores were significantly higher for both age groups (P < 0.001). There was no effect of numbers of extracted or treated teeth. Conclusions: Dental rehabilitation under GA and IVS improved the quality of life and dental behavior. In the 6-12-year-olds, there was no statistically significant difference between children undergoing dental operations under GA and those undergoing dental operations under IVS. Dental anxiety decreased in 3-5-year-olds after treatment under GA but not after IVS.

AB - Objectives: The aim of this study was to evaluate the efficacy of using erbium, chromium-doped:yttrium scandium gallium garnet (Er,Cr:YSGG) laser-treated dentine in a dentine barrier test device. Materials and Methods: The test materials (G BondTM and VitrebondTM) were applied onto laser-treated or laser-untreated dentine discs. After 24 h of exposure with perfusion of the test chamber, cell survival was evaluated based on enzyme activity and compared to a nontoxic control material. The mean of the control was set to 100% viability. Data were analyzed using the one-way analysis of variance and the Tukey's honest significant difference tests. Results: The responses of bovine pulp-derived cells after exposure to G-Bond and Vitrebond on Er,Cr:YSGG laser-treated and laser untreated dentin were statistically different from negative control group (P < 0.05). Conclusion: Er,Cr:YSGG laser treatment was not successful enough in decreasing the cytotoxic effects of the dental materials. Different parameters of Er,Cr:YSGG laser or different laser types could be investigated as an alternative to minimizing the cytotoxic effects of dental materials. PMID- 30297565 TI - The effectiveness of erbium: Yttrium-aluminum-garnet laser on enamel conditioning: An In vitro study. AB - Objectives: The purpose of this in vitro study was to investigate the effect of three different enamel surface conditioning procedures on the bonding strength of two resin-based filled fissure sealants. Material and Methods: Freshly extracted, 48 third molar teeth were used in this study. Teeth were randomly divided into three main groups as the phosphoric acid etched, erbium: Yttrium-aluminum-garnet (ER: YAG) laser etched, and the phosphoric acid plus ER: YAG laser-etched groups. The main groups further divided into two subgroups as Clinpro or Fissurit FX applied. After preparation of the enamel surfaces and application of the sealants, the samples were subjected to shear bond strength test. Results: According to statistical analysis with one-way ANOVA, the bonding strength values of the phosphoric acid groups were found significantly higher than those values obtained from the ER: YAG laser and ER: YAG laser plus phosphoric acid groups (P < 0.001). Conclusion: As a result of the study, it has been concluded that the laser application alone has no additional benefit to the acid application in terms of bonding strength. PMID- 30297566 TI - Comparing the interpretation of emergency department computed tomography between emergency physicians and attending radiologists: A multicenter study. AB - Introduction: Computed tomography (CT) interpretation in the emergency department is one of the vital issues that should be carried out rapidly and accurately. The objective of this study was to examine the interpretation accuracy of emergency physicians (EPs) regarding CT scans at the emergency department for traumatic and nontraumatic purposes. Materials and Methods: The study that was carried out as a prospective, observational study was completed at four centers during 1 year. Results: Accuracy ratios of CT interpretations of EP regarding cranial injuries, thoracic injuries and vertebral spine injuries are above 95% in addition to the fact that the concordance's with the final result are perfect, the concordance with the final results of the CT interpretations of EP for abdominal injuries was moderate (<0.75). Accuracy ratios of the CT interpretations of EP for nontrauma patients were above 90% for brain hemorrhage and chest injuries and that the concordance with the final results was perfect (>=0.75). The CT interpretation accuracy rates of EP for spontaneous pneumothorax and aortic aneurysm/aortic dissection cases were 100%. CT interpretation rate of EP for pulmonary embolism was 89.4%, whereas the level of concordance with the final results was moderate (<0.75). Whereas the CT interpretation accuracy rates of EP for nontraumatic abdominal injuries varied between 83.3% and 93.1%, their levels of concordance with the final results were moderate (<0.75). Conclusions: The CT interpretations for abdominal traumatic patients in addition to pulmonary embolism and acute nontraumatic abdominal injuries should be carried out more carefully. PMID- 30297567 TI - An audit of the diagnosis and reporting of soft tissue sarcomas at the Lagos University Teaching Hospital. AB - Background: : The effective management of patients with cancer is predicated on the right diagnoses and other relevant parameters included in the pathology report. This is particularly important in soft tissue pathology where arriving at the right diagnosis is often challenging. The aim of this study, therefore, was to perform an audit of sarcoma diagnosis and reporting in our institution. Methods: Slides of soft tissue sarcomas diagnosed in our institution over a 5 year period were reviewed with specialist soft tissue pathologists. Ancillary immunohistochemistry and fluorescent in situ hybridization were performed where necessary. The contents of the reports were assessed using a diagnostic checklist developed by the Association of Directors of Anatomic and Surgical Pathology. Results: Fifty-five of the 62 patients studied (88.7%) were correctly identified as sarcomas. However, the correct diagnoses were made in only 27 patients (43.6%). Kaposi sarcoma and dermatofibrosarcoma protuberans were the most recognized sarcomas, while leiomyosarcoma, myxofibrosarcoma, and malignant peripheral nerve sheath tumor were the least recognized sarcomas. The most reported parameters included the histologic type (100%) and size (89.7%), while the percentage of necrosis (0%) and the stage (0%) were the least reported parameters. Conclusion: A pattern based approach is important for the accurate diagnosis of soft tissue sarcomas. Some essential prognostic parameters and information needed for management were not included in the histopathology reports. The adoption of a structured reporting format and multidisciplinary team meetings will help to ensure the inclusion of such important information in the pathology report. PMID- 30297568 TI - Effects of thoracic epidural or intravenous analgesia on the neutrophil-to lymphocyte ratio in thoracotomy cases. AB - Background and Purpose: Postoperative pain is a significant problem in thoracotomy patients. Our aim in this study was to investigate the relationship between postoperative pain and neutrophil-to-lymphocyte ratio (NLR) which is a marker of acute inflammatory response. Materials and Methods: Thoracic epidural or intravenous analgesia was administered to thoracotomy patients who elected to undergo a planned surgery. Patients were divided into two groups according to the analgesia method applied postoperatively. Thoracic epidural analgesia was recorded as Group 1 and intravenous analgesia as Group 2. Whole blood counts were recorded from preoperative and postoperative 24th- and 48th-hour routine blood samples, and NLRs were recorded as retrospective file scanning. Postoperative 24th- and 48th-hour NLRs and preoperative NLR values were recorded. Results: Demographic data of the patients included in the study were similar except for age. Preoperative NLR was significantly higher in Group 1 at 3.50 (P = 0.004) than in Group 2 at 2.51. Postoperative NLRs were similar among both groups. Postoperative NLR values at both the 24th- and 48th-hour increased by4.9 times in Group 1 and 9.23 times in Group 2 from the 24th-hour preoperative period, when the preoperative NLRs were evaluated. The rate of increase in Group 1 was significantly lower than in Group 2 (P = 0.006). Conclusion: Postoperative NLR alterations when compared with preoperative values were related to the analgesic regimen used. PMID- 30297569 TI - Impact of cowpea fortified cookies on anthropometric and micronutrient status of primary school children: A randomized, single-blind controlled trial. AB - Background: Micronutrient deficiencies are public health problems among school children. Food-to-food fortification may reduce the prevalence of these deficiencies. Aim: To assess the impact of cowpea (Vigna sinensis) fortified cookies on weight, height, body mass index (BMI), hemoglobin, serum vitamin A, and zinc status of primary school children aged 6-12 years. Methods: A randomized single-blind controlled trial was conducted for 4 weeks among 17 pupils who were voluntarily recruited and randomly assigned to experimental (Group A) and control (Group B) groups. Group A was fed wheat cookies incorporated with cowpea in a ratio of 60:40, while Group B received 100% wheat cookies. Data were collected through questionnaire, anthropometry, and biochemical analysis. Statistical analysis involved descriptive statistics and t-test. Significance was set at P < 0.05. Results: The study involved 17 school children out of which 10 (58.8%) were boys and 7 (41.2%) were girls; 12 (70.6%) were 10-12 years old and 4 (23.5%) were in lower primary (1-3). Group A had increases in hemoglobin (15.5%), serum ferritin (28.3%), serum zinc (38.9%), weight (3.0%), BMI (3.4%), and serum vitamin A (26.3%); only increases in hemoglobin, serum ferritin, and vitamin A attained significance (P < 0.05). Though there was increase in weight (6.1%), BMI (5.4%), hemoglobin (5.0%), serum ferritin (16.4%), zinc (20.8%), and vitamin A (17.5%) of Group B, these increases were not significant (P > 0.05). Group A had significantly (P < 0.05) higher serum ferritin (51.3 MUg/L) than Group B (44.7 MUg/L). Conclusion: Consumption of cowpea fortified cookies had significant positive effects on hemoglobin, serum ferritin, and vitamin A levels of school children and should be encouraged at household and industrial levels. PMID- 30297570 TI - Severe falciparum malaria in children in Enugu, South East Nigeria. AB - Introduction: Severe malaria remains one of the leading causes of morbidity and mortality in sub-Saharan Africa and parts of Asia despite several efforts in prevention and management. The prevalence and pattern of presentation may vary from one location to another and from one age group to another. Objectives: This study was undertaken to review the prevalence and pattern of severe malaria among children presenting in the two tertiary hospitals in Enugu, south-east Nigeria. Methods: The case records of children presenting with malaria in the two tertiary hospitals in the state were retrieved and the necessary information were obtained using a structured questionnaire. Results: The children aged from 1 month to 184 months (15 years), with a median age of 36 months and mean age of 49.2 +/- 42.7 months. About two-thirds (68/102, 66.7%) of the children were under the age of 5 years, with only 6 of them (8.8%) being 6 months and below. There were significantly more males than females (chi2 = 6.48, P = 0.01); with a M:F ratio of 1.55:1. The peak of presentation was from August and November. Prostration, respiratory distress and severe anaemia were the commonest features of severe malaria, while shock, acute renal failure and abnormal bleeding were the least presenting features Of all the features, only severe anaemia was significantly related to age, (chi2 = 5.027, P = 0.02). Sixty-one (59.8%) of the children had one or more co-morbidities. There were 2 deaths, giving a case fatality rate of 1.96%. Conclusion: Early presentation will significantly reduce blood transfusions, prolonged admission and death in children with severe malaria. PMID- 30297571 TI - The effect of gender differences in protracted hiccups. AB - Background: Although little importance is attached to hiccups, they may be associated with several diseases. The purpose of this study was to investigate the effects of gender differences on types of hiccups and the relation with diseases involved in the etiology. Materials and Methods: Patients presenting to the Kirikkale University Medical Faculty Hospital with hiccups were investigated retrospectively. Patients' age, sex, duration of hiccups, additional diseases, advanced imaging results, laboratory tests, and clinical follow-up were recorded. Patients were divided into two groups; Group transient hiccup (TH) consisted of subjects with a duration of hiccups less than 48 h, and Group protracted hiccup (PH) of patients with a duration exceeding 48 h. The Chi-square test was used for comparisons, and P < 0.05 were regarded as significant. Results: Eighty-four patients were enrolled, 44.1% (n = 37) in Group TH, and 55.9% (n = 47) in Group PH. Male patients comprised 67.5% (n =25) of Group TH and 89.4% (n = 42) of Group PH (P = 0.027). The conditions most associated with hiccups were gastrointestinal system (GIS) diseases. Correlation was determined between GIS diseases and male gender (P = 0.034), no relation between other system diseases and gender. Correlation was determined between GIS diseases and protracted hiccups (P = 0.037), but no relation between other system diseases and type of hiccups. Conclusion: Protracted hiccups are more common in males. This gender variation applies particularly to hiccups of GIS origin. PMID- 30297572 TI - Cancer-testis antigen GAGE-1 expression and serum immunoreactivity in hepatocellular carcinoma. AB - Aim: To explore the use of cancer-testis antigen G antigen 1 (GAGE-1) in the diagnosis and potential therapeutic targeting of hepatocellular carcinoma (HCC), we measured the expression of GAGE-1 protein levels in HCC tissues and its serum immunoreactivity in HCC patients. Materials and Methods: We detected the expression of GAGE-1 protein in HCC by immunohistochemistry (IHC). We then analyzed the clinical significance of GAGE-1 expression in HCC with respect to clinicopathological parameters. We observed positive anti-GAGE-1 antibody reactivity in HCC patient serum, liver cirrhosis patients (LC), hepatitis B patients (HB), and normal human individuals (NHS) by enzyme-linked immunosorbent assay. Results: The IHC results showed that the positive rates of GAGE-1 protein expression in cancer tissues and adjacent tissues were 43.3% (26/60) and 5% (3/60), respectively. The expression level of GAGE-1 protein in HCC tissues was significantly higher than that in tumor-adjacent tissues (P < 0.05). Positive GAGE-1 protein expression was not correlated with clinicopathological parameters (P > 0.05). Positive serum anti-GAGE-1 antibody reactivity in HCC patients, LC, HB, and NHS was 23.33% (14/59), 13.1% (8/61), 3.3% (2/60), and 3.4% (2/59), respectively. The frequency of anti-GAGE-1 antibody-positive sera in HCC patients and LC was significantly different than that in HB and NHS (P < 0.01), but no significant differences were found between HCC patients and LC (P = 0.485) or between HB and NHS (P = 0.410). Positive anti-GAGE-1 antibody reactivity was not correlated with clinicopathological parameters (P > 0.05). Conclusion: These data illustrate that the GAGE-1 protein exhibits moderate cancer-restricted pattern of expression and immunogenicity, laying the foundation for the application of GAGE 1 in immunotherapy and for the diagnosis of HCC. PMID- 30297573 TI - A community-based surveillance of gastrointestinal helminthiasis among pregnant women in Ibadan, South West Nigeria. AB - Background: : Intestinal helminthiasis is a major public health problem in Africa. Helminthic infection in pregnant women causes loss of appetite, poor nutrient absorption, gastrointestinal impairment, iron deficiency, and iron deficiency anemia resulting in low birth weights and preterm births. The main aim of this study is to assess the prevalence of helminthic infections in pregnant women in rural and peri-urban communities of Ibadan. Materials and Methods: : A cross-sectional descriptive study was carried out at the antenatal clinics of 12 selected primary health centers and mission homes in Ibadan, Nigeria. Open- and closed-answer questionnaires were administered to 604 consenting pregnant women, who provided fresh stool samples for microscopy. Helminthic quantification was carried out by the Kato-Katz technique. Proportions were compared using Chi squared with IBM(r) SPSS(r) Statistics 21 for analysis. Statistical significance was set at P < 0.05. Results: : Eighty-nine stool samples (14.7%) were positive for helminthiasis. Most had roundworms (13.6%); 13 (2.2%) had hookworms. The mean arithmetic eggs per gram of feces were 2,124 and 248, respectively. No participant had a heavy intensity infection; nearly all were of low intensity. Participants (P = 0.005) and their husbands (P = 0.005) who had higher education were less likely to have helminthiasis. Conclusion: These communities are classified as Category III, having a low prevalence and low intensity infection. Therefore, prophylactic anti-helminthic treatment in pregnancy is not recommended. The inverse relationship with education may be a function of better living conditions. Better hygiene should be advocated. PMID- 30297574 TI - Intrauterine insemination in ovulatory infertile patients. AB - Aim: Although there are many studies in literature comparing intrauterine insemination (IUI) and timed intercourse, there are only a few studies examining the use of clomiphene citrate (CC) in ovulatory infertile patients. The aim of this study was to compare IUI following CC-induced ovulation and timed intercourse following CC-induced ovulation in ovulatory infertile patients. Methods: Hundred patients who had IUI or timed intercourse following ovulation induction (OI) via CC between 2012 and 2014 are prospectively scanned. Both groups were consisted of 50 patients. Both in groups 1 and 2 patients, the treatment with clomiphene citrate was started on the 3rd day of the menstrual cycle with a dose of 50 mg/day and was continued for 5 consecutive days. On the 13th day of the cycle, the patients were called for examination and folliculometry tests were performed via transvaginal ultrasonography. Human chorionic gonadotropin (HCG, a prepared syringe containing 250 MUg/0.5 ml [6,500 IU equivalent] choriogonadotropin alpha) was given to all patients with a sufficient size follicle (18-20 mm). Group 1 patients were recommended to have coitus regularly for a week after the HCG treatment. In group 2, IUI was performed 36 h after the HCG treatment. Results: Clinical pregnancy was provided in 28 patients in 100 patients. In group 1, the pregnancy rate per person was 6%, the pregnancy rate per cycle was 2.3%, and live birth rate was 6%. In group 2, the pregnancy rate per person was 22%, the pregnancy rate per cycle was 8.3%, and live birth rate was 23%. A statistically significant difference was observed between groups 1 and 2 in terms of pregnancy per person rate, pregnancy per cycle rate, and live birth rate. Conclusion: In the patients who had OI via CC, the pregnancy rates obtained with IUI were statistically significantly higher than timed intercourse. PMID- 30297575 TI - Benefits of anticitrullinated peptides examination in rheumatoid arthritis. AB - Background: Anti-citrullinated peptides antibodies (ACPA) are specific for rheumatoid arthritis and have been implicated in disease pathogenesis. ACPA examination is a new component of ACR/EULAR 2010 classification criteria for rheumatoid arthritis. ACPA positivity predicts a more erosive disease course with severe joint damage and extra-articular manifestations. Objectives: To evaluate the benefits of ACPA examination in patients with early undifferentiated arthritis and patients with rheumatoid arthritis. Methods: We examined patients with arthritis and tested them for ACPA positivity. In every individual patient we evaluated if ACPA examination was necessary to establish the diagnosis of rheumatoid arthritis, or to change treatment, or if the diagnosis could have been established without ACPA examination (ACR/EULAR 2010 classification criteria was met without ACPA scoring). Results and Conclusions: The study was placed in Slovak Republic. We examined 833 patients with arthritis. There were 43 patients, or 62% of a subgroup of 69 who were ACPA positive whose ACPA examination was not needed-ACR/EULAR criteria was met without ACPA scoring. This number represents 5.1% of the total number examined. There were 15 patients, or 22% of the subgroup and 1.8% of the total whose diagnosis was revised to rheumatoid arthritis due to ACPA positivity-ACR/EULAR criteria were met solely with ACPA scoring. There were 11 patients (16% and 1.3%) whose medication was changed due to ACPA positivity. ACPA examination is useful in 3.1% of all examined patients. When we correlate data on ACPA positive patients, 38% of the patients profit from ACPA examinations. Considering the relatively low price of ACPA testing, this examination should not be excluded. PMID- 30297576 TI - Metastatic squamous cell cancer with unknown primary origin in the mediastinal lymph node. AB - Metastatic tumors with unknown primary origin are a group of heterogeneous tumors with undetectable primary tumor site on admission. They have the common properties of rapid and aggressive progression and unpredictable metastases. They form 3%-5% of all cases with cancer and the fourth-most common cause of cancer related deaths. The histological type of these tumors is commonly (90%) adenocarcinoma, whereas 5% are squamous cell carcinomas. Metastasis is observed in the liver, lungs, and bones. Mediastinal lymph node metastasis is extremely rare. They have a poor prognosis and the mean survival is shorter than a year. The case we have presented is a rare case due to its mediastinal lymph node involvement among tumors with unknown origin and squamous cell histological subtype. PMID- 30297577 TI - Crohn's disease with positive Ziehl-Neelsen stain: Three case reports. AB - Because of the similarity of the clinical symptoms, endoscopic, and pathological features, the differential diagnosis between Crohn's disease (CD) and intestinal tuberculosis (ITB) remains difficult, especially in a high-incidence area of tuberculosis (TB). Here we reported three patients with positive Ziehl-Neelsen stain in endoscopic mucosal biopsy specimens. They had a poor response to anti-TB therapy but a good response to immunosuppresses, infliximab, or surgery, and were finally diagnosed as CD. It was not clear that they were CD concomitant with mycobacteria infection or CD induced by mycobacteria infection. Further studies including more clinical cases and related animal models are needed. Our cases highlight the importance of considering the presence of CD in patients with positive Ziehl-Neelsen stain, which were failure to respond to anti-TB treatment. PMID- 30297578 TI - Time-dependent cervical vagus nerve stimulation and frequency-dependent right atrial pacing mediates induction of atrial fibrillation. AB - OBJECTIVE: This study aimed to investigate the effects of right cervical vagus trunk simulation (RVTS) and/or right atrial pacing (RAP) on the induction of atrial fibrillation (AF). METHODS: Twenty-four healthy adult dogs were randomly divided into four groups: RAP groups comprising RAP500 (RAP with 500 beats/min) and RAP1000 (RAP with 1000 beats/min) and RVTS groups comprising RVTS and RAP500+RVTS. All dogs underwent 12-h intermittent RAP and/or RVTS once every 2 h. The AF induction rate, AF duration, atrial effective refractory period (ERP), and dispersion of ERP (dERP) were compared after every 2 h of RAP or/and RVTS. RESULTS: All groups had successful AF induction. The RAP1000 group had the highest AF induction rate and the longest AF duration. The RAP1000 group also had a shortened ERP in comparison to the other groups as well as the maximum dERP. Compared to the RAP500 group, RAP500+RVTS had an increased capacity to induce AF as measured by the AF induction rates, AF duration, ERP, and dERP. CONCLUSION: Increased tension in the vagus nerve and the intrinsic cardiac autonomic nervous system plays an important role in AF induction through different potential mechanisms. Interventions involving the vagus nerve and/or intrinsic cardiac autonomic nervous system can be a future potential therapy for AF. PMID- 30297579 TI - Evaluation of the effect of non-ergot dopamine agonists on left ventricular systolic function with speckle tracking echocardiography. AB - OBJECTIVE: Parkinson's disease (PD) is a neurological disorder, and ergot dopamine agonists (DAs) are no longer usually preferred in the treatment due to the increased risk of valvular heart disease. Some recent studies have shown that commonly used non-ergot DA also increases the risk of heart failure. On the other hand, there are studies showing conflicting data about this relationship. The aim of the present study was to investigate the cardiac effects of non-ergot DAs in patients with PD using echocardiography. METHODS: Conventional echocardiography and two-dimensional (2D) speckle tracking strain echocardiography were performed to determine the possible systolic dysfunction prior to the development of apparent systolic heart failure. Ninety-one (55 male, 64+/-10 years) patients with PD were included in the study. Furthermore, 25 subjects with newly diagnosed PD and using no drug were enrolled as the control group. All patients were divided into groups according to their medication. Patients using levodopa were classified as Group 1 (36), levodopa+pramipexole as Group 2 (27), and levodopa+ropinirole as Group 3 (28). RESULTS: Left ventricle dysfunction with non ergot DA use in patients with PD was not established with conventional echocardiographic evaluation. For 2D strain analysis, global longitudinal strain values were obtained as -18.5%, -18.5%, and -18.9% in the groups, respectively. Strain and strain rate values of the left ventricle were not different between the groups (p=0.816 and p=0.881, respectively). CONCLUSION: There was no significant relationship between left ventricular dysfunction and use of non ergot DA in patients with PD. Similar results were obtained in strain analysis showing left ventricular subclinical dysfunction. Our study appears to confirm the safety of non-ergot DA in the point of heart failure risk. To our knowledge, this is the first study to evaluate the effect of this group of drugs on subclinical left ventricular systolic function. PMID- 30297580 TI - Role of microcirculatory function and plasma biomarkers in determining the development of cardiovascular adverse events in patients with peripheral arterial disease: A 5-year follow-up. AB - OBJECTIVE: The aim of this long-term follow-up study was to investigate the association of local and systemic cardiovascular complications with endothelium dependent and-independent microvascular relaxations and blood biomarkers and biochemicals in patients with peripheral arterial disease (PAD) caused by atherosclerosis. METHODS: This prospective study included 67 patients with PAD who had not undergone any endovascular intervention, peripheral arterial surgery, or major amputation. Changes in the microvascular blood flow were measured using laser Doppler imaging after iontophoresis of acetylcholine (ACh) and sodium nitroprusside (SNP). The biochemical markers of high sensitivity C reactive protein (hs-CRP), nitric oxide (NO), total antioxidant capacity (TAC), asymmetric dimethyl arginine (ADMA), and hydrogen sulfide (H2S) levels were measured from blood samples. All the patients were followed up for 5 years to determine the development of cardiovascular adverse events (CVAEs) and major amputation. At the end of the follow-up period, the patients were classified into two groups: those who had a CVAE [CVAE (+)] and those who did not experience CVAE [CVAE (-)]. Parameters such as demographic features, atherosclerotic risk factors, chronic ischemia category, microvascular endothelial functions, and plasma biomarkers were compared between the groups. RESULTS: A total of 67 patients comprising 61 (91%) males and 6 (9%) females with a mean age of 62.3+/-9.7 years were included. During the follow-up period, 29 patients had CVAE (43.3%) and 38 patients did not have CVAE (56.7%). There was no difference between the groups in terms of ACh and SNP-induced vasodilation responses. Plasma high density lipoprotein (HDL) cholesterol values were lower in the CVAE (+) group [(CVAE+HDL: 38.4+/-9.1), (CVAE-HDL: 44.7+/-11.1), p=0.02]. Plasma hs-CRP values were significantly higher in the CVAE (+) group [(CVAE+ hs-CRP: 14.3+/-20.6), (CVAE-hs-CRP: 5.9+/-10.9), p=0.004]. No significant difference was observed between the groups in terms of plasma biomarkers and other biochemical levels. CONCLUSION: Based on the study findings, it was concluded that only low plasma HDL and high hs-CRP levels were risk factors for the development of CVAEs during follow-up of patients with PAD. PMID- 30297581 TI - Long-term outcomes in patients who underwent surgical correction for atrioventricular septal defect. AB - OBJECTIVE: The follow-up results of patients operated for atrioventricular septal defect (AVSD) during 1996-2016 at Baskent University are presented. METHODS: Data obtained from hospital records consists of preoperative echocardiographic and angiographic details, age and weight at surgery, operative details, Down syndrome presence, postoperative care details, early postoperative and latest echocardiographic findings and hospitalization for reintervention. RESULTS: A total of 496 patient-files were reviewed including 314 patients (63.4%) with complete and 181 (36.6%) with partial AVSD (48.4% of all patients had Down syndrome). Atrioventricular (AV) valve morphology was Rastelli type A in 92.2%, B in 6.5%, and C in 1.3% of patients. The operative technique used was single-patch in 21.6% (108), double-patch in 25.8% (128), and modified single-patch (Wilcox) in 52.5% (260) of patients. The follow-up time was 37.79+/-46.70 (range, 0-198) months. A total of 64 patients (12.9%) had arrhythmias while in the intensive care unit; pacemaker was implanted in 12 patients. A total of 78 patients (15.7%) were treated for pulmonary hypertensive crisis. The early morbidity and mortality in the postoperative first month were calculated as 38% and 10%, and the late morbidity and mortality (>1 month) were calculated as 13.1% and 1.9%, respectively. The rate of reoperation in our cohort was 8.9%. CONCLUSION: Although the early morbidity and mortality are low in AVSD operations, the rate of reoperations for left AV valve insufficiency are still high. Although Down syndrome is not a risk factor for early mortality, the co-morbid factors, such as longer postoperative mechanical ventilator or inotropic support, lead to higher risk for morbidity. The frequency of pulmonary hypertension and consequent complications are also high. PMID- 30297582 TI - Modeling the burden of cardiovascular disease in Turkey. AB - OBJECTIVE: This study aims to estimate the current and future burden of cardiovascular diseases (CVD) in Turkey. METHODS: A burden-of-disease model was developed that included inputs on population growth, prevalence, and incidence of ischemic disease (IHD) and cerebrovascular disease (CeVD), prevalence of modifiable risk factors, mortality rates, and relationship between risk factors and IHD/CeVD. Direct costs to the public health-care system and indirect costs from lost production due to premature mortality, hospitalizations, disability, and absenteeism were considered. RESULTS: We estimated that in 2016, 3.4 million Turkish adults were living with CVD, including 2.5 million affected by IHD, and 0.9 million by CeVD. This prevalence is projected to increase to 5.4 million by 2035. The economic burden of CVD was estimated at US$10.2 billion in 2016, projected to increase twofold to US$19.4 billion by 2035. CONCLUSION: Our study confirms that the current burden of CVD is significant, and that it is projected to increase at a steep rate over the next two decades. This growing burden of disease will likely create significant pressure on the public health-care system in the form of direct health-care costs, as well as on society in the form of lost productivity. PMID- 30297583 TI - Tips for management of arrhythmias in endocrine disorders from an European Heart Rhythm Association position paper. AB - In endocrine diseases, hormonal changes, electrolyte abnormalities, and the deterioration of heart structure can lead to various arrhythmias. In diabetic patients, hypoglycemia, hyperglycemia, and hypokalemia can trigger arrhythmias, and diabetic cardiomyopathy can also cause electrical and structural remodeling to form substrates for arrhythmias. The risk of atrial fibrillation (AF) increases in hyperthyroidism; however, the prevalence of ventricular arrhythmias in hypothyroidism is higher. Besides AF and ventricular tachycardias, bradycardias and atrioventricular blocks can also be seen in pheochromocytoma due to the desensitization of adrenergic cardiovascular receptors. The correction of metabolic and electrolyte disturbances in patients with adrenal cortex disease should be the main approach in the prevention and treatment of arrhythmias. Early initiation of treatment in patients with acromegaly seems to decrease the development of cardiac remodeling and ventricular arrhythmia. Early and late after depolarizations due to hypercalcemia in hyperparathyroidism can lead to life-threatening ventricular arrhythmias. This elegant position paper provides important recommendations regarding prevention and treatment of arrhythmias for specific endocrine disorders.

PMID- 30297596 TI - microRNA-29a inhibits cardiac fibrosis in Sprague-Dawley rats by downregulating the expression of DNMT3A. AB - OBJECTIVE: This study aims to investigate the effect of miR-29a targeting the regulation of DNMT3A on the development of cardiac fibrosis in Sprague-Dawley (SD) rats. METHODS: In vivo experiment: SD rats were randomly divided into model and control groups. The cardiac and left ventricular indices in each group were calculated. The pathological changes of the myocardium were observed. The expression levels of miR-29a, CollA1, alpha-SMA, and DNMT3A in the myocardium of each group were detected. In vitro experiment: The cardiac fibroblasts (CFs) of SD rats were isolated from the myocardial tissue of SD rats and cultured. The miR 29a mimics, inhibitors, DNMT3A-siRNA, and control-siRNA were transfected into CFs. The expression levels of miR-29a, DNMT3A, CollA1, and alpha-SMA were detected, and the proliferation of CFs after transfection was observed. RESULTS: The heart weight index of the rats in the model group increased significantly compared with that in the control group. Obvious collagen deposition was observed in the myocardial tissue of the model group. The expression levels of CollA1, alpha-SMA, and DNMT3A in the model group were significantly higher than those in the control group (p<0.05). CONCLUSION: miR-29a reduced the activation and proliferation of CFs to improve cardiac fibrosis probably by the downregulation of DNMT3A. PMID- 30297597 TI - Predictive value of baseline C-reactive protein for periprocedural myocardial infraction of higher risk stratifications: A retrospective cohort clinical study. AB - OBJECTIVE: It is controversial whether preprocedural elevated high sensitivity C reactive protein (CRP) could increase the incidence of periprocedural myocardial infraction (PMI) of higher risk stratifications. The primary aim of this study was to evaluate whether preoperative elevated CRP level was related to the incidence of PMI in patients who underwent percutaneous coronary intervention (PCI). METHODS: A total of 4,426 patients [66 y (59, 75); 72.3% males] with normal preprocedural cardiac enzymes were prospectively divided into two groups; the elevated CRP group was defined as CRP >3 mg/L, which was approximately 30.4% of the patients. The relationship between CRP and the incidence of PMI was established by multivariate logistic regression analysis, and multivariate linear regression analysis was used to assess the correlation between CRP and the severity of myocardial injury. RESULTS: The incidence rates were similar between the two groups with periprocedural myocardial minor necrosis (34.23% versus 32.74%, p=0.607), but significantly differed based on the 2007 (defined as cardiac enzymes >3-fold elevations), 31.25% in high CRP group versus 26.25% in low group [odds ratio (OR) 1.19; p=0.046] and the 2012 universal PMI (defined as cardiac enzymes >5-fold elevations with at least one clinical evidence, such as chest pain, ECG changes or imaging diagnosis of heart ischemia), 19.79% versus 15.35% (OR 1.26, p=0.023); besides, the PMI ratios increased in line with the elevation of CRP (p=0.006 for the 2007 and p=0.011 for the 2012 universal PMI). However, no significant linear relationship was found between CRP and high sensitivity cardiac troponin I peak post-PCI. CONCLUSION: Elevated baseline CRP was an independent risk factor for the incidence of the 2007 and the 2012 universal PMI rather than minor necrosis. However, CRP may not correlate with the severity of minor myocardial necrosis in patients with PMI. PMID- 30297598 TI - Do Individuals in Old Age Prepare for the Risk of Long-Term Care? Results of A Population-Based Survey in Germany. AB - The aim of the present study was to identify specific actions and financial precautions undertaken by individuals in preparation for their long-term care needs, as well as to determine the correlates of these actions. A population based survey of the German population aged 65 years and above (n = 1006) was used. Individuals were asked whether they have undertaken financial preparations for their long-term care needs (no; yes). With respect to specific actions, individuals were asked whether they (no; yes): (i) Had obtained information (e.g., from doctor, internet, care support center, care facility), (ii) had modified their home (e.g., installed a stair lift), and (iii) had moved (e.g., old-age housing, care in relatives' homes). In total, 30.4% had undertaken financial preparations for their long-term care needs. With respect to the specific actions undertaken, 6.5% had obtained information, 4.8% modified their home, and 7.3% had moved. The outcome measure, 'had modified home', was positively associated with lower age, West Germany, and lower self-rated health. The outcome measure, 'had moved', was positively associated with being female, and higher education. The outcome measure, 'financial preparations for long-term care needs', was positively associated with lower age, West Germany, higher education, being born in Germany, and private health insurance. It is alarming that only around one in three individuals aged 65 and older had undertaken financial preparations for long-term care needs, and that far fewer individuals had undertaken other actions to prepare for their long-term care needs. The provision of timely information regarding the risk of long-term care, as well as its associated costs, may assist in sustaining the satisfaction of long-term care recipients. It may also help to reduce the risk of long-term care for individuals in old age. PMID- 30297599 TI - The Identification of the Factors Related to Household Food Insecurity among Indigenous People (Orang Asli) in Peninsular Malaysia under Traditional Food Systems. AB - Over the course of 16 years, a high percentage of Orang Asli (OA) households in Malaysia has been found to be burdened with food insecurity. Therefore, a study was conducted to improve the understanding of the challenges faced by the OA in Peninsular Malaysia to achieve food security under traditional food systems. In this study, in-depth interview sessions, which were assisted by an interview protocol, were conducted with 61 OA women from nine villages that were selected purposefully across three states (Kelantan, Pahang, and Perak) in Peninsular Malaysia. Furthermore, thematic analysis was performed during data analysis. As a result, four themes were identified, namely (i) the failure in agriculture (sub themes: threats from wild animals and insufficient land supply), (ii) ineffectiveness of traditional food-seeking activities (sub-themes: exhausting, tiring, dangerous, and time-consuming journey for food-seeking activities, depletion of natural commodities, reduced demands of natural commodities, and lack of equipment), (iii) weather (sub-themes: rainy and dry seasons), and (iv) water issues (subthemes: continuity of water supply and cleanliness of water). The identified modifiable factors of this issue should be incorporated into future schemes of food security intervention in order to efficiently manage the food shortage among the OA. PMID- 30297601 TI - A Novel Wind Speed Estimation Based on the Integration of an Artificial Neural Network and a Particle Filter Using BeiDou GEO Reflectometry. AB - Oceanographic remote sensing, which is based on the sensitivity of reflected signals from the Global Navigation Satellite Systems (GNSS), so-called GNSS Reflectometry (GNSS-R), is very useful for the observation of ocean wind speed. Wind speed estimation over the ocean is the core factor in maritime transportation management and the study of climate change. The main concept of the GNSS-R technique is using the different times between the reflected and the direct signals to measure the wind speed and wind direction. Accordingly, this research proposes a novel technique for wind speed estimation involving the integration of an artificial neural network and the particle filter based on a theoretical model. Moreover, particle swarm optimization was applied to find the optimal weight and bias of the artificial neural network, in order to improve the accuracy of the estimation result. The observation dataset of the reflected signal information from BeiDou Geostationary Earth Orbit (GEO) satellite number 4 was used as an input for the estimation model. The data consisted of two phases with I and Q components. Two periods of BeiDou data were selected, the first period was from 3 to 8 August 2013 and the second period was from 12 to 14 August 2013, which corresponded to events from the typhoon Utor. The in situ wind speed measurement collected from the buoy station was used to validate the results. A coastal experiment was conducted at the Yangjiang site located in the South China Sea. The results show the ability of the proposed technique to estimate wind speed with a root mean square error of approximately 1.9 m/s. PMID- 30297600 TI - Zinc Inhibits Expression of Androgen Receptor to Suppress Growth of Prostate Cancer Cells. AB - The prostate gland contains a high level of intracellular zinc, which is dramatically diminished during prostate cancer (PCa) development. Owing to the unclear role of zinc in this process, therapeutic applications using zinc are limited. This study aimed to clarify the role of zinc and its underlying mechanism in the growth of PCa. ZnCl2 suppressed the proliferation of androgen receptor (AR)-retaining PCa cells, whereas it did not affect AR-deficient PCa cells. In LNCaP and TRAMP-C2 cells, zinc downregulated the expression of AR in a dose- and time-dependent fashion. Zinc-mediated AR suppression accordingly inhibited the androgen-mediated transactivation and expression of the androgen target, prostate specific antigen (PSA). This phenomenon resulted from facilitated protein degradation, not transcriptional control. In studies using mice bearing TRAMP-C2 subcutaneous tumors, the intraperitoneal injection of zinc significantly reduced tumor size. Analyses of both xenograft tumors and normal prostates showed reduced expression of AR and increased cell death. Considering the significant loss of intracellular zinc and the dominant growth-modulating role of AR during PCa development, loss of zinc may be a critical step in the transformation of normal cells to cancer cells. This study provides the underlying mechanism by which zinc functions as a PCa suppressor, and forms the foundation for developing zinc-mediated therapeutics for PCa.

AB - End stage renal disease (ESRD) is characterized by complex metabolic abnormalities, yet the clinical relevance of specific biomarkers remains unclear. The development of multiplex diagnostic platforms is creating opportunities to develop novel diagnostic and therapeutic approaches. SOMAscan is an innovative multiplex proteomic platform which can measure >1300 proteins. In the present study, we performed SOMAscan analysis of plasma samples and validated the measurements by comparison with selected biomarkers. We compared concentrations of SOMAscan-measured prostate specific antigen (PSA) between males and females, and validated SOMAscan concentrations of fibroblast growth factor 23 (FGF23), FGF receptor 1 (FGFR1), and FGFR4 using Enzyme-Linked immunosorbent assay (ELISA). The median (25th and 75th percentile) SOMAscan PSA level in males and females was 4304.7 (1815.4 to 7259.5) and 547.8 (521.8 to 993.4) relative fluorescence units (p = 0.002), respectively, suggesting biological plausibility. Pearson correlation between SOMAscan and ELISA was high for FGF23 (R = 0.95, p < 0.001) and FGFR4 (R = 0.69, p < 0.001), indicating significant positive correlation, while a weak correlation was found for FGFR1 (R = 0.13, p = 0.16). In conclusion, there is a good to near-perfect correlation between SOMAscan and standard immunoassays for FGF23 and FGFR4, but not for FGFR1. This technology may be useful to simultaneously measure a large number of plasma proteins in ESRD, and identify clinically important prognostic markers to predict outcomes.

AB - The impacts of free-roaming canids (domestic and wild) on public health have long been a concern in Australian Indigenous communities. We investigated the prevalence of zoonotic helminth diseases in dogs and sympatric dingoes, and used radio telemetry to measure their spatial overlap, in an Aboriginal community in the Wet Tropics of Australia. Samples collected from dingoes and dogs showed high levels of infection with the zoonotic hookworm, Ancylostoma caninum. Dingoes were also positive for A. ceylanicum infection (11.4%), but dogs were infection free. Whipworm, Trichuris vulpis, infection was far more prevalent in necropsies of domestic dogs (78.6%) than dingoes (3.7%). Dogs were free from Dirofilaria immitis infection, while dingoes recorded 46.2% infection. Eleven dingoes and seven free-roaming domestic dogs were fitted with Global Positioning System collars and tracked over an extended period. Dingo home-ranges almost completely overlapped those of the domestic dogs. However, dingoes and dogs did not utilise the same area at the same time, and dogs may have avoided dingoes. This spatial overlap in resource use presents an opportunity for the indirect spill-over and spill-back of parasites between dogs and dingoes. Tracking and camera traps showed that the community rubbish tip and animal carcasses were areas of concentrated activity for dogs and dingoes.

AB - Two easily accessible, natural occurring triterpenoids, betulinic and ursolic acid, were used as starting materials for the synthesis of novel cytotoxic agents. A set of 28 ethylenediamine-spacered carboxamides was prepared holding an additional substituent connected to the ethylenediamine group. The compounds were screened in SRB assays to evaluate their cytotoxic activity employing several human tumor cell lines. Betulinic acid-derived carboxamides 17-30 showed significantly higher cytotoxicity than their ursolic acid analogs 3-16. In particular, compounds 25 and 26 were highly cytotoxic, as indicated by EC50 values lower than 1 MUM. PMID- 30297605 TI - Music-Based Therapeutic Interventions for People with Dementia: A Mini-Review. AB - The growing population of people with dementia worldwide calls attention to the burdens associated with age-related decline that affects physiology, psychological and cognitive status, and social/emotional wellbeing. The current standards in geriatric care recommend non-pharmacological approaches to these challenges, including safe approaches to managing pain and stress, enhancing symptom relief, and fostering independent lifestyles with the highest quality of life possible. The purpose of this article is to provide definitions of music based interventions, music therapy applications and clinician qualifications, as well as an umbrella mini-review of meta-analyses regarding music-based interventions for individuals with dementia. Our findings indicate that most descriptions of music therapy protocols in the research lack sufficient detail to enable researchers to compare and replicate studies, and clinicians to apply techniques. Definitions of music therapy and music-based interventions are inconsistent, and practitioners vary in their professional training and preparation for implementing music-based clinical strategies. We recommend that future researchers provide thorough descriptions of music therapy and music-based interventions in their protocols. PMID- 30297606 TI - Energy Efficient Hybrid Routing Protocol Based on the Artificial Fish Swarm Algorithm and Ant Colony Optimisation for WSNs. AB - Wireless Sensor Networks (WSNs) are a particular type of distributed self-managed network with limited energy supply and communication ability. The most significant challenge of a routing protocol is the energy consumption and the extension of the network lifetime. Many energy-efficient routing algorithms were inspired by the development of Ant Colony Optimisation (ACO). However, due to the inborn defects, ACO-based routing algorithms have a slow convergence behaviour and are prone to premature, stagnation phenomenon, which hinders further route discovery, especially in a large-scale network. This paper proposes a hybrid routing algorithm by combining the Artificial Fish Swarm Algorithm (AFSA) and ACO to address these issues. We utilise AFSA to perform the initial route discovery in order to find feasible routes quickly. In the route discovery algorithm, we present a hybrid algorithm by combining the crowd factor in AFSA and the pseudo random route select strategy in ACO. Furthermore, this paper presents an improved pheromone update method by considering energy levels and path length. Simulation results demonstrate that the proposed algorithm avoids the routing algorithm falling into local optimisation and stagnation, whilst speeding up the routing convergence, which is more prominent in a large-scale network. Furthermore, simulation evaluation reports that the proposed algorithm exhibits a significant improvement in terms of network lifetime.

AB - We investigated the association between body composition and changes in glucose metabolism following laparoscopic sleeve gastrectomy (LSG) in obese Japanese patients. Thirty-two Class III obese patients were assessed before LSG and 3, 6, and 12 months postoperatively. Variables including fat mass (FM), % body fat (%FM), total and skeletal muscle mass (MM), the ratio of lower extremity MM to body weight (BW) (L/W), and the ratio of upper extremity MM to BW (U/W) were measured while using bioelectrical impedance analysis (BIA). LSG significantly decreased BW, FM, and %FM in all time periods observed after surgery with concomitant improvements in metabolic markers. MM was decreased at three months but maintained from 3-12 months post-surgery. Importantly, %MM, U/W, and the L/W ratio increased after LSG. Furthermore, change in FM was positively correlated with change in BW 12 months after LSG, whereas changes in %MM were negatively correlated with fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c). Finally, multivariable stepwise regression analyses showed that changes in % total MM was an independent determinant of FPG and change in % skeletal MM was a significant independent determinant of HbA1c in Class III obese Japanese patients after LSG.

AB - Nowadays, there is an increasing number of cameras placed on mobile devices connected to the Internet. Since these cameras acquire and process sensitive and vulnerable data in applications such as surveillance or monitoring, security is essential to avoid cyberattacks. However, cameras on mobile devices have constraints in size, computation and power consumption, so that lightweight security techniques should be considered. Camera identification techniques guarantee the origin of the data. Among the camera identification techniques, Physically Unclonable Functions (PUFs) allow generating unique, distinctive and unpredictable identifiers from the hardware of a device. PUFs are also very suitable to obfuscate secret keys (by binding them to the hardware of the device) and generate random sequences (employed as nonces). In this work, we propose a trusted camera based on PUFs and standard cryptographic algorithms. In addition, a protocol is proposed to protect the communication with the trusted camera, which satisfies authentication, confidentiality, integrity and freshness in the data communication. This is particularly interesting to carry out camera control actions and firmware updates. PUFs from Static Random Access Memories (SRAMs) are selected because cameras typically include SRAMs in its hardware. Therefore, additional hardware is not required and security techniques can be implemented at low cost. Experimental results are shown to prove how the proposed solution can be implemented with the SRAM of commercial Bluetooth Low Energy (BLE) chips included in the communication module of the camera. A proof of concept shows that the proposed solution can be implemented in low-cost cameras.

AB - Bacteria of the family Rhodobacteraceae are widespread in marine environments and known to colonize surfaces, such as those of e.g., oysters and shells. The marine bacterium Labrenzia sp. 011 is here investigated and it was found to produce two cyclopropane-containing medium-chain fatty acids (1, 2), which inhibit the growth of a range of bacteria and fungi, most effectively that of a causative agent of Roseovarius oyster disease (ROD), Pseudoroseovarius crassostreae DSM 16950. Additionally, compound 2 acts as a potent partial, beta-arrestin-biased agonist at the medium-chain fatty acid-activated orphan G-protein coupled receptor GPR84, which is highly expressed on immune cells. The genome of Labrenzia sp. 011 was sequenced and bioinformatically compared with those of other Labrenzia spp. This analysis revealed several cyclopropane fatty acid synthases (CFAS) conserved in all Labrenzia strains analyzed and a putative gene cluster encoding for two distinct CFASs is proposed as the biosynthetic origin of 1 and 2. PMID- 30297610 TI - Identification of Anti-Melanogenesis Constituents from Morus alba L. Leaves. AB - The individual parts of Morus alba L. including root bark, branches, leaves, and fruits are used as a cosmetic ingredient in many Asian countries. This study identified several anti-melanogenesis constituents in a 70% ethanol extract of M. alba leaves. The ethyl acetate fraction of the initial ethanol extract decreased the activity of tyrosinase, a key enzyme in the synthetic pathway of melanin. Twelve compounds were isolated from this fraction and their structures were identified based on spectroscopic spectra. Then, the authors investigated the anti-melanogenesis effects of the isolated compounds in B16-F10 mouse melanoma cells. Compounds 3 and 8 significantly inhibited not only melanin production but also intracellular tyrosinase activity in alpha-melanocyte-stimulating-hormone (alpha-MSH)-induced B16-F10 cells in a dose-dependent manner. These same compounds also inhibited melanogenesis-related protein expression such as microphthalmia-associated transcription factor (MITF), tyrosinase, and tyrosinase related protein-1 (TRP-1). Compound 3 modulated the cAMP-responsive element binding protein (CREB) and p38 signaling pathways in alpha-MSH-activated B16-F10 melanoma cells, which resulted in the anti-melanogenesis effects. These results suggest that compound 3, isolated from M. alba leaves, could be used to inhibit melanin production via the regulation of melanogenesis-related protein expression. PMID- 30297611 TI - The Issue of Burnout and Work Satisfaction in Younger GPs-A Cluster Analysis Utilizing the HaMEdSi Study. AB - The shortage of general practitioners (GPs) in Germany has become a relevant problem. Therefore, it is important to find the determinants that make primary care more attractive, and which support GPs remaining in practice. Our aim in this exploratory study was to search for relevant GP subgroups and their characteristics in order to find starting points for improvements or interventions. We attempted a comprehensive survey of all GPs in the German region of Siegen-Wittgenstein with about 280,000 inhabitants. There were 158 GPs in the total population; 85 of these (53.8%) took part in the study. There were 64 male GPs (75.3%) in our sample. The mean age of the participants was 53.5 years (SD 8.93). The questionnaire was composed of demographic questions, questions regarding future perspectives, the Motivation for Medical Education Questionnaire (MoME-Q), the Maslach Burnout Inventory (MBI), and the Work Satisfaction Questionnaire. K-means cluster analyses were used for subgrouping. A 2-cluster solution had good statistical quality criteria. Cluster 1 was characterised by elderly GPs who more frequently had a resident physician in their practices. These GPs had low burnout scores and high work satisfaction scores. Cluster 2 consisted of younger GPs who less frequently had a resident in their practices. They had average burnout scores according to published norms and lower work satisfaction scores. There seems to be an age cohort effect regarding burnout and work satisfaction. Having a resident physician seems to be protective. Interventions should be designed for younger GPs, especially members of generation Y, to reduce burnout and improve work satisfaction. PMID- 30297614 TI - Positioning Performance of BDS Observation of the Crustal Movement Observation Network of China and Its Potential Application on Crustal Deformation. AB - The Crustal Movement Observation Network of China (CMONOC) has begun receiving BeiDou Navigation Satellite System (BDS) observations since 2015, and accumulated more than 2.5 years of data. BDS observations has been widely applied in many fields, and long-term continuous data provide a new strategy for the study of crustal deformation in China. This paper focuses on the evaluation of BDS positioning performance and its potential application on crustal deformation in CMONOC. According to the comparative analysis on multipath delay (MPD) and signal to noise ratio (SNR) between BDS and GPS data, the data quality of BDS is at the same level with GPS measurements in COMONC. The spatial distribution of BDS positioning accuracy evaluated as the root mean square (RMS) of daily residual position time series on horizontal component is latitude-dependent, declining with the increasing of station latitude, while the vertical one is randomly distributed in China. The mean RMS of BDS position residual time series is 7 mm and 22 mm on horizontal and vertical components, respectively, and annual periodicity in position time series can be identified by BDS data. In view of the accuracy of BDS positioning, there are no systematic differences between GPS and BDS results. Based on time series analysis with data volume being 2.5 years, the noise characteristics of BDS daily position time series is time-correlated and corresponding noise is white plus flicker noise model, and the derived mean RMS of the BDS velocities is 1.2, 1.5, and 4.1 mm/year on north, east, and up components, respectively. The imperfect performance of BDS positioning relative to GPS is likely attributed to the relatively low accuracy of BDS ephemeris, and the sparse amount of MEO satellites distribution in the BDS constellation. It is expectable to study crustal deformation in CMONOC by BDS with the gradual maturity of its constellation and the accumulation of observations. PMID- 30297613 TI - Nb2O5 and Ti-Doped Nb2O5 Charge Trapping Nano-Layers Applied in Flash Memory. AB - High-k material charge trapping nano-layers in flash memory applications have faster program/erase speeds and better data retention because of larger conduction band offsets and higher dielectric constants. In addition, Ti-doped high-k materials can improve memory device performance, such as leakage current reduction, k-value enhancement, and breakdown voltage increase. In this study, the structural and electrical properties of different annealing temperatures on the Nb2O5 and Ti-doped Nb2O5(TiNb2O7) materials used as charge-trapping nano layers in metal-oxide-high k-oxide-semiconductor (MOHOS)-type memory were investigated using X-ray diffraction (XRD) and atomic force microscopy (AFM). Analysis of the C-V hysteresis curve shows that the flat-band shift (?VFB) window of the TiNb2O7 charge-trapping nano-layer in a memory device can reach as high as 6.06 V. The larger memory window of the TiNb2O7 nano-layer is because of a better electrical and structural performance, compared to the Nb2O5 nano-layer. PMID- 30297612 TI - A Comprehensive Review of Arsenic Exposure and Risk from Rice and a Risk Assessment among a Cohort of Adolescents in Kunming, China. AB - Inorganic arsenic (iAs) is carcinogenic and highly concentrated in rice. Dietary exposure to iAs is concerning among adolescents due to their developmental stage and iAs's long-latency effects. This paper aimed to assess iAs exposure from rice and related lifetime cancer risks (LCR) among adolescents in Kunming, China. A comprehensive literature review of iAs levels in rice and LCR in humans was also conducted. Average daily consumption of rice (ADC) was estimated from 267 adolescents (15-18 years). Rice samples obtained from 6 markets were analyzed for iAs concentration (AC). Estimated daily intake (EDI) of iAs was calculated using ADC, AC, and average body weight (BW). Lifetime Cancer Risk (LCR) was calculated using EDI and U.S. EPA derived iAs oral slope factor. The AC was 0.058 mg/kg and the average BW and ADC were 67.5 kg and 410 g/day for males and 55.5 kg and 337 g/day for females. The EDI and LCR were 3.52 * 10-4 mg/kg-BW/day and 5.28 * 10-4 for both males and females, with LCR 5 times above the U.S. LCR upper limit of 1.0 * 10-4. While the AC was below the Chinese maximum contaminant level of 0.2 mg/kg, study results indicated that Kunming adolescents may be at increased risk for iAs-related cancers. PMID- 30297616 TI - Interaction of Clostridium perfringens Iota Toxin and Lipolysis-Stimulated Lipoprotein Receptor (LSR). AB - Iota toxin produced by Clostridium perfringens is a binary, actin ADP ribosylating toxin that is organized into the enzymatically active component Ia and the binding component Ib. Lipolysis-stimulated lipoprotein receptor (LSR) has been identified as a cellular receptor of Ib. Here, we investigated the functional interaction between Ib and LSR, where siRNA for LSR blocked the toxin mediated cytotoxicity and the binding of Ib. The addition of Ib to LSR-green fluorescence protein (GFP)-transfected cells at 4 degrees C resulted in colocalization with LSR and Ib on the cell surface. Upon transfer of the cells from 4 degrees C to 37 degrees C, LSR and Ib were internalized and observed in cytoplasmic vesicles. When the cells were incubated with Ib at 37 degrees C and fractionated using the Triton-insoluble membrane, Ib oligomer was localized in insoluble factions that fulfilled the criteria of lipid rafts, and LSR was clustered in lipid rafts. To examine the interaction between N-terminal extracellular region of LSR and Ib, we constructed a series of LSR N-terminal deletions. Ten amino acids residues can be deleted from this end without any reduction of Ib binding. However, deletion of 15 N-terminal residues drastically reduces its ability to bind Ib. These results demonstrate that Ib binds to the LSR N-terminal 10 to 15 residues and endocytoses into trafficking endosomes together with LSR. PMID- 30297615 TI - Gut Microbiota's Relationship with Liver Disease and Role in Hepatoprotection by Dietary Natural Products and Probiotics. AB - A variety of dietary natural products have shown hepatoprotective effects. Increasing evidence has also demonstrated that gut microorganisms play an important role in the hepatoprotection contributed by natural products. Gut dysbiosis could increase permeability of the gut barrier, resulting in translocated bacteria and leaked gut-derived products, which can reach the liver through the portal vein and might lead to increased oxidative stress and inflammation, thereby threatening liver health. Targeting gut microbiota modulation represents a promising strategy for hepatoprotection. Many natural products could protect the liver from various injuries or mitigate hepatic disorders by reverting gut dysbiosis, improving intestinal permeability, altering the primary bile acid, and inhibiting hepatic fatty acid accumulation. The mechanisms underlying their beneficial effects also include reducing oxidative stress, suppressing inflammation, attenuating fibrosis, and decreasing apoptosis. This review discusses the hepatoprotective effects of dietary natural products via modulating the gut microbiota, mainly focusing on the mechanisms of action.

Leaves and Tentative Identification of Bioactive Constituents through LC-QTOF-MS/MS and Molecular Docking Approach. AB - The objective of the present study was to investigate the antiradical and xanthine oxidase inhibitory effects of Averrhoa bilimbi leaves. Hence, crude methanolic leaves extract and its resultant fractions, namely hexane, chloroform, and n-butanol were evaluated for 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging effect and xanthine oxidase inhibitory activity. The active constituents were tentatively identified through LC-QTOF-MS/MS and molecular docking approaches. The n-butanol fraction of A. bilimbi crude methanolic leaves extract displayed significant DPPH radical scavenging effect with IC50 (4.14 +/- 0.21 MUg/mL) (p < 0.05), as well as xanthine oxidase inhibitory activity with IC50 (64.84 +/- 3.93 MUg/mL) (p < 0.05). Afzelechin 3-O-alpha-l-rhamnopyranoside and cucumerin A were tentatively identified as possible metabolites that contribute to the antioxidant activity of the n-butanol fraction. PMID- 30297617 TI - Pain in Mucopolysaccharidoses: Analysis of the Problem and Possible Treatments. AB - Mucopolysaccharidosis (MPS) are a group of lysosomal storage disorders that are caused by the deficiency of enzymes involving in the catabolism of glycosaminoglycan (GAGs). GAGs incompletely degraded accumulate in many sites, damaging tissues and cells, leading to a variety of clinical manifestations. Many of these manifestations are painful, but few data are available in the literature concerning the prevalence, etiology, and pathogenesis of pain in children with MPS. This review, through the analysis of the data available the in literature, underscores the relevant prevalence of pain in MPSs' children, provides the instruments to discern the etiopathogenesis of the disease and of pain, illustrates the available molecules for the management of pain and the possible advantages of non-pharmacological pain therapy in MPSs' patients. PMID- 30297619 TI - Fermentation: A Boon for Production of Bioactive Compounds by Processing of Food Industries Wastes (By-Products). AB - A large number of by-products or wastes are produced worldwide through various food industries. These wastes cause a serious disposable problem with the environment. So, now a day's different approaches are used for alternative use of these wastes because these by-products are an excellent source of various bioactive components such as polyphenols, flavonoids, caffeine, carotenoids, creatine, and polysaccharides etc. which are beneficial for human health. Furthermore, the composition of these wastes depends on the source or type of waste. Approximately half of the waste is lignocellulosic in nature produced from food processing industries. The dissimilar types of waste produced by food industries can be fortified by various processes. Fermentation is one of the oldest approaches and there are three types of fermentation processes that are carried out such as solid state, submerged and liquid fermentation used for product transformation into value added products through microorganisms. Selections of the fermentation process are product specific. Moreover, various studies were performed to obtain or fortified different bioactive compounds that are present in food industries by-products or wastes. Therefore, the current review article discussed various sources, composition and nutritive value (especially bioactive compounds) of these wastes and their management or augmentation of value-added products through fermentation. PMID- 30297622 TI - Interest Forwarding in Named Data Networking Using Reinforcement Learning. AB - In-network caching is one of the key features of information-centric networks (ICN), where forwarding entities in a network are equipped with memory with which they can temporarily store contents and satisfy en route requests. Exploiting in network caching, therefore, presents the challenge of efficiently coordinating the forwarding of requests with the volatile cache states at the routers. In this paper, we address information-centric networks and consider in-network caching specifically for Named Data Networking (NDN) architectures. Our proposal departs from the forwarding algorithms which primarily use links that have been selected by the routing protocol for probing and forwarding. We propose a novel adaptive forwarding strategy using reinforcement learning with the random neural network (NDNFS-RLRNN), which leverages the routing information and actively seeks new delivery paths in a controlled way. Our simulations show that NDNFS-RLRNN achieves better delivery performance than a strategy that uses fixed paths from the routing layer and a more efficient performance than a strategy that retrieves contents from the nearest caches by flooding requests. PMID- 30297620 TI - Spatiotemporal Changes in PM2.5 and Their Relationships with Land-Use and People in Hangzhou. AB - Increases in the extent and level of air pollution in Chinese cities have become a major concern of the public and burden on the government. While ample literature has focused on the status, changes and causes of air pollution (particularly on PM2.5 and PM10), significantly less is known on their effects on people. In this study we used Hangzhou, China, as our testbed to assess the direct impact of PM2.5 on youth populations that are more vulnerable to pollution. We used the ground monitoring data of air quality and Aerosol optical thickness (AOT) product from the Moderate Resolution Imaging Spectroradiometer (MODIS) for the spatiotemporal changes of PM2.5 by season in 2015. We further explored these distributions with land cover, population density and schools (kindergarten, primary school and middle school) to explore the potential impacts in seeking potential mitigation solutions. We found that the seasonal variation of PM2.5 concentration was winter > spring > autumn > summer. In Hangzhou, the percentage of land area exposed to PM2.5 > 50 ug m-3 accounted for 59.86% in winter, 56.62% in spring, 40.44% in autumn and 0% in summer, whereas these figures for PM2.5 of <35 ug m-3 were 70.01%, 5.28%, 5.17%, 4.16% in summer, winter, autumn and spring, respectively. As for land cover, forest experienced PM2.5 of 35-50 ug m-3 (i.e., lower than those of other cover types), likely due to the potential filtering and absorption function of the forests. More importantly, a quantitative index based on population-weighted exposure level (pwel) indicated that only 9.06% of the population lived in areas that met the national air quality standards. Only 1.66% (14,055) of infants and juveniles lived in areas with PM2.5 of <35 ug m-3. Considering the legacy effects of PM2.5 over the long-term, we highly recommend improving the monitoring systems for both air quality and people (i.e., their health conditions), with special attention paid to infants and juveniles.

AB - In order to find a simple, generic, efficient separation method for 25R/S spirostanol saponin diastereomers, the liquid chromatographic retention behaviors of C12 carbonylation and C12 unsubstituted 25R/S-spirostanol saponin diastereomers on different stationary phases (C8, C18, C30 columns) and different mobile phases (MeOH-1% CH3COOH and CH3CN-1% CH3COOH) were investigated. A C30 column was firstly found to offer the highest efficiency for the separation of this kind of diastereomers than C8 and C18 columns. Meanwhile, the analysis results indicated that both CH3CN-1% CH3COOH and MeOH-1% CH3COOH eluate systems were selective for C12 unsubstituted 25R/S-spirostanol saponin diastereomers, while MeOH-1% CH3COOH possessed better selectivity for C12 carbonylation ones. Using the abovementioned analysis method, six pairs of 25R/S-spirostanol saponin diastereomers 1a-6a and 1b-6b from Yucca schidigera Roezl (Mojave) were isolated successfully by using HPLC on C30 column for the first time. Among them, three pairs were new ones, named as (25R)-Yucca spirostanoside E1 (1a), (25S)-Yucca spirostanoside E1 (1b), (25R)-Yucca spirostanoside E2 (2a), (25S)-Yucca spirostanoside E2 (2b), (25R)-Yucca spirostanoside E3 (3a), (25S)-Yucca spirostanoside E3 (3b), respectively. Moreover, 3a, 5a, 6a, 3b-6b showed strong inhibitory activities on the growth of SW620 cell lines with the IC50 values of 12.02-69.17 MUM.

AB - Synaptic plasticity has been considered a key mechanism underlying many brain functions including learning, memory, and drug addiction. An increase or decrease in synaptic activity of the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) complex mediates the phenomena as shown in the cellular models of synaptic plasticity, long-term potentiation (LTP), and depression (LTD). In particular, protein phosphorylation shares the spotlight in expressing the synaptic plasticity. This review summarizes the studies on phosphorylation of the AMPAR pore-forming subunits and auxiliary proteins including transmembrane AMPA receptor regulatory proteins (TARPs) and discusses its role in synaptic plasticity. PMID- 30297621 TI - Peroxidase Activity of Human Hemoproteins: Keeping the Fire under Control. AB - The heme in the active center of peroxidases reacts with hydrogen peroxide to form highly reactive intermediates, which then oxidize simple substances called peroxidase substrates. Human peroxidases can be divided into two groups: (1) True peroxidases are enzymes whose main function is to generate free radicals in the peroxidase cycle and (pseudo)hypohalous acids in the halogenation cycle. The major true peroxidases are myeloperoxidase, eosinophil peroxidase and lactoperoxidase. (2) Pseudo-peroxidases perform various important functions in the body, but under the influence of external conditions they can display peroxidase-like activity. As oxidative intermediates, these peroxidases produce not only active heme compounds, but also protein-based tyrosyl radicals. Hemoglobin, myoglobin, cytochrome c/cardiolipin complexes and cytoglobin are considered as pseudo-peroxidases. Reroxidases play an important role in innate immunity and in a number of physiologically important processes like apoptosis and cell signaling. Unfavorable excessive peroxidase activity is implicated in oxidative damage of cells and tissues, thereby initiating the variety of human diseases. Hence, regulation of peroxidase activity is of considerable importance. Since peroxidases differ in structure, properties and location, the mechanisms controlling peroxidase activity and the biological effects of peroxidase products are specific for each hemoprotein. This review summarizes the knowledge about the properties, activities, regulations and biological effects of true and pseudo peroxidases in order to better understand the mechanisms underlying beneficial and adverse effects of this class of enzymes. PMID- 30297625 TI - Silicon-Mediated Enhancement of Heavy Metal Tolerance in Rice at Different Growth Stages. AB - Silicon (Si) plays important roles in alleviating heavy metal stress in rice plants. Here we investigated the physiological response of rice at different growth stages under the silicon-induced mitigation of cadmium (Cd) and zinc (Zn) toxicity. Si treatment increased the dry weight of shoots and roots and reduced the Cd and Zn concentrations in roots, stems, leaves and grains. Under the stress of exposure to Cd and Zn, photosynthetic parameters including the chlorophyll content and chlorophyll fluorescence decreased, while the membrane permeability and malondialdehyde (MDA) increased. Catalase (CAT) and peroxidase (POD) activities increased under heavy metals stress, but superoxide dismutase (SOD) activities decreased. The magnitude of these Cd- and Zn-induced changes was mitigated by Si-addition at different growth stages. The available Cd concentration increased in the soil but significantly decreased in the shoots, which suggested that Si treatment prevents Cd accumulation through internal mechanisms by limiting Cd2+ uptake by the roots. Overall, the phenomena of Si mediated alleviation of Cd and excess Zn toxicity in two rice cultivars could be due to the limitation of metal uptake and transport, resulting in an improvement in cell membrane integrity, photosynthetic performance and anti-oxidative enzyme activities after Si treatment.

AB - Early maturity is one of the most important agronomical traits in potato breeding. To identify the DNA segment that codes for early maturity, a tetraploid potato segregation population of "Zhongshu 19" * "Zhongshu 3" was genetically analyzed, using a combination of high throughput simplified genome sequencing (2b RAD) and bulked segregant analysis (BSA). The DNA segment related to the early maturity trait was identified at the 3.7~4.2 Mb locus on the short arm of chromosome 5. Eight molecular markers were developed, of which five were closely linked to the early-maturity trait loci. Additionally, 42 simple sequence repeats (SSR) markers were constructed based on the reference sequence of Solanum tuberosum group Phureja DM1-3 516 R44 (DM). Using the TetraploidMap software, the linkage map of chromosome 5 was constructed with 50 markers. The total map length was 172 centiMorgan (cM), with an average genetic distance of 3.44 cM. Correlating molecular and phenotypic data of the segregating population, the mapped Quantitative Trait Loci (QTL) on the short arm of chromosome 5 contributed to 33.55% of the early-maturity phenotype. The early-maturity QTL was located at 84 cM, flanked by the SSR5-85-1 and SCAR5-8 markers. The QTL was fine-mapped to 471 kb. Using DNA sequence annotation, 34 genes were identified in this region, 12 of them with unknown function. Among the other 22 annotated genes, E3 ubiquitin ligase gene PUB14 could be related to maturity and regulation of tuber formation. The constructed QTL map is a useful basic tool for the cloning of early-maturity related genes in tetraploid potatoes.

AB - The aim of this study was to examine calf circumference in relation to cognitive frailty in community-dwelling older adults. Cross-sectional analysis was performed on the first-year baseline data of 1559 adults aged 70-84 years enrolled in the Korean Frailty and Aging Cohort Study. The final analysis included 1221 adults who were non-dependent in terms of instrumental activities of daily living, who underwent frailty and cognitive function assessments. Physical frailty was defined using the Fried Frailty Index. Cognitive impairment was defined as a score 1.5 standard deviations below the age-, sex- and education matched norms on any of four cognitive-function tests. The prevalence of cognitive frailty was 2.8% for men and 3.8% for women. After adjusting for potential confounders, in comparison to the "physically robust without cognitive impairment" group, the estimates of increased odds ratios (ORs) for low calf circumference (<32 cm) were much greater in the prefrail with cognitive impairment (OR 4.62, 95% confidence interval (CI): 2.02-10.61) and frail with cognitive impairment (OR 10.94, 95% CI: 2.87-41.68) groups in men but not in women. Low calf circumference was strongly related to cognitive frailty in men only, suggesting calf circumference can be used as an indicator of these outcomes.

AB - Ganoderma lucidum, a famous medicinal mushroom used worldwide, is a rich source of triterpenoids which, together with polysaccharides, are believed to be the main effective constituents of G. lucidum. With the increase of market demand, the wild resource is facing serious limitations, and the quality of cultivated fruiting bodies can be seriously affected by the availability of wood resources and by cultivation management practices. In the present study, we aimed to develop an alternative way to produce useful triterpenoids from G. lucidum. We cultured the strain using a two-stage liquid culture strategy and investigated the effects of nitrogen limitation, carbon supply, static culture volume and air supply in the static culture stage on the accumulation of five triterpenoids (GA P, GA-Q, GA-T, GA-S, GA-R). Our results showed that, under optimized condition, the total yield of the five triterpenoids reached 963 mg/L (as determined by HPLC). Among the five triterpenoids, GA-T accounted for about 75% of the total yield. Besides, a bioreactor suitable for fungal liquid static culture with a 10 L extensible plastic bag shaped culture unit was designed and in which the maximum total yield of the five GAs reached 856.8 mg/L, and the GAs content reached 5.99%. Our results demonstrate the potential of industrial application of G. lucidum culture for the production of triterpenoids, especially GA-T. Air supply significantly improved the accumulation of triterpenoids, and this will provide important clues to understand why more triterpenoids are produced in the mycelia mat under static liquid culture conditions.

AB - The rising prevalence of non-alcoholic fatty liver disease (NAFLD) parallels the global increase in the number of people diagnosed with obesity and metabolic syndrome. The gut-liver axis (GLA) plays an important role in the pathogenesis of NAFLD/non-alcoholic steatohepatitis (NASH). In this review, we discuss the clinical significance and underlying mechanisms of action of gut-derived secretory factors in NAFLD/NASH, focusing on recent human studies. Several studies have identified potential causal associations between gut-derived secretory factors and NAFLD/NASH, as well as the underlying mechanisms. The effects of gut-derived hormone-associated drugs, such as glucagon-like peptide-1 analog and recombinant variant of fibroblast growth factor 19, and other new treatment strategies for NAFLD/NASH have also been reported. A growing body of evidence highlights the role of GLA in the pathogenesis of NAFLD/NASH. Larger and longitudinal studies as well as translational research are expected to provide additional insights into the role of gut-derived secretory factors in the pathogenesis of NAFLD/NASH, possibly providing novel markers and therapeutic targets in patients with NAFLD/NASH. PMID- 30297628 TI - Prescribing Hemodialysis or Hemodiafiltration: When One Size Does Not Fit All the Proposal of a Personalized Approach Based on Comorbidity and Nutritional Status. AB - There is no simple way to prescribe hemodialysis. Changes in the dialysis population, improvements in dialysis techniques, and different attitudes towards the initiation of dialysis have influenced treatment goals and, consequently, dialysis prescription. However, in clinical practice prescription of dialysis still often follows a "one size fits all" rule, and there is no agreed distinction between treatment goals for the younger, lower-risk population, and for older, high comorbidity patients. In the younger dialysis population, efficiency is our main goal, as assessed by the demonstrated close relationship between depuration (tested by kinetic adequacy) and survival. In the ageing dialysis population, tolerance is probably a better objective: "good dialysis" should allow the patient to attain a stable metabolic balance with minimal dialysis-related morbidity. We would like therefore to open the discussion on a personalized approach to dialysis prescription, focused on efficiency in younger patients and on tolerance in older ones, based on life expectancy, comorbidity, residual kidney function, and nutritional status, with particular attention placed on elderly, high-comorbidity populations, such as the ones presently treated in most European centers. Prescription of dialysis includes reaching decisions on the following elements: dialysis modality (hemodialysis (HD) or hemodiafiltration (HDF)); type of membrane (permeability, surface); and the frequency and duration of sessions. Blood and dialysate flow, anticoagulation, and reinfusion (in HDF) are also briefly discussed. The approach described in this concept paper was developed considering the following items: nutritional markers and integrated scores (albumin, pre-albumin, cholesterol; body size, Body Mass Index (BMI), Malnutrition Inflammation Score (MIS), and Subjective Global Assessment (SGA)); life expectancy (age, comorbidity (Charlson Index), and dialysis vintage); kinetic goals (Kt/V, normalized protein catabolic rate (n PCR), calcium phosphate, parathyroid hormone (PTH), beta-2 microglobulin); technical aspects including vascular access (fistula versus catheter, degree of functionality); residual kidney function and weight gain; and dialysis tolerance (intradialytic hypotension, post-dialysis fatigue, and subjective evaluation of the effect of dialysis on quality of life). In the era of personalized medicine, we hope the approach described in this concept paper, which requires validation but has the merit of providing innovation, may be a first step towards raising attention on this issue and will be of help in guiding dialysis choices that exploit the extraordinary potential of the present dialysis "menu". PMID- 30297631 TI - Neuromodulation of Synaptic Transmission in the Main Olfactory Bulb. AB - A major step in our understanding of brain function is to determine how neural circuits are altered in their function by signaling molecules or neuromodulators. Neuromodulation is the neurochemical process that modifies the computations performed by a neuron or network based on changing the functional needs or behavioral state of the subject. These modulations have the effect of altering the responsivity to synaptic inputs. Early sensory processing areas, such as the main olfactory bulb, provide an accessible window for investigating how neuromodulation regulates the functional states of neural networks and influences how we process sensory information. Olfaction is an attractive model system in this regard because of its relative simplicity and because it links primary olfactory sensory neurons to higher olfactory and associational networks. Likewise, centrifugal fibers from higher order brain centers target neurons in the main olfactory bulb to regulate synaptic processing. The neuromodulatory systems that provide regulatory inputs and play important roles in olfactory sensory processing and behaviors include the endocannabinoid system, the dopaminergic system, the cholinergic system, the noradrenergic system and the serotonergic system. Here, we present a brief survey of neuromodulation of olfactory signals in the main olfactory bulb with an emphasis on the endocannabinoid system. PMID- 30297632 TI - Systematic Screening of Commonly Used Commercial Transfection Reagents towards Efficient Transfection of Single-Stranded Oligonucleotides. AB - Non-viral vector-mediated transfection is a core technique for in vitro screening of oligonucleotides. Despite the growing interests in the development of oliogonucleotide-based drug molecules in recent years, a comprehensive comparison of the transfection efficacy of commonly used commercial transfection reagents has not been reported. In this study, five commonly used transfection reagents, including Lipofectamine 3000, Lipofectamine 2000, Fugene, RNAiMAX and Lipofectin, were comprehensively analyzed in ten cell lines using a fluorescence imaging based transfection assay. Although the transfection efficacy and toxicity of transfection reagents varied depending on cell types, the toxicity of transfection reagents generally displayed a positive correlation with their transfection efficacy. According to our results, Lipofectamine 3000, Fugene and RNAiMAX showed high transfection efficacy, however, RNAiMAX may be a better option for majority of cells when lower toxicity is desired. The transfection efficacy of Lipofectamine 2000 was compromised by its high toxicity, which may adversely affect its application in most cells. We firmly believe that our findings may contribute to the future In vitro delivery and screening of single stranded therapeutic oligonucleotides such as antisense oligonucleotides, antimiRs, and DNAzymes. PMID- 30297633 TI - Effect of Differential Speed Rotation Technology on the Forming Uniformity in Flexible Rolling Process. AB - As the local forming non-uniform of the formed curved surface part with larger bending deformation is the one of common defects, the utilization ratio of metal plate greatly reduces due to this defect, and cost of production is also increasing. In this paper, the differential speed rotation technology of flexible rolling process was proposed firstly to solve this forming defect. The finite element model was established, the reason of the local forming non-uniform was discussed; the effect of differential speed rotation technology on the forming uniform was studied. The results show that: Flexible rolling is a process based on thickness reduction, in this forming process, the thickness reduces sharply near the back end of metal plate, the local forming non-uniform of formed curved surface part is caused during this process; the differential speed rotation technology is applied in flexible rolling, with increasing rotation speed difference between upper and lower roll set, the forming uniformity of the formed curved surface part is greatly improved. The results of numerical simulation are in agreement with the result of forming experiments. PMID- 30297635 TI - Pharmacokinetic Properties of Acetyl Tributyl Citrate, a Pharmaceutical Excipient. AB - Acetyl tributyl citrate (ATBC) is an (the Food and Drug Administration) FDA approved substance for use as a pharmaceutical excipient. It is used in pharmaceutical coating of solid oral dosage forms such as coated tablets or capsules. However, the information of ATBC on its pharmacokinetics is limited. The aim of this study is to investigate the pharmacokinetic properties of ATBC using liquid chromatography-tandem mass spectrometric (LC-MS/MS) analysis. ATBC was rapidly absorbed and eliminated and the bioavailability was 27.4% in rats. The results of metabolic stability tests revealed that metabolic clearance may have accounted for a considerable portion of the total clearance of ATBC. These pharmacokinetic data would be useful in studies investigating the safety and toxicity of ATBC. PMID- 30297634 TI - Opposite Regulation of CHOP and GRP78 and Synergistic Apoptosis Induction by Selenium Yeast and Fish Oil via AMPK Activation in Lung Adenocarcinoma Cells. AB - Selenium has been intensively studied for the use of cancer prevention and treatment. However, the clinical effects are still plausible. To enhance its efficacy, a combinational study of selenium yeast (SY) and fish oil (FO) was performed in A549, CL1-0, H1299, HCC827 lung adenocarcinoma (LADC) cells to investigate the enhancement in apoptosis induction and underlying mechanism. By sulforhodamine B staining, Western blot and flow cytometric assays, we found a synergism between SY and FO in growth inhibition and apoptosis induction of LADC cells. In contrast, the fetal lung fibroblast cells (MRC-5) were unsusceptible to this combination effect. FO synergized SY-induced apoptosis of A549 cells, accompanied with synergistic activation of AMP-activated protein kinase (AMPK) and reduction of Cyclooxygenase (COX)-2 and beta-catenin. Particularly, combining with FO not only enhanced the SY-elevated proapoptotic endoplasmic reticulum (ER) stress marker CCAAT/enhancer-binding protein homologous protein (CHOP), but also reduced the cytoprotective glucose regulated protein of molecular weight 78 kDa (GRP78). Consequently, the CHOP downstream targets such as phospho-JNK and death receptor 5 were also elevated, along with the cleavage of caspase-8, -3, and the ER stress-related caspase-4. Accordingly, inhibition of AMPK by compound C diminished the synergistic apoptosis induction, and elevated CHOP/GRP78 ratio by SY combined with FO. The AMPK-dependent synergism suggests the combination of SY and FO for chemoprevention and integrative treatment of LADC. PMID- 30297636 TI - Reduction of Real-Time Imaging of M1 Macrophage Chemotaxis toward Damaged Muscle Cells is PI3K-Dependent. AB - Macrophages migrate and invade into damaged muscle rapidly and are important for muscle repair and subsequent regeneration. The exact cellular and biological events that cause macrophage migration toward injured muscle are not completely understood. In this study, the effect of macrophage differentiation on the chemotactic capability to invade local damaged muscle was investigated using an in vitro model of muscle injury. We used C2C12 cell myoblasts and J774 cell macrophages, and the "killed-C2C12" cells were combined with live C2C12 cells as a partially damaged muscle model. The cultured J774 cells, with or without lipopolysaccharide (LPS), were treated with Ly294002 (Ly), which is an inhibitor of phosphoinositide 3-kinase (PI3K). In order to evaluate the polarization effect of LPS stimulation on J774 cells, expression of cell surface Toll-like receptor 4 (TLR4), CD11c and CCR2, and expression of F-actin intensity, were analyzed by flow cytometry. The real-time horizontal chemotaxis assay of J774 cells was tested using the TAXIScan device. The expressions of TLR4, CD11c, and F-actin intensity in LPS-treated cells were significantly higher than those in Ctrl cells. In LPS-treated cells, the chemotactic activity toward damaged muscle cells completely disappeared. Moreover, the reduced chemotaxis depended far more on directionality than velocity. However, Ly treatment reversed the reduced chemotactic activity of the LPS-treated cells. In addition, cell-adhesion and F actin intensity, but not CCR2 expression, in LPS-treated cells, was significantly reduced by Ly treatment. Taken together, our results suggest that the PI3K/Akt activation state drives migration behavior towards damaged muscle cells. PMID- 30297637 TI - Does Residential Green and Blue Space Promote Recovery in Psychotic Disorders? A Cross-Sectional Study in the Province of Utrecht, The Netherlands. AB - Mental health is reportedly influenced by the presence of green and blue space in residential areas, but scientific evidence of a relation to psychotic disorders is scant. We put two hypotheses to the test: first, compared to the general population, psychiatric patients live in neighborhoods with less green and blue space; second, the amount of green and blue space is negatively associated with the duration of hospital admission. The study population consisted of 623 patients with psychotic disorders who had been admitted to the psychiatric ward of an academic hospital in Utrecht, The Netherlands from 2008 to 2016. Recovery was measured by length of stay. Structured patient data was linked to socio economic status and the amount of green and blue space in the residential area. Associations were assessed by means of regression models controlling for confounding factors. Compared to the general population, psychiatric patients had a significantly lower amount of green space in their neighborhood. This result was not confirmed for blue space. Furthermore, no significant associations were found between green and blue space and the duration of hospital stay. In conclusion, previous studies focusing on other mental disorders, like anxiety or depression, found positive mental health effects of green and blue space in the neighborhood. We were not able to confirm significant effects among our study population on duration of admission, however. Future research focusing on psychotic patients could investigate the influence of exposure to green and blue space on other influences and outcomes on mental health. PMID- 30297638 TI - Metabolic Stability and Metabolite Characterization of Capilliposide B and Capilliposide C by LC-QTRAP-MS/MS. AB - Capilliposide B (LC-B) and Capilliposide C (LC-C), two new triterpenoid saponins extracted from Lysimachia capillipes Hemsl, exhibit potential anticancer activity both in vitro and in vivo. However, their metabolic process remains unclear. In this study, the metabolic stability of LC-B, LC-C, and Capilliposide A (LC-A, a bioactive metabolite of LC-B and LC-C) was investigated in human, rat, and mouse liver microsomes, respectively. Thereafter, their metabolites were identified and characterized after oral administration in mice. As a result, species difference was found in the metabolic stability of LC-B and LC-C. All three compounds of interest were stable in human and rat liver microsomes, but LC-B and LC-C significantly degraded in mouse liver microsomes. The metabolic instability of LC B and LC-C was mainly caused by esterolysis. Moreover, 19 metabolites were identified and characterized in mouse biological matrices. LC-B and LC-C mainly underwent deglycosylation and esterolysis, accompanied by dehydration, dehydrogenation, and hydroxylation as minor metabolic reactions. Finally, the metabolic pathway of LC-B and LC-C in mice was proposed. Our results updated the preclinical metabolism and disposition process of LC-B and LC-C, which provided additional information for better understanding efficacy and safety. PMID- 30297639 TI - Automatic Rectification of the Hybrid Stereo Vision System. AB - By combining the advantages of 360-degree field of view cameras and the high resolution of conventional cameras, the hybrid stereo vision system could be widely used in surveillance. As the relative position of the two cameras is not constant over time, its automatic rectification is highly desirable when adopting a hybrid stereo vision system for practical use. In this work, we provide a method for rectifying the dynamic hybrid stereo vision system automatically. A perspective projection model is proposed to reduce the computation complexity of the hybrid stereoscopic 3D reconstruction. The rectification transformation is calculated by solving a nonlinear constrained optimization problem for a given set of corresponding point pairs. The experimental results demonstrate the accuracy and effectiveness of the proposed method. PMID- 30297642 TI - Low Praziquantel Treatment Coverage for Schistosoma mansoni in Mayuge District, Uganda, Due to the Absence of Treatment Opportunities, Rather Than Systematic Non Compliance. AB - The World Health Organization (WHO) recommends praziquantel mass drug administration (MDA) to control schistosomiasis in endemic regions. We aimed to quantify recent and lifetime praziquantel coverage, and reasons for non treatment, at an individual level to guide policy recommendations to help Uganda reach WHO goals. Cross-sectional household surveys (n = 681) encompassing 3208 individuals (adults and children) were conducted in 2017 in Bugoto A and B, Mayuge District, Uganda. Participants were asked if they had received praziquantel during the recent MDA (October 2016) and whether they had ever received praziquantel in their lifetime. A multivariate logistic regression analysis with socio-economic and individual characteristics as covariates was used to determine factors associated with praziquantel uptake. In the MDA eligible population (>=5 years of age), the most recent MDA coverage was 48.8%. Across individuals' lifetimes, 31.8% of eligible and 49.5% of the entire population reported having never taken praziquantel. Factors that improved individuals' odds of taking praziquantel included school enrolment, residence in Bugoto B and increasing years of village-residency. Not being offered (49.2%) and being away during treatment (21.4%) were the most frequent reasons for not taking the 2016 praziquantel MDA. Contrary to expectations, chronically-untreated individuals were rarely systematic non-compliers, but more commonly not offered treatment. PMID- 30297641 TI - Poly-Gamma-Glutamic Acid (gamma-PGA)-Based Encapsulation of Adenovirus to Evade Neutralizing Antibodies. AB - In recent years, there has been an increasing interest in oncolytic adenoviral vectors as an alternative anticancer therapy. The induction of an immune response can be considered as a major limitation of this kind of application. Significant research efforts have been focused on the development of biodegradable polymer poly-gamma-glutamic acid (gamma-PGA)-based nanoparticles used as a vector for effective and safe anticancer therapy, owing to their controlled and sustained release properties, low toxicity, as well as biocompatibility with tissue and cells. This study aimed to introduce a specific destructive and antibody blind polymer-coated viral vector into cancer cells using gamma-PGA and chitosan (CH). Adenovirus was successfully encapsulated into the biopolymer particles with an encapsulation efficiency of 92% and particle size of 485 nm using the ionic gelation method. Therapeutic agents or nanoparticles (NPs) that carry therapeutics can be directed specifically to cancerous cells by decorating their surfaces using targeting ligands. Moreover, in vitro neutralizing antibody response against viral capsid proteins can be somewhat reduced by encapsulating adenovirus into gamma-PGA-CH NPs, as only 3.1% of the encapsulated adenovirus was detected by anti-adenovirus antibodies in the presented work compared to naked adenoviruses. The results obtained and the unique characteristics of the polymer established in this research could provide a reference for the coating and controlled release of viral vectors used in anticancer therapy. PMID- 30297640 TI - Transcriptome Sequencing Reveals the Differentially Expressed lncRNAs and mRNAs Involved in Cryoinjuries in Frozen-Thawed Giant Panda (Ailuropoda melanoleuca) Sperm. AB - Sperm cryopreservation and artificial insemination are important methods for giant panda breeding and preservation of extant genetic diversity. Lower conception rates limit the use of artificial insemination with frozen-thawed giant panda sperm, due to the lack of understanding of the cryodamaging or cryoinjuring mechanisms in cryopreservation. Long non-coding RNAs (lncRNAs) are involved in regulating spermatogenesis. However, their roles during cryopreservation remain largely unexplored. Therefore, this study aimed to identify differentially expressed lncRNAs and mRNAs associated with cryodamage or freeze tolerance in frozen-thawed sperm through high throughput sequencing. A total of 61.05 Gb clean reads and 22,774 lncRNA transcripts were obtained. From the sequencing results, 1477 significantly up-regulated and 1,396 significantly down-regulated lncRNA transcripts from fresh and frozen-thawed sperm of giant panda were identified. GO and KEGG showed that the significantly dysregulated lncRNAs and mRNAs were mainly involved in regulating responses to cold stress and apoptosis, such as the integral component of membrane, calcium transport, and various signaling pathways including PI3K-Akt, p53 and cAMP. Our work is the first systematic profiling of lncRNA and mRNA in fresh and frozen-thawed giant panda sperm, and provides valuableinsights into the potential mechanism of cryodamage in sperm. PMID- 30297644 TI - New Insights into Development of Transglutaminase 2 Inhibitors as Pharmaceutical Lead Compounds. AB - Transglutaminase 2 (EC 2.3.2.13; TG2 or TGase 2) plays important roles in the pathogenesis of many diseases, including cancers, neurodegeneration, and inflammatory disorders. Under normal conditions, however, mice lacking TGase 2 exhibit no obvious abnormal phenotype. TGase 2 expression is induced by chemical, physical, and viral stresses through tissue-protective signaling pathways. After stress dissipates, expression is normalized by feedback mechanisms. Dysregulation of TGase 2 expression under pathologic conditions, however, can potentiate pathogenesis and aggravate disease severity. Consistent with this, TGase 2 knockout mice exhibit reversal of disease phenotypes in neurodegenerative and chronic inflammatory disease models. Accordingly, TGase 2 is considered to be a potential therapeutic target. Based on structure-activity relationship assays performed over the past few decades, TGase 2 inhibitors have been developed that target the enzyme's active site, but clinically applicable inhibitors are not yet available. The recently described the small molecule GK921, which lacks a group that can react with the active site of TGase 2, and efficiently inhibits the enzyme's activity. Mechanistic studies revealed that GK921 binds at an allosteric binding site in the N-terminus of TGase 2 (amino acids (a.a.) 81-116), triggering a conformational change that inactivates the enzyme. Because the binding site of GK921 overlaps with the p53-binding site of TGase 2, the drug induces apoptosis in renal cell carcinoma by stabilizing p53. In this review, we discuss the possibility of developing TGase 2 inhibitors that target the allosteric binding site of TGase 2. PMID- 30297643 TI - Characterization of a Novel N-Acylhomoserine Lactonase RmmL from Ruegeria mobilis YJ3. AB - Gram-negative bacteria utilize N-acylhomoserine lactones (AHLs) as quorum sensing (QS) signaling molecules for intercellular communication. Cell-to-cell communication depends on cell population density, and AHL-dependent QS is related to the production of multiple genes including virulence factors. Quorum quenching (QQ), signal inactivation by enzymatic degradation, is a potential strategy for attenuating QS regulated bacterial infections. Both Gram-positive and -negative bacteria have QQ enzymes that can degrade AHLs. In our previous study, strain Ruegeria mobilis YJ3, isolated from healthy shrimp, showed strong AHLs degradative activity. In the current study, an AHL lactonase (designated RmmL) was cloned and characterized from Ruegeria mobilis YJ3. Amino acid sequence analysis showed that RmmL has a conserved "HXHXDH" motif and clusters together with lactonase AidC that belongs to the metallo-beta-lactamase superfamily. Recombinant RmmL could degrade either short- or long-chain AHLs in vitro. High performance liquid chromatography analysis indicated that RmmL works as an AHL lactonase catalyzing AHL ring-opening by hydrolyzing lactones. Furthermore, RmmL can reduce the production of pyocyanin by Pseudomonas aeruginosa PAO1, while for the violacein and the extracellular protease activities by Chromobacterium violaceum CV026 and Vibrio anguillarum VIB72, no significant reduction was observed. This study suggests that RmmL might be used as a therapeutic agent in aquaculture. PMID- 30297645 TI - Preparation of Self-supporting Bagasse Cellulose Nanofibrils Hydrogels Induced by Zinc Ions. AB - Cellulose hydrogels are often prepared from native cellulose through a direct cellulose dissolution approach that often involves tedious process and solvent recovery problems. A self-supporting cellulose hydrogel was prepared by gelation of the TEMPO-oxidized bagasse cellulose nanofibrils (CNF) triggered by strong crosslinking between carboxylate groups and Zn2+. TEMPO process was used to generate negatively charged carboxylate groups on CNF surface to provide a high binding capability to Zn2+. Three TEMPO-oxidized CNFs of different carboxylate contents were prepared and characterized. TEM and AFM microscopes suggested that the sizes of CNFs were fined down and carboxylated cellulose nanofibrils (TOCNFs) of 5-10 nm wide, 200-500 nm long, and carboxylate contents 0.73-1.29 mmol/g were obtained. The final structures and compressive strength of hydrogels were primarily influenced by interfibril Zn2+-carboxylate interactions, following the order of TOCNFs concentration > content of carboxylate groups > concentration of zinc ions. A CO2 sensitive self-supporting cellulose hydrogel was developed as a colorimetric indicator of food spoilage for intelligent food packaging applications. PMID- 30297646 TI - A Comprehensive Study on the Biological Activity of Elderberry Extract and Cyanidin 3-O-Glucoside and Their Interactions with Membranes and Human Serum Albumin. AB - In our research we used the extract from dietary supplement of elderberry (EE) and its dominant anthocyanin-cyanidin 3-O-glucoside (Cy 3-gluc). By interacting with a model membrane that reflects the main lipid composition of tumor membranes, the extract components, including Cy 3-gluc, caused an increase in packing order, mainly in the hydrophilic region of the membrane. It can thus be stated that EE caused a rigidifying effect, which is fundamental for understanding its anticancer and antioxidant activity. This study represents the first attempt to unravel the mechanism of interaction of elderberry extract with membranes. The results of the interaction with human serum albumin (HSA) proved that the studied substance quenches the fluorescence of HSA through a static mechanism in which the main interaction forces are Van der Waals and hydrogen bonding. The antioxidant activity of EE and Cy 3-gluc on liposomal membranes, antiradical properties and ability to inhibited the activity of the enzymes cyclooxygenase-1 and cyclooxygenase-2 were also demonstrated. Moreover, the anticancer activity of EE and Cy 3-gluc on human breast adenocarcinoma cell line were investigated. In addition, EE also exhibited the ability to form lipid aggregates in the form of liposomal capsules that can be applied as carriers of active biological substances, and the highest efficacy of EE encapsulation was obtained for multilayered liposome formulations. PMID- 30297647 TI - Enhanced Pulsatile Growth Hormone Secretion and Altered Metabolic Hormones by in Vivo Hexarelin Treatment in Streptozotocin-Induced Diabetic Rats. AB - Significant growth hormone (GH) reductions have been reported in diabetic animal models with disturbed metabolic balance coinciding with GH deficiency. Therefore, enhanced GH secretion may have beneficial effects in controlling diabetes. Thus, we aim to investigate the effect of hexarelin, a synthetic GH secretagogue (GHS), on GH secretion in streptozotocin (STZ, 65 mg/kg)-induced diabetic rats. Daily hexarelin (100 MUg/kg) treatment was performed for two weeks in four-week-long STZ-diabetic and vehicle control rats. Pulsatile GH secretion in STZ-rats was significantly reduced in total, pulsatile, basal, and mass of GH secretion per burst. In addition, impaired GH secretion was followed by an increase in fasting level free fatty acids (FFAs) and a decrease in insulin-like growth factor 1 (IGF 1) compared to control rats. After hexarelin treatment, pulsatile GH secretion in STZ-rats was significantly increased in total, pulsatile, and basal, but not in the mass GH secretion per burst, compared to STZ-rats without hexarelin treatment. However, there was no significant elevation in GH secretion in the hexarelin-treated control group. In addition, hexarelin-treated STZ-rats showed a significant decrease in fasting level FFAs, whereas suppression of fasting level for IGF-1 was maintained. These results suggest that STZ-induced diabetic rats have impaired pulsatile GH secretion, causing increased FFAs and decreased IGF-1 levels in circulation. Hexarelin injections for two weeks is able to normalize impaired pulsatile GH secretion with normal fasting levels of FFAs, but fails to recover IGF-1 levels. PMID- 30297649 TI - A Novel Fault Location Method for a Cross-Bonded HV Cable System Based on Sheath Current Monitoring. AB - In order to improve the practice in the operation and maintenance of high voltage (HV) cables, this paper proposes a fault location method based on the monitoring of cable sheath currents for use in cross-bonded HV cable systems. This method first analyzes the power-frequency component of the sheath current, which can be acquired at cable terminals and cable link boxes, using a Fast Fourier Transform (FFT). The cable segment where a fault occurs can be localized by the phase difference between the sheath currents at the two ends of the cable segment, because current would flow in the opposite direction towards the two ends of the cable segment with fault. Conversely, in other healthy cable segments of the same circuit, sheath currents would flow in the same direction. The exact fault position can then be located via electromagnetic time reversal (EMTR) analysis of the fault transients of the sheath current. The sheath currents have been simulated and analyzed by assuming a single-phase short-circuit fault to occur in every cable segment of a selected cross-bonded high voltage cable circuit. The sheath current monitoring system has been implemented in a 110 kV cable circuit in China. Results indicate that the proposed method is feasible and effective in location of HV cable short circuit faults.

AB - Endocrine disorders are becoming an increasing problem in both human and veterinary medicine. In recent years, more and more horses worldwide have been suffering from equine metabolic syndrome (EMS). This metabolic disorder is characterized by pathological obesity, hyperinsulinaemia, hyperglycaemia and insulin resistance. Although metabolic disorders, including diabetes, have been extensively studied, there are still no data on the molecular effects of EMS in horses. Thus, the aim of this study was to evaluate apoptosis, oxidative stress, autophagy and microRNA (miR) expression in multipotent intestinal epithelial stem cells (IECs) and pancreatic islets (PIs) isolated post mortem form healthy and EMS diagnosed horses. Our group was the first to describe how EMS affects IEC and PI aging and senescence. First, we evaluated isolation and culture protocol for these cells and subsequently established their metabolic status in vitro. Both IECs and PIs isolated from EMS horses were characterized by increased apoptosis and senescence. Moreover, they accumulated elevated levels of reactive oxygen species (ROS). Here we have observed that autophagy/mitophagy may be a protective mechanism which allows those cells to maintain their physiological function, clear protein aggregates and remove damaged organelles. Furthermore, it may play a crucial role in reducing endoplasmic reticulum (ER) stress. This protective mechanism may help to overcome the harmful effects of ROS and provide building blocks for protein and ATP synthesis.

Twenty to thirty percent of EAC overexpress the human epidermal growth factor receptor 2 (Her2), a transmembrane receptor tyrosine kinase promoting cell growth and proliferation. Patients with Her2 overexpressing breast and gastroesophageal cancer may benefit from Her2 inhibitors. Therapy resistance, however, is well documented. Since autophagy, a lysosome-dependent catabolic process, is implicated in cancer resistance mechanisms, we tested whether autophagy modulation influences Her2 inhibitor sensitivity in EAC. Her2 positive OE19 EAC cells showed an induction in autophagic flux upon treatment with the small molecule Her2 inhibitor Lapatinib. Newly generated Lapatinib resistant OE19 (OE19 LR) cells showed increased basal autophagic flux compared to parental OE19 (OE19 P) cells. Based on these results, we tested if combining Lapatinib with autophagy inhibitors might be beneficial. OE19 P showed significantly reduced cell viability upon double treatment, while OE19 LR were already sensitive to autophagy inhibition alone. Additionally, Her2 status and autophagy marker expression (LC3B and p62) were investigated in a treatment-naive EAC patient cohort (n = 112) using immunohistochemistry. Here, no significant correlation between Her2 status and expression of LC3B and p62 was found. Our data show that resistance to Her2-directed therapy is associated with a higher basal autophagy level, which is not per se associated with Her2 status. Therefore, we propose that autophagy may contribute to acquired resistance to Her2-targeted therapy in EAC, and that combining Her2 and autophagy inhibition might be beneficial for EAC patients.

AB - In this analysis, a method for construction of forest canopy three-dimensional (3D) models from terrestrial LiDAR was used for assessing the influence of structural changes on reflectance for an even-aged forest in Belgium. The necessary data were extracted by the developed method, as well as it was registered the adjacent point-clouds, and the canopy elements were classified. Based on a voxelized approach, leaf area index (LAI) and the vertical distribution of leaf area density (LAD) of the forest canopy were derived. Canopy radiation interactions were simulated in a ray tracing environment, giving suitable illumination properties and optical attributes of the different canopy elements. Canopy structure was modified in terms of LAI and LAD for hyperspectral measurements. It was found that the effect of a 10% increase in LAI on NIR reflectance can be equal to change caused by translating 50% of leaf area from top to lower layers. As presented, changes in structure did affect vegetation indices associated with LAI and chlorophyll content. Overall, the work demonstrated the ability of terrestrial LiDAR for detailed canopy assessments and revealed the high complexity of the relationship between vertical LAD and reflectance.

AB - Fractionation of the bioactive extract of a culture of the marine derived actinomycete Streptomyces cyaneofuscatus M-157 led to the isolation of the known 3-hydroxyquinaldic acid (4), its amide (5) and three new derivatives (1-3) containing different amino acid residues. The structures of the new molecules (1 3), including their absolute configuration, were determined by the analysis of their ESI-TOF MS and one-dimensional (1D) and two-dimensional (2D) NMR spectra and advanced Marfey's analysis of their hydrolyzation products. Compound 3 spontaneously dimerized in solution to give the disulfide derivative 6. Unfortunately, none of the new compounds isolated confirmed the antimicrobial activity found in the bacterial extract, perhaps indicating that such antibacterial activity might be due to presence in the extract at the trace level of larger bioactive 3-hydroxyquinaldic acid derivatives from which compounds 1-3 are biosynthetic precursors. Cytotoxicity tests confirmed the moderate and weak IC50 values of 15.6 and 51.5 uM for compounds 5 and 1, respectively. PMID- 30297653 TI - New Method for Simultaneous Determination of Microcystins and Cylindrospermopsin in Vegetable Matrices by SPE-UPLC-MS/MS. AB - Cyanotoxins are a large group of noxious metabolites with different chemical structure and mechanisms of action, with a worldwide distribution, producing effects in animals, humans, and crop plants. When cyanotoxin-contaminated waters are used for the irrigation of edible vegetables, humans can be in contact with these toxins through the food chain. In this work, a method for the simultaneous detection of Microcystin-LR (MC-LR), Microcystin-RR (MC-RR), Microcystin-YR (MC YR), and Cylindrospermopsin (CYN) in lettuce has been optimized and validated, using a dual solid phase extraction (SPE) system for toxin extraction and ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) for analysis. Results showed linear ranges (5-50 ng g-1 f.w.), low values for limit of detection (LOD) (0.06-0.42 ng g-1 f.w.), and limit of quantification (LOQ) (0.16-0.91 ng g-1 f.w.), acceptable recoveries (41-93%), and %RSDIP values for the four toxins. The method proved to be robust for the three variables tested. Finally, it was successfully applied to detect these cyanotoxins in edible vegetables exposed to cyanobacterial extracts under laboratory conditions, and it could be useful for monitoring these toxins in edible vegetables for better exposure estimation in terms of risk assessment. PMID- 30297655 TI - The C-Reactive Protein/Albumin Ratio as a Predictor of Mortality in Critically Ill Patients. AB - The C-reactive protein (CRP)/albumin ratio has recently emerged as a marker for poor prognosis or mortality across various patient groups. This study aimed to identify the association between CRP/albumin ratio and 28-day mortality and predict the accuracy of CRP/albumin ratio for 28-day mortality in medical intensive care unit (ICU) patients. This was a retrospective cohort study of 875 patients. We evaluated the prognostic value of CRP/albumin ratio to predict mortality at 28 days after ICU admission, using Cox proportional hazard model and Kaplan-Meier survival analysis. The 28-day mortality was 28.0%. In the univariate analysis, the Acute Physiology and Chronic Health Evaluation II (APACHE II) score (p < 0.001), CRP level (p = 0.045), albumin level (p < 0.001), and CRP/albumin ratio (p = 0.032) were related to 28-day mortality. The area under the receiver operating characteristic (ROC) curve (the area under the ROC curves (AUC)) of CRP/albumin ratio was higher than that of CRP for mortality (0.594 vs. 0.567, p < 0.001). The cut-off point for CRP/albumin ratio for mortality was 34.3. On Cox proportional-hazard regression analysis, APACHE II score (hazards ratio (HR) = 1.05, 95% confidence interval (CI) = 1.04-1.07, p < 0.001) and CRP/albumin ratio (HR = 1.68, 95% CI = 1.27-2.21, p < 0.001 for high CRP/albumin ratio) were independent predictors of 28-day mortality. Higher CRP/albumin ratio was associated with increased mortality in critically ill patients. PMID- 30297654 TI - Construction of Multiple Switchable Sensors and Logic Gates Based on Carboxylated Multi-Walled Carbon Nanotubes/Poly(N,N-Diethylacrylamide). AB - In this work, binary hydrogel films based on carboxylated multi-walled carbon nanotubes/poly(N,N-diethylacrylamide) (c-MWCNTs/PDEA) were successfully polymerized and assembled on a glassy carbon (GC) electrode surface. The electroactive drug probes matrine and sophoridine in solution showed reversible thermal-, salt-, methanol- and pH-responsive switchable cyclic voltammetric (CV) behaviors at the film electrodes. The control experiments showed that the pH responsive property of the system could be ascribed to the drug components of the solutions, whereas the thermal-, salt- and methanol-sensitive behaviors were attributed to the PDEA constituent of the films. The CV signals particularly, of matrine and sophoridine were significantly amplified by the electrocatalysis of c MWCNTs in the films at 1.02 V and 0.91 V, respectively. Moreover, the addition of esterase, urease, ethyl butyrate, and urea to the solution also changed the pH of the system, and produced similar CV peaks as with dilution by HCl or NaOH. Based on these experiments, a 6-input/5-output logic gate system and 2-to-1 encoder were successfully constructed. The present system may lead to the development of novel types of molecular computing systems. PMID- 30297656 TI - Salmon Fillet Intake Led to Higher Serum Triacylglycerol in Obese Zucker Fa/Fa Rats But Not in Normolipidemic Long-Evans Rats. AB - The triacylglycerol lowering effect of fatty fish and fish oils is well recognized, however we recently showed that salmon intake resulted in higher serum triacylglycerol concentration in obese Zucker fa/fa rats. Since effects of salmon fillet have never before been studied in rats, the objective of this study was to compare effects of salmon intake on serum lipids in hyperlipidemic obese rats with normolipidemic lean rats. Zucker fa/fa rats and Long-Evans rats were fed diets with 25% protein from baked salmon fillet and 75% protein from casein, or casein as sole protein source (control group) for four weeks. Serum triacylglycerol concentration was higher, and cholesterol and apolipoproteinB-100 concentrations were lower in Zucker fa/fa rats fed Baked Salmon Diet compared to Zucker fa/fa rats fed Control Diet, with no differences in serum triacylglycerol, cholesterol and apolipoproteinB-100 between Long-Evans rats fed Baked Salmon Diet or Control Diet. Serum triacylglycerol fatty acid composition showed greater similarities to dietary fatty acids in Zucker fa/fa rats than in Long-Evans rats. To conclude, intake of baked salmon fillet resulted in higher serum triacylglycerol concentration and lower serum cholesterol concentration in hyperlipidemic obese Zucker fa/fa rats but did not affect serum lipids in normolipidemic lean Long-Evans rats. PMID- 30297658 TI - Characteristics of Graphene Oxide Films Reduced by Using an Atmospheric Plasma System. AB - The chemical oxidation method can be used to mass-produce graphene oxides (GOs) from highly oriented pyrolytic graphite. However, numerous oxygen-containing functional groups (hydroxyl, epoxy, carbonyl, etc.) exist in typical GO surfaces, resulting in serious electrical losses. Hence, GO must be processed into reduced graphene oxide (rGO) by the removal of most of the oxygen-containing functional groups. This research concentrates on the reduction efficiency of GO films that are manufactured using atmospheric-pressure and continuous plasma irradiation. Before and after sessions of plasma irradiation with various irradiation times, shelters, and working distances, the surface, physical, and electrical characteristics of homemade GO and rGO films are measured and analyzed. Experimental results showed that the sheet resistance values of rGO films with silicon or quartz shelters were markedly lower than those of GO films because the rGO films were mostly deprived of oxygen-containing functional groups. The lowest sheet resistance value and the largest carbon-to-oxygen ratio of typical rGO films were approximately 90 Omega/sq and 1.522, respectively. The intensity of the C-O bond peak in typical rGO films was significantly lower than that in GO films. Moreover, the intensity of the C-C bond peak in typical rGO films was considerably higher than that in GO films. PMID- 30297657 TI - Effects of Ag Additive in Low Temperature CO Detection with In2O3 Based Gas Sensors. AB - Nanocomposites In2O3/Ag obtained by ultraviolet (UV) photoreduction and impregnation methods were studied as materials for CO sensors operating in the temperature range 25-250 degrees C. Nanocrystalline In2O3 and In2O3/Ag nanocomposites were characterized by X-ray diffraction (XRD), single-point Brunauer-Emmet-Teller (BET) method, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and high angle annular dark field scanning transmission electron microscopy (HAADF-STEM) with energy dispersive X ray (EDX) mapping. The active surface sites were investigated using Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), electron paramagnetic resonance (EPR) spectroscopy and thermo-programmed reduction with hydrogen (TPR-H2) method. Sensor measurements in the presence of 15 ppm CO demonstrated that UV treatment leads to a complete loss of In2O3 sensor sensitivity, while In2O3/Ag-UV nanocomposite synthesized by UV photoreduction demonstrates an increased sensor signal to CO at T < 200 degrees C. The observed high sensor response of the In2O3/Ag-UV nanocomposite at room temperature may be due to the realization of an additional mechanism of CO oxidation with participation of surface hydroxyl groups associated via hydrogen bonds. PMID- 30297659 TI - An Evolutionary Game-Theoretic Approach for Assessing Privacy Protection in mHealth Systems. AB - With the rapid deployment of mobile technologies and their applications in the healthcare domain, privacy concerns have emerged as one of the most critical issues. Traditional technical and organizational approaches used to address privacy issues ignore economic factors, which are increasingly important in the investment strategy of those responsible for ensuring privacy protection. Taking the mHealth system as the context, this article builds an evolutionary game to model three types of entities (including system providers, hospitals and governments) under the conditions of incomplete information and bounded rationality. Given that the various participating entities are often unable to accurately estimate their own profits or costs, we propose a quantified approach to analyzing the optimal strategy of privacy investment and regulation. Numerical examples are provided for illustration and simulation purpose. Based upon these examples, several countermeasures and suggestions for privacy protection are proposed. Our analytical results show that governmental regulation and auditing has a significant impact on the strategic choice of the other two entities involved. In addition, the strategic choices of system providers and hospitals are not only correlated with profits and investment costs, but they are also significantly affected by free riding. If the profit growth coefficients increase to a critical level, mHealth system providers and hospitals will invest in privacy protection even without the imposition of regulations. However, the critical level is dependent on the values of the parameters (variables) in each case of investment and profits. PMID- 30297660 TI - Factors Associated with Early Mortality in Critically Ill Patients Following the Initiation of Continuous Renal Replacement Therapy. AB - Continuous renal replacement therapy (CRRT) is an important modality to support critically ill patients, and the need for CRRT treatment has been increasing. However, CRRT management is costly, and the associated resources are limited. Thus, it remains challenging to identify patients that are likely to have a poor outcome, despite active treatment with CRRT. We sought to elucidate the factors associated with early mortality after CRRT initiation. We analyzed 240 patients who initiated CRRT at an academic medical center between September 2016 and January 2018. We compared baseline characteristics between patients who died within seven days of initiating CRRT (early mortality), and those that survived more than seven days beyond the initiation of CRRT. Of the patients assessed, 130 (54.2%) died within seven days of CRRT initiation. Multivariate logistic regression models revealed that low mean arterial pressure, low arterial pH, and high Sequential Organ Failure Assessment score before CRRT initiation were significantly associated with increased early mortality in patients requiring CRRT. In conclusion, the mortality within seven days following CRRT initiation was very high in this study. We identified several factors that are associated with early mortality in patients undergoing CRRT, which may be useful in predicting early outcomes, despite active treatment with CRRT. PMID- 30297661 TI - Chemical Components and Biological Activities of the Genus Phyllanthus: A Review of the Recent Literature. AB - Medicinal plants have served humans since prehistoric times to treat various ailments. Both developed and underdeveloped countries rely on traditional systems of medication using natural sources from plants. Phyllanthus is one of the largest genus in the family Phyllanthaceae, comprising over 700 well known species cosmopolitan in distribution mainly in the tropics and subtropics. Phyllanthus species are being in constant used in traditional medications to cure an array of human diseases (constipation, inhalation related, arthritis, loss of appetite, injuries, conjunctivitis, diarrhoea, running nose, common cold, malaria, blennorrhagia, colic, diabetes mellitus, dysentery, indigestion, fever, gout, gonorrheal diseases of males and females, skin itching, jaundice, hepatic disorders, leucorrhea, vaginitis, menstrual irregularities, obesity, stomach pains, and tumors), confectionaries, food industry, and in some pesticides. Phyllanthus species are rich in diversity of phytochemicals e.g., tannins, terpenes, alkaloids, glycosidic compounds, saponins, and flavones etc. More in depth studies are a direly needed to identify more compounds with specific cellular functions to treat various ailments. PMID- 30297662 TI - Human Dendritic Cells: Ontogeny and Their Subsets in Health and Disease. AB - Dendritic cells (DCs) are a type of cells derived from bone marrow that represent 1% or less of the total hematopoietic cells of any lymphoid organ or of the total cell count of the blood or epithelia. Dendritic cells comprise a heterogeneous population of cells localized in different tissues where they act as sentinels continuously capturing antigens to present them to T cells. Dendritic cells are uniquely capable of attracting and activating naive CD4+ and CD8+ T cells to initiate and modulate primary immune responses. They have the ability to coordinate tolerance or immunity depending on their activation status, which is why they are also considered as the orchestrating cells of the immune response. The purpose of this review is to provide a general overview of the current knowledge on ontogeny and subsets of human dendritic cells as well as their function and different biological roles. PMID- 30297664 TI - Copaifera langsdorffii Novel Putative Long Non-Coding RNAs: Interspecies Conservation Analysis in Adaptive Response to Different Biomes. AB - Long non-coding RNAs (lncRNAs) are involved in multiple regulatory pathways and its versatile form of action has disclosed a new layer in gene regulation. LncRNAs have their expression levels modulated during plant development, and in response to stresses with tissue-specific functions. In this study, we analyzed lncRNA from leaf samples collected from the legume Copaifera langsdorffii Desf. (copaiba) present in two divergent ecosystems: Cerrado (CER; Ecological Station of Botanical Garden in Brasilia, Brazil) and Atlantic Rain Forest (ARF; Rio de Janeiro, Brazil). We identified 8020 novel lncRNAs, and they were compared to seven Fabaceae genomes and transcriptomes, to which 1747 and 2194 copaiba lncRNAs were mapped, respectively, to at least one species. The secondary structures of the lncRNAs that were conserved and differentially expressed between the populations were predicted using in silico methods. A few selected lncRNA were confirmed by RT-qPCR in the samples from both biomes; Additionally, the analysis of the lncRNA sequences predicted that some might act as microRNA (miRNA) targets or decoys. The emerging studies involving lncRNAs function and conservation have shown their involvement in several types of biotic and abiotic stresses. Thus, the conservation of lncRNAs among Fabaceae species considering their rapid turnover, suggests they are likely to have been under functional conservation pressure. Our results indicate the potential involvement of lncRNAs in the adaptation of C. langsdorffii in two different biomes. PMID- 30297663 TI - Effect of Low Dose Docosahexaenoic Acid-Rich Fish Oil on Plasma Lipids and Lipoproteins in Pre-Menopausal Women: A Dose-Response Randomized Placebo Controlled Trial. AB - Omega-3 long chain polyunsaturated fatty acid (n-3 LCPUFA) supplementation has been shown to improve plasma lipid profiles in men and post-menopausal women, however, data for pre-menopausal women are lacking. The benefits of intakes less than 1 g/day have not been well studied, and dose-response data is limited. The aim of this study was to determine the effect of low doses of docosahexaenoic acid (DHA)-rich tuna oil on plasma triglyceride (TG) lowering in pre-menopausal women, and investigate if low dose DHA-rich tuna oil supplementation would increase the low-density lipoprotein (LDL) and high-density lipoprotein (HDL) particle sizes. A randomized, double-blind, placebo-controlled trial was conducted, in which 53 healthy pre-menopausal women with mildly elevated plasma TG levels consumed 0, 0.35, 0.7, or 1 g/day n-3 LCPUFA as HiDHATM tuna oil or placebo (Sunola oil) capsules for 8 weeks. Supplementation with 1 g/day n-3 LCPUFA, but not lower doses, reduced plasma TG by 23% in pre-menopausal women. This was reflected in a dose-dependent reduction in very-low-density lipoprotein (VLDL)-TG (R2 = 0.20, p = 0.003). A weak dose-dependent shift in HDL (but not LDL) particle size was identified (R2 = 0.05, p = 0.04). The results of this study indicate that DHA-rich n-3 LCPUFA supplementation at a dose of 1 g/day is an effective TG-lowering agent and increases HDL particle size in pre-menopausal women. PMID- 30297665 TI - Effects of Laser Welding and Post-Weld Heat Treatment on Microstructure and Mechanical Properties of Aged Ti55531 Alloy. AB - As one of the relatively new titanium (Ti) alloys in the engineering field, beta Ti alloy-Ti55531 has attracted a great deal of attention due to its excellent mechanical properties, while a few research papers on weldability and the post weld heat treatment (PWHT) process of Ti55531 have been reported. Based on an orthogonal experiment design, the parameters of laser beam welding (LBW) of Ti55531 alloy with a thickness of 2 mm were optimized. Moreover, the influences of welding parameters and PWHT on the microstructures and performance of the laser-welded joint of Ti55531 were analyzed. The results showed that, for microstructures in different zones of as-welded joints of Ti55531: three forms of alpha phases (i.e., equiaxial alphap phase, lamellar alphaS phase, and alphaGB phase at grain boundaries) were observed in base metal (BM); in the heat affected zone (HAZ), part of lamellar alphaS phase had dissolved while equiaxial alphap phase had grown; the fusion zone (FZ) mainly consisted of beta phase, which presented as coarse columnar crystals. After the PWHT process, the microstructures of the welded joint were changed: in the BM zone, alpha phase at grain boundary disappeared and lamellar alpha phase decreased; in the HAZ, the edge of alphap phase obviously dissolved; in the FZ, plenty of compact needle like alpha phases were observed. The tensile strength of the as-welded joint was about 940 MPa and then increased to 1161 MPa after PWHT, which were 78.4% and 96.8% of that of the original BM respectively. The fracture position transformed from the interface between the FZ and HAZ to the BM during tensile tests after PWHT. PMID- 30297666 TI - Unsupervised Machine Learning for Advanced Tolerance Monitoring of Wire Electrical Discharge Machining of Disc Turbine Fir-Tree Slots. AB - Manufacturing more efficient low pressure turbines has become a topic of primary importance for aerospace companies. Specifically, wire electrical discharge machining of disc turbine fir-tree slots has attracted increasing interest in recent years. However, important issues must be still addressed for optimum application of the WEDM process for fir-tree slot production. The current work presents a novel approach for tolerance monitoring based on unsupervised machine learning methods using distribution of ionization time as a variable. The need for time-consuming experiments to set-up threshold values of the monitoring signal is avoided by using K-means and hierarchical clustering. The developments have been tested in the WEDM of a generic fir-tree slot under industrial conditions. Results show that 100% of the zones classified into Clusters 1 and 2 are related to short-circuit situations. Further, 100% of the zones classified in Clusters 3 and 5 lie within the tolerance band of +/-15 MUm. Finally, the 9 regions classified in Cluster 4 correspond to situations in which the wire is moving too far away from the part surface. These results are strongly in accord with tolerance distribution as measured by a coordinate measuring machine. PMID- 30297667 TI - Analysis of Aggregate Morphological Characteristics for Viscoelastic Properties of Asphalt Mixes Using Simplex Lattice Design. AB - Morphological characteristics of aggregates have direct impacts on performances of asphalt mixes. This paper aims to investigate the effects of the morphological characteristics of fine and coarse aggregates on the high-temperature viscoelastic properties of asphalt mortars and mixtures. For this purpose, an experimental proportion scheme was designed for asphalt mixes prepared with three different types of aggregates (basalt, andesite and pebble/river sand) based on the simplex lattice design (SLD) method. Three morphological parameters were chosen to characterize shape, angularity and texture of aggregates. Afterwards, the uniaxial compression creep test was conducted for asphalt mixes and the high temperature viscoelastic properties were obtained based on Burgers model. The effects of fine and coarse aggregates on the viscoelastic properties are analyzed through asphalt mortars and mixtures, respectively. The results showed that aggregate morphological characteristics correlate with the high-temperature viscoelastic properties of asphalt mixes, especially for fine aggregates. Aggregates with complex morphological characteristics are conducive to improving the deformation recovery and anti-deformation of asphalt mixes. Furthermore, coarse aggregates can enhance the anti-deformation of asphalt mixture effectively due to its skeleton effect. PMID- 30297668 TI - Human Milk Oligosaccharides to Prevent Gut Dysfunction and Necrotizing Enterocolitis in Preterm Neonates. AB - This review focuses on the evidence for health benefits of human milk oligosaccharides (HMOs) for preterm infants to stimulate gut adaptation and reduce the incidence of necrotizing enterocolitis (NEC) in early life. The health benefits of breastfeeding are partly explained by the abundant HMOs that serve as prebiotics and immunomodulators. Gut immaturity in preterm infants leads to difficulties in tolerating enteral feeding and bacterial colonization and a high sensitivity to NEC, particularly when breast milk is insufficient. Due to the immaturity of the preterm infants, their response to HMOs could be different from that in term infants. The concentration of HMOs in human milk is highly variable and there is no evidence to support a specifically adapted high concentration in preterm milk. Further, the gut microbiota is not only different but also highly variable after preterm birth. Studies in pigs as models for preterm infants indicate that HMO supplementation to formula does not mature the gut or prevent NEC during the first weeks after preterm birth and the effects may depend on a certain stage of gut maturity. Supplemented HMOs may become more important for gut protection in the preterm infants when the gut has reached a more mature phase. PMID- 30297669 TI - The Inhibitory Effects of Cyclodepsipeptides from the Entomopathogenic Fungus Beauveria bassiana on Myofibroblast Differentiation in A549 Alveolar Epithelial Cells. AB - Pulmonary fibrosis (PF) is a chronic and fatal lung disease with few treatment options. Although the pathogenesis of PF is not clear, a chronic inflammatory response to continuous damage is considered the cause of pulmonary fibrosis. PF is characterized by excessive accumulation of extracellular matrix (ECM), therefore, inhibition of myofibroblast differentiation is a good therapeutic target for PF. As part of our continuing endeavor to explore biologically active metabolites from insect-associated microbes, we found that the MeOH extract of the culture broth from the entomopathogenic fungus Beauveria bassiana inhibited collagen induction and E-cadherin down-regulation. In order to identify active compounds, we carried out chemical analysis of the MeOH extract with the assistance of LC/MS-guided isolation approach, which led to the successful identification of four cyclodepsipeptides 1-4. Among the isolates, compound 2 showed inhibitory effects on myofibroblast differentiation induced by TGF-beta1. Compound 2 inhibited induction of alpha-SMA and N-cadherin, which are myofibroblast markers, and blocked the accumulation of ECM proteins such as collagen and fibronectin. Overall these findings demonstrate that compound 2 can be used to attenuate pulmonary fibrosis by targeting myo- fibroblast differentiation. PMID- 30297670 TI - Diffusivities and Atomic Mobilities in bcc Ti-Mo-Zr Alloys. AB - beta-type (with bcc structure) titanium alloys have been widely used as artificial implants in the medical field due to their favorable properties. Among them, Ti-Mo alloy attracted numerous interests as metallic biomaterials. Understanding of kinetic characteristics of Ti alloys is critical to understand and manipulate the phase transformation and microstructure evolution during homogenization and precipitation. In this work, diffusion couple technique was employed to investigate the diffusion behaviors in bcc Ti-Mo-Zr alloys. The diffusion couples were prepared and annealed at 1373 K for 72 h and 1473 K for 48 h, respectively. The composition-distance profiles were obtained via electron probe micro-analysis (EPMA). The chemical diffusion coefficients and impurity diffusion coefficients were extracted via the Whittle-Green method and Hall method. The obtained diffusion coefficients were assessed to develop a self consistent atomic mobility database of bcc phase in Ti-Mo-Zr system. The calculated diffusion coefficients were compared with the experimental results. They showed good agreement. Simulations were implemented by Dictra Module in Thermo-Calc software. The predicted composition-distance profiles, inter diffusion flux, and diffusion paths are consistent with experimental data, confirming the accuracy of the database. PMID- 30297671 TI - One-Step Fabrication of Three-Dimensional Fibrous Collagen-Based Macrostructure with High Water Uptake Capability by Coaxial Electrospinning. AB - One step fabrication of the three dimension (3D) fibrous structure of Collagen-g poly(MMA-co-EA)/Nylon6 was investigated by controlling the experimental conditions during coaxial electrospinning. This 3D fibrous structure is the result of interactions of two polymeric systems with a varied capability to be electrostatically polarized under the influence of the external electric field; the solution with the higher conductivity into the inner spinneret and the solution with the lesser conductivity into the outer capillary of the coaxial needle. This set-up was to obtain bimodal fiber fabrication in micro and nanoscale developing a spatial structure; the branches growing off a trunk. The resultant 3D collagen-based fibrous structure has two distinguished configurations: microfibers of 6.9 +/- 2.2 um diameter gap-filled with nanofibers of 216 +/- 49 nm diameter. The 3D fibrous structure can be accumulated at an approximate height of 4 cm within 20 min. The mechanism of the 3D fibrous structure and the effect of experimental conditions, the associated hydration degree, water uptake and degradation rate were also investigated. This highly stable 3D fibrous structure has great potential end-uses benefitting from its large surface area and high water uptake which is caused by the high polarity and spatial orientation of collagen-based macrostructure. PMID- 30297673 TI - Decentralized Cooperative Localization with Fault Detection and Isolation in Robot Teams. AB - Robot localization, particularly multirobot localization, is an important task for multirobot teams. In this paper, a decentralized cooperative localization (DCL) algorithm with fault detection and isolation is proposed to estimate the positions of robots in mobile robot teams. To calculate the interestimate correlations in a distributed manner, the split covariance intersection filter (SCIF) is applied in the algorithm. Based on the split covariance intersection filter cooperative localization (SCIFCL) algorithm, we adopt fault detection and isolation (FDI) to improve the robustness and accuracy of the DCL results. In the proposed algorithm, the signature matrix of the original FDI algorithm is modified for application to DCL. A simulation-based comparative study is conducted to demonstrate the effectiveness of the proposed algorithm. PMID- 30297675 TI - Ceramide Synthase 6: Comparative Analysis, Phylogeny and Evolution. AB - Ceramide synthase 6 (CerS6, also known as LASS6) is one of the six members of ceramide synthase gene family in humans. Comparisons of CerS6 amino acid sequences and structures as well as of CerS6 gene structures/locations were conducted using data from several vertebrate genome projects. A specific role for the CerS6 gene and protein has been identified as the endoplasmic reticulum C14- and C16-ceramide synthase. Mammalian CerS6 proteins share 90-100% similarity among different species, but are only 22-63% similar to other CerS family members, suggesting that CerS6 is a distinct gene family. Sequence alignments, predicted transmembrane, lumenal and cytoplasmic segments and N-glycosylation sites were also investigated, resulting in identification of the key conserved residues, including the active site as well as C-terminus acidic and serine residues. Mammalian CerS6 genes contain ten exons, are primarily located on the positive strands and transcribed as two major isoforms. The human CERS6 gene promoter harbors a large CpG island (94 CpGs) and multiple transcription factor binding sites (TFBS), which support precise transcriptional regulation and signaling functions. Additional regulation is conferred by 15 microRNA (miRNA) target sites identified in the CERS6 3'-UTR region. Phylogenetic analysis of the vertebrate CerS1-6 gene families relationships supports a major role for the CerS6 enzyme that is strongly conserved throughout vertebrate evolution.

AB - Hydroxyapatite (HAp) is the main inorganic component and an essential part of hard bone and teeth. Due to its excellent biocompatibility, bioactivity, and osteoconductivity, synthetic HAp has been widely used as a bone substitute, cell carrier, and therapeutic gene or drug carrier. Recently, numerous studies have demonstrated that strontium-substituted hydroxyapatite (SrHAp) not only enhances osteogenesis but also inhibits adipogenesis in mesenchymal stem cells. Mesoporous SrHAp has been successfully synthesized via a traditional template-based process and has been found to possess better drug loading and release efficiencies than SrHAp. In this study, strontium-substituted hydroxyapatite-CaO-CaCO3 nanofibers with a mesoporous structure (mSrHANFs) were fabricated using a sol-gel method followed by electrospinning. X-ray diffraction analysis revealed that the contents of CaO and CaCO3 in the mSrHANFs decreased as the doping amount of Sr increased. Scanning electron microscopy (SEM) images showed that the average diameter of the mSrHANFs was approximately 200~300 nm. The N2 adsorption desorption isotherms demonstrated that the mSrHANFs possessed a mesoporous structure and that the average pore size was approximately 20~25 nm. Moreover, the mSrHANFs had excellent drug- loading efficiency and could retard the burst release of tetracycline (TC) to maintain antibacterial activity for over 3 weeks. Hence, mSrHANFs have the potential to be used as drug carriers in bone tissue engineering. PMID- 30297672 TI - Proteoglycans Are Attractive Biomarkers and Therapeutic Targets in Hepatocellular Carcinoma. AB - Proteoglycans, which consist of a protein core and glycosaminoglycan chains, are major components of the extracellular matrix and play physiological roles in maintaining tissue homeostasis. In the carcinogenic tissue microenvironment, proteoglycan expression changes dramatically. Altered proteoglycan expression on tumor and stromal cells affects cancer cell signaling pathways, which alters growth, migration, and angiogenesis and could facilitate tumorigenesis. This dysregulation of proteoglycans has been implicated in the pathogenesis of diseases such as hepatocellular carcinoma (HCC) and the underlying mechanism has been studied extensively. This review summarizes the current knowledge of the roles of proteoglycans in the genesis and progression of HCC. It focuses on well investigated proteoglycans such as serglycin, syndecan-1, glypican 3, agrin, collagen XVIII/endostatin, versican, and decorin, with particular emphasis on the potential of these factors as biomarkers and therapeutic targets in HCC regarding the future perspective of precision medicine toward the "cure of HCC". PMID- 30297677 TI - Degradation of the In-plane Shear Modulus of Structural BFRP Laminates Due to High Temperature. AB - The behavior of fiber reinforced polymer (FRP) composites at high temperature is a critical issue that needs to be clearly understood for their structural uses in civil engineering. However, due to technical difficulties during testing at high temperature, limited experimental investigations have been conducted regarding the thermal behavior of basalt fiber reinforced polymer (BFRP) composites, especially for the in-plane shear modulus of BFRP laminates. To this end, both an analytical derivation and an experimental program were carried out in this work to study the in-plane shear modulus of BFRP laminates. After the analytical derivation, the in-plane shear modulus was investigated as a function of the elastic modulus in different directions (0 degrees , 45 degrees and 90 degrees of the load-to-fiber angle) and Poisson's ratio in the fiber direction. To obtain the in-plane shear modulus, the four parameters were tested at different temperatures from 20 to 250 degrees C. A novel non-contacting digital image correlation (DIC) sensing system was adopted in the high-temperature tests to measure the local strain field on the FRP samples. Based on the test results, it was found that the elastic moduli in different directions were reduced to a very low level (less than 20%) from 20 to 250 degrees C. Furthermore, the in-plane shear modulus of BFRP at 250 degrees C was only 3% of that at 20 degrees C. PMID- 30297676 TI - Comparative RNA-Seq Analysis of High- and Low-Oil Yellow Horn During Embryonic Development. AB - Yellow horn (Xanthoceras sorbifolium Bunge) is an endemic oil-rich shrub that has been widely cultivated in northern China for bioactive oil production. However, little is known regarding the molecular mechanisms that contribute to oil content in yellow horn. Herein, we measured the oil contents of high- and low-oil yellow horn embryo tissues at four developmental stages and investigated the global gene expression profiles through RNA-seq. The results found that at 40, 54, 68, and 81 days after anthesis, a total of 762, 664, 599, and 124 genes, respectively, were significantly differentially expressed between the high- and low-oil lines. Gene ontology (GO) enrichment analysis revealed some critical GO terms related to oil accumulation, including acyl-[acyl-carrier-protein] desaturase activity, pyruvate kinase activity, acetyl-CoA carboxylase activity, and seed oil body biogenesis. The identified differentially expressed genes also included several transcription factors, such as, AP2-EREBP family members, B3 domain proteins and C2C2-Dof proteins. Several genes involved in fatty acid (FA) biosynthesis, glycolysis/gluconeogenesis, and pyruvate metabolism were also up-regulated in the high-oil line at different developmental stages. Our findings indicate that the higher oil accumulation in high-oil yellow horn could be mostly driven by increased FA biosynthesis and carbon supply, i.e. a source effect. PMID- 30297678 TI - Early Life Professional and Layperson Support Reduce Poor Oral Hygiene Habits in Toddlers-A Prospective Birth Cohort Study. AB - Oral health behaviours of children are formulated from a very young age. Formation of those behaviours among very young children is dependent on their mothers/caregivers who may themselves require support from the health profession or laypersons. The study aimed to investigate if early life visits for check-up and dental advice and perceived support improved oral health behaviours as practiced by mothers of toddlers aged 24-30 months old. Data from a population base birth cohort study in South Australia was used. The study recruited and followed mothers of newborn children from birth to age 24-30 months. Parental questionnaires collected information about socioeconomic factors, dental visiting patterns, and oral health behaviours as practiced by the mothers for their child. Self-reported putting a child to bed with a bottle and brushing a child's teeth were the outcome variables. The two main exposures of this study were (1) early visiting for a dental advice, and (2) layperson support that a mother received in the first two years of having the child. Data were analysed progressively from bivariate to multivariable regression models. A total of 1183 mother/child dyads had complete data. The retained sample was representative of the population. Approximately 36% of mothers put their child to bed with a bottle and 26% of mothers did not brush their child's teeth the night before. Around 29% of children had a visit for dental check-up and 80% of mothers reported having lay support. There were gradients in the outcome variables by socioeconomic factors and the main exposures. Multivariable regression models reported that having no dental visit for advice and having no lay support were associated with 1.30 and 1.21 imes higher rates of putting a child to bed with a bottle, respectively. Having no dental visit for advice was associated with a 1.37-times higher rate of not brushing a child's teeth, controlling for other factors. This population based birth cohort study confirmed importance of early life dental visit for check-up and support for mothers of young children in establishing oral health behaviours of young children. PMID- 30297680 TI - Beamforming Design for Full-Duplex SWIPT with Co-Channel Interference in Wireless Sensor Systems. AB - The simultaneous wireless information and power transfer (SWIPT) technique has been regarded as an appealing approach to prolong the lifetime of wireless sensor networks. However, co-channel interferences with SWIPT in wireless networks have not been investigated from a green communication perspective. In this paper, joint transmit and receive beamforming design for a full-duplex multiple-input multiple-output amplify-and-forward relay system with simultaneous wireless information and power transfer in WSNs is investigated. Multiple co-channel interferers are considered at the relay and destination sensor nodes. To minimize the mean-squared-error of the system, joint source and relay beamforming optimization is proposed while guaranteeing the transmit power constraints and destination's energy harvesting constraint. An iterative algorithm based on alternating optimization with successive convex approximation which converges to a local optimum is proposed to solve the non-convex problem. Moreover, a low complexity scheme is derived to reduce the computational complexity. Simulations for MSE versus iterations and MSE versus signal-to-noise ratio (SNR) demonstrate the convergence and good performance of the proposed schemes. PMID- 30297679 TI - Differential and Overlapping Effects of 20,23(OH)2D3 and 1,25(OH)2D3 on Gene Expression in Human Epidermal Keratinocytes: Identification of AhR as an Alternative Receptor for 20,23(OH)2D3. AB - A novel pathway of vitamin D activation by CYP11A has previously been elucidated. To define the mechanism of action of its major dihydroxy-products, we tested the divergence and overlap between the gene expression profiles of human epidermal keratinocytes treated with either CYP11A1-derived 20,23(OH)2D3 or classical 1,25(OH)2D3. Both secosteroids have significant chemical similarity with the only differences being the positions of the hydroxyl groups. mRNA was isolated and examined by microarray analysis using Illumina's HumanWG-6 chip/arrays and subsequent bioinformatics analyses. Marked differences in the up- and downregulated genes were observed between 1,25(OH)2D3- and 20,23(OH)2D3-treated cells. Hierarchical clustering identified both distinct, opposite and common (overlapping) gene expression patterns. CYP24A1 was a common gene strongly activated by both compounds, a finding confirmed by qPCR. Ingenuity pathway analysis identified VDR/RXR signaling as the top canonical pathway induced by 1,25(OH)2D3. In contrast, the top canonical pathway induced by 20,23(OH)2D3 was AhR, with VDR/RXR being the second nuclear receptor signaling pathway identified. QPCR analyses validated the former finding by revealing that 20,23(OH)2D3 stimulated CYP1A1 and CYP1B1 gene expression, effects located downstream of AhR. Similar stimulation was observed with 20(OH)D3, the precursor to 20,23(OH)2D3, as well as with its downstream metabolite, 17,20,23(OH)3D3. Using a Human AhR Reporter Assay System we showed marked activation of AhR activity by 20,23(OH)2D3, with weaker stimulation by 20(OH)D3. Finally, molecular modeling using an AhR LBD model predicted vitamin D3 hydroxyderivatives to be good ligands for this receptor. Thus, our microarray, qPCR, functional studies and molecular modeling indicate that AhR is the major receptor target for 20,23(OH)2D3, opening an exciting area of investigation on the interaction of different vitamin D3 hydroxyderivatives with AhR and the subsequent downstream activation of signal transduction pathways in a cell-type-dependent manner. PMID- 30297681 TI - Pharmacokinetic, Antiproliferative and Apoptotic Effects of Phenolic Acids in Human Colon Adenocarcinoma Cells Using In Vitro and In Silico Approaches. AB - Colon cancer is the second most common cause of cancer deaths in the USA and Europe. Despite aggressive therapies, many tumors are resistant to current treatment protocols and epidemiological data suggest that diet is a major factor in the etiology of colon cancer. This study aimed to evaluate the antioxidant activity and the influence of 3,4-dihydroxyphenylacetic (3,4-DHPAA), p-coumaric (p-CoA), vanillic (VA) and ferulic (FA) acids on cell viability, cell cycle progression, and rate of apoptosis in human colon adenocarcinoma cells (HT-29). The results showed that all compounds tested reduce cell viability in human colon cancer cells. 3,4-DHPAA promoted the highest effect antiproliferative with an increase in the percentage of cells in G0/G1 phase, accompanied by a reduction of cells in G2/M phase. Cell cycle analysis of VA and FA showed a decrease in the proportion of cells in G0/G1 phase (10.0 uM and 100.0 uM). p-CoA and FA acids increased the percentage of apoptotic cells and non-apoptotic cells. 3,4-DHPAA seems to be the substance with the greatest potential for in vivo studies, opening thus a series of perspectives on the use of these compounds in the prevention and treatment of colon cancer. PMID- 30297682 TI - Importance of Mineral Nutrition for Mitigating Aluminum Toxicity in Plants on Acidic Soils: Current Status and Opportunities. AB - Aluminum (Al) toxicity is one of the major limitations that inhibit plant growth and development in acidic soils. In acidic soils (pH < 5.0), phototoxic-aluminum (Al3+) rapidly inhibits root growth, and subsequently affects water and nutrient uptake in plants. This review updates the existing knowledge concerning the role of mineral nutrition for alleviating Al toxicity in plants to acid soils. Here, we explored phosphorus (P) is more beneficial in plants under P-deficient, and Al toxic conditions. Exogenous P addition increased root respiration, plant growth, chlorophyll content, and dry matter yield. Calcium (Ca) amendment (liming) is effective for correcting soil acidity, and for alleviating Al toxicity. Magnesium (Mg) is able to prevent Al migration through the cytosolic plasma membrane in root tips. Sulfur (S) is recognized as a versatile element that alleviates several metals toxicity including Al. Moreover, silicon (Si), and other components such as industrial byproducts, hormones, organic acids, polyamines, biofertilizers, and biochars played promising roles for mitigating Al toxicity in plants. Furthermore, this review provides a comprehensive understanding of several new methods and low-cost effective strategies relevant to the exogenous application of mineral nutrition on Al toxicity mitigation. This information would be effective for further improvement of crop plants in acid soils. PMID- 30297685 TI - Attenuation of Morphine Withdrawal Syndrome by Prosopis Farcta Extract and Its Bioactive Component Luteolin in Comparison with Clonidine in Rats. AB - BACKGROUND Today, the plant Prosopis farcta is frequently used for traditional medicinal purposes. The aim of this study was the identification of luteolin in P. farcta extract (PFE) and to evaluate its effect on morphine discontinuation syndrome in rats. MATERIAL AND METHODS Using high-performance liquid chromatography (HPCL), luteolin was evaluated in PFE. The frequency of behavioral symptoms of morphine withdrawal (jumping, rearing, and teeth chattering) induced by naloxone challenge were illustrated in morphine-dependent rats receiving PFE, luteolin, saline, or clonidine. LD50 of PFE and luteolin was 540 mg/kg and 150 mg/kg, respectively. Signs of behavioral morphine withdrawal in rats were significantly inhibited by chronic co-administration of PFE, luteolin, or clonidine with morphine. RESULTS This study showed that PFE was less effective than clonidine at a dose of 100 mg/kg, and at doses of 200 mg/kg and 300 mg/kg it was comparable to clonidine, and did not show a significant difference in the reduction of morphine withdrawal symptoms. Luteolin was comparable in 30 mg/kg, 60 mg/kg, and 90 mg/kg with clonidine to reduce the frequency of morphine withdrawal symptoms. PFE can be used as a source of luteolin. CONCLUSIONS The study findings suggest that PFE and luteolin might reduce the signs of narcotic withdrawal. Due to a similar effect to clonidine, its mechanism of action might be through the protein kinase A pathway and might have human therapeutic potential. PMID- 30297684 TI - Supplementary Light Source Affects the Growth and Development of Codonopsis lanceolata Seedlings. AB - Codonopsis lanceolata is widely used in traditional medicine and diets. However, there is no optimal protocol for the commercial production of C. lanceolata seedlings. This study was carried out to find the optimum supplementary light source for the production of C. lanceolata seedlings. Seedlings were grown for four weeks in a glasshouse with an average daily light intensity of 490 MUmol.m 2.s-1 photosynthetic photon flux density (PPFD) coming from the sun and a 16-h daily supplementary lighting at 120 MUmol.m-2.s-1 PPFD from either high-pressure sodium (HPS), metal halide (MH), far-red (FR), white LED (LED-w), or mixed (white: red: blue = 1:2:1) LEDs (LED-mix). The results showed that the greatest total biomass, stem diameter, ratio of shoot weight to shoot length, root biomass, and ratio of root weight to shoot weight were found in seedlings grown under supplementary LED-mix. Meanwhile, the stomatal properties and soluble sugar contents were improved for seedlings in LED-mix. The contents of starch, total phenols, and flavonoids were the greatest for seedlings in LED-w and LED-mix. The expression of photosynthetic proteins and genes in seedlings was also enhanced by LED-mix. Overall, these results suggest that LED-mix is advantageous to the photosynthetic potential and the accumulation of biomass, carbohydrates and secondary metabolites in C. lanceolata. PMID- 30297683 TI - Heat-Shock-Induced Removal of Transgenes Using the Gene-Deletor System in Hybrid Aspen (Populus tremula * P. tremuloides). AB - To evaluate the efficacy of the gene-deletor system in aspen, we evaluated the system for foreign gene removal in a hybrid aspen clone, INRA 353-53 (Populus tremula * P. tremuloides). The recombinase flipping DNA (FLP) gene was under the control of the heat-inducible promoter of Gmhsp17.6-L, and the beta-glucuronidase (gusA) gene which was under the control of the 35S promoter and were constructed using the gene-deletor system in the pCaLFGmFNLFG vector. Six transgenic plants and their sublines were heated at 42 degrees C for 8 h and gene deletion was verified by polymerase chain reaction (PCR). Three lines exhibited partial transgene deletion while the remaining three lines did not delete. Transgenic lines were evaluated by Southern-blot analyses, verifying that the six transgenic plant lines all had a single copy of transfer DNA (t-DNA). Two partial-deletion lines and two non-deletion lines were analysed for methylation and expression of promoter and recombinase. Hardly any methylation was detected in the Gmhsp17.6-L promoter or recombinase FLP gene sequences, however, the expression of the promoter and recombinase was increased significantly in the partial-deletion compared with the non-deletion line after heat-shock treatment. These results suggest that the excision efficiency had no direct relationship with methylation status of the Gmhsp17.6-L promoter and FLP recombinase, yet was affected by the expression of the Gmhsp17.6-L and FLP after heat-shock treatment. PMID- 30297686 TI - Risk Factors of Acute Rejection in Patients with BK Nephropathy After Reduction of Immunosuppression. AB - BACKGROUND BK nephropathy (BKN) affects graft function and increases the risk of graft failure. The reduction of immunosuppression is the main treatment for BKN. However, acute rejection may develop following immunosuppression reduction, and data regarding the risk factors of acute rejection during the post-reduction period are insufficient. MATERIAL AND METHODS Of 758 patients who received a kidney transplantation (KT) between 2008 and 2011, 79 who underwent immunosuppression reduction as BKN treatment were enrolled. The risk factors of acute rejection after immunosuppression reduction were identified using multivariate logistic regression analysis. RESULTS During the median follow-up period (75 months), acute rejection developed in 21.5% of study group patients and in 22.5% of KT recipients without BKN. The rejection group showed a trend of higher body mass index (24.13+/-3.92 vs. 22.40+/-3.31 kg/m2, P=0.070) and lower tacrolimus levels than the no rejection group, although mycophenolate mofetil (MMF) doses were not lower in the rejection group. The rejection group showed worse graft survival than the no rejection group (P=0.001 by the log rank test). A greater number of patients in the rejection group exhibited reduced calcineurin inhibitor (CNI) level by >20% at 1 month after initial BKV detection (34.2% vs. 7.9%, P=0.008). Multivariate analysis indicated that the peak BKV PCR level (odds ratio [OR], 0.136; 95% confidence interval [CI], 0.025-0.732; P=0.020), MMF discontinuation (vs. MMF reduction; OR, 0.112; 95% CI, 0.020-0.618; P=0.012) and CNI level reduction >20% (OR, 33.752; 95% CI, 4.263-267.251; P=0.001) were significantly associated with acute rejection. CONCLUSIONS Acute rejection after immunosuppression reduction for BKN showed worse allograft survival than the patients without acute rejection. In addition, a CNI dose reduction >20% at 1 month after the initial BKV detection can increase the risk of acute rejection. PMID- 30297687 TI - Clinical Value and Diagnostic Accuracy of 3.0T Multi-Parameter Magnetic Resonance Imaging in Traumatic Brachial Plexus Injury. AB - BACKGROUND The aim of this study was to evaluate the clinical value and diagnostic accuracy of 3.0T multi-parameter magnetic resonance imaging (MRI) in traumatic brachial plexus injury. MATERIAL AND METHODS Twenty-five healthy volunteers and 28 patients with clinically confirmed traumatic brachial plexus injury were enrolled in this study. Bilateral brachial plexus imaging was performed using conventional sequences (T1WI, T2WI), short time inversion recovery (STIR), balanced fast field echo (balance-FFE), and diffusion weighted imaging with background suppression (DWIBS). The MRI diagnosis was compared with intraoperative electromyography and surgery. RESULTS Brachial plexus injuries were classified based on the anatomic locations. There were 16 patients with pre ganglionic injury and 12 patients with post-ganglionic injury. The pre-ganglionic injury included ruptured nerve roots, stiff nerve roots, traumatic meningeal cysts, black line sign, spinal cord edema, and thickened nerve root sleeve. The post-ganglionic injury included thickened nerve roots, disappearance of normal nerve root structure or disrupted continuity of the nerve, stiff nerve roots, pseudo-neuroma, and abnormalities in the adjacent soft tissues. Comparing the results from MRI and surgery, the sensitivity, specificity, and accuracy of MRI examination were 93.55%, 71.43%, and 89.47% respectively for preganglionic injury, and 91.30%, 60.00%, and 85.71% respectively for postganglionic injury. CONCLUSIONS The combination of STIR, balance-FFE, and DWIBS sequences can display brachial plexus pre-ganglionic and post-ganglionic injury clearly, effectively, and accurately. PMID- 30297688 TI - Paradoxical Bronchoconstriction with Short-Acting Beta Agonist. AB - : BACKGROUND Asthma is a common disease in the U.S. POPULATION: Initial therapy in the stepwise approach for asthma management is short-acting beta2-agonist (SABA) therapy as needed for symptom control. However, a significant adverse event that can occur with administration is bronchospasm. Here, we report a case of paradoxical bronchospasm with administration of SABAs during multiple pulmonary function tests (PFTs). CASE REPORT A 25-year-old, non-smoking, African American male with a history of moderate asthma and allergic rhinitis treated with fluticasone/salmeterol diskus, albuterol hydrofluoroalkane (HFA) inhaler, and montelukast presented to our clinic complaining of recurrent episodes of acute shortness of breath immediately following each administration of albuterol for 4 weeks. PFTs were performed with levalbuterol (Xopenex) and albuterol (ProAir), yielding significant decrease in forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC). Nebulized albuterol and ipratropium bromide also improved FEV1 and FVC. He was successfully transitioned to an ipratropium rescue inhaler for asthma exacerbations. CONCLUSIONS Paradoxical bronchoconstriction is the unexpected constriction of smooth muscle walls of the bronchi that occurs in the setting of an expected bronchodilatory response. This phenomenon has been observed with beta2-agonist-containing inhaler formulations and is an under-recognized adverse event. Theories suggest that the formulation excipients can trigger airway hyperresponsiveness in patients with allergically inflamed airways. Removal of excipients or use of anticholinergic inhalers improved respiratory function. Clinicians should be aware of paradoxical bronchospasm as an adverse effect with common inhaler formulations containing beta2-agonists and counsel patients accordingly in the appropriate clinical setting. PMID- 30297689 TI - A sulfotransferase dosage-dependently regulates mouthpart polyphenism in the nematode Pristionchus pacificus. AB - Polyphenism, the extreme form of developmental plasticity, is the ability of a genotype to produce discrete morphologies matched to alternative environments. Because polyphenism is likely to be under switch-like molecular control, a comparative genetic approach could reveal the molecular targets of plasticity evolution. Here we report that the lineage-specific sulfotransferase SEUD-1, which responds to environmental cues, dosage-dependently regulates polyphenism of mouthparts in the nematode Pristionchus pacificus. SEUD-1 is expressed in cells producing dimorphic morphologies, thereby integrating an intercellular signalling mechanism at its ultimate target. Additionally, multiple alterations of seud-1 support it as a potential target for plasticity evolution. First, a recent duplication of seud-1 in a sister species reveals a direct correlation between genomic dosage and polyphenism threshold. Second, inbreeding to produce divergent polyphenism thresholds resulted in changes in transcriptional dosage of seud-1. Our study thus offers a genetic explanation for how plastic responses evolve. PMID- 30297690 TI - Bacterial coinfection restrains antiviral CD8 T-cell response via LPS-induced inhibitory NK cells. AB - Infection of specific pathogen-free mice with lymphocytic choriomeningitis virus (LCMV) is a widely used model to study antiviral T-cell immunity. Infections in the real world, however, are often accompanied by coinfections with unrelated pathogens. Here we show that in mice, systemic coinfection with E. coli suppresses the LCMV-specific cytotoxic T-lymphocyte (CTL) response and virus elimination in a NK cell- and TLR2/4-dependent manner. Soluble TLR4 ligand LPS also induces NK cell-mediated negative CTL regulation during LCMV infection. NK cells in LPS-treated mice suppress clonal expansion of LCMV-specific CTLs by a NKG2D- or NCR1-independent but perforin-dependent mechanism. These results suggest a TLR4-mediated immunoregulatory role of NK cells during viral-bacterial coinfections. PMID- 30297691 TI - Modulation of proteoglycan receptor PTPsigma enhances MMP-2 activity to promote recovery from multiple sclerosis. AB - Multiple Sclerosis (MS) is characterized by focal CNS inflammation leading to the death of oligodendrocytes (OLs) with subsequent demyelination, neuronal degeneration, and severe functional deficits. Inhibitory chondroitin sulfate proteoglycans (CSPGs) are increased in the extracellular matrix in the vicinity of MS lesions and are thought to play a critical role in myelin regeneration failure. We here show that CSPGs curtail remyelination through binding with their cognate receptor, protein tyrosine phosphatase sigma (PTPsigma) on oligodendrocyte progenitor cells (OPCs). We report that inhibition of CSPG/PTPsigma signaling by systemically deliverable Intracellular Sigma Peptide (ISP), promotes OPC migration, maturation, remyelination, and functional recovery in animal models of MS. Furthermore, we report a downstream molecular target of PTPsigma modulation in OPCs involving upregulation of the protease MMP-2 that allows OPCs to enzymatically digest their way through CSPGs. In total, we demonstrate a critical role of PTPsigma/CSPG interactions in OPC remyelination in MS. PMID- 30297693 TI - Combined computational and experimental investigation of high temperature thermodynamics and structure of cubic ZrO2 and HfO2. AB - Structure and thermodynamics of pure cubic ZrO2 and HfO2 were studied computationally and experimentally from their tetragonal to cubic transition temperatures (2311 and 2530 degrees C) to their melting points (2710 and 2800 degrees C). Computations were performed using automated ab initio molecular dynamics techniques. High temperature synchrotron X-ray diffraction on laser heated aerodynamically levitated samples provided experimental data on volume change during tetragonal-to-cubic phase transformation (0.55 +/- 0.09% for ZrO2 and 0.87 +/- 0.08% for HfO2), density and thermal expansion. Fusion enthalpies were measured using drop and catch calorimetry on laser heated levitated samples as 55 +/- 7 kJ/mol for ZrO2 and 61 +/- 10 kJ/mol for HfO2, compared with 54 +/- 2 and 52 +/- 2 kJ/mol from computation. Volumetric thermal expansion for cubic ZrO2 and HfO2 are similar and reach (4 +/- 1).10-5/K from experiment and (5 +/- 1).10 5/K from computation. An agreement with experiment renders confidence in values obtained exclusively from computation: namely heat capacity of cubic HfO2 and ZrO2, volume change on melting, and thermal expansion of the liquid to 3127 degrees C. Computed oxygen diffusion coefficients indicate that above 2400 degrees C pure ZrO2 is an excellent oxygen conductor, perhaps even better than YSZ. PMID- 30297692 TI - Designed synthesis of stable light-emitting two-dimensional sp2 carbon-conjugated covalent organic frameworks. AB - Covalent organic frameworks enable the topological connection of organic chromophores into pi lattices, making them attractive for creating light-emitting polymers that are predesignable for both the primary- and high-order structures. However, owing to linkages, covalent organic frameworks are either unstable or poor luminescent, leaving the practical synthesis of stable light-emitting frameworks challenging. Here, we report the designed synthesis of sp2 carbon conjugated frameworks that combine stability with light-emitting activity. The C=C linkages topologically connect pyrene knots and arylyenevinylene linkers into two-dimensional all sp2 carbon lattices that are designed to be pi conjugated along both the x and y directions and develop layer structures, creating exceptionally stable frameworks. The resulting frameworks are capable of tuning band gap and emission by the linkers, are highly luminescent under various conditions and can be exfoliated to produce brilliant nanosheets. These results suggest a platform based on sp2 carbon frameworks for designing robust photofunctional materials. PMID- 30297694 TI - TIP55, a splice isoform of the KAT5 acetyltransferase, is essential for developmental gene regulation and organogenesis. AB - Regulation of chromatin structure is critical for cell type-specific gene expression. Many chromatin regulatory complexes exist in several different forms, due to alternative splicing and differential incorporation of accessory subunits. However, in vivo studies often utilize mutations that eliminate multiple forms of complexes, preventing assessment of the specific roles of each. Here we examined the developmental roles of the TIP55 isoform of the KAT5 histone acetyltransferase. In contrast to the pre-implantation lethal phenotype of mice lacking all four Kat5 transcripts, mice specifically deficient for Tip55 die around embryonic day 11.5 (E11.5). Prior to developmental arrest, defects in heart and neural tube were evident in Tip55 mutant embryos. Specification of cardiac and neural cell fates appeared normal in Tip55 mutants. However, cell division and survival were impaired in heart and neural tube, respectively, revealing a role for TIP55 in cellular proliferation. Consistent with these findings, transcriptome profiling revealed perturbations in genes that function in multiple cell types and developmental pathways. These findings show that Tip55 is dispensable for the pre- and early post-implantation roles of Kat5, but is essential during organogenesis. Our results raise the possibility that isoform specific functions of other chromatin regulatory proteins may play important roles in development. PMID- 30297695 TI - Quinoa whole grain diet compromises the changes of gut microbiota and colonic colitis induced by dextran Sulfate sodium in C57BL/6 mice. AB - A plethora of evidence highlights that the dysbiosis of gut microbiota is a critical factor for inflammatory bowel disease (IBD). Both in vivo and in vitro studies have demonstrated that quinoa possesses potential prebiotic effects. The present study aims to examine the potential in using quinoa to ameliorate the dysbiosis and colitis induced by dextran sodium sulfate (DSS). A total of 40 C57BL/6 mice were fed either an AIN-93M diet or a quinoa-based diet, separately. Colitis was induced for 10 animals/dietary group with a 5-days exposure to 2.5% DSS. The clinical symptoms were monitored every other day, and the gut microbiota was characterized by 16S rRNA gene sequencing. The results indicated that consumption of quinoa lessened clinical symptoms as indicated by the reduced disease activity index and the degree of histological damage (P < 0.05). As expected, the DSS treatment induced significant dysbiosis of gut microbiota in mice on an AIN-93M diet. However, compared to mice fed the AIN-93M diet, the consumption of quinoa alleviated the DSS-induced dysbiosis remarkably, as indicated by increased species richness and diversity, decreased abnormal expansion of phylum Proteobacteria, and decreased overgrowth of genera Escherichia/Shigella and Peptoclostridium (P < 0.05). The relative abundances of Firmicutes and Bacteroidetes were less altered in mice fed with quinoa comparing to those mice fed the AIN-93M diet. In summary, the consumption of quinoa suppressed the dysbiosis of gut microbiota and alleviated clinical symptoms induced by DSS, indicating the potential to utilize quinoa as a dietary approach to improve intestinal health. PMID- 30297696 TI - Tender leaf and fully-expanded leaf exhibited distinct cuticle structure and wax lipid composition in Camellia sinensis cv Fuyun 6. AB - The goal of the present study was to compare the structural and compositional differences of cuticle between tender leaf and fully-expanded leaf in Camellia sinensis, and provide metabolic base for the further characterization of wax biosynthesis in this economically important crop species. The tender second leaf and the fully-expanded fifth leaf from new twig were demonstrated to represent two different developmental stages, their cuticle thickness were measured by transmission electron microscopy. The thickness of the adaxial cuticle on the second and fifth leaf was 1.15 um and 2.48 um, respectively; the thickness of the abaxial cuticle on the second and fifth leaf was 0.47 um and 1.05 um, respectively. The thickness of the epicuticular wax layer from different leaf position or different sides of same leaf were similar. However, the intracuticular wax layer of the fifth leaf was much thicker than that of the second leaf. Total wax lipids were isolated from the second leaf and the fifth leaf, respectively. Gas chromatography-mass spectrometry analysis identified 51 wax constituents belonging to 13 chemical classes, including esters, glycols, terpenoids, fatty acids and their derivatives. Wax coverage on the second and fifth leaf was 4.76 ug/cm2 and 15.38 ug/cm2, respectively. Primary alcohols dominated in the tender second leaf. However, triterpenoids were the major components from the fully-expanded fifth leaf. The predominant carbon chains varied depending on chemical class. These data showed that the wax profiles of Camellia sinensis leaves are development stage dependent, suggesting distinct developmental dependent metabolic pathways and regulatory mechanisms. PMID- 30297698 TI - Venous thromboembolism laboratory testing (factor V Leiden and factor II c.*97G>A), 2018 update: a technical standard of the American College of Medical Genetics and Genomics (ACMG). AB - Factor V Leiden and factor II c.*97G>A (formerly referred to as prothrombin 20210G>A) are the two most common genetic variants associated with venous thromboembolism (VTE). Testing for these variants is one of the most common referrals in clinical genetics laboratories. While the methodologies for testing these two variants are relatively straightforward, the clinical implementation can be complicated with regard to test indications, risk assessment of occurrence and recurrence of VTE, and related genetic counseling. This document provides an overview of VTE, information about the variants and their influence on risk, considerations before initiating genetic testing, and the clinical and analytical sensitivity and specificity of the tests. Key information that should be included in the laboratory report is also provided. Disease-specific statements are intended to augment the general American College of Medical Genetics and Genomics (ACMG) technical standards for clinical genetics laboratories. Individual laboratories are responsible for meeting the Clinical Laboratory Improvement Amendments (CLIA)/College of American Pathologists (CAP) quality assurance standards with respect to appropriate sample documentation, assay validation, general proficiency testing, and quality control measures. This 2018 edition of the ACMG technical standard updates and supersedes the 2005 edition on this topic. It is designed to be a checklist for genetic testing professionals who are already familiar with the disease and the methods of analysis. PMID- 30297697 TI - Aberrant neuronal differentiation is common in glioma but is associated neither with epileptic seizures nor with better survival. AB - The mechanisms of glioma-associated seizures (GAS) have yet to be fully elucidated. Proneural subtype, isocitrate dehydrogenase 1 (IDH1) mutations, and epileptic seizures are closely associated suggesting that aberrant neuronal differentiation contributes to glioma-associated seizures. In a population-based cohort (n = 236), lack of stem cell marker expression (nestin, musashi) was significantly associated with IDH1 mutations and GAS at diagnosis. In vitro data suggested an association of IDH1 mutations and a more differentiated phenotype. Out of eight glioma stem cell (GSC) lines, seven revealed positivity for the synaptic marker protein synaptophysin. Three had synapse-like structures identified by electron microscopy and were either vGlut1 (glutamatergic) or GAD67 (GABAergic) positive. In vivo, >10% synaptophysin-positive tumour cells were present in >90% of all gliomas. Synaptophysin expression was associated with proneural subtype and vGlut1 expression, suggesting that most synapse-like structures in glioma are glutamatergic. However, we found null associations between vGlut1 protein/mRNA expression and survival, GAS at onset, development of GAS after resection, and refractory GAS. Synapse-like structures were neither functional nor activated by spontaneous action potentials or cellular networks. Thus, aberrant neuronal differentiation including glutamatergic synapse-like structures is detectable in glioma but is associated neither with epileptic seizures nor with better survival.

AB - In order to design a painless and mechanically durable micro syringe-needle system for biomedical applications, the study of insect stingers is of interest because of their elegant structures and functionalities. In the present work, the structure, mechanical properties and the mechanical behavior during insertion of wasp and honeybee stingers have been investigated. The non-invasive imaging tool, micro-computed tomography has been employed to reveal the 3D-structures of wasp and honeybee stingers. A quasi-static nanoindentation instrument was used to measure the nanomechanical properties. Both wasp and honeybee stingers have graded mechanical properties, decreasing along their longitudinal direction starting from the base. The computed tomography images and the measured material properties from nanoindentation were fed into a computational framework to determine the mechanical behavior of the stingers during penetration. The computation results predicted the penetration angle of +10 degrees for the wasp stinger and -6 degrees for the honeybee stinger, which mimics the practical insertion mechanism of both stingers. Based on this understanding, a wasp and honeybee stringer inspired micro syringe-needle design has also been proposed. PMID- 30297702 TI - Elevated expression of a minor isoform of ANK3 is a risk factor for bipolar disorder. AB - Ankyrin-3 (ANK3) is one of the few genes that have been consistently identified as associated with bipolar disorder by multiple genome-wide association studies. However, the exact molecular basis of the association remains unknown. A rare loss-of-function splice-site SNP (rs41283526*G) in a minor isoform of ANK3 (incorporating exon ENSE00001786716) was recently identified as protective of bipolar disorder and schizophrenia. This suggests that an elevated expression of this isoform may be involved in the etiology of the disorders. In this study, we used novel approaches and data sets to test this hypothesis. First, we strengthen the statistical evidence supporting the allelic association by replicating the protective effect of the minor allele of rs41283526 in three additional large independent samples (meta-analysis p-values: 6.8E-05 for bipolar disorder and 8.2E-04 for schizophrenia). Second, we confirm the hypothesis that both bipolar and schizophrenia patients have a significantly higher expression of this isoform than controls (p-values: 3.3E-05 for schizophrenia and 9.8E-04 for bipolar type I). Third, we determine the transcription start site for this minor isoform by Pacific Biosciences sequencing of full-length cDNA and show that it is primarily expressed in the corpus callosum. Finally, we combine genotype and expression data from a large Norwegian sample of psychiatric patients and controls, and show that the risk alleles in ANK3 identified by bipolar disorder GWAS are located near the transcription start site of this isoform and are significantly associated with its elevated expression. Together, these results point to the likely molecular mechanism underlying ANK3's association with bipolar disorder. PMID- 30297701 TI - Blood-based biomarkers for Alzheimer disease: mapping the road to the clinic. AB - Biomarker discovery and development for clinical research, diagnostics and therapy monitoring in clinical trials have advanced rapidly in key areas of medicine - most notably, oncology and cardiovascular diseases - allowing rapid early detection and supporting the evolution of biomarker-guided, precision medicine-based targeted therapies. In Alzheimer disease (AD), breakthroughs in biomarker identification and validation include cerebrospinal fluid and PET markers of amyloid-beta and tau proteins, which are highly accurate in detecting the presence of AD-associated pathophysiological and neuropathological changes. However, the high cost, insufficient accessibility and/or invasiveness of these assays limit their use as viable first-line tools for detecting patterns of pathophysiology. Therefore, a multistage, tiered approach is needed, prioritizing development of an initial screen to exclude from these tests the high numbers of people with cognitive deficits who do not demonstrate evidence of underlying AD pathophysiology. This Review summarizes the efforts of an international working group that aimed to survey the current landscape of blood-based AD biomarkers and outlines operational steps for an effective academic-industry co-development pathway from identification and assay development to validation for clinical use. PMID- 30297703 TI - Biosynthetic energy cost for amino acids decreases in cancer evolution. AB - Rapidly proliferating cancer cells have much higher demand for proteinogenic amino acids than normal cells. The use of amino acids in human proteomes is largely affected by their bioavailability, which is constrained by the biosynthetic energy cost in living organisms. Conceptually distinct from gene based analyses, we introduce the energy cost per amino acid (ECPA) to quantitatively characterize the use of 20 amino acids during protein synthesis in human cells. By analyzing gene expression data from The Cancer Genome Atlas, we find that cancer cells evolve to utilize amino acids more economically by optimizing gene expression profile and ECPA shows robust prognostic power across many cancer types. We further validate this pattern in an experimental evolution of xenograft tumors. Our ECPA analysis reveals a common principle during cancer evolution.

PMID- 30297705 TI - beta2-Adrenergic receptor modulates mitochondrial metabolism and disease progression in recurrent/metastatic HPV(+) HNSCC. AB - The incidence of human papillomavirus-associated head and neck squamous cell carcinoma (HPV[ + ] HNSCC) is rapidly increasing. Although clinical management of primary HPV( + ) HNSCC is relatively successful, disease progression, including recurrence and metastasis, is often fatal. Moreover, patients with progressive disease face limited treatment options and significant treatment-associated morbidity. These clinical data highlight the need to identify targetable mechanisms that drive disease progression in HPV( + ) HNSCC to prevent and/or treat progressive disease. Interestingly, beta-adrenergic signaling has recently been associated with pro-tumor processes in several disease types. Here we show that an aggressive murine model of recurrent/metastatic HPV( + ) HNSCC upregulates beta2-adrenergic receptor (beta2AR) expression, concordant with significantly heightened mitochondrial metabolism, as compared with the parental model from which it spontaneously derived. beta-Adrenergic blockade effectively inhibits in vitro proliferation and migratory capacity in this model, effects associated with an attenuation of hyperactive mitochondrial respiration. Importantly, propranolol, a clinically available nonselective beta-blocker, significantly slows primary tumor growth, inhibits metastatic development, and shows additive benefit alongside standard-of-care modalities in vivo. Further, via CRISPR/Cas9 technology, we show that the hyperactive mitochondrial metabolic profile and aggressive in vivo phenotype of this recurrent/metastatic model are dependent on beta2AR expression. These data implicate beta2AR as a modulator of mitochondrial metabolism and disease progression in HPV( + ) HNSCC, and warrant further investigation into the use of beta-blockers as low cost, relatively tolerable, complementary treatment options in the clinical management of this disease. PMID- 30297706 TI - Transplantation of a bone marrow mesenchymal stem cell line increases neuronal progenitor cell migration in a cerebral ischemia animal model. AB - Mesenchymal stem cell (MSC) transplantation is demonstrated to improve functional and pathological recovery in cerebral ischemia. To understand the underlying mechanism, we transplanted a MSC line (B10) in a rat middle cerebral artery occlusion (MCAO) model and checked the proliferation and migration of neuronal progenitor cells (NPCs). B10 transplantation increased NPCs in the subventricular zone and their migration towards the lesion area at an earlier time. Fourteen days after MCAO, some NPCs were differentiated to neurons and astrocytes. Although B10 transplantation increased total number of both astrocytes and neurons, it only increased the differentiation of NPC to astrocyte. The mRNA of polysialylation enzyme ST8SiaIV and a chemokine SDF-1 were persistently increased in B10-transplanted groups. SDF-1-positive cell number was increased in the core and penumbra area, which was expressed in macrophage/microglia and transplanted B10 cells at 3 days after MCAO. Furthermore, SDF-1 mRNA expression in cell culture was high in B10 compared to a microglia (HMO) or a neuronal (A1) cell line. B10 culture supernatant increased in vitro A1 cell migration, which was significantly inhibited by siRNA-mediated SDF-1 silencing in B10. Thus, our results suggested that MSC transplantation increased endogenous NPC migration in cerebral ischemic condition by increasing chemokine and polysialylation enzyme expression, which could be helpful for the restorative management of cerebral ischemia. PMID- 30297707 TI - Maintaining and breaking symmetry in homomeric coiled-coil assemblies. AB - In coiled-coil (CC) protein structures alpha-helices wrap around one another to form rope-like assemblies. Most natural and designed CCs have two-four helices and cyclic (Cn) or dihedral (Dn) symmetry. Increasingly, CCs with five or more helices are being reported. A subset of these higher-order CCs is of interest as they have accessible central channels that can be functionalised; they are alpha helical barrels. These extended cavities are surprising given the drive to maximise buried hydrophobic surfaces during protein folding and assembly in water. Here, we show that alpha-helical barrels can be maintained by the strategic placement of beta-branched aliphatic residues lining the lumen. Otherwise, the structures collapse or adjust to give more-complex multi-helix assemblies without Cn or Dn symmetry. Nonetheless, the structural hallmark of CCs namely, knobs-into-holes packing of side chains between helices-is maintained leading to classes of CCs hitherto unobserved in nature or accessed by design. PMID- 30297708 TI - Sequencing HIV-neutralizing antibody exons and introns reveals detailed aspects of lineage maturation. AB - The developmental pathways of broadly neutralizing antibodies (bNAbs) against HIV are of great importance for the design of immunogens that can elicit protective responses. Here we show the maturation features of the HIV-neutralizing anti-V1V2 VRC26 lineage by simultaneously sequencing the exon together with the downstream intron of VRC26 members. Using the mutational landscapes of both segments and the selection-free nature of the intron region, we identify multiple events of amino acid mutational convergence in the complementarity-determining region 3 (CDR3) of VRC26 members, and determine potential intermediates with diverse CDR3s to a late stage bNAb from 2 years prior to its isolation. Moreover, we functionally characterize the earliest neutralizing intermediates with critical CDR3 mutations, with some emerging only 14 weeks after initial lineage detection and containing only ~6% V gene mutations. Our results thus underscore the utility of analyzing exons and introns simultaneously for studying antibody maturation and repertoire selection. PMID- 30297709 TI - Plantar cutaneous afferents influence the perception of Subjective Visual Vertical in quiet stance. AB - The estimation of Subjective Visual Vertical (SVV) involves the allocentric, gravitational and egocentric references, which are built by visual, vestibular and somatosensory afferents. Our goals were to assess the influence of plantar cutaneous afferents on the perception of SVV, and to see if there is a difference according to the efficiency of plantar cutaneous afferents. We recruited 48 young and healthy subjects and assessed their SVV and postural performances in quiet stance with a force platform, at 40 or 200 cm, in four ground conditions: on firm ground, on foam, with a bilateral, or with a unilateral 3 mm arch support. We also assessed the efficiency of our subjects' plantar afferents with the plantar quotient method and divided them in two groups: subjects with a normal use of plantar afferents and subjects with Plantar Exteroceptive Inefficiency (PEI). The results showed significant decreases in the counter clockwise SVV deviation only with the unilateral arch support, at near distance, and among the typically behaving subjects. We conclude that asymmetric foot cutaneous afferents are able to bias the egocentric vertical reference and hence influence the perception of SVV. This influence disappears among subjects with PEI, probably because of a distortion of the plantar signal.

PMID- 30297711 TI - Seasonal modulation of deep slow-slip and earthquakes on the Main Himalayan Thrust. AB - The interaction between seasonally-induced non-tectonic and tectonic deformation along the Himalayan plate boundary remains debated. Here, we propose that tectonic deformation along this plate boundary can be significantly influenced by the deformation induced by the non-tectonic hydrological loading cycles. We explore seasonal mass oscillations by continental water storage in Southeast Asia and Himalayan arc region using continuous Global Positioning System measurements and satellite data from the Gravity Recovery and Climate Experiment. We suggest that the substantially higher transient displacements above the base of the seismogenic zone indicate a role of changes in aseismic slip rate on the deep megathrust that may be controlled by seasonal hydrological loading. We invoke modulation of aseismic slip on the megathrust down-dip of the seismogenic zone due to a fault resonance process induced by the seasonal stress changes. This process modulates mid-crustal ramp associated micro-seismicity and influences the timing of Central Himalayan earthquakes. PMID- 30297712 TI - SWI/SNF catalytic subunits' switch drives resistance to EZH2 inhibitors in ARID1A mutated cells. AB - Inactivation of the subunits of SWI/SNF complex such as ARID1A is synthetically lethal with inhibition of EZH2 activity. However, mechanisms of de novo resistance to EZH2 inhibitors in cancers with inactivating SWI/SNF mutations are unknown. Here we show that the switch of the SWI/SNF catalytic subunits from SMARCA4 to SMARCA2 drives resistance to EZH2 inhibitors in ARID1A-mutated cells. SMARCA4 loss upregulates anti-apoptotic genes in the EZH2 inhibitor-resistant cells. EZH2 inhibitor-resistant ARID1A-mutated cells are hypersensitive to BCL2 inhibitors such as ABT263. ABT263 is sufficient to overcome resistance to an EZH2 inhibitor. In addition, ABT263 synergizes with an EZH2 inhibitor in vivo in ARID1A-inactivated ovarian tumor mouse models. Together, these data establish that the switch of the SWI/SNF catalytic subunits from SMARCA4 to SMARCA2 underlies the acquired resistance to EZH2 inhibitors. They suggest BCL2 inhibition alone or in combination with EZH2 inhibition represents urgently needed therapeutic strategy for ARID1A-mutated cancers. PMID- 30297713 TI - Adaptive effect of sericin on hepatic mitochondrial conformation through its regulation of apoptosis, autophagy and energy maintenance: a proteomics approach. AB - We recently demonstrated that in addition to its protective effect on pancreatic and adrenal biosynthesis, antioxidant properties of sericin decrease blood cholesterol levels and improve the liver mitochondrial architecture. However, little is known about the detailed mechanisms underlying these effects. Using proteomics and electron microscopy, we identified mitochondrial proteins that play important roles in the preservation of the mitochondrial ultrastructure and cholesterol-lowering properties of sericin. Our results showed that sericin maintains the mitochondrial architecture during conditions of high blood cholesterol by regulating apoptotic (NADH-ubiquinone oxidoreductase 75 kDa subunit) and autophagic (mitochondrial elongation factor Tu and prohibitin-2) proteins as well as energy maintenance proteins [haloacid dehalogenase-like hydrolase domain-containing protein 3, succinate dehydrogenase (ubiquinone) flavoprotein subunit, ATP synthase-alpha subunit precursor, enoyl-CoA hydratase domain-containing protein 3 and electron transfer flavoprotein subunit-alpha]. Sericin also exerts anti-oxidative properties via aconitate hydratase and Chain A, crystal structure of rat carnitine palmitoyltrasferase 2 proteins. Together, these activities may reduce hepatocytic triglyceride deposition, thereby decreasing steatosis, as demonstrated by the modulatory effects on ornithine aminotransferase, mitochondrial aspartate aminotransferase, acyl-CoA synthase, hydroxyacyl-CoA dehydrogenase and D-beta-hydroxybutyrate dehydrogenase. Sericin activity further balanced nitrogenous waste detoxification, characterised by carbamoyl-phosphate synthase (ammonia), aldehyde dehydrogenase and uricase, or folate biosynthesis via sarcosine dehydrogenase and dimethyl glycine dehydrogenase. These results suggest that sericin maintains the hepatic mitochondrial architecture through apoptotic, autophagic, energy maintenance and anti-oxidative mitochondrial proteins for alleviating hepatic steatosis and promoting liver function under conditions of hypercholesterolaemia.

AB - Repeated experiences may be integrated in succession during a learning process, or they may be combined as a whole within dedicated time windows to possibly promote quality control. Here we show that in Pavlovian, incremental and incidental learning, related information acquired within time windows of 5 h is combined to determine what mice learn. Trials required for learning had to occur within 5 h, when learning-related shared cues could produce association and interference. Upon acquisition, cFos expression was elevated during 5 h throughout specific system-wide neuronal assemblies. Time window function depended on network activity and cFos expression. Local cFos activity was required for distant assembly recruitment through network activity and distant BDNF. Activation of learning-related cFos assemblies was sufficient and necessary for time window function. Therefore, learning processes consist of dedicated 5 h time windows (time units for learning), involving maintenance of system-wide neuronal assemblies through network activity and cFos expression. PMID- 30297715 TI - Matrix mechanical plasticity regulates cancer cell migration through confining microenvironments. AB - Studies of cancer cell migration have found two modes: one that is protease independent, requiring micron-sized pores or channels for cells to squeeze through, and one that is protease-dependent, relevant for confining nanoporous matrices such as basement membranes (BMs). However, many extracellular matrices exhibit viscoelasticity and mechanical plasticity, irreversibly deforming in response to force, so that pore size may be malleable. Here we report the impact of matrix plasticity on migration. We develop nanoporous and BM ligand-presenting interpenetrating network (IPN) hydrogels in which plasticity could be modulated independent of stiffness. Strikingly, cells in high plasticity IPNs carry out protease-independent migration through the IPNs. Mechanistically, cells in high plasticity IPNs extend invadopodia protrusions to mechanically and plastically open up micron-sized channels and then migrate through them. These findings uncover a new mode of protease-independent migration, in which cells can migrate through confining matrix if it exhibits sufficient mechanical plasticity. PMID- 30297719 TI - Stable and unstable regions of the Lorenz system. AB - The stable and unstable regions of the Lorenz system are studied. We discuss the relationship between the initial conditions and both these regions, specifically, the preference for the trajectory of the Lorenz system to move towards the left or right equilibrium-point region from an initial point and the residence time of a trajectory in an equilibrium-point region. For this purpose, the four-rank Runge-Kutta algorithms and mathematical derivations are used, whereas a statistical method for the residence times is used. We conclude that the stable and unstable regions are intrinsic to the Lorenz system and have no correlation with the initial conditions; indeed, these regions do not change given different initial conditions. The trajectory of the Lorenz system tends towards the left equilibrium-point region locally, with an average residence time of 8.74 but only 5.789 for the right equilibrium-point region. In general, the system prefers the right equilibrium-point region for which the jump frequency of trajectories to the right region is 535 but only 465 to the left region from the initial conditions for the first time. PMID- 30297718 TI - Synergy between intrinsically disordered domains and structured proteins amplifies membrane curvature sensing. AB - The ability of proteins to sense membrane curvature is essential to cellular function. All known sensing mechanisms rely on protein domains with specific structural features such as wedge-like amphipathic helices and crescent-shaped BAR domains. Yet many proteins that contain these domains also contain large intrinsically disordered regions. Here we report that disordered domains are themselves potent sensors of membrane curvature. Comparison of Monte Carlo simulations with in vitro and live-cell measurements demonstrates that the polymer-like behavior of disordered domains found in endocytic proteins drives them to partition preferentially to convex membrane surfaces, which place fewer geometric constraints on their conformational entropy. Further, proteins containing both structured curvature sensors and disordered regions are more than twice as curvature sensitive as their respective structured domains alone. These findings demonstrate an entropic mechanism of curvature sensing that is independent of protein structure and illustrate how structured and disordered domains can synergistically enhance curvature sensitivity. PMID- 30297720 TI - Stable and discriminating features are predictive of cancer presence and Gleason grade in radical prostatectomy specimens: a multi-site study. AB - Site variation in fixation, staining, and scanning can confound automated tissue based image classifiers for disease characterization. In this study we incorporated stability into four feature selection methods for identifying the most robust and discriminating features for two prostate histopathology classification tasks. We evaluated 242 morphology features from N = 212 prostatectomy specimens from four sites for automated cancer detection and grading. We quantified instability as the rate of significant cross-site feature differences. We mapped feature stability and discriminability using 188 non cancerous and 210 cancerous regions via 3-fold cross validation, then held one site out, creating independent training and testing sets. In training, one feature set was selected only for discriminability, another for discriminability and stability. We trained a classifier with each feature set, testing on the hold out site. Experiments were repeated with 117 Gleason grade 3 and 112 grade 4 regions. Stability was calculated across non-cancerous regions. Gland shape features yielded the best stability and area under the receiver operating curve (AUC) trade-off while co-occurrence texture features were generally unstable. Our stability-informed method produced a cancer detection AUC of 0.98 +/- 0.05 and increased average Gleason grading AUC by 4.38%. Color normalization of the images tended to exacerbate feature instability. PMID- 30297721 TI - Visualising peripheral arterioles and venules through high-resolution and large area photoacoustic imaging. AB - Photoacoustic (PA) imaging (PAI) has been shown to be a promising tool for non invasive blood vessel imaging. A PAI system comprising a hemispherical detector array (HDA) has been reported previously as a method providing high morphological reproducibility. However, further improvements in diagnostic capability will require improving the image quality of PAI and fusing functional and morphological imaging. Our newly developed PAI system prototype not only enhances the PA image resolution but also acquires ultrasonic (US) B-mode images at continuous positions in the same coordinate axes. In addition, the pulse-to-pulse alternating laser irradiation shortens the measurement time difference between two wavelengths. We scanned extremities and breasts in an imaging region 140 mm in diameter and obtained 3D-PA images of fine blood vessels, including arterioles and venules. We could estimate whether a vessel was an artery or a vein by using the S-factor obtained from the PA images at two wavelengths, which corresponds approximately to the haemoglobin oxygen saturation. Furthermore, we observed tumour-related blood vessels around breast tumours with unprecedented resolution. In the future, clinical studies with our new PAI system will help to elucidate various mechanisms of vascular-associated diseases and events. PMID- 30297722 TI - Ginkgolide B promotes neuronal differentiation through the Wnt/beta-catenin pathway in neural stem cells of the postnatal mammalian subventricular zone. AB - Chinese herbal medicines (CHMs) have been used to treat human diseases for thousands of years. Among them, Ginkgo biloba is reported to be beneficial to the nervous system and a potential treatment of neurological disorders. Since the presence of adult neural stem cells (NSCs) brings hope that the brain may heal itself, whether the effect of Ginkgo biloba is on NSCs remains elusive. In this study, we found that Ginkgo biloba extract (GBE) and one of its main ingredients, ginkgolide B (GB) promoted cell cycle exit and neuronal differentiation in NSCs derived from the postnatal subventricular zone (SVZ) of the mouse lateral ventricle. Furthermore, the administration of GB increased the nuclear level of beta-catenin and activated the canonical Wnt pathway. Knockdown of beta-catenin blocked the neurogenic effect of GB, suggesting that GB promotes neuronal differentiation through the Wnt/beta-catenin pathway. Thus, our data provide a potential mechanism underlying the therapeutic effect of GBE or GB on brain injuries and neurodegenerative disorders. PMID- 30297723 TI - Chromosome replication as a measure of bacterial growth rate during Escherichia coli infection in the mouse peritonitis model. AB - The efficacy of most antibiotics is dependent on active bacterial growth, yet little is known about the growth dynamics during infection. Therefore, means to measure in-host bacterial growth rate is of importance. Here, we use chromosome replication as readout for in situ bacterial growth rate during infection; obtained from a single biological specimen. We have applied two independent methods: quantitative PCR (qPCR) and fluorescence microscopy, to quantify the level of chromosome replication present during Escherichia coli propagation in the mouse peritonitis model. We find that the methods complement each other and allow for quantification of growth rate, both on a population average and on a single-cell level. We demonstrate the presence of heterogeneous growth rates within bacterial populations propagating during infection. Also, no growth cessation was observed during the apparent stationary phase in vivo, and, by comparison of growth dynamics at different anatomical sites, we demonstrate that E. coli is unlikely to grow independently intravascularly. These findings provide novel insight into bacterial growth during host infection, and underscore the importance of pinpointing the primary site of infection in septicaemia of unknown origin and ensuring antibiotic availability at this site. PMID- 30297724 TI - Clinical usefulness of C-reactive protein to albumin ratio in predicting 30-day mortality in critically ill patients: A retrospective analysis. AB - This study aimed to examine the prognostic value of C-reactive protein (CRP)/albumin (ALB) ratio among patients who were admitted to the intensive care unit (ICU) in predicting 30-day mortality rate. This retrospective cohort study was conducted by examining the medical records of adult patients who were admitted to the ICU at Seoul National University Bundang Hospital between 1 January 2012 and 31 December 2016. Data from 6,972 individuals were included in the final analysis, and 547 of these individuals (7.1%) died within 30 days after their ICU admission. The multivariable Cox regression analysis revealed that an increase of 1 for the CRP/ALB ratio was associated with an 11% increase in the risk of 30-day mortality (hazard ratio: 1.11, 95% confidence interval: 1.09-1.14, P < 0.001). However, the area under curve of CRP/ALB ratio in receiver operating characteristic analysis was lower than that of Acute Physiologic Assessment and Chronic Health Evaluation (APACHE) II, Charlson comorbidity index, or serum albumin alone. Although an elevated CRP/ALB ratio on ICU admission was an independent risk factor for 30-day mortality rate, the predictive power of CRP/ALB ratio was lower than that of albumin alone, APACHE II, and Charlson comorbidity index.

AB - Two members of 6-cysteine (6-cys) protein family, P48/45 and P230, are important for gamete fertility in rodent and human malaria parasites and are leading transmission blocking vaccine antigens. Rodent and human parasites encode a paralog of P230, called P230p. While P230 is expressed in male and female parasites, P230p is expressed only in male gametocytes and gametes. In rodent malaria parasites this protein is dispensable throughout the complete life-cycle; however, its function in P. falciparum is unknown. Using CRISPR/Cas9 methodology we disrupted the gene encoding Pfp230p resulting in P. falciparum mutants (PfDeltap230p) lacking P230p expression. The PfDeltap230p mutants produced normal numbers of male and female gametocytes, which retained expression of P48/45 and P230. Upon activation male PfDeltap230p gametocytes undergo exflagellation and form male gametes. However, male gametes are unable to attach to red blood cells resulting in the absence of characteristic exflagellation centres in vitro. In the absence of P230p, zygote formation as well as oocyst and sporozoite development were strongly reduced (>98%) in mosquitoes. These observations demonstrate that P230p, like P230 and P48/45, has a vital role in P. falciparum male fertility and zygote formation and warrants further investigation as a potential transmission blocking vaccine candidate. PMID- 30297726 TI - Baseline resistance-guided therapy does not enhance the response to interferon free treatment of HCV infection in real life. AB - Hepatitis C virus (HCV) response to direct-acting antivirals (DAAs) may be influenced by the presence of resistance-associated substitutions (RASs). This study aimed to assess if NS5A baseline RAS-guided treatment enhances the rate of sustained viral response (SVR) in naive HCV-infected patients in clinical practice. All HCV-infected patients who initiated treatment with interferon (IFN) free DAA-based regimens between March 2016 and May 2017 in 17 Spanish hospitals and who had evaluable SVR 12 weeks (SVR12) after the end of therapy were included. Patients had to be DAA naive, with the exception of sofosbuvir with/without IFN. In one hospital, participants received therapy guided by the presence of NS5A-RASs (RGT population). Patients enrolled in the remaining hospitals, without baseline RASs testing, constituted the control population. A total of 120 and 512 patients were included in the RGT and control populations, respectively. Nine (7.5%) individuals in the RGT population showed baseline NS5A RASs. All of them achieved SVR12. The SVR12 rate in the RGT population was 97.2% (three relapses) whereas it was 98.8% (six relapses) in the control population (p = 0.382). Our findings suggest that testing for baseline NS5A-RASs in naive HCV infected patients does not enhance the rate of SVR to DAA-based IFN-free therapy in clinical practice. PMID- 30297728 TI - Impact of the Coal Mining on the Spatial Distribution of Potentially Toxic Metals in Farmland Tillage Soil. AB - Coal mining areas are prone to hazardous element contamination because of mining activities and the resulting wastes, mainly including Cr, Ni, Cu, Zn, Cd and Pb. This study collected 103 samples of farmland tillage soil surrounding a coal mine in southwestern Shandong province and monitored the heavy metal concentrations of each sample by inductively coupled plasma mass spectrometer (ICP-MS). Statistics, geostatistics, and geographical information systems (GIS) were used to determine the spatial pattern of the potentially toxic metals above in the coal mining area. The results show that the toxic metal concentrations have wide ranges, but the average values for Cr, Ni, Cu, Zn, Cd and Pb are 72.16, 29.53, 23.07, 66.30, 0.14 and 23.71 mg Kg-1, which mostly exceed the natural soil background contents of Shandong Province. The element pairs Ni-Cu, Ni-Zn, and Cu-Zn have relatively high correlation coefficients (0.805, 0.505, 0.613, respectively). The Kriging interpolation results show that the contents of soil toxic metals are influenced by coal mining activities. Moreover, micro-domain variation analysis revealed the toxic metals in the typical area of the coal transportation line. These findings offer systematic insight into the influence of coal mining activities on toxic metals in farmland tillage soil. PMID- 30297727 TI - Galanin neurons in the ventrolateral preoptic area promote sleep and heat loss in mice. AB - The preoptic area (POA) is necessary for sleep, but the fundamental POA circuits have remained elusive. Previous studies showed that galanin (GAL)- and GABA producing neurons in the ventrolateral preoptic nucleus (VLPO) express cFos after periods of increased sleep and innervate key wake-promoting regions. Although lesions in this region can produce insomnia, high frequency photostimulation of the POAGAL neurons was shown to paradoxically cause waking, not sleep. Here we report that photostimulation of VLPOGAL neurons in mice promotes sleep with low frequency stimulation (1-4 Hz), but causes conduction block and waking at frequencies above 8 Hz. Further, optogenetic inhibition reduces sleep. Chemogenetic activation of VLPOGAL neurons confirms the increase in sleep, and also reduces body temperature. In addition, chemogenetic activation of VLPOGAL neurons induces short-latency sleep in an animal model of insomnia. Collectively, these findings establish a causal role of VLPOGAL neurons in both sleep induction and heat loss. PMID- 30297730 TI - Preparation of NiAl2O4-Based Flexible Substrates for Metamaterials with Negative Dielectric Properties. AB - Various techniques are commonly used to produce nano-crystalline NiAl2O4 materials; however, their practical applications in the microwave region remain very limited. In this work, flexible substrates for metamaterials containing two different concentrations of NiAl2O4 (labelled Ni36 and Ni42) have been synthesised using a sol-gel method. The formation of spinel structures in the synthesised materials is confirmed, and their crystalline sizes are determined using scanning electron microscopy, X-ray diffraction, and energy dispersive X ray techniques. The dielectric properties, conductivities, loss tangents, and other parameters of the NiAl2O4-based substrates are analysed to evaluate their applicability as dielectric materials for the microwave frequency range. The obtained results show that the fabricated Ni36 and Ni42 nickel aluminates possess dielectric constants of 4.94 and 4.97 and loss tangents of 0.01 and 0.007, respectively; in addition, they exhibit high flexibility and light weight, which make them suitable for applications as metamaterial substrates. The synthesised structures are also validated experimentally using a commercially available electromagnetic simulator; as a result, double negative behaviour of the flexible metamaterials has been observed. Furthermore, it is found that the prepared NiAl2O4 substrates can be used in the S-, C-, and X-bands of the microwave frequency region. PMID- 30297729 TI - Identification of novel acetylcholinesterase inhibitors designed by pharmacophore based virtual screening, molecular docking and bioassay. AB - In this study, pharmacophore based 3D QSAR models for human acetylcholinesterase (AChE) inhibitors were generated, with good significance, statistical values (r2training = 0.73) and predictability (q2training = 0.67). It was further validated by three methods (Fischer's test, decoy set and Guner-Henry scoring method) to show that the models can be used to predict the biological activities of compounds without costly and time-consuming synthesis. The criteria for virtual screening were also validated by testing the selective AChE inhibitors. Virtual screening experiments and subsequent in vitro evaluation of promising hits revealed a novel and selective AChE inhibitor. Thus, the findings reported herein may provide a new strategy for the discovery of selective AChE inhibitors. The IC50 value of compounds 5c and 6a presented selective inhibition of AChE without inhibiting butyrylcholinesterase (BChE) at uM level. Molecular docking studies were performed to explain the potent AChE inhibition of the target compounds studies to explain high affinity. PMID- 30297732 TI - Sulphide Re-Os geochronology links orogenesis, salt and Cu-Co ores in the Central African Copperbelt. AB - The origin of giant, sedimentary rock-hosted copper-cobalt (Cu-Co) provinces remains contentious, in part due to the lack of precise and reliable ages for mineralisation. As such, no consensus has been reached on the genetic model for ore formation, and the relationships between tectonism, palaeo-fluid circulation and mineralisation. Here, we link the timing of Cu-Co mineralisation in the Central African Copperbelt to compressional tectonics during the Lufilian Orogeny by using new ca. 609-473 Ma ages given by rhenium-osmium (Re-Os) isotope data for individual Cu-Co sulphides (carrolite and bornite) from the Cu-Co Kamoto deposit. The initial Os isotope composition of carrolite is compatible with the leaching of Os and Cu(-Co) from Mesoproterozoic Cu sulphide deposits hosted in fertile basement. In contrast, the ca. 473 Ma Cu-Au mineralisation stage, which is coeval with late- to post-compressional deformation, may be a distal expression of fluid flow and heat transfer caused by magmatic intrusions in the core of the collisional orogen. The Re-Os ages support a model for mineralisation driven by evaporite dissolution and percolation of large volumes of dense brines in the Katangan Basin during the Lufilian Orogeny. PMID- 30297731 TI - Incidence of notified Lyme borreliosis in Germany, 2013-2017. AB - Lyme borreliosis (LB) is the most commonly reported tick-borne disease in Germany. In 9/16 states, notification of erythema migrans (EM), acute neuroborreliosis (NB) and Lyme arthritis (LA) is mandatory. We describe incidence measures, time trends, geographical distribution and frequencies of manifestations to better understand LB epidemiology and target prevention measures. We used cases notified in the 9 states and confirmed by local health offices, 2013-2017, to calculate incidences by time, place and person. Altogether, we observed 56,446 cases. Disease onset peaked yearly in July. Incidence ranged from 26/100,000 (2015) to 41/100,000 (2013) with mean annual incidences 2013-2017 on district level between 0.5/100,000 and 138/100,000. Median age was 54 years with peaks in boys (5-9 years, mean incidence 36/100,000) and women (50-69 years, mean incidence 57/100,000). 95% experienced EM only, 2.7% NB and 2.1% LA. 54% were female, but more men had NB (56%) and LA (53%, p < 0.001). Hospitalisation was recorded for 10% of LA and 71% of NB cases. LB remains an important public health concern in Germany with marked regional variation. To facilitate early diagnosis and treatment, health authorities should raise awareness among physicians and promote prevention strategies among the general population: tick-bite-protection, prompt tick removal and medical consultation. PMID- 30297734 TI - Hanbury-Brown and Twiss exchange and non-equilibrium-induced correlations in disordered, four-terminal graphene-ribbon conductor. AB - We have investigated current-current correlations in a cross-shaped conductor made of graphene. The mean free path of charge carriers is on the order of the ribbon width which leads to a hybrid conductor where there is diffusive transport in the device arms while the central connection region displays near ballistic transport. Our data on auto and cross correlations deviate from the predictions of Landauer-Buttiker theory, and agreement can be obtained only by taking into account contributions from non-thermal electron distributions at the inlets to the semiballistic center, in which the partition noise becomes strongly modified. The experimental results display distinct Hanbury - Brown and Twiss (HBT) exchange correlations, the strength of which is boosted by the non-equilibrium occupation-number fluctuations internal to this hybrid conductor. Our work demonstrates that variation in electron coherence along atomically-thin, two dimensional conductors has significant implications on their noise and cross correlation properties. PMID- 30297733 TI - Computational B-cell epitope identification and production of neutralizing murine antibodies against Atroxlysin-I. AB - Epitope identification is essential for developing effective antibodies that can detect and neutralize bioactive proteins. Computational prediction is a valuable and time-saving alternative for experimental identification. Current computational methods for epitope prediction are underused and undervalued due to their high false positive rate. In this work, we targeted common properties of linear B-cell epitopes identified in an individual protein class (metalloendopeptidases) and introduced an alternative method to reduce the false positive rate and increase accuracy, proposing to restrict predictive models to a single specific protein class. For this purpose, curated epitope sequences from metalloendopeptidases were transformed into frame-shifted Kmers (3 to 15 amino acid residues long). These Kmers were decomposed into a matrix of biochemical attributes and used to train a decision tree classifier. The resulting prediction model showed a lower false positive rate and greater area under the curve when compared to state-of-the-art methods. Our predictions were used for synthesizing peptides mimicking the predicted epitopes for immunization of mice. A predicted linear epitope that was previously undetected by an experimental immunoassay was able to induce neutralizing-antibody production in mice. Therefore, we present an improved prediction alternative and show that computationally identified epitopes can go undetected during experimental mapping. PMID- 30297735 TI - Attenuation of hypertension by C-fiber stimulation of the human median nerve and the concept-based novel device. AB - High blood pressure (BP) is a highly controllable risk factor for cardiovascular diseases; however, awareness of this condition and the rates of controlled hypertension are low. Experimental animal studies have shown that stimulation of the median nerve or PC6 acupoint over the wrist has effects on cardiovascular activities, including reductions in systolic and diastolic BPs. A proof-of concept study was conducted in humans to investigate whether stimulation of median nerve near PC6 acupoint decreased high BP, identify the optimal stimulation parameters for the BP-lowering effects of median nerve stimulation, and determine the specific peripheral nerves or types of afferent fibers mediating the BP-lowering effects. Median nerve stimulation was carried out bilaterally or unilaterally with different stimulation parameters, and the BP and heart rate were monitored. The afferent mechanisms underlying the effects of median nerve stimulation on hypertension were investigated via microneurography, A-fiber blocking experiments, and localized chemical or electrical stimulation. Bilateral median nerve stimulation at either low or high frequencies produced profound but transient reductions in systolic BP, which were elicited when median nerve stimulation was unilaterally applied at interelectrode distances of 2 and 4 cm. Systolic BP was also reduced by electrical stimulation of the thumb on the palm side. Although microneurographic recordings revealed the excitation of both A- and C-fibers following median nerve stimulation, the median nerve-mediated reductions in BP were not affected by A-fiber blockade, and they were mimicked by the activation of C-fibers with capsaicin. The present results indicate that activation of C-fibers in the median nerve generates BP-lowering effects in humans. Based on our clinical study, an optimized median nerve stimulator was built and combined with a wrist BP monitor for simultaneous BP measurements and median nerve stimulation.

PMID- 30297736 TI - Probing the origin of matching functional jaws: roles of Dlx5/6 in cranial neural crest cells. AB - Gnathostome jaws derive from the first pharyngeal arch (PA1), a complex structure constituted by Neural Crest Cells (NCCs), mesodermal, ectodermal and endodermal cells. Here, to determine the regionalized morphogenetic impact of Dlx5/6 expression, we specifically target their inactivation or overexpression to NCCs. NCC-specific Dlx5/6 inactivation (NCC?Dlx5/6) generates severely hypomorphic lower jaws that present typical maxillary traits. Therefore, differently from Dlx5/6 null-embryos, the upper and the lower jaws of NCC?Dlx5/6 mice present a different size. Reciprocally, forced Dlx5 expression in maxillary NCCs provokes the appearance of distinct mandibular characters in the upper jaw. We conclude that: (1) Dlx5/6 activation in NCCs invariably determines lower jaw identity; (2) the morphogenetic processes that generate functional matching jaws depend on the harmonization of Dlx5/6 expression in NCCs and in distinct ectodermal territories. The co-evolution of synergistic opposing jaws requires the coordination of distinct regulatory pathways involving the same transcription factors in distant embryonic territories. PMID- 30297739 TI - ROS-induced R loops trigger a transcription-coupled but BRCA1/2-independent homologous recombination pathway through CSB. AB - Actively transcribed regions of the genome are protected by transcription-coupled DNA repair mechanisms, including transcription-coupled homologous recombination (TC-HR). Here we used reactive oxygen species (ROS) to induce and characterize TC HR at a transcribed locus in human cells. As canonical HR, TC-HR requires RAD51. However, the localization of RAD51 to damage sites during TC-HR does not require BRCA1 and BRCA2, but relies on RAD52 and Cockayne Syndrome Protein B (CSB). During TC-HR, RAD52 is recruited by CSB through an acidic domain. CSB in turn is recruited by R loops, which are strongly induced by ROS in transcribed regions. Notably, CSB displays a strong affinity for DNA:RNA hybrids in vitro, suggesting that it is a sensor of ROS-induced R loops. Thus, TC-HR is triggered by R loops, initiated by CSB, and carried out by the CSB-RAD52-RAD51 axis, establishing a BRCA1/2-independent alternative HR pathway protecting the transcribed genome. PMID- 30297741 TI - Collapse of genetic division of labour and evolution of autonomy in pellicle biofilms. AB - Closely related microorganisms often cooperate, but the prevalence and stability of cooperation between different genotypes remain debatable. Here, we track the evolution of pellicle biofilms formed through genetic division of labour and ask whether partially deficient partners can evolve autonomy. Pellicles of Bacillus subtilis rely on an extracellular matrix composed of exopolysaccharide (EPS) and the fibre protein TasA. In monocultures, ?eps and ?tasA mutants fail to form pellicles, but, facilitated by cooperation, they succeed in co-culture. Interestingly, cooperation collapses on an evolutionary timescale and ?tasA gradually outcompetes its partner ?eps. Pellicle formation can evolve independently from division of labour in ?eps and ?tasA monocultures, by selection acting on the residual matrix component, TasA or EPS, respectively. Using a set of interdisciplinary tools, we unravel that the TasA producer (?eps) evolves via an unconventional but reproducible substitution in TasA that modulates the biochemical properties of the protein. Conversely, the EPS producer (DeltatasA) undergoes genetically variable adaptations, all leading to enhanced EPS secretion and biofilms with different biomechanical properties. Finally, we revisit the collapse of division of labour between Deltaeps and DeltatasA in light of a strong frequency versus exploitability trade-off that manifested in the solitarily evolving partners. We propose that such trade-off differences may represent an additional barrier to evolution of division of labour between genetically distinct microorganisms. PMID- 30297740 TI - Primate immunodeficiency virus proteins Vpx and Vpr counteract transcriptional repression of proviruses by the HUSH complex. AB - Host factors that silence provirus transcription in CD4+ memory T cells help HIV 1 escape eradication by the host immune system and by antiviral drugs1. These same factors, however, must be overcome for HIV-1 to propagate. Here we show that Vpx and Vpr encoded by diverse primate immunodeficiency viruses activate provirus transcription. Vpx and Vpr are adaptor proteins for the DCAF1-CUL4A/B E3 ubiquitin ligase that degrade SAMHD1 and increase reverse transcription2-4. Nonetheless, Vpx and Vpr have effects on reporter gene expression that are not explained by SAMHD1 degradation5-8. A screen for factors that mimic these effects identified the human silencing hub (HUSH) complex, FAM208A (TASOR/RAP140), MPHOSPH8 (MPP8), PPHLN1 (PERIPHILIN) and MORC29-13. Vpx associated with the HUSH complex and decreased steady-state level of these proteins in a DCAF1/CUL4A/B/proteasome-dependent manner14,15. Replication kinetics of HIV-1 and SIVMAC was accelerated to a similar extent by vpx or FAM208A knockdown. Finally, vpx increased steady-state levels of LINE-1 ORF1p, as previously described for FAM208A disruption11. These results demonstrate that the HUSH complex represses primate immunodeficiency virus transcription, and that, to counteract this restriction, viral Vpx or Vpr proteins degrade the HUSH complex. PMID- 30297742 TI - Leveraging single-cell genomics to expand the fungal tree of life. AB - Environmental DNA surveys reveal that most fungal diversity represents uncultured species. We sequenced the genomes of eight uncultured species across the fungal tree of life using a new single-cell genomics pipeline. We show that, despite a large variation in genome and gene space recovery from each single amplified genome (SAG), >=90% can be recovered by combining multiple SAGs. SAGs provide robust placement for early-diverging lineages and infer a diploid ancestor of fungi. Early-diverging fungi share metabolic deficiencies and show unique gene expansions correlated with parasitism and unculturability. Single-cell genomics holds great promise in exploring fungal diversity, life cycles and metabolic potential. PMID- 30297744 TI - Coexistence theory and the frequency-dependence of priority effects. AB - Priority effects are commonly used to describe a broad suite of phenomena capturing the influence of species arrival order on the diversity, composition and function of ecological communities. Several studies have suggested reframing priority effects around the stabilizing and equalizing concepts of coexistence theory. We show that the only compatible priority effects are those characterized by positive frequency-dependence, irrespective of whether they emerge in equilibrium or non-equilibrium systems. PMID- 30297743 TI - Hyaluronic acid-CD44 interactions promote BMP4/7-dependent Id1/3 expression in melanoma cells. AB - BMP4/7-dependent expression of inhibitor of differentiation/DNA binding (Id) proteins 1 and 3 has been implicated in tumor progression and poor prognosis of malignant melanoma patients. Hyaluronic acid (HA), a pericellular matrix component, supports BMP7 signalling in murine chondrocytes through its receptor CD44. However, its role in regulating BMP signalling in melanoma is not clear. In this study we found that depletion of endogenously-produced HA by hyaluronidase treatment or by inhibition of HA synthesis by 4-methylumbelliferone (4-MU) resulted in reduced BMP4/7-dependent Id1/3 protein expression in mouse melanoma B16-F10 and Ret cells. Conversely, exogenous HA treatment increased BMP4/7 dependent Id1/3 protein expression. Knockdown of CD44 reduced BMP4/7-dependent Id1/3 protein expression, and attenuated the ability of exogenous HA to stimulate Id1 and Id3 expression in response to BMP. Co-IP experiments demonstrated that CD44 can physically associate with the BMP type II receptor (BMPR) ACVR2B. Importantly, we found that coordinate expression of Id1 or Id3 with HA synthases HAS2, HAS3, and CD44 is associated with reduced overall survival of cutaneous melanoma patients. Our results suggest that HA-CD44 interactions with BMPR promote BMP4/7-dependent Id1/3 protein expression in melanoma, contributing to reduced survival in melanoma patients. PMID- 30297746 TI - Brian Maurer (1954-2018). PMID- 30297745 TI - Shark genomes provide insights into elasmobranch evolution and the origin of vertebrates. AB - Modern cartilaginous fishes are divided into elasmobranchs (sharks, rays and skates) and chimaeras, and the lack of established whole-genome sequences for the former has prevented our understanding of early vertebrate evolution and the unique phenotypes of elasmobranchs. Here we present de novo whole-genome assemblies of brownbanded bamboo shark and cloudy catshark and an improved assembly of the whale shark genome. These relatively large genomes (3.8-6.7 Gbp) contain sparse distributions of coding genes and regulatory elements and exhibit reduced molecular evolutionary rates. Our thorough genome annotation revealed Hox C genes previously hypothesized to have been lost, as well as distinct gene repertories of opsins and olfactory receptors that would be associated with adaptation to unique underwater niches. We also show the early establishment of the genetic machinery governing mammalian homoeostasis and reproduction at the jawed vertebrate ancestor. This study, supported by genomic, transcriptomic and epigenomic resources, provides a foundation for the comprehensive, molecular exploration of phenotypes unique to sharks and insights into the evolutionary origins of vertebrates. PMID- 30297747 TI - Adaptive transcription-splicing resynchronization upon losing an essential splicing factor. AB - Essential genes form the core of a genome and are therefore thought to be indispensable for cellular viability. However, recent findings have challenged this notion in that cells may survive in the absence of some essential genes provided that relevant genetic modifiers are in existence. We therefore hypothesized that the loss of an essential gene may not always be fatefully detrimental; instead, it may pave the way towards genome evolution. We experimentally tested this hypothesis in the context of pre-messenger RNA splicing by evolving yeast cells harbouring a permanent loss of the essential splicing factor Prp28 in the presence of a genetic modifier. Here, we show that cellular fitness can be restored by compensatory mutations that alter either the splicing machinery per se or the Spt-Ada-Gcn5 acetyltransferase transcription co activator complex in the cells with no Prp28. Biochemical and genetic analysis revealed that slowing down transcription compensates for splicing deficiency, which in turn boosts cellular fitness. In addition, we found that inefficient splicing also conversely decreases nascent RNA production. Taken together, our data suggest that transcription-splicing synchronization contributes to robustness in the gene-expression pathway and argue that the intrinsic interconnectivity within a biological system can be exploited for compensatory evolution and system re-optimization. PMID- 30297748 TI - Early neurogenomic response associated with variation in guppy female mate preference. AB - Understanding the evolution of mate choice requires dissecting the mechanisms of female preference, particularly how these differ among social contexts and preference phenotypes. Here, we studied the female neurogenomic response after only 10 min of mate exposure in both a sensory component (optic tectum) and a decision-making component (telencephalon) of the brain. By comparing the transcriptional response between females with and without preferences for colourful males, we identified unique neurogenomic elements associated with the female preference phenotype that are not present in females without preference. A network analysis revealed different properties for this response at the sensory processing and the decision-making levels, and we show that this response is highly centralized in the telencephalon. Furthermore, we identified an additional set of genes that vary in expression across social contexts, beyond mate evaluation. We show that transcription factors among these loci are predicted to regulate the transcriptional response of the genes we found to be associated with female preference. PMID- 30297749 TI - Functional shifts in microbial mats recapitulate early Earth metabolic transitions. AB - Phototrophic microbial mats dominated terrestrial ecosystems for billions of years, largely causing, through cyanobacterial oxygenic photosynthesis, but also undergoing, the Great Oxidation Event approximately 2.5 billion years ago. Taking a space-for-time approach based on the universality of core metabolic pathways expressed at ecosystem level, we studied gene content and co-occurrence networks in high-diversity metagenomes from spatially close microbial mats along a steep redox gradient. The observed functional shifts suggest that anoxygenic photosynthesis was present but not predominant under early Precambrian conditions, being accompanied by other autotrophic processes. Our data also suggest that, in contrast to general assumptions, anoxygenic photosynthesis largely expanded in parallel with the subsequent evolution of oxygenic photosynthesis and aerobic respiration. Finally, our observations might represent space-for-time evidence that the Wood-Ljungdahl carbon fixation pathway dominated phototrophic mats in early ecosystems, whereas the Calvin cycle probably evolved from pre-existing variants before becoming the dominant contemporary form of carbon fixation. PMID- 30297751 TI - Catalytic dehydrogenative decarboxyolefination of carboxylic acids. AB - Alkenes are among the most versatile building blocks and are widely used for the production of polymers, detergents and synthetic lubricants. Currently, alkenes are sourced from petroleum feedstocks such as naphtha. In light of the necessity to invent sustainable production methods, multiple approaches to making alkenes from abundant fatty acids have been evaluated. However, all attempts so far have required at least one stoichiometric additive, which is an obstruction for applications at larger scales. Here, we report an approach to making olefins from carboxylic acids, in which every additional reaction constituent can be used as a catalyst. We show how abundant fatty acids can be converted to alpha-olefins, and expand the method to include structurally complex carboxylic acids, giving access to synthetically versatile intermediates. Our approach is enabled by the cooperative interplay between a cobalt catalyst, which functions as a proton reduction catalyst, and a photoredox catalyst, which mediates oxidative decarboxylation; coupling both processes enables catalytic conversion of carboxylic acids to olefins. PMID- 30297750 TI - Inhibiting amyloid-beta cytotoxicity through its interaction with the cell surface receptor LilrB2 by structure-based design. AB - Inhibiting the interaction between amyloid-beta (Abeta) and a neuronal cell surface receptor, LilrB2, has been suggested as a potential route for treating Alzheimer's disease. Supporting this approach, Alzheimer's-like symptoms are reduced in mouse models following genetic depletion of the LilrB2 homologue. In its pathogenic, oligomeric state, Abeta binds to LilrB2, triggering a pathway to synaptic loss. Here we identify the LilrB2 binding moieties of Abeta (16KLVFFA21) and identify its binding site on LilrB2 from a crystal structure of LilrB2 immunoglobulin domains D1D2 complexed to small molecules that mimic phenylalanine residues. In this structure, we observed two pockets that can accommodate the phenylalanine side chains of KLVFFA. These pockets were confirmed to be 16KLVFFA21 binding sites by mutagenesis. Rosetta docking revealed a plausible geometry for the Abeta-LilrB2 complex and assisted with the structure-guided selection of small molecule inhibitors. These molecules inhibit Abeta-LilrB2 interactions in vitro and on the cell surface and reduce Abeta cytotoxicity, which suggests these inhibitors are potential therapeutic leads against Alzheimer's disease. PMID- 30297753 TI - Cavitation energies can outperform dispersion interactions. AB - The accurate dissection of binding energies into their microscopic components is challenging, especially in solution. Here we study the binding of noble gases (He Xe) with the macrocyclic receptor cucurbit[5]uril in water by displacement of methane and ethane as 1H NMR probes. We dissect the hydration free energies of the noble gases into an attractive dispersive component and a repulsive one for formation of a cavity in water. This allows us to identify the contributions to host-guest binding and to conclude that the binding process is driven by differential cavitation energies rather than dispersion interactions. The free energy required to create a cavity to accept the noble gas inside the cucurbit[5]uril is much lower than that to create a similarly sized cavity in bulk water. The recovery of the latter cavitation energy drives the overall process, which has implications for the refinement of gas-storage materials and the understanding of biological receptors. PMID- 30297752 TI - Mining the cellular inventory of pyridoxal phosphate-dependent enzymes with functionalized cofactor mimics. AB - Pyridoxal phosphate (PLP) is an enzyme cofactor required for the chemical transformation of biological amines in many central cellular processes. PLP dependent enzymes (PLP-DEs) are ubiquitous and evolutionarily diverse, making their classification based on sequence homology challenging. Here we present a chemical proteomic method for reporting on PLP-DEs using functionalized cofactor probes. We synthesized pyridoxal analogues modified at the 2'-position, which are taken up by cells and metabolized in situ. These pyridoxal analogues are phosphorylated to functional cofactor surrogates by cellular pyridoxal kinases and bind to PLP-DEs via an aldimine bond which can be rendered irreversible by NaBH4 reduction. Conjugation to a reporter tag enables the subsequent identification of PLP-DEs using quantitative, label-free mass spectrometry. Using these probes we accessed a significant portion of the Staphylococcus aureus PLP DE proteome (73%) and annotate uncharacterized proteins as novel PLP-DEs. We also show that this approach can be used to study structural tolerance within PLP-DE active sites and to screen for off-targets of the PLP-DE inhibitor D-cycloserine.

AB - A prerequisite to gain a complete understanding of the most basic aspects of chemical reactions is the ability to perform experiments with complete control over the reactant degrees of freedom. By controlling these, details of a reaction mechanism can be investigated and ultimately manipulated. Here, we present a study of chemi-ionization-a fundamental energy-transfer reaction-under completely controlled conditions. The collision energy of the reagents was tuned from 0.02 K to 1,000 K, with the orientation of the excited Ne atom relative to Ar fully specified by an external magnetic field. Chemi-ionization of Ne(3P2) and Ar in these conditions enables a detailed investigation of how the reaction proceeds, and provides us with a means to control the branching ratio between the two possible reaction outcomes. The merged-beam experimental technique used here allows access to a low-energy regime in which the atoms dynamically reorient into a favourable configuration for reaction, irrespective of their initial orientations.

AB - Improving the yield by modifying plant architecture was a key step during crop domestication. Here, we show that a 110-kb deletion on the short arm of chromosome 7 in Asian cultivated rice (Oryza sativa), which is closely linked to the previously identified PROSTRATE GROWTH 1 (PROG1) gene, harbors a tandem repeat of seven zinc-finger genes. Three of these genes regulate the plant architecture, suggesting that the deletion also promoted the critical transition from the prostrate growth and low yield of wild rice (O. rufipogon) to the erect growth and high yield of Asian cultivated rice. We refer to this locus as RICE PLANT ARCHITECTURE DOMESTICATION (RPAD). Further, a similar but independent 113 kb deletion is detected at the RPAD locus in African cultivated rice. These results indicate that the deletions, eliminating a tandem repeat of zinc-finger genes, may have been involved in the parallel domestication of plant architecture in Asian and African rice.

AB - Candida auris has recently emerged as a multi-drug resistant fungal pathogen that poses a serious global health threat, especially for patients in hospital intensive care units (ICUs). C. auris can colonize human skin and can spread by physical contact or contaminated surfaces and equipment. Here, we show that the mycoparasitic yeast Saccharomycopsis schoenii efficiently kills both sensitive and multi-drug resistant isolates of C. auris belonging to the same clade, as well as clinical isolates of other pathogenic species of the Candida genus suggesting novel approaches for biocontrol. PMID- 30297758 TI - Low breastmilk vitamin A concentration is prevalent in rural Ethiopia. AB - BACKGROUND: There is scant information on the breastmilk vitamin A (BMVA) concentration of lactating women in developing countries, partly due to lack of methods applicable in-field. OBJECTIVE: To assess BMVA concentrations of samples collected from lactating women of children aged 6-23 months, in Mecha district, Ethiopia. SUBJECTS/METHODS: Data on socio-demographic and anthropometric characteristics were collected from randomly selected lactating women (n = 104). Breast milk samples were collected and vitamin A concentrations were analyzed using HPLC and iCheck FLUORO then the two measurements were compared. RESULTS: The prevalence of underweight (BMI < 18.5 kg/m2) among lactating women was 17%. Seventy six percent of the BMVA values were <1.05 umol/l and 81% were <8 ug/g fat. The mean BMVA concentration accounted to 41% of the estimated average value for mothers in developing countries. The BMVA values from HPLC and iCheck were correlated (r = 0.59, p = < 0.001), but it was not strong. CONCLUSIONS: The result indicates the low vitamin A status of the lactating women and their children. It further indicates that intake assessments should not use average BMVA composition. The possibility of using iCheck for monitoring interventions designed to improve vitamin A status of lactating women with low BMVA requires further investigation.

AB - BACKGROUND/OBJECTIVES: Soaking oats overnight in milk renders them ready to eat the next morning, however, it is unknown whether oats prepared this way will retain its relatively low glycaemic and insulinaemic impact. Therefore, we compared the glycaemic, insulinaemic and subjective hunger responses elicited by oats soaked overnight in 110 g skim-milk (ONO) vs. cooked cream of rice cereal (CR), both with and without inclusions. SUBJECTS/METHODS: The project was performed at two research centers (Toronto, Winnipeg) as two separate studies each using a randomized, cross-over design with similar methods. The glycaemic and insulinaemic responses of overnight-fasted participants without diabetes (males:females: Toronto, 24:16; Winnipeg, 20:20) were measured for 3 h after consuming CR and ONO fed alone (Toronto) or with added sugar, nuts, and seeds (CRsns and ONOsns) (Winnipeg). Participants rated subjective hunger using visual analog scales. Data were analyzed by paired t-test. The primary endpoint was 0-2 h incremental area under the curve (iAUC) for glucose. RESULTS: Mean glucose iAUC was 33% less, after ONO than CR (mean difference was 39 (51-27) mmol * min/l, p < 0.0001) and 24% less, after ONOsns than CRsns (mean difference was 43 (65-21) mmol * min/l, p = 0.0003). Serum-insulin iAUC was 33% less, after ONO than CR (mean difference 57 (81-40) pmol * hl, p < 0.0001) and 32% less, after ONOsns than CRsns (966 (1360-572) pmol * h/l, p < 0.0001). In both Toronto and Winnipeg, subjective hunger ratings were similar across the two treatments. CONCLUSIONS: Oats prepared by soaking overnight in skimmed milk without and with inclusions retain their relatively low glycaemic and insulinaemic impact. PMID- 30297760 TI - Bioelectrical impedance analysis for body composition assessment: reflections on accuracy, clinical utility, and standardisation. AB - Bioelectrical impedance analysis is an extremely popular method for assessment of body composition. Despite its wide-spread use over the past thirty years, its accuracy and clinical value is still questioned. Most frequently, criticisms focus on its purported poor absolute accuracy and that different impedance analysers or prediction equations fail to measure body composition identically. This perspective review highlights that the magnitude of errors associated with impedance methods are not dissimilar to those observed for so-called gold standard methods. It is argued that the focus on statistically significant but small differences between methods can obscure operational equivalence and that such differences may be of minor clinical significance. Finally, the need for better standardization of protocols and the need for consensus on what is a minimal clinically important difference between methods is highlighted. PMID- 30297761 TI - Can legal restrictions of prenatal exposure to industrial trans-fatty acids reduce risk of childhood hematopoietic neoplasms? A population-based study. AB - BACKGROUND: Causes of most childhood hematopoietic neoplasms are unknown. Early age of occurrence suggests prenatal etiology. Positive associations have been reported between industrially produced trans-fatty acids (iTFAs) and risks of some cancers in adults. iTFAs are pro-inflammatory and adversely affect the beneficial effects of essential fatty acids, the latter is diminishing tumor growth. In 2004 Denmark legislated against the use of iTFA in foodstuffs. Using the entire population, we investigated if the changes in the legislation as a proxy to the reduced exposure to iTFA had affected the incidence of childhood hematopoietic neoplasms. METHODS: We used a Cox proportional hazard model to compare the hazard of childhood hematopoietic neoplasms among children born before and after the iTFA ban, as a proxy for fetal iTFA exposure. To take the potential secular trend in hematopoietic neoplasms into account, we modeled the variation in cancer risk across birth cohorts by a piecewise linear spline with a knot in 2004, which allowed a comparison of the hazard of childhood hematopoietic neoplasms between the time before and after the iTFA ban. RESULTS: Among children born in 1988-2008 in Denmark, 720 were diagnosed with hematopoietic neoplasms before the age of 7 years, corresponding to an overall incidence rate of 7.6 per 100 000 person years. The incidence rates increased by 2% per cohort in 1988-2004 (hazard ratio: 1.02 [1.01; 1.04]) and in 2004-2008 (hazard ratio: 1.02 [0.95; 1.11]). CONCLUSIONS: No apparent benefit of the iTFA legislation in reducing childhood hematopoietic neoplasms was observed on population basis. Individual level data are needed to investigate any possible associations between biomarkers of iTFA intake and risk of childhood hematopoietic neoplasms. PMID- 30297762 TI - Fitness versus adiposity in cardiovascular disease risk. AB - Obesity and low cardiorespiratory fitness are both established predictors of cardiovascular disease morbidity and mortality. Whether the protective effects of fitness outweigh the deleterious effects of obesity, however, remains a topic of debate. To extend knowledge of the relative influence of fitness and fatness on cardiovascular disease outcomes, however, attention must be paid to measurement quality. Eliminating inherent bias of self-report and including the highest quality assessments of cardiorespiratory fitness and fatness simultaneously are imperative for head-to-head comparisons. Studies must move beyond body mass index and total body fat percentage to differentiate the heterogenous effects of various adipose tissue depots on cardiovascular risk. Imaging techniques that measure visceral adiposity and other risk-laden ectopic adipose depots while also quantifying cardioprotective adipose depots such as lower body subcutaneous fat and even non-adipose tissues such as skeletal muscle may further illuminate the influence of body composition on cardiovascular health. This review underscores key studies within a large body of literature that provide the foundation for the fit-vs.-fat debate in the context of cardiovascular disease risk, and identifies important considerations for future research. PMID- 30297763 TI - Coffee consumption in hemodialysis patients: how many? AB - BACKGROUND AND AIMS: Coffee is one of the most widely consumed beverages worldwide. However, fluid intake restriction is an important and difficult challenge for hemodialysis (HD) patients. The aim of this study was to analyze the effect of coffee intake on hydration and nutritional parameters of HD patients. METHODS: This was an observational, cross-sectional, multicenter study where 373 HD patients from 8 dialysis centers in Portugal were enrolled. A face to-face questionnaire was applied and patient's clinical and body composition parameters were analyzed. The sample was divided into 3 groups depending on coffee intake: group 1-don't drink coffee, group 2-drink 1-2 coffees/day and group 3-drink 3 or more coffees/day. Laboratory and body composition parameters were registered in the month prior to the questionnaire application. Body composition was assessed with the Body Composition Monitor (BCM; Fresenius Medical Care Deutschland GmbH, Germany). RESULTS: Patient's mean age was 67.2 +/- 14.4 years and the mean HD vintage was 61.3 +/- 56.2 months. Patients who reported drinking 3 or more coffees daily were younger, presented higher levels of potassium, phosphorus, diastolic BP, albumin and interdialytic weight gain (IDWG) and lower dialysis adequacy (Kt/V). Regarding body composition, patients in the group 3 showed higher body cell mass index (BCMI) and lean tissue index (LTI). On the other hand, the group 1 were the oldest, had a higher Kt/V, a lower diastolic blood pressure (BP) and potassium levels, whereas G2 presented a lower LTI, BCMI and IDWG. CONCLUSIONS: Drinking 3 or more coffees daily increases the risk of a higher diastolic BP, potassium and IDWG in HD patients. PMID- 30297764 TI - Rapid and selective concentration of bacteria, viruses, and proteins using alternating current signal superimposition on two coplanar electrodes. AB - Dielectrophoresis (DEP) is usually effective close to the electrode surface. Several techniques have been developed to overcome its drawbacks and to enhance dielectrophoretic particle capture. Here we present a simple technique of superimposing alternating current DEP (high-frequency signals) and electroosmosis (EO; low-frequency signals) between two coplanar electrodes (gap: 25 MUm) using a lab-made voltage adder for rapid and selective concentration of bacteria, viruses, and proteins, where we controlled the voltages and frequencies of DEP and EO separately. This signal superimposition technique enhanced bacterial capture (Escherichia coli K-12 against 1-MUm-diameter polystyrene beads) more selectively (>99%) and rapidly (~30 s) at lower DEP (5 Vpp) and EO (1.2 Vpp) potentials than those used in the conventional DEP capture studies. Nanometer sized MS2 viruses and troponin I antibody proteins were also concentrated using the superimposed signals, and significantly more MS2 and cTnI-Ab were captured using the superimposed signals than the DEP (10 Vpp) or EO (2 Vpp) signals alone (p < 0.035) between the two coplanar electrodes and at a short exposure time (1 min). This technique has several advantages, such as simplicity and low cost of electrode fabrication, rapid and large collection without electrolysis. PMID- 30297765 TI - Vav1 mutations identified in human cancers give rise to different oncogenic phenotypes. AB - Vav1 is physiologically active as a GDP/GTP nucleotide exchange factor (GEF) in the hematopoietic system. Overexpression of Vav1 in multiple tumor types is known to enhance oncogenicity, yet whether or not Vav1 is a bona fide oncogene is still a matter of debate. Although mutations in Vav1 were recently identified in human cancers of various origins, the functional activities of these mutants are not known. We tested the transforming potential of three mutations identified in human lung adenocarcinoma: E59K, D517E, and L801P. Results from several assays indicative of transforming activities such as rate of proliferation, growth in agar, and generation of tumors in NOD/SCID mice clearly indicated that E59K and D517E are highly transforming but L801P at the SH3 domain is not. The acquired oncogenic activity of these mutants can be attributed to their enhanced activity as GEFs for Rho/Rac GTPases. Deciphering of the mechanisms leading to overactivity of the tested mutants revealed that the E59K mutation facilitates cleavage of a truncated protein that is uncontrollably active as a GEF, while D517E generates a highly stable overexpressed protein that is also more active as a GEF than wild-type Vav1. These findings support the classification of Vav1 as a bona fide oncogene in human cancer. PMID- 30297766 TI - Fractionalized excitations in the partially magnetized spin liquid candidate YbMgGaO4. AB - Quantum spin liquids (QSLs) are exotic states of matter characterized by emergent gauge structures and fractionalized elementary excitations. The recently discovered triangular lattice antiferromagnet YbMgGaO4 is a promising QSL candidate, and the nature of its ground state is still under debate. Here we use neutron scattering to study the spin excitations in YbMgGaO4 under various magnetic fields. Our data reveal a dispersive spin excitation continuum with clear upper and lower excitation edges under a weak magnetic field (H = 2.5 T). Moreover, a spectral crossing emerges at the Gamma point at the Zeeman-split energy. The corresponding redistribution of the spectral weight and its field dependent evolution are consistent with the theoretical prediction based on the inter-band and intra-band spinon particle-hole excitations associated with the Zeeman-split spinon bands, implying the presence of fractionalized excitations and spinon Fermi surfaces in the partially magnetized QSL state in YbMgGaO4. PMID- 30297768 TI - Gene coexpression network analysis combined with metabonomics reveals the resistance responses to powdery mildew in Tibetan hulless barley. AB - Powdery mildew is a fungal disease that represents a ubiquitous threat to crop plants. Transcriptomic and metabolomic analyses were used to identify molecular and physiological changes in Tibetan hulless barley in response to powdery mildew. There were 3418 genes and 405 metabolites differentially expressed between the complete resistance cultivar G7 and the sensitive cultivar Z13. Weighted gene coexpression network analysis was carried out, and the differentially expressed genes were enriched in five and four major network modules in G7 and Z13, respectively. Further analyses showed that phytohormones, photosynthesis, phenylpropanoid biosynthesis, and flavonoid biosynthesis pathways were altered during Qingke-Blumeria graminis (DC.) f.sp. hordei (Bgh) interaction. Comparative analyses showed a correspondence between gene expression and metabolite profiles, and the activated defenses resulted in changes of metabolites involved in plant defense response, such as phytohormones, lipids, flavone and flavonoids, phenolamides, and phenylpropanoids. This study enabled the identification of Bgh responsive genes and provided new insights into the dynamic physiological changes that occur in Qingke during response to powdery mildew. These findings greatly improve our understanding of the mechanisms of induced defense response in Qingke and will provide new clues for the development of resistant Tibetan hulless barley varieties. PMID- 30297767 TI - Dopamine-endocannabinoid interactions mediate spike-timing-dependent potentiation in the striatum. AB - Dopamine modulates striatal synaptic plasticity, a key substrate for action selection and procedural learning. Thus, characterizing the repertoire of activity-dependent plasticity in striatum and its dependence on dopamine is of crucial importance. We recently unraveled a striatal spike-timing-dependent long term potentiation (tLTP) mediated by endocannabinoids (eCBs) and induced with few spikes (~5-15). Whether this eCB-tLTP interacts with the dopaminergic system remains to be investigated. Here, we report that eCB-tLTP is impaired in a rodent model of Parkinson's disease and rescued by L-DOPA. Dopamine controls eCB-tLTP via dopamine type-2 receptors (D2R) located presynaptically in cortical terminals. Dopamine-endocannabinoid interactions via D2R are required for the emergence of tLTP in response to few coincident pre- and post-synaptic spikes and control eCB-plasticity by modulating the long-term potentiation (LTP)/depression (LTD) thresholds. While usually considered as a depressing synaptic function, our results show that eCBs in the presence of dopamine constitute a versatile system underlying bidirectional plasticity implicated in basal ganglia pathophysiology. PMID- 30297770 TI - Serially measured pre-diagnostic levels of serum cytokines and risk of brain cancer in active component military personnel. AB - BACKGROUND: There is growing evidence that history of allergic or autoimmune disease is associated with reduced risk of glioma, but few prospective studies have explored the biological basis. To assess associations with immune conditions and levels of 14 cytokines in serial prediagnostic serum samples, we conducted a study of glioma/brain cancer nested in a cohort of active component military personnel. METHODS: A total of 457 case-control sets were ascertained from the Department of Defense (DoD) Automated Central Tumour Registry, Defense Medical Surveillance System (DMSS) database, and DoD Serum Repository. These were individually matched on sex, race/ethnicity, birth year, number of serum samples (1, 2 or 3), and date(s) of sample collection. We obtained diagnoses of pre existing immune-related conditions from the DMSS database and measured cytokines using Meso Scale Discovery assays. Statistical analyses included conditional logistic regression. RESULTS: Overall association between glioma and prior immune related conditions was null. Higher levels of IL-15 and IL-16 were independently associated with lower glioma risks (Ptrend = 0.002 and Ptrend = 0.001); both associations were more pronounced in individuals with prior immune conditions (Pheterogeneity = 0.0009 and Pheterogeneity = 0.031). CONCLUSIONS: Associations with pre-diagnostic levels of IL-15 and IL-16 and their modification by diagnosis of immune-related conditions support the importance of immune alterations in glioma aetiology years before diagnosis. PMID- 30297769 TI - Pressure tuning of charge ordering in iron oxide. AB - A Verwey-type charge-ordering transition in magnetite at 120 K leads to the formation of linear units of three iron ions with one shared electron, called trimerons. The recently-discovered iron pentoxide (Fe4O5) comprising mixed-valent iron cations at octahedral chains, demonstrates another unusual charge-ordering transition at 150 K involving competing formation of iron trimerons and dimerons. Here, we experimentally show that applied pressure can tune the charge-ordering pattern in Fe4O5 and strongly affect the ordering temperature. We report two charge-ordered phases, the first of which may comprise both dimeron and trimeron units, whereas, the second exhibits an overall dimerization involving both the octahedral and trigonal-prismatic chains of iron in the crystal structure. We link the dramatic change in the charge-ordering pattern in the second phase to redistribution of electrons between the octahedral and prismatic iron chains, and propose that the average oxidation state of the iron cations can pre-determine a charge-ordering pattern.

PMID- 30297773 TI - Risk of diabetes after para-aortic radiation for testicular cancer. AB - BACKGROUND: While the risk of diabetes is increased following radiation exposure to the pancreas among childhood cancer survivors, its association among testicular cancer (TC) survivors has not been investigated. METHODS: Diabetes risk was studied in 2998 1-year TC survivors treated before 50 years of age with orchidectomy with/without radiotherapy between 1976 and 2007. Diabetes incidence was compared with general population rates. Treatment-specific risk of diabetes was assessed using a case-cohort design. RESULTS: With a median follow-up of 13.4 years, 161 TC survivors were diagnosed with diabetes. Diabetes risk was not increased compared to general population rates (standardised incidence ratios (SIR): 0.9; 95% confidence interval (95% CI): 0.7-1.1). Adjusted for age, para aortic radiotherapy was associated with a 1.66-fold (95% CI: 1.05-2.62) increased diabetes risk compared to no radiotherapy. The excess hazard increased with 0.31 with every 10 Gy increase in the prescribed radiation dose (95% CI: 0.11-0.51, P = 0.003, adjusted for age and BMI); restricted to irradiated patients the excess hazard increased with 0.33 (95% CI: -0.14 to 0.81, P = 0.169) with every 10 Gy increase in radiation dose. CONCLUSION: Compared to surgery only, para-aortic irradiation is associated with increased diabetes risk among TC survivors. PMID- 30297774 TI - Reconfigurable photoactuator through synergistic use of photochemical and photothermal effects. AB - A reconfigurable actuator is a stimuli-responsive structure that can be programmed to adapt different shapes under identical stimulus. Reconfigurable actuators that function without control circuitry and are fueled remotely are in great demand to devise adaptive soft robotic devices. Yet, obtaining fast and reliable reconfiguration remains a grand challenge. Here we report a facile fabrication pathway towards reconfigurability, through synergistic use of photochemical and photothermal responses in light-active liquid crystal polymer networks. We utilize azobenzene photoisomerization to locally control the cis isomer content and to program the actuator response, while subsequent photothermal stimulus actuates the structure, leading to shape morphing. We demonstrate six different shapes reconfigured from one single actuator under identical illumination conditions, and a light-fueled smart gripper that can be commanded to either grip and release or grip and hold an object after ceasing the illumination. We anticipate this work to enable all-optical control over actuator performance, paving way towards reprogrammable soft micro-robotics. PMID- 30297775 TI - Salt concentration and charging velocity determine ion charge storage mechanism in nanoporous supercapacitors. AB - A fundamental understanding of ion charge storage in nanoporous electrodes is essential to improve the performance of supercapacitors or devices for capacitive desalination. Here, we employ in situ X-ray transmission measurements on activated carbon supercapacitors to study ion concentration changes during electrochemical operation. Whereas counter-ion adsorption was found to dominate at small electrolyte salt concentrations and slow cycling speed, ion replacement prevails for high molar concentrations and/or fast cycling. Chronoamperometry measurements reveal two distinct time regimes of ion concentration changes. In the first regime the supercapacitor is charged, and counter- and co-ion concentration changes align with ion replacement and partially co-ion expulsion. In the second regime, the electrode charge remains constant, but the total ion concentration increases. We conclude that the initial fast charge neutralization in nanoporous supercapacitor electrodes leads to a non-equilibrium ion configuration. The subsequent, charge-neutral equilibration slowly increases the total ion concentration towards counter-ion adsorption.

PMID- 30297777 TI - Quasiparticle interference and nonsymmorphic effect on a floating band surface state of ZrSiSe. AB - Non-symmorphic crystals are generating great interest as they are commonly found in quantum materials, like iron-based superconductors, heavy-fermion compounds, and topological semimetals. A new type of surface state, a floating band, was recently discovered in the nodal-line semimetal ZrSiSe, but also exists in many non-symmorphic crystals. Little is known about its physical properties. Here, we employ scanning tunneling microscopy to measure the quasiparticle interference of the floating band state on ZrSiSe (001) surface and discover rotational symmetry breaking interference, healing effect and half-missing-type anomalous Umklapp scattering. Using simulation and theoretical analysis we establish that the phenomena are characteristic properties of a floating band surface state. Moreover, we uncover that the half-missing Umklapp process is derived from the glide mirror symmetry, thus identify a non-symmorphic effect on quasiparticle interferences. Our results may pave a way towards potential new applications of nanoelectronics. PMID- 30297779 TI - Misreading chaperone-substrate complexes from random noise. PMID- 30297780 TI - Reply to 'Misreading chaperone-substrate complexes from random noise'. PMID- 30297778 TI - A novel class of microRNA-recognition elements that function only within open reading frames. AB - MicroRNAs (miRNAs) are well known to target 3' untranslated regions (3' UTRs) in mRNAs, thereby silencing gene expression at the post-transcriptional level. Multiple reports have also indicated the ability of miRNAs to target protein coding sequences (CDS); however, miRNAs have been generally believed to function through similar mechanisms regardless of the locations of their sites of action. Here, we report a class of miRNA-recognition elements (MREs) that function exclusively in CDS regions. Through functional and mechanistic characterization of these 'unusual' MREs, we demonstrate that CDS-targeted miRNAs require extensive base-pairing at the 3' side rather than the 5' seed; cause gene silencing in an Argonaute-dependent but GW182-independent manner; and repress translation by inducing transient ribosome stalling instead of mRNA destabilization. These findings reveal distinct mechanisms and functional consequences of miRNAs that target CDS versus the 3' UTR and suggest that CDS targeted miRNAs may use a translational quality-control-related mechanism to regulate translation in mammalian cells. PMID- 30297782 TI - Multiple uncertainties require a change of conservation practices for saproxylic beetles in managed temperate forests. AB - In Europe, intensive forest management has severely compromised the habitat of forest insects, especially saproxylic beetles, due to the removal of deadwood and veteran trees. The loss of insect diversity may disrupt ecosystem functioning and affect the provision of important ecosystem goods and services in the future. Here we propose a novel approach for the implementation of conservation policies, by optimally allocating forest reserves and deadwood islands under multiple sources of uncertainty and minimizing economic risk. We use the saproxylic beetle Lucanus cervus as umbrella species, requiring that deadwood islands were spaced within its dispersal capacity. We show that current management and conservation practices are increasingly inefficient under changing environmental conditions and that the consideration of uncertainty requires a major expansion of conservation areas. Moreover, our results indicate that a strong diversification of management regimes, with a focus on selection forest systems, is required to reduce economic risk of forest management. We conclude that the integration of uncertainty into conservation planning may reduce the trade-off between production and conservation objectives in forest landscapes and is key to increase the efficiency of forest management in the future. PMID- 30297781 TI - Blood meal-induced inhibition of vector-borne disease by transgenic microbiota. AB - Vector-borne diseases are a substantial portion of the global disease burden; one of the deadliest of these is malaria. Vector control strategies have been hindered by mosquito and pathogen resistances, and population alteration approaches using transgenic mosquitos still have many hurdles to overcome before they can be implemented in the field. Here we report a paratransgenic control strategy in which the microbiota of Anopheles stephensi was engineered to produce an antiplasmodial effector causing the mosquito to become refractory to Plasmodium berghei. The midgut symbiont Asaia was used to conditionally express the antiplasmodial protein scorpine only when a blood meal was present. These blood meal inducible Asaia strains significantly inhibit pathogen infection, and display improved fitness compared to strains that constitutively express the antiplasmodial effector. This strategy may allow the antiplasmodial bacterial strains to survive and be transmitted through mosquito populations, creating an easily implemented and enduring vector control strategy. PMID- 30297783 TI - Personalized Integrated Network Modeling of the Cancer Proteome Atlas. AB - Personalized (patient-specific) approaches have recently emerged with a precision medicine paradigm that acknowledges the fact that molecular pathway structures and activity might be considerably different within and across tumors. The functional cancer genome and proteome provide rich sources of information to identify patient-specific variations in signaling pathways and activities within and across tumors; however, current analytic methods lack the ability to exploit the diverse and multi-layered architecture of these complex biological networks. We assessed pan-cancer pathway activities for >7700 patients across 32 tumor types from The Cancer Proteome Atlas by developing a personalized cancer-specific integrated network estimation (PRECISE) model. PRECISE is a general Bayesian framework for integrating existing interaction databases, data-driven de novo causal structures, and upstream molecular profiling data to estimate cancer specific integrated networks, infer patient-specific networks and elicit interpretable pathway-level signatures. PRECISE-based pathway signatures, can delineate pan-cancer commonalities and differences in proteomic network biology within and across tumors, demonstrates robust tumor stratification that is both biologically and clinically informative and superior prognostic power compared to existing approaches. Towards establishing the translational relevance of the functional proteome in research and clinical settings, we provide an online, publicly available, comprehensive database and visualization repository of our findings ( https://mjha.shinyapps.io/PRECISE/ ). PMID- 30297784 TI - Mammographic Density Distribution of Healthy Taiwanese Women and its Naturally Decreasing Trend with Age. AB - We analysed typical mammographic density (MD) distributions of healthy Taiwanese women to augment existing knowledge, clarify cancer risks, and focus public health efforts. From January 2011 to December 2015, 88,193 digital mammograms were obtained from 69,330 healthy Taiwanese women (average, 1.27 mammograms each). MD measurements included dense volume (DV) and volumetric density percentage (VPD) and were quantified by fully automated volumetric density estimation and Box-Cox normalization. Prediction of the declining MD trend was estimated using curve fitting and a rational model. Normalized DV and VPD Lowess curves demonstrated similar but non-identical distributions. In high-density grade participants, the VPD increased from 12.45% in the 35-39-year group to 13.29% in the 65-69-year group but only from 5.21% to 8.47% in low-density participants. Regarding the decreased cumulative VPD percentage, the mean MD declined from 12.79% to 19.31% in the 45-50-year group versus the 50-55-year group. The large MD decrease in the fifth decade in this present study was similar to previous observations of Western women. Obtaining an MD distribution model with age improves the understanding of breast density trends and age variations and provides a reference for future studies on associations between MD and cancer risk. PMID- 30297785 TI - Angle-dependent electron-electron correlation in the single ionization of H2 in strong laser fields. AB - The one-photon ionization and tunneling ionization of H2 exposed to strong XUV and infrared laser pulses are studied by numerically simulating the four dimensional time-dependent Schrodinger equation, which includes two-electron dynamics for arbitrary angle between the molecular axis and the laser polarization direction. In the one-photon single ionization of H2, one electron escapes fast and the other bound electron is not disturbed but remains in coherent superposition of two electronic states of [Formula: see text]. In another case, under the irradiation of strong infrared laser pulses, one electron tunnels through the laser-dressed Coulomb barrier, and the other bound electron has enough time to adapt to the potential of [Formula: see text] and thus is prone to transfer to the ground electronic state of [Formula: see text]. In the intermediate regime, between the one photon and tunneling regimes, this electron electron correlation depends strongly on the laser frequency, laser intensity and on the angle between laser polarization and the molecular axis. PMID- 30297787 TI - Transcriptomic analysis reveals a controlling mechanism for NLRP3 and IL-17A in dextran sulfate sodium (DSS)-induced colitis. AB - The incidence of inflammatory bowel disease (IBD) has markedly increased. Our research findings during the past showed that medicinal plant extracts and the derived phytochemical components from Wedelia chinensis (WC) can have strong anti colitis activities. Here, we further identified the key component phytochemicals from active fractions of different WC preparations (WCHA) that are responsible for the protective effect of WCHA in colitis mice. Of the 3 major compounds (wedelolactone, luteolin and apigenin) in this fraction, luteolin had the highest anti-inflammatory effect in vivo. Using a next-generation sequencing (NGS) (e.g., RNA-seq) system to analyze the transcriptome of colorectal cells/tissues in mice with dextran sulfate sodium (DSS)-induced colitis with/without phytochemicals treatment, luteolin was found to strongly suppress the DSS-activated IL-17 pathway in colon tissue. In addition, co-treatment with wedelolactone and luteolin had a synergistic effect on the expression level of some IL-17 pathway related genes. Interestingly, our NGS analyses also indicated that luteolin and wedelolactone can specifically suppress the expression of NLRP3 and NLRP1. Using a 3-dimensional cell co-culture system, we further demonstrated that luteolin could efficiently suppress NLRP3 expression via disruption of IL-17A signaling in inflamed colon tissue, which also indicates the pharmacological potential of luteolin and wedelolactone in treating IBD. PMID- 30297788 TI - Somatic alterations in circulating cell-free DNA of oesophageal carcinoma patients during primary staging are indicative for post-surgical tumour recurrence. AB - Oesophageal cancer (OC) has high mortality. This study aims at determining the feasibility of liquid biopsies for genomic profiling in early stage OC, comparing two different technologies for mutational analysis in circulating cell -free DNA (ccfDNA) and evaluating the clinical impact of these somatic alterations during primary staging. In 25 patients with locally advanced OC, endoscopic tumour biopsies and simultaneous blood samples were taken during primary staging. Genomic DNA from biopsies and ccfDNA were analysed for mutations using a 12 gene panel next-generation sequencing (NGS) assay as well as digital droplet PCR (ddPCR). Genetic data was correlated with patients' outcome. In 21 of the tested biopsies (84%) at least one somatic mutation was detected by NGS. Mutations detected by NGS were detectable by ddPCR with similar allele frequencies. In three out of the 21 patients with proven mutations, the same mutations were also detectable in ccfDNA using NGS (14%). In contrast, ddPCR detected mutations in ccfDNA of five additional patients (8/21, 38%). Post-surgical outcome analysis was performed for those patients who had received complete tumour resection (n = 16). Five of them suffered from an early relapse within the first year after surgery, including four with detectable somatic mutations in ccfDNA during primary staging. Taken together, we showed a higher sensitivity for ddPCR compared to NGS in detecting mutated ccfDNA in OC. Detection of somatically altered ccfDNA during primary staging seems to be indicative for post-surgical tumour recurrence. PMID- 30297786 TI - Electrophysiological evidence for abnormal glutamate-GABA association following psychosis onset. AB - Previous studies have shown glutamatergic dysfunction and gamma-aminobutyric acid (GABA)-ergic dysfunction in schizophrenia. Animal studies suggest that N-methyl-D aspartate receptor (NMDAR) dysfunction and GABA-ergic dysfunction interact with each other and lead to alterations in excitatory/inhibitory balance. The NMDAR and GABAergic-interneuron functions may be indexed by mismatch negativity (MMN) and auditory steady-state gamma-band response (ASSR), respectively. However, no previous studies have tested the hypothesis of an abnormal association between MMN and gamma-band ASSR in the same patients to identify the in vivo evidence of NMDAR-GABA association during the early stages of psychosis. Participants were individuals with recent-onset schizophrenia (ROSZ; N = 21), ultra-high risk (UHR; N = 27), and healthy controls (HCs; N = 24). The MMN amplitude was significantly impaired in ROSZ (p = 0.001, d = 1.20) and UHR (p = 0.003, d = 1.01) compared with HCs. The intertrial phase coherence (ITC) index of gamma-band ASSR was significantly reduced in ROSZ compared with HCs (p < 0.001, d = -1.27) and UHR (p = 0.032, d = -0.75). The event-related spectral perturbation (ERSP) index of gamma-band ASSR was significantly smaller in ROSZ compared with HCs (p < 0.001, d = -1.21). The MMN amplitude was significantly correlated with the ITC in ROSZ (r = -0.69, p < 0.001). These findings provide the first in vivo evidence that an abnormal association of the electrophysiological indices of NMDAR and GABA dysfunctions may be present in recent-onset schizophrenia. PMID- 30297789 TI - Typing tumors using pathways selected by somatic evolution. AB - Many recent efforts to analyze cancer genomes involve aggregation of mutations within reference maps of molecular pathways and protein networks. Here, we find these pathway studies are impeded by molecular interactions that are functionally irrelevant to cancer or the patient's tumor type, as these interactions diminish the contrast of driver pathways relative to individual frequently mutated genes. This problem can be addressed by creating stringent tumor-specific networks of biophysical protein interactions, identified by signatures of epistatic selection during tumor evolution. Using such an evolutionarily selected pathway (ESP) map, we analyze the major cancer genome atlases to derive a hierarchical classification of tumor subtypes linked to characteristic mutated pathways. These pathways are clinically prognostic and predictive, including the TP53-AXIN ARHGEF17 combination in liver and CYLC2-STK11-STK11IP in lung cancer, which we validate in independent cohorts. This ESP framework substantially improves the definition of cancer pathways and subtypes from tumor genome data. PMID- 30297790 TI - Regenerative potential of induced pluripotent stem cells derived from patients undergoing haemodialysis in kidney regeneration. AB - Kidney regeneration from pluripotent stem cells is receiving a lot of attention because limited treatments are currently available for chronic kidney disease (CKD). It has been shown that uremic state in CKD is toxic to somatic stem/progenitor cells, such as endothelial progenitor and mesenchymal stem cells, affecting their differentiation and angiogenic potential. Recent studies reported that specific abnormalities caused by the non-inherited disease are often retained in induced pluripotent stem cell (iPSC)-derived products obtained from patients. Thus, it is indispensable to first assess whether iPSCs derived from patients with CKD due to non-inherited disease (CKD-iPSCs) have the ability to generate kidneys. In this study, we generated iPSCs from patients undergoing haemodialysis due to diabetes nephropathy and glomerulonephritis (HD-iPSCs) as representatives of CKD-iPSCs or from healthy controls (HC-iPSCs). HD-iPSCs differentiated into nephron progenitor cells (NPCs) with similar efficiency to HC iPSCs. Additionally, HD-iPSC-derived NPCs expressed comparable levels of NPC markers and differentiated into vascularised glomeruli upon transplantation into mice, as HC-iPSC-derived NPCs. Our results indicate the potential of HD-iPSCs as a feasible cell source for kidney regeneration. This is the first study paving the way for CKD patient-stem cell-derived kidney regeneration, emphasising the potential of CKD-iPSCs. PMID- 30297791 TI - A reference document on Permissible Limits for solvents and buffers during in vitro antimalarial screening. AB - Antimalarial drug discovery expands on targeted and phenotype-based screening of potential inhibitory molecules to ascertain overall efficacy, phenotypic characteristics and toxicity, prior to exploring pharmacological optimizations. Candidate inhibitors may have varying chemical properties, thereby requiring specific reconstitution conditions to ensure solubility, stability or bioavailability. Hence, a variety of solvents, buffers, detergents and stabilizers become part of antimalarial efficacy assays, all of which, above certain threshold could interfere with parasite viability, invasion or red blood cell properties leading to misinterpretation of the results. Despite their routine use across malaria research laboratories, there is no documentation on non-toxic range for common constituents including DMSO, glycerol, ethanol and methanol. We herein constructed a compatibility reference guide for 14 such chemicals and estimated their Permissible Limit against P. falciparum asexual stages at which viability and replication of parasites are not compromised. We also demonstrate that at the estimated Permissible Limit, red blood cells remain healthy and viable for infection by merozoites. Taken together, this dataset provides a valuable reference tool for the acceptable concentration range for common chemicals during in vitro antimalarial tests. PMID- 30297792 TI - Cortical visual processing evokes short-latency reward-predicting cue responses in primate midbrain dopamine neurons. AB - After classical conditioning dopamine (DA) neurons exhibit short latency responses to reward-predicting visual cues. At least two possible projections could induce such DA responses; the cortical and subcortical visual pathways. Our recent study has shown that after a lesion of the striate cortex (V1), the superior colliculus (SC), a critical node of the subcortical visual pathway, can mediate short latency cue responses in the DA neurons of macaque monkeys. An obvious question then is does the cortical pathway have a similar capacity? Using the monkeys with a unilateral V1 lesion that took part in the preceding study, we recorded DA activity while they were performing the same classical conditioning task. However, in this study conditioned visual stimuli were presented to the intact visual field, and the effects of ipsilateral SC inactivation were examined. We found that after the SC was inactivated by injections of muscimol both conditioned behavioral responding and reward-predicting, short latency (~100 ms) cue-elicited DA neuronal responses were unaffected These results indicate that the intact cortical visual pathway can also mediate short latency cue elicited responses in DA neurons in the absence of a normally functioning subcortical visual system. PMID- 30297794 TI - Application of spin-crossover water soluble nanoparticles for use as MRI contrast agents. AB - Water soluble spin-crossover (SCO) iron(II) nanoparticles (NPs) were synthesized by the polyethylene glycol (PEG) coating of [Fe(Htrz)3-3*(NH2trz)3*](BF4)2 (x = 0, 0.1, 0.5 and 1). The NPs with x = 0.1 show gradual SCO behavior over 280-330 K in water. The relaxation times, T1 and T2, were determined and the thermally responsive T2 values making these NPs a candidate for use as a MRI contrast agent. PMID- 30297793 TI - Porphyromonas gingivalis bypasses epithelial barrier and modulates fibroblastic inflammatory response in an in vitro 3D spheroid model. AB - Porphyromonas gingivalis-induced inflammatory effects are mostly investigated in monolayer cultured cells. The aim of this study was to develop a 3D spheroid model of gingiva to take into account epithelio-fibroblastic interactions. Human gingival epithelial cells (ECs) and human oral fibroblasts (FBs) were cultured by hanging drop method to generate 3D microtissue (MT) whose structure was analyzed on histological sections and the cell-to-cell interactions were observed by scanning and transmission electron microscopy (SEM and TEM). MTs were infected by P. gingivalis and the impact on cell death (Apaf-1, caspase-3), inflammatory markers (TNF-alpha, IL-6, IL-8) and extracellular matrix components (Col-IV, E cadherin, integrin beta1) was evaluated by immunohistochemistry and RT-qPCR. Results were compared to those observed in situ in experimental periodontitis and in human gingival biopsies. MTs exhibited a well-defined spatial organization where ECs were organized in an external cellular multilayer, while, FBs constituted the core. The infection of MT demonstrated the ability of P. gingivalis to bypass the epithelial barrier in order to reach the fibroblastic core and induce disorganization of the spheroid structure. An increased cell death was observed in fibroblastic core. The development of such 3D model may be useful to define the role of EC-FB interactions on periodontal host-immune response and to assess the efficacy of new therapeutics. PMID- 30297795 TI - Applications of the new ESPEN definition of malnutrition and SARC-F in Chinese nursing home residents. AB - We aimed to compare the predictive capacity of malnutrition, sarcopenia, and malnutrition combined with sarcopenia for mortality in nursing home residents. We conducted a prospective study in four nursing homes in China. Nutrition status and sarcopenia were measured according to the new European Society of Clinical Nutrition and Metabolism (ESPEN) definition and SARC-F, respectively. The study population was divided into four groups: malnutrition with sarcopenia (MN+/SA+), malnutrition without sarcopenia (MN+/SA-), sarcopenia without malnutrition (MN /SA+), and normal nutrition without sarcopenia (MN-/SA-). The participants were followed up for 12 months. We included 329 participants. Thirty-eight participants (11.6%) had MN+/SA+, 38 participants (11.6%) had MN+/SA-, and 93 participants (28.3%) had MN-/SA+. The 1-year mortality was 18.3%, 21.5%, 18.4%, and 47.4% in the MN-/SA-, MN-/SA+, MN+/SA-, and MN+/SA+ groups, respectively. Compared to participants with MN-/SA-, participants with MN+/SA+ were at a significantly higher risk of mortality (adjusted hazard ratio [HR]: 3.19, 95% confidence interval [CI] 1.71-5.95); however, MN-/SA+ (adjusted HR: 1.24, 95% CI 0.69-2.22) and MN+/SA- (adjusted HR: 0.95, 95% CI 0.41-2.19) were not predictors of mortality. In conclusion, the coexistence of malnutrition and sarcopenia is a significant predictor of mortality in a study population of Chinese nursing home residents. PMID- 30297796 TI - The H3K9 methyltransferase SETDB1 maintains female identity in Drosophila germ cells. AB - The preservation of germ cell sexual identity is essential for gametogenesis. Here we show that H3K9me3-mediated gene silencing is integral to female fate maintenance in Drosophila germ cells. Germ cell specific loss of the H3K9me3 pathway members, the H3K9 methyltransferase SETDB1, WDE, and HP1a, leads to ectopic expression of genes, many of which are normally expressed in testis. SETDB1 controls the accumulation of H3K9me3 over a subset of these genes without spreading into neighboring loci. At phf7, a regulator of male germ cell sexual fate, the H3K9me3 peak falls over the silenced testis-specific transcription start site. Furthermore, H3K9me3 recruitment to phf7 and repression of testis specific transcription is dependent on the female sex determination gene Sxl. Thus, female identity is secured by an H3K9me3 epigenetic pathway in which Sxl is the upstream female-specific regulator, SETDB1 is the required chromatin writer, and phf7 is one of the critical SETDB1 target genes. PMID- 30297798 TI - Battery-operated integrated frequency comb generator. AB - Optical frequency combs are broadband sources that offer mutually coherent, equidistant spectral lines with unprecedented precision in frequency and timing for an array of applications1. Frequency combs generated in microresonators through the Kerr nonlinearity require a single-frequency pump laser and have the potential to provide highly compact, scalable and power-efficient devices2,3. Here we demonstrate a device-a laser-integrated Kerr frequency comb generator that fulfils this potential through use of extremely low-loss silicon nitride waveguides that form both the microresonator and an integrated laser cavity. Our device generates low-noise soliton-mode-locked combs with a repetition rate of 194 gigahertz at wavelengths near 1,550 nanometres using only 98 milliwatts of electrical pump power. The dual-cavity configuration that we use combines the laser and microresonator, demonstrating the flexibility afforded by close integration of these components, and together with the ultra low power consumption should enable production of highly portable and robust frequency and timing references, sensors and signal sources. This chip-based integration of microresonators and lasers should also provide tools with which to investigate the dynamics of comb and soliton generation. PMID- 30297797 TI - Structural insights into the electron/proton transfer pathways in the quinol:fumarate reductase from Desulfovibrio gigas. AB - The membrane-embedded quinol:fumarate reductase (QFR) in anaerobic bacteria catalyzes the reduction of fumarate to succinate by quinol in the anaerobic respiratory chain. The electron/proton-transfer pathways in QFRs remain controversial. Here we report the crystal structure of QFR from the anaerobic sulphate-reducing bacterium Desulfovibrio gigas (D. gigas) at 3.6 A resolution. The structure of the D. gigas QFR is a homo-dimer, each protomer comprising two hydrophilic subunits, A and B, and one transmembrane subunit C, together with six redox cofactors including two b-hemes. One menaquinone molecule is bound near heme bL in the hydrophobic subunit C. This location of the menaquinone-binding site differs from the menaquinol-binding cavity proposed previously for QFR from Wolinella succinogenes. The observed bound menaquinone might serve as an additional redox cofactor to mediate the proton-coupled electron transport across the membrane. Armed with these structural insights, we propose electron/proton transfer pathways in the quinol reduction of fumarate to succinate in the D. gigas QFR. PMID- 30297799 TI - A slow-cycling LGR5 tumour population mediates basal cell carcinoma relapse after therapy. AB - Basal cell carcinoma (BCC) is the most frequent cancer in humans and results from constitutive activation of the Hedgehog pathway1. Several Smoothened inhibitors are used to treat Hedgehog-mediated malignancies, including BCC and medulloblastoma2. Vismodegib, a Smoothened inhibitor, leads to BCC shrinkage in the majority of patients with BCC3, but the mechanism by which it mediates BCC regression is unknown. Here we used two genetically engineered mouse models of BCC4 to investigate the mechanisms by which inhibition of Smoothened mediates tumour regression. We found that vismodegib mediates BCC regression by inhibiting a hair follicle-like fate and promoting the differentiation of tumour cells. However, a small population of tumour cells persists and is responsible for tumour relapse following treatment discontinuation, mimicking the situation found in humans5. In both mouse and human BCC, this persisting, slow-cycling tumour population expresses LGR5 and is characterized by active Wnt signalling. Combining Lgr5 lineage ablation or inhibition of Wnt signalling with vismodegib treatment leads to eradication of BCC. Our results show that vismodegib induces tumour regression by promoting tumour differentiation, and demonstrates that the synergy between Wnt and Smoothened inhibitors is a clinically relevant strategy for overcoming tumour relapse in BCC. PMID- 30297800 TI - Exciton-polariton topological insulator. AB - Topological insulators-materials that are insulating in the bulk but allow electrons to flow on their surface-are striking examples of materials in which topological invariants are manifested in robustness against perturbations such as defects and disorder1. Their most prominent feature is the emergence of edge states at the boundary between areas with different topological properties. The observable physical effect is unidirectional robust transport of these edge states. Topological insulators were originally observed in the integer quantum Hall effect2 (in which conductance is quantized in a strong magnetic field) and subsequently suggested3-5 and observed6 to exist without a magnetic field, by virtue of other effects such as strong spin-orbit interaction. These were systems of correlated electrons. During the past decade, the concepts of topological physics have been introduced into other fields, including microwaves7,8, photonic systems9,10, cold atoms11,12, acoustics13,14 and even mechanics15. Recently, topological insulators were suggested to be possible in exciton-polariton systems16-18 organized as honeycomb (graphene-like) lattices, under the influence of a magnetic field. Exciton-polaritons are part-light, part-matter quasiparticles that emerge from strong coupling of quantum-well excitons and cavity photons19. Accordingly, the predicted topological effects differ from all those demonstrated thus far. Here we demonstrate experimentally an exciton polariton topological insulator. Our lattice of coupled semiconductor microcavities is excited non-resonantly by a laser, and an applied magnetic field leads to the unidirectional flow of a polariton wavepacket around the edge of the array. This chiral edge mode is populated by a polariton condensation mechanism. We use scanning imaging techniques in real space and Fourier space to measure photoluminescence and thus visualize the mode as it propagates. We demonstrate that the topological edge mode goes around defects, and that its propagation direction can be reversed by inverting the applied magnetic field. Our exciton polariton topological insulator paves the way for topological phenomena that involve light-matter interaction, amplification and the interaction of exciton polaritons as a nonlinear many-body system. PMID- 30297801 TI - A cell identity switch allows residual BCC to survive Hedgehog pathway inhibition. AB - Despite the efficacy of Hedgehog pathway inhibitors in the treatment of basal cell carcinoma (BCC)1, residual disease persists in some patients and may contribute to relapse when treatment is discontinued2. Here, to study the effect of the Smoothened inhibitor vismodegib on tumour clearance, we have used a Ptch1 Trp53 mouse model of BCC3 and found that mice treated with vismodegib harbour quiescent residual tumours that regrow upon cessation of treatment. Profiling experiments revealed that residual BCCs initiate a transcriptional program that closely resembles that of stem cells of the interfollicular epidermis and isthmus, whereas untreated BCCs are more similar to the hair follicle bulge. This cell identity switch was enabled by a mostly permissive chromatin state accompanied by rapid Wnt pathway activation and reprogramming of super enhancers to drive activation of key transcription factors involved in cellular identity. Accordingly, treatment of BCC with both vismodegib and a Wnt pathway inhibitor reduced the residual tumour burden and enhanced differentiation. Our study identifies a resistance mechanism in which tumour cells evade treatment by adopting an alternative identity that does not rely on the original oncogenic driver for survival. PMID- 30297802 TI - Metallo-Curcumin-Conjugated DNA Complexes Induces Preferential Prostate Cancer Cells Cytotoxicity and Pause Growth of Bacterial Cells. AB - DNA nanotechnology can be used to create intricate DNA structures due to the ability to direct the molecular assembly of nanostructures through a bottom-up approach. Here, we propose nanocarriers composed of both synthetic and natural DNA for drug delivery. The topological, optical characteristics, and interaction studies of Cu2+/Ni2+/Zn2+-curcumin-conjugated DNA complexes were studied using atomic force microscopy (AFM), UV-vis spectroscopy, Fourier transform infrared and mass spectroscopy. The maximum release of metallo-curcumin conjugates from the DNA complexes, triggered by switching the pH, was found in an acidic medium. The bacterial growth curves of E. coli and B. subtilis displayed a prolonged lag phase when tested with the metallo-curcumin-conjugated DNA complexes. We also tested the in vitro cytotoxicity of the metallo-curcumin-conjugated DNA complexes to prostate cancer cells using an MTS assay, which indicated potent growth inhibition of the cells. Finally, we studied the cellular uptake of the complexes, revealing that DNA complexes with Cu2+/Ni2+-curcumin exhibited brighter fluorescence than those with Zn2+-curcumin. PMID- 30297803 TI - Dielectric Response of Quantum Critical Ferroelectric as a Function of Pressure. AB - In this work we report for the first time measurements of the dielectric loss of single-crystal SrTiO3 under the application of hydrostatic pressure up to 20 kbar and temperatures down to 200 mK which allow us to comment on the evolution of new fundamental material properties and their relationship with the recently discovered quantum critical phenomena in this material. The well known 18 K peak or shoulder was no longer observed after pressure was applied, even after subsequently removing it, suggesting it is associated with the twin walls formed at the 110 K cubic-tetragonal transition. The family of familiar peaks were all seen to increase in temperature linearly with pressure and the height of the 9.4 K peak was drastically suppressed by even the smallest pressures. This peak is discussed in the context of a postulated ferroelectric quantum critical point in SrTiO3 and the behaviour of its size linked to the position of this point on the recently established phase diagram. PMID- 30297804 TI - MNK1 inhibitor CGP57380 overcomes mTOR inhibitor-induced activation of eIF4E: the mechanism of synergic killing of human T-ALL cells. AB - Although the treatment of adult T-cell acute lymphoblastic leukemia (T-ALL) has been significantly improved, the heterogeneous genetic landscape of the disease often causes relapse. Aberrant activation of mammalian target of rapamycin (mTOR) pathway in T-ALL is responsible for treatment failure and relapse, suggesting that mTOR inhibition may represents a new therapeutic strategy. In this study, we investigated whether the mTOR complex 1 (mTORC1) inhibitor everolimus could be used as a therapeutic agent against human T-ALL. We showed that rapamycin and its analog RAD001 (everolimus) exerted only mild inhibition on the viability of Jurkat, CEM and Molt-4 cell lines (for everolimus the maximum inhibition was <40% at 100 nM), but greatly enhanced the phosphorylation of eIF4E, a downstream substrate of MAPK-interacting kinase (MNK) that was involved in promoting cell survival. Furthermore, we demonstrated in Jurkat cells that mTOR inhibitor induced eIF4E phosphorylation was independent of insulin-like growth factor 1/insulin-like growth factor-1 receptor axis, but was secondary to mTOR inhibition. Then we examined the antileukemia effects of CGP57380, a MNK1 inhibitor, and we found that CGP57380 (4-16 MUM) dose-dependently suppressed the expression of both phosphor-MNK1 and phosphor-eIF4E, thereby inhibiting downstream targets such as c-Myc and survivin in T-ALL cells. Importantly, CGP57380 produced a synergistic growth inhibitory effect with everolimus in T-ALL cells, and treatment with this targeted therapy overcame everolimus-induced eIF4E phosphorylation. In conclusion, our results suggest that dual-targeting of mTOR and MNK1/eIF4E signaling pathways may represent a novel therapeutic strategy for the treatment of human T-ALL. PMID- 30297805 TI - Subtomogram averaging of COPII assemblies reveals how coat organization dictates membrane shape. AB - Eukaryotic cells employ membrane-bound carriers to transport cargo between compartments in a process essential to cell functionality. Carriers are generated by coat complexes that couple cargo capture to membrane deformation. The COPII coat mediates export from the endoplasmic reticulum by assembling in inner and outer layers, yielding carriers of variable shape and size that allow secretion of thousands of diverse cargo. Despite detailed understanding of COPII subunits, the molecular mechanisms of coat assembly and membrane deformation are unclear. Here we present a 4.9 A cryo-tomography subtomogram averaging structure of in vitro-reconstituted membrane-bound inner coat. We show that the outer coat (Sec13 Sec31) bridges inner coat subunits (Sar1-Sec23-Sec24), promoting their assembly into a tight lattice. We directly visualize the membrane-embedded Sar1 amphipathic helix, revealing that lattice formation induces parallel helix insertions, yielding tubular curvature. We propose that regulators like the procollagen receptor TANGO1 modulate this mechanism to determine vesicle shape and size. PMID- 30297806 TI - LINCS L1000 dataset-based repositioning of CGP-60474 as a highly potent anti endotoxemic agent. AB - Sepsis is one of the most common clinical syndromes that causes death and disability. Although many studies have developed drugs for sepsis treatment, none have decreased the mortality rate. The aim of this study was to identify a novel treatment option for sepsis using the library of integrated network-based cellular signatures (LINCS) L1000 perturbation dataset based on an in vitro and in vivo sepsis model. Sepsis-related microarray studies of early-stage inflammatory processes in patients and innate immune cells were collected from the Gene Expression Omnibus (GEO) data repository and used for candidate drug selection based on the LINCS L1000 perturbation dataset. The anti-inflammatory effects of the selected candidate drugs were analyzed using activated macrophage cell lines. CGP-60474, an inhibitor of cyclin-dependent kinase, was the most potent drug. It alleviated tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) in activated macrophages by downregulating the NF-kappaB activity, and it reduced the mortality rate in LPS induced endotoxemia mice. This study shows that CGP-60474 could be a potential therapeutic candidate to attenuate the endotoxemic process. Additionally, the virtual screening strategy using the LINCS L1000 perturbation dataset could be a cost and time effective tool in the early stages of drug development. PMID- 30297807 TI - Integration of gene expression and brain-wide connectivity reveals the multiscale organization of mouse hippocampal networks. AB - Understanding the organization of the hippocampus is fundamental to understanding brain function related to learning, memory, emotions, and diseases such as Alzheimer's disease. Physiological studies in humans and rodents have suggested that there is both structural and functional heterogeneity along the longitudinal axis of the hippocampus. However, the recent discovery of discrete gene expression domains in the mouse hippocampus has provided the opportunity to re evaluate hippocampal connectivity. To integrate mouse hippocampal gene expression and connectivity, we mapped the distribution of distinct gene expression patterns in mouse hippocampus and subiculum to create the Hippocampus Gene Expression Atlas (HGEA). Notably, previously unknown subiculum gene expression patterns revealed a hidden laminar organization. Guided by the HGEA, we constructed the most detailed hippocampal connectome available using Mouse Connectome Project ( http://www.mouseconnectome.org ) tract tracing data. Our results define the hippocampus' multiscale network organization and elucidate each subnetwork's unique brain-wide connectivity patterns. PMID- 30297809 TI - Portable low-cost instrumentation for monitoring Rayleigh scattering from chemical sensors based on metallic nanoparticles. AB - Using a Hg(II) sensor based on the aggregation of gold nanoparticles as a model system, we evaluated the performance of two portable low-cost devices that monitor the wavelength-ratiometric resonance Rayleigh scattering signal of the chemical sensor upon white-LED illumination. The first device uses two optical filter-photodiode combinations to detect scattered light while the second employs a novel ultra-compact (grating-free) spectral sensor. Results show that the response of the Hg(II) sensor monitored with these devices is comparable to that measured using a high-end benchtop scanning spectrofluorometer. The great potential of this new LED-spectral sensor was demonstrated with the quantification of Hg(II) in tap and spring water. Due to the promising results obtained, many reported chemical sensors based on Rayleigh scattering from metallic nanoparticles could take advantage of this compact portable instrumentation for cost-effective field-deployable applications. PMID- 30297808 TI - Epigenomic map of human liver reveals principles of zonated morphogenic and metabolic control. AB - A deeper epigenomic understanding of spatial organization of cells in human tissues is an important challenge. Here we report the first combined positional analysis of transcriptomes and methylomes across three micro-dissected zones (pericentral, intermediate and periportal) of human liver. We identify pronounced anti-correlated transcriptional and methylation gradients including a core of 271 genes controlling zonated metabolic and morphogen networks and observe a prominent porto-central gradient of DNA methylation at binding sites of 46 transcription factors. The gradient includes an epigenetic and transcriptional Wnt signature supporting the concept of a pericentral hepatocyte regeneration pathway under steady-state conditions. While donors with non-alcoholic fatty liver disease show consistent gene expression differences corresponding to the severity of the disease across all zones, the relative zonated gene expression and DNA methylation patterns remain unchanged. Overall our data provide a wealth of new positional insights into zonal networks controlled by epigenetic and transcriptional gradients in human liver. PMID- 30297811 TI - Transparency revealed. PMID- 30297812 TI - Polarity governs atomic interaction through two-dimensional materials. AB - The transparency of two-dimensional (2D) materials to intermolecular interactions of crystalline materials has been an unresolved topic. Here we report that remote atomic interaction through 2D materials is governed by the binding nature, that is, the polarity of atomic bonds, both in the underlying substrates and in 2D material interlayers. Although the potential field from covalent-bonded materials is screened by a monolayer of graphene, that from ionic-bonded materials is strong enough to penetrate through a few layers of graphene. Such field penetration is substantially attenuated by 2D hexagonal boron nitride, which itself has polarization in its atomic bonds. Based on the control of transparency, modulated by the nature of materials as well as interlayer thickness, various types of single-crystalline materials across the periodic table can be epitaxially grown on 2D material-coated substrates. The epitaxial films can subsequently be released as free-standing membranes, which provides unique opportunities for the heterointegration of arbitrary single-crystalline thin films in functional applications. PMID- 30297813 TI - Programmed assembly of synthetic protocells into thermoresponsive prototissues. AB - Although several new types of synthetic cell-like entities are now available, their structural integration into spatially interlinked prototissues that communicate and display coordinated functions remains a considerable challenge. Here we describe the programmed assembly of synthetic prototissue constructs based on the bio-orthogonal adhesion of a spatially confined binary community of protein-polymer protocells, termed proteinosomes. The thermoresponsive properties of the interlinked proteinosomes are used collectively to generate prototissue spheroids capable of reversible contractions that can be enzymatically modulated and exploited for mechanochemical transduction. Overall, our methodology opens up a route to the fabrication of artificial tissue-like materials capable of collective behaviours, and addresses important emerging challenges in bottom-up synthetic biology and bioinspired engineering.

One of the impediments in nanoparticle based tumor targeting is the inability to limit the trafficking of nanoparticles to liver and other organs leading to smaller accumulated amounts in tumor tissues, particularly via passive targeting. Here we overcome both these challenges by designing nanoparticles that combine the specificity of antibodies with favorable particle biodistribution profiles, while not exceeding the threshold for renal filtration as a combined vehicle. To that end, ultrasmall silica nanoparticles are functionalized with anti-human epidermal growth factor receptor 2 (HER2) single-chain variable fragments to exhibit high tumor-targeting efficiency and efficient renal clearance. This ultrasmall targeted nanotheranostics/nanotherapeutic platform has broad utility, both for imaging a variety of tumor tissues by suitably adopting the targeting fragment and as a potentially useful drug delivery vehicle. PMID- 30297814 TI - Interparticle hydrogen bonding can elicit shear jamming in dense suspensions. AB - Dense suspensions of hard particles in a liquid can exhibit strikingly counter intuitive behaviour, such as discontinuous shear thickening (DST)1-7 and reversible shear jamming (SJ) into a state where flow is arrested and the suspension is solid-like8-12. A stress-activated crossover from hydrodynamic interactions to frictional particle contacts is key for these behaviours2 4,6,7,9,13. However, in experiments, many suspensions show only DST, not SJ. Here we show that particle surface chemistry plays a central role in creating conditions that make SJ readily observable. We find the system's ability to form interparticle hydrogen bonds when sheared into contact elicits SJ. We demonstrate this with charge-stabilized polymer microspheres and non-spherical cornstarch particles, controlling hydrogen bond formation with solvents. The propensity for SJ is quantified by tensile tests12 and linked to an enhanced friction by atomic force microscopy. Our results extend the fundamental understanding of the SJ mechanism and open avenues for designing strongly non-Newtonian fluids. PMID- 30297815 TI - Gaseous flow through heterogeneous, partially connected networks of pipes. AB - Simulations of flow of an ideal gas through heterogeneous simple cubic pipe networks with different pipe radius distributions and variable bond coordination numbers were performed. Networks with monomodal and bimodal radius distributions were constructed. A very wide range of Knudsen numbers was achieved. Flow simulations of purely viscous gases and incompressible liquids were also carried out for comparison. The permeability to gas in the purely viscous regime was larger than the permeability to an incompressible liquid. Based on a variety of computational tests, this result was likely not a numerical artifact. The simulated macroscopic flow behavior differed from the underlying single pipe model, depending on the radius distribution, network connectivity and magnitude of the externally applied pressure gradient, and was compatible with the Klinkenberg analysis only when the maximum Knudsen number used in each simulation was lower than 1. In this condition, the Klinkenberg coefficient was nearly proportional to the inverse of the network hydraulic radius while the effect of the radius distribution was weak and that of the network connectivity essentially negligible. The bimodal simulations displayed a typical percolation behavior, with the Klinkenberg coefficient remaining constant as long as the large pipe population was connected. PMID- 30297817 TI - A plug-and-play approach for malaria vaccination. PMID- 30297818 TI - A malaria vaccine adjuvant based on recombinant antigen binding to liposomes. AB - Pfs25 is a malaria transmission-blocking vaccine antigen candidate, but its apparently limited immunogenicity in humans has hindered clinical development. Here, we show that recombinant, polyhistidine-tagged (his-tagged) Pfs25 can be mixed at the time of immunization with pre-formed liposomes containing cobalt porphyrin-phospholipid, resulting in spontaneous nanoliposome antigen particleization (SNAP). Antigens are stably presented in uniformly orientated display via his-tag insertion in the cobalt porphyrin-phospholipid bilayer, without covalent modification or disruption of antigen conformation. SNAP immunization of mice and rabbits is well tolerated with minimal local reactogenicity, and results in orders-of-magnitude higher functional antibody generation compared with other 'mix-and-inject' adjuvants. Serum-stable antigen binding during transit to draining lymph nodes leads to enhanced antigen uptake by phagocytic antigen-presenting cells, with subsequent generation of long-lived, antigen-specific plasma cells. Seamless multiplexing with four additional his tagged Plasmodium falciparum polypeptides induces strong and balanced antibody production, illustrating the simplicity of developing multistage particulate vaccines with SNAP immunization. PMID- 30297816 TI - Ghrelin-O-Acyltransferase (GOAT) Enzyme as a Novel Potential Biomarker in Gastroenteropancreatic Neuroendocrine Tumors. AB - OBJECTIVES: The association between the presence and alterations of the components of the ghrelin system and the development and progression of neuroendocrine tumors (NETs) is still controversial and remains unclear. METHODS: Here, we systematically evaluated the expression levels (by quantitative-PCR) of key ghrelin system components of in gastroenteropancreatic (GEP)-NETs, as compared to non-tumor adjacent (NTA; n = 42) and normal tissues (NT; n = 14). Then, we analyzed their putative associations with clinical-histological characteristics. RESULTS: The results indicate that ghrelin and its receptor GHSR1a are present in a high proportion of normal tissues, while the enzyme ghrelin-O-acyltransferase (GOAT) and the splicing variants In1-ghrelin and GHSR1b were present in a lower proportion of normal tissues. In contrast, all ghrelin system components were present in a high proportion of tumor and NTA tissues. GOAT was significantly overexpressed (by quantitative-PCR (qPCR)) in tumor samples compared to NTA, while a trend was found for ghrelin, In1-ghrelin and GHSR1a. In addition, expression of these components displayed significant correlations with key clinical parameters. The marked overexpression of GOAT in tumor samples compared to NTA regions was confirmed by IHC, revealing that this enzyme is particularly overexpressed in gastrointestinal NETs, where it is directly correlated with tumor diameter. CONCLUSIONS: These results provide novel information on the presence and potential pathophysiological implications of the ghrelin system components in GEP-NETs, wherein GOAT might represent a novel diagnostic biomarker. PMID- 30297819 TI - Intracellular speciation of gold nanorods alters the conformational dynamics of genomic DNA. AB - Gold nanorods are one of the most widely explored inorganic materials in nanomedicine for diagnostics, therapeutics and sensing1. It has been shown that gold nanorods are not cytotoxic and localize within cytoplasmic vesicles following endocytosis, with no nuclear localization2,3, but other studies have reported alterations in gene expression profiles in cells following exposure to gold nanorods, via unknown mechanisms4. In this work we describe a pathway that can contribute to this phenomenon. By mapping the intracellular chemical speciation process of gold nanorods, we show that the commonly used Au-thiol conjugation, which is important for maintaining the noble (inert) properties of gold nanostructures, is altered following endocytosis, resulting in the formation of Au(I)-thiolates that localize in the nucleus5. Furthermore, we show that nuclear localization of the gold species perturbs the dynamic microenvironment within the nucleus and triggers alteration of gene expression in human cells. We demonstrate this using quantitative visualization of ubiquitous DNA G-quadruplex structures, which are sensitive to ionic imbalances, as an indicator of the formation of structural alterations in genomic DNA. PMID- 30297820 TI - Ice rule fragility via topological charge transfer in artificial colloidal ice. AB - Artificial particle ices are model systems of constrained, interacting particles. They have been introduced theoretically to study ice-manifolds emergent from frustration, along with domain wall and grain boundary dynamics, doping, pinning depinning, controlled transport of topological defects, avalanches, and memory effects. Recently such particle-based ices have been experimentally realized with vortices in nano-patterned superconductors or gravitationally trapped colloids. Here we demonstrate that, although these ices are generally considered equivalent to magnetic spin ices, they can access a novel spectrum of phenomenologies that are inaccessible to the latter. With experiments, theory and simulations we demonstrate that in mixed coordination geometries, entropy-driven negative monopoles spontaneously appear at a density determined by the vertex-mixture ratio. Unlike its spin-based analogue, the colloidal system displays a "fragile ice" manifold, where local energetics oppose the ice rule, which is instead enforced through conservation of the global topological charge. The fragile colloidal ice, stabilized by topology, can be spontaneously broken by topological charge transfer. PMID- 30297821 TI - High-efficiency optogenetic silencing with soma-targeted anion-conducting channelrhodopsins. AB - Optogenetic silencing allows time-resolved functional interrogation of defined neuronal populations. However, the limitations of inhibitory optogenetic tools impose stringent constraints on experimental paradigms. The high light power requirement of light-driven ion pumps and their effects on intracellular ion homeostasis pose unique challenges, particularly in experiments that demand inhibition of a widespread neuronal population in vivo. Guillardia theta anion conducting channelrhodopsins (GtACRs) are promising in this regard, due to their high single-channel conductance and favorable photon-ion stoichiometry. However, GtACRs show poor membrane targeting in mammalian cells, and the activity of such channels can cause transient excitation in the axon due to an excitatory chloride reversal potential in this compartment. Here, we address these problems by enhancing membrane targeting and subcellular compartmentalization of GtACRs. The resulting soma-targeted GtACRs show improved photocurrents, reduced axonal excitation and high light sensitivity, allowing highly efficient inhibition of neuronal activity in the mammalian brain. PMID- 30297822 TI - Predicting El Nino Beyond 1-year Lead: Effect of the Western Hemisphere Warm Pool. AB - Due to the profound impact of El Nino-Southern Oscillation (ENSO) on global climate and weather, extensive research has been devoted to its prediction. However, prediction accuracy based on observation is still insufficient and largely limited to less than one year of lead time. In this study, we demonstrate the possibility that anomalous sea surface temperature (SST) warming (cooling) in the Western Hemisphere Warm Pool (WHWP, a.k.a. Atlantic Warm Pool) near the Intra Americas Sea (IAS), which is the second largest warm pool on the planet, contributes to the initiation of La Nina (El Nino) with a 17-month lag time. SST anomalies in WHWP in late boreal summer contribute significantly to the emergence of the Pacific meridional mode (PMM) via interaction between the ocean and atmosphere over the subtropical North Pacific during the subsequent winter and spring. Near-equatorial surface wind anomalies associated with the PMM can further trigger ENSO through the dynamics of the equatorial oceanic waves. Thus, this observational analysis presents a clear step-by-step explanation about the influence of WHWP on ENSO development with a 17-month lead time. PMID- 30297825 TI - Evolutionary changes in growth, regrowth and carbohydrate storage in an invasive plant. AB - We hypothesized that due to the absence of specialist herbivores in introduced ranges, invasive plants have evolved decreased allocation to carbohydrate storage for regrowth ability and as a consequence allocate more to growth. In this study, we compared plant growth, carbohydrate storage and regrowth ability of invasive and native Jacobaea vulgaris in response to complete shoot defoliation. We used invasive J. vulgaris genotypes from three geographically and climactically distinct regions and compared these with native genotypes from Europe. We found that invasive genotypes initially grew larger while native genotypes regrew larger after defoliation. Before defoliation, the carbohydrate storage in roots of invasive genotypes was 38% lower than native genotypes. Biomass after regrowth increased with root carbohydrate storage while it decreased with structural root mass, showing that it is crucial to study root storage and structural components separately in order to investigate plant regrowth. All studied traits of invasive populations from the three geographically and climatologically distinct regions changed in the same expected direction suggesting that the shifts in herbivore guild were causal to the observed change in growth and regrowth ability rather than environmental factors. PMID- 30297823 TI - Rifamycin congeners kanglemycins are active against rifampicin-resistant bacteria via a distinct mechanism. AB - Rifamycin antibiotics (Rifs) target bacterial RNA polymerases (RNAPs) and are widely used to treat infections including tuberculosis. The utility of these compounds is threatened by the increasing incidence of resistance (RifR). As resistance mechanisms found in clinical settings may also occur in natural environments, here we postulated that bacteria could have evolved to produce rifamycin congeners active against clinically relevant resistance phenotypes. We survey soil metagenomes and identify a tailoring enzyme-rich family of gene clusters encoding biosynthesis of rifamycin congeners (kanglemycins, Kangs) with potent in vivo and in vitro activity against the most common clinically relevant RifR mutations. Our structural and mechanistic analyses reveal the basis for Kang inhibition of RifR RNAP. Unlike Rifs, Kangs function through a mechanism that includes interfering with 5'-initiating substrate binding. Our results suggest that examining soil microbiomes for new analogues of clinically used antibiotics may uncover metabolites capable of circumventing clinically important resistance mechanisms. PMID- 30297824 TI - The experience of vivid autobiographical reminiscence is supported by subjective content representations in the precuneus. AB - The human posteromedial cortex, which includes core regions of the default mode network (DMN), is thought to play an important role in episodic memory. However, the nature and functional role of representations in these brain regions remain unspecified. Nine participants (all female) wore smartphone devices to record episodes from their daily lives for multiple weeks, each night indicating the personally-salient attributes of each episode. Participants then relived their experiences in an fMRI scanner cued by images from their own lives. Representational Similarity Analysis revealed a broad network, including parts of the DMN, that represented personal semantics during autobiographical reminiscence. Within this network, activity in the right precuneus reflected more detailed representations of subjective contents during vivid relative to non vivid, recollection. Our results suggest a more specific mechanism underlying the phenomenology of vivid autobiographical reminiscence, supported by rich subjective content representations in the precuneus, a hub of the DMN previously implicated in metacognitive evaluations during memory retrieval. PMID- 30297826 TI - Microscale heat transfer and thermal extinction of a wire-grid polarizer. AB - We explore heat transfer and thermal characteristics of a wire-grid polarizer (WGP) on a microscale by investigating the effect of various geometrical parameters such as wire-grid period, height, and a fill factor. The thermal properties arise from heat transfer by light absorption and conduction in wire grids. Fill factor was found to be the most dominant geometrical parameter. For TM polarized light, a higher fill factor with thicker wire-grids increased the temperature. The local temperature was found to rise up to Tmax = 354.5 K. TE polarization tended to produce lower temperature. Thermal extinction due to polarimetric extinction by a WGP was also evaluated and highest extinction was observed to be 4.78 dB, which represents a temperature difference DeltaT = 54.3 degrees C. We expect the results to be useful for WGPs in polarization-sensitive thermal switching applications. PMID- 30297828 TI - TGF-beta2 downregulates osteogenesis under inflammatory conditions in dental follicle stem cells. AB - Bone formation is important for the reconstruction of bone-related structures in areas that have been damaged by inflammation. Inflammatory conditions such as those that occur in patients with rheumatoid arthritis, cystic fibrosis, and periodontitis have been shown to inhibit osteoblastic differentiation. This study focussed on dental follicle stem cells (DFSCs), which are found in developing tooth germ and participate in the reconstruction of alveolar bone and periodontal tissue in periodontal disease. After bacterial infection of inflamed dental tissue, the destruction of bone was observed. Currently, little is known about the relationship between the inflammatory environment and bone formation. Osteogenic differentiation of inflamed DFSCs resulted in decreased alkaline phosphatase (ALP) activity and alizarin red S staining compared to normal DFSCs. Additionally, in vivo transplantation of inflamed and normal DFSCs demonstrated severe impairment of osteogenesis by inflamed DFSCs. Protein profile analysis via liquid chromatography coupled with tandem mass spectrometry was performed to analyse the differences in protein expression in inflamed and normal tissue. Comparison of inflamed and normal DFSCs showed significant changes in the level of expression of transforming growth factor (TGF)-beta2. Porphyromonas gingivalis (P.g.)-derived lipopolysaccharide (LPS) was used to create in vitro inflammatory conditions similar to periodontitis. The osteogenic differentiation of LPS treated DFSCs was suppressed, and the cells displayed low levels of TGF-beta1 and high levels of TGF-beta2. DFSCs treated with TGF-beta2 inhibitors showed significant increases in alizarin red S staining and ALP activity. TGF-beta1 expression was also increased after inhibition of TGF-beta2. By examining inflamed DFSCs and LPS-triggered DFSCs, these studies showed both clinically and experimentally that the increase in TGF-beta2 levels that occurs under inflammatory conditions inhibits bone formation. PMID- 30297827 TI - Melatonin inhibits attention-deficit/hyperactivity disorder caused by atopic dermatitis-induced psychological stress in an NC/Nga atopic-like mouse model. AB - Atopic dermatitis (AD) is a chronic inflammatory skin disease with the hallmark characteristics of pruritus, psychological stress, and sleep disturbance, all possibly associated with an increased risk of attention-deficit/hyperactivity disorder (ADHD). However, the etiology of the possible association between AD and ADHD is still not well understood. 2,4-dinitrochlorobenzene or corticosterone was used to evaluate the atopic symptom and its psychologic stress in the atopic mice model. Melatonin, corticotropin-releasing hormone, corticotropin-releasing hormone receptor, urocortin, proopiomelanocortin, adrenocorticotropic hormone, corticosterone, cAMP, cAMP response element-binding protein, dopamine and noradrenaline were analyzed spectrophotometrically, and the expression of dopamine beta-hydroxylase and tyrosine hydroxylase were measured by Western blotting or immunohistochemistry. AD-related psychological stress caused an increase in the levels of dopamine beta-hydroxylase and tyrosine hydroxylase, degradation of melatonin, hyper-activity of the hypothalamic-pituitary-adrenal axis, and dysregulation of dopamine and noradrenaline levels (ADHD phenomena) in the locus coeruleus, prefrontal cortex, and striatum of the AD mouse brain. Notably, melatonin administration inhibited the development of ADHD phenomena and their-related response in the mouse model. This study demonstrated that AD related psychological stress increased catecholamine dysfunction and accelerated the development of psychiatric comorbidities, such as ADHD. PMID- 30297830 TI - Chlorophyll a/b binding-specificity in water-soluble chlorophyll protein. AB - We altered the chlorophyll (Chl) binding sites in various versions of water soluble chlorophyll protein (WSCP) by amino acid exchanges to alter their preferences for either Chl a or Chl b. WSCP is ideally suited for this mutational analysis since it forms a tetrameric complex with only four identical Chl binding sites. A loop of 4-6 amino acids is responsible for Chl a versus Chl b selectivity. We show that a single amino acid exchange within this loop changes the relative Chl a/b affinities by a factor of 40. We obtained crystal structures of this WSCP variant binding either Chl a or Chl b. The Chl binding sites in these structures were compared with those in the major light-harvesting complex (LHCII) of the photosynthetic apparatus in plants to search for similar structural features involved in Chl a/b binding specificity. PMID- 30297831 TI - NIN interacts with NLPs to mediate nitrate inhibition of nodulation in Medicago truncatula. AB - Legume plants can assimilate inorganic nitrogen and have access to fixed nitrogen through symbiotic interaction with diazotrophic bacteria called rhizobia. Symbiotic nitrogen fixation is an energy-consuming process and is strongly inhibited when sufficient levels of fixed nitrogen are available, but the molecular mechanisms governing this regulation are largely unknown. The transcription factor nodule inception (NIN) is strictly required for nodulation and belongs to a family of NIN-like proteins (NLPs), which have been implicated in the regulation of nitrogen homeostasis in Arabidopsis. Here, we show that mutation or downregulation of NLP genes prevents nitrate inhibition of infection, nodule formation and nitrogen fixation. We find that NIN and NLPs physically interact through their carboxy-terminal PB1 domains. Furthermore, we find that NLP1 is required for the expression of nitrate-responsive genes and that nitrate triggers NLP1 re-localization from the cytosol to the nucleus. Finally, we show that NLP1 can suppress NIN activation of CRE1 expression in Nicotiana benthamiana and Medicago truncatula. Our findings highlight a central role for NLPs in the suppression of nodulation by nitrate. PMID- 30297829 TI - Notch1 regulates the initiation of metastasis and self-renewal of Group 3 medulloblastoma. AB - Medulloblastoma is the most common malignant brain tumor of childhood. Group 3 medulloblastoma, the most aggressive molecular subtype, frequently disseminates through the leptomeningeal cerebral spinal fluid (CSF) spaces in the brain and spinal cord. The mechanism of dissemination through the CSF remains poorly understood, and the molecular pathways involved in medulloblastoma metastasis and self-renewal are largely unknown. Here we show that NOTCH1 signaling pathway regulates both the initiation of metastasis and the self-renewal of medulloblastoma. We identify a mechanism in which NOTCH1 activates BMI1 through the activation of TWIST1. NOTCH1 expression and activity are directly related to medulloblastoma metastasis and decreased survival rate of tumor-bearing mice. Finally, medulloblastoma-bearing mice intrathecally treated with anti-NRR1, a NOTCH1 blocking antibody, present lower frequency of spinal metastasis and higher survival rate. These findings identify NOTCH1 as a pivotal driver of Group 3 medulloblastoma metastasis and self-renewal, supporting the development of therapies targeting this pathway. PMID- 30297832 TI - Simple ruthenium-catalyzed reductive amination enables the synthesis of a broad range of primary amines. AB - The production of primary benzylic and aliphatic amines, which represent essential feedstocks and key intermediates for valuable chemicals, life science molecules and materials, is of central importance. Here, we report the synthesis of this class of amines starting from carbonyl compounds and ammonia by Ru catalyzed reductive amination using H2. Key to success for this synthesis is the use of a simple RuCl2(PPh3)3 catalyst that empowers the synthesis of >90 various linear and branched benzylic, heterocyclic, and aliphatic amines under industrially viable and scalable conditions. Applying this catalyst, -NH2 moiety has been introduced in functionalized and structurally diverse compounds, steroid derivatives and pharmaceuticals. Noteworthy, the synthetic utility of this Ru catalyzed amination protocol has been demonstrated by upscaling the reactions up to 10 gram-scale syntheses. Furthermore, in situ NMR studies were performed for the identification of active catalytic species. Based on these studies a mechanism for Ru-catalyzed reductive amination is proposed. PMID- 30297833 TI - Mannich base limits Candida albicans virulence by inactivating Ras-cAMP-PKA pathway. AB - Mannich bases and its derivatives are regarded as supreme pharmacophores in therapeutics. The study investigates the antimycotic potential of Mannich bases, 1-((1H-benzimidazol-1-yl) methyl) urea (C1) and 1-((3-hydroxynapthalen-2-yl) methyl) thiourea (C2), against Candida albicans. Biofilm and hyphal inhibitory activities of the Mannich bases were tested by crystal violet quantification, fluorescence imaging cAMP rescue, qRT PCR, and by molecular docking analysis. The compounds inhibited the biofilms of C. albicans and restrained the filamentation abilities of the pathogen. Structure-activity relationship studies revealed that the presence of urea or thiourea moiety in the tail section is essential for interacting with adenylate cyclase (AC). The Mannich bases seemed to block Ras cAMP-PKA pathway by inhibiting second messenger activity required for hyphal induction and biofilm formation. In conclusion, the study warrants point-of-care testing of C1/C2 and provides a starting point for deriving several structurally modified Mannich bases which might plausibly replace the prevailing antimycotic drugs in future.

PMID- 30297834 TI - Effect of a butyrate-fortified milk replacer on gastrointestinal microbiota and products of fermentation in artificially reared dairy calves at weaning. AB - Enrichment of calf diets with exogenous butyrate has shown promise as a promotor of calf growth and intestinal development. However, the impact of dietary derived butyrate on the gut microbiota and their potential role, in turn, as mediators of its effect on calf growth and development is not known. Here, the effects of butyrate supplementation on rumen and hindgut microbiota and fermentation profiles were assessed in 16 Holstein-Friesian bull calves randomly assigned to one of two groups: Control (CON) fed conventional milk replacer or Sodium Butyrate (SB - added to milk replacer) from days 7 to 56 of life. In the colon, total short chain fatty acid (SCFA), propionate and acetate concentrations were increased by SB (P < 0.05). 16S rRNA gene amplicon sequencing showed cecal abundance of butyrate producers Butyrivibrio and Shuttleworthia were decreased by SB (P < 0.05), while that of the propionate producer Phascolarctobacterium was higher (P < 0.05). Mogibacterium is associated with impaired gut health and was reduced in the cecum of SB calves (P < 0.05). These data show that the beneficial effects of SB on growth and performance occur in tandem with changes in the abundance of important SCFA producing and health-associated bacteria in the hindgut in milk-fed calves. PMID- 30297836 TI - Haplosaurus computes protein haplotypes for use in precision drug design. AB - Selecting the most appropriate protein sequences is critical for precision drug design. Here we describe Haplosaurus, a bioinformatic tool for computation of protein haplotypes. Haplosaurus computes protein haplotypes from pre-existing chromosomally-phased genomic variation data. Integration into the Ensembl resource provides rapid and detailed protein haplotypes retrieval. Using Haplosaurus, we build a database of unique protein haplotypes from the 1000 Genomes dataset reflecting real-world protein sequence variability and their prevalence. For one in seven genes, their most common protein haplotype differs from the reference sequence and a similar number differs on their most common haplotype between human populations. Three case studies show how knowledge of the range of commonly encountered protein forms predicted in populations leads to insights into therapeutic efficacy. Haplosaurus and its associated database is expected to find broad applications in many disciplines using protein sequences and particularly impactful for therapeutics design. PMID- 30297837 TI - Formation of the beta-barrel assembly machinery complex in lipid bilayers as seen by solid-state NMR. AB - The beta-barrel assembly machinery (BAM) is a pentameric complex (BamA-E), which catalyzes the essential process of beta-barrel protein insertion into the outer membrane of E. coli. Thus far, a detailed understanding of the insertion mechanism has been elusive but recent results suggest that local protein motion, in addition to the surrounding membrane environment, may be of critical relevance. We have devised a high-sensitivity solid-state NMR approach to directly probe protein motion and the structural changes associated with BAM complex assembly in lipid bilayers. Our results reveal how essential BamA domains, such as the interface formed by the polypeptide transport associated domains P4 and P5 become stabilized after complex formation and suggest that BamA beta-barrel opening and P5 reorientation is directly related to complex formation in membranes. Both the lateral gate, as well as P5, exhibit local dynamics, a property that could play an integral role in substrate recognition and insertion. PMID- 30297838 TI - C16-ceramide is a natural regulatory ligand of p53 in cellular stress response. AB - Ceramides are important participants of signal transduction, regulating fundamental cellular processes. Here we report the mechanism for activation of p53 tumor suppressor by C16-ceramide. C16-ceramide tightly binds within the p53 DNA-binding domain (Kd ~ 60 nM), in close vicinity to the Box V motif. This interaction is highly selective toward the ceramide acyl chain length with its C10 atom being proximal to Ser240 and Ser241. Ceramide binding stabilizes p53 and disrupts its complex with E3 ligase MDM2 leading to the p53 accumulation, nuclear translocation and activation of the downstream targets. This mechanism of p53 activation is fundamentally different from the canonical p53 regulation through protein-protein interactions or posttranslational modifications. The discovered mechanism is triggered by serum or folate deprivation implicating it in the cellular response to nutrient/metabolic stress. Our study establishes C16 ceramide as a natural small molecule activating p53 through the direct binding. PMID- 30297839 TI - An Evolutionarily Conserved Mesodermal Enhancer in Vertebrate Zic3. AB - Zic3 encodes a zinc finger protein essential for the development of meso ectodermal tissues. In mammals, Zic3 has important roles in the development of neural tube, axial skeletons, left-right body axis, and in maintaining pluripotency of ES cells. Here we characterized cis-regulatory elements required for Zic3 expression. Enhancer activities of human-chicken-conserved noncoding sequences around Zic1 and Zic3 were screened using chick whole-embryo electroporation. We identified enhancers for meso-ectodermal tissues. Among them, a mesodermal enhancer (Zic3-ME) in distant 3' flanking showed robust enhancement of reporter gene expression in the mesodermal tissue of chicken and mouse embryos, and was required for mesodermal Zic3 expression in mice. Zic3-ME minimal core region is included in the DNase hypersensitive region of ES cells, mesoderm, and neural progenitors, and was bound by T (Brachyury), Eomes, Lef1, Nanog, Oct4, and Zic2. Zic3-ME is derived from an ancestral sequence shared with a sequence encoding a mitochondrial enzyme. These results indicate that Zic3-ME is an integrated cis-regulatory element essential for the proper expression of Zic3 in vertebrates, serving as a hub for a gene regulatory network including Zic3. PMID- 30297840 TI - A global strategy to mitigate the environmental impact of China's ruminant consumption boom. AB - Rising demand for ruminant meat and dairy products in developing countries is expected to double anthropogenic greenhouse gas and ammonia emissions from livestock by 2050. Mitigation strategies are urgently needed to meet demand while minimizing environmental impacts. Here, we develop scenarios for mitigating emissions under local vs global supply policies using data from 308 livestock farms across mainland China, where emissions intensities are ~50% higher than those in developed nations. Intensification of domestic production and globalized expansion through increased trade result in reductions in global emissions by nearly 30% over a business-as-usual scenario, but at the expense of trading partners absorbing the associated negative externalities of environmental degradation. Only adoption of a mixed strategy combining global best-practice in sustainable intensification of domestic production, with increased green-source trading as a short-term coping strategy, can meet 2050 demand while minimizing the local and global environmental footprint of China's ruminant consumption boom. PMID- 30297841 TI - Tuneable poration: host defense peptides as sequence probes for antimicrobial mechanisms. AB - The spread of antimicrobial resistance stimulates discovery strategies that place emphasis on mechanisms circumventing the drawbacks of traditional antibiotics and on agents that hit multiple targets. Host defense peptides (HDPs) are promising candidates in this regard. Here we demonstrate that a given HDP sequence intrinsically encodes for tuneable mechanisms of membrane disruption. Using an archetypal HDP (cecropin B) we show that subtle structural alterations convert antimicrobial mechanisms from native carpet-like scenarios to poration and non porating membrane exfoliation. Such distinct mechanisms, studied using low- and high-resolution spectroscopy, nanoscale imaging and molecular dynamics simulations, all maintain strong antimicrobial effects, albeit with diminished activity against pathogens resistant to HDPs. The strategy offers an effective search paradigm for the sequence probing of discrete antimicrobial mechanisms within a single HDP. PMID- 30297842 TI - ATR/Chk1 signaling induces autophagy through sumoylated RhoB-mediated lysosomal translocation of TSC2 after DNA damage. AB - DNA damage can induce autophagy; however, the underlying mechanism remains largely unknown. Here we report that DNA damage leads to autophagy through ATR/Chk1/RhoB-mediated lysosomal recruitment of TSC complex and subsequent mTORC1 inhibition. DNA damage caused by ultraviolet light (UV) or alkylating agent methyl methanesulphonate (MMS) results in phosphorylation of small GTPase RhoB by Chk1. Phosphorylation of RhoB enhances its interaction with the TSC2, and promotes its sumoylation by PIAS1, which is required for RhoB/TSC complex to translocate to lysosomes. As a result, mTORC1 is inhibited, and autophagy is activated. Knockout of RhoB severely attenuates lysosomal translocation of TSC complex and the DNA damage-induced autophagy. Reintroducing wild-type but not sumoylation-resistant RhoB into RhoB-/- cells restores the onset of autophagy. Hence, our study identifies a molecular mechanism for translocation of TSC complex to lysosomes in response to DNA damage, which depends on ATR/Chk1 mediated RhoB phosphorylation and sumoylation. PMID- 30297843 TI - Solution processes for ultrabroadband and omnidirectional graded-index glass lenses with near-zero reflectivity in high concentration photovoltaics. AB - Concentrator photovoltaic (CPV) systems, where incident direct solar radiation is tightly concentrated onto high-efficiency multi-junction solar cells by geometric optical elements, exhibit the highest efficiencies in converting the sun's energy into electric power. Their energy conversion efficiencies are greatly limited, however, due to Fresnel reflection losses occurring at three air/optics interfaces in the most sophisticated dual-stage CPV platforms. This paper describes a facile one-step wet-etching process to create a nanoporous surface with a graded-index profile on both flat and curved glasses, with capabilities of achieving ~99% average transmission efficiency in a wide wavelength range from 380 nm to 1.3 um and for a wide range of incident angles up to +/-40 degrees regardless of the polarization state of incident sunlight. The simplicity of the etching process remarkably increases their versatility in various optical elements that require unconventional form factors such as Fresnel lenses and microlens arrays, and/or demanding curvatures along with much reduced dimensions such as ball lenses. Etched glass surfaces on two-stage optical concentrating systems yield enhancements in total optical transmission efficiencies by 13.8% and in the photocurrent by 14.3%, as experimentally determined by measurements on microscale triple-junction solar cells. The presented strategy can be widely adapted in a variety of applications such as image sensors, display systems, and other optoelectronic devices. PMID- 30297844 TI - Direct protein-lipid interactions shape the conformational landscape of secondary transporters. AB - Secondary transporters undergo structural rearrangements to catalyze substrate translocation across the cell membrane - yet how such conformational changes happen within a lipid environment remains poorly understood. Here, we combine hydrogen-deuterium exchange mass spectrometry (HDX-MS) with molecular dynamics (MD) simulations to understand how lipids regulate the conformational dynamics of secondary transporters at the molecular level. Using the homologous transporters XylE, LacY and GlpT from Escherichia coli as model systems, we discover that conserved networks of charged residues act as molecular switches that drive the conformational transition between different states. We reveal that these molecular switches are regulated by interactions with surrounding phospholipids and show that phosphatidylethanolamine interferes with the formation of the conserved networks and favors an inward-facing state. Overall, this work provides insights into the importance of lipids in shaping the conformational landscape of an important class of transporters. PMID- 30297845 TI - Enhanced validation of antibodies for research applications. AB - There is a need for standardized validation methods for antibody specificity and selectivity. Recently, five alternative validation pillars were proposed to explore the specificity of research antibodies using methods with no need for prior knowledge about the protein target. Here, we show that these principles can be used in a streamlined manner for enhanced validation of research antibodies in Western blot applications. More than 6,000 antibodies were validated with at least one of these strategies involving orthogonal methods, genetic knockdown, recombinant expression, independent antibodies, and capture mass spectrometry analysis. The results show a path forward for efforts to validate antibodies in an application-specific manner suitable for both providers and users.

AB - Second phase strengthening has been applied to high entropy alloys (HEAs) for optimizing mechanical properties. In this study, by conducting mechanical testing of a eutectic dual-phase AlCoCrFeNi HEA with homogenous distribution of body centered cubic (BCC) and face-centered cubic (FCC) lamellar phases inside a transmission electron microscope, we found that although BCC was truly the hard phase, decreasing the proportion of BCC phase in fact increased the strength due to the existence of chemically disordered semi-coherent phase boundaries, which acted as potent impediments to dislocation motion resulting in dense dislocation storage in FCC phases. Moreover, the difficulty in dislocation glide caused massive cross-slip, and the interaction between primary slip arrays and cross slip systems during deformation increased the rate of dislocation accumulation by forming dislocation substructures, thus making the FCC phases exceptionally strong. Our findings not only revealed the underlying strengthening mechanism of eutectic dual-phase AlCoCrFeNi HEAs, but also shed light on new ways in further optimizing the mechanical properties of HEAs.

AB - Melanogenesis is the process of production of melanin pigments that are responsible for the colors of skin, eye, and hair and provide protection from ultraviolet radiation. However, excessive levels of melanin formation cause hyperpigmentation disorders such as freckles, melasma, and age spots. Liver X receptors (LXR) are nuclear oxysterol receptors belonging to the family of ligand activated transcription factors and physiological regulators of lipid and cholesterol metabolism. In the skin, activation of LXRs stimulates differentiation of keratinocytes and augments lipid synthesis in sebocytes. However, the function of LXRs in melanogenesis has not been clearly elucidated. In addition, although beauvericin, a well-known mycotoxin primarily isolated from several fungi, has various biological properties, its involvement in melanogenesis has not been reported. Therefore, in this study, we examined the effects of beauvericin on melanogenesis and its molecular mechanisms. Beauvericin decreased melanin content and tyrosinase activity without any cytotoxicity. Beauvericin also reduced protein levels of MITF, tyrosinase, TRP1, and TRP2. In addition, beauvericin suppressed cAMP-PKA-CREB signaling and upregulated expression of LXR-alpha, resulting in the suppression of p38 MAPK. Our results indicate that beauvericin attenuates melanogenesis by regulating both cAMP/PKA/CREB and LXR-alpha/p38 MAPK pathways, consequently leading to a reduction of melanin levels. PMID- 30297849 TI - Genome-scale fitness profile of Caulobacter crescentus grown in natural freshwater. AB - Bacterial genomes evolve in complex ecosystems and are best understood in this natural context, but replicating such conditions in the lab is challenging. We used transposon sequencing to define the fitness consequences of gene disruption in the bacterium Caulobacter crescentus grown in natural freshwater, compared with axenic growth in common laboratory media. Gene disruptions in amino-acid and nucleotide sugar biosynthesis pathways and in metabolic substrate transport machinery impaired fitness in both lake water and defined minimal medium relative to complex peptone broth. Fitness in lake water was enhanced by insertions in genes required for flagellum biosynthesis and reduced by insertions in genes involved in biosynthesis of the holdfast surface adhesin. We further uncovered numerous hypothetical and uncharacterized genes for which disruption impaired fitness in lake water, defined minimal medium, or both. At the genome scale, the fitness profile of mutants cultivated in lake water was more similar to that in complex peptone broth than in defined minimal medium. Microfiltration of lake water did not significantly affect the terminal cell density or the fitness profile of the transposon mutant pool, suggesting that Caulobacter does not strongly interact with other microbes in this ecosystem on the measured timescale. Fitness of select mutants with defects in cell surface biosynthesis and environmental sensing were significantly more variable across days in lake water than in defined medium, presumably owing to day-to-day heterogeneity in the lake environment. This study reveals genetic interactions between Caulobacter and a natural freshwater environment, and provides a new avenue to study gene function in complex ecosystems.

PMID- 30297847 TI - Functionalization of gold-nanoparticles by the Clostridium perfringens enterotoxin C-terminus for tumor cell ablation using the gold nanoparticle mediated laser perforation technique. AB - A recombinant produced C-terminus of the C. perfringens enterotoxin (C-CPE) was conjugated to gold nanoparticles (AuNPs) to produce a C-CPE-AuNP complex (C-CPE AuNP). By binding to claudins, the C- CPE should allow to target the AuNPs onto the claudin expressing tumor cells for a subsequent cell killing by application of the gold nanoparticle-mediated laser perforation (GNOME-LP) technique. Using qPCR and immunocytochemistry, we identified the human Caco-2, MCF-7 and OE-33 as well as the canine TiHoDMglCarc1305 as tumor cells expressing claudin-3, -4 and 7. Transepithelial electrical resistance (TEER) measurements of Caco-2 cell monolayer showed that the recombinant C-CPE bound to the claudins. GNOME-LP at a laser fluence of 60 mJ/cm2 and a scanning speed of 0.5 cm/s specifically eliminated more than 75% of claudin expressing human and canine cells treated with C-CPE-AuNP. The same laser fluence did not affect the cells when non functionalized AuNPs were used. Furthermore, most of the claudin non-expressing cells treated with C-CPE-AuNP were not killed by GNOME-LP. Additionally, application of C-CPE-AuNP to spheroids formed by MCF-7 and OE-33 cells grown in Matrigel reduced spheroid area. The results demonstrate that specific ablation of claudin expressing tumor cells is efficiently increased by activated C-CPE functionalized AuNPs using optical methods. PMID- 30297852 TI - Marine Carbonates in the Mantle Source of Oceanic Basalts: Pb Isotopic Constraints. AB - For almost fifty years, geochemists have been interpreting the clues from Pb isotopic ratios concerning mantle composition and evolution separately. The Pb isotopes of ocean island basalts (OIB) indicate that their mantle source is heterogeneous, most likely due to the presence of end-components derived from recycled crust and sediment. Some OIB have unusually high 206Pb/204Pb coming from one of the end-components with a long time-integrated high 238U/204Pb or MU (HIMU). Most OIB and many mid-ocean ridge basalts (MORB) also have high 206Pb/204Pb, indicating a HIMU-like source. Moreover, measured 232Th/238U (kappa) for most MORB are lower than those deduced from their 208Pb/204Pb and 206Pb/204Pb. Such high MU and low kappa features of oceanic basalts are inconsistent with the known geochemical behavior of U, Pb and Th and temporal evolution of the mantle; these have been respectively termed the 1st and 2nd Pb paradox. Here we show that subducted marine carbonates can be a source for HIMU and a solution to the Pb paradoxes. The results are consistent with the predictions of the marine carbonate recycling hypothesis that posits the Pb isotopes of oceanic basalts indicate a common origin and/or magma generation process. PMID- 30297851 TI - Sparsened neuronal activity in an optogenetically activated olfactory glomerulus. AB - Glomeruli are the functional units of olfactory information processing but little remains known about their individual unit function. This is due to their widespread activation by odor stimuli. We expressed channelrhodopsin-2 in a single olfactory sensory neuron type, and used laser stimulation and simultaneous in vivo calcium imaging to study the responses of a single glomerulus to optogenetic stimulation. Calcium signals in the neuropil of this glomerulus were representative of the sensory input and nearly identical if evoked by intensity matched odor and laser stimuli. However, significantly fewer glomerular layer interneurons and olfactory bulb output neurons (mitral cells) responded to optogenetic versus odor stimuli, resulting in a small and spatially compact optogenetic glomerular unit response. Temporal features of laser stimuli were represented with high fidelity in the neuropil of the glomerulus and the mitral cells, but not in interneurons. Increases in laser stimulus intensity were encoded by larger signal amplitudes in all compartments of the glomerulus, and by the recruitment of additional interneurons and mitral cells. No spatial expansion of the glomerular unit response was observed in response to stronger input stimuli. Our data are among the first descriptions of input-output transformations in a selectively activated olfactory glomerulus. PMID- 30297854 TI - Berry phase theory of planar Hall effect in topological insulators. AB - The appearance of negative longitudinal magnetoresistance (LMR) in topological semimetals such as Weyl and Dirac semimetals is understood as an effect of chiral anomaly, whereas such an anomaly is not well-defined in topological insulators. Nevertheless, it has been shown recently in both theory and experiments that nontrivial Berry phase effects can give rise to negative LMR in topological insulators even in the absence of chiral anomaly. In this paper, we present a quasi-classical theory of another intriguing phenomenon in topological insulators - also ascribed to chiral anomaly in Weyl and Dirac semimetals- the so-called planar Hall effect (PHE). PHE implies the appearance of a transverse voltage in the plane of applied non-parallel electric and magnetic fields, in a configuration in which the conventional Hall effect vanishes. Starting from Boltzmann transport equations we derive the expressions for PHE and LMR in topological insulators in the bulk conduction limit, and show the important role played by orbital magnetic moment. Our theoretical results for magnetoconductance with non-parallel electric and magnetic fields predict detailed experimental signatures in topological insulators - specifically of planar Hall effect - that can be observed in experiments. PMID- 30297853 TI - A Natural Deep Eutectic Solvent Formulated to Stabilize beta-Lactam Antibiotics. AB - beta-lactam antibiotics, such as penicillin share a very unstable chemical structure. In water-based solutions, such as those used for clinical applications, the beta-lactam ring is readily opened due to a nucleophilic or electrophilic attack, leading to the loss of antimicrobial activity. Since the achievement and maintenance of optimum therapeutic levels of beta-lactam antibiotics is critical for the resolution of many infectious clinical situations, and to avoid antibiotic resistance generation, the design of new non aqueous dosage forms is urgent. Recently, natural deep eutectic solvents (NADES) have emerged as alternative non-toxic and non-aqueous solvents for different biomedical applications. In this work, we formulated and characterized a NADES composed by betaine and urea (BU). Using this solvent, we evaluated the stability of clavulanic acid (CLV) and imipenem (IMP) and characterized their antimicrobial activities calculating the minimal inhibitory concentration. Characterization of BU solvent by infrared spectroscopy (IR) and nuclear magnetic resonance spectroscopy (NMR) indicated that the obtained solvent has a microstructure mainly based on hydrogen bonding interactions and water addition strongly affects its dynamic. The stability of beta-lactam antibiotic IMP and CLV using this solvent was increased by 7 fold and 2.5 fold respectively compared to water when analysed seven days after being dissolved. Microbiological assays showed that antibacterial activity at day seven was significantly decreased for both CLV and IMP when dissolved in water, while no change in their antibacterial properties was observed when antibiotics were dissolved in BU. The increased stability of IMP and CLV in BU may be related to the inert behaviour of the solvent and the higher dynamic restriction that helps antibiotics to maintain a more stable conformation. These data suggest the potential use of BU as a solvent to prevent degradation of beta-lactam antibiotics. PMID- 30297855 TI - Hydrophobic alkyl chains substituted to the 8-position of cyclic nucleotides enhance activation of CNG and HCN channels by an intricate enthalpy - entropy compensation. AB - Cyclic nucleotide-gated (CNG) and hyperpolarization-activated cyclic nucleotide gated (HCN) channels are tetrameric non-specific cation channels in the plasma membrane that are activated by either cAMP or cGMP binding to specific binding domains incorporated in each subunit. Typical apparent affinities of these channels for these cyclic nucleotides range from several hundred nanomolar to tens of micromolar. Here we synthesized and characterized novel cAMP and cGMP derivatives by substituting either hydrophobic alkyl chains or similar-sized more hydrophilic heteroalkyl chains to the 8-position of the purine ring with the aim to obtain full agonists of higher potency. The compounds were tested in homotetrameric CNGA2, heterotetrameric CNGA2:CNGA4:CNGB1b and homotetrameric HCN2 channels. We show that nearly all compounds are full agonists and that longer alkyl chains systematically increase the apparent affinity, at the best more than 30 times. The effects are stronger in CNG than HCN2 channels which, however, are constitutively more sensitive to cAMP. Kinetic analyses reveal that the off-rate is significantly slowed by the hydrophobic alkyl chains. Molecular dynamics simulations and free energy calculations suggest that an intricate enthalpy - entropy compensation underlies the higher apparent affinity of the derivatives with the longer alkyl chains, which is shown to result from a reduced loss of configurational entropy upon binding. PMID- 30297857 TI - Illustrating the effect of viscoelastic additives on cavitation and turbulence with X-ray imaging. AB - The effect of viscoelastic additives on the topology and dynamics of the two phase flow arising within an axisymmetric orifice with a flow path constriction along its main axis has been investigated employing high-flux synchrotron radiation. X-ray Phase Contrast Imaging (XPCI) has been conducted to visualise the cavitating flow of different types of diesel fuel within the orifice. An additised blend containing Quaternary Ammonium Salt (QAS) additives with a concentration of 500 ppm has been comparatively examined against a pure (base) diesel compound. A high-flux, 12 keV X-ray beam has been utilised to obtain time resolved radiographs depicting the vapour extent within the orifice from two views (side and top) with reference to its main axis. Different test cases have been examined for both fuel types and for a range of flow conditions characterised by Reynolds number of 35500 and cavitation numbers (CN) lying in the range 3.0-7.7. It has been established that the behaviour of viscoelastic micelles in the regions of shear flow is not consistent depending on the cavitation regimes encountered. Namely, viscoelastic effects enhance vortical (string) cavitation, whereas hinder cloud cavitation. Furthermore, the use of additised fuel has been demonstrated to suppress the level of turbulence within the orifice. PMID- 30297856 TI - Identification of a Novel OX40L+ Dendritic Cell Subset That Selectively Expands Regulatory T cells. AB - We have previously shown GM-CSF derived bone-marrow dendritic cells (G-BMDCs) can induce the selective expansion of Tregs through the surface-bound molecule OX40L; however, the physiological role of this ex vivo derived DC subset remained to be elucidated. We determined GM-CSF administration to mice induced the generation of in vivo derived OX40L+ DCs, phenotypically similar to ex vivo OX40L+G-BMDCs, in the spleen, brachial lymph nodes and liver. The generation of OX40L+ DCs correlated with increased percentages of functionally suppressive Tregs in the spleen, brachial lymph nodes, and liver of GM-CSF treated mice. DCs from GM-CSF treated mice expanded Tregs in CD4+ T-cell co-cultures in an OX40L dependent manner, suggesting OX40L+ DCs may play a role in peripheral Treg homeostasis. Furthermore, comparing the transcriptome data of OX40L+ DCs to that of all immune cell types revealed OX40L+ DCs to be distinct from steady-state immune cells and, microarray analysis of OX40L+G-BMDCs and OX40L-G-BMDCs revealed higher expression of molecules that are associated with tolerogenic phenotype and could play important roles in the function of OX40L+ DCs. These findings suggest that OX40L+ DCs may represent a unique DC subset induced under inflammatory conditions that may play an essential role in maintaining Treg homeostasis. PMID- 30297858 TI - Metabolic abnormalities in adult T-cell leukemia/lymphoma and induction of specific leukemic cell death using photodynamic therapy. AB - Adult T-cell leukemia/lymphoma (ATL) is an aggressive T-cell neoplasm caused by human T-cell leukemia virus type I (HTLV-I). Therapeutic interventions have not been associated with satisfactory outcomes. We showed that the porphyrin metabolic pathway preferentially accumulates the endogenous photosensitive metabolite, protoporphyrin IX (PpIX) in ATL, after a short-term culture with 5 aminolevulinic acid (ALA). PpIX accumulated 10-100-fold more in ATL leukemic cells when compared to healthy peripheral blood mononuclear cells (PBMCs). Patient specimens showed dynamic changes in flow cytometry profiles during the onset and progression of ATL. Furthermore, 98.7% of ATL leukemic cell death in the ATL patient specimens could be induced with 10 min of visible light exposure, while 77.5% of normal PBMCs survived. Metabolomics analyses revealed that a specific stage of the metabolic pathway progressively deteriorated with HTLV-I infection and at the onset of ATL. Therefore, this method will be useful in diagnosing and identifying high-risk HTLV-I carriers with single cell resolutions. Photodynamic therapy in the circulatory system may be a potential treatment due to its highly-specific, non-invasive, safe, simultaneous, and repeatedly-treatable modalities. PMID- 30297860 TI - Increasing the distance between two monomers of topoisomerase IIbeta under the action of antitumor agent 4beta-sulfur-(benzimidazole) 4' demethylepipodophyllotoxin. AB - Topoisomerases II (Top2s) are a group of essential enzymes involved in replication, transcription, chromosome condensation, and segregation via altering DNA topology. The mechanism of the Top2s poisons such as etoposide (VP-16) was reported as stabilizing the Top2-DNA complex and engendering permanent DNA breakage. As the structurally similar compound of VP-16, a novel 4beta-sulfur substituted 4'-demethylepipodophyllotoxin (DMEP) derivative (compound C-Bi) with superior antitumor activity was developed in our previous study. To understand the structural basis of the compound action, the crystal structure (2.54 A) of human Top2 beta-isoform (hTop2beta) cleavage complexes stabilized by compound C Bi was determined. However, compound C-Bi was not visible in the crystal structure. Through the comparison of the structures of hTop2beta-DNA-etoposide ternary complex and hTop2beta-DNA binary complex, it could be observed that the distance between drug-binding sites Arg503 of the two monomers was 26.62 A in hTop2beta-DNA-etoposide ternary complex and 34.54 A in hTop2beta-DNA binary complex, respectively. Significant twist were observed in the DNA chains of binary complex. It suggested that compound C-Bi played antitumor roles through increasing spacing of hTop2beta monomers. The changes in hTop2beta structure further caused double changes in the torsional direction and migration distance of the DNA chains, resulting in impeding religation of DNA. PMID- 30297859 TI - Increased levels of circulating MMP3 correlate with severe rejection in face transplantation. AB - Face transplantation is a viable treatment option for carefully selected patients with devastating injuries to the face. However, acute rejection episodes occur in more than 80% of recipients in the first postoperative year. Unfortunately, neither a correlation between histological grades of rejection and anti-rejection treatment nor systemic surrogate markers of rejection in face transplantation are established in clinical routine. Therefore, we utilized next generation aptamer based SOMAscan proteomics platform for non-invasive rejection biomarker discovery. Longitudinal serum samples from face transplant recipients with long term follow-up were included in this study. From the 1,310 proteins analyzed by SOMAscan, a 5-protein signature (MMP3, ACY1, IL1R2, SERPINA4, CPB2) was able to discriminate severe rejection from both no-rejection and nonsevere rejection samples. Technical validation on ELISA platform showed high correlation with the SOMAscan data for the MMP3 protein (rs = 0.99). Additionally, MMP3 levels were significantly increased during severe rejection as compared to no-rejection (p = 0.0009) and nonsevere rejection (p = 0.0173) episodes. Pathway analyses revealed significant activation of the metallopeptidase activity during severe face transplant rejection. This pilot study demonstrates the feasibility of SOMAscan to identify non-invasive candidate biomarkers of rejection in face transplantation. Further validation in a larger independent patient cohort is needed. PMID- 30297861 TI - Separating sexual dimorphism from other morphological variation in a specimen complex of fossil marine reptiles (Reptilia, Ichthyosauriformes, Chaohusaurus). AB - The Early Triassic Chaohu Fauna from Anhui Province, China, contains the oldest record of Mesozoic marine reptiles, such as Cartorhynchus and Sclerocormus. Most specimens from the fauna belong to the ichthyosauriform Chaohusaurus, more specifically resembling C. chaoxianensis. However, a wide range of morphological variation exists within about 40 skeletons that have been prepared, likely reflecting mixed signals from both sexual and taxonomic differences. We test whether the sexual and taxonomic signals are separable based on quantification, aided by the knowledge of sexual dimorphism in extant marine tetrapods. There are two different suites of dimorphism that divide the specimens differently from each other yet consistently within each suite, resulting in four morphotypes in combination, likely representing two sexes of two taxa. Presumed males have larger 'organ of prehension' sensu Darwin, specifically limbs in the present case, for a given body length. This sexing criterion is supported by the only specimen of a gravid female, which belongs to the morphotype with short limbs. Males also have larger skulls for the trunk length compared to females. This study demonstrates that sexual and taxonomic signals are separable in fossil reptiles, with a sufficient sample size and careful analyses. PMID- 30297862 TI - Comparative transcriptomic profile of tolerogenic dendritic cells differentiated with vitamin D3, dexamethasone and rapamycin. AB - Tolerogenic dendritic cell (tolDC)-based therapies have become a promising approach for the treatment of autoimmune diseases by their potential ability to restore immune tolerance in an antigen-specific manner. However, the broad variety of protocols used to generate tolDC in vitro and their functional and phenotypical heterogeneity are evidencing the need to find robust biomarkers as a key point towards their translation into the clinic, as well as better understanding the mechanisms involved in the induction of immune tolerance. With that aim, in this study we have compared the transcriptomic profile of tolDC induced with either vitamin D3 (vitD3-tolDC), dexamethasone (dexa-tolDC) or rapamycin (rapa-tolDC) through a microarray analysis in 5 healthy donors. The results evidenced that common differentially expressed genes could not be found for the three different tolDC protocols. However, individually, CYP24A1, MUCL1 and MAP7 for vitD3-tolDC; CD163, CCL18, C1QB and C1QC for dexa-tolDC; and CNGA1 and CYP7B1 for rapa-tolDC, constituted good candidate biomarkers for each respective cellular product. In addition, a further gene set enrichment analysis of the data revealed that dexa-tolDC and vitD3-tolDC share several immune regulatory and anti-inflammatory pathways, while rapa-tolDC seem to be playing a totally different role towards tolerance induction through a strong immunosuppression of their cellular processes. PMID- 30297864 TI - Generation of two-cell cloned embryos from mouse faecal cell. AB - Cloning animals using nuclear transfer (NT) provides the opportunity to preserve endangered species. However, there are risks associated with the collection of donor cells from a body, which may cause accidental death of the animal. Here, we tried to collect faeces-derived cells and examined the usability of those nuclei as a donor for NT. A relatively large number of cells could be collected from GFP Tg mouse faeces by this method. After NT, only 4.2% of the reconstructed oocytes formed pseudo-pronucleus. This rate increased up to 25% when GFP and Hoechst were used as a marker to select better cells. However, the reconstructed oocytes/embryos showed several abnormalities, such as shrunken nuclear membranes and abnormal distribution of tubulin, and none of them developed beyond one-cell stage embryos. These developmental failures were caused by not only toxic substances derived from faeces but also intrinsic DNA damage of donor cell nuclei. However, when the serial NT was performed, some of the cloned embryos could develop to the two-cell stage. This method may remove toxic substances and enhance DNA repair in the oocyte cytoplasm. Thus, these results indicate that faeces cells might be useful for the conservation of endangered species when technical improvements are achieved. PMID- 30297863 TI - Genetic and mechanistic basis for APOBEC3H alternative splicing, retrovirus restriction, and counteraction by HIV-1 protease. AB - Human APOBEC3H (A3H) is a single-stranded DNA cytosine deaminase that inhibits HIV-1. Seven haplotypes (I-VII) and four splice variants (SV154/182/183/200) with differing antiviral activities and geographic distributions have been described, but the genetic and mechanistic basis for variant expression and function remains unclear. Using a combined bioinformatic/experimental analysis, we find that SV200 expression is specific to haplotype II, which is primarily found in sub-Saharan Africa. The underlying genetic mechanism for differential mRNA splicing is an ancient intronic deletion [del(ctc)] within A3H haplotype II sequence. We show that SV200 is at least fourfold more HIV-1 restrictive than other A3H splice variants. To counteract this elevated antiviral activity, HIV-1 protease cleaves SV200 into a shorter, less restrictive isoform. Our analyses indicate that, in addition to Vif-mediated degradation, HIV-1 may use protease as a counter defense mechanism against A3H in >80% of sub-Saharan African populations.

PMID- 30297865 TI - Identification of pharmacological inhibitors of conventional protein secretion. AB - The retention using selective hooks (RUSH) system allows to withhold a fluorescent biosensor such as green fluorescent protein (GFP) fused to a streptavidin-binding peptide (SBP) by an excess of streptavidin molecules that are addressed to different subcellular localizations. Addition of biotin competitively disrupts this interaction, liberating the biosensor from its hook. We constructed a human cell line co-expressing soluble secretory-SBP-GFP (ss-SBP GFP) and streptavidin within the endoplasmic reticulum (ER) lumen and then used this system to screen a compound library for inhibitors of the biotin-induced release of ss-SBP-GFP via the conventional Golgi-dependent protein secretion pathway into the culture supernatant. We identified and validated a series of molecularly unrelated drugs including antianginal, antidepressant, anthelmintic, antipsychotic, antiprotozoal and immunosuppressive agents that inhibit protein secretion. These compounds vary in their capacity to suppress protein synthesis and to compromise ER morphology and Golgi integrity, as well as in the degree of reversibility of such effects. In sum, we demonstrate the feasibility and utility of a novel RUSH-based phenotypic screening assay. PMID- 30297867 TI - ALPK1: innate attraction to the sweetness of bacteria. PMID- 30297868 TI - Pyruvate kinase M2 regulates homologous recombination-mediated DNA double-strand break repair. AB - Resistance to genotoxic therapies is a primary cause of treatment failure and tumor recurrence. The underlying mechanisms that activate the DNA damage response (DDR) and allow cancer cells to escape the lethal effects of genotoxic therapies remain unclear. Here, we uncover an unexpected mechanism through which pyruvate kinase M2 (PKM2), the highly expressed PK isoform in cancer cells and a master regulator of cancer metabolic reprogramming, integrates with the DDR to directly promote DNA double-strand break (DSB) repair. In response to ionizing radiation and oxidative stress, ATM phosphorylates PKM2 at T328 resulting in its nuclear accumulation. pT328-PKM2 is required and sufficient to promote homologous recombination (HR)-mediated DNA DSB repair through phosphorylation of CtBP interacting protein (CtIP) on T126 to increase CtIP's recruitment at DSBs and resection of DNA ends. Disruption of the ATM-PKM2-CtIP axis sensitizes cancer cells to a variety of DNA-damaging agents and PARP1 inhibition. Furthermore, increased nuclear pT328-PKM2 level is associated with significantly worse survival in glioblastoma patients. Combined, these data advocate the use of PKM2 targeting strategies as a means to not only disrupt cancer metabolism but also inhibit an important mechanism of resistance to genotoxic therapies. PMID- 30297869 TI - Elimination of CD4lowHLA-G+ T cells overcomes castration-resistance in prostate cancer therapy. AB - Androgen deprivation therapy (ADT) is a main treatment for prostate cancer (PCa) but the disease often recurs and becomes castration-resistant in nearly all patients. Recent data implicate the involvement of immune cells in the development of this castration-resistant prostate cancer (CRPC). In particular, T cells have been found to be expanded in both PCa patients and mouse models shortly after androgen deprivation. However, whether or which of the T cell subtypes play an important role during the development of CRPC is unknown. Here we identified a novel population of CD4lowHLA-G+ T cells that undergo significant expansion in PCa patients after ADT. In mouse PCa models, a similar CD4low T cell population expands during the early stages of CRPC onset. These cells are identified as IL-4-expressing TH17 cells, and are shown to be associated with CRPC onset in patients and essential for the development of CRPC in mouse models. Mechanistically, CD4lowHLA-G+ T cells drive androgen-independent growth of prostate cancer cells by modulating the activity and migration of CD11blowF4/80hi macrophages. Furthermore, following androgen deprivation, elevated PGE2-EP2 signaling inhibited the expression of CD4 in thymocytes, and subsequently induced the polarization of CD4low naive T cells towards the IL-4-expressing TH17 phenotype via up-regulation of IL23R. Therapeutically, inactivating PGE2 signaling with celecoxib at a time when CD4lowHLA-G+ T cells appeared, but not immediately following androgen deprivation, dramatically suppressed the onset of CRPC. Collectively, our results indicate that an unusual population of CD4lowHLA G+ T cells is essential for the development of CRPC and point to a new therapeutic avenue of combining ADT with PGE2 inhibition for the treatment of prostate cancer. PMID- 30297870 TI - METTL3-mediated N6-methyladenosine mRNA modification enhances long-term memory consolidation. AB - The formation of long-term memory is critical for learning ability and social behaviors of humans and animals, yet its underlying mechanisms are largely unknown. We found that the efficacy of hippocampus-dependent memory consolidation is regulated by METTL3, an RNA N6-methyladenosine (m6A) methyltransferase, through promoting the translation of neuronal early-response genes. Such effect is exquisitely dependent on the m6A methyltransferase function of METTL3. Depleting METTL3 in mouse hippocampus reduces memory consolidation ability, yet unimpaired learning outcomes can be achieved if adequate training was given or the m6A methyltransferase function of METTL3 was restored. The abundance of METTL3 in wild-type mouse hippocampus is positively correlated with learning efficacy, and overexpression of METTL3 significantly enhances long-term memory consolidation. These findings uncover a direct role of RNA m6A modification in regulating long-term memory formation, and also indicate that memory efficacy difference among individuals could be compensated by repeated learning.

PMID- 30297872 TI - Temperature affects the biology of Schmidtea mediterranea. AB - Studies of tissue regeneration and host-pathogen interactions using the model planarian Schmidtea mediterranea have been performed at an experimental temperature of 19 degrees C. S. mediterranea planarians exposed to 19 degrees C 32 degrees C were observed for survival, mobility, feeding and regeneration for three months and elimination of the Staphylococcus aureus pathogen over six days. S. mediterranea planarians died at 30 degrees C-32 degrees C after 18 days of observation but tolerated temperatures of 19 degrees C up to 28 degrees C with non-significant differences in mobility and feeding behavior. Genetic malleability tested by RNAi feeding was still efficient at 26 degrees C and 28 degrees C. Concerning the immune capacity of planarians, we reported an exacerbation of the immune response in worms infected by S. aureus at 26 degrees C and 28 degrees C. These observations suggest a temperature modulation of planarian stem cells and illustrate the importance of modulating experimental temperature when using planarians as model organisms to study regeneration and immune response. PMID- 30297871 TI - A dynamic N6-methyladenosine methylome regulates intrinsic and acquired resistance to tyrosine kinase inhibitors. AB - N6-methyladenosine (m6A) on mRNAs is critical for various biological processes, yet whether m6A regulates drug resistance remains unknown. Here we show that developing resistant phenotypes during tyrosine kinase inhibitor (TKI) therapy depends on m6A reduction resulting from FTO overexpression in leukemia cells. This deregulated FTO-m6A axis pre-exists in naive cell populations that are genetically homogeneous and is inducible/reversible in response to TKI treatment. Cells with mRNA m6A hypomethylation and FTO upregulation demonstrate more TKI tolerance and higher growth rates in mice. Either genetic or pharmacological restoration of m6A methylation through FTO deactivation renders resistant cells sensitive to TKIs. Mechanistically, the FTO-dependent m6A demethylation enhances mRNA stability of proliferation/survival transcripts bearing m6A and subsequently leads to increased protein synthesis. Our findings identify a novel function for the m6A methylation in regulating cell fate decision and demonstrate that dynamic m6A methylome is an additional epigenetic driver of reversible TKI-tolerance state, providing a mechanistic paradigm for drug resistance in cancer.

AB - alpha-Ketoglutarate (alphaKG) is a key node in many important metabolic pathways. The alphaKG analog N-oxalylglycine (NOG) and its cell-permeable prodrug dimethyloxalylglycine (DMOG) are extensively used to inhibit alphaKG-dependent dioxygenases. However, whether NOG interference with other alphaKG-dependent processes contributes to its mode of action remains poorly understood. Here we show that, in aqueous solutions, DMOG is rapidly hydrolyzed, yielding methyloxalylglycine (MOG). MOG elicits cytotoxicity in a manner that depends on its transport by monocarboxylate transporter 2 (MCT2) and is associated with decreased glutamine-derived tricarboxylic acid-cycle flux, suppressed mitochondrial respiration and decreased ATP production. MCT2-facilitated entry of MOG into cells leads to sufficiently high concentrations of NOG to inhibit multiple enzymes in glutamine metabolism, including glutamate dehydrogenase. These findings reveal that MCT2 dictates the mode of action of NOG by determining its intracellular concentration and have important implications for the use of (D)MOG in studying alphaKG-dependent signaling and metabolism. PMID- 30297876 TI - Lead: a hidden "untested" risk in neonatal blood transfusion. AB - BACKGROUND: Neonates may be exposed to lead (Pb) through blood transfusions from donors. Pb exposure has neurological, cardiovascular, renal, and other adverse effects. The study aimed to (i) determine the blood lead levels (BLLs) in different blood product units (whole blood, packed red blood cells (pRBCs), platelets, and plasma transfused to neonates) and (ii) estimate the proportion of units with high BLLs. METHODS: Residual blood from blood bank bags that were used for neonatal transfusion were collected: 25 samples from each type of blood product except for whole blood (10 samples). The Pb analysis was performed using the atomic absorption method. The study was conducted at the Suez Canal University Hospital, Egypt. RESULTS: The mean of BLL in pRBCs, platelets, plasma, and whole blood were 136, 199, 108, and 130 ug/L, respectively; 60% contained Pb above 50 ug/L. The highest BLLs were in platelet units. CONCLUSIONS: The present study showed for the first time that platelets and plasma in addition to whole blood and pRBCs used for neonatal transfusions are sources of Pb. Re-evaluation of the guidelines is mandatory for the safety of the neonates. Long-term neurodevelopment assessment of neonates exposed to high Pb is warranted. PMID- 30297877 TI - Oxygen therapy of the newborn from molecular understanding to clinical practice. AB - Oxygen is one of the most critical components of life. Nature has taken billions of years to develop optimal atmospheric oxygen concentrations for human life, evolving from very low, peaking at 30% before reaching 20.95%. There is now increased understanding of the potential toxicity of both too much and too little oxygen, especially for preterm and asphyxiated infants and of the potential and lifelong impact of oxygen exposure, even for a few minutes after birth. In this review, we discuss the contribution of knowledge gleaned from basic science studies and their implication in the care and outcomes of the human infant within the first few minutes of life and afterwards. We emphasize current knowledge gaps and research that is needed to answer a problem that has taken Nature a considerably longer time to resolve. PMID- 30297878 TI - Fetal programming of neuropsychiatric disorders by maternal pregnancy depression: a systematic mini review. AB - BACKGROUND: Maternal depression complicates a large proportion of pregnancies. Current evidence shows numerous harmful effects on the offspring. Reviews, which include depression, concluded that stress has harmful effects on the offspring's outcomes neuro-cognitive development, temperament traits, and mental disorders. OBJECTIVE: This mini review of recent studies, sought to narrow the scope of exposure and identify studies specifically assessing prenatal depression and offspring neuropsychiatric outcomes. STUDY ELIGIBILITY CRITERIA: The review included longitudinal, cohort, cross-sectional, clinical, quasi-experimental, epidemiological, or intervention study designs published in English from 2014 to 2018. PARTICIPANTS: Study populations included mother-child dyads, mother-father child triads, mother-alternative caregiver-child triads, and family studies utilizing sibling comparisons. METHODS: We searched PubMED and Web of Science. Study inclusion and data extraction were based on standardized templates. The quality of evidence was assessed using the Newcastle-Ottawa Scale (NOS). RESULTS: Thirteen studies examining neuropsychiatric outcomes were included. We judged the evidence to be moderate to high quality. CONCLUSIONS: Our review supports that maternal prenatal depression is associated with neuropsychiatric adversities in children. IMPLICATIONS: Future investigations should unravel the biological underpinnings and target timely interventions as early in pregnancy as possible to prevent offspring neuropsychiatric harms. PMID- 30297879 TI - Erythropoietin serum levels, versus anaemia as risk factors for severe retinopathy of prematurity. AB - BACKGROUND: Preterm infants with anaemia are treated with recombinant human erythropoietin (rhEPO). It is debated whether rhEPO treatment is a risk factor for retinopathy of prematurity (ROP). We evaluated longitudinal EPO and haemoglobin levels, blood transfusions and neonatal morbidities as risk factors for severe ROP. METHOD: This prospective study included 78 Swedish infants, born <28 weeks gestational age (GA), screened for ROP. We tested serum EPO levels on postnatal days 1, 7, 14 and 28 and at postmenstrual ages 32, 36 and 40 weeks. Haemoglobin levels and blood transfusions were recorded during postnatal weeks 1 4. Anaemia was defined as haemoglobin <=110 g/L. RESULTS: During postnatal week 1, infants with severe ROP requiring treatment (28%) more frequently developed anaemia (42.9% versus 8.0%, P = 0.003) and had higher mean EPO levels (postnatal day 7: 14.2 versus 10.8 mIU/mL, P = 0.003) compared to infants with no or less severe ROP not requiring treatment. In multivariable analyses, GA and anaemia during week 1 remained significant risk factors, but elevated EPO level postnatal day 7 was no longer significant. CONCLUSIONS: Among infants born <28 weeks GA, anaemia during week 1 was a significant risk factor for severe ROP requiring treatment but not elevated EPO levels. PMID- 30297880 TI - Metabolomic profiles and development of metabolic risk during the pubertal transition: a prospective study in the ELEMENT Project. AB - OBJECTIVES: (1) Examine associations of a branched-chain amino acid (BCAA) metabolite pattern with metabolic risk across adolescence; (2) use Least Absolute Shrinkage and Selection Operator (LASSO) to identify novel metabolites of metabolic risk. METHODS: We used linear regression to examine associations of a BCAA score with change (?) in metabolic biomarkers over 5-year follow-up in 179 adolescents 8-14 years at baseline. Next, we applied LASSO, a regularized regression technique well suited for reduction of high-dimensional data, to identify metabolite predictors of ?biomarkers. RESULTS: In boys, the BCAA score corresponded with decreasing C-peptide, C-peptide-based insulin resistance (CP IR), total cholesterol (TC), and low-density-lipoprotein cholesterol (LDL). In pubertal girls, the BCAA pattern corresponded with increasing C-peptide and leptin. LASSO identified asparagine as a predictor of decreasing C-peptide (beta = -0.33) and CP-IR (beta = -0.012), and acetyl-carnitine (beta = 2.098), 4 hydroxyproline (beta = -0.050), ornithine (beta = -0.353), and alpha aminoisobutyric acid (beta = -0.793) as determinants of TC in boys. In girls, histidine was a negative determinant of TC (beta = -0.033). CONCLUSIONS: The BCAA pattern was associated with ?glycemia and ?lipids in a sex-specific manner. LASSO identified asparagine, which influences growth hormone secretion, as a determinant of decreasing C-peptide and CP-IR in boys, and metabolites on lipid metabolism pathways as determinants of decreasing cholesterol in both sexes. PMID- 30297881 TI - Increased CD3+ T cells with a low FOXP3+/CD8+ T cell ratio can predict anti-PD-1 therapeutic response in non-small cell lung cancer patients. AB - To determine whether tumor microenvironments affect the clinical response to anti PD-1 therapy in non-small cell lung cancer, we investigated the expression level of PD-L1 and tumor infiltrating lymphocytes and elucidate their predictive role. Thirty-eight pretreatment and two post-treatment specimens from 36 advanced, treatment-refractory non-small cell lung cancer patients who underwent PD-1 blockade therapy were analyzed. PD-L1 expression by tumor cells and the distribution of CD3, CD8, CD4, FOXP3 and PD-1 positive tumor infiltrating lymphocytes were immunohistochemically assessed and counted using digital image analyzer. CD3+ and CD8+ T cells were distributed more in PD-L1 positive group compared to PD-L1 negative group. Conversely, EGFR mutant group showed fewer CD3+ T cells than EGFR-naive group. The patients in the clinical benefit group with PD 1 blockade showed a higher number of CD3+, CD8+ T cells and a higher CD8+/CD3+ T cell ratio (p = 0.003, p = 0.001, and p = 0.042) and a lower FOXP3+/CD8+ T cell ratio compared to non-responders (p = 0.001). In multivariate logistic regression analysis, increased CD3+ T cell infiltration and low FOXP3+/CD8+ T cell ratio were found to be independent predictors of clinical benefit with PD-1 blockade (p = 0.014 and p = 0.03, respectively). Using receiver operating characteristic curves, levels of CD3+ T cells and FOXP3+/CD8+ T cell ratio that provide the best distinguishing point between responder versus non-responder to PD-1 blockade were 617.5/mm2 and 25%, respectively (p = 0.007 and p = 0.003). Considering that 1 mm2 is about 5 high power fields (HPF), a good response to the PD-1 blockade can be expected when the number of CD3 T cells is observed to be 120 per HPF and when CD8+ T cells and FOXP3+ T cells are present at a ratio greater than 4:1. Tumor infiltrating lymphocytes might become a promising biomarker as an independent predictive factor of response to PD-1 blockade that may also guide therapeutic decisions. PMID- 30297882 TI - The clinicopathologic features of chronic active Epstein-Barr virus infective enteritis. AB - Chronic active Epstein-Barr virus infective enteritis (CAEBV enteritis) is rare and has not been well described yet. Therefore, we reported the clinicopathologic features of 11 patients with chronic active Epstein-Barr virus infective enteritis and their differences from inflammatory bowel disease. The major clinical presentations of chronic active Epstein-Barr virus infective enteritis were intermittent fever over 39 degrees C (100%), diarrhea (73%), abdominal pain (64%), lymphadenopathy (64%), splenomegaly (64%), and hepatomegaly (27%). The main endoscopic findings included numerous shallow, small, and irregular ulcers, mainly involving colon and small intestine together, no cobble-like appearance, and longitudinal ulcers. Compared to inflammatory bowel disease patients, the frequency of intermittent fever, hepatomegaly, splenomegaly, lymphadenopathy, the value of C-reactive protein, and serum Epstein-Barr virus DNA (EBV DNA) were significantly higher in chronic active Epstein-Barr virus infective enteritis patients (p < 0.01). The histologic findings show transmural inflammation with extended lymphoid infiltration, fissuring ulcers, and intraepithelial lymphocytosis. But chronic active Epstein-Barr virus infective enteritis lacked granulomas and connective tissue changes such as neural hypertrophy and thickened muscularis mucosae. Three chronic active Epstein-Barr virus infective enteritis patients died within 5 years of disease onset, and those three patients have received total colectomy, two of them died within 1 month after surgery. In this study, clinicopathologic features have been summarized to better recognize chronic active Epstein-Barr virus infective enteritis. There are resemblances between chronic active Epstein-Barr virus infective enteritis and inflammatory bowel disease, but some symptoms, signs, and indexes like intermittent fever, hepatomegaly, splenomegaly, lymphadenopathy, and elevated C-reactive protein, Epstein-Barr virus DNA are characteristics to differentiate chronic active Epstein-Barr virus infective enteritis and inflammation. Histopathological features also help the discrimination. Serum Epstein-Barr virus DNA and intestinal tissue in situ hybridization for Epstein-Barr virus-encoded RNA are recommended to exclude chronic active Epstein-Barr virus infective enteritis. PMID- 30297883 TI - Discharge Performance of Zinc-Air Flow Batteries Under the Effects of Sodium Dodecyl Sulfate and Pluronic F-127. AB - Zinc-air batteries are a promising technology for large-scale electricity storage. However, their practical deployment has been hindered by some issues related to corrosion and passivation of the zinc anode in an alkaline electrolyte. In this work, anionic surfactant sodium dodecyl sulfate (SDS) and nonionic surfactant Pluronic F-127 (P127) are examined their applicability to enhance the battery performances. Pristine zinc granules in 7 M KOH, pristine zinc granules in 0-8 mM SDS/7 M KOH, pristine zinc granules in 0-1000 ppm P127/7 M KOH, and SDS coated zinc granules in 7 M KOH were examined. Cyclic voltammograms, potentiodynamic polarization, and electrochemical impedance spectroscopy confirmed that using 0.2 mM SDS or 100 ppm P127 effectively suppressed the anode corrosion and passivation. Nevertheless, direct coating SDS on the zinc anode showed adverse effects because the thick layer of SDS coating acted as a passivating film and blocked the removal of the anode oxidation product from the zinc surface. Furthermore, the performances of the zinc-air flow batteries were studied. Galvanostatic discharge results indicated that the improvement of discharge capacity and energy density could be sought by the introduction of the surfactants to the KOH electrolyte. The enhancement of specific discharge capacity for 30% and 24% was observed in the electrolyte containing 100 ppm P127 and 0.2 mM SDS, respectively. PMID- 30297885 TI - Extraction and liposome reconstitution of membrane proteins with their native lipids without the use of detergents. AB - Functional studies of membrane-bound channels, transporters or signal transducers require that the protein of interest resides in a membrane that separates two compartments. One approach that is commonly used to prepare these systems is to reconstitute the protein in liposomes. An intermediate step of this method is purification of the protein, which typically involves solubilization of the native membrane using detergent. The use of detergents often results in removal of lipids surrounding the protein, which may alter its structure and function. Here, we have employed a method for isolation of membrane proteins with a disc of their native lipids to develop an approach that allows transfer of the purified membrane protein to liposomes without the use of any detergents. PMID- 30297884 TI - An efficient and multiple target transgenic RNAi technique with low toxicity in Drosophila. AB - Being relatively simple and practical, Drosophila transgenic RNAi is the technique of top priority choice to quickly study genes with pleiotropic functions. However, drawbacks have emerged over time, such as high level of false positive and negative results. To overcome these shortcomings and increase efficiency, specificity and versatility, we develop a next generation transgenic RNAi system. With this system, the leaky expression of the basal promoter is significantly reduced, as well as the heterozygous ratio of transgenic RNAi flies. In addition, it has been first achieved to precisely and efficiently modulate highly expressed genes. Furthermore, we increase versatility which can simultaneously knock down multiple genes in one step. A case illustration is provided of how this system can be used to study the synthetic developmental effect of histone acetyltransferases. Finally, we have generated a collection of transgenic RNAi lines for those genes that are highly homologous to human disease genes. PMID- 30297886 TI - A comprehensive overview of genomic imprinting in breast and its deregulation in cancer. AB - Genomic imprinting plays an important role in growth and development. Loss of imprinting (LOI) has been found in cancer, yet systematic studies are impeded by data-analytical challenges. We developed a methodology to detect monoallelically expressed loci without requiring genotyping data, and applied it on The Cancer Genome Atlas (TCGA, discovery) and Genotype-Tissue expression project (GTEx, validation) breast tissue RNA-seq data. Here, we report the identification of 30 putatively imprinted genes in breast. In breast cancer (TCGA), HM13 is featured by LOI and expression upregulation, which is linked to DNA demethylation. Other imprinted genes typically demonstrate lower expression in cancer, often associated with copy number variation and aberrant DNA methylation. Downregulation in cancer frequently leads to higher relative expression of the (imperfectly) silenced allele, yet this is not considered canonical LOI given the lack of (absolute) re-expression. In summary, our novel methodology highlights the massive deregulation of imprinting in breast cancer. PMID- 30297888 TI - Evaluation of ENSO simulations in CMIP5 models: A new perspective based on percolation phase transition in complex networks. AB - In this study, the performance of CMIP5 models in simulating the El Nino-Southern Oscillation (ENSO) is evaluated by using a new metric based on percolation theory. The surface air temperatures (SATs) over the tropical Pacific Ocean are constructed as a SAT network, and the nodes within the network are linked if they are highly connected (e.g., high correlations). It has been confirmed from reanalysis datasets that the SAT network undergoes an abrupt percolation phase transition when the influences of the sea surface temperature anomalies (SSTAs) below are strong enough. However, from simulations of the CMIP5 models, most models are found incapable of capturing the observed phase transition at a proper critical point Pc. For the 15 considered models, four even miss the phase transition, indicating that the simulated SAT network is too stable to be significantly changed by the SSTA below. Only four models can be considered cautiously with some skills in simulating the observed phase transition of the SAT network. By comparing the simulated SSTA patterns with the node vulnerabilities, which is the chance of each node being isolated during a ENSO event, we find that the improperly simulated sea-air interactions are responsible for the missing of the observed percolation phase transition. Accordingly, a careful study of the sea-air couplers, as well as the atmospheric components of the CMIP5 models is suggested. Since the percolation phase transition of the SAT network is a useful phenomenon to indicate whether the ENSO impacts can be transferred remotely, it deserves more attention for future model development. PMID- 30297887 TI - MSCs inhibit tumor progression and enhance radiosensitivity of breast cancer cells by down-regulating Stat3 signaling pathway. AB - The acquisition of radioresistance by breast cancer cells during radiotherapy may lead to cancer recurrence and poor survival. Signal transducer and activator of transcription 3 (Stat3) is activated in breast cancer cells and, therefore, may be an effective target for overcoming therapeutic resistance. Mesenchymal stem cells (MSCs) have been investigated for use in cancer treatment. Here, we investigated the potential of MSC conditioned medium (MSC-CM) in sensitizing breast cancer to radiotherapy. It was found that MSC-CM could inhibit the level of activated Stat3, suppress cancer growth, and exhibit synergetic effects with radiation treatment in vitro and in vivo. Furthermore, MSC-CM reduced the ALDH positive cancer stem cells (CSCs) population, modulated several potential stem cell markers, and decreased tumor migration, as well as metastasis. These results demonstrate that MSC-CM suppresses breast cancer cells growth and sensitizes cancer cells to radiotherapy through inhibition of the Stat3 signaling pathway, thus, providing a novel strategy for breast cancer therapy by overcoming radioresistance.

AB - Non-adherence to medication is an important health care problem, especially in the treatment of chronic conditions. Injectable long-acting (LA) formulations of antiretrovirals (ARVs) represent a viable alternative to improve adherence to HIV/AIDS treatment and prevention. However, the LA-ARV formulations currently in clinical trials cannot be removed after administration even if adverse events occur. Here we show an ultra-LA removable system that delivers drug for up to 9 months and can be safely removed to stop drug delivery. We use two pre-clinical models for HIV transmission and treatment, non-human primates (NHP) and humanized BLT (bone marrow/liver/thymus) mice and show a single dose of subcutaneously administered ultra-LA dolutegravir effectively delivers the drug in both models and show suppression of viremia and protection from multiple high-dose vaginal HIV challenges in BLT mice. This approach represents a potentially effective strategy for the ultra-LA drug delivery with multiple possible therapeutic applications. PMID- 30297892 TI - Towards poliovirus eradication.

AB - Retinal gene therapy is increasingly recognized as a novel molecular intervention that has huge potential in treating common causes of blindness, the majority of which have a genetic aetiology1-5. Choroideremia is a chronic X-linked retinal degeneration that was first described in 18726. It leads to progressive blindness due to deficiency of Rab-escort protein 1 (REP1). We designed an adeno-associated viral vector to express REP1 and assessed it in a gene therapy clinical trial by subretinal injection in 14 patients with choroideremia. The primary endpoint was vision change in treated eyes 2 years after surgery compared to unoperated fellow eyes. Despite complications in two patients, visual acuity improved in the 14 treated eyes over controls (median 4.5 letter gain, versus 1.5 letter loss, P = 0.04), with 6 treated eyes gaining more than one line of vision (>5 letters). The results suggest that retinal gene therapy can sustain and improve visual acuity in a cohort of predominantly late-stage choroideremia patients in whom rapid visual acuity loss would ordinarily be predicted.

AB - Impaired immunity in patients with late-stage cancer is not limited to antitumor responses, as demonstrated by poor vaccination protection and high susceptibility to infection1-3. This has been largely attributed to chemotherapy-induced impairment of innate immunity, such as neutropenia2, whereas systemic effects of tumors on hematopoiesis and adoptive immunity remain incompletely understood. Here we observed anemia associated with severe deficiency of CD8+ T cell responses against pathogens in treatment-naive mice bearing large tumors. Specifically, we identify CD45+ erythroid progenitor cells (CD71+TER119+; EPCs) as robust immunosuppressors. CD45+ EPCs, induced by tumor growth-associated extramedullary hematopoiesis, accumulate in the spleen to become a major population, outnumbering regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs). The CD45+ EPC transcriptome closely resembles that of MDSCs, and, like MDSCs, reactive oxygen species production is a major mechanism underlying CD45+ EPC-mediated immunosuppression. Similarly, an immunosuppressive CD45+ EPC population was detected in patients with cancer who have anemia. These findings identify a major population of immunosuppressive cells that likely contributes to the impaired T cell responses commonly observed in patients with advanced cancer. PMID- 30297903 TI - In utero CRISPR-mediated therapeutic editing of metabolic genes. AB - In utero gene editing has the potential to prenatally treat genetic diseases that result in significant morbidity and mortality before or shortly after birth. We assessed the viral vector-mediated delivery of CRISPR-Cas9 or base editor 3 in utero, seeking therapeutic modification of Pcsk9 or Hpd in wild-type mice or the murine model of hereditary tyrosinemia type 1, respectively. We observed long term postnatal persistence of edited cells in both models, with reduction of plasma PCSK9 and cholesterol levels following in utero Pcsk9 targeting and rescue of the lethal phenotype of hereditary tyrosinemia type 1 following in utero Hpd targeting. The results of this proof-of-concept work demonstrate the possibility of efficiently performing gene editing before birth, pointing to a potential new therapeutic approach for selected congenital genetic disorders. PMID- 30297904 TI - Treatment of a metabolic liver disease by in vivo genome base editing in adult mice. AB - CRISPR-Cas-based genome editing holds great promise for targeting genetic disorders, including inborn errors of hepatocyte metabolism. Precise correction of disease-causing mutations in adult tissues in vivo, however, is challenging. It requires repair of Cas9-induced double-stranded DNA (dsDNA) breaks by homology directed mechanisms, which are highly inefficient in nondividing cells. Here we corrected the disease phenotype of adult phenylalanine hydroxylase (Pah)enu2 mice, a model for the human autosomal recessive liver disease phenylketonuria (PKU)1, using recently developed CRISPR-Cas-associated base editors2-4. These systems enable conversion of C?G to T?A base pairs and vice versa, independent of dsDNA break formation and homology-directed repair (HDR). We engineered and validated an intein-split base editor, which allows splitting of the fusion protein into two parts, thereby circumventing the limited cargo capacity of adeno associated virus (AAV) vectors. Intravenous injection of AAV-base editor systems resulted in Pahenu2 gene correction rates that restored physiological blood phenylalanine (L-Phe) levels below 120 umol/l [5]. We observed mRNA correction rates up to 63%, restoration of phenylalanine hydroxylase (PAH) enzyme activity, and reversion of the light fur phenotype in Pahenu2 mice. Our findings suggest that targeting genetic diseases in vivo using AAV-mediated delivery of base editing agents is feasible, demonstrating potential for therapeutic application. PMID- 30297905 TI - Offering a choice between NIPT and invasive PND in prenatal genetic counseling: the impact of clinician characteristics on patients' test uptake. AB - Testing options for pregnant women at increased risk of common aneuploidies are non-invasive prenatal testing (NIPT) and invasive prenatal diagnosis (PND). Clinicians are challenged to comprehensively discuss the complex information in a patient-centered and non-directive manner, to allow for patients' informed decision-making. This study explored the information-centeredness, patient centeredness, and level of non-directivity of different clinicians and examined group differences between their patients. First, semi-structured interviews with four senior obstetricians and one senior nurse were held regarding their information provision, their adaptation of a patient-centered attitude, and their practice of non-directivity. Interviews were transcribed verbatim and rated by four independent researchers. Secondly, 181 pregnant women were included in the study, of whom 82% opted for NIPT and 18% chose PND. Between clinicians, we assessed the distribution of choice ratios, patients' impression of clinicians' test preferences, and patients' knowledge scores. The results indicate that clinicians do not differ in their information-centeredness, but do differ in their patient-centeredness and their level of non-directivity. Significant differences in patients' NIPT/PND ratios were observed between clinicians, with the largest difference being 35 vs. 4% opting for invasive PND. Between 9 and 22% of the patients had an impression of their clinician's preference and chose in accordance with this preference. Patients' overall knowledge scores did not differ across clinicians. In conclusion, the differences in NIPT/PND ratios between clinicians indicate that clinicians' differing counseling approaches affect the choices their patients make. The interviews indicate a possible framing effect which may unintentionally steer the decision-making process. PMID- 30297906 TI - The comprehensive mutational and phenotypic spectrum of TUBB8 in female infertility. AB - Human oocyte maturation is a precondition for fertilization and ensuing embryonic development. Previously, we identified TUBB8 variants as a genetic determinant of human oocyte maturation arrest and showed that these variants cause variable and mixed phenotypes in oocyte maturation and early embryo development. We also estimated that rare inherited or de novo variants in the TUBB8 gene accounted for 30% of individuals in a small cohort of patients affected by oocyte maturation arrest. In the present study, we recruited a further 87 patients from unrelated families diagnosed with oocyte maturation or early embryonic arrest and identified 30 patients carrying TUBB8 variants. The corresponding phenotypes not only include oocyte maturation arrest, failure of fertilization, and early embryonic arrest, but also extend to the new phenotype of failure of embryo implantation. These observations provide the most detailed mutational and phenotypic spectrum of TUBB8, further extend the spectrum of variants and dysfunctional oocyte and embryo phenotypes caused by TUBB8 variants, and confirm previous findings for a critical role of TUBB8 during oocyte maturation and early embryonic development. Thus, TUBB8 mutation screening might not only be a genetic diagnostic marker for patients with oocyte maturation arrest, but might also have clinical implications for evaluating the competence of patients' functional oocytes with first polar body (PB1).

PMID- 30297908 TI - Structure-guided combination therapy to potently improve the function of mutant CFTRs. AB - Available corrector drugs are unable to effectively rescue the folding defects of CFTR-DeltaF508 (or CFTR-F508del ), the most common disease-causing mutation of the cystic fibrosis transmembrane conductance regulator, a plasma membrane (PM) anion channel, and thus to substantially ameliorate clinical phenotypes of cystic fibrosis (CF). To overcome the corrector efficacy ceiling, here we show that compounds targeting distinct structural defects of CFTR can synergistically rescue mutant expression and function at the PM. High-throughput cell-based screens and mechanistic analysis identified three small-molecule series that target defects at nucleotide-binding domain (NBD1), NBD2 and their membrane spanning domain (MSD) interfaces. Although individually these compounds marginally improve DeltaF508-CFTR folding efficiency, function and stability, their combinations lead to ~50-100% of wild-type-level correction in immortalized and primary human airway epithelia and in mouse nasal epithelia. Likewise, corrector combinations were effective against rare missense mutations in various CFTR domains, probably acting via structural allostery, suggesting a mechanistic framework for their broad application. PMID- 30297909 TI - Neoadjuvant immune checkpoint blockade in high-risk resectable melanoma. AB - Preclinical studies suggest that treatment with neoadjuvant immune checkpoint blockade is associated with enhanced survival and antigen-specific T cell responses compared with adjuvant treatment1; however, optimal regimens have not been defined. Here we report results from a randomized phase 2 study of neoadjuvant nivolumab versus combined ipilimumab with nivolumab in 23 patients with high-risk resectable melanoma ( NCT02519322 ). RECIST overall response rates (ORR), pathologic complete response rates (pCR), treatment-related adverse events (trAEs) and immune correlates of response were assessed. Treatment with combined ipilimumab and nivolumab yielded high response rates (RECIST ORR 73%, pCR 45%) but substantial toxicity (73% grade 3 trAEs), whereas treatment with nivolumab monotherapy yielded modest responses (ORR 25%, pCR 25%) and low toxicity (8% grade 3 trAEs). Immune correlates of response were identified, demonstrating higher lymphoid infiltrates in responders to both therapies and a more clonal and diverse T cell infiltrate in responders to nivolumab monotherapy. These results describe the feasibility of neoadjuvant immune checkpoint blockade in melanoma and emphasize the need for additional studies to optimize treatment regimens and to validate putative biomarkers.

Numerous studies report the potential of pharmacological approaches (for example, growth factors, immunosuppressants) to accelerate and enhance nerve regeneration in rodent models3-10. Unfortunately, few have had a positive impact in clinical practice. Direct intraoperative electrical stimulation of injured nerve tissue proximal to the site of repair has been demonstrated to enhance and accelerate functional recovery11,12, suggesting a novel nonpharmacological, bioelectric form of therapy that could complement existing surgical approaches. A significant limitation of this technique is that existing protocols are constrained to intraoperative use and limited therapeutic benefits13. Herein we introduce (i) a platform for wireless, programmable electrical peripheral nerve stimulation, built with a collection of circuit elements and substrates that are entirely bioresorbable and biocompatible, and (ii) the first reported demonstration of enhanced neuroregeneration and functional recovery in rodent models as a result of multiple episodes of electrical stimulation of injured nervous tissue. PMID- 30297911 TI - Neoadjuvant versus adjuvant ipilimumab plus nivolumab in macroscopic stage III melanoma. AB - Adjuvant ipilimumab (anti-CTLA-4) and nivolumab (anti-PD-1) both improve relapse free survival of stage III melanoma patients1,2. In stage IV disease, the combination of ipilimumab + nivolumab is superior to ipilimumab alone and also appears to be more effective than nivolumab monotherapy3. Preclinical work suggests that neoadjuvant application of checkpoint inhibitors may be superior to adjuvant therapy4. To address this question and to test feasibility, 20 patients with palpable stage III melanoma were 1:1 randomized to receive ipilimumab 3 mg kg-1 and nivolumab 1 mg kg-1, as either four courses after surgery (adjuvant arm) or two courses before surgery and two courses postsurgery (neoadjuvant arm). Neoadjuvant therapy was feasible, with all patients undergoing surgery at the preplanned time point. However in both arms, 9/10 patients experienced one or more grade 3/4 adverse events. Pathological responses were achieved in 7/9 (78%) patients treated in the neoadjuvant arm. None of these patients have relapsed so far (median follow-up, 25.6 months). We found that neoadjuvant ipilimumab + nivolumab expand more tumor-resident T cell clones than adjuvant application. While neoadjuvant therapy appears promising, with the current regimen it induced high toxicity rates; therefore, it needs further investigation to preserve efficacy but reduce toxicity.

AB - Acute intermittent porphyria (AIP) results from haploinsufficiency of porphobilinogen deaminase (PBGD), the third enzyme in the heme biosynthesis pathway. Patients with AIP have neurovisceral attacks associated with increased hepatic heme demand. Phenobarbital-challenged mice with AIP recapitulate the biochemical and clinical characteristics of patients with AIP, including hepatic overproduction of the potentially neurotoxic porphyrin precursors. Here we show that intravenous administration of human PBGD (hPBGD) mRNA (encoded by the gene HMBS) encapsulated in lipid nanoparticles induces dose-dependent protein expression in mouse hepatocytes, rapidly normalizing urine porphyrin precursor excretion in ongoing attacks. Furthermore, hPBGD mRNA protected against mitochondrial dysfunction, hypertension, pain and motor impairment. Repeat dosing in AIP mice showed sustained efficacy and therapeutic improvement without evidence of hepatotoxicity. Finally, multiple administrations to nonhuman primates confirmed safety and translatability. These data provide proof-of concept for systemic hPBGD mRNA as a potential therapy for AIP. PMID- 30297913 TI - Transcriptomic responses of Serratia liquefaciens cells grown under simulated Martian conditions of low temperature, low pressure, and CO2-enriched anoxic atmosphere. AB - Results from previous experiments indicated that the Gram-negative alpha proteobacterium Serratia liquefaciens strain ATCC 27592 was capable of growth under low temperature (0 degrees C), low pressure (0.7 kPa), and anoxic, CO2 dominated atmosphere-conditions intended to simulate the near-subsurface environment of Mars. To probe the response of its transcriptome to this extreme environment, S. liquefaciens ATCC 27592 was cultivated under 4 different environmental simulations: 0 degrees C, 0.7 kPa, CO2 atmosphere (Condition A); 0 degrees C, ~101.3 kPa, CO2 atmosphere (Condition B); 0 degrees C, ~101.3 kPa, ambient N2/O2 atmosphere (Condition C); and 30 degrees C, ~101.3 kPa, N2/O2 atmosphere (Condition D; ambient laboratory conditions). RNA-seq was performed on ribosomal RNA-depleted total RNA isolated from triplicate cultures grown under Conditions A-D and the datasets generated were subjected to transcriptome analyses. The data from Conditions A, B, or C were compared to laboratory Condition D. Significantly differentially expressed transcripts were identified belonging to a number of KEGG pathway categories. Up-regulated genes under all Conditions A, B, and C included those encoding transporters (ABC and PTS transporters); genes involved in translation (ribosomes and their biogenesis, biosynthesis of both tRNAs and aminoacyl-tRNAs); DNA repair and recombination; and non-coding RNAs. Genes down-regulated under all Conditions A, B, and C included: transporters (mostly ABC transporters); flagellar and motility proteins; genes involved in phenylalanine metabolism; transcription factors; and two-component systems. The results are discussed in the context of Mars astrobiology and planetary protection. PMID- 30297914 TI - Sexual Arousal Patterns of Identical Twins with Discordant Sexual Orientations. AB - Genetically identical twins can differ in their self-reported sexual orientations. However, whether the twins' subjective reports reflect valid differences in their sexual orientations is unknown. Measures of sexual orientation, which are free of the limitations of self-report, include genital arousal and pupil dilation while viewing sexual stimuli depicting men or women. We examined these responses in 6 male twin pairs and 9 female twin pairs who reported discordant sexual orientations. Across measures, heterosexual male twins responded more strongly to women than to men. Their homosexual co-twins showed an opposite pattern. Heterosexual female twins responded equally to both sexes, whereas their homosexual co-twins responded somewhat more to women than men. These differences within pairs were similar to differences between unrelated heterosexual and homosexual males and females. Our study provides physiological evidence confirming twins' discordant sexual orientations, thereby supporting the importance of the non-shared environment for the development of sexual orientation and sexual arousal. PMID- 30297916 TI - On-Chip Curing by Microwave for Long Term Usage of Electronic Devices in Harsh Environments. AB - Microwave-induced thermal curing is demonstrated to improve the reliability and to prolong the lifetime of chips containing nanoscale electron devices. A film containing graphite powder with high microwave absorbing efficiency was fabricated at low cost. The film is flexible, bendable, foldable, and attachable to a chip. A commercial off-the-shelf chip and a representative 3-dimensional (3D) metal-oxide-semiconductor field-effect transistor (MOSFET), known as FinFET, were utilized to verify the curing behaviors of the microwave-induced heat treatment. The heat effectively cured not only total ionizing dose (TID) damage from the external environment, but also internal electrical stress such as hot carrier injection (HCI), which are representative sources of damages in MOSFET insulators. Then, the characteristics of the pre- and post-curing electron devices are investigated using electrical measurements and numerical simulations. PMID- 30297915 TI - Multiple intrasyntenic rearrangements and rapid speciation in voles. AB - Remarkably stable genomic chromosome elements (evolutionary conserved segments or syntenies) are the basis of large-scale chromosome architecture in vertebrate species. However, these syntenic elements harbour evolutionary important changes through intrachromosomal rearrangements such as inversions and centromere repositioning. Here, using FISH with a set of 20 region-specific probes on a wide array of 28 species, we analyzed evolution of three conserved syntenic regions of the Arvicolinae ancestral karyotype. Inside these syntenies we uncovered multiple, previously cryptic intrachromosomal rearrangements. Although in each of the three conserved blocks we found inversions and centromere repositions, the blocks experienced different types of rearrangements. In two syntenies centromere repositioning predominated, while in the third region, paracentric inversions were more frequent, whereas pericentric inversions were not detected. We found that some of the intrachromosomal rearrangements, mainly paracentric inversions, were synapomorphic for whole arvicoline genera or tribes: genera Alexandromys and Microtus, tribes Ellobini and Myodini. We hypothesize that intrachromosomal rearrangements within conserved syntenic blocks are a major evolutionary force modulating genome architecture in species-rich and rapidly-evolving rodent taxa. Inversions and centromere repositioning may impact speciation and provide a potential link between genome evolution, speciation, and biogeography. PMID- 30297917 TI - DNA fingerprinting at farm level maps rice biodiversity across Bangladesh and reveals regional varietal preferences. AB - The development, dissemination, and adoption of improved rice varieties are imperative for global food and nutritional security. Knowledge of the crop's distribution across agro-ecologies is important for impact assessment studies, varietal replacement strategies, and the development and implementation of agricultural policies. Bangladesh is the world's 4th largest rice producer. Though traditional varieties (TVs) are abundant and valued throughout Bangladesh, population growth and vulnerability to climate change, necessitate efficient deployment of high-yielding stress-tolerant modern varieties (MVs). To aid agricultural policy and strategy this study aimed to accurately assess the distribution of MVs and TVs across Bangladesh during the rainfed rice-growing season. Information derived from a survey of rice production areas were compared and combined with DNA fingerprinting information from the same locations. Biodiversity of Bangladesh rice remained high. While TVs and first generation MVs of Bangladeshi and Indian origin were still commonly grown, recently released stress-tolerant MVs were adopted in large proportions in several districts. Although farmers successfully distinguished TVs from MVs grown in their fields, a considerable lack of authenticity among MVs was observed, pinpointing shortcomings in the seed supply chain. This study identifies focal points for extension work and validates DNA fingerprinting as reliable method for impact assessment studies. PMID- 30297918 TI - Policy options for reducing antibiotics and antibiotic-resistant genes in the environment. AB - Responses to the threat posed by antimicrobial resistance have been inadequate. Most attention has focused on the emergence of resistant organisms in human medicine and in agriculture. Much less attention has been given to antibiotic contamination of the environment. To assist health advocates to engage with this issue, we review the evidence on the role of agriculture, aquaculture, domestic waste and pharmaceutical manufacturing in the spread of antibiotic resistance, concluding that all of these activities pose a potentially serious threat. We then examine ways that this threat might be mitigated by specific measures, such as improved wastewater treatment processes, reduction of manufacturing emissions, consideration of environmental impacts in procurement and drug approval decisions, and better manure management. We conclude by placing this problem within the growing literature on commercial determinants of health, stressing the need for effective legislation and regulation developed independent of vested interests.

PMID- 30297919 TI - Human blastocysts of normal and abnormal karyotypes display distinct transcriptome profiles. AB - Unveiling the transcriptome of human blastocysts can provide a wealth of important information regarding early embryonic ontology. Comparing the mRNA production of embryos with normal and abnormal karyotypes allows for a deeper understanding of the protein pathways leading to viability and aberrant fetal development. In addition, identifying transcripts specific for normal or abnormal chromosome copy number could aid in the search for secreted substances that could be used to non-invasively identify embryos best suited for IVF embryo transfer. Using RNA-seq, we characterized the transcriptome of 71 normally developing human blastocysts that were karyotypically normal vs. trisomic or monosomic. Every monosomy and trisomy of the autosomal and sex chromosomes were evaluated, mostly in duplicate. We first mapped the transcriptome of three normal embryos and found that a common core of more than 3,000 genes is expressed in all embryos. These genes represent pathways related to actively dividing cells, such as ribosome biogenesis and function, spliceosome, oxidative phosphorylation, cell cycle and metabolic pathways. We then compared transcriptome profiles of aneuploid embryos to those of normal embryos. We observed that non-viable embryos had a large number of dysregulated genes, some showing a hundred-fold difference in expression. On the contrary, sex chromosome abnormalities, XO and XXX displayed transcriptomes more closely mimicking those embryos with 23 normal chromosome pairs. Intriguingly, we identified a set of commonly deregulated genes in the majority of both trisomies and monosomies. This is the first paper demonstrating a comprehensive transcriptome delineation of karyotypic abnormalities found in the human pre-implantation embryo. We believe that this information will contribute to the development of new pre-implantation genetic screening methods as well as a better understanding of the underlying developmental abnormalities of abnormal embryos, fetuses and children.

PMID- 30297964 TI - Guide Swap enables genome-scale pooled CRISPR-Cas9 screening in human primary cells. AB - CRISPR-Cas9 screening allows genome-wide interrogation of gene function. Currently, to achieve the high and uniform Cas9 expression desirable for screening, one needs to engineer stable and clonal Cas9-expressing cells-an approach that is not applicable in human primary cells. Guide Swap permits genome scale pooled CRISPR-Cas9 screening in human primary cells by exploiting the unexpected finding that editing by lentivirally delivered, targeted guide RNAs (gRNAs) occurs efficiently when Cas9 is introduced in complex with nontargeting gRNA. We validated Guide Swap in depletion and enrichment screens in CD4+ T cells. Next, we implemented Guide Swap in a model of ex vivo hematopoiesis, and identified known and previously unknown regulators of CD34+ hematopoietic stem and progenitor cell (HSPC) expansion. We anticipate that this platform will be broadly applicable to other challenging cell types, and thus will enable discovery in previously inaccessible but biologically relevant human primary cell systems. PMID- 30297963 TI - The Duality of the MAPK Signaling Pathway in the Control of Metabolic Processes and Cellulase Production in Trichoderma reesei. AB - In this study, through global transcriptional analysis by RNA-Sequencing, we identified the main changes in gene expression that occurred in two functional mutants of the MAPK genes tmk1 and tmk2 in Trichoderma reesei during sugarcane bagasse degradation. We found that the proteins encoded by these genes regulated independent processes, sometimes in a cross-talk manner, to modulate gene expression in T. reesei. In the Deltatmk2 strain, growth in sugarcane bagasse modulated the expression of genes involved in carbohydrate metabolism, cell growth and development, and G-protein-coupled receptor-mediated cell signaling. On the other hand, deletion of tmk1 led to decreased expression of the major genes for cellulases and xylanases. Furthermore, TMK1 found to be involved in the regulation of the expression of major facilitator superfamily transporters. Our results revealed that the MAPK signaling pathway in T. reesei regulates many important processes that allow the fungus to recognize, transport, and metabolize different carbon sources during plant cell wall degradation. PMID- 30297967 TI - Genetic dissection of interspecific differences in yeast thermotolerance. AB - Some of the most unique and compelling survival strategies in the natural world are fixed in isolated species1. To date, molecular insight into these ancient adaptations has been limited, as classic experimental genetics has focused on interfertile individuals in populations2. Here we use a new mapping approach, which screens mutants in a sterile interspecific hybrid, to identify eight housekeeping genes that underlie the growth advantage of Saccharomyces cerevisiae over its distant relative Saccharomyces paradoxus at high temperature. Pro thermotolerance alleles at these mapped loci were required for the adaptive trait in S. cerevisiae and sufficient for its partial reconstruction in S. paradoxus. The emerging picture is one in which S. cerevisiae improved the heat resistance of multiple components of the fundamental growth machinery in response to selective pressure. Our study lays the groundwork for the mapping of genotype to phenotype in clades of sister species across Eukarya. PMID- 30297966 TI - Functional architecture of low-frequency variants highlights strength of negative selection across coding and non-coding annotations. AB - Common variant heritability has been widely reported to be concentrated in variants within cell-type-specific non-coding functional annotations, but little is known about low-frequency variant functional architectures. We partitioned the heritability of both low-frequency (0.5%<= minor allele frequency <5%) and common (minor allele frequency >=5%) variants in 40 UK Biobank traits across a broad set of functional annotations. We determined that non-synonymous coding variants explain 17 +/- 1% of low-frequency variant heritability ([Formula: see text]) versus 2.1 +/- 0.2% of common variant heritability ([Formula: see text]). Cell type-specific non-coding annotations that were significantly enriched for [Formula: see text] of corresponding traits were similarly enriched for [Formula: see text] for most traits, but more enriched for brain-related annotations and traits. For example, H3K4me3 marks in brain dorsolateral prefrontal cortex explain 57 +/- 12% of [Formula: see text] versus 12 +/- 2% of [Formula: see text] for neuroticism. Forward simulations confirmed that low-frequency variant enrichment depends on the mean selection coefficient of causal variants in the annotation, and can be used to predict effect size variance of causal rare variants (minor allele frequency <0.5%). PMID- 30297968 TI - Integrative transcriptome analyses of the aging brain implicate altered splicing in Alzheimer's disease susceptibility. AB - Here we use deep sequencing to identify sources of variation in mRNA splicing in the dorsolateral prefrontal cortex (DLPFC) of 450 subjects from two aging cohorts. Hundreds of aberrant pre-mRNA splicing events are reproducibly associated with Alzheimer's disease. We also generate a catalog of splicing quantitative trait loci (sQTL) effects: splicing of 3,006 genes is influenced by genetic variation. We report that altered splicing is the mechanism for the effects of the PICALM, CLU and PTK2B susceptibility alleles. Furthermore, we performed a transcriptome-wide association study and identified 21 genes with significant associations with Alzheimer's disease, many of which are found in known loci, whereas 8 are in novel loci. These results highlight the convergence of old and new genes associated with Alzheimer's disease in autophagy-lysosomal related pathways. Overall, this study of the transcriptome of the aging brain provides evidence that dysregulation of mRNA splicing is a feature of Alzheimer's disease and is, in some cases, genetically driven.

AB - The deformation of elementary fluid volumes by velocity gradients is a key process for scalar mixing, chemical reactions and biological processes in flows. Whilst fluid deformation in unsteady, turbulent flow has gained much attention over the past half century, deformation in steady random flows with complex structure - such as flow through heterogeneous porous media - has received significantly less attention. In contrast to turbulent flow, the steady nature of these flows constrains fluid deformation to be anisotropic with respect to the fluid velocity, with significant implications for e.g. longitudinal and transverse mixing and dispersion. In this study we derive an ab initio coupled continuous time random walk (CTRW) model of fluid deformation in random steady three-dimensional flow that is based upon a streamline coordinate transform which renders the velocity gradient and fluid deformation tensors upper-triangular. We apply this coupled CTRW model to several model flows and find these exhibit a remarkably simple deformation structure in the streamline coordinate frame, facilitating solution of the stochastic deformation tensor components. These results show that the evolution of longitudinal and transverse fluid deformation for chaotic flows is governed by both the Lyapunov exponent and power-law exponent of the velocity PDF at small velocities, whereas algebraic deformation in non-chaotic flows arises from the intermittency of shear events following similar dynamics as that for steady two-dimensional flow. PMID- 30297972 TI - Genotype and Lifetime Burden of Disease in Hypertrophic Cardiomyopathy: Insights from the Sarcomeric Human Cardiomyopathy Registry (SHaRe). AB - Background: A better understanding of the factors that contribute to heterogeneous outcomes and lifetime disease burden in hypertrophic cardiomyopathy (HCM) is critically needed to improve patient management and outcomes. The Sarcomeric Human Cardiomyopathy Registry (SHaRe) was established to provide the scale of data required to address these issues, aggregating longitudinal datasets curated by eight international HCM specialty centers. Methods: Data on 4591 HCM patients (2763 genotyped), followed for a mean of 5.4+/-6.9 years (24,791 patient years; median [interquartile range] 2.9 [0.3-7.9] years) were analyzed regarding cardiac arrest, cardiac transplantation, appropriate implantable cardioverter defibrillator (ICD) therapy, all-cause death, atrial fibrillation, stroke, New York Heart Association Functional Class III/IV symptoms (all comprising the overall composite endpoint), and left ventricular ejection fraction (LVEF)<35%. Outcomes were analyzed individually and as composite endpoints. Results: Median age of diagnosis was 45.8 [30.9-58.1] years and 37% of patients were female. Age of diagnosis and sarcomere mutation status were predictive of outcomes. Patients <40 years old at diagnosis had a 77% [95% confidence interval: 72%, 80%] cumulative incidence of the overall composite outcome by age 60, compared to 32% [29%, 36%] by age 70 for patients diagnosed >60 years. Young HCM patients (20-29 years) had 4-fold higher mortality than the general United States population at a similar age. Patients with pathogenic/likely pathogenic sarcomere mutations had two-fold greater risk for adverse outcomes compared to patients without mutations; sarcomere variants of uncertain significance were associated with intermediate risk. Heart failure and atrial fibrillation were the most prevalent adverse events, although typically not emerging for several years after diagnosis. Ventricular arrhythmias occurred in 32% [23%, 40%] of patients <40 years at diagnosis, but in 1% [1%, 2%] >60 years. Conclusions: The cumulative burden of HCM is substantial and dominated by heart failure and atrial fibrillation occurring many years following diagnosis. Young age of diagnosis and the presence of a sarcomere mutation are powerful predictors of adverse outcomes. These findings highlight the need for close surveillance throughout life, and the need to develop disease-modifying therapies. PMID- 30297969 TI - Fine-mapping type 2 diabetes loci to single-variant resolution using high-density imputation and islet-specific epigenome maps. AB - We expanded GWAS discovery for type 2 diabetes (T2D) by combining data from 898,130 European-descent individuals (9% cases), after imputation to high-density reference panels. With these data, we (i) extend the inventory of T2D-risk variants (243 loci, 135 newly implicated in T2D predisposition, comprising 403 distinct association signals); (ii) enrich discovery of lower-frequency risk alleles (80 index variants with minor allele frequency <5%, 14 with estimated allelic odds ratio >2); (iii) substantially improve fine-mapping of causal variants (at 51 signals, one variant accounted for >80% posterior probability of association (PPA)); (iv) extend fine-mapping through integration of tissue specific epigenomic information (islet regulatory annotations extend the number of variants with PPA >80% to 73); (v) highlight validated therapeutic targets (18 genes with associations attributable to coding variants); and (vi) demonstrate enhanced potential for clinical translation (genome-wide chip heritability explains 18% of T2D risk; individuals in the extremes of a T2D polygenic risk score differ more than ninefold in prevalence).

AB - The formal (4+1)-cyclization between in situ generated achiral carbonyl stabilized ammonium ylides and vinylogous p-quinone methides can be carried out under operationally simple conditions, leading to two different double bond regioisomers depending on the used conditions.

PMID- 30297971 TI - Allele-defined genome of the autopolyploid sugarcane Saccharum spontaneum L. AB - Modern sugarcanes are polyploid interspecific hybrids, combining high sugar content from Saccharum officinarum with hardiness, disease resistance and ratooning of Saccharum spontaneum. Sequencing of a haploid S. spontaneum, AP85 441, facilitated the assembly of 32 pseudo-chromosomes comprising 8 homologous groups of 4 members each, bearing 35,525 genes with alleles defined. The reduction of basic chromosome number from 10 to 8 in S. spontaneum was caused by fissions of 2 ancestral chromosomes followed by translocations to 4 chromosomes. Surprisingly, 80% of nucleotide binding site-encoding genes associated with disease resistance are located in 4 rearranged chromosomes and 51% of those in rearranged regions. Resequencing of 64 S. spontaneum genomes identified balancing selection in rearranged regions, maintaining their diversity. Introgressed S. spontaneum chromosomes in modern sugarcanes are randomly distributed in AP85-441 genome, indicating random recombination among homologs in different S. spontaneum accessions. The allele-defined Saccharum genome offers new knowledge and resources to accelerate sugarcane improvement. PMID- 30297975 TI - Vowel Formant Dispersion Reflects Severity of Apraxia of Speech. AB - Background: Apraxia of Speech (AOS) has been associated with deviations in consonantal voice-onset-time (VOT), but studies of vowel acoustics have yielded conflicting results. However, a speech motor planning disorder that is not bound by phonological categories is expected to affect vowel as well as consonant articulations. Aims: We measured consonant VOTs and vowel formants produced by a large sample of stroke survivors, and assessed to what extent these variables and their dispersion are predictive of AOS presence and severity, based on a scale that uses clinical observations to rate gradient presence of AOS, aphasia, and dysarthria. Methods & Procedures: Picture-description samples were collected from 53 stroke survivors, including unimpaired speakers (12) and speakers with primarily aphasia (19), aphasia with AOS (12), primarily AOS (2), aphasia with dysarthria (2), and aphasia with AOS and dysarthria (6). The first three formants were extracted from vowel tokens bearing main stress in open-class words, as well as VOTs for voiced and voiceless stops. Vowel space was estimated as reflected in the formant centralization ratio. Stepwise Linear Discriminant Analyses were used to predict group membership, and ordinal regression to predict AOS severity, based on the absolute values of these variables, as well as the standard deviations of formants and VOTs within speakers. Outcomes and Results: Presence and severity of AOS were most consistently predicted by the dispersion of F1, F2, and voiced-stop VOT. These phonetic-acoustic measures do not correlate with aphasia severity. Conclusions: These results confirm that the AOS affects articulation across-the-board and does not selectively spare vowel production. PMID- 30297976 TI - Force detection, center of pressure tracking, and energy harvesting from a piezoelectric knee implant. AB - Recent developments in the field of orthopedic materials and procedures have made the total knee replacement (TKR) an option for people who suffer from knee diseases and injuries. One of the ongoing debates in this area involves the correlation of postoperative joint functionality to intraoperative alignment. Due to a lack of in vivo data from the knee joint after surgery, the establishment of a well-quantified alignment method is hindered. In order to obtain information about knee function after the operation, the design of a self-powered instrumented knee implant is proposed in this study. The design consists of a total knee replacement bearing equipped with four piezoelectric transducers distributed in the medial and lateral compartments. The piezoelectric transducers are utilized to measure the total axial force applied on the tibial bearing through the femoral component of the joint, as well as to track the movement in the center of pressure (CoP). In addition, the generated voltage from the piezoelectrics can be harvested and stored to power embedded electronics for further signal conditioning and data transmission purposes. Initially, finite element (FE) analysis is performed on the knee bearing to select the best location of the transducers with regards to sensing the total force and location of the CoP. A series of experimental tests are then performed on a fabricated prototype which aim to investigate the sensing and energy harvesting performance of the device. Piezoelectric force and center of pressure measurements are compared to actual experimental quantities for twelve different relative positions of the femoral component and bearing of the knee implant in order to evaluate the performance of the sensing system. The output voltage of the piezoelectric transducers is measured across a load resistance to determine the optimum extractable power, and then rectified and stored in a capacitor to evaluate the realistic energy harvesting ability of the system. The results show only a small level of error in sensing the force and the location of the CoP. Additionally, a maximum power of 269.1 MUW is achieved with a 175 kOmega optimal resistive load, and a 4.9 V constant voltage is stored in a 3.3 mF capacitor after 3333 loading cycles. The sensing and energy harvesting results present the promising potential of this system to be used as an integrated self-powered instrumented knee implant. PMID- 30297977 TI - Health Care Resource Utilization and Costs among Adult Patients with Advanced Soft Tissue Sarcoma: A Retrospective Medical Record Review in the United Kingdom, Spain, Germany, and France. AB - Objective: To describe health care resource utilization and costs for patients with advanced soft tissue sarcoma (STS) in the United Kingdom (UK), Spain, Germany, and France. Methods: Physicians abstracted data for adult patients with a diagnosis of advanced STS (other than Kaposi's sarcoma or gastrointestinal stromal tumor) who received >=1 lines of systemic therapy. Health care resource utilization related to advanced STS treatment was recorded; associated costs were estimated by applying unit costs. Results: A total of 130 physicians provided data for 807 patients (UK: 199; Spain: 203; Germany: 204; and France: 201). The site of care during active treatment varied based on differences in the health care systems of these four countries. Total mean per-patient health care cost in the UK was L19,457; in Spain, ?26,814; in Germany, ?20,468; and in France, ?24,368. Advanced STS-related systemic treatment costs were driven primarily by drug acquisition and administration costs. Treatment-related costs increased during later lines of therapy for all countries except France, where they decreased after first-line therapy. Pain control and antiemetics were the most common supportive care medications. Conclusions: This study provides real-world data on resource utilization and estimated costs in advanced STS and could inform policymakers about treatment burden.

PMID- 30297980 TI - Cognitive Rehabilitation of Adaptive Behavior in Children with Neurodevelopmental Disorders: A Meta-Analysis. AB - Objectives: Negative behavioral problems often occur following the onset of neurodevelopmental disorders and have an overall impact on the affected children, specifically in terms of their social developmental level. In children, social development behavior has been shown to spontaneously mature over time with the cognitive therapy intervention effects. This study performed a meta-analysis to provide a statistical synopsis of the available evidence of social development behavioral changes following cognitive therapy in children with neurodevelopmental disorders. Methods: Data was collected from two online search engines, including EBSCOhost and PubMed, from January 1, 2006, to August 31, 2016, using the terms "cognition," "cognitive function," and "disease including neurodevelopmental disorder with DSM-5." Two assessors searched the literature using independent inclusion criteria and evaluated the quality of results using the Jadad score. Six articles were chosen using the Comprehensive Meta-Analysis program (version 2.0). Results: Six articles reporting randomized controlled trial studies were included. The effective scores for improving adaptive behavior following cognitive therapy in children with neurodevelopmental disorder were 0.64. The effective score of adaptive behavior was significant in this study (p < 0.05). The results showed no significant statistical heterogeneity and publication bias. Conclusions: The findings of the meta-analysis suggest that cognitive interventions are effective at improving adaptive behavior associated with neurodevelopmental disorders.

AB - We conducted a knowledge, attitude, and practice (KAP) survey of fragile X associated disorders (FXD) in Serbia in order to obtain baseline quantitative and qualitative KAP data on fragile X mental retardation 1 gene (FMR1) pre- and full mutations (PM, FM). The survey's 16-item questionnaire included a knowledge component (12/16), such as self-assessment knowledge (SAK) and factual knowledge (FK, 2/5 questions for PM, FXTAS and FXPOI). Education-directed attitudes in the FXD field and FMR1 DNA testing practices had 4/16 items, including brief case vignettes of FXTAS and FXPOI, respectively. The study's cohort consisted of primary care physicians (referred to as "physicians" in the rest of the text) throughout Serbia (n = 284, aged 26-64 years, 176/284, 62.2% in Belgrade, Serbia) and senior medical students (n = 245, aged 23-30 years; 33.5% males) at the Belgrade School of Medicine. Strikingly, half of the survey respondents indicated "not having any" knowledge for the fragile X gene premutation and FXD. Physicians were more likely to indicate "not having any" knowledge than students (41.2% of physicians vs. 13.1% of students, P < 0.05). Roughly half of the students had "minimal knowledge" (53.5 vs. 30.5% of physicians, P < 0.05). Low FK was common in the cohort, as few physicians had "all correct answers" (7.5 vs. 3.7% of students, P < 0.05; 16.5 vs. 9.5% of students for the 2/5 premutation-related questions). Statistical analyses identified physicians' practice setting and length of clinical experience as predictors of the lack of FK on questions related to FXD. Physicians were more likely than students to indicate "strongly agreed" to expand their knowledge of the gene premutation and FXD (90.9 vs. 66.7% of students, P < 0.01). However, students more frequently indicated that they are willing to recommend DNA testing in their future practices than physicians (93.5 vs. 64.8% of physicians, P < 0.001). In conclusion, there is a major gap in knowledge regarding fragile X gene PM and FXD among the study's participants in Serbia. The study's informative-educational survey serves as an initial step in the process of enhancing the KAP of medical professionals with regards to the fragile X gene premutation and FXD. PMID- 30297981 TI - Cortical Network Synchrony Under Applied Electrical Field in vitro. AB - Synchronous network activity plays a crucial role in complex brain functions. Stimulating the nervous system with applied electric field (EF) is a common tool for probing network responses. We used a gold wire-embedded silk protein film based interface culture to investigate the effects of applied EFs on random cortical networks of in vitro cultures. Two-week-old cultures were exposed to EF of 27 mV/mm for <1 h and monitored by time-lapse calcium imaging. Network activity was represented by calcium signal time series mapped to source neurons and analyzed by using a community detection algorithm. Cortical cultures exhibited large scale, synchronized oscillations under alternating EF of changing frequencies. Field polarity and frequency change were both found to be necessary for network synchrony, as monophasic pulses of similar frequency changes or EF of a constant frequency failed to induce correlated activities of neurons. Group specific oscillatory patterns were entrained by network-level synchronous oscillations when the alternating EF frequency was increased from 0.2 Hz to 200 kHz. Binary responses of either activity increase or decrease contributed to the opposite phase patterns of different sub-populations. Conversely, when the EF frequency decreased over the same range span, more complex behavior emerged showing group-specific amplitude and phase patterns. These findings formed the basis of a hypothesized network control mechanism for temporal coordination of distributed neuronal activity, involving coordinated stimulation by alternating polarity, and time delay by change of frequency. These novel EF effects on random neural networks have important implications for brain functional studies and neuromodulation applications. PMID- 30297983 TI - Loss of the Cochlear Amplifier Prestin Reduces Temporal Processing Efficacy in the Central Auditory System. AB - Active mechanical amplification of sound occurs in cochlear outer hair cells (OHCs) that change their length with oscillations of their membrane potential. Such length changes are the proposed cellular source of the cochlear amplifier, and prestin is the motor protein responsible for OHC electromotility. Previous findings have shown that mice lacking prestin displayed a loss of OHC electromotility, subsequent loss of distortion-product otoacoustic emissions, and a 40-60 dB increase in hearing thresholds. In this study we were interested in studying the functional consequences of the complete loss of cochlear amplification on neural coding of frequency selectivity, tuning, and temporal processing in the auditory midbrain. We recorded near-field auditory evoked potentials and multi-unit activity from the inferior colliculus (IC) of prestin ( /-) null and prestin (+/+) wild-type control mice and determined frequency response areas (FRAs), tuning sharpness, and gap detection to tone bursts and silent gaps embedded in broadband noise. We were interested in determining if the moderate to severe sensorineural hearing loss associated with the loss of motor protein prestin would also impair auditory midbrain temporal-processing measures, or if compensatory mechanisms within the brainstem could compensate for the loss of prestin. In prestin knockout mice we observed that there are severe impairments in midbrain tuning, thresholds, excitatory drive, and gap detection suggesting that brainstem and midbrain processing could not overcome the auditory processing deficits afforded by the loss of OHC electromotility mediated by the prestin protein. PMID- 30297984 TI - Effective Knockdown of Gene Expression in Primary Microglia With siRNA and Magnetic Nanoparticles Without Cell Death or Inflammation. AB - Microglia, the resident immune cells of the brain, have multiple functions in physiological and pathological conditions, including Alzheimer's disease (AD). The use of primary microglial cell cultures has proved to be a valuable tool to study microglial biology under various conditions. However, more advanced transfection methodologies for primary cultured microglia are still needed, as current methodologies provide low transfection efficiency and induce cell death and/or inflammatory activation of the microglia. Here, we describe an easy, and effective method based on the Glial-Mag method (OZ Biosciences) using magnetic nanoparticles and a magnet to successfully transfect primary microglia cells with different small interfering RNAs (siRNAs). This method does not require specialist facilities or specific training and does not induce cell toxicity or inflammatory activation. We demonstrate that this protocol successfully decreases the expression of two key genes associated with AD, the triggering receptor expressed in myeloid cells 2 (TREM2) and CD33, in primary microglia cell cultures. PMID- 30297985 TI - Innovative Optogenetic Strategies for Vision Restoration. AB - The advent of optogenetics has ushered in a new era in neuroscience where spatiotemporal control of neurons is possible through light application. These tools used to study neural circuits can also be used therapeutically to restore vision. In order to recapitulate the broad spectral and light sensitivities along with high temporal sensitivity found in human vision, researchers have identified and developed new optogenetic tools. There are two major kinds of optogenetic effectors employed in vision restoration: ion channels and G-protein coupled receptors (GPCRs). Ion channel based optogenetic therapies require high intensity light that can be unsafe at lower wavelengths, so work has been done to expand and red-shift the excitation spectra of these channels. Light activatable GPCRs are much more sensitive to light than their ion channel counterparts but are slower kinetically in terms of both activation and inactivation. This review article examines the latest optogenetic ion channel and GPCR candidates for vision restoration based on light and temporal sensitivity. PMID- 30297987 TI - Comparing Mouse and Rat Hippocampal Place Cell Activities and Firing Sequences in the Same Environments. AB - Hippocampal place cells are key to spatial representation and spatial memory processing. They fire at specific locations in a space (place fields) and fire in precise patterns during theta sequences and during ripple-associated replay events. These phenomena have been extensively studied in rats, but to a less extent in mice. The availability of versatile genetic manipulations gives mice an advantage for place cell studies. However, it is unknown how place fields and place cell sequences in the same environment differ between mice and rats. Here, we provide a quantitative comparison in place field properties, as well as theta sequences and replays, between rats and mice as they ran on the same novel track and as they rested afterwards. We found that place cells in mice display less spatial specificity with more but smaller place fields. Theta oscillations, theta phase precession and aspects of theta sequences in mice are similar as those in rats. The ripple-associated replay, however, is relatively rare during stopping on the novel track in mice. The replay is present during resting after the track running, but is weaker in mice than the replay in rats. Our results suggest that place cells in mice and rats are qualitatively similar, but with substantial quantitative differences. PMID- 30297986 TI - The Role of KLF4 in Alzheimer's Disease. AB - Kruppel-like factor 4 (KLF4), a member of the family of zinc-finger transcription factors, is widely expressed in range of tissues that play multiple functions. Emerging evidence suggest KLF4's critical regulatory effect on the neurophysiological and neuropathological processes of Alzheimer's disease (AD), indicating that KLF4 might be a potential therapeutic target of neurodegenerative diseases. In this review, we will summarize relevant studies and illuminate the regulatory role of KLF4 in the neuroinflammation, neuronal apoptosis, axon regeneration and iron accumulation to clarify KLF4's status in the pathogenesis of AD. PMID- 30297989 TI - Sex Differences in Rhesus Monkeys' Digit Ratio (2D:4D Ratio) and Its Association With Maternal Social Dominance Rank. AB - Prenatal androgen exposure (PAE) plays a pivotal role in masculinizing the developing body and brain, and extreme exposure may contribute to autism, anxiety disorder and schizophrenia. One commonly used biomarker for PAE is the pointer-to ring-finger digit length (2D:4D) ratio. Although this biomarker is widely used in human studies, relatively few studies have investigated 2D:4D ratio in nonhuman primates, particularly rhesus macaques (Macaca mulatta), one of the most commonly used animals in biomedical research. Thus far, data suggest that sexual dimorphism in 2D:4D ratio may be in the opposite direction in some monkey species, when compared to the pattern exhibited by humans and great apes. Using a large sample size, we investigated whether rhesus monkeys' 2D:4D ratio shows the same sex-differentiated pattern present in other Old World monkey species. We also investigated whether individual differences in 2D:4D ratio are associated with the social dominance rank of subjects' mothers during pregnancy, and the social dominance rank the subjects attained as adults. Subjects were 335 rhesus monkeys between 3 years and 24 years of age (M = 6.6). Maternal dominance rank during pregnancy and subjects' adult dominance rank were categorized into tertiles (high, middle and low). Results showed that, across both hands, male rhesus monkeys exhibited higher 2D:4D ratio than females, a pattern consistent with other monkey species and a reversal from the pattern typically observed in humans and apes. This sex difference was modulated by maternal dominance rank, with female offspring of high-ranking and middle-ranking mothers exhibiting masculinized 2D:4D ratio, indicating that maternal dominance rank during pregnancy may influence levels of PAE. There was no association between subjects' 2D:4D ratio and the social dominance rank they attained as adults. These findings show a consistent sex difference in Old World monkeys' 2D:4D ratio that diverges from the pattern observed in apes and humans, and suggest maternal social dominance rank modulates PAE in rhesus monkeys. PMID- 30297988 TI - The Immediate Effect of Therapeutic Touch and Deep Touch Pressure on Range of Motion, Interoceptive Accuracy and Heart Rate Variability: A Randomized Controlled Trial With Moderation Analysis. AB - Background: There is paucity in the literature regarding the role of the interoceptive pathway through the insular cortex (IC), as well as heart rate variability (HRV) in relation to Osteopathic Manipulative Therapy (OMT) and deep touch. Aims: The present study investigated whether both OMT treatment and deep touch (a newly hypothesized treatment option) was effective at altering the interoceptive pathway and HRV, whilst OMT was only expected to be effective for increasing Range of Motion (ROM). Methods: Thirty-five healthy volunteers were randomly allocated into three conditions in a repeated measures crossover design; a control (laying supine on a plinth); deep-touch (head cradling); and an osteopathic mobilization therapeutic technique on the temporomandibular joint (TMJ). Interoceptive accuracy (IAc), HRV, as well as range of motion (ROM) for the TMJ area as well as the cervical spine (Csp) right and left measures were taken pre and post each condition setting. Results: Significant condition effects emerged from the deep-touch and mobilization interventions for IAc where increases were identified through planned comparisons. For the HRV measure (RMSSD), a significant effect emerged in the deep-touch condition (increase) but not in the mobilization or control conditions. ROM did not increase for any condition. IAc correlated with post-ROM outcomes in many cases and HRV moderated some of these relations. Conclusion: These results are discussed in the context of clinical practice, where cranial deep-touch maybe an effective treatment and modulator of the parasympathetic nervous systems, as well as the interoceptive system. PMID- 30297990 TI - Mice With Partial Deletion of Y-Heterochromatin Exhibits Stress Vulnerability. AB - The role of Y chromosome in sex determination and male fertility is well established. It is also known that infertile men are prone to psychological disturbances. Earlier studies in the laboratory identified genes expressed in testes that are putatively regulated by Y chromosome in man and mouse. With the availability of a Y-deleted mouse model, that is subfertile, we studied the effect of a partial deletion of Y-chromosomal heterochromatin on mouse behavior when compared to its wild type. The partial Y-deleted mice exhibited anxiety like phenotype under stress when different anxiety (open field test and elevated plus maze, EPM test) and depression related tests (tail suspension and force swim) were performed. The mutant mice also showed reduction in hippocampal neurogenesis and altered expression of neurogenesis markers such as Nestin, Sox2, Gfap, NeuroD1 and Dcx using quantitative real time PCR (qPCR) analysis. The genes with altered expression contained short stretches of homology to Y-derived transcripts only in their Untranslated Regions (UTRs). Our study suggests putative regulation of these genes by the Y chromosome in mouse brain altering stress related behavior. PMID- 30297991 TI - Theta Activity in the Left Dorsal Premotor Cortex During Action Re-Evaluation and Motor Reprogramming. AB - The ability to rapidly adjust our actions to changes in the environment is a key function of human motor control. Previous work implicated the dorsal premotor cortex (dPMC) in the up-dating of action plans based on environmental cues. Here we used electroencephalography (EEG) to identify neural signatures of up-dating cue-action relationships in the dPMC and connected frontoparietal areas. Ten healthy subjects performed a pre-cued alternate choice task. Simple geometric shapes cued button presses with the right or left index finger. The shapes of the pre-cue and go-cue differed in two third of trials. In these incongruent trials, the go-cue prompted a re-evaluation of the pre-cued action plan, slowing response time relative to trials with identical cues. This re-evaluation selectively increased theta band activity without modifying activity in alpha and beta band. Source-based analysis revealed a widespread theta increase in dorsal and mesial frontoparietal areas, including dPMC, supplementary motor area (SMA), primary motor and posterior parietal cortices (PPC). Theta activity scaled positively with response slowing and increased more strongly when the pre-cue was invalid and required subjects to select the alternate response. Together, the results indicate that theta activity in dPMC and connected frontoparietal areas is involved in the re-adjustment of cue-induced action tendencies. PMID- 30297992 TI - Substance-Specific Differences in Human Electroencephalographic Burst Suppression Patterns. AB - Different anesthetic agents induce burst suppression in the electroencephalogram (EEG) at very deep levels of general anesthesia. EEG burst suppression has been identified to be a risk factor for postoperative delirium (POD). EEG based automated detection algorithms are used to detect burst suppression patterns during general anesthesia and a burst suppression ratio (BSR) is calculated. Unfortunately, applied algorithms do not give information as precisely as suggested, often resulting in an underestimation of the patients' burst suppression level. Additional knowledge of substance-specific burst suppression patterns could be of great importance to improve the ability of EEG based monitors to detect burst suppression. In a re-analysis of EEG recordings obtained from a previous study, we analyzed EEG data of 45 patients undergoing elective surgery under general anesthesia. The patients were anesthetized with sevoflurane, isoflurane or propofol (n = 15, for each group). After skin incision, the used agent was titrated to a level when burst suppression occurred. In a visual analysis of the EEG, blinded to the used anesthetic agent, we included the first distinct burst in our analysis. To avoid bias through changing EEG dynamics throughout the burst, we only focused on the first 2 s of the burst. These episodes were analyzed using the power spectral density (PSD) and normalized PSD, the absolute burst amplitude and absolute burst slope, as well as permutation entropy (PeEn). Our results show significant substance-specific differences in the architecture of the burst. Volatile-induced bursts showed higher burst amplitudes and higher burst power. Propofol-induced bursts had significantly higher relative power in the EEG alpha-range. Further, isoflurane induced bursts had the steepest burst slopes. We can present the first systematic comparison of substance-specific burst characteristics during anesthesia. Previous observations, mostly derived from animal studies, pointing out the substance-specific differences in bursting behavior, concur with our findings. Our findings of substance-specific EEG characteristics can provide information to help improve automated burst suppression detection in monitoring devices. More specific detection of burst suppression may be helpful to reduce excessive EEG effects of anesthesia and therefore the incidence of adverse outcomes such as POD. PMID- 30297993 TI - Markov Model-Based Method to Analyse Time-Varying Networks in EEG Task-Related Data. AB - The dynamic nature of functional brain networks is being increasingly recognized in cognitive neuroscience, and methods to analyse such time-varying networks in EEG/MEG data are required. In this work, we propose a pipeline to characterize time-varying networks in single-subject EEG task-related data and further, evaluate its validity on both simulated and experimental datasets. Pre-processing is done to remove channel-wise and trial-wise differences in activity. Functional networks are estimated from short non-overlapping time windows within each "trial," using a sparse-MVAR (Multi-Variate Auto-Regressive) model. Functional "states" are then identified by partitioning the entire space of functional networks into a small number of groups/symbols via k-means clustering.The multi trial sequence of symbols is then described by a Markov Model (MM). We show validity of this pipeline on realistic electrode-level simulated EEG data, by demonstrating its ability to discriminate "trials" from two experimental conditions in a range of scenarios. We then apply it to experimental data from two individuals using a Brain-Computer Interface (BCI) via a P300 oddball task. Using just the Markov Model parameters, we obtain statistically significant discrimination between target and non-target trials. The functional networks characterizing each 'state' were also highly similar between the two individuals. This work marks the first application of the Markov Model framework to infer time varying networks from EEG/MEG data. Due to the pre-processing, results from the pipeline are orthogonal to those from conventional ERP averaging or a typical EEG microstate analysis. The results provide powerful proof-of-concept for a Markov model-based approach to analyzing the data, paving the way for its use to track rapid changes in interaction patterns as a task is being performed. MATLAB code for the entire pipeline has been made available. PMID- 30297995 TI - The Head Turning Modulation System: An Active Multimodal Paradigm for Intrinsically Motivated Exploration of Unknown Environments. AB - Over the last 20 years, a significant part of the research in exploratory robotics partially switches from looking for the most efficient way of exploring an unknown environment to finding what could motivate a robot to autonomously explore it. Moreover, a growing literature focuses not only on the topological description of a space (dimensions, obstacles, usable paths, etc.) but rather on more semantic components, such as multimodal objects present in it. In the search of designing robots that behave autonomously by embedding life-long learning abilities, the inclusion of mechanisms of attention is of importance. Indeed, be it endogenous or exogenous, attention constitutes a form of intrinsic motivation for it can trigger motor command toward specific stimuli, thus leading to an exploration of the space. The Head Turning Modulation model presented in this paper is composed of two modules providing a robot with two different forms of intrinsic motivations leading to triggering head movements toward audiovisual sources appearing in unknown environments. First, the Dynamic Weighting module implements a motivation by the concept of Congruence, a concept defined as an adaptive form of semantic saliency specific for each explored environment. Then, the Multimodal Fusion and Inference module implements a motivation by the reduction of Uncertainty through a self-supervised online learning algorithm that can autonomously determine local consistencies. One of the novelty of the proposed model is to solely rely on semantic inputs (namely audio and visual labels the sources belong to), in opposition to the traditional analysis of the low-level characteristics of the perceived data. Another contribution is found in the way the exploration is exploited to actively learn the relationship between the visual and auditory modalities. Importantly, the robot-endowed with binocular vision, binaural audition and a rotating head-does not have access to prior information about the different environments it will explore. Consequently, it will have to learn in real-time what audiovisual objects are of "importance" in order to rotate its head toward them. Results presented in this paper have been obtained in simulated environments as well as with a real robot in realistic experimental conditions. PMID- 30297994 TI - Causes of Performance Degradation in Non-invasive Electromyographic Pattern Recognition in Upper Limb Prostheses. AB - Surface Electromyography (EMG)-based pattern recognition methods have been investigated over the past years as a means of controlling upper limb prostheses. Despite the very good reported performance of myoelectric controlled prosthetic hands in lab conditions, real-time performance in everyday life conditions is not as robust and reliable, explaining the limited clinical use of pattern recognition control. The main reason behind the instability of myoelectric pattern recognition control is that EMG signals are non-stationary in real-life environments and present a lot of variability over time and across subjects, hence affecting the system's performance. This can be the result of one or many combined changes, such as muscle fatigue, electrode displacement, difference in arm posture, user adaptation on the device over time and inter-subject singularity. In this paper an extensive literature review is performed to present the causes of the drift of EMG signals, ways of detecting them and possible techniques to counteract for their effects in the application of upper limb prostheses. The suggested techniques are organized in a table that can be used to recognize possible problems in the clinical application of EMG-based pattern recognition methods for upper limb prosthesis applications and state-of-the-art methods to deal with such problems. PMID- 30297996 TI - Dopamine Receptor Activation Is Required for GABAergic Spike Timing-Dependent Plasticity in Response to Complex Spike Pairing in the Ventral Tegmental Area. AB - One of the most influential synaptic learning rules explored in the past decades is activity dependent spike-timing-dependent plasticity (STDP). In STDP, synapses are either potentiated or depressed based on the order of pre- and postsynaptic neuronal activation within narrow, milliseconds-long, time intervals. STDP is subject to neuromodulation by dopamine (DA), a potent neurotransmitter that significantly impacts synaptic plasticity and reward-related behavioral learning. Previously, we demonstrated that GABAergic synapses onto ventral tegmental area (VTA) DA neurons are able to express STDP (Kodangattil et al., 2013), however it is still unclear whether DA modulates inhibitory STDP in the VTA. Here, we used whole-cell recordings in rat midbrain slices to investigate whether DA D1-like and/or D2-like receptor (D1R/D2R) activation is required for induction of STDP in response to a complex pattern of spiking. We found that VTA but not Substantia nigra pars compact (SNc) DA neurons exhibit long-term depression (LTDGABA) in response to a combination of positive (pre-post) and negative (post-pre) timing of spiking (a complex STDP protocol). Blockade of either D1Rs or D2Rs prevented the induction of LTDGABA while activation of D1Rs did not affect the plasticity in response to this complex STDP protocol in VTA DA neurons.Our data suggest that this DA-dependent GABAergic STDP is selectively expressed at GABAergic synapses onto VTA DA neurons which could be targeted by drugs of abuse to mediate drug induced modulation of DA signaling within the VTA, as well as in VTA-projection areas, thereby affecting reward-related learning and drug-associated memories. PMID- 30297997 TI - The Combination of Functional and Structural MRI Is a Potential Screening Tool in Alzheimer's Disease. AB - Introduction: This study aimed to survey the discrimination power of parameters from cerebrospinal fluid (CSF) biomarkers, fluorodeoxyglucose uptake on PET (FDG PET), structural magnetic resonance imaging (MRI), and functional MRI in high- and low-risk subjects or in converters and stable subjects of normal and mild cognitive impairment (MCI) statuses. Methods: We used baseline resting-state functional MRI (rfMRI) from the Alzheimer's Disease Neuroimaging Initiative (ADNI) dataset to analyze functional networks and recorded subjects' characteristics and results of the CSF study, FDG-PET, and structural MRI from the ADNI website. All parameters were evaluated based on the between-group difference among normal (NC), MCI, and Alzheimer's disease (AD) groups. The parameters other than CSF results were included to study the difference between high- and low-AD-risk subjects in NC or MCI groups, based on CSF results. On the basis of two-year follow-up conditions, all parameters were compared between stable subjects and converters in NC and MCI. Results: CSF biomarkers, FDG-PET, structural MRI, and functional MRI are all able to differentiate AD from MCI or NC but not between MCI and NC. As compared with low-AD-risk subjects, high-risk subjects present decreased FDG-PET in both MCI and NC groups but structural MRI change only in MCI status and rfMRI alteration only in NC status. As compared with stable subjects, converters have decreased FDG-PET, functional network changes, and structural changes in both MCI and NC groups. Conclusion: The combination of functional and structural MRI is a safer screening tool but with similar power as FDG-PET to reflect CSF change in the AD pathological process and to identify high-risk subjects and converters in NC and MCI. PMID- 30297998 TI - Age Influences Microglial Activation After Cuprizone-Induced Demyelination. AB - Multiple sclerosis (MS) is a chronic inflammatory CNS disease, which causes demyelinated lesions and damages white and gray matter regions. Aging is a significant factor in the progression of MS, and microglia, the immune cells of the CNS tissue, play an important role in all disease stages. During aging, microglia are functionally altered. These age-related changes probably already begin early and might influence the progression of CNS pathologies. The aim of the present study was to investigate whether microglia in the middle-aged CNS already react differently to demyelination. For this purpose, several microglia markers (ionized calcium binding adaptor molecule 1 (Iba-1), P2RY12, F4/80, CD68, major histocompatibility complex II (MHCII), macrophage receptor with collagenous structure (Marco), Translocator protein 18 kD (TSPO), CD206, and CD163) were analyzed in the acute cuprizone demyelination model in young (2-month-old) and middle-aged (10-month-old) mice. In addition, microglial proliferation was quantified using double-labeling with proliferating cell nuclear antigen (PCNA) and bromodeoxyuridine (BrdU), which was injected with the onset of remyelination. To compare age-related microglial changes during de- and remyelination in both gray and white matter, the hilus of the dorsal hippocampal dentate gyrus (DG) and the splenium of the corpus callosum (CC) were analyzed in parallel. Age-related changes in microglia of healthy controls were more pronounced in the analyzed gray matter region (higher levels of F4/80 and Marco as well as lower expression of CD68 in middle-aged mice). During de- and remyelination, a stronger increase of the microglial markers Iba-1, CD68 and TSPO was observed in the splenium of the younger groups. There was a significant reduction of P2RY12 during demyelination, however, this was age- and region-dependent. The induction of the anti-inflammatory markers CD206 and CD163 was stronger in the middle-aged group, but also differed between the two analyzed regions. De- and remyelination led to a significant increase in PCNA+ microglia only in young groups within the white matter region. The number of BrdU+ microglia was not changed during de- or remyelination. These results clearly show that microglia are already altered during middle-age and also react differently to CNS demyelination, however, this is highly region-dependent. PMID- 30297999 TI - Astrocyte Activation and the Calcineurin/NFAT Pathway in Cerebrovascular Disease. AB - Calcineurin (CN) is a Ca2+/calmodulin-dependent protein phosphatase with high abundance in nervous tissue. Though enriched in neurons, CN can become strongly induced in subsets of activated astrocytes under different pathological conditions where it interacts extensively with the nuclear factor of activated T cells (NFATs). Recent work has shown that regions of small vessel damage are associated with the upregulation of a proteolized, highly active form of CN in nearby astrocytes, suggesting a link between the CN/NFAT pathway and chronic cerebrovascular disease. In this Mini Review article, we discuss CN/NFAT signaling properties in the context of vascular disease and use previous cell type-specific intervention studies in Alzheimer's disease and traumatic brain injury models as a framework to understand how astrocytic CN/NFATs may couple vascular pathology to neurodegeneration and cognitive loss. PMID- 30298000 TI - Drynaria fortunei Promoted Angiogenesis Associated With Modified MMP-2/TIMP-2 Balance and Activation of VEGF Ligand/Receptors Expression. AB - Background and Purpose: Drynaria fortunei J. Sm (D. fortunei), known as Gu-Sui Bu, is used in traditional Chinese medicine to treat common injuries, including bone fractures and bruising. The specific functional mechanisms of the angiogenic and endothelial cell migration properties of D. fortunei are currently unclear. Thus, the purpose of this study is to validate the potential angiogenic and cellular migration properties and related mechanisms by D. fortunei both in vivo and in vitro. Experimental Approach: The present study investigates, both in vivo and in vitro, the wound healing effects of D. fortunei as associated with angiogenesis, specifically by the modulation of matrix metalloproteinases (MMPs) and upregulation of vascular endothelial growth factor (VEGF) ligand/receptors. In order to determine the potential angiogenic effects of D. fortunei, in vivo neovascularization of chick chorioallantoic membranes (CAMs) assay, and directed in vivo angiogenesis assay (DIVVA) were performed, while in vitro scratch wound healing, migration, and matrix-induced tube formation assays were performed by using human umbilical vascular endothelial cells (HUVECs). Furthermore, we used qPCR to analyze the gene expressions and Western blot to observe protein expressions of MMP-2, MMP-14, TIMP-2, RECK, and VEGF/VEGFRs. Results: This study identified five major compounds from the water extract of D. fortunei: protocatechuic acid, caffeic acid 4-O-beta-D-glucopyranoside, 5,7 dihydroxychromone-7-O-rutinoside, neoeriocitrin, and naringin. D. fortunei was confirmed to activate in vivo angiogenesis by CAM and DIVVA assays. D. fortunei further exhibited in vitro angiogenic effects associated with cell migration, as demonstrated by the tube formation assay, transwell migration assay, and scratch wound healing assay. The extracellular MMP-2 activity was found to be dose dependently augmented both in vitro and in vivo by D. fortunei. The mRNA and protein expressions of MMP-2, and MMP-14 were increased; while the tissue inhibitor metalloproteinase-2 (TIMP-2), and reversion-inducing cysteine-rich protein with kazal motifs (RECK) were both decreased. Furthermore, D. fortunei activated the gene and protein expressions of VEGF-A, -B, and VEGFR-2, -3. Conclusion: D. fortunei increased MMP-2 activity, thereby stimulating angiogenesis and cell migration, both in vivo and in vitro, as a result of MMP-2 and TIMP-2 balance modulation and the activation of VEGF/VEGFRs expression. PMID- 30298001 TI - Evaluation of Chitosan Derivative Microparticles Encapsulating Superparamagnetic Iron Oxide and Doxorubicin as a pH-Sensitive Delivery Carrier in Hepatic Carcinoma Treatment: An in vitro Comparison Study. AB - We developed a novel, pH-sensitive drug delivery microparticle based on N palmitoyl chitosan (NPCS) to transport the superparamagnetic iron oxide (SPIO) and anticancer drug doxorubicin (DOX). The characteristics of NPCS were characterized through nuclear magnetic resonance. Our results based on testing of volume swelling in multiple pH aqueous solutions revealed that the modified chitosan had a pH-sensitive property. The morphology and size of the DOX SPIO/NPCS microparticles were investigated using transmission electron microscopy and scanning electron microscopy. The statistical result of microparticles had diameter of 185 +/- 87 nm. Surface chemical moieties of DOX-SPIO/NPCS microparticles were confirmed using attenuated total reflection Fourier transform infrared spectroscopy and indicated the existence of mostly hydrophilic groups such as -OH, -C=O, and -C-O-C-. Transmission electron microscopy revealed the dark contrast of SPIO dots encapsulated in the NPCS matrix. Nuclear magnetic resonance T2-weighted magnetic resonance imaging confirmed that the produced DOX SPIO/NPCS microparticles still exhibited T2 relaxation durations as short as 37.68 +/- 8.69 ms (under administration of 2.5 MUg/mL), which is comparable to the clinically required dosage. In the drug release profile, the DOX-SPIO/NPCS drug delivery microparticle was accelerated in an acidic environment (pH 6.5) compared with that in a basic environment. Microparticles in a cytotoxicity assay (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay) revealed that DOX-SPIO/NPCS microparticles had better antitumor ability than did free-form of DOX. Additionally, microparticles loaded with 0.5-5 MUg/mL DOX in an acidic environment (pH 6.5) demonstrated higher efficacy against Hep G2 cell growth, possibly because of the swelling effect of NPCS, resulting in volume expansion and easy drug release. Accordingly, these large DOX-SPIO/NPCS microparticles showed potential for application as a pH-sensitive drug delivery system and as chemoembolization particles for hepatic carcinoma therapy. PMID- 30298002 TI - Maprotiline Prevents Monocrotaline-Induced Pulmonary Arterial Hypertension in Rats. AB - Pulmonary arterial hypertension (PAH) is a progressive disease caused by increased pulmonary artery pressure and pulmonary vascular resistance, eventually leading to right heart failure until death. Soluble guanylate cyclase (sGC) has been regarded as an attractive drug target in treating PAH. In this study, we discovered that maprotiline, a tetracyclic antidepressant, bound to the full length recombinant sGC with a high affinity (K D = 0.307 MUM). Further study demonstrated that maprotiline concentration-dependently inhibited the proliferation of hypoxia-induced human pulmonary artery smooth muscle cells. Moreover, in a monocrotaline (MCT) rat model of PAH, maprotiline (ip, 10 mg/kg once daily) reduced pulmonary hypertension, inhibited the development of right ventricular hypertrophy and pathological changes of the pulmonary vascular remodeling. Taken together, our studies showed that maprotiline may contribute to attenuate disease progression of pulmonary hypertension. PMID- 30298004 TI - Pharmaceutical Care Increases Time in Therapeutic Range of Patients With Poor Quality of Anticoagulation With Warfarin. AB - Thromboembolic events are associated with high mortality and morbidity indexes. In this context, warfarin is the most widely prescribed oral anticoagulant agent for preventing and treating these events. This medication has a narrow therapeutic range and, consequently, patients usually have difficulty in achieving and maintaining stable target therapeutics. Some studies on the literature about oral anticoagulant management showed that pharmacists could improve the efficiency of anticoagulant therapy. However, the majority of these studies included general patients retrospectively. The aim of this study was to prospectively evaluate a pharmacist's warfarin management in patients with poor quality of anticoagulation therapy (Time in the Therapeutic Range- TTR < 50%). We included 268 patients with atrial fibrillation (AF) and without stable dose of warfarin (TTR < 50%, based on the last three values of International Normalized Ratio-INR). We followed them up for 12 weeks, INR values were evaluated and, when necessary, the dose adjustments were performed. During the first four visits, patient's INR was measured every 7 days. Then, if INR was within the target therapeutic range (INR: 2-3), the patient was asked to return in 30 days. However, if INR was out the therapeutic target, the patient was asked to return in 7 days. Adherence evaluation was measured through questionnaires and by counting the pills taken. Comparison between basal TTR (which was calculated based on the three last INR values before prospective phase) and TTR of 4 weeks (calculated by considering the INR tests from visits 0 to 4, in the prospective phase of the study) and basal TTR and TTR of 12 weeks (calculated based on the INR tests from visits 0 to 12, in the prospective phase of the study) revealed significant statistical differences (0.144 +/- 0.010 vs. 0.382 +/- 0.016; and 0.144 +/- 0.010 vs. 0.543 +/- 0.014, p < 0.001, respectively). We also observed that the mean TTR of 1 year before (retrospective phase) was lower than TTR value after 12 weeks of pharmacist-driven treatment (prospective phase) (0.320 +/- 0.015; 0.540 +/- 0.015, p < 0.001). In conclusion, pharmaceutical care was able to improve TTR values in patients with AF and poor quality of anticoagulation with warfarin. PMID- 30298003 TI - Chick Embryo: A Preclinical Model for Understanding Ischemia-Reperfusion Mechanism. AB - Ischemia-reperfusion (I/R)-related disorders, such as stroke, myocardial infarction, and peripheral vascular disease, are among the most frequent causes of disease and death. Tissue injury or death may result from the initial ischemic insult, primarily determined by the magnitude and duration of the interruption in blood supply and then by the subsequent reperfusion-induced damage. Various in vitro and in vivo models are currently available to study I/R mechanism in the brain and other tissues. However, thus far, no in ovo I/R model has been reported for understanding the I/R mechanisms and for faster drug screening. Here, we developed an in ovo Hook model of I/R by occluding and releasing the right vitelline artery of a chick embryo at 72 h of development. To validate the model and elucidate various underlying survival and death mechanisms, we employed imaging (Doppler blood flow imaging), biochemical, and blotting techniques and evaluated the cell death mechanism: autophagy and inflammation caused by I/R. In conclusion, the present model is useful in parallel with established in vitro and in vivo I/R models to understand the mechanisms of I/R development and its treatment. PMID- 30298005 TI - Effects of Valproic Acid on Cerebral Nutrient Carriers' Expression in the Rat. AB - Objective: The antiepileptic drug valproate has been shown to affect the expression of carriers for essential compounds and drugs in extracerebral tissues. The aim of the current study was to evaluate in vivo the effect of valproate treatment on the cerebral expression of carriers and selected genes of the blood-brain barrier (BBB) in the rat. Methods: Male Wistar rats were treated daily for 7 days by intraperitoneal injections of valproate (75, 150, or 300 mg/kg/day) or the vehicle. mRNA was isolated from the cerebral cortex and the hippocampus. Transcript levels of 37 genes were measured using a customized gene expression assay. Quantitative histone acetylation was evaluated by western blotting. Glucose6-phosphate (G6P) tissue levels were used as a surrogate of cerebral glucose concentrations. Results: Valproate treatment was associated with significant reduction (up to 22%; P < 0.05) in cortical and hippocampal claudin 5 normalized Slc2a1 (Glut1) mRNA expression. G6P levels were not significantly altered, but were correlated with Slc2a1 transcript levels (r = 0.499; P < 0.02). None of the other 36 screened genes were significantly affected by valproate. Cortical histone hyperacetylation indicated cerebral activity of valproate on a major pathway regulating gene expression (P < 0.02). Significance: The effect of valproate on nutrient carriers appears to be tissue-specific and even brain area specific. If validated in humans, the changes in Glut1 expression might have clinical implications in positron emission tomography (PET) imaging. Further studies are required for elucidating the relevance of these findings to the clinic. PMID- 30298006 TI - Luteolin Inhibits Vascular Smooth Muscle Cell Proliferation and Migration by Inhibiting TGFBR1 Signaling. AB - Vascular smooth muscle cell (VSMC) proliferation and migration play a critical role in the development of arterial remodeling during various vascular diseases including atherosclerosis, hypertension, and related diseases. Luteolin is a food derived flavonoid that exerts protective effects on cardiovascular diseases. Here, we investigated whether transforming growth factor-beta receptor 1 (TGFBR1) signaling underlies the inhibitory effects of luteolin on VSMC proliferation and migration. We found that luteolin reduced the proliferation and migration of VSMCs, specifically A7r5 and HASMC cells, in a dose-dependent manner, based on MTS and EdU, and Transwell and wound healing assays, respectively. We also demonstrated that it inhibited the expression of proliferation-related proteins including PCNA and Cyclin D1, as well as the migration-related proteins MMP2 and MMP9, in a dose-dependent manner by western blotting. In addition, luteolin dose dependently inhibited the phosphorylation of TGFBR1, Smad2, and Smad3. Notably, adenovirus-mediated overexpression of TGFBR1 enhanced TGFBR1, Smad2, and Smad3 activation in VSMCs and partially blocked the inhibitory effect of luteolin on TGFBR1, Smad2, and Smad3. Moreover, overexpression of TGFBR1 rescued the inhibitory effects of luteolin on the proliferation and migration of VSMCs. Additionally, molecular docking showed that this compound could dock onto an agonist binding site of TGFBR1, and that the binding energy between luteolin and TGFBR1 was -10.194 kcal/mol. Simulations of molecular dynamics showed that TGFBR1 luteolin binding was stable. Collectively, these data demonstrated that luteolin might inhibit VSMC proliferation and migration by suppressing TGFBR1 signaling. PMID- 30298007 TI - So-Cheong-Ryoung-Tang Attenuates Pulmonary Inflammation Induced by Cigarette Smoke in Bronchial Epithelial Cells and Experimental Mice. AB - So-Cheong-Ryoung-Tang is a traditionally used herbal formula for the treatment of pulmonary diseases in China, Korea, and Japan. We investigated the protective effects of So-Cheong-Ryong-Tang water extract (SCWE) in cigarette smoke concentrate (CSC) stimulated human airway epithelial cell line NCI-H292 and mice exposed cigarette smoke (CS) and lipopolysaccharide (LPS). In the CSC-stimulated NCI-H292 cells, SCWE inhibited proinflammatory cytokines in a concentration dependent manner, as evidenced by a reduction in their mRNA levels. Also, SCWE significant reduced inducible nitric oxide synthase (iNOS) expression and nuclear factor kappa B (NF-kappaB) phosphorylation in CSC-stimulated cells. The mice were exposed to CS for 1 h per day (a total of eight cigarettes per day) for 7 days and received LPS intranasally on day 5. The mice were administered a dose of SCWE (100 and 200 mg/kg) 1 h before CS exposure. In in vivo, SCWE decreased the inflammatory cell count and reduced the expression of the proinflammatory cytokines in the broncho-alveolar lavage fluid (BALF) compared with CS and LPS exposed mice. SCWE attenuated inflammatory cell infiltration in airway induced by CS and LPS exposure, and this decrease was accompanied by a reduction in the expression levels of iNOS and MMP-9 in lung tissue. The extract also inhibited the phosphorylation of inhibitor of kappa B alpha (IkappaBalpha) and NF-kappaB induced by CS and LPS exposure in lung tissue. These results suggest that SCWE may effectively inhibit airway inflammatory responses induced by CS and LPS exposure via the NF-kappaB pathway. Therefore, SCWE may be a potential treatment for airway inflammatory diseases, such as chronic obstructive pulmonary disease (COPD). PMID- 30298009 TI - Cucurbitacin B Induces Hypoglycemic Effect in Diabetic Mice by Regulation of AMP Activated Protein Kinase Alpha and Glucagon-Like Peptide-1 via Bitter Taste Receptor Signaling. AB - Taste receptors exist in several organs from tongue to colon and have diverse functions dependent on specific cell type. In enteroendocrine L-cells, stimulation of taste receptor signaling induces incretin hormones. Among incretin hormones, glucagon-like peptide-1 (GLP-1) induces insulinotropic action by activating GLP-1 receptor of pancreatic beta-cells. However, GLP-1 mimetic medicines have reported clinical side effects, such as autoimmune hepatitis, acute kidney injury, pancreatitis, and pancreatic cancer. Here, we hypothesized that if natural components in ethnomedicines can activate agonistic action of taste receptor; they may stimulate GLP-1 and therefore, could be developed as safe and applicable medicines to type 2 diabetes mellitus (T2DM) with minimal side effects. Cucurbitacin B (CuB) is composed of triterpenoid structure and its structural character, that represents bitterness, can stimulate AMP-activated protein kinase (AMPK) pathway. CuB ameliorated hyperglycemia by activating intestinal AMPK levels and by inducing plasma GLP-1 and insulin release in diabetic mice. This hypoglycemic action was decreased in dorsomorphin-injected mice and alpha-gustducin null mice. Moreover, systemic inhibition study in differentiated NCI-H716 cell line showed that CuB-mediated GLP-1 secretion was involved in activation of AMPK through alpha-gustducin and Gbetagamma-signaling of taste receptors. In summary, we conclude that, CuB represents novel hypoglycemic agents by activation of AMPK and stimulation of GLP-1 in differentiated enteroendocrine L-cells. These results suggest that taste receptor signaling-based therapeutic agents within tremendously diverse ethnomedicines, could be applied to developing therapeutics for T2DM patients. PMID- 30298010 TI - Development and Role in Therapy of Canakinumab in Adult-Onset Still's Disease. AB - Adult-onset Still's disease (AOSD) is a rare inflammatory disease of unknown etiology typically characterized by episodes of spiking fever, evanescent rash, arthralgia, leukocytosis, and hyperferritinemia. The pivotal role of interleukin (IL)-1 and other pro-inflammatory cytokines gives rise to the development of new targeted therapies. Currently, AOSD patients can benefit from efficient and well tolerated biologic agents, such as IL-1, IL-6, and tumour necrosis factor (TNF) alpha antagonists. Canakinumab, a human monoclonal anti-IL-1beta antibody, is indicated for the treatment of different autoinflammatory syndromes in adults, adolescents, and children and it has recently been approved for AOSD treatment. In this article, we summarize the structural and biochemical data describing the molecular interactions between Canakinumab and its target antigen. Some special considerations of the pharmacological properties of Canakinumab are included. We also review the safety, efficacy and tolerability of this drug for the treatment of AOSD. PMID- 30298011 TI - Generation of MicroRNA-34 Sponges and Tough Decoys for the Heart: Developments and Challenges. AB - Heart failure (HF) is a debilitating and deadly chronic disease, with almost 50% of patients with HF dying within 5 years of diagnosis. With limited effective therapies to treat or cure HF, new therapies are greatly needed. microRNAs (miRNAs) are small non-coding RNA molecules that are powerful regulators of gene expression and play a key role in almost every biological process. Disruptions in miRNA gene expression has been functionally linked to numerous diseases, including cardiovascular disease. Molecular tools for manipulating miRNA activity have been developed, and there is evidence from preclinical studies demonstrating the potential of miRNAs to be therapeutic targets for cardiovascular disease. For clinical application, miRNA sponges and tough decoys have been developed for more stable suppression and targeted delivery of the miRNA of choice. The aim of this study was to generate miRNA sponges and tough decoys to target miR-34 in the mouse heart. We present data to show that using both approaches we were unable to get significant knockdown of miR-34 or regulate miR-34 target genes in the heart in vivo. We also review recent applications of this method in the heart and discuss further considerations for optimisation in construct design and testing, and the obstacles to be overcome before they enter the clinic. PMID- 30298012 TI - A Computational Framework to Benchmark Basket Catheter Guided Ablation in Atrial Fibrillation. AB - Catheter ablation is a curative therapeutic approach for atrial fibrillation (AF). Ablation of rotational sources based on basket catheter measurements has been proposed as a promising approach in patients with persistent AF to complement pulmonary vein isolation. However, clinically reported success rates are equivocal calling for a mechanistic investigation under controlled conditions. We present a computational framework to benchmark ablation strategies considering the whole cycle from excitation propagation to electrogram acquisition and processing to virtual therapy. Fibrillation was induced in a patient-specific 3D volumetric model of the left atrium, which was homogeneously remodeled to sustain reentry. The resulting extracellular potential field was sampled using models of grid catheters as well as realistically deformed basket catheters considering the specific atrial anatomy. The virtual electrograms were processed to compute phase singularity density maps to target rotor tips with up to three circular ablations. Stable rotors were successfully induced in different regions of the homogeneously remodeled atrium showing that rotors are not constrained to unique anatomical structures or locations. Density maps of rotor tip trajectories correctly identified and located the rotors (deviation < 10 mm) based on catheter recordings only for sufficient resolution (inter-electrode distance <=3 mm) and proximity to the wall (<=10 mm). Targeting rotor sites with ablation did not stop reentries in the homogeneously remodeled atria independent from lesion size (1-7 mm radius), from linearly connecting lesions with anatomical obstacles, and from the number of rotors targeted sequentially (<=3). Our results show that phase maps derived from intracardiac electrograms can be a powerful tool to map atrial activation patterns, yet they can also be misleading due to inaccurate localization of the rotor tip depending on electrode resolution and distance to the wall. This should be considered to avoid ablating regions that are in fact free of rotor sources of AF. In our experience, ablation of rotor sites was not successful to stop fibrillation. Our comprehensive simulation framework provides the means to holistically benchmark ablation strategies in silico under consideration of all steps involved in electrogram-based therapy and, in future, could be used to study more heterogeneously remodeled disease states as well. PMID- 30298008 TI - Hydrogen Sulfide (H2S)-Releasing Compounds: Therapeutic Potential in Cardiovascular Diseases. AB - Cardiovascular disease is the main cause of death worldwide, but its pathogenesis is not yet clear. Hydrogen sulfide (H2S) is considered to be the third most important endogenous gasotransmitter in the organism after carbon monoxide and nitric oxide. It can be synthesized in mammalian tissues and can freely cross the cell membrane and exert many biological effects in various systems including cardiovascular system. More and more recent studies have supported the protective effects of endogenous H2S and exogenous H2S-releasing compounds (such as NaHS, Na2S, and GYY4137) in cardiovascular diseases, such as cardiac hypertrophy, heart failure, ischemia/reperfusion injury, and atherosclerosis. Here, we provided an up-to-date overview of the mechanistic actions of H2S as well as the therapeutic potential of various classes of H2S donors in treating cardiovascular diseases. PMID- 30298013 TI - O-GlcNAc Modification During Pregnancy: Focus on Placental Environment. AB - Successful placentation is a key event for fetal development, which commences following embryo implantation into the uterine wall, eliciting decidualization, placentation, and remodeling of blood vessels to provide physiological exchange between embryo-fetus and mother. Several signaling pathways are recruited to modulate such important processes and specific proteins that regulate placental function are a target for the glycosylation with O-linked beta-N acetylglucosamine (O-GlcNAc), or O-GlcNAcylation. This is a reversible post translational modification on nuclear and cytoplasmic proteins, mainly controlled by O-GlcNAc transferase (OGT) and O-GlcNAcase (OGA). O-GlcNAcylation has been implicated as a modulator of proteins, both in physiological and pathological conditions and, more recently, O-GlcNAc has also been shown to be an important modulator in placental tissue. In this mini-review, the interplay between O GlcNAcylation of proteins and placental function will be addressed, discussing the possible implications of this post-translational modification through placental development and pregnancy. PMID- 30298015 TI - The Validity and Between-Unit Variability of GNSS Units (STATSports Apex 10 and 18 Hz) for Measuring Distance and Peak Speed in Team Sports. AB - The aims of this study were (i) to investigate the criterion validity (vs. gold standard measurements) of the 10 and 18 Hz STATSports Apex units for measuring distances and peak speed (Vpeak) outcomes and (ii) to investigate the between unit variability. Twenty university students were enrolled in the study (age 21 +/- 2 years, weight 72 +/- 6 kg, and height 1.76 +/- 0.05 m). The criterion validity was tested by comparing the distances recorded by the units with ground truth reference (400-m trial, 128.5-m circuit, and 20-m trial). Vpeak values were compared with those determined by a gold standard criterion device (Stalker ATS Radar Gun) during a linear 20-m sprint. The distance biases for the Apex 10 Hz in the 400-m trial, 128.5-m circuit, and 20-m trial were 1.05 +/- 0.87%, 2.3 +/- 1.1%, and 1.11 +/- 0.99%, respectively, while for the Apex 18 Hz the biases were 1.17 +/- 0.73%, 2.11 +/- 1.06%, and 1.15 +/- 1.23%, respectively. Vpeak measured by the Apex 10 and 18 Hz were 26.5 +/- 2.3 km h-1 and 26.5 +/- 2.6 km h-1, respectively, with the criterion method reporting 26.3 +/- 2.4 km h-1, with a bias of 2.36 +/- 1.67% and 2.02 +/- 1.24%, respectively. This study is the first to validate and compare the STATSports Apex 10 and 18 Hz. Between-analysis (t test) for total distance and Vpeak reported non-significant differences. Apex units reported a small error of around 1-2% compared to the criterion distances during 400-m, 128.5-m circuit, 20-m trials, and Vpeak. In conclusion, both units could be used with confidence to measure these variables during training and match play. PMID- 30298014 TI - Relationship Between Morning Heart Rate Variability and Creatine Kinase Response During Intensified Training in Recreational Endurance Athletes. AB - Specific physiological responses and their relationship were analyzed in 12 recreational endurance athletes (43.8 +/- 7.9 years) during a period of intensified cycling training. Heart rate (HR), HR variability (HRV), serum creatine kinase (S-CK) and haematocrit (Hct) were measured in the mornings before (PRE) and following three consecutive days of intensified training (POST 1-3). Morning HR increased during this period (PRE: 52.2 +/- 6.7 bpm, POST 1: 58.8 +/- 7.0 bpm, POST 2: 58.5 +/- 8.1 bpm, POST 3: 57.9 +/- 7.2 bpm; F(3,33) = 11.182, p < 0.001, etap 2 = 0.554). Parasympathetic HRV indices decreased from PRE to POST (F(3,33) >= 11.588, p < 0.001, etap 2 >= 0.563), no effect was found for sympathetically modulated HRV (F(3,33) = 2.287, p = 0.101, etap 2 = 0.203). Hct decreased (PRE: 49.9 +/- 4.0%, POST 1: 46.5 +/- 5.1%, POST 2: 45.5 +/- 3.8%, POST 3: 43.2 +/- 3.4%; F(3,33) = 11.909, p < 0.001, etap 2 = 0.520) and S-CK increased during the training period (PRE: 90.0 +/- 32.1 U/L, POST 1: 334.7 +/- 487.6 U/L, POST 2: 260.1 +/- 303.4 U/L, POST 3: 225.1 +/- 258.8 U/L; F(3,33) = 3.996, p = 0.017, etap 2 = 0.285). S-CK release was associated with HR (r = 0.453, p = 0.002, n = 44), RMSSD (r = -0.494, p = 0.001, n = 44) and HF-Power (r = -0.490, p = 0.001, n = 44). A period of intensified training was associated with haemodilution, parasympathetic withdrawal and S-CK-increase. Cardiac autonomic control at morning rest correlated with the S-CK-release; and thus, may serve as a practical mean to complementary monitor and prescribe training load in this population. PMID- 30298016 TI - The Influence of MicroRNAs on Mitochondrial Calcium. AB - Abnormal mitochondrial calcium ([Ca2+]m) handling and energy deficiency results in cellular dysfunction and cell death. Recent studies suggest that nuclear encoded microRNAs (miRNA) are able to translocate in to the mitochondrial compartment, and modulate mitochondrial activities, including [Ca2+]m uptake. Apart from this subset of miRNAs, there are several miRNAs that have been reported to target genes that play a role in maintaining [Ca2+]m levels in the cytoplasm. It is imperative to validate miRNAs that alter [Ca2+]m handling, and thereby alter cellular fate. The focus of this review is to highlight the mitochondrial miRNAs (MitomiRs), and other cytosolic miRNAs that target mRNAs which play an important role in [Ca2+]m handling. PMID- 30298017 TI - The Relation Between Capillary Transit Times and Hemoglobin Saturation Heterogeneity. Part 2: Capillary Networks. AB - Brain metabolism is highly dependent on continuous oxygen supply. Cortical microvascular networks exhibit heterogeneous blood flow, leading to non-uniform tissue oxygenation and capillary hemoglobin saturation. We recently proposed capillary outflow saturation heterogeneity (COSH) to represent effects of heterogeneity on oxygen supply to tissue regions most vulnerable to hypoxia, and showed that diffusive oxygen exchange among red blood cells within capillaries and among capillaries (diffusive interaction) significantly reduces COSH in simplified geometrical configurations. Here, numerical simulations of oxygen transport in capillary network geometries derived from mouse somatosensory cortex are presented. Diffusive interaction was found to reduce COSH by 41 to 62% compared to simulations where diffusive interaction was excluded. Hemoglobin saturation drop across the microvascular network is strongly correlated with red blood cell transit time, but the coefficient of variation of saturation drop is approximately one third lower. Unexpectedly, the radius of the tissue cylinder supplied by a capillary correlates weakly with the anatomical tissue cylinder radius, but strongly with hemoglobin saturation. Thus, diffusive interaction contributes greatly to the microcirculation's ability to achieve tissue oxygenation, despite heterogeneous capillary transit time and hematocrit distribution. These findings provide insight into the effects of cerebral small vessel disease on tissue oxygenation and brain function. PMID- 30298018 TI - Reducing Error in ECG Forward Simulations With Improved Source Sampling. AB - A continuing challenge in validating electrocardiographic imaging (ECGI) is the persistent error in the associated forward problem observed in experimental studies. One possible cause of this error is insufficient representation of the cardiac sources; cardiac source measurements often sample only the ventricular epicardium, ignoring the endocardium and the atria. We hypothesize that measurements that completely cover the pericardial surface are required for accurate forward solutions. In this study, we used simulated and measured cardiac potentials to test the effect of different levels of spatial source sampling on the forward simulation. Not surprisingly, increasing the source sampling over the atria reduced the average error of the forward simulations, but some sampling strategies were more effective than others. Uniform and random distributions of samples across the atrial surface were the most efficient strategies in terms of lowest error with the fewest sampling locations, whereas "single direction" strategies, i.e., adding to the atrioventricular (AV) plane or atrial roof only, were the least efficient. Complete sampling of the atria is needed to eliminate errors from missing cardiac sources, but while high density sampling that covers the entire atria yields the best results, adding as few as 11 electrodes on the atria can significantly reduce these errors. Future validation studies of the ECG forward simulations should use a cardiac source sampling that takes these considerations into account, which will, in turn, improve validation and understanding of ECGI. PMID- 30298019 TI - The Correlation Between Circulating Ghrelin and Insulin Resistance in Obesity: A Meta-Analysis. AB - Background: Ghrelin, a peptide mainly produced by stomach X-A cells. It plays a pivotal role in the regulation of food intake and energy metabolism, including glucose metabolism and insulin sensitivity. However, the correlation between circulating ghrelin levels and insulin resistance in obesity remained uncertain. This meta-analysis aimed to clarify the association between ghrelin and IR in obesity. Methods: A systematic literature search was performed using PubMed, EMBASE, Cochrane Library and Web of Science until April 18, 2018 with the keywords "ghrelin" and "insulin resistance." Two independent reviewers selected studies and assessed data. Subgroup analyses were performed to search for sources of heterogeneity. Funnel plots and Egger's test were used to detect publication bias. A random-effects model was used to calculate the pooled effect size. Results: Ten studies with 546 participants were included in this meta-analysis. We found that ghrelin levels were negatively correlated with IR in obese individuals. (r = -0.31; 95% CI: -0.45 to -0.18). Subgroup analysis revealed that circulating ghrelin levels were significantly negatively correlated with IR in people with normal fasting blood glucose (FBG) (<6.9 mmol/dl) (r = -0.28; 95% CI: -0.47 to -0.09, I 2 = 39.5%), while there was no relationship between circulating ghrelin levels and IR in the high FBG group (>6.9 mmol/dl) (r = -0.15; 95% CI: 0.33 to 0.03, I 2 = 0.0%). Publication bias was insignificant (Egger's test: P = 0.425). Conclusion: In obesity, circulating ghrelin levels were significantly negative correlated with insulin resistance in individuals with normal fasting blood glucose. PMID- 30298020 TI - Fibrogenic Secretome of Sirtuin 1-Deficient Endothelial Cells: Wnt, Notch and Glycocalyx Rheostat. AB - Sirtuins (SIRT) are ubiquitous histone and protein deacetylases and a member of this family, SIRT1, is the best-studied one. Its functions in endothelial cells encompass branching angiogenesis, activation of endothelial nitric oxide synthase, regulation of proapoptotic and proinflammatory pathways, among others. Defective SIRT1 activity has been described in various cardiovascular, renal diseases and in aging-associated conditions. Therefore, understanding of SIRT1 deficient, endothelial dysfunctional phenotype has much to offer clinically. Here, we summarize recent studies by several investigative teams of the characteristics of models of global endothelial SIRT1 deficiency, the causes of facilitative development of fibrosis in these conditions, dissect the protein composition of the aberrant secretome of SIRT1-deficient endothelial cells and present several components of this aberrant secretome that are involved in fibrogenesis via activation of fibroblasts to myofibroblasts. These include ligands of Wnt and Notch pathways, as well as proteolytic fragments of glycocalyx core protein, syndecan-4. The latter finding is crucial for understanding the degradation of glycocalyx that accompanies SIRT1 deficiency. This spectrum of abnormalities associated with SIRT1 deficiency in endothelial cells is essential for understanding the origins and features of endothelial dysfunction in a host of cardiovascular and renal diseases. PMID- 30298021 TI - Transcriptome Analysis Provides Insights Into the Adaptive Responses to Hypoxia of a Schizothoracine Fish (Gymnocypris eckloni). AB - The schizothoracine fish endemic to the Qinghai-Tibetan Plateau are comparatively well adapted to aquatic environments with low oxygen partial pressures. However, few studies have used transcriptomic profiling to investigate the adaptive responses of schizothoracine fish tissues to hypoxic stress. This study compared the transcriptomes of Gymnocypris eckloni subjected to 72 h of hypoxia (Dissolved oxygen, DO = 3.0 +/- 0.1 mg/L) to those of G. eckloni under normoxia (DO = 8.4 +/ 0.1 mg/L). To identify the potential genes and pathways activated in response to hypoxic stress, we collected muscle, liver, brain, heart, and blood samples from normoxic and hypoxic fish for RNA-Seq analysis. We annotated 337,481 gene fragments. Of these, 462 were differentially expressed in the hypoxic fish as compared to the normoxic fish. Under hypoxia, the transcriptomic profiles of the tissues differed, with muscle the most strongly affected by hypoxia. Our data indicated that G. eckloni underwent adaptive changes in gene expression in response to hypoxia. Several strategies used by G. eckloni to cope with hypoxia were similar to those used by other fish, including a switch from aerobic oxidation to anaerobic glycolysis and the suppression of major energy-requiring processes. However, G. eckloni used an additional distinct strategy to survive hypoxic environments: a strengthening of the antioxidant system and minimization of ischemic injury. Here, we identified several pathways and related genes involved in the hypoxic response of the schizothoracine fish. This study provides insights into the mechanisms used by schizothoracine fish to adapt to hypoxic environments. PMID- 30298022 TI - Psychiatric Disorders in Refugees and Internally Displaced Persons After Forced Displacement: A Systematic Review. AB - Background: Protracted armed conflicts not only shape political, legal, and socio economic structures, but also have a lasting impact on people's human migration. In 2017, the United Nations High Commissioner for Refugees reported an unprecedented number of 65.6 million individuals who were displaced worldwide as a result of armed conflicts. To date, however, little is known about these people's mental health status. Therefore, we conducted a systematic review of the prevalence of psychiatric disorders among forcibly displaced populations in settings of armed conflicts. Methods: We undertook a database search using Medline, PsycINFO, PILOTS, and the Cochrane Library, using the following keywords and their appropriate synonyms to identify relevant articles for possible inclusion: "mental health," "refugees," "internally displaced people," "survey," and "war." This search was limited to original articles, systematic reviews, and meta-analyses published after 1980. We reviewed studies with prevalence rates of common psychiatric disorders-mood and anxiety disorders, psychotic disorders, personality disorders, substance abuse, and suicidality-among adult internally displaced persons (IDPs) and refugees afflicted by armed conflicts. Results: The search initially yielded 915 articles. Of these references 38 studies were eligible and provided data for a total of 39,518 adult IDPs and refugees from 21 countries. The highest prevalence were for reported for post-traumatic stress disorder (3-88%), depression (5-80%), and anxiety disorders (1-81%) with large variation. Only 12 original articles reported about other mental disorders. Conclusions: These results show a substantial lack of data concerning the wider extent of psychiatric disability among people living in protracted displacement situations. Ambitious assessment programs are needed to support the implementation of sustainable global mental health policies in war-torn countries. Finally, there is an urgent need for large-scale interventions that address psychiatric disorders in refugees and internally displaced persons after displacement. PMID- 30298024 TI - Protocol for the REVISIT-BPD Trial, a Randomized Controlled Trial Testing the Effectiveness of an Internet-Based Self-Management Intervention in the Treatment of Borderline Personality Disorder (BPD). AB - Introduction: Borderline Personality Disorder (BPD) is a prevalent condition that is often under-treated. This is partly because very few psychotherapists offer treatment for this disabling disorder. Internet-based self-management interventions could contribute to reducing the treatment gap but-mainly due to safety concerns-these have never been tested for BPD in controlled trials. Methods: Patients with BPD will be recruited primarily via the internet and randomized to two groups: care as usual (CAU) alone) or the self-management intervention priovi(r) in addition to CAU. At the end of the diagnostic interview, all participants will discuss an emergency plan. The main outcome measure is the clinician-rated symptom severity using the BPD Severity Index (BPDSI). Secondary outcome measures include a range of self-reported scales, an SCID-diagnosis of BPD and several safety parameters including serious adverse events (e.g., a life-threatening event, hospitalization or suicide attempt). Discussion: This trial will evaluate the effectiveness of the self-management intervention, priovi, in reducing symptoms of BPD. It will also assess the safety of its use in this target population. If successful, this intervention would be the first comprehensive internet intervention for the treatment of BPD and complement the wide range of internet interventions effective in treating other mental disorders, particularly depression and anxiety disorders.

PMID- 30298023 TI - Putative Astroglial Dysfunction in Schizophrenia: A Meta-Analysis of 1H-MRS Studies of Medial Prefrontal Myo-Inositol. AB - Background: Several lines of evidence support a role for astroglial pathology in schizophrenia. Myo-inositol is particularly abundant in astroglia. Many small sized studies have reported on myo-inositol concentration in schizophrenia, but to date these have not been pooled to estimate a collective effect size. Methods: We reviewed all proton magnetic resonance spectroscopy (1H-MRS) studies reporting myo-inositol values for patients satisfying DSM or ICD based criteria for schizophrenia in comparison to a healthy controls group in the medial prefrontal cortex published until February 2018. A random-effects model was used to calculate the pooled effect size using metafor package. A meta-regression analysis of moderator variables was also undertaken. Results: The literature search identified 19 studies published with a total sample size of 585 controls, 561 patients with schizophrenia. Patients with schizophrenia had significantly reduced medial prefrontal myo-inositol compared to controls (RFX standardized mean difference = 0.19, 95% CI [0.05-0.32], z = 2.72, p = 0.0067; heterogeneity p = 0.09). Studies with more female patients reported more notable schizophrenia related reduction in myo-inositol (z = 2.53, p = 0.011). Discussion: We report a small, but significant reduction in myo-inositol concentration in the medial prefrontal cortex in schizophrenia. The size of the reported effect indicates that the biological pathways affecting the astroglia are likely to operate only in a subset of patients with schizophrenia. MRS myo-inositol could be a useful tool to stratify and investigate such patients. PMID- 30298025 TI - Clinical Perspective on Passive Audio Vocal Measurement in the Evaluation of Selective Mutism. AB - Selective Mutism (SM) is an anxiety disorder often diagnosed in early childhood and characterized by persistent failure to speak in certain social situations but not others. Diagnosing SM and monitoring treatment response can be quite complex, due in part to changing definitions of and scarcity of research about the disorder. Subjective self-reports and parent/teacher interviews can complicate SM diagnosis and therapy, given that similar speech problems of etiologically heterogeneous origin can be attributed to SM. The present perspective discusses the potential for passive audio capture to help overcome psychiatry's current lack of objective and quantifiable assessments in the context of SM. We present supportive evidence from two pilot studies indicating the feasibility of using a digital wearable device to quantify child vocalization features affected by SM. We also highlight comparative analyses of passive audio capture and its potential to enhance diagnostic characterizations for SM, as well as possible limitations of such technologies. PMID- 30298027 TI - Use of Baclofen for Alcohol Use Disorders in the United States. PMID- 30298026 TI - Interoceptive Anxiety and Body Representation in Anorexia Nervosa. AB - Individuals with anorexia nervosa (AN) typically display anxious traits prior to the onset of food avoidance and weight loss that characterize the disorder. Meal associated anxiety is an especially common clinical feature in these patients, and heightened sensitivity to sympathetically mediated interoceptive sensations has also been observed. However, it remains unclear how heightened interoceptive sensitivity relates to experiences of anxiety before and after meals. To investigate this relationship, we experimentally induced anxiety and panic symptoms with isoproterenol, a peripheral sympathetic agonist similar to adrenaline, across several different conditions: during panic provocation, during anticipation of a 1,000 Calorie meal, and after meal consumption. Fifteen AN and 15 age- and sex-matched healthy comparisons received bolus infusions of isoproterenol and saline in a double-blinded, randomized design. Participants rated anxiety symptoms after each infusion, completed panic rating scales, and traced the location of perceived palpitations on a manikin to index interoceptive "body map" representation. The AN group reported significantly elevated anxiety relative to healthy comparisons during infusions before and after the meal, but surprisingly, not during panic provocation. These symptoms were accompanied by geographical differences in patterns of perceived heartbeat sensations across each condition. In particular, the AN group localized heartbeat sensations disproportionately to the chest during meal related saline infusions, when no cardiorespiratory modulation actually occurred. The AN group also showed a trend toward higher panic attack rates during the meal anticipation period. Correcting for anxiety levels reported during saline infusions abolished group differences in anxiety change across all conditions, suggesting a significant contribution of anxious traits in AN. The observation of meal related "visceral illusions" provides further evidence that AN is associated with abnormal interoceptive representation of the heartbeat and suggests that meal consumption, particularly when anticipated, preferentially alters the processing of interoception related signals in AN. PMID- 30298030 TI - Dietary Behavior: An Interdisciplinary Conceptual Analysis and Taxonomy. AB - Background: Dietary behavior encompasses many aspects, terms for which are used inconsistently across different disciplines and research traditions. This hampers communication and comparison across disciplines and impedes the development of a cumulative science. We describe the conceptual analysis of the fuzzy umbrella concept "dietary behavior" and present the development of an interdisciplinary taxonomy of dietary behavior. Methods: A four-phase multi-method approach was employed. Input was provided by 76 scholars involved in an international research project focusing on the determinants of dietary behavior. Input was collected from the scholars via an online mind mapping procedure. After structuring, condensing, and categorizing this input into a compact taxonomy, the result was presented to all scholars, discussed extensively, and adapted. A second revision round was then conducted among a core working group. Results: A total of 145 distinct entries were made in the original mind mapping procedure. The subsequent steps allowed us to reduce and condense the taxonomy into a final product consisting of 34 terms organized into three main categories: Food Choice, Eating Behavior, and Dietary Intake/Nutrition. In a live discussion session attended by 50 of the scholars involved in the development of the taxonomy, it was judged to adequately reflect their input and to be a valid and useful starting point for interdisciplinary understanding and collaboration. Conclusion: The current taxonomy can be used as a tool to facilitate understanding and cooperation between different disciplines investigating dietary behavior, which may contribute to a more successful approach to tackling the complex public health challenges faced by the field. The taxonomy need not be viewed as a final product, but can continue to grow in depth and width as additional experts provide their input. PMID- 30298029 TI - Comparison of the Personality Traits of Male and Female BASE Jumpers. AB - BASE jumping is an extreme adventure sport which consists of jumping from a fixed object with specially adapted parachutes. A few studies of the personality of BASE jumpers have been conducted, but little is known about how the women in this sport compare to the men. The purpose of this study is to compare the personality traits among a sample of men and women who are experienced BASE jumpers, as this provides an interesting and important opportunity to better understand the motivation for extreme sports. Eighty-three participants completed the Temperament and Character Inventory the day before the jump at the New River Gorge Bridge Day BASE Jumping event, West Virginia, United States. The sample included 64 men and 19 women. Results show that men and women BASE jumpers shared similar personality traits both in terms of temperament and character, except for the character trait of cooperativeness on which women scored higher than men. This suggests that the basic drive for participation in extreme sports is self regulation of personal emotional drives and needs for self-actualization, rather than to oppose social pressure or cultural bias against female participation. These findings are discussed in relation with other studies conducted among extreme athletes and in terms of congruence between personality and activity. PMID- 30298031 TI - The Effect of Pairing Individuals With Different Social Skills on Interpersonal Motor Coordination. AB - Previous studies have demonstrated that combining individuals with different social skills affects performance in rhythmic interpersonal motor coordination, with individuals with lower social skills, such as individuals with autism spectrum disorder or schizophrenia, being found to follow the actions of partners with higher social skills. In this study, we investigated whether this finding could be generalized among pairs of individuals without disability. To perform this, we applied an interpersonal motor coordination task that required participants to perform rhythmic movements featuring an interpersonal relative phase pattern of 90 degrees . We did not assign the two roles (i.e., the preceding and following roles) to the participants, meaning they were forced to determine which roles to adopt by observing each other's movements, without verbal communication. Individual social skills were measured using the autism spectrum quotient (AQ). We found that pairs of participants with widely differing AQ scores performed better than did pairs with similar AQ scores. Most notably, the participants with higher AQ scores tended to precede their partners in the present task, which is the opposite result to that reported in previous studies. Our findings suggest that paring individuals without disability according to their social skills influences their interpersonal coordination performance in tasks wherein they must determine the preceding and following roles themselves. PMID- 30298028 TI - Gray Matter Structural Alterations in Social Anxiety Disorder: A Voxel-Based Meta Analysis. AB - The current insight into the neurobiological pathogenesis underlying social anxiety disorder (SAD) is still rather limited. We implemented a meta-analysis to explore the neuroanatomical basis of SAD. We undertook a systematic search of studies comparing gray matter volume (GMV) differences between SAD patients and healthy controls (HC) using a whole-brain voxel-based morphometry (VBM) approach. The anisotropic effect size version of seed-based d mapping (AES-SDM) meta analysis was conducted to explore the GMV differences of SAD patients compared with HC. We included eleven studies with 470 SAD patients and 522 HC in the current meta-analysis. In the main meta-analysis, relative to HC, SAD patients showed larger GMVs in the left precuneus, right middle occipital gyrus (MOG) and supplementary motor area (SMA), as well as smaller GMV in the left putamen. In the subgroup analyses, compared with controls, adult patients (age >= 18 years) with SAD exhibited larger GMVs in the left precuneus, right superior frontal gyrus (SFG), angular gyrus, middle temporal gyrus (MTG), MOG and SMA, as well as a smaller GMV in the left thalamus; SAD patients without comorbid depressive disorder exhibited larger GMVs in the left superior parietal gyrus and precuneus, right inferior temporal gyrus, fusiform gyrus, MTG and superior temporal gyrus (STG), as well as a smaller GMV in the bilateral thalami; and currently drug-free patients with SAD exhibited a smaller GMV in the left thalamus compared with HC while no larger GMVs were found. For SAD patients with different clinical features, our study revealed directionally consistent larger cortical GMVs and smaller subcortical GMVs, including locationally consistent larger precuneus and thalamic deficits in the left brain. Age, comorbid depressive disorder and concomitant medication use of the patients might be potential confounders of SAD at the neuroanatomical level. PMID- 30298032 TI - Counseling and Psychology Student Experiences of Personal Therapy: A Critical Interpretive Synthesis. AB - Background: Committing to attendance at personal therapy sessions is frequently either mandated or encouraged in many different types of therapeutic trainings across allied health, psychotherapy, social work and counseling. The small number of published accounts have indicated that student experiences of personal therapy can be mixed. Methods: The project examined contemporary interview based research about student experience of personal therapy during training using Critical Interpretive Synthesis method. Ten papers were found which met the search criteria. The papers included a total of 89 participants (75 F). Results: The results comprised 12 themes derived from 89 meaning units gleaned from student experiences presented in the research studies. These were used to inform a synthesizing statement here truncated as follows: Beginning therapy is challenging for some students, especially when attendance is mandatory. However, students can experience transformative change by the end of the process, even if they commence the work in a guarded way. Multiple problems can arise in the process of attending therapy as a student, and it can be difficult for a student to know what to do if these challenges are overwhelming. Attending personal therapy brings rich learnings which can be applied in clinical work but can also positively impact learning in the course, and lifelong personal development. The process can enhance the student's understanding of what the client may experience in the therapeutic journey. Conclusions: Attending personal therapy during training is not a straightforward process for all students. Course leaders and trainers need to be mindful of the possibility that students will struggle with the personal therapy requirement. Course and professional bodies should regularly review personal therapy requirements, being clear about the aims; remaining attuned to the student experience. PMID- 30298033 TI - Self-Regulation Shift Theory: A Dynamic Personal Agency Approach to Recovery Capital and Methodological Suggestions. AB - Recovery capital highlights person and environmental resources associated with overcoming significant life challenges. This paper utilizes social cognitive theory as a framework for understanding how recovery capital functions in trauma adaptation. This theory outlines the bidirectional, dynamic interactions among person (e.g., cognitive and affective), behavioral (e.g., problem focused coping), and environmental variables (i.e., triadic reciprocal determinism). The value of this approach to understanding human adaptation to trauma is that it targets the self-regulatory processes that unfold for trauma survivors as they attempt to put their lives back together. Self-regulation shift theory (SRST), as an extension to social cognitive theory, is offered to explain how self regulation is involved in both positive and negative adjustment. The theory uses a dynamical systems approach and highlights the mechanisms related to non-linear shifts in both positive and negative trauma recovery. According to SRST, trauma recovery may not be linear with threshold shifts (i.e., bifurcations) from one organized state (broken self) to another (empowered self). Coping self-efficacy perceptions are a critical factor influencing these threshold shifts. This paper concludes with a brief review of study designs and analytic procedures that can facilitate the application of non-linear dynamic research in this area. PMID- 30298034 TI - Investigating Humor in Social Interaction in People With Intellectual Disabilities: A Systematic Review of the Literature. AB - Background: Humor, both producing and appreciating, underpins positive social interactions. It acts as a facilitator of communication. There are clear links to wellbeing that go along with this form of social engagement. However, humor appears to be a seldom studied, cross-disciplinary area of investigation when applied to people with an intellectual disability. This review collates the current state of knowledge regarding the role of humor behavior in the social interactions of people with intellectual disabilities and their carers. Method: A systematic review utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was completed, which aimed to explore the current state of knowledge and quality of empirical evidence relating to humor in people with intellectual disabilities. Following this, articles were grouped thematically and summarized. A comprehensive search of four electronic databases (1954-2017) and additional search strategies yielded 32 articles which met the final inclusion criteria. Results: Humor played a significant positive and negative role in the social interactions of people with intellectual disabilities. Research had investigated humor in the classroom and humor expression in different groups including those with autism, Down syndrome, Angelman syndrome, Williams syndrome, and Rett syndrome. Few investigations directly studied humor appreciation and comprehension. Humor comprehension was reportedly supported by gestures. Some groups with intellectual disabilities found non-literal humor (e.g., sarcasm, irony) more difficult to understand, which may affect social relationships. Various types of humor were found to be appreciated. The role of humor in relationship development, social facilitation, creativity, and stigma had all received some limited attention. Humor also played a role for carer groups in coping with and enjoying the caring role. Research varied in quality with few experimental studies and mainly quasi-experimental and well-conducted, qualitative studies. Conclusions: This review revealed the importance of humor behavior in many aspects of the social lives of people with intellectual disabilities. Limited disparate research exists pertaining to humor in this group, suggesting the need for further robust research in this area, including more high quality primary research in the areas of humor production, appreciation, comprehension, and stigma. PMID- 30298035 TI - Effectiveness of a Positive Parental Practices Training Program for Chilean Preschoolers' Families: A Randomized Controlled Trial. AB - Background: Evidence for the effectiveness of parental training as a strategy for promotion of positive parental practices and prevention of child behavior problems in low and middle income countries is not conclusive. This study aims to assess the effectiveness of a universal positive parental training program designed for this context, "Dia a Dia" UdeC (c) ("Day by Day" University of Concepcion), in Chilean preschoolers' families (3-6 years old children). Methods: A cluster randomized controlled trial (cRCT) was carried out in 19 preschool education centers. There were two treatment arms: 10 centers (including 178 families) were randomly assigned to the intervention group and nine centers (including 154 families) were assigned to the waiting list control condition. Intervention groups received Day by Day UdeC, a six group sessions program for parents, including two group sessions for preschool educators, focused in affective communication; daily and child-directed play; directed attention; routines and transitions; reinforcement and incentive programs; planned inattention-ignore and time out; and logical consequences. Parental practices, parental satisfaction, and presence of children behavioral problems were examined at two-time points: T1 (4 weeks before intervention) and T2 (5-6 weeks after intervention). Results: Intention-to-treat analysis shows a reduction in physical punishment and an increase in parental involvement, as well as a reduction in children behavioral problems. A per-protocol analysis revealed an additional effect: increase in observed parental practices. Conclusion: This cRCT provided evidence for the effectiveness of a parental training program for the promotion of positive parental practices in low and middle income countries. The observed effects of the program in decreasing physical punishment and children's behavioral problems make it a promising strategy for prevention purposes.

PMID- 30298036 TI - Neural Underpinnings of the Perception of Emotional States Derived From Biological Human Motion: A Review of Neuroimaging Research. AB - Research on the perception of biological human motion shows that people are able to infer emotional states by observing body movements. This article reviews the methodology applied in fMRI research on the neural representation of such emotion perception. Specifically, we ask how different stimulus qualities of bodily expressions, individual emotional valence, and task instructions may affect the neural representation of an emotional scene. The review demonstrates the involvement of a variety of brain areas, thereby indicating how well the human brain is adjusted to navigate in multiple social situations. All stimulus categories (i.e., full-light body displays, point-light displays, and avatars) can induce an emotional percept and are associated with increased activation in an extensive neural network. This network seems to be organized around areas belonging to the so-called action observation network (PMC, IFG, and IPL) and the mentalizing network (TPJ, TP, dmPFC, and lOFC) as well as areas processing body form and motion (e.g., EBA, FBA, and pSTS). Furthermore, emotion-processing brain sites such as the amygdala and the hypothalamus seem to play an important role during the observation of emotional body expressions. Whereas most brain regions clearly display an increased response to emotional body movements in general, some structures respond selectively to negative valence. Moreover, neural activation seems to depend on task characteristics, indicating that certain structures are activated even when attention is shifted away from emotional body movements. PMID- 30298037 TI - The Relationship Between Improvement in Insomnia Severity and Long-Term Outcomes in the Treatment of Chronic Fatigue. AB - Background: The current treatments of choice for patients with chronic fatigue are moderately effective. One way to advance treatments is identifying process variables associated with good treatment outcomes. There is little knowledge regarding a possible association between insomnia and long-term outcomes in the treatment of chronic fatigue. Aims: Testing whether (1) improvement in insomnia is associated with improvement in levels of fatigue at 1-year follow-up, and (2) if such a relationship remains when controlling for improvement in levels of anxiety and depression, and pain in patients with chronic fatigue. Methods: Patients having been on sick leave 8 weeks or more due to chronic fatigue were referred to a return-to-work program. They received an intensive 3.5-week inpatient treatment program based on acceptance and commitment therapy (ACT). Before treatment and at 1-year follow-up the patients completed questionnaires assessing levels of insomnia severity, pain, anxiety and depression, and fatigue. Results: A regression analysis found that changes in insomnia-severity were associated with changes in fatigue-levels at 1-year follow-up. When changes in levels of anxiety and depression were entered in the regression analysis, anxiety and depression was significantly associated with levels of fatigue but insomnia was not. The association between anxiety and depression and fatigue was at a trend level when pain was entered into the model. Conclusion: Long-term improvement in insomnia severity was significantly associated with long-term improvement in chronic fatigue, but not independently of long-term improvement in anxiety and depression, and pain.

AB - Young children's everyday helping in the home has received relatively little attention in research on prosocial behavior. Nevertheless, key features such as young children's cheerful participation in chores around the home, including in ways that make accomplishing these chores more difficult for parents, can reveal important facets of early prosocial development. The present study reports the results of an Internet (MTurk) survey of over 500 families with children aged 1-4 years about their children's prosocial tendencies, participation in nine common chores, whether children's helping attempts were helpful or not, and attributions about children's motives for helping. Consistent with much prior research, parents reported that children became more prosocial with age. The majority of parents reported children's participation in everyday helping is at times unhelpful. Parents attributed children's helping to a variety of motives and these too, changed with age. Fathers had somewhat different perceptions of children's everyday helping than mothers. Results are discussed in terms of how understanding everyday helping can contribute to ongoing debates in the literature about the roots of prosocial behavior. PMID- 30298038 TI - High Schizotypal Individuals Are More Creative? The Mediation Roles of Overinclusive Thinking and Cognitive Inhibition. AB - Although a theoretical link between positive schizotypy and heightened creativity has been established in the literature, little empirical research has been conducted to examine the underlying cognitive processes that contribute to this association. In addition, previous studies found a negative relationship between positive schizotypy and cognitive inhibition; however, they often used the paradigm of latent inhibition. This study used the paradigm of prepotent response inhibition indicated by Stroop interference effect and examined the mediation effects of overinclusive thinking (OT) and cognitive inhibition on the creativity of schizotypal individuals. Two groups of low and high schizotypal individuals (N = 78) participated in the study. Each participant completed one OT task, one color-word Stroop task, three other executive functioning (EF) control tasks, and two creativity tasks. The results indicated that the high schizotypal group outperformed the low schizotypal group in the creativity tasks. They also exhibited higher OT as indicated by faster reaction time and higher cognitive inhibition as indicated by lower Stroop interference effect. Further, participant's levels of OT and cognitive inhibition partially mediated the relationship between schizotypy and creativity. The results were discussed under the context of schizotypy and creativity research and implications for rehabitation were further provided. PMID- 30298040 TI - Engaging in Creativity Broadens Attentional Scope. AB - Previous studies have shown that creativity is enhanced by a broad attentional scope, defined as an ability to utilize peripheral stimuli and process information globally. We propose that the reverse relationship also holds, and that breadth of attention also is a consequence of engaging in a creative activity. In Study 1, participants showed increased breadth of attention in a visual scanning task after performing a divergent thinking task as opposed to an analytic thinking task. In Study 2, participants recognized peripheral stimuli displayed during the task better after performing a divergent thinking task as compared to an analytic task, whereas recognition performance of participants performing a task that involves a mix of divergent and analytic thinking (the Remote Associates Test) fell in between. Additionally, in Study 2 (but not in Study 1), breadth of attention was positively correlated with performance in a divergent thinking task, but not with performance in an analytic thinking task. Our findings suggest that the adjustment of the cognitive system to task demands manifests at a very basic, perceptual level, through changes in the breadth of visual attention. This paper contributes a new, motivational perspective on attentional breadth and discusses it as a result of adjusting cognitive processing to the task requirements, which contributes to effective self regulation. PMID- 30298041 TI - The Buffering Effect of Machiavellianism on the Relationship Between Role Conflict and Counterproductive Work Behavior. AB - Considering the destructive effects of counterproductive work behavior (CWB) in the workplace, scholars have put much effort into revealing its antecedents. The purpose of this paper is to examine how Machiavellianism helps mitigate the effect of role conflict on CWB in China. Using data collected from three phases, this research revealed that role conflict had a positive effect on CWB via emotional exhaustion. Machiavellianism moderated the relationship between role conflict and emotional exhaustion, such that this relationship got weaker for employees with higher Machiavellianism. Furthermore, Machiavellianism moderated the relationship between role conflict and CWB via emotional exhaustion, as such, it became weaker for employees with high Machiavellianism. PMID- 30298042 TI - Let's Read a Poem! What Type of Poetry Boosts Creativity? AB - Poetry is one of the most creative uses of language. Yet the influence of poetry on creativity has received little attention. The present research aimed to determine how the reception of different types of poetry affect creativity levels. In two experimental studies, participants were assigned to two conditions: poetry reading and non-poetic text reading. Participants read poems (Study 1 = narrative/open metaphors; Study 2 = descriptive/conventional metaphors) or control pieces of non-poetic text. Before and after the reading manipulation, participants were given a test to determine levels of divergent thinking (DT; i.e., fluency, flexibility, and originality). Additionally, in both studies, the impact of frequent contact with poetry was examined. In Study 1 (N = 107), participants showed increased fluency and flexibility after reading a narrative poem, while participants who read the non-poetic text showed a decrease in fluency and originality. In Study 2 (N = 131) reception of conventional, closed metaphorization significantly lowered fluency and flexibility of thinking (compared to reading non-poetic text). The most critical finding was that poetry exposure could either increase or decrease creativity level depending on the type of poetic metaphors and style of poetic narration. Furthermore, results indicate that long-term exposure to poetry is associated with creativity. This interest in poetry can be explained by an ability to immerse oneself in a poetry content (i.e., a type of empathy) and the need for cognitive stimulation. Thus, this paper contributes a new perspective on exposure to poetry in the context of creativity and discusses possible individual differences that may affect how this type of art is received. However, future research is necessary to examine these associations further. PMID- 30298043 TI - Jamaican Mothers' Perceptions of Children's Strategies for Resisting Parental Rules and Requests. AB - Research on Jamaican socialization of children has primarily focused on parental discipline practices. Little is known about children's responses to parental attempts to control their behavior. The present study investigated mothers' perceptions of children's strategies for resisting their rules and requests. Thirty mothers living in Kingston and St. Andrew, Jamaica, participated in a 1- to 1.5-h semi-structured, open-ended interview regarding their 8- to 12-year-old children. Mothers reported that their children's resistance strategies included assertive refusal, arguing, ignoring/avoiding, attitude, and negotiation. Most mothers disapproved of their children's actions and responded with power assertive strategies such as physical punishment, psychological control, forced compliance, and threats. Few mothers responded with autonomy support strategies including accommodation and reasoning. The findings provided insight into the ways Jamaican children use their agency to protect their autonomy despite their mothers' greater power, and the relational nature of children's influence on their mothers' behaviors and reactions. More research is needed to expand our knowledge of child agency in Afro-Caribbean families and the various ways that parents may support their growing autonomy that is socially constructive. PMID- 30298044 TI - Theory of Mind Development in School-Aged Left-Behind Children in Rural China. AB - The current study aimed to investigate differences in theory of mind between left behind children and non-left-behind children in rural China and to examine the potential protective role of general reasoning ability in left-behind children's theory of mind. Participants included 213 children aged 7.10-13.67 years (111 boys and 102 girls, M = 10.51 years, SD = 1.33), 101 of whom were left behind in rural areas by one or both migrating parents for at least 6 months. The Strange Stories task, a second-order false belief task, and a faux pas task were used to measure children's theory of mind, and Sessions B and C in Raven's Standard Progressive Matrices were used to test children's general reasoning ability. The results showed that left-behind children scored lower on both the faux pas task and Strange Stories task. Additionally, on second-order false belief understanding, left-behind boys performed worse than non-left-behind boys, while left-behind girls scored higher than non-left behind girls. Moreover, children's general reasoning ability moderated the relationship between parental migrant status and children's faux pas understanding: For children with high levels of general reasoning ability, left-behind children performed similarly to non-left behind children, while for children with low levels of general reasoning ability, left-behind children scored lower than non-left-behind children, indicating that general reasoning ability buffered the negative effect of being left behind on children's theory of mind development. The implications of these findings for training directed at left-behind children are discussed. PMID- 30298046 TI - Palinopsia Following Acute Unilateral Partial Vestibular Deafferentation: A Case Report. AB - Palinopsia is defined as the persistence or reappearance of images after cessation of the visual stimulus. One patient presented episodes of palinopsia after the functional loss of the 3 semicircular canals of the right ear while the otolithic function was preserved. None of classical causes was identified in this patient, intoxications, brain tumors, migraines, psychiatric disorders, etc. For a movement to be perceived as a single event, central processes of temporal integration are necessary to correct the shift between the rapid vestibular information, and the slow visual information. However, it has been shown on animal models that vestibular inputs are slower than normal in case of peripheral deafferentation limited to the canalar function with preservation of the otolithic function, which is the case in this patient. Therefore, we hypothesize that episodes of palinopsia he presents result from the fact that temporal integration processes do not take into account the slower than normal vestibular information due to the peripheral disorder and continue to slow it down. Thus, the patient keeps the visual image in memory until the late arrival of the vestibular information. PMID- 30298045 TI - Neuropsychological and Psychological Functioning Aspects in Myotonic Dystrophy Type 1 Patients in Italy. AB - Introduction: Myotonic Dystrophy Type 1 (DM1) is an autosomal dominant genetic illness, characterized by a progressive loss of strength. Important deficits in cognitive functioning and a significant prevalence of psychiatric disorders have been previously reported. Methods:A neuropsychological and psychological assessment was carried out in 31 DM1 patients (61% males) in order to measure the cognitive functioning and explore their personality profiles. The MMSE Mini Mental State Examination, Frontal Assessment Battery (FAB), ENB-2 Battery assessing memory (short term, long term and working memory), integration capacities, visual-spatial ability, attention (selective, divided, shifting/switching) executive functions, praxis, discrimination and logic capabilities and psychopathology Symptom Check List 90-R (SCL-90-R) were administered. The neuropsychological and psychological evaluation of DM1 patients was carried out taking into consideration the clinical parameters (CTG repeat, age at onset, disease duration, Muscular Impairment Rate Scale (MIRS), Medical Research Council Scale (MRC) and the Epworth Sleepiness Scales (EPS)). Results: Regarding psychopathology 19.4% of patients scored a moderate or high level of symptoms intensity index (GSI), 12.9% reported a high number of symptoms (PST) and 16.1% reported a high intensity level of the perceived symptoms (PSDI). Fatigue and daytime sleepiness resulted as being associated with higher levels of psychoticism (PSY). Only 1 patient reported a severe impairment in the spatial and temporal orientation, memory, language, praxis, attention and calculation. Longer disease duration was also associated with cognitive impairment evaluated through ENB-2 (p < 0.05). Discussions and Conclusions:There are indications of the utility of neuropsychological and psychological screening and support for these patients and their families due to the link between disease duration and cognitive performances. A proposal of a clinical protocol, with an illustration of a clinical case report of a family is presented. PMID- 30298047 TI - Differentiation of Brain Metastases and Gliomas Based on Color Map of Phase Difference Enhanced Imaging. AB - Background and objective: Phase difference enhanced imaging (PADRE), a new phase related MRI technique, can enhance both paramagnetic and diamagnetic substances, and select which phases to be enhanced. Utilizing these characteristics, we developed color map of PADRE (Color PADRE), which enables simultaneous visualization of myelin-rich structures and veins. Our aim was to determine whether Color PADRE is sufficient to delineate the characteristics of non gadolinium-enhancing T2-hyperintense regions related with metastatic tumors (MTs), diffuse astrocytomas (DAs) and glioblastomas (GBs), and whether it can contribute to the differentiation of MTs from GBs. Methods: Color PADRE images of 11 patients with MTs, nine with DAs and 17 with GBs were created by combining tissue-enhanced, vessel-enhanced and magnitude images of PADRE, and then retrospectively reviewed. First, predominant visibility of superficial white matter and deep medullary veins within non-gadolinium-enhancing T2-hyperintense regions were compared among the three groups. Then, the discriminatory power to differentiate MTs from GBs was assessed using receiver operating characteristic analysis. Results: The degree of visibility of superficial white matter was significantly better in MTs than in GBs (p = 0.017), better in GBs than in DAs (p = 0.014), and better in MTs than in DAs (p = 0.0021). On the contrary, the difference in the visibility of deep medullary veins was not significant (p = 0.065). The area under the receiver operating characteristic curve to discriminate MTs from GBs was 0.76 with a sensitivity of 80% and specificity of 64%. Conclusion: Visibility of superficial white matter on Color PADRE reflects inferred differences in the proportion of vasogenic edema and tumoral infiltration within non-gadolinium-enhancing T2-hyperintense regions of MTs, DAs and GBs. Evaluation of peritumoral areas on Color PADRE can help to distinguish MTs from GBs. PMID- 30298048 TI - New Insights on Emotional Contributions to Human Postural Control. AB - It has been just over 20 years since the effects of height-induced threat on human postural control were first investigated. Raising the height of the support surface on which individuals stood increased the perceived consequences of instability and generated postural control changes. Since this initial work, converging evidence has accumulated supporting the efficacy of using height induced threat to study the effects of emotions on postural control and confirming a direct influence of threat-related changes in arousal, anxiety, and fear of falling on all aspects of postural control, including standing, anticipatory, and reactive balance. In general, threat-related postural changes promote a greater physical safety margin while maintaining upright stance. We use the static balance literature to critically examine the current state of knowledge regarding: (1) the extent to which threat-related changes in postural control are sensitive to threat-related changes in emotions; (2) the underlying neurophysiological and cognitive mechanisms that may contribute to explaining the relationship between emotions and postural control; and (3) the generalizability of threat-related changes across different populations and types of threat. These findings have important implications for understanding the neuromechanisms that control healthy balance, and highlight the need to recognize the potential contributions of psychological and physiological factors to balance deficits associated with age or pathology. We conclude with a discussion of the practical significance of this research, its impact on improving diagnosis and treatment of postural control deficits, and potential directions for future research. PMID- 30298049 TI - HIV-1-Associated Neurocognitive Disorders: Is HLA-C Binding Stability to beta2 Microglobulin a Missing Piece of the Pathogenetic Puzzle? AB - AIDS dementia complex (ADC) and HIV-associated neurocognitive disorders (HAND) are complications of HIV-1 infection. Viral infections are risk factors for the development of neurodegenerative disorders. Aging is associated with low-grade inflammation in the brain, i.e., the inflammaging. The molecular mechanisms linking immunosenescence, inflammaging and the pathogenesis of neurodegenerative disorders, such as Alzheimer's disease (AD) and Parkinson's disease, are largely unknown. ADC and HAND share some pathological features with AD and may offer some hints on the relationship between viral infections, neuroinflammation, and neurodegeneration. beta2-microglobulin (beta2m) is an important pro-aging factor that interferes with neurogenesis and worsens cognitive functions. Several studies published in the 80-90s reported high levels of beta2m in the cerebrospinal fluid of patients with ADC. High levels of beta2m have also been detected in AD. Inflammatory diseases in elderly people are associated with polymorphisms of the MHC-I locus encoding HLA molecules that, by associating with beta2m, contribute to cellular immunity. We recently reported that HLA-C, no longer associated with beta2m, is incorporated into HIV-1 virions, determining an increase in viral infectivity. We also documented the presence of HLA-C variants more or less stably linked to beta2m. These observations led us to hypothesize that some variants of HLA-C, in the presence of viral infections, could determine a greater release and accumulation of beta2m, which in turn, may be involved in triggering and/or sustaining neuroinflammation. ADC is the most severe form of HAND. To explore the role of HLA-C in ADC pathogenesis, we analyzed the frequency of HLA-C variants with unstable binding to beta2m in a group of patients with ADC. We found a higher frequency of unstable HLA-C alleles in ADC patients, and none of them was harboring stable HLA-C alleles in homozygosis. Our data suggest that the role of HLA-C variants in ADC/HAND pathogenesis deserves further studies. If confirmed in a larger number of samples, this finding may have practical implication for a personalized medicine approach and for developing new therapies to prevent HAND. The exploration of HLA-C variants as risk factors for AD and other neurodegenerative disorders may be a promising field of study. PMID- 30298050 TI - 3-Iodothyronamine Activates a Set of Membrane Proteins in Murine Hypothalamic Cell Lines. AB - 3-Iodothyronamine (3-T1AM) is an endogenous thyroid hormone metabolite. The profound pharmacological effects of 3-T1AM on energy metabolism and thermal homeostasis have raised interest to elucidate its signaling properties in tissues that pertain to metabolic regulation and thermogenesis. Previous studies identified G protein-coupled receptors (GPCRs) and transient receptor potential channels (TRPs) as targets of 3-T1AM in different cell types. These two superfamilies of membrane proteins are largely expressed in tissue which influences energy balance and metabolism. As the first indication that 3-T1AM virtually modulates the function of the neurons in hypothalamus, we observed that intraperitoneal administration of 50 mg/kg bodyweight of 3-T1AM significantly increased the c-FOS activation in the paraventricular nucleus (PVN) of C57BL/6 mice. To elucidate the underlying mechanism behind this 3-T1AM-induced signalosome, we used three different murine hypothalamic cell lines, which are all known to express PVN markers, GT1-7, mHypoE-N39 (N39) and mHypoE-N41 (N41). Various aminergic GPCRs, which are the known targets of 3-T1AM, as well as numerous members of TRP channel superfamily, are expressed in these cell lines. Effects of 3-T1AM on activation of GPCRs were tested for the two major signaling pathways, the action of Galphas/adenylyl cyclase and Gi/o. Here, we demonstrated that this thyroid hormone metabolite has no significant effect on Gi/o signaling and only a minor effect on the Galphas/adenylyl cyclase pathway, despite the expression of known GPCR targets of 3-T1AM. Next, to test for other potential mechanisms involved in 3-T1AM-induced c-FOS activation in PVN, we evaluated the effect of 3-T1AM on the intracellular Ca2+ concentration and whole-cell currents. The fluorescence-optic measurements showed a significant increase of intracellular Ca2+ concentration in the three cell lines in the presence of 10 MUM 3-T1AM. Furthermore, this thyroid hormone metabolite led to an increase of whole-cell currents in N41 cells. Interestingly, the TRPM8 selective inhibitor (10 MUM AMTB) reduced the 3-T1AM stimulatory effects on cytosolic Ca2+ and whole cell currents. Our results suggest that the profound pharmacological effects of 3 T1AM on selected brain nuclei of murine hypothalamus, which are known to be involved in energy metabolism and thermoregulation, might be partially attributable to TRP channel activation in hypothalamic cells. PMID- 30298051 TI - Exosomes Derived From Mesenchymal Stromal Cells Pretreated With Advanced Glycation End Product-Bovine Serum Albumin Inhibit Calcification of Vascular Smooth Muscle Cells. AB - Background: The osteogenic differentiation of vascular smooth muscle cell (VSMCs) is important for the development of vascular calcification (VC), particularly in diabetes. Exosomes derived from Mesenchymal Stromal Cells (MSCs) are effective against cardiovascular diseases, yet their role in VC remains unclear. Advanced glycation end products (AGEs) inhibit bone marrow stromal cell osteogenesis by targeting osteogenesis-associated genes. Thus, we investigated the role of exosomes derived from MSCs pretreated with AGEs-BSA in VC and its potential mechanisms. Methods: Primary VSMCs and MSCs were isolated from the aorta and bone marrow of Sprague-Dawley rats, respectively. VSMCs were cultured with AGEs-BSA to induce osteogenic differentiation. Exosomes were harvested from MSCs by ultracentrifugation. MSCs and VSMCs were cocultured in Transwells, and exosomes were added to VSMC culture medium to assess their effects on osteogenic differentiation. Double luciferase reporter assay was applied to confirm that miR 146a directly targets the 3' UTR of the thioredoxin-interacting protein (TXNIP) gene. Results: Pretreatment of VSMCs with AGEs-BSA increased the expression of thioredoxin-interacting protein (TXNIP) by inhibiting that of miR-146a, resulting in enhanced ROS production and VSMC calcification. By contrast, the expression of miR-146a in MSCs was increased by AGEs-BSA treatment. Thus, miR-146a was transferred from AGEs-BSA-pretreated or miR-146a-transfected MSCs to VSMCs via exosomes. After coculture with miR-146a-containing exosomes, the AGEs-BSA mediated increase in VSMC calcification was diminished, accompanied by decreased TXNIP expression and ROS production. Furthermore, TXNIP overexpression counteracted the anti-calcification effects of MSC-derived miR-146a-containing exosomes. In addition, TXNIP was identified as a target gene of miR-146a, and the results of double luciferase reporter assay confirmed that TXNIP was the direct target gene of miR-146a. Conclusions: Exosomes secreted by MSCs pretreated with AGEs-BSA contained a high level of miR-146a, which was transferred to VSMCs and inhibited AGEs-BSA-induced calcification in a TXNIP-dependent manner. Thus, miR 146a-containing exosomes may be a potential therapeutic target for VC. PMID- 30298052 TI - The Antidiabetic Drug Lobeglitazone Protects Mice From Lipogenesis-Induced Liver Injury via Mechanistic Target of Rapamycin Complex 1 Inhibition. AB - Non-alcoholic fatty liver disease (NAFLD) is a metabolic disorder closely linked with type II diabetes (T2D). The progression of NAFLD is associated with the induction of lipogenesis through hyperactivation of the mechanistic target of rapamycin complex 1 (mTORC1) pathway. An increase in lipogenesis induces endoplasmic reticulum (ER) stress and accelerates oxidative liver injury in the pathogenesis of NAFLD. Lobeglitazone, one of thiazolidinediones (TZDs), is used as an antidiabetic drug to lower serum glucose level through an increase in insulin sensitivity. It is known to improve pathological symptoms in animals and humans with NAFLD. However, the underlying molecular mechanism of the protective effects of lobeglitazone against NAFLD has not been elucidated. Here, we show that under the physiological condition of acute lipogenesis, lobeglitazone inhibits hepatic lipid synthesis, the subsequent ER stress, and omega-oxidation of fatty acids by inhibiting the mTORC1 pathway. As a result, lobeglitazone protected mice from lipogenesis-induced oxidative liver injury. Taken together, lobeglitazone might be a suitable drug for the treatment of patients with diabetes and NAFLD. PMID- 30298053 TI - Excessive Neutrophil Activity in Gestational Diabetes Mellitus: Could It Contribute to the Development of Preeclampsia? AB - Gestational diabetes mellitus is a transient form of glucose intolerance occurring during pregnancy. Pregnancies affected by gestational diabetes mellitus are at risk for the development of preeclampsia, a severe life threatening condition, associated with significant feto-maternal morbidity and mortality. It is a risk factor for long-term health in women and their offspring. Pregnancy has been shown to be associated with a subliminal degree of neutrophil activation and tightly regulated generation of neutrophil extracellular traps (NETs). This response is excessive in cases with preeclampsia, leading to the presence of large numbers of NETs in affected placentae. We have recently observed that circulatory neutrophils in cases with gestational diabetes mellitus similarly exhibit an excessive pro-NETotic phenotype, and pronounced placental presence, as detected by expression of neutrophil elastase. Furthermore, exogenous neutrophil elastase liberated by degranulating neutrophils was demonstrated to alter trophoblast physiology and glucose metabolism by interfering with key signal transduction components. In this review we examine whether additional evidence exists suggesting that altered neutrophil activity in gestational diabetes mellitus may contribute to the development of preeclampsia. PMID- 30298056 TI - In silico Prediction and Exploration of Potential Bacteriocin Gene Clusters Within the Bacterial Genus Geobacillus. AB - The thermophilic, endospore-forming genus of Geobacillus has historically been associated with spoilage of canned food. However, in recent years it has become the subject of much attention due its biotechnological potential in areas such as enzyme and biofuel applications. One aspect of this genus that has not been fully explored or realized is its use as a source of novel forms of the ribosomally synthesized antimicrobial peptides known as bacteriocins. To date only two bacteriocins have been fully characterized within this genus, i.e., Geobacillin I and II, with only a small number of others partially characterized. Here we bioinformatically investigate the potential of this genus as a source of novel bacteriocins through the use of the in silico screening software BAGEL3, which scans publically available genomes for potential bacteriocin gene clusters. In this study we examined the association of bacteriocin gene presence with niche and phylogenetic position within the genus. We also identified a number of candidates from multiple bacteriocin classes which may be promising antimicrobial candidates when investigated in vitro in future studies. PMID- 30298054 TI - Antibiotics, Resistome and Resistance Mechanisms: A Bacterial Perspective. AB - History of mankind is regarded as struggle against infectious diseases. Rather than observing the withering away of bacterial diseases, antibiotic resistance has emerged as a serious global health concern. Medium of antibiotic resistance in bacteria varies greatly and comprises of target protection, target substitution, antibiotic detoxification and block of intracellular antibiotic accumulation. Further aggravation to prevailing situation arose on observing bacteria gradually becoming resistant to different classes of antibiotics through acquisition of resistance genes from same and different genera of bacteria. Attributing bacteria with feature of better adaptability, dispersal of antibiotic resistance genes to minimize effects of antibiotics by various means including horizontal gene transfer (conjugation, transformation, and transduction), Mobile genetic elements (plasmids, transposons, insertion sequences, integrons, and integrative-conjugative elements) and bacterial toxin-antitoxin system led to speedy bloom of antibiotic resistance amongst bacteria. Proficiency of bacteria to obtain resistance genes generated an unpleasant situation; a grave, but a lot unacknowledged, feature of resistance gene transfer. PMID- 30298055 TI - The Lactobacillus casei Group: History and Health Related Applications. AB - The Lactobacillus casei group (LCG), composed of the closely related Lactobacillus casei, Lactobacillus paracasei, and Lactobacillus rhamnosus are some of the most widely researched and applied probiotic species of lactobacilli. The three species have been extensively studied, classified and reclassified due to their health promoting properties. Differentiation is often difficult by conventional phenotypic and genotypic methods and therefore new methods are being continually developed to distinguish the three closely related species. The group remain of interest as probiotics, and their use is widespread in industry. Much research has focused in recent years on their application for health promotion in treatment or prevention of a number of diseases and disorders. The LCG have the potential to be used prophylactically or therapeutically in diseases associated with a disturbance to the gut microbiota. The group have been extensively researched with regard to stress responses, which are crucial for their survival and therefore application as probiotics. PMID- 30298057 TI - Pathogenicity Induced by Invasive Infection of Streptococcus dysgalactiae subsp. equisimilis in a Mouse Model of Diabetes. AB - Streptococcus dysgalactiae subsp. equisimilis (SDSE) causes severe invasive diseases such as streptococcal toxic shock syndrome, similar to that caused by S. pyogenes (GAS). Invasive SDSE infections are increasing, particularly among patients with diabetes mellitus. Here we investigate the association between the pathogenicity of SDSE and diabetes mellitus in a mouse model, using GAS infection for comparison. Intraperitoneal injection of highly hemolytic SDSE-167 into C57BL6/J mice induced a rapid rise in blood glucose concentrations within 4 h, which was otherwise seen only in mice injected with high doses of hypervirulent GAS mutants. The survival rates of mice injected with SDSE-167 were significantly lower in mice (db/db) with type 2 diabetes than in nondiabetic mice. Injection of db/db mice with SDSE-167 increased the concentrations of cytokines and chemokines, particularly those of interleukin 6 and monocyte chemotactic protein 1. Microarray data indicate that multiple pathways are involved in the pathogenicity of SDSE-167 in db/db mice. These data reveal that the mechanisms underlying streptococcal infection differ between SDSE and GAS. PMID- 30298058 TI - Isolation and Transcriptome Analysis of Phenol-Degrading Bacterium From Carbon Sand Filters in a Full-Scale Drinking Water Treatment Plant. AB - Phenol is a typical organic contaminant in the environment. To date, the biodegradation of phenol by microorganisms remains the preferred method for its removal and remediation, but data on phenol removal by drinking water biofilters are lacking. In this study, we used high-throughput sequencing to investigate the microbial community structure in a carbon-sand biofilter. The results indicated that the predominant bacterial group was Bacilli, followed by Gammaproteobacteria, Clostridia, and Alphaproteobacteria. In addition, a strain was capable of degrading phenol at low concentrations of 500 MUg/L within 100 min was isolated and identified as Rhodococcus sp. CS-1. Transcriptome analysis results showed that Rhodococcus sp. CS-1 was able to degrade phenol via both the catechol and protocatechuate branch of the beta-ketoadipate pathway. Furthermore, some novel candidate biomarkers (copper oxidase, copper chaperone, and MarR/DeoR/TetR family transcriptional regulators) were successfully identified to be potentially involved in phenol biodegradation. This study indicates that carbon-sand filters have the potential for remediation of phenol. The application of native microorganisms to drinking water treatment system is an adaptive strategy in oligotrophic water environments. PMID- 30298059 TI - Metabolic Engineering of Yeast for the Production of 3-Hydroxypropionic Acid. AB - The beta-hydroxy acid 3-hydroxypropionic acid (3-HP) is an attractive platform compound that can be used as a precursor for many commercially interesting compounds. In order to reduce the dependence on petroleum and follow sustainable development, 3-HP has been produced biologically from glucose or glycerol. It is reported that 3-HP synthesis pathways can be constructed in microbes such as Escherichia coli, Klebsiella pneumoniae and the yeast Saccharomyces cerevisiae. Among these host strains, yeast is prominent because of its strong acid tolerance which can simplify the fermentation process. Currently, the malonyl-CoA reductase pathway and the beta-alanine pathway have been successfully constructed in yeast. This review presents the current developments in 3-HP production using yeast as an industrial host. By combining genome-scale engineering tools, malonyl-CoA biosensors and optimization of downstream fermentation, the production of 3-HP in yeast has the potential to reach or even exceed the yield of chemical production in the future. PMID- 30298060 TI - Naturally Fermented Milk From Northern Senegal: Bacterial Community Composition and Probiotic Enrichment With Lactobacillus rhamnosus. AB - A variety of foods fermented with lactic acid bacteria serve as dietary staples in many African communities; yet, their bacterial profiles are poorly characterized. The integration of health-promoting probiotics into naturally fermented milk products could make a profound impact on human health. Here, we characterize the bacterial community composition of a naturally fermented milk product (lait caille) from northern Senegal, prepared in wooden bowls (lahals) with a bacterial biofilm to steer the fermentation process. We incorporated a probiotic starter culture containing the most documented probiotic strain Lactobacillus rhamnosus GG (generic strain name yoba 2012) into the local fermentation process. Bar-coded 16S rRNA amplicon sequencing of lait caille samples indicated that the bacterial community of lait caille has high species richness with over 100 bacterial genera; however, few have high abundance. In contrast to the diverse bacterial compositions of other characterized naturally fermented milk products, the composition of lait caille predominantly consists of the lactic acid bacteria Streptococcus and Lactobacillus, resembling the bacterial composition in regular yogurt. The bacterial community composition of lait caille varies geographically based on the presence of some genera, including Lactoccoccus, Enterococcus, Bifidobacterium, and Bacillus, but this trend is not consistent within production communities. The diversity of bacterial communities is much higher in the lahal biofilm than in the naturally fermented milk products, which is in turn greater than in commercial yogurts. Addition of a starter culture with L. rhamnosus yoba 2012 to milk in lahals led to substantial growth of this probiotic bacterium during the fermentation process. Two independent quantitative PCR-analyses specific for L. rhamnosus yoba 2012 indicated a 20- to 60-fold increase in the total number of probiotic bacteria in the first batch after inoculation. A similar increase of the probiotic was observed in a variation of lait caille prepared with carbohydrate-rich millet granules (thiakry) added prior to fermentation. This study shows the feasibility of integrating health-promoting probiotic strains into naturally fermented foods produced in regions with a high prevalence of malnutrition. PMID- 30298061 TI - Microbial Changes and Host Response in F344 Rat Colon Depending on Sex and Age Following a High-Fat Diet. AB - Gut microbiota, an important component that affects host health, change rapidly and directly in response to altered diet composition. Recently, the role of diet microbiome interaction on the development of colon cancer has been the focus of interest. Colon cancer occurs more frequently in an aged population, and in males. However, the effect of dietary changes on the gut microbiome has been studied mainly in young males, even though it may vary with age and sex. The aim of this study was to investigate microbial changes and host response in the colons of male and female 6-week-old (young) and 2-year-old (old) Fisher-344 rats exposed to a high-fat diet (HFD). Our results showed that exposure to HFD for 8 weeks decreased the species richness of microbiota (Chao1) and increased Firmicutes/Bacteroidetes ratio only in aged rats, and not in young rats. Sex differences underlying the alteration by HFD in the gut microbiome were observed in the microbiome of aged rats. For instance, the abundance ratio of Akkermansia muciniphila and Desulfovibrio spp. increased in response to HFD in young rats and female aged rats, but not in male aged rats. Histological inflammation and cell proliferation of colon mucosa (indexed by Ki67) were significantly increased by HFD even in young rats; aged rats showed significantly higher cell proliferation in the HFD group than in the control. The HFD-induced decrease of species richness and the increase in specific species (Desulfovibrio spp. and Clostridium lavalense), which produce carcinogenic compounds such as H2S and N-nitroso compounds, were significantly correlated with Ki67 index. In colon mucosa, the concentration of myeloperoxidase was increased by HFD only in males, and not in females. In conclusion, the results suggest a link between HFD-induced gut dysbiosis (particularly the low species richness and high abundance ratios of Desulfovibrio spp. and C. lavalense) and cell proliferation of colon mucosa (indicated by Ki67 IHC). In addition, sex differences influence the response of gut microbiome to HFD particularly in old age. Such sex differences in the gut microbiota might be related to sex differences in inflammation in the colon mucosa. PMID- 30298062 TI - MK2 Regulates Macrophage Chemokine Activity and Recruitment to Promote Colon Tumor Growth. AB - A major risk factor for colon cancer growth and progression is chronic inflammation. We have shown that the MAPK-activated protein kinase 2 (MK2) pathway is critical for colon tumor growth in colitis-associated and spontaneous colon cancer models. This pathway is known to regulate expression of the tumor promoting cytokines, IL-1, IL-6, and TNF-alpha. However, little is known about the ability of MK2 to regulate chemokine production. This is the first study to demonstrate this pathway also regulates the chemokines, MCP-1, Mip-1alpha, and Mip-2alpha (MMM). We show that these chemokines induce tumor cell growth and invasion in vitro and that MK2 inhibition suppresses tumor cell production of chemokines and reverses the resulting pro-tumorigenic effects. Addition of MMM to colon tumors in vivo significantly enhances tumor growth in control tumors and restores tumor growth in the presence of MK2 inhibition. We also demonstrate that MK2 signaling is critical for chemokine expression and macrophage influx to the colon tumor microenvironment. MK2 signaling in macrophages was essential for inflammatory cytokine/chemokine production, whereas MK2-/- macrophages or MK2 inhibition suppressed cytokine expression. We show that addition of bone marrow derived macrophages to the tumor microenvironment enhances tumor growth in control tumors and restores tumor growth in tumors treated with MK2 inhibitors, while addition of MK2-/- macrophages had no effect. This is the first study to demonstrate the critical role of the MK2 pathway in chemokine production, macrophage influx, macrophage function, and tumor growth. PMID- 30298065 TI - Eliciting Dose and Safety Outcomes From a Large Dataset of Standardized Multiple Food Challenges. AB - Background: Food allergy prevalence has continued to rise over the past decade. While studies have reported threshold doses for multiple foods, large-scale multi food allergen studies are lacking. Our goal was to identify threshold dose distributions and predictors of severe reactions during blinded oral food challenges (OFCs) in multi-food allergic patients. Methods: A retrospective chart review was performed on all Stanford-initiated clinical protocols involving standardized screening OFCs to any of 11 food allergens at 7 sites. Interval censoring survival analysis was used to calculate eliciting dose (ED) curves for each food. Changes in severity and ED were also analyzed among participants who had repeated challenges to the same food. Results: Of 428 participants, 410 (96%) had at least one positive challenge (1445 standardized OFCs with 1054 total positive challenges). Participants undergoing peanut challenges had the highest ED50 (29.9 mg), while those challenged with egg or pistachio had the lowest (7.07 or 1.7 mg, respectively). The most common adverse event was skin related (54%), followed by gastrointestinal (GI) events (33%). A history of asthma was associated with a significantly higher risk of a severe reaction (hazard ratio [HR]: 2.37, 95% confidence interval [CI]: 1.36, 4.13). Higher values of allergen specific IgE (sIgE) and sIgE to total IgE ratio (sIgEr) were also associated with higher risk of a severe reaction (1.49 [1.19, 1.85] and 1.84 [1.30, 2.59], respectively). Participants undergoing cashew, peanut, pecan, sesame, and walnut challenges had more severe reactions as ED increased. In participants who underwent repeat challenges, the ED did not change (p = 0.66), but reactions were more severe (p = 0.02). Conclusions: Participants with a history of asthma, high sIgEr, and/or high values of sIgE were found to be at higher risk for severe reactions during food challenges. These findings may help to optimize food challenge dosing schemes in multi-food allergic, atopic patients, specifically at lower doses where the majority of reactions occur. Trials Registration Number: ClinicalTrials. gov number NCT03539692; https://clinicaltrials.gov/ct2/show/NCT03539692. PMID- 30298063 TI - Positive & Negative Roles of Innate Effector Cells in Controlling Cancer Progression. AB - Innate immune cells are active at the front line of host defense against pathogens and now appear to play a range of roles under non-infectious conditions as well, most notably in cancer. Establishing the balance of innate immune responses is critical for the "flavor" of these responses and subsequent adaptive immunity and can be either "good or bad" in controlling cancer progression. The importance of innate NK cells in tumor immune responses has already been extensively studied over the last few decades, but more recently several relatively mono- or oligo-clonal [i.e., (semi-) invariant] innate T cell subsets received substantial interest in tumor immunology including invariant natural killer T (iNKT), gammadelta-T and mucosal associated invariant T (MAIT) cells. These subsets produce high levels of various pro- and/or anti-inflammatory cytokines/chemokines reflecting their capacity to suppress or stimulate immune responses. Survival of patients with cancer has been linked to the frequencies and activation status of NK, iNKT, and gammadelta-T cells. It has become clear that NK, iNKT, gammadelta-T as well as MAIT cells all have physiological roles in anti-tumor responses, which emphasize their possible relevance for tumor immunotherapy. A variety of clinical trials has focused on manipulating NK, iNKT, and gammadelta-T cell functions as a cancer immunotherapeutic approach demonstrating their safety and potential for achieving beneficial therapeutic effects, while the exploration of MAIT cell related therapies is still in its infancy. Current issues limiting the full therapeutic potential of these innate cell subsets appear to be related to defects and suppressive properties of these subsets that, with the right stimulus, might be reversed. In general, how innate lymphocytes are activated appears to control their subsequent abilities and consequent impact on adaptive immunity. Controlling these potent regulators and mediators of the immune system should enable their protective roles to dominate and their deleterious potential (in the specific context of cancer) to be mitigated.

AB - Background: Among the many cannabinoids in the cannabis plant, cannabidiol (CBD) is a compound that does not produce the typical subjective effects of marijuana. Objectives: The aim of the present review is to describe the main advances in the development of the experimental and clinical use of cannabidiol CBD in neuropsychiatry. Methods: A non-systematic search was performed for studies dealing with therapeutic applications of CBD, especially performed by Brazilian researchers. Results: CBD was shown to have anxiolytic, antipsychotic and neuroprotective properties. In addition, basic and clinical investigations on the effects of CBD have been carried out in the context of many other health conditions, including its potential use in epilepsy, substance abuse and dependence, schizophrenia, social phobia, post-traumatic stress, depression, bipolar disorder, sleep disorders, and Parkinson. Discussion: CBD is an useful and promising molecule that may help patients with a number of clinical conditions. Controlled clinical trials with different neuropsychiatric populations that are currently under investigation should bring important answers in the near future and support the translation of research findings to clinical settings. PMID- 30298067 TI - Oncolytic Viruses Partner With T-Cell Therapy for Solid Tumor Treatment. AB - Adoptive T-cell immunotherapies, including chimeric antigen receptor-modified T cells (CAR-T cells), have revolutionized cancer treatment, especially for hematologic malignancies. Clinical success of CAR-T cell monotherapy in solid tumors however, has been only modest. Oncolytic viruses provide direct cancer cell lysis, stimulate systemic immune responses, and have the capacity to provide therapeutic transgenes. Oncolytic virotherapy has shown great promise in many preclinical solid tumor models and the first oncolytic virus has been approved by the FDA for the treatment of advanced melanoma. As monotherapies for solid tumors, oncolytic virotherapy provides only moderate anti-tumor effects. However, due to their complementary modes of action, oncolytic virus and T-cell therapies can be combined to overcome the inherent limitations of each agent. This review focuses on the aspects of oncolytic viruses that enable them to synergize with adoptive T-cell immunotherapies to enhance anti-tumor effects for solid tumors. PMID- 30298066 TI - Searching for the Transcriptomic Signature of Immune Tolerance Induction Biomarkers of Safety and Functionality for Tolerogenic Dendritic Cells and Regulatory Macrophages. AB - The last years have witnessed a breakthrough in the development of cell-based tolerance-inducing cell therapies for the treatment of autoimmune diseases and solid-organ transplantation. Indeed, the use of tolerogenic dendritic cells (tolDC) and regulatory macrophages (Mreg) is currently being tested in Phase I and Phase II clinical trials worldwide, with the aim of finding an effective therapy able to abrogate the inflammatory processes causing these pathologies without compromising the protective immunity of the patients. However, there exists a wide variety of different protocols to generate human tolDC and Mreg and, consequently, the characteristics of each product are heterogeneous. For this reason, the identification of biomarkers able to define their functionality (tolerogenicity) is of great relevance, on the one hand, to guarantee the safety of tolDC and Mreg before administration and, on the other hand, to compare the results between different cell products and laboratories. In this article, we perform an exhaustive review of protocols generating human tolDC and Mreg in the literature, aiming to elucidate if there are any common transcriptomic signature or potential biomarkers of tolerogenicity among the different approaches. However, and although several effectors seem to be induced in common in some of the most reported protocols to generate both tolDC or Mreg, the transcriptomic profile of these cellular products strongly varies depending on the approach used to generate them. PMID- 30298069 TI - ImmuneDB, a Novel Tool for the Analysis, Storage, and Dissemination of Immune Repertoire Sequencing Data. AB - ImmuneDB is a system for storing and analyzing high-throughput immune receptor sequencing data. Unlike most existing tools, which utilize flat-files, ImmuneDB stores data in a well-structured MySQL database, enabling efficient data queries. It can take raw sequencing data as input and annotate receptor gene usage, infer clonotypes, aggregate results, and run common downstream analyses such as calculating selection pressure and constructing clonal lineages. Alternatively, pre-annotated data can be imported and analyzed data can be exported in a variety of common Adaptive Immune Receptor Repertoire (AIRR) file formats. To validate ImmuneDB, we compare its results to those of another pipeline, MiXCR. We show that the biological conclusions drawn would be similar with either tool, while ImmuneDB provides the additional benefits of integrating other common tools and storing data in a database. ImmuneDB is freely available on GitHub at https://github.com/arosenfeld/immunedb, on PyPi at https://pypi.org/project/ImmuneDB, and a Docker container is provided at https://hub.docker.com/r/arosenfeld/immunedb.

PMID- 30298070 TI - Efficacy of Lactoferrin Oral Administration in the Treatment of Anemia and Anemia of Inflammation in Pregnant and Non-pregnant Women: An Interventional Study. AB - The discovery of the ferroportin-hepcidin complex has led to a critical review on the treatment of anemia and anemia of inflammation (AI). Ferroportin, the only known mammalian iron exporter from cells to blood, is negatively regulated by hepcidin, a hormone peptide able to bind to ferroportin, leading to its degradation. Therefore, new efficient therapeutic interventions acting on hepcidin and ferroportin are imperative to manage anemia and AI. Bovine milk derivative lactoferrin (bLf), a glycoprotein able to chelate two ferric ions per molecule, is emerging as a natural anti-inflammatory substance able to modulate hepcidin and ferroportin synthesis through the down-regulation of interleukin-6 (IL-6). Here, an interventional study (ClinicalTrials.gov Identifier: NCT01221844) was conducted by orally administering 100 mg of 20-30% iron saturated bLf (corresponding to 70-84 MUg of elemental iron) twice a day. This treatment was compared with the Italian standard therapy, consisting in the oral administration of 329.7 mg of ferrous sulfate once a day (corresponding to 105 mg of elemental iron). Treatments were carried out on 29 anemic women with minor beta-thalassemia (20 pregnant and 9 non-pregnant), 149 women with hereditary thrombophilia (HT) (70 pregnant and 79 non-pregnant) affected by AI and 20 anemic pregnant women suffering from various pathologies. In anemic pregnant and non pregnant women with minor beta-thalassemia, presenting undetectable hepcidin levels, differently from ferrous sulfate management, bLf decreased IL-6 (from 25 +/- 8 to 6 +/- 3 pg/ml) and increased total serum iron (TSI) (from 54 +/- 17 to 80 +/- 9 MUg/dl). BLf was also more efficient than ferrous sulfate in AI treatment in HT pregnant and non-pregnant women by decreasing both serum IL-6 (from 89 +/- 8 to 58 +/- 6 pg/ml) and hepcidin (from 115 +/- 23 to 65 +/- 10 ng/ml), thus increasing hematological parameters, such as the number of red blood cells (RBCs), the concentration of hemoglobin, TSI and serum ferritin. BLf was also efficient in treating anemia in other pathological pregnancies. Taken together all the results, bLf, showing a greater benefit and efficacy than the standard ferrous sulfate management, can be considered as a promising compound in treating anemia and AI through its ability to down-regulate IL-6, thus restoring ferroportin-mediated iron export from cells to blood in a hepcidin-dependent or independent way. PMID- 30298068 TI - Tissue-Resident Lymphocytes Across Innate and Adaptive Lineages. AB - Lymphocytes are an integral component of the immune system. Classically, all lymphocytes were thought to perpetually recirculate between secondary lymphoid organs and only traffic to non-lymphoid tissues upon activation. In recent years, a diverse family of non-circulating lymphocytes have been identified. These include innate lymphocytes, innate-like T cells and a subset of conventional T cells. Spanning the innate-adaptive spectrum, these tissue-resident lymphocytes carry out specialized functions and cross-talk with other immune cell types to maintain tissue integrity and homeostasis both at the steady state and during pathological conditions. In this review, we provide an overview of the heterogeneous tissue-resident lymphocyte populations, discuss their development, and highlight their functions both in the context of microbial infection and cancer. PMID- 30298072 TI - Prophylactic Treatment With Simvastatin Modulates the Immune Response and Increases Animal Survival Following Lethal Sepsis Infection. AB - Chronic use of statins may have anti-inflammatory action, promoting immunomodulation and survival in patients with sepsis. This study aimed to analyze the effects of pretreatment with simvastatin in lethal sepsis induced by cecal ligation and puncture (CLP). Male Swiss mice received prophylactic treatment with simvastatin or pyrogen-free water orally in a single daily dose for 30 days. After this period, the CLP was performed. Naive and Sham groups were performed as non-infected controls. Animal survival was monitored for 60 h after the CLP. Half of mice were euthanized after 12 h to analyze colony-forming units (CFUs); hematological parameters; production of IL-10, IL-12, IL-6, TNF-alpha, IFN-gamma, and MCP-1; cell counts on peritoneum, bronchoalveolar lavage (BAL), bone marrow, spleen, and mesenteric lymph node; immunephenotyping of T cells and antigen presenting cells and production of hydrogen peroxide (H2O2). Simvastatin induced an increase in survival and a decrease in the CFU count on peritoneum and on BAL cells number, especially lymphocytes. There was an increase in the platelets and lymphocytes number in the Simvastatin group when compared to the CLP group. Simvastatin induced a greater activation and proliferation of CD4+ T cells, as well as an increase in IL-6 and MCP-1 production, in chemotaxis to the peritoneum and in H2O2 secretion at this site. These data suggest that simvastatin has an impact on the survival of animals, as well as immunomodulatory effects in sepsis induced by CLP in mice. PMID- 30298071 TI - Host-Parasite Interactions Promote Disease Tolerance to Intestinal Helminth Infection. AB - Parasitic helminths are among the most pervasive pathogens of the animal kingdom. To complete their life cycle, these intestinal worms migrate through host tissues causing significant damage in their wake. As a result, infection can lead to malnutrition, anemia and increased susceptibility to co-infection. Despite repeated deworming treatment, individuals living in endemic regions remain highly susceptible to re-infection by helminths, but rarely succumb to excessive tissue damage. The chronicity of infection and inability to resist numerous species of parasitic helminths that have co-evolved with their hosts over millenia suggests that mammals have developed mechanisms to tolerate this infectious disease. Distinct from resistance where the goal is to destroy and eliminate the pathogen, disease tolerance is an active process whereby immune and structural cells restrict tissue damage to maintain host fitness without directly affecting pathogen burden. Although disease tolerance is evolutionary conserved and has been well-described in plant systems, only recently has this mode of host defense, in its strictest sense, begun to be explored in mammals. In this review, we will examine the inter- and intracellular networks that support disease tolerance during enteric stages of parasitic helminth infection and why this alternative host defense strategy may have evolved to endure the presence of non replicating pathogens and maintain the essential functions of the intestine. PMID- 30298073 TI - Leptin Elicits LTC4 Synthesis by Eosinophils Mediated by Sequential Two-Step Autocrine Activation of CCR3 and PGD2 Receptors. AB - Leptin is a cytokine, produced mainly by mature adipocytes, that regulates the central nervous system, mainly to suppress appetite and stimulate energy expenditure. Leptin also regulates the immune response by controlling activation of immunomodulatory cells, including eosinophils. While emerging as immune regulatory cells with roles in adipose tissue homeostasis, eosinophils have a well-established ability to synthesize pro-inflammatory molecules such as lipid mediators, a key event in several inflammatory pathologies. Here, we investigated the impact and mechanisms involved in leptin-driven activation of eicosanoid synthesizing machinery within eosinophils. Direct in vitro activation of human or mouse eosinophils with leptin elicited synthesis of lipoxygenase as well as cyclooxygenase products. Displaying selectivity, leptin triggered synthesis of LTC4 and PGD2, but not PGE2, in parallel to dose-dependent induction of lipid body/lipid droplets biogenesis. While dependent on PI3K activation, leptin-driven eosinophil activation was also sensitive to pertussis toxin, indicating the involvement of G-protein coupled receptors on leptin effects. Leptin-induced lipid body-driven LTC4 synthesis appeared to be mediated through autocrine activation of G-coupled CCR3 receptors by eosinophil-derived CCL5, inasmuch as leptin was able to trigger rapid CCL5 secretion, and neutralizing anti-RANTES or anti-CCR3 antibodies blocked lipid body assembly and LTC4 synthesis induced by leptin. Remarkably, autocrine activation of PGD2 G-coupled receptors DP1 and DP2 also contributes to leptin-elicited lipid body-driven LTC4 synthesis by eosinophils in a PGD2-dependent fashion. Blockade of leptin-induced PGD2 autocrine/paracrine activity by a specific synthesis inhibitor or DP1 and DP2 receptor antagonists, inhibited both lipid body biogenesis and LTC4 synthesis induced by leptin stimulation within eosinophils. In addition, CCL5-driven CCR3 activation appears to precede PGD2 receptor activation within eosinophils, since neutralizing anti-CCL5 or anti-CCR3 antibodies inhibited leptin-induced PGD2 secretion, while it failed to alter PGD2-induced LTC4 synthesis. Altogether, sequential activation of CCR3 and then PGD2 receptors by autocrine ligands in response to leptin stimulation of eosinophils culminates with eosinophil activation, characterized here by assembly of lipidic cytoplasmic platforms synthesis and secretion of the pleiotropic lipid mediators, PGD2, and LTC4. PMID- 30298074 TI - Genome-Wide Identification and Expression Profiling of the TCP Family Genes in Spike and Grain Development of Wheat (Triticum aestivum L.). AB - The TCP family genes are plant-specific transcription factors and play important roles in plant development. TCPs have been evolutionarily and functionally studied in several plants. Although common wheat (Triticum aestivum L.) is a major staple crop worldwide, no systematic analysis of TCPs in this important crop has been conducted. Here, we performed a genome-wide survey in wheat and found 66 TCP genes that belonged to 22 homoeologous groups. We then mapped these genes on wheat chromosomes and found that several TCP genes were duplicated in wheat including the ortholog of the maize TEOSINTE BRANCHED 1. Expression study using both RT-PCR and in situ hybridization assay showed that most wheat TCP genes were expressed throughout development of young spike and immature seed. Cis acting element survey along promoter regions suggests that subfunctionalization may have occurred for homoeologous genes. Moreover, protein-protein interaction experiments of three TCP proteins showed that they can form either homodimers or heterodimers. Finally, we characterized two TaTCP9 mutants from tetraploid wheat. Each of these two mutant lines contained a premature stop codon in the A subgenome homoeolog that was dominantly expressed over the B subgenome homoeolog. We observed that mutation caused increased spike and grain lengths. Together, our analysis of the wheat TCP gene family provides a start point for further functional study of these important transcription factors in wheat. PMID- 30298076 TI - Targeted Metabolic Profiling Indicates Apple Rootstock Genotype-Specific Differences in Primary and Secondary Metabolite Production and Validate Quantitative Contribution From Vegetative Growth. AB - Previous reports regarding rhizodeposits from apple roots are limited, and complicated by microbes, which readily colonize root systems and contribute to modify rhizodeposit metabolite composition. This study delineates methods for collection of apple rhizodeposits under axenic conditions, indicates rootstock genotype-specific differences and validates the contributions of vegetative activity to rhizodeposit quantity. Primary and phenolic rhizodeposit metabolites collected from two apple rootstock genotypes, G935 and M26, were delineated 2 months after root initiation by utilizing gas chromatography/liquid chromatography-mass spectrometry (GC/LC-MS), respectively. Twenty-one identified phenolic compounds and 29 sugars, organic acids, and amino acids, as well as compounds tentatively identified as triterpenoids were present in the rhizodeposits. When adjusted for whole plant mass, hexose, erythrose, galactose, phloridzin, kaempferol-3-glucoside, as well as glycerol, and glyceric acid differed between the genotypes. Phloridzin, phloretin, epicatechin, 4 hydroxybenzoic acid, and chlorogenic acid were among the phenolic compounds found in higher relative concentration in rhizodeposits, as assessed by LC-MS. Among primary metabolites assessed by GC-MS, amino acids, organic acids, and sugar alcohols found in relatively higher concentration in the rhizodeposits included L asparagine, L-cysteine, malic acid, succinic acid, and sorbitol. In addition, putative ursane triterprenoids, identified based on accurate mass comparison to previously reported triterpenoids from apple peel, were present in rhizodeposits in high abundance relative to phenolic compounds assessed via the same extraction/instrumental method. Validation of metabolite production to tree vegetative activity was conducted using a separate set of micropropagated trees (genotype MM106) which were treated with a toxic volatile compound (butyrolactone) to inhibit activity/kill leaves and vegetative growth. This treatment resulted in a reduction of total collected rhizodeposits relative to an untreated control, indicating active vegetative growth contributes to rhizodeposit metabolites. Culture-based assays indicated an absence of bacterial or fungal endophytes in roots of micropropagated G935 and M26 plants. However, the use of fungi-specific primers in qPCR indicated the presence of fungal DNA in 30% of the samples, thus the contribution of endophytes to rhizodeposits cannot be fully eliminated. This study provides fundamental information for continued research and application of rhizosphere ecology driven by apple rootstock genotype specific rhizodeposition. PMID- 30298075 TI - Usefulness of a New Large Set of High Throughput EST-SNP Markers as a Tool for Olive Germplasm Collection Management. AB - Germplasm collections are basic tools for conservation, characterization, and efficient use of olive genetic resources. The identification of the olive cultivars maintained in the collections is an important ongoing task which has been performed by both, morphological and molecular markers. In the present study, based on the sequencing results of previous genomic projects, a new set of 1,043 EST-SNP markers has been identified. In order to evaluate its discrimination capacity and utility in diversity studies, this set of markers was used in a representative number of accessions from 20 different olive growing countries and maintained at the World Olive Germplasm Collection of IFAPA Centre 'Alameda del Obispo' (Cordoba, Spain), one of the world's largest olive germplasm bank. Thus, the cultivated material included: cultivars belonging to previously defined core collections by means of SSR markers and agronomical traits, well known homonymy cases, possible redundancies previously identified in the collection, and recently introduced accessions. Marker stability was tested in repeated analyses of a selected number of accessions, as well as in different trees and accessions belonging to the same cultivar. In addition, 15 genotypes from a cross 'Picual' * 'Arbequina' cultivars from the IFAPA olive breeding program and a set of 89 wild genotypes were also included in the study. Our results indicate that, despite their relatively wide variability, the new set of EST-SNPs displayed lower levels of genetic diversity than SSRs in the set of olive core collections tested. However, the EST-SNP markers displayed consistent and reliable results from different plant material sources and plant propagation events. The EST-SNPs revealed a clear cut off between inter- and intra-cultivar variation in olive. Besides, they were able to reliably discriminate among different accessions, to detect possible homonymy cases as well as efficiently ascertain the presence of redundant germplasm in the collection. Additionally, these markers were highly transferable to the wild genotypes. These results, together with the low genotyping error rates and the easy and fully automated procedure used to get the genotyping data, validate the new set of EST-SNPs as possible markers of choice for olive cultivar identification. PMID- 30298077 TI - Use of Biostimulants for Organic Apple Production: Effects on Tree Growth, Yield, and Fruit Quality at Harvest and During Storage. AB - The experiment was conducted during two consecutive seasons (years 2016 and 2017) in an organic apple orchard of the cultivar Jonathan. Several biostimulants were tested (10 in total), including humic acids, macro and micro seaweed extracts, alfalfa protein hydrolysate, amino acids alone or in combination with zinc, B group vitamins, chitosan and a commercial product containing silicon. Treatments were performed at weekly intervals, starting from the end of May until mid August. The macroseaweed extract was effective in stimulate tree growth potential in both years, as shown by a significantly larger leaf area (+20% as compared to control) and by an higher chlorophyll content and leaf photosynthetic rate in year 2016. As for the yield performances and apples quality traits at harvest (average fruit weight, soluble solids content, titratable acidity, and flesh firmness), they were generally affected by the different climatic conditions that characterized the two growing seasons (year 2017 being characterized by higher maximal and average temperatures and by limited rainfalls at the beginning of the season). Treatments with macroseaweed extract, B-group vitamins and alfalfa protein hydrolysate were able to significantly improve the intensity and extension of the red coloration of apples at harvest. Correspondingly, the anthocyanin content in the skin of apples treated with the same biostimulants resulted significantly higher than control, highlighting the potential influence of these substances on the synthesis of secondary metabolites in apple. The incidence of physiological disorders was also monitored during apple storage period. Amino acids plus zinc application was effective in reducing (more than 50%) the incidence of the "Jonathan spot," the main post-harvest disorder for this cultivar. PMID- 30298078 TI - Redox Regulation of Starch Metabolism. AB - Metabolism of starch is a major biological integrator of plant growth supporting nocturnal energy dynamics by transitory starch degradation as well as periods of dormancy, re-growth, and reproduction by utilization of storage starch. Especially, the extraordinarily well-tuned and coordinated rate of transient starch biosynthesis and degradation suggests the presence of very sophisticated regulatory mechanisms. Together with the circadian clock, land plants (being autotrophic and sessile organisms) need to monitor, sense, and recognize the photosynthetic rate, soil mineral availability as well as various abiotic and biotic stress factors. Currently it is widely accepted that post-translational modifications are the main way by which the diel periodic activity of enzymes of transient starch metabolism are regulated. Among these mechanisms, thiol-based redox regulation is suggested to be of fundamental importance and in chloroplasts, thioredoxins (Trx) are tightly linked up to photosynthesis and mediate light/dark regulation of metabolism. Also, light independent NADP thioredoxin reductase C (NTRC) plays a major role in reactive oxygen species scavenging. Moreover, Trx and NTRC systems are interconnected at several levels and strongly influence each other. Most enzymes involved in starch metabolism are demonstrated to be redox-sensitive in vitro. However, to what extent their redox sensitivity is physiologically relevant in synchronizing starch metabolism with photosynthesis, heterotrophic energy demands, and oxidative protection is still unclear. For example, many hydrolases are activated under reducing (light) conditions and the strict separation between light and dark metabolic pathways is now challenged by data suggesting degradation of starch during the light period. PMID- 30298079 TI - Dual or Not Dual?-Comparative Analysis of Fluorescence Microscopy-Based Approaches to Study Organelle Targeting Specificity of Nuclear-Encoded Plant Proteins. AB - Plant cells are unique as they carry two organelles of endosymbiotic origin, namely mitochondria and chloroplasts (plastids) which have specific but partially overlapping functions, e. g., in energy and redox metabolism. Despite housing residual genomes of limited coding capacity, most of their proteins are encoded in the nucleus, synthesized by cytosolic ribosomes and need to be transported "back" into the respective target organelle. While transport is in most instances strictly monospecific, a group of proteins carries "ambiguous" transit peptides mediating transport into both, mitochondria and plastids. However, such dual targeting is often disputed due to variability in the results obtained from different experimental approaches. We have therefore compared and evaluated the most common methods established to study protein targeting into organelles within intact plant cells. All methods are based on fluorescent protein technology and live cell imaging. For our studies, we have selected four candidate proteins with proven dual targeting properties and analyzed their subcellular localization in vivo utilizing four different methods (particle bombardment, protoplast transformation, Agrobacterium infiltration, and transgenic plants). Though using identical expression constructs in all instances, a given candidate protein does not always show the same targeting specificity in all approaches, demonstrating that the choice of method is important, and depends very much on the question to be addressed. PMID- 30298080 TI - Overexpression of a NF-YC Gene Results in Enhanced Drought and Salt Tolerance in Transgenic Seashore Paspalum. AB - Seashore paspalum (Paspalum vaginatum O. Swartz) is an important warm-season turfgrass species. In this study we generated transgenic seashore paspalum overexpressing CdtNF-YC1, a nuclear factor Y transcription factor from hybrid bermudagrass (Cynodon dactylon * Cynodon transvaalensis). DNA blot hybridization and qRT-PCR analysis showed that CdtNF-YC1 was integrated into the genomes of transgenic seashore paspalum plants and expressed. Reduced relative water content (RWC) and survival rate and increased ion leakage were observed in both wild type (WT) and transgenic plants after drought stress, while transgenic plants had higher levels of RWC and survival rate and lower ion leakage than the WT. Maximal photochemical efficiency of photosystem II (F v/F m), chlorophyll concentration and survival rate were decreased after salt stress, while higher levels were maintained in transgenic plants than in WT. In addition, an increased Na+ content and decreased or unaltered K+ in leaves and roots were observed after salt treatment, while lower level of Na+ and higher levels of K+ and K+/ Na+ ratio were maintained in transgenic plants than in WT. The results indicated that overexpressing CdtNF-YC1 resulted in enhanced drought and salt tolerance in transgenic plants. Transcript levels of stress responsive genes including PvLEA3, PvP5CS1, PvABI2, and PvDREB1B were induced in response to drought and salt stress, and higher levels were observed in transgenic seashore paspalum than in WT. The results suggest that the enhanced drought and salt tolerance in transgenic seashore paspalum is associated with induction of a series of stress responsive genes as a result of overexpression of CdtNF-YC1. PMID- 30298081 TI - Rapeseed Seedling Stand Counting and Seeding Performance Evaluation at Two Early Growth Stages Based on Unmanned Aerial Vehicle Imagery. AB - The development of unmanned aerial vehicles (UAVs) and image processing algorithms for field-based phenotyping offers a non-invasive and effective technology to obtain plant growth traits such as canopy cover and plant height in fields. Crop seedling stand count in early growth stages is important not only for determining plant emergence, but also for planning other related agronomic practices. The main objective of this research was to develop practical and rapid remote sensing methods for early growth stage stand counting to evaluate mechanically seeded rapeseed (Brassica napus L.) seedlings. Rapeseed was seeded in a field by three different seeding devices. A digital single-lens reflex camera was installed on an UAV platform to capture ultrahigh resolution RGB images at two growth stages when most rapeseed plants had at least two leaves. Rapeseed plant objects were segmented from images of vegetation indices using typical Otsu thresholding method. After segmentation, shape features such as area, length-width ratio and elliptic fit were extracted from the segmented rapeseed plant objects to establish regression models of seedling stand count. Three row characteristics (the coefficient of variation of row spacing uniformity, the error rate of the row spacing and the coefficient of variation of seedling uniformity) were further calculated for seeding performance evaluation after crop row detection. Results demonstrated that shape features had strong correlations with ground-measured seedling stand count. The regression models achieved R-squared values of 0.845 and 0.867, respectively, for the two growth stages. The mean absolute errors of total stand count were 9.79 and 5.11% for the two respective stages. A single model over these two stages had an R-squared value of 0.846, and the total number of rapeseed plants was also accurately estimated with an average relative error of 6.83%. Moreover, the calculated row characteristics were demonstrated to be useful in recognizing areas of failed germination possibly resulted from skipped or ineffective planting. In summary, this study developed practical UAV-based remote sensing methods and demonstrated the feasibility of using the methods for rapeseed seedling stand counting and mechanical seeding performance evaluation at early growth stages. PMID- 30298082 TI - Discovering Causal Relationships in Grapevine Expression Data to Expand Gene Networks. A Case Study: Four Networks Related to Climate Change. AB - In recent years the scientific community has been heavily engaged in studying the grapevine response to climate change. Final goal is the identification of key genetic traits to be used in grapevine breeding and the setting of agronomic practices to improve climatic resilience. The increasing availability of transcriptomic studies, describing gene expression in many tissues and developmental, or treatment conditions, have allowed the implementation of gene expression compendia, which enclose a huge amount of information. The mining of transcriptomic data represents an effective approach to expand a known local gene network (LGN) by finding new related genes. We recently published a pipeline based on the iterative application of the PC-algorithm, named NES2RA, to expand gene networks in Escherichia coli and Arabidopsis thaliana. Here, we propose the application of this method to the grapevine transcriptomic compendium Vespucci, in order to expand four LGNs related to the grapevine response to climate change. Two networks are related to the secondary metabolic pathways for anthocyanin and stilbenoid synthesis, involved in the response to solar radiation, whereas the other two are signaling networks, related to the hormones abscisic acid and ethylene, possibly involved in the regulation of cell water balance and cuticle transpiration. The expansion networks produced by NES2RA algorithm have been evaluated by comparison with experimental data and biological knowledge on the identified genes showing fairly good consistency of the results. In addition, the algorithm was effective in retaining only the most significant interactions among the genes providing a useful framework for experimental validation. The application of the NES2RA to Vitis vinifera expression data by means of the BOINC based implementation is available upon request (valter.cavecchia@cnr.it). PMID- 30298083 TI - Spatial Patterns of Leaf Carbon, Nitrogen, and Phosphorus Stoichiometry of Aquatic Macrophytes in the Arid Zone of Northwestern China. AB - Ecological stoichiometry is a powerful indicator for understanding the adaptation of plants to environment. However, understanding of stoichiometric characteristics of leaf carbon (C%), nitrogen (N%), and phosphorus (P%) for aquatic macrophytes remains limited. In this study, 707 samples from 146 sites were collected to study the variations in leaf C%, N%, and P%, and tried to explore how different environmental conditions affect leaf C, N, and P stoichiometry. Results showed that the mean values of leaf C%, N%, P%, and N:P ratios were 39.95%, 2.12%, 0.14%, and 16.60% of macrophytes across the arid zone of northwestern China, respectively. And the mean values of leaf P% were lower than those from the Tibetan Plateau and eastern China, which maybe due to an adaptation strategy of the plants to the unique conditions in the arid zone in the long-term evolutionary process. The higher N:P ratios suggested that P was established as the limiting factor of the macrophytes communities in the arid zone of northwestern China. There were significant differences in leaf C%, N%, P%, and their ratios among different life forms. Our results also showed strong relationships between leaf N% and N:P ratios and longitude, leaf N%, P%, and N:P ratios and latitude, and leaf N% and P% and altitude, respectively. In addition, the results showed that pH can significantly influence leaf C%. Our results supported the temperature-plant physiology hypothesis owing to a negative relationship between leaf N% and P% of macrophytes and mean annual temperature in the arid zone of northwestern China. The different patterns of leaf stoichiometry between the arid zone of northwestern China and eastern China indicated that there were different physiological and ecological adaptability of macrophytes to environmental gradients in different climatic zones. PMID- 30298084 TI - The Phytogeographic History of Common Walnut in China. AB - Common walnut (Juglans regia L.) is an economically important hardwood tree species cultivated worldwide for its high quality wood and edible nuts. It is generally accepted that after the last glaciation J. regia survived and grew in almost completely isolated stands in Asia, and that ancient humans dispersed walnuts across Asia and into new habitats via trade and cultural expansion. The history of common walnut in China is a matter of debate, however. We estimated the genetic diversity and spatial genetic structure of 31 walnut populations sampled across its Chinese range using 22 microsatellite markers (13 neutral and 9 non-neutral). Using historical data and population genetic analysis, including approximate Bayesian analysis (ABC), we reconstructed the demographic history of J. regia in China. The genetic data indicated the likely presence of J. regia in glacial refugia in the Xinjiang province (Northwest China), Northeastern China (Beijing, Shandong, and Changbai Mountains), Central China (Qinling and Baishan Mountains and Xi'an), and Southwestern China (Tibet, Yunnan, Guizhou, and Sichuan provinces). Based on DIY-ABC analysis, we identified three ancient lineages of J. regia in China. Two lineages (subpopulation A and subpopulation B+C) diverged about 2.79 Mya, while Southwestern China, and Qinling and Baishan Mountains lineages diverged during the Quaternary glaciations (about 1.13 Mya). Remnants of these once-distinct genetic clusters of J. regia may warrant ecological management if they are to be retained as in situ resources. A population size expansion in Northeastern China was detected in the last five centuries. The present distribution of walnut in China resulted from the combined effects of expansion/contraction from multiple refugia after the Last Glacial Maximum and later human exploitation. PMID- 30298085 TI - The Current Status and Development of Insect-Resistant Genetically Engineered Poplar in China. AB - Poplar is one of the main afforestation tree species in China, and the use of a single, or only a few, clones with low genetic diversity in poplar plantations has led to increasing problems with insect pests. The use of genetic engineering to cultivate insect-resistant poplar varieties has become a hot topic. Over the past 20 years, there have been remarkable achievements in this area. To date, nearly 22 insect-resistant poplar varieties have been created and approved for small-scale field testing, environmental release, or pilot-scale production. Here, we comprehensively review the development of insect-resistant genetically modified (GM) poplars in China. This review mostly addresses issues surrounding the regulation and commercialization of Bt poplar in China, the various insecticidal genes used, the effects of transgenic poplars on insects, toxic protein expression, multigene transformation, the stability of insect resistance, and biosafety. The efficacy of GM poplars for pest control differed among different transgenic poplar clones, larval instars, and insect species. The Bt protein analysis revealed that the expression level of Cry3A was significantly higher than that of Cry1Ac. Temporal and spatial studies of Bt protein showed that its expression varied with the developmental stage and tissue. The inheritance and expression of the exogenous gene were reviewed in transgenic hybrid poplar progeny lines and grafted sections. Biosafety issues, in terms of transgene stability and the effects on soil microorganisms, natural enemies of insects, and arthropod communities are also discussed. PMID- 30298086 TI - Intracytoplasmic Re-localization of miRISC Complexes. AB - MicroRNAs (miRNAs) are a conserved class of non-coding RNAs of 22 nucleotides that post-transcriptionally regulate gene expression through translational repression and/or mRNA degradation. A great progress has been made regarding miRNA biogenesis and miRNA-mediated gene regulation. Additionally, an ample amount of information exists with respect to the regulation of miRNAs. However, the cytoplasmic localization of miRNAs and its effect on gene regulatory output is still in progress. We provide a current review of the cytoplasmic miRNA localization in metazoans. We then discuss the dynamic changes in the intracytoplasmic localization of miRNAs as a means to regulate their silencing activity. We then conclude our discussion with the potential molecules that could modulate miRNA localization. PMID- 30298088 TI - Medical Image Classification Based on Deep Features Extracted by Deep Model and Statistic Feature Fusion with Multilayer Perceptron?. AB - Medical image classification is a key technique of Computer-Aided Diagnosis (CAD) systems. Traditional methods rely mainly on the shape, color, and/or texture features as well as their combinations, most of which are problem-specific and have shown to be complementary in medical images, which leads to a system that lacks the ability to make representations of high-level problem domain concepts and that has poor model generalization ability. Recent deep learning methods provide an effective way to construct an end-to-end model that can compute final classification labels with the raw pixels of medical images. However, due to the high resolution of the medical images and the small dataset size, deep learning models suffer from high computational costs and limitations in the model layers and channels. To solve these problems, in this paper, we propose a deep learning model that integrates Coding Network with Multilayer Perceptron (CNMP), which combines high-level features that are extracted from a deep convolutional neural network and some selected traditional features. The construction of the proposed model includes the following steps. First, we train a deep convolutional neural network as a coding network in a supervised manner, and the result is that it can code the raw pixels of medical images into feature vectors that represent high level concepts for classification. Second, we extract a set of selected traditional features based on background knowledge of medical images. Finally, we design an efficient model that is based on neural networks to fuse the different feature groups obtained in the first and second step. We evaluate the proposed approach on two benchmark medical image datasets: HIS2828 and ISIC2017. We achieve an overall classification accuracy of 90.1% and 90.2%, respectively, which are higher than the current successful methods. PMID- 30298090 TI - Outcomes Following Salvage Radiation and Systemic Therapy for Isolated Locoregional Recurrence of Breast Cancer after Mastectomy: Impact of Constructed Biologic Subtype. AB - Purpose: This study examines factors associated with outcomes following salvage radiation and systemic therapy for breast cancer patients who developed isolated locoregional recurrence (ILRR) after mastectomy alone, while focusing on the prognostic significance of constructed biologic subtype in this setting. Methods and Materials: 269 postmastectomy patients in total treated for ILRR were included. Cumulative incidence of locoregional control (LRC), distant metastasis (DM)-free survival (DMFS), disease-free survival (DFS), and overall survival (OS) were calculated using Kaplan-Meier method. For statistical analysis, biologic subtypes were constructed from hormonal receptors (Rec) and HER2, consisting of Rec+/HER2-, Rec+/HER2+, Rec-/HER2+, and Rec-/HER2-. The association of clinic pathological and treatment-related parameters with outcomes was evaluated using a Cox regression model. Results: At a median follow-up of 65 months, 56 (20.8%) patients failed to secure LRC after radiotherapy, and 165 patients (61.3%) developed DM. Overall, the actuarial 5-year LRC, DMFS, DFS, and OS rate was 77.3%, 45.6%, 43.9%, and 66.8%, respectively. Multivariate analysis revealed that constructed biologic subtype represented the most significant prognostic factor for any outcome. Compared to patients with Rec+/HER2- disease, those with Rec /HER2- had significantly poorer 5-year LRC (84.2% versus 58.3%, HR = 4.36, P < 0.001) and worse survivals including 5-year DMFS (63.0% versus 15.8%, HR = 4.28, P < 0.001), DFS (59.7% versus 13.6%, HR=3.92, P < 0.001), and OS (87.8% versus 22.3%, HR = 8.55, P < 0.001). Other factors associated with reduced LRC were no radical surgery and involved field irradiation alone, whereas factors associated with poor survivals included positive nodes at primary diagnosis and regional recurrence. Conclusions: Constructed biologic subtypes remained to be predictive of both disease control and survivals after salvage radiation for postmastectomy ILRR. Notably, Rec-/HER2- patients were demonstrated to be at high risk of locoregional failure and subsequent DM and tended to have worse survivals despite salvage therapies. PMID- 30298089 TI - Laparoscopic Spleen-Preserving Distal Pancreatectomy (LSPDP) with Preservation of Splenic Vessels: An Inferior-Posterior Approach. AB - Objective: To summarize the operation experience of laparoscopic spleen preserving distal pancreatectomy (LSPDP) with preservation of splenic vessels by an inferior-posterior dissection of the pancreatic body and evaluate its feasibility. Methods: Patients undergoing LSPDS at Ningbo Li Huili Hospital and Ningbo Li Huili Eastern Hospital from January 2014 to April 2017 were recruited in this study and were analyzed retrospectively. They were divided into two groups based on the surgical approach: the inferior-posterior approach group and the other approach group. We sought to compare outcomes of the two groups. Results: The LSPDP procedure was completed successfully in 49 cases, and 48 patients had their splenic artery and vein preserved, including 26 cases in the inferior-posterior approach group and 22 cases in the other approach group. There were no significant differences between the two groups with respect to age (p = 0.18), sex (p = 0.56), preoperative diabetes (p = 1.00), ASA grading (p = 1.00), tumor size (p = 0.91), intraoperative blood loss (t = -0.01, p = 0.99), hospital stay (t = -0.02, p = 0.98), and pancreatic fistula rates (p = 1.00). Patients undergoing LSPDP by the inferior-posterior approach had a shorter operative time (t = -4.13, p < 0.001) than the other approach group. Conclusions: LSPDS by the inferior-posterior approach associated with shorter operative time is safe and feasible. PMID- 30298091 TI - Knowledge, Attitudes, and Practices on Infection Control Measures in Stomatology Students in Lima, Peru. AB - Introduction: The level of knowledge, attitudes, and practices with respect to infection control measures in undergraduate stomatology students is not well understood; that is why these variables were evaluated in the students of the Universidad Privada San Juan Bautista between September and November of 2017. Methods: A cross-sectional study was carried out. A total of 347 students from the Ica, Lima Norte, and Chorrillos campuses were evaluated. The sample was calculated using the statistical formula of comparison of means. The questionnaire of the CDC (Center of Contagious Diseases) was used to measure the variables described. Results: It was observed that 72.05% of the students preferred to use oral rinsing before starting a treatment, 72.62% used the autoclave as the primary equipment to sterilize their instruments in the dental clinic, 95.10% considered that isolation is important in the control of the infection, 46.40% affirmed that tuberculosis is the most infectious disease, and only 26.51% considered it to be hepatitis B. On the other hand, it was found that the scores of knowledge, attitudes, and practices were 2.74 +/- 2.16, 3.59 +/- 0.88, and 3.59 +/- 1.73, respectively. Conclusions: The level of knowledge was low among the students evaluated; however, as far as the level of practices and attitudes was high, even so, this topic must be reinforced so that stomatology students reflect on the importance of the risks that exist to get infected with any disease inside the dental office, as outside of it. PMID- 30298087 TI - De novo Mutations (DNMs) in Autism Spectrum Disorder (ASD): Pathway and Network Analysis. AB - Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder (NDD) defined by impairments in social communication and social interactions, accompanied by repetitive behavior and restricted interests. ASD is characterized by its clinical and etiological heterogeneity, which makes it difficult to elucidate the neurobiological mechanisms underlying its pathogenesis. Recently, de novo mutations (DNMs) have been recognized as strong source of genetic causality. Here, we review different aspects of the DNMs associated with ASD, including their functional annotation and classification. In addition, we also focus on the most recent advances in this area, such as the detection of PZMs (post-zygotic mutations), and we outline the main bioinformatics tools commonly employed to study these. Some of these approaches available allow DNMs to be analyzed in the context of gene networks and pathways, helping to shed light on the biological processes underlying ASD. To end this review, a brief insight into the future perspectives for genetic studies into ASD will be provided. PMID- 30298092 TI - Therapy of Dredging the Bowels Enhanced the Neuroprotective Effect of Nourishing Kidney Herbs on Hippocampal Cholinergic System in Alzheimer's Disease Model Rat Induced by Abeta 1-42. AB - Background: Therapy of nourishing kidney has been used for treating memory deficits of Alzheimer's disease (AD) for thousands of years based on traditional Chinese medicine. However, we found the therapy of dredging the bowels could alleviate both memory deficits and mental symptoms of AD in clinic. Objective: To determine whether the therapy of dredging the bowels could enhance the neuroprotective effect of nourishing kidney herbs for treating AD rats, and to explore the underlying mechanism of the combination of nourishing kidney and dredging the bowels (NKDB) herbs. Methods: 60 rats were randomly divided into sham-operated group (SOG), model group (MG), nourishing kidney group (NKG), dredging the bowels group (DBG), nourishing kidney and dredging the bowels group (NKDBG), and donepezil hydrochloride group (DHG). The model establishment was performed by injecting Abeta 1-42 into the hippocampal CA1 region. Animals received aqueous solution of Chinese herbal medicine or western medicine while SOG received only distilled water. Ability of learning and memory were assessed by Morris water maze. Acetylcholinesterase(AChE) and choline acetyltransferase (ChAT) activity and positive cells in the hippocampus were detected by the biochemical and immunofluorescent assay. Results: All rats were in the same baseline. While after model establishment, ability of learning and memory of MG, NKG, DBG, NKDBG, and DHG were significantly impaired compared with SOG. Whereas after treatment, ability of learning and memory of NKG, DBG, NKDBG, and DHG were significantly improved compared with MG. Additionally, AChE activity of NKG, DBG, and NKDBG was significantly decreased, meanwhile ChAT activity showed an increased tendency. The number of AChE-positive cells and ChAT-positive cells of both NKDBG and DHG were significantly decreased and increased respectively, superior to those when compared with NKG and DBG. What's more, there was no significant difference between NKDBG and DHG. Conclusion: Therapy of dredging the bowels could enhance the neuroprotective effect of nourishing kidney herbs by reversing morphological damage of hippocampal cholinergic system. Furthermore, treatment with NKDB herbs could be effectively against AD, providing a practical therapeutic strategy in clinic. PMID- 30298093 TI - (+)-Usnic Acid Inhibits Migration of c-KIT Positive Cells in Human Colorectal Cancer. AB - Inhibition of tumor cell migration is a treatment strategy for patients with colorectal cancer (CRC). SCF-dependent activation of c-KIT is responsible for migration of c-KIT positive [c-KIT(+)] cells of CRC. Drug resistance to Imatinib Mesylate (c-KIT inhibitor) has emerged. Inhibition of mTOR can induce autophagic degradation of c-KIT. (+)-usnic acid [(+)-UA], isolated from lichens, has two major functions including induction of proton shuttle and targeting inhibition of mTOR. To reduce hepatotoxicity, the treatment concentration of (+)-UA should be lower than 10 MUM. HCT116 cells and LS174 cells were employed to investigate the inhibiting effect of (+)-UA (<10 MUM) on SCF-mediated migration of c-KIT(+) CRC cells. HCT116 cells were employed to investigate the molecular mechanisms. The results indicated that firstly, 8 MUM (+)-UA decreased ATP content via uncoupling; secondly, 8 MUM (+)-UA induced mTOR inhibition, thereby mediated activation suppression of PKC-A, and induced the autophagy of the completed autophagic flux that resulted in the autophagic degradation and transcriptional inhibition of c-KIT and the increase in LDH release; ultimately, 8 MUM (+)-UA inhibited SCF-mediated migration of CRC c-KIT(+) cells. Taken together, 8 MUM could be determined as the effective concentration for (+)-UA to inhibit SCF mediated migration of CRC c-KIT(+) cells. PMID- 30298094 TI - Role of Acupuncture in the Management of Severe Acquired Brain Injuries (sABIs). AB - Acupuncture therapy has been used to treat several disorders in Asian countries and its use is increasing in Western countries as well. Current literature assessed the safety and efficacy of acupuncture in the acute management and rehabilitation of patients with neurologic disorders. In this paper, the role of acupuncture in the treatment of acute severe acquired brain injuries is described, acting on neuroinflammation, intracranial oedema, oxidative stress, and neuronal regeneration. Moreover, beneficial effects of acupuncture on subacute phase and chronic outcomes have been reported in controlling the imbalance of IGF-1 hormone and in decreasing spasticity, pain, and the incidence of neurovegetative crisis. Moreover, acupuncture may have a positive action on the arousal recovery. Further work is needed to understand the effects of specific acupoints on the brain. Allegedly concurrent neurophysiological measurements (e.g., EEG) may help in studying acupuncture-related changes in central nervous system activity and determining its potential as an add-on rehabilitative treatment for patients with consciousness disorders. PMID- 30298095 TI - Estimating Treatment Effects for Recurrent Events in the Presence of Rescue Medications: An Application to the Immune Thrombocytopenia Study. AB - In many clinical studies, patients may experience the same type of event of interest repeatedly over time. However, the assessment of treatment effects is often complicated by the rescue medication uses due to ethical reasons. For example, in the motivating trial in studying the Immune Thrombocytopenia (ITP), when the interest lies in evaluating the treatment benefit of investigational product (IP) on reducing patient's repeated bleeding, rescue medication such as platelet transfusions may be allowed to raise platelet counts. Both the intention to-treat analysis and treating the intermediate rescue medication as covariate tend to attenuate the treatment benefit, and the estimates can be biased if interpreted as causal. In this paper, we propose a general causal framework when intermediate rescue medications are informative. We adopt the inverse weighted estimation approach to estimate the treatment effect, where weights are constructed to reflect time-dependent medication use probabilities. The proposed estimators are shown to be asymptotically normal and are demonstrated to perform well in small-sample simulation studies. The application to the ITP studies reveals a stronger benefit of using IP in reducing bleeding. PMID- 30298096 TI - The Long-Term Efficacy and Safety of Carotid Artery Stenting among the Elderly: A Single-Center Study in China. AB - Compared to carotid endarterectomy, carotid artery stenting (CAS) is reportedly associated with higher perioperative risks in elderly patients. To verify the long-term safety and efficacy of CAS with embolic protection in elderly patients, we retrospectively reviewed the medical records of patients with carotid stenosis treated between January 2003 and March 2010 at the Department of Neurology of a large university hospital in China. We included patients with symptomatic, moderate, or severe carotid stenosis of atherosclerotic etiology (other etiologies were excluded), with a disability score <= 3 on the modified Rankin Scale, and who received CAS instead of carotid endarterectomy. The clinical endpoints studied were stroke recurrence and all-cause death. The 84 patients included in this study (median follow-up, 8.08 years) were stratified according to age at surgery (<70 vs. >=70 years), and no significant between-group difference was found regarding baseline characteristics. Of the 14 patients (16.67%) who experienced a defined clinical endpoint, 4 (7.14%) were aged <70 years and 10 (35.71%) were aged >=70 years (P = 0.002). Overall mortality was 14.29% (12/84), with 3 (5.36%) and 9 (32.14%) deaths among patients aged <70 and >= 70 years, respectively (P = 0.002). Heart disease and cancer accounted for most deaths. The two groups did not differ regarding stroke recurrence, disability score, or rate of in-stent restenosis (blockage >= 50%), but patients aged >=70 years had a higher risk of mortality (odds ratio, 8.3684; 95% confidence interval, 2.048-34.202; P = 0.003), and age was an independent risk factor for death (odds ratio, 20.054; 95% confidence interval, 3.094-129.987, P = 0.002). Among elderly patients in Southwest China, CAS can effectively prevent stroke recurrence without increasing the risk of stroke-related death, but the risk of all-cause death is higher, with age as an independent risk factor. Careful patient selection is of key importance in the treatment of symptomatic carotid artery stenosis. PMID- 30298097 TI - Evaluation of A-Site Ba2+-Deficient Ba1-x Co0.4Fe0.4Zr0.1Y0.1O3-delta Oxides as Electrocatalysts for Efficient Hydrogen Evolution Reaction. AB - Exploring earth-abundant and cost-effective catalysts with high activity and stability for a hydrogen evolution reaction (HER) is of great importance to practical applications of alkaline water electrolysis. Here, we report on A-site Ba2+-deficiency doping as an effective strategy to enhance the electrochemical activity of BaCo0.4Fe0.4Zr0.1Y0.1O3-delta for HER, which is related to the formation of oxygen vacancies around active Co/Fe ions. By comparison with the benchmarking Ba0.5Sr0.5Co0.8Fe0.2O3-delta , one of the most spotlighted perovskite oxides, the Ba0.95Co0.4Fe0.4Zr0.1Y0.1O3-delta oxide has lower overpotential and smaller Tafel slope. Furthermore, the Ba0.95Co0.4Fe0.4Zr0.1Y0.1O3-delta catalyst is ultrastable in an alkaline solution. The enhanced HER performance originated from the increased active atoms adjacent to oxygen vacancies on the surface of the Ba0.95Co0.4Fe0.4Zr0.1Y0.1O3 delta catalyst induced by Ba2+-deficiency doping. The low-coordinated active atoms and adjacent oxygen ions may play the role of heterojunctions that synergistically facilitate the Volmer process and thus render stimulated HER catalytic activity. The preliminary results suggest that Ba2+-deficiency doping is a feasible method to tailor the physical and electrochemical properties of perovskite, and that Ba0.95Co0.4Fe0.4Zr0.1Y0.1O3-delta is a potential catalyst for HER. PMID- 30298098 TI - MULTI-ENERGY CONE-BEAM CT RECONSTRUCTION WITH A SPATIAL SPECTRAL NONLOCAL MEANS ALGORITHM. AB - Multi-energy computed tomography (CT) is an emerging medical image modality with a number of potential applications in diagnosis and therapy. However, high system cost and technical barriers obstruct its step into routine clinical practice. In this study, we propose a framework to realize multi-energy cone beam CT (ME-CBCT) on the CBCT system that is widely available and has been routinely used for radiotherapy image guidance. In our method, a kVp switching technique is realized, which acquires x-ray projections with kVp levels cycling through a number of values. For this kVp-switching based ME-CBCT acquisition, x-ray projections of each energy channel are only a subset of all the acquired projections. This leads to an undersampling issue, posing challenges to the reconstruction problem. We propose a spatial spectral non-local means (ssNLM) method to reconstruct ME-CBCT, which employs image correlations along both spatial and spectral directions to suppress noisy and streak artifacts. To address the intensity scale difference at different energy channels, a histogram matching method is incorporated. Our method is different from conventionally used NLM methods in that spectral dimension is included, which helps to effectively remove streak artifacts appearing at different directions in images with different energy channels. Convergence analysis of our algorithm is provided. A comprehensive set of simulation and real experimental studies demonstrate feasibility of our ME-CBCT scheme and the capability of achieving superior image quality compared to conventional filtered backprojection-type (FBP) and NLM reconstruction methods. PMID- 30298099 TI - Strategic Improvement for Quality and Satisfaction of Hospital Information Systems. AB - The purpose of our study aimed to identify attributes capable of improving physicians' satisfaction levels with the use of a hospital information system (HIS). A model inclusive of system quality, information quality, and service quality related to an HIS is used to form antecedents of user satisfaction. Survey methodology was used to collect an attributive set representing the system quality, information quality, and service quality made available from 150 physicians at a large health-care system in southern Taiwan. Responses were segmented into low and high satisfaction and analyzed with partial least squares and importance-performance analysis. The results reveal that system quality, information quality, and service quality may be used to significantly predict physicians' satisfaction. Two system quality attributes (reliability and response time) were identified as the highest priorities for intervention by low- and high satisfaction users. Low-satisfaction users further expect improvement of the HIS service quality to take place. The subject health-care system should produce coping interventions for those high priorities to enhance the satisfaction of physicians. PMID- 30298100 TI - A Filtering Method for Identification of Significant Target mRNAs of Coexpressed and Differentially Expressed MicroRNA Clusters. AB - MicroRNA (miRNA) binding is primarily based on sequence, but structure-specific binding is also possible. Various prediction algorithms have been developed for predicting miRNA target genes; the results, however, have relatively high levels of false positives, and the degree of overlap between predicted targets from different methods is poor or null. We devised a new method for identifying significant miRNA target genes from an extensive list of predicted miRNA target gene relationships using hypergeometric distributions. We evaluated our method in statistical and semantic aspects using a common miRNA cluster from six solid tumors. Our method provides statistically and semantically significant miRNA target genes. Complementing target prediction algorithms with our proposed method may have a significant synergistic effect in finding and evaluating functional annotation and enrichment analysis for miRNA. PMID- 30298101 TI - Stroke Outcome and Determinants among Patients with and without Diabetes in a Tertiary Hospital in Ghana. AB - Background: Diabetes mellitus, a well-established independent risk factor for stroke, has varied association with stroke outcome from previous studies. This study investigated stroke outcome and determinants among patients with and without diabetes in a tertiary hospital in Ghana. Methods: A prospective study conducted among stroke patients with and without diabetes admitted in a Ghanaian tertiary hospital. Baseline clinical and biochemical data were documented. Functional stroke outcome was evaluated at 1, 3, and 6 months after stroke using the modified Rankin Scale. Results: Number of participants enrolled were 326 and 105 (32.20%) had diabetes. Higher proportions of diabetes patients had poor functional stroke outcome at 1, 3, and 6 months (79%, 75.23%, 73.33%) compared with those without diabetes (70.13%, 65.16, 61.99) (p>0.05). Stroke patients with diabetes had lower survival compared with those without diabetes (p=0.0745). Mortality at 6 months was more likely among ischaemic stroke patients with diabetes compared with those without diabetes (Odds Ratio 2.037; CI: 1.058 3.923). Determinants of poor functional stroke outcome for diabetes patients were older age (Adjusted Odds Ratio (AOR)-1.07; CI-1.03-1.12), female gender (AOR 3.74; CI-1.26-12.65), and pneumonia (AOR-11.32; CI-1.93-220.05) whereas the determinants for those without diabetes were unemployment (AOR-4.19; CI-1.24 19.50), speech abnormalities (AOR-1.99; CI1.08-3.73), and pneumonia (AOR-4.05; CI 1.83-9.77). High fasting plasma glucose (HR-1.15; CI-1.07-1.23), elevated temperature (HR-1.41; CI-1.11-1.79), and pneumonia (HR-2.25; CI-1.44-3.50) were determinants of low survival among all stroke patients. Conclusion: Trends towards poorer functional outcome and reduced survival were found among Ghanaian stroke patients with diabetes compared with those without diabetes. Older age, female gender, pneumonia, elevated temperature, and fasting plasma glucose were determinants of adverse outcome in stroke patients with diabetes. PMID- 30298102 TI - Synthesis and Characterization of Ionene-Polyamide Materials as Candidates for New Gas Separation Membranes. AB - A new family of six ionenes containing aromatic amide linkages has been synthesized from ready available starting materials at scales up to ~50 g. These ionene-polyamides are all constitutional isomers and vary only in the regiochemistry of the amide linkages (para, meta) and xylyl linkages (ortho, meta, para) which are present in the polymer backbone. This paper details the synthesis of these ionenes and associated characterizations. Ionene-polyamides exhibit relatively low melting points (~150 oC) allowing them to be readily processed into films and other objects. These ionene-polyamide materials are being developed for further study as polymer membranes for the separations of gases such as CO2, N2, CH4 and H2. PMID- 30298103 TI - Assimilation of MODIS Snow Cover Fraction Observations into the NASA Catchment Land Surface Model. AB - The NASA Catchment land surface model (CLSM) is the land model component used for the Modern-Era Retrospective Analysis for Research and Applications (MERRA). Here, the CLSM versions of MERRA and MERRA-Land are evaluated using snow cover fraction (SCF) observations from the Moderate Resolution Imaging Spectroradiometer (MODIS). Moreover, a computationally-efficient empirical scheme is designed to improve CLSM estimates of SCF, snow depth, and snow water equivalent (SWE) through the assimilation of MODIS SCF observations. Results show that data assimilation (DA) improved SCF estimates compared to the open-loop model without assimilation (OL), especially in areas with ephemeral snow cover and mountainous regions. A comparison of the SCF estimates from DA against snow cover estimates from the NOAA Interactive Multisensor Snow and Ice Mapping System showed an improvement in the probability of detection of up to 28% and a reduction in false alarms by up to 6% (relative to OL). A comparison of the model snow depth estimates against Canadian Meteorological Centre analyses showed that DA successfully improved the model seasonal bias from -0.017 m for OL to -0.007 m for DA, although there was no significant change in root-mean-square differences (RMSD) (0.095 m for OL, 0.093 m for DA). The time-average of the spatial correlation coefficient also improved from 0.61 for OL to 0.63 for DA. A comparison against in situ SWE measurements also showed improvements from assimilation. The correlation increased from 0.44 for OL to 0.49 for DA, the bias improved from -0.111 m for OL to -0.100 m for DA, and the RMSD decreased from 0.186 m for OL to 0.180 m for DA. PMID- 30298104 TI - Surgical Synechiolysis of Iridocapsular Adhesion and Sulcus Placement of a Rigid Intraocular Lens on an Oversized Residual Capsular Rim. AB - Purpose: To report the surgical outcomes of surgical synechiolysis of iridocapsular adhesion and sulcus placement of a polymethyl methacrylate scleral sutured intraocular lens (IOL) in aphakic eyes with an oversized residual capsular rim. Methods: Eight aphakic eyes from eight consecutive patients were studied retrospectively. Synechiolysis was performed to maximally expose the residual capsulorhexis. Then, the rigid IOL was placed on the preserved capsulorhexis into the ciliary sulcus. Results: Synechiolysis of iridocapsular adhesion was achieved in all eight eyes intraoperatively. Six eyes had extensive dissection to facilitate IOL sulcus placement. Consequently, seven of the eight eyes had the IOL secured by the residual capsulorhexis, and the other eye had the IOL haptics supported by the narrow residual capsular rim. A visual acuity of 0.25 or above was achieved in four of eight patients, and a well-centered IOL was observed in seven of the eight eyes 26 to 53 months after surgery. A mild IOL decentration was detected in the eye whose capsular rim was not securing the IOL optic. Conclusions: A large-optic and rigid IOL in the sulcus is a feasible alternative when a sulcus-based IOL is considered for aphakic eyes with an oversized residual capsulorhexis. A preserved capsulorhexis after sufficient synechiolysis, which can secure the IOL optic intraoperatively, may yield better stability of the IOL position. PMID- 30298105 TI - Comparison of the Techniques of Secondary Intraocular Lens Implantation after Penetrating Keratoplasty. AB - Aim: To conduct a retrospective analysis of secondary IOL implantation in patients who underwent PK with no simultaneous IOL implantation. Materials and Methods: The retrospective study of the secondary implantation of IOLs was conducted in 46 eyes that underwent a primary operation with PK and cataract/lens extraction with no IOL implantation due to capsule rupture or combining corneal or intraocular complications. The minimum period from PK was 12 months. All secondary IOL implantations were performed from January 2011 to August 2017. Aphakic postkeratoplasty patients were treated using one of the surgical techniques for secondary IOL implantation. In-the-bag IOL implantation was possible if the posterior capsule was complete. If the lens capsule remnants were sufficient to provide secure IOL support, an in-the-sulcus IOL implantation was performed. Scleral fixation was offered in eyes with extensive capsular deficiency or the presence of the vitreous body in anterior chamber. BCVA and expected and achieved refraction were evaluated; we included using two biometry devices, and results were compared. Results: The corrected distance visual acuity (CDVA) before surgery ranged from 0.1 to 0.8 (mean 0.54 +/- 0.17). After secondary IOL implantation, CDVA ranged from 0.2 to 0.8 (mean 0.43 +/- 0.14) at postoperative 1 month and from 0.3 to 0.9 (mean 0.55 +/- 0.15) at postoperative 6 months (p < 0.05). Comparison of the final refraction using two methods of biometry showed no statistically significant difference in the group that underwent scleral fixation of the IOL, similar to the findings for the in-the-bag and in-the-sulcus IOL implantation groups. In the scleral-fixation group, p=0.55 for the USG biometry technique and p=0.22 for the OB technique. p values for the IOL-implantation group were p=0.49 and p=0.44, respectively. Conclusion: Both implantation methods are safe for the patients. Final refraction is depending on the technique and indication to keratoplasty. Both biometry techniques deliver precise data for IOL choice. PMID- 30298108 TI - Early Diagnosis of Nonconvulsive Status Epilepticus Recurrence with Raw EEG of a Bispectral Index Monitor. AB - Background: Seizures are frequent in ICU and their diagnosis is challenging, often delayed or missed. Their diagnosis requires a conventional EEG recording. When cEEG is not available, there is no consensus on how patients should be monitored when there is high risk of seizure. This case illustrates how a bispectral index monitor allowed an early diagnosis of an NCSE recurrence. Case Presentation: A NCSE was diagnosed at the admission. cEEG was not available and then a bispectral index (BIS) monitor was placed and processed parameters were monitored as usual. During the first and second day, both conventional and BIS's EEG showed patterns of burst suppression and the BIS value varied between 25 and 35 while the suppression ratio (SR) varied between 20 and 35. On the third day, while hypnotic drugs were withdrawn progressively, raw EEG of the BIS monitor showed spikes, spikes waves, and polyspikes without significant variation of BIS and SR values. Even if processed parameters stayed between their usual ranges, the typical aspect of the real time EEG raised concern for NCSE recurrence. An unplanned conventional EEG recording was urgently requested, and the diagnosis was confirmed and treated. Conclusion: Primitive and secondary brain injuries can lead to seizures which are often purely electrical. Even though BIS monitors cannot substitute the conventional EEG, processed parameters and raw EEG should be always analysed jointly. In the present case, seizure was suspected only on the aspect of real time EEG which showed spikes, spikes waves, and polyspikes.

AB - Background: Fibroblast growth factor-21 is an endocrine regulator with therapeutic and diagnostic potential. The levels and pattern of circulating FGF 21 have been described mainly in European and Asian populations. Given its strong association with adiposity, and the reported ethnic variabilities in body composition, examining FGF-21 in an African population is crucial. Methods: We measured levels of circulating FGF-21 in 207 overweight and obese Tanzanian males with or without type 2 diabetes mellitus (T2DM), and using statistical approaches, we explored their relationship with anthropometric and biochemical parameters. Results: Consistent with previous reports from European and Asian populations, we found higher levels of FGF-21 in people with T2DM compared to those without the disease. Based on statistical models, measures of adiposity explained up to 59% of the variability in FGF-21 levels in the circulation. Conclusion: Levels of circulating FGF-21 in overweight and obese African males are higher in T2DM and strongly correlate with measures of adiposity. PMID- 30298106 TI - Knockdown of Fibromodulin Inhibits Proliferation and Migration of RPE Cell via the VEGFR2-AKT Pathway. AB - Purpose: Recent research has provided novel insight into the function of fibromodulin (FMOD) in wound healing and angiogenesis. The role of FMOD in initiation of proliferative vitreoretinopathy (PVR) has not been studied. This study investigated the effect of FMOD on human retinal pigment epithelial (RPE) cell, which plays an essential role in the progression of PVR, and the possible mechanisms. Methods: Small interfering (si) RNA-based gene transfer technology was used to decrease FMOD expression and to study its effects on RPEs in vitro. Cell Counting Kit-8 assays, transwells, and flow cytometry analysis were used to measure cell proliferation, migration, cell cycle, and apoptosis. Western blot was used to measure expression of vascular endothelial growth factor (VEGF), VEGF receptor 2 (VEGFR2), extracellular signal-related kinase 1/2 (ERK1/2), and phosphoinositide 3 kinase (PI3K/AKT). Results: After transfection of RPEs with a FMOD-specific siRNA, cell proliferation and migration were inhibited to the percentage of 65% +/- 5% and 39% +/- 10%, respectively, compared to the control group. Depletion of FMOD induced cell cycle arrest and apoptosis in RPE cells. Downregulation of VEGF, VEGFR2, and phosphorylated AKT (p-AKT) were detected in transfected RPEs. Conclusion: Depletion of FMOD selectively downregulated the expression of VEGF and VEGFR2 and inhibited the signaling pathway of AKT phosphorylation, which consequently inhibited the proliferation and migration of RPE Cell. PMID- 30298109 TI - Hemophilia A Complicated by Ulcerative Colitis. AB - Background: Hemophilia A is an X-linked recessive disorder characterized by defective synthesis of Factor VIII protein. Depending on the level of FVIII activity, patients may present with easy bruising, inadequate clotting of traumatic or mild injury, or in severe hemophilia, spontaneous hemorrhage. Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) that is reported to have a decreased frequency of occurrence in subjects with coagulation disorders. Case: A 26-year-old white male with Hemophilia A was admitted for one month of rectal bleeding. The bleeding continued despite Factor VIII replacement and colonoscopy and biopsy were performed confirming the presence of active UC. Conclusion: Ulcerative colitis with underlying F VIII deficiency can result in serious, prolonged, and possibly fatal bleeding if left unrecognized and untreated. Treatment of both conditions concurrently utilizing tertiary facilities and consultations appears to be the safest strategy for management. PMID- 30298110 TI - Elevated CA 125 in a CASE of Leaking Endometrioma. AB - Extremely elevated CA 125, usually suggestive of ovarian malignancy, can be found in physiological or benign conditions such as endometriosis. We present a case of an extremely elevated serum CA 125 level in a patient with stage four endometriosis and bilateral unruptured ovarian endometriomas, with evidence of leakage unilaterally. To avoid costly and unnecessarily invasive tests and procedures it is important to consider the differential diagnosis of endometriosis and/or leaking endometrioma in patients with a profoundly elevated CA 125 level. PMID- 30298111 TI - Changes in Intra-Amniotic, Fetal Intrathoracic, and Intraperitoneal Pressures with Uterine Contraction: A Report of Three Cases. AB - Intra-amniotic, fetal intrathoracic, and intraperitoneal pressures during pregnancy have been previously investigated. However, to our knowledge, changes in these pressures during uterine contractions have not been reported. Herein, we present three cases of polyhydramnios, fetal pleural effusion, and fetal ascites, in which intra-amniotic, fetal intrathoracic, intraperitoneal pressures increased with uterine contractions. These pressure increases may affect the fetal circulation. We suggest that managing potential premature delivery (e.g., with tocolysis) is important in cases with polyhydramnios and excess fluid in fetal body areas, such as the thorax, abdomen, and heart. The results of this preliminary study on intrafetal pressure measurements will be useful in performing fetal and neonatal surgeries in the future. PMID- 30298112 TI - Craniofacial Brown Tumor in Patients with Secondary Hyperparathyroidism to Chronic Renal Failure: Report of Two Cases in Cipto Mangunkusumo Hospital. AB - Brown tumor is a bone lesion that arises in the setting of excess osteoclast activity in hyperparathyroidism. It consists of fibrous tissue, woven bone, and supporting vasculature, while contains no matrix. The characteristic of brown colored lesion is a result of hemosiderin deposition into the osteolytic cysts. Two cases of young women aged 26 and 29 years old, respectively, are known with a history of end-stage renal disease (ESRD). Dialysis is performed two times/week over the last 7 years. Our patients presented with an intraoral mass of the hard palate since 12 months ago and decreased body height of 10 cm. The lesion causes difficulties in swallowing and talking. Laboratory workup showed elevated parathormone or PTH (3.391 pg/mL and >5.000 pg/mL). Neck ultrasound showed enlargement of the parathyroid glands. Supporting examination to diagnose brown tumor are neck ultrasound, CT of the neck, and parathyroid sestamibi scan. We performed parathyroidectomy. Pathology revealed hyperplasia of the parathyroid. The tumor regressed significantly within 2 weeks following the surgery, and we still observe tumor regression as well as reduction in PTH level. As clinicians, we should be alert to other possible causes of bony lesions. Clinical examination, laboratory finding, and imaging present important information to diagnose brown tumor. PMID- 30298113 TI - Management of Small Bowel Perforation by a Bizarre Foreign Body in a 55-Year-Old Woman. AB - Introduction: Ingestion of foreign bodies including dentures, fishbone, screw, and/or surgical devices can be a cause of morbidity, and it rarely could be fatal. Presentation of Case: We present the first hitherto reported case of mussel shell ingestion, which caused acute abdominal pain in a 55-year-old woman. The shell pierced ileal loops, and it was found in the abdominal cavity. Discussion: The accidental or voluntary ingestion of a foreign body is an uncommon event compared to the other causes of bowel perforation. It is fundamental to immediately remove the intestinal fluid, repair the tear, and prevent sepsis, because each delay in diagnosis can lead to a worst outcome. Conclusion: In case of bowel perforation, it important for surgeons, who are dealing with these acute care patients, to be aware of different designs and constructions of possible foreign bodies, in order to be prepared to deal with different possible scenarios and be able to manage them properly. PMID- 30298115 TI - Gas-Phase Synthesis of Nanoparticles: present status and perspectives. AB - There is an increasing interest in the generation of well-defined nanoparticles (NPs) not only because of their size-related particular properties, but also because they are promising building blocks for more complex materials in nanotechnology. Here, we will shortly introduce the gas phase synthesis technology that has evolved rapidly in the last years and allows the fabrication of complex NPs with controllable and tuneable chemical composition and structure while keeping very good control over the size distribution. We will also address some limitations of the technology (stability over time, production yield...) and discuss possible solutions. PMID- 30298114 TI - Emergency Laparoscopic Repair of Giant Left Diaphragmatic Hernia following Minimally Invasive Esophagectomy: Description of a Case and Review of the Literature. AB - Postoperative diaphragmatic hernia (PDH) is an increasingly reported complication of esophageal cancer surgery. PDH occurs more frequently when minimally invasive techniques are employed, but very little is known about its pathogenesis. Currently, no consensus exists concerning preventive measures and its management. A 71-year-old man underwent minimally invasive esophagectomy for esophageal cancer. Three months later, he developed a giant PDH, which was repaired by direct suture via laparoscopic approach. A hypertensive pneumothorax occurred during surgery. This complication was managed by the anaesthesiologist through a high fraction of inspired O2 and several recruitment manoeuvres. The patient remained free of hernia recurrence until he died of neoplastic cachexia 5 months later. Laparoscopic repair of PDH may be safe and effective even in the acute setting and in the case of massive herniation. However, surgeons and anaesthesiologists should be aware of the risk of intraoperative pneumothorax and be prepared to treat it promptly. PMID- 30298116 TI - Analysis of the biodegradation of synthetic testosterone and 17alpha ethynylestradiol using the edible mushroom Lentinula edodes. AB - The mycelium of Lentinula edodes produces enzymes which may degrade xenobiotics including steroid hormones. The aim of the study was to determine whether the mycelium from in vitro cultures of L. edodes are able to degrade endocrine disruptors such as testosterone and 17alpha-ethynylestradiol. To prove the possibility of xenobiotics degradation, cultures of L. edodes were cultivated in an Oddoux liquid medium with the addition of synthetic 17alpha-ethynylestradiol and synthetic testosterone. The endocrine disruptors were extracted from the mycelium and determined qualitatively by RP-HPLC. The degradation products of testosterone and 17alpha-ethynylestradiol were identified using a UPLC/MS/MS analysis. Undegraded testosterone was determined at the amount of 2.97 mg/g dry weight but only in one of the L. edodes extracts from in vitro cultures supplemented with 50 mg of this compound. In turn, 17alpha-ethynylestradiol was not determined in any samples. Additionally in all extracts, mushroom sterols (ergosterol peroxide and ergosterol) were determined. Their total amounts were significantly lower in samples containing the abovementioned steroids than in extracts from mycelium L. edodes without the addition of steroid hormones. The results demonstrated that the mycelium of L. edodes can be used in the biodegradation process of a water environment contaminated with endocrine disruptors. PMID- 30298117 TI - A Single-Chain-Based Hexavalent CD27 Agonist Enhances T Cell Activation and Induces Anti-Tumor Immunity. AB - Tumor necrosis factor receptor superfamily member 7 (TNFRSF7, CD27), expressed primarily by T cells, and its ligand CD27L (TNFSF7, CD70) provide co-stimulatory signals that boost T cell activation, differentiation, and survival. Agonistic stimulation of CD27 is therefore a promising therapeutic concept in immuno oncology intended to boost and sustain T cell driven anti-tumor responses. Endogenous TNFSF/TNFRSF-based signal transmission is a structurally well-defined event that takes place during cell-to-cell-based contacts. It is well-established that the trimeric-trivalent TNFSF-receptor binding domain (TNFSF-RBD) exposed by the conducting cell and the resulting multi-trimer-based receptor clustering on the receiving cell are essential for agonistic signaling. Therefore, we have developed HERA-CD27L, a novel hexavalent TNF receptor agonist (HERA) targeting CD27 and mimicking the natural signaling concept. HERA-CD27L is composed of a trivalent but single-chain CD27L-receptor-binding-domain (scCD27L-RBD) fused to an IgG1 derived silenced Fc-domain serving as dimerization scaffold. The hexavalent agonist significantly boosted antigen-specific T cell responses while having no effect on non-specific T cells and was superior over stabilized recombinant trivalent CD27L. In addition, HERA-CD27L demonstrated potent single agent anti-tumor efficacy in two different syngeneic tumor models, MC38-CEA and CT26wt. Furthermore, the combination of HERA-CD27L and an anti-PD-1 antibody showed additive anti-tumor effects highlighting the importance of both T cell activation and checkpoint inhibition in anti-tumor immunity. In this manuscript, we describe the development of HERA-CD27L, a true CD27 agonist with a clearly defined forward-signaling mechanism of action. PMID- 30298119 TI - Preclinical Evaluation of White Led-Activated Non-porphyrinic Photosensitizer OR141 in 3D Tumor Spheroids and Mouse Skin Lesions. AB - Photodynamic therapy (PDT) is used to treat malignancies and precancerous lesions. Near-infrared light delivered by lasers was thought for a while to be the most appropriate option to activate photosensitizers, mostly porphyrins, in the depth of the diseased tissues. More recently, however, several advantages including low cost and reduced adverse effects led to consider light emitting diodes (LED) and even daylight as an alternative to use PDT to treat accessible lesions. In this study we examined the capacity of OR141, a recently identified non-porphyrin photosensitizer (PS), to exert significant cytotoxic effects in various models of skin lesions and tumors upon white light activation. Using different cancer cell lines, we first identified LED lamp as a particularly suited source of light to maximize anti-proliferative effects of OR141. We then documented that OR141 diffusion and light penetration into tumor spheroids both reached thresholds compatible with the induction of cell death deep inside these 3D culture models. We further identified Arlasove as a clinically suitable solvent for OR141 that we documented by using Franz cells to support significant absorption of the PS through human skin. Finally, using topical but also systemic administration, we validated growth inhibitory effects of LED-activated OR141 in mouse skin tumor xenograft and precancerous lesions models. Altogether these results open clinical perspectives for the use of OR141 as an attractive PS to treat superficial skin malignant and non-malignant lesions using affordable LED lamp for photoactivation. PMID- 30298118 TI - New Frontiers for the Cytoskeletal Protein LASP1. AB - In the recent two decades, LIM and SH3 protein 1 (LASP1) has been developed from a simple actin-binding structural protein to a tumor biomarker and subsequently to a complex, nuclear transcriptional regulator. Starting with a brief historical perspective, this review will mainly compare and contrast LASP1 and LASP2 from the angle of the newest data and importantly, examine their role in transcriptional regulation. We will summarize the current knowledge through pictorial models and tables including the roles of different microRNAs in the differential regulation of LASP1 levels and patient outcome rather than specify in detail all tumor entities. Finally, the novel functional roles of LASP1 in secretion of vesicles, expression of matrix metalloproteinases and transcriptional regulation as well as the activation of survival and proliferation pathways in different cancer types are described. PMID- 30298120 TI - Mevalonate Metabolism in Cancer Stemness and Trained Immunity. AB - Mevalonate metabolism provides cancer and immune cells with diverse products to ensure cell functionality. Similar metabolic reprogramming that raises mevalonate metabolism to higher levels appears to drive both, epithelial mesenchymal transition (EMT) of cancer cells, a reverse differentiation program that generates cancer cells with stem cell properties, and immune cell training for increased responsiveness to secondary stimulation. In this review, we address how mevalonate metabolism supports cancer development and stemness on the one hand, and on the other promotes immune responsiveness. In view of this dual nature of mevalonate metabolism, strategies to manipulate this metabolic pathway as part of anti-cancer therapies require careful analysis of risks versus benefits. PMID- 30298122 TI - Prevalence of Yersinia Species in the Ileum of Crohn's Disease Patients and Controls. AB - Yersinia are common contaminants of food products, but their prevalence in the human gut is poorly documented. Yersinia have been implicated in Crohn's Disease (CD, an inflammatory bowel disease) however their role in CD is controversial. We performed highly sensitive PCR assays of specific sequences for the gyrB gene of Y. aldovae, Y. bercovieri, Y. enterocolitica, Y. intermedia, Y. mollaretii and the inv gene of Y. pseudotuberculosis. We analyzed a total of 470 ileal samples taken from 338 participants (262 CD patients and 76 controls) belonging to three independent cohorts. All patients and controls were phenotyped and genotyped for the main CD susceptibility variants: NOD2, ATG16L1, and IRGM. Yersinia were found in 7.7% of ileal samples (respectively 7.9 and 7.6% in controls and CD patients) corresponding to 10% of participants (respectively 11.8 and 9.5% in controls and CD patients). Y. enterocolitica, Y. pseudotuberculosis and Y. intermedia were the most frequently identified species. The bacteria were more frequent in resected specimens, lymph nodes and Peyer's patches. Yersinia were no more likely to be detected in CD tissues than tissues from inflammatory and non-inflammatory controls. CD patients treated with immunosuppressants were less likely to be Yersinia carriers. In conclusion, this work shows that Yersinia species are frequently found at low levels in the human ileum in health and disease. The role of Yersinia species in this ecosystem should now be explored. PMID- 30298121 TI - Translational Potential of Therapeutics Targeting Regulatory Myeloid Cells in Tuberculosis. AB - Despite recent advances in tuberculosis (TB) drug development and availability, successful antibiotic treatment is challenged by the parallel development of antimicrobial resistance. As a result, new approaches toward improving TB treatment have been proposed in an attempt to reduce the high TB morbidity and mortality rates. Host-directed therapies (HDTs), designed to modulate host immune components, provide an alternative approach for improving treatment outcome in both non-communicable and infectious diseases. Many candidate immunotherapeutics, designed to target regulatory myeloid immune components in cancer, have so far proven to be of value as repurposed HDT in TB. Several of these studies do however lack detailed description of the mechanism or host pathway affected by TB HDT treatment. In this review, we present an argument for greater appreciation of the role of regulatory myeloid cells, such as myeloid-derived suppressor cells (MDSC), as potential targets for the development of candidate TB HDT compounds. We discuss the role of MDSC in the context of Mycobacterium tuberculosis infection and disease, focussing primarily on their specific cellular functions and highlight the impact of HDTs on MDSC frequency and function. PMID- 30298123 TI - Osteogenic Sarcoma in an Adolescent With Cystic Fibrosis: Successful Treatment Despite Significant Obstacles. AB - Introduction: We describe the case of a 16-year old male with cystic fiborosis (CF) who presented with an osteosarcoma of his right distal tibia. Case Report: Treatment consisted of neoadjuvant chemotherapy of cisplatin, doxorubicin and high dose methotrexate followed by distal tibial resection and free fibula flap reconstruction and consolidation chemotherapy. Treatment was complicated by a pulmonary exacerbation, where Pseudomonas aeruginosa (PsA) and Staphylococcus aureus were grown on sputum culture which was treated with a 2-week course of intravenous piptazobactam and tobramycin. Mycobacterium intracellulare and Mycobacterium abscessus were also cultured following commencement of chemotherapy and successfully treated with a 6-month course of oral azithromycin, ethambutol, and moxifloxacin along with a 1-month course of inhaled amikacin. Pulmonary function improved during his treatment from baseline FEV1 of 3.8 l (93.9%) to 4.15 l (102.3% predicted) whilst nutritional status remained stable. Discussion: The combination of CF and osteosarcoma is rare with only one previous case reported (1). Our case is instructive as the patient faced the challenge of chronic PsA and the first reported culturing and successful treatment of non tuberculous mycobacterium (NTM) during chemotherapy. Fatal outcomes have been reported previously for CF patients during immunosuppression (2). In concordance with our findings, a recent report noted an improvement in respiratory function in a child treated for leukemia (3). The anti-inflammatory nature of some chemotherapy agents could be responsible for the observed clinical improvement in CF with low dose methotrexate having been shown to increase FEV1 in adolescents with advanced CF (4). Whilst doxorubicin could improve pulmonary outcomes through increased total cellular CFTR protein expression and CFTR associated chloride secretion (5). It is hypothesized that the improved pulmonary function in patients with CF who require chemotherapy could be due to increased production of Multi-Drug Resistance Proteins (MDR) and Multi-Drug Resistant Associated Proteins (MRP) that may complement the depleted CFTR protein (6). Concluding Remarks: We report the well-tolerated management of osteosarcoma in a patient with CF including the first reported identification and eradication of NTM during chemotherapy. The observed positive pulmonary outcome following chemotherapy highlights several potential cellular mechanisms that deserve to be explored. PMID- 30298124 TI - Classification of Pediatric Asthma: From Phenotype Discovery to Clinical Practice. AB - Advances in big data analytics have created an opportunity for a step change in unraveling mechanisms underlying the development of complex diseases such as asthma, providing valuable insights that drive better diagnostic decision-making in clinical practice, and opening up paths to individualized treatment plans. However, translating findings from data-driven analyses into meaningful insights and actionable solutions requires approaches and tools which move beyond mining and patterning longitudinal data. The purpose of this review is to summarize recent advances in phenotyping of asthma, to discuss key hurdles currently hampering the translation of phenotypic variation into mechanistic insights and clinical setting, and to suggest potential solutions that may address these limitations and accelerate moving discoveries into practice. In order to advance the field of phenotypic discovery, greater focus should be placed on investigating the extent of within-phenotype variation. We advocate a more cautious modeling approach by "supervising" the findings to delineate more precisely the characteristics of the individual trajectories assigned to each phenotype. Furthermore, it is important to employ different methods within a study to compare the stability of derived phenotypes, and to assess the immutability of individual assignments to phenotypes. If we are to make a step change toward precision (stratified or personalized) medicine and capitalize on the available big data assets, we have to develop genuine cross-disciplinary collaborations, wherein data scientists who turn data into information using algorithms and machine learning, team up with medical professionals who provide deep insights on specific subjects from a clinical perspective. PMID- 30298125 TI - Probing the Origins of 1,800 MHz Radio Frequency Electromagnetic Radiation Induced Damage in Mouse Immortalized Germ Cells and Spermatozoa in vitro. AB - As the use of mobile phone devices is now highly prevalent, many studies have sought to evaluate the effects of the radiofrequency-electromagnetic radiation (RF-EMR) on both human health and biology. While several such studies have shown RF-EMR is capable of inducing cellular stress, the physicobiological origin of this stress remains largely unresolved. To explore the effect of RF-EMR on the male reproductive system, we exposed cultured mouse spermatogonial GC1 and spermatocyte GC2 cell lines, as well as cauda epididymal spermatozoa to a waveguide generating continuous wave RF-EMR (1.8 GHz, 0.15 and 1.5 W/kg). This study demonstrated that a 4 h exposure is capable of inducing the generation of mitochondrial reactive oxygen species (ROS) in populations of GC1 (7 vs. 18%; p < 0.001) and GC2 cells (11.5 vs. 16 %; p < 0.01), identifying Complex III of the electron transport chain (ETC) as the potential source of electrons producing ROS. Assessing the generation of ROS in the presence of an antioxidant, penicillamine, as well as measuring lipid peroxidation via 4-hydroxynonenal levels, indicated that the elevated incidence of ROS generation observed under our exposure conditions did not necessarily induce an overt cellular oxidative stress response. However, exposure to RF-EMR at 0.15 W/kg for 3 h did induce significant DNA fragmentation in spermatozoa (that was no longer significant after 4 h), assessed by the alkaline comet assay (p < 0.05). Furthermore, this fragmentation was accompanied by an induction of oxidative DNA damage in the form of 8-hydroxy-2'-deoxyguanosine, which was significant (p < 0.05) after spermatozoa were exposed to RF-EMR for 4 h. At this exposure time point, a decline in sperm motility (p < 0.05) was also observed. This study contributes new evidence toward elucidating a mechanism to account for the effects of RF-EMR on biological systems, proposing Complex III of the mitochondrial ETC as the key target of this radiation. PMID- 30298126 TI - Successful Curriculum Change in Health Management and Leadership Studies for the Specialist Training Programs in Medicine in Finland. AB - In Finland, the specialization programs in Medicine and Dentistry can be undertaken at all five university medical faculties in 50 specialization programs and in five programs for Dentistry. The specialist training requires 5 or 6 years (300-360 ECTS credits) of medical practice including 9 months of service in primary health care centers, theoretical substance specific education, management studies, and passing a national written exam. The renovation of the national curriculum for the specialization programs was implemented, first in 2008 and officially in August 2009, when theoretical multi-professional social, health management and leadership studies (10-30 ECTS credits) were added to the curriculum. According to European Credit Transfer and Accumulation System (ECTS), 1 ECTS credit (henceforth, simply "ECTS") means 27-30 h of academic work National guidelines for the multi-professional leadership training include the basics of organizational management and leadership, the social and healthcare system, human resources (HR) management, leadership interaction and organizational communication, healthcare economy, legislation (HR) and data management. Each medical faculty has implemented management studies autonomously but according to national guidelines. This paper will describe how the compulsory management studies (10 ECTS) have been executed at the Universities of Tampere and Turku. In Tampere, the 10 ECTS management studies follow a flexible design of six academic modules. Versatile modern teaching methods such as technology-assisted and student orientated learning are used. Advanced supplementary management studies (20 ECTS) are also available. In Turku, the 10 ECTS studies consist of academic lectures, portfolio and project work. Attendees select contact studies (4-6 ECTS) from yearly available 20 ECTS and proceed at their own pace. Portfolio and project comprise 2-5 ECTS each. The renovation of medical specializing physicians' management and leadership education has been a successful reform. It has been observed that positive attitudes and interest toward management overall are increasing among younger doctors. In addition, management and leadership education will presumably facilitate medical doctors' work as managers also. Continuous development of medical doctors' management and leadership education for physicians and dentists is needed while the changing and complex healthcare environment requires both professional and leadership expertise. PMID- 30298127 TI - Protected and De-protected Platinum(IV) Glycoconjugates With GLUT1 and OCT2 Mediated Selective Cancer Targeting: Demonstrated Enhanced Transporter-Mediated Cytotoxic Properties in vitro and in vivo. AB - Physiological characteristics of human malignancies are increased glycolysis and overexpression of glucose transporters (GLUTs). 18Flurodeoxyglucose-positron emission tomography (FDG-PET) has successfully developed as clinical modality for the diagnosis and staging of many cancers based on the Warburg effect. To leverage this glucose transporter mediated metabolic disparity between normal and malignant cells, in the current report, protected, and de-protected glucose, mannose, galactose, rhamnose, maltose, and lactose-conjugated platinum(IV) complexes were designed and synthesized. The suggested potential of facilitated intravenous to oral switching of glycosylated platinum(IV) prodrugs with cancer targeting properties were evaluated for glucose transporter 1 (GLUT1) and organic cation transporter 2 (OCT2)-mediated selective properties in vitro and in vivo. The cytotoxicity of 2d, 5d, and 6d were ~23-fold greater than that of the positive controls cisplatin, oxaliplatin, and satraplatin, respectively. The leading compound 6d, the IC50 of which with the GLUT1 inhibitor 4,6-oethylidene alpha-D-glucose (EDG) and phloretin (31.80 and 38.71 MUM) are 36- and 44-folds higher, respectively, than the 48 h IC50 (0.89 MUM), is superior to the reported 5-8, exhibiting enhanced cancer targeting. The compounds also showed reduced toxicity to normal cells (293T IC50 = 12.06 MUM and 3T3 cells IC50 > 100 MUM) and exhibited no cross-resistance to cisplatin. Moreover, the encouraging selectivity of 6d for MCF-7 cells in vivo indicated that the pyranoside performs an important function in cancer targeting. PMID- 30298128 TI - Electrocatalysis of Lindane Using Antimony Oxide Nanoparticles Based-SWCNT/PANI Nanocomposites. AB - This work describes the chemical synthesis of antimony oxide nanoparticles (AONPs), polyaniline (PANI), acid functionalized single-walled carbon nanotubes (fSWCNTs), and the nanocomposite (AONP-PANI-SWCNT) as catalyst for the trace detection of lindane. Successful synthesis of the nanomaterials was confirmed by Fourier transform infrared (FT-IR) spectroscopy, ultraviolet-visible (UV-Vis) spectroscopy, x-ray diffraction (XRD) spectroscopy, and scanning electron microscopy (SEM). Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were used for investigating the electrochemical behavior of the modified electrodes in the ferrocyanide/ferricyanide ([Fe(CN)6]4-/[Fe(CN)6]3 ) redox probe. GCE-AONP-PANI-SWCNT exhibited faster electron transport properties as well as higher electroactivity as compared to bare-GCE, GCE-AONPs, GCE-PANI, and GCE-SWCNT electrodes. Electrocatalytic studies further showed that GCE-AONP PANI-SWCNT modified electrode was stable (after 20 scans) with only a small current drop in lindane (0.57%). The GCE-AONP-PANI-SWCNT electrode with low detection limit of 2.01 nM performed better toward the detection of lindane as compared to other studies in literature. The GCE-AONP-PANI-SWCNT electrode is highly selective toward the detection of lindane in the presence of various organic and inorganic interfering species. Real sample analysis of river water and tap water samples using the developed sensor gave satisfactory percentage recoveries therefore confirming the potential of the proposed sensor for practical application. PMID- 30298129 TI - Recent Progress in European Advanced Therapy Medicinal Products and Beyond. AB - Cell- and gene-based therapies form one of the pillars of regenerative medicine. They have the potential to transform quality of life and improve the health status of patients with genetic and cellular defects, including genetic diseases, neurodegenerative diseases and tissue malignancies, amongst others. Despite numerous challenges, in the last decade, tremendous unified efforts by research and clinical scientists in academic, translational and industry settings have resulted in tangible outcomes in the form of many marketing authorizations and approved commercial firsts, such as Glybera(r), Kymriah(r), YESCARTA(r), Holoclar(r), and LuxturnaTM. This report presents a succinct analysis of developments in the regenerative medicine landscape, including immuno-oncology, with a focus on the European Union and examples of clinical and commercial successes and failures. The factors that led to these exciting developments in immune-oncology are also considered. Concurrently, several key issues, spanning from the identification of unmet clinical need, associated challenges, economic evaluation to policy improvements are emphasized. Furthermore, industry insights encompassing the five-dimensional research and development framework for the focused development of medicine, pricing and reimbursement issues, technology adoption and permeation of innovative advanced therapy medicinal products in the clinical set up are reflected upon, following elaborate discussions that transpired in different thematic tracks of Tissue Engineering & Regenerative Medicine International Society European Chapter 2017 Industry Symposium.

AB - Antibiotic management of infections with multidrug-resistant organisms (MDRO) represents a complex clinical challenge. We report here the first patient with a severe MDRO infection managed with assistance of a novel "real-time" 3-day high throughput screen (HTS) that allowed screening of 9 drugs in 14 combinations in 2,304 total samplings. Identified synergies were used to modify patient therapy with the goal of reducing drug-induced toxicity. The desired clinical outcome was achieved on the HTS-informed therapeutic regimen, supporting the utility of HTS technology to expand standard antimicrobial susceptibility testing.

AB - We report a fatal bacteremia caused by Klebsiella pneumoniae in a 60-70-year-old patient from Brazil. The genomic analysis of three isolates (from blood culture, nasal and anal swabs) showed that the bacteremia was caused by a KPC-2 producing extensively drug-resistant K64-ST11 hypermucousviscous K. pneumoniae (hmKP) harboring several virulence and antimicrobial resistance genes. Although the isolates did not present virulence markers associated with hypervirulent K. pneumoniae (hvKP), they showed invasion and toxicity to epithelial Hep-2 cells; resistance to cell microbicidal mechanisms; and blood and human serum survival, evidencing their pathogenic potential. This study highlights the risk of infection caused by hmKp strains not characterized as hvKP as well as the clinical implications and difficulty of treatment, especially in elderly or immunocompromised patients. PMID- 30298134 TI - Effect of Floor Cooling on Behavior and Heart Rate of Late Lactation Sows Under Acute Heat Stress. AB - Much U.S. swine production is in Koppen climate types classified as "hot-summer humid continental" and "humid subtropical." As a result, farrowing sows are often exposed to temperatures above their upper critical temperature. This heat stress (HS) can affect sow welfare and productivity and have a negative economic impact. The study objective was to evaluate the impact of a cooling pad on sows' behavioral and heart rate responses to acute HS. Treatments were randomly allotted to ten multiparous sows to receive a constant cool water flow of 0.00 (CONTROL, n = 4), 0.25 (LOW, n = 2), 0.55 (MEDIUM, n = 2), or 0.85 (HIGH, n = 2) L/min for 100 min and replicated eight times, switching treatments so that each sow was exposed to each treatment. The cooling was initiated 1 h after the room reached 35 degrees C for 100 min. Eating, drinking and nursing behaviors, postures, and heart rate were recorded before heating (Period 1), prior to cooling (Period 2), and during cooling (Period 3). There were no differences between LOW, MEDIUM, and HIGH flow rates for any periods on all behavioral and heart rate traits, so data were pooled (COOLED). There were no differences in any of the measures during Periods 1 and 2, except for the ratio of short term to long term heart rate variability (SD1:SD2) with higher values for CONTROL than COOLED sows in Period 2. During Period 3, CONTROL sows changed postures more frequently (11.5 +/-1.6 vs. 5.1 +/-1.6 changes per hour), spent more time drinker pressing/drinking (4.4 +/- 0.5 vs. 1.4 +/- 0.4% of time), standing (6.6 +/- 1.7 vs. 3.8 +/- 1.6% of time), sitting (10.0 +/- 1.2 vs. 4.0 +/- 1.1), less time lying (83.0 +/-1.8 vs. 92.0 +/-1.7% of time), especially lying laterally (62.0 +/ 5.6 vs. 75.0 +/- 5.3% of time), than sows in all three cooling treatments (all P < 0.001). Heart rate during Period 3 was lower for COOLED sows compared to the CONTROL sows (100.2 +/- 3.4 vs. 119.0 +/- 4.0 beat per min, P < 0.001). Sows response to increased thermal load can be effectively reduced using water-cooled cooling pads, thereby improving sow comfort and welfare. The beneficial effects on behavior are noticeable from the lowest flow rate. PMID- 30298130 TI - Pathophysiology of Trans-Synaptic Adhesion Molecules: Implications for Epilepsy. AB - Chemical synapses are specialized interfaces between neurons in the brain that transmit and modulate information, thereby integrating cells into multiplicity of interacting neural circuits. Cell adhesion molecules (CAMs) might form trans synaptic complexes that are crucial for the appropriate identification of synaptic partners and further for the establishment, properties, and dynamics of synapses. When affected, trans-synaptic adhesion mechanisms play a role in synaptopathies in a variety of neuropsychiatric disorders including epilepsy. This review recapitulates current understanding of trans-synaptic interactions in pathophysiology of interneuronal connections. In particular, we discuss here the possible implications of trans-synaptic adhesion dysfunction for epilepsy. PMID- 30298133 TI - The Role of Polyphenols in Human Health and Food Systems: A Mini-Review. AB - This narrative mini- review summarizes current knowledge of the role of polyphenols in health outcomes-and non-communicable diseases specifically-and discusses the implications of this evidence for public health, and for future directions for public health practice, policy, and research. The publications cited originate mainly from animal models and feeding experiments, as well as human cohort and case-control studies. Hypothesized protective effects of polyphenols in acute and chronic diseases, including obesity, neurodegenerative diseases, type 2 diabetes, and cardiovascular diseases, are evaluated. Potential harmful effects of some polyphenols are also considered, counterbalanced with the limited evidence of harm in the research literature. Recent international governmental regulations are discussed, as the safety and health claims of only a few specific polyphenolic compounds have been officially sanctioned. The implications of food processing on the bioavailability of polyphenols are also assessed, in addition to the health claims and marketing of polyphenols as a functional food. Finally, this mini-review asserts the need for increased regulation and guidelines for polyphenol consumption and supplementation in order to ensure consumers remain safe and informed about polyphenols.

AB - Microbubbles magnify the acoustic pressure of low-intensity pulsed ultrasound (LIPUS) and may enhance its bioeffect for diagnostic and therapeutic purposes. This study compared the effect of this novel microbubble-mediated ultrasound (MUS) with that of the traditional LIPUS on osteogenesis and neovascularization in a rabbit model of steroid-associated osteonecrosis. We hypothesized that MUS might outweigh LIPUS on promoting osteogenesis and neovascularization in steroid associated osteonecrosis. The bilateral femoral head necrosis was induced by lipopolysaccharide and methylprednisolone in the rabbits. The indices of bone mineral density (BMD), trabecular number, maximal loading strength, and mineral apposition rate were analyzed, demonstrating that the animal model of steroid associated osteonecrosis was successfully established. Both the MUS group (GM) and the LIPUS group (GL) were insonated 20 min daily for six weeks. GM received an extra intracapsular injection of microbubbles before insonation every other day. Fluorescence bone labeling, Micro-CT Analysis, biomechanical test, quantitative real-time PCR, Western blot analysis, and histological evaluation were performed for comparing GM with GL. The results demonstrated a 39% higher mineral apposition rate in GM compared with GL. The BMD and the maximal loading strength of femoral head of GM increased by 4.3% and 27.8% compared to those of GL, respectively. The mRNA and protein expression of BMP-2 and VEGF were also significantly higher in GM. The number of blood vessels of GM was 65% greater than that of GL. MUS is more potent than LIPUS in enhancing osteogenesis, neovascularization, and biomechanical strength of femoral head in the animal model of steroid-associated osteonecrosis. Without increasing the intensity of insonation or the risk of tissue damage, MUS is better for inhibiting the process of steroid-associated osteonecrosis. PMID- 30298136 TI - The Antimicrobial Peptide Nal-P-113 Exerts a Reparative Effect by Promoting Cell Proliferation, Migration, and Cell Cycle Progression. AB - Objective: The primary purpose of this study was to evaluate the reparative efficacy of a novel antimicrobial peptide, Nal-P-113, in shortening the healing time of oral mucosal ulcers by promoting cell proliferation and migration and accelerating the cell cycle. Methods: Cell counting kit-8 (CCK-8) and wound healing assays were used to evaluate the proliferation and migration of human immortalized oral epithelial cells (HIOECs). The cell cycle distribution of HIOECs was analyzed by flow cytometry. Additionally, the RNA levels of EGF, FGF 2, and TGF-beta1 of HIOECs were assessed by real-time PCR. Rats were divided into three groups randomly: (a) blank control group; (b) 20 MUg/mL Nal-P-113; and (c) 10 ng/mL rhEGF. An oral mucosal ulcer was induced in every rat by the application of 30% acetic acid. An immunohistochemical assay was used to assess the expression of EGF, FGF-2, and TGF-beta1 in the rat oral mucosa. Results: In the CCK-8 assay, the optical density values in the Nal-P-113 and rhEGF groups were found to be significantly higher than that in the blank control group. In addition, the scratch areas in the Nal-P-113 and rhEGF groups were found to be significantly smaller (P<0.05). Cell cycle analysis showed that Nal-P-113 accelerated the entry of HIOECs into the S phase and expedited their cell cycles. The RT-PCR results suggested that Nal-P-113 upregulated the RNA levels of EGF and FGF-2 but downregulated that of TGF-beta1 at 24 h and 48 h. Lastly, the immunohistochemical assay verified that Nal-P-113 changed the expression of the above cytokines in rat mucosal ulcers. Conclusion: Nal-P-113 promoted the repair of oral mucosal ulcers by increasing the EGF and FGF-2 expression and decreasing that of TGF-beta1 in HIOECs, accelerating their proliferation and cell cycle progression. The application of Nal-P-113 might serve as an effective therapeutic approach for recurrent aphthous stomatitis. PMID- 30298137 TI - Identification of Genetic Risk Factors for Neonatal Hyperbilirubinemia in Fujian Province, Southeastern China: A Case-Control Study. AB - To date, the genetic risk factors for neonatal hyperbilirubinemia remain unknown in Southeastern China. This case-control study aimed to identify the genetic risk factors for neonatal hyperbilirubinemia in Fujian, Southeastern China. A total of 286 hyperbilirubinemic newborns were enrolled as a case group, and 250 randomly selected newborns without jaundice or with a bilirubin level that was lower than the threshold required for phototherapy served as controls. The serum levels of total bilirubin, unconjugated bilirubin, and direct bilirubin were measured, and the common genetic loci in UGT1A1, OATP1B1, and HO-1 genes were genotyped. Higher incidence of ABO incompatibility and G6PD deficiency was detected in the case group compared to the control group (P < 0.01). There were significant differences in the frequencies of rs4148323 and rs1805173 genotypes between the case and control groups (P < 0.05). At the rs4148323 locus, the frequencies of GA heterozygotes and AA mutant homozygotes were higher in the case group than in the control group (P < 0.05), and at the rs1805173 locus, the frequencies of LS, MS, and SS genotypes were higher in the case group than in the control group (P < 0.05). A higher frequency of rs4148323 A allele and rs1805173 S allele was detected in the case group compared to the control group (P = 0). Additionally, multivariate logistic regression analysis identified that the mutant genotype of rs4148323 in the UGT1A1 gene, ABO incompatibility, G6PD deficiency, and SS genotype at rs1805173 locus of the HO-1 gene were genetic risk factors of neonatal hyperbilirubinemia. Our data demonstrate that G211 mutation in the UGT1A1 gene, ABO incompatibility, G6PD deficiency, and the SS genotype of the repeats in the promoter region of the HO-1 gene are risk factors for neonatal hyperbilirubinemia in Fujian, Southeastern China. PMID- 30298138 TI - Inflammatory-Driven Angiogenesis in Bone Augmentation with Bovine Hydroxyapatite, B-Tricalcium Phosphate, and Bioglasses: A Comparative Study. AB - Introduction: The clinical use of bioactive materials for bone augmentation has remained a challenge because of predictability and effectiveness concerns, as well as increased costs. The purpose of this study was to analyse the ability to integrate bone substitutes by evaluating the immunohistochemical expression of the platelet endothelial cell adhesion molecules, vascular endothelial growth factor, collagen IV, laminin, and osteonectin, in the vicinity of bone grafts, enabling tissue revascularization and appearance of bone lamellae. There is a lack of in vivo studies of inflammatory-driven angiogenesis in bone engineering using various grafts. Methods: The study was performed in animal experimental model on the standardized monocortical defects in the tibia of 20 New Zealand rabbits. The defects were augmented with three types of bone substituents. The used bone substituents were beta-tricalcium phosphate, bovine hydroxyapatite, and bioactive glasses. After a period of 6 months, bone fragments were harvested for histopathologic examination. Endothelial cell analysis was done by analysing vascularization with PECAM/CD31 and VEGF and fibrosis with collagen IV, laminin, and osteonectin stains. Statistical analysis was realized by descriptive analysis which was completed with the kurtosis and skewness as well as the Kruskal-Wallis and Mann-Whitney statistical tests. Results: The discoveries show that the amount of bone that is formed around beta-tricalcium phosphate and bovine hydroxyapatite is clearly superior to the bioactive glasses. Both the lumen diameter and the number of vessels were slightly increased in favor of beta-tricalcium phosphate. Conclusion: We can conclude that bone substitutes as bovine bone and beta tricalcium phosphate have significant increased angiogenesis (and subsequent improved osteogenesis) compared to the bioactive glass. In our study, significant angiogenesis is linked with a greater tissue formation, indicating that in bone engineering with the allografts we used, inflammation has more benefic effects, the catabolic action being exceeded by the tissue formation. PMID- 30298139 TI - Spatially-Compact MR-Guided Kernel EM for PET Image Reconstruction. AB - Positron emission tomography (PET) is a highly sensitive functional and molecular imaging modality which can measure picomolar concentrations of an injected radionuclide. However, the physical sensitivity of PET is limited, and reducing the injected dose leads to low count data and noisy reconstructed images. A highly effective way of reducing noise is to reparameterise the reconstruction in terms of MR-derived spatial basis functions. Spatial basis functions derived using the kernel method have demonstrated excellent noise reduction properties and maintain shared PET-MR detailed structures. However, as previously shown in the literature, the MR-guided kernel method may lead to excessive smoothing of structures that are only present in the PET data. This work makes two main contributions in order to address this problem: first, we exploit the potential of the MR-guided kernel method to form more spatially-compact basis functions which are able to preserve PET-unique structures, and secondly, we consider reconstruction at the native MR resolution. The former contribution notably improves the recovery of structures which are unique to the PET data. These adaptations of the kernel method were compared to the conventional implementation of the MR-guided kernel method and also to MLEM, in terms of ability to recover PET unique structures for both simulated and real data. The spatially-compact kernel method showed clear visual and quantitative improvements in the reconstruction of the PET unique structures, relative to the conventional kernel method for all sizes of PET unique structures investigated, whilst maintaining to a large extent the impressive noise mitigating and detail preserving properties of the conventional MR-guided kernel method. We therefore conclude that a spatially-compact parameterisation of the MR-guided kernel method, should be the preferred implementation strategy in order to obviate unnecessary losses in PET unique details. PMID- 30298140 TI - Maternal Plasma Concentrations of Per- and polyfluoroalkyl Substances and Breastfeeding Duration in the Norwegian Mother and Child Cohort. AB - Background: Per- and polyfluoroalkyl substances (PFASs) have been widely produced, many of them persist in the environment, and have been associated with various health effects. Previous studies have identified inverse associations between perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS) and breastfeeding duration, but have been limited in investigation of other PFASs. Methods: We measured the associations between plasma concentrations of 9 different PFASs and cessation of breastfeeding before 3 and 6 complete months using women from the Norwegian Mother and Child Cohort Study (MoBa). The study population includes 1716 primarily nulliparous women from two previous studies of MoBa participants, enrolled from 2003-2007. The association was measured using Cox proportional hazards model. Mixtures analyses were performed using Elastic net regularization to identify interactive effects and control for co-pollutant confounding. Results: Concentrations of PFASs in this population were lower than concentrations in the previous studies on this topic. We found associations between increasing concentrations of perfluorononanoic acid (PFNA), perfluorodecaconic acid (PFDA), perfluoroundecanoic acid (PFUnDA) and decreased breastfeeding cessation (increased duration). The strongest associations were seen between PFDA and PFUnDA and cessation before 3 months: (both hazard ratios = 0.73, 95% confidence intervals: 0.62, 0.86). In our population, the other PFASs appeared to be unassociated with breastfeeding cessation. The mixtures analyses identified meaningful interactions between PFUnDA:PFDA, perfluorohexane sulfonate (PFHXS):PFOA and PFOA:PFOS. Conclusions: The identification of associations between previously unexamined PFASs concentrations and increased breastfeeding duration is novel and may be explained by differences in transplacental transfer rates. PMID- 30298141 TI - MoodLight: Exploring Personal and Social Implications of Ambient Display of Biosensor Data. AB - MoodLight is an interactive ambient lighting system that responds to biosensor input related to an individual's current level of arousal. Changes in levels of arousal correspond to fluctuations in the color of light provided by the system, altering the immediate environment in ways intimately related to the user's private internal state. We use this intervention to explore personal and social implications of the ambient display of biosensor data. This study provides greater understanding of the ways in which the representations of personal informatics, with a focus on ambient feedback, influence our perceptions of ourselves and those around us. PMID- 30298142 TI - Alcohol and Marijuana use in Undergraduate Males: Between- and Within-Person Associations with Interpersonal Conflict. AB - Background: Among college students, interpersonal conflict with others is a common, yet stressful negative interpersonal experience. Research suggests that drinking episodes may contribute to the occurrence of conflict. Marijuana use, independently or in conjunction with alcohol, may also influence the likelihood of subsequent conflict. Objectives: We considered the temporal effects of independent and simultaneous alcohol and marijuana use episodes on the occurrence of interpersonal conflict. Use of multilevel modeling allowed us to distinguish the within-person effects of substance use from between-person differences in frequency of use. Methods: Within a sample of 427 college freshman males over 56 days of daily reports, we examined the independent and interactive effects of episodes of alcohol and marijuana on the odds of conflict within the next 1-, 2-, 3-, and 4 hours. Results: Multilevel modeling analyses showed that drinking episodes increased the likelihood of conflict occurring within the next 1, 2, 3, and 4 hours. Marijuana had weaker positive effects, significant only within the 2 hour window. There were no alcohol by marijuana interaction effects in any analysis. Conclusions/Importance: Both marijuana and alcohol independently increased the likelihood of interpersonal conflict; however, the marijuana effect appeared less robust. As marijuana use becomes more normative and accessible for college students, it is important to understand the extent to which marijuana use results in negative consequences and the contexts under which these effects unfold.

AB - A series of optically active helical poly[(S)-2-ethynyl-N-aliphatic acylpyrrolidine] were efficiently synthesized from a commercially available biomass-based starting material, and that bearing a short propionyl substituent exhibited an unexpected lower critical solution temperature in an aqueous solution with a narrow phase-transition window and a small hysteresis. PMID- 30298144 TI - Development of a biomimetic liver tumor-on-a-chip model based on decellularized liver matrix for toxicity testing. AB - Cancer poses a great health threat to both developed and developing countries, and anti-cancer drugs are of important interest for improved clinical outcomes. Although tumor-on-a-chip technologies offer a feasible approach to screening drug toxicity, their capability to mimic the native tumor microenvironment (TME) is still limited. For better mimicry of the TME, we developed a biomimetic three dimensional (3D) liver tumor-on-a-chip with the integration of essential components derived from decellularized liver matrix (DLM) with gelatin methacryloyl (GelMA) in a microfluidics-based 3D dynamic cell culture system. The biomimetic liver tumor-on-a-chip based on the integration of DLM components with GelMA, as opposed to GelMA only, had an increased capability to maintain cell viability and to enhance hepatocyte functions under flow conditions. The improved performance of the DLM-GelMA-based tumor-on-a-chip may be attributed to the provision of biochemical factors (e.g., growth factors), the preservation of scaffold proteins, and the reestablishment of biophysical cues (e.g., stiffness and shear stress) for better recapitulation of the 3D liver TME. Furthermore, this DLM-GelMA-based tumor-on-a-chip exhibited linear dose-dependent drug responses to the toxicity of acetaminophen and sorafenib. Taken together, our study demonstrates that the DLM-GelMA-based biomimetic liver tumor-on-a-chip better mimics the in vivo TME and holds great promise for a breadth of pathological and pharmacological studies. PMID- 30298145 TI - Binding of the atomic cations hydrogen through argon to water and hydrogen sulfide. AB - Water and hydrogen sulfide will bind with every atomic cation from the first three rows of the periodic table. While some atoms bind more tightly than others, explicitly correlated coupled cluster theory computations show that energy is required to be put into the system in order to dissociate these bonds even for noble gas atoms. The most promising systems have shallow entrance potential energy surfaces (PESs) that lie above deeper wells of a different spin. These wells are shown explicitly for H2OO+, H2SS+, and H2OS+ where relaxed PESs of the heavy atom bond lengths indicate that quartet states will cross more deeply-bound doublet states allowing for relatively easy association but much more difficult dissociation. In astrophysical regions that are cold and diffuse, such associations could lead to the formation of novel molecules utilizing water (or H2S) as the building blocks of more rich subsequent chemistry. Recent work has hypothesized that oxywater (H2OO) may be an intermediate in the formation of molecular oxygen in comets, and this work supports such a conclusion at least from a molecular cation perspective. PMID- 30298146 TI - Photochemical route for synthesizing Co-P alloy decorated ZnIn2S4 with enhanced photocatalytic H2 production activity under visible light irradiation. AB - A series of amorphous Co-P alloy modified ZnIn2S4 composite samples were synthesized through a one-step photochemical method. The as-prepared samples were systematically characterized and the photocatalytic activity for H2 production under visible-light irradiation was investigated. It was found that the Co P/ZnIn2S4 composite samples exhibited higher photocatalytic activity, which is 44 times higher than that of pure ZnIn2S4 and higher than that of the 1 wt% Pt/ZnIn2S4 sample. After modifying with amorphous Co-P alloy, the composite samples showed enhanced photocurrent, reduced photoelectric impedance, weakened fluorescence intensity and extended fluorescence lifetime, which accelerate the separation and transfer of photoinduced charge effectively, thus improving the catalytic activity of the composite sample. This work could provide a new strategy for the design and synthesis of low-cost, high-efficiency composite materials for photocatalytic hydrogen evolution and is promising for energy conversion and utilization. PMID- 30298147 TI - Three-dimensional image based modelling of transport parameters in lithium-sulfur batteries. AB - An elemental sulfur electrode was imaged with X-ray micro and nano computed tomography and segmented into its constituent phases. Morphological parameters including phase fractions and pore and particle size distributions were calculated directly from labelled image data, and flux based simulations were performed to determine the effective molecular diffusivity of the pore phase and electrical conductivity of the conductive carbon and binder phase, Deff and sigmaeff, that can be used as an input for Li-S battery modelling. In addition to its crucial role in providing electrical conductivity within the sulfur electrode, the intrinsic porosity of the carbon binder domain was found to significantly influence Li-ion transport within the electrode. Neglecting this intrinsic porosity results in an overestimation of the electrical conductivity within the sulfur electrode, and an underestimation of the tortuosity of the Li ion conducting phase by ca. 56%. The derivation of effective transport parameters directly from image data may aid in the development of more realistic models of Li-S battery systems by reducing the reliance on empirical correlations, and the uncertainties arising from assumptions made in these correlations.

PMID- 30298150 TI - A novel mitochondrial-targeting near-infrared fluorescent probe for imaging gamma glutamyl transpeptidase activity in living cells. AB - gamma-Glutamyl transpeptidase (GGT) plays an essential role in regulating cellular glutathione and cysteine homeostasis, and its abnormal elevation is associated with different diseases including cancers. Here a novel mitochondrial targeting near-infrared fluorescent probe was designed for GGT by conjugating glutamate acid to a newly synthesized amine hemicyanine fluorophore. The fluorescent probe was initially non-emissive due to the formation of an amide bond which destroyed the electronic-donating ability of the amine moiety and disrupted the push-pull structure. GGT-mediated cleavage of the gamma-glutamyl bond regenerated the initial fluorophore with distinct intramolecular charge transfer (ICT) and activated the fluorescence signal. The fluorescent probe displayed a linear relationship to the concentration of GGT in the range of 1.0 90 U L-1, with an estimated limit of detection (LOD) of 0.4 U L-1. Its ability to target and image mitochondrial GGT activity was demonstrated in living cells with high specificity and fast response. We believe our near-infrared fluorescent probe could have great potential in imaging mitochondrial GGT activity and elucidating GGT-associated pathological consequences in living cells and even small animal models.

AB - The design and synthesis of electrocatalysts with controllable active sites are highly desirable for producing hydrogen. Inspired by the experimental realization of two-dimensional metal-organic framework (2D-MOF) nanosheets, a computational screening was performed to find out the optimal single-atom catalysts for the hydrogen evolution reaction (HER) from 36 2D-MOFs composed of transition metal and benzene-like molecular ligands. Through first-principles calculations, six configurations were identified as potential catalysts for the HER with performance comparable to those of Pt-based catalysts due to the near-zero Gibbs free energy and favourable activation barriers originating from their appropriate d-orbital bonding mechanism with atomic hydrogen.

PMID- 30298152 TI - Graphene-silicon-on-insulator (GSOI) Schottky diode photodetectors. AB - Graphene-silicon (GS) Schottky junctions have been demonstrated as an efficient architecture for photodetection. However, the response speed of such devices for free space light detection has so far been limited to 10s-100s of kHz for wavelength lambda >500 nm. Here, we demonstrate GS Schottky junction photodetectors fabricated on a silicon-on-insulator substrate (SOI) with response speeds approaching 1 GHz, attributed to the reduction of the photo-active silicon layer thickness to 10 MUm and with it a suppression of speed-limiting diffusion currents. Graphene-silicon-on-insulator photodetectors (GSOI-PDs) exhibit a negligible influence of wavelength on response speed and only a modest compromise in responsivities compared to GS junctions fabricated on bulk silicon. Noise equivalent-power (NEP) and specific detectivity (D*) of GSOI photodetectors are 14.5 pW and 7.83 * 1010 cm Hz1/2 W-1, respectively, in ambient conditions. We further demonstrate that combining GSOI-PDs with micro-optical elements formed by modifying the surface topography enables engineering of the spectral and angular response. PMID- 30298153 TI - Monitoring of food spoilage by high resolution THz analysis. AB - High resolution rotational Terahertz (THz) spectroscopy has been widely applied to the studies of numerous polar gas phase molecules, in particular volatile organic compounds (VOCs). During the storage of foodstuffs packed under a protective atmosphere, microbial activity will lead to the generation of a complex mixture of trace gases that could be used as food spoilage indicators. Here we have demonstrated that the THz instrumentation presently available provides sufficient sensitivity and selectivity to monitor the generation of hydrogen sulfide (H2S) in the headspace of packed Atlantic salmon (Salmo salar) fillet portions. A comprehensive comparison was made using selective-ion flow tube mass spectrometry (SIFT-MS) in order to validate the THz measurements and the protocol. The detectivity of a range of alternative compounds for this application is also provided, based on the experimental detection limit observed and molecular spectroscopic properties. Molecules like ethanol, methyl mercaptan and ammonia are suitable indicators with the presently available sensitivity levels, while dimethyl sulfide, acetone and butanone may be considered with a sensitivity improvement of 2 orders of magnitude.

AB - A series of CuO/CeM(rod) catalysts doped by transition metals were prepared and systematically characterized. The introduction of Mn and Ti plays a significant role in promoting the catalytic performance of the CuO/CeO2(rod) catalyst for the preferential oxidation of CO in H2-rich gas, while the doping with Zr basically maintains the same catalytic activity and Ni leads to a negative influence. Mn and Ti additives remarkably enrich the formation of defect structures and promote copper ion incorporation into the surface of CeM(rod), which greatly facilitates the generation of strong interfacial copper-ceria interaction in CuO/CeMn(rod) and CuO/CeTi(rod). In addition, CuO/CeMn(rod) possesses excellent surface oxygen mobility at low temperature due to the existence of manganese species with multiple valence states and todorokite species. The Ce-doped perovskite structure (Na0.5Ce0.5TiO3) further adjusts the oxygen vacancy in CuO/CeTi(rod) and anchors copper oxide species with strong interactions. Although a homogeneous solid solution is formed in CeZr(rod) with increased amounts of oxygen vacancies, the interaction between copper and ceria species in the interface of CuO/CeZr(rod) remains the same as with CuO/CeO2(rod). The addition of Ni impairs the dispersion of copper oxide and weakens the copper-ceria interaction, which damages the catalytic performance of CuO/CeNi(rod). PMID- 30298156 TI - Triplet photosensitization mechanism of thymine by an oxidized nucleobase: from a dimeric model to DNA environment. AB - Nucleic acids are constantly exposed to external agents that can induce chemical and photochemical damage. In spite of the great advances achieved in the last years, some molecular mechanisms of DNA damage are not completely understood yet. A recent experimental report (I. Aparici-Espert et al., ACS Chem. Biol. 2018, 13, 542) proved the ability of 5-formyluracil (ForU), a common oxidatively generated product of thymine, to act as an intrinsic sensitizer of nucleic acids, causing single strand breaks and cyclobutane pyrimidine dimers in plasmid DNA. In the present contribution, we use theoretical methodologies to study the triplet photosensitization mechanism of thymine exerted by ForU in a model dimer and in DNA environment. The photochemical pathways in the former system are described combining the CASPT2 and TD-DFT methods, whereas molecular dynamics simulations and QM/MM calculations are employed for the DNA duplex. It is unambiguously shown that the 1n,pi* state localised in ForU mediates the population of the triplet manifold, most likely the 3pi,pi* state centred in ForU, whereas the 3pi,pi* state localized in thymine can be populated via triplet-triplet energy transfer given the small energy barrier of <0.23 eV determined for this pathway.

AB - Owing to their outstanding performances in molecular recognition, antibodies are extensively used in research and applications in molecular biology, biotechnology and medicine. Recent advances in experimental and computational methods are making it possible to complement well-established in vivo (first generation) and in vitro (second generation) methods of antibody discovery with novel in silico (third generation) approaches. Here we describe the principles of computational antibody design and review the state of the art in this field. We then present Modular, a method that implements the rational design of antibodies in a modular manner, and describe the opportunities offered by this approach.

AB - Currently, porous polymers are mainly synthesized by linking coordination or organic covalent bonds. In this study, we propose the synthesis of a porous coordination/covalent hybridized polymer from di(4-vinylpyridine)-dichloro-zinc (ZnVP2) by "coordination-polymerization" method. The resulting porous polymer demonstrated CO2 capture ability and multi-responsive properties. PMID- 30298159 TI - Expeditious synthesis of multisubstituted indoles via multiple hydrogen transfers. AB - Described herein is the expeditious construction of multi-substituted indole skeletons via multiple hydrogen transfers. When ortho-amino ketoesters were treated with a catalytic amount of TiCl4 in the presence of 1.0 equivalent of dehydrating reagent, three types of hydrogen transfer processes ([1,5]-hydride shift, proton transfer, and [1,2]-hydride shift) occurred to give various 3 alkoxycarbonylindoles. Further study revealed that a [1,2]-alkyl shift instead of a [1,2]-hydride shift proceeded to afford 3-alkylindoles from the substrates with an amino group having tertiary carbons adjacent to a nitrogen atom. PMID- 30298160 TI - QCM detection of molecule-nanoparticle interactions for ligand shells of varying morphology. AB - Nanoparticles (NP) have widespread applications from sensing to drug delivery where much behavior is determined by the nature of the surface and the resulting intermolecular interactions with the local environment. Ligand mixtures enable continuously tunable behavior where both the composition and morphology influence molecular interactions. Mixed ligand shells form multiple morphologies ranging from Janus to patchy and stripe-like with varying domain dimensions. Solvent-NP interactions are generally measured by solubility measures alone. Here we develop a quartz crystal microbalance (QCM) approach to more broadly quantify molecule-NP interactions via vapor phase uptake into solid NP-films independent from solvation constraints. The composition and morphology of mixed ligand shells were found to exhibit pronounced non-monotonic behavior that deviated from continuum thermodynamics, highlighting the influence of ligand morphology upon absorption/adsorption. Alkyl and perfluorinated thiols were used as a model case with constant core-size distribution. The ligand morphology was determined by 19F NMR. Molecule uptake into NPs was measured with five benzene derivatives with varied degree of fluorination. For the cases examined, QCM measurements revealed enhanced uptake for patchy morphologies and suppressed uptake for stripe-like morphologies. These results contrast with insights from solubility measures alone where QCM sometimes identified significant molecular uptake of poor solvents. This QCM method thus provides new insights to molecule-NP interactions independent of the solvation shell. PMID- 30298161 TI - Computational insights into the inhibition of beta-haematin crystallization by antimalarial drugs. AB - During the red blood cell phase of their life cycle, malaria parasites digest their host's haemoglobin, with concomitant release of potentially toxic iron(iii) protoporphyrin IX (FePPIX). The parasites' strategy for detoxification of FePPIX involves its crystallization to haemozoin, such that the build-up of free haem in solution is avoided. Antimalarial drugs of both historical importance and current clinical use are known to be capable of disrupting the growth of crystals of beta haematin, which is the synthetic equivalent of haemozoin. Hence, the disruption of haemozoin crystal growth is implicated as a possible mode of action of such drugs. However, the details of beta-haematin crystal poisoning at the molecular level have yet to be fully elucidated. In this study, we have used a combination of density functional theory (DFT) and molecular modelling to examine the possible modes of action of ten different antimalarial drugs, including quinine type aliphatic alcohols, amodiaquine-type phenols, and chloroquine-type aliphatic diamines. The DFT calculations indicate that each of the drugs can form at least one molecular complex with FePPIX. These complexes have 1 : 1 or 2 : 1 FePPIX : drug stoichiometries and all of them incorporate Fe-O bonds, formed either by direct coordination of a zwitterionic form of the drug, or by deprotonation of water. Most of the drugs can form more than one such complex. We have used the DFT model structures to explore the possible formation of a monolayer of each drug-haem complex on four of the beta-haematin crystal faces. In all cases, the drug complexes can form a monolayer on the fast-growing {001} and {011} faces, but not on the slower growing {010} and {100} faces. Additional modelling of the chloroquine and quinidine complexes shows that individual molecules of these species can also obstruct the growth of new layers on other crystal faces. The implications of these observations for antimalarial drug development are discussed.

AB - We performed a first principle systematic calculation on the adiabatic potential energy curves (PECs) of alkali metal (M = Rb and Cs) - rare gas (Rg = He, Ne, Ar, Kr, and Xe) van der Waals molecules over a wide range of interatomic distance R. All electron basis sets of triple and quadruple zeta valence quality were used for the He, Ne, Ar and Kr atoms. Scalar relativistic effects were taken into account for the heavy Rb, Cs and Xe atoms by means of Dirac-Fock effective core potentials. The correlated ground state energies have been obtained within the framework of the spin unrestricted open-shell coupled cluster method, with perturbative treatment of triple excitations. The electronic energies were corrected for the basis set superposition error (BSSE) using the counterpoise method. Energies were extrapolated to the complete basis set (CBS) limit using a two-point scheme. The energy convergence towards the CBS limit was monitored by the saturation of the dummy atom basis set that included bond functions centered at the midpoint of the interatomic distance. The ab initio point-wise PEC was followed to small R to the point where the energy was 0.5 Hartree above the dissociation limit. A Morse long-range (MLR, UM Rg(R)) potential possessing the correct asymptotic behavior at R -> infinity was fitted to the single point energies. The resulting set of fully analytical MLR potentials was then used to evaluate classical collision integrals over a wide range of collision energies. By this means, diffusion coefficients (DM Rg(T)) were predicted as functions of the translation temperature T <= 3000 K. The reliability of the present ab initio UM Rg(R) and DM Rg(T) functions was accessed through a comparison with previous theoretical and experimental results.

PMID- 30298167 TI - Time to Address "Frailty Creepage" in the Canadian Healthcare System. PMID- 30298168 TI - Implementing Frailty Measures in the Canadian Healthcare System. AB - Canadian healthcare is changing to include individuals living with frailty, but frailty must be better operationalized and better framed by sound data standards and policy. Frailty results from deficit accumulation in multiple body systems, with exaggerated vulnerability to external stressors. A growing consensus on defining frailty sets the stage for consensus on operationalization and widespread implementation in care settings. Frailty measurement is not yet integrated into daily clinical practice in Canada. Here, we will present how this integration might occur. We hope to demonstrate that implementation must appeal to inter-professional practice needs in different settings or circumstances. In some settings, methods for frailty case finding are expected to evolve as deemed to be most appropriate to the front-line users. In this "hands-off" approach, care providers, supported by emerging knowledge translation on frailty operationalization, would be informed by their setting and local practices to establish patterns of ad hoc case finding and component definition of frailty. This more nimble case finding strategy would be opportunistic, and would appeal to expert clinicians and self-directed teams who emphasize an individualized health care experience for their patients. In other settings, we can shape frailty case finding by building care algorithms around existing standardized practices and data repositories, leading to a systematic application of frailty measures and a more coordinated process of component definition and care protocols. Here, recommended instruments and data standards must be endorsed by health networks locally, provincially and nationally. The interRAI suite of assessment instruments has pan-Canadian standards in place and its pervasiveness makes it the most obvious starting point, especially in home care and long-term care. We anticipate the evolution of an integrated model informed by stakeholders and settings, where policy makers focus on system supports for frailty case finding, while front-line clinicians use case finding strategies to pinpoint and act on key frailty components. PMID- 30298169 TI - Social and societal implications of frailty, including impact on Canadian healthcare systems. AB - Frailty has many social and societal implications. Social circumstances are key both as contributors to frail older adults' health outcomes and as practical facilitators or barriers to intervention and supports. Frailty also has important societal implications for health systems and social care policy. In this discussion paper, we use a social ecology framework to consider the social and societal implications and impact of frailty at each level, from the individual, through relationships with family and friend caregivers, institutions, health systems, neighborhoods and communities, to society at large. We conclude by arguing that attention to these issues at a policy level is critical. We identify three target actions: 1) Social dimensions of frailty should be systematically considered when frailty is assessed. 2) Action is needed at the level of policies and programs to improve support for caregivers. 3) Policy review across all portfolios will benefit from a social frailty lens. PMID- 30298170 TI - Ethical and Legal Implications of Frailty Screening. AB - Goals of screening for frailty include (a) promoting healthy aging, (b) addressing frailty with preventive and targeted interventions, (c) better aligning social and medical responses to frailty with the needs of frail older adults and (d) preventing harms to frail older adults from excessive and inappropriate medical interventions that are insensitive to the implications of frailty. However, the medicalization of frailty and outcomes of the screening process also risk harming frail older adults and their autonomy through stereotyping and by legitimizing denial of care. This risk of harm gives rise to ethical and legal questions and considerations that this paper addresses. Frailty screening that is ethically defensible will situate and support healthcare that is consistent with people's needs, circumstances and capacity to benefit from the care provided. We also call for an informed consent process that incorporates supported or shared decision making in order to protect the autonomy of frail older adults. PMID- 30298171 TI - Policy and Economic Considerations for Frailty Screening in the Canadian Healthcare System. AB - Canada faces significant policy and economic challenges related to healthcare for frail older adults. Annual per capita healthcare costs for people over age 65 are five times those for people under 65. Flat economic growth and an aging workforce decrease tax revenue, which funds 70% of health spending. Governments are shifting policy to enhance person-centered care and shifting spending from hospitals to primary and community care. Recognizing that frailty and evidence based frailty screening can contribute directly to reform initiatives, what are the policy and economic considerations, both nationally and internationally, around frailty screening that will benefit patients, families and/or the wider health system? Based on key informant interviews, we present recommendations for approaching policy and economic challenges in frailty through the following healthcare policy instruments: financing, funding, legislation, regulation, technology, interdisciplinary care, person-centered service and health promotion. PMID- 30298172 TI - Improving End-of-Life Care and Advance Care Planning for Frail Older Adults in Canad. AB - We present five Key Concepts that describe priorities for improving end-of-life care for frail older adults in Canada, and recommendations based on each Key Concept. Key Concept #1: Our end-of-life care system is focused on cancer, not frailty. Key Concept #2: We need better strategies to systematically identify frail older adults who would benefit from a palliative approach. Key Concept #3: The majority of palliative and end-of-life care will be, and should be, provided by clinicians who are not palliative care specialists. Key Concept #4: Organizational change and innovative funding models could deliver far better end of-life care to frail individuals for less than we are currently spending. Key Concept #5: Improving the quality and quantity of advance care planning for frail older adults could reduce unwanted intensive care and costs at the end of life, and improve the experience for individuals and family members alike. PMID- 30298173 TI - Nutritional Intervention in Sarcopenia: Report from the International Conference on Frailty and Sarcopenia Research Task Force. AB - Research suggests that poor nutrition is an underlying cause of sarcopenia and frailty, and that dietary interventions may prevent or treat age-related loss of muscle mass and strength. In February 2018, the International Conference on Frailty and Sarcopenia Research Task Force explored the current status of research on nutritional interventions for sarcopenia as well as gaps in knowledge, including whether nutritional supplements must be combined with physical activity, and the role of nutritional intervention in sarcopenic obese individuals. The lack of consistency across trials in terms of target populations, assessments, health-care settings, control groups, and choice of outcomes has made it difficult to draw meaningful conclusions from recent studies. The Task Force recommended large randomized controlled trials in heterogeneous, real-world populations to enable sub-group analysis. The field also needs to reach consensus on what outcomes are most meaningful and what represents clinically meaningful change. PMID- 30298174 TI - Association between High Levels of Parathyroid Hormone and Frailty: The Nepean Osteoporosis and Frailty (NOF) Study. AB - BACKGROUND: Frailty is associated with poor outcomes hence identification of risks factors is pivotal. Since the independent role of parathyroid hormone (PTH) in frailty remains unexplored, we aimed to determine this in a population of older individuals with a history of falling. DESIGN: Cross-sectional study. SETTING: Falls and Fracture Clinic, Nepean Hospital (Penrith, Australia). PARTICIPANTS: 692 subjects (mean age=79, 65% women) assessed between 2009-2015. MEASUREMENTS: Assessment included clinical examination, mood, nutrition, grip strength, gait velocity, bone densitometry and posturography. Chemistry included serum PTH, calcium, vitamin D (25(OH)D3), creatinine and albumin. Normocalcemic subjects were divided into 4 groups: (1) Normal: 25(OH)D3 >50nmol/L and PTH between 1.6-6.8pmol/L; (2) PTH responsive: low 25(OH)D3 (<50nmol/L) and high PTH (>6.8pmol/L); (3) PTH unresponsive: low 25(OH)D3 and normal PTH; (4) Hyper PTH (>6.8pmol/L) with normal 25(OH)D3. Frailty was defined using Fried's criteria. Difference between the groups was assessed using one-way ANOVA and X2 analysis. Multinomial logistic regression evaluated the association between the groups and the number of Fried's criteria adjusted for age, BMI, renal function, 25(OH)D3 levels, and albumin. RESULTS: 22.6% subjects had high PTH levels (>6.8pmol/L). All subjects in the high PTH groups had significantly lower grip strength, gait velocity, limits of stability, and higher BMI. The PTH responsive group had a higher risk of pre-frailty (beta=3.8, 95% CI = 3.42 - 5.22, p? 0.01) and frailty (beta=8.26, 95% CI = 2.8-16.1, p<0.01). The risk of frailty was also higher in the Hyper PTH group (beta=2.3, 95% CI = 1.74-4.32, p<0.01). CONCLUSION: We have reported an independent association of high PTH levels with high number of falls and with the clinical components of physical frailty in community dwelling older persons. Our results suggest a possible role of PTH in frailty that deserves further exploration. PMID- 30298177 TI - Older Adults' Perceptions of the Built Environment and Associations with Frailty: A Feasibility and Acceptability Study. AB - It is essential to evaluate frail older adults understanding and execution of survey tools to improve data quality and accurate representation in research. The study tested the feasibility and acceptability of a survey that assesses various measures of functional status in frail older people. The study evaluated: 1) recruitment rate; 2) time to complete questionnaires and difficulties encountered; and 3) acceptability by participants. Validated tools including: FRAIL Scale, EuroQoL 5D-5L, Charlson's Comorbidities Index, Baecke's Physical Activity Questionnaire, Life-Space Assessment, Katz and Lawton ADL and NEWS Walkability Scale were assessed. Twenty-five older patients (63% recruitment rate) of a post-acute restorative program (residential Transition Care Program) in Adelaide, South Australia were interviewed. Although not statistically different, time to complete the overall questionnaire differed between robust, pre-frail and frail participants. Overall, the survey was considered acceptable and feasible, with consideration with NEWS and Life-Space assessment regarding length, phrasing and layout. PMID- 30298175 TI - The Role of Ultrasound as a Diagnostic Tool for Sarcopenia. AB - Sarcopenia is the progressive loss of skeletal mass and strength, particularly in older adults, with consequent reduction in function and independence. Changing population demographics, have resulted in increased prevalence of sarcopenia and this is associated with a considerable economic burden. Whilst simple, effective, non-intrusive management of this condition exists, no routine diagnosis takes place either in the UK or in many other countries, partly due to an absence of pragmatic clinical diagnostic tools to support the early identification of the syndrome. This position paper aims to provide a short overview proposing the potential case for developing ultrasound as a new and alternative diagnostic tool for identifying sarcopenia. PMID- 30298176 TI - Single Physical Performance Measures Cannot Identify Geriatric Outpatients with Sarcopenia. AB - BACKGROUND: Sarcopenia is highly prevalent in the older population and is associated with several adverse health outcomes. Equipment to measure muscle mass and muscle strength to diagnose sarcopenia is often unavailable in clinical practice due to the related expenses while an easy physical performance measure to identify individuals who could potentially have sarcopenia is lacking. OBJECTIVES: This study aimed to assess the association between physical performance measures and definitions of sarcopenia in a clinically relevant population of geriatric outpatients. DESIGN, SETTING AND PARTICIPANTS: A cross sectional study was conducted, consisting of 140 community-dwelling older adults that were referred to a geriatric outpatient clinic. No exclusion criteria were applied. MEASUREMENTS: Physical performance measures included balance tests (side by-side, semi-tandem and tandem test with eyes open and -closed), four-meter walk test, timed up and go test, chair stand test, handgrip strength and two subjective questions on mobility. Direct segmental multi-frequency bioelectrical impedance analysis was used to measure muscle mass. Five commonly used definitions of sarcopenia were applied. Diagnostic accuracy was determined by sensitivity, specificity and area under the curve. RESULTS: Physical performance measures, i.e. side-by-side test, tandem test, chair stand test and handgrip strength, were associated with at least one definition of sarcopenia. Diagnostic accuracy of these physical performance measures was poor. CONCLUSIONS: Single physical performance measures could not identify older individuals with sarcopenia, according to five different definitions of sarcopenia.

PMID- 30298179 TI - Assessment of Instrumental Activities of Daily Living in Older Adults with Subjective Cognitive Decline Using the Virtual Reality Functional Capacity Assessment Tool (VRFCAT). AB - BACKGROUND: Continuing advances in the understanding of Alzheimer's disease progression have inspired development of disease-modifying therapeutics intended for use in preclinical populations. However, identification of clinically meaningful cognitive and functional outcomes for individuals who are, by definition, asymptomatic remains a significant challenge. Clinical trials for prevention and early intervention require measures with increased sensitivity to subtle deficits in instrumental activities of daily living (IADL) that comprise the first functional declines in prodromal disease. Validation of potential endpoints is required to ensure measure sensitivity and reliability in the populations of interest. OBJECTIVES: The present research validates use of the Virtual Reality Functional Capacity Assessment Tool (VRFCAT) for performance based assessment of IADL functioning in older adults (age 55+) with subjective cognitive decline. DESIGN: Cross-sectional validation study. SETTING: All participants were evaluated on-site at NeuroCog Trials, Durham, NC, USA. PARTICIPANTS: Participants included 245 healthy younger adults ages 20-54 (131 female), 247 healthy older adults ages 55-91 (151 female) and 61 older adults with subjective cognitive decline (SCD) ages 56-97 (45 female). MEASURES: Virtual Reality Functional Capacity Assessment Tool; Brief Assessment of Cognition App; Alzheimer's Disease Cooperative Study Prevention Instrument Project - Mail-In Cognitive Function Screening Instrument; Alzheimer's Disease Cooperative Study Instrumental Activities of Daily Living - Prevention Instrument, University of California, San Diego Performance-Based Skills Assessment - Validation of Intermediate Measures; Montreal Cognitive Assessment; Trail Making Test- Part B. RESULTS: Participants with SCD performed significantly worse than age-matched normative controls on all VRFCAT endpoints, including total completion time, errors and forced progressions (p<=0001 for all, after Bonferonni correction). Consistent with prior findings, both groups performed significantly worse than healthy younger adults (age 20-54). Participants with SCD also performed significantly worse than controls on objective cognitive measures. VRFCAT performance was strongly correlated with cognitive performance. In the SCD group, VRFCAT performance was strongly correlated with cognitive performance across nearly all tests with significant correlation coefficients ranging from 0.3 to 0.7; VRFCAT summary measures all had correlations greater than r=0.5 with MoCA performance and BAC App Verbal Memory (p<0.01 for all). CONCLUSIONS: Findings suggest the VRFCAT provides a sensitive tool for evaluation of IADL functioning in individuals with subjective cognitive decline. Strong correlations with cognition across groups suggest the VRFCAT may be uniquely suited for clinical trials in preclinical AD, as well as longitudinal investigations of the relationship between cognition and function. PMID- 30298181 TI - Geographic Clusters of Alzheimer's Disease Mortality Rates in the USA: 2008-2012. AB - IMPORTANCE: The results identified geographic clusters of high and low Alzheimer's disease (AD)-related mortality across the contiguous United States. These clusters identify specific geographic groupings of counties that allow researchers to narrow the focus to identify some of the biopsychosocial variables contributing to increased or decreased AD mortality. OBJECTIVES: To determine the extent to which geographic clusters exist where AD mortality significantly differs from the national average. Such knowledge could further future research in a more focused study of variables that are contributing to these differences. DESIGN: Age adjusted AD mortality rates were analyzed with a spatial cluster analysis using the disease surveillance software SatScanTM. RESULTS: Three large clusters had elevated age-adjusted AD mortality of at least 60% above the national average. These clusters were in Washington State, Iowa, and North and South Dakota. Below average AD mortality was observed in several areas including New York City, and parts of Arizona, California, Arkansas and Texas. Conclusion and Relevance: This study demonstrates the use of disease surveillance methodology in identifying geographic patterns of unusually high or low AD mortality rates in the USA. Such results provide supporting evidence of appropriate locations to test interventions with the goal to reduce AD mortality. PMID- 30298180 TI - Female Sex and Alzheimer's Risk: The Menopause Connection. AB - Along with advanced age and apolipoprotein E (APOE)-4 genotype, female sex is a major risk factor for developing late-onset Alzheimer's disease (AD). Considering that AD pathology begins decades prior to clinical symptoms, the higher risk in women cannot simply be accounted for by their greater longevity as compared to men. Recent investigation into sex-specific pathophysiological mechanisms behind AD risk has implicated the menopause transition (MT), a midlife neuroendocrine transition state unique to females. Commonly characterized as ending in reproductive senescence, many symptoms of MT are neurological, including disruption of estrogen-regulated systems such as thermoregulation, sleep, and circadian rhythms, as well as depression and impairment in multiple cognitive domains. Preclinical studies have shown that, during MT, the estrogen network uncouples from the brain bioenergetic system. The resulting hypometabolic state could serve as the substrate for neurological dysfunction. Indeed, translational brain imaging studies demonstrate that 40-60 year-old perimenopausal and postmenopausal women exhibit an AD-endophenotype characterized by decreased metabolic activity and increased brain amyloid-beta deposition as compared to premenopausal women and to age-matched men. This review discusses the MT as a window of opportunity for therapeutic interventions to compensate for brain bioenergetic crisis and combat the subsequent increased risk for AD in women. PMID- 30298182 TI - Psychometric Evaluation of the Neuropsychological Test Battery in Individuals with Normal Cognition, Mild Cognitive Impairment, or Mild to Moderate Alzheimer's Disease: Results from a Longitudinal Study. AB - BACKGROUND: The Neuropsychological Test Battery (NTB) is a combination of widely used clinical neuropsychological tests measuring memory and executive function and was designed to overcome some of the limitations of the traditionally used Alzheimer's disease Assessment Scale - Cognitive subscale (ADAS-Cog). A previously reported account indicated high levels of NTB reliability in patients with mild-to-moderate Alzheimer's disease (AD) and mild cognitive impairment (MCI). OBJECTIVES: We examined capacity of the Neuropsychological Test Battery (NTB) and its component subtests to measure cognitive change over time. Correlations with other cognitive and functional assessments were also determined. Design, Settings, Participants: This was a multicentre, prospective, non-interventional, longitudinal cohort study involving patients with mild-to moderate AD (n=196), MCI (n=70), or cognitively normal control participants (NC, n=75). INTERVENTION: The NTB, as well as other Clinical Outcome Assessments including, ADAS-Cog, other cognitive measures, functional/behavioral questionnaires, health outcome questionnaires, and resource utilization tools were administered. RESULTS: Mean change from baseline for the NTB composite score and the six individual NTB subtests showed greater reductions in performance over time in the AD and MCI groups, compared with NC group. The ADAS-Cog was found to be more sensitive to change than the NTB in all three populations. CONCLUSIONS: The NTB showed high correlation with the ADAS-Cog and appears to be a sensitive and reliable assessment tool for measuring cognitive decline in patients with mild-to-moderate AD. However, the ADAS-Cog was found to be more sensitive to change over time in both the AD and MCI populations. PMID- 30298184 TI - Pimavanserin: Potential Treatment For Dementia-Related Psychosis. AB - Psychosis is common across dementia types with a prevalence of 20% to 70%. Currently, no pharmacologic treatment is approved for dementia-related psychosis. Atypical antipsychotics are frequently used to treat these disorders, despite significant safety concerns. Pimavanserin, a selective 5-HT2A inverse agonist/antagonist, was approved in the U.S. for treating hallucinations and delusions associated with Parkinson's disease psychosis (PDP). Patients in the pimavanserin group experienced a significant (p=0.001) improvement in Scale for the Assessment of Positive Symptoms - Parkinson's disease (SAPS-PD) scores vs. placebo. In a subgroup analysis of patients with cognitive impairment (MMSE score >=21 but <=24), the observed improvement on the SAPS-PD with pimavanserin (N=50) was also significant (p=0.002) and larger than in the overall study population without an adverse effect on cognition. In a Phase 2 study with pimavanserin in Alzheimer's disease psychosis, pimavanserin significantly (p=0.045) improved psychosis at Week 6 vs. placebo on the NPI-NH Psychosis Score (PS). In a prespecified subgroup of patients with a baseline NPI-NH PS >=12, a substantively larger treatment effect (p=0.011) was observed vs. participants with NPI-NH PS <12. The results of these studies in cognitively impaired patients with PDP provided the scientific foundation for an ongoing study of pimavanserin for treating patients with dementia-related psychosis associated with the most common neurodegenerative disorders. The study uses a relapse-prevention design with the endpoint of time-to-relapse of psychosis to evaluate the long-term efficacy and safety of pimavanserin as a potential treatment for hallucinations and delusions of dementia-related psychosis.

PMID- 30298183 TI - Clinical Application of APOE in Alzheimer's Prevention: A Precision Medicine Approach. AB - Population-attributable risk models estimate that up to one-third of Alzheimer's disease (AD) cases may be preventable through risk factor modification. The field of AD prevention has largely focused on addressing these factors through universal risk reduction strategies for the general population. However, targeting these strategies in a clinical precision medicine fashion, including the use of genetic risk factors, allows for potentially greater impact on AD risk reduction. Apolipoprotein E (APOE), and specifically the APOE epsilon4 variant, is one of the most well-established genetic influencers on late-onset AD risk. In this review, we evaluate the impact of APOE epsilon4 carrier status on AD prevention interventions, including lifestyle, nutrigenomic, pharmacogenomic, AD comorbidities, and other biological and behavioral considerations. Using a clinical precision medicine strategy that incorporates APOE epsilon4 carrier status may provide a highly targeted and distinct approach to AD prevention with greater potential for success.

PMID- 30298188 TI - Altered brain functional network in children with type 1 Gaucher disease: a longitudinal graph theory-based study. AB - PURPOSE: Previous studies have investigated the brain structural abnormalities in children with type I Gaucher disease (GD). The purpose of our study is to investigate the topological efficiency of the brain functional network in children with type 1 GD. METHODS: Twenty-two children diagnosed with type 1 GD and 22 sex- and age-matched healthy controls (HCs) underwent resting-state functional MRI (rs-fMRI) examination. For longitudinal study, the GD patients underwent rs-fMRI examination again after 4.6 years. Graph theoretical analysis was used to assess the brain network topological properties at the global and regional levels. RESULTS: Compared with the HCs, the children with type 1 GD showed a decreased efficiency in functional segregation with a decreased gamma (normalized clustering coefficient). In addition, the balance between functional segregation and integration was disrupted with decreased small-worldness (sigma). At the regional level, the children with type 1 GD showed significantly decreased nodal degree and efficiency in the right precentral gyrus (PreCG.R) and left postcentral gyrus (PoCG.L). The significantly altered gamma, sigma, and nodal degree in the PreCG.R and PoCG.L were negatively correlated with the disease duration. No significant alterations in the global and regional topological properties were identified in these patients over time. CONCLUSION: Compared with that of the HCs, the efficiency of the brain functional network in the children with type 1 GD was disrupted, and regional involvement was located in motor- and sensory-related regions.

AB - The principle of self-assessment is performed successfully in a wide variety of medical disciplines and is increasingly gaining importance in orthopedic trauma surgery. Through the development and validation of joint-specific self-assessment questionnaires that enable estimation of the range of motion, a large number of patient-based instruments are available for comprehensive follow-up examination. A recently performed proof of concept study showed a high patient acceptance and therefore the development of a prospective, patient-centered fracture register based on the self-assessment functional analysis seems to be promising. The data obtained should reflect not only the reality of fracture treatment but also generate valuable epidemiological data with which evidence-based guidelines can be formed. PMID- 30298190 TI - [Transcription factors in tumor diagnosis]. AB - Transcription factors are a heterogeneous group of DNA-binding proteins that regulate the transcription of distinct genes. Due to their cell-type specificity and cell lineage restriction, numerous transcription factors have been established in recent years as excellent, sensitive, and specific immunohistochemical tumor markers. As compared to other cytoplasmic and membranous differentiation markers, the nuclear immunolocalization of transcription factors is often more stably preserved. Therefore, cell lineage specific transcription factors can be detected even in poorly differentiated metastatic tumors. However, for their reliable diagnostic use, detailed knowledge is required on their expression profiles, which are often more complex than initially assumed.CDX2 is a sensitive marker for colorectal adenocarcinomas but is also expressed in upper abdominal adenocarcinomas, mucinous carcinomas of lung and ovary, and midgut neuroendocrine tumors. A higher degree of specificity for colorectal origin is provided by SATB2. TTF-1 is a valuable marker particularly for pulmonary adenocarcinomas, but may also be focally expressed "aberrantly" in abdominal and gynecological adenocarcinomas. GATA3 is found in breast and urothelial carcinomas but also in squamous cell carcinomas. PAX8 is a highly sensitive marker of all subtypes of gynecological adenocarcinomas, renal cell carcinomas, and thyroid carcinomas. Further transcription factors characterized by molecular biology have meanwhile become diagnostically relevant, the number of which is increasing.Principally, for the diagnostic use of transcription factors as immunohistochemical tumor markers, clinical and radiological data as well as conventional histopathology should always be carefully considered and if necessary they should be applied in the context of a marker panel.

AB - Physical exercise yields beneficial effects on all types of muscle cells, which are essential for the maintenance of cardiovascular homeostasis and good blood circulation. Daily moderate exercise increases systemic antioxidative capacity, which can lead to the prevention of the onset and progression of oxidative stress related diseases. Therefore, exercise is now widely accepted as one of the best therapeutic strategies for the treatment of ischemic (hypoxic) diseases. Canonical transient receptor potential (TRPC) proteins are non-selective cation channels activated by mechanical stress and/or stimulation of phospholipase C coupled surface receptors. TRPC channels, especially diacylglycerol-activated TRPC channels (TRPC3 and TRPC6; TRPC3/6), play a key role in the development of cardiovascular remodeling. We have recently found that physical interaction between TRPC3 and NADPH oxidase (Nox) 2 under hypoxic stress promotes Nox2 dependent reactive oxygen species (ROS) production and mediates rodent cardiac plasticity, and inhibition of the TRPC3-Nox2 protein complex results in enhancement of myocardial compliance and flexibility similar to that observed in exercise-treated hearts. In this review, we describe current understanding of the roles of TRPC channels in striated muscle (patho)physiology and propose that targeting TRPC-based protein complexes could be a new strategy to imitate exercise therapy. PMID- 30298192 TI - Balancing metabolome coverage and reproducibility for untargeted NMR-based metabolic profiling in tissue samples through mixture design methods. AB - Untargeted metabolomics attempts to acquire a comprehensive and reproducible set of small-molecule metabolites in biological systems. However, metabolite extraction method significantly affects the quality of metabolomics data. In the present study, we calculated the number of peaks (NP) and coefficient of variation (CV) to reflect metabolome coverage and reproducibility in untargeted NMR-based metabolic profiling of tissue samples in rats under different methanol/chloroform/water (MCW) extraction conditions. Different MCW extractions expectedly generated diverse characteristics of metabolome. Moreover, the classic MCW method revealed tissue-specific differences in the NP and CV values. To obtain high-quality metabolomics data, therefore, we used mixture design methods to optimize the MCW extraction strategy by maximizing the NP value and minimizing the CV value in each tissue sample. Results show that the optimal formulations of MCW extraction were 2:2:8 (ml/mg tissue) for brain sample, 2:4:6 (ml/mg tissue) for heart sample, 1.3:2:8.7 (ml/mg tissue) for liver sample, 4:2:6 (ml/mg tissue) for kidney sample, 2:3:7 (ml/mg tissue) for muscle sample, and 2:4:6 (ml/mg tissue) for pancreas sample. Therefore, these findings demonstrate that different tissue samples need a specific optimal extraction condition for balancing metabolome coverage and reproducibility in the untargeted metabolomics study. Mixture design method is an effective tool to optimize metabolite extraction strategy for tissue samples. Graphical abstract ?.

AB - A sensitive and disposable amperometric immunosensor for Saccharomyces cerevisiae was constructed by using carbon screen-printed electrodes modified with propionic acid-functionalized graphene oxide as transduction element. The affinity-based biosensing interface was assembled by covalent immobilization of a specific polyclonal antibody on the carboxylate-enriched electrode surface via a water soluble carbodiimide/N-hydroxysuccinimide coupling approach. A concanavalin A peroxidase conjugate was further used as signaling element. The immunosensor allowed the amperometric detection of the yeast in buffer solution and white wine samples in the range of 10-107 CFU/mL. This electroanalytical device also exhibited low detection limit and high selectivity, reproducibility, and storage stability. The immunosensor was successfully validated in spiked white wine samples.

AB - The objective of the present study is to mathematically model the integrated kinetics of drug release in a polymeric matrix and its ensuing drug transport to the encompassing biological tissue. The model embodies drug diffusion, dissolution, solubilization, polymer degradation and dissociation/recrystallization phenomena in the polymeric matrix accompanied by diffusion, advection, reaction, internalization and specific/nonspecific binding in the biological tissue. The model is formulated through a system of nonlinear partial differential equations which are solved numerically in association with pertinent set of initial, interface and boundary conditions using suitable finite difference scheme. After spatial discretization, the system of nonlinear partial differential equations is reduced to a system of nonlinear ordinary differential equations which is subsequently solved by the fourth-order Runge-Kutta method. The model simulations deal with the comparison between a drug delivery from a biodegradable polymeric matrix and that from a biodurable polymeric matrix. Furthermore, simulated results are compared with corresponding existing experimental data to manifest the efficaciousness of the advocated model. A quantitative analysis is performed through numerical computation relied on model parameter values. The numerical results obtained reveal an estimate of the effects of biodegradable and biodurable polymeric matrices on drug release rates. Furthermore, through graphical representations, the sensitized impact of the model parameters on the drug kinetics is illustrated so as to assess the model parameters of significance. PMID- 30298195 TI - The clinical features and outcome of scan-negative and scan-positive cases in suspected cauda equina syndrome: a retrospective study of 276 patients. AB - BACKGROUND: The majority of patients presenting with suspected clinical cauda equina syndrome (CES) have no identifiable structural cause for their symptoms ('scan-negative' CES). Understanding these patients aids clinical differentiation and management in CES. METHODS: A retrospective electronic note review was undertaken of patients presenting with suspected CES, defined as >= 1 of acute bladder, bowel, sexual dysfunction or saddle numbness, to a regional neurosciences centre. We investigated radiology, clinical features, psychiatric and functional disorder comorbidities and outcome of patients with 'scan negative' CES and patients with MRI confirmed compression of the cauda equina ('scan-positive' CES). RESULTS: 276 patients were seen over 16 months. There were three main radiologically defined patient groups: (1) 'scan-positive' CES (n = 78, mean age 48 years, 56% female), (2) 'scan-negative' CES without central canal stenosis but with lumbosacral nerve root compression not explaining the clinical presentation (n = 87, mean age 43 years, 68% female) and (3) 'scan-negative' CES without neural compromise (n = 104, mean age 42 years, 70% female). In the two 'scan-negative' groups (no neural compromise and nerve root compression), there were higher rates of functional disorders (37% and 29% vs. 9%), functional neurological disorders (12% and 11% vs 0%) and psychiatric comorbidity (53% and 40% vs 20%). On follow-up (mean 13-16 months), only 1 of the 191 patients with 'scan-negative' CES was diagnosed with an explanatory neurological disorder (transverse myelitis). CONCLUSIONS: The data support a model in which scan negative cauda equina syndrome arises as an end pathway of acute pain, sometimes with partly structural findings and vulnerability to functional disorders. PMID- 30298198 TI - Stochastic Dynamics of the Latently Infected Cell Reservoir During HIV Infection. AB - The presence of cells latently infected with HIV is currently considered to be a major barrier to viral eradication within a patient. Here, we consider birth death-immigration models for the latent cell population in a single patient, and present analytical results for the size of this population in the absence of treatment. We provide results both at steady state (viral set point), and during the non-equilibrium setting of early infection. We obtain semi-analytic results showing how latency-reversing drugs might be expected to affect the size of the latent pool over time. We also analyze the probability of rare mutant viral strains joining the latent cell population, allowing for steady-state and dynamic viral populations within the host. PMID- 30298199 TI - Ureteral stents for malignant extrinsic ureteral obstruction: outcomes and factors predicting stent failure. AB - BACKGROUND: This study investigated the clinical outcomes of stent placement for malignant extrinsic ureteral obstruction (MUO) and predictive factors for stent failure. METHODS: We retrospectively analyzed clinical data for 91 patients with radiologically significant hydronephrosis due to MUO who underwent successful stent placement. In total, 132 ureters were stented for the decompression. Factors related to stent failure were analyzed with a Cox proportional hazards model. RESULTS: Stent failure occurred in 25 ureters in 20 patients. The median interval to failure was 63 days. The multivariate analysis showed that the significant predictors of stent failure were bladder invasion and severe hydronephrosis before the stent insertion. The patients were divided into three groups based on these two factors: low-risk (neither factor; 85 patients), intermediate-risk (one factor; 37), and high-risk (both factors; 10). The median stent failure-free survival rate at 3 months was 94.8% in the low-risk, 71.8% in the intermediate-risk and 55.6% in the high-risk group, respectively. Of the ureters with stent failure, there was successful re-replacement of internal stents in 3 low-risk, 6 intermediate-risk and no high-risk ureters. Replacement by nephrostomy was done in 2 low-risk, 5 intermediate-risk and 7 high-risk ureters. CONCLUSION: The patients considered at low-risk could be managed without stent failure by internal stenting. However, the patients at high-risk may require the consideration of nephrostomy or other alternatives as the initial treatment. Our stratification model may allow better risk stratification for patients with regard to ureteral stenting, helping to identify patients for whom ureteral stenting is indicated. PMID- 30298200 TI - Transmission of cotton leaf curl disease: answer to a long-standing question. AB - Cotton leaf curl disease (CLCuD) has been a major constraint to cotton production across Pakistan and northwestern India since the early 1990s. The disease is caused by a number of begomoviruses, including Cotton leaf curl Multan virus (CLCuMuV), which associate with a specific host range and symptom determining betasatellite known as Cotton leaf curl Multan betasatellite (CLCuMuB). Bemisia tabaci is a complex of cryptic species that consists of numerous (> 44) morphologically indistinguishable and, at least partially, reproductively isolated species. CLCuD has recently been introduced into parts of China but has not, at least so far, become a problem in the major cotton regions. The disease in China has been shown to be caused by CLCuMuV with CLCuMuB, which is believed to have been introduced from South Asia in ornamental plants. To understand the basis for this lack of spread of CLCuD into the cotton-growing areas of China, Pan et al. (Phytopathology 108:1172-1183, 2018) investigated the transmission of CLCuMuV/CLCuMuB by B. tabaci. The study showed that, of the four cryptic B. tabaci species investigated, only the cryptic species Asia II 1 was able to efficiently transmit CLCuMuV/CLCuMuB. Significantly, Asia II 1 is not present in the major cotton-growing regions of China. The results of Pan et al. (Phytopathology 108:1172-1183, 2018) are discussed with particular emphasis on the situation of CLCuD in Pakistan and northwestern India, which differs significantly from the situation in China. PMID- 30298202 TI - Similar neurocognitive outcomes after 48 weeks in HIV-1-infected participants randomized to continue tenofovir/emtricitabine + atazanavir/ritonavir or simplify to abacavir/lamivudine + atazanavir. AB - Human immunodeficiency virus (HIV)-associated neurocognitive disorders can persist in many patients despite achieving viral suppression while on antiretroviral therapy (ART). Neurocognitive function over 48 weeks was evaluated using a Cogstate test battery assessing psychomotor function, attention, learning, and working memory in 293 HIV-1-infected, ART-experienced, and virologically suppressed adults. The ASSURE study randomized participants 1:2 to remain on tenofovir/emtricitabine (TDF/FTC) and ritonavir-boosted atazanavir (ATV/r) or simplify to abacavir/lamivudine + atazanavir (ABC/3TC + ATV). Neurocognitive z-scores were computed using demographically adjusted normative data and were classified as "impaired" (defined as either a z-score <= - 2 or having 2 or more standardized individual test z-scores <= - 1); while higher scores (equaling better performance) were classified as "normal". By z-scores, 54.7% of participants had impaired neurocognition at baseline and 50.2% at week 48. There were no significant differences (p < 0.05) in the baseline-adjusted performance between treatment groups for any individual test or by z-score. Specific demographic and medical risk factors were evaluated by univariate analysis for impact on neurocognitive performance. Factors with p < 0.10 were evaluated by backwards regression analysis to identify neurocognition-correlated factors after accounting for treatment, assessment, and baseline. Four risk factors at baseline for impaired neurocognition were initially identified: lower CD4 nadir lymphocyte counts, higher Framingham risk scores, and interleukin-6 levels, and a history of psychiatric disorder not otherwise specified, however none were found to moderate the effect of treatment on neurocognition. In this aviremic, treatment-experienced population, baseline-adjusted neurocognitive function remained stable and equivalent over 48 weeks with both TDF/FTC + ATV/r treated and in the ART-simplified ABC/3TC + ATV treatment groups. PMID- 30298203 TI - Effects of age, HIV, and HIV-associated clinical factors on neuropsychological functioning and brain regional volume in HIV+ patients on effective treatment. AB - It is yet unclear if people infected with human immunodeficiency virus (HIV+) on stable, combined antiretroviral therapies (cARTs) decline with age at the same or greater rate than healthy people. In this study, we examined independent and interactive effects of HIV, age, and HIV-related clinical parameters on neuropsychological functioning and brain regional volume in a sizable group of Polish HIV+ men receiving cART. We also estimated the impact of nadir CD4 cell count, CD4 cell count during participation in the study, duration of HIV infection, or duration of cART along with age. Ninety-one HIV+ and 95 control (HIV-) volunteers ages 23-75 completed a battery of neuropsychological tests, and 54 HIV+ and 62 HIV- of these volunteers participated in a brain imaging assessment. Regional brain volume in the cortical and subcortical regions was measured using voxel-based morphometry. We have found that HIV and older age were independently related to lower attention, working memory, nonverbal fluency, and visuomotor dexterity. Older age but not HIV was associated with less volume in several cortical and subcortical brain regions. In the oldest HIV+ participants, age had a moderating effect on the relationship between the duration of cART and visuomotor performance, such as that older age decreased speed of visuomotor performance along with every year on cART. Such results may reflect the efficacy of cART in preventing HIV-associated brain damage. They also highlight the importance of monitoring neuropsychological functioning and brain structure in HIV+ patients. This is particularly important in older patients with long adherence to cART.

PMID- 30298201 TI - Functional MRI and delay discounting in patients infected with hepatitis C. AB - Hepatitis C virus-infected (HCV+) adults evidence increased rates of psychiatric and cognitive difficulties. This is the first study to use functional magnetic resonance imaging (fMRI) to examine brain activation in untreated HCV+ adults. To determine whether, relative to non-infected controls (CTLs), HCV+ adults exhibit differences in brain activation during a delay discounting task (DDT), a measure of one's tendency to choose smaller immediate rewards over larger delayed rewards one aspect of impulsivity. Twenty adults with HCV and 26 CTLs completed an fMRI protocol during the DDT. Mixed effects regression analyses of hard versus easy trials of the DDT showed that, compared with CTLs, the HCV+ group exhibited less activation in the left lateral occipital gyrus, precuneus, and superior frontal gyrus. There were also significant interactive effects for hard-easy contrasts in the bilateral medial frontal gyrus, left insula, left precuneus, left inferior parietal lobule, and right temporal occipital gyrus; the CTL group evidenced a positive relationship between impulsivity and activation, while the HCV+ group exhibited a negative relationship. Within the HCV+ group, those with high viral load chose immediate rewards more often than those with low viral load, regardless of choice difficulty; those with low viral load chose immediate rewards more often on hard choices relative to easy choices. Results show that HCV+ patients exhibit greater impulsive behavior when presented with difficult choices, and impulsivity is negatively related to activation in regions important for cognitive control. Thus, interventions that decrease impulsive choice may be warranted with some HCV+ patients. PMID- 30298205 TI - Rouhier's colpocleisis with concomitant vaginal hysterectomy: an instructive video for female pelvic surgeons. AB - INTRODUCTION AND HYPOTHESIS: The treatment of pelvic organ prolapse (POP) in elderly women can be challenging. The vaginal operation known as colpocleisis, the total occlusion of the urogenital hiatus, with concomitant hysterectomy was described by Rouhier and represents a safe, time-saving, and reproducible procedure in the case of POP associated with uterine pathological conditions. It is suitable for elderly women who do not require preservation of coital function. The objective of this video is to provide anatomical illustrations and a precise description of the surgical steps. METHODS: We present the case of a 62-year-old woman who was referred for hysterectomy in the context of metastatic endometrial cancer. She complained about vaginal bulge and was diagnosed with a POP-Q stage 4 genital prolapse on physical examination. Due to important comorbidities such as arterial hypertension, obesity, and three-site metastatic disease, we suggested a colpocleisis with concomitant vaginal hysterectomy. This approach was intended to treat the prolapse and perform a palliative surgery to alleviate abnormal uterine bleeding. RESULTS: This video illustrates the different surgical steps of a colpohysterectomy according to Rouhier. No intraoperative complications occurred and the postoperative follow-up was uneventful. The patient was fully satisfied and POP has not recurred after a 17-month follow-up. CONCLUSIONS: Colpocleisis should remain an exceptional approach, but could be offered to sexually inactive women of advanced age after thorough discussion and patient consent. If a hysterectomy is necessary, Rouhier's operation offers a time-saving, reproducible, and efficient option for women with symptomatic POP who do not desire future vaginal intercourse.

AB - INTRODUCTION AND HYPOTHESIS: The present video shows a rare case of erosion through the full rectal wall into the rectum after a transperineal implant of a double-arm polypropylene kit. METHODS: A 70-year-old woman underwent a transperineal implant of a double-arm polypropylene kit. One year after surgery, she developed bothersome symptoms in the posterior perineum including heaviness, pain and rectal bleeding during defecation. A clinical examination showed the presence of a part of the prothesis traversing the rectal cavity. A minimally invasive transanal approach was performed to remove the mesh and restore the rectal integrity. RESULTS: This surgical technique demonstrates rectal mesh removal with a transanal approach. CONCLUSIONS: To our knowledge, this is a rare complication of rectal erosion of a posterior transperineal mesh kit. The aim of this video is to show a complete transanal approach to treating this serious complication avoiding the more invasive and traumatic abdominal procedure. PMID- 30298207 TI - Choline and choline-related nutrients in regular and preterm infant growth. AB - BACKGROUND: Choline is an essential nutrient, with increased requirements during development. It forms the headgroup of phosphatidylcholine and sphingomyelin in all membranes and many secretions. Phosphatidylcholine is linked to cell signaling as a phosphocholine donor to synthesize sphingomyelin from ceramide, a trigger of apoptosis, and is the major carrier of arachidonic and docosahexaenoic acid in plasma. Acetylcholine is important for neurodevelopment and the placental storage form for fetal choline supply. Betaine, a choline metabolite, functions as osmolyte and methyl donor. Their concentrations are all tightly regulated in tissues. CLINCAL IMPACT: During the fetal growth spurt at 24-34-week postmenstrual age, plasma choline is higher than beyond 34 weeks, and threefold higher than in pregnant women [45 (36-60) umol/L vs. 14 (10-17) umol/L]. The rapid decrease in plasma choline after premature birth suggests an untimely reduction in choline supply, as cellular uptake is proportional to plasma concentration. Supply via breast milk, with phosphocholine and alpha glycerophosphocholine as its major choline components, does not prevent such postnatal decrease. Moreover, high amounts of liver PC are secreted via bile, causing rapid hepatic choline turnover via the enterohepatic cycle, and deficiency in case of pancreatic phospholipase A2 deficiency or intestinal resection. Choline deficiency causes hepatic damage and choline accretion at the expense of the lungs and other tissues. CONCLUSION: Choline deficiency may contribute to the impaired lean body mass growth and pulmonary and neurocognitive development of preterm infants despite adequate macronutrient supply and weight gain. In this context, a reconsideration of current recommendations for choline supply to preterm infants is required. PMID- 30298208 TI - The Yin-Yang of CYP3A4: a Bayesian meta-analysis to quantify inhibition and induction of CYP3A4 metabolism in humans and refine uncertainty factors for mixture risk assessment. AB - Quantifying differences in pharmacokinetics (PK) and toxicokinetics (TK) provides a science-based approach to refine uncertainty factors (UFs) for chemical risk assessment. Cytochrome P450 (CYP) 3A4-the major hepatic and intestinal human CYP and the P-glycoprotein (Pgp) transporter share a vast range of common substrates for which PK may be modulated through inhibition or induction in the presence of grapefruit juice (GFJ) or St. John's wort (SJW), respectively. Here, an extensive literature search was performed on PK interactions for CYP3A4 and Pgp substrates after oral co-exposure to GFJ and SJW. Relevant data from 109 publications, extracted for both markers of acute (Cmax) and chronic [clearance and area under the plasma concentration-time curve (AUC)] exposure, were computed into a Bayesian hierarchical meta-analysis model. Bioavailability (F) and substrate fraction metabolised by CYP3A4 (Fm) were identified as the variables exhibiting the highest impact on the magnitude of interaction. The Bayesian meta-regression model developed provided good predictions for magnitudes of inhibition (maximum 5.3-fold with GFJ) and induction (maximum 2.3-fold with SJW). Integration of CYP3A4 variability, F, Fm and magnitude of interaction provided the basis to derive a range of CYP3A4 and Pgp-related UFs. Such CYP3A4 and Pgp-related UFs can be derived in the absence of human data using in vitro TK evidence for CYP3A4/Pgp inhibition or induction as conservative in silico options. The future development of quantitative in vitro-in vivo extrapolation models for mixture risk assessment is discussed with particular attention to integrating human in vitro and in vivo P/TK data on interactions with pathway-related variability. PMID- 30298209 TI - Major changes of cell function and toxicant sensitivity in cultured cells undergoing mild, quasi-natural genetic drift. AB - Genomic drift affects the functional properties of cell lines, and the reproducibility of data from in vitro studies. While chromosomal aberrations and mutations in single pivotal genes are well explored, little is known about effects of minor, possibly pleiotropic, genome changes. We addressed this question for the human dopaminergic neuronal precursor cell line LUHMES by comparing two subpopulations (SP) maintained either at the American-Type-Culture Collection (ATCC) or by the original provider (UKN). Drastic differences in susceptibility towards the specific dopaminergic toxicant 1-methyl-4 phenylpyridinium (MPP+) were observed. Whole-genome sequencing was performed to identify underlying genetic differences. While both SP had normal chromosome structures, they displayed about 70 differences on the level of amino acid changing events. Some of these differences were confirmed biochemically, but none offered a direct explanation for the altered toxicant sensitivity pattern. As second approach, markers known to be relevant for the intended use of the cells were specifically tested. The "ATCC" cells rapidly down-regulated the dopamine transporter and tyrosine-hydroxylase after differentiation, while "UKN" cells maintained functional levels. As the respective genes were not altered themselves, we conclude that polygenic complex upstream changes can have drastic effects on biochemical features and toxicological responses of relatively similar SP of cells. PMID- 30298210 TI - Does 3-T fetal MRI induce adverse acoustic effects in the neonate? A preliminary study comparing postnatal auditory test performance of fetuses scanned at 1.5 and 3 T. AB - BACKGROUND: Fetal MRI at 3 T is associated with increased acoustic noise relative to 1.5 T. OBJECTIVE: The goal of this study is to determine if there is an increased prevalence of congenital hearing loss in neonates who had a 3-T prenatal MR vs. those who had it at 1.5 T. MATERIALS AND METHODS: We retrospectively identified all subjects who had 3-T fetal MRI between 2012 and 2016 and also underwent universal neonatal hearing screening within 60 days of birth. Fetuses with incomplete hearing screening, magnetic resonance imaging (MRI) studies at both field strengths or fetuses affected by conditions associated with hearing loss were excluded. A random group of controls scanned at 1.5 T was identified. Five subjects had repeat same-strength MRIs (one at 3 T and four at 1.5 T). The pass/fail rate of the transient otoacoustic emissions test and auditory brainstem response test were compared using the Fisher exact test. A logistic regression was performed to assess the effects of other known risk factors for congenital hearing loss. RESULTS: Three hundred forty fetal MRI examinations were performed at 3 T, of which 62 met inclusion criteria. A control population of 1.5-T fetal MRI patients was created using the same exclusion criteria, with 62 patients randomly selected from the eligible population. The fail rates of transient otoacoustic emissions test for the 1.5-T and 3-T groups were 9.7% and 6.5%, respectively, and for the auditory brainstem response test were 3.2% and 1.6%, respectively. There was no significant difference in the fail rate of either test between groups (P=0.74 for transient otoacoustic emissions test, and P=0.8 for auditory brainstem response test). The median gestational age of the 3-T group was 30 weeks, 1 day, significantly higher (P<0.001) than the 1.5 T group (median gestational age: 20 weeks, 2 days). CONCLUSION: Our findings suggest that the increase in noise associated with 3 T does not increase the rate of clinically detectable hearing abnormalities. PMID- 30298211 TI - Pilot study on renal magnetic resonance diffusion tensor imaging: are quantitative diffusion tensor imaging values useful in the evaluation of children with ureteropelvic junction obstruction? AB - BACKGROUND: Ureteropelvic junction (UPJ) obstruction is a common cause of renal injury in children. Indications for surgery are still controversial. Currently, there is no threshold to differentiate patients with suspected UPJ obstruction requiring surgery from the ones that do not, or to predict renal outcome after surgery. Several studies have demonstrated that diffusion tensor imaging (DTI) results may correlate with microstructural changes in the kidneys. OBJECTIVE: To evaluate the feasibility of using DTI to identify UPJ obstruction kidneys. MATERIALS AND METHODS: We analyzed functional MR urography (fMRU) with renal DTI (b=0 and b=400, 20 directions, 1.5 Tesla, no respiratory triggering) in 26 kidneys of 19 children (mean age: 6.15 years) by comparing 13 kidneys with UPJ obstruction configuration that underwent pyeloplasty following the fMRU, and 13 anatomically normal age- and gender-matched kidneys. DTI tractography was reconstructed using a fractional anisotropy threshold of 0.10 and an angle threshold of 55 degrees . User-defined regions of interest (ROIs) of the renal parenchyma (excluding collecting system) were drawn to quantify DTI parameters: fractional anisotropy, apparent diffusion coefficient (ADC), track length and track volume. The failure rate was evaluated. RESULTS: All DTI parameters changed with age; fractional anisotropy decreased (P<0.032). Track volume and track length increased (P<0.05). ADC increased with age in normal kidneys (P<0.001) but not in UPJ obstruction kidneys (P=0.11). After controlling for age, the fractional anisotropy (UPJ obstruction mean: 0.18, normal kidney mean: 0.21; P=0.001) and track length (UPJ obstruction mean: 11.9 mm, normal kidney mean: 15.4 mm; P<0.001) were lower in UPJ obstruction vs. normal kidneys. There was a trend toward a higher ADC in UPJ obstruction kidneys vs. normal kidneys (P=0.062). The failure rate in UPJ obstruction kidneys due to technical limitations of DTI was 13/26 (50%). CONCLUSION: We demonstrated that fractional anisotropy is lower in UPJ obstruction than in normal kidneys. It is necessary to improve this technique to increase the success rate and to perform more studies to evaluate if a decrease in fractional anisotropy can differentiate UPJ obstruction kidneys from hydronephrotic kidneys without UPJ obstruction. PMID- 30298212 TI - An Automated Grading and Diagnosis System for Evaluation of Dry Eye Syndrome. AB - This article describes methods used to determine the severity of Dry Eye Syndrome (DES) based on Oxford Grading Schema (OGS) automatically by developing and applying a decider model. The number of dry punctate dots occurred on corneal surface after corneal fluorescein staining can be used as a diagnostic indicator of DES severity according to OGS; however, grading of DES severity exactly by carefully assessing these dots is a rather difficult task for humans. Taking into account that current methods are also subjectively dependent on the perception of the ophtalmologists coupled with the time and resource intensive requirements, enhanced diagnosis techniques would greatly contribute to clinical assessment of DES. Automated grading system proposed in this study utilizes image processing methods in order to provide more objective and reliable diagnostic results for DES. A total of 70 fluorescein-stained cornea images from 20 patients with mild, moderate, or severe DES (labeled by an ophthalmologist in the Keratoconus Center of Yildirim Beyazit University Ataturk Training and Research Hospital) used as the participants for the study. Correlations between the number of dry punctate dots and DES severity levels were determined. When automatically created scores and clinical scores were compared, the following measures were observed: Pearson's correlation value between the two was 0.981; Lin's Concordance Correlation Coefficients (CCC) was 0.980; and 95% confidence interval limites were 0.963 and 0.989. The automated DES grade was estimated from the regression fit and accordingly the unknown grade is calculated with the following formula: Gpred = 1.3244 log(Ndots) - 0.0612. The study has shown the viability and the utility of a highly successful automated DES diagnostic system based on OGS, which can be developed by working on the fluorescein-stained cornea images. Proper implemention of a computationally savvy and highly accurate classification system, can assist investigators to perform more objective and faster DES diagnoses in real-world scenerios.

AB - Development of leaf rust-resistant cultivars is a priority during wheat breeding, since leaf rust causes major losses in yield. Resistance against leaf rust due to Lr genes is partly controlled by epigenetic modifications including histone acetylation that is known to respond to biotic/abiotic stresses. In the present study, enrichment of H3K4ac and H3K9ac in promoters of six defense responsive genes (N-acetyltransferase, WRKY 40, WRKY 70, ASR1, Peroxidase 12 and Sarcosine oxidase) was compared with their expression in a pair of near-isogenic lines (NILs) for the gene Lr28 following inoculation with leaf rust pathotype '77-5'; ChIP-qPCR was used for this purpose. The proximal and distal promoters of these genes contained a number of motifs that are known to respond to biotic stresses. The enrichment of two acetylation marks changed with passage of time; changes in expression of two of the six genes (N-acetyltransferase and peroxidase12), largely matched with changes in H3K4/H3K9 acetylation patterns of the two promoter regions. For example, enrichment of both the marks matched with higher expression of N-acetyltransferase gene in susceptible NIL and the deacetylation (H3K4ac) largely matched with reduced gene expression in resistant NIL. In peroxidase12, enrichment of H3K4ac and H3K9ac largely matched with higher expression in both the NILs. In the remaining four genes, changes in H3 acetylation did not always match with gene expression levels. This indicated complexity in the regulation of the expression of these remaining four genes, which may be controlled by other epigenetic/genetic regulatory mechanisms that need further analysis.

AB - PURPOSE: We aimed to compare the histomorphological features of oral lymphoepithelial cysts (OLC) in different locations of the oral cavity and to verify the association between oral lymphoepithelial cysts and subgemmal neurogenous plaque (SNP) on biopsies from the lateral border of the tongue. METHODS: All cases diagnosed as OLC from the Oral Pathology Service at the School of Dentistry/University of Sao Paulo were retrieved. For all the cysts located in the tongue, their association to SNP was analyzed. Immunohistochemical staining against S100 was performed to confirm the diagnosis of SNP. RESULTS: Thirty-one cases were selected for morphological analysis and SNP was identified in 40% of cases, all of them positive for S100. In these cases, macroscopic analysis demonstrated two independent fragments. Microscopic analysis showed that cysts located in the floor of the mouth and ventral surface of the tongue showed less intense exocytosis, less formation of lymphoid follicles, and predominantly a moderate inflammatory infiltrate. CONCLUSIONS: OLC have a similar histological pattern regardless the location within the oral cavity and. In some cases, the biopsy specimen may be accompanied by a SNP as an adjacent independent structure. PMID- 30298215 TI - More women gynecologists in Belgium: assessment of changes in the workforce-a survey. AB - CONTEXT AND OBJECTIVE: International data highlight the increasing participation of women in the workforce in the medical field and particularly among obstetricians and gynecologists (OB-GYN). Some studies reported a gender difference in work productivity and practice patterns. The aim of this study is to analyze whether disparities exist between male and female OB-GYN in their practices with potential consequences for the organization of the OB-GYN departments. METHODS: A survey of all active, Belgian OB-GYNs concerning their professional activity and well-being and a survey of the heads of OG departments evaluating the impact of feminisation on their department. RESULTS: The response rate was 43% (n = 615). Women and men worked a similar number of half-days per week, respectively, 10.1 +/- 2.4 and 10.3 +/- 3.2 (p = 0.26) but women treated less patients per week (80 versus 90, p = 0.034). Pear year, women and men perform, respectively, 108 and 184 surgical procedures (p = 0.0001) plus 114 and 100 deliveries (p = 0.09). Female OB-GYNs have fewer children but the size of their family has no bearing on work hours. Qualitatively, most OB-GYN regardless of their gender, consider their profession to be gratifying. Dissatisfaction is related to organizational concerns for women and to pressure of competitiveness for men. Women are more concerned about their private life and men more focussed on their professional career. However, both expressed the primary importance of good health and quality of life. A majority (66%) of head of departments do not consider that the feminisation of their staff is problematic. CONCLUSION: There was no difference in time spent at work between male and female OB-GYN. The number of patients treated by female OB-GYN per week is smaller which means that the time spent per patient is higher. The OG profession does not appear to be jeopardized by its feminisation according to this study and the opinion of the head of departments. Nevertheless, we need to take into account when organizing the future workforce that women tend to focus more on the time spent with patients than on surgical procedures.

PMID- 30298217 TI - [Diagnoses of thyroid disorders in ENT and general practices in Germany between 2008 and 2016]. AB - OBJECTIVE: The aim of this study was to investigate thyroid disorder diagnoses in otorhinolaryngologic (ENT) practices in Germany compared to general (GP) practices using data from a representative Germany-wide practice database. METHODS: The database was retrospectively searched for diagnoses of thyroid disorders made in ENT and GP practices between January 2008 and December 2016. Data were collected on the most common three-character disease classes (categories) from the "Disorders of thyroid gland" (E00-E07) group as well as the "Benign neoplasm of thyroid gland" (D34) and "Malignant neoplasm of thyroid gland" (C73) categories. The periods 2008-2010, 2011-2013, and 2014-2016 were evaluated. RESULTS: The database included 71 ENT and 506 GP practices with continuous participation from 2008 to 2016. The relative frequency (patients/practice) of diagnoses from the "Disorders of thyroid gland" group was 4.4-times higher in GP than in ENT practices. The relative frequency of benign neoplasms of the thyroid gland was 5-times higher in GP than in ENT practices. The relative frequency of malignant neoplasms of the thyroid gland was almost identical in GP and ENT practices. The most frequent diagnoses in both ENT and GP practices were found in the categories "Other nontoxic goiter" (E04) and "Other hypothyroidism" (E03). Diagnoses in the categories "Hyperthyroidism" (E05) and "Thyroiditis" (E06) were less frequent. Diagnoses of thyroid neoplasms were the least frequent, with benign neoplasms diagnosed more frequently in GP practices and malignant neoplasms diagnosed more frequently in ENT practices. During the study period, the diagnostic frequency of thyroid diseases decreased in ENT practices, whereas it increased in GP practices. CONCLUSION: Despite the increasing interest in establishing thyroid surgery in ENT clinics in Germany in recent years, thyroid diagnoses in ENT practices in Germany have been continuously declining, whereas they have considerably increased in GP practices. The reason for this may be health insurance provider-related differences in reimbursement practices for GPs and specialists. PMID- 30298219 TI - Herpes zoster infection and statins: which implications in clinical practice? AB - Herpes zoster (HZ), which is caused by reactivation of latent varicella zoster virus (VZV), constitutes a major public health concern in both short- and long term periods. Over the last years, several epidemiological studies have demonstrated that statin use is associated with increased risk of HZ at cerebral level. Because statins are among the most popular and best-selling drugs in western countries, this potential negative pleiotropic effect could have important implications in the daily clinical practice. In the present manuscript, we reviewed the available data on the statin use and the relative risk of HZ infection. PMID- 30298218 TI - Stem Cell Therapy in Cerebrovascular Disease. AB - PURPOSE OF REVIEW: The purpose of this article is to provide a review of state-of the-art cellular therapy in cerebrovascular diseases by discussing published and ongoing clinical trials. RECENT FINDINGS: In spite of the challenge in translating the success of cellular therapy in acute strokes from preclinical models to clinical trials, early phase clinical trial have recently shown promise in overcoming these challenges. Various stem cell types and doses are being studied, different routes of administration are under investigation, as well as defining the optimal time window to intervene. In addition, experimental methods to enhance cellular therapy, such as ischemic preconditioning, are evolving. After the failure of neuroprotectants in cerebrovascular diseases, researchers have been keen to provide a way of replacement of damaged brain tissue and to promote recovery in order to achieve better outcomes. The field has progressed from intravenous delivery in the 24- to 36-h time window to later intracerebral administration in chronic stroke in clinical trials. New optimism in acute stroke care fostered by the success of mechanical thrombectomy will hopefully extend into cell therapy to promote recovery.

PMID- 30298220 TI - A common goodness-of-fit framework for neural population models using marked point process time-rescaling. AB - A critical component of any statistical modeling procedure is the ability to assess the goodness-of-fit between a model and observed data. For spike train models of individual neurons, many goodness-of-fit measures rely on the time rescaling theorem and assess model quality using rescaled spike times. Recently, there has been increasing interest in statistical models that describe the simultaneous spiking activity of neuron populations, either in a single brain region or across brain regions. Classically, such models have used spike sorted data to describe relationships between the identified neurons, but more recently clusterless modeling methods have been used to describe population activity using a single model. Here we develop a generalization of the time-rescaling theorem that enables comprehensive goodness-of-fit analysis for either of these classes of population models. We use the theory of marked point processes to model population spiking activity, and show that under the correct model, each spike can be rescaled individually to generate a uniformly distributed set of events in time and the space of spike marks. After rescaling, multiple well-established goodness-of-fit procedures and statistical tests are available. We demonstrate the application of these methods both to simulated data and real population spiking in rat hippocampus. We have made the MATLAB and Python code used for the analyses in this paper publicly available through our Github repository at https://github.com/Eden-Kramer-Lab/popTRT . PMID- 30298222 TI - Factor Structure and Criterion Validity of the Five Cs Model of Positive Youth Development in a Multi-University Sample of College Students. AB - There is growing recognition that clinical and developmental outcomes will be optimized by interventions that harness strengths in addition to ameliorating deficits. Although empirically-supported methods for identifying strengths are available for children and adolescents, this framework has yet to be applied to emerging adulthood. This study evaluates the nature of the Five Cs model of Positive Youth Development (PYD) - character, confidence, competence, connection, and caring - in a sample of emerging adults from six universities (N = 4654; 70% female; 81% White). Historically, PYD has been modeled as either separate correlated factors or a second-order factor structure. More recently, the bifactor model has been recommended to determine the degree to which PYD is unidimensional versus multidimensional. The present study examined the multidimensionality of PYD by comparing the model fit of a one-factor, five correlated factor model, and second-order factor structure with a bifactor model and found support for the bifactor model with evidence of invariance across sex. Criterion validity was also assessed using three criterion measures particularly relevant for adjustment during emerging adulthood: anxiety, depressive symptoms, and emotion regulation difficulties. PYD and the residual Cs tended to correlate negatively with indicators of maladaptive development. Future directions including applications of the PYD framework as a measure of thriving across emerging adulthood are discussed. PMID- 30298223 TI - It Gets Better: Attenuated Associations Between Latent Classes of Peer Victimization and Longitudinal Psychosocial Outcomes in Four Low-Resource Countries. AB - Very few studies of peer victimization have been conducted in low-resource countries, where cultural and contextual differences are likely to influence the dynamics of these experiences in ways that may reduce the generalizability of findings of the larger body of literature. Most studies in these settings are also subject to multiple design limitations that restrict our ability to understand the dynamics of peer victimization experiences. Person-centered approaches such as latent class analysis are an improvement on more traditional modeling approaches as they allow exploration of patterns of victimization experiences. The goal of the current study was to examine associations between patterns of peer victimization in adolescence and both concurrent and longitudinal psychosocial adjustment. Data were included for 3536 youth (49.6% female) in Ethiopia, India, Peru, and Vietnam to examine associations between adolescent peer victimization and indicators of poor psychosocial adjustment. Previously derived latent classes of peer victimization based on youth self report of past-year exposure to nine forms of peer victimization at age 15 were used to predict self-reported emotional difficulties, self-rated health, and subjective wellbeing at ages 15 and 19 while controlling for sex. The findings show that at age 15, victimization was associated with higher emotional difficulties in all settings, lower subjective wellbeing in all except Peru, and lower self-rated health in Vietnam. At follow-up, all associations had attenuated and were largely non-significant. Sensitivity analyses confirmed the robustness of these results. These findings illustrate the multifinality of outcomes of peer victimization, suggesting social and developmental influences for potential pathways of resilience that hold promise for informing interventions and supports in both low and high resource settings. PMID- 30298224 TI - The Consequences of Adolescent Delinquent Behavior for Adult Employment Outcomes. AB - Delinquent behavior is common during adolescence and may disrupt trajectories of labor market attainment. Estimates of the relationship between delinquency and employment are threatened by selection bias, as youth who engage in delinquency often differ substantially from youth who do not. The current study examined the association between adolescents' engagement in serious delinquency and four measures of occupational attainment in young adulthood: unemployment, personal earnings, employer-provided benefits, and occupational earnings. It examined the effect of delinquency independent of between-person differences in a variety of attributes and tested whether the hypothesized relationship was mediated by educational attainment, work experience, disconnectedness from both education and work, or criminal justice sanctioning. This study analyzed data from the first four waves of the National Longitudinal Survey of Adolescent to Adult Health (Add Health), yielding an analytic sample of 14,800 (51% female, mean age 16 years). The Wave 1 Add Health survey was administered in 1994-1995, and Wave 4 of the survey was administered in 2007-2008. The analytic strategy, propensity score weighting, produced estimates that were less biased by differences between youth who had and who had not engaged in delinquent behavior. The study found that delinquency was significantly associated with the likelihood of being unemployed: compared to non-delinquents, delinquents were more likely to be unemployed even after controlling for temporally prior traits and resources, human capital, and criminal justice contact. The results provided more qualified support for hypothesized relationships between delinquency and job quality. The study concluded that offending may result in less fruitful job searches, but once a search results in employment, employed delinquents are not readily discernible from employed non-delinquents in the quality of their jobs. These conclusions contribute to literature on the labor market outcomes of people with histories of adolescent delinquency as they enter young adulthood. PMID- 30298225 TI - Talking Together, Thinking Alone: Relations among Co-Rumination, Peer Relationships, and Rumination. AB - Girls are more likely to engage in rumination, associated with the development of mental health problems, as well as report higher levels of friendship quality, hypothesized to protect against these disorders. The current study examined whether co-rumination may drive simultaneous increases in rumination and changes in friendship quality among adolescents. The project included 360 participants (43% boys), ages 9.8 to 15.8 years, and analyses revealed that co-rumination mediated the link between female sex and both rumination and negative friendship quality. There was also a bidirectional relation between co-rumination and positive friendship quality. These findings highlight several pathways by which co-rumination mediates the relation between sex and both maladaptive (i.e. rumination, negative friendship quality) and adaptive (i.e. positive friendship quality) outcomes. PMID- 30298226 TI - Hypertensive Crisis with Neurological Impairment Mimicking a Guillain-Barre Syndrome: Searching for a Link. AB - Guillain-Barre syndrome (GBS) may be complicated by severe hypertension (HT) and in turns severe HT can occur with neurological damage mimicking a GBS, so that underlying causes should be investigated. We describe a case of a 62-year-old woman presented to the emergency department for hypertensive crisis with symmetric flaccid paralysis, hypotonia and hyporeflexia of both upper and lower limbs. Brain computed tomography, magnetic resonance imaging and lumbar puncture were normal. Laboratory investigations revealed severe hypokalemia, renal failure, liver impairment, rabdomyolysis, metabolic alkalosis, and low plasma renin and aldosterone levels. Continuous potassium replacement led to complete clinical resolution. A detailed history revealed chronic intake of 250 g/day black liquorice. Hypokalaemic muscle weakness may simulate a GBS. When serum potassium level falls below 2.5 mmol/l, rhabdomyolysis may occur. In this clinical case, an apparent mineralocorticoid excess syndrome was induced by chronic ingestion of liquorice. This latter contains the glycyrrhetic acid that inhibits the enzyme 11-beta-hydroxysteroid dehydrogenase enzyme type-2 leading an aldosterone-like effect and causing hypertension, hypokalemia, metabolic alkalosis and low renin values. The clinical presentation is similar to that observed in the primary aldosteronism, but in this syndrome plasma aldosterone levels are low rather than elevated as in primary aldosteronism. Liquorice induced hypertension with severe hypokalemia and rhabdomyolysis is a rare condition and the initial presentation with acute muscle paralysis is still more unusual. Before performing instrumental examinations in middle-aged peoples with hypertension crisis and neurological impairment, a detailed clinical history is mandatory. PMID- 30298227 TI - Short-Term and Mid-Term Results of Minimally Invasive Occlusion of Ventricular Septal Defects via a Subaxillary Approach in a Single Center. AB - This retrospective, single-center study evaluated short-term and mid-term results of minimally invasive surgery to occlude ventricular septal defects (VSDs) using a subaxillary approach. The procedure was performed on 429 children (224 boys, 205 girls; age 2.4 +/- 2.5 years; mean weight 12.7 +/- 10.1 kg) between January 2014 and December 2016 at the Children's Heart Center of Henan Province People's Hospital. An approximately 2-cm subaxillary incision was made between the third and fifth ribs, and the appropriate right atrium or ventricle was punctured under the guidance of transencephalographic echocardiography (TEE). The VSD was then occluded under TEE guidance. The mean size of the VSDs was 4.2 +/- 1.0 mm, and the occluder measured 5.3 +/- 1.3 mm. Asymmetrical occluders were used in 44 patients and symmetrical occluders in 385 patients. The operative time was 60.7 +/- 21.3 min, and time in the intensive care unit was 20.9 +/- 6.5 h. Blood loss was 12.4 +/- 14.4 ml. There were no deaths among these patients. Occluder displacement occurred in two cases. There were no complications (e.g., third degree atrioventricular block, new aortic regurgitation, reoperation for massive bleeding, serious infection). All patients were followed for 6-48 months, during which time there were ten cases of a postoperative residual shunt, which self closed in eight during follow-up. The other two cases are still being followed. No complications occurred during follow-up (e.g., reoperation, aortic regurgitation, atrioventricular block, occluder abscission). Occluding VSDs using the subaxillary approach is safe and effective. Short-term and mid-term results are satisfactory. Further follow-up is required regarding long-term results. PMID- 30298228 TI - Ticks in the Lion City: a preliminary review of the tick fauna of Singapore. AB - To this day, the tick fauna of Singapore remains poorly known. Although several studies of select species have been undertaken within Singapore, much of the information regarding Singaporean ticks is fragmentary. To facilitate future study of this group, the scattered information on Singaporean ticks is synthesised in the present work and includes a preliminary checklist of species reported to occur in Singapore, which comprised 14 species in 5 genera, with confirmed records of Argas pusillus, Amblyomma nitidum, Amblyomma varanense, Haemaphysalis doenitzi, Haemaphysalis nadchatrami, Haemaphysalis semermis, Ixodes granulatus, Rhipicephalus microplus, and Rhipicephalus sanguineus, and unconfirmed reports of Amblyomma cordiferum, Amblyomma geoemydae, Amblyomma helvolum, Amblyomma javanense and Amblyomma testudinarium. PMID- 30298229 TI - Characterisation of cattle anal odour constituents associated with the repellency of Rhipicephalus appendiculatus. AB - Adults of the Brown Ear Tick (Rhipicephalus appendiculatus) have a predilection for feeding inside and around the ears of cattle and other hosts. A previous study has shown that the tick locates the host ears by 'push-pull' deployment of a repellent blend emitted at the anal region and an attractant blend emitted at the ears. Interestingly, the two odours play reverse roles with Rhipicephalus evertsi, which prefer to feed around the anal region. The present study was undertaken to characterize the major constituents of the cattle anal odour and to evaluate their repellence to R. appendiculatus. The anal odour was trapped with reverse-phase C18-bonded silica, Porapak Q and Super Q placed in an oven bag attached at the anal region of the cattle for 6 h. The adsorbents were then removed and extracted with dichloromethane, and the extracted compounds analyzed by linked gas chromatography-mass spectrometry (GC-MS). The major constituents of the odour were o-xylene, 4-hydroxy-4-methyl-2-pentanone, 4-methyl-2 methoxyphenol, ethylbenzene, 2,6,6-trimethyl [1S(1alpha,beta,5alpha)]bicycloheptanes, 5-ethoxydihydro-2(3H)-furanone, 3 methylene-2-pentanone, 5-methyl-2-phenyl-1H-indole, and 3-pentanone. The repellency of the available compounds (o-xylene, 4-hydroxy-4-methyl-2-pentanone, 4-methyl-2-methoxyphenol, ethyl benzene, 3-methylene-2-pentanone, and 3 pentanone) and blends was evaluated using a dual choice tick climbing assay at different doses. The anal odour showed repellence with RD75 of 0.39. Of the compounds tested, 4-methyl-2-methoxyphenol was found to be most repellent (RD75 = 0.56) and 3-pentanone least repellent (RD75 = 622.7). The blend of the six constituents showed RD75 of 0.34, comparable to that of the crude anal odour blend. A series of subtractive bioassays with one constituent of the 6-component blend missing was also carried out. Subtraction of 3-methylpentanone gave the most repellent blend (RD75 = 0.097), whereas subtraction of 4-methylguaiacol gave the least repellent blend (RD75 = 160.7) consistent with the high individual activity of this phenol. The study lays down useful groundwork for on-host deployment of controlled-release of a selected repellent or blend to disrupt the tick's ability to locate its preferred feeding site. PMID- 30298230 TI - A morphological and phylogenetic analysis of Ornithodoros marinkellei (Acari: Argasidae), with additional notes on habitat and host usage. AB - Ornithodoros marinkellei was described from larvae collected on Pteronotus spp. bats in Colombia and Panama. More recently, this tick was reported in the Brazilian Amazon. Because some morphometric differences were observed between O. marinkellei larvae from Colombia and Brazil, it was proposed that further investigations were needed to assess whether the differences could be attributed to intra- or inter-specific polymorphism. Herein, we collected O. marinkellei specimens in the type locality of Colombia, in Brazil, and in a new locality in Nicaragua, expanding the distribution of the species to Nicaragua. Morphometric analysis of larvae and adults, corroborated by a principal component analysis (PCA), indicated that the Brazilian specimens were larger than specimens from Colombia and Nicaragua. Phylogenetic analysis inferred from the mitochondrial 16S rRNA gene showed ticks from Colombia and Nicaragua more genetically related than any of them with ticks from Brazil, although ticks from the three countries grouped in a clade sister to a major clade containing sequences of various Neotropical Ornithodoros species. We concluded that ticks identified as O. marinkellei from Colombia, Nicaragua, and Brazil represent the same taxon, and that the genetic and morphological differences between them are likely to have a geographical bias. We redescribed the nymph of O. marinkellei, which has a vestigial hypostome, probably incompatible with blood feeding. We also report human infestation by O. marinkellei adults. As all reports of O. marinkellei adults have been from hot caves (temperature > 35 degrees C), this abiotic condition could be a limiting factor for the occurrence of this tick species. PMID- 30298231 TI - In search of the vector(s) of Babesia rossi in Nigeria: molecular detection of B. rossi DNA in Rhipicephalus sanguineus sensu lato (Acari: Ixodidae) ticks collected from dogs, circumstantial evidence worth exploring. AB - The brown dog tick Rhipicephalus sanguineus (sensu lato) (Acari: Ixodidae) has a cosmopolitan distribution, is a proven vector of a host of pathogens with emerging evidence incriminating it in the transmission of some others. Specifically it is reputed as the main vector of Babesia vogeli whereas the southern African yellow dog tick Haemaphysalis elliptica, long considered to be H. leachi, is apparently the only proven vector of B. rossi, since the resurrection of the separate species H. elliptica as a member of the leachi-group by Apanaskevich et al. However, recent epidemiological surveys conducted in Nigeria show higher prevalence of B. rossi than B. vogeli infection in dogs most of whom were infested with R. sanguineus and rarely with ticks of the H. leachi group. The discrepancy between tick distribution and Babesia spp. prevalent in dogs stimulated us to investigate the possible role of R. sanguineus (s.l.) in the natural transmission of B. rossi. Out of a total of 66 tick samples identified morphologically and molecularly as R. sanguineus collected from dogs manifesting clinical signs of tick-borne diseases, eight (12%) were positive in nested PCR for Babesia sp. DNA. Sequencing results for these amplified products showed that all of the 18S rDNA sequences (693 bp) were identical to each other, and bore 99.3-99.9% identities with those from other B. rossi isolates accessible in GenBank. None of the ticks harbored the DNA of B. vogeli or B. canis. The possible implications for the detection of B. rossi DNA in R. sanguineus (s.l.) ticks collected from dogs in the epidemiology of B. rossi infection of dogs in Nigeria is highlighted.

PMID- 30298233 TI - Systematic Review and Meta-analysis of Short- versus Long-Acting Granulocyte Colony-Stimulating Factors for Reduction of Chemotherapy-Induced Febrile Neutropenia. AB - INTRODUCTION: Short- and long-acting granulocyte-colony stimulating factors (G CSFs) are approved for the reduction of febrile neutropenia. A systematic literature review was performed to identify randomized controlled trials (RCTs) and non-RCTs reporting the use of G-CSFs following chemotherapy treatment. METHODS: Medline(r)/Medline in-process, Embase(r), and the Cochrane Library were searched for studies published between January 2003 and June 2016. A hand-search of relevant conference proceedings was conducted for meetings held between 2012 and 2016. Eligible studies were restricted to those reporting a direct, head-to head comparison of short- versus long-acting G-CSFs for reduction of chemotherapy induced febrile neutropenia. Risk-of-bias assessments were performed for full publications only. RESULTS: The search strategy yielded 4044 articles for electronic screening. Thirty-six publications were evaluated for the meta analysis: 11 of 12 RCTs and 2 of 24 non-RCTs administered doses of the short acting G-CSF filgrastim for >= 7 days. In RCT studies, there was no statistically significant difference in outcomes of interest between short- and long-acting G CSFs. In non-RCTs, the overall risk was lower with long-acting G-CSF than with short-acting G-CSF for incidence of febrile neutropenia [overall relative risk (RR) = 0.67, P = 0.023], hospitalizations (overall RR = 0.68, P < 0.05), and chemotherapy dose delays (overall RR = 0.68, P = 0.020). CONCLUSIONS: Overall, the weight of evidence from RCTs indicates little difference in efficacy between the short- and long-acting G-CSFs if dosed according to recommended guidelines. There is some evidence for greater efficacy for long-acting G-CSFs in non-RCTs, which may be a result of under-dosing of short-acting G-CSFs in general practice in real-world usage.

AB - What do we think about when we mind wander and where do these thoughts come from? We tested the idea that semantically rich stimuli yield patterns of mind wandering that are closely coupled with the stimuli compared to being more internally triggered. We analyzed the content of 949 self-reported zone outs (1218 thoughts) and 519 of their triggers from 88 participants who read an instructional text and watched a film for 20 min each. We found that mind wandering associated with memory retrieval was more frequent than prospection and introspection across both stimuli. Over 70% of autobiographical and semantic memory retrievals were triggered by the content of the stimuli, compared to around 30% for prospective and introspective thoughts. Further, latent semantic analysis revealed that semantic and unspecific memories were more "semantically" similar to their triggers than prospective and introspective thoughts, suggesting that they arise from spontaneous associations with the stimulus. These findings suggest a re-evaluation of how internal concerns and the external world give rise to mind wandering and emphasize the importance of studying mind wandering in semantically rich contexts akin to much of the real world.

PMID- 30298236 TI - Is the genetic variability of Cathepsin B important in the pathogenesis of Blastocystis spp.? AB - The potential role of Blastocystis as a pathogen is controversial because it is found in both symptomatic and asymptomatic carriers. Since Cathepsin B has been identified as a main virulence factor that contributes to the pathogenesis of this parasite, the purpose of this study was to analyze the genetic polymorphisms of cathepsin B from Blastocystis from patients with irritable bowel syndrome and from asymptomatic carriers. DNA from fecal samples of both groups, which were previously genotyped by 18S sequencing, was used to amplify a fragment of the cathepsin B gene. Phylogenetic reconstructions were performed and some genetic population indexes were obtained. Amplicons of 27 samples (15 cases, 10 controls, and two commercial ATCC strains) were obtained and analyzed. Phylogenetic reconstructions using nucleotides or inferred amino acid sequences did not separate between cases or controls or among subtypes. Regarding the values of genetic variability, we found that the haplotype and nucleotide diversity indexes of cathepsin B from cases and controls were similar to the values of 18S from controls. By contrast, 18S from cases showed low variability, suggesting that the genetic variability of cathepsin B was not related to the symptomatology of Blastocystis carriers. However, since no polymorphisms related to cases or controls were found, it is logical to assume that the potential damage caused by Blastocystis in situ may be due to unclear mechanisms of Cathepsin B regulation and expression that should be studied in future studies.

AB - The Patagonian seabass Acanthistius patachonicus (Jenyns, 1840) (Serranidae) is a marine fish valued for commercial and sport fisheries from Argentina. We report a new myxosporean (Cnidaria: Myxozoa) infecting the urinary system of the Patagonian seabass from San Antonio Bay, San Matias Gulf, on the Atlantic Ocean. The mature myxospores were subspherical, 8.2-11.0 MUm * 7.9-11.0 MUm and 7.7-9.0 MUm in thickness; two subspherical polar capsules, 2.4-3.8 MUm * 2.3-3.6 MUm, with 3 to 4 turns of the polar tubule; openings on different valves in almost opposite directions. Ornamented shell valves exhibited 17-20 concentrically organized surface ridges. SSU rDNA phylogenetics analyses placed the new species in the freshwater urinary tract clade, clustering in a clade formed by Myxobilatus gasterostei (Parisi, 1912), Acauda hoffmani Whipps, 2011, and other Ortholinea spp. Based on spore morphology, site of infection, and molecular data, we described this myxozoan as Ortholinea concentrica n. sp. PMID- 30298238 TI - Neural correlates of proactive and reactive inhibition of saccadic eye movements. AB - Although research on goal-directed, proactive inhibitory control (IC) and stimulus-driven, reactive IC is growing, no previous study has compared proactive IC in conditions of uncertainty with regard to upcoming inhibition to conditions of certain upcoming IC. Therefore, we investigated effects of certainty and uncertainty on behavior and blood oxygen level dependent (BOLD) signal in proactive and reactive IC. In two studies, healthy adults performed saccadic go/no-go and prosaccade/antisaccade tasks. The certainty manipulation had a highly significant behavioral effect in both studies, with inhibitory control being more successful under certain than uncertain conditions on both tasks (p <= 0.001). Saccadic go responses were significantly less efficient under conditions of uncertainty than certain responding (p < 0.001). Event-related functional magnetic resonance imaging (fMRI) (one study) revealed a dissociation of certainty- and uncertainty-related proactive inhibitory neural correlates in the go/no-go task, with lateral and medial prefrontal and occipital cortex showing stronger deactivations during uncertainty than during certain upcoming inhibition, and lateral parietal cortex being activated more strongly during certain upcoming inhibition than uncertainty or certain upcoming responding. In the antisaccade task, proactive BOLD effects arose due to stronger deactivations in uncertain response conditions of both tasks and before certain prosaccades than antisaccades. Reactive inhibition-related BOLD increases occurred in inferior parietal cortex and supramarginal gyrus (SMG) in the go/no-go task only. Proactive IC may imply focusing attention on the external environment for encoding salient or alerting events as well as inhibitory mechanisms that reduce potentially distracting neural processes. SMG and inferior parietal cortex may play an important role in both proactive and reactive IC of saccades.

AB - Purpose The articles in this special section examine opportunities for early intervention that is intended to retain the jobs of workers who have medical conditions that could put them at risk of prolonged work disability. Methods The first three articles examine options for analyzing various types of disability claims data for targeting early intervention; the fourth article provides new information from 50 case studies on how employers decide to invest in the retention of individual workers. Results Together, the four articles demonstrate that there may be an opportunity to positively affect longer-term outcomes for workers with medical conditions. This would be accomplished by building and expanding on existing systems in order to efficiently identify, and provide timely support to, workers with medical conditions in a critical period during which the decisions and actions of various stakeholders, including the workers themselves, may have a major influence on these outcomes. Conclusions Forthcoming opportunities to develop, implement, and test evidence-based interventions to promote job retention can provide further insight into the value of the options described in the articles. PMID- 30298241 TI - Self-Stigma Reduction Interventions for People Living with HIV/AIDS and Their Families: A Systematic Review. AB - Stigma is a primary concern for people living with human immunodeficiency virus (HIV)/AIDS (PLWHA), and has great impact on their and their family members' health. While previous reviews have largely focused on the public stigma, this systematic review aims to evaluate the impact of HIV/acquired immunodeficiency syndrome (AIDS)-related self-stigma reduction interventions among PLWHA and their families. A literature search using eight databases found 23 studies meeting the inclusion criteria. Five types of intervention approaches were identified: (1) psycho-educational intervention, (2) supportive intervention for treatment adherence (antiretroviral therapy), (3) psychotherapy intervention, (4) narrative intervention, and (5) community participation intervention. Overall, the reviewed articles suggested a general trend of promising effectiveness of these interventions for PLWHA and their family members. Psycho-educational interventions were the main approach. The results highlighted the need for more interventions targeting family members of PLWHA, and mixed-methods intervention studies. PMID- 30298242 TI - Test Result Management Practices of Canadian Internal Medicine Physicians and Trainees. AB - BACKGROUND: Missed test results are a cause of medical error. Few studies have explored test result management in the inpatient setting. OBJECTIVE: To examine test result management practices of general internal medicine providers in the inpatient setting, examine satisfaction with practices, and quantify self reported delays in result follow-up. DESIGN: Cross-sectional survey. PARTICIPANTS: General internal medicine attending physicians and trainees (residents and medical students) at three Canadian teaching hospitals. MAIN MEASURES: Methods used to track test results; satisfaction with these methods; personal encounters with results respondents "wish they had known about sooner." KEY RESULTS: We received surveys from 33/51 attendings and 99/108 trainees (response rate 83%). Only 40.9% of respondents kept a record of all tests they order, and 50.0% had a system to ensure ordered tests were completed. Methods for tracking test results included typed team sign-out lists (40.7%), electronic health record (EHR) functionality (e.g., the electronic "inbox") (38.9%), and personal written or typed lists (14.8%). Almost all trainees (97.9%) and attendings (81.2%) reported encountering at least one test result they "wish they had known about sooner" in the past 2 months (p = 0.001). A higher percentage of attendings kept a record of tests pending at hospital discharge compared to trainees (75.0% vs. 35.7%, p < 0.001), used EHR functionality to track tests (71.4% vs. 27.5%, p = 0.004), and reported higher satisfaction with result management (42.4% vs. 12.1% satisfied or very satisfied, p < 0.001). CONCLUSIONS: Canadian physicians report an array of problems managing test results in the inpatient setting. In the context of prior studies from the outpatient setting, our study suggests a need to develop interventions to prevent missed results and avoid potential patient harms. PMID- 30298240 TI - The Impact of Interictal Discharges on Performance. AB - PURPOSE OF REVIEW: Our purpose is to review evidence relating to the concept that interictal epileptiform discharges (IEDs) impair brain performance. RECENT FINDINGS: Sophisticated measures of motor and cognitive performance have clarified older observations, confirming that in both animals and humans, IEDs affect aspects of performance, IED morphology, frequency, anatomical distribution, and duration matter. However, we now know that it is difficult to draw a line between IEDs and seizures, not only by electrical criteria but even by metabolic and molecular measures. IEDs impair performance acutely and probably chronically. Thus, there are good theoretical reasons for suppressing them, but no consensus has been reached on how much effort this deserves. Many antiepileptic medications effective for control of clinical seizures have little effect on IEDs. Better methods of measuring outcomes may allow selection of individual patients for whom treatment aimed at IEDs is worthwhile. PMID- 30298243 TI - Fragments of the second transmembrane helix of three G-protein-coupled receptors: comparative synthetic, structural and conformational studies. AB - We compared the synthesis and structural/conformational details of the (66-97) segments of the second transmembrane helix of AT1, MAS and B2, all of which belong to the class of G-protein-coupled receptors (GPCR). Step-by-step monitoring of the coupling reactions during the growth of these transmembrane peptides revealed that the increase in the level of difficulty started at the 6 10 regions of the sequence. Possibly due to their long and hydrophobic sequences, the final estimated synthesis yields decreased progressively by up to 20-25%. Analytical high pressure liquid chromatography showed that the hydrophobicity indexes of each TM-8, -16, -24 and -32 segments correlated linearly with their retention time. Microscopic measurements of peptide-resin beads indicated that, in general, dichloromethane and dimethylsulfoxide were the best solvents for solvating resin beads in the initial and final stages of the synthesis, respectively. Results from electron paramagnetic resonance experiments with Toac (2, 2, 6, 6-tetramethylpiperidine-1-oxyl-4-amino-4-carboxylic acid) spin-labeled peptide resins revealed that the level of peptide chain mobility throughout the polymer network was in agreement with their swelling data measured in different solvents. Initial results regarding conformational features determined by circular dichroism (CD) spectra revealed typical alpha-helicoidally structures for MAS and B2 TM32 fragments when in more than roughly 30% (v/v) trifluoroethanol (TFE). In contrast, the AT1-TM32 segment revealed CD spectra, more representatives of a mixture of other secondary helical conformers, regardless of the amount of TFE. These findings observed in different aspects of these receptors' fragments support further investigations of GPCR-type macromolecules.

AB - A large portion of the earth's biomass resides in the subsurface and recent studies have expanded our knowledge of indigenous microbial life. Advances in the field of metagenomics now allow analysis of microbial communities from low biomass samples such as deep (>2.5 km) shale core samples. Here we present protocols for the best practices in contamination control, handling core material, extraction of nucleic acids, and low-input library preparation for subsequent metagenomic sequencing. PMID- 30298245 TI - Freshwater Viromes: From Sampling to Evaluation. AB - There are a number of options available to researchers who wish to collect and analyze viral metagenomes (viromes) from environmental samples. Here we describe a laboratory procedure for generation of viromes from freshwater samples, specifically targeting dsDNA bacteriophages. We also discuss methods for bioinformatic analysis of the resulting data. PMID- 30298246 TI - Characterization of Eukaryotic Microbiome Using 18S Amplicon Sequencing. AB - With the advent of low-cost, high-throughput sequencing, taxonomic profiling of complex microbial communities through 16S rRNA marker gene surveys has received widespread interest, uncovering a wealth of information concerning the bacterial composition of microbial communities, as well as their association with health and disease. On the other hand, little is known concerning the eukaryotic components of microbiomes. Such components include single-celled parasites and multicellular worms that are known to adversely impact the health of millions of people worldwide. Current molecular methods to detect eukaryotic microbes rely on the use of directed PCR analyses that are limited by their inability to inform beyond the taxon targeted. With increasing interest to develop equivalent marker based surveys as used for bacteria, this chapter presents a stepwise protocol to characterize the diversity of eukaryotic microbes in a sample, using amplicon sequencing of hypervariable regions in the eukaryotic 18S rRNA gene. PMID- 30298247 TI - Culture and Molecular Profiling of the Respiratory Tract Microbiota. AB - Microbiome research of host-associated communities has been advanced recently through improvements in sequencing technologies and bioinformatic methods. Traditional microbiological culture, when combined with molecular techniques, can provide a sensitive platform to comprehensively study the airway microbiota. Here we describe the culture methods necessary to capture a large proportion of the airway microbiota and molecular methods for profiling bacterial communities through the 16S rRNA gene, which, when combined, offer a more complete picture of the diversity of airway microbial communities than either method alone. PMID- 30298248 TI - Methods and Strategies to Examine the Human Breastmilk Microbiome. AB - It has recently been discovered that breastmilk is not sterile, but contains a vast array of microbes, known collectively as the breastmilk microbiome. The breastmilk microbiome field is in its infancy, but over the last decade, our understanding of the microbial communities that inhabit the human body has increased exponentially, due in large part to novel next-generation sequencing technologies. These culture-independent, high-throughput molecular technologies have allowed biologists to investigate the entirety of microbiota present in breastmilk, which was previously poorly known. These approaches are novel and the methodologies surrounding the exploration of the breastmilk microbiota remain in flux. The objectives of this chapter are to outline what is known thus far and detail the optimal methods and strategies to conducting a breastmilk microbiome study from subject recruitment and milk collection to DNA extraction, high throughput sequencing and bioinformatics analyses. PMID- 30298249 TI - Quantification of Vitamin B12-Related Proteins in Marine Microbial Systems Using Selected Reaction Monitoring Mass Spectrometry. AB - Mass spectrometry-based proteomic approaches to studying microbial systems enable assessment of taxonomically resolved functional capacity. A subset of these proteomic approaches are absolutely quantitative, enabling comparisons of protein expression patterns between different studies and across environments. This chapter outlines a method for applying quantitative assays in marine microbial communities, using proteins involved in vitamin B12 (cobalamin) utilization and production as specific examples. This approach involves identifying important protein targets, determining taxonomic resolution of the required assays, identifying suitable peptides, developing and optimizing liquid chromatography selected reaction monitoring mass spectrometry assays (LC-SRM-MS), and processing the resulting data. Implementing the method outlined here results in measurements (fmol diagnostic peptide per MUg of total bulk protein) that, in this case, define the nutritional status of microbial community members with respect to vitamin B12, and are comparable across and between marine microbial systems. PMID- 30298250 TI - Single-Cell Genomics of Microbial Dark Matter. AB - Single-cell genomics allows bypassing the culturing step and to directly access environmental microbes one cell at a time. The method has been successfully applied to explore archaeal and bacterial candidate phyla, referred to as microbial dark matter. Here I summarize the single-cell genomics workflow, including sample preparation and preservation, high-throughput fluorescence activated cell sorting, cell lysis and amplification of environmental samples. Furthermore I describe phylogenetic screening based on 16S rRNA genes and suggest a suitable library preparation and sequencing approach. PMID- 30298251 TI - 16S rRNA Gene Analysis with QIIME2. AB - Microbial marker-gene sequence data can be used to generate comprehensive taxonomic profiles of the microorganisms present in a given community and for other community diversity analyses. The process of going from raw gene sequences to taxonomic profiles or diversity measures involves a series of data transformations performed by numerous computational tools. This includes tools for sequence quality checking, denoising, taxonomic classification, alignment, and phylogenetic tree building. In this chapter, we demonstrate how the Quantitative Insights Into Microbial Ecology version 2 (QIIME2) software suite can simplify 16S rRNA marker-gene analysis. We walk through an example data set extracted from the guts of bumblebees in order to show how QIIME2 can transform raw sequences into taxonomic bar plots, phylogenetic trees, principal co ordinates analyses, and other visualizations of microbial diversity. PMID- 30298252 TI - Processing a 16S rRNA Sequencing Dataset with the Microbiome Helper Workflow. AB - Sequencing microbiome samples has recently become a fast and cost-effective method to taxonomically profile communities. The growing interest in analyzing microbial sequencing data has attracted many new researchers to the field. Here, we present a straightforward bioinformatic pipeline that aims to streamline the processing of 16S rRNA sequencing data. This workflow is part of the larger project called Microbiome Helper (Comeau et al. mSyst 2:e00127-16, 2017), which includes other bioinformatic workflows, tutorials, and scripts available here: https://github.com/mlangill/microbiome_helper/wiki . PMID- 30298253 TI - Normalization of Microbiome Profiling Data. AB - Normalization is a term that is often used but rarely defined and poorly understood. The number of choices of normalization procedure is large-some are inappropriate or inadmissible-and all are narrowly relevant to a specific analysis that depends on both the nature of the data and the question being asked. This chapter describes key definitions of normalization as they apply in metagenomics, mainly for taxonomic profiling data; while also demonstrating specific, reproducible examples of normalization procedures in the context of analysis techniques for which they were intended. The analysis and graphics code is distributed as a supplemental companion to this chapter so that the motivated reader can re-use it on new data. PMID- 30298254 TI - Predicting the Functional Potential of the Microbiome from Marker Genes Using PICRUSt. AB - Marker-gene sequencing is a cost-effective method of taxonomically profiling microbial communities. Unlike metagenomic approaches, marker-gene sequencing does not provide direct information about the functional genes that are present in the genomes of community members. However, by capitalizing on the rapid growth in the number of sequenced genomes, it is possible to infer which functions are likely associated with a marker gene based on its sequence similarity with a reference genome. The PICRUSt tool is based on this idea and can predict functional category abundances based on an input marker gene. In brief, this method requires a reference phylogeny with tips corresponding to taxa with reference genomes as well as taxa lacking sequenced genomes. A modified ancestral state reconstruction (ASR) method is then used to infer counts of functional categories for taxa without reference genomes. The predictions are written to pre-calculated files, which can be cross-referenced with other datasets to quickly generate predictions of functional potential for a community. This chapter will give an in-depth description of these methods and describe how PICRUSt should be used. PMID- 30298255 TI - Metagenome Assembly and Contig Assignment. AB - The recent development of metagenomic assembly has revolutionized metagenomic data analysis, thanks to the improvement of sequencing techniques, more powerful computational infrastructure and the development of novel algorithms and methods. Using longer assembled contigs rather than raw reads improves the process of metagenomic binning and annotation significantly, ultimately resulting in a deeper understanding of the microbial dynamics of the metagenomic samples being analyzed. In this chapter, we demonstrate a typical metagenomic analysis pipeline including raw read quality evaluation and trimming, assembly and contig binning. Alternative tools that can be used for each step are also discussed. PMID- 30298256 TI - From RNA-seq to Biological Inference: Using Compositional Data Analysis in Meta Transcriptomics. AB - The proper analysis of high-throughput sequencing datasets of mixed microbial communities (meta-transcriptomics) is substantially more complex than for datasets composed of single organisms. Adapting commonly used RNA-seq methods to the analysis of meta-transcriptome datasets can be misleading and not use all the available information in a consistent manner. However, meta-transcriptomic experiments can be investigated in a principled manner using Bayesian probabilistic modeling of the data at a functional level coupled with analysis under a compositional data analysis paradigm. We present a worked example for the differential functional evaluation of mixed-species microbial communities obtained from human clinical samples that were sequenced on an Illumina platform. We demonstrate methods to functionally map reads directly, conduct a compositionally appropriate exploratory data analysis, evaluate differential relative abundance, and finally identify compositionally associated (constant ratio) functions. Using these approaches we have found that meta-transcriptomic functional analyses are highly reproducible and convey significant information regarding the ecosystem. PMID- 30298257 TI - Subsampled Assemblies and Hybrid Nucleotide Composition/Differential Coverage Binning for Genome-Resolved Metagenomics. AB - Metagenomic analyses for reconstruction of genomes from mixed microbial community datasets now routinely allow rapid, accurate genome recovery for tens to hundreds of organisms from environmental samples. This chapter provides a step-by-step protocol for reconstructing genomes from metagenomic datasets, with a focus on the most abundant community members. Subsampling assembly approaches are implemented to improve assembly of abundant genome sequences, an iterative process that targets progressively less abundant populations and improves total community representation in the final merged assembly. A hybrid approach to genome binning is described, combining differential coverage information from a series of metagenomic samples with nucleotide composition information. This approach strengthens binning through application of multiple independent variables for contig clustering. Genome curation through error correction and gap closure leads to high-quality draft genomes, and, for some community members, closed and complete genome sequences reconstructed directly from environmental samples. PMID- 30298258 TI - Transkingdom Networks: A Systems Biology Approach to Identify Causal Members of Host-Microbiota Interactions. AB - Improvements in sequencing technologies and reduced experimental costs have resulted in a vast number of studies generating high-throughput data. Although the number of methods to analyze these "omics" data has also increased, computational complexity and lack of documentation hinder researchers from analyzing their high-throughput data to its true potential. In this chapter we detail our data-driven, transkingdom network (TransNet) analysis protocol to integrate and interrogate multi-omics data. This systems biology approach has allowed us to successfully identify important causal relationships between different taxonomic kingdoms (e.g., mammals and microbes) using diverse types of data. PMID- 30298259 TI - Constructing and Analyzing Microbiome Networks in R. AB - Microbiomes are complex microbial communities whose structure and function are heavily influenced by microbe-microbe and microbe-host interactions mediated by a range of mechanisms, all of which have been implicated in the modulation of disease progression and clinical outcome. Therefore, understanding the microbiome as a whole, including both the complex interplay among microbial taxa and interactions with their hosts, is essential for understanding the spectrum of roles played by microbiomes in host health, development, dysbiosis, and polymicrobial infections. Network theory, in the form of systems-oriented, graph theoretical approaches, is an exciting holistic methodology that can facilitate microbiome analysis and enhance our understanding of the complex ecological and evolutionary processes involved. Using network theory, one can model and analyze a microbiome and all its complex interactions in a single network. Here, we describe in detail and step by step, the process of building, analyzing and visualizing microbiome networks from operational taxonomic unit (OTU) tables in R and RStudio, using several different approaches and extensively commented code snippets. PMID- 30298260 TI - Bayesian Inference of Microbial Community Structure from Metagenomic Data Using BioMiCo. AB - Microbial samples taken from an environment often represent mixtures of communities, where each community is composed of overlapping assemblages of species. Such data represent a serious analytical challenge, as the community structures will be present as complex mixtures, there will be very large numbers of component species, and the species abundance will often be sparse over samples. The structure and complexity of these samples will vary according to both biotic and abiotic factors, and classical methods of data analysis will have a limited value in this setting. A novel Bayesian modeling framework, called BioMiCo, was developed to meet this challenge. BioMiCo takes abundance data derived from environmental DNA, and models each sample by a two-level mixture, where environmental OTUs contribute community structures, and those structures are related to the known biotic and abiotic features of each sample. The model is constrained by Dirichlet priors, which induces compact structures, minimizes variance, and maximizes model interpretability. BioMiCo is trained on a portion of the data, and once trained a BioMiCo model can be employed to make predictions about the features of new samples. This chapter provides a set of protocols that illustrate the application of BioMiCo to real inference problems. Each protocol is designed around the analysis of a real dataset, which was carefully chosen to illustrate specific aspects of real data analysis. With these protocols, users of BioMiCo will be able to undertake basic research into the properties of complex microbial systems, as well as develop predictive models for applied microbiomics. PMID- 30298261 TI - Analyzing Metabolic Pathways in Microbiomes. AB - Understanding the metabolic activity of a microbial community, at both the level of the individual microbe and the whole microbiome, provides fundamental biological, biochemical, and clinical insights into the nature of the microbial community and interactions with their hosts in health and disease. Here, we discuss a method to examine the expression of metabolic pathways in microbial communities using data from metatranscriptomic next-generation sequencing data. The methodology described here encompasses enzyme function annotation, differential enzyme expression and pathway enrichment analyses, and visualization of metabolic networks with differential enzyme expression levels. PMID- 30298262 TI - Sparse Treatment-Effect Model for Taxon Identification with High-Dimensional Metagenomic Data. AB - To identify disease-associated taxa is an important task in metagenomics. To date, many methods have been proposed for feature selection and prediction. However, those proposed methods are either using univariate (generalized) regression approaches to get the corresponding P-values without considering the interactions among taxa, or using lasso or L0 type sparse modeling approaches to identify taxa with best predictions without providing P-values. To the best of our knowledge, there are no available methods that consider taxon interactions and also generate P-values.In this paper, we propose a treatment-effect model for identifying taxa (STEMIT) and performing statistical inference with high dimensional metagenomic data. STEMIT will provide a P-value for a taxon through a two-step treatment-effect maximization. It will provide causal inference if the study is a clinical trial. We first identify taxa associated with the treatment effect variable and the targeting feature with sparse modeling, and then estimate the P-value of the targeting gene with ordinary least square (OLS) regression. We demonstrate that the proposed method is efficient and can identify biologically important taxa with a real metagenomic data set. The software for L0 sparse modeling can be downloaded at https://cran.r-project.org/web/packages/l0ara/ . PMID- 30298263 TI - Semantic memories prime autobiographical memories: General implications and implications for everyday autobiographical remembering. AB - This study investigated the idea that semantic memory activation causes the activation of associated autobiographical memories (e.g., reading the word summer activates knowledge representations in semantic memory, as well as associated personal memories about summer in autobiographical memory). We tested this semantic-autobiographical memory priming hypothesis in three experiments. In Experiment 1, participants were primed with concepts (e.g., summer) on a familiarity task and were then given a word-cue voluntary autobiographical memory task. In support of the hypothesis, the results showed that primed participants had more autobiographical memories overlapping with the primed concepts than control participants. In Experiment 2, participants were similarly primed, but in this case they were given a measure of involuntary autobiographical memory (i.e., Schlagman and Kvavilashvili's (Memory & Cognition, 36, 920-932, 2008) vigilance task). The results of this experiment also supported the semantic autobiographical memory-priming hypothesis. Experiment 3 ruled out an alternative possibility (i.e., that autobiographical memory processing had occurred in the word familiarity task) by showing that semantic-autobiographical priming had resulted from a priming task (lexical decision) where autobiographical memory processing was unlikely. The implications of these findings are discussed. PMID- 30298264 TI - The Tool for the Automatic Analysis of Cohesion 2.0: Integrating semantic similarity and text overlap. AB - This article introduces the second version of the Tool for the Automatic Analysis of Cohesion (TAACO 2.0). Like its predecessor, TAACO 2.0 is a freely available text analysis tool that works on the Windows, Mac, and Linux operating systems; is housed on a user's hard drive; is easy to use; and allows for batch processing of text files. TAACO 2.0 includes all the original indices reported for TAACO 1.0, but it adds a number of new indices related to local and global cohesion at the semantic level, reported by latent semantic analysis, latent Dirichlet allocation, and word2vec. The tool also includes a source overlap feature, which calculates lexical and semantic overlap between a source and a response text (i.e., cohesion between the two texts based measures of text relatedness). In the first study in this article, we examined the effects that cohesion features, prompt, essay elaboration, and enhanced cohesion had on expert ratings of text coherence, finding that global semantic similarity as reported by word2vec was an important predictor of coherence ratings. A second study was conducted to examine the source and response indices. In this study we examined whether source overlap between the speaking samples found in the TOEFL-iBT integrated speaking tasks and the responses produced by test-takers was predictive of human ratings of speaking proficiency. The results indicated that the percentage of keywords found in both the source and response and the similarity between the source document and the response, as reported by word2vec, were significant predictors of speaking quality. Combined, these findings help validate the new indices reported for TAACO 2.0. PMID- 30298265 TI - The "Small World of Words" English word association norms for over 12,000 cue words. AB - Word associations have been used widely in psychology, but the validity of their application strongly depends on the number of cues included in the study and the extent to which they probe all associations known by an individual. In this work, we address both issues by introducing a new English word association dataset. We describe the collection of word associations for over 12,000 cue words, currently the largest such English-language resource in the world. Our procedure allowed subjects to provide multiple responses for each cue, which permits us to measure weak associations. We evaluate the utility of the dataset in several different contexts, including lexical decision and semantic categorization. We also show that measures based on a mechanism of spreading activation derived from this new resource are highly predictive of direct judgments of similarity. Finally, a comparison with existing English word association sets further highlights systematic improvements provided through these new norms. PMID- 30298266 TI - Quantification of nonverbal synchrony using linear time series analysis methods: Lack of convergent validity and evidence for facets of synchrony. AB - Nonverbal synchrony describes coordination of the nonverbal behavior of two interacting partners. Additionally, it seems to be important in human interactions, such as during psychotherapy. Currently, there are several options for the automated determination of synchrony based on linear time series analysis methods (TSAMs). However, investigations into whether the different methods measure the same construct have been missing. In this study, N = 84 patient therapist dyads were videotaped during psychotherapy sessions. Motion energy analysis was used to assess body movements. We applied seven different TSAMs and recorded multiple output scores (average synchrony, maximum synchrony, and frequency of synchrony; in total, N = 16 scores). Convergent validity was examined using correlations of the output scores and exploratory factor analysis. Additionally, two criterion-based validations were conducted: investigations of concordant validity with a more generalized nonlinear method, and of the predictive validity of the synchrony scores for improvement in interpersonal problems at the end of therapy. We found that the synchrony measures only partially correlated with each other. The factor analysis did not support a common-factor model. A three-factor model with a second-order synchrony variable showed the best fit for eight of the selected synchrony scores. Only some synchrony scores were able to predict improvement at the end of therapy. We concluded that the considered TSAMs do not measure the same synchrony construct, but different facets of synchrony: the strength of synchrony of the total interaction, the strength of synchrony during synchronization intervals, and the frequency of synchrony. PMID- 30298267 TI - Interpersonal Stress Severity Longitudinally Predicts Adolescent Girls' Depressive Symptoms: the Moderating Role of Subjective and HPA Axis Stress Responses. AB - In recent decades, stress response models of adolescent depression have gained attention, but it remains unclear why only certain adolescents are vulnerable to the depressogenic effects of stress while others are not. Building on evidence that affective and physiological responses to stress moderate the impact of stress exposure on depression, the current study examined whether the interaction between severity of interpersonal stress, subjective affective reactivity, and hypothalamic-pituitary-adrenal (HPA) axis reactivity to an acute, in-vivo psychosocial stressor prospectively predicted depressive symptoms nine months later. Hypotheses were examined with a clinically-oversampled group of 182 adolescent girls (aged 12-16) to ensure an examination of the widest possible range of risk. Self-report measures of affect and salivary cortisol samples were collected before and after an in-vivo stress task to assess affective reactivity and HPA axis reactivity, respectively. Severity of interpersonal stress between baseline and nine months was assessed using a semi-structured interview and was objectively coded for severity and content theme (i.e., interpersonal vs. non interpersonal). Results indicate that experiences of severe interpersonally themed stress predict elevated levels of depressive symptoms longitudinally only for adolescent girls with elevated affective reactivity to stress, and suggest that these deleterious effects of stress are most exacerbated for girls with elevated physiological responses to stress. Findings suggest that it may be critical to examine both affective and physiological stress responses when assessing risk for depression in adolescents.

PMID- 30298271 TI - [Positioning of external pelvic stabilization devices in patients with multiple injuries : Retrospective computed tomographic evaluation]. AB - BACKGROUND: Severe hemorrhage is a dreaded complication of pelvic fractures. It has a significant impact on early trauma-associated mortality. Hemorrhage that is secondary to pelvic fractures can be reduced by external stabilization devices. Despite the commercial availability of many different systems, they are infrequently used. The aim of this computed tomography (CT) study was to examine the use of external pelvic stabilization devices. METHODS: Between 1 January 2011 and 31 December 2015 a total of 982 images produced in CT trauma scans at a level 1 trauma centre were retrospectively examined with respect to the presence of external pelvic stabilizers. The type of device applied, its actual position including deviation from optimal position as well as pelvic parameters and complications were determined. RESULTS: In 67 out of 982 patients (6.82%) with suspected multiple trauma, an external pelvic stabilizer was employed. In 41.8% the devices were not placed in concordance with prevailing scientific knowledge, 53.73% of devices did not comply with the manufacturer's instructions and 51.85% of systems with pneumatic cuffs caused significant malrotation. In one patient the cuff induced hypoperfusion of the leg but without further sequelae. CONCLUSION: While the prehospital use of pelvic slings is increasing, misplacement is very common. Especially inconsistencies between manufacturers' manuals and current scientific knowledge warrant further improvement. In systems with pneumatic cuffs malrotation of the device is common and clinically relevant. Hypoperfusion of the lower extremities is possible and should be taken into account when employing these devices.

AB - Delirium is the most common form of cerebral dysfunction in intensive care patients and is a medical emergency that must be avoided or promptly diagnosed and treated. According to current knowledge the development of delirium seems to be caused by an interplay between increased vulnerability (predisposition) and simultaneous exposure to delirogenic factors. Since delirium is often overlooked in the clinical routine, a continuous screening for delirium should be performed. Due to the close connection between delirium, agitation and pain, sedation and analgesia must be evaluated at least every 8 h analogous to delirium screening. According to current knowledge, a multifactorial and multiprofessional approach is favored in the prevention and treatment of delirium. Non-pharmaceutical interventions through early mobilization, reorientation, sleep improvement, adequate pain therapy and avoidance of polypharmacy are of great importance. Depending on the clinical picture, different substances are used in symptom oriented drug treatment of delirium. In order to achieve these diagnostic and therapeutic goals, an interdisciplinary treatment team consisting of intensive care, intensive care physicians, ward pharmacists, physiotherapists, nutrition specialists and psychiatrists is necessary in order to meet the requirements of the patient and their relatives.

AB - A high-performance liquid chromatography method with methyl acetoacetate derivatization via the Hantzsch reaction was developed for the analysis of formaldehyde (HCHO) in several water samples. Under optimized conditions, HCHO was detected within 4 min and was not affected by excessive derivatization reagents. The calibration curve constructed from the peak height of HCHO was linear, with a correlation coefficient of 0.9998. The relative standard deviation of the peak height from ten replicates was 0.29%. The detection and quantitative limits were 0.96 ug/L and 3.16 ug/L, respectively. A recovery test of HCHO was performed to compare the developed method with the official analysis method (DNPH method). The developed method was used to determine the HCHO levels in several water samples (tap water, river water, and waste water).

However, different thresholds in urine output (UO) have raised discussion as to the clinical importance of a transiently reduced UO of less than 0.5 ml/kg/h lasting for at least 6 h. While some studies have demonstrated that isolated oliguria without a concomitant increase in serum creatinine is associated with higher mortality rates, different underlying pathophysiological mechanisms suggest varied clinical importance of reduced UO, as some episodes of oliguria may be fully reversible. We aim to explore the clinical relevance of oliguria in critically ill patients and propose a clinical pathway for the diagnostic and therapeutic management of an oliguric, critically ill patient.

AB - The Yangtze River drainage basins are China's most important economic development zones and also the locations of several large-scale fluorine chemical industries. In order to reveal the contribution from the tributaries at the dividing point between the middle and lower reaches of the Yangtze River with respect to perfluorinated substances (PFASs), 17 PFAS compounds in surface water, groundwater, and tap water samples were analyzed in the tributary system of the Jiujiang section of the Yangtze River. The total concentrations of PFASs in the surface waters ranged from 7.8 to 586.2 ng/L. High proportion of short-chain compound PFBS in surface waters in Nanchang City, Poyang Lake, and the Yangtze River was observed which is likely of WWTPs' origin. PMID- 30298275 TI - Integrated Biomarker Responses in Livers of the Pale Chub Zacco platypus for Risk Assessment of a Stream Contaminated by Wastewater Effluents. AB - We evaluated the effects of wastewater effluents on pale chub (Zacco platypus) in a contaminated stream by integrating genotoxic, oxidative stress, histological, and physiological biomarkers. The metal pollution index indicated higher pollution loads at downstream sites (DS1 and DS2) compared with the upstream reference site. Significantly higher nuclear abnormality confirmed the existence of genotoxicity (p < 0.05) at downstream sites. Antioxidant activity (catalase and glutathione S-transferase) and lipid peroxidation levels in livers of Z. platypus were also significantly higher at the DS1 site (p < 0.05). The liver somatic index was also influenced, with abnormal histological alterations in the liver, possibly caused by heavy metal accumulation (Cd, Co, Cr, Mn, Ni, and Pb). The integrated biomarker response value was the highest at DS1 (13.74) followed by DS2 (1.94), indicating that wastewater effluents had the potential to cause adverse effects on Z. platypus inhabiting receiving stream. PMID- 30298276 TI - Is the dual-task cost of walking and texting unique in people with multiple sclerosis? AB - The objective of the study was to investigate cognitive-motor interference of walking while texting in people with multiple sclerosis (PwMS). The study included 30 PwMS, mean disease duration 11.8 (SD = 6.8) years, and 15 healthy controls. The investigation included a cognitive assessment; texting assessment based on 100 typed characters; and gait assessment under two different conditions: normal walking and walking while texting. Outcome measures included the Symbol Digit Modalities Test to assess cognition. Texting measures included accuracy (%) and duration(s). Gait was assessed with axial accelerometers to quantify temporal measures. The dual-task cost percentage for the walking tests and texting accuracy was determined by calculating the percentage change from a single task to a double task. The impact of texting while walking on gait measures was significantly higher in PwMS; furthermore, texting was less accurate compared to the healthy controls. The dual-task cost for texting accuracy in the PwMS group was 153.3 (SD = 105.7) compared to 8.9 (SD = 26.6) in the healthy group. A significant association was found solely in the PwMS group between cognition and texting accuracy while in a sitting position (R2 = 0.564) and while walking (R2 = 0.534). The dual-task cost of walking and texting appears to be unique in the MS population. PMID- 30298277 TI - Vector competence analysis of two Aedes aegypti lineages from Bello, Colombia, reveals that they are affected similarly by dengue-2 virus infection. AB - Dengue is the second most prevalent vector-borne disease after malaria in Colombia. It is caused by dengue virus, an arbovirus that exhibits high epidemic power, which is evidenced by its occurrence in more than 80% of the country, largely because of the extensive dispersion of the mosquito vector Aedes aegypti. The existence of two lineages of Ae. aegypti has been proposed based on genetic differences at the mitochondrial level, and they have been reported to circulate in similar proportions in the municipality of Bello (Colombia). It has been suggested that the differentiation of these lineages could influence features such as vector competence (VC) and life table. With the aim of testing this hypothesis, female mosquitoes from both lineages collected from Bello were orally challenged with dengue virus serotype 2 (strain D2-HAN) to measure infection, dissemination, survival and fecundity. Analysis of VC showed an increase in viral titer over time; however, no significant differences were observed between the lineages. The survival rate was not different between the infected lineages, but comparing lineages, it was lower in infected mosquitoes, which may affect the intensity of transmission. Finally, we conclude that the genetic differentiation of Ae. aegypti into lineages did not confer differences in epidemiological status when the mosquitoes were infected with this D2 serotype strain. PMID- 30298278 TI - Pharmacological characterization of the LSD analog N-ethyl-N-cyclopropyl lysergamide (ECPLA). AB - RATIONALE: The lysergamide lysergic acid diethylamide (LSD) is a prototypical classical hallucinogen with remarkably high potency. LSD remains a popular recreational drug but is also becoming an important research tool for medical and neuroscience studies. Recently, several lysergamides that are close structural analogs of LSD have been sold as recreational drugs, which suggests that further studies are needed to explore the pharmacological properties of these compounds. OBJECTIVE: In this present investigation, another LSD congener, N-ethyl-N cyclopropyl lysergamide (ECPLA), which to date has not been marketed as a recreational substance, was evaluated for its pharmacological features relative to those previously reported for LSD. The experiments focused on interactions with the 5-HT2A receptor, which is responsible for mediating the psychedelic effects of LSD and other hallucinogens. METHODS: Competitive binding assays were performed to measure the affinity of ECPLA for 27 monoamine receptors. The ability of ECPLA to activate human 5-HT2 receptor subtypes was assessed using calcium mobilization assays. Head twitch response (HTR) studies were conducted in C57BL/6J mice to determine whether ECPLA activates 5-HT2A receptors in vivo. Two other N-alkyl substituted lysergamides, N-methyl-N-isopropyl lysergamide (MIPLA) and N-methyl-N-propyl lysergamide (LAMPA), were also tested in the HTR paradigm for comparative purposes. RESULTS: ECPLA has high affinity for most serotonin receptors, alpha2-adrenoceptors, and D2-like dopamine receptors. Additionally, ECPLA was found to be a potent, highly efficacious 5-HT2A agonist for Gq-mediated calcium flux. Treatment with ECPLA induced head twitches in mice with a median effective dose (ED50) of 317.2 nmol/kg (IP), which is ~ 40% of the potency observed previously for LSD. LAMPA (ED50 = 358.3 nmol/kg) was virtually equipotent with ECPLA in the HTR paradigm whereas MIPLA (ED50 = 421.7 nmol/kg) was slightly less potent than ECPLA. CONCLUSIONS: These findings demonstrate that the pharmacological properties of ECPLA, MIPLA, and LAMPA are reminiscent of LSD and other lysergamide hallucinogens. PMID- 30298279 TI - Ceritinib for Untreated Anaplastic Lymphoma Kinase-Positive Advanced Non-Small Cell Lung Cancer: An Evidence Review Group Evaluation of a NICE Single Technology Appraisal. AB - The National Institute for Health and Care Excellence (NICE) invited the company that manufactures ceritinib (Zykadia(r), Novartis) to submit evidence on the clinical and cost effectiveness of the drug, as a first-line treatment for adults with anaplastic lymphoma kinase (ALK)-positive (+) advanced non-small-cell lung cancer (NSCLC), as part of the Institute's single technology appraisal (STA) process. The CRD (Centre for Reviews and Dissemination) and CHE (Centre for Health Economics) Technology Assessment Group at the University of York was commissioned to act as the Evidence Review Group (ERG). This paper describes the Company's submission (CS), the ERG review and NICE's subsequent decisions. The evidence submitted in support of ceritinib, as the first-line treatment in ALK+ advanced NSCLC, was a phase III, international, multicentre, open-label randomised controlled trial (RCT) comparing ceritinib with pemetrexed/cisplatin plus pemetrexed maintenance therapy (chemotherapy [CT] group). The results indicated that ceritinib prolonged progression-free survival (PFS) compared with CT. The only comparator considered in the CS was crizotinib. The evidence selected in support of crizotinib was PROFILE 1014, an open-label RCT of crizotinib, compared with pemetrexed/cisplatin CT (without maintenance therapy), in previously untreated advanced or metastatic ALK+ NSCLC. The design and population of PROFILE 1014 was similar to that of ASCEND-4, though there were some differences between the trials. The Company considered it not possible to perform an 'anchor-based' analysis of first-line ceritinib and crizotinib, and presented a Matching-Adjusted Indirect Comparison (MAIC) of ceritinib and crizotinib using only the ALK inhibitor arm of ASCEND-4 and PROFILE 1014. The indirect comparison suggests that ceritinib may be more effective in prolonging PFS than crizotinib. The ERG agreed that an indirect comparison using only the ALK inhibitor arm of the trials was the only option available in the present assessment; however, a number of limitations and potential bias were identified in this analysis. The Company's model estimated that ceritinib was cost effective when compared with crizotinib. However, the ERG highlighted several concerns with the Company's analysis; the ERG's preferred base case estimated an incremental cost-effectiveness ratio of L69,255 per quality-adjusted life-year (no patient access scheme [PAS] included). The ERG considered the economic analysis to be sensitive to changes in assumption used, partly due to the due to the immaturity of the overall survival data from trials, which leads to uncertainty around the extrapolation used. The NICE Appraisal Committee concluded that ceritinib is recommended, within its marketing authorisation, as an option for untreated ALK+ advanced NSCLC in adults, if the Company provides it with the discount agreed in the PAS. PMID- 30298280 TI - The Monetary Value of Informal Care: Obtaining Pure Time Valuations Using a Discrete Choice Experiment. AB - BACKGROUND: Interventions in health care often not only have an effect on patients, but also on their informal caregivers. Caregiving can have a profound impact on the health and wellbeing of carers. Ignoring these spillovers in economic evaluations risks labelling interventions mistakenly as cost-effective, at the expense of informal caregivers. OBJECTIVE: This paper investigates willingness-to-accept (WTA) values for an hour of informal care, corrected for positive and negative impacts of informal care, to facilitate the inclusion of informal care hours on the cost side of economic evaluations without double counting spillover effects. METHODS: A discrete choice experiment (DCE) was conducted among a representative sample of the adult population in the Netherlands (n = 552) in September 2011. An experimental design minimizing the D error was used to construct choice sets with two unlabelled alternatives with the attributes 'hours caregiving', 'monetary compensation for caregiving' and seven impacts of caregiving. To operationalize the random utility model, we used a panel mixed multinomial logit (MMNL) parameter model. For calculation of WTA, we used both population-level parameters and individual-level parameters. RESULTS: The mean WTA for an additional hour of informal care, corrected for positive and negative impacts of informal care, was ?14.57. The signs of the coefficients were all in the expected directions. CONCLUSIONS: This study reports a preference based monetary value for informal care, corrected for other impacts. This valuation facilitates the inclusion of informal care hours on the cost side in economic evaluations without double-counting any spillover effects included on the effects side. PMID- 30298281 TI - Sustained Elevation of Postoperative Serum Level of Carbohydrate Antigen 19-9 is High-Risk Stigmata for Primary Hepatic Recurrence in Patients with Curatively Resected Pancreatic Adenocarcinoma. AB - BACKGROUND: Survival after surgery for pancreatic adenocarcinoma (PA) is poor and heterogeneous, even for curative (R0) resection. Serum carbohydrate antigen (CA) 19-9 levels are important prognostic markers for resected PA. However, sustained elevation of CA19-9 in association with the patterns of recurrence has been rarely investigated. METHODS: Patients who underwent R0 resection (n = 539) were grouped according to postoperative serum CA19-9 levels (Group E: sustained elevation; Group N: no elevation). Clinicopathological factors, patterns of recurrence, and survival were compared between the groups. RESULTS: Group E (n = 159) had significantly shorter median overall survival (17.1 vs. 35.4 months, p < 0.0001) than Group N (n = 380). Postoperative CA19-9 elevation was a significant independent predictor of poor survival in multivariate analysis (hazard ratio 1.98, p < 0.0001). The rate of hepatic recurrence in Group E was 2.6-fold higher than in Group N (45% vs. 17%, p < 0.0001). Postoperative CA19-9 elevation was a strongest independent predictor of primary hepatic recurrence (p < 0.0001) by a multiple regression model. Loco-regional, peritoneal, and other distant recurrence did not differ between the groups. The extent of preoperative CA19-9 elevation was correlated sustained elevation of CA19-9 after surgery (p < 0.0001) and primary hepatic recurrence (p = 0.0019). CONCLUSIONS: Sustained CA19-9 elevation was strong predictor of primary hepatic recurrence and short survival in cases of R0 resection for PA. PMID- 30298282 TI - Role of Palliative Resection in Patients with Incurable Advanced Gastric Cancer Who are Unfit for Chemotherapy. AB - BACKGROUND: The REGATTA trial showed that gastrectomy followed by chemotherapy for advanced gastric cancer with a single non-curable factor did not improve survival outcomes in comparison with chemotherapy alone. Chemotherapy is therefore the mainstay treatment for incurable gastric cancer. However, for patients who are unfit for chemotherapy, the role of palliative gastrectomy remains controversial. METHODS: We retrospectively identified 207 patients with in curable gastric cancer who underwent palliative gastrectomy or bypass surgery because of urgent symptoms who were treated from 2002 to 2014. Fifty-nine of these patients who did not receive chemotherapy following surgery were enrolled in the present study. The patients were divided into the palliative gastrectomy group (n = 40) and the bypass surgery group (n = 19). The survival outcomes of the two groups were compared. Independent prognostic factors were identified using multivariate analysis. RESULTS: The rate of patients who underwent gastrectomy was significantly higher among patients whose tumors were located in the upper third (n = 19/20, 95%) than in patients whose tumors were located in the lower or middle third (n = 21/39, 54%, p = 0.001). The median survival time (MST) in the gastrectomy group (145 days) was significantly longer than that in the bypass group (86 days) (p = 0.008). Bypass surgery was identified as an independent prognostic factor in the multivariate analysis (HR = 2.3; 95%CI = 1.3 4.2 p = 0.007). CONCLUSIONS: Palliative gastrectomy may improve survival in patients with incurable gastric cancer who show emergent symptoms and who are unfit for chemotherapy. PMID- 30298283 TI - Healthcare Leaders Develop Strategies for Expanding National Surgical, Obstetric, and Anaesthesia Plans in WHO AFRO and EMRO Regions. AB - BACKGROUND: Worldwide, five billion people lack access to safe, affordable surgical, obstetric, and anaesthesia (SOA) care when needed. In many countries, a growing commitment to SOA care is culminating in the development of national surgical, obstetric, and anaesthesia plans (NSOAPs) that are fully embedded in the National Health Strategic Plan. This manuscript highlights the content and outputs from a World Health Organization (WHO) lead workshop that supported country-led plans for improving SOA care as a component of health system strengthening. METHODS: In March 2018, a group of 79 high-level global SOA stakeholders from 25 countries in the WHO AFRO and EMRO regions gathered in Dubai to provide technical and strategic guidance for the creation and expansion of NSOAPs. RESULTS: Drawing on the experience and expertise of represented countries that are at different stages of the NSOAP process, topics covered included (1) the global burden of surgical, obstetric, and anaesthetic conditions; (2) the key principles and components of NSOAP development; (3) the critical evaluation and feasibility of different models of NSOAP implementation; and (4) innovative financing mechanisms to fund NSOAPs. CONCLUSIONS: Lessons learned include: (1) there is unmet need for the establishment of an NSOAP community in order to provide technical support, expertise, and mentorship at a regional level; (2) data should be used to inform future priorities, for monitoring and evaluation and to showcase advances in care following NSOAP implementation; and (3) SOA health system strengthening must be uniquely prioritized and not hidden within other health strategies. PMID- 30298284 TI - A Comparison Between Plastic and Metallic Biliary Stent Placement in Patients Receiving Preoperative Neoadjuvant Chemoradiotherapy for Resectable Pancreatic Cancer. AB - BACKGROUND: The optimal stent type in patients receiving preoperative neoadjuvant chemoradiotherapy (NACRT) is uncertain. The present study aimed to compare the clinical effectiveness of biliary metallic stent (MS) and plastic stent (PS) in patients undergoing preoperative NACRT for resectable pancreatic cancer. METHODS: This retrospective study included 43 patients who required either biliary MS or PS before initiating NACRT for resectable or borderline resectable pancreatic head cancer. Seventeen patients had MS (MS group), while 23 patients had PS (PS group). All patients received preoperative NACRT, including gemcitabine and concomitant three-dimensional radiation of 54 Gy, and underwent pancreatectomy. Stent patency, surgery postponement, postoperative outcomes, and cost effectiveness were compared between these groups. RESULTS: There were no significant differences in baseline demographic or tumor characteristics between the groups. Stent patency was significantly longer in the MS group than in the PS group (p = 0.042). There were no differences in time to surgery, intraoperative characteristics, surgical complications, margin positivity, and pathological response between the groups. Furthermore, the medical cost of maintenance of biliary drainage during NACRT was similar between the groups. CONCLUSIONS: MS placement compared to PS in patients receiving preoperative NACRT provided no significant benefits during the postoperative course of pancreatectomy. However, MS placement was associated with long stent patency while showing no economic disadvantage. Therefore, MS placement may be recommended in patients receiving preoperative NACRT for resectable pancreatic cancer. PMID- 30298285 TI - Survival effect of perioperative systemic chemotherapy on overall mortality in locally advanced and/or positive regional lymph node non-metastatic urothelial carcinoma of the upper urinary tract. AB - OBJECTIVES: To analyze the potential survival benefit of perioperative chemotherapy (CHT) in patients treated with nephroureterectomy (NU) for non metastatic locally advanced upper tract urothelial carcinoma. METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2014), we identified 1286 patients with T3 or T4, N 0-3 M0 UTUC. Kaplan-Meier plots, as well as multivariable Cox regression models (MCRMs) relying on inverse probability after treatment weighting (IPTW) and landmark analyses, were used to test the effect of CHT vs no CHT on overall mortality (OM) in the overall population (n =1286), as well as after stratification according to lymph node invasion (LNI). RESULTS: Overall, 37.4% patients received CHT. The CHT rate was higher with LNI (62.2% vs 35.2%, p < 0.001). In MCRMs, testing for OM in the overall population, CHT was associated with lower rates of OM (HR 0.71, CI 0.58-0.87; p = 0.001). Similarly, in MCRMs testing for OM in patients with LNI, CHT achieved independent predictor status for lower OM (HR 0.61, CI 0.48-0.78; p < 0.001). Conversely, in MCRMs testing for OM in patients without LNI, no CHT effect was recorded (HR 0.72, CI 0.52-1.01; p = 0.05). All results were confirmed after IPTW adjustment and in landmark analyses. CONCLUSIONS: Our results represent a contemporary North American report indicating lower OM after CHT for patients with locally advanced non-metastatic upper tract urothelial carcinoma, specifically in patients with T3 T4, N1-N3, M0 disease. Validation of the current and of the previous study is required within a randomized prospective design. PMID- 30298286 TI - Prevalence and surgical management of concurrent adult acquired buried penis and urethral stricture disease. AB - PURPOSE: To describe the prevalence and surgical management of coexistent adult acquired buried penis (AABP) and urethral stricture disease. AABP patients often have urinary dribbling with resultant chronic local moisture, infection, and inflammation that combine to cause urethral stricture disease. To date, no screening or surgical management algorithms have been described. METHODS: A multi institutional retrospective study was conducted of the surgical management strategies for patients with concurrent AABP and urethral stricture disease from 2010 to 2017. AABP patient demographics, physical exam findings, and comorbidities were compared between those with and without stricture disease to suggest those that would selectively benefit from screening for stricture disease. RESULTS: Of the 42 patients surgically managed for AABP, 13 had urethral stricture disease (31.0%). Stricture location was universal in the anterior urethra. Sixty-one percent (n = 8) of strictures were 6 cm or longer and managed prior to AABP repair with Kulkarni urethroplasty. Patients with urethral stricture disease were significantly more likely to have clinically diagnosed lichen sclerosus (p = 0.00019). There was no significant difference in BMI, age, or comorbidities between patients with and without urethral stricture disease. CONCLUSIONS: Extensive anterior urethral stricture is common in patients with AABP. Clinical characteristics cannot predict stricture presence except possibly the presence of lichen sclerosus. Definitive stricture surgical options include extensive Johanson Urethroplasty or Kulkarni Urethroplasty. Kulkarni Urethroplasty prior to AABP repair has the benefits of a single-stage repair, good cosmetic outcome with meatal voiding, and dorsal graft placement to allow safe degloving of the penis in the subsequent AABP repair. PMID- 30298287 TI - The effect of short-term preoperative ureteral stenting on the outcomes of retrograde intrarenal surgery for renal stones. AB - OBJECTIVES: To evaluate the effect of preoperative ureteral stenting duration on the outcomes of retrograde intrarenal surgery (RIRS). PATIENTS AND METHODS: We reviewed our database of patients who underwent RIRS between May 2011 and April 2017 at our institution. The patients were divided into three groups according to preoperative ureteral stenting duration: group 1: no stenting, group 2: short preoperative stenting (< 7 days) and group 3: long preoperative stenting (>= 7 days). We compared the rate of ureteral injury, other perioperative complications, ureteral dilation and readmission, stone-free rate (SFR) and operative time among the groups. RESULTS: A total of 560 patients (215 in group 1, 177 in group 2 and 168 in group 3) were included in this study. The mean of maximum stone size was 13.1 (+/- 6.2) mm, the mean number of stones was 2.3 (+/- 1.9) and preoperative ureteral stenting duration was 7.2 (+/- 3.7) days. There were no significant differences in operative time (75.6, 78.5 and 82.4 min, p = 0.280), SFR (79.1, 84.2 and 81.0%, p = 0.433), ureteral injury rate (7.0, 5.1 and 2.4%, p = 0.123) and other perioperative complication rates (12.1, 6.8 and 6.0%, p = 0.061). The only one case of grade IV ureteral injury occurred in group 1 and the rate of ureteral dilation was significantly higher than in group 2 and 3 (14.9, 5.7 and 6.0%, p < 0.001). CONCLUSION: Although preoperative ureteral stenting duration has no significant effect on operative outcomes, it is an effective procedure for reducing the rate of intraoperative ureteral balloon dilation and preventing high-grade ureteral injuries. PMID- 30298288 TI - A systematic review on global pollution status of particulate matter-associated potential toxic elements and health perspectives in urban environment. AB - Airborne particulate matter (PM) that is a heterogeneous mixture of particles with a variety of chemical components and physical features acts as a potential risk to human health. The ability to pose health risk depends upon the size, concentration and chemical composition of the suspended particles. Potential toxic elements (PTEs) associated with PM have multiple sources of origin, and each source has the ability to generate multiple particulate PTEs. In urban areas, automobile, industrial emissions, construction and demolition activities are the major anthropogenic sources of pollution. Fine particles associated with PTEs have the ability to penetrate deep into respiratory system resulting in an increasing range of adverse health effects, at ever-lower concentrations. In depth investigation of PTEs content and mode of occurrence in PM is important from both environmental and pathological point of view. Considering this air pollution risk, several studies had addressed the issues related to these pollutants in road and street dust, indicating high pollution level than the air quality guidelines. Observed from the literature, particulate PTEs pollution can lead to respiratory symptoms, cardiovascular problems, lungs cancer, reduced lungs function, asthma and severe case mortality. Due to the important role of PM and associated PTEs, detailed knowledge of their impacts on human health is of key importance. PMID- 30298289 TI - Red bone marrow dose estimation using several internal dosimetry models for prospective dosimetry-oriented radioiodine therapy. AB - The aim of the present study was to review the available models developed for calculating red bone marrow dose in radioiodine therapy using clinical data. The study includes 18 patients (12 females and six males) with metastatic differentiated thyroid cancer. Radioiodine tracer of 73 +/- 16 MBq 131I was orally administered, followed by blood sampling (2 ml) and whole-body scans (WBSs) done at several time points (2, 6, 24, 48, 72, and >= 96 h). Red bone marrow dose was estimated using the OLINDA/EXM 1.0, IDAC-Dose 2.1, and EANM models, the models developed by Shen and co-workers, Keizer and co-workers and Siegel and co-workers, and Traino and co-workers, as well as the single measurement model (SMM). The results were then compared to the standard reference model Revised Sgouros Model (RSM) reported by Wessels and co-workers. The mean dose deviations of the Traino, Siegel, Shen, Keizer, OLINDA/EXM, EANM, SMM, and IDAC-Dose 2.1 models from the RSM were - 17%, - 24%, 6%, - 29%, - 15%, 40%, 48%, and - 8%, respectively. The statistical analysis demonstrated no significant difference between the results obtained with the RSM and with those obtained with the Shen, Traino, OLINDA/EXM, and IDAC-Dose 2.1 models (t test; pvalue > 0.05). However, a significant difference was found between RSM doses and those obtained with the EANM, SMM, and Keizer models (t test; pvalue < 0.05). The correlation between red marrow dose from the SMM and EANM models was modest (R2 = 0.65), while the crossfire dose calculated with the OLINDA/EXM and IDAC-Dose 2.1 models were in good agreement with each other and with the reference model. The findings obtained indicate that most of the dosimetry models can be used for a reliable dosimetry, and the calculated total body doses can be considered as a reliable non-invasive option for a conservative activity planning. In addition, the excellent performance of the IDAC-Dose 2.1 model will be of particular importance for a practical and accurate dosimetry, with the advantages of allowing for the use of realistic advanced phantoms and updated dose fractions, and of providing information about the blood dose contribution to the red bone marrow. PMID- 30298290 TI - Disinhibition of the prefrontal cortex leads to brain-wide increases in neuronal activation that are modified by spatial learning. AB - Deficient prefrontal cortex (PFC) GABA function is hypothesized to play a role in schizophrenia and other psychiatric disorders. In rodents, PFC GABAA receptor antagonism produces cognitive and behavioral changes relevant to these disorders, including impaired spatial memory assessed with the traditional working/reference memory radial maze task. This aspect of spatial memory does not depend on PFC, suggesting that deficient PFC GABAergic transmission may interfere with non-PFC dependent cognitive functions via aberrant increases in PFC output. To test this, we assessed whether PFC GABAA antagonism (50 ng bicuculline methbromide) alters neuronal activation in PFC terminal regions, including the striatum, thalamus, hippocampus, amygdala, and cortical regions, of adult male rats using the immediate early gene, c-Fos, as an activity marker. A subset of these animals were also trained and/or tested on the working/reference memory radial maze task. These treatments caused widespread increases in neuronal activation in animals under baseline conditions, with notable exception of the hippocampus. Furthermore, PFC GABAA antagonism impaired task performance. In most instances, training and/or testing on the radial maze had no additional effects on neuronal activation. However, in both the hippocampus and rhomboid thalamic nucleus, PFC GABAA antagonism caused a selective increase in neuronal activation in animals trained on the maze. These results indicate that deficiencies in PFC GABAergic transmission may have widespread impacts on neuronal activity that may interfere with certain PFC-independent cognitive functions. Furthermore, these alterations in activity are modulated by plasticity induced by spatial learning in the hippocampus and rhomboid thalamic nucleus.

AB - Neurobiological models have provided consistent evidence of the involvement of cortical-subcortical circuitry in obsessive-compulsive disorder (OCD). The orbitofrontal cortex (OFC), involved in motivation and emotional responses, is an important regulatory node within this circuitry. However, OFC abnormalities at the cellular level have so far not been studied. To address this question, we have recruited a total of seven senior individuals from the Sao Paulo Autopsy Services who were diagnosed with OCD after an extensive post-mortem clinical evaluation with their next of kin. Patients with cognitive impairment were excluded. The OCD cases were age- and sex-matched with 7 control cases and a total of 14 formalin-fixed, serially cut, and gallocyanin-stained hemispheres (7 subjects with OCD and 7 controls) were analyzed stereologically. We estimated laminar neuronal density, volume of the anteromedial (AM), medial orbitofrontal (MO), and anterolateral (AL) areas of the OFC. We found statistically significant layer- and region-specific lower neuron densities in our OCD cases that added to a deficit of 25% in AM and AL and to a deficit of 21% in MO, respectively. The volumes of the OFC areas were similar between the OCD and control groups. These results provide evidence of complex layer and region-specific neuronal deficits/loss in old OCD cases which could have a considerable impact on information processing within orbitofrontal regions and with afferent and efferent targets.

AB - INTRODUCTION: The objective of this video is to highlight strategies to improve operating room (OR) ergonomics, which will result in increased surgeon comfort during minimally invasive gynecologic surgery and decreased risk of musculoskeletal injury. METHODS: Work-related musculoskeletal disorders (WMSDs) are prevalent among surgeons, including those who perform minimally invasive gynecologic surgery. WMSDs are repetitive strain injuries that can damage a surgeon's muscles, nerves, and/or joints and commonly affect the neck, back, wrist, and hands. In addition to chronic pain, these injuries can lead to decreased job satisfaction and productivity. RESULTS: This video will discuss general ergonomic principles and demonstrate ergonomic techniques in conventional laparoscopic, vaginal, and robotic surgery. CONCLUSIONS: Minimally invasive gynecologic surgery can be physically taxing on the surgeon. Understanding principles and utilizing techniques of OR ergonomics can minimize these physical demands and result in a long, healthy, and pain-free surgical career. PMID- 30298295 TI - Investigation of eye movement pattern parameters of individuals with different fluid intelligence. AB - Eye movement studies are subject of interest in human cognition. Cortical activity and cognitive load impress eye movement influentially. Here, we investigated whether fluid intelligence (FI) has any effect on eye movement pattern in a comparative visual search (CVS) task. FI of individuals was measured using the Cattell test, and participants were divided into three groups: low FI, middle FI, and high FI. Eye movements of individuals were then recorded during the CVS task. Eye movement patterns were extracted and compared statistically among the three groups. Our experiment demonstrated that eye movement patterns were significantly different among the three groups. Pearson correlation coefficients between FI and eye movement parameters were also calculated to assess which of the eye movement parameters were most affected by FI. Our findings illustrate that saccade peak velocity had the greatest positive correlation with FI score and the ratio of total fixation duration to total saccade duration had the greatest negative correlation with FI. Next, we extracted 24 features from eye movement patterns and designed: (1) a classifier to categorize individuals and (2) a regression analysis to predict the FI score of individuals. In the best case examined, the classifier categorized subjects with 68.3% accuracy, and the regression predicted FI of individuals with a 0.54 correlation between observed FI and predicted FI. In our investigation, the results have emphasized that imposed loads on low FI individuals is greater than that of high FI individuals in the cognitive load tasks. PMID- 30298293 TI - Correlations between executive functions and adaptation to incrementally increasing sensorimotor discordances. AB - A previous study reported that movement directions adapt much better to 60 degrees target displacements (double steps) when target displacements are introduced incrementally and not abruptly. The present study tested whether incremental adaptation to 60 degrees discordances can be explained by specific cognitive abilities. The results showed that an increase of discordance size during adaptation enhanced reaction times. Furthermore, the individual performance in neuropsychological tests measuring sustained attention, figural fluency and perseveration predicted the rate of adaptation at different discordance sizes. These results are discussed with reference to recent models on directional selectivity and modularity during visually guided reaching. PMID- 30298294 TI - Individual preferences in motor coordination seen across the two hands: relations to movement stability and optimality. AB - The framework of the uncontrolled manifold (UCM) hypothesis was used to explore variables related to stability of task performance in the two hands of young healthy individuals. Fourteen young adults performed four-finger accurate constant force production tasks interrupted by a voluntary quick force pulse production and by an externally imposed displacement of all fingers. Three groups of variables were used to quantify stability of steady force production: (1) indices of the inter-trial variance were computed within the UCM and orthogonal to the UCM; (2) indices of motor equivalence were computed between steady-state intervals separated by the force pulse and by the finger-lifting episode; and (3) referent coordinate and apparent stiffness were computed using the data during the ascending phase of the finger-lifting episode. In another task, the subjects performed accurate constant force production with visual feedback removal after the 8th second, and the drop in the total force after the removal was computed. There were differences between the right and left hand in some outcome variables such as variance within the UCM, and the timing of anticipatory synergy adjustments prior to the force pulse, consistent with the dynamic dominance hypothesis. There were significant correlations between the two hands for indices that were unrelated to accuracy of performance: variance within the UCM, index of motor equivalence, referent coordinate, apparent stiffness, and the drop of total force after visual feedback removal. We interpret these findings within the concept of stability-optimality trade-off. In particular, we conclude that individual subjects select particular, person-specific solutions within the spectrum allowed by the explicit task constraints, and this choice is consistent between the two hands. We conclude with a hypothesis that selecting specific solutions within the stability-optimality trade-off may represent an individual's personal preference consistent between the two hands. PMID- 30298296 TI - Effect of the selective 5-HT2A receptor antagonist EMD-281,014 on L-DOPA-induced abnormal involuntary movements in the 6-OHDA-lesioned rat. AB - L-3,4-Dihydroxyphenylalanine (L-DOPA) is the most effective therapy for motor symptoms of Parkinson's disease (PD); however, with repeated administration, as many as 94% of PD patients develop complications such as L-DOPA-induced dyskinesia. We previously demonstrated that EMD-281,014, a highly selective serotonin 2A (5-HT2A) receptor antagonist, reduces the severity of dyskinesia in the parkinsonian marmoset, without interfering with L-DOPA anti-parkinsonian benefit. Here, we assessed the effects of EMD-281,014 on L-DOPA-induced abnormal involuntary movements (AIMs) in the 6-hydroxydopamine (6-OHDA)-lesioned rat. We first determined the pharmacokinetic profile of EMD-281,014, to administer doses leading to clinically relevant plasma levels in the behavioural experiments. Dyskinetic 6-OHDA-lesioned rats were then administered EMD-281,014 (0.01, 0.03 and 0.1 mg/kg) or vehicle in combination with L-DOPA and AIMs severity was evaluated. We also assessed the effect of EMD-281,014 on L-DOPA anti-parkinsonian action with the cylinder test. We found that the addition of EMD-281,014 (0.01, 0.03 and 0.1 mg/kg) to L-DOPA did not reduce AIMs severity (P > 0.05), when compared to vehicle. EMD-281,014 did not compromise L-DOPA anti-parkinsonian action. Our results suggest that the highly selective 5-HT2A receptor antagonist EMD-281,014 is well-tolerated by parkinsonian rats, but does not attenuate L-DOPA induced AIMs. Our results highlight differences between rodent and primate models of PD when it comes to determining the anti-dyskinetic action of 5-HT2A receptor antagonists. PMID- 30298297 TI - Knockdown of miR-372 Inhibits Nerve Cell Apoptosis Induced by Spinal Cord Ischemia/Reperfusion Injury via Enhancing Autophagy by Up-regulating Beclin-1. AB - To investigate the role of miR-372/Beclin-1 on nerve cell apoptosis induced by spinal cord ischemia/reperfusion injury (SCII). We established in vivo and in vitro SCII model. MiR-372 and Beclin-1 expressions in spinal cord tissues of SCII rats and SCII nerve cells were measured. The cell apoptosis was detected by flow cytometry. MiR-372 inhibitor was used to reduce miR-372 expression. Dual luciferase reporter assay was used to confirm the interaction between miR-372 and Beclin-1. MiR-372 expression in spinal cord tissues of SCII rats and SCII nerve cells was increased, while Beclin-1 expression was decreased. Knockdown of miR 372 could inhibit SCII nerve cell apoptosis. In addition, MiR-372 could negatively regulate Beclin-1 expression. Autophagy inhibitor could inhibit autophagy to promote the apoptosis of SCII nerve cells through decreasing Beclin 1, while interference of miR-372 changed the effect of autophagy inhibitor. Interference of miR-372 could reduce nerve cell apoptosis in SCII via increasing autophagy by up-regulating Beclin-1. PMID- 30298298 TI - Serum Oxidative Stress Marker Levels in Unmedicated and Medicated Patients with Schizophrenia. AB - Oxidative stress has been suggested to be involved in schizophrenia, but studies have demonstrated inconsistent results on oxidative stress marker level/activity in patients with schizophrenia. In order to clarify the circulating oxidative stress marker level/activity in patients with schizophrenia, this study recruited 80 schizophrenia patients (40 first-episode, drug-free and 40 chronically medicated patients) and 80 controls to analyze serum activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and total antioxidant capacity (T-AOC), and levels of lipid peroxidation marker malondialdehyde (MDA) in schizophrenia patients, and whether they associate with the severity of the disease. We showed that only serum GSH-Px activity was significantly reduced in unmedicated patients with schizophrenia when compared with control subjects, whereas the other three analyzed oxidative stress markers did not show significant differences between cases and controls. Moreover, our results demonstrated that chronic medication increased GSH-Px activity and MDA levels in patients with schizophrenia, but reduced SOD activity in the patients. We also found that short-term antipsychotic treatments on the patients with schizophrenia reduced the SOD activity. Correlation analyses indicated that the oxidative stress marker activity/level is not significantly associated with the severity of schizophrenia, except that SOD level correlated with PANSS positive score significantly. Taken together, the data from the present study suggested that the dysfunctions of oxidative stress markers in patients with schizophrenia were mainly caused by antipsychotics, emphasizing increased oxidative stress as a potential side effect of antipsychotics on the patients. PMID- 30298299 TI - Versican silencing in BeWo cells and its implication in gestational trophoblastic diseases. AB - Versican is a proteoglycan known to interact with cells to influence their ability to proliferate, differentiate, migrate, invade and assemble extracellular matrix, with all of these cell functions present during placentation. In the placenta, cytotrophoblast cells have the ability to differentiate into the syncytiotrophoblast, a mechanism that is greatly increased in gestational trophoblastic diseases (GTD). Nevertheless, the molecular signaling underlying the increased syncytiotrophoblast differentiation are still being unveiled and may result in novel therapeutic targets for GTD. Versican expression was investigated to establish its differential expression among GTD (partial moles, complete moles, invasive moles and choriocarcinoma) and the possible functional outcomes from versican gene silencing. Tissue samples had their versican expression evaluated using immunohistochemistry and RT-PCR. BeWo cells were employed for versican silencing with siRNA and the efficiency was confirmed by RT PCR, immunofluorescence and flow cytometry. Cell death and forskolin-induced syncytialization were analyzed by a morphological analysis and human chorionic gonadotropin (hCG) production using immunofluorescence. Versican V0 and V1 isoforms were mainly expressed in the syncytiotrophoblast and they were the most expressed in benign rather than in malignant tumors. BeWo cells also expressed V0 and V1 isoforms, but only in cells undergoing syncytial fusion. After versican silencing, cell death was greatly increased, whereas spontaneous and forskolin induced syncytialization decreased as well as hCG production. Versican is differentially expressed in GTD and is important for hydatidiform moles pathophysiology, protecting trophoblast cells from death and playing a role in their differentiation and functionality. PMID- 30298300 TI - Low-power laser alters mRNA levels from DNA repair genes in acute lung injury induced by sepsis in Wistar rats. AB - Acute lung injury (ALI) is defined as respiratory failure syndrome, in which the pathogenesis could occur from sepsis making it a life-threatening disease by uncontrolled hyperinflammatory responses. A possible treatment for ALI is the use of low-power infrared lasers (LPIL), whose therapeutical effects depend on wavelength, power, fluence, and emission mode. The evaluation mRNA levels of repair gene related to oxidative damage after exposure to LPIL could provide important information about the modulation of genes as treatment for ALI. Thus, the aim of this study was to evaluate the mRNA levels from OGG1, APEX1, ERCC2, and ERCC1 genes in lung tissue from Wistar rats affected by ALI and after exposure to LPIL (808 nm; 100 mW). Adult male Wistar rats (n = 30) were randomized into six groups (n = 5, for each group): control, 10 J/cm2 (2 J), 20 J/cm2 (5 J), ALI, ALI + LPIL 10 J/cm2 and ALI + LPIL 20 J/cm2. ALI was induced by intraperitoneal E. coli lipopolysaccharide injection (10 mg/kg). Lungs were removed, and samples were withdrawn for total RNA extraction, cDNA synthesis, and mRNA levels were evaluated by RT-qPCR. Data normality was verified by Kolmogorov Smirnov, comparisons among groups were by Student's t test, Mann-Whitney test, one-way ANOVA, Kruskal-Wallis followed by post-tests. Data showed that OGG1 (0.39 +/- 0.10), ERCC2 (0.67 +/- 0.24), and ERCC1 (0.60 +/- 0.19) mRNA levels are reduced in ALI group when compared with the control group (1.00 +/- 0.07, 1.03 +/ 0.25, 1.01 +/- 0.16, respectively) and, after LPIL, mRNA relative levels from DNA repair genes are altered when compared to non-exposed ALI group. Our research shows that ALI alter mRNA levels from genes related to base and nucleotide excision repair genes, suggesting that DNA repair is part of cell response to sepsis, and that photobiomodulation could modulate the mRNA levels from these genes in lung tissue.

PMID- 30298302 TI - Safety and efficacy of immune checkpoint inhibitors for end-stage renal disease patients undergoing dialysis: a retrospective case series and literature review. AB - Despite the lack of safety and efficacy data regarding immune checkpoint inhibitors (ICIs) for renal dysfunction, they have been approved to treat even in the patients with end-stage renal disease (ESRD). We report our experience with ICI administration to three ESRD patients undergoing hemodialysis. One of the patients had a partial response for several months; however, the other patients had a stable disease while undergoing dialysis. The toxicity was tolerable; however, one patient developed grade 2 pneumonitis. A literature review of other rarely reported cases of hemodialysis revealed that 10 out of 13 patients had a partial response or complete response; in addition, grade 3 or grade 4 immune related adverse events occurred in 3 patients. ESRD combined with dialysis may not be a contraindication for the use of ICIs. ICIs can be beneficial to ESRD patients undergoing dialysis. However, caution is needed regarding immune-related adverse events. Further prospective studies involving pharmacokinetic analyses are necessary to obtain reliable safety and efficacy data. PMID- 30298303 TI - Phase 1 trial of enzalutamide in combination with gemcitabine and nab-paclitaxel for the treatment of advanced pancreatic cancer. AB - Background Androgens were shown to play a key role in the growth and progression of pancreatic cancer. We evaluated the safety and tolerability of the combination of enzalutamide, a novel androgen receptor (AR) antagonist with gemcitabine and nab-paclitaxel as a first-line treatment in advanced pancreatic cancer. Methods We used the standard 3 + 3 dose escalation design with cohort expansion to evaluate 2 dose levels of enzalutamide: 80 mg and 160 mg/day orally (phase 1a) in combination with gemcitabine and nab-paclitaxel in metastatic pancreatic cancer patients. In the expansion phase (phase 1b), AR+ was a pre-requisite criterion. We also evaluated the full pharmacokinetic (PK) profile for nab-paclitaxel and enzalutamide. Results We enrolled 24 patients, 12 patients in phase 1a and 12 patients in phase 1b. The median age was 68 (range, 32-84) years. No DLTs were observed. Grade 3/4 treatment related adverse events included neutropenia (44%), anemia (40%), leukopenia (24%), nausea and vomiting (20%), diarrhea (16%), infections (12%), thrombocytopenia (8%), thromboembolic event (8%), hypertension (8%), hypokalemia (8%), hyponatremia (8%), and ALT elevation (8%). Median overall survival and progression-free survival was 9.73 [95%CI:9.73-13.5] and 7.53 (95%CI:6.05-12.8) months, respectively. PK analysis suggests that the combination therapy does not impact the kinetics of either drug evaluated. Enzalutamide reached steady-state levels between day 22 and 29 and the mean half-life of nab paclitaxel was 19.6 +/- 4.7 h. Conclusions Enzalutamide 160 mg daily in combination with gemcitabine and nab-paclitaxel can be safely administered with no unexpected toxicities. We also noticed preliminary signals of efficacy with this combination. PMID- 30298304 TI - Effect of a new inhibitor of factor Xa zifaxaban, on thrombosis in the inferior vena cava in rabbits. AB - In recent years, oral factor Xa inhibitors have become a research focus as anticoagulant drugs. Zifaxaban is the first oral FXa inhibitor to enter clinical trials in China. The aim of this study was to determine the inhibitory effect of zifaxaban on thrombosisthrough a model ofinferior vena cava (IVC) thrombosis in rabbits. IVC thrombosis model was established by electrical injury and stenosis, and zifaxaban was administered (p.o.) for 5 consecutive days, then coagulation indicators and bleeding were observed. The results showed that zifaxaban had obvious inhibitory effects on FXa, and had a significant inhibitory effect on IVC thrombosis induced by electrical damage and stenosis. The effect of zifaxaban was similar to that of rivaroxaban, but the bleeding side-effects of zifaxaban were less severe than those of rivaroxaban. Zifaxaban could prolong the prothrombin time and activated partial thromboplastin time of plasma similar to that of other oral FXa inhibitors. Zifaxaban had a significant inhibitory effect on FXa, but it had no obvious effect on other coagulation factors, major anticoagulant factors or fibrinolytic indices. Our results suggest that zifaxaban had specific inhibitory effects on FXa and inhibited IVC thrombosis in rabbits with its hemorrhagic effect was less than that of rivaroxaban. Zifaxaban is ecpected to be developed as a new drug for the prevention of deep venous thrombosis, providing more medication options for patients with such disease, more research is required to support it in the future. PMID- 30298305 TI - Direct oral anticoagulants: a review of common medication errors. AB - Stroke and venous thromboembolism continues to be a major cause of morbidity and mortality worldwide. The use of anticoagulation therapy has proven effective in the prevention of stroke and management of thromboembolism; however, initiating treatment may bear clinical burden given the capacity of these agents to cause bleeding. Originally, warfarin has been primarily used, but with the approval of direct oral anticoagulants, therapeutic recommendations have shifted to direct oral anticoagulants for first line therapy for venous thromboembolism for patients without cancer. As compared to warfarin, direct oral anticoagulants are associated with predictable pharmacokinetic profiles, lower bleeding risks, and minimal drug interactions. Complexities in the medication use process can however heighten the risks of causing adverse events. The purpose of this article is to describe common medication errors associated with direct oral anticoagulants, provide practical guidance on the management of direct oral anticoagulants, and suggest strategies to reduce errors. Efforts to minimize medication errors involve the participation of an interdisciplinary team that has standardized policies, risk reduction strategies, and guiding principles to achieve optimal therapeutic outcomes. Current primary literature is not robust in assessment of clinical impact of medication errors associated with DOACs but reports of adverse drug events have been noted. Future studies should be guided to assess clinical outcomes associated with medication errors and identify potential clinical interventions to optimize therapy.

PMID- 30298307 TI - The overexpression of cucumber (Cucumis sativus L.) genes that encode the branched-chain amino acid transferase modulate flowering time in Arabidopsis thaliana. AB - KEY MESSAGE: The overexpression of CsBCATs promotes flowering in Arabidopsis by regulating the expression of flowering time genes. The branched-chain amino acid transferases (BCATs) play an important role in the metabolism of branched-chain amino acids (BCAAs), such as isoleucine, leucine, and valine. They function in both the synthesis and the degradation of this class of amino acids. We identified and characterized the three BCAT genes in cucumber (Cucumis sativus L.). The tissue-specific expression profiling in cucumber plants revealed that CsBCAT2 and CsBCAT7 were highly expressed in the reproductive tissues, whereas CsBCAT3 expression was highly detected in the vegetative tissues. The subcellular localization patterns of three CsBCATs were observed in the mitochondria. The functional analyses of CsBCATs showed that CsBCAT2 and CsBCAT3 restored the growth of bat1Delta/bat2Delta double knockout yeast (Saccharomyces cerevisiae), and CsBCAT3 and CsBCAT7 with different substrate preferences acted in a reverse reaction. The transgenic approach demonstrated that the overexpression of the three CsBCATs resulted in early flowering phenotypes, which were associated with the upregulation of FLOWERING LOCUS T (FT) and SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (SOC1) in a manner in which they were dependent on GIGANTEA (GI)/CONSTANS (CO) and SHORT VEGETATIVE PHASE (SVP)/FLOWERING LOCUS C (FLC) modules. Our results, which are observed in conjunction, suggest that there is an interconnection between BCAT genes that function in BCAA metabolism and the flowering time in plants. PMID- 30298309 TI - Preventing Future Deaths from Medicines: Responses to Coroners' Concerns in England and Wales. AB - INTRODUCTION: Coroners inquire into sudden, unexpected, or unnatural deaths. We have previously established 99 cases (100 deaths) in England and Wales in which medicines or part of the medication process or both were mentioned in coroners' 'Regulation 28 Reports to Prevent Future Deaths' (coroners' reports). OBJECTIVE: We wished to see what responses were made by National Health Service (NHS) organizations and others to these 99 coroners' reports. METHODS: Where possible, we identified the party or parties to whom these reports were addressed (names were occasionally redacted). We then sought responses, either from the UK judiciary website or by making requests to the addressee directly or, for NHS and government entities, under the Freedom of Information Act 2000. Responses were analysed by theme to indicate the steps taken to prevent future deaths. RESULTS: We were able to analyse one or more responses to 69/99 cases from 106 organizations. We analysed 201 separate actions proposed or taken to address the 160 concerns expressed by coroners. Staff education or training was the most common form of action taken (44/201). Some organisations made changes in process (24/201) or policy (17/201), and some felt existing policies were sufficient to address some concerns (22/201). CONCLUSIONS: Coroners' concerns are often of national importance but are not currently shared nationally. Only a minority of responses to coroners' reports concerning medicines are in the public domain. Processes for auditing responses and assessing their effectiveness are opaque. Few of the responses appear to provide robust and generally applicable ways to prevent future deaths. PMID- 30298308 TI - Metagenomic analysis and the functional profiles of traditional fermented pork fat 'sa-um' of Northeast India. AB - Fermented pork fat (sa-um) is traditionally and extensively consumed in Northeast Indian region for several decades. However, no scientific reports are available regarding its nutritional value as well as its potential health risks. The objective of this work was essentially the characterization of sa-um using a polyphasic approach, viz., physicochemical, electrospray ionization-mass spectrometry (ESI+-MS) and metagenomic analysis in order to gain an understanding of the nutrient contents and microbial population diversity. On a dry weight basis, about 91% fat, 2% carbohydrate and 0.70% protein were present. ESI+-MS analysis of sa-um revealed the presence of various polar and neutral lipids corresponding to monoacylglyceride, diacylglyceride and triacylglyceride species. The dominant bacterial phyla were Firmicutes, Proteobacteria and Bacteroidetes. A total of 72 bacterial genera were identified, largely abundant with Clostridium species including C. butyricum, C. citroniae, C. methylpentosum, C. perfringens, C. saccharogumia and C. tetani. The imputed functional profiles of bacterial communities were predominantly involved in energy, carbohydrate and amino acid metabolisms. Furthermore, this study deduces the presence of pro-inflammatory molecules as well as antibiotic resistance genes associated with the bacterial families such as Bacillaceae, Bacteroidaceae, Clostridiaceae, Corynebacteriaceae and Enterobacteriaceae which might be a major health concern for the sa-um consuming population.

PMID- 30298311 TI - Multifocal/Multicentric Ipsilateral Invasive Breast Carcinomas with Similar Histology: Is Multigene Testing of All Individual Foci Necessary? AB - BACKGROUND: Multiple synchronous ipsilateral invasive breast carcinomas (BCs) with similar histology usually have concordant receptor status. It is unknown whether individual foci with similar histology also share molecular and biological similarities or are heterogenous. This study examined the concordance of the 21-gene recurrence score (RS) in multiple synchronous morphologically similar ipsilateral BCs. PATIENTS AND METHODS: We identified patients with multiple ipsilateral BCs and available RS treated at our institution from 1/2014 to 6/2018. BCs were divided into three groups based on RS: (1) RS in same risk category, (2) RS in different risk categories but within 2-unit difference (e.g., RS 17 and RS 19), and (3) RS in different risk categories and a change of > 2 units. BCs in groups 1 and 2 were considered as concordant (no significant clinical impact) and BCs in group 3 as discordant (variation affects management). RESULTS: A total of 53 patients met the study criteria. RS was concordant in 46 (87%) cases. Seven (13%) cases were discordant (group 3). Of these, three (43%, 3/7) had biopsy cavity changes (BXC) adjacent to the BC with highest RS. In two cases the focus with higher RS had a lower percentage of progesterone receptor positive tumor cells. In two cases, extensive ductal carcinoma in situ was associated with the BC focus with lower RS. CONCLUSIONS: Morphologically similar multifocal ipsilateral BCs have concordant RS in 87% (46/53) of cases. Our results suggest that, in cases of morphologically similar multifocal BCs, testing of a single focus provides accurate prognostic and predictive information.

PMID- 30298316 TI - Intraoperative Dexamethasone Decreases Infectious Complications After Pancreaticoduodenectomy and is Associated with Long-Term Survival in Pancreatic Cancer. AB - BACKGROUND: Dexamethasone is administered intraoperatively to prevent anesthesia related nausea and vomiting and to reduce postoperative opioid administration. However, the adverse effects of corticosteroids on anastomotic healing and wound infection as well as oncologic outcomes remain unclear. We analyzed the effect of intraoperative dexamethasone administration on surgical outcomes after pancreaticoduodenectomy and on long-term survival in pancreatic cancer patients. METHODS: A total of 679 pancreaticoduodenectomies from a prospectively maintained database were analyzed. Surgical outcomes were compared between patients who received intraoperative dexamethasone and those who did not. Kaplan-Meier curves and Cox-regression survival analysis were performed in patients with pancreatic cancer. A propensity analysis was done to reduce the inherent bias of retrospective design. RESULTS: Patients who received dexamethasone (117, 17.2%) were younger and more likely to be female than those who did not (p = 0.001). Overall and 30-day major morbidity were similar among all resected patients, although there were fewer infectious complications in the dexamethasone group (18.8% vs. 28.5%, p = 0.032). In pancreatic cancer patients, dexamethasone was associated with significantly improved median overall survival (46 vs. 22 months, p = 0.017). This effect occurred independently of stage, pathologic characteristics, or adjuvant therapy, with adjusted hazard ratios, derived from pre-propensity and post-propensity analysis, of 0.67 (0.47-0.97) and 0.57 (0.37 0.87), respectively. CONCLUSIONS: A single intraoperative dose of dexamethasone did not increase morbidity after pancreaticoduodenectomy and, in fact, was associated with a decrease in infectious complications. The treatment was independently associated with improved overall survival in patients with pancreatic adenocarcinoma, an effect that cannot be explained and needs further validation in a prospective setting.

AB - BACKGROUND: Talimogene laherparepvec (TVEC) is an oncolytic herpes virus used as intralesional therapy for patients with unresectable stage IIIB through IV melanoma. We reviewed the standard of care treatment of TVEC at a single institution. METHODS: All patients treated with TVEC for advanced melanoma were retrospectively evaluated from 2015 to 2018. Patient demographics, clinicopathologic characteristics, treatment response, and toxicity were reviewed. RESULTS: Twenty-seven patients underwent therapy with TVEC. Median age was 75 years, and 63% of patients were female. Seventeen (63.0%) patients underwent injections on the lower extremity, four (14.8%) on the upper extremity, four (14.8%) on the head and neck, and two (7.4%) on the trunk. Median number of injections was five. Median follow-up was 8.6 months. Of the 27 patients, 23 patients met the criteria for response analysis with at least 8 weeks follow-up. Ten (43.5%) patients experienced a complete response (CR), three (13.1%) experienced a partial response (PR), and five (21.7%) had stable disease (SD) for an overall response rate of 56.5% (CR + PR) and a disease control rate of 78.3% (CR + PR + SD). Adverse events were mostly limited to mild constitutional symptoms within 48 h of injection. Two patients developed cellulitis treated with oral antibiotics, and one patient underwent excision of a lesion for ulceration and bleeding during therapy. DISCUSSION: TVEC is an effective and well-tolerated intralesional therapy for patients with unresectable stage IIIB through IV melanoma. A CR was achieved in almost half of patients treated. Disease control is seen in the vast majority. PMID- 30298319 TI - ASO Author Reflections: Biological Diversity of Histologic Subtypes.

AB - BACKGROUND: The surgical care of patients with metastatic gastric cancer (GC) remains debated. Despite level 1 evidence showing lack of survival benefit, surgery may be used for symptoms prevention or palliation. This study examined short-term postoperative outcomes of non-curative gastrectomy performed for metastatic GC. METHODS: A multi-institutional retrospective cohort study was conducted using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) registry, including gastrectomies for GC (2007 2015). The primary outcome was 30-day major morbidity. Multivariable analysis examined the association between metastatic status and outcomes adjusted for relevant demographic and clinical covariates. RESULTS: Of 5341 patients, 377 (7.1%) had metastases. Major morbidity was more common with metastases (29.4 vs. 19.6%; p < 0.001), driven by a higher rate of respiratory events. Prolonged hospital length of stay (beyond the 75th percentile: 11 days) was more likely with metastases than with no metastases (41.9 vs. 28.3%; p < 0.001). After adjustment, metastatic status was associated with major morbidity (odds ratio [OR], 1.49; 95% confidence interval [CI], 1.16-1.90). This association remained for respiratory events (OR, 1.58; 95% CI, 1.07-2.33), 30-day mortality (OR, 2.19; 95% CI, 1.38-3.48), and prolonged hospital stay (OR, 1.65; 95% CI, 1.31-2.07). CONCLUSION: Non-curative gastrectomy for metastatic GC was associated with significant major morbidity and mortality as well as a prolonged hospital stay, longer than expected for gastrectomy for non-metastatic GC. These data can inform decision making regarding non-curative gastrectomy, helping surgeons to weigh the risks of morbidity against the potential benefits and alternative therapeutic options.

PMID- 30298320 TI - Influence of Age on the Clinical Outcome of Breast Cancer for Men and the Development of Second Primary Cancers. AB - BACKGROUND: Low incidence of breast cancer in men (BCM) (< 1% of all breast cancers) has led to a paucity of outcome data. This study evaluated the impact of age on BCM outcomes. METHODS: For this study, BCM patients treated between 2000 and 2011 were stratified by age (<= 65 or > 65 years). Kaplan-Meier methods were used to compare overall survival (OS) and breast cancer-specific survival (BCSS). Competing-risk methods analyzed time to second primary cancers (SPCs), with any cause death treated as a competing risk. RESULTS: The study identified 152 BCM patients with a median age of 64 years (range 19-96 years). The median body mass index (BMI) was 28 kg/m2. Men age 65 years or younger (n = 78, 51%) were more overweight/obese than men older than 65 years (n = 74, 49%) (89% vs 74%, respectively; P = 0.008). Both groups had similar nodal metastases rates (P = 0.4), estrogen receptor positivity (P = 1), and human epidermal growth factor receptor 2 (HER2)neu overexpression (P = 0.6). Men 65 years of age or younger were more likely to receive chemotherapy (P = 0.002). The median follow-up period was 5.8 years (range 0.1-14.4 years). The 5-year OS was 86% (95% confidence interval [CI] 80-93%), whereas the 5-year BCSS was 95% (95% CI 91-99%). The BCM patients 65 years of age and younger had better OS (P = 0.003) but not BCSS (P = 0.8). The 5-year cumulative incidence of SPC was 8.4% (95% CI 3.4-13.4%). The prior SPC rate was higher for men older than 65 years (n = 20, 31%) than for those age 65 years or younger (n = 7, 11%) (P = 0.008). This did not account for differences in life years at risk. No difference was observed in SPC cumulative incidence stratified by age (P = 0.3). CONCLUSIONS: Men 65 years of age or younger received more chemotherapy and had improved OS, but not BCSS, compared with men older than 65 years. For all BCM, SPC is a risk, and appropriate screening may be warranted.

PMID- 30298331 TI - Association Between Very Small Tumor Size and Decreased Overall Survival in Node Positive Pancreatic Cancer. AB - BACKGROUND: In pancreatic adenocarcinoma (PDAC), increasing tumor size usually correlates with a worse prognosis. However, patients with a very small primary tumor who experience lymph node involvement may have a different disease biology. This study sought to determine the interaction between tumor size and lymph node involvement in terms of overall survival (OS). METHODS: The study identified 17,073 patients with a diagnosis of M0 resected PDAC between 1983 and 2013 using the Surveillance, Epidemiology, and End Results database. The patients were stratified by lymph node involvement (N0 vs N+) and T stage (T1a-T1b vs T1c vs T2 vs T3 vs T4). The Kaplan-Meier method was used to estimate OS, and Cox regression analysis was used to compare survival between subgroups after adjustment for patient-specific factors. RESULTS: Lymph node involvement and T stage significantly interacted (p < 0.001). Among the patients with node-negative disease, 5-year OS decreased monotonically with increasing T stage (59.1%, 30.6%, 22.9%, 16.6%, and 8.0%, respectively; p < 0.001). In contrast, among the patients with node-positive disease, those with T1a-T1b tumors (< 10 mm) had worse 5-year OS than those with T1c tumors (7.4% vs 17.6%; adjusted hazard ratio, 0.70; 95% confidence interval, 0.50-0.97; p = 0.034) and similar survival compared with those who had T2, T3, or T4 tumors (9.7%, 8.2%, and 4.8%, respectively; p > 0.2 in all cases). CONCLUSIONS: Among patients with lymph node-positive PDAC, very small primary tumors are associated with decreased OS. This finding raises the possibility that small tumors capable of lymph node metastasis might represent more biologically aggressive cancers. PMID- 30298332 TI - Lifespan Development: Symptoms Experienced by Individuals with Neurofibromatosis Type 1 Associated Plexiform Neurofibromas from Childhood into Adulthood. AB - This secondary data analysis qualitatively identified salient concerns reported by individuals with Neurofibromatosis Type 1 (NF1)-associated plexiform neurofibromas (pNFs) at different stages of development. Past literature has focused on overall symptomatology, but has not examined nuances in how these symptoms are experienced across developmental phases. Therefore, we aimed to identify commonalities and differences in symptom experiences across age groups to better assist individuals to adjust to symptoms across the lifespan. Thirty one children, adolescents, and adults (age >= 5 years old) and 15 parents participated in semi-structured interviews. Analyses focused on the following symptom categories: pain, social functioning, physical function impact, and stigma. Aspects of pain endorsed by all age groups included localized brief pain on contact with pNF and abnormal sensations; however, only adolescents and adults reported chronic pain and change in pain over time. Social functioning themes of limited activity participation, role limitations, and relationship impact were endorsed by all age groups, but differences emerged across age groups in the types of activity and role limitations, the type of relationship impact, and family planning concerns. All age groups described difficulty with mobility, but only parents reported problems with coordination and physical developmental milestones. While all age groups reported external stigma, internalized stigma was predominately endorsed by adults. While individuals in all age groups described pNF concerns related to pain, social function, physical function, and stigma, specific aspects of these symptoms differed across the developmental continuum. These findings can help assist individuals with pNF better transition to the next developmental phases. PMID- 30298333 TI - [Digitalization and artificial intelligence in orthopedics and traumatology]. AB - In the course of digitalization it is becoming increasingly rare for medical documents to be handwritten. As a result, digitalization has already become an integral part of routine patient care but in contrast to other specialist disciplines, such as radiology or laboratory medicine, orthopedics and trauma surgery are still at the beginning of new technologies. Artificial intelligence is not only used in the form of surgical robots in joint surgery or in the design of individualized implants but also provides valuable decision-making aids through appropriate algorithms for diagnosis and treatment. It can be assumed that these technologies will be further developed and used increasingly more in the coming years. Typical examples are intuitively operable and autonomously working programs and systems that support the networking and work of medical personnel and make processes inside and outside inpatient care more precise and less vulnerable to disturbances.

PMID- 30298335 TI - The Timing of Tracheostomy and Outcomes After Aneurysmal Subarachnoid Hemorrhage: A Nationwide Inpatient Sample Analysis. AB - BACKGROUND: The goal of this study was to investigate the association of tracheostomy timing with outcomes after aneurysmal subarachnoid hemorrhage (SAH) in a national population. METHODS: Poor-grade aneurysmal SAH patients were extracted from the Nationwide Inpatient Sample (2002-2011). Multivariable linear regression was used to analyze predictors of tracheostomy timing and multivariable logistic regression was used to evaluate the association of timing of intervention with mortality, complications, and discharge to institutional care. Covariates included patient demographics, comorbidities, severity of subarachnoid hemorrhage (measured using the NIS-SAH severity scale), hospital characteristics, and other complications and length of stay. RESULTS: The median time to tracheostomy among 1380 poor-grade SAH admissions was 11 (interquartile range: 7-15) days after intubation. The mean number of days from intubation to tracheostomy in SAH patients at the hospital (p < 0.001) was the strongest predictor of tracheostomy timing for a patient, while comorbidities and SAH severity were not significant predictors. Mortality, neurologic complications, and discharge disposition did not differ significantly by tracheostomy time. However, later tracheostomy (when evaluated continuously) was associated with greater odds of pulmonary complications (p = 0.004), venous thromboembolism (p = 0.04), and pneumonia (p = 0.02), as well as a longer hospitalization (p < 0.001). Subgroup analysis only found these associations between tracheostomy timing and medical complications in patients with moderately poor grade (NIS-SAH severity scale 7-9), while there were no significant differences by timing of intervention in very poor-grade patients (NIS-SAH severity scale > 9). CONCLUSIONS: In this analysis of a large, national data set, variation in hospital practices was the strongest predictor of tracheostomy timing for an individual. In patients with moderately poor grade, later tracheostomy was independently associated with pulmonary complications, venous thromboembolism, pneumonia, and a longer hospitalization, but not with mortality, neurological complications, or discharge disposition. However, tracheostomy timing was not significantly associated with outcomes in very poor-grade patients. PMID- 30298336 TI - Effects of Osmotic Therapy on Pupil Reactivity: Quantification Using Pupillometry in Critically Ill Neurologic Patients. AB - BACKGROUND: Osmotic therapy is a critical component of medical management for cerebral edema. While up to 90% of neurointensivists report using these treatments, few quantitative clinical measurements guide optimal timing, dose, or administration frequency. Its use is frequently triggered by a qualitative assessment of neurologic deterioration and/or pupil size, and anecdotally appears to improve pupil asymmetry suggestive of uncal herniation. However, subjective pupil assessment has poor reliability, making it difficult to detect or track subtle changes. We hypothesized that osmotic therapy reproducibly improves quantitative pupil metrics. METHODS: We included patients at two centers who had recorded quantitative pupil measurements within 2 h before and after either 20% mannitol or 23.4% hypertonic saline in the neurosciences intensive care unit. The primary outcome was the Neurologic Pupil Index (NPi), a composite metric ranging from 0 to 5 in which > 3 is considered normal. Secondary outcomes included pupil size, percent change, constriction and dilation velocity, and latency. Results were analyzed with Wilcoxon signed-rank tests, Chi-square and multi-level linear regression to control for other edema-reducing interventions. RESULTS: Out of 72 admissions (403 paired pupil observations), NPi significantly differed within 2 h of osmotic therapy when controlling for other commonly used interventions in our whole cohort (beta = 0.08, p = 0.0168). The effect was most pronounced (beta = 0.57) in patients with abnormal NPi prior to intervention (p = 0.0235). CONCLUSIONS: Pupil reactivity significantly improves after osmotic therapy in a heterogenous critically ill population when controlling for various other interventions. Future work is necessary to determine dose-dependent effects and clinical utility. PMID- 30298338 TI - Abnormal Microvasculature in Laryngectomy Mucosal Margins may be Associated with Increased Risk of Fistula. AB - Pharyngocutaneous fistula after laryngectomy is common and significantly increases the morbidity of the procedure. Intraoperative, objective variables that can reliably predict fistula formation would be useful to surgeons deciding how to reconstruct the laryngectomy defect. Retrospective chart review of 50 radiated patients and 10 non-radiated patients who underwent total laryngectomy at a single tertiary care institution. Patients with pharyngocutaneous fistula were selected to ensure a representative sample were available for comparison. All patients had pathology slides available for re-review by a single, blinded pathologist. Margins of both radiated (n = 50) and non-radiated (n = 10) larynges were examined for 7 histologic features, and odds ratios were calculated to assess whether these features were associated with fistula. When evaluating all 60 patients, both telangiectatic capillaries and hyalinized arterioles were associated with fistula (OR 3.72 and 9.21, respectively). Collinearity between the variables was evaluated; findings indicated a high likelihood of having hyalinized arterioles if telangiectatic capillaries were also present (OR 31.67 [3.13, 320.06]). Microvascular changes in radiated tissue have previously been described in other anatomic subsites, but the larynx and pharynx have not been specifically evaluated. Laryngectomy mucosal margins appear to display similar changes, and evidence of this damage may be associated with fistula formation. These features could potentially guide the surgeon to alter the reconstructive technique. PMID- 30298337 TI - Medical Image Analysis using Convolutional Neural Networks: A Review. AB - The science of solving clinical problems by analyzing images generated in clinical practice is known as medical image analysis. The aim is to extract information in an affective and efficient manner for improved clinical diagnosis. The recent advances in the field of biomedical engineering have made medical image analysis one of the top research and development area. One of the reasons for this advancement is the application of machine learning techniques for the analysis of medical images. Deep learning is successfully used as a tool for machine learning, where a neural network is capable of automatically learning features. This is in contrast to those methods where traditionally hand crafted features are used. The selection and calculation of these features is a challenging task. Among deep learning techniques, deep convolutional networks are actively used for the purpose of medical image analysis. This includes application areas such as segmentation, abnormality detection, disease classification, computer aided diagnosis and retrieval. In this study, a comprehensive review of the current state-of-the-art in medical image analysis using deep convolutional networks is presented. The challenges and potential of these techniques are also highlighted. PMID- 30298339 TI - Mechanical Stretch of High Magnitude Provokes Axonal Injury, Elongation of Paranodal Junctions, and Signaling Alterations in Oligodendrocytes. AB - Increasing findings suggest that demyelination may play an important role in the pathophysiology of brain injury, but the exact mechanisms underlying such damage are not well known. Mechanical tensile strain of brain tissue occurs during traumatic brain injury. Several studies have investigated the cellular and molecular events following a static tensile strain of physiological magnitude on individual cells such as oligodendrocytes. However, the pathobiological impact of high-magnitude mechanical strain on oligodendrocytes and myelinated fibers remains under investigated. In this study, we reported that an applied mechanical tensile strain of 30% on mouse organotypic culture of cerebellar slices induced axonal injury and elongation of paranodal junctions, two hallmarks of brain trauma. It was also able to activate MAPK-ERK1/2 signaling, a stretch-induced responsive pathway. The same tensile strain applied to mouse oligodendrocytes in primary culture induced a profound damage to cell morphology, partial cell loss, and a decrease of myelin protein expression. The lower tensile strain of 20% also caused cell loss and the remaining oligodendrocytes appeared retracted with decreased myelin protein expression. Finally, high-magnitude tensile strain applied to 158N oligodendroglial cells altered myelin protein expression, dampened MAPK-ERK1/2 and MAPK-p38 signaling, and enhanced the production of reactive oxygen species. The latter was accompanied by increased protein oxidation and an alteration of anti-oxidant defense that was strain magnitude dependent. In conclusion, mechanical stretch of high magnitude provokes axonal injury with significant alterations in oligodendrocyte biology that could initiate demyelination. PMID- 30298340 TI - Immunosignature Analysis of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). AB - A random-sequence peptide microarray can interrogate serum antibodies in a broad, unbiased fashion to generate disease-specific immunosignatures. This approach has been applied to cancer detection, diagnosis of infections, and interrogation of vaccine response. We hypothesized that there is an immunosignature specific to ME/CFS and that this could aid in the diagnosis. We studied two subject groups meeting the Canadian Consensus Definition of ME/CFS. ME/CFS (n = 25) and matched control (n = 25) sera were obtained from a Canadian study. ME/CFS (n = 25) sera were obtained from phase 1/2 Norwegian trials (NCT01156909). Sera from six healthy controls from the USA were included in the analysis. Canadian cases and controls were tested for a disease immunosignature. By combining results from unsupervised and supervised analyses, a candidate immunosignature with 654 peptides was able to differentiate ME/CFS from controls. The immunosignature was tested and further refined using the Norwegian and USA samples. This resulted in a 256-peptide immunosignature with the ability to separate ME/CFS cases from controls in the international data sets. We were able to identify a 256-peptide signature that separates ME/CFS samples from healthy controls, suggesting that the hit-and-run hypothesis of immune dysfunction merits further investigation. By extending testing of both our signature and one previously reported in the literature to larger cohorts, and further interrogating the specific peptides we and others have identified, we may deepen our understanding of the origins of ME/CFS and work towards a clinically meaningful diagnostic biomarker. PMID- 30298341 TI - Driveline angle is crucial for preventing driveline infection in patients with HeartMate II device. AB - We hypothesized that the externalizing direction of the driveline (the driveline angle) at the percutaneous exit site would influence the occurrence of driveline infection after left ventricular assist device implantation. From August 2013 to May 2017, 71 patients were implanted with a HeartMate II device in our center. The driveline angle was measured on anteroposterior radiography just after implantation. Risk factors for driveline infection were analyzed by uni- and multivariate analyses. Driveline infection developed in 10 (14%) patients during follow-up. Overall actual freedoms from driveline infection at 6, 12, and 24 months were 96%, 88%, and 86%, respectively. Overall number of driveline infection events per patient-year was 0.16. Receiver operating characteristic analysis determined the cut-off point of the driveline angle as 41 degrees . The 6-, 12-, and 24-month actuarial freedoms from driveline infection in those with driveline angle more than 42 degrees (84%, 74%, and 74%, respectively) were significantly lower than in those with driveline angle less than 41 degrees (97%, 94%, and 90%, respectively; p < 0.02). The numbers of driveline infection events per patient-year were 0.16 in patients with driveline angle more than 42 degrees , and 0.04 in patients with driveline angle less than 41 degrees . Multivariate analysis demonstrated that driveline angle more than 42 degrees was an independent risk factor for driveline infection (hazard ratio 4.71). Driveline angle more than 42 degrees is an independent risk factor for driveline infection in patients with HeartMate II. Externalization of the driveline toward the horizontal direction is important to prevent driveline infection with HeartMate II. PMID- 30298342 TI - Iridescent colouration of male Anna's hummingbird (Calypte anna) caused by multilayered barbules. AB - The male Anna's hummingbird features a brightly reddish-pink reflecting gorget, due to large stacks of melanosomes in the feather barbules, arranged in layers separated by keratin. Direct observations together with detailed scatterometry demonstrated that the barbules reflect incident light in an approximately specular manner. The structural colouration is iridescent, i.e. varies with a changing angle of light incidence. Spectrophotometrical measurements of the barbule reflectance and absorbance can be well interpreted with calculated spectra obtained with a transfer matrix method for optical multilayers, using anatomical data and measured refractive index spectra. The organization of the reflectors as a Venetian blind presumably functions to create a high spectral contrast of the male's plumage during courtship. PMID- 30298343 TI - A simple mathematical model using centred loops and random perturbations accurately reconstructs search patterns observed in desert ants. AB - This paper describes a new mathematical model that is based on centred loops to reconstruct the "Systematic Search" behaviour of Cataglyphis desert ants. The notable advantage of this model is the combination of simplicity, efficiency and performance. All model input is kept to a minimum, using only parameters that previous research has shown to be available to the animals at all times: distance from the origin, direction of the last step and home vector. Outbound and inbound search paths are being combined into loops that return to the origin, sampling this area more intensely. A stochastic element is added by random perturbations during the next step, mimicking unsystematic errors during the process of path integration and yielding the typical search patterns observed in Cataglyphis desert ants. The model output is compared to runs observed in the field. PMID- 30298344 TI - Metal-Induced Pulmonary Fibrosis. AB - PURPOSE OF REVIEW: The incidence of pulmonary fibrosis is increasing worldwide and may, in part, be due to occupational and environmental exposures. Secondary fibrotic interstitial lung diseases may be mistaken for idiopathic pulmonary fibrosis with important implications for both disease management and prognosis. The purposes of this review are to shed light on possible underlying causes of interstitial pulmonary fibrosis and to encourage dialogue on the importance of acquiring a thorough patient history of occupational and environmental exposures. RECENT FINDINGS: A recent appreciation for various occupational and environmental metals inducing both antigen-specific immune reactions in the lung and nonspecific "innate" immune system responses has emerged and with it a growing awareness of the potential hazards to the lung caused by low-level metal exposures. Advancements in the contrast and quality of high-resolution CT scans and identification of histopathological patterns of interstitial pulmonary fibrosis have improved clinical diagnostics. Moreover, recent findings indicate specific hotspots of pulmonary fibrosis within the USA. Increased prevalence of lung disease in these areas appears to be linked to occupational/environmental metal exposure and ethnic susceptibility/vulnerability. A systematic overview of possible occupational and environmental metals causing interstitial pulmonary fibrosis and a detailed evaluation of vulnerable/susceptible populations may facilitate a broader understanding of potential underlying causes and highlight risks of disease predisposition.

AB - BACKGROUND: Idiopathic Intracranial Hypertension (IIH) is characterized by an elevation of intracranial pressure (ICP no identifiable cause. The aetiology remains largely unknown, however observations made in a number of recent clinical studies are increasing the understanding of the disease and now provide the basis for evidence-based treatment strategies. METHODS: The Embase, CDSR, CENTRAL, DARE and MEDLINE databases were searched up to 1st June 2018. We analyzed randomized controlled trials and systematic reviews that investigate IIH. RESULTS: Diagnostic uncertainty, headache morbidity and visual loss are among the highest concerns of clinicians and patients in this disease area. Research in this field is infrequent due to the rarity of the disease and the lack of understanding of the underlying pathology. CONCLUSIONS: This European Headache Federation consensus paper provides evidence-based recommendations and practical advice on the investigation and management of IIH. PMID- 30298347 TI - Refinements in Tear Trough Deformity Correction: Intraoral Release of Tear Trough Ligaments: Anatomical Consideration and Clinical Approach. AB - BACKGROUND: Correction of tear trough (TT) deformity is a crucial aspect of facial rejuvenation. Because the anatomical origins of TT deformity lie in the TT ligaments, which firmly attach the dermis to the periosteum, the release of TT ligaments should be considered when performing an etiological correction. The aim of this paper is to propose an alternative method for TT deformity correction, comprising use of filler together with the release of TT ligaments. This technique was compared to the procedure of only percutaneous filler. METHODS: From January 2014 to December 2015, 10 patients were enrolled in the study for recurrence of TT deformity. All the patients underwent TT ligament release and filler injections; all had been previously treated with percutaneous hyaluronic acid injection without ligament release. Under local anesthesia, the TT ligaments were detached using a blunt cannula introduced directly in the supra periosteal plane through an intraoral access. Once the ligament was released, the TT depression was evenly recontoured with a very small amount of filler. The clinical data, digital images, evaluations of outcomes, including patient satisfaction rates were collected and compared. RESULTS: Adding the procedure of TT ligament release to filler injections showed satisfactory results, avoiding an unnatural puffy appearance. The comparison between the two different methods showed improved outcomes and increased patient satisfaction with minor patient discomfort among those who underwent TT ligament release. CONCLUSION: Because TT ligaments are among the etiologic factors of TT deformity, they have a strong impact on procedures that are designed to improve TT deformity; therefore, TT ligament release should always be considered to obtain satisfactory, natural results.

PMID- 30298348 TI - Managing Periocular Filler-Related Syndrome Prior to Lower Blepharoplasty. AB - BACKGROUND: Hyaluronic acid (HA) fillers are extensively used in periocular volume augmentation. Although they have an excellent safety profile, filler related issues such as visibility/palpability, contour abnormalities, malar edema, and blue-gray dyschromia can occur. Recognition and management of filler related issues are critical prior to subsequent procedures. The clinical course of patients who had periocular HA filler-related issues and subsequently underwent lower eyelid blepharoplasty is described. METHODS: HA filler was dissolved with hyaluronidase (15-30 U/cm2) treatment. Visible lower eyelid fat prolapse after filler removal was corrected with transconjunctival blepharoplasty with fat repositioning and skin resurfacing. Complications and outcome were assessed and recorded. RESULTS: Twenty-three patients (46 eyelids) were treated. All presented with contour abnormalities, 19 with contour abnormalities and malar edema, and seven with blue-gray dyschromia. In 15 patients, one session of hyaluronidase completely dissolved the filler, and in eight patients, two sessions were required. Of these eight patients, edema resolved after the second hyaluronidase injection in four; in the remaining four, mild edema persisted despite absence of visible/palpable filler. Postblepharoplasty, 19 patients had an acceptable outcome with no complications (82.6%). Four patients had prolonged edema postoperatively; three had a resolution by 6 months. In 23 patients who had skin resurfacing procedures, there was no incidence of postinflammatory hyperpigmentation. CONCLUSIONS: HA filler-related issues need to be identified and managed prior to further intervention. Hyaluronidase treatment effectively dissolves the filler, but mild malar edema can persist. Outcomes are acceptable after subsequent blepharoplasty, but adequate patient counseling is necessary about expectations and limitations.

PMID- 30298349 TI - A haplotype variant of porcine IFIT2 increases poly(I:C)-induced activation of NF kappaB and ISRE-binding factors. AB - Interferon-induced protein with tetratricopeptide repeats (IFIT) 2 is associated with various viral infections and pathogenesis in humans and mice. However, there are few reports on IFIT2 in pigs and the polymorphic information remains unclear. Here, by using a direct PCR sequencing method, we identified four single nucleotide polymorphisms (SNPs), c.259G>A (p.Gly87Ser), c.520T>G (p.Phe174Val), c.571C>T (p.Pro191Ser), and c.879A>G (p.Glu293Glu), for the first time in the coding sequence of the porcine (p) IFIT2 gene from a Chinese local breed (Hebao pig), Western commercial pig breeds (Yorkshire and Landrace), and a Chinese developed breed (Beijing Black pig). SNP c.520T>G (p.Phe174Val) leads to the addition of a tetratricopeptide repeat motif, characteristic structure of the IFIT family. SNPs c.259G>A and c.520T>G are medium polymorphic loci (0.25 < polymorphic information content < 0.5) and distributed differently in Western pig breeds and the Chinese local pig, Hebao, which is well known for its strong resistance to disease. Additionally, they are completely linked. The four SNPs constituted five haplotypes with GTCA and AGCA as dominant. The haplotype variant AGCA, which is mainly present in Hebao pigs, significantly synergized the poly(I:C)-induced activation of transcription factors, including NF-kappaB and IFN-stimulated response element (ISRE)-binding factors, and the expression of interferon beta, indicating that the variant contributes to the induction or magnitude of the immune response upon viral infection. The data showed that variant AGCA might be useful in improving the resistance of pigs to viruses through marker-assisted selection.

AB - The effects of long-term soil fertilizations on nutrient and non-essential element concentrations in edible parts of three crops important in human diet were investigated repeating four treatments (biowaste compost, biowaste compost plus mineral nitrogen, mineral NPK, unfertilized control) for seven consecutive years (2007-2014). Fruits of Solanum lycopersicum cv San Marzano collected in 2011 and 2012, bulbs of Allium cepa cv Bianca di Pompei collected in 2012 and 2013, and bulbs of Foeniculum vulgare cv Orbit collected in 2014 were analyzed. Wide variations in element concentrations were observed along time and among species, with Ca, K, Mg, and Na higher in fennel bulbs and Cd, Cr, Mn, Ni, Pb, and Zn higher in tomato fruits, where Cd reached concentrations up to ninefold higher than the permitted values (EU Regulation n. 488/2014). Despite the enrichments in soil total Cu and available Cd, Fe, K, Mn, and Zn concentrations due to long-term fertilization with biowaste compost (alone or with mineral fertilizers), plants showed lower micronutrient and non-essential element concentrations in respect to those on unfertilized soils. Considering the potential toxicity for human beings of these mobile and persistent elements, the obtained findings reassure on the safe use of biowaste compost in agriculture. Overall, this study suggests the use of compost as the most advisable fertilization practice and highlights the need of multiple crops analysis in evaluating the effects of long-term soil fertilization on their chemical composition.

AB - Long non-coding RNAs (lncRNAs), which are longer than > 200 nt, perform various functions in a variety of important biological processes. The aim of this study is the investigation of relative expression levels of AK372815 putative pyridoxal reductase (PLR) gene and sense lncRNA AK370814 on four barley genotypes (Hasat, Beysehir 99, Konevi 98 and Tarm 92) in response to 150 mM salinity application during 3 days post-germination. Seeds were placed randomly in petri dishes containing (a) only H2O (control), (b) 150 mM NaCl, for 72 h. RNA isolation was carried out using TriPure(r) reagent from 150 mM salt-treated root and shoot samples. Relative expression levels of AK372815 PLR and sense lncRNA AK370814 were determined by qPCR. Results demonstrated that salinity affected the expression levels of both AK372815 PLR gene and sense lncRNA AK370814 during germination. Although expression levels of AK372815 PLR tended to be down regulated under salinity, expression levels of sense lncRNA AK370814 were up regulated. Another goal of this study is improvement of alternative approach to NGS technologies for determination of relative expression levels of sense lncRNAs under particular circumstances. This is the first report that demonstrates a relationship between lncRNA and vitamin B6 salvage pathway. PMID- 30298350 TI - Recent research progress of microRNAs in hypertension pathogenesis, with a focus on the roles of miRNAs in pulmonary arterial hypertension. AB - Hypertension is the most widespread disease in the world affecting humans and imparts a significant cardiovascular and renal risk to patients, and extensive research over the past few decades has enhanced our understanding of the underlying pathogenesis of hypertension. A growing number of studies have shown that miRNAs are involved in the pathological mechanisms of hypertension. This review summarizes the current understanding of miRNA-mediated modulation of gene expression in the hypertension pathogenesis in the past few years. A systematic review of PUBMED, EMBASE and SCOPUS was conducted for studies published in the past few years. The review covers three topics: miRNAs in pulmonary arterial hypertension (PAH), miRNAs and systemic arterial hypertension (SAH), miRNAs and application in hypertension. This review summarizes the current understanding of miRNA-mediated modulation in the hypertension pathogenesis in the past few years, with especially emphasis on miRNAs in PAH. We also discussed the roles of miRNAs in SAH, and the therapeutic applications of these miRNAs will be detailed discussed in this review. Evidence suggests that miRNAs are involved in the pathological mechanisms of hypertension, and the roles of miRNAs in the hypertension pathogenesis are confirmed. We need to further investigate the regulated roles of miRNAs in the pathogenesis of hypertension and the application of miRNAs in the diagnosis and treatment of this disease in the future.

AB - Date palm ash (DPA) and MgAl-layered double hydroxide (LDH) composites were synthesized by the co-precipitation method and characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), X-ray diffraction (XRD), and Brunauer-Emmett-Teller (BET). The DPA-MgAl-LDH (DPA/MgAl) composites were employed for the removal of methyl orange (MO) and eriochrome black-T (EBT) from aqueous phase. Incorporation of 33.33% (w/w) DPA into the layers of MgAl increased the surface area from 44.46 to 140.65 m2/g, which leads to the improved adsorption performance. The maximum adsorption capacity of DPA/MgAl (1:2) at 298 K was 242.98 and 425.16 (mg/g) for MO and EBT, respectively. The adsorption data of dyes were adequately fitted by a pseudo second-order and Langmuir isotherm model. The composite showed excellent reusability performance up to three cycles. Addition of DPA into MgAl-LDH resulted in an effective low-cost adsorbent for decontamination of dyes from wastewater. Graphical abstract ?. PMID- 30298354 TI - Characterization of composted sewage sludge during the maturation process: a pilot scale study. AB - This paper determines the impact of the maturation process of composted sewage sludge on the quality of the final product and assesses the stabilization effect. The samples of composted sewage sludge were taken from a wastewater treatment plant located in Pomerania in northern Poland. The sewage sludge was composted in an open windrow composting plant with the addition of straw and wood chips in the turning windrow. The aeration of the sewage sludge mixture was conducted based on two methods. The first phase (intensive degradation phase of 6 to 8 weeks) was characterized by frequently turning; the second phase for maturation used aeration channels (2 to 3 months). In three sampling campaigns samples were taken from the same windrow after 2 (no. 1), 8 (no. 2), and 12 weeks (no. 3) of maturation. Fresh samples were used for analyzing the stabilization parameter as static respiration activity (AT4). Furthermore, the values of pH, organic matter (OM), total organic carbon (TOC), elementary composition, nutrients, total content, and mobile forms of heavy metals were analyzed in the compost samples. A significant decrease was found in the stabilization parameter (AT4) during the maturation of tested materials. In turn, no significant differences were found in the elementary composition. The concentration of most metals increased in the final product. The total content of heavy metals in the final product did not exceed the limit values for the agricultural use of sewage sludge, compost from municipal waste, and for organic fertilizers. There were no significant changes in the percentage of bioavailable and mobile forms of heavy metals during compost maturation. Zinc was characterized by the highest level of mobile and bioavailable forms, which may cause bioaccumulation after the fertilization of soil. The study has shown that the process of maturation of compost from sewage sludge not affects changes in the content of heavy metal forms. The scope of this study has been planned on a wider scale for different variants of sewage sludge composting, in order to evaluate the process. PMID- 30298355 TI - Selenium (Se) uptake and dynamic changes of Se content in soil-plant systems. AB - In this study, we collected crop plants and associated soil samples and determined these for selenium (Se) content to analyze the uptake, enrichment, and translocation of Se in the different soil-plant systems of an agricultural production area, elucidate the dynamic mechanisms relating to Se content in plants and soil during different growth periods, and screen plants for high Se enrichment ability. Bioconcentration factor determinations indicated that the grains of rice have the strongest Se enrichment ability, followed by soybean and corn. Translocation factor analysis indicated that the grains of rice and corn have similar low translocation abilities for Se compared with soybean. Within the study area, the Se content in plants was closely related to the soil available Se content and varied considerably among different growth periods and plant organs. This study provides a theoretical basis for the development and utilization of local agricultural products. PMID- 30298356 TI - Evaluation of New Diagnostic Ratios of Naphthalenes and Fluorenes by Identifying Severely Weathered Oils Collected in Laboratory Simulations and Coastal Weathering Experiments. AB - The composition and physical properties of spilled oil have great changes during the seriously weathering process. It brings great difficulties to the source identification of oil spill. So, the stable and trustworthy diagnostic ratios (DRs) for accurate identification of severely weathered spilled oils are very important. The explosion of Sinopec pipeline happened on November 22, 2013 at Qingdao, China. Local beaches at Jiaozhou Bay were polluted by spilled oils. We have collected original spilled oil samples from an area free from human interference near the oil leakage point after the accident. Synchronized with actual beach weathering, laboratory experiments were conducted to simulate oil weathering for 360 days by using the collected original spilled oil samples. Based on the t test and the repeatability limit method, 65 DRs of naphthalenes and fluorenes were screened. Fifteen DRs, namely, C2Nap/(C2Nap + C3Nap), C2Nap/(C2Nap + C4Nap), C2Nap/total Nap, C3Nap/(C3Nap + C4Nap), C3Nap/total Nap, C4Nap/total Nap, C2Flu/(C2Flu + C3Flu), C2Flu/total Flu, C2Nap/(C2Nap + Flu), C2Nap/(C2Nap + C1Flu), C2Nap/(C2Nap + C2Flu), C2Nap/(C2Nap + C3Flu), C3Nap/(C3Nap + Flu),C3Nap/(C3Nap + C1Flu), total Nap/(total Nap + total Flu), have maintained remarkable stability during the simulated weathering experiments and field weathering process. These stable ratios can retain the characteristics of oil source during weathering. They are very beneficial to improve the accuracy of identifying the source of severely weathered oil and can be used as an effective supplement to existing index system for source identification. PMID- 30298357 TI - Measuring facial identity and emotion integration using the redundancy gain paradigm. AB - Early theories on face perception posit that invariant (i.e., identity) and changeable (i.e., expression) facial aspects are processed separately. However, many researchers have countered the hypothesis of parallel processes with findings of interactions between identity and emotion perception. The majority of tasks measuring interactions between identity and emotion employ a selective attention design, in which participants are instructed to attend to one dimension (e.g., identity) while the other dimension varies orthogonally (e.g., emotion), but is task irrelevant. Recently, a divided attention design (i.e., the redundancy gain paradigm) in which both identity and emotion are task relevant was employed to assess the interaction between identity and emotion. A redundancy gain is calculated by a drop in reaction time in trials in which a target from both dimensions is present in the stimulus face (e.g., "sad Person A"), compared with trials with only a single target present (e.g., "sad" or "Person A"). Redundancy gains are hypothesized to point to an interactive activation of both dimensions, and as such, could complement designs adopting a selective attention task. The initial aim of the current study was to reproduce the earlier findings with this paradigm on identity and emotion perception (Yankouskaya, Booth, & Humphreys, Attention, Perception, & Psychophysics, 74(8), 1692-1711, 2012), but our study failed to replicate the results. In a series of subtasks, multiple aspects of the design were manipulated separately in our goal to shed light on the factors that influence the redundancy gain effect in faces. A redundancy gain was eventually obtained after controlling for contingencies and stimulus presentation time. PMID- 30298358 TI - Expression and function analysis of a rice OsHSP40 gene under salt stress. AB - Heat shock proteins (HSPs) play essential roles in both plant growth and abiotic stress tolerance. In rice, OsHSP40 was recently reported to regulate programmed cell death (PCD) of suspension cells under high temperature. However, the expression and functions of OsHSP40 under normal growth or other abiotic stress conditions is still unknown. We reported the expression and function of a rice OsHSP40 gene under salt stress. Homologous proteins of OsHSP40 were collected from the NCBI database and constructed the neighbor-joining (NJ) phylogenetic tree. The expression pattern of OsHSP40 was detected by qRT-PCR under NaCl (150 mM) treatment. Then, identified a rice T-DNA insertion mutant oshsp40. At last, we compared and analyzed the phenotypes of oshsp40 and wild type under salt stress. OsHSP40 was a constitutively expressed small HSP (sHSP) gene and was close related to other plant sHSPs. Moreover, the expression of OsHSP40 was regulated by salt, varying across time points and tissues. Furthermore, the growth of T-DNA insertion mutant of OsHSP40 (designated as oshsp40) was suppressed by NaCl (150 mM) compared with that of the WT at seedling stage. Detailed measurement showed root and shoot length of the oshsp40 seedlings were significantly shorter than those of the WT seedlings under NaCl stress. In addition, the pot experiment results revealed that seedlings of oshsp40 withered more seriously compared with those of WT after NaCl treatment and recovery, and that survival rate and fresh weight of oshsp40 seedlings were significantly reduced. Taken together, these data suggested that OsHSP40 had multiple functions in rice normal growth and abiotic stress tolerance. PMID- 30298359 TI - Functional evaluation of alternative splicing in the FAM190A gene. AB - The human FAM190A gene undergoes frequent alteration in human cancer, most commonly involving in-frame deletions in exon 9 or exons 9 & 10. These deletions form novel peptide sequences, serving as presumptive cancer-specific neo antigens. However, it remains elusive whether these in-frame deletions of FAM190A could induce oncogenic properties in vivo. In this study, we aimed to explore the functional significance of in-frame deletions in FAM190A genes. We generated two deletion mutant forms, FAM190ADeltaexon9 and FAM190ADeltaexon9&10, and examined their gain-of-function effects in vitro and in vivo. Global transcript profiling in NIH3T3 cells revealed that the transcripts displaying altered expression following introduction of FAM190ADeltaexon9 and FAM190ADeltaexon9&10 were significantly enriched for genes assigned to cellular movement and cell-to-cell signaling, respectively. Furthermore, ectopic expression of FAM190ADeltaexon9 and FAM190ADeltaexon9&10 induced in vivo tumor formation in nu/nu mice. Taken together, our results are the first to demonstrate the in vivo oncogenic properties of in-frame deletions in the FAM190A gene and indicate that these transcript variants might be clinically applicable as therapeutic targets in patients with cancer. PMID- 30298360 TI - Hepatitis C virus cell culture models: an encomium on basic research paving the road to therapy development. AB - Chronic hepatitis C virus (HCV) infections affect 71 million people worldwide, often resulting in severe liver damage. Since 2014 highly efficient therapies based on directly acting antivirals (DAAs) are available, offering cure rates of almost 100%, if the infection is diagnosed in time. It took more than a decade to discover HCV in 1989 and another decade to establish a cell culture model. This review provides a personal view on the importance of HCV cell culture models, particularly the replicon system, in the process of therapy development, from drug screening to understanding of mode of action and resistance, with a special emphasis on the contributions of Ralf Bartenschlager's group. It summarizes the tremendous efforts of scientists in academia and industry required to achieve efficient DAAs, focusing on the main targets, protease, polymerase and NS5A. It furthermore underpins the importance of strong basic research laying the ground for translational medicine. PMID- 30298361 TI - The effect of non-steroidal anti-inflammatory drugs on the osteogenic activity in osseointegration: a systematic review. AB - Non-steroidal anti-inflammatory drugs are commonly used in implant dentistry for management of post-operative pain. The objective of this systematic review was to analyse the effect of non-steroidal anti-inflammatory drugs on the osteogenic activity of osteoblasts with an emphasis on its effect on osseointegration. A systematic literature search for in vitro, animal models, and clinical trials was conducted using Ovid, PubMed, Scopus, and Web of Science databases. Articles published since the introduction of selective COX-2 inhibitors, between January 1999 and July 2018, were selected. The integrated search followed the PRISMA statement with the following key terms: non-steroidal anti-inflammatory drug/s, titanium, osseointegration, and osteoblast. The review is registered at PROSPERO database: CRD42016051448. The titles and abstracts of each research article in the initial search (n = 875) were independently screened by two reviewers. A third independent reviewer reviewed the articles that were included by one but excluded by the other reviewer. This resulted in the cataloguing of 79 full-text manuscripts where the articles were assessed for the following criteria: the study investigates the effects of NSAIDs on osteoblasts, explores the COX pathway and its effect on osteogenic activity, and compares the effects of NSAIDs on osteoblasts with a control group. A total of 13 articles have been included for qualitative synthesis. There is a lack of consensus in the literature to explicitly conclude that there is a relationship between the use of post operative NSAIDs and failed osseointegration; however, osseointegration does not appear to be negatively affected by NSAIDs in the human clinical studies. PMID- 30298362 TI - Incidence of Stevens-Johnson syndrome/toxic epidermal necrolysis among new users of different individual drugs in a European population: a case-population study. AB - PURPOSE: To estimate the specific incidences of Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) among new users of drugs frequently reported to be associated with this serious event. METHODS: We performed a case-population approach, which combined data from a registry of SJS/TEN cases from the Madrid region (numerator) during the study period 2005-2015 and a primary healthcare database from the same catchment population. The proportion of new users of drugs estimated in the primary healthcare database was stratified by calendar year, sex and age (5-year bands), and then applied to the same strata of Madrid's population census to compute the number of new users (denominator). Incidences were re-estimated using only cases in which the concerned drug had a probable or very probable causal relationship. RESULTS: A total of 44 SJS/TEN cases aged > 14 years were registered during the study period. The highest SJS/TEN incidence was found for phenytoin with 68.9 per 100,000 new users (95% CI 27.7-141.9), followed by dexamethasone (5.48; 1.49-14.03), allopurinol (3.29; 1.07-7.67) and cotrimoxazole (3.19; 0.87-8.16). Considering only probable and very probable cases, the incidences hardly changed, except for dexamethasone, which was left without cases. Pantoprazole, levofloxacin and lorazepam showed incidences between 1 per 100,000 and 1 per 1,000,000 new users. Ibuprofen, amoxicillin-clavulanic acid, metamizole, amoxicillin, paracetamol and omeprazole showed incidences around 1 per one million new users. CONCLUSIONS: Phenytoin was the drug with the highest incidence of SJS/TEN, followed by allopurinol and cotrimoxazole. For the rest of the drugs, the estimated incidences were below 1 in 100,000 new users. PMID- 30298363 TI - The intact nephron hypothesis as a model for renal drug handling. AB - PURPOSE: The intact nephron hypothesis (INH) states that impaired renal function results from a reduction in the number of complete (intact) nephrons. Under this model, renal drug clearance is assumed to be a linear function of glomerular filtration while tubular handling is ignored. The aims of this study were to systematically review published studies designed to test the INH and to assess the strength of the study designs used. METHODS: A systematic literature search was conducted in MEDLINE, EMBASE and Google Scholar. Studies specifically designed to understand the relationship between glomerular and tubular function across different levels of renal function were included. Studies that found a linear relationship between GFR and tubular clearance were deemed to support the INH while studies that found a non-linear relationship did not support the INH. Study design was accessed using a bespoke strength of evidence score. RESULTS: Thirty studies met the criteria for inclusion. Of these, 24 did not support the INH. Studies that did not support the INH used methods for measuring tubular clearance that were more robust and included subjects with a wider range of GFR values than studies that supported the INH. DISCUSSION: Our results suggest that the INH may not be a suitable general model for renal drug handling, particularly for drugs that are eliminated by tubular mechanisms. Further studies to assess the clinical importance of a non-linear relationship between drug clearance and GFR are warranted. PMID- 30298364 TI - Prevention of venous thrombosis after electrophysiology procedures: a survey of national practice. AB - PURPOSE: Femoral venous access is required for most electrophysiology procedures. Limited data are available regarding post-procedure venous thromboembolism (VTE), specifically deep vein thrombosis (DVT) and pulmonary embolism (PE). Potential preventative strategies are unclear. We aimed to survey Canadian centers regarding incidence of VTE and strategies for prevention of VTE after procedures that do not require post-procedure anticoagulation. METHODS: An online survey was distributed to electrophysiologists representing major Canadian EP centers. Participants responded regarding procedural volume, incidence of VTE post procedure, and their practice regarding pharmacological and non-pharmacological peri-procedural VTE prophylaxis. RESULTS: The survey included 17 centers that performed a total of 6062 procedures in 2016. Ten patients (0.16%) had VTE (including 9 DVTs and 6 PEs) after diagnostic electrophysiology studies and right sided ablation procedures excluding atrial flutter. Five centers (41.6%) administered systemic intravenous heparin during both diagnostic electrophysiology studies and right-sided ablation procedures. For patients taking oral anticoagulants, 10 centers (58.8%) suspend therapy prior to the procedure. Two centers (11.8%) routinely prescribed post-procedure pharmacologic prophylaxis for VTE. Four centers (23.5%) used compression dressings post procedure and all prescribed bed rest for a maximum of 6 h. Of the variables collected in the survey, none were found to be predictive of VTE. CONCLUSIONS: VTE is not a common complication of EP procedures. There is significant variability in the strategies used to prevent VTE events. Future research is required to evaluate strategies to reduce the risk of VTE that may be incorporated into EP practice guidelines.

PMID- 30298365 TI - Long-term survival of patients after ipilimumab and hypofractionated brain radiotherapy for brain metastases of malignant melanoma: sequence matters. AB - PURPOSE: Since the introduction of ipilimumab (IPI) for the treatment of patients with metastatic malignant melanoma, we have observed remarkable responses after hypofractionated whole brain irradiation (WBRT) or stereotactic radiotherapy (STX) for brain metastases of malignant melanoma. We sought to investigate the impact of the sequence of these treatment modalities. METHODS: We retrospectively evaluated the survival of melanoma patients with brain metastases who were treated with WBRT or STX and received IPI in close temporal relation between October 2010 and March 2015. Follow-up was obtained until November 2016. A total of 27 patients with advanced melanoma and brain metastases who were treated with WBRT before 2010, and who had not received IPI, served as historical controls. RESULTS: We identified a total of 41 patients of whom 15 were treated with STX, 7 with a combination of STX and WBRT and 19 with WBRT alone. All patients received at least 2 doses of IPI. The median time interval between radiotherapy and IPI was 2 months. Patients treated with IPI after radiotherapy had a censored median survival of 11 months, compared with 3 months for the patients who received IPI prior to radiotherapy. Patients who received IPI before radiotherapy showed a similar survival as historical controls, who had not received IPI. We observed long-term survivors after radiotherapy of brain metastases followed by IPI. CONCLUSIONS: These data suggest that the sequence of RT and immune checkpoint inhibition with IPI may be crucial for the success of combined modality treatment of melanoma brain metastases.

PMID- 30298368 TI - Can regional training courses reduce interobserver variability? AB - Cardiovascular disease (CVD) is the principal cause of death worldwide. Noninvasive studies have been used for the evaluation of CVD. Ensuring an accurate diagnosis of CVD requires well-trained and qualified professionals. IAEA has implemented regional training courses which are mainly aimed at professionals from countries with less economic development in order to raise their professional level so that it is in accordance with international standards and thus be able to homogenize the practice of nuclear cardiology globally.

PMID- 30298371 TI - Agreement between left ventricular ejection fraction assessed in patients with gated IQ-SPECT and conventional imaging. AB - BACKGROUND: The aim of the study was to assess the agreement between the left ventricular ejection fraction (LVEF) values obtained with IQ-SPECT and those obtained with a conventional gamma camera equipped with low-energy high resolution (LEHR), considered as the method of reference. METHODS: Gated-stress MPI using 99mTc-tetrofosmin was performed in 55 consecutive patients. The patients underwent two sequential acquisitions (Method A and B) performed on Symbia-IQ SPECT with different acquisition times and one (Method C) on a Ecam SPECT equipped with LEHR collimators. The values of the different datasets were compared using the Bland-Altman analysis method: the bias and the limits of agreement (LA) were estimated in a head-to-head comparison of the three protocols. RESULTS: In the (Method A-Method C) comparison for LVEF, the bias was 3.8% and the LAs ranged from - 9.3% to 16.8%. The agreement was still lower between Method B and C, whilst only slightly improved when Methods A and B were compared. CONCLUSIONS: The wide amplitude in LA intervals of about 30% indicates that IQ and LEHR GSPECT are not interchangeable. The values obtained with IQ SPECT should only be used with caution when evaluating the functional state of the heart. PMID- 30298372 TI - Rubidium-82 positron emission tomography for detection of acute doxorubicin induced cardiac effects in lymphoma patients. AB - BACKGROUND: Doxorubicin is a cornerstone in lymphoma treatment, but is limited by dose-dependent cardiotoxicity. Rubidium-82 positron emission tomography (82Rb PET) assesses coronary microvascular function through absolute quantification of myocardial perfusion and myocardial perfusion reserve (MPR). Doxorubicin-induced microvascular injury represents a potential early marker of cardiotoxicity. METHODS AND RESULTS: We included 70 lymphoma patients scheduled for doxorubicin based treatment. Cardiotoxicity was evaluated with 82Rb PET myocardial perfusion imaging during rest and adenosine stress before chemotherapy and shortly after the first doxorubicin exposure. Patients with a MPR decline > 20% were defined as having a low threshold for cardiotoxicity. In the 54 patients with complete data sets, MPR was significantly lower after the initial doxorubicin exposure (2.69 vs 2.51, P = .03). We registered a non-significant decline in stress perfusion (3.18 vs 3.02 ml/g/min, P = .08), but no change in resting myocardial perfusion. There were 13 patients with a low cardiotoxic threshold. These patients had a significantly higher age, but were otherwise similar to the remaining part of the study population. CONCLUSION: Decreases in MPR after initial doxorubicin exposure in lymphoma patients may represent an early marker of doxorubicin-induced cardiotoxicity. The prognostic value of acute doxorubicin-induced changes in MPR remains to be investigated. PMID- 30298373 TI - Pentagalloyl Glucose and Its Functional Role in Vascular Health: Biomechanics and Drug-Delivery Characteristics. AB - Pentagalloyl glucose (PGG) is an elastin-stabilizing polyphenolic compound that has significant biomedical benefits, such as being a free radical sink, an anti inflammatory agent, anti-diabetic agent, enzymatic resistant properties, etc. This review article focuses on the important benefits of PGG on vascular health, including its role in tissue mechanics, the different modes of pharmacological administration (e.g., oral, intravenous and endovascular route, intraperitoneal route, subcutaneous route, and nanoparticle based delivery and microbubble-based delivery), and its potential therapeutic role in vascular diseases such as abdominal aortic aneurysms (AAA). In particular, the use of PGG for AAA suppression and prevention has been demonstrated to be effective only in the calcium chloride rat AAA model. Therefore, in this critical review we address the challenges that lie ahead for the clinical translation of PGG as an AAA growth suppressor. PMID- 30298374 TI - Evaluation of Drug-Loaded Gold Nanoparticle Cytotoxicity as a Function of Tumor Vasculature-Induced Tissue Heterogeneity. AB - The inherent heterogeneity of tumor tissue presents a major challenge to nanoparticle-mediated drug delivery. This heterogeneity spans from the molecular (genomic, proteomic, metabolomic) to the cellular (cell types, adhesion, migration) and to the tissue (vasculature, extra-cellular matrix) scales. In particular, tumor vasculature forms abnormally, inducing proliferative, hypoxic, and necrotic tumor tissue regions. As the vasculature is the main conduit for nanotherapy transport into tumors, vasculature-induced tissue heterogeneity can cause local inadequate delivery and concentration, leading to subpar response. Further, hypoxic tissue, although viable, would be immune to the effects of cell cycle specific drugs. In order to enable a more systematic evaluation of such effects, here we employ computational modeling to study the therapeutic response as a function of vasculature-induced tumor tissue heterogeneity. Using data with three-layered gold nanoparticles loaded with cisplatin, nanotherapy is simulated interacting with different levels of tissue heterogeneity, and the treatment response is measured in terms of tumor regression. The results quantify the influence that varying levels of tumor vascular density coupled with the drug strength have on nanoparticle uptake and washout, and the associated tissue response. The drug strength affects the proportion of proliferating, hypoxic, and necrotic tissue fractions, which in turn dynamically affect and are affected by the vascular density. Higher drug strengths may be able to achieve stronger tumor regression but only if the intra-tumoral vascular density is above a certain threshold that affords sufficient transport. This study establishes an initial step towards a more systematic methodology to assess the effect of vasculature induced tumor tissue heterogeneity on the response to nanotherapy. PMID- 30298375 TI - Backbone resonance assignment for the N-terminal region of bacterial tRNA-(N1G37) methyltransferase. AB - Bacterial tRNA (guanine37-N1)-methyltransferase (TrmD) is an important antibacterial target due to its essential role in translation. TrmD has two domains connected with a flexible linker. The N-terminal domain (NTD) of TrmD contains the S-adenosyl-L-methionine (SAM) cofactor binding site and the C terminal domain is critical for tRNA binding. Here we report the backbone NMR resonance assignments for NTD of Pseudomonas aeruginosa TrmD. Its secondary structure was determined based on the assigned resonances. Relaxation analysis revealed that NTD existed as dimers in solution. NTD also exhibited thermal stability in solution. Its interactions with SAM and other compounds suggest it can be used for evaluating SAM competitive inhibitors by NMR. PMID- 30298376 TI - Marinactinospora rubrisoli sp. nov., isolated from red soil. AB - A novel Marinactinospora strain JX35-4T was isolated from red soil which was collected from Wushan, northern Jiangxi Province, China. Analysis of the 16S rRNA gene sequences showed that strain JX35-4T belongs to the genus Marinactinospora and formed a distinct phylogenetic clade with Marinactinospora thermotolerans SCSIO 00652T and Marinactinospora endophytica YIM 690053T with sequence similarity of 96.97% and 96.42%, respectively. The strain was Gram-positive and formed branched substrate hyphae with no fragmentation, and abundant aerial hyphae that differentiated into long spore chains, and short rod-shaped spores. Growth occurred at 20-45 degrees C, pH 7.0-12.0 and in the presence of 0-7.5% (w/v) NaCl. The genomic DNA G + C content was determined to be 68.3 mol%. The cell wall of strain JX35-4T contained meso-diaminopimelic acid and xylose. Polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylinositol mannosides and one unidentified phospholipid. The major fatty acids of strain JX35-4T consisted of anteiso-C17:0 and iso-C16:0. Major menaquinones were MK-9(H10), MK-12 and MK-10(H2). Based on the polyphasic data, strain JX35-4T (= CGMCC 4.7382T = DSM 104977T) is concluded to represent a novel species of the genus Marinactinospora, for which the name Marinactinospora rubrisoli sp. nov. is proposed. PMID- 30298377 TI - Usefulness of both PET/CT with F18-FDG and whole-body diffusion-weighted imaging in cancer screening: a preliminary report. AB - OBJECTIVE: Positron emission tomography/computed tomography (PET/CT) with fluorodeoxyglucose (F18-FDG) is useful for the detection of malignant lesions, including metastatic lesions, and this technique is widely used in cancer screening. However, this approach may occasionally yield false-positive and false negative findings. At our PET center, to increase the accuracy of PET/CT, we use PET/CT and whole-body diffusion-weighted imaging (WB-DWI) together. This study aimed to assess the usefulness of this combination. METHODS: We examined 29 subjects with confirmed diagnosis. All of them had undergone PET/CT and WB-DWI on the same day. Twenty-seven of them also underwent ultrasonography, blood testing, and upper gastrointestinal series on the same day and two fecal occult blood tests on another day. WB-DWI was performed on a 1.5-T MRI unit with a b value of 0 and 800 or 1000 s/mm2. For all 29 cases, PET/CT and WB-DWI were classified to be positive or negative, and the diagnostic ability was calculated for each modality. RESULTS: Among the 29 subjects, 17 had malignant tumors and 12 had benign tumors or no abnormalities. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of PET/CT were 65%, 25%, 55%, 33%, and 48%, respectively; while the corresponding values for WB-DWI were 59%, 100%, 100%, 63%, and 76%, respectively. By considering the result to be negative when PET/CT findings were positive but WB-DWI findings were negative, specificity increased from 25 to 100%, and accuracy increased from 48 to 76%. On the other hand, by considering the result to be positive when the findings of either PET/CT or WB-DWI were positive, sensitivity increased from 65 to 76%, and accuracy increased from 48 to 55%. CONCLUSIONS: Our results suggest that using both PET/CT and WB-DWI together can increase accuracy in cancer screening. However, this approach was not able to detect malignant lesions in some cases, indicating that there were limitations with imaging certain organs. Therefore, it is important to further understand the features of PET/CT and WB DWI and use them appropriately for each organ. Additionally, given that the study sample was relatively small, further research is needed to validate these findings.

PMID- 30298379 TI - Mechanical thromboprophylaxis would suffice after total knee arthroplasties in Asian patients? AB - PURPOSE: Our prospective study evaluated the incidence and location of deep vein thrombosis (DVT), the risk factors for PE and the natural history of DVT after TKA in patients who have received only mechanical compression device without having any chemical thromboprophylaxis or therapeutic treatment. METHODS: We studied 408 consecutive patients (691 knees) who underwent primary TKA; 283 patients had one-stage bilateral TKAs and 125 had unilateral TKAs. Coagulation assays, the full blood count and blood typing tests, and serum chemical profiles were undertaken in all patients on three separate occasions. Molecular genetic testing was performed preoperatively to detect the genetic traits involving DVT. Bilateral simultaneous or unilateral venograms were carried out at 6 or 7 days after operation. Perfusion lung scanning was undertaken before and at 7 or 8 days after operation. RESULTS: In the 691 venograms in 408 patients, only 4 knees (0.6%) were positive for fresh thrombi. In the 4 knees with DVT, thrombi were located in the calf veins. We observed factor V Leiden mutation, antithrombin-III level, and prothrombin promoter G20210A mutation were absent in all patients. We saw no relationship between DVT and coagulation or thrombophilic data. No pulmonary embolism (PE) occurred as shown by negative perfusion lung scan and absence of symptoms. CONCLUSION: We concluded that the combinations of absent thrombophilic polymorphisms with low clinical prothrombotic risk factors led to low prevalence of DVT and virtually absent PE after TKA in the current series of patients, who had received mechanical compression device only without chemical thromboprophylaxis. PMID- 30298380 TI - Effects of Thai traditional dance on balance performance in daily life among older women. AB - BACKGROUND: Previous research indicates that dance training may improve balance among older adults. AIMS: This study investigated the effects of Thai traditional dance on balance performance among older women. METHODS: Forty-three women aged 60-80 years, with mean scores between 45 and 52 points on the Berg Balance Scale (BBS), were recruited and randomly assigned into two groups: a Thai traditional dance group (TTDG) (n = 22) and a control group (CG) (n = 21). TTD program comprised three dance sessions of 30-60 min per week over the course of 12 weeks while the CG kept their normal daily activities. Balance performance was assessed using standardized tests including the NeuroCom Balance Master(r) System (Version 9.2), the Timed Up and Go Test (TUG) and the BBS. RESULTS: The results revealed that overall balance was better for those in TTDG compared to the CG. There was a significantly lower sway velocity and faster weight transfer in the Sit-to-Stand Test (p <= 0.001) for those in the dance group. TTDG had quicker turn time in the Step Quick Turn Test (p <= 0.001), improved Step Up Over Test and Walk Across Test, faster movement time, walking speed, and a better score in the TUG after training (p <= 0.001). DISCUSSION: A 3-weekly Thai traditional dance intervention significantly improved balance and mobility among older community-dwelling women as compared to normal daily activities. CONCLUSION: Thai traditional dance could potentially prevent age-related mobility and balance decline and its related fall risk. PMID- 30298381 TI - Radiotherapy in palliation of thoracic tumors: a phase I-II study (SHARON project). AB - The main clinical goal for patients with advanced or metastatic thoracic cancer is palliation of tumor-related symptoms and improvement of quality of life. The aim of this phase I-II trial was to define the maximum tolerated dose (MTD) of a short-course of palliative radiotherapy (RT) and to evaluate its efficacy in terms of palliative response. A phase I trial was planned with escalating dose increments. Total doses ranged from 16 to 20 Gy delivered (BID) in two consecutive days. Dose limiting toxicity was defined as any acute grade >= 3 toxicity based on the RTOG scale. MTD was used in the phase II trial to evaluate the efficacy of this regimen using a two stage Simon's design. Fifty-four patients were enrolled. The upper dose level of 20 Gy was defined as the MTD. In patients treated with this dose, the overall palliative response rate was 96.5% (CI 0.95: 81.3-99.9%). Complete pain relief rate was 50.0%. Median survival without symptomatic progression was 3 months. The tested short course accelerated regimen was well tolerated and effective in the palliative setting of metastatic or locally advanced chest cancer. A phase III trial is ongoing to validate this RT schedule.Trial registration: NCT03465553. PMID- 30298382 TI - Longitudinal Kinematic Evaluation of Pharyngeal Swallowing Impairment in Thyroidectomy Patients. AB - The aim of this study was to assess pharyngeal swallowing impairments in thyroidectomy patients and to delineate the contributory kinematic components. Forty consecutive patients (mean age = 47.33 years) and fourteen age- and sex matched heathy adult volunteers (mean age = 42.64 years) participated in this study. A videofluoroscopic swallowing study (VFSS) was performed 1 day prior to surgery, and at 1 week and 3 months post-surgery. VFSS images were evaluated using the Modified Barium Swallowing Impairment Profile (MBSImp). Kinematic and temporal aspects of swallowing were characterized by measurement of maximum hyoid and laryngeal excursion, pharyngeal transit duration, laryngeal response duration (LRD), and laryngeal closure duration at each three time-points. At 1 week post surgery, only pharyngeal impairment was significantly deteriorated than pre surgery (p = 0.001). However, at 3 months, a significant improvement was observed to pre-surgery level (p = 0.01). Post-surgery, maximum hyoid excursion was significantly reduced in patients compared controls (p = 0.001). Although the maximal distance of the hyoid and the laryngeal excursion was shorter than before surgery, laryngeal excursion at all three time-points was similar to that of controls. At all three time-points, LRD was significantly longer in patients than in controls (p = 0.01). Following thyroidectomy, pharyngeal aspects of swallowing as measured by the MBSImp and kinematic aspects of swallowing were reduced with incomplete recovery at 3 months. These exploratory data may guide decision regarding management of pharyngeal swallowing impairment with patients undergoing total thyroidectomy. PMID- 30298383 TI - Repeated KI Prophylaxis in Case of Prolonged Exposure to Iodine Radioisotopes: Pharmacokinetic Studies in Adult Rats. AB - PURPOSE: To propose a new and effective dose regimen for stable potassium iodide (KI) repeated prophylaxis in case of prolonged exposure to radioactive iodine. METHODS: The pharmacokinetics of iodine was determined in rats by compartmental analyses after intravenous and oral administrations of the optimal dose of 1 mg/kg KI, which was previously selected in a dose-effect study. The thyroid protection against iodine-125 incorporation was followed during 24 h after a single oral dosing of KI. A repeated KI prophylaxis was modeled using initial estimates of iodine pharmacokinetic parameters. RESULTS: A dose regimen consisting in administrations of 1 mg/kg daily for 8 days was selected and studied. Plasma iodine concentrations predicted by simulation were verified by experimental data and varied after the third dose of KI between 174 and 1190 MUg/l. The inhibition study of iodine-125 binding in the thyroid as a function of the time showed that the protection effect of KI could be correlated to stable iodine plasma concentrations. Hence, a theoretical decrease in iodine-125 thyroid uptake from 63 to 88% could be achieved in a 24 h-interval between two KI doses. CONCLUSION: Given the satisfactory levels of thyroid protection, this dose regimen could be envisaged in order to extent KI indications for repeated prophylaxis.

PMID- 30298385 TI - The combination of everolimus and terameprocol exerts synergistic antiproliferative effects in endometrial cancer: molecular role of insulin-like growth factor binding protein 2. AB - Oncogenic PIK3CA mutations are common in endometrial cancers, and the PI3K/AKT/mTOR pathway is targetable by drugs. We sought to investigate whether the combination of an mTOR inhibitor, everolimus (RAD001), and an AKT inhibitor, terameprocol (M4N), exerts better antiproliferative effects in endometrial cancer. The molecular mechanisms underlying their pharmacological action were also examined. The combination of RAD001 and M4N exerted in vitro synergistic effects on cell viability, apoptosis, and expression of IGFBP2 in endometrial cancer cells. Mechanistically, the Sp1 site on the IGFBP2 promoter was required for RAD001- and M4N-induced downregulation. IGFBP2 protein expression was higher in endometrial cancer than in the normal endometrium (P < 0.001). Furthermore, elevated IGFBP2 histoscores were significantly associated with a lower overall survival (P = 0.021). In conclusion, our in vitro results demonstrate that RAD001 and M4N exert synergistic antiproliferative effects against endometrial cancer cells, which appeared to be mediated by the inhibition of IGFBP2, a key anti apoptotic regulator. Further clinical studies of this drug combination in patients with endometrial cancer may be warranted, especially in the presence of PIK3CA and IGFBP2 aberrations. KEY MESSAGES: RAD001 and M4N synergistically suppress endometrial cancer growth. IGFBP2 is overexpressed in endometrial cancer. The combination of RAD001 and M4N significantly reduces IGFBP2 overexpression. Sp1 binding site on the IGFBP2 promoter is required for RAD001- and M4N-induced downregulation. High IGFBP2 histoscore in endometrial cancer portends a poor prognosis. PMID- 30298387 TI - Darvadstrocel: A Review in Treatment-Refractory Complex Perianal Fistulas in Crohn's Disease. AB - Darvadstrocel (Alofisel(r)) consists of a suspension of expanded human allogeneic adipose-derived mesenchymal stem cells (eASCs). It is the first mesenchymal stem cell (MSC) advanced therapy approved in the EU for the treatment of complex perianal fistulas in adult patients with non-active/mildly active luminal Crohn's disease, when fistulas have shown an inadequate response to >= 1 conventional or biologic therapy. In the pivotal phase 3 ADMIRE-CD trial in this difficult-to treat patient population, after standard-of-care fistula conditioning, add-on therapy with a single dose of darvadstrocel (120 million eASC) administered into the tissue surrounding complex perianal fistulas was significantly more effective than placebo (saline), with the darvadstrocel group having a higher combined remission rate (i.e. clinically-assessed fistula closure plus MRI-assessed absence of abscesses) at 24 weeks in intent-to-treat (ITT primary analysis), modified ITT and per-protocol analyses. Clinical remission was maintained in > 50% of patients at 52 weeks' follow-up. Given the very limited treatment options available for this difficult-to-treat rare condition, darvadstrocel is a promising, novel, minimally invasive therapy that represents an important advance in the therapeutic options for complex perianal fistulas in adult patients with non-active/mildly active luminal Crohn's disease when fistulas have shown an inadequate response to >= 1 conventional or biologic therapy. PMID- 30298388 TI - BABY BOOM (BBM): a candidate transcription factor gene in plant biotechnology. AB - Plants have evolved a number of transcription factors, many of which are implicated in signaling pathways as well as regulating diverse cellular functions. BABY BOOM (BBM), transcription factors of the AP2/ERF family are key regulators of plant cell totipotency. Ectopic expression of the BBM gene, originally identified in Brassica napus, has diverse functions in plant cell proliferation, growth and development without exogenous growth regulators. The BBM gene has been implicated to play an important role as a gene marker in multiple signaling developmental pathways in plant development. This review focuses on recent advances in our understanding of a member of the AP2 family of transcription factor BBM in plant biotechnology including plant embryogenesis, cell proliferation, regeneration, plant transformation and apogamy. Recent discoveries about the BBM gene will inevitably help to unlock the long-standing mysteries of different biological mechanisms of plant cells.

PMID- 30298389 TI - Predicting the Effect of Mutations on Protein Folding and Protein-Protein Interactions. AB - The function of a protein is largely determined by its three-dimensional structure and its interactions with other proteins. Changes to a protein's amino acid sequence can alter its function by perturbing the energy landscapes of protein folding and binding. Many tools have been developed to predict the energetic effect of amino acid changes, utilizing features describing the sequence of a protein, the structure of a protein, or both. Those tools can have many applications, such as distinguishing between deleterious and benign mutations and designing proteins and peptides with attractive properties. In this chapter, we describe how to use one of such tools, ELASPIC, to predict the effect of mutations on the stability of proteins and the affinity between proteins, in the context of a human protein-protein interaction network. ELASPIC uses a wide range of sequential and structural features to predict the change in the Gibbs free energy for protein folding and protein-protein interactions. It can be used both through a web server and as a stand-alone application. Since ELASPIC was trained using homology models and not crystal structures, it can be applied to a much broader range of proteins than traditional methods. It can leverage precalculated sequence alignments, homology models, and other features, in order to drastically lower the amount of time required to evaluate individual mutations and make tractable the analysis of millions of mutations affecting the majority of proteins in a genome. PMID- 30298390 TI - Accurate Calculation of Free Energy Changes upon Amino Acid Mutation. AB - Molecular dynamics based free energy calculations allow for a robust and accurate evaluation of free energy changes upon amino acid mutation in proteins. In this chapter we cover the basic theoretical concepts important for the use of calculations utilizing the non-equilibrium alchemical switching methodology. We further provide a detailed step-by-step protocol for estimating the effect of a single amino acid mutation on protein thermostability. In addition, the potential caveats and solutions to some frequently encountered issues concerning the non equilibrium alchemical free energy calculations are discussed. The protocol comprises details for the hybrid structure/topology generation required for alchemical transitions, equilibrium simulation setup, and description of the fast non-equilibrium switching. Subsequently, the analysis of the obtained results is described. The steps in the protocol are complemented with an illustrative practical application: a destabilizing mutation in the Trp cage mini protein. The concepts that are described are generally applicable. The shown example makes use of the pmx software package for the free energy calculations using Gromacs as a molecular dynamics engine. Finally, we discuss how the current protocol can readily be adapted to carry out charge-changing or multiple mutations at once, as well as large-scale mutational scans. PMID- 30298391 TI - Protocols for the Molecular Evolutionary Analysis of Membrane Protein Gene Duplicates. AB - Gene duplication is an important process in the evolution of gene content in eukaryotic genomes. Understanding when gene duplicates contribute new molecular functions to genomes through molecular adaptation is one important goal in comparative genomics. In large gene families, however, characterizing adaptation and neofunctionalization across species is challenging, as models have traditionally quantified the timing of duplications without considering underlying gene trees. This protocol combines multiple approaches to detect adaptation in protein duplicates at a phylogenetic scale. We include a description of models for gene tree-species tree reconciliation that enable different types of inference, as well as a practical guide to their use. Although simulation-based approaches successfully detect shifts in the rate of duplication/retention, the conflation between the duplication and retention processes, the distinct trajectories of duplicates under non-, sub-, and neofunctionalization, as well as dosage effects offer hitherto unexplored analytical avenues. We introduce mathematical descriptions of these probabilities and offer a road map to computational implementation whose starting point is parsimony reconciliation. Sequence evolution information based on the ratio of nonsynonymous to synonymous nucleotide substitution rates (dN/dS) can be combined with duplicate survival probabilities to better predict the emergence of new molecular functions in retained duplicates. Together, these methods enable characterization of potentially adaptive candidate duplicates whose neofunctionalization may contribute to phenotypic divergence across species. PMID- 30298392 TI - Computational Prediction of De Novo Emerged Protein-Coding Genes. AB - De novo genes, that is, protein-coding genes originating from previously noncoding sequence, have gone from being considered impossibly unlikely to being recognized as an important source of genetic novelty in eukaryotic genomes. It is clear that de novo gene evolution is a rare but consistent feature of eukaryotic genomes, being detected in every genome studied. However, different studies often use different computational methods, and the numbers and identities of the detected genes vary greatly. Here we present a coherent protocol for the computational identification of de novo genes by comparative genomics. The method described uses homology searches, identification of syntenic regions, and ancestral sequence reconstruction to produce high-confidence candidates with robust evidence of de novo emergence. It is designed to be easily applicable given the basic knowledge of bioinformatic tools and scalable so that it can be applied on large and small datasets. PMID- 30298393 TI - Coevolutionary Signals and Structure-Based Models for the Prediction of Protein Native Conformations. AB - The analysis of coevolutionary signals from families of evolutionarily related sequences is a recent conceptual framework that provides valuable information about unique intramolecular interactions and, therefore, can assist in the elucidation of biomolecular conformations. It is based on the idea that compensatory mutations at specific residue positions in a sequence help preserve stability of protein architecture and function and leave a statistical signature related to residue-residue interactions in the 3D structure of the protein. Consequently, statistical analysis of these correlated mutations in subsets of protein sequence alignments can be used to predict which residue pairs should be in spatial proximity in the native functional protein fold. These predicted signals can be then used to guide molecular dynamics (MD) simulations to predict the three-dimensional coordinates of a functional amino acid chain. In this chapter, we introduce a general and efficient methodology to perform coevolutionary analysis on protein sequences and to use this information in combination with computational physical models to predict the native 3D conformation of functional polypeptides. We present a step-by-step methodology that includes the description and application of software tools and databases required to infer tertiary structures of a protein fold. The general pipeline includes instructions on (1) how to obtain direct amino acid couplings from protein sequences using direct coupling analysis (DCA), (2) how to incorporate such signals as interaction potentials in Calpha structure-based models (SBMs) to drive protein-folding MD simulations, (3) a procedure to estimate secondary structure and how to include such estimates in the topology files required in the MD simulations, and (4) how to build full atomic models based on the top Calpha candidates selected in the pipeline. The information presented in this chapter is self-contained and sufficient to allow a computational scientist to predict structures of proteins using publicly available algorithms and databases. PMID- 30298394 TI - Detecting Amino Acid Coevolution with Bayesian Graphical Models. AB - The comparative study of homologous proteins can provide abundant information about the functional and structural constraints on protein evolution. For example, an amino acid substitution that is deleterious may become permissive in the presence of another substitution at a second site of the protein. A popular approach for detecting coevolving residues is by looking for correlated substitution events on branches of the molecular phylogeny relating the protein coding sequences. Here we describe a machine learning method (Bayesian graphical models) implemented in the open-source phylogenetic software package HyPhy, http://hyphy.org , for extracting a network of coevolving residues from a sequence alignment. PMID- 30298395 TI - Context-Dependent Mutation Effects in Proteins. AB - Defining the extent of epistasis-the nonindependence of the effects of mutations is essential for understanding the relationship of genotype, phenotype, and fitness in biological systems. The applications cover many areas of biological research, including biochemistry, genomics, protein and systems engineering, medicine, and evolutionary biology. However, the quantitative definitions of epistasis vary among fields, and the analysis beyond just pairwise effects can be problematic. Here, we demonstrate the application of a particular mathematical formalism, the weighted Walsh-Hadamard transform, which unifies a number of different definitions of epistasis. We provide a computational implementation of such analysis using a computer-generated higher-order mutational dataset. We discuss general considerations regarding the null hypothesis for independent mutational effects, which then allows a quantitative identification of epistasis in an experimental dataset. PMID- 30298396 TI - High-Throughput Reconstruction of Ancestral Protein Sequence, Structure, and Molecular Function. AB - Ancestral protein sequence reconstruction is a powerful technique for explicitly testing hypotheses about the evolution of molecular function, allowing researchers to meticulously dissect how historical changes in protein sequence impacted functional repertoire by altering the protein's 3D structure. These techniques have provided concrete, experimentally validated insights into ancient evolutionary processes and help illuminate the complex relationship between protein sequence, structure, and function. Inferring the protein family phylogenies on which ancestral sequence reconstruction depends and reconstructing the sequences, themselves, are amenable to high-throughput computational analysis. However, determining the structures of ancestral-reconstructed proteins and characterizing their functions typically rely on time-consuming and expensive laboratory analyses, limiting most current studies to examining a relatively small number of specific hypotheses. For this reason, we have little detailed, unbiased information about how molecular function evolves across large protein family phylogenies. Here we describe a generalized protocol that integrates ancestral sequence reconstruction with structural homology modeling and structure based molecular affinity prediction to characterize historical changes in protein function across families with thousands of individual sequences. We highlight key steps in the analysis protocol requiring particularly careful attention to avoid introducing potential errors as well as steps for which computationally efficient subroutines can be substituted for more intensive approaches, allowing researchers to scale the analysis up or down, depending on available resources and requirements for reproducibility and scientific rigor. In our view, this approach provides a compelling compliment to more laboratory-intensive procedures, generating important contextual information that can help guide detailed experiments. PMID- 30298397 TI - Ancestral Sequence Reconstruction as a Tool for the Elucidation of a Stepwise Evolutionary Adaptation. AB - Ancestral sequence reconstruction (ASR) is a powerful tool to infer primordial sequences from contemporary, i.e., extant ones. An essential element of ASR is the computation of a phylogenetic tree whose leaves are the chosen extant sequences. Most often, the reconstructed sequence related to the root of this tree is of greatest interest: It represents the common ancestor (CA) of the sequences under study. If this sequence encodes a protein, one can "resurrect" the CA by means of gene synthesis technology and study biochemical properties of this extinct predecessor with the help of wet-lab experiments.However, ASR deduces also sequences for all internal nodes of the tree, and the well considered analysis of these "intermediates" can help to elucidate evolutionary processes. Moreover, one can identify key mutations that alter proteins or protein complexes and are responsible for the differing properties of extant proteins. As an illustrative example, we describe the protocol for the rapid identification of hotspots determining the binding of the two subunits within the heteromeric complex imidazole glycerol phosphate synthase. PMID- 30298398 TI - Enhancing Statistical Multiple Sequence Alignment and Tree Inference Using Structural Information. AB - For highly divergent sequences, there is often insufficient information to reliably construct alignments and phylogenetic trees. Since protein structure may be strongly conserved despite large divergences in sequence, structural information can be used to help identify homology in such cases.While there exist well-studied models of sequence evolution, structurally informed alignment methods have typically made use of geometric measures of deviation that do not take into account the underlying mutational processes. In order to integrate structural information into sequence-based evolutionary models, we recently developed a stochastic model of structural evolution on a phylogenetic tree and implemented this as the StructAlign plugin for the StatAlign statistical alignment package.In this chapter, we will outline the types of analyses that can be carried out using StructAlign, illustrating how the inclusion of structural information can be used to inform joint estimation of alignments and trees. StructAlign can also be used to infer branch-specific rates of structural evolution, and analysis of an example globin dataset highlights strong variation in the inferred rate across the tree. While structure is more highly conserved within clades, the rate of structural divergence as a function of sequence variation is larger between functionally divergent proteins. Allowing for the rate of structural divergence to vary over the tree results in an improved fit to the empirically observed pairwise RMSD values. PMID- 30298399 TI - The Influence of Protein Stability on Sequence Evolution: Applications to Phylogenetic Inference. AB - Phylogenetic inference from protein data is traditionally based on empirical substitution models of evolution that assume that protein sites evolve independently of each other and under the same substitution process. However, it is well known that the structural properties of a protein site in the native state affect its evolution, in particular the sequence entropy and the substitution rate. Starting from the seminal proposal by Halpern and Bruno, where structural properties are incorporated in the evolutionary model through site specific amino acid frequencies, several models have been developed to tackle the influence of protein structure on sequence evolution. Here we describe stability constrained substitution (SCS) models that explicitly consider the stability of the native state against both unfolded and misfolded states. One of them, the mean-field model, provides an independent sites approximation that can be readily incorporated in maximum likelihood methods of phylogenetic inference, including ancestral sequence reconstruction. Next, we describe its validation with simulated and real proteins and its limitations and advantages with respect to empirical models that lack site specificity. We finally provide guidelines and recommendations to analyze protein data accounting for stability constraints, including computer simulations and inferences of protein evolution based on maximum likelihood. Some practical examples are included to illustrate these procedures. PMID- 30298400 TI - Navigating Among Known Structures in Protein Space. AB - Present-day protein space is the result of 3.7 billion years of evolution, constrained by the underlying physicochemical qualities of the proteins. It is difficult to differentiate between evolutionary traces and effects of physicochemical constraints. Nonetheless, as a rule of thumb, instances of structural reuse, or focusing on structural similarity, are likely attributable to physicochemical constraints, whereas sequence reuse, or focusing on sequence similarity, may be more indicative of evolutionary relationships. Both types of relationships have been studied and can provide meaningful insights to protein biophysics and evolution, which in turn can lead to better algorithms for protein search, annotation, and maybe even design.In broad strokes, studies of protein space vary in the entities they represent, the similarity measure comparing these entities, and the representation used. The entities can be, for example, protein chains, domains, supra-domains, or smaller protein sub-parts denoted themes. The measures of similarity between the entities can be based on sequence, structure, function, or any combination of these. The representation can be global, encompassing the whole space, or local, focusing on a particular region surrounding protein(s) of interest. Global representations include lists of grouped proteins, protein networks, and maps. Networks are the abstraction that is derived most directly from the similarity data: each node is the protein entity (e.g., a domain), and edges connect similar domains. Selecting the entities, the similarity measure, and the abstraction are three intertwined decisions: the similarity measures allow us to identify the entities, and the selection of entities influences what is a meaningful similarity measure. Similarly, we seek entities that are related to each other in a way, for which a simple representation describes their relationships succinctly and accurately. This chapter will cover studies that rely on different entities, similarity measures, and a range of representations to better understand protein structure space. Scholars may use publicly available navigators offering a global representation, and in particular the hierarchical classifications SCOP, CATH, and ECOD, or a local representation, which encompass structural alignment algorithms. Alternatively, scholars can configure their own navigator using existing tools. To demonstrate this DIY (do it yourself) approach for navigating in protein space, we investigate substrate-binding proteins. By presenting sequence similarities among this large and diverse protein family as a network, we can infer that one member (pdb ID 4ntl; of yet unknown function) may bind methionine and suggest a putative binding mechanism. PMID- 30298401 TI - A Graph-Based Approach for Detecting Sequence Homology in Highly Diverged Repeat Protein Families. AB - Reconstructing evolutionary relationships in repeat proteins is notoriously difficult due to the high degree of sequence divergence that typically occurs between duplicated repeats. This is complicated further by the fact that proteins with a large number of similar repeats are more likely to produce significant local sequence alignments than proteins with fewer copies of the repeat motif. Furthermore, biologically correct sequence alignments are sometimes impossible to achieve in cases where insertion or translocation events disrupt the order of repeats in one of the sequences being aligned. Combined, these attributes make traditional phylogenetic methods for studying protein families unreliable for repeat proteins, due to the dependence of such methods on accurate sequence alignment.We present here a practical solution to this problem, making use of graph clustering combined with the open-source software package HH-suite, which enables highly sensitive detection of sequence relationships. Carrying out multiple rounds of homology searches via alignment of profile hidden Markov models, large sets of related proteins are generated. By representing the relationships between proteins in these sets as graphs, subsequent clustering with the Markov cluster algorithm enables robust detection of repeat protein subfamilies. PMID- 30298402 TI - Exploring Enzyme Evolution from Changes in Sequence, Structure, and Function. AB - The goal of our research is to increase our understanding of how biology works at the molecular level, with a particular focus on how enzymes evolve their functions through adaptations to generate new specificities and mechanisms. FunTree (Sillitoe and Furnham, Nucleic Acids Res 44:D317-D323, 2016) is a resource that brings together sequence, structure, phylogenetic, and chemical and mechanistic information for 2340 CATH superfamilies (Sillitoe et al., Nucleic Acids Res 43:D376-D381, 2015) (which all contain at least one enzyme) to allow evolution to be investigated within a structurally defined superfamily.We will give an overview of FunTree's use of sequence and structural alignments to cluster proteins within a superfamily into structurally similar groups (SSGs) and generate phylogenetic trees augmented by ancestral character estimations (ACE). This core information is supplemented with new measures of functional similarity (Rahman et al., Nat Methods 11:171-174, 2014) to compare enzyme reactions based on overall bond changes, reaction centers (the local environment atoms involved in the reaction), and the structural similarities of the metabolites involved in the reaction. These trees are also decorated with taxonomic and Enzyme Commission (EC) code and GO annotations, forming the basis of a comprehensive web interface that can be found at http://www.funtree.info . In this chapter, we will discuss the various analyses and supporting computational tools in more detail, describing the steps required to extract information. PMID- 30298403 TI - Identification of Protein Homologs and Domain Boundaries by Iterative Sequence Alignment. AB - Evolutionary domains are protein regions with observable sequence similarity to other known domains. Here we describe how to use common sequence and profile alignment algorithms (i.e., BLAST, HHsearch) to delineate putative domains in novel protein sequences, given a reference library of protein domains. In this case, we use our database of evolutionary domains (ECOD) as a reference, but other domain sequence libraries could be used (e.g., SCOP, CATH). We describe our domain partition algorithm along with specific notes on how to avoid domain indexing errors when working with multiple data sources and software algorithms with differing outputs. PMID- 30298404 TI - A Roadmap to Domain Based Proteomics. AB - Protein domains are reusable segments of proteins and play an important role in protein evolution. By combining the elements from a relatively small set of domains into unique arrangements, a large number of distinct proteins can be generated. Since domains often have specific functions, changes in their arrangement usually affect the overall protein function. Furthermore, domains are well amenable to computational representations, e.g., by Hidden Markov Models (HMMs), and these HMMs are widely represented in various databases. Therefore, domains can be efficiently used for proteomic analyses. Here, we describe how domains are annotated using different domain databases and then how to assess the annotation quality of proteomes. We next show how functional annotations of domains in large-scale data such as whole genomes or transcriptomes can be used to analyze molecular differences between species. Furthermore, we describe methods to analyze the changes in domain content of proteins which significantly helps to characterize and reconstruct the modular evolution of proteins. Altogether, domain-based methods offer a computationally highly effective approach to analyze large amounts of proteomic data in an evolutionary setting. PMID- 30298405 TI - Modeling of Protein Tertiary and Quaternary Structures Based on Evolutionary Information. AB - Proteins are subject to evolutionary forces that shape their three-dimensional structure to meet specific functional demands. The knowledge of the structure of a protein is therefore instrumental to gain information about the molecular basis of its function. However, experimental structure determination is inherently time consuming and expensive, making it impossible to follow the explosion of sequence data deriving from genome-scale projects. As a consequence, computational structural modeling techniques have received much attention and established themselves as a valuable complement to experimental structural biology efforts. Among these, comparative modeling remains the method of choice to model the three dimensional structure of a protein when homology to a protein of known structure can be detected.The general strategy consists of using experimentally determined structures of proteins as templates for the generation of three-dimensional models of related family members (targets) of which the structure is unknown. This chapter provides a description of the individual steps needed to obtain a comparative model using SWISS-MODEL, one of the most widely used automated servers for protein structure homology modeling. PMID- 30298407 TI - Predicting Functions of Disordered Proteins with MoRFpred. AB - Intrinsically disordered proteins and regions are involved in a wide range of cellular functions, and they often facilitate protein-protein interactions. Molecular recognition features (MoRFs) are segments of intrinsically disordered regions that bind to partner proteins, where binding is concomitant with a transition to a structured conformation. MoRFs facilitate translation, transport, signaling, and regulatory processes and are found across all domains of life. A popular computational tool, MoRFpred, accurately predicts MoRFs in protein sequences. MoRFpred is implemented as a user-friendly web server that is freely available at http://biomine.cs.vcu.edu/servers/MoRFpred/ . We describe this predictor, explain how to run the web server, and show how to interpret the results it generates. We also demonstrate the utility of this web server based on two case studies, focusing on the relevance of evolutionary conservation of MoRF regions. PMID- 30298406 TI - Interface-Based Structural Prediction of Novel Host-Pathogen Interactions. AB - About 20% of the cancer incidences worldwide have been estimated to be associated with infections. However, the molecular mechanisms of exactly how they contribute to host tumorigenesis are still unknown. To evade host defense, pathogens hijack host proteins at different levels: sequence, structure, motif, and binding surface, i.e., interface. Interface similarity allows pathogen proteins to compete with host counterparts to bind to a target protein, rewire physiological signaling, and result in persistent infections, as well as cancer. Identification of host-pathogen interactions (HPIs)-along with their structural details at atomic resolution-may provide mechanistic insight into pathogen-driven cancers and innovate therapeutic intervention. HPI data including structural details is scarce and large-scale experimental detection is challenging. Therefore, there is an urgent and mounting need for efficient and robust computational approaches to predict HPIs and their complex (bound) structures. In this chapter, we review the first and currently only interface-based computational approach to identify novel HPIs. The concept of interface mimicry promises to identify more HPIs than complete sequence or structural similarity. We illustrate this concept with a case study on Kaposi's sarcoma herpesvirus (KSHV) to elucidate how it subverts host immunity and helps contribute to malignant transformation of the host cells. PMID- 30298408 TI - Exploring Protein Conformational Diversity. AB - The native state of proteins is composed of conformers in dynamical equilibrium. In this chapter, different issues related to conformational diversity are explored using a curated and experimentally based database called CoDNaS (Conformational Diversity in the Native State). This database is a collection of redundant structures for the same sequence. CoDNaS estimates the degree of conformational diversity using different global and local structural similarity measures. It allows the user to explore how structural differences among conformers change as a function of several structural features providing further biological information. This chapter explores the measurement of conformational diversity and its relationship with sequence divergence. Also, it discusses how proteins with high conformational diversity could affect homology modeling techniques. PMID- 30298409 TI - High-Throughput Antibody Structure Modeling and Design Using ABodyBuilder. AB - Antibodies are proteins of the adaptive immune system; they can be designed to bind almost any molecule, and are increasingly being used as biotherapeutics. Experimental antibody design is an expensive and time-consuming process, and computational antibody design methods can now be used to help develop new therapeutics and diagnostics. Within the design pipeline, accurate antibody structure modeling is essential, as it provides the basis for antibody-antigen docking, binding affinity prediction, and estimating thermal stability. Ideally, models should be rapidly generated, allowing the exploration of the breadth of antibody space. This allows methods to replicate the natural processes of antibody diversification (e.g., V(D)J recombination and somatic hypermutation), and cope with large volumes of data that are typical of next-generation sequencing datasets. Here we describe ABodyBuilder and PEARS, algorithms that build and mutate antibody model structures. These methods take ~30 s to generate a model antibody structure. PMID- 30298410 TI - In Silico-Directed Evolution Using CADEE. AB - Recent years have seen an explosion of interest in both sequence- and structure based approaches toward in silico-directed evolution. We recently developed a novel computational toolkit, CADEE, which facilitates the computer-aided directed evolution of enzymes. Our initial work (Amrein et al., IUCrJ 4:50-64, 2017) presented a pedagogical example of the application of CADEE to triosephosphate isomerase, to illustrate the CADEE workflow. In this contribution, we describe this workflow in detail, including code input/output snippets, in order to allow users to set up and execute CADEE simulations on any system of interest. PMID- 30298411 TI - Open-label placebo reduces fatigue in cancer survivors: a randomized trial. AB - PURPOSE: Cancer-related fatigue (CRF) is a common and challenging late effect for many cancer survivors. Clinical trials demonstrate robust placebo effects on CRF in blinded trials. Recently, open-label placebo (OLP) has been shown to improve a variety of symptoms in other populations. We conducted a randomized controlled trial to investigate the effect of OLP on CRF in cancer survivors, and to explore biologic and psychological correlates of placebo efficacy. METHODS: Forty cancer survivors (92.5% female; mean age 47.3 years) were randomized to OLP or no treatment control. OLP participants were prescribed two placebo tablets twice daily, for 3 weeks. All participants completed assessments at Baseline, Day 8, and Day 22. The primary endpoint was change in CRF (FACIT-F), and secondary outcomes included exercise frequency, mood, and quality of life. We examined whether personality characteristics or a genetic variation important in dopamine catabolism (catechol-O-methyltransferase; COMT) affected the placebo response. RESULTS: The OLP group reported significantly improved CRF at both Day 8 (p = 0.005) and Day 22 (p = .02), while the control group did not (ps > .05). CRF improvement differed by COMT genotype, but was not associated with personality characteristics. Marginal improvements were noted in the placebo group for some secondary outcomes (exercise frequency and quality of life), but not in the control group. CONCLUSIONS: Results demonstrate that even when administered openly, placebos improve CRF in cancer survivors and dopaminergic systems may be associated with this response. This novel research has meaningful implications for the use of OLP in symptom management for cancer survivors. PMID- 30298412 TI - Short- vs long-course antibiotic therapy for pneumonia: a comparison of systematic reviews and guidelines for the SIMI Choosing Wisely Campaign. AB - Reduction of the inappropriate use of antibiotics in clinical practice is one of the main goals of the Societa Italiana di Medicina Interna (SIMI) choosing wisely campaign. We conducted a systematic review of secondary studies (systematic reviews and guidelines) to verify what evidence is available on the duration of antibiotic treatment in Pneumonia. A literature systematic search was performed to identify all systematic reviews and the three most cited and recent guidelines that address the duration of antibiotic therapy in pneumonia. Moreover, a meta analysis of non-duplicate data from randomized controlled trials (RCTs) considered in the enrolled systematic reviews was performed together with a trial sequential analysis to identify the need for further studies. Two systematic reviews on antibiotic duration in community-acquired pneumonia (CAP) for a total of 17 RCTs (2764 patients) were enrolled in our study. Meta-analysis of non duplicate RCTs show a non-significant difference in rate of treatment failure between short (<= 7 days) and long (> 7 days) antibiotic treatment course: RR 1.05 (95% CI, 0.82-1.36). The trial sequential analysis suggests that further data would not affect current evidence or become clinically relevant. Selected guidelines suggest consideration of a short course, with a low grade of evidence and without citing the already published systematic reviews. Antibiotic treatment of CAP for <= 7 days is not associated with a higher rate of treatment failure than longer courses and should thus be taken in consideration. Guidelines should upgrade the evidence on this topic. PMID- 30298413 TI - The discrepancy between patient expectations and actual outcome reduces at the first 6 months following total knee replacement surgery. AB - PURPOSE: Patients undergoing total knee arthroplasty often have unfulfilled expectations from the surgery that can lead to dissatisfaction. This study aimed to examine the discrepancy between patients' expectations and actual functional abilities prior to undergoing knee replacement surgery, and at 6 and 12 months following the surgery. METHODS: A survey was undertaken of patients before, and 6 and 12 months post-surgery. The survey included the Knee Surgery Perception Questionnaire (KSPQ) to assess patients' current perception of their level of function and pain, their desired outcomes, and the discrepancy between the two. Pain, function and quality of life were also assessed. Repeated measure ANOVAs were used to assess differences between pre- and post-surgery. RESULTS: A total of 176 patients were surveyed. Significant differences in the KSPQ discrepancy scores (subscale and total scores) were demonstrated between the three assessment point times (p < 0.01). Paired t tests identified significant differences between the pre-surgery and 6-month KSPQ discrepancy scores, (p < 0.01) indicative of substantial improvement in physical function and slight reduction in expectations. Overall significant improvement (p < 0.01) was reported over time across all measures: physical function, pain and stiffness and quality of life. CONCLUSION: The discrepancy between patients' current abilities and their expectation changes following surgery, especially in the first 6 months post surgery. Patients' goals might change as their function and pain improve post surgery. Combining education programmes and discussion with the treating orthopaedic surgeons pre-operatively is important for the development of realistic, achievable expectations. LEVEL OF EVIDENCE: III. PMID- 30298414 TI - Improved results of ACL primary repair in one-part tears with intact synovial coverage. AB - PURPOSE: It was the aim to assess the influence of synovial sheath disruption on early failure of primary anterior cruciate ligament (ACL) repair. It was hypothesized that more-part ACL tears with disruption of the synovial sheath are associated with a higher risk of failure after primary ACL repair. METHODS: A cohort study was conducted comprising patients with primal ACL tears undergoing primary ACL repair and dynamic intraligamentary stabilization (DIS). The patients were stratified into three groups: A-one-part rupture with intact synovial membrane (n = 50), B-two-part ruptures resultant to separation of the ACL into two main bundles with synovial membrane tearing (n = 52) and C-more parts involving multilacerated ruptures with membrane disruption (n = 22). Failure was defined as a retear or residual laxity (anterior posterior translation > 5 mm compared to healthy knee). Adjustment for potential risk factors was performed using a multivariate logistic-regression model. RESULTS: The overall failure rate was 17.7% throughout the mean follow-up period of 2.3 +/- 0.8 years. The failure rate in patients with one-part ACL tears with an intact synovial membrane was 4% (n = 2) (Group A), which was significantly lower than the failure rates in groups B and C, 26.9% (n = 14) (p = 0.001) and 27.3% (n = 6) (p = 0.003), respectively. Disruption of the synovial sheath in two- or more-part tears was identified as an independent factor influencing treatment failure in primary ACL repair (OR 8.9; 95% CI 2.0-40.0). CONCLUSION: The integrity of the ACL bundles and synovial sheath is a factor that influences the success of ACL repair. This needs to be considered intra-operatively when deciding about repair. LEVEL OF EVIDENCE: IV. PMID- 30298415 TI - High risk of tunnel convergence during combined anterior cruciate ligament and anterolateral ligament reconstruction. AB - PURPOSE: To assess the risk of femoral tunnel convergence in combined anterior cruciate ligament (ACL) and anterolateral ligament (ALL) reconstructions. The hypothesis was that a more proximal and anterior orientation of the ALL femoral tunnel should reduce the risk of convergence with the ACL femoral tunnel. METHODS: 15 fresh-frozen cadaver knees were examined. An anatomic ACL femoral tunnel was drilled arthroscopically in each specimen and ALL tunnels were made in two directions: (1) 0 degrees coronal angulation and 20 degrees axial angulation, (2) 30 degrees coronal angulation and 30 degrees axial angulation. Computed tomography scans were performed to investigate tunnel convergence and to measure the minimal distance between tunnels, tunnel length and the LFC width. RESULTS: Tunnel convergence occurred in 20 of 30 cases (67%). Convergence was significantly reduced when tunnels were drilled at 30 degrees coronal and 30 degrees axial angulation (p < 0.05). The mean length of the ALL tunnel was 15.9 mm [95% CI (13.6; 18.1)] and was independent of ALL tunnel angulation. The mean minimal distance between the ALL and ACL tunnel was 3.1 mm [95% CI (2.1; 4.1)]. The odds ratio for tunnel convergence was 3.5 for small LFC, relative to large LFC (n.s.) CONCLUSION: A high risk of tunnel convergence was observed when performing combined ACL and ALL reconstructions. The clinical relevance of this work is that the occurrence of tunnel conflicts can be reduced by aiming the ALL tunnel in a more proximal and anterior direction. Surgeons should be aware of this, since tunnel convergence could jeopardize the ACL reconstruction and fixation. PMID- 30298417 TI - Effect of Perioperative High Oxygen Concentration on Postoperative SSI in Elective Colorectal Surgery-A Randomized Controlled Trial. AB - BACKGROUND: This study was carried out to investigate the effect of perioperative high oxygen concentration on surgical site infection (SSI) in patients undergoing elective colorectal surgery. METHODS: This was a single-center, prospective, parallel arm, double-blind, superiority randomized controlled trial. All patients more than 18 years of age undergoing elective colorectal surgery were included as per the inclusion criteria. Patients were randomized at the time of induction of anesthesia into high concentration and standard concentration oxygen group based on the concentration of oxygen. Incidence of SSI, day of the detection of SSI, grade of SSI, incidence of anastomotic leak, postoperative day of return of bowel functions, day of starting oral feeds, day of ambulation, and length of hospitalization were studied in both the groups. RESULTS: A total of 94 patients were included in the study, 47 patients each in high concentration oxygen group and standard concentration oxygen group respectively. The SSI rates were comparable between the two groups [55.3% (95% CI-4.012-69.83) vs. 40.4% (95% CI 26.37-55.73); p = 0.215]. There was no significant difference found with respect to mean day of detection of SSI [4.5(IQR-3.0-7.5) vs. 6.0 (IQR-3.0-9.0; p = 0.602], postoperative day of return of bowel functions (2.20 +/- 0.542 vs. 2.13 +/- 0.582; p = 0.540), oral feeds (3.62 +/- 0.945 vs. 3.46 +/- 1.048; p = 0.544), ambulation (4.17 +/- 0.868 vs. 4.17 +/- 1.270; p = 0.987), and the length of hospitalization [15(IQR-10-19) vs. 15(IQR-10.75-18.25); p = 0.862] between the two groups. CONCLUSION: There was no significant difference in the rate of SSI with the use of perioperative high oxygen concentration in patients undergoing elective colorectal surgery. PMID- 30298416 TI - A Novel Strategy of Laparoscopic Insufflation Rate Improving Shoulder Pain: Prospective Randomized Study. AB - BACKGROUND: Laparoscopic surgery is the main trend method in a variety of surgical fields. Post-operative shoulder pain remains a bothersome issue although many surgical techniques have been applied to minimize it. A simple novel approach to reduce shoulder pain without adverse effects during and after laparoscopic surgery is desired. METHODS: This prospective randomized controlled study was conducted to enroll a total of 140 patients to evaluate the efficacy of low flow rate (1 L/min) for induction followed by high flow rate (10 L/min) for maintaining 12 mmHg pneumoperitoneum (group A, n = 70) during laparoscopic cholecystectomy (LC), compared to the continuous high flow rate group (group B, n = 70) in postoperative shoulder pain and other clinical features. The 10-visual analog scale (VAS) was applied for the severity of shoulder pain and scores were obtained at 1, 6, 12, 24, and 48 h after LC. RESULTS: There was no obvious difference in baseline characteristics as well as operative time, occurrence of bradycardia, or hospital stay between groups. The incidence of shoulder pain was not significantly different (group A 45.7% vs group B 48.6%, p = 0.866). However, the patients in group A with shoulder pain reported significantly less pain scores (p < 0.001) at 12 and 24 h after surgery, compared with those in group B. CONCLUSIONS: Applying the strategy of low flow rate to induce pneumoperitoneum followed by high flow rate to maintain the pressure provides advantages to reduce the severity of shoulder pain for patients who underwent LC and then experienced shoulder pain. PMID- 30298418 TI - Comparison of Long-term Quality of Life in Patients with Esophageal Cancer after Ivor-Lewis, Mckeown, or Sweet Esophagectomy. AB - BACKGROUND: The aim of this study was to compare the long-term quality of life (QoL) in patients after Sweet, Ivor-Lewis, or Mckeown esophagectomy. METHODS: Esophageal cancer patients after Sweet, Ivor-Lewis, or Mckeown esophagectomy from 2010 to 2012 were included. QoL was assessed according to the European Organization for Research and Treatment of Cancer general questionnaire: QLQ-C30 and esophagus-specific questionnaire: QLQ-OES18. RESULTS: A total of 126 qualified patients who have been alive for more than 3 years without tumor recurrence were divided into three groups: the Sweet group (n = 40), Ivor-Lewis group (n = 38), and Mckeown group (n = 48). Among these three groups, the QLQ-C30 mean scores of global health status, functional and symptom scales, and general QoL were similar. The symptom scales of QLQ-OSE18 showed that patients who had a Mckeown operation experienced more problem of eating (P = 0.029), choking when swallowing (P = 0.010) and coughing (P = 0.016), while patients undergoing Sweet operation complained more symptom of reflux (P = 0.003) and pain (P = 0.000). CONCLUSIONS: All three types of esophagectomy provided a generally good long-term QoL. However, patients in Sweet and Mckeown group tend to suffer from a higher symptomatic burden as compared to Ivor-Lewis approach. PMID- 30298419 TI - Post-Discharge Opioid Prescribing Patterns and Risk Factors in Patients Undergoing Elective Colon and Rectal Surgery Without Complications. AB - BACKGROUND: Few studies have examined opioid usage in the post-discharge period. The primary aim of this study was to evaluate the need for post-discharge opioids in a unique set of patients: those undergoing colorectal operations and experiencing no surgical complications. The secondary aim was to examine the accuracy of the Opioid Risk Tool (ORT) to predict the need for additional opioid prescriptions. Our hypotheses were that few patients would require post-discharge opioids and that the ORT would predict patients requiring post-discharge opioids. METHODS: All patients undergoing elective colorectal surgery between January 2012 and December 2014 that did not experience NSQIP complications within 30 days or receive an opioid prescription in the 2 weeks prior to operation were reviewed. ORT score was calculated for all patients. Patients requiring post-discharge opioids within 1 year were compared to those not receiving additional opioids after discharge. RESULTS: There were 367 patients that met inclusion criteria and 56 (15%) received post-discharge opioids. Opioid use in the year prior to surgery was the only significant risk factor to receive post-discharge opioids. Opioids were prescribed for three distinct reasons by three groups of prescribers. The ORT did not accurately predict need for post-discharge opioids. CONCLUSIONS: Even among patients without complications, 15% received post-discharge opioid prescriptions. Previous opioid use within the year prior to surgery was a major risk factor for additional prescriptions. The timing and prescriber's specialty are impacted by the indication for post-discharge opioids. The ORT did not predict which patients would receive post-discharge opioids. PMID- 30298421 TI - Primary Sarcomatoid Malignant Mesothelioma of the Pancreas. PMID- 30298420 TI - Slow Gait Speed Is a Risk Factor for Complications After Hepatic Resection. AB - PURPOSE: The aims of this study were to clarify the relationship of gait speed, hand grip strength, and skeletal muscle mass with complications after hepatic resection and to identify risk factors for complications in patients who underwent hepatic resection. METHODS: We evaluated the risk factors for complications after hepatic resection in 154 consecutive patients. Preoperative factors included gait speed, hand grip strength, and skeletal muscle mass. The gait speed and hand grip strength of patients were measured by physical therapists, and skeletal muscle mass was measured by computed tomography. Multivariate logistic regression analyses using preoperative factors were performed to assess predictors of the development of complications after hepatic resection. RESULTS: Thirty-three patients (21.4%) developed complications after hepatic resection. These patients had a significantly lower serum albumin level (p = 0.015), slower gait speed (p = 0.007), higher rate of hepatic resection >= 2 Couinaud segments (p = 0.014), and lower rate of laparoscopic hepatic resection (p = 0.017) than patients without complications. Multivariate analysis revealed that a gait speed <= 1.10 m/s and a serum albumin level of <= 4.0 g/dl were independent risk factors for complications after hepatic resection. CONCLUSIONS: Slow gait speed and low serum albumin level are significant risk factors for complications after hepatic resection. These data will be helpful for perioperative patient management. PMID- 30298422 TI - Use of Activity Tracking in Major Visceral Surgery-the Enhanced Perioperative Mobilization Trial: a Randomized Controlled Trial. AB - BACKGROUND: Early mobilization is one essential item within the enhanced recovery after surgery (ERAS) concept, but lacks solid evidence and a standardized assessment. The aim was to monitor and increase the postoperative mobilization of patients after major visceral surgery by providing a continuous step count feedback using activity tracking wristbands. METHODS: The study was designed as a randomized controlled single-center trial (NCT02834338) with two arms (open and laparoscopic surgery). Participants were randomized to either receive feedback of their step counts using an activity tracker wristband or not. The primary study endpoint was the mean step count during the first 5 postoperative days (PODs). RESULTS: A total of 132 patients were randomized. After laparoscopic operations, the average step count during PODs 1-5 was significantly increased by the feedback compared with the control group (P < 0.001); the cumulative step count (9867 versus 6103, P = 0.037) and activity time were also significantly increased. These results could not be confirmed in the open surgery arm. Possible reasons were a higher age and significantly more comorbidities in the open intervention group. Patients who achieved more than the median cumulative step count had a significantly shorter hospital stay and lower morbidity in both arms. The average step count also correlated with the length of hospital stay (R = - 0.341, P < 0.001). CONCLUSION: This study is the first randomized controlled trial investigating the use and feasibility of activity tracking to monitor and enhance postoperative mobilization in abdominal surgery. Our results demonstrate that activity tracking can enhance perioperative mobilization after laparoscopic surgery. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02834338. PMID- 30298423 TI - A new NBIA patient from Turkey with homozygous C19ORF12 mutation. PMID- 30298424 TI - Apolipoproteins A1, B, and apoB/apoA1 ratio are associated with first ST-segment elevation myocardial infarction but not with recurrent events during long-term follow-up. AB - INTRODUCTION: The current way to assess the risk of cardiovascular disease (CVD) is to measure conventional lipid and lipoprotein cholesterol fractions. Despite the success of statin treatment, residual cardiovascular risk remains high. Therefore, the value of extensive serum apolipoprotein (apo) profiling to assess the risk of ST-segment elevation myocardial infarction (STEMI) and of major adverse cardiac events (MACE) in patients with STEMI was investigated in a case control design. METHODS AND RESULTS: Serum apo levels were measured using liquid chromatography and mass spectrometry in 299 healthy individuals and 220 patients with STEMI. First, the association of apo profiles in baseline samples with risk of STEMI was examined, and second, the association of apo profiles at baseline with risk of recurrent MACE in patients with STEMI in a longitudinal study design was studied. High baseline (> 1.25 g/L) apoA1 levels were associated with a decreased risk of STEMI [odds ratio (OR) 0.17; 95% CI 0.11-0.26], whereas high apoB (> 1.00 g/L) levels (OR 2.17; 95% CI 1.40-3.36) and apoB/apoA1 ratio (OR per 1 SD (OR/SD): 2.16; 95% CI 1.76-2.65) were associated with an increased risk. Very-low-density-lipoprotein (VLDL)-associated apos gave conflicting results. Neither conventional lipid levels nor apo levels were associated with MACE in the STEMI group. CONCLUSION: In conclusion, apoA1, apoB, and apoB/apoA1 were strongly associated with risk of STEMI. No clear relation between VLDL-associated apos and the risk of STEMI was found. Neither baseline serum apos nor lipids predicted MACE in statin-treated patients during long-term follow-up after a first STEMI. PMID- 30298425 TI - Alterations in structural rich-club connectivity of the precuneus are associated with depressive symptoms among individuals with subjective memory complaints. AB - The association between subjective memory complaints (SMCs) and depressive symptoms has been widely reported and both have been regarded as risk factors for dementia, such as Alzheimer's disease (AD). Although SMCs arise as early as in middle age, the exact neural correlates of comorbid depressive symptoms among individuals who are middle-aged and with SMCs have not yet been well investigated. Because rich-club organization of the brain plays a key role in the pathophysiology of various neuropsychiatric disorders, the investigation of rich club organization may provide insight regarding the neurobiological mechanisms of depressive symptoms in SMCs. In the current study, we compared the rich-club organization in the structural brain connectivity between individuals who have SMCs along with depressive symptoms (SMCD) and individuals with SMCs but without depressive symptoms (SMCO). A total of 53 individuals with SMCD and 91 individuals with SMCO participated in the study. For all participants, high resolution, T1-weighted images and diffusion tensor images were obtained, and the network analysis was performed. Individuals with SMCD had lower connectivity strength between the precuneus and other rich-club nodes than those with SMCO, which was significant after adjusting for potential confounders. Our findings suggest that disruptions of rich-club connectivity strength of the precuenus are associated with depressive symptoms in middle-aged individuals with SMCs. Given that the precuneus is one of the commonly affected regions in the early stages of AD, our findings may imply that the concomitant depressive symptoms in middle aged individuals with SMCs could reflect structural alterations related to AD.

PMID- 30298427 TI - Frond transformation system mediated by Agrobacterium tumefaciens for Lemna minor. AB - The Lemnaceae, known as duckweed, the smallest flowering aquatic plant, shows promise as a plant bioreactor. For applying this potential plant bioreactor, establishing a stable and efficient genetic transformation system is necessary. The currently favored callus-based method for duckweed transformation is time consuming and genotype limited, as it requires callus culture and regeneration, which is inapplicable to many elite duckweed strains suitable for bioreactor exploitation. In this study, we attempted to establish a simple frond transformation system mediated by Agrobacterium tumefaciens for Lemna minor, one of the most widespread duckweed species in the world. To evaluate the feasibility of the new transformation system, the gene CYP710A11 was overexpressed to improve the yield of stigmasterol, which has multiple medicinal purposes. Three L. minor strains, ZH0055, D0158 and M0165, were transformed by both a conventional callus transformation system (CTS) and the simple frond transformation system (FTS). GUS staining, PCR, quantitative PCR and stigmasterol content detection showed that FTS can produce stable transgenic lines as well as CTS. Moreover, compared to CTS, FTS can avoid the genotype constraints of callus induction, thus saving at least half of the required processing time (CTS took 8-9 months while FTS took approximately 3 months in this study). Therefore, this transformation system is feasible in producing stable transgenic lines for a wide range of L. minor genotypes. PMID- 30298428 TI - Comparative analysis of selection mode reveals different evolutionary rate and expression pattern in Arachis duranensis and Arachis ipaensis duplicated genes. AB - KEY MESSAGE: Our results reveal that Ks is a determining factor affecting selective pressure and different evolution and expression patterns are detected between PSGs and NSGs in wild Arachis duplicates. Selective pressure, including purifying (negative) and positive selection, can be detected in organisms. However, studies on comparative evolutionary rates, gene expression patterns and gene features between negatively selected genes (NSGs) and positively selected genes (PSGs) are lagging in paralogs of plants. Arachis duranensis and Arachis ipaensis are ancestors of the cultivated peanut, an important oil and protein crop. Here, we carried out a series of systematic analyses, comparing NSG and PSG in paralogs, using genome sequences and transcriptome datasets in A. duranensis and A. ipaensis. We found that synonymous substitution rate (Ks) is a determining factor affecting selective pressure in A. duranensis and A. ipaensis duplicated genes. Lower expression level, lower gene expression breadth, higher codon bias and shorter polypeptide length were found in PSGs and not in NSGs. The correlation analyses showed that gene expression breadth was positively correlated with polypeptide length and GC content at the first codon site (GC1) in PSGs and NSGs, respectively. There was a negative correlation between expression level and polypeptide length in PSGs. In NSGs, the Ks was positively correlated with expression level, gene expression breadth, GC1, and GC content at the third codon site (GC3), but selective pressure was negatively correlated with expression level, gene expression breadth, polypeptide length, GC1, and GC3 content. The function of most duplicated gene pairs was divergent under drought and nematode stress. Taken together, our results show that different evolution and expression patterns occur between PSGs and NSGs in paralogs of two wild Arachis species. PMID- 30298430 TI - Normal pancreatic volume in adults is influenced by visceral fat, vertebral body width and age. AB - OBJECTIVES: The aim was to describe the pancreatic volume (PV) in a cohort of subjects with no prior history of pancreatic disease, and to explore the relationship between PV and conventional two-point measurements of the pancreas. Associations between PV, gender, age, abdominal body composition, and human height were explored as well. METHODS: CT scans from 204 trauma patients (20-80 years, 100 males) were evaluated. PV was measured with semi-automatic segmentation. Standardized two-point measurements of the pancreas were obtained together with L1 vertebral body size (a proxy for human height) and abdominal body composition. Associations between PV and the other parameters were explored using uni- and multivariate linear regression. RESULTS: The mean PV was 77.9 +/- 21.7(SD) cm3 with an interindividual variability from 18.8 to 139.8 cm3. The transversal diameter of the pancreatic head showed the strongest correlation to PV (r = 0.500, p < 0.001). Age, width of the L1 vertebral body, and visceral fat cross-sectional area were all independently associated with PV (all p < 0.001), while no independent association was seen for gender (p = 0.441). CONCLUSIONS: The pancreatic volume is subject to a large interindividual variability and is associated with age, human height and body composition, while gender had no independent influence on the pancreatic volume. Thus, future studies using PV as an outcome parameter should be evaluated in the context of anthropometric profiles. PMID- 30298429 TI - Novel osteoconductive beta-tricalcium phosphate/poly(L-lactide-co-e-caprolactone) scaffold for bone regeneration: a study in a rabbit calvarial defect. AB - The advantages of synthetic bone graft substitutes over autogenous bone grafts include abundant graft volume, lack of complications related to the graft harvesting, and shorter operation and recovery times for the patient. We studied a new synthetic supercritical CO2 -processed porous composite scaffold of beta tricalcium phosphate and poly(L-lactide-co-caprolactone) copolymer as a bone graft substitute in a rabbit calvarial defect. Bilateral 12 mm diameter critical size calvarial defects were successfully created in 18 rabbits. The right defect was filled with a scaffold moistened with bone marrow aspirate, and the other was an empty control. The material was assessed for applicability during surgery. The follow-up times were 4, 12, and 24 weeks. Radiographic and micro-CT studies and histopathological analysis were used to evaluate new bone formation, tissue ingrowth, and biocompatibility. The scaffold was easy to shape and handle during the surgery, and the bone-scaffold contact was tight when visually evaluated after the implantation. The material showed good biocompatibility and its porosity enabled rapid invasion of vasculature and full thickness mesenchymal tissue ingrowth already at four weeks. By 24 weeks, full thickness bone ingrowth within the scaffold and along the dura was generally seen. In contrast, the empty defect had only a thin layer of new bone at 24 weeks. The radiodensity of the material was similar to the density of the intact bone. In conclusion, the new porous scaffold material, composed of microgranular beta-TCP bound into the polymer matrix, proved to be a promising osteoconductive bone graft substitute with excellent handling properties. PMID- 30298431 TI - Sex and sex steroids impact influenza pathogenesis across the life course. AB - Males and females differ in the outcome of influenza A virus (IAV) infections, which depends significantly on age. During a typical seasonal influenza epidemic, young children (< 10 years of age) and aged adults (65+ years of age) are at greatest risk for severe disease, and among these age groups, males tend to suffer a worse outcome from IAV infection than females. Following infection with either pandemic or outbreak strains of IAVs, females of reproductive ages (i.e., 15-49 years of age) experience a worse outcome than their male counterparts. Among females of reproductive ages, pregnancy is one factor linked to an increased risk of severe outcome of influenza, although it is not the sole factor explaining the female-preponderance of severe disease. Small animal models of influenza virus infection illustrate that inflammatory immune responses and repair of damaged tissue following IAV infection also differ between the sexes and impact the outcome of infection. There also is growing evidence that sex steroid hormones, including estrogens, progesterone, and testosterone, directly impact immune responses during IAV infection to alter outcomes. Greater consideration of the combined effects of sex and age as biological variables in epidemiological, clinical, and animal studies of influenza pathogenesis is needed. PMID- 30298432 TI - Developmental origin and sex-specific risk for infections and immune diseases later in life. AB - The intrauterine environment is an important determinant of immunity later in life of the offspring. An altered prenatal immune development can result in a high postnatal risk for infections, chronic immune diseases, and autoimmunity. Many of these immune diseases show a strong sex bias, such as a high incidence of autoimmune diseases and allergies in adult females or a high risk for infections in males. Here, we comprehensively review established pathways and propose novel concepts modulating the risk for such poor immunity during childhood and throughout life. Moreover, we highlight how an adverse fetal environment may affect or aggravate the risk for poor immunity in a sex-specific manner. An improved understanding of a sex-specific susceptibility to poor immunity along with insights on how such risk can be modulated before or around birth will allow the development of tailored prevention strategies. PMID- 30298433 TI - The microgenderome revealed: sex differences in bidirectional interactions between the microbiota, hormones, immunity and disease susceptibility. AB - Sex differences in immunity are well described in the literature and thought to be mainly driven by sex hormones and sex-linked immune response genes. The gastrointestinal tract (GIT) is one of the largest immune organs in the body and contains multiple immune cells in the GIT-associated lymphoid tissue, Peyer's patches and elsewhere, which together have profound effects on local and systemic inflammation. The GIT is colonised with microbial communities composed of bacteria, fungi and viruses, collectively known as the GIT microbiota. The GIT microbiota drives multiple interactions locally with immune cells that regulate the homeostatic environment and systemically in diverse tissues. It is becoming evident that the microbiota differs between the sexes, both in animal models and in humans, and these sex differences often lead to sex-dependent changes in local GIT inflammation, systemic immunity and susceptibility to a range of inflammatory diseases. The sexually dimorphic microbiome has been termed the 'microgenderome'. Herein, we review the evidence for the microgenderome and contemplate the role it plays in driving sex differences in immunity and disease susceptibility. We further consider the impact that biological sex might play in the response to treatments aimed at manipulating the GIT microbiota, such as prebiotics, live biotherapeutics, (probiotics, synbiotics and bacteriotherapies) and faecal microbial transplant. These alternative therapies hold potential in the treatment of both psychological (e.g., anxiety, depression) and physiological (e.g., irritable bowel disease) disorders differentially affecting males and females. PMID- 30298435 TI - Evaluating Completeness of a Radiology Glossary Using Iterative Refinement. AB - A lay-language glossary of radiology, built to help patients better understand the content of their radiology reports, has been analyzed for its coverage and readability, but not for its completeness. We present an iterative method to sample radiology reports, identify "missing" terms, and measure the glossary's completeness. We hypothesized that the refinement process would reduce the number of missing terms to fewer than 1 per report. A random sample of 1000 radiology reports from a large US academic health system was divided into 10 cohorts of 100 reports each. Each cohort was reviewed in sequence by two investigators to identify terms (single words and multi-word phrases) absent from the glossary. Terms marked as new were added to the glossary and hence was shown as matched in subsequent cohorts. This HIPAA-compliant study was IRB-approved; informed consent was waived. The refinement process added a mean of 288.0 new terms per 100 reports in the first 5 cohorts vs. a mean of 66.0 new terms per 100 reports in the last 5 cohorts; the difference was statistically significant (p < .01). After reviewing 500 reports, the review process found fewer than 1 new term per report in each of 500 subsequent reports. The findings suggest that 500 to 1000 reports is adequate to test the completeness of a glossary, and that the glossary after iterative refinement achieved a high level of completeness to cover the vocabulary of radiology reports. PMID- 30298436 TI - Utilization of Structured Reporting to Monitor Outcomes of Doppler Ultrasound Performed for Deep Vein Thrombosis. AB - Determining the clinical impact of imaging exams at the enterprise level is problematic, as radiology reports historically have been created with the content meant primarily for the referring provider. Structured reporting can establish the foundation for enterprise monitoring of imaging outcomes without manual review providing the framework for assessment of utilization and quality. Ultrasound (US) for deep vein thrombosis evaluation (DVT) is an ideal testbed for assessing this functionality. The system standard template for Doppler US for extremity venous evaluation for DVT was updated with a discrete fixed picklist of impression options and implemented system wide. Template utilization and interpretive outcomes were actively monitored and use reinforced as part of standard clinical practice. From January 1, 2017 to December 31, 2017, 9111 US exams for DVT were performed with 8997 utilizing structured reporting (98.75%). Of those in the structured reporting group, 1074 (11.79%) were positive for any type of DVT with 732 (8.03%) reported as Acute/New above the knee. Positive rates for any type of DVT were 10.29% emergency department, 14.17% inpatient, and 13.20% outpatient. While being the lowest positive rate, the emergency department had the highest overall volume of exams. Structured reporting for DVT US assessment outcomes can be implemented with a very high rate of radiologist adoption and adherence providing accurate determination of positive rates, month by month, in differing patient locations. Structured elements can be used to automatically trigger downstream processes; in our institution, this will alert providers in the EHR if the patient does not receive anticoagulation within 2 h of a positive test. This lays the foundation for effective enterprise assessment of imaging outcomes forming the basis of future quality and safety initiatives on optimizing health system resource utilization. PMID- 30298434 TI - Tissue Physiology of Cynomolgus Monkeys: Cross-Species Comparison and Implications for Translational Pharmacology. AB - We previously performed a comparative assessment of tissue-level vascular physiological parameters in mice and rats, two of the most commonly utilized species in translational drug development. The present work extends this effort to non-human primates by measuring tissue- and organ-level vascular volumes (Vv), interstitial volumes (Vi), and blood flow rates (Q) in cynomolgus monkeys. These measurements were accomplished by red blood cell labeling, extracellular marker infusion, and rubidium chloride bolus distribution, respectively, the same methods used in previous rodent measurements. In addition, whole-body blood volumes (BV) were determined across species. The results demonstrate that Vv, Vi, and Q, measured using our methods scale approximately by body weight across mouse, rat, and monkey in the tissues considered here, where allometric analysis allowed extrapolation to human parameters. Significant differences were observed between the values determined in this study and those reported in the literature, including Vv in muscle, brain, and skin and Q in muscle, adipose, heart, thymus, and spleen. The impact of these differences for selected tissues was evaluated via sensitivity analysis using a physiologically based pharmacokinetic model. The blood-brain barrier in monkeys was shown to be more impervious to an infused radioactive tracer, indium-111-pentetate, than in mice or rats. The body weight normalized total BV measured in monkey agreed well with previously measured value in rats but was lower than that in mice. These findings have important implications for the common practice of scaling physiological parameters from rodents to primates in translational pharmacology. PMID- 30298437 TI - The Role of the Integrated Digital Radiology System in Assessing the Impact of Patient Load on Emergency Computed Tomography (CT) Efficiency. AB - Time-critical management is of particular significance in the trauma and emergency setting, where intervals from patient arrival to diagnostic imaging and from imaging to radiology report are key determinants of outcome. This study, based in the Trauma and Emergency Unit of a large, tertiary-level African hospital with a fully digital radiology department, assessed the impact of increased workload on computerised tomography (CT) efficiency. Sequential, customised searches of the institutional radiology information system (RIS) were conducted to define two weekends in 2016 with the lowest and highest emergency CT workloads, respectively. The electronic RIS timestamps defining the intervals between key steps in the CT workflow were extracted and analysed for each weekend. With the exception of radiologist reporting time, workflow steps were significantly prolonged by increased workload. This study highlights the potential role of the integrated digital radiology system in enabling a detailed analysis of imaging workflow, thereby facilitating the identification and appropriate management of bottlenecks. PMID- 30298438 TI - How clinicians integrate humanism in their clinical workplace-'Just trying to put myself in their human being shoes'. AB - INTRODUCTION: Humanism has been identified as an important contributor to patient care and physician wellness; however, what humanism means in the context of medicine has been limited by opinion and a focus on personal characteristics. Our aim was to describe attitudes and behaviours that enable clinicians to integrate humanism within the clinical setting. METHODS: We conducted semi-structured individual interviews with ten clinical faculty to explore how they enact and experience humanism in patient care and clinical teaching. Interpretive description was used to analyze the data qualitatively. RESULTS: Humanism in medicine was described through five themes representing core attitudes and behaviours: whole person care, valuing, perspective-taking, recognizing universality, and relational focus. Whole person care involved recognizing the multiple dimensions of personhood and sensitivity to others' needs; valuing involved respecting and appreciating others; perspective-taking consisted of considering others' perspectives, suspending judgment, and listening; recognizing universality involved acknowledging the shared human condition, finding common ground, transcending roles, and humility; and relational focus was described through multiple relationships between patients, families, clinicians and learners, becoming part of another's story, reciprocal influence, and accompaniment. CONCLUSIONS: Whereas previous descriptions of humanism have focused on clinicians' personal qualities, our research describes a number of attitudinal and behavioural foundations of humanistic care and teaching, grounded in the experiences of clinical faculty. In drawing attention to the holistic and relational elements of humanism, our work highlights how these foundational elements can be more explicitly integrated into patient care, workplace culture, and clinical education.

It should be "DrPH" and not "PhD". PMID- 30298439 TI - The use of PBPK modeling across the pediatric age range using propofol as a case. AB - The project SAFEPEDRUG aims to provide guidelines for drug research in children, based on bottom-up and top-down approaches. Propofol, one of the studied model compounds, was selected because it is extensively metabolized in liver and kidney, with an important role for the glucuronidation pathway. Besides, being a lipophilic molecule, it is distributed into fat tissues, from where it redistributes into the systemic circulation. In the past, both bottom-up (Physiologically based pharmacokinetic, PBPK) and top-down approaches (population pharmacokinetic, popPK) were applied to describe its pharmacokinetics (PK). In this work, a combination of the two was used to check their performance to describe PK in children and neonates (both term and preterm) using propofol as a case compound. First, in vitro data was generated in human liver microsomes and recombinant enzymes and used to develop an adult PBPK model in Simcyp(r). Activity adjustment factors (AAFs) were calculated to account for differences between in vitro and in vivo enzyme activity. Clinical data were analyzed using a 3-compartment model in NONMEM. These data were used to construct a retrograde PBPK model and for qualification of the PBPK models. Once an accurate in vivo clearance was obtained accounting for the contribution of the different metabolic pathways, the resulting PBPK models were challenged with new data for qualification. After that, the constructed adult PPBK model for propofol was extrapolated to the pediatric population. Both the default built-in and in vivo derived ontogeny functions were used to do so. The models were qualified by comparing their predicted PK parameters to published values, and by comparison of predicted concentration-time profiles to available clinical data. Clearance values were predicted well, especially when compared with values obtained from trials where long-term sampling was applied, whereas volume of distribution was lower compared to the most common popPK model predictions. Concentration-time profiles were predicted well up until and including the preterm neonatal population. In this work, it was thus shown that PBPK can be used to predict the PK up to and including the preterm neonatal population without the use of pediatric in vivo data. This work adds weight to the need for further development of PBPK models, especially regarding distribution modeling and the use of in vivo derived ontogeny functions. PMID- 30298441 TI - How Do Early Psychosis Services Define and Operationalize the Duration of Untreated Psychosis? AB - Reducing the duration of untreated psychosis (DUP) is a key aim of early psychosis (EP) care. However, substantial variability in how the start and end points of DUP are defined impact its utility in clinical decision-making, and as an outcome measure. In this study, qualitative interviews were conducted with providers to assess how EP services and providers define, operationalize, and measure DUP. Twenty-five providers across 14 clinics were interviewed. Participants emphasized symptom frequency, conviction, distress caused, and impact when determining psychosis onset. DUP endpoint was typically identified as the first assessment in an episode of care that included an accurate diagnosis, leading to specialty EP treatment. Participants proposed a more structured operationalization of DUP, relative to those historically adopted in the literature. Integrating front-line provider perspectives could improve the accuracy of DUP measurement and address the heterogeneity in how the construct is operationalized across research and practice. PMID- 30298442 TI - Mental Health Service Preferences and Utilization Among Women Veterans in Crisis: Perspectives of Veterans Crisis Line Responders. AB - Women military veterans are at increased risk of suicide compared to non veterans, but little is known about the mental health service preferences and needs of women veterans in crisis. This study used qualitative, secondary source key informant interviews to ascertain the experiences of women veterans in crisis from 54 responders working at the Veterans Crisis Line. Responders indicated that women veterans reported different experiences with Veterans Administration (VA) and non-VA care, though drivers of satisfaction or dissatisfaction were similar. Availability of specialty care, sensitivity to veterans' issues or Military Sexual Trauma, strong provider relationships, and continuity of care contributed to satisfaction; lengthy appointment wait times, limited service options, and insensitivity to veterans' issues contributed to dissatisfaction. Responders suggested that barriers limiting VA access for women veterans are perceived as similar to non-VA care. Findings suggest that caller experiences with providers drive satisfaction with VA and non-VA mental health services. PMID- 30298444 TI - Glucagon-Like Peptide-1 Infusion Suppresses Aldosterone Levels in Healthy Normal Weight Individuals: Double-Blind, Placebo-Controlled Crossover Study. AB - INTRODUCTION: Glucagon-like peptide-1 (GLP-1) has many effects on the human body, but its glucose-lowering effect through its stimulation of insulin secretion is the most significant. GLP-1 also acts on renal function and hemodynamics. The antihypertensive and renoprotective effects of GLP-1 receptor agonists are partly explained by their vasoactive effect and increased natriuresis, but their positive influences on blood pressure and the development and progression of kidney disease are attributed to many effects beyond glycemic control. The aim of this study was to determine how the native gut hormone GLP-1 influences the renin angiotensin-aldosterone system (RAAS). METHODS: Fourteen healthy participants (6 males and 8 females) were included in a double-blind, placebo-controlled crossover study. After overnight fasting and oral sodium loading, participants were randomly assigned to receive either placebo (500 ml of 0.9% saline) or GLP-1 infusion (1.5 pmol/kg/min dissolved in 500 ml of 0.9% saline) over a 3-h period. After 3 and 6 h, the following parameters were measured: glucose, insulin, plasma renin activity, aldosterone, GLP-1, and antidiuretic hormone. After 7 days, the protocol was repeated, except that those who had previously received placebo now received GLP-1 infusion, and those who had previously received GLP-1 now received placebo. RESULTS: Three hours after GLP-1 infusion, aldosterone had decreased by a statistically significant amount (p < 0.008) compared to the baseline level. CONCLUSION: The present study showed that native GLP-1 can decrease aldosterone secretion in a group of healthy individuals, supporting the idea of beneficial outcomes of GLP-1-activating agents on blood pressure and the RAAS. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02130778. PMID- 30298443 TI - Modulatory Effects of Levodopa on Cerebellar Connectivity in Parkinson's Disease. AB - Levodopa has been the mainstay of symptomatic therapy for Parkinson's disease (PD) for the last five decades. However, it is associated with the development of motor fluctuations and dyskinesia, in particular after several years of treatment. The aim of this study was to shed light on the acute brain functional reorganization in response to a single levodopa dose. Functional magnetic resonance imaging (fMRI) was performed after an overnight withdrawal of dopaminergic treatment and 1 h after a single dose of 250 mg levodopa in a group of 24 PD patients. Eigenvector centrality was calculated in both treatment states using resting-state fMRI. This offers a new data-driven and parameter-free approach, similar to Google's PageRank algorithm, revealing brain connectivity alterations due to the effect of levodopa treatment. In all PD patients, levodopa treatment led to an improvement of clinical symptoms as measured with the Unified Parkinson's Disease Rating Scale motor score (UPDRS-III). This therapeutic effect was accompanied with a major connectivity increase between cerebellar brain regions and subcortical areas of the motor system such as the thalamus, putamen, globus pallidus, and brainstem. The degree of interconnectedness of cerebellar regions correlated with the improvement of clinical symptoms due to the administration of levodopa. We observed significant functional cerebellar connectivity reorganization immediately after a single levodopa dose in PD patients. Enhanced general connectivity (eigenvector centrality) was associated with better motor performance as assessed by UPDRS-III score. This underlines the importance of considering cerebellar networks as therapeutic targets in PD. PMID- 30298445 TI - Impact of Definitive Drug-Drug Interaction Testing on Medication Management and Patient Care. AB - BACKGROUND AND OBJECTIVE: Aegis Sciences Corporation developed a test (InterACT RxTM) that objectively and definitively identifies substances known to interact with drug-drug interaction-prone medications commonly prescribed in the treatment of chronic pain and behavioral health disorders. The objective of this study was to assess the severity of identified drug-drug interactions, the reduction in the frequency and severity of identified drug-drug interactions, and the impact of the test on healthcare utilization. METHODS: Patients with chronic pain, behavioral health disorders, or both who had one or more drug-drug interaction tests and one or more drug-drug interactions identified in the study period were included. Drug-drug interaction test results described the number and severity of interactions and detected substances involved in drug-drug interactions. Patients' electronic medical records were obtained to analyze outpatient visits and prescription medications. The cost of outpatient visits was based on the Medicare Physician Fee Schedule. Outcomes were compared between the pre- and post study index periods to determine the impact of the drug-drug interaction test on patient care. RESULTS: A total of 262 patients were included. The majority of drug-drug interactions detected (77.9%) at index were of moderate severity. The number of monthly all-cause and pain-related outpatient visits was reduced in the post-index period compared with the pre-index period (0.74-0.54 and 0.69-0.49, respectively). Associated costs were reduced from US$64.92 to US$51.20, and from US$62.42 to US$47.62, (p < 0.0001 for both) for all-cause and pain-related outpatient visits, respectively. Follow-up drug-drug interaction testing for 43 patients revealed that previously reported drug-drug interactions at the index test were no longer identified in the subsequent test for 39.5% of patients. CONCLUSIONS: Employing a definitive test to detect substances whose interactions may cause adverse drug events can enhance a provider's insights, drive clinical decision making, and improve patient outcomes. PMID- 30298446 TI - Laparoscopic transcystic common bile duct exploration: surgical indications and procedure strategies. AB - BACKGROUND: LTCBDE combined with or without modified techniques is safe and efficacious for the management of gallstones and concomitant, even large, common bile duct (CBD) stones. METHODS: To describe the surgical indications and procedure strategies of laparoscopic transcystic common bile duct exploration (LTCBDE), a retrospective analysis of 205 patients with concomitant gallstones and CBD stones treated using LTCBDE between June 2008 and June 2015 was performed. Clinical data on disease characteristics, methods for cystic duct incision and CBD stone extraction (with or without laser lithotripsy), and surgical outcomes were collected and reviewed. RESULTS: CBD stones were successfully cleared in all patients. No patient was converted to choledochotomy or laparotomy. The cystic duct diameter ranged 3-8 mm, and 85 patients with cystic duct diameter >= 5 mm. The mean time for CBD stone extraction was 25.3 min, with the operative time ranged from 63 to 170 min. Lithotripsy was used in 74 (36.1%) patients among which 26 patients with cystic duct diameter >= 5 mm. Estimated blood loss during surgery was 10-120 ml per patient, and no intra operative blood transfusions were needed. The mean postoperative hospital stay was 5.1 (range 3-7) days, and postoperative complications developed in seven patients. No bile duct injury, stricture, remnant, recurrent stones, or other adverse events were observed during the mean follow-up of 8 months. CONCLUSIONS: Based on preoperative MRCP and intra-operative IOC findings about cystic duct diameter, the diameter of CBD, CBD stone size, we summarized and proposed the surgical indications and suitable techniques and strategies during LTCBDE. PMID- 30298447 TI - The incidence of lymph node metastasis in submucosal early gastric cancer according to the expanded criteria: a systematic review. AB - BACKGROUND: For successful endoscopic treatment of early gastric cancer (EGC), absolute criteria for a curative en bloc resection were initially established to include predominantly differentiated mucosal lesions <= 2 cm in diameter without ulceration. These indications were subsequently expanded to include larger, ulcerated, and predominantly undifferentiated mucosal lesions. In addition, differentiated type adenocarcinomas <= 3 cm with slight submucosal invasion of < 500 um (pT1b1) are regarded as "curative" under the expanded criteria. However, data derived from studies of surgical specimens in patients with pT1b1 EGC have yielded varying rates of lymph node metastasis (LNM). METHOD: A systemic review was conducted using the pooled analysis to calculate the incidence of LNM in pT1b1 EGC, and to investigate whether using a cut-off value of < 300 um would decrease the risk of LNM in patients with submucosal EGC. RESULTS: Nineteen articles were included. 1507 patients with pT1b1 EGC met the expanded indications. The incidence of LNM was 3% (45 out of 1507 patients). In a subgroup analysis of three studies, there was no significant difference in the LNM between pT1b EGC < 300 um and < 500 um [3/121(2.5%) vs. 5/180 (2.8%)] (OR 0.89, 95% CI 0.22-3.54). CONCLUSION: Overall, expanding the indications for endoscopic resection of EGC to include lesions <= 3 cm T1b1 is associated with a potential risk of LNM of 3%. In countries outside of Japan, we found a slightly higher risk of LNM (4.0%). These estimates of LNM should be incorporated into decisions regarding further management of patients with EGC <= 3 cm who are found to have slight submucosal invasion (< 500 um) in an ESD specimen. Standardization of specimen handling and histological evaluation is essential if the Japanese results of endoscopic treatment for EGC are to be successfully applied in other parts of the world. PMID- 30298448 TI - Decreased autophagy was implicated in the decreased apoptosis during decidualization in early pregnant mice. AB - Folate deficiency is a major risk factor of birth defects. Mechanistic studies on folate deficiency resulting in birth defects have mainly focused on fetal development. There have been few studies on folate deficiency from the point of view of the mother's uterus. In our previous study, we demonstrated that folate deficiency inhibits apoptosis of decidual cells, thereby restraining decidualization of the endometrium and impairing pregnancy. In this study, we further investigated the potential mechanism by which folate deficiency decreases endometrial apoptosis during decidualization. To investigate whether endometrium autophagy was inhibited under folate deficiency during decidualization, we performed real-time PCR for endometrial LC3 and P62 on day 6 (D6) to D8 of pregnancy in mice, and both were significantly changed compared to non-folate deficient mice. Western blots showed that LC3-II and P62 were also changed in folate-deficient mice. Compared with control mice, a few punctuate LC3-II structures were detected in the folate deficiency group by immunofluorescence. Transmission electron micrographs of decidual cells on D8 showed that there were no evident autophagosomes in the folate deficiency group. In addition, apoptosis related protein analysis by western blotting, TUNEL staining and flow cytometry showed that decreased endometrial apoptosis on D8 of pregnancy under folate deficiency was reversed after treatment with rapamycin, an autophagy inducer. ROS measurement showed that the endometrium ROS level was reduced by folate deficiency and that rapamycin reversed this effect on day 8 of pregnancy. All the results suggest that inhibiting endometrial autophagy may be implicated in the decreased endometrial apoptosis under folate deficiency during decidualization. PMID- 30298450 TI - Engineering of deglycosylated and plasmin resistant variants of recombinant streptokinase in Pichia pastoris. AB - Streptokinase, a therapeutically important thrombolytic agent, is prone to C terminal degradation and plasmin-mediated proteolytic processing. Since the protein was glycosylated during secretion from Pichia pastoris, therefore, the role of carbohydrate moieties on its stability was analyzed via in vivo blocking of N-glycosylation using tunicamycin where an increased degradation of streptokinase was observed. Further, the in vitro site-directed mutagenesis of the three putative N-glycosylation sites at asparagine residues 14, 265, and 377 to alanine revealed the essentiality of glycosylation of the 14th amino acid residue in its post-translational proteolytic stability without significantly affecting its biological activity. However, the mutation of both Asn265 and Asn377 did not seem to contribute toward its glycosylation but resulted in a 39% lower specific activity in case of the rSK-N265,377A. Moreover, the mutation of all three glycosylation positions drastically reduced the secretory expression of native streptokinase from 347 to 186.6 mg/L for the triple mutant with a 14% lower specific activity of 56,738 IU/mg from 65,808 IU/mg. The secondary structure, tertiary structure, and thermal transition point (45-55 degrees C) of all the deglycosylated variants did not show any significant differences when compared with fully glycosylated native streptokinase using CD and fluorescence spectroscopy. Furthermore, the longer acting plasmin-resistant variants were also developed via the mutation of lysine residues 59 and 386 to glutamine which enhanced its biological stability as a ~ 1.5-fold increase in the caseinolytic zone size was observed in case of rSK-K59Q and also in rSK-K59,386Q mutant without affecting the structural properties. PMID- 30298449 TI - Nur77 promotes cerebral ischemia-reperfusion injury via activating INF2-mediated mitochondrial fragmentation. AB - Mitochondrial fragmentation drastically regulates mitochondrial homeostasis in brain illness. However, the role of mitochondrial fragmentation in cerebral ischemia-reperfusion (IR) injury remains unclear. Nur77, a regulator of mitochondrial homeostasis, is associated with heart and liver IR injury, but its effects on mitochondrial function in cerebral IR injury has not been studied intensively. The aim of our study is to explore whether cerebral IR injury is modulated by Nur77 via modification of mitochondrial homeostasis. Our results indicated that Nur77 was upregulated in reperfused brain tissues. Genetic ablation of Nur77 reduced infarction area and promoted neuron survival under IR burden. Biochemical analysis demonstrated that Nur77 deletion protected mitochondrial function, attenuated mitochondrial oxidative stress, preserved mitochondrial potential, and blocked mitochondria-related cell apoptosis. In addition, we illustrated that Nur77 mediated mitochondrial damage via evoking mitochondrial fragmentation that occurred through increased mitochondrial fission and decreased fusion. Besides, our results also demonstrated that Nur77 controlled mitochondrial fragmentation via upregulating INF2 in a manner dependent on the Wnt/beta-catenin pathway; inhibition of the Wnt pathway abrogated the protective effect of Nur77 deletion on reperfused-mediated neurons. Altogether, our study highlights that the pathogenesis of cerebral IR injury is associated with Nur77 activation followed by augmented mitochondrial fragmentation via an abnormal Wnt/beta-catenin/INF2 pathway. Accordingly, Nur77 dependent mitochondrial fragmentation and the Wnt/beta-catenin/INF2 axis may represent novel therapeutic targets to reduce cerebral IR injury.

AB - OBJECTIVES: To evaluate the effects of hexametaphosphate microparticles (mHMP) or nanoparticles (nHMP) incorporated in glass ionomer cement (GIC) on antimicrobial and physico-mechanical properties, fluoride (F) release, and enamel demineralization. MATERIAL AND METHODS: HMP solutions were obtained at concentrations of 1, 3, 6, 9, and 12%, for screening of antimicrobial activity. Next, mHMP or nHMP at 6, 9, and 12% were incorporated into a resin-modified GIC and the antibacterial activity was evaluated. The resistance to diametral tensile and compressive strength, surface hardness, and degree of monomer conversion as well as F and HMP releases of GICs were determined. Furthermore, specimens were attached to enamel blocks and submitted to pH-cycling, and mineral loss was determined. Parametric and non-parametric tests were performed, after checking data homoscedasticity (p < 0.05). RESULTS: HMP solutions at 6, 9, and 12% demonstrated the best antibacterial activity. GIC containing HMP showed better antibacterial effects at 9 and 12% for nHMP. Regarding F and HMP releases, the highest levels of release occurred for groups containing 9 and 12% nHMP. With the increase in HMP concentration, there was lower mineral loss. However, the incorporation of mHMP or nHMP in GIC reduced values of physico-mechanical properties when compared to the control GIC. CONCLUSIONS: nHMP improves antimicrobial activity and fluoride release, and decreases enamel demineralization, but reduces the physico-mechanical properties of GIC. CLINICAL RELEVANCE: The association of GIC/HMP could be an alternative material for patients at high risk for dental caries and could be indicated for low-stress regions or provisional restorations. PMID- 30298452 TI - Long-term scopolamine treatment and dental caries. AB - OBJECTIVES: To investigate whether scopolamine, an anticholinergic agent which induces hyposalivation, represents a risk factor for the occurrence of dental caries. MATERIALS AND METHODS: A retrospective cohort study was carried out among sailors treated with scopolamine for seasickness. The study population included 370 young healthy male adults (18-30 years old) who served in the Israel Navy between 2012 and 2016. Of these, 66 subjects who were chronically treated with intermittent administration of scopolamine, either by the oral or transdermal route, were assigned to the study group. Documented subject characteristics included age, socioeconomic status, level of education, body mass index, smoking history, and dental hygiene. Follow-up lasted 1 to 3.5 years. RESULTS: Two- to 3.5-year follow-up revealed a higher risk of dental caries in 15 of 16 subjects (93.8%) treated with an average of 50.9 mg scopolamine, in contrast to only 71 of 108 control subjects (65.7%) (RR = 1.43, p = 0.02 [95% CI = 1.18-1.72]). Follow up for 1-1.5 years revealed a lower occurrence of dental caries in both the study group (11/22, 50.0%) and the control group (46/104, 44.2%). Follow-up of 1.5-2 years also revealed less dental caries, in 16/28 subjects (57.1%) in the study group and 51/92 subjects (55.4%) in the control group. The differences were not statistically significant. CONCLUSIONS: In healthy young adults, prolonged intermittent use of scopolamine was found to be a risk factor for the development of dental caries. CLINICAL SIGNIFICANCE: Dental care and hygiene should be intensified when administering hyposalivatory anticholinergic agents.

AB - OBJECTIVES: This in vivo study aimed to compare the marginal discrepancies of zirconia copings manufactured on the basis of two direct intraoral scanning systems and the indirect digitization of a conventional impression. MATERIALS AND METHODS: A total of 63 teeth in 23 patients were prepared to receive full coverage crowns. Subsequently, these teeth were intraorally scanned using CEREC AC Omnicam and Cara TRIOS and a conventional impression was taken with the scannable PVS Flexitime Fast & Scan. The conventional impression was then extraorally digitized using a D700 laboratory scanner. The zirconia copings were manufactured on the basis of the resulting datasets. Silicone replicas of the copings were produced and sectioned for the measurement of the marginal discrepancy under a digital microscope. RESULTS: The statistical analysis showed no significant differences between the two intraoral scanners, the CEREC AC Omnicam (86.09 MUm +/- 61.46 MUm) and the Cara TRIOS (88.95 MUm +/- 54.46 MUm). However, the discrepancies of the zirconia copings obtained from the laboratory scans of conventional impressions (143.29 MUm +/- 100.71 MUm) showed significant differences. Both intraoral scanners achieved a marginal discrepancy below 100 MUm, whereas the laboratory scan exhibited considerably higher values. CONCLUSIONS: The intraoral scanners tested allow for the production of single tooth-restorations with an adequate marginal fit, whereas the production of restorations on the basis of the scan of a conventional impression led to vast marginal gaps. CLINICAL RELEVANCE: The method of digitizing a conventional impression using a laboratory scanner seemed to have reached its limits in the clinical environment. PMID- 30298455 TI - The effects of the timing of exposure to cadmium on the oviposition behavior of Drosophila melanogaster. AB - Animals can greatly increase their fitness by choosing oviposition sites free from damaging substances such as the heavy metal cadmium (Cd). Previous research has shown that Drosophila melanogaster reared on uncontaminated media lay fewer eggs on substrates containing Cd. In this study, we examined the effects of prior exposure to Cd on oviposition site preference. We tested flies that had been exposed to Cd continuously from egg to adult, only during pre-adult stages, or for the 4 days of adulthood prior to testing. We found that flies avoid laying eggs on Cd-contaminated medium and also that flies exposed to Cd as adults laid significantly fewer eggs than controls never exposed to Cd. We did not observe consistent changes in oviposition as a result of pre-adult exposure alone. Our results suggest that the presence of cadmium in the environment, even at low doses and for short periods of time during adulthood, can harm the fitness of Drosophila melanogaster. PMID- 30298454 TI - Are dairy products containing probiotics beneficial for oral health? A systematic review and meta-analysis. AB - OBJECTIVES: To evaluate the effect of probiotic containing in dairy products on oral and salivary parameters. MATERIAL AND METHODS: Electronic searches were performed based on the PICO criteria. Randomized controlled trials in adults/children (P) in which dairy products containing probiotics (I) were compared to controls (C) for establishment of oral health (O) were included. Risk of bias and data extraction were performed. The meta-analysis evaluated the influence of probiotics on Streptococcus mutans (SM), Lactobacillus spp. (LB), and yeast counts, plaque index, and salivary pH. Random or fixed effect models were used, and heterogeneity was tested. RESULTS: Thirty-two studies were included in the qualitative synthesis, and 24 in the meta-analysis. For dichotomous results, individuals who consumed probiotics exhibited decreased scores in SM concentrations (RD 0.15 [0.02, 0.28] p = 0.03, I2 = 70%), but no change was observed for LB (RD 0.10 [- 0.03, 0.23] p = 0.13, I2 = 94%), or yeast levels (RD 0.05 [- 0.02, 0.12] p = 0.7, I2 = 48%). For continuous analysis, both probiotic and control groups presented similar results for SM and LB (MD - 0.55 [ 1.16, 0.07] p = 0.08, I2 = 62%, and RD 0.10 [- 0.03, 0.23] p = 0.13, I2 = 94%, respectively). The consumption of probiotics increased salivary pH (MD 0.20 [0.04, 0.35] p = 0.01, I2 = 46%) and plaque index (MD 0.38 [0.11, 0.65] p = 0.005, I2 = 0%). The probiotic milk reduced SM (MD - 0.59 [- 0.96, - 0.22] p = 0.002, I2 = 0%), and the probiotic yogurt decreased LB counts (RD 0.35 [0.19, 0.51] p < 0.0001, I2 = 0%). CONCLUSIONS: In general, dairy probiotics were effective in reducing SM, increasing salivary pH, and promoting a higher plaque index. Liquid matrices, such as milk and yogurt, seem to be more effective in reducing SM and LB levels. CLINICAL RELEVANCE: Consumption of dairy products containing probiotics could be a supporting method in caries prevention.

PMID- 30298456 TI - Spatiotemporal parameters in sprinters with unilateral and bilateral transfemoral amputations and functional impairments. AB - PURPOSE: Although sprinters with unilateral (UTF) and bilateral transfemoral (BTF) amputations and functional impairments (FIs) without amputation were allocated into different classifications because of the recent revision of the International Paralympic Committee Athletics Rules and Regulations, it is unclear whether running mechanics differ among the three groups. The aim of this study was to investigate the differences in the spatiotemporal parameters of the three groups during 100-m sprint in official competitions. METHODS: Using publicly available Internet broadcasts, we analyzed 11 elite-level sprinters with UTF amputation, 4 sprinters with BTF amputation, and 5 sprinters with FI without amputation. The best personal times for nearly all individuals were included. For each sprinter's race, the average speed, step frequency, and step length were calculated using the number of steps in conjunction with the official race time. RESULTS: Although there were no significant differences in the average speed among the UTF, BTF, and FI groups (7.95 +/- 0.22, 7.90 +/- 0.42, and 7.93 +/- 0.14 m/s, respectively, p = 0.87), those with BTF amputation showed significantly lower step frequency (UTF: 4.20 +/- 0.20 Hz, BTF: 3.71 +/- 0.32 Hz, FI: 4.20 +/- 0.10 Hz, p < 0.05) and longer step length (UTF: 1.90 +/- 0.08 m, BTF: 2.14 +/- 0.02 m, FI: 1.89 +/- 0.06 m, p < 0.05) than the other two groups. CONCLUSION: These results suggest that the step characteristics during sprinting are not the same among sprinters with UTF amputation, BTF amputations, or FI without amputations. PMID- 30298458 TI - Dual roles of mitochondrial fusion gene FZO1 in yeast age asymmetry and in longevity mediated by a novel ATG32-dependent retrograde response. AB - The replicative lifespan of the yeast Saccharomyces cerevisiae models the aging of stem cells. Age asymmetry between the mother and daughter cells is established during each cell division, such that the daughter retains the capacity for self renewal while this ability is diminished in the mother. The segregation of fully functional mitochondria to daughter cells is one mechanism that underlies this age asymmetry. In this study, we have examined the role of mitochondrial dynamics in this phenomenon. Mitochondrial dynamics involve the processes of fission and fusion. Out of the three fusion and three fission genes tested, we have found that only FZO1 is required for the segregation of fully-functional mitochondria to daughter cells and in the maintenance of age asymmetry as manifested in the potential of daughters for a full replicative lifespan despite its deterioration in their mothers. The quality of mitochondria is determined by their turnover, and we have also discovered that deletion of FZO1 reduces mitophagy. Mitochondrial dysfunction elicits a compensatory retrograde response that extends replicative lifespan. Typically, the dysfunction that triggers this response encompasses energy production. The disruption of mitochondrial dynamics by deletion of FZO1 also activates the retrograde response to extend replicative lifespan. We call this novel pathway the mitochondrial dynamics-associated retrograde response (MDARR) because it is distinct in the signal proximal to the mitochondrion that initiates it. Furthermore, the MDARR engages the mitophagy receptor Atg32 on the mitochondrial surface, and we propose that this is due to the accumulation of Atg32-Atg11-Dnm1 complexes on the mitochondrion in the absence of Fzo1 activity. MDARR can be masked by the operation of the 'classic' retrograde response. PMID- 30298459 TI - Longitudinal Comparison of the Effect of Gastric Bypass to Sleeve Gastrectomy on Liver Function in a Bariatric Cohort: Tehran Obesity Treatment Study (TOTS). AB - BACKGROUND: Patients with morbid obesity commonly have fatty liver disease and elevated liver enzymes. While surgery effectively induces weight loss, bariatric techniques may differ regarding liver function improvement. OBJECTIVES: To evaluate and compare the trends of liver function recovery after gastric bypass surgery (GB) with sleeve gastrectomy (SG). SETTING: University hospitals, Iran. METHODS: Adult bariatric candidates without a history of alcohol consumption or other etiologies of liver disease who underwent SG (n = 682) or GB (n = 355) were included. Trends of weight loss parameters and alanine transaminase (ALT), aspartate transaminase (AST), and alkaline phosphatase (ALP) at 0, 6 (in 90.4%), 12 (in 83.5%), and 24 months (in 67.1%) were compared using generalized estimating equations method. RESULTS: Overall, 1037 patients with mean age of 38.4 +/- 11.2 and mean body mass index of 44.9 +/- 6.2 kg/m2 were analyzed. Seventy-eight percent of patients had fatty liver by ultrasound. Both GB and SG patients lost significant weight, with GB patients having a higher percentage of excess weight loss at 24 months (80.1% vs. 75.9%, Pbetween-group = .008). SG patients showed more favorable trends in liver chemistries with significantly lower ALT at 12 months and AST and ALP levels at 6 and 12 months. However, the two groups were comparable at 24 months. Significantly more GB patients developed high ALT at 6 and high AST at 6 and 12 months. Undergoing GB was associated with smaller 0-12-month changes in ALT, AST, and ALP. CONCLUSIONS: Bariatric surgery resulted in improvement in liver function parameters, with SG showing advantages over GB in the first postoperative year. PMID- 30298461 TI - Caplacizumab: First Global Approval. AB - Ablynx, a Sanofi Company, has developed the anti-von Willebrand factor Nanobody(r) caplacizumab (CabliviTM) for the treatment of acquired thrombotic thrombocytopenic purpura (aTTP). Based on positive results in phase II and III trials in patients with aTTP, caplacizumab was recently approved in the EU for the treatment of adults experiencing an episode of aTTP, in conjunction with plasma exchange and immunosuppression. This article summarizes the milestones in the development of caplacizumab leading to this first approval. PMID- 30298460 TI - Low-ranking individuals present high and unstable fecal cortisol levels in provisioned free-ranging adult male rhesus macaques (Macaca mulatta) during the birth season in a mountain area of northern China. AB - Social hierarchy commonly exists in animal societies, affecting both the endocrine functioning and the behavior of animals. In nonhuman primates, the relationship between social rank and cortisol levels varies across species and even within species. Here, we assessed the relationships between social rank and fecal cortisol levels in adult male Taihangshan macaques (rhesus macaques, Macaca mulatta tcheliensis) from the provisioned, free-ranging Wulongkou-2 (WLK-2) group inhabiting Wulongkou Scenic Area, Jiyuan, China. From March to May 2014, we recorded 195 agonistic behaviors and collected 54 fresh fecal samples from eight adult male Taihangshan macaques. Males were assigned a social rank according to an agonistic behavior matrix, and enzyme-linked immunosorbent assay was then used to measure the cortisol concentration in the fecal samples. We found that social rank among the eight male Taihangshan macaques in WLK-2 group followed a strict linear hierarchy, and that fecal cortisol levels were significantly higher and more variable in low-ranking males than in more dominant individuals. Age was not significantly associated with social rank or fecal cortisol levels. Our results suggest that social rank and maintenance of the social hierarchy within the WLK-2 group is a chronic stressor, with low-ranking males maintaining heightened stress levels and enlarged reactive scope relative to dominant males. This provides new support for the theory that social environment can influence endocrine functioning. PMID- 30298462 TI - Automatic Recognition of Posed Facial Expression of Emotion in Individuals with Autism Spectrum Disorder. AB - Facial expression is impaired in autism spectrum disorder (ASD), but rarely systematically studied. We focus on the ability of individuals with ASD to produce facial expressions of emotions in response to a verbal prompt. We used the Janssen Autism Knowledge Engine (JAKE(r)), including automated facial expression analysis software (FACET) to measure facial expressions in individuals with ASD (n = 144) and a typically developing (TD) comparison group (n = 41). Differences in ability to produce facial expressions were observed between ASD and TD groups, demonstrated by activation of facial action units (happy, scared, surprised, disgusted, but not angry or sad). Activation of facial action units correlated with parent-reported social communication skills. This approach has potential for diagnostic and response to intervention measures. Trial Registration NCT02299700. PMID- 30298463 TI - Everything has Its Time: Narrow Temporal Windows are Associated with High Levels of Autistic Traits Via Weaknesses in Multisensory Integration. AB - The present study examined whether fundamental sensory functions such as temporal processing and multisensory integration are related to autistic traits in the general population. Both a narrower temporal window (TW) for simultaneous perception, as measured by a temporal order judgement task, and a reduced ability to engage in multisensory integration during the sound-induced flash illusion task were related to higher levels of autistic traits. Additionally, a narrow TW is associated with high levels of autistic traits due to a deficiency in multisensory integration. Taken together, these findings suggest that alterations in fundamental functions produce a cascading effect on higher-order social and cognitive functions, such as those experienced by people with autism spectrum disorder. PMID- 30298464 TI - Beyond the Nuclear Family: Trends in Children Living in Shared Households. AB - Using data from the 1996-2008 panels of the Survey of Income and Program Participation and the 2009-2016 American Community Survey, we examine trends in U.S. children living in shared households (living with adults beyond their nuclear (parent/parent's partner/sibling) family). We find that although the share of children who lived in a shared household increased over this period, the rise was nearly entirely driven by an increase in three generation/multigenerational households (coresident grandparent(s), parent(s), and child). In 1996, 5.7 % of children lived in a three-generation household; by 2016, 9.8 % did likewise-more than a 4 percentage point increase. More economically advantaged groups (older, more educated mothers, married households) experienced the largest percentage increase in three-generation coresidence, although correlates of coresidence remained largely stable. Decomposition analyses suggest that the rise in Social Security receipt and changes in parental relationship status (less marriage, more single parenthood) most strongly explained the increase in three-generation households. Given the dramatic rise in three-generation households, more research is needed to understand the consequences of these living arrangements for children, their parents, and their grandparents. PMID- 30298465 TI - Interstate Migration and Employer-to-Employer Transitions in the United States: New Evidence From Administrative Records Data. AB - Declines in migration across labor markets have prompted concerns that the U.S. economy is becoming less dynamic. In this study, we examine the relationship between residential migration and employer-to-employer transitions in the United States, using both survey and administrative records data. We first note strong disagreement between the Current Population Survey (CPS) and other migration statistics on the timing and severity of any decline in U.S. interstate migration. Despite these divergent patterns for overall residential migration, we find consistent evidence of a substantial decline in economic migration between 2000 and 2010. We find that composition and the returns to migration have limited ability to explain recent changes in interstate migration. PMID- 30298466 TI - Saving, Sharing, or Spending? The Wealth Consequences of Raising Children. AB - This study uses 1986-2012 National Longitudinal Survey of Youth 1979 cohort data to investigate the relationship between raising children and net worth among younger Baby Boomer parents. I combine fixed-effects and unconditional quantile regression models to estimate changes in net worth associated with having children in different age groups across the wealth distribution. This allows me to test whether standard economic models for savings and consumption over the life course hold for families at different wealth levels. My findings show that the wealth effects of children vary throughout the distribution. Among families at or below the median, children of all ages were associated with wealth declines, likely due to the costs of child-rearing. However, at the 75th percentile and above, wealth increased with the presence of younger children but decreased after those children reached age 18. My results, therefore, provide evidence for a saving and investment model of child-rearing among wealthier families but not among families at or below median wealth levels. For these families, the costs of raising children largely outweighed motivations for saving. PMID- 30298467 TI - Recommendations by the Spanish Society of Hospital Pharmacy, the Spanish Society of Oncology Nursing and the Spanish Society of Medical Oncology for the safe management of antineoplastic medication in cancer patients. AB - AIM: To define recommendations that permit safe management of antineoplastic medication, minimise medication errors and improve the safety of cancer patients undergoing treatment. METHODS: By reviewing the literature and consulting the websites of various health organisations and agencies, an expert committee from the Spanish Society of Hospital Pharmacy and the Spanish Society of Medical Oncology defined a set of safe practices covering all stages of providing cancer therapy to patients. The Spanish Society of Oncology Nursing revised and endorsed the final list. RESULTS: In total, 68 recommendations arranged in five sections were defined. They include issues concerning the training of health professionals, the technological resources needed, treatment planning, informing the patient and his/her family, the processes of prescribing, preparing, dispensing and administering cancer therapy (orally, parenterally or intrathecally), assessing patient adherence and treatment toxicity. CONCLUSIONS: It is essential for healthcare establishments to implement specific measures designed to prevent medication errors, in order to ensure the safety of cancer patients treated with antineoplastic medication. PMID- 30298468 TI - Modulation of cancer cells' radiation response in the presence of folate conjugated Au@Fe2O3 nanocomplex as a targeted radiosensitizer. AB - OBJECTIVES: To investigate the effects of Au@Fe2O3 core-shell nanoparticle (NP), with and without conjugation to folic acid (FA) as a targeting ligand, on radiosensitization of both cancer and healthy cells. METHODS: Au@Fe2O3 NPs were first synthesized, then modified with FA, and finally characterized. Radiation dose enhancement studies were performed on KB cancer cells and L929 healthy cells. NPs at the concentration of 20 ug/ml were first incubated with both cell lines and then different doses of 6 MV X-ray radiation were examined. The end effects were evaluated via MTT assay and flow cytometry using AnnexinV/PI kit. RESULTS: It was indicated that viability of KB cells has a much lower rate than L929 cells when the cells were treated by {(FA-Au@Fe2O3) + (X-ray)} regimen. Cell viability was even decreased significantly when X-ray dose increased. Moreover, flow cytometry studies revealed that FA-targeted NPs induced higher level of apoptosis for KB cancer cells than L929 healthy cells. CONCLUSION: Our findings provide a new perspective on high ability of the synthesized FA-targeted Au@Fe2O3 NPs which may be considered as an efficient radiosensitizer in the process of targeted radiation therapy of cancer. PMID- 30298469 TI - Predictive factors of the treatment outcome in patients with advanced biliary tract cancer receiving gemcitabine plus cisplatin as first-line chemotherapy. AB - BACKGROUND: Few studies have clearly identified the prognostic factors in patients with advanced biliary tract cancer (BTC) receiving gemcitabine plus cisplatin (GC) which is acknowledged as standard chemotherapy regimen. OBJECTIVES: The aim of this study was to identify predictive factors of the overall survival (OS) in advanced BTC patients receiving GC therapy. METHODS: Data of 307 patients with advanced BTC who received GC therapy as the first-line chemotherapy at our institution from January 2007 to June 2017 were reviewed retrospectively. The patients were randomly assigned to the investigation or the validation dataset at the ratio of 2:1. Multivariate analysis was conducted to identify the prognostic factors, a prognostic index is proposed from the investigation dataset, and the usefulness of this index was confirmed in the validation dataset. RESULTS: Multivariate analysis identified poor performance status, elevated serum lactate dehydrogenase, and elevated neutrophil-to lymphocyte ratio as independent unfavorable predictors. The patients could be classified into three groups according to these factors, and it was found that the outcomes differed significantly among the three groups (P = 0.0002, good- vs. intermediate-prognosis groups; P = 0.005, intermediate- vs. poor-prognosis groups). When this index was applied to the validation dataset, the OS was confirmed to differ significantly among the three groups (P = 0.04, good- vs. intermediate-prognosis groups, P < 0.0001, intermediate- vs. poor-prognosis groups). CONCLUSIONS: We identified three predictors of the OS in patients with advanced BTC receiving GC therapy in this study, based on which we could classify the patients into three risk groups. PMID- 30298470 TI - Diagnosis of nontuberculous mycobacterial disease in the era of surveillance chest CT scans. AB - The radiologic surveillance of smokers with low-dose CT scan has led to a significant surge of radiologic incidental findings, including the detection of early stages of pulmonary infections including nontuberculous mycobacteria (NTM). This causes a state of overdiagnosis and potential overtreatment of NTM lung disease. Here we propose a new approach to NTM pulmonary disease in the era of increased CT scanning. PMID- 30298471 TI - Inhaled corticosteroids and risk of upper respiratory tract infection in patients with asthma: a meta-analysis. AB - BACKGROUND: Recent studies have suggested a possible association between respiratory infection and the use of inhaled corticosteroids (ICS). We aimed to ascertain the risk of upper respiratory tract infection (URTI) with long-term inhaled corticosteroid use among patients with asthma. METHODS: Through a comprehensive literature search of PubMed, Cochrane Library, EMBASE, and Google Scholar from inception to May 2018, we included randomized controlled trials of any ICS vs. a control treatment for asthma, with reporting of URTI as an adverse event. We conducted meta-analyses by the Peto approaches to generate summary estimates comparing ICS with non-ICS treatment on the risk of URTI. RESULTS: Seventeen trials (15,336 subjects) were included. Compared with non-ICS treatment, ICSs were associated with a significantly increased risk of URTI (Peto OR, 1.24; 95% CI 1.08-1.42; I2 = 5%, p = 0.002). Subgroup analyses were performed for different dose, both high- and low-dose ICSs were associated with a significantly increased risk of URTI (high dose: Peto OR, 1.46; 95% CI 1.05-2.03; I2 = 0%; p = 0.03) (low dose: Peto OR, 1.20; 95% CI 1.04-1.39; I2 = 25%; p = 0.01). Moreover, fluticasone was observed with an increased risk of URTI (Peto OR, 1.18; 95% CI 1.02-1.38; p = 0.03; heterogeneity: I2 = 21%) but not budesonide, low-dose fluticasone treatment was associated with a significantly higher risk of URTI but not high dose. CONCLUSIONS: This study raises safety concerns about the risk of URTI associated with ICS use in patients with asthma, but it should be further investigated.

PMID- 30298473 TI - A phase III, open-label, single-arm, study to evaluate the safety and immunogenicity of a trivalent, surface antigen inactivated subunit influenza virus vaccine produced in mammalian cell culture (Optaflu(r)) in healthy adults. AB - Vaccination is an essential tool in reducing the impact of seasonal influenza infections. The viral strains responsible for seasonal outbreaks vary annually, and preventive vaccines have to be adapted accordingly. The aim of this study was to evaluate the safety, clinical tolerability and the antibody response to each of the three influenza vaccine antigens after vaccination with a cell-derived, trivalent, surface antigen, inactivated influenza vaccine (TIVc), as measured by single radial haemolysis (SRH) or haemagglutination inhibition (HI) assay in accordance with European Union licensing guidelines in place for years 2013/2014. This phase 3, open-label, single-arm study enrolled 126 healthy adults divided into two age groups (63 subjects aged 18 to <= 60 years and 63 subjects aged >= 61 years). Antibody titres were measured before and 21 days after vaccination. Adverse events were determined using diary cards, interviews and reviews of the available medical records. One subject was lost to follow-up and three subjects had protocol deviations. Following vaccination, protective HI antibody titres (>= 1:40) were detected in 100%, 97%, and 94% of the younger adults (18-<= 60 years) and in 97%, 95%, and 80% of the older adults (>= 61 years) against the A (H1N1), A (H3N2), and B influenza strains respectively. The antibody response licensing criteria were met in both age groups. Solicited adverse events were reported by 57% subjects 18 to <= 60 years and 35% subjects >= 61 years. Among the younger adults 51% had local and 27% had systemic adverse events, whereas of the older subjects 29% had local and 13% had systemic adverse events (mainly injection site pain or headache in both age groups). Unsolicited adverse events at least possibly related to the vaccine were mild and detected in 3% of the younger adults and none of the older adults. Overall, the trivalent, surface antigen, inactivated subunit influenza virus vaccine produced in mammalian cell culture proved to be safe and immunogenic in younger and older healthy adults. PMID- 30298474 TI - Why is this Happening? A Brief Measure of Parental Attributions Assessing Parents' Intentionality, Permanence, and Dispositional Attributions of Their Child with Conduct Problems. AB - We present and evaluate a new self-report measure of parental attributions developed for assessing child causal and dispositional attributions in parenting interventions. The Parent Attribution Measure (PAM) ascribes attributions along first-order dimensions of intentionality, permanence, likeability, and disposition, and a higher-order Total Scale. The psychometric analyses involved participants drawn from populations of clinical (n = 318) and community-based families (n = 214) who completed questionnaires assessing parental attributions, parenting behaviours, parental depression, parental feelings about the child, and child behavioural problems. Confirmatory factor analysis indicated that a 3 factor hierarchical structure provided a close fitting model. The model with intentionality, permanence, and disposition (consolidating likeability and disposition) dimensions as first-order factors grouped under a higher-order general factor was validated in independent samples and demonstrated sound psychometric properties. The PAM presents as a brief measure of parental attributions assessing parents' intentionality, permanence, and dispositional attributions of their child with conduct problems. PMID- 30298475 TI - Comparison of In Vitro Stereoselective Metabolism of Bupropion in Human, Monkey, Rat, and Mouse Liver Microsomes. AB - BACKGROUND AND OBJECTIVES: Bupropion is an atypical antidepressant and smoking cessation aid associated with wide intersubject variability. This study compared the formation kinetics of three phase I metabolites (hydroxybupropion, threohydrobupropion, and erythrohydrobupropion) in human, marmoset, rat, and mouse liver microsomes. The objective was to establish suitability and limitations for subsequent use of nonclinical species to model bupropion central nervous system (CNS) disposition in humans. METHODS: Hepatic microsomal incubations were conducted separately for the R- and S-bupropion enantiomers, and the formation of enantiomer-specific metabolites was determined using LC-MS/MS. Intrinsic formation clearance (CLint) of metabolites across the four species was determined from the formation rate versus substrate concentration relationship. RESULTS: The total clearance of S-bupropion was higher than that of R-bupropion in monkey and human liver microsomes. The contribution of hydroxybupropion to the total racemic bupropion clearance was 38%, 62%, 17%, and 96% in human, monkey, rat, and mouse, respectively. In the same species order, threohydrobupropion contributed 53%, 23%, 17%, and 3%, and erythrohydrobupropion contributed 9%, 14%, 66%, and 1.3%, respectively, to racemic bupropion clearance. CONCLUSION: The results demonstrate that phase I metabolism in monkeys best approximates that observed in humans, and support the preferred use of this species to investigate possible pharmacokinetic factors that influence the CNS disposition of bupropion and contribute to its high intersubject variability. PMID- 30298476 TI - The Influence of Caffeine Supplementation on Resistance Exercise: A Review. AB - This paper aims to critically evaluate and thoroughly discuss the evidence on the topic of caffeine supplementation when performing resistance exercise, as well as provide practical guidelines for the ingestion of caffeine prior to resistance exercise. Based on the current evidence, it seems that caffeine increases both maximal strength and muscular endurance. Furthermore, power appears to be enhanced with caffeine supplementation, although this effect might, to a certain extent, be caffeine dose- and external load-dependent. A reduction in rating of perceived exertion (RPE) might contribute to the performance-enhancing effects of caffeine supplementation as some studies have observed decreases in RPE coupled with increases in performance following caffeine ingestion. However, the same does not seem to be the case for pain perception as there is evidence showing acute increases in resistance exercise performance without any significant effects of caffeine ingestion on pain perception. Some studies have reported that caffeine ingestion did not affect exercise-induced muscle damage, but that it might reduce perceived resistance exercise-induced delayed-onset muscle soreness; however, this needs to be explored further. There is some evidence that caffeine ingestion, compared with a placebo, may lead to greater increases in the production of testosterone and cortisol following resistance exercise. However, given that the acute changes in hormone levels seem to be weakly correlated with hallmark adaptations to resistance exercise, such as hypertrophy and increased muscular strength, these findings are likely of questionable practical significance. Although not without contrasting findings, the available evidence suggests that caffeine ingestion can lead to acute increases in blood pressure (primarily systolic), and thus caution is needed regarding caffeine supplementation among individuals with high blood pressure. In the vast majority of studies, caffeine was administered in capsule or powder forms, and therefore the effects of alternative forms of caffeine, such as chewing gums or mouth rinses, on resistance exercise performance remain unclear. The emerging evidence suggests that coffee might be at least equally ergogenic as caffeine alone when the caffeine dose is matched. Doses in the range of 3-9 mg.kg-1 seem to be adequate for eliciting an ergogenic effect when administered 60 min pre-exercise. In general, caffeine seems to be safe when taken in the recommended doses. However, at doses as high as 9 mg.kg-1 or higher, side effects such as insomnia might be more pronounced. It remains unclear whether habituation reduces the ergogenic benefits of caffeine on resistance exercise as no evidence exists for this type of exercise. Caution is needed when extrapolating these conclusions to females as the vast majority of studies involved only male participants. PMID- 30298477 TI - Modeling the Benefits of Cooperative Drafting: Is There an Optimal Strategy to Facilitate a Sub-2-Hour Marathon Performance? AB - BACKGROUND: During a race, competing cyclists often cooperate by alternating between leading and drafting positions. This approach allows them to maximize velocity by using the energy saved while drafting, a technique to reduce the overall drag by exploiting the leader's slipstream. We have argued that a similar cooperative drafting approach could benefit elite marathon runners in their quest for the sub-2-hour marathon. OBJECTIVE: Our aim was to model the effects of various cooperative drafting scenarios on marathon performance by applying the critical velocity concept for intermittent high-intensity running. METHODS: We used the physiological characteristics of the world's most elite long-distance runners and mathematically simulated the depletion and recovery of their distance capacity when running above and below their critical velocity throughout a marathon. RESULTS: Our simulations showed that with four of the most elite runners in the world, a 2:00:48 (h:min:s) marathon is possible, a whopping 2 min faster than the current world record. We also explored the possibility of a sub-2 hour marathon using multiple runners with the physiological characteristics of Eliud Kipchoge, arguably the best marathon runner of our time. We found that a team of eight Kipchoge-like runners could break the sub-2-hour marathon barrier. CONCLUSION: In the context of cooperative drafting, we show that the best team strategy for improving marathon performance time can be optimized using a mathematical model that is based on the physiological characteristics of each athlete. PMID- 30298478 TI - Ankle Bracing is Effective for Primary and Secondary Prevention of Acute Ankle Injuries in Athletes: A Systematic Review and Meta-Analyses. AB - BACKGROUND: Ankle bracing has been verified as being effective for secondary prevention of ankle injuries. However, new studies have recently been published that are not included in previous meta-analyses. Furthermore, the effects of bracing for primary prevention of ankle injuries are still unclear. OBJECTIVE: The objective of this article was to systematically review the literature about the effectiveness of ankle bracing on primary and secondary prevention of acute ankle injuries in athletes. METHODS: We searched PubMed, EMBASE, SPORTDiscus, CINAHL, and PEDro databases for eligible articles until July 2018. Randomized controlled trials that studied ankle bracing vs. no intervention for athletes were included. Risk of bias was assessed with the Cochrane Risk of Bias tool. Meta-analyses were conducted to study the effect of ankle bracing for primary and secondary prevention of ankle injuries. The Grading of Recommendation Assessment, Development, and Evaluation method was used to determine the quality of evidence. RESULTS: We included six randomized controlled trials. Significant risk ratios of 0.53 (95% confidence interval 0.32-0.88) and 0.37 (95% confidence interval 0.24 0.58) were found in favor of ankle bracing vs. no ankle bracing for primary (low quality of evidence, I2 = 77%) and secondary prevention (moderate quality of evidence, I2 = 0%) of acute ankle injuries. Numbers needed to treat were 26 and 12 for the primary and secondary prevention of acute ankle injuries. CONCLUSIONS: Ankle bracing is effective for primary and secondary prevention of acute ankle injuries among athletes. However, conclusions in regard to primary prevention should be drawn cautiously because of the low quality of evidence and significant heterogeneity. PMID- 30298481 TI - Dermatologic Conditions of the Early Post-Transplant Period in Hematopoietic Stem Cell Transplant Recipients. AB - Hematopoietic stem cell transplants (HSCTs) are used to treat a variety of conditions, including hematologic malignancies, bone marrow failure syndromes, and immunodeficiencies. Over 60,000 HSCTs are performed annually worldwide, and the numbers continue to increase. Indeed, as new conditioning regimens develop, more and more individuals, including those of older age, will be eligible for transplants. Nevertheless, although HSCTs are clearly a life-saving and necessary treatment for thousands of patients per year, there is still substantial morbidity and mortality associated with the procedure. Of note, skin eruptions in the post-HSCT period are frequent and often significantly reduce quality of life in recipients. Moreover, these cutaneous findings sometimes herald an underlying systemic condition, presenting possible opportunities for timelier intervention. Dermatologists therefore play a vital role in distinguishing life-threatening conditions from benign issues and prompting recognition of critical complications earlier in their course. This article aims to review the major dermatologic conditions occurring in the early post-HSCT period. PMID- 30298480 TI - Over 50 Years of Researching Force Profiles in Rowing: What Do We Know? AB - There has been substantial interest in the mechanisms underpinning the skilled movements of on-water rowing for more than 150 years. Contemporary attention from biomechanical research has focused on the important relationship between kinetics (such as force application at the oar) and performance. A range of instrumentation systems have been developed and used in both academic and applied training contexts to better understand this relationship. Both qualitative and quantitative analytical approaches have been used in conjunction with these instrumentation systems for observing differences in propulsive force patterns between rowers. Despite the use of these analytical approaches, there is still limited consensus surrounding which characteristics of force profiles are associated with better rowing performance. Newell's model of constraints is provided as a framework for understanding why this lack of clarity exists surrounding force profile characteristics and performance. Further to this, direction for further research is provided by a framework that outlines two main streams: (1) exploration of constraints and how they are related to force profile characteristics; and (2) after controlling for constraints, exploration of performance and how it is related to force profile characteristics. These two steps are sequential, with an understanding of constraints influencing how we understand the interaction of force profiles and performance. PMID- 30298479 TI - An Updated Systematic Review of Childhood Physical Activity Questionnaires. AB - BACKGROUND AND OBJECTIVE: This review is an update of a previous review published in 2010, and aims to summarize the available studies on the measurement properties of physical activity questionnaires for young people under the age of 18 years. METHODS: Systematic literature searches were carried out using the online PubMed, EMBASE, and SPORTDiscus databases up to 2018. Articles had to evaluate at least one of the measurement properties of a questionnaire measuring at least the duration or frequency of children's physical activity, and be published in the English language. The standardized COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist was used for the quality assessment of the studies. RESULTS: This review yielded 87 articles on 89 different questionnaires. Within the 87 articles, 162 studies were conducted: 103 studies assessed construct validity, 50 assessed test-retest reliability, and nine assessed measurement error. Of these studies, 38% were of poor methodological quality and 49% of fair methodological quality. A questionnaire with acceptable validity was found only for adolescents, i.e., the Greek version of the 3-Day Physical Activity Record. Questionnaires with acceptable test-retest reliability were found in all age categories, i.e., preschoolers, children, and adolescents. CONCLUSION: Unfortunately, no questionnaires were identified with conclusive evidence for both acceptable validity and reliability, partly due to the low methodological quality of the studies. This evidence is urgently needed, as current research and practice are using physical activity questionnaires of unknown validity and reliability. Therefore, recommendations for high-quality studies on measurement properties of physical activity questionnaires were formulated in the discussion. PROSPERO REGISTRATION NUMBER: CRD42016038695. PMID- 30298482 TI - [Analysis of audiological characteristics and genetic background in patients with nonsyndromic deafness and mitochondrial DNA 1555A>G mutation]. AB - OBJECTIVE: To analyze the audiological features and genetic background of patients carrying mitochondrial DNA(mtDNA) 1555A>G mutation and factors which may influence the extent of nonsyndromic hearing loss associated with the mutation. METHODS: A literature search was carried out on databases including PubMed, CNKI, Wanfang, and VIP. Combined with author's data, the clinical features of the patients, in particular audiological characteristics, were summarized. RESULTS: A total of 857 effective cases were collected and analyzed. A significantly correlation was identified between history of aminoglycosides exposure and extent of hearing loss, in addition with a negative correlation between the age of onset and extent of hearing-impairment. Drug exposure was corelated with the age of onset but independent to the loss of high-frequency hearing loss. Heteroplasmies had a reverse correlation with the degree of hearing loss. Among the haplotypes of mitochondrial DNA, haplotype D was the most common one, while haplotype B had the highest penetrance. CONCLUSION: Nonsyndromic hearing loss associated with mitochondrial DNA 1555A>G mutation is influenced by factors such as aminoglycosides exposure, age, proportion of mutation, and haplotype of the mitochondrial DNA. Analysis of clinical cases is critical for identifying individuals carrying deafness susceptibility mutations and is the first step for early diagnosis. PMID- 30298483 TI - [Analysis of mutations of 4 common genes among 216 patients with non-syndromic hearing impairment]. AB - OBJECTIVE: To explore the characteristics of mutations 4 common deafness-related genes among 216 patients from Shanghai area with non-syndromic hearing impairment (NSHI). METHODS: Thirteen mutation sites in the four genes, namely GJB2 (c.35delG, c.176del16, c.235delC, c.299delAT, and c.155delTCTG), SLC26A4 (c.IVS7 2A>G, c.2168A>G, and c.1229C>T), mtDNA 12SrRNA (m.1494C>T, m.1555A>G, m.7445A>G, and m.12201T>C) and GJB3 (c.538C>T) were detected among the 216 patients and 41 individuals with normal hearing. The frequency and types of mutations were compared between the two groups. RESULTS: Among the 216 NSHI patients, the total detection rate was 16.20% (35/216). GJB2 mutations were found in 17(7.87%) of the 216 patients, which included 5 cases with homozygous c.235delC mutation, 5 with homozygous c.235delC mutation, 1 with homozygous c.299delAT mutation, and 1 with homozygous c.299delAT mutation. c.235delC and 299delAT mutations were found in 5 cases. SLC26A4 mutation was found in 12(5.56%) of the 216 patients, which included 2 cases with homozygous c.IVS7-2A>G mutation, 9 with homozygous c.IVS7 2A>G mutation, and 1 with homozygous c.2168A>G mutation. Homogeneous mtDNA 12SrRNA m.1555A>G mutation was found in 6(2.78%) of the 216 patients. No GJB3 gene mutation was detected. No mutation of the 4 genes were detected in the 41 individuals with normal hearing. In 2 cases of the 12 patients with SLC26A4 gene mutation, CT scan of the temporal bone has confirmed expansion of vestibular aqueduct. CONCLUSION: Above results indicated that GJB2 and SLC26A4 were the major genes involved with hearing loss in Shanghai area. PMID- 30298484 TI - [Genetic analysis of 100 fetuses with cleft lip with or without palate]. AB - OBJECTIVE: To explore the genetic basis for fetuses with cleft lip and palate. METHODS: For 100 fetuses diagnosed with cleft lip with or without palate, G banding chromosomal karyotyping and copy number variation sequencing (CNV-seq) were carried out on chorionic villi, amniotic fluid or cordocentesis samples. RESULTS: No genomic abnormality was found among 49 fetuses with isolated cleft lip and palate, while 12 genomic aberrations were found among 51 fetuses with syndromic cleft lip and palate, which included 4 cases with trisomy 13, 2 cases with trisomy 18, 1 with X chromosome aneuploidy, 2 with other chromosomal aneuploidies and 3 with pathogenic CNVs. CONCLUSION: The incidence of genomic abnormalities in fetuses with cleft lip and palate was high. In addition to chromosomal abnormalities, attention should also be paid to pathogenic CNVs. PMID- 30298485 TI - [Mutation analysis of four pedigrees affected with hypophosphatemic rickets through targeted next-generation sequencing]. AB - OBJECTIVE: To detect potential mutations of PHEX gene in four pedigrees affected with hypophosphatemic rickets (HR) and provide prenatal diagnosis for a fetus at 13th gestational week. METHODS: The coding regions and exon/intron boundaries of PHEX, FGF23, DMP1, ENPP1, CLCN5 and SLC34A3 genes of the probands were analyzed by targeted next-generation sequencing (NGS). Suspected mutations were verified by Sanger sequencing among unaffected relatives and 200 unrelated healthy individuals. Deletions were confirmed by multiplex ligation-dependent probe amplification (MLPA) detection of probands, unaffected relatives and 20 unrelated healthy individuals. Prenatal diagnosis for a fetus with high risk was carried out through MLPA analysis. RESULTS: Four PHEX mutations were respectively detected in the pedigrees, which included c.850-3C>G, exon 11 deletion, exon 13 deletion and c.1753G>A (p.G585R). Among these, exon 11 deletion, exon 13 deletion and c.1753G>A (p.G585R) were novel mutations and not found among unaffected relatives and healthy controls. In pedigree 3, the same mutation was not found in the fetus. CONCLUSION: Mutations of the PHEX gene probably underlies the disease among the four pedigrees. NGS combined with Sanger sequencing and/or MLPA detection can ensure accurate diagnosis for this disease. PMID- 30298486 TI - [Analysis of PHEX gene mutations in three pedigrees affected with hypophosphatemic rickets]. AB - OBJECTIVE: To explore the molecular basis for three pedigrees affected with hypophosphatemia vitamin D resistant rickets (X-linked hypophosphatemia, XLH). METHODS: Peripheral blood samples from the three pedigrees were collected. Following DNA extraction, the 11 exons and flanking regions of the PHEX gene were subjected to PCR amplification and direct sequencing. Pathogenicity of identified mutations was evaluated through genotype-phenotype correlation. RESULTS: For pedigrees 1 and 2, pathogenic mutations were respectively identified in exon 8 (c.871C>T, p.R291X) and exon 15 (c.1601C>T, p.P534L) of the PHEX gene. For pedigree 3, a novel mutation (c.1234delA, p.S412Vfs*12) was found in exon 11 of the PHEX gene, which caused shift the reading frame and premature termination of protein translation. CONCLUSION: The three mutations probably account for the XLH in the affected pedigrees. The discovery of novel mutations has enriched the spectrum of PHEX gene mutations. PMID- 30298487 TI - [Study of RET proto-oncogene mutations in two pedigrees affected with multiple endocrine neoplasia type 2A]. AB - OBJECTIVE: To study the pattern of RET proto-oncogene mutations in two pedigrees affected with multiple endocrine neoplasia type 2A (MEN2A). METHODS: Peripheral blood samples were collected from members of the two pedigrees, with total genomic DNA extracted for polymerase chain reaction (PCR). PCR products of 7 exons of the RET proto-oncogene (including exons 8, 10, 11, 13, 14, 15, 16) which have higher mutation rates were purified and subjected to direct sequencing. Suspected mutations in the 2 probands were verified in other members of the pedigrees. To exclude other mutations, PCR products of remaining 14 exons were sequenced in the proband from pedigree 1. RESULTS: A novel heterozygous mutation, 1893-1895delCGA, was detected in exon 11 of the RET proto-oncogene among 3 patients and 2 unaffected members from pedigree 1, while a heterozygous mutation, Cys634Arg, was detected in exon 11 among 2 patients and 1 unaffected family member from pedigree 2. CONCLUSION: The heterozygous 1893-1895delCGA and Cys634Arg mutations of the RET proto-oncogene probably underlie the disease in the two pedigrees. Above discovery has enriched the human gene mutation database. PMID- 30298488 TI - [Genetic screening and prenatal diagnosis for high risk families of Fragile X syndrome]. AB - OBJECTIVE: To assess the value of genetic testing for Fragile X syndrome (FXS). METHODS: A domestically made diagnostic kit based Tri-primer-PCR method was used to detect mutations of the FMR1 gene among 6 pedigrees with unexplained intellectual disability. The results were verified by methylation PCR and Southern blotting. RESULTS: Pedigrees 1 and 6 were positive for the screening. In pedigree 1, a full-mutation allele with methylation was identified in the proband and his mother, which was passed on to the fetus. In pedigree 6, the proband was mosaic for a full-mutation allele and a pre-mutation allele. His sister was asymptomatic with a full-mutation. His mother carried pre-mutation allele, while his father and sister's baby were normal. The number of CGG repeats of the pedigrees 2 to 5 were in the normal range. CONCLUSION: Genetic testing can provide an effective way to prevent FXS caused by FMR1 mutations and enable prenatal diagnosis for families with a high risk for the disease. PMID- 30298489 TI - [Analysis of GCDH gene mutations in 3 patients from Fujian area with glutaric academia type I]. AB - OBJECTIVE: To explore clinical features and mutation types in patients from Fujian area with glutaric academia type I(GA I). METHODS: Serum acylcarnitine and urine organic acid of 3 patients were determined with tandem mass spectrometry and gas chromatographic mass spectrometry. The patients also underwent magnetic resonance imaging analysis for the cranial region. Genomic DNA was extracted from peripheral blood samples, and the 12 exons and flanking regions of the GCDH gene were amplified with PCR and subjected to direct DNA sequencing. One hundred healthy newborns were used as controls. RESULTS: Mutations of the GCDH gene were identified in all of the 3 patients. Two patients have carried compound heterozygous mutations including c.1244-2A>C and c.1147C>T(p.R383C), c.406G>T(p.G136C) and c.1169G>A(p.G390E), respectively. One has carried homozygous c.1244-2A>C mutation. The same mutations were not detected among the 100 healthy newborns. Only one patient received early intervention and did not develop the disease. The other two had irreversible damagesto their intelligence. CONCLUSION: c.1169G>A(p.G390E) is likely pathogenic mutations for GA I patients from Fujianarea. Early screening of neonatal metabolic diseases is crucial for such patients. PMID- 30298490 TI - [Differential expression and bioinformatics analysis of microRNA in peripheral blood mononuclear cells from patients with aplastic anemia]. AB - OBJECTIVE: To study differential expression of microRNA (miRNA) in peripheral blood mononuclear cells (PBMNC) from patients with different types of aplastic anemia (AA) and explore the role of miRNA in the pathogenesis of AA. METHODS: miRNA microarray were used to determine the differential expression profile of miRNA in PBMNC from patients with AA. Real-time quantitative polymerase china reaction (RQ-PCR) was used to verify the differential expression of miRNA. Candidate miRNA were analyzed with bioinformatics tools. RESULTS: Compared with the normal controls, 6 miRNAs were up-regulated and 10 were down-regulated in patients with severe aplastic anemia (SAA), while 24 miRNAs were up-regulated and 12 were down-regulated in patients with chronic non-severe aplastic anemia (CAA). Compared with CAA patients, 4 miRNAs were up-regulated and 11 were down-regulated in SAA patients. Compared with normal controls, 3 miRNAs were up-regulated and 4 were down-regulated in both SAA and CAA patients. As verified by RQ-PCR, expression of miR-155-5p and miR-1260b were increased in both CAA and SAA patients compared with the normal controls (P<0.01). The expression of miR-155-5p and miR-1260b of CAA patients were higher than that of SAA patients (P<0.01). Bioinformatics analysis showed that target genes of miR-155-5p and miR-1260b may be involved in regulation of cell metabolism, gene expression and transcription, TNF signaling pathway, B cell receptor signaling pathway, Fc gamma R-mediated phagocytosis and other signaling process. CONCLUSION: There are characteristic differential expression profiles of miRNA in PBMNC from CAA and SAA patients, in which miRNA-155-5p and miRNA-1260b are both up-regulated. The common target gene predicted for miRNA-155-5p and miRNA-1260b is ETS1. miRNA-155-5p and miRNA-1260b may act synergistically to inhibit the expression of ETS1 and promote differentiation of Th17, therefore play an important role in the pathogenesis of AA. PMID- 30298491 TI - [Analysis of genotype-phenotype correlation for a novel MYH7-D554Y mutation identified in an ethnic Han Chinese pedigree affected with hypertrophic cardiomyopathy]. AB - OBJECTIVE: To explore the genotype-phenotype correlation of a MYH7-D554Y mutation identified in an ethnic Han Chinese pedigree affected with hypertrophic cardiomyopathy. METHODS: Ninety six cardiovascular disease-related genes were detected in the proband by exonic amplification and high-throughput sequencing. Suspected mutations were verified by Sanger sequencing among 300 healthy controls as well as family members of the proband. The pathogenicity and conservation of the detected mutations were analyzed with ClustalX, MutationTaster, PolyPhen-2, Provean and SIFT software. RESULTS: Four of the 5 first-degree relatives of the proband were diagnosed with hypertrophic cardiomyopathy. The proband has featured extremely hypertrophic left ventricular wall with a maximal thickness of 35 mm. Genetic testing showed that four of them have carried a heterozygous c.1660G>T (p.Asp554Tyr) mutation of the MYH7 gene, who the remaining one was phenotypically normal and did not carry the mutation. The mutation has not been recorded by the Human Gene Mutation Database (HGMD) and other databases. Bioinformatics analysis suggested that the mutation site is highly conserved and that the mutation is pathogenic. CONCLUSION: The p.Asp554Tyr mutation of the MYH7 gene probably underlies the hypertrophic cardiomyopathy in this pedigree. PMID- 30298492 TI - [Analysis of TGFBI gene mutation in a pedigree affected with corneal dystrophy]. AB - OBJECTIVE: To detect potential mutation in a large Chinese pedigree affected with congenital corneal dystrophy. METHODS: Two patients from the pedigree were subjected to whole exome sequencing to determine the candidate gene. Suspected mutation was verified in 13 additional members by directional Sanger sequencing. Ccorrelation between genotype and phenotype was explored. RESULTS: A missense mutation, c.1877A>C (p.His626Pro), was detected in exon 14 of the TGFBI gene in 8 patients from the pedigree, but not in five unaffected members and 100 unrelated healthy controls. Respectively, the mutation was predicted as "affecting protein function", "probably damaging" and "disease causing" by SIFT, PolyPhen-2 and MutationTaster. CONCLUSION: The c.1877A>C mutation of the TGFBI gene probably underlies the disease in this pedigree. PMID- 30298493 TI - [Analysis of clinical phenotypes and KCNJ2 gene mutations in a Chinese pedigree affected with Andersen-Tawil syndrome]. AB - OBJECTIVE: To analyze the clinical phenotypes of a pedigree affected with periodic paralysis and explore its molecular basis. METHODS: Clinical data and peripheral blood samples of the pedigree were collected. The proband and his father both complained of periodic paralysis and dysmorphic features. The exome of the proband was screened using Roche NimbleGen probes, and the results were confirmed by Sanger sequencing. Suspected mutations were subjected to bioinformatic and gene-disease correlation analysis. RESULTS: A c.653G>A (p.R218Q) mutation of the KCNJ2 gene was detected in both the proband and his father. Bioinformatics analysis suggested it to be pathogenic. CONCLUSION: The clinical manifestation of the pedigree was suggestive of Andersen-Tawil syndrome. KCNJ2 c.653G>A (p.R218Q) was the pathogenic mutation in this pedigree. PMID- 30298494 TI - [Mutation analysis and prenatal diagnosis for a pedigree affected with maple syrup urine disease]. AB - OBJECTIVE: To carry out mutation analysis for a pedigree affected with maple syrup urine disease (MSUD). METHODS: Clinical data of the proband was collected. Potential mutations of the BCKDHA and BCKDHB genes were analyzed by PCR and Sanger sequencing. Prenatal diagnosis was provided to a high-risk fetus at 12th gestational week through chorionic villus sampling. RESULTS: Two heterozygous mutations c.284G>C (p.Gly95Ala) and c.853C>T (p.Arg285*) of the BCKDHB gene were identified in the proband, which were inherited from his mother and father, respectively. Among these, c.853C>T (p.Arg285*) was known to be pathogenic, while c.284G>C (p.Gly95Ala) was a novel mutation. Prenatal diagnosis showed that the fetus has inherited the c.284G>C (p.Gly95Ala) mutation from its mother but no mutation from its father. After birth, the infant appeared to be healthy. CONCLUSION: The compound heterozygous mutations c.284G>C (p.Gly95Ala) and c.853C>T (p.Arg285*) probably underlie the pathogenesis of MUSD in the proband. Mutation analysis can facilitate prenatal diagnosis and genetic counseling for the affected families. PMID- 30298495 TI - [Analysis of TCOF1 mutation in a Chinese patient with Treacher-Collins syndrome]. AB - OBJECTIVE: To detect potential mutation of TCOF1 gene in a Chinese family affected with Treacher-Collins syndrome. METHODS: Clinical data of the patient was collected. The analysis included history taking, clinical examination and genetic testing. All coding regions of the TCOF1 gene were subjected to PCR amplification and Sanger sequencing. RESULTS: A novel mutation c.2261ins G (p.E95X) of the TCOF1 gene was discovered in the patient. The same mutation was not found in his parents and 100 healthy controls. CONCLUSION: The c.2261insG (p.E95X) mutation of the TCOF1 gene probably underlies the disease in the patient. Genetic testing can facilitate diagnosis and genetic counseling for families affected with TCS. PMID- 30298496 TI - [Clinical and genetic analysis of a family affected by progressive familial intraphepatic cholestasis type 3]. AB - OBJECTIVE: To explore the clinical and genetic characteristics of a family affected by genetic cholestasis. METHODS: Clinical data of the patient was collected. Targeted exome sequencing was carried out to detect the pathogenic mutations. The results were confirmed by Sanger sequencing. RESULTS: The patient, a 5-year-old boy, presented with severe cholestatic cirrhosis. Genetic analysis revealed that he has carried compound heterozygous mutations c.1006-2A>G and c.3580C>T (p.R1194X) of the ABCB4 gene, which were inherited from his father and mother, respectively. By structural prediction, the mutation c.3580C>T can give rise to a truncated multi-drug resistance protein 3 (MDR3). CONCLUSION: The patient was diagnosed with progressive familial intrahepatic cholestasis type 3 (PFIC-3) based on clinical and molecular findings. Detection of novel mutations of the ABCB4 gene has provided valuable clues for the diagnosis and genetic counseling. PMID- 30298497 TI - [A case of congenital bile acid synthesis disorder type 2 and literature review]. AB - OBJECTIVE: To summarize the clinical features, biochemical change and genetic mutations of a neonate with congenital bile acid synthesis disorder type 2. METHODS: Clinical features, blood biochemical index, gene analysis and treatment of the patient were reviewed. RESULTS: The patient presented with the symptoms of jaundice 3 days after birth but without skin itching. Pale stool was noted. Subsequently, he presented with hepatomegaly, blood coagulation disorders, left cochlear nerve damage, liver cirrhosis and remarkable growth retardation. Serum biochemistries showed that bilirubin and transaminase were elevated, while gamma GT and total bile acid was normal. Abdominal ultrasonography indicated decline of gallbladder contraction. Cholangiography showed normal extra- and intrahepatic bile ducts and patent biliary tract. Liver biopsy showed intrahepatic cholestasis. Gene testing has identified a homozygous mutation in AKR1D1 gene. CONCLUSION: Congenital bile acid synthesis disorder should be suspected when a neonate has presented with jaundice, elevated bilirubin and transaminase, normal or reduced TBA and gamma -GT. Genetic testing and urine mass spectrometry analysis can diagnose congenital bile acid synthesis disorder. Early therapy is crucial to patients with congenital bile acid synthesis disorder. PMID- 30298498 TI - [Clinical and genetic analysis of a case with atypical ethyl malonate encephalopathy]. AB - OBJECTIVE: To delineate the clinical and genetic characteristics of a girl featuring motor retardation, language retardation and regression, and light persisting diarrhea. METHODS: The patient was clinically examined and tested by tandem mass spectrometry and next generation sequencing. RESULTS: The proband could not stand and walk alone, and had light persisting diarrhea. She manifested language development retardation and regression. Laboratory tests were all normal, but the screening of metabolic disorders for urine and blood showed deficiency of short chain coenzyme A dehydrogenase due to elevated ethylmalonic acid and butyryl carnitine. By next generation sequencing, two compound heterozygous mutations of the ETHE1 gene, c.2T>A and c.488G>A, were discovered in the proband, which were respectively inherited from her father and mother. Bioinformatics analysis predicted both mutations to be pathogenic. The patient was diagnosed with ethylmalonic encephalopathy. Vitamin B1, B2, Coenzyme Q10, and L-carnitine were prescribed. The patient deteriorated and required liver transplantation at 4-year-1-month. CONCLUSION: Based on the clinical and genetic analysis, the proband was diagnosed with ethylmalonic encephalopathy caused by ETHE1 gene mutation. Next generation sequencing has provided a powerful tool for the diagnosis of such disorders. PMID- 30298499 TI - [A classic case with maple syrup urine disease caused by compound heterozygous mutations of BCKDHB gene]. AB - OBJECTIVE: To explore the genetic etiology of a patient with classic maple syrup urine disease (MSUD). METHODS: Next-generation sequencing (NGS) was used to screen the exons of BCKDHA, BCKDHB, DBT and DLD genes. Suspected mutations were verified by Sanger sequencing. Bioinformatic analysis was carried out to predict the influence of mutations on the protein structure and function. RESULTS: NGS and Sanger sequencing have detected a c.550delT mutation in exon 5 of the BCKDHB gene in the mother and a c.1046G>A mutation in exon 10 of the BCKDHB gene in the father, while no mutation was found with BCKDHA, DBT and DLD genes. Among these, the c.550delT is a novel mutation. Bioinformatic analysis suggested that the two mutations both located in a highly conserved region and may decrease the activity of branched-chain alpha-ketoacid dehydrogenase complex through alternation of its structure. CONCLUSION: The compound heterozygous mutations c.550delT and c.1046G>A of the BCKDHB gene probably underlie the clinical manifestations of the patient with classic MSUD. PMID- 30298500 TI - [Analysis of SPTA1 gene mutations in a patient with hereditary elliptocytosis]. AB - OBJECTIVE: To detect disease-causing mutations in a patient with hereditary elliptocytosis. METHODS: Sodium dodecyl sulfate polyacrylamide gel electropheresis (SDS-PAGE) was used to identify the type of erythrocyte membrane protein defect. Potential mutations of the exons and adjacent introns of relevant genes were analyzed by Sanger sequencing. RESULTS: SDS-PAGE has failed to detect any difference between the patient and healthy controls. However, Sanger sequencing has detected three mutations in the SPTA1 gene in the patient, which included c.5077A>C (p.Lys1693Gln) missense mutation in exon 36, c.5572C>G (p.Leu1858Val) missense mutation in exon 40, and a IVS45nt-12C>T in intron 45. The father and grandmother of the patient were both heterozygous for c.5077A>C mutation, while her mother was heterozygous for c.5572C>G and IVS45nt-12C>T mutations. CONCLUSION: The hereditary elliptocytosis in the patient may be attributed to the synergistic action of c.5077A>C, c.5572C>G and IVS45nt-12C>T mutations of the SPTA1 gene. PMID- 30298501 TI - [Clinical features and genetic analysis of a case with Coffin-Siris syndrome]. AB - OBJECTIVE: To explore the clinical features and genomic abnormality of a patient with Coffin-Siris syndrome. METHODS: Microdeletion and microduplication were detected with chromosomal microarray analysis (CMA) and verified with real-time quantitative PCR. RESULTS: The patient, a 6-month-old boy, featured global development delay, thick eyebrows, low frontal hairline, long eyelash, flat nasal bridge, hypotonia, difficulty in turning over, over stretching of head, and hypoplatic nails. He could not stand stability or actively grasp. He also has characteristics of rickets. Chromosome karyotype of the patient was normal. Genomic analysis has detected a 1.3 Mb deletion in 6q25.3 region encompassing the ARID1B gene. Neither of his parents was found to harbor the same deletion. CONCLUSION: The 6q25.3 microdeletion probably underlies the Coffin-Siris syndrome in this patient, and rickets may be part of its clinical spectrum. PMID- 30298502 TI - [Prenatal diagnosis and genetic analysis of a fetus with 2p13.3-p12 microdeletion]. AB - OBJECTIVE: To provide prenatal diagnosis for a pregnant woman with a history of Williams-Beuren syndrome pregnancy. METHODS: The karyotypes of the fetus and his parents were analyzed with routine G-banding. Their genomic DNA was also analyzed with array comparative genomic hybridization (aCGH). RESULTS: No karyotypic abnormality was detected for the fetus and his parents. aCGH has identified a de novo 5.09 Mb deletion at 2p13.3-p12 in the fetus. CONCLUSION: The 2p13.3-p12 microdeletion carried by the fetus was de novo. As it has involved dosage sensitive genes SPR and DCTN1, the deletion is probably pathogenic. PMID- 30298503 TI - [Identification of a novel duplication of Xq13.1 in a case with floppy infant syndrome with SNP-array]. AB - OBJECTIVE: To explore the candidate disease causing gene for a case with floppy infant syndrome (FIS). METHODS: Single nucleotide polymorphism array (SNP array) was used for analyzing the whole genome copy number mutations in the proband. Multiple PCR combined with denaturing high performance liquid chromatography (DHPLC) was employed to verify the suspected mutations in the proband and his family members. RESULTS: A large duplication arr [hg19] Xq13.1: 67 987 646-73 805 828, which spans approximately 5.818182 Mb and encompasses 66 known genes, was identified in the proband. The multiple PCR-DHPLC assay confirmed duplication of HDAC8, PHKA1, TAF1, DLG3, KIF4A, IGBP1, PJA1 and SLC16A2 genes in the proband. His mother and grandmother both had duplication of the above genes in one X chromosome, but his aunt had not. CONCLUSION: The large Xq13.1 duplication identified by the SNP array probably underlies the FIS in this family. For its high-throughput, high resolution and capacity of automation, SNP array has provided a first line method for the genetic testing for infants featuring developmental delay with unknown reason, mental retardation, autism, multiple malformation and FIS. PMID- 30298504 TI - [Genetic analysis of a fetus with partial 18p tetraploidy syndrome]. AB - OBJECTIVE: To analyze a fetus with abnormal cardiac ultrasound by using various techniques and explore its genotype-phenotype correlation. METHODS: Lymphocytes derived from umbilical cord blood sample were subjected to G-banding analysis. Short tandem repeats quantitative fluorescence PCR (STR-QF-PCR) was used for analysis of fetal DNA as an auxiliary test. Low-coverage whole genome sequencing (WGS) was used to detect chromosomal deletion/duplication which exceeded 100 kb in size. RESULTS: The karyotype of the fetus was 47,XN,+mar. As detected by STR QF-PCR, the copy number of GATA178F11 locus on chromosome 18 was 4, and the duplicated fragment was derived from the mother. WGS suggested that the fetus to be 46,XN,dup(18p11.21p11.32).seq [GRCh37/hg19](10 001-15 378 887)* 4, with the duplicated fragment spanning approximately 15.38 Mb. CONCLUSION: The cardiac malformation of the fetus may be attributed to the partial duplication of chromosome 18p. Combined cytogenetic and molecular methods can facilitate prenatal detection of genetic abnormalities. PMID- 30298505 TI - [Phenotypic and genotypic analysis of 45 cases with Hemoglobin Q-Thailand]. AB - OBJECTIVE: To explore hematological and molecular characteristics of Hemoglobin Q Thailand in Huizhou area of Guangdong Province. METHODS: A total of 34 977 samples were screened by capillary and agarose gel electrophoresis. Samples suspected with HbQ strips were subjected to blood cell count and DNA sequencing. Twenty three common mutations associated with alpha- and beta-thalassemia were identified by liquid phase chip and diversion hybridization technique. RESULTS: The carrier rate of Hb Q-Thailand in Huizhou area was 0.13%. Pedigree analysis indicated that the Hb Q-Thailand allele is linked with a leftward single a-globin gene deletion (-alpha4.2). Hematological index (HGB, MCV, MCH, HbA, HbA2, HbQ) of 45 heterozygous carriers of Hb Q-Thailand were (130.25+/-17.37) g/L, (79.81+/ 4.97) fl, (26.38+/-1.48) pg, (71.37+/-5.07)%, (1.65+/-0.45)%, (26.87+/-4.95)%, respectively. A statistical difference was also found in their hematological index of HbA and HbA2 compared with 408 heterozygous carriers of -alpha4.2 mutation (P<0.05). CONCLUSION: Hb Q-Thailand has a high detection rate in Huizhou area. The allele is mainly in a heterozygous status and linked with -alpha4.2. The Hb Q strip can be detected by hemoglobin electrophoresis. When combined with other types of thalassemia, the heterozygotes will show unique hematological parameters. PMID- 30298506 TI - [Analysis of clinical features of patients with de novo primary acute myeloid leukemia and various chromosomal karyotypes]. AB - OBJECTIVE: To explore clinical features of patients with de novo primary acute myeloid leukemia (AML) and various chromosomal karyotypes. METHODS: Clinical data of 144 patients was retrospectively reviewed. The patients included 76 males and 68 females, with a median age of 41.5 years and inter-quartile ranging from 25.25 to 53.75 years. Based on cytogenetic prognostic stratification criteria, the patients were divided into good prognosis (GP group, 55 cases), moderate prognosis (MP group, 71 cases) and poor prognosis (PP group, 18 cases). The PP group was further divided into complex karyotype (CK group, 15 cases) and non complex karyotype (NCK group, 3 cases), or monosomy karyotype (MK group, 9 cases) and non-monosomy karyotype (NMK group, 9 cases). All data was analyzed by Student's test, Chi-square test or rank sum test based on the type of data. RESULTS: Comparing the clinical data between GP, MP and PP group, there were statistically significant differences in the components of the FAB classification and the mutation of NPM1 and CSF1R genes (chi2=125.444, 15.538 and 7.049, P<0.05). Compared with the NCK group, the CK group had significantly fewer primitive cells in their bone marrow and fewer platelet in their peripheral blood (t=-3.059 and -2.830, P<0.05). Compared with the NMK group, the MK group had significantly fewer red blood cells and lower hemoglobin in their peripheral blood (t=-3.764 and -3.384, P<0.05). CONCLUSION: For patient with de novo primary AML, those with GP chromosome are more likely to be M2b or M3 with recurrent genetic abnormalities, the MP ones are more likely to be M1, M2a or M5 of AML-NOS based on WHO classification and associate with NPM1 mutations, while the PP ones are more likely to be M2a of AML-NOS based on WHO classification and M5 with recurrent genetic abnormalities and associate with CSF1R mutations. Compared with those with NCK chromosomes, the CK ones have lower proportion of primitive cells in their bone marrow and fewer platelets in peripheral blood. Compared with those with NMK chromosomes, the MK ones have lower red blood cell count and hemoglobin in their peripheral blood. PMID- 30298507 TI - [Preliminary analysis of genetics and clinical features of patients with acute myeloid leukemia and near-tetraploid/tetraploidy karyotype]. AB - OBJECTIVE: To explore the genetic and clinical features of patients with acute myeloid leukemia (AML) and near-tetraploidy/tetraploidy (NT/T) karyotype. METHODS: Cytogenetic findings of 1836 cases of primary AML were retrospectively analyzed. Karyotypes of the identified cases were confirmed by fluorescence in situ hybridization (FISH). Clinical data including gender, age, morphology, immunophenotype, genetics, and prognosis were reviewed. RESULTS: Nine male and two female patients with NT/T were identified with a median age of 63 years. Microscopically, the patients were characterized by large blasts and irregular nuclear contours. All patients expressed CD34, and nine of them expressed HLA-DR. Ten patients had complete remission during the first course of treatment. One patient showed primary drug resistance. CONCLUSION: NT/T AML primarily occurs in elder males and has a characteristic morphology and genetics. The prognosis is better than AML patients with complex karyotypes. PMID- 30298508 TI - [Association of ZP4 gene polymorphism with primary open-angle glaucoma in an ethnic Chinese population from Sichuan province]. AB - OBJECTIVE: To assess the association of single nucleotide polymorphisms (SNP) rs547984, rs540782, rs693421 and rs2499601 of Zona Pellucida Glycoprotein 4 (ZP4) gene with primary open-angle glaucoma (POAG) among ethnic Han Chinese from Sichuan Province. METHODS: A dye terminator-based SNaPshot method was used to genotype 336 patients with POAG and 768 healthy controls. RESULTS: No significant difference was detected in allelic frequencies of rs547984, rs540782, rs693421 and rs2499601 between the two groups (P>0.05). Haplotypic analysis showed a significant difference in G-G-A-G haplotype formed by the 4 SNPs between the POAG and the control groups (P<0.05). CONCLUSION: ZP4 gene SNPs rs547984, rs540782, rs693421, rs2499601 are not associated with POAG among ethnic Hans from Sichuan. PMID- 30298509 TI - [Molecular basis of an individual with CisAB subtype of ABO blood group]. AB - OBJECTIVE: To explore the molecular basis for an individual with CisAB subtype of the ABO blood group. METHODS: ABO antigen and serum antibody of the proband were detected with a serological method. Exons 5 to 7 of the ABO gene were amplified with PCR and sequenced bidirectionally. Allele-specific amplification for exon 6 to 7 was also carried out. RESULTS: The proband was assigned as a CisAB phenotype based on his serological characteristics. Heterozygous variations including 220C/T, 261G/del, 297A/G, 467C/T, 646A/T, 681A/G, 771C/T, 803G/C, 829A/G and 1009A/G of the ABO gene were identified through direct sequencing, which was assigned as CisAB01var/O02 genotype. Allele-specific amplification indicated that the proband carried an O02 allele and a CisAB01var allele. Compared with A102, the CisAB01var allele has two nucleotide substitutions at 803G>C and 1009A>G, which resulted in replacement of amino acid Gly by Ala at position 268 and Arg by Gly at position 337. CONCLUSION: The CisAB subtype was identified with 803G>C and 1009A>G variants in the alpha1,3-N-acetyl-galactosaminyltransferase gene compared with that of the A102 allele. PMID- 30298510 TI - [Analysis of a 389 T>C variant of alpha-1,3-N-acetylgalactoseaminotransferase gene]. AB - OBJECTIVE: To study the effect of a 389T>C variant in the alpha-1,3-N acetylgalactosaminyltransferase gene on the expression of A antigen by molecular genetic analysis of an individual with Ax subtype of ABO variant. METHODS: Serological assays were carried out to identify the ABO blood group of the proband. Exons 6 and 7 of the ABO gene were amplified with PCR and directly sequenced. Following identification of the heterozygote site, specific primers were used to determine the haplotype of the ABO gene. RESULTS: Weak A antigen was detected on red blood cells from the proband. And anti-A and anti-B antibodies were detected in the serum. DNA sequencing has identified heterozygous 261delG and 389T/C variants in exons 6 and 7. By haplotype analysis, two alleles Ax22 and O01 were found. Compared with that of A101, the Ax22 allele had a nucleotide change (T to C) at position 389, which resulted in an amino acid substitution (L130P). CONCLUSION: T>C at nt389 of the alpha-1,3-N-acetylgalactosaminyl transferase gene can result in significant reduction of A antigen activity. PMID- 30298511 TI - [Polymorphisms of MICA gene and their linkage disequilibrium with HLA-B among ethnic Han Chinese from Shenzhen]. AB - OBJECTIVE: To study the distribution of MICA alleles among ethnic Han Chinese blood donors from Shenzhen and their linkage disequilibrium with HLA-B gene. METHODS: For 143 randomly selected blood donors, the MICA and HLA-B alleles were determined with a PCR-sequence based typing (SBT) method. Allelic frequency, haplotypic diversity and linkage disequilibrium were analyzed with a Pypop software. RESULTS: Thirteen MICA and 35 HLA-B alleles were identified among the 143 blood donors, among which MICA*008:01 had the highest frequency (76/286), whilst MICA*008:01-HLA-B*40:01 and MICA*010-HLA-B*46:01 were the most common haplotypes. No novel allele was identified. CONCLUSION: The allele frequencies, haplotype diversities and linkage disequilibrium parameters under a high resolution can facilitate further studies and applications of the MICA and HLA-B genes. PMID- 30298512 TI - [Role of NRXN-NLGN-SHANK pathway gene variations in the pathogenesis of autism spectrum disorders]. AB - Autism spectrum disorders (ASDs) comprise a group of common neurodevelopmental disorders whose pathogenesis remains unclear. More than 100 genes have been associated with ASDs, some of which have shown to play important roles in the development and function of synapses, a crucial step of information transmission between neurons. Studies have found abnormalities in synaptic transmission, density, and structures in the brains of autistic patients. NRXN-NLGN-SHANK pathway has been associated with synaptic function of the brain, and its primary role is to regulate synaptic formation, elimination, plasticity and maturation. Genes including NRXN, NLGN, SHANK, and PSD95 are involved in the NRXN-NLGN-SHANK pathway. Mutations of such genes may lead to dysfunction of the pathway and ASDs related phenotypes found in patients and animal models. This paper has provided a review for the research progress made on the mutations of NRXN-NLGN-SHANK pathway related genes and their roles in the pathogenesis of ASDs. PMID- 30298513 TI - [Roles of exosomes in Parkinson's disease and amyotrophic lateral sclerosis]. AB - Exosomes, as a kind of extracellular vesicles generated by inward budding of the endosomes to form multi-vesicular bodies (MVBs), are secreted into the extracellular milieu and the systemic circulation thereafter. By endocytosis, direct fusion or receptor-ligand interactions, exosomes can interact with receptor cells and involve in various pathophysiological processes. Accumulating evidence have indicated that exosomes may play crucial roles in the pathogenesis of many neurodegenerative diseases including Parkinson's disease (PD), Huntington's disease (HD), Alzheimer disease (AD) and amyotrophic lateral sclerosis (ALS). In this paper, the roles of exosomes in the pathogenesis, diagnosis and treatment of PD and ALS are reviewed. PMID- 30298515 TI - Label-free quantitative proteomic analysis of human periodontal ligament stem cells by high-resolution mass spectrometry. AB - BACKGROUND AND OBJECTIVES: Proteome analysis of periodontal ligament stem cells (PDLSCs) could be used to study the function of PDL tissue. We used a label-free quantitative proteomic technique to investigate differentially expressed proteins (DEPs) in human PDLSCs (hPDLSCs) compared to human bone marrow mesenchymal stem cells (hBMSCs) and identify proteins specific to hPDLSCs. MATERIAL AND METHODS: hPDLSCs (n = 3) and hBMSCs (n = 3) were cultured and harvested for protein extraction and trypsin digestion. The proteomes of both cell types were analyzed by nano-liquid chromatography/tandem mass spectrometry. DEPs in hPDLSCs compared to hBMSCs were detected by label-free quantification and evaluated through signal transduction pathway and gene ontology (GO) analysis. RESULTS: In total, 690 and 771 proteins were identified from hPDLSCs and hBMSCs, of which 561 proteins were in common and 124 DEPs were found between hPDLSCs and hBMSCs. Fifty-eight proteins were expressed at significantly higher levels in hPDLSCs, whereas 66 proteins were expressed at lower levels compared to hBMSCs. The more highly expressed proteins were associated with translation and initiating protein synthesis, and lower expressed proteins were related to cell aging and metabolic processes. Proteins unique to hPDLSCs and hBMSCs were associated with translation and metabolic processes, respectively. CONCLUSION: Our results demonstrate evidence of distinct differences in protein expression between hPDLSCs and hBMSCs by using label-free quantitative proteomic analysis which was the first attempt in this field. DEPs included previously reported hPDLSC marker proteins and novel marker candidates, such as microtubule-associated protein, CTP synthase 1 and stathmin, which could be the markers for developing periodontal disease diagnostics and therapies. PMID- 30298514 TI - Macroscopic features of scurvy in human skeletal remains: A literature synthesis and diagnostic guide. AB - The past two decades have seen a proliferation in bioarchaeological literature on the identification of scurvy, a disease caused by chronic vitamin C deficiency, in ancient human remains. This condition is one of the few nutritional deficiencies that can result in diagnostic osseous lesions. Scurvy is associated with low dietary diversity and its identification in human skeletal remains can provide important contextual information on subsistence strategy, resource allocation, and human-environmental interactions in past populations. A large and robust methodological body of work on the paleopathology of scurvy exists. However, the diagnostic criteria for this disease employed by bioarchaeologists have not always been uniform. Here we draw from previous research on the skeletal manifestations of scurvy in adult and juvenile human skeletal remains and propose a weighted diagnostic system for its identification that takes into account the pathophysiology of the disease, soft tissue anatomy, and clinical research. Using a sample of individuals from the prehistoric Atacama Desert in Northern Chile, we also provide a practical example of how diagnostic value might be assigned to skeletal lesions of the disease that have not been previously described in the literature. PMID- 30298516 TI - Positron emission tomography (PET) and magnetic resonance imaging (MRI) for assessing tumour resectability in advanced epithelial ovarian/fallopian tube/primary peritoneal cancer. AB - BACKGROUND: Ovarian cancer is the leading cause of death from gynaecological cancer in developed countries. Surgery and chemotherapy are considered its mainstay of treatment and the completeness of surgery is a major prognostic factor for survival in these women. Currently, computed tomography (CT) is used to preoperatively assess tumour resectability. If considered feasible, women will be scheduled for primary debulking surgery (i.e. surgical efforts to remove the bulk of tumour with the aim of leaving no visible (macroscopic) tumour). If primary debulking is not considered feasible (i.e. the tumour load is too extensive), women will receive neoadjuvant chemotherapy to reduce tumour load and subsequently undergo (interval) surgery. However, CT is imperfect in assessing tumour resectability, so additional imaging modalities can be considered to optimise treatment selection. OBJECTIVES: To assess the diagnostic accuracy of fluorodeoxyglucose-18 (FDG) PET/CT, conventional and diffusion-weighted (DW) MRI as replacement or add-on to abdominal CT, for assessing tumour resectability at primary debulking surgery in women with stage III to IV epithelial ovarian/fallopian tube/primary peritoneal cancer. SEARCH METHODS: We searched MEDLINE and Embase (OVID) for potential eligible studies (1946 to 23 February 2017). Additionally, ClinicalTrials.gov, WHO-ICTRP and the reference list of all relevant studies were searched. SELECTION CRITERIA: Diagnostic accuracy studies addressing the accuracy of preoperative FDG-PET/CT, conventional or DW-MRI on assessing tumour resectability in women with advanced stage (III to IV) epithelial ovarian/fallopian tube/primary peritoneal cancer who are scheduled to undergo primary debulking surgery. DATA COLLECTION AND ANALYSIS: Two authors independently screened titles and abstracts for relevance and inclusion, extracted data and performed methodological quality assessment using QUADAS-2. The limited number of studies did not permit meta-analyses. MAIN RESULTS: Five studies (544 participants) were included in the analysis. All studies performed the index test as replacement of abdominal CT. Two studies (366 participants) addressed the accuracy of FDG-PET/CT for assessing incomplete debulking with residual disease of any size (> 0 cm) with sensitivities of 1.0 (95% CI 0.54 to 1.0) and 0.66 (95% CI 0.60 to 0.73) and specificities of 1.0 (95% CI 0.80 to 1.0) and 0.88 (95% CI 0.80 to 0.93), respectively (low- and moderate-certainty evidence). Three studies (178 participants) investigated MRI for different target conditions, of which two investigated DW-MRI and one conventional MRI. The first study showed that DW-MRI determines incomplete debulking with residual disease of any size with a sensitivity of 0.94 (95% CI 0.83 to 0.99) and a specificity of 0.98 (95% CI 0.88 to 1.00) (low- and moderate-certainty evidence). For abdominal CT, the sensitivity for assessing incomplete debulking was 0.66 (95% CI 0.52 to 0.78) and the specificity 0.77 (95% CI 0.63 to 0.87) (low- and low-certainty evidence). The second study reported a sensitivity of DW-MRI of 0.75 (95% CI 0.35 to 0.97) and a specificity of 0.96 (95% CI 0.80 to 1.00) (very low-certainty evidence) for assessing incomplete debulking with residual disease > 1 cm. In the last study, the sensitivity for assessing incomplete debulking with residual disease of > 2 cm on conventional MRI was 0.91 (95% CI 0.59 to 1.00) and the specificity 0.97 (95% CI 0.87 to 1.00) (very low-certainty evidence). Overall, the certainty of evidence was very low to moderate (according to GRADE), mainly due to small sample sizes and imprecision. AUTHORS' CONCLUSIONS: Studies suggested a high specificity and moderate sensitivity for FDG-PET/CT and MRI to assess macroscopic incomplete debulking. However, the certainty of the evidence was insufficient to advise routine addition of FDG-PET/CT or MRI to clinical practice..In a research setting, adding an alternative imaging method could be considered for women identified as suitable for primary debulking by abdominal CT, in an attempt to filter out false-negatives (i.e. debulking, feasible based on abdominal CT, unfeasible at actual surgery). PMID- 30298517 TI - Anti-alcohol liver disease effect of Gentianae macrophyllae extract through MAPK/JNK/p38 pathway. AB - OBJECTIVES: The hepatoprotective effect of Gentianae macrophyllae root extract (GME) on alcoholic liver disease (ALD) was evaluated through ethanol induced ALD animal model. METHODS: Mice were randomly divided into control normal group (10 mice), ethanol-induced ALD model group (10 mice) and GME plus ethanol group (30 mice). Mice in model group were given intragastric administration with 50% (v/v) ethanol aqueous solution (200 MUl for each) once daily for 19 days. Mice in control normal group received equal volumes of water. Mice in GME plus ethanol group were given intragastric administration with 50% (v/v) ethanol aqueous solution (200 MUl for each) once daily at 10:00 a.m., after 1 h, mice in GME group sequentially were treated with 20, 40 and 100 mg/kg of GME by gastric gavage for 19 days. the average food and water consumed by the mice in every group were recorded every 2 days and body weight of every mouse in every group was measured every 2 days. KEY FINDINGS: Results showed that GME significantly improved alcohol induced liver injury in a dose-dependent manner. The impaired hepatic tissue structure was repaired and the collagen deposition declined after GME administration. Meanwhile, the level of malonaldehyde (MDA), Aspartate transaminase (AST) and alanine transaminase (ALT) (indicators of liver damage) in blood serum were significantly controlled by GME with a dose-dependent manner, moreover, body weight and liver index were also improved after administration of GME. Pro-inflammatory cytokines including MCP-1, TNF-alpha, IL-1 and IL-6 were detected through RT-PCR and ELISA in experiment and GME can significantly inhibit the expression of TNF-alpha, IL-1 and IL-6 but have no effect on MCP-1. In order to explore the mechanism of GME on ALD, MAPKs pathway was examined and results indicated that GME attenuated ALD through inhibiting the phosphorylation of JNK and P38 and further suppressing the initiation of inflammation. CONCLUSIONS: GME attenuated ALD through inhibiting the phosphorylation of JNK and P38 and further suppressing the initiation of inflammation. PMID- 30298518 TI - Implicit motives and basic psychological needs. AB - The present article starts with discussing similarities and differences between conceptualizations of human needs in self-determination theory (SDT; Deci & Ryan [1985], Intrinsic motivation and self-determination in human behavior; Deci & Ryan [2000], Nebraska symposium on motivation: Perspectives on motivation) and motive disposition theory (MDT; McClelland, Human motivation, 1985). The second section focuses on the two-process model of psychological needs (Sheldon [2011], Psychological Review, 118: 552), which aims to integrate the two approaches, whereas the third section highlights some aspects of both theories that are still decoupled or even contradictory, but nevertheless still have a high potential to be linked. These three aspects are (a) the noncorresponding concepts of implicit power motive (MDT) and basic need for autonomy (SDT); (b) the differentiation of needs into hope and fear components, which is theoretically embedded in MDT, but not in SDT; and (c) MDT researchers' differentiation into an implicit and explicit motivational system, which is not included in SDT. Particularly, the last section highlights the potential for areas in which further integration is possible, which provides a foundation for comprehensive and exciting research on human motivation. PMID- 30298519 TI - Development of non-governmental organisation-academic partnership to tackle rabies in Africa and Asia. AB - Rabies kills approximately 60,000 people each year, mainly in sub-Saharan Africa and Asia, of which 40% of victims are less than 15 years old. Once clinical signs develop, the disease is almost invariably fatal. Globally, rabies has been estimated to cause 3?7 million disability-adjusted life years and $8?6B in economic losses annually. The vast majority of human rabies cases are caused by bites from rabies infected dogs. Despite this loss of human life and resultant economic and societal costs, rabies can be prevented in both humans and dogs by vaccination. This has been demonstrated in many countries, notably in Central and South America, where large-scale, high coverage mass dog vaccination programmes have dramatically reduced the incidence of rabies. Even in parts of Africa and Asia, projects have shown that rabies can be eliminated locally. Nevertheless, rabies remains an important cause of mortality in many sub-Saharan and Asian countries. The reasons why some countries have been able to effectively eliminate rabies whereas others have not are complex and often impossible to definitively identify; commonly cited explanations include political, economic, logistical and societal barriers. PMID- 30298520 TI - Diversity of oil yield, fatty acids, tocopherols, tocotrienols, and sterols in the seeds of 19 interspecific grapes crosses. AB - BACKGROUND: The seeds of Vitis vinifera grapes have been studied extensively but knowledge about the interspecific crosses of other Vitis species (e.g. V. vinifera, V. amurensis, V. rupestris, V. riparia, and V. labruska) is very limited. RESULTS: The oil yields recovered from the grape seeds ranged between 7 and 160 g kg-1 dw. The main fatty acids were linoleic (72.5-83.1%), oleic (6.2 15.5%), and palmitic (5.4-13.2%), which together constituted 92.8-97.1% of the total detected fatty acids. The total concentration of tocopherol (T) and tocotrienol (T3) homologues was between 0.785 and 9.033 g kg-1 oil. The concentration of sterols varied significantly and ranged between 2.912 and 105.962 g kg-1 oil. The beta-sitosterol constituted 68.2-86.3% of the total content of sterols. The oil yield in grape seeds significantly correlated with the oleic acid, alpha-linolenic acid, alpha-T, alpha-T3, gamma-T3, campesterol, Delta5-stigmasterol, beta-sitosterol, and total Ts + T3 s and sterols. CONCLUSION: The present study demonstrated that seed oil recovered from different interspecific Vitis crosses is a rich source of minor lipophilic bioactive compounds, especially genotypes with low oil content. They can be used to enrich plant oils that are poor in tocotrienols and/or phytosterols without changing the fatty acid composition of main oil, due to low enrichment quantities (micro blends).

AB - BACKGROUND: Low-fat or non-fat yoghurts are popular nowadays. However, their texture is not good and they show considerable syneresis with time. The aim of this research was to evaluate the effect of the application of transglutaminase (TG) to low-fat yoghurt to determine if similar sensory properties to those of full-fat yoghurt can be obtained. Methods of adding TG (prior or simultaneous with fermentation), dose, and TG origin were evaluated. Correlations between sensory and physicochemical parameters were assessed. RESULTS: The results showed no significant differences between TG addition methods in terms of the quantitative and qualitative sensory attributes studied. Simultaneous addition of TG was preferred to speed up the process. A dose of 1 U g-1 was selected as optimal. Few differences were detected due to the origin of the TG. They were not significant although some differences were observed in terms of density, bitterness, and syneresis compared with low and full-fat yoghurts. CONCLUSION: The results showed that sensory parameters cannot be associated with only one physicochemical parameter in yoghurt evaluation. Transglutaminase can be used as a substitute for stabilizers in the production of low-fat yoghurt, maintaining good sensory properties and avoiding initial syneresis.

AB - Post-thawing motility of spermatozoon, which is directly correlated with the integrity of mitochondrion, is the main parameter for evaluation of respective cryopreservation treatments. In this review, we describe our model of mitochondrial apparatus of spermatozoa and behaviour of this apparatus during cryopreservation. This model shows why a priori the mitochondrial apparatus of the human spermatozoon is expected to be more cryo-stable than the mitochondrial apparatus of the fish spermatozoon. Negative changes of mitochondrial membrane potential are a good indicator of the functional normality of mammalian and fish spermatozoa. It is concluded that the cryostability of mitochondrial membranes of fish spermatozoa is lower than that of human spermatozoa, and protocols for effective cryopreservation of fish spermatozoa can be extrapolated to human spermatozoa. It is also provided a biological explanation for why cryoprotectant free vitrification for human ejaculates is better than conventional freezing and vitrification with cryoprotectants. This review also includes a description of the various technologies of vitrification of human and fish spermatozoa. For cryobiological investigations, we propose to evaluate the fish spermatozoon as a suitable representative model of the human spermatozoon.

AB - PURPOSE: To develop an electrical property tomography reconstruction method that achieves improvements over standard method by redesigning the Laplacian kernel. THEORY AND METHODS: A decomposition property of the governing PET equation shows the possibility of redesigning the Laplacian kernel for conductivity reconstruction. Hence, the discrete Laplacian operator used for electrical property tomography reconstruction is redesigned to have a Gaussian-like envelope, which enables manipulation of the spatial and spectral response. The characteristics of the proposed kernel are investigated through numerical simulations and in vivo brain experiments. RESULTS: The proposed method reduces textured noise, which hampers observing features of the conductivity image. Furthermore, the proposed scheme can mitigate the propagation of local phase error such as flow-induced phase. By doing so, the proposed method can recover feature information in conductivity (or resistivity) images. Lastly, the proposed kernel can be extended to other electrical property tomography reconstructions, improving the quality of images. CONCLUSION: An alternative design of the Laplacian kernel for conductivity imaging has been developed to mitigate the textured noise and the propagation of local phase artifact. PMID- 30298525 TI - Copula selection models for non-Gaussian outcomes that are missing not at random. AB - Missing not at random (MNAR) data pose key challenges for statistical inference because the substantive model of interest is typically not identifiable without imposing further (eg, distributional) assumptions. Selection models have been routinely used for handling MNAR by jointly modeling the outcome and selection variables and typically assuming that these follow a bivariate normal distribution. Recent studies have advocated parametric selection approaches, for example, estimated by multiple imputation and maximum likelihood, that are more robust to departures from the normality assumption compared with those assuming that nonresponse and outcome are jointly normally distributed. However, the proposed methods have been mostly restricted to a specific joint distribution (eg, bivariate t-distribution). This paper discusses a flexible copula-based selection approach (which accommodates a wide range of non-Gaussian outcome distributions and offers great flexibility in the choice of functional form specifications for both the outcome and selection equations) and proposes a flexible imputation procedure that generates plausible imputed values from the copula selection model. A simulation study characterizes the relative performance of the copula model compared with the most commonly used selection models for estimating average treatment effects with MNAR data. We illustrate the methods in the REFLUX study, which evaluates the effect of laparoscopic surgery on long-term quality of life in patients with reflux disease. We provide software code for implementing the proposed copula framework using the R package GJRM. PMID- 30298526 TI - Association between self-reported bruxism and anger and frustration. AB - BACKGROUND: Even though bruxism has been shown to be associated with several psychological factors, few studies have been performed on its relationships with anger and frustration. OBJECTIVE: This study aimed to determine the association between self-reported awake and sleep bruxism and anger and frustration. METHODS: In this longitudinal observational study, 55 healthy adult participants with "possible" bruxism reported their experienced level of bruxism and several psychosocial factors and lifestyle factors for 28 consecutive days using a personal logbook. The logbook consisted of a daily diary and a weekly questionnaire composed of Dutch versions of validated questionnaires. The primary outcome data were analysed using multiple regression models. RESULTS: An increase in SB of 1 unit (on a scale ranging from 1 to 10) was associated with an increase in the anger-scale of 0.03 units, and the frustration-scale of 0.04 units. However, the random intercepts were 0.22 for anger and 0.19 for frustration, meaning that there were major differences between individuals. For awake bruxism (AB), the effects were an increase of 0.04 for anger with a random intercept of 0.21 and an increase of 0.03 for frustration with a random intercept of 0.06. The effects of anger and frustration on both SB and AB were not statistically significant. CONCLUSION: The association between anger and frustration and self reported bruxism is small on group level. In individual cases, anger and frustration and self-reported bruxism may be co-existent. PMID- 30298527 TI - From Nose to Gut - The Role of the Microbiome in Neurological Disease. AB - Inflammation and neurodegeneration are key features of many chronic neurological diseases, yet the causative mechanisms underlying these processes are poorly understood. There has been mounting interest in the role of the human microbiome in modulating the inflammatory milieu of the central nervous system in health and disease. To date, most research has focussed on a gut-brain axis, with other mucosal surfaces being relatively neglected. We herein take the novel approach of comprehensively reviewing the roles of the microbiome across several key mucosal interfaces - the nose, mouth, lung, and gut - in health and in Parkinson's disease (PD), Alzheimer's disease (AD) and multiple sclerosis (MS). This review systematically appraises the anatomical and microbiological landscape of each mucosal surface in health and disease before considering relevant mechanisms that may influence the initiation and progression of PD, AD, and MS. The cumulative effects of dysbiosis from the nose to the gut may contribute significantly to neurological disease through a wide variety of mechanisms, including direct translocation of bacteria and their products, and modulation of systemic or central nervous system-specific immunity. This remains an understudied and exciting area for future research and may lead to the development of therapeutic targets for chronic neurological disease. This article is protected by copyright.

AB - Reticular pseudodrusen (RPD), also known as subretinal drusenoid deposits, represent a morphological change to the retina distinct from other subtypes of drusen by being located above the level of the retinal pigment epithelium. Although they can infrequently appear in individuals with no other apparent pathology, their highest rates of occurrence are in association with age-related macular degeneration (AMD), for which they hold clinical significance by being highly correlated with end-stage disease sub-types, choroidal neovascularisation and geographic atrophy. Reticular pseudodrusen are also found in other diseases, most notably Sorsby's fundus dystrophy, pseudoxanthoma elasticum and acquired vitelliform lesions. They are found more frequently in females, with increased age and more commonly bilaterally than unilaterally. Increased risk of RPD formation is conveyed by genetic variants known to increase risk of AMD development, including complement factor H, age-related maculopathy susceptibility 2, and high-temperature requirement A serine peptidase 1; however, to date, no genetic factor has been found to predispose to RPD independent of those that carry risks for AMD. They have typical features visible on multimodal imaging, identifiable either as single lesions or more commonly in yellowish white net-like patterns on colour fundus photography and are particularly distinguishable using spectral domain optical coherence tomography, fundus auto fluorescence, and near infrared reflectance imaging. On histological examination, RPD have been shown to have distinct compositions in comparison to typical drusen, suggesting different pathways of pathogenesis. Although their aetiology remains unclear, presence of opsin within lesions, a high topographic association with areas of highest rod-photoreceptor concentration and functional deficits most pronounced within the scotopic range, has implicated rod photoreceptor dysfunction as a component of RPD.

PMID- 30298529 TI - The eMERGE genotype set of 83,717 subjects imputed to ~40 million variants genome wide and association with the herpes zoster medical record phenotype. AB - The Electronic Medical Records and Genomics (eMERGE) network is a network of medical centers with electronic medical records linked to existing biorepository samples for genomic discovery and genomic medicine research. The network sought to unify the genetic results from 78 Illumina and Affymetrix genotype array batches from 12 contributing medical centers for joint association analysis of 83,717 human participants. In this report, we describe the imputation of eMERGE results and methods to create the unified imputed merged set of genome-wide variant genotype data. We imputed the data using the Michigan Imputation Server, which provides a missing single-nucleotide variant genotype imputation service using the minimac3 imputation algorithm with the Haplotype Reference Consortium genotype reference set. We describe the quality control and filtering steps used in the generation of this data set and suggest generalizable quality thresholds for imputation and phenotype association studies. To test the merged imputed genotype set, we replicated a previously reported chromosome 6 HLA-B herpes zoster (shingles) association and discovered a novel zoster-associated loci in an epigenetic binding site near the terminus of chromosome 3 (3p29). PMID- 30298531 TI - Evaluation of a new matrix-assisted laser desorption/ionization time-of-flight mass spectrometry system for the identification of yeast isolation. AB - BACKGROUND: Currently, three commercial in vitro diagnostic matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) systems are widely used in clinical laboratories. The ASTA MicroIDSys system (ASTA Inc, South Korea) is a newly developed MALDI-TOF MS system used for the identification of pathogenic microorganisms. In the present study, we assessed the performance of the ASTA MALDI-TOF MS system for the identification of pathogenic yeast from clinical samples. METHODS: We tested 284 clinical yeast isolates from various clinical specimens using ASTA MALDI-TOF MS, and the results were compared with those using molecular sequencing of the ITS or D1-D2 regions of rDNA and biochemical assays. RESULTS: A total of 284 isolates were tested and found to be distributed across 14 species including Candida albicans (n = 100) and other yeast species (n = 184). ASTA MALDI-TOF MS correctly identified 95.1% (270/284) of the yeast species compared to molecular sequencing. Among them, 262 isolates showed acceptable MALDI-TOF MS scores (>=140), and 98.1% (257/262) isolates were identified correctly. In addition, among 22 isolates with a MALDI-TOF MS score <140, 59.1% (13/22) of the isolates showed concordance with molecular typing at the species level. Clustering analysis revealed the effectiveness of the new MALDI-TOF MS system for the identification of yeast species. CONCLUSIONS: ASTA MALDI-TOF MS showed high accuracy in the identification of yeast species; it involves facile sample preparation and extraction procedures. ASTA MALDI-TOF MS is expected to be useful for yeast identification in clinical microbiology laboratories due to its reliability and cost-effectiveness. PMID- 30298532 TI - Maternal and perinatal outcomes after elective induction of labor at 39 weeks in uncomplicated singleton pregnancy: a meta-analysis. AB - OBJECTIVE: The rate of maternal and perinatal complications increases after 39 weeks' gestation in both unselected and complicated pregnancies. The aim of this study was to synthesize quantitatively the available evidence on the effect of elective induction of labor at 39 weeks on the risk of Cesarean section, and on maternal and perinatal outcomes. METHODS: PubMed, US Registry of Clinical Trials, SCOPUS and CENTRAL databases were searched from inception to August 2018. Additionally, the references of retrieved articles were searched. Eligible studies were randomized controlled trials of singleton uncomplicated pregnancies in which participants were randomized between 39 + 0 and 39 + 6 gestational weeks to either induction of labor or expectant management. The risk of bias of individual studies was assessed using the Cochrane Risk of Bias Tool. The overall quality of evidence was assessed according to the GRADE guideline. Primary outcomes included Cesarean section, maternal death and admission to the neonatal intensive care unit (NICU). Secondary outcomes included operative delivery, Grade 3/4 perineal laceration, postpartum hemorrhage, maternal infection, hypertensive disease of pregnancy, maternal thrombotic events, length of maternal hospital stay, neonatal death, need for neonatal respiratory support, cerebral palsy, length of stay in NICU and length of neonatal hospital stay. Pooled risk ratios (RRs) were calculated using random-effects models. RESULTS: The meta-analysis included five studies (7261 cases). Induction of labor was associated with a decreased risk for Cesarean section (moderate quality of evidence; RR 0.86 (95% CI, 0.78-0.94); I2 = 0.1%), maternal hypertension (moderate quality of evidence; RR 0.65 (95% CI, 0.57-0.75); I2 = 0%) and neonatal respiratory support (moderate quality of evidence; RR 0.73 (95% CI, 0.58-0.95); I2 = 0%). Neonates born after induction weighed, on average, 81 g (95% CI, 63-100 g) less than those born after expectant management. No significant effects were found for the other outcomes with the available data. The main limitation of our analysis was that the majority of data were derived from a single large study. A second limitation arose from the open-label design of the studies, which may theoretically have affected the readiness of the attending clinician to resort to Cesarean section. CONCLUSIONS: Elective induction of labor in uncomplicated singleton pregnancy at 39 weeks' gestation is not associated with maternal or perinatal complications and may reduce the need for Cesarean section, risk of hypertensive disease of pregnancy and need for neonatal respiratory support.

AB - Zinc oxide (ZnO) supplied at pharmacological dosage in diets of weaned piglets improves growth performance. However, it causes environmental contamination and induces bacterial antibiotic resistance, yet this practice is debated. The effects on gut microbiota and integrity in weaned piglets of conventional ZnO at nutritional and pharmacological dosage (110 and 2,400 mg/kg Zn, respectively) were compared to an alternative ZnO source at 110 and 220 mg/kg Zn. Each of the four treatments was applied to four pens (two piglets/pen; weaning age, 20 days) for 15 days, and piglets were sampled on day 15 to determine indices of gut integrity. Feeding conventional ZnO at 2,400 mg/kg Zn reduced coliforms and Escherichia coli in distal small intestine as compared to conventional ZnO at 110 mg/kg (-1.7 and -1.4 log10 cfu/g, respectively), whereas the alternative ZnO reduced only coliforms, irrespective of dosage (-1.6 to -1.7 log10 cfu/g). Transepithelial electrical resistance of distal small intestinal mucosa was higher for pigs fed the alternative ZnO source as compared with groups fed 110 mg/kg Zn of conventional ZnO, in line with a trend for higher gene expression of claudin-1 and zona occludens-1. Interestingly, the alternative ZnO source at 110 and 220 mg/kg Zn increased intestinal alkaline phosphatase gene transcript as compared to conventional ZnO at 110 mg/kg Zn, whereas the alternative ZnO source at 110 mg/kg Zn exhibited higher Zn concentrations in mucosa (2,520 MUg/g) as compared to conventional ZnO at 110 mg/kg Zn (1,211 MUg/g). However, assessing alkaline phosphatase activity, no significant effects were found. In conclusion, the alternative ZnO reduced digesta Enterobacteriaceae numbers and improved gut integrity, albeit similar or better, depending on the dosage, to the effects of pharmacological dosage of conventional ZnO. PMID- 30298534 TI - Information needs in day-to-day operations management in hospital units: A cross sectional national survey. AB - AIM: To describe and compare shift leaders' important information needs by profession, unit, time of day and type of hospital. BACKGROUND: Professionals responsible for care provision in hospital units make ad hoc decisions about available resources to meet patient care needs but, currently, much effort is needed to obtain the necessary information to support decision making. METHODS: This survey was carried out in nine randomly chosen hospitals in Finland. Nurses and physicians responsible for day-to-day operations were eligible to participate (N = 873). The response rate was 65% (n = 570, including 453 nurses and 111 physicians). Data were collected in 2015-2016 using the Hospital Shift Leaders' Information Needs Questionnaire with 114 information need items. RESULTS: Shift leaders reported many real-time information needs. Nurses' important information needs concerned patients, personnel, and materials, and physicians' needs focused on patient care. Large mean differences existed in the needs between nurses and physicians, and imaging units when compared to other units. CONCLUSION: Real-time information systems for shift leaders should consider the needs of different users to support shared situational awareness and operational intelligence. IMPLICATIONS FOR NURSING MANAGEMENT: The important information-need items identified here may be used in designing and developing information systems that better support shift leaders' work in hospitals. PMID- 30298535 TI - In vitro functional characterization of the novel DHH mutations p.(Asn337Lysfs*24) and p.(Glu212Lys) associated with gonadal dysgenesis. AB - In humans, mutations of Desert Hedgehog gene (DHH) have been described in patients with 46,XY gonadal dysgenesis (GD), associated or not with polyneuropathy. In this study, we describe two patients diagnosed with GD, both harboring novel DHH compound heterozygous mutations p.[Tyr176*];[Asn337Lysfs*24] and p.[Tyr176*];[Glu212Lys]. To investigate the functional consequences of p.(Asn337Lysfs*24) and p.(Glu212Lys) mutations, located within the C-terminal part of DHh on auto-processing, we performed in vitro cleavage assays of these proteins in comparison with Drosophila melanogaster Hedgehog (Hh). We found that p.(Glu212Lys) mutation retained 50% of its activity and led to a partially abolished DHh auto-processing. In contrast, p.(Asn337Lysfs*24) mutation resulted in a complete absence of auto-proteolysis. Furthermore, we found a different auto processing profile between Drosophila Hh and human DHh, which suggests differences in the processing mechanism between the two species. Review of the literature shows that proven polyneuropathy and GD is associated with complete disruption of DHh-N, whereas disruption of the DHh auto-processing is only described with GD. We propose a model that may explain the differences between Schwann and Leydig cell development by autocrine versus paracrine DHh signaling. To our knowledge, this is the first study investigating the effect of DHH mutations on DHh in vitro auto-processing.

A., Young, A. J., Burke T. A., & Hodgson, D. (2018). Inbreeding intensifies sex- and age-dependent disease in a wild mammal. Journal of Animal Ecology, 87, 1497-1499. https://doi.org/10.1111/1365-2656.12878 Increasing crossbreeding of relatives promotes inbreeding which, in turn, can cause a reduction in fitness and the emergence of a phenomenon known as inbreeding depression. Benton et al., used the badger (Meles meles)-Mycobacterium bovis model system to study the relationship between inbreeding, disease, ageing and sex. A link between multilocus homozygosity (general effect) and TB progression (measured as antibody response to infection) and between homozygosity at specific loci (local effect) and TB progression were established in this study, highlighting the importance of host genetic background in determining host disease outcomes, and thus on shaping disease dynamics in wild populations. Moreover, the authors demonstrated for the first time in a natural population that this positive association might be modulated by sex and age. In infected individuals, inbreeding only affects disease progression in adult females. PMID- 30298537 TI - Fabrication Method for a Mounting Jig and Cast Support for Mounting Complete Dentures.

PMID- 30298538 TI - Applying ambiguous loss theory to children of parents with an opioid use disorder. AB - PROBLEM: Opioid use disorder (OUD) has reached epidemic proportions in the United States. Children of parents with OUD are an unrepresented population, who often suffer consequences from their parent's substance abuse disorder. Such children may incur numerous psychosocial and physical losses. Without intervention, they are more likely to be diagnosed with a mental illness and/or substance use disorder (SUD). METHODS: This paper examines the experiences of children of parents with OUD using Boss's theory of ambiguous loss (AL) as a lens. FINDINGS: Children growing up with a parent who has an OUD experience AL through that parent's physical absence and psychological presence (e.g., the parent is out opioid-seeking or in rehab or jail) and psychological absence but physical presence (e.g., the parent is high or in withdrawal, or is preoccupied with obtaining opioids). Evidence supports the fact that OUDs affect parenting, produce changes in the parent-child relationship, and often impact child development. Interventions that are child-focused are lacking. CONCLUSIONS: The application of AL theory to this problem can enhance health professionals' understanding and need for developmentally specific interventions to care for this population. Interventions should focus on diminishing stigma and promoting psychosocial wellness and resiliency for children of parents with an OUD. PMID- 30298539 TI - Prospective evaluation of the limitations of near-infrared imaging in detecting axillary sentinel lymph nodes in primary breast cancer. AB - We compared the performance of near-infrared imaging using indocyanine green (ICG) with the radioisotope (ISO) method to detect sentinel lymph nodes (SLNs) in breast cancer, to analyze predictive factors for negative ICG identification. The study included 122 patients who underwent sentinel lymph node biopsy (SLNB) using the combined ISO and ICG technique for primary breast cancer. We assessed the putative association between pathologic/clinical variables and ICG failure to detect SLNs. The ISO identification rate was 96.7% and ICG identification 81.9%. Overweight patients or presence of macrometastasis in SLNB were associated with the risk of ICG failing to detect SLNs (P = 0.02). PMID- 30298540 TI - Prognostic significance of genetic biomarkers in isocitrate dehydrogenase-wild type lower-grade glioma: the need to further stratify this tumor entity - a meta analysis. AB - The clinical outcomes of isocitrate dehydrogenase-wild-type (IDH-wt) lower-grade glioma (LGG) have been the subject of debate for some time. In this meta analysis, we aimed to assess the prognostic values of several known genetic markers (e.g. TERT promoter mutation, H3F3A mutation, CDKN2A loss) in this tumor group. Four electronic databases, including PubMed, Scopus, Web of Science and Virtual Health Library, were searched for relevant articles. Pooled hazard ratio (HR) and corresponding 95% confidence interval (CI) for overall survival were calculated using a random-effect model weighted by an inverse variance method. A total of 11 studies were finally selected from 2274 articles for meta-analyses. Several genetic alterations were demonstrated to have a negative impact on prognosis of IDH-wt LGGs, specifically TERT promoter mutation (HR, 1.96; 95% CI, 1.42-2.70), H3F3A mutation (HR, 3.21; 95% CI, 1.86-5.55) and EGFR amplification (HR, 1.67; 95% CI, 1.02-2.74). However, CDKN loss, ATRX mutation and coexisting gain of chromosome 7/loss of chromosome 10 showed no clinical significance in this glioma entity. Our study results demonstrated that IDH-wt LGGs are heterogeneous in clinical outcome and not all tumors have a poor prognosis. The presence of TERT promoter mutation, H3F3A mutation and EGFR amplification showed negative prognostic impacts in this tumor entity. These genetic events can be used to better stratify patient outcomes. PMID- 30298541 TI - Progestogen for preventing miscarriage in women with recurrent miscarriage of unclear etiology. AB - BACKGROUND: Progesterone, a female sex hormone, is known to induce secretory changes in the lining of the uterus essential for successful implantation of a fertilized egg. It has been suggested that a causative factor in many cases of miscarriage may be inadequate secretion of progesterone. Therefore, clinicians use progestogens (drugs that interact with the progesterone receptors), beginning in the first trimester of pregnancy, in an attempt to prevent spontaneous miscarriage. This is an update of a review, last published in 2013. OBJECTIVES: To assess the efficacy and safety of progestogens as a preventative therapy against recurrent miscarriage. SEARCH METHODS: For this update, we searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (6 July 2017) and reference lists from relevant articles, attempting to contact trial authors where necessary, and contacted experts in the field for unpublished works. SELECTION CRITERIA: Randomized or quasi-randomized controlled trials comparing progestogens with placebo or no treatment given in an effort to prevent miscarriage. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Two reviewers assessed the quality of the evidence using the GRADE approach. MAIN RESULTS: Thirteen trials (2556 women) met the inclusion criteria. Nine of the included trials compared treatment with placebo and the remaining four trials compared progestogen administration with no treatment. The trials were a mix of multicenter and single-center trials, conducted in Egypt, India, Jordan, UK and USA. In six trials women had had three or more consecutive miscarriages and in seven trials women had suffered two or more consecutive miscarriages. Routes, dosage and duration of progestogen treatment varied across the trials. The majority of trials were at low risk of bias for most domains. Eleven trials (2359 women) contributed data to the analyses.The meta-analysis of all women, suggests that there is probably a reduction in the number of miscarriages for women given progestogen supplementation compared to placebo/controls (average risk ratio (RR) 0.69, 95% confidence interval (CI) 0.51 to 0.92, 11 trials, 2359 women, moderate quality evidence). A subgroup analysis comparing placebo-controlled versus non placebo-controlled trials and different routes of administration showed no differences between subgroups for miscarriage. However, there appears to be a subgroup difference for miscarriage between women with three or more prior miscarriages compared to women with two or more miscarriages, with a more pronounced effect in women with three or more prior miscarriages. However, it should be noted that there was high heterogeneity in the subgroup of women with three or more prior miscarriages.None of the trials reported on any secondary maternal outcomes, including severity of morning sickness, thromboembolic events, depression, admission to a special care unit, or subsequent fertility.There was probably a slight benefit for women receiving progestogen seen in the outcome of live birth rate (RR 1.11, 95% CI 1.00 to 1.24, 7 trials, 2086 women, moderate quality evidence). While the rate of preterm birth is probably reduced for women receiving progestogen, this outcome was mainly driven by one trial and thus should be interpreted with great caution (RR 0.59, 95% CI 0.39 to 0.89, 5 trials, 811 women, moderate-quality evidence). No clear differences were seen for women receiving progestogen for the other secondary outcomes of neonatal death or fetal genital abnormalities. A possible reduction in stillbirth was seen, but again this outcome was driven mainly by one trial and should be interpreted with caution (RR 0.38, 95% CI 0.24 to 0.58, 3 trials, 1199 women). There may be little or no difference in the rate of low birthweight and trials did not report on the secondary child outcomes of teratogenic effects or admission to a special care unit. AUTHORS' CONCLUSIONS: For women with unexplained recurrent miscarriages, supplementation with progestogen therapy probably reduces the rate of miscarriage in subsequent pregnancies. PMID- 30298542 TI - A rare case of disseminated Mycobacterium avium complex with colitis in a renal transplant recipient. AB - Mycobacterium avium complex (MAC) colitis is a rare complication of immunosuppression in solid organ transplant (SOT) recipients. Here, we describe a case of disseminated MAC infection with colitis following renal transplantation. Despite common pathways of immunosuppression, SOT recipients and human immunodeficiency virus (HIV)-infected patients differ in their typical presentations of MAC infection. Intestinal infections have been more commonly reported in HIV-infected patients than in SOT recipients. The explanation for this difference may be related to HIV's targeted effects on the CD4+ T-cell reservoir in gut-associated lymphoid tissue. PMID- 30298543 TI - Selective Cholecystectomy: using an evidence-based prediction model to plan for cholecystectomy. AB - BACKGROUND: Symptomatic gall stones are treated safely and efficiently with laparoscopic cholecystectomy. Conversion to open cholecystectomy may be associated with adverse outcomes. Accurate prediction of conversion should decrease the incidence of conversion and improve patient care. METHODS: The recent literature on conversion at laparoscopic cholecystectomy is reviewed to identify robust prediction models that are both internally and externally validated. RESULTS: Two prediction models are identified which meet these criteria. CONCLUSIONS: The Cairns Prediction Model using nomograms, is an easily applied tool predicting conversion, which is presently in use. Routine use of this tool should decrease conversion, and improve the process of patient consent.

AB - OBJECTIVES: We sought to determine the 1-year clinical follow-up in patients treated with the thin strut (71 MUm) bioabsorbable polymer-coated sirolimus eluting stent (BP-SES) vs durable coating everolimus eluting stent (DP-EES) in daily clinical routine. BACKGROUND: Presence of durable polymers may be associated with late/very late stent thrombosis occurrence and the need for prolonged dual antiplatelet therapy. Bioabsorbable polymers may facilitate stent healing, thus enhancing clinical safety. METHODS: Interventional Cardiology Network Registry is a prospective, multicenter, observational registry of 21,400 consecutive patients treated with PCI since 2010. We analyzed 4,670 patients treated with either a BP-SES (ALEX, Balton, Poland) or DP-EES (XIENCE, Abbott, USA) with available 1-year clinical follow-up using propensity-score matching. Outcomes included target vessel revascularization (TVR) as efficacy outcome and all cause death, myocardial infarction (MI), and definite/probable stent thrombosis as safety outcomes. RESULTS: After propensity score matching, 1,649 patients treated with BP-SES and 1,649 patients treated with DP-EES were selected. Procedural and clinical characteristics were similar between both groups. There was no significant difference between tested groups in in-hospital mortality. One-year follow-up demonstrated comparable efficacy outcome, TVR (BP SES 5.9% vs DP-EES 4.6% P = 0.45), as well as comparable safety outcomes, all cause death, MI and definite/probable stent thrombosis. CONCLUSIONS: In this multicenter registry, the BP-SES thin strut biodegradable polymer-coated sirolimus-eluting stent demonstrated comparable clinical outcomes at 1-year after implantation to the DP-EES. These data support the relative safety and efficacy of DP-SES in a broad range of patients undergoing percutaneous coronary intervention.

PMID- 30298547 TI - Background field removal for susceptibility mapping of human brain with large susceptibility variations. AB - PURPOSE: In quantitative susceptibility mapping (QSM) of human brain, the background field induced by air-tissue interface varies significantly with respect to the rotation angle between the head and the static field, which may result in substantial error in the estimated magnetic susceptibility values. The goal of this study was to develop a strategy to better remove such orientation dependent background field. METHODS: An improved background field removal method is proposed based on the sophisticated harmonic artifact reduction for phase data using a region adaptive kernel (R-SHARP), named iRSHARP. It uses a spatially weighted spherical Gaussian kernel exploiting the amplitude, gradient, and wrap count of the phase map. The method was validated using both numerical simulations and in vivo human brain data at multiple head orientations. Performance was compared with the variable kernel (V-SHARP) and R-SHARP methods. RESULTS: The proposed iRSHARP method showed improved background removal over R-SHARP while cutting the computational time in half. As compared to V-SHARP and R-SHARP, the iRSHARP generated local field and susceptibility maps showed fewer artifacts in regions of large susceptibility variations, and for the in vivo human brain, the susceptibilities of the deep gray matter nuclei were consistent with the in vivo gold-standard "Calculation of Susceptibility through Multiple Orientation Sampling" (COSMOS) values. CONCLUSION: iRSHARP can remove the orientation dependent background field effectively. Using iRSHARP, the paranasal sinus regions can be preserved in the brain mask and the brain integrity was conserved, which may facilitate further data analysis and clinical application. PMID- 30298549 TI - Improved facial affect recognition in patients with first-episode psychosis. AB - AIM: The present study aimed at assessing whether impaired facial affect recognition (FAR) in patients with first-episode psychosis (FEP) would improve after a brief intervention targeting FAR specifically. METHODS: Thirty-five outpatients and 38 healthy controls were administered an intervention which involved training to recognize emotional information, conveyed by changes in facial features. Using a pre- and post-intervention design, two measurements of FAR were conducted using an experimental procedure with alternative sets of stimuli. RESULTS: We found improved overall FAR performance in both participant groups with marked effects in recognizing anger, disgust and fear. Patients' post intervention performance was comparable to healthy participants' baseline performance. CONCLUSIONS: The present improvement in facial affects recognition in FEP patients, despite only somewhat impaired, emphasizes the importance of early targeted interventions for FAR in psychosis. Further research is needed to assess whether this improvement will generalize to global social functioning. PMID- 30298548 TI - Antibiofilm activity substances derived from coral symbiotic bacterial extract inhibit biofouling by the model strain Pseudomonas aeruginosa PAO1. AB - The mitigation of biofouling has received significant research attention, with particular focus on non-toxic and sustainable strategies. Here, we investigated quorum sensing inhibitor (QSI) bacteria as a means of controlling biofouling in a laboratory-scale system. Approximately, 200 strains were isolated from coral (Pocillopora damicornis) and screened for their ability to inhibit quorum sensing (QS). Approximately, 15% of the isolates exhibited QSI activity, and a typical coral symbiotic bacterium, H12-Vibrio alginolyticus, was selected in order for us to investigate quorum sensing inhibitory activity further. Confocal microscopy revealed that V. alginolyticus extract inhibited biofilm formation from Pseudomonas aeruginosa PAO1. In addition, the secondary metabolites of V. alginolyticus inhibited PAO1 virulence phenotypes by downregulating motility ability, elastase activity and rhamnolipid production. NMR and MS spectrometry suggested that the potential bioactive compound involved was rhodamine isothiocyanate. Quantitative real-time PCR indicated that the bacterial extract induced a significant downregulation of QS regulatory genes (lasB, lasI, lasR, rhlI, rhlR) and virulence-related genes (pqsA, pqsR). The possible mechanism underlying the action of rhodamine isothiocyanate analogue involves the disruption of the las and/or rhl system of PAO1. Our results highlight coral microbes as a bioresource pool for developing QS inhibitors and identifying novel antifouling agents. PMID- 30298550 TI - CRDSAT Generated by pCARGHO: A New Efficient Lectin-Based Affinity Tag Method for Safe, Simple, and Low-Cost Protein Purification. AB - Purification of recombinant proteins remains a bottleneck for downstream processing. The authors engineered a new galectin 3 truncated form (CRDSAT ), functionally and structurally characterized, with preserved solubility and lectinic activity. Taking advantage of these properties, the authors designed an expression vector (pCARGHO), suitable for CRDSAT -tagged protein expression in prokaryotes. CRDSAT binds to lactose-Sepharose with a high specificity and facilitates solubilization of fusion proteins. This tag is structurally stable and can be easily removed from fusion proteins using TEV protease. Furthermore, due to their basic isoelectric point (pI), CRDSAT , and TEV are efficiently eliminated using cationic exchange chromatography. When pI of the protein of interest (POI) and CRDSAT are close, other chromatographic methods are successfully tested. Using CRDSAT tag, the authors purified several proteins from prokaryote and eukaryote origin and demonstrated as examples, the preservation of both Escherichia coli Thioredoxin 1 and human CDC25Bcd activities. Overall, yields of proteins obtained after tag removal are about 5-50 mg per litre of bacterial culture. Our purification method displays various advantages described herein that may greatly interest academic laboratories, biotechnology, and pharmaceutical companies. PMID- 30298551 TI - Power and sample size requirements for GEE analyses of cluster randomized crossover trials. AB - The cluster randomized crossover design has been proposed to improve efficiency over the traditional parallel cluster randomized design, which often involves a limited number of clusters. In recent years, the cluster randomized crossover design has been increasingly used to evaluate the effectiveness of health care policy or programs, and the interest often lies in quantifying the population averaged intervention effect. In this paper, we consider the two-treatment two period crossover design, and develop sample size procedures for continuous and binary outcomes corresponding to a population-averaged model estimated by generalized estimating equations, accounting for both within-period and interperiod correlations. In particular, we show that the required sample size depends on the correlation parameters through an eigenvalue of the within-cluster correlation matrix for continuous outcomes and through two distinct eigenvalues of the correlation matrix for binary outcomes. We demonstrate that the empirical power corresponds well with the predicted power by the proposed formulae for as few as eight clusters, when outcomes are analyzed using the matrix-adjusted estimating equations for the correlation parameters concurrently with a suitable bias-corrected sandwich variance estimator. PMID- 30298553 TI - Efficiently activated epsilon-poly-L-lysine production by multiple antibiotic resistance mutations and acidic pH shock optimization in Streptomyces albulus. AB - epsilon-Poly-L-lysine (epsilon-PL) is a food additive produced by Streptomyces and is widely used in many countries. Working with Streptomyces albulus FEEL-1, we established a method to activate epsilon-PL synthesis by successive introduction of multiple antibiotic-resistance mutations. Sextuple mutant R6 was finally developed by screening for resistance to six antibiotics and produced 4.41 g/L of epsilon-PL in a shake flask, which is 2.75-fold higher than the level produced by the parent strain. In a previous study, we constructed a double resistance mutant, SG-31, with high epsilon-PL production of 3.83 g/L and 59.50 g/L in a shake flask and 5-L bioreactor, respectively. However, we found that R6 did not show obvious advantages in fed-batch fermentation when compared with SG 31. For further activation of epsilon-PL synthesis ability, we optimized the fermentation process by using an effective acidic pH shock strategy, by which R6 synthetized 70.3 g/L of epsilon-PL, 2.79-fold and 1.18-fold greater than that synthetized by FEEL-1 and SG-31, respectively. To the best of our knowledge, this is the highest reported epsilon-PL production to date. This epsilon-PL overproduction may be due to the result of R99P and Q856H mutations in ribosomal protein S12 and RNA polymerase, respectively, which may be responsible for the increased transcription of the epsilon-poly-lysine synthetase gene (pls) and key enzyme activities in the Lys synthesis metabolic pathway. Consequently, epsilon PL synthetase activity, intracellular ATP, and Lys concentrations were improved and directly contributed to epsilon-PL overproduction. This study combined ribosome engineering, high-throughput screening, and targeted strategy optimization to accelerate epsilon-PL production and probe the fermentation characteristics of hyperyield mutants. The information presented here may be useful for other natural products produced by Streptomyces. PMID- 30298552 TI - Efficacy of fluid loading as a countermeasure to the hemodynamic and hormonal changes of 28-h head-down bed rest. AB - After exposure to microgravity, or head-down bed rest (HDBR), fluid loading is often used with the intent of increasing plasma volume and maintaining mean arterial pressure during orthostatic stress. Nine men (aged 18-32 years) underwent three randomized trials with lower body negative pressure (LBNP) before and after: (1) 4-h of sitting with fluid loading (1 g sodium chloride/125 mL of water starting 2.5-h before LBNP), (2) 28-h of 6-degree HDBR without fluid loading, and (3) 28-h of 6-degree HDBR with fluid loading. LBNP was progressive from 0 to -40 mmHg. After 28-h HDBR, fluid loading did not protect against the loss of plasma volume (-280 +/- 64 mL without fluid loading, -207 +/- 86 with fluid loading, P = 0.472) nor did it protect against a drop of mean arterial pressure (P = 0.017) during LBNP (Post-28 h HDBR response from 0 to -40 mmHg LBNP: 88 +/- 4 to 85 +/- 4 mmHg without fluid loading and 93 +/- 4 to 88 +/- 5 mmHg with fluid loading, P = 0.557 between trials). However, fluid loading did protect against the loss of stroke volume index and central venous pressure observed after 28-h HDBR. Fluid loading also attenuated the increase of angiotensin II seen after 28-h HDBR and throughout the LBNP protocol (Post-28 h HDBR response from 0 to -40 mmHg LBNP: 16.6 +/- 3.4 to 23.7 +/- 5.0 pg/mL without fluid loading and 6.1 +/- 0.8 to 12.2 +/- 2.3 pg/mL with fluid loading, P < 0.001 between trials). Our results indicate that fluid loading did not protect against plasma volume loss due to HDBR or change blood pressure responses to LBNP. However, changes in central venous pressure, stroke volume and fluid regulatory hormones could potentially influence longer duration studies and those with more severe orthostatic stress. PMID- 30298554 TI - Annotating transcriptional effects of genetic variants in disease relevant tissue: Transcriptome-wide allelic imbalance in osteoarthritic cartilage. AB - OBJECTIVES: Multiple osteoarthritis (OA) susceptibility single nucleotide polymorphisms (SNPs) mark imbalanced expression of positional genes in articular cartilage, reflected by unequally expressed alleles among heterozygotes (allelic imbalance, AI). Here, we explored the articular cartilage transcriptome from OA patients for AI events to identify putative disease driving genetic variation. METHODS: AI was assessed in N=42 preserved and N=5 lesioned OA cartilage samples (RAAK-study) for which RNA sequencing data was available. Hereto, the count fraction of the alternative allele among the alternative and reference allele together (phi) was determined for heterozygous individuals. A meta-analysis per SNP was performed to generate a meta-phi and P-value per SNP with a multiple testing correcting false discovery rate (FDR). To further validate AI events, we explored them as function of multiple additional OA features. RESULTS: In total 2070 SNPs were observed that consistently marked AI of 1031 unique genes in articular cartilage. Of these 49 genes were found significantly differentially expressed (0.5>FC>2, FDR<0.05) between preserved and paired lesioned cartilage and 21 genes previously reported to confer susceptibility for OA and/or related phenotypes. Moreover, notable highly significant AI SNPs in the CRLF1, WWP2, and RPS3 genes were identified that were related to multiple OA features. CONCLUSION: A framework and resulting datasets for researchers in the OA research field to probe for disease relevant genetic variation that affects respective gene expression in the disease's pivotal affected tissue and likely including putative novel compelling OA risk genes such as CRLF1, WWP2, and RPS3.

PMID- 30298556 TI - Is dietary melatonin supplementation a viable adjunctive therapy for chronic periodontitis?-A randomized controlled clinical trial. AB - BACKGROUND AND OBJECTIVE: Melatonin is synthesized naturally by pineal gland and responsible for regulation of sleep/waking cycle. It showed appreciated anti inflammatory and antioxidant properties. The aim of this randomized clinical trial (RCT) was to assess the additive effect of melatonin supplementation in insomniac individuals with generalized chronic periodontitis (gCP) after scaling and root planing (SRP). MATERIAL AND METHODS: Seventy-four gCP patients with primary insomnia participated in this 6-month RCT and randomized into two groups. Melatonin group included 38 patients who were subjected to SRP with a 2-month regimen of 10 mg oral melatonin capsule once daily before bedtime. In the control group, SRP was performed for 36 participants provided with matching placebo capsules. The primary treatment outcome was the measurement of clinical attachment level gain (CAL gain) after 3 and 6 months of therapy, whereas the measurements of pocket depth reduction (PD reduction), bleeding on probing (BOP %), and the changes in salivary TNF-alpha levels and Athens insomnia scale (AIS) scores represented the secondary endpoints. RESULTS: Melatonin group showed significantly greater CAL gain and PD reduction measurements compared to the control group at 3 and 6 months of therapy, P < 0.01. Likewise, salivary TNF alpha levels and AIS scores were significantly lower in the melatonin group compared to placebo group. BOP% improved significantly in both groups without any difference. However, salivary TNF-alpha levels exhibited no correlation with other clinical variables in both melatonin and placebo groups. CONCLUSION: Daily dietary 10 mg of melatonin supplementation might serve as a viable adjunct to SRP that yielded significantly greater CAL gain and PD reduction and lower salivary TNF-alpha levels and AIS scores in gCP patients with primary insomnia.

AB - A cross-sectional observational study of 43 infants and 60 adult women was performed in South Africa to assess skin barrier (SB) function through noninvasive quantification of transepidermal water loss (TEWL) and skin surface hydration (SSH). TEWL and SSH improved with age and in anatomic locations with chronic environmental exposure in keeping with reported trends in other ethnicities. PMID- 30298557 TI - Offspring diet supersedes the transgenerational effects of parental diet in a specialist herbivore Neolema abbreviata under manipulated foliar nitrogen variability. AB - Diet quality influences organismal fitness within and across generations. For herbivorous insects, the transgenerational effects of diet remain relatively underexplored. Using a 3 * 3 * 2 factorial experiment, we evaluated how N enrichment in parental diets of Neolema abbreviata (Larcordaire) (Coleoptera: Chrysomelidae), a biological control agent for Tradescantia fluminensis Vell. (Commelinaceae), may influence life history and performance of F1 and F2 offspring under reciprocal experiments. We found limited transgenerational effects of foliar nitrogen variability among life-history traits in both larvae and adults. Larval weight gain and mortality were responsive to parental diet contrary to feeding damage, pupal weight and duration taken to pupate. There were significant parental diet * test interactions in larval feeding damage, weight gain, pupal weight and time to pupation. Generally, offspring from parents under high N plants performed better even under low N test plants. Adult traits including oviposition selection, feeding weight and longevity did not respond to the effects of parental diet nor its interaction with test diet as was the case in the larval stage. However, the main effects of test diet were more important in determining adult performance in both generations suggesting limited sensitivity to parental diet in the adult stage. Our results show conflicting responses to parental diet between larvae and adults of the same generation among an insect species with both actively feeding larval and adult life stages. These transgenerational effects, or lack thereof, may have implications on the field performance of N. abbrevita under heterogeneous nutritional landscapes. PMID- 30298558 TI - Evaluation of Flexural Strength of Different Denture Base Materials Reinforced with Different Nanoparticles. AB - PURPOSE: To evaluate the effect of adding Al2 O3 , SiO2 , and TiO2 nanoparticles in ratios of 1, 3, and 5 wt% to different acrylic resins on flexural strength. MATERIALS AND METHODS: A total of 210 specimens were prepared in 30 groups (n = 7/group) (Control, 1% Al2 O3 , 3% Al2 O3 , 5% Al2 O3 , 1% SiO2 , 3% SiO2 , 5% SiO2 , 1% TiO2 , 3% TiO2 , 5% TiO2 ). The specimens were polished with 200-, 400 , and 600-grit abrasive paper to provide a standard surface before testing and then suspended in distilled water for 30 days. Flexural strength was measured via three-point bending tests. Subsequently, SEM analysis was performed for one specimen from each group. Homogeneity of data was assessed by Kolmogov-Smirnov test followed by two-way ANOVA and Tukey HSD tests (alpha = 0.05). RESULTS: There was a significant increase in the flexural strength of polymethylmethacrylate (PMMA) after addition of 1% nanoparticles in both heat-polymerized and autopolymerized acrylic resins (p ? 0.05). The flexural strength values of the groups to which Al2 O3 and TiO2 nanoparticles were added exceeded those of the group with SiO2 addition (p ? 0.05). The electron microscopy images revealed that the nanoparticles were more homogeneously dispersed in PMMA with higher flexural strength. CONCLUSIONS: The mechanical properties of PMMA can be improved by the addition of nanoparticles to PMMA; however, the flexural strength values of PMMA decrease with the addition of nanoparticles at higher percentages (3-5%). Hence, the ideal filler ratio corresponds to 1%. PMID- 30298559 TI - Concept and practice of transradial 5 French percutaneous treatment of coronary bifurcation lesions. AB - OBJECTIVES: To assess the efficacy and safety of transradial 5 French percutaneous treatment of coronary bifurcations using conventional devices. BACKGROUND: Radial artery is smaller than femoral artery, and its size may potentially limit transradial intervention, especially when coronary anatomy is not known. METHODS: Patients with bifurcations lesions undergoing transradial 5 French ad hoc revascularization were treated according to provisional side branch (SB) stenting followed by the POT-SB dilation-final POT sequence. Only conventional devices were used. RESULTS: Overall, 80 patients (58 men, 65 +/- 10 years) were enrolled. True bifurcations accounted for 64% of cases, with the left anterior descending artery/diagonal branch being the most frequent bifurcation site (n = 37, 46%) and left main coronary artery bifurcation being treated in 6 (8%) patients. Angiographic success was achieved in 78 (97.5%) patients through a 5 French guiding catheter whereas in two cases, a 5-6 French guiding catheter upgrade was required to optimize SB treatment after the main bifurcation vessel have been secured. Overall, procedural success was achieved in all but one patient who had periprocedural necrosis following multivessel PCI. Another patient underwent target bifurcation revascularization because of a critical restenosis in a significant SB yielding an acute coronary syndrome five months after the index procedure. CONCLUSIONS: This study demonstrates the feasibility of transradial 5 French bifurcation intervention with nondedicated devices and preliminary supports its efficacy and safety over a wide range of bifurcation anatomy and complexity. PMID- 30298560 TI - Efficacy of ketoprofen lysine salt and paracetamol/acetaminophen to reduce pain during rapid maxillary expansion: A randomized controlled clinical trial. AB - BACKGROUND: Rapid maxillary expansion (RME) is an orthopaedic procedure indicated for a wide variety of clinical conditions. AIM: The aim of the study was to compare the effects of ketoprofen lysine salt (KLS) vs paracetamol/acetaminophen (P) on pain perception during RME. DESIGN: One hundred and fifty-one subjects (mean age 8.6 year) were enrolled in this prospective controlled clinical trial according to inclusion criteria: prepuberal stage of development, negative posterior transverse interarch discrepancy, non-concurrent use of other drugs. First phase: n.40 allocated to Group 1 used 40 mg of KLS, n.40 to Group 2 used 250 mg of P, n.36 to Group 3 as control group. Second phase: n.35 allocated to Group 4 used 40 mg ketoprofen lysine salt once a day for the first 3 days of activation. Pain experience was reported on a numeric rating scale (0-4) and a 100-mm visual analogue scale. Pain perception was tested with the Mann-Whitney test (P < 0.05). RESULTS: Pain perception was higher during the first 3 days of activation and it was described as mild to moderate. Group 1 experienced significantly less pain during the fourth, fifth, and sixth day (P < 0.05) compared with Group 2. Patients of the Group 4 reported significantly lower pain during the whole period of RME activation (P < 0.05). CONCLUSIONS: The perceived higher pain was reported during the second and third day of expansion. The analgesic effect of KLS is more effective than P during the fourth, fifth, and sixth day. The use of KLS during the first 3 days of activation seems to be able reducing pain during the whole active phase. PMID- 30298561 TI - Genetic diversity and antimicrobial resistance in Staphylococcus aureus and coagulase-negative Staphylococcus isolates from bovine mastitis in Minas Gerais, Brazil. AB - The aims of this study were to determine the antimicrobial susceptibility profile and genetic diversity of Staphylococcus spp. isolated from dairy cows in Minas Gerais, Brazil, and to assess the relationship among the isolates' susceptibility profiles and pulsed-field gel electrophoresis (PFGE) genotypes. Seventy-nine isolates were used, including S. aureus (n = 71) and coagulase-negative staphylococci (CoNS) (n = 8). Susceptibility to 12 antimicrobial agents was performed. All Staphylococcus spp. were subjected to PFGE. Staphylococcus aureus and CoNS isolates exhibited full susceptibility only to cephalothin. The greatest percentages of resistance among Staphylococcus spp. were observed to penicillins, folate pathway inhibitors, and tetracyclines. Twelve S. aureus and four CoNS were classified as multidrug resistance strains. Percentage of MRSA was also higher among CoNS (75%), compared to S. aureus isolates (2.81%). Adopting 100% of similarity, 34 different genotypes were identified. Association of minimum spanning tree (MST) analysis with data from municipalities, herds, methicillin resistant S. aureus (MRSA), and resistance patterns for all isolates did not show any clustering. However, a clustering pattern of bacterial species was observed. Results from this study indicate a high frequency of antimicrobial resistance, especially among CoNS, and a high genetic diversity among Staphylococcus spp. isolated from dairy cows with mastitis in Minas Gerais, Brazil.

PMID- 30298562 TI - Increased risk of recurrence in resected EGFR-positive pN0M0 invasive lung adenocarcinoma. AB - BACKGROUND: This study was conducted to evaluate the prognostic and recurrent impact of EGFR mutation status in resected pN0M0 lung adenocarcinoma with consideration of the histological subtype. METHODS: Following retrospective analysis of whole 474 consecutive pathological N0M0 lung adenocarcinoma patients, the prognostic significance of EGFR mutation status was evaluated in limited 394 subjects. Overall survival and recurrence-free interval (RFI) were estimated using the Kaplan-Meier method and compared using a log-rank test. Univariate and multivariate analyses were performed using Cox proportional hazard models. RESULTS: The five-year RFI was 85.7% and 93.3% for EGFR positive (n = 176) and negative (n = 218) cases, respectively (hazard ratio [HR] 1.992, 95% confidence interval [CI] 1.005-3.982; P = 0.048). Following the exclusion of specific subtypes free from recurrence or EGFR mutation (adenocarcinoma in situ, minimally invasive adenocarcinoma, and invasive mucinous adenocarcinoma), the five-year RFI was obviously poorer in EGFR positive compared to negative cases (80.7% and 92.1%, respectively; HR 2.163, 95% CI 1.055-4.341; P = 0.035). Multivariate analysis excluding the specific subtypes confirmed that male sex, age, current or Ex-smoking status, pleural invasion, and EGFR-positive status were independently associated with shorter RFI. No significant differences in five-year overall survival were found between the EGFR mutation positive and negative groups (88.7% and 93.7%, respectively; HR 1.630, 95% CI 0.787-3.432; P = 0.2). CONCLUSION: EGFR mutations are associated with recurrence in pN0M0 lung adenocarcinoma. EGFR mutation status and histological subtype should be considered when evaluating the risk of recurrence in resected lung adenocarcinoma patients. PMID- 30298564 TI - Multi-SKAT: General framework to test for rare-variant association with multiple phenotypes. AB - In genetic association analysis, a joint test of multiple distinct phenotypes can increase power to identify sets of trait-associated variants within genes or regions of interest. Existing multiphenotype tests for rare variants make specific assumptions about the patterns of association with underlying causal variants, and the violation of these assumptions can reduce power to detect association. Here, we develop a general framework for testing pleiotropic effects of rare variants on multiple continuous phenotypes using multivariate kernel regression (Multi-SKAT). Multi-SKAT models affect sizes of variants on the phenotypes through a kernel matrix and perform a variance component test of association. We show that many existing tests are equivalent to specific choices of kernel matrices with the Multi-SKAT framework. To increase power of detecting association across tests with different kernel matrices, we developed a fast and accurate approximation of the significance of the minimum observed P value across tests. To account for related individuals, our framework uses random effects for the kinship matrix. Using simulated data and amino acid and exome-array data from the METabolic Syndrome In Men (METSIM) study, we show that Multi-SKAT can improve power over single-phenotype SKAT-O test and existing multiple-phenotype tests, while maintaining Type I error rate. PMID- 30298565 TI - Effects of galanin receptor 2 and receptor 3 knockout in mouse models of acute seizures. AB - There exists solid evidence that endogenous galanin and galanin agonists exert anticonvulsive actions mediated both by galanin 1 receptor (GAL1-R) and galanin 2 receptor (GAL2-R). We have now investigated whether depletion of the recently identified third galanin receptor, GAL3-R, and that of GAL2-R, alters the threshold to the systemically applied gamma-aminobutyric acid (GABA) antagonist pentylenetetrazole (PTZ) or to intrahippocampally administered kainic acid (KA). In neither model, GAL3-KO mice differed in their latency to the first seizure, mean seizure duration, total number of seizures, or time spent in seizures compared to wild-type controls. In addition, consistent with previous data, the response to PTZ was not altered in GAL2-KO mice. In contrast, intrahippocampal KA resulted in a significantly increased number of seizures and time spent in seizures in GAL2-KO mice, although the latency to the first seizure and the duration of individual seizures was not altered. These results are consistent with the previous data showing that GAL2-R knockdown does not affect the number of perforant path stimulations required for initiating status epilepticus but significantly increases the seizure severity during the ongoing status. In conclusion, our data support a specific role of GAL2-R but not of GAL3-R in mediating the anticonvulsive actions of endogenous galanin. PMID- 30298566 TI - The Impact of Medicaid Enrollment on Veterans Health Administration Enrollees' Behavioral Health Services Use. AB - OBJECTIVE: To examine Veterans Health Administration (VA) enrollees' use of VA services for treatment of behavioral health conditions (BHCs) after gaining Medicaid, and if VA reliance varies by complexity of BHCs. DATA SOURCES/STUDY SETTING: VA and Medicaid Analytic eXtract utilization data from 31 states, 2006 2010. STUDY DESIGN: A retrospective, longitudinal study of Veterans enrolled in VA care in the year before and year after enrollment in Medicaid among 7,249 nonelderly Veterans with serious mental illness (SMI), substance use disorder (SUD), posttraumatic stress disorder (PTSD), depression, or other BHCs. DATA COLLECTION/EXTRACTION METHODS: Utilization and VA reliance (proportion of care received at VA) for BH outpatient and inpatient services in unadjusted and adjusted analyses. PRINCIPAL FINDINGS: In adjusted analyses, we found that overall Veterans did not significantly change their use of VA outpatient BH services after Medicaid enrollment. In beta-binomial models predicting VA BH outpatient reliance, veterans with SMI (IRR = 1.38, p < .05), PTSD (IRR = 1.62, p < .01), and depression (IRR = 1.36, p < .05) had higher reliance than veterans with other BHCs after Medicaid enrollment. CONCLUSIONS: While veterans did not change the amount of VA outpatient BH services they used after enrolling in Medicaid, the proportion of care they received through VA or Medicaid varied by BHC. PMID- 30298567 TI - Parallel evolution of gene classes, but not genes: Evidence from Hawai'ian honeycreeper populations exposed to avian malaria. AB - Adaptation in nature is ubiquitous, yet characterizing its genomic basis is difficult because population demographics cause correlations with nonadaptive loci. Introduction events provide opportunities to observe adaptation over known spatial and temporal scales, facilitating the identification of genes involved in adaptation. The pathogen causing avian malaria, Plasmodium relictum, was introduced to Hawai'i in the 1930s and elicited extinctions and precipitous population declines in native honeycreepers. After a sharp initial population decline, the Hawai'i 'amakihi (Chlorodrepanis virens) has evolved tolerance to the parasite at low elevations where P. relictum exists, and can sustain infection without major fitness consequences. High-elevation, unexposed populations of 'amakihi display little to no tolerance. To explore the genomic basis of adaptation to P. relictum in low-elevation 'amakihi, we genotyped 125 'amakihi from the island of Hawai'i via hybridization capture to 40,000 oligonucleotide baits containing SNPs and used the reference 'amakihi genome to identify genes potentially under selection from malaria. We tested for outlier loci between low- and high-elevation population pairs and identified loci with signatures of selection within low-elevation populations. In some cases, genes commonly involved in the immune response (e.g., major histocompatibility complex) were associated with malaria presence in the population. We also detected several novel candidate loci that may be implicated in surviving malaria infection (e.g., beta-defensin, glycoproteins and interleukin-related genes). Our results suggest that rapid adaptation to pathogens may occur through changes in different immune genes, but in the same classes of genes, across populations. PMID- 30298568 TI - Predictors of nonalcoholic steatohepatitis and significant fibrosis in non-obese nonalcoholic fatty liver disease. AB - AIMS: We compared (a) demographic and clinical characteristics and (b) determinants of nonalcoholic steatohepatitis and significant fibrosis in non obese and obese nonalcoholic fatty liver disease. METHODS: A cross-sectional study of 664 Asian subjects (mean age 53.1 years; men 50.3%) with biopsy-proven nonalcoholic fatty liver disease and controls was conducted. Subjects were divided by their body mass index into obese (body mass index >=25 kg/m2 ) and non obese (body mass index <25 kg/m2 ). RESULTS: Observations in subjects with non obese nonalcoholic fatty liver disease were in between non-obese controls and subjects with obese nonalcoholic fatty liver disease for body mass index, sagittal abdominal diameter, aminotransferase levels, insulin resistance and abdominal visceral adipose tissue area. There was no significant difference in histology between non-obese and obese subjects with nonalcoholic fatty liver disease except for lower grade of hepatic steatosis in nonobese nonalcoholic fatty liver disease and higher severity of hepatic fibrosis in nonobese nonalcoholic steatohepatitis. Predictors of nonalcoholic steatohepatitis in nonobese subjects included females (odds ratio 2.49), higher alanine aminotransferase (odds ratio 1.03), lower high-density lipoprotein cholesterol (odds ratio 0.96), higher prevalence of diabetes (odds ratio 3.65) and higher visceral adipose tissue area (odds ratio 1.63 per standard deviation increase of visceral adipose tissue area) while age (odds ratio 1.04), higher aspartate aminotransferase (odds ratio 1.02), diabetes (odds ratio 2.76) and higher visceral adipose tissue area (odds ratio 1.57 per standard deviation increase) were associated with significant fibrosis in the non-obese. Sagittal abdominal diameter was independently associated with nonalcoholic steatohepatitis or significant fibrosis among subjects with non-obese nonalcoholic fatty liver disease. CONCLUSION: While there were a few phenotypic differences from obese subjects, non-obese subjects with nonalcoholic fatty liver disease displayed a similar severity of histological liver damage. Potential factor(s) beyond obesity may play a role as non-obese nonalcoholic fatty liver disease advances to more severe disease. PMID- 30298569 TI - Facilitation from an intraspecific perspective - stress tolerance determines facilitative effect and response in plants. AB - Plant-plant interactions are reciprocal and include effects on and response to neighbours. Distinct traits confer competitive effect and response ability, but how specific traits determine effect and response in facilitative interactions has not been studied experimentally. We utilized the model species Arabidopsis thaliana to test for trait dependence of facilitative interactions. Salt sensitive (sos) mutants or salt-tolerant wild-types were exposed to an experimental salinity gradient with and without intraspecific neighbours and the intensity of plant-plant interactions was measured for three performance variables. We tested whether salt tolerance can predict facilitative effect and response and whether a tradeoff exists between competitive ability and tolerance to stress. Interactions shifted very clearly from negative to positive with increasing stress. Salt-sensitive genotypes were less negatively affected by competition but more dependent on facilitation than were wild-types, indicating a tradeoff between competitive ability and stress tolerance. Surprisingly, sensitive genotypes imposed stronger facilitative effects, despite being much smaller under stress, probably because they retrieved more salt from the soil. Stress tolerance defined facilitative effect and response via distinct mechanisms. We advocate more controlled experiments with model species to advance our understanding of the trait dependence of biotic interactions and their consequences for community organization.

AB - Polysaccharides present in plant biomass, such as pectin, are the main carbon source for filamentous fungi. Aspergillus niger naturally secretes pectinases to degrade pectin and utilize the released monomers, mainly D-galacturonic acid. The transcriptional activator GaaR, the repressor of D-galacturonic acid utilization GaaX, and the physiological inducer 2-keto-3-deoxy-L-galactonate play important roles in the transcriptional regulation of D-galacturonic acid-responsive genes, which include the genes encoding pectinases. In this study, we described the mutations found in gaaX and gaaR that enabled constitutive (i.e., inducer independent) expression of pectinases by A. niger. Using promoter-reporter strains (PpgaX-amdS) and polygalacturonic acid plate assays, we showed that W361R mutation in GaaR results in constitutive production of pectinases. Analysis of subcellular localization of C-terminally eGFP-tagged GaaR/GaaRW 361R revealed important differences in nuclear accumulation of N- versus C-terminally eGFP tagged GaaR.

AB - Several legal interventions under the police power and parens patriae functions of the state depend partially on judgments that an individual is dangerous. Psychological research regarding risk assessment can provide relevant evidence regarding the appropriate application of these interventions. Developing, interpreting, and presenting relevant research regarding risk assessment in a manner that enhances the ability of courts to make accurate determinations of dangerousness requires clarification of the risk presented by this individual and explanation of how this person generates this risk. Testimony regarding such research can enhance the ability of the courts to make accurate judgments regarding the relationship between the risk presented and the justification for the specific intervention at issue. This article examines the justificatory functions of judgments of dangerousness for various police power and parens patriae interventions in order to clarify the manner in which psychological research and testimony can contribute to the ability of the courts to accurately assess the risk presented by an individual in making a judgment of dangerousness for a specific form of legal intervention. PMID- 30298572 TI - Anti-inflammatory disease-modifying treatment and disability progression in primary progressive multiple sclerosis: a cohort study. AB - BACKGROUND AND PURPOSE: Treatment options in primary progressive multiple sclerosis (PPMS) are scarce and, with the exception of ocrelizumab, anti inflammatory agents have failed to show efficacy in ameliorating disability progression. The aim of this study was to investigate a potential effect of anti inflammatory disease-modifying treatment on disability outcomes in PPMS. METHODS: Using MSBase, a large, international, observational database, we identified patients with PPMS who were either never treated or treated with a disease modifying agent. Propensity score matching was used to select subpopulations with similar baseline characteristics. Expanded Disability Status Scale (EDSS) outcomes were compared with an intention-to-treat and an as-treated approach in paired, pairwise-censored analyses. RESULTS: Of the 1284 included patients, 533 were matched (treated, n = 195; untreated n = 338). Median on-study pairwise censored follow-up was 3.4 years (quartiles 1.2-5.5). No difference in the hazard of experiencing 3-month confirmed EDSS progression events was observed between the groups [hazard ratio (HR), 1.0; 95% confidence interval (CI), 0.6-1.7, P = 0.87]. We did not find significant differences in the hazards of confirmed EDSS improvement (HR, 1.0; 95% CI, 0.6-1.6, P = 0.91) or reaching a confirmed EDSS step >=7 (HR, 1.1; 95% CI, 0.7-1.6, P = 0.69). CONCLUSION: Our pooled analysis of disease-modifying agents suggests that these therapies have no substantial effect on short- to medium-term disability outcomes in PPMS. PMID- 30298574 TI - Transcatheter arterial embolisation in four dogs with hepatocellular carcinoma. AB - Four dogs with hepatocellular carcinoma were treated by transcatheter arterial embolisation. In all dogs, the tumour-supplying arteries were selectively embolised with gelatine sponge particles. Post-embolisation tumour volumes decreased relative to pre-embolisation volumes in all dogs. No adverse reactions were observed in three dogs after treatment but one dog showed pancreatitis. These results suggest that transcatheter arterial embolisation is a feasible treatment for dogs with hepatocellular carcinoma.

PMID- 30298576 TI - Extracellular Hsp70 modulates the inflammatory response of cigarette smoke extract in NCI-H292 cells. AB - NEW FINDINGS: What is the central question of this study? Does extracellular heat shock protein 70 (eHsp70) alter cigarette smoke extract (CSE)-induced inflammatory responses in NCI-H292 bronchial epithelial cells? What is the main finding and its importance? eHsp70 modulates inflammatory responses and TLR2, TLR4 and Hsp70 gene expression, and protects NCI-H292 cells against CSE-induced cytotoxicity. eHsp70 might be implicated in development of inflammatory diseases affected by cigarette smoke, such as COPD. ABSTRACT: One of the major risk factors for development of chronic obstructive pulmonary disease (COPD) is cigarette smoke. Extracellular Hsp70 (eHsp70) is increased in sera of COPD patients, and can act as damage-associated molecular pattern (DAMP). In this study, we explored inflammatory parameters (cytokine concentrations, Toll-like receptor (TLR) 2 and 4 and Hsp70 expression, mitogen-activated protein kinases (MAPKs) and nuclear factor kappaB (NF-kappaB) activation, and cytotoxicity) after exposure of bronchial-epithelial NCI-H292 cells to cigarette smoke extract (CSE) alone (2.5 and 15%) and in combinations with recombinant human (rh) Hsp70 (0.3, 1 and 3 MUg ml-1 ). We applied specific MAPKs, NF-kappaB and Hsp70 inhibitors to elucidate rhHsp70 inflammation-associated responses. CSE alone and combinations of 15% CSE with rhHsp70 stimulated IL-1alpha, IL-6 and IL-8 release. However, rhHsp70 applied with 2.5% CSE decreased secretion of cytokines indicating antagonistic effects. Individual and combined treatments with 2.5% CSE suppressed TLR2 expression. CSE at 15% induced TLR2 and TLR4 gene expression, whereas rhHsp70 abolished that effect. rhHsp70 and 15% CSE alone reduced, while their combination increased, intracellular Hsp70 mRNA level. CSE alone and in combination with rhHsp70 activated extracellular signal-regulated kinase and p38 MAPKs, while inhibition of MAPKs, NF-kappaB and Hsp70 attenuated IL-6 and IL-8 secretion. CSE at 15% reduced cell viability and induced apoptosis, as shown by MTS and caspases-3/7 assays. CSE at 2.5% alone stimulated lactate dehydrogenase release, but cellular membrane integrity remained intact in co-treatments with rhHsp70. rhHsp70 might modulate the inflammatory response of CSE and could also protect NCI-H292 cells against CSE cytotoxicity. Those effects are implemented via MAPK and NF-kappaB signalling pathways. PMID- 30298577 TI - Transesophageal Echocardiographic Measurements of the Superior Vena Cava for Predicting Fluid Responsiveness in Patients Undergoing Invasive Positive Pressure Ventilation. AB - OBJECTIVES: Preoperative fasting, water deprivation, and intraoperative fluid loss and redistribution result in hypovolemia in patients undergoing surgery. Some findings have indicated that the superior vena cava (SVC) diameter and variation, as determined by transesophageal echocardiography during surgery, do not reflect central venous pressure effectively. This study aimed to compare and correlate the SVC diameter and variation with the stroke volume variation for predicting fluid responsiveness in patients undergoing invasive positive pressure ventilation. METHODS: Thirty-six patients scheduled for elective gastrointestinal surgery under general anesthesia with invasive positive pressure ventilation were included in this study. After anesthesia induction, the stroke volume variation, SVC diameter, mean arterial pressure, central venous pressure, and pulse were recorded, and measurements after fluid challenge were recorded as well. The SVC variation was calculated before and after the fluid challenge. RESULTS: After the fluid challenge, the SVC diameter markedly increased, whereas the SVC variation and stroke volume variation significantly decreased (P < .05). The optimal cutoff value for the SVC variation was 21.1%, and the area under the curve (AUC) from a receiver operating characteristic curve analysis was 0.849. The optimal cutoff value for the minimal SVC diameter was 1.135 cm, and that AUC was 0.929. In addition, the optimal cutoff value for the maximal SVC diameter was 1.480 cm, and the AUC was 0.862. CONCLUSIONS: The minimal SVC diameter may be an effective indicator for predicting fluid responsiveness in patients undergoing invasive positive pressure ventilation.

AB - Leakage of colonised oropharyngeal secretions across the tracheal tube cuff may cause iatrogenic pulmonary infection. We studied a novel 'add-on' cuff, which can be inserted over an existing tracheal tube and advanced into the subglottic region. The physical properties of the novel silicone cuff (BronchoGuard, Ciel Medical, USA) were evaluated in comparison with the Hi-Lo(r) tracheal tube. In a bench study, we identified saline inflation volumes required to transmit pressures between 15 and 30 cmH2 O against artificial tracheas of 18, 20 and 22 mm internal diameter. We computed cuff compliance, and minimal inflation volume to achieve air sealing during mechanical ventilation. Finally, we compared the leakage flow rate of artificial saliva across the novel cuff. On average, the mean (SD) inflation volumes necessary to transmit tracheal pressures of 15, 20, 25 and 30 cmH2 O were 4.1 (2.2), 4.4 (2.3), 4.6 (2.4) and 4.8 (2.4) ml for the novel cuff and 7.7 (2.5), 8.0 (2.6), 8.4 (2.6) and 8.7 (2.7) ml for the Hi-Lo tube, respectively (p < 0.001). The minimal inflation volumes to achieve air sealing were 3.8 (0.9) and 10.5 (2.1) ml (p < 0.001), which resulted in transmitted tracheal pressures of 8.3 (9.8) and 27.6 (34.8) cmH2 O (p < 0.001). Compliance was 0.026 (0.004) and 0.616 (0.324) ml.cmH2 0-1 , respectively (p < 0.001). Although massive leak was found when the novel cuff transmitted pressures <= 20 cmH2 O against the trachea, leakage was avoided with pressures >= 25 cmH2 O, owing to optimal contact between the cuff and the tracheal wall. In contrast, the standard cuff consistently leaked irrespective of the pressure. We conclude that the novel cuff has advantageous properties that warrant clinical corroboration.

PMID- 30298589 TI - Periodontal ligament-associated protein-1 gets involved in experimental periodontitis. AB - BACKGROUND AND OBJECTIVE: Periodontal ligament-associated protein-1 (PLAP-1) is an important regulator of osteogenic differentiation of periodontal ligament cells and plays important role in the homeostasis of periodontal tissues. But the role of PLAP-1 in periodontitis is poorly understood. Expressions of PLAP-1 in experimental periodontitis are observed to elucidate whether PLAP-1 gets involved in the pathogenesis of periodontitis. MATERIAL AND METHODS: Wistar rats were randomly allocated to two groups (n = 6/group): Ligation group and Control group. PLAP-1 expression in experimental periodontitis was assessed by immunohistochemistry and collagen fibers in periodontal ligament were observed using picrosirius red staining. Expressions of PLAP-1 and CD68 in periodontitis were colocalized by double-labelled immunofluorescence. To further examine the relationship between PLAP-1 and osteoclastogenesis in experimental periodontitis, acute periodontal inflammatory infiltration and alveolar bone destruction were induced by administering ligated rats with 10 ng/mL tumor necrosis factor alpha (TNF-alpha; ligation + TNF-alpha group, n = 6). Alveolar bone loss was observed by micro-computed tomography (Micro-CT), and osteoclasts were identified by tartrate-resistant acid phosphatase staining (TRAP). Expressions of PLAP-1 in TNF alpha stimulated human periodontal ligament cells were also detected at 24 and 48 hours by western blotting. RESULTS: PLAP-1 expression levels in periodontal ligament cells and collagen fibers were lower in the ligation group,compared with the control group. Similarly, TNF-alpha decreased PLAP-1 expression in human periodontal ligament cells in vitro. Degradation or destruction of collagen fibers accompanied the reduced PLAP-1 expression in the periodontal ligament in the ligation group. Colocalization of PLAP-1 and CD68 revealed the positive relationship between PLAP-1 and CD68+ infiltrating cells in periodontitis. More PLAP-1-positive inflammatory cells were found in the ligation + TNF-alpha group, compared with the ligation + saline group. CONCLUSION: PLAP-1-positive inflammatory cells are involved in the pathogenesis of periodontitis. An increase in PLAP-1-positive inflammatory cell number contributes periodontal inflammation and alveolar bone loss. PMID- 30298590 TI - Characterization and comparison of neutrophil extracellular traps in gingival samples of periodontitis and gingivitis: A pilot study. AB - BACKGROUND AND OBJECTIVE: Neutrophil extracellular traps (NETs) are a recently discovered antimicrobial mechanism used by neutrophils that have been proposed as an intervention in the pathogenesis of periodontitis. The objective of our study was to characterize the expression of NETs in gingival tissues with periodontitis and controls and to compare the expression of these traps in gingival tissue samples of patients with gingivitis and periodontitis. MATERIAL AND METHODS: An observational cross-sectional study was conducted on patients with periodontitis, gingivitis, and controls that needed tooth extraction. Gingival tissue biopsies were gathered after clinical examination and tooth extraction. Electron microscopy and immunofluorescence were performed to characterize NETs, comparing periodontitis and control patients. Immunohistochemical analysis was performed to quantify neutrophil extracellular trap expression through extracellular citrullinated histone H3 and myeloperoxidase in biopsies from patients with gingivitis and periodontitis. RESULTS: Thirteen biopsies were gathered from 13 patients: five gingivitis, six periodontitis, and two controls. Electron microscopy and immunofluorescence imaging showed greater expression of neutrophils present in periodontal inflamed tissue compared with controls. Release of nuclear content to the extracellular space was observed, compatible with the formation of NETs. The expression of citrullinated histone H3 was higher in gingivitis samples than periodontitis samples (P = 0.0106). Myeloperoxidase expression was higher in periodontitis than gingivitis, but without achieving statistical significance. CONCLUSION: Neutrophil extracellular traps were found in tissue samples of periodontitis as extracellular components of chromatin, along with neutrophil enzymes, that were not present in healthy controls. The comparison of NETs expression in periodontitis and gingivitis showed higher expression in gingivitis, associating them to acute phases of the periodontal inflammatory process. PMID- 30298591 TI - Can Doppler echocardiography estimate raised pulmonary capillary wedge pressure provoked by passive leg lifting in suspected heart failure? AB - AIMS: Non-invasive estimation of left ventricular filling pressure (LVFP) during stress is important for explaining exertional symptoms in patients with heart failure (HF). The aim of this study was to evaluate ability of Doppler echocardiographic measures of elevated LVFP with passive leg lifting (PLL) in patients with suspected HF. METHODS: Twenty-nine patients with clinical signs of HF who underwent simultaneous Doppler echocardiography and right heart catheterization (RHC) at rest and during PLL were consecutively investigated. Seventeen patients had normal PCWP (<=15 mmHg) at rest and during PLL and 12 with normal PCWP at rest but >15 mmHg with PLL. Conventional echo and 2D strain were used to assess early diastolic blood flow velocity (E), LV strain rate during early diastole (LVSRe), left atrial SR during atrial contraction (LASRa) and myocardial tissue Doppler velocities to assess lateral e' and further calculate E/e' and E/LVSRe and their relationship with PCWP, at rest and during PLL. RESULTS: Resting LAVI (beta = 0.45, P = 0.009) and LASRa (beta = -0.51, P = 0.004) were independently related to PCWP during PLL. Also, LASRa (beta = -0.77, P<0.001), E/e' (beta = 0.40, P = 0.04) and E/LVSRe (beta = 0.47, P = 0.021) during PLL correlated with PCWP during PLL. Multiple regression analysis identified E/LVSRe (beta = 0.46, P = 0.001) and LASRa (beta = -0.58, P = 0.002) during PLL as being independently associated with PCWP during PLL. CONCLUSION: Left atrial volume and myocardial contraction (LASRa) at rest both predict unstable LV filling pressures measured as raised PCWP when provoked by PLL. Furthermore, LASRa at PLL seems to have the strongest association to PCWP during PLL. PMID- 30298592 TI - The comparison of an acellular matrix graft with an autologous venous graft in the surgical treatment of Peyronie's disease. AB - The aim of this study was to evaluate acellular porcine pericardium (APP) and compared the results with those obtained from venous grafts in the surgical management of Peyronie's disease (PD). An APP (Group 1) and an autologous saphenous vein graft (Group 2) were used in 27 and 26 patients, respectively for Peyronie's correction. The patients' age, body mass index (BMI), operation time, duration of follow-up, preoperative and postoperative IIEF-5 scores, plaque size and loss of sensation were evaluated in both groups. There were no differences between the two groups in terms of age, BMI, follow-up period, and preoperative and postoperative IIEF-5 scores. The postoperative IIEF-5 scores were higher than the preoperative IIEF-5 scores in both groups. The operation time was significantly longer in Group 2 than in Group 1. The duration of sensation loss was shorter in Group 1 compared to Group 2. Penile shortening was similar in both groups. PMID- 30298593 TI - Self-expandable sirolimus-eluting stents compared to second-generation drug eluting stents for the treatment of the left main: A propensity score analysis from the SPARTA and the FAILS-2 registries. AB - OBJECTIVES: To compare the effectiveness and safety of self-expandable, sirolimus eluting Stentys stents (SES) and second-generation drug-eluting stents (DES-II) for the treatment of the unprotected left main (ULM). BACKGROUND: SES may provide a valuable option to treat distal ULM, particularly when significant caliber gaps with side branches are observed. METHODS: Patients from the multicenter SPARTA (clinicaltrials.gov: NCT02784405) and FAILS2 registries were included. Propensity score with matching was performed to account for the lack of randomization. Primary end-point was the rate of major adverse cardiovascular events (MACE, a composite of all cause death, myocardial infarction, target lesion revascularization [TLR], unstable angina and definite stent thrombosis [ST]). Single components of MACE were the secondary end-points. RESULTS: Overall, 151 patients treated with SES and 1270 with DES-II were included; no differences in MACE rate at 250 days were observed (9.8% vs. 11.5%, P = 0.54). After propensity score with matching, 129 patients treated with SES and 258 with DES-II, of which about a third of female gender, were compared. After a follow-up of 250 days, MACE rate did not differ between the two groups (9.9% vs. 8.5%, P = 0.66), as well as the rate of ULM TLR (1.6% vs. 3.1%, P = 0.36) and definite ST (0.8% vs. 1.2%, P = 0.78). These results were consistent also when controlling for the treatment with provisional vs. 2-stents strategies for the ULM bifurcation. CONCLUSION: SES use for ULM treatment was associated with a similar MACE rate compared to DES-II at an intermediate-term follow-up. SES might represent a potential option in this setting. PMID- 30298594 TI - Metabolic covariance networks combining graph theory measuring aberrant topological patterns in mesial temporal lobe epilepsy. AB - OBJECTIVE: We aimed to study the networks' mechanism of metabolic covariance networks in mesial temporal lobe epilepsy (mTLE), through examining the brain value of fluorine-18-fluorodeoxyglucose positron emission tomography (18 F-FDG PET). METHODS: 18 F-FDG-PET images from 16 patients with mTLE were analyzed using local and global metabolic covariance network (MCN) approaches, including whole metabolic pattern analysis (WMPA), hippocampus-based (h-) MCN, whole brain (w-) MCN, and edge-based connectivity analysis (EBCA). RESULTS: WMPA showed a typical ipsilateral hypometabolism and contralateral hypermetabolism pattern to epileptic zones in mTLE. h-MCN revealed decreased hippocampus-based synchronization in contralateral regions. w-MCN exhibited a disrupted metabolic network with globally increased small-world properties and regionally decreased nodal metrics in the ipsilateral hemisphere. Hippocampus (h)-EBCA and whole brain EBCA (w-EBCA) both detected a reduced-connectivity dominated metabolic covariant network. Moreover, the reduced interhemisphere connectivity seemingly played a major role in the aberrant epileptic topological pattern. CONCLUSION: From a metabolic point of view, we demonstrated the damaging effects with reduced contralateral intranetwork metrics properties and the compensatory effects in contralateral intranetworks with increased network properties. However, the import role of significant reduced interhemisphere connection has rarely been reported in other mTLE studies. Taken together, 18 F-FDG-PET MCN analysis provides new evidence that the mTLE is a system neurological disorder with disrupted networks. PMID- 30298595 TI - Simultaneous perfusion and permeability assessments using multiband multi-echo EPI (M2-EPI) in brain tumors. AB - PURPOSE: To study a multiband multi-echo EPI (M2-EPI) sequence for dynamic susceptibility contrast (DSC) perfusion imaging with leakage correction and vascular permeability measurements, and to evaluate the benefits of increased temporal resolution provided by this acquisition strategy on the accuracy of perfusion and permeability estimations. METHODS: A novel M2-EPI sequence was developed, and a pharmacokinetic model accounting for contrast agent extravasation was used to produce perfusion maps and additional vascular permeability maps. The advantage of M2-EPI for DSC perfusion imaging was demonstrated in vivo in 5 patients with brain tumors, and numerical simulations were performed to evaluate the advantage of improved temporal resolution afforded by the technique. RESULTS: In contrast to underestimations of cerebral blood volume (CBV) in tumors using the single-echo acquisition strategy, M2-EPI provided more plausible estimates of CBV. A quantitative evaluation showed higher estimated values of CBV and mean transit time in tumor tissues using M2-EPI (CBV: 3.08 +/- 0.78 mL/100 g versus 1.56 +/- 1.38 mL/100 g [P = .006]; mean transit time: 4.94 +/- 1.17 seconds versus 1.83 +/- 2.06 seconds [P = 0.033]). Numerical simulations showed that higher temporal resolution provided by M2-EPI was associated with more accurate estimates of cerebral blood flow, CBV, and permeability parameters. CONCLUSION: The novel M2-EPI acquisition strategy for DSC imaging facilitates leakage-corrected perfusion measurements with additional permeability assessments and more accurate estimates of perfusion/permeability parameters, and may be used as a quantitative tool for the diagnosis, prognosis, and treatment monitoring of brain tumors. PMID- 30298596 TI - Decision-making in dentistry related to temporomandibular disorders: a 5-yr follow-up study. AB - Temporomandibular disorders (TMDs) are common, but many patients with such disorders go undetected and under-treated. Our aim was to evaluate the outcome of using a screening tool (5 yr after it was first implemented), on the clinical decision-making for patients with TMDs. Adults who attended for a dental check-up at the Public Dental Health Services in Vasterbotten, Sweden, answered three screening questions (3Q/TMD) on frequent jaw pain, pain on jaw function, and catching/locking of the jaw. The dental records of a random sample of 200 individuals with at least one positive response to 3Q/TMD (3Q screen-positive patients) and 200 individuals with all negative responses (3Q screen-negative patients) were reviewed for TMD-related treatment decisions. A clinical decision related to TMD was absent in 45.5% of 3Q screen-positive patients. Treatment of TMDs was associated with a positive response to the screening question on jaw pain (OR = 6.7, 95% CI: 3.2-14.0) and was more frequent among 3Q screen-positive patients (24%) than among 3Q screen-negative patients (2%; OR = 15.5, 95% CI: 5.5 43.9), just as a female examiner was associated with more frequent treatment of TMDs (OR = 3.1, 95% CI: 1.2-8.4). The results indicate under-treatment of TMD within general dental practice and that male clinicians are less likely to initiate TMD treatment. PMID- 30298597 TI - Analysis of Pseudomonas putida growth on non-trivial carbon sources using transcriptomics and genome-scale modelling. AB - Pseudomonas putida is characterized by a versatile metabolism and stress tolerance traits that allow the bacterium to cope with different environmental conditions. In this work, the mechanisms that allow P. putida KT2440 to grow in the presence of four sole carbon sources (glucose, citrate, ferulic acid, serine) were investigated by RNA sequencing (RNA-seq) and genome-scale metabolic modelling. Transcriptomic data identified uptake systems for the four carbon sources, and candidates were subjected to preliminary experimental characterization by mutant strain growth to test their involvement in substrate assimilation. The OpdH and BenF-like porins were involved in citrate and ferulic acid uptake respectively. The citrate transporter (encoded by PP_0147) and the TctABC system were important for supporting cell growth in citrate; PcaT and VanK were associated with ferulic acid uptake; and the ABC transporter AapJPQM was involved in serine transport. A genome-scale metabolic model of P. putida KT2440 was used to integrate and analyze the transcriptomic data, identifying and confirming the active catabolic pathways for each carbon source. This study reveals novel information about transporters that are essential for understanding bacterial adaptation to different environments. PMID- 30298598 TI - Fisher's influence on me. AB - This is the 100th year anniversary of Fisher's 1918 paper "The correlation between relatives on the supposition of Mendelian inheritance" (Transactions of the Royal Society of Edinburgh 1918, 52 pp 899-438). Fisher's work has had a strong influence on today's genetic epidemiology and this brief autobiographical note highlights a few of the ways his influence on me has affected the field. Although I once took a course of lectures from Fisher, it was mainly his writings that influenced my statistical thinking. Not only did the concept of maximum likelihood appeal to me, but also the concepts of interclass and intraclass correlations, discriminant analysis, and transforming semiquantitative scores to minimize interactions-all topics I first learned about from the 11th edition of his book on Statistical Methods for Research Workers. This, together with a few serendipitous events that shaped my career, had a large influence on me and hence also on the field of genetic epidemiology.

AB - MPV17 encodes a putative channel-forming protein of the inner mitochondrial membrane and is involved in mitochondrial deoxynucleotide homeostasis. MPV17 mutations were first reported in patients with Navajo neurohepatopathy, an autosomal recessive mitochondrial DNA depletion syndrome, characterized by early onset liver failure, failure to thrive as well as central and peripheral neurological involvement. Recently, two patients with juvenile-onset peripheral sensorimotor neuropathy associated with an MVP17 c.122G>A (p.Arg41Gln) variant have been reported. Here, we describe five additional patients from two unrelated families with sensorimotor axonal neuropathy without hepatocerebral affection caused by homozygous MPV17 variants. Patients of the first family carried the known c.122G>A variant and affected individuals of the second family had a novel c.376-9T>G near-splice variant, which was shown to result in an in-frame deletion of 11 amino acids. This report provides further evidence that MPV17 mutations should be considered in patients with pure, non-syndromic axonal neuropathy. PMID- 30298601 TI - Evolution of thermal tolerance in multifarious environments. AB - Species extinction rates are many times greater than the direst predictions made two decades ago by environmentalists, largely because of human impact. Major concerns are associated with the predicted higher recurrence and severity of extreme events, such as heat waves. Although tolerance to these extreme events is instrumental to species survival, little is known whether and how it evolves in natural populations, and to what extent it is affected by other environmental stressors. Here, we study physiological and molecular mechanisms of thermal tolerance over evolutionary times in multifarious environments. Using the practice of "resurrection ecology" on the keystone grazer Daphnia magna, we quantified genetic and plastic differences in physiological and molecular traits linked to thermal tolerance in historical and modern genotypes of the same population. This population experienced an increase in average temperature and occurrence of heat waves, in addition to dramatic changes in water chemistry, over five decades. On genotypes resurrected across the five decades, we measured plastic and genetic differences in CTmax , body size, Hb content and differential expression of four heat shock proteins after exposure to temperature as single stress and in combination with food levels and insecticide loads. We observed evolution of the critical thermal maximum and plastic response in body size, HSP expression and Hb content over time in a warming only scenario. Molecular and physiological responses to extreme temperature in multifarious environments were not predictable from the response to warming alone. Underestimating the effect of multiple stressors on thermal tolerance can lead to wrong estimates of species evolvability and persistence.

AB - Dinoflagellates of the genus Dinophysis are the most persistent producers of lipophilic shellfish toxins in Western Europe. Their mixotrophic nutrition requires a food chain of cryptophytes and plastid-bearing ciliates for sustained growth and photosynthesis. In this study, cultures of D. acuminata and D. acuta, their ciliate prey Mesodinium rubrum and the cryptophyte, Teleaulax amphioxeia, were subject to three experimental settings to study their physiological response to different combinations of light intensity and quality. Growth rates, pigment analyses (HPLC), photosynthetic parameters (PAM-fluorometry), and cellular toxin content (LC-MS) were determined. Specific differences in photosynthetic parameters were observed in Dinophysis exposed to different photon fluxes (10-650 MUmol photons . m-2 . s-1 ), light quality (white, blue and green), and shifts in light regime. Dinophysis acuta was more susceptible to photodamage under high light intensities (370-650 MUmol photons . m-2 . s-1 ) than D. acuminata but survived better with low light (10 MUmol photons . m-2 . s-1 ) and to a prolonged period (28 d) of darkness. Mesodinium rubrum and T. amphioxeia showed their maximal growth rate and yield under white and high light whereas Dinophysis seemed better adapted to grow under green and blue light. Toxin analyses in Dinophysis showed maximal toxin per cell under high light after prey depletion at the late exponential-plateau phase. Changes observed in photosynthetic light curves of D. acuminata cultures after shifting light conditions from low intensity-blue light to high intensity-white light seemed compatible with photoacclimation in this species. Results obtained here are discussed in relation to different spatiotemporal distributions observed in field populations of D. acuminata and D. acuta in northwestern Iberia.

AB - BACKGROUND: Mental health concerns are important for adolescent's general wellbeing and they can be associated with their ability to function effectively in various aspects of their daily life. AIM: The purpose of this study was to identify emotional and behavioral disorders (EBD) among Jordanian adolescents and their association with academic outcomes. METHODS: A descriptive correlational design was used. A total of 810 adolescents participated in the study and completed the demographic survey and the Strengths and Difficulties Questionnaire (SDQ). The grade point average (GPA) was used as an indicator of the academic achievement. The GPA was correlated with the SDQ scores to identify the relationship between the EBD and academic achievement. RESULTS: About 11.7% of the participants had psychological and behavioral problems. The most commonly reported problems were emotional symptoms (14.2%), conduct problems (12.5%), and hyperactivity (7.5%). There was a significant difference in psychological and behavioral problems according to the participants' gender. There was a significant negative relationship between the SDQ scores and the GPA. CONCLUSION: There is a need to identify adolescents at risk of emotional and behavioral difficulties and refer them to appropriate care and support, which in turn would improve their academic achievement. PMID- 30298604 TI - Managing bullying in Swedish workplace settings: A concealed and only partially acknowledged problem. AB - AIM: The purpose of this article was to explore workplace routines and strategies for preventing and managing bullying in the context of health and elderly care. BACKGROUND: Bullying is a serious problem in workplaces with consequences for the individual, the organisation and the quality of care. METHOD: Open-ended interviews were conducted with 12 participants, including managers and specialists within one hospital and three municipalities. The interviews were analysed with qualitative content analysis. RESULTS: Bullying was often concealed, due to avoidance, unclear definition and lack of direct strategies against bullying. No preventative work focusing on bullying existed. Psychosocial issues were not prioritized at workplace meetings. The supervisor had the formal responsibility to identify, manage and solve the bullying problem. The most common decision to solve the problem was to split the group. CONCLUSIONS: The findings showed that bullying was a concealed problem and was first acknowledged when the problem was acute. IMPLICATIONS FOR NURSING MANAGEMENT: Crucial strategies to prevent and combat bullying consist of acknowledgement of the problem, transformational leadership, prioritization of psycho-social issues, support of a humanistic value system and work through bullying problems to achieve long-term changes. PMID- 30298605 TI - Humic substances reduce ruminal methane production and increase the efficiency of microbial protein synthesis in vitro. AB - BACKGROUND: In ruminants, enteric CH4 represents a major energy loss for the host and is a potent greenhouse gas that contributes to climate change. Previous studies have shown that humic substances (HS) may have beneficial effects on livestock nutrition. The present study investigated the effects of HS on in vitro CH4 production and rumen fermentation. RESULTS: Total gas production was linearly increased with increasing HS after 12 h of incubation, although it was unaffected after 24 and 48 h. Increasing HS linearly decreased CH4 at all time points. Increasing HS linearly decreased NH3 -N concentration and the molar proportion of acetate at 12 h, whereas the efficiency of microbial protein (MP) production and total dry matter digestibility (TDMD) linearly increased, with starch digestion (SD) responding quadratically. After 48 h, HS linearly increased MP and TDMD, with neutral detergent fibre digestibility responding quadratically. CONCLUSION: Inclusion of HS effectively reduced CH4 production and increased substrate disappearance and the efficiency of microbial protein synthesis in vitro. However, its effect on in vivo CH4 production, rumen fermentation and ruminant production requires further investigation. (c) 2018 Society of Chemical Industry.

University students may have irrational beliefs that could play a significant role in causing emotional disturbance. Nevertheless, a suitable instrument for measuring irrational beliefs in college students in Chinese society has been lacking. The aim of this study was to construct a culturally relevant scale for measuring irrational beliefs among university students in the Hong Kong Chinese context. The construction of the Chinese Irrational Beliefs and Rational Attitude Scale (CIBRAS) for university students was based on (1) literature review and expert panel review for evaluation on content validity, (2) a pilot test of 200 local Hong Kong university students to determine the scale's psychometric properties and probe the exploratory factor analysis, and (3) confirmatory factor analysis to test for construct validity of the CIBRAS (conducted with a further 655 local Hong Kong university students). The results showed that the five-factor 19-item CIBRAS has good psychometric properties, including good internal consistency (Cronbach's alphas ranging from .64 to .80), content validity (content validity index = .96 for relevance, .94 for clarity, and .94 for representativeness), construct validity (explaining 60.1% of the total variance), and adequate fit indices (normed chi-square = 2.8, comparative fit index = .94, normal fit index = .93, non-normed fit index = .93, incremental fit index = .94, root-mean-square error of approximation = .077, and standardized root-mean residual = .074). The limitations and implications of the study were discussed. PMID- 30298607 TI - Necrotizing enterocolitis attenuates developmental heart rate variability increases in newborn rats. AB - BACKGROUND: We have shown previously that a decreased high-frequency spectrum of heart rate variability (HF-HRV), indicative of reduced vagal tone, shows promise in predicting neonates likely to develop necrotizing enterocolitis (NEC) before its clinical onset. We hypothesized that NEC induction in rat pups decreases HF HRV power; subdiaphragmatic vagotomy worsens the severity of the NEC phenotype, increases levels of pro-inflammatory cytokines, and alters the myenteric phenotype. METHODS: Newborn Sprague-Dawley rats, representative of preterm human neonates, were subjected to 7-8 days of brief periods of cold stress and hypoxia to induce NEC with or without unilateral subdiaphragmatic vagotomy. HRV was measured at postnatal days one and five, pups were sacrificed at day 8/9, and gastrointestinal tissues and blood were collected for immunohistochemical, corticosterone, and cytokine analysis. KEY RESULTS: Compared to control, NEC induced rats showed the following: (a) typical histological signs of grade 2 NEC, which were more severe in rats that underwent vagotomy; (b) reduced developmental increases in time (RMSSD) and frequency (HF) HRV spectra when combined with the stress of laparotomy/vagotomy; (c) increases in nitric oxide synthase immunoreactivity in the myenteric plexus of jejunum and ileum; furthermore, compared to mild NEC and controls, vagotomized NEC rats had increased plasma values of pro-inflammatory cytokines IL-1beta and IL-6. CONCLUSIONS AND INFERENCES: Our data suggest that in rodents, similar to neonatal observations, NEC induction attenuated developmental HF-HRV increases, furthermore, subdiaphragmatic vagotomy worsened the histological severity, increased pro inflammatory cytokines, and altered the nitrergic myenteric phenotype, suggesting a role of the vagus in the development of NEC pathology. PMID- 30298608 TI - Benefit of early versus deferred antiretroviral therapy on progression of liver fibrosis among people with HIV in the START randomized trial. AB - BACKGROUND: The role of antiretroviral therapy (ART) in reducing or contributing to liver fibrosis in persons with HIV is unclear. We evaluated participants in the Strategic Timing of AntiRetroviral Treatment trial (START) for liver fibrosis using the AST to platelet ratio index (APRI) and Fibrosis-4 Index (FIB-4), and assessed for a benefit of early versus delayed antiretroviral therapy (ART) on liver fibrosis progression. DESIGN AND INTERVENTION: ART-naive persons with high CD4 counts (>500 cells/MUL) from 222 clinical sites in 35 countries were randomized to receive ART either at study enrolment (immediate treatment arm) or when their CD4 count fell below 350 cells/MUL (deferred treatment arm). The following outcomes were evaluated: fibrosis (APRI>0.5 or FIB-4>1.45), significant fibrosis (APRI>1.5 or FIB-4>3.25), hepatic flare, and resolution of elevated APRI and FIB-4 scores. RESULTS: Of the 4684 enrolled into the START study, 104 did not have APRI or FIB-4 results and were excluded. Among 4580 participants (2273 immediate treatment; 2307 deferred treatment), the median age was 36 years, 26.9% were female, and 30.4% were black. Three percent had an alcoholism or substance abuse history, 6.4% had hepatitis, and 1.1% had significant fibrosis at baseline. The median CD4 count was 651 and 5.3% had HIV RNA<=200. Immediate arm participants were at lower risk of developing increased fibrosis scores than deferred arm participants (hazard ratio [HR]=0.66; 95% confidence interval [CI]=0.57-0.78; p<0.001), and more likely to have resolution of elevated baseline scores (HR 1.6; 95% CI 1.3-1.9; p<0.001). CONCLUSIONS: Significant liver fibrosis was rare among ART-naive HIV-positive persons with high CD4 counts. Our findings suggest a benefit of early ART in preventing the development of liver fibrosis. This article is protected by copyright. All rights reserved. PMID- 30298609 TI - Vertical Step-Growth Polymerization Driven by Electrochemical Stimuli from an Electrode. AB - We present herein the vertical step-growth polymerization of a monomer A-B through individual A-A or B-B coupling driven by electrochemical switching of positive and negative bias on a self-assembled A or B electrode. The monomer RuII (bda)AB (bda=2,2'-bipyridine-6,6'-dicarboxylate), in which A and B are pyridine moieties with pendant carbazolyl and vinyl groups, could be dimerized at oxidative (ca. 1.0 V vs. Ag/Ag+ ) or reductive potential (ca. -1.8 V) to give a self-assembled RuII (bda)PA or RuII (bda)PB monolayer (P=pyridine with a pendant phosphonic acid) on ITO glass. This polymerization enabled the sequence- and topology-controlled synthesis of surface-confined molecular wires with single molecule precision on an electrode. The electrocatalytic performance of the vertically orientated molecular wires for water oxidation increased with increasing molecular length and exceeded that of both the self-assembled monolayer and a randomly electropolymerized film, which have previously been studied as typical models. PMID- 30298610 TI - Developing a critical trans gerontology. AB - Within existing academic literature, ageing within trans populations has primarily been addressed from the perspective of offering advice to service providers and clinicians, with relatively limited application of critical sociological perspectives. This article seeks to integrate the critical perspectives on gerontology with transfeminism, identifying areas of commonality regarding accounts of an integrated lifecourse, scepticism of biomedicalization, and an emphasis on local context. The article suggests that this integration provides a fruitful basis for developing future research into the study of trans ageing, and also provides theoretical development across many debates around age, gender and the lifecourse. PMID- 30298611 TI - Cluster capture-recapture to account for identification uncertainty on aerial surveys of animal populations. AB - Capture-recapture methods for estimating wildlife population sizes almost always require their users to identify every detected animal. Many modern-day wildlife surveys detect animals without physical capture-visual detection by cameras is one such example. However, for every pair of detections, the surveyor faces a decision that is often fraught with uncertainty: are they linked to the same individual? An inability to resolve every such decision to a high degree of certainty prevents the use of standard capture-recapture methods, impeding the estimation of animal density. Here we develop an estimator for aerial surveys, on which two planes or unmanned vehicles (drones) fly a transect over the survey region, detecting individuals via high-definition cameras. Identities remain unknown, so one cannot discern if two detections match to the same animal; however, detections in close proximity are more likely to match. By modeling detection locations as a clustered point process, we extend recently developed methodology and propose a precise and computationally efficient estimator of animal density that does not require individual identification. We illustrate the method with an aerial survey of porpoise, on which cameras detect individuals at the surface of the sea, and we need to take account of the fact that they are not always at the surface.

AB - BACKGROUND AND PURPOSE: Post-stroke dysphagia occurs in up to three quarters of patients with acute stroke and is associated with a higher risk of respiratory infections and poor outcome. Systematic screening of dysphagia in the acute stroke unit is essential to identify patients at risk of aspiration and to provide dietary recommendations. Our study aimed to assess the impact of the systematic application of the Gugging Swallowing Screen (GUSS) in patients with acute ischaemic stroke. METHODS: This was a retrospective study of consecutive patients with acute ischaemic stroke admitted to an acute stroke unit in two time periods: pre-GUSS (February 2014-July 2015), when the 10-mL water-swallowing test was systematically administered, and GUSS (August 2015-October 2016), when the GUSS test was systematically administered. Groups were compared with regard to baseline and stroke characteristics, and the occurrence of stroke-associated pneumonia (SAP), in-hospital death and 3-month outcome. RESULTS: Of the 344 patients who were included in the study (median age 71 years), 51.7% were male with a median National Institutes of Health Stroke Scale score of 11. A total of 204 patients were included during the pre-GUSS period and 140 during the GUSS period. Patients in the GUSS period more frequently had diabetes and partial anterior circulation syndromes, and were more frequently treated with thrombectomy. There was no difference in the occurrence of SAP between the two groups (pre-GUSS, 12.5%; GUSS, 15.1%; P = 0.490) and no differences were found concerning in-hospital mortality (P = 0.996), 3-month functional independence (P = 0.647) or 3-month mortality (P = 0.598). CONCLUSIONS: The systematic administration of GUSS in a population of patients with acute ischaemic stroke did not reduce the occurrence of SAP, mortality or 3-month functional dependence when compared with the systematic administration of the 10-mL water-swallowing test. PMID- 30298613 TI - Life-sentenced juveniles: Public perceptions of risk and need for incarceration. AB - Pursuant to recent United States Supreme Court decisions in Miller v. Alabama (2012) and Montgomery v. Louisiana (2016), individuals convicted of crimes committed when they were younger than 18 and for which they received mandatory life sentences are entitled to new sentencing hearings. This study examined public perceptions of such individuals (life-sentenced juveniles, or LSJs). Study participants were 663 adults (52.3% male) ages 22-71 years (M = 36.00, SD = 11.46) recruited using Amazon Mechanical Turk (MTurk). Each participant received one of a possible four vignettes about a man who was incarcerated for a crime that occurred when he was 17 years old and subsequently sentenced to mandatory life in prison following conviction. Two variables (risk of harming others if released to the community, and circumstances of the crime) were manipulated in a 2 * 2 between-subjects design. Each participant read one vignette and then answered questions relating to appropriateness for release from prison. Results indicate that risk, but not circumstances of the crime, strongly influenced participants' views regarding resentencing. When the individual in the vignette was labeled as high risk, participants described him as less appropriate for release, more deserving of punishment, needing more rehabilitation, and more appropriate for specific and general deterrence. The circumstances of the crime had no effect on participants' responses. This may be important for various reasons, as applicable law does not explicitly identify risk as a consideration in juvenile resentencing. The nonetheless noteworthy empirical influence of risk on perceptions regarding LSJs is discussed in their implications for research, policy, and practice. PMID- 30298614 TI - Views of Appropriate Use Criteria for catheterization and percutaneous coronary revascularization by practicing interventional cardiologists: Results of a survey of American College of Cardiology Interventional Section members. AB - OBJECTIVES: The American College of Cardiology (ACC) Interventional Section Council leadership sought to examine the views of interventional cardiologists regarding the practical implementation and the value of the Appropriate Use Criteria (AUC) in their clinical practice. BACKGROUND: The ACC AUC for revascularization were originally intended to assess trends in revascularization patterns by hospitals and physicians to ensure that both under- and over utilization were minimized. As a quality assurance tool, the AUC were designed to allow physicians to obtain insight into their practice patterns and improve their practice. Recent trends toward tying payment to performance have raised concerns that these criteria will be incorrectly applied to individual patient reimbursement, which is not what they were designed to do. Consequently, the AUC have become controversial, not for their value in quality assessment, but for the manner in which agencies have used the AUC as a tool to potentially deny payment for certain patients. METHODS: Utilizing an online survey, members of the ACC Interventional Section were queried regarding the use of AUC, how they use them, and how they feel utilization impacts the care of patients. RESULTS: We found substantial variability in how the AUC were utilized and concern regarding the value of AUC. Among our findings was that respondents were split (51% vs 49%) regarding the value of AUC to patients and/or their laboratory. CONCLUSIONS: In this article, we discuss the implications of these findings and consider options on how AUC might be made a better-accepted and more impactful tool for clinicians and patients.

AB - BACKGROUND: Due to the current dominance of a few grape varieties in the wine market, the aim of this work was to study the detailed phenolic and volatile composition, chromatic characteristics, and sensorial properties of red wines elaborated with new Vitis vinifera grapes (Moribel and Tinto Fragoso) identified using the High Perfomance Liquid Chromatography-Diode Array Detector-Electrospray Ionization-Tandem Mass Spectrometry (HPLC-DAD-ESI-MS/MS), Gas Chromatography- Mass Spectrometry (GC-MS), CIELab color space, and Napping (r) techniques. RESULTS: Tinto Fragoso wine showed higher phenolic content than Moribel, with more anthocyanins, flavonols, and stilbenes. These wines also contained anthocyanin diglucosides not reported for Vitis vinifera wines. The odor activity values of free volatile compounds were calculated to indicate their influence on wine aroma, the fruity aromas of Moribel standing out particularly. The wines studied were positively evaluated by the tasters. Moribel's sensory profile was characterized by red fruit aromas and Tinto Fragoso showed more aromatic intensity and persistence in the mouth. CONCLUSION: The results obtained from the first characterization of red wines made from novel Vitis vinifera grapes suggest that Moribel and Tinto Fragoso could be appropriate raw materials for the elaboration of quality young red wines. Tinto Fragoso provided wines with sensorial properties different from those of Tempranillo, and could be an alternative to the well known red wines on the market.

AB - BACKGROUND: Photosynthetic pigments perform critical physiological functions in tea plants. Their content is an essential indicator of photosynthetic efficiency and nutritional status. The present study aimed to predict chlorophyll a (Chl a), chlorophyll b (Chl b), total chlorophyll (total Chl), and carotenoid (Car) content in tea leaves under different levels of nitrogen treatment using hyperspectral imaging (HSI) in combination with variable selection algorithms. RESULTS: A total of 150 samples were collected and scanned using the HSI system. The mean spectrum in the region of interest (ROI) was extracted, and the pigment content was measured by traditional chemical methods. Five and seven optimal wavelengths (OWs) were selected using the regression coefficients (RCs) of partial least squares regression (PLSR) and the second-derivative (2-Der), respectively. The optimal 2-Der-PLSR models for Chl a, Chl b, total Chl, and Car performed remarkably well based on seven OWs with correlation coefficients of prediction (RP ) of 0.9337, 0.9322, 0.9333 and 0.9036, root mean square errors in prediction (RMSEP) of 0.1100, 0.0511, 0.1620, and 0.0300 mg g-1 , respectively. CONCLUSION: The results of this study revealed that HSI combined with variable selection method can be employed as a rapid and accurate method for predicting the content of pigments in tea plants.

Wats) is one of the most common and troublesome weeds in the USA. Palmer amaranth resistance to ALS inhibitors is widespread in the USA as in Arkansas. The cross-resistance patterns and mechanism of resistance are not known. Experiments were conducted to (1) determine cross-resistance to ALS-inhibitors and (2) identify target-site mutations in 20 Palmer amaranth localities from 13 counties in Arkansas. RESULTS: All Palmer amaranth localities tested had plants cross-resistant to imazethapyr, flumetsulam, primisulfuron, pyrithiobac, and trifloxysulfuron. The dose of trifloxysulfuron that caused 50% control was 21- to 56-fold greater for resistant accessions than susceptible ones. All but three resistant plants analyzed had one or two relative copies of ALS; one plant had seven relative copies. All resistant plants tested (18 localities) carried the Trp574 Leu mutation, which is known to confer broad resistance to ALS inhibitors, supporting the cross-resistance pattern observed. Besides Trp574 Leu mutation, 30% of localities had individuals with one additional resistance-conferring mutation including either Ala122 Thr, Pro197 Ala, or Ser653 Asn. CONCLUSION: Trp574 Leu mutation in ALS is the primary mechanism of resistance to ALS inhibitors in Palmer amaranth from Arkansas, USA. In some localities, multiple mutations have accumulated in one plant. All localities tested contained plants with resistance to five families of ALS inhibitors. Localities with extreme high resistance to ALS inhibitors, and those outside of the subset we studied, may harbor non-target site resistance mechanisms. ALS inhibitors are generally no longer effective on Palmer amaranth in these localities from the US mid-south. This article is protected by copyright. All rights reserved. PMID- 30298619 TI - Enhanced Production of High-Value Cyclopropane Fatty Acid in Yeast Engineered for Increased Lipid Synthesis and Accumulation. AB - The unique strained ring structure in cyclopropane fatty acids (CFA) conveys oxidative stability and lubricity to lipids. These attributes are highly valuable for industrial applications such as cosmetics and specialist lubrication but there is currently no commercial source of the lipid. Here, built on recently engineered strains of Saccharomyces cerevisiae, the authors have developed an efficient strategy for CFA production. Expression of the Escherichia coli cyclopropane fatty acid synthetase (Ec.CFAS) in the engineered yeast resulted in formation of cis-9,10-methylene-hexadecanoic and octadecanoic acids in both the phospholipid (PL) and triacylglycerol (TAG) fractions. CFA concentration in TAG of engineered yeast is 12 mg CFA g-1 DCW (fourfold above the strain expressing CFAS only). The yield of CFA increases from 13.2 to 68.3 mg L-1 , the highest reported in yeast, using a two-stage bioprocess strategy that separated cell growth from the lipid modification stage. Strategies for further improvement of this valuable lipid are proposed. PMID- 30298620 TI - Protective effects of omega-3 fatty acids against Alzheimer's disease in rat brain endothelial cells. AB - OBJECTIVES: Omega-3 fatty acids are well-known unsaturated fatty acids that are essential for growth and development in animals. They primarily participate in the development of intelligence, the nervous system, and vision, and the metabolism of neurotransmitters. Omega-3 fatty acids have been widely studied in the treatment of Alzheimer's disease (AD). Omega-3 fatty acids are known to have neuroprotective effects due to their antioxidant capacity. Rotenone has been shown to induce neurotoxicity in vitro. METHODS: We investigated the protective effects of omega-3 fatty acids against AD in rat brain microvascular endothelial cells (RBMVECs) in vitro. Lipid peroxidation, reactive oxygen species (ROS), glutathione peroxidase (Gpx), reduced glutathione (GSH), superoxide dismutase (SOD), and catalase levels were evaluated in RBMVECs. Flow cytometry was performed to assess apoptosis. RESULTS: Lipid peroxidation and ROS were reduced in RBMVECs following incubation with omega-3 fatty acids. Catalase, Gpx, and SOD were increased in RBMVECs following incubation with omega-3 fatty acids. Flow cytometry showed that incubation with omega-3 fatty acids reduced the amount of apoptotic RBMVECs. CONCLUSION: Our results suggest that omega-3 fatty acids show potential as a therapeutic agent against AD. PMID- 30298621 TI - Switching the manufacturer of antiepileptic drugs is associated with higher risk of seizures: A nationwide study of prescription data in Germany. AB - OBJECTIVE: Despite bioequivalence, the exchangeability of antiepileptic drugs in clinical settings is disputed. Therefore, we investigated the risk for recurrent seizures after switching the manufacturer of the same drug in a large German cohort. METHODS: Anonymous patient data from practice neurologists throughout Germany between 2011 and 2016 were collected using the IMS Disease Analyzer database (QuintilesIMS, Frankfurt, Germany). People with epilepsy were included if at least 2 prescriptions within 360 days and 1 within 180 days prior to the index date were available. The cohort was separated into a seizure group and seizure-free controls. Both groups were matched 1:1 according to age, gender, insurance status, and treating physician. The risk for breakthrough seizures after a manufacturer switch of the same antiepileptic drug was analyzed using multivariate regression models. RESULTS: A total of 3,530 people with epilepsy were included (each group, n = 1,765; age = 53.7 +/- 19.8 years). Patients with seizures had switched the drug manufacturer more often than controls (26.8% vs 14.2%; odds ratio [OR] = 1.35, 95% confidence interval [CI] = 1.08-1.69, p = 0.009), both from branded to generic (5.5% vs 2.4%; OR = 1.85, 95% CI = 1.30 2.64, p < 0.001) and between generic drugs (14.7% vs 7.1%; OR = 1.45, 95% CI = 1.13-1.87, p = 0.004). INTERPRETATION: In previously seizure-free patients, switching the manufacturer of antiepileptic medications was associated with a higher risk for seizure recurrence. Our retrospective approach does not allow us to determine whether other changes in medical care at the same time could contribute to the recurrence. However, it would be prudent to avoid switching the manufacturer of anticonvulsants in seizure-free patients. Ann Neurol 2018. PMID- 30298622 TI - High prevalence of congenital deafness on Reunion Island is due to a founder variant of LHFPL5. AB - Reunion Island is a French oversea department in the Indian Ocean with 1.6/1000, an estimated prevalence of deafness that is almost double as compared to the mainland France. Twelve children having isolated bilateral prelingual profound deafness along with motor delay attributed to vestibular areflexia were enrolled. Their mean walking age was 19 months. Electroretinography and temporal bone CT scans were normal in all cases. A novel homozygous frameshift lipoma HMGIC fusion partner-like 5 (LHFPL5) variant c.185delT p.(Phe62Serfs*23) was identified using whole-exome sequencing. It was found in seven families. Four patients from two different families from both Reunion Island and mainland France, were compound heterozygous: c.185delT p.(Phe62Serfs*23) and c.472C > T p.(Arg158Trp). The phenotype observed in our patients completely mimics the hurry-scurry (hscy) murine Tmhs knock-out model. The recurrent occurrence of same LHFPL5 variant in Reunion Island is attributed to common ancestor couple born in 1693.

AB - The 2 D assembly of polymers to form free-standing and large crystalline films is quite appealing but very challenging. Although there have been some works using interface templates, reports of in situ assembly in solution are still rare. Herein, a simple strategy is developed for the creation of a free-standing and centimeter-sized 2 D crystalline polymer film through crystallization of an amphiphilic brush polydiacetylene (PDA) in solution. The film exhibits good shape memory, a low dielectric constant, and good carrier mobility. This strategy may be applied extensively to produce a variety of other macroscopic 2 D crystalline polymer films for applications in electronics, catalysis, and so on.

AB - The present study used a new, digitized version of the impression replica technique, namely the dual-scan technique, to evaluate the adaptation of single crown fixed dental prostheses (FDPs). Scans of the bare master model and of the master model with a silicone layer representing the cement layer were superimposed and analyzed using designated software. Single crowns produced using the lost-wax metal casting technique were included. The cement space of the band width, 0.5-1.0 mm from the preparation margin (marginal fit), was smallest for crowns made from laser-sintered cobalt-chromium. The internal fit in both mesial distal and buccal-palatal directions was statistically significantly better for crowns made using the conventional lost-wax metal casting technique than for crowns produced using computer-aided design/computer-aided manufacturing (CAD/CAM). Fixed dental prostheses produced by milled cobalt-chromium had the loosest internal fit. The results agree with those of our previous study of the same test specimens, in which the triple-scan method was used, and imply that the dual-scan method is well suited for adaptation studies.

AB - Aortic valve surgery is the definitive treatment for aortic stenosis (AS). No specific recommendation is available on how exercise training should be conducted and evaluated after aortic valve replacement (AVR). This study aimed to examine the effect of aerobic exercise training on exercise capacity following AVR. In addition to our primary outcome variable, peak oxygen uptake (peakVO2 ), the effect on submaximal cardiopulmonary variables including oxygen uptake kinetics (tau), oxygen uptake efficiency slope (OUES) and ventilatory efficiency (VE/VCO2 slope) was evaluated. Following AVR due to AS, 12 patients were randomized to either a group receiving 12 weeks of supervised aerobic exercise training (EX) or a control group (CON). Exercise capacity was assessed by a maximal cardiopulmonary exercise test (CPET). There was a significant increase in peak load (+28%, P = 0.031) and in peakVO2 (+23%, P = 0.031) in EX, corresponding to an increase in achieved percentage of predicted peakVO2 from 88 to 104% (P = 0.031). For submaximal variables, there were only non-statistically significant trends in improvement between CPETs in EX. In CON, there were no significant differences in any maximal or submaximal variable between CPETs. We conclude that 12 weeks of supervised aerobic exercise training induces significant adaptations in cardiopulmonary function following AVR, especially in regard to maximal variables including peakVO2 . In addition, we provide novel data on the effect on several submaximal variables following exercise training in this group of patients. PMID- 30298626 TI - Dietary nutrient levels alter the metabolism of arginine family amino acids in the conceptus of Huanjiang mini-pigs. AB - BACKGROUND: The arginine family amino acids (AFAAs) exert important roles in the metabolism, growth and development of the conceptus. However, to date, few studies have investigated the effects of maternal nutrient levels on the concentrations and metabolism of AFAAs in the conceptus. RESULTS: Compared to low nutrient diets, high nutrient diets increased (P < 0.05) the concentrations of citrulline and proline (Pro) in plasma; the concentrations of arginine, glutamine, Pro and ornithine (Orn) in the amniotic fluid; and the concentrations of all detected AFAAs in the allantoic fluid, which were most pronounced on day 45 of pregnancy. High nutrient diets upregulated (P < 0.05) mRNA expression of arginase I (Arg I), Pro oxidase and spermidine synthetase (SRM) in the fetal placenta, as well as Arg II, SRM and spermine synthetase (SMS) expression in the fetal liver (most pronounced on day 45 of pregnancy). The same effect was observed for mRNA expression of NO synthase and Orn aminotransferase (OAT), mainly on day 110 of pregnancy, and for mRNA expression of Arg I, Arg II, OAT, Orn decarboxylase and SMS throughout pregnancy. High nutrient diets upregulated (P < 0.05) mRNA expression of Y+ L-type amino acid transporter (LAT) and cationic amino acid transporter 1 (CAT1) in the fetal jejunum throughout pregnancy. Dietary treatments did not affect (P > 0.05) mRNA expression of Y+ LAT1, sodium coupled neutral amino acid transporter 2 (SNAT2) and CAT1 in the fetal placenta, skeletal muscle and colon. CONCLUSION: High nutrient diets increased the concentration and transport of AFAAs in the mothers and conceptus, which likely improves growth and development of the conceptus.

PMID- 30298627 TI - Abnormal Fasting Glucose Increases Risk of Unrecognized Myocardial Infarctions in an Elderly Cohort. AB - OBJECTIVES: To investigate glucose levels as a risk factor for unrecognized myocardial infarctions (UMIs). DESIGN: Cohort SETTING: Cardiovascular Health Study. PARTICIPANTS: Individuals aged 65 and older with fasting glucose measurements (N=4,355; normal fasting glucose (NFG), n = 2,041; impaired fasting glucose (IFG), n = 1,706; DM: n = 608; 40% male, 84% white, mean age 72.4 +/- 5.6). MEASUREMENTS: The relationship between glucose levels and UMI was examined. Participants with prior coronary heart disease (CHD) or UMI on initial electrocardiography were excluded. Using Minnesota codes, UMI was identified according to the presence of pathological Q-waves or minor Q-waves with ST-T abnormalities. Crude and adjusted hazard ratios (HRs) were calculated. Analyses were adjusted for age, sex, body mass index (BMI), hypertension, antihypertensive and lipid-lowering medication use, total cholesterol, high-density lipoprotein cholesterol, and smoking status. RESULTS: Over a mean follow-up of 6 years, there were 459 incident UMIs (NFG, n=202; IFG, n=183; DM, n=74). Participants with IFG were slightly more likely than those with NFG to experience a UMI (hazard ratio (HR)=1.11, 95% confidence interval (CI)=0.91-1.36, p = .30), and those with DM were more likely than those with NFG to experience a UMI (HR=1.65, 95% CI=1.25 2.13, p < .001). After adjustment HR for UMI in IFG those with IFG were no more likely than those with NFG to experience a UMI (HR=1.01, 95% CI=0.82-1.24, p = .93), whereas those with DM were more likely than those with NFG to experience a UMI (HR=1.37, 95% CI=1.02-1.81, p = .03). The 2-hour oral glucose tolerance test was not statistically significantly associated with UMI. CONCLUSION: Fasting glucose status, particularly in the diabetic range, forecasted UMI during 6 years of follow-up in elderly adults. Further studies are needed to clarify the level of glucose at which risk is greater. PMID- 30298629 TI - Implementing a salutogenic treatment model in a clinical setting of emergency child and adolescent psychiatry in Sweden. AB - PROBLEM: Emergency care in child and adolescent psychiatry often lacks a coherent treatment model. This study reports on the development and implementation of a salutogenic treatment model at the Child & Adolescent Psychiatric Emergency Unit in Malmo, Sweden. METHODS: The development and implementation involved all staff categories and was guided by a recognized authority on salutogenesis. Generalized resistance resources (GRR) were identified that could be implemented at the unit to improve patients' sense of coherence. FINDINGS: Eight GRR were developed and implemented at the unit. During the 6-month period following the implementation, patients (n = 41) and parents reported satisfaction with the treatment, while mental health improved between admission and discharge, and both treatment length and readmission rates were reduced. CONCLUSION: A salutogenic treatment model involving GRR seems to be a promising approach in child and adolescent psychiatric emergency treatment. PMID- 30298630 TI - Virtual screening of naphthoquinone analogs for potent inhibitors against the cancer-signaling PI3K/AKT/mTOR pathway. AB - The PI3K/AKT/mTOR pathway is one of the most commonly disrupted signaling pathways that plays a role in the development and pathogenicity of multiple cancers. Therefore, the critical proteins of this pathway have been targeted for anticancer therapy. The scientific community has increasingly been realizing the anti-cancer therapeutic potential of naphthoquinone analogs. These compounds constitute a major class of diverse sets of plant metabolites, which include various natural products and synthetic compounds with proven anticancer activity. The current study involved structural computational biology approaches to explore compounds from a diverse pool of naphthoquinone analogs that can inhibit key cancer-signaling proteins phosphoinositide 3-kinase (PI3K), protein kinase B, PKB (AKT), and mammalian target of rapamycin (mTOR). The novel compound identified commonly among the top 10 dock score lists of PI3K, AKT, and mTOR was selected for further study and proposed as a potential inhibitor of the 3 cancer-signaling proteins and an anticancer agent. Further, to check the docking accuracy and potential of the compound, post docking analyses, namely, binding comparison with the native ligand, the role of the interacting residue role in binding, predicted binding energy and dissociation constant calculations, etc., were performed. All these measures showed good-quality binding, and thus provide weight to our prediction of the novel compound as a pan PI3K/AKT/mTOR inhibitor and an anticancer agent. Finally, to compare the binding and similarity in the active sites of the 3 protein kinases, a ligand-based active site alignment was performed and analyzed. Thus, the study proposed a novel naphthoquinone analog as a potential anticancer drug, and provided comparative structural insight into its binding to the 3 protein kinases.

AB - OBJECTIVES: The objective of this paper was to explore the effects of Radix isatidis polysaccharide (RIP) extracted from Radix isatis on alleviating insulin resistance. METHODS: The insulin resistance models of 3T3-L1 preadipocytes and type 2 diabetic rats were established to evaluate the insulin resistance activity of RIP. KEY FINDINGS: Radix isatidis polysaccharide within the concentration range of 25-100 MUg/ml could reduce cell supernatant glucose and TNF-alpha levels (P < 0.01) and increase the expression of PI-3K P85, Glut4, IRS-1 and Akt protein in symptoms of IR 3T3-L1 preadipocytes. In the meantime, RIP contributed to relieve the weight loss of diabetic rats whose liver weight and liver index were decreased due to the effects of RIP. Experiments in rats also showed that RIP had capacity in reduced serum TC, TG, LDL-C, FFA, FBG, FINS, MDA, ALT, AST activities and increased serum HDL-C, SOD, ISI (P < 0.05 or 0.01). In addition, the oral glucose tolerance in rats was improved (P < 0.05) and liver damage was restored due to RIP. CONCLUSIONS: Radix isatidis polysaccharide significantly alleviates insulin resistance in 3T3-L1 preadipocytes and type 2 diabetic rats. These beneficial effects of RIP may associate with their roles in improving the glucose metabolism, lipid metabolism and oxidative stress. PMID- 30298634 TI - Terraced and Smooth Gradient Polymer Brushes via a Polymer Single-Crystal Assisted Grafting-To Method. AB - Gradient polymer brushes provide a spatial gradient change in molecular characteristics of the brush, and such a change can be utilized to study structure-property relationships in a combinatorial fashion. In this study, a bottom-up method was used to synthesize gradient polymer brushes with a predesigned and precisely controlled grafting density gradient and brush pattern. A polymer single-crystal assisted grafting-to (PSCAGT) method was employed where end-functionalized polymers were grown into two-dimensional polymer single crystals. The latter were chemically coupled to a solid substrate to form well defined polymer brushes. To tune the grafting density, end-dissimilar polymers were used to co-crystallize into one single crystal. Programmed single-crystal growth was introduced to synthesize brushes with two different gradient architectures, that is, terraced and smooth gradient with pyramid patterns. This work demonstrates that the PSCAGT method offers a unique means to tune polymer brush nanostructure. PMID- 30298635 TI - Detecting Counterfeit Brandies. AB - A hypothesis-free sensor array (optoelectronic tongue) composed of an anionic, a cationic and two neutral poly(para-aryleneethynylene)s (PAE) at pH 3, 7 and 13 discriminate more than 30 spirits (including brandy, Branntwein, Cognac, Spirituose, and Weinbrand). Counterfeits (made by mixing of low-quality spirits and caramel colour) and different batches of identical brands of brandies are discriminated. The sensor array works without sample preparation or great instrumental cost, and is superior to conventional methods with respect to sample need (10-20 MUL), time and effort. The discrimination stems from differential fluorescence quenching of the PAE-array by the complex mixture of the beverages' colourants, from the oak barrels or added caramel colour. The collected quenching data were analysed by linear discriminant analysis (LDA) and principal component analysis (PCA) to achieve successful discrimination. PMID- 30298636 TI - A folic acid-enriched diet attenuates prostate involution in response to androgen deprivation. AB - BACKGROUND: Serum folate concentrations in the United States have risen since dietary folic acid fortification was first mandated in 1998. Although maternal folic acid offers protection against neural tube defects in conceptuses, its impact on other organ systems and life stages have not been fully examined. Here, we used a mouse model to investigate the impact of a Folic acid (FA) enriched diet on prostate homeostasis and response to androgen deprivation. METHODS: Male mice were fed a control diet (4 mg FA/kg feed) or a folic acid supplemented diet (24 mg FA/kg feed) beginning at conception and continuing through early adulthood, when mice were castrated. RESULTS: We made the surprising observation that dietary FA supplementation confers partial resistance to castration-mediated prostate involution. At 3, 10, and 14 days post-castration, FA enriched diet fed mice had larger prostates as assessed by wet weight, taller prostatic luminal epithelial cells, and more abundant RNAs encoding prostate secretory proteins than castrated control diet fed mice. Diet did not significantly affect prostate weights of intact mice or serum testosterone concentrations of castrated mice. RNA-Seq analysis revealed that the FA enriched diet was associated with a unique prostate gene expression signature, affecting several signaling and metabolic pathways. CONCLUSIONS: Continuous exposure to a FA enriched diet slows prostate involution in response to androgen deprivation. Prostates from FA diet mice have increased secretory gene expression and increased luminal cell heights. The influence of dietary FA supplementation on the prostate response to androgen deprivation raises a future need to consider how dietary folic acid supplementation affects efficacy of androgen-reducing therapies for treating prostate disease. PMID- 30298637 TI - Oxidative stress-induced alterations in seminal plasma antioxidants: Is there any association with keap1 gene methylation in human spermatozoa? AB - Kelch-like ECH-associated protein 1 (keap1)-nuclear factor-erythroid 2-related factor 2 (Nrf2) pathway is one of the master regulators of cellular defence against oxidative stress. Epigenetic alterations like hypermethylation of keap1 gene impair keap1-Nrf2 system in several oxidative stress-associated diseases. The objective of this study was to evaluate the epigenetic status of keap1 in sperm DNA of normozoospermic subjects, having different levels of reactive oxygen species (ROS) in seminal plasma. Semen samples were obtained from 151 apparently healthy male partners of couples who attended the Avicenna infertility clinic. Samples were categorised into four groups according to their ROS levels: group A (n = 39, ROS < 20 RLU/s per 106 spermatozoa), group B (n = 38, 20 <= ROS < 40 RLU/s per 106 spermatozoa), group C (n = 31, 40 <= ROS < 60 RLU/s per 106 spermatozoa) and group D; (n = 43, ROS >= 60 RLU/s per 106 spermatozoa). Keap1 methylation status was assessed using methylation-specific PCR along with seminal total antioxidant capacity. The results showed no significant alterations in keap1 methylation in any groups, whereas the total antioxidant capacity enhanced with increasing levels of ROS exposure. These results indicate that keap1 was not methylated during ROS elevation and oxidative stress, suggesting that the cells have adopted other mechanisms to elevate antioxidant level. PMID- 30298638 TI - Patient-Reported outcome measures and their utility in the management of patients with advanced chronic kidney disease. AB - Symptom and quality of life (QOL) measures in patients with advanced chronic kidney disease (CKD) are recognised indicators of patient-centred care and represent important research, quality and clinical measures. This study examined relationships between symptom burden, QOL and functional status and associations of symptoms and mortality risk. A multisite longitudinal cohort analysis was undertaken in CKD stage 4/5 (no dialysis, ND) and dialysis patients. Patients completed symptom and QOL measures (Palliative Care Outcome Symptom Score (POS-S renal) [1], World Health Organisation QOL, WHOQOL-BREF) [2] and Karnofsky Performance scale [3]. Clinical and demographic data were recorded. Participants recruited were 112 dialysis and 40 ND patients. High symptom burden was present and correlated with lower QOL, QOL subdomains and reduced performance status. Comparing groups found a small significant difference in physical QOL suggesting dialysis treatment burden. Further analysis was restricted comparing 102 dialysis and 31 CKD stage 4 (CKD4) patients. Dialysis patients had above target adequacies, but poorer appetite, nausea, vomiting and difficulty sleeping compared with CKD4 patients. Overall, the most prevalent symptoms were also the most severe, specifically pain, dyspnea, weakness, difficulty sleeping. Cox Proportional Hazards regression showed severe pain, nausea, vomiting, poor mobility, itch and skin changes were significantly associated with shorter survival in dialysis patients. Severe symptom score was associated with mortality risk (HR 1.1, 95%CI(1.03,1.17) compared with no increased risk with comorbidity score or age. Patients with advanced CKD had significant symptom burden correlated with poorer QOL. Symptoms may also be useful in considering clinical outcomes, specifically mortality.

PMID- 30298639 TI - Rapid ultrasound-assisted dispersive solid-phase extraction of nonsteroidal anti inflammatory drugs in urine using oleic acid functionalized magnetic graphene oxide. AB - We describe an ultrasound-assisted magnetic dispersive solid-phase extraction based on oleic acid functionalized magnetic graphene oxide followed by high performance liquid chromatography with ultraviolet detection. The method was applied for the simultaneous determination of ibuprofen, diclofenac, naproxen, and mefenamic acid in urine. The application of sonication led to the good dispersion of the sorbent, and consequently, significant shortened the extraction time. The sorbent was successfully characterized by different techniques. The influence of the adsorption parameters was optimized using a rotational central composite design. In order to improve desorption efficiency, parameters such as type and volume of the eluent and sonication time were investigated and optimized through a one variable at a time method. Under the optimum conditions, limits of detection and precision were between 3.0-25 ng/mL (n = 5) and 3.2-7.1%, respectively. The preconcentration factors were found to be 74 for naproxen, 76 for diclofenac, 80 for ibuprofen, and 66 for mefenamic acid corresponding to the absolute recovery within the range of 82.5-100%. Finally, the proposed method was successfully applied for simultaneous determination of target analytes in human urine samples. The relative recovery was within the range of 91.4-113.3%, indicating the good reliability and accuracy of the method. PMID- 30298641 TI - A longitudinal study of hymenoptera stings in preschool children. AB - BACKGROUND: Insect venom is the second most common cause of anaphylaxis outside of medical encounters. Stings cause over 20% of all anaphylactic deaths and 7% of anaphylaxis in children. To date, there have been no longitudinal studies of insect sting events or allergy in preschool children. METHODS: A prospective longitudinal nested observational study in the BASELINE Birth Cohort Study (n = 2137). Sting-related questions were asked at 6 and 12 months and 2 and 5 years. Skin prick testing (SPT) was performed at 2 and 5 years. SpIgE testing was performed on selected cases at 2 years. RESULTS: Seventy-seven children (6.8%) were stung by the age of 2. Of these, 25 (32.5%) reported adverse reactions (four systemic). Eleven (0.9%) had positive SPT at 2 years (eight bee, two wasp, one both). Four stung children had positive SPT. Two (one stung, one never stung) had positive spIgE to a venom component at 2 years. A total of 268 children (21.9%) were stung by 5 years, 144 (52.1%) reporting local reactions and none systemic. Four children (0.4%) had positive SPT at 5 years: one bee and three wasp. Of the 11 SPT-positive children at 2 years, none were still positive at 5 years. CONCLUSION: This is the first longitudinal study of the natural history of hymenoptera stings and allergy in preschool children. Hymenoptera venom allergy is less common in this cohort than in adults. Systemic reactions were not medically documented in this population, in keeping with previous literature. This study confirms the poor correlation of IgE sensitization to venom with sting allergy and does not support the common parental request to screen children for sting allergy. PMID- 30298642 TI - Dropping to escape: a review of an under-appreciated antipredator defence. AB - Dropping is a common antipredator defence that enables rapid escape from a perceived threat. However, despite its immediate effectiveness in predator-prey encounters (and against other dangers such as a parasitoid or an aggressive conspecific), it remains an under-appreciated defence strategy in the scientific literature. Dropping has been recorded in a wide range of taxa, from primates to lizards, but has been studied most commonly in insects. Insects have been found to utilise dropping in response to both biotic and abiotic stimuli, sometimes dependent on mechanical or chemical cues. Whatever the trigger for dropping, the decision to drop by prey will present a range of inter-related costs and benefits to the individual and so there will be subtle complexities in the trade-offs surrounding this defensive behaviour. In predatory encounters, dropping by prey will also impose varying costs and benefits on the predator - or predators - involved in the system. There may be important trade-offs involved in the decision made by predators regarding whether to pursue prey or not, but the predator perspective on dropping has been less explored at present. Beyond its function as an escape tactic, dropping has also been suggested to be an important precursor to flight in insects and further study could greatly improve understanding of its evolutionary importance. Dropping in insects could also prove of significant practical importance if an improved understanding can be applied to integrated pest-management strategies. Currently the non-consumptive effects of predators on their prey are under-appreciated in biological control and it may be that the dropping behaviour of many pest species could be exploited via management practices to improve crop protection. Overall, this review aims to provide a comprehensive synthesis of the current literature on dropping and to raise awareness of this fascinating and widespread behaviour. It also seeks to offer some novel hypotheses and highlight key avenues for future research. PMID- 30298640 TI - Weaker semantic language lateralization associated with better semantic language performance in healthy right-handed children. AB - INTRODUCTION: The relationship between language abilities and language lateralization in the developing brain is important for our understanding of the neural architecture of language development. METHODS: We investigated 35 right handed children and adolescents aged 7-16 years with a functional magnetic resonance imaging language paradigm and a comprehensive language and verbal memory examination. RESULTS: We found that less lateralized language was significantly correlated with better language performance across areas of the brain and across different language tasks. Less lateralized language in the overall brain was associated with better in-scanner task accuracy on a semantic language decision task and out-of-scanner vocabulary and verbal fluency. Specifically, less lateralized frontal lobe language dominance was associated with better in-scanner task accuracy and out-of-scanner verbal fluency. Furthermore, less lateralized parietal language was associated with better out-of scanner verbal memory across learning, short- and long-delay trials. In contrast, we did not find any relationship between temporal lobe language laterality and verbal performance. CONCLUSIONS: This study suggests that semantic language performance is better with some involvement of the nondominant hemisphere. PMID- 30298643 TI - A Photovoice study on nurses' perceptions and experience of resiliency. AB - AIM: To explore the meaning of resilience to nurses and their perceived resilience enhancing factors. BACKGROUND: With challenges faced at work, nurses' professional quality of life is adversely affected with nurses experiencing compassion fatigue, depression, burnout and even signs of post-traumatic stress disorder. Degree of resilience can determine job satisfaction and nursing attrition. METHODS: The study adopted a descriptive qualitative design using Photovoice. Eight nurses from an academic medical centre in Singapore participated in focus group interviews and data were analysed with inductive content analysis approach. RESULTS: Four themes were generated: (a) resilience is performing nursing duties despite adversities; (b) resilience is a dynamic process that develops over time; (c) religion and faith help build resilience; and (d) support of others is important in overcoming work-related stress. CONCLUSIONS: Knowledge on resilience is vital to understand influencing factors of personal resilience and relationship to stress and burnout. Building nurses' resilience is significant to improve and sustain healthy and effective functioning of nurses. IMPLICATIONS FOR NURSING MANAGEMENT: With sufficient external resources and psychosocial support from hospital administrators, early resilience-based approach may provide the buffer and protective factor in facing workplace stress, to improve overall job satisfaction and improve nurses' retention. PMID- 30298644 TI - A tripartite toxin-antitoxin module induced by quorum sensing is associated with the persistence phenotype in Streptococcus mutans. AB - The oral pathogen Streptococcus mutans communicates using a canonical Gram positive quorum sensing system, CSP-ComDE. The CSP pheromone already known to be involved in the development of genetic competence positively influences the formation of persisters, dormant variants of regular cells that are highly tolerant to antimicrobial therapy. It is now believed that the persistence phenotype is the end result of a stochastic switch in the expression of toxin antitoxin (TA) modules. TAs consist of a pair of genes that encode two components, a stable toxin and its cognate labile antitoxin. Transcription analyses revealed that three core genes encoding a putative TA system, called SmuATR, were members of the S. mutans CSP regulon. We hypothesized that S. mutans is using its CSP-ComDE system as a deterministic mechanism for persister formation through the activation of smuATR locus. We showed here that the SmuATR system constitutes a novel tripartite type II TA system in which the smuA and smuT genes encode an antitoxin and a toxin, respectively, while SmuR is a transcriptional repressor involved in the autoregulation of the operon. Ectopic expression of SmuA - SmuT is associated with the CSP-inducible persistence phenotype. In contrast, overexpression of SmuT alone is bactericidal and causes membrane permeabilization. To our knowledge, SmuATR is the first functional chromosomal tripartite TA system shown to be induced by the bacterial quorum sensing system and involved in persister formation. PMID- 30298645 TI - Perspectives in renal replacement therapy: Haemodialysis. AB - Haemodialysis (HD) was the first procedure that had demonstrated the ability to partially replace renal function, and became the most widely utilized treatment for patients with end-stage renal disease (ESRD). In a great majority of countries around the world, conventional in-centre HD had become the predominant renal replacement therapy, being touted as able to achieve better solute clearance and more successful in attaining euvolemia than patients on peritoneal dialysis. This is despite the antecedent hemodynamic risks, more rapid loss of residual renal function, greater infectious perils, excessive erythropoietin requirements and higher infrastructure costs. In addition, quality of life had been suggested to be worse among patients on HD, though this had been challenged repeatedly. Consequently, the concept of integrated ESRD care over the last few decades had placed HD, as a complementary rather than a competitive treatment modality to the entire armamentarium of renal replacement therapies. Incorporating HD as part of integrated care into health-care policies and national resource planning will become an essential strategy in improving access and outcome to care among the ESRD population. The improvement in technologies and innovation in prescription had brought forth enhanced dialyzer membrane and machine upgrades, and expanded modalities including more frequent HD and haemodiafiltration. While boasting of controversial improvement in outcomes, many of these therapies remain expensive and insurmountable for widespread utility in many countries. In addition, the results of these new technologies had been conflicting across studies, with some even suggesting that they could be detrimental. Therefore, judicial consideration has to be undertaken to appropriate their use in clinical practice. PMID- 30298646 TI - Glomerular mesangial cell and podocyte injuries in diabetic nephropathy. AB - Diabetic nephropathy is one of the leading causes of end-stage renal disease and creates heavy healthcare burdens globally. Dysfunction of mesangial cells and podocytes contributes to diabetic nephropathy. Dysregulation of signaling involved in renal development and regeneration may cause diabetic kidney damages. Growing evidences suggest the importance of dysregulated dickkopf-1 (DKK1)/Wnt/ beta-catenin signaling pathways in the pathogenesis of diabetic glomerular injuries. The inhibition of Wnt signaling in injured mesangial cells is likely attributed to the high glucose-induced Ras/Rac1 dependent superoxide formation. When DKK1, the cellular inhibitor of Wnt signaling, binds to the Kremen-2 receptor, depositions of extracellular matrix increase in the mesangium of diabetic kidneys. Additionally, reactivation of Notch-1 signaling has been implicated in podocytopathy during diabetic proteinuria development. Knocking down Notch-1 alleviates vascular endothelial growth factor (VEGF) expression, nephrin repression and proteinuria in diabetic kidneys. It is also found that epigenetic modulations by histone deacetylase 4 (HDAC4) and miR-29a could lead to diabetic nephropathy. High glucose increases the expression of HDAC4, which causes deacetylation with subsequent ubiquitination of nephrin. Overexpression of miR-29a in diabetic transgenic mice would decrease the expression of HDAC4 and stabilize nephrin. Surprisingly, reprogramming or reactivation of signaling involved in renal development or regeneration often brings about diabetic glomerular sclerosis in mesangial cells and podocytes. Better knowledge about modifications of embryonic stem cell signaling will have a chance to implement strategically focused pharmacological research programs aiming to the development of new drugs for diabetic kidney injuries. PMID- 30298647 TI - Maternal obesity and offspring risk of chronic kidney disease. AB - It is increasingly recognized that maternal obesity is implicated in developmental programming, contributing to the future risk of chronic disease development in offspring. The exact mechanisms of the role of maternal obesity in the development of chronic kidney disease in offspring remain unclear and animal models used are not without limitation. Human studies are limited by the effects of postnatal environmental conditions, which may have a direct impact on disease phenotype; and animal models are limited by use of species that differ significantly. This review will examine the most recent evidence from animal models on the impact of maternal factors during pregnancy/lactation on the future risk of chronic kidney disease development in offspring, emphasising the role of maternal obesity in exacerbating the deleterious effects of diet-induced obesity and/or diabetes on renal health. PMID- 30298648 TI - Biomarkers for acute cardiorenal syndrome. AB - Cardiorenal syndromes are disorders of the heart and kidneys whereby dysfunction in one organ may lead to dysfunction in the other organ. Cardiorenal syndrome type I (CRS I) is defined as acute kidney injury caused by acute cardiac dysfunction such as acute decompensated heart failure and acute coronary syndrome. Traditional markers like serum creatinine may delay the diagnosis of acute kidney injury and provide limited information regarding the underlying pathophysiology in the setting of CRS I. Herein, we briefly review some emerging biomarkers, including brain natriuretic peptide, soluble ST2, angiopoietin, soluble thrombomodulin, neutrophil gelatinase-associated lipocalin, kidney injury molecule-1, cystatin C, interleukin-18 and calprotectin. These biomarkers may help early detecting, differential diagnosis, assessing disease severity and prognosis in patients with CRS I, therefore improve patient management and outcomes. PMID- 30298649 TI - Association between albumin and C-reactive protein and ankle-brachial index in haemodialysis. AB - AIM: Peripheral artery occlusive disease (PAOD) is associated with increased rates of cardiovascular mortality, morbidity and hospitalization in patients undergoing dialysis. An ankle-brachial index (ABI) less than 0.9 has been used to diagnose PAOD. The aim of this study was to evaluate associations among inflammation, malnutrition and their interactions on the risk of PAOD. METHODS: Two hundred and twenty-two haemodialysis patients (mean age 61.0 +/- 11.7 years, 56.8% men) were enrolled and stratified into four groups according to median values of albumin (3.87 g/dL) and logarithm of C-reactive protein (CRP) (0.48 mg/L). Associations between the study groups and an ABI less than 0.9 were assessed using multiple logistic regression analysis. Receiver operating characteristic curves were constructed to predict an ABI less than 0.9. RESULTS: A lower level of albumin and higher level of CRP were significantly associated with an ABI less than 0.9 in multivariate analysis (odds ratio, 5.688; 95% confidence interval, 1.369-23.626; P = 0.017) after adjusting for demographic, clinical, biochemical and medication data. The interaction between albumin and CRP in relation to an ABI less than 0.9 was significant in multivariate analysis (odds ratio, 1.797; 95% confidence interval, 1.258-2.568; P = 0.001). The areas under the curve for albumin, CRP and albumin + CRP for the prediction of ABI less than 0.9 were 0.311, 0.654 and 0.733, respectively. CONCLUSION: Patients undergoing haemodialysis with a lower albumin level and higher CRP level have an increased risk of PAOD. A combination of malnutrition and inflammation may be associated with PAOD in haemodialysis patients. PMID- 30298650 TI - Epigenetic targeting for acute kidney injury. AB - In recent years, epigenetics has emerged as important mechanisms for the regulation of pathogenesis in many diseases, including acute kidney injury (AKI). Numerous studies have demonstrated that AKI is associated with the changes in epigenetics, including histone modifications, DNA methylation and the expression of various non-coding RNAs. Through utilizing histone deacetylase (HDAC) inhibitors, studies have demonstrated that increase of histone acetylation either protects kidney from injury or potentiates this process, depending on which HDAC (s) isform is suppressed, whereas inhibition of histone methyltransferase, generally provides a protective effect in AKI. Although AKI is also associated with changes in DNA methylation, the role of DNA methylation in kidney injury remains unclear. In this article, we discuss the role and mechanism of histone acetylation and methylation in the pathogenesis of AKI. PMID- 30298651 TI - Raising awareness, screening and prevention of chronic kidney disease: It takes more than a village. AB - Chronic kidney disease (CKD) is a major public health problem worldwide. Its prevalence and incidence are increasing, particularly among the ethnic minority populations. Diabetes, hypertension and obesity have been the three major aetiologies for CKD in all developed countries. While diabetes and hypertension remain the major causes of CKD in developing countries, environmental pollution, pesticides, water, analgesic abuse and herbal medications are common causes in these regions. Rapid urbanization and globalization are thought to be the contributing factors to rising prevalence and incidents of CKD. Despite the rising prevalence of CKD, disease awareness remains profoundly low. Worldwide, only 6% of the general population and 10% of the high-risk population are aware of their CKD statuses. Health screenings have been shown to be effective in improving the incidence of ESRD. However, currently there is no effective tool to assess and evaluate the awareness objectively. PMID- 30298652 TI - Perspectives on acute kidney injury strategy: Hong Kong. AB - Acute kidney injury is a common condition in hospitalized patients and a strong predictor of short-term morbidity and mortality. In this article, local epidemiological data on the prevalence and outcome of acute kidney injury amongst hospitalized patient in a tertiary referral center were discussed. The latest practice guidelines endorsed by the Hong Kong College of Physicians will be discussed, with emphasis on local practical issues and problems of guideline implementation. PMID- 30298653 TI - Complement in glomerular diseases. AB - Complement activation has been identified to play a vital role in the pathogenesis of many glomerulonephritis, either as direct complement activation driven factor in thrombotic microangiopathy and C3 glomerulopathy, and/or as an important contributor in lupus nephritis and anti-neutrophil cytoplasmic antibody associated vasculitis. Recent studies indicated that complement activation may also play roles in the pathogenesis of immunoglobulin A nephropathy and focal segmental glomerulosclerosis. Interestingly, monoclonal immunoglobulins/light chains from patients with monoclonal gammopathy may interfere with complement activation and thus indirectly result in complement-mediated glomerulonephritis. Understanding of the pathogenic roles of complement activation in various glomerulonephritis will facilitate the identification of potential novel therapeutic targets in complement system. PMID- 30298654 TI - New insights into the role and mechanism of Wnt/beta-catenin signalling in kidney fibrosis. AB - Wnt/beta-catenin is an evolutionarily conserved, developmental signalling pathway that regulates embryogenesis, injury repair and pathogenesis of human diseases. Dysregulated activation of Wnt/beta-catenin is associated with the development and progression of renal fibrotic lesions after injury. Wnt are induced and beta catenin is activated in various models of experimental chronic kidney disease (CKD) and in human nephropathies. Recent findings indicate that pro(renin) receptor is an amplifier of Wnt/beta-catenin by acting as a downstream target and an obligatory component for its signal transduction. Genetic blockade of Wnt secretion in a cell type-specific manner uncovers renal tubular epithelium as the major source of Wnt ligands in CKD. Wnt/beta-catenin controls the expression of a wide variety of downstream mediators implicated in kidney fibrosis, such as fibronectin, Snail1, matrix metalloproteinase-7, hepatocyte growth factor and various components of the renin-angiotensin system. Targeted inhibition of Wnt/beta-catenin is able to ameliorate kidney fibrotic lesions in pre-clinical settings. In this review, we summarize recent advances in our understanding of the regulation, signal transduction, role and mechanisms of Wnt/beta-catenin signalling in the pathogenesis of kidney fibrosis. We also discuss the therapeutic potential of targeting this pathway for the treatment of fibrotic CKD. PMID- 30298655 TI - Role of C-reactive protein in the pathogenesis of acute kidney injury. AB - Acute kidney injury (AKI) is characterized by both non-inflammatory and inflammatory process, and accumulating evidence has demonstrated that inflammation plays a key role in the pathogenesis and progression of AKI. C reactive protein (CRP), an acute reactant produced by liver and many inflammatory cells, acts not only as an inflammation biomarker, but also as a pathogenic factor for AKI. Indeed, increased concentration of CRP is associated with poor outcome of varied etiologically related AKI patients. In recent years, the role of CRP is gradually recognized as an active participant in the pathogenesis and progression of AKI by exacerbating local inflammation, impairing the proliferation of damaged tubular epithelial cells and promoting fibrosis of injured renal tissue. PMID- 30298657 TI - Perspectives on acute kidney injury strategy in China. AB - Acute kidney injury (AKI) has imposed a heavy disease burden in China, with substantial underdiagnosis and undertreatment. The incidence, cause and outcome of patients with AKI vary according to different geographic regions and economic development status; therefore, regional improvement strategies are needed. Defining the etiology of AKI is critical in making the proper therapeutic regimen, and a multidisciplinary cooperative AKI team is essential in order to establish the early diagnosis and proper management of patients with AKI. PMID- 30298656 TI - Salt, water and nephron: Mechanisms of action and link to hypertension and chronic kidney disease. AB - Our knowledge on sodium and water homeostasis and regulation continues to evolve. A considerable amount of new information in this area has emerged in recent years. This review summarizes existing and new literature and discusses complex multi-organ effects of high-salt and low-water intake and role of arginine vasopressin in this process, as well as the potential clinical significance of non-osmotic sodium storage pool and rhythmicity of urine sodium excretion. It has become clear that sodium and water dysregulation can exert profound effects on kidney and vascular health, far greater than previously recognized. Maladaptation to a combined high-salt and low-water intake can be linked to the growing epidemic of hypertension and chronic kidney disease. PMID- 30298658 TI - Lupus nephritis: An update on treatments and pathogenesis. AB - Immunosuppressive therapies for lupus nephritis (LN) have improved significantly over the past few decades, resulting in growing number of choices for treatment individualization and improved renal and patient outcomes. Corticosteroids combined with mycophenolate or cyclophosphamide induces a satisfactory response in a high proportion of Asian and Caucasian patients, but the rate of improvement varies considerably between patients. Relatively low disease flare rate was observed in Chinese patients receiving low-dose prednisolone and mycophenolate maintenance. Short-term results with calcineurin inhibitors (CNI) are encouraging, attributed both to their immunosuppressive efficacy and the action of these agents on podocyte biology leading to more rapid proteinuria suppression. Additional data, especially on the avoidance of nephrotoxicity and metabolic side effects, is required to facilitate selection of patients appropriate for this treatment. Modifications of standard regimens such as reducing corticosteroid exposure or using enteric-coated mycophenolate might help reduce treatment-related toxicities without compromising efficacy. While clinical outcomes of patients have improved with recent therapeutic advances, individual and ethnic variations in disease manifestations and treatment response, as well as the prevention of infections and long-term complications still present challenges to frontline clinicians. Recent data from histological examination and translational studies also suggest that complement activation via the alternative pathway, immune deposition on renal tubular basement membrane, and local inflammatory responses involving resident kidney cells are of pathogenic relevance in LN. The progress of clinical and translational studies has improved not only the understanding of disease mechanisms but also clinical decision making in the management of LN. PMID- 30298659 TI - Taiwan renal care system: A learning health-care system. AB - Taiwan renal care system is an evolving learning health-care system. There are four facets of this system. From the early history of dialysis and Taiwan Renal Registry Data System, it facilitates the generation of data to knowledge. National multidisciplinary pre-end-stage renal disease care project and outcome enhances knowledge to practice. Early chronic kidney disease (CKD) programs and 2015 Taiwan CKD clinical guidelines implicate the practice to customer, and then explore the causes of CKD help to resume customer to data. A learning health-care system allows better and safer care at lower cost, enhancement of public health and patient empowerment. The successful development of a learning health-care system was to collect, accumulate and analyze data, interpret results, deliver tailored message and take action to change practice. Through the established database and data analysis, an integrated care system would be able to improve clinical outcomes and achieve the most cost-effectiveness care. Acute kidney injury, CKD with unknown origin, palliative care and kidney transplant are our new focuses to struggle. PMID- 30298660 TI - How to treat patients with chronic kidney disease: With special focus on IgA nephropathy. AB - Chronic kidney disease has become a worldwide problem. Among chronic kidney disease patients, IgA nephropathy is common in the world. Serum levels of galactose deficient (Gd)-IgA1 and Gd-IgA1-specific antibodies are elevated in most IgA nephropathy patients. Glomerular Gd-IgA1 deposition has been observed by immunofluorescence. There are many reports that the anti-proteinuric effect is significantly greater in groups who receive tonsillectomy with steroid pulse therapy in IgA nephropathy patients. Furthermore, patients with tonsillectomy with steroid pulse therapy have shown a strong down-regulation of delta serum IgA/C3 per year and have conserved their renal function. New treatments, that is, Atacicept and glucocorticoid budesonide, have been developed for this disease. PMID- 30298661 TI - Update on treatment of immunoglobulin A nephropathy. AB - Immunoglobulin A nephropathy (IgAN) is the most common form of primary glomerulonephritis worldwide and the most common cause of end-stage renal disease in young adults. However, there are still no specific therapies capable of targeting key pathways involved in disease pathogenesis. Recently, many large randomized controlled trials have been reported, such as Supportive Versus Immunosuppressive Therapy for the Treatment of Progressive IgA Nephropathy, Targeted-release Budesonide Versus Placebo in Patients with IgA Nephropathy and Therapeutic Evaluation of Steroids in IgA Nephropathy Global, which are considered to update the 2012 Kidney Disease: Improving Global Outcomes Guideline. More importantly, with a deeper understanding of the roles of mucosal immunity, B-cell activation and complement activation in IgAN, the studies of targeting pathogenic pathways are ongoing. In this review, by systemically searching the clinical trials in IgAN on ClinicalTrials.gov (https://clinicaltrials.gov/), we update the evidence for corticosteroids/immunosuppressive therapy in IgAN and explore the promising targeting pathogenic pathway therapeutic options. With better understanding of pathogenesis of IgAN, emerging therapies will soon become a reality in future. PMID- 30298662 TI - Chronic kidney disease epidemic: How do we deal with it? AB - Chronic kidney disease (CKD) is a leading cause of mortality and morbidity around the world. The prevalence of CKD increases steadily over the past decade in parallel to the rapid expansion of diabetic population. Apart from increased mortality, CKD also has significant impact on quality of life and the economy. The approach to deal with the global CKD epidemic is multifaceted. Early detection by screening high-risk individuals such as those with hypertension and diabetes is important and cost-effective. However, low CKD awareness in many countries may impose barriers to early intervention. Hence raising CKD awareness among public and policy makers should be encouraged. In addition, the use of peritoneal dialysis, a less costly and home-based dialysis modality compared with in-center haemodialysis, should be promoted to maximize access to dialysis with limited resources. Finally, ongoing research and clinical trials through international collaborations could provide further insight into the pathophysiology of CKD progression, and establish the foundation for development of specific therapeutic agents to retard progression to end stage renal failure. PMID- 30298663 TI - Mineral bone disorders in chronic kidney disease. AB - As the GFR loss aggravates, the disturbed mineral metabolism worsens the bone microstructure and remodelling - scenario, which is known as CKD-mineral bone disease (MBD). CKD-MBD is characterized by : (i) abnormal metabolism of calcium, phosphorus, parathyroid hormone (PTH), or vitamin D; (ii) abnormalities in bone turnover, mineralization, volume linear growth or strength; (iii) soft-tissue calcifications, either vascular or extra-osseous. Uremic vascular calcification and osteoporosis are the most common complications related to CKD-MBD. Disregulated bone turnover by uremic toxin or secondary hyperparathyroidism disturbed bone mineralization and makes it difficult for calcium and inorganic phosphate to enter into bone, resulting in increased serum calcium and inorganic phosphate. Vascular calcification worsens by hyperphosphatemia and systemic inflammation. Since vitamin D deficiency plays an important role in renal osteodystrophy, supplement of nutritional vitamin D is important in treating uremic osteoporosis and vascular calcification at the same time. Its pleotropic effect improves the bone remodeling initiated by osteoblast and alleviates the risk factors for vascular calcification with less hypercalcemia than vitamin D receptor analogs. Therefore, nutritional vitamin D should be considered in managing CKDMBD. PMID- 30298664 TI - CKD prevention: Perspectives in Hong Kong. AB - Hong Kong experiences a progressive rise in the prevalence of treated end-stage renal disease (ESRD) as recorded by the Hong Kong Renal Registry managed by the Hospital Authority (HA) that takes care of 90 - 95% of the ESRD burden. The CKD burden is envisaged to be high, as reflected by 2 initiatives - SHARE which detected a high prevalence of urine or blood pressure abnormalities among 1,201 asymptomatic individuals who underwent screening, and RISKS that aimed to further characterize the spread of CKD in the asymptomatic population. For CKD prevention, two statutory bodies - the HA and Hong Kong College of Physicians (HKCP), and two non-governmental organizations - Hong Kong Society of Nephrology (HKSN) and Hong Kong Kidney Foundation (HKKF), all have a role to play. The Central Renal Committee (CRC) operated under HA co-produces with HKCP and HKSN a clinical practice guideline for the provision of renal service in Hong Kong which includes CKD care and prevention. HKSN now holds annual educational symposia and a Continuous Medical Education (CME) course in partnership with the HKCP and Asian Pacific Society of Nephrology in addition to its Annual Scientific Meeting. The HKSN also provides a collective International Society of Nephrology (ISN) membership for all its full members to enhance education and other pertinent initiatives. For public education, the HKSN and HKKF participate in the annual World Kidney Day event and organize free blood pressure and CKD surveys in public housing estates to increase public awareness of CKD. The latter is also effected via regular promotion through the mass media. PMID- 30298665 TI - Genetic study of immunoglobulin A nephropathy: From research to clinical application. AB - Immunoglobulin A nephropathy (IgAN) is one of the most common primary glomerulonephritis throughout the world and a major cause of end-stage renal disease among East Asian population. It is widely considered that genetic factors play an important role in the pathogenesis of IgAN. The genetic studies of IgAN, is from the association studies of candidate genes and family-based designs, to the genome-wide association studies. Altogether there are five large genome-wide association studies performed, which have identified multiple susceptibility loci for IgAN, including several novel loci found in Chinese population. The discovery of these susceptibility loci has provided important insight into the potential biological mechanisms and pathways that influence genetic risk to IgAN. In addition, genetic interaction and structural variation (such as copy number variation) studies were also conducted to identify more variants associated with IgAN and disease progression. The genetic studies of IgAN have made great achievements in recent years. Most of susceptibility loci discovered up to date contain genes involved in the response to mucosal pathogens, suggesting that intestinal immune network for IgA production may be involved in the pathogenesis of IgAN. While the genetic studies of the complex diseases remain to be challenging, new genetic and analytical techniques and methods, especially next generation sequencing-based studies, need to be applied to advance the genetic studies of IgAN. More importantly, we need to identify the genetic factors which influence the clinical phenotypes and renal progression to end-stage renal disease. This will require the integration of genomic data with other omics profiles (e.g. transcriptomics, metabolomics and immunomics) in patients with long-term clinical follow-up data to better understand the factors underlying inter-individual variability, not only in disease susceptibility, but also in the long-term prognosis and healthcare requirements. PMID- 30298666 TI - Diet, gut microbiome and indoxyl sulphate in chronic kidney disease patients. AB - Emerging evidence suggests that intestinal dysbiosis plays an important role in host inflammation locally and systemically. Such pathological condition is even more prevailing in patients with chronic kidney disease (CKD). Of note, indoxyl sulphate (IS), a gut-derived uremic toxin, is notorious for its pro-inflammatory feature in CKD patients. IS accumulates in the body as the urinary excretion of uremic toxins is impaired, and further worsens the kidney function in a vicious cycle to CKD. Dietary restriction in vegetables, fruits and yogurt leads to the predominance of indole-producing intestinal microbial flora and further exaggerates the accumulation of IS in CKD patients. Recently, interventional studies have shown that circulating IS can be reduced by dietary prebiotic and/or probiotic supplements. However, further randomized controlled trials are warranted to examine whether such beneficial effect of dietary prebiotic/probiotic supplements could be extrapolated to better hard outcomes in CKD population. In this review, we would also like to emphasize the importance of achieving sufficient intake of dietary fibre by proper vegetable pre-treatment and accurate fruit selection, instead of directly avoiding these potassium-rich yet fibre-rich and base-producing foods. PMID- 30298667 TI - Advanced therapeutics in focal and segmental glomerulosclerosis. AB - Focal segmental glomerulosclerosis (FSGS) is a glomerulonephritis with podocyte injury. The renal prognosis of FSGS is relative poor. The overall remission rate of the FSGS patients with nephrotic syndrome to immunosuppressive treatments was reported as 47-66%, highlighting its therapeutic challenge-lacking in sufficient evidence-based interventions. In first-line treatment of nephrotic syndrome, daily oral prednisolone is a commonly used drug, whereas optimal treatment strategies, like indications and duration, remain controversial. Calcineurin inhibitor and cyclophosphamide are recommended in steroid-dependent/steroid resistant patients. However, the high unmet need in effective immunosuppressive treatments calls for the development of new therapy methods. Rituximab, a monoclonal antibody targeting CD20 B-cells, could increase the complete or partial remission rate, and decrease the relapse rate based on several previous studies on FSGS. In addition, the using of rituximab could potentially help the FSGS patients to stop the concomitant therapy include steroid and immunosuppressive agents. Other treatment options like adalimumab or abatacept also showed potential therapeutic effect, but still required larger Randomized Controlled Trial study to determine its efficiency and safety. Besides, expanding understanding of the genetic basis of FSGS is necessary to investigate new therapeutic agents. With the unsatisfied patients' outcome under the current treatments, innovation should be encouraged on the treatment strategy based on Kidney Disease: Improving Global Outcomes guideline and international collaborations are required for the potential novel immunosuppressive or immunomodulatory therapies. PMID- 30298668 TI - Role of Kruppel-like factor-2 in kidney disease. AB - Kruppel-like factor-2 (KLF2) is a transcription factor that plays a major role in the regulation of endothelial cell function. KLF2 protects against endothelial cell injury through its anti-inflammatory, anti-thrombotic and anti-angiogenic effects to maintain the normal vascular integrity. Our recent data indicate that KLF2 is down-regulated in glomerular endothelial cells of patients with diabetic kidney disease and that endothelial cell-specific reduction in KLF2 expression in experimental model of diabetic kidney disease exacerbates glomerular endothelial cell injury and accelerates the disease progression. KLF2 is a key transcriptional regulator of endothelial nitric oxide synthase, and its renoprotective function may be mediated through the increased endothelial nitric oxide synthase expression. As KLF2 expression is stimulated by shear stress, we also investigated the role of KLF2 in the nephrectomy mouse model, in which the endothelial KLF2 expression would be increased through glomerular hyperfiltration in the remnant kidney. Reduction of endothelial KLF2 led to increased glomerular endothelial cell injury and progressive kidney disease in uninephrectomized mice. Interestingly, KLF2 expression is also reduced in nephrectomy patients with progressive kidney disease as compared to those with the non-progressive disease. Together, these studies indicate a critical role of KLF2 in maintaining normal glomerular endothelial cell function and that deficiency of KLF2 leads to more progressive kidney disease. PMID- 30298669 TI - Role of renin-angiotensin system in acute kidney injury-chronic kidney disease transition. AB - Acute kidney injury (AKI) can increase the risk of developing incident chronic kidney disease (CKD). The severity, frequency and duration of AKI are crucial predictors of poor renal outcome. A repair process after AKI can be adaptive and kidney recovers completely after a mild injury. However, severe injury will lead to a maladaptive repair, which frequently progresses to nephron loss, vascular rarefaction, chronic inflammation and fibrosis. Although different mechanisms underlying AKI-CKD transition have been extensively discussed, no definite intervention has been proved effective to block or to retard the transition until recently. In CKD, renin-angiotensin system (RAS) inhibitor has been proved effective to slow down disease progression. Furthermore, RAS needs to be highlighted again in AKI-CKD transition because recent animal studies have shown the activation of intra-renal RAS after AKI, and RAS blockade can reduce the ensuing CKD and mortality. In patients with the complete renal recovery after AKI, administration of RAS inhibitor is associated with reduced risk of subsequent CKD as well. In this article, we will demonstrate the role of RAS in AKI-CKD transition comprehensively. We will then emphasize the promising effect of RAS inhibitor on CKD prevention in patients recovering from AKI based on evidence from the bench to clinical research. All of these discussions will contribute to the establishment of reliable monitoring and therapeutic strategies for patients with functional recovery from AKI who can be most easily ignored. PMID- 30298670 TI - Intraocular cytokine profile and autoimmune reactions in retinitis pigmentosa, age-related macular degeneration, glaucoma and cataract. AB - PURPOSE: To analyse intraocular cytokine levels and prevalence of intraocular antiretinal antibodies (ARAs) in patients with retinitis pigmentosa (RP), age related macular degeneration (AMD), glaucoma and cataract, and correlate the results to clinical manifestations. METHODS: We collected intraocular fluid samples from patients with RP (n = 25), AMD (n = 12), glaucoma (n = 28) and cataract (n = 22), and serum samples paired with the intraocular fluids from patients with RP (N = 7) and cataract (n = 10). Interleukin (IL)-1beta, IL-1ra, IL-2, IL-6, IL-6ralpha, IL-7, IL-8, IL-10, IL-17A, IL-23, thymus- and activation regulated chemokine (TARC), monocyte chemoattractant protein-1 (MCP-1), tumour necrosis factor-alpha (TNF-alpha), placental growth factor (PlGF) and vascular endothelial growth factor (VEGF) were measured using a multiplex assay. Antiretinal antibodies (ARA) detection was performed by indirect immunofluorescence. RESULTS: Increasing age was associated with increasing levels of IL-6, IL-8, TNF-alpha and VEGF. All patient groups exhibited distinct profiles of intraocular cytokines. Intraocular levels of IL-8 were highest in patients with AMD and glaucoma. Cataract patients exhibited high intraocular levels of IL 23. Intraocular levels of IL-2, IL-6, MCP-1 and PlGF in RP patients exceeded the levels of serum, indicating intraocular production. Intraocular ARAs were found in only one patient with AMD. CONCLUSION: Increased levels of inflammatory cytokines in intraocular fluid of patients with originally noninflammatory ocular diseases show that intraocular inflammation is involved in their pathogenesis of these entities. Moreover, we show that increasing age is associated with increasing levels of intraocular cytokines and conclude that future studies on intraocular mediators should be corrected for age of patients. PMID- 30298671 TI - Optimal sample size planning for the Wilcoxon-Mann-Whitney test. AB - There are many different proposed procedures for sample size planning for the Wilcoxon-Mann-Whitney test at given type-I and type-II error rates alpha and beta, respectively. Most methods assume very specific models or types of data to simplify calculations (eg, ordered categorical or metric data, location shift alternatives, etc). We present a unified approach that covers metric data with and without ties, count data, ordered categorical data, and even dichotomous data. For that, we calculate the unknown theoretical quantities such as the variances under the null and relevant alternative hypothesis by considering the following "synthetic data" approach. We evaluate data whose empirical distribution functions match the theoretical distribution functions involved in the computations of the unknown theoretical quantities. Then, well-known relations for the ranks of the data are used for the calculations. In addition to computing the necessary sample size N for a fixed allocation proportion t = n1 /N, where n1 is the sample size in the first group and N = n1 + n2 is the total sample size, we provide an interval for the optimal allocation rate t, which minimizes the total sample size N. It turns out that, for certain distributions, a balanced design is optimal. We give a characterization of such distributions. Furthermore, we show that the optimal choice of t depends on the ratio of the two variances, which determine the variance of the Wilcoxon-Mann-Whitney statistic under the alternative. This is different from an optimal sample size allocation in case of the normal distribution model. PMID- 30298673 TI - Impact of antioxidant treatment on DNA fragmentation index: a double-blind placebo-controlled randomized trial. AB - BACKGROUND: Previous reports on effect of antioxidants on sperm DNA integrity were equivocal, and there is a lack of randomized, placebo-controlled studies. OBJECTIVES: To evaluate the efficacy of combined antioxidant treatment in subfertile men with normal reproductive hormone levels and high sperm DNA fragmentation index (DFI). MATERIALS AND METHODS: This placebo-controlled, double blind, randomized study evaluated the effects of combined antioxidant treatment in 77 men from infertile couples, with normal testosterone, LH and FSH levels and DFI >=25%. All participants were randomly assigned to receive combined antioxidant treatment (vitamins, antioxidants and oligoelements) or placebo for six months. The primary outcome measured was DFI. Secondary outcomes were standard semen parameters. DFI and other semen parameters were, at each time point (pre-treatment, and after three and six months of treatment), compared between the treatment and the placebo group using Mann-Whitney U-test. RESULTS: Antioxidant group had higher sperm concentration after three months of treatment (median: 24.4 * 106 /mL vs. 27.2 * 106 /mL; P = 0.028) and borderline statistically significant higher concentration after six months of treatment (median: 24.4 * 106 /mL vs. 33.3 * 106 /mL; P = 0.053) compared to pre-treatment values. The DFI did not change during the 6 months of antioxidant therapy. No statistically significant difference between the antioxidant and placebo group was seen for any of the semen parameters including sperm DFI at any of the three time points. DISCUSSION: The increase in sperm concentration was more pronounced in the antioxidant treated group but not statistically significantly higher than among controls, perhaps due to insufficient statistical power. Previous studies have shown positive effect of antioxidant treatment on DFI and other semen parameters. However, our findings indicate that men with normal reproductive hormone levels may not be the primary target group for such therapy. CONCLUSION: Six months treatment with antioxidants had no effect on sperm DFI. PMID- 30298672 TI - Dual Use of Department of Veterans Affairs and Medicare Benefits on High-Risk Opioid Prescriptions in Veterans Aged 65 Years and Older: Insights from the VA Musculoskeletal Disorders Cohort. AB - OBJECTIVE: To examine the association of dual use of both Veterans Health Administration (VHA) and Medicare benefits with high-risk opioid prescriptions among Veterans aged 65 years and older with a musculoskeletal disorder diagnosis. DATA SOURCES/STUDY SETTING: Data were obtained from the VA Musculoskeletal Disorder (MSD) cohort and national Medicare claims data from 2008 to 2010. STUDY DESIGN: We conducted a retrospective analysis of Veterans enrolled in Medicare to examine the association of dual use with long-term opioid use (>90 days of prescription opioids/year) and overlapping opioid prescriptions. Multivariable logistic regression was performed adjusting for demographic and clinical characteristics. DATA COLLECTION/EXTRACTION METHODS: We identified 21,111 Veterans enrolled in Medicare who entered the MSD cohort in 2008 and received an opioid prescription in 2010. We linked VHA data with Medicare claims data to identify opioid prescriptions for these Veterans in 2010. PRINCIPAL FINDINGS: As compared to Veterans who used only VHA or Medicare, Veterans with dual use of VHA and Medicare were significantly more likely to be prescribed long-term opioid therapy (OR = 4.61 (95 percent CI 4.05-5.25) and were also found to have higher median number of opioid prescriptions and higher odds of overlapping opioid prescriptions in 1 year. Patients reporting moderate-to-severe pain, non-white race/ethnicity, and higher scoring on the Charlson comorbidity index had significantly higher odds of long-term opioid prescriptions. CONCLUSIONS: Among Veterans aged 65 years or older, dual use of both VHA and Medicare was associated with higher odds of long-term opioid therapy. Our findings suggest there may be benefit to combining VHA and non-VHA electronic health record data to minimize exposure to high-risk opioid prescribing. PMID- 30298674 TI - A Novel Approach to Improve Repair Bond Strength of Repaired Acrylic Resin: An in Vitro Study on the Shear Bond Strength. AB - PURPOSE: To evaluate the combined effect of mechanical surface treatment with intermediate bonding agents (methyl methacrylate [MMA] and silane coupling agents) and ZrO2 nanoparticle (nano-ZrO2 ) addition to repair material on the shear bond strength (SBS) of repaired denture bases. MATERIALS AND METHODS: Heat polymerized acrylic resin was used to fabricate 130 cylindrical blocks (15 mm * 10 mm) and divided into a control group without treatment (C, n = 10), and 3 repair groups (n = 40/group) divided into specimens treated with alumina blasting alone (AB), specimens blasted with alumina combined with silane coupling agent (AB + SCA), or combined with MMA-based composite bonding agent (AB + MA). Treated groups were further subdivided according to nano-ZrO2 concentrations into 0 wt%, 2.5 wt%, 5 wt%, and 7.5 wt% added to repair resin powder. Repair resin monomer and polymer were combined and packed on the repair area and then placed in a pressure pot at 37 degrees C for 15 minutes for polymerization. Shear bond test was performed using a universal testing machine. Scanning electron microscopy (SEM) was used to examine the effect of surface modifications on repair surfaces and to evaluate the topography of fracture surfaces. Tukey-Kramer multiple comparison test was used to detect significant differences between groups (p <= 0.05). RESULTS: SBS (MPa) of specimens treated with alumina blasting and application of intermediate agents were significantly higher than the control group (p < 0.05), while no significant differences were found between AB and control group (p > 0.05). Nano-ZrO2 addition significantly increased SBS except for AB, and 5%, 7.5% MA (p > 0.05). SEM evaluation showed that alumina blasting created rougher and more porous surfaces, while SCA and MA reduced the irregularities and fissures. CONCLUSION: Application of bonding agents to repair surfaces after alumina blasting improved the repair bond strength and proved to be a possible new adhesive method for denture repair. Moreover, nano-ZrO2 addition in combination with surface treatment improved the repair bond strength. PMID- 30298676 TI - Noise concerns of residents living in close proximity to hydraulic fracturing sites in Southwest Pennsylvania. AB - OBJECTIVE: Noise associated with nontraditional gas industry (NTGI) sites (e.g., hydraulic fracturing well pads, compressor stations, processing plants) may create disturbances and anxiety in rural populations. This study evaluated levels of concern among residents of Southwestern Pennsylvania residing near NTGI sites. DESIGN: Noise measurements were collected inside and outside residences, and surveys were administered to residents. RESULTS: Daytime instantaneous sound levels ranged between 45.0 and 61.0 dBA. Dosimeter studies recorded day-night levels (Ldn ) of 53.5-69.4 dBA outside and 37.5-50.1 dBA inside, exceeding United States Environmental Protection Agency guidelines. Respondents indicated the NTGI noise disturbed their sleep, and the majority of respondents (96%) reported being worried about their overall health as a result of the noise. CONCLUSIONS: Health care professionals serving rural areas impacted by hydraulic fracturing (fracking) should be aware of potential noise stressors on the populations they serve. PMID- 30298677 TI - Strategic ignorance and global governance: an ecumenical approach to epistemologies of global power. AB - How can we account for the role of ignorance and knowledge in global governance? It is a contention of earlier scholarship in international relations and political sociology that knowledge production is tightly coupled with rational action - regardless of whether knowledge widely influences different stakeholders or not. This scholarship equally tends to assume an ignorance-knowledge binary relationship that associates ignorance with powerlessness and knowledge with power. This is a view we dispute. Calling for a new approach to the study of ignorance and knowledge in international politics, our article builds on research from ignorance studies, science and technology studies and critical race theory to derive a novel typology of epistemologies of power in which truth and ignorance are defined and combined in a plurality of ways. Approaching differing epistemologies of power in the transnational realm in a general or 'ecumenical' manner, we identify weaknesses in earlier approaches to the study of knowledge production in global affairs, and present four new concepts: 'factual determinism', 'cynical realism', 'unseeing proceduralism' and 'hopeful constructivism'. Through this framework, our article calls for greater recognition of the constitutive role that ignorance plays in operations of power on a global scale.

AB - BACKGROUND: Limited studies have examined links between maternal methyl donor (MET) supplementation and the growth-development characteristics of offspring, and possible underlying mechanisms for such links. This study investigated the effect of maternal or post-weaning MET-supplementation on growth performance, carcass characteristics, and meat quality of the finishing (d 180) offspring. Twenty-four sows were placed on a control (C) or MET-supplemented diet during pregnancy and lactation. Forty-eight female offspring were fed the control or MET supplemented diet from weaning to 6 months of age, resulting in four study groups (six litters per group): C/C, C/MET, MET/C, and MET/MET. RESULTS: Maternal MET supplementation increased average daily gain (ADG), body weight (BW), lean percentage and longissimus dorsi (LD) of the offspring at day 180 (P < 0.05), and upregulated the myosin heavy chain IIx, myogenic differentiation and muscle regulatory factor 4 mRNA levels in the LD muscle (P < 0.05). Meanwhile, offspring from maternal MET-supplementation exhibited a higher pH24h post mortem and superoxide dismutase activity, a lower L* 45min , glycolytic potential, malonaldehyde content in the LD muscle, and plasma homocysteine concentration (P < 0.05). CONCLUSION: Maternal MET-supplementation has a remarkable effect on growth performance, carcass traits, and meat quality of the offspring, which is associated with increased expression levels of myogenic genes and anti-oxidant capacity.

AB - INTRODUCTION: Epstein-Barr virus (EBV) associated smooth muscle tumors (EBV-SMT) are a rare complication of solid organ transplantation (SOT). Incidence data related to this EBV-SMT are limited. EBV DNA is universally present in these tumors. How these cells get infected with EBV, whether this is a result of primary EBV infection vs reactivation, and how persistent active EBV infection post-transplant influences EBV-SMT pathogenesis remains unknown. METHODS: Among 5006 SOT recipients (474 pediatric, 4532 adult) receiving SOT at our center between Jan 1984 and Dec 2015, three cases of post-transplant EBV-SMT were identified. RESULTS: All cases were pediatric heart transplants who were EBV seronegative prior to transplant, and experienced primary EBV infection with persistently elevated EBV viral loads, despite antiviral therapy. Two are deceased at 3.2 and 0.9 years post-diagnosis, while one remains alive 6.2 years post diagnosis. The overall local incidence of post-transplant EBV-SMT at our institution was 0.7 (95% CI, 0.2-1.7) per 1000 patient years, and 2.6 (95% CI, 0.6-6.7) per 1000 patient years in pediatric heart transplants. A literature review identified 36 pediatric and 51 adult cases of post-transplant EBV-SMT. CONCLUSIONS: We hypothesize that pre-transplant EBV seronegativity, followed by primary EBV infection and persistently high EBV viral loads, represents a unique risk factor for post-transplant EBV-SMT. Pediatric heart transplant recipients were found to be disproportionately affected by post-transplant EBV-SMT at our institution. PMID- 30298679 TI - Assessment of oral health status of children with epilepsy: A retrospective cohort study. AB - BACKGROUND: Epileptic children are liable to experience oral health problems either due to the disease itself or medications administered to control the condition. AIM: We aimed to investigate caries experience, gingival health and oro-facial traumatic injuries in a sample of epileptic Egyptian children. DESIGN: A retrospective cohort study was conducted from September 2016 to April 2017 using data from medical records in Children Hospital at Ain Shams University. Dental examination was performed for 100 epileptic children and 80 healthy subjects who matched in age, gender, and socio-economic status. Caries experience was measured using the decayed, missing and filled teeth (DMFT or dmft) index and gingival index (GI) of Loe and Sillness was used to determine gingival health status. Oro-facial injuries were assessed using the WHO classification of trauma. Quantitative data were presented as mean, SD, and 95% CI values. Qualitative data were presented as frequencies and percentages and the significance level was set at P <= 0.05. RESULTS: The mean +/- SD GI for epileptic children was significantly higher (1.16 +/- 0.42) than that of healthy children. (1.01 +/- 0.11) Healthy subjects had significantly lower mean dmf index scores 2.2 +/- 2.6 compared to epileptic subjects where mean dmf scores were 4.1 +/- 2.1. No significant difference, however, was detected between the two groups regarding caries experience in permanent dentition or incidence of oro-facial injuries. CONCLUSIONS: Epileptic children are highly burdened with gingival problems and liable to develop dental caries especially in primary dentition. Oral traumatic injuries, however, are not common complications if seizure attacks are well controlled. PMID- 30298680 TI - Lipid and color stability of the meat and sausages of broiler fed with calcium anacardate. AB - BACKGROUND: Anacardic acid, a phenolic compound, represents 90% of cashew nut shell liquid, which is a byproduct from the industrial processing of cashew nuts. This study aimed to add calcium anacardate (CA) to broilers' diets as a source of anacardic acid, to evaluate its antioxidant effect in breast meat and in processed meat products (sausages). For this purpose, birds were fed according to the following treatments: diet without antioxidant and diets containing 2.5, 5.0, 7.5, or 10.0 g kg-1 CA. Chicken breast meat was stored frozen for 90 days. The thigh and drumsticks were used to produce chicken sausages that were kept in refrigerated conditions for 90 days. Lipid oxidation and color stability were assessed every 30 days. RESULTS: For breast meat, a 2.5 g kg-1 concentration of CA was insufficient to retard lipid oxidation, whereas 10.0 g kg-1 gave rise to a pro-oxidant effect and 5.0 g kg-1 slowed the oxidation up to 50 days. A level of 7.5 g kg-1 of CA was effective in retarding oxidation, favoring colour stability during the 90-days frozen storage. For sausages, 2.5 g kg-1 of calcium anacardate in broiler diets was sufficient to retard lipid oxidation. Calcium anacardate 7.5 g kg-1 provided greater redness in the sausages compared with the control and with the other treatments containing 5.0 and 10.0 g kg-1 . CONCLUSIONS: Calcium anacardate is a potential natural antioxidant for breast meat and sausages in storage when added to broilers' diets. (c) 2018 Society of Chemical Industry. PMID- 30298681 TI - Effects of dietary supplemental methionine source and betaine replacement on the growth performance and activity of mitochondrial respiratory chain enzymes in normal and heat-stressed broiler chickens. AB - This study aimed to evaluate the effects of dietary supplemental methionine (Met) source and betaine (Bet) replacement for Met on performance and activity of mitochondrial respiratory chain enzymes (MRCEs) in normal and heat-stressed broiler chickens. Total of 1,200-day-old Ross 308 chicks were allocated to two houses, each consisted of 12 treatments, five replicates of 10 birds each with 2 * 2*3 * 2 (temperature * Met source * Met level * Bet, respectively) split-plot factorial arrangement. Met level in the basal diets was 70% requirements (Req) that was increased to the requirement or 130% by supplemental dl- or l-Met. Bet was or was not substituted at the rate of 30% supplemental dl- or l-Met. Feed conversion ratio (FCR) in chicks fed 70% l-Met was lower than those fed 70% dl Met diet during 1-10 days (p = 0.04). Broilers fed diets containing requirement or 130% Met, regardless of its source, showed higher weight gain (WG) than those received 70% Met diet during 11-42 days (p < 0.001). Feed intake (FI) of broilers fed 130% Met diet was decreased compared to other two groups during 11-42 days (p < 0.05). One hundred thirty percent Met requirement diet resulted in lower FCR comparing to other two groups during 11-42 days (p < 0.001). Heat-stressed birds grew less than those under normal condition (p < 0.05). Broilers fed Req Met diet under normal temperature exhibited higher activities of complexes (Cox) I and III (p < 0.05). Cox I activity in heat-stressed birds fed Bet + diet was similar to those fed Bet-diet under normal temperature (p = 0.046). It is concluded that performance and the activities of Cox I and III were increased as the level of Met increased. Bet replacement for 30% supplemental Met resulted in similar consequences comparing to non-Bet replacement diets on performance, but increased the activity of Cox III. l-Met was effective than dl-Met at the cellular level. High ambient temperature depressed performance and MRCE activity. PMID- 30298682 TI - Characterisation of the in vivo interactions between detomidine and methadone in horses: Pharmacokinetic and pharmacodynamic modelling. AB - BACKGROUND: Pharmacokinetic (PK)/pharmacodynamic (PD) modelling offers new insights to design protocols for sedation and analgesia in standing horses. OBJECTIVES: To evaluate the parameters and interactions between detomidine and methadone when given alone or combined in standing horses. STUDY DESIGN: Randomised, placebo-controlled, blinded, crossover. METHODS: Eight adult healthy horses were given six treatments intravenously: saline (SAL); detomidine (5 MUg/kg bwt; DET); methadone (0.2 mg/kg bwt; MET) alone or combined with detomidine (2.5 [MLD], 5 [MMD] or 10 [MHD] MUg/kg bwt). Venous blood samples were obtained at predetermined times between 0 and 360 min after drug administration. Plasma detomidine and methadone were measured using a single, liquid/liquid extraction technique by liquid chromatography coupled with a triple quadrupole mass spectrometer (LC-MS/MS). Sequential PK/PD modelling compared rival models, with and without PK and PD interaction between drugs, to fit the PD data including height of the head above the ground (HHAG), a visual analogue scale for sedation (VAS), electrical (ET), thermal (TT) and mechanical (MT) nociceptive thresholds and gastrointestinal motility (GIM) . RESULTS: Two and three compartment models best described the PK of detomidine and methadone, respectively. Detomidine decreased its own clearance as well as the clearance of methadone. The interaction of methadone on the effect of detomidine revealed an infra-additive (partial antagonism) effect for HHAG (alpha = -1.33), VAS (alpha = -0.98) and GIM (alpha = -1.05), a positive potentiation for ET (pot = 0.0041) and TT (pot = 0.133) and a synergistic to additive effect for MT (alpha = 0.78). MAIN LIMITATIONS: This is a small experimental study. CONCLUSIONS: Different PK/PD interactions were demonstrated for each PD parameter and could be modelled in vivo. The modelling of our data will allow us to simulate and predict the effect of constant rate infusions of both drugs for future investigations. PMID- 30298684 TI - Bioprosthetic aortic valve leaflet disruption with high energy electrocautery to prevent coronary artery obstruction during valve-in-valve transcatheter aortic valve replacement. AB - Transcatheter aortic valve replacement (TAVR) is well-established for the treatment of bioprosthetic aortic valve stenosis (AS) in high surgical risk patients. Coronary artery obstruction from displacement of the bioprosthetic valve leaflets during valve-in-valve (VIV) TAVR is a rare, but potentially fatal, complication. Recently, the bioprosthetic aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction (BASILICA) procedure was developed as a method for disrupting bioprosthetic leaflets in patients undergoing VIV TAVR at high risk for coronary obstruction. This case describes a successful VIV TAVR utilizing a simplified concept of the BASILICA technique in a patient where the full procedure could not be completed. PMID- 30298683 TI - Characterization and development of SAPP as a specific peptidic inhibitor that targets Porphyromonas gingivalis. AB - Porphyromonas gingivalis is a keystone bacterium in the oral microbial communities that elicits a dysbiosis between the microbiota and the host. Therefore, inhibition of this organism in dental plaques has been one of the strategies for preventing and treating chronic periodontitis. We previously identified a Streptococcal ArcA derived Anti-P gingivalils Peptide (SAPP) that in vitro, is capable of repressing the expression of several virulence genes in the organism. This leads to a significant reduction in P gingivalis virulence potential, including its ability to colonize on the surface of Streptococcus gordonii, to invade human oral epithelial cells, and to produce gingipains. In this study, we showed that SAPP had minimal cytotoxicity to human oral keratinocytes and gingival fibroblasts. We observed that SAPP directly bound to the cell surface of P gingivalis, and that alterations in the sequence at the N terminus of SAPP diminished its abilities to interact with P gingivalis cells and repressed the expression of virulence genes. Most strikingly, we demonstrated using an ex-vivo assay that besides its inhibitory activity against P gingivalis colonization, SAPP could also reduce the levels of several other oral Gram negative bacteria strongly associated with periodontitis in multispecies biofilms. Our results provide a platform for the development of SAPP-targeted therapeutics against chronic periodontitis. PMID- 30298685 TI - In-hospital opioid consumption, but not pain intensity scores, predicts 6-month levels of pain catastrophizing following hepatic resection: A trajectory analysis. AB - BACKGROUND: The study aims were to model acute pain intensity and opioid consumption trajectories up to 72 hr after open hepatic resection, identify predictors of trajectory membership and examine the association between trajectory memberships and 6-month pain and psychological outcomes. This is a long-term analysis of a published randomized controlled trial on the impact of medial open transversus abdominis plane catheters on post-operative outcomes. METHODS: A total of 152 patients (89 males; mean age 63.0 [range: 54-72]) completed questionnaires on pain and related characteristics pre-operatively and 6 months post-operatively. Total opioid use was recorded several times over a 72 hr period while self-reported pain intensity scores were collected multiple times until hospital discharge. Analyses were carried out using growth mixture modelling, logistic regression and general linear models. RESULTS: Both pain intensity and opioid consumption showed that a four-trajectory model best fits the data. Patients in the lowest opioid consumption trajectory were more likely to be classified in the constant mild pain intensity trajectory. Age and baseline levels of anxiety significantly predicted opioid trajectory membership while baseline depressive symptoms significantly predicted pain intensity trajectory membership. Patients in the two highest opioid consumption trajectories reported significantly higher levels of pain catastrophizing at 6 months compared to patients in the other 3 trajectories (all p < 0.05). CONCLUSION: High consumption of opioids after surgery is associated with higher levels of pain catastrophizing 6 months later. Identification of patients within these trajectories may lead to the development of early interventions targeted to high risk individuals. SIGNIFICANCE: Differences in initial levels of opioid consumption and rates of change in opioid consumption shortly after surgery can help predict long-term psychological responses to pain. Identifying key characteristics associated with initial opioid consumption can lead to the development of cost-effective early interventions targeted to high risk individuals. PMID- 30298686 TI - A Simple Screening Tool to Predict Outcomes in Older Adults Undergoing Emergency General Surgery. AB - OBJECTIVES: To determine whether the Flemish version of the Triage Risk Screening Tool (fTRST) can be used to accurately assess frailty in an emergency setting. DESIGN: Prospective observational study. SETTING: of a tertiary referral hospital. PATIENTS: All individuals aged 70 and older consecutively admitted to the emergency surgery unit with an urgent need for abdominal surgery between December 2015 and May 2016 who met inclusion criteria (N=110). MEASUREMENTS: Individuals were screened with the fTRST and additional metrics such as the age adjusted Charlson Comorbidity Index and American Society of Anesthesiology score. Thirty- and 90-day postoperative complications where recorded. Regression analyses were performed to identify possible preoperative predictors of adverse outcomes. RESULTS: Thirty-day major complications (Clavien-Dindo Classification 3 5) occurred in 28.2% of participants (n=31). fTRST had the highest correlation with major complications (odds ratio (OR) = 7.42). All participants who died within 30 days of surgery has a fTRST score of 2 or greater (area under the receiver operating curve (AUC)=71.3). When risk factors for overall 90-day mortality were analyzed, a fTRST score of 2 or greater had sensitivity of 96% (95% confidence interval CI=79.6-99.9%), specificity of 43.5% (95% CI=32.8-54.7%) (AUC=69.8%; OR=18.50, 95% CI=2.39-143.11, p = .005). The average length of hospital stay was more than twice as long in the group with a fTRST score of 2 or greater (15.2 days) than in those with a score less than 2 (6.6 days) (p = .005). CONCLUSION: The fTRST is an effective tool to predict mortality, morbidity, and length of stay after emergency surgery and can therefore be used to anticipate postoperative course, determine care goals, and plan for involvement of a dedicated geriatric care team. PMID- 30298687 TI - Normal Diffusivity of the Domestic Feline Brain. AB - Diffusion magnetic resonance imaging (MRI) provides useful information about neuroanatomy and improves detection of neuropathology. As yet a comprehensive evaluation of the diffusivity parameters within the feline brain has not been documented. In this study, we anesthetized and performed in vivo MRI on the brain of eight neurologically normal felines. A T1-weighted structural sequence with a resolution of 0.5mm3 and a parallel diffusion weighted sequence with 61 directions and a resolution of 1.5mm3 was obtained. After correction and processing the diffusion brain data were parcellated into 151 regions of interest using previously published priors. These regions were grouped according to their lobar location within the brain (frontal, occipital, temporal, parietal, thalamus, midbrain, cerebellum and white matter). The mean and standard deviation of fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (RD) and axial diffusivity (AD) for these 151 individual regions and lobar groups were calculated and averaged across participants, creating a comprehensive distribution range of diffusion tensor values. When regions were statistically evaluated, white matter had significantly higher FA and RD and lower AD and MD diffusivity parameters when compared to other regions. Additionally, thalamic regions had significantly higher FA values than parietal and occipital regions. This information will not only help inform feline neuroanatomy but will serve as a reference standard for future feline neuroimaging studies. This article is protected by copyright.

PMID- 30298689 TI - Antarctic heterotrophic bacterium Hymenobacter nivis P3T displays light-enhanced growth and expresses putative photoactive proteins. AB - Hymenobacter nivis P3T is a heterotrophic bacterium isolated from Antarctic red snow generated by algal blooms. Despite being non-photosynthetic, H. nivis was dominantly found in the red snow environment that is exposed to high light and UV irradiation, suggesting that this species can flourish under such harsh conditions. In order to further understand the adaptive strategies on the snow surface environment of Antarctica, the genome of H. nivis P3T was sequenced and analyzed, which identified genes putatively encoding for light-reactive proteins such as proteorhodopsin, phytochrome, photolyase and several copies of cryptochromes. Culture-based experiments revealed that H. nivis P3T growth was significantly enhanced under light conditions, while dark conditions had increased extracellular polymeric substances. Furthermore, the expression of several putative light-reactive proteins was determined by proteomic analysis. These results indicate that H. nivis P3T is able to potentially utilize light, which may explain its dominance on the red snow surface environment of Antarctica. ORIGINALITY-SIGNIFICANCE STATEMENT: The role of proteorhodopsin in heterotrophic bacteria is not well-characterized, as only a handful of proteorhodopsin-harbouring isolates were shown to have a light-enhanced phenotype through culture-based experiments to date. This is the first study that demonstrates light-stimulated growth and protein expression evidence of photoactive proteins for a non-marine psychrophile and for a member of the genus Hymenobacter. It is also the first study that provides comprehensive proteome information for this genus. This study presents significant results in understanding the adaptive mechanism of a heterotrophic non-photosynthetic bacterium thriving on the snow surface environment of Antarctica as well as demonstrating the role of light-utilization in promoting growth, possibly through proteorhodopsin. PMID- 30298690 TI - Reinforcement of variability facilitates learning in humans. AB - Studies with rats and pigeons showed that reinforcement of response variability improved learning of difficult response sequences. The results suggested that concurrent reinforcement of variability might be a helpful tool when educators or therapists attempt to teach individuals with learning difficulties. However, similar experiments with humans failed to confirm the results. In fact, in the human case, concurrent reinforcement of variability interfered with learning. The present experiment studied the same phenomenon with human participants in the context of a computer-based game. Our results were consistent with the nonhuman animal findings. When students in our experiment were concurrently reinforced for sequence variability, they were more likely than control participants to learn a difficult response sequence. We conclude that reinforcement of variability can facilitate learning-in humans as well as animals -and discuss possible reasons for the difference between our results and the previous human findings. PMID- 30298691 TI - Bioinformatic analysis reveals novel hub genes and pathways associated with hypertensive nephropathy. AB - AIM: Hypertensive nephropathy (HTN) is one of the leading causes of end-stage renal disease and is closely associated with inflammation and tubule-interstitial fibrosis. The molecular mechanism underlying HTN remains unclear. This study utilized bioinformatic analysis to identify the novel gene targets for HTN. METHODS: We downloaded the microarray data of GSE99325 and GSE32591 from Gene Expression Omnibus. The dataset comprised 20 HTN and 15 normal samples. The differentially expressed genes (DEGs) were identified, and then gene ontology (GO) enrichment was performed, and a GO tree was constructed by using clusterProfiler and ClueGO. In addition, a protein-protein interaction (PPI) network was established using the Search Tool for the Retrieval of Interacting Genes database and visualized by Cytoscape. The novel hub genes were validated in in vitro experiments. RESULTS: A total of 267 genes (117 up-regulated and 150 down-regulated genes) were identified as DEGs. GO analysis and the GO tree indicated that the DEGs were mainly associated with steroid hormone response and the extracellular matrix. Basing on the PPI network, we screened out several novel hub genes. Considering the findings and the literature review, we focused on and validated the DUSP1, TIMP1, FOS, and JUN genes, which may play significant roles in the pathogenesis of HTN. These findings were consistent with the bioinformatic results for the in vitro validation. CONCLUSION: This study identified for the first time novel hub genes with microarray data in HTN by using bioinformatic analysis and provided novel evidence and clues for future works.

AB - PURPOSE: Recent literature has shown the potential of high-resolution quantitative susceptibility mapping (QSM) with ultra-high field MRI for imaging the anatomy, the vasculature, and investigating their magnetostatic properties. Higher spatial resolutions, however, translate to longer scans resulting, therefore, in higher vulnerability to, and likelihood of, subject movement. We propose a gradient-recalled echo sequence with prospective motion correction (PMC) to address such limitation. METHODS: Data from 4 subjects were acquired at 7T. The effect of small and large motion on QSM with and without PMC was assessed qualitatively and quantitatively. Full brain QSM and QSM-based venograms with up to 0.33 mm isotropic voxel size were reconstructed. RESULTS: With PMC, motion artifacts in QSM and QSM-based venograms were largely eliminated, enabling-in both large- and small-amplitude motion regimes-accurate depiction of the cortex, vasculature, and other small anatomical structures that are often blurred as a result of head movement or indiscernible at lower image resolutions. Quantitative analyses demonstrated that uncorrected motion could bias regional susceptibility distributions, a trend that was greatly reduced with PMC. CONCLUSION: Qualitatively, PMC prevented image degradation because of motion artifacts, providing highly detailed QSM images and venograms. Quantitatively, PMC increased the reproducibility of susceptibility measures. PMID- 30298693 TI - Platelet Indices as a marker for early prediction of erectile dysfunction in diabetic patients. AB - Erectile dysfunction is one of the major concerns in diabetic patients. Platelet Indices including mean platelet volume, platelet count and platelet distribution width are important biomarkers for platelet activation and pathophysiology of atherothrombosis. Measurement of Platelet Indices may early predict erectile dysfunction in diabetic men. This study aimed to measure Platelet Indices in diabetic patients with erectile dysfunction and to correlate between them and erectile dysfunction especially of vasculogenic type. The study included 30 diabetic patients with diagnosed erectile dysfunction and 20 normal males as a control. Each patient was evaluated by history, International Index of Erectile Function-5, general and local examination, HbA1c, pharmaco-penile duplex ultrasonography and blood sample to measure Platelet Indices. Platelet distribution width and mean platelet volume were significantly higher in patients than controls (p < 0.001). Their levels were significantly higher in vasculogenic erectile dysfunction than other types (p < 0.001). No statistically significant association regards the platelet count (p > 0.05). We concluded that Platelet Indices are high in diabetic patients with erectile dysfunction especially those with vasculogenic aetiology. They can predict erectile dysfunction in diabetic men early, and so they may be considered as cheap, available and useful biomarker for early diagnosis of vasculogenic erectile dysfunction in diabetic patients. PMID- 30298694 TI - Bladder cancer surveillance in patients with spinal cord injuries. PMID- 30298695 TI - Is a pillow a risk factor for glaucoma? AB - PURPOSE: To study whether a clinically significant increase in intraocular pressure (IOP) occurs during simulated sleep conditions with the subject's head turned comfortably into a pillow (the simulated sleep position) and the effect of protective glasses on any such IOP rise. METHODS: A specially developed electronic epipalpebral pressure (EPP) sensor was attached to an eyelid of the right eye of all participants: 11 patients with primary open-angle glaucoma and 11 healthy volunteers. During calibration, mechanical pressure was applied to the EPP sensor taped to the lower eyelid and the IOP was measured simultaneously at the slit lamp by Goldmann applanation tonometry. The EPP was increased in a stepwise fashion to assess the relationship between EPP and IOP for each individual eye. Thereafter, EPP (with the sensor now taped to the upper eyelid) measurements were performed in the simulated sleep position, both with and without protective glasses. The EPP was determined in each individual eye, and the estimated IOP was then inferred from the established EPP/IOP relationship. RESULTS: In the simulated sleep position, the mean IOP increased by an estimated 19.6 mmHg (SD: 7.5; range 11.6-32.8; p < 0.0001) in the patient group and 28.0 mmHg (SD: 9.6; range 12.3-41.1); p < 0.0001) in the control group. When the subjects wore protective glasses, the mean estimated IOP decreased again by 16.3 mmHg (SD: 5.6; range 9.8-28.1; p < 0.0001) in the patient group and 25.1 mmHg (SD: 8.2; range 11.7-38.3; p = <0.0001) in the control group. CONCLUSION: Turning the head into a pillow gave a large and clinically significant increase in the estimated IOP in the simulated sleep position. With protective glasses, however, the increase in estimated IOP was almost absent. Therefore, protective shielding of the eyes during sleep may be a treatment option in glaucoma. PMID- 30298696 TI - Biallelic mutations in PMFBP1 cause acephalic spermatozoa. AB - The majority of men with defects in spermatogenesis remain undiagnosed. Acephalic spermatozoa is one of the diseases causing primary infertility. However, the causes underlying over half of affected cases remain unclear. Here, we report by whole-exome sequencing the identification of homozygous and compound heterozygous truncating mutations in PMFBP1 of two unrelated individuals with acephalic spermatozoa. PMFBP1 was highly and specifically expressed in human and mouse testis. Furthermore, immunofluorescence staining in sperm from a normal control showed that PMFBP1 localizes to the head-flagella junction region, and the absence of PMFBP1 was confirmed in patients harboring PMFBP1 mutations. In addition, we generated Pmfbp1 knock-out (KO) mice, which we found recapitulate the acephalic sperm phenotype. Label-free quantitative proteomic analysis of testicular sperm from Pmfbp1 KO and control mice showed 124 and 35 proteins, respectively, increased or decreased in sperm from KO mice compared to that found in control mice. Gene ontology analysis indicates that the biological process of Golgi vesicle transport was the most highly enriched in differentially expressed proteins, indicating process defects related to Golgi complex function may disturb formation of the head-neck junction. Collectively, our data indicate that PMFBP1 is necessary for sperm morphology in both humans and mice, and that biallelic truncating mutations in PMFBP1 cause acephalic spermatozoa.

AB - BACKGROUND: Phenylketonuria is a hereditary disease caused by the lack or deficiency of phenylalanine hydroxylase enzyme activity. Parents of children with phenylketonuria undergo significant stress during their childcare years. They are also responsible for controlling their children's dietary treatment and this may affect their quality of life. The purpose of this study was to investigate the relationship between stress and quality of life in parents of children with phenylketonuria. METHODS: The present cross-sectional study is a correlation analytical research performed on parents of children with phenylketonuria in Kerman province in Iran in 2017. In total, 124 parents were chosen by consensus method. Parents completed the perceived stress scale and quality of life (SF36). SPSS software version 18 (https://www.presidion.com/software/ibm-spss-trial downloads/) was used to analyze the data. RESULTS: Total scores of stress and quality of life were 28.81 +/- 8.74 and 45.97 +/- 21.22. There was a significant negative correlation between quality of life and perceived stress (p < 0.001 and rho = -0.58). CONCLUSION: Parents of children with phenylketonuria have moderate quality of life and relatively high stress. The medical community and authorities should take steps to improve the quality of life and reduce stress experienced by parents of children with phenylketonuria. PMID- 30298699 TI - Ensiling characteristics, in vitro rumen fermentation, microbial communities and aerobic stability of low-dry matter silages produced with sweet sorghum and alfalfa mixtures. AB - BACKGROUND: Silages produced with grass and legume mixtures may have positive associative effects on silage quality and animal performance when ruminants are fed the silages. The present study aimed to determine the preservation characteristics, in vitro rumen fermentation profile and microbial abundance of silages, produced with mixtures of sweet sorghum (SS) and alfalfa (AF) in different ratios: 100:0 (Control), 75:25 (SA25), 50:50 (SA50), 25:75 (SA75) and 0:100 (SA100) on a fresh weight basis. RESULTS: As the proportion of AF increased in the silages, pH, acetic acid, ammonia nitrogen and crude protein (CP) concentrations, and aerobic stability increased (P < 0.05), whereas lactic acid and neutral detergent fibre (NDF) and acid detergent fibre (ADF) concentrations decreased (P < 0.05). Increasing the proportion of AF in the silages, increased (P < 0.05) the in vitro degradability of dry matter and CP, as well as the proportions of genus Prevotella, but decreased (P < 0.05) the in vitro degradability of NDF (IVNDFD) and ADF (IVADFD) and proportions of Butyrivibrio fibrisolvens. Compared to the Control silage, SA25 silage had greater (P < 0.05) proportions of Fibrobacter succinogenes and Ruminococcus flavefaciens, IVNDFD, IVADFD, ruminal short chain fatty acids and microbial protein concentrations, as well as lower (P < 0.05) methane production. CONCLUSION: The silage produced with the SS to AF ratio of 75:25 was the most suitable for ruminants use as a result of the optimal balance of fermentation quality, feed-nutritional value and aerobic stability.

AB - OBJECTIVE: The impact of persistent left bundle-branch block (pLBBB) on long-term clinical outcome remains to be determined. BACKGROUND: New-onset of pLBBB occurs frequently after transfemoral aortic valve implantation (TAVI). METHODS: Seven hundred and seven consecutive patients who underwent TAVI were analyzed for baseline and procedural characteristics and clinical outcome in an up to 2-year follow-up. Patients were divided into either a group with pLBBB until hospital discharge or a group without LBBB. We performed propensity-score matching and analyzed baseline characteristics, procedural data and clinical outcome of both groups. Patients received balloon-expandable valves in 56.4%, mechanically expandable valves in 37.5%, and self-expandable valves in 6.3%. RESULTS: A new onset, pLBBB was observed in 47.5% of patients after TAVI. The implantation of a mechanically expandable valve was associated with higher rate of pLBBB (54.2% vs. 20.8%, P < 0.001), whereas implantation of a balloon-expandable valve was associated with lower incidence of pLBBB (39.8% vs. 73.1%, P < 0.001). Deeper ventricular implantation at left-coronary side led to higher rates of pLBBB (7.5 +/- 2.5 vs. 6.7 +/- 2.6 mm, P < 0.001). The occurrence of pLBBB was associated with higher rates of permanent pacemaker implantation (40.9% vs. 15.9%, P < 0.001). By multivariate analysis, implantation of a mechanically expandable valve (Boston Scientific Lotus valve) was identified as independent predictor of occurrence of pLBBB (odds ratio 4.7, confidence interval 3.2-7.0, P < 0.001). In the 2-year follow-up, there were no significant differences between "pLBBB" and "no LBBB"-groups regarding mortality and rehospitalization due to heart failure. CONCLUSIONS: The occurrence of pLBBB is associated with the choice of valve type and implantation depth and requires significantly higher rates of permanent pacemaker implantations. Importantly, there are no differences in the 2-year follow-up regarding mortality and rehospitalization due to heart failure. PMID- 30298701 TI - Comparison of stereotactic body radiotherapy versus metastasectomy outcomes in patients with pulmonary metastases. AB - BACKGROUND: We compared the treatment outcomes of stereotactic body radiotherapy (SBRT) and metastasectomy in patients with pulmonary metastases. METHODS: Twenty one patients received SBRT (total radiation doses 60 Gy in 3 fractions or 48 Gy in 4 fractions) and 30 underwent metastasectomy, most (93.3%) with wedge resection. The patients were followed for a median of 13.7 months. The tumor size in the SBRT group was larger than in the metastasectomy group (median 2.5 vs. 1.25 cm; P = 0.015). Patients with synchronous metastases were more likely to be treated with SBRT than with metastasectomy (P = 0.006). RESULTS: There was no significant difference in the local control rates of the treatment groups (P = 0.163). Progression-free survival (PFS) was longer in the metastasectomy than in the SBRT group (P = 0.02), with one and two-year PFS rates of 51.1% and 46% versus 23.8% and 11.9%, respectively. The one and two-year overall survival (OS) rates were 95% and 81.8% in the metastasectomy group and 79.5% and 68.2%, in the SBRT group, respectively. In multivariate analysis, synchronous metastasis was related to poor PFS, and tumor size was the most significant factor affecting OS. There were no significant differences in PFS and OS between treatment groups after dividing patients according to the presence or absence of synchronous metastases. CONCLUSIONS: SBRT is considered a suitable local modality against pulmonary metastases; however, patients with synchronous metastases are only likely to obtain a small benefit from local treatment with either SBRT or surgery.

AB - A method of synthesizing a directly connected 1,3a,6a-triazapentalene (TAP) ring system as a linearly bonded aromatic system with a planar form was established. Various TAP-dimers and a 2-alkyl-TAP-trimer were synthesized and their fluorescence properties were evaluated. Although the direct connection of the TAP ring with other TAP rings did not affect the fluorescence properties in diluted solvent, TAP-dimers showed unique fluorescence properties derived from the aggregation state under highly concentrated conditions. In particular, TAP-dimer 5 f showed aggregation-induced emission in highly concentrated solution, and 5 b showed typical mechanochromic fluorescence in the solid state despite their compact molecular size. PMID- 30298704 TI - Comparison of skin autofluorescence, a marker of tissue advanced glycation end products in peritoneal dialysis patients using standard and biocompatible glucose containing peritoneal dialysates. AB - BACKGROUND: Heat sterilisation of peritoneal dialysis (PD) dialysates leads to the generation of advanced glycation products (AGEs), which can then deposit in the skin and be measured by skin autofluorescence (SAF). Newer biocompatible dual chamber dialysates contain less AGEs. We wished to determine whether the use of these newer dialysates resulted in lower SAF. METHODS: SAF was measured using the AGE reader, which directs ultraviolet light, intensity range 300-420 nm (peak 370 nm) in patients established on PD for > 3 months using glucose containing dialysates. RESULTS: We screened 196 consecutive patients, and measured SAF in 150; 86(57.3%) male, median age 62 (53-71) years, median duration of PD treatment 17 (8.6-34.3) months. The median SAF was 3.48 (2.92-4.26) AU. The median SAF in the 57 (38%) patients prescribed biocompatible dual chamber bag dialysates was 3.39 (2.69-3.98) vs 3.5 (3.05-4.54) for those using standard dialysates (p=0.044). Although prescription of biocompatible fluids was associated with SAF on univariate analysis, but not on multivariable testing, SAF was independently associated with Stoke-Davies co-morbidity grade (beta 0.045, 95% confidence limits (CL) 0.015 to 0.075, p=0.002), log duration of PD therapy (beta 0.051, CL 0.001 to 0.101, p=0.045), white ethnicity (beta 0.066, CL 0.028 to 0.104, p=0.001), and negatively with serum albumin (beta -0.006, CL -0.008 to -0.004, p=0.014) CONCLUSIONS: Although SAF was lower in PD patients prescribed biocompatible dual chamber dialysates, on multivariable testing these dialysates were not independently associated with SAF. Other factors than PD fluid AGE content appear more important in determining SAF. This article is protected by copyright. All rights reserved. PMID- 30298703 TI - A 21.6 kDa tegumental protein of Clonorchis sinensis induces a Th1/Th2 mixed immune response in mice. AB - INTRODUCTION: Clonorchis sinensis is a major parasite affecting the Korea population. Despite the high infection rate and pathogenicity, very few studies have been conducted to investigate the immune responses against the proteins of C. sinensis. METHODS: In this study, in vitro immune response induced by a recombinant 21.6 kDa tegumental protein derived from C. sinensis (rCsTegu21.6) was confirmed in murine dendritic cells and T cells. For the in vivo analysis, each mouse was immunized three times. Total serum IgG and T cell cytokine production were determined by ELISA, while T cell proliferation was detected by a WST (Water-Soluble Tetrazolium salt)-1 assay. RESULTS: In vitro tests indicated that rCsTegu21.6 treatment increased the expression of surface molecules, such as CD40 (77%), CD80 (52%) and CD86 (46%), on murine dendritic cells and the secretion of cytokines (TNF-alpha, IL-6, IL-1beta, IL-10, and IL-12p70). Moreover, co-culturing dendritic cells activated by rCsTegu21.6 with allogenic T cells induced T cell proliferation over time. rCsTegu21.6 also stimulated specific antibody production and cytokine secretion [IL-2, IL-4, and interferon (IFN)-gamma)] from T cells following immunization in vivo. Notably, rCsTegu21.6 predominantly induced IgG1 production and secretion of the Th2 cytokine IL-4, regardless of the type of adjuvant used. CONCLUSION: These results serve as a foundation for the development of tegumental protein-based vaccines against C. sinensis. PMID- 30298705 TI - Outcomes of intraocular lens scleral fixation with the friction knot technique. AB - PURPOSE: To examine the clinical outcomes of intraocular lens (IOL) scleral fixation with the friction knot technique. METHODS: Retrospective case series of 152 eyes of 152 patients with inadequate capsular bag support operated with the friction knot IOL scleral fixation technique by a single surgeon. The fixated IOLs were one-piece or three-piece models all with open loop haptics. Main outcome measures were change in corrected distance visual acuity (CDVA) and postoperative complications. RESULTS: The mean follow-up time was 11.7 months (median 4.9, range 0.7-64.8). The mean logarithm of the minimum angle of resolution CDVA improved from preoperative 0.77 +/- 0.73 (Snellen 20/118 +/- 7.3 lines) to 0.44 +/- 0.56 (Snellen 20/55 +/- 5.6 lines) at the final visit (p < 0.001). The main postoperative complications were ocular hypertension (30.3%), uveitis-glaucoma-hyphaema syndrome (12.5%; UGHS), vitreous haemorrhage (11.2%) and retinal detachment (8.6%). Two (1.3%) cases of suture breakage were seen. In multivariate Cox regression analysis, age under 60 years [hazard ratio (HR) = 5.41; 95% confidence interval (CI) 1.95-15.01] and scleral fixated one-piece IOL (HR = 4.23; 95% CI 1.44-12.44) were found as significant independent risk factors for developing new UGHS. CONCLUSION: The friction knot technique provides a firm scleral fixation. Scleral fixation may successfully be utilized in dislocated three-piece IOLs with loop haptics. We recommend avoiding scleral fixation of one piece IOLs in young patients due to a high risk of UGHS. PMID- 30298706 TI - Intracellular oxygen mapping using a myoglobin-mCherry probe with fluorescence lifetime imaging. AB - Oxygen (O2) is one of the most important biometabolites. In abundance, it serves as the limiting terminus of aerobic respiratory chains in the mitochondria of higher organisms; in deficit, it is a potent determinant of development and regulation of other physiological and therapeutic processes. Most knowledge on intracellular and interstitial concentration ([O2]) is derived from mitochondria isolated from cells or tissue biopsies, providing detailed but nonnative insight into respiratory chain function. The possible loss of essential metabolites during isolation and disruption of the normal interactions of the organelle with the cytoskeleton may cause these data to misrepresent intact cells. Several optical methodologies were also developed, but they are often unable to detect heterogeneity of metabolic characteristics among different individual cells in the same culture, and most cannot detect heterogeneous consumption within different areas of a single cell. Here, we propose a noninvasive and highly sensitive fluorescence lifetime microscopy probe, myoglobin-mCherry, appropriate to intracellular targeting. Using our probe, we monitor mitochondrial contributions to O2 consumption in A549 nonsmall cell lung cancer cells and we reveal heterogeneous [O2] within the intracellular environments. The mitochondrial [O2] at a single-cell level is also mapped by adding a peptide to target the probe to the mitochondria. PMID- 30298707 TI - Detection of IgE autoantibodies in mucous membrane pemphigoid and their association with disease severity. AB - BACKGROUND: Mucous membrane pemphigoid (MMP) is an autoimmune disease characterized by scarring lesions at mucosal sites. Although the pathogenic role of specific IgG and/or IgA has been already demonstrated and the detection of these immunoglobulins is a criterion in the diagnosis of MMP, little is known about IgE role in this disease. Therefore, the main purpose of this study was to assess the presence of circulating and tissue-bound IgE in patients with MMP and their possible correlations with clinical presentation and disease course. METHODS: We conducted a retrospective study on 29 patients affected by MMP, recruited from a single centre. Direct and indirect immunofluorescence studies were assessed to analyse the presence of specific IgE directed against the basal membrane zone. For each patient, fluorescence data were compared to clinical features. RESULTS: Linear deposits of C3, IgG and IgA were present in 86.2%, 62% and 37.9% of cases respectively, while IgE linear deposits were detected in 17 out of 29 patients (58.6%) including one case with isolated IgE positivity. Circulating IgE and IgA anti-BMZ were present in 7 (24.1%) and 5 (17.2%) patients, respectively. Both the presence of circulating IgA and of tissue-bound IgE deposits correlated with disease activity index (P<0.014). CONCLUSIONS: Our results demonstrated the presence of IgE autoantibodies in MMP, particularly in more severe cases. Thus, IgE detection may represent an additional useful diagnostic tool in this disease.

PMID- 30298709 TI - Comparison of clinical and sonographic scores in hidradenitis suppurativa and proposal of a novel ultrasound scoring system. AB - BACKGROUND: Hidradenitis suppurativa (HS) is a chronic, inflammatory disease that presents with nodules, abscesses and fistulae affecting the apocrine gland bearing skin. Since few years, ultrasonography is used to better characterize HS skin lesions but comparison between clinical and sonographic scores has been made only in small series of patients. The aim is to assess concordance between clinical and sonographic scores in a larger cohort of HS patients. METHODS: We conducted a retrospective observational study on 140 HS patients comparing two clinical score systems, Hurley and HS-Physical Global Assessment (PGA), with two ultrasonographic scores, SOnographic Score of Hidradenitis Suppurativa (SOS-HS) and ultrasonographic HS-PGA, a novel ultrasound scoring system set up by our group. We used the weighted Cohen's Kappa statistic (k) to evaluate the agreement. RESULTS: Agreement between Hurley staging and SOS-HS was found in 61.4% of patients (weighted kappa 0.477), while agreement between clinical and ultrasonography HS-PGA scores was found in 35% of patients (weighted kappa 0.278), both findings suggesting a substantial disagreement. CONCLUSIONS: Our study demonstrated a relevant disagreement between clinical and ultrasonography scores. Ultrasonography discovered non-clinically evident HS lesions, notably fistulae. Taken together, the above findings may support the view, previously suggested in expert panel reports, on the higher sensitivity of ultrasonography compared to clinics in HS. PMID- 30298710 TI - Prostate specific antigen levels and proportion of biopsy positive cores are independent predictors of upgrading patterns in low risk prostate cancer. AB - BACKGROUND: To evaluate clinical factors associated with the risk of tumour upgrading patterns in low risk prostate cancer (PCA) patients undergoing radical prostatectomy. METHODS: In a period running from January 2013 to December 2016, 245 low risk patients underwent RP. Patients were classified into three groups, which included case with pathology grade group one (no upgrading pattern), two three (intermediate upgrading pattern), and four-five (high upgrading pattern). The association of factors with the upgrading risk was evaluated by the multinomial logistic regression model. It was used a receiver operating characteristic (ROC) curve and area under the curve (AUC) analysis to assess the efficacy of predictors. RESULTS: Overall, tumor upgrading was detected in 158 patients (67.3%). Tumour upgrading patterns were absent in 80 patients (32.7%), intermediate in 152 cases (62%) and high in 13 subjects (5.3%). Median prostate specific (PSA) levels and proportion of biopsy positive core (BPC) were higher in patients with intermediate (PSA = 6 ng/mL; BPC = 0.28) and high (PSA = 8.9 ng/mL; BPC = 0.33) than those without (PSA = 5.7 ng/mL; BPC = 0.17) and the difference was significant (PSA: p = 0.002; BPC: p = 0.001). When compared to not upgraded cases, higher BPC proportions were independent predictors of intermediate upgrading patterns (odds ratio, OR = 36.711; p < 0.0001; AUC = 0.613) while higher PSA values were independent predictors of high upgrading patterns (OR=2.033, p < 0.0001; AUC = 0.779). CONCLUSIONS: PSA and BPC were both independent predictors of tumour upgrading in low risk PCA. BPC associated with the risk of intermediate tumour upgrading patterns, but showed a low discrimination power. PSA associated with high upgrading patterns and showed a fair discrimination power in the model. Tumour upgrading risk patterns should be evaluated in low risk PCA patients before treatment. PMID- 30298711 TI - Intraprostatic Injections for LUTS/BPH treatment. AB - BACKROUND: Endoscopic surgical treatment represents the gold standard in patients with lower urinary tract symptoms (LUTS) when medical treatment fails. In the past years there has been a growing interest in intra-prostatic injections which represent a minimally invasive alternative for those patients not suitable for surgery. Aim of our study is to systematically review all the available data on intra-prostatic injections for the treatment of LUTS patients with benign prostatic enlargement (BPE). EVIDENCE ACQUISITION: A systematic review of the literature using the Medline, Scopus and Web of Science databases for relevant articles published until June 2018 was performed using both the Medical Subjects Heading and free test protocols. The MeSH search was conducted by combining the following terms: "Intra-prostatic Injections", "Botulinum Toxin A" "Onabotulinum" "Ethanol" "Lower Urinary tract Symptoms" "Benign prostatic enlargement" Benign Prostatic Hyperplasia" "NX1207" "PRX302". Each article's title and abstract were reviewed for their appropriateness and their relevance with regards to the relationship to intra-prostatic injections. EVIDENCE SYNTHESIS: Intra-prostatic injections for the treatment of LUTS/BPE patients may be performed using different products as: ethanol, onabotulinum toxin A, NX1207 and PRX 302. Ethanol, the first agent for intraprostatic use, showed promising results in prospective trials, however, the rare but serious adverse events associated with extraprostatic diffusion of ethanol stopped its use. Many studies on onabotulinum toxin A (BotoxR) have been performed, however, two large randomized clinical trials showed no differences in terms of symptoms improvements and flow improvements when compared to placebo. Two new promising drugs NX 1207 and PRX 302 have been developped in the past years. NX 1207 showed lack of efficacy in the two large European phase III RCT. PRX 302 showed promising results in phase I and II studies, however, definitive results from a large phase III randomized controlled trial (RCT) are awaited before drawing any definitive conclusions. CONCLUSIONS: Intraprostatic injections are still to be considered investigational for the minimally invasive management of LUTS/BPE patients. Emerging data suggest a possible role of new agents in the near future when definitive data of ongoing RCTs will be available.

AB - Crystal engineering of CH3NH3PbI3- xCl x perovskite films through modification by decoration with p-type semiconductor materials was proposed as an efficient method for obtaining good-quality crystalline films. A simple method is demonstrated to improve the quality of perovskite films by adding nickel oxide (NiO x) nanoparticles into the precursor solution. The addition of NiO x brings about high-quality crystals and convenient photo-generated charge transport with reduced defect density owing to efficient control of the preferred nucleation and crystal growth. The sufficient contact between CH3NH3PbI3- xCl x-NiO x and the electron-transport layer can contribute to photo-generated carrier lifetime and transport through the optimized interface. Moreover, it is demonstrated that a strong chemical bonding interaction between MAPbI3- xCl x and NiO x could protect perovskite materials from oxygen and humidity corrosion, showing remarkable stability holding ~81% of the initial power conversion efficiency (PCE) after 50 days. The device with the best PCE of 19.34% is achieved because of the improved short-circuit current from 22.23 to 23.01 mA cm-2 and fill factor from 68.97 to 75.06%. The results certify that this p-type charge transport material decoration method for the optimization of perovskite films is an efficient way to optimize the performance. PMID- 30298714 TI - Facet-Inspired Core-Shell Gold Nanoislands on Metal Oxide Octadecahedral Heterostructures: High Sensing Performance toward Sulfide in Biotic Fluids. AB - The development of structurally modified metal oxide heteroarchitectures with higher energy facets exposed has been of extensive research interests because of their unique construction and synergy effect of multifunctioning characteristics. In this study, we reported for the first time the development of a distinct type of gold nanoislands (AuNIs) on metal oxides (i.e., Cu2O-CuO) octadecahedral (ODH) heterostructures through the galvanic exchange reaction, where Cu2O not only acts as a stabilizer but also functions as a reductant. The electrocatalytic performance of the resultant core-shell Cu2O-CuO@AuNI ODH-based electrochemical sensing platform has been evaluated in ultrasensitive detection of sulfide as early disease diagnostics and bacterial marker. Owing to the synergistic collaboration of enhanced surface active sites, exposed {110} crystallographic facets, mixed valances of copper that encourage redox reactions at electrode material/analyte interface, and the polarization effect provide by AuNIs decorated onto the Cu2O surface, Cu2O-CuO@AuNI ODH-modified electrode has demonstrated striking electrochemical sensing performance toward sulfide oxidation in terms of broad linear range, real detection limit down to 1 nM (S/N = 3), and incredible durability and reproducibility. In virtue of marvelous efficiency, the proposed electrochemical sensor based on Cu2O-CuO@AuNI ODH has been employed in in situ sensitive detection of a ubiquitous amount of sulfide engendered by sulfate-reducing bacteria and real-time tracking of sulfide efflux from live cells as early diagnostic strategies. PMID- 30298715 TI - Characterization of Mechanical Degradation in Perfluoropolyether Film for Its Application to Antifingerprint Coatings. AB - Enhancing the mechanical durability of antifingerprint films is critical for its industrial application on touch-screen devices to withstand friction damage from repeated rubbing in daily usage. Using reactive molecular dynamics simulations, we herein implement adhesion, mechanical, and deposition tests to investigate two durability-determining factors: intrachain and interchain strength, which affect the structural stability of the antifingerprint film (perfluoropolyether) on silica. From the intrachain perspective, it is found that the Si-C bond in the polymer chain is the weakest, and therefore prone to dissociation and potentially forming a C-O bond. This behavior is demonstrated consistently, regardless of the cross-linking density between polymer chains. For the interchain interaction, increasing the chain length enhances the mechanical properties of the film. Furthermore, the chain deposition test, mimicking the experimental coating process, demonstrates that placing shorter chains first to the surface of silica and then depositing longer chains is an ideal way to improve the interchain interaction in the film structure. The current study reveals a clear pathway to optimize the configuration of the polymer chain as well as its film structure to prolong the product life of the coated antifingerprint film. PMID- 30298716 TI - Carbon Excess C3N: A Potential Candidate as Li-Ion Battery Material. AB - Xu et al.'s recent experimental work ( Adv. Mater. 2017, 29, 1702007) suggested that C3N is a potential candidate as Li-ion battery with unusual electrochemical characteristics. However, the obvious capacity loss (from 787.3 to 383.3 mA h.g 1) occurs after several cycles, which restricts its high performance. To understand and further solve this issue, in the present study, we have studied the intercalation processes of Li ions into C3N via first-principle simulations. The results reveal that the Li-ion theoretical capacity in pure C3N is only 133.94 mA h.g-1, the value is obviously lower than experimental one. After examining the experimental results in detail, it is found that the chemical component of the as-generated C xN structure is actually C2.67N with N excess. In this case, the calculated theoretical capacity is 837.06 mA h.g-1, while part of Li ions are irreversibly trapped in C2.67N, resulting in the capacity loss. This phenomenon is consistent with the experimental results. Accordingly, we suggest that N excess C3N, but not pure C3N, is the proposed Li-ion battery material in Xu et al.'s experiment. To solve the capacity loss issue and maintain the excellent performance of C3N-based anode material, the C3N with slightly excess C (C3.33N), which has been successfully fabricated in the experiment, is considered in view of its relatively low chemical activity as compared with N excess C3N. Our results reveal that the C excess C3N is a potential Li-ion battery material, which exhibits the low open circle voltage (0.12 V), high reversible capacity (840.35 mA h.g-1), fast charging/discharging rate, and good electronic conductivity. PMID- 30298717 TI - Role of Bimolecular Exciton Kinetics in Controlling the Efficiency of Organic Light-Emitting Diodes. AB - Here, we have carried out a spectroscopic investigation on the operational organic light-emitting diodes (OLEDs) to determine the role of emission layer thickness on the optoelectronic performance of OLEDs based on a poly(9,9 dioctylfluorene- alt-benzothiadiazole) (F8BT) copolymer system. Our study shows that delayed fluorescence (DF) via triplet-triplet annihilation (TTA) contributes significantly to boost the OLED efficiency through its fractional contribution. Interestingly, we note that DF contribution varies as a function of the emissive layer thickness. From the time-resolved electroluminescence (TREL) and triplet absorption (under electrical excitation) studies, we have seen that the emissive layer thickness controls triplet exciton generation and decay processes. From TREL, we have also shown that singlet-triplet annihilation (STA) is the dominant fluorescence quenching mechanism in bulk of the emissive layer, whereas thinner devices have significant exciton quenching at the interface of the injection layer/F8BT. The strength of STA differs in thin versus thick samples, which has been correlated with the spectral & spatial overlap integral of singlet and triplet states. Hence, STA strength and triplet population density are critical parameters for an explanation of high efficiency in unusually thick F8BT OLEDs. PMID- 30298718 TI - Prolonged Drug-Releasing Fibers Attenuate Alzheimer's Disease-like Pathogenesis. AB - Delivering drugs and agents to the brain is a huge challenge, especially for chronic neurodegenerative disorders, such as Alzheimer's disease (AD). For this, prolonged and sustained release methods to increase brain uptake represent an impacting concept. The bioresorbable polymer poly-lactic acid (PLA) has high potential for medical implants; at the same time, glucagon-like peptide-1 (GLP-1) analogues have considerable neuroprotective attributes and represent a therapeutic strategy for AD. Here, a biodevice is produced by electrospinning PLA with a GLP-1 analogue (liraglutide, LG), coated with a thin layer of gelatin. The biodevice is subcutaneously implanted in a transgenic mouse model of AD and LG is released for 14 days in mice serum. After 4 weeks of implantation, crucial hallmarks of the AD are highly diminished: hippocampal senile amyloid beta plaque load and neuroinflammatory markers. Furthermore, neurogenesis is enhanced in the subventricular zone, an important neurogenic niche in the brain. The designed biodevice holds great promise for being an affordable candidate to act as a prolonged drug provider, promoting LG mission through increasing its lifetime, constituting a relevant approach for old and impaired brain. PMID- 30298719 TI - Tumor Targeting and Lipid Rafts Disrupting Hyaluronic Acid-Cyclodextrin-Based Nanoassembled Structure for Cancer Therapy. AB - CD44 receptor targeting and lipid rafts destroying nanoassembly (NA) was developed for breast cancer therapy. Methyl-beta-cyclodextrin (MbCD), as a cholesterol depletion moiety, was conjugated to hyaluronic acid-ceramide (HACE) structure via an ester linkage. HACE-MbCD NA with 198 nm hydrodynamic size, unimodal size distribution, and spherical shape was fabricated by self-assembly strategy. By filipin III staining, it was identified that HACE-MbCD NA extracted cholesterol from the cellular membrane of MDA-MB-231 (human breast adenocarcinoma) cells more efficiently rather than MbCD and HACE NA. Efficient lipid rafts disruption of HACE-MbCD NA compared to MbCD and HACE NA groups seems to lead to the increment in apoptosis and antiproliferation efficiencies in MDA MB-231 cells. Improvement in tumor targeting efficiency of HACE-MbCD NA compared to HACE NA in MDA-MB-231 tumor-bearing mice can be explained by the extraction process of cellular cholesterol by MbCD. Following intravenous injection in MDA MB-231 tumor-bearing mice, the most efficient suppression of tumor growth and highest apoptotic region were observed in HACE-MbCD NA group rather than MbCD group. All of these findings suggest that CD44 receptor-targetable HACE-MbCD NA retaining cholesterol depletion activity from cancer cells may be one of the remarkable nanosystems for breast cancer therapy. PMID- 30298720 TI - Fabrication of Ge:Ga Hyperdoped Materials and Devices Using CMOS-Compatible Ga and Ge Hydride Chemistries. AB - We report a versatile chemical vapor deposition (CVD) method to dope Ge films with Ga atoms in situ over a wide concentration range spanning from 3 * 1018 to 2.7 * 1020 cm-3. The method introduces a stable and volatile Ga hydride [D2GaN(CH3)2]2 that reacts readily with Ge4H10 to deliver Ga dopants controllably and systematically at complementary metal-oxide-semiconductor compatible ultralow temperatures of ~360 degrees C. Thick and monocrystalline layers (1.3 MUm) are produced on Si substrates at growth rates approaching 50 nm/min. The doped crystals are fully epitaxial and devoid of misfit defects and Ga precipitates as evidenced by Rutherford backscattering spectrometry, X-ray diffraction, and cross sectional transmission electron microscopy. The Ga contents measured by secondary ion mass spectrometry and the active carrier concentrations determined by spectroscopic ellipsometry (as well as Hall effect measurements in several cases) are in close agreement, indicating near full activation. Photoluminescence spectra show a strong emission peak at 0.79 eV corresponding to the direct gap E0 transition, evidence of the indirect transition, and additional structures characteristic of p-type Ge. Electroluminescence and I- V curves measured from p(Ga)-i-n photodiodes are found to be at par with those from boron-based reference devices. These results are promising and demonstrate that a single source CVD approach allows independent control of Ga doping level and junction depth, producing flat dopant profiles, high activation ratios, uniform distributions, and sharp interfaces. This method potentially represents a viable alternative to state-of-the-art boron-based p-type doping and activation of Ge like materials. PMID- 30298721 TI - Antibacterial Micelles with Vancomycin-Mediated Targeting and pH/Lipase-Triggered Release of Antibiotics. AB - Antibiotic delivery systems play an important role in increasing the efficacy while reducing the off-target toxicity and antibiotic resistance. Though bacterial infections share pathophysiological pathways similar to tumor tissues, few delivery systems have achieved bacterial targeting and on-demand release of antibiotics. In the current study, amphiphilic poly(ethylene glycol)-poly(epsilon caprolactone) (PECL) copolymers are conjugated with vancomycin (VAN) as targeting ligands via pH-cleavable hydrazone bonds to obtain micelle carriers (Van-hyd PECL). Subsequently, ciprofloxacin (CIP) is encapsulated to obtain Van-hyd PECL/Cip micelles with an average size of 77 nm and a CIP loading amount of 4.5%. The poly(ethylene glycol) shells and the extension of VAN moieties on the micelle surface enhance the blood circulation and selective recognition of bacteria. The deshielding of VAN shells under acidic conditions disrupts the hydrophobic/hydrophilic balance leading to an increase in micelle sizes, which facilitates the degradation of poly(epsilon-caprolactone) by lipase overexpressed in the infection site and the release of encapsulated CIP for bacterial destruction. The micelle treatment has improved the survival of Pseudomonas aeruginosa-infected mice and reduced the bacterial burdens and alveolar injuries in lungs, compared with free drugs and micelles without inoculation of VAN moieties. Three doses of Van-hyd-PECL/Cip micelles further extend the animal survival, decrease the bacterial colonization in lungs, and almost restore the normal alveolar microstructure. In this regard, this study has demonstrated a strategy to enhance the bacterial targeting of micelles via an antibiotic (VAN) and to sequentially trigger the release of antibiotics (VAN and CIP) at the infection site.

AB - On account of the low-temperature solution fabrication, the much high defect density at the interfaces and grain boundaries of halide perovskite films is recognized as one of the big obstacles toward high-efficiency solar cells. Here, the time-resolved photoluminescence (TRPL) with incident light exciting from the upper surface and bottom of halide perovskite films, respectively, showed very different results, verifying the much more surface trap states in the film. To eliminate the defects and enhance the photovoltaic properties of perovskite solar cells (PSCs), we designed a facile and effective method to repair the defects of the perovskite film using formamidinium iodine (FAI) solution. The dissociative FA+ and I- ions could compensate for the loss of volatile organic cations and also fill the I- vacancies of halide perovskites. After repairing defects with proper concentration of FAI solution, the TRPL curves obtained by light exciting from the different sides of the perovskite film nearly overlap together, indicating the reduction of surface traps. As a result, both the total carrier lifetime and charge extractions were improved by removing the nonradiative channels (surface traps), which universally enhanced the power conversion efficiency and stability of the planar heterojunction structural PSCs.

AB - Lithium-sulfur (Li-S) batteries offer higher energy densities than most reported lithium-ion batteries. However, our understanding of Li-S battery is still largely unknown at the level of the nanoscale. The structural properties of Li-S materials were investigated via molecular dynamics (MD) simulations using the ReaxFF force field. Several Li-S nanoparticles with different Li/S composition ratios (2:1 and 2:8) and various structures are studied. Our MD simulations show that among the four structures we constructed for Li2S8 nanoparticles, the core shell structure is the most thermodynamically stable one during the charging (delithiation) process. In contrast to bulk crystal Li2S, we find the presence of mixed lithium sulfide and polysulfide species are common features for these Li-S (Li2S, Li2S8) nanoparticles. The complex distribution of these sulfide and polysulfide speciation are dictated by both stoichiometry and local atomic structures in the nanoparticle. These findings will provide insight into further development of functionalized lithium-sulfur cathodes. PMID- 30298724 TI - Scalable, High-Performance Printed InO x Transistors Enabled by Ultraviolet Annealed Printed High- k AlO x Gate Dielectrics. AB - Inorganic transparent metal oxides represent one of the highest performing material systems for thin-film flexible electronics. Integrating these materials with low-temperature processing and printing technologies could fuel the next generation of ubiquitous transparent devices. In this work, we investigate the integration of UV-annealing with inkjet printing, demonstrating how UV-annealing of high- k AlO x dielectrics facilitates the fabrication of high-performance InO x transistors at low processing temperatures and improves bias-stress stability of devices with all-printed dielectrics, semiconductors, and source/drain electrodes. First, the influence of UV-annealing on printed metal-insulator-metal capacitors is explored, illustrating the effects of UV-annealing on the electrical, chemical, and morphological properties of the printed gate dielectrics. Utilizing these dielectrics, printed InO x transistors were fabricated which achieved exceptional performance at low process temperatures (<250 degrees C), with linear mobility MUlin ~ 12 +/- 1.6 cm2/V s, subthreshold slope <150 mV/dec, Ion/ Ioff > 107, and minimal hysteresis (<50 mV). Importantly, detailed characterization of these UV-annealed printed devices reveals enhanced operational stability, with reduced threshold voltage ( Vt) shifts and more stable on-current. This work highlights a unique, synergistic interaction between low-temperature-processed high- k dielectrics and printed metal oxide semiconductors. PMID- 30298725 TI - Identification of Myricetin as an Ebola Virus VP35-Double-Stranded RNA Interaction Inhibitor through a Novel Fluorescence-Based Assay. AB - Ebola virus (EBOV) is a filovirus that causes a severe and rapidly progressing hemorrhagic syndrome; a recent epidemic illustrated the urgent need for novel therapeutic agents because no drugs have been approved for treatment of Ebola virus. A key contribution to the high lethality observed during EBOV outbreaks comes from viral evasion of the host antiviral innate immune response in which viral protein VP35 plays a crucial role, blocking interferon type I production, first by masking the viral double-stranded RNA (dsRNA) and preventing its detection by the pattern recognition receptor RIG-I. Aiming to identify inhibitors of the interaction of VP35 with the viral dsRNA, counteracting the VP35 viral innate immune evasion, we established a new methodology for high-yield recombinant VP35 (rVP35) expression and purification and a novel and robust fluorescence-based rVP35-RNA interaction assay ( Z' factor of 0.69). Taking advantage of such newly established methods, we screened a small library of Sardinian natural extracts, identifying Limonium morisianum as the most potent inhibitor extract. A bioguided fractionation led to the identification of myricetin as the component that can inhibit rVP35-dsRNA interaction with an IC50 value of 2.7 MUM. Molecular docking studies showed that myricetin interacts with the highly conserved region of the VP35 RNA binding domain, laying the basis for further structural optimization of potent inhibitors of VP35-dsRNA interaction. PMID- 30298726 TI - Novel Strategy for the Investigation on Chirality Selection of Single-Walled Carbon Nanotubes with DNA by Electrochemical Characterization. AB - There is a correlation between specific bases of DNA molecules and the chirality of single-walled carbon nanotubes (SWNTs), which contributes the recognition ability of DNA toward partner species of chiral SWNTs. A novel strategy of electrochemical characterization is reported here for the investigation on chirality selection of (7,6) and (6,5) SWNTs with various DNA sequences, and it is found that both DNA strand length and sequence composition significantly affected the interaction of chiral SWNTs with DNA. Then (7,6) and (6,5) SWNTs were distinguished from each other with DNA sequences chosen by electrochemical methods, which demonstrated an effective and excellent feasibility for the strategy and presented a new insight into DNA-SWNT applications. This strategy can also be applied to more chiral SWNTs and DNA sequence recognition and may serve as a prescreening method for the recognition and separation of single chirality SWNTs, which would be a new contribution to the further development of DNA-SWNT hybrids. PMID- 30298727 TI - Photoelectrochemical-Chemical-Chemical Redox Cycling for Advanced Signal Amplification: Proof-of-Concept Toward Ultrasensitive Photoelectrochemical Bioanalysis. AB - Signal amplification is essential for ultrasensitive photoelectrochemical (PEC) bioanalysis. Exploration of the facile and efficient route for multiple signal amplification is highly appealing. Herein, we present the concept of photoelectrochemical-chemical-chemical (PECCC) redox cycling as an advanced signal amplification route and a proof-of-concept toward ultrasensitive PEC bioanalysis. The system operated upon the bridging between the enzymatic generation of signaling species ascorbic acid (AA) from a sandwich immunoassay and the PECCC redox cycling among the ferrocenecarboxylic acid as redox mediator, the AA, and the tris(2-carboxyethyl)phosphine as reducing agent at the Bi2S3/Bi2WO6 photoelectrode. Exemplified by myoglobin (Myo) as target, the proposed system achieved efficient regeneration of AA and thus signal amplification toward the ultrasensitive split-type PEC immunoassay. This work first exploited the PECCC redox cycling, and we believe it will attract more interest in the research of PEC bioassays on the basis of advanced redox cycling. PMID- 30298728 TI - Application of Experimental Polystyrene Partition Constants and Diffusion Coefficients to Predict the Sorption of Neutral Organic Chemicals to Multiwell Plates in in Vivo and in Vitro Bioassays. AB - Sorption to the polystyrene (PS) of multiwell plates can affect the exposure to organic chemicals over time in in vitro and in vivo bioassays. Experimentally determined diffusion coefficients in PS ( DPS) were in a narrow range of 1.25 to 8.0 . 10-16 m2 s-1 and PS-water partition constants ( KPS/w) ranged from 0.04 to 5.10 log-units for 22 neutral organic chemicals. A kinetic model, which explicitly accounts for diffusion in the plastic, was applied to predict the depletion of neutral organic chemicals from different bioassay media by sorption to various multiwell plate formats. For chemicals with log Kow > 3, the medium concentrations decreased rapidly and considerably in the fish embryo toxicity assay but medium concentrations remained relatively constant in the cell-based bioassays with medium containing 10% fetal bovine serum (FBS), emphasizing the ability of the protein- and lipid-rich medium to compensate for losses by multiwell plate sorption. The PS sorption data may serve not only for exposure assessment in bioassays but also to model the contaminant uptake by and release from plastic packaging material and the chemical transport by PS particles in the environment. PMID- 30298729 TI - Deposition Mapping of Polycyclic Aromatic Compounds in the Oil Sands Region of Alberta, Canada and Linkages to Ecosystem Impacts. AB - This study produced gridded deposition estimates of polycyclic aromatic compounds (PACs), including 17 polycyclic aromatic hydrocarbons (PAHs), 21 alkylated PAHs (alk-PAHs), and 5 dibenzothiophenes (DBTs), over the oil sands region of Alberta, Canada and surrounding communities. Gridded annual total deposition of PACs in 2011 ranged from 55 to 175 000 MUg m-2 yr-1 and the mean and median fluxes were 1700 and 760 MUg m-2 yr-1, respectively. The domain-wide mean dry and wet deposition were 600 and 1100 MUg m-2 yr-1. PAHs, alk-PAHs and DBTs contributed 19%, 74%, and 7% to the total dry deposition, and 42%, 49%, and 9% to the total wet deposition. Dominant chemical species contributing to total deposition were naphthalene, retene and phenanthrene for PAHs and C2 benz[a]anthracene/triphenylene/chrysene, C2-fluoranthene/pyrene and C2-fluorene for alk-PAHs. The highest PAC deposition was found over the surface mineable area, which received 9 times the deposition flux of outlying areas. Additional deposition hotspots were also observed south of the surface mineable area notably over in situ bitumen production sites. The deposition of alk-PAHs impacted a more extensive area than that of PAHs or DBTs. This result suggests that atmospheric deposition is a key process in wildlife exposure to PACs across the region. PMID- 30298730 TI - Bioaccumulation, Biotransformation, and Synergistic Effects of Binary Fungicide Mixtures in Hyalella azteca and Gammarus pulex: How Different/Similar are the Two Species? AB - Aquatic organisms are consistently exposed to a mixture of micropollutants that can bioaccumulate, undergo biotransformation, and may exert mixture effects. However, little is known on the underlying mechanisms and species-specificity. Herein we investigated bioaccumulation, biotransformation and synergistic effects of azole (i.e., prochloraz) and strobilurin (i.e., azoxystrobin) fungicides in the two aquatic invertebrate species, Hyalella azteca and Gammarus pulex. Bioaccumulation of azoxystrobin was similar, whereas bioaccumulation of prochloraz was slightly different in the two species but was still significantly below the REACH criteria for bioaccumulative substances. Similar biotransformation patterns were observed in both species, and only a few unique biotransformation reactions were detected in H. azteca such as malonyl-glucose and taurine conjugation. Toxicokinetic modeling additionally indicated that biotransformation is a more important elimination pathway in H. azteca. In mixtures, no-observed-adverse-effect levels of prochloraz decreased the LC50s of azoxystrobin in both species which correlated well with increased internal azoxystrobin concentrations. This synergistic effect is partly due to the inhibition of cytochrome P450 monooxygenases by prochloraz which subsequently triggered the reduced biotransformation of azoxystrobin (lower by five folds in H. azteca). The largely similar responses in both species suggest that the easier to-cultivate H. azteca is a promising representative of invertebrates for toxicity testing. PMID- 30298731 TI - Accuracy, Repeatability, and Limitations for Determination of Chemical Activities from Vapor Pressure Osmometry. AB - Vapor pressure osmometry presents a convenient method to measure chemical activity. The work presented here was carried out to provide confidence in using this technique for a VPO model that does not utilize the "hanging-drop" method. While validation studies are available for certain models of vapor pressure osmometers, none were located for the UIC Jupiter 833 osmometer. This study addresses that need by providing a comparison between original experimental data on sodium chloride, calcium chloride, and sodium sulfate solutions to values calculated using the Pitzer equations. A comparison is also made for experimental data on sucrose with a literature correlation. This study briefly reviews the assumptions going into the equation used to relate the osmometer signal to the diluent activity in order to identify potential sources of the error and the noise in the data. The experimental data shows that the UIC 833 osmometer yields diluent activity values accurate to an average of 0.02%, allowing calculation of osmotic coefficients and solute activity coefficients. Further studies need to be conducted on the accuracy at concentrations above 1.4 m. Qualitatively, however, comparison suggests the UIC Jupiter 833 osmometer yields more scatter in the experimental data than the Knauer instruments. Using more uniform mesh caps on the thermistors could possibly reduce that scatter. Finally, we show that replacing the glass thermistors with in-house made thermistors with Teflon incorporated in the structure give reproducible results and that certain modifications to the design are possible without losing accuracy in the measurements. PMID- 30298732 TI - Boosting Modulation of Oxide Semiconductors via Voltage-Based Ambi-Ionic Migration. AB - In recent years, high-performance amorphous oxide semiconductor thin-film transistor (AOS TFT) technology is required to meet the increasing demand for novel displays, such as rollable, transparent, or augmented reality head-up displays. It has been demonstrated that voltage-based modulation techniques for AOS-based active layers can achieve high-performance AOS TFTs. The voltage-based modulation technique allows specific ions to migrate into the active layer depending on the polarity of the applied voltage, thus easily modulating the active layer. Additionally, potassium superoxide (KO2) solution is employed in AOS TFTs as a source of potassium (K+) and highly reactive superoxide radical (O2*-) ions. The K+ and O2*- ions in the KO2 solution are controlled by an applied voltage bias and rapidly migrate into the active layer, directly changing its chemical composition and electrical properties. AOS TFTs that use this technique exhibit better electrical performance than conventional AOS TFTs: the field-effect mobility improved from 10.05 to 15.31 cm2/V.s; the subthreshold swing decreased from 0.44 to 0.33 V/dec; the Ion/off ratio increased from 1.24 * 107 to 3.17 * 108; and the threshold voltage shift decreased from 5.2 to 3.4 V under a positive bias stress test conducted over 10 000 s. Ultimately, this approach to modulating the internal ion distribution in oxide semiconductors could provide opportunities for various AOS devices to attain desirable electrical characteristics.

AB - A new strategy for the synthesis of bis-indoletriazoles was developed using a sequential one-pot four-step procedure via I2 and H2SO4-SiO2 catalyzed Friedel Crafts reactions of indole with aldehyde followed by N-alkylation with propargyl bromide, azidation, and copper(I)-catalyzed azide alkyne cycloaddition (CuAAC). The reaction proceeded smoothly at room temperature in a short time, and a series of bis-indoletriazoles were obtained in good to excellent yields proving the generality of this one-pot methodology. PMID- 30298734 TI - Proteogenomics of Adenosine-to-Inosine RNA Editing in the Fruit Fly. AB - Adenosine-to-inosine RNA editing is one of the most common types of RNA editing, a posttranscriptional modification made by special enzymes. We present a proteomic study on this phenomenon for Drosophila melanogaster. Three proteome data sets were used in the study: two taken from public repository and the third one obtained here. A customized protein sequence database was generated using results of genome-wide adenosine-to-inosine RNA studies and applied for identifying the edited proteins. The total number of 68 edited peptides belonging to 59 proteins was identified in all data sets. Eight of them being shared between the whole insect, head, and brain proteomes. Seven edited sites belonging to synaptic vesicle and membrane trafficking proteins were selected for validation by orthogonal analysis by Multiple Reaction Monitoring. Five editing events in cpx, Syx1A, Cadps, CG4587, and EndoA were validated in fruit fly brain tissue at the proteome level using isotopically labeled standards. Ratios of unedited-to-edited proteoforms varied from 35:1 ( Syx1A) to 1:2 ( EndoA). Lys-137 to Glu editing of endophilin A may have functional consequences for its interaction to membrane. The work demonstrates the feasibility to identify the RNA editing event at the proteome level using shotgun proteomics and customized edited protein database.

AB - A Pd/norbornene-catalyzed direct meta-alkylation of nosyl-protected phenylalanine derivatives with alkyl iodides is reported in moderate to good yields. The use of diisopropyl bicyclo[2.2.1]hept-5-ene-2,3-dicarboxylate is identified as a more suitable transient mediator. A simple pyridine ligand is also essential for this reaction to proceed. No racemization was observed in this meta-methylation reaction. PMID- 30298736 TI - Antileishmanial Carbasugars from Geosmithia langdonii. AB - Two new carbasugar-type metabolites, (1 S,2 R,3 R,4 R,5 R)-2,3,4-trihydroxy-5 methylcyclohexyl-2',5'-dihydroxybenzoate (1) and (1 S,2 S,3 S,4 R,5 R)-4-[(2',5' dihydroxybenzyl)oxy]-5-methylcyclohexane-1,2,3-triol (2), were isolated from the filamentous fungus Geosmithia langdonii isolated from cotton textiles from Assiut, Egypt. The structures of 1 and 2 were elucidated based on comprehensive 1D and 2D NMR and MS data. Compounds 1 and 2 showed antileishmanial activity against Leishmania donovani with IC50 values of 100 and 57 MUM, respectively. The (1 S,2 R,3 R,4 R,5 R) absolute configuration of carbasugar 1 was assigned via 2D NMR and experimental and calculated electronic circular dichroism (ECD) data. Similarly, the tentative structure of compound 2 was shown to possess a (1 S,2 S,3 S,4 R,5 R) absolute configuration via comparing its experimental ECD data and the specific rotation with 1 as well as examining the energy-minimized 3D computational models of compounds 1 and 2. PMID- 30298737 TI - Nanofilamentous Virus-Based Dynamic Hydrogels with Tunable Internal Structures, Injectability, Self-Healing, and Sugar Responsiveness at Physiological pH. AB - With expanding applications of hydrogels in diverse fields ranging from biomaterials to sensors, actuators, and soft robotics, there is an urgent need to endow one single gel with multiple physicochemical properties, such as stimuli responsiveness, injectability, self-healing, and tunable internal structures. However, it is challenging to simultaneously incorporate these highly sought after properties into one single gel. Herein, a conceptual hydrogel system with all of these properties is presented via combining bioconjugate chemistry, filamentous viruses, and dynamic covalent bonds. Nanofilamentous bioconjugates with diol affinity were prepared by coupling a tailor-synthesized low-p Ka phenylboronic acid (PBA) derivative to a well-defined green nanofiber the M13 virus with a high aspect ratio (PBA-M13). Dynamic hydrogels with tunable mechanical strength were prepared by using multiple diol-containing agents such as poly(vinyl alcohol) to cross-link such PBA-M13 via the classic boronic-diol dynamic bonds. The as-prepared hydrogels exhibit excellent injectability and self healing behaviors as well as easy chemical accessibility of the PBA moieties on the virus backbone inside the gel matrix. Ordered internal structures were imparted into virus-based hydrogels by simple shear-induced alignment of the virus nanofibers. Furthermore, unique hydrogels with chiral internal structures were fabricated through in situ gelation induced by diffusion of diol-containing molecules to fix the chiral liquid crystal phase of the PBA-M13 virus. Sugar responsiveness of this gel leads to a glucose-regulated release behavior of payloads such as insulin. All of these properties have been implemented at physiological pH, which will facilitate future applications of these hydrogels as biomaterials.

AB - A simple C-H/N-H bond functionalization of N-aryl amidines with cyclic 2-diazo 1,3-diketones for the synthesis of 1-aminoisoquinolines has been accomplished by employing [Cp*RhCl2]2/CsOPiv as the catalyst system. This methodology proceeds by a cascade C-H activation/intramolecular cyclization under mild reaction conditions, features a broad substrate scope, and involves the formation of two new sigma bonds (C-C and C-N) in a single operation for the construction of novel 1-aminoisoquinoline skeletons in good to excellent yields.

AB - Eight new matrine-type alkaloids, flavesines G-J (1-4), alopecurine B (5), 7,11 dehydro-oxymatrine (6), 10-oxy-5,6-dehydromatrine (7), and 10-oxysophoridine (8), along with nine known analogues (9-17) were isolated from the roots of Sophora flavescens. Compounds 1-3 are the first natural matrine-type alkaloids with an open-loop ring D, while compound 4 represents an unprecedented dimerization pattern constructed from matrine and piperidine, and 5 is the first example of a matrine-type alkaloid with cleavage of the C-5-C-6 bond. The new structures were elucidated by means of spectroscopic data analysis (including NMR, MS, IR, and UV), and the absolute configurations were determined using single-crystal X-ray diffraction and ECD data. The isolated alkaloids were evaluated for their antiviral activity against hepatitis B virus, and compounds 1, 4, 5, 10, and 14 exhibited comparable antiviral potencies to matrine. PMID- 30298738 TI - Risks Related to High-Dosage Recombinant Antimicrobial Peptide Microcin J25 in Mice Model: Intestinal Microbiota, Intestinal Barrier Function, and Immune Regulation. AB - Antimicrobial peptide (AMP) can be a promising alternative in various domains. However, further risk information is required. In this study, mice were orally administrated different dosages of recombinant AMP microcin J25 (4.55, 9.1, and 18.2 mg/kg; MccJ25) for 1 week, and the toxicity risk impacts were examined. We evidenced that middle-dosage administration mice had a lower inflammation, better body weight, and ameliorated mucosal morphology, accompanied by reduced intestinal permeability and tighter intestinal barrier. Fecal microbiota composition analysis in middle- or low-dosage mice revealed the Bifidobacterium count was increased and the coliform bacteria count was decreased, and increased in short-chain fatty acid levels. Unexpectedly, there was a risk that high-dosage mice increased intestinal permeability and imbalance of intestinal bacteria. Taken together, these data indicated a safe threshold for usage of MccJ25 in clinical practice. Such studies can effectively enhance the safety of various aspects such as food preservative and drug. PMID- 30298741 TI - Adsorption Thicknesses of Confined Pure and Mixing Fluids in Nanopores. AB - In this paper, adsorption thicknesses of confined pure and mixing fluids in nanopores are quantitatively determined and their influential factors are specifically evaluated. First, a new analytical formulation is developed thermodynamically to calculate the adsorption thicknesses. Second, a new generalized equation of state (EOS), which considers the confinement effect induced phenomena, is developed analytically for calculating the thermodynamic confined fluid phase behavior. Third, the modified model based on the generalized EOS and coupled with the parachor model is applied to calculate the vapor-liquid equilibrium (VLE) and fluid adsorptions for the pure CO2, alkanes of C1-C10, and two mixtures of CO2-C10H22 and CH4-C10H22 in nanopores. Finally, the following five important factors are studied to evaluate their effects on the adsorption thickness: temperature, pressure, pore radius, wall-effect distance, and feed gas to-liquid ratio (FGLR). The proposed modified EOS is found to be accurate for the VLE and adsorption isotherm calculations. The adsorption thicknesses of confined pure or mixing alkanes are increased with the increasing carbon number but decreased with the temperature increase. For the alkanes of C1-C10, the degree of temperature effect is strengthened with the carbon number increase. Moreover, the adsorption thicknesses are significantly decreased with the pore radius increase until rp = 50 nm, after which they have slight changes or are even constant at any pore radii. On the other hand, the wall-effect distance (deltap) increase causes the adsorption thickness to be linearly increased at deltap/ rp >= 0.02. In addition, the effects of the FGLR and pressure on the adsorption thicknesses at the nanoscale are found to be negligible. PMID- 30298742 TI - Absorption, Metabolism, and Pharmacokinetics Profiles of Norathyriol, an Aglycone of Mangiferin, in Rats by HPLC-MS/MS. AB - Norathyriol, an aglycone of mangiferin, is a bioactive tetrahydroxyxanthone present in mangosteen and many medicinal plants. However, the biological fate of norathyriol in vivo remains unclear. In this study, the absorption and metabolism of norathyriol in rats were evaluated through HPLC-MS/MS. Results showed that norathyriol was well absorbed, as indicated by its absolute bioavailability of 30.4%. Besides, a total of 21 metabolites of norathyriol were identified in rats, including methylated, glucuronidated, sulfated and glycosylated conjugates, which suggested norathyriol underwent extensive phase II metabolism. Among those metabolites, 15 metabolites were also identified in hepatocytes incubated with norathyriol, indicating the presence of hepatic metabolism. Furthermore, glucuronide and sulfate conjugates, rather than their parent compound, were found to be the main forms existing in vivo after administration of norathyriol, as implicated by the great increase of exposure of norathyriol determined after hydrolysis with beta-glucuronidase and sulfatase. The information obtained from this study contributes to better understanding of the pharmacological mechanism of norathyriol. PMID- 30298743 TI - Pattern-based formulation: clinical case 5.

PMID- 30298744 TI - Engaging older adults in discharge planning: case studies illuminating approaches adopted by family members that promote relational autonomy. AB - BACKGROUND: Discharge decisions have significant implications for older adults and their involved family members. Evidence of older adult and family members' engagement in discharge decision-making, however, varies widely. Some recent work shows assumed associations between ageing, diminished participation in healthcare decision-making and increased reliance on family members. Other research suggests that family members adopt strategies to promote older adults' participation in decision-making. Relational autonomy theory suggests that individuals have differing levels of autonomy and that individuals' agency can be supported (or marginalized) by others. PURPOSE: Using three case studies, we examine traditional and relational conceptions of autonomy and explore how relational approaches could inform healthcare practice. METHODS: Taking a critical feminist bioethics perspective, we present a secondary analysis of three microethnographic case studies focused on discharge planning with older adults in one Canadian inpatient rehabilitation setting. The data consist of observations of discharge planning family conferences and semi-structured interviews with older adults and family members. RESULTS: Tensions between older adults' wishes to return home and their diminished participation in discharge decisions, and family members' assumption of a primary role in discharge decision-making and their wish for the older adult to move to a supported setting were apparent. To reconcile these tensions, the older adults' family members in these cases employed strategies to promote older adults' participation in decision-making that were consistent with relational autonomy theory. CONCLUSION AND IMPLICATIONS FOR PRACTICE: The analysis suggests that older adults' participation in discharge decision-making processes could be better promoted through relational approaches. Implications for rehabilitation * Adopting an approach guided by relational autonomy might better enable patients to participate in decision-making than would an approach guided by traditional conceptions of autonomy. * Rehabilitation professionals could seek assistance from family members and guide them toward collaborative partnerships. * A range of strategies may be employed to customize relational approaches to enhance autonomy: * having several different conversations with patients to enable multiple chances to contribute knowledge and views; * involving family members or taking the time to explain information several different times and in diverse manners; * showing patients videos or photos of discharge locations; * exploring a breadth of potential discharge options; * accompanying patients to visit different options in person; and * getting patients in touch with individuals who have made similar choices. * It is recognized that taking a relational approach might be time-consuming and that practice contexts may not be conducive to such practice. PMID- 30298745 TI - Working life trajectories with hearing impairment. AB - PURPOSE: The aim was to identify and explore factors, which facilitate or hinder work participation for people with hearing impairment. MATERIALS AND METHODS: In depth interviews with 21 hearing impaired individuals of 32-67 years of age with a present or recent vocational affiliation were conducted. The analysis was conducted using a grounded theory approach. RESULTS: The analysis resulted in a conceptual framework of working life trajectories evolving through three phases of acknowledgement of hearing loss impact: the pre-acknowledgement, acknowledgement, and post-acknowledgement phase. The phases were influenced by the qualities of three contexts: the personal, the workplace, and the service provider. The qualities of the contexts, together with the amount of time spent in a pre-acknowledgement phase, formed the trajectories towards continuation of work participation or towards a disconnection. Accumulated risk factors constituted increased likelihood of disconnecting trajectories, while accumulated facilitating factors supported sustainable trajectories. CONCLUSIONS: The results revealed a need for extended support at the workplaces, which includes the manager, colleagues, and professionals in the aim of preventing exhaustion and facilitate work participation among employees with hearing impairments. Joint action in facilitating communicative participation would share the responsibility for accommodation measures and broaden the room for manoeuver at the workplace. Implications for rehabilitation Fatigue prevention in employees with hearing loss needs to be addressed in occupational rehabilitation. Knowledge transfer on hearing loss implications needs to be included in aural rehabilitation. Occupational rehabilitation professionals and professionals targeting hearing impairments should enter into systematic, multidisciplinary follow-up at the worksite.

AB - Decellularized extracellular matrices have been clinically used for tendon regeneration. However, only a few systematic studies have compared tendon stem/progenitor cells to mesenchymal stromal cells on the tendon-derived decellularized matrix. In the present study, we prepared extracellular matrix derived from porcine tendons and seeded with tendon stem/progenitor cells, embryonic stem cell-derived mesenchymal stromal cells or without stem cells. Then we implanted the mixture (composed of stem cells and scaffold) into the defect of a rat Achilles tendon. Next, 4 weeks post-surgery the regenerated tendon tissue was collected. Histological staining, immunohistochemistry, determination of collagen content, transmission electron microscopy, and biomechanical testing were performed to evaluate the tendon structure and biomechanical properties. Our study collectively demonstrated that decellularized extracellular matrix derived from porcine tendons significantly promoted the regeneration of injured tendons when combined with tendon stem/progenitor cells or embryonic stem cell mesenchymal stromal cells. Compared to embryonic stem cell-mesenchymal stromal cells, tendon stem/progenitor cells combined with decellularized matrix showed more improvement in the structural and biomechanical properties of regenerated tendons in vivo. These findings suggest a promising strategy for functional tendon tissue regeneration and further studies are warranted to develop a functional tendon tissue regeneration utilizing tendon stem/progenitor cells integrated with a tendon-derived decellularized matrix. PMID- 30298747 TI - Naive B-cell output in HIV-infected and HIV-uninfected children. AB - BACKGROUND: In this study, we aimed to quantify KREC (kappa-deleting recombination excision circles) levels and naive B-cell output in healthy HIV uninfected children, compared with HIV-infected South African children, before and after starting ART (anti-retroviral therapy). SETTING: Samples were acquired from a Child Wellness Clinic (n=288 HIV-uninfected South African children, 2 weeks - 12 years) and the Children with HIV and Early Antiretroviral Therapy (CHER) trial (n=153 HIV-infected South African children, 7 weeks - 8 years). METHODS: Naive B-cell output was estimated using a mathematical model combining KREC levels to reflect B-cell emigration into the circulation, flow cytometry measures of naive un-switched B-cells to quantify total body naive B-cells, and their rates of proliferation using the intracellular marker Ki67. RESULTS: Naive B-cell output increases from birth to 1 year, followed by a decline and plateau into late childhood. HIV-infected children on or off ART had higher naive B-cell outputs than their uninfected counterparts (p=0.01 and p=0.04). CONCLUSIONS: This is the first study to present reference ranges for measurements of KRECs and naive B-cell output in healthy and HIV-infected children. Comparison between HIV uninfected healthy children and HIV-infected children suggest that HIV may increase naive B-cell output. Further work is required to fully understand the mechanisms involved and clinical value of measuring naive B-cell output in children. .

AB - Korean red ginseng (KRG) is a traditional herbal medicine used to prevent several geriatric diseases due to its therapeutic effects on metabolic disorder, including type 2 diabetes and fatty liver disease. In this study, we investigated the effects of KRG on the progression of nonalcoholic steatohepatitis (NASH) in mice. NASH was induced by feeding a methionine- and choline-deficient high-fat or high-fat/high-sucrose diet for 6 or 13 weeks, respectively. Each diet group was also orally administered saline (group G0) or KRG extract (100, 200, or 400 mg/kg/day; groups G1, G2, and G4, respectively). KRG showed anti-inflammatory and antifibrogenic effects in the diet-induced NASH models. Furthermore, the expression levels of lipid metabolism-related genes were markedly decreased with KRG treatment in both diet-induced NASH groups. We next confirmed the expression levels of FABP4 in the liver and its ability to regulate inflammation and/or oxidative stress. We observed decreased levels of FABP4 mRNA and protein in the KRG-treated groups indicating that KRG affects the pathogenesis of NASH-related inflammatory responses by modulating FABP4 expression. Results of in vitro experiments showed similar patterns in cells treated with KRG, indicating that KRG treatment regulates the expression of FABP4 and subsequently reduces NASH related inflammation. Our findings suggest a novel role of KRG in NASH-related inflammatory responses via modulation of FABP4 expression in the liver. KRG may be a safe alternative therapy to prevent NASH progression. PMID- 30298749 TI - The Most Commonly Treated Acupuncture Indications in the United States: A Cross Sectional Study. AB - Acupuncture has been a popular alternative medicine in the United States for several decades. Its therapeutic effects on pain have been validated by both basic and clinical researches, and it is currently emerging as a unique non pharmaceutical choice for pain against opioid crisis. However, the full spectrum of acupuncture indications remains unexplored. In this study, we conducted a cross-sectional survey among 419 acupuncturists nation-wide to investigate the top 10 and top 99 acupuncture indications in private clinics in the United States. We found the top 10 indications to be: lower back pain, depression, anxiety, headache, arthritis, allergies, general pain, female infertility, insomnia, neck pain and frozen shoulder. Among the top 99 indications, pain represents the largest category; and mental health management, especially for mood disorders, is in greatest demand. The following popular groups are: immune system dysfunctions, gastrointestinal diseases, gynecology and neurology. In addition, specialty index, commonality index, and the potential to become medical specialties were estimated for each indication. Demographic analysis suggests that China trained acupuncturists tend to have broader indication spectrums, but the top conditions treated are primarily decided by local needs. Also, gender, resident states, age and clinical experience all affect indication distributions. Our data for the first time outlines the profile of acupuncture treatable conditions in the US and is valuable for strategic planning in acupuncture training, healthcare administration and public education. PMID- 30298750 TI - Weight management services for an underserved population: a rapid review of the literature. AB - INTRODUCTION: Overweight and obesity (OW/OB) rates are increasing among Canadian children and youth, with rates currently affecting one-third of 5-17 year olds. OW/OB is associated with numerous physical and psychosocial consequences, which are compounded when a child has a pre-existing disability. This is concerning considering children with disabilities experience OW/OB at two to three times the rate of their typically developing peers. While the number of weight management programs have been increasing, they are generally designed to meet the needs of typically developing children and often exclude children with disabilities. This review identifies existing weight management programs for youth with disabilities, and examines their characteristics and outcomes. METHODS: A scoping review was conducted using rapid review principles. Three health and social science databases were searched using terms related to "disabilities", "obesity", and "weight management", limited to 2007-2017. Articles meeting the inclusion criteria were summarized and analyzed thematically. RESULTS: Five articles met inclusion criteria, and described four separate weight management programs. All included children and youth with intellectual disabilities, with one including children with physical disabilities. Programs had three traits in common: (1) utilizing inter/multidisciplinary teams; (2) using technology to deliver the program; and (3) engaging the family during the entire program. All articles reported that the programs reduced body mass index. CONCLUSION: The scarcity of programs designed to meet the unique needs of youth with disabilities is alarming. Although a robust evidence base is lacking, current research provides some directions into components that should be considered when designing future interventions. Implications for Rehabilitation 1. Clinicians should be aware of the high prevalence of overweight and obesity and the resultant consequences in children with disabilities. 2. The use of inter/multidisciplinary teams, technology, and family engagement all appear to be promising approaches to creating successful weight management programs: a. Weight-management programs should utilize inter/multidisciplinary teams to consider physical, social and psychological aspects of weight and health, to allow treatment plans to encompass a wider range of suggestions and recommendations. b. Health care providers should consider using technology as a platform to deliver weight-management programs and services and/or to directly track progress. c. Families are powerful agents of change, and should be consulted and involved in the delivery of weight-management programs. PMID- 30298751 TI - Adipose-derived Stem/Stromal Cells on Electrospun Fibrin Microfiber Bundles Enable Moderate Muscle Reconstruction in a Volumetric Muscle Loss Model. AB - Current treatment options for volumetric muscle loss (VML) are limited due to donor site morbidity, lack of donor tissue, and insufficient functional recovery. Tissue-engineered skeletal muscle grafts offer the potential to significantly improve functional outcomes. In this study, we assessed the potential pro myogenic effects of human adipose-derived stem cells (ASCs) seeded onto electrospun uniaxially aligned fibrin hydrogel microfiber bundles. Although both uninduced and 5-azacytidine-induced ASCs exhibited alignment, elongation, and diffuse muscle marker expression when grown on microfiber bundles for 2 months in vitro, both groups failed to fully recapitulate myotube characteristics. To assess the muscle regeneration potential of ASCs in vivo, ASC-seeded fibrin microfiber bundles were implanted in a robust murine VML defect model. Minimal fibrosis was observed surrounding implanted acellular hydrogel fibers at 2 and 4 weeks, and fibers seeded with ASCs exhibited up to 4 times higher volume retention than acellular fibers. We observed increased numbers of cells positive for the regenerating muscle marker embryonic myosin and the mature muscle marker myosin heavy chain in ASC-seeded fibers compared with acellular fibers at 1 and 3 months post-transplantation. Regenerating muscle cells were closely associated with ASC-derived cells and in some cases had potentially fused with them. These findings demonstrate that despite failing to undergo myogenesis in vitro, ASCs combined with electrospun fibrin microfibers moderately increased muscle reconstruction in vivo compared with acellular fibers following a severe VML defect. PMID- 30298752 TI - Deep Brain Stimulation for Amelioration of Cognitive Impairment in Neurological Disorders: Neurogenesis and Circuit Reanimation. AB - Acute (e.g., traumatic brain injury or stroke) and chronic (e.g., dementia or Parkinson's disease dementia) neurological disorders that involve cognitive impairment and dysfunctional neural circuits always lead to a dreadful and costly experience for patients and their families. The application of deep brain stimulation for the treatment of neuropsychiatric disorders has shown great potential to modulate pathological neural circuits and trigger endogenous neurogenesis. We summarize several important clinical and translational studies that utilize deep brain stimulation to improve cognition based on the potentiation of neural plasticity and neurogenesis. In addition, we discuss the neuroanatomy and cerebral circuits implicated in such studies as well as the potential mechanisms underlying therapeutic benefits. PMID- 30298753 TI - Implantation of the argus sling in a hard-to-treat patient group with urinary stress incontinence. AB - INTRODUCTION: Awareness of prostate cancer is growing in the Western population, and an increasing number of patients are being referred to prostate surgery. This is a significant contributor to male stress urinary incontinence (SUI). Implantation of an artificial sphincter (AUS) is considered the gold standard treatment of SUI. This study investigates the role of minimally invasive treatment with the Argus sling in a heterogenic hard-to-treat patient group. METHOD: The study was a retrospective follow-up study with patients as their own controls. Forty-one patients were enrolled and treated with the Argus sling. Patients enrolled had persisting SUI after prostate surgery for more than 12 months, despite conservative treatment. The pre-operative daily usage of pads and the 24 hours urinary leakage were compared to the post-operative findings. The primary goal was to achieve complete continence or a reduction of more than 50% in pad usage or urinary leakage. RESULTS: In total, 71% of the 41 patients enrolled met our primary objective. Complete continence was obtained in 56%, and a reduction of 50% or more was obtained in an additional 15%. CONCLUSION: This study has reproduced continence rates seen in previous studies, but in the hard to-treat patients with urgency or formerly failed surgery, the continence rate was found to be inferior. The AUS has produced similar results and must still be considered the gold standard treatment of SUI, but the Argus sling is an alternative for patients who want a passive system or for patients not suitable for AUS. PMID- 30298754 TI - Survey of Australian psychiatrists' and psychiatry trainees' knowledge about and attitudes towards medicinal cannabinoids. AB - OBJECTIVE: To assess Australian psychiatrists' and psychiatry trainees' knowledge about and attitudes towards medicinal cannabinoids, given the recent relaxation of cannabinoid-prescribing laws in Australia. METHOD: All Australian members of the Royal Australian and New Zealand College of Psychiatrists were invited to participate in an anonymous, 64-item online questionnaire, through Royal Australian and New Zealand College of Psychiatrists' newsletters. The questionnaire ran for a 10-week period from March to May 2017. Participants were asked about their knowledge of the evidence for and against prescribing pharmaceutical-grade cannabidiol and tetrahydrocannabinol, and their concerns about prescribing medicinal cannabinoids. RESULTS: In total, 88 doctors responded to the survey, with 55 completing all items (23 psychiatrists, 32 trainees). Overall, 54% of respondents would prescribe medicinal cannabinoids if it was legal to do so. Participants believed there was evidence for the use of cannabidiol and tetrahydrocannabinol in treating childhood epilepsy, chronic pain, and nausea and vomiting. They were most concerned about medicinal cannabinoids leading to psychotic symptoms, addiction and dependence, apathy and recreational use. CONCLUSIONS: Our sample of Australian psychiatrists and trainees were aware of the main clinical indications for medicinal cannabinoids, but were poor at differentiating between the indications for cannabidiol versus tetrahydrocannabinol. Further education about medicinal cannabinoids appears necessary. PMID- 30298755 TI - Association between DNA methylation of the KITLG gene and cortisol levels under stress: a replication study. AB - A recent study reported for the first time, that DNA methylation of the KITLG gene mediates the association between childhood trauma and cortisol stress reactivity. Our study aimed to provide the first independent replication of these findings. ESPRIT is a prospective study of community-dwelling participants (age >= 65), randomly selected from the electoral rolls of the Montpellier district, in France. Clinical depression was assessed using the Mini-International Neuropsychiatric Interview (MINI, French version 5.00), and the Centre for Epidemiological Studies Depression Scale (CES-D). Experiences of childhood adversity were ascertained via a 25-item questionnaire. Morning, evening, and diurnal salivary cortisol was measured under basal and stress conditions and determined using direct radioimmunoassay analysis. DNA methylation of the KITLG gene was quantified in whole blood using the SEQUENOM MassARRAY EpiTYPER platform. A significant negative association was observed between KITLG DNA methylation and both morning cortisol (beta = -1.846 +/- 0.666, p = .007) and diurnal cortisol (area under curve [AUC]) (beta = -19.429 +/- 8.868, p = .031) under a stress condition. However, only the former association was significant after correcting for multiple testing. Further, this association remained after adjusting for age, sex, and depression status. No significant association was observed between childhood trauma and KITLG DNA methylation in this older population. This study provides support for an association between KITLG methylation and stress cortisol levels, suggesting that DNA methylation of this gene may play a role in the longer term regulation of the stress system. Lay summary The significant negative association between KITLG DNA methylation and morning cortisol, measured under a stressful condition, suggests that individuals with higher KITLG methylation will secrete lower levels of cortisol whilst under stress. PMID- 30298756 TI - Corrigendum. PMID- 30298757 TI - Social anxiety and employment interviews: does nonverbal feedback differentially predict cortisol and performance? AB - BACKGROUND & OBJECTIVES: Interviewers often provide positive nonverbal feedback to reduce interviewees' anxiety. Socially anxious individuals typically harbor negative self-views discrepant with positive feedback. We examined whether nonverbal feedback and social anxiety jointly influence cortisol responses to, and performance during, interviews. DESIGN: An experimental between-subjects design randomly assigned participants to feedback condition. METHODS: Undergraduate students (N = 130) provided saliva and completed social anxiety, interview anxiety, and affective measures before a simulated interview. Following a standardized script, a confederate interviewer provided positive, ambiguous, or negative nonverbal feedback. Participants then provided saliva and completed self focused attention and self-awareness measures. Confederate interviewers and an external rater evaluated participants' anxiety displays, assertive behavior, and performance. RESULTS: Positive feedback decreased cortisol and improved performance for low social anxiety participants. Socially anxious participants exhibited higher cortisol but did not exhibit significant differences in performance after positive compared to negative feedback. CONCLUSIONS: Consistent with previous findings, positive feedback did not benefit socially anxious interviewees. Positive feedback increased physiological arousal relative to negative feedback but did not hinder performance among people high in social anxiety. These results provide novel information about the interactive influence of social anxiety and nonverbal interviewer feedback on arousal, self-focus, and interview performance. PMID- 30298758 TI - Managing the increasing diagnosis of papillary micro-cancer of thyroid. AB - There has been an increase in the incidence of thyroid cancer in the last decade, mainly due to the increase in imaging. A majority of the cases are for papillary cancers <1 cm. Mortality from thyroid cancer has stayed stable, thus, there is a large pool of papillary micro-cancer of thyroid in the general population without clinical significance. For these cancers a different approach is needed and active surveillance or less aggressive management should be offered as options. Controlled studies of minimally invasive procedures such as ethanol ablation are needed. If surgery is chosen, lobectomy alone should be adequate. Cases of occult papillary micro-cancer with local and distant metastases are very rare and should be managed according to the staging and risk category of the disease. PMID- 30298759 TI - Targeting pregnancy as a time to treat obesity. AB - Maternal obesity is recognized as one of the largest contributors to compromised health during pregnancy. Lifestyle interventions in obese pregnant women may be able to reduce gestational weight gain (GWG) but have shown limited success in improving pregnancy and neonatal outcomes. Lack of statistical power, poor compliance and inconsistency in inclusion BMI and setting across studies may be some of the reasons. Since pregestational BMI is the single most important predictor of obesity-related complications, the metabolic profile in the first trimester of pregnancy may play a very important role. Observational studies have shown that interpregnancy weight loss reduces the risk of macrosomia in a subsequent pregnancy. Future lifestyle randomized controlled trials should target the prepregnant state and examine the effect on maternal and neonatal outcomes. PMID- 30298760 TI - Bariatric surgery and diabetes remission: how far have we progressed? AB - Obesity and type 2 diabetes mellitus have been associated with higher morbidity and mortality. Bariatric surgery results in substantial and sustained weight loss in morbidly obese patients and improves obstructive sleep apnea. Furthermore, bariatric surgery improves diabetes control, hypertension, quality of life, stroke, myocardial infarction and reduces mortality. Interestingly, bariatric surgery induces high rates of short and long-term diabetes remission. While the exact mechanisms behind this are not completely understood, improved insulin action, beta-cell function and a complex interplay of hormones in the entero insular axis appear to play major roles. Insulin action improves proportionally to weight loss and it gets completely normalized especially after bilio pancreatic diversion. beta-Cell function also seems to improve after a variety of bariatric surgeries. Seemingly, baseline beta-cell function is able to predict future diabetes remission. This article will review the effectiveness of bariatric procedures on the remission and improvement of diabetes and its implicated mechanisms. PMID- 30298761 TI - Perinatal androgen exposure and adipose tissue programming: is there an impact on body weight fate? AB - Obesity is a major concern in public health because it is one of the main risk factors for the development of non-transmissible chronic diseases. The fact that there is a clear sex dimorphism in normal body fat distribution points out the role of sex steroids as key factors in the regulation and function of the adipose cell. Androgens affect adipogenesis and fat metabolism in the adipose tissue of males and females. Hormonal disorders during pregnancy may affect the fetal tissues, with long-term implications leading to the development of pathologies during adult life. Obesity and metabolic disease are among these. In this regard, animal models have demonstrated an abnormal fat distribution and modifications in the size and function of adipose cells in the female and male offspring of mothers exposed to androgen excess during pregnancy. PMID- 30298762 TI - Mass spectrometric analysis of steroids: all that glitters is not gold. AB - Steroid hormones are small molecules (MW around 300 Da) characterized by a large range of polarity and their analysis has always presented a serious challenge. Persistent problems with the specificity of conventional immunological methods are the cause of inconsistent results in the literature, a particularly problematic situation for healthcare decisions. At present, mass spectrometric methods have become the gold standard for accurate steroid profiling, and their advent will require the re-analysis of previously published data. However, it is a common misconception to consider the use of theses sophisticated technologies as a guarantee for accurate measures. Steroid analysis, especially in nervous tissues, indeed requires well-validated purification and separation steps before mass spectrometry, only then will mass spectrometric analysis be the absolute reference methodology. PMID- 30298763 TI - Romosozumab/CDP7851 for the treatment of osteoporosis. AB - Osteoporosis is an important worldwide health problem, conferring significant costs on healthcare. Current osteoporosis therapies are anti-resorptive and have proven anti-fracture efficacy, while there is a paucity of osteoanabolic therapies. Romosozumab is a humanized monoclonal antibody against sclerostin, an inhibitor of osteoblastic activity. Two-year follow-up data from initial clinical studies show rapid and robust increases in bone mineral density at all sites, except the wrist. Significant increases in bone formation markers have also been observed after administration of romosozumab. Notably, and unprecedented among any currently available therapy, this increase in bone formation is accompanied with control of bone resorption, allowing an enhanced anabolic potential compared with the only other currently available anabolic therapy, teriparatide. Romosozumab has been well tolerated in initial studies and its effects on BMD are augmented by follow-on anti-resorptive therapy. Ongoing Phase III studies will provide data regarding anti-fracture efficacy and comparisons with alendronate, as well as longer-term safety. PMID- 30298764 TI - Thyroid function in Down syndrome. AB - Down syndrome is the most commonly encountered human chromosomal disorder. Down syndrome is associated with thyroid dysfunction including: hypothyroidism, both congenital and acquired, and hyperthyroidism. A genetic predisposition and a propensity to acquire autoimmune disorders seem to be possible factors, though their causal relation remains unclear. The aim of the review is to describe what is currently known about the association between Down syndrome and thyroid dysfunction. PMID- 30298765 TI - Obesity and increased risk of esophageal adenocarcinoma. AB - There has been a substantial increase in the incidence of esophageal adenocarcinoma over the past 40 years. Meta-analyses of large prospective cohorts and population-based case-control studies demonstrate consistent associations between obesity and the development of adenocarcinoma of the esophagus and esophago-gastric junction, with an approximate doubling of risk of esophageal adenocarcinoma among patients who are obese, and an almost five-fold increased risk among those with BMI >40 kg/m2. The pathologic precursor, specialized intestinal metaplasia in Barrett's esophagus, is also associated with increased adiposity. Epidemiologic evidence suggests that this cancer risk is not solely due to increased gastro-esophageal reflux, and that adipose tissue itself, in particular visceral adipose, may fuel carcinogenesis through the production of adipokines, cytokines, growth factors, and increased inflammation. The robust epidemiologic evidence linking obesity with esophageal adenocarcinoma makes it an exemplar model for investigating the molecular mechanisms underpinning obesity associated malignant progression, which are discussed in this review. PMID- 30298766 TI - Outcome of complications in acromegaly patients after long-term disease remission. AB - Acromegaly patients suffer from pathologically high growth hormone (GH) and IGF-1 levels that in 99% of cases is due to a GH-producing pituitary adenoma. During active disease, GH excess is associated with a number of pathological conditions, such as hypertension, hypertrophic cardiomyopathy, sleep apnea, arthropathy, vertebral fractures and insulin resistance. After adequate treatment in the form of transsphenoidal surgery, radiotherapy, medical treatment or by a combination of these treatment modalities, several comorbid conditions improve considerably. However, despite long-term biochemical disease control, the prevalence of late manifestations of GH excess is high and significantly impair quality of life. In addition, there is evidence that adequate treatment is not able to normalize mortality risk in these patients. In this review, we critically evaluate the long term consequences of acromegaly after treatment, focusing on comorbid conditions, quality of life and mortality. We also discuss ongoing challenges in the management of acromegaly patients. PMID- 30298767 TI - Barriers to care for patients with diabetes in Durham, North Carolina, why are we withholding life-sustaining medications from the patients who need them the most? AB - The diabetes epidemic and its complications disproportionately affect minorities and the poor. Medical treatments that can prevent or delay diabetes complications are widely available but poverty underlies much of why there are disparities in diabetes care and outcomes. Lack of access to care, food insecurity and inability to pay for medications prevents adherence to a medication and lifestyle regimen that can be life-sustaining. At the very least, US policies should be changed to provide life-sustaining medications that prevent costly complications to patients who cannot afford them. Adopting value-based insurance design would benefit patients with diabetes who cannot afford to pay for medications but would also reduce healthcare costs in the long run. PMID- 30298768 TI - Fcgamma-receptor polymorphisms associated with clinical symptoms in patients with immunoglobulin G subclass deficiency. AB - BACKGROUND: Immunoglobulin G subclass deficiencies (IgGsd) are associated with recurrent respiratory tract infections. Immunoglobulin substitution therapy may be needed to prevent chronic lung tissue damage but tools for identifying the patients that will benefit from this treatment are still insufficient. Some FcgammaR polymorphisms seem to predispose for an increased risk for infections. In this study we wanted to evaluate if the FcgammaR-profile differs between individuals with IgGsd and a control population. METHODS: Single nucleotide polymorphisms (SNPs) of FcgammaRIIa, FcgammaRIIIa and FcgammaRIIc in 36 IgGsd patients and 192 controls with similar sex and geographical distribution were analyzed by TaqMan allelic discrimination assay or Sanger sequencing. RESULTS: In the IgGsd-group, homozygous frequency for FcgammaRIIa-R/R131 (low-binding capacity isoform) was higher (p = .03) as well as for non-classical FcgammaRIIc ORF (p = .03) and classical FcgammaRIIc-ORF tended (p = .07) to be more common compared to the controls. There was no difference between the groups regarding FcgammaRIIIa. CONCLUSION: The gene for classical FcgammaRIIc-ORF tended to be more frequent in individuals with immunoglobulin G subclass deficiency and the genes for non-classical FcgammaRIIc-ORF as well as low-binding capacity receptor FcgammaRIIa-R/R131 were more frequent. Further studies on the FcgammaR polymorphisms may pave way for identifying individuals that will benefit from immunoglobulin substitution. PMID- 30298769 TI - Comparator clinical trials of surrogate endpoints with albiglutide are in HARMONY. AB - Evaluation of: Ahren B, Johnson SL, Stewart M et al. HARMONY 3: 104-Week randomized, double-blind, placebo- and active-controlled trial assessing the efficacy and safety of albiglutide compared with placebo, sitagliptin, and glimepiride in patients with type 3 diabetes taking metformin. Diabetes Care 2014;37:2141-8 and Rosenstock J, Fonseca VA, Grass JL et al. Advancing basal insulin replacement in type 2 diabetes inadequately controlled with insulin glargine plus oral agents: a comparison of adding albiglutide, a weekly GLP-1 receptor agonist, versus thrice-daily prandial insulin lispro. Diabetes Care 2014;37:2317-25. Agonists of glucagon-like peptide-1 (GLP-1) receptors are used in the treatment of Type 2 diabetes. Albiglutide is a new long-acting GLP-1 receptor agonist being developed for once weekly use. This is an evaluation of two clinical trials in the HARMONY clinical trials series. HARMONY 3 compares albiglutide with sitagliptin and glimepiride in subjects with Type 2 diabetes poorly controlled with metformin, and HARMONY 6 compares albiglutide with insulin lispro in subjects poorly controlled with slow/medium release preparations of insulin. Both studies showed that albiglutide lowered HbA1c and had advantages over its comparator drugs. However, questions remain about the safety of albiglutide. Albiglutide is not being used in subjects with a history of thyroid cancer because it is not known whether this is a rare adverse effect with albiglutide. Also, the safety of albiglutide in subjects with Type 2 diabetes and high cardiovascular risk is unknown. PMID- 30298770 TI - Novel insights on the treatment of hypercholesterolemia. AB - The diagnosis of dyslipidemia is increasing both in adulthood and in childhood because of not only the steadily increasing prevalence of obesity but also a rise of medical attention in detecting unfavorable genetic conditions in patients of all ages. Attempts in lifestyle changes are frequently failing and thus the pharmacological treatment of dyslipidemia is spreading in medical practice to reduce cardiovascular risk. In childhood, statins are authorized by 8 years of age. Nevertheless, data on their long-term safety and efficacy are still lacking, especially in ones with high cardiovascular risk and/or primary dyslipidemia such as homozygous familial hypercholesterolemia, considerable as a mainly exclusively pediatric disease. Thus, new pharmacological approaches are needed and have to be evaluated in all categories of patients. In this context, the update and the critical revision of new medications have become a new duty for scientists and clinicians. PMID- 30298771 TI - Clinically meaningful end points in the evolving treatment paradigm for radioactive iodine-refractory differentiated thyroid cancer. AB - Radioactive iodine (RAI) is often used post-operatively for treatment of differentiated thyroid cancer (DTC), but many patients develop RAI-refractory disease. Patients with RAI-refractory DTC may be asymptomatic and stable for long periods of time, so identifying tumors that are no longer likely to respond to RAI treatment and determining when to transition to systemic therapy are critical issues for optimal patient care. The purpose of this paper is to review and assess the end points used in studies of RAI-refractory DTC in relation to the issues facing clinicians in transitioning patients to systemic therapy. Our goals are to provide a framework to help evaluate whether study results are clinically meaningful in guiding treatment decisions and to make recommendations to better define these end points for RAI-refractory DTC. PMID- 30298772 TI - Nutraceuticals for the treatment of metabolic diseases: evidence from clinical practice. AB - The aim of this review is to describe some types of supplements that have been shown to be good co-adjuvants along with diet and drug treatment in improving insulin resistance and dyslipidemia. We can conclude that some nutraceuticals, such as l-carnitine, berberine, omega-3 polyunsaturated fatty acids, krill oil and red yeast rice, can be helpful in reducing hypercholesterolemia or insulin resistance, as reported in clinical trials. Nutraceuticals can be associated with conventional pharmacological treatments to achieve an improved lipid profile without increasing statin dosage. Similarly, although nutraceuticals cannot replace conventional antidiabetic treatments, they may be useful as an adjuvant to standard therapy, improving insulin resistance. However, not all nutraceuticals are the same and their natural origin does not mean that everyone can take them or that they cannot be dangerous; nutraceuticals should be used only under medical prescription and should be combined with a well-balanced diet. PMID- 30298774 TI - Growth hormone replacement in patients with a history of malignancy: a review of the literature and best practice for offering treatment. AB - Previous studies have implicated the growth hormone (GH)/IGF-I axis as an important mediator of cancer risk in humans and animals. Evidence supporting this notion is derived from animal studies, epidemiological observations, patients with acromegaly and from therapeutic manipulation of GH and IGF-I actions. Therefore, the use of GH therapy in patients with a history of malignancy raises hypothetical safety concerns. Reassuringly, GH therapy in childhood cancer survivors has not been confirmed to increase the cancer risk. Conversely, the risk of occurrence of a second neoplasm may be increased, with meningiomas being the most common tumor. In light of these findings, we propose considering GH therapy to be based on each individual's circumstance and commenced at least 2 years after cancer remission is achieved with close monitoring during therapy. More long-term data are needed on the safety of GH replacement therapy in GH deficient adults with a history of malignancy. PMID- 30298773 TI - Predictive modeling for incident and prevalent diabetes risk evaluation. AB - With half of individuals with diabetes undiagnosed worldwide and a projected 55% increase of the population with diabetes by 2035, the identification of undiagnosed and high-risk individuals is imperative. Multivariable diabetes risk prediction models have gained popularity during the past two decades. These have been shown to predict incident or prevalent diabetes through a simple and affordable risk scoring system accurately. Their development requires cohort or cross-sectional type studies with a variable combination, number and definition of included risk factors, with their performance chiefly measured by discrimination and calibration. Models can be used in clinical and public health settings. However, the impact of their use on outcomes in real-world settings needs to be evaluated before widespread implementation. PMID- 30298775 TI - Thyroid surgery for treatment of Graves' disease complicated by ophthalmopathy: a comprehensive review. AB - Graves' disease (GD) is an autoimmune disorder in which antibodies directed against thyroid-stimulating hormone receptors leads to thyrotoxicosis. Graves' ophthalmopathy, a condition that occurs in up to half of GD patients, is a cause of significant morbidity and is potentially vision threatening. Three treatment options are equally effective for uncomplicated GD and these include thyroid surgery (thyroidectomy), radioactive iodine thyroid ablation and antithyroid drugs. However, recent practice surveys suggest that surgery is the least favored GD treatment. When GD is complicated by moderate-to-severe Graves' ophthalmopathy, antithyroid drugs and surgery are recommended by current guidelines, and again the preference for thyroid surgery in these cases has remained low. This report aims to review current published data regarding thyroidectomy as a treatment for GD, and in particular, we focus on the effects of thyroidectomy on Graves' ophthalmopathy development and progression. PMID- 30298776 TI - Therapeutic potential of miRNAs in diabetes mellitus. AB - miRNAs are major regulators of gene expression that are emerging as central players in the development of many human diseases, including diabetes mellitus. In fact, the manifestation of diabetes is associated with alterations in the miRNA profile in insulin-secreting cells, insulin target tissues and, in case of long-term diabetes complications, in many additional organs. Diabetes also results in changes in the profile of miRNAs detectable in blood and other body fluids. This has boosted an ever increasing interest in the use of circulating miRNAs as potential biomarkers to predict the development of diabetes and its devastating complications. Moreover, promising approaches to correct the level of selected miRNAs are emerging, permitting to envisage new therapeutic strategies to treat diabetes and its complications. PMID- 30298777 TI - Potential for dipeptidyl peptidase-4 inhibitor and sodium glucose cotransporter 2 inhibitor single-pill combinations. AB - With prolonged duration of Type 2 diabetes mellitus, most patients need a combination of antihyperglycemic drugs to reach their target HbA1c. Evidence shows that single-pill combinations (SPCs) may increase patient satisfaction, adherence, and reduce overall health-care costs. Several SPCs containing metformin and another oral antidiabetic drug (OAD) are available on the market. Although well established in clinical practice, long-term durability and tolerability of traditional OADs can be inadequate. Dipeptidyl peptidase (DPP)-4 inhibitors and sodium glucose cotransporter (SGLT) 2 inhibitors are two newer classes of OADs that are efficacious and are less likely to induce adverse effects such as gastrointestinal reactions, hypoglycemia and weight gain when compared with metformin, sulfonylureas, and thiazolidinediones. This article describes current efficacy and safety data of DPP-4/SGLT2 inhibitor combination therapy. Pharmacokinetics, mechanism-of-action based rationale for the combination and timing of the addition of a SPC to the treatment regimen are discussed. PMID- 30298778 TI - Phylogeography of Endangered Bitterling Acheilognathus melanogaster Endemic to Eastern Japan. AB - The bitterling Acheilognathus melanogaster is a critically endangered primary freshwater fish endemic to the Pacific side of eastern Japan. To elucidate A. melanogaster genetic structure, we investigated phylogeography in nine populations, using gene sequences of mitochondrial Cytochrome b (Cytb), as well as nuclear Rhodopsin (Rho) and glycosyltransferase (Glyt). We found four Cytb based geographical clusters unevenly divided between the northern and southern regions, with smaller groups in the south. Of the nuclear genes, Glyt did not show geographical differentiation, whereas Rho formed two clusters: one widely occurring and another restricted to central regions. Genetic diversity was generally higher in southern than in northern populations. Our results suggest that conservation of southern local populations is particularly important in maintaining the genetic diversity of this endangered fish. PMID- 30298779 TI - Genetic Diversity of MHC Class II DRB1 Exon 2 in the Red Fox (Vulpes vulpes) on Hokkaido, Japan. AB - To assess the genetic diversity of the red fox (Vulpes vulpes) population on Hokkaido Island, northern Japan, we examined genotypes of exon 2 of the major histocompatibility complex (MHC) class II DRB1 gene for 232 individuals and identified 17 novel alleles. The subpopulation in the Southern area was genetically differentiated from those in all other areas on Hokkaido, suggesting isolation in southern Hokkaido. In addition, the Southern subpopulation is lower in genetic diversity than the other subpopulations, possibly resulting from purifying selection and/or a recent bottleneck. The non-synonymous substitutions exceeded the synonymous substitutions for codons encoding antigen-binding sites (ABSs) in exon 2, indicating that the red fox DRB1 alleles have evolved under positive selection. In a Bayesian phylogenetic tree, although most of the DRB1 alleles from the Hokkaido red fox were contained within a red fox-like canid (Vulpes) clade, some belonged to another canid clade. This means trans-species polymorphism maintained by balancing selection. Our results showed the local variability and the presence of selection on the MHC gene in this population, which contributes to the understanding of the historical background and the molecular evolution. PMID- 30298780 TI - A New Species of Sulcospira (Gastropoda: Pachychilidae) from Hunan, China. AB - A new species of pachychilid freshwater gastropod, Sulcospira hunanensis sp. nov., is described from Hunan Province, China, based on morphological and molecular evidence. The new species is distinguished from its congeners by a combination of characters, including elongated shell with eight to nine whorls, spiral whorls with ribs, and stomach with outer and inner crescentic pads not connected to each other. Sulcospira hunanensis sp. nov. is the first confirmed report of this genus from Hunan Province, China. It is anticipated that further species will be found in this region, which currently remain unknown. Furthermore, based on morphological and molecular evidence, this study is the first record of Sulcospira tonkiniana in Guangxi Zhuang Autonomous Region, China, with Sulcospira krempfi supported as a synonym of Sulcospira tonkiniana. PMID- 30298781 TI - Binucleation of Accessory Gland Lobe Contributes to Effective Ejection of Seminal Fluid in Drosophila melanogaster. AB - The adult male accessory gland in insects is an internal reproductive organ analogous to the mammalian prostate, and secretes various components in the seminal fluid. Products of the accessory gland in the fruit fly Drosophila melanogaster are known to control reproductive behaviors in mated females, such as food uptake, oviposition rate, and rejection of re-mating with other males, all of which increase male reproductive capacity. Production of larger amounts of accessory gland products is thus thought to result in higher male reproductive success. The epithelium of the Drosophila accessory gland lobe is composed of a unique population of binucleate cells. We previously predicted, based on measurements of cell size in mono/binucleate mosaic accessory glands, that binucleation results in a higher plasticity in cell shape, enabling more effective ejection of seminal fluid. However, the actual effect of binucleation on ejection of seminal fluid or reproductive capacity remained unclear, as we were unable to generate an organ with uniformly mononucleate cells. In the present study, we generated organs in which most of the epithelial cells are mononucleate by manipulating aurora B or fizzy-related to block binucleation. Mononucleation resulted in a less elastic accessory gland lobe, which decreased ejection volume and the oviposition of mated females; these effects were particularly pronounced over the long term. These results suggest that binucleation in accessory gland epithelial cells contributes to higher plasticity in the volume of this organ, and enhances male reproductive success through enabling ejection of larger amounts of seminal fluid. PMID- 30298782 TI - Ultraviolet Reflectance Structures of Peacock Feathers. AB - Male peacock (Pavo cristatus) tail feathers have an eyespot pattern with an inconspicuous black or dark blue center surrounded by brilliant, structural colors, such as blue, light brown, and yellow-green. Under ultraviolet A (UVA), the central part of the eyespot reflects UVA better than the surrounding parts. Herein, I examined various areas of eyespots on paraffin sections of feathers using an optical microscope, and characterized positional relationships between barbs and barbules. These analyses confirmed that barbules in the central part of the eyespot are in a horizontal position with respect to the barb, and that light transmission from the central part is less than that from the other parts. In addition, I compared microstructures of barbules in the central part of eyespot with those in surrounding areas using transmission electron microscope analysis. The melanin rods in the barbules reflecting yellow-green color comprise several ordered lattice structures. In contrast, melanin rods in the central part of the eyespot were only distributed in 1-3 layers on a part of the front side of the barbules. I also demonstrated that keratin structures of barbules are homogeneous in the central part of the eyespot, but have fibrous structures with many voids in the yellow-green parts. Collectively, the present observations suggest that feathers in the central part of the eyespot reflect UVA depending on the direction of irradiation, and these properties are governed by configurations of barbules relative to barbs, melanin rod distributions, and the presence of keratin structures with gaps.

AB - The systematic status of the stygobitic amphipod, Paramoera relicta Ueno, 1971, was revisited based on morphological examination of the paratypes, and molecular phylogenetic analyses using a newly collected specimen from its type locality. The paratypes clearly showed that this species does not possess the "sinusoid" antennal sinus in the head, which was erroneously described in the original description of this species; P. relicta is unquestionably classified within the genus Paramoera Miers, 1875 . Molecular phylogenetic trees obtained with nuclear histone H3 and mitochondrial 16S rRNA demonstrated that P. relicta clearly belongs to the clade consisting of Paramoera species. Since the genus Relictomoera Barnard and Karaman, 1982 was erected according to the "sinusoid" characteristic of its type species P. relicta, this genus is no longer valid, and should be treated as a junior subjective synonym of Paramoera. One of the paratypes of P. relicta is herein designated as a neotype for the species to clarify its taxonomic status and emend the morphological characteristics of this pontogeneiid amphipod. PMID- 30298784 TI - Microscopic and Submicroscopic Gradient Variation of Olfactory Systems among Six Sinocyclocheilus Species Living in Different Environments. AB - The fish genus Sinocyclocheilus contains many different species that inhabit diverse natural environments, such as surface water layer, cave, or intermediate. As a result of these different habitats there are some differences in their sensory systems. Microscopic and submicroscopic structures of olfactory systems in six representative species of Sinocyclocheilus were studied, including one surface-dwelling species (S. grahami), two intermediate species (S. jii and S. macrophthalmus) and three cave-dwelling species (S. brevibarbatus, S. anshuiensis, and S. tianlinensis). Due to adaptive evolution under extreme environmental conditions, cave-dwelling species have more developed olfactory systems. We observed that, compared with surface-dwelling species, the olfactory sac of the cave-dwelling Sinocyclocheilus species has the following characteristics: higher density of cilia, greater length of sensory cilia, many other special structures (micro-ridge, olfactory islet, rod cilia). These results reveal different levels of olfactory system development, consistent with the view that that cave-dwelling species have more developed olfactory systems than intermediate and surface-dwelling species. PMID- 30298785 TI - Does Nest Predation Influence Colony Movements of Saunders's Gulls (Saundersilarus saundersi) in a Reclaimed Land Area? AB - Some seabirds commonly use artificially reclaimed lands, which are frequently located next to mainland environments, for breeding. Nest predation risk caused by birds or mammals from the mainland has negative influence on fitness-related costs and distribution of seabirds. Here, we sought to link potential factors, specifically those related to nest predation and nest environment, with breeding performance and colony movements of the Saunders's gull (Saundersilarus saundersi), a vulnerable species, on a large reclaimed area (1350 ha) in Incheon in Republic of Korea. This reclaimed area has experienced rapid changes in communities of nest predators from the mainland and vegetation ranging from halophytes to terrestrial plants after reclamation. Additionally, changes in the surrounding of used nest sites were retrospectively examined to determine whether colony movement was reversible in this reclaimed area. Our results indicated that high nest predation in a previous year induced colony movements in a consecutive year while the breeding colony exhibited a gradual reduction in clutch size. However, such movement after high nest predation seemed to be irreversible due to ongoing habitat degradation caused by construction and vegetation alteration. This study highlights that high nest predation may exert strong pressure on breeding colonies of Saunders's gulls. It also has anthropogenic impacts, leading to continuous dispersal of colonies to new areas for this vulnerable seabird in a reclaimed land. PMID- 30298786 TI - Rediscovery after Almost 120 Years: Morphological and Genetic Evidence Supporting the Validity of Daphnia mitsukuri (Crustacea: Cladocera). AB - We examined the morphology of Daphnia individuals maintained in our laboratory for several years, originally collected in Lake Inbanuma, Chiba, Japan. We determined partial sequences of the mitochondrial cytochrome c oxidase subunit I and 12S rRNA genes from specimens in the cultured material. These animals are morphologically similar to D. obtusa Kurz, 1874 , but genetically distinct from this species. Our detailed observation shows that the morphological characteristics in the female and male individuals of our material are highly congruent with those of D. mitsukuri Ishikawa, 1896 , which has not been identified positively for more than 120 years since its original description, with its taxonomic identity having been questioned for almost 90 years. Based on our morphological and genetic data, we conclude that D. mitsukuri should be regarded as a taxonomically valid species. A search among public DNA sequence databases suggests D. mitsukuri is also distributed in China, although these Chinese sequences have been labeled as 'Daphnia pulex', representing misidentification. PMID- 30298787 TI - Molecular Phylogeny of the Family Capitellidae (Annelida). AB - Capitellids have emerged as monophyletic in most but not all recent molecular phylogenies, indicating that more extensive taxon sampling is necessary. In addition, monophyly of most or all capitellid genera was questionable, as some diagnostic characters vary ontogenetically within individuals. We tested the monophyly of Capitellidae and eight capitellid genera using phylogenetic analyses of combined 18S, 28S, H3, and COI gene sequences from 36 putative capitellid species. In our trees, Capitellidae formed a monophyletic sister group to Echiura, and Capitella was also monophyletic, separated by a long branch from other capitellids. Well-supported clades each containing representatives of different genera, or containing a subset of species within a genus, indicated that Barantolla, Heteromastus, and Notomastus are likely not monophyletic. We mapped three morphological characters traditionally used to define capitellid genera (head width relative to width of first segment, number of thoracic segments, and number of segments with capillary chaetae) onto our tree. While Capitella showed unique character states, states in the other genera were decidedly not phylogenetically informative. Morphology-based capitellid taxonomy will require a fine-scale reevaluation of character states and detection of new characters. PMID- 30298788 TI - Genetic Diversity among Clouded Salamanders (Hynobius nebulosus) in Shiga Prefecture. AB - The Japanese clouded salamander (Hynobius nebulosus) is a lentic-breeding species distributed throughout western Japan. Threats, such as habitat loss, have led to it being categorized as a vulnerable species. To explore the phylogeographic features and population differentiation among clouded salamanders in Shiga prefecture, we analyzed sequences of the mitochondrial cytochrome b gene. DNA samples were collected from 29 distinct breeding sites, and 53 cytochrome b haplotypes were identified. On the basis of comparison of the composition and frequency of haplotypes in each breeding site, salamanders in each habitat appeared to have distinct characteristics. Significant genetic differentiation was observed in 93.3% of possible pairs of habitats in Shiga prefecture, and 67.7% of habitat pairs within the same locality were found to be significantly different. These results suggest that the salamanders' poor locomotion combined with topographic effects may have contributed to the diversity of locally distributed salamanders in Shiga. Phylogenetic analysis showed that haplotypes of H. nebulosus in Shiga can be divided into five groups (the Nagahama-Maibara group, Otsu group, Konan group 1, Konan group 2, and Takashima group), each with a distinct geographical distribution. Haplotypes of the Otsu group, however, were exceptionally widely distributed. The results of the present study will contribute to the future of H. nebulosus conservation management in Shiga. PMID- 30298789 TI - The way others move can influence what we choose. AB - Whether pointing at a menu item or rifling through a clothes rack, when we choose we often move. We investigated whether people's tendency to copy the movements of others could influence their choices. Participants saw pairs of pictures in private and indicated which one they preferred. They then entered a virtual art gallery and saw the same picture pairs in the presence of a virtual character. Having observed the virtual character point to indicate her preference with either a high or low movement trajectory, participants indicated their preference. There was either an anatomical (same movement, same choice) or spatial correspondence (same movement, different choice) between the participant's pictures and those of the virtual character. We found that participants copied the movement made by the virtual character rather than her action goal (i.e., her choice of picture). This resulted in a shift towards the virtual character's preferences in the anatomical condition but away from her preferences in the spatial condition. This effect was driven by the observation of the virtual character's high pointing movements. In a further experiment, we did not find any significant differences in imitation behaviour in autism, although autistic participants were less consistent in their choices. Our findings demonstrate that we are not only influenced by other's choices but also the types of movements others make to indicate those choices. PMID- 30298790 TI - BabA-mediated adherence of pediatric ulcerogenic H. pylori strains to gastric mucins at neutral and acidic pH. AB - Helicobacter pylori infection can result in non-ulcer dyspepsia (NUD), peptic ulcer disease (PUD), adenocarcinoma, and gastric lymphoma. H. pylori reside within the gastric mucus layer, mainly composed of mucins carrying an array of glycan structures that can serve as bacterial adhesion epitopes. The aim of the present study was to characterize the binding ability, adhesion modes, and growth of H. pylori strains from pediatric patients with NUD and PUD to gastric mucins. Our results showed an increased adhesion capacity of pediatric PUD H. pylori strains to human and rhesus monkey gastric mucins compared to the NUD strains both at neutral and acidic pH, regardless if the mucins were positive for Lewis b (Leb), Sialyl-Lewis x (SLex) or LacdiNAc. In addition to babA positive strains being more common among PUD associated strains, H. pylori babA positive strains bound more avidly to gastric mucins than NUD babA positive strains at acidic pH. Binding to Leb was higher among babA positive PUD H. pylori strains compared to NUD strains at neutral, but not acidic, pH. PUD derived babA-knockout mutants had attenuated binding to mucins and Leb at acidic and neutral pH, and to SLex and DNA at acidic pH. The results highlight the role of BabA-mediated adherence of pediatric ulcerogenic H. pylori strains, and points to a role for BabA in adhesion to charged structures at acidic pH, separate from its specific blood group binding activity.

AB - Pregnancy represents a time of increased risk for intimate partner violence (IPV), and an HIV diagnosis further increases the vulnerability of this at-risk group. This study explores experiences of recent IPV using qualitative interviews with N = 12 HIV-positive pregnant women recruited from a clinical setting in South Africa, a location with a high global prevalence of IPV and HIV. Partner dynamics around IPV resulted in HIV shame and stigma and adversely affected engagement in HIV care and HIV treatment behaviors. The results highlight the challenges women face in navigating disclosure of both IPV and HIV, accessing necessary support, and engaging in both HIV-related and pregnancy-related care in the context of an abusive relationship. PMID- 30298794 TI - Identifying treatment responders using counterfactual modeling and potential outcomes. AB - Individualizing treatment according to patients' characteristics is central for personalized or precision medicine. There has been considerable recent research in developing statistical methods to determine optimal personalized treatment strategies by modeling the outcome of patients according to relevant covariates under each of the alternative treatments, and then relying on so-called predicted individual treatment effects. In this paper, we use potential outcomes and principal stratification frameworks and develop a multinomial model for left and right-censored data to estimate the probability that a patient is a responder given a set of baseline covariates. The model can apply to RCT or observational study data. This method is based on the monotonicity assumption, which implies that no patients would respond to the control treatment but not to the experimental one. We conduct a simulation study to evaluate the properties of the proposed estimation method. Results showed that the predictions of the probability of being a responder were well calibrated even if we observed variability and a small bias when many parameters were estimated. We finally applied the method to a cohort study on the selection of patients for additional radiotherapy after resection of a soft-tissue sarcoma. PMID- 30298795 TI - Beck Depression Inventory-II: Self-report or interview-based administrations show different results in older persons. AB - : ABSTRACTBeck Depression Inventory-II (BDI-II) is one of the most-used rating scales. It was developed as a tool administered either as a self-rating or interview-based, observer-rating scale. OBJECTIVE: The goal of this study is to compare BDI-II scores obtained with two standard methods of administration in community-based older persons. METHODS: BDI-II was administered at first in the self-rated version to a sample of 60 mentally healthy older persons (age 60-87 years). Afterward, the interview-based administration was performed. ANALYSES: We compared the scores with nonparametric tests - Spearman's correlation coefficient and Wilcoxon Signed Ranks test. We also computed internal consistency. RESULTS: Self-rated BDI-II yielded significantly higher total score than interview (p < 0.001, P = 88%). The correlation between total scores was moderate (rs = 0.46, p < 0.001). Item analysis revealed a larger decrease (lower scores) in the somatic items in the interview-based version. CONCLUSIONS: The two methods of administration result in different total score in healthy older persons. Therefore, interpretation of the scores should reflect the administration, which should be always specified in the studies. PMID- 30298796 TI - Intra-household double burden of malnutrition in a North African nutrition transition context: magnitude and associated factors of child anaemia with mother excess adiposity. AB - OBJECTIVE: In the Middle East and North Africa region, the nutrition transition has resulted in drastic increases in excess adiposity, particularly among women, while some types of undernutrition remain prevalent, especially among pre-school children. We assessed the magnitude, nature and associated factors of the within household co-occurrence of anaemia in children and excess adiposity in mothers. DESIGN: Cross-sectional survey using stratified two-stage random cluster sampling to survey households with women aged 20-49 years. BMI>=25.0 kg/m2 defined overweight and BMI>=30.0 kg/m2 obesity, while anaemia for children was defined as Hb<110 g/l. The associations between child anaemia and mother excess adiposity, and sociodemographic and lifestyle factors were estimated by multinomial regression. SETTING: Greater Tunis area, Tunisia, in 2009-2010. SUBJECTS: Children aged 6-59 months living with their 20-49-year-old mothers (437 child mother pairs). RESULTS: The most prevalent double burden of malnutrition in child mother pairs by far was the anaemic child and overweight mother (24.4 %; 95 % CI 20.1, 29.3 %). A significant proportion of pairs were anaemic child and obese mother (14.4 %; 95 % CI 11.0, 18.5 %). The co-occurrence of anaemia in child and excess adiposity in mother was neither synergetic nor antagonistic (P=0.59 and 0.40 for anaemia-overweight and anaemia-obesity, respectively). This double burden was more frequent among child-mother pairs with younger children, with mothers of higher parity and higher energy intakes. CONCLUSIONS: The high prevalence of anaemic child and overweight or obese mother requires special attention e.g. through interventions which simultaneously target both types of malnutrition within the same household. PMID- 30298797 TI - Who Is (Still) Looking After Mom and Dad? Few Improvements in Care Aides' Quality of-Work Life. AB - ABSTRACTUnregulated care aides provide most of the direct care to nursing home residents. We previously reported the first demographic profile of care aides in Western Canada through the Translating Research in Elder Care (TREC) longitudinal research program (2007-2022) in applied health services. Here we describe demographic, health, and work life characteristics of aides from 91 nursing homes in Western Canada. Demographics and work life varied significantly across health regions and facility owner-operator models. Our longitudinal cohort of aides from Alberta and Winnipeg had higher emotional exhaustion (a negative attribute), professional efficacy (a positive attribute), and experience of dementia-related responsive behaviours from residents. Overall, results indicate little improvement or worsening of care aide health and quality of work life. Coupled with limited provincial or national initiatives for workforce planning and training of these workers, this signals a long-term care system ill-prepared to care effectively for Canada's aging population. PMID- 30298798 TI - The tip of the iceberg: incompleteness of measles reporting during a large outbreak in The Netherlands in 2013-2014. AB - Measles is a notifiable disease, but not everyone infected seeks care, nor is every consultation reported. We estimated the completeness of reporting during a measles outbreak in The Netherlands in 2013-2014. Children below 15 years of age in a low vaccination coverage community (n = 3422) received a questionnaire to identify measles cases. Cases found in the survey were matched with the register of notifiable diseases to estimate the completeness of reporting. Second, completeness of reporting was assessed by comparing the number of susceptible individuals prior to the outbreak with the number of reported cases in the surveyed community and on a national level.We found 307 (15%) self-identified measles cases among 2077 returned questionnaires (61%), of which 27 could be matched to a case reported to the national register; completeness of reporting was 8.8%. Based on the number of susceptible individuals and number of reported cases in the surveyed community and on national level, the completeness of reporting was estimated to be 9.1% and 8.6%, respectively. Estimating the completeness of reporting gave almost identical estimates, which lends support to the credibility and validity of both approaches. The size of the 2013-2014 outbreak approximated 31 400 measles infections. PMID- 30298799 TI - Bovine tuberculosis in working foxhounds: lessons learned from a complex public health investigation. AB - In 2017, Public Health England South East Health Protection Team (HPT) were involved in the management of an outbreak of Mycobacterium bovis (the causative agent of bovine tuberculosis) in a pack of working foxhounds. This paper summarises the actions taken by the team in managing the public health aspects of the outbreak, and lessons learned to improve the management of future potential outbreaks. A literature search was conducted to identify relevant publications on M. bovis. Clinical notes from the Public Health England (PHE) health protection database were reviewed and key points extracted. Animal and public health stakeholders involved in the management of the situation provided further evidence through unstructured interviews and personal communications. The PHE South East team initially provided 'inform and advise' letters to human contacts whilst awaiting laboratory confirmation to identify the infectious agent. Once M. bovis had been confirmed in the hounds, an in-depth risk assessment was conducted, and contacts were stratified in to risk pools. Eleven out of 20 exposed persons with the greatest risk of exposure were recommended to attend TB screening and one tested positive, but had no evidence of active TB infection. The number of human contacts working with foxhound packs can be large and varied. HPTs should undertake a comprehensive risk assessment of all potential routes of exposure, involve all other relevant stakeholders from an early stage and undertake regular risk assessments. Current guidance should be revised to account for the unique risks to human health posed by exposure to infected working dogs. PMID- 30298800 TI - Association of cognitive impairment and grip strength trajectories with mortality among middle-aged and elderly adults. AB - : ABSTRACTBackground:This study investigates whether maintaining high levels of cognitive impairment and weak grip strength will predict a higher risk for mortality. METHODS: Data from the Korean Longitudinal Study of Aging (KLoSA) from 2006 to 2014 was assessed using longitudinal data analysis and included 5,812 research subjects. Our modeling approach jointly estimated multi-period trajectories of grip strength and cognitive impairment, and the primary analysis was based on Cox proportional hazards models. RESULTS: A four-class linear solution fit the data best in both cognitive impairment and grip strength based on the model fitness, respectively. The hazard ratio (HR) of mortality in group 1 (consistently low) of cognitive impairment and of grip strength were 2.114 times higher (p-value 0.001) and 3.405 times higher (p-value <.0001) compared with group 3 (consistently high) and group 4 (consistently high), respectively. CONCLUSION: This study provides insightful scientific evidence into the specificity of longitudinal changes in grip strength and cognitive impairment on mortality. Our findings suggest that declined cognitive ability and weak grip strength are predictors of mortality in older Korean people.

AB - Scrub typhus and Japanese spotted fever-both rickettsial diseases-are endemic and notifiable in Japan and may cause a fatal outcome without prompt treatment. Here we present the first case of a concurrent sympatric infection of both diseases with grade II evidence. A 67-year-old woman, after a single event of potential exposure to the pathogens, presented with a 12-day history of fever, pharyngeal pain, papulo-erythematous rash, and pronounced fatigue. Her erythematous rash was distributed on her trunk and extremities, palms, and soles and eventually progressed to purpura. Fever persisted until doxycycline was administered on day 12. A significant > 4-fold increase in IgG and IgM titers against multiple serotypes of Orientia tsutsugamushi and Rickettsia japonica were revealed by indirect immunoperoxidase assays. These clinical and serological data, even in the absence of molecular or isolation evidence, provided grade II evidence that this was a concurrent infection of sympatric scrub typhus and Japanese spotted fever. PMID- 30298802 TI - Soil-Transmitted Helminth Infections and Anemia in Schoolchildren from Corn Island Archipelago (RAAS, Nicaragua). AB - The prevalence and intensity of soil-transmitted helminth (STH) infections in schoolchildren from Corn Islands (Nicaragua) were examined to detect mono- or poly-STH infected children, measuring different intensity levels, and to elucidate measurably increased odds of being anemic. A total of 341 stool samples provided by 2- to 15-year-old children were examined using a concentration technique and a Kato-Katz slide. Intensity of infection was expressed as eggs per gram (epg) of feces to classify light, moderate, or heavy intensity infection. A finger-prick blood sample was obtained from each student in the field. Soil transmitted helminth prevalence was 54.3%, with Trichuris trichiura as the most prevalent species (48.9%). The combination T. trichiura/Ascaris lumbricoides (12.6%) was the most common. When T. trichiura or A. lumbricoides appeared as a single infection, light or moderate intensity infections were seen, whereas when multiple species were identified, heavy infections were present. Anemia was detected in those with any kind of STH infection (42.7%), with statistically significant differences (P = 0.004) when compared with uninfected individuals (28.2%). Polyparasite infection with one parasite species at moderate intensity and the other parasite species at light intensity or absent was found to be a significant factor for the odds of being anemic (odds ratio = 2.07). The present study reveals a high level of STH transmission requiring a deworming control program in Corn Islands and pointing to the need of improving the education and sanitary conditions of the population to avoid environmental contamination and reinfection. PMID- 30298803 TI - A Low-Cost, Community Knowledge Approach to Estimate Maternal and Jaundice Associated Mortality in Rural Bangladesh. AB - In the absence of a civil registration system, a house-to-house survey is often used to estimate cause-specific mortality in low- and middle-income countries. However, house-to-house surveys are resource and time intensive. We applied a low cost community knowledge approach to identify maternal deaths from any cause and jaundice-associated deaths among persons aged >= 14 years, and stillbirths and neonatal deaths in mothers with jaundice during pregnancy in five rural communities in Bangladesh. We estimated the method's sensitivity and cost savings compared with a house-to-house survey. In the five communities with a total of 125,570 population, we identified 13 maternal deaths, 60 deaths among persons aged >= 14 years associated with jaundice, five neonatal deaths, and four stillbirths born to a mother with jaundice during pregnancy over the 3-year period before the survey using the community knowledge approach. The sensitivity of community knowledge method in identifying target deaths ranged from 80% for neonatal deaths to 100% for stillbirths and maternal deaths. The community knowledge approach required 36% of the staff time to undertake compared with the house-to-house survey. The community knowledge approach was less expensive but highly sensitive in identifying maternal and jaundice-associated mortality, as well as all-cause adult mortality in rural settings in Bangladesh. This method can be applied in rural settings of other low- and middle-income countries and, in conjunction with hospital-based hepatitis diagnoses, used to monitor the impact of programs to reduce the burden of cause-specific hepatitis mortality, a current World Health Organization priority.

High-throughput screening of antibodies from well-characterized cohorts offers a means to substantially improve existing assays by rationally choosing the most informative sets of responses and analytical methods. Recent data suggest that high-resolution information on malaria exposure can be obtained from a small number of samples by measuring a handful of properly chosen antibody responses. In this review, we discuss how standardized multi-antibody assays can be developed and efficiently integrated into existing surveillance activities, with potential to greatly augment the breadth and quality of information available to direct and monitor malaria control and elimination efforts.

AB - Entamoeba histolytica is a protozoan parasite that causes amebiasis and poses a significant health risk for populations in endemic areas. The molecular mechanisms involved in the pathogenesis and regulation of the parasite are not well characterized. We aimed to identify and quantify the differentially abundant membrane proteins by comparing the membrane proteins of virulent and avirulent variants of E. histolytica HM-1:IMSS, and to investigate the potential associations among the differentially abundant membrane proteins. We performed quantitative proteomics analysis using isobaric tags for relative and absolute quantitation labeling, in combination with two mass spectrometry instruments, that is, nano-liquid chromatography (nanoLC)-MALDI-MS/MS and nanoLC-electrospray ionization tandem mass spectrometry. Overall, 37 membrane proteins were found to be differentially abundant, whereby 19 and 18 membrane proteins of the virulent variant of E. histolytica increased and decreased in abundance, respectively. Proteins that were differentially abundant include Rho family GTPase, calreticulin, a 70-kDa heat shock protein, and hypothetical proteins. Analysis by Protein ANalysis THrough Evolutionary Relationships DB revealed that the differentially abundant membrane proteins were mainly involved in catalytic activities (29.7%) and metabolic processes (32.4%). Differentially abundant membrane proteins that were found to be involved mainly in the catalytic activities and the metabolic processes were highlighted together with their putative roles in relation to the virulence. Further investigations should be performed to elucidate the roles of these proteins in E. histolytica pathogenesis. PMID- 30298806 TI - Hymenolepis nana-An Emerging Intestinal Parasite Associated with Anemia in School Children from the Bolivian Chaco. AB - Tropical anemia can have multiple causes, whether socioeconomic, dietary, or infectious. In the Bolivian Chaco, soil-transmitted helminthiases (STH), malaria, and Chagas disease are potential infectious causes of anemia among school-aged children (SAC). Following years of preventive chemotherapy with mebendazole, the prevalence of STH among SAC living in that area is now negligible, whereas protozoan infections are still highly prevalent (81%); Hymenolepis nana is the most frequent intestinal helminth (~13%). We present results of hemoglobin (Hb) assessment and the association between parasitic infections and Hb levels of that SAC population. Overall, 511 SAC (girls:boys ratio 1:1, mean age 9.4 years [95% confidence interval {CI}: 9.3-9.5]) had Hb levels measured by using a portable Hb system HB 301+ (HemoCue1 AB; Angelhome, Sweden). The prevalence of anemia was 23% (117/511), with mean and median Hb level = 12.2 g/dL (95% CI: 12.1-12.3; range 9.2-15.4 g/dL). By multivariate analysis, H. nana infection was associated with an increased risk of anemia (odds ratio 2.9, 95% CI: 1.5-5.7, P = 0.002). Two samples (0.5%) were positive for Trypanosoma cruzi and none for Plasmodium spp. by polymerase chain reaction of the 439 children tested. Anemia is still a concern among SAC living in the Bolivian Chaco. Our findings call for a greater attention to fecal-oral emerging pathogens, such as H. nana, and highlight the importance of water, sanitation, and hygiene improvements for disadvantaged population such as those living in the Bolivian Chaco. PMID- 30298807 TI - Hepatitis B Infection among Parturient in Peri-Urban Ghana. AB - Global evidence suggests that hepatitis B viral (HBV) infection is endemic in Africa and perinatal transmission remains one of the most important modes of HBV transmission in this area. This cross-sectional survey examined the seroprevalence and knowledge of hepatitis B among pregnant women attending antenatal clinic (ANC) in a mission hospital in Ghana. Systematic sampling technique was used to recruit 196 pregnant women. The level of statistical significance was set at 0.05 alpha level. The hepatitis B prevalence estimate (hepatitis B surface antigen) was 10.2% (N = 20) and the entirety of the participants were aware of HBV infection. Majority cited media (radio) as their main source of information. Approximately 86% of the participants (N = 168) associated HBV infection with a curse and 88.8% (N = 174) indicated witches and wizards as possible causes of the infection. Those with higher level of school education had high hepatitis B knowledge score (P < 0.01). Implementation of a health education program on the route of hepatitis B transmission is required in the study setting. Also, inclusion of hepatitis B education as part of ANC activities will enable HBV-positive pregnant women to appreciate the need for hepatitis B vaccination of their newborns at birth. PMID- 30298808 TI - Individual and Spatial Risk of Dengue Virus Infection in Puerto Maldonado, Peru. AB - Dengue virus (DENV) affects more than 100 countries worldwide. Dengue virus infection has been increasing in the southern Peruvian Amazon city of Puerto Maldonado since 2000. We designed this study to describe the prevalence of past DENV infection and to evaluate risk factors. In 2012, we conducted a cross sectional serosurvey and administered a knowledge, attitudes, and practices (KAP) questionnaire to members of randomly selected households. Sera were screened for antibodies to DENV by ELISA and confirmed by plaque reduction neutralization test. We created indices for KAP (KAPi). We used SaTScan to detect clustering and created a multivariate model introducing the distance of households to potential vector and infection sources. A total of 505 participants from 307 households provided a blood sample and completed a questionnaire. Fifty-four percent of participants (95% CI: 49.6; 58.5) had neutralizing antibodies to DENV. Higher values of KAPi were positively associated with having DENV antibodies in the multivariate analysis (odds ratio [ORII]: 1.6, 95% CI: 0.6, 2.4; ORIII: 2.7, 95% CI: 1.3, 5.5; and ORIV: 2.4, 95% CI: 1.2, 5.0). Older groups had lower chances of having been exposed to DENV than younger people (OR20-30: 0.5, 95% CI: 0.2, 0.8; OR31-45: 0.5, 95% CI: 0.3, 0.9; and OR>45: 0.6, 95% CI: 0.3, 1.3). Multivariate data analysis from the 270 households with location information showed male gender to have lower risk of past DENV infection (OR: 0.6, 95% CI: 0.4, 0.9). We conclude that risk of DENV infection in Puerto Maldonado is related to gender, age of the population, and location. PMID- 30298809 TI - Alternate Anti-Leprosy Regimen for Multidrug Therapy Refractory Leprosy: A Retrospective Study from a Tertiary Care Center in North India. AB - A subset of multibacillary (MB) leprosy patients manifest with clinical "nonresponsiveness" to the fixed-duration, World Health Organization multidrug therapy MB regimen (WHO-MDT-MBR). The aim of this retrospective study was to assess the effectiveness and safety of alternate anti-leprosy therapy (ALT) in such patients. This is an analysis of patients' records, registered in the leprosy clinic of our institute over a period of 6 years (2010-2015). The criteria for inadequate response/nonresponsiveness to treatment were as follows: 1) persistent/new lesions after completing >= 12 months of WHO-MDT-MBR (isolated reactions were ruled out histopathologically) and 2) persistent positive/increasing value of the morphological index (MI) and a 2 log increase in the bacteriological index (BI) after >= 12 months of WHO-MDT-MBR. Such cases were treated with ALT consisting of minocycline, clofazimine, and ofloxacin (24 months). Of 556 patients registered during the study period, 40.3% (224) were slit-skin smear (SSS) positive and 59.7% (332) were SSS negative. Of all, 35 patients (6.3%) satisfied the criteria for clinical nonresponsiveness. Of 224 SSS positive patients, these 35 patients amounted to 15.6%. The mean BI and MI of these patients after completion of >= 12 months of WHO-MDT-MBR were 5.3 +/- 0.6 and 14 +/- 6.8%, respectively. After 6 months of treatment with ALT, MI became negative (0) in all these patients. After completion of ALT, the mean BI and MI became 1.7 +/- 0.7 and 0%, respectively (P < 0.0001). There were 16 patients with corticosteroid-dependent recurrent/chronic erythema nodosum leprosum, who had excellent response with significant reduction in the number of reactional episodes and mean dose of prednisolone required (P < 0.0001). No serious adverse effects were noted. We conclude that ALT is safe and effective in the management of MB leprosy patients who are nonresponsive to 12 months of WHO-MDT-MBR. PMID- 30298810 TI - Antibodies in Melioidosis: The Role of the Indirect Hemagglutination Assay in Evaluating Patients and Exposed Populations. AB - Melioidosis is a major neglected tropical disease with high mortality, caused by the Gram-negative bacterium Burkholderia pseudomallei (Bp). Microbiological culture remains the gold standard for diagnosis, but a simpler and more readily available test such as an antibody assay is highly desirable. In this study, we conducted a serological survey of blood donors (n = 1,060) and adult melioidosis patients (n = 200) in northeast Thailand to measure the antibody response to Bp using the indirect hemagglutination assay (IHA). We found that 38% of healthy adults (aged 17-59 years) have seropositivity (IHA titer >= 1:80). The seropositivity in healthy blood donors was associated with having a declared occupation of rice farmer and with residence in a nonurban area, but not with gender or age. In the melioidosis cohort, the seropositivity rate was higher in adult patients aged between 18 and 45 years (90%, 37/41) compared with those aged >= 45 years (68%, 108/159, P = 0.004). The seropositivity rate was significantly higher in people with diabetes (P = 0.008). Seropositivity was associated with decreased mortality on univariable analysis (P = 0.005), but not on multivariable analysis when adjusted for age, diabetes status, preexisting renal disease, and neutrophil count. This study confirms the presence of high background antibodies in an endemic region and demonstrates the limitations of using IHA during acute melioidosis in this population. PMID- 30298811 TI - Enteric Fever in Cambodia: Community Perceptions and Practices Concerning Disease Transmission and Treatment. AB - Enteric fever is a systemic bacterial infection in humans that is endemic in Cambodia and for which antibiotic resistance is increasingly reported. To guide public health programs, this qualitative study sought to explore community perceptions on transmission and treatment. Participant observation was carried out in hospital settings, pharmacies, and at a community level in Phnom Penh. In depth interviews 39 and one focus group discussion were carried out with blood culture-confirmed enteric fever patients and purposively selected key informants. Informants were theoretically sampled based on initial themes identified using abductive analysis. Nvivo 11 was used for thematic coding. An urgent need to address health literacy concerning the transmission of enteric fever was identified, as lay informants did not link the disease and its symptoms to bacterial contamination of foods and drinks but rather to foods considered "bad" following humoral illness interpretations. As a result, lay informants considered recurrence of enteric fever preventable with appropriate dietary restrictions and Khmer traditional medicines. This study also reveals pluralistic health-care seeking behavior. For initial and mild symptoms, patients preferred home treatment or traditional healing practices; limited household finances delayed treatment seeking. When symptoms persisted, patients first visited drug outlets or private practitioners, where they received a mix of nonessential medicines and one or more antibiotics often without prescription or confirmation of diagnosis. Inappropriate use of antibiotics was common and was related to diagnostic uncertainty and limited finances, factors which should be addressed during future efforts to improve the uptake of appropriate diagnostics and treatment of enteric fever. PMID- 30298812 TI - Visceral Leishmaniasis in the Muzaffapur Demographic Surveillance Site: A Spatiotemporal Analysis. AB - In the Indian subcontinent, visceral leishmaniasis (VL) has a strongly clustered distribution. The "index case approach" is promoted both for active case finding and indoor residual spraying (IRS). Uncertainty exists about the optimal radius. Buffer zones of 50-75 m around incident cases have been suggested for active case finding, for IRS the recommendation is to cover a radius of 500 m. Our aim was to establish optimal target areas both for IRS and for (re)active case finding. We plotted incident VL cases on a map per 6-month period (January-June or July December) and drew buffers of 0 (same household), 50, 75, 100, 200, 300, 400, and 500 m around these cases. We then recorded total population and numbers of VL cases diagnosed over the next 6-month period in each of these buffers and beyond. We calculated incidence rate ratios (IRRs) using the population at more than 500 m from any case as reference category. There was a very strong degree of spatial clustering of VL with IRRs ranging from 45.2 (23.8-85.6) for those living in the same households to 14.6 (10.1-21.2) for those living within 75 m of a case diagnosed, during the previous period. Up to 500 m the IRR was still five times higher than that of the reference category. Our findings corroborate the rationale of screening not just household contacts but also those living within a perimeter of 50-75 m from an index case. For IRS, covering a perimeter of 500 m, appears to be a rational choice. PMID- 30298813 TI - Leptospirosis in French Historical Medical Literature: Weil's Disease or Kelsch's Disease? AB - Early names for leptospirosis often indicate occupational or environmental exposure. Leptospirosis is hard to identify in the tropical setting because of co circulating diseases. This is not the case in the temperate setting, such as Europe, where the few differential diagnoses at the time are malaria, typhoid, and viral hepatitis. Leptospirosis presumably caused community epidemics in Europe before 1900 and military epidemiologists carefully documented outbreaks in "constrained settings." Achille Kelsch (1841-1911) synthesized available military data and epidemiological perspectives to define "epidemic jaundice" as a nosological continuum, caused by an infectious agent found in muds and water. He viewed Weil's disease as being only one form of that now well-identified disease continuum. The causative pathogen and epidemiological determinants were identified years later. The role of soils and muds as intermediate reservoirs, as suggested by Kelsch, deserves further investigation. PMID- 30298814 TI - Aboard the Good Ship Verona. PMID- 30298817 TI - Anti-inflammatory effects of olive-derived hydroxytyrosol on lipopolysaccharide induced inflammation in RAW264.7 cells. AB - The control of inflammation, which arises from complex biological responses to harmful stimuli, is an important determinant of both clinical outcomes and patient comfort. However, the side effects of many current therapies such as non steroidal anti-inflammatory drugs mean that new safe treatments are required. We previously reported that 12.5 MUg/ml hydroxytyrosol (HT) suppressed gene expression of the inducible nitric oxide (NO) synthase (iNOS) isoform and NO production, in mouse peritoneal macrophages treated with lipopolysaccharide (LPS), where nuclear factor-kappaB (NF-kappaB) gene expression was not altered. The present study evaluated the anti-inflammatory effects of various concentrations of HT in LPS-induced RAW264.7 mouse macrophages. HT suppressed NF kappaB signaling and downregulated LPS-mediated expression of iNOS, cyclooxygenase-2, tumor necrosis factor alpha, and interleukin-1beta at 12.5 MUg/ml, resulting in reduced production of NO and prostaglandin E2. At lower concentrations, HT seemed to act via another signaling pathway to regulate the inflammatory response. In contrast, HT did not suppress LPS-induced expression of phosphorylated p44/42 mitogen-activated protein kinase. This study showed that HT had anti-inflammatory effects on LPS-stimulated RAW264.7 cells. HT is already available as a nutritional supplement and no toxic effects have been reported. Hence, HT represents a potential novel anti-inflammatory agent.

PMID- 30298816 TI - Spatiotemporal mosaic self-patterning of pluripotent stem cells using CRISPR interference. AB - Morphogenesis involves interactions of asymmetric cell populations to form complex multicellular patterns and structures comprised of distinct cell types. However, current methods to model morphogenic events lack control over cell-type co-emergence and offer little capability to selectively perturb specific cell subpopulations. Our in vitro system interrogates cell-cell interactions and multicellular organization within human induced pluripotent stem cell (hiPSC) colonies. We examined effects of induced mosaic knockdown of molecular regulators of cortical tension (ROCK1) and cell-cell adhesion (CDH1) with CRISPR interference. Mosaic knockdown of ROCK1 or CDH1 resulted in differential patterning within hiPSC colonies due to cellular self-organization, while retaining an epithelial pluripotent phenotype. Knockdown induction stimulates a transient wave of differential gene expression within the mixed populations that stabilized in coordination with observed self-organization. Mosaic patterning enables genetic interrogation of emergent multicellular properties, which can facilitate better understanding of the molecular pathways that regulate symmetry breaking during morphogenesis. PMID- 30298815 TI - Ancient mechanisms for the evolution of the bicoid homeodomain's function in fly development. AB - The ancient mechanisms that caused developmental gene regulatory networks to diversify among distantly related taxa are not well understood. Here we use ancestral protein reconstruction, biochemical experiments, and developmental assays of transgenic animals carrying reconstructed ancestral genes to investigate how the transcription factor Bicoid (Bcd) evolved its central role in anterior-posterior patterning in flies. We show that most of Bcd's derived functions are attributable to evolutionary changes within its homeodomain (HD) during a phylogenetic interval >140 million years ago. A single substitution from this period (Q50K) accounts almost entirely for the evolution of Bcd's derived DNA specificity in vitro. In transgenic embryos expressing the reconstructed ancestral HD, however, Q50K confers activation of only a few of Bcd's transcriptional targets and yields a very partial rescue of anterior development. Adding a second historical substitution (M54R) confers regulation of additional Bcd targets and further rescues anterior development. These results indicate that two epistatically interacting mutations played a major role in the evolution of Bcd's controlling regulatory role in early development. They also show how ancestral sequence reconstruction can be combined with in vivo characterization of transgenic animals to illuminate the historical mechanisms of developmental evolution.

AB - Ovarian reserve in cattle can be predicted by an indicator, the antral follicle count (AFC), which is easily determined via ovarian ultrasonography. However, the repeatability of AFC measurements in the same individual taken approximately 1 year apart after first parity remains unclear. This study, thus, aimed to clarify the between-lactation repeatability of AFC after first parity in dairy cows. We measured the AFC of the same individual cows consecutively across both first and second parity, both second and third parity, and both third and fourth parity in 31, 37, and 26 heads, respectively. The values of the intraclass correlation coefficients (ICC) for the AFCs in first-second and second-third parity cows were more than 0.8, and the value of the ICC for the AFCs in third-fourth parity cows was significantly lower than that in first-second parity cows (P = 0.01). Subsequently, based on the average number of AFCs measured at some points from first to third parity, we classified the cows into three tertiles: < 11 (low), 11 15 (intermediate), and >= 15 (high). We then compared the reproductive performance of the first through third parity cows among the groups. The hazards of pregnancy by 200 days postpartum were higher in the high group than in the other groups (P < 0.05). Our findings demonstrate that between-lactation repeatability of AFC from first through third parity in dairy cows is very high, and that cows with an AFC of >= 15 have a better reproductive performance than cows with a low AFC. PMID- 30298824 TI - Involvement of interferon-tau in the induction of apoptotic, pyroptotic, and autophagic cell death-related signaling pathways in the bovine uterine endometrium during early pregnancy. AB - Interferon-tau (IFNT), a type I interferon (IFN), is known as pregnancy recognition signaling molecule secreted from the ruminant conceptus during the preimplantation period. Type I IFNs, such as IFN-alpha and IFN-beta, are known to activate cell-death pathways as well as induce apoptosis. In cows, induction of apoptosis with DNA fragmentation is induced by IFNT in cultured bovine endometrial epithelial cells. However, the status of cell-death pathways in the bovine endometrium during the preimplantation period still remains unclear. In the present study, we investigated the different cell-death pathways, including apoptosis, pyroptosis, and autophagy, in uterine tissue obtained from pregnant cows and in vitro cultured endometrial epithelial cells with IFNT stimulation. The expression of CASP7, 8, and FADD (apoptosis-related genes) was significantly higher in pregnant day 18 uterine tissue in comparison to non-pregnant day 18 tissue. The expression of CASP4, 11, and NLRP3 (pyroptosis-related genes) was significantly higher in the pregnant uterus in comparison to non-pregnant uterus. In contrast, autophagy-related genes were not affected by pregnancy. We also investigated the effect of IFNT on the expression of cell-death pathway-related genes, as well as DNA fragmentation in cultured endometrial epithelial cells. Similar to its effects in pregnant uterine tissue, IFNT affected the increase of apoptosis-related (CASP8) and pyroptosis-related genes (CASP11), but did not affect autophagy-related gene expression. IFNT also increased gammaH2AX-positive cells, which is a marker of DNA fragmentation. These results suggest that apoptosis- and pyroptosis-related genes are induced by IFNT in the pregnant bovine endometrial epithelial cells. PMID- 30298825 TI - The roles of kisspeptin in the mechanism underlying reproductive functions in mammals. AB - Kisspeptin, identified as a natural ligand of GPR54 in 2001, is now considered as a master regulator of puberty and subsequent reproductive functions in mammals. Our previous studies using Kiss1 knockout (KO) rats clearly demonstrated the indispensable role of kisspeptin in gonadotropin-releasing hormone (GnRH)/gonadotropin secretion. In addition, behavioral analyses of Kiss1 KO rats revealed an organizational effect of kisspeptin on neural circuits controlling sexual behaviors. Our studies using transgenic mice carrying a region-specific Kiss1 enhancer-driven reporter gene provided a clue as to the mechanism by which estrogen regulates Kiss1 expression in hypothalamic kisspeptin neurons. Analyses of Kiss1 expression and gonadotropin secretion during the pubertal transition shed light on the mechanism triggering GnRH/gonadotropin secretion at the onset of puberty in rats. Here, we summarize data obtained from the aforementioned studies and revisit the physiological roles of kisspeptin in the mechanism underlying reproductive functions in mammals. PMID- 30298826 TI - The Effect of Improving Oral Hygiene through Professional Oral Care to Reduce the Incidence of Pneumonia Post-esophagectomy in Esophageal Cancer. AB - Radical esophagectomy for thoracic esophageal cancer is invasive and frequently results in postoperative pulmonary complications. Postoperative pneumonia is the most common such complication and affects hospital mortality and survival rates. Oral care has been very effective in reducing pneumonia. In Japan, preoperative professional oral care is highly recommended. However, there are few studies on the effect of preoperative improvements in oral hygiene as a result of intervention on the incidence of postoperative pneumonia. The primary end-point of this retrospective study was the incidence of postoperative pneumonia after radical esophagectomy. The oral health levels of 46 patients were individually categorized, and then patients were grouped according to whether they maintained or improved their oral hygiene. At the first dental examination, oral health levels were classified as good in 22 patients and bad in 24. Of the 46 patients studied, 39 patients maintained or improved their oral hygiene (good control group), whereas 7 showed no improvement (bad control group). Postoperative pneumonia occurred in eight patients: four in the good control group and four in the bad control group. Statistical analysis with postoperative pneumonia as a dependent variable showed a significant effect of oral hygiene improvement on the incidence of pneumonia. Logistic regression analysis with this factor as an independent variable demonstrated that the risk of postoperative pneumonia was reduced in the good control group (OR 0.086, 95% CI 0.014-0.529). Therefore, preoperative professional oral care may improve oral hygiene and oral health, which may in turn reduce the incidence of postoperative pneumonia. PMID- 30298827 TI - Design, Synthesis, and Screening of 5-Aryl-3-(2-(pyrrolyl)thiophenyl)-1,2,4 oxadiazoles as Potential Antitumor Molecules on Breast Cancer MCF-7 Cell Line. AB - The work reported the design and cytotoxic screening of synthetic small molecules: carbonitriles 3a-c, carboximidamides 4a-c, and oxadiazoles 5-19 as antitumor molecules. Molecules 4c, 9, 12, and 14 show promising cytotoxicity profiles against two cell lines higher than prodigiosin (PG). The results of topoisomerase enzyme inhibition assay show that carboximidamide 4c and oxadiazole 14 display potent inhibitory activity in nano-molar concentration higher than PG. In addition, carboximidamide 4c and oxadiazoles 9, 12, and 14 exhibit antiproliferative activities over MCF-7 cells by cell cycle arrest at G1 phase and apoptosis inducing activity by increasing cell population percentages at pre G1 and G2/M phases as shown by DNA-flow cytometry assay and annexin V analysis. Moreover, measurement of p53 and cell death mediators, show that carboximidamide 4c and oxadiazoles 9, 12, and 14 significantly up-regulate p53, Puma and Bax/Bcl 2 ratio levels. Subsequently, pro-apoptotic activities are confirmed by active caspase 3/7 percentages green fluorescence assay. PMID- 30298828 TI - Advantage of parenteral nutrition for diarrheic calves. AB - This study assessed the advantages of dextrose and amino acid mixture solution as parenteral nutrition (PN) therapy for diarrheic calves. Thirty diarrheic calves were randomly assigned to receive PN (PN group, n=15) or only dextrose solution (Dex group, n=15). The treatment period for the PN group (4.0 days; min-max, 2-10 days) was significantly shorter than that for the Dex group (6.0 days; min-max, 3 21 days) (P<0.01). The PN therapy tended to improve plasma diamine oxidase activity compared with traditional therapy. One potential association between PN therapy and shortened treatment period may be the repair of damaged intestinal villi. Although our proposal has limitations, PN therapy suggested the potential for new treatment of diarrheic calves. PMID- 30298829 TI - LH and testosterone secretions in response to GnRH challenge in pubertal Japanese Black beef bulls with normal and abnormal semen. AB - Plasma luteinizing hormone (LH) and testosterone concentrations were examined in Japanese Black beef bulls with normal and abnormal semen in response to gonadotropin releasing hormone (GnRH) challenge at the start (10 months) and completion (20 months) of puberty. Bulls with normal semen had higher testosterone concentrations after GnRH treatment at 20 months than they did at 10 months, while LH concentrations did not differ between the two age groups. LH and testosterone concentrations were not different between bulls with normal and abnormal semen at 20 months. Thus, testosterone secretions in response to the GnRH challenge were higher for bulls with normal semen at pubertal completion compared to bulls at the start of puberty, but responsiveness of LH to GnRH and of testosterone to the LH increment was not altered in bulls with abnormal semen. PMID- 30298830 TI - Development of a PCR assay for detection and differentiation of Muscovy duck and goose parvoviruses based on NS gene characterization. AB - Muscovy duck parvovirus (MDPV) and goose parvovirus (GPV) have both been found to cause high mortality and morbidity in Muscovy ducklings. Specific detection is often rife with false positives due to high identity at the genomic nucleotide level and antigenic similarity between MDPVs and GPVs. In this study, significantly variable regions were found, via NS comparison, between MDPV and GPV NS genes; however, NS genes were conserved within the MDPV and GPV groups. A polymerase chain reaction (PCR) assay for detecting and differentiating MDPVs and GPVs was developed with more specificity based on the NS gene characterization. The assay detected as low as 103 DNA copies of both the MDPV and GPV strains, along with 549 separate base pairs (bp). No bands of the same size from other duck pathogens, including duck circovirus, duck enteritis virus, egg drop syndrome virus, duck-origin goose hemorrhagic polyomavirus, Escherichia coli, Salmonella, Riemerella anatipestifer and Pasteurella multocida were amplified. This indicates that this method for performing PCR provides a useful and reliable alternative tool for more precise differentiation of MDPV and GPV infection in clinical samples. PMID- 30298831 TI - Microdiscectomy and Foraminotomy in Cervical Spondylotic Myelopathy and Radiculopathy. AB - This study was to assess the efficacy of microdiscectomy, cage fixation, and right tranuncal foramintomy for the patients suffering from right radiulo myelopathy. Anterior cervical foraminotomy was reported to be an effective option for the treatment of cervical degenerative radiculopathy but with the problem of recurrence. Since Hakuba reported the method of trans-unco-discal approach in 1976, it was designed as keyhole foraminotomy which was called transuncal approach, transpedicular approach or transvertebral approach. In the anterior approach, we usually use the right-sided approach because most of us are right handed surgeons. We retrospectively investigated our patients who had the right foraminal stenosis causing radiculopathy and were treated with microdiscectomy, cage fixation, and right keyhole transuncal foraminotomy. Since 2011, 23 patients were treated with the manner. All of the 23 patients who had central canal stenosis and among the 23 patients, 8 patients showed only right radiculopathy and 15 patients showed radiculo-myelopathy. In all patients, the radiculopathy disappeared or significantly improved without any complications postoperatively. The average of VAS scores was 7.6 +/- 2.2 in preoperative state, 2.8 +/- 2.2 at discharge, and 1.1 +/- 1.6 in 1 month after surgery. The average of follow-up time was 38.3 months and they had no recurrence of radiculopathy. We showed that this manner is effective and one option for the combined disease of right foraminal and canal stenosis and we believe that this manner is not complex and safe if we can understand the anatomy.

AB - Flow diverters (FDs) have been developed for intracranial aneurysms difficult to treat with conventional endovascular therapy and surgical clipping. We reviewed 94 patients with 100 large or giant unruptured internal carotid artery (ICA) aneurysms treated with Pipeline embolization device (PED) embolization from December 2012 to June 2017 at Juntendo University Hospital. The patients' mean age was 63.4 years (range, 19-88), and there were 90 women 89.4%. Aneurysm locations were: C4 (45), C3 (4), and C2 (51) in ICA segments. Mean aneurysm size and neck width were 16.9 +/- 6.8 mm and 8.3 +/- 4.4 mm, respectively, in 40 symptomatic and 60 asymptomatic aneurysms. Follow-up catheter angiographies of 85 patients with 90 aneurysms showed no filling in 62 aneurysms (68.9%), entry remnant in 16 (17.8%), subtotal filling in 11 (12.2), and total filling in 1 (1.1%) with a mean follow-up of 10.2 +/- 5.6 months. In-stent stenosis occurred in 1 patient and parent artery occlusion in 2 during follow-up. Hemorrhagic complications occurred in 4 (4.3%): delayed aneurysm rupture (2) and intraparenchymal hemorrhage (2). Ischemic complications with neurological symptoms occurred in 2 (2.1%): very delayed device occlusion (1) and intraprocedural distal embolism (1). Eighteen patients (45%) showed improvement in pre-existing cranial nerve dysfunction because of the aneurysm's mass effect, 3 patients (7.5%) worsened. One patient died of systemic organ failure unassociated with the procedure. Morbidity and mortality rates were 4.3% and 1.1%, respectively. PED embolization for unruptured large and giant ICA aneurysms is safe and efficacious. Physicians should be observant of characteristic risks associated with FD therapy. PMID- 30298834 TI - Use of Pulmonary Inhalants Remains Remarkably High After Atrial Septal Defect Closure. AB - BACKGROUND: Post-repair atrial septal defects (ASD) patients are frequently discharged from follow-up, but the extent of pulmonary symptoms long-term post repair is unknown. Methods and Results: The national CONgenital CORvitia registry was linked to the national Drug Registry to investigate all ambulatory-dispensed pulmonary inhalants for 2006-2014. ASD patients were compared with age- and sex matched referents from the general population. A total of 1,959 adult patients (age 42+/-17 years; 66% female; 1,223 [62%] repaired) were included. Compared with the referents, ASD patients had more inhalant use, even at long-term post repair follow-up (OR=1.81 [95% CI 1.62-2.03]; P<0.001). CONCLUSIONS: ASD patients had 2-fold higher inhalant use compared with referents even at long-term post repair follow-up, suggesting persistent pulmonary functional impairment.

PMID- 30298835 TI - Effect of Hypertension on Aortic Artery Disease-Related Mortality - 3.8-Year Nationwide Community-Based Prospective Cohort Study. AB - BACKGROUND: Aortic artery disease (AAD), such as aortic dissection or aortic aneurysm rupture, is fatal, with an extremely high mortality. Because of its low incidence, the risk for the development of AAD has not yet been elucidated. Hypertension (HT) is an established risk factor for cardiovascular disease, but there has been no prospective study on the effect of HT on AAD-related mortality. Methods and Results: We used a nationwide database of 276,197 subjects (aged 40 75 years) who participated in the annual "Specific Health Check and Guidance in Japan" from 2008 to 2010. There were 80 AAD-related deaths during the follow-up period of 1,049,549 person-years. On multivariate Cox proportional hazard regression, HT was an independent risk factor for AAD-related death in apparently healthy subjects. On receiver operating characteristics curve analysis for AAD related death, abnormal systolic and diastolic blood pressure (SBP and DBP) were 130 mmHg and 82 mmHg, respectively. The prediction capacity was significantly improved by the addition of SBP to confounding risk factors. Notably, further improvement of the C index was observed by addition of DBP to the model with SBP. CONCLUSIONS: This is the first report to prospectively show that HT is a risk factor for AAD-related death. Both SBP and DBP are of critical importance in the primary prevention of AAD-related death in apparently healthy subjects. PMID- 30298837 TI - [TRPV4 regulates vascular endothelial permeability during colonic inflammation in dextran sulphate sodium-induced murine colitis]. AB - The transient receptor potential vanilloid 4 (TRPV4) is a nonselective cation channel involved in physical sensing in various tissue types. The present study aimed to elucidate the function and expression of TRPV4 in colonic vascular endothelial cells during dextran sulphate sodium (DSS)-induced colitis. The role of TRPV4 in the progression of colonic inflammation was examined in the 2% DSS induced murine colitis model using immunohistochemical analysis, Western blotting, and Evans blue dye extrusion assay. DSS-induced colitis was significantly attenuated in TRPV4-deficient (TRPV4 KO) mice when compared to wild type mice. Repeated intrarectal administration of GSK1016790A, a TRPV4 agonist, exacerbated the severity of DSS-induced colitis. Bone marrow transfer experiments demonstrated a dominant role of TRPV4 in non-haematopoietic cells for DSS-induced colitis. DSS treatment upregulated TRPV4 expression in the vascular endothelia of colonic mucosa and submucosa. DSS treatment increased vascular permeability, which was abolished in TRPV4 KO mice. The DSS-induced increase in vascular permeability was further enhanced by intravenous administration of GSK1016790A, which was abrogated by a TRPV4 antagonist RN1734. TRPV4 was co-localized with vascular endothelial (VE)-cadherin, and VE-cadherin expression was decreased by repeated intravenous administration of GSK1016790A during colitis. Furthermore, TRPV4 activation by GSK106790A decreased VE-cadherin expression in mouse aortic endothelial cells exposed to TNF-alpha. These findings indicate that TRPV4 upregulation in vascular endothelial cells contributes to the progression of colonic inflammation via the activation of vascular permeability. Thus, TRPV4 is an attractive target for the treatment of inflammatory bowel diseases. PMID- 30298838 TI - [Recent progress in the research of Eosinophilic GastroIntestinal Diseases (EGIDs)]. AB - Eosinophilic esophagitis (EoE) and eosinophilic gastroenteritis (EGE), which are included in eosinophilic gastrointestinal disorders (EGIDs), are allergic gastrointestinal diseases mainly caused by food allergens, which features dense infiltration of eosinophiles in the gastrointestinal mucosa. A possible mechanism of these diseases are Th2 type allergic reactions, including IL-5, IL-13, and IL 15, thymic stromal protein (TSLP), and eotaxin 3, which are considered to have important roles. The number of patients with EoE is rapidly increasing in both Western and Asian countries. In Japan, a research group of the Ministry of Health, Labor and Welfare has announced recommendations for the diagnosis and management of EoE and EGE in 2015. For a diagnosis of EoE, endoscopic abnormalities and histological confirmation of dense eosinophile infiltration in the esophageal epithelial layer are important, in addition to identifying dysphagia symptoms. As for eosinophilic gastroenteritis, blood test findings are more useful and the role of an endoscopic examination is reduced. Glucocorticoid administration is standard treatment for these diseases, while proton pump inhibitors are frequently effective for EoE. As for EoE, on the one hand, a variety of studies have been performed and new findings collected. On the other hand, information concerning EGE is limited and additional evidence is needed to establish effective treatment options. PMID- 30298839 TI - [The involvement of NOX1/NADPH oxidase in the development of non-alcoholic steatohepatitis]. AB - Reactive oxygen species (ROS) are known to play a critical role in the development of non-alcoholic steatohepatitis (NASH). To clarify the source of ROS, we examined the expression of superoxide-generating NADPH oxidase isoforms in the liver of high-fat and high-cholesterol (HFC) diet-fed mice. The mRNA expression of NOX1 was significantly elevated in mice on HFC diet for 8 weeks. Increased levels of serum alanine aminotransferase and hepatic cleaved caspase-3 in HFC diet-fed wild-type mice (WT) were significantly ameliorated in mice deficient in Nox1 (Nox1-KO). Increased nitrotyrosine adduct formation, a marker of peroxynitrite-induced injury, was observed in hepatic sinusoids of WT, which was significantly suppressed in NOX1-KO. NOX1 mRNA was mainly expressed in liver sinusoidal endothelial cells (LSECs), and it was significantly up-regulated in primary cultured LSECs treated with palmitic acid (PA). The production of nitric oxide by LSECs and LSECs-dependent relaxation of hepatic stellate cells were significantly attenuated by PA treatment. In contrast, these effects of PA were not observed in cells isolated from Nox1-KO. Taken together, the up-regulation of NOX1 in LSECs may elicit peroxynitrite-mediated cellular injury and impair hepatic microcirculation through reduced bioavailability of nitric oxide. ROS derived from NOX1 may therefore constitute a critical component in the development of NASH. PMID- 30298840 TI - [Gut microbiota and nonalcoholic steatohepatitis]. AB - Nonalcoholic fatty liver disease (NAFLD), especially nonalcoholic steatohepatitis (NASH), is a disease that may lead to liver cirrhosis or hepatocellular carcinoma. The number of patients is increasing steadily and the pathology is diverse. Effective treatment is still mainly focused on diet and exercise therapy. With the advent of the next-generation sequencer, the intestinal flora in NAFLD/NASH is being elucidated. We believe that elevation of endotoxin in the blood caused by intestinal bacterial dysbiosis caused by intestinal permeability enhancement is important for NASH pathology and control of intestinal permeability enhancement has a new possibility for treatment of NAFLD/NASH. PMID- 30298841 TI - [Neurological mechanism and therapeutic strategy for posttraumatic stress disorders]. AB - Posttraumatic stress disorder (PTSD) is most often induced by traumatic events and serious public health problems. PTSD is characterized by excessive response to contextual memory and impaired fear extinction and also associated with mild cognitive impairment, attention and learning deficits. Clinical and animal studies suggest that increased susceptibility of emotion- and fear-related neuronal circuits, including those in the amygdala, prefrontal cortex and hippocampus, contributes to development and retention of PTSD symptoms. However, mechanisms underlying this susceptibility to fear are not known and the useful therapeutic approaches are limited. Recently, there have been reports that omega3 LCPUFA supplementation can prevent development of PTSD and significantly ameliorate symptoms in patients with PTSD after accidental injury such as motor vehicle accidents and natural calamities. Importantly, Fabp7 null mice exhibit enhancement of fear memory consolidation and anxiety-related behaviors that resemble PTSD-like behaviors in humans. In this review, we focused behavioral phenotype of PTSD in Fabp3 null mice. The Fabp3 null mice exhibit cognitive deficits, hyperlocomotion and impaired fear extinction, and thus show PTSD-like behaviors. Chronic administration of ramelteon, a melatonin receptor agonist, improved all PTSD-like behaviors tested in Fabp3-/- mice. Relevant to mechanisms underlying impaired fear extinction, we observed that Ca2+/calmodulin-dependent protein kinase II (CaMKII) autophosphorylation increases in the basolateral amygdala (BLA) but remained unchanges in the hippocampus of Fabp3-/- mice. Likewise, the number of c-Fos positive neurons in BLA significantly increased after exposure to contextual fear conditions. Finally, chronic ramelteon administration restored abnormal c-Fos expression and CaMKII autophosphorylation in the BLA of Fabp3-/- mice. Taken together, Fabp3-/- mice show PTSD-like behaviors, and ramelteon is an attractive candidate for PTSD therapeutics in human. PMID- 30298842 TI - [Current progress of research and use of microminipigs in drug development]. AB - The use of minipigs has been increasing in the areas of pharmacology researches and drug development. The microminipig developed by Fuji Micra Inc. (Shizuoka, Japan) inherits characteristics of other pig strains showing several similarities to humans in anatomy, physiology, omnivorousness and diurnal, but at the same time has several advantages over other pig strains because of its small size which allows easy keeping, handling and dosing, and saving of test substances. The microminipig weighs about 10 kg at the age of 6 months. Canine cages can be used to keep the animal. Swine leukocyte antigens (SLA) are defined in each individual animal which is useful for testing immunological reactions. As there are many similarities in metabolic enzymes and transporters to those in humans, the microminipig is a powerful animal model for toxicokinetic studies. Unfortunately as in other minipigs the microminipig is not appropriate for embryo fetal development studies of antibody drugs due to its poor placental transfer, but can be used for other reproductive and developmental studies. Repeat dose toxicity, safety pharmacology, immunotoxicity and local tolerance studies should be also other arenas of this animal model.

PMID- 30298845 TI - Principles of precision medicine and its application in toxicology. AB - Precision medicine is an approach to developing drugs that focuses on employing biomarkers to stratify patients in clinical trials with the goal of improving efficacy and/or safety outcomes, ultimately increasing the odds of clinical success and drug approval. Precision medicine is an important tool for toxicologists to utilize, because its principles can be used to decide whether to pursue a drug target, to understand interindividual differences in response to drugs in both nonclinical and clinical settings, to aid in selecting doses that optimize efficacy or reduce adverse events, and to facilitate understanding of a drug's mode-of-action. Nonclinical models such as the mouse and non-human primate can be used to understand genetic variation and its potential translation to humans, and are available for toxicologists to employ in advance of drugs moving into clinical development. Understanding interindividual differences in response to drugs and how these differences can influence the drug's risk-benefit profile and lead to the identification of biomarkers that enhance patient efficacy and safety is of critical importance for toxicologists today, and in the future, as the fields of pharmacogenomics and genetics continue to advance. PMID- 30298846 TI - Inhibition of L-type calcium channels by Bisphenol A in rat aorta smooth muscle. AB - Bisphenol A (BPA) is an endocrine disrupting chemical used on a wide range in industry. This compound has been used in the production of polycarbonate plastics and epoxy resins. For this reason and their global use, BPA is one of the most common environmental chemicals to which humans are exposed. This exposure can cause several adverse health outcomes, including at the cardiovascular level. The regulation of ion channels in vascular smooth muscle is pivotal and important for vasoreactivity, and changes in their flux can be involved in the pathophysiology of some cardiovascular diseases. This study aims to analyse in rat aorta whether the vasorelaxant effect of BPA is mediated by L-type Ca2+ channels inhibition. Using male Wistar rat aorta artery rings in the organ bath we analysed the contractility, and to study the activity of calcium current in A7r5 cells we used the whole cell configuration of Patch Clamp technique. Regarding the contractility experiences we observed that in both NA and KCl contraction, BPA caused a rapid and concentration-dependent relaxation. The electrophysiology experiments showed that BPA inhibited the basal and BAY K8644-stimulated whole cell L-type Ca2+ channel (W-CLTCC) currents, indicating that this drug blocks the L-type Ca2+ channels. Our results suggest that BPA inhibits the W-CLTCC, leading to the relaxation of vascular smooth muscle. PMID- 30298847 TI - Comparative study for carcinogenicity of 7 different multi-wall carbon nanotubes with different physicochemical characteristics by a single intraperitoneal injection in male Fischer 344 rats. AB - The present study comparatively examined carcinogenicity of 7 different multi wall carbon nanotubes (MWCNTs) with different physicochemical characteristics. Physicochemical characteristics of MWCNTs (referred to as M-, N-, WL-, SD1-, WS-, SD2- and T-CNTs in the present study) were determined using scanning electron and light microscopes and a collision type inductively coupled plasma mass spectrometer. Male Fischer 344 rats (10 weeks old, 15 animals per group) were administered MWCNTs at a single intraperitoneal dose of 1 mg/kg body weight, and sacrificed up to 52 weeks after the commencement. Fibers of M-, N-, WL- and SD1 CNTs were straight and acicular in shape, and contained few agglomerates. They were relatively long (38-59% of fibers were longer than 5 MUm) and thick (33% to more than 70% of fibers were thicker than 60 nm). All of these 4 MWCNTs induced mesotheliomas at absolute incidences of 100%. Fibers of WS-, SD2- and T-CNTs were curled and tightly tangled to form frequent agglomerates. They were relatively short and thin (more than 90% of measured fibers were thinner than 50 nm). WS- CNT did not induce mesothelioma, and only one of 15 rat given SD2- or T-CNT developed tumor. Any correlations existed between the metal content and neither the size or form of fibers, nor the carcinogenicity. It is thus indicated that the physicochemical characteristics of MWCNTs are critical for their carcinogenicity. The straight and acicular shape without frequent agglomerates, and the relatively long and thick size, but not the iron content, may be critical factors. The present data can contribute to the risk management, practical use and social acceptance of MWCNTs. PMID- 30298848 TI - Plasma 2-hydroxyglutarate, a promising prognostic biomarker candidate for skeletal muscle injury in Fischer 344 rats. AB - Previously, we have demonstrated the potential of plasma 2-hydroxyglutarate (2HG) as an easily detectable biomarker for skeletal muscle injury in rats. Here, we examined whether plasma 2HG was superior to conventional skeletal muscle damage biomarkers, including aspartate aminotransferase (AST), creatine kinase (CK), and skeletal muscle-type CK isoenzyme (CK-MM) levels, in rats. Skeletal muscle injury was induced in 4- or 9-week-old male Fischer 344 rats by cerivastatin (CER) or tetramethyl-p-phenylenediamine (TMPD) administration. Plasma 2HG levels were measured on days 4, 8, and 11 (CER group) and at 6 and 24 hr post-administration (TMPD group). Plasma AST, CK, and CK-MM activities and histopathological changes in the rectus femoris muscle were evaluated at the study endpoints. In the CER group, AST, CK, and CK-MM increased in 4- and 9-week-old rats, whereas increases in CK (4- and 9-week-old rats) and CK-MM (4-week-old rats) were not obvious in the TMPD group. In both 4- and 9-week-old rats, plasma 2HG increased on day 8 and at 24 hr post-administration in the CER and TMPD groups, respectively. Histopathological analysis revealed myofiber vacuolation and necrosis in both groups. The histopathological damage to the rectus femoris muscle was more severe in the CER than in the TMPD group. Increased plasma 2HG was associated with CER- and TMPD-induced skeletal muscle injuries in rats and was not affected by age differences or repeated blood collection. The results suggest that plasma 2HG is superior to CK and CK-MM as a biomarker for mild skeletal muscle injury. PMID- 30298850 TI - One-Year Follow-up After Tetralogy of Fallot Total Repair Preserving Pulmonary Valve and Avoiding Right Ventriculotomy. AB - BACKGROUND: We reviewed our revised surgical strategy for tetralogy of Fallot (TOF) total correction to minimize early exposure to significant pulmonary regurgitation (PR) and to avoid right ventriculotomy (RV-tomy). Methods and Results: Since February 2016, we have tried to preserve, first, pulmonary valve (PV) function to minimize PR by extensive commissurotomy with annulus saving; and second, RV infundibular function by avoiding RV-tomy. With this strategy, we performed total correction for 50 consecutive patients with TOF until May 2018. We reviewed the early outcomes of 27 of 50 patients who received follow-up for >=3 months. Mean patient age at operation was 10.2+/-5.0 months, and mean body weight was 8.8+/-1.2 kg. The preoperative pressure gradient at the RV outflow tract and the PV z-score were improved at most recent echocardiography from 82.0+/-7.1 to 26.8+/-6.4 mmHg, and from -2.35+/-0.49 to -0.55+/-0.54, respectively, during 11.1+/-1.6 months of follow-up after operation. One patient required re-intervention for residual pulmonary stenosis. Twenty-two patients had less than moderate PR (none, 1; trivial, 8; mild, 13), and 5 patients had moderate PR. There was no free or severe PR. CONCLUSIONS: At 1-year follow-up, the patients who underwent total TOF correction with our revised surgical strategy had acceptable results in terms of PV function. The preserved PV had a tendency to grow on short-term follow-up. PMID- 30298849 TI - Differential impacts of mineralocorticoid receptor antagonist potassium canrenoate on liver and renal changes in high fat diet-mediated early hepatocarcinogenesis model rats. AB - Mineralocorticoid receptor (MR)/NADPH oxidase (NOX) signaling is involved in the development of obesity, insulin resistance, and renal diseases; however, the role of this signaling on steatotic preneoplastic liver lesions is not fully elucidated. We determined the effects of the MR antagonist potassium canrenoate (PC) on MR/NOX signaling in hepatic steatosis and preneoplastic glutathione S transferase placental form (GST-P)-positive liver foci. Rats were subjected to a two-stage hepatocarcinogenesis model and fed with basal diet or high fat diet (HFD) that was co-administered with PC alone or in combination with the antioxidant alpha-glycosyl isoquercitrin (AGIQ). PC reduced obesity and renal changes (basophilic tubules that expressed MR and p22phox) but did not affect blood glucose tolerance and non-alcoholic fatty liver disease activity score (NAS) in HFD-fed rats. However, the drug increased the area of GST-P-positive liver foci that expressed MR and p22phox as well as increased expression of NOX genes (p22phox, Poldip2, and NOX4). PC in combination with AGIQ had the potential of inhibiting the effects of PC on the area of GST-P-positive liver foci and the effects were associated with increasing expression of an anti-oxidative enzyme (Catalase). The results suggested that MR/NOX signaling might be involved in development of preneoplastic liver foci and renal basophilic changes in HFD-fed rats; however, the impacts of PC were different in each organ. PMID- 30298851 TI - Transcatheter Aortic Valve Replacement for Severe Aortic Stenosis Complicated by Sigmoid Septum. AB - BACKGROUND: In patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS), a sigmoid septum, characterized by subaortic interventricular hypertrophy, often results in the need for new pacemaker implantation (PMI). In this study, we reviewed the feasibility and treatment efficacy of TAVR for AS in patients with a sigmoid septum. Methods and Results: Between 2011 and 2016, 48 patients (25.4%; mean age 84.9+/-5.4 years; 9 males) with a sigmoid septum and 141 (74.6%; mean age 82.9+/-5.5 years; 61 males) without underwent TAVR. Their operative outcomes, echocardiographic and electrocardiographic findings, and long-term outcomes were retrospectively compared. Second TAVR because of valve malposition was performed in 3 patients with a sigmoid septum (6.3%) and in 2 patients without a sigmoid septum (1.4%), with no significant difference between the 2 groups. Although there was no significant difference in valve hemodynamics between the 2 groups, sigmoid septum and deep implantation (implantation depth >=10 mm) were independent predictors of new PMI following TAVR. CONCLUSIONS: Although a sigmoid septum did not preclude the feasibility, safety, or efficacy of TAVR for severe AS, its presence was associated with new PMI. Our approach to TAVR in patients with a sigmoid septum may contribute to clinical outcomes comparable to those of patients without this pathology.

PMID- 30298852 TI - Prognostic Impact of Computed Tomography-Derived Abdominal Fat Area on Transcatheter Aortic Valve Implantation. AB - BACKGROUND: Obesity has previously been identified as an indicator of good prognosis in patients undergoing transcatheter aortic valve implantation (TAVI), an association known as the "obesity paradox". We investigated whether abdominal total fat area (TFA), visceral fat area (VFA), or subcutaneous fat area (SFA) are prognostic indicators of long-term clinical outcome in patients undergoing TAVI. Methods and Results: We retrospectively analyzed 100 consecutive patients who underwent TAVI between December 2013 and April 2017. TFA, VFA, and SFA were measured from routine pre-procedural computed tomography (CT). Patients were divided into 2 groups according to median TFA, VFA, or SFA, and we investigated the association of abdominal fat area with adverse clinical events, including all cause death and re-hospitalization due to worsening heart failure. At a median follow-up of 665 days, patients with higher SFA had significantly lower incidence of the composite outcome and all-cause death compared with patients with lower SFA (15.0% vs. 37.7%, P=0.025; and 8.9% vs. 23.7%, P=0.047, respectively). In contrast, patients with higher TFA or VFA did not show significant reduction in the incidences of the composite outcome or all-cause mortality. CONCLUSIONS: CT derived SFA had prognostic value in patients undergoing TAVI. PMID- 30298854 TI - Effects of different resin sealing therapies on nanoleakage within artificial non cavitated enamel lesions. AB - The aim of this study was to evaluate nanoleakage within the different lesion sealing therapies applied to artificial non-cavitated enamel lesions. Thirty-two human anterior teeth were used. Artificial subsurface enamel lesions were produced on the labial surfaces of teeth. The specimens were then randomly divided into three groups (n=10): Group I- Clinpro Sealant application; Group II- ExciTE F adhesive resin application; and Group III- ICON resin infiltrant application. Each group was further divided into two subgroups: control and thermocycler. Nanoleakage was calculated by the digital image analysis software. In the control and thermocycled groups, there was no statistically significant difference between the Groups I, II, and III (p>0.05). The only significant leakage scores were obtained between the Group III control and thermocycler groups (p=0.027). ICON infiltrant can be used as an alternative to dental adhesives and fissure sealants in the sealing of initial non-cavitated enamel lesions. But the resin may become more affected by the water sorption than other resin materials over time. More studies are needed to evaluate long-term durability of resin infiltrants. PMID- 30298855 TI - Effect of kinematic viscosity on the staining performance of caries detector dyes. AB - The relationship between performance of caries detector dyes and solvent molecular weight has been reported, but viscosity has not yet been investigated. Therefore, using extracted human teeth, we compared 6 experimental caries detector dyes with different viscosities to clarify the relationship between dye viscosity and staining performance in sclerotic dentin. Carious dentin started showing dentin staining when stained with caries detector dyes with kinematic viscosity>=263 mm2/s, showed no immunoreactivity for Streptococcus mutans on immunohistochemistry, and contained dentinal tubules free of debris on scanning electron microscopy. Samples stained using a caries detector dye with kinematic viscosity of 332 mm2/s contained calcification product-like debris in the dentinal tubules. These findings suggest that the caries detector dye has a threshold kinematic viscosity between 263 and 332 mm2/s at which sclerotic dentin and tissues beyond are not stained. The caries detector dye appears to control tooth dyeability based on solvent viscosity. PMID- 30298856 TI - Changes in the physical properties and color stability of aesthetic restorative materials caused by various beverages. AB - This study investigates the effects of various beverages on the wettability, microhardness, and color stability of aesthetic dental restorative materials. A contact angle analyzer, Vickers hardness tester, and spectrophotometer were used to characterize the properties of the materials and a total of 225 specimens were prepared: 75 each for a resin composite, compomer, and giomer. Ingestion of energy drinks and cola caused the greatest deterioration in wettability and microhardness, and coffee caused the most significant color change. In addition, the change in the resin composite was lower than that of the other restorative materials. The extent of change in the restorative materials increased with duration and frequency of contact with the beverages, so a reduction in the frequency of ingestion of these beverages is recommended. PMID- 30298857 TI - Structural and long-term mechanical properties from a resin-modified glass ionomer cement after various delays of light-activation. AB - This study aimed, after various delays of light-activation, to examine the microstructure of a resin-modified glass ionomer cement (RMGIC) by scanning electron microscopy (SEM) and to test its mechanical properties in short and long term. Five groups of Fuji II LC were investigated with different light-curing protocols. For each, SEM observations were undertaken with etched samples to selectively observe the organic polymer phase. Flexural strength and microhardness were also tested after 24 h and 12 months storage. SEM examination showed different images of the material according to the delay of light activation. At 24 h, there was a delay with maximal mechanical properties: 5 min for flexural strength, 10 min for microhardness. However, at 12 months, maximal mechanical properties were reached for the shortest delay. The competition between the acid-base and polymerization reactions results in the formation of a structurally and mechanically different material according to the delay of light activation. This delay should be adapted to the clinical situation. PMID- 30298858 TI - Ultrastructure and bonding properties of tribochemical silica-coated zirconia. AB - Tribochemical silica coating (TSC) is commonly used to pretreat zirconia surfaces prior to luting. Although many studies demonstrate an adhesion-promoting effect of TSC on zirconia, its actual interaction mechanism has not been fully elucidated. We therefore characterized the ultrastructure of TSC-treated zirconia and tested shear-bond strength. STEM/EDS disclosed a micro-roughened zirconia surface partially covered with fused Al and Si, while residual unfused silica particles could also still be detected. TSCtreated zirconia having received the solely silane primer exhibited a significantly lower shear-bond strength than zirconia on which the combined 10-MDP/silane primer was applied. SEM fracture analysis revealed residual silica particles on both the zirconia and cement sides. Correlative ultrastructural and chemical surface characterization revealed that TSC deposited an inhomogeneous silica layer on the zirconia surface, which explains why the solely silane coupling agent was less effective than the combined 10-MDP/silane ceramic primer for bonding to zirconia pretreated by TSC. PMID- 30298859 TI - Microhardness of bovine enamel after different fluoride application protocols. AB - The aim of the present study was to evaluate microhardness, mineral recovery and the enamel surface after the application of topical fluoride to artificial dental caries. Twenty-five bovine enamel blocks were prepared for artificial caries-like lesions and randomly divided into five groups (n=5): untreated (C control), 1.23% acidulated phosphate fluoride gel (APG), 2% neutral fluoride gel (NFG), 1.23% acidulated fluoride mousse (AFM) and fluoride varnish (5% Duraphat, DFV). Knoop microhardness (KHN) was evaluated after 7 and 14 days of treatment as well as 1 week after 28 days of treatment. Electron and confocal microscopy and energy dispersive spectroscopy were performed. KHN data were treated with two-way ANOVA (material*time) and Tukey's test at a 5% significance level. Differences were found among groups over time (p<0.001). Microhardness varied after 7 and 14 days of treatment and remained stable 1 week after 28 days of treatment. Mineral recovery and enamel topography varied among groups, with the fluoride varnish achieving the most uniform topography. PMID- 30298860 TI - Microtensile bond strengths of adhesively bonded polymer-based CAD/CAM materials to dentin. AB - This in vitro study aimed to evaluate the effect of two different polymer-based CAD/CAM materials; resin-nano ceramic (Lava Ultimate [LVU]) and composite (CERASMART [CS]), their different surface pre-treatments, and use of different resin cements on the uTBS of adhesively bonded CAD/CAM onlays to dentin. CAD/CAM materials were cut into slabs and divided into five groups according to the surface pre-treatments applied: Silane Primer, OptiBond XTR adhesive, Silane Primer+OptiBond XTR adhesive, Single Bond Universal (SBU), and RelyX Ceramic Primer+SBU. The LVU and CS specimens were bonded to the mid-coronal dentin of 50 noncarious human molars using NX3 resin cement with OptiBond XTR or RelyX Ultimate with SBU. uTBS was evaluated after 5,000 thermocycling and analysed with three-way-ANOVA and post-hoc Tukey's tests (p<0.05). The uTBS was significantly influenced by the type of CAD/CAM material (p<0.0001) surface pre-treatments (p<0.05) and resin cements (p<0.05). Regardless of the pre-treatments and resin cements, bonding of the composite CAD/CAM material to dentin was higher than the resin nano-ceramic material. PMID- 30298861 TI - Regional differences in colorectal cancer mortality between 2000 and 2013 in Republic of Korea. AB - OBJECTIVE: Colorectal cancer (CRC) is the 4th common site for cancer death in Republic of Korea. The aim of this study was to describe the trends of colorectal cancer mortality by regions. METHODS: CRC mortality trends in Republic of Korea by region were described using a Joinpoint regression model in both sexes. The annual percent changes (APC) were calculated for each segment. Visualization of the changes in mortality rate of colorectal cancer death rates by 16 geographic areas in both sexes between 2000-2004 and 2009-2013 were also conducted. RESULTS: CRC mortality rates of men showed decreasing trend after increase in Daegu, Gyeongsangnam-do and Chungcheongbuk-do between 2000 and 2013 based on the joinpoint model. While, Gwangju, Jeollabuk-do, Jeollanam-do, Gyeongsangbuk-do showed increase in CRC mortality during the same period. For women, CRC mortality of Seoul, Incheon, Daejeon and Gyeongsangnam-do started to decrease in 2005, 2003, 2007 and 2006 respectively. The mortality rate for CRC in the eastern regions, which had relatively low rates of CRC among men in 2000 to 2004, reached a level similar to that in the northwestern regions of 2009 to 2013, while the highest CRC mortality rates in women was observed in Chungcheongbuk-do. CONCLUSIONS: Reduction in CRC mortality varied across 16 metropolitan cities and provinces in men, and the visualization pattern showed that the east side of South Korea had the least progress in mortality reduction. PMID- 30298862 TI - Older Adult Males Who Worked at Small-sized Workplaces Have an Increased Risk of Decline in Instrumental Activities of Daily Living: A Community-based Prospective Study. AB - BACKGROUND: To examine the relationship of working history from early adulthood through old age with instrumental activities of daily living (IADL). METHODS: Analyzed participants were 5,857 community-dwelling older Japanese people aged >=65. Using the Tokyo Metropolitan Institute of Gerontology Index of Competence, IADL decline was defined as individuals who had no IADL dependence at baseline, but were deemed as dependent in IADL at follow-up. Work history was based on working status at baseline, total working years, and information concerning the longest held job, including occupation, employment pattern, and workplace size (number of employees). We conducted multiple logistic regression analyses and estimated the odds ratio (OR) for IADL decline with 95% confidence interval (CI) by gender. RESULTS: At the 33-month follow-up, 428 men (16.6%) and 275 women (8.4%) developed IADL decline. After covariate adjustments, men with unstable employment reported significantly increased IADL decline (OR=1.52, 95% CI=1.19 1.95) compared to men with stable employment, and men who worked in small workplaces with 1-49 employees had an increased risk for IADL decline (1.53, 1.21 1.93) compared to men in large-sized workplaces with >=50 employees. After mutual adjustment for all working history items, only the association between small workplaces and IADL decline remained significant in men (1.37, 1.03-1.84). Among women, none of working history items was associated with IADL decline. CONCLUSION: Our results suggest that not only promoting older people's workforce participation, but also providing workers employed at small workplaces with sufficient occupational health services, may be effective in helping retain male IADL in later life.

AB - The Hisayama Study is a population-based prospective cohort study designed to evaluate the risk factors for lifestyle-related diseases, such as stroke, coronary heart disease, hypertension, diabetes, and dementia, in a general Japanese population. The prospective follow-up surveys have been conducted in subjects aged 40 or older since 1961. Notable characteristics of this study include its high participation rate (70-80% of all residents aged 40 or older), high follow-up rate (99% or over), and high autopsy rate (approximately 75% of deceased cases). The Hisayama Study has provided valuable evidence of secular change in the prevalence and incidence of several lifestyle-related disease and their risk factors. The study has thereby contributed to elucidation of the preventive strategies for lifestyle-related disease. Research efforts in this cohort are ongoing and will provide additional data for the improvement of human health and longevity.

PMID- 30298865 TI - Improvement of Glucose Metabolism Following Long-Term Taurocholic Acid Gavage in a Diabetic Rat Model. AB - BACKGROUND Bile acids (BAs) are signaling molecules that participate in maintaining glucose homeostasis. Acute enteral infusion of BAs potently reduces the glycemic response to glucose, associated with an increase of incretin hormones. However, the effect of long-term supplementation of BAs on glucose metabolism has not been fully investigated. MATERIAL AND METHODS Thirty diabetic rats were assigned to a control group (n=10), a low TCA group (L-TCA group, n=10), and a high TCA group (H-TCA group, n=10). Rats in the control group were fed a regular high-fat diet (HFD), while rats in the L-TCA group and H-TCA group were fed a TCA (taurocholic acid)-mixed HFD with the concentrations of 0.05% and 0.3%, respectively, to control the intake of HFD and TCA. Energy intake, body weight, serum insulin, glucose tolerance, insulin sensitivity, GLP-1, and total serum BAs were measured at week 2 and week 12. RESULTS At week 2 there were no significant differences in body weight, daily energy intake, glucose tolerance, serum insulin, insulin sensitivity, GLP-1, or fasting total serum BAs between the 3 groups. At week 12, fasting blood glucose and intragastric glucose tolerance were better in the H-TCA group, with significantly greater insulin and GLP-1 secretion and better insulin sensitivity; no significant differences in body weight, energy intake, or total fasting serum BAs were observed. CONCLUSIONS Long term supplementation with small doses of TCA was demonstrated to improve glucose metabolism in a diabetic rat model and may be a potential target for diabetes control. PMID- 30298867 TI - Recent advances in single cell manipulation and biochemical analysis on microfluidics. AB - Single cell analysis has become of great interest with unprecedented capabilities for the systematic investigation of cell-to-cell variation in large populations. Rapid and multi-parametric analysis of intercellular biomolecules at the single cell level is imperative for the improvement of early disease diagnosis and personalized medicine. However, the small size of cells and the low concentration levels of target biomolecules are critical challenges for single cell analysis. In recent years, microfluidic platforms capable of handling small-volume fluid have been demonstrated to be powerful tools for single cell analysis. In addition, microfluidic techniques allow for precise control of the localized microenvironment, which yield more accurate outcomes. Many different microfluidic techniques have been greatly improved for highly efficient single-cell manipulation and highly sensitive detection over the past few decades. To date, microfluidics-based single cell analysis has become the hot research topic in this field. In this review, we particularly highlight the advances in this field during the past three years in the following three aspects: (1) microfluidic single cell manipulation based on microwells, micropatterns, droplets, traps and flow cytometric methods; (2) detection methods based on fluorescence, mass spectrometry, electrochemical, and polymerase chain reaction-based analysis; (3) applications in the fields of small molecule detection, protein analysis, multidrug resistance analysis, and single cell sequencing with droplet microfluidics. We also discuss future research opportunities by focusing on key performances of throughput, multiparametric target detection and data processing. PMID- 30298866 TI - P-glycoprotein targeted photodynamic therapy of chemoresistant tumors using recombinant Fab fragment conjugates. AB - P-glycoprotein (Pgp) has been considered as a major cause of cancer multidrug resistance; however, clinical solutions to overcome this drug resistance do not exist despite the tremendous endeavors. The lack of cancer specificity is a main reason for clinical failure of conventional approaches. Targeted photodynamic therapy (PDT) is highly cancer specific by combining antibody targeting and locoregional light irradiation. We aimed to develop Pgp-targeted PDT using antibody-photosensitizer conjugates made of a recombinant Fab fragment. We prepared the photosensitizer conjugates by expressing a recombinant Fab fragment and specifically linking IR700-maleimide at the C-terminal of the Fab heavy chain. In vitro studies showed that the Fab conjugates specifically bind to Pgp. Their phototoxicity was comparable to full antibody conjugates when assayed with conventional 2-D cell culture, but they outperformed the full antibody conjugates in a 3-D tumor spheroid model. In a mouse xenograft model of chemoresistant tumors, Fab conjugates showed Pgp specific delivery to chemoresistant tumors. Upon irradiation with near-infrared light, they caused rapid tumor shrinkage and significantly prolonged the survival of tumor-bearing mice. Compared to the full antibody conjugates, Fab conjugates took a shorter time to reach peak tumor levels and achieved a more homogeneous tumor distribution. This allows light irradiation to be initiated at a shorter time interval after the conjugate injection, and thus may facilitate clinical translation. We conclude that our targeted PDT approach provides a highly cancer-specific approach to combat chemoresistant tumors, and that the conjugates made of recombinant antibody fragments are superior to full antibody conjugates for targeted PDT.

AB - Free-base phthalocyanine forms distinct interfacial phases and thin films on hexagonal boron nitride including a monolayer arrangement as determined using high resolution atomic force microscopy.

AB - MyD88 (myeloid differentiation factor 88) is an important protein in innate immunity. Two structural domains of MyD88 have been well characterized separately, but the global architecture of full-length MyD88 remained unclear. Here, we propose an autosuppressive mechanism of MyD88 regulated by the intramolecular interaction between the two domains.

PMID- 30298874 TI - Re-entrant supramolecular interactions in inverse-melting alpha-cyclodextrin.4 methylpyridine.water mixtures: an NMR study. AB - Inverse melting alpha-cyclodextrin.4-methylpyridine.H2O ternary mixtures were studied via solution, high-resolution magic-angle-spinning and 2D-NOESY NMR spectroscopy with the aim of unveiling the supramolecular driving force for the unusual inverse-melting phase transition. The role of solvent-solvent interactions as well as solvent-solute interactions in the emergence of the inverse-melting phenomenon is revealed. A surprising re-entrant solvent-solvent interaction is found in the system and in the 4-methylpyridine.water solvent system, supporting the non-coincidental relationship between inverse melting and re-entrant phase transitions, at least in the present system. PMID- 30298877 TI - The peculiar effect of water on ionic liquids and deep eutectic solvents. AB - Ionic liquids (ILs) and deep eutectic solvents (DESs) have been suggested as eco friendly alternatives to organic solvents. A trace amount of water is often unavoidable as impurity, and water is also added on purpose to reduce their problematically high viscosity and lower their high price. Understanding the distinct effects of water on the properties of ILs/DESs is highly important. In this review, we collect published experimental and theoretical results for IL/DES H2O systems at varied water concentrations and analyze them. Results from mechanistic studies, thermodynamic modelling and advanced experiments are collected and critically discussed. Six commonly studied IL/DES-H2O systems were selected to map experimental observations onto microscopic results obtained in mechanistic studies. A great variety of distinct contours of the excess properties can be observed over the entire compositional range, indicating that the properties of IL/DES-H2O systems are highly unpredictable. Mechanistic studies clearly demonstrate that the added H2O rapidly changes the heterogeneous 3D structures of pure ILs/DESs, leading to very different properties and behaviour. There are similarities between aqueous electrolytes and IL/DES solutions but the bulky and asymmetric organic cations in ILs/DESs do not conform to the standard salt dissolution and hydration concepts. Thermodynamic modelling previously assumes ILs/DESs to be either a neutral ion-pair or completely dissociated ions, neglecting specific ion hydration effects. A new conceptual framework is suggested for thermodynamic modelling of IL/DES-H2O binary systems to enable new technologies for their practical applications.

AB - Excitons in the molecular aggregates of chromophores are key participants in important processes such as photosynthesis or the functioning of organic photovoltaic devices. Therefore, the exploration of exciton dynamics is crucial. Here we report on exciton localization during excited-state dynamics of the recently synthesized tetracene trimer [Liu et al., Org. Lett., 2017, 19, 580]. We employ the surface hopping approach to nonadiabatic molecular dynamics in conjunction with the long-range corrected time-dependent density functional tight binding (LC-TDDFTB) method [Humeniuk and Mitric, Comput. Phys. Commun., 2017, 221, 174]. Utilizing a set of descriptors based on the transition density matrix, we perform comprehensive analysis of exciton dynamics. The obtained results reveal an ultrafast exciton localization to a single tetracene unit of the trimer during excited-state dynamics, along with exciton transfer between units.

AB - Rechargeable redox flow batteries are being developed for medium and large-scale stationary energy storage applications. Flow batteries could play a significant role in maintaining the stability of the electrical grid in conjunction with intermittent renewable energy. However, they are significantly different from conventional batteries in operating principle. Recent contributions on flow batteries have addressed various aspects, including electrolyte, electrode, membrane, cell design, etc. In this review, we focus on the less-discussed practical aspects of devices, such as flow fields, stack and design considerations for developing high performance large-scale flow batteries. Finally, we provide suggestions for further studies on developing advanced flow batteries and large-scale flow battery stacks. PMID- 30298881 TI - Conformationally flexible arylethynyl bis-urea receptors bind disparate oxoanions with similar, high affinities. AB - Conformationally flexible hosts with relatively small binding pockets are seldom shown to bind oxoanions preferentially over other guests. Herein, we disclose the binding of diprotic, monoprotic, and aprotic tetrahedral oxoanions with three different pyridylethynyl bis-urea scaffolds. In less polar solvent, the trend in association constants appears to be heavily influenced by solvation and entropic effects. However, in a more polar solvent, the trend in association constants matches that of the pKa of the conjugate acid of the anionic guest, as expected for H-bond donating hosts. PMID- 30298882 TI - Terephthalate-based cobalt hydroxide: a new electrode material for supercapacitors with ultrahigh capacitance. AB - Searching for new electrode materials is one of the key tasks in developing high performance supercapacitors. In this work, as a layered hydroxyl derivative, terephthalate-based cobalt hydroxide, Co2(OH)2(C8H4O4), is successfully prepared in situ on nickel foam through a simple hydrothermal route. The scanning electron microscopy results reveal that the products are composed of massive double-blade lath crystals grown along the a-axis. The as-obtained Ni-foam-supported Co2(OH)2(C8H4O4) is directly used as the positive electrode of supercapacitors without further treatment. The resulting Co2(OH)2(C8H4O4) electrode exhibits ultrahigh charge storage capacity with the specific capacity of 9.36 C cm-2 (1261 C g-1) at a current density of 10 mA cm-2 (0.5 A g-1) and good cycling stability with the capacity retention of 82.4% over 5000 cycles at a current density of 50 mA cm-2. In combination with activated carbon as the negative electrode in 3 M KOH aqueous electrolyte, the constructed asymmetric supercapacitor delivers a high energy density of 30.62 W h kg-1 at a power density of 221 W kg-1 within a voltage window of 1.5 V. These encouraging electrochemical performances enable the developed terephthalate-based cobalt hydroxide to be a promising electrode material for supercapacitor applications. PMID- 30298883 TI - Applying MOF+ technique for in situ preparation of a hybrid material for hydrogenation reaction. AB - In this study, we present the first case of applying the MOF+ technique for in situ preparation of a hybrid material, namely, Zn-MOF-74@ (Pd@Fe2O3). This as synthesized material can well maintain both the integrity of the framework and porosity. Notably, Zn-MOF-74@(Pd@Fe2O3) exhibits outstanding catalytic performance in the hydrogenation reaction of alkene and semihydrogenation reaction of phenylacetylene, thus providing a new guideline for the design of MOF based hybrid materials for catalytic purpose. PMID- 30298884 TI - Facile synthesis and magnetic and electrical properties of layered chalcogenides K2CoCu3Q4 (Q for S and Se). AB - Layered transition-metal chalcogenides have attracted great interest due to their unique electronic and optical properties. Here, we represent two layered quaternary chalcogenides K2CoCu3S4 and K2CoCu3Se4 prepared by a convenient hydrothermal route. From powder XRD and TEM analyses, K2CoCu3Q4 possesses a tetragonal ThCr2Si2-type structure with a random arrangement of Co and Cu atoms. The phase purity of the samples was confirmed by ICP, SEM, and EDS analyses, and the oxidation states of Co and Cu atoms were determined to be +3 and +1 by XPS spectra. Both samples show a weak ferromagnetic behavior at low temperature induced by spin-canted antiferromagnetic ordering. The temperature dependent resistivity, rho(T), reveals a metallic nature for stoichiometric K2CoCu3S4. The semiconducting behavior of K2CoCu3Se4 could be explained better by variable range hopping (VRH) rather than adiabatic small polaron hopping (SPH). This new series of layered chalcogenides may offer a promising candidate for potential electronic applications.

AB - In this paper, a regioselective, efficient and convenient synthesis of 2 aminobenzophenones through acylation of anilines with alpha-oxocarboxylic acids assisted by tert-butyl nitrite is presented. Interestingly, tert-butyl nitrite acts as not only an efficient and mild nitrosation reagent, but also a sustainable oxidant required in the Pd(ii)-catalyzed decarboxylative acylation. Meanwhile, the NO unit turned out to be an easily introduced and readily removable directing group for the regioselective acylation. PMID- 30298891 TI - Sub-kT/q switching in In2O3 nanowire negative capacitance field-effect transistors. AB - Limited by the Boltzmann distribution of electrons, the sub-threshold swing (SS) of conventional MOSFETs cannot be less than 60 mV dec-1. This limitation hinders the reduction of power dissipation of the devices. Herein, we present high performance In2O3 nanowire (NW) negative capacitance field-effect transistors (NC FETs) by introducing a ferroelectric P(VDF-TrFE) layer in a gate dielectric stack. The fabricated devices exhibit excellent gate modulation with a high saturation current density of 550 MUA MUm-1 and an outstanding SS value less than 60 mV dec-1 for over 4 decades of channel current. The assembled inverter circuit can demonstrate an impressive voltage gain of 25 and a cut-off frequency of over 10 MHz. By utilizing the self-aligned fabrication scheme, the device can be ultimately scaled down to below 100 nm channel length. The devices with 200 nm channel length exhibit the best performances, in which a high on/off current ratio of >107, a large output current density of 960 MUA MUm-1 and a small SS value of 42 mV dec-1 are obtained at the same time. All these would not only evidently demonstrate the potency of NW NC-FETs to break through the Boltzmann limit in nanoelectronics, but also open up a new avenue to low-power transistors for portable products. PMID- 30298892 TI - Label free localization of nanoparticles in live cancer cells using spectroscopic microscopy. AB - Gold nanoparticles (GNPs) have become essential tools used in nanobiotechnology due to their tunable plasmonic properties and low toxicity in biological samples. Among the available approaches for imaging GNPs internalized by cells, hyperspectral techniques stand out due to their ability to simultaneously image and perform spectral analysis of GNPs. Here, we present a study utilizing a recently introduced hyperspectral imaging technique, live-cell PWS, for the imaging, tracking, and spectral analysis of GNPs in live cancer cells. Using principal components analysis, the extracellular or intracellular localization of the GNPs can be determined without the use of exogenous labels. This technique uses wide-field white light, assuring minimal toxicity and suitable signal-to noise ratio for spectral and temporal resolution of backscattered signal from GNPs and local cellular structures. The application of live-cell PWS introduced here could make a great impact in nanomedicine and nanotechnology by giving new insights into GNP internalization and intracellular trafficking. PMID- 30298893 TI - Ultrafast excited state dynamics of nonfluorescent cyclopheophorbide-a enol, a catabolite of chlorophyll-a detoxified in algae-feeding aquatic microbes. AB - For photosynthetic organisms that nourish the earth's biosphere, chlorophylls (Chls) are the major pigments utilized for light harvesting and primary charge separation. Although Chl molecules are effective photosensitizers, they are inevitably phototoxic to living organisms due to the facile generation of highly oxidative singlet oxygen (1O2) through triplet energy transfer from their photoexcited states to oxygen molecules. Such phototoxicity of Chls is a major problem for translucent microbes that feed on photosynthetic algae. Recently, it has been reported that the metabolic conversion of Chls-a/b to 132,173 cyclopheophorbide-a/b enols (cPPB-a/bEs) is the detoxification mechanism for algivorous protists. cPPB-a/bEs are colored pi-conjugated cyclic tetrapyrroles but are nonfluorescent due to efficient nonradiative decay. In this study, femtosecond time-resolved transient absorption spectroscopy was applied to cPPB aE with the aim of understanding its quenching mechanism. As a result, we have captured the ultrafast generation of an intermediate state (~140 fs) that leads to the rapid internal conversion to the ground state (~450 fs). PMID- 30298894 TI - Nutritional characterization and shelf-life of packaged microgreens. AB - Besides the variety of colours and flavours, microgreens show interesting nutritional properties, mainly regarding their contents of mineral nutrients and bioactive compounds. To date, the literature has prevalently focused on the individual nutritional features of microgreens usually belonging to Brassicaceae. The present study reports an articulated nutritional profile of six genotypes of microgreens, belonging to three species and two families: chicory (Cichorium intybus L., Puglia's local variety 'Molfetta', CM, and cultivar 'Italico a costa rossa', CR) and lettuce (Lactuca sativa L. Group crispa, cultivar 'Bionda da taglio', LB, and 'Trocadero', LT), from Asteraceae; and broccoli (Brassica oleracea L. Group italica Plenk, Puglia's local variety 'Mugnuli', BM, and cultivar 'Natalino', BN) from Brassicaceae. All the microgreens, except LB, can be considered good sources of Ca, whilst LT and CM also showed considerable amounts of K. As regards bioactive compounds, Brassica microgreens were the richest in phenolic antioxidants. The microgreens also presented higher amounts of alpha-tocopherol and carotenoids compared to mature vegetables. In particular, broccoli microgreens and LB showed the highest amounts of vitamin E, while Asteraceae microgreens presented the highest levels of carotenoids. Due to their delicate tissues, fresh cut microgreens showed a shelf life not exceeding ten days at 5 degrees C. The results obtained highlight the possibility to exploit genetic biodiversity in order to obtain tailored microgreens with the desired nutritional profiles, with particular regard to mineral nutrients and bioactive compounds. Appropriate pre- and post-harvest strategies should be developed, so as to allow microgreens to retain as long as possible their nutritional value.

AB - C-Alkylation of N-alkylamides with styrenes is reported, proceeding in ambient air/moisture to give arylbutanamides and pharmaceutically-relevant scaffolds in excellent mass balance. Various amide and styrene derivatives were tolerated, rapidly affording molecular complexity in a single step; thus highlighting the future utility of this transformation in the synthetic chemistry toolbox. Reaction scalability (up to 65 g h-1 product) was demonstrated using a Microwave Flow reactor, as the first example of a C-alkylation reaction using styrenes in continuous flow. PMID- 30298896 TI - Endothelial, smooth muscle and fibroblast cell sheet fabrication from self assembled thermoresponsive poly(glycidyl ether) brushes. AB - In this study, we introduce a platform to fabricate human dermal fibroblast (HDF), human aortic smooth muscle cell (HAoSMC) and human umbilical vein endothelial cell (HUVEC) sheets using thermoresponsive poly(glycidyl ether) coatings. Copolymer brushes based on glycidyl methyl ether (GME) and ethyl glycidyl ether (EGE) were self-assembled onto polystyrene (PS) culture substrates via the physical adsorption of a hydrophobic, photoreactive benzophenone anchor block based on the monomer 4-[2-(2,3-epoxypropoxy)ethoxy]benzophenone (EEBP). The directed self-assembly of well-defined, end-tethered poly(GME-ran-EGE)-block poly(EEBP) (PGE) brushes was achieved via the selective, EEBP-driven adsorption of the asymmetric block copolymer from dilute aqueous solution below its cloud point temperature (CPT). Subsequently, the PGE brush layers were covalently immobilized onto the PS surfaces by irradiation with UV light and characterized by ellipsometry, static water contact angle (CA) measurements and atomic force microscopy (AFM). We found that, by decreasing the temperature from 37 to 20 degrees C, the coatings undergo a pancake-to-brush transition, which triggers cell sheet detachment. In addition, cell culture parameters were optimized to allow proper adhesion and controlled detachment of confluent HDF, HAoSMC and HUVEC sheets, which can be applied in vascular tissue engineering.

AB - A simple cumene (isopropylbenzene, IPB) promoted auto-oxidation involved tandem radical cyclization of N-methacryloyl benzamides using stable and easy-to-handle CBr4 as the bromine source is described. This strategy provides an efficient and practical approach for the synthesis of bromine containing isoquinolinediones. This method also presents a new way to generate bromine radicals using a mild auto-oxidation pathway. PMID- 30298898 TI - Opposed flow focusing: evidence of a second order jetting transition. AB - We propose a novel microfluidic "opposed-flow" geometry in which the continuous fluid phase is fed into a junction in a direction opposite to the dispersed phase. This pulls out the dispersed phase into a micron-sized jet, which decays into micron-sized droplets. As the driving pressure is tuned to a critical value, the jet radius vanishes as a power law down to sizes below 1 MUm. By contrast, the conventional "coflowing" junction leads to a first order jetting transition, in which the jet disappears at a finite radius of several MUm, to give way to a "dripping" state, resulting in much larger droplets. We demonstrate the effectiveness of our method by producing the first microfluidic silicone oil emulsions with a sub micron particle radius, and utilize these droplets to produce colloidal clusters. PMID- 30298899 TI - 3-Arm star pyrene-functional PMMAs for efficient exfoliation of graphite in chloroform: fabrication of graphene-reinforced fibrous veils. AB - 3-Arm PMMAs end-functionalized by pyrene were designed as dispersing/stabilizing agents for the liquid-phase exfoliation of graphite in low-boiling point solvents like chloroform. The synthetic procedure comprised ARGET ATRP controlled polymerization, click chemistry and the quaternization reaction of triazole, ensuring tailor-made, well-defined pyrene-functional star PMMAs. Among a series of different pyrene-functional macromolecular topologies, the (PMMA-py2)3 proved the most efficient exfoliation agent giving relatively high graphene concentration (0.36 mg ml-1) at exceptionally low polymer/graphite mass ratio (mP/mGF = 0.003) and short sonication time (3 h). A 5-cycle iterative procedure relying on the redispersion of the sediment was developed yielding CG = 1.29 mg ml-1 with 14.8% exfoliation yield, under the favorable conditions of 10.5 h total shear mixing/tip sonication time and overall mP/mGF ratio as low as 0.15. In parallel, all-atom molecular dynamics simulations were conducted which helped understand the mechanism by which pyrene-functional macromolecular topologies act as efficient dispersing agents of graphene. Finally the G@(PMMA-Py)3 hybrids were well dispersed into the PMMA matrix by electrospinning to fabricate graphene based nanocomposite fibrous veils. These graphene/polymer nanocomposites exhibited enhanced stiffness and strength by a factor of 4.4 with 1.5 wt% graphene hybrids as nanofillers. PMID- 30298900 TI - Structurally tunable plasmonic absorption bands in a self-assembled nano-hole array. AB - In this paper, we demonstrate a theoretical and experimental study on a nano-hole array that can realize perfect absorption in the visible and near-infrared regions. The absorption spectrum can be easily controlled by adjusting the structural parameters including the radius and period of the nano-hole, and the maximal absorption can reach 99.0% in theory. In order to clarify the physical mechanism of the absorber, we start from the extraordinary optical transmission supported by the nano-hole array in a thin metallic film coated on a glass substrate, and then analyse the perfect absorption in the metal-insulator-metal structure. The surface plasmon modes supported by the nano-hole array are completely clarified and both the FDTD simulation and waveguide theory are used to help us understand the physical mechanism, which can provide a new perspective in designing this kind of perfect absorber. In addition, the nano-hole array can be fabricated by simple and low-cost nanosphere lithography, which makes it a more appropriate candidate for spectroscopy, photovoltaics, photodetectors, sensing, and surface enhanced Raman scattering. PMID- 30298901 TI - Personalized Goal Attainment in Dementia Care: Measuring What Persons with Dementia and Their Caregivers Want. AB - OBJECTIVES: To develop a process of goal-setting and measurement of goal attainment in a dementia care management program. DESIGN: Observational. SETTING: Dementia care management program in an urban academic medical center. PARTICIPANTS: Persons with dementia (N=101) and their caregivers; nurse practitioner dementia care managers (N=5). INTERVENTION: Specification of a personalized health goal and action plan and measurement of goal attainment using goal attainment scaling in a clinical care visit. MEASUREMENTS: Goal attainment at 6 and 12 months; focus groups of 5 dementia care managers. RESULTS: Eighty four percent of participant goals were nonmedical, 47% were related to quality of life, and 29% were caregiver support goals. Eighty-eight percent of participants felt that the goal they set was meaningful and 74% that the goal-setting process captured something different from usual care, and 85% found the process helpful in planning for future care. At 6 months, 74% of dyads had achieved or exceeded their expected level of goal attainment. Dementia care managers felt that the goal-setting process improved their understanding of what was most important to the patient, helped set expectations about disease progression and care needs, and provided positive reinforcement when goals were accomplished and an opportunity for revision when goals were not met. CONCLUSION: Goal setting using goal attainment scaling can be incorporated into the care of persons with dementia to establish and attain person-centered goals. Research is needed to further develop personalized goal attainment as an outcome measure for dementia care. J Am Geriatr Soc 66:2120-2127, 2018.

AB - Thymus-derived regulatory T cells (tTregs) play pivotal roles in immunological self-tolerance and homeostasis. A majority of tTregs are reactive to self antigens and are constantly exposed to antigenic stimulation. Despite this continuous stimulation, tTreg and conventional T-cell populations remain balanced during homeostasis, but the mechanisms controlling this balance are unknown. We previously reported a form of activation-induced cell death, which is dependent on p53 (p53-induced CD28-dependent T-cell apoptosis, PICA). Under PICA-inducing conditions, tTregs survive while a majority of conventional T cells undergo apoptosis, suggesting there is a survival mechanism that protects tTregs. Here, we report that the expression of RasGRP1 (Ras guanyl-releasing protein 1) is required for PICA, as conventional T cells isolated from RasGRP1-deficient mice become resistant to PICA. After continuous stimulation, tTregs express a substantially lower amount of RasGRP1 compared to conventional T cells. This reduced expression of RasGRP1 is dependent on TGF-beta, as addition of TGF-beta to conventional T cells reduces RasGRP1 expression. Conversely, RasGRP1 expression in tTregs increases when TGF-beta signaling is inhibited. Together, these data show that RasGRP1 expression is repressed in tTregs by TGF-beta signaling and suggests that reduced RasGRP1 expression is critical for tTregs to resist apoptosis caused by continuous antigen exposure. PMID- 30298905 TI - Model-assisted process characterization and validation for a continuous two column protein A capture process. AB - In this study we introduce three process characterization approaches toward validation of continuous twin-column capture chromatography (CaptureSMB), referred to as "standard," "model assisted," and "hybrid." They are all based on a traditional risk-based approach, using process description, risk analysis, design-of-experiments (DoE), and statistical analysis as essential elements. The first approach, the "standard" approach uses a traditional experimental DoE to explore the design space of the high-ranked process parameters for the continuous process. Due to the larger number of process parameters in the continuous process, the DoE is extensive and includes a larger number of experiments than an equivalent DoE of a single column batch capture process. In the investigated case, many of the operating conditions were practically infeasible, indicating that the design space boundaries had been chosen inappropriately. To reduce experimental burden and at the same time enhance process understanding, an alternative "model assisted" approach was developed in parallel, employing a chromatographic process model to substitute experimental runs by computer simulations. Using the "model assisted" approach only experimental conditions that were feasible in terms of process yield constraints (>90%) were considered for statistical analysis. The "model assisted" approach included an optimization part that identified potential boundaries of the design space automatically. In summary, the "model assisted" approach contributed to increased process understanding compared to the "standard" approach. In this study, a "hybrid" approach was also used containing the general concepts of the "standard" approach but substituting a number of its experiments by computer simulations. The presented approaches contain essential elements of the Food and Drug Administration's process validation guideline. PMID- 30298906 TI - The prognostic value of 3 commonly measured blood parameters and geriatric assessment to predict overall survival in addition to clinical information in older patients with cancer. AB - BACKGROUND: The current study was performed to evaluate the prognostic value of laboratory parameters and geriatric assessment (GA) in addition to a baseline model with clinical information regarding overall survival (OS) in patients with cancer. METHODS: GA was systematically performed in patients aged >=70 years. The baseline model consisted of age, tumor type, and stage of disease. The incremental prognostic values of the GA as a whole (10-item GA) and laboratory parameters were assessed separately and combined. The parameters included hemoglobin (Hb), albumin, C-reactive protein (CRP), and the Glasgow Prognostic Score (GPS). Analyses were conducted with continuous and dichotomized variables. Cox models were compared based on Akaike information criterion (DeltaAIC) and their discriminatory ability was assessed using the concordance probability estimate (CPE). RESULTS: A total of 328 patients were considered for this analysis. The baseline model had a CPE of 0.725. The addition of CRP, albumin, and Hb combined resulted in the best performing model (DeltaAIC: 40.12 and CPE: 0.757) among the laboratory parameters. However, the 10-item GA improved the baseline model even more (DeltaAIC: 46.03 and CPE: 0.769). Similar results were observed in the analysis with dichotomous variables. The addition of the 3 laboratory parameters (CRP, albumin, and Hb) improved the CPE by 1.4% compared with the baseline model already extended with the 10-item GA. The CPE increase (1.7%) was the highest with the GPS in the analysis with dichotomous variables. CONCLUSIONS: GA appears to add slightly more prognostic information than laboratory parameters in addition to clinical information. The laboratory parameters have an additional prognostic value beyond clinical and geriatric information. PMID- 30298907 TI - Tuberous sclerosis-associated neuropsychiatric disorders: a paediatric cohort study. AB - AIM: We aimed to study tuberous sclerosis-associated neuropsychiatric disorders (TAND) in children and adolescents with tuberous sclerosis complex (TSC). METHOD: Retrospective and prospective cohort study conducted at a Paediatric Neurology Unit of an Italian Tertiary Care Hospital. Clinical and neuroimaging data were reviewed. Scores for neurological and epilepsy outcomes (Extended Glasgow Outcome Scale, Paediatric Version and Early Childhood Epilepsy Severity Scale modified), semi-structured interviews (authorized Italian version of the TAND checklist and Vineland Adaptive Behavior Scales) and questionnaires (Child Behavior Checklist [CBCL]) were applied at last follow-up. RESULTS: Thirty-two patients with TSC (age range 1-19y) were enrolled. Eighty-eight per cent had at least one TAND and 47% had intellectual disability. The TAND checklist showed internalizing problems in 25.8% of cases (vs 41.9% by CBCL), and externalizing problems in 41.9% (vs 9.7% by CBCL). TAND prevailed in patients with de novo mutation of TSC2, high tuber load, and severe neurological and epilepsy outcomes. INTERPRETATION: In our cohort, 78% of patients had more than four TAND behavioural problems; nevertheless, they did not show a constant and specific neuropsychiatric profile. Clinical, neurophysiological, and neuroradiological features were associated with several TAND. The TAND checklist appeared more effective than the CBCL, particularly in detecting externalizing problems. WHAT THIS PAPER ADDS: The Tuberous sclerosis-associated neuropsychiatric disorders (TAND) checklist is an effective tool for TAND screening. The TAND checklist helps define psychopathological and neuropsychiatric aspects in paediatric patients with Tuberous sclerosis complex (TSC). TAND were found in 88% of patients with TSC, whilst 78% had more than four TAND. TAND distribution depends on different clinical and neuroradiological features. PMID- 30298908 TI - Trophoblast-endothelium signaling involves angiogenesis and apoptosis in a dynamic bioprinted placenta model. AB - Trophoblast invasion and remodeling of the maternal spiral arteries are required for pregnancy success. Aberrant endothelium-trophoblast crosstalk may lead to preeclampsia, a pregnancy complication that has serious effects on both the mother and the baby. However, our understanding of the mechanisms involved in this pathology remains elementary because the current in vitro models cannot describe trophoblast-endothelium interactions under dynamic culture. In this study, we developed a dynamic three-dimensional (3D) placenta model by bioprinting trophoblasts and an endothelialized lumen in a perfusion bioreactor. We found the 3D printed perfusion bioreactor system significantly augmented responses of endothelial cells by encouraging network formations and expressions of angiogenic markers, cluster of differentiation 31 (CD31), matrix metalloproteinase-2 (MMP2), matrix metalloproteinase-9 (MMP9), and vascular endothelial growth factor A (VEGFA). Bioprinting favored colocalization of trophoblasts with endothelial cells, similar to in vivo observations. Additional analysis revealed that trophoblasts reduced the angiogenic responses by reducing network formation and motility rates while inducing apoptosis of endothelial cells. Moreover, the presence of endothelial cells appeared to inhibit trophoblast invasion rates. These results clearly demonstrated the utility and potential of bioprinting and perfusion bioreactor system to model trophoblast endothelium interactions in vitro. Our bioprinted placenta model represents a crucial step to develop advanced research approach that will expand our understanding and treatment options of preeclampsia and other pregnancy-related pathologies. PMID- 30298909 TI - Beliefs About Moral Obligation Structure Children's Social Category-Based Expectations. AB - Young children view social category members as morally obligated toward one another, and expect these obligations to shape people's social behavior. The present work investigates how children specify which behaviors are constrained by social categories in this way. In two studies (N = 128), 4- and 5-year-old children predicted that morally positive behaviors would be directed toward in group members, and that morally negative behaviors would be directed toward out group members, but did not hold equally strong expectations about behaviors described as positive or negative for reasons irrelevant to morality. Thus, notions of morality are embedded within children's representations of social categories, such that when learning about novel moral norms, children immediately expect those obligations to uniquely hold within social groups. PMID- 30298910 TI - Early Literacy Predictors and Second-Grade Outcomes in Children Who Are Hard of Hearing. AB - This study contrasted the early literacy outcomes of children who are hard of hearing (CHH) with children with normal hearing (CNH). At age 5, prereading skills of oral language, phonological processing, and print knowledge were examined in CHH (N = 180) and CNH (N = 80). The CHH had poorer oral language and phonological processing abilities than the CNH but comparable knowledge of print. At age 8, measures of word reading, and reading comprehension yielded no differences between CHH (N = 108) and CNH (N = 62) except for reading comprehension for the moderately severe CHH. Reading achievement in CHH was found to exceed predictions based on prereading performance. This resilience was associated with gains in oral language during the early school years. PMID- 30298912 TI - The evolution of epigenetically mediated adaptive transgenerational plasticity in a subdivided population. AB - Transgenerational plasticity (TGP) occurs when offspring exhibit plasticity in traits induced by the environments experienced by their parents, and represents a nongenetic mechanism of inheritance. Evidence that traits can be transmitted to future generations by means other than genetic inheritance has caused a surge of interest in epigenetic inheritance, but evidence for epigenetic modifications being both adaptive and heritable remains scarce. What features would make a species most prone to evolve a system of epigenetically mediated adaptive TGP? Here, we use population-genetic models modified to include epigenetic induction and inheritance to investigate if and when epigenetically mediated adaptive TGP would be expected to evolve for a population subdivided between two habitats connected by migration. We show that differences in the direction of selection between the two habitats drives the evolution of epigenetically mediated adaptive TGP. With low migration, the strength of indirect selection in favor of epigenetically mediated adaptive TGP increases with migration rate. Yet, with higher migration, the opposite trend is observed. We predict that species subdivided between habitats that differ in the direction of selection with moderate migration rates between the habitats would be most likely to evolve epigenetically mediated adaptive TGP if costs of producing such systems are not too high. PMID- 30298913 TI - A genotypic trade-off between constitutive resistance to viral infection and host growth rate. AB - Genotypic trade-offs are fundamental to the understanding of the evolution of life-history traits. In particular, the evolution of optimal host defense and the maintenance of variation in defense against infectious disease is thought to be underpinned by such evolutionary trade-offs. However, empirical demonstrations of these trade-offs that satisfy the strict assumptions made by theoretical models are rare. Additionally, none of these trade-offs have yet been shown to be robustly replicable using a variety of different experimental approaches to rule out confounding issues with particular experimental designs. Here, we use inbred isolines as a novel experimental approach to test whether a trade-off between viral resistance and growth rate in Plodia interpunctella, previously demonstrated by multiple selection experiments, is robust and meets the strict criteria required to underpin theoretical work in this field. Critically, we demonstrate that this trade-off is both genetic and constitutive. This finding helps support the large body of theory that relies on these assumptions, and makes this trade-off for resistance unique in being replicated through multiple experimental approaches and definitively shown to be genetic and constitutive. PMID- 30298914 TI - Open or close the door to the outgroup? Diversity beliefs moderate the impact of group boundary permeability on attitudes toward the outgroup. AB - The present research investigated the moderating role of diversity beliefs with the aim of reconciling inconsistent findings regarding the impact of group boundary permeability on attitudes toward outgroup. In Study 1, all variables were measured with self-report scales completed by Chinese participants. In Study 2, diversity beliefs were manipulated by randomly assigning Chinese participants to a high or low diversity belief condition. In Study 3, we replicated the moderating model with American participants. Results of all three studies indicated that diversity beliefs moderated the relationship between group boundary permeability and attitudes toward outgroup. Individuals with high diversity beliefs held more positive attitudes toward the outgroup when the group boundary was permeable (vs. impermeable). Conversely, individuals with low diversity beliefs held more negative attitudes toward the outgroup when the group boundary was permeable (vs. impermeable). These findings suggest that when the inflow of the outgroup members is inevitable, attitudes toward the outgroup may be effectively improved by increasing diversity beliefs. PMID- 30298911 TI - Immune cells in the tumour: new routes of retinoids for chemoprevention and chemotherapeutics. AB - Retinoids, vitamin A and its natural and synthetic analogues have various functions, including being involved in cell proliferation and differentiation and participating in the formation of vertebrate morphology. In addition, they may activate certain tumour suppressor genes that then act as tumour inhibitors. In the past decades, retinoids have been regarded as promising chemotherapeutic and chemopreventive agents; however, their mechanisms are still not fully understood. Immune cells that participate in or are associated with the immune response play vital roles in the initiation and development of many cancers. Interestingly, recent studies have demonstrated that retinoids can also exert various effects on immune cells including macrophages, T cells and dendritic cells in tumour tissues to execute anti-tumour actions, providing new insights into chemoprevention and chemotherapeutics. In this review, we focus on the effects of retinoids on immune cells in the tumour, which may provide new approaches for antineoplastic strategies. PMID- 30298915 TI - Accuracy of anogenital distance and anti-Mullerian hormone in the diagnosis of endometriosis without surgery. AB - OBJECTIVE: To assess the predictive ability of a combination of anogenital distance (AGD) and anti-Mullerian hormone (AMH) to diagnosis the presence of endometriosis without surgery. METHODS: The present study included women diagnosed with endometriosis and a control group who attended the "Virgen de la Arrixaca" University Hospital, Murcia, Spain, between September 1, 2014, and May 31, 2015. Serum concentrations of AMH were measured, and two AGD measurements were obtained: from the anterior clitoral surface to the upper verge of the anus (AGDAC ), and from the posterior fourchette to the upper verge of the anus (AGDAF ). Data were assessed by receiver operator characteristic (ROC) curves. RESULTS: Women in the endometriosis group (n=57) had significantly shorter AGDAF (22.8 +/- 4.6 vs 27.2 +/- 5.7 mm; P<0.001) and lower AMH (2.2 +/- 2.5 vs 3.3 +/- 1.9 ng/mL; P<0.003) compared with the control group (n=93). Women with serum AMH below the clinical cut-off (1 ng/mL) were 17.40-times more likely to have endometriosis (95% confidence interval [CI] 5.64-53.82). The area under the ROC curve of combined AMH and AGDAF was 0.77 (95% CI 0.70-0.85). CONCLUSION: The model for predicting endometriosis on the basis of AMH and AGD could be useful for clinicians and epidemiologists to improve diagnosis and prognosis of this condition. PMID- 30298916 TI - PTSD and the influence of context: The self as a social mirror. AB - The principal accepted models of posttraumatic stress disorder (PTSD) are based on both memory processing and biological/brain changes occurring when one's life or well-being is threatened. It is our thesis that these models would be greatly informed by community studies indicating that PTSD is predicted to a greater extent by earlier life experience and experiences that occur distant from the threatening event. These findings suggest posttraumatic responding is best conceptualized through the lens of the self-in-context, as opposed to imprinting that results from a given event at a given time. Moreover, studies of non-Western populations often do not express trauma as PTSD, or at least not primarily as PTSD, which argues against specific neural or memory encoding processes, but rather for a more plastic neural process that is shaped by experience and how the self develops in its cultural context, as a product of a broad array of experiences. We posit that fear and emotional conditioning as well as the ways traumas are encoded in memory are only partial explanatory mechanisms for trauma responding, and that issues of safety and harm, which are long term and developmental, are the common and principal underpinnings of the occurrence of posttraumatic distress, including PTSD.

PMID- 30298921 TI - Context-dependent interactions between pathogens and a mutualist affect pathogen fitness and mutualist benefits to hosts. AB - Plants and animals host many microbial symbionts, including both pathogens and mutualists. However, most experimental studies include only one symbiont, and few examine interactions of more than two microbes with their host. Here, we examined whether coinfection with two pathogens causes a synergistic reduction in the benefits that hosts receive from a microbial mutualist. We also measured the effects of a microbial mutualist on the within- and between-host competition between coinfecting pathogens. We manipulated the presence of Clover yellow vein virus (ClYVV), Bean common mosaic virus (BCMV), rhizobia bacteria, and nitrogen fertilizer in common beans (Phaseolus vulgaris). We found asymmetric, context dependent interactions among the three microbial symbionts and their host. Coinfection with both viruses led to greater than additive negative effects on the amount of nitrogen that plants received from rhizobia. Rhizobia colonization decreased immune signaling in singly infected plants, but not in coinfected plants. Compared to single ClYVV infection, ClYVV reached higher concentrations within hosts coinfected with BCMV, but only in the presence of rhizobia. Coinfection increased BCMV vertical transmission rates for plants without supplemental nitrogen, but overall vertical transmission opportunities were not affected due to reduced seed production. Examining interactions between multiple microbes sharing a host can reveal important insights about nutrient cycling, disease severity, and pathogen epidemiology. PMID- 30298922 TI - How do international lawyers handle facts? The role of folk sociological theories at the International Criminal Court. AB - The International Criminal Court (ICC) investigates international crimes committed in different parts of the world. Earlier scholarly analysis of the work performed by the ICC judges has pointed out that judges often lack cultural and national understanding of the local norms and customs of regions where defendants come from. This article treats this lack of contextual knowledge displayed by the court as a case of structural ignorance rather than an aberration to be 'exposed' or censured. International lawyers indeed must ground their legal narratives with plausible sociological explanations of contextual elements to overcome their lack of familiarity with the field and the scarcity of their investigative resources. By uncovering the role of 'folk sociological theories' (FSTs) in the establishment of facts in a court context, this article addresses the debate over the efficiency of international criminal justice by highlighting the need to bring historical truth back in. The empirical evidence is based on several years of participant observation in the ICC during the trials against Mathieu Ngudjolo and Germain Katanga, two militiamen from the Democratic Republic of Congo (DRC). PMID- 30298923 TI - Dietary material properties shape cranial suture morphology in the mouse calvarium. AB - Cranial sutures are fibrous connective tissue articulations found between intramembranous bones of the vertebrate cranium. Growth and remodeling of these tissues is partially regulated by biomechanical loading patterns that include stresses related to chewing. Advances in oral processing structure and function of the cranium that enabled mammalian-style chewing is commonly tied to the origins and evolution of this group. To what degree masticatory overuse or underuse shapes the complexity and ossification around these articulations can be predicted based on prior experimental and comparative work. Here, we report on a mouse model system that has been used to experimentally manipulate dietary material properties in order to investigate cranial suture morphology. Experimental groups were fed diets of contrasting material properties. A masticatory overuse group was fed pelleted rodent chow, nuts with shells, and given access to cotton bedding squares. An underuse group was deprived of cotton bedding as well as diverse textured food, and instead received gelatinized food continuously. Animals were raised from weaning to adulthood on these diets, and sagittal, coronal and lambdoid suture morphology was compared between groups. Predicted intergroup variation was observed in mandibular corpus size and calvarial suture morphology, suggesting that masticatory overuse is associated with jaw and suture growth. The anterior region of the sagittal suture where it intersects with the coronal suture (bregma) showed no effect from the experiment. The posterior sagittal suture where it intersects with the lambdoid sutures (lambda) was more complex in the overuse group. In other words, the posterior calvarium was responsive to dietary material property demands while the anterior calvarium was not. This probably resulted from the different strain magnitudes and/or strain frequencies that occurred during overuse diets with diverse material properties as compared with underuse diets deprived of such enrichment. This work highlights the contrasting pattern of the sutural response to loading differences within the calvarium as a result of diet. PMID- 30298925 TI - The strength of sex-specific selection in the wild. AB - Anisogamy predisposes the sexes to very different patterns of selection on shared traits. Selective differences between the sexes may manifest as changes in the direction or strength of selection acting on shared phenotypes. Although previous studies have found evidence for widespread differences in the direction of selection between the sexes, surprisingly little is known regarding potential differences in the magnitude of selection and whether such differences might be confined to specific components of fitness. We conducted a meta-analysis using 865 estimates of phenotypic selection from wild populations to characterize sex differences in the strength of selection and to ask whether different components of fitness exhibit differences in sex bias in the strength of selection. Overall, consistent with past results, we find evidence of male bias in the strength of selection, driven primarily by components of fitness related to mating success and we discuss several evolutionary implications. PMID- 30298924 TI - The Impact of Healthcare-Associated Methicillin-Resistant Staphylococcus aureus Infections on Postdischarge Health Care Costs and Utilization across Multiple Health Care Systems. AB - OBJECTIVE: To measure how much of the postdischarge cost and utilization attributable to methicillin-resistant Staphylococcus aureus (MRSA) health care associated infections (HAIs) occur within the US Department of Veterans Affairs (VA) system and how much occurs outside. DATA SOURCES/STUDY SETTING: Health care encounters from 3 different settings and payment models: (1) within the VA; (2) outside the VA but paid for by the VA (purchased care); and (3) outside the VA and paid for by Medicare. STUDY DESIGN: Historical cohort study using data from admissions to VA hospitals between 2007 and 2012. METHODS: We assessed the impact of a positive MRSA test result on costs and utilization during the 365 days following discharge using inverse probability of treatment weights to balance covariates. PRINCIPAL FINDINGS: Among a cohort of 152,687 hospitalized Veterans, a positive MRSA test result was associated with an overall increase of 6.6 (95 percent CI: 5.7-7.5) inpatient days and $9,237 (95 percent CI: $8,211-$10,262) during the postdischarge period. VA inpatient admissions, Medicare reimbursements, and purchased care payments accounted for 60.6 percent, 22.5 percent, and 16.9 percent of these inpatient costs. CONCLUSIONS: While most of the excess postdischarge health care costs associated with MRSA HAIs occurred in the VA, non-VA costs make up an important subset of the overall burden. PMID- 30298926 TI - Bond paths between distant atoms do not necessarily indicate dominant interactions. AB - The goal of the article is to revive discussion on the interpretation of bond paths linking distant atoms, particularly tracing weak interactions in dimers. According to the Pendas' concept of privileged exchange channel, a bond path is formed between this pair of competing atoms, which is associated with larger value of the exchange energy. We point out that, due to the short-range nature of the exchange energy, bond paths linking distant atoms clearly become doubtful indicators of dominant intermolecular interactions, particularly if some other characteristics (geometric, spectroscopic, based on electrostatic parameters, etc.) indicate other intermolecular interactions as dominant. Several such cases are thoroughly investigated. We show that electrostatic parameters are much more reliable indicators of dominant intermolecular interactions than bond paths. Then, we pay attention that the presence of ("unexpected", i.e., not necessarily indicating dominant intermolecular interactions) bond paths between pairs of atoms featuring highly expanded charge distributions can be easily explained by visual exploration of isodensity contour plots. As always pointing in the direction of the steepest increase, the gradient vector of the electron density favors areas of its high values gaining higher exchange energy, yet being blind to highly electron deficient areas nearby, which, however, can quite often be involved in dominant intermolecular interactions as strongly suggested by many other bonding analysis. We also suggest that an interatomic component of Hellmann Feynman force would most likely be the most reliable indicator of attractive or repulsive character of individual interatomic interaction.

AB - BACKGROUND/AIM: Assessment of cognitive function in people with neurosychiatric disorders can be challenging, due to behavioural and psychiatric symptomatology. The Behavioural Assesment Tool for Cognition and Higher Functioning (BATCH) is a validated observational tool that complements formal cognitive testing in this patient population. This study aimed to determine the capacity of the BATCH as a predictive tool for discharge planning. METHOD: BATCH scores for 330 consecutive admissions for assessment to a specialist neuropsychiatry unit between 2007 and 2015 were analysed. The variables of interest included discharge destination, diagnosis, length of stay, age at discharge and BATCH scores (both subdomain and total). Significant predictors of discharge destination were identified using logistic regression analysis. RESULTS: After adjusting for age at discharge, three variables were found to be significant predictors of discharge destination length of stay, diagnosis, and BATCH total score. The odds of being discharged to a destination other than home decreased by 3% for each additional BATCH total score unit. The length of stay remained a significant predictor of discharge destination when adjusting for BATCH total score, age at admission and diagnosis. CONCLUSION: BATCH total scores, but not subdomain scores, were predictive of discharge destination, along with the patients' length of stay and diagnosis. Knowledge of this relationship may guide clinical discharge planning, when working with the complex needs of this group of patients. A larger study is indicated to determine the range and cut-off scores for discharge destinations other than home. PMID- 30298928 TI - Longer storage of red blood cells does not affect mortality in transfused liver transplant recipients. AB - BACKGROUND: The characteristics of red blood cell (RBC) products change after 2 weeks of cold storage. It is unclear whether older RBCs affect mortality after liver transplantation. This retrospective cohort study aimed to evaluate the association between the age of transfused RBCs and death after living donor liver transplantation (LDLT). STUDY DESIGN AND METHODS: Of 200 recipients who underwent LDLT, 118 who received RBCs with a mean storage duration of less than 10 days (shorter storage group) were compared with 82 with an RBC mean storage duration of more than 14 days (longer storage group). Key exclusion criteria were transfusion of very fresh RBCs stored for less than 4 days and transfusion of old RBCs in recipients of the shorter storage group. The primary outcome was posttransplant overall death. Survival analysis was performed using the Cox model. RESULTS: Mean RBC storage duration was 7 days in the shorter storage group and 17 days in the longer storage group. Death probability at 1, 2, and 5 years posttransplant was 5.1%, 7.6%, and 13.6% in the shorter storage group, respectively, and 6.1%, 8.5%, and 13.5% in the longer storage group. Death risk was comparable between the two groups in univariable (hazard ratio [HR] 1.00, 95% confidence interval [CI], 0.47-2.16, p = 0.991) and multivariable (HR 1.07, 95% CI, 0.46-2.50, p = 0.882) analyses. Graft failure risk was also comparable (HR 1.04, 95% CI, 0.50-2.18, p = 0.916). Hepatocellular carcinoma recurrence probability at 1, 2, and 5 years was 10.8%, 15.4%, and 23.1%, respectively, in the shorter storage group and 11.4%, 15.9%, and 20.7% in the longer storage group (HR 0.84, 95% CI, 0.37-1.89, p = 0.670). No significant differences were observed regarding graft regeneration/function, vascular/biliary complications, acute kidney injury, surgical site infection, or rejection (p > 0.05). CONCLUSIONS: No evidence was found that transfusion of old RBCs contributes to death after LDLT. PMID- 30298929 TI - What are the attributes of excellence in an acute practice occupational therapist? AB - BACKGROUND/AIM: There is anecdotal recognition within the profession that novice occupational therapists who perform well at interview do not necessarily make the best practising clinicians. Further anecdotal evidence suggests that it is difficult to tell (at interview) which occupational therapists will follow which path and whether further training can achieve excellence in existing staff. What is it that makes the difference? What attributes do those truly 'excellent' clinicians have that makes them better than others? METHOD: A two-round Delphi survey was utilised and 18 expert occupational therapists were purposively recruited from Perth's three adult tertiary hospitals. Panellists rated and ranked sixteen possible attributes that could comprise excellence in an acute practice occupational therapist. RESULTS: The final order of importance (from most to least) of the 16 possible attributes of excellence was determined. Communication, Self-management and Critical Thinking were found to be the three most important attributes, whereas Humility was considered the least important attribute. All attribute rankings achieved at least a low level of consensus. CONCLUSION: We now have a much clearer picture of what excellence looks like in the acute practice setting, giving managers a new understanding. There is now the possibility of integrating this information into both the recruitment of new staff and the professional development of existing staff. In this way we can move forward to a future that includes the active development of occupational therapy excellence in ways that were not possible before these results were available. PMID- 30298930 TI - Internationally educated occupational therapists transitioning to practice in Canada: A qualitative study. AB - BACKGROUND/AIM: While internationally educated occupational therapists (IEOTs) may assist Western countries in addressing workforce shortages, their transition to practice can be difficult. Provincial and national levels of government in Canada have funded initiatives to address the barriers experienced by IEOTs. The purpose of this study is to identify the key forces shaping the experiences of IEOTs transitioning to practice in Canada. METHODS: An interpretive description approach was taken to interview 11 IEOTs who graduated from the Occupational Therapy Examination and Practice Preparation (OTepp) program. Data analysis was guided by the theoretical scaffolding of the occupational therapy profession. Two team members, who are also occupational therapists, developed codes and categories independently and then through discussion reached a higher level of interpretation. RESULTS: The experiences of IEOTs in Canada were shaped by two key forces: Realising that more than exam preparation is required and the impact of previous person, environment and occupation transactions. Participants underestimated their learning needs related to their transition to Canadian practice. As they engaged in the OTepp program, they realised that their learning extended beyond that required for the national certification exam. Also, the extent to which the participant (person), previous context (environment) and previous practice (occupation) were similar to Canadian therapists, influenced IEOTs' performance in OTepp and their overall transition to practice. The Person Environment-Occupation (PEO) model provided a framework to contextualise this theme. CONCLUSION: IEOTs will benefit from individualised learning needs assessments and education plans to address their specific needs. At an international level, the occupational therapy profession must engage in dialogue about the differences between education programs and the resulting implications for the profession. More research is also needed to understand the experiences of IEOTs who withdraw from or do not engage in formal supports.

AB - Some plants of Buddleja genus possessed antimicrobial activity. In this study, the antibacterial activities of nine compounds from Buddleja albiflora were evaluated against Listeria monocytogenes, Staphyloccocus aureus, Escherichia coli and Pseudomonas aeruginosa, either alone or in combination with Erythromycin (Ery), Gentamicin (Gen) and Ampicillin (Amp). Checkerboard assay demonstrated that Kumatakenin elicited synergistic effects with all three antibiotics, and chrysin displayed synergistic effect with Ery against L. monocytogenes. Further experiments showed that the synergy effect was sufficient to eradicate biofilms formed by L. monocytogenes. Thus, our data highlighted that the combinations of secondary metabolites from B. albiflora and specific antibiotics were useful for the treatment of pathogens, which might help prevent the spread of antibiotic resistance through improving antibiotic effectiveness.

AB - OBJECTIVES: To examine any change over time in the association between deprivation and caries experience between 2003 and 2013 in a nationally representative sample of UK children. METHODS: Data from UK Children's Dental Health Surveys, 2003 and 2013, were used. The target population was 5-, 8-, 12- and 15-year-olds. A total of 9604 children in 2003 and 9866 in 2013 were included in the surveys. Outcome variables were any active caries, caries experience and total number of carious teeth. Family socio-economic position (SEP) or deprivation level was measured at school level using eligibility for free school meals (FSM) to identify children from low-income families. Incidence rate ratios (IRR) and pooled standardized incidence rates ratios were calculated to measure dichotomous outcome variables by year, age group and status of deprivation. The study continuous outcome was modelled using a zero-inflated Poisson regression while the dichotomous outcomes were modelled using logistic regressions. The multivariable analyses were run by age groups accounting for year, sex and deprivation status. RESULTS: The percentage of those identified as deprived was significantly higher in 2013 (35.8% in 2013 vs 26.0% in 2003, P < 0.001). Among both deprived and non-deprived children, the prevalence of any active caries significantly dropped over the years, observed in all age groups. Comparing 2013 with 2003 and accounting for sex, deprivation level, "any active caries," "any caries experience" and "total number of carious teeth" significantly dropped were observed in all age groups. Comparing the years, the association of deprivation with caries outcomes mostly remained the same or decreased. This decrease was predominantly seen in "any caries experience." Only among the 5-year-olds, did the association between deprivation and total number of carious teeth over the years significantly increase. For all age groups, the likelihood of "any active caries" and "total number of carious teeth" by deprivation remained the same comparing the two points in time: 2003 and 2013. However, irrespective of year, deprivation was significantly associated with caries observed in all age groups. CONCLUSION: In the UK, the prevalence of active dental caries and caries experience has decreased in the period between 2003 and 2013. Similarly, the likelihood of having dental caries by deprivation in 2013 was predominantly lower than that observed in 2003. PMID- 30298933 TI - A path integral molecular dynamics study on intermolecular hydrogen bond of acetic acid-arsenic acid anion and acetic acid-phosphoric acid anion clusters. AB - We apply ab initio path integral molecular dynamics simulation employing omegaB97XD as the quantum chemical calculation method to acetic acid-arsenic acid anion and acetic acid-phosphoric acid anion clusters to investigate the difference of the hydrogen bond structure and its fluctuation such as proton transfer. We found that the nuclear quantum effect enhanced the fluctuation of the hydrogen bond structure and proton transfer, which shows treatment of the nuclear quantum effect was essential to investigate these systems. The hydrogen bond in acetic acid-arsenic acid anion cluster showed characters related to low barrier hydrogen bonds, while acetic acid-phosphoric acid anion cluster did not. We found non-negligible distinction between these two systems, which could not be found in conventional calculations. We suggest that the difference in amount of atomic charge of the atoms consisting the hydrogen bond is the origin of the difference between acetic acid-arsenic acid and acetic acid-phosphoric acid anion cluster.

AB - Epidermal growth factor receptor (EGFR) is a prototypical cell-surface receptor that plays a key role in the regulation of cellular signaling, proliferation and differentiation. Mutations of its kinase domain have been associated with the development of a variety of cancers and, therefore, it has been the target of drug design. Single amino acid substitutions (SASs) in this domain have been proven to alter the equilibrium of pre-existing conformer populations. Despite the advances in structural descriptions of its so-called active and inactive conformations, the associated dynamics aspects that characterize them have not been thoroughly studied yet. As the dynamic behaviors and molecular motions of proteins are important for a complete understanding of their structure-function relationships we present a novel procedure, using (or based on) normal mode analysis, to identify the collective dynamics shared among different conformers in EGFR kinase. The method allows the comparison of patterns of low-frequency vibrational modes defining representative directions of motions. Our procedure is able to emphasize the main similarities and differences between the collective dynamics of different conformers. In the case of EGFR kinase, two representative directions of motions have been found as dynamics fingerprints of the active conformers. Protein motion along both directions reveals to have a significant impact on the cavity volume of the main pocket of the active site. Otherwise, the inactive conformers exhibit a more heterogeneous distribution of collective motions. (c) 2018 Wiley Periodicals, Inc.

AB - BACKGROUND/AIM: Limited research has been available to support the use of the Kettle Test in a subacute rehabilitation setting with patients diagnosed with a variety of medical conditions. The Kettle Test is an occupation based performance measure designed to detect cognitive processes and function. The aim of this research was to measure the correlation between three cognitive tests, the Mini Mental State Examination (MMSE), Cognitive Functional Independence Measure (Cognitive FIM) and the Kettle Test. Secondly, to assess the efficacy of these tests in predicting functional outcomes via the motor subscale of the Functional Independence Measure (mFIM). METHODS: A prospective single-centre cohort study in a subacute rehabilitation setting of 97 patients. RESULTS: Correlation coefficients between the tests were statistically significant and moderately strong, with values ranging from 0.593 to -0.589. Significant positive correlations were seen between admission MMSE, Cognitive FIM and the mFIM and significant negative correlations between Kettle Test scores and the mFIM. The Kettle Test score had a stronger relationship with mFIM (r = -0.40; P < 0.01) compared to the Cognitive FIM (r = 0.33; P < 0.01) and MMSE (r = 0.26; P < 0.05). The Kettle Test variance is significantly associated with the MMSE and Cognitive FIM at admission and discharge measures. Modelling identified that age and gender significantly contribute to this relationship. When adjusted for age and gender the MMSE and Cognitive FIM both explained the 47% of the variance at discharge. CONCLUSION: There were statistically significant inter-test correlations between the MMSE, Cognitive FIM and Kettle Test. The Kettle Test had the strongest relationship to patient functional outcomes. PMID- 30298938 TI - Corrigendum for Crovetto, Figueras, Triunfo, et al. (2014) https://doi.org/10.1002/pd.4519. PMID- 30298937 TI - Numerical Approach to Study the Behavior of an Artificial Ventricle: Fluid Structure Interaction Followed By Fluid Dynamics With Moving Boundaries. AB - Heart failure is a progressive and often fatal pathology among the main causes of death in the world. An implantable total artificial heart (TAH) is an alternative to heart transplantation. Blood damage quantification is imperative to assess the behavior of an artificial ventricle and is strictly related to the hemodynamics, which can be investigated through numerical simulations. The aim of this study is to develop a computational model that can accurately reproduce the hemodynamics inside the left pumping chamber of an existing TAH (Carmat-TAH) together with the displacement of the leaflets of the biological aortic and mitral valves and the displacement of the pericardium-made membrane. The proposed modeling workflow combines fluid-structure interaction (FSI) simulations based on a fixed grid method with computational fluid dynamics (CFD). In particular, the kinematics of the valves is accounted for by means of a dynamic mesh technique in the CFD. The comparison between FSI- and CFD-calculated velocity fields confirmed that the presence of the valves in the CFD model is essential for realistically mimicking blood dynamics, with a percentage difference of 2% during systole phase and 13% during the diastole. The percentage of blood volume in the CFD simulation with a shear stress above the threshold of 50 Pa is less than 0.001%. In conclusion, the application of this workflow to the Carmat-TAH provided consistent results with previous clinical studies demonstrating its utility in calculating local hemodynamic quantities in the presence of complex moving boundaries.

AB - Early life stage white sturgeon are sensitive to copper with adverse behavioral responses observed during previous studies. The objectives of the present study were to quantify the effects of copper exposure on white sturgeon swimming and feeding behaviors and determine their time to response. Larval sturgeon (1-2, 28 or 35 days post hatch) were exposed to copper (0.5-8 ug/L) for 4-14 days. Abnormal behavioral changes were observed within the first few days of exposure including loss of equilibrium and immobilization. Digital video tracking software revealed decreased swimming activity with increasing copper concentration. Significant changes in behavior and mortality occurred at concentrations of copper between 1-8 ug/L. Juvenile white sturgeon, 58 days post hatch, exposed to 12 ug/L copper consumed 37-60% less food than controls after 3 days of exposure. Our results indicate that behavioral endpoints were more sensitive than some standard toxicity test endpoints and can be effectively expand the sensitivity of standard toxicity tests for white sturgeon. Swimming behavior was impaired to the extent that survival in the field would likely be jeopardized. Such data would provide managers a useful metric for characterizing the risks of copper contamination to white sturgeon. This article is protected by copyright. All rights reserved. PMID- 30298942 TI - Is it justifiable to pool Chironomus species in trace element contamination studies? AB - Larvae of the insect Chironomus (Chironomidae, Diptera) have great potential for estimating the bioavailability of sedimentary trace elements since they are common in fine sediments and tolerate high concentrations of these contaminants. Their use as biomonitors is limited by the fact that they are difficult to identify to species, and species can differ in their trace element concentrations. To determine if pooling species would compromise their use as trace element biomonitors, we identified species of Chironomus larvae collected from 22 lakes and measured their concentrations of 9 trace elements. We found that the concentrations of As, Ba, Co, Cu, Mn and Ni did not generally differ between sympatric Chironomus species, which indicates that they could be pooled for analyses of these trace elements. In contrast, we found that Cd, Se and Zn concentrations differed between species living at the same site according to their feeding behavior, that is, Chironomus species feeding on oxic sediments tended to have higher Cd and Zn concentrations, whereas those feeding on deeper anoxic sediments had higher Se concentrations. Since Se and Zn concentrations in sympatric Chironomus species usually differed by only a factor of two, separating species based on their feeding behavior might not be as crucial as for Cd if larval Se and Zn concentrations vary greatly from site to site.

AB - AIMS: To perform a systematic review of studies reporting the outcomes of AMS-800 artificial urinary sphincter (AUS) implantation in female patients with stress urinary incontinence (SUI) resulting from intrinsic sphincter deficiency (ISD). METHODS: A systematic literature search of the Medline and Embase databases was performed in June 2018 in accordance with the PRISMA statement. No time limit was used. The protocol was registered in PROSPERO (CRD42018099612). Study selection and data extraction were performed by two independent reviewers. RESULTS: Of 886 records screened, 17 were included. All were retrospective or prospective non comparative case series. One study reported on vaginal AUS implantation, 11 on open AUS implantation, two on laparoscopic AUS implantation, two on robot assisted AUS implantation and one compared open and robot-assisted implantations. The vast majority of patients had undergone at least one anti-incontinence surgical procedure prior to AUS implantation (69.1-100%). The intraoperative bladder neck injury rates ranged from 0% to 43.8% and the intraoperative vaginal injury rates ranged from 0 to 25%. After mean follow-up periods ranging from 5 to 204 months, the complete continence rates ranged from 61.1% to 100%. The rates of explantation, erosion and mechanical failure varied from 0% to 45.3%, 0% to 22.2% and 0% to 44.1%, respectively. CONCLUSIONS: AMS-800 AUS can provide excellent functional outcomes in female patients with SUI resulting from ISD but at the cost of a relatively high morbidity. High level of evidence studies are needed to help better define the role of AUS in the female SUI armamentarium.

AB - BACKGROUND: There is need for deeper understanding of the processes by which suicidal thoughts lead to action. Examination of morbid ideation and the emotional sequelae of such ideation that may feed suicide ideation (SI) and attempts (SA) have been limited. METHOD: Adult psychiatric outpatients (N = 385) were administered the Response to Morbid Ideation Questionnaire (RMI-Q) and measures of SI, suicidal thoughts and behaviors (STB), and other psychiatric symptom severity. We examined (1) incidence and prevalence in mentation of morbid ideations and emotional responses to these ideations, (2) differences in emotional responses between individuals of varying levels of suicide history, and (3) the relationships of different types of morbid ideations and emotional responses with concurrent SI and symptom severity. RESULTS: Morbid ideation was reported by 87.5% of participants and associated with lifetime and concurrent levels of SI/STB. Calm/relieved emotional responses were associated with lifetime and concurrent levels of SI/STB, while negative-valence responses to morbid ideations were associated with concurrent severity of psychopathology. CONCLUSIONS: Our results suggest that the role of morbid ideation and its emotional sequelae in the development of suicidal motivation and action deserves further attention and may be a treatment target for suicide risk reduction. PMID- 30298944 TI - Copper toxicity in Bristol Bay headwaters: Part 2-olfactory inhibition in low hardness water. AB - We investigated the olfactory toxicity of copper (Cu) to rainbow trout in low hardness (27 mg/L as CaCO3 ) water formulated in the laboratory over a 120-h period using a flow-through design. The fish's response to an alarm cue (e.g., reduction in activity) was recorded to determine the exposure concentrations and durations that inhibited olfactory detection of the cue after 3, 24, 48, and 96 h of Cu exposure and after 24 h of clean water recovery following the 96-h exposure period. Exposures were conducted with a range of Cu concentrations from 0.13 (control) to 7.14 MUg Cu/L (dissolved Cu). We observed a dose-dependent response in olfactory inhibition with a 20% reduction in the probability of responding to the alarm cue, relative to controls, at 2.7 and 2.4 MUg Cu/L after 24 or 96 h of exposure, respectively. Olfactory inhibition manifested between 3 and 24 h of exposure. Our 24- and 96-h 20% olfactory inhibition estimates fell between the criteria derived using the biotic ligand model (BLM; criterion maximum concentration [CMC] and criterion continuous concentration [CCC] values were 0.63 and 0.39 MUg Cu/L, respectively) and water hardness-based criteria (CMC and CCC values were 3.9 and 2.9 MUg Cu/L, respectively). Therefore, the hardness-based criteria do not appear to be protective and the BLM-derived criteria do appear to be protective against Cu-induced olfactory inhibition given our test water chemistry. Neither the hardness-based criteria nor the BLM-derived criteria appear to be protective against our estimated Cu behavioral avoidance response concentrations at 24- and 96-h exposures (0.54 and 0.50 MUg Cu/L, respectively).

AB - OBJECTIVE: To examine occupational and personal suicide exposure among Law Enforcement Officers (LEOs) and related mental health outcomes. METHODS: Law Enforcement Officers (N = 813) completed an online survey about their suicide exposure, whether scenes stayed with them, and current symptoms of depression, anxiety, PTSD, and suicidal ideation. RESULTS: Almost all participants (95%) had responded to at least one suicide scene with an average of 30.90 (SD = 57.28) career suicide scenes and 2.17 in the last year (SD = 4.11). One in five (22%) reported a scene that they cannot shake or have nightmares about, and 42.5% reported one scene that stayed with them. Almost three fourths (73.4%) knew someone personally who had died by suicide. There was a significant association between high levels of occupational exposure to suicide and behavioral health consequences including PTSD, persistent thoughts of a suicide scene, and the inability to shake a scene. The inability to shake a scene and having a scene stick with them was associated with increased symptoms of depression, anxiety, PTSD, and suicidal ideation. CONCLUSIONS: LEOs experience a tremendous amount of exposure to suicide scenes and also have personal exposure. There is a need for training to mitigate the effect of these multiple traumas on their mental health. PMID- 30298946 TI - Genotype imputation accuracy in multiple equine breeds from medium- to high density genotypes. AB - Genotype imputation is now a key component of genomic analyses as it increases the density of available genotypes within a population. However, many factors can influence imputation accuracy. The aim of this study was to assess and compare the accuracy of imputation of high-density genotypes (Affymetrix Axiom Equine genotyping array, 670,806 SNPs) from two moderate-density genotypes (Illumina Equine SNP50 BeadChip, 54,602 SNPs and Illumina Equine SNP70 BeadChip, 65,157 SNPs), using single-breed or multiple-breed reference sets. Genotypes were available from five groups of horse breeds: Arab (AR, 1,207 horses), Trotteur Francais (TF, 979 horses), Selle Francais (SF, 1,979 horses), Anglo-Arab (AA, 229 horses) and various foreign sport horses (FH, 209 horses). The proportions of horses genotyped with the high-density (HD) chip in each breed group were 10% in AA, 15% in AR and FH, 30% in TF and 57% in SF. A validation set consisting of one third of the horses genotyped with the HD chip was formed and their genotypes deleted. Two imputation strategies were compared, one in which the reference population consisted only of horses from the same breed group as in the validation set, and another with horses from all breed groups. For the first strategy, concordance rates (CRs) ranged from 97.8% (AR) to 99.0% (TF) and correlations (r2) from 0.94 (AR) to 0.99 (TF). For the second strategy, CR ranged from 97.4% (AR) to 98.9% (TF) and r2 from 0.93 (AR) to 0.99 (TF). Overall, the results show a small advantage of within-breed imputation compared with multi breed imputation. Adding horses from different breed groups to the reference population does not improve the accuracy of imputation. Imputation provides an accurate means of combining data sets from different genotyping platforms, now necessary with the increasing use of the recently developed Affymetrix Axiom Equine genotyping array. PMID- 30298948 TI - Characterization of DNA double-strand break repair pathways in diffuse large B cell lymphoma. AB - Efficient DNA repair is indispensable for maintaining genomic integrity in humans. Cancer associated deletions and mutations are mainly due to misrepaired DNA double-strand breaks (DSBs). Classical nonhomologous end joining (c-NHEJ) and homologous recombination (HR) are two major DSB repair pathways in humans. An error prone, alternative NHEJ pathway that utilizes microhomology was also reported in cancer cells and to a lesser extent in normal cells. In the present study, we evaluated the efficiency of various DSB repair pathways in the most common lymphoma, the diffuse large B cell lymphoma (DLBCL). Here we show that DNA repair through c-NHEJ pathway is limited in SUDHL8, a cell line derived from a DLBCL patient. Unlike c-NHEJ, microhomology mediated end joining (MMEJ) was predominant at physiological temperature. Consistent with the observation, expression level of repair proteins such as LIGASE I, LIGASE III, PARP1, CtIP, and MRE11 was higher in DLBCL cells when compared to c-NHEJ proteins. Further, inhibition of LIGASE I or MRE11, led to reduction in the efficiency of MMEJ in DLBCL cells. Besides, HR-mediated DSB repair occurring through gene conversion was observed. Thus, our results reveal the predominance of MMEJ over c-NHEJ in repairing DSBs in DLBCL cells, while error-free repair through HR was also evident. PMID- 30298949 TI - Fluctuating operation development index of community health service centres in the Pudong new area of Shanghai: A continuous investigation. AB - BACKGROUND: Previous performance evaluations among community health service centres (CHSCs) have been mainly based on absolute indicators, while the operation index, a more comprehensive evaluation method, has been rarely used in evaluation. This study aimed to develop a set of operation index suitable for the evaluation of CHSCs in Pudong. METHODS: The operation index system, developed based on a literature review, focus group, and factor analysis, was applied to all 45 CHSCs in Pudong. The data were mainly derived from the Pudong Health Statistics Information System from 2010 to 2014. The analysis included a descriptive analysis, t tests, variance analysis, and repeated measures analysis of variance. RESULTS: Different aspects of the operation index showed different developing trends during 2010 to 2014. The overall operation, service operation, management condition, and comprehensive satisfaction index were significantly different in different years (P < 0.05). However, the differences in the development foundation index were not obvious (P > 0.05). Moreover, the regional factor and medical association influenced the performance of service operation index, and the informatization level affected the performance of overall operation and management condition index (P < 0.05), with different family GP programmes level affecting management condition index (P < 0.05). CONCLUSION: Changes in the management condition index led to fluctuations in overall operation in the CHSCs. Since regional factors, family GP programmes, and medical associations promoted the operation of CHSCs, we advocate a multi-dimensional evaluation combining horizontal performance appraisal and vertical index evaluation to focus on these factors. PMID- 30298950 TI - MR study of longitudinal variations in proximal femur 3D morphological shape and associations with cartilage health in hip osteoarthritis. AB - The goal of this study was to use quantitative MRI analysis to longitudinally observe the relationship between 3D proximal femur shape and hip joint degenerative changes. Forty-six subjects underwent unilateral hip MR imaging at three time points (baseline, 18 and 36 months). 3D shape analysis, hip cartilage T1rho /T2 relaxation time quantification, and SHOMRI MRI grading were performed at each time point. Subjects were grouped based on KL, SHOMRI, and HOOS pain scores. Associations between these score groupings, time, and longitudinal variation in shape, were analyzed using a generalized estimating equation. One way ANCOVA was conducted to evaluate change in shape as a predictor of the worsening of degenerative changes at 36 months. Our results demonstrated that subjects displayed an increase in the volume of the femoral head and neck (Mode 3) over time. This shape mode was significantly more prevalent in patients that reported pain. Longitudinal changes in this shape mode also served as borderline predictors of elevated T1rho values (p = 0.055) and of cartilage lesions (p = 0.068). Subjects showed a change in the Femoral Neck Anteversion angle (FNA) over time (Mode 6). This shape mode showed a significant interaction with the presence of cartilage lesions. The results of this study suggest that specific variations in bone shape quantified through 3D-MRI based Statistical Shape modeling show an observable relationship with hip joint compositional and morphological changes. The shapes observed lead to early degenerative changes, which may lead into OA, thus confirming the important role of bone shape changes in the pathogenesis of OA.

AB - This work reports a repurposing study of pyrazinoic acid (1) and methyl (2), ethyl (3) and 2-chloroethyl (4) ester derivatives with antimycobacterial activity, in assays against Trypanosoma cruzi. The compounds and benznidazole, the standard antitrypanosoma drug, were evaluated in concentrations ranging from 100 to 6.25 MUg/mL. The results showed that compounds 2 and 3 (EC50 = 182 and 447 MUM) significantly reduced the infection rate of the parasite into the mammalian cells at 100 MUg/mL (p < 0.05) in a similar way to benznidazole. In addition, all the compounds also significantly reduced the number of intracellular parasites (compound 1 at 50 MUg/mL, and compounds 2-4 at 100 MUg/mL, p < 0.05) in comparison to the control. Compounds 1 and 2 were more effective than benznidazole at 50 MUg/mL (p < 0.001). Moreover, compounds 1-4 did not show significant cytotoxicity against THP-1, J774, and HeLa cells (>1000 MUM), indicating that they possess considerable selectivity against the parasites. This report represents the first study of such compounds against T. cruzi, indicating the potential of pyrazinoates as antiparasitic agents. PMID- 30298953 TI - Assessing the effectiveness of advanced nurse practitioners undertaking home visits in an out of hours urgent primary care service in England. AB - AIM: To measure the effectiveness of advanced nurse practitioners (ANPs) against national quality requirements for out-of-hours (OOH) care, to compare ANP effectiveness with that of doctors working in the same service, and to evaluate the impact of ANPs on the service. BACKGROUND: There is little documented evidence of ANPs undertaking urgent home visits in the OOH setting. This study advances current knowledge of this aspect of the OOH service and makes recommendations for the management of the ANP urgent home visiting service. METHODS: Analysis of 1,539 ANP home-visit patient electronic case notes over a 12 month period, a focus group of eight GPs, and interviews with six ANPs. RESULTS: Advanced nurse practitioners are as effective as GPs in undertaking urgent home visits. Their documentation is more consistent and their refer-on rate to secondary care is less than that of GP colleagues. CONCLUSION: Advanced nurse practitioners can provide equivalent clinical outcomes to GPs when undertaking urgent home visits. IMPLICATIONS FOR NURSING MANAGEMENT: This study adds to the body of evidence for the positive impact of ANPs on OOH service delivery and managers can be assured that they are practising at a level that makes them effective and safe to undertake this role. PMID- 30298952 TI - IL-6 mediates ER expansion during hyperpolarization of alternatively activated macrophages. AB - Although recent evidence has shown that IL-6 is involved in enhanced alternative activation of macrophages toward a profibrotic phenotype, the mechanisms leading to their increased secretory capacity are not fully understood. Here, we investigated the effect of IL-6 on endoplasmic reticulum (ER) expansion and alternative activation of macrophages in vitro. An essential mediator in this ER expansion process is the IRE1 pathway, which possesses a kinase and endoribonuclease domain to cleave XBP1 into a spliced bioactive molecule. To investigate the IRE1-XBP1 expansion pathway, IL-4/IL-13 and IL-4/IL-13/IL-6 mediated alternative programming of murine bone marrow-derived and human THP1 macrophages were assessed by arginase activity in cell lysates, CD206 and arginase-1 expression by flow cytometry, and secreted CCL18 by ELISA, respectively. Ultrastructural intracellular morphology and ER biogenesis were examined by transmission electron microscopy and immunofluorescence. Transcription profiling of 128 genes were assessed by NanoString and Pharmacological inhibition of the IRE1-XBP1 arm was achieved using STF-083010 and was verified by RT-PCR. The addition of IL-6 to the conventional alternative programming cocktail IL-4/IL-13 resulted in increased ER and mitochondrial expansion, profibrotic profiles and unfolded protein response-mediated induction of molecular chaperones. IRE1-XBP1 inhibition substantially reduced the IL-6 mediated hyperpolarization and normalized the above effects. In conclusion, the addition of IL-6 enhances ER expansion and the profibrotic capacity of IL-4/IL-13 mediated activation of macrophages. Therapeutic strategies targeting IL-6 or the IRE1-XBP1 axis may be beneficial to prevent the profibrotic capacity of macrophages.

AB - The aim of this study was to analyse the characteristics of central venous catheters with brachial-implanted reservoirs and the complications associated with their use over a 4-years period. This observational study was carried out in an onco-haematological day hospital in Spain. Information was collected about 125 catheters inserted in patients requiring intravenous chemotherapy. There were more catheters implanted in women than men and the mean age was 58.6 years. Seventy of the implanted catheters were made of polyurethane and 55 of silicone. Left laterality prevailed with a mean catheter dwell-time of 347.1 days. A total of 164 complications were registered, 124 of them came from blood draws, where the most frequent complication was "inability to withdraw, ability to infuse". Forty complications were associated with the administration of treatments. Furthermore, there were 21 catheter removals, caused by several other complications different from those mentioned before. Statistically significant differences were found when associating types of catheters, laterality, blood draws and administration of treatments. Results showed how silicone ports would be more appropriate for patients who carry these types or ports than polyurethane because they reduce the number of complications causes by thrombosis.

Cardiovascular disorders are a field of application of these guidelines, but practical implementation is challenging due to the genetic disease heterogeneity and the complexity of information sources that need to be integrated. Decision support systems able to automate variant interpretation in the light of specific disease domains are demanded. We implemented CardioVAI (Cardio Variant Interpreter), an automated system for guidelines based variant classification in cardiovascular-related genes. Different omics-resources were integrated to assess pathogenicity of every genomic variant in 72 cardiovascular diseases related genes. We validated our method on benchmark datasets of high confident assessed variants, reaching pathogenicity and benignity concordance up to 83 and 97.08%, respectively. We compared CardioVAI to similar methods and analyzed the main differences in terms of guidelines implementation. We finally made available CardioVAI as a web resource (http://cardiovai.engenome.com/) that allows users to further specialize guidelines recommendations.

AB - AIM: There are minimal data to guide the continuing medical education (CME) of general paediatricians working in non-tertiary hospitals. The aim of this study was to determine the procedural and resuscitation skills required by non-tertiary paediatricians and the frequency with which these skills are utilised. METHODS: Over a 12-month period (December 2012 to December 2013), each of the 11 paediatricians involved in acute inpatient care at University Hospital Geelong (UHG) completed a weekly online survey regarding their inpatient clinical experience. This included procedures performed or directly supervised as well as their resuscitation involvement. RESULTS: Each of the 11 paediatricians who managed inpatients on a regular or semi-regular basis during the study period agreed to participate, and each completed all of the weekly surveys. There were seven UHG paediatricians with an inpatient appointment (each with a 0.27 full time equivalent (FTE) paediatrician workload) and four paediatricians providing inpatient cover on a locum basis. Over the course of 12 months, each 0.27 FTE paediatrician was, on average, involved in 11.3 neonatal, 1.7 infant and 2.4 child resuscitations and performed 0.9 intubations. CONCLUSIONS: Paediatricians working at non-tertiary hospitals are required to perform and supervise critical procedural and resuscitation skills but have limited opportunities to maintain proficiency in such skills. General paediatric training and consultant paediatrician CME programmes should ensure the acquisition and maintenance of the procedural and resuscitation skills required for the management of seriously ill children in non-tertiary acute care settings. PMID- 30298957 TI - Ventilatory constraints influence physiological dead space in heart failure. AB - NEW FINDINGS: What is the central question of this study? The goal of this study was to investigate the effect of alterations in tidal volume and alveolar volume on the elevated physiological dead space and the contribution of ventilatory constraints thereof in heart failure patients during submaximal exercise. What is the main finding and its importance? We found that physiological dead space was elevated in heart failure via reduced tidal volume and alveolar volume. Furthermore, the degree of ventilatory constraints was associated with physiological dead space and alveolar volume. ABSTRACT: Patients who have heart failure with reduced ejection fraction (HFrEF) exhibit impaired ventilatory efficiency [i.e. greater ventilatory equivalent for carbon dioxide ( PMID- 30298959 TI - The association between school holidays and unintentional fatal drowning among children and adolescents aged 5-17 years. AB - AIM: Children aged 5-17 years in Australia have one of the lowest unintentional fatal drowning rates. One possible explanation is the protective effect of formal schooling, reducing leisure time for exposure to water hazards. We examine differences in frequency and circumstances of drowning deaths in this age group between school holidays and school days in Australia. METHODS: A total population survey (2005-2014) of unintentional fatal drownings was extracted from the (Australian) Royal Life Saving National Fatal Drowning Database. Date of drowning incident and state of residence were used to determine if the drowning occurred during school days or school holidays (including public holidays). RESULTS: A total of 188 5-17 year-olds drowned during the study period. We found a statistically significant difference between drowning incidence during school holidays and school days, with relative risk (RR) of drowning on a holiday 2.40 times higher (confidence interval (CI): 1.82-3.18) than on a school day. This risk was similar for males (RR = 2.41; CI: 1.75-3.33) and females (RR = 2.38; CI: 1.33-4.27) but differs between children 5-9 years (RR = 3.05; CI: 1.98-4.72) and adolescents 10-17 years of age (RR = 2.02; CI: 1.38-2.93). CONCLUSIONS: Drowning rates among 5-17 year-olds are more than twice as high during holidays than on school days. Impact of school holidays was the strongest among younger children, visitors to the drowning location and in pools and inland waterways. Results were robust to alternative specifications excluding weekends and treating them as holidays. Prevention strategies may include counselling parents and care providers of the increased risk ahead of school holidays, education on drowning risk in the school curriculum and extra holidays for parents and care givers. PMID- 30298958 TI - Exploring children's experiences in community gambling venues: A qualitative study with children aged 6-16 in regional New South Wales. AB - ISSUE ADDRESSED: Community-based gambling venues provide a range of activities for children alongside adult products, such as gambling. However, there has been little examination of children's experiences with, and exposure to, a range of gambling and non-gambling activities within venues. METHODS: Visual sociology methods were used to measure unprompted recall, prompted recall, current use and intended adult use of activities in community gambling venues in 44 children who attended venues. Qualitative data were also collected to gain further insight into children's perceptions of the venue and the activities within. RESULTS: Children displayed high unprompted and prompted recall of gambling and nongambling activities within the venue. Children indicated positive perceptions of the venue overall. Just over half of the children (52.3%) reported current use of gambling activities in the venue. The large majority of the children indicated that they would attend community gambling venues as an adult (90.9%). CONCLUSION: This research provides a starting point in understanding the extent to which children are exposed to gambling products in community gambling venues. SO WHAT?: This research will be important for researchers, policy makers and practitioners in developing health promotion initiatives to prevent children from being exposed to gambling products in community settings. PMID- 30298960 TI - Healthcare professionals' perspectives on the prevalence, barriers and management of psychosocial issues in cancer care: A mixed methods study. AB - This cross-sectional mixed methods survey explores healthcare professionals' perspective on their management of cancer patients' psychosocial concerns, and barriers to integrate the psychosocial approach in their work. An invitation for participation was sent to 4,965 inpatient and outpatient working professionals, of which 583 responded (12% response rate), and 368 fully completed the survey. The majority of respondents does not use a systematic approach to discuss patients' psychosocial concerns, 37.5% use the general question "How are you?," and 65.0% spontaneously addresses various psychosocial aspects. Most psychosocial topics are "sometimes" or "regularly" discussed. Sexuality and return to work are rarely mentioned. About half of the respondents are convinced that they pay enough attention to the psychosocial well-being of cancer patients: by listening, engaging in a deeper conversation, providing advice and through referral. Mostly, patients are referred to a psychologist, a general practitioner, a social worker, a specialised nurse or a centre for well-being and mental health. The barriers experienced, when providing psychosocial support, can be attributed to the patients, to themselves or other healthcare professionals, and to policy restrictions. These barriers should be addressed in order to enable healthcare professionals to improve the integration of the psychosocial approach in cancer care. PMID- 30298962 TI - Knowledge, attitudes and practice of surgeons regarding nutritional support in CRS and HIPEC patients: Are we missing something? AB - Nutrition's impact on the surgical outcome has been established in various surgical specialties. However, data addressing the nutritional aspect following surgery for peritoneal surface malignancies are considered scarce. We aim to evaluate the knowledge, attitudes, and practice of surgeons regarding their nutritional support for patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS and HIPEC) via a survey directed to self-evaluate nutritional knowledge, screening, and practice toward patients. The survey was submitted to the attendees of the International Regional Cancer Therapies Symposium. The response rate was 37% (56/151). Most surgeons estimated their knowledge and malnutrition screening skills in CRS and HIPEC to be 'adequate' or better. Only 35.19% reported the availability of nutritional screening and assessment tools for CRS and HIPEC patients. 86.5% of participants stated that their CRS and HIPEC patients have access to a dietitian on inpatient and outpatient basis. However, only 32.69% reported to 'always' consult a dietitian. Otherwise, the involvement of a nutrition specialist is considered on variable basis. Despite the consensus on the importance of nutrition in HIPEC patients, there appears to be a profound underutilization of nutrition specialists in the patients' management, which may have had in impact on their surgical outcome. PMID- 30298961 TI - Evidence of increased fecal granins in children with irritable bowel syndrome and correlates with symptoms. AB - BACKGROUND: Granins have been implicated in the pathophysiology of irritable bowel syndrome (IBS) in adults. We sought to determine whether fecal granins are altered in children with IBS and associated with symptoms. METHODS: Children (7 12 years of age) with IBS and healthy controls (HC) kept daily pain and stool diaries for 2 weeks. Stool samples were analyzed for chromogranins A and B (CgA, CgB) and secretogranins II and III (SgII, SgIII). Children also completed psychological measures to assess anxiety, depression, somatization, and internalizing symptoms. KEY RESULTS: Fecal CgB and SgIII concentrations were higher in all the boys (IBS plus HC, n = 48) than in all the girls (IBS plus HC, n = 75) (P = 0.02 and P = 0.046, respectively). CgA and SgIII were greater in children with IBS (n = 52) vs HC (n = 69) (P = 0.01, P = 0.017, respectively). CgB and SgII did not differ between groups. In children with IBS, the number of pain episodes per week and mean daily pain rating correlated positively with all four granins. The number of stools per day correlated positively with CgB and SgII, and the percent of diarrheal stools (6 or 7 on the Bristol Scale) correlated inversely with all four granins in boys but not in girls. Fecal granins did not correlate with psychological measures. CONCLUSIONS AND INFERENCES: As measured by fecal granins, there is evidence of neuroimmune activation in children with IBS. Granins are related to abdominal pain symptoms, stooling frequency, and stool form in children with IBS. Sex influences the fecal concentration of CgB and SgIII. PMID- 30298963 TI - Epidermal growth factor receptor promotes glioma progression by regulating xCT and GluN2B-containing N-methyl-d-aspartate-sensitive glutamate receptor signaling. AB - Autocrine and paracrine factors, including glutamate and epidermal growth factor (EGF), are potent inducers of brain tumor cell invasion, a pathological hallmark of malignant gliomas. System xc(-) consists of xCT and CD98hc subunits and functions as a plasma membrane antiporter for the uptake of extracellular cystine in exchange for intracellular glutamate. We previously showed that the EGF receptor (EGFR) interacts with xCT and thereby promotes the activity of system xc(-) in a kinase-independent manner, resulting in enhanced glutamate release in glioma cells. However, the molecular mechanism underlying EGFR-mediated glioma progression in a glutamate-rich microenvironment has remained unclear. Here we show that the GluN2B subunit of the N-methyl-d-aspartate-sensitive glutamate receptor (NMDAR) is a substrate of EGFR in glioma cells. In response to EGF stimulation, EGFR phosphorylated the COOH-terminal domain of GluN2B and thereby enhanced glutamate-NMDAR signaling and consequent cell migration in EGFR overexpressing glioma cells. Treatment with the NMDAR inhibitor MK-801 or the system xc(-) inhibitor sulfasalazine suppressed EGF-elicited glioma cell migration. The administration of sulfasalazine and MK-801 also synergistically suppressed the growth of subcutaneous tumors formed by EGFR-overexpressing glioma cells. Furthermore, shRNA-mediated knockdown of xCT and GluN2B cooperatively prolonged the survival of mice injected intracerebrally with such glioma cells. Our findings thus establish a central role for EGFR in the signaling crosstalk between xCT and GluN2B-containing NMDAR in glioma cells. PMID- 30298964 TI - Transcutaneous electrical acustimulation synchronized with inspiration improves gastric accommodation impaired by cold stress in healthy subjects. AB - BACKGROUND: The aim of this study was to investigate whether transcutaneous electrical acustimulation (TEA) synchronized with inspiration (STEA), a method known to enhance vagal activity, was more effective than TEA in improving cold stress-induced impairment in gastric accommodation (GA) and dyspeptic symptoms in healthy subjects. METHODS: Each of fifteen healthy subjects was studied in five randomized sessions: control (warm nutrient liquid), cold nutrient liquid (CNL), CNL+sham-TEA, CNL+TEA, and CNL+STEA. The subjects were requested to drink Ensure until reaching maximum satiety. STEA was performed using the same parameters as TEA but asking the subjects to breathe in when they sensed each stimulation train. The electrogastrogram (EGG) and electrocardiogram (ECG) were recorded to assess gastric slow waves (GSW) and autonomic functions, respectively. KEY RESULTS: GA was reduced with the CNL in comparison with the warm drink but increased with TEA and STEA; STEA was more potent than TEA in improving GA; STEA was more potent in improving GSW than TEA; STEA significantly increased vagal activity and decreased sympathetic activity compared with TEA. CONCLUSIONS AND INFERENCES: TEA synchronized with inspiration is more potent than TEA in improving cold stress-induced impairment in GA and GSW and dyspeptic symptoms and might be a novel noninvasive therapy for treating stress-induced dysmotility and dyspeptic symptoms. PMID- 30298965 TI - Brain corticotropin-releasing factor signaling: Involvement in acute stress induced visceral analgesia in male rats. AB - BACKGROUND: Water avoidance stress (WAS) induces a naloxone-independent visceral analgesia in male rats under non-invasive conditions of monitoring. The objective of the study was to examine the role of brain CRF signaling in acute stress induced visceral analgesia (SIVA). METHODS: Adult male Sprague-Dawley rats were chronically implanted with an intracerebroventricular (ICV) cannula. The visceromotor response (VMR) to graded phasic colorectal distension (CRD: 10, 20, 40, 60 mm Hg, 20 seconds, 4 minutes intervals) was monitored using manometry. The VMR to a first CRD (baseline) was recorded 5 minutes after an ICV saline injection, followed 1 hour later by ICV injection of either CRF (30, 100, or 300 ng and 1, 3, or 5 MUg/rat) or saline and a second CRD, 5 minutes later. Receptor antagonists against CRF1 /CRF2 (astressin-B, 30 MUg/rat), CRF2 (astressin2 -B, 10 MUg/rat), oxytocin (tocinoic acid, 20 MUg/rat), or vehicle were injected ICV 5 minutes before CRF (300 ng/rat, ICV) or 15 minutes before WAS (1 hour). KEY RESULTS: ICV CRF (100 and 300 ng) reduced the VMR to CRD at 60 mm Hg by -36.6% +/ 6.8% and -48.7% +/- 11.7%, respectively, vs baseline (P < 0.001), while other doses had no effect and IP CRF (10 ug/kg) induced visceral hyperalgesia. Astressin-B and tocinoic acid injected ICV induced hyperalgesia and prevented the analgesic effect of ICV CRF (300 ng/rat) and WAS, while astressin2 -B only blocked WAS-induced SIVA. CONCLUSIONS & INFERENCES: These data support a role for brain CRF signaling via CRF2 in SIVA in a model of WAS and CRD likely mediated by the activation of brain oxytocin pathway. PMID- 30298966 TI - Granulosa cells of prepubertal cattle respond to gonadotropin signaling and upregulate genes that promote follicular growth and prevent cell apoptosis. AB - Oocytes collected from prepubertal animals are known to be less developmentally competent than those from adult animals. There is evidence suggesting that acquisition of developmental competence in bovine oocytes may be linked to the expression profile of genes in the granulosa cells (GCs). Cumulus-oocyte complexes (COC) and GCs were collected from 12 Holstein heifers between 2 and 6 months of age (nine follicle-stimulating hormone [FSH] treated and three untreated) and eight FSH-treated cows. The COCs from prepubertal animals were matured, fertilized, and cultured in vitro to assess development to the blastocyst stage. The relative messenger RNA (mRNA) abundance of FSHR, StAR, CYP19A1, HSD3B1, CX43, FOXO1, and XIAP in GCs were quantified by real-time quantitative polymerase chain reaction. Results from this study revealed that GCs of prepubertal animals respond to FSH treatment by increasing mRNA levels of genes promoting estradiol synthesis and follicular growth ( FSHR and CYP19A1), and preventing cell apoptosis ( XIAP), and by decreasing mRNA levels of genes promoting progesterone production ( StAR and HSD3B1). This study also revealed that the relative mRNA abundance of FOXO1 in GCs is associated with oocyte competence to support embryo development to the blastocyst stage in prepubertal Holstein heifers. PMID- 30298967 TI - Actions helping expressed or anticipated needs: Patients with advanced cancer and their family caregivers' experiences of specialist palliative home care teams. AB - Patients with advanced cancer and family caregivers in palliative care face physical, psychological, social and existential challenges, much of the time home alone. Specialist palliative home care team services can be instrumental for sense of security in an uncertain situation. The aim of this study was to describe patients' and family caregivers' experiences of specialist palliative home care team actions that are identified by the participants as helping or hindering interventions. Six patients and seven family caregivers were interviewed using the enhanced critical incident technique. Ninety-five critical incidents and wish list items were identified. Providing adequate resources, keeping promises and being reliable, and creating partnerships are actions by specialist palliative care teams that patients and family caregivers experienced as helping in meeting expressed or anticipated needs in patients and family caregivers. Being reliable and including patients and family caregivers in partnerships help to continue with daily life, even though death may be close. Unmet needs resulted in experiences of disrespect or violation of personal space/integrity. PMID- 30298968 TI - Exercise training in heart failure: a long way to go yet.

PMID- 30298970 TI - A retrospective study of the impact of supraglottic airway devices on the appearance of neck masses in children undergoing serial magnetic resonance imaging. AB - BACKGROUND: General anesthesia and sedation are used routinely for magnetic resonance imaging (MRI) studies in children to optimize image quality. Airway devices such as supraglottic airways (SGAs) can alter the appearance of cervical soft tissue regions on an MRI and increase the risk of misdiagnosis. This phenomenon has not been well described in vivo. AIMS: We conducted this retrospective study to determine how often SGAs affected the appearance of neck masses in children who received multiple anesthetics for MRIs with and without an SGA. METHODS: We retrieved data on children 17 years old and younger who had multiple MRIs between January 2005 and January 2015. Inclusion criteria were patients with neck masses who had a SGA for at least one MRI and either a natural airway or endotracheal tube (ETT) for another MRI. We reviewed MRI images and imaging reports to determine if SGAs affected the appearance of neck masses. RESULTS: Twelve of the 921 patients who received anesthesia for neck MRIs during the study period met the inclusion criteria. SGAs affected the appearance of the neck mass in 11 of the 12 patients. CONCLUSIONS: Supraglottic airways can significantly alter the appearance of neck masses in children undergoing MRIs and affect radiologists' ability to assess those masses. Communication with the radiologist prior to the induction of anesthesia is crucial when using supraglottic devices in this patient population. It may be more prudent to use a different airway device and/or anesthetic technique when MRIs of these neck masses are undertaken. PMID- 30298971 TI - Greater insulin response to acute fructose ingestion among Maori and Pacific people compared to European people living in Aotearoa New Zealand. AB - BACKGROUND/OBJECTIVES: Fructose consumption has been linked with insulin resistance, obesity, and diabetes, which are more prevalent in those of Maori or Pacific ethnicity compared to New Zealand European. The aim of this study was to determine whether the acute effects of fructose consumption on serum glucose, insulin, lipids and C-reactive protein, differs according to body mass index (BMI) and/or ethnicity. SUBJECTS/METHODS: Maori (n=25), Pacific (n=26) or New Zealand European (n=25) ethnicity, participants consumed a 64g fructose/16g glucose solution. Changes in lipids, glucose, insulin, and C-reactive protein were analyzed using mixed models for repeated measures. RESULTS: After adjustment for age and sex, those with higher BMI had a higher glucose (p=0.0064) and insulin (p=0.0007) response than those with lower BMI. Those of Maori or Pacific ethnicity had similar glucose (p=0.077) to New Zealand European, but higher insulin responses (p=0.0005), which remained after additional adjustment for BMI (p=0.001). Reported sugar sweetened beverages (SSB) intake was higher among Maori and Pacific than New Zealand European (median 1.0 vs 0.0 SSB/day p=0.002). CONCLUSION: Even after adjustment for BMI, those of Maori and Pacific ethnicity have a significantly higher insulin response to fructose than New Zealand Europeans. Higher habitual SSB intake may be a contributing factor. This article is protected by copyright. All rights reserved. PMID- 30298972 TI - Twenty-Four-Hour Diet recall and Diet records compared with 24-hour urinary excretion to predict an individual's sodium consumption: A Systematic Review. AB - This systematic literature review aimed to investigate whether 24 hour diet recall and diet records are reliable and valid ways to measure usual dietary sodium intake compared with 24 hour urinary assessment. We searched electronic databases Medline, Embase, Cinahl, Lilacs, Google Scholar and the Cochrane Library using pre-defined terms Studies were eligible for inclusion if they assessed adult humans in free-living settings, and if they included dietary assessment and 24 hours urinary collection for assessment of sodium intake in the same participants. Studies that included populations with an active disease state that might interfere with normal sodium metabolism were excluded. Results of 20 studies using 24 hour diet recall recall (including 14 validation studies) and 10 studies using food records (including six validation studies) are included in this review. Correlations between estimates from dietary assessment and urinary excretion ranged from 0.16 to 0.72 for 24 hour diet recall, and 0.11 to 0.49 for food diaries. Bland-Altman analysis in two studies of 24 hour diet recall showed poor agreement with 24 hours urinary sodium excretion. These results show that 24 hour diet recall and diet records inaccurately measure dietary sodium intake in individuals compared with the gold standard 24 hours urinary excretion. Validation studies of dietary assessment methods should include multiple days of assessment and 24 hours urine collection, use relevant food composition databases and Bland-Altman methods of analysis. PMID- 30298973 TI - Implementing the proclamation of stroke and potentially preventable dementias. AB - Brain health plays a central role in well-being and in the management of chronic diseases. Stroke and dementia pose the two greatest threats to brain health, but recent developments suggest the possibility that preventing stroke may also prevent some dementias: (a) A large population study showed a 32% decrease in the incidence of stroke and a concomitant 7% reduction in the incidence of dementia; (b) the treatment of atrial fibrillation resulted not only in stroke reduction, but also a 48% decrease in dementia; (c) the hypothesis-free analyses have shown that the first phase of Alzheimer disease involves vascular dysregulation, opening the door to new therapeutic approaches; (d) cognitive impairment, often treatable and reversible, accompanies heart and kidney failure. These developments, combined with the knowledge that stroke, dementia, and heart disease share the same major treatable risk factors, particularly hypertension, offer an opportunity for their joint prevention. This aspiration is expressed by a Proclamation of the World Stroke Organization on Stroke and Potentially Preventable Dementias and endorsed by the World Heart Federation, the World Hypertension League, Alzheimer Disease International, and 18 other international, regional, and national organizations as a call for action. PMID- 30298974 TI - Treatment adherence in systemic sclerosis: A cross-sectional study. AB - BACKGROUND: Treatment adherence is an important medical and pharmaco-economical phenomenon, influenced by multiple variables. Treatment adherence in systemic sclerosis (SSc) has been poorly studied. OBJECTIVE: The aim of the present study was to assess treatment adherence in SSc patients and to identify factors associated with good and poor adherence. METHODS: We conducted a monocentric, cross-sectional, observational study. Treatment adherence was evaluated by the Compliance Questionnaire of Rheumatology (CQR). The necessity of treatment and concerns about treatment were investigated using the Beliefs about Medicines Questionnaire-Specific (BMQ-S). The Illness Perception Questionnaire-Revised (IPQ R) assessed illness perceptions. Disease-related characteristics were collected retrospectively. RESULTS: A total of 66 patients were enrolled in this study. Of these, 47 (71.2%) had a weighted CQR score of <=80% ("poor adherence") and 19 (28.8%) had a weighted CQR score of >80% ("good adherence"). No significant relationship between demographic, clinical or psychological factors and overall adherence could be found, except with the IPQ subscale "timeline acute/chronic" (p = 0.042). Our patient population estimated the necessity of their medication high (mean necessity score 20.5), with moderate concern beliefs (mean concern score 15.1). Subjective adherence, as self-reported by patients, was high. CONCLUSIONS: This study demonstrated low treatment adherence rates in SSc patients. We could not identify demographic, clinical or psychological factors associated with treatment adherence, except with the IPQ subscale "timeline acute/chronic". This suggests a correlation between poor adherence and the belief that the disease will be chronic without improvement over time. Symptom relief was an important motivating factor for taking medication. The treatment necessity was scored higher than treatment concerns, but the necessity beliefs were not associated with adherence. PMID- 30298975 TI - Electrochemical Reduction of Carbon Dioxide to Value-added Products: The Electrocatalyst and Microbial Electrosynthesis. AB - The electrochemical reduction of carbon dioxide (CO2 ) to value-added products obtains great attention and investigation worldwide in recent years. The commercialization of this green process relies on the progress of relating high performance electrocatalysts and their feasibility with proper reactor design. The microbial electrosynthesis (MES) is an alternative route to reduce CO2 with electroactive bio-film electrode as catalyst. This review presents the research status and development of cathode catalysts, particularly focusing on the active sites and development tendency, for highly efficient electrochemical reduction CO2 from personal viewpoint. Some of our results are also presented to exhibit contributions. MES shows a similar process to the typical electrochemical reduction of CO2 . Their combination is an important trend, and the future research in this field is full of challenges and opportunities. PMID- 30298976 TI - Are prothrombin time and clot waveform analysis useful in detecting a bleeding risk in liver cirrhosis? AB - INTRODUCTION: Prothrombin time is thought to be unreliable in cirrhotic patients to predict the risk of bleeding. We investigated whether prothrombin time ratio was an independent risk factor for bleeding alongside its clot waveform analysis. METHODS: We studied 307 consecutive cirrhotic patients and 115 healthy subjects. A coagulometer was used for detecting both prothrombin time and clot waveform analysis which included velocity (1st derivative) and acceleration (2nd derivative) of clot formation, and area of parabolic segment of the 1st and 2nd derivatives of prothrombin time (entire cycle of the clot formation). RESULTS: Logistic regression shows that prothrombin time ratio was the only variable significantly associated with the history of bleeding. Using a hemorrhagic score, the stepwise model included prothrombin time ratio and the area of parabolic segment of the 1st derivative of Prothrombin Time. Odds ratio was used to create a new score to be challenged against the hemorrhagic score in a ROC analysis. The AUC was 0.72, 95% CI: 0.67-0.77. CONCLUSION: Prothrombin time ratio is associated to an increased bleeding risk. Its role may be further emphasized considering clot waveform analysis. The new score, if aggregated to prothrombin time ratio, could be useful to provide a single parameter immediately ready to assess the bleeding risk in the individual cirrhotic patient. PMID- 30298977 TI - Cardiac pacing in cardioinhibitory syncope in children. AB - INTRODUCTION: Reflex vasovagal-or cardioinhibitory syncope is known to be a major cause of recurrent syncope in children. The mechanism of vasovagal syncope (VVS) is an interaction between a vagally mediated bradycardia or asystole and a more or less manifest vasodilatory component. Although pacing is not advisable as a standard approach in patients with VVS, it remains a treatment option of last resort in exceptionally severe cases, or patients with contraindication or refractoriness to drug therapy and life style changes. To effectively avoid VVS in these patients, the pacemaker has to both prevent bradycardia and to compensate for the vasodilatory component. Therefore, this study aimed to evaluate a simple pacemaker setting (VVI pacing with hysteresis) with the potential to prevent VVS in affected children. METHODS: Clinical data of patients, who were presented to the Department for Pediatric Cardiology, Heart Center Leipzig, in the period of 2001-2017 for cardiac pacemaker implantation for cardioinhibitory syncope or pallid breath-holding spells, were collected retrospectively. RESULTS: Eleven pediatric patients, median age 2.7 (0.8-17) years, were included. Pacemaker settings are depicted. In 10 out of 11 patients, an entire abolishment of syncope could be achieved (P = .002). CONCLUSION: The presented VVI pacing with hysteresis seems to be a promising pacemaker setting in pediatric patients with cardioinhibitory syncope who need a pacemaker. Unnecessary ventricular stimulation is effectively avoided, while cardiac output is preserved during cardioinhibition, by providing a sufficient paced heart rate, compensating for the often present vasodilatory component. PMID- 30298978 TI - Quantification of oleacein and oleuropein aglycone in olive oil using deuterated surrogates by normal-phase ultra high performance liquid chromatography with quadrupole time-of-flight mass spectrometry. AB - An analytical method for the analysis of relevant secoiridoid-based components in olive oil, oleacein and oleuropein aglycone, is described using for the first time deuterated surrogates. 0.2 g of sample was necessary to perform the analysis using liquid-liquid extraction and ultrasound-assisted extraction with a mixture of methanol/water (4:1, v/v). To avoid the formation of by-products, normal-phase ultra high performance liquid chromatography was chosen for the chromatographic separation. The selected mobile phase was a gradient mixture of tetrahydrofurane and hexane, and an ACE Excel 3 CN-ES column as stationary phase. The detection and quantification was performed with a SYNAPT G2-Si mass spectrometer. The calibration curves for oleacein and oleuropein aglycone were linear and quadratic, respectively. The validation was done at three levels of concentration. Relative errors from 0.1 to 10.5% and relative standard deviations lower than 9% were obtained. The method was applied to study different samples of olive oil. PMID- 30298979 TI - Corrigendum for Hudgins et al. (2017) https://doi.org/10.1111/ele.12741. PMID- 30298980 TI - Electrometer offset current due to scattered radiation. AB - Relative dose measurements with small ionization chambers in combination with an electrometer placed in the treatment room ("internal electrometer") show a large dependence on the polarity used. While this was observed previously for percent depth dose curves (PDDs), the effect has not been understood or preventable. To investigate the polarity dependence of internal electrometers used in conjunction with a small-volume ionization chamber, we placed an internal electrometer at a distance of 1 m from the isocenter and exposed it to different amounts of scattered radiation by varying the field size. We identified irradiation of the electrometer to cause a current of approximately -1 pA, regardless of the sign of the biasing voltage. For low-sensitivity detectors, such a current noticeably distorts relative dose measurements. To demonstrate how the current systematically changes PDDs, we collected measurements with nine ionization chambers of different volumes. As the chamber volume decreased, signal ratios at 20 and 10 cm depth (M20/M10) became smaller for positive bias voltage and larger for negative bias voltage. At the size of the iba CC04 (40 mm3) the difference of M20/M10 was around 1% and for the smallest studied chamber, the iba CC003 chamber (3 mm3), around 7% for a 10 * 10 cm2 field. When the electrometer was moved further from the source or shielded, the additional current decreased. Consequently, PDDs at both polarities were brought into alignment at depth even for the 3 mm3 ionization chamber. The apparent polarity effect on PDDs and lateral beam profiles was reduced considerably by shielding the electrometer. Due to normalization the effect on output values was low. When measurements with a low-sensitivity probe are carried out in conjunction with an internal electrometer, we recommend careful monitoring of the particular setup by testing both polarities, and if deemed necessary, we suggest shielding the electrometer.

Nevertheless, they often encounter patients with other indications for which they have only limited experience. In such situations it is helpful to consult colleagues who have specialised in the respective areas. The Internet provides the opportunity to connect with other specialists that can be used for peer consulting. We argue that health professionals should learn to make use of online peer consulting during vocational training. METHODS: We used an open source platform that provided the opportunity to chat and upload documents. We recruited 45 first-year physiotherapy students as participants. The training for online peer consulting was integrated into courses where students were taught basic principles of gait analysis and learned how to document the findings of their examinations. Subsequently, the students evaluated the course and the online collaboration. FINDINGS: Students were highly motivated to use the online platform and perceived the online peer consulting and the atmosphere of collaboration on the platform to be very positive. In addition, students had a significant increase in content knowledge and were more confident in their own knowledge than they were before the online peer consulting. DISCUSSION: It seems appropriate to provide training for giving and gathering online peer feedback. This opportunity, provided at an early stage of training, could help prepare students for continuing co-operative exchange in their professional lives. Health care professionals should learn how to gather information from colleagues and how to provide adequate feedback. PMID- 30298982 TI - Brief teaching sessions change behaviour in A&E. AB - BACKGROUND: The Accident and Emergency Department (A&E) is a busy environment that requires time- and resource-efficient teaching. Managing cervical spine (c spine) trauma is often an unfamiliar skill for new doctors starting work in A&E. This study investigated the efficacy of brief teaching interventions in changing clinician behaviour within A&E. The Accident and Emergency Department is a busy environment that requires time- and resource-efficient teaching METHODS: Data for 482 patients receiving c-spine computed tomography (CT) imaging in two Gloucestershire A&Es before and after multimodal departmental teaching were compared. Time taken to CT, indication for CT scan and presence of bony injury were manually recorded from patient management software. RESULTS: Following the provision of teaching, the proportion of CT scans performed within 1 hour did not significantly change, from 31% before teaching to 37.6% after teaching (p = 0.133); however, the mean number of c-spine CT scans performed per week rose from 14.50 to 23.25 (p = 0.0001), and the mean number of CT scans performed per week within 1 hour rose from 4.50 to 8.75 (p <= 0.001). There was no reduction in the quality of these scans, with the proportion detecting bony injury remaining constant, and there was no increase in the proportion of scans not indicated by National Institute for Health and Care Excellence guidelines. CONCLUSIONS: This study demonstrates that brief, low-resource teaching can be associated with a positive change in clinician behaviour. This intervention was straightforward to implement and is likely to be transferable to other guideline-driven investigations. Limitations include the patient cohort being proportionately older than that found in major trauma centres, and a lack of data on patients in whom CT scans were indicated but not performed.

AB - INTRODUCTION: A cardiac cause is an extremely rare etiology of pediatric chest pain. Despite its low sensitivity/specificity, exercise stress testing (EST) is widely used to determine the prognosis in patients with suspected/established coronary disease. We aimed to look at the utility of a combined cardiopulmonary EST in the evaluation of pediatric patients with chest pain. METHODS: After institutional review board approval, a retrospective chart review was performed of all pediatric patients who were referred for an EST for chest pain from January 2014 to 2017. Patients with incomplete records, severe congenital heart disease, and a prior EST were excluded. RESULTS: A total of 389 patients met the inclusion criteria. Echocardiogram (ECHO) was performed on 333 (85.6%) patients and 43 (11%) previously unknown structural cardiac anomalies were identified. A total of 76 (19.5%) patients had an abnormal EST with the 3 most common causes being related to the respiratory system. Only four patients had both an abnormal exercise stress test and an incidental structural anomaly on ECHO but none of them had their symptoms recreated during the EST. CONCLUSION: Only 1% of patients previously undiagnosed with heart disease had an abnormal stress test and an incidental anomaly on ECHO. These ECHO anomalies were unlikely to be the cause of chest pain. Furthermore, since the majority of abnormal stress tests were secondary to a pulmonary cause, a complete cardiopulmonary EST may be an effective screening tool for certain patients presenting with chest pain. Our study emphasizes the need for performing a complete cardiopulmonary EST instead of an isolated cardiac stress test to maximize diagnostic efficiency and yield.

AB - European Union Directive 2013/39/EU, which amended and updated the Water Framework Directive (WFD; 2000/60/EC) and its daughter directive (2008/105/EC), sets Environmental Quality Standards for biota (EQSbiota ) for a number of bioaccumulative chemicals. These chemicals pose a threat to both aquatic wildlife and human health via the consumption of contaminated prey or the intake of contaminated food originating from the aquatic environment. EU member states will need to establish programs to monitor the concentration of 11 priority substances in biota and assess compliance against these new standards for the classification of surface water bodies. An EU-wide guidance effectively addresses the implementation of EQSbiota . Flexibility is allowed in the choice of target species used for monitoring to account for both diversity of habitats and aquatic community composition across Europe. According to that guidance, the consistency and comparability of monitoring data across member states should be enhanced by adjusting the data on biota contaminant concentrations to a standard trophic level by use of the appropriate trophic magnification factor (TMF), a metric of contaminant biomagnification through the food web. In this context, the selection of a TMF value for a given substance is a critical issue, because this field derived measure of trophic magnification can show variability related to the characteristics of ecosystems, the biology and ecology of organisms, the experimental design, and the statistical methods used for TMF calculation. This paper provides general practical advice and guidance for the selection or determination of TMFs for reliable application within the context of the WFD (i.e., adjustment of monitoring data and EQS derivation). Based on a series of quality attributes for TMFs, a decision tree is presented to help end users select a reasonable and relevant TMF. Integr Environ Assess Manag 2018;00:00-00. (c) 2018 The Authors.

AB - From the viewpoint of element strategy, non-Li batteries with promising negative and positive electrodes have been widely studied to support a sustainable society. To develop non-Li batteries having high energy density, research on electrolyte materials is pivotal. Solvate ionic liquids (SILs) are an emerging class of electrolytes possessing somewhat superior properties for battery applications compared to conventional ionic liquid electrolytes. In this account, we describe our recent efforts regarding SIL-based electrolytes for Li, Na, K, and Mg batteries with respect to structural, physicochemical, and electrochemical characteristics. Systematic studies based on crystallography and Raman spectroscopy combined with thermal/electrochemical stability analysis showed that the balance of competitive cation-anion and cation-solvent interactions predominates the stability of the solvate cations. We also demonstrated battery applications of SILs as electrolytes for non-Li batteries, particularly for Na batteries.

AB - BACKGROUND: In this study, we compared our experience about early and midterm follow-up outcomes for right anterolateral minithoracotomy (RAMT) vs full sternotomy (FS) in surgical aortic valve replacement (AVR) among adolescents with bicuspid aortic valve (BAV). METHODS: Patients were retrospectively enrolled from January 2008 to December 2017. Inclusion criteria were patients with BAV who had to undergo to AVR. They were divided in two groups: RAMT and FS. The choice of RAMT was based on individual surgeon's preferences or when expressly requested by patient that was informed of nonconventional approach. RESULTS: We enrolled 61 patients, 23 in RAMT group and 38 in FS group. The mean age was 15.6 +/- 1.7 years for RAMT group and 16.1 +/- 1.5 years for FS group (P = .23). The RAMT group had a higher prevalence of female gender (P = .04). The patients in the RAMT group had longer cardiopulmonary bypass (115.2 +/- 18.5 vs 102.2 +/- 16.5 min; P = .006) and cross-clamp time (78.6 +/- 18.1 vs 74.3 +/- 15.2 min; P = .01). No patients required intraoperative conversion to FS. No differences were found in ventilation times, postoperative intensive care unit (ICU), and hospital length of stay for both groups. Follow-up echocardiograms were available for all patients at median of 5.2 years (range 0.5-9.6 years, median 5.4 years for RAMT and 5.1 for FS) and no patient required reoperation for aortic prosthesis malfunction. CONCLUSIONS: Our study shows that RAMT is safe and effective as FS. Although the RAMT operation takes slightly more operation time, it is not associated with major adverse effects.

AB - As a persistent organic pollutant, perfluorooctane sulfonate has drawn a worldwide attention. In this contribution, a novel molecularly imprinted polymer based on mesoporous silica nanoparticles was prepared for efficient separation and enrichment of perfluorooctane sulfonate in water samples. The polymer was characterized by transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, and N2 adsorption/desorption experiments. The static adsorption experiments and the adsorption kinetic tests were conducted. The results showed that the adsorbents had high adsorption capacity (21.10 mg/g) and short adsorption equilibration time (25 min). Meanwhile, the effect of mesoporous silica nanoparticles on the adsorption capacity was investigated. The results indicated that the mesoporous structure helped to increase the adsorption capacity of adsorbent to adsorbate. Besides, the adsorbents show good specificity and good reusability with the adsorption capacity of adsorbent toward perfluorooctane sulfonate decreasing <5% after five adsorption-desorption cycles. The mesoporous silica nanoparticles molecularly imprinted polymer has been used successfully for the removal of perfluorooctane sulfonate in environmental water samples with relative standard deviation <=4.64%. PMID- 30298989 TI - Analysis of insulin and insulin analogs from dried blood spots by means of liquid chromatography-high resolution mass spectrometry. AB - While dried blood spot (DBS) analysis concerning low molecular mass molecules has become more and more established in various fields of analytical chemistry, the utility of DBS in determining peptides and proteins from DBS is yet comparably limited. In consideration of the fact that the apparent benefits of DBS sampling are similar for analytes of lower and higher molecular mass, dedicated (non generic) sample preparation procedures are required that meet the needs for detecting peptidic drugs and hormones in DBS. The analysis of insulin and its synthetic analogs by mass spectrometry has received increased attention in several fields such as doping controls, forensics, and drug metabolism and pharmacokinetics studies. Hence, a strategy facilitating the analysis of insulin and its synthetic or animal analogs (human, Lispro, Aspart, Glulisine, Glargine, Detemir, Tresiba, and porcine and bovine insulin) from DBS was developed. The successful analysis of these substances at physiologically relevant concentrations was realized after ultrasonication-assisted extraction, immunoaffinity purification, and liquid chromatographic separation followed by high resolution mass spectrometric detection (with or without ion mobility). Assay validation demonstrated adequate sensitivity (LOD 0.5 ng/mL for most insulins), as well as precise (< 25%) and reproducible results for all included target insulins. Additionally, proof-of-principle data were obtained by the analysis of DBS samples obtained from healthy volunteers in non-fasting state as well as a sample from a diabetic volunteer treated with the fast acting analog insulin Aspart. PMID- 30298990 TI - Factors associated with patients' willingness to consider joint surgery after completion of a digital osteoarthritis treatment program: A prospective cohort study. AB - OBJECTIVES: To examine patient willingness and possible shift in willingness for surgery and to investigate factors associated with this shift, following participation in the digital non-surgical osteoarthritis (OA) treatment program Joint Academy. METHODS: 458 individuals (mean age 62+/-5.6 years, 67% women) with diagnosed hip or knee were evaluated after six weeks in Joint Academy, comprising education and exercise as well as asynchronous chat with a physical therapist. Data describing joint pain, health-related quality of life (EQ-5D-3L), walking difficulties, 30-second Chair Stand Test (30CST) and willingness to consider surgery were collected at baseline and at six weeks. RESULTS: At follow-up, 31% of those willing to consider surgery at baseline no longer considered surgery. Of those who were unwilling to consider surgery at baseline, 6% re-considered and considered surgery at follow-up. Less pain and a higher EQ-5D-3L index at six weeks were associated with the shift from being willing to unwilling to consider surgery at follow-up (OR=0.67-1.64, p<0.05). Worse pain, a lower EQ-5D-3L index and having walking difficulties at six weeks, and a lower pain and EQ-5D-3L index improvement were associated with the shift from being unwilling to willing to consider surgery at six weeks (OR=0.51-4.30, p<0.005). CONCLUSIONS: Evidence based non-surgical OA treatment, at least delivered digitally, may reduce the need for surgery and should therefore be offered as the first-line treatment option to patients with hip and knee OA. Result also supports the notion that such treatment programs have the potential to improve selection of patients for total joint replacement. This article is protected by copyright.

AB - Single chain variable fragment-IgGs (scFv-IgG) are a class of bispecific antibodies consisting of two single chain variable fragments (scFv) that are fused to an intact IgG molecule. A common trend observed for expression of scFv IgGs in mammalian cell culture is a higher level of aggregates (10%-30%) compared to mAbs, which results in lower purification yields in order to meet product quality targets. Furthermore, the high aggregate levels also pose robustness risks to a conventional mAb three column platform purification process which uses only the polishing steps (e.g., cation exchange chromatography [CEX]) for aggregate removal. Protein A chromatography with pH gradient elution, high performance tangential flow filtration (HP-TFF) and calcium phosphate precipitation were evaluated at the bench scale as means of introducing orthogonal aggregate removal capabilities into other aspects of the purification process. The two most promising process variants, namely Protein A pH gradient elution followed by calcium phosphate precipitation were evaluated at pilot scale, demonstrating comparable performance. Implementing Protein A chromatography with gradient elution and/or calcium phosphate precipitation removed a sufficient portion of the aggregate burden prior to the CEX polishing step, enabling CEX to be operated robustly under conditions favoring higher monomer yield. From starting aggregate levels ranging from 15% to 23% in the condition media, levels were reduced to between 2% and 3% at the end of the CEX step. The overall yield for the optimal process was 71%. Results of this work suggest an improved three-column mAb platform-like purification process for purification of high aggregate scFv-IgG bispecific antibodies is feasible.

CNZ-1 is capable of producing Au NPs under various conditions. Results showed that initial concentration of Au[III], pH values and electron donors affected nucleation of Au NPs by CNZ-1, resulting in different apparent color of the as-obtained bio-Au NPs, which were further characterized by UV-Vis, TEM, XRD and XPS analyses. Mechanism studies revealed that Au[III] was first reduced to Au[I] and eventually reduced to EPS-coated Au0 NPs. FTIR and FEEM analyses revealed that some amides and humic acid-like matters were involved in the production of bio-Au NPs through CNZ-1 cells. In addition, we also found that the catalytic activity of bio-Au NPs for 4-nitrophenol (4-NP) reduction could be enhanced by various metal ions (Ca2+ , Cu2+ , Co2+ , Fe2+ , Fe3+ , Ni2+ , Sr2+ and Cr3+ ) and metal oxides (Fe3 O4 , Al2 O3 and SiO2 ), which is beneficial for their further practical application. The maximum zero-order rate constant k1 and first-order rate constant k2 of all metal ions/oxides supplemented systems can reach 99.65 mg/(L. min) and 2.419 min-1 , which are 11.3 and 12.6-fold higher than that of control systems, respectively.

AB - Recombinant adeno-associated viral vectors (rAAV) are promising therapies for genetic diseases. Although current platforms for recombinant vector production can generate drug material for pre-clinical and clinical studies, rAAV biomanufacturing will eventually face commercial supply challenges if per cell vector productivity and process scalability are not improved. Because considerable efforts have traditionally focused on optimizing rAAV plasmid design, herein we investigate the impact of host cell proteins on vector production to identify proteins that may enhance rAAV yield. Using a rAAV2-GFP producing Saccharomyces cerevisiae model in combination with the yeast Tet Hughes Collection screening library, we identified 22 gene candidates that improved rAAV DNA replication (rAAV-GFP/18s rDNA ratio) and vector yield (benzonase-resistant rAAV DNA vector genome titer) as high as 6-fold and 15-fold relative to control, respectively. The candidate proteins participate in biological processes such as DNA replication, ribosome biogenesis, and RNA and protein processing. The best five candidates (PRE4, HEM4, TOP2, GPN3, and SDO1) were further screened by generating overexpression mutants in the YPH500 yeast strain. Subsequent clone evaluation was performed to confirm the rAAV-promoting activity of selected candidates under plate-based and bioreactor-controlled fermentation conditions. Digital droplet PCR analysis of cell lysate and AVB resin-purified material confirmed HEM4 and TOP2 overexpression mutants displayed the highest per cell total rAAV DNA productivity (1.6 and 1.7-fold increase over control, respectively) and per cell vector productivity (3 and 4-fold over control, respectively). This evaluation confirmed that overexpression of HEM4 and TOP2 proteins enhanced total and benzonase-resistant rAAV DNA yield. Further studies are needed to understand their mechanism of action and to assess their potential application in molecular strategies for rAAV production.

AB - Biopharmaceutical protein manufacturing requires the highest producing cell lines to satisfy current multiple grams per liter requirements. Screening more clones increases the probability of identifying the high producers within the pool of available transfectant candidate cell lines. For the predominant industry mammalian host cell line, Chinese hamster ovary (CHO), traditional static-batch culture screening does not correlate with the suspension fed-batch culture used in manufacturing, and thus has little predictive utility. Small scale fed-batch screens in suspension culture correlate better with bioreactor processes but a limited number of clones can be screened manually. Scaled-down systems, such as shaken deep well plates, combined with automated liquid handling, offer a way for a limited number of scientists to screen many clones. A statistical analysis determined that 384 is the optimal number of clones to screen, with a 99% probability that six clones in the 95th percentile for productivity are included in the screen. To screen 384 clones efficiently by the predictive method of suspension fed-batch, the authors developed a shaken deep-well plate culturing platform, with an automated liquid handling system integrating cell counting and protein titering instruments. Critical factors allowing deep-well suspension culture to correlate with shake flask culture were agitation speed and culture volume. Using our automated system, one scientist can screen five times more clones than by manual fed-batch shake-flask or shaken culture tube screens and can identify cell lines for some therapeutic protein projects with production levels greater than 6 g/L.

AB - In order to address the increasing demand for biologics, cell culture intensification using perfusion offers significantly higher productivities while also reducing manufacturing costs, especially when part of an integrated, continuous bioprocess. An initial study of a long-duration perfusion process using a cell-bleed to maintain a target cell density observed a 2.1-fold higher cell-specific productivity and a gradual decline in the culture growth rate when perfused at an overall lower rate. Subsequent studies sought an alternative process that largely reduced the overall volume of media needed by first perfusing at a high cell-specific perfusion rate (CSPR) to support a high cell density followed by continued perfusion at a low CSPR to promote a more productive stationary phase. This high intensity, low-volume perfusion (HILVOP) process achieved cumulative volumetric productivities of 1.5-1.6 g/L/day with two CHO cell lines. When compared to each cell line's respective commercial-ready, fed-batch process, a 3.1-3.8-fold productivity increase was demonstrated while yielding similar product quality. Furthermore, the higher productivity achieved with HILVOP used 6.6-12.3-fold less media than a similarly productive long duration process.

AB - Osteopontin (OPN) is a structural protein with potential value in therapeutic and diagnostic applications. Low titer, acidic isoelectric point, and the lack of well-defined secondary and tertiary structure were some of the challenges that complicated purification development of OPN from recombinant Escherichia coli lysates. Reported processes for OPN recovery from recombinant sources use nonorthogonal unit operations and often suffer from low yield. In this work, we expanded the search for an optimal OPN purification method by including mixed modal resins with both ionic and hydrophobic properties (Capto adhere, HEA HyperCel, and PPA HyperCel). Plate-based high-throughput screening (HTS) platform revealed useful information about the interactions between the three different ligands and OPN as function of pH and ionic strength. The HTS data allowed the selection of OPN adsorption and elution conditions that were tested and optimized in a batch mode. In terms of purification factor and yield, HEA HyperCel performed significantly better than the other two mixed-modal resins. Pairing HEA HyperCel with a strong anion exchange step (Capto Q) resulted in a two-step purification process that achieved 45-fold purification of OPN with a final purity of 95% and 44% overall yield. The orthogonality provided by mixed-modal and ion exchange steps resulted in higher yield in fewer unit operations than reported processes.

AB - OBJECTIVES: Total saponins from the leaves of Panax notoginseng saponins (SLPN) could inhibit development of depression, but the underlying mechanisms remains unclear. This study aimed to address the roles of circular RNAs in depression inhibition by SLPN. METHODS: The mouse chronic unpredictable mild stress (CUMS) model was established, which were confirmed by mouse weight, forced swimming test (FST) and tail suspension test (TST). Effects of SLPN on depression were evaluated in CUMS through these same assays. Circular RNA profiles in mouse ventral medial prefrontal cortex (VMPC) and hippocampus of CUMS mice were determined by high-through sequencing, followed by confirmation via qRT-PCR. Overexpression of mmu_circ_0001223 was done by transfection of PC12 cell through lentiviral system. Protein abundances of cAMP response element binding protein 1(CREB1) and brain-derived neurotrophic factor (BDNF) were evaluated by western blotting. RESULTS: Mouse body weight, immobility time in FST and immobility time in TST of CUMS mice were significantly recovered by SLPN treatment. A large number of circular RNAs were differentially expressed in the ventral medial prefrontal cortex (VMPC) and hippocampus tissues of CUMS mice. Among them, mmu_circ_0001223 expression was greatly decreased in CUMS mice, but significantly elevated by SLPN treatment. The protein levels of CREB1 and BDNF were also remarkably promoted in CUMS mice by treatment of SLPN. Overexpression of mmu_circ_0001223 enhanced CREB1 and BDNF protein levels in PC12 cells. CONCLUSION: SLPN regulate the expression of large number circular RNAs in CUMS mice, which might be important mediators of SLPN's anti-depression effects.

AB - Microalgal biomass was hydrolyzed using a solid acid catalyst with the aid of liquid acid. The use of solid acid as the main catalyst instead of liquid acid was to omit subsequent neutralization and/or desalination steps, which are commonly required in using the resulting hydrolysates for microbial fermentation. The hydrolysis of 10 g/L of lipid-extracted Chlorella vulgaris containing 12.2% carbohydrates using 7.6 g/L Amberlyst 36 and 0.0075 N nitric acid at 150 degrees C resulted in 1.08 g/L of mono-sugars with a yield of 88.5%. For hydrolysis of higher concentrations of the biomass over 10 g/L, the amount of Amberlyst 36 needed to be increased in proportion to the biomass concentration to maintain similar levels of hydrolysis performance. Increasing the solid acid concentration protected the surface of the solid acid from being severely covered by cell debris during the reaction. A hydrolysate of lipid-extracted C. vulgaris 50 g/L was used, with no post-treatment of desalination, for the cultivation of Klebsiella oxytoca producing 2,3-butanediol. Cell growth in the hydrolysate was found to be almost the same as in the conventional medium with the same monosaccharide composition, confirming its fermentation compatibility. It was noticeable that the yield of 2,3-butanediol with the hydrolysate was observed to be 2.6 times higher than that with the conventional medium.

AB - BACKGROUND: Skateboarders, snowboarders, and surfers all show stance preferences for which foot is forward while moving. We are unaware of other animals than humans with a stance preference, perhaps excepting Osprey, who fly their caught fish beneath them in a foot-forward stance. We hypothesize there should be no difference between left foot forward, right foot back (conventional) versus right foot forward left foot back (goofy) stances or for fish holding with unilateral left or right foot. Online, publicly available, convenience images of Osprey catching fish were accessed and assessed by five independent reviewers using different Internet search engines or online photo series. Stance preference and footedness were tested using chi-square analysis. RESULTS: Stance preferences were evident with the left foot forward (conventional stance) on average 64-78% of the time (all p < 0.02). No difference in foot preference for either one-foot grabs of fish during flight or for non-flight nest/perch fish holding was evident. CONCLUSION: Flight stance of Osprey holding fish shows a lateralized preference in a proportion similar to skateboarders of surfers. We discuss stance preferences in the setting of complex movements and potential flight and survival advantages for Osprey.

AB - The synthesis of nonnatural phospholipid, phosphatidylhydroxybutyrate (PB), was firstly introduced by phospholipase D (PLD)-mediated transphosphatidylation of phosphatidylcholine (PC) with sodium gamma-hydroxybutyrate (NaGHB) in the aqueous solid system. Nanoscale silicon dioxide (NSD) was employed as a carrier to provide an "artificial interphase" between PC and PLD. Special attention has been paid to the effect of the PC coverage on the surface area of hybrids of NSD-PC, the PC loading and the yield of PB. Results indicated that the highest PC loading of 98.3% and the highest PB yield of 97.3% were achieved. In addition, the free PLD in the aqueous-solid system showed the greater stability and pH tolerance than that in the traditional liquid-liquid system. The operational stability of free PLD solution was investigated. The yield of PB remained 70.7% after being used for five batches. The authors provide a new idea for drug design and the potential source of PB for medical experiments. PB is a potential drug and may have the excellent performance in the treatment of central nervous system's diseases. (c) 2018 American Institute of Chemical Engineers Biotechnol. Prog., 2018.

AB - Aqueous micellar two-phase system (AMTPS) is an extractive technique of biomolecule, where it is based on the differential partitioning behavior of biomolecule between a micelle-rich and a micelle-poor phase. In this study, an AMTPS composed of a nonionic surfactant, Triton X-100 (TX-100) was used for purifying a bacteriocin-like inhibitory substance (BLIS) derived from Pediococcus acidilactici Kp10. The influences of the surfactant concentration and the effect of additives on the partitioning behavior and activity yield of the BLIS were investigated. The obtained coexistence curves showed that the mixtures of solutions composed of different surfactant concentrations (5-30% w/w) and 50% w/w crude load were able to separate into two phases at temperatures of above 60 degrees C. The optimum conditions for BLIS partitioning using the TX-100-based AMTPS were: TX-100 concentration of 22.5% w/w, CFCS load of 50% w/w, incubation time of 30 min at 75 degrees C, and back-extraction using acetone precipitation. This optimal partitioning resulted in an activity yield of 64.3% and a purification factor of 5.8. Moreover, the addition of several additives, such as sorbitol, KCl, dioctyl sulfosuccinate sodium salt, and Coomassie(r) Brilliant Blue, demonstrated no improvement in the BLIS separation, except for Amberlite(r) resin XAD-4, where the activity yield was improved to 70.3% but the purification factor was reduced to 2.3. Results from this study have demonstrated the potential and applicability of TX-100-based AMTPS as a primary recovery method for the BLIS from a complex fermentation broth of P. acidilactici Kp10.

AB - Large-scale transient expression in mammalian cells is a rapid protein production technology often used to shorten overall timelines for biotherapeutics drug discovery. In this study we demonstrate transient expression in a Chinese hamster ovary (CHO) host (ExpiCHO-STM) cell line capable of achieving high recombinant antibody expression titers, comparable to levels obtained using human embryonic kidney (HEK) 293 cells. For some antibodies, ExpiCHO-STM cells generated protein materials with better titers and improved protein quality characteristics (i.e., less aggregation) than those from HEK293. Green fluorescent protein imaging data indicated that ExpiCHO-STM displayed a delayed but prolonged transient protein expression process compared to HEK293. When therapeutic glycoproteins containing non-Fc N-linked glycans were expressed in transient ExpiCHO-STM, the glycan pattern was unexpectedly found to have few sialylated N-glycans, in contrast to glycans produced within a stable CHO expression system. To improve N-glycan sialylation in transient ExpiCHO-STM, we co-transfected galactosyltransferase and sialyltransferase genes along with the target genes, as well as supplemented the culture medium with glycan precursors. The authors have demonstrated that co transfection of glycosyltransferases combined with medium addition of galactose and uridine led to increased sialylation content of N-glycans during transient ExpiCHO-STM expression. These results have provided a scientific basis for developing a future transient CHO system with N-glycan compositions that are similar to those profiles obtained from stable CHO protein production systems.

AB - In September 2016, a team of nurses from East and North Hertfordshire NHS Trust (ENHT) and the University of Hertfordshire in England travelled to Kerala, India to interview and recruit nurses for the trust's acute hospital. Before undertaking the interviews, the team visited a nursing college and two hospitals. Based on the findings from these visits and from meeting the interview candidates, the team designed a bespoke mentoring programme for Keralan nurses recruited to ENHT to ease the transition into nursing and living in the UK. This article explores the challenges associated with recruiting and retaining nurses from overseas, and discusses how these can be addressed to ensure that these nurses practise safely and are supported effectively.

PMID- 30299021 TI - Clinical use of Basophil Activation Test (BAT) in drug, food and hymenoptera venom allergies. AB - The basophil activation is emerging as a reliable and robust in vitro biomarker of in vivo allergy reactions. Basophil Activation Test (BAT), intended as in vitro stimulation of patient blood basophil with allergens, followed by flow cytometric detection and quantification of such activation, is nowadays a well established assay in a growing number of routine diagnostic labs. The advancements in the standardization of BAT testing and first convincing clinical evidence are behind this spreading of the assay in clinical lab. BAT is essentially an assay with superior specificity compared to any other allergy testing and, if appropriately used, it can have a valuable clinical utility in different field of allergy diagnosis. In drug allergy, very few testing opportunity are available for the numbers of drugs actually in the market. Antibiotics and analgesics are just two of the categories of drugs were BAT testing can have an added value for the limited specificity of IgE testing or limited availability of other lab testing. In food allergy, BAT is emerging as the more accurate assay to predict an in vivo reaction to food, helping in the discrimination of patients that are only sensitized versus the patient really allergic to an allergen. Furthermore BAT testing determining the basophil sensitivity can be useful for monitoring the natural resolution of allergies and clinical responses to immunomodulatory treatment for food allergies. For this characteristic, BAT has the potential to reduce the need of Oral Food Challenge (OFC). In the hymenoptera venom allergy, BAT is an effective tool in identifying primary sensitizing antigen and in the follow up of patient in venom immunotherapy. With this review, we want to present current state of BAT testing focusing on the clinical laboratory parameters and issue of this assay. A highlight on the standardization needs of BAT is provided, together with considerations on further developments and clinical evidences still to be achieved.

AB - Objective: To conduct a comparative analysis of the emotional and personality characteristics of patients with irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) in remission with IBS-like symptoms. Patients and methods: This study carried out based at a specialized gastroenterology clinic in the period from 2010 to 2015 included 125 patients with IBS (IBS-D - 46, IBS-C - 20, IBS-M - 59) and 37 patients with IBD in remission: Crohn's disease (CD) - 11 and ulcerative colitis (UC) -26 patients. The levels of depression (Beck questionnaire), urgent and personal anxiety (Spielberger questionnaire), the degree of alexithymia (Toronto scale) as well as the severity of psychopathology and behavioral symptoms (PBS) were estimated. Results: Patients with IBS were not significantly different from those with IBD in remission with IBS-like symptoms in terms of depression, actual anxiety, alexithymia and PBS. Only the index of personal anxiety was significantly higher in the group of patients with IBS compared with IBD in remission with IBS-like symptoms (p = 0.0376). Men with IBS exhibited significantly higher actual anxiety than men with IBD (p = 0.04). Maximum severity of depression, anxiety and alexithymia was documented in the locking version of IBS (IBS-C) in comparison with other variants of IBS (p <0.05). Patients with CD in remission are characterized by higher rates of depression and alexithymia compared to UC (p <0.05). Behavioural disorders are most pronounced in the diarrheal variant of IBS and CD. Conclusion: A higher personal anxiety was observed in patients with IBS compared to those in remission of IBD with IBS-like symptoms although other parameters were not significantly different. Patients with IBS-C were characterized by more pronounced manifestations of emotional and personality disorders. More severe emotional and behavioral disorders distinguish CD from UC. PMID- 30299022 TI - Meeting nutritional needs of infants under 3 months of life within the first week after cardiovascular surgery. AB - BACKGROUND: After heart surgery requiring cardiopulmonary bypass, neonates have a profound metabolic response to stress. If adequate nutritional support is not provided this leads to loss of lean mass and deterioration of vital organs. Our objective was to describe the nutritional status and nutritional support achieved in infants younger than 3 months of life undergo in cardiovascular surgery. METHODS: A prospective, descriptive study was conducted in a Pediatric Cardiovascular intensive therapy at tertiary care center. All patients younger than 3 months of life admitted to the cardiovascular unit undergoing heart surgery between April 2013 and May2014 were included. We proposed to achieve 67 kcal/kg/day as one of the nutritional intervention goals. The children were evaluated on admission and at 3 and 7 days post-surgery. RESULTS: 74 patients were evaluated. Total parenteral nutrition could be implemented in all patients that were entered into the protocol requiring parenteral nutrition. Mean volume administered over this period was 50 ml/kg/day (range, 25 to 80ml/kg/day). Evaluation on admission, at 72 hours, and one week postoperatively showed that 70%, 69%, and 62.7%of the patients, respectively, were not able to achieve the 67 kcal/kg/day proposed as one of the nutritional intervention goals. It was found that at the three study time points enteral and parental caloric intake could cover 100% of the metabolic resting energy expenditure (REE) estimated using the Schofield and WHO equations with no significant differences between both. CONCLUSIONS: Although the calorie intake proposed by our intervention was not achieved, it did cover 100% of the REE calculated by the equations.

AB - BACKGROUND: Dance Therapy can improve the quality of life for a person with several conditions, especially psychological wellbeing and quality of life, in the short and longterm. The aim of the study was to examine the effects of the Dance Therapy (DT) on specific learning disability (SLD) children. We wanted to test the impact on cognitive and emotional patterns on children with learning disorders. METHODS: A two arm cluster randomized control study was applied comparing 2 groups of SLD children (treated vs non treated). All children have been measured applying psychological battery before and at the end of the experimental protocol. RESULTS: Our data revealed significant differences between groups for auditory and visual recognition, for interpersonal relationships and for emotions recognition. DT seemed to provide positive evidence as an educational intervention for children with SLDs. CONCLUSIONS: Our results confirmed that DT protocol was an effective way to improve selfesteem, attention and concentration and emotional recognition in SLD children. PMID- 30299025 TI - Increased parental perception of sleep disordered breathing in a cohort of infants with ALTE/BRUE events. AB - BACKGROUND: An apparent life-threatening event (ALTE) describes an acute, unexpected change in an infant's breathing, aspect, or behavior frightening to the parent or caretaker. According to the new recent terminology, clinicians should use the term Brief Resolved Unexplained Event (BRUE) to describe an event occurring in an infant <1 year of age when the observer reports a sudden, brief, and now resolved episode. The aims of the present study in infants were: to investigate sleep disturbances in both ALTE event and after their classification according the new BRUE criteria. METHODS: We enrolled (from April to May 2016) 32 consecutive infants referred to our ambulatory for sleep disorders for follow-up after an ALTE episode and 32 pair healthy controls. We administered to parents the adapted questionnaire "Sleep Disturbance Scale for Children - SDSC". RESULTS: Among enrolled infants with ALTE, there were 26 infants in line with the new BRUE definition, of which 10 at low risk and 16 at the high-risk event. CONCLUSIONS: BRUE had more referred-by-parents' sleep symptoms than controls. In particular, sleep disordered breathing wa prevalent in both, requiring a longer follow-up for this disturbance. PMID- 30299026 TI - The numerical value of fluid balance to predict survival in neonates requiring extracorporeal membrane oxygenation. AB - BACKGROUND: To understand numerical variation of fluid balance in neonates requiring Extracorporeal membrane oxygenation (ECMO) and to assess the relationship between hourly fluid balance and mortality. METHODS: This is a prospective cohort study. All neonates supported by ECMO were enrolled from October 2011 to September 2017. All of the enrolled neonates were divided into survival group and non- survival group. The numerical value of fluid balance of the enrolled neonates were recorded at 6h, 12h, 24h, 36h and 48h after initiation of ECMO respectively. The differences between the two groups were compared. The numerical value of fluid balance predict survival by the receiver operating characteristic (ROC) curve. RESULTS: Forty- eight neonates were enrolled, in which 35 cases were survival and the survival rate was 72.9%. The numerical value of fluid balance in the survival group were lower than that in the non-survival group at 6h, 12h, 24h, 36h and 48h after ECMO(all P < 0.05). The area under ROC curve at 6h, 12h, 24h, 36h and 48h after initiation of ECMO was 0.835, 0.900, 0.839, 0.909 and 0.974 respectively. There were statistically significant in the numerical value of fluid balance predicting survival (all P < 0.05) and a high sensitivity, specificity and positive predictive value at the each time point. CONCLUSIONS: The negative hourly fluid balance were associated with decreased mortality, and the lower the numerical value of fluid balance in neonates requiring ECMO, the higher the survival rate. PMID- 30299027 TI - A study on the effect of joint detection of biochemical markers and electrophysiological examination in the early diagnosis of children with Green Barre syndrome. AB - BACKGROUND: To investigate the effect of early diagnosis in children with GreenBarre syndrome (GBS) via joint detection of biochemical markers and electrophysiological examination. METHODS: A total of 90 children with (GBS collected from the Department of Neurology, intensive care unit (ICU), Rehabilitation Department of Cerebral Palsy of Children's Hospital Affiliated to Zhengzhou University, Department of Pediatrics of First Affiliated Hospital of Zhengzhou University and Henan Province People's Hospital were selected as the research objects. According to their onset time, they were divided into group A (n=30) hospitalized within 3 days of onset, group B (n=30) hospitalized from 4 to 7 days of onset, and group C (n=30) hospitalized after more than 7 days of onset. The titer levels of serum antiganglioside immunoglobulin G (IgG) antibodies, the motor nerve conduction velocity (MCV), Hoffmann reflex (Hreflex) condition and serum immunoglobulin in all groups of children were compared. RESULTS: The levels of serum antiganglioside IgG antibodies in three groups of children from low to high were group A < group B < group C. MCV decreasing rates in group A, B and C were successively 3.33%, 16.66% and 29.99%, namely group A < group B < group C. 60 cases of H reflex were detected in each group, and the abnormal rates were successively 76.66%, 81.66% and 95% respectively in group A, group B and group C, namely group A < group B < group C. The serum levels of immunoglobulin in three groups of children from low to high were group A < group B < group C (p<0.05). CONCLUSIONS: Anti-ganglioside antibody, electrophysiological parameter and serum level of immunoglobulin can be helpful in the diagnosis of GBS, and the changes in them can be monitored clinically so as to carry out the early treatment effectively for children and improve the prognosis. PMID- 30299028 TI - New medical device coating mouth gel for temporary relief of teething symptoms: a pilot randomised, open-label, controlled study. AB - BACKGROUND: This study verified the feasibility of the monthly recruitment rate, tested the Face, Legs, Activity, Cry and Consolability Pain Assessment Tool (FLACC) for pain in infants and collected preliminary efficacy and safety data of a new proprietary oral gel formulation of high-molecularweight hyaluronan (HMWHA) for the relief of teething. Results will support the design a future main trial vs local anaesthetic, that is currently the only clinically proven pain reliever. METHODS: This was a pilot, randomised, controlled, multicentre, open-label, parallel-group trial. It was performed in two Romanian clinics recruiting infants from 3 to 36 months. Teething diagnosis was based on a minimum of three symptoms such as: local pain, swelling, erythema, hyper salivation and depth characteristics of unerupted tooth. Absence of subcutaneous mucosal laceration was also required. The children were assigned either to HMWHA (HABPX V 3.3, Bioplax Ltd, UK), or to standard drug (Dentinox(r)-Gel N) and treated for 7 consecutive days. Investigators recorded the primary endpoints: swelling, redness and pain (by FLACC method), on days 0, 3 and 7. Changes in crying, mouth spasms, salivation, local pain, swelling, and redness were the secondary endpoints, recorded daily by the parents, on diary cards. Tolerability was assessed on day 14, too. RESULTS: 27 Infants were allocated in HMWHA, and 30 in standard drug. Enrolment rate was 9 patients/month/site. A significant reduction for HMWHA group was evidenced in pain, swelling (from day 0 to 7, p = 0.034 between groups), redness (from day 0 to 3, p = 0.045 and from day 0 to 7, p < 0.001 between groups) and confirmed by the parents' diary records. Pain measurements obtained by FLACC method are consistent with the data belonging to other parameters. Investigator's global assessment of performance was in favour of the HMWHA (p < 0.005). Only two patients, both belonging to standard drug group, experienced adverse events (fever, not related to treatment) and dropped out of the study. CONCLUSIONS: The results solve the feasibility questions and clearly evidence the performance of HABPX V 3.3 in teething symptoms, exceeding the objectives of a simple pilot trial to some extent. Coating oral gels containing HMWHA could be a therapeutic solution for both parents and physicians in managing the irritation and pain resulting from tooth eruption in children.

PMID- 30299031 TI - Outcomes of infants born near term: not quite ready for the "big wide world"? AB - Until recently, there has been a strongly held belief on the part of neonatal and paediatric clinicians that outcomes for infants born close to term are not different from those of babies born at full term. In the last decade, however, this assumption has been challenged by reports suggesting that this is not correct, and highlighting differences in morbidity and mortality both in the short and long term. This has led to development of new terminology to more accurately reflect the impact of immaturity associated with birth at 32-33 weeks (moderately preterm) and 34-36 weeks (late preterm) of gestation. These babies account for around 5-7% of all births and more than 75% of the preterm births in developed countries, so this new recognition of the associated increase in adverse outcomes may have a substantial impact on health care services. This review article will discuss the changing perceptions and concepts of gestational age in the preterm population, and explore the recent and emerging evidence around neonatal, early childhood, school-age, adolescent and adult outcomes for babies who are born moderately preterm and late preterm. It highlights important neonatal and childhood morbidities, and will summarise associated health care, developmental and educational problems of affected children. The implications for the provision of ongoing primary and secondary health care, educational and social support to this large and heterogeneous Group of individuals will be discussed.

AB - The study dealt with etiological diagnostics of bacterial exacerbations of chronic obstructive pulmonary disease (COPD). Samples of bronchial secretion were obtained from 73 patients hospitalized in connection with COPD exacerbations and investigated by the culture method and PSR. The former technique revealed bacterial pathogens in 64 (82%) patients. Gram-positive bacteria (Streptococcus pneumoniae) predominated in patients with stage I and II COPD, Gram-negative (Pseudomonas aeruginosa) and mixt infection in those with stage III and IV COPD. CPR proved more sensitive for isolation of DNA of Gram-negative pathogens (Haemophilus influenzae and Enterobacteriaceae). PMID- 30299034 TI - Oral Pathology Quiz #92. Case number 1.

AB - Inhibitory coagulopathy is a rare variant of hemorrhagic syndrome. Acquired hemophilia A is caused by the formation of inhibitors (antibodies) to Factor VIII of the blood coagulation system leading to impaired activation of the key stage of blood clotting (factor X) and development of hemorrhagic syndrome of different severity. Acquired hemophilia A is a rare disease with an incidence of 1.38-1.48 per 1 million population per year. We report a case off severe idiopathic acquired hemophilia A in a 53 year-old woman manifest as skin hemorrhages, subcutaneous and intramuscular hematomas. Hemostatic therapy described in the article resulted in the elimination of hemorrhagic syndrome and complete remission. This case represents a rare disease the knowledge of which can be useful for preventing the development of debilitating complications, and sometimes saving the patient's life.

PMID- 30299042 TI - Optimal settings for childbirth. AB - Many studies highlight how health is influenced by the settings in which people live, work, and receive health care. In particular, the setting in which childbirth takes place is highly influential. The physiological processes of women's labor and birth are enhanced in optimal ("salutogenic," or health promoting) environments. Settings can also make a difference in the way maternity staff practice. This paper focuses on how positive examples of Italian birth places incorporate principles of healthy settings. The "Margherita" Birth Center in Florence and the Maternity Home "Il Nido" in Bologna were purposively selected as cases where the physical-environmental setting seemed to reflect an embedded model of care that promotes health in the context of childbirth. Narrative accounts of the project design were collected from lead professional and direct inspections performed to elicit the key salutogenic components of the physical layout. Comparisons between cases with a standard hospital labor ward layout were performed. Cross-case similarities emerged. The physical characteristics mostly related to optimal settings were a result of collaborative design decisions with stakeholders and users, and the resulting local intention to maximize safe physiological birth, psychosocial wellbeing, facilitate movement and relaxation, prioritize space for privacy, intimacy, and favor human contact and relationships. The key elements identified in this paper have the potential to inform further investigations for the design or renovation of all birth places (including hospitals) in order to optimize the salutogenic component of any setting in any country.

It is concluded that mucous microflora plays an important factor in the development ofpathology but H.pylori is not its predominant component. Modern classifications of chronic gastritis provide a basis for a deeper insight into evolution of chronic gastritis and its transformation into cancer. The diagnosis of 'chronic gastritis with functional gastroduodenal dyspepsia syndrome' is invalid.

AB - A complex of Ag/AgCl nanoparticles was synthesized on the basis of the extracellular polysaccharide of Azotobacter chroococcum XU1 and 10 mM AgNO3 solution. The complex was characterized by UV spectroscopy, X-ray diffraction, and scanning electron microscopy. Colloidal solutions of the complex had absorption peaks at 260 and 420 nm, indicating the formation Ag/AgCl nanoparticles. The size of the nanoparticles varied from 6 to 50 nm. The nanobiocomposite consisting of the exopolysaccharide matrix and Ag/AgCl nanoparticles exhibited a fungicidal effect against such plant pathogens as Fusarium oxysporum f. sp. vasinfectum and Verticillium dahliae.

AB - Rehabilitation, adaptation, and social integration of the disabled are the priority issues of social welfare policy in the Russian Federation. This includes the enhancement of availability ofphysical education and adapted sports programs. One of the best practices for the improvement ofphysical activity among the population is the "Ready for labour and defense" training system (GTO). However, it is not adapted for those with physical challenges and disabilities. To involve this special fraction of the population in physical activity and participation in the GTO system, disability groups eligible for this activity need to be identified. They can include individuals with visual (VI), intellectual (II), hearing (HI), and locomotor problems as well as those with transplanted organs (TO). Also, minimum disability criteria (MDC) for the participants from each group which would make them eligible to practice an adapted GTO system should be defined. The development of MDC for individuals with VI, II, HI, and TO is relatively easy as they are common for most adapted sports. However, it remains a challenge for persons with locomotor problems since they make up a very diverse group bearing in mind that the rules of the International Paralympic Committee envisage different MDC for different adapted sports. There are two possible solutions: (1) to develop specialized MDC for each sport discipline included in the GTO system, (2) to develop universal MDC for all disciplines. The next step in promoting the GTO system among individuals with physical challenges and disabilities will be the development of the para- GTO program that would be unique and adapted for all categories of the disabled individuals.

AB - Ability of actinobacteria Rhodococcus opacus 1CP to survive under unfavorable conditions and retain its biodegradation activity was assessed. The morphological and ultrastructural features of R. opacus 1CP cells degrading benzoate in the presence of oxidants and stress-protecting agents were investigated. The cells of R. opacus 1CP were resistant to oxidative stress caused by up to 100 mM H2O2 or up to 25 MUM juglone (5-oxy-1,4-naphthoquinone). After 2 h of stress impact, changes in the fatty acid composition, increased activity of antioxidant enzymes, and changes in cell morphology and ultrastructure were observed. The strain retained its ability to degrade benzoate. Quercetin had a protective effect on benzoate-degrading cells of R. opacus 1CP. The strategy for cells survival under unfavorable conditions was formulated, which includeddecreased cell size/volume and formation of densely-packed cell conglomerates, in which the cells are embedded into a common matrix. Formation of conglomerates may probably be considered as a means for protecting the cells against aggressive environmental factors. The multicellular conglomerate structure and the matrix material impede the penetration of toxic substances into the conglomerates, promoting survival of the cells located inside.

PMID- 30299063 TI - [The Factor Stabilizing the Bioluminescence of PVA-Immobilized Photobacteria]. AB - Immobilization of photobacteria in the cryogel of polyvinyl alcohol (PVA) was carried out. Immobilization was found to result in increased intensity and stability of bioluminescence. The elements determining the stability of bioluminescence were investigated. Selection of the strain was found to be of the highest importance. Among immobilized cells, Photobacterium phosphoreum exhibited the most intense and prolonged light emission, while Vibrio harveyi showed the least one. The technological procedures for cryogenic immobilization of photobacteria were determined. The role of the environment of gel formation in the preservation of the bioluminescence activity was determined. In the gels formed in rich medium for submergedcultivation of photobacteria, almost 100% luminescence activity was preserved, while light emission was considerably prolonged. Bioluminescence intensity of the preparations was shown to depend significantly on pH of the incubation medium. The pH shift to acidic values during prolonged incubation of immobilized cells was shown to be one of the factors of bioluminescence quenching. The stress effects of cryogenic immobilizationwere found to have an insignificant effect on the temperature profile of bioluminescence. Decreased reduction rate of the luciferase flavin substrate was shown to be a possible reason for bioluminescence quenching.

AB - Psychoemotional stress is one of the leading cardiovascular risk factors. The aim of this study was to explore manifestations of arterial hypertension (AH) in young men employed in the stress associatedfield works. Material and methods. A total of 68 young men, exposed to job stress (JS) of different severity during 1 to 5 years were surveyed. The control group was formed of persons whose daily work was unrelated to operational activities. The study included ambulatory monitoring (AM) blood pressure (BP) on different days of the week, comparing the results of the office and DMBP determination and assessment of resistance to a variety of diagnostic loads. Results. The study revealed an increase of AMBP indicators during the working day and their normalization at weekend. The comparison of the results of office and ambulatory determination of BP demonstrated that different forms of stressful AH (stable, isolated office and latent) occurred significantly more often than in the control group. These changes almost completely disappeared at weekends. The tolerance ofpsychoemotional testing was much worse than that of traditional exercises. It is proposed to more extensively use AMBP during regular medical examinations of young men exposed to JS in order to establish a timely differential diagnosis of various forms of stressful hypertension. PMID- 30299066 TI - [Model of the Regulation of Activity of Immobilized Enzymes (Amylases) in Soil]. AB - The preservation of activity of extracellular enzymes in soil is presently associated with their immobilization on organic or inorganic carriers. Enzyme immobilization results, however, in a significant decrease in enzymatic activity. In the present work, the mechanism responsible for promotion of the catalytic activity was revealed, as well as the favorable effect of low-molecular alkylhydrozybenzenes of the class of alkylresorcinols, which are common in soil organic matter, on stability of immobilized enzymes (exemplified by amylases) by their post-translational modification. Optimal conditions (enzyme to sorbent ratio, pH optimum, CaCl2 concentration, and sorption time) for amylase sorption on a biological sorbent (yeast cell walls) were determined and decreased activity of the immobilized enzyme compared to its dissolved state was confirmed. Alkylresorcinols (C7AHB) at concentrations of 1.6 to 80 mM were found to cause an increase of amylase activity both in the case of already sorbed enzymes (by 30%) and in the case of a free dissolved enzyme with its subsequent immobilization (by 50-60%). In both cases, the optimal C7AHB concentration was16 mM. Amylase stability was determined for C7AHB-modified and unmodified enzymes immobilized on the biological sorbent after two cycles of freezing (-20 degrees C) and thawing (4 degrees C). Inverse dependence was revealed between increasing stability of C7AHB-modified enzymes and an increase in their activity, as well as higher stability of immobilized modified amylases than of the dissolved modified enzyme. Investigation of the effect of C7HOB-modification in the preservation of activity in immobilized amylases after four freeze-thaw cycles revealed: (1) better preservation of activity by the modified immobilized enzymes compared to immobilized ones; (2) differences in the dynamics of activity loss within compared pairs, with activity ofimmobilized amylases decreasing after the second cycle to a lower level (42%) than activity of the modified immobilized enzymes after the fourth cycle (48%). These results demonstrate that in the preservation of activity of extracellular enzymes in soil both stabilization mechanisms are of importance: immobilization on organic carriers and modification of the enzyme conformation by low-molecular compounds with the functions of chemical chaperones.

AB - Aim: To study the character, prevalence, and typological structure of atherosclerotic changes in major arteries by multislice computed tomography in patients with various metabolic disorders. Material and Methods: Carotid arteries of 78 patients with metabolic syndrome or type 2 diabetes mellitus and without carbohydrate metabolism disorders were examined by multislice computed tomography. Results: The study revealed various types of atherosclerotic plaques differing in the composition of lipid, lipid-fibrotic and calcium components. The latter were especially well expressed in diabetes. Conclusion: All types of atherosclerotic plaques are roughly equally represented in the structure of atherosclerotic lesions of carotid arteries in patients with metabolic syndrome in the absence of type 2 diabetes. Diabetic patients had vascular lesions with especially high density of atherosclerotic plaques. PMID- 30299067 TI - [The risk of cardiovascular death in type 2 diabetes]. AB - Aim: To evaluate effects of metabolic disorders on the risk of cardiovascular death in patients with type II diabetes based on Framingham risk score. We analyzed results of examination of 210 men and 210 women with type 2 diabetes who applied for medical care to the VM center of Endocrinology during 1997-2014. A virtual control group was formed matching real patients in terms of the number, sex, age, and height having ideal body mass index, total cholesterol and high density lipoprotein cholesterol levels. The average risk of cardiovascular death in patients with type 2 diabetes was equal to 4,56+/-0,254% compared with 0,6+/ 1,028% in the virtual control group. The differences was significant (p <0,001). The minimum risk for the patients of the two groups was estimated at 0,001% and 0,01% respectively. The maximum risk of cardiovascular death is 34,17% in patients with diabetes and 8,24% in controls. It is concluded that type 2 diabetes and related metabolic disorders significantly increase the risk of cardiovascular death.

AB - We studied the influence of activation ofpecilomycotic infection in blood on the morphofunctional state of myocardium based on the clinical and pathomorphological data. The study included 23 patients with bronchial asthma (BA) concomitant with pecilomycosis after acute viral respiratory infection; protocols of autopsies and pathological sections of the heart muscle of the patients who died from asphixy and acute cardiac insufficiency were analyzed. Histological sections showed up vascular dystonia of the microcirculation bed, arteriole spasms, wall destruction in small and medium-size vessels and the adjacent muscular tissue, stromal oedema, valvular swelling, andperiwall endocarditis. Cardiac cavities and coronary vessels contained erythrocyte-rich thrombi with ferulas of Paecilomyces at different stages of development. Clinical manifestations of destructive changes in the heart muscle developing under effect of Paecilomyces infection had the form of rhythm and conductivity disorders. The local protective inflammatory reaction of productive type had the form of intermediate and vascular-type myocarditis passing to postmyocarditic cardiosclerosis. Periodic bursts of activation ofpecilomycotic infection in blood with the accumulation of fungal phospholipase A2 and lipid metabolites produced membranotoxic effect and can play the key role in the development of atherosclerosis and hypertensive disease in patients with BA and pecilomycosis.

AB - Aim: To analyze the literature data and the results of original studies on the respiratory function in patients with sarcoidosis. Material and methods: The study included 1199 patients with sarcoidosis (67.8% women and 32.2% of males, median age 43 years). The first X-ray stage was documented in 34.8% of patients , stage II in 57.0%, stage III in 6.1%, stage IV in 1.3%, stage 0 in 0.7%. One patient (0.1%) had pleural sarcoidosis. Loefgren syndrome was diagnosed in 20% of the patients. In 658 patients (54.9%) the diagnosis was confirmed by biopsy studies. Results: The patients with sarcoidosis exhibited significant correlation between radiographic and spirometric characteristics. In those with Loefgren syndrome, all breathing parameters were much better than in the remaining ones. Changes of spirometry parameters were more pronounced in smokers and in patients with concomitant lung diseases. However, the lung function remained impaired after adjustment for these factors, and 9,7% of the cases positively responded to the administration of a short-acting bronchodilator. X-ray examination and spirometry are independent methods for the evaluation of the health status of patients with sarcoidosis and their results do not always correlate with each other after different treatment regimens. Changes in X-ray image and lung vital capacity were consistent in patients treated with prednisone, methotrexate and pentoxifylline, but not in the cases treated with vitamin E and in the absence of treatment. Spirometry with simultaneous X-ray examination is recommended for all patients with intrathoracic sarcoidosis. Conclusion: Forced vital capacity of lungs (FVC) is an independent criterion for evaluating the condition of patients with sarcoidosis and the effectiveness of the treatment.

AB - A case of polyorganic insufficiency syndrome associated with coma, convulsive disorder, acute hepato-renal and respiratory dysfunction, hypovolemic shock, and hyperthermal syndrome in a 46 year-old participant ofa marathon competition is reported. The clinical picture was dominated by acute hepatic insufficiency treated with remaxol to activate substrate phosphorylation under effect of exogenous succinate for slowing down the development of energy deficit in mitochondria under condition of oxygen deficit. This case can be regarded as a variant of correction of mitochondrial dysfunction with the use of a mitochondria targeted medication such as succinate-containing remaxol. This medication reduced AST and ALT activities and utilization of endogenous enzymes for succinate synthesis from alanine and aspartate under hypoxic conditions. Prescription of remaxol as a form of direct substitution therapy was dictated by pathogenetic considerations. PMID- 30299073 TI - Nitrogen and Sulfur Co-Doped Graphene Nanosheets to Improve Anode Materials for Sodium-Ion Batteries. AB - Sodium-ion batteries (SIBs) attract more attention because of sodium's abundant availability, affordable price, and potential to be an effective anode material. Meanwhile, carbon-based materials provide the most promising anode materials. Because of the large radius of sodium ions, SIBs do not exhibit favorable electrochemical performance. Introducing heteroatoms into the carbon-lattice is an effective strategy to enlarge the interlayer space of carbon-based materials which can improve carbon's electrochemical performance. In addition, anode materials with a surface-induced capacitive process can enhance the SIB's electrochemical performance because its capacitive process increases the kinetics of ion diffusion. Here, we describe an SIB's anode material containing nitrogen and sulfur co-doped graphene sheets [denoted as poly(2,5-dimercapto-1,3,4 thiadiazole) (PDMcT)/reduced graphene oxide (RGO)] which are synthesized via carbonization of PDMcT polymerized on the surface of GO. PDMcT/RGO exhibited high capacities (240 mA h g-1 at 500 mA g-1), improved rate performance (144 mA h g-1 at 10 A g-1), and good cycling stability (153 mA h g-1 after 5000 cycles at 5000 mA g-1). These unique results are attributed to the enlarged interlayer spacing and electronic conductivity from the heteroatoms which facilitate the sodium ion's insertion and electron transport. These results represent that PDMcT/RGO is a great potential anode material for SIBs. PMID- 30299074 TI - Effect of Carboxylic Acid-Doped Carbon Nanotube Catalyst on the Performance of Aqueous Organic Redox Flow Battery Using the Modified Alloxazine and Ferrocyanide Redox Couple. AB - Alloxazine and ferrocyanide are suggested as the redox couple for an aqueous organic redox flow battery (AORFB). Alloxazine is further modified by carboxylic acid (COOH) groups (alloxazine-COOH) to increase the aqueous solubility and to pursue a desirable shift in the redox potential. For obtaining a better AORFB performance, the overall redox reactivity of AORFB should be improved by the enhancement of the rate-determining reaction of the redox couple. A carboxylic acid-doped carbon nanotube (CA-CNT) catalyst is considered for increasing the reactivity. The utilization of CA-CNT allows for the induction of a better redox reactivity of alloxazine-COOH because of the role of COOH within alloxazine-COOH as a proton donor, the fortified hydrophilic attribute of alloxazine-COOH, and the increased number of active sites. With the assistance of these attributes, the mass transfer of aqueous alloxazine-COOH molecules can be promoted. However, CA-CNT does not have an effect on the increase of the redox reactivity of ferrocyanide because the redox reaction is not affected by the same influence of protons that the redox reactivity of alloxazine-COOH is affected by. Such a behavior is proven by measuring the electron transfer rate constant and diffusivity. With regard to AORFB full cell testing, when CA-CNT is used as a catalyst for the negative electrode, the performance of the AORFB increases. Specifically, the charge-discharge overpotential and infrared drop potential are improved. As a result, the voltage efficiency affected by the potentials increases to 64%. Furthermore, the discharging capacity reaches 26.7 A h.L-1, and the state of charge attains 83% even after 30 cycles.

In this article, we report a nanocomposite of anatase titania nanoparticles (TiO2-NPs), carbon nanotubes, and carbon nanofibers as a freestanding gas diffusion cathode for Li CO2 batteries. Nanostructured anatase TiO2 is demonstrated as a low-cost, easy-to synthesize catalyst for CO2 capture and utilization.

AB - This paper presents the synthesis of highly biocompatible and biodegradable poly lactide-co-glycolide (PLGA) microchamber arrays sensitive to low-intensity therapeutic ultrasound (1 MHz, 1-2W, 1 min). A reliable method was elaborated that allowed the microchambers to be uniformly filled with epinephrine hydrochloride (EH), with the possibility of varying the cargo amount. The maximum load of EH was 4.5 MUg per array of 5 mm x 5 mm (about 24 pg of EH per single microchamber). A gradual, spontaneous drug release was observed to start on the first day, which is especially important in the treatment of acute patients. Ultrasound triggered a sudden substantial release of EH from the films. In vivo real-time studies using a laser speckle contrast imaging system demonstrated changes in the hemodynamic parameters as a consequence of EH release under ultrasound exposure. We recorded a decrease in blood flow as a vascular response to EH release from a PLGA microchamber array implanted subcutaneously in a mouse. This response was immediate and delayed (one and two days after the implantation of the array). The PLGA microchamber array is a new, promising drug depot implantable system that is sensitive to external stimuli.

AB - As a novel and potential transition metal dichalcogenide (TMDC), NbSe2 has low ion diffusion barrier when applied in energy-storage systems, such as traditional lithium-ion batteries and novel magnesium-ion batteries (MIBs). In this work, we have developed a novel hexagonal NbSe2 material with a nanosized surface via a facile microwave-hydrothermal method. The Li+-storage mechanism of NbSe2 with surface conversion and internal intercalation is thoroughly revealed by in situ X ray diffraction (XRD), ex situ high-resolution transmission electron microscopy, and ex situ scanning electron microscopy. Besides, Mg2+ intercalation mechanism is confirmed via ex situ XRD and ex situ X-ray photoelectron spectroscopy for the first time. In addition, as the cathode for MIBs, NbSe2 with a nanosized surface exhibits a high rate capacity of 101 mA h g-1 at 200 mA g-1 with a high discharge plateau at 1.30 V. Our work builds a deep understanding of ion-storage mechanisms in TMDCs and provides guidance for designing new electrode materials with high electrochemical performances. PMID- 30299078 TI - Abrupt Thermal Shock of (NH4)2Mo3S13 Leads to Ultrafast Synthesis of Porous Ensembles of MoS2 Nanocrystals for High Gain Photodetectors. AB - Ultrafast synthesis of high-quality transition-metal dichalcogenide nanocrystals, such as molybdenum disulfide (MoS2), is technologically relevant for large-scale production of electronic and optoelectronic devices. Here, we report a rapid solid-state synthesis route for MoS2 using the chemically homogeneous molecular precursor, (NH4)2Mo3S13.H2O, resulting in nanoparticles with estimated size down to 25 nm only in 10 s at 1000 degrees C. Despite the extreme nonequilibrium conditions, the resulting porous MoS2 nanoparticles remain aggregated to preserve the form of the original rod shape bulk morphology of the molecular precursor. This ultrafast synthesis proceeds through the rapid decomposition of the precursor and rearrangement of Mo and S atoms coupled with simultaneous efficient release of massive gaseous species, to create nanoscale porosity in the resulting isomorphic pseudocrystals, which are composed of the MoS2 nanoparticles. Despite the very rapid escape of massive amounts of NH3, H2O, H2S, and S gases from the (NH4)2Mo3S13.H2O mm sized crystals, they retain their original shape as they convert to MoS2 rather than undergo explosive destruction from the rapid escape process of the gases. The obtained pseudocrystals are made of aggregated MoS2 nanocrystals exhibit a Brunauer-Emmett-Teller surface area of ~35 m2/g with an adsorption average pore width of ~160 A. The nanoporous MoS2 crystals are solution processable by dispersing in ethanol and water and can be cast into large-area uniform composite films. Photodetectors fabricated from these films show more than 2 orders of magnitude higher conductivity (~6.25 * 10-6 S/cm) and photoconductive gain (20 mA/W) than previous reports of MoS2 composite films. The optoelectronic properties of this nanoporous MoS2 imply that the shallow defects that originate from the ultrafast synthesis act as sensitizing centers that increase the photocurrent gain via two-level recombination kinetics. PMID- 30299079 TI - Distinguishing Core and Antenna Fucosylated Glycopeptides Based on Low-Energy Tandem Mass Spectra. AB - A straightforward approach has been developed to distinguish core and antenna fucosylation in glycopeptides. The method does not require derivatization and can be easily adapted into a proteomics workflow. The key aspect is to use low collision energy collision-induced dissociation (CID) (on a quadrupole time-of flight type instrument) when only single-step fragmentation processes occur. Low collision energy should show the precursor ion as the largest peak in the spectrum; the survival yield should be ideally over 50%, and this is obtained at a collision energy ca. 30% of that typically used for proteomics. In such a case, interfering processes like fucose migration or consecutive reactions are minimized. Core and antenna fucosylation can be discriminated using various ion abundance ratios. Low-energy CID spectra are very "clean" (no chemical noise), and the ions used for locating the fucose are among the major peaks, making the method well-suited for analytical work. Monitoring the change in the proportion of core and antenna fucosylation at the same glycosylation site is also feasible. PMID- 30299080 TI - Induced Aggregation and Synergistic Coordination Strategy in Cluster Organic Architectures. AB - Developments in strategies for the synthesis of oxo-hydroxo lanthanide (Ln) clusters during the past few decades have resulted in abundant relevant crystalline materials that exhibit attractive structures and interesting properties. The combination of these oxo-hydroxo Ln clusters and organic ligands has led to the formation of new extended arrays of Ln cluster organic frameworks (LnCOFs). In contrast to metal-organic frameworks, the incorporation of particular characteristics of clusters provides the opportunity to develop performances not available in single-metal compounds. Even with steady advances in oxo-hydroxo Ln clusters, progress in LnCOFs is less developed. To obtain LnCOFs, one premise is to induce the oxophilic Ln ions undergoing aggregation. Meanwhile, the organic ligands should have extra coordination sites for further expansion. Multidentate organic ligands like pyrazinecarboxylic acid and pyridinecarboxylic acid containing O and N donors will meet these two requirements. Their carboxyl groups will induce the aggregation of Ln ions, while the N donors can serve as potential extension sites. To make more open frameworks or if the oxo-hydroxo Ln clusters fail to be congregated or connected, then a second ligand is necessary. The introduction of the suitable second ligand may occupy a partial coordination sphere of Ln ions and ultimately benefit the connection process. In this Account, we introduce the origin and evolution of the induced aggregation and synergistic coordination strategy. According to the attributes of the organic ligands in the documented LnCOFs, we classify them into linear and nonlinear groups in the second and third parts. From the aspect of ligand-induced aggregation, isonicotinic acid (HIN) and lengthened 4-(4 pyridyl)benzoic acid (HPBA) ligands as well as their nonlinear analogues are settled as typical models. From the aspect of synergistic coordination, chelating ligands like 1,2-benzenedicarboxylic acid (1,2-H2BDC) and acetic acid (HOAc) play significant roles. Moreover, three types of synergistic coordination are discussed in detail: synergistic coordination between two types of organic ligands, synergistic coordination between organic and inorganic ligands, and simultaneous synergistic coordination of aforementioned two types. From the aspect of LnCOF products, in addition to traditional pure LnCOFs, new types of heterometallic frameworks containing two types of cluster building units have been developed. Although this Account focuses on the nuclearity and coordination aspects of LnCOFs, we anticipate that it will stimulate more efforts in the further study of their properties beyond the exploratory synthesis. More importantly, synergistic coordination may be applied to other systems and inspire crystal design and targeted assembly of new functional materials. PMID- 30299081 TI - "Reverse Kendrick Mass Defect Analysis": Rotating Mass Defect Graphs to Determine Oligomer Compositions for Homopolymers. AB - A new approach to determining the repeat unit compositions of homopolymers is reported in which a mass defect graph is rotated to zero slope to give a graph identical to a Kendrick mass defect graph. Because the Kendrick mass defect (KMD) is directly related to the elemental composition of the base unit, the process can be reversed. A mass defect graph (fractional m/ z plotted against exact m/ z) of a homopolymer can be rotated until the slope of the data points is zero. This is equivalent to finding a new constant factor by which the measured exact masses would have to be multiplied to create a Kendrick mass defect graph with zero slope. The elemental composition of the repeat unit can be determined by matching the new factor against the calculated factors for candidate compositions. This approach provides some benefits over simply looking for pairs of peaks corresponding to oligomer units. The primary benefit is to assist in visualization of the data. Rotating the data points corresponding to polymer masses to zero slope makes it easier to visualize the polymer data, and it facilitates the graphical isolation of polymer masses from background interferences. The repeat unit composition is determined not from a single pair of peaks but from multiple data points, and systematic errors in mass assignment can be visualized as deviations from linearity. Resolution-enhanced KMD graphs can be constructed for the calculated repeat unit composition by using fractional base units. PMID- 30299082 TI - Progress toward Solid State Synthesis by Design. AB - Ages of history are defined by the underlying materials that promoted human development: stone, bronze, and iron ages. Since the middle of the last century, humanity has lived in a silicon age, where the development of the transistor ushered in new technologies previously thought inconceivable. But as technology has advanced, so have the requirements for new materials to sustain increasing physical demands. The field of solid state chemistry is dedicated to the discovery of new materials and phenomena, and though most materials discoveries in history have been through serendipity rather than careful reaction design, the last few decades have seen an increase in the number of materials discovered through a consideration of chemical reaction kinetics and thermodynamics. Materials by design have changed the way solid state chemists approach the synthesis of possible materials with interesting and useful properties. Unlike other chemistry subfields such as organic chemistry and biochemistry, solid state chemistry does not currently benefit from a toolbox of reactions that can allow for the synthesis of any arbitrary material. The diversity and complexity of the solid state phase space likely inhibits chemists from ever having such a toolbox. However, a thorough understanding of the various synthetic techniques involved in the synthesis of stable and metastable solids may be realized through an understanding of the reaction kinetics and thermodynamics. In the Account, we review the common synthesis techniques involved in the formation of metastable materials and break down their underlying chemistry to the simplest reaction mechanisms involved. The synthesis reactions of most metastable materials can be understood through these three reaction driving parameters, which include the exploitation of Le Chatelier's principle, thermo-kinetic reaction coupling, and lowering the activation energy of formation of the metastable product, and we identify several materials whose syntheses are described either by one or a combination of these driving parameters. We identify what exists at the frontier of materials discovery by design, including novel applications of supercritical fluids for tuning between "gas" and "solvent"-like environments. While conventional solvation requires changes in either the temperature or composition of the system, supercritical fluid solvation requires only changes in the fluid density, which opens up the possibilities for the synthesis of new materials. Most importantly, however, we look toward the future of materials synthesis by design and see that it must be a collaborative one. At present, chemists design materials using knowledge about chemical structure and reactivity but often target specific materials with very specific properties. In contrast, computational chemists perform calculations on millions of different elemental combinations and find many candidates of possible materials with interesting properties, though most of these are not realizable synthetically due to limitations in reactivity, kinetics, or thermodynamics. Synthetic harmony can be achieved through active collaboration and communication between these two subfields of chemistry, such that new calculations can incorporate complete knowledge about reaction kinetics and thermodynamics, and new syntheses target computationally predicted materials derived from an understanding of mapped reaction landscapes.

AB - We report a procedure to fabricate glass-insulated carbon fiber ultramicroelectrodes (CF UMEs) with sizes of 10 and 1 MUm in diameter. CF UMEs of theses sizes are commonly insulated with polymer or epoxy resins, which typically have pinholes and are less stable and difficult to polish. Through judicious choice of polishing materials, the fabrication procedure reported here leads to CF UMEs with a surface geometry that, within experimental error, is close to that of an inlaid disk. We demonstrate how the hardness factor of commonly used polishing materials may alter the geometry of CF UMEs, in which carbon has a larger hardness factor compared to other metals (i.e., Pt or Au). Atomic force microscopy (AFM) and steady-state voltammetry (SSV) were used to characterize the CF UME surface and record the electrochemical response, respectively. These results were compared to theoretical values for an inlaid disk UME. Pt nanoparticle (NP) collision experiments using electrocatalytic amplification were used to deposit an exact number of Pt NPs on a CF UME surface. Surface roughness was found to significantly decrease the sticking of Pt NPs on the CF surface, compared to the theoretical collision frequency. However, decreasing surface roughness through judicious polishing led to good agreement between experimental and theoretical collision frequencies of NPs on a CF UME surface, leading to the fabrication of NP ensembles of UME dimensions (UME-NPE) and a single-nanoparticle UME (SNP-UME). These electrodes were used to record and analyze SSVs for the hydrogen evolution reaction (HER) in acidic media. PMID- 30299085 TI - Stimuli-Responsive Therapeutic Metallodrugs. AB - The success of platinum-based anticancer agents has motivated the exploration of novel metal-based drugs for several decades, whereas problems such as drug resistance and systemic toxicity hampered their clinical applications and efficacy. Stimuli-responsiveness of some metal complexes offers a good opportunity for designing site-specific prodrugs to maximize the therapeutic efficacy and minimize the side effect of metallodrugs. This review presents a comprehensive and up-to-date overview on the therapeutic stimuli-responsive metallodrugs that have appeared in the past two decades, where stimuli such as redox, pH, enzyme, light, temperature, and so forth were involved. The compounds are classified into three major categories based on the nature of stimuli, that is, endo-stimuli-responsive metallodrugs, exo-stimuli-responsive metallodrugs, and dual-stimuli-responsive metallodrugs. Representative examples of each type are discussed in terms of structure, response mechanism, and potential medical applications. In the end, future opportunities and challenges in this field are tentatively proposed. With diverse metal complexes being introduced, the foci of this review are pointed to platinum and ruthenium complexes. PMID- 30299084 TI - Expanded Substrate Scope of DNA Polymerase theta and DNA Polymerase beta: Lyase Activity on 5'-Overhangs and Clustered Lesions. AB - DNA polymerase theta (Pol theta) is a multifunctional enzyme with double-strand break (DSB) repair, translesion synthesis, and lyase activities. Pol theta lyase activity on ternary substrates containing a 5'-dRP that are produced during base excision repair of abasic sites (AP) is weak compared to that of DNA polymerase beta (Pol beta), a polymerase integrally involved in base excision repair. This led us to explore whether Pol theta utilizes its lyase activity to remove 5'-dRP and incise abasic sites from alternative substrates that might be produced during DNA damage and repair. We found that Pol theta exhibited lyase activity on abasic lesions near DSB termini and on clustered lesions. To calibrate the Pol theta activity, Pol beta reactivity was examined with the same substrates. Pol beta excised 5'-dRP from within a 5'-overhang 80 times faster than did Pol theta. Pol theta and Pol beta also incised AP within clustered lesions but showed opposite preferences with respect to the polarity of the lesions. AP lesions in 5' overhangs were typically excised by Pol beta 35-50 times faster than those in a duplex substrate but 15-20-fold more slowly than 5'-dRP in a ternary complex. This is the first report of Pol theta exhibiting lyase activity within an unincised strand. These results suggest that bifunctional polymerases may exhibit lyase activity on a greater variety of substrates than previously recognized. A role in DSB repair could potentially be beneficial, while the aberrant activity exhibited on clustered lesions may be deleterious because of their conversion to DSBs. PMID- 30299086 TI - Nanocellulose toward Advanced Energy Storage Devices: Structure and Electrochemistry. AB - Cellulose is the most abundant biopolymer on Earth and has long been used as a sustainable building block of conventional paper. Note that nanocellulose accounts for nearly 40% of wood's weight and can be extracted using well developed methods. Due to its appealing mechanical and electrochemical properties, including high specific modulus (~100 GPa/(g/cm3)), excellent stability in most solvents, and stability over a wide electrochemical window, nanocellulose has been widely used as a separator, electrolyte, binder, and substrate material for energy storage. Additionally, nanocellulose-derived carbon materials have also drawn increasing scientific interest in sustainable energy storage due to their low-cost and raw-material abundance, high conductivity, and rational electrochemical performance. The inexpensive and environmentally friendly nature of nanocellulose and its derivatives as well as simple fabrication techniques make nanocellulose-based energy storage devices promising candidates for the future of "green" and renewable electronics. For nanocellulose based energy storage, structure engineering and design play a vital role in achieving desired electrochemical properties and performances. Thus, it is important to identify suitable structure and design engineering strategies and to better understand their relationship. In this Account, we review recent developments in nanocellulose-based energy storage. Due to the limited space, we will mainly focus on structure design and engineering strategies in macrofiber, paper, and three-dimensional (3D) structured electrochemical energy storage (EES) devices and highlight progress made in our group. We first present the structure and properties of nanocellulose, with a particular discussion of nanocellulose from wood materials. We then go on to discuss studies on nanocellulose-based macrofiber, paper, and 3D wood- and other aerogel-based EES devices. Within this discussion, we highlight the use of natural nanocellulose as a flexible substrate for a macrofiber supercapacitor and an excellent electrolyte reservoir for a breathable textile lithium-oxygen battery. Paper batteries and supercapacitors using nanocellulose as a green dispersant, nanocellulose-based paper as a flexible substrate, and nanocellulose as separator and electrolyte are also examined. We highlight recent progress on wood-based batteries and supercapacitors, focusing on the advantages of wood materials for energy storage, the structure design and engineering strategies, and their microstructure and electrochemical properties. We discuss the influence of structure (particularly pores) on the electrochemical performance of the energy storage devices. By taking advantage of the straight, nature-made channels in wood materials, ultrathick, highly loaded, and low-tortuosity energy storage devices are demonstrated. Finally, we offer concluding remarks on the challenges and directions of future research in the field of nanocellulose-based energy storage devices. PMID- 30299087 TI - Rationally Optimized Fluorescent Probe for Imaging Mitochondrial SO2 in HeLa Cells and Zebrafish. AB - Organisms have built up immunological systems, where mitochondrial SO2 plays conflicting roles in regulating cell apoptosis. However, no exploration on the influence and regulating principle of mitochondrial SO2 to the specific apoptosis type can be found, which brings about a challenge to fluorescent probes. Herein, we optimize the fluorophore and develop a new fluorescent probe FHMI (( E)-4-(3 formyl-4-hydroxystyryl)-1-methylpyridin-1-iumiodide) by equipping an ICT (intramolecular charge transfer) fluorophore HMII (( E)-4-(4-hydroxystyryl)-1 methylpyridin-1-ium iodide) with an aldehyde group that serves as both fluorescence quencher and reporting group. After the optimization, although the nonconjugated electron donor is formed when sensing SO2, the preset ICT fluorophore HMII is permitted to release the fluorescence at the enlarged wavelength. Compared with the traditional design, the probe FHMI exhibits obvious enhanced fluorescence with large red shift. FHMI is successfully applied to the mechanistic exploration of the dichotomous effects of mitochondrial SO2 to cells apoptosis, showing that mitochondrial SO2 regulates the early apoptosis of HeLa cells via the reduction of mitochondrial membrane potential. FHMI is applied to explore the dichotomous bioinfluence of mitochondrial SO2 to HeLa cells under oxidative stress, visualizing the regulative role of mitochondrial SO2 in the apoptotic process. For the first time, the mitochondrial SO2 is visually found to be closely associated with the early apoptosis of HeLa cells. Moreover, FHMI proves to be readily applicable to monitoring endogenous SO2 in zebrafish. This probe can act as an effective optical tool for exploring SO2 in biospecimen. PMID- 30299088 TI - Radioactive Transition Metals for Imaging and Therapy. AB - Nuclear medicine is composed of two complementary areas, imaging and therapy. Positron emission tomography (PET) and single-photon imaging, including single photon emission computed tomography (SPECT), comprise the imaging component of nuclear medicine. These areas are distinct in that they exploit different nuclear decay processes and also different imaging technologies. In PET, images are created from the 511 keV photons produced when the positron emitted by a radionuclide encounters an electron and is annihilated. In contrast, in single photon imaging, images are created from the gamma rays (and occasionally X-rays) directly emitted by the nucleus. Therapeutic nuclear medicine uses particulate radiation such as Auger or conversion electrons or beta- or alpha particles. All three of these technologies are linked by the requirement that the radionuclide must be attached to a suitable vector that can deliver it to its target. It is imperative that the radionuclide remain attached to the vector before it is delivered to its target as well as after it reaches its target or else the resulting image (or therapeutic outcome) will not reflect the biological process of interest. Radiochemistry is at the core of this process, and radiometals offer radiopharmaceutical chemists a tremendous range of options with which to accomplish these goals. They also offer a wide range of options in terms of radionuclide half-lives and emission properties, providing the ability to carefully match the decay properties with the desired outcome. This Review provides an overview of some of the ways this can be accomplished as well as several historical examples of some of the limitations of earlier metalloradiopharmaceuticals and the ways that new technologies, primarily related to radionuclide production, have provided solutions to these problems. PMID- 30299089 TI - Highly Active Protein Surfaces Enabled by Plant-Based Polyphenol Coatings. AB - Proteins represent complex biomolecules capable of wide-ranging but also highly specific functionalities. Their immobilization on material supports can enable broad applications from sensing and industrial biocatalysis to biomedical interfaces and materials. We demonstrate the advantages of using aqueous processed cross-linked polyphenol coatings for immobilizing proteins, including IgG, avidin, and various single and multidomain enzymes on diverse materials, to enable active biofunctional structures (e.g., ca. 2.2, 1.7, 1.1, and 4.8 mg.m-2 active phosphatase on nanoporous cellulose and alumina, steel mesh, and polyester fabric, respectively). Enzyme assays, X-ray photoelectron spectroscopy, silver staining, supplemented with contact angle, solid-state 13C NMR, HPLC, and ESI-MS measurements were used to characterize the polyphenols, coatings, and protein layers. We show that the functionalization process may be advantageously optimized directly for protein activity rather than the traditional focus on the thickness of the coating layer. Higher activities (by more than an order of magnitude in some cases) and wider process pH and material compatibility are demonstrated with polyphenol coatings than other approaches such as polydopamine. Coatings formed from different plant polyphenol extracts, even at lowered purity (and cost), were also found to be highly functional. Chemically, our results indicate that polyphenol coatings differ from polydopamine mainly because of the elimination of amine groups, and that polyphenol layers with intermediate levels of reactivity may better lead to high immobilized protein activity. Overall, an improved understanding of simple-to-use polyphenol coatings has been obtained, which enabled a significant development in active protein surfaces that may be applied across diverse materials and nanostructured supports. PMID- 30299090 TI - Nanotubes, Plates, and Needles: Pathway-Dependent Self-Assembly of Computationally Designed Peptides. AB - Computationally designed peptides form desired antiparallel, tetrameric coiled coil bundles that hierarchically assemble into a variety of well-controlled nanostructures depending on aqueous solution conditions. The bundles selectively self-assemble into different structures: nanotubes, platelets, or needle-like structures at solution pH values of 4.5, 7, and 10, respectively. The self assembly produces hollow tubes or elongated needle-like structures at pH conditions associated with charged bundles (pH 4.5 or 10); at neutral pH, near the pI of the bundle, a plate-like self-assembled structure forms. Transmission electron microscopy and small-angle X-ray scattering show the nanotubes to be uniform with a tube diameter of ~13 nm and lengths of up to several MUm, yielding aspect ratios >1000. Combining the measured nanostructure geometry with the apparent charged states of the constituent amino acids, a tilted-bundle packing model is proposed for the formation of the homogeneous nanotubes. This work demonstrates the successful use of assembly pathway control for the construction of nanostructures with diverse, well-structured morphologies associated with the folding and self-association of a single type of molecule. PMID- 30299091 TI - A Langbeinite-Type Yttrium Phosphate LiCs2Y2(PO4)3. AB - Langbeinite-type inorganic compounds have a wide range of applications, but nonlinear-optical properties are rarely mentioned in this series. Here, we report a new orthophosphate, LiCs2Y2(PO4)3, with a langbeinite-type structure, which is the first example in the system of mixed alkali-metal yttrium phosphates. Notably, LiCs2Y2(PO4)3 exhibits a moderate second-harmonic-generation efficiency of 0.9KH2PO4 and is transparent down to 200 nm. In addition, the thermal stability and theory calculations, including the electronic band structure, second-order nonlinear-optical coefficients, and dipole moment analysis, are also reported. This work not only expands the langbeinite-type system but also inspires a study on their nonlinear-optical properties. PMID- 30299092 TI - Laboratory Studies of Vibrational Excitation in O2( a1Deltag, v) Involving O2, N2, and CO2. AB - Collisional removal of electronic energy from O2 in the low-lying a1Deltag state is typically an extremely slow process for the v = 0 level. In this study, we report results on the deactivation of O2( a1Deltag, v = 1-3) in collisions with O2 and CO2. Ozone photodissociation in the 200-310 nm Hartley band is the source of O2( a, v), and resonance-enhanced multiphoton ionization is used to probe the vibrational-level populations. Deactivation of the a( v = 1-3) levels in collisions with O2 at 300 K is fast, with rate coefficients of (5.6 +/- 1.1) * 10 11, (3.6 +/- 0.4) * 10-11, and (1.9 +/- 0.4) * 10-11 cm3 s-1 (2sigma) for v = 1, 2, and 3, respectively. The relaxation process appears to involve a near-resonant electronic energy transfer pathway analogous to that observed in vibrationally excited O2( b1Sigmag+). With CO2 collider gas, the removal rate coefficient at 300 K is (1.8 +/- 0.4) * 10-14 and (4.4 +/- 0.6) * 10-14 cm3 s-1 (2sigma) for v = 1 and 2, respectively. Despite the small mole fraction of O2 in the atmospheres of Mars and Venus, O2 is at least as important as CO2 in the final stages of collisional relaxation within the O2 vibrational-level manifold. PMID- 30299093 TI - Exhaustive Exploration of the Conformational Landscape of Small Cyclic Peptides Using a Robotics Approach. AB - Small cyclic peptides represent a promising class of therapeutic molecules with unique chemical properties. However, the poor knowledge of their structural characteristics makes their computational design and structure prediction a real challenge. In order to better describe their conformational space, we developed a method, named EGSCyP, for the exhaustive exploration of the energy landscape of small head-to-tail cyclic peptides. The method can be summarized by (i) a global exploration of the conformational space based on a mechanistic representation of the peptide and the use of robotics-based algorithms to deal with the closure constraint and (ii) an all-atom refinement of the obtained conformations. EGSCyP can handle D-form residues and N-methylations. Two strategies for the side-chains placement were implemented and compared. To validate our approach, we applied it to a set of three variants of cyclic RGDFV pentapeptides, including the drug candidate Cilengitide. A comparative analysis was made with respect to replica exchange molecular dynamics simulations in implicit solvent. Its results show that the EGSCyP method provides a very complete characterization of the conformational space of small cyclic pentapeptides. PMID- 30299094 TI - Computational Strategy for Bound State Structure Prediction in Structure-Based Virtual Screening: A Case Study of Protein Tyrosine Phosphatase Receptor Type O Inhibitors. AB - Accurate protein structure in the ligand-bound state is a prerequisite for successful structure-based virtual screening (SBVS). Therefore, applications of SBVS against targets for which only an apo structure is available may be severely limited. To address this constraint, we developed a computational strategy to explore the ligand-bound state of a target protein, by combined use of molecular dynamics simulation, MM/GBSA binding energy calculation, and fragment-centric topographical mapping. Our computational strategy is validated against low molecular weight protein tyrosine phosphatase (LMW-PTP) and then successfully employed in the SBVS against protein tyrosine phosphatase receptor type O (PTPRO), a potential therapeutic target for various diseases. The most potent hit compound GP03 showed an IC50 value of 2.89 MUM for PTPRO and possessed a certain degree of selectivity toward other protein phosphatases. Importantly, we also found that neglecting the ligand energy penalty upon binding partially accounts for the false positive SBVS hits. The preliminary structure-activity relationships of GP03 analogs are also reported. PMID- 30299095 TI - Bottom-Up Assembly of a Highly Efficient Metal-Organic Framework for Cooperative Catalysis. AB - In this study, we demonstrate a bottom-up assembly of a monomeric copper complex and a two-dimensional (2-D) heterometallic metal-organic framework (MOF) from a carboxylate-functionalized tridentate Schiff base ligand and metal ions. The obtained 2-D MOF features a unique bimetallic copper center which is different from its monometallic precursor and acts as an efficient heterogeneous catalyst for the Friedel-Crafts reaction and Henry reaction. The MOF catalyst shows a remarkably superior activity compared to its homogeneous counterparts in a wide range of substrates. It is presumably ascribed to the dual activation of the substrates by the active bimetallic copper center confined in the MOF network, which is supported by the significant changes in catalytic activity at low catalyst/substrates ratios when using the 2-D MOF and its precursor as catalysts, respectively. Moreover, the MOF catalyst also shows an excellent stability and recyclability. Our work, therefore, provides a stepwise strategy to design a heterogeneous cooperative catalyst, by taking advantage of the modulated structure of MOF and tunable functionality of the tridentate Schiff base, with high performance in a variety of organic synthesis. PMID- 30299096 TI - Spatial Distribution of Collections Yielding Marine Natural Products. AB - The societal benefits of coral reef ecosystems include shoreline protection, habitat provision for reef fish, tourism, and recreation. Rarely considered in valuation of reefs is the considerable contribution of marine natural products (MNPs) to both human health and the economy. To better understand the relation of MNP discovery with the characteristics and condition of coral reef ecosystems, we initiated a study to track the collection location and taxonomic identity of organisms that have provided pharmacological products. We reviewed collection information and associated data from 298 pharmacological products originating from marine biota during the past 47 years. The products were developed from 232 different marine species representing 15 phyla, and the 1296 collections of these specimens occurred across 69 countries and seven continents. Our evaluation of the collection data was hampered by sundry observational and reporting issues, including imprecise location descriptions and omission of collection dates. Nonetheless, the study provides an important synopsis and appraisal of years of study and exploration by the marine natural product community. Understanding and quantifying the benefits of MNP discovery will depend upon improved reporting of collections, including accurate taxonomic identification, collection dates, and locations. PMID- 30299097 TI - Charge Transport in [Li(tetraglyme)][bis(trifluoromethane) sulfonimide] Solvate Ionic Liquids: Insight from Molecular Dynamics Simulations. AB - Molecular dynamics simulations using fully atomistic polarizable force field have been performed on solvate ionic liquids (SILs), comprised of tetraglyme (G4) solvent molecules, Li+ cations, and bis(trifluoromethane) sulfonimide (TFSI) anions, [Li(G4)][TFSI]. The SILs with equimolar salt:G4 composition were investigated in the 303-373 K temperature range, whereas several systems with lower salt concentrations were investigated at 373 K. The simulations using polarizable force field demonstrate very good consistency of structural and dynamic properties with experimental data. The ability to accurately sample the ion transport mechanisms is particularly encouraging, taking into account that previous simulations employing nonpolarizable models had challenges in sampling dynamics in these systems. Here, we correlate Li+ ion local environment and glyme conformations with dynamic characteristics, such as residence time of species around Li+, self-diffusion coefficients, transference number, and conductivity. The analysis of contributions to Li+ mobility due to changing its local environment (i.e., moving from one glyme/anion to another) and from translational motion of Li+ with its' coordination environment showed significant dominance of the latter. The contributions of cross-ion dynamic correlations to the total conductivity have been quantified, showing strongly positive contribution from the cation-anion anticorrelation. Despite the high degree of Li-TFSI dissociation and positive contribution of the cation-anion anticorrelated motion to conductivity, the Li+ transference numbers for equimolar SILs are very low under the anion blocking conditions. PMID- 30299098 TI - Ground State Nuclear Magnetic Resonance Chemical Shifts Predict Charge-Separated Excited State Lifetimes. AB - Dichalcogenolene platinum(II) diimine complexes, (LE,E')Pt(bpy), are characterized by charge-separated dichalcogenolene donor (LE,E') -> diimine acceptor (bpy) ligand-to-ligand charge transfer (LL'CT) excited states that lead to their interesting photophysics and potential use in solar energy conversion applications. Despite the intense interest in these complexes, the chalcogen dependence on the lifetime of the triplet LL'CT excited state remains unexplained. Three new (LE,E')Pt(bpy) complexes with mixed chalcogen donors exhibit decay rates that are dominated by a spin-orbit mediated nonradiative pathway, the magnitude of which is proportional to the anisotropic covalency provided by the mixed-chalcogen donor ligand environment. This anisotropic covalency is dramatically revealed in the 13C NMR chemical shifts of the donor carbons that bear the chalcogens and is further probed by S K-edge XAS. Remarkably, the NMR chemical shift differences also correlate with the spin-orbit matrix element that connects the triplet excited state with the ground state. Consequently, triplet LL'CT excited state lifetimes are proportional to both functions, demonstrating that specific ground state NMR chemical shifts can be used to evaluate spin-orbit coupling contributions to excited state lifetimes.

AB - A highly efficient method of visible light mediated Ni(II)-catalyzed photoredox N arylation of Cbz-amines/Boc-amines with aryl electrophiles at room temperature is reported. The methodology provides a common access to a wide variety of N aromatic and N-heteroaromatic carbamate products that find use in the synthesis of several biologically active molecules and provides a distinct advantage over traditional palladium-catalyzed Buchwald reaction. PMID- 30299100 TI - Volatility of Amorphous Solid Water. AB - Amorphous solid water is probably the most abundant form of solid water in the universe. Its saturation vapor pressure and thermodynamic properties, however, are not well known. We have investigated the saturation vapor pressure over vapor deposited amorphous ice at temperatures between 133 and 147 K using a novel experimental method. The new method determines the absolute vapor pressures and the sublimation rates by measuring the mass growth rates of ice-covered nanoparticles under supersaturated water vapor conditions. We find that the vapor pressure of amorphous solid water is up to a factor of 3 higher than that predicted by current parameterizations, which are based in part on calorimetric measurements. We demonstrate that the calorimetric measurements can be reconciled with our data by acknowledging the formation of nanocrystalline ice as an intermediate ice phase during the crystallization of amorphous ice. As a result, we propose a new value for the enthalpy of crystallization of amorphous solid water of Delta H = 2312 +/- 227 J/mol, which is about 1000 J/mol higher than the current consensus. Our results shine a new light on the abundance of water ice clouds on Mars and mesospheric clouds on Earth and may alter our understanding of ice formation in the stratosphere. PMID- 30299101 TI - Accurate Predictions of Electron Binding Energies of Dipole-Bound Anions via Quantum Monte Carlo Methods. AB - Neutral molecules with sufficiently large dipole moments can bind electrons in diffuse nonvalence orbitals with most of their charge density far from the nuclei, forming so-called dipole-bound anions. Because long-range correlation effects play an important role in the binding of an excess electron and overall binding energies are often only on the order of 10s-100s of wave numbers, predictively modeling dipole-bound anions remains a challenge. Here, we demonstrate that quantum Monte Carlo methods can accurately characterize molecular dipole-bound anions with near-threshold dipole moments. We also show that correlated sampling Auxiliary Field Quantum Monte Carlo is particularly well suited for resolving the fine energy differences between the neutral and anionic species. These results shed light on the fundamental limitations of quantum Monte Carlo methods and pave the way toward using them for the study of weakly bound species that are too large to model using traditional electron structure methods. PMID- 30299102 TI - Electron Paramagnetic Resonance and Small-Angle X-ray Scattering Characterization of Solid Lipid Nanoparticles and Nanostructured Lipid Carriers for Dibucaine Encapsulation. AB - Dibucaine (DBC) is one of the most potent long-acting local anesthetics, but it also has significant toxic side effects and low water solubility. Solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) have been proposed as drug-delivery systems to increase the bioavailability of local anesthetics. The purpose of the present study was to characterize SLNs and NLCs composed of cetyl palmitate or myristyl myristate, a mixture of capric and caprylic acids (for NLCs only) plus Pluronic F68 prepared for the encapsulation of DBC. We intended to provide a careful structural characterization of the nanoparticles to identify the relevant architectural parameters that lead to the desirable biological response. Initially, SLNs and NLCs were assessed in terms of their size distribution, morphology, surface charge, and drug loading. Spectroscopic techniques (infrared spectroscopy and electron paramagnetic resonance, EPR) plus small-angle X-ray scattering (SAXS) provided information on the interactions between nanoparticle components and their structural organization. The sizes of nanoparticles were in the 180 nm range with low polydispersity and negative zeta values (-25 to -46 mV). The partition coefficient of DBC between nanoparticles and water at pH 8.2 was very high (>104). EPR (with doxyl-stearate spin labels) data revealed the existence of lamellar arrangements inside the lipid nanoparticles, which was also confirmed by SAXS experiments. Moreover, the addition of DBC increased the molecular packing of both SLN and NLC lipids, indicative of DBC insertion between the lipids, in the milieu assessed by spin labels. Such structural information brings insights into understanding the molecular organization of these versatile drug-delivery systems which have already demonstrated their potential for therapeutic applications in pain control. PMID- 30299103 TI - Mutational Basin-Hopping: Combined Structure and Sequence Optimization for Biomolecules. AB - The study of energy landscapes has led to a good understanding of how and why proteins and nucleic acids adopt their native structure. Through evolution, sequences have adapted until they exhibit a strongly funneled energy landscape, stabilizing the native fold. Design of artificial biomolecules faces the challenge of creating similar stable, minimally frustrated, and functional sequences. Here we present a biminimization approach, mutational basin-hopping, in which we simultaneously use global optimization to optimize the energy and a target function describing a desired property of the system. This optimization of structure and sequence is a generalized basin-hopping method and produces an efficient design process, which can target properties such as binding affinity or solubility. PMID- 30299104 TI - 1,2-Epoxyalkane: Another Precursor for Fabricating Alkoxy Self-Assembled Monolayers on Hydrogen-Terminated Si(111). AB - This work describes the UV alkoxylation of a series of 1,2-epoxyalkanes on the hydrogen-terminated silicon (H-Si) substrate. The formation of alkoxy self assembled monolayers (SAMs) and the nature of bonding at the surface of H-Si were examined using water contact angle goniometer, spectroscopic ellipsometer, Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and atomic force microscopy. UV exposure to 1,2-epoxyalkane mesitylene solution for 60 min formed alkoxy-SAMs onto H-Si with hydrophobic properties. The local molecular environment of the alkyl chains transitioned from a disordered, liquid-like state to an ordered, crystalline-like structure with increasing the chain length. XPS and FTIR indicated that the reaction of H-Si with 1,2 epoxyalkane produced Si-O-C linkages. The Si-H bond homolysis and electron/hole were the plausible mechanistic routes for the grafting of 1,2-epoxyalkanes. PMID- 30299105 TI - Assessment of Th1/Th2 Bias of STING Agonists Coated on Microneedles for Possible Use in Skin Allergen Immunotherapy. AB - Microneedle-based skin allergen-specific immunotherapy (AIT) can benefit from adjuvants that can stimulate a stronger Th1 response against the allergen. We evaluated two stimulator of interferon genes (STING) agonists, namely, cyclic diguanylate monophosphate (c-di-GMP) and cyclic diadenylate monophosphate (c-di AMP), as skin adjuvants using coated microneedles (MNs). For comparison, the approved subcutaneous (SC) hypodermic injection containing alum was used. Ovalbumin (Ova) was used as a model allergen. Ova-specific IgG2a antibody in serum, which is a surrogate marker for Th1 type immune response was significantly higher when STING agonists were used with coated MNs as compared to SC injection of Ova+alum in mice. In contrast, IgG1 antibody, a surrogate marker for Th2 type immune response, was at comparable levels in the MN and SC groups. Restimulation of splenocytes with Ova produced higher levels of Th1 cytokines (IFN-gamma and IL 2) in the STING agonists MN groups as compared to the SC group. In conclusion, delivery of STING agonists into the skin using coated MNs activated the Th1 pathway better than SC- and MN-based delivery of alum. Thus, STING agonists could fulfill the role of adjuvants for skin AIT and even for infectious disease vaccines, where stimulation of the Th1 pathway is of interest.

PMID- 30299106 TI - Mechanism of Goethite Precipitation on Magnetite and Maghemite Nanoparticles Studied by Surface Complexation/Precipitation Modeling. AB - Precipitation of goethite on magnetic nanoparticles (MNPs) has been proposed as an effective means to separate goethite from calcium sulfate in the iron removal process of zinc hydrometallurgy, which allows reuse of the hazardous residues. This study focuses on investigating the underlying mechanisms of goethite precipitation on magnetite and maghemite MNPs, providing insights on Fe(III)aq adsorption and nucleation of goethite on MNPs. A predictive surface complexation/precipitation model of the system was developed based on the results from two different types of experiments: the potentiometric titration of MNPs to calculate proton binding constants ( Ka) of discrete MNP surface functional groups and the corresponding site concentrations; and adsorption of Fe(III)aq onto MNP surfaces to determine metal binding constants ( Kf). The composition of the surface complexes on MNPs was determined by time-of-flight secondary ion mass spectrometry. The results indicated the formation of polynuclear surface complexes. The content of polynuclear surface complexes was found to be significantly higher on maghemite MNPs than on magnetite MNPs. This trend is consistent with our experimental results of a greater goethite precipitation on maghemite than on magnetite. Overall, the formation of Fe(III) polynuclear surface complexes correlates directly to the nucleation and precipitation of goethite on the surfaces of both types of MNPs.

PMID- 30299110 TI - Effects of Occlusion on Periodontal Wound Healing. AB - Trauma from occlusion remains an important concept in dentistry. Traumatic occlusion affects the biological system through a series of events that induces an aseptic inflammatory response and bone resorption. Clinical evidence of these biological events is present in the form of active traumatic lesions or adaptive mechanisms. If these clinical signs are not identified prior to periodontal surgery, failure of the procedure could result due to an exacerbated leukocyte presence and unresolving wound. However, if traumatic occlusion is adjusted, evidence demonstrates that even large inflammatory events such as replantation of an avulsed tooth can be successful. Thus, harmony of occlusal contacts without interference is essential in achieving predictable periodontal/implant bone regeneration.

AB - Over the course of several decades implant dentistry has evolved to include 3 dimensionally (3D) planned and guided surgery. One of the latest innovations is dynamic navigation, which may allow surgeons to place implants with accuracy similar to stereolithographic guides based on 3D, prosthetically directed plans. Benefits of dynamically guided surgery include real-time feedback, a streamlined digital workflow, improved surgical visualization, and adaptability to intraoperative findings. This article discusses the technology and workflow of dynamic navigation and its application for guided implant placement. Additionally, a case completed using this technology is presented. PMID- 30299112 TI - Circumferential Occlusal Access Procedure (COAP): Novel Minimally Invasive Surgical Approach for Treatment of Peri-Implantitis- A Case Series. AB - Treatment of peri-implantitis is typically most successful when a full-thickness surgical flap is elevated to access the contaminated implant surface and the bone loss that has occurred. This approach, however, can be problematic. Primary flap approximation can be challenging after a regenerative procedure, especially with a shallow vestibule, thin mucosa, or minimal zone of keratinized tissue. Incomplete wound closure and soft-tissue dehiscence can lead to membrane and graft exposure. In medicine, minimally invasive techniques have been developed and are being used in an increasing variety of procedures. This article will present the circumferential occlusal access procedure (COAP), a minimally invasive, flapless surgical technique designed to access and detoxify a contaminated implant surface and facilitate bone repair or regeneration while reducing the potential for membrane exposure and recession.

PMID- 30299113 TI - Zygomatic Implants for the Management of Severe Alveolar Atrophy in the Partial or Completely Edentulous Maxilla. AB - Treatment of severely resorbed partially or completely edentulous maxillae can include the utilization of the zygomatic process for immediate implant fixation and stabilization with immediate function. This approach may alleviate the need for significant grafting to enable implant placement in the posterior maxilla and allow implants to be placed into denser, more stable bone. Zygomatic implants, which have been used clinically for the past 20 years in the treatment of the severely resorbed maxilla, allow implant placement to support fixed prosthetics. Their usage can potentially shorten treatment time and reduce costs, as the need to wait for osseous graft maturation is eliminated. Guided surgical approaches are being utilized to maximize placement of the prosthetic platform of these implants.

AB - This study utilizes social-cognitive theory, humble leadership theory, and the behavioral ethics literature to theoretically develop the concept of leader moral humility and its effects on followers. Specifically, we propose a theoretical model wherein leader moral humility and follower implicit theories about morality interact to predict follower moral efficacy, which in turn increases follower prosocial behavior and decreases follower unethical behavior. We furthermore suggest that these effects are strongest when followers hold an incremental implicit theory of morality (i.e., believing that one's morality is malleable). We test and find support for our theoretical model using two multiwave studies with Eastern (Study 1) and Western (Study 2) samples. Furthermore, we demonstrate that leader moral humility predicts follower moral efficacy and moral behaviors above and beyond the effects of ethical leadership and leader general humility.

PMID- 30299116 TI - Assessing suicidality in real time: A psychometric evaluation of self-report items for the assessment of suicidal ideation and its proximal risk factors using ecological momentary assessments. AB - Suicidal ideation is a major risk factor for suicidal behavior and has recently been shown to be fluctuating in studies applying ecological momentary assessments (EMAs). The aims of this study are to introduce a reliable and valid item set for assessing suicidal ideation and relevant proximal risk factors that can be used in future EMA studies within suicidology. Additionally, we provide data on the ability of the items to capture moment-to-moment variability and discuss feasibility aspects of EMA studies on suicidal ideation in a clinical sample. Psychiatric inpatients diagnosed with a depressive disorder (N = 74) rated a set of 28 items measuring suicidal ideation, thwarted belongingness, perceived burdensomeness, depression, anxiety, hopelessness, and positive affect 10 times per day on 6 consecutive days. In addition, these constructs were assessed by self-report questionnaires before and after the EMA period. Intraclass correlations and mean squared successive differences were calculated as indicators of item variability. Reliability was calculated at the prompt (within person) and the person (between-person) level, applying an approach based on multilevel factor analysis. Convergent validity was assessed by correlating the EMA scores with a self-report questionnaire measuring the same constructs. All items demonstrated moment-to-moment-variability and substantial within-person variance. Moreover, all items and scales, except those assessing anxiety, showed satisfying reliability at the prompt and the person level, and correlations indicated convergent validity of the EMA item set. Compliance with the EMAs was excellent (89.7%). Researchers are encouraged to apply this useful tool in future EMA studies in the field of suicidology.

AB - Factor rotation is conducted to aid interpretation in exploratory factor analysis (EFA). Target rotation allows researchers to directly examine the match between the rotated factor loading matrix and their expected factor loading pattern. In some EFA applications, however, researchers have expectations on both the factor loading pattern and the factor correlation pattern. We propose to extend target rotation such that target values can be specified for both factor loadings and factor correlations. We illustrate extended target rotation with a memory study and a personality study with the multitrait-multimethod design. We also explore the statistical properties of extended target rotation using simulated data. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30299118 TI - True virtue, self-presentation, or both?: A behavioral test of impression management and overclaiming. AB - Measures of self-favoring response biases such as impression management (IM) scales or the overclaiming technique (OCT) have been developed to detect distorted self-reports. However, the validity of these approaches has been questioned. In the present study (N = 461), we further examined both IM (assessed by the respective subscale of the Balanced Inventory of Desirable Responding [BIDR]) and the OCT as measures of self-favoring response biases and their associations with honesty-humility. Specifically, we tested the 2 competing accounts of IM as a measure of true virtues or a measure of overly positive self presentation against each other. Using 2 behavioral paradigms, we corroborated recent findings that higher IM scores are associated with higher trait honesty as well as with more honest behavior. At the same time, individuals with high IM scores also presented themselves overly favorably, as IM accounted for discrepancies between hypothetical and actual (incentivized) behavior in a dictator game. Thereby, the present results provide direct evidence for the notion that the IM subscale of the BIDR confounds trait honesty with response bias and thus measures both. In contrast, overclaiming was unrelated to trait honesty, all observed behaviors, and self-presentation, indicating that the OCT is not a valid measure of self-favoring response bias.

AB - Beck's insight-that beliefs about one's self, future, and environment shape behavior-transformed depression treatment. Yet environment beliefs remain relatively understudied. We introduce a set of environment beliefs-primal world beliefs or primals-that concern the world's overall character (e.g., the world is interesting, the world is dangerous). To create a measure, we systematically identified candidate primals (e.g., analyzing tweets, historical texts, etc.); conducted exploratory factor analysis (N = 930) and two confirmatory factor analyses (N = 524; N = 529); examined sequence effects (N = 219) and concurrent validity (N = 122); and conducted test-retests over 2 weeks (n = 122), 9 months (n = 134), and 19 months (n = 398). The resulting 99-item Primals Inventory (PI 99) measures 26 primals with three overarching beliefs-Safe, Enticing, and Alive (mean alpha = .93)-that typically explain ~55% of the common variance. These beliefs were normally distributed; stable (2 weeks, 9 months, and 19 month test retest results averaged .88, .75, and .77, respectively); strongly correlated with many personality and wellbeing variables (e.g., Safe and optimism, r = .61; Enticing and depression, r = -.52; Alive and meaning, r = .54); and explained more variance in life satisfaction, transcendent experience, trust, and gratitude than the BIG 5 (3%, 3%, 6%, and 12% more variance, respectively). In sum, the PI 99 showed strong psychometric characteristics, primals plausibly shape many personality and wellbeing variables, and a broad research effort examining these relationships is warranted.

AB - Analyzing the reading grade level of online mental health information is an important first step in ensuring that information is largely accessible by the general public, so as not to perpetuate existing health disparities across socioeconomic groups. The present study systematically examined grade-level readability of mental health information related to various psychiatric diagnoses, obtained from 6 highly utilized mental health websites, using a generalized estimating equations approach. Results suggest that, in general, the readability of mental health information is largely well above the 6th-to-8th grade level recommended by several national health organizations, including the CDC and NIH (Kutner, Greenberg, Jin, & Paulsen, 2006; National Institutes of Health, 2001, 2017), with reading-grade-level estimates from the model ranging from 5.62 to 17.9. Further efforts are required to ensure that writers of online health information do not exacerbate existing health disparities by ignoring these guidelines.

AB - OBJECTIVE: To measure community mental health agency staff attitudes about employment for persons with serious mental illness. METHODS: An online survey was developed and sent to 2,218 staff at 4 community mental health centers (CMHC) in 1 New England state. The survey collected quantitative and qualitative data about staff attitudes about employment for persons with serious mental illness. Descriptive statistics and qualitative results are provided. Results from analysis of variance are provided as well, assessing differences in staff views by staff characteristics. RESULTS: A mix of clinical and administrative staff participated in the survey (N = 221). Staff views on the benefits of work, the ability of clients to handle the demands of the worker role, and client motivation to work were mixed. Staff with higher levels of education held significantly more supportive views than those with less education. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: CMHC staff need to consistently convey supportive attitudes about employment to their clients. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30299120 TI - Association between fruit and vegetable intake and symptoms of mental health conditions in Mexican Americans. AB - OBJECTIVE: No studies so far have shown the effect of fruit and vegetable intake on mental disorders in Mexican Americans, for whom mental illness is an important health issue. This study measured the association of fruit and vegetable intake with the symptoms of cognitive impairment, the indication of increased risk of dementia, anxiety, and depression in Mexican Americans. METHOD: Participants were drawn from the Cameron County Hispanic Cohort (N = 3,943), a randomly selected Mexican American cohort in Texas on the United States-Mexico border. Consumption of fruit and vegetables and symptoms of four mental disorders were assessed using reliable and validated instruments. RESULTS: Among 2,702 participants (mean age = 50 years, 34% male) with available data, 213 had cognitive impairment, 61 had the indication of increased risk of dementia, 626 had depression, 196 had anxiety, and 787 (29.13%) had mental disorders (i.e., any symptoms of the above four disorders). Participants who met recommendations of 5 or more servings of fruits and vegetables per day were less likely to have anxiety (OR = 0.22, 95% CI [0.08, 0.65], cognitive impairment (OR = 0.16, 95% CI [0.05, 0.46]), and indication of increased risk of dementia (OR = 0.16, 95% CI [0.03, 0.86]) compared with those who did not meet recommendations, after adjusting for covariates. Every portion increment of total fruit and vegetable intake was significantly associated with the reduced odds of mental disorders by 11% and the odds of cognitive impairment by 32%, with the adjustment of other covariates. No significant associations were found between fruit and vegetable intake and depression. CONCLUSION: Fruit and vegetable intake was inversely associated with symptoms of cognitive impairment, the indication of increased risk of dementia, and anxiety in Mexican Americans. Improving consumption of fruit and vegetables may be a convenient target for mental disorder-symptoms prevention and control among Mexican Americans, independent of other factors.

AB - There are approximately 12 million single parent-headed families in the United States (U.S.), 80% of which are headed by single mothers (United States Census Bureau, 2017). Research suggests that single mothers experience more vocational difficulties than married or partnered mothers (Weitoft, Haglund, & Rosen, 2000), especially working single mothers. This study explored the work experiences of racial minority working single mothers at lower-middle income level using a consensual qualitative research method (Hill et al., 2005). Six primary domains emerged from the data: (a) job/education decision-making, (b) challenges, (c) characteristics of self, (d) resources, (e) coping, and (f) suggestions. We present the practical implications of the study to increase vocational mobility, inform practitioners, and promote greater overall wellness for this marginalized group at various system levels. Suggestions for future research with racial minority working single mothers and limitations of the current study are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30299124 TI - Secrets in psychotherapy: For better or worse? AB - We investigated how concealment and disclosure of secrets, two related but distinct processes, unfolded over the course of open-ended therapy for 39 clients and 9 therapists, using hierarchical linear modeling to identify longitudinal patterns and investigate relationships with working alliance and session quality. Results indicated that over the course of therapy, 85% of clients disclosed at least one secret and 41% concealed at least one secret, with 18% of sessions including a disclosure and 4% of sessions including concealment. Over time, clients were less likely to disclose secrets, and the secrets they chose to conceal were rated as less significant. Clients rated the working alliance lower after sessions when they disclosed secrets versus when they did not disclose, although the working alliance was not rated as poorly when the disclosed secrets were viewed as significant. Clients rated session quality higher after sessions when they disclosed secrets versus when they did not disclose, particularly when they disclosed preoccupying secrets. Clients tended to feel neutral or positive about their disclosures. Implications for practice and research are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30299125 TI - Can auditory objects be subitized? AB - In vision, humans have the ability to mentally "tag" approximately 4 objects, allowing us to monitor, attend, and interact with them. As a consequence, we can rapidly and accurately enumerate up to 4 objects-a process known as subitizing. Here, we investigate whether a similar ability exists for tagging auditory stimuli and find that only 2 or 3 auditory stimuli can be enumerated with high accuracy. We assess whether this high accuracy indicates the existence of an auditory subitizing mechanism, and if it is influenced by factors known to influence visual subitizing. On the basis of accuracy, Experiments 1 and 2 reveal a potential auditory subitizing mechanism only when stimuli are spatially separated, as is the case for visual subitizing. Experiment 3 failed to show any evidence of auditory subitizing when objects were separated in time, rather than space. All three experiments provide only limited evidence for an age-related decline in auditory enumeration of small numbers of objects. This suggests that poor auditory tagging does not contribute significantly to older adults' difficulties in multitalker conversations. We hypothesize that although auditory subitizing might occur, it is restricted to approximately 2 spatially separated objects due to the difficulty of parsing the auditory scene into its constituent parts.

AB - The stop-signal task (SST) is assumed to reliably measure response inhibition; specifically, in this task participants sometimes have to withhold a response according to the onset of a sudden cue. The response-stopping process is estimated by a stochastic model that delivers the stop-signal reaction time (SSRT; Verbruggen & Logan, 2009), that is, the latency to inhibit prepotent responses. The right dorsolateral prefrontal cortex (rDLPFC) plays a key role in goal directed cognitive control in general and particularly an increased activation has been associated with better SST performance (that is with shorter SSRT). We stimulated the rDLPFC in a prepost design via transcranial DC stimulation (tDCS). A 9 cm2 anode was always positioned over the rDLPFC while the 35 cm2 cathode was placed over the left deltoid. We contrasted an anodal stimulation condition (that is assumed to enhance neural processing) with sham stimulation and expected an increase in inhibitory functions after anodal tDCS, as evidenced by a decrease in SSRT. In a sample of N = 56 healthy adults, we found a significant Time * tDCS-Condition interaction in the expected direction. Control analysis confirmed that the statistically significant decrease in SSRT after anodal tDCS was not due to generally faster reaction times. These results confirm the role of the rDLPFC for cognitive inhibition processes and further suggest that inhibition is not a fixed resource but depends on the current state of the PFC.

AB - OBJECTIVES: The present study investigates the association between skin color and academic achievement in young Latino students. METHOD: Data were drawn from a longitudinal study of the early development of Latino children that took place in 24 public elementary schools in New York City. Students included in the present analyses (N = 750) were 4 and 5 years old when they were enrolled (baseline) and were followed through the end of first grade. Structural equation models and bootstrapping mediation tests were conducted to examine the effects of skin color on academic achievement at the end of first grade, partially mediated by academic and social emotional domains of school readiness in prekindergarten or kindergarten. This study considered the intersectionality of ethnicity and gender in the models. RESULTS: The findings showed that for Dominican-origin boys, being "collectively black" was indirectly associated with lower academic achievement in first grade, mediated by lower teacher-rated adaptive behavior in prekindergarten or kindergarten. CONCLUSIONS: Discussion focuses on the need for educational policies and practices to be conscious of phenotypicality bias. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30299128 TI - Focusing on what matters: Restructuring the presentation of Bayesian reasoning problems. AB - We propose that a mismatch in problem presentation and question structures may promote errors on Bayesian reasoning problems. In this task, people determine the likelihood that a positive test actually indicates the presence of a condition. Research has shown that people routinely fail to correctly identify this positive predictive value (PPV). We point out that the typical problem structure is likely to confuse reasoners by focusing on the incorrect reference class for answering this diagnostic question; instead, providing the anchor needed to address the diagnostic question about sensitivity (SEN). Results of two experiments are described in which participants answer diagnostic questions using problems presented with congruent or incongruent reference classes. Aligning reference classes eases both representational and computational difficulties, increasing the proportion who were consistently accurate to an unprecedented 93% on PPV questions, and 69% on SEN questions. Analysis of response components from incongruent problems indicated that many errors reflect difficulties in identifying and applying appropriate values from the problem, which are prerequisite processes that contribute to computational errors. We conclude with a discussion of the need, especially in applied settings and on initial exposure, to adopt problem presentations to guide, rather than confuse, the organization and use of diagnostic information.

AB - Interruption interference refers to significant performance decreases that follow task interruption. Evidence has suggested that practicing interruption resumption reduces interruption interference as measured by the time required to resume the interrupted task. However, evidence has also indicated that interruption practice only improves resumption for the practiced pair of primary and interrupting tasks. If this is true, then there is little applied benefit in interruption training, because the training would be unlikely to transfer beyond the training environment. In the current studies, a transfer paradigm was utilized to determine whether interruption resumption skill practiced within a task-pair transfers to a novel task-pair. The results of Experiments 1A and 1B provide evidence that interruption resumption skill transfers to another primary task when the interrupting task is either held constant or varies. Experiment 2 manipulated the primary tasks to minimize the ability to reconstruct the next step in problem solving. When minimizing reconstruction, resumption skill that transfers is likely the ability to successfully retrieve the next planned action that was suspended when interrupted. The results support the conclusion that resumption skill does transfer and, therefore, opens up additional research avenues with applications to minimizing interruption interference.

AB - Attentional refreshing allows the maintenance of information in working memory and has received growing interest in recent years. However, it is still ill defined and several proposals have been put forward to account for its functioning. Among them, some proposals suggest that refreshing relies on the retrieval of knowledge from semantic long-term memory. To examine such a proposal, the present study examined the impact on refreshing of two effects known to affect the retrieval from semantic long-term memory: word frequency and lexicality. In working memory span tasks, participants had to maintain memoranda varying in either frequency, or lexicality while performing concurrent tasks. By examining recall performance in complex span tasks and response times for the concurrent task in Brown-Peterson tasks, the present study provided evidence that long-term memory effects (a) affected recall without interacting with manipulation of refreshing and (b) did not affect refreshing speed. These findings challenge the idea that refreshing acts through the retrieval of knowledge from semantic long-term memory. Different WM models are discussed to account for these findings.

PMID- 30299131 TI - Properties of familiar face representations: Only contrast positive faces contain all information necessary for efficient recognition. AB - It is difficult to recognize the identity of a face presented in negative contrast. This difficulty, however, is substantially reduced when only the eye region is contrast positive in an otherwise negative face image, and recognition of these so-called contrast chimeras approaches performance with full positive faces. This apparently similar accuracy has led researchers to suggest that familiar face representations are built around the eye region. The present study used the N250r, an event-related brain potential correlate of repetition priming, to examine whether chimera recognition is similarly efficient as positive face recognition. In a series of 3 experiments, we found a clear N250r for positive but reduced or even absent repetition effects for negative and chimera faces. This finding held true independent of whether the same basic pictures of familiar faces were used as prime and target stimuli (Experiment 1) or not (Experiments 2 and 3). Similar results were also obtained independent of whether positive, negative or chimera primes preceded full positive targets (Experiments 1 and 2) or targets in the same respective contrast format (Experiment 3). These results indicate that only positive faces contain all information necessary for optimal face recognition and that even though contrast chimeras are recognized highly accurately, the underlying processes work less efficiently as compared with normal face recognition. We conclude that familiar face representations are not built around the eyes but comprise detailed information from other regions of the face.

AB - The present study explored the heterogeneity of military service members' psychological and relational functioning using a sample of 7,866 soldiers in committed romantic relationships from the Army Study to Assess Risk and Resilience in Service members (Army STARRS). A latent profile analysis was conducted to identify and predict unique clusters of soldiers' relative psychological (i.e., posttraumatic stress disorder, depression, and anxiety symptom severity) and relational (i.e., relationship happiness, how often their relationship was going well, how often they confided in their partner, how often they considered or discussed ending their relationship, relational insecurity, and relational turbulence) functioning. Results revealed 4 distinct classes of comparative psychological and relational health: hardy soldiers and healthy relaters (70.2%), stressed soldiers but healthy relaters (13.1%), hardy soldiers but strained relaters (12.7%), and stressed soldiers and strained relaters (4.0%). Class descriptions, as well as implications for theory and clinical practice are reviewed. Notably, 7 out of 10 soldiers in this nationally representative sample reported little to no psychological or relational distress. These findings invite more adaptive narratives of service member resilience and a more nuanced conceptualization of gradations in psychological and relational functioning.

AB - Dyadic interactions may be affected by the mental health of either partner; however, both partners' symptoms are typically not considered simultaneously in observational studies of parent-child relationships. Using the actor-partner interdependence model (APIM), we examine how depression and posttraumatic stress disorder (PTSD) symptoms in mothers and adolescent daughters predict their own and each other's relational behaviors (warmth, hostility, communication) during interactions, and whether partners' relational behaviors predict changes in symptoms 1 month later. Participants include 150 mother (mean age = 41.6) and daughter (mean age = 15.1) dyads from diverse (57% Latina; 23% Black, 20% White), low-income families. Mothers and daughters reported on their symptoms and participated in a videotaped interaction task. A subset completed a follow-up interview 1 month later. For both depression and PTSD, mothers' and daughters' symptoms predicted their own relational behaviors (actor effects). In contrast, partner effects varied by symptom type and family role. Adolescents' depressive symptoms predicted how their mothers acted toward them, beyond maternal symptoms (an additive partner effect); the converse was not true. Mother and daughter PTSD symptoms interactively predicted daughters' relational behaviors (an Actor * Partner interaction), with buffering or exacerbating effects based on dyad symptom similarity. PTSD symptoms had unique effects beyond depression. In longitudinal analysis, mothers' relational behaviors predicted changes in adolescents' depressive symptoms, but adolescent behaviors were unrelated to subsequent maternal symptoms. Findings suggest that depression and PTSD symptoms may affect family relationships differently, and highlight the importance of considering both members' symptoms during interactions. Implications for dyadic interventions are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30299134 TI - Positive parental engagement: Investigating the role of the mother-father relationship. AB - Promoting positive parental engagement (e.g., reading to the child, practicing nursery rhymes with the child, playing with the child) is beneficial for children. Previous research has largely been limited to only maternal reports and relatively affluent families. The current study longitudinally investigated spillover between positive experiences in the mother-father relationship and positive parental engagement using an ethnically and economically diverse sample of parents. Using data from the Fragile Families and Child Wellbeing Study (N = 3,780 mother-father dyads)-and guided by family systems theory-we tested a series of path analysis models. Positive relationship experiences predicted positive parental engagement over time (from child's birth-5 years of age) for both mothers and fathers. Furthermore, strength of associations between positive relationship experiences and positive parental engagement largely did not differ based on family structure, poverty, or race. These findings highlight the importance of investigating the mother-father relationship using a family systems framework to better understand positive parental engagement.

PMID- 30299135 TI - Associations between father involvement and father-child attachment security: Variations based on timing and type of involvement. AB - This study examined associations between father involvement and father-child attachment security, and whether those associations differed as a function of timing (workday and nonworkday) and/or type (accessibility, caregiving, and play) of involvement. Eighty father-child dyads participated when children were approximately 3 years old. Fathers completed a time diary interview assessing the various forms of involvement, and attachment was assessed using the Attachment Q Set (Waters, 1995) following 90 min of father-child observation in the home. On nonworkdays, father involvement in play predicted greater attachment security and involvement in caregiving was marginally associated with greater attachment security. On workdays, father involvement in caregiving was related to greater attachment security, whereas father involvement in play was related to less attachment security. Results were independent of observed paternal sensitivity and relevant demographic covariates. Findings highlight the differential impact of father involvement for the father-child attachment relationship depending on when involvement occurs and what types of activities fathers engage in.

AB - OBJECTIVE: The aim of this study was twofold: (a) to explore patterns of discrimination in relation to broad-basis categories of disability and (b) to investigate patterns of discrimination between allegations derived from charging parties with sensory impairments versus those with nonsensory impairments. Basis categories included physical, behavioral, neurological, and sensory impairments. RESEARCH METHOD: Database mining, descriptive analysis, and Pearson's chi-square analyses were utilized to compare broad-basis categories. RESULTS: In general, regardless of disability type, individuals experience the highest frequency and proportion of workplace discrimination in the areas of termination and reasonable accommodations. However, there are significant differences in the workplace discrimination experiences of the four broader groups. CONCLUSIONS: Noteworthy differences exist regarding the experience of workplace discrimination among basis categories of disability, especially with respect to sensory impairment.

AB - OBJECTIVE: Much is known about the associations between negative factors and adjustment to chronic pain. However, less is known about how positive factors (e.g., positive affect [PA], resilience) function in relation to disability and mood in individuals with multiple sclerosis (MS). To better understand how positive factors contribute to function we sought to determine if (a) PA and/or trait resilience moderate the associations between pain intensity and function (pain interference, depressive symptoms), and (b) trait resilience concurrently mediates the association between PA and function in a sample of individuals with MS. METHOD: There were 455 adults with MS who provided data via an ongoing survey. RESULTS: Controlling for negative affect, demographic, and disease related variables, cross-sectional path analysis revealed the following: PA and trait resilience did not moderate the associations between pain intensity and pain interference (betaPA = 0.01, p = .86; betaRESILIENCE = 0.04, p = .33), and pain intensity and depression (betaPA = 0.01, p = .79; betaRESILIENCE = -0.02, p = .60). However, trait resilience significantly mediated the associations between PA and both criterion variables (abINTERFERENCE = -0.03, p = .03; abDEPRESSION = 0.13, p < .001). CONCLUSIONS: The findings provide preliminary support for the conclusion that PA is indirectly related to pain interference and depression via resilience, rather than serves as a protective function. The findings are consistent with theoretical models suggesting that increases in PA build personal resources. Research examining the potential benefits of increasing PA and resilience to improve pain outcomes in individuals with MS is warranted. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30299138 TI - Anxiety, depression, and function in individuals with chronic physical conditions: A longitudinal analysis. AB - OBJECTIVE: This longitudinal study examined the unique relationship between anxiety, symptoms (pain intensity, sleep disturbance, fatigue severity), and function domains (self-reported cognitive function, physical function, satisfaction with social roles) in individuals with chronic physical conditions, independent of depressive symptoms. METHOD: Three surveys were mailed on an approximately yearly basis to community-dwelling adults with one of four chronic physical conditions (spinal cord injury, multiple sclerosis, muscular dystrophy, postpoliomyelitis syndrome). The first survey was completed by 1594 individuals (T1). Of these, 1380 completed the second survey (T2), and 1272 completed the third survey (T3). RESULTS: Mixed growth curve models evidenced significant concurrent and longitudinal associations between anxiety and each symptom and function domain, independent of depression severity. The largest unique association found was between anxiety and self-reported cognitive function; inclusion of the measure of anxiety in the model improved model fit substantially over depression alone, chi2[2] = 104.40, p < .001. Both anxiety and depression exhibited similar effect sizes in their unique relationships with each symptom and function domain measure. However, depression was more strongly associated with satisfaction with social roles and physical function than was anxiety. CONCLUSIONS: The findings showed that anxiety assessed at one point in time demonstrated significant and unique associations with concurrent and subsequent symptom and function domains. Given that anxiety has been inadequately studied (and perhaps evaluated and treated) in rehabilitation populations, the current findings suggest that researchers and clinicians should broaden their scope when assessing and treating psychological distress to incorporate anxiety and related disorders.

PMID- 30299139 TI - Psychological difficulties and parental well-being in children with musculoskeletal problems in the 2011/2012 National Survey of Children's Health. AB - OBJECTIVE: This study compared children with and without current musculoskeletal (MSK) problems on key indices of child psychological adjustment and parental well being. RESEARCH METHOD: Prevalence estimates of psychological problems were compared for children ages 2-17 years with and without current MSK problems in the 2011/2012 National Survey of Children's Health. Multivariate logistic regression analyses examined the effects of MSK problem severity on the risk of psychological concerns. RESULTS: Population level differences in prevalence estimates were observed in psychological difficulties. Children with MSK problems were disproportionally affected by anxiety problems, depression, behavioral/conduct problems, and ADHD compared to children without MSK problems. Compared to children with mild MSK problems, children with severe MSK problems were 2.74 times more likely to have anxiety problems (95% CI [1.35, 2.86], p < .05). No other significant differences were found among children with mild, moderate, or severe MSK problems. Regarding parental well-being, compared to children without MSK problems, children with MSK problems were more likely to have mothers and fathers who often experience parenting stress/aggravation and have poor physical and mental health. CONCLUSIONS: Children with MSK problems are vulnerable to psychological difficulties that can affect their learning, development, and quality of life. Psychological screening and ensuring that these children receive effective mental health treatments should be a priority in pediatric health care settings. Consideration of parental physical and mental health is recommended in the assessment and treatment of children with MSK problems. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30299140 TI - Sex/gender disparities in health outcomes of individuals with long-term disabling conditions. AB - BACKGROUND: Women with disabling conditions experience health disparities relative to nondisabled women, but few studies have compared women and men with disabling conditions. OBJECTIVES: To investigate gender differences in physical functioning and emotional health among individuals with long-term disabling conditions, that is, neuromuscular disease, multiple sclerosis, postpolio syndrome, or spinal cord injury. METHOD: From a mailed survey of 1,862 adults with long-term disabling conditions, we used the 12-item Patient-Reported Outcomes Measurement Information System (PROMIS) physical functioning to assess physical limitations in activities and Patient Health Questionnaire-9 (PHQ-9) for emotional health and severity of secondary conditions (rated 0-10). Least square means models were used to estimate marginal mean PHQ-9 scores and severity of secondary conditions by age and sex adjusted for diagnosis. Generalized linear models were performed to determine the association between sex/gender and PROMIS physical function t score, controlling for age and diagnostic group with potential Age * Sex interaction. RESULTS: Women reported more fatigue than men (5.48 +/- .08 vs. 5.13 +/- .11, p = .01) and more pain (3.99 +/- .08 vs. 3.67 +/- .11, p = .03). Women aged 45-54 had higher average PHQ-9 scores than men aged 45 54 (M = 8.05, SE = .33 vs. M = 6.35, SE = .42, p < .007) adjusted for diagnosis. Younger women had higher physical functioning than younger men while older women had lower physical functioning than older men adjusted for diagnostic group (p = .0003 for the interaction term). CONCLUSION: Middle-aged and older women with long-term disabling conditions experience considerable health disparities in physical functioning and emotional health compared with middle-aged and older men with similar conditions.

AB - Long-standing social problems such as poor achievement, personal and intergroup conflict, bad health, and unhappiness can seem like permanent features of the social landscape. We describe an approach to such problems rooted in basic theory and research in social psychology. This approach emphasizes subjective meaning making-working hypotheses people draw about themselves, other people, and social situations; how deleterious meanings can arise from social and cultural contexts; how interventions to change meanings can help people flourish; and how initial change can become embedded to alter the course of people's lives. We further describe how this approach relates to and complements other prominent approaches to social reform, which emphasize not subjective meaning-making but objective change in situations or in the habits and skills of individuals. In so doing, we provide a comprehensive theoretical review and organization of a psychologically informed approach to social problems, one that encompasses a wide-range of interventions and applies to diverse problem areas.

AB - Theories of functioning in the medial prefrontal cortex are distinct across appetitively and aversively motivated procedures. In the appetitive domain, it is argued that the medial prefrontal cortex is important for producing adaptive behavior when circumstances change. This view advocates a role for this region in using higher-order information to bias performance appropriate to that circumstance. Conversely, literature born out of aversive studies has led to the theory that the prelimbic region of the medial prefrontal cortex is necessary for the expression of conditioned fear, whereas the infralimbic region is necessary for a decrease in responding following extinction. Here, the argument is that these regions are primed to increase or decrease fear responses and that this tendency is gated by subcortical inputs. However, we believe the data from aversive studies can be explained by a supraordinate role for the medial prefrontal cortex in behavioral flexibility, in line with the appetitive literature. Using a dichotomy between the voluntary control of behavior and the execution of well-trained responses, we attempt to reconcile these theories. We argue that the prelimbic region exerts voluntary control over behavior via top down modulation of stimulus-response pathways according to task demands, contextual cues, and how well a stimulus predicts an outcome. Conversely, the infralimbic region promotes responding based on the strength of stimulus-response pathways determined by experience with reinforced contingencies. This system resolves the tension between executing voluntary actions sensitive to recent changes in contingencies, and responses that reflect the animal's experience across the long run.

AB - Regenwetter and Robinson (2017) discuss a challenging construct-behavior gap in psychological research. It can emerge when testing hypotheses that pertain to a theoretical construct (e.g., preferences) on the basis of observed behavior (e.g., actual choices). The problem is that the different heuristic methods that are sometimes used to link overt choices to covert preferences may ignore heterogeneity between and within individuals, rendering inferences drawn from choices to preferences invalid. Regenwetter and Robinson's remedy is to make heterogeneity an explicit part of the theory. They illustrate the problem and a remedy to it with the description-experience gap (D-E gap), the systematic gap in choices based on described versus 'experienced' probabilities. We welcome their sophisticated reanalysis of some early data sets, which, by taking heterogeneity into account, finds strong evidence for a D-E gap in probability weighting. Yet we see three issues with the remedy, which we likewise highlight using the D-E gap. First, the D-E gap cannot be reduced solely to probability weighting but rather unfolds across several different psychological constructs suggesting that part of the construct-behavior gap may stem from trying to reduce multidimensional behavior to a single construct. Second, the authors' modeling of heterogeneity leaves aside the heterogeneity of people's sampled experience in decisions from experience, which highlights the importance of also considering the potential causes of heterogeneity. Third, we identify potential sources of heterogeneity in choice behavior that go beyond probabilistic responses and preferences and advocate for a pluralistic approach to modeling it. Last but not least, we emphasize that, notwithstanding the importance of rigor and logical coherence in scientific theories, simplifications and (false) generalizations are indispensable in the pursuit of scientific knowledge.

AB - In psychological experiments, behavioral speed varies across trials, and this variation is often associated with corresponding fluctuations in cortical activity. Little is known about such cortical variations in semantic priming tasks where target words are matched with preceding sensory object cues. Here, two visually presented target words ("pear" and "lilac") were repeatedly cued by corresponding odors or pictures, and the participants were to indicate matching or nonmatching combinations. Data were split in behaviorally "fast" versus "slow" trials. We hypothesized that slow trials would be associated with higher prestimulus alpha activity and reduced ERP amplitudes, and that response-time differences between odor-cued and picture-cued trials would be especially large in slow behavioral trials. Results confirmed that slow trials showed increased alpha-band activity prior to word target onset, as well as amplitude decreases in the sensory P1 and semantic N400 components. However, no interactions between cue modality and processing speed were observed. Instead, odor-cue integration responses were uniquely delayed on incongruent trials, a novel behavioral effect that was not observed in EEG measures. The results show that semantic integration speed is reflected in cortical activity before and during stimulus processing. Behavioral interactions with cue modality did not correspond to observed cortical activity changes, perhaps because olfactory circuits are not readily observed in scalp-recorded EEG. We conclude that combining behavioral speed variability and cortical EEG measures is useful in understanding the fluctuating nature of cognitive processing sequences.

AB - It is frequently assumed that infants are impaired in contextual memory and consequently, in recovery from extinction, a phenomenon considered to be context dependent. However, the evidence in the field is far from consistent with this interpretation, since several studies have shown context-dependent extinction in infant rats using a variety of procedures and behavioral measures. This discussion has primarily been based on studies using Pavlovian conditioning tasks. Three experiments were conducted to study reinstatement of an extinguished operant response and additionally to evaluate the context dependence of such an effect. Preweanling rats were trained on postnatal days (PDs) 16 and 17 to acquire an appetitive operant response using chocolate milk as reinforcer. At PD18 the operant response was extinguished and at PD19 animals received a reminder in the same (Experiment 1 and 2) or in a different context than the one used during the extinction phase (Experiment 3). Infant rats showed recovery from extinction after a reminder treatment (Experiments 2 and 3). This effect was dependent on the context in which the reminder was delivered (Experiment 3). Our results indicate that infant rats can recover an extinguished operant response by means of a reminder treatment in a context-dependent way, highlighting the importance of the context for modulating learning processes during infancy.

PMID- 30299146 TI - Blockade of dopamine D1 receptors, but not D2 receptors, decreases motivation in a novel effort-discounting paradigm in common marmosets. AB - Effort-based decision-making paradigms have recently been used to measure motivation in healthy subjects and patients with neuropsychiatric disorders. In the present study, we developed a novel effort-discounting paradigm using a touch panel system in common marmosets. Marmosets were trained to choose between a low reward (a piece of cake) requiring low-effort (one touch response) versus high reward (three pieces of cake) requiring one of three different effort levels (one, two, or four touch responses). Because the number of trials per session was kept constant, the selection of the high-reward choice was always the optimal strategy to receive the maximum number of rewards. Marmosets' high-reward rates were reduced as the physical effort requirement was increased, when they were tested using effort discounting in either ascending or descending order of effort intensity. It indicates that marmosets' decisions could be attributable to cost benefit evaluation, but not to their fatigue or satisfaction with the reward during the progression of the paradigm. The high dose of dopamine D1 receptor antagonist SCH-39166 (0.03 mg/kg) reduced the high-reward choice rate, only when more effort was required to obtain the high-reward than the low-reward. On the other hand, the D2 receptor antagonist raclopride (0.01 and 0.03 mg/kg) unexpectedly did not affect the high-reward choice rate, but the high dose did increase omission rate. Our finding suggests that dopamine D1 receptor signaling may play a more important role in effort-based decision making than D2 receptor signaling in marmosets. Our novel behavioral paradigm would be useful in translational research focused on motivational deficits. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30299147 TI - Reversal learning impairments in the maternal immune activation rat model of schizophrenia. AB - One of the cognitive symptoms observed in schizophrenia is decreased flexibility in several tasks, including reversal learning. Reversal learning has previously been tested in rats following maternal immune activation (MIA), a risk factor for schizophrenia, with varying results. Whereas some previous studies have shown that MIA rats are slower to learn a reversal, others have reported more rapid learning compared with controls. Several of these latter studies have, however, used a T-maze task with aversive, negative reinforcement as a motivating factor. Because most human studies use positive reinforcement in reversal tasks, here we tested whether reinforcement valence might be a critical factor. We ran male MIA and control rats in a T-maze reversal procedure that was very similar to previous studies except that positive, appetitive reinforcement was used for motivation. The results showed that MIA animals performed similarly to controls during training, but in contrast to the previous, aversively motivated T-maze studies, slower reversal learning was observed. These results show that MIA animals are impaired in reversal learning under conditions of positive reinforcement, consistent with the effects observed in individuals with schizophrenia.

AB - Limb immobilization paradigms are increasingly used to investigate changes in brain plasticity and support potential rehabilitation techniques that might help counteract motor impairments. Yet, it remains unclear how unilateral arm immobilization may influence the sensorimotor representation and functional output for both arms. Using a randomized crossover design, 14 participants underwent a baseline test, followed by two experimental conditions separated by 1 week: a right (dominant) arm immobilization phase over a period of 8 hr and a no immobilization (or control) phase also lasting 8 hr. Before and after each condition, participants were tested on a hand laterality judgment task to assess changes in sensorimotor representation of the hands, followed by an out-and-back reaching motor task measuring changes in spatiotemporal components of motor actions. Data from the hand laterality judgment task revealed that participants were faster at identifying right-hand pictures after the control phase, but such improvement was not observed after the immobilization phase, with no effect of immobilization for pictures depicting the overused left hand. Results from the reaching motor task revealed that the right-arm movement planning component was altered after immobilization, whereas there was no effect for the overused left arm. Altogether, these findings demonstrate that an 8-hr period of unilateral immobilization affects sensorimotor representation and functions of the corresponding limb, but not of the overused, nonimmobilized hand.

PMID- 30299149 TI - The relationship between on-campus service utilization and common mental health concerns in undergraduate college students. AB - Little research exists into the trends associated with on-campus service utilization for mental health concerns of college students. Rates of broad service utilization exist, but no published study has examined the direct relationship between a range of common mental health symptoms and on-campus service utilization. The aims of the present study are to explore (1) which common mental health concerns are associated with specific on-campus service utilization in undergraduate students and (2) whether endorsement of more mental health concerns will predict a higher number of services utilized. Data were utilized from 3,734 undergraduates at a large (more than 20,000 undergraduates), urban university (Mage = 19.94 years, SD = 0.55 years; female = 66%). Four on campus services (University Counseling Services, University Health Services, The Wellness Resource Center, and Disability Support Services) were regressed onto mental health concerns associated with symptoms of three disorders (anxiety, depression, alcohol use disorder [AUD]) and two mental health risk factors (stressful life events [SLEs], antisocial behaviors [ASBs]). AUD symptoms predicted the most overall and specific service utilization, followed by depression symptoms and SLEs. Anxiety symptoms and ASBs were not significant predictors when combined with other variables. This is the first study to investigate trends specific to on-campus college student service utilization. Findings will be helpful to mental health professionals on similar college campuses by providing insight into programming and outreach initiatives for these or related services.

PMID- 30299150 TI - Psychometric properties of a brief measure of posttraumatic stress disorder related impairment: The Brief Inventory of Psychosocial Functioning. AB - This study validated the Brief Inventory of Psychosocial Functioning (B-IPF), an abridged version of the 80-item Inventory of Psychosocial Functioning (IPF; Bovin et al., 2018). The B-IPF-a 7-item self-report questionnaire that assesses posttraumatic stress disorder (PTSD)-related psychosocial functional impairment was developed for use in settings in which the full IPF would be too time intensive to administer. In this study, we examined the psychometric properties of the B-IPF among a sample of 362 veterans recruited from 2 Veterans Affairs hospitals. The B-IPF demonstrated high internal consistency (Cronbach's alpha = .84) and adequate test-retest reliability (r = .65, p < .001). The B-IPF was strongly correlated with the IPF (r = .71, p < .01) and had higher correlations with measures of mental health impairment and quality of life (all rs > ?.50?; all ps < .001) than with a measure of physical health impairment (i.e., the Physical Component Summary; r = -.34; p < .001), which demonstrated strong construct validity. In addition, the B-IPF displayed strong criterion-related validity, with higher correlations with a PTSD symptom measure, (r = .63, p < .05), and measures of other internalizing disorders (all rs > .44; all ps < .05) and a lower correlation with a measure of an externalizing disorder (r = .14; p < .05). These results indicate that the B-IPF is a reliable and valid instrument for assessing PTSD-related impairment. The strong psychometric properties of the instrument, in addition to its length, make it ideal for settings in which time is a factor. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30299151 TI - Mental health utilization among veterans at risk for suicide: Data from a post deployment clinic. AB - The current study aim was to examine mental health characteristics in a sample of returning OEF/OIF/OND veterans initially enrolling in Department of Veterans Affairs (VA) health care (N = 1,307), with a particular focus on a subgroup considered at risk for suicide (N = 445). Methods included examination of mental health screening measures and clinical interview data from a VA postdeployment clinic. Half of the sample met criteria for a mental health disorder, whereas 10% reported current suicidal or death ideation (e.g., thoughts of being better off dead or hurting oneself in some way) and 6% reported a history of suicide attempt. Sixty-eight percent of the at-risk subgroup accepted a referral for mental health treatment and a promising majority (78%) of those individuals attended their initial specialty mental health visit. At-risk veterans who accepted mental health referral were more likely to report current suicidal/death ideation; they were also more likely to have a diagnosis of a depressive disorder, anxiety disorder, or posttraumatic stress disorder. Factors associated with mental health appointment attendance included older age, being enrolled in college, and more years of military service. Results highlight the importance of early screening and referral to appropriate mental health follow-up. Implications for clinical practice and increasing engagement in VA mental health services among veterans at risk for suicide are discussed.

AB - Studies on socioemotional selectivity theory have found that compared with younger adults, older adults are more likely to (a) prefer to interact with emotionally close social partners and (b) show preferential cognitive processing of positive relative to negative stimuli. To integrate these 2 lines of findings, this study examined attention toward emotional (positive and negative) facial expressions of experimentally manipulated emotionally close versus nonclose targets among younger and older adults. Compared with younger adults, older adults gazed more at facial expressions of emotionally close than nonclose targets, regardless of valence. This age difference occurred to a greater extent among those who endorsed eudaimonic goals more. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30299153 TI - Age-related differences in levels and dynamics of workplace affect. AB - Affective experiences at work are a key contributing factor to long-term job related well-being and effectiveness, yet may systematically change as workers get older. Given the central role of affect in work settings, it is important to obtain a thorough understanding of older workers' strengths and vulnerabilities in affective functioning. This paper's goal was to comprehensively study age differences in mean levels and dynamics of affect (affect stability, occurrence of positive and negative daily work events, and affective reactivity) and to link these with perceptions of global occupational well-being and effectiveness. In three diary studies, employees of different occupational and cultural backgrounds (Hong Kong Chinese managerial employees, German hospital employees, German office workers) reported daily affective work events and affect across multiple workdays. Higher age was associated with more positive and less negative affect (Study 1), more frequent positive daily work events (Study 2 and 3), and lower variability of negative affect (Study 1 and 2). Age was unrelated to frequency of negative work events and positive event reactivity (all studies). There were mixed age differences in negative event reactivity (lower reactivity in Study 1 and on subtypes of affect in Study 2, but higher worry in Study 3). Several of the indicators of affective experience emerged as mediators of positive age differences in work engagement and self-rated task performance. Overall, with one exception, results point at maintenance or improvement of workers' affective functioning with age. Through improved affective functioning, older workers likely contribute to organizational effectiveness. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30299154 TI - Valuing excitement makes people look forward to old age less and dread it more. AB - Previous research has shown that American culture places a premium on excitement, enthusiasm, and other high-arousal positive states (HAP) compared with various East Asian cultures. In two studies, we tested the prediction that valuing HAP would be associated with less positive personal views of old age (i.e., fewer things people looked forward to and more things they dreaded about old age) in samples of European American, Chinese American, and Hong Kong Chinese younger, middle-aged, and older adults. In Study 1 (N = 849), participants rated how much they ideally wanted to feel HAP during a typical week and described their personal views of old age. As predicted, European American middle and older adults valued HAP more than did their Chinese American and Hong Kong Chinese peers, and these differences in ideal HAP were related to less positive personal views of old age. In Study 2 (N = 164), we experimentally manipulated how much individuals valued HAP and then assessed their personal views of old age: Across cultures, participants in the "value HAP" condition had less positive personal views of old age than did those in the control condition. These effects did not emerge for societal views of old age (i.e., what people associated with "someone" old vs. young). Together, these findings suggest that people's personal views of their own old age are due, in part, to how much excitement they ideally want to feel.

AB - A number of studies have investigated the role of coping and social support as protective factors for psychosocial adjustment after amputation. In contrast, few have focused on the role of attachment styles. Therefore, the purpose of this study was to examine the relationship between attachment insecurity, social support, coping strategies and negative emotions, such as anxiety and depression, in adult amputees. Sixty-two amputated adults (71% males, 29% females), recruited from the Prosthetic Centre of the Italian Workers' Compensation Authority, completed the Attachment Style Questionnaire, the Coping Inventory for Stressful Situations, the Multidimensional Scale of Perceived Social Support, the Beck Depression Inventory II and the State-Trait Anxiety Inventory Y. Based on Pearson's correlations results, we conducted a mediation analysis to examine whether the association between attachment insecurity (i.e., attachment anxiety and attachment avoidance) and negative emotion (i.e. depression, state anxiety and trait anxiety) variables was mediated by emotion-oriented coping. Analyses revealed the role of insecure attachment styles in influencing the use of an emotion-oriented coping strategy in particular. The latter mediated the relationship between attachment insecurity, depression and anxiety in adult amputees. PMID- 30299155 TI - The mapping between transformed reaction time costs and models of processing in aging and cognition. AB - Older adults tend to have slower response times (RTs) than younger adults on cognitive tasks. This makes the examination of domain-specific deficits in aging difficult, as differences between conditions in raw RTs (RT costs) typically increase with slower average RTs. Here, we examine the mapping between 2 established approaches to dealing with this confound in the literature. The first is to use transformed RT costs, with the z-score and proportional transforms both being commonly used. The second is to use mathematical models of choice RT behavior, such as the drift-diffusion model (Ratcliff, 1978). We simulated data for younger and older adults from the drift-diffusion model under 4 scenarios: (a) a domain specific deficit, (b) general slowing, (c) strategic slowing, and (d) a slowing of nondecision processes. In each scenario we varied the size of the difference between younger and older adults in the model parameters, and examined corresponding effect sizes and Type I error rates in the raw and transformed RT costs. The z-score transformation provided better control of Type I error rates than the raw or proportional costs, though did not fully control for differences in the general slowing and strategic slowing scenarios. We recommend that RT analyses are ideally supplemented by analyses of error rates where possible, as these may help to identify the presence of confounds. To facilitate this, it would be beneficial to include conditions that elicit below ceiling accuracy in tasks. (PsycINFO Database Record (c) 2018 APA, all rights reserved). PMID- 30299157 TI - Distribution of tumor-infiltrating immune cells in glioblastoma. AB - AIM: Evaluation of features related to infiltrating immune cell level in glioblastoma. METHODS: Tumor-infiltrating lymphocytes (TILs) through H&E staining, and TILs (CD3, CD4, CD8 and CD20) and macrophage (CD68 and CD163) levels through immunohistochemistry were evaluated through digital analysis. RESULTS: CD68 (9.1%), CD163 (2.2%), CD3 (1.6%) and CD8 (1.6%) had the highest density. Higher CD4+ was associated with unmethylated MGMT (p = 0.016). Higher CD8+ was associated with larger tumoral size (p = 0.027). Higher CD163+ was associated with higher age (p = 0.044) and recursive partitioning analysis = 4. Women (p < 0.05), total resection (p < 0.05), MGMT-methylation (p < 0.001), radiotherapy (p < 0.001), chemotherapy (p < 0.001) and lower CD4+ (p < 0.05) were associated with longer overall survival. CONCLUSION: Macrophages are more frequent than TILs. Some subsets are associated with clinical features. PMID- 30299158 TI - High School Athletic Trainer Services for Knee Injuries. AB - CONTEXT: Participation in high school athletics carries a substantial risk of musculoskeletal injury, particularly to the knee. However, limited information is available on the care being provided by athletic trainers (ATs) for athletes with these injuries. DESIGN: Descriptive epidemiology study. SETTING: Data on athletic training facility visits and AT services were collected from 147 high schools in 26 states. PATIENTS OR OTHER PARTICIPANTS: High school student-athletes who participated in 13 boys' sports and 14 girls' sports and sustained a diagnosed knee injury during the 2011-2012 through 2013-2014 academic years. The ATs documented 6797 knee injuries, with 4242 sustained in boys' sports and 2555 sustained in girls' sports. MAIN OUTCOME MEASURE(S): The number of athletic training facility visits and individual AT services as well as the average, median, and interquartile range of athletic training facility visits (per injury) and AT services (per injury) were calculated by sport and for time-loss (TL; participation restricted for >=24 hours) and non-time-loss (NTL; participation restricted for <24 hours) injuries. RESULTS: In total, 28 788 athletic training facility visits were reported, with an overall average of 4 athletic training facility visits per knee injury over the 3-year period. Most athletic training facility visits (72.6%) were associated with NTL injuries, but the majority of AT services (68.6%) were associated with TL injuries. A total of 81 245 AT services were provided for all knee injuries. Therapeutic activities or exercise were the most common type of AT service (52.5%). Overall, an average of 12 AT services were reported per knee injury. Compared with NTL injuries, TL injuries had a larger average number of AT services per injury (34 versus 9; P < .001). CONCLUSIONS: Knee injuries at the high school level are a considerable health care burden. This report demonstrates a high proportion of AT attention to the evaluation and treatment of these injuries. This study confirms the recommended management of knee injuries, with neuromuscular and therapeutic activities being the primary services after knee injury. PMID- 30299160 TI - Vinorelbine cationic liposomes modified with wheat germ agglutinin for inhibiting tumor metastasis in treatment of brain glioma. AB - Glioma is the most common primary malignant brain tumor with a poor prognosis. The application of chemotherapeutic drugs is limited due to the existence of blood-brain barrier and serious side effects. Liposomes have been proven to be a stable and useful drug delivery system for tumors. In this paper, WGA (wheat germ agglutinin) modified vinorelbine cationic liposomes had been successfully constructed for treating glioma. In the liposomes, WGA was modified on the liposomal surface for crossing the blood-brain barrier and increasing the targeting effects, 3-(N-(N', N'-dimethylaminoethane) carbamoyl) cholesterol (DC Chol) was used as cationic material and vinorelbine was encapsulated in the aqueous core of liposomes to inhibit tumor metastasis and kill tumor cells. Studies were performed on C6 cells in vitro and were verified in brain glioma bearing mice in vivo. Results in vitro demonstrated that the targeting liposomes could induce C6 cells apoptosis, promote drugs across the blood-brain barrier, inhibit the metastasis of tumor cells and increase targeting effects to tumor cells. Meanwhile, action mechanism studies showed that the targeting liposomes could down-regulate PI3K, MMP-2, MMP-9 and FAK to inhibit tumor metastasis. Results in vivo exhibited that the targeting liposomes displayed an obvious antitumor efficacy by accumulating selectively in tumor site and exhibited low toxicity to blood system and major organs. Hence, WGA modified vinorelbine cationic liposomes might provide a safe and efficient therapy strategy for glioma. PMID- 30299161 TI - Loss of functional connectivity is an early imaging marker in primary lateral sclerosis. AB - OBJECTIVE: The clinical diagnosis of primary lateral sclerosis can only be made after upper motor neuron symptoms have progressed for several years without developing lower motor neuron signs. The goal of the study was to identify neuroimaging changes that occur early in primary lateral sclerosis, prior to clinical diagnosis. METHODS: MRI scans were obtained on 13 patients with adult onset progressive spasticity for five years or less who were followed longitudinally to confirm a clinical diagnosis of primary lateral sclerosis. Resting state functional MRI, diffusion tensor imaging, and anatomical images were obtained. These "pre-PLS" patients were compared to 18 patients with longstanding, established primary lateral sclerosis and 28 controls. RESULTS: Pre PLS patients had a marked reduction in seed-based resting-state motor network connectivity compared to the controls and patients with longstanding disease. White matter regions with reduced fractional anisotropy were similar in the two patient groups compared to the controls. Patients with longstanding disease had cortical thinning of the precentral gyrus. A slight thinning of the right precentral gyrus was detected in initial pre-PLS patients' scans. Follow-up scans in eight pre-PLS patients 1-2 years later showed increasing motor connectivity, thinning of the precentral gyrus, and no change in diffusion measures of the corticospinal tract or callosal motor region. CONCLUSIONS: Loss of motor functional connectivity is an early imaging marker in primary lateral sclerosis. This differs from literature descriptions of amyotrophic lateral sclerosis, warranting further studies to test whether resting-state functional MRI can differentiate between amyotrophic lateral sclerosis and primary lateral sclerosis at early disease stages.

AB - CONTEXT: Functional performance tests (FPTs) are tools used to assess dynamic muscle strength and power. In contrast to the lower extremity, fewer FPTs are available for the upper extremity. The seated single-arm shot put test has the potential to fill the void in upper extremity FPTs; however, the underlying mechanics have not been examined and, therefore, the validity of bilateral comparisons is unknown. OBJECTIVE: To examine the effects of upper extremity dominance and medicine-ball mass on the underlying mechanics of the seated single arm shot put. DESIGN: Crossover study. SETTING: Biomechanics laboratory. PATIENTS OR OTHER PARTICIPANTS: Fifteen women (age = 23.6 +/- 2.1 years, height = 1.65 +/- .07 m, mass = 68.1 +/- 11.7 kg) and 15 men (age = 24.3 +/- 4.0 years, height = 1.80 +/- 0.06 m, mass = 88.1 +/- 16.4 kg), all healthy and physically active. INTERVENTION(S): Seated single-arm shot-put trials using the dominant and nondominant limbs were completed using three 0.114-m-diameter medicine-ball loads (1 kg, 2 kg, 3 kg). MAIN OUTCOME MEASURE(S): Customized touch-sensitive gloves, synchronized with kinematic data of the hands, signaled ball release, so that release height, release angle, and peak anterior and vertical velocity could be quantified for each trial. In addition, the horizontal range from release to first floor impact was recorded. RESULTS: The dominant-limb horizontal ranges were 7% to 11% greater ( P < .001) than for the nondominant limb for each of the 3 ball masses. No bilateral release-height or -angle differences were revealed ( P >= .063). Release velocities were 7.6% greater for the dominant limb than the nondominant limb ( P = .001). CONCLUSIONS: Our results support the use of the seated single-arm shot put test as a way to compare bilateral upper extremity functional performance. The near-identical release heights and angles between the dominant and nondominant limbs support the interpretation of measured bilateral horizontal-range differences as reflecting underlying strength and power differences.

AB - OBJECTIVE: The palmomental reflex (PMR) is a primitive reflex, which may appear when cortical inhibitory pathways are disrupted by disease. In this study, we examined whether the PMR is associated with corticobulbar involvement in people with ALS (PALS). METHODS: PMR was routinely tested for each patient attending the ALS clinic. Three hundred and eighteen consecutive PALS were included, of whom 271 were PMR positive (PMR+). Clinical evaluation defined the presence of upper motor neuron (UMN) and lower motor neuron (LMN) signs in the bulbar, cervical and lumbosacral segments. RESULTS: The PMR + group had a higher rate of both UMN and LMN bulbar involvement (BI) as well as more UMN upper-limb involvement and UMN involvement of any type, the strongest association being between PMR + and UMN BI. In patients without BI at presentation, UMN BI developed roughly 15 months early in the PMR + group compared to the PMR- group. CONCLUSION: We found that the PMR is strongly associated with UMN signs within the bulbar region and to a lesser extent with upper-limb UMN involvement. We propose the PMR be considered a harbinger of corticobulbar involvement in PALS. PMID- 30299163 TI - Ancient philosophers on mental illness. AB - This article explores how the ancient philosophers from Plato to late antiquity understood mental illness. It outlines when, how and in what kind of contexts the phenomenon of mental illness was recognized in the ancient philosophical texts, how mental illness was understood in terms of the body-mind interaction, and how mental disorders of the medical kind were distinguished from non-medical psychic disturbances. It establishes that, while the philosophers mostly understood mental illness along the lines of ancient medical thinking, their ideas, for example on the nature and location of the soul, informed their theories of mental illness.

AB - In order to investigate the biocatalytic properties of alpha-amylase on a composite cryogel matrix with immobilized metal affinity chromatography, Cu+2 attached poly(2-hydroxyethyl methacrylate) (Cu+2-PHEMA) beads, (2 um size) were synthesized, then composite cryogel column was prepared by composing beads and PHEMA cryogels. After the preparation of Cu+2-PHEMA beads embedded cryogel column (Cu+2-BEC), some experiments were tested. Accordingly, the highest adsorption capacity (676.8 mg/g particles) of cryogels was achieved at acetate buffer of pH 5.0 with initial alpha-amylase concentration of 4 mg/mL. Immobilized enzyme has more stable pH range, between 6 and 7.5 than, the free one. Immobilization also increased the optimal activity from 25 to temperature range of 25-35 degrees C. Vmax and Km of alpha-amylase were detected as 1.149 U/mg protein, and 11.6 * 10-1 mM, respectively. alpha-Amylase was utilized 35 times repeatedly without losing the productivity.

AB - At the turn of the millennium, people with mental disturbance often lived in circumstances of economic marginalization in South Africa. The historical material of one low-income urban area reveals the place of kin relations and reciprocity in enabling negotiation of a more fluid set of responses to mental illness. In this sociocultural context, "stigma" was not an inevitable reaction to mental illness, and a more complex set of social dynamics could mitigate marginalization. Research on how changing informal care practices relate to state based community care continues to be important to inform contemporary health reforms. PMID- 30299166 TI - Risk of preterm birth in primiparous women with exposure to antidepressant medication before pregnancy and/or during pregnancy - impact of body mass index. AB - INTRODUCTION: Preterm birth is a major cause of infant mortality. It is unknown whether body mass index (BMI) influences the risk of preterm birth in women, who prenatally use antidepressants. MATERIALS AND METHODS: The study cohort (N = 6920) consists of all primiparous European born women without previously diagnosed diabetes from the city of Vantaa, Finland, who delivered a singleton child between 2009 and 2015. Data on births, pre-pregnancy BMI and purchases of antidepressants from 12 months before conception until delivery were obtained from Finnish National Registers. RESULTS: Of the primiparous women, 9.9% used antidepressants. The overall prevalence of preterm birth was 5.2%. In women with a pre-pregnancy BMI <18.5 kg/m2, the Odds Ratio (OR) for preterm birth among antidepressant users compared with those who were non-users was 1.91 (95% confidence intervals [CI] 0.40 to 9.15, adjusted for age, smoking, education, use of fertility treatments and number of previous pregnancies) while in women with a pre-pregnancy BMI >=30 kg/m2, the OR was 0.53 (95% CI 0.21-1.36), respectively. DISCUSSION: Primiparous women using antidepressants, who were underweight before conception should be closely monitored and provided tailored care in a maternity clinic to minimize the risk of preterm birth. Key messages In primiparous women, one in ten used antidepressant medications before pregnancy and/or during pregnancy. In primiparous women, the prevalence of preterm birth was 5%. Underweight primiparous women using antidepressants should be closely monitored and provided tailored care in a maternity clinic. PMID- 30299167 TI - Making it work: experience of living with a person who falls due to multiple sclerosis. AB - PURPOSE: The purpose of this study was to describe how everyday life is experienced by next of kin sharing residence with a person who falls due to multiple sclerosis (MS). METHODS: Twenty face-to-face interviews were analysed using a qualitative content analysis. RESULTS: The overall theme "Making it work" represents the next of kin's struggle to make life work. It comprises three themes: "Taking responsibility", "Making adjustments", and "Standing aside for someone else". The two first themes reflect what relatives do to make the situation work, and the last theme represents what they give up. CONCLUSION: Next of kin who share residence and everyday life with a person with MS are affected by that person's occasional falls. They often take on the responsibility of preventing such falls and adapt their lives practically and emotionally. However, adaptation is neither always enough or always possible. In these cases, relatives often deprioritize their own needs and free time to make everyday life in the home work. Implications for rehabilitation By highlighting that next of kin also are affected by the falls of their cohabiting person with multiple sclerosis enhances the importance of fall prevention activities that should include the next of kin. Next of kin to people who occasionally fall due to multiple sclerosis can be in need of both practical and emotional support from the health care system. Enhanced information from the health care system can empower and help them to take care of themselves while managing to live with, care for, and protect the person with multiple sclerosis from falls.

AB - In late 2017 and early 2018, the New York City Department of Health and Mental Hygiene deployed multiple teams to Puerto Rico and the US Virgin Islands to support public health in those territories. This article is a description of how those teams were conceived, deployed, supported, and reintegrated into the agency. This was an unprecedented mission for our agency, and what follows is a reflection on what worked and what didn't work for us. It is our hope that other jurisdictions can use this information to organize and execute similar missions in the future, and that collectively we can continue to advance the field of public health preparedness and response. PMID- 30299169 TI - miR-155 deletion modulates lipopolysaccharide-induced sleep in female mice. AB - : Immune signaling is known to regulate sleep. miR-155 is a microRNA that regulates immune responses. We hypothesized that miR-155 would alter sleep regulation. Thus, we investigated the potential effects of miR-155 deletion on sleep-wake behavior in adult female homozygous miR-155 knockout (miR-155KO) mice and littermate controls (WT). Mice were implanted with biotelemetry units and EEG/EMG biopotentials were recorded continuously for three baseline days. miR 155KO mice had decreased bouts of NREM and REM sleep compared with WT mice, but no differences were observed in the length of sleep bouts or total time spent in sleep-wake states. Locomotor activity and subcutaneous temperature did not differ between WT and miR-155KO mice. Following baseline recordings, mice were sleep deprived during the first six hours of the rest phase (light phase; ZT 0-6) followed by an 18 h recovery period. There were no differences between groups in sleep rebound (% sleep and NREM delta power) after sleep deprivation. Following recovery from sleep deprivation, mice were challenged with a somnogen (viz., lipopolysaccharide (LPS)) one hour prior to the initiation of the dark (active) phase. Biopotentials were continuously recorded for the following 24 h, and miR 155KO mice displayed increased wakefulness and decreased NREM sleep during the dark phase following LPS injection. Additionally, miR-155KO mice had reduced EEG slow-wave responses (0.5-4 Hz) compared to WT mice. Together, our findings indicate that miR-155 deletion attenuates the somnogenic and EEG delta-enhancing effects of LPS.

PMID- 30299170 TI - Discrimination between extreme chronotypes using the full and reduced version of the Morningness-Eveningness Questionnaire. AB - The aim of this study was to carry out a comparison of the ability to discriminate between extreme chronotypes, i.e., morning- and evening-types, among the Morningness-Eveningness Questionnaire (MEQ) and its reduced version (rMEQ). To this end a secondary analysis of cohort studies, using two different approaches, was carried out. The first, subjective, relied on the computing of overlap between extreme chronotypes according to their hourly ideal bedtime, get up time and midpoint of sleep reported at the MEQ and rMEQ, while the second, objective, on the corresponding actual-actigraphic times. At the subjective approach, 2706 participants filled in the MEQ, while 940 the rMEQ (age range of both groups: 18-30 years). The overlap was significantly lower among those who filled the rMEQ than MEQ when considering ideal midpoint of sleep (13.70% and 46.28%, respectively) and get-up time (47.04% and 62.34%, respectively). At the objective approach, 51 participants filled in the MEQ while 52 the rMEQ (age range: 19-30 years in both groups) at the end of one week of actigraphic recording. No significantly different overlap across those who filled the MEQ or rMEQ was observed with reference to the examined actigraphic times. Results of subjective assessment showed as rMEQ more clearly discriminated between extreme chronotypes than MEQ. The attempt to find an objective confirmation did not provide the same results, probably as a consequence of a masking effect by social rhythms. PMID- 30299171 TI - A risk prediction model for renal damage in a hypertensive Chinese Han population. AB - : Backgroud: While numerous risk factors for renal damage in the hypertensive population have been reported, there is no single prediction model. The purpose of this study was to develop a model to comprehensively evaluate renal damage risk among hypertensive patients. Methods: We analyzed the data of 582 Chinese hypertensive patients from 1 January 2013 to 30 June 2016. Basic patient information was collected along with laboratory test results. According to the albumin-to-creatinine ratio, the subjects were divided into a hypertension with renal damage group and a hypertension without renal damage group. The prediction model was established by logistic regression based on principal component analysis, and the area under the receiver operating characteristic curve was used to evaluate the predictive performance of the model. RESULTS: There are 11 indicators have statistically significant difference between the two groups (P < 0.05); The equation expressed including all 11 risk factors was as follows: Y = ( 0.236) - 0.1705 (sex) - 0.0098 (age) - 0.1067 (smoking history) + 0.0303 (drinking history) - 0.3031 (CHD) + 0.1276 (diabetes history) - 0.0596 (CRP level) - 0.0732 (CysC level) + 0.0949 (beta2-MG level) + 0.5407 (blood pressure type) + 0.6470 (RRI). The calculated AUC was 74.4%; The risk in males was much higher than that in females of the same age. However, with increasing age, the male:female risk ratio gradually decreased. Conclusion: Eleven indicators (including sex, age, smoking history, drinking history, coronary heart disease, diabetes history, C-reactive protein, CystatinC, beta2-microglobulin protein, blood pressure type, renal artery resistance index) may be the risk factors of renal damage in hypertension. Our regression equation provides a feasible means of predicting renal damage in Chinese hypertensive populations, and the model showed good predictive power. In addition, estrogen may confer a protective effect on the kidney.

PMID- 30299172 TI - "Human Life is Inviolable": Costa Rica's Human Rights Crucible. AB - The Costa Rican Constitutional Court banned in vitro fertilization in 2000, citing the inviolability of life. Conservatives hoped the ban would initiate a hemispheric movement to protect the unborn. But in 2012 the Inter-American Court of Human Rights ruled that reproductive rights are human rights and that women's rights take precedence over embryo rights. The episode precipitated a national identity crisis: how could a country that supports universal health care be labeled a human rights violator as a result of its efforts to protect nascent human life? Expanding the health and human rights framework helps us appreciate how IVF became Costa Rica's human rights crucible. PMID- 30299173 TI - The quality of care questionnaire: development of a valid measure for persons with inflammatory bowel disease. AB - BACKGROUND AND AIMS: Quality of care is important in lifelong illnesses such as inflammatory bowel disease (IBD). Valid, reliable and short questionnaires to measure quality of care among persons with IBD are needed. The aim of this study was to develop a patient-derived questionnaire measuring quality of care in persons with IBD. METHODS AND RESULTS: The development of the questionnaire The Quality of Care -Questionnaire (QoC-Q) was based on a literature review of studies measuring quality of care, and the results of two qualitative studies aiming to identify the knowledge need and perception of health care among persons with IBD. Further development and evaluation was done by focus groups, individual testing and cognitive interviews with persons with IBD, as well as evaluation by a group of professionals. After the development, the questionnaire was tested for validity and test-retest reliability in 294 persons with IBD. CONCLUSIONS: The QoC-Q is showing promising validity and reliability for measuring the subjective perception of quality of care. Further testing in clinical practice is suggested to assess if the QoC-Q can be used to evaluate care and areas of improvement in health care for persons living with IBD. PMID- 30299174 TI - Core-shell microencapsulation of curcumin in PLGA microparticles: programmed for application in ovarian cancer therapy. AB - In our study, we have established a novel liquid-driven co-flow focusing (LDCF) process to fabricate curcumin (CUR)-loaded poly (lactic-co-glycolic acid) (PLGA) microparticles (CPMs). LDCF-CPMs of size 20.26 +/- 2.37 MUm have high encapsulation efficiency (>70%) and were intended for application in ovarian cancer by intraperitoneal (IP) administration. LDCF-CPMs have smooth surface with narrow size distribution and a core-shell structured verified by confocal microscopy which can be precisely controlled by changing the flow rates of focusing, outer and inner phases. The LDCF-CPMs reveal the physiochemical stability with sustained release profile corresponding to 95% CUR release over a period of 14 days in an in vitro release medium. Moreover, LDCF-CPMs were testified for cytotoxicity against SKOV-3 ovarian cancer cell lines and peritoneal delivery advantages by animal experiments. The pharmacokinetics of LDCF-CPMs in rats following IP injection shows slow systemic absorption with mean residence time (MRT) of 13.54 h in comparison with 9.82 and 6.74 h for SE-CPMs and free CUR, respectively. In addition, IP delivery of CUR can expose the ovarian tumour to higher concentration for a longer duration by programming the thickness of the shell. The study provides compelling evidence for LDCF-CPMs having high therapeutic opportunity in the treatment of peritoneal cancers, such as ovarian, that reside in the peritoneal cavity. PMID- 30299175 TI - Analysis of the risk factors for contrast-induced nephropathy in over-aged patients receiving coronary intervention. AB - Contrast-induced nephropathy has been the common cause of hospital-acquired acute kidney injury in the elderly patients. This study aimed to analyze the risk factors for contrast-induced nephropathy in over-aged patients undergoing coronary angiography or percutaneous coronary intervention. A total of 470 over aged patients (>=80 years old) were judged as the contrast-induced nephropathy group ( n = 46) and non-contrast-induced nephropathy group ( n = 424) according to the postoperative 48-h serum creatinine levels. The patients' clinical information such as hypertension grade, number and degree of coronary artery stenosis, and death rate was compared. The risk factors for contrast-induced nephropathy were also analyzed. The hypertension grade in the contrast-induced nephropathy group was significantly higher than that in the non-contrast-induced nephropathy group ( P = 0.004). The degree of coronary artery stenosis was significantly more in the contrast-induced nephropathy group compared with the non-contrast-induced nephropathy group ( P = 0.003). The death rate of the contrast-induced nephropathy group (15.8%) was significantly higher than that of the non-contrast-induced nephropathy group (0.6%; P = 0.000). The percentage of patients with abnormal urine microalbumin was significantly bigger in the contrast-induced nephropathy group (62.5%) when comparing to the non-contrast induced nephropathy group (23.6%; P = 0.00). Besides, there was also significant difference in the emergency/selective operation between the contrast-induced nephropathy group and non-contrast-induced nephropathy group ( P = 0.001). Further, hypertension grade ( P = 0.019), emergency/selective operation ( P = 0.025), degree of coronary artery stenosis ( P = 0.038), eGFR ( P = 0.034), and urine microalbumin ( P = 0.005) were the risk factors for contrast-induced nephropathy. Hypertension grade, emergency/selective operation, degree of coronary artery stenosis, eGFR, and urine microalbumin were the risk factors for contrast-induced nephropathy in over-aged patients receiving coronary angiography and percutaneous coronary intervention, providing guidance for the clinical prevention of contrast-induced nephropathy. Impact statement In this work, we evaluated the risk factors for contrast-induced nephropathy (CIN) in over-aged patients receiving coronary angiography (CAG) and percutaneous coronary intervention (PCI). We found that hypertension grade, emergency/selective operation, degree of coronary artery stenosis, eGFR, and urine microalbumin were the risk factors for CIN in over-aged patients receiving CAG and PCI. This study provides guidance for the clinical prevention of CIN in over-aged patients undergoing coronary intervention, highlighting that a perioperative comprehensive management strategy is needed to improve the prognosis. PMID- 30299176 TI - An exploration of the experiences and utility of functional electrical stimulation for foot drop in people with multiple sclerosis. AB - PURPOSE: Functional electrical stimulation (FES) is effective in improving walking in people with multiple sclerosis (MS) with foot drop. There is limited research exploring people's experiences of using this device. This study aims to explore the utility, efficacy, acceptability, and impact on daily life of the device in people with MS. METHODS: An interpretative phenomenological approach was employed. Ten participants who had used FES for 12 months were interviewed. Transcripts were analysed, and emergent themes identified. RESULTS: Nine participants continued to use the device. Three relevant super-ordinate themes were identified; impact of functional electrical stimulation, sticking with functional electrical stimulation, and autonomy and control. Participants reported challenges using the device; however, all reported positive physical and psychological benefits. Intrinsic and external influences such as; access to professional help, the influence of others, an individual's ability to adapt, and experiences using the device, influenced their decisions to continue with the device. A thematic model of these factors was developed. CONCLUSIONS: This study has contributed to our understanding of people with MS experiences of using the device and will help inform prescribing decisions and support the continued, appropriate use of FES over the longer term. Implications for Rehabilitation People with multiple sclerosis using functional electrical stimulation report benefits in many aspects of walking, improved psychological well-being and increased engagement in valued activities. A number of challenges impact on functional electrical stimulation use. Factors such as; a positive experience using the device, access to professional help, the influence of others, a strong sense of personal autonomy and an individual's ability to adapt, influence an individual's decision to continue using functional electrical stimulation. Clinicians prescribing functional electrical stimulation should be aware of these factors so that the right support and guidance can be provided to people with multiple sclerosis, thus improving outcomes and compliance over the long term.

PMID- 30299178 TI - A Randomized Double-Blind Trial of Ginger Root for Reducing Muscle Soreness and Improving Physical Performance Recovery Among Experienced Recreational Distance Runners. AB - Previous studies indicate that ginger root has pain-relieving properties, but these effects have not been thoroughly examined in the context of distance running. The purpose of this randomized, double-blind, placebo-controlled trial was to determine whether ginger root supplementation reduces muscle soreness and dysfunction from downhill running. Thirty-two runners (10 women, 22 men) were pair-matched and randomized to 1.425 g/day of ginger root or placebo for 5 days. A 40-minute downhill (-7.5%) run was completed on day 3. Before supplementation and at various points throughout a 5-day protocol, muscle soreness, pain-pressure threshold, vertical jump, and 1.5-mile run performance were evaluated. Differences between treatments were assessed using magnitude-based inferential statistics. Soreness while jogging likely increased to a lesser degree with ginger root from baseline to immediately postrun (Cohen's d = -0.69; 90% confidence limit [CL] [-1.50, 0.12]) and from baseline to day 5 (d = -0.72; 90% CL [-1.61, 0.16]). Ginger root had a possible small benefit on vertical jump from baseline to day 5 (d = 0.24; 90% CL [0.05, 0.44]) but likely no meaningful impact on 1.5-mile run performance. Trivial or unclear effects were found for most other outcomes. No significant differences in adverse events were observed between treatments. Ginger root possibly has moderate beneficial effects on running induced soreness but likely irrelevant effects on recovery of physical performance. Ginger represents one option for runners looking to temporarily reduce pain, although more studies are warranted to clarify its safety profile and its effects on long-term training adaptation. PMID- 30299180 TI - Cardioprotective Efficacy of Coriandrum sativum (L.) Seed Extract in Heart Failure Rats Through Modulation of Endothelin Receptors and Antioxidant Potential. AB - The present study aimed to evaluate the therapeutic and prophylactic potential of Coriandrum sativum extract in isoproterenol-induced heart failure (HF) in Wistar rats. Two weeks after the isoproterenol administration, rats developed severe impairment in left ventricular functions, reduced baroreflex sensitivity, and significant alteration in hemodynamic parameters and lipid profile. HF rats also exhibited enhanced lipid peroxidation and increased expression of endothelin receptors (ETA and ETB). Therapeutic and prophylactic treatment with C. sativum extract significantly (p < .05) improved the left ventricular functions and hemodynamic parameters and increased baroreflex sensitivity. It also inhibited lipid peroxidation, improved lipid profile, and downregulated the expression of endothelin receptors. Simvastatin treatment showed a similar cardioprotective effect. Our results suggest that C. sativum extract provides significant protection from heart failure possibly due to its ability to improve left ventricular functions and baroreflex sensitivity, attenuate lipid peroxidation, and modulate the expression of endothelin receptors. PMID- 30299179 TI - Role of microRNA-223 in the regulation of poly(ADP-ribose) polymerase in pediatric patients with Crohn's disease. AB - OBJECTIVES: Crohn's disease (CD) is a multifactorial disease, characterized by oxidant-induced tissue injury with a possible activation of poly(ADP-ribose) polymerase (PARP)-1. MicroRNAs (miRs) can offer a potential link between the genetic susceptibility, environmental and immunologic factors in the pathogenesis of CD. Previously, PARP-1 was identified as a direct target gene of miR-223 in an epithelial cell line. Our aim was to examine PARP activation and miR-223 expression in colonic biopsies of pediatric CD. To support our in vivo findings, the effect of lipopolysaccharide (LPS) on same parameters was examined in HT-29 colonic epithelial cell line. METHODS: Colonic biopsies were taken from patients with macroscopically inflamed and intact mucosa with CD and controls. LPS treated HT-29 cells served as our in vitro model. To analyze the PARP-1 expression real time PCR, Western blot and immunohistochemical analyses were used. PARP-1 enzymatic activity was assessed on the basis of poly(ADP-ribosyl)ated proteins. Expression of miR-223 was examined by real-time PCR. RESULTS: PARP-1 mRNA and miR 223 expression was significantly elevated, however, the amount of PARP-1 protein and poly(ADP-ribose) was reduced in pediatric CD compared to controls. LPS incubation did not affect the expression of PARP-1 mRNA, however, decreased miR 223 expression, and enhanced PARP-1 activity. CONCLUSIONS: In our study, we showed that the expression of miR-223 is up-regulated and poly(ADP-ribosyl)ation is reduced in pediatric patients with CD. Moreover, we confirmed their opposite change in LPS treated epithelial cells, too. These data suggest that the hypofunctionality of PARP-1 may play a potential role in the pathomechanism of CD. PMID- 30299181 TI - Ozone pollution and asthma emergency department visits in the Central Valley, California, USA, during June to September of 2015: a time-stratified case crossover analysis. AB - OBJECTIVE: The San Joaquin Valley (SJV) exceeds the state and national standards for ozone (O3). This study investigates whether short-term exposure to O3 is associated with asthma emergency department (ED) visits. METHODS: We identified 1,101 ED visits in June-September of 2015 in SJV, California, who lived within 15 km of active air monitors. Conditional logistic regression models were used to obtain the odds ratio (OR) and 95% confidence interval (CI) associated with an interquartile (IQR) increase in ozone. We explored the potential effect modification by sex (female and male), race (White, Black and Hispanic), age (2 5, 6-18, 19-40, 41-64 and > = 65) and county (Merced, Madera, Kings, Fresno and Kern). RESULTS: An IQR range (18.1 ppb) increase in O3 exposure three days before an asthma attack (lag 3) was associated with a 6.6% [OR: 1.066 (95% CI: 1.032, 1.082)] increase in the odds of having an asthma ED visit. The overall ORs differed across age groups and races/ethnicities, with strongest for children aged 6-18 years [OR: 1.219 (95% CI: 1.159, 1.280)], adults 19-40 years [OR: 1.102 (95% CI: 1.053, 1.154)] and Blacks [OR: 1.159 (95% CI: 1.088, 1.236)], respectively. O3 exposure was not positively associated with asthma ED visits for Whites, while it was for other underrepresented groups. Fresno had the highest number of asthma ED visits and positive association among all five counties. CONCLUSION: We found that O3 exposure is associated with asthma ED visits in the SJV.

AB - BACKGROUND: Globally, an estimated 370 million Indigenous peoples reside in more than 70 countries with these people commonly experiencing health care access inequity. PURPOSE: This systematic review aimed to examine the impact of Indigenous health care curriculum on entry-level health professional learners in preparation to deliver equitable health care. METHODS: Seventeen articles were identified and analyzed for: context; study design; study measures, teaching and learning delivery mode, content and duration; positive and negative learner reactions; learning gained and article quality was assessed using the Medical Education Research Study Quality Instrument. RESULTS: Most included studies described face-to-face delivery along with blended learning combining a placement in an Indigenous setting, stand-alone placements and digital learning. Descriptions of learning gained covered five domains: remembering, understanding, self-knowledge, perspective and application relating mostly to cultural awareness. Factors contributing to positive learner reactions included attitude, environment, educator skill, pedagogy and opportunities. Factors contributing to negative learner reactions included attitude and environment. CONCLUSIONS: There is a need to further explore how health professional graduates are prepared to work in Indigenous health and the appropriate measures to do this. There is opportunity to learn more about Indigenous health teaching and learning across learning domains, in mainstream clinical placements and in digital learning. PMID- 30299184 TI - Contemporary Nutrition Interventions to Optimize Performance in Middle-Distance Runners. AB - Middle-distance runners utilize the full continuum of energy systems throughout training, and given the infinite competition tactical scenarios, this event group is highly complex from a performance intervention point of view. However, this complexity results in numerous potential periodized nutrition interventions to optimize middle-distance training adaptation and competition performance. Middle distance race intensity is extreme, with 800m to 5,000m races being at ~95 to 130% of VO2max. Accordingly, elite middle-distance runners have primarily Type IIa / IIx fiber morphology and rely almost exclusively on carbohydrate (primarily muscle glycogen) metabolic pathways for producing ATP. Consequently, the principle nutritional interventions that should be emphasized are those that optimize muscle glycogen contents to support high glycolytic flux (resulting in very high lactate values, of >20mmol/L in some athletes) with appropriate buffering capabilities, while optimizing power to weight ratios, all in a macro and micro-periodized manner. From youth to elite level, middle-distance athletes have arduous racing schedules (10-25 races/year), coupled with excessive global travel, which can take a physical and emotional toll. Accordingly, proactive and integrated nutrition planning can have a profound recovery effect over a long race season, as well as optimizing recovery during rounds of championship racing. Finally, with evidence-based implementation, and an appropriate risk/reward assessment, several ergogenic aids may have an adaptive and/or performance enhancing effect in the middle-distance athlete. Given that elite middle-distance athletes undertake ~400 to 800 training sessions with 10 to 25 races/year, there are countless opportunities to implement various periodized acute and chronic nutrition-based interventions to optimize performance. PMID- 30299185 TI - Medical College of the Future: from Informative to Transformative. AB - The complexity of medical education and healthcare systems is a 'wicked problem'. Change will be a continuous iteration between evaluation and revaluation. Medicine is a social science. It is about people, societies and human interaction and communication. Medical College of the future should be developed in the light of social constructivism theories. Students from year one, day one, should be embedded in the work environment. Academic Healthcare Systems will be the norm not the exceptional. The training of students will be in all healthcare related facilities in the community. Public-private partnership in education and research will spread and become more regulated and encouraged. The students who want to be the future physicians should be selected differently. The curriculum will be more context related. Entrustable professional activities will be measured more frequently at different points of the students learning trajectory. Research and innovation will be integral to the students' learning experience. They should be exposed to how researchers think and behave and be embedded in a research environment. The medical college of the future will be using advanced technology which will be disruptive and transform existing educational models. E-Learning materials will be shared by consortia of collaborating medical colleges from all around the world. Artificial intelligence and machine learning will influence how students learn. National and international accreditation systems should ensure quality, but not stifle innovation. Physical learning spaces should reflect and express the underlying assumptions about "what is learning and teaching?". This should be reflected and expressed through the design of its buildings, infrastructure, technology, furniture and out of class learning environment. Predicting the future is difficult in a rapidly changing world. Next generation physicians should be competent in treating the next generation of patients while maintaining the health of the population. PMID- 30299186 TI - Total Energy Expenditure, Physical Activity Level, and Water Turnover of Collegiate Dinghy Sailors in a Training Camp. AB - Prior studies have examined offshore sailing and energy strategies using accurate total energy expenditure (TEE) measurement in free-living conditions. However, no research has studied energy and water requirement during dinghy class sailing such as an Olympic event with concentrated training. This study aimed to investigate the TEE, physical activity level (PAL), and water turnover (rH2O) of collegiate dinghy sailors in a training camp using the doubly labeled water (DLW) method. Eleven dinghy sailing collegiate athletes (9 males and 2 females) participated. The DLW method was used to determine the participants' TEE and PAL over 8 days (6 training, 2 non-training days). Participants trained approximately 7 h/day on water. Body fat was measured using a stable-isotope dilution method. The rH2O was estimated using deuterium turnover. The mean TEE, PAL, and rH2O were 17.30 +/- 4.22 MJ/day (4133 +/- 1009 kcal/day), 2.8 +/- 0.3 (range, 2.1 to 4.1), and 3.3+/-0.7 (range, 2.6 to 4.5) L/day, respectively. To our knowledge, this was the first study to use the DLW method to determine TEE, PAL, and rH2O as references for competitive dinghy sailors in a spring training camp. Our results may serve as a reference to assist competitive dinghy sailors in determining their required nutritional support. PMID- 30299187 TI - 2018 Consensus framework for good assessment. AB - INTRODUCTION: In 2010, the Ottawa Conference produced a set of consensus criteria for good assessment. These were well received and since then the working group monitored their use. As part of the 2010 report, it was recommended that consideration be given in the future to preparing similar criteria for systems of assessment. Recent developments in the field suggest that it would be timely to undertake that task and so the working group was reconvened, with changes in membership to reflect broad global representation. METHODS: Consideration was given to whether the initially proposed criteria continued to be appropriate for single assessments and the group believed that they were. Consequently, we reiterate the criteria that apply to individual assessments and duplicate relevant portions of the 2010 report. RESULTS AND DISCUSSION: This paper also presents a new set of criteria that apply to systems of assessment and, recognizing the challenges of implementation, offers several issues for further consideration. Among these issues are the increasing diversity of candidates and programs, the importance of legal defensibility in high stakes assessments, globalization and the interest in portable recognition of medical training, and the interest among employers and patients in how medical education is delivered and how progression decisions are made. PMID- 30299188 TI - Spectacle Compliance and Its Determinants in a School Vision Screening Pilot in Botswana. AB - PURPOSE: The effectiveness of school eye health programmes relies on many factors, including compliance with spectacle wear. The objectives of this study were to determine spectacle compliance in a school vision screening pilot programme in Botswana, and investigate factors predictive of compliance. METHODS: The study was an observational, cross-sectional follow-up of a pilot school screening programme. Unannounced compliance checks were completed after 3-4 months in a convenience sample of 19 schools. Sex, age, school level, visual acuity, and refractive error were analysed using logistic regression to investigate factors predictive of compliance. FINDINGS: Compliance data were recorded for 193/286 (67.5%) children; 62.2% were female and the median age was 15 years (interquartile range 12-17 years). 60.1% of the sample were compliant with spectacle wear. Girls were more likely to be compliant than boys (adjusted odds ratio (aOR) = 2.32, 95% confidence interval (CI) 1.03-5.27). Children at primary and junior secondary school were more likely to be complaint than senior secondary school children (aOR = 16.96, 95% CI 5.60-51.39; and aOR = 3.39, 95% CI 1.39-8.22, respectively). Children with binocular uncorrected visual acuity (UCVA) of 6/7.5 to 6/12 were 2.76 (95% CI1.05-7.23) times more likely to be compliant than children with binocular UCVA of 6/6. CONCLUSION: Compliance was higher in Botswana than previous African studies; however, improvement in this area would increase the effectiveness of the programme. Further investigation into barriers to spectacle wear affecting boys and older children is warranted. A prescribing protocol to avoid low prescriptions - especially where binocular UCVA is 6/6 - is desirable. PMID- 30299189 TI - Preclinical Pharmacokinetics of a Novel anti-c-Met Antibody-Drug Conjugate, SHR A1403, in Rodents and Non-human Primates. AB - 1. The in vivo pharmacokinetics (PK) profiles of a novel c-Met antibody-drug conjugate (ADC), SHR-A1403, were investigated and characterized in mice, rats and monkeys. 2. Serum concentrations of ADC and total antibody were detected using validated ELISA methods. The results showed low systemic clearance of both ADC and total antibody in all three species as reflected by gradual decrease in serum concentrations. Half-life (t1/2) of ADC ranged from 4.6 to 11.3 days in the three species. 3. Tissue distribution study in tumor-bearing mice showed high accumulation of 125I-SHR-A1403 in tumor tissues over the other organs/tissues, indicating the favourable safety of SHR-A1403 and characteristics of an ADC drug. 4. Relatively low grade of anti-drug antibody (ADA) in monkeys had no impact on PK profile of the ADC. 5. During discovery stage, undesirable exposure and/or ADA incidence were observed for SHR-A1403 with high or low drug-antibody ratio (DAR), which was DAR = 5 to 6 and DAR = 1, respectively, and therefore prompted selection of an appropriate DAR value (DAR = 2) for SHR-A1403 used in preclinical development and clinical trials. 6. In conclusion, our work demonstrated favourable PK characterization of SHR-A1403, and supported for investigational new drug application (IND) and the ongoing first-in-human trial in the US. PMID- 30299190 TI - Observing neck movements evokes an excitatory response in the sympathetic nervous system associated with fear of movement in patients with chronic neck pain. AB - The objective of this study was to evaluate the response of the sympathetic excitatory nervous system in patients with chronic neck pain compared with a control group of asymptomatic subjects who underwent an intervention of watching activities involving movements in the neck region. Thirty participants were divided into two groups: patients with chronic neck pain (n = 15) and the control group (n = 15). The patients' neck disability, fear of movement and catastrophism were assessed with a self-report. The recorded variables related to the autonomic nervous system were skin conductance and skin temperature. The ANOVA test revealed significant differences in the increase in skin conductance in the chronic neck pain group after observing the activities (both in the photographs and video) at the end of the observation and 5 minutes after the intervention (p < .01; d > 0.80). There were no significant differences in skin temperature. Ultimately, the correlation analysis revealed a moderate positive correlation between kinesiophobia and skin conductance at 30 seconds (r = 0.53) and at 60 seconds (r = 0.52) of observing the activities in the video for the chronic neck pain group. Based on the results of the present study, we suggest that observing activities involving neck movements causes an activation of the sympathetic excitatory nervous system in patients with chronic neck pain. These changes could be related to a fear of movement when faced with visual exposure to neck movements that could be interpreted as 'harmful' or 'dangerous'. PMID- 30299191 TI - The clarion call for a third wave in medical education to optimise healthcare in the twenty-first century. AB - During the years preceding 1910, the education and training of physicians (doctors) -to-be was based mainly on a master-apprentice model; the primary focus then was on the teaching and development of clinical skills. In 1910, however, Abraham Flexner submitted a highly influential report to the American medical authorities: in it, he recommended that all medical schools should be university based and that, importantly, medical practice should have a scientific basis strongly underpinned by the basic medical sciences. The recommendation provided the impetus for the design of medical education that begins with a pre-clinical phase to provide the strong scientific foundation for the clinical phase that follows. During the clinical phase, student learning will focus primarily on the clinical sciences relating to the diagnosis, treatment and management of patient care. Thus, two key 'pillars' (the basic sciences and the clinical sciences) of medical education were established; this two pillar model of medical education persisted for many decades thereafter and remained so till today. However, in order to optimise delivery of health care this must be viewed as an 'eco-system' taking into account the practice setting both present and future. The authors will attempt to provide a background to the changing trends in medical education and the changing practice environment, due primarily to the disruptive forces of change in this article. PMID- 30299192 TI - Sports Foods and Dietary Supplements for Optimal Function and Performance Enhancement in Track and Field Athletes. AB - Athletes are exposed to numerous nutritional products, attractively marketed with claims of optimizing health, function and performance. However, there is limited evidence to support many of these claims, and the efficacy and safety of many products is questionable. The variety of nutritional aids considered for use by track and field athletes includes sports foods, performance supplements and therapeutic nutritional aids. Support for sports foods, and five evidence-based performance supplements (caffeine, creatine, nitrate/beetroot juice, beta-alanine and bicarbonate) varies according to the event, the specific scenario of use and the individual athlete's goals and responsiveness. Specific challenges include developing protocols to manage repeated use of performance supplements in multi event or heat-final competitions or the interaction between several products which are used concurrently. Potential disadvantages of supplement use include expense, false expectancy and the risk of ingesting banned substances sometimes present as contaminants. However, a pragmatic approach to the decision-making process for supplement use is recommended. We conclude that it is pertinent for sports foods and nutritional supplements to be considered only where a strong evidence-base supports their use as safe, legal and effective; and that such supplements are trialed thoroughly by the individual before committing to use in a competition setting. PMID- 30299193 TI - Differences in foot contact times between obese and non-obese postmenopausal women when crossing obstacles. AB - OBJECTIVE: This study aimed to investigate the foot contact time differences between obese and non-obese subjects during walking when crossing obstacles. METHODS: Ninety-eight postmenopausal women were assigned to four groups, and their plantar pressure temporal data were collected using a two-step protocol during walking when crossing an obstacle set at 30% height of lower limb length of each subject. The initial, final, and duration of contact of 10 foot areas were measured. RESULTS: Leading limb: (1) the heel groups initiated foot contact using the heel, and the non-heel groups initiated contact using the metatarsals; (2) heel obese subjects showed an earlier initial contact and a longer contact duration of metatarsals 2-3; (3) non-heel obese subjects showed an earlier midfoot initial contact. Regarding the trailing limb: (4) heel obese subjects showed an earlier midfoot initial contact and a longer contact duration of metatarsal 5; (5) non-heel obese subjects showed an earlier initial contact and a longer contact duration of metatarsals 4-5. CONCLUSIONS: (1) The non-heel groups' foot rollover pattern may result from an attempt of rapidly restoring stability; (2) the heel obese subjects seem to regulate their plantar foot muscles to overcome their overweight; (3) the overweight of the non-heel obese subjects leads to a quicker backward foot roll-over from the metatarsals to the heel; (4) the overweight of the heel obese subjects can distort their footprints and/or their higher inertia may precipitate an anticipation of the midfoot contact, which can also explain the result observed for 5. PMID- 30299194 TI - MiR-216a inhibits proliferation and promotes apoptosis of human airway smooth muscle cells by targeting JAK2. AB - OBJECTIVE: Accumulating evidence suggests that aberrantly expressed microRNAs in airway smooth muscle (ASM) cells could change airway remodeling during the development of asthma. However, the underlying functions of microRNAs in ASM cell proliferation and apoptosis need to be further elucidated. METHODS: By using RT qPCR, miR-216a expression level was examined in the asthmatic patients and non asthmatic individuals. Cell proliferation assay and flow cytometry analysis were used in ASM cells in which miR-216a was an abnormal expression. MiR-216a predicted to target gene was explored by bioinformatic software, and further analyzed by Western blotting and luciferase reporter assay. RESULTS: Our results demonstrated that miR-216a levels were considerably lower in the ASM cells of asthmatic patients than in those of non-asthmatic individuals. Further study verified that the overexpression of miR-216a markedly suppressed cell proliferation and promoted cell apoptosis, whereas the knockdown of miR-216a had opposite effects in ASM cells. In addition, luciferase reporter assays and Western blotting identified that JAK2 was the direct functional target of miR 216a, and the ectopic expression of JAK2 partially rescued the inhibitory effect of miR-216a in ASM cells. CONCLUSIONS: The above data indicate that miR-216a may function as a key regulator of airway remodeling by targeting JAK2, thus suggesting the potential role of miR-216a in the pathogenesis of asthma. PMID- 30299195 TI - What's in Your Beet Juice? Nitrate and Nitrite Content of Beet Juice Products Marketed to Athletes. AB - Consumption of beetroot juice (BRJ) supplements has become popular among athletes, because beets tend to be rich in nitrate (NO3-), which can enhance exercise performance by increasing nitric oxide production. The NO3- content of beets can vary significantly, however, making it difficult to know how much NO3- any product actually contains. Samples from 45 different lots of 24 different BRJ products from 21 different companies were therefore analyzed for NO3- (and nitrite; NO2-) concentration using high performance liquid chromatography. The NO3- and NO2- content, i.e., amount per serving, was then calculated based on either 1) the manufacturer's recommended serving size (for prepackaged/single dose products) or 2) as used in previous studies, a volume of 500 mL (for BRJ sold in bulk containers). There was moderate-to-large variability in NO3- content between samples of the same product, with a mean coefficient of variation of 30+/ 26% (range 2 to 83%). There was even greater variability between products, with a ~50-fold range in NO3- content between the lowest and highest. Only five products consistently provided >=5 mmol of NO3- per serving, which seems to be the minimal dose required to enhance exercise performance in most individuals. NO2- contents were generally low (i.e., <=0.5% compared to NO3-), although two products contained 10 and 14%. The present results may be useful to athletes and their support staff contemplating which (if any) BRJ product to utilize. These data may also offer insight into variability in the literature with respect to the effects of BRJ on exercise performance. PMID- 30299196 TI - Plus CA Change, plus C'Est Pareil: Making a Continued Case for the Use of MCQs in Medical Education. AB - Despite the increased emphasis on the use of workplace-based assessment in competency-based education models, there is still an important role for the use of multiple choice questions (MCQs) in the assessment of health professionals. The challenge, however, is to ensure that MCQs are developed in a way to allow educators to derive meaningful information about examinees' abilities. As educators' needs for high-quality test items have evolved so has our approach to developing MCQs. This evolution has been reflected in a number of ways including: the use of different stimulus formats; the creation of novel response formats; the development of new approaches to problem conceptualization; and the incorporation of technology. The purpose of this narrative review is to provide the reader with an overview of how our understanding of the use of MCQs in the assessment of health professionals has evolved to better measure clinical reasoning and to improve both efficiency and item quality. PMID- 30299197 TI - Twelve Tips for Developing Clinical Reasoning Skills in the Pre-Clinical and Clinical Stages of Medical School. AB - Clinical reasoning (CR) is a complex skill required in future clinicians. The best way to develop CR has not been fully elucidated in existing literature. Barriers to CR development include content, environmental, and teacher or expert physician factors. We have reviewed literature, interviewed medical students and teaching staff at the University of Nottingham, and evaluated our teaching delivery. We identified twelve strategies to combat barriers to CR learning at our university. The foundation for CR must be built early through lectures and case-based learning. We emphasize the irreplaceable nature of ward-based learning and add on methods of optimizing time on wards. Placement on acute wards with trained teaching staff to facilitate CR teaching was suggested. Ward time should be supplemented with symptom-focused teaching, patient workshops, simulation sessions, virtual case banks, and clinical skills practice. However, ward time is the utmost priority and must not be replaced. PMID- 30299198 TI - Epicatechin Supplementation and Resistance Training-Induced Improvement of Muscle Strength and Circulatory Levels of Plasma Follistatin and Myostatin in Sarcopenic Older Adults. AB - To investigate the effects of resistance training and Epicatechin supplementation on muscle strength, follistatin and myostatin in sarcopenic older adults, 62 sarcopenic males (68.63+/-2.86 years) underwent a supervised 8-week randomized controlled trial. Participants were divided into Resistance Training (RT), Epicatechin (EP), Resistance Training+Epicatechin (RT+EP), and Placebo (PL) in a double-blind method. A pretest and posttest measurement was conducted. One-way ANOVA was used to analyze between-group differences. Significantly greatest increase was observed in follistatin, follistatin/myostatin ratio, leg-press, and chest-press in RT+EP comparing RT, EP and, PL groups whereas, myostatin decreased significantly only in RT+EP and RT groups, however, appMMI and TUG enhanced significantly in all experimental groups than the PL group (P<=0.05). Consequently, by comparing the results between three experimental groups, the greatest improvement was detected in RT+EP group. Therefore, using two interventions simultaneously seems to have better impacts on improving muscle growth factors and preventing the progression of sarcopenia. PMID- 30299199 TI - Stress Relaxation and Targeted Nutrition to Treat Patellar Tendinopathy. AB - Patellar tendinopathy is one of the most common afflictions in jumping sports. This case study outlines the rehabilitation of a professional basketball player diagnosed by MRI with a central core patellar tendinopathy within the proximal enthesis. The player undertook a nutrition and strength based rehabilitation program combining gelatin ingestion and heavy isometric loading of the patella designed to produce significant stress relaxation as part of their competition schedule and a whole body training plan. On follow up one and a half years into the program an independent orthopedic surgeon declared the tendon normal on MRI. Importantly, the improved MRI results were associated with a decrease in pain and improved performance. This case study provides evidence that a nutritional intervention combined with a rehabilitation program that uses stress relaxation can improve clinical outcomes in elite athletes. PMID- 30299200 TI - The Magnitude of Rapid Weight Loss and Rapid Weight Gain in Combat Sport Athletes Preparing for Competition: A Systematic Review. AB - Combat sport athletes typically engage in a process called making-weight, characterised by rapid weight loss (RWL) and subsequent rapid weight gain (RWG) in the days preceding competition. These practices differ across each sport, but no systematic comparison of the size of the changes in body mass exists. The aim was to determine the magnitude of RWL and RWG in combat sport athletes preparing for competition. The review protocol was preregistered with PROSPERO [CRD42017055279]. In eligible studies, athletes prepared habitually with a RWL period <=7 days preceding competition. An electronic search of EBSCOhost (CINAHL Plus, MEDLINE, SPORTDiscus) and PubMed Central was performed to July 2018. Sixteen full-text studies (total 4432 participants, 156 female, 4276 male) were included, providing data from five combat sports (boxing, judo, mixed martial arts (MMA), taekwondo and wrestling). Three studies reported RWL and fourteen studies reported RWG. Duration permitted for RWG ranged 3-32 hours. The largest changes in body mass occurred in two separate MMA cohorts (RWL 7.4 +/- 1.1kg [~10%], RWG 7.4 +/- 2.8kg [11.7 +/- 4.7%]). The magnitude of RWG appears to be influenced by the type of sport, competition structure, and recovery duration permitted. A cause for concern is the lack of objective data quantifying the magnitude of RWL. There is insufficient evidence to substantiate the use of RWG as a proxy for RWL, and little data are available in females. By engaging in RWG, athletes are able to exploit rules to compete up to three weight categories higher than at the official weigh-in. PMID- 30299201 TI - Test-retest reliability of subjective supra-threshold scaling of multiple pressure-pain sensations among healthy individuals: a study using hydraulic pressure algometry. AB - BACKGROUND: Supra-threshold scaling of multiple pressure-pain sensations involves delivery of varied stimulus intensities, either via stimulus-dependent or response-dependent manner, and recording of subjective pain ratings by participants. The focus of this study was to determine the intra- and inter session reliability of pain intensity and pain unpleasantness ratings related to pressure-pain thresholds (PPTs) of just noticeable pain (JNP), weak pain (WP) and moderate pain (MP) among healthy individuals. METHODS: Fourteen healthy participants (eight women, six men) participated in three sessions of testing at varied intervals over the course of 72 h. In session one, a multiple random staircase method using hydraulic pressure algometry was used to measure PPT of JNP, WP and MP on thumbnail bed. In session 2, ratings of pain intensity and pain unpleasantness were recorded when stimuli at levels corresponding to PPT of JNP, WP and MP were repeatedly applied before and after 20 min of no intervention. RESULTS: Interclass correlation coefficient (ICC) values for pain ratings of JNP, WP and MP in intra-session reliability were 0.810, 0.826 and 0.881, respectively, whereas the values were 0.817, 0.792 and 0.910, respectively, for inter-session reliability. ICC values for pain unpleasantness were also highly consistent and repeatable. Temporal summation of pain intensity and pain unpleasantness were not related to the repeated application of pressure stimuli. CONCLUSIONS: The findings indicate that the pain intensity and pain unpleasantness ratings for stimuli at levels equal to the thresholds of JNP, WP and MP have good intra- and inter-session reliability. SIGNIFICANCE: This study showed that both pain intensity and pain unpleasantness of JNP, WP and MP have good intra- and inter session reliability and agreement. Furthermore, the temporal summation of pain or unpleasantness is not related to repeated application of pressure stimuli. ABBREVIATIONS: JNP: Just noticeable pain; WP: Weak pain; MP: Moderate pain; PPTs: pressure-pain thresholds; HPA: Hydraulic pressure algometry; MRSM: multiple random staircase method. PMID- 30299202 TI - Long-Term Safety and Efficacy of Weekly Subcutaneous Tocilizumab Monotherapy in Patients With Rheumatoid Arthritis Who Had an Inadequate Response to Subcutaneous Tocilizumab Every Other Week: Results From the Open-Label Extension of the SHINOBI Study. AB - OBJECTIVE: To evaluate the long-term safety and efficacy of subcutaneous tocilizumab (TCZ-SC) monotherapy administered weekly (qw) in patients with rheumatoid arthritis who had an inadequate response to TCZ-SC every other week (q2w). METHODS: Patients who completed 12 weeks of double-blind treatment with either TCZ-SC q2w monotherapy or TCZ-SC qw monotherapy were switched to or continued to receive open-label treatment with TCZ-SC qw monotherapy for 40 weeks. Safety and efficacy were assessed. Subgroup analyses of Disease Activity Score based on 28 joints using erythrocyte sedimentation rate (DAS28-ESR) were performed at 12 weeks. RESULTS: The incidence of adverse events was 464.4/100 patient-years (PY). The incidence of infection was 121.3/100 PY. The safety profile of TCZ-SC qw monotherapy was consistent with that of prior studies of TCZ. No additional safety concerns were observed. Improvement from baseline in DAS28-ESR was maintained at week 52 in patients who continued TCZ-SC qw and improved in patients who switched from TCZ-SC q2w to qw. At week 12, the efficacy of TCZ-SC qw monotherapy was greater than that of TCZ-SC q2w monotherapy irrespective of weight and BMI subgroups. CONCLUSION: The long-term weekly dosing of TCZ-SC monotherapy was well tolerated and efficacy was maintained over 52 weeks. PMID- 30299203 TI - Antioxidative Effects of Piperine against Cadmium-Induced Oxidative Stress in Cultured Human Peripheral Blood Lymphocytes. AB - Cadmium (Cd) has a remarkable property of generating oxidative stress. It upregulates the level of reactive oxygen species, which generates damage to lipids, proteins, and DNA The level of oxidative stress by Cd is observed by inhibitory effects of antioxidant enzymes such as catalase, superoxide dismutase, glutathione reductase, and glutathione peroxidase. Piperine is one of the plant derived alkaloids isolated from Piper nigrum and Piper longum. It diminishes the level of oxidative damage by quenching the free radicals and reactive oxygen species and inhibiting the lipid peroxidation. It is well known to induce stress proteins, including metallothionein (MT), a metal-binding protein and heat shock protein (HSP70). In the present work, antioxidative effects of piperine have been studied against Cd-induced oxidative stress. We observed its ameliorative effects using various biomarkers, such as comet and lipid peroxidation (LPA) assays in cultured human peripheral blood lymphocytes from healthy individuals. Piperine at 35 and 50 uM concentrations significantly reduces the tail moment and peroxidation of lipids. We also explored the relationship of MT2A gene polymorphism on oxidative and antioxidative effects of Cd and piperine, respectively. At selected concentration, we observed a decrease in the mean value of tail moment and lipid peroxidation level. However, the overall effect was statistically nonsignificant (p > .05). PMID- 30299204 TI - Twelve tips for clinicians dealing with uncertainty when assessing learners. AB - Clinician educators often experience distress caused by uncertainty regarding how effectively to participate in assessment practices in a way that supports both their programs and their students. Uncertainty is a common state for clinicians, particularly for those who see patients with early or ill-defined illness presentations. While clinicians often feel ill at ease when facing uncertainty in the clinical realm, becoming comfortable with uncertainty and learning to manage such states are now recognized as vital components of clinical practice. Clinicians, as a result, have adopted a series of strategies to lessen the unease that uncertainty can create. While similar experiences plague clinician educators placed in assessment roles, much less attention has been given to how we can support individuals in the education setting. Here, the distress of uncertainty may be greater due to clinician educators having less experience with assessment practices. Fortunately, strategies that are effective in the clinical domain can be translated into the assessment realm to accommodate uncertainty when assessing learners. In this 12 tips article we offer guidance on the translation of such strategies. PMID- 30299206 TI - Physical Activity Attitudes, Preferences, and Experiences of Regionally-Based Australia Adults 65+ Years. AB - An understanding of physical activity attitudes, preferences, and experiences in older adults is important for informing interventions. Focus groups were conducted with 46 regionally-based Australian adults aged 65 years and older who were not currently meeting activity recommendations. Content analysis revealed that participants mainly engaged in incidental activities such as gardening and household chores rather than planned exercise; however, leisure time walking was also mentioned frequently. While participants valued the physical and mental health benefits of physical activity, they reported being restricted by poor physical health, extreme weather and fear of injury. Participants were interested in exercise groups and physical activity programs tailored to their existing physical health. The majority of participants reported preferring to be active with others. The findings from this study are useful in for informing future interventions specifically tailored to the needs of older adults in Australia. PMID- 30299207 TI - Human amniotic membrane as differentiating matrix for in vitro chondrogenesis. AB - AIM: The aim of the present study is to use human amniotic membrane (HAM) for in vitro chondrogenesis of placenta-derived mesenchymal stem cells (MSCs) and umbilical cord-derived MSCs. MATERIALS & METHODS: MSCs from the placenta and umbilical cord were isolated, characterized by immunophenotyping and after analyzing their rate of proliferation, cytotoxicity and viability, chondrogenesis was performed on plastic adherent surface and on HAM. RESULTS: Successfully isolated and characterized placenta-derived MSCs and umbilical cord-derived MSCs revealed positive expression of MSCs markers CD90, CD73, CD105 and CD49d, while they were negative for CD45. Both types of cells in the presence of chondrogenic induction medium on plastic adherent surface and HAM showed aggregates of proteoglycan and strong expression of COL2A1 (collagen 2) and ACAN1 (aggrecan). CONCLUSION: HAM supported proliferation as well as chondrogenesis of MSCs and provide novelty of HAM utilization as an efficient natural delivery matrix for stem cell transplantation. PMID- 30299205 TI - Integration of genomics, high throughput drug screening, and personalized xenograft models as a novel precision medicine paradigm for high risk pediatric cancer. AB - Pediatric high grade gliomas (HGG) are primary brain malignancies that result in significant morbidity and mortality. One of the challenges in their treatment is inter- and intra-tumoral heterogeneity. Precision medicine approaches have the potential to enhance diagnostic, prognostic and/or therapeutic information. In this case study we describe the molecular characterization of a pediatric HGG and the use of an integrated approach based on genomic, in vitro and in vivo testing to identify actionable targets and treatment options. Molecular analysis based on WGS performed on initial and recurrent tumor biopsies revealed mutations in TP53, TSC1 and CIC genes, focal amplification of MYCN, and copy number gains in SMO and c-MET. Transcriptomic analysis identified increased expression of MYCN, and genes involved in sonic hedgehog signaling proteins (SHH, SMO, GLI1, GLI2) and receptor tyrosine kinase pathways (PLK, AURKA, c-MET). HTS revealed no cytotoxic efficacy of SHH pathway inhibitors while sensitivity was observed to the mTOR inhibitor temsirolimus, the ALK inhibitor ceritinib, and the PLK1 inhibitor BI2536. Based on the integrated approach, temsirolimus, ceritinib, BI2536 and standard therapy temozolomide were selected for further in vivo evaluation. Using the PDX animal model (median survival 28 days) we showed significant in vivo activity for mTOR inhibition by temsirolimus and BI2536 (median survival 109 and 115.5 days respectively) while ceritinib and temozolomide had only a moderate effect (43 and 75.5 days median survival respectively). This case study demonstrates that an integrated approach based on genomic, in vitro and in vivo drug efficacy testing in a PDX model may be useful to guide the management of high risk pediatric brain tumor in a clinically meaningful timeframe.

AB - Botrytis cinerea, the causal agent of gray mold, can result in considerable preharvest and postharvest losses in many economically valuable plant species. Fungicides were widely used to minimize such losses, but fungicide resistances were detected frequently. In the present study, we collected 164 isolates from nectarine and cherry in China and tested the sensitivity to six fungicides. Among the tested isolates, 71 (43.3%) were resistant to azoxystrobin, 14 (8.5%) to cyprodinil, 7 (4.3%) to boscalid, 4 (2.4%) to carbendazim, 1 (0.6%) to iprodione, and no isolates were found to be resistant to fludioxonil. The EC50 value and resistance factor (RF) of resistant isolates were determined. Fitness analysis showed that there were no significant differences between sensitive and resistant isolates for osmotic stress and pathogenicity, while more conidia production was observed for some resistant isolates. Control efficacy of fungicides showed that the resistant isolates could not be controlled efficiently by using corresponding fungicides. The point mutation G143A was detected in the Cyt b gene of the isolates resistant to azoxystrobin, while the point mutation H272R of SdhB gene was confirmed in boscalid-resistant isolates, and mutations E198V/A of TUB2 gene and mutation I365S of BcOs1 occurred in carbendazim-resistant and iprodione resistant isolates, respectively. These results indicate that the occurrence of fungicide resistance greatly threatens the management of gray mold on stone fruits nectarine and cherry. PMID- 30299209 TI - Global role for coactivator complexes in RNA polymerase II transcription. AB - SAGA and TFIID are related transcription complexes, which were proposed to alternatively deliver TBP at different promoter classes. Recent genome-wide studies in yeast revealed that both complexes are required for the transcription of a vast majority of genes by RNA polymerase II raising new questions about the role of coactivators. PMID- 30299210 TI - Application of a novel nanoemulsion adjuvant for rabies vaccine which stabilizes a Krebs cycle intermediate (SDH) in an animal model. AB - Rabies is the most lethal zoonotic, vaccine-preventable viral disease in the world. Its treatment is complicated by insufficient vaccine supply and the requirement for four to five repeated injections, as commercially available inactivated rabies lack adjuvant and have low immunogenicity. In this study, we focused on the role of a Krebs cycle intermediate, succinate dehydrogenase (SDH), in the innate immune response to cytokine production. We formulated a novel nanoemulsion adjuvant, Golden03, which stabilizes mouse SDH activity and contains more coenzyme Q10 and succinic acid than the classic MF59 adjuvant. Mice were immunized on days 1, 3, and 7, with seroconversion rate results suggesting that Golden03 significantly enhanced vaccine-stimulated antibody production against the rabies virus. Neutralizing antibody concentration testing by RFFIT indicated that treatment with Golden03 could result in antibody levels of up to 0.74 IU/mL 5 days post infection (DPI). ELISPOT for IFN-gamma in mouse spleen cells showed that Golden03 enhanced immune responses at 14 DPI, inducing a rapid and powerful cellular response compared to the control group. Furthermore, the Vaccine Golden03 group displayed no obvious weight loss or death after intracranial injection with CVS-11. An additional advantage is that Golden03 allowed for a three-quarter reduction in dose, while maintaining its efficacy and rapid stimulation effect. We suggest that Golden03 could be developed as a potential adjuvant for use in human rabies vaccine. PMID- 30299211 TI - MiRNA-155 regulates lymphangiogenesis in natural killer/T-cell lymphoma by targeting BRG1. AB - BACKGROUND: miR-155 was up-regulated in natural killer/T-cell lymphoma (NKTCL), an aggressive malignancy, and correlated with disease progression. However, minimal is known on biological activities and underlying mechanisms of miR-155 in NKTCL. In this study, we examined BRG1, a potential target of miR-155, and focused on the miR-155/BRG1 signaling in regulating lymphangiogenesis of NKTCL. METHODS: The expression of miR-155, BRG1, VEGFC, and VEGFD was compared between two NKTCL cell lines and normal NK cells. The critical role of miR-155 and STAT3 was assessed using miR-155 inhibitor and STAT3 inhibitor S31-201, respectively. Two biological phenotypes, apoptosis and pro-lymphangiogenesis, were examined in vitro by flow cytometry and lymphatic tube formation, respectively, and in vivo using an NKTCL xenograft model. RESULTS: The miR-155 level negatively correlated with BRG1, but positively with VEGFC in normal NK as well as two NKTCL cell lines. Targeting miR-155 in NKTCL cells significantly boosted BRG1 expression and decreased the activated STAT3 or VEGFC level, leading to enhanced apoptosis and reduced lymphangiogenesis. STAT3 acted downstream of BRG1 and essentially regulated miR-155-mediated up-regulation of VEGFC and pro-lymphangiogenesis. In vivo, targeting miR-155 inhibited primary xenograft growth as well as tumor associated lymphangiogenesis. CONCLUSIONS: By inhibiting BRG1 expression, miR-155 activated STAT3/VEGFC signaling and promoted lymphangiogenesis. In addition, miR 155 also controlled the viability of NKTCL cells. Therefore, targeting miR-155 provides a novel therapy for NKTCL. PMID- 30299212 TI - Reasons for attempting suicide: An exploratory study in Ghana. AB - This study examined the reasons for suicide attempts among patients in Ghana. Semi-structured interviews were conducted among 30 informants who had been hospitalized for attempted suicide. Interpretative Phenomenological Analysis (IPA) was used to analyse the transcribed narratives, and five main themes emerged: 1) lack of support; 2) abandonment; 3) shame; 4) existential struggles; and 5) supernatural reasons. There were gender differences with abandonment reported by only women and shame associated with economic difficulties reported only by men. Findings are discussed within the context of a socio-cultural theory of suicide behaviour, and implications for the prevention of suicide and care of suicidal persons are suggested. PMID- 30299213 TI - Regulation of Plant Immune Signaling by Calcium-Dependent Protein Kinases. AB - Activation of Ca2+ signaling is a universal response to stress that allows cells to quickly respond to environmental cues. Fluctuations in cytosolic Ca2+ are decoded in plants by Ca2+-sensing proteins such as Ca2+-dependent protein kinases (CDPKs). The perception of microbes results in an influx of Ca2+ that activates numerous CDPKs responsible for propagating immune signals required for resistance against disease-causing pathogens. This review describes our current understanding of CDPK activation and regulation, and provides a comprehensive overview of CDPK-mediated immune signaling through interaction with various substrates. PMID- 30299214 TI - Influence of deployment time and surface wind speed on the accuracy of measurements of greenhouse gas fluxes using a closed chamber method under low surface wind speed. AB - As a convenient method, the closed chamber method has been applied to determine gaseous emission fluxes from fully open animal feeding operations despite the measured fluxes being theoretically affected by deployment time, wind speed over the emitting surface and detected gas mass. This laboratory study evaluated the effects of deployment time (0 to 120 min) and external surface wind speed (ESWS) (0.00, 0.25, 0.50, 0.75, 1.00, 1.50 and 2.00 m sec-1) on the measurement accuracy of a 300 mm (diameter) * 400 mm (height) (D300*H400) closed chamber using methane (CH4), nitrous oxide (N2O) and sulfur hexafluoride (SF6) as reference gases. The results showed that the overall deviation ratio between the measured and reference CH4 fluxes ranged from 9.99 % to -37.32 % and the flux was overestimated in the first 20 min. The measured N2O and SF6 emissions were smaller than the reference fluxes using the chamber. N2O measurement accuracy decreased from -14.47 to -35.09% with deployment time extended to 120 min, while SF6 accuracy sharply increased in the first 40 min, with the deviation stabilizing at approximately -5.00%. CH4, N2O and SF6 measurements were significantly affected by deployment time and ESWS (P<0.05), and the interaction of those two factors greatly influenced CH4 and SF6 measurements (P<0.05). With the D300*H400 closed chamber, deployment times of 20 to 30 min and 10 to 20 min are recommended to measure CH4 and N2O, respectively, from the open operations of dairy farms under wind speeds lower than 2 m sec-1. Implications: This study recommended the suitable deployment times and wind speeds for using a D300 * H400 closed chamber to measure CH4, N2O, and SF6 in an open system, such as a dairy open lot and manure stockpile, to help researchers and other related industry workers get accurate data for gas emission rate. Deployment times of 20 to 30 min and 10 to 20 min were recommended to measure CH4 and N2O emissions using the D300 * H400 closed chamber, respectively, from the open operations of dairy farms under wind speeds lower than 2 m sec-1. For the measurement of SF6, a typical tracer gas, a deployment of 70 to 90 min was suggested. PMID- 30299215 TI - Pulmonary adverse events related to idelalisib therapy: A single centre experience. AB - Idelalisib is a potent and selective inhibitor of the PI3Kdelta approved since September 2014 for the treatment of several types of B cell malignancies. Pulmonary adverse events related to idelalisib are an emerging serious adverse event. We report here a single centre cohort of 16 patients who initiated idelalisib as routine treatment. Five of them experienced severe pulmonary adverse events related to idelalisib therapy. Comparison of the 5 patients with severe pulmonary events versus the 11 patients without identified no predisposing factors. Severe pulmonary adverse events were related to infectious pneumonia and/or to a drug-induced pneumonitis. The mechanisms of idelalisib-associated pneumonitis are unknown but consistent with the drug-induced pneumonitis described with mTOR inhibitors. Indeed, by inhibiting PI3Kdelta, idelalisib also inhibits the mTOR pathway. Clinicians should be aware that any idelalisib-treated patient who presents with pulmonary symptoms should be evaluated for pneumonitis. Corticosteroids should be considered in addition to anti-infective therapy in case of severe pneumonitis or persistent pulmonary symptoms despite adequate antibiotic therapy. PMID- 30299216 TI - Augmentation cystoplasty in neuropathic bladder. AB - OBJECTIVES: To look at the changing role of cystoplasty in the neuropathic population. DESIGN: Retrospective case series. SETTING: Single center over a 10 year period from 2004 to 2014. PARTICIPANTS AND INTERVENTION: In 1995, the Princess Royal spinal injuries unit published the outcomes of 78 neuropathic patients who had undergone cystoplasty in the 10-year period from 1982 to 1992. [Singh G, Thomas DG. Enterocystoplasty in the neuropathic bladder. Neurourol Urodyn 1995; 14(1): 5-10.]. In this series, we review 51 consecutive patients undergoing the same operation over a 10-year period from 2004 to 2014 in the same single unit. OUTCOME MEASURES: Demographic data were collected to include patient age, condition, and previous treatments. Pre- and post-operative details included sphincter insertions, renal function, continence rates, and complications. RESULTS: Despite an increase in the number of patients seen at the unit, there were considerably fewer cystoplasty procedures performed in the current series (51 vs. 78 in the 1982-1992 series). There were also significantly fewer patients with spina bifida and fewer concomitant sphincter insertions in the latter series (eight patients vs. 52 in the 82/92 series). Nevertheless, similar outcomes are observed between the current and 1982-1992 series, with continence rates of 93.7 and 93.6%, respectively and low numbers of reported adverse events for both retrospective cohorts. CONCLUSIONS: Cystoplasty remains a safe and effective option for the management of neuropathic bladder in a carefully selected group of patients. PMID- 30299217 TI - The impact of canister geometry on chemical biological radiological and nuclear filter performance: A computational fluid dynamics analysis. AB - Steady-state axisymmetric simulations using the Reynolds-Averaged Navier-Stokes equations have been carried out in order to optimize the performance of a Chemical, Biological, Radiological and Nuclear (CBRN) canister filter for its use in a powered air-purifying respirator (PAPR). Alterations have been made to the shape of the canister, the spacing of the rear wall of the canister with regard to the carbon filter, and the bracketing between (i) the particulate filter and the carbon bed and (ii) the carbon bed and the canister wall. The pressure drop across the canister and the residence time distribution at the rear of the carbon bed have been analysed in detail based on an extensive parametric analysis involving the aforementioned variations. It has been demonstrated that the non uniform porosity profile of the carbon bed resulted in alternating regions of high and low velocity close to the canister wall, providing a possible route for breakthrough. Designs, which included a bracket at the rear of the carbon bed, blocked this route and consequently had a longer minimum mean residence time than those, which did not. It has also been shown that the spacing between the carbon bed and the canister rear wall had a large impact on both residence time and pressure drop. In cases where the carbon backed directly onto the canister rear wall flow in the axial direction from the outside wall towards the canister axis resulted in far greater pressure drop and a reduction in minimum mean residence time within the carbon bed. PMID- 30299218 TI - The Ongoing Sodium Controversy - Between PURE and NutriCode. AB - The impact of sodium intake on cardiovascular health has long been a subject of controversial debates. On the one hand, the World Health Organization (WHO) and the American Heart Association (AHA) have argued for a target of 1500-2000 mg of sodium per day (4-5 g sodium chloride daily). On the other hand, this recommendation has been accompanied by a growing body of criticism. Recently, the results of the PURE and the NutriCode study have flared up the "salt controversy". Actually, the results of the PURE study seem to strengthen the position of those who have called into question the AHA and WHO guidelines for daily sodium intake whereas those who recommend a considerable salt reduction believe that the NutriCode study confirm their conviction. In this paper, the results of the PURE and NutriCode study will be discussed and evaluated with regard to practical consequences. PMID- 30299219 TI - Analysis on the risks of severe adverse events in rabies post-exposure prophylaxis and appropriate decision-making procedure. AB - Severe adverse events (AEs) following post-exposure rabies vaccination had been occasionally described in previous studies. Once AEs occurred, immediate medical treatment and appropriate change of vaccine and vaccination schedule were of significance. It was also important and challengeable to determine the relationship among adverse reactions, vaccines residues and laboratory tests for patients, to choose a proper vaccine in resumed vaccination, to avoid the reoccurrence of AEs and to ensure adequate immune response. Here, we present steps about how to cope with AEs by giving an example with a two-year-old girl who was identified as category II exposure to rabies, suffered from anaphylaxis after first dose administration with human diploid rabies vaccine (HDCV) so vaccination was temporarily suspended. Dexamethasone was prescribed to her in anti-allergy therapy. Allergy tests indicated that the patient was not sensitive to allergens and heterologous proteins. Vaccine test report showed that residual kanamycin existed in that batch of vaccines. This reminded us to provide her antibiotic skin sensitivity test which found she was allergic to kanamycin. Thus, we could conclude it was the cause of AEs. Then, 0.5 mL lyophilized Purified Vero Cell Rabies Vaccine (PVRV) without any residues was enrolled in the resumed vaccination. To ensure successful immunization, immunogenicity test was also provided which showed adequate immune response (RVNA >= 0.5 IU/mL) starting from day14. Besides, no further AEs occurred afterward. This study emphasized the importance of in-depth survey, analysis and implied the necessity to scientifically and properly choose the optimal vaccine for patients and appropriately provide treatments if AEs occurred. PMID- 30299220 TI - Achieving high HPV vaccine completion rates in a pediatric clinic population. AB - OBJECTIVE: To evaluate the efficacy of an intervention utilizing patient navigators (PNs) to 1) educate families on human papillomavirus (HPV) vaccination in a clinic setting and 2) provide personalized reminders for follow-up. METHOD: Families with 9-17 year-old children who had no record of completing the HPV vaccination series receiving primary or specialty care in 3 pediatric clinics were approached by PNs between February 1, 2015 and August 31, 2016. Demographic characteristics, visit type, preferred contact method, rates and correlates of completion, and appointments missed were analyzed. In addition, qualitative interviews of 21 providers and PNs assessed their perceptions of the program. RESULTS: 1,391 adolescents were identified out of 2,162 patients approached as unvaccinated or partially vaccinated prior starters; among the unvaccinated, 930 received the 1st dose after being counseled by the PN (66.9%), either immediately or at a follow-up visit soon thereafter. This included 118 siblings of patients who did not have an appointment that day. Of initiators approached between 2/1/2015 and 8/31/2016, 93% (864/930) completed the series by 8/31/2017. No differences in series completion among initiators were observed by gender or race/ethnicity, but older patients (15-17 years old) were less likely to complete than 11-12 year olds. Of the 688 patients identified as prior starters, 85% completed the series through the program. Qualitative interviews demonstrated that providers felt the program addressed major barriers to HPV vaccination. CONCLUSION: Employing PNs dramatically increased HPV vaccine series completion among boys and girls with historically low HPV vaccination rates at pediatric clinics in Texas. Clinic providers felt this program addressed many barriers they observed prior to program implementation. This approach could markedly improve HPV vaccine series completion rates in the US. PMID- 30299221 TI - New ways to get policy into practice. AB - PURPOSE: Health service effectiveness continues to be limited by misaligned objectives between policy makers and frontline clinicians. While capturing the discretion workers inevitably exercise, the concept of "street-level bureaucracy" has tended to artificially separate policy makers and workers. The purpose of this paper is to understand the role of social-organizational context in aligning policy with practice. DESIGN/METHODOLOGY/APPROACH: This mixed-method participatory study focuses on a locally developed tool to implement an Australia wide strategy to engage and respond to mental health services for parents with mental illness. Researchers: completed 69 client file audits; administered 64 staff surveys; conducted 24 interviews and focus groups (64 participants) with staff and a consumer representative; and observed eight staff meetings, in an acute and sub-acute mental health unit. Data were analyzed using content analysis, thematic analysis and descriptive statistics. FINDINGS: Based on successes and shortcomings of the implementation (assessment completed for only 30 percent of clients), a model of integration is presented, distinguishing "assimilist" from "externalist" positions. These depend on the degree to which, and how, the work environment affords clinicians the setting to coordinate efforts to take account of clients' personal and social needs. This was particularly so for allied health clinicians and nurses undertaking sub-acute rehabilitative-transitional work. ORIGINALITY/VALUE: A new conceptualization of street-level bureaucracy is offered. Rather than as disconnected, it is a process of mutual influence among interdependent actors. This positioning can serve as a framework to evaluate how and under what circumstances discretion is appropriate, and to be supported by managers and policy makers to optimize client-defined needs. PMID- 30299222 TI - What's the fuss? Gender and academic leadership. AB - PURPOSE: Women continue to be disproportionately represented in top leadership positions. Leadership development programs typically focus on skills attainment. The purpose of this paper is to explore the perceptions and experiences of academic leaders in order to inform how leadership development programs may more effectively address the gender gap in leadership. DESIGN/METHODOLOGY/APPROACH: A sequential mixed methods study design was used. Participants completed the Leadership Practice Inventory (r)(LPI) survey followed by individual interviews of a subset of participants. The survey results were analyzed and compared by gender using the t-test. Thematic analysis was used to compare themes across and between genders. Quantitative and qualitative findings were integrated in the final analysis. FINDINGS: In total, 65 leaders (38 women; 27 men) (37.7 percent response rate) participated in the survey. There were no significant demographic or statistical differences between women and men on any of the LPI(r) components. Five women and five men were interviewed. Thematic analysis revealed common leadership aspirations and values. Gender differences were noted in leadership attainment, mentorship and the influence of gender on leadership. While the male narratives reflected cognitive awareness of gender inequities, the female narratives also included lived experiences. Male participants focused on the importance of meritocracy whereas the female participants emphasized the gendered social and structural influences on leadership attainment. PRACTICAL IMPLICATIONS: Leadership development programs need go beyond generic "skills building" in order to conceptualize leadership within a gendered social context. This framework will enable critical awareness and tools for developing both women and men's fullest leadership potential. ORIGINALITY/VALUE: This study was conducted in order to better understand how academic health leaders experience the intersection of gender and leadership. The findings contribute to the current literature by providing insight into perceptual gaps that exist at the level of practice between women and men leaders. In doing so, the authors discuss how leadership development programs may play a more effective role in addressing gender equity in leadership. PMID- 30299223 TI - Team based communication and the healthcare communication space. AB - PURPOSE: While previous studies have described structural, process and social aspects of the healthcare communication space there is no overall model of it. Such a model is an essential first step to improving the operationalization and management of healthcare communication. The paper aims to discuss these issues. DESIGN/METHODOLOGY/APPROACH: This paper used a case study approach to study team based communication on a palliative care unit. Non-participant observation, interviews and documents were analyzed using qualitative content analysis. FINDINGS: The analysis developed an overall model of the healthcare communication space that consists of five stages: purpose, practices and workflows, structures, implementation, and the development of common ground to support team-based communication. The authors' findings emphasized that implicit communication remains a predominant means of communication and workflow issues at the individual level are a frequent cause of unnecessary group communication tasks. ORIGINALITY/VALUE: To improve team-based communication we first need to develop protocols that support team communication needs such as loop closing of group communication tasks in order to minimize unnecessary individual communication tasks. We also need to develop common ground at the protocol, document and terminology levels as part of supporting team-based communication. PMID- 30299224 TI - Discursive practice - lean thinking, nurses' responsibilities and the cost to care. AB - PURPOSE: The purpose of this paper is to explore the literature regarding work intensification that is being experienced by nurses, to examine the effects this is having on their capacity to complete care. The authors contend that nurses' inability to provide all the care patients require, has negative implications on their professional responsibility. DESIGN/METHODOLOGY/APPROACH: The authors used institutional ethnography to review the discourse in the literature. This approach supports inquiry through the review of text in order to uncover activities that remain institutionally accepted but unquestioned and hidden. FINDINGS: What the authors found was that the quality and risk management forms an important part of lean thinking, with the organisational culture influencing outcomes; however, the professional cost to nurses has not been fully explored. RESEARCH LIMITATIONS/IMPLICATIONS: The text uncovered inconsistency between what organisations accepted as successful cost savings, and what nurses were experiencing in their attempts to achieve the care in the face of reduced time and human resources. Nurses' attempts at completing care were done at the risk of their own professional accountability. PRACTICAL IMPLICATIONS: Nurses are working in lean and stressful environments and are struggling to complete care within reduced resource allocations. This leads to care rationing, which negatively impacts on nurses' professional practice, and quality of care provision. ORIGINALITY/VALUE: This approach is a departure from the standard qualitative review because the focus is on the textual relationships between what is being advocated by organisations directing cost reduction and what is actioned by the nurses working at the coalface. The discordant standpoints between these two juxtapositions are identified. PMID- 30299225 TI - Darzi Clinical Leadership Fellows: an activity theory perspective. AB - PURPOSE: The purpose of this paper is to review the impact of the clinical leadership programme, in enabling the Darzi fellows to lead change projects in health and care services, and to secure quality healthcare in the NHS beyond the lifetime of the programme. DESIGN/METHODOLOGY/APPROACH: A longitudinal empirical investigation of clinical leaders ( n=80) over an eight-year period was framed through an activity theory (AT)-driven research methodology using a mixed-methods approach. FINDINGS: AT illuminated how change was sustained in the NHS in London through the Darzi Clinical Leadership Fellowship. By any reasonable measurement, this programme excels, with learning and positive behavioural change sustained after the Fellowship across the NHS. Further recognition is needed of the continuing development needs of fellows as they take on more responsible leadership roles in their careers. RESEARCH LIMITATIONS/IMPLICATIONS: Darzi fellows are a hard-to-reach group. The sample represents a response rate of 34 per cent. In total, 77 per cent of respondents emanated from cohorts 5 to 8 programmes. PRACTICAL IMPLICATIONS: The investment in a clinical leadership programme focused on systems leadership for quality generates value for the NHS. SOCIAL IMPLICATIONS: Countless interventions flowed through London's healthcare community and beyond as a result of the Fellowship. This research exposed how Darzi fellows continue to lead innovation for alternative healthcare outcomes. Many proactive fellows employ a suite of learned skills and capabilities to lead systemic change. ORIGINALITY/VALUE: This research is the first known longitudinal clinical leadership development study undertaken. The Darzi programme has created a unique clinical network of mutually supportive, team-centric systems thinkers and doers, with an evidence-based approach to systems change. Many fellows are catalysing sustainable change in the healthcare environment. PMID- 30299226 TI - Stroke rehabilitation and research: consideration of the role of the cortico reticulospinal system. AB - A cerebrovascular accident, otherwise known as stroke, has the potential to damage multiple areas within the brain affecting descending motor control via a multitude of pathways resulting in a wide variety of movement problems. The cortico-reticulospinal system, one of the largest motor systems, is frequently affected, compromising its output, resulting in postural control deficits. The identification of clinically relevant instruments and scales to document and evaluate recovery in post-stroke patients is vital. However, the availability of such measures and scales which take into consideration the role of postural control as an integral component of functional movement performance are scarce. This paper will critically discuss the importance of integrating current neuroscience and motor control knowledge in order to better understand and describe the clinical presentation of persons post-stroke such that the effectiveness of stroke rehabilitation can be appropriately measured. PMID- 30299227 TI - Early predictors of developing problematic spasticity following traumatic spinal cord injury: A prospective cohort study. AB - OBJECTIVE: To identify early predictors and develop reliable, validated prediction models for development of problematic spasticity after traumatic spinal cord injury (SCI). DESIGN: Prospective cohort study of the Rick Hansen Spinal Cord Injury Registry (RHSCIR), retrospective review of inpatient medical charts. SETTING: Quaternary trauma center, rehabilitation center, community settings. PARTICIPANTS: Individuals with traumatic SCI between March 1, 2005, and March 31, 2014, prospectively enrolled in the Vancouver site RHSCIR. INTERVENTIONS: None. MAIN OUTCOME MEASURE: Spasticity limiting function or requiring treatment (problematic spasticity) on the Spinal Cord Injury Health Questionnaire. RESULTS: In 350 patients, variables documented during hospitalization that predicted the development of problematic spasticity up to 5 years post-injury included: initial Glasgow Coma Scale; age at time of injury; admission to rehabilitation center; community discharge anti-spasticity medication prescription, neurological status, Penn Spasm Frequency Scale, and pain interference with quality of life, sleep, activities; greater change in AIS motor scores between admission and discharge. The predictive models had area under the receiver operating characteristic curve of 0.80 (95% CI 0.75, 0.85) in the development set (N = 244) and 0.84 (95% CI 0.74, 0.92) in the validation set (N = 106) for spasticity limiting function and 0.81 (95% CI 0.76, 0.85) in the development set and 0.85 (95% CI 0.77, 0.92) in the validation set for spasticity requiring treatment. CONCLUSIONS: Our prediction models provide an early prognosis of risk of developing problematic spasticity after traumatic SCI, which can be used to improve clinical spasticity management and assist research (e.g. risk stratification in interventional trials). PMID- 30299228 TI - Detecting lenticulostriate artery lesions in patients with acute ischemic stroke using high-resolution MRA at 7 T. AB - Background Recent advances in high-resolution (HR) magnetic resonance angiography (MRA) using ultrahigh-field systems enable direct visualization of the lenticulostriate arteries (LSAs), which had been hardly achieved by conventional MRA. Hence, by using HR-MRA at 7 T, we attempted to assess occlusive changes in the LSAs in patients with LSA territorial infarcts. Methods We prospectively examined 34 consecutive patients with acute ischemic stroke in the LSA territory using a 7 T scanner. We measured the lengths of the relevant LSAs on HR-MRA and the diameters/volume of the infarcts and compared these between the patients with/without occlusive changes in the LSAs. Results On HR-MRA, occlusion of the LSAs was observed in 19 (59%) of 32 patients who were eligible for the analyses. The curved/straight lengths of the LSAs in the patients with LSA occlusion (23.1 31.1/17.8-24.3 mm) were significantly shorter than in those without apparent LSA occlusion (25.8-39.5/24.0-30.4 mm) ( P = 0.027/0.003). The anteroposterior/superoinferior diameters of the infarcts were significantly larger in the occluded-LSA group (14.5-21.4/14.9-22.2 mm) than in the intact-LSA group (10.9-16.8/10.8-16.2 mm) ( P = 0.041/0.011). In addition, the curved lengths of the relevant LSAs showed significant correlations with the superoinferior diameters of the infarcts ( r = 0.38, P = 0.034). Conclusion Occlusive changes in the LSAs were frequently found in patients with acute ischemic stroke within the LSA territory when using HR-MRA at 7 T and were substantially related to superoinferior extension of the infarcts. PMID- 30299230 TI - Statistical analysis plan for evaluating different intensities of blood pressure control in the ENhanced Control of Hypertension And Thrombolysis strokE stuDy. AB - BACKGROUND: The ENhanced Control of Hypertension And Thrombolysis strokE study (ENCHANTED) trial was initiated as a 2 * 2 partial-factorial active-comparison, prospective, randomized, open, blinded endpoint clinical trial to evaluate in thrombolysis-eligible acute ischemic stroke (AIS) patients whether: (1) Arm A - low-dose (0.6 mg/kg body weight) intravenous (iv) alteplase has noninferior efficacy and lower risk of symptomatic intracerebral hemorrhage (sICH) compared with standard-dose (0.9 mg/kg body weight) iv alteplase; and (2) Arm B - early intensive blood pressure (BP) lowering (systolic target 130-140 mmHg) has superior efficacy and lower risk of ICH compared with guideline-recommended BP control (systolic target <180 mmHg). Arm A was completed in 2016; Arm B is now concluding. OBJECTIVE: To outline in detail and make public the predetermined statistical analysis plan (SAP) for the 'BP control' arm of this study. METHODS: All data collected by participating researchers will be reviewed and formally assessed. Information pertaining to the baseline characteristics of patients, their process of care, and the delivery of treatments will be outlined, and for each item, statistically relevant descriptive elements will be described. For the trial outcomes, the most appropriate statistical comparisons to be made between groups are planned and described. RESULTS: A SAP was developed for the results of the BP control arm of this study that is transparent, available to the public, verifiable, and predetermined before completion of data collection. CONCLUSIONS: We have developed a predetermined SAP for the ENCHANTED BP control arm to be followed to avoid analysis bias arising from prior knowledge of the study findings.

PMID- 30299229 TI - High five-year mortality rates of ischemic stroke subtypes: A prospective cohort study in Brazil. AB - BACKGROUND: Studies regarding long-term outcomes of ischemic stroke subtypes are scarce in low- and middle-income countries. We aimed to measure the five-year prognosis of ischemic stroke subtypes in Joinville, Brazil. METHODS: All first ever ischemic strokes that occurred in Joinville in 2010 were followed-up for five years. RESULTS: We included 334 ischemic stroke patients. Over five years, 156 died, 51 had a recurrent stroke, and 128 were free of recurrent stroke. The overall cumulative risk of death was 17% (95% CI, 13% to 22%) at 30 days and 47% (95% CI, 41% to 52%) after five years. Undetermined with incomplete investigation ischemic stroke had a significantly worse survival probability (beta -4.91; 95% CI, -6.31 to -3.50; p < 0.001), followed by cardioembolic ischemic stroke (beta 3.07; 95% CI, -4.32 to -1.83; p < 0.001) and large artery disease ischemic stroke (beta -1.95; 95% CI, -3.30 to -0.60; p = 0.005). The survival probability of undetermined with negative investigation or cryptogenic ischemic stroke did not differ significantly from small artery disease ischemic stroke (beta -1.022; 95% CI, -3.37 to -1.43; p = 0.414). The five-year mortality for small artery disease ischemic stroke was 30% (95% CI, 22% to 39%) and 47% (95% CI, 35% to 60%) for large artery ischemic stroke. The risk of stroke recurrence was 2% in the first year and 5% in the second year. The proportion of disability among survivors in the first month ranged from 8% (95% CI, 3-15) for small artery disease ischemic stroke to 40% (95% CI, 30-52) for cardioembolic ischemic stroke patients. CONCLUSIONS: Cardioembolic and undetermined with incomplete investigation ischemic stroke sub-types have a poor long-term prognosis. An alarming finding was that our patients with both small and large artery ischemic stroke had higher five-year mortality rates compared with subjects from high-income countries. PMID- 30299231 TI - Deep Learning-based Method for Fully Automatic Quantification of Left Ventricle Function from Cine MR Images: A Multivendor, Multicenter Study. AB - Purpose To develop a deep learning-based method for fully automated quantification of left ventricular (LV) function from short-axis cine MR images and to evaluate its performance in a multivendor and multicenter setting. Materials and Methods This retrospective study included cine MRI data sets obtained from three major MRI vendors in four medical centers from 2008 to 2016. Three convolutional neural networks (CNNs) with the U-NET architecture were trained on data sets of increasing variability: (a) a single-vendor, single center, homogeneous cohort of 100 patients (CNN1); (b) a single-vendor, multicenter, heterogeneous cohort of 200 patients (CNN2); and (c) a multivendor, multicenter, heterogeneous cohort of 400 patients (CNN3). All CNNs were tested on an independent multivendor, multicenter data set of 196 patients. CNN performance was evaluated with respect to the manual annotations from three experienced observers in terms of (a) LV detection accuracy, (b) LV segmentation accuracy, and (c) LV functional parameter accuracy. Automatic and manual results were compared with the paired Wilcoxon test, Pearson correlation, and Bland-Altman analysis. Results CNN3 achieved the highest performance on the independent testing data set. The average perpendicular distance compared with manual analysis was 1.1 mm +/- 0.3 for CNN3, compared with 1.5 mm +/- 1.0 for CNN1 (P < .05) and 1.3 mm +/- 0.6 for CNN2 (P < .05). The LV function parameters derived from CNN3 showed a high correlation (r2 >= 0.98) and agreement with those obtained by experts for data sets from different vendors and centers. Conclusion A deep learning-based method trained on a data set with high variability can achieve fully automated and accurate cine MRI analysis on multivendor, multicenter cine MRI data.

AB - Cell therapy has provided unprecedented opportunities for tissue repair and cancer therapy. Imaging tools for in vivo tracking of therapeutic cells have entered the clinic to evaluate therapeutic cell delivery and retention in patients. Thus far, clinical cell tracking studies have been a mere proof of principle of the feasibility of cell detection. This review centers around the main clinical queries associated with cell therapy: Have cells been delivered correctly at the targeted site of injection? Are cells still alive, and, if so, how many? Are cells being rejected by the host, and, if so, how severe is the immune response? For stem cell therapeutics, have cells differentiated into downstream cell lineages? Is there cell proliferation including tumor formation? At present, clinical cell tracking trials have only provided information on immediate cell delivery and short-term cell retention. The next big question is if these cell tracking tools can improve the clinical management of the patients and, if so, by how much, for how many, and for whom; in addition, it must be determined whether tracking therapeutic cells in every patient is needed. To become clinically relevant, it must now be demonstrated how cell tracking techniques can inform patient treatment and affect clinical outcomes. PMID- 30299233 TI - A Predictive Model for Postembolization Syndrome after Transarterial Hepatic Chemoembolization of Hepatocellular Carcinoma. AB - Purpose To develop and validate a predictive model for postembolization syndrome (PES) following transarterial hepatic chemoembolization (TACE) for hepatocellular carcinoma. Materials and Methods In this single-center, retrospective study, 370 patients underwent 513 TACE procedures between October 2014 and September 2016. Seventy percent of the patients were randomly assigned to a training data set and the remaining 30% were assigned to a testing data set. Variables included demographic, laboratory, clinical, and procedural details. PES was defined as pain and/or nausea beyond 6 hours after TACE that required intravenous medication for symptom control. The predictive model was developed by using conditional inference trees and Lasso regression. Results Demographics, laboratory data, performance, tumor characteristics, and procedural details were statistically similar for the training and testing data sets. Overall, 83 of 370 patients (22.4%) after 107 of 513 TACE procedures (20.8%) met the predefined criteria. Factors identified at univariable analysis included large tumor burden (P = .004), drug-eluting embolic TACE (P = .03), doxorubicin dose (P = .003), history of PES (P < .001) and chronic pain (P < .001), of which history of PES, tumor burden, and drug-eluting embolic TACE were identified as the strongest predictors by the multivariable analysis and were used to develop the predictive model. When applied to the testing data set, the model demonstrated an area under the curve of 0.62, sensitivity of 79% (22 of 28), specificity of 44.2% (53 of 120), and a negative predictive value of 90% (53 of 59). Conclusion The model identified history of postembolization syndrome, tumor burden, and drug-eluting embolic chemoembolization as predictors of protracted recovery because of postembolization syndrome.

AB - Purpose To compare common carotid artery (CCA) wall thickness measured manually by using US and semiautomatically by using MRI, and to examine their associations with incident coronary heart disease and stroke. Materials and Methods This prospective study enrolled 698 participants without a history of clinical cardiovascular disease (CVD) from the Multi-Ethnic Study of Atherosclerosis (MESA) from July 2000 to December 2013 (mean age, 63 years; range, 45 to 84 years; same for men and women). All participants provided written informed consent. CCA wall thickness was measured with US as well as both noncontrast proton-density-weighted and intravenous gadolinium-enhanced MRI. Cox proportional hazards models were used to assess the associations between wall thickness measurements by using US and MRI with CVD outcomes. Results The adjusted hazard ratios for coronary heart disease, stroke, and CVD associated with per standard deviation increase in intima-media thickness were 1.10, 1.08, and 1.14, respectively. The corresponding associations for mean wall thickness measured with proton-density-weighted MRI were 1.32, 1.48, and 1.37, and for mean wall thickness measured with gadolinium-enhanced MRI were 1.27, 1.58, and 1.38. When included simultaneously in the same model, MRI wall thickness, but not intima media thickness, remained associated with outcomes. Conclusion For individuals without known cardiovascular disease at baseline, wall thickness measurements by using MRI were more consistently associated with incident cardiovascular disease, particularly stroke, than were intima-media thickness by using US.

PMID- 30299237 TI - Cumulative Radiation Exposures from CT Screening and Surveillance Strategies for von Hippel-Lindau-associated Solid Pancreatic Tumors. AB - Purpose To assess the potential ionizing radiation exposure from CT scans for both screening and surveillance of patients with von Hippel-Lindau (VHL) syndrome. Materials and Methods For this retrospective study, abdomen-pelvic (AP) and chest-abdomen-pelvic (CAP) CT scans were performed with either a three-phase (n = 1242) or a dual-energy virtual noncontrast protocol (VNC; n = 149) in 747 patients with VHL syndrome in the National Institutes of Health Clinical Center between 2009 and 2015 (mean age, 47.6 years +/- 14.6 [standard deviation]; age range, 12-83 years; 320 women [42.8%]). CT scanning parameters for patients with pancreatic neuroendocrine tumors (PNETs; 124 patients and 381 scans) were compared between a tumor diameter-based surveillance protocol and a VHL genotype and tumor diameter-based algorithm (a tailored algorithm) developed by three VHL clinicians. Organ and lifetime radiation doses were estimated by two radiologists and five radiation scientists. Cumulative radiation doses were compared between the PNET surveillance algorithms by analyses of variance, and a two-tailed P value less than .05 indicated statistical significance. Results Median cumulative colon doses for annual CAP and AP CT scans from age 15 to 40 years ranged from 0.34 Gy (5th-95th percentiles, 0.18-0.75; dual-energy VNC CT) to 0.89 Gy (5th 95th percentiles, 0.42-1.0; three-phase CT). For the current PNET surveillance protocol, the cumulative effective radiation dose from age 40 to 65 years was 682 mSv (tumors < 1.2 cm) and 2125 mSv (tumors > 3 cm). The tailored algorithm could halve these doses for patients with initial tumor diameter less than 1.2 cm (P < .001). Conclusion CT screening of patients with von Hippel-Lindau syndrome can lead to substantial radiation exposures, even with dual-energy virtual noncontrast CT. A genome and tumor diameter-based algorithm for pancreatic neuroendocrine tumor surveillance may potentially reduce lifetime radiation exposure.

AB - Large vessel inflammation, although rare, has been increasingly recognised as a complication of granulomatosis with polyangiitis (GPA) in recent years. The presentation is highly variable, ranging from an incidental finding to aortic dissection and rupture. Treatment has predominately consisted of a combination of cyclophosphamide and high dose corticosteroids with surgical intervention when indicated. We present the case of a 34-year-old male diagnosed with GPA after presenting with sinus and eye inflammation and the ensuing investigation revealed large vessel involvement that remarkably improved after 6 months of treatment with the combination of rituximab infusions, methotrexate and corticosteroids. PMID- 30299238 TI - Human papilloma virus genotype distribution and risk factor analysis amongst reproductive-age women in urban Gambia. AB - PURPOSE: Cervical cancer is the most frequently diagnosed female cancer in The Gambia, representing approximately 30 % of cases. In 2014, the quadrivalent human papilloma virus (HPV) vaccine was introduced, which offers protection against HPV genotypes 6, 11, 16 and 18. To evaluate the potential effectiveness of this vaccine, genotype distribution and risk factor analysis were assessed. METHODOLOGY: Endocervical samples (n=232) were collected from women aged 20-49 years residing in urban Gambia. A questionnaire was administered to capture socio demographic and cervical cancer risk factors. HPV detection and genotyping was performed by PCR amplification of the L1 major capsid gene and analysis of sequenced PCR products.Results/Key findings. The prevalence of HPV was 12 % (28/232), and the high-risk (HR) genotype HPV 52 (5/28) was the most prevalent genotype. HR-HPV sequences had high identity (>=90 %) to isolates which originated from America, Europe and Asia but not from Africa. Half (14/28) of participants were co-infected with Ureaplasma urealyticum/parvum, which increases the risk of progression to cervical cancer. Female genital mutilation and the use of hormone contraception for >5 years were identified as potential risk factors for HPV infection. Ethnicity-associated differences were also noted; participants of the Fula ethnic group had a higher prevalence of HR-HPV infection (31.3 %) compared to the Mandinka (18.8 %) and Wollof (12.5 %) groups. CONCLUSION: These data may have a significant public health impact as the HPV quadrivalent vaccine may be of limited value if the circulating non-HPV 16/18 HR-genotypes are responsible for cytological abnormalities of the cervix. PMID- 30299240 TI - Antinuclear antibodies in the general population: positive association with inflammatory and vascular biomarkers but not traditional cardiovascular risk factors. AB - OBJECTIVES: Patients with clinically evident autoimmune disease are at increased risk for premature cardiovascular disease (CVD). Markers of serological autoimmunity such as anti-nuclear antibodies (ANA) are found in approximately 25% of the general population. Yet, the vast majority will not develop clinical autoimmune disease. Serological autoimmunity is a risk factor for CVD death in individuals without autoimmune disease; however, the mechanisms mediating this excess CVD risk have not been elucidated. METHODS: We examined associations of ANA with traditional cardiovascular risk factors, inflammatory mediators, and vascular biomarkers in the Dallas Heart Study - a large, representative multiethnic population-based cohort. Plasma ANA were measured by enzyme linked immunosorbent assay in 3,488 Dallas Heart Study participants aged 30 to 65 years who do not have known rheumatologic disease. Associations of ANA with demographic characteristics, cardiovascular risk factors, and biomarkers were assessed using univariable and multivariable linear regression. RESULTS: Factors independently associated with higher ANA include female sex, African-American race/ethnicity, soluble intracellular adhesion molecule-1, soluble CD40 ligand, chemokine CXCL-2, and Cystatin C (p<0.05 for each). ANA was not associated with traditional cardiovascular risk factors, high sensitivity C-reactive protein, coronary artery calcium scores, or aortic wall thickness. CONCLUSION: ANA are associated with inflammatory mediators and biomarkers of vascular activation, but not with traditional cardiovascular risk factors in a multiethnic population-based cohort. These findings suggest that the cardiovascular risk associated with ANA may involve pathways distinct from traditional risk factors and include dysregulation of endothelial cells and the immune system. PMID- 30299241 TI - Efficacy of tocilizumab monotherapy after response to combined tocilizumab and methotrexate in patients with rheumatoid arthritis: the randomised JUST-ACT study. AB - OBJECTIVES: The aim of the JUST-ACT study was to assess whether the add-on effect of tocilizumab (TCZ) to background methotrexate (MTX) observed in MTX-inadequate responders with active rheumatoid arthritis (RA), would be sustained when MTX is withdrawn. METHODS: A double-blind, parallel-group, phase 3 study in biologic naive RA patients with a disease activity score 28 (DAS28)>3.2 despite MTX which were treated with TCZ+MTX for an initial 16-week period. Patients who at week 16 achieved low disease activity (LDA) (DAS28<=3.2) were randomised to continue with TCZ+MTX or switch to TCZ + placebo (PBO) for an additional 12 weeks. The primary endpoint was the change in DAS28-ESR from the randomisation at week 16 to week 28. Non-inferiority was confirmed if the upper limit of the two-sided 95%CI for the treatment difference between TCZ+MTX and TCZ monotherapy groups was lower than the selected non-inferiority margin of 0.6. RESULTS: 261 patients completed the first 16 weeks of TCZ+MTX treatment and 165 were randomised (83 to TCZ+MTX and 82 to TCZ+PBO). For the primary endpoint, the adjusted treatment difference (95% CI) in mean change of DAS28-ESR was -0.06 (-0.40 to 0.27), and therefore the non-inferiority of switching to TCZ monotherapy versus continuing with TCZ+MTX was demonstrated. In both treatment groups, the percentage of patients in clinical remission from 16 to 28 weeks was similar as were the improvements in disease activity, functional disability and quality of life. CONCLUSIONS: In MTX non-responder patients achieving LDA with TCZ+MTX, switching to TCZ monotherapy is non-inferior to continuing the combination. PMID- 30299242 TI - Inflammation and cardiovascular disease in familial Mediterranean fever. An analysis of hospital admissions for acute cardiovascular event. AB - OBJECTIVES: Patients, suffering from inflammatory disorders, are at an increased risk to develop cardiovascular disease (CVD). Here, we examine whether in familial Mediterranean fever (FMF), a model of inflammatory diseases, inflammation also increases the risk to develop cardiovascular (CV) disease. METHODS: To explore the role of inflammation in the occurrence of CVD in FMF, we identified all FMF patients <=55 years old with CVD, admitted to our center over a 15-year period. Correlates of inflammation, such as severity of FMF and dose of colchicine, as well as the presence of traditional CV risk factors were compared between the FMF patients with CVD (FMF- CVD) and control FMF patients with- out CVD. RESULTS: Twenty-three FMF-CVD and 40 control patients were compared. The severity of FMF, and the dose of colchicine, were similar in the 2 study groups; therefore, not associated with CVD. Compared with FMF patients without CVD, the FMF-CVD group comprised a higher proportion of men (78 vs. 40% p=0.005), and of patients with diabetes (31 vs. 7%, p=0.016) and inflammatory comorbidities such as Behcet's disease (30 vs. 7%, p=0.005). Multivariate analysis revealed that only diabetes mellitus and inflammatory comorbidities were independent factors associated with FMF-CVD. CONCLUSIONS: In FMF patients treated with colchicine, CVD is not associated with FMF-related inflammation. PMID- 30299243 TI - Why are Behcet's disease patients always exhausted? AB - OBJECTIVES: Patients with Behcet's disease (BD) constantly complain of fatigue and many have problems with poor sleep. This ultimately has a major impact on all aspects of normal living. To attempt to understand this, Artificial Intelligence (AI) was used to identify potential biomarkers. These were alpha-melanocyte stimulating hormone (alpha-MSH), vasoactive intestinal peptide (VIP) and some inflammatory cytokines. We assessed the association of fatigue, quality of sleep and disease activity with circulating concentration of alpha-MSH, VIP and inflammatory cytokines. METHODS: There were 127 participants, 97 BD patients, and 30 healthy controls (HC). All completed the Multi-Dimensional Assessment of Fatigue questionnaire (MAF) and the Pittsburgh Sleep Quality Index (PSQI) on the day of their clinical assessment. Enzyme-linked immunosorbent assays (ELISA) were used to evaluate the serum concentrations of alpha-MSH, VIP and cytokines (IL 1beta, IL-6, IL-10, and TNF-alpha). RESULTS: 64% of BD patients experienced high fatigue scores, and 63% had poor quality of sleep. When BD and HC were compared the MAF and PSQI scores as well as the serum concentrations of alpha-MSH, VIP, and IL-6 were significantly higher in BD (p values were: 0.001, 0.001, 0.001, 0.004 and 0.036, respectively). Both alpha-MSH and IL-6 had significant impact on MAF and PSQI. Interestingly, VIP had a significant influence on PSQI and disease activity, but not on MAF. CONCLUSIONS: A better understanding of these complex clinical and biochemical interactions between alpha-MSH, VIP and IL-6 might lead to the development of novel approaches to manage fatigue and sleep disorders as well as disease activity in BD patients. PMID- 30299244 TI - Short-term clinical worsening is a clear predictor for worsening at 2 years in established knee and hip osteoarthritis. AB - OBJECTIVES: Our aim was to estimate the proportion of knee and hip OA patients showing worsening at 2 years, and to examine the additional predictive value of failure of optimised non-surgical treatment during 3 months for worsening at 2 years. METHODS: Data of patients participating in the longitudinal CONTROL-PRO study (patients fulfilling clinical ACR criteria for knee or hip OA) were used. Measurements of pain, functioning and patient global assessments were performed at baseline, 3 months and 2 years. Worsening at 2 years was defined as fulfilling the recently validated clinical worsening criteria for knee and hip OA, or total joint replacement (TJR). Logistic regression was performed with worsening at 2 years as the dependent variable. RESULTS: The 297 included patients were predominantly women (66%) with a mean age of 55 years. At 2 years, 61% showed worsening (knee 59%; hip 71%) and 24% had undergone a TJR (knee 19%; hip 51%). Clinical worsening at 3 months appeared to be a clear independent predictor for worsening at 2 years (OR 2.8 95% CI 1.5-5.2) with a moderate discriminative ability (AUC 0.68 95% CI 0.57-0.70). Similar results were obtained when only TJR at 2 years was used as the outcome measure (OR 4.1 95% CI 2.0-8.4) with good AUC (0.82 95% CI 0.76-0.87). CONCLUSIONS: Our findings suggest that re-assessment of symptoms after optimised non-surgical treatment could be meaningful in clinical decision making for TJR. Furthermore, this information could be used to identify subgroups of patients potentially eligible for novel and advanced treatment options. PMID- 30299245 TI - Epidemiological characteristics of psoriatic arthritis. AB - Psoriatic arthritis (PsA) is a specific form of inflammatory arthritis associated with skin psoriasis. PsA makes part of a heterogeneous group of arthritides called the spondyloarthropathies. Several studies regarding the prevalence and incidence of PsA have been published during the last decades, showing a considerable variation of the disease occurrence among different populations. The purpose of this review is to discuss recent observations of epidemiological features for PsA patients. Thus, the literature was reviewed until May 2018 for studies regarding PsA epidemiology, classification criteria and risk factors for PsA development. Systematic reviews based on the international bibliography, are reporting the prevalence of the disease from 1/100.000 inhabitants in Japan to as high as 420/100.000 inhabitants in Italy. The annual incidence also varies, ranging from 1 to 23/100.000 inhabitants, while the average incidence rate is 6.5 cases/100.000 inhabitants. The random effect pooled PsA prevalence and incidence rates are 133/100.000 and 83/100.000 subjects respectively. Thus, a large heterogeneity between studies is observed. This variability could be explained by a number of factors such as the use of multiple and different classification criteria in the studies. Geographical variations are also observed regarding disease occurrence. Differences were found not only between different continents, but also within the same geographic regions. This could be explained by the different genetic background especially the distribution of the human leucocyte antigens. In addition, other factors such as environmental (infections, climate, sun exposure), dietary habits (fish oil consumption, Mediterranean diet) or life style habits (obesity, smoking), could explain the geographic variability in the prevalence estimates. The implementation of unanimous classification criteria and the conformation by the scientific community could lead to a better understanding of the disease epidemiology. PMID- 30299246 TI - Implication of CXCL5 (epithelial neutrophil-activating peptide 78) in the development of insulin resistance in patients with rheumatoid arthritis. AB - OBJECTIVES: The chemokine molecule CXCL5 (C-X-C motif chemokine ligand 5, also known as epithelial neutrophil activating peptide 78 -ENA78-) constitutes a link between obesity, inflammation and insulin resistance (IR) in the general population. CXCL5 has also been found to play a role in rheumatoid arthritis (RA) pathogenesis. Since chronic inflammation promotes IR and impairs pancreatic beta cell function in RA patients, we assessed the role of CXCL5 in the development of IR in RA. METHODS: Cross-sectional study that encompassed 141 non-diabetic patients with RA. IR assessed by homeostatic model assessment (HOMA2), insulin and C-peptide serum levels and lipid profile, and CXCL5 serum levels were studied. Regression analysis was performed to evaluate how CXCL5 was related to IR, disease activity, and disease characteristics in RA patients. RESULTS: HOMA2 IR indexes showed high values for both IR and beta cell production (%B), and low insulin sensitivity (%S) in patients with RA. C reactive protein (beta coef. 0.2 [95%CI -1.5-1.9], p=0.80) and disease activity through DAS28 (beta coef. 13 [95%CI -14-41], p=0.34) revealed no relation with CXCL5. Other disease characteristics, such as disease duration, serological status, or use of methotrexate or anti-TNF alpha therapies, were not associated with CXCL5 serum levels. While glucocorticoids were related to insulin, C-peptide serum levels, and HOMA2-IR and HOMA2-%B-C peptide, the use of prednisone was not associated with CXCL5 serum levels. Insulin and C peptide serum levels and IR indexes showed strong correlations among each other, but not with CXCL5 (insulin r2=-0.034, p=0.69; C peptide r2=-0.050, p=0.56). CONCLUSIONS: CXCL5 is not related to IR in RA patients. Therefore, the mechanisms leading to IR in patients with RA may be different from those in the general population. PMID- 30299247 TI - Prevalence of sicca syndrome in the Peruvian population. AB - OBJECTIVES: Sjogren's syndrome is a complex and heterogeneous autoimmune disease characterised by ocular and oral dryness (1), which mainly affects the exocrine glands. The objective of this study was to determine the prevalence of sicca syndrome (SS) in the Peruvian population. The age and gender of patients with SS and their national prevalence and in each of the departments were defined. METHODS: Cross-sectional prevalence study. All the people that the Ministry of Health (MINSA) in Peru covered health treatments from January to December 2016 were taken into account. The patients with SS were newly or previously diagnosed with sicca syndrome (Sjogren's) according to the international classification of diseases version 10 (ICD-10) of the World Health Organization (WHO). The prevalence was determined considering the number of cases of SS in the total population registered by the Ministry of Health (MINSA). RESULTS: 1,301 cases of SS were observed in a total population of 15,417,345 people served in 25 territories. The prevalence of SS in this population was 0.0084%, the prevalence rate was 8.4 cases per 100,000 persons (95% CI: 7.99-8.91). The prevalence of SS was higher in the territories of Tacna, Lima, La Libertad, Arequipa, Callao, and Apurimac. CONCLUSIONS: The results of this study show the prevalence of SS in the Peruvian population and serve to strengthen the health strategies of rheumatology, ophthalmology, and oral health to improve the diagnosis, treatment, follow-up of the disease, and the quality of life of patients with SS. PMID- 30299248 TI - Serum calprotectin as a marker of clinical and ultrasound-detected synovitis in early psoriatic and rheumatoid arthritis: results from a cross-sectional retrospective study. AB - OBJECTIVES: We aimed to evaluate the correlation between serum calprotectin and clinical and ultrasonographic (US) variables in early-onset psoriatic arthritis (PsA) and controls with rheumatoid arthritis (RA). METHODS: In a retrospective cross-sectional study, including PsA and matched RA patients, 44 joint counts (TJC, SJC), calprotectin, ESR and CRP were measured. US of wrists and MCPs 1-5 was performed, with grey-scale (GS) and power Doppler (PD) scored 0-3 at each site, summed in a total score. The correlation between calprotectin, clinical and US variables was evaluated by Spearman's coefficient, the predictivity by calprotectin of US by regression. Secondary analyses separating polyarticular PsA and using different US definitions (GS>1, PD>1) were performed. RESULTS: 78 PsA and 78 RA were included (PsA male 32%; mean age 51.7 (13.5)). Calprotectin did not significantly differ in PsA and RA. In PsA, calprotectin correlated with GS score (rho=0.340, p=0.008), PD score (rho=0.292, p=0.023) and the presence of PD (rho=0.263, p=0.042); in RA there were no significant correlations. In polyarticular PsA, a significant correlation between calprotectin and GS (rho=0.369, p=0.019) and PD scores (rho=0.363, p=0.021) was confirmed. In both PsA and RA, calprotectin and CRP significantly correlated, while SJC and TJC did not. In the regression analysis, calprotectin did not predict US variables in PsA. Similar results were achieved in RA. CONCLUSIONS: In early PsA, serum calprotectin correlates with US measures of disease activity. Our results provide preliminary evidence for the application of this biomarker in early PsA. PMID- 30299249 TI - Does the cognitive index of the symptom severity scale (SSS) evaluate cognition? Data from subjective and objective cognitive measures in fibromyalgia. AB - OBJECTIVES: The current provisional diagnostic criteria for the fibromyalgia syndrome (FM) include a cognitive index score (SSS-Cog), which constitutes a part of the Symptom Severity Scale (SSS). The current study aimed at assessing the validity of the cognitive index score, by comparing this subjective measure of cognitive impairment with an objective measure of cognitive functioning, collected through comprehensive computerised cognitive testing and assessment. METHODS: 50 FM patients underwent a computerised cognitive assessment battery, including testing in domains of memory, executive function, attention and information processing speed (NeuroTraxCorp.). Age and education standardised scores were computed. FM symptoms were assessed by the Fibromyalgia Impact Questionnaire (FIQ), Widespread Pain Index (WPI) and Symptom Severity Scale (SSS), a Visual Analog Scale (VAS) of clinical pain and the Beck Depression inventory (BDI-II). RESULTS: The index score for subjective assessment of cognitive decline (SSS-Cog) was not correlated with any of the objective cognitive measures. However, a positive correlation was found between the SSS-Cog and the FIQ, the WPI and the VAS measures, all reflecting subjective overall functional ability. CONCLUSIONS: No significant relationship was found between FM patients' subjective appraisal of cognitive deficit and objective cognitive scores on all computerised subtests. However, subjective appraisal of cognitive impairment was found to be strongly and significantly related to patients' functional ability. Therefore, we suggest reconsidering the definition of this index score (SSS-Cog) and propose developing novel and more accurately defined tools in order to measure cognitive impairment in FM patients, for both diagnostic and epidemiological purposes. PMID- 30299250 TI - Increased interleukin-22 levels in lupus nephritis and its associated with disease severity: a study in both patients and lupus-like mice model. AB - OBJECTIVES: Interleukin-22 (IL-22) has been considered as an inflammatory cytokine. In the present study, we investigated the potential role of IL-22 in lupus nephritis (LN). METHODS: We examined the IL-22 levels of serum and kidney tissue from LN patients and MRL/lpr mice. An intraperitoneal injection of saline, isotype control antibody (IgG), prednisone (3mg/kg/mouse), or anti-IL-22 mAb (5MUg/kg/mouse or 25MUg/kg/mouse) was administered twice a week from 6 to 18 weeks of age. RESULTS: IL-22 levels in both serum and kidney were significantly higher in LN patients as compared with those in healthy controls. The serum and renal levels of IL-22 in MRL/lpr mice were significantly increased over time. After MRL/lpr mice were treated with anti-IL-22 monoclonal antibody (mAb) for 12 weeks, significantly less urine protein and lower serum levels of creatinine and urea nitrogen were found. In addition, less renal injury score and few number of inflammatory cells per glomerulus were observed in MRL/lpr mice treated with anti IL-22 mAb as compared with control groups. CONCLUSIONS: Our results suggest that IL-22 as a pathogenic cytokine might be a potential target for treatment of lupus nephritis. PMID- 30299251 TI - Clinical and genetic characteristics of ankylosing spondylitis patients with peripheral arthritis at disease onset. AB - OBJECTIVES: The aim of this study was to assess the clinical and genetic characteristics associated with the presence of peripheral arthritis (PA) at disease onset in patients with ankylosing spondylitis (AS). METHODS: 456 Spanish AS patients, diagnosed according to the modified New York Criteria, who had at least ten years of follow-up since initial disease onset were selected from the National Spondyloarthropathies Registry (REGISPONSER). 18.9% of AS patients initially presented PA. Clinical variables and 384 single nucleotide polymorphisms (SNPs) distributed in 190 genes were analysed. SNP genotyping was performed using the Illumina GoldenGate genotyping platform. Association tests for allele frequencies and for categorical clinical variables were performed by the chi2 test and with the unpaired t-test for continuous variables. p-values of <0.05 were considered statistically significant. RESULTS: AS patients with PA showed an earlier age of disease onset (p=0.021), longer disease duration (p=0.020) and longer duration of AS symptoms from onset (p=0.034) than AS patients without PA. We found significant associations with the presence of PA at disease onset in 14 SNPs located in 10 genes: HLA-DQB2 (rs2857210 and rs9276615), HLA-DOB (rs2857151, rs2621332 and rs1383261), JAK2 (rs7857730), IL-23R (rs11209008 and rs10489630), CYP1B1 (rs1056836), NELL1 (rs8176786), KL (rs564481), and MEFV (rs224204), IL-2RB (rs743777) and IL-1A (rs1800587). CONCLUSIONS: Both clinical and genetic factors are associated with the presence of PA at disease onset in Spanish AS patients. The results suggest that this subset of AS patients with PA at disease onset might have differentiation factors involved in disease pathogenesis. PMID- 30299252 TI - Association of a polymorphism of the Fcgamma-receptor 2A (FCGR2A) gene with chronic periaortitis. AB - OBJECTIVES: Chronic periaortitis (CP) is an inflammatory disease associated in 20 60% of the cases with IgG4 related disease. Current evidence supports an autoimmune nature for CP. Fc gamma receptors (FcgammaRs) are involved in several immune system activities and are associated with autoimmunity in general. We explored the influence of genetic variants within this region on susceptibility to CP. METHODS: Genotyping of 4 candidate single nucleotide polymorphisms (SNPs) of the FCGR region was performed in CP patients and controls. RESULTS: One hundred and eighty-three cases and 181 controls were included. An association between the SNP rs1801274 of the FCGR2A and CP was detected (OR 1.6, 95%CI 1.18 2.16;corrected p-value, pcorr=0.0085). After stratification of the population according to clinical characteristics, the association was restricted to cases of idiopathic retroperitoneal fibrosis (OR 1.66, 95%CI 1.21-2.29;pcorr=0.028), without involvement of the thoracic aorta (OR 1.77, 95%CI 1.21-2.57;pcorr=0.043), with deep vein thrombosis at onset (OR 3.96, 95%CI 1.81-8.66;pcorr=0.0021) and with normal IgG4 levels (OR 2.67, 95%CI 1.39-5.12;pcorr=0.031). CONCLUSIONS: In the largest candidate gene approach study performed so far in CP, we demonstrated an association for CP with a gene hallmark of autoimmunity. The association appears restricted to typical cases of CP without increase of IgG4 levels. PMID- 30299253 TI - Mitochondria reorganization upon proliferation arrest predicts individual yeast cell fate. AB - Most cells spend the majority of their life in a non-proliferating state. When proliferation cessation is irreversible, cells are senescent. By contrast, if the arrest is only temporary, cells are defined as quiescent. These cellular states are hardly distinguishable without triggering proliferation resumption, hampering thus the study of quiescent cells properties. Here we show that quiescent and senescent yeast cells are recognizable based on their mitochondrial network morphology. Indeed, while quiescent yeast cells display numerous small vesicular mitochondria, senescent cells exhibit few globular mitochondria. This allowed us to reconsider at the individual-cell level, properties previously attributed to quiescent cells using population-based approaches. We demonstrate that cell's propensity to enter quiescence is not influenced by replicative age, volume or density. Overall, our findings reveal that quiescent cells are not all identical but that their ability to survive is significantly improved when they exhibit the specific reorganization of several cellular machineries. PMID- 30299254 TI - Range, routing and kinetics of rod signaling in primate retina. AB - Stimulus- or context-dependent routing of neural signals through parallel pathways can permit flexible processing of diverse inputs. For example, work in mouse shows that rod photoreceptor signals are routed through several retinal pathways, each specialized for different light levels. This light-level-dependent routing of rod signals has been invoked to explain several human perceptual results, but it has not been tested in primate retina. Here, we show, surprisingly, that rod signals traverse the primate retina almost exclusively through a single pathway - the dedicated rod bipolar pathway. Identical experiments in mouse and primate reveal substantial differences in how rod signals traverse the retina. These results require reevaluating human perceptual results in terms of flexible computation within this single pathway. This includes a prominent speeding of rod signals with light level - which we show is inherited directly from the rod photoreceptors themselves rather than from different pathways with distinct kinetics. PMID- 30299255 TI - The DWORF micropeptide enhances contractility and prevents heart failure in a mouse model of dilated cardiomyopathy. AB - Calcium (Ca2+) dysregulation is a hallmark of heart failure and is characterized by impaired Ca2+ sequestration into the sarcoplasmic reticulum (SR) by the SR Ca2+-ATPase (SERCA). We recently discovered a micropeptide named DWORF (DWarf Open Reading Frame) that enhances SERCA activity by displacing phospholamban (PLN), a potent SERCA inhibitor. Here we show that DWORF has a higher apparent binding affinity for SERCA than PLN and that DWORF overexpression mitigates the contractile dysfunction associated with PLN overexpression, substantiating its role as a potent activator of SERCA. Additionally, using a well-characterized mouse model of dilated cardiomyopathy (DCM) due to genetic deletion of the muscle specific LIM domain protein (MLP), we show that DWORF overexpression restores cardiac function and prevents the pathological remodeling and Ca2+ dysregulation classically exhibited by MLP knockout mice. Our results establish DWORF as a potent activator of SERCA within the heart and as an attractive candidate for a heart failure therapeutic. PMID- 30299257 TI - Smoking-induced changes in leptin serum levels and c/EBPalpha-related methylation status of the leptin core promotor during smoking cessation. AB - Previous studies have provided evidence of an association between serum leptin levels and smoking as well as craving during smoking cessation. As promoter methylation also regulates leptin expression, we investigated the leptin gene promoter region of smokers before and after smoking cessation. Since leptin's core promoter region contains an essential c/EBPalpha transcription binding site, we narrowed our investigation to C-300 (-300 base pairs from the transcription start site) of that binding site. Female smokers showed hypermethylation of C-300 compared to non-smokers. Global methylation status is associated with higher craving and the degree of dependence in female smokers. Serum leptin levels in female smokers were significantly higher than in non-smokers. These findings support previous results and, for the first time, point to a pathophysiological role of c/EBPalpha-related C-300 methylation in tobacco dependence. PMID- 30299258 TI - Raloxifene as a treatment for cognition in women with schizophrenia: the influence of menopause status. AB - Cognitive impairments cause significant functional issues for people with schizophrenia, often emerging before the onset of hallucinations, delusions and other psychosis symptoms. Current pharmacological treatments do not target cognitive dysfunction. Several lines of evidence support the beneficial effects of estrogens on cognition. Raloxifene hydrochloride, a selective estrogen receptor modulator, has been associated with cognitive improvements in healthy postmenopausal women and in schizophrenia, although findings are inconsistent. Using pooled data from two clinical trials, the aim of the current study was to compare the efficacy of 120 mg/day adjunctive raloxifene to placebo for 12 weeks on cognitive performance in women with schizophrenia who were stratified by menopause status (pre-menopausal; peri-menopausal or post-menopausal). A total of sixty-nine participants with a diagnosis of schizophrenia or schizoaffective disorder were included. Cognition was assessed at baseline and study end using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Results indicated that after stratifying for menopause status (strata) and adjusting for endogenous hormone levels (estrogen, progesterone, follicle stimulating hormone and luteinising hormone), semantic fluency, picture naming and list recognition change from baseline scores for the raloxifene group differed significantly from the placebo group. The findings from the current study highlight the importance of considering menopause status when interpreting the effects of hormonal treatments. PMID- 30299256 TI - Transition between fermentation and respiration determines history-dependent behavior in fluctuating carbon sources. AB - Cells constantly adapt to environmental fluctuations. These physiological changes require time and therefore cause a lag phase during which the cells do not function optimally. Interestingly, past exposure to an environmental condition can shorten the time needed to adapt when the condition re-occurs, even in daughter cells that never directly encountered the initial condition. Here, we use the molecular toolbox of Saccharomyces cerevisiae to systematically unravel the molecular mechanism underlying such history-dependent behavior in transitions between glucose and maltose. In contrast to previous hypotheses, the behavior does not depend on persistence of proteins involved in metabolism of a specific sugar. Instead, presence of glucose induces a gradual decline in the cells' ability to activate respiration, which is needed to metabolize alternative carbon sources. These results reveal how trans-generational transitions in central carbon metabolism generate history-dependent behavior in yeast, and provide a mechanistic framework for similar phenomena in other cell types. PMID- 30299259 TI - Falling in love is associated with immune system gene regulation. AB - Although falling in love is one of the most important and psychologically potent events in human life, the somatic implications of new romantic love remain poorly understood. Psychological, immunological, and reproductive perspectives offer competing predictions of the specific transcriptional regulatory shifts that might accompany the experience of falling in love. To characterize the impact of romantic love on human genome function, we conducted genome-wide transcriptome profiling of 115 circulating immune cell samples collected from 47 young women over the course of a 2-year longitudinal study. Analyses revealed a selective alteration in immune cell gene regulation characterized by up-regulation of Type I interferon response genes associated with CD1C+/BDCA-1+ dendritic cells (DCs) and CLEC4C+/BDCA-2+ DCs, and a reciprocal down-regulation of alpha-defensin related transcripts associated with neutrophil granulocytes. These effects emerged above and beyond the effects of changes in illness, perceived social isolation, and sexual contact. These findings are consistent with a selective up regulation of innate immune responses to viral infections (e.g., Type I interferons and DC) and with DC facilitation of sexual reproduction, and provide insight into the immunoregulatory correlates of one of the keystone experiences in human life. PMID- 30299260 TI - Ciliary neurotrophic factor is a key sex-specific regulator of depressive-like behavior in mice. AB - Ciliary neurotrophic factor (CNTF) is produced by astrocytes and promotes neurogenesis and neuroprotection. Little is known about the role of CNTF in affective behavior. We investigated whether CNTF affects depressive- and anxiety like behavior in adult mice as tested in the forced swim, sucrose preference and elevated-T maze tests. Female wild type CNTF+/+ mice more readily developed behavioral despair with increased immobility time and decreased latency to immobility in the forced swim test than male CNTF+/+ littermates. The lack of CNTF in CNTF-/- mice had an opposite effect on depressive-like behavior in female mice (reduced immobility time and increased sucrose preference) vs. male mice (increased immobility time). Female wildtype mice expressed more CNTF in the amygdala than male mice. Ovariectomy increased CNTF expression, as well as immobility time, which was significantly reduced in CNTF-/- mice, suggesting that CNTF mediates overiectomy-induced immobility time, possibly in the amygdala. Progesterone but not 17-beta estradiol inhibited CNTF expression in cultured C6 astroglioma cells. Progesterone treatment also reduced CNTF expression in the amygdala and decreased immobility time in female CNTF+/+ but not in CNTF-/- mice. Castration did not alter CNTF expression in males nor their behavior. Lastly, there were no effects of CNTF on the elevated T-maze, a behavioral test of anxiety, suggesting that a different mechanism may underlie anxiety-like behavior. This study reveals a novel CNTF-mediated mechanism in stress-induced depressive-like behavior and points to opportunities for sex-specific treatments for depression, e.g. progesterone in females and CNTF-stimulating drugs in males. PMID- 30299261 TI - Effectiveness of Percutaneous Intradiscal Decompression Therapy in Thoracic Disc Herniation. AB - AIMS: Although there have been many studies about lomber and cervical ablation procedures, very few studies have been performed on the thoracic region. This is a study to evaluate the clinical results of percutaneous disc decompression device in patients with radicular symptoms and/or dorsal pain due to thoracic disc herniation. METHODS: Eleven patients with thoracic disc herniation and/or degenerative discs (all in T10-T11, or T11-T12 levels) who did not respond to conservative treatments were undergo ablation and compression procedure. Pain and radicular symptoms consistent with the thoracolumbar region were confirmed via abnormal magnetic resonans image findings after detailed anamnesis and physical examination. All patients were evaluated before and 1, 3, 6 and 12 months after treatment using the visual analoge scale score. The Patient Satisfaction Scale was used to evaluate the level of patient satisfaction at the end of the treatment at 12 months. RESULTS: Median visual analoge scale score was 7.00+/ 0.45 points before treatment, and 2.73+/-0.65 points at 12 month post-procedure were statistically significant (p<0.001). The results of pairwise comparisons using the Bonferroni Corrected Wilcoxon Signed-Rank test showed that there were statistically significant differences. The mean visual analoge scale score at the beginning (7.00+/-0.45) was significantly higher than the mean score at the other months Postoperative improvement was significant with a 99% confidence interval. No complications that may cause permanent damage occured. CONCLUSION: Our results suggest that the percutaneous disc decompression is an effective and safe procedure for the treatment of pain caused by low thoracic intervertebral disc disease which did not respond to conservative treatments. PMID- 30299262 TI - Results of an internal audit on the survival of patients with uterine sarcoma. AB - OBJECTIVE: In the last 5 years there has been a lot of discussion about the surgical procedure for uterine fibroids and essentially also uterine sarcoma. Still there exist no reliable presurgical diagnostic tool to differentiate between benign fibroids and uterine sarcomas. The aim of this study was to confirm the suspected an association between intraoperative spread of tumor by morcellation and impaired outcome in sarcoma patients. MATERIAL AND METHODS: After local ethics commission positively reviewed the study protocol the oncological database of our university hospital was retrospectively reviewed for patients with uterine sarcomas over a time period of 13 years (2002-2015). Data was extracted from the medical files and survival information was collected by contacting patient's general practitioners if last follow-up-status was older than 6 months. For the analysis patients were split into two groups with either intrasurgical morcellation (M+) or no morcellation (M-) regarding information provided by the surgical report. RESULTS: Data on 57 uterine sarcoma patients was available for further analysis. The median age was 63years with a BMI of 27 kg/m2. The sarcoma subtypes were 25 leiomyosarcoma (LMS), 19 carcinosarcoma (KS), 9 endometriod stroma sarcoma (ESS), 3 adenosarcoma (AS) and one case without further differentiation. In the majority, no morcellation was done (44 patients in M- group) and 51 patients received open surgery (3 laparoscopic, 1 vaginal and 2 incomplete surgeries). Median time of follow-up was 31 months. The disease free survival was 50.5 months and the cox regressions analysis showed a hazard ratio of 3.06 (no significant difference between the two subgroups (p=0.079; 95%-KI: 0.9 - 10.6)). The overall survival was found to be 62.2 months and the cox regression analysis showed a hazard ratio of 3.216 with statistical significantdifference between the two subgroups (p=0.013; 95%-KI: 1.3 - 8.1). CONCLUSION: Despite the efforts to find a pre-surgical diagnostic tool, the clinical situation remains unsatisfactory. Overall sarcoma prevalence is low during the last 13 years at our university center, but morcellation occurred in a relevant portion of patients (13 out of 57). If a sarcoma is suspected or diagnosed the en-bloc resection of the uterus can prolong the survival. Thus, morcellation of the uterus and not the surgical technique (en-bloc resection) is the prognostic factor and should be avoided in any suspicious case. PMID- 30299263 TI - Selective fetal reduction in monochorionic twins: Preliminary experience. AB - OBJECTIVE: In complicated mono-chorionic twin pregnancies, vaso-occlusive techniques like bipolar cord coagulation (BPCC), radiofrequency ablation (RFA), interstitial laser ablation (ILA) of cord and fetoscopy guided cord coagulation with lasers are the methods proposed for selective fetal reduction. This study brings forth preliminary data of selective fetal reduction procedures at a tertiary care center in India. MATERIAL AND METHODS: This was a prospective observational study of 31 patients with complicated mono-chorionic twin pregnancies. Methods used were ILA, RFA and BPCC. Outcome measures included overall co-twin survival after selective feticide, survival rates with each method, miscarriage (defined as all fetal loss before 24 weeks), early fetal death (<24 hours after procedure) and late fetal death (>24hrs after the procedure) of co-twin. RESULTS: Technical success was achieved in 30/31(96.8%) of pregnancies. Over all take home baby rate was 63.3%. Live birth rates were 50%, 71.4% and 75%with ILA, RFA and BPCC respectively. CONCLUSION: Data from initial cases of selective fetal reduction in complicated mono-chorionic twins suggests that these procedures are feasible but are associated with high adverse perinatal outcome. PMID- 30299264 TI - Oocyte Donors' Awareness on Donation Procedure and Risks: A Call for Developing Guidelines for Health Tourism in Oocyte Donation Programmes AB - Objective: In the recent years, oocyte donation programmes have widely spread worldwide becoming the drive of health tourism. In some countries the donation programmes are tightly regulated; whereas in some, the guidelines or regulations are not well defined. The aim of this study was to evaluate the donors' awareness of the donation programmes and the ethical consequences in enrolling these programmes. Material and Methods: A detailed questionnaire-based survey was conducted to evaluate the donors' main drive to get involved in the donation programme and the donor's knowledge and awareness of risk factors. Results: Majority of the donors (70%) were undergoing donation programmes for financial gains through compensation. The donors were especially not aware of the long-term medical risks and the possibility of identity exposure through genetic screening. Conclusion: The health professionals have the main duty to counsel the donors about the basic procedures and any possible problems they may face during the donation programmes. Reimbursement of oocyte donors is a slippery slope path in oocyte donation programmes. High compensation may make women to think that donation is a profession without considering possible risks. Furthermore, with the wider use of direct-toconsumer genetic testing, genetic anonymity may be at risk, thus the donors have to be counselled properly. Therefore, in this era of health tourism, it is crucial to set up well-defined counselling bodies in all oocyte donation centres and enable the donors to make an informed choice in becoming oocyte donors. PMID- 30299266 TI - Outcomes in Fournier's Gangrene Using Skin and Soft Tissue Sparing Flap Preservation Surgery for Wound Closure: An Alternative Approach to Wide Radical Debridement. AB - INTRODUCTION: Fournier's gangrene (FG) remains a forbidding necrotizing soft tissue infection (NSTI) that necessitates early recognition, prompt surgical excision, and goal-directed antibiotic therapy. Traditionally, surgical management has included wide radical excision for sepsis control, but this management often leaves large, morbid wounds that require complex wound coverage, prolonged hospitalizations, and/or delayed healing. OBJECTIVE: The purpose of this case series is to report the outcomes of FG using a surrogate approach of concurrent debridement of spared skin and soft tissue, negative pressure wound therapy (NPWT), and serial delayed primary closure (DPC). MATERIALS AND METHODS: A retrospective review of 17 consecutive patients with FG treated with concurrent skin and soft tissue sparing surgery, NPWT, and serial DPC at Miami Valley Hospital Regional Adult Burn and Wound Center (Dayton, OH) between 2008 and 2018 was conducted. Patients were included if the following were noted: clinical suspicion of FG based on genital and perineal cellulitis, fever, leukocytosis, and confirmation of tissue necrosis upon surgical exploration. Patients not treated with skin sparing surgical debridement or wounds with an inability to maintain a NPWT dressing seal were excluded. RESULTS: The mean number of total surgeries including simultaneous debridement and reconstruction was 5.5. The average intensive care unit and hospital length of stay was 3.2 and 18.9 days, respectively. The average number of days from initial consult to wound closure was 24.3. The need for colostomy and skin grafts were nearly eliminated with this surrogate approach. Using this reproducible technique, DPC was achieved in 100% of patients. Only 11.8% (2/17) required split-thickness skin grafting as part of wound closure. The majority (9/17; 52.9%) were partially managed as an outpatient during wound closure. During staged DPC, the mean number of outpatient management days was 16.0. There were no mortalities in this series of patients. CONCLUSIONS: To the best of the authors' knowledge, this is the largest case series reported in the literature using skin and soft tissue sparing surgery for wound closure of a FG NSTI. PMID- 30299267 TI - Unusual Presentation of Deep Tissue Injuries: A Case Series. AB - Deep tissue injuries (DTIs) are the manifestation of multiple layers of tissue necrosis and are often secondary to chronic mechanical stress to an area of bony prominence. The prevalence of these injuries among the chronically ill and patients in long-term care require a strong understanding of their etiology and a highly sensitive identification algorithm. Although the National Pressure Ulcer Advisory Panel (NPUAP) has released new guidelines with accurate descriptions as to how these injuries present, there is a significant segment of patients that present atypically and, as such, the treatment plan and prognosis are difficult to predict based on physical presentation, which can lead to either delays in necessarily aggressive care or conversely an overzealous treatment plan in hopes of addressing a pathology that may be self-limiting. Three cases of patients with a DTI, in which the initial presentation was not typical (ie, as described by the current NPUAP staging system) and not an accurate diagnostic predictor of prognosis, are presented. These differences, their course of treatment, and a more comprehensive diagnostic approach will be discussed in the hopes of more accurately identifying these injuries with a focus on prediction of disease trajectory. PMID- 30299265 TI - The effect of nutrient supplementation in the management of polycystic ovary syndrome-associated metabolic dysfunctions: A critical review AB - Polycystic ovary syndrome (PCOS) is complex heterogeneous disorder that has several aspects in terms of pathology such as metabolic, endocrine, reproductive, and psychological. However, the etiology of PCOS remains poorly understood. Several studies suggest that insulin resistance and hyperandrogenism play a central role in the progression of PCOS pathophysiology. Therefore, common treatment strategies of PCOS are based on lifestyle modification, which include exercise, diet, and nutrient supplementation therapy. Recent studies have recommended some nutrients such as vitamins, minerals, and vitamin-like nutrients for the therapy of PCOS because each has at least one functional property in PCOS induced pathways. Therefore, it is claimed that the cause of PCOS could be vitamin or mineral deficiency. This review aims to provide a critical literature survey on nutritional supplementation for the treatment of PCOS-associated endocrine and metabolic dysfunctions and discuss the role of nutrients in the management of PCOS in view of the clinical trials and experimental studies. PMID- 30299268 TI - The fasting blood glucose and long non-coding RNA SNHG8 predict poor prognosis in patients with gastric carcinoma after radical gastrectomy. AB - This prospective study sought to evaluate the prediction of fasting blood glucose and long non-coding RNA (lncRNA) SNHG8 for the risk of gastric carcinoma mortality. A total of 217 gastric carcinoma patients underwent radical gastrectomy were included during 2012-16. The final follow-up was finished in January 2017. The aggregate hazard ratio(HR) demonstrated that poor prognosis of gastric carcinoma was associated with fasting blood glucose (HR= 1.29, P=0.037), SNHG8 expression(HR = 1.10, P= 0.009), positive distant metastasis(HR = 2.99, P= 0.020), EBV positive (HR = 3.40, P=0.002), and tumor size more than 5.0 cm (HR = 3.36, P= 0.005). In survival analysis, elevated fasting blood glucose (P =0.007) and high SNHG8 expression (P =0.007) were significantly associated with shorter survival times in gastric cancer. Significant multiplicative interaction was shown between fasting blood glucose and SNHG8 expression (chi-squared=7.81, Pmultiplicative =0.005), without statistical additive interaction. Fasting blood glucose and SNHG8 expression could predict poor prognosis after radical gastrectomy. LncRNA SNHG8 could be applied as a novel epigenetic molecular target in gastric carcinoma. PMID- 30299270 TI - Renin-Angiotensin Inhibition and Outcomes in Nursing Home Residents With Heart Failure. AB - BACKGROUND: Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEIs-ARBs) improve outcomes in heart failure (HF). Less is known about this association in nursing home (NH) residents. METHODS: Of the 8024 hospitalized HF patients, 542 were NH residents, of whom 250 received ACEIs-ARBs. We assembled a propensity score-matched cohort of 157 pairs of NH residents receiving and not receiving ACEIs-ARBs balanced on 29 baseline characteristics (mean age, 83 years, 74% women, 17% African American), in which we estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for outcomes associated with ACEI-ARB use. We then checked for interaction in a matched cohort of 5130 patients (378 were NH residents) assembled from the 8024 patients. RESULTS: Among 314 matched NH residents, HRs (95% CIs) for 30-day all-cause readmission, HF readmission, and all-cause mortality were 0.78 (0.47-1.28), 0.68 (0.29-1.60), and 1.26 (0.70-2.27), respectively. Respective HRs (95% CIs) at 1 year were 0.76 (0.56-1.02), 0.68 (0.42-1.09), and 1.04 (0.78-1.38). Among 5130 matched patients, ACEI-ARB use was associated with a significantly lower risk of all outcomes at both times, with no significant interactions, except for 1-year mortality, which was only significant in the non-NH subgroup (P for interaction, 0.026). CONCLUSIONS: We found no evidence that the use of ACEIs or ARBs is associated with improved outcomes in patients with HF in the NH setting. However, we also found no evidence that this association is different in NH residents with HF versus non-NH patients with HF. Future larger studies are needed to demonstrate effectiveness of these drugs in the NH setting. PMID- 30299269 TI - A high glucose diet induces autophagy in a HLH-30/TFEB-dependent manner and impairs the normal lifespan of C. elegans. AB - A high-glucose diet (HGD) is associated with the development of metabolic diseases that decrease life expectancy, including obesity and type-2 diabetes (T2D); however, the mechanism through which a HGD does so is still unclear. Autophagy, an evolutionarily conserved mechanism, has been shown to promote both cell and organismal survival. The goal of this study was to determine whether exposure of Caenorhabditis elegans to a HGD affects autophagy and thus contributes to the observed lifespan reduction under a HGD. Unexpectedly, nematodes exposed to a HGD showed increased autophagic flux via an HLH-30/TFEB dependent mechanism because animals with loss of HLH-30/TFEB, even those with high glucose exposure, had an extended lifespan, suggesting that HLH-30/TFEB might have detrimental effects on longevity through autophagy under this stress condition. Interestingly, pharmacological treatment with okadaic acid, an inhibitor of the PP2A and PP1 protein phosphatases, blocked HLH-30 nuclear translocation, but not TAX-6/calcineurin suppression by RNAi, during glucose exposure. Together, our data support the suggested dual role of HLH-30/TFEB and autophagy, which, depending on the cellular context, may promote either organismal survival or death.

PMID- 30299271 TI - Antithrombotic Therapy and Outcomes of Patients With New-Onset Transient Atrial Fibrillation After ST-Segment Elevation Myocardial Infarction. AB - BACKGROUND: Atrial fibrillation (AF) is a common complication of ST-segment elevation myocardial infarction (STEMI), and AF might require anticoagulant treatment in some conditions. STUDY QUESTION: There are no clear recommendations about vitamin K antagonist (VKA) use in patients with STEMI who complicated with new-onset transient AF. In this study, we examined the association of concomitant use of VKA and dual antiplatelet therapy (DAPT) with clinical outcomes of this patient population. STUDY DESIGN: A total of 4086 patients with STEMI who underwent primary percutaneous coronary intervention retrospectively investigated. Among these patients, a total of 286 patients who developed new onset transient AF during hospitalization were enrolled. VKA group consisted of 116 patients treated with warfarin, aspirin, and clopidogrel, and DAPT group consisted of 170 patients treated with aspirin and clopidogrel. MEASURES AND OUTCOMES: One-year mortality, ischemic stroke, major, and minor bleeding were determined as clinical outcomes. RESULTS: Although VKA group had proportionally lower mortality (17.2% vs. 20.0%) and ischemic stroke (7.8% vs. 11.8%) compared with DAPT group, the differences did not reach to statistical significance, whereas the 1-year major bleeding had higher rates at VKA group and that had 3.5 times higher major bleeding than DAPT group. This relationship was persisted after multivariable analysis (hazard ratio = 3.37, 95% CI, 1.76-10.04, P = 0.012). CONCLUSIONS: There is not a widely accepted treatment algorithm in patients with STEMI who complicated with new-onset AF in clinical guidelines. The current study indicated that transient form of new-onset AF might not require long-term VKA. Besides, addition of VKA to DAPT therapy may increase the rates of major and minor bleeding.

AB - INTRODUCTION: Prior studies have reported higher health care utilization (HCU) leading up to diagnosis of the Alzheimer disease and related dementia (ADRD), but none have assessed variation in HCU by ADRD subtype or examined disease-specific HCU. The objectives of this study were to identify ADRD subtypes and: (1) characterize all-cause and (2) disease-specific HCU during the 3 years preceding diagnosis, and (3) determine if HCU varied by ADRD subtype. METHODS: We used data from the OptumLabs Data Warehouse 2008 to 2014 to identify ADRD subtypes (total N=36,838) using an algorithm based on temporal sequencing of diagnoses and provider type. Annual counts of all-cause and disease-specific HCU in each of the 3 years preceding ADRD diagnosis were regressed on ADRD subtypes with mild cognitive impairment (MCI) as the reference group, year, and other variables. RESULTS: HCU increased over time, was highest in the outpatient setting, and varied by ADRD subtype. Compared with MCI, highest HCU was observed in vascular and nonspecific dementia. Compared with MCI, most subtypes had elevated disease specific HCU. DISCUSSION: Variation in HCU by ADRD subtype points to different pathways to diagnosis and patterns of use. PMID- 30299277 TI - Attenuation of glutamatergic and nitrergic system contributes to the antidepressant-like effect induced by capsazepine in the forced swimming test. AB - The transient receptor potential vanilloid 1 (TRPV1) can modulate stress-related behaviours, thus representing an interesting target for new antidepressant drugs. TRPV1 can trigger glutamate release and nitric oxide synthesis in the brain, mechanisms also involved in the neurobiology of depression. However, it is not known if these mechanisms are involved in TRPV1-induced behavioural effects. Therefore, the aim of this study was to verify if the antidepressant-like effect induced by a TRPV1 antagonist in mice submitted to the forced swimming test (FST) would be facilitated by combined treatment with neuronal nitric oxide synthase (nNOS) inhibition and N-methyl-D-aspartate (NMDA) blockade. Male Swiss mice were given (intracerebroventricular) injections of capsazepine (CPZ) (TRPV1 antagonist - 0.05/0.1/0.3/0.6 nmol/ul), and AP7 (NMDA antagonist - 1/3/10 nmol/ul) or N propyl-L-arginine (NPA, nNOS inhibitor - 0.001/0.01/0.1 nmol/ul), and 10 min later, submitted to an open field test, and immediately afterwards, to the FST. An additional group received coadministration of CPZ and AP7 or CPZ and NPA, in subeffective doses. The results demonstrated that CPZ (0.1 nmol/ul), AP7 (3 nmol/ul) and NPA (0.01/0.1 nmol/ul) induced antidepressant-like effects. Moreover, coadministration of subeffective doses of CPZ and AP7 or CPZ and NPA induced significant antidepressant-like effects. Altogether, the data indicate that blockade of TRPV1 receptors by CPZ induces antidepressant-like effects and that both nNOS inhibition and NMDA blockade facilitate CPZ effects in the FST. PMID- 30299278 TI - Is Self-Reported Knee Stability Associated With Symptoms, Function, and Quality of Life in People With Knee Osteoarthritis After Anterior Cruciate Ligament Reconstruction? AB - OBJECTIVE: This study aimed to investigate the association of self-reported knee stability with symptoms, function, and quality of life in individuals with knee osteoarthritis after anterior cruciate ligament reconstruction (ACLR). SETTING: Cross-sectional. PARTICIPANTS: Twenty-eight individuals with knee osteoarthritis, 5 to 12 years after ACLR. MAIN OUTCOME MEASURES: Self-reported knee stability was assessed using visual analogue scales (VAS) during hop for distance (HD), side-to side hop (SSH), and one-leg rise (OLR). Symptoms [Knee Injury and Osteoarthritis Outcome Score (KOOS) pain, Anterior Knee Pain Scale (AKPS), and International Knee Documentation Committee form], self-reported function (KOOS-sport/rec), performance-based function (hopping and OLR), and quality of life (KOOS-QOL) were assessed. K-means clustering categorized individuals into low (n = 8) and high self-reported knee stability (n = 20) groups based on participants' VAS scores during functional tasks. RESULTS: The low self-reported knee stability group had worse knee symptoms than the high self-reported knee stability group [KOOS-pain: mean difference -17 (95% confidence interval, -28 to -5); AKPS: -10 (-20 to -1)], and worse self-reported function [KOOS-sport/rec: -33 (-48 to -18)] and performance-based function [HD: -28 (-53 to -3); SSH: -10 (-20 to -1), OLR: -18 ( 32 to -50)]. CONCLUSION: Low self-reported stability is associated with worse symptoms, and worse self-reported and performance-based function. Further research is required to determine the causation relation of self-reported knee stability to knee symptoms and function in individuals with knee osteoarthritis after ACLR. PMID- 30299279 TI - Surgical Management of Placenta Accreta Spectrum. AB - This is a discussion of the standard surgical treatment of placenta accreta spectrum disorders including preoperative considerations, diagnostic imaging, surgical steps for cesarean hysterectomy, and postoperative management. PMID- 30299280 TI - Pathophysiology of Placenta Accreta Spectrum Disorders: A Review of Current Findings. AB - Current findings continue to support the concept of a biologically defective decidua rather than a primarily abnormally invasive trophoblast. Prior cesarean sections increase the risk of placenta previa and both adherent and invasive placenta accreta, suggesting that the endometrial/decidual defect following the iatrogenic creation of a uterine myometrium scar has an adverse effect on early implantation. Preferential attachment of the blastocyst to scar tissue facilitates abnormally deep invasion of trophoblastic cells and interactions with the radial and arcuate arteries. Subsequent high velocity maternal arterial inflow into the placenta creates large lacunae, destroying the normal cotyledonary arrangement of the villi. PMID- 30299281 TI - What is a Right Distal Fusion Level for Prevention of Sagittal Imbalance in Multilevel Posterior Cervical Spine Surgery: C7 or T1? AB - STUDY DESIGN: This was a retrospective cohort study. OBJECTIVE: To evaluate the sagittal alignment and T1 slope after multilevel posterior cervical fusion surgery depending on the distal fusion level; C7 or T1, and find out the appropriate distal fusion level. SUMMARY OF BACKGROUND DATA: The sagittal balance of the cervical spine is known to be affected by cervical lordosis and T1 slope. However, T1 slope is not a constant parameter that can be frequently changed after the surgery. Furthermore, useful studies to help guide surgeons in decision making as to the most appropriate distal level of fusion for cervical sagittal balance are very limited. MATERIALS AND METHODS: From 2014 to 2015, 50 patients who underwent multilevel posterior cervical fusion surgery were evaluated and followed up for >2 years. Group 1 was composed of 29 patients whose distal fusion level was C7. Group 2 was composed of 21 patients whose distal fusion level was T1. C1-C2 lordosis, C2-C7 lordosis, C2-C7 sagittal vertical axis (SVA), and T1 slope were measured on preoperative and the last follow-up. RESULTS: In group 1, C2-C7 SVA (23.1->30.4 mm, P=0.043) was worsened, and T1 slope (22.3->32.9 degrees, P=0.001) was increased after the surgery. In group 2, no significant change occurred in C2-C7 SVA after the surgery (25.3 ->23.6 mm, P=0.648). The last follow-up T1 slope was similar with preoperative T1 slope (22.7->21.8 degrees, P=0.04) in group 2. CONCLUSIONS: This study showed that sagittal alignment became worse after the multilevel posterior cervical surgery when distal fusion level was stopped at C7, which was associated with increase of T1 slope. However, when we extended the distal fusion level to T1, T1 slope was not changed after the surgery. Therefore, sagittal alignment was maintained after the surgery. On the basis of the results of this study, we recommend distal fusion extends to T1. LEVEL OF EVIDENCE: Level III. PMID- 30299282 TI - Do Cervical Spine Surgery Patients Recall Their Preoperative Status?: A Cohort Study of Recall Bias in Patient-reported Outcomes. AB - STUDY DESIGN: This is a prospective cohort study. OBJECTIVE: To characterize the accuracy of patient recollection of preoperative symptoms after cervical spine surgery. SUMMARY OF BACKGROUND DATA: Recall bias is a well-known source of systematic error. The accuracy of patient recall after cervical spine surgery remains unknown. METHODS: Consecutive patients undergoing cervical spine surgery for myelopathy or radiculopathy were enrolled. Neck and arm numeric pain scores and Neck Disability Indices were recorded preoperatively. Patients were asked to recall their preoperative status at either short (<1 y) or long-term (>=1 y) follow-up. Actual and recalled scores were compared using paired t tests and relations were quantified using the Pearson correlation coefficients. Multivariable linear regression was used to identify factors impacting recollection. RESULTS: In total, 73 patients with a mean age of 58.2 years were included. Compared with their preoperative scores, patients showed significant improvement in neck pain [mean difference (MD)=-2.9; 95% confidence intervals (CIs), -3.5 to -2.3], arm pain (MD, -3.4; 95% CI, -4.0 to -2.8), and disability (MD, -12.4%; 95% CI, -16.9 to -7.9). Patient recollection of preoperative status was significantly more severe than actual for neck pain (MD, +1.5; 95% CI, 0.8 2.2), arm pain (MD, +2.3; 95% CI, 1.6-3.0), and disability (MD, +5.8%; 95% CI, 2.4-9.2). Moderate correlation between actual and recalled scores with regard to neck (r=0.41), arm (r=0.50) pain, and disability (r=0.67) was seen. This was maintained across age, sex, and time between date of surgery and recollection. Over 30% of patients switched their predominant symptom from neck-to-arm pain or vice versa on recall of their preoperative symptoms. CONCLUSIONS: Relying on patient recollection does not provide an accurate measure of preoperative status after cervical spine surgery. Prospective and not retrospective collection of patient-reported outcomes remain the gold standard to measure and interpret outcomes after cervical spine surgery. Recall bias has the potential to affect patient satisfaction and requires further study. PMID- 30299283 TI - Endothelial Cell Loss in Obstetric Forceps-Related Corneal Injury: A Longitudinal Specular Microscopic Study. AB - PURPOSE: To assess the impact of ocular trauma associated with obstetric forceps delivery on the corneal endothelium in children. METHODS: Five patients who attended the Hospital for Sick Children, Toronto, between 2013 and 2016 with a diagnosis of unilateral obstetrical forceps-related corneal injury were included. Clinical presentation, best-corrected visual acuity, corneal endothelial cell density (ECD, cells/mm), and measures of cellular morphology were obtained. RESULTS: The mean follow-up duration was 30 +/- 10 months. Mean ECD in the affected eye at initial assessment was significantly lower than that of the fellow eye (2576 +/- 733 vs. 3481 +/- 288 cells/mm, P = 0.02). At final follow up, mean ECD was 3293 +/- 175 and 1907 +/- 524 cells/mm in the normal and affected eyes, respectively (P = 0.004). The mean annual rate of the ECD decrease was higher in the affected eyes than in the normal eyes (9.1% +/- 4.2% vs. 2.0% +/- 2.5%), although this difference was not statistically significant (P = 0.06). CONCLUSIONS: In children with forceps-related corneal injury, lower ECD with a higher annual decrease can be assessed with specular microscopy for risk stratification and parental counseling purposes. PMID- 30299284 TI - Nurse Decision Making and Attitudes About Circuit Disconnection During Ventilator Therapy at a Swedish Neonatal Intensive Care Unit. AB - BACKGROUND: There are many challenges to providing care to infants in need of ventilator therapy. Yet, few studies describe the practical handling of the ventilator circuit during nursing care. PURPOSE: To describe neonatal intensive care unit (NICU) nurses' decision making regarding whether or not to disconnect the ventilator circuit when changing the infant's position and to investigate the grounds for their decisions. METHODS: A descriptive questionnaire study with both quantitative and qualitative elements was conducted. In 2015, a convenience sample of nurses working in an NICU completed a questionnaire including both closed-ended and open-ended, free-text questions. Answers to the closed-ended questions were analyzed with descriptive statistics, whereas answers to the free text questions were analyzed using qualitative content analysis. RESULTS: Nurses' decisions on whether to disconnect or keep the ventilator circuit closed were based on the infant's needs for ventilator support. The nurses gave several reasons and motivations both for why they disconnected the circuit and for why they did not. The handling of the circuit and the reasons and motivations given were inconsistent among the nurses. IMPLICATIONS FOR PRACTICE: This study highlights the need for continuous, repetitive education and training for NICU nurses, as well as demonstrating the importance of clear and distinct guidelines and working methods regarding the care of infants on ventilator support. IMPLICATIONS FOR RESEARCH: Future research should continue to find ways of working and handling an infant on ventilator support that are least harmful to the infant. PMID- 30299285 TI - Is a Cephalomedullary Nail Durable Treatment for Patients With Metastatic Peritrochanteric Disease? AB - BACKGROUND: Although cephalomedullary nail fixation is often used for metastatic peritrochanteric lesions of the femur, there is concern regarding the durability of the implant in comparison to endoprosthetic reconstruction. Previous studies have reported the proportion of patients who undergo reoperation for loss of stability, but the adequacy of the construct has not been critically evaluated in a competing risk analysis that incorporates death of the patient in the calculation. QUESTIONS/PURPOSES: (1) What is the cumulative incidence of reoperation of cephalomedullary nails with death as a competing risk for metastatic lesions of the proximal femur? (2) What is the survival of patients with metastases to the proximal femur after cephalomedullary nailing? (3) What clinical factors are associated with implant stability in these patients? METHODS: Between 1990 and 2009, 11 surgeons at one center treated 217 patients with cephalomedullary nails for metastatic proximal femoral lesions. This represented 40% (217 of 544) of the patients undergoing surgery for metastases in this location during the study period. In general, we used cephalomedullary nails when there was normal bone in the femoral head, no fracture in the neck, and a moderate-sized lesion; we favored bipolar hemiarthroplasty for femoral neck fractures and disease affecting the femoral head; finally, we used proximal femoral endoprosthetic replacement for large lesions with severe bone destruction. A retrospective study was conducted of 199 patients with cephalomedullary nails for peritrochanteric metastases from 1990 to 2009. Pathologic fracture, defined as a breach in cortex with a clear fracture line either with or without displacement, was present in 61 patients. The most common primary cancers were breast (42 of 199 patients [21%]), lung (37 of 199 patients [18%]), and renal cell (34 of 199 patients [17%]). A competing risk analysis was performed to describe the cumulative incidence of implant revision. Patient overall survival was assessed by Kaplan-Meier survivorship. A univariate analysis was performed to determine whether there was an association between revision surgery and various patient factors, including tumor histology, pathologic fracture, cementation, and radiation. RESULTS: Loss of implant stability necessitating revision surgery occurred in 19 of 199 patients (10%). In a competing risk analysis with death of the patient as the competing event, the cumulative incidence of revision surgery was 5% (95% confidence interval [CI], 3% 9%) at 12 months and 9% (95% CI, 5%-13%) at 5 years. Using Kaplan-Meier analysis, the overall patient survival was 31% (95% CI, 25%-37%) at 12 months and 5% (95% CI, 3%-9%) at 60 months. Patients with lung cancer had the shortest overall survival of 11% (95% CI, 1%-21%) at 12 months, and patients with multiple myeloma had the longest overall survival of 71% (95% CI, 49%-94%) at 12 months (p < 0.001). Duration of patient survival beyond the median 7 months was the only factor associated with a greater likelihood of revision surgery. Factors not associated with revision included tumor histology, pathologic fracture, closed versus open nailing, cementation, gender, age, and postoperative radiation. CONCLUSIONS: The competing risk analysis demonstrates a relatively low cumulative incidence of reoperation and suggests that cephalomedullary nailing is reasonable for patients with moderate-sized proximal femoral metastasis not affecting the femoral head. For the large majority of patients, the construct achieves the goal of stabilizing the femur for the duration of the patient's life. Longer patient survival was associated with greater risk of revision surgery, but no particular tumor histology was found to have a greater cumulative incidence of reoperation. Future work with a larger number of patients and stricter surgical indications may be needed to corroborate these findings. LEVEL OF EVIDENCE: Level III, therapeutic study.

RECENT FINDINGS: Implementation of various scoring systems in combination with video capsule endoscopy assists in stratifying and managing nonvariceal upper gastrointestinal bleeding. New techniques such as thermocoagulation and hemoclips are useful to treat bleeding.

In this chapter, we will be discussing various scores to stratify nonvariceal upper gastrointestinal bleeding and techniques to stop bleeding. PMID- 30299289 TI - Xenobiotic and endobiotic handling by the mucosal immune system. AB - PURPOSE OF REVIEW: Mucosal immune cells in the intestinal tract are continuously exposed to a barrage of both foreign and endogenously generated metabolites, termed xenobiotics, and endobiotics, respectively. This review summarizes recent insights into the mechanisms by which xenobiotics and endobiotics regulate intestinal immunity and inflammation. RECENT FINDINGS: The community of enteric microbes (i.e., microbiota) has profound impacts on the development and function of the mucosal immune system. The composition and function of gut microbiota is dynamically regulated by diet, and this interplay dictates which and how many immunomodulatory xenobiotics are present in the intestine. Microbiota also regulate the concentration and composition of circulating bile acids, an abundant class of liver-derived endobiotics with pleotropic immunoregulatory activities. A growing body of literature is emerging that sheds new light on the mechanisms by which xenobiotics and endobiotics interact with germline-encoded receptors and transporters to shape mucosal immune function. SUMMARY: The complex and dynamic interplay among xenobiotics, endobiotics, and the mucosal immune system is a new frontier in mucosal immunology that is proving fruitful for the discovery of novel and pharmacologically accessible mechanisms with relevance to human inflammatory diseases. PMID- 30299290 TI - Mucosal immune responses to fungi and the implications for inflammatory bowel disease. AB - PURPOSE OF REVIEW: The intestinal microbiota plays a central role in inflammatory diseases of the gut. Although most investigations regarding how the mucosal immune system interacts with the microbiota have focused on bacteria, recent studies are elucidating the additional role of commensal fungi in health and disease in the gut. RECENT FINDINGS: New technical approaches are defining the makeup of the fungal communities in the intestines of humans and mice. The reported composition of these communities is influenced by the approaches used to define the fungi. Changes in the intestinal mycobiota are associated with gut inflammation in patients with inflammatory bowel disease and in mouse models of colitis. Recent studies are beginning to elucidate the mechanisms by which the mucosal immune system interacts with and is influenced by intestinal fungi. SUMMARY: Studies clearly demonstrate the presence of intestinal fungi and document the ability of the mucosal immune system to recognize and respond to fungi. Future studies will further investigate whether intestinal fungi directly influence intestinal disease and what cellular, molecular, and genetic mechanisms contribute. PMID- 30299291 TI - Impact of ovarian function suppression in premenopausal women with estrogen receptor-positive early breast cancer. AB - PURPOSE OF REVIEW: This manuscript aims at providing an updated overview on the role of adding ovarian function suppression to tamoxifen or an aromatase inhibitor as adjuvant endocrine therapy in premenopausal women with estrogen receptor-positive early breast cancer. RECENT FINDINGS: Until recently, tamoxifen alone was the only recommended adjuvant treatment option for premenopausal women with estrogen receptor-positive disease. However, recent important evidence has contributed to significantly modify the endocrine treatment landscape in this setting. SUMMARY: With the only exception of patients with low-risk clinical pathological features characterized by excellent survival outcomes with tamoxifen alone, the use of ovarian function suppression is to be considered standard of care for most of premenopausal women with estrogen receptor-positive disease. Regarding the choice of its best partner as endocrine agent, the available data suggest that the higher the risk of disease recurrence the larger benefit can be observed with a more profound estrogen deprivation that can be obtained with ovarian function suppression and an aromatase inhibitor as compared to ovarian function suppression and tamoxifen. Despite the significant improvement in our understanding on the role of ovarian function suppression in this setting, several unanswered questions remain and further research efforts are needed in the field. PMID- 30299292 TI - Risk stratification in early breast cancer in premenopausal and postmenopausal women: integrating genomic assays with clinicopathological features. AB - PURPOSE OF REVIEW: There is growing consensus that genomic assays provide useful complementary information to clinicopathological features in oestrogen receptor positive breast cancers. Here, ongoing research with multigene tests used for postmenopausal breast cancer and new emerging prognostic and predictive markers for pre and postmenopausal women are summarised. RECENT FINDINGS: Results of the TAILORx trial have shown that women with an intermediate risk score do not benefit from adjuvant chemotherapy. Prosgina has been further investigated in a contemporary patient population in postmenopausal women and its use has been extended for premenopausal women. The EndoPredict was extensively used in decision-impact studies showing that its use can potentially reduce the need for adjuvant chemotherapy. Several new genomic assays have been developed, with some of them showing promising use for women with early oestrogen receptor-positive breast cancer. SUMMARY: New areas of research for prediction of recurrence and risk stratification involve the development of immune gene signatures that carry modest but significant prognostic value. The recent expansion of high-throughput technology platforms including circulating tumour DNA/RNA and microRNA offer new opportunities to improve prediction models, particularly in women with oestrogen receptor-negative disease and premenopausal women. Genomic assays have clearly improved prognostication of early oestrogen receptor-positive breast cancer but it is clear that standard clinicopathological parameters are still very important when identifying patient for adjuvant chemotherapy.

AB - Reports on pacemaker placement/relocation surgery under pectoralis nerve block are limited. We herein report a case involving a 74-year-old woman with an infected cardiac pacemaker generator who underwent pacemaker relocation surgery under an ultrasound-guided pectoralis nerve block. On preoperative evaluation, she had congestive heart failure, type 2 diabetes mellitus, and a pacer-dependent heart rhythm. She was considered to be at high risk for general anesthesia. Thus, an ultrasound-guided pectoralis nerve block was planned. The surgery was completed successfully, without notable complications.

AB - There are no case reports of malignant hyperthermia in pediatric patients treated on cardiopulmonary bypass (CPB). We report the case of a 10-year-old boy undergoing aortic valve replacement. The patient developed progressive tachycardia and hypercarbia. In addition, EtCO2 and PaCO2 were equal and myoglobinuria was suspected given darkened urine. Numerous dantrolene boluses were given on CPB, and a dantrolene infusion was started. The patient's base deficit and creatine phosphokinase normalized by postoperative day 2. This case demonstrates the importance of expeditious diagnosis of malignant hyperthermia, and the need for additional dantrolene when treating patients whose blood volume is diluted on CPB.

AB - Dual epidural catheter (DEC) therapy improves postoperative pain control in scoliosis correction surgery, esophagectomies, and labor. Reports about the use of a second epidural catheter to improve pain control after abdominal surgeries are sparse. We describe the successful use of unplanned DEC therapy in 2 complex pain patients who underwent large exploratory laparotomies. In both patients, the addition of the second catheter led to improved pain control and mobility and reduced side effects from adjuvant intravenous analgesics. DEC therapy merits consideration as an additional tool for managing postoperative pain after large abdominal surgeries despite existing incomplete epidural analgesia. PMID- 30299297 TI - In Response. PMID- 30299298 TI - Evaluation of 30 Day Readmissions After Index Ventricular Assist Device Implantation in the United States. AB - Ventricular assist device (VAD) implantation has improved quality of life and short-term survival for advanced heart failure patients. There are limited data from single-center studies addressing the characteristics and etiologies of 30 day readmissions after VAD implant. We used the Nationwide Readmissions Database (NRD) 2014 to identify insertion of implantable heart assist system during index admission. Primary and secondary outcomes were 30 day readmissions and leading etiologies, respectively. We analyzed 1,481 patients who received VAD during the primary admission of whom 1,315 patients survived to hospital discharge (mortality rate 11.2%), and 60.6% were discharged to a nursing facility. One hundred and thirty-one (10.0%) patients were readmitted within 30 days of primary hospitalization. Leading etiologies of 30 day readmission were bleeding (24%), heart failure (18%), and device complications (14%). Mean length of stay during readmission was 13.8 days with a mortality rate of 2.1%. Fifty percent of 30 day readmissions were readmitted from day 22 to 30. Variables for predictors of 30 day readmissions were not statistically significant. By identifying gastrointestinal bleeding, heart failure, and device complications as leading etiologies of 30 day readmission post-VAD implantation, providers can potentially modify practices to prevent hospital readmissions, decreasing cost of care, and improving the quality of life of patients. PMID- 30299299 TI - Pharmacokinetics of Sildenafil in Patients with a Left Ventricular Assist Device: A Word of Caution. AB - We compared maximal plasma concentrations (Cmax) of sildenafil and metabolite n desmethyl sildenafil in 12 inpatients with left ventricular assist devices (LVADs) on sildenafil (60 mg/day) to the reference range. Sildenafil Cmax (156.8 +/- 124.5 ng/ml) was elevated in 66% of patients, with a two to fivefold increase over the upper limit of the reference range in 25% of patients. Metabolite Cmax (133.3 +/- 102.0 ng/ml) was elevated in 75% of patients, with a three to sevenfold increase over the upper limit of the reference range in 40% of patients. Patients with heart failure and LVADs are at increased risk of concentrated-related sildenafil adverse events. PMID- 30299300 TI - Bivalirudin and ECLS: Commentary and Considerations.

Current approaches to treat PT are limited to LVAD with variable outcomes depending on the management strategy implemented. Moreover the management of PT in patients with BIVAD support, specifically to the right ventricular assist device (RVAD), is unknown. We describe the first care series to date on the management of PT in patients with durable right ventricular assist device and their outcomes. PMID- 30299303 TI - Chronic In Vivo Test of a Right Heart Replacement Blood Pump for Failed Fontan Circulation. AB - An implantable rotary blood pump was developed to provide long-term mechanical right heart support for patients who have failing Fontan circulation. The objective of this study was to evaluate the pump in vivo in a 30 day sheep study. Pump speed was set at 3,900 rpm for the duration of the study, and pump power was between 4.3 and 4.6 W. The pump inlet pressures for the superior vena cava (SVC) and inferior vena cava (IVC) were 14 +/- 15 and 11 +/- 15 mm Hg, respectively, over the duration of the study. Hematocrit remained stable at 30% +/- 4%. Partial thromboplastin time (PTT) steadily increased from 30 s preoperatively to a high of 59 s on postoperative day 20, while prothrombin time (PT) remained at 20 +/- 2 s for the duration of the study. The implantation and postoperative recovery were successful, and the animal demonstrated normal physiologic pulmonary and venous pressures and cardiac output. On pump inspection, the IVC and SVC inlets were completely clear of any deposits, but there were small thrombi (approximately 0.5 mm diameter) between each of the three rotor blades and along 20% of the parting line of the two volute halves. A complete right heart bypass was performed, postoperative recovery was successful, and the pump demonstrated adequate circulatory support and normal physiologic pulmonary and venous pressures. This study was the first successful test of a right heart replacement device in a chronic animal study. PMID- 30299304 TI - Use of an Ecological Momentary Assessment Application to Assess the Effects of Auricular Point Acupressure for Chronic Low Back Pain. AB - The purpose of this pilot study was to assess the feasibility and usability of an ecological momentary assessment smartphone application. The app collected real time data on chronic low back pain and time-contingent ecological momentary assessment surveys during a 4-week auricular point acupressure intervention, and on the consistency between recalled and momentary clinical measures. Eighteen participants received auricular point acupressure treatment weekly for 4 weeks. Each participant was provided a smartphone with the ecological momentary assessment application installed, along with instructions for use. The primary outcomes comprised pain intensity, pain interference with daily activity, sleep quality score, and medication usage. System Usability Scale and adherence were also measured. According to the results, the rate of adherence for completion of the random ecological momentary assessment survey was 87%. The usability score for the ecological momentary assessment application was reported as 78. The average recalled pain intensity was higher than the mean momentary pain intensity. Self-reported average pain interference with daily activities showed a similar result. Spearman rank correlation coefficients were greater than +0.70; P < .01 for the associations among recalled and momentary measurements. In conclusion, the study demonstrated promising adherence rates and supported the usability and feasibility of using an ecological momentary assessment application on a smartphone to collect real-time data on chronic lower back pain, which eliminated recall bias.

AB - While previous research has examined specific ways that nurses have used smartphones for work purposes in clinical settings, large-sample quantitative studies are limited, particularly in Asia. To address this research gap, this study provided a ranking on how nurses have used their smartphones for work purposes in clinical settings and identified differences based on demographic and organizational factors. In January to June 2017, a pen-and-paper survey was administered to 517 staff nurses employed in 19 tertiary-level general hospitals in Metro Manila, Philippines. Results show that nurses frequently used their smartphones to exchange voice calls and text messages with other nurses and doctors. Results also showed that specific items reflecting the use of smartphones for communication purposes differed according to gender, age, hospital ownership, nursing area, number of patients handled in last shift, and presence of a hospital-provided mobile phone. Next, some items for information seeking purposes differed according to highest educational attainment and years of clinical experience. Moreover, some items for documentation purposes differed according to age, hospital ownership, and number of patients handled in last shift. Overall, the results of this study can be used to guide policies on the use of smartphones in clinical settings. PMID- 30299306 TI - Towards the integration of pharmacogenetics in psychiatry: a minimum, evidence based genetic testing panel. AB - PURPOSE OF REVIEW: The implementation of pharmacogenetic testing in psychiatry is underway but is not yet standard protocol. Barriers to pharmacogenetics becoming standard practice are the lack of translation of evidence-based recommendations and standardization of genetic testing panels. As for the latter, there are currently no regulatory standards related to the gene and allele content of testing panels used to derive medication selection and dosing advice. To address these barriers, we summarize the current gene-drug interaction knowledgebase and proposed a minimum gene and allele set for pharmacogenetic testing in psychiatry. RECENT FINDINGS: The Pharmacogenomics Knowledgebase has cataloged 448 gene-drug interactions relevant to psychiatry based on the current scientific literature, drug labels, and pharmacogenetic-based implementation guidelines. A majority of these interactions involved two cytochrome P450 enzymes (CYP2D6 and CYP2C19) and antidepressant medications, however, CYP2C9, HLA-A, and HLA-B are relevant to mood stabilizers/anticonvulsants. SUMMARY: On the basis of evidence base, we proposed a minimum gene and allele set for pharmacogenetic testing in psychiatry that includes 16 variant alleles within five genes (CYP2C9, CYP2C19, CYP2D6, HLA A, HLA-B). The intent is to assist clinicians in judging the gene and allele content of pharmacogenetic tests and to facilitate pharmacogenetic testing as a standard protocol and companion tool for psychotropic medication selection and dosing. PMID- 30299307 TI - Schema therapy conceptualization of personality functioning and traits in ICD-11 and DSM-5. AB - PURPOSE OF REVIEW: Schema therapy conceptualizes personality disorders in terms of modes and underlying schemas. This article reviews the literature on schema therapy conceptualization of personality disorder functioning and traits, and proposes how these findings apply to novel personality disorder classification in ICD-11 and the DSM-5 Alternative Model of Personality Disorders (AMPD). RECENT FINDINGS: Maladaptive schemas and modes are generally associated with personality dysfunction and traits in conceptually coherent ways. The healthy adult mode, a transdiagnostic core concept in schema therapy, corresponds to the ICD-11 and DSM 5-AMPD features of core personality functioning. Modes and underlying schemas substantially overlap with specific ICD-11 and DSM-5-AMPD traits, which denote individual themes and styles of personality dysfunction. SUMMARY: The dimensional personality disorder framework in ICD-11 and DSM-5-AMPD is largely compatible with the schema therapy model. The ICD-11 and DSM-5-AMPD provide a scientifically derived and theory-free framework for all practitioners, which may be connected to clinical theory of schema therapy in a coherent manner. Level of personality functioning can be conceptualized as healthy adult functioning (e.g. sense of identity, self-worth, emotion regulation, intimacy, and fulfillment), which inform intensity of treatment. Trait qualifiers can be conceptualized by associated modes (e.g., compliant surrender) and underlying schemas (e.g. abandonment), which inform focus and style of treatment. PMID- 30299308 TI - Dialysis catheters in the ICU: selection, insertion and maintenance. AB - PURPOSE OF REVIEW: Choosing the best catheter for renal replacement therapy (RRT) is not an easy task. Beyond catheter length, many of its properties can influence effectiveness of the RRT session. Maintenance between sessions, particularly the locking solution, also impacts catheter lifespan and infection rates. RECENT FINDINGS: Many innovations in dialysis catheters have been proposed by the industry over the past decade, including the material used, the shape of the lumens and the position of the inflow and outflow holes. Impregnated catheters have also been developed to prevent catheter-related infections. Many locking solutions are available, either for maintaining catheter patency or for preventing infections. SUMMARY: Although studies conducted in the specific context of the ICU are still scarce, some conclusions can be drawn. Catheter length must be adapted to the insertion site to reach an area of high blood flow. Kidney-shape lumens appear to be less thrombogenic and seem to prevent catheter dysfunction. Catheter tip and lumen holes also affect catheter function. For catheter locking, 4% citrate appears nowadays as one of the best options, but taurolidine-based solutions are also interesting. PMID- 30299309 TI - Noninvasive ventilation as acute therapy. AB - PURPOSE OF REVIEW: Noninvasive ventilation (NIV) is widely used in ICU patients to treat or to prevent acute respiratory failure. Whereas its physiological effects are clearly beneficial in hypercapnic patients, it could be deleterious in hypoxemic patients without hypercapnia. RECENT FINDINGS: NIV should be cautiously used in patients with de-novo respiratory failure, the vast majority of whom meet the criteria for acute respiratory distress syndrome. Spontaneous breathing with high tidal volumes may worsen lung injury in these patients, and recent findings suggest that NIV may increase the risk of mortality. Even though high-flow oxygen therapy is increasingly applied in this context, NIV remains recommended for management of immunocompromised patients with acute respiratory failure. NIV should be the first-line oxygenation strategy in patients with acute hypercapnic respiratory failure when pH is equal to or below 7.35. Prophylactic NIV prevents respiratory failure after extubation of patients at high risk of reintubation. SUMMARY: Most previous studies have compared NIV with standard oxygen, and recent recommendations have been established from these findings. Given the growing use of high-flow oxygen therapy, new studies are needed to compare NIV versus high-flow oxygen therapy so as to better define the appropriate indications for each treatment. PMID- 30299310 TI - Major surgery and the immune system: from pathophysiology to treatment. AB - PURPOSE OF REVIEW: The purpose of this review is to provide an overview of the immune response to major surgery, and the ways in which it may be modulated to improve postoperative outcomes. RECENT FINDINGS: Data from patients who have undergone a variety of tissue injuries (surgery, burns, sepsis, trauma) have shown the presence of a conserved 'genomic storm' that alters the leukocyte transcriptome, with upregulation of the innate immune response and concomitant downregulation of the adaptive immune response. The innate and adaptive immune systems are often regarded largely distinct. However, more recent evidence suggests there are critical connections between the two arms of the immune response, whereby innate immune cells are able to suppress the adaptive response. SUMMARY: The immune system is critical to the host response to tissue injury occurring due to surgery. However, the physiological processes required to resolve the surgical insult can also contribute to sequelae such as cognitive decline, pneumonia and acute kidney injury. Our understanding of the immune pathogenesis underlying these complications is improving, leading to interest in the development of immunomodulatory therapies, which aim to permit host defence whilst ameliorating postoperative complications. PMID- 30299311 TI - Perioperative management of obese patient. AB - PURPOSE OF REVIEW: The volume of bariatric and nonbariatric surgical procedures on obese patients is dramatically increasing worldwide over the past years. In this review, we discuss the physiopathlogy of respiratory function during anesthesia in obese patients, the stratification of perioperative risk to develop intraoperative and postoperative pulmonary complications, the optimization of airway management, and perioperative ventilation, including postoperative respiratory assistance. RECENT FINDINGS: Scores have been proposed to stratify the risk of surgical patients, some of which were specifically developed for obese patients. Most scores identify obstructive sleep apnea and elevated BMI as independent risk factors. Obese patients might be at risk of difficult intubation and mask ventilation, and also of developing postoperative pulmonary complications. Intraoperative ventilation settings affect clinical outcome, but the optimal ventilation strategy is still to be determined. Opioid-free regimens are being widely investigated. Postoperative monitoring and respiratory assistance are necessary in selected patients. Early mobilization and physiotherapy are mandatory. SUMMARY: Obese patients are at higher risk of perioperative complications, mainly associated with those related to the respiratory function. An appropriate preoperative evaluation, intraoperative management, and postoperative support and monitoring is essential to improve outcome and increase the safety of the surgical procedure. PMID- 30299312 TI - How to optimize critical care resources in surgical patients: intensive care without physical borders. AB - PURPOSE OF REVIEW: Timely identification of surgery patients at risk of postoperative complications is important to improve the care process, including critical care. This review discusses epidemiology and impact of postoperative complications; prediction scores used to identify surgical patients at risk of complications, and the role of critical care in the postoperative management. It also discusses how critical care may change, with respect to admission to the ICU. RECENT FINDING: Optimization of postoperative outcome, next to preoperative and intraoperative optimization, consists of using risk scores to early identify patients at risk of developing complications. Critical care consultancy should be performed in the ward after surgery, if necessary. ICUs could work at different levels of intensity, but remain preferably multidisciplinary, combining care for surgical and medical patients. ICU admission should still be considered for those patients at very high risk of postoperative complications, and for those receiving complex or emergency interventions. SUMMARY: To optimize critical care resources for surgery patients at high risk of postoperative complications, the care process should not only include critical care and monitoring in ICUs, but also strict monitoring in the ward. Prediction scores could help to timely identify patients at risk. More intense care (monitoring) outside the ICU could improve outcome. This concept of critical care without borders could be implemented in the near future to optimize the local resources and improve patient safety. Predict more, do less in ICUs, and more in the ward.

PMID- 30299314 TI - Renal replacement therapy in the ICU: continued controversy despite recent advances. PMID- 30299315 TI - Risk factors for extrahepatic cholangiocarcinoma: a case-control study in China. AB - To investigate risk factors for extrahepatic cholangiocarcinoma (ECC) in China. A total of 200 ECC cases and 200 matched control were included in the study. The presence of cigarette smoking, alcohol drinking, choledocholithiasis, primary sclerosing cholangitis, liver fluke infection (Clonorchis sinensis), diabetes mellitus, was investigated through clinical records. Blood from all cases was tested for hepatitis B surface antigen. Odds ratios (OR) and 95% confidence intervals (CIs) were estimated using conditional logistic regression. Compared with controls, ECC patients had a higher prevalence of cigarette smoking (61.0 vs. 47.0%, P=0.007), alcohol drinking (17.5 vs. 3.5%, P<0.000), and choledocholithiasis (6.0 vs. 1.0%, P=0.011). By multivariate analysis, the significant risk factors for the development of ECC were current smoking (OR=1.90, 95% CI=1.08-3.34), heavy alcohol drinking (OR=2.08, 95% CI=1.39-3.13), and choledocholithiasis (OR=6.68, 95% CI=1.48-30.27). The prevalence of hepatitis B virus infection, diabetes mellitus were not significantly different between cases and controls. These findings suggest that smoking, alcohol drinking, and choledocholithiasis are positive risk factors for the development of ECC in China. PMID- 30299316 TI - Vitamin D receptor expression and serum 25(OH)D concentration inversely associates with burden of neurofibromas. AB - Vitamin D and its receptor may play a role in preventing tumor development and progression. As such antineoplastic effects are expected to be weak and to act over long periods, conditions with increased tumor incidence, such as the neurofibromatosis type 1 (NF1), provide suitable study models. We previously found an inverse correlation of serum 25(OH)D concentration with number of neurofibromas in NF1. Here we aim to further explore the role of the vitamin D receptor. A total of 141 adult NF1 patients were included in the study. For 101 of them, serum vitamin 25(OH)D data were available. From 87 patients, blood samples were obtained in PaxGene tubes containing a reagent to stabilize RNA immediately. mRNA of the vitamin D receptor (VDR) gene (coding for the vitamin D receptor) was measured by means of RT-PCR. Correlation of laboratory data with NF1-related tumors was statistically evaluated. Vitamin D receptor in NF1-tumors was examined by means of immunohistochemistry using an antibody against the vitamin D1 receptor. The number of dermal neurofibromas was significantly inversely correlated with VDR mRNA level and with serum 25(OH)D concentration in NF1 patients. In contrast, plexiform neurofibroma and malignant peripheral nerve sheath tumor did not correlate with these two parameters. Immunostaining did not detect vitamin D receptor in NF1-tumors. Both vitamin D and its receptor may play a role in suppressing the development of neurofibromas. Sustaining 25(OH)D at an adequate level may contribute to controlling neurofibromas and possibly also other tumors. This is especially important for individuals with lower expression of VDR. PMID- 30299318 TI - Expanding adolescent access to hormonal contraception: an update on over-the counter, pharmacist prescribing, and web-based telehealth approaches. AB - PURPOSE OF REVIEW: Hormonal contraceptives are largely responsible for recent declines in unintended adolescent pregnancies, with oral contraceptives being the most commonly used. Young people face multiple barriers to accessing effective contraception in clinical settings. This article reviews innovations in contraceptive access. RECENT FINDINGS: The three biggest innovations are over-the counter oral contraceptives (OTC-OCs), pharmacist-prescribing, and web-based telehealth platforms. In many countries, oral contraceptives are available OTC, and FDA trials for OTC-OCs are underway in the United States. Many states have passed legislation allowing pharmacists to prescribe contraceptives after a brief health screening. Web-based telehealth platforms also provide prescription contraceptive access. There is a small but growing body of literature that demonstrates young people's interest in, and capacity to consent to, hormonal contraceptives in nontraditional settings. State-to-state variability in minor consent, pharmacist prescribing, and telehealth laws act as barriers to young people's access to these newer options. SUMMARY: Access to hormonal contraception is expanding outside of clinical settings, reducing barriers. Adolescents' unique needs should be considered in the design, implementation, and evaluation of these new approaches. More data is needed to ensure that adolescents are not excluded from expanded contraceptive access options, as they are disproportionately affected by unintended pregnancy. PMID- 30299317 TI - The challenge of cardiomyopathies and heart failure in pregnancy. AB - PURPOSE OF REVIEW: To discuss the risk preexisting or new onset cardiomyopathy/heart failure (CMP/heart failure) in pregnant woman, and recent insights regarding their management and therapy. RECENT FINDINGS: Recent data from the European Registry on Pregnancy and Heart disease of the European Society of Cardiology (ROPAC) suggest that, after an adequate prepregnancy evaluation in specialized centres, the vast majority of pregnancies are safe for both mother and foetus. A tailored approach is required according to cardiac phenotype (i.e. type of cardiomyopathy), clinical and functional status, and new potential treatments (i.e. bromocriptine in patients with peripartum cardiomyopathy). SUMMARY: In clinical practice, prepregnancy cardiac evaluation is mandatory, including evaluation of the clinical status, standard ECG (and 24-48 h monitoring, whenever required), and imaging, to define the individual risk profile. In presence of severe symptoms (advanced New York Heart Association class), cardiac dysfunction (moderate-severe reduced ejection fraction), haemodynamic load (left ventricular outflow tract obstruction, pulmonary hypertension), pregnancy is contraindicated. A tailored monitoring is warranted in other cases (mild-moderate risk pregnancies). Likewise, in women who develop PPCM, a risk stratification and tailored monitoring and therapy should be achieved by an expert, multidisciplinary team, including cardiologists, gynaecologists, obstetricians, genetic counsellor, and psychologists. PMID- 30299319 TI - Clinical significance of cerebroplacental ratio. AB - PURPOSE OF REVIEW: Two-thirds of the pregnancies complicated by stillbirth demonstrate growth restriction. Identification of the foetus at risk of growth restriction is essential to reduce the risk of stillbirth. The aim of this review is to critically appraise the current evidence regarding clinical utility of cerebroplacental ratio (CPR) in antenatal surveillance. RECENT FINDINGS: The CPR has emerged as an assessment tool for foetuses at increased risk of growth disorders. CPR is a better predictor of adverse events compared with middle cerebral artery or umbilical artery Doppler alone. The predictive value of CPR for adverse perinatal outcomes is better for suspected small-for-gestational age foetuses compared with appropriate-for-gestational age (AGA) foetuses. CPR could be useful for the risk stratification of small-for-gestational age foetuses to determine the timing of delivery and also to calculate the risk of intrapartum compromise or prolonged admission to the neonatal care unit. Although there are many proposed cut-offs for an abnormal CPR value, evidence is currently lacking to suggest the use of one cut-off over another. CPR appears to be associated with increased risk of intrapartum foetal compromise, abnormal growth velocity, and lower birthweight in AGA foetuses as well. Moreover, birthweight differences are better explained with CPR compared to other factors such as ethnicity. However, the role of CPR in predicting adverse perinatal outcomes such as acidosis or low Apgar scores in AGA foetuses is yet to be determined. SUMMARY: CPR appears to be a useful surrogate of suboptimal foetal growth and intrauterine hypoxia and it is associated with a variety of perinatal adverse events. PMID- 30299320 TI - The patient perspective: perceptions of the quality of the abortion experience. AB - PURPOSE OF REVIEW: Abortion services are essential in sexual and reproductive health and should be held to the same standards as other health services. Patient (or person)-centeredness is a key dimension of healthcare quality that incorporates the perspectives of patients in care provision. The purpose of this review is to summarize studies published in the last year examining women's experiences with abortion care and to describe facilitators and barriers to person-centered care. RECENT FINDINGS: Considering person-centeredness in abortion care using dimensions of dignity, autonomy, privacy, communication, social support, supportive care and health facility environment allows for critical evaluation of data describing women's experiences with abortion and postabortion services. Review of the available literature shed light on the impact of social stigma, health policy and abortion restrictions on women's abortion experiences. SUMMARY: Considering multiple domains and varied settings, current data suggest abortion services worldwide generally fail to provide person centered care. Institutions and providers may be limited in their ability to provide patient-centered abortion care because of deeply embedded social stigma, institutional regulations and legal restrictions. PMID- 30299321 TI - Advances in the management of early pregnancy loss. AB - PURPOSE OF REVIEW: To describe recent advances in management of early pregnancy loss. RECENT FINDINGS: Addition of mifepristone to current protocols for medical management of miscarriage increases effectiveness of a single dose of misoprostol and significantly reduces subsequent aspiration procedures. Women with an incomplete evacuation after medical management may be treated expectantly with similar rates of complete expulsion compared with surgical management at 6 weeks. As cytogenetic analysis improves, analysis of products of conception can be performed whether collected after surgical or medical management and is an efficient strategy in starting a recurrent pregnancy loss work-up. For those seeking pregnancy after miscarriage, conception immediately following an early pregnancy loss is not associated with increased risk of subsequent miscarriage. However, recent studies suggest that the original intendedness of the pregnancy resulting in miscarriage does not predict future reproductive goals of the woman, so family planning should be discussed at the time of miscarriage. SUMMARY: Miscarriage is a common experience among reproductive-aged women and advances in medical management and modern-day aspiration techniques make the use of the sharp curette obsolete. PMID- 30299322 TI - Pelvic floor disorders in women with gynecologic malignancy. AB - PURPOSE OF REVIEW: This article serves as an update on issues relating to the intersection of pelvic floor disorders and gynecology oncology. RECENT FINDINGS: Gynecologic cancer survivors experience pelvic floor disorders (PFDs) at a higher rate than their age-matched peers, often because of shared risk factors and as sequelae of cancer treatment. Concomitant pelvic floor and oncologic surgery can serve as a method to promote quality of life. Studies have demonstrated concomitant surgery to be well tolerated in appropriately selected patients, but only about 2% of oncologic surgeries are coordinated to include the treatment of PFDs. Conversely, women undergoing surgery for PFD have a low, but real risk of occult malignancy. Therefore, preoperative counseling is warranted in select populations. This article will discuss the management of concurrent PFDs and gynecologic malignancies. SUMMARY: Healthcare providers should be familiar with screening, management and referral of women with pelvic floor disorders in the gynecologic oncology population. PMID- 30299323 TI - Ergonomics in gynecologic surgery. AB - PURPOSE OF REVIEW: Work-related musculoskeletal disorders (WMSDs) are prevalent among surgeons and result in significant disability. We aimed to review the English-language literature regarding ergonomic risk, prevalence of WMSDs, and unique ergonomic considerations of gynecologic surgery. RECENT FINDINGS: Surgeon WMSDs are prevalent, with rates ranging from 66 to 94% for open surgery, 73-100% for conventional laparoscopy, 54-87% for vaginal surgery, and 23-80% for robotic assisted surgery. Risk factors for injury in open surgery include use of loupes, headlamps, and microscopes. Unique risks in laparoscopic surgery include table and monitor position, long-shafted instruments, and poor instrument handle design. In vaginal surgery, improper table height and twisted trunk position create injury risk. Although robotic surgery offers some advantages in neck and shoulder strain, it remains associated with trunk, wrist, and finger strain. SUMMARY: WMSDs are prevalent among surgeons but have received little attention because of under-reporting of injury and logistical constraints of studying surgical ergonomics. Future research must aim to develop objective surgical ergonomics instruments and guidelines and to correlate ergonomics assessments with pain and tissue-level damage in surgeons with WMSDs. Ergonomics training should be developed and implemented in order to protect surgeons from preventable, potentially career-altering injuries. PMID- 30299324 TI - Psychological burden of haematological cancer on patient and family: is it time for a multisystem approach? AB - PURPOSE OF REVIEW: Literature addressing the psychological impact of haematological cancers on patients and their families is sparse. New evidence might prompt a change in approach to the assessment and management of psychological burden. RECENT FINDINGS: The diagnosis, treatment and surveillance of haematological cancers often have a profound psychological impact on patients and their families and can result in clinically significant problems and increased carer stress. These may manifest at any stage from diagnosis to death or living as a survivor. Some high-risk subgroups have been identified. SUMMARY: The range of diagnostic groups, wide range of data analysis time-points relative to time of diagnosis, heterogeneity of outcome measures and differing methodologies (mainly prevalence studies) confound generalization of the findings. Targeted screening of the most at-risk subpopulations at times of greatest risk seems sensible to facilitate early intervention; further work is required to establish how often to screen and the best way of doing that. None of these articles define thresholds for intervention. Clearly more psychological support is needed for patients with haematological cancers and their families, but these articles do not provide evidence to suggest what this should comprise. There remains a need for large, longitudinal multicentre studies. PMID- 30299325 TI - Endpoints in clinical trials in cancer cachexia: where to start? AB - PURPOSE OF REVIEW: The lack of agreement and knowledge of optimal endpoints in cachexia trials have impeded progress in finding interventions counteracting the devastating effects cancer cachexia has on morbidity and mortality. An endpoint should both be sensitive enough to detect change and specific enough not to be influenced by other conditions or treatments. RECENT FINDINGS: There is a wealth of potential and applied endpoints in trials investigating cachexia. As of today, there is no generally acknowledged consensus, but assessments of key factors such as body composition should continue to be applied. However, the impact and effect size necessary to achieve clinical benefit using these endpoints are not clear. Further, the use of other endpoints assessing physical function, symptom evaluation and quality of life remains to be elucidated. SUMMARY: It is essential that endpoints are clinically relevant and further research is therefore needed to develop endpoints that are meaningful for patients with cachexia. PMID- 30299326 TI - Managing anaemia in bone marrow failure syndromes. AB - PURPOSE OF REVIEW: Anaemia is a common haematological presentation in patients with bone marrow failure, yet a challenging condition to treat. As anaemia has a direct impact on the patient's symptoms, managing anaemia in the common bone marrow failure conditions, such as myelodysplastic syndrome will help to improve the quality of life. This review discusses the available treatment options and the benefit of improving the haemoglobin level. RECENT FINDINGS: Managing anaemia effectively has shown to improve the patient outcome, yet treatment option remain limited. Recently, activin inhibitors such as Luspatercept have shown to be effective in patients' refractory to ESAs and further clinical trials are ongoing to explore this further. SUMMARY: Transfusion still remains the mainstay of treatment in patients not suitable, lost response or refractory to erythropoiesis stimulating agents (ESAs). Majority of these patients are not suitable for definite treatment options such as bone marrow transplantation. The aim of treatment remains improving the quality of life and newer therapeutic options may offer better and more sustained response. PMID- 30299327 TI - NACNS Newsletter: President's Message.

AB - PURPOSE/OBJECTIVES: The purpose of this clinical nurse specialist-led initiative was to redefine the standard of care to reduce the deficit that exists between the daily amount of tube feedings prescribed versus received by patients in a surgical-trauma intensive care unit. DESCRIPTION OF THE PROJECT: Nutrition plays a vital role in health and wellness. Although nutritional recommendations are not always met by individuals on a daily basis-the presence of in-hospital malnutrition presents greater risks and complications after a surgery or traumatic event. An evidence-based algorithm for initiating and maintaining tube feedings was developed and incorporated into morning bedside report. A preintervention and postintervention chart analysis was done to calculate the amount of tube feedings received by patients during their first 5 days of admission. OUTCOMES: Preintervention data revealed that 29 patients received a mean 49.8% (SD, 21.6%) of tube feedings prescribed, and postintervention data showed 31 patients received 60.4% (SD, 18.5%) of tube feedings prescribed (P = .04). CONCLUSION: Through the implementation of a tube feeding algorithm, there was a reduction of tube feed interruptions and volume deficits during the first 5 days of admission. PMID- 30299333 TI - Alcohol Withdrawal Assessment Tool: Validity and Reliability Testing in Acute Care. AB - PURPOSE/AIMS: The purpose of this study was to validate a tool to assess alcohol withdrawal in acute care patients. Study aims included (1) establish content validity, (2) examine criterion-related validity, (3) test interrater reliability, and (4) assess nurse usability. DESIGN: A psychometric research study was designed to evaluate the Alcohol Withdrawal Assessment Tool. METHODS: Validation was conducted using an expert panel to determine content validity. The Clinical Institute Withdrawal Assessment for Alcohol-Revised was used as comparison for the criterion related validity. Interrater reliability was determined by having 2 investigators simultaneously complete the assessment on the same patients. Usability was determined using a Likert scale survey. RESULTS: The average age of participants was 53 years, with a range of 27 to 81 years. Interrater reliability was supported by a kappa statistic range of 0.61 to 0.6957, and content validity was supported by a content validity index of 1.0. Criterion-related validity was supported with a Pearson r correlation of 0.665 (P < .000). Of nurses surveyed, all answered agree or strongly agree to the usability survey. CONCLUSIONS: The assessment tool may be an effective alternative to utilize in the acute care setting. It is easy to use and drives frequency of assessment and appropriate pharmacologic treatment. PMID- 30299334 TI - Clinical Nurse Specialists' Perceptions of a Mental Health Patient Portal. AB - PURPOSE: The purposes of this study were to explore clinical nurse specialists' views of the potential influence of a mental health portal on nursing practice and to identify portal implementation strategies. METHODS: A qualitative descriptive approach was used. Semistructured interviews were conducted with 5 clinical nurse specialists. Two independent coders conducted an inductive content analysis of the transcribed interviews to generate codes describing patterns in the data to identify originating themes. RESULTS: The content analysis uncovered the following 4 themes: (1) implementation strategies, (2) nurse likelihood to recommend, (3) impact on nursing practice, and (4) perceived influence on patients. CONCLUSION: Direct care nurses may benefit from education and coaching on how to document in the record using patient-centered language that is understandable to patients who may be reading it. In addition, the use of patient portals should be designed to fit into nurses' existing clinical workflows. Finally, more research is needed to identify the benefits and unintended consequences of patient portals within a mental health context. PMID- 30299335 TI - A Best Practice Initiative to Optimize Transfer of Young Adults With Osteogenesis Imperfecta From Child to Adult Healthcare Services. AB - PURPOSE: The aims of this study were (1) to review the current body of knowledge on the transition experiences of adolescents with osteogenesis imperfecta (OI) and appraise the evidence available on transfer summary tools, (2) to develop guidelines for the successful transition of adolescents with OI from child to adult healthcare services, and (3) to create a transfer tool tailored to adolescents with OI. DESIGN AND METHODS: This knowledge synthesis study was overseen by an interprofessional expert task force at Shriners Hospitals for Children-Canada and entailed (1) review of the literature, (2) development of guidelines, and (3) creation of a tool. RESULTS: The tool was created from evidence compiled from case reports, clinical examples, and nonexperimental studies. CONCLUSION: The transfer tool proposes guidelines designed to facilitate a smooth transition from child to adult healthcare services. It also offers creation of a clinically meaningful, person-focused, OI transfer tool that may in turn help improve the transition experience for adolescents. This study significantly contributes to the dearth of literature on transition experiences in OI and on transfer tools in general. Future research is needed to evaluate the implementation and evaluation of the OI transfer tool in practice. PMID- 30299336 TI - Caring for the Body, Mind, and Spirit.

PMID- 30299338 TI - Biomarkers for Radiation Biodosimetry and Injury Assessment after Mixed-field (Neutron and Gamma) Radiation in the Mouse Total-body Irradiation Model. AB - The risk of potential radiation exposure scenarios that include detonation of nuclear weapons, terrorist attacks on nuclear reactors, and the use of conventional explosives to disperse radioactive substances has increased in recent years. The majority of radiation biodosimetry and countermeasure studies have been performed using photon radiation even though many exposure scenarios predict mixed-field (neutron and photon) radiation. Hence, there is a need to evaluate biomarkers and accurately determine exposure levels of mixed-field combinations of neutrons and photons for an individual. These biomarkers will be critical for biodosimetry triage, treatment, and follow-up visits with such individuals. We evaluated the utility of multiple blood biomarkers for early response assessment of radiation exposure using a mouse (B6D2F1, males and females) total-body irradiation model exposed to a mixed-field (neutrons and gamma rays) using the Armed Forces Radiobiology Research Institute's Mark F nuclear research reactor. Total-body irradiation was given as a single exposure over a dose range from 1.5 to 6 Gy, dose rates of 0.6 and 1.9 Gy min, and different proportions of neutrons and gammas: either (67% neutrons + 33% gammas) or (30% neutrons + 70% gammas). Blood was collected 1, 2, 4, and 7 d after total body irradiation. Radiation-responsive protein biomarkers were measured using the Meso Scale Diagnostics' high-throughput MULTI-ARRAY plate-format platform (QuickPlex 120 Imager) and enzyme-linked immunosorbent assay kits. Results demonstrate (1) dose- and time-dependent changes in fms-related tyrosine kinase 3 ligand, interleukins IL-5, IL-10, IL-12, and IL-18, granulocyte and granulocyte macrophage colony-stimulating factors, thrombopoietin, erythropoietin, acute phase proteins (serum amyloid A and lipopolysaccharide binding protein), surface plasma neutrophil (CD45) and lymphocyte (CD27) markers, ratio of CD45 to CD27, and procalcitonin; (2) dose- and time-dependent changes in blood cell counts (lymphocytes, neutrophils, platelets, red blood cells, and ratio of neutrophils to lymphocytes); (3) levels of IL-18, granulocyte and granulocyte-macrophage colony-stimulating factors, serum amyloid A, and procalcitonin were significantly higher in animals irradiated with 67% neutrons + 33% gammas compared to those irradiated with 30% neutrons + 70% gammas (p < 0.015), while no significant differences (p > 0.114) were observed in hematological biomarker counts; (4) exposure with 3-fold difference in dose rate (0.6 or 1.9 Gy min) revealed no significant differences in hematological and protein biomarker levels (p > 0.154); and (5) no significant differences in hematological and protein biomarker levels were observed in the sex-comparison study for any radiation dose at any time after exposure (p > 0.088). Results show that the dynamic changes in the levels of selected hematopoietic cytokines, organ-specific biomarkers, and acute phase protein biomarkers reflect the time course and severity of acute radiation syndrome and may function as prognostic indicators of acute radiation syndrome outcome. These studies supplement an ongoing effort to deliver U.S. Federal Drug Administration-approved biodosimetry capabilities, which assess mixed-field radiation exposure.

AB - Digital autoradiography with the ionizing radiation quantum imaging detector is used at the US Transuranium and Uranium Registries for visualizing the microdistribution of alpha particles from Am and quantifying the activity. The radionuclide spatial distribution was investigated within cortical and trabecular regions of bone samples from US Transuranium and Uranium Registries case 0846. Multiple specimens from the humerus proximal end, humerus proximal shaft, and clavicle acromial end were embedded in plastic, and 100-MUm-thick sections were taken and imaged using the ionizing radiation quantum imaging detector. The detector images were superimposed on the anatomical structure images to visualize Am distribution in cortical bone, trabecular bone, and trabecular spongiosa. Activity concentration ratios were used to characterize Am distribution within different bone regions. The trabecular-to-cortical bone and trabecular-spongiosa to-cortical bone activity concentration ratios were quantified in both humerus and clavicle. The ionizing radiation quantum imaging detector results were in agreement with those obtained from radiochemical analysis of the remaining bone specimens. The results were compared with International Commission on Radiological Protection default biokinetic model predictions. Digital autoradiography was proven to be an effective method for microscale heterogeneous distribution studies where traditional counting methods are impractical. PMID- 30299340 TI - Opioid Prescribing Practices of Orthopaedic Surgeons: Results of a National Survey. AB - INTRODUCTION: Opioids are widely used after orthopaedic procedures. Nonmedical opioid use is a growing public health issue. METHODS: An anonymous online survey was distributed by e-mail to the orthopaedic societies of all 50 states and several large private practices to assess practicing orthopaedic surgeons' opioid prescribing practices. RESULTS: A total of 555 orthopaedic surgeons practicing in 37 states responded. The most commonly prescribed opioid for both teenagers and adults was hydrocodone/acetaminophen. Of note, 42.3% reported that a patient they have prescribed opioids for developed an opioid dependency, whereas 35.3% do not believe that opioid use is a problem in their practice. Of note, 30.3% reported prescribing refills, and factors significantly associated with increased prescribing of refills included a greater number of years in practice (P < 0.001) and practicing in a suburban rather than an urban or rural environment (P = 0.03). CONCLUSION: Orthopaedic surgeons rarely prescribe any refills, tend to prescribe less opioids to teenagers than adults, and prescribe fairly uniformly for patients who are treated nonsurgically or undergo minor or arthroscopic surgery. They exhibit considerable variation in prescribing for fractures and major procedures. PMID- 30299341 TI - Effect of Obesity on Perioperative Complications, Hospital Costs, and Length of Stay in Patients With Open Ankle Fractures. AB - INTRODUCTION: The objective of this study was to examine the effect of obesity on perioperative complications and the cost of surgical management of open ankle fractures. METHODS: This study examined data from the National Inpatient Sample. The primary outcome variables assessed were occurrence of any complication, complication subtype, length of stay, and total hospital costs. RESULTS: Patients with obesity accounted for 10.1% (n = 8.972) of the total cohort. After adjusting for patient and hospital characteristics, patients with obesity exhibited higher odds of any complication, as well as longer length of stay and higher total costs. CONCLUSION: As our understanding of the association between complications and cost of managing open ankle fractures in patients with obesity improves, future research should strive to improve patient outcomes and decrease cost of care through efforts made to prevent complications in patients with obesity. PMID- 30299342 TI - Redundant Information Is Sometimes More Beneficial Than Spatial Information to Understand Speech in Noise. AB - OBJECTIVES: To establish a framework to unambiguously define and relate the different spatial effects in speech understanding: head shadow, redundancy, squelch, spatial release from masking (SRM), and so on. Next, to investigate the contribution of interaural time and level differences to these spatial effects in speech understanding and how this is influenced by the type of masking noise. DESIGN: In our framework, SRM is uniquely characterized as a linear combination of head shadow, binaural redundancy, and binaural squelch. The latter two terms are combined into one binaural term, which we define as binaural contrast: a benefit of interaural differences. In this way, SRM is a simple sum of a monaural and a binaural term. We used the framework to quantify these spatial effects in 10 listeners with normal hearing. The participants performed speech intelligibility tasks in different spatial setups. We used head-related transfer functions to manipulate the presence of interaural time and level differences. We used three spectrally matched masker types: stationary speech-weighted noise, a competing talker, and speech-weighted noise that was modulated with the broadband temporal envelope of the competing talker. RESULTS: We found that (1) binaural contrast was increased by interaural time differences, but reduced by interaural level differences, irrespective of masker type, and (2) large redundancy (the benefit of having identical information in two ears) could reduce binaural contrast and thus also reduce SRM. CONCLUSIONS: Our framework yielded new insights in binaural processing in speech intelligibility. First, interaural level differences disturb speech intelligibility in realistic listening conditions. Therefore, to optimize speech intelligibility in hearing aids, it is more beneficial to improve monaural signal-to-noise ratios rather than to preserve interaural level differences. Second, although redundancy is mostly ignored when considering spatial hearing, it might explain reduced SRM in some cases. PMID- 30299343 TI - Factors Affecting Sound-Source Localization in Children With Simultaneous or Sequential Bilateral Cochlear Implants. AB - OBJECTIVES: The study aimed to determine the effect of interimplant interval and onset of profound deafness on sound localization in children with bilateral cochlear implants, controlling for cochlear implant manufacturer, age, and time since second implant. DESIGN: The authors conducted a retrospective, observational study using routinely collected clinical data. Participants were 127 bilaterally implanted children aged 4 years or older, tested at least 12 mo post- second implant. Children used implants made by one of three manufacturers. Sixty-five children were simultaneously implanted, of whom 43% were congenitally, bilaterally profoundly deaf at 2 and 4 kHz and 57% had acquired or progressive hearing loss. Sixty-two were implanted sequentially (median interimplant interval = 58 mo, range 3-143 mo) of whom 77% had congenital and 23% acquired or progressive bilateral profound deafness at 2 and 4 kHz. Children participated in a sound-source localization test with stimuli presented in a random order from five loudspeakers at -60, -30, 0, +30, and +60 degrees azimuth. Stimuli were prerecorded female voices at randomly roved levels from 65 to 75 dB(A). Root mean square (RMS) errors were calculated. Localization data were analyzed via multivariable linear regression models, one applied to the whole group and the other to just the simultaneously? implanted children. RESULTS: Mean RMS error was 25.4 degrees (SD = 12.5 degrees) with results ranging from perfect accuracy to chance level (0-62.7 degrees RMS error). Compared with simultaneous implantation, an interimplant interval was associated with worse localization by 1.7 degrees RMS error per year (p < 0.001). Compared with congenital deafness, each year with hearing thresholds better than 90 dB HL at 2 and 4 kHz bilaterally before implantation led to more accurate localization by 1.3 degrees RMS error (p < 0.005). Every year post-second implant led to better accuracy by 1.6 degrees RMS error (p < 0.05). Med-El was associated with more accurate localization than Cochlear by 5.8 degrees RMS error (p < 0.01) and with more accurate localization than Advanced Bionics by 9.2 degrees RMS error (p < 0.05). CONCLUSIONS: Interimplant interval and congenital profound hearing loss both led to worse accuracy in sound-source localization for children using bilateral cochlear implants. Interimplant delay should therefore be minimized for children with bilateral profound hearing loss. Children presenting with acquired or progressive hearing loss can be expected to localize better via bilateral cochlear implants than their congenitally deaf peers. PMID- 30299344 TI - Effects of induction of labor prior to post-term in low-risk pregnancies: a systematic review. AB - OBJECTIVE: The objective of this review was to identify, assess and synthesize the best available evidence on the effects of induction prior to post-term on the mother and fetus. Maternal and fetal outcomes after routine labor induction in low-risk pregnancies at 41+0 to 41+6 gestational weeks (prior to post-term) were compared to routine labor induction at 42+0 to 42+6 gestational weeks (post term). INTRODUCTION: Induction of labor when a pregnancy exceeds 14 days past the estimated due date has long been used as an intervention to prevent adverse fetal and maternal outcomes. Over the last decade, clinical procedures have changed in many countries towards an earlier time for induction. A shift towards earlier inductions may lead to 15-20% more inductions. Given the fact that induction as an intervention can cause harm to both mother and child, it is essential to ensure that the benefits of the change in clinical practice outweigh the harms. INCLUSION CRITERIA: This review included studies with participants with expected low-risk deliveries, where both fetus and mother were considered healthy at inclusion and with no known risks besides the potential risk of the ongoing pregnancy. Included studies evaluated induction at 41+1-6 gestational weeks compared to 42+1-6 gestational weeks. Randomized control trials (RCTs) (n = 2), quasi-experimental trials (n = 2), and cohort studies (n = 3) were included. The primary outcomes of interest were cesarean section, instrumental vaginal delivery, low Apgar score (<= 7/5 min.), and low pH (< 7.10). Secondary outcomes included additional indicators of fetal or maternal wellbeing related to prolonged pregnancy or induction. METHODS: The following information sources were searched for published and unpublished studies: PubMed, CINAHL, Embase, Scopus, Swemed+, POPLINE; Cochrane, TRIP; Current Controlled Trials; Web of Science, and, for gray literature: MedNar; Google Scholar, ProQuest Nursing & Allied Health Source, and guidelines from Royal College of Obstetricians and Gynaecologists and The American College of Obstetricians and Gynecologists, according to the published protocol. In addition, OpenGrey and guidelines from National Institute for Health and Care Excellence, The World Health Organization, and The Society of Obstetricians and Gynaecologists of Canada were sought. Included papers were assessed by all three reviewers independently using the Joanna Briggs Institute System for the Unified Management, Assessment and Review of Information (JBI SUMARI). The standardized data extraction tool from JBI SUMARI was used. Data were pooled in a statistical meta-analysis model using RevMan 5, when the criteria for meta-analysis were met. Non-pooled results were presented separately. RESULTS: Induction at 41+0-6 gestational weeks compared to 42+0-6 gestational weeks was found to be associated with an increased risk of overall cesarean section (relative risk [RR] = 1.11, 95% confidence interval [CI] 1.09 1.14), cesarean section due to failure to progress (RR = 1.43, 95% CI 1.01-2.01), chorioamnionitis (RR = 1.13, 95% CI 1.05-1.21), labor dystocia (RR = 1.29, 95% CI 1.22-1.37), precipitate labor (RR = 2.75, 95% CI 1.45-5.2), uterine rupture (RR = 1.97, 95% CI 1.54-2.52), pH < 7.10 (RR = 1.9, 95% CI 1.48-2.43), and a decreased risk of oligohydramnios (RR = 0.4, 95% CI 0.24-0.67) and meconium stained amniotic fluid (RR = 0.82, 95% CI 0.75-0.91). Data lacked statistical power to draw conclusions on perinatal death. No differences were seen for postpartum hemorrhage, shoulder dystocia, meconium aspiration, 5-minute Apgar score < 7, or admission to neonatal intensive care unit. A policy of awaiting spontaneous onset of labor until 42+0-6 gestational weeks showed, that approximately 70% went into spontaneous labor. CONCLUSIONS: Induction prior to post-term was associated with few beneficial outcomes and several adverse outcomes. This draws attention to possible iatrogenic effects affecting large numbers of low-risk women in contemporary maternity care. According to The World Health Organization, expected benefits from a medical intervention must outweigh potential harms. Hence, our results do not support the widespread use of routine induction prior to post-term (41+0-6 gestational weeks).This is an open access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30299345 TI - Student and Faculty Experiences in the Flipped Learning Environment in Undergraduate Nursing. AB - AIM: The aim of the study was to describe student and faculty experiences in the flipped learning environment. BACKGROUND: Studies of flipped instruction in science, technology, engineering, and mathematics reveal improvements in student performance. There is limited research related to student and faculty experiences in the learning environment. METHOD: This study utilized a multiple-case study research design with two undergraduate nursing courses at two institutions. RESULTS: Student participants in Case A felt the implementation of flipped learning reflected the pillars of flipped learning more than Case B participants. The strategies used to implement flipped learning in the two cases were different as were student experiences. CONCLUSION: Three conclusions resulted from the study: flipped learning results in a shift in the student role that requires additional instructor support, instructors would benefit from guidance in the form of best practices, and nurse educators can use flipped learning to better meet the learning needs of their students. PMID- 30299346 TI - Impact of an HIV Care Coordination Program on Durable Viral Suppression. AB - BACKGROUND: To assess long-term effectiveness of an intensive and comprehensive Ryan White Part A-funded HIV Care Coordination Program (CCP) recruiting people living with HIV (PLWH) with a history of suboptimal HIV care outcomes. METHODS: We merged programmatic data on CCP clients with surveillance data on all adults diagnosed with HIV. Using propensity score matching, we identified a contemporaneous, non-CCP exposed comparison group. Durable viral suppression (DVS) was defined as regular VL monitoring and all VLs <=200 copies/mL in months 13-36 of follow-up. RESULTS: Ninety percent of the combined cohort (N=12,414) had >=1 VL<=200 during the follow-up period (December 1, 2009 to March 31, 2016), and nearly all had routine VL monitoring, but only 36.8% had DVS. While DVS did not differ overall (relative risk[RR]: 0.99, 95%CI: 0.95-1.03), CCP clients without any VL suppression in the 12 months pre-enrollment showed higher DVS versus 'usual care' recipients (21.3% versus 18.4%; RR: 1.16, 95%CI: 1.04-1.29). CONCLUSIONS: Enrollment in an intensive intervention modestly improved DVS among those unsuppressed prior to CCP enrollment. This program shows promise for meeting treatment-as-prevention goals and advancing progress along the HIV care continuum, if people without evidence of VLS are prioritized for CCP enrollment over those with recent evidence of VLS. Low overall DVS (<40%) levels underscore a need for focused adherence-maintenance interventions, in a context of high treatment access. PMID- 30299348 TI - Burkitt Lymphoma Presenting With Intracardiac Mass and Tumor Thrombosis in the Anterior Mediastinum With Literature Review. AB - Burkitt lymphoma manifesting as an intracardiac mass is a rare entity. This report describes the case of a 10-year-old boy who presented with an intracardiac mass and tumor thrombosis in the anterior mediastinum that proved to be Burkitt lymphoma. The LMB-96 chemotherapy protocol was given and at the end of the treatment there was still residual mass. A biopsy was performed and the pathology revealed thymus tissue. The patient has been in complete remission for 3 months. Burkitt lymphoma has a short doubling time and an intracardiac lesion can become life threatening. Early recognition and prompt treatment are crucial in achieving optimal outcomes. PMID- 30299347 TI - The Association of Fibroblast Growth Factor-23 (FGF-23) with Incident Frailty in HIV-Infected and -Uninfected Individuals. AB - BACKGROUND: In the Multicenter AIDS Cohort Study, we examined whether fibroblast growth factor-23 (FGF-23), a bone-derived phosphaturic hormone involved in bone metabolism, is associated with incident frailty. Further, we examined whether this association differs by HIV serostatus and race. METHODS: Of 715 men assessed for frailty and selected for FGF-23 measurements using stored blood samples (2007 2011), 512 men were non-frail at/prior to the baseline visit. Frailty was defined by the presence of >=3 of the following on two consecutive 6-month visits within 1 year: unintentional weight loss >=10 pounds, weakness, slowness, low energy and low physical activity. We determined the association of FGF-23 levels with incident frailty using proportional hazards models adjusting for sociodemographics, co-morbidities and kidney function. RESULTS: Sixty-five percent were HIV-infected; 29% were black. Median baseline FGF-23 levels were lower in HIV-infected versus HIV-uninfected men (33.7 vs. 39.9 rU/mL, p=0.006) but similar by race. During a median follow-up of 6.6 years, 32 men developed frailty; they had higher baseline FGF-23 levels versus men who remained non-frail (45 vs. 36 rU/mL, p=0.02). FGF-23 (per doubling) was associated with a 1.63-fold risk of frailty (95%CI:1.19, 2.23); results did not differ by HIV serostatus. Conversely, FGF-23 was associated with a 2.72-fold risk of frailty among blacks (95%CI:1.51, 4.91) but had minimal association among non-blacks (HR=1.26, 95%CI:0.77, 2.05; p-interaction=0.024). CONCLUSION: Among men with or at-risk for HIV infection, higher FGF-23 was associated with greater risk of frailty, particularly in blacks. The mechanisms by which FGF-23 may contribute to frailty warrant further study. PMID- 30299349 TI - Not All Pediatric Bladder Masses are Rhabdomyosarcoma: Report of a Rare Case With Review of the Literature. AB - Leiomyoma of the urinary bladder in the pediatric age group is one of the rarest tumors with only 2 case reports in the English literature. Rhabdomyosarcoma is the commonest tumor at this site in this age group. It needs to be distinguished from rhabdomyosarcoma by histomorphology for appropriate treatment and management. We report the third case of urinary bladder leiomyoma arising in a 6 year-old boy with a short review of the literature. PMID- 30299351 TI - Successful Treatment of an Adolescent Male With Severe Refractory Evans Syndrome Using Bortezomib-based Therapy. AB - Evans syndrome is defined by bilineal autoimmune cytopenia, typically coombs positive hemolytic anemia and thrombocytopenia. Corticosteroids are the mainstay of treatment, with rituximab and/or mycophenolate mofetil often used in steroid refractory cases. However, no treatment methodology has ever evaluated by a randomized clinical trial. We present a 15-year-old boy with Evans syndrome and common variable immunodeficiency who experienced a severe, refractory flare 16 months postsplenectomy. After failing to respond to multiple other agents, he achieved a durable response to a bortezomib-based regimen. Bortezomib may be a reasonable second or third line option, especially before high-morbidity therapies such as splenectomy or stem cell transplantation. PMID- 30299350 TI - Gray Zone Lymphoma Arising in the Neck of a Teenager With a Germline Mutation in TP53. AB - Gray zone lymphoma is an aggressive disease for which appropriate management is still debated. We report a 15-year-old girl with a cervical mass, an enlarged ipsilateral tonsil, and anemia. Both sites showed hypermetabolism on F18-FG positron emission tomography/CT. Surgical resection was diagnostic of Epstein Barr virus-negative gray zone lymphoma cervical and tonsillar involvement. No abnormality was found in cytogenetic analysis on tumor cells. However, exome sequencing in peripheral blood DNA revealed a germline mutation in TP53. Complete response was achieved after surgery and 6 cycles of rituximab with dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin regimen.

PMID- 30299353 TI - Multidrug-resistant Gram-negative infection in solid organ transplant recipients: implications for outcome and treatment. AB - PURPOSE OF REVIEW: Solid organ transplantation (SOT) is the best therapeutic option for both acute and chronic end-stage diseases. The development of more potent and safer immunosuppressants and the improvement of prophylactic practices have significantly diminished the morbidity and mortality associated with rejection and opportunistic infections. However, infections produced by multidrug resistant (MDR) Gram-negative bacilli (GNB) have recently emerged as a significant threat. RECENT FINDINGS: The Spanish Society of Transplantation (SET), the Group for Study of Infection in Transplantation of the Spanish Society of Infectious Diseases and Clinical Microbiology (GESITRA-SEIMC) and the Spanish Network for Research in Infectious Diseases (REIPI) have recently published their recommendations concerning the management of MDR GNB infections in SOT recipients. We review this guideline, and also the most recent available evidence, focusing on donor-derived infections, colonized recipients and therapeutic approaches. SUMMARY: Overall, donor and recipient colonization is associated with an increased risk of infection by MDR GNB, although none of these circumstances constitutes an absolute contraindication to transplantation. SOT recipients with risk factors for MDR GNB infection should receive an empirical treatment which includes potentially active antibiotics. Targeted therapy should be adjusted according to antimicrobial susceptibility testing and severity of infection. PMID- 30299354 TI - How to optimize antibiotic pharmacokinetic/pharmacodynamics for Gram-negative infections in critically ill patients. AB - PURPOSE OF REVIEW: Optimized antibiotic dosing regimens improve survival rates in critically ill patients. However, dose optimization is challenging because of fluctuating antibiotic pharmacokinetics both between patients and within a single patient. This study reviews the pharmacokinetic changes that occur in critically ill patients, along with the pharmacodynamics and toxicodynamics of antibiotics commonly used for the treatment of Gram-negative bacterial infections to formulate a recommendation for antibiotic dosing at the bedside. RECENT FINDINGS: Recent studies highlight that critically ill patients do not achieve therapeutic antibiotic exposures with standard antibiotic dosing. Although dose increases are required, the method of administration, such as the use of beta-lactam antibiotic continuous infusions and nebulized aminoglycoside administration, may improve efficacy and limit toxicity. In addition, the increased availability of therapeutic drug monitoring and antibiotic dosing software allow the formulation of individualized dosing regimens at the bedside. SUMMARY: When prescribing antibiotic doses, the clinician should consider antibiotic pharmacokinetic and pharmacodynamic principles. Before initiating high-dose antibiotic therapy, therapeutic drug monitoring may be considered to assist the clinician to optimize antibiotic treatment and minimize potential toxicity. PMID- 30299355 TI - Hepatitis B virus and hepatitis C virus infection in immunocompromised patients. AB - PURPOSE OF REVIEW: To provide an update on recent studies of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in cancer patients with an emphasis on viral reactivation after cancer treatment, new antiviral therapies, and safety concerns. RECENT FINDINGS: The diagnostic criteria for HBV reactivation in patients receiving cancer therapy were revised in 2018. HBV reactivation in these patients is preventable, even with the use of new cancer therapies. HCV reactivation also has been reported in cancer patients, particularly those with hematologic malignancies, and is not a virologic condition usually associated with poor outcome. Prophylaxis to prevent HCV reactivation is not recommended because therapy with direct-acting antivirals eradicates the infection in the majority of cancer patients. SUMMARY: Cancer patients with HBV or HCV infection are at risk for viral reactivation, with many similarities between these two infections. Patients at high risk for reactivation will benefit significantly from taking oral antivirals, which will reduce the risk of HBV reactivation or prevent development of HCV reactivation following its virologic cure. PMID- 30299356 TI - Neuraminidase inhibitor resistance in influenza: a clinical perspective. AB - PURPOSE OF REVIEW: Neuraminidase inhibitors (NAIs), including oseltamivir, zanamivir, and peramivir, is the main class of antiviral available for clinical use. As such, development of resistance toward these agents is of great clinical and public health concern. RECENT FINDINGS: At present, NAI resistance remains uncommon among the circulating viruses (oseltamivir <3.5%, zanamivir <1%). Resistance risk is slightly higher in A(H1N1) than A(H3N2) and B viruses. Resistance may emerge during drug exposure, particularly among young children (<5 years), the immunocompromised, and individuals receiving prophylactic regimens. H275Y A(H1N1) variant, showing high-level oseltamivir resistance, is capable of causing outbreaks. R294K A(H7N9) variant shows reduced inhibition across NAIs. Multi-NAI resistance has been reported in the immunocompromised. SUMMARY: These findings highlight the importance of continuous surveillance, and assessment of viral fitness and transmissibility of resistant virus strains. Detection can be challenging, especially in a mix of resistant and wild-type viruses. Recent advances in molecular techniques (e.g. targeted mutation PCR, iART, ddPCR, pyrosequencing, next-generation sequencing) have improved detection and our understanding of viral dynamics. Treatment options available for oseltamivir resistant viruses are limited, and susceptibility testing of other NAIs may be required, but non-NAI antivirals (e.g. polymerase inhibitors) that are active against these resistant viruses are in late-stage clinical development. PMID- 30299357 TI - Combination versus monotherapy for the treatment of infections due to carbapenem resistant Enterobacteriaceae. AB - PURPOSE OF REVIEW: Combination therapy is a common strategy for treatment of multidrug resistant infections. Despite the strong twin rationales of improving efficacy and reducing resistance development, the evidence supporting this strategy remains controversial. The aims of this review are to assess the most recent studies supporting the use of combination therapy for treating infections because of carbapenem-resistant Enterobacteriaceae (CRE) and to highlight relevant areas for further research. RECENT FINDINGS: Evidence supporting the use of combination therapy for the treatment of CRE remains limited to in-vitro experiments and observational studies with considerable risk of bias. Very few antibiotic combinations have been tested in well designed randomized controlled trials, making it difficult to draw general conclusions for clinical practice. SUMMARY: Further studies are urgently needed to test the most promising synergistic combinations. New drugs potentially active against CRE should also to be tested in studies with adequate sample size and truly representative of the general patient population. PMID- 30299358 TI - Current management of Gram-negative septic shock. AB - PURPOSE OF REVIEW: Sepsis is a common condition in critically ill patients and associated with high morbidity and mortality. Sepsis is the result of infection by many potential pathogens, including Gram-negative bacteria. There are no specific antisepsis therapies and management relies largely on infection control and organ support, including hemodynamic stabilization. We discuss these key aspects and briefly mention potential immunomodulatory strategies. RECENT FINDINGS: New aspects of sepsis management include the realization that early treatment is important and that fluids and vasopressor agents should be administered simultaneously to insure rapid restoration of an adequate perfusion pressure to limit development and worsening of organ dysfunction. New immunomodulatory therapies, both suppressive and stimulatory, are being tested. SUMMARY: Early diagnosis enabling rapid treatment can optimize outcomes. The multiple components of adequate sepsis management necessitate a team approach. PMID- 30299359 TI - The ideal patient profile for new beta-lactam/beta-lactamase inhibitors. AB - PURPOSE OF REVIEW: The worldwide spread of extended-spectrum beta-lactamase (ESBL)-producing bacteria, the overuse of carbapenems, the emergence of carbapenemase-producing organisms and the growing importance of multidrug resistant and/or extended drug-resistant strains have totally changed prescribers' habits, leading to very few treatment options in many cases. Beta lactam/beta-lactamase inhibitor (BLBLI) combinations should be considered as an alternative to carbapenems for treating ESBL-producing bacteria and Pseudomonas aeruginosa infections. The purpose of this study was to provide insight concerning the patients who would constitute ideal candidates to receive these new BLBLI combinations. RECENT FINDINGS: Ceftolozane/tazobactam and ceftazidime/avibactam are the first drugs constituting the use of new beta lactamase inhibitors. Ceftolozane/tazobactam is the drug of choice for treating MDR/XDR P. aeruginosa infections. Ceftazidime/avibactam is the best drug available for treating KPC and OXA-48 carbapenemase-producing Enterobacteriaceae. Ceftolozane/tazobactam and ceftazidime/avibactam are both carbapenem-sparing agents for treating ESBL-producing Enterobacteriaceae. The role of carbapenem/inhibitors remains to be clarified. SUMMARY: Each BLBLI combination has distinctive specificities and limitations that need to be investigated cautiously. Randomized trials will play a key role in defining the best strategies. Infection control measures and prompt diagnosis remain fundamental to prevent dissemination of MDR pathogens in healthcare settings and to optimize early antimicrobial treatment. PMID- 30299360 TI - Polyclonal and monoclonal antibodies for the treatment of influenza. AB - PURPOSE OF REVIEW: This review summarizes past and ongoing efforts for using polyclonal and monoclonal antibodies for the treatment of influenza, and is focused on products that have entered clinical trials. RECENT FINDINGS: At least three polyclonal and eight monoclonal antibody products have been tested in clinical trials for the treatment of influenza. Considered across the two classes of therapeutics, these products appear to be safe and well tolerated. However, the efficacy results have been mixed and inconclusive. To date, no products have consistently shown superiority to currently available antivirals. SUMMARY: No products within these two classes have been licensed, and several products appear to have stopped further clinical development. There are several ongoing studies that are anticipated to be completed or reported in the next 1-2 years which will be critical for understanding the value of polyclonal and monoclonal antibodies in the treatment of influenza. PMID- 30299361 TI - Invasive fungal disease and cytomegalovirus infection: is there an association? AB - PURPOSE OF REVIEW: Invasive fungal disease (IFD) and cytomegalovirus (CMV) infections occur frequently, either concomitantly or sequentially in immune compromised hosts. Although there is extensive knowledge of the risk factors for these infections as single entities, the inter-relationship between opportunistic fungii and CMV has not been comprehensively explored. RECENT FINDINGS: Both solid organ and stem cell transplant recipients who develop CMV invasive organ disease are at an increased risk of developing IFD, particularly aspergillosis and Pneumocystis pneumonia (PCP). Moreover, CMV viremia and recipient CMV serostatus also increased the risk of both early and late-onset IFD. Treatment-related factors, such as ganciclovir-induced neutropenia and host genetic Toll-like receptor (TLR) polymorphisms are likely to be contributory. Less is known about the relationship between CMV and IFD outside transplantation, such as in patients with hematological cancers or other chronic immunosuppressive conditions. Finally, few studies report on the relationship between CMV-specific treatments or the viral/antigen kinetics and its influence on IFD management. SUMMARY: CMV infection is associated with increased risk of IFD in posttransplant recipients because of a number of overlapping and virus-specific risk factors. Better understanding of how CMV virus, its related treatment, CMV-induced immunosuppression and host genetic factors impact on IFD is warranted. PMID- 30299362 TI - Antifungal stewardship: developments in the field. AB - PURPOSE OF REVIEW: To outline key drivers and components of antifungal stewardship (AFS) programmes, the evidence for specific interventions, and methods to assess performance of programmes. RECENT FINDINGS: Recent developments in antifungal resistance and breakthrough invasive fungal diseases have increased the urgency for effective AFS. In practice, however, few hospitals have dedicated AFS programmes. To date, AFS programmes have centred around the provision of expert bedside reviews and have reduced costs and consumption of antifungal agents. Incorporating tools such as fungal diagnostics and therapeutic drug monitoring into AFS programme models is recommended. However, the application and impact of these tools in this context have not been adequately assessed. The effectiveness of AFS programmes has been measured in multiple ways but a standardized method of evaluation remains elusive. Few studies have explored the impact of AFS interventions on patient outcomes. SUMMARY: The uptake of formal AFS programmes has been slow. New initiatives integrating AFS tools in programmes, and measuring the impacts on patient outcomes are required given such data are not readily available. A comprehensive approach to evaluate AFS programmes by correlating the quantity and quality of antifungal prescribing with impacts on patient outcomes is needed. Consensus definitions for core AFS metrics are required to benchmark performance and are essential to the resourcing and sustainability of these programmes. PMID- 30299363 TI - Whipple's disease and Tropheryma whipplei infections: when to suspect them and how to diagnose and treat them. AB - PURPOSE OF REVIEW: The delay between first clinical signs and diagnosis of Whipple's disease and Tropheryma whipplei infections is more than 6 years, and relapses are frequently observed, resulting in a need for clinicians to be aware of this infection. RECENT FINDINGS: 18 FDG-PET is useful in the diagnosis and the follow-up of patients (particularly in case of neurological involvement). Histological involvement remains the goldstandard for classic Whipple's disease diagnosis. PCR performed on biopsies of fluid is the main tool for the diagnosis of localized chronic infections. PCR performed on urine samples should become an important role of noninvasive diagnostic strategies, while T. whipplei PCR performed on saliva and stool lack specificity. Because of lifetime susceptibility to T. whipplei and in-vitro susceptibility data, a 1-year course of doxycycline and hydroxychloroquine followed by a lifelong treatment by doxycycline is recommended for Whipple's disease, localized endocarditis and encephalitis. SUMMARY: Clinical involvement of the different T. whipplei infections is well described, as well as the treatment of Whipple's disease, endocarditis and encephalitis. The place of PCR performed on urine remains to be clarified for diagnosis of localized T. whipplei infections and acute infections as well as the optimal treatment for arthritis and acute infections. PMID- 30299364 TI - Rational approach in the management of Pseudomonas aeruginosa infections. AB - PURPOSE OF REVIEW: This review details the management of Pseudomonas aeruginosa infections covering both current and future treatment options that are and may be available for the clinicians. RECENT FINDINGS: Pseudomonas aeruginosa infections are a great concern in hospital-acquired infections with very limited therapeutic options. The increasing antibiotic resistance has led to a need for different treatment choices that range from the use of new antibiotics to new nonantibiotic alternative agents to kill or disarm the pathogen. SUMMARY: New molecules such as ceftolozane-tazobactam, ceftazidime-avibactam, and imipenem-relebactam have shown an adequate activity against P. aeruginosa, especially against multidrug resistance strains. Other nonantibiotic alternative treatments, such as antibodies, bacteriocins or phage therapy, have shown promising results, but future clinical studies are needed.

PMID- 30299367 TI - Invasive pulmonary aspergillosis complicating severe influenza: epidemiology, diagnosis and treatment. AB - PURPOSE OF REVIEW: Bacterial super-infection of critically ill influenza patients is well known, but in recent years, more and more reports describe invasive aspergillosis as a frequent complication as well. This review summarizes the available literature on the association of invasive pulmonary aspergillosis (IPA) with severe influenza [influenza-associated aspergillosis (IAA)], including epidemiology, diagnostic approaches and treatment options. RECENT FINDINGS: Though IPA typically develops in immunodeficient patients, non-classically immunocompromised patients such as critically ill influenza patients are at high risk for IPA as well. The morbidity and mortality of IPA in these patients is high, and in the majority of them, the onset occurs early after ICU admission. At present, standard of care (SOC) consists of close follow-up of these critically ill influenza patients with high diagnostic awareness for IPA. As soon as there is clinical, mycological or radiological suspicion for IAA, antifungal azole based therapy (e.g. voriconazole) is initiated, in combination with therapeutic drug monitoring (TDM). Antifungal treatment regimens should reflect local epidemiology of azole-resistant Aspergillus species and should be adjusted to clinical evolution. TDM is necessary as azoles like voriconazole are characterized by nonlinear pharmacokinetics, especially in critically ill patients. SUMMARY: In light of the frequency, morbidity and mortality associated with influenza-associated aspergillosis in the ICU, a high awareness of the diagnosis and prompt initiation of antifungal therapy is required. Further studies are needed to evaluate the incidence of IAA in a prospective multicentric manner, to elucidate contributing host-derived factors to the pathogenesis of this super-infection, to further delineate the population at risk, and to identify the preferred diagnostic and management strategy, and also the role of prophylaxis.

PMID- 30299369 TI - Fuchs Endothelial Corneal Dystrophy Through the Prism of Oxidative Stress. AB - The corneal endothelium (CE) is vital for maintaining the water balance and clarity of the cornea. The CE is a cell layer that is particularly susceptible to aging because of its postmitotic arrest, high metabolic activity involving pumping of ions, and lifelong exposure to ultraviolet light. Despite gradual age related cell loss, a sufficient number of CE cells are preserved during the lifespan of an individual. However, in conditions such as Fuchs endothelial corneal dystrophy (FECD), permanent loss of CE cells leads to corneal edema and loss of vision requiring corneal transplantation. FECD is a genetic and oxidative stress disorder manifested by abnormal cell-matrix interactions and expedited cellular aging culminating in cellular death. Because the endothelium has minimal replicative capacity in vivo and an inability to replace its genome, it is particularly prone to cumulative DNA damage acquired throughout life. In FECD, the underlying genetic defects make the CE genome even more vulnerable to this damage, to the point of causing mitochondrial dysfunction, mitochondrial membrane potential loss, and excessive mitophagy activation. Endogenous and exogenous intracellular stressors alter the synthetic footprint of CE cells, leading to endothelial-mesenchymal transition and secretion of aberrant extracellular matrix (in the form of guttae), resembling scar formation in other organs. In turn, the guttae or endothelial scars contribute to a vicious cycle of FECD pathogenesis and, by further inducing endothelial-mesenchymal transition and oxidant antioxidant imbalance, perpetuate the molecular changes of the degenerating endothelium. PMID- 30299370 TI - Preganglionic Parasympathetic Denervation Rabbit Model for Innervation Studies. AB - PURPOSE: Tear secretion from the main lacrimal gland (LG) is mainly regulated by parasympathetic nerves. We performed several innervation studies to investigate lacrimation. METHODS: In male rabbits, we performed a retrograde dye-tracing study of LG innervation, evaluated preganglionic parasympathetic denervation, and administered glial cell-derived neurotrophic factor (GDNF) in the surgical area after parasympathetic denervation. RESULTS: Accumulation of fluorescent dye was observed in the pterygopalatine ganglion cells on the same side as the dye injection into the main LG. Fewer stained cells were observed in the cervical and trigeminal ganglia. After parasympathetic denervation surgery, tear secretion was decreased, and fluorescein and rose bengal staining scores were increased at day 1 after surgery and remained increased for 3 months on the denervated side only. Most of the effects in rabbits with parasympathetic denervation were not recovered by administration of GDNF. CONCLUSIONS: The main LG is primarily innervated by parasympathetic nerves to stimulate tear secretion. After preganglionic parasympathetic denervation, lacrimation was decreased, resulting in dry eyes, and this was maintained for at least 3 months. Administration of GDNF only minimally altered the effects of denervation. PMID- 30299372 TI - Simulating Cultural Competence. PMID- 30299371 TI - Detection of IDH1 and IDH2 Mutation in Formalin-fixed Paraffin-embedded Gliomas Using Allele-specific COLD-PCR and Probe Melting Curve Analysis. AB - Many tumors, especially gliomas, contain an isocitrate dehydrogenase (IDH) mutation that can be used for clinical diagnosis and prognosis. Our study aimed to develop a new reliable detection assay for IDH1 and IDH2 mutations for clinical diagnosis based on the allele-specific (AS) coamplification with lower denaturing-polymerase chain reaction (COLD-PCR) and probe melting curve analysis (PMCA). The method includes 3 elements allowing for the sensitive detection of low-abundance mutations: (1) PCR amplification of the target fragments with AS primers; (2) COLD-PCR; and (3) PMCA for differentiating the different mutations after amplification. We conducted a blinded study with 45 paraffin-embedded gliomas specimens and 13 fresh specimens screened for IDH mutations using Sanger sequencing. Concordance between the results of our AS-COLD-PCR/PMCA assay and Sanger sequencing was 100%. Our assay appeared to be superior to direct sequencing with a much higher sensitivity of 0.4% mutations. In summary, our assay is a cost-effective, convenient, and sensitive method for detecting IDH mutations and could be applied in the clinical setting to assess small brain biopsies.

PMID- 30299374 TI - Perfusion of Porcine Kidneys with Macromolecular Heparin Reduces Early Ischemia Reperfusion Injury. AB - BACKGROUND: Previously we have been able to demonstrate the possibility of coating the inner surface of the renal arteries in porcine kidneys with a heparin conjugate during hypothermic machine perfusion (HMP). The purpose of this study was to assess the efficacy of this treatment in reducing early ischemia reperfusion injury. METHOD: Brain death was induced in male landrace pigs by stepwise volume expansion of an epidural balloon catheter until negative cerebral perfusion pressure was obtained. Both kidneys (matched pairs; n=6+6) were preserved for 20 hours by HMP during which 50 mg heparin conjugate was added to 1 of the HMP systems (treated group). A customized ex vivo normothermic oxygenated perfusion (NP) system with added exogenous creatinine was used to evaluate early kidney function. Blood, urine and histological samples were collected during the subsequent 3 hours of NP. RESULTS: Kidney weight was lower at the end of NP (p=0.017) in the treated group compared to control kidneys. The rate of decline in creatinine level was faster (p=0.024), total urinary volume was higher (p=0.031) and the level of urine neutrophil gelatinase-associated lipocalin (NGAL) was lower (p=0.031) in the treated group. Histologically, less tubular changes were seen (p=0.046). During NP intrarenal resistance remained lower (p<0.0001) in the treated group. CONCLUSIONS: Perfusion of porcine kidneys with heparin conjugate during HMP reduces preservation injury and improves organ function shortly after reperfusion. No increased risk of bleeding was seen in this setup. This protective strategy may potentially improve the quality of transplanted kidneys in the clinical setting. PMID- 30299376 TI - Words matter.

PMID- 30299378 TI - Delay in Hip Fracture Surgery Prolongs Postoperative Hospital Length of Stay but Does Not Adversely Affect Outcomes at 30 Days. AB - OBJECTIVES: To evaluate the association between the timing of hip fracture surgery with postoperative length of stay and outcomes. DESIGN: Retrospective review using the American College of Surgeons National Surgical Quality Improvement Program database. SETTING: National inquiry database incorporating 140 academic and private medical centers. PATIENTS: Seventeen thousand four hundred fifty-nine patients who underwent surgery for a hip fracture between 2006 and 2013 were identified from the National Surgical Quality Improvement Program database. INTERVENTION: Surgical management of hip fractures was performed at the discretion of participating surgeons. OUTCOME MEASURE: Thirty-day outcomes including postoperative length of stay, readmission rates, reoperation rates, complications, and mortality rates. RESULTS: Of the 17,459 patients, 4107 (23.5%) were operated on within 24 hours, 8740 (50.1%) within 24-48 hours, and 4612 (26.4%) more than 48 hours after hospital admission. Increased time to surgery was associated with longer postoperative hospital length of stay. Prolonged time to surgery did not adversely affect postoperative outcomes. CONCLUSIONS: Although a delay in the management of hip fractures is associated with an increase in postoperative hospital length of stay, 30-day postoperative outcomes are not adversely affected in patients undergoing hip fracture fixation.

PMID- 30299379 TI - Intraoperative Cone Beam Tomography and Navigation for Displaced Acetabular Fractures: A Comparative Study. AB - OBJECTIVES: To evaluate the accuracy of reduction of the acetabular articular surface using an intraoperative computed tomography scanner (O-Arm) and screw navigation compared with a classical open technique. DESIGN: Prospective matched cohort study. SETTING: Tertiary referral center. PATIENTS/PARTICIPANTS: Adult patients with acute acetabular fractures were included in the study. All patients were treated by 2 senior surgeons using intraoperative imaging and screw navigation. MAIN OUTCOME MEASUREMENTS: The primary outcome measure was articular reduction. Secondary outcomes were radiation dosage, operative variables [operative time, time for image acquisition, intraoperative bleeding (cell saver), number of surgical plates, and number of screws], and postoperative variables (first postoperative day pain on the visual analog scale, postoperative transfusion, and hemoglobin change). P < 0.05 was considered statistically significant. RESULTS: Thirty-five patients were treated in the inclusion period (2016-2017) and were matched to 35 cases in our database (2013-2016). Mean age was 43 years, and the most common fracture type was a both-column fracture (OTA/AO type C). Postoperative image analysis showed that reduction was achieved in 87.1% of the cases in the O-Arm group versus 64.7% in the control group (P < 0.05). Mean gap of the articular fragments was 3.6 mm in the O-Arm group compared with 5.6 mm (P = 0.01) in the control group. There was no significant difference between the 2 groups in regards to all other studied variables except a decrease in intraoperative blood loss and transfusions and an increase in surgical time with the O-Arm group. Finally, the total radiation dose was decreased using the intraoperative O-Arm compared with a routine postoperative computed tomography scan (dose length product in O-Arm: 498 mGy.cm; dose length product in historical group: 715 mGy.cm). CONCLUSIONS: Using intraoperative imaging and screw navigation for displaced acetabular fractures allow screw navigation with increasing articular surface reduction accuracy. Operative and anesthesia times were not increased, whereas radiation exposure to the patient was significantly decreased. We recommend the use of intraoperative imaging for the treatment of displaced acetabular fractures. LEVEL OF EVIDENCE: Therapeutic Level III.

PMID- 30299380 TI - Far Cortical Locking Fixation of Distal Femur Fractures is Dominated by Shear at Clinically Relevant Bridge Spans. AB - OBJECTIVES: Far cortical locking (FCL) constructs have been shown to increase axial interfragmentary displacement while limiting shear and have been specifically recommended in the treatment of distal femur fractures. However, there is no available data regarding their mechanical behavior within the range of bridge spans typically employed for comminuted distal femur fractures. This biomechanical study of distal femur locked plate fixation assessed four methods of diaphyseal fixation for associated axial and shear displacement at bridge spans typically employed in clinical practice. METHODS: Distal femur locking plates were used to bridge simulated fractures in femur surrogates with four different methods of diaphyseal fixation (bicortical locking, bicortical nonlocking, near cortical locking, and FCL). Axial and shear displacement were assessed at five different bridge spans for each fixation method. RESULTS: Diaphyseal fixation type was associated with the amount of shear (p = 0.04), but not the amount of axial displacement (p = 0.39). Specifically, FCL constructs demonstrated greater shear than bicortical locking (median 4.57 vs 2.94mm, p = 0.02) and bicortical nonlocking (median 4.57 vs 3.41mm, p = 0.02) constructs. CONCLUSIONS: Unexpectedly, FCL constructs demonstrated greater shear than bicortical locking and nonlocking constructs and similar axial displacement for all fixation methods. Bridge span had a dominant effect on displacement that interacted negatively with more flexible FCL diaphyseal fixation. Potentially interactive construct features are best studied in concert. Given the complexity of these relationships, computational modeling will likely play an integral role in future mechanotransduction research. PMID- 30299381 TI - Ease of use of electronic health records and relational coordination among primary care team members. AB - BACKGROUND: Electronic health records (EHRs) have potential to improve quality, health outcomes, and efficiency, but little is known about the mechanisms through which these improvements occur. PURPOSE: One potential mechanism could be that EHRs improve care team communication and coordination, leading to better outcomes. To test this hypothesis, we examine whether ease of EHR use is associated with better relational coordination (RC), a measure of team communication and coordination, among primary care team members. METHODOLOGY: Surveys of adult primary care team members (n = 304) of 16 practices of two accountable care organizations in Chicago and Los Angeles were analyzed. The survey included a validated measure of RC and a measure of ease of EHR use from a national survey. Linear regression models estimated the association of ease of EHR use and RC, controlling for care site and patient demographics and accounting for cluster-robust standard errors. An interaction term tested a differential association of ease of EHR use and RC for primary care providers (PCPs) versus non-PCPs. RESULTS: Ease of EHR use (mean = 3.5, SD = 0.6, range: 0-4) and RC were high (mean = 4.0, SD = 0.7, range: 0-5) but differed by occupation. In regression analyses, a 1-point increase in ease of EHR use was associated with a 0.36 point higher RC score (p = .001). The association of ease of EHR and RC use was stronger for non-PCPs than PCPs. CONCLUSION: Ease of EHR use is associated with better RC among primary care team members, and the benefits accrue more to non PCPs than to PCPs. PRACTICE IMPLICATIONS: Ensuring that clinicians and staff experience EHRs as easy to use for accessing and integrating data and for communication may produce gains in efficiency and outcomes through high RC. Future studies should examine whether interventions to improve EHR usability can lead to improved RC and patient outcomes. PMID- 30299382 TI - Integration of cardiologists with hospitals: Effects on physician compensation and productivity. AB - BACKGROUND: Hospital-physician vertical integration involving employment of physicians has increased considerably over the last decade. Cardiologists are one group of specialists being increasingly employed by hospitals. Although hospital physician integration has the potential to produce economic and societal benefits, there is concern that this consolidation may reduce competition and concentrate bargaining power among providers. In addition, hospitals may be motivated to offer cardiologists higher compensation and reduced workloads as an incentive to integrate. PURPOSE: The aim of the study was to determine if there are differences in compensation and clinical productivity, measured by work relative value units (RVUs), for cardiologists as they transition from being independent practitioners to being employed by hospitals. METHODOLOGY/APPROACH: This study was a quantitative, retrospective, longitudinal analysis, comparing the compensation and work RVUs of integrated cardiologists to their compensation and work RVUs as independent cardiologists. Data from the MedAxiom Annual Survey from 2010 to 2014 were used. Participants included 4,830 unique cardiologists that provided 13,642 pooled physician-year observations, with ownership status, compensation, work (RVUs), and other characteristics as variables for analysis. RESULTS: Results from the multivariate regressions indicate that average compensation for cardiologists increases by $129,263.1 (p < .001) when they move from independent to integrated practice. At the same time, physician work RVUs decline by 398.04 (p = .01). CONCLUSION: Our findings support the conjecture that hospitals may be offering higher pay and lower workloads to incentivize cardiologists to integrate. PRACTICE IMPLICATIONS: Although hospitals may have goals of quality improvement and lower costs, such goals may presently be secondary to service line growth and increased market power. There is reason to be cautious about some of the implications of hospital integration of cardiologists. PMID- 30299383 TI - Working around hierarchy: Resident and medical assistant teaming. AB - BACKGROUND: In health care, hierarchy can facilitate getting work done efficiently. It can also hinder performance by suppressing valuable contributions from lower-positioned individuals. Team-based care could mitigate negative effects by creating space for all team members to contribute their unique expertise. PURPOSE: This article sought to understand how resident-medical assistant (MA) dyads interacted before and after primary care clinics transitioned to team-based care. We also studied how they negotiated changes in interpersonal dynamics given the challenge these changes presented to hierarchical norms. METHODOLOGY: We conducted two qualitative interview studies, with 37 residents and 30 MAs at primary care clinics transitioning to team-based care. Interviews were transcribed, coded, and analyzed together using a thematic networks approach and focused coding. RESULTS: An intervention that promoted teamwork prompted resident-MA dyads to change their interactions to counter traditional hierarchy. Residents increasingly asked MAs questions about patient care, and MAs initiated interactions and volunteered ideas more frequently. We also found that MAs and residents expressed some discomfort with the hierarchical ambiguity that their new interactions produced and used alternate scripts to buffer this discomfort and to collaborate as teammates despite formal hierarchy. CONCLUSION: Among resident-MA dyads, a team-based care intervention changed interpersonal dynamics by blurring hierarchical lines and shifting traditional boundaries in ways that were uncomfortable for both groups. They were able to work around discomfort by using new scripts that downplayed the threat to hierarchy. PRACTICE IMPLICATIONS: Organizational structures that encourage greater interprofessional collaboration may neutralize barriers that formal hierarchy in medicine can pose for effective teamwork, but this process can also bring social discomfort. Our findings suggest that health care professionals may use microlevel strategies, such as alternative scripts, to overcome formal hierarchies without openly engaging them. Together, new organizational structures and interaction techniques can help professionals work around hierarchy and improve team performance. PMID- 30299384 TI - Stress, Workplace Violence, and Burnout in Nurses Working in King Abdullah Medical City During Al-Hajj Season. AB - BACKGROUND: The Hajj pilgrimage to Mecca, one of the largest mass gatherings in the world, is associated with various challenges for nurses. One of these challenges is increased levels of workplace violence. Therefore, handling and mitigating workplace violence against nurses during Hajj, when nurses face a higher risk of violence and most experience stress and burnout, is of particular importance. PURPOSE: The aims of this study were to identify the types and sources of workplace violence, examine the relationship between burnout in nurses and the variables of stress and workplace violence, and identify from the perspective of nurses measures to effectively handle and mitigate these issues during Hajj season. METHODS: This study used a descriptive correlational design. A convenience sample of 118 nurses completed the Perceived Stress Scale, the Maslach Burnout Inventory, and the modified version of the Joint Programme on Workplace Violence in the Health Sector published by the International Labour Office in Geneva. Data analysis was done using an independent samples t test and Pearson product-moment correlation. RESULTS: One hundred eighteen nurses completed the study. Over two thirds (65%) were female, and 56% reported experiencing at least one type of violence, of which bullying/mobbing, racial harassment, threats, and physical violence accounted for 61%, 15%, 12%, and 12%, respectively. Nurse managers displayed violent behaviors against 54% of the participants. Participants reported high levels of stress and burnout. A positive relationship was found between stress and emotional exhaustion (r = .387, p < .01). Providing effective security measures and staff training regarding how to deal with violence at the workplace were the main measures identified to help reduce workplace violence. CONCLUSIONS: Providing effective security measures and tailored intervention programs addressing how to deal with violence in the workplace may enable nurses to handle violent behaviors more effectively.

AB - Little is known about the infiltrative pattern of innate immune cells in primary melanoma compared with their paired metastases and in BRAF-mutated tumors. Therefore, our aim was to characterize the inflammatory microenvironment in primary ulcerated and nonulcerated melanomas and paired metastases, to investigate the relation between inflammation and BRAF mutation in primary melanoma and paired metastases, and to evaluate the effect of the analyzed biomarkers on melanoma-specific survival. A total of 385 primary tumors and 96 paired metastases were stained with immunohistochemistry for BRAF, CD163+ macrophages, CD123+ plasmacytoid dendritic cells, CD66b+ neutrophils, and E cadherin and estimated using objective computer-assisted image analysis. BRAF was semiquantitatively scored as either present or absent. In metastases of nonulcerated melanomas, we observed higher neutrophil (P=0.02) and macrophage (P=0.01) numbers. In the metastases of ulcerated melanomas, we found a higher number of macrophages (P<0.0001). Increase in the neutrophil numbers in the metastases was associated with poor patient survival after first relapse (hazard ratio=1.19, 95% confidence interval: 1.03-1.38, P=0.02). BRAF-positive primary tumors (P=0.02) and metastases (P=0.01) exhibited increased plasmacytoid dendritic cell numbers compared with BRAF-negative tumors. Lastly, primary melanomas in men had higher neutrophil numbers than women (P<=0.0001), and men had worse melanoma-specific survival (hazard ratio=1.52, 95% confidence interval: 1.04-2.21, P=0.03). Our data show that melanoma metastases are densely infiltrated with neutrophils, which affects survival. Our results also highlight the importance of recognizing the presence of inflammatory cells in the metastases as a prognostic marker, and that they may potentially be used to improve the precision of immunotherapy and BRAF targeted therapy. PMID- 30299388 TI - Optimal Emotional Profiles for Peak Performance in Strength and Conditioning. AB - Cooper, JJ, Johnson, M, Radcliffe, J, and Fisher, J. Optimal emotional profiles for peak performance in strength and conditioning. J Strength Cond Res XX(X): 000 000, 2018-This study investigated athletes' performance-related emotions and emotional profiles for optimal performance in strength and conditioning (S&C). It is suggested that the identification and control of emotions associated with successful and unsuccessful performances are essential for achieving peak psychological states and optimal performance in sports-related tasks. The individual zone of optimal functioning (IZOF) model outlines an idiographic and comprehensive conceptual framework of interrelated dimensions that describe the structure and dynamics of subjective emotional experiences and performance related psychobiological states. With institutional ethics approval, 13 competitive elite athletes (male, n = 7; female, n = 6: mean age = 21.7 +/- 4.0 years) completed IZOF-based emotion profiling, in which participants were asked to recall their perceived best and worst S&C session, outlining emotions and intensity within 4 global emotional categories. A significant difference was evidenced between best ever and worst ever performance within positive functional emotions (p < 0.001, d = 3.63) and negative dysfunctional emotions (p < 0.001, d = 4.92). Initial findings suggest that perceived peak performance states within S&C are associated with a high intensity of positive functional emotions (confident, motivated, and energetic) and a low intensity of negative dysfunctional emotions (worn out, sluggish, annoyed, and discouraged). Although future research is necessary to fully understand this area, the present data suggest that to assist athletes in achieving perceived peak performance states within S&C, psychological skills and strategies should be informed and developed in collaboration with sport psychologists, with the aim of achieving an optimal emotional profile.

Effect of velocity-based loading on acceleration kinetics and kinematics during sled towing. J Strength Cond Res XX(X): 000-000, 2018-Sled towing (ST) provides an external load in the form of a sled towed using a shoulder or waist harness and cord behind the athlete. Loading strategies have varied greatly between studies, and despite many investigations, there is little agreement on the optimum sled loading to develop the acceleration phase. The aim of this study was to investigate the kinetics and kinematics of velocity-based ST during the acceleration phase of sprinting. Twelve academy rugby league players performed a series of 6-m sprints in different conditions; uninhibited, 10, 15, and 20% velocity decrement (VDec). Sagittal plane kinematics and kinetic measures were examined using 1-way repeated-measures analysis of variance. Results indicated that ST affected trunk, knee, and ankle joint kinematics (p < 0.05). Peak knee flexion increased as sled loads increased (p < 0.05), which may enable athletes to lower their center of mass and increase their horizontal force application. Net horizontal and propulsive impulse measures were greater in all sled conditions (p < 0.05), which increased significantly because sled loadings were heavier. In conclusion, this study highlights the effects of differential loads to help coaches understand acute kinetics and kinematic changes to improve the planning of sprint training. PMID- 30299390 TI - A Novel Approach for Athlete Profiling: The Unilateral Dynamic Strength Index. AB - Bishop, C, Read, P, Lake, J, Loturco, I, and Turner, A. A novel approach for athlete profiling: The unilateral dynamic strength index. J Strength Cond Res XX(X): 000-000, 2018-The Dynamic Strength Index (DSI) provides a ratio of the peak force an athlete can produce in both isometric and ballistic tasks. Although the DSI measured during bilateral tests has been examined, unilateral DSI scores have not been reported to date and thus was the aim of the present study. Twenty eight recreational sport athletes performed 3 trials of a unilateral isometric squat and countermovement jump (CMJ) to measure peak force in each task across 2 separate test sessions. The unilateral DSI was calculated using both left vs. right and dominant vs. nondominant limbs. Good to excellent reliability was shown in the isometric squat (intraclass correlation coefficient [ICC] = 0.86-0.96; coefficient of variation [CV] <= 5.7%) and the CMJ (ICC = 0.83-0.93; CV <= 5.8%) on both limbs. The DSI showed moderate to good reliability (ICC = 0.71-0.79; CV = 7.54-11.9%). Dynamic Strength Index scores of 0.52-0.55 and 0.55-0.59 were reported on the left and right limbs, respectively, with no significant differences reported between limbs. A significant difference (p = 0.04) was seen for the CMJ between left and right during the second test session only. The dominant and nondominant limbs reported mean DSI scores of 0.53-0.57, and significant differences were evident between limbs in both the isometric squat and CMJ (p < 0.01). This study provides normative data for the unilateral DSI and indicates acceptable levels of reliability, whereas the consistency of individual measures of peak force can be considered good when quantified unilaterally.

Comparison of step-by-step kinematics of elite sprinters' unresisted and resisted 10-m sprints measured with Optojump or Musclelab. J Strength Cond Res XX(X): 000-000, 2018-The purpose of this study was to compare step-by-step kinematics of unresisted and resisted 10-m sprints measured with the Optojump or Musclelab on elite sprinters. Six subjects (age 30.0 +/- 5.1 years, body mass 76.3 +/- 5.3 kg, body height 1.79 +/- 0.09 m, and 100-m personal best 10.51 +/- 0.3 s) performed 2 unresisted and 2 sets of 2 resisted (10 and 20% of body mass) 30-m sprints in random order (6 sprints in total) in 1 session in which kinematics of the first 10 m were measured with the Optojump and Musclelab. The main finding was that there were no significant differences between the measurements made with the Optojump and Musclelab systems. In addition, it was possible to discriminate most kinematic variables per step of the first 10 m when different loads (10 and 20% of body mass) had to be pulled during the 30-m sprints. The variations in sprint times associated with changes in the resistance provided by the dynaSpeed were mainly caused by a decrease in step length as the resistance increased. It was concluded that the 2 systems are valid and could help coaches, researchers, and athletes by providing more detailed information about possible changes to kinematics during training and sprinting with different resistances.

AB - Sanders, GJ, Boos, B, Rhodes, J, Kollock, RO, and Peacock, CA. Competition-based heart rate, training load, and time played above 85% peak heart rate in NCAA division I women's basketball. J Strength Cond Res XX(X): 000-000, 2018 Basketball athletes frequently engage in intensities >=85% HRpeak throughout competition. Knowing the time spent competing at intensities >=85% HRpeak can improve training protocols. The purpose of the study was to assess heart rate responses across 4-quarter games (N = 31) in an NCAA division I women's basketball season. Ten female athletes were tested and monitored with heart rate based wearable microsensor devices. Before the season, HRpeak was recorded through a peak metabolic test (V[Combining Dot Above]O2peak). Average (HRavg) and HRpeak were recorded for each game, and time spent in 5 heart rate zones (HRZones) were recorded: HRZone1 = 50-60% HRpeak, HRZone2 = 60-70% HRpeak, HRZone3 = 70-76% HRpeak, HRZone4 = 77-84% HRpeak, and HRZone5 = 85-100% HRpeak. Training load was calculated with the summated-heart-rate-zone model (SHRZmod). There was a main effect of position (p <= 0.019) and quarter (p <= 0.005) on SHRZmod and on time spent in HRZone1-5. Athletes accumulated the most time in HRZone4 and HRZone5 and in the fourth quarter, and SHRZmod was the greatest in the fourth quarter. There was no main effect for HRavg and HRpeak (p >= 0.110). Athletes averaged 34.5 minutes per game competing in HRZone5 or >=85% HRpeak with nearly one-third of those minutes accumulated in the fourth quarter. Although there were no differences in HRavg and HRpeak from quarter to quarter, SHRZmod increased from the first to fourth quarter. Utilizing time spent in heart rate zones and training load with SHRZmod can provide valuable information to practitioners regarding the intensity and physiological demands of competitive basketball games.

AB - Lysenko, EA, Popov, DV, Vepkhvadze, TF, Sharova, AP, and Vinogradova, OL. Moderate-intensity strength exercise to exhaustion results in more pronounced signaling changes in skeletal muscles of strength-trained compared with untrained individuals. J Strength Cond Res XX(X): 000-000, 2018-The aim of our investigation was to compare the response pattern of signaling proteins and genes regulating protein synthesis and degradation in skeletal muscle after strength exercise sessions performed to volitional fatigue in strength-trained and untrained males. Eight healthy recreationally active males and 8 power-lifting athletes performed 4 sets of unilateral leg presses to exhaustion (65% 1 repetition maximum). Biopsy samples of m. vastus lateralis were obtained before, 1 and 5 hours after cessation of exercise. Phosphorylation of p70S6k, 4EBP1, and ACC increased, whereas phosphorylation of eEF2 and FOXO1 decreased only in the trained group after exercise. Expression of DDIT4, MURF1, and FOXO1 mRNAs increased and expression of MSTN mRNA decreased also only in the trained group after exercise. In conclusion, moderate-intensity strength exercise performed to volitional fatigue changed the phosphorylation status of mTORC1 downstream signaling molecules and markers of ubiquitin-proteasome system activation in trained individuals, suggesting activation of protein synthesis and degradation. In contrast to the trained group, signaling responses in the untrained group were considerably less pronounced. It can be assumed that the slowdown in muscle mass gain as the athletes increase in qualification cannot be associated with a decrease in the sensitivity of systems regulating protein metabolism, but possibly with inadequate intake or assimilation of nutrients necessary for anabolism. Perhaps, the intake of highly digestible protein or protein carbohydrate dietary supplements could contribute to the increase in muscle mass in strength athletes. PMID- 30299393 TI - Effect of the Fatigue on the Physical Performance in Different Small-Sided Games in Elite Football Players. AB - Calderon Pellegrino, G, Paredes-Hernandez, V, Sanchez-Sanchez, J, Garcia-Unanue, J, and Gallardo, L. Effect of the fatigue on the physical performance in different small-sided games in elite football players. J Strength Cond Res XX(X): 000-000, 2018-Football players need to be able to perform high-intensity efforts of short duration with brief recovery periods. The aim of this study was to analyze the influence of the pitch dimension on high-intensity actions and the effect of a repeated sprint ability (RSA) test on the physical performance in different 4-against-4 (4v4) small-sided games (SSG) dimensions. Sixteen U-18 elite football players performed an RSA test between two 4v4 SSGs (pre and post) to induce fatigue and compare physical data. Speed, sprint number, accelerations, sprint distance, total distance covered, and total distance covered of the players at different intensities were evaluated in 3 different SSGs (125, 150, 250, and 300 m). Results revealed a significant detriment of physical performance in the 125-m SSG after RSA, mostly in number of sprints (-6.56; confidence interval [CI] 95%: -10.13 to -3.00; effect size [ES]: 1.13 p < 0.001), accelerations (-2.69; CI 95%: -5.13 to -0.24; ES: 0.68; p = 0.032), and sprint distance (-65.44 m; CI 95%: -103.73 to -27.16; ES: 1.20; p = 0.001). In bigger SSGs (250 and 300 m), higher distance at high intensity was covered and Vmax, Vmean, and sprint distance were greater. In summary, accelerations, sprint number, and fatigue were higher in smaller pitches, and higher velocities were reached in bigger SSGs. Football players should be aware that changes in pitch size can modify the physical performance on high-intensity actions in SSGs. PMID- 30299395 TI - Very early-onset inflammatory bowel disease: an integrated approach. AB - PURPOSE OF REVIEW: Immune dysregulation disorders are among the most rapidly growing set of inborn errors of immunity. One particular subset is the category where early-onset inflammatory bowel disease (IBD) is the most common manifestation. These disorders are being increasingly appreciated although there has been minimal effort to articulate a unified approach to their diagnosis and management. This review will cover current thinking and strategies related to diagnosis and management of very early-onset IBD. RECENT FINDINGS: There is an expanding set of monogenic causes of early-onset IBD. In many cases, the precise genetic cause dictates management. Lessons learned from the management of these monogenic conditions can sometimes be extrapolated to other refractory cases of IBD. SUMMARY: An integrated approach to diagnosis, risk analysis, and management can include diagnostic approaches not often utilized for traditional IBD such as whole exome sequencing. Management can also include nontraditional approaches such as targeted biologics or hematopoietic cell transplantation. PMID- 30299396 TI - Very early onset IBD: novel genetic aetiologies. AB - PURPOSE OF REVIEW: To summarize the current understanding and recent advances on the genetic aetiology in the pathogenesis of very early onset inflammatory bowel disease (VEO-IBD). RECENT FINDINGS: IBD is a chronic disorder of the gastrointestinal tract whose manifestation is a result of complex interactions between genetics, environment, immune system and microbial flora. Over 230 IBD risk loci have been reported in genome wide association studies but the genetic contribution of the majority of these loci in the manifestation of IBD is very low. Patients with VEO-IBD present with a more severe disease than older patients, characterized by poor prognosis and failure of conventional therapy. Recent studies have reported several monogenic diseases with high penetrance that present with IBD and IBD-like intestinal manifestations and overlap with primary immunodeficiencies. Increasing body of evidence supports a prominent role of genetics in the onset of VEO-IBD. New genetic variants and diagnoses in VEO-IBD are reviewed and current challenges in therapy with potential strategy to manage the disease are discussed. SUMMARY: Functional analysis of the genes implicated in monogenic IBD has increased the understanding of the underlying pathobiological mechanism of the disease. This knowledge can be used to personalize medicine for specific patients, improving the standard of care and quality of life. PMID- 30299397 TI - Biological treatments for severe asthma: where do we stand? AB - PURPOSE OF REVIEW: For patients with severe asthma, disease control is not achieved resulting in persistent morbidity and risks for exacerbations. The advent of biologics is providing a new form of treatment for many with severe asthma. RECENT FINDINGS: Four mAb biologics are approved for clinical use: omalizumab (anti-IgE) and three antieosinophilic interventions (mepolizumab, reslizumab, and benralizumab). These four biologics target components of the type 2-inflammatory pathway which is reflected by biomarkers: peripheral blood eosinophils and exhaled nitric oxide. In severe asthma, biologics have reduced asthma exacerbations. The antieosinophilic biologics have also improved lung function. The safety profile of these biologics has been good. SUMMARY: For patients with severe asthma and biomarkers indicating a type 2 inflammatory pathway, the addition of biologics has proven to be an effective approach to achieve disease control and is an appropriate next step treatment. PMID- 30299398 TI - Secondary antibody deficiency in neurology. AB - PURPOSE OF REVIEW: Induction of lymphocyte depletion is increasingly used as a therapeutic strategy for central and peripheral neuroinflammatory disease. However, there is also a growing recognition of the treatment-related complication of secondary antibody deficiency (SAD). Although the occurrence of hypogammaglobulinaemia is a recognized phenomenon during immunomodulation, robust data on the coexistence of impaired responses to immunization, and significant and/or atypical infections is scarce. Here we review the literature on SAD in anti-CD20 therapy. RECENT FINDINGS: Several factors that may increase the incidence of SAD have now been identified, including low levels of immunoglobulins prior to the commencement of B-cell ablation therapy, duration of maintenance therapy, and concurrent or prior use of other immunosuppressing agents such as cyclophosphamide and steroids. Measurement of disease-specific antibodies and vaccine response are likely to be helpful adjuncts to measurement of serum immunoglobulin levels during B-cell depleting therapy. Supportive treatment may include amending the treatment schedule to limit cumulative dose. SUMMARY: B-cell depleting agents offer considerable therapeutic benefit in neurology. We propose modifications in current practice that include risk stratification and early identification of SAD, with the aim of minimising morbidity and mortality related to this underappreciated condition. PMID- 30299399 TI - Advances in site-specific gene editing for primary immune deficiencies. AB - PURPOSE OF REVIEW: Conventional gene therapy has been a successful, curative treatment modality for many primary immune deficiencies with significant improvements in the last decade. However, the risk of leukemic transformation with viral-mediated gene addition still remains, and unregulated gene addition is not an option for certain diseases in which the target gene is closely controlled. The recent bloom in genome modification platforms has created the opportunity to site-specifically correct mutated DNA base pairs or insert a corrective cDNA minigene while maintaining gene expression under control of endogenous regulatory elements. RECENT FINDINGS: There is an abundance of ongoing research utilizing programmable nucleases to facilitate site-specific gene correction of many primary immune deficiencies including X-linked severe combined immune deficiency, X-linked chronic granulomatous disease, Wiskott-Aldrich syndrome, X-linked hyper-IgM syndrome, X-linked agammaglobulinemia, and immune dysregulation, polyendocrinopathy, enteropathy, X-linked. In all, these studies have demonstrated the ability to integrate corrective DNA sequences at a precise location in the genome at rates likely to either cure or ameliorate disease. SUMMARY: Gene editing for primary immune deficiency (PID) has advanced to the point to that translation to clinical trials is likely to occur in the next several years. At the current pace of research in DNA repair mechanisms, stem cell biology, and genome-editing technology, targeted genome modification represents the next chapter of gene therapy for PID. PMID- 30299400 TI - Daily Stress Processes as Contributors to and Targets for Promoting Cognitive Health in Later Life. AB - OBJECTIVE: The aim of this study was to test the hypothesis that daily stress processes, including exposure and emotional reactivity to daily stressors, are associated with response time inconsistency (RTI), an indicator of processing efficiency and cognitive health. Furthermore, we considered daily stress cognitive health associations at the level of individual differences and within persons over time. METHODS: Participants were 111 older adults (Mean=80 years, Range=66-95) enrolled in a measurement burst study where assessments of response time based cognitive performance, stressful experiences, and affect were administered on each of 6 days over a two-week period. This protocol was repeated every six months for 2.5 years. Multilevel modeling was used to examine frequency of stressor exposure, non-stressor affect, and affect reactivity to daily stressors as individual difference and time-varying predictors of RTI. RESULTS: Between-persons, higher levels of non-stressor negative affect (b=0.41, 95%CI: 0.01, 0.83, p=.055) and negative affect reactivity (b=0.80, 95%CI: 0.18, 1.42, p=.012) were associated with greater RTI. Within-persons over time, higher levels of negative affect (b=0.20, 95%CI: 0.06, 0.34, p=.006) and negative affect reactivity (b=0.13, 95%CI: 0.02, 0.24, p=.018) were associated with increased RTI among the oldest portion of the sample, while higher levels of positive affect (b=-0.11, 95% CI: -0.21, -0.02, p=.019) were associated with reduced RTI. CONCLUSIONS: Negative affect reactions to daily stressors are associated with compromised RTI both between- and within-persons. Findings suggest that emotional reactions to daily stressors contribute to compromise older adults' cognitive health, while increased positive affect may be beneficial. PMID- 30299401 TI - The Relationship Between Daytime Salivary Melatonin and Gastrointestinal Symptoms in Young Adults Seeking Psychiatric Care. AB - OBJECTIVE: The pathophysiology of irritable bowel syndrome (IBS) is not completely understood, although we do know that patients with IBS have a high prevalence of psychiatric comorbidity (mainly depression and anxiety disorders). Melatonin, produced in the gastrointestinal tract, influences gut motility. Psychiatric conditions are associated with circadian disturbances in peripheral melatonin levels. This study aimed to investigate associations between daytime salivary melatonin and gastrointestinal symptoms in young adult psychiatric patients. METHODS: Ninety-six patients (86% women), age 18-25 years (mean 21, SD=2), seeking psychiatric care with primarily anxiety disorders, affective disorders, or both were included in the study. Total scores from The Gastrointestinal Symptoms Rating Scale - IBS (GSRS-IBS) were compared with salivary melatonin measured at three time points (30 minutes after waking up, at 11:00 hours and 30 minutes after lunch) during the waking hours of one day. RESULTS: When controlling for potential confounders, melatonin levels in saliva 30 minutes after lunch remained significantly correlated to the total GSRS-IBS score after correction for multiple testing (B=0.016, SE=0.006, p=0.015, q=0.045). In a post hoc analysis, symptoms of gastrointestinal pain and bloating contributed most to this association. CONCLUSIONS: In young adult psychiatric patients salivary melatonin levels after lunch are associated with gastrointestinal symptoms, which is consistent with the proposed effect of elevated levels of gastrointestinal melatonin on gut motility. This result suggests a link between IBS symptoms and regulation of melatonin in patients with psychiatric disorders.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30299402 TI - Maternal Thyroid Function During Pregnancy or Neonatal Thyroid Function and Attention Deficit Hyperactivity Disorder: A Systematic Review. AB - BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is the most common neurobehavioral disorder in children, yet its etiology is poorly understood. Early thyroid hormone disruption may contribute to the development of ADHD. Disrupted maternal thyroid hormone function has been associated with adverse neurodevelopmental outcomes in children. Among newborns, early-treated congenital hypothyroidism has been consistently associated with later cognitive deficits. METHODS: We systematically reviewed literature on the association between maternal or neonatal thyroid hormones and ADHD diagnosis or symptoms. We searched Embase, Pubmed, Cinahl, PsycInfo, ERIC, Medline, Scopus, and Web of Science for articles published or available ahead of print as of April 2018. RESULTS: We identified 28 eligible articles: 16 studies of maternal thyroid hormones, seven studies of early-treated congenital hypothyroidism, and five studies of neonatal thyroid hormones. The studies provide moderate evidence for an association between maternal thyroid hormone levels and offspring ADHD, some evidence for an association between early-treated congenital hypothyroidism and ADHD, and little evidence for an association between neonatal thyroid hormone levels and later ADHD. CONCLUSIONS: The reviewed articles suggest an association between maternal thyroid function and ADHD, and possibly between early-treated congenital hypothyroidism and ADHD. Study limitations, however, weaken the conclusions in our systematic review, underlining the need for more research. Importantly, there was much variation in the measurement of thyroid hormone function and of ADHD symptoms. Recommendations for future research include using population-based designs, attending to measurement issues for thyroid hormones and ADHD, considering biologically relevant covariates (e.g., iodine intake), and assessing nonlinear dose-responses. PMID- 30299403 TI - The Authors Respond. PMID- 30299404 TI - Lifestyle Patterns and Survival Following Breast Cancer in the Carolina Breast Cancer Study. AB - BACKGROUND: Few studies have examined the impact of lifestyle patterns on survival following breast cancer. We aimed to identify distinct lifestyle patterns based on five behavior/dietary exposures among a population-based sample of women diagnosed with breast cancer and to examine their association with subsequent survival. METHODS: In the Carolina Breast Cancer Study Phases I/II, we interviewed 1,808 women 20-74 years of age following diagnosis of invasive breast cancer. We determined vital status using the National Death Index (717 deaths, 427 from breast cancer; median follow-up 13.56 years). We assessed lifestyle patterns using a latent class analysis based on five behavioral and dietary exposures: current versus never/former smokers; low versus high vegetable and fruit intake; high and low/moderate, versus no alcohol consumption; and no and low/moderate, versus high regular physical activity. We used Cox regression to estimate covariate-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause mortality, and cause-specific and subdistribution HRs for breast cancer-specific mortality within 5 years and 13 years postdiagnosis conditional on 5-year survival. RESULTS: We identified three distinct lifestyle patterns: healthy behavior and diet (n = 916); healthy behavior and unhealthy diet (n = 624); and unhealthy behavior and diet (n = 268). The unhealthy (vs. healthy) behavior and diet pattern was associated with a 13-year conditional all cause mortality HR of 1.4 (95% CI = 1.1, 1.9) and with 13-year conditional breast cancer-specific and subdistribution HRs of 1.2 (95% CI = 0.79, 1.9) and 1.2 (95% CI = 0.77, 1.8), respectively. CONCLUSIONS: Behavioral and dietary patterns can be used to identify lifestyle patterns that influence survival patterns following breast cancer diagnosis. PMID- 30299405 TI - Quality of Maternal Height and Weight Data from the Revised Birth Certificate and Pregnancy Risk Assessment Monitoring System. AB - BACKGROUND: The 2003 revision of the US Standard Certificate of Live Birth (birth certificate) and Pregnancy Risk Assessment Monitoring System (PRAMS) are important for maternal weight research and surveillance. We examined quality of prepregnancy body mass index (BMI), gestational weight gain, and component variables from these sources. METHODS: Data are from a PRAMS data quality improvement study among a subset of New York City and Vermont respondents in 2009. We calculated mean differences comparing prepregnancy BMI data from the birth certificate and PRAMS (n = 734), and gestational weight gain data from the birth certificate (n = 678) to the medical record, considered the gold standard. We compared BMI categories (underweight, normal weight, overweight, obese) and gestational weight gain categories (below, within, above recommendations), classified by different sources, using percent agreement and the simple kappa statistic. RESULTS: For most maternal weight variables, mean differences between the birth certificate and PRAMS compared with the medical record were less than 1 kg. Compared with the medical record, the birth certificate classified similar proportions into prepregnancy BMI categories (agreement = 89%, kappa = 0.83); PRAMS slightly underestimated overweight and obesity (agreement = 84%, kappa = 0.73). Compared with the medical record, the birth certificate overestimated gestational weight gain below recommendations and underestimated weight gain within recommendations (agreement = 81%, kappa = 0.69). Agreement varied by maternal and pregnancy-related characteristics. CONCLUSIONS: Classification of prepregnancy BMI and gestational weight gain from the birth certificate or PRAMS was mostly similar to the medical record but varied by maternal and pregnancy related characteristics. Efforts to understand how misclassification influences epidemiologic associations are needed. PMID- 30299407 TI - Re: Herpesvirus Infection in Infants with Gastroschisis. PMID- 30299406 TI - Nonparticipation Selection Bias in the MOBI-Kids Study. AB - BACKGROUND: MOBI-Kids is a 14-country case-control study designed to investigate the potential effects of electromagnetic field exposure from mobile telecommunications devices on brain tumor risk in children and young adults conducted from 2010 to 2016. This work describes differences in cellular telephone use and personal characteristics among interviewed participants and refusers responding to a brief nonrespondent questionnaire. It also assesses the potential impact of nonparticipation selection bias on study findings. METHODS: We compared nonrespondent questionnaires completed by 77 cases and 498 control refusers with responses from 683 interviewed cases and 1501 controls (suspected appendicitis patients) in six countries (France, Germany, Israel, Italy, Japan, and Spain). We derived selection bias factors and estimated inverse probability of selection weights for use in analysis of MOBI-Kids data. RESULTS: The prevalence of ever-regular use was somewhat higher among interviewed participants than nonrespondent questionnaire respondents 10-14 years of age (68% vs. 62% controls, 63% vs. 48% cases); in those 20-24 years, the prevalence was >=97%. Interviewed controls and cases in the 15- to 19- and 20- to 24-year-old age groups were more likely to have a time since start of use of 5+ years. Selection bias factors generally indicated a small underestimation in cellular telephone odds ratios (ORs) ranging from 0.96 to 0.97 for ever-regular use and 0.92 to 0.94 for time since start of use (5+ years), but varied in alternative hypothetical scenarios considered. CONCLUSIONS: Although limited by small numbers of nonrespondent questionnaire respondents, findings generally indicated a small underestimation in cellular telephone ORs due to selective nonparticipation. PMID- 30299408 TI - Transfemoral aortic valve implantation with new-generation devices: the repositionable Lotus vs. the balloon-expandable Edwards Sapien 3 valve. AB - BACKGROUND: New-generation transcatheter heart valves have been developed to reduce complications of transcatheter aortic valve implantation (TAVI). With this study we sought to compare procedural and 30-day outcomes of the new-generation repositionable Boston Scientific Lotus (Lotus) and the balloon-expandable Edwards Sapien 3 (ES3) transcatheter heart valves. METHODS: A total of 315 patients with severe symptomatic aortic stenosis undergoing transfemoral TAVI with Lotus or ES3 included in two large Italian registries were considered for this analysis. After propensity matching, 93 matched pairs of patients were included. Outcomes were evaluated according to Valve Academic Research Consortium-2 definition at discharge and 30 days. RESULTS: There were no differences in baseline characteristics, except for lower mean aortic gradient and larger mean aortic annulus in the ES3-treated patients. Valve Academic Research Consortium-2 defined device success was high and comparable between groups (97.8 for Lotus vs. 98.9% for ES3, P = 0.09). The frequency of moderate/severe paravalvular leak was low and similar for both devices (2.2 vs. 1.1%, P = 0.10). At 30 days, both groups showed low all-cause mortality (5.4 vs. 1.1%, P = 0.10) and rates of disabling stroke (3.2 vs. 1.1%, P = 0.31). New pacemaker implantation was more common after Lotus deployment (31.7 vs. 10.5%, P < 0.001). CONCLUSION: Transfemoral TAVI with both Lotus and ES3 resulted in favorable clinical and hemodynamic procedural and 30-day outcomes. Rates of significant paravalvular leak were low with both devices. The Lotus valve was associated with higher risk of pacemaker implantation. PMID- 30299410 TI - Carotid Doppler assessment in patients undergoing transcatheter aortic valve implantation. PMID- 30299409 TI - Safety and effectiveness of the transsubclavian approach for transcatheter aortic valve implantation with the 14-F CoreValve Evolut R device. AB - AIMS: In addition to the transfemoral route, common approaches for transcatheter aortic valve implantation (TAVI) are the transapical and transaortic ones. Yet, these are associated with morbidity. The transsubclavian approach (TSA) is an alternative to minimize invasiveness. METHODS: Fifteen consecutive patients underwent TAVI via TSA using the CoreValve Evolut R. The 14F delivery system without sheath was directly introduced into the artery. RESULTS: Success was 100%; contrast volume was 99.4 +/- 29.58 ml. Patients were extubated after 1.66 +/- 0.89 h. Hemoglobin drop was 0.64 +/- 0.28 g/dl. There were no complications. Hospital stay was 4.53 +/- 1.24 days: 11 patients were discharged home, the remainder to rehabilitation. CONCLUSION: TSA is associated with limited morbidity, early patient mobilization, short hospitalization.

PMID- 30299412 TI - Sucrose but Not Nitrate Ingestion Reduces Strenuous Cycling-induced Intestinal Injury. AB - PURPOSE: Strenuous exercise induces intestinal injury, which is likely related to splanchnic hypoperfusion and may be associated with gastrointestinal complaints commonly reported during certain exercise modalities. Increasing circulating nitric oxide (NO) levels or inducing postprandial hyperemia may improve splanchnic perfusion, thereby attenuating intestinal injury during exercise. Therefore, we investigated the effects of both dietary nitrate ingestion and sucrose ingestion on splanchnic perfusion and intestinal injury induced by prolonged strenuous cycling. METHODS: In a randomized cross-over manner, 16 well trained male athletes (age: 28+/-7 y; Wmax: 5.0+/-0.3 W.kg) cycled 60 min at 70% Wmax following acute ingestion of: sodium nitrate (NIT; 800 mg NO3), sucrose (SUC; 40 g) or a water placebo (PLA). Splanchnic perfusion was assessed by determining the gap between gastric and arterial pCO2 (gapg-apCO2) using gastric air tonometry. Plasma intestinal fatty-acid binding protein (I-FABP) concentrations, reflecting enterocyte damage, were assessed every 20 min during and up to 60 min of post-exercise recovery. RESULTS: The exercise protocol resulted in splanchnic hypoperfusion, as gapg-apCO2 levels increased during exercise (P<0.001), with no differences between treatments (P=0.47). Although plasma I-FABP concentrations increased during exercise and post-exercise recovery for all treatments (P<0.0001), the increase was different between treatments (P<0.0001). Post-hoc comparisons showed an attenuated increase in I-FABP in SUC vs PLA (P=0.020). In accordance, I-FABP area under the curve (AUC0-120) was significantly lower in SUC vs PLA (57,270+/-77,425 vs 114,907+/-91,527 pg.mL.120 min, P=0.002). No differences were observed between NIT and PLA (P=0.99). CONCLUSION: Sucrose but not nitrate ingestion lowers intestinal injury evoked during prolonged strenuous cycling. These results suggest that sucrose ingestion, but not nitrate, prevents hypoperfusion-induced gastrointestinal damage during exercise and, as such, may help to lower exercise-related gastrointestinal complaints.

AB - INTRODUCTION: It is well known that supplemental oxygen can increase aerobic power output during high-intensity and/or maximal efforts at moderate altitude, yet the effects on self-selected work rate during lower-intensity, submaximal exercise are unknown. We reasoned that if the degree of arterial oxygen saturation (SaO2) influences teleoanticipatory regulation of power output, supplemental oxygen given at moderate altitude would increase average power output during exercise performed at self-selected work rates corresponding to RPE 9 (very light) and 13 (somewhat hard). METHODS: Twenty-three subjects (17 males, 6 females) completed one familiarization [fraction of inspired O2 (FIO2)=0.209] and two blinded, experimental trials (FIO2=0.209 and FIO2=0.267). In each trial, subjects self-regulated their work rate on a cycle ergometer to maintain RPE 9 for 5 min and RPE 13 for 10 min, before performing an incremental step test to exhaustion (25 W/min). Oxygen consumption (VO2) and SaO2 via pulse oximetry (SpO2) were continuously monitored. Subjects were asked to guess the experimental condition after each stage of the protocol. RESULTS: Supplemental oxygen increased SpO2 throughout exercise (~4%; P<0.001) and was associated with greater peak power output (4+/-4%; P<0.001) and VO2 (5+/-10%; P=0.010) during the incremental test, but did not increase average power output selected during exercise at RPE 9 (P=0.235) or 13 (P=0.992). Subjects were unable to perceive the difference in FIO2 at any stage (P>0.14). CONCLUSIONS: Small increases in inspired oxygen concentration at moderate altitude are imperceptible and do not appear to influence selection of submaximal work rates at RPE <= 13. PMID- 30299415 TI - Closed Wound Sub-Fascial Suction Drainage in Posterior Fusion Surgery for Adolescent Idiopathic Scoliosis: A Prospective Randomize Control study. AB - STUDY DESIGN: Prospective randomized control study. OBJECTIVE: To compare the complication rate in adolescent idiopathic scoliosis (AIS) posterior spinal fusion (PSF) surgery with and without drainage. SUMMARY OF BACKGROUND DATA: PSF is the mainstay of surgical treatment for AIS. Drains are commonly used despite contradictory findings in the literature for their having any clear advantage. METHODS: A total of 100 AIS patients undergoing instrumented PSF were blindly randomized into 2 groups of either a deep drain or no drain. The collected data included wound follow-up findings, hemoglobin, hematocrit, vital signs and fever levels, and mean 20 months follow-up. RESULTS: Fifty-two patients were randomly allocated to the "no drain" group and 48 to the "drain" group. There were no differences in patient characteristics, surgical data and hemoglobin and hematocrit levels between the 2 groups. Only 4 units of packed cells were given in total. Fever during the first postoperative 1-3 days was equal, but increased in the no drain group on day 6 (P = 0.017). Length of hospitalization was equal (6 days) for all the patients. The mean follow-up period was 20 months [8.5-30.7 (SD 6.4)]. Complications included one case (1.9%) of pneumonia in the "no-drain" group, wound dehiscence in 2 cases (3.8%) in the "no-drain" group and in one case (2.1%) in the "drain" group, and 2 cases (3.8%) of superficial wound infection in the "no-drain" group. There was no case of deep infection in either group. CONCLUSION: The current results indicate that there is no advantage to deep drainage in AIS patients undergoing PSF. The number of wound healing complications was low and identical for both the drain and no-drain groups. LEVEL OF EVIDENCE: 2. PMID- 30299416 TI - Don't you wish you had fused to the pelvis the first time: a comparison of reoperation rate and correction of pelvic obliquity. AB - STUDY DESIGN: Multicenter retrospective OBJECTIVE.: To compare pelvic obliquity correction and reoperation rate in neuromuscular scoliosis patients who had their pelvis included in a posterior spinal fusion (pelvic fusion, PF) at their index procedure vs revision procedures. SUMMARY OF BACKGROUND DATA: There is limited information on outcomes specific to fusing to the pelvis for neuromuscular scoliosis in a revision operation versus index surgery. METHODS: Charts and radiographs were reviewed of patients with PF for neuromuscular scoliosis from 01/2003 to 08/2015 at 4 high volume pediatric spine centers with > 2 year follow up. RESULTS: 285 patients met inclusion criteria; 271 had PF done at index surgery and 14 had PF done during revision surgery. Prior to index procedure, there were no significant differences in Cobb angle (p = 0.13). Prior to pelvic fusion there was no difference in pelvic obliquity (p = 0.26). At the time of fusion to the pelvis, estimated blood loss (p = 0.23) and operative time (p = 0.43) did not differ between index and revision groups. Percent correction in pelvic obliquity was similar for both groups (p = 0.72). Overall, 69 patients had complications requiring return to the OR. Excluding the revision surgery for inclusion of the pelvis for the revision group, there was still a lower reoperation rate with index PF (22.9%, n = 62/271) than revision PF (50.0%, n = 7/14) (p = 0.02). Implant failures were significantly higher in the revision group (index = 7.4%, 20/271; revision = 42.9%, 6/14; p < 0.001). CONCLUSION: PF at the index spinal fusion led to similar correction of pelvic obliquity with approximately half the reoperation rate compared to PF at a revision surgery. Operative time and blood loss were similar between index and revision spinal fusion. LEVEL OF EVIDENCE: 4. PMID- 30299417 TI - How common is medial and lateral shoulder discordance in lenke 1 and 2 curves? a preoperative analysis of medial and lateral shoulder balance among 151 lenke 1 and 2 adolescent idiopathic scoliosis (AIS) patients. AB - STUDY DESIGN: .: Retrospective study of prospectively collected data. OBJECTIVE: .: To analyze the incidence and the patterns of medial and lateral shoulder discordance among Lenke 1 and 2 patients. SUMMARY OF BACKGROUND DATA: .: Postoperative shoulder imbalance (PSI) is still common in Lenke 1 and 2 AIS. This could be due to presence of medial dan lateral shoulder discordance. METHODS: .: 151 patients with Lenke 1 and 2 AIS were recruited. Lenke 1 were subclassified into Lenke 1-ve (PTSB Cobb angle < 15 degrees ) and 1 + ve (PTSB Cobb angle between 15 degrees to 24.9 degrees ). T1 tilt represented "medial shoulder balance" and Radiological Shoulder Height (RSH) represented "lateral shoulder balance". We categorized patients into 3 concordant shoulder pattern types (Medial Balanced/ Lateral Balanced (MBLB), Medial Imbalanced + ve/ Lateral Imbalanced + ve (MI + ve/LI + ve), Medial Imbalanced -ve/ Lateral Imbalanced -ve (MI-ve/LI-ve) and 6 discordant shoulder types. RESULTS: .: The mean age was 16.2 +/- 5.7 years. 81 patients (53.6%) had concordant patterns and 70 patients (46.4%) with discordant patterns. Lateral shoulder imbalance was 35.1% and medial shoulder imbalance was 43.7%. In Lenke 1-ve curves, 35 patients (68.6%) had concordant imbalance with Medial Imbalanced -ve/ Lateral Imbalanced -ve (MI-ve/LI ve) being the commonest (68.6%). In Lenke 1 + ve curves, 33 patients (55.0%) had concordant patterns with Medial Balanced/ Lateral Balanced (MB/LB) being the commonest type (57.6%). In Lenke 2 AIS, 27 patients (67.5%) were discordant with Medial Imbalanced + ve/ Lateral Balanced (MI + ve/LB) being the commonest pattern (44.4%) (p value = 0.002). CONCLUSION: .: 46.4% Lenke 1 and 2 AIS patients had shoulder discordant pattern. This was more prevalent in Lenke 2 curves (67.5%). In Lenke 1-ve curves, MI-ve/LI-ve pattern was the commonest. In Lenke 1 + ve curves, both concordant and discordant groups were almost equal. In Lenke 2 AIS, the most common shoulder pattern was MI + ve/LB pattern. LEVEL OF EVIDENCE: 4. PMID- 30299418 TI - Skeletal Muscle Cell Oxidative Stress As A Possible Therapeutic Target In A Denervation-Induced Experimental Sarcopenic Model. AB - STUDY DESIGN: A basic study using a rodent model of sarcopenia. OBJECTIVE: To elucidate the contribution of oxidative stress to muscle degeneration and the efficacy of antioxidant treatment for sarcopenia using an animal model of neurogenic sarcopenia. SUMMARY OF BACKGROUND DATA: Oxidative stress has been reported to be involved in a number of pathologies, including musculoskeletal disorders. Its relationship with sarcopenia, one of the potential origins of lower back pain, however, is not yet fully understood. METHODS: Myoblast cell lines (C2C12) were treated with H2O2, an oxidative stress inducer, and N-acetyl-L cysteine (NAC), an antioxidant. Apoptotic effects induced by oxidative stress and the antioxidant effects of NAC were assessed by western blotting, immunocytochemistry, and MTT cell viability assays. An animal model of sarcopenia was produced via axotomy of the sciatic nerves to induce muscle atrophy. Twenty four male Sprague-Dawley rats were divided into sham, sham+NAC, axotomy, and axotomy+NAC groups. Rats were provided water only or water containing NAC (1 g/L) for four weeks. The gastrocnemius muscle was isolated and stained with hematoxylin and eosin (H&E) two weeks after axotomy, from which muscle cells were harvested and protein extracted for evaluation. RESULTS: Mitogen-activated protein kinases (MAPKs) were significantly activated by H2O2 treatment in C2C12 cells, which was ameliorated by NAC pretreatment. Furthermore, H2O2 induced apoptosis and death of C2C12 cells, which was prevented by NAC pretreatment. The weight of the gastrocnemius muscle was reduced in the axotomy group, which was prevented by NAC administration. Lastly, although muscle specimens from the axotomy group showed greater reductions in muscle fiber, the oral administration of NAC significantly inhibited amyotrophy via antioxidant effects. CONCLUSIONS: The current in vitro and in vivo study demonstrated the possible involvement of oxidative stress in sarcopenic pathology. NAC represents a potential anti sarcopenic drug candidate, preventing amyotrophy and fatty degeneration. LEVEL OF EVIDENCE: 4. PMID- 30299419 TI - Recognition of Insufficient Competence-Nurses' Experiences in Direct Involvement With Adolescent Children of Cancer Patients. AB - BACKGROUND: A parent's cancer may have disruptive impact on his/her adolescent children. Currently, nurses have been regarded as central actors in direct involvement with patients' minor children. Development of an extended nursing role has become a pertinent issue. OBJECTIVE: Adolescents' needs tend to be overlooked by nurses because of inexperience with this population. The aim of this study was to explore nurses' experiences of direct involvement with these adolescents, to get a deeper understanding about this phenomenon. METHODS: Using a constructivist grounded theory approach, 12 interviews were conducted among Norwegian nurses within the cancer care context. The category insufficient competence was explored through analyzing participants' experiences of direct involvements with adolescents. RESULTS: The recognition of insufficient competence became visible as nurses experienced being involved with a population about whom they held inadequate and limited knowledge. Adolescents were perceived as unpredictable and rejecting nurses' approaches. Consequently, nurses feared involvement and experienced failing on their assignments. After completing more or less failed attempts to establish good relationships with adolescents, the nurses requested for more knowledge and experience in order to support this group. CONCLUSIONS: Nurses are recognizing insufficient competence in direct involvement with adolescents, which calls for extended competence. Because nurses are not the only responsible actors performing in this field, building competence requires a broadened attention at both an individual and organizational level, across several healthcare disciplines, as well as through user participation. IMPLICATIONS FOR PRACTICE: Competence building should be considered in light of organizational frameworks, collective learning possibilities across disciplines, and opportunities for involving adolescents/young adults as user participants. PMID- 30299420 TI - Does the Oral Administration of Ginger Reduce Chemotherapy-Induced Nausea and Vomiting?: A Meta-analysis of 10 Randomized Controlled Trials. AB - BACKGROUND: Preclinical tests in animals have shown that ginger extract can be used to treat chemotherapy-induced nausea and vomiting (CINV); however, research findings in clinical trials have not been conclusive. OBJECTIVE: Through this meta-analysis, we aimed to determine whether ginger could be used to treat CINV, which was interpreted using the PICOS (patient, problem/population, intervention, comparison, outcome, study) framework, with P being patients who underwent chemotherapy; I being 0.5 to 2.0 g/d of Zingiberaceae, Zintoma, dry ginger, ginger capsules, powdered ginger root, Zingiber officinale Roscoe, ginger extract, powdered ginger, 6-gingerol, or shogalos; C being placebo or standard care; and O being the relief, reduction, or improvement of CINV. METHOD: Via systematic literature review, we searched for studies in English from 2000 to 2017 in databases. We conducted a meta-analysis using Comprehensive Meta-analysis 2 on a total of 10 studies with complete data. RESULTS: The odds ratio (OR) of ginger in controlling CINV was 0.71 (95% confidence interval [CI], 0.54-0.94; P = .015). Heterogeneity existed among the samples; therefore, we proceeded with a subgroup analysis and divided nausea and vomiting into acute or delayed. The results revealed that ginger could only reduce acute CINV in patients (OR, 0.60; 95% CI, 0.42-0.86; P = .006), particularly acute vomiting (OR, 0.58; 95% CI, 0.37 0.94; P = .025). CONCLUSIONS: Ginger displayed significant efficacy with regard to controlling CINV in the experimental groups. IMPLICATIONS FOR PRACTICE: Our results could provide a reference for antiemetic methods to treat CINV and facilitate support for more clinical trials in the future to establish relevant guidelines. PMID- 30299421 TI - Association of Time-Varying Rest-Activity Rhythm With Survival in Older Adults With Lung Cancer. AB - BACKGROUND: To the best of our knowledge, this is the first study to examine the relationship of rest-activity rhythm with survival in older adults with lung cancer and to consider variations in rest-activity rhythm over time. OBJECTIVE: The aim of this study was to explore the relationship between rest-activity rhythm variations and survival in 33 older adults with lung cancer by considering rest-activity rhythm as a time-dependent covariate over time. METHODS: In this prospective study with 5 repeated measurements, patients' rest-activity rhythm over 3 days was measured using actigraphy. The rest-activity rhythm was represented using the dichotomy index I (in-bed activity) < O (out-of-bed activity). The median I < O was used as the cutoff point, with an I < O of greater than or equal to 85.59% and less than 85.59% indicating robust and disrupted rest-activity rhythms, respectively. Data were analyzed using the Cox regression model with time-dependent repeated measurements of a covariate. RESULTS: In the time-dependent multivariate Cox model, a disrupted rest-activity rhythm was independently associated with a higher risk of death than was a robust rest-activity rhythm (hazard ratio, 16.05; P=.009). CONCLUSION: A time-varying rest-activity rhythm is incrementally associated with mortality in older adults with lung cancer and represents a rigorous and independent prognostic factor for their survival. IMPLICATIONS FOR PRACTICE: Clinicians may need to pay more attention to the rest-activity rhythms of older adults with lung cancer during disease progression. Future studies should account for the variation in rest activity rhythm over time. PMID- 30299422 TI - Impact of the 2017 Blood Pressure Guidelines by the American Academy of Pediatrics in overweight/obese youth. AB - OBJECTIVES: The aim of this study was to compare the impact of the European Society of Hypertension Guidelines 2016 (ESHG2016) and the American Academy of Pediatrics Guidelines 2017 (AAPG2017) on the screening of hypertension and classification of abnormal left ventricular geometry (ALVG) in overweight/obese youth. METHODS: This study included 6137 overweight/obese youth; 437 had echocardiographic assessment. Hypertension was defined using either ESHG2016 or AAPG2017. ALVG was defined using 95th percentile for age and sex of left ventricular mass index (LVMi) and/or relative wall thickness (RWT) more than 0.38 (juvenile cut-offs) according to ESHG2016 or LVMi more than 51 g/h and/or RWT more than 0.42 (adult cut-offs) according to AAPG2017. RESULTS: Prevalence of youth at a high risk of hypertension was 13% higher using AAPG2017 than ESHG2016. The increase was larger in overweight youth at least 13 years of age (+43%). Using the juvenile cut-offs for ALVG, youth at a high risk of hypertension by ESHG2016 had an odds ratio [95% confidence interval (95% CI)] of 3.03 (1.31-7.05) for left ventricular concentric remodelling (LVcr) and 2.53 (1.43-4.47) for concentric left ventricular hypertrophy (cLVH) as compared with youth with normal LVG. Similarly, in youth at a high risk of hypertension by AAPG2017, the odds ratio for LVcr was 3.28 (1.45-7.41, P < 0.001) and 3.02 (95% CI: 1.73-5.27, P < 0.001) for cLVH. Using the adult cut-offs, no significant difference in ALVG was found with both guidelines. CONCLUSION: The prevalence of overweight/obese youth at a high risk of hypertension increased by 13% comparing AAPG2017 vs. ESHG2016. The juvenile cut-offs for ALVG were more effective than the adult criteria in intercepting individuals with a potentially higher cardiovascular risk. PMID- 30299423 TI - Group B Streptococcal Neonatal and Early Infancy Infections in Iceland 1976 - 2015. AB - BACKGROUND: Despite a risk-based peripartum chemoprophylaxis approach in Iceland since 1996, Streptococcus agalactiae (GBS) remains an important cause of early onset (<7 days, EOD) and late-onset disease (7 days to 3 months, LOD). METHODS: We studied GBS invasive disease in children <1 year in Iceland in 1976-2015. Bacteria (n=98) were characterized by susceptibility to a panel of antimicrobials, capsular serotyping, resistance genes, surface protein and pilus locus profiling, and multilocus sequence typing. RESULTS: Both EOD and LOD increased during the early years, but while EOD subsequently decreased from 0.7/1000 live births in 1991-1995 to 0.2/1000 in 2011-2015, LOD showed a non significant decrease from its peak value of 0.6/1000 in 2001-2005 to 0.4/1000 in 2006-2015. Serotype III was the most frequently found (n=48), represented mostly by the hypervirulent lineage CC17/III/rib/PI-1+PI-2b (62%), but also by CC19/III/rib/PI-1+PI-2a (35%) frequently associated with colonization. Serotype Ia (n=22) was represented by CC23/Ia/eps/PI-2a (68%), and CC7/Ia/bca/PI-1+PI-2b (23%) of possible zoonotic origin. Resistance to erythromycin and clindamycin was increasingly detected in the last years of the study (five out of the nine cases were isolated after 2013), including representatives of a multiresistant CC17/III/rib/PI-2b sublineage described recently in other countries and expressing resistance to erythromycin, clindamycin and streptomycin. CONCLUSIONS: The risk-based chemoprophylaxis adopted in Iceland possibly contributed to the decline of EOD but has had limited effect on LOD. GBS causing neonatal and early infancy invasive infections in Iceland are genetically diverse and the recent emergence of antimicrobial resistant lineages may reduce the choices for prophylaxis and therapy of these infections. PMID- 30299424 TI - Respiratory Microbiota Predicts Clinical Disease Course of Acute Otorrhea in Children With Tympanostomy Tubes. AB - BACKGROUND: Acute otitis media (AOM) is one of the most common childhood infections, generally thought to be caused by ascension of bacteria from the nasopharynx (NP) to the middle ear. Using 16S rRNA-based sequencing, we evaluated the relationship between the NP and middle ear fluid (MEF) microbiota in children with acute otitis media with tympanostomy tubes (AOMT) as a proxy for AOM, and explored whether microbiota profiling predicts natural disease course. METHODS: Microbiota profiles of paired NP and MEF samples of 94 children aged below five years with uncomplicated AOMT were determined. RESULTS: Local diversity (p<0.001) and overall microbiota composition (p<0.001) of NP and MEF samples differed significantly, though paired NP and MEF samples were much more similar than unpaired samples (p<0.001). High qualitative agreement between the presence of individual bacteria in both niches was observed. Abundances of Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus pyogenes, Turicella otitidis, Klebsiella pneumoniae, and Haemophilus spp. were strongly correlated between the two niches. Additionally, P. aeruginosa, S. aureus, T. otitidis and Streptococcus pneumoniae abundance in NP were predictive of the presence of a range of oral types of bacteria in MEF. Interestingly, there was no association between Moraxella catarrhalis in NP and MEF samples, which was highly present in NP but virtually absent in MEF. Finally, the NP microbiota composition could predict duration of AOMT, even better than MEF microbiota. CONCLUSIONS: We observed substantial correlations between paired NP and MEF microbiota in children with AOMT. Our data also suggest that NP microbiota profiling deserves further exploration as tool for future treatment decisions.

PMID- 30299427 TI - Impact of Disease on Amikacin Pharmacokinetics and Dosing in Children. AB - BACKGROUND: Amikacin is widely used to treat severe Gram-negative bacterial infections. Its peak concentration in plasma is associated with treatment efficacy. Amikacin pharmacokinetics (PK) is influenced by disease conditions, in addition to other patient characteristics. In this retrospective study, we evaluated the impact of clinical characteristics and disease condition on amikacin PK in children with burn injuries and those with cancer. METHODS: Amikacin PK data from 66 children with burn injuries and 112 children with cancer were analyzed. A population PK model was developed using the non-linear mixed effects modeling approach. Models were developed using NONMEM 7.3 (ICON Development Solutions, LLC, Ellicott City, MD, USA). Data processing and visualization was performed using R packages. RESULTS: The amikacin PK data was best described by a 2-compartment model. The parameters were estimated with means (95% confidence intervals) as follows: central volume of distribution (V1), 5.70 L (4.64-6.76 L); central clearance (CL), 2.12 L/h (1.79-2.46 L); peripheral volume of distribution (V2), 4.79 L (2.36-7.22 L); distribution clearance (Q), 0.71 L/h (0.25-1.16 L/h). The final model identified the disease condition as a significant covariate, and indicated 55% (28% - 82%) higher CL and 17% (1% - 34%) higher V1 in burn patients compared with cancer patients. Volume of distribution was significantly influenced by age and body weight. Clearance was significantly influenced by age, body weight and creatinine clearance. Using the final PK model, we developed a workflow for selecting optimal dosing strategies for three representative pediatric patient profiles. CONCLUSION: Disease condition was significant in influencing amikacin PK in children. To reach the same target concentrations (64 mg/L peak concentration) with a daily dose plan, burn patients need higher doses than cancer patients. Future investigations are needed to explore the impact of other diseases on amikacin disposition in children, and to prospectively validate the proposed dosing strategy. PMID- 30299428 TI - Pharmacodynamic monitoring of biological therapies in chronic inflammatory diseases. AB - BACKGROUND: Psoriasis, psoriatic arthritis, spondyloarthritis, rheumatoid arthritis, ulcerative colitis and Crohn's disease share similar underlying pathophysiological processes, providing the opportunity to treat the patients using similar biological therapies. Failure of biological treatments due to underexposure can be managed by therapeutic drug monitoring. Adjusting the treatment based on pharmacokinetic monitoring can be further improved by taking pharmacodynamic parameters such as clinical and molecular markers into account. METHODS: Here, we critically evaluate the existing evidence, the hurdles to be taken and the opportunities for a widespread implementation of pharmacodynamic monitoring. RESULTS: Pharmacodynamic monitoring typically is the monitoring of biochemical markers. A pharmacodynamic marker preferably is specific for the pharmacological action of a drug, but most of the time nonspecific pharmacodynamic markers are used, like C-reactive protein and the erythrocyte sedimentation rate. Clinical pharmacodynamic markers typically evaluate physical variables or symptoms. While physician-reported outcomes have been studied for a longer time and often have been shown to correlate well with molecular pharmacodynamic markers and treatment outcomes, the introduction of mobile health or mHealth technologies caused a shift towards patient-reported outcomes, with the associated challenge to consistently reflect the inflammatory state, thereby preventing undertreatment or unnecessary overdosing of patients. CONCLUSIONS: The primary goal of pharmacodynamic monitoring is to optimize the response, but it can also have an impact on safety, costs, patient adherence, etc. Ideally, the constant remote monitoring of patient-reported disease activity is expected to become the standard, facilitated by mHealth technologies. PMID- 30299429 TI - Estimation of unbound carboplatin clearance from total plasma concentrations as a means of facilitating therapeutic drug monitoring. AB - BACKGROUND: Therapeutic drug monitoring of carboplatin is based on its unbound clearance (CLU) determined by Bayesian analysis on unbound (U) concentrations. However, the ultrafiltration of plasma samples presents technical and time constraints. Therefore, the present study aims to estimate CLU using total plasma (P) concentrations. METHODS: U and P concentration data of 407 patients were obtained from two clinical studies in which actual CLU had been determined for each patient. The patients were then split into development (277 patients) and prospective datasets (130 patients). Two approaches were evaluated. PK-model-only approach: a three-compartment pharmacokinetic (PK) model based on U and P concentrations and taking into account the protein binding process was developed. The model with patient covariates was also evaluated. Linear regression approach: an equation (CLU = a.CLP + b) was obtained by linear regression analysis between actual CLU and CLP which is the total plasma clearance obtained by analyzing P concentrations according to a two-compartment PK model. Predictive performance was then assessed within the prospective dataset by estimating CLU from P concentrations using each approach and computing the relative percentage error (PE) between estimated CLU and actual CLU. RESULTS: The linear regression equation was CLU (L/h) = 1.15 CLP (L/h) + 0.13. The mean PE (MPE) between CLU (estimated using the equation) and the actual CLU was +1.2% (ranging from -31% to +33%) and the mean absolute PE (MAPE) was 9.7%. With the three-compartment PK model, the MPE was +2.3% (ranging from -41% to +31%), and the MAPE was 11.1%. Inclusion of covariates in the three-compartment model did not improve the estimation of CLU [MPE: +6.3% (from -33% to +37%); MAPE=11.4%]. CONCLUSIONS: The linear equation gives a relatively good estimation of CLU based on P concentrations, making PK-based carboplatin dose adaptation possible for centers without ultrafiltration facilities. PMID- 30299430 TI - A Short Communication: Pharmacokinetic characteristics and limited sampling strategies for therapeutic drug monitoring of colistin in patients with multidrug resistant Gram-negative bacterial infections. AB - BACKGROUND: Colistin is increasingly used as the last therapeutic option for the treatment of multidrug-resistant, Gram-negative bacterial infections. To ensure safe and efficacious use of colistin, therapeutic drug monitoring (TDM) is needed due to its narrow therapeutic window. This study aimed to evaluate the pharmacokinetic (PK) characteristics of colistin and to guide TDM in colistin treated patients in Korea. METHODS: In a prospective study, we analysed PK characteristics in 15 patients who intravenously received colistin methanesulfonate (CMS) twice per day. CMS doses were adjusted based on renal function of the subjects. The appropriate blood sampling points for TDM were evaluated by analysing the correlations between the PK parameters and the plasma concentrations at each time point. RESULTS: The mean values for the minimum, maximum and average concentrations (Cmin, Cmax and Caverage) of colistin at steady state were 2.29, 5.5 and 3.38 mg/L, respectively. The dose-normalized Cmin, Cmax, Caverage and area under the plasma concentration-time curve from 0 to the last measurable concentration (AUClast) showed negative correlations with the creatinine clearance. The combination of the 0 and 2-hour post-dose plasma concentrations was evaluated as the appropriate sampling point for TDM. Two patients reported nephrotoxic adverse events during colistin administration. CONCLUSIONS: Our study clarifies the PK characteristics of successful colistin treatment using TDM. Further evaluations in a larger patient population are needed to confirm the clinical usefulness of colistin TDM. PMID- 30299431 TI - Anti-Mullerian hormone as a predictor of reproductive potential. AB - PURPOSE OF REVIEW: Anti-Mullerian hormone (AMH), a marker of ovarian reserve, declines over a woman's reproductive lifespan. AMH is highly correlated with a woman's age and number of primordial ovarian follicles, and has been shown to predict time to menopause in women in their 40s. For these reasons, it was assumed that AMH levels could predict a woman's reproductive potential or serve as a 'fertility test'. Recently, studies have sought to determine the association between AMH and fertility. RECENT FINDINGS: Although a small, prospective, time to-pregnancy study of 98 women suggested that an AMH level less than 0.7 ng/ml was associated with lower day-specific probabilities of conception, the follow up, larger cohort did not identify an association with AMH and fecundability. Women with AMH values less than 0.7 ng/ml had similar pregnancy rates after 12 cycles of attempting to conceive as women with normal AMH values after adjusting for age. Four additional studies, including a secondary analysis of the NICHD EAGER trial including over 1200 women confirmed these findings. SUMMARY: Although AMH is a marker of ovarian reserve, existing literature does not support the use of AMH as a marker of reproductive potential in the general population. PMID- 30299432 TI - Anti-mullerian hormone in the pathophysiology and diagnosis of polycystic ovarian syndrome. AB - PURPOSE OF REVIEW: Polycystic ovarian syndrome (PCOS) is the most common cause of chronic anovulation and hyperandrogenism in young women and represents a true public health concern and an economic burden. RECENT FINDINGS: The pathophysiology of PCOS is still not fully understood, but progresses have been made and the relationships between anti mullerian hormone (AMH), follicle stimulating hormone, luteinizing hormone, E2 and androgens have been explored. The follicle excess plays a central role in the syndrome and AMH is definitively a major component of this phenomena. SUMMARY: The aim of this chapter is to present the recent work studying the role of AMH in the pathophysiology of PCOS and to discuss the improvement that serum AMH assay brings in the diagnosis of PCOS. PMID- 30299434 TI - Current clinical applications of antimullerian hormone. AB - PURPOSE OF REVIEW: Determine if literature supports the use of anti-Mullerian hormone (AMH) as a useful biomarker of reproductive potential when cumulative live birth rates (CLBRs) per retrieval are used as the outcome variable. RECENT FINDINGS: Advances in technology used in in-vitro fertilization (IVF) permit the use of single embryo transfer to achieve expected pregnancy success rates. Many IVF cycles result in the creation of more than a single embryo suitable for transfer per oocyte retrieval. Cryopreservation permits subsequent use of other embryos with no loss in total reproductive potential from single retrievals. Therefore, an emerging concept in IVF is the CLBR per retrieval as an indicator of the patient's reproductive potential. Using the total reproductive potential from a single retrieval may help patients decide on IVF. As such, any predictor of success that relies upon the live birth rate for a single transfer, as opposed to CLBR per retrieval, is inadequate to estimate the true reproductive potential for patient. AMH has been proposed as a biomarker for reproductive potential, but most studies have correlated an AMH value to a single embryo transfer. SUMMARY: A more appropriate way to use AMH levels may be to correlate the AMH with CLBR per retrieval. AMH may thus prove to be a useful biomarker when counseling patients about what to expect from their treatment. PMID- 30299433 TI - The role of antimullerian hormone in assessing ovarian damage from chemotherapy, radiotherapy and surgery. AB - PURPOSE OF REVIEW: Iatrogenic ovarian damage can occur after chemotherapy, radiotherapy and surgery for cancer as well as for non-malignant conditions. This review describes the effects of such treatment on antimullerian hormone (AMH) and the implications of the fall in AMH in relation to ovarian function and fertility, especially in the era of improved fertility preservation strategies. RECENT FINDINGS: The risk of gonadotoxicity differs between chemotherapy regimens. There is growing evidence that pretreatment AMH has prognostic significance for the degree of fall in AMH after treatment, the reversibility of ovarian damage and risk of premature ovarian insufficiency. The accuracy of prediction increases when age is coupled with AMH. The adverse effect of removal of endometriomas is increasingly clear, and AMH pre and post surgery useful is assessing the degree of damage to the ovary. The implications of low AMH after such treatment on natural fertility and reproductive lifespan are less clear. Apart from treatment effects, there are other coexisting conditions that can affect AMH which needs to be taken into consideration during interpretation of AMH before and after treatment. SUMMARY: A fall in AMH in women after gonadotoxic treatment has been consistently described, with variable recovery, the accurate interpretation and clinical application of post-treatment AMH level on reproductive lifespan and fertility prediction needs to be studied in future larger prospective studies with longer follow-up. PMID- 30299435 TI - Use of bone turnover markers in the management of osteoporosis. AB - PURPOSE OF REVIEW: Osteoporosis is a common public health problem that is often undertreated and underdiagnosed. The clinical management of osteoporosis is often reactionary to devastating fracture events. Bone turnover markers may improve the ease and rapidity at which osteoporosis is monitored and treated. Bone turnover markers are biochemical byproducts of bone formation or bone resorption. The clinical use of bone turnover markers is limited by significant preanalytical variability. Effective interpretation of bone turnover markers requires a detailed understanding of the variables that can affect their responses to osteoporosis treatment and monitoring. RECENT FINDINGS: Progress is continuously being made on the standardization of bone turnover markers. The literature on the response of bone turnover markers to unique clinical situations is expanding. Data for evidence-based reference intervals for bone turnover markers has increased. Variables that affect the appropriate timing of lab draws like diurnal variation, postprandial status, exercise and alcohol use have been described. Studies examining the expected response of bone turnover markers to treatments of osteoporosis and other medications that affect bone health continue to increase. SUMMARY: Bone turnover markers have clinical utility in the comprehensive evaluation of osteoporosis. When interpreted with caution and with a good understanding of their natural variability, bone turnover markers provide information that supplements osteoporosis management and provides useful clinical information about conditions that alter bone turnover.

AB - OBJECTIVE: Since the first evaluation in 2011 of the "Healthy Eating and Ecological Production Program in School Meals of Asturias", the improvement of the menus has been analyzed in terms of frequencies in the food group offer. The objective of this study was to evaluate the culinary quality of the menus, in order to complement this analysis. METHODS: Transversal descriptive study with a sample for convenience of the 243 Primary Education centers of Asturias, that is, 195 in the 2015-16 academic year.. A monthly menu was requested to all the centers and in case of not receiving a response, a search was made on the Internet. Minimum criteria were defined to comply with frequencies, variety and recipes for each food group. The menus were analyzed every day and the differences between the menus cooked on site vs catering, as well as between public versus private / concerted centers. The data analysis was performed with the SPSS program and the differences between percentages of compliance with the Chi square test. RESULTS: 195 menus were analyzed (80.2%), obtaining high percentages of compliance in all the criteria (over 80%), except in the variety of carbohydrates (27.7%), fruit (22.1%). %), processed meat (13.9%), vegetable offer as first course (6.1%) and animal protein in the first course (2.6%). CONCLUSIONS: The general compliance of the recommendations with respect to variety and different recipes in the schools is very adequate, especially in those of public ownership and with own kitchen type.

PMID- 30299438 TI - Global-scale phylogenetic linguistic inference from lexical resources. AB - Automatic phylogenetic inference plays an increasingly important role in computational historical linguistics. Most pertinent work is currently based on expert cognate judgments. This limits the scope of this approach to a small number of well-studied language families. We used machine learning techniques to compile data suitable for phylogenetic inference from the ASJP database, a collection of almost 7,000 phonetically transcribed word lists over 40 concepts, covering two thirds of the extant world-wide linguistic diversity. First, we estimated Pointwise Mutual Information scores between sound classes using weighted sequence alignment and general-purpose optimization. From this we computed a dissimilarity matrix over all ASJP word lists. This matrix is suitable for distance-based phylogenetic inference. Second, we applied cognate clustering to the ASJP data, using supervised training of an SVM classifier on expert cognacy judgments. Third, we defined two types of binary characters, based on automatically inferred cognate classes and on sound-class occurrences. Several tests are reported demonstrating the suitability of these characters for character-based phylogenetic inference.

AB - Using Dual-Frequency Identification Sonar (DIDSON), fishery acoustic observation data was collected from the Ocqueoc River, a tributary of Lake Huron in northern Michigan, USA. Data were collected March through July 2013 and 2016 and included the identification, via technology or expert analysis, of eight fish species as they passed through the DIDSON's field of view. A set of short DIDSON clips containing identified fish was curated. Additionally, two other datasets were created that include visualizations of the acoustic data and longer DIDSON clips. These datasets could complement future research characterizing the abundance and behavior of valued fishes such as walleye (Sander vitreus) or white sucker (Catostomus commersonii) or invasive fishes such as sea lamprey (Petromyzon marinus) or European carp (Cyprinus carpio). Given the abundance of DIDSON data and the fact that a portion of it is labeled, these data could aid in the creation of machine learning tools from DIDSON data, particularly for invasive sea lamprey which are amply represented and a destructive invader of the Laurentian Great Lakes.

PMID- 30299441 TI - Isofraxidin targets the TLR4/MD-2 axis to prevent osteoarthritis development. AB - Osteoarthritis (OA) is a major cause of joint pain and disability, resulting in large socioeconomic costs worldwide. Isofraxidin (ISO), a bioactive coumarin compound isolated from the functional foods Siberian ginseng and Apium graveolens, exerts anti-inflammatory effects in a variety of diseases. However, no studies have reported the protective effects of ISO against OA development. Accordingly, this study aimed to assess the therapeutic effect of ISO in human OA chondrocytes, and in a mouse model of OA induced by destabilisation of the medial meniscus (DMM). In vitro, lipopolysaccharide (LPS)-induced overproduction of nitric oxide (NO), prostaglandin E2 (PGE2), tumour necrosis factor-alpha (TNF alpha) and interleukin-6 (IL-6) was decreased by ISO pre-treatment. Furthermore, ISO attenuated the increased expression of inflammatory enzymes, including inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), in response to LPS stimulation. Meanwhile, LPS-induced extracellular matrix (ECM) degradation was also reversed by ISO treatment. Mechanistically, ISO competitively inhibited Toll-like receptor 4 (TLR4)/myeloid differentiation protein-2 (MD-2) complex formation, and thus TLR4/nuclear factor kappa B (NF-kappaB) signalling cascades. In vivo, ISO treatment not only prevented the calcification and erosion of cartilage, as well as the thickening of subchondral bone, but also reduced the serum levels of inflammatory cytokines in the mouse OA model. Taken together, these data suggest that ISO has potential in the treatment of OA.

AB - Inspired by natural photosynthesis in an organized assembly, compact H2-evolving molecular devices, which tether sensitizer and catalyst modules in one single molecule, present an opportunity to overcome the diffusion limit required for multi-component molecular systems, and increase intramolecular electron transfer rates from the photoactivated unit to the catalytic center to improve H2-evolving efficiency. Thereinto absolutely noble-metal free H2-evolving molecular devices are of particular interest because they don't contain precious and scarce noble metal based components. This Frontier article focuses specifically on the recent advances in the design, synthesis, and photocatalytic properties of all-abundant element molecular devices for photoinduced H2 generation via intramolecular processes. Some challenges and suggestions for future directions in this field are also illustrated.

AB - The sparse but functionally essential post-translational collagen modification 5 hydroxylysine can undergo further transformations, including crosslinking, O glycosylation, and glycation. Dynamic nuclear polarization (DNP) and stable isotope enriched lysine incorporation provide sufficient solid-state NMR sensitivity to identify these adducts directly in skin and vascular smooth muscle cell extracellular matrix (ECM), without extraction procedures, by comparison with chemical shifts of model compounds. Thus, DNP provides access to the elucidation of structural consequences of collagen modifications in intact tissue. PMID- 30299446 TI - Efficient synthesis of organic thioacetates in water. AB - Thioacetates as precursors of thiols are interesting starting points for synthesizing other organosulfur compounds. Herein, we propose a simple, efficient and fast method to obtain organic thioacetates using water as a solvent. Taking into account the great attention that has been paid toward environmentally friendly synthetic procedures in the past decades, we prove the role and the strength of the thioacetate anion as a nucleophile for nucleophilic displacement reactions in an aqueous medium. The reactions were carried out under pH control, to prevent the decomposition of the mesylate starting materials, using potassium carbonate as a safe and mild base. A simple work up allows products to be obtained with excellent yield and acceptable purity. PMID- 30299450 TI - Synergistic actions of mixed small and large pores for capillary absorption through biporous polymeric materials. AB - Water absorption in porous media is an important process involved in numerous materials for various applications, such as in the building industry, food processing and bioengineering. Designing new materials with appropriate absorption properties requires an understanding of how absorption behavior depends on both the material's morphology and the properties of the solid matrix, i.e. hydrophilic/hydrophobic nature and swelling/deformation properties. Although the basic principles of imbibition are well-known for simple porous systems, much less is known about absorption in complex porous systems, in particular those containing several coexisting porous phases, such as wood for example. Here, water absorption is studied for model porous organic materials exhibiting several degrees of hydrophobicity and two pore size levels, either as monoporous materials (large or small pores) or as biporous materials (mixed large and small pores). The interconnected biporous structure is designed via a double porogen templating approach using cubic sodium chloride particles as templates for the generation of the larger pore size (250-400 MUm) and i-PrOH as a porogenic solvent for the smaller pore size (2-5 MUm). While absorption for the small pore material is well described by the classical Washburn theory, the large pore material shows a drastic reduction in the imbibition rate. This behavior is attributed to the slow breakthrough mechanism for the water interface at sharp edge connections between pores. Remarkably, this slow regime is suppressed for the biporous material and the imbibition rate is even higher than the sum of rates obtained for its monoporous counterparts, which highlights the synergistic action of mixed small and large pores. PMID- 30299451 TI - Target Validity and the Hierarchy of Study Designs. AB - In recent years, increasing attention has been paid to problems of external validity, specifically to methodological approaches for both quantitative generalizability and transportability of study results. However, most approaches to these issues have considered external validity separately from internal validity. Here, we argue that considering either internal or external validity in isolation may be problematic. Further, we argue that a joint measure of the validity of an effect estimate with respect to a specific population of interest may be more useful: we call this proposed measure target validity. In this work, we introduce and formally define target validity as the total difference between the true causal effect in the target population and the estimated causal effect in the study sample. We illustrate this measure with a series of examples and show how this measure may help us to think more clearly about comparisons between experimental and non-experimental research results. Specifically, we show that even perfect internal validity does not ensure that a causal effect will be unbiased in a specific target population. PMID- 30299452 TI - Life expectancy with and without dementia: a population-based study of dementia burden and preventive potential. AB - Reliable population estimates of life-expectancy with dementia are required for shaping health care policy. 10,348 persons from the population-based Rotterdam Study were followed from 1990-2015 for dementia and death. We created multi-state lifetables, and assessed the effect of postponing disease onset. During 120,673 person-years, 1,666 persons developed dementia, and 6,150 died. Overall life expectancy of women ranged from 18.0 years (95% confidence interval:17.8-18.2) at age 65 to 2.3 years (2.2-2.3) at age 95. Of total life-expectancy at age 65, 5.7%, i.e. 1.0 year (1.0-1.1), was lived with dementia, increasing with age to 42.1% (1.0 year,0.9-1.0) of life-expectancy at age 95. For men, overall life expectancy ranged from 15.6 years (15.4-15.9) at age 65 to 1.8 years (1.7-1.8) at age 95, of which 3.7% (0.6 year,0.5-0.6) and 35.3% (0.6 year,0.5-0.7) was lived with dementia, respectively. Postponing dementia onset by 1-3 years resulted in 25-57% reductions in years lived with dementia. Survival after dementia diagnosis ranged from 6.7 (95%CI 5.3-8.1) years when diagnosed before age 70, to 2.6 years (2.3-2.9) >90 years. Dementia places a large burden on individuals and society in terms of healthy life-years lost, but this is potentially highly amendable by preventive interventions at the population level. PMID- 30299453 TI - Detection and prevention of adverse drug reactions in multi-morbid older patients. AB - Adverse drug reactions (ADRs) are a recognised unintentional form of iatrogenic harm, which commonly occur in older adults who have high levels of multi morbidity and associated polypharmacy. Previous studies estimate that at least one in 10 hospitalised older patients will experience an ADR. While recent research indicates that this could be as high as 39% in hospitalised multi morbid, older adults, up to two-thirds of these ADRs can be considered preventable and therefore potentially avoidable. In addition to increasing patient morbidity and contributing to avoidable mortality, there is an associated cost implication with ADR occurrence. This commentary summarises current mainstream research in terms of ADR detection, prediction and prevention in multi morbid older patients. At present, the biggest barrier to understanding and comparing ADRs in the literature is the large heterogeneity that exists in the population and study methods. Furthermore, there is the lack of standardised universally accepted methodology for ADR prediction, detection, causality assessment and subsequent prevention in older people. Standard available methods of ADR prediction applied to a heterogeneous multi-morbid population are generally unsatisfactory. Without an instrument that consistently and reliably predicts ADR risk in a reproducible manner, ADR prevention in multi-morbid older patients is challenging. Further attention should be focused on the culprit drugs that commonly lead to major ADRs in older multi-morbid hospitalised patients with polypharmacy. Risk associated with particular drug classes may possibly predict ADR occurrence better than patient characteristics alone. Current research is examining this drug class focus for ADR prevention in multi-morbid older people. PMID- 30299454 TI - Reductions in Cigarettes per Day and Mortality Among Older Adults in The United States. AB - Many smokers do not quit but instead reduce the number of cigarettes that they smoke per day (CPD) over their lifetime, yet the associations of such changes in CPD with health risks are unclear. We examined the association of changes in CPD with subsequent mortality (2004-2011) among 253,947 participants of the NIH-AARP Diet and Health Study. We identified cigarette smokers who quit, decreased, maintained, or increased their CPD between ages 25-29 and 50-59 using a questionnaire assessing smoking history in 2004-2005. Hazard ratios (HR) and 95% confidence intervals (CI) were from multivariable-adjusted Cox proportional hazards regression. Relative to never smokers, smokers who maintained a consistent CPD had 2.93 times (95%CI: 2.82, 3.05) higher all-cause mortality risk, with still higher risks observed in participants who increased their CPD (HR: 3.37, 95%CI: 3.23, 3.52). Risks were lower among participants who decreased their CPD (HR: 2.38, 95%CI: 2.25, 2.52) or quit smoking (HR for quitting between 30-39 years: 1.32, 95%CI: 1.25, 1.39). Similar patterns were observed for smoking related causes of death, with particularly strong associations for lung cancer and respiratory disease. Reductions in CPD over the lifetime meaningfully decrease mortality risk. But cessation provides a larger benefit than even large declines in CPD.

PMID- 30299456 TI - Host Preference and Olfaction in Drosophila mojavensis. AB - Many organisms live in complex environments that vary geographically in resource availability. This environmental heterogeneity can lead to changes within species in their phenotypic traits. For example, in many herbivorous insects, variation in host plant availability has been shown to influence insect host preference behavior. This behavior can be mediated in part through the insect olfactory system and the odor-evoked responses of olfactory receptor neurons (ORNs), which are in turn mediated by their corresponding odorant receptor genes. The desert dwelling fly Drosophila mojavensis is a model species for understanding the mechanisms underlying host preference in a heterogeneous environment. Depending on geographic region, one to multiple host plant species are available. Here, we conducted electrophysiological studies and found variation in responses of ORNs to host plant volatiles both within and between 2 populations-particularly to the odorant 4-methylphenol. Flies from select localities within each population were found to lack a response to 4-methylphenol. Experiments then assessed the extent to which these electrophysiological differences were associated with difference in several odor-mediated behavioral responses. No association between the presence/absence of these odor-evoked responses and short range olfactory behavior or oviposition behavior was observed. However, differences in odor induced feeding behavior in response to 4-methylphenol were found. Localities that exhibit an odor-evoked response to the odorant had increased feeding behavior in the presence of the odorant. This study sets the stage for future work examining the functional genetics underlying variation in odor perception. PMID- 30299457 TI - Reducing the Number of Unnecessary Thyroid Biopsies While Improving Diagnostic Accuracy: Toward the "Right" TIRADS. AB - Context: The prevalence of thyroid nodules in the general population is increasingly high, and at least half of those biopsied prove to be benign. Sonographic risk-stratification systems are being proposed as "rule-out" tests that can identify nodules that do not require fine-needle aspiration (FNA) cytology. Objective: To comparatively assess the performances of five internationally endorsed sonographic classification systems [those of the American Thyroid Association, the American Association of Clinical Endocrinologists, the American College of Radiology (ACR), the European Thyroid Association, and the Korean Society of Thyroid Radiology] in identifying nodules whose FNAs can be safely deferred and to estimate their negative predictive values (NPVs). Design: Prospective study of thyroid nodules referred for FNA. Setting: Single academic referral center. Patients: Four hundred seventy-seven patients (358 females, 75.2%); mean (SD) age, 55.9 (13.9) years. Main Outcome Measures: Number of biopsies classified as unnecessary, false-negative rate (FNR), sensitivity, specificity, predictive values, and diagnostic ORs for each system. Results: Application of the systems' FNA criteria would have reduced the number of biopsies performed by 17.1% to 53.4%. The ACR Thyroid Imaging Reporting and Data System (TIRADS) allowed the largest reduction (268 of 502) with the lowest FNR (NPV, 97.8%; 95% CI, 95.2% to 99.2%). Except for the Korean Society of Thyroid Radiology TIRADS, all other systems exhibited significant discriminatory performance but produced significantly smaller reductions in the number of procedures. Conclusions: Internationally endorsed sonographic risk stratification systems vary widely in their ability to reduce the number of unnecessary thyroid nodule FNAs. The ACR TIRADS outperformed the others, classifying more than half the biopsies as unnecessary with a FNR of 2.2%.

PMID- 30299459 TI - Impacts of various storage periods on egg quality, hatchability, post-hatching performance, and economic benefit analysis of two breeds of quail. AB - The effect of storage period on hatching and post-hatching performance of two quail breeds (brown Japanese quail (BJQ) and French white quail (FWQ)) was investigated using 940 eggs from each breed. Eggs were divided into four equal groups (235 eggs each), in each group. A total number of 210 eggs were used for incubation (with three replicates, 70 eggs each) and additional 25 eggs served as samples for egg quality parameters, each group was kept for special storage period. The first group was incubated on the same day of collection (zero day storage). Whereas the second, third, and fourth groups were stored for 4, 7, and 10 d, respectively. Increasing the storage period more than 4 d significantly decreased the relative albumen weight, yolk index, total hatchability, and fertile eggs but significantly increased the relative yolk/albumen ratio, absolute and relative egg weight loss. Moreover, FWQ eggs exhibited higher (P < 0.05) hatchability compared to BJQ eggs after 10 d of storage and yielded heavier chicks (P < 0.05) after all storage periods. The economic analysis indicated that the storage costs for FWQ eggs were significantly greater than those of BJQ at a 0 d of storage (2.42 vs. 4.81 US cent (c); P < 0.05). Furthermore, the total costs for BJQ eggs were significantly lower than the total costs for FWQ eggs (3.0 vs. 7.0 c; P < 0.05). With respect to profitability, the total return represented by selling the chicks was calculated at 5.43 c for BJQ and 9.01 c for FWQ. The net return estimated for FWQ was significantly greater than that of BJQ (3.0 vs. 2.0 c; P < 0.05). However, the hatchability loss for FWQ was significantly greater than that of BJQ over different storage periods.

AB - This study was to determine the effects of dietary Zn-methionine (Zn-Met) supplementation on the laying performance, egg quality, antioxidant capacity, and serum parameters of laying hens. Jingh ong-1 strain laying hens (n = 720, 49 wk of age) were randomly assigned to 6 treatments with 6 replications of 20 birds. The control was fed a basal diet supplemented with 80 mg of Zn/kg as Zn sulphate of diet and the 5 groups were fed a basal diet supplemented with 20, 40, 60, 80, and 100 mg of Zn/kg as Zn-Met of diet for 10 wk, respectively. At the terminal experiment, there were significant differences between control and 80 mg/kg Zn Met group in feed intake (P < 0.05) and feed conversion ratio (FCR) (P < 0.01). Egg weight (P < 0.05) and albumen height (P < 0.01) reduced and were not significantly influenced by supplemental 80 mg/kg Zn-Met group until being stored 15 d as compared to the control. Zn-Met group in 100 mg/kg significantly increased haugh unit (P < 0.05) as compared to the control. The activity of MDA in serum had a linear decrease in 20 to 100 mg/kg Zn-Met. The activity of CAT in liver and GSH-Px in serum had quadratic effects in response to the Zn-Met treatments. Compared to the control, 60 mg/kg Zn-Met group increased the T-AOC, GSH-Px activity in serum (P < 0.01), and the T-AOC (P < 0.05), CuZnSOD (P < 0.01), GSH-Px (P < 0.01) activity in liver. Compared with the control, the concentration of serum ionic Ca in 80, 100 mg/kg Zn-Met treatments reduced (P < 0.01) significantly while the activity of serum alkaline phosphatase (AKP) increased in the Zn-Met groups of 40, 60, and 80 mg/kg (P < 0.01), and 100 mg/kg (P < 0.05). In conclusion, dietary Zn-Met supplementation at 60 to 80 mg/kg had more positive effects on performance, egg quality, and antioxidant capacity in laying hens as compared to 80 mg/kg ZnSO4. PMID- 30299461 TI - Engineering of the upper hinge region of human IgG1 Fc enhances the binding affinity to FcgammaIIIa (CD16a) receptor isoform. AB - The interaction between antibodies and Immune cells surface FcgammaRIIIa (CD16a) receptor triggers a variety of immune responses including antibody-dependent cell mediated cytotoxicity, antibody neutralization, phagocytosis, inflammation and tissue injury. Recent studies showed that IgG1 upper hinge region and FcgammaRs polymorphism play a major role in the interaction with Fcgamma receptors and in the stability of the immune complex hence, in mounting strong inflammatory response. To further investigate this issue, we developed a tool box of IgG1 Fc isoforms to depict the affinity between mutated IgG1 Fc regions and extracellular domain variants (V158F) of CD16a. Our strategy consisted of designing different random upper-hinge mutated variants of IgG1 Fc domain, reproducing the naturally occurring two variants of CD16a and producing all of them as recombinant fusion proteins in Pichia Pastoris. The interactions were assayed using the Surface Plasmon Resonance (Biacore) method along with an in silico analysis to identify the major interaction and key residues that underline the affinity between the Fc region and CD16a variants. Our data showed that the affinity of the Fc region to the CD16a is strongly correlated to polar interactions. This molecular engineering approach yielded an IgG1Fc mutant with enhanced binding affinity to CD16a F158 variant. PMID- 30299462 TI - Assessing the effect of patient to provider language discordance on depression screening utilizing the Patient Health Questionnaire: an epidemiology study. AB - Background: As depression screening becomes a standard in primary care, the question remains of how effective and equitable screening can be implemented to avoid cultural and language-related disparities. Methods: In this retrospective cohort study, rates of depression screening were compared for 3626 adult patients at a family medicine residency-based health centre in Pennsylvania, USA. The PHQ 2/PHQ-9 modality was verbally administered by nursing staff at the time of patient intake as part of a universal screening initiative. Chi-square analysis was used to determine the univariate associations of performed depression screening with variables of language, ethnicity, gender and number of office visits. A binary logistic regression was then performed to measure whether univariate associations remain significant after correction for other variables. Results: Chi-square analysis revealed significant differences in screening based on univariate associations of language, gender and number of office visits. No significant difference was found for age or ethnicity. Binary logistic regression revealed the following odds ratio of being screened for depression for each variable: Spanish language (OR = 0.694, CI = 0.559 to 0.862), female gender (OR = 1.155, CI = 1.005 to 1.328) and office visit frequency of three or more office visits per year (OR = 2.103, CI = 1.835 to 2.410). Conclusions: Spanish-speaking adults were significantly less likely to be screened for depression than their English-speaking counterparts. Women were more likely to be screened than men, and the odds of screening increased with more frequent exposure to the office. Future studies should be directed at validating these findings in multiple clinical settings. PMID- 30299463 TI - Perceived Properties Are Not Free-Floating. PMID- 30299464 TI - Acute Effects of the Translocator Protein (TSPO) Drug Ligand FGIN-1-27 on Serum Testosterone and LH Levels in Male Sprague Dawley Rats. AB - We reported that FGIN-1-27 (N, N-dihexyl-2-(4-fluorophenyl)indole-3-acetamide, FGIN), a synthetic ligand for translocator protein (TSPO, 18 kDa), increased serum testosterone levels in young and aged Brown Norway rats after its administration daily for 10 days. It is not known, however, how soon after treatment with FGIN serum testosterone rises, how long levels remain elevated after cessation of treatment, or whether the drug acts solely through TSPO. Adult Sprague Dawley male rats received a single ip dose of FGIN (1mg/kg BW). Serial blood samples were collected and serum testosterone and LH were assessed hourly throughout 24 hours. Testosterone concentration was maximal by 3 hours, remained significantly higher than the controls at 10 hours, and returned to the control level by 24 hours. Consistent with the in vivo study, culturing isolated Leydig cells with either FGIN (40MUM) or LH (0.1ng/ml) resulted in significantly increased testosterone production by 30 mins, and the stimulatory effects persisted through 48 hours. At a very early (15 min) treatment time, however, FGIN significantly increased testosterone production but LH had not yet done so. Surprisingly, in vivo treatment with FGIN not only increased serum testosterone but also serum LH concentration, raising the possibility that FGIN may increase serum testosterone concentration by dual mechanisms. PMID- 30299465 TI - Detected Objects, Perceived Properties. PMID- 30299466 TI - Seasonal variations in extracellular enzymatic activity in marine snow-associated microbial communities and their impact on the surrounding water. AB - Seasonal changes of microbial abundance and associated extracellular enzymatic activity in marine snow and in seawater were studied in the northern Adriatic during a three-year period. Marine snow was present during the entire period of investigation, although in higher concentrations during summer than during winter. Microorganisms densely colonized marine snow and aggregate-associated enzymatic activity was substantially higher (up to 105 times) than in seawater. Alkaline phosphatase activity (APA) and aminopeptidase activity in marine snow showed seasonal variations with higher values in late spring-summer than in autumn-winter, probably in response to changes in the quantity and quality of organic matter. The highest cell-specific bacterial activity was found for phosphatase, followed by peptidase, and the lowest was for glucosidases. Differential hydrolysis of marine snow-derived organic matter points to the well known phosphorus limitation of the northern Adriatic and indicates preferential utilization of phosphorus- and nitrogen-rich organic compounds by microbes, while hydrolysis of polysaccharides seemed to be less important. In oligotrophic conditions during summer, organic matter released from marine snow might represent a significant source of substrate for free-living bacteria in seawater. For the first time microorganisms producing APA in marine snow were identified, revealing that dense populations of bacteria expressed APA, while cyanobacteria did not. Cyanobacteria proliferating in marine snow could benefit from phosphorus release by bacteria and nanoflagellates. PMID- 30299467 TI - A dietary carbohydrase blend improved intestinal barrier function and growth rate in weaned pigs fed higher fiber diets. AB - The objective of this study was to evaluate the effects of dietary xylanase (X) and a carbohydrase enzyme blend (EB: cellulase, beta-glucanase, and xylanase) on nutrient digestibility, intestinal barrier integrity, inflammatory status, and growth performance in weaned piglets fed higher fiber diets. A total of 460 pigs (6.43 +/- 0.06 kg BW; F25 * 6.0 Genetiporc) were blocked by initial BW and pens (n = 12 per treatment) were randomly assigned to 1 of 4 dietary treatments. The diets included a higher fiber unsupplemented control diet (CON) and the CON supplemented with 0.01% X, 0.01% EB, or both enzymes, arranged in a 2 * 2 factorial. The diets were based on corn, soybean meal, corn distillers dried grains with solubles (DDGS), and wheat middlings. Pigs had 7 d to adapt to the environment and consumed the same commercial diet. Pigs were fed the experimental diets for 28 d with free access to feed and water. Body weight and feed disappearance were recorded weekly. One pig with BW closest to the pen average from each pen was selected and moved to metabolism crates on day 16 and intragastric gavaged a solution of lactulose and mannitol on day 22 followed by 12-h urine collection. Feces were collected from day 23 to 25. Intestinal tissues and mucosal scrapings were collected on day 28. Data were analyzed using PROC MIXED of SAS (9.4). Xylanase, EB, and their interaction were fixed effects and block was a random effect. The EB, but not X, increased pig BW and improved ADG over 28 d (P < 0.05). Neither carbohydrase impacted ADFI, G:F, or apparent total tract digestibility (ATTD) of DM, GE, or CP. The EB improved ATTD of ADF (32.45 vs. 26.57%; P < 0.01), but had no effect on NDF. Unexpectedly, X reduced ATTD of NDF and ADF (P < 0.01). The EB reduced urinary lactulose:mannitol and increased ileal claudin-3 mRNA abundance (P < 0.05), indicating improved small intestinal barrier integrity. There was a X * EB interaction on ileal secretory immunoglobulin A (sIgA) concentration (P < 0.05); in the absence of X, EB decreased sIgA compared to CON, but this effect disappeared in the presence of X. The EB also reduced ileal IL-22 mRNA abundance (P < 0.05), probably indicating decreased immune activation. In conclusion, EB but not X enhanced growth rate of weaned pigs fed higher fiber diets, which may be partly explained by the improved small intestinal barrier integrity and reduced immune activation, rather than improvement in nutrient digestibility. PMID- 30299469 TI - Effect of familiarity and mixing method on gestating sow welfare and productivity in large dynamic groups. AB - The objectives of this study were twofold: first, to investigate the effects of sow familiarity prior to mixing into a larger dynamic group of gestating sows and, second, to examine the impact of how the sows entered the pen during this mixing event. The cohort of sows was either familiar with each other because of premixing (PMIX) or unfamiliar (UMIX). This PMIX or containment of sows in a stall (UMIX), occurred from weaning until the sows were mixed into the large gestation pen 8 d later. The cohort of incoming sows was introduced either as a batched unit (BAT) or new sows were introduced into the dynamic group singly (IND) though the electronic sow feeder. Lesion severity and quantity score, lameness, and body condition score (BCS) were tracked throughout the entire gestation period for 213 sows. Overall, there was little effect of the treatment but a strong impact of parity on the outcomes. Younger animals had significantly higher risk for lesions (P < 0.001) and higher risk for more severe lesions (P < 0.001) than higher parity animals. Lower parity had an association with the risk of lameness (P < 0.05), but it had no significant effect on BCS (P > 0.05). The risk of lameness increased on days 15 and 62 compared to weaning (P < 0.001). Risk of low BCS decreased on days 62 and 113 relative to scores at weaning (P < 0.001). A degree of familiarity by day interaction was present for lesion quantity (P < 0.001) and lesion severity (P < 0.001). The risk of more lesions was higher in the premixed groups before going into the dynamic group, but equilibrated with the unmixed group after day 11, 3 d in the large dynamic pen. The highest risk for the greatest quantity of lesions peaked at day 11 then declined, but never reached the lowest level again which was measured at weaning. Despite the variability in the welfare measures, there was no significant impact of treatment or parity on sow productivity. In conclusion, our data demonstrate that a period of premixing sows and varying the method of entering sows into the pen did not have a long-term impact on the welfare of the sows or on their productivity. PMID- 30299468 TI - Prevalence and risk factors of zygotic splitting after 937 848 single embryo transfer cycles. AB - STUDY QUESTION: What is the prevalence of multiple pregnancy with zygotic splitting after single embryo transfer (SET)? SUMMARY ANSWER: The prevalence of multiple pregnancy with zygotic splitting after SET was 1.36%. WHAT IS KNOWN ALREADY: In 2008, the Japan Society of Obstetrics and Gynaecology (JSOG) recommended the adoption of SET to reduce multiple births. Since then, to improve the clinical pregnancy rate, elective SET using blastocyst transfer and frozen warmed ET has increased. Blastocyst culture and zona pellucida manipulation, including ICSI and AH, have been widely reported as risk factors for monozygotic twinning. However, all these studies may have included cases with dizygotic pregnancies produced by a transferred embryo and a spontaneous conception. STUDY DESIGN, SIZE, DURATION: A retrospective observational study was performed, based on 937 848 SET cycles in registered ART data from the JSOG between 2007 and 2014. The study was approved by the Registration and Research Subcommittee of the JSOG and Juntendo University Ethics Committee. PARTICIPANTS/MATERIALS, SETTING, METHODS: To identify possible factors affecting the prevalence of zygotic splitting, we identified pregnancies, in which the number of foetuses exceeded the number of gestational sacs (GSs), to restrict our analysis to 'true' zygotic splitting. Multiple logistic regression analysis was performed using singleton pregnancy after SET, as control. P < 0.05 was considered statistically significant. MAIN RESULTS AND THE ROLE OF CHANCE: Fresh and frozen-warmed SET produced 276 934 clinical pregnancies (29.5%/SET), including 4310 twins (1.56% of pregnancies) and 109 triplets (0.04% of pregnancies). Based on sex analysis of dichorionic twins after SET, the prevalence of multiple pregnancy with zygotic splitting was 1.36%. Statistical analysis revealed that compared to singleton pregnancies zygotic splitting pregnancies were associated with frozen-warmed ET cycles (odds ratio [OR] = 1.34; 95% CI: 1.16-1.55), blastocyst culture (OR = 1.79; 95% CI: 1.54-2.09) or AH (OR = 1.21; 95% CI: 1.08-1.35). In fresh ET cycles, the prevalence rate of zygotic splitting pregnancy after single blastocyst transfer was significantly higher than that after SET cycles with cleavage embryos (OR = 2.20; 95% CI: 1.83-2.66). However, no significant difference in ovarian stimulation and fertilization methods was recognized. LIMITATIONS, REASONS FOR CAUTION: In the current Japanese ART registry system, data regarding frozen-warmed ET do not include information about ovarian stimulation and fertilization methods. Registration for AH only began in 2010. There is no way of validating if data submitted by clinics is correct. WIDER IMPLICATIONS OF THE FINDINGS: Clinicians should consider whether to counsel couples about the small increase in the risk of zygotic splitting associated with some embryo manipulations.

PMID- 30299470 TI - Kit-independent mast cell adhesion mediated by Notch. AB - Kit/CD117 plays a crucial role in the cell-cell and cell-matrix adhesion of mammalian mast cells (MCs); however, it is unclear whether other adhesion molecule(s) perform important roles in the adhesion of MCs. In the present study, we show a novel Kit-independent adhesion mechanism of mouse cultured MCs mediated by Notch family members. On stromal cells transduced with each Notch ligand gene, Kit and its signaling become dispensable for the entire adhesion process of MCs from tethering to spreading. The Notch-mediated spreading of adherent MCs involves the activation of phosphatidylinositol 3-kinases and mitogen-activated protein kinases signaling, similar to Kit-mediated spreading. Despite the activation of the same signaling pathways, while Kit supports the adhesion and survival of MCs, Notch only supports adhesion. Thus, Notch family members are specialized adhesion molecules for MCs that effectively replace the adhesion function of Kit in order to support the interaction of MCs with the surrounding cellular microenvironments.

AB - Bacteria are of tremendous importance in the pharma- and bio-industry as producers of a broad range of economically interesting metabolites and proteins. Gram-positive bacteria are valuable hosts for the production of heterologous proteins for obvious reasons. Contrary to Gram-negative bacteria, Gram-positive bacteria release their secreted proteins immediately into the spent culture broth as they are not hindered by an outer membrane. Secretory protein production also avoids the formation of inclusion bodies, hence facilitating downstream processing. Eight protein secretion pathways have been described in Gram-positive bacteria, but solely the general secretion or Sec pathway and, to a lesser extent, the Twin-arginine pathway, are used for the recombinant protein production. This process is not always successful, but might be hampered by inefficient secretion, misfolding of the recombinant protein, its degradation by proteases and metabolic burden by the host hindering proper growth and diminishing product yield. In this review, the different protein export avenues will be briefly discussed, and the potential means to optimize protein secretion and yields for the Streptomyces lividans model presented. The proposed approaches are largely applicable for other Streptomyces host systems. PMID- 30299472 TI - Use of Soil and Litter Ants (Hymenoptera: Formicidae) as Biological Indicators of Soil Quality Under Different Land Uses in Southern Rwanda. AB - The use of soil and litter arthropods as biological indicators is a way to assess environmental changes, where ant species in particular may serve as important indicators of soil quality. This study aimed at relating the abundance of soil and litter ant species to soil parameters under different tree species, both native and exotic, and varieties of coffee and banana plantations. Variations were found in soil physicochemical parameters. A total of 30 species belonging to 14 genera, and four subfamilies, the Formicinae, Dorylinae, Myrmicinae, and Ponerinae were identified. Higher abundance was found in coffee plantations compared to banana plantations, exotic and native tree species. Species of Camponotus cinctellus and Odontomachus troglodytes occurred in all land uses which is a sign of tolerance to a wide range of soil properties. In addition, these species, together with Myrmicaria SP02, Phrynoponera gabonensis, Camponotus SP06, Myrmicaria opaciventris, Pheidole SP03, Tetramorium simillimum, Pheidole SP01, and Tetramorium laevithorax were not strongly correlated with soil physicochemical parameters. Species of Pheidole SP02 and Camponotus SP05 were restricted to specific soil physicochemical properties, while species of Tetramorium zonacaciae and Bothroponera talpa discriminated between native tree species, coffee plantations, soil organic carbon, sandy soil texture, and aggregate stability. We concluded that these ant species can differently indicate the soil quality depending on the land use. We recommended further studies in order to generalize these findings. PMID- 30299473 TI - Statin treatment decreases mitochondrial respiration but muscle coenzyme Q10 levels are unaltered: The LIFESTAT study. AB - Background: Myalgia is a common side effect to statin therapy, but the underlying mechanism is unknown. Statins may reduce Coenzyme Q10 (CoQ10) which is an essential electron carrier in the mitochondrial electron transport system, thereby impairing mitochondrial respiratory function potential leading to myalgia. Objectives: To investigate whether statin induced myalgia is coupled to reduced intramuscular CoQ10 concentration and impaired mitochondrial respiratory function. Methods: 64 men and women in simvastatin therapy were recruited. 25 who experienced myalgia were allocated to the myalgic group. The remaining 39 statin users had no symptoms of myalgia (non-sympt). 20 men and women with untreated high blood cholesterol levels were recruited as control group. Blood and muscle samples were obtained. Intramuscular CoQ10 concentration was measured, and mitochondrial respiratory function and reactive oxygen species (ROS) production were measured. Citrate Synthase (CS) activity was used as a biomarker for mitochondrial content in skeletal muscle. Results: Intramuscular CoQ10 concentration was comparable between groups. Mitochondrial complex II-linked respiration was reduced in the statin myalgic and statin non-symptomatic groups compared to control. When mitochondrial respiration was normalized to CS activity respiration rate was higher in the myalgic group compared to non-symptomatic and control group. Maximal ROS production was similar between groups. Discussion: Our results suggests that statin therapy impairs mitochondrial complex-II linked respiration, but the mitochondrial capacity for complex I+II linked respiration is intact. Myalgia is not coupled to reduced intramuscular CoQ10 levels. Intrinsic mitochondrial respiratory capacity is increased with statin induced myalgia, but not accompanied by increased ROS production. PMID- 30299474 TI - Friends or foes in the rhizosphere: traits of fluorescent Pseudomonas that hinder Azospirillum brasilense growth and root colonization. AB - Bacteria of the Azospirillum and Pseudomonas genera are ubiquitous members of the rhizosphere, where they stimulate plant growth. Given the outstanding capacity of pseudomonads to antagonize other microorganisms, we analyzed the interaction between these two bacterial groups to identify determinants of their compatibility. We could establish that, when in direct contact, certain Pseudomonas strains produce lethality on Azospirillum brasilense cells using an antibacterial type 6 secretion system. When analyzing the effect of Pseudomonas spp. diffusible metabolites on A. brasilense growth on King's B medium, we detected strong inhibitory effects, mostly mediated by siderophores. On Congo Red medium, both inhibitory and stimulatory effects were induced by unidentified compounds. Under this condition, Pseudomonas protegens CHA0 produced a Gac/Rsm regulated antibiotic which specifically inhibited A. brasilense Sp7 but not Sp245. This effect was not associated with the production of 2,4 diacetylphloroglucinol. The three identified antagonism determinants were also active in vivo, producing a reduction of viable cells of A. brasilense in the roots of wheat seedlings when co-inoculated with pseudomonads. These results are relevant to the understanding of social dynamics in the rhizosphere and might aid in the selection of strains for mixed inoculants. PMID- 30299475 TI - Evaluation of Escherichia coli pathotypes associated with irritable bowel syndrome. AB - Irritable bowel syndrome (IBS) affects 10%-20% of people. Increased numbers of Escherichia coli (E. coli) correlate with symptoms, and patients respond to antimicrobials targeting E. coli. We examined whether specific E. coli strains, phylogroups and pathotypes are associated with IBS. We evaluated 218 E. coli isolates from 33 IBS patients and 23 healthy controls. RAPD analysis revealed 89 E. coli strains (29 controls, 60 IBS), spanning the A, B1, B2 and D phylogroups. Strains were similarly enriched in virulence genes associated with extraintestinal pathogenic E. coli (ExPEC) and/or adherent-invasive E. coli (AIEC). Three strains harbored a diarrheagenic virulence gene (2 IBS, 1 control). Escherichia coli capable of invading epithelial cells or replicating in macrophages were detected in 53% of IBS and 50% controls, and 67% IBS and 45% controls respectively (P > 0.05). AIEC were identified in 33% of IBS patients vs 20% of controls (P = 0.35). Virulence genes ibeA, ColV and pduC were associated with intramacrophage persistence; ibeA and ColV were associated with epithelial invasion and AIEC pathotype (P < 0.05). IBS patients and controls are commonly colonized by E. coli that resemble ExPEC and display pathogen-like behavior in vitro, similar to CD-associated AIEC. The relationship of these resident pathosymbiont E. coli to IBS warrants further investigation. PMID- 30299476 TI - Quantitative proteomic analysis of xylose fermentation strain Pichia stipitis CBS 5776 to lignocellulosic inhibitors acetic acid, vanillin and 5 hydroxymethylfurfural. AB - To obtain a global insight into the dynamic protein expression pattern in Pichia stipitis during xylose fermentation in the presence of three representative inhibitors (acetic acid, vanillin and 5-hydroxymethylfurfural), proteins were extracted for quantitative proteomic analysis using 8-plex isobaric tag for relative and absolute quantitation (iTRAQ) on a liquid chromatography-mass/mass spectrometry instrument. Interestingly, aconitase (Aco1p) and NAD-isocitrate dehydrogenase (Idh1p) were upregulated during the middle exponential phase in the presence of the three inhibitors during tricarboxylic acid cycle. We speculated that yeast cells adaptively increased the expression of the tricarboxylic acid cycle proteins to compensate for low NADH derived from glycolysis in the presence of the three inhibitors. Proteins related to amino acid metabolism, aminoacyl tRNA synthesis and stress response were also significantly affected in the presence of the three inhibitors. Taken together, quantitative proteomic analysis is capable of monitoring P. stipitis xylose fermentation under inhibitor conditions and identifying physiological changes, such as stress response. PMID- 30299477 TI - eAssessment: development of an electronic version of the Objective Structured Assessment of Debriefing tool to streamline evaluation of video recorded debriefings. AB - Objective: The Objective Structured Assessment of Debriefing (OSAD) is an evidence-based, 8-item tool that uses a behaviorally anchored rating scale in paper-based form to evaluate the quality of debriefing in medical education. The objective of this project was twofold: 1) to create an easy-to-use electronic format of the OSAD (eOSAD) in order to streamline data entry; and 2) to pilot its use on videoed debriefings. Materials and Methods: The eOSAD was developed in collaboration with the LSU Health New Orleans Epidemiology Data Center using SurveyGizmo (Widgix Software, LLC, Boulder, CO, USA) software. The eOSAD was then piloted by 2 trained evaluators who rated 37 videos of faculty teams conducting pre-briefing and debriefing after a high-fidelity trauma simulation. Inter-rater reliability was assessed, and evaluators' qualitative feedback was obtained. Results: Inter-rater reliability was good [prebrief, intraclass correlation coefficient, ICC = 0.955 (95% CI, 0.912-0.977), P < .001; debrief, ICC = 0.853 (95% CI, 0.713-0.924), P < .001]. Qualitative feedback from evaluators found that the eOSAD was easy to complete, simple to read and add comments, and reliably stored data that were readily retrievable, enabling the smooth dissemination of information collected. Discussion: The eOSAD features a secure login, sharable internet access link for distant evaluators, and the immediate exporting of data into a secure database for future analysis. It provided convenience for end users, produced reliable assessments among independent evaluators, and eliminated multiple sources of possible data corruption. Conclusion: The eOSAD tool format advances the post debriefing evaluation of videoed inter-professional team training in high-fidelity simulation. PMID- 30299478 TI - A simple mathematical model to describe antibody-dependent enhancement in heterologous secondary infection in dengue. AB - We develop a mathematical model to describe the role of antibody-dependent enhancement (ADE) in heterologous secondary infections, assuming that antibodies specific to primary dengue virus (DENV) infection are being produced by immunological memory. The model has a virus-free equilibrium (VFE) and a unique virus-presence equilibrium (VPE). VFE is asymptotically stable when VPE is unstable; and unstable, otherwise. Additionally, there is an asymptotic attractor (not a fixed point) due to the fact that the model assumes unbounded increase in memory cells. In the analysis of the model, ADE must be accounted in the initial stage of infection (a window of time of few days), period of time elapsed from the heterologous infection until the immune system mounting an effective response against the secondary infection. We apply the results yielded by model to evaluate ADE phenomonon in heterologous DENV infection. We also associate the possible occurrence of severe dengue with huge viremia mediated by ADE phenomenon. PMID- 30299479 TI - Cross-sectional associations between body mass index and social-emotional wellbeing among differentially active children. AB - Background: This study assessed gender-specific associations between body mass index (BMI) and social-emotional wellbeing (SEW) among differentially active seven-year-old children. Methods: Data are from wave four of the UK Millennium Cohort Study, collected in 2007-08. Children wore an ActiGraph accelerometer for seven consecutive days and measures of stature and body mass were taken. BMI was calculated from stature and body mass (kg/m2). Parents/carers completed the strengths and difficulties questionnaire (SDQ). A total of 6011 children (3073 girls) had completed data. Mean minutes per day spent in moderate-to-vigorous intensity physical activity (MVPA) were calculated for each child. Gender specific MVPA quartile cut-off values categorized boys and girls separately into four graded groups representing the least (Q1) through to the most active (Q4) children. Adjusted linear regression analyses examined associations between BMI and SDQ scores. Gender-specific analyses were conducted separately for MVPA quartiles. Results: BMI was positively associated with peer problems for Q1 and Q2 boys and girls, conduct problems for Q2 and Q4 boys, emotional problems and prosocial behaviour for Q2 boys and total difficulty scores for Q1 girls and Q2 boys (P < 0.05). Conclusions: Our results revealed that BMI was positively associated with SEW difficulties among the low active children but not the high active children. Further research examining the concurrent effect of diet and MVPA on child weight status and SEW is needed. PMID- 30299480 TI - Characterization of the CYP11A1 Non-synonymous Variant p.E314K in Children Presenting with Adrenal Insufficiency. AB - Context: Cholesterol side-chain cleavage enzyme (P450scc), encoded by CYP11A1 catalyzes the first step of steroidogenesis. Complete P450scc deficiency leads to primary adrenal insufficiency (PAI) and 46,XY disordered sexual development. Partial impairment can cause variable adrenal and gonadal dysfunction. Objective: Our aim was to evaluate the effects of the CYP11A1 variant p.E314K, identified in patients with PAI, specifically on P450scc enzyme stability and function. Patients/Methods: We studied four males from two unrelated families presenting with PAI during childhood (3.6 to 9 years old). All patients were compound heterozygous for c.940G>A (p.E314K), a CYP11A1 non-synonymous variant likely to be pathogenic by some but not all in silico prediction models, and c.835delA (p.I79Yfs*10), a known pathogenic variant. HEK293T cells were transfected with wild-type (WT) and p.E314K mutant vectors, and a cycloheximide chase assay was performed to analyze protein stability. Pregnenolone production was assayed from cells expressing WT and p.E314K-F2 fusion proteins. Results: Two males experienced spontaneous puberty, but then developed evidence of primary gonadal failure at 14 and 18 years old. Two males had testicular adrenal rest tissue (TART), detected by ultrasound at ages 8.6 and 16 years. Compared to WT, mutant protein synthesis was reduced (P=0.0006) with increased protein turn over, and mutant P450scc half-life was decreased by approximately 50%. p.E314K mutant P450scc retained 60% of WT enzymatic activity (P=0.007). Conclusions: The CYP11A1 p.E314K variant impairs P450scc stability and is a possible cause of PAI during childhood. Pathogenic CYP11A1 variants potentially impact both adrenal and gonadal function and males may develop TART. PMID- 30299481 TI - How Clean Is the Linen at My Hospital? The Mucorales on Unclean Linen Discovery Study of Large United States Transplant and Cancer Centers. AB - Mucormycosis outbreaks have been linked to contaminated linen. We performed fungal cultures on freshly-laundered linens at 15 transplant and cancer hospitals. At 33% of hospitals, the linens were visibly unclean. At 20%, Mucorales were recovered from >10% of linens. Studies are needed to understand the clinical significance of our findings. PMID- 30299483 TI - Sex influences SAMHD1 activity and susceptibility to HIV-1 in primary human macrophages. AB - While it is known that host sex affects HIV-1 viremia and influences the severity of HIV-1 associated neurocognitive disease, a cellular or molecular basis for these findings remains elusive. Macrophages are major targets for HIV-1, contribute to viral propagation in vivo, and are instrumental in the pathogenesis of HAND. We explored whether sex affects HIV-1 infectivity of primary human macrophages and CD4+ T cells in vitro. We find that macrophages derived from female donors were less susceptible to HIV-1 infection than those derived from males. This sex-dependent difference in macrophage infectivity was independent of the requirement for CD4/CCR5-mediated virus entry and was not observed in CD4+ T cells. Investigations into the mechanism governing these sex-dependent differences revealed that the host restriction factor SAMHD1 exists in a hyperphosphorylated, less active state in male-derived macrophages. In addition, the major kinase responsible for SAMHD1 phosphorylation, CDK1, exhibited lower levels of expression in female-derived macrophages in all tested donor pairs. The sex-dependent differences in viral restriction imposed by SAMHD1 were abrogated upon its depletion. We conclude that SAMHD1 is an essential modulator of infectivity in a sex-dependent manner in macrophages, constituting a novel component of sex differences in innate immune control of HIV-1. PMID- 30299482 TI - Assessment of ovarian reserve after cystectomy versus 'one-step' laser vaporization in the treatment of ovarian endometrioma: a small randomized clinical trial. AB - STUDY QUESTION: Does CO2 laser vaporization offer better results in treating endometrioma in terms of ovarian reserve preservation compared to traditional cystectomy? SUMMARY ANSWER: Assessing both antral follicle count (AFC) and serum anti-Mullerian hormone (AMH) levels as measures of ovarian reserve, the results suggest that CO2 technology may be an alternative treatment for endometrioma, causing minimal damage to adjacent healthy ovarian tissue. WHAT IS KNOWN ALREADY: Excisional surgery has been questioned as an ideal surgical approach for endometriomas because it is associated with potential reduction of ovarian reserve. Recently, vaporization with CO2 laser in-line-of-sight, according to the 'three-step procedure', has been proposed as the best method to preserve ovarian function. However, no randomized controlled trials have been conducted to compare cystectomy and 'one-step' CO2 fiber laser vaporization (without GnRH agonist therapy) with respect to the ovarian reserve. STUDY DESIGN, SIZE, DURATION: A multicentre randomized clinical trial including 60 patients was performed between July 2017 and February 2018. Computerized randomization was conducted to allocate them in a proportion of 1:1 either to Group 1 (laparoscopic stripping: cystectomy) or Group 2 (CO2 laser vaporization). Patients in Group 1 underwent a standardized laparoscopic stripping technique; patients in Group 2 underwent drainage of the cyst content, biopsy and vaporization of the internal wall with a CO2 fiber laser. Patients underwent pelvic ultrasound examination to determine the AFC and blood sampling to determine AMH levels before surgery and at 1- and 3 month follow-up. PARTICIPANTS/MATERIALS, SETTING, METHODS: Patients undergoing surgery for symptomatic endometriomas (infertility and/or pelvic pain) larger than 3 cm were randomized in two groups according to the surgical technique. Patients aged >=40 years, or with deep infiltrating endometriosis/adenomyosis, or previously submitted to surgical procedures on the ovaries or to hysterectomy were excluded from the study. The primary endpoint was the comparison of intra group AFC changes before and after surgery (DeltaAFC) between the two groups (DeltaAFC Group 1 versus DeltaAFC Group 2). The secondary endpoint was the modification of serum AMH before and after surgery (DeltaAMH) between the two groups (DeltaAMH Group 1 versus DeltaAMH Group 2). MAIN RESULTS AND THE ROLE OF CHANCE: The AFC of the operated ovary was significantly increased in Group 2 (laser vaporization) compared with Group 1 (cystectomy) after surgery (Group 1: from 4.1 +/- 2.2 [mean +/- SD] at baseline to 6.3 +/- 3.5 at 3-month follow-up; 95% CI: 0.9-4; Group 2: from 3.6 +/- 1.9 at baseline to 8.6 +/- 4.2 at 3-month follow-up; 95% CI: 2.8-7.1; P = 0.016); serum AMH levels were significantly reduced at 3 months in Group 1 (from 2.6 +/- 1.4 ng/mL at baseline to 1.8 +/- 0.8 ng/mL at 3-month follow-up; 95% CI: -1.3 to -0.2; P = 0.012) compared with no reduction in Group 2 (from 2.3 +/- 1.1 ng/mL at baseline to 1.9 +/- 0.9 ng/mL at 3-month follow-up; 95% CI: -1 to -0.2; P = 0.09). LIMITATIONS, REASON FOR CAUTION: The key limitations of the trial were the low accuracy of AFC in estimating the ovarian reserve in ovaries with endometriomas, the limited study size and the relatively short follow-up, which do not allow us to draw definitive conclusions. WIDER IMPLICATIONS OF THE FINDINGS: The present study suggests that CO2 technology may treat endometrioma with minimal damage to the adjacent healthy ovarian tissue; however, this study should be considered as a preliminary clinical trial, intended to stimulate future larger trials to address this clinically relevant issue. STUDY FUNDING/COMPETING INTEREST(S): None. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov NCT03227640. TRIAL REGISTRATION DATE: 9 July 2017. DATE OF FIRST PATIENT'S ENROLLMENT: 24 July 2017. PMID- 30299484 TI - Steroid-Responsive Relapsing-Remitting Neutrophilic Encephalitis: A Case Report. AB - We report a case of a rapidly progressing, relapsing-remitting, steroid responsive granulocytic encephalitis without any signs of peripheral nervous system or other organ involvement. It apparently had an immune-mediated etiology that could not be attributed to any known disease entity. A 22-year-old man presented with rapidly progressive severe neurological symptoms caused by encephalitis. Examination of the cerebrospinal fluid as well as brain biopsy showed extensive accumulation of neutrophilic granulocytes with no hints of an infectious agent. Magnetic resonance imaging revealed multiple T2/FLAIR demarcated lesions. Subsequent to a steroid pulse therapy, the clinical symptoms and imaging abnormalities improved rapidly. Ten months later, the patient experienced a disease relapse, which again responded well to steroids. Forty months after the relapse, he is currently doing well on azathioprine. This case highlights that an immunosuppressive treatment should be considered in patients with extensive neutrophilic encephalitis when no infectious agent is detected. A new immune-mediated relapsing-remitting CNS disease entity might need to be considered. PMID- 30299486 TI - Global Health and the Infectious Diseases Physician-Scientist Workforce. PMID- 30299485 TI - Congress of Neurological Surgeons Systematic Review and Evidence-Based Guidelines on the Evaluation and Treatment of Patients With Thoracolumbar Spine Trauma: Novel Surgical Strategies. AB - BACKGROUND: Treatment of thoracolumbar burst fractures has traditionally involved spinal instrumentation with fusion performed with standard open surgical techniques. Novel surgical strategies, including instrumentation without fusion and percutaneous instrumentation alone, have been considered less invasive and more efficient treatments. OBJECTIVE: To review the current literature and determine the role of fusion in instrumented fixation, as well as the role of percutaneous instrumentation, in the treatment of patients with thoracolumbar burst fractures. METHODS: The task force members identified search terms/parameters and a medical librarian implemented the literature search, consistent with the literature search protocol (see Appendix I), using the National Library of Medicine PubMed database and the Cochrane Library for the period from January 1, 1946 to March 31, 2015. RESULTS: A total of 906 articles were identified and 38 were selected for full-text review. Of these articles, 12 articles met criteria for inclusion in this systematic review. CONCLUSION: There is grade A evidence for the omission of fusion in instrumented fixation for thoracolumbar burst fractures. There is grade B evidence that percutaneous instrumentation is as effective as open instrumentation for thoracolumbar burst fractures. QUESTION: Does the addition of arthrodesis to instrumented fixation improve outcomes in patients with thoracic and lumbar burst fractures? RECOMMENDATION: It is recommended that in the surgical treatment of patients with thoracolumbar burst fractures, surgeons should understand that the addition of arthrodesis to instrumented stabilization has not been shown to impact clinical or radiological outcomes, and adds to increased blood loss and operative time. Strength of Recommendation: Grade A. QUESTION: How does the use of minimally invasive techniques (including percutaneous instrumentation) affect outcomes in patients undergoing surgery for thoracic and lumbar fractures compared to conventional open techniques? RECOMMENDATION: Stabilization using both open and percutaneous pedicle screws may be considered in the treatment of thoracolumbar burst fractures as the evidence suggests equivalent clinical outcomes. Strength of Recommendation: Grade B The full version of the guideline can be reviewed at: https://www.cns.org/guideline-chapters/congress-neurological-surgeons-systematic review-evidence-based-guidelines/chapter_12. PMID- 30299487 TI - Pre-treatment cerebrospinal fluid bacterial load correlates with inflammatory response and predicts neurological events during tuberculous meningitis treatment. AB - Background: Mycobacterium tuberculosis (Mtb) bacillary load in the brain of those with tuberculous meningitis (TBM) may reflect the host ability to control the pathogen and determine disease severity and treatment outcomes. Methods: We measured pre-treatment cerebrospinal fluid (CSF) Mtb bacterial load by GeneXpert in 692 adults with TBM. We sought to understand the relationship between CSF bacterial load and inflammation, and their respective impact on disease severity and treatment outcomes. Results: Ten-fold higher Mtb load was associated with increased disease severity (Odds Ratio=1.59, p=0.001 for grade 1 versus grade 3), and increased CSF neutrophils (r=0.364, p<0.0001) and cytokine concentrations (r=0.438, p<0.0001). High Mtb load predicted new neurological events after starting treatment (Multinomial logistic regression, p=0.005), but not death. Death was previously associated with attenuated inflammatory response at the start of treatment, with reduced cytokine concentrations compared to survivors. In contrast, patients with high pre-treatment CSF bacterial loads, cytokines, and neutrophils were more likely to subsequently suffer neurological events. Conclusions: Pre-treatment GeneXpert-derived Mtb load may be a useful predictor of neurological complications occurring during TBM treatment. Therapeutic strategies aimed at reducing neurological complications and deaths from TBM may need reassessment, given the evidence for their divergent pathogenesis. PMID- 30299488 TI - Genome-Wide Association Study of Susceptibility Loci for Radiation-Induced Brain Injury. AB - Background: Radiation-induced brain injury is a nonnegligible issue in the management of cancer patients treated by partial or whole brain irradiation. In particular, temporal lobe injury (TLI), a deleterious late complication in nasopharyngeal carcinoma, greatly affects the long-term life quality of these patients. Although genome-wide association studies (GWASs) have successfully identified single nucleotide polymorphisms (SNPs) associated with radiation toxicity, genetic variants contributing to the radiation-induced brain injury have not yet been assessed. Methods: We recruited and performed follow-up for a prospective observational cohort, Genetic Architecture of Radiotherapy Toxicity and Prognosis, using magnetic resonance imaging for TLI diagnosis. We conducted genome-wide association analysis in 1082 patients and validated the top associations in two independent cohorts of 1119 and 741 patients, respectively. All statistical tests were two-sided. Results: We identified a promoter variant rs17111237 (A > G, minor allele frequency [MAF] = 0.14) in CEP128 associated with TLI risk (hazard ratio = 1.45, 95% confidence interval = 1.26 to 1.66, Pcombined=3.18 * 10-7) which is in moderate linkage disequilibrium (LD) with rs162171 (MAF = 0.18, R2 = 0.69), the top signal in CEP128 (hazard ratio = 1.46, 95% confidence interval = 1.29-1.66, Pcombined= 6.17 * 10-9). Combining the clinical variables with the top SNP, we divided the patients into different subgroups with varying risk with 5-year TLI-free rates ranging from 33.7% to 95.5%. CEP128, a key component of mother centriole, tightly interacts with multiple radiation-resistant genes and plays an important role in maintaining the functional cilia, which otherwise will lead to a malfunction of the neural network. We found that A > G alteration at rs17111237 impaired the promoter activity of CEP128 and knockdown of CEP128 decreased the clonogenic cell survival of U87 cells under radiation. Noteworthy, 12.7% (27/212) of the GWAS-based associated genes (P < .001) were enriched in the neurogenesis pathway. Conclusions: This three-stage study is the first GWAS of radiation-induced brain injury that implicates the genetic susceptibility gene CEP128 involved in TLI development and provides the novel insight into the underlying mechanisms of radiation-induced brain injury.

AB - Limited data exist on intravenous (IV) posaconazole dosing and the risk for hepatotoxicity it confers to children. In this study, we evaluated dosing and resulting trough levels in 10 pediatric patients on IV posaconazole. A therapeutic level in these patients was achieved 95% of the time. We found a median minimum effective dose of 6.55 mg/kg of body weight. No correlation was found between the duration or posaconazole trough level and an increased alanine transaminase level. PMID- 30299490 TI - The AP2/ERF transcription factor SmERF115 positively regulates the biosynthesis of phenolic acids in Salvia miltiorrhiza. AB - Phenolic acids are an important kind of active secondary metabolites produced in Chinese medicinal plant Salviamiltiorrhiza, with the increasing market demand. Here, a novel AP2/ERF transcription factor SmERF115 was isolated and functionally characterized. SmERF115 was most responsive to methyl jasmonate (MJ) treatment and was localized in the nucleus. The phenolic acid production was obviously increased in SmERF115-overexpressing hairy roots but with decreased tanshinones content. Oppositely, silence of SmERF115 reduced phenolic acid level but with improved tanshinones content. The expression of key biosynthetic gene SmRAS1 was up-regulated in SmERF115 overexpression lines but was downregulated in SmERF115 RNAi lines. Yeast one-hybrid (Y1H) and electrophoretic mobility shift assays (EMSAs) showed that SmERF115 directly binds to the promoter of SmRAS1, while Dual Luciferase (Dual-LUC) assays SmERF115 could activate expression of SmRAS1 in vivo. Furthermore, global transcriptomic analysis by RNA-seq revealed that expression of others genes such as PAL3, 4CL5, TAT3 and RAS4 were also increased in overexpressing line, implied that they were potentially involved in the SmERF115-mediated pathway. Therefore, SmERF115 is a positive regulator of salvianolic acid biosynthesis, which suggested that SmERF115 may be a potential target for further metabolic engineering of phenolic acid biosynthesis in S.miltiorrhiza.

AB - Background: Many African countries have introduced pneumococcal conjugate vaccine (PCV) into their routine immunization program to reduce the burden of morbidity and death that results from Streptococcus pneumoniae infection, yet immunogenicity and reactogenicity data from the region are limited for the 2 available PCV products. Methods: We conducted a randomized trial of 13-valent PCV (PCV13) in Bobo-Dioulasso, Burkina Faso. Infants received 3 doses of PCV at 6, 10, and 14 weeks of age or at 6 weeks, 14 weeks, and 9 months of age; toddlers received 2 doses 2 months apart or 1 dose beginning at 12 to 15 months of age; and children received 1 dose between 2 and 4 years of age. We measured each participant's serotype-specific serum immunoglobulin G concentration and opsonophagocytic activity before and after vaccination. For each age group, we compared immune responses between study arms and between the standard schedule in our study and the PCV13-licensing trials. Results: In total, 280 infants, 302 toddlers, and 81 children were assigned randomly and underwent vaccination; 268, 235, and 77 of them completed follow-up, respectively. PCV13 resulted in low reactogenicity in all the study arms. The vaccine elicited a strong primary immune response in infants after 2 or more doses and in children aged 1 to 4 years after 1 dose. Infants who received a booster dose exhibited a robust memory response. Immunogenicity was higher than or comparable to that observed in the PCV13-licensing trials for a majority of serotypes in all 3 age groups. Conclusions: PCV13 has a satisfactory immunogenicity and reactogenicity profile in this population. Our findings will help support decision making by countries regarding their infant and catch-up vaccination schedules. PMID- 30299492 TI - AL amyloidosis: advances in diagnostics and treatment. AB - AL amyloidosis (light chain; previously also called primary amyloidosis) is a systemic disease characterized by an amyloid deposition process affecting many organs, and which still has unsatisfactory survival of patients. The monoclonal light chains kappa (kappa) or lambda (lambda) or their fragments form the fibrils that deposit and accumulate in different tissues. Renal involvement is very frequent in AL amyloidosis and can lead to the development of nephrotic syndrome followed by renal failure in some cases. AL amyloidosis ultimately leads to destruction of tissues and progressive disease. With recent advances in the treatment, the importance of an early diagnosis of amyloidosis and correct assessment of its type is high. Histologic confirmation is based on Congo red detection of amyloid deposits in tissues but AL amyloidosis must also be distinguished from other systemic forms of amyloidoses with renal involvement, such as AA amyloidosis, amyloidosis with heavy chain deposition, fibrinogen Aalpha or ALECT2 (leukocyte chemotactic factor 2) deposition. Immunofluorescence (IF) plays a key role here. IF on formalin-fixed paraffin-embedded tissue after protease digestion, immunohistochemistry or laser microdissection with mass spectrometry should complete the diagnosis in unclear cases. Standard treatment with melphalan and prednisolone or with cyclophosphamide and dexamethasone has been replaced with newer drugs used for the treatment of multiple myeloma bortezomib, carfilzomib and ixazomib or thalidomide, lenalidomide and pomalidomide. High-dose melphalan supported by autologous stem cell transplantation remains the therapeutic option for patients with low-risk status. These new treatment options prolong survival from months to years and improve the prognosis in a majority of patients.

PMID- 30299493 TI - Chronic Traumatic Encephalopathy Within an Amyotrophic Lateral Sclerosis Brain Bank Cohort. AB - Chronic traumatic encephalopathy (CTE) is a progressive neurodegenerative disorder linked to repetitive head impacts and has been associated with amyotrophic lateral sclerosis (ALS), a fatal, degenerative neuromuscular disorder. The Department of Veterans Affairs Biorepository Brain Bank (VABBB) is a tissue repository that collects antemortem disease progression data and postmortem central nervous system tissue from veterans with ALS. We set out to determine the frequency of co-morbid ALS and CTE in the VABBB cohort and to characterize the clinical, genetic, and pathological distinctions between participants with ALS only and those with both ALS and CTE (ALS+CTE). Of 155 participants, 9 (5.8%) had neuropathologically confirmed ALS+CTE. Participants with ALS+CTE were more likely to have a history of traumatic brain injury (p < 0.001), served during the first Persian Gulf War (p < 0.05), and to have more severe tau pathology within the frontal cortex and spinal cord (p < 0.05). The most common exposures to head impacts included contact sports (n = 5) and military service (n = 2). Clinically, participants with ALS+CTE were more likely to have bulbar onset ALS (p = 0.006), behavioral changes (p = 0.002), and/or mood changes (p < 0.001). Overall, compared with ALS in isolation, comorbid ALS+CTE is associated with a history of TBI and has a distinct clinical and pathological presentation. PMID- 30299495 TI - Dynamic network approach for the modelling of genomic sub-complexes in multi segmented viruses. AB - Viruses with segmented genomes, including pathogens such as influenza virus, Rotavirus and Bluetongue virus (BTV), face the collective challenge of packaging their genetic material in terms of the correct number and types of segments. Here we develop a novel network approach to predict RNA-RNA interactions between different genomic segments. Experimental data on RNA complex formation in the multi-segmented BTV genome are used to establish proof-of-concept of this technique. In particular, we show that trans interactions between segments occur at multiple specific sites, termed segment assortment signals (SASs) that are dispersed across each segment. In order to validate the putative trans acting networks, we used various biochemical and molecular techniques which confirmed predictions of the RNA network approach. A combination of mutagenesis and reverse genetics systems revealed that the RNA-RNA interacting sites identified are indeed responsible for segment assortment and complex formation, which are essential criteria for genome packaging. This paves the way for their exploitation as novel types of drug target, either to inhibit assembly, or for designing defective interfering particles containing an incomplete set of genomic segments. PMID- 30299496 TI - Evaluating the Addition of CO2 to Black Light Traps for Sampling Culicoides (Diptera: Ceratopogonidae) in Alberta. AB - We examined the effect of augmenting black light trap with CO2 at two release rates for monitoring and surveillance of Culicoides at northern latitudes. Species composition was highly correlated among black light (BL) traps with no CO2 (BL0 traps) and traps augmented with 300 and 1000 ml/min CO2 (BL300 and BL1000 traps, respectively); however, traps augmented with CO2 captured one to three more rare species than BL0 traps and can detect rare species that might be missed if BL0 traps were used. Addition of CO2 increased the number of individuals captured from 1.4 to 38.5-fold for BL300 traps and from 1.5 to 153.5 fold for BL1000 traps. This advantage may be lost in areas with low abundance as might be expected at the limits of species. The daily probability of detecting a species was greater for traps augmented with CO2, but this can be compensated for by operating BL0 traps for sufficient time. The association between numbers captured by BL0 and BL300 and BL1000 traps also suggests that BL0 traps may provide useful measures of relative abundance for Culicoides sonorensis, Culicoides davisi, and Culicoides riethi, again providing the BL0 traps are left to operate for some period. Measurements of diel activity were influenced by trap type only for a single species and were primarily determined by solar radiation, temperature, and windspeed. Overall, the use of BL0 only traps for widescale surveys is supported, especially given their convenience. PMID- 30299497 TI - A 4-Year-Old Boy With an Unusual Bacterial Meningitis Infection. PMID- 30299498 TI - Association of thyroid status prior to transition to end-stage renal disease with early dialysis mortality. AB - Background: Advanced chronic kidney disease (CKD) patients, including those receiving dialysis, have a high prevalence of thyroid dysfunction. Although hypothyroidism is associated with higher death risk in end-stage renal disease (ESRD) patients, no studies have examined whether thyroid status in the pre-ESRD period impacts mortality after dialysis initiation. Methods: Among US veterans with CKD identified from the national Veterans Affairs database that transitioned to dialysis over the period from October 2007 to September 2011, we examined the association of pre-ESRD serum thyrotropin (TSH) levels averaged over the 1-year pre-dialysis ('prelude') period with all-cause mortality in the first year following dialysis initiation. Results: Among 15 335 patients in the 1-year prelude cohort, TSH levels >5.0 mIU/L were associated with higher mortality in expanded case-mix Cox models (reference: TSH 0.5-5.0 mIU/L): adjusted hazard ratio (aHR) [95% confidence interval (CI) 1.20 (1.07-1.33). Similar findings were observed for TSH >5.0 mIU/L and mortality in the 2- and 5-year cohorts: aHRs (95% CI) 1.11 (1.02-1.21) and 1.15 (1.07-1.24), respectively. Analyses of finer gradations of TSH in the 1-year prelude cohort demonstrated that incrementally higher levels >5.0 mIU/L were associated with increasingly higher mortality in expanded case-mix models (reference: TSH 0.5-3.0 mIU/L): aHRs (95% CI) 1.18 (1.04 1.33) and 1.28 (1.03-1.59) for TSH levels >5.0-10.0 mIU/L and >10.0 mIU/L, respectively. In the 2- and 5-year cohorts, mortality associations persisted most strongly for those with TSH >10.0 mIU/L, particularly after laboratory covariate adjustment. Conclusions: Among new ESRD patients, there is a dose-dependent relationship between higher pre-ESRD TSH levels >5.0 mIU/L and post-ESRD mortality. Further studies are needed to determine the impact of TSH reduction with thyroid hormone supplementation in this population. PMID- 30299499 TI - Relationship between fluorescence yield and photochemical yield under water stress with intermediate light. AB - The associated dynamics between fluorescence (Fs) yield and photochemical (P) yield in changing environment are essential for understanding the relationship between photosynthesis and fluorescence. It was reported that the ratio of Fs yield and P yield tends to be constant under high light intensity (Liu et al., 2017). However, under intermediate and low light, the relationship between these two yields and its response to environment conditions need to be further explored. In this study, leaf-scale measurements of fluorescence parameters by pulse-amplitude modulation (PAM) technology were conducted for summer maize (Zea mays L.) grown under intermediate light condition (the light intensity above canopy was kept at 700 MUmol m-2 s-1) in a climate chamber. Plants were treated as moderate water stressed (45% - 55% of the field capacity) and non-water stressed (> 80% of the field capacity). Results showed that, decreasing of P yield was accompanied with increasing of Fs yield and non-photochemical quenching (NPQ) yield in response to moderate water stress under intermediate and low light condition. Fs yield was negatively correlated with P yield (p < 0.01) under intermediate and low light condition when soil water in root zone was sufficient. However, under water stress, their correlation was negative at low light level (PAR < 450 MUmol m-2 s-1), but it turned to be positive under higher light (PAR >= 450 MUmol m-2 s-1 and PAR <= 700 MUmol m-2 s-1); Fs yield was negatively related with P yield when NPQ yield was low, however they were synergistically and positively associated with each other when excessive light dissipating was dominated by NPQ. In conclusion, the relationship between fluorescence yield and photochemical yield is affected by light intensity and water status. The positive linear relationship may not be directly used to estimate photosynthesis by fluorescence emission for plants under intermediate and low light condition.

PMID- 30299501 TI - Esrrb plays important roles in maintaining self-renewal of trophoblast stem cells (TSCs) and reprogramming somatic cells to induced TSCs. AB - Trophoblast stem cells (TSCs), which can be derived from the trophoectoderm of a blastocyst, have the ability to sustain self-renewal and differentiate into various placental trophoblast cell types. Meanwhile, essential insights into the molecular mechanisms controlling the placental development can be gained by using TSCs as the cell model. Esrrb is a transcription factor that has been shown to play pivotal roles in both embryonic stem cell (ESC) and TSC, but the precise mechanism whereby Esrrb regulates TSC-specific transcriptome during differentiation and reprogramming is still largely unknown. In the present study, we elucidate the function of Esrrb in self-renewal and differentiation of TSCs, as well as during the induced TSC (iTSC) reprogramming. We demonstrate that the precise level of Essrb is critical for stem state maintenance and further trophoblast differentiation of TSCs, as ectopically expressed Esrrb can partially block the rapid differentiation of TSCs in the absence of Fgf4. However, Esrrb depletion results in downregulation of certain key TSC-specific transcription factors, consequently causing a rapid differentiation of TSCs and these Esrrb deficient TSCs lose the ability of hemorrhagic lesion formation in vivo. This function of Esrrb is exerted by directly binding and activating a core set of TSC specific target genes including Cdx2, Eomes, Sox2, Fgfr4, and Bmp4. Furthermore, we show that Esrrb overexpression can facilitate the MEF-to-iTSC conversion. Moreover, Esrrb can substitute for Eomes to generate GEsTM-iTSCs. Thus, our findings provide a better understanding of the molecular mechanism of Esrrb in maintaining TSC self-renewal and during iTSC reprogramming. PMID- 30299502 TI - OpenProt: a more comprehensive guide to explore eukaryotic coding potential and proteomes. AB - Advances in proteomics and sequencing have highlighted many non-annotated open reading frames (ORFs) in eukaryotic genomes. Genome annotations, cornerstones of today's research, mostly rely on protein prior knowledge and on ab initio prediction algorithms. Such algorithms notably enforce an arbitrary criterion of one coding sequence (CDS) per transcript, leading to a substantial underestimation of the coding potential of eukaryotes. Here, we present OpenProt, the first database fully endorsing a polycistronic model of eukaryotic genomes to date. OpenProt contains all possible ORFs longer than 30 codons across 10 species, and cumulates supporting evidence such as protein conservation, translation and expression. OpenProt annotates all known proteins (RefProts), novel predicted isoforms (Isoforms) and novel predicted proteins from alternative ORFs (AltProts). It incorporates cutting-edge algorithms to evaluate protein orthology and re-interrogate publicly available ribosome profiling and mass spectrometry datasets, supporting the annotation of thousands of predicted ORFs. The constantly growing database currently cumulates evidence from 87 ribosome profiling and 114 mass spectrometry studies from several species, tissues and cell lines. All data is freely available and downloadable from a web platform (www.openprot.org) supporting a genome browser and advanced queries for each species. Thus, OpenProt enables a more comprehensive landscape of eukaryotic genomes' coding potential. PMID- 30299503 TI - Xylem functioning, dysfunction and repair: a physical perspective and implications for phloem transport. AB - Xylem and phloem are the two main conveyance systems in plants allowing exchanges of water and carbohydrates between roots and leaves. While each system has been studied in isolation for well over a century, the coupling and coordination between them remains the subject of inquiry and active research and frames the scope of the review here. Using a set of balance equations, hazards of bubble formation and their role in shaping xylem pressure and its corollary impact on phloem pressure and sugar transport are featured. The behavior of an isolated and freely floating air bubble within the xylem is first analyzed so as to introduce key principles such as the Helmholtz free energy and its links to embryonic bubble sizes. These principles are extended by considering bubbles filled with water vapor and air arising from air seeding. Using this framework, key results about stability and hazards of bubbles in contact with xylem walls are discussed. A chemical equilibrium between phloem and xylem systems is then introduced to link xylem and osmotic pressures. The consequences of such a link for sugar concentration needed to sustain efficient phloem transport by osmosis in the loading zone is presented. Catastrophic cases where phloem dysfunction occurs are analyzed in terms of xylem function and its vulnerability to cavitation. A link between operating pressures in the soil system bounded by field capacity and wilting points and maintenance of phloem functioning are discussed as conjectures to be tested in the future. PMID- 30299505 TI - A standardization method to disentangle environmental information from axial trends of xylem anatomical traits. AB - Anatomical traits such as xylem conduit diameter and vessel connectivity are fundamental characteristics of the hydraulic architecture of vascular plants. Stem xylem conduits are narrow at the stem apex, and this confers resistance to embolisms that might otherwise be induced by large, negative water potentials at the top of tall trees. Below the apex, conduits progressively widen and this characteristic minimizes effects of path length on total hydraulic resistance. While interconnections among xylem vessels have been noted for decades, their role(s) are not fully clarified. For example, we do not know if they allow water to bypass embolized vessels, or increase the risk of spread of embolisms, or how their arrangement varies within a tree. Here we demonstrate the benefit of removing the independent effect of stem length on assessment of effects of external (e.g., climatic) factors on such xylem traits. We measured the hydraulic diameter (Dh) and vessel conductivity index (VCI) along the stem of 21 shrubs/trees of similar height (1.19 < H < 5.45 m) belonging to seven Acacia species, across a wide aridity gradient in Australia. All trees showed similar scaling exponents of Dh (b = 0.33) and VCI (b = 0.53) vs axial distance from the apex (L), thus conforming with general patterns in woody plants. After de trending for L, neither Dh (P = 0.21) nor VCI (P = 0.109) differed across the aridity gradient. We found that across a wide gradient of aridity, climate had no effect on xylem anatomy of Acacia spp, which was instead dictated by axial distances from stem apices. We argue that the use of standardization procedures to filter out intrinsic patterns of vascular traits is an essential step in assessing climate-driven modifications of xylem architecture.

AB - Objective: Findings regarding small nerve fiber damage in complex regional pain syndrome type I (CRPS-I) are not uniform, and studies have not included a matched healthy control group. The aim was to assess intraepidermal nerve fiber density (IENFD) in relation to thermal sensitivity of the same skin areas in CRPS-I patients and a gender- and age-matched healthy control group. Methods: IENFD was investigated in skin biopsies from the CRPS-affected and contralateral limbs of eight CRPS-I patients and from an equivalent site in eight gender- and age matched healthy controls (HCs). Thermal thresholds (cold/warm detection, cold- and heat-pain detection) were assessed on the affected limb, the matching contralateral limb, and on the equivalent limbs of HCs, and participants rated the intensity of cold/heat and pain to static thermal stimuli (5 degrees C and 40 degrees C). Results: IENFD was significantly lower in both the affected and contralateral limbs of CRPS-I patients than HCs, but IENFD did not differ between the affected and contralateral limbs of patients. The heat pain threshold was lower in the affected CRPS-I limb than in HCs, but all other thermal thresholds were similar in both groups. CRPS-I patients rated the cold stimulus as colder and more painful in the affected limb, and the warm stimulus as hotter, bilaterally, than the HCs. Conclusions: CRPS-I may be associated with bilateral small fiber damage, and perhaps small fiber neuropathy and bilateral disturbances in thermo-sensory perception. These disturbances could stem from a systemic response to injury or might increase the risk of developing CRPS-I after physical trauma. PMID- 30299504 TI - Genetics of Human Longevity From Incomplete Data: New Findings From the Long Life Family Study. AB - The special design of the Long Life Family Study provides a unique opportunity to investigate the genetics of human longevity by analyzing data on exceptional lifespans in families. In this article, we performed two series of genome wide association studies of human longevity which differed with respect to whether missing lifespan data were predicted or not predicted. We showed that the use of predicted lifespan is most beneficial when the follow-up period is relatively short. In addition to detection of strong associations of SNPs in APOE, TOMM40, NECTIN2, and APOC1 genes with longevity, we also detected a strong new association with longevity of rs1927465, located between the CYP26A1 and MYOF genes on chromosome 10. The association was confirmed using data from the Health and Retirement Study. We discuss the biological relevance of the detected SNPs to human longevity. PMID- 30299509 TI - Influence of dietary zinc concentration and supplemental zinc source on nutrient digestibility, zinc absorption, and retention in sheep. AB - The objective of this study was to assess whether supplemental Zn source or concentration would affect ruminant Zn retention and nutrient digestibility. Thirty-six weaned crossbred Polypay wethers, were sorted by BW to 3 periods and stagger started on a common diet (22 mg Zn/kg DM) for a 52-d depletion period. Day 52 BW was used to assign Zn treatments (3 lambs/treatment/period): no supplemental Zn (CON), or supplemental Zn (40 mg Zn/d) from Zn sulfate (ING; Zinc Nacional, Monterrey, SA, Mexico), Zn methionine (ORG; Zinpro 120; Zinpro, Eden Prairie, MN), or Zn hydroxychloride (HYD; IntelliBond Z; Micronutrients USA LLC, Indianapolis, IN). On day 53 (day 1 of Zn treatments), lambs were moved to metabolism crates for 10 d of adaptation and 5 d of total fecal and urine collection. Blood for plasma Zn analysis was collected on day 52 and day 68. Data were analyzed as a randomized complete design with fixed effects of treatment, period and the interaction, which was significant (P >= 0.19) for day 68 plasma Zn but was removed for all other variables. Contrast statements were used to separate treatment means: CON vs. ZINC (ING, ORG, HYD), ING vs. HYD, and ORG vs. HYD. Day 52 plasma Zn concentrations were similar when CON was compared with ZINC (P = 0.84), and when ING and ORG were compared with HYD (P >= 0.19). Dry matter and neutral detergent fiber digestibility were lesser in ORG compared with HYD (P = 0.05) and organic matter and acid detergent fiber digestibility tended (P <= 0.08) to be lesser in ORG compared with HYD. Intake and fecal excretion of Zn was lesser, while apparent absorption of Zn was greater, in CON compared with ZINC (P <= 0.001). Zinc retained as a percent of Zn intake was greater in CON compared with ZINC (P = 0.001). Zinc retained (mg/d) was similar in CON compared with ZINC (P = 0.58) and when ING or ORG were compared with HYD (P >= 0.83). There was a treatment * period interaction for day 68 plasma Zn where treatments did not differ for periods 1 and 3 but ORG lambs had increased plasma Zn in period 2 compared with other treatments (P = 0.02). Lambs receiving no supplemental Zn had increased apparent absorption, suggesting Zn absorption may be upregulated in these lambs. Similarities in Zn retention across treatments suggests Zn requirements of these lambs were met regardless of supplementation concentration or source. Nutrient digestibility was improved in HYD lambs compared with ORG, and further work is needed to clarify the influence of supplemental Zn source on nutrient digestion. PMID- 30299510 TI - Heparin-binding protein release is strongly induced by Leptospira spp. and is a candidate for an early diagnostic marker of human leptospirosis. AB - Background: Leptospirosis is one of the most widespread zoonosis worldwide, caused by spirochetes of the genus Leptospira. Efficient leptospirosis early diagnostic methods are still lacking and acute disease presents with non-specific symptomatology, being often misdiagnosed. The leptospires pathogenic processes and virulence mechanisms remain virtually unknown. In severe infections, hemostatic impairment is frequently observed, and pathophysiological complications often develop when the host response is modulated by the pathogen. The neutrophil heparin-binding protein (HBP) is an inflammatory mediator and potent inducer of vascular leakage. Results: In this study, we found that leptospires and their secreted products induce the release of HBP from stimulated neutrophils through a controlled degranulation mechanism. We acknowledged two leptospiral proteins as able to induce HBP degranulation. These findings have clinical implications, as high levels of HBP were detected in serum of leptospirosis patients, especially at the early phase of the disease. Conclusion: In conclusion, we describe a new mechanism by which the leptospirosis pathophysiological complications may arise, such as vascular leakage and oedema formation. We also propose HBP as a new early screening biomarker for human leptospirosis. PMID- 30299508 TI - Targeting Exercise Interventions to Patients With Cancer in Need: An Individual Patient Data Meta-Analysis. AB - Background: Exercise effects in cancer patients often appear modest, possibly because interventions rarely target patients most in need. This study investigated the moderator effects of baseline values on the exercise outcomes of fatigue, aerobic fitness, muscle strength, quality of life (QoL), and self reported physical function (PF) in cancer patients during and post-treatment. Methods: Individual patient data from 34 randomized exercise trials (n = 4519) were pooled. Linear mixed-effect models were used to study moderator effects of baseline values on exercise intervention outcomes and to determine whether these moderator effects differed by intervention timing (during vs post-treatment). All statistical tests were two-sided. Results: Moderator effects of baseline fatigue and PF were consistent across intervention timing, with greater effects in patients with worse fatigue (Pinteraction = .05) and worse PF (Pinteraction = .003). Moderator effects of baseline aerobic fitness, muscle strength, and QoL differed by intervention timing. During treatment, effects on aerobic fitness were greater for patients with better baseline aerobic fitness (Pinteraction = .002). Post-treatment, effects on upper (Pinteraction < .001) and lower (Pinteraction = .01) body muscle strength and QoL (Pinteraction < .001) were greater in patients with worse baseline values. Conclusion: Although exercise should be encouraged for most cancer patients during and post-treatments, targeting specific subgroups may be especially beneficial and cost effective. For fatigue and PF, interventions during and post-treatment should target patients with high fatigue and low PF. During treatment, patients experience benefit for muscle strength and QoL regardless of baseline values; however, only patients with low baseline values benefit post-treatment. For aerobic fitness, patients with low baseline values do not appear to benefit from exercise during treatment. PMID- 30299511 TI - Seroprevalence, risk factors and spatial distribution of West Nile virus in Jordan. AB - Background: This is the first countrywide study of the seroprevalence, risk factors and spatial distribution of West Nile virus (WNV) in Jordan. Methods: A cross-sectional sample of 801 participants was administered a comprehensive questionnaire survey and tested for WNV immunoglobulin G antibodies. Results: The point seroprevalence rate for WNV infection was 8.61% (95% confidence interval 6.8 to 10.8). Multivariate regression analysis demonstrated that sex, age, climate, income and drinking water source were significantly associated with seropositivity (p<=0.05). Males had 1.73 greater odds of infection compared with females. Compared with 15 to 29-year-olds, adults 30-49 y old and adults >=50 y old had 2.0 and 3.1 greater odds of infection, respectively. Individuals living in the Jordan Valley and Badia had 22.2 and 7.2 times greater odds of infection, respectively, compared with individuals living in the highlands. Households with an income of 3); foetal asphyxia; low birth-weight (< 2,500 g); and hypoxic ischaemic encephalopathy. CONCLUSION: The prevalence of cerebral palsy in Henan province was 2.37 per 1,000 live births. Parents and clinicians should be aware of the risk factors for cerebral palsy.

Out of 1 336 patients a total of 34 patients (2,5 %) were transfused without any adverse events. Our demography is predominantly male and the most common mechanism of injury is trauma. Amongst the most common interventions were endotracheal intubation, thoracostomy and CPR. Preliminary analysis showed an increase in median systolic blood pressure and decrease in median heart rate after prehospital blood transfusion. Half of the patients that received CPR had return of spontaneous circulation (ROSC). We conclude that prehospital blood transfusion in a Swedish physician-staffed helicopter emergency medical service is feasible and safe. PMID- 30299529 TI - ? PMID- 30299528 TI - [Postural orthostatic tachycardia syndrome]. AB - Postural orthostatic tachycardia syndrome (POTS) is a condition where the patient experiences tachycardia (a rise in heart rate of at least 30 beats per minute, 40 in people between the ages of 12 and 19) upon assuming the upright position, in the absence of orthostatic hypotension (a fall in systolic blood pressure of more than 20 mmHg). The majority of patients are young women. Symptoms are experienced frequently during standing, and include dizziness, fatigue, palpitations, tremulousness, blurred vision and sometimes syncope - although presyncope is more common. The diagnosis requires that symptoms have been present for at least six months and lack another medical explanation. The pathophysiology is believed to be multifactorial; peripheral sympathetic denervation, excessive sympathetic drive, hypovolemia and deconditioning have been reported in POTS. Patient education is fundamental in the management of POTS, including information regarding symptoms and exacerbating factors as well as methods for increasing arterial pressure. Exercise is believed to be effective. Several drugs can be used to relieve symptoms, although none of them are licensed for the treatment of POTS. We describe a case that illustrates that POTS can be debilitating, which requires awareness of the condition among clinicians.

AB - A hiatal hernia is a partial or total dislocation of the stomach, sometimes together with other intraabdominal organs, through the diaphragmatic esophageal hiatus into the thoracic cavity. The condition is common and often asymptomatic. Old age and obesity are risk factors for developing hiatal hernia. Small hernias might induce gastroesophageal reflux, which usually is satisfactorily treated pharmacologically. Larger hiatal hernias are more often associated with obstructive symptoms including dysphagia, vomiting or discomfort/pain due to compression of adjacent organs/tissues. In severe cases, large hiatal hernias may become incarcerated with ischemia in herniated tissues and need of acute surgical intervention. The risk of complications in association with operation for large hiatal hernias is high, particularly in acute surgery and in elderly patients with co-morbidities.

All patients diagnosed between January 1st 2016 and September 14th 2017 in the county of Vasterbotten, Sweden were included (n=307). The proportion of patients with CRC who had their colon investigated before diagnosis was 7% (n=22). The median time from the index examination to the date of diagnosis of CRC was 1013 days (IQR 639 days). In addition, 16% of the patients had a positive FIT test (F-Hb) and 23% had anemia that was known more than three months prior to diagnosis. A long duration of anemia before diagnosis was significantly more common in men than in women (31% vs 16%; p=0.003). We conclude that the incidence of "missed" CRC are low but may be improved by a thorough adherence to colonoscopy guidelines. We found that a positive iFOBT and anemia often were detected more than three months prior to diagnosis. PMID- 30299532 TI - ? PMID- 30299533 TI - Prevalence of second canal in the mesiobuccal root of permanent maxillary molars from a Turkish subpopulation: a cone-beam computed tomography study. AB - BACKGROUND: Permanent maxillary molar teeth have the most complex root and canal systems. This study aimed to determine the frequency and the localization of secondary mesiobuccal canal (MB2) in the mesiobuccal roots of permanent maxillary molars in a Turkish subpopulation using cone beam computed tomography (CBCT) and compare them by different age groups and gender. MATERIALS AND METHODS: In this retrospective study, a total of 800 maxillary molar teeth in 200 subjects were investigated. The distances between canals were calculated from the center point of the MB2 canal (PMB2) to the center point of the mesiobuccal canal (PMB1) and the center point of the palatal canal (PP). RESULTS: The incidence of MB2 canals was found to be 33.5% (23.2% in females, 43.6% in males) in 200 subjects. A significant difference was found between age groups and genders in terms of the frequency of MB2 (p<0.05). The distances between PMB1-PMB2 were 2.95 +/- 0.58 mm, 3.08 +/- 0.67 mm for 1MM and 2MM, respectively. For 1MM and 2MM, the averages of PMB2-PP distances were 5.81 +/- 1.09 mm and 5.55 +/- 1.09 mm, respectively. The contralateral formation of the MB2 canals was 90.5% (16, 26) in the first molars and 93.9% in the second molars (17, 27). The contingency rate in the first quadrant was 86.0% (16, 17) and 83.5% (26, 27) in the second quadrant. CONCLUSIONS: It is important for the clinician to know the high probability of finding the MB2 canal in the maxillary first and second molars. CBCT imaging can facilitate the clinician to detect complex and variable root canal anatomy. PMID- 30299534 TI - Accessory head of the flexor pollicis longus muscle: anatomical study and clinical significance. AB - BACKGROUND: The accessory head of the flexor pollicis longus (AHFPL) has an oblique trajectory from medial to lateral aspect of the forearm below the flexor digitorum superficialis muscle and then joins the flexor pollicis longus muscle. When the anterior interosseous nerve (AIN) courses underneath the muscle belly of the AHFPL an entrapment neuropathy may occur, known as anterior interosseous nerve syndrome (AINS). MATERIALS AND METHODS: This descriptive cross-sectional study evaluated 106 fresh upper extremities. When the AHFPL was present, its fascicle was traced up to evaluate the origin site. The morphometric variables were measured using a digital micrometer (Mitutoyo, Japan). The relationship between the AHFLP and the AIN was evaluated. RESULTS: The AHFPL was found in 34 (32.1%) of the 106 forearms. The AHFPL arose from the flexor digitorum superficialis muscle in 16 forearms (47.1%), the medial epicondyle of the humerus in ten forearms (29.4%) and the coronoid process of ulna in eight forearms (23.5%). The average total length of the AHFPL was 94.11 +/- 10.33 mm. The AIN was located lateral to the AHFPL in three forearms (8.8%), posterolateral in seven forearms (20.6%) and posterior in 24 forearms (70.6%). CONCLUSIONS: This study performed in a South American population sample revealed a prevalence of the AHFPL in a lower range compared to previous studies in North Americans and Asians. The AIN coursed more frequently underneath the muscle belly of AHFPL. This finding has clinical significance in the onset of the AINS and the subsequent surgical procedure for the AIN decompression. PMID- 30299535 TI - The play skills of children with high-functioning autism spectrum disorder in peer-to-peer interactions with their classmates: A multiple case study design. AB - BACKGROUND/AIM: Children with ASD are known to have lower play skills than their typically developing peers. However, the play skills of children with ASD are rarely investigated using observational measures in the context of their everyday peer-to-peer play interactions. To explore the play skills of children with ASD and their aged matched classmates during a peer-to-peer play interaction. METHODS: Using convenience sampling, four children with ASD (5-11 years) attending mainstream schools were recruited for this multiple case design study. Each child with ASD was paired with one of their aged matched typically developing classmates. Children's play skills were measured using the Test of Playfulness (ToP). Additional case data were collected through teacher-reported social skills and behaviours. Rasch analysis was utilised to convert raw ToP scores into an interval level overall score for each child. Children's individual ToP item scores, social skills and behaviours are presented by case. RESULTS: The two children with ASD who had the highest ToP scores, also had the highest teacher-reported social skills. All children with ASD had greatest difficulty on ToP items reflecting suspension of reality and framing. Two children with ASD had higher ToP scores than their classmate. In these two cases, the classmates had similar play skills of children with ASD. CONCLUSION: The play skills of children with ASD varied by case. Across the cases, teacher-reported social skills, classmate age and existence of friendship between children were all factors observed to influence play. These findings require replication and investigation in larger scale studies. PMID- 30299536 TI - Symbiotic dinitrogen fixation is seasonal and strongly regulated in water-limited environments. AB - Plants, especially perennials, growing in drylands and seasonally dry ecosystems are uniquely adapted to dry conditions. Legume shrubs and trees, capable of symbiotic dinitrogen (N2 ) fixation, often dominate in drylands. However, the strategies that allow symbiotic fixation in these ecosystems, and their influence on the nitrogen cycle, are largely unresolved. We evaluated the climatic, biogeochemical and ontogenetic factors influencing nitrogen fixation in an abundant Mediterranean legume shrub, Calicotome villosa. We measured nodulation, fixation rate, nitrogen allocation and soil biogeochemistry in three field sites over a full year. A controlled experiment evaluated differences in plant regulation of fixation as a function of soil nutrient availability and seedling and adult developmental stages. We found a strong seasonal pattern, shifting between high fixation rates during the rainy season at flowering and seed-set times to almost none in the rainless season. Under controlled conditions, plants downregulated fixation in response to soil nitrogen availability, but this response was stronger in seedlings than in adult shrubs. Finally, we did not find elevated soil nitrogen under N2 -fixing shrubs. We conclude that seasonal nitrogen fixation, regulation of fixation, and nitrogen conservation are key adaptations influencing the dominance of dryland legumes in the community, with broader consequences on the ecosystem nitrogen cycle. PMID- 30299537 TI - The first case of severe acute hemolytic transfusion reaction caused by anti-Sc2. AB - BACKGROUND: Alloantibodies to the low-frequency antigen Scianna-2 (Sc2) have been implicated in cases of hemolytic disease of the fetus and newborn but never in hemolytic transfusion reactions (HTRs); thus, the clinical significance of anti Sc2 has yet to be fully addressed. STUDY DESIGN AND METHODS: A 26-year-old woman with thalassemia presented rigors, fever, nausea, abdominal pain, and hemolytic biochemistry after exposure to 75 mL of plasma-reduced red blood cells (RBCs). The RBC unit was issued by electronic crossmatch but was 3+ incompatible on recrossmatch by gel indirect antiglobulin test (IAT). The patient had anti-Sc2 previously identified, but considered to be clinically insignificant. The transfusion history was reviewed and a monocyte monolayer assay (MMA) was performed. RESULTS: The patient was investigated for a RBC reaction 9 years prior, when she developed symptoms of HTR. The RBC unit was crossmatched by immediate spin due to consistent screen negativity. Full crossmatch found the RBC 1+ incompatible by gel IAT with both pre/post samples, while direct antiglobulin test was negative (pre) and 1+ immunoglobulin G positive (post). The antibody remained unidentified and she was committed to gel IAT crossmatch. Two-years later, the specificity to Sc2 was deduced when one RBC unit was found 3+ incompatible. Finally, the transfusion reaction reported herein occurred when she received by happenstance RBCs from the same donor who was associated with the remote reaction 9 years earlier. MMA yielded highly positive phagocytic indices only for Sc2+ RBCs, including the donor's RBCs that triggered the severe HTR. CONCLUSION: This is the first case of HTR caused by anti-Sc2 confirmed by clinical findings and MMA.

AB - BACKGROUND: The aim of this study was to determine and compare the added prognostic value of screening tools, geriatric assessment (GA) components, and GA summaries to clinical information for overall survival (OS) in older patients with cancer. METHODS: A screening and a 10-item GA were systematically performed in patients >=70 years old with cancer. Cox regression analyses were conducted to evaluate the added prognostic value for OS of screening tools, GA, and GA summaries to clinical information (age, stage, and tumor type) in 2 cohorts (A and B). Cox models were compared on the basis of the Akaike information criterion and the concordance probability estimate. The 2 cohorts for the analyses were similar but independent. RESULTS: A complete case analysis was available for 763 patients (median age, 76 years) in cohort A and for 402 patients (median age, 77 years) in cohort B. In both cohorts, most individual GA components were independent prognostic factors for OS. Nutritional status (assessed with the Mini Nutritional Assessment Short Form) and functional status (assessed with the Instrumental Activities of Daily Living) consistently displayed a strong capacity to predict OS. Less consistent results were found for screening tools. GA summaries performed the best in comparison with the screening tools and the individual GA components. CONCLUSIONS: Most individual GA components, especially nutritional status and functional status, are prognostic factors for OS in older patients with cancer. GA summaries provide more prognostic information than individual GA components but only moderately improve the prognostic baseline model with clinical information. PMID- 30299541 TI - Leaf litter decay rates differ between mycorrhizal groups in temperate, but not tropical, forests. AB - Whereas the primary controls on litter decomposition are well established, we lack a framework for predicting interspecific differences in litter decay within and across ecosystems. Given previous research linking tree mycorrhizal association with carbon and nutrient dynamics, we hypothesized that the two dominant mycorrhizal groups in forests - arbuscular mycorrhizal (AM) and ectomycorrhizal (ECM) fungi - differ in litter decomposition rates. We compiled leaf litter chemistry and decay data for AM- and ECM-associating angiosperms and gymnosperms (> 200 species) from temperate and tropical/subtropical, and investigated relationships among decay rates, mycorrhizal association, phylogeny and climate. In temperate forests, AM litters decayed faster than ECM litters, with litter nitrogen and phylogeny best explaining variation in litter decay. In sub/tropical forests, we found no significant difference in litter decay rate between mycorrhizal groups, and variation in decay rates was best explained by litter phosphorus. Our results suggest that knowledge of tree mycorrhizal association may improve predictions of species effects on ecosystem processes, particularly in temperate forests where AM and ECM species commonly co-occur, providing a predictive framework for linking litter quality, organic matter dynamics and nutrient acquisition in forests. PMID- 30299542 TI - A phase 1, open-label, dose escalation study of intravenous paricalcitol in combination with gemcitabine in patients with advanced malignancies. AB - BACKGROUND: Calcitriol, the active analogue of vitamin D, is antiproliferative and enhances the cytotoxicity of several anticancer agents, including gemcitabine. The vitamin D receptor (VDR) is expressed in the tumor stroma and treatment with VDR ligands results in stromal remodeling and increased intratumoral gemcitabine delivery. Furthermore, calcitriol can decrease the activity of the gemcitabine deactivating enzyme cytidine deaminase (CDD). Because hypercalcemia has been the most worrisome calcitriol-related adverse event, the less hypercalcemic agent paricalcitol may be preferred for further investigation. METHODS: The authors undertook a phase 1 study of gemcitabine in combination with escalating doses of paricalcitol administered weekly intravenously in patients with advanced cancers. A standard 3+3 dose escalation schema was used. Pharmacokinetic assessment of gemcitabine and its metabolite 2',2' difluorodeoxyuridine (dFdU) was performed. Pharmacodynamic assessment of paricalcitol was performed by measurement of CDD activity in peripheral blood mononuclear cells. RESULTS: A total of 44 patients were enrolled. Somnolence was the main dose-limiting toxicity. The highest dose of paricalcitol administered was 10.5 ug/kg. Hypercalcemia was infrequent and mild in severity. Paricalcitol did not appear to affect the pharmacokinetics of gemcitabine and dFdU. Evaluation of CDD activity was available for 9 patients; no clear trend for CDD activity after treatment with paricalcitol was established. The overall response rate was 4%; the rate of disease control was 67% in patients who were pretreated with gemcitabine. Progression-free and overall survival were 3.4 months and 6.5 months, respectively. CONCLUSIONS: Paricalcitol can be administered safely in doses up to 7 ug/kg weekly with fixed dose rate gemcitabine without dose-limiting hypercalcemia. To the best of the authors' knowledge, the maximum tolerated dose has not been formally established to date. Preliminary clinical activity deserves further exploration. PMID- 30299543 TI - Repeated domestication of melon (Cucumis melo) in Africa and Asia and a new close relative from India. AB - PREMISE OF THE STUDY: The domestication history of melon is still unclear. An African or Asian origin has been suggested, but its closest wild relative was recently revealed to be an Australian species. The complicated taxonomic history of melon has resulted in additional confusion, with a high number of misidentified germplasm collections currently used by breeders and in genomics research. METHODS: Using seven DNA regions sequenced for 90% of the genus and the major cultivar groups, we sort out described names and infer evolutionary origins and domestication centers. KEY RESULTS: We found that modern melon cultivars go back to two lineages, which diverged ca. 2 million years ago. One is restricted to Asia (Cucumis melo subsp. melo), and the second, here described as C. melo subsp. meloides, is restricted to Africa. The Asian lineage has given rise to the widely commercialized cultivar groups and their market types, while the African lineage gave rise to cultivars still grown in the Sudanian region. We show that C. trigonus, an overlooked perennial and drought-tolerant species from India is among the closest living relatives of C. melo. CONCLUSIONS: Melon was domesticated at least twice: in Africa and Asia. The African lineage and the Indian C. trigonus are exciting new resources for breeding of melons tolerant to climate change. PMID- 30299544 TI - Retrograde signalling as an informant of circadian timing. AB - The circadian system comprises interlocking transcriptional-translational feedback loops that regulate gene expression and consequently modulate plant development and physiology. In order to maximize utility, the circadian system is entrained by changes in temperature and light, allowing endogenous rhythms to be synchronized with both daily and seasonal environmental change. Although a great deal of environmental information is decoded by a suite of photoreceptors, it is also becoming apparent that changes in cellular metabolism also contribute to circadian timing, through either the stimulation of metabolic pathways or the accumulation of metabolic intermediates as a consequence of environmental stress. As the source of many of these metabolic byproducts, mitochondria and chloroplasts have begun to be viewed as environmental sensors, and rapid advancement of this field is revealing the complex web of signalling pathways initiated by organelle perturbation. This review highlights recent advances in our understanding of how this metabolic regulation influences circadian timing. PMID- 30299545 TI - Do tall tree species have higher relative stiffness than shorter species? AB - PREMISE OF THE STUDY: In 1757 Leonhard Euler demonstrated that to avoid bending tall columns needed to be stiffer but not stronger than shorter columns of equal diameter and material density. Many researchers have concluded that trees have a fixed stiffness to basic density ratio, and therefore, trees adjust for increasing height by adding mass to adjust stem form. But the wood science literature points to considerable variance in stiffness with respect to green wood density. METHODS: Using the vast global repository of green wood mechanical properties, we compared relative stiffness and relative strength between taller and shorter species. For North American trees, we examined stem moisture distribution. KEY RESULTS: For all regions of the world, taller species on average possessed greater stiffness, but not strength, than shorter species of equal basic specific gravity. We looked for a possible universal mechanism that might allow taller tree species to adjust stiffness without affecting xylem specific gravity and concluded that the evidence points to a decrease in cellulose microfibril angle in structural cell walls combined with possible increases in holocellulose percentage. The evidence is strongest for conifers. We also showed that tall conifers have the ability to adjust the distribution of xylem moisture to maximize conduction while minimizing column load. CONCLUSIONS: Our research reveals that taller trees have developed internal stem adjustments to minimize diameter increase while attaining ever-greater heights, thus enabling these taller species to reduce energy expended on biomass accumulation while gaining greater access to solar radiation.

AB - BACKGROUND: Home parenteral nutrition (HPN) provides life-sustaining treatment for people with chronic intestinal failure (CIF). Poor quality of life is reported in association with the burden of HPN and the underlying condition leading to intestinal failure (IF). However, levels of negative affect (NA), incorporating anxiety and depression, have not been reported in CIF. This study examined the occurrence and risk factors for NA in a large CIF population using the validated Hospital Anxiety & Depression Scale (HADS) and Multidimensional Scale of Perceived Social Support (MSPSS) questionnaires. METHODS: A survey pack including HADS and MSPSS were distributed to patients managed by a specialist IF center. Data from these measures were analyzed against factors including underlying disease, length of time receiving HPN, employment status, and demographics. RESULTS: Of 85 patients who completed this study, 56% had clinical levels of anxiety and/or depression. Linear regression analysis confirmed significant correlations between social support and HADS scores, with poorer perceived social support associated with higher levels of NA (-0.26 MSPSS + 33.24; R2 = 0.29; P < .0001). There were also significant associations between unemployment and higher anxiety (P = .004), depression (P = .008), and NA scores (P = .003). By contrast, there were no significant associations between patient age, duration of time receiving parenteral nutrition, pathophysiological mechanisms of CIF, and NA levels. CONCLUSIONS: Clinical anxiety and depression are common, affecting more than half of patients with CIF. Patients with poor social networks and those of working age who have ceased employment are particularly vulnerable and should be prioritized for psychological support because of their elevated risk. PMID- 30299549 TI - Analytic second derivatives for the efficient electrostatic embedding in the fragment molecular orbital method. AB - The analytic second derivatives of the energy with respect to nuclear coordinates are developed for restricted Hartree-Fock and density functional theory, based on the two-body fragment molecular orbital method (FMO) and combined with the electrostatic embedding potential, self-consistently determined by point charges for far separated fragments and electron densities for near fragments. The accuracy of the method is established with respect to FMO using the exact embedding potential based on electron densities and to full calculations without fragmentation. The computational efficiency of parallelization is measured on the K supercomputer and the method is applied to simulate infrared spectra of two proteins, Trp-cage (PDB: 1L2Y) and crambin (1CRN). The nature of the vibrations in the Amide I peak of crambin and the Tyr symmetric stretch peak in Trp-cage are analyzed in terms of localized vibrations. (c) 2018 Wiley Periodicals, Inc. PMID- 30299550 TI - Representation of DNA environment: Spiral staircase distribution function. AB - In the present study, we investigated the local structure of DNA and its environment using a new visualization technique. The spiral staircase distribution function (SSDF) is determined as two-dimensional density distribution of atoms of water and ligands in local reference frames linked with each base pair of poly-DNA molecule, either GC or AT. This property of SSDF provides opportunity to study sequence-specific binding of ions, peptides, and other agents derived from a molecular dynamics computer simulation. The spatial structure of double-stranded DNA environment in water solution containing either Mg2+ or Na+ ions was investigated using of SSDF. The distributions of ions around GC and AT base pairs are shown separately. It is observed that Mg2+ ions interact with DNA atoms by means of the layer of water molecules and penetrate into the major groove only. Na+ ions have a direct contact with DNA atoms and penetrate both into the major and minor grooves of DNA. (c) 2018 Wiley Periodicals, Inc.

AB - Gold-catalyzed intermolecular alkyne oxidation has attracted much synthetic attention, but mostly suffering undesired over-oxidation. Recent experiments demonstrated that over-oxidation could be dramatically suppressed in zinc(II) catalyzed intermolecular alkyne oxidation/C?H functionalization. By means of first-principle density functional theory calculations, we explored the mechanism of the M-catalyzed intermolecular alkyne oxidations (M = Zn(OTf)2 and Au+ PR3 ) as well as the effects of oxidants, temperature, and metal catalysts on chemoselectivity, in an effort to disclose the origin of the extraordinary chemoselectivity pertaining to zinc catalysis. Our calculations indicate that the Zn-catalyzed intermolecular alkyne oxidation/C?H functionalization proceeds by a Friedel-Crafts alkylation mechanism rather than metal carbene insertion mechanism. The chemoselectivity of C?H functionalization against over-oxidation in Zn catalysis, in comparison with gold catalysis, can be jointly controlled by four factors: (1) the use of less nucleophilic N-oxide, (2) the enhanced electrophilicity and carbocationic nature of the carbenic site in the alpha-oxo metal carbenoid intermediate, (3) enhanced steric repulsion to incoming oxidant exerted by bulky ancillary ligand in the close nearby of the carbenic site to disfavor intermolecular over-oxidation and (4) the large negative value of activation entropy in the intermolecular over-oxidation pathway, that jointly give rise to lower activation free energy for the intramolecular cyclization/C?H functionalization pathway than for the intermolecular over-oxidation pathway.

PMID- 30299553 TI - Defence-related priming and responses to recurring drought: Two manifestations of plant transcriptional memory mediated by the ABA and JA signalling pathways. AB - Collective evidence from agricultural practices and from scientific research has demonstrated that plants can alter their phenotypic responses to repeated biotic and abiotic stresses or their elicitors. A coordinated reaction at the organismal, cellular, and genome levels has suggested that plants can "remember" an earlier stress and modify their future responses, accordingly. Stress memory may increase a plant's survival chances by improving its tolerance/avoidance abilities and may provide a mechanism for acclimation and adaptation. Understanding the mechanisms that regulate plant stress memory is not only an intellectually challenging topic but has important implications for agricultural practices as well. Here, I focus exclusively on specific aspects of the transcription memory in response to recurring dehydration stresses and the memory type responses to insect damage in a process known as "priming." The questions discussed are (a) whether/how the two memory phenomena are connected at the level of transcriptional regulation; (b) how differential transcription is achieved mechanistically under a repeated stress; and (c) whether similar molecular and/or epigenetic mechanisms are involved. Possible biological relevance of transcriptional stress memory and its preservation in plant evolution are also discussed. PMID- 30299552 TI - A kinetics study of ligand substitution reaction on dinuclear platinum complexes: Stochastic versus deterministic approach. AB - The kinetics on a basic ligand substitution reaction on dinuclear platinum complexes [Pt(PEt3 )2 PhPt(PEt3 )2 ]2+ and [Pt(PEt3 )2 PhCOPhPt(PEt3 )2 ]2+ , with the ligands pyridine and 3-chloropyridine, is studied. This is a fundamental step in a self-assembly, and the time evolution has been observed with a new experimental technique, QASAP (quantitative analysis of self-assembly process), which is recently developed by Hiraoka's group. As a result of numerical calculations based on master equation, we succeed in specifying the reaction rate constants with a simple reaction model. In addition, the time evolutions of all the intermediate components produced and consumed in chemical reaction are revealed, including those unobserved in the experiments. The convergence behavior of the existence ratios of specific chemical species calculated with the stochastic algorithm method is compared with those obtained from deterministic formalism based on rate equations, revealing a clear dependence on the number of constituent molecules.

AB - Nitric oxide (NO) is an important defense molecule secreted by the squid Euprymna scolopes and sensed by the bacterial symbiont, Vibrio fischeri, via the NO sensor HnoX. HnoX inhibits colonization through an unknown mechanism. The genomic location of hnoX adjacent to hahK, a recently identified positive regulator of biofilm formation, suggested that HnoX may inhibit colonization by controlling biofilm formation, a key early step in colonization. Indeed, the deletion of hnoX resulted in early biofilm formation in vitro, an effect that was dependent on HahK and its putative phosphotransfer residues. An allele of hnoX that encodes a protein with increased activity severely delayed wrinkled colony formation. Control occurred at the level of transcription of the syp genes, which produce the polysaccharide matrix component. The addition of NO abrogated biofilm formation and diminished syp transcription, effects that required HnoX. Finally, an hnoX mutant formed larger symbiotic biofilms. This work has thus uncovered a host-relevant signal controlling biofilm and a mechanism for the inhibition of biofilm formation by V. fischeri. The study of V. fischeri HnoX permits us to understand not only host-associated biofilm mechanisms, but also the function of HnoX domain proteins as regulators of important bacterial processes.

PMID- 30299556 TI - Metabolic analysis of the melatonin biosynthesis pathway using chemical labeling coupled with liquid chromatography-mass spectrometry. AB - Characterization of the melatonin (MLT) biosynthesis pathway in plants is still limited. Additionally, a metabolomic analysis of MLT biosynthesis in plants is still a challenge due to analyte structural and chemical diversity, low analyte abundances, and plant matrix complexities. Herein, a sensitive liquid chromatography-mass spectrometry (LC-MS) method enabling the simultaneous determination of seven plant MLT biosynthetic metabolites was developed. In the proposed strategy, the targeted metabolites, which included tryptophan (Trp), tryptamine (TAM), 5-hydroxytryptophan (5HTP), serotonin (5HT), N-acetylserotonin (NAS), 5-methoxytryptamine (5MT), and MLT, were purified from plant extracts using a one-step dispersive solid-phase extraction (DSPE). The samples were then chemically labeled with dansyl chloride (DNS-Cl), followed by analysis using LC MS. The limit of detection (LOD) values ranged from 0.03 to 1.36 pg/mL and presented a 22- to 469-fold decrease when compared to the unlabeled metabolites. Due to the high sensitivity of the proposed method, the consumption of plant materials was reduced to 10 mg FW. Ultimately, the established method was utilized to examine the distributions of MLT and its intermediates in rice shoots and roots with or without cadmium (Cd) stress. The results suggested that under normal condition, MLT may also be generated via a Trp/TAM/5HT/5MT/MLT path (Pathway II) in addition to the previously reported Trp/TAM/5HT/NAS/MLT path (Pathway I), although Pathway I was shown to be dominant. During Cd stress, MLT was also shown to be produced through these two pathways, with Pathway II shown to be dominant in rice shoots and roots.

AB - OBJECTIVE: With more teeth retained for longer in an ageing population, population-wide periodontal treatment needs may increase. We assessed and projected periodontal treatment needs from 1997 to 2030 in Germany. METHODS: Partial-mouth probing-pocket depths (PPDs) from repeated waves (1997, 2005, 2014) of the nationally representative German Oral Health Studies were transformed into full-mouth PPDs via decision-tree-based ensemble-modelling. In line with German healthcare-regulations, teeth with PPD >= 4 mm were regarded as needing periodontal treatment. Weighted means were interpolated cross-sectionally by fitting spline-curves and then regressed longitudinally 1997-2030. RESULTS: In 1997, younger adults (35-44 years old) had a mean of 7.4 teeth needing treatment (overall 93.8 million teeth); this decreased to 4.8 teeth (47.3 million teeth) in 2014. For 2030, we project 3.2 teeth (33.7 million teeth). In seniors, an increase was recorded (1997: 4.5 teeth, 33.5 million teeth; 2014: 7.5 teeth, 63.4 million teeth); this is expected to continue until 2030 (to 12.2 teeth, 140.8 million teeth). The cumulative number of teeth needing treatment increased from 2000 (355 million) to 2015 (365 million), and will increase further to 2030 (464 million). CONCLUSIONS: Population-wide periodontal treatment needs may increase until 2030, mainly in the elderly. Concepts for addressing, these growing needs are required.

AB - Ab initio and density functional CCSD(T)-F12/cc-pVQZ-f12//B2PLYPD3/6-311G** calculations have been performed to unravel the reaction mechanism of triplet and singlet methylene CH2 with ketene CH2 CO. The computed potential energy diagrams and molecular properties have been then utilized in Rice-Ramsperger-Kassel-Marcus Master Equation (RRKM-ME) calculations of the reaction rate constants and product branching ratios combined with the use of nonadiabatic transition state theory for spin-forbidden triplet-singlet isomerization. The results indicate that the most important channels of the reaction of ketene with triplet methylene lead to the formation of the HCCO + CH3 and C2 H4 + CO products, where the former channel is preferable at higher temperatures from 1000 K and above. In the C2 H4 + CO product pair, the ethylene molecule can be formed either adiabatically in the triplet electronic state or via triplet-singlet intersystem crossing in the singlet electronic state occurring in the vicinity of the CH2 COCH2 intermediate or along the pathway of CO elimination from the initial CH2 CH2 CO complex. The predominant products of the reaction of ketene with singlet methylene have been shown to be C2 H4 + CO. The formation of these products mostly proceeds via a well-skipping mechanism but at high pressures may to some extent involve collisional stabilization of the CH3 CHCO and cyclic CH2 COCH2 intermediates followed by their thermal unimolecular decomposition. The calculated rate constants at different pressures from 0.01 to 100 atm have been fitted by the modified Arrhenius expressions in the temperature range of 300-3000 K, which are proposed for kinetic modeling of ketene reactions in combustion.

Parameterization for nickel with the spin-polarized DFTB3 model. AB - In this work, we explore the applicability and limitations of the current third order density functional tight binding (DFTB3) formalism for treating transition metal ions using nickel as an example. To be consistent with recent parameterization of DFTB3 for copper, the parametrization for nickel is conducted in a spin-polarized formulation and with orbital-resolved Hubbard parameters and their charge derivatives. The performance of the current parameter set is evaluated based on structural and energetic properties of a set of nickel containing compounds that involve biologically relevant ligands. Qualitatively similar to findings in previous studies of copper complexes, the DFTB3 results are more reliable for nickel complexes with neutral ligands than for charged ligands; nevertheless, encouraging agreement is noted in comparison to the reference method, B3LYP/aug-cc-pVTZ, especially for structural properties, including cases that exhibit Jahn-Teller distortions; the structures also compare favorably to available X-ray data in the Cambridge Crystallographic Database for a number of nickel-containing compounds. As to limitations, we find it is necessary to use different d shell Hubbard charge derivatives for Ni(I) and Ni(II), due to the distinct electronic configurations for the nickel ion in the respective complexes, and substantial errors are observed for ligand binding energies, especially for charged ligands, d orbital splitting energies and splitting between singlet and triplet spin states for Ni(II) compounds. These observations highlight that future improvement in intra-d correlation and ligand polarization is required to enable the application of the DFTB3 model to complex transition metal ions.

AB - Application of Alpha-oscillator theory to quantum electrodynamics (QED) solves the mystery (Feynman) of the double-slit phenomenon involved in the foundation of quantum mechanics (QM). Even if with the same initial condition given, different spots on the screen can be predicted deterministically with no introduction of hidden variables. The interference pattern is similar to, but cannot be reproduced quantitatively by, that of the QM wave function, contrary to many years-anticipation: a new prediction, awaiting experimental test over and above the Bohr-Einstein gedanken experiment. The general proof has already been published in Ref. [3a] and the concrete numerical algorithm of the extended normal mode technique for concrete trajectory of one electron in Ref. [3b]. In this article, (1) the new "interpretation" of the QED wave function is given in section "Interpretation of Wave Function in QED": the QED wave function used in the extended normal mode technique gives probability density distribution function of the initial values of trajectories. Moreover, (2) for the sake of demonstration of this new interpretation, the time-independent stationary state QM wave function is substituted to the QED wave function in section "Internal Self-Stress of Energetic Particles": the QED wave function is realized by internal self-stress revealed as energy density at the initial conditions. The renewed energy density is applied to study a unified scheme for generalized chemical reactivity. This is a new kind of chemical force acting in between electrons not in between nuclei. This paves a way for more advanced time dependent simulation of electronic structure and dynamics in chemical reaction dynamics by tracing trajectories of many electrons.

AB - : Cholangiocytes, the epithelial cells lining the biliary tree in the liver, express primary cilia that can detect several kinds of environmental signals and then transmit this information into the cell. We have previously reported that cilia are significantly reduced in cholangiocarcinoma (CCA) and that the experimental deciliation of normal cells induces a malignant-like phenotype with increased proliferation, anchorage independent growth, invasion and migration. Here, we tested the hypothesis that the chemosensory function of cholangiocyte primary cilia acts as a mechanism for tumor suppression. We found that in the presence of extracellular nucleotides, ciliary-dependent chemosensation of the nucleotides inhibited migration and invasion in normal ciliated cholangiocytes via a P2Y11 receptor and LKB1-PTEN-AKT dependent mechanism. In contrast, in normal deciliated cholangiocytes and CCA cells, the nucleotides induced the opposite effects, i.e. increased migration and invasion. As activation of LKB1 via a ciliary dependent mechanism was required for the nucleotide-mediated inhibitory effects on migration and invasion, we attempted to activate LKB1 directly, independent of ciliary expression, using the compound hesperidin methyl chalcone (HMC). We found that HMC induced activation of LKB1 in both ciliated and deciliated cells in vitro, resulting in the inhibition of migration and proliferation. Furthermore, using a rat syngeneic orthotopic CCA model, we found that HMC inhibited tumor growth in vivo. CONCLUSIONS: these findings highlight the importance of the chemosensory function of primary cilia for the control of migration and invasion, and suggest that by directly activating LKB1 and bypassing the need for primary cilia, it is possible to emulate this chemosensory function in CCA cells. These data warrant further studies for evaluating the possibility of using HMC as a novel therapy for CCA. This article is protected by copyright. All rights reserved.

AB - A practical and highly para-selective C-H difluoromethylation of aromatic ketones has been developed by employing tetrakis(triphenylphosphine)palladium(0) as the catalyst and triphenylphosphine as the ligand.

Moreover, a mechanistic study revealed that a palladium intermediate coordinated by a carbonyl group promotes highly para-selective difluoromethylation. PMID- 30299563 TI - Prognostic role of baseline 18 F-FDG PET/CT parameters in MALT lymphoma. AB - Mucosa-associated lymphoid tissue (MALT) lymphoma is an indolent lymphoma with good prognosis and variable fluorine-18 fluorodeoxyglucose (18 F-FDG) avidity. Many possible prognostic factors have been investigated with controversial results, but the possible prognostic role of 18 F-FDG positron emission tomography/computed tomography (PET/CT) remains unclear. Our aim was to evaluate the prognostic impact of qualitative and semiquantitative baseline PET/CT parameters on outcome of MALT lymphoma. We retrospectively enrolled 161 patients with histologically confirmed MALT lymphoma who underwent 18 F-FDG PET/CT before any treatment. PET images were qualitatively and semiquantitatively analyzed by measuring the maximum standardized uptake value body weight (SUVbw), lean body mass (SUVlbm), body surface area (SUVbsa), metabolic tumor volume (MTV), and total lesion glycolysis (TLG). The Kaplan-Meier method was used to estimate the progression-free survival (PFS) and overall survival (OS) times. Cox regression models were performed to determine the relation between PET/CT features and OS and PFS. Ninety-eight patients had positive 18 F-FDG PET/CT showing 18 F-FDG uptake (mean SUVbw, 10.1; SUVlbm, 7.2; SUVbsa, 2.7; MTV, 88.8; and TLG, 526); the remaining 63 were not 18 F-FDG avid. 18 F-FDG avidity was significantly correlated with tumor size and Ki-67 score. Relapse/progression of disease occurred in 47 patients with an average time of 40.2 months; death occurred in 12 patients with an average of 59 months. At a median follow-up of 62 months, median PFS and OS were 52 and 62 months, respectively. Advanced tumor stage and extragastric site were demonstrated to be independent prognostic factors for PFS, while only tumor stage for OS. Instead, PET/CT parameters were not related to survival, despite positive correlation at univariate analysis between MTV and TLG with PFS and positive PET/CT with PFS and OS. In conclusion, a 61% rate of PET avidity in biopsy-confirmed MALT lymphoma was found, and it was correlated with tumor size and Ki-67 score. Only tumor stage and localization were independently correlated with PFS and OS. PMID- 30299565 TI - Computational insight into excited states of the ring-opening radicals from the pyrolysis of furan biofuels. AB - The low-lying valence excited states and Rydberg states of the radical species from the ring-opening reactions in pyrolysis of furan biofuels have been determined by extensive density functional theory and sophisticated wave function theory calculations. The radicals 1-C4 H5 O-2, 2-furylCH2 , and 4-C6 H7 O with the delocalized pi-type single electron are predicted to be most stable among the reactive species here for furan, 2-methyfuran, and 2,5-dimethylfuran, respectively. Predicted vertical transition energies by TD-CAM-B3LYP show good agreement with those by CASPT2. Some among the electronic excitations to low lying states can take place in the visible light region, and they may be involved in the combustion process. Further surface hopping dynamics simulations on the excited states of the most stable ring-opening radical 1-C4 H5 O-2 of furan as an example reveal that 89.9% sampling trajectories at the initial excited state of 22 A"(pi1 pi*2 ) decay to the 12 A'(n1 pi*2 ) state within an average of 384 fs, and then 81.2% trajectories at the 12 A' state go to the ground state within an average of 114 fs. At the end of the simulation for 1000 fs, 18.8% trajectories still stay on the excited states of 22 A" and 12 A', suggesting that the reactive radicals in the ground state are mainly responsible for the combustion chemistry of furan biofuels.

The 1:1 and 1:2 reactions of P4 with 1 afford Bn P4 cages (2: n=2, 3: n=4), whereas a stoichiometric mixture of 1 and B2 cat2 undergoes homonuclear catenation through the addition of the B-B sigma bond of B2 cat2 across the B=B double bond of 1 (i.e. diboration), which leads to the formation of a tetraborane (4) featuring a B4 chain. PMID- 30299566 TI - Ex vivo evaluation of the efficacy of canine fresh-frozen plasma thawed using a microwave plasma defroster. AB - BACKGROUND: Commercial microwave plasma defrosters (MPDs) are used globally in human medicine to safely thaw fresh-frozen plasma (FFP), but this technology has never been tested in a veterinary setting. This study was undertaken to assess the efficacy of a commercial MPD for the rapid thawing of canine FFP. STUDY DESIGN: Twenty-three units (twelve 120 mL and eleven 240 mL) of canine FFP were thawed using an MPD. Time-to-thaw and pre- and postthawing temperatures of the units were measured. Clotting factor activities (factors II, V, VII, VIII, IX, X, and von Willebrand factor), fibrinogen concentrations, prothrombin times, and activated partial thromboplastin times were measured. KEY FINDINGS: The evaluated MPD effectively thaws plasma quickly for both 120 mL units (2.7 +/- 0.08 min) and 240 mL units (3.9 +/- 0.15 min) while maintaining clinically relevant activities of clotting factors and fibrinogen concentration. While some measurements of factor VIII activity fell below the reference interval, none fell below 40%. One 240 mL unit had von Willebrand factor activity <70%. There was no evidence of excessively heated plasma to indicate a safety concern. SIGNIFICANCE: The MPD evaluated in this study provides a useful means to rapidly thaw canine FFP for correction of factor-deficient coagulopathy. PMID- 30299567 TI - Nonsurgical management of traumatic pneumoperitoneum in a cat. AB - OBJECTIVE: To describe the nonsurgical management of a cat with traumatic pneumoperitoneum. CASE SERIES SUMMARY: A 4-year-old cat was presented following vehicular polytrauma. Thoracic radiographs revealed 4 rib fractures, a scapular fracture, and pneumothorax. Abdominal ultrasound revealed a small volume of free abdominal fluid. Computed tomography showed a mild pneumoretroperitoneum and a pneumoperitoneum in the region of the porta hepatis. The cat was managed conservatively with close monitoring. Exploratory laparotomy was not pursued given patient stability and static serial imaging studies revealing no indications for surgical intervention. After 6 days, the pneumoperitoneum was no longer detectable. NEW OR UNIQUE INFORMATION PROVIDED: To the authors' knowledge, this is the first report of successful nonsurgical management of traumatic pneumoperitoneum in a cat. PMID- 30299568 TI - Determining prognosis in canine sepsis by bedside measurement of cell-free DNA and nucleosomes. AB - OBJECTIVE: To investigate the use of plasma cell-free DNA (cfDNA) and nucleosome concentrations as prognostic biomarkers in canine sepsis. DESIGN: Prospective, observational cohort study conducted from June 2015 to February 2016. SETTING: University teaching hospital. ANIMALS: Forty-five dogs with sepsis, 10 dogs with nonseptic systemic inflammatory response syndrome (nSIRS), and 15 healthy controls were consecutively enrolled and followed to hospital discharge. Patients were eligible for enrollment if they met >=2 SIRS criteria and had a documented or highly suspected bacterial infection. Dogs <3 kg or with a known coagulopathy were excluded. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Acute Patient Physiology and Laboratory Evaluation scores (APPLE) were calculated and outcomes recorded. Plasma cfDNA was measured using a benchtop fluorimeter. Plasma nucleosome concentrations were determined by ELISA. Plasma nucleosome and cfDNA concentrations in dogs with sepsis or nSIRS were compared to those of healthy controls and cfDNA concentrations in septic dogs with and without bacteremia were compared. Associations between cfDNA concentrations and nucleosomes, leukocyte count, neutrophil count, and APPLE scores were evaluated. For septic dogs, cfDNA concentrations relative to neutrophil count and nucleosome concentrations in survivors and nonsurvivors were compared. Alpha was set at 0.05. cfDNA concentrations were significantly higher in dogs with sepsis or nSIRS compared to healthy controls (P < 0.0001 and P = 0.0034, respectively). Nucleosome concentrations were significantly higher in dogs with sepsis compared to healthy controls (P = 0.007). There was limited association between cfDNA and nucleosome concentrations (rs = 0.266), and no association between cfDNA concentration and leukocyte count, neutrophil count, and APPLEfull scores. Concentrations of cfDNA were positively correlated with APPLEfast score (rs = 0.335, P = 0.025); however, cfDNA concentrations were significantly higher in dogs with bacteremia (P = 0.0299). In dogs with sepsis, cfDNA concentrations relative to neutrophil count were significantly higher in nonsurvivors than in survivors (P = 0.008). CONCLUSIONS: In dogs with sepsis, high cfDNA concentrations relative to neutrophil count are associated with nonsurvival. Point-of-care cfDNA measurement may aid identification of bacteremia.

AB - Targeting overexpressed receptors on the cancer cells with radiolabeled peptides has become very important in nuclear oncology in the recent years. Peptides are small and have easy preparation and easy radiolabeling protocol with no side effect and toxicity. These properties made them a valuable tool for tumor targeting. Based on the successful imaging of neuroendocrine tumors with 111 In octreotide, other receptor-targeting peptides such as bombesin (BBN), cholecystokinin/gastrin analogues, neurotensin analogues, glucagon-like peptide 1, and RGD peptides are currently under development or undergoing clinical trials. The most frequently used radionuclides for tumor imaging are 99m Tc and 111 In for single-photon emission computed tomography and 68 Ga and 18 F for positron emission tomography imaging. This review presents some of the 99m Tc labeled peptides, with regard to their potential for radionuclide imaging of tumors in clinical and preclinical application. PMID- 30299571 TI - In vitro hemolysis of stored units of canine packed red blood cells. AB - BACKGROUND: Hemolysis is an important quality parameter of packed red blood cells (pRBCs) that is used to assess the cellular integrity of stored blood units. According to human standards, hemolysis at the end of storage must not exceed 1%, as otherwise it may be responsible for decreased transfusion effectiveness and acute life-threatening reactions. OBJECTIVES: This prospective study was designed to evaluate the hemolysis of canine pRBCs stored in an additive solution containing adenine, dextrose, mannitol, and sodium chloride, and to assess its associations with storage time, duration of the collection process, collection disturbances, and with the final volume and PCV of the pRBCs units. METHODS: One hundred eighty pRBCs units were collected from canine donors. Hemolysis of the pRBCs units was determined immediately after processing (t = 0). The units were then stored and retested (t = 1) either before administration (during weeks 2, 3, 4, 5, or 6 of storage) or at the end of the storage period (42 d) if not used. RESULTS: Mean hemolysis at t = 0 was 0.09% (SD 0.06) and increased during storage, at a more pronounced rate from the 5th (mean values of 0.52%, SD 0.29) to the 6th week (1.2%, SD 0.72). Almost 51% of the units with 36-42 days of shelf life showed more than 1% hemolysis. Disturbances in the collection process, the volume of the whole blood units, and the volume of stored pRBCs units or their PCV were not related to pRBCs hemolysis. CONCLUSIONS: According to human blood bank recommendations regarding acceptable hemolysis, canine pRBCs stored for more than 35 days should be tested to ensure <1% hemolysis prior to administration.

PMID- 30299574 TI - Multiple roles and diverse regulation of the Ras/cAMP/protein kinase A pathway in Candida albicans. AB - Candida albicans is a major fungal pathogen of humans, causing both superficial and life-threatening systemic infections in immunocompromised people. The conserved Ras/cAMP/PKA pathway plays a key role in regulating multiple traits important for the virulence of C. albicans such as cell growth, yeast-hyphal transition, white-opaque switching, sexual reproduction and biofilm development. Diverse external signals influence cell physiology by activating this signaling pathway. The key components of the Ras/cAMP/PKA pathway include two Ras GTPases (Ras1 and Ras2), an adenylyl cyclase (Cyr1, also known as Cdc35), two cyclic nucleotide phosphodiesterases (Pde1 and Pde2) and the catalytic (Tpk1 and Tpk2) and regulatory (Bcy1) subunits of PKA kinase. Activation of this pathway dramatically alters the gene expression profile via several transcription factors, leading to the activation of specific biological processes. Here, we review the progress made in the past two decades to elucidate the molecular mechanisms by which the Ras/cAMP/PKA pathway senses diverse environmental cues and controls specific cellular responses and its connection with other signaling pathways in C. albicans.

AB - Volatile components in Dalbergia cochinchinensis Pierre were analysed using a comprehensive two-dimensional gas chromatography with mass spectrometry method featuring a new solid-state modulator. Compared to one-dimensional gas chromatography, the number of detected peaks were significantly increased. A total of 45 major compounds were identified in this study and the forward and reverse match factors of these compounds were both above 800. The results showed that the volatile components in Dalbergia cochinchinensis Pierre were primarily aldehyde and ketone compounds such as benzaldehyde, cinnamaldehyde, 4-chromanone, 1-(2-hydroxyphenyl)ethanone and acetophenone. In addition, a semi-quantitative analysis was conducted to determine the contents of the detected compounds based on peak area percentage. Moreover, the repeatability of the comprehensive two dimensional gas chromatography-mass spectrometry analysis in this study was quite satisfactory with relative standard deviations less than 12.7% for intraday and 17.3% for interday measurements.

PMID- 30299578 TI - Multiple Sources for Sertoli Cells and Two Sertoli Phenotypes in the Adult Elasmobranch Testis: Insight from Two Species Belonging to Different Orders. AB - Findings presented here for the chondrichthyans Prionace glauca and Isurus oxyrinchus show that the assembly of the spermatocyst and it's attached collecting duct are seamlessly connected developmental phenomena. The cyst's somatic cell component (i.e., Sertoli cells, SCs) and the duct's constituent cells derive both from a common precursor cell type (typically a large oblong cell) found among the A-spermatogonia in the folliculogenic region. Novel findings show that the co-developing collecting duct itself serves also as a source of either normal-looking or basophilic atypical SCs (aSCs), depending on whether the duct-cyst transition remains mitotically active and open, or is sealed. The aSCs arise from accumulating slender basophilic cells at the duct cyst interface after which the newly formed cyst is sealed. Quantitative analysis of the latter in P. glauca revealed a correlation between the appearance of this aSC in immature cysts and the degenerated testicular condition that displays a gradient of multinucleate cell (MNC) death among spermatogonial cysts. Findings seem to implicate these aSCs in the life-death balance in mature spermatogonial cohorts downstream in the spermatogenic sequence, rather than in newly formed cysts that exhibit low rates of apoptosis. Photomicrographs of developing spermatogonial cysts showing several aSCs interspersed among cytoplasmically linked spermatogonia that are proliferating or have died, seem to suggest that these small SCs may be involved in confining MNC death to a given cyst region under conditions of subthreshold levels of apoptosis such as to ensure cyst recovery in immature spermatogonial cysts.

AB - A series of genistein derivatives were synthesized and evaluated as multifunctional anti-Alzheimer agents.

A Lineweaver-Burk plot and molecular modeling study showed that compound 5a targeted both the catalytic active site and the peripheral anionic site of AChE. These compounds also showed potent peroxy scavenging activity and metal-chelating ability. The compounds did not show obvious effect on HepG2 and PC12 cell viability at the concentration of 100 MUM. Therefore, these genistein derivatives can be utilized as multifunctional agents for the treatment of AD. PMID- 30299584 TI - Activation of transient receptor potential vanilloid 3 channel (TRPV3) aggravated pathological cardiac hypertrophy via calcineurin/NFATc3 pathway in rats. AB - Cardiac hypertrophy is a compensatory response to mechanical stimuli and neurohormonal factors, ultimately progresses to heart failure. The proteins of some transient receptor potential (TRP) channels, Ca2+ -permeable nonselective cation channel, are highly expressed in cardiomyocytes, and associated with the occurrence of cardiac hypertrophy. Transient receptor potential vanilloid 3 (TRPV3) is a member of TRP, however, the functional role of TRPV3 in cardiac hypertrophy remains unclear. TRPV3 was elevated in pathological cardiac hypertrophy, but not in swimming exercise-induced physiological cardiac hypertrophy in rats. TRPV3 expression was also increased in Ang II-induced cardiomyocyte hypertrophy in vitro, which was remarkably increased by carvacrol (a nonselective TRPV channel agonist), and reduced by ruthenium red (a nonselective TRPV channel antagonist). Interestingly, we found that activated TRPV3 in Ang II-induced cardiomyocyte hypertrophy was accompanied with increasing intracellular calcium concentration, promoting calcineurin, and phosphorylated CaMKII protein expression, and enhancing NFATc3 nuclear translocation. However, blocking or knockdown of TRPV3 could inhibit the expressions of calcineurin, phosphorylated CaMKII and NFATc3 protein by Western blot. In conclusion, the activation of TRPV3 aggravated pathological cardiac hypertrophy through calcineurin/NFATc3 signalling pathway and correlated with the protein expression levels of calcineurin, phosphorylated CaMKII and NFATc3, revealing that TRPV3 might be a potential therapeutic target for cardiac hypertrophy.

PMID- 30299585 TI - Altered VEGF Signaling Leads to Defects in Heart Tube Elongation and Omphalomesenteric Vein Fusion in Quail Embryos. AB - Formation of the endocardial and myocardial heart tubes involves precise cardiac progenitor sorting and tissue displacements from the primary heart field to the embryonic midline-a process that is dependent on proper formation of conjoining great vessels, including the omphalomesenteric veins (OVs) and dorsal aortae. Using a combination of vascular endothelial growth factor (VEGF) over- and under activation, fluorescence labeling of cardiac progenitors (endocardial and myocardial), and time-lapse imaging, we show that altering VEGF signaling results in previously unreported myocardial, in addition to vascular and endocardial phenotypes. Resultant data show: (1) exogenous VEGF leads to truncated endocardial and myocardial heart tubes and grossly dilated OVs; (2) decreased levels of VEGF receptor 2 tyrosine kinase signaling result in a severe abrogation of the endocardial tube, dorsal aortae, and OVs. Surprisingly, only slightly altered myocardial tube fusion and morphogenesis is observed. We conclude that VEGF has direct effects on the VEGF receptor 2-bearing endocardial and endothelial precursors, and that altered vascular morphology of the OVs also indirectly results in altered myocardial tube formation.

The arsenolysis reaction is irreversible due to the hydrolysis of the resulting alpha-D-ribose-1 arsenate. As a result, the desired products are formed in near-quantitative yields, as indicated by high-performance liquid chromatography (HPLC) analysis, and can easily be isolated.

AB - AIMS: Heart failure (HF) is a common co-morbidity in non-valvular atrial fibrillation (NVAF) patients and a potent risk factor for stroke, bleeding, and a decreased time-in-therapeutic range with warfarin. We assessed the real-world effectiveness and safety of rivaroxaban and warfarin in NVAF patients with co morbid HF. METHODS AND RESULTS: Using US Truven MarketScan Commercial and Medicare supplemental database claims data from 11/2011 to 12/2016, we identified oral anticoagulant (OAC)-naive NVAF patients with HF (International Classification of Diseases, 10th Revision codes of I50 or I09.81) and >=12 months of insurance coverage prior to the qualifying OAC dispensing. Rivaroxaban users (20 or 15 mg once daily) were 1:1 propensity score matched to warfarin users, with residual absolute standardized differences <0.1 being achieved for all covariates after matching. Patients were followed up until an event, OAC discontinuation/switch, insurance disenrolment, or end of follow-up. Rates [events per 100 person-years (PYs) of follow-up] for stroke or systemic embolism and major bleeding (using the Cunningham algorithm) were compared between the matched cohorts using Cox proportion hazard regression and reported as hazard ratios (HRs) with 95% confidence intervals (CIs). We matched 3418 rivaroxaban (32% receiving the reduced dose) and 3418 warfarin users with NVAF and HF with a median (interquartile range) available follow-up of 1.4 (0.6, 2.5) years. Median age was 74 (63, 82) years, and median CHA2 DS2 -VASc and HASBLED scores were 4 (3, 5) and 2 (2, 3). Common HF medications included beta-blockers (64%), angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (62%), loop diuretics (46%), digoxin (11%), and aldosterone receptor antagonists (10%). The hazard of developing stroke or systemic embolism (0.98 events/100PY vs. 1.28 events/100PY; HR = 0.82, 95% CI = 0.47-1.44), ischaemic stroke (0.70 events/100PY vs. 1.02 events/100PY; HR = 0.77, 95% CI = 0.41-1.46), or major bleeding (3.86 events/100PY vs. 4.23 events/100PY; HR = 0.98, 95% CI = 0.73-1.31) was not found to be different between rivaroxaban and warfarin users. Intracranial haemorrhage was infrequent in both cohorts and numerically less with rivaroxaban (0.27 events/100PY vs. 0.36 events/100PY; HR = 0.73, 95% CI = 0.25-2.08). CONCLUSIONS: Effectiveness and safety of rivaroxaban vs. warfarin are sustained in NVAF patients with co-morbid HF treated in routine practice. The general consistency between this real-world study and those from phase III randomized trial data of rivaroxaban should provide additional reassurance to clinicians regarding the use of rivaroxaban in NVAF patients with HF.

AB - Arteries supplying the intermandibular, mental, masseteric, buccal, labial, and nasal regions of the face in selected species belonging to the suborder Tylopoda are described in this study. Analyses were conducted on a total of five species representing the family Camelidae based on 27 heads of cadaveric specimens, which were prepared by arterial injection with acetone-dissolved stained vinyl super chloride or stained latex LBS3060. Vascularization of regions of the face was formed by the facial, sublingual, mental, transverse facial, buccal, and infraorbital arteries. It was confirmed that the linguofacial trunk is absent in Camelidae. In turn, in camels the deep temporal artery descended in the common trunk with the transverse facial artery, while in llamas and alpacas it was a direct branch of the maxillary artery. It was shown that the pattern of facial arteries in Camelidamorpha exhibits specific traits for this clade and differs from the system of these arteries in other artiodactyls. The described specific character in arterial vascularization of the face not only expands the spectrum of morphological characteristics in Camelidae, but it also provides information which may prove useful for clinical purposes in veterinary practice.

AB - Chondroitin sulfate is a glycosaminoglycan involved in maintaining the morphofunctional properties of the extracellular matrix in peripheral nerves, but its distribution in human sensory corpuscles is unknown despite the role of extracellular matrix in mechanotransduction and axonal guidance. In this study we used immunohistochemistry to analyze the distribution of chondroitin sulfate in human cutaneous Meissner and Pacinian corpuscles. Chondroitin sulfate expression was absent from Meissner corpuscles. In Pacinian corpuscles chondroitin sulfate was found associated to a CD34 positive endoneurial-related layer, interposed between the S100 protein positive inner core cells, and the vimentin positive inner core and outer core-capsule cells. Therefore, the intermediate CD34+/chondroitin sulfate+ intermediate layer present in Pacinian corpuscles isolates the neural segment of the corpuscles (axon and inner core) from the non neural segments (outer core and capsule). These results suggest a role of chondroitin sulfate in the proper axonal growth and guidance, within the neuronal compartment of the Pacinian corpuscles during development and reinnervation, can be hypothesized. Moreover, a role of CS in mechanotransduction cannot be ruled out. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30299594 TI - Order in Disorder as Observed by the "Hydrophobic Cluster Analysis" of Protein Sequences. AB - Hydrophobic cluster analysis (HCA) is an original approach for protein sequence analysis, which provides access to the foldable repertoire of the protein universe, including yet unannotated protein segments ("dark proteome"). Foldable segments correspond to ordered regions, as well as to intrinsically disordered regions (IDRs) undergoing disorder to order transitions. In this review, how HCA can be used to give insight into this last category of foldable segments is illustrated, with examples matching known 3D structures. After reviewing the HCA principles, examples of short foldable segments are given, which often contain short linear motifs, typically matching hydrophobic clusters. These segments become ordered upon contact with partners, with secondary structure preferences generally corresponding to those observed in the 3D structures within the complexes. Such small foldable segments are sometimes larger than the segments of known 3D structures, including flanking hydrophobic clusters that may be critical for interaction specificity or regulation, as well as intervening sequences allowing fuzziness. Cases of larger conditionally disordered domains are also presented, with lower density in hydrophobic clusters than well-folded globular domains or with exposed hydrophobic patches, which are stabilized by interaction with partners. PMID- 30299595 TI - Pim-1 Expression in Rat Retina and its Changes after Optic Nerve Crush. AB - Pim-1 is a proto-oncogene which has been discovered to involve in cell proliferation, differentiation, and survival. In this study, we observed the expression of Pim-1 in neonatal and adult rat retina and the changes in rat retina following optic nerve crush (ONC) in order to explore the relationship between Pim-1 and the survival of retinal ganglion cells (RGC). We discovered that Pim-1 was distributed mainly in retinal pigment epithelial cells (RPE) and retinal ganglion cell layer (GCL) in normal newborn rats, and it appeared in RPE, cone rod cell layer and GCL in normal adult rats by immunohistochemistry. Our double immunofluorescent staining of Pim-1 and gamma-synuclein further confirmed that Pim-1 was localized in 80% of RGC. Moreover, we found that the amount of Pim 1 mRNA and protein in adult rat retina was transiently increased after ONC and then decreased 2 weeks after ONC, and the expression level was lower than that of neonatal rat retina under all conditions. We also discovered that Pim-1 expression in GCL detected by immunohistochemistry was upregulated at Day 1 and Day 3 after ONC, but downregulated at Day 14 after ONC when the survival of RGC was decreased and the apoptotic cells in GCL were increased by hematoxylin-eosin staining, immunohistochemistry, and TUNEL detection. We suggest that the overexpression of Pim-1 in the RGC is related to the optic nerve repair while the low expression of Pim-1 in RGC may be associated with apoptosis and weak intrinsic regeneration ability of RGC.

AB - Injuries to the peripheral nerves result in loss of motor, sensory and autonomic functions in the denervated segments of the body, thus having strong impact in the quality of life of affected patients. Neurons are able to regenerate their injured axons in the peripheral nerves; however, the endogenous repair mechanisms usually do not allow for a satisfactory functional recovery, especially after severe nerve injuries. The interest on regeneration after peripheral nerve injuries has increased in the recent years due to the numerous advances derived from studies of neurobiology, cell therapy, and tissue engineering. This Thematic Papers Issue brings together a number of papers, authored by researchers in the field, which cover a wide spectrum of topics related to regeneration and repair of peripheral nerve injuries. The Issue proposal originated from the recent 4th International Symposium on Peripheral Nerve Regeneration (ISPNR2017) which was hosted by Xavier Navarro and the European Society for the Study of Peripheral Nerve Repair and Regeneration in Barcelona, Spain.

AB - Both diabetes and breast cancer are common diseases worldwide, and diabetes is also linked to higher rates of breast cancer. Epidemiological data also indicate that diabetes may be one of the risk factors for breast cancer. However, the effect of diabetes on breast cancer progression in vivo is rarely reported. We established an ideal animal model of breast cancer using transgenic MMTV-PyMT mice, which spontaneously developed breast cancer. In this model, the animals copresented with diabetes mellitus, which allowed us to study the effect of high glucose on breast cancer. Compared with MMTV-PyMT mice without diabetes, MMTV PyMT mice with diabetes developed heavier tumors and exhibited greater tumor volumes. Furthermore, high glucose promoted the invasiveness and metastasis of breast cancer in MMTV-PyMT mice. This breast cancer model in which mice copresented with diabetes provides a useful tool to study the effect of diabetes on breast cancer. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30299598 TI - Three-Dimensional Musculoskeletal Modeling of the Sauropodomorph Hind Limb: The Effect of Postural Change on Muscle Leverage. AB - The biomechanical constraints for life at massive size can be directly observed in the evolutionary history of sauropodomorph dinosaurs. Members of this lineage underwent a number of major postural transitions as they increased in size from relatively small bipedal dinosaurs to massive titanosaurs that include the largest terrestrial animals of all time. To better understand the impact of gigantic size on the biomechanics of sauropods, we used three-dimensional musculoskeletal modeling to investigate how hind limb musculature was affected, first by the development of a quadrupedal stance from a bipedal one, and later in the transition from a narrow-gauge to a wide-gauge stance. Muscle moment arms were measured in four sauropodomorph taxa: the bipedal basal sauropodomorph Plateosaurus engelhardti, the narrow-gauge diplodocid Diplodocus carnegii, the titanosauriform Giraffatitan brancai, and the wide-gauge titanosaur Diamantinasaurus matildae. In Plateosaurus, low moment arm leverage in the hip extensors and knee flexors and extensors was observed suggesting high-velocity movement for fast locomotion. A reduction in hip extensor leverage in Diamantinasaurus was found which suggests a reduced role for the hind limb in forward propulsion in titanosaurs. An increase in overall hip adductor leverage and leverage of adductors 1 and 2 in Diamantinasaurus, compared with other taxa studied, might relate to the development of a wide-gauge stance. High knee flexor extensor leverage in Giraffatitan but not Diamantinasaurus partially refutes the idea that broader femoral condyles in titanosauriforms increased knee torque production capabilities. Sauropodomorph postural changes clearly had an impact on the function and leverage of hind limb muscles. Anat Rec, 2018. (c) 2018 Wiley Periodicals, Inc. PMID- 30299599 TI - Enhancement of Vascular Smooth Muscle Contractility by Alterations of Membranous Architecture. AB - Plasma membrane (PM) of smooth muscle cells hosts channel molecules regulating the flow of various ions. An intact architecture of PM is essential to orchestrate proper channel functions in order to complete agonist-mediated contraction, which includes Ca2+ release from the sarcoplasmic reticulum (SR) to initiate contraction, and subsequent Ca2+ refilling into SR through PM to sustain muscle contraction. The Junctional Complex (JC), comprising of junctional SR, and its apposing PM and neighboring caveolae, provides a quasi-enclosed microdomain housing receptors as well as ion channels and also restricting ion diffusions into the cytosol so the cell achieves optimal performance. The spatial arrangement of the JC is believed to ensure an uninterrupted Ca2+ cycling route. Full understanding of the functional role of the JC is the key to elucidating the contractile mechanisms of vascular smooth muscle and the physiological function of vessel contraction. The JC can be further divided into two sub-divisions, namely the PM-SR and caveolar regions. Previously, we demonstrated the role of the PM-SR region in the initiation of muscle contraction using pharmacological tools on the inferior vena cava (IVC) of rabbit. In the current study, we further dissected the caveolar region using a cholesterol-disrupting agent to investigate the role of the caveolar region. We conclude that disruption of the caveolar region in rabbit IVC smooth muscle results in augmented muscle contraction in response to adrenergic stimulation and the altered Ca2+ signaling may underlie the augmented contractility.

PMID- 30299600 TI - Rationale and design of the EU-CERT-ICD prospective study: comparative effectiveness of prophylactic ICD implantation. AB - AIMS: The clinical effectiveness of primary prevention implantable cardioverter defibrillator (ICD) therapy is under debate. The EUropean Comparative Effectiveness Research to Assess the Use of Primary ProphylacTic Implantable Cardioverter Defibrillators (EU-CERT-ICD) aims to assess its current clinical value. METHODS AND RESULTS: The EU-CERT-ICD is a prospective investigator initiated non-randomized, controlled, multicentre observational cohort study performed in 44 centres across 15 European Union countries. We will recruit 2250 patients with ischaemic or dilated cardiomyopathy and a guideline indication for primary prophylactic ICD implantation. This sample will include 1500 patients at their first ICD implantation and 750 patients who did not receive a primary prevention ICD despite having an indication for it (non-randomized control group). The primary endpoint is all-cause mortality; the co-primary endpoint in ICD patients is time to first appropriate shock. Secondary endpoints include sudden cardiac death, first inappropriate shock, any ICD shock, arrhythmogenic syncope, revision procedures, quality of life, and cost-effectiveness. At baseline (and prior to ICD implantation if applicable), all patients undergo 12 lead electrocardiogram (ECG) and Holter ECG analysis using multiple advanced methods for risk stratification as well as detailed documentation of clinical characteristics and laboratory values. Genetic biobanking is also organized. As of August 2018, baseline data of 2265 patients are complete. All subjects will be followed for up to 4.5 years. CONCLUSIONS: The EU-CERT-ICD study will provide a necessary update about clinical effectiveness of primary prophylactic ICD implantation. This study also aims for improved risk stratification and patient selection using clinical and ECG risk markers. PMID- 30299604 TI - [in process]. PMID- 30299605 TI - [in process].

AB - The taxonomic composition of microbial communities of Lake Baikal surface microlayer was studied by pyrosequencing of the 16S rDNA amplicons. Statistically reliable differences were found between bacterioneuston of the shallow and deep water stations. The shallow station community was characterized by higher diversity than the deep-water one. While bacterioneuston communities were shown to be less diversethan the water column communities, their diversity was comparable to that of other biofilm associations. Microbial communities of Lake Baikal surface microlayer were shown to be similar to those of the water column in the composition of predominant phyla, while differing considerably at the genus level. Bacterioneuston of Lake Baikal was comparable to microbial communities of the surface microlayer of other freshwater basins, although it was characterized by high abundance of the Alphaproteobacteria and Verrucomicrobia. High abundance of photoheterotrophs compared to the water column communities of other freshwater basins was another distinctive feature of Lake Baikal bacterioneuston. Our results showed the Lake Baikal surface microlayer to be a specific microbial community with low species diversity and relatively high abundance of photoheterotrophic microorganisms.

AB - Yeast abundance and species diversity of endophytic complexes in galls (cecidia) formed on the leaves of Salix fragilis, Salix caprea, Quercus robur, Tilia cordata, and Ulmus laevis and the epiphytic yeast communities of undamaged leaves of these plants were studied. Dynamics of yeast abundance in the galls was significantly different from that of the epiphytic yeast communities. Maximum numbers of endophytic yeastcells in the galls (up to 104 CFU/g) were comparable to abundance of epiphytic yeasts. A total of 14 species of endophytic yeasts were isolated from galls of different plants. Ascomycetous yeasts were found to predominate in the insect galls on willows and oak, while basidiomycetous yeasts dominated in mite galls on linden and elm, as well as on plant leaves. These results indicate that gall formation may be considered not only as abidirectional pathological process of the interaction between plants and invertebrates, but also as a process in which the endophytic microbial population of the galls plays an important role.

The major types of isolated organisms were identified using phenotypic and molecular biological approaches. Dispersion analysis revealed that the ontogenesis stage and plant organ were the factors with the greatest effect on the taxonomic structure of the communities. The dominantmicroorganisms of weeds were similar to those of cultivated plants. The minor components revealed in the spectra of bacterial communities of weeds belonged to poorly studied genera of chemolithotrophic proteobacteria.

PMID- 30299884 TI - European Society of Endocrinology Clinical Practice Guidelines on the management of adrenocortical carcinoma in adults, in collaboration with the European Network for the Study of Adrenal Tumors AB - Adrenocortical carcinoma (ACC) is a rare and in most cases steroid hormone producing tumor with variable prognosis. The purpose of these guidelines is to provide clinicians with best possible evidence-based recommendations for clinical management of patients with ACC based on the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. We predefined four main clinical questions, which we judged as particularly important for the management of ACC patients and performed systematic literature searches: (A) What is needed to diagnose an ACC by histopathology? (B) Which are the best prognostic markers in ACC? (C) Is adjuvant therapy able to prevent recurrent disease or reduce mortality after radical resection? (D) What is the best treatment option for macroscopically incompletely resected, recurrent or metastatic disease? Other relevant questions were discussed within the group. Selected Recommendations: (i) We recommend that all patients with suspected and proven ACC are discussed in a multidisciplinary expert team meeting. (ii) We recommend that every patient with (suspected) ACC should undergo careful clinical assessment, detailed endocrine work-up to identify autonomous hormone excess and adrenal-focused imaging. (iii) We recommend that adrenal surgery for (suspected) ACC should be performed only by surgeons experienced in adrenal and oncological surgery aiming at a complete en bloc resection (including resection of oligo-metastatic disease). (iv) We suggest that all suspected ACC should be reviewed by an expert adrenal pathologist using the Weiss score and providing Ki67 index. (v) We suggest adjuvant mitotane treatment in patients after radical surgery that have a perceived high risk of recurrence (ENSAT stage III, or R1 resection, or Ki67 >10%). (vi) For advanced ACC not amenable to complete surgical resection, local therapeutic measures (e.g. radiation therapy, radiofrequency ablation, chemoembolization) are of particular value. However, we suggest against the routine use of adrenal surgery in case of widespread metastatic disease. In these patients, we recommend either mitotane monotherapy or mitotane, etoposide, doxorubicin and cisplatin depending on prognostic parameters. In selected patients with a good response, surgery may be subsequently considered. (vii) In patients with recurrent disease and a disease free interval of at least 12 months, in whom a complete resection/ablation seems feasible, we recommend surgery or alternatively other local therapies. Furthermore, we offer detailed recommendations about the management of mitotane treatment and other supportive therapies. Finally, we suggest directions for future research. PMID- 30299886 TI - MECHANISMS IN ENDOCRINOLOGY: Bone marrow adiposity and bone, a bad romance? AB - Bone marrow adipocytes (BMA-) constitute an original and heterogeneous fat depot whose development appears interlinked with bone status throughout life. The gradual replacement of the haematopoietic tissue by BMA arises in a well-ordered way during childhood and adolescence concomitantly to bone growth and continues at a slower rate throughout the adult life. Importantly, BM adiposity quantity is found well associated with bone mineral density (BMD) loss at different skeletal sites in primary osteoporosis such as in ageing or menopause but also in secondary osteoporosis consecutive to anorexia nervosa. Since BMA and osteoblasts originate from a common mesenchymal stem cell, adipogenesis is considered as a competitive process that disrupts osteoblastogenesis. Besides, most factors secreted by bone and bone marrow cells (ligands and antagonists of the WNT/beta catenin pathway, BMP and others) reciprocally regulate the two processes. Hormones such as oestrogens, glucocorticoids, parathyroid and growth hormones that control bone remodelling also modulate the differentiation and the activity of BMA. Actually, BMA could also contribute to bone loss through the release of paracrine factors altering osteoblast and/or osteoclast formation and function. Based on clinical and fundamental studies, this review aims at presenting and discussing these current arguments that support but also challenge the involvement of BMA in the bone mass integrity. PMID- 30299887 TI - MECHANISMS OF ENDOCRINOLOGY: Endocrinology of opioids AB - The use of opioids has grown substantially over the past two decades reaching the dimensions of a global epidemic. These drugs have effects on multiple levels of the endocrine system through mechanisms which are still not fully elucidated, and awareness of their endocrine sequelae is vital for all specialists prescribing or managing patients on them. Hypogonadism is the most well-recognised consequence of opioid use (prevalence 21-86%) which, however, may remain undiagnosed with potential adverse outcomes for the patients. Although less frequent, cortisol deficiency can also be found. Furthermore, there is a negative impact on bone health (with reduced bone mineral density and increased fracture risk) and occasionally hyperprolactinaemia, whereas the clinical significance of alterations in other hormones remains to be clarified. Discontinuation or reduction of the opioid and, in cases of chronic pain, consideration of alternative therapies for pain relief are potential management options. Hormonal replacement, especially when the above measures are not practically feasible, needs to be considered. Further studies are needed to clearly establish the prevalence of hormonal abnormalities with various regimes, doses and routes of opioids and to address reliably the long-term benefits and risks of hormonal treatment in patients on opioids. Until evidence-based, safe and cost-effective clinical guidelines become available, periodical assessment of the gonadal and adrenal function (particularly when relevant clinical manifestations are present) and evaluation of the bone health status are advised. PMID- 30299889 TI - MANAGEMENT OF ENDOCRINE DISEASE: Critical review of the evidence underlying management of glucocorticoid-induced hyperglycaemia AB - Glucocorticoids are frequently prescribed to patients with a wide range of inflammatory and autoimmune diseases. The semi-synthetic glucocorticoid prednisolone is most commonly prescribed and in two main patterns. Prednisolone is prescribed short term at medium-high doses to treat an acute inflammatory illness or long term at lower doses to attenuate chronic inflammatory disease progression. In hospitalized patients with acute prednisolone-induced hyperglycaemia, there is a distinct circadian pattern of glucose elevation, which occurs predominantly in the afternoon and evening. As a morning dose of isophane insulin has a pharmacokinetic pattern that matches this pattern of glucose elevation, treatment comprising a basal dose of morning isophane insulin in combination with short-acting insulin boluses is generally recommended. However, evidence is lacking that isophane-based basal bolus insulin is more efficacious than other insulin regimens. In outpatients, low-dose prednisolone causes a small increase in post glucose-load glucose concentration but no change in overall glycaemic control as measured by glycosylated haemoglobin. If treatment is indicated, metformin has been shown to be effective and may attenuate other adverse effects of long-term prednisolone therapy. Further studies are necessary in order to identify factors underlying the variability in response to insulin therapy and clinical benefits of treatment in hospitalized patients with prednisolone-induced hyperglycaemia. In outpatients prescribed low-dose prednisolone, the cardiovascular risk associated with postprandial hyperglycaemia and efficacy of hypoglycaemic therapies should be evaluated in future randomized clinical trials. PMID- 30299888 TI - GENETICS IN ENDOCRINOLOGY: Approaches to molecular genetic diagnosis in the management of differences/disorders of sex development (DSD): position paper of EU COST Action BM 1303 'DSDnet' AB - The differential diagnosis of differences or disorders of sex development (DSD) belongs to the most complex fields in medicine. It requires a multidisciplinary team conducting a synoptic and complementary approach consisting of thorough clinical, hormonal and genetic workups. This position paper of EU COST (European Cooperation in Science and Technology) Action BM1303 'DSDnet' was written by leading experts in the field and focuses on current best practice in genetic diagnosis in DSD patients. Ascertainment of the karyotpye defines one of the three major diagnostic DSD subclasses and is therefore the mandatory initial step. Subsequently, further analyses comprise molecular studies of monogenic DSD causes or analysis of copy number variations (CNV) or both. Panels of candidate genes provide rapid and reliable results. Whole exome and genome sequencing (WES and WGS) represent valuable methodological developments that are currently in the transition from basic science to clinical routine service in the field of DSD. However, in addition to covering known DSD candidate genes, WES and WGS help to identify novel genetic causes for DSD. Diagnostic interpretation must be performed with utmost caution and needs careful scientific validation in each DSD case. PMID- 30299890 TI - Prognostic relevance of proliferation-related miRNAs in pancreatic neuroendocrine neoplasms AB - Objective: Pancreatic neuroendocrine neoplasms (PanNENs) are rare tumors arising from the endocrine pancreas; however, their prognosis differs significantly upon their proliferative state, which is characterized by histopathological grading. MiRNAs are small, noncoding RNAs posttranscriptionally regulating gene expression. Our aim was to identify miRNAs with altered expression upon proliferation which can be used as prognostic biomarkers in PanNENs. Methods: MiRNA expression profiles of 40 PanNENs were downloaded from Gene Expression Omnibus and were reanalyzed upon tumor grades (discovery cohort). Results of the reanalysis were confirmed by qRT-PCR analysis of five miRNAs on an independent validation cohort of 63 primary PanNEN samples. Cox proportional hazards survival regression models were fit for both univariate and multivariate analysis to determine the miRNAs' effect on progression-free and overall survival. Results: Nineteen miRNAs displayed differential expression between tumor grades. The altered expression of three out of five chosen miRNAs was successfully validated; hsa-miR-21, hsa-miR-10a and hsa-miR-106b were upregulated in more proliferative PanNENs compared to Grade 1 tumors. In univariate analysis, higher expression of tissue hsa-miR-21, hsa-miR-10a and hsa-miR-106b of primary PanNENs predicted worse progression-free and overall survival; however, multivariate analysis only confirmed the expression of hsa-miR-21 as an independent prognostic factor. Conclusions: The expression of hsa-miR-106b, hsa-miR-10a and especially hsa-miR 21 has prognostic relevance regarding progression-free and overall survival in patients with PanNENs. PMID- 30299891 TI - Comorbidities in patients with non-functioning pituitary adenoma: influence of long-term growth hormone replacement AB - Background: Patients with hypopituitarism have an increased mortality. The aim of this study was to investigate comorbidities including cerebral infarction, type 2 diabetes mellitus (T2DM) and malignant tumors in patients with non-functioning pituitary adenomas (NFPA) with and without growth hormone replacement therapy (GHRT). Methods: Observational cohort study in patients with NFPA within the western region of Sweden. Subjects were identified through the National Patient Registry and followed between 1987 and 2014. Patient records were reviewed and standardized incidence ratios (SIRs) with 95% CIs for comorbidities were calculated. Results: In total, 426 patients were included, 206 with GHRT and 219 without. Median (range) follow-up time for patients with and without GHRT was 12.2 (0-24) and 8.2 (0-27) years, respectively. Mean +/- s.d. BMI was 28.5 +/- 4.5 and 26.5 +/- 4.4 for patients with and without GHRT, respectively (P < 0.001). Incidence of cerebral infarction was increased (SIR: 1.39; 95% CI: 1.03 1.84; P = 0.032), with no difference between patients with and without GHRT. SIR for T2DM in patients not receiving GHRT was increased (1.65; 1.06-2.46; P = 0.018), whereas the incidence in patients receiving GHRT was not (0.99; 0.55 1.63; P = 0.99). The incidence of malignant tumors was not increased, either in patients with or without GHRT. Conclusion: The incidence of cerebral infarction is increased in patients with NFPA irrespective of GHRT. Patients without GHRT had an increased risk of T2DM, whereas patients with GHRT had a normal incidence of T2DM, despite having higher BMI. Incidence of malignant tumors was not increased. Thus, long-term GHRT seems to be safe regarding risk of comorbidities. PMID- 30299893 TI - ? PMID- 30299892 TI - ?

We investigated the association between change in serum 25(OH)D and parallel change in depressive symptoms over time in Dutch older adults. Design: A population based, prospective study in two cohorts of older men and women from the Longitudinal Aging Study Amsterdam. Methods: Serum 25(OH)D concentrations were determined at two time points: in 1995/1996 and 13 years later in the older cohort (aged 65-88y, n = 173) and in 2002/2003 and 6 years later in the younger cohort (55-65 years, n = 450). At these time points, depressive symptoms were measured with the Center for Epidemiologic Studies Depression scale (CES-D). Associations were tested by multiple linear regression analyses. Results: During follow-up, serum 25(OH)D concentrations increased in 32.4% of the older cohort and in 69.8% of the younger cohort. In the older cohort, change in 25(OH)D was not associated with change in CES-D score. In the younger cohort, no associations were observed in participants with higher baseline 25(OH)D concentrations (>58.6 nmol/L), but in those with lower baseline 25(OH)D concentrations, an increase in 25(OH)D was associated with a decrease in CES-D score (adjusted B per 10 nmol/L 25(OH)D increase: -0.62 (95% CI: -1.17, -0.07)).

Diabetes and impaired kidney function are common side effects of immunosuppressive therapy. This study addresses glucometabolic parameters and kidney function during the first year. Methods: We examined 67 patients with functioning grafts (SPK n = 30, PTA n = 37) transplanted between September 2011 and November 2016 who underwent repeated oral glucose tolerance tests (OGTTs) 8 and 52 weeks after transplantation. Another 19 patients lost their graft the first year post transplant and 28 patients did not undergo repeated OGTTs and could not be studied. All patients received ATG induction therapy plus tacrolimus, mycophenolate and prednisolone. Glomerular filtration rate was measured before and 8 and 52 weeks after transplantation by serum clearance methods. Results: From week 8 to 52 after transplantation, mean fasting glucose decreased (SPK: 5.4 +/- 0.7 to 5.1 +/- 0.8 mmol/L, PTA: 5.4 +/- 0.6 to 5.2 +/- 0.7 mmol/L; both P < 0.05), and also 120-min post-OGTT glucose (SPK: 6.9 +/- 2.9 to 5.7 +/- 2.2 mmol/L; P = 0.07, PTA: 6.5 +/- 1.7 to 5.7 +/- 1.2 mmol/L; P < 0.05). Fasting C peptide levels also decreased (SPK: 1500 +/- 573 to 1078 +/- 357 pmol/L, PTA: 1210 +/- 487 to 1021 +/- 434 pmol/L, both P < 0.005). Measured GFR decreased from enlistment to 8 weeks post transplant in PTA patients (94 +/- 22 to 78 +/- 19 mL/min/1.73 m2; P < 0.005), but did not deteriorate from week 8 to week 52 (SPK: 55.0 +/- 15.1 vs 59.7 +/- 11.3 ml/min/1.73 m2; P = 0.19, PTA: 76 +/- 19 vs 77 +/- 19 mL/min/1.73 m2; P = 0.74). Conclusion: Glycemic control and kidney function remain preserved in recipients with functioning SPK and PTA grafts 1 year after transplantation. PMID- 30299898 TI - ? PMID- 30299900 TI - ?

Serum FGF1 has increased in type 2 diabetes mellitus adults and correlated with BMI. This study aimed to indicate conventional weight loss effects on FGF1 in obese children and adolescents. Materials and Methods: Clinical and metabolic parameters of 88 lean and obese individuals (ages 5-15 years) and 39 obese individuals followed with 6 months of lifestyle intervention were collected. Serum FGF1 levels were detected through enzyme-linked immunosorbent assays. Results: FGF1 levels were increased in obese individuals. Serum FGF1 levels were significantly correlated with BMI and waist circumferences (r = 0.377, P = 0.012; r = 0.301, P = 0.047, respectively). Multivariate stepwise linear regression analyses showed that FGF1 levels were significantly correlated with HbA1c and HOMA-IR (beta = 0.371, P = 0.008; beta = 0.323, P = 0.021, respectively). Weight loss (2.3 +/- 0.1 kg) was accompanied by a significant reduction of circulating FGF1 levels (7.2 +/- 0.4 pg/mL). Changes in FGF1 were significantly correlated with changes in fasting glucose, HOMA-IR and low-density lipoprotein cholesterol (beta = 0.277, P = 0.020; beta = 0.474, P < 0.001; beta = 0.320, P = 0.008, respectively). Conclusion: FGF1 levels were increased in obese individuals. Serum FGF1 levels were significantly correlated with BMI and waist circumferences (r = 0.377, P = 0.012; r = 0.301, P = 0.047, respectively).

PMID- 30299899 TI - Radiation exposure of adrenal vein sampling: a German Multicenter Study AB - Objective: Adrenal vein sampling (AVS) represents the current diagnostic standard for subtype differentiation in primary aldosteronism (PA). However, AVS has its drawbacks. It is invasive, expensive, requires an experienced interventional radiologist and comes with radiation exposure. However, exact radiation exposure of patients undergoing AVS has never been examined. Design and Methods: We retrospectively analyzed radiation exposure of 656 AVS performed between 1999 and 2017 at four university hospitals. The primary outcomes were dose area product (DAP) and fluoroscopy time (FT). Consecutively the effective dose (ED) was approximately calculated. Results: Median DAP was found to be 32.5 Gy*cm2 (0.3 3181) and FT 18 min (0.3-184). The calculated ED was 6.4 mSv (0.1-636). Remarkably, values between participating centers highly varied: Median DAP ranged from 16 to 147 Gy*cm2, FT from 16 to 27 min, and ED from 3.2 to 29 mSv. As main reason for this variation, differences regarding AVS protocols between centers could be identified, such as number of sampling locations, frames per second and the use of digital subtraction angiographies. Conclusions: This first systematic assessment of radiation exposure in AVS not only shows fairly high values for patients, but also states notable differences among the centers. Thus, we not only recommend taking into account the risk of radiation exposure, when referring patients to undergo AVS, but also to establish improved standard operating procedures to prevent unnecessary radiation exposure.

AB - Three new lanthanide-based metal-organic frameworks (Ln-MOFs), namely MOF-590, 591, and -592 constructed from a tetratopic linker, benzoimidephenanthroline tetracarboxylic acid (H4BIPA-TC), were synthesized under solvothermal conditions and fully characterized. All of the new MOFs exhibit three-dimensional frameworks, which adopt unprecedented topologies in MOF field. Gas adsorption measurements of MOF-591 and -592 revealed good adsorption of CO2 (low pressure, at room temperature) and moderate CO2 selectivity over N2 and CH4. Consequently, breakthrough experiments illustrated the separation of CO2 from binary mixture of CO2 and N2 with the use of MOF-592. Accordingly, MOF-592 revealed the selective CO2 capture effectively without any loss in performance after three cycles. Moreover, MOF-590, -591, and -592 showed to be catalytically active in the oxidative carboxylation of styrene and CO2 for a one-pot synthesis of styrene carbonate under mild conditions (1 atm CO2, 80 degrees C, and without solvent). Among the new materials, MOF-590 revealed a remarkable efficiency with exceptional conversion (96%), selectivity (95%), and yield (91%).

AB - Background: Computerized image analysis seems to represent a promising diagnostic possibility for thyroid tumors. Our aim was to evaluate the discriminatory diagnostic efficiency of computerized image analysis of cell nuclei from histological materials of follicular tumors. Methods: We studied paraffin embedded materials from 42 follicular adenomas (FA), 47 follicular variants of papillary carcinomas (FVPC) and 20 follicular carcinomas (FC) by the software ImageJ. Based on the nuclear morphometry and chromatin texture, the samples were classified as FA, FC or FVPC using the Classification and Regression Trees method. Results: We observed high diagnostic sensitivity and specificity rates (FVPC: 89.4% and 100%; FC: 95.0% and 92.1%; FA: 90.5 and 95.5%, respectively). When the tumors were compared by pairs (FC vs FA, FVPC vs FA), 100% of the cases were classified correctly. Conclusion: The computerized image analysis of nuclear features showed to be a useful diagnostic support tool for the histological differentiation between follicular adenomas, follicular variants of papillary carcinomas and follicular carcinomas. PMID- 30299918 TI - Dynamics of Architecturally Engineered All-Polymer Nanocomposites. AB - We present nanocomposite materials formed by using glassy star-shaped polymers as nanofillers and dispersing them in soft matrices. The resulting "architecturally engineered" polymer nanocomposites structurally reside between the linear homopolymer blends and the conventional polymer nanocomposites with inorganic fillers, inducing reinforcement, which can be as strong as that of solid nanoparticles, or softening depending on the compactness and concentration of the nanoparticles. Such behavior can be traced back to the dynamical features at the local segmental and the chain level, which we investigated using neutron scattering over a wide range of time and length scales in the glassy and melt states of the nanocomposites. The local and segmental dynamics as well as the degree of chain-chain entanglements are all modified by the star-shaped fillers. The presented approach to tuning the physical properties of all-polymer-based nanocomposites is readily adaptable to other polymer architectures with immediate applications in numerous areas including gas separation membranes, tissue engineering, drug delivery, and functional coatings. PMID- 30299919 TI - Thermal Percolation Threshold and Thermal Properties of Composites with High Loading of Graphene and Boron Nitride Fillers. AB - We investigated thermal properties of the epoxy-based composites with the high loading fraction-up to f ~ 45 vol %-of the randomly oriented electrically conductive graphene fillers and electrically insulating boron nitride fillers. It was found that both types of the composites revealed a distinctive thermal percolation threshold at the loading fraction fT > 20 vol %. The graphene loading required for achieving thermal percolation, fT, was substantially higher than the loading, fE, for electrical percolation. Graphene fillers outperformed boron nitride fillers in the thermal conductivity enhancement. It was established that thermal transport in composites with high filler loadings, f >= fT, is dominated by heat conduction via the network of percolating fillers. Unexpectedly, we determined that the thermal transport properties of the high loading composites were influenced strongly by the cross-plane thermal conductivity of the quasi-two dimensional fillers. The obtained results shed light on the debated mechanism of the thermal percolation, and facilitate the development of the next generation of the efficient thermal interface materials for electronic applications. PMID- 30299921 TI - Polyanthraquinone-Triazine-A Promising Anode Material for High-Energy Lithium-Ion Batteries. AB - A novel covalent organic framework polymer material that bears conjugated anthraquinone and triazine units in its skeleton has been prepared via a facile one-pot condensation reaction and employed as an anode material for Li-ion batteries. The conjugated units consist of C?N groups, C?O groups, and benzene groups, which enable a 17-electron redox reaction with Li per repeating unit and bring a theoretical specific capacity of 1450 mA h g-1. The polymer also shows a large specific surface area and a hierarchically porous structure to trigger interfacial Li storage and contribute to an additional capacity. The highly conductive conjugated polymer skeleton enables fast electron transport to facilitate the Li storage. In this way, the polymer electrode shows a large specific capacity and favorable cycling and rate performance, making it an appealing anode choice for the next-generation high-energy batteries. PMID- 30299922 TI - Localization of Protein Complex Bound Ligands by Surface-Induced Dissociation High-Resolution Mass Spectrometry. AB - Surface-induced dissociation (SID) is a powerful means of deciphering protein complex quaternary structures due to its capability of yielding dissociation products that reflect the native structures of protein complexes in solution. Here we explore the suitability of SID to locate the ligand binding sites in protein complexes. We studied C-reactive protein (CRP) pentamer, which contains a ligand binding site within each subunit, and cholera toxin B (CTB) pentamer, which contains a ligand binding site between each adjacent subunit. SID dissects ligand-bound CRP into subcomplexes with each subunit carrying predominantly one ligand. In contrast, SID of ligand-bound CTB results in the generation of subcomplexes with a ligand distribution reflective of two subunits contributing to each ligand binding site. SID thus has potential application in localizing sites of small ligand binding for multisubunit protein-ligand complexes. PMID- 30299920 TI - Manganese-Hydroxido Complexes Supported by a Urea/Phosphinic Amide Tripodal Ligand. AB - Hydrogen bonds (H-bonds) within the secondary coordination sphere are often invoked as essential noncovalent interactions that lead to productive chemistry in metalloproteins. Incorporating these types of effects within synthetic systems has proven a challenge in molecular design that often requires the use of rigid organic scaffolds to support H-bond donors or acceptors. We describe the preparation and characterization of a new hybrid tripodal ligand ([H2pout]3-) that contains two monodeprotonated urea groups and one phosphinic amide. The urea groups serve as H-bond donors, while the phosphinic amide group serves as a single H-bond acceptor. The [H2pout]3- ligand was utilized to stabilize a series of Mn-hydroxido complexes in which the oxidation state of the metal center ranges from 2+ to 4+. The molecular structure of the MnIII-OH complex demonstrates that three intramolecular H-bonds involving the hydroxido ligand are formed. Additional evidence for the formation of intramolecular H-bonds was provided by vibrational spectroscopy in which the energy of the O-H vibration supports its assignment as an H-bond donor. The stepwise oxidation of [MnIIH2pout(OH)]2- to its higher oxidized analogs was further substantiated by electrochemical measurements and results from electronic absorbance and electron paramagnetic resonance spectroscopies. Our findings illustrate the utility of controlling both the primary and secondary coordination spheres to achieve structurally similar Mn OH complexes with varying oxidation states. PMID- 30299923 TI - Transport Properties of Perfluorosulfonate Membranes Ion Exchanged with Cations. AB - In this work, the properties of univalent, that is, Li+, Na+, NH4+, and TEA+ form perfluorosulfonate (PFSA) membranes are studied and compared to the properties of H+ form materials. Properties of these polymer membranes including water uptake, density and conductivity, were investigated for membranes exposed to various water activity levels. The water uptake by the membranes decreased in the order H+ > Li+ > Na+ > NH4+ > TEA+, the same order as the hydration enthalpy (absolute values) of cations. Conductivity values did not strictly follow this order, indicating the importance of different factors besides the hydration level. The partial molar volume of water is derived from the density data as a function of water content for the various membrane forms. This provides further insight into the water, cation, and polymer interactions. Factors that contribute to the conductivity of these membranes include the size of cations, the electrostatic attraction between cations and sulfonate group, and the ion-dipole and hydrogen bonding interactions between cations and water. NH4+ transport is surprisingly high given the low water uptake in NH4+ form membranes. We attribute this to the ability of this ion to develop hydrogen bonded structures that helps to overcome electrostatic interactions with sulfonates. Pulsed-field gradient (PFG) nuclear magnetic resonance (NMR) was used to measure the diffusion coefficient of water in the membranes. FT-IR spectroscopy is employed to probe cation interactions with water and sulfonate sites in the polymer. Overall, the results reflect a competition between the strong electrostatic interaction between cation and sulfonate versus hydration and hydrogen bonding which vary with cation type. PMID- 30299924 TI - Visible Light Driven Organic Pollutants Degradation with Hydrothermally Carbonized Sewage Sludge and Oxalate Via Molecular Oxygen Activation. AB - Converting sewage sludge into functional environmental materials has become an attractive sewage sludge disposal route. In this study, we synthesize a sewage sludge-based material via a facile one-pot hydrothermal carbonization method and construct a visible light molecular oxygen activation system with hydrothermally carbonized sewage sludge (HTC-S) and oxalate to degrade various organic pollutants. It was found that iron species of HTC-S could chelate with oxalate to generate H2O2 via molecular oxygen activation under visible light, and also promote the H2O2 decomposition to produce *OH for the fast organic pollutants degradation. Taking sulfadimidine as the example, the apparent degradation rate of HTC-S/oxalate system was almost 5-20 times that of iron oxides/oxalate system. This outstanding degradation performance was attributed to the presence of iron containing clay minerals in HTC-S, as confirmed by X-ray diffraction measurements and Mossbauer spectrometry. In the oxalate solution, these iron-containing clay minerals could be excited more easily than common iron oxides under visible light, because the silicon species strongly interacted with iron species in HTC-S to form Fe-O-Si bond, which lowered the excitation energy of Fe-oxalate complex. This work provides an alternative sewage sludge conversion pathway and also sheds light on the environmental remediation applications of sewage sludge-based materials. PMID- 30299925 TI - Light-Tunable 1T-TaS2 Charge-Density-Wave Oscillators. AB - External stimuli-controlled phase transitions are essential for fundamental physics and design of functional devices. Charge density wave (CDW) is a metastable collective electronic phase featured by the periodic lattice distortion. Much attention has been attracted to study the external control of CDW phases. Although much work has been done in the electric-field-induced CDW transition, the study of the role of Joule heating in the phase transition is insufficient. Here, using the Raman spectroscopy, the electric-field-driven phase transition is in situ observed in the ultrathin 1T-TaS2. By quantitative evaluation of the Joule heating effect in the electric-field-induced CDW transition, it is shown that Joule heating plays a secondary role in the nearly commensurate (NC) to incommensurate (IC) CDW transition, while it dominants the IC-NC CDW transition, providing a better understanding of the electric field induced phase transition. More importantly, at room temperature, light illumination can modulate the CDW phase and thus tune the frequency of the ultrathin 1T-TaS2 oscillators. This light tunability of the CDW phase transition is promising for multifunctional device applications. PMID- 30299926 TI - High-Pressure Effect on the Optical Extinction of a Single Gold Nanoparticle. AB - When reducing the size of a material from bulk down to nanoscale, the enhanced surface-to-volume ratio and the presence of interfaces make the properties of nano-objects very sensitive not only to confinement effects but also to their local environment. In the optical domain, the latter dependence can be exploited to tune the plasmonic response of metal nanoparticles by controlling their surroundings, notably applying high pressures. To date, only a few optical absorption experiments have demonstrated this feasibility, on ensembles of metal nanoparticles in a diamond anvil cell. Here, we report a nontrivial combination between a spatial modulation spectroscopy microscope and an ultraflat diamond anvil cell, allowing us to quantitatively investigate the high-pressure optical extinction spectrum of an individual nano-object. A large tuning of the surface plasmon resonance of a gold nanobipyramid is experimentally demonstrated up to 10 GPa, in quantitative agreement with finite-element simulations and an analytical model disentangling the impact of metal and local environment dielectric modifications. High-pressure optical characterizations of single nanoparticles allow for the accurate investigation and modeling of size, strain, and environment effects on physical properties of nano-objects and also enable fine tuned applications in nanocomposites, nanoelectromechanical systems, or nanosensing devices. PMID- 30299927 TI - LiCrS2 and LiMnS2 Cathodes with Extraordinary Mixed Electron-Ion Conductivities and Favorable Interfacial Compatibilities with Sulfide Electrolyte. AB - Sulfide-type solid-state electrolytes for all-solid-state lithium ion batteries are capturing more and more attention. However, the electronegativity difference between the oxygen and the sulfur element makes sulfide-type solid-state electrolytes chemically incompatible with the conventional LiCoO2 cathode. In this work, we proposed a series of chalcopyrite-structured sulfide-type materials and systematically assessed their performances as the cathode materials in all solid-state lithium ion batteries by first-principle calculations. All the five metallic LiMS2 (M = Cr, Mn, Fe, Co, and Ni) materials are superionic conductors with extremely small lithium ion migration barriers in the range from 43 to 99 meV, much lower than most oxide- and even sulfide-type cathodes. Voltage and volume calculations indicate that only LiCrS2 and LiMnS2 cathodes are structurally stable during cycling with the stable voltage plateaus at ~3 V, much higher than that of the P3m1-LiTiS2 cathode. For the first time, we studied the interfacial lithium transport resistance from a new perspective of charge transfer and redistribution at the electrode/solid-state electrolyte interface. LiCrS2 and LiMnS2 cathodes exhibit favorable interfacial compatibilities with Li3PS4 electrolyte. Our investigations demonstrate that the metallic LiCrS2 and LiMnS2 superionic conductors would possess excellent rate capability, high energy density, good structural stability during cycling, and favorable interfacial compatibility with Li3PS4 electrolyte in all-solid-state lithium ion batteries. PMID- 30299928 TI - Toward Condensation-Resistant Omniphobic Surfaces. AB - Omniphobic surfaces based on reentrant surface structures repel all liquids, regardless of the surface material, without requiring low-surface-energy coatings. Although omniphobic surfaces have been designed and demonstrated, they can fail during condensation, a phenomenon ubiquitous in both nature and industrial applications. Specifically, as condensate nucleates within the reentrant geometry, omniphobicity is destroyed. Here, we show a nanostructured surface that can repel liquids even during condensation. This surface consists of isolated reentrant cavities with a pitch on the order of 100 nm to prevent droplets from nucleating and spreading within all structures. We developed a model to guide surface design and subsequently fabricated and tested these surfaces with various liquids. We demonstrated repellency to 10 degrees C below the dew point and showed durability over 3 weeks. This work provides important insights for achieving robust, omniphobic surfaces.

AB - A chiral ionic liquid (CIL) moiety of a l-pyrrolidin-2-ylimidazole-decorated homochiral UiO-68-type metal-organic framework, UiO-68-CIL (1), was successfully prepared by the combination of a new premodified chiral CIL ligand (H2L-CIL) and ZrCl4 via a solvothermal method. The TiO2-loaded TiO2@UiO-68-CIL (2) was prepared by impregnating 1 in a toluene solution of Ti(OPri)4 and sequential in situ hydrolysis. The obtained 2 can be a bifunctional asymmetric heterogeneous catalyst to successfully promote the one-pot Morita-Baylis-Hillman reaction starting from aromatic alcohols in a tandem way. PMID- 30299929 TI - Liquid Chromatography-Tandem Mass Spectrometry Approach for Determining Glycosidic Linkages. AB - The structural analysis of carbohydrates remains challenging mainly due to the lack of rapid analytical methods able to determine and quantitate glycosidic linkages between the diverse monosaccharides found in natural oligosaccharides and polysaccharides. In this research, we present the first liquid chromatography tandem mass spectrometry (LC-MS/MS)-based method for the rapid and simultaneous relative quantitation of glycosidic linkages for oligosaccharide and polysaccharide characterization. The method developed employs ultrahigh performance liquid chromatography coupled with triple quadrupole mass spectrometry (UHPLC/QqQ-MS) analysis performed in multiple reaction monitoring (MRM) mode. A library of 22 glycosidic linkages was built using commercial oligosaccharide standards. Permethylation and hydrolysis conditions along with LC MS/MS parameters were optimized resulting in a workflow requiring only 50 MUg of substrate for the analysis. Samples were homogenized, permethylated, hydrolyzed, and then derivatized with 1-phenyl-3-methyl-5-pyrazolone (PMP) prior to analysis by UHPLC/MRM-MS. Separation by C18 reversed-phase UHPLC along with the simultaneous monitoring of derivatized terminal, linear, bisecting, and trisecting monosaccharide linkages by mass spectrometry is achieved within a 15 min run time. Reproducibility, efficacy, and robustness of the method was demonstrated with galactan ( Lupin) and polysaccharides within food such as whole carrots. The speed and specificity of the method enables its application toward the rapid glycosidic linkage analysis of oligosaccharides and polysaccharides. PMID- 30299931 TI - Effect of Interface Structure on the Mechanical Properties of Graphene Nanosheets Reinforced Copper Matrix Composites. AB - Currently, seldom studies have paid close attention to the impact of the defects and oxygen-containing functional groups on the surface of the graphene for composite applications. In this work, two typical graphene materials, namely graphene nanosheets synthesized by an in situ catalytic reaction and reduced graphene oxide (RGO), were adopted to fabricate reinforced copper matrix composites by spark plasma sintering. A harmful transitional interfacial layer made up of Cu/CuOx/amorphous carbon/RGO, resulted from interfacial reaction between Cu and RGO, were observed in the RGO/Cu composite. In contrast, the in situ synthesized graphene with fewer defect and lower oxygen level can realize clean graphene-Cu interface with Cu-O-C bonding and thus lead to much improved interface bonding and superior yield strength and tensile ductility. These results imply that the in situ synthesized graphene is more favorable for achievement of robust interfacial bonding for enhancing the mechanical properties of the graphene-Cu composites.

PMID- 30299933 TI - Large-Area Preparation of Robust and Transparent Superomniphobic Polymer Films. AB - Transparent superamphiphobic surfaces that repel various liquids have many important applications, but there are critical challenges in their fabrication, such as expensive or complicated fabrication methods, contradictions between the rough surface for superamphiphobicity and smooth surface for transparency, large area fabrication, etc. Herein, we report a simple and effective strategy for large-scale fabrication of robust, transparent, and superomniphobic polymer films by combined unidirectional rubbing and heating-assisted assembly technology. The obtained polymer films display two kinds of special structures of monolayer ordered re-entrant geometries with either hexagonally triangular protrusions or with hexagonally rectangular micropillars, depending upon the sphere diameters of silica templates, and demonstrate excellent repellence to water and low-surface tension liquids, as well as high transparency. PMID- 30299934 TI - Design for Brighter Photon Upconversion Emissions via Energy Level Overlap of Lanthanide Ions. AB - The perfect energy level overlap of 2H11/2, 4S3/2, and 4F9/2 in Er3+ ions with those of 5F3, 5F4/5S2, and 5F5 in adjacently codoped Ho3+ ions allows efficient interenergy transfer. Therefore, in addition to routine activators, Er3+ or Ho3+ can further act as sensitizers to transfer the upconverted energy to nearby Ho3+ or Er3+, resulting in enhanced upconversion luminescence due to the emission overlap. Proper codoping of Er3+/Ho3+ or Ho3+/Er3+ obviously elevates the maximum doping concentration (thus producing additional upconverted photons) to a level higher than that causing luminescence quenching and significantly enhances upconversion emissions compared with those of singly Er3+ or Ho3+-doped host materials. Indeed, the so-far strongest red upconversion emission under 1532 nm excitation was obtained in LiYF4:Er/Ho@LiYF4 nanoparticles and Ho3+-sensitized Er3+ upconversion emissions excited by 1150 nm laser was simultaneously discovered. With great enhancement compared with that of singly Ho3+ doped counterparts, this work demonstrates the generality and rationality of our design strategy.

AB - Flexible fiber-shaped supercapacitors hold promising potential in the area of portable and wearable electronics. Unfortunately, their general application is hindered by the restricted energy densities due to low operating voltage and small specific surface area. Herein, an all-solid-state fiber-shaped asymmetric supercapacitor (FASC) possessing ultrahigh energy density is reported, in which the positive electrode was designed as Na-doped MnO2 nanosheets on carbon nanotube fibers (CNTFs) and the negative electrode as MoS2 nanosheet-coated CNTFs. Owing to the excellent properties of the designed electrodes, our FASCs exhibit a large operating potential window (0-2.2 V), a remarkable specific capacitance (265.4 mF/cm2), as well as an ultrahigh energy density (178.4 MUWh/cm2). Moreover, the devices are of outstanding mechanical flexibility.

AB - Potassium ferrate [Fe(VI)] is a promising oxidant widely used in water treatment for the elimination of organic pollutants. In this work, the reaction kinetics, products, and mechanisms of the antimicrobial agent chlorophene (CP) undergoing Fe(VI) oxidation in aqueous solutions were investigated. CP is very readily degraded by Fe(VI), with the apparent second-order rate constant, k, being 423.2 M-1 s-1 at pH 8.0. A total of 22 oxidation products were identified using liquid chromatography-quadrupole time-of-flight-mass spectrometry , and their structures were further elucidated using tandem mass spectrometry. According to the extracted peak areas in mass spectra, the main reaction products were the coupling products (dimers, trimers, and tetramers) that formed via single electron coupling. Theoretical calculations demonstrated that hydrogen abstraction should easily occur at the hydroxyl group to produce reactive CP. radicals for subsequent polymerization. Cleavage of the C-C bridge bond, electrophilic substitution, hydroxylation, ring opening, and decarboxylation were also observed during the Fe(VI) oxidation process. In addition, the degradation of CP by Fe(VI) was also effective in real waters, which provides a basis for potential applications.

AB - Mortality and disabilities as outcomes of cardiovascular diseases are primarily related to blood clotting. Optimization of thrombolytic drugs is aimed at the prevention of side effects (in particular, bleeding) associated with a disbalance between coagulation and anticoagulation caused by systemically administered agents. Minimally invasive and efficient approaches to deliver the thrombolytic agent to the site of clot formation are needed. Herein, we report a novel nanocomposite prepared by heparin-mediated cross-linking of urokinase with magnetite nanoparticles (MNPs@uPA). We showed that heparin within the composition evoked no inhibitory effects on urokinase activity. Importantly, the magneto control further increased the thrombolytic efficacy of the composition. Using our nanocomposition, we demonstrated efficient lysis of experimental clots in vitro and in animal vessels followed by complete restoration of blood flow. No sustained toxicity or hemorrhagic complications were registered in rats and rabbits after single bolus i.v. injection of therapeutic doses of MNPs@uPA. We conclude that MNPs@uPA is a prototype of easy-to-prepare, inexpensive, biocompatible, and noninvasive thrombolytic nanomedicines potentially useful in the treatment of blood clotting.

PMID- 30299940 TI - beta-Cyclodextrin-Modified Magnetic Nanoparticles Immobilized on Sepharose Surface Provide an Effective Matrix for Protein Refolding. AB - In this article, we propose an impressive and facile strategy to improve protein refolding using solid phase artificial molecular chaperones consisting of the surface-functionalized magnetic nanoparticles. Specifically, monotosyl-beta cyclodextrin connected to the surface of 3-aminopropyltriethoxysilane (APES) modified magnetic nanoparticles is immobilized on the sepharose surface to promote interaction with exposed hydrophobic surfaces of partially folded (intermediates) and unfolded states of proteins. Their efficiencies were investigated by circular dichroism spectroscopy and photoluminescence spectroscopy of the protein. Although the mechanism of this method is based on principles of hydrophobic chromatography, this system is not only purging the native protein from inactive inclusion bodies but also improving the protein refolding process. We chose beta-cyclodextrin (beta-CD) considering multiple reports in the literature about its efficiency in protein refolding and its biocompatibility. To increase the surface area/volume ratio of the sepharose surface by nanoparticles, more beta-CD molecules are connected to the sepharose surface to make a better interaction with proteins. We suppose that proteins are isolated in the nanospace created by bound cyclodextrins on the resin surface so intermolecular interactions are reduced. The architecture of nanoparticles was characterized by Fourier transform infrared spectra, X-ray diffraction, scanning electron microscopy images, energy dispersive X-ray spectroscopy, nuclear magnetic resonance (1H NMR and 13C NMR), and dynamic light scattering.

AB - We report the development and the implementation of an exciton approach that allows ab initio nonadiabatic dynamics simulations of electronic excitation energy transfer in multichromophoric systems. For the dynamics, a trajectory based strategy is used within the surface hopping formulation. The approach features a consistent hybrid formulation that allows the construction of potential energy surfaces and gradients by combining quantum mechanics and molecular mechanics within an electrostatic embedding scheme. As an application, the study of a molecular dyad consisting of a covalently bound BODIPY moiety and a tetrathiophene group is presented using time-dependent density functional theory (TDDFT). The results obtained with the exciton model are compared to previously performed full TDDFT dynamics of the same system. Our results show excellent agreement with the full TDDFT results, indicating that the couplings that lead to excitation energy transfer (EET) are dominated by Coulomb interaction terms and that charge-transfer states are not necessary to properly describe the nonadiabatic dynamics of the system. The exciton model also reveals ultrafast coherent oscillations of the excitation between the two units in the dyad, which occur during the first 50 fs.

PMID- 30299943 TI - Investigation of Physiological Properties of Transglycosylated Stevia with Cationic Surfactant and Its Application To Enhance the Solubility of Rebamipide. AB - The poor water solubility of rebamipide was enhanced by the mixed micelles of transglycosylated stevia (Stevia-G) and trimethylammonium chloride with varying carbon chain length (C nTAC, n = 14, 16, and 18). Fluorometry, isothermal titration calorimetry (ITC) and dynamic light scattering techniques examined the aggregation properties of Stevia-G and C nTAC. Synergism was found between Stevia G and C nTAC using the approaches of Clint and Rubingh. The negative interaction parameter (average betam = -4.17, -5.47, and -7.07) and excess free energy (average DeltaG degrees ex = -2.47, -3.06, and -3.88 kJ mol-1) increased with increasing chain length of C nTAC. The negative B1 values by the Maeda approach suggested that chain-chain interactions contribute to the formation of a mixed micelle. The solubilization of rebamipide in the mixed micelle was evaluated in the term of the molar solubilization ratio (MSR) and partition coefficient ( Km). The Km from the Stevia-G/C16TAC system was highest at a low mole fraction of C nTAC (0.2-0.6). In conclusion, the solubilization of rebamipide was more favorable between Stevia-G and C16TAC, although the stability of the mixed micelle was enhanced by an increase in hydrophobicity of the longer chain lengths used in C nTAC.

AB - The protein crystallization process requires screening of a large number of conditions using a large quantity of high-purity protein, which makes crystal structure analysis difficult. Thus, the development of easy and versatile protein crystallization techniques is both extremely desirable and highly challenging. Here I demonstrate the crystallization and structure determination of ubiquitin by genetic fusion to the highly porous honeycomb lattice of R1EN. I successfully crystallized and collected X-ray data from three R1EN-ubiquitin constructs with various linker lengths under the same conditions as the original R1EN. The crystals diffracted to 1.7-2.4 A resolution, and the ubiquitin structures were determined with results almost identical to the previously published structure. Moreover, the ubiquitin structure could be solved by molecular replacement using R1EN alone. This method may reduce the effort required for crystallization screening and is applicable to de novo protein structure determination.

AB - We report quantum-mechanical and semiclassical WKB calculations for energies and wave functions of high-lying 2Sigma states of H2+ in atomic units. The high-lying states we present lie in an unexplored regime, corresponding asymptotically to H ( n <= 146) plus a proton, with R <= 120 000 a0. We compare quantum-mechanical energies, spectroscopic constants, dipole matrix elements, and phases with semiclassical results and demonstrate a high level of agreement. Our quantum mechanical phases were determined by using Milne's phase-amplitude procedure. We compare our semiclassical energies for low-lying states with those of other researchers.

AB - Avermectin (AVM) as a nonsystemic pesticide possesses a low effective utilization rate. Studies of the multifunctional pesticide delivery system for improving biological activity are developing prosperously. In this study, multifunctional avermectin/polysuccinimide with glycine methyl ester nanoparticles (AVM-PGA) were prepared by the self-assembly process. The AVM loading capacity was up to 23.7%. After 24 h of UV irradiation, there was still about 70% of AVM remaining in PGA42 nanocarriers, as opposed to less than 5% of the free-form AVM. The rising ambient pH promoted the release of AVM using an in vitro releasing test, revealing a favorable pH-responsively controlled-release property. The mortality rate of Plutella xylostella with 2.5 MUg/mL of AVM content of AVM-PGA42 was 96.3% after 48 h, while that of free AVM was only 51.5%. In addition, the AVM could be detected in stems and all leaves treated with AVM-PGA42 nanoparticles, whereas rare AVM was detected only in treated leaves for the free-form AVM, which achieved the transportation of nanocarriers carrying AVM in rice for the first time. Furthermore, the PGA nanoparticles performed a good growth promoting effect on rice. These results show that the AVM-PGA42 nanopesticides have a great potential application prospect to control the pest and improve the drug utilization efficiency on agriculture. PMID- 30299947 TI - Sr2FeIrO4: Square-Planar Ir(II) in an Extended Oxide. AB - Topochemical reduction of the double-perovskite oxide Sr2FeIrO6 under dilute hydrogen leads to the formation of Sr2FeIrO4. This phase consists of ordered infinite sheets of apex-linked Fe2+O4 and Ir2+O4 squares stacked with Sr2+ cations and is the first report of Ir2+ in an extended oxide phase. Plane-wave density functional theory calculations indicate high-spin Fe2+ (d6, S = 2) and low-spin Ir2+ (d7, S = 1/2) configurations for the metals and confirm that both ions have a doubly occupied d z2 orbital, a configuration that is emerging as a consistent feature of all layered oxide phases of this type. The stability and double occupation of d z2 in the Ir2+ ions invites a somewhat unexpected analogy to the extensively studied Ir4+ ion as both ions share a common near-degenerate (d xy/ xz/ yz)5 valence configuration. On cooling below 115 K, Sr2FeIrO4 enters a magnetically ordered state in which the Ir and Fe sublattices adopt type II antiferromagnetically coupled networks which interpenetrate each other, leading to frustration in the nearest-neighbor Fe-O-Ir couplings, half of which are ferromagnetic and half antiferromagnetic. The spin frustration drives a symmetry lowering structural distortion in which the four equivalent Ir-O and Fe-O distances of the tetragonal I4/ mmm lattice split into two mutually trans pairs in a lattice with monoclinic I112/ m symmetry. This strong magneto-lattice coupling arises from the novel local electronic configurations of the Fe2+ and Ir2+ cations and their cation-ordered arrangement in a distorted perovskite lattice. PMID- 30299948 TI - Accuracy of Coupled Cluster Excited State Potential Energy Surfaces. AB - The validation of the quality of the description of excited electronic states is of special importance in quantum chemistry as the general reliability of ab initio methods shows a much larger variation for these states than for the ground state. In this study, we investigate the quality of excited state energy gradients and potential energy surfaces on selected systems, as provided by the single reference coupled cluster variants CC2, CCSD, CCSD(T)(a)*, and CC3. Gradients and surface plots that follow the Franck-Condon forces are compared to the respective CCSDT reference values, thereby establishing a useful strategy for judging each variant's accuracy. The results reveal serious flaws of lower order methods - in particular, CC2 - in several situations where they otherwise give accurate vertical excitation energies, as well as excellent accuracy and consistency of the recently proposed CCSD(T)(a)* method. PMID- 30299950 TI - Lessons from the Spin-Polarization/Spin-Contamination Dilemma of Transition-Metal Hyperfine Couplings for the Construction of Exchange-Correlation Functionals. AB - Hyperfine couplings (HFCs) of open-shell transition-metal centers are known to often depend crucially on core-shell spin polarization (CSSP). The latter is typically underestimated by semilocal density functionals, while admixture of exact exchange (EXX) in (global) hybrid functionals enhances CSSP. Unfortunately, a metal-ligand antibonding character of one or more of the singly occupied molecular orbitals of the complex will cause substantial valence-shell spin polarization (VSSP), which for global hybrids with higher EXX admixtures may lead to substantial spin contamination, thereby deteriorating the overall electronic structure and the dipolar couplings. In view of this known dilemma, we use a subset of 3d complexes from an earlier study (M. Munzarova, M. Kaupp J. Phys. Chem. A 1999, 103, 9966-9983) to examine systematically a wide range of exchange correlation functionals for metal HFCs, including highly parametrized (meta )GGAs, global, and range-separated hybrid functionals not yet available in earlier studies, as well as for the first time local hybrids with real-space position-dependent EXX admixture. Both CSSP and VSSP have been carefully analyzed in terms of their orbital contributions, both for cases dominated only by CSSP and for systems influenced crucially by VSSP and spin contamination. While some more parametrized meta-GGA functionals (tau-HCTH, VSXC, partially M06-L) provide surprisingly realistic CSSP, some others (MN12-L, MN15-L) and some global hybrids (M05, M06, partly MN15) exhibit dramatic shortcomings in describing the CSSP contributions. Local hybrid functionals provide a promising way of enhancing CSSP by high EXX admixture in the core region while avoiding excessive VSSP and thus spin contamination. These analyses provide important insights that may help to construct improved functionals for HFCs and related properties (e.g., contact NMR shifts). PMID- 30299949 TI - Electronically Excited Solute Described by RISM Approach Coupled with Multireference Perturbation Theory: Vertical Excitation Energies of Bioimaging Probes. AB - For theoretically studying molecules with fluorescence in the near-infrared region, high-accuracy determination of state energy level is required for meaningful analyses since the spectra of interest are of very narrow energy range. In particular, these molecules are in many cases handled in solution; therefore, consideration of the solvation effect is essential upon calculation together with the electronic structure of the excited state. Earlier studies showed that they cannot be described with conventional methods such as PCM-TD DFT, yielding results far from experimental data. Here, we have developed a new method by combining a solvation theory based on statistical mechanics (RISM) and a multireference perturbation theory (CASPT2) with the extension of the density matrix renormalization group reference states for calculating the photochemical properties of near-infrared molecules and have obtained higher-accuracy prediction. PMID- 30299951 TI - Linking Molybdenum-Sulfur Clusters for Electrocatalytic Hydrogen Evolution. AB - Controlling the spatial arrangement of molecular catalysts on electrodes is critical to developing an optimal electrocatalyst. Mo-S clusters have shown great promise in catalyzing hydrogen evolution for the generation of carbon-free fuel from water. Here we report a synthetic approach to organize these molecular clusters into ordered dimers, cages, and chains through the use of organic linkers, as solved by single-crystal X-ray diffraction. We find that the linkage through the coordination bond between thiolate and Mo3S7 leads to (1) a 40-fold enhancement in turnover frequency compared with the unlinked cluster and (2) the periodic arrangement of clusters on the electrode with control over their distance, orientation, and density, thus enabling hydrogen evolution at high catalyst loading. The materials developed here require an overpotential of only 89 mV to achieve a current density of 10 mA cm-2, outperforming other Mo-S catalysts (both molecular and solid-state). PMID- 30299952 TI - Insight into the Solvation Structure of Tetraglyme-Based Electrolytes via First Principles Molecular Dynamics Simulation. AB - Glyme-lithium salt equimolar mixtures, as solvate ionic liquid electrolytes for rechargeable lithium secondary batteries, are of great interest, due to the desirable properties such as high oxidative stability, low vapor pressure, and nonflammability. However, the fundamental understanding of the solvation shell structure in glyme electrolytes has not been clearly established. Herein, we employ first-principles molecular dynamics (FPMD) simulation to study the lithium bis(trifluoromethylsulfonyl)-amide (LiTFSA) and tetraglyme (G4) electrolyte system. For the case of equimolar ratio, a positive correlation between the total coordination number of Li+ ions and the phase stability is clearly established. At the ground state of equimolar LiTFSA-G4 electrolyte, most of the Li+ ions are coordinated to four O atoms of a curled G4 molecule and one O atom of a TFSA- anion, equivalent to the second most stable contact ion pair in gas-phase cluster calculations. By contrast, Li+ ions prefer to be coordinated by two G4 molecules and not in direct contact with TFSA- anions at a low concentration of Li salt. The significantly increased probability of pairing between the Li-G4 complexes and TFSA- anions at the equimolar ratio could be highly relevant to its ionic liquid-like properties. PMID- 30299953 TI - The Nonlocal Kernel in van der Waals Density Functionals as an Additive Correction: An Extensive Analysis with Special Emphasis on the B97M-V and omegaB97M-V Approaches. AB - The development of van der Waals density functional approximations (vdW-DFAs) has gained considerable interest over the past decade. While in a strictest sense, energy calculations with vdW-DFAs should be carried out fully self-consistently, we demonstrate conclusively for a total of 11 methods that such a strategy only increases the computational time effort without having any significant effect on energetic properties, electron densities, or orbital-energy differences. The strategy to apply a nonlocal vdW-DFA kernel as an additive correction to a fully converged conventional DFA result is therefore justified and more efficient. As part of our study, we utilize the extensive GMTKN55 database for general main group thermochemistry, kinetics, and noncovalent interactions [ Phys. Chem. Chem. Phys. 2017, 19, 32184], which allows us to analyze the very promising B97M-V [ J. Chem. Phys. 2015, 142, 074111] and omegaB97M-V [ J. Chem. Phys. 2016, 144, 214110] DFAs. We also present new DFT-D3(BJ) based counterparts of these two methods and of omegaB97X-V [ J. Chem. Theory Comput 2013, 9, 263], which are faster variants with similar accuracy. Our study concludes with updated recommendations for the general method user, based on our current overview of 325 dispersion-corrected and -uncorrected DFA variants analyzed for GMTKN55. vdW-DFAs are the best representatives of the three highest rungs of Jacob's Ladder, namely, B97M-V, omegaB97M-V, and DSD-PBEP86-NL.

AB - Advancing beyond Li-ion batteries requires translating the beneficial characteristics of Li+ electrodes to attractive, yet incipient, candidates such as those based on K+ intercalation. Here, we use ultrathin few-layer graphene (FLG) electrodes as a model interface to show a dramatic enhancement of K+ intercalation performance through a simple conditioning of the solid-electrolyte interphase (SEI) in a Li+ containing electrolyte. Unlike the substantial plating occurring in K+ containing electrolytes, we found that a Li+ based SEI enabled efficient K+ intercalation with discrete staging-type phase transitions observed via cyclic voltammetry at scan rates up to 100 mVs-1 and confirmed as ion intercalation processes through in situ Raman spectroscopy. The resulting interface yielded fast charge-discharge rates up to ~360C (1C is fully discharge in 1 h) and remarkable long-term cycling stability at 10C for 1000 cycles. This SEI promoted the transport of K+ as verified via mass spectrometric depth profiling. This work introduces a convenient strategy for improving the performance of ion intercalation electrodes toward a practical K-ion battery and FLG electrodes as a powerful analytical platform for evaluating fundamental aspects of ion intercalation. PMID- 30299955 TI - Major G-Quadruplex Form of HIV-1 LTR Reveals a (3 + 1) Folding Topology Containing a Stem-Loop. AB - Nucleic acids can form noncanonical four-stranded structures called G quadruplexes. G-quadruplex-forming sequences are found in several genomes including human and viruses. Previous studies showed that the G-rich sequence located in the U3 promoter region of the HIV-1 long terminal repeat (LTR) folds into a set of dynamically interchangeable G-quadruplex structures. G-quadruplexes formed in the LTR could act as silencer elements to regulate viral transcription. Stabilization of LTR G-quadruplexes by G-quadruplex-specific ligands resulted in decreased viral production, suggesting the possibility of targeting viral G quadruplex structures for antiviral purposes. Among all the G-quadruplexes formed in the LTR sequence, LTR-III was shown to be the major G-quadruplex conformation in vitro. Here we report the NMR structure of LTR-III in K+ solution, revealing the formation of a unique quadruplex-duplex hybrid consisting of a three-layer (3 + 1) G-quadruplex scaffold, a 12-nt diagonal loop containing a conserved duplex stem, a 3-nt lateral loop, a 1-nt propeller loop, and a V-shaped loop. Our structure showed several distinct features including a quadruplex-duplex junction, representing an attractive motif for drug targeting. The structure solved in this study may be used as a promising target to selectively impair the viral cycle.

AB - The queens of social insects differ from sterile colony members in many aspects of their physiology. Besides adaptations linked with their specialization for reproduction and extended lifespan, the queens also invest in the maintenance of their reproductive dominance by producing exocrine chemicals signaling their presence to the nestmates. The knowledge of the chemistry of queen-specific cues in termites is scarce. In addition to the contact recognition based on cuticular hydrocarbons, long-range signals mediated by volatiles are expected to participate in queen signaling, especially in populous colonies of higher termites (Termitidae). In queens of the higher termite Silvestritermes minutus (Syntermitinae), we have detected a previously undescribed volatile. It is present in important quantities on the body surface and in the headspace, ovaries, and body cavity. MS and GC-FTIR data analyses led us to propose the structure of the compound to be a macrolide 10-pentyl-3,4,5,8,9,10-hexahydro-2 H oxecin-2-one. We performed enantiodivergent syntheses of two possible enantiomers starting from enantiopure ( S)-glycidyl tosylate. The synthetic sequence involved macrolide-closing metathesis quenched with a ruthenium scavenging agent. The absolute and relative configuration of the compound was assigned to be (5 Z,9 S) tetradec-5-en-9-olide. Identification and preparation of the compound allow for investigation of its biological significance. PMID- 30299958 TI - Water-Soluble Leaving Group Enables Hydrophobic Functionalization of RNA.

AB - Certain types of nanoparticles, especially zinc oxide nanoparticles (ZnONPs), are widely reported to be capable of the inhibition of harmful bacteria, yeasts, and filamentous fungi. The unique physicochemical and biological properties of ZnONPs also make them attractive to the food industry for use as a promising antifungal agent. This Review thoroughly introduces the preparation methods and antifungal properties of ZnONPs and analyzes their possible antifungal mechanisms. The applicability of ZnONPs in food packaging and nutritional supplements and as an antimicrobial additive is also documented. Moreover, evaluations for biological safety of ZnONPs are objectively reviewed in this paper. The discussions addressed in this Review not only have theoretical significance but also are conducive to the development of food safety, nutrition, and human health. The summarized knowledge and future perspectives outlined here are expected to promote and guide new research toward developing and optimizing the application of ZnONPs as a novel class of antifungal agents to help improve food quality as well as food safety in the near future. PMID- 30299959 TI - Competing Intramolecular Hydrogen Bond Strengths and Intermolecular Interactions in the 4-Aminobutanol-Water Complex. AB - We seek to determine the effect of competing intermolecular hydrogen bonds from water on the preferred conformation of 4-aminobutanol (4AB) monomers stabilized by intramolecular hydrogen bonds. Toward this end, the rotational spectrum of the 4-aminobutanol-H2O complex was recorded using Fourier transform microwave spectroscopy and fit to the rotational, quadrupole coupling, and centrifugal distortion constants of the Watson S-reduction Hamiltonian. The experimental results are consistent with a 4AB-water complex that preserves the intramolecular hydrogen bond within the 4AB monomer and forms a single intermolecular bond with water acting as a donor. The experimental monomer structure agrees well with the lowest energy conformation calculated at the MP2/6-311++G(d,p) level of theory. Upon complex formation and the introduction of competing intermolecular bonds from water, only small changes in the OH...N intramolecular hydrogen bond and backbone torsional angles of the 4-aminobutanol monomer are observed. Similar small changes were observed for the shorter chain 3-aminopropanol amino alcohol monomer when complexed with water, in contrast to the 2-aminoethanol-H2O complex. In the latter, a large change in the backbone torsional angle and a breaking of the intramolecular hydrogen bond were observed. Thus, extending the methylene chain results in an increase in the strength of the intramolecular hydrogen bond in unbranched amino alcohols. PMID- 30299960 TI - Zinc-Induced Conformational Transitions in Human Islet Amyloid Polypeptide and Their Role in the Inhibition of Amyloidosis. AB - Type-2 diabetes mellitus (T2DM) is a disease hallmarked by improper homeostasis within the islets of Langerhans of the pancreas. The most critical species affected is insulin, which is produced by the beta-cells of the islets, but there are a number of other species copackaged and cosecreted within the insulin granules. This includes zinc, which exists in high (millimolar) concentrations within the beta-cells, and islet amyloid polypeptide (IAPP), which is an amyloid peptide thought to induce beta-cell apoptosis through self-association into toxic amyloid oligomers. Zinc is essential in the packaging of crystalline insulin within the vesicles but it can also bind and interact with IAPP. This implies a complex relationship between all three species and diabetes, particularly in the structure and function of toxic IAPP aggregates. Atypical (low or high) concentrations of zinc generally appear to correlate with increased hIAPP aggregation, whereas physiological zinc concentrations have an inhibitory effect. To better understand how zinc ions alter the monomer and oligomer structure of hIAPP in vitro, we employ a combination of ion mobility mass spectrometry and atomic force microscopy. We observe an increase in the extended beta-hairpin conformation of hIAPP when it is bound to zinc. With sufficiently low concentrations of zinc this could result in an association site for zinc-free hIAPP, promoting amyloid aggregation. At high zinc concentrations, we see the appearance of a secondary zinc association site whose coordination could account for the loss of inhibition at high zinc concentrations. Generally, it appears that zinc preferentially stabilizes the beta-hairpin conformation of hIAPP and the population of zinc-bound hIAPP in solution determines what effect this has on amyloid aggregation.

AB - Preventing ice formation during cryopreservation by vitrification has led to the successful storage and banking of numerous cellular- and tissue-based biomaterials. In their breakthrough work, Peter Mazur's group achieved over 90% survival by using a laser warming technique for 100 MUm mice oocytes that were cooled in 0.1 MUL droplets with 2.3 M CPA and extracellularly loaded India ink (laser absorber). Laser warming can provide rapid and uniform warming rates to "outrun" damaging ice crystal growth. Here we generalize Mazur's technique for microliter-sized droplets using laser nanowarming to rewarm millimeter-scale biomaterials when loaded extracellularly and/or intracellularly with biocompatible 1064 nm resonant gold nanoparticles. First, we show that droplets containing low-concentration cryoprotectants (such as 2 M propylene glycol +/- 1 M trehalose) can be rapidly cooled at rates up to 90 000 degrees C/min by plunging into liquid nitrogen to achieve either a visually transparent state (i.e., vitrified) or a cloudy with ice (i.e., nonvitrified) state. Both modeling and experiments were then used to characterize the laser nanowarming process for different laser energy (2-6 J), pulse length (1-20 ms), droplet volume (0.2-1.8 MUL), cryoprotectant (2-3 M), and gold concentration (0.77 * 1017-4.8 * 1017 nps/m3) values to assess physical and biological success. Physical success was achieved by finding conditions that minimize cloudiness and white spots within the droplets during cooling and warming as signs of damaging ice formation and ice crystallization, respectively. Biological success was achieved using human dermal fibroblasts to find conditions that achieve >=90% cell viability normalized to controls postwarming. Thus, physical and biological success can be achieved using this platform cryopreservation approach of rapid cooling and laser gold nanowarming in millimeter-scale systems.

AB - This work investigates the role of surface parameters such as the nanoscale roughness, topography, and skewness of smooth and rough Si surfaces in the shape of patterns left by evaporating colloidal droplets of spherical polystyrene particles. The droplet contact angle, colloidal deposition pattern, crack density, and rim growth velocities are experimentally evaluated for varying roughness. The contact angle and rim growth rate are found to be more for rough surfaces in comparison to smooth ones. Roughness also helps in reducing stress in the drying droplets, thereby impeding the process of crack formation as exemplified by the experimental results. The altered Derjaguin-Landau-Verwey Overbeek (DLVO) interactions emerging from the contribution of nanoscale roughness are theoretically evaluated for each differently rough substrate particle combination. The forces have been calculated by considering large- and small-scale roughness parameters of the experimental surfaces. The experimental findings have been duly corroborated by theoretical estimates. Finally, it is observed that the skewness of the surface and the small-scale asperity radius bear a correlation with the DLVO forces and subsequently with the ring deposit pattern. The present understanding of the influence of surface fluctuations on evaporative self-assembly would enable one to choose the right topographic surface for particular applications.

PMID- 30299964 TI - Intermolecular Voids in Lipid Bilayers in the Presence of Glycyrrhizic Acid. AB - It is known that glycyrrhizic acid (GA) promotes the enhancement of the activity of several medicines. This is attributed to the fact that GA increases the membrane permeability of small drug molecules. There is an opinion that GA facilitates the formation of additional large voids in the membrane, which enhance the passive diffusion of molecules across the membrane. In this work, we investigate how GA influences the intermolecular voids using the molecular dynamics simulation. We calculate the interstitial spheres (empty spheres inscribed between molecules) in model DPPC and DOPC bilayers, both pure and with the addition of cholesterol. It was observed that the addition of GA does not lead to the formation of new large interstitial spheres; i.e., new large voids do not appear. The distribution of empty volume inside the bilayers is also studied. We calculated the profiles of the empty volume fraction both from the middle plane of the bilayer and from its outer surface (from the lipid-water interface). This analysis has shown that the addition of GA does not cause the increase of the empty volume in the bilayer; moreover, there is a slight decrease in the bilayers with cholesterol. Thus, we have not found a confirmation of the simplest hypothesis that individual GA molecules induce pores in the membrane. PMID- 30299965 TI - Ranking in Vitro Dissolution of Inhaled Micronized Drug Powders including a Candidate Drug with Two Different Particle Sizes. AB - Pulmonary dissolution of poorly soluble drug substances (DSs) may limit the drug absorption rate and consequently influence clinical performance. Dissolution rate is thus an important quality attribute, and its influence on in vivo drug release must be characterized, understood, and controlled early in the development process. The aim of this study is to establish an in vitro dissolution method with the capability to capture therapeutically relevant differences in the dissolution rate between drug batches and drug compounds. A method was developed by which a biorelevant aerosol fraction was captured on a filter using a sedimentation technique in a modified Andersen cascade impactor to avoid particle agglomeration. Subsequently, the filters were transferred to a commercial Transwell system where dissolution in 3 mL of phosphate buffer at pH 6.8 with 0.5% sodium dodecyl sulfate (SDS) occurred at sink conditions. Dissolved DS was quantified over time using UPLC-UV. Dissolution data was obtained on a series of micronized and aerosolized lipophilic DSs, budesonide, fluticasone furoate (FF), fluticasone propionate (FP), and AZD5423. The latter is a lipophilic AstraZeneca development compound available in two different mass median diameters (MMD), 1.3 (AZD54231.3) and 3.1 MUm (AZD54233.1). Dissolution data were evaluated using a Weibull fit and expressed as t63, the time to dissolution of 63% of the initial dose. The following rank-order of t63 was obtained (mean t63 and MMD in brackets), budesonide (10 min, 2.1 MUm) = AZD54231.3 (10 min, 1.3 MUm) < AZD54233.1 (19 min, 3.1 MUm) < FP (38 min, 2.4 MUm) < FF (63 min, 2.5 MUm). The method could differentiate between different drug compounds with different solubility but similar particle size distribution, as well as between the same drug compound with different particle size distributions. Furthermore, a relation between the in vitro dissolution rate ( t63) and mean pulmonary absorption time in man (literature data) was observed, indicating clinical relevance. It is thus concluded, that the method may be useful for the characterization and ranking of DSs and drug products in early development, as well as being a potential tool for the control of dissolution as a potential quality attribute.

AB - The smart flexibility of phase transitions in liquid crystals (LCs) makes them suitable for various applications and is an important research field in contemporary science, engineering, and technology. Unlike most reports focused on bent-core LCs in the thermotropic situation, in our present study, we designed and synthesized a fully rigid bent-core molecule with the sulfonic acid group replacing conventional flexible chains. A rich variety of counterion-induced supramolecular LC phase behaviors have been systematically investigated. It was found that the smectic phase with nanosheets tends to transform to the hexagonal phase with nanofilaments when the protons of the sulfonic acid group are partially replaced by alkali metal ions. The experimental results show that the nanoaggregate and phase transition are controlled by the displacing ratio of alkali metal ions rather than the molecular concentration. Another interesting feature is that the achiral bent-core molecules self-assemble into columns by helical stacking and present macroscopic chirality, indicating that spontaneous chiral symmetry breaking occurs in the columnar phase. The fully rigid bent-core molecules reveal surprisingly hierarchical molecular self-assemblies with the smectic-to-hexagonal phase transition, which was not previously observed in supramolecular complexes. The findings will provide new possibilities for applications in LC-based photonic devices, biosystem switches, and supramolecular actuators.

The release profile was studied by monitoring the formation of lactone and direct trapping of GSSH with 1-fluoro-2,4-dinitrobenzene (DNFB). The donor was examined for its inhibitory effect toward glyceraldehyde 3-phosphate dehydrogenase (GAPDH). Under highly oxidative conditions, the donor also shows cytoprotective effects in H9c2 cardiomyocytes. PMID- 30299968 TI - Impact of Asphaltene Surface Energy on Stability of Asphaltene-Toluene System: A Parametric Study. AB - Asphaltene is a complex macromolecule whose abundance strongly affects the physical and interfacial properties of crude oil. Asphaltene molecules may precipitate during crude oil production/transportation, which may lead to plugging/clogging of wellbores, pipelines, and equipment. In this study, the solubility of asphaltene in toluene has been investigated by calculation of noncovalent interaction energies between asphaltenes in toluene medium. The results of this study revealed that the main interactions in the asphaltene toluene system are Lifshitz-van der Waals and Lewis acid-base interactions, whereas the electrostatic double layer is of lower comparative order of significance specifically at lower separation distances and lower zeta potentials. However, the repulsive electrostatic double-layer interactions may assist in stabilizing the asphaltene-toluene system based on the comparative values of Lifshitz-van der Waals, Lewis acid-base, and electrostatic double-layer interactions. This is the case especially at higher separation distances and/or higher temperatures where asphaltene particles have greater values of zeta potential. Furthermore, it is illustrated that when asphaltene has a lower electron-donor parameter, i.e., a lower basicity than toluene, then Lewis acid base interactions between asphaltenes in toluene are repulsive. This repulsive Lewis acid-base interaction may compensate for the attractive van der Waals interactions between asphaltene particles at low asphaltene basicity. Finally, the electron donor/acceptor component of the surface energy strongly determines the fate of asphaltene in crude oil colloidal system.

AB - The effect of surface coatings on the performance of antifouling activity under flow can be influenced by the flow/coating interactions. This study evaluates the effect of surface coatings on antifouling activity under different flows for the analyses of coating stability. This was done by exposing DOPA-PCB-300/dopamine coated polydimethylsiloxane (PDMS) to physiological shear stresses using a recirculation system which consisted of dual chamber acrylic flow cells, tygon tubing, flow probe and meter, and perfusion pumps. The effect of shear stress induced by phosphate buffered saline flow on coating stability was characterized with differences in fibrinogen adsorption between control (coated PDMS not loaded with shear stress) and coated samples loaded with various shear stresses. Fibrinogen adsorption data showed that relative adsorption on coated PDMS that were not exposed to shear (5.73% +/- 1.97%) was significantly lower than uncoated PDMS (100%, p < 0.001). Furthermore, this fouling level, although lower, was not significantly different from coated PDMS membranes that were exposed to 1 dyn/cm2 (9.55% +/- 0.09%, p = 0.23), 6 dyn/cm2 (15.92% +/- 10.88%, p = 0.14), and 10 dyn/cm2 (21.62% +/- 13.68%, p = 0.08). Our results show that DOPA-PCB 300/dopamine coatings are stable, with minimal erosion, under shear stresses tested. The techniques from this fundamental study may be used to determine the limits of stability of coatings in long-term experiments. PMID- 30299970 TI - Colloidal Stability of Apolar Nanoparticles: Role of Ligand Length. AB - Inorganic nanoparticle cores are often coated with organic ligands to render them dispersible in apolar solvents. However, the effect of the ligand shell on the colloidal stability of the overall hybrid particle is not fully understood. In particular, it is not known how the length of an apolar alkyl ligand chain affects the stability of a nanoparticle dispersion against agglomeration. Here, small-angle X-ray scattering and molecular dynamics simulations have been used to study the interactions between gold nanoparticles and between cadmium selenide nanoparticles passivated by alkanethiol ligands with 12-18 carbons in the solvent decane. We find that increasing the ligand length increases colloidal stability in the core-dominated regime but decreases it in the ligand-dominated regime. This unexpected inversion is connected to the transition from ligand-dominated to core-dominated agglomeration when the core diameter increases at constant ligand length. Our results provide a microscopic picture of the forces that determine the colloidal stability of apolar nanoparticles and explain why classical colloid theory fails.

AB - A palladium-catalyzed, amine-directed C(sp2)-H carbonylation of alpha,alpha disubstituted benzylamine under 1 atm of CO for the facile synthesis of sterically hindered benzolactam has been developed. The key to success is the use of 2,2,6,6-tetramethyl-1-piperidinyloxy as the crucial sole oxidant.

PMID- 30299974 TI - Effect of Lactation on Maternal Hypertension: A Systematic Review. AB - INTRODUCTION: Hypertension is relatively common in pregnancy, and pregnancy may unmask hypertension among women who are predisposed to it. Lactation may be a means through which to mitigate pregnancy-related vascular risk. The impact of lactation on maternal blood pressure, and the duration of any effect, remains unclear. This study aimed at systematically reviewing the literature evaluating the impact of lactation on the development of hypertension. MATERIALS AND METHODS: We searched PubMed, including EMBASE and MEDLINE, for studies that reported on the association between breastfeeding and maternal risk of hypertension that were published in a peer-reviewed source. The quality of the studies included was assessed by using the Newcastle-Ottawa Scale. RESULTS: Nineteen studies met all inclusion criteria for this review. Of the four studies with short-term follow-up, 50% showed a protective association. The fifteen studies with longer-term follow-up were stratified by outcome assessed. Sixty seven percent of the studies that evaluated for elevated blood pressure and 100% of the studies evaluating for an outcome of hypertension showed a protective association. The minimum duration of lactation associated with a benefit was 1 month. This association was demonstrated in follow-up periods as long as two to three decades. Studies that showed a protective association had overall higher quality ratings. DISCUSSION: Lactation is associated with a beneficial effect on maternal blood pressure that persists for decades. These results add to the growing body of literature demonstrating the protective association of lactation on maternal cardiovascular risk. Providers may incorporate the decreased risk of hypertension into their counseling on the maternal benefits of lactation. PMID- 30299975 TI - Executive Functioning Mediates Predictions of Youth Academic and Social Development from Parenting Behavior. AB - Using multiple mediation with bootstrapping, dimensions of executive functioning (i.e., inhibitory control, working memory, set shifting) were tested as mediators of predictions of academic and social outcomes from observed positive and negative parenting in 131 children followed prospectively into early adolescence. Inhibitory control and working memory mediated predictions of academic achievement, whereas inhibitory control meditated predictions of school competence from positive parenting. Additionally, working memory mediated predictions of negative social preference, but not social competence, from positive parenting. Executive functioning did not mediate predictions from negative parenting. The role of parenting in shaping youth outcomes through executive functioning is considered. PMID- 30299976 TI - In-Clinic Evaluation of the MiniMed 670G System "Suspend Before Low" Feature in Children with Type 1 Diabetes. AB - BACKGROUND: The Medtronic predictive low-glucose management (PLGM) algorithm automatically stops insulin delivery when sensor glucose (SG) is predicted to reach or fall below a preset low-glucose value within the next 30 min, and resumes delivery after hypoglycemia recovery. The present study evaluated the PLGM algorithm performance of the MiniMedTM 670G system SmartGuardTM "suspend before low" feature in children aged 7-13 years with type 1 diabetes (T1D). METHOD: Participants (N = 105, mean +/- standard deviation of 10.8 +/- 1.8 years) underwent an overnight in-clinic evaluation of the "suspend before low" feature with a preset low limit of 65 mg/dL. After exercise, frequent sample testing (FST) was conducted every 5 min if values were <70 mg/dL; every 15 min if 70-80 mg/dL; and every 30 min if >80 mg/dL. First-day performance of the GuardianTM Sensor 3 glucose sensor and continuous glucose monitoring system was also evaluated. RESULTS: Activation of the "suspend before low" feature occurred in 79 of the 105 participants, 79.7% (63/79) did not result in SG falling below 65 mg/dL. Mean glucose at activation was 102 +/- 19 mg/dL and the initial insulin suspension duration was 87.5 +/- 32.7 min. Four hours after insulin resumption, mean reference glucose was 130 +/- 42 mg/dL. Mean absolute relative difference between the FST reference glucose and SG values on the first day of sensor wear was 11.4%. For the 26 participants in whom the "suspend before low" feature did not activate, none involved a reference glucose value <=65 mg/dL, suggesting that the PLGM algorithm performed as intended. CONCLUSION: In children aged 7-13 years with T1D, the "suspend before low" feature of the MiniMed 670G system demonstrated a hypoglycemia prevention rate of nearly 80% after exercise and did not involve rebound hyperglycemia. There were no events of severe hypoglycemia during the evaluation. PMID- 30299977 TI - Sexual Distress Mediates the Associations Between Sexual Contingent Self-Worth and Well-Being in Women With Genitopelvic Pain: A Dyadic Daily Experience Study. AB - Provoked vestibulodynia (PVD), a common cause of women's genitopelvic pain, is associated with poorer psychological and sexual well-being in affected couples. Greater sexual contingent self-worth (CSW)-defined as self-esteem that is dependent on the perceived success or failure of a sexual relationship-has been linked to poorer well-being in a cross-sectional study of couples coping with PVD. This study aimed to examine whether daily sexual distress mediated the associations between greater sexual CSW and lower sexual satisfaction and greater anxiety, depressed mood, and women's pain in affected couples. Women (N = 125) diagnosed with PVD and their partners completed the Sexual CSW Scale and then online daily surveys for eight weeks measuring sexual distress, sexual satisfaction, anxiety, depressed mood, and women's pain during intercourse. Multilevel analyses were based on the actor-partner interdependence model (APIM). For women who had higher sexual CSW (compared to lower sexual CSW), on sexual activity days when their sexual distress was higher, they reported lower sexual satisfaction and greater anxiety, depressed mood, and pain (compared to their average level across all sexual activity days). Findings suggest that daily sexual distress may be one pathway between greater sexual CSW and poorer day-to day well-being in women with PVD. PMID- 30299978 TI - Intrinsic Parameters and Bacterial Growth Prediction in a Brazilian Minimally Ripened Cheese (Coalho) during Refrigerated Storage. AB - This study evaluated the microbiological and physicochemical characteristics in different commercial brands of a Brazilian minimally ripened (coalho) cheese during 60 days of storage under refrigeration. Combinations of maximum and minimum values of water activity and pH determined in cheese samples at refrigeration temperature (7 degrees C) were used in a bacterial growth prediction analysis. Maximum growth rate (Grmax) was estimated for different pathogenic and/or spoilage bacteria using the ComBase Predictor. Results of microbiological characterization analyses showed persistent high counts for all monitored microbial groups ( Lactobacillus spp., Lactococcus spp., Enterococcus spp., Staphylococcus spp., Enterobacteriaceae, proteolytic and lipolytic microorganisms, and fungi) in cheese samples; no dominant microbial group was observed over time. Values of pH (6.03 +/- 0.16 to 7.28 +/- 0.55), acidity (0.15% +/- 0.09% to 0.66% +/- 0.26%), sodium chloride (1.05% +/- 0.19% to 1.97% +/- 0.75%), and water activity (0.948 +/- 0.020 to 0.974 +/- 0.012) did not vary in cheese samples during storage. Estimated Grmax values for the tested bacteria were in the range of 0.004 to 0.044 log CFU/h. Highest Grmax values (0.005 to 0.044 log CFU/h) were predicted for the psychrotrophic Aeromonas hydrophila, Listeria monocytogenes, Pseudomonas spp., and Yersinia enterocolitica. Grmax values predicted for Escherichia coli, Salmonella spp., and Staphylococcus aureus were in the range of 0.004 to 0.016 log CFU/h. These results indicate unsatisfactory microbiological characteristics of commercially available coalho cheese. Physicochemical characteristics of commercial coalho cheese stored under refrigeration allow bacterial growth to occur, indicating higher risk for fast growth of contaminant bacteria in this product. PMID- 30299979 TI - Psocoptera (Psocodea) in Spice and Medicinal Dehydrated Plants Sold in Bulk in a Big Metropolis in Brazil. AB - In Brazil, the production of dried herbs and condiments is on a smaller scale than that of its other agricultural sectors; however, it has been growing and attracting new producers, driven by the stimulus to provide healthy and gourmet foods. Insects in the order Psocoptera may cause loss of quality in such dried foods, and because of their small size, these insects can be easily transported by commerce. No information is available on how these insects may be entering Brazil via the importation of dehydrated products or how they may be exported with the increase of Brazilian dried food production. To examine these issues, 10 sites offering foods sold in bulk within the city of Sao Paulo, Brazil, were chosen. At each food site, the same 20 species of aromatic spice and medicinal dehydrated plants were purchased. In the laboratory, they were analyzed for the presence of insects immediately after acquisition. After removal of nymphal and adult psocopterans, the plants were kept in vials under environmental conditions to be investigated 40 days later. Psocopterans were found in 12 of the 20 dehydrated plant species. Eleven psocopteran species were recorded, including six species of unidentified Liposcelis. Liposcelis bostrychophila (Badonnel) was found in all samples with the presence of insects. The other frequent species were Liposcelis entomophila (Enderlein) and Lepinotus reticulatus (Enderlein). Lepinotus reticulatus constitutes the first record in Brazil. In total, 1,021 insects were recorded in the evaluation right after purchase, and this number grew to 3,734 individuals recovered 40 days later under laboratory conditions. The data show that in a relatively short period of storage, a population increase occurs that may cause loss of product quality and a decrease in organoleptic properties. Thus, it is necessary to have greater surveillance of the products so that consumers have access to quality dehydrated foods. PMID- 30299980 TI - Development and Feasibility Testing of a Videogame Intervention to Reduce High Risk Sexual Behavior in Black and Hispanic Adolescents. AB - OBJECTIVE: Develop and test feasibility of a mobile videogame intervention to decrease high-risk sexual behavior in black and Hispanic adolescents. MATERIALS AND METHODS: Iterative design to develop intervention in partnership with target audience. Feasibility and preliminary impact data collected at baseline, following 2-3 hours of gameplay and at 8-week follow-up. RESULTS: Twenty-six 15 17-year-olds completed pilot testing: 16 (62%) were male, 20 (77%) black or Hispanic. Pilot testing demonstrated feasibility, including producing a usable videogame prototype, incorporating videogame testing within a high school, and participants' acceptability of the videogame. Participants' gameplay experience reflected that most would play the videogame again (77%), stated that they felt responsible for the choices they made in the videogame (73%), and would tell their friends to play the videogame (58%). Most suggested adding more videogame content to further engage participants. From baseline to follow-up, participants demonstrated improvements in condom and contraception self-efficacy (P = 0.003), risk perceptions (P = 0.009), and high-risk sexual behavior knowledge (P < 0.0001). Among black or Hispanic adolescents, we found improvements in summary measures of intentions (P = 0.04), self-efficacy (P = 0.003), risk perceptions (P = 0.002), and sexual knowledge (P = 0.0002). Adolescents with previous sexual experience showed similar improvements. CONCLUSION: Pilot testing of an innovative videogame, developed in partnership with the target audience, demonstrated feasibility and preliminary impact with this cohort of black or Hispanic adolescents. We developed a usable videogame prototype and gained important data about how to enhance the next videogame iteration. Future plans include targeting an older age group to maximize our ability to measure potential impact among sexually experienced adolescents. PMID- 30299981 TI - "I Felt Like I Was a Part of Trying to Keep My Baby Alive": Perspectives of Hispanic and Non-Hispanic Black Mothers in Providing Milk for Their Very Preterm Infants. AB - BACKGROUND: Compared with non-Hispanic white, Hispanic and non-Hispanic black mothers of very preterm infants are less likely to provide mother's milk at the point of hospital discharge; the perspectives of these mothers are poorly understood. OBJECTIVES: To examine the perceived barriers and facilitators of providing milk for very preterm infants during the hospitalization among Hispanic and non-Hispanic black mothers. MATERIALS AND METHODS: We conducted 23 in-depth, semistructured interviews of English and Spanish-speaking Hispanic and non Hispanic black mothers that initiated milk production for their very preterm infants, <=1,750 g at birth. Following thematic saturation, results were validated through expert triangulation and member checking. RESULTS: Twelve mothers were Hispanic, where three were English speaking and nine were Spanish speaking. Eleven mothers were non-Hispanic black and English speaking. We found themes pertaining to general experiences: (1) Breastfeeding intent impacts mothers' success in providing milk throughout the hospitalization; (2) Pumping milk for a hospitalized infant is repetitive, exhausting, and does not elicit the same emotional connection as breastfeeding; (3) Hospital providers are an important source of support, when sufficient time is spent to address ongoing issues; (4) Providing milk creates a unique sense of purpose when mothers otherwise feel a lack of control; and we found themes pertaining to the experiences of Hispanic and non-Hispanic black mothers: (1) Breastfeeding as a cultural norm influences mothers' intent to initiate and continue breastfeeding; (2) Hospital staff are viewed as more supportive when interactions and treatment are perceived as racially/ethnically unbiased and (3) when communication occurs in the primary language; and (4) Mother-infant separation creates logistical challenges that negatively impact ongoing milk production. CONCLUSIONS: While providing milk for a hospitalized very preterm infant is exhausting, and logistically challenging, Hispanic and non-Hispanic black mothers are inspired to do so because of their intent to breastfeed, support from hospital providers, and feelings of purpose. PMID- 30299982 TI - The Relationship Between Dimensions of Adult Attachment and Motivation for Faking Orgasm in Women. AB - Attachment and sexual behavior are both integral parts of adult romantic relationships. Attachment avoidance is linked to impersonal, egocentric sexual activities, whereas the sexuality of anxiously attached individuals revolves around relationship maintenance and the needs of the partner. In this attachment context, faking orgasm might serve as a means for relational regulation. The aim of our study was to investigate the links between dimensions of adult attachment and motives for faking orgasm in women. Young women completed measures of adult attachment and motivations for faking orgasm. Both attachment avoidance and attachment anxiety were related to the use of faked orgasm as a means to avoid negative, shameful feelings. Attachment avoidance was significantly associated with the intention to quickly end sexual intercourse through faking orgasm. Attachment anxiety was associated with the use of faked orgasm to increase sexual arousal and to elevate partners' self-esteem. Results are discussed with regard to relational and sexual goals associated with adult attachment orientations. PMID- 30299983 TI - Evaluation of the dental spectral cone beam CT for metal artefact reduction. AB - OBJECTIVES:: Metal artefacts are highly common in dental CT images because of the high X-ray attenuation of metallic dental fillings and implants. This study presents an evaluation of the virtual monochromatic imaging for metal artefact reduction by a recently introduced dental spectral cone beam CT, which is the first commercial dental spectral CBCT with flat-panel detector. METHODS:: We carried out phantom experiments and clinical trials in this study. In the phantom study, the head phantom with metallic dental fillings and implants of various materials was scanned. Moreover, standard deviation, metal artefact index, and contrast-to-noise ratio were analyzed for fixed region of interest. Patient study included 23 patients with metallic fillings and metal implants. Traditional CT images and virtual monochromatic images were produced in a single scan, ensuring that the comparison can be made within the same patient and same location. Standard deviation and metal artefact index were analyzed for fixed region of interest. RESULTS:: The phantom study and patient study showed that the metal artefacts caused by metallic dental fillings are well-suppressed by the virtual monochromatic imaging. Moreover, the improvements in virtual monochromatic imaging in terms of image quality are more pronounced for small dental fillings.. The noise increase in image slices without metallic objects is a side-effect of the virtual monochromatic images. CONCLUSIONS:: Virtual monochromatic imaging by spectral cone beam CT reduces the metal artefact and improves the image contrast to-noise ratio around dental metallic fillings. This kind of imaging would be recommended for patients with dental metallic fillings. PMID- 30299985 TI - Concussion Competencies: A Framework for School-based Concussion Management. PMID- 30299984 TI - Quality Control System in an Obstetrics and Gynecology Disease Biobank. AB - AIM: To ensure that sample quality meets the requirements of experimental research, the gynecology and obstetrics biobank of the Nanjing Drum Tower hospital designed different quality control methods for relevant types of samples. A range of quality control procedures has been formulated. METHODS: The sample types were frozen tissue, paraffin-embedded tissue, optimal cutting temperature (OCT)-embedded tissue, plasma, buffy coat, serum, blood clots, and urine. Different categories of samples from a random selection of 1% of cases were analyzed for quality control experiments: (i) frozen tissue, buffy coat, and blood clots: RNA and DNA were extracted and the concentration, purity, and integrity were determined; (ii) paraffin-embedded tissue: morphological observations were made after hematoxylin-eosin staining and immunohistochemical detection of beta-actin or CD10; (iii) OCT-embedded tissue: hematoxylin-eosin staining and immunofluorescence detection of beta-actin; and (iv) frozen tissue samples derived from different organs of 18 fetal autopsy specimens with different cold ischemia times (CITs), 0-12 hours, 12-18 hours, 18-24 hours, and 24-48 hours, were chosen to study RNA quality. There is no universally recognized quality control index for plasma, serum, and urine, so the quality of samples was evaluated from feedback from the research projects in which the samples were used. RESULTS: Currently, there are ~2000 cases and 360,000 sample vials in the biobank. According to the experiments, (i) the concentration and purity of all nucleic acids of selected samples were qualified; (ii) for frozen tissues with a CIT <=1 hour, using a qualified standard RNA quality number (RQN) >=7, the qualification rate was 90%; (iii) frozen tissues with CIT between 1 and 18 hours, using a qualified standard RQN >=5, the qualification rate was 61.1%; (iv) all of the paraffin-embedded tissues qualified for morphological observation; (v) the qualification rate of OCT-embedded tissue was 89%; and (vi) CIT had a great influence on the integrity of frozen tissue RNA. As the tissue CIT lengthened, the integrity of the RNA decreased. The RNA integrity parameters of different tissue types in the same specimen were significantly different. CONCLUSIONS: A quality control system was constructed in an obstetrics and gynecology disease biobank with various types of diseases and abundant samples. Using specific quality control experiments for different types of samples was a reliable operating strategy that can be beneficial for providing qualified research resources. For birth defect autopsy specimens, the samples used for RNA research should have a CIT of at least <12 hours. PMID- 30299986 TI - Quantifying the setup uncertainty of a stereotactic murine micro-image guided radiation therapy system. AB - OBJECTIVE:: Investigate the reproducibility of murine cranial positioning using solely a stereotactic stage, and quantify the potential improvements from the on board image guidance of the X-RAD SmART irradiator. METHODS:: For intermouse reproducibility, athymic nude mice (N = 5, *4 groups) were cranially fixed on a stereotactic stage. Each mouse was imaged via cone-beam CT (CBCT). A virtual isocenter target was placed in the brain, the stage shifted to that target, and the couch positions recorded. The mouse was removed from the stage and this process repeated twice (N=60 measurements). The first acquired CBCT coordinates (within each group of five mice) were used to define "stereotactic couch coordinates." CBCT shifts were calculated to quantify the accuracy of setup based on couch coordinates alone. For intramouse reproducibility, C57BL/6 mice (N=4) were imaged daily for 7 days. Each mouse had individual stereotactic coordinates defined from their first day of CBCT localization, and positional shifts required on the six subsequent days of imaging were quantified (N = 24 measurements). RESULTS:: The mean vector shift between stereotactic setup and CBCT alignment for inter and intramouse analysis was 0.78 +/- 0.27 mm and 0.82 +/- 0.34 mm, respectively. CONCLUSION:: Cranial irradiation that can permit positional uncertainties on the order of a millimeter can rely solely on stereotactic coordinates derived from a single daily CBCT. Irradiations of subregions requiring submillimeter accuracy require daily image guidance for each mouse. ADVANCES IN KNOWLEDGE:: This is the first investigation of stereotactic reproducibility using the X-RAD SmART and it suggests a method for increased efficiency in high-throughput experiments. PMID- 30299987 TI - Cognitive and Affective Theory of Mind in Mild Cognitive Impairment and Parkinson's Disease: Preliminary Evidence from the Italian Version of the Yoni Task. AB - The aim of the study was to explore cognitive and affective dimensions of ToM using the computerized Yoni task in participants with amnestic Mild Cognitive Impairment (aMCI=16), early stage of Parkinson's Disease (PD=14), and healthy controls (HC=18) Results demonstrated that the Yoni task was effective in discriminating between groups in 1th order cognitive dimension (MCI 0.05). A significant difference (p = 0.02) due to higher stiffness measurements using free-breathing MRE was observed for reader 2. There was excellent absolute agreement between MRE techniques for each reader (all ICCs > 0.940). Bias between techniques ranged from -0.102 to 0.089 kPa for reader 1, -0.119 to 0.121 kPa for reader 2, and 0.074 to 0.085 kPa for reader 3. CONCLUSION: Free-breathing and CS accelerated 2D GRE MRE techniques yield similar results to the conventional breath-held technique with only slight bias and may be useful in pediatric and adult patients with limited ability to breath-hold. PMID- 30300002 TI - Improving Diagnosis of Primary Prostate Cancer With Combined 68Ga-Prostate Specific Membrane Antigen-HBED-CC Simultaneous PET and Multiparametric MRI and Clinical Parameters. AB - OBJECTIVE: The current study was designed to test the diagnostic performance of 68Ga-prostate-specific membrane antigen (PSMA) PET and multiparametric MRI along with clinical parameters in the characterization of prostatic lesions. MATERIALS AND METHODS: Eighty-two men with 63 malignant and 21 benign histologically proven prostate lesions who underwent complete clinical workup were included in this retrospective study. All patients underwent simultaneous whole-body 68Ga-PSMA PET/MRI with dedicated multiparametric MRI. Prostate Imaging-Reporting and Data System (PI-RADS) version 2 assessment was used for predicting the likelihood of cancer. Uptake of 68Ga-PSMA was recorded by adopting the copy-and-paste function of ROIs defined on MR images. ROC and combined ROC analyses were performed to test the diagnostic accuracy of individual and combined parameters. Spearman analysis was used to assess the correlations. RESULTS: PSMA uptake (maximum standardized uptake value) was significantly different among tumors with Gleason scores of 7, 8, and 9, with the lowest uptake in tumors with a score of 7 and the highest uptake in tumors with a score of 9. There was a significant difference between early- and delayed-phase PSMA uptake in malignant prostatic lesions (p < 0.01). Significant correlations were observed between delayed and differential PSMA uptake and PI-RADS category (p < 0.01 and < 0.01, respectively), digital rectal examination findings (p = 0.01 and < 0.01, respectively), Gleason score (p = 0.05 and < 0.05, respectively), and prostate-specific antigen levels (p = 0.01 for both). Combined ROC analysis of prostate-specific antigen levels, digital rectal examination findings, multiparametric MRI, and differential PSMA uptake were able to characterize prostatic lesions with a mean (+/- SD) AUC of 0.94 +/- 0.03, compared with their individual AUCs of 0.77, 0.70, 0.82, and 0.88. CONCLUSION: Gallium-68-PSMA PET combined with multiparametric MRI showed high diagnostic accuracy for prostate cancer diagnosis compared with either multiparametric MRI or PET alone or with clinical factors (e.g., digital rectal examination or prostate-specific antigen level) alone, and the combination further improves characterization of prostatic lesions.

AB - OBJECTIVE: The purpose of this article is to review the normal postoperative appearance of various sternotomy configurations as well as the pathophysiologic and imaging characteristics of sternotomy complications on radiographs, MDCT, MRI, and scintigraphy. CONCLUSION: Clinical signs of sternotomy complications are nonspecific and often overlap with normal postoperative changes. Knowledge of normal and abnormal imaging findings is essential to guide management and treatment. PMID- 30300005 TI - Utility of FDG PET/CT in the Characterization of Sinonasal Neoplasms: Analysis of Standardized Uptake Value Parameters. AB - OBJECTIVE: We aimed to evaluate the contribution of different standardized uptake value (SUV) parameters generated from pretreatment 18F-FDG PET/CT in the characterization of sinonasal neoplasms with histopathologic correlations. MATERIALS AND METHODS: This retrospective study included 97 consecutive patients (58 men, 39 women; age range, 20-93 years; mean age, 62 years) with pathologically proven untreated sinonasal neoplasms who underwent FDG PET/CT from February 2010 to August 2017. Semiquantitative analysis of primary tumors were performed to evaluate the maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), and the ratio of the SUVmax of the primary tumor to the SUVmean of mediastinal blood pool, which we refer to here as " SUVratio." Various sinonasal tumor histopathologic subgroups (n = 14) were analyzed. The Kruskal-Wallis test was used to compare the SUVmax, SUVmean, and SUVratio with the histopathologic diagnosis. RESULTS: Mean values of SUVmax, SUVmean, and SUVratio for the sinonasal neoplasms were 16.6 +/- 9.7 (SD), 8.6 +/- 5.1, and 5.9 +/- 3.7, respectively, and each parameter was significantly different between histopathologic types (p < 0.05). Mean values of SUVmax, SUVmean, and SUVratio were higher in sinonasal undifferentiated carcinoma (SNUC) than in olfactory neuroblastoma, metastasis, and adenoid cystic carcinoma (p < 0.05). Mean values of SUVmax and SUVmean were higher in squamous cell carcinoma (SCC) than in olfactory neuroblastoma and metastasis (p < 0.05). Also, mean SUVmax was higher in SCC and SNUC than in poorly differentiated carcinoma (p < 0.05). Mean SUVratio was higher in SCC than in small cell carcinoma, olfactory neuroblastoma, and adenoid cystic carcinoma (p < 0.05). CONCLUSION: We conclude that different SUV parameters from FDG PET/CT can be used as so-called "metabolic biopsy" to categorize sinonasal neoplasms into different histopathologic subgroups because it can help in the characterization of some of the more common subgroups of sinonasal neoplasms. However, we found that there is overlap in FDG uptake values among some of the rare histologic subgroups; hence, surgical biopsy is still needed for differentiation of histologic subtypes of aggressive sinonasal masses.

AB - OBJECTIVE: The purpose of this study is to determine whether a deep convolutional neural network (DCNN) trained on a dataset of limited size can accurately diagnose traumatic pediatric elbow effusion on lateral radiographs. MATERIALS AND METHODS: A total of 901 lateral elbow radiographs from 882 pediatric patients who presented to the emergency department with upper extremity trauma were divided into a training set (657 images), a validation set (115 images), and an independent test set (129 images). The training set was used to train DCNNs of varying depth, architecture, and parameter initialization, some trained from randomly initialized parameter weights and others trained using parameter weights derived from pretraining on an ImageNet dataset. Hyperparameters were optimized using the validation set, and the DCNN with the highest ROC AUC on the validation set was selected for further performance testing on the test set. RESULTS: The final trained DCNN model had an ROC AUC of 0.985 (95% CI, 0.966-1.000) on the validation set and 0.943 (95% CI, 0.884-1.000) on the test set. On the test set, sensitivity was 0.909 (95% CI, 0.788-1.000), specificity was 0.906 (95% CI, 0.844 0.958), and accuracy was 0.907 (95% CI, 0.843-0.951). CONCLUSION: Accurate diagnosis of traumatic pediatric elbow joint effusion can be achieved using a DCNN. PMID- 30300007 TI - Downstream Costs Associated With Incidental Pancreatic Cysts Detected at MRI. AB - OBJECTIVE: The purpose of this study is to assess downstream costs associated with pancreatic cysts incidentally detected at MRI. MATERIALS AND METHODS: Two hundred patients with an incidental pancreatic cyst detected at MRI were identified. Downstream events (imaging, office visits, endoscopic ultrasound guided fine-needle aspiration, or chemotherapy) were identified from the electronic medical record. Radiologists' recommendations and ordering physician management were classified relative to the American College of Radiology (ACR) incidental findings committee recommendations. Costs for the downstream events were estimated using national Medicare rates and a 3% annual discount rate. Mean costs were computed. RESULTS: Estimated downstream costs averaged $460 per cyst ($872 per cyst with any follow-up testing). Nine patients had a clinically relevant outcome during follow-up (increase in cyst size, development of new cyst, or development of pancreatic cancer). Downstream cost per cyst with a clinically relevant outcome was $1364. Costs were greater when ordering physicians overmanaged ($842) versus when they were adherent ($631) or undermanaged ($252) relative to radiologist recommendation. Although costs were $252 when ordering physicians undermanaged relative to ACR incidental findings committee recommendations, costs were similar when ordering physicians were adherent ($811) or overmanaged ($845) relative to ACR incidental findings committee recommendations. Costs did not vary significantly according to whether radiologists recommended follow-up testing ($317-$491) or whether radiologist recommendations were adherent, undermanaged, or overmanaged relative to ACR incidental findings committee recommendations ($344-$528). CONCLUSION: The findings suggest a role for targeted educational efforts, collaborative partnerships, and other initiatives to foster greater adherence to radiologist recommendations, including critical test results notification systems, automated reminders within electronic health systems, and stronger language within radiology reports when no follow-up testing is recommended. PMID- 30300008 TI - Venous Malformations: Phleboliths Correlate With the Presence of Arteriovenous Microshunts. AB - OBJECTIVE: The objective of this study was to identify differences between venous malformations (VMs) with arteriovenous (AV) microshunts and VMs without AV microshunts. MATERIALS AND METHODS: In this retrospective study, 83 patients with untreated VMs of the extremities underwent a prospectively defined MRI protocol performed at 3 T. MR images were reviewed to determine localization and extent of each VM and tissue involvement. The VM volume and the lesion volume relative to body surface were measured. The number of phleboliths within the lesions was determined. Using time-resolved MR angiography, the hemodynamic subtype (VM with AV microshunts versus VM without AV microshunts) was classified, and the interval between the onset of arterial enhancement and lesion enhancement (tonset) was measured. Clinical data were reviewed to determine patient demographic characteristics, the onset of symptoms, the frequency of thrombophlebitis, and the pain score. RESULTS: Of the 83 patients, 56 (67%) presented with AV microshunts. The tonset (p <= 0.001), absolute and relative lesion volume (p = 0.001), and number of phleboliths (p = 0.038) differed significantly between these two subgroups. With use of a multivariable regression model, the strongest indicator for VM with AV microshunts was the presence of more than two phleboliths (odds ratio, 2.80; p = 0.007). No differences were noted regarding patient demographic characteristics and history or lesion morphologic features or anatomy. CONCLUSION: Occurrence of AV microshunts in untreated VM is a frequent phenomenon. This hemodynamic subtype is significantly associated with phleboliths and large lesions. The subtypes did not differ in terms of history and clinical course. PMID- 30300009 TI - Association of the Gross Appearance of Intratumoral Vascularity at MDCT With the Carbonic Anhydrase IX Score in Clear Cell Renal Cell Carcinoma. AB - OBJECTIVE: The purpose of this study was to determine whether qualitative MDCT features are associated with the carbonic anhydrase IX (CAIX) score of clear cell renal cell carcinoma (RCC). The CAIX score has been previously found to have prognostic significance for disease-free survival, overall survival, and lymph node involvement. MATERIALS AND METHODS: A cohort of 105 histologically proven clear cell RCCs in patients who underwent preoperative four-phase renal mass MDCT was derived from 2001 to 2013. Two genitourinary radiologists evaluated each lesion for the gross appearance of intratumoral vascularity, calcification, enhancement pattern, necrosis, margin, collecting system invasion, and renal vein invasion. Immunohistochemical analysis was used to determine the CAIX score (defined as the positive staining percentage multiplied by the staining intensity). Logistic and linear regression analyses were performed. RESULTS: In a linear regression model controlled for lesion size and stage, the gross appearance of intratumoral vascularity had a significant positive association with CAIX score (beta = 38.33, p = 0.010). In a logistic regression model controlled for lesion size and stage, the gross appearance of intratumoral vascularity had an odds ratio of 2.85 (p = 0.019) in differentiating clear cell RCCs with a CAIX score of 200-300 from clear cell RCCs with a CAIX score of 0 199. CONCLUSION: In clear cell RCCs, the gross appearance of intratumoral vascularity at MDCT was significantly associated with CAIX score, a prognostically significant molecular marker. Current assessment of CAIX score requires pathologic tissue sampling and immunohistochemical analysis. A noninvasive imaging biomarker that may help predict CAIX score may be of great clinical value. PMID- 30300010 TI - Angiotensin-(1-7) Contributes to Insulin-Sensitizing Effects of Angiotensin Converting Enzyme Inhibition in Obese Mice. AB - Angiotensin converting enzyme (ACE) inhibitors reduce body weight, lower blood pressure (BP), and improve insulin sensitivity in animal models of cardiometabolic syndrome. These effects are generally attributed to reduced angiotensin (Ang) II formation; however, these therapies also increase levels of Ang-(1-7), a beneficial hormone opposing Ang II actions. We hypothesized this Ang (1-7) generation contributes to the insulin sensitizing effects of ACE inhibition in obese mice. Adult male C57BL/6J mice were placed on a 60% high fat diet for 11 weeks. During the last 3 weeks of diet, mice received normal water or water containing the ACE inhibitor captopril (50 mg/L) as well as the Ang-(1-7) mas receptor antagonist A779 (400 or 800 ng/kg/min) or saline vehicle via subcutaneous osmotic mini-pumps. At the end of treatment, arterial BP was measured and hyperinsulinemic-euglycemic clamps were performed in conscious obese mice receiving vehicle, captopril, captopril plus A779, or A779 (n=6-13/group). Captopril reduced body weight (28+/-2 vs. 41+/-2 g saline; p=0.001), lowered systolic BP (109+/-6 vs.144+/-7 mmHg saline; p=0.041), and improved whole-body insulin sensitivity (steady-state glucose infusion rate: 31+/-4 vs. 16+/-2 mg/kg/min saline; p=0.001) in obese mice. A779 attenuated captopril-mediated improvements in insulin sensitivity (23+/-2 mg/kg/min; p=0.042), with no effect on body weight (32+/-2 g; p=0.441) or BP (111+/-7 mmHg; p=0.788). There was no effect of A779 alone on cardiometabolic outcomes. These data suggest that insulin sensitizing effects of ACE inhibition are in part due to activation of Ang-(1 7)/mas receptor pathways, and provide new insight into mechanisms underlying the positive metabolic effects of these therapies. PMID- 30300011 TI - Multi-omics Approach Reveals Metabolic Changes in the Heart at Birth. AB - During late gestation, the fetal heart primarily relies on glucose and lactate to support rapid growth and development. While numerous studies describe changes in heart metabolism to preferentially utilize fatty acids a few weeks after birth, little is known about metabolic changes of the heart within the first day following birth. Therefore, we used the ovine model of pregnancy to investigate metabolic differences between the near-term fetal and the newborn heart. Heart tissue was collected for metabolomic, lipidomic, and transcriptomic approaches from the left and right ventricles and intraventricular septum in 7 fetuses at gestational day 142 and 7 newborn lambs on the day of birth. Significant metabolites and lipids were identified using a Student's t-test, while differentially expressed genes were identified using a moderated t-test with empirical Bayes method (FDR-corrected p<0.10). Single-sample gene set enrichment analysis (ssGSEA) was used to identify pathways enriched on a transcriptomic level (FDR-corrected p<0.05), while over-representation enrichment analysis (ORA) was used to identify pathways enriched on a metabolomic level (p<0.05). We observed greater abundance of metabolites involved in butanoate and propanoate metabolism, and glycolysis in the term fetal heart and differential expression in these pathways were confirmed with ssGSEA. Immediately following birth, newborn hearts displayed enrichment in purine, fatty acid, and glycerophospholipid metabolic pathways, as well as oxidative phosphorylation with significant alterations in both lipids and metabolites to support transcriptomic findings. A better understanding of metabolic alterations that occur in the heart following birth may improve treatment of neonates at risk for heart failure. PMID- 30300012 TI - Leptin contributes to the beneficial effects of insulin treatment in streptozotocin-diabetic male mice. AB - It was long thought that the only hormone capable of reversing the catabolic consequences of diabetes was insulin. However, various studies have demonstrated that the adipocyte-derived hormone leptin can robustly lower blood glucose levels in rodent models of insulin-deficient diabetes. In addition, it has been suggested that some of the metabolic manifestations of insulin-deficient diabetes are due to hypoleptinemia as opposed to hypoinsulinemia. Since insulin therapy increases leptin levels, we sought to investigate the contribution of leptin to the beneficial effects of insulin therapy. To do this we tested insulin therapy in STZ-diabetic mice that were either on an ob/ob background or that were given a leptin antagonist to determine if blocking leptin action would blunt the glucose lowering effects of insulin therapy. We found that STZ diabetic ob/ob mice have a diminished blood glucose lowering effect in response to insulin therapy compared STZ diabetic controls and exhibited more severe weight loss post STZ-injection. In addition, STZ diabetic mice administered a leptin antagonist through daily injection or plasmid expression respond less robustly to insulin therapy as assessed by both fasting blood glucose levels and blood glucose levels during an oral glucose tolerance test. However, leptin antagonism did not prevent the insulin-induced reduction in beta-hydroxybutyrate and triglyceride levels. Therefore, we conclude that elevated leptin levels can contribute to the glucose lowering effect of insulin therapy in insulin-deficient diabetes. PMID- 30300013 TI - The rise of transcutaneous drug delivery for the management of alopecia: A review of existing literature and an eye towards the future. AB - INTRODUCTION: Fractional lasers and microneedling devices are increasingly used with topical drugs to treat various conditions, including alopecia, as they grant access to dermal structures such as hair follicles and cutaneous vasculature. OBJECTIVE: To perform a comprehensive review on transcutaneous drug delivery for the management of alopecia. METHODS: PubMed, Embase, and Ovid Medline databases were searched using terms including: alopecia, microneedling, lasers, androgenetic alopecia (AGA), alopecia areata (AA), drug delivery. Articles were examined for inclusion criteria: diagnosis of alopecia regardless of type, use of fractional laser or microneedling devices, and subsequent administration of topical medication. RESULTS: 8 studies, 6 prospective clinical trials and 2 case series, examining either AA or AGA were identified. For AA, five studies examined microneedling together with topical triamcinolone in three of these, while two studies used photodynamic therapy. Regarding AGA, two studies used topical minoxidil plus microneedling, and one examined topical finasteride with fractional erbium glass laser. Improvement was seen in 6 of the 8 studies. DISCUSSION: Transcutaneous drug delivery via fractional laser and microneedling is a promising modality with preliminary evidence for increased hair regrowth over topical therapy alone. Further studies are needed to elucidate treatment parameters and appropriate device selection for drug delivery. PMID- 30300014 TI - Comparison between microwave ablation and bipolar radiofrequency ablation in benign thyroid nodules: differences in energy transmission, duration of application and applied shots. AB - PURPOSE: Comparison between different thermal ablation systems for thyroid nodules regarding their different procedural characteristics such as treatment time, number of shots and energy transmission in the context of their clinical performance such as complication rate and volume reduction after three months. METHODS: A total of 60 patients with 65 nodules underwent thermal ablation of thyroid nodules with either microwave ablation (MWA) (9 male, 15 female and mean age 57 +/- 13 years) or radiofrequency ablation (RFA) (12 male, 24 female and mean age 54 +/- 12 years). RESULTS: Mean initial volume (MWA: 23.90 +/- 17.35 ml; RFA: 29.44 +/- 30.09 ml), energy transmission (MWA: 13.56 +/- 10.17 kJ; RFA: 15.12 +/- 13.45 kJ), energy transmission per ml (MWA: 0.85 +/- 1.01 kJ/ml; RFA: 0.65 +/- 0.32 kJ/ml), power (MWA: 22.69 +/- 12.32 J/s; RFA: 20.97 +/- 7.86 J/s) and duration of ablation (MWA: 618 +/- 304 s; RFA: 695 +/- 463 s) were not statistically different (p > .05). MWA required significantly less shots (MWA: 3 +/- 1; RFA: 6 +/- 3) than RFA (p < .05). At three-months follow-up a significant mean nodular volume reduction of 53.54 +/- 15.40% after MWA and 51.21 +/- 16.58% after RFA (p < .05) was measured. However, mean nodular volume reduction was not significantly different between both systems (p > .05). One patient treated by MWA reported a transient Horner's syndrome, which recovered without any further treatment. Major complications such as nodule rupture, infection or persisting nerve injuries did not occur. CONCLUSION: Both systems are suitable to treat thyroid nodules and show no significant difference in the duration of application, energy transmission and volume reduction. However, MWA requires less shots to treat the whole nodule. PMID- 30300016 TI - Effects of Carbohydrate, Caffeine and Guarana on Cognitive Performance, Perceived Exertion and Shooting Performance in High Level Athletes. AB - PURPOSE:: This study aimed at investigating the effect of carbohydrate (CHO), caffeine (CAF) and a guarana complex (GUAc) ingestion during a running exercise on cognitive performance, ratings of perceived exertion (RPE) and shooting performance in high level Modern Pentathlon athletes. METHODS:: Ten athletes completed four counterbalanced sessions within a 2 week-period, corresponding to ingestions of CHO (30 g), GUAc (300 mg), CAF (200 mg) or placebo (PL). The exercise involved a 40-minute run on a treadmill at a steady speed, previously determined as a "somewhat hard" exercise (RPE 13). Shooting and cognitive performances (Simon task) were assessed in three phases: 1) prior to exercise and ingestion, 2) prior to exercise and after half ingestion, and 3) after exercise and full ingestion. Ingestions were consumed 40 minutes (250 ml) and 5 minutes (125 ml) prior to exercise, and after 20 minutes of run (125 ml). RPE was assessed at 10 minutes intervals during exercise. RESULTS:: Results have shown an interaction between drinks and exercise on mean reaction time (p = .01, np2= .41) and a drinks effect on RPE (p = .01, np2 = .15). CHO, CAF and GUAc enhanced the speed of information processing after exercise (respectively p = .003, p = .004 and p = .04) but only CAF and GUAc decreased RPE (respectively p = .002, p = .02). CONCLUSIONS:: Our results highlight the beneficial effect of nutritional supplements on information processing and RPE. This finding is particularly interesting since decision-making processes are vital in many sports performance. PMID- 30300015 TI - Differences in Sprint Mechanical Force-Velocity Profile Between Trained Soccer and Futsal Players. AB - PURPOSE:: This study aimed to compare the sprint mechanical force-velocity (F-V) profile between soccer and futsal players. A secondary aim was, within each sport, to study the differences in sprint mechanical F-V profile between sexes and players of different levels. METHODS:: 102 soccer players (63 men) and 77 futsal players (49 men) that were competing from the elite to amateur levels in the Spanish league participated in this investigation. The testing procedure consisted of 3 unloaded maximal 40-m sprints. The velocity-time data recorded by a radar device was used to calculate the variables of the sprint acceleration F-V profile (maximal theoretical force [F0], maximal theoretical velocity [V0], maximal power [Pmax], decrease in the ratio of horizontal-to-resultant force [DRF], and maximal ratio of horizontal-to-resultant force [RFpeak]). RESULTS:: Futsal players showed a higher F0 than soccer players (effect size [ES] range: 0.11 to 0.74), while V0 (ES range: -0.48 to -1.15) and DRF (ES range: -0.75 to 1.45) was higher for soccer players. No significant differences were observed between soccer and futsal players for Pmax (ES range: -0.43 to 0.19) and RFpeak (ES range: -0.49 to 0.30). Men and high-level players presented an overall enhanced F-V profile compared to women and their lower-level counterparts, respectively. CONCLUSIONS:: The higher F0 and lower V0 of futsal players could be caused by the specific game's demand (larger number of accelerations but of shorter distances compared to soccer). These results show that the sprint mechanical F-V profile is able to distinguish between soccer and futsal players. PMID- 30300017 TI - Whole-body vibration in the reduction of the cellulite. AB - OBJECTIVE: Evaluate the effects of the whole body vibration in improving of cellulite in the women's gluteal region. METHODS: Controlled clinical trial performed with 42 women, with cellulite in the gluteal region, detected by means of clinical examination. After evaluation, the women were divided into two groups: Whole-Body Vibration (WBV_G) and control (C_G). The evaluations were performed at the beginning and the end of 10 sessions and superficial skin temperature, perimetry in the gluteal region, analysis of body contouring, analysis of improvement by blind reviewers and instrument of satisfaction, by numeric scale were investigated. RESULTS: In the thermographic analysis, the WBV_G obtained significant increase of superficial skin temperature on the right (p = 0.02) and left (p = 0.02) gluteal region. There was no difference in intra- and intergroups in perimetry and the analysis of body contour. The WBV_G obtained a higher percentage of improvement by assessment of the blind reviewers (p = 0.003) and greater aesthetics satisfaction (p = 0.006), when compared to C_G. CONCLUSION: WBV provided an improvement in the aspect of the cellulite when assessed by blind reviewers and greater participants' satisfaction, providing a significant increase in the superficial skin temperature in the gluteal region. PMID- 30300018 TI - Neoadjuvant chemotherapy plus radiation versus chemotherapy plus regional hyperthermia in high-grade soft tissue sarcomas: a retrospective comparison. AB - PURPOSE: Localized adult high-grade soft tissue sarcomas (STS) usually require multimodality treatment including surgery, radiotherapy, chemotherapy and hyperthermia. If maximal preoperative tumor-shrinkage is envisaged, neoadjuvant chemotherapy + radiation (CRT) is often applied, however at the expense of relatively high toxicities and increased postoperative complication rates. This study aims to compare preoperative CRT with neoadjuvant chemotherapy + regional hyperthermia (HCT) regarding histopathological response, toxicity and outcome. METHODS: In this retrospective analysis, 61 consecutive high-grade STS patients treated between 2009 and 2016 were included. All patients were treated within a prospective treatment protocol. 28 patients received neoadjuvant CRT 33 patients HCT. CRT consisted of four cycles doxorubicin/ifosfamide and two cycles ifosfamide concomitant to 50.4 Gray external beam radiotherapy. HCT consisted of 4-6 cycles doxorubicin/ifosfamide with deep regional hyperthermia administered bi weekly during each cycle. Association of treatment modality with overall survival (OS), local control (LC) and freedom from distant metastases (FFDM) was evaluated by Kaplan-Meier and log-rank analyses. RESULTS: The overall patient characteristics were well balanced. Histopathological tumor response did not differ significantly between both groups (p = .67), neither did higher-grade toxicities during neoadjuvant treatment. Wound dehiscence (p = .018) and surgical hospital re-admissions (p < .001) were both significantly more frequent in the CRT group. Two-year OS, LC and FFDM rates of all patients were 93, 85 and 71% with no significant differences between CRT and HCT. CONCLUSION: Compared to CRT, HCT seems equally efficient and appears to bear less surgical complications. Interpretation should be cautious due to the low number of patients and the retrospective nature of this study. PMID- 30300020 TI - Intense pulsed light vs silicone gel sheet in the management of hypertrophic scars: an interventional comparative trial in the Indian population. AB - INTRODUCTION: Hypertrophic scars are abnormal scars that are a source of great functional, psychological and financial burden to the patient. Currently available treatment modalities are either very cumbersome to use or have not provided very satisfactory results. Intense pulsed light (IPL) therapy for the management of hypertrophic scars has been recently introduced. However, most of the studies available are from the Western population. In this trial, we aim to study the effect of IPL on the South Indian population with darker skin and compare it with an existing treatment modality (silicone gel sheet). MATERIALS AND METHODS: This trial was an interventional clinical trial conducted from September 2015 to March 2017 on 28 patients with 65 hypertrophic scars. Each scar was divided into 2 equal parts (4.6 x 1 cm2). One half of the scar was treated to 4 sessions of 29J/cm2 of IPL at 3 weekly intervals. A silicone gel sheet (SGS) was applied over the other half and changed at 3 weekly intervals. The Vancouver scar scale was used to grade both halves of the scar before treatment, at each visit and 3 weeks after treatment completion. RESULTS: Scars treated with IPL showed a significant reduction in the pliability (p=0.002) and hyperpigmentation (p=0.000) as compared to scars treated with SGS. Though the percentage reduction in the height of the scar was more in the IPL group (15.4% as compared to 4.6%in the SGS group), the result was not statistically significant (p<0.065). As most scars in our study showed normal vascularity at the beginning, the percentage reduction in vascularity between both groups was the same (p<0.597). The reduction in the median VSS score was more in the IPL group compared to SGS group (p=0.00). CONCLUSION: IPL therapy offers a safe and effective means of hypertrophic scar treatment, especially on large scars where other treatment modalities may not be feasible. Minimal side effects that occur can be prevented with proper pre, intra and post procedure cooling. PMID- 30300021 TI - Randomized, side-by-side comparison of a topical photo-enhancer gel for hair removal: an efficacy and safety study. AB - BACKGROUND: Novel protocols are evolving to enhance hair follicle damage while preserving safety and improving efficacy. OBJECTIVES: The safety and tolerability of a 755-nm diode laser was compared to a combined laser with topical photo enhancer gel ("combined") versus laser alone ("solo"). METHODS: Twenty women (age 23-33 years old), Fitzpatrick skin type I-V, were randomized to side-by-side comparisons with a laser hair removal protocol. The combined side received reduced laser energy compared to the solo side. The laser used in-motion super hair removal technology. Subjects received up to four treatments. Subjects were assessed at baseline and at 1 and 6 months after the last treatment. RESULTS: At the 1-month follow-up, there were no statistical differences in percent hair reduction between the combined (81 +/- 16%) versus the solo (77 +/- 15%) protocols (p > 0.05). Similarly, at 6-month follow-up, there are no statistical differences between the combined (71 +/- 24%) versus the solo (70 +/- 23%) treatment protocols (p > 0.05). The average accumulative laser energy in the combined side was half of the solo side (4.2 +/- 1.6 vs. 7.6 +/- 2.7 kJ, respectively). Pain during the procedure was significantly higher in the solo (5.5 +/- 1.8) versus the combined (3.8 +/- 1.7) protocol (p < 0.001). CONCLUSION: A laser hair removal paradigm that combines a 755-nm diode laser with a photo enhancer gel (reduced kJ protocol) is clinically effective as a solo treatment protocol. PMID- 30300019 TI - Applying lessons from human papillomavirus vaccines to the development of vaccines against Chlamydia trachomatis. AB - INTRODUCTION: Chlamydia trachomatis (Ct), the most common bacterial sexually transmitted infection (STI), leads to pelvic inflammatory disease, infertility, and ectopic pregnancy in women. In this Perspective, we discuss the successful human papillomavirus (HPV) vaccine as a case study to inform Ct vaccine efforts. Areas covered: The immunological basis of HPV vaccine-elicited protection is high titer, long-lasting antibody responses in the genital tract which provides sterilizing immunity. These antibodies are elicited through parenteral administration of a subunit vaccine based on virus-like particles (VLPs) of HPV. We present three lessons learned from the successful HPV vaccine efforts: (1) antibodies alone can be sufficient to provide protection from STIs in the genital tract, (2) the successful generation of high antibody levels is due to the multivalent structure of HPV VLPs, (3) major challenges exist in designing vaccines that elicit appropriate effector T cells in the genital tract. We then discuss the possibility of antibody-based immunity for Ct. Expert commentary: In this Perspective, we present a case for developing antibody-eliciting vaccines, similar to the HPV vaccine, for Ct. Basic research into the mechanisms of Ct entry into host cells will reveal new vaccine targets, which may be antigens against which antibodies are not normally elicited during natural infection. PMID- 30300022 TI - Microwave ablation followed by immediate biopsy in the treatment of non-small cell lung cancer. AB - BACKGROUND: To evaluate the efficacy and safety of microwave ablation (MWA) followed by immediate biopsy in the treatment of non-small cell lung cancer (NSCLC) and to clarify whether pathology changes can predict treatment responses and patient survival. METHODS: Patients with pathologically confirmed NSCLC pre ablation were treated with MWA, and immediate biopsy was carried out right after ablation in one procedure. Pathology changes were categorized according to the pre- and postablation pathology: Group A, same histology type; Group B, paired histology type with burning degeneration; Group C, no definite histology type; Group D, no definite cancer cells. The internal correlations between pathology changes and baseline characteristics, responses to MWA and survival were evaluated. RESULTS: A total of 68 patients were enrolled in the study, of which 19, 28, 11 and 10 patients were classified into Group A, Group B, Group C and Group D, respectively. In total, 85.3 and 69.1% patients were diagnosed with malignant tumors and the same pathology type, respectively. No significant difference in clinical-pathologic characteristics or response to MWA between the groups was observed. Upon combining Groups A, B and C, Group D exhibited longer progression-free survival (PFS) (Groups A + B + C versus Group D, 11.7 months, 95% CI 9.6-13.7 versus 26.6 months, 95% CI 19.0-34.2, p = .253) and overall survival (OS) (15.9 months, 95% CI 14.2-17.5, versus 29.8 months, 95% CI, 24.3 35.3, p = .395), although no significant differences were observed. Complications were identified in 63 (92.6%), of which 17 (25.0%) patients had major complications. CONCLUSIONS: Immediate biopsy post-MWA can distinguish cancer cells or histology types in most cases of NSCLC. However, pathology changes pre- and postablation could not predict the response to MWA and patient survival. PMID- 30300023 TI - Anaerobic Speed Reserve: A Key Component of Elite Male 800m Running. AB - PURPOSE:: In recent years (2011-2016), men's 800m championship running performances have required greater speed than previous eras (2000-2009). The "Anaerobic speed reserve" (ASR) may be a key differentiator of this performance, but profiles of elite 800m runners and its relationship to performance time have yet to be determined. METHODS:: The ASR - determined as the difference between maximal sprint speed (MSS) and predicted maximal aerobic speed (MAS) - of 19 elite 800m and 1500m runners was assessed using 50m sprint and 1500m race performance times. Profiles of three athlete sub-groups were examined using cluster analysis and the speed reserve ratio (SRR), defined as MSS/MAS. RESULTS:: For the same MAS, MSS and ASR showed very large negative (both r=-0.74+/-0.30, +/ 90% confidence limits; very likely) relationships with 800m performance time. In contrast, for the same MSS, ASR and MAS had small negative relationships (both r= 0.16+/-0.54), possibly) with 800m performance. ASR, 800m personal best, and SRR best defined the three sub-groups along a continuum of 800m runners, with SRR values as follows: 400-800m >=1.58, 800m <=1.57 to >=1.47, and 800-1500m as <=1.47 to >= 1.36. CONCLUSIONS:: MSS had the strongest relationship with 800m performance, whereby for the same MSS, MAS and ASR showed only small relationships to differences in 800m time. Further, our findings support coaching observation of three 800m sub-groups, with the SRR potentially representing a useful and practical tool for identifying an athlete's 800m profile. Future investigations should consider the SRR framework and its application for individualised training approaches in this event.

AB - PURPOSE:: The purpose of the current study was to determine the reliability and validity of a novel trunk maximal isometric force assessment involving seven different tasks with 200 m times for elite sprint flatwater kayakers. METHODS:: Ten elite sprint flatwater kayakers, performed a series of maximal isometric voluntary contractions (MVCs) on two separate days to assess reliability. MVC force was assessed as the participants sat on a modified kayak ergometer and applied their maximal isometric force to a uniaxial load cell during seven different tasks. The seven tasks of interest were a seated trunk forward flexion (FF), bilateral rotational pulls (RTPLL, RTPLR), bilateral rotational pushes (RTPSL, RTPSR), and a sport specific bilateral kayak stroke simulation (SIML, SIMR). Twenty elite flatwater kayak athletes (10 male, 10 female) participated in the validity portion by completing the series of tasks in conjunction with a 200 m race. RESULTS:: MVC force values ranged from 84 N to 800 N across all participants and all tasks. The average coefficient of variation (CV) of the seven tasks ranged from 2.4% to 7.7%. Regression analysis showed Pearson correlations ranging from -0.84 to -0.22 for both absolute and relative values with 200 m performance times. CONCLUSIONS:: MVC force measured in each task was considered reliable as a small degree of variance between trials was found. The summation of the seven trunk scores showed very strong correlations with on-water performance, indicating this assessment is valid for elite sprint kayakers. PMID- 30300025 TI - Relationship Between Various Training Load Measures in Elite Cyclists during Training, Road Races and Time Trials. AB - PURPOSE:: The relationship between various training load (TL) measures in professional cycling is not well explored. This study investigates the relationship between mechanical energy spent (in kJ), sRPE, LuTRIMP and TSS in training, races and time trials (TT). METHODS:: From 4 consecutive years field data was collected from 21 professional cyclists and categorized as being collected in training, racing or TT's. kJ spent, sRPE, LuTRIMP and TSS were calculated and the correlations between the various TL's were made. RESULTS:: 11,655 sessions were collected from which 7,596 sessions had heart rate (HR) data and 5,445 sessions had an RPE-score available. The r between the various TL's during training was almost perfect. The r between the various TL's during racing was almost perfect or very large. The r between the various TL's during TT's was almost perfect or very large. For all relationships between TSS and one of the other measurements of TL (kJ spent, sRPE and LuTRIMP) a significant different slope was found. CONCLUSIONS:: kJ spent, sRPE, LuTRIMP and TSS have all a large or almost perfect relationship with each other during training, racing and TT's but during racing both sRPE and LuTRIMP have a weaker relationship with kJ spent and TSS. Further, the significant different slope of TSS versus the other measurements of TL during training and racing has the effect that TSS collected in training and road-races differ by 120% while the other measurements of TL (kJ spent, sRPE and LuTRIMP) differ by only 73%, 67%, and 68% respectively). PMID- 30300026 TI - The assessment of the effects of the combination of microdermabrasion and cavitation peeling in the therapy of seborrhoeic skin with visible symptoms of acne punctata. AB - OBJECTIVE: The aim of this study was to assess objectively the effects of the combination of corundum microdermabrasion and cavitation peeling in the therapy of seborrheic skin with visible symptoms of acne punctata. MATERIAL AND METHODS: The study involved a group of nine women. A series of six treatments with the combination of microdermabrasion and cavitation peeling were performed within facial skin at 10-14 days intervals. Corneometric measurements examining skin hydration level and sebumetric measurements analyzing skin sebum level were made before the series of treatments and after second, fourth and sixth procedure in five facial areas. Clinical assessment of the efficacy of the therapy was performed on the basis of photographic documentation (Fotomedicus). Anonymous questionnaires were used in order to evaluate patients' satisfaction rate. RESULTS: Statistically significant improvement in skin sebum level was observed in all examined areas (forehead p = 0.002; nose p = 0.001, chin p = 0.01, left cheek p = 0.009, right cheek p = 0.007). In case of skin hydration, significant improvement was found only in the area of chin (p = 0.03). 78% of participants estimated that the improvement was in the range of 55-70%, while 22% of participants of 75-100%. The reduction in the amount and visibility of comedones and pimples were demonstrated on the basis of questionnaire and photographic documentation. CONCLUSIONS: Combined microdermabrasion and cavitation peeling treatments improve the condition of seborrheic skin. PMID- 30300027 TI - Suppression of SESN1 reduces cisplatin and hyperthermia resistance through increasing reactive oxygen species (ROS) in human maxillary cancer cells. AB - INTRODUCTION: Cisplatin is used as a standard chemotherapeutic agent for head and neck cancer treatment. However, some head and neck cancers have cisplatin resistance, leading to difficulty in treatment and poor prognosis. Overcoming cisplatin resistance remains an important strategy to improve prognoses for head and neck cancer patients. OBJECTIVE: Elucidation of the mechanisms underlying cisplatin resistance can suggest novel targets to enhance the anticancer effects of cisplatin for treating head and neck cancers. MATERIAL AND METHODS: We used a cisplatin-resistant human maxillary cancer cell line, IMC-3CR to analyse the cisplatin resistance mechanisms. Cisplatin-induced genes were analysed in IMC-3CR cells using PCR array. Among the genes with expression increased by cisplatin, we specifically examined SESN1. SESN family reportedly regenerates peroxiredoxin and suppresses oxidative DNA injury by reactive oxygen species (ROS), which can be induced by chemotherapeutic agents such as cisplatin, radiation, and hyperthermia. The function of SESN1 in cisplatin resistance and ROS generation were analysed using specific RNAi. RESULTS: Results show that SESN1 was induced by cisplatin treatment in IMC-3CR cells. Suppression of SESN1 by RNAi induced apoptosis and reduced cell viability through enhancement of ROS after cisplatin treatment. Moreover, suppression of SESN1 enhanced the cell-killing effects of hyperthermia with increased ROS, but did not affect the cell-killing effects of radiation. CONCLUSIONS: This study demonstrated the participation of SESN1 in cisplatin and hyperthermia resistance of human head and neck cancers. SESN1 is a novel molecular target to overcome cisplatin resistance and hyperthermia resistance and improve head and neck cancer treatment. PMID- 30300028 TI - Predictive value of simulated SAR and temperature for changes in measured temperature after phase-amplitude steering during locoregional hyperthermia treatments. AB - INTRODUCTION: On-line adaptive hyperthermia treatment planning can be useful to suppress treatment limiting hot spots and improve tumor temperatures during locoregional hyperthermia. This requires adequate prediction of changes in heating patterns after phase-amplitude steering. We investigated the predictive value of simulated SAR and temperature for changes in measured temperature after phase-amplitude steering during locoregional hyperthermia. METHODS: All treatment sessions of 75 patients with pelvic malignancies treated between September 2013 and March 2018 were evaluated. Phase-amplitude adaptations during the 60 min steady-state period were analyzed. Treatment planning was performed using Plan2Heat, based on CT scans with (thermometry) catheters in the vagina, rectum, and bladder in situ. The predicted SAR and temperature along the thermometry tracks were extracted from the simulated distributions. Correlations between changes in average measured temperature and the simulated SAR and temperature were evaluated for single phase-amplitude steering events, unaccompanied by other (steering) actions. RESULTS: A total of 67 phase-amplitude steering events were suitable for analysis. Simulated changes in both SAR and temperature correlated with the measured temperature changes. For the vagina, R2 = 0.44 and R2 = 0.55 for SAR and temperature, respectively. For the rectum, these values were 0.53 for SAR and 0.66 for temperature. Correlations for the bladder were weaker: R2 = 0.15 and R2 = 0.14 for SAR and temperature, respectively. This can be explained by convection in the bladder fluid, unaccounted for by present treatment planning. CONCLUSION: Treatment planning can predict changes in an average temperature after phase-amplitude steering. This allows on-line support with phase-amplitude steering to optimize hyperthermia treatments. PMID- 30300029 TI - Treading the beaten path with old and new obstacles: a report from the Indian HIPEC registry. AB - BACKGROUND: The Indian HIPEC registry is a self-funded registry instituted by a group of Indian surgeons for patients with peritoneal metastases (PM) undergoing surgical treatment. This work was performed to * Evaluate outcomes of cytoreductive surgery +/- HIPEC in patients enrolled in the registry. * Identify operational problems. METHODS: A retrospective analysis of patients enrolled in the registry from March 2016 to September 2017 was performed. An online survey was performed to study the surgeons' attitudes and existing practices pertaining to the registry and identify operational problems. RESULTS: During the study period, 332 patients were enrolled in 8 participating centres. The common indication was ovarian cancer for three centres and pseudomyxoma peritonei for three others. The median PCI ranged from 3 to 23. A CC-0/1 resection was obtained in 94.7%. There was no significant difference in the morbidity (p = .25) and mortality (p = .19) rates between different centres. There was a high rate of failure-to-rescue (19.3%) patients with complications and the survival in patients with colorectal PM was inferior. A lack of dedicated personnel for data collection and entry was the main reason for only 10/43 surgeons contributing data. The other problem was the lack of complete electronic medical record systems at all centres. CONCLUSIONS: These results validate existing practices and identify country-specific problems that need to be addressed. Despite operational problems, the registry is an invaluable tool for audit and research. It shows the feasibility of fruitful collaboration between surgeons in the absence of any regulatory body or funding for the project. PMID- 30300030 TI - Post-sauna recovery enhances brain neural network relaxation and improves cognitive economy in oddball tasks. AB - OBJECTIVE: The aim of this study was to investigate the post-sauna residual consequences on brain neural network arousal, information processing and cognitive performance. METHODS: Sixteen male subjects (24 +/- 1 yr.) participated in the study. Whole-body hyperthermia was induced with Finnish sauna bathing. Before and 90 min after the sauna, resting electroencephalography (EEG) for spectral analysis and EEG event-related potentials (ERPs) during oddball tasks by two modalities (auditory and visual) were recorded. RESULTS: Sauna bathing increased rectal temperature (Tre, 37.11 +/- 0.33 degrees C to 38.84 +/- 0.32 degrees C) and heart rate (HR, 65.63 +/- 9.39 bpm to 151.0 +/- 21.8 bpm). At 90 min after the sauna, Tre (37.00 +/- 0.29 degrees C) and HR (72.1 +/- 2.80 bpm) recovered to baseline levels. An increase was found in alpha power following sauna recovery. In the visual task modality, post-sauna recovery led to enhancement in the N2 amplitude with centroparietal distribution and decreases in P3 amplitude with distribution along the frontoparietal axis for executive motor cognitive processing. In the auditory task modality, post-sauna recovery led to a decrease in P3 amplitude with a frontoparietal distribution and this change was accompanied by auditory N2 amplitude enhancement along the centroparietal distribution for non-target cognitive processing. No significant differences in task performance were found. CONCLUSION: Post-sauna recovery to normothermia led to enhanced resting neural network relaxation followed by increases in cognitive processing economy for the given oddball tasks. The auditory processing was not affected more by post-sauna recovery than was visual processing. Post-sauna recovery modifications in ERP components (stimulus processing) were insufficient to affect cognitive performance in both visual and auditory task modalities. PMID- 30300031 TI - Factors Affecting Cyclists' Chances of Success in Match-Sprint Tournaments. AB - PURPOSE:: To further the understanding of elite athlete performance in complex race environments by examining the changes in cyclists' performances between solo time trials and head-to-head racing in match-sprint tournaments. METHODS:: Analyses were derived from official results of cyclists in 61 elite international sprint tournaments (2000-2016), incorporating the results of 2060 male and 1969 female head-to-head match races. Linear mixed modelling of log-transformed qualification and finish ranks was used to determine estimates of performance predictability as intraclass correlation coefficients. Correlations between qualifying performance and final tournament rank were also calculated. Chances of winning head-to-head races were estimated adjusting for the difference in the cyclists' qualifying times. All effects were evaluated using magnitude-based inference. RESULTS:: Minor differences in predictability between qualification time-trial and final tournament rank were suggestive of more competitiveness amongst males in the overall tournament. Performance in the qualification time trial was strongly correlated with, but not fully indicative of, performance in the overall tournament. Correspondingly, being the faster qualifier had a large positive effect on the chances of winning a head-to-head race, but small substantial differences between riders remained after adjustment for time-trial differentials. CONCLUSIONS:: The present study provides further insight into how real-world competition data can be used to investigate elite-athlete performance in sports where athletes must directly interact with their opponents 1,2. For elite match-sprint cyclists, qualifying time-trial performance largely determines success in the overall tournament, but there is evidence of a consistent match race ability that modifies chances of winning head-to-head races. PMID- 30300032 TI - Comparison of CT/MRI-CEUS and US-CEUS fusion imaging techniques in the assessment of the thermal ablation of liver tumors. AB - PURPOSE: To compare the applicability of fusion imaging between contrast-enhanced ultrasound (CEUS) and computed tomography (CT) or magnetic resonance imaging (MRI) (CT/MRI-CEUS fusion imaging) and fusion imaging between CEUS and ultrasound (US-CEUS fusion imaging) in the assessment of treatment response during liver cancer ablation. METHODS: From August to December 2015, patients who underwent US guided thermal ablation of liver tumors at our hospital with available CT/MRI images were enrolled consecutively. Both CT/MRI-CEUS and US-CEUS fusion imaging were performed in all patients to evaluate treatment responses. The applicable rate, success rate of registration and duration time were recorded. Complications were monitored in the follow-up period, and CECT/MRI within three months were taken as the standard reference of technical efficacy. RESULTS: A total of 157 liver tumors (19 +/- 8 mm, range 8-55 mm) in 115 patients (54 +/- 11 years old, range 2 7~ 84 years old) were enrolled. The applicable rate of US-CEUS fusion imaging was 61.1% (96/157) because of inconspicuous lesions in US, lower than that of CT/MRI-CEUS fusion imaging (99.7% (155/157)) (p < .05). However, the success rate of registration in US-CEUS fusion imaging (93.8% (90/96)) was superior to that of CT/MRI-US fusion imaging (81.3% (126/155)) (p < .05), especially for cases combined with alternative preablation surgeries or procedures (p < .05). The technical efficacy rate was 99.3% (150/151) according to the CECT/CEMRI. CONCLUSIONS: Both CT/MRI-CEUS and US-CEUS fusion imaging are feasible means for intraprocedural immediate evaluation of treatment response for liver thermal ablation. US-CEUS fusion imaging is preferred because of its convenience and higher success rate of registration. PMID- 30300033 TI - Evidence of metabolic imbalance and oxidative stress among patients suffering from pressure ulcers. AB - BACKGROUND: Pressure ulcers (PU) are serious medical problems that involve several factors. Recent studies suggest that oxidative stress along with chronic inflammation may cause and develop PU. However, the metabolic disturbances underlying PU are not totally known. The purpose of this study is to evaluate biochemical oxidative stress markers in Tunisian patients suffering from PU. METHODS: A total of 100 adult patients with PU and 213 healthy adult controls were selected for the study. Biochemical parameters related to immune profiles, and biomarkers of the liver, kidney, and inflammatory proteins were evaluated using recently developed automated measurement methods. Oxidant-antioxidant system markers (malondialdehyde (MDA), carbonyl proteins, total antioxidant potential, total oxidant status (TOS), catalase, and glutathione-S-transferase) were studied using appropriate methods. RESULTS: Patients with PU showed, remarkably, abnormal levels of biochemical markers and relatively higher systemic oxidative stress compared to healthy subjects. This provides the first evidence that alterations in biochemical parameters and oxidative stress are features of PU. CONCLUSIONS: Understanding the signaling pathways involved in the development of PU will provide experts with additional knowledge for therapeutic strategies aimed at limiting the oxidative and inflammatory reactions in affected patients. ClinicalTrials.gov ID: NCT0257800. PMID- 30300034 TI - Genetic Relationship Between IL-6 rs1800796 Polymorphism and Susceptibility to Periodontitis. AB - BACKGROUND: There are accumulating reports for the potential role of Interleukin 6 (IL-6) rs1800796 polymorphism in the risk of periodontitis. However, distinct conclusions are observed. In this study, we have an interest in comprehensively analyzing the genetic relationship between IL-6 rs1800796 and the susceptibility to periodontitis. METHODS: We retrieved the eligible case-control studies from on line database and conducted a meta-analysis. P-value of association test, OR (odd ratios) and 95% CI (confidence interval) were calculated for the assessment of potential genetic association. RESULTS: We enrolled a total of 20 case-control studies for pooling analysis. A positive association between periodontitis cases and controls was observed in the overall meta-analysis under all genetic models (all P < 0.05, OR > 1). Similar results were detected in the "population-based, PB" and "China" subgroups (all P < 0.05, OR > 1). In the "Asian" subgroup, there is an increased periodontitis risk under the allele, homozygote, heterozygote, dominant and carrier models (all P < 0.05, OR > 1). Nevertheless, negative results were found in the "Caucasian" subgroup under all models [all P > 0.05]. In addition, a positive association between IL-6 rs1800796 and the risk of chronic periodontitis was detected under the models of allele [G vs. C], GG vs. CC, GG vs. CC+ CG and carrier [G vs. C] (all P < 0.05, OR > 1). CONCLUSION: IL-6 rs1800796 may serve as one genetic risk factor for periodontitis patients in the Asian population, especially the Chinese population. G/G genotype of IL-6 rs1800796 appears to be associated with an increased risk of chronic periodontitis. PMID- 30300035 TI - Critical Speed as a Measure of Aerobic Fitness for Male Rugby Union Players. AB - PURPOSE:: To compare critical speed (CS) derived from all-out testing (AOT) for linear and shuttle running with metrics from a graded exercise test (GXT), the Yo Yo intermittent recovery test (YYIR1), and estimation of an 800-m shuttle time trial. METHODS: Twelve male rugby players completed a GXT, YYIR1, a linear AOT, shuttle AOTs of 25- and 50-m, and an 800-m shuttle time-trial consisting of 32 x 25-m shuttles. RESULTS:: Strong linear correlations were observed between maximum oxygen uptake (VO2max) and CS (m.s-1) derived from the linear AOT (3.68 +/- 0.62, r = 0.90, p < 0.01) and 50-m shuttle AOT (3.19 +/- 0.26, r = 0.83, p < 0.01). Conversely, VO2max showed lower correlations with speeds evoking CS from 25-m AOT (2.86 +/- 0.18, r = 0.42, p = 0.18) and YY1R1 (4.36 +/- 0.11, r = 0.55, p = 0.07). The 800-m time trial (213.58 +/- 15.84 sec) was best predicted using parameters from the 25-m AOT (r = 0.93,SEE = 6.60 sec ; p < 0.001). CONCLUSION:: The AOT is a valuable method of assessing performance-specific fitness, with CS from linear and 50-m shuttle AOTs being strong predictors of VO2max, rivaling metrics from the GXT. The YYIR1 offered limited utility compared to the AOT method. PMID- 30300036 TI - Multiple antenna placement in microwave ablation assisted by a three-dimensional fusion image navigation system for hepatocellular carcinoma. AB - PURPOSE: This study was conducted to compare a three-dimensional (3D) fusion image navigation system (FINS) with ultrasound (US) for guiding percutaneous microwave ablation (PMWA) for treatment of hepatocellular carcinoma (HCC). MATERIALS AND METHODS: This is a retrospective, non-randomized, comparative study. Our team developed a 3D FINS and used it to guide PMWAs for HCCs in 19 patients (3D group) and compared the results to those of 24 PMWAs guided by US (US group). The complete ablation rate of the first session, the local tumor progression (LTP), intrahepatic recurrence and disease-free survival were compared between the groups. RESULTS: The 3D FINS was successfully applied in all 19 patients. The mean size of HCCs was 4.14 cm +/-0.95 in 3D the group and 4.07 cm +/-0.91 in the US group. Major complications were identified at 5.3% in the 3D group and 4.2% in the US group (p = .865). Average time of image fusion was 404.53 +/- 161.84 s. There were more antenna insertions in the 3D group (3.68 +/- 1.57) than in the US group (2.71 +/- 1.12) (p = .02). The complete ablation rate of the first session was higher in the 3D group (94.7%) than in the US group (62.5%) (p = .034). The mean follow-up period was 11.4 months +/-4.9 in the 3D group and 9.8 months +/-5.5 in the US group. There were no significant differences in technique efficacy rate and LTP rate between the two groups. CONCLUSIONS: The 3D FINS could be a safe, feasible and effective technique for guiding PMWA of HCC, which could help an operator improve the complete ablation rate of the first session. PMID- 30300037 TI - Training to Compete at Altitude: Natural Altitude or Simulated Live High: Train Low? AB - PURPOSE:: To compare the effects of natural altitude training and simulated live high: train low training on road race-walking performance (min), as well as treadmill threshold walking speed (km.h-1) at 4 mmol.L-1 (THRESH), and maximal oxygen consumption (VO2max), at 1380 m. METHODS:: Twenty-two elite-level, male (n = 15) and female (n = 7) race-walkers completed 14 days of: natural altitude training at 1380 m (NAT; n = 7); simulated live high; train low at 3000: 600 m (SIM; n = 7); or control conditions (600 m altitude; CON, n = 8). All pre and post-intervention testing was conducted at 1380 m, and consisted of an incremental treadmill test, completed prior to a 5 x 2 km road race-walking performance test. Differences between groups were analysed via mixed-model ANOVA and magnitude-based inferences, with a substantial change detected with >75% likelihood of exceeding the smallest worthwhile change. RESULTS:: The improvement in total performance time for the 5 x 2 km test in NAT was not substantially different to SIM, but was substantially greater (85% likely) than CON. The improvement in percentage decrement within the 5 x 2 km performance test in NAT was greater than in both SIM (93% likely) and CON (93% likely). The increase in VO2max was substantially greater (91% likely) in NAT than SIM. Improvement in THRESH was substantially greater than CON for both SIM (91% likely) and NAT (90% likely). CONCLUSIONS:: Both NAT and SIM may allow athletes to achieve reasonable acclimation prior to competition at low altitude. PMID- 30300038 TI - Training Load, Salivary Immunoglobulin A and Illness Incidence in Elite Paratriathletes. AB - PURPOSE:: To gain an exploratory insight into the relationship between training load (TL), salivary secretory immunoglobulin A (sIgA) and upper respiratory tract illness (URI) in elite paratriathletes. METHODS:: Seven paratriathletes were recruited. Athletes provided weekly saliva samples for the measurement of sIgA over 23 consecutive weeks (February - July) and a further 11 consecutive weeks (November - January). sIgA was compared to individuals' weekly training duration, external TL and internal TL, utilising time spent in pre-determined heart rate zones. Correlations were assessed via regression analyses. URI was quantified via weekly self-report symptom questionnaire. RESULTS:: There was a significant negative relationship between athletes' individual weekly training duration and sIgA secretion rate (p = 0.028) with changes in training duration accounting for 12.7% of the variance (quartiles: 0.2%, 19.2%). There was, however, no significant relationship between external or internal TL and sIgA parameters (p >= 0.104). There was no significant difference in sIgA when URI was present or not (101% vs 118% healthy median concentration; p >= 0.225); likewise, there was no difference in sIgA when URI occurred within two weeks of sampling or not (83% vs 125% healthy median concentration; p >= 0.120). CONCLUSIONS:: Paratriathletes' weekly training duration significantly affects sIgA secretion rate, yet we did not find a relationship between external or internal TL and sIgA parameters. Further, it was not possible to detect any link between sIgA and URI occurrence which throws into question the potential of using sIgA as a monitoring tool for early detection of illness. PMID- 30300039 TI - Quantitative dynamic contrast-enhanced ultrasound may help predict the outcome of hepatocellular carcinoma after microwave ablation. AB - PURPOSE: Previous studies have reported that parameters of dynamic contrast enhanced ultrasound (DCE-US) could predict prognosis of hepatocellular carcinoma (HCC) patients after antiangiogenic therapies. In this study, we aimed to investigate the correlation of DCE-US parameters and the prognosis of HCC patients after microwave ablation (MWA). MATERIALS AND METHODS: Between June 2012 and January 2018, a total of 35 HCC patients who received MWA with a curative intent were enrolled. Pre-ablation DCE-US, liver biopsy, CD34 staining, and vascular endothelial growth factor (VEGF) staining were performed. DCE-US parameters were extracted from time-intensity curves using SonoLiver software. The correlation of DCE-US parameters with histopathology results and overall survival (OS) were investigated. RESULTS: Quantitative analysis showed that IMAX, RT, TTP, and mTT of HCC were statistically different with that of reference liver parenchyma (all p < .001). Microvessel density was shown to be positively correlated with IMAX and negatively correlated with TTP (r = 0.755 and -0.647, both p < .01). Additionally, positive correlations were observed between IMAX and VEGF expression (r = 0.665, p < .01). After a median follow-up of 22 months (range 6-64 months), local recurrence was detected in three patients. Largest diameter and TTP were shown to help predict OS in univariate and multivariate analyses. CONCLUSION: DCE-US parameter may help predict the outcome of HCC patients after MWA, though further study is still needed. PMID- 30300040 TI - Advances and challenges in recombinant Mycobacterium bovis BCG-based HIV vaccine development: lessons learned. AB - INTRODUCTION: Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome, tuberculosis, and malaria are responsible for most human deaths produced by infectious diseases worldwide. Vaccination against HIV requires generation of memory T cells and neutralizing antibodies, mucosal immunity, and stimulation of an innate immune responses. In this context, the use of Mycobacterium bovis bacillus Calmette-Guerin (BCG) as a live vaccine vehicle is a promising approach for T-cell induction. Areas covered: In this review, we provide a comprehensive summary of the literature regarding immunogenicity studies in animal models performed since 2005. Furthermore, we provide expert commentary and 5-year view on how the development of potential recombinant BCG-based HIV vaccines involves careful selection of the HIV antigen, expression vectors, promoters, BCG strain, preclinical animal models, influence of preexisting immunity, and safety issues, for the rational design of recombinant BCG:HIV vaccines to prevent HIV transmission in the general population. Expert commentary: The three critical issues to be considered when developing a rBCG:HIV vaccine are codon optimization, antigen localization, and plasmid stability in vivo. The use of integrative expression vectors are likely to improve the mycobacterial vaccine stability and immunogenicity to develop not only recombinant BCG-based vaccines expressing second generation of HIV-1 immunogens but also other major pediatric pathogens to prime protective responses shortly following birth. PMID- 30300041 TI - Poxvirus-based vector systems and the potential for multi-valent and multi pathogen vaccines. AB - INTRODUCTION: With the increasing number of vaccines and vaccine-preventable diseases, the pressure to generate multi-valent and multi-pathogen vaccines grows. Combining individual established vaccines to generate single-shot formulations represents an established path, with significant ensuing public health and cost benefits. Poxvirus-based vector systems have the capacity for large recombinant payloads and have been widely used as platforms for the development of recombinant vaccines encoding multiple antigens, with considerable clinical trials activity and a number of registered and licensed products. Areas covered: Herein we discuss design strategies, production processes, safety issues, regulatory hurdles and clinical trial activities, as well as pertinent new technologies such as systems vaccinology and needle-free delivery. Literature searches used PubMed, Google Scholar and clinical trials registries, with a focus on the recombinant vaccinia-based systems, Modified Vaccinia Ankara and the recently developed Sementis Copenhagen Vector. Expert commentary: Vaccinia-based platforms show considerable promise for the development of multi-valent and multi pathogen vaccines, especially with recent developments in vector technologies and manufacturing processes. New methodologies for defining immune correlates and human challenge models may also facilitate bringing such vaccines to market. PMID- 30300042 TI - Upfront HIPEC and bevacizumab-containing adjuvant chemotherapy in advanced epithelial ovarian cancer. AB - INTRODUCTION: In advanced epithelial ovarian cancer patients, the standard of care is primary debulking surgery, followed by first-line chemotherapy often with bevacizumab addiction. In this context, some experiences have shown that a comprehensive treatment approach to surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) could improve the prognosis. OBJECTIVE: This is a study aimed to explore the feasibility of primary debulking surgery and HIPEC upfront followed by first-line therapy with bevacizumab. STUDY DESIGN: Phase II monocentric, open label, non-randomised and single-arm study. Forty patients affected by advanced ovarian cancer submitted to primary debulking surgery with HIPEC were enrolled in the study. After surgery, all patients underwent systemic chemotherapy with bevacizumab addiction. RESULTS: Complete cytoreduction (RT = 0) was achieved in all cases. Treatment-related early complications were observed in 23 patients and in 15 cases were G1-G2. Major complications were reported in 8 patients. No postoperative death was recorded. Subsequent chemotherapy was administered in all cases. Median time between surgery and first cycle of chemotherapy was 42 days (range 30-76). Concomitant bevacizumab was administered in 34 patients (85%). Maintenance with bevacizumab was feasible in 33 patients (82.5%) and its withdrawal was necessary for 1 patient (2.5%) due to G3 hypertension. CONCLUSION: Our data suggest that HIPEC can be safely introduced in the upfront therapy of advanced ovarian cancer. PMID- 30300043 TI - Sequential Pulse Compression's Effect on Blood Flow in the Lower Extremity. AB - Several interventions are available to reduce the intensity and duration of the unwanted effects (e.g. muscle soreness) associated with physical activity such as massage, compression garments, and sequential pulse compression (SPC). Such interventions aim to increase blood flow to alleviate symptoms. However, there is a lack of evidence to support the use of SPC to alter total hemoglobin concentration (THb) in active individuals. The aim of this study was to examine the acute effects of a single session of SPC on hemoglobin concentration compared to a control condition. Thirty-four physically active and healthy participants (females=12, males=22) completed the study. We randomly assigned participants to first receive the experimental (SPC) or control condition. Measures were recorded pre- and post-condition. Participants returned to the laboratory to complete the second condition >=24 hours after the first condition. Relative change in THb, oxygenated hemoglobin (O2Hb) and deoxygenated hemoglobin (HHb) measures were recorded using near-infrared spectroscopy placed on the muscle belly of the medial gastrocnemius of the dominant limb. SPC significantly increased THb (P<0.001, d=0.505) and O2Hb (P<0.001, d=0.745) change scores compared to the control condition. No statistical difference in HHb change scores were found between SPC and control conditions, but a medium effect size suggests potential biological significance (p=0.055, d=0.339). Overall, SPC increases THb to the lower extremity, and may be a viable option in the management of muscle soreness related to physical activity. PMID- 30300044 TI - Acylated ghrelin protects aorta damage post-MI via activation of eNOS and inhibition of angiotensin-converting enzyme induced activation of NAD(P)H dependent oxidase. AB - NAD(P)H dependent oxidase derived-reactive oxygen species (ROS) due to activation of the renin-angiotensin-aldosterone system (RAAS) in blood vessels postmyocardial infarction MI or during the HF leads to endothelium dysfunction and enhanced apoptosis. Acylated ghrelin (AG) is a well-reported cardioprotective and antiapoptotic agent for the heart. AG receptors are widely distributed in most of blood vessels, suggesting a role in the regulation of endothelial function and survival. This study investigated if AG can protect aorta of rats' postmyocardial infarction (MI)-induced damage and endothelial dysfunction. Adult male rats were divided into four groups of (1) Sham, (2) Sham + AG, (3) MI, and (4) MI + AG. Vehicle (normal saline) or AG (100 u/kg) was administered to rats for 21 consecutive days, after which, numerous biochemical markers were detected by blot. Both histological and electron microscope studies were carried on aortic samples from MI-induced rats. AG increased protein levels of both total and phosphorylated forms of endothelial nitric oxide synthase (eNOS and p-eNOS, respectively). Only in MI-treated rats, AG prevented the decreases in the levels of reduced glutathione (GSH) and superoxide dismutase (SOD) and lowered levels of malondialdehyde (MDA) and glutathione disulfide (GSSG). Concomitantly, it lowered the increased protein levels of angiotensin-converting enzyme (ACE), p22phox and cleaved caspase-3 and prevented the aorta histological and ultrustructural abnormalities induced by MI. PMID- 30300045 TI - How and Why School Is Important to Teenagers with Cancer: Outcomes from a Photo Elicitation Study. AB - BACKGROUND: Being diagnosed with cancer during the teenage years can be significant given that young people are at a key developmental, educational, and future-planning stage. Little is known about young people's attitude toward and engagement with school postdiagnosis, nor how this changes over time. We adopted a novel qualitative approach to examine accounts over time of young people recently diagnosed with cancer. METHODS: Twelve teenagers (13-16 years), recently diagnosed with cancer, participated in photo-elicitation interviews at three time points (~2, 6, and 9 months postdiagnosis), generating 30 interviews in total. Photo-elicitation interviews center around images that participants bring to represent key experiences and issues that matter to them. Transcripts were analyzed using interpretative phenomenological analysis. RESULTS: Seven themes were generated, representing experiences over time. Themes convey how significant school was to the young people postdiagnosis, principally because it mattered to them to maintain a normative educational pathway. Young people felt tension between wanting to be the same as their peers but feeling distinctly changed. Keeping ownership and control of their cancer story within school was challenging. Survivorship brought, for some, a legacy of missed schooling. CONCLUSION: Support for young people and reintegration plans for school need to be tailored to the young person's emerging way of understanding their cancer and recovery, and their orientation to coping. Young people need help to understand that schoolwork exemptions/extensions do not implicate academic deficiency, and how they could accept a "same but different" position as they continue to develop personally and educationally with their peers. PMID- 30300046 TI - The efficacy of lower limb screening tests in predicting PlayerLoad within a professional soccer academy. AB - CONTEXT:: Training exposure has been associated with injury epidemiology in elite youth soccer, where lower limb musculoskeletal screening is commonly used to highlight injury risk. However, there has been little consideration of the relationship between lower limb screening and the loading response to soccer activities. OBJECTIVE:: To quantify the efficacy of using screening tests to predict the loading elicited in soccer-specific activities, and to develop a hierarchical ordering of musculoskeletal screening tests to identify test redundancy and inform practice. DESIGN:: Correlational. SETTING:: Professional soccer club academy. PARTICIPANTS:: 21 elite male soccer players aged 15.7 +/- 0.9 years. INTERVENTION:: Players completed a battery of five screening tests (knee to wall, hip internal rotation, adductor squeeze, single leg hop, anterior reach), and a 25min standardised soccer session with a GPS unit placed at C7 to collect multi-planar PlayerLoad data. MAIN OUTCOME MEASURES:: Baseline data on each screening test, along with uni-axial PlayerLoad in the medio-lateral, anterio-posterior and vertical planes. RESULTS:: Stepwise hierarchical modelling of the screening tests revealed that dominant leg knee to wall distance was the most prevalent and powerful predictor of multi-planar PlayerLoad, accounting for up to 42% of variation in uni-axial loading. The adductor squeeze test was the least powerful predictor of PlayerLoad. Of note, one player who incurred a knee injury within three weeks of testing had shown a 20% reduction in knee to wall distance compared with peers, and elicited 23% greater PlayerLoad, supporting the hierarchical model. CONCLUSIONS:: There was some evidence of redundancy in the screening battery, with implications for clinical choice. Hierarchical ordering and a concurrent case study highlight dominant leg knee to wall distance as the primary predictor of multi-axial loading in soccer. This has implications for the design and interpretation of screening data in elite youth soccer. PMID- 30300047 TI - Low Doses of Caffeine: Enhancement of Physical Performance in Elite Adolescent Male Soccer Players. AB - CONTEXT:: Large doses of ~6 mg.kg-1 body mass have improved performance during intermittent running, jumping, and agility protocols. However, there are sparse data on low doses of caffeine, especially in elite adolescent soccer players. METHOD:: Fifteen elite youth soccer players (177.3+/-4.8 cm, 66.9+/-7.9 kg and 16+/-1 y) participated in the study, consuming 1, 2, or 3 mg.kg-1 caffeine in a gelatin capsule or a 2-mg.kg-1 placebo in a single-blind, randomized, crossover study design. Testing consisted of a 20-m sprint, arrowhead agility (change of direction [CoD] right or left), countermovement jump (CMJ), and Yo-Yo Intermittent Recovery Test Level-1 (Yo-Yo IR1). Post-exercise CMJ performance was assessed as participants exited the Yo-Yo IR1. Data were analyzed using a Bayesian multilevel regression model to provide explained variance and probabilities of improvement (p=%). RESULTS:: 3 mg.kg-1 caffeine presented the highest probabilities of change compared with placebo across a range of tests (mean +/- SD, p= %). Times for 20-m sprint were 3.15+/-0.10s vs 3.18+/-0.09s (p=73%), CoD-R times were 8.43+/-0.24s vs 8.55+/-0.25s (p=99%), CoD-L times were 8.44+/-0.22s vs 8.52+/-0.18s (p=85%), Yo-Yo IR1 distance was 2440+/-531m vs 2308+/-540m (p=15%), and preexercise CMJ height was 41.6+/-7.2cm vs 38+/-8.5cm (p=96%). Postexercise CMJ was higher with 3 mg.kg-1 than with placebo (42.3+/-8cm vs 36.6+/-8cm [p=100%]). Doses of 1 or 2 mg.kg-1 caffeine also demonstrated the ability to enhance performance but were task dependent. CONCLUSION:: Low doses of caffeine improve performance but are dose and task dependent. A dose of 3 mg.kg-1 caffeine improved performance across the majority of tests with potential to further improve postexercise CMJ height. PMID- 30300048 TI - The Effect of Body Checking Policy Changes on Concussion Incidence in Canadian Male Youth Ice Hockey Players: A Critically Appraised Topic. AB - CLINICAL SCENARIO:: Current studies have identified body checking as the most common cause of sports-related concussion in ice hockey across all divisions and levels. As a result, many hockey organizations, particularly in youth sports, have implemented rules making body checking to the head, face, and/or neck, illegal. Such a rule, in Canada, makes age 13 the first age in which individuals can engage in body-checking. Despite these changes, effectiveness of their implementation on the incidence of concussion in Canadian male youth ice hockey players remains unclear. CLINICAL QUESTION:: What is the effect of body checking policy changes on concussion incidence in male youth ice hockey players? SUMMARY OF KEY FINDINGS:: Two out of the three included studies reported a decrease in the incidence of concussion once a body checking policy change was implemented. The third study showed an increase; however, it is important to note that this may be due, in part, to increased awareness leading to better reporting of injuries. CLINICAL BOTTOM LINE:: Current evidence supports a relationship between body checking policy implementation and decreased concussion incidence; however, more research is needed to understand the long-term implications of policy change and the effects in other leagues. In addition, further data are needed to differentiate between increased concussion incidence resulting from concussion education efforts that may improve disclosure and increased concussion incidence as a direct result of policy changes. STRENGTH OF RECOMMENDATION:: Grade B evidence exists that policy changes regarding body checking decreases concussion incidence in youth, male ice hockey players. PMID- 30300049 TI - The Experience and Meaning of Physical Activity in Assisted Living Facility Residents. AB - Assisted living (AL) residents engage in very low levels of physical activity (PA) placing them at increased risk for mobility disability and frailty. But many residents in AL may not perceive the need to increase their PA. This study explored the experience, meaning and perceptions of PA in 20 older adults in assisted living. Factors associated with PA were also examined. Qualitative data were collected using semi-structured interviews and analyzed using Colaizzi's (1978) phenomenological methodology. Six themes were identified: PA was experienced as planned exercise, activities of daily living, and social activities based on a schedule or routine; PA meant independence and confidence in the future; residents perceived themselves as being physically active; social comparisons influenced perception of PA; personal health influenced PA; motivations and preferences influenced PA. Findings highlight the importance of residents' personal perceptions of PA and effects of the social milieu in the congregate setting on PA. PMID- 30300050 TI - Three-Dimensional Kinematics and Power Output in Elite Para-Kayakers and Elite Able-Bodied Flat-Water Kayakers. AB - Trunk, pelvis and leg movement are important for performance in sprint kayaking. Para-kayaking is a new Paralympic sport in which athletes with trunk and/or leg impairment compete in three classification groups. The purpose of this study was to identify how physical impairments impact on performance by examining: differences in three-dimensional joint range of motion (RoM) between 10 (4 females, 6 males) elite able-bodied kayakers and 41 (13 females, 28 males) elite para-kayakersfrom the three classification groups, and which joint angles were correlated with power output during high intensity kayak ergometer paddling. There were significant differences in RoM between the able-bodied kayakers and the three para-kayak groups for the shoulders (flexion, rotation: able-bodied kayakerspara kayakers) and legs (hip, knee, ankle flexion: able-bodied kayakers>para-kayakers) during paddling. Furthermore, athletes with greater impairment exhibited lower trunk and leg RoM compared to those with less impairment. Significant positive correlations were observed for both males and females between power output and peak shoulder and trunk flexion, trunk and pelvis rotation RoM and hip, knee and ankle flexion RoM. This information is important for understanding how key kinematic and kinetic variables for para-kayaking performance vary between athletes from different classification groups. PMID- 30300051 TI - Females Demonstrate Reduced Vertical Ground Reaction Forces following a 4-week Jump-Landing Feedback Intervention without Negatively Affecting Vertical Jump Performance University of Toledo, Musculoskeletal Health and Movement Science Laboratory. AB - CONTEXT:: High vertical ground reaction force (vGRF) when initiating ground contact during jump-landing is one biomechanical factor that may increase risk of anterior cruciate ligament injury. Intervention programs have been developed to decrease vGRF to reduce injury risk, yet generating high forces is still critical for performing dynamic activities such as a vertical jump task. OBJECTIVE:: To evaluate if a jump-landing feedback intervention, cueing a decrease in vGRF, would impair vertical jump performance in a separate task (Vertmax). DESIGN:: Randomized controlled trial. PATIENTS (OR OTHER PARTICIPANTS):: Forty-eight recreationally-active females (feedback: n=31, 19.63+/-1.54 years, 1.63+/-0.08cm, 58.13+/-7.84kg; control: n=15, 19.6+/-1.68 years, 1.64+/-0.05cm, 60.11+/-8.36kg) participated in this study. INTERVENTION:: Peak vGRF during a jump-landing and Vertmax were recorded at baseline and 4-weeks post. The feedback group participated in 12 sessions over the 4-week period consisting of feedback provided for 6 sets of 6 jumps off a 30cm box. The control group was instructed to return to the lab 28 days following the baseline measurements. MAIN OUTCOME MEASURES:: Change scores (post-baseline) were calculated for peak vGRF and Vertmax. Group differences were evaluated for peak vGRF and Vertmax using a Mann Whitney U test (P<0.05). RESULTS:: There were no significant differences between groups at baseline (p>0.05). The feedback group (-0.5+/-0.3N/kg) demonstrated a greater decrease in vGRF compared to the control group (0.01+/-0.3N/kg) (t(46)= 5.52, p<0.001). There were no significant differences in change in Vertmax between groups (feedback=0.9+/-2.2cm, Control=0.06+/-2.1cm; t(46)=0.46, p=0.643). CONCLUSIONS:: While the feedback intervention was effective in decreasing vGRF when landing from a jump, these participants did not demonstrate changes in vertical jump performance when assessed during a different task. Practitioners should consider implementing feedback intervention programs to reduce peak vGRF, without worry of diminished vertical jump performance. PMID- 30300052 TI - Protective Effects of beta-Carotene Against Ammonium Sulfate Toxicity: Biochemical and Histopathological Approach in Mice Model. AB - In this study, the protective role of beta-carotene against ammonium sulfate induced toxicity has been evaluated in Mus musculus var. albino mice, along with biochemical and histopathological parameters. Some biochemical parameters such as aspartate transaminase (AST), alanine transaminase (ALT), blood urea nitrogen (BUN), creatinine and oxidative stress parameters, malondialdehyde (MDA), and glutathione (GSH) levels in kidney and liver tissues were investigated. The mice were randomly divided into six groups. Group I received intraperitoneal injections of 0.9% NaCl; group II received orally administered 250 mg kg-1 bw beta-carotene, group III received orally administered 500 mg kg-1 bw beta carotene; group IV received 320 mg kg-1 bw ammonium sulfate; group V was given 250 mg kg-1 bw beta-carotene +320 mg kg-1 of bw ammonium sulfate; and group VI received orally administered 500 mg kg-1 of bw beta-carotene +320 mg kg-1 of bw ammonium sulfate. As a result, it was determined that the ammonium sulfate treatment causes significant changes in the biochemical and oxidative stress parameters and also in histological examinations. In group IV, significant increases in ALT, AST, BUN, MDA, and creatinine levels, and a significant decrease in GSH levels were observed compared with control group. In histopathological examinations, different pathological findings such as proteinaceous deposits, thickening of basement membrane, hyaline cast in kidney tissue and stellate cell, karyomegaly, and binucleated cells in liver tissue were observed. beta-carotene treatment in group V and VI ameliorated the elevated levels of liver enzymes and improved oxidative stress and histopathological findings, and so, it could be concluded that beta-carotene offered remarkable protection against ammonium sulfate-induced toxicity. PMID- 30300053 TI - Suboptimal Use of Effective Contraceptive Methods in Young Mexican Women With Breast Cancer. AB - PURPOSE: Contraceptive counseling and adherence in young women with breast cancer (BC) is a relevant issue because chemotherapy and hormonal treatment resulting in amenorrhea do not preclude unintended pregnancies. Currently, there is limited evidence from high-income countries; however, there are no studies regarding use of contraceptives in patients with BC in Mexico. This study aimed to determine the rate of contraceptive use in young Mexican women with BC during cancer treatment, characterize their contraceptive preferences, and assess contraceptive counseling by Mexican physicians. PATIENTS AND METHODS: A cross-sectional survey was conducted regarding contraceptive use and counseling among women age 40 years or younger at BC diagnosis who had completed chemotherapy in the previous 5 years or who were currently receiving long-term treatment with hormonal therapy and/or trastuzumab at a large tertiary health care facility in Mexico. RESULTS: Of a total of 104 eligible women with median age at diagnosis of 34 years, 51.1% reported using a contraceptive during chemotherapy and 45.7% reported using a contraceptive during other types of cancer treatment (hormonal therapy and trastuzumab). Of the 51 patients (49%) who were sexually active during chemotherapy, 76.5% used contraception, but only 29.4% used an effective contraceptive method. When asked about contraceptive counseling, only 16.7% recalled being advised by their health care provider. Sexually active women who received contraceptive counseling used contraceptives more often than women who were not counseled (83.3% v 22.2%). CONCLUSION: A minority of young women with BC in Mexico use effective contraception methods during cancer treatment and receive contraceptive counseling. Informing all premenopausal patients with BC about effective use of contraception methods during treatment should be an essential aspect of the supportive care of young women.

PMID- 30300055 TI - Hip abductor and adductor muscles activity patterns during landing after anterior cruciate ligament injury. AB - CONTEXT:: Hamstring and quadriceps activity adaptations are well known in individuals with anterior cruciate ligament deficiency (ACLD) and reconstructed (ACLR) to potentially compensate for knee joint instability. However, few studies have explored hip muscles activity patterns after ACL injury. OBJECTIVE:: to examine the activation characteristics of gluteus medius (GMED) and adductor longus (AL) in ACLR and ACLD subjects compared to controls. DESIGN:: case-control study. SETTING:: Athletic training room and university lab. PARTICIPANTS:: 12 healthy and 24 ACL injured (12 ACL reconstructed and 12 ACL deficit) recreationally active male volunteers. INTERVENTIONS:: Surface EMG of the GMED and AL were recorded during a single leg vertical drop landing and normalized to maximum voluntary isometric contractions (MVICs). MAIN OUTCOME MEASURES:: Preparatory and reactive muscle activity and co-activation were analyzed from 100 milliseconds prior to initial contact to 250 milliseconds post-contact. RESULTS:: During reactive activity, ACL injured (ACLR and ACLD) participants demonstrated significantly lower peak GMED activity compared to controls (F=4.33, P=0.021). In addition, ACLR participants exhibited significantly lower reactive GMED:AL co activiation muscle activity compared to controls (F=4.09, P= 0.026). CONCLUSION:: Our findings suggest neuromuscular adaptations of the hip musculature are present in people at least two years from ACL injury. GMED activation exercises should be considered in designing rehabilitation programs for ACL injured individuals. PMID- 30300056 TI - PHYSICAL EXERCISE FOR INDIVIDUALS WITH SPINAL CORD INJURY: SYSTEMATIC REVIEW BASED ON THE INTERNATIONAL CLASSIFICATION OF FUNCTIONING, DISABILITY, AND HEALTH. AB - INTRODUCTION:: Considering the reduction of physical activity performed daily in people with spinal cord injury, it is necessary to analyze the interventions based on physical exercises in order to provide recommendations based on evidence. OBJECTIVES:: To review and evaluate the literature on physical exercise interventions for individuals with SCI, based on the ICF, as well as physiological parameters for exercise prescription. METHOD:: A systematic review of the literature produced from August 2016 to February 2017 within the PubMed, EMBASE, Cochrane Library, and MEDLINE databases. Results: Two independent examiners conducted a search in which 223 articles were initially found. A third evaluator verified possible divergences and generated a final list of 25 articles that strictly met the inclusion criteria, 5 of which investigated the effects of aerobic exercise, 2 of resistance training, 2 of balance training, 12 of gait training, and 4 evaluating the combined effect of two or more forms of training. CONCLUSION:: Considering studies classified as high and moderate quality of evidence, positive effects were observed in the domains of structures and functions, in aerobic, resistance training and combined exercises, and in some studies with gait training. In the domain of activities and participation, positive effects were observed in the studies with gait training, balance training, and combined interventions. PMID- 30300057 TI - Comparing Anterior Cruciate Ligament Injury Risk Variables Between Unanticipated Cutting and Decelerating Tasks. AB - The purpose of this study was to examine the relationship between ACL injury risk factors in unanticipated cutting and decelerating. Three-dimensional kinematics and ground reaction forces were collected on eleven females (22+/-2yrs, 1.67+/ 0.08m, 68.5+/-9.8kg) during two unanticipated tasks. Paired samples t-tests were performed to compare dependent variables between tasks. Spearman rank correlation coefficients were calculated to analyze the relationship between peak internal knee adduction moment and peak anterior tibial shear force during two unanticipated tasks. Significantly greater knee abduction angles, peak knee adduction moments, and peak anterior tibial shear forces were observed during cutting (p<=0.05). A strong positive correlation existed between decelerating anterior tibial shear force and cutting anterior tibial shear force (rho=0.67), while correlations between decelerating knee adduction moment and cutting knee adduction moment and decelerating anterior tibial shear force and cutting knee adduction moment were not significant. In situations where time management is a necessity, and only one task can be evaluated, it may be more appropriate to utilize an unanticipated cutting task rather than an unanticipated deceleration task because of the increased knee adduction moment and anterior tibial shear force. These data can help future clinicians in better designing more effective ACL injury risk screening methods. PMID- 30300058 TI - Use of Physical Activity Questionnaires in People With Dementia: A Scoping Review. AB - Physical activity questionnaires are an important means to assess habitual physical activity. It remains unclear what questionnaires are used and whether they are appropriate for people with dementia who have impaired information recall but are also often largely sedentary. This scoping review aimed to identify and quantify the use of physical activity questionnaires within a dementia population. Eighteen studies met the inclusion criteria for this review. The majority of studies used questionnaires that were validated for use within an older adult population (e.g., Modified Baecke Questionnaire for the Elderly), though none had specifically been validated for use in people with dementia. Interestingly, just over half of studies (N= 10, 55.6%) adapted the questionnaires from the original validated version by allowing a proxy to provide input into the responses. Future research needs to robustly validate the use of proxy-report measures of physical activity in people with dementia. PMID- 30300059 TI - Recent ankle injury, sport participation level and tests of proprioception. AB - OBJECTIVE:: Assessing the effects of ankle injury and sport participation level on ankle proprioceptive sensitivity using a joint position reproduction (JPR) test and an inversion movement extent discrimination test. DESIGN:: Cross sectional. SETTING:: Biomechanics lab. PARTICIPANTS:: 45 student athletes aged 21 to 30 years (M 24.8 years). MAIN OUTCOME MEASURES:: Participants were tested for ankle inversion sensitivity using two devices; movement reproduction error was obtained from JPR in non-weight-bearing (N-WB) at 10 and 15 degrees of inversion, and an ankle proprioceptive sensitivity score was obtained from the active movement extent discrimination apparatus (AMEDA), representing ability to differentiate five inversion movement extents between 10.5 degrees and 14.5 degrees , with testing in both N-WB and WB. RESULTS:: For the 34 athletes with no ankle injury in the previous 12 months, the sensitivity scores achieved on the AMEDA were significantly higher (p < 0.01) than for the 11 athletes with ankle injury, and this injury effect was significantly greater in WB (p=0.013). In JPR testing, the 2.96 degrees error of reproduction for athletes with no recent ankle injury was not significantly different from the 3.36 degrees error for those with ankle injury (p=0.46). Correlation of current sport participation level with JPR showed less error for higher level performers (r = 0.49, p = 0.001), but no significant relationship to WB or N-WB AMEDA scores (both p > 0.61). WB AMEDA scores were significantly higher for athletes who had competed at a higher level of sport competition when aged <18 years (r = - 0.57, p < 0.001). CONCLUSIONS:: Previous ankle sprains affected proprioceptive scores on the WB AMEDA and N-WB AMEDA tests, indicating the sensitivity of the AMEDA movement discrimination test to the effects of ankle injury. The correlation between JPR scores and current level of sport participation suggests sensitivity of the JPR test to current ankle use. PMID- 30300060 TI - The Acute Effects of Mat Pilates on Hemodynamic and Salivary Nitrate Responses After Exercise in Postmenopausal Women. AB - The aim of study was to compare the hemodynamic and salivary responses after Mat Pilates, aerobic, resistance exercise and control. 16 normotensive postmenopausal women performed: PILATES:ten floor exercises; AEROBIC:35 minutes on the treadmill (60 to 70%of heart rate reserve); RESISTANCE: 60% of 1RM; CONTROL:no physical exercise. Blood pressure (BP) and heart rate variability (HRV) were evaluated at rest and 60 minutes after the intervention. Saliva samples were collected at rest, immediately, 30' and 60' after exercise for analysis of nitrite concentration (NO2-) and total proteins (TP). SBP, DBP and MBP AUC were lower (p<0.05) after both aerobic and resistance exercises sessions, but not the Pilates session, when compared with the control session. The NO2- concentrations in saliva were higher 60' after the end of all exercise sessions, The HRV was higher after the resistance exercise. Aerobic and resistance exercises were capable of decreasing arterial blood pressure after acute exercise. PMID- 30300061 TI - TV Viewing is Associated With All-Cause Mortality in Older Adults With Hypertension: Findings From a 6-Year Longitudinal Study. AB - The purpose of this study was to examine the longitudinal association between TV viewing and all-cause mortality in older adults with hypertension. Sedentary behavior, physical activity, hypertension and other chronic diseases were assessed by face-to-face interviews and confirmed by medical history. Mortality was reported by relatives and confirmed in medical records of the National Health System. The fully- adjusted model showed a direct association between high TV viewing time and all-cause mortality (HR: 1.65 [95% CI 1.02 - 2.68]). Women with high TV viewing were more likely to die than men. Higher TV viewing time was associated with all-cause mortality among those with diabetes and hypertension (HR: 3.54 [95% CI 1.64 - 7.66]). The findings from this longitudinal study show that higher TV viewing time is associated with higher risk for all-cause mortality among older adults with hypertension, independently of physical activity and other potential confounders. PMID- 30300062 TI - Atorvastatin induces autophagy in MDA-MB-231 breast cancer cells. AB - This article explores the effects of atorvastatin on cultured breast cancer cells. Our experiment demonstrated that atorvastatin triggered autophagy and inhibited proliferation in breast cancer cells. A CCK8 assay indicated that atorvastatin can inhibit the activity of MDA-MB-231 breast cancer cells. Western blotting results showed that atorvastatin increased the conversion of light chain 3 (LC3)-I to LC3-phosphatidylethanolamine conjugate (LC3-II). Confocal microscopy was used to reveal the appearance of a punctate structure in the cytoplasm, and electron microscopy was used to reveal the formation of double-membrane autophagosome. In conclusion, our study showed that atorvastatin may affect MDA MB-231 breast cancer cells by inducing autophagy. PMID- 30300063 TI - Clinical Breathing Mechanics Differ Based on Test and Position. AB - CONTEXT:: Altered diaphragm function is linked to decreased core stabilization, postural changes, and decreased function. Two clinical tests used to assess breathing are the hi-lo and lateral rib expansion (LRE) tests. It is currently unknown how breathing classification based on these tests differ, and how their results are affected by varying test positions. OBJECTIVE:: To compare results of breathing tests when conducted in varying test positions. DESIGN:: Prospective cross-sectional study. SETTING:: University laboratory. PARTICIPANTS:: 50 healthy adults (female=31, male=29; age=29.3+/-4.1 years; height=170.0+/-10.4cm; weight=70.7+/-15.1kg). INTERVENTION(S):: Hi-lo and LRE tests in supine, seated, standing, and half-kneeling body positions. All tests were recorded and later scored by a single examiner. A generalized estimating equations approach with breathing test and body position as factors was used for analysis. Pairwise comparison with Bonferroni correction was used to adjust for multiple tests. Statistical significance was set at p=.05, 2-tailed. MAIN OUTCOME MEASURES:: Hi lo and LRE tests were scored based on the presence or absence of abdominal excursion, lateral rib expansion, and superior rib cage migration. Following scoring, results were classified as functional or dysfunctional based on observation of these criteria. RESULTS:: A significant breathing test x test position interaction (P<0.001) was noted, as well as main effects for test (P<0.001) and test position (P<0.001).. All hi-lo test positions identified significantly more dysfunctional breathers in positions of increased stability demand (P<0.001-0.006), except between standing and half-kneeling positions (P=0.52). In the LRE test, all positions were similar (P=1.000) except for half kneeling, which was significantly different from all other positions (P<0.001). CONCLUSIONS:: The hi-lo test and LRE tests assess different breathing mechanics. Clinicians should use these tests in combination to gain a comprehensive understanding of a person's breathing pattern. The hi-lo test should be administered in multiple testing positions. PMID- 30300064 TI - Validity of the Open Barbell and Tendo Weightlifting Analyzer Systems Versus the Optotrak Certus 3D Motion Capture System for Barbell Velocity. AB - PURPOSE:: The aim of this study was to examine the validity of two linear position transducers, the Tendo Weightlifting Analyzer System (TWAS) and Open Barbell System (OBS), compared to a criterion device, the Optotrak Certus Three Dimensional Motion Capture System (OC3D). METHODS:: Twenty-five males (age: 25+/ 3yrs, height: 174.0+/-6.7cm, body mass: 89.0+/-14.7kg, squat one-repetition maximum-1RM: 175.8+/-34.7kg) with >=2yrs of resistance training experience completed a back 1RM and one set to failure at 70% of 1RM. Average (ACV) and peak (PCV) concentric velocity were recorded by all three devices during the final warm-up set, all 1RM attempts, and every repetition during the 70% set. RESULTS:: In total, 575 samples were obtained. Bland-Altman plots, Mountain plots, a one way ANOVA, standard error of measurement, and intraclass correlation coefficients were used to analyze validity. The ANOVA showed no difference (p=0.089) between devices for ACV. However, for PCV, TWAS was significantly different (i.e. inaccurate) from OC3D (p<0.001) and OBS (p=0.001), but, OBS was similar (p=0.412) to OC3D. For ACV, intraclass correlation coefficients were higher for OBS than for TWAS. Bland-Altman plots showed agreement for ACV for both devices against OC3D, but large limits of agreement for PCV for both devices. Mountain Plots showed valid ACV for both devices, however, but slightly greater ACV and PCV accuracy with OBS than TWAS. CONCLUSIONS:: Both devices may provide valid ACV measurements, but some metrics suggest more accurate ACV with OBS versus TWAS. For PCV neither device is particularly accurate, however, OBS seems to be more accurate than TWAS. PMID- 30300065 TI - Effects of Water Immersion on Squat and Split-Squat Kinematics in Older Aged Adults. AB - This study examined the effect of water immersion on trunk and lower limb kinematics during squat exercises in older aged participants. Twenty-four active older aged adults (71.4 +/- 5.4 yrs.) performed squats and split-squats on land and while partially submerged in water. Inertial sensors (100 Hz) were used to record trunk and lower-body kinematics. Water immersion increased the squat depth (squat: P=0.028, d=0.63, split-squat: P=0.005, d=0.83) and reduced the trunk flexion range (squat: P=0.006, d=0.76, split-squat: P<0.001, d=1.35) during both exercises. Additionally, water immersion increased the hip range of motion during the split-squat (P<=0.002, d=0.94). Waveform analyses also indicated differences in the timing of the movements. These results showed that aquatic-based exercise generate a different exercise outcome and appear to provide an alternative option for older aged adults, allowing these tasks to be performed in a manner that is not possible on land. PMID- 30300066 TI - Heart Rate Variability in Elite Synchronized Swimmers. AB - PURPOSE:: To determine whether heart rate variability (HRV) was correlated with other training load and training tolerance markers for monitoring the effect of a training session on elite synchronized swimmers. METHODS:: We recorded the resting HRVs (Rest) of 12 elite swimmers (mean age: 21.5+/-3.5 yrs) 3 times over 1 week with a cadence of 48 h prior to the 2015 World Swimming Championships. We continuously monitored heart rate (HR) and obtained salivary cortisol (SC) samples before and after the last training session of the week. We measured capillary blood lactate (Lapeak) 2, 4, and 8 min after the last training session and monitored recovery HRV (Rec). We assessed rate of perceived exertion (RPE) over the entire session, and we tested the association between Lapeak, SC, and RPE and relative changes (Delta%) in the natural logarithm of the root mean square successive difference of intervals (LnRMSSD). We also calculated the smallest worthwhile change (SWC) of the averaged pre and post LnRMSSD measurements. RESULTS:: There were periods of pronounced bradycardia (60.5+/-16.7 bpm) during training exercises corresponding to apneic exercise. The magnitude based inferences showed non clinically meaningful changes of LnRMSSD.Lapeak (6.8+/-2.7) was correlated positively with Delta%LnRMSSD and Delta%SC. CONCLUSIONS:: There was no change in LnRMSSD, and Lapeak, Delta%SC, and RPE indicated reduced sympathetic activation and positive adaptation to the stress imposed by the session. Isolated HRV assessment may reveal a controversial interpretation of the autonomic nervous system status or the training tolerance in elite SS athletes that are influenced by diving response. PMID- 30300067 TI - Massive hemorrhage from a unique old cesarean scar ectopic pregnancy with negative urine and serum beta-HCG: a rare case report. AB - Human chorionic gonadotropin (HCG) is an important indicator for the diagnosis of pregnancy. The authors report a unique case of cesarean scar ectopic pregnancy (CSEP) with negative urine and serum HCG levels, which was initially misdiagnosed as an intrauterine tumor despite the use of transvaginal ultrasound. Dilation and curettage was performed, which caused massive vaginal bleeding. Diagnostic hysteroscopy after uterine artery embolization and pathological examination of the surgical specimen confirmed the diagnosis of old CSEP. Postoperative follow up showed that normal menstruation restarted 2 months later. This case reminds gynecologists and obstetricians the diagnosis of CSEP should be considered, especially when there is a mass at or near the surgical scar, regardless of the HCG level. PMID- 30300068 TI - Functional hip characteristics and their relationship with ball velocity in college baseball pitchers. AB - CONTEXT:: Compared to shoulder and elbow functions, the hip functional characteristics of baseball pitchers have not been fully investigated. Therefore, little is known about the relationship between hip function and pitching performance. OBJECTIVE:: The purpose of this study was to evaluate the characteristics of hip flexibility and strength focusing on their influences on the ball velocity in baseball pitchers. DESIGN:: Descriptive laboratory study. SETTING:: Laboratory and University baseball facility. PARTICIPANTS:: Twenty three college baseball pitchers. INTERVENTIONS:: Passive hip range of motion (ROM) and isometric hip muscle strength were bilaterally measured. The pitchers threw 20 fastballs at an official pitching distance. MAIN OUTCOME MEASURES:: Bilateral hip ROM and strength in flexion, extension, abduction, adduction, and external and internal rotation; the maximal ball velocity. RESULTS:: The pivot side showed smaller hip external rotation ROM (p < 0.01), larger hip internal rotation ROM (p = 0.03), and greater hip adduction strength (p = 0.03) than the stride side. The hip extension ROM on the stride side had a negative correlation with the maximal ball velocity (r = -0.58, p < 0.01). The maximal ball velocity (135.3 +/- 4.1 km/h) positively correlated with the hip extension (r = 0.59, p < 0.01), flexion (r = 0.57, p < 0.01), abduction (r = 0.55, p < 0.01), and adduction (r = 0.55, p < 0.01) strength on the pivot leg, and the hip flexion (r = 0.53, p = 0.01), abduction (r = 0.67, p < 0.01), and adduction (r = 0.46, p = 0.03) strength on the stride leg. CONCLUSIONS:: These findings suggest that baseball pitchers do not have marked side-to-side differences in the hip flexibility and strength, and that an important fitness factor for increasing ball velocity is not the hip flexibility but the hip muscle strength of both legs. PMID- 30300069 TI - Technical and Tactical Discriminatory Factors Between Winners and Defeated Elite Karate Athletes. AB - PURPOSE:: The aim of this study was to assess the technical and tactical demands of elite karate athletes in relation to three match sequences (i.e., advantage, disadvantage, drawing) and match outcome (i.e., win/defeat). METHODS:: One hundred and twenty elite seniors (60 males and 60 females) World Karate Federation combats were analysed during two World Championships (2012 and 2014). Specific karate attributes (strategy, technique, tactic, target and effectiveness) were evaluated and classified in three sequences: advantage, disadvantage and drawing. RESULTS:: Karatekas performed more combination techniques in disadvantage sequences compared to drawing sequences (P=0.011). A higher number of timed-attack actions were reported during advantage sequences compared to drawing sequences (P=0.048). Winners of the whole combat had higher lower-limb technique rate (1.0 +/- 0.9 vs. 0.1 +/- 0.3; P=0.044) and less rate of timed-attack (0.3 +/- 0.5 vs. 0.6 +/- 1.0; P=0.030) compared to defeated karatekas during advantage- and drawing- sequences, respectively. CONCLUSIONS:: Winners used higher lower limb technique- and less timed-attack- rates compared to defeated karatekas in advantage and drawing sequences, respectively. Indeed, using lower limb technique during advantaged situations could be a powerful strategy to increase the lead. Therefore, it seems fundamental for coaches of top elite karatekas to put their athletes in simulated situation and push them to increase the use of lower limb techniques. PMID- 30300070 TI - STATIC STRETCHING INTENSITY DOES NOT INFLUENCE ACUTE RANGE OF MOTION, PASSIVE TORQUE AND MUSCLE ARCHITECTURE. AB - CONTEXT:: Although stretching exercises are commonly used in clinical and athletic practice, there is a lack of evidence regarding the methodological variables that guide the prescription of stretching programs, such as intensity. OBJECTIVE:: The aim of this study was to investigate the acute effects of different stretching intensities on the range of movement (ROM), passive torque and muscle architecture. DESIGN:: Two-group pretest-posttest design. SETTING:: Laboratory. PARTICIPANTS:: Twenty untrained men were allocated into the Low (LI) or High (HI) intensity group. MAIN OUTCOME MEASURES:: Subjects were evaluated for initial (ROMinitial) and maximum (ROMmax) discomfort angle, stiffness, viscoelastic stress relaxation (VSR), muscle fascicle length and pennation angle. RESULTS:: The ROM assessments showed significant changes, in both groups, in the pre- and post-intervention measures, both for the ROMinitial (p<0.01) and ROMmax angle (p=0.02). There were no significant differences for stiffness and VSR variables. The pennation angle and muscle fascicle length were different between the groups, but there was no significant interaction. CONCLUSION:: Performing stretching exercises at high or low intensity acutely promotes similar gains in flexibility, ie, there are short term/immediate gains in ROM, but does not modify passive torque and muscle architecture. PMID- 30300071 TI - Clinical and Biomechanical Efficacies of Mechanical Perturbation Training After Anterior Cruciate Ligament Rupture. AB - CONTEXT:: Manual perturbation training improves knee functional performance and mitigates abnormal gait in patients with anterior cruciate ligament (ACL) rupture. However, manual perturbation training is time-and labor-intensive for therapists. OBJECTIVE:: The purpose of this study was to investigate whether perturbation training administered using a mechanical device can provide effects similar to manual training on clinical measures and knee biomechanics after ACL rupture. DESIGN:: Prospective cohort (therapeutic) study. A 2x2 analysis of variance (ANOVA) was used for statistical analysis. SETTING:: A clinical and biomechanical laboratory. PATIENTS:: Eighteen Level I/II athletes with acute ACL ruptures participated in this preliminary study. INTERVENTION:: Nine patients received mechanical perturbation training on an automated mechanical device (Mechanical group) and 9 patients received manual perturbation training (Manual group). OUTCOME MEASURES:: Patients completed performance-based testing (quadriceps strength and single-legged hop tests), patient-reported questionnaires (Knee Outcome Survey- Activities of Daily Living Scale, Global Rating Score (GRS), International Knee Documentation Committee 2000 (IKDC 2000)) and 3-D gait analysis before (pre-testing) and after (post-training) training. RESULTS:: There was no significant group-by-time interaction found for all measures (p>0.18). Main effects of time were found for IKDC 2000 (pre testing:69.10+10.95, post-testing:75.14+7.19), knee excursion during weight acceptance (pre-testing: 16.01+3.99o; post-testing:17.28+3.99o) and mid-stance (pre-testing:14.78+4.13o; post-testing:16.92+4.53o) and external knee flexion moment (pre-testing:0.43+0.11 Nm/kg.m; post-testing:0.48+0.11 Nm/kg.m) (p<0.04). After accounting for pre-testing groups' differences, mechanical group scored significantly higher on triple hops (Mechanical: 96.73+6.65%; Manual: 84.97+6.83%) and 6-meter timed hops (Mechanical:102.07+9.50%; Manual: 91.21+9.42%) (p<0.047) compared to manual group. CONCLUSION:: The clinical significance of this study is the mechanical perturbation training produced effects similar to manual training, with both training methods effective at improving patients' perception of knee function and increasing knee excursion and external flexion moment during walking after acute ACL rupture. Mechanical perturbation training is a potential treatment to improve patients' functional and biomechanical outcomes after ACL rupture. PMID- 30300072 TI - Calories in Context: Conceptual Metaphors and Consumers' Perception and Use of Calorie Information. AB - The U.S. Food and Drug Administration (FDA) recently made changes to the nutrition facts label so that calories will be emphasized over all other nutrient information (U.S. Food and Drug Administration (FDA), 2016a, August 3). In light of calories' increased visibility, strategic health communicators need to understand both how individuals perceive calorie information and how calories influence consumption decisions. Therefore, a qualitative study was conducted to analyze the metaphors that structure consumers' thoughts about calorie information and food choices. In-depth interviews were conducted with 34 women from diverse racial/ethnic and socioeconomic backgrounds. Through the interviews and subsequent thematic analysis, metaphors were gathered that explained perceptions of different kinds of calories and how calories function in the diet. Five conceptual metaphors were uncovered. The metaphors individuals used varied based on their eating paradigms, and the metaphors were related to different approaches to consumption decisions. The implications of using these different calorie metaphors for translational communication interventions are further discussed. PMID- 30300073 TI - Using a mobile application to assess knee valgus in healthy and post-anterior cruciate ligament reconstruction participants. AB - CONTEXT:: Popularity of using handheld devices in clinical settings has increased, especially the use of motion analysis applications (MAA). Video-based measurement tools have been found reliable in measuring knee valgus in subjects without anterior cruciate ligament (ACL) injury. However, there is a need for validation of using a MAA to measure knee valgus in an injured population given that they may exhibit higher degrees of knee valgus. OBJECTIVE:: To examine the reliability and validity of using a MAA to measure knee valgus during functional activities used to assess return-to-sport after ACL reconstruction (ACLR). DESIGN:: Reliability and validity study. SETTING:: University laboratory. PARTICIPANTS:: Twelve ACLR participants and 20 healthy individuals. INTERVENTIONS:: Each subject performed single-leg drop landing, single-leg hop, and 90o cut with simultaneous 3-dimensional (3D) motion capture and video recording on an iPad. MAIN OUTCOME MEASURES:: Peak knee valgus during the landing phase was measured using MAA and 3D analysis. To obtain reliability, peak knee valgus was measured on 2 separate days. Reliability was determined using intra class correlation coefficients (ICCs) and standard errors of measurement (SEMs). Validity was assessed using Pearson correlation coefficients by comparing peak knee valgus between the MAA and 3D analysis. T tests were used to compare knee valgus obtained between raters, within raters, and between the MAA and 3D analysis. RESULTS:: Our data revealed excellent intra- and inter-rater reliability with low SEMs of using a MAA for both groups. Significant, moderate to large associations were found in comparing peak knee valgus between the MAA and 3D analysis. However, knee valgus was significantly different between the MAA and 3D analysis across all tasks in both groups. CONCLUSIONS:: While a MAA is reliable for measuring peak knee valgus in individuals with ACLR and healthy controls, the actual values obtained by a MAA should be viewed with caution. PMID- 30300074 TI - Renal Arterial Pseudoaneurysm After Partial Nephrectomy: Literature Review and Single-Center Analysis of Predictive Factors and Renal Functional Outcomes. AB - INTRODUCTION AND OBJECTIVE: Partial nephrectomy (PN) represents the current surgical standard for T1 tumors. Renal arterial pseudoaneurysm is a rare but potentially life-threatening complication reported after PN. The aim of this study was to identify the factors associated with the occurrence of pseudoaneurysm after PN, specifically focusing on those requiring management with selective embolization. A literature review of the topic was performed. METHODS: A retrospective review of the institutional PN database was performed from January 2011 to December 2016. Patients who underwent embolization for pseudoaneurysm represented a separated cohort to be compared with other patients (controls). Patients' and tumors' characteristics were considered. Univariable and multivariable analyses were used to test their eventual association with the occurrence of pseudoaneurysm. RESULTS: A total of 1417 cases were evaluated. At a median of 21 days (interquartile range = 10-34), 20 patients (1.4%) developed postoperative pseudoaneurysm. The majority of patients (70%) presented with gross hematuria. The clinical suspicion was confirmed by contrast-enhanced computed tomography scan with angiography. Selective embolization was performed using endovascular coils. Technical success and clinical success rates were 100% and 95%, respectively. No difference was found in percentage estimated glomerular filtration rate (eGFR) preserved between patients who underwent embolization versus controls (median 82.6% versus 86.3%, P = .35). No differences in age, baseline renal function (as assessed by glomerular filtration rate [GFR]), tumor size, and R.E.N.A.L. were found between patients who reported and did not report pseudoaneurysm. In patients who developed pseudoaneurysm, longer operative time (225.6 minutes versus 193 minutes, P = .04), and cold ischemia time (48 minutes versus 29 minutes, P = .03) were reported. CONCLUSION: In our series, the occurrence of pseudoaneurysm was associated with longer operative and cold ischemia times. In patients who underwent selective embolization, renal function remained comparable with that of controls. PMID- 30300075 TI - The Effects of HighVersus Low-Intensity Power Training on Muscle Power Outcomes in Healthy, Older Adults: A Systematic Review. AB - Power training (PT) improves muscle power in older adults, however, intensity recommendations are less clear. A narrative approach was used to compare high- versus low-intensity PT on muscle power (and function) in healthy, older adults. Searches were performed using Medline, EMBASE, CINAHL, SPORTDiscus, Ageline, and Scopus. Interventions in which older subjects (60+ years) were instructed to perform the concentric phase 'as fast as possible' were included. After searches were performed, a 3rd category of PT (moderate intensity) was included. Evidence from 27 studies (32 PT groups) showed changes in muscle power that averaged 26.8%, 33.4%, and 21.5%, respectively for high-, moderate-, and low-intensity PT, with greater changes with longer training duration and in mildly mobility-limited older adults. Function improved similarly across categories. In conclusion, both low- and high- intensity PT led to clinically significant changes in power, and are viable options for improving power and function in older adults. PMID- 30300076 TI - Contraception Update: Extended Use of Long Acting Methods, Hormonal Contraception Risks, and Over the Counter Access. AB - The clinical update serves as a brief review of recently published, high-impact, and potentially practice changing journal articles summarized for our readers. Topics include menopause, sexual dysfunction, breast health, contraception, osteoporosis, and cardiovascular disease. For this clinical update, we reviewed both reproductive and general medical journals for clinically relevant publications related to the use of contraceptive methods. We have chosen to highlight articles examining the extended use of highly effective (long-acting) methods, complications of implants, risks associated with oral combined hormonal contraceptives, and the availability of over the counter contraception. PMID- 30300077 TI - Relationship Between Obesity and Lumbar Spine Degeneration: A Cross-Sectional Study from the Fifth Korean National Health and Nutrition Examination Survey, 2010-2012. AB - BACKGROUND: Although several studies have shown that obesity affects low back pain (LBP), the relationship between degenerative lumbar spine (LSD) and obesity has not been fully investigated. This study evaluated whether obesity is independently associated with LSD in the general population. METHODS: This cross sectional study used public data from the Fifth Korean National Health and Nutrition Examination Survey (2010-2012). Subjects aged >=50 years who had completed surveys were included (3668 men and 4966 women). Obesity was classified based on the body mass index, and LSD was assessed by lumbar spine radiographs. Independent associations of obesity with LSD or LBP were determined using odds ratios (OR) adjusted by two regression models. RESULTS: The prevalence of obesity was more frequent in women than in men (38.27% vs. 33.97%, P < 0.001). Compared with normal weight women, the risk of LSD was increased in overweight and obese women following adjustments [OR = 1.227, 95% confidence interval (CI): 1.019 1.477; OR = 1.217, 95% CI: 1.024-1.446, respectively]. When obesity was subdivided, the obese II group showed higher odds for LSD in women (OR = 1.797, 95% CI: 1.287-2.510). However, obesity was not correlated with LSD in men. There was no significant association between obesity and LBP in either men or women. CONCLUSIONS: Compared with normal weight women, LSD risk was higher in overweight and obese women, especially those in the obese II subgroup. These findings suggest that maintaining normal body weight may be a preventative factor of LSD. PMID- 30300078 TI - Assessment of Subfascial Muscle/Water and Fat Accumulation in Lymphedema Patients Using Magnetic Resonance Imaging. AB - BACKGROUND: In patients with arm or leg lymphedema, more fat has been found in the epifascial compartment of the edematous limb compared to the healthy limb. However, not much is known about subfascial fat accumulation in these patients. This study aims to investigate the intramuscular and intermuscular fat and muscle/water volume in lymphedema patients. The excess of intramuscular and intermuscular fat volume was also compared to the excess epifascial fat volume, the excess limb volume, and the duration of lymphedema. METHODS AND RESULTS: Data from 13 patients (seven arm and six leg lymphedemas) were acquired using a 1.5 T magnetic resonance imaging (MRI) scanner before liposuction and at five time points (4 days, 4 weeks, 3 months, 6 months, and 1 year) after liposuction. From water-fat imaging, fat and muscle/water volumes within the intramuscular and intermuscular compartments were calculated. The relative excess volume was defined as (volume of edematous limb-volume of healthy limb)/volume of healthy limb. Elevated relative excess volumes of intramuscular and intermuscular fat were found at all time points. A decrease in the relative excess volume of muscle/water over time was found. This decrease was not correlated to the relative excess of epifascial fat volume, the relative excess of limb volume, or the duration of lymphedema. CONCLUSIONS: An excess fat volume was found in the intramuscular and intermuscular compartments in lymphedema patients. The results suggest that the subfascial compartment needs to be studied separately as no correlation between intramuscular/intermuscular fat accumulation and other measured parameters was found. PMID- 30300079 TI - Trends in Publications on Medical Cannabis from the Year 2000. AB - Widespread use of cannabis as a drug and passage of legislation on its use should lead to an increase in the number of scientific publications on cannabis. The aim of this study was to compare trends in scientific publication for papers on medical cannabis, papers on cannabis in general, and all papers between the years 2000 and 2017. A search of PubMed and Web of Science was conducted. The overall number of scientific publications in PubMed increased 2.5-fold. In contrast, the number of publications on cannabis increased 4.5-fold and the number of publications on medical cannabis increased almost 9-fold. The number of publications on medical cannabis in Web of science increased even more (10-fold). The most significant number of publications was in the field of psychiatry. In the fields of neurology and cancer treatment there was a significant increase in the years 2011-2013. There was a rise in the number of publications on children and the elderly after 2013. The specific indications with the largest number of publications were HIV (261), chronic pain (179), multiple sclerosis (118), nausea and vomiting (102), and epilepsy (88). More than half of the publications on medical cannabis originated from the United States, followed by Canada. More than 66% of the publications were original studies. The spike in the number of scientific publications on medical cannabis since 2013 is encouraging. In light of this trend the authors expect an even greater increase in the number of publications in this area in coming years. PMID- 30300080 TI - Drawing as an Encoding Tool: Memorial Benefits in Younger and Older Adults. AB - : Background/Study Context. In a recent study, drawing pictures relative to writing words at encoding has been shown to benefit later memory performance in young adults. In the current study, we sought to test whether older adults' memory might also benefit from drawing as an encoding strategy. Our prediction was that drawing would serve as a particularly effective form of environmental support at encoding as it encourages a more detailed perceptual representation. METHODS: Participants were presented 30 nouns, one at a time, and asked to either draw a picture or repeatedly write out the word, which was followed by a free recall test for all words (Experiment 1). In Experiment 2, we added an elaborative processing task in which we asked participants to list physical characteristics of the objects. In Experiment 3, we probed recognition memory for the words. RESULTS: Of the words recalled in Experiment 1, a larger proportion had been drawn than written at encoding, and this effect was larger in older relative to younger adults. In Experiment 2, we demonstrated that drawing improves memory in both younger and older adults more than does an elaborative encoding task consisting of listing descriptive characteristics of the target nouns. In Experiment 3, older and younger adults drew or wrote out words at encoding, and subsequently provided Remember-Know-New recognition memory decisions. We showed that drawing reduced age-related differences in Remember responses. CONCLUSIONS: We suggest that incorporating visuo-perceptual information into the memory trace, by drawing pictures at study, increases reliance of the memory trace on visual sensory regions, which are relatively intact in normal aging, relative to simply writing out or elaborately encoding words. Overall, results indicate that drawing is a highly valuable form of environmental support that can significantly enhance memory performance in older adults. PMID- 30300081 TI - Intra-Dermal Absorbable Suture in the Groin Incision Associated with Less Groin Surgical Site Infections than Trans-Dermal Sutures in Vascular Surgical Patients. AB - BACKGROUND: The groin surgical site is frequently infected in vascular surgical procedures. Our aim was to evaluate the relation of skin closure methods and groin incision infection after vascular operations involving femoral artery exposure. METHODS: In this retrospective patient record study, patient files of all consecutive patients admitted for a vascular procedure to the Turku University Hospital Department of Vascular Surgery during 2015-2016 were evaluated. Patients with an isolated groin surgical site because of femoral artery exposure (256) were included in the study. Patient demographics, details of the operations, and follow-up data were collected from the electronic patient data record. Statistical analyses were performed using a multi-variable model. RESULTS: Altogether, 330 groin incisions were performed for 256 patients. Of all incisions, 262 (79.4%) were closed using intra-dermal absorbable suture; trans dermal sutures were used in 68 (20.6%) incisions. Groin infections occurred in 24 (9.2%) patients after skin closure with intra-dermal absorbable suture and in 17 (25.0%) cases after trans-dermal sutures. Incisions that were closed using trans dermal sutures were 3.5 times as likely to have an infection as those closed using intra-dermal sutures (odds ratio 3.5, confidence interval 95% 1.6 to 7.6, p = 0.002). CONCLUSION: Present data suggest that groin incision closure with intra dermal absorbable suture is associated with groin incision infections compared with those incisions closed with trans-dermal sutures. PMID- 30300082 TI - Update of Recent Literature on Remotely Delivered Psychotherapy Interventions for Anxiety and Depression. AB - INTRODUCTION: Anxiety and depression are harmful to individuals suffering from these disorders, their caregivers, and the economy. Remote delivery of psychotherapy has been established as a viable alternative to traditional in person psychotherapy for treating anxiety and depression. However, literature comparing and evaluating the variety of remote delivery modalities of psychotherapy has not yet been integrated. This review examines the efficacy, practicality, and limitations of telephone, video, and online-administered psychotherapy for the treatment of anxiety and depression. METHODS: A comprehensive literature search conducted using PubMed and PsycINFO included systematic reviews, randomized controlled trials, and cost-analysis studies focused on a remote delivery method of psychotherapy for anxiety and depression. RESULTS: Overall, interventions delivered through telephone, video, and online modalities demonstrated good efficacy in treating anxiety and depression in general, and when presenting comorbid with other disorders. The literature also suggested that telehealth psychotherapy is accessible, convenient, and cost effective. However, there is less evidence for video-delivered psychotherapy for anxiety and depression compared with telephone-administered and online administered modalities. Despite this, overall, the efficacy and practical benefits of remote psychotherapy interventions in treating anxiety and depression across a diverse range of patient groups suggested that it is an appropriate alternative for those who cannot access in-person psychotherapy. CONCLUSIONS: Further research evaluating the efficacy and practical benefits of video delivered psychotherapy for anxiety and depression is much needed for patients with limited access to in-person psychological care. PMID- 30300083 TI - Hallucination in Adolescence-Or, Nora in Nowhereland Between Neurosis and Psychosis. AB - The authors present a case history in which they investigate the psychic mechanisms behind the production and function of adolescent hallucinations against the background of Freud's framework and Laplanche's concept of enigmatic messages. They conclude that these hallucinations, although to all appearance psychotic, are basically neurotic in nature, and that both their content and hallucinatory form serve to protect the defense mechanisms with which parents ward off their unconscious conflicts. PMID- 30300084 TI - On Reverie and Independence. AB - The author presents a detailed clinical discussion of his work with a forty-year old man and a ten-year-old boy in which he focuses on loss of self-object differentiation in the transference-countertransference experiences while he and these two patients were working with tyrannical internal objects (arising from in tergenerationally transmitted trauma). In both of the analytic psychotherapies, the author experiences reveries in which a benevolent paternal figure lovingly supports a child's quest for independence. These reveries are of help to the therapist in recognizing, acknowledging, and accepting the need on the part of both patients to emancipate themselves from unconscious tyrannizing internal objects. The patients had previously experienced their need for emancipation as destructive to their parents and themselves, and consequently too dangerous to attempt. PMID- 30300085 TI - Psyche Singing: Interview With Michael Eigen. AB - This interview with Michael Eigen is a conversation about doubt, faith, and three influential men, on getting too excited when reading Freud, having a revelation come in a dream, and accepting mortality. It's about starting to write and breaking things down into smaller pieces, a need to play, the madness in all of us, and the basic rhythm of breaking apart and breaking through, and of letting the psyche sing. PMID- 30300086 TI - Sexual Disgust Redux. AB - This critique of Lawrence Josephs's paper on sexual disgust offers an alternate understanding of what is meant by the term "relational." To this end, the work of Georges Bataille is appropriated toward a relational understanding of sexual disgust, both as it relates to the content of the phenomenon and as a model for investigation. The perspective adopted from Bataille is then applied to Josephs's clinical case material. The critique testifies to the need for a more expansive relational perspective, including cross-disciplinary and cross-cultural contact. PMID- 30300088 TI - Il deserto rosso. AB - The color contrast between the story the protagonist tells in Antonioni's Il deserto rosso and the rest of the film points to its oneiric significance. In it the otherwise unaccountable removal of the girl's bra is a clue to the repression of masturbation and menstruation latent in the recounted story. PMID- 30300089 TI - Effects of Resistance Training on Vascular and Hemodynamic Responses in Patients With Coronary Artery Disease. AB - PURPOSE: The purpose of this study was to determine the impact of adjunctive resistance training (RT) in aerobically trained patients with coronary artery disease on systolic blood pressure (SBP), heart rate (HR), rating of perceived exertion (RPE; using the traditional 6-to-20 scale), and rate-pressure product (RPP) responses to lifting fixed submaximal workloads. Additionally, pretest and posttest RT measures of brachial artery reactivity were obtained. METHOD: Fifteen patients with coronary artery disease (Mage = 66.1 +/- 5.1 years) who were already performing regular aerobic exercise completed an adjunctive 12-week progressive RT program. Prior to and immediately after the training period, hemodynamic responses and RPE were obtained while participants performed one set of exercises including the bicep curl (BC), shoulder press (SP), and leg press (LP) at individually determined fixed submaximal loads, using ~ 60% to 80% of estimated maximal voluntary contraction. Vascular function was assessed by flow mediated vasodilation (FMD) testing before and after training. RESULTS: Attenuated hemodynamic and RPE responses for all variables were observed. Meaningful changes were attained for RPP ([HR * SBP] / 100) during BC (106 +/- 27 mmHg * beats/min * 10-2 to 91 +/- 22 mmHg * beats/min * 10-2, d = 0.6, p < .05) and SP (102 +/- 24 mmHg * beats/min * 10-2 to 86 +/- 17 mmHg * beats/min * 10-2, d = 0.8, p < .05). Rating of perceived exertion decreased significantly during all exercises (d ranging from 1.8 to 3.1, p < .05): BC (14.3 +/- 2.6 to 9.7 +/- 1.6), SP (13.9 +/- 1.6 to 9.2 +/- 1.5), and LP (14.3 +/- 1.4 to 10.3 +/- 1.6). Peak group FMD responses were 12.8% and 10.3% dilation at pretraining and posttraining, respectively (p > .05). Five of the 15 participants showed modest improvements in their posttraining time to achieve maximum dilation from a mean of 117 s to 81 s, although this change was not statistically significant (p > .05). CONCLUSION: Among aerobically trained cardiac patients, a supplemental RT program resulted in decreased hemodynamic and RPE responses to lifting fixed submaximal workloads.

AB - BACKGROUND/PURPOSE: On a national level, African-American women have a 34% higher incidence of cervical cancer and are twice as likely to die of the disease when compared to White women. In response to the need to improve cervical cancer prevention and Pap test screening knowledge and utilization, we developed and pilot tested a 16-day SMS text message-based intervention. The CervixCheck study was designed to develop, pilot test, and evaluate the feasibility, acceptability, and initial efficacy of a spiritually-based SMS text messaging intervention aimed at increasing cervical cancer awareness and Pap test screening intention in church-attending African-American women ages 21-65. Methods/Approach: The Theory of Planned Behavior guided the development of the CervixCheck intervention. This intervention utilized a non-experimental one-group pretest-posttest design. In this article, we present findings from the pilot testing phase. Of the 52 participants at baseline, 46 completed the post-program survey. RESULTS/FINDINGS: The current study provides evidence for the early feasibility, high acceptability, and some initial efficacy of the CervixCheck intervention. There was a significant pre-post increase observed for knowledge about cervical cancer and the Pap test (p = .001) and subjective norms (p = .006). Findings post intervention also revealed that 83% of participants reported being either "satisfied" or "very satisfied" with the CervixCheck intervention and 85% found the SMS text messages either "useful" or "very useful". CONCLUSIONS/SIGNIFICANCE: A spiritually-based SMS text messaging intervention could be a culturally appropriate and cost-effective method of promoting cervical cancer early detection information to church-attending African-American women. PMID- 30300090 TI - Electrode Equivalence for Use in Bioimpedance Spectroscopy Assessment of Lymphedema. AB - BACKGROUND: Bioimpedance spectroscopy (BIS) is commonly used in the assessment and monitoring of lymphedema. This study investigated electrodes as a source of variability that could impact the accuracy of BIS in the clinic and determined if Ag/AgCl electrocardiograph (ECG) electrodes could be used as an alternative to instrument-specific electrodes. METHODS AND RESULTS: Two types of Ag/AgCl electrodes were studied: instrument-specific bioimpedance electrodes (bioimpedance) and single tab ECG electrodes (cardiac). Six areas of investigation were addressed: intrinsic electrode resistance; electrode age; drive electrode position; electrode width/surface area; concordance between cardiac and bioimpedance electrodes; and mixing electrode types and batches. Participants included women (n = 26) and men (n = 8), both with (n = 4) and without lymphedema (n = 30). Resistance (R0) of the limbs was measured and used to calculate interlimb BIS ratios. Intrinsic electrode resistance varied between batches (p <= 0.001), with cardiac electrodes recording higher resistance. Electrode age had no impact on limb resistance (p = 0.85). Drive electrode position biased limb resistance (0.1%-2.3%) and electrode size/surface area had a small (<=1%), but significant effect on limb resistance (p <= 0.001). However, calculation of interlimb BIS ratios negated the impact of these as well as any effect of mixing electrode batches and types (p = 0.15-0.96). Electrode type had no impact on arm and leg resistance, or interlimb BIS ratios (p = 0.173-0.289). CONCLUSION: Calculation of interlimb BIS ratios improves accuracy of clinical BIS. Ag/AgCl cardiac electrodes can be used as an alternative to device-specific electrodes to measure limb resistance.

PMID- 30300093 TI - Quality-of-Life Outcomes following Surgical Treatment of Meniere's Disease: A Systematic Review and Meta-analysis. AB - Objective Several surgical interventions are offered to patients with Meniere's disease (MD) who fail medical management. Although outcomes have historically been reported according to American Academy of Otolaryngology-Head and Neck Surgery guidelines, patient-reported outcome measures (PROMs) are increasingly used to evaluate treatments. This study reviews PROMs used to assess surgical treatments for MD and compares the effect of each intervention based on PROM scores. Data Sources PubMed, EMBASE, CINAHL, and Web of Science. Review Methods This is a systematic review and meta-analysis of English-language studies that reported PROMs for surgical treatments of MD. Two independent investigators assessed study eligibility, rated the quality using Methodological Index for Non Randomized Studies (MINORS), and abstracted data for comparative analysis. A random-effects model was used for meta-analysis of pooled data. Results Of 148 unique studies identified, 11 satisfied inclusion criteria. The Meniere's Disease Outcome Questionnaire (MDOQ) was the most commonly used survey. Interventions included intratympanic gentamicin, vestibular nerve section, endolymphatic sac surgery, and labyrinthectomy. Pooled analysis of 8 studies that used the MDOQ instrument demonstrated statistically significant improvements in quality of life but did not identify a difference between destructive and nondestructive procedures. Conclusion Although our review shows significant improvements in PROM scores for both destructive and nondestructive interventions, there was no significant difference noted between treatment types. We cannot draw conclusions regarding the comparative effectiveness of specific interventions, and the results do not account for placebo effects or the natural history of the disease. Further investigation with randomized controlled trials should be considered in future studies. PMID- 30300094 TI - Neuronomy, education, and outreach in neuroscience: A historical case study of Burt Green Wilder. AB - Burt Green Wilder (1841-1925) was a pioneering naturalist and anatomist who is historically known for his brain collection and for his contributions to neuroanatomical nomenclature. During his 42-year career, Wilder also used brain measurements for education and outreach, especially in regard to issues of race and gender. Additionally, Wilder influenced neuroscience education and acted as a scientific liaison to the public. For example, he designed early implementations of the sheep brain dissections that are still being conducted today, as well as likely conducted the first "Brain Day." This article reviews each of these topics, as well as others, with the aim of accurately placing Wilder in the history of neuroscience as a naturalist and anatomist who, among other achievements, pioneered the use of brain measurements for education and outreach. PMID- 30300095 TI - Thoracoscopic Treatment of Late-Presenting Congenital Diaphragmatic Hernia in Infants and Children. AB - PURPOSE: Given that the application of thoracoscopic surgery to late-presenting congenital diaphragmatic hernia (CDH) in infants and children is controversial, we summarized our experiences with patients at two medical centers and aimed to discuss the safety and feasibility of thoracoscopic repair. MATERIALS AND METHODS: A retrospective review of late-presenting CDH cases involving patients who underwent thoracoscopic repair from October 2010 to June 2017 was performed. Data, including patients' demographic characteristics, manipulative details, and postoperative complications, were extracted and analyzed. RESULTS: A total of 59 cases were included in this study. Patients ranged in age from 2 months to 8 years (mean: 18 months). Twenty-five patients presented with shortness of breath and dyspnea. Furthermore, 34 cases were found occasionally. Forty-six left-sided hernias and 13 right-sided hernias were found. Operating time ranged from 30 to 100 minutes (mean: 55 minutes), and the amount of blood loss was 3-5 mL (mean: 3.8 mL). The size of the diaphragmatic defect ranged from 2 * 2 cm to 5 * 8 cm. The chest tubes were taken out within 24 hours. The average length of postoperative hospital stay was 5.2 +/- 0.4 days (range: 4-6 days). The length of the follow-up period ranged from 3 months to 3 years (mean: 18 months), with no recurrences. CONCLUSION: Thoracoscopic repair of late-presenting CDH is a safe and efficacious technique. It can facilitate the procedure and decrease the recurrence rate by shifting the focus to operative details. The prognosis is excellent once the correct operative details are achieved. PMID- 30300096 TI - Characteristics of biochars prepared by co-pyrolysis of sewage sludge and cotton stalk intended for use as soil amendments. AB - The safe disposal and utilisation of sewage sludge can be challenging because of the potential environmental risks posed by heavy metals in the sludge. Conversion of sewage sludge and agriculture biomass into biochars that can be used to improve or remediate contaminated soils is a promising solution to this problem. In this study, biochars were produced via co-pyrolysis of sewage sludge and cotton stalk (1:1, w/w) at temperatures ranging from 300 degrees C to 600 degrees C. Then, the potential environmental risks of heavy metals and properties of the biochars were investigated. The addition of cotton stalk promoted the migration and transformation of heavy metals from bioavailable to stable fractions, which significantly reduced the potential environmental risks of heavy metals in biochars. Moreover, compared with biochars obtained via pyrolysis of sewage sludge alone, the pH values, C contents, and adsorption capacities of biochars increased, while the yields, ash contents, specific surface areas and molar H/C ratios decreased. In summary, co-pyrolysis of sewage sludge and cotton stalk is a feasible method for alleviating the potential environmental risks of heavy metals in biochars used to treat soils. PMID- 30300097 TI - A Single-Center Experience: The Diagnostic Role of Peritoneoscopy in Patients with Exudative Ascites. AB - BACKGROUND AND AIM: The causes of exudative and transudative ascites can be detected through noninvasive methods nowadays. In selected cases, peritoneoscopy could be necessary for definitive diagnosis. In this retrospective study, we aimed to present the peritoneal biopsy results of patients who had exudative ascites with unclear etiology. MATERIALS AND METHODS: A retrospective analysis was performed in 86 patients who had exudative ascites of unclear etiology. All the patients showed abnormalities of the peritoneum or greater omentum as determined by abdominal ultrasonography and underwent peritoneoscopy between January 2012 and December 2015. Patient data were obtained from hospital records. RESULTS: Eighty-six patients (male: 22; 25.6%, mean age +/- standard deviation: 57.97 +/- 15.97) who had exudative ascites of unclear etiology were included to the study. The success rate of the procedures was 100% (86/86). A specific histopathological diagnosis was made in all patients, with an overall diagnostic accuracy of 100%. Among the 86 diagnosed patients, 43 (50%) were peritonitis carcinomatosa, 21 (24.4%) were tuberculous peritonitis, 14 (16.3%) were mesothelioma, 4 (4.7%) were chronical inflammation, and 1 (1.2%) was lymphoma. Three (3.5%) patients had normal peritoneal biopsy findings. DISCUSSION: Peritoneoscopy is a safe and efficient alternative method due to its high diagnostic capacity in selected patients who have exudative ascites of unclear etiology. PMID- 30300098 TI - The Influence of Ankle Braces on Functional Performance Tests and Ankle Joint Range of Motion. AB - CONTEXT:: The lateral ankle sprain is one of the most common lower extremity injuries in sports. Previous research has found that some prophylactic ankle supports reduce the risk of recurrent ankle sprains and provide extra support to the joint. However, there is a continued concern that these supports may negatively influence performance. OBJECTIVE:: To determine if wearing an ankle brace influences athlete performance and ankle kinematics during functional performance tests (FPTs). DESIGN:: Repeated measures. SETTING:: University Gymnasium. OTHER PARTICIPANTS:: Male and female recreational or competitive athletes (n=20). INTERVENTION:: Participants performed three trials of a standing long jump, vertical jump, 40 yard sprint, and T-drill under each of the following three conditions: wearing traditional lace-up brace (brace 1), modified lace-up brace (brace 2), and no-brace. MAIN OUTCOME MEASURES:: A 2D motion capture camera was used to measure ankle range of motion (ROM) in the sagittal plane during the vertical and standing long jumps and in the frontal plane during the cutting phase of the T-drill. Performance of each test and ankle ROM were compared between each of the braced conditions. RESULTS:: Ankle braces did not influence performance in speed or agility FPTs (p>0.05). Ankle braces negatively affected performance of the standing long jump (p=0.01) and vertical jump (p=0.01). There was no significant difference between brace or no-brace conditions in ankle inversion ROM during the T-drill (p>0.05). Both brace conditions restricted ROM in the sagittal plane during the vertical and standing long jumps (p<0.05). CONCLUSIONS:: Braced conditions restricted sagittal plane ROM during the vertical jump and long jump. This decrease in ROM explains the decline in functional performance also seen during these tests. PMID- 30300099 TI - Early Low-Level Laser Therapy Improves the Passive Range of Motion and Decreases Pain in Patients with Flexor Tendon Injury. AB - BACKGROUND: To obtain the best result from flexor tendon repair surgery, proper surgical technique, appropriate materials, good rehabilitation, and patient satisfaction are essential to consider. Nevertheless, no general unique protocol still exists between researchers, for a suitable treatment plan. OBJECTIVE: The aim of the present random clinical trial (RCT) was to determine the adjuvant effect of low-level laser therapy (LLLT) on healing tendon injury in patients. MATERIALS AND METHODS: In an RCT, 97 patients (114 fingers) with sharp injury in three zones of their hands were randomly divided into LLLT and control groups, using the unequal treatment allocation approach. Thirty-nine patients (31 males and 8 females, 46 fingers) were enrolled in the LLLT group, receiving 8-10 sessions of LLLT (red and infrared lasers) over the flexor tendon repaired area. In the control group, 58 patients were included, 20 patients did not come back for follow-up, and 38 patients (29 males and 9 females, 46 fingers) participated in the study. Patients were visited in days 28 - 32 after surgery. Passive range of motion (PROM), pain severity of groups, and patient satisfaction from LLLT were all recorded. The two observers, blind to the LLLT group assessed the data independently. RESULTS: In two groups, no rupture was observed during 4 weeks postsurgery. None of the patients in the control group was able to perform the full passive flexion. There was a significant increase in PROM (t = 82.925, p = 0.000) and a significant pain reduction (t = -11.96, p = 0.000) in the LLLT group, compared with the control group. All Patients in the LLLT group were satisfied. CONCLUSIONS: LLLT is a proper adjuvant therapy in flexor tendon repair. Evidently, LLLT promotes tendon healing, alleviates the pain, and assists flexibility of soft tissue and joints, leading to the tremendous improvement in patient cooperation and compliance. PMID- 30300101 TI - The Relationship between Post-Battle Experiences and Thwarted Belongingness and Perceived Burdensomeness in Three United States Military Samples. AB - Suicide rates within the military are elevated relative to the general population; however, research suggests that many of the suicide risk factors for military personnel are similar to the suicide risk factors for civilians. Given that many military specific experiences (e.g., number of deployments) are not considered robust predictors of either suicidal ideation or behavior, it has been posited that deployment specific experiences (e.g., post-battle experiences) may be better able to explain the increased rates of suicide among military personnel. Therefore, the current study aimed to examine the relationship between post-battle experiences and perceived burdensomeness (PB), thwarted belongingness (TB), and suicidal ideation within 3 different military samples: a non-clinical sample of Army National Guard personnel, a non-clinical sample of active duty U.S. Air Force Security Forces personnel, and a clinical sample of U.S. Army personnel receiving outpatient treatment. Post-battle experiences were found to be significantly associated with TB in both non-clinical samples; however, the association between post-battle experiences and TB was non-significant within the clinical sample. Furthermore, results indicated that post-battle experiences were not significantly associated with either PB or suicidal ideation in any of the samples. These findings suggest that in non-clinical samples, post-battle experiences impact a soldier's ability to feel connected to others. Within clinical samples, results indicate that post-battle experiences may not be a direct contributor to either PB or TB. These results indicate a need for universal intervention promoting interpersonal support of military personnel and their families prior to development of further need for psychological interventions. This upstream approach may decrease further development of TB and potentially prevent suicidal desire. PMID- 30300100 TI - Does the Improvement of Position Sense Following Motor Imagery Practice Vary as a Function of Age and Time of Day? AB - The effectiveness of motor imagery practice is known to depend on age and on the ability to form motor images. In the same individual, motor imagery quality changes during the day, being better late in the morning for older adults and in the afternoon for younger adults. Does this mean that motor imagery practice should be done at specific time of the day depending on the age of participants to maximize motor learning? To examine whether the effect of motor imagery practice varies as a function of time of day and age, the authors used an arm configuration reproduction task and measured position sense accuracy before and after 135 kinesthetic motor imagery trials. Younger and older participants were randomly assigned to either a morning or an afternoon session. Data showed that the accuracy for reproducing arm configurations improved following imagery practice regardless of time of day for both younger and older adults. Moreover, the authors observed that the position sense was less accurate in the afternoon than in the morning in older participants (before and after motor imagery practice), while performance did not change during the day in younger participants. These results may have practical implications in motor learning and functional rehabilitation programs. They highlight the effectiveness of motor imagery practice for movement accuracy in both younger and older adults regardless of time of day. By contrast, they reveal that the assessment of position sense requires that the time of day be taken into account when practitioners want to report on the older patients' progress without making any mistakes. PMID- 30300102 TI - Dissemination of the Safety Planning Intervention (SPI) to University Counseling Center Clinicians to Reduce Suicide Risk among College Students. AB - OBJECTIVE: Suicide risk on college campuses remains a pervasive problem. Structural deficits in current clinical care models often result in sub-optimal treatment for suicidal students. This study reports on the feasibility, acceptability and utility of the Safety Planning Intervention (SPI), a brief, empirically-validated, clinician-administered suicide prevention intervention, in a university counseling center (UCC) setting. METHODS: Twelve university counseling center direct service staff completed a 2-hour training in SPI. Participants reported on suicide intervention practices, training needs, and confidence at baseline and 10 weeks post-training. Acceptability, utility, and frequency of SPI use were assessed at follow-up. RESULTS: All clinical staff attended the training and found it useful, reporting that confidence in managing suicide risk increased as a result. Two-thirds of staff implemented SPI least once. CONCLUSION: Results suggest that SPI is a feasible, acceptable, and useful suicide intervention tool for UCCs. PMID- 30300103 TI - Parental emotion regulation and preschoolers' prosocial behavior: The mediating roles of parental warmth and inductive discipline. AB - The potential mediating roles of parental warmth and inductive discipline on the relations of parental emotion regulation strategies to children's prosocial behavior were examined in this study. Sixty-four parents of preschoolers (50% girls) completed questionnaires assessing their own regulation practices (i.e., cognitive reappraisal, expressive suppression), parenting behaviors (i.e., parental warmth/nurturance, inductive discipline), and children's prosocial behavior (voluntary behavior intended to benefit another). The authors hypothesized that cognitive reappraisal would be positively and expressive suppression would be negatively related to parenting behaviors and children's prosocial behavior. They further hypothesized that parental warmth and inductive discipline would mediate the relations between parents' own regulation strategies and children's prosocial behavior. Results demonstrated that parental cognitive reappraisal was positively associated with warmth, and expressive suppression was negatively associated with inductive discipline and children's prosocial behavior. Parental warmth, but not inductive discipline, mediated the relations between cognitive reappraisal and children's prosocial behavior. The results highlight adults' own regulatory strategies as predictors of socialization behaviors and the potential processes for socialization of children's moral emotions and positive social development. PMID- 30300104 TI - Effects of Gain- and Loss-Framed Quit Messages on Smokers: Test of the Ability to Process the Health Message as a Moderator. AB - Health messages can emphasize the benefits of engaging in healthy behavior (gain framed) or the costs of failing to engage in it (loss-framed). Previous research revealed that gain-framed messages tend to be more effective in motivating smokers to quit. As a supplement to previous studies, we questioned whether the ability to process health messages moderates the size of the gain-frame advantage. There were two competing theoretical ideas. First, some scholars have noted that a high ability to process a health message is a necessary precondition to observe the advantage of gain-framing. Second, risk aversion-a central concept used in previous theorizing to explain the gain-frame advantage-is associated with automatic processing and automatic processing has a stronger influence on decision making under a low ability to process. We utilized a 2 (exposure to gain or loss-framed quit messages) * 2 (low or high ability to process) randomized controlled trial with a pre-post exposure change in quit intentions as the target outcome (N = 182 smokers). Although the analysis revealed the hypothesized gain frame advantage, the ability to process did not moderate the effect. We discuss the theoretical implications. PMID- 30300106 TI - The impact of different product formats on inaction inertia. AB - The inaction inertia effect describes situations in which a person rejects an opportunity after having forgone a relatively superior opportunity. This study explores whether product format (hedonic vs. utilitarian) affects the inaction inertia effect. The authors build on previous findings that show comparisons of utilitarian benefits are easier than hedonic benefits, and hedonic consumption (vs. utilitarian consumption) usually generates greater pleasure. The authors propose that people show higher inaction inertia after they have missed a superior utilitarian consumption opportunity than after they have missed a superior hedonic consumption opportunity. This prediction was tested and supported in three different experiments. Moreover, the authors found that differences in comparability between products, rather than the hedonic pleasure, explain differences in inaction inertia effects. These findings contribute to the inaction inertia literature and marketing practice. PMID- 30300105 TI - A case study on breastfeeding education in Lebanon's public medical school: exploring the potential role of social networks in medical education. AB - BACKGROUND: Limited knowledge, negative beliefs, and lack of sufficient breastfeeding promotion and support by physicians contribute to global suboptimal breastfeeding rates. Formal medical education is well-known to influence future physicians' knowledge, beliefs, and medical practice. However, less understood is the influence of social networks and processes on the exchange and diffusion of knowledge and practices related to breastfeeding. OBJECTIVES: We selected the underserved and under-supported public medical school in Lebanon to examine the social side of medical education. Our objectives were to assess knowledge, beliefs, and self-efficacy related to breastfeeding promotion and support among interns and residents. We also examined the social ecosystem surrounding these students concerning the exchange of breastfeeding knowledge. DESIGN: All data were collected during one study visit per participant. First, an interview administered structured survey was used to assess beliefs, perceived knowledge, basic breastfeeding knowledge, and self-efficacy related to breastfeeding among n = 70 medical interns and residents. Then, social network data were collected during a semi-structured interview and analyzed using an ego-network approach. All interviews were voice-recorded, transcribed, coded, and thematically analyzed. Descriptive statistics were used to analyze quantitative survey and social network results. RESULTS: Although interns and residents had positive beliefs about breastfeeding benefits, they had limited knowledge and low self efficacy related to the psychosocial and clinical aspects of breastfeeding promotion and support. They did not seem to have a well-connected professional network around breastfeeding knowledge and practices. Several tended to rely on their informal/non-professional network, such as their mothers, partners, and sisters, for knowledge and practice. CONCLUSIONS: Our work using breastfeeding as an exemplary case suggests there is a role for better attending to the beliefs of medical students as well as to the social side of medical education. Future studies can use social network theory to help identify and address influences on medical education outcomes. PMID- 30300107 TI - Fathers and Perceptions of God Play an Important Role in Psychological Adjustment Among Emerging Adults in Guatemala and the United States. AB - Interpersonal acceptance-rejection theory posits that people require parental acceptance in childhood to develop healthy psychological adjustment. People's beliefs about and their relationship with deity also influences their psychological adjustment. The purpose of the present study was to investigate how both perceived parental acceptance and a relationship with deity are related to psychological adjustment for emerging adults in Guatemala and the United States. Participants (N = 189) from Guatemala and the United States completed measures of perceived parental acceptance-rejection, images of God, attachment to God, and psychological adjustment. Results indicate that perceived paternal acceptance rejection was only a significant predictor of psychological adjustment in U.S. participants, and not in Guatemalan participants. In both samples, images of God did not predict psychological adjustment. However, an anxious attachment with God predicted psychological maladjustment for both groups. The findings suggest that two important factors to be considered by researchers, educators, and mental health professionals are adults' perceptions of their father's level of acceptance-rejection and the amount of anxiety they experience in their relationship with God. PMID- 30300108 TI - Effects of psychological distance on attraction effect. AB - The present study demonstrated that psychological distance influences the attraction effect by changing the weights of the attributes of options. Construal level theory proposes that the weight of a superordinate attribute increases with psychological distance, whereas the weight of a subordinate attribute decreases with psychological distance. The present hypothesis proposed that an asymmetrical change of weights of attributes would influence the relationship between options, and, consequently, the attraction effect would vary. The present study comprised two studies. In study 1, participants made choices among three lotteries in near and distant future conditions. Study 2 asked the participants to choose among three events in similar and dissimilar other conditions. The results showed that the choice of the asymmetrically dominating option, which was superior in superordinate attributes, increased as the psychological distance increased, whereas the choice of the asymmetrically dominating option, which was superior in subordinate attributes, decreased or stayed static. PMID- 30300109 TI - Challenges for Japanese rural home care workers in interprofessional collaboration: a qualitative study. AB - Among medical professionals, the role of home care workers is crucial in the care of patients in their homes. In Japan, however, research on the difficulties home care workers face while working in rural zones is limited. Using thematic analysis, a qualitative study was conducted with 57 home care workers in a rural area of Japan. Findings revealed the difficulties they experienced regarding the medical problems of their patients and in their relationships with other professionals. The old customs of rural medicine and the system of long-term care insurance strongly influence relationships among multiprofessionals, leading to conflict and hierarchy. PMID- 30300110 TI - Experimental Infection and Transmission Competence of Sindbis Virus in Culex torrentium and Culex pipiens Mosquitoes from Northern Sweden. AB - INTRODUCTION: Sindbis virus (SINV) is a mosquito-borne Alphavirus known to infect birds and cause intermittent outbreaks among humans in Fenno-Scandia. In Sweden, the endemic area has mainly been in central Sweden. Recently, SINV infections have emerged to northern Sweden, but the vectorial efficiency for SINV of mosquito species in this northern region has not yet been ascertained. OBJECTIVE: Mosquito larvae were sampled from the Umea region in northern Sweden and propagated in a laboratory to adult stage to investigate the infection, dissemination, and transmission efficiency of SINV in mosquitoes. MATERIALS AND METHODS: The mosquito species were identified by DNA barcoding of the cytochrome oxidase I gene. Culex torrentium was the most abundant (82.2%) followed by Culex pipiens (14.4%), Aedes annulipes (1.1%), Anopheles claviger (1.1%), Culiseta bergrothi (1.1%), or other unidentified species (1.1%). Mosquitoes were fed with SINV-infected blood and monitored for 29 days to determine the viral extrinsic incubation period. Infection and dissemination were determined by RT-qPCR screening of dissected body parts of individual mosquitoes. Viral transmission was determined from saliva collected from individual mosquitoes at 7, 14, and 29 days. SINV was detected by cell culture using BHK-21 cells, RT-qPCR, and sequencing. RESULTS: Cx. torrentium was the only mosquito species in our study that was able to transmit SINV. The overall transmission efficiency of SINV in Cx. torrentium was 6.8%. The rates of SINV infection, dissemination, and transmission in Cx. torrentium were 11%, 75%, and 83%, respectively. CONCLUSIONS: Cx. torrentium may be the key vector involved in SINV transmission in northern Sweden. PMID- 30300111 TI - Couples' employment after spousal kidney donation. AB - We used data from the United Network for Organ Sharing registry of living kidney donors and recipients to identify correlates of paid employment among couples following spousal living donation. Among such couples, post-transplant employment of both spouses (41%) was as common as employment of the donor only (41%). However, when the recipient was female, donor-only employment after transplant was more than twice as likely as compared to employment of both spouses (relative risk ratio = 2.57; p < .001). We conclude that traditional gender roles regarding paid workforce participation may be associated with the likelihood of employment after spousal kidney donation. PMID- 30300112 TI - The SIC Scale of Ageism: Confirmatory Factor Analysis, Measurement Invariance, and Revisions. AB - The present study seeks to confirm the factor structure of the succession, identity, and consumption (SIC) scale of prescriptive ageism as a modern measure of intergenerational ageism, with particular utility for institutionalized ageism and policy in health care, the workplace, and residential facilities. In addition, measurement invariance of the scale is tested for gender and racial/ethnic groups. Confirmatory factor analysis was performed on the scale as initially proposed, treating the items as categorical variables (see for treatment of Likert-type items as categorical). Modifications to the scale were explored using both theoretical and statistical criteria. Measurement invariance tests were run on both gender and racial/ethnic categories. Analyses indicated that the three-factor structure as initially proposed was validated in an undergraduate population. Minor modifications are proposed to improve the performance of the measure. Using comparative fit indices, measurement invariance was established for gender and racial/ethnic groups with mean level scale score differences discussed. PMID- 30300113 TI - Development of a Quantitative RT-PCR Assay to Differentiate Rift Valley Fever Virus Smithburn Vaccine Strain from Clone 13 Vaccine Strain. AB - A new quantitative RT-PCR assay was developed to differentiate Rift Valley fever (RVF) Smithburn vaccine strain from Clone 13 vaccine strain. The new qRT-PCR assay targeting the S segment (NSs and N gene) was tested on synthesized standard RNA and MP-12 strain viruses. The detection limit of the new qRT-PCR assay is 1 copy/MUL of NSs and N, and is able to differentiate the Smithburn vaccine strain of RVF from the Clone 13 vaccine strain. No cross-reactivity with other vector borne viruses was observed, a factor that is especially important in the Republic of Korea (ROK). To examine the performance of the qRT-PCR, intra- and inter-assay variability data were analyzed and showed high reproducibility. These results indicate that the new qRT-PCR can be used as a safe and cost-effective test. Furthermore, this result suggests the possibility of differentiation between infected and vaccinated animals diagnostic test in RVF-free countries including ROK. PMID- 30300114 TI - The Impact of Widely Publicized Suicides on Search Trends: Using Google Trends to Test the Werther and Papageno Effects. AB - OBJECTIVE: To examine the impact of widely publicized suicides on the Werther and Papageno Effects using internet search trends. METHOD: A list of widely publicized suicides from 2010 through 2018 was compiled along with dates of death for each of these individuals. Google.com/trends data was then collected for searches for "how to suicide" and "suicide prevention" for 14 days prior to a widely publicized suicide/14 days after a widely publicized suicide and 7 days prior to a widely publicized suicide/7 days after a widely publicized suicide. Comparisons were then made between these time periods for "how to suicide" and "suicide prevention." RESULTS: Some celebrities, such as Robin Williams (2014) and Aaron Hernandez (2017) were associated with increased searches. However, for many there was no increase in search trends. CONCLUSIONS: Limited support was found for the impact of widely publicized suicides on internet search trends with one case supporting a Werther Effect and one case supporting a Papageno Effect. The finding that only some celebrities were associated with increased searches may be a byproduct of the impact of celebrity status on these effects, with more prominent celebrities having the greatest impact. PMID- 30300115 TI - Social workers, nurses, or both: Who is primarily responsible for hospital discharge planning with older adults? AB - This study examines the profession primarily responsible for discharge planning in all hospitals serving older adults in Minnesota. Quantitative analyses determined that the majority of hospitals in Minnesota serving older adults are small, rural hospitals with critical access designations, are private nonprofit, and are affiliated with a health care system. Social workers are primarily responsible for discharge planning in half of the hospitals, nurses in a quarter and either a nurse/social worker team or both nurse and social worker separately in the remaining quarter. Multinomial logistic regression determined that in critical access hospitals nurses are more likely than social workers to be the profession primarily responsible for discharge planning. PMID- 30300117 TI - Reliability and Validity of the Trauma Symptom Checklist for Children and Trauma Symptom Checklist for Young Children Screeners in a Clinical Sample. AB - This study reports on the reliability and validity for two measures developed for screening of symptoms in child sexual abuse (CSA)-the Trauma Symptom Checklist for Children-Screening Form (TSCC-SF) and the Trauma Symptom Checklist for Young Children-Screening Form (TSCYC-SF). The sample of 200 children and caregivers received outpatient treatment. Internal consistencies ranged from an alpha of 0.79-0.85. Concurrent validity was demonstrated by correlations with the TSCC and TSCYC. The TSCC-SF General Trauma (GT) was only correlated Child Behavior Checklist (r = .236 for the Anxious Depressed Scale with the TSCC GT; however, all Child Behavior Checklist scales correlated with the TSCYC GT ranging from .422 to .692, and with the SC with r = .713), and the Children's Attributional and Perceptual Scale. Findings support reliability and validity reported elsewhere. The TSCC-SF and TSCYC-SF show promise for screening and triage of CSA victims in many settings. PMID- 30300116 TI - The long coding RNA AFAP1-AS1 promotes tumor cell growth and invasion in pancreatic cancer through upregulating the IGF1R oncogene via sequestration of miR-133a. AB - Long non-coding RNAs (lncRNAs) have been shown to play a significant role in the progression of many cancers, including pancreatic cancer (PC). However, the biological function and regulatory mechanisms of lncRNAs in PC remains largely unclear. The aim of this study was to identify and evaluate the potential functions of lncRNAs in PC and reveal the underlying mechanisms of their effects. Screening of published microarray data (GEO accession Nos. GSE16515 and GSE32688), revealed lncRNA AFAP1-AS1 to be one of the most upregulated lncRNAs in PC tissues. High expression of AFAP1-AS1 was correlated with advanced stages, tumor size and lymph node metastasis, as well as with poorer overall survival in patients with PC. Functionally, knockdown of AFAP1-AS1 by transfection with siRNA inhibited the proliferative and invasive capacities of PaCa-2 and SW1990 PC cells, promoted apoptosis of PC cells in vitro, and impaired in-vivo tumorigenicity. In particular, it was hypothesized that AFAP1-AS1 may act as a competitive endogenous RNA (ceRNA), effectively becoming a sink for miR-133a whose expression was found to be downregulated in PC tissues and cell lines, and which was negatively correlated with the expression of AFAP1-AS1. We also found that the IGF1R oncogene which is an important regulator of MEK/ERK signaling pathway, was positively regulated by AFAP1-AS1 through ameliorating miR-133a mediated IGF1R repression in PC tissues. Moreover, we demonstrated that knockdown of IGF1R by transfection with si-IGF1R suppressed cell proliferation, invasion and migration of PaCa-2 and SW1990 PC cells, suggesting that IGF1R may function as an oncogene in PC cells. Further investigations revealed that miR-133a reversed the biological effects of AFAP1-AS1 on PC cells. Collectively, the findings provide new evidence that AFAP1-AS1 could regulate the progression of pancreatic cancer by acting as a ceRNA, and suggest it has potential for use as both a biomarker for the early detection PC and for the development of individualized therapies for PC. PMID- 30300119 TI - Potential Mood Variation Following a Behavioral Analogue of Self-Injurious Behavior. AB - Despite increased use of behavioral analogues to identify casual mechanisms of self-injurious behavior (e.g., suicide attempts; non-suicidal self-injury), little is known about the impact on participants. The current study examined the impact of a specific behavior analogue, Self-Aggressive Paradigm (SAP), on participant affect. Community participants (n = 507) reported several affective ratings before and after completing SAP task procedures. Following the SAP, participants reported reductions in nervousness and fear and increases in calmness and anger (d = .21). Participants with a current anxiety disorder reported greater increases in happiness; those with a suicide attempt history reported greater increases in sadness. Findings demonstrate the SAP has no adverse mood effects, supporting its use in experimental research. PMID- 30300118 TI - Gestational diabetes and macrosomia among Greenlanders. Time to change diagnostic strategy? AB - : Gestational diabetes mellitus (GDM) is a serious condition associated to both maternal and offspring complications. Yet, no globally accepted consensus exists on how to test and diagnose GDM. In Greenland, the clinical criteria for testing and diagnosing GDM are adapted from Danish guidelines. The aim of this study was to estimate the prevalence of GDM among Greenlanders using both the current clinical GDM criteria and the recent WHO 2013 criteria and, further, to study the association between GDM, pre-pregnant overweight or obesity and macrosomia. A cross-sectional study of all 450 Greenlandic women who gave birth to a singleton in Nuuk within 1 year was performed. Based on an oral glucose tolerance test measuring capillary whole blood glucose, 119 women were categorised as having clinical GDM, WHO 2013 GDM or not GDM. Macrosomia defined as birth weight above 4,000 g was used as outcome variable. The prevalence of clinical GDM and WHO 2013 GDM was 0.4% (95% CI; 0-1.1) and 6.9% (95% CI; 4.5-9.2). WHO 2013 GDM, fasting blood glucose, pre-pregnant maternal overweight and obesity were associated with macrosomia. WHO 2013 GDM criteria were superior to clinical criteria in predicting macrosomia indicating that it may be time to consider the diagnostic strategy used in Greenland. Pre-pregnant overweight may also need more intensified lifestyle-intervention.

PMID- 30300121 TI - Escherichia coli mutation rates and spectra with combinations of environmental limitations. AB - Micro-organisms often face multiple stresses in natural habitats. Individual stresses are well known to influence mutation rates and the spectra of mutational types, but the extent to which multiple stresses affect the genetic variation in populations is unknown. Here we investigate pair-wise combinations of nutritional stresses in Escherichia coli to determine their effect on mutation rates and mutational types. Environmental interactions modified both the rate and spectrum of mutations in double-limited environments, but the effects were not additive or synergistic relative to single stresses. Generally, bacteria in the mixed environments behaved as if one of the two single-stress stimuli was more dominant and the genetic variation seen with every dual limitation was intermediate between known patterns with individual stresses. The composition of mutational types with double stresses was also intermediate between individual stress patterns. At least with mutations, the single stressor results available are reasonable indicators of stress-induced genetic variation in multifaceted natural habitats. With the influence of 11 conditions available on mutational patterns, we can now also see the clustering of mutational types as a function of these environments. PMID- 30300120 TI - Rubrobacter indicoceani sp. nov., a new marine actinobacterium isolated from Indian Ocean sediment. AB - A novel mesophilic marine actinobacterial strain, designated as SCSIO 08198T, was isolated from a deep-sea sediment sample collected from the Indian Ocean. The strain was Gram-stain-positive, rod-shaped and salmon pink in colour. Good growth occurred on marine agar with 1-5 % (w/v) NaCl and incubation at 28 degrees C for more than a fortnight. Sensitive to short ultraviolet radiation. Analysis of 16S rRNA gene sequences revealed that strain SCSIO 08198T had the highest similarity of 97.2 % to Rubrobacter radiotolerans DSM 5868T, and loosely related (<94.2 %) to all other species in the genus Rubrobacter. Phylogenetic analysis based on nearly complete 16S rRNA gene sequences revealed that the novel isolate shared a lineage with members of the genus Rubrobacter. The total cellular fatty acid profile was dominated by C16 : 0 12-methyl. MK-8 was the main menaquinone. The peptidoglycan type was A3alpha (l-Lys-l-Ala). The major phospholipids were diphosphatidylglycerol, phosphatidylglycerol and unidentified phospholipids. Based on the whole genome sequence analysis, the genome size is 3 078 689 bp with DNA G+C value of 63.8 mol%, including one circular chromosome and two plasmids. Based on these polyphasic data, a new species, Rubrobacterindicoceani sp. nov., is proposed, with the type strain SCSIO 08198T (=DSM 105148T=CGMCC 1.16398T). PMID- 30300122 TI - Anti-Pseudomonas activity of 3-nitro-4-phenylfuroxan. AB - Pseudomonas aeruginosa is a microorganism that is well adapted to both clinical and industrial settings, where it can form adherent communities that are difficult to eradicate. New anti-Pseudomonas compounds and strategies are necessary, as the current antimicrobial approaches for the inhibition of biofilm formation and, above all, the eradication of formed biofilms are ineffective. Compounds that belong to the furoxan family, which are well-known NO donors, have recently been shown to display anti-Pseudomonas activity. The present study investigates three furoxan compounds that are substituted at the hetero-ring with electron-withdrawing groups (NO2, CN, CONH2) for their effects on P. aeruginosa PAO1 growth and biofilm formation/dispersal. Of the furoxans tested, only 3-nitro 4-phenylfuroxan (KN455) inhibited the growth of suspended P. aeruginosa PAO1 cultures. Furthermore, KN455 inhibited the formation of both younger and older biofilms with very high yields and thus proved itself to be toxic to planktonic subpopulations. It also displayed moderate eradicating power. The activity of KN455 does not appear to be related to its capacity to release small amounts of NO. Interestingly, the isomer 4-nitro-3-phenylfuroxan (KN454), included for comparison, displayed a comparable antibiofilm rate, but did not show the same antimicrobial activity against suspended cells and planktonic subpopulations. While hypotheses as to the mechanism of action have been formulated, further investigations are necessary to shed light onto the antimicrobial activity of this furoxan. PMID- 30300123 TI - Description of a novel species of fast growing mycobacterium: Mycobacterium kyogaense sp. nov., a scotochromogenic strain received as Mycobacterium vaccae. AB - A polyphasic study was undertaken to determine the taxonomic status of a rapidly growing, scotochromogenic organism that had been received as Mycobacterium vaccaeNCTC 11659T. The organism was found to have chemotaxonomic and cultural properties in accord with its assignment to the genus Mycobacteriumand was distinguished from the type strain of Mycobacterium vaccaeand from other closely related reference strains on the basis of concatenated sequences of 16S rRNA, gyrB, hsp65, recA and rpoB genes. It was also distinguished from M. vaccaestrain DSM 43292T and from the type strain of Mycobacterium obuense, its nearest phylogenetic neighbour, on the basis of chemotaxonomic and phenotypic data and digital DNA -DNA relatedness values of 22.7 and 68.3 %, respectively. These datasets not only indicate that strain NCTC 11659T had been misclassified as M. vaccae but that it merits recognition as representing a novel species of the genus Mycobacterium. It is proposed that the organism be classified as Mycobacteriumkyogaense sp. nov. PMID- 30300124 TI - Evaluation of sexual function in women with labia minora hypertrophy: A preliminary study. AB - OBJECTIVE: To compare the sexual functions in women with labia minora hypertrophy and age-matched healthy controls. MATERIAL AND METHOD: 43 patients with labia minora hypertrophy and 30 age-matched healthy controls were enrolled in the present study. The sexual functions of the women were evaluated by using the index of female sexual function (IFSF). RESULTS: Mean ages of the patients and controls were 30.06+/-7.11 and 31.34+/-4.12 (p=0.41), respectively. Mean total IFSF scores of the patients and controls were 24.18+/-3.24 and 27.53+/-4.43 (p<0.05), respectively. The subscale scores of IFSF-lubrication, orgasm, satisfaction and pain in the patient group were significantly lower than in the control group (respectively, p<0.001, p<0.05, p<0.001 and p<0.05). There was no statistically significant difference between IFSF-arousal scores of the patient and control groups (p=0.30). The mean IFSF-desire scores of the patient group was higher than the controls (p<0.001). Labia minora hypertrophy was significantly associated with female sexual dysfunction (odds ratio [OR]=14.97, 95% confidence interval [Cl]=[3.66-61.21], p<0.001). CONCLUSION: This study suggests that patients with labia minora hypertrophy have poorer lubrication, satisfaction, pain, and orgasm scores on the IFSF scale compared to age-matched healthy controls. PMID- 30300125 TI - Association of open field behavior with blood and semen characteristics in roosters: an alternative animal model. AB - INTRODUCTION: The paucity of literature is addressed regarding the correlation between open field as an individual behavioral trait on reproductive capacity in animals. MATERIALS AND METHODS: To address this, Nine-month-old indigenous roosters were housed in individual cages. Each animal was observed twice a week for ten minutes before feeding in an open field apparatus for two weeks (7:00 12:00PM). RESULTS: Interestingly, it was found that rooster's semen characteristics were correlated with their open field behavior. On the other hand, plasma glucose level as a blood attribute was more correlated with semen characteristics. The open field monitoring also revealed that the roosters with the lowest delay to their first pace had the highest sperm forward motility and lower sperm abnormality. The heterophil to lymphocyte ratio (H:L) was found to be low when pace bout and pace numbers were 20 and 35, respectively. The negative correlation between H:L ratio and semen characteristics (live sperm percentage, sperm concentration, and membrane integrity) may be an indication of poor reproductive performance in fearful roosters with higher H:L ratio. CONCLUSIONS: The data suggested a relationship between open field behavior indices and some reproductive parameters in roosters. The results might be applicable for selection of more reproductive animals. Hence, the rooster may also be useful model for similar studies in other species. PMID- 30300126 TI - [Transsexuality and the process of sexual reassignment from the perspective of male transsex: A qualitative study]. AB - OBJECTIVE: To understand the process of sexual reassignment from the perspective of people who undergo this procedure; to know how their body image influences their day to day life and the impact on their sexuality, and to learn from transgender male experiences in order to guide the health care teams involved, so that they can provide care in a more adjusted way to actual needs. METHOD: Qualitative study with a total of 7 male transsexuals over 18 years of age, undergoing at least one surgery intervention for sexual reassignment, using data collection techniques such as individual, semi structured, open, audio recorded interviews and writing of reflective diaries. RESULTS: Decision making to undergo surgery to change their body image and sexual identity is complex. Factors influencing this decision are related to: the need to accept their own body, the experience with hormonal treatments, the relationship with the family and social context and with the partner, management of their own fears, the organization of health care services, the relationship and communication with the health care professionals, and the economic aspects. CONCLUSIONS: Both professionals and health services should consider and delve into the topic with the goal to understand the meaning of sex reassignment procedures to ensure better care for transsexualism. PMID- 30300127 TI - [Assessment of the erectile function and patients' perception of improvement in Spanish patients with erectile dysfunction]. AB - OBJECTIVE: This study has been carried out to assess the hardness of erection and the perception of improvement in erectile function with the treatments received during the last month. MATERIAL AND METHOD: Descriptive, observational, multicenter, cross-sectional study carried out in 30 urology sites in Spain. Patients diagnosed of erectile dysfunction receiving treatment during at least the last month have been enrolled. Hardness of erection has been assessed with the erection hardness score and improvement perception has been estimated with the global assessment question. RESULTS: A 63% of patients had a hardness of erection that was insufficient for penetration, but 75% of patients referred that their erectile function had improved with treatment. After adjustment for other factors, erection hardness score values were not significantly different among patients being treated with alprostadil topical cream, compared to patients being treated with the combination of phosphodiesterase 5 (PDE5) inhibitors plus alprostadil topical cream or with PDE5i other than sildenafil alone. However, patients treated with alprostadil topical cream had a significantly higher chance of referring an improvement in their erectile function compared to patients treated with PDE5i, despite the fact that they had received treatment for a shorter period of time. CONCLUSION: Hardness of erection is just another factor of erectile function, but it is not the only one influencing improvement perception by patients. PMID- 30300128 TI - [Systematic review of the subjective experience of orgasm]. AB - Orgasm is an essential component of the sexual response. Its study has generated results that point out its importance in human sexuality. The aim of the present study was to review the subjective orgasm experience, its evaluation and its association with personal, interpersonal and psychosocial variables. After conducting a literature search in major databases, we provide a total of 121 scientific articles published between 2000 and 2016, in which the subjective orgasm experience was the main variable. The analysis of the related variables shows that personal variables (for example, health and demographic factors) and interpersonal variables (for example, sexual functioning) are the most considered. To conclude, we observe the need to develop standardized instruments to evaluate specifically the subjective orgasm experience and the need to study jointly the associated variables in order to propose explanatory models of orgasm that are useful for clinical practice.

AB - The adenomatoid tumors are rare benign mesothelial lesions that in males affect mainly the epididymis. They account for over one third of paratesticular tumors, and the treatment of choice has been surgical excision. The origin in testicular parenchyma or the tunica albuginea is extremely rare. Clinical signs and imaging studies are often inconclusive in differentiate from a more common malignant intratesticular solid tumour, which can result in unnecessary orchiectomies. We present a case of adenomatoid tumor of tunica albuginea where clinical suspicion and intraoperative frozen section analysis led to a partial orchiectomy. PMID- 30300130 TI - [Psychometric validation of the Portuguese version of the Massachusetts General Hospital - Sexual Functioning Questionnaire]. AB - INTRODUCTION: Sexual dysfunctions are a high prevalence health problem, making it necessary to provide assessment instruments adapted to the Portuguese population. METHODS: The purpose of this study was to validate the Massachusetts General Hospital-Sexual Functioning Questionnaire (MGH-SFQ) for the Portuguese population. Participants in this study were 1079 Portuguese adults who completed a sociodemographic questionnaire and the MGH-SFQ. The participants' ages varied between 18 and 89 years of age (M = 29.66; SD = 13.05), and 32.6% (n = 352) were men and 67.4% (n = 727) were women. RESULTS: The Cronbach's alpha obtained was .91 and the psychometric properties of the scale were adequate. The validation of the construct was evaluated through Confirmatory Factor Analysis, setting up a suitable one-dimensional model (RMSEA = .041, CFI = .974). DISCUSSION: Taking into account the results of the psychometric validation, the sample size and the applicability of this instrument in clinical and sexological practice, we can confirm that this is a valid and reliable instrument to evaluate the sexual functioning of both Portuguese men and women.

AB - The classification of knowledge is essential for understanding between researchers and the advancement of science. In this article a brief classification of clinical research methods is presented. The advantages that researchers use the same nomenclature are recalled, which enables improved communication among researchers, facilitates replication of studies and searches in databases, and helps to establish the aspects that can affect the different research models. They are grouped into four broad categories: epidemiological articles, articles of qualitative methodology, mixed methodology articles and review articles. PMID- 30300132 TI - Long-term patient-reported satisfaction with different inflatable penile prosthesis: Comparison between AMS 700CX and Coloplast Titan. AB - INTRODUCTION: Erectile dysfunction (ED) is one of the most prevalent male sexual disorders worldwide. When conservative treatment is unsuccessful, contraindicated or causes unacceptable side effects penile prosthesis implantation is a definitive option for the management of ED. Although considered a third-line therapy, it achieves the highest satisfaction rates as compared with non-surgical treatment. Three-piece inflatable penile prothesis (IPP) represents the most sophisticated implantable device, AMS 700CXTM and Coloplast Titan(r) being the two most commonly used. Although there are several studies evaluating patient satisfaction with either model, there is little published data comparing both models. METHODS: We have compared overall patient satisfaction in 55 patients submitted to either 700CXTM or Titan(r) implantation. The Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire was used to access patient satisfaction. RESULTS: Patient mean age and follow-up time were 59.1 years and 57.9 months respectively. There was no difference in EDITS score between 700CXTM and Titan(r) IPP (77.2+/-12.1 versus 77.5+/-16.6 respectively, p=0.956). CONCLUSION: Overall patient satisfaction as assessed by EDITS questionnaire was not different between 700CXTM and Titan(r). PMID- 30300133 TI - Erectile dysfunction treated with intracavernous stem cells: A promising new therapy? AB - In the past decades, great interest has been shown in the development of new therapies for erectile dysfunction. Stem cell therapy has generated promising results in numerous preclinical trials in animal models, which is why has led to the development of the first clinical trials in humans. The main cause involved in the pathophysiology of erectile dysfunction is vascular damage related to endothelial and neuronal injury. The interest in stem cell therapy is justified by their capability to differentiate into specific damaged tissues, including endothelium and nervous tissue, and induction of the host own cell proliferation. Despite the great effort of the many studies carried out to date, knowledge about biological effects, therapeutic efficacy and safety of stem cells therapy for erectile dysfunction is still very limited. PMID- 30300134 TI - Testicular adrenal rest tumors. AB - We report a case of congenital adrenal hyperplasia in a 29 year old patient, who presented with testicular pain, bilateral testicular masses, and oligospermia. Ultrasonography confirmed, in both testis, the presence of heterogeneous and hypoechoic lesions with irregular borders and internal and peripheral vascularization. Seric tumor markers were negative. The patient was scheduled for perioperative testicular biopsy and bilateral orchiectomy. Perioperative biopsy was suggestive of testicular adrenal rest tumor and not additional procedure was performed. Treatment was initiated with high doses of glucocorticoids, decreasing the size of testicular masses and testicular pain was alleviated. PMID- 30300135 TI - Effect of anakinra, an interleukin one beta antagonist, on oxidative testicular damage induced in rats with ischemia reperfusion. AB - BACKGROUND: It has been reported in the literature that proinflammatory interleukin-1 beta (IL-1beta) is increased in cases of testicular ischemia reperfusion (I/R) damage. This information suggests that anakinra, an IL-1beta antagonist, may be effective in testicular I/R damage. OBJECTIVE: In our study, we investigated the effect of anakinra on testicular I/R damage induced in rats with torsion/detorsion. METHODS: The 50mg/kg anakinra+testicular torsion/detorsion (KTD-50) and 100mg/kg anakinra+testicular torsion/detorsion (KTD-100) groups received an intraperitoneal (i.p.) injection of 50mg/kg and 100mg/kg of anakinra, respectively. In turn, the testicular torsion/detorsion (TTD) and sham operation (SOG) groups received a single dose of distilled water as a solvent 1h before ketamine anaesthesia. After the testes of the TTD, KTD-50 and KTD-100 groups were subjected to torsion and detorsion for 4h each, the rats were killed with a high-dose anaesthesia, and their testicles were removed and evaluated through biochemical, gene expression and histopathological examinations. The results were evaluated in comparison with those of the SOG group. RESULTS: The levels of malondialdehyde (MDA), myeloperoxidase (MPO) and IL 1beta showed significant increases in the TTD group, which underwent torsion/detorsion, compared to the KTD-50, KTD-100 and SOG groups. Conversely, the levels of glutathione (tGSH), glutathione peroxidase (GPO) and glutathione s transferase (GST) were found to be significantly higher in the KTD-50, KTD-100 and SOG groups than in the TTD group. CONCLUSION: Anakinra at a 100mg/kg dose histologically suppressed better oxidative stress and tunica albuginea, germ cell, seminiferous tubule and interstitial damage in the testicular tissue compared to a 50mg/kg dose. Experimental results indicate that anakinra might be beneficial in the attenuation of testicular I/R damage. PMID- 30300137 TI - A Novel Insight into the Challenges of Diagnosing Degenerative Cervical Myelopathy using Online Symptom Checkers. AB - BACKGROUND: Degenerative Cervical Myelopathy (DCM) is a common debilitating condition resulting from degeneration of the cervical spine. Whilst decompressive surgery can halt disease progression, existing spinal cord damage is often permanent, leaving patients with lifelong disability. Early surgery improves the likelihood of recovery, yet the average time from onset of symptoms to correct diagnosis is over 2 years. The majority of delays occur initially, before and within primary care, mainly due to a lack of recognition. Symptom checkers are widely used by patients before medical consultation and can be useful for preliminary triage and diagnosis. Lack of recognition of DCM by symptom checkers may contribute to the delay in diagnosis. OBJECTIVE: The present study sought to investigate whether online symptom checkers are able to recognise relevant symptoms of DCM, to characterise the DCM differential returned, and to evaluate the diagnostic performance of its recognised symptoms. METHODS: Classical DCM symptoms were pooled from leading review articles. These symptoms were entered into the algorithms used by the top 20 symptom checker websites (N=4) (Google Search). The most widely cited symptom checker, WebMD, was used to characterise the differential diagnosis for DCM symptoms. RESULTS: 31 classical DCM symptoms were identified, of which 14 (45%) listed DCM as a differential and 3 (10%) placed DCM in the top third of the differential. The mean differential rank for motor symptoms was significantly better than for arthritic symptoms (P = .0093) and the average differential rank for all symptoms (P = .048). The symptom checker WebMD performed best at recognising DCM, placing it nearer the top of the differential list (average rank of 5.6) than both Healthline (rank of 12.9, P = .015) and Healthtools.AARP (rank of 15.5, P = .0014). On WebMD, only one combination of symptoms resulted in DCM as the primary differential: neck, shoulder and arm pain with hand weakness. 151 differential diagnoses for DCM symptoms were recorded on WebMD. Multiple sclerosis and peripheral neuropathy were the most common differentials, shortlisted for 52% and 32% of DCM symptoms respectively. CONCLUSIONS: DCM symptoms perform poorly in online symptom checkers and lead to a large differential of many other common conditions. Whilst a diagnosis becomes more likely as the number of symptoms increases, this will not support much needed earlier diagnosis. Symptom checkers remain an attractive concept with potential. Further research is required to support their optimisation. PMID- 30300136 TI - [Sexual life quality of spinal cord-injured men receiving pharmacological treatment for erectile dysfunction and their partners]. AB - OBJECTIVE: To assess the quality of sexual life reported by spinal cord-injured men treated with oral drugs for erectile dysfunction (ED) and their female partners. MATERIAL AND METHOD: Men with spinal cord injuries (SCI) complaining of ED and their female partners were evaluated using the Sexual Life Quality Questionnaire (SLQQ), a fully validated instrument in Spain. Two studies were conducted. A transversal study (1) on patients who were already on treatment with phosphodiesterase type 5 inhibitors (PDE5Is) and their partners, with 73 couples providing valid data. An additional prospective study (2) assessed SCI patients naive to PDE5Is in which both the patients and their spouses answered the SLQQ before treatment and after 3 months taking PDE5Is regularly, with 12 couples completing the study. RESULTS: The SLQQ scores of SC injured men on PDE5Is (study 1) were under the remembered pre-lesion level, with lower scores reported by those with complete lesions (P<.2 vs incomplete). Their partners' SLQQ scores were apparently similar to pre-injury times. The SLQQ scores of the patients and their partners were well correlated (r = 0.57, P<.0001), and they both reported high treatment satisfaction. Study 2: Untreated SCI patients reported very low SLQQ scores that were improved by PDE5Is treatment (P<.004), albeit without reaching the pre-injury level. A similar trend was found in their partners. Again both patients and partners reported high treatment satisfaction scores (P <.001). CONCLUSION: The sexual life quality levels of SC injured men on PDE5Is and their able-bodied spouses are well correlated. Both partners report high treatment satisfaction scores.

PMID- 30300140 TI - Galpha12 ablation exacerbates liver steatosis and obesity by suppressing USP22/SIRT1-regulated mitochondrial respiration. AB - Nonalcoholic fatty liver disease (NAFLD) arises from mitochondrial dysfunction under sustained imbalance between energy intake and expenditure, but the underlying mechanisms controlling mitochondrial respiration have not been entirely understood. Heterotrimeric G proteins converge with activated GPCRs to modulate cell-signaling pathways to maintain metabolic homeostasis. Here, we investigated the regulatory role of G protein alpha12 (Galpha12) on hepatic lipid metabolism and whole-body energy expenditure in mice. Fasting increased Galpha12 levels in mouse liver. Galpha12 ablation markedly augmented fasting-induced hepatic fat accumulation. cDNA microarray analysis from Gna12-KO liver revealed that the Galpha12-signaling pathway regulated sirtuin 1 (SIRT1) and PPARalpha, which are responsible for mitochondrial respiration. Defective induction of SIRT1 upon fasting was observed in the liver of Gna12-KO mice, which was reversed by lentivirus-mediated Galpha12 overexpression in hepatocytes. Mechanistically, Galpha12 stabilized SIRT1 protein through transcriptional induction of ubiquitin specific peptidase 22 (USP22) via HIF-1alpha increase. Galpha12 levels were markedly diminished in liver biopsies from NAFLD patients. Consistently, Gna12-KO mice fed a high-fat diet displayed greater susceptibility to diet-induced liver steatosis and obesity due to decrease in energy expenditure. Our results demonstrate that Galpha12 regulates SIRT1-dependent mitochondrial respiration through HIF-1alpha-dependent USP22 induction, identifying Galpha12 as an upstream molecule that contributes to the regulation of mitochondrial energy expenditure. PMID- 30300141 TI - Bone marrow transplantation generates T cell-dependent control of myeloma in mice. AB - Transplantation with autologous hematopoietic progenitors remains an important consolidation treatment for patients with multiple myeloma (MM) and is thought to prolong the disease plateau phase by providing intensive cytoreduction. However, transplantation induces inflammation in the context of profound lymphodepletion that may cause hitherto unexpected immunological effects. We developed preclinical models of bone marrow transplantation (BMT) for MM using Vk*MYC myeloma-bearing recipient mice and donor mice that were myeloma naive or myeloma experienced to simulate autologous transplantation. Surprisingly, we demonstrated broad induction of T cell-dependent myeloma control, most efficiently from memory T cells within myeloma-experienced grafts, but also through priming of naive T cells after BMT. CD8+ T cells from mice with controlled myeloma had a distinct T cell receptor (TCR) repertoire and higher clonotype overlap relative to myeloma free BMT recipients. Furthermore, T cell-dependent myeloma control could be adoptively transferred to secondary recipients and was myeloma cell clone specific. Interestingly, donor-derived IL-17A acted directly on myeloma cells expressing the IL-17 receptor to induce a transcriptional landscape that promoted tumor growth and immune escape. Conversely, donor IFN-gamma secretion and signaling were critical to protective immunity and were profoundly augmented by CD137 agonists. These data provide new insights into the mechanisms of action of transplantation in myeloma and provide rational approaches to improving clinical outcomes. PMID- 30300142 TI - Temporal dynamics of Wnt-dependent transcriptome reveal an oncogenic Wnt/MYC/ribosome axis. AB - Activating mutations in the Wnt pathway drive a variety of cancers, but the specific targets and pathways activated by Wnt ligands are not fully understood. To bridge this knowledge gap, we performed a comprehensive time-course analysis of Wnt-dependent signaling pathways in an orthotopic model of Wnt-addicted pancreatic cancer, using a porcupine (PORCN) inhibitor currently in clinical trials, and validated key results in additional Wnt-addicted models. The temporal analysis of the drug-perturbed transcriptome demonstrated direct and indirect regulation of more than 3,500 Wnt-activated genes (23% of the transcriptome). Regulation was both via Wnt/beta-catenin and through the modulation of protein abundance of important transcription factors, including MYC, via Wnt-dependent stabilization of proteins (Wnt/STOP). Our study identifies a central role of Wnt/beta-catenin and Wnt/STOP signaling in controlling ribosome biogenesis, a key driver of cancer proliferation. PMID- 30300144 TI - Ultrasound-Guided Cubital Tunnel Decompression in a Collegiate Swimmer: A Case Report. AB - A 19-year-old female collegiate swimmer presented to our sports medicine clinic with a history and physical examination consistent with right ulnar neuropathy at the cubital tunnel. Diagnostic ultrasound (US) revealed compression of the ulnar nerve under the cubital tunnel retinaculum (CTR) with nerve swelling proximal to the site of compression. Electrodiagnostic studies confirmed the diagnosis of a moderate to severe ulnar neuropathy at the elbow. Treatment consisted of an US guided decompression of the ulnar nerve in the cubital tunnel by cutting the CTR using a rotated stylet "v" cutting technique. The patient's symptoms resolved, and she was able to begin a swimming progression 2 weeks after the procedure. After completion of this progression, she was able to successfully resume full, unrestricted competitive collegiate swimming without return of her symptoms. To the best of our knowledge, this is the first description of an US-guided cubital tunnel decompression surgery. PMID- 30300143 TI - Concussion Burden, Recovery, and Risk Factors in Elite Youth Ice Hockey Players. AB - OBJECTIVE: To examine rates of concussion and more severe concussion (time loss of greater than 10 days) in elite 13- to 17-year-old ice hockey players. METHODS: This is a prospective cohort study (Alberta, Canada). Bantam (13-14 years) and Midget (15-17 years) male and female elite (top 20% by division of play) youth ice hockey players participated in this study. Players completed a demographic and medical history questionnaire and clinical test battery at the beginning of the season. A previously validated injury surveillance system was used to document exposure hours and injury during one season of play (8 months). Players with a suspected ice hockey-related concussion were referred to the study sport medicine physicians for assessment. Time loss from hockey participation was documented on an injury report form. RESULTS: Overall, 778 elite youth ice hockey players (659 males and 119 females; aged 13-17 years) participated in this study. In total, 143 concussions were reported. The concussion incidence rate (IR) was 17.60 concussions/100 players (95% CI, 15.09-20.44). The concussion IR was 1.31 concussions/1000 player-hours (95% CI, 1.09-1.57). Time loss of greater than 10 days was reported in 74% of cases (106/143), and 20% (n = 28) had time loss of greater than 30 days. CONCLUSIONS: Concussion is a common injury in elite youth ice hockey players. In this study population, a large proportion of concussions (74%) resulted in a time loss of greater than 10 days, possibly reflecting more conservative management or longer recovery in youth athletes.

PMID- 30300148 TI - Low-dose, short course alteplase treatment of submassive pulmonary embolism: a case series from the National Institutes of Health Clinical Center. AB - : Guidelines-recommend thrombolytic therapy for pulmonary embolism in patients with severe hemodynamic compromise and low risk of bleeding. Thrombolytics in submassive pulmonary embolism have an unfavorable risk/benefit ratio and remain controversial. Based on our experience with extensive, lower extremity thrombi, nine patients with symptomatic, submassive pulmonary embolisms (five medical, four surgical) were treated with low-dose alteplase (<10 mg/day, infused over 6 h per treatment). Alteplase was delivered by pulse spray and/or directed or undirected central venous catheters depending on clot size and location. All patients improved symptomatically and as determined objectively by pulmonary artery pressures and/or imaging, though acute benefits ranged from substantial to modest. One surgical patient required re-exploration for bleeding at the site of a recent retroperitoneal lymph node dissection. This experience may help guide the design of a randomized controlled trial to determine the safety and efficacy of low-dose alteplase for submassive pulmonary embolism. PMID- 30300149 TI - Fatal pulmonary embolism and pulmonary hemorrhage in lupus anticoagulant hypoprothrombinemia syndrome: a case report and review of literature. AB - : Lupus anticoagulant hypoprothrombinemia syndrome (LAHS) is a rare disorder characterized by development of lupus anticoagulant and antiprothrombin antibodies. The most common clinical manifestation is bleeding. Clinical management can be challenging due to the subtle balance between the bleeding and thrombotic tendencies. We report a novel case of LAHS in which the patient experienced the sequence of hemorrhage-thrombosis-hemorrhage before eventually dying of fatal pulmonary embolism and pulmonary hemorrhage. Specifically, she presented with multiple gastrointestinal bleeding episodes, followed by multifocal subdural hematomas, pulmonary embolism after normalization of prothrombin activity levels with immunosuppression, and finally with fatal pulmonary hemorrhage after enoxaparin treatment for pulmonary embolism. This case illustrates the importance of recognizing early minor bleeding episodes, and detecting specific antiprothrombin antibodies, in the diagnosis of LAHS. Furthermore, it highlights the complex challenge of normalizing prothrombin activity levels while at the same time preventing medical complications. PMID- 30300150 TI - Predictors of reliably high-value end-of-life care. AB - PURPOSE OF REVIEW: Care near the end of life is expensive and frequently not aligned with the expressed preferences of decedents, creating an opportunity to improve value, or increase quality while lowering cost. This review examines publications from 2017 and 2018 on interventions and policies associated with high-value end-of-life care. Innovations in video and web-based advance care planning are promising to improve preference-congruent care at low cost. RECENT FINDINGS: The patterns of care within hospice and in particular increased investment in patient care in hospice are shown to improve value. A meta-analysis demonstrated the role of inpatient palliative care consultations in decreasing hospitalization costs, as did several studies on inpatient palliative care units. Internationally, a range of home-based palliative care programs, implemented at the population level, demonstrated cost savings and reduced intensive care near the end of life. Finally, public policies that funded medical and long-term care and address broader inequalities were demonstrated to decrease low-value care near the end of life. SUMMARY: This review demonstrates the efficacy of a range of approaches to improve value of care at the end of life, both within the health system and across public policy sectors. PMID- 30300151 TI - Technology for improving accessibility of end-of-life care: Extension for Community Healthcare Outcomes Project. AB - PURPOSE OF REVIEW: To describe how Project ECHO works and to analyze what has been published on Project ECHO Palliative Care (Project ECHO PC) over the last 18 months. RECENT FINDINGS: Only two articles on Project ECHO PC have been published over the last 18 months: a descriptive study of experiences in seven health centers of the United States, the United Kingdom, Uruguay and India; and a quantitative and qualitative study of the impact of the teleECHO clinic on physicians and nurses in Northern Ireland, which reports a significant boost in knowledge acquisition and self-efficacy. SUMMARY: Project ECHO is an innovative telemedicine strategy, which creates learning communities, which use a standardized methodology and benefits healthcare professionals, particularly primary care providers or practitioners based on remote or rural areas.Since 2011, Project ECHO PC has been implemented in 12 health centers in 4 different countries, with greater growth in 2017. It has facilitated a wider access to professional education, improvements in clinical practice and knowledge acquisition, the development of professional curricula and more confidence and self-efficacy among healthcare professionals. Project ECHO PC is engaged in several international initiatives to aid countries with different degrees of palliative care development. PMID- 30300152 TI - Compassion in palliative care: a review. AB - PURPOSE OF REVIEW: Compassion has been recognized as a key aspect of high-quality healthcare, particularly in palliative care. This article provides a general review of the current understanding of compassion in palliative care and summarizes emergent compassionate initiatives in palliative care at three interdependent levels: compassion for patients, compassion in healthcare professionals, and compassionate communities at the end of life. RECENT FINDINGS: Compassion is a constructive response to suffering that enhances treatment outcomes, fosters the dignity of the recipient, and provides self-care for the giver. Patients and healthcare professionals value compassion and perceive a general lack of compassion in healthcare systems. Compassion for patients and for professionals' self-care can be trained and implemented top-down (institutional policies) and bottom-up (compassion training). 'Compassionate communities' is an important emerging movement that complements regular healthcare and social services with a community-level approach to offer compassionate care for people at the end of life. SUMMARY: Compassion can be enhanced through diverse methodologies at the organizational, professional, and community levels. This enhancement of compassion has the potential to improve quality of palliative care treatments, enhance healthcare providers' satisfaction, and reduce healthcare costs. PMID- 30300153 TI - Palliative care teaching shapes medical undergraduate students' professional development: a scoping review. AB - PURPOSE OF REVIEW: The aim of this review is to understand how palliative care teaching (PCT) as a patient-centered learning model, influences medical undergraduate students' professional development. RECENT FINDINGS: To study PCT medical undergraduate students' learning experiences, we have employed the medical teaching concept, 'hidden curriculum,' as a way of describing attitudes and behavior conveyed implicitly by palliative care educators. Fifteen studies were selected: ten of those studies used a qualitative approach; two are theoretical explanations of the topic explored, one guideline, one review and just one quantitative study, made up the review. Medical undergraduate students reported that after PCT, they felt they had acquired better attitudes for effective integration with the patient, such as empathy or holistic care; ethical principles, such as respect or humanization of their clinical practice; and commitment to an improvement in competences, such as self-awareness or self esteem. They also reported improved behavior in effective integration with patients, such as communication, caring for patients' families, and when addressing psychosocial, cultural and spiritual aspects; their commitment to improvement in competences, such as dealing with emotions and uncertainty; they learned team work as an effective way to interact within the health system; and to become more reliable, making themselves more available and dedicating enough time to each patient. SUMMARY: PCT seems to be an effective way of fostering medical undergraduate students' patient-centered professional development. PMID- 30300154 TI - The role of day care in supporting older people living with long-term conditions. AB - PURPOSE OF REVIEW: For older people with long-term conditions, regular structured activities within a community setting meeting others are thought to improve well being and quality of life. Historically local authority-run day care centres were widely available, but austerity measures have meant that in many areas, such provision has been markedly reduced and different models of day care services are being developed. There is little known about outcomes of day care provision for older people with long-term conditions. RECENT FINDINGS: This review has critically examined the recent evidence on outcomes of day care provision for older people with long-term conditions and will focus on three areas - physical functioning, intergenerational provision and measurement of outcomes. In terms of interventions to improve physical functioning for older people with long-term conditions attending day care, there are few studies and it is difficult to generalize but there appears to be a trend for positive impact on physical functioning when activities are incorporated into a day care programme. There is a paucity of research on intergenerational provision, however, the small number of studies suggest positive benefits. Studies measuring outcomes for older people with long-term conditions attending day care services are very limited in terms of outcome data with the exception of a Canadian study, which suggested that attendance at day care could reduce hospital attendance and admissions. SUMMARY: This review reveals a lack of research of day care provision for older people with long-term conditions. There is a suggestion in the small number of articles included in this review that there can be benefits both in terms of global outcomes of attendance and in improved physical functioning; there is limited evidence of the value of intergenerational provision. Robust research with collection of meaningful outcomes is required to ensure that the increasing number of older people with long-term conditions are enabled to access high quality day care provision. PMID- 30300155 TI - Targeting IL-1alpha in cancer cachexia: a narrative review. AB - PURPOSE OF REVIEW: Cachexia is defined as ongoing loss of skeletal muscle mass, with or without depletion of adipose tissue and is a common syndrome in cancer patients, affecting 50% of those diagnosed. Cachexia, which cannot be fully reversed and causes significant functional impairment is caused by various mechanisms such as an altered energy balance and disruption of homeostatic control by the central nervous system. This central nervous system deregulation involves hypothalamic pituitary adrenal (HPA) axis stimulation, which can be triggered by IL-1R1 engagement on neuronal processes and endothelium in the microvasculature of the hypothalamus. This review will explore current evidence regarding both the importance of IL-1alpha in the various components of cancer cachexia and its potential as a therapeutic target. RECENT FINDINGS: IL-1alpha, which signals through IL-1R1, has been identified as a key agonist in the IL-1 pathway. As such, IL-1alpha has been explored as a therapeutic target in cancer cachexia, leading to the development of bermekimab, a mAb which neutralizes IL 1alpha. With a limited array of medication currently available to treat cancer cachexia, bermekimab represents a possible therapy. SUMMARY: IL-1alpha is a key mediator in cachexia development and targeting this may be a viable therapeutic target.

PMID- 30300157 TI - Early Resumption of beta Blockers Is Associated with Decreased Atrial Fibrillation after Noncardiothoracic and Nonvascular Surgery: A Cohort Analysis. AB - WHAT WE ALREADY KNOW ABOUT THIS TOPIC: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Beta (beta) blockers reduce the risk of postoperative atrial fibrillation and should be restarted after surgery, but it remains unclear when best to resume beta blockers postoperatively. The authors thus evaluated the relationship between timing of resumption of beta blockers and atrial fibrillation in patients recovering from noncardiothoracic and nonvascular surgery. METHODS: The authors evaluated 8,201 adult beta-blocker users with no previous history of atrial fibrillation who stayed at least two nights after noncardiothoracic and nonvascular surgery as a retrospective observational cohort. After propensity score matching on baseline and intraoperative variables, 1,924 patients who did resume beta blockers by the end of postoperative day 1 were compared with 973 patients who had not resumed by that time on postoperative atrial fibrillation using logistic regression. A secondary matched analysis compared 3,198 patients who resumed beta blockers on the day of surgery with 3,198 who resumed thereafter. RESULTS: Of propensity score-matched patients who resumed beta blockers by end of postoperative day 1, 4.9% (94 of 1,924) developed atrial fibrillation, compared with 7.0% (68 of 973) of those who resumed thereafter (adjusted odds ratio, 0.69; 95% CI, 0.50-0.95; P = 0.026). Patients who resumed beta blockers on day of surgery had an atrial fibrillation incidence of 4.9% versus 5.8% for those who started thereafter (odds ratio, 0.84; 95% CI, 0.67-1.04; P = 0.104). CONCLUSIONS: Resuming beta blockers in chronic users by the end of the first postoperative day may be associated with lower odds of in hospital atrial fibrillation. However, there seems to be little advantage to restarting on the day of surgery itself. PMID- 30300158 TI - Achieved Gain and Subjective Outcomes for a Wide-Bandwidth Contact Hearing Aid Fitted Using CAM2. AB - OBJECTIVES: The objective of this study was to test the ability to achieve, maintain, and subjectively benefit from extended high-frequency amplification in a real-world use scenario, with a device that restores audibility for frequencies up to 10 kHz. DESIGN: A total of 78 participants (149 ears) with mild to moderately-severe sensorineural hearing loss completed one of two studies conducted across eight clinical sites. Participants were fitted with a light driven contact hearing aid (the Earlens system) that directly drives the tympanic membrane, allowing extended high-frequency output and amplification with minimal acoustic feedback. Cambridge Method for Loudness Equalization 2 - High Frequency (CAM2)-prescribed gains for experienced users were used for initial fitting, and adjustments were made when required according to participant preferences for loudness and comfort or when measures of functional gain (FG) indicated that more or less gain was needed. Participants wore the devices for an extended period. Prescribed versus adjusted output and gain, frequency-specific FG, and self perceived benefit assessed with the Abbreviated Profile of Hearing Aid Benefit, and a custom questionnaire were documented. Self-perceived benefit results were compared with those for unaided listening and to ratings with participants' own acoustic hearing aids. RESULTS: The prescribed low-level insertion gain from 6 to 10 kHz averaged 53 dB across all ears, with a range from 26 to 86 dB. After adjustment, the gain from 6 to 10 kHz decreased to an average of 45 dB with a range from 16 to 86 dB. Measured FG averaged 39 dB from 6 to 10 kHz with a range from 11 to 62 dB. Abbreviated Profile of Hearing Aid Benefit results revealed a significant improvement in communication relative to unaided listening, averaging 28 to 32 percentage points for the background noise, reverberation, and ease of communication subscales. Relative to participants' own hearing aids, the subscales ease of communication and aversiveness showed small but significant improvements for Earlens ranging from 6 to 7 percentage points. For the custom satisfaction questionnaire, most participants rated the Earlens system as better than their own hearing aids in most situations. CONCLUSIONS: Participants used and reported subjective benefit from the Earlens system. Most participants preferred slightly less gain at 6 to 10 kHz than prescribed for experienced users by CAM2, preferring similar gains to those prescribed for inexperienced users, but gains over the extended high frequencies were high relative to those that are currently available with acoustic hearing aids.This is an open access article distributed under the Creative Commons Attribution License 4.0 (CCBY), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. PMID- 30300159 TI - Mesenchymal stromal cells in kidney transplantation. AB - PURPOSE OF REVIEW: Mesenchymal stromal cells (MSC) have emerged as one of the most promising candidates for immunomodulatory cell therapy in kidney transplantation. Here we describe novel insights into the MSC mechanism of action and provide an overview of initial safety and feasibility studies with MSC in kidney transplantation. RECENT FINDINGS: Clinical studies of MSC-based cell therapy in kidney transplant recipients demonstrated the safety and feasibility of cell therapy and provide the first encouraging evidence of the efficacy of MSC in enabling the minimization of immunosuppressive drugs. In our initial experience with MSC-based therapy in kidney transplant recipients we carried out extensive clinical and immunological monitoring of MSC-treated patients and found possible biomarkers of MSC immunomodulation in some of them. Based on these biomarkers we identified a patient in whom complete discontinuation of immunosuppression has been achieved safely and successfully. SUMMARY: Many issues should be addressed before MSC-based therapy becomes a standard treatment protocol for kidney transplantation. A better understanding of the MSC mechanism of action and the identification of biomarkers of response to therapy will inform the rational design of the most effective clinical protocol and the selection of patients amenable to safe immunosuppressive drug withdrawal.

PMID- 30300160 TI - Prognosis of patients with gastric variceal bleeding after endoscopic variceal obturation according to the type of varices. AB - BACKGROUND AND AIMS: This study was performed to evaluate the treatment efficacy of endoscopic variceal obturation (EVO) in patients with gastric variceal bleeding (GVB) according to the type of varices. PATIENTS AND METHODS: All patients who were treated with EVO for bleeding from gastric varices (GVs) were included. Patients with a previous history of endoscopic treatment for GVB and those with accompanying portal vein invasion by hepatocellular carcinoma or other malignancy were excluded. RESULTS: Ninety-one patients with GVB were included. Mean age was 59.4+/-12.4 years and 72 (79.1%) patients were men. The types of varices were gastroesophageal varices (GOV) type 1 (GOV1), GOV2, and isolated gastric varices type 1 (IGV1) in 30 (33.3%), 35 (38.5%), and 26 (28.6%) patients, respectively. Hemostasis and GV obliteration were achieved in 88 (96.7%) and 81 (89.0%) patients, respectively. Among 81 patients with GV obliteration, GV recurred in 26 (32.1%) patients. The GV recurrence rate was significantly lower in patients with GOV1 than in those with GOV2 (P=0.007), while it was comparable between patients with GOV1 and IGV1 (P=0.111) and between patients with GOV2 and IGV1 (P=0.278). Variceal rebleeding occurred in 11 (13.6%) patients. GVB recurrence rate was significantly higher in patients with GOV2 than in those with GOV1 (P=0.034) and IGV1 (P=0.018), while it was comparable between patients with GOV1 and IGV1 (P=0.623). Mortality rate was comparable among the three groups. CONCLUSIONS: EVO was very effective in patients with GVB. GV recurrence and GV rebleeding were significantly lower in patients with GOV1 than in those with GOV2. PMID- 30300162 TI - 2018 Frank Stinchfield Award: Spinopelvic Hypermobility Is Associated With an Inferior Outcome After THA: Examining the Effect of Spinal Arthrodesis. AB - BACKGROUND: Many patients undergo both THA and spinal arthrodesis, and those patients may not fare as well as those who undergo one procedure but not the other. The mechanisms of how spinal arthrodesis affects patient function after THA remain unclear. QUESTIONS/PURPOSES: The aims of our study were to (1) determine how patient-reported outcome measures (PROMs), including the Oxford hip score as well as dislocations and complications compare after THA between patients with and without spinal arthrodesis; (2) characterize sagittal pelvic changes in these patients that occur when moving between different functional positions and test for differences between patients with and without spinal arthrodesis; and (3) assess whether differences in sagittal pelvic dynamics are associated with PROMs, complications, and dislocations after THA. METHODS: In this case-control study, we identified 42 patients (60 hips) who had undergone both THA and spinal arthrodesis between 2002 and 2016 and who were available for followup at a minimum of 12 months (mean, 6 +/- 5 years) after the later of the two procedures. These cases were case-control-matched for age, gender, and body mass index with 42 patients (60 hips) who underwent only THA and had no known spinal pathology. All patients completed PROMs, including the Oxford hip score, and underwent four radiographs of the pelvis and spinopelvic complex in three positions (supine, standing, and deep-seated). Cup orientation and various spinopelvic parameters, including pelvic tilt and pelvic-femoral angle, were measured. The difference in pelvic tilt between standing and seated allowed for patient classification based on spinopelvic mobility into normal (+/- 10 degrees 30 degrees ), stiff (< +/- 10 degrees ) or hypermobile (> +/- 30 degrees ) groups. RESULTS: Compared with the THA-only group, the THA-spinal arthrodesis group had inferior PROMs (Oxford hip score, 33 +/- 10 versus 43 +/- 6; p < 0.001) and more surgery-related complications (such as dislocation, loosening, periprosthetic fracture or infection, psoas irritation) (12 versus 3; p = 0.013), especially dislocation (5 versus 0; p = 0.023). We detected no difference in change of pelvic tilt between supine and standing positions between the groups. When standing, patients undergoing THA-spinal arthrodesis had greater pelvic tilt (25 degrees +/- 11 degrees versus 17 degrees +/- 8 degrees ; p < 0.001) and the hip was more extended (193 degrees +/- 22 degrees versus 185 degrees +/- 30 degrees ; p = 0.012). We found that patients undergoing THA-spinal arthrodesis were more likely to have spinopelvic hypermobility (12 of 42 versus three of 42; odds ratio, 5.2; p = 0.02) with anterior tilting of the pelvis. Of all biomechanical parameters, only spinopelvic hypermobility was associated with inferior PROMs (Oxford hip score, 35 +/- 9 versus 40 +/- 7 in normal mobility; p = 0.049) and was also present in dislocating hips that underwent revision despite acceptable cup orientation. CONCLUSIONS: In patients with spinal arthrodesis who have undergone THA, spinopelvic hypermobility is associated with inferior outcomes, including hip instability. Spinopelvic hypermobility should be routinely assessed because these patients may have a narrow zone of optimum cup orientation that would require new technology to define and assist the surgeon in obtaining it.Level of Evidence Level III, therapeutic study. PMID- 30300163 TI - Postmortem Diagnosis of Myocardial Infarction Due to Butane Gas Intoxication in a Child: A Case Report. AB - Volatile substance addiction and toxic gas inhalation are now an important health problem. The pleasure-based inhalation of butane gas, also known as lighter refill gas, is especially prevalent among children and young people. The most important reasons for this situation are that they are cheap and easy to obtain and lack of legal supervision. The exhaled gas is absorbed through the alveolar surface and rapidly enters the bloodstream and leads to clinical signs. It can cause dizziness, nausea, vomiting, confusion, hallucinations, and euphoria in the acute phase. In severe cases, bronchospasm, hypoxia, ventricular arrhythmia, cardiopulmonary arrest, and death can occur. Our case is one of the rare cases in the literature that was diagnosed by postmortem histopathological examination. Our case is a 15-year-old girl who was found in front of a tobacco product store. On gross examination, there was a hemorrhagic area under the aortic valve that continued to interventricular septum. There was no coronary artery lesion. Histopathological examination revealed hypereosinophilia and contraction band necrosis in myocardial fibers, which was more intense in papillary muscle. Immunohistochemical studies also supported early myocardial ischemic changes. Upon toxicological examination, butane gas was detected in lung and blood samples. PMID- 30300164 TI - Linearity, Bias, Intrascanner Repeatability, and Interscanner Reproducibility of Quantitative Multidynamic Multiecho Sequence for Rapid Simultaneous Relaxometry at 3 T: A Validation Study With a Standardized Phantom and Healthy Controls. AB - OBJECTIVES: The aim of this study was to evaluate the linearity, bias, intrascanner repeatability, and interscanner reproducibility of quantitative values derived from a multidynamic multiecho (MDME) sequence for rapid simultaneous relaxometry. MATERIALS AND METHODS: The NIST/ISMRM (National Institute of Standards and Technology/International Society for Magnetic Resonance in Medicine) phantom, containing spheres with standardized T1 and T2 relaxation times and proton density (PD), and 10 healthy volunteers, were scanned 10 times on different days and 2 times during the same session, using the MDME sequence, on three 3 T scanners from different vendors. For healthy volunteers, brain volumetry and myelin estimation were performed based on the measured T1, T2, and PD. The measured phantom values were compared with reference values; volunteer values were compared with their averages across 3 scanners. RESULTS: The linearity of both phantom and volunteer measurements in T1, T2, and PD values was very strong (R = 0.973-1.000, 0.979-1.000, and 0.982-0.999, respectively) The highest intrascanner coefficients of variation (CVs) for T1, T2, and PD were 2.07%, 7.60%, and 12.86% for phantom data, and 1.33%, 0.89%, and 0.77% for volunteer data, respectively. The highest interscanner CVs of T1, T2, and PD were 10.86%, 15.27%, and 9.95% for phantom data, and 3.15%, 5.76%, and 3.21% for volunteer data, respectively. Variation of T1 and T2 tended to be larger at higher values outside the range of those typically observed in brain tissue. The highest intrascanner and interscanner CVs for brain tissue volumetry were 2.50% and 5.74%, respectively, for cerebrospinal fluid. CONCLUSIONS: Quantitative values derived from the MDME sequence are overall robust for brain relaxometry and volumetry on 3 T scanners from different vendors. Caution is warranted when applying MDME sequence on anatomies with relaxometry values outside the range of those typically observed in brain tissue. PMID- 30300165 TI - Markers of mineralocorticoid receptor function: changes over time and relationship to response in patients with major depression. AB - The renin-angiotensin-aldosterone system and its hormone receptors, i.e. the angiotensin and mineralocorticoid receptor (MR), have emerged as important targets for central nervous system disorders and in particular for major depression. We have recently characterized baseline MR function as a predictor for treatment outcome with standard antidepressants. The aims of this study are (i) to characterize how strongly an early biomarker change (after 2 weeks) is related to outcome and (ii) whether these biomarker changes are related to the final outcome, that is, could serve as surrogate markers for response. Twenty four of 30 patients with unipolar major depression completed the observational trial. MR-related biomarkers were assessed at baseline, 2 weeks, and 6 weeks of standard antidepressant treatment. These biomarkers included slow wave sleep (SWS), salivary cortisol and aldosterone after awakening, heart rate variability measured as respiratory sinus arrhythmia (RSA), systolic blood pressure, salt taste intensity (STI), salt pleasantness (SP), and plasma electrolytes. The Hamilton depression rating scale with 21 items was primarily used to determine depression severity. In the overall sample, STI increased and SP decreased significantly with treatment without a clear relationship with treatment outcome. No other significant changes were observed. Reductions in cortisol and aldosterone after 2 weeks of treatment were significantly related to improvement after 6 weeks (P<0.05). SWS increase after 2 and 6 weeks was by trend (P<0.08) correlated to clinical improvement after 6 weeks. Systolic blood pressure differentiated responders and nonresponders at baseline (P<0.05), but did not change significantly during treatment. We earlier identified a relationship between clinical outcome and baseline values of STI, SP, and RSA only in male patients; therefore, changes in this subgroup were analyzed separately: in male treatment responders, a trend toward an increase in SWS occurred after 2 (P<0.07) and 6 (P<0.07) weeks. Further, a trend toward RSA reduction (P<0.07) was observed. Changes in STI and SP were similar to the total group, but did not reach levels of significance. Early changes in central MR-related biomarkers appear to influence the outcome of standard antidepressant treatment: reduced salivary cortisol, increased SWS, and reduced RSA are linked to a better treatment outcome. These features point to a mechanism involving increased central MR activation in responders to standard antidepressants, but not in nonresponders. PMID- 30300166 TI - Anaesthesia care team improves outcomes in surgical patients compared with solo anaesthesiologist: An observational study. AB - BACKGROUND: In anaesthesiology, little attention has been drawn to the role of anaesthesia nurses as support personnel on quality of care. OBJECTIVES: To compare an anaesthesiologist alone (solo anaesthesiologist) with an anaesthesia care team (anaesthesiologist and anaesthesia nurse). DESIGN: An observational study. SETTING: A single centre study. PARTICIPANTS: Anaesthesiologists and anaesthesia nurses. INTERVENTION: Anaesthesia performed by solo anaesthesiologists compared with anaesthesia care teams. MAIN OUTCOME MEASURES: 30-day postoperative mortality and hospital length of stay. Propensity score matching was performed by logistic regression to adjust for baseline differences between the two groups and pairs of perfectly matched patients were formed. RESULTS: Anaesthesia was performed by solo anaesthesiologists in 2832 patients and by an anaesthesia care team in 2842 patients. Matching with 2095 pairs of perfectly matched patients was formed. The two groups were comparable in respect of sex and duration of anaesthesia but differed notably for age, American Society of Anesthesiologists' physical status score and type of surgery. Logistic regression showed a significantly lower 30-day mortality rate for the anaesthesia care teams compared with solo anaesthesiologists (0.76 vs. 1.56%, P = 0.0014). Length of hospital stay was also significantly reduced when an anaesthesia nurse was present (4.9 +/- 10.1 vs. 5.6 +/- 11.5 days, P = 0.0011). CONCLUSION: Anaesthesia given by teams of anaesthesiologists and anaesthesia nurses is associated with decreased 30-day postoperative mortality and shorter length of stay when compared with solo anaesthesiologists. Even without any demonstration of causality, this emphasises the benefits of the anaesthesia care team model. TRIAL REGISTRATION: CCB 325201730849. PMID- 30300167 TI - Phonemic fluency improved after inhibitory transcranial magnetic stimulation in a case of chronic aphasia. AB - Twenty-six months after a left hemispheric ischemic stroke an aphasic patient showed a significant improvement in verbal fluency following ten daily sessions of inhibitory 1 Hz repetitive transcranial magnetic stimulation over the right cortex homologous to the Broca's area.No improvement was observed for other linguistic functions or for executive ones. Results confirm the segregation of neural circuitries subtending phonemic and semantic fluency and suggest a selective usefulness of the repetitive transcranial magnetic stimulation treatment.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30300168 TI - Factors Affecting Racial Disparities in End-of-Life Care Costs Among Lung Cancer Patients: A SEER-Medicare-based Study. AB - OBJECTIVES: Racial disparities exist in end-of-life lung cancer care, which could potentially lead to considerable racial differences in end-of-life care costs. This study for the first time estimates the racial differences in end-of-life care costs among lung cancer patients, and identifies and quantifies factors that contribute the most to these differences using a statistical decomposition method. METHODS: This is a retrospective analysis of patients 66 years and older, diagnosed with stage I-IV lung cancer, who died on or before December 31, 2013, using the Surveillance Epidemiology and End Result-Medicare data from 1991 to 2013. Ordinary least square regression of logarithmically transformed cost was used to estimate racial differences in end-of-life care costs among lung cancer patients. Blinder-Oaxaca decomposition was used to identify and quantify factors that contributed the most to these differences. RESULTS: Non-Hispanic blacks had 10% to 13% higher end-of-life care costs as compared with non-Hispanic whites. Geographic variations, baseline comorbidity indices and stage at diagnosis contributed the most to explaining the racial differences in costs, with geographic variation explaining most of the differences. However, the observed factors could only explain 25% to 32% of the racial differences in end-of-life care costs. CONCLUSIONS: Geographic differences in access to timely and appropriate care, and provider practice patterns, should be examined to understand the reasons behind geographic variations in racial disparity. Provider level educational interventions to reduce small area practice variations and differential management of patients by race, as well as racially sensitive patient-level educational and navigational interventions might be critical in improving quality of care and reducing costs during end-of-life. PMID- 30300169 TI - How to Optimize Cancer Treatment in Older Patients: An Overview of Available Geriatric Tools. AB - Cancer is a disease of older people, but this age group has often been excluded from clinical trials of cancer, which leads to poor transportability of standardized treatments in older cancer patients. One of the main reasons for the exclusion is the heterogeneity of older people in several domains: social environment, comorbidities, dependency, functional status, nutritional status, cognition status, and mood status. Comprehensive geriatric assessment aims to assess this heterogeneity and has identified frequent health problems often unknown before therapeutic decisions, which allows for targeted geriatric interventions with or without follow-up and appropriate cancer treatment selection. Several tools and scores have been developed for a complementary approach. These tools have the following characteristics: they screen for vulnerability to select patients who may benefit from a comprehensive geriatric assessment; are predictive tools for survival, postoperative complications, or chemotherapy-related toxicity; are decisional algorithms for cancer treatment; or define a core set of geriatric data to be collected in clinical cancer trials. Here, we present an overview of the geriatric tools that were published in PubMed from 2000 to 2017, that could help in the therapeutic decision-making for older cancer patients. PMID- 30300170 TI - Factors Associated With Head and Neck Cancer Hospitalization Cost and Length of Stay-A National Study. AB - OBJECTIVES: The aim of the study was to estimate hospitalization cost, and factors associated with hospitalization costs and length of stay (LOS) of patients treated for head and neck cancer in the United States. METHODS: Data on 71,440 weighted hospital admissions from the 2014 National Inpatient Sample with a diagnosis of head and neck cancer were examined. Multivariable linear regression models estimated factors associated with hospitalization costs, and negative binomial regression models were used to identify factors associated with hospital LOS. Factor variables included characteristics of the patient, clinical, and hospital characteristics. RESULTS: The average hospitalization cost was US $18,371 and the average LOS was 6.6 days. LOS was significantly associated with admissions involving bacterial infection, major operating procedures, chemo procedure, and radiation procedure as well as admissions at medium or small bed size hospitals, and rural hospitals. Admissions among black patients, elective admissions, admissions involving bacterial infection, major operating procedures, chemo procedure, radiation procedure, and advance comorbidities were associated with increased hospitalization costs. In contrast, admissions at urban nonteaching or rural had increased hospitalization costs. CONCLUSIONS: Admissions that involve higher number of comorbidities, metastasis, bacterial infection, radiation, and chemo procedures had longer hospital stay and higher cost whereas admissions are rural hospitals had shorter hospital stay and lower cost. Understanding these factors associated with increased LOS and hospitalization cost will help efforts to decrease health care cost and improve quality of care. PMID- 30300171 TI - Effect of Apneic Oxygenation on Tracheal Oxygen Levels, Tracheal Pressure, and Carbon Dioxide Accumulation: A Randomized, Controlled Trial of Buccal Oxygen Administration. AB - BACKGROUND: Apneic oxygenation via the oral route using a buccal device extends the safe apnea time in most but not all obese patients. Apneic oxygenation techniques are most effective when tracheal oxygen concentrations are maintained >90%. It remains unclear whether buccal oxygen administration consistently achieves this goal and whether significant risks of hypercarbia or barotrauma exist. METHODS: We conducted a randomized trial of buccal or sham oxygenation in healthy, nonobese patients (n = 20), using prolonged laryngoscopy to maintain apnea with a patent airway until arterial oxygen saturation (SpO2) dropped <95% or 750 seconds elapsed. Tracheal oxygen concentration, tracheal pressure, and transcutaneous carbon dioxide (CO2) were measured throughout. The primary outcome was maintenance of a tracheal oxygen concentration >90% during apnea. RESULTS: Buccal patients were more likely to achieve the primary outcome (P < .0001), had higher tracheal oxygen concentrations throughout apnea (mean difference, 65.9%; 95% confidence interval [CI], 62.6%-69.3%; P < .0001), and had a prolonged median (interquartile range) apnea time with SpO2 >94%; 750 seconds (750-750 seconds) vs 447 seconds (405-525 seconds); P < .001. One patient desaturated to SpO2 <95% despite 100% tracheal oxygen. Mean tracheal pressures were low in the buccal (0.21 cm.H2O; SD = 0.39) and sham (0.56 cm.H2O; SD = 1.25) arms; mean difference, -0.35 cm.H2O; 95% CI, 1.22-0.53; P = .41. CO2 accumulation during early apnea before any study end points were reached was linear and marginally faster in the buccal arm (3.16 vs 2.82 mm Hg/min; mean difference, 0.34; 95% CI, 0.30-0.38; P < .001). Prolonged apnea in the buccal arm revealed nonlinear CO2 accumulation that declined over time and averaged 2.22 mm Hg/min (95% CI, 2.21-2.23). CONCLUSIONS: Buccal oxygen administration reliably maintains high tracheal oxygen concentrations, but early arterial desaturation can still occur through mechanisms other than device failure. Whereas the risk of hypercarbia is similar to that observed with other approaches, the risk of barotrauma is negligible. Continuous measurement of advanced physiological parameters is feasible in an apneic oxygenation trial and can assist with device evaluation. PMID- 30300172 TI - Contemporary Academic Contributions From Anesthesiologists in Adult Critical Care Medicine. AB - BACKGROUND: Anesthesiology has a long relationship with critical care medicine (CCM). However, US anesthesiologists are less likely to practice CCM than non-US anesthesiologists. To date, no studies have compared academic contributions in CCM between US anesthesiologists and non-US anesthesiologists. The objective of our study was to use recent trends in critical care publications as a surrogate for academic contribution among US and non-US anesthesiologists. METHODS: Research articles published between 2010 and 2015 in 3 anesthesiology journals (Anesthesiology, Anesthesia & Analgesia, and British Journal of Anaesthesia) and 3 multidisciplinary CCM journals (Critical Care Medicine, Intensive Care Medicine, and Journal of Critical Care) were reviewed. Author information, including the primary department appointment and geographic location for the first and senior author(s), and article details, including topic and publication type, were collected. Odds ratios for having a first or senior author from the United States were calculated. Anesthesiologists' contributions in individual journals were summarized, as were trends in anesthesiology CCM publications during the 6-year study period. RESULTS: A total of 3831 articles were reviewed, with 1050 (27.4%) having US authors. Eighty-two and one-half percent of CCM articles in anesthesiology journals had a US anesthesiologist as first author, and 81% had a US anesthesiologist as senior author, while fewer CCM articles in multidisciplinary journals had a US anesthesiologist as first (12.1%) or senior (12.3%) author. When considering all publications, 16.3% and 16.4% of articles had a US anesthesiologist as the first or senior author compared with articles for which non-US anesthesiologists were first (23.8%) or senior (20.9%) authors. The odds of having a US anesthesiologist as first or senior author compared to a non-US anesthesiologist for all publications were 0.6 (0.5-0.7) and 0.7 (0.6 0.9). The number of publications trended downward for both US anesthesiologists and non-US anesthesiologists during the study period. CONCLUSIONS: When compared to non-US anesthesiologists, US anesthesiologists had more CCM publications in anesthesiology journals and fewer publications in multidisciplinary CCM journals. The number of anesthesiology CCM publications decreased for both US and non-US anesthesiologists throughout the study period. PMID- 30300173 TI - Mild Perioperative Hypothermia and Myocardial Injury: A Retrospective Cohort Analysis. AB - BACKGROUND: We tested the primary hypothesis that final intraoperative esophageal temperature is associated with increased odds of a composite of in-hospital all cause mortality and myocardial injury within 7 days after noncardiac surgery. Secondary exposures were time-weighted average intraoperative temperature and area <37 degrees C threshold. METHODS: Myocardial injury was defined by postoperative fourth-generation troponin T >=0.03 ng/mL apparently due to cardiac ischemia. Data were extracted for inpatients who had noncardiac surgery with general anesthesia at the Cleveland Clinic between 2012 and 2015. All had esophageal temperature monitoring and routine postoperative troponin monitoring. We estimated the confounder-adjusted association between final intraoperative esophageal temperature and the collapsed composite with multivariable logistic regression. We similarly estimated associations with time-weighted average intraoperative temperature and area <37 degrees C. RESULTS: Two thousand two hundred ten patients were included. Nearly all final esophageal temperatures were 36 degrees C-37 degrees C. Ninety-seven patients (4.4%) had myocardial injury, and 7 (0.3%) died before discharge. Final intraoperative core temperature was not associated with the collapsed composite: odds ratio, 0.91 (95% confidence interval, 0.68-1.24) per 1 degrees C decrease. Similarly, neither of the secondary exposures was associated with the composite outcome. CONCLUSIONS: We did not observe an association between mild perioperative hypothermia and mortality or myocardial injury in adults having noncardiac surgery. However, the range of final intraoperative temperatures was small and largely restricted to the normothermic range (36 degrees C-37 degrees C). Trials are needed to further assess the effect of temperature on myocardial injury. PMID- 30300174 TI - Intensive Care Unit Readmission After Left Ventricular Assist Device Implantation: Causes, Associated Factors, and Association With Patient Mortality. AB - BACKGROUND: Previous studies on readmissions after left ventricular assist device (LVAD) implantation have focused on hospital readmissions after dismissal from the index hospitalization. Because few data exist, the purpose of this study was to examine intensive care unit (ICU) readmissions in patients during their initial hospitalization for LVAD implantation to determine reasons for, factors associated with, and incidence of mortality after ICU readmission. METHODS: A retrospective analysis was performed from February 2007 to March 2015 of patients at our institution receiving first-time LVAD implantation. After LVAD implantation, patients dismissed from the ICU who then required ICU readmission before hospital dismissal were compared to those not requiring ICU readmission before hospital dismissal with respect to preoperative, intraoperative, and postoperative factors. RESULTS: Among 287 LVAD patients, 266 survived their initial ICU admission, of which 49 (18.4%) required ICU readmission. The most common reasons for readmission were bleeding and respiratory failure. Factors found to be univariably associated with ICU readmission were preoperative hemoglobin, preoperative aspartate aminotransferase, preoperative atrial fibrillation, preoperative dialysis, longer cardiopulmonary bypass times, and higher intraoperative allogeneic blood transfusion requirements. Multivariable analysis revealed ICU readmission to be independently associated with preoperative dialysis (odds ratio, 12.86; 95% confidence interval, 3.16-52.28; P < .001). Overall mortality at 1 year was 22.6%. Survival after hospital dismissal was worse for patients who required ICU readmission during the index hospitalization (adjusted hazard ratio, 2.35; 95% confidence interval, 1.15-4.81; P = .019). CONCLUSIONS: ICU readmission after LVAD implantation occurred relatively frequently and was significantly associated with 1-year mortality after hospital dismissal. These data can perhaps be used to identify subsets of LVAD patients at risk for ICU readmission and may lead to implementation of practice changes to mitigate ICU readmissions. Future larger and prospective studies are warranted. PMID- 30300175 TI - Recognizing the Chinese Pioneer of Neuraxial Labor Analgesia: Dr Guang-Bo Zhang and Her Unpublished Manuscript From More Than a Half-Century Ago. AB - Dr Guang-Bo Zhang was the first anesthesiologist to administer and study the effects of labor epidural analgesia in China. Between September 1963 and March 1964, she conducted an observational study evaluating the effects of neuraxial analgesia for laboring women. She presented her research and prepared an article; however, due to the Great Proletarian Cultural Revolution (Cultural Revolution), which began in 1966, her work went unpublished. She successfully preserved her unpublished article, notes, and slides throughout the Cultural Revolution by hiding them in a countryside location near Beijing. These 54-year-old, previously unpublished documents represent the first known clinical trial of neuraxial labor analgesia conducted in China. PMID- 30300176 TI - Emergency Department Airway Management Responsibilities in the United States. AB - BACKGROUND: In the 1990s, emergency medicine (EM) physicians were responsible for intubating about half of the patients requiring airway management in emergency rooms. Since then, no studies have characterized the airway management responsibilities in the emergency room. METHODS: A survey was sent via the Eastern Association for Surgery and Trauma and the Trauma Anesthesiology Society listservs, as well as by direct solicitation. Information was collected on trauma center level, geographical location, department responsible for intubation in the emergency room, department responsible for intubation in the trauma bay, whether these roles differed for pediatrics, whether an anesthesiologist was available "in-house" 24 hours a day, and whether there was a protocol for anesthesiologists to assist as backup during intubations. Responses were collected, reviewed, linked by city, and mapped using Python. RESULTS: The majority of the responses came from the Eastern Association for Surgery of Trauma (84.6%). Of the respondents, 72.6% were from level-1 trauma centers, and most were located in the eastern half of the United States. In the emergency room, EM physicians were primarily responsible for intubations at 81% of the surveyed institutions. In trauma bays, EM physicians were primarily responsible for 61.4% of intubations. There did not appear to be a geographical pattern for personnel responsible for managing the airway at the institutions surveyed. CONCLUSIONS: The majority of institutions have EM physicians managing their airways in both emergency rooms and trauma bays. This may support the observations of an increased percentage of airway management in the emergency room and trauma bay setting by EM physicians compared to 20 years ago. PMID- 30300177 TI - Fluid Challenge During Anesthesia: A Systematic Review and Meta-analysis. AB - BACKGROUND: Assessing the volemic status of patients undergoing surgery is part of the routine management for the anesthesiologist. This assessment is commonly performed by means of dynamic indexes based on the cardiopulmonary interaction during mechanical ventilation (if available) or by administering a fluid challenge (FC). The FC is used during surgery to optimize predefined hemodynamic targets, the so-called Goal-Directed Therapy (GDT), or to correct hemodynamic instability (non-GDT). METHODS: In this systematic review, we considered the FC components in studies adopting either GDT or non-GDT, to assess whether differences exist between the 2 approaches. In addition, we performed a meta analysis to ascertain the effectiveness of dynamic indexes pulse pressure variation (PPV) and stroke volume (SV) variation (SVV), in predicting fluid responsiveness. RESULTS: Thirty-five non-GDT and 33 GDT studies met inclusion criteria, including 5017 patients. In the vast majority of non-GDT and GDT studies, the FC consisted in the administration of colloids (85.7% and 90.9%, respectively). In 29 non-GDT studies, the colloid infused was the 6% hydroxyethyl starch (6% HES; 96.6% of this subgroup). In 20 GDT studies, the colloid infused was the 6% HES (66.7% of this subgroup), while in 5 studies was a gelatin (16.7% of this subgroup), in 3 studies an unspecified colloid (10.0% of this subgroup), and in 1 study albumin (3.3%) or, in another study, both HES 6% and gelatin (3.3%). In non-GDT studies, the median volume infused was 500 mL; the time of infusion and hemodynamic target to assess fluid responsiveness lacked standardization. In GDT studies, FC usually consisted in the administration of 250 mL of colloids (48.8%) in 10 minutes (45.4%) targeting an SV increase >10% (57.5%). Only in 60.6% of GDT studies, a safety limit was adopted. PPV pooled area under the curve (95% confidence interval [CI]) was 0.86 (0.80-0.92). The mean (standard deviation) PPV threshold predicting fluid responsiveness was 10.5% (3.2) (range, 8%-15%), while the pooled (95% CI) sensitivity and specificity were 0.80 (0.74-0.85) and 0.83 (0.73-0.91), respectively. SVV pooled area under the curve (95% CI) was 0.87 (0.81-0.93). The mean (standard deviation) SVV threshold predicting fluid responsiveness was 11.3% (3.1) (range, 7.5%-15.5%), while the pooled (95% CI) sensitivity and specificity were 0.82 (0.75-0.89) and 0.77 (0.71 0.82), respectively. CONCLUSIONS: The key components of FC including type of fluid (colloids, often 6% HES), volume (500 and 250 mL in non-GDT studies and GDT studies, respectively), and time of infusion (10 minutes) are quite standardized in operating room. However, pooled sensitivity and specificity of both PPV and SVV are limited. PMID- 30300179 TI - The Importance of Differentiating Charges and Cost. PMID- 30300178 TI - Regional Analgesia Added to General Anesthesia Compared With General Anesthesia Plus Systemic Analgesia for Cardiac Surgery in Children: A Systematic Review and Meta-analysis of Randomized Clinical Trials. AB - BACKGROUND: The aim of this systematic review was to compare the effects of regional analgesic (RA) techniques with systemic analgesia on postoperative pain, nausea and vomiting, resources utilization, reoperation, death, and complications of the analgesic techniques in children undergoing cardiac surgery. METHODS: A search was done in May 2018 in PubMed, Embase, and the Cochrane Central Register of Controlled Trials for randomized controlled trials comparing RA techniques with systemic analgesia. Risks of bias of included trials were judged with the Cochrane tool. Data were analyzed with fixed- (I < 25%) or random-effects models (I >= 25%). The quality of evidence was graded according to the Grading of Recommendations Assessment, Development, and Evaluation working group scale. RESULTS: We included 14 randomized controlled trials with 605 participants (312 to RA and 293 to the comparator). RA reduces pain up to 24 hours after surgery. At 6-8 hours after surgery, the standardized mean difference was -0.81 (95% confidence interval [CI], -1.22 to -0.40; low-quality evidence). We did not find a difference for nausea and vomiting (risk ratio [RR], 0.89; 95% CI, 0.61-1.31; very low-quality evidence), duration of tracheal intubation (standardized mean difference, -0.18; 95% CI, -0.40 to 0.05; low-quality evidence), intensive care unit length of stay (mean difference, -0.10 hours; 95% CI, -1.31 to 1.12 hours; low-quality evidence), hospital length of stay (mean difference, -0.02 days; 95% CI, -1.16 to 1.12 days; low-quality evidence), reoperation (RR, 0.76; 95% CI, 0.17-3.28; low-quality evidence), death (RR, 0.50; 95% CI, 0.05-4.94; low-quality evidence), and respiratory depression (RR, 2.06; 95% CI, 0.20-21.68; very low quality evidence). No trial reported signs of local anesthetic toxicity or lasting neurological or infectious complications related to the RA techniques. One trial reported 1 transient ipsilateral episode of diaphragmatic paralysis with intrapleural analgesia that resolved with cessation of local anesthetic administration. CONCLUSIONS: Compared to systemic analgesia, RA techniques reduce postoperative pain up to 24 hours in children undergoing cardiac surgery. Currently, there is no evidence that RA for pediatric cardiac surgery has any impact on major morbidity and mortality. These results should be interpreted cautiously because they represent a meta-analysis of small and heterogeneous studies. Further studies are needed.

PMID- 30300181 TI - Resting Hemodynamics and Response to Exercise Using the 6-Minute Walk Test in Late Pregnancy: An International Prospective Multicentre Study. AB - BACKGROUND: Cardiac disease is the leading cause of maternal death. Assessment of cardiovascular fitness is important in pregnant women because it is linked to increased risk of cardiac disease but is rarely undertaken or studied. The 6 Minute Walk Test (6MWT) is a safe exercise test but is not used in pregnancy. We determined the 95% reference interval for resting heart rate (HR) and distance walked for the 6MWT, as well as hemodynamic recovery variables, and quantified expectations and actual experiences of exertion and breathlessness with exercise in late pregnancy. METHODS: After institutional research board approval (Australian and New Zealand Clinical Trials Registry Number: 12615000964516), 300 healthy term nulliparous pregnant women performed the 6MWT at 3 tertiary referral obstetric hospitals using a standardized protocol. Each woman underwent two 6MWT with maximum 15-minute recovery period after each test. Hemodynamic variables were measured at rest and after exercise. Participants were asked 4 questions, 2 regarding expectation and 2 regarding actual experience, using the Rating of Perceived Exertion scale and Modified Borg Dyspnea scale. RESULTS: Participant characteristics and resting variables were mean (standard deviation [SD]); age, 31 years (4.2 years); body mass index, 27 kg/m (2.9 kg/m); gestational age, 37 weeks (1.3 weeks); HR, 85 bpm (10.8 bpm) with 95% reference interval 64-106 bpm; systolic blood pressure, 112 mm Hg (10.2 mm Hg); diastolic blood pressure, 72 mm Hg (8.6 mm Hg); oxygen saturation, 98% (0.9%); and respiratory rate, 18 breaths/min (5.7 breaths/min). The mean (SD) average distance walked was 488 m (94.9 m) with a speed of 3.0 mph (0.64 mph) with a 95% reference interval of 302 674 m. The mean (SD) HR increase with exercise was 12 bpm (11.0 bpm) with a median [quartile] recovery time of 5.0 minutes [1-8 minutes]. A lower resting HR was associated with increased distance walked (r = -0.207; 95% confidence interval, -0.313 to -0.096; P < .001). A greater HR change with exercise was associated with increased recovery time from exercise (r = 0.736; 95% confidence interval, 0.697-0.784; P < .001). Sixty-three percent and 83% of participants, respectively, expected to be more exerted and breathless than they actually were with exercise. CONCLUSIONS: The 6MWT is feasible and applicable in term pregnant women. The reference intervals for resting HR and distance walked in the 6MWT have been generated. HR increases by approximately 12 bpm with submaximal exercise, and half of the women recovered within 5 minutes of submaximal exercise. Women expected to be more exerted and breathless than they actually were with exercise. PMID- 30300182 TI - Implementing a Pediatric Perioperative Surgical Home Integrated Care Coordination Pathway for Laryngeal Cleft Repair. AB - BACKGROUND: The Pediatric Perioperative Surgical Home (PPSH) model is an integrative care model designed to provide better patient care and value by shifting focus from the patient encounter level to the overarching surgical episode of care. So far, no PPSH model has targeted a complex airway disorder. It was hypothesized that the development of a PPSH for laryngeal cleft repair would reduce the high rates of postoperative resource utilization observed in this population. METHODS: Institutional review board approval was obtained for the purpose of data collection and analysis. A multidisciplinary team of anesthesiologists, surgeons, nursing staff, information technology specialists, and finance administrators was gathered during the PPSH development phase. Standardized perioperative (preoperative, intraoperative, and postoperative) protocols were developed, with a focus on preoperative risk stratification. Patients presenting before surgery with >=1 predefined medical comorbidity were triaged to the intensive care unit (ICU) postoperatively, while patients without severe systemic disease were triaged to a lower-acuity floor for overnight observation. The success of the PPSH protocol was defined by quality outcome and value measurements. RESULTS: The PPSH initiative included 120 patients, and the pre-PPSH period included 115 patients who underwent laryngeal cleft repair before implementation of the new process. Patients in the pre-PPSH period were reviewed and classified as ICU candidates or lower acuity floor candidates had they presented in the post-PPSH period. Among the 79 patients in the pre-PPSH period who were identified as candidates for the lower-acuity floor transfer, 70 patients (89%) were transferred to the ICU (P < .001). Retrospective analysis concluded that 143 ICU bedded days could have been avoided in the pre-PPSH group by using PPSH risk stratification. Surgery duration (P = .034) and hospital length of stay (P = .015) were found to be slightly longer in the group of pre PPSH observation unit candidates. Rates of 30-day unplanned readmissions to the hospital were not associated with the new PPSH initiative (P = .093). No patients in either group experienced emergent postoperative intubation or other expected complications. Total hospital costs were not lower for PPSH observation unit patients as compared to pre-PPSH observation unit candidates (difference = 8%; 95% confidence interval, -7% to 23%). CONCLUSIONS: A well-defined preoperative screening protocol for patients undergoing laryngeal cleft repair can reduce postoperative ICU utilization without affecting patient safety. Further research is needed to see if these findings are applicable to other complex airway surgeries. PMID- 30300183 TI - In Response. PMID- 30300184 TI - ACCEPTANCE SPEECH GIVEN BY SHAHEEN A.

PMID- 30300193 TI - Antidoping Science: Important Lessons From the Medical Sciences. AB - The ineffectiveness of antidoping programs in elite sport, largely due to human and political factors, is leading to a new resolve and greater transparency of antidoping authorities and those stakeholders interested in drug-free sport. The perception by the public, athletes, and the World Anti-Doping Agency (WADA) of antidoping science and current drug testing programs in elite sport varies widely from "ineffective" to "robust and reliable." Here, we discuss why a careful and considered reevaluation of the underlying premise of antidoping science is needed to bring this unique application of predictive/diagnostic science more in line with other areas of medicine. We show how the validity of doping tests are neither "stand-alone figures" generated under ideal laboratory conditions, nor figures that can be used in isolation to support the efficacy of the current drug testing program. Given the consequences of a failed doping test for the athlete, the sport, and multiple stakeholders (e.g., the sponsors), there is a need for transparent decision making to ensure those affected are well informed. We identify in this perspective the minimal essential data on drug testing that should be reported by antidoping laboratories to draw meaningful conclusions about the effectiveness of specific drug testing methods to support antidoping. In the absence of information on the validity of a doping test, it is not possible to plan or conduct "intelligent testing." It is imperative that the prevalence of doping and the likelihood of false-positive doping tests be regularly updated and made available for the wider antidoping research community to explore new approaches that could improve the validity of antidoping tests. True confirmatory testing which requires the use of different analytical technology and ideally an independent sample taken from an athlete with a positive test to transcend the present-day analysis of the B-sample. Indirect biomarkers of doping derived from new "omics"-based approaches may significantly improve the testing strategy. Biomarker molecular signatures are flexible enough to develop "normal ranges" optimized for either test sensitivity or specificity to detect a plethora of doping substances and methods.

This review summarizes our current understanding of the condition and evaluates the different options for assessing dyskinesis. Current methods for assessing scapula dyskinesis involve clinical observations, three-dimensional kinematics and three-dimensional wing computer tomography. Clinical observation is the most pragmatic method for assessing dyskinesis yielding inter-rater agreement of 79% and sensitivity of 76%. Similar sensitivities have been recorded using three-dimensional kinematics. Three-dimensional wing computer tomography has yielded a near-perfect interclass correlation coefficient of 0.972 when used to assess dyskinesis. Three-dimensional wing computer tomography, given its expense, low availability, and levels of irradiation, should be reserved for high performance athletes where detailed assessments need to be made to aid rehabilitation. Observational assessments should remain the main modality used for general assessment. PMID- 30300197 TI - Don't Just Blame it on the Veins: An Update on Vascular Exertional Limb Pain. AB - Exertional limb pain is a common problem encountered in recreational and competitive athletes. Affecting both the upper and lower extremities, this broad entity can be musculoskeletal, vascular, neurologic, oncologic, or infectious in origin. This article focuses on the vascular causes of exercise-related extremity pain, which encompass a cadre of elusive diagnoses. Specifically, we examine arterial endofibrosis, popliteal artery entrapment syndrome, and chronic exertional compartment syndrome of both the upper and lower extremities. For each of these conditions, we offer updates regarding the respective epidemiology, common signs and symptoms, worthwhile diagnostic modalities, and pertinent treatment options, all based on evidence and reports published over the past year. PMID- 30300198 TI - Occult Giant Cell Arteritis Concurrent With Pancreatic Carcinoma Revealed by 18F FDG PET/CT. AB - An F-FDG PET/CT was performed on a 74-year-old woman with pancreatic carcinoma and liver metastases. Occult giant cell arteritis, involving the aorta, truncus brachiocephalicus, subclavian arteries, axillaries, external carotid arteries, vertebral arteries, and superficial temporal arteries, was accidentally revealed. PMID- 30300199 TI - Splenosis of the Liver Capsule. AB - Splenosis, a form of ectopic splenic tissue, is generally caused by heterotopic autotransplantation of splenic tissues after traumatic splenic rupture or splenectomy. The implants are often localized intraperitoneally, mostly in the left upper quadrant and splenic region. Hepatic foci are seen only on rare occasions. The differential diagnosis of splenosis foci from malignant masses can be challenging by conventional imaging and lead to unnecessary invasive procedures. This manuscript presents radiological and scintigraphic images of splenosis foci located in the peritoneal cavity and liver capsule of a 46-year old man who underwent splenectomy due to traumatic splenic rupture 30 years ago. PMID- 30300200 TI - Prognostic Value of Volumetric Parameters of Pretreatment 18F-FDG PET/CT in Esophageal Cancer: A Systematic Review and Meta-analysis. AB - PURPOSE: We performed a systematic review and meta-analysis on the prognostic value of metabolic tumor volume (MTV) and total lesion glycolysis (TLG) derived from pretreatment F-FDG PET/CT in patients with esophageal cancer. METHODS: PubMed and EMBASE databases were searched until April 12, 2018, for studies that evaluated MTV or TLG as prognostic factors in esophageal cancer, with overall survival (OS) and event-free survival serving as the end points. Hazard ratios (HRs) were meta-analytically pooled using a random-effects model. Subgroup analyses based on the clinicopathological and PET variables were performed. RESULTS: In total, 16 studies with 1294 patients were included. The pooled HRs of MTV and TLG for OS were 2.26 (95% confidence interval [CI], 1.73-2.96) and 2.23 (95% CI, 1.73-2.87), respectively. Regarding event-free survival, the pooled HRs of MTV and TLG were 2.03 (95% CI, 1.66-2.49) and 2.57 (95% CI, 1.82-3.62), respectively. Metabolic tumor volume was found to be a significant prognostic factor for OS consistently across multiple subgroups classified based on stage, histological subtype, treatment, delineation of volume of interest, and the determination method of cutoff value, with pooled HRs ranging from 1.96 to 2.54. CONCLUSIONS: In patients with esophageal cancer, MTV and TLG derived from pretreatment F-FDG PET are significant prognostic factors. As prognostic biomarkers, volumetric metabolic parameters may bolster the role of F-FDG PET in the management of esophageal cancer. PMID- 30300201 TI - Endometrioid Intraepithelial Neoplasia: An Endometrial Precancer Detected by 18F FDG PET/CT. AB - The report describes a 55-year-old woman with postmenopausal abnormal vaginal spotting. PET/CT revealed focal hot F-FDG uptake in the fundus portion of the uterine cavity, and pathology of hysteroscopic dilation and curettage showed endometrioid intraepithelial neoplasia of uterine endometrium, an endometrial precancer. This case points to the significance of F-FDG PET/CT in determining the dilation and curettage site for the postmenopausal women with abnormal vaginal spotting. Increased F-FDG activity in the region of the uterus must be investigated to determine the possibilities of primary malignancies, metastases, and benign diseases. PMID- 30300202 TI - 18F-Choline and 18F-FDG PET/CT in a Patient With Diffuse Large B-Cell Lymphoma and Recurrent Prostate Cancer. AB - We report herein the case of an 80-year-old man who was referred for a biochemical recurrence of a high-risk prostate cancer. In addition to prostate cancer recurrence, F-choline allowed partial initial staging of an incidental diffuse large B-cell lymphoma which was further confirmed and staged using F-FDG and a biopsy. Two types of metabolic behavior were therefore identified using F choline and F-FDG which corresponded to 2 different uptake patterns, that is, those of the prostate and lymphoma tumoral cell contingents. PMID- 30300203 TI - 18F-DCFPyL PET/CT in Oncocytoma. AB - A 76-year-old man with biochemical failure after primary radiotherapy for prostate cancer had no malignant disease detected on Tc-MDP bone scan and diagnostic CT. Prostate-specific membrane antigen (PSMA), a type II transmembrane glycoprotein, is overexpressed in prostate cancer cells. The PSMA-targeted F DCFPyL PET/CT demonstrated lymph node disease and photopenic defects in the left kidney associated with a cyst and biopsy-proven oncocytoma. Prostate-specific membrane antigen is expressed in the neovasculature of several solid tumors. It has been reported that PSMA expression is seen in approximately 50% of oncocytoma versus 76% of clear cell renal carcinomas. Biopsy confirmation is needed regardless of F-DCFPyL avidity. PMID- 30300204 TI - FDG PET/CT in a Case of Dural Amyloidoma. AB - Dural amyloidoma is an unusual presentation of central nervous system amyloidosis. A 49-year-old woman presented with 1-month history of repeated episodes of vertigo. Precontrast MRI showed dural thickening over right frontal convexity with signal intensity similar to white matter. Postcontrast T1-weighted images showed remarkable enhancement of the lesion. Dural amyloidoma was confirmed by partial resection of the lesion. The patient underwent no further treatment. A follow-up FDG PET/CT showed increased FDG uptake of the residual dural amyloidoma. This case indicates dural amyloidoma should be included in the differential diagnosis of abnormal FDG uptake in dural lesions. PMID- 30300205 TI - Quality and Safety in Healthcare, Part XLVII: Resilience and Burnout. AB - The ability to come back from challenges such as the many factors predisposing to burnout is resilience. Individual strategies to prevent and recover from burnout can be learned and practiced. This includes mindfulness, meditation, yoga, various stress reduction techniques, coaching, counseling, mentoring, discussions in small groups, workshops, and better work life balance. Other approaches include building a support network, taking care of one's personal health, pursuing narrative medicine, engaging in reflection, emphasizing positive psychology approaches including learned optimism, encouraging a growth mindset, and volunteering. This article will focus on the topic of resilience as it is related to burnout, and subsequent articles will discuss some of the strategies for prevention and recovery in detail. PMID- 30300206 TI - Unexpected Bone Metastases in 99mTc-Pertechnetate Scan of Recurrent Goiter. AB - A 68-year-old woman who underwent a thyroidectomy for bilateral goiter 20 years ago was referred to our department. The examination revealed a newly occurred thyroid nodule in the right central lobe. Unexpectedly the Tc-pertechnetate scan revealed several extrathyroidal foci right-sided supraclavicular, beside a cold thyroid nodule in the right lower lobe. Consecutive surgery and histology confirmed the suspected diagnosis of follicular thyroid cancer with multiple bone metastases. Whole-body scintigraphy performed after the following radioiodine therapy indicated disseminated osseous metastases. PMID- 30300207 TI - Hypermetabolism Caused by Seizure Mimicking Tumor Recurrence. AB - A 41-year-old man had a right frontal grade I glioma resection 17 years ago. He was tumor free since. However, 1 month ago, he presented with an uncontrollable seizure, which raised the possibility of recurrent tumor. The FDG PET/CT brain scan showed increased tracer uptake at the margin of the previous resected tumor, suggesting the possibility of tumor recurrence. However, on a repeat FDG PET brain scan confirmed by electroencephalography monitory as an interictal study, no elevated FDG uptake was revealed at this site. These results indicate that the elevated F-FDG activity on the original study was a result of seizure. PMID- 30300208 TI - Update on sinus disease in children with cystic fibrosis: advances in treatment modalities, microbiology, and health-related quality-of-life instruments. AB - PURPOSE OF REVIEW: There is a lack of consensus with regards to the diagnosis and treatment of sinus disease in children with cystic fibrosis. Here, we review literature from the past 18 months in order to highlight the way forward in this contentious field. RECENT FINDINGS: Most of the literature (from the past 18 months) on sinus disease in pediatric cystic fibrosis focused on treatment approaches, bacteriology and immunology, and health-related quality-of-life (HRQOL) instruments. Quality studies have demonstrated that functional endoscopic sinus surgery (FESS) is as safe in children with or without cystic fibrosis; that the microbiology of the paranasal sinus in children with cystic fibrosis is different than that of their lungs; and, that HRQOL instruments may prove useful in determining sinonasal disease severity in children with cystic fibrosis. SUMMARY: Medical and surgical approaches appear to be viable in the treatment of sinonasal disease in pediatric cystic fibrosis; the microbiology and immunology of pediatric cystic fibrosis is proving more complex and nuanced than initially believed; and, HRQOL instruments show promise in reconciling differences between observable and clinically relevant sinus disease in pediatric cystic fibrosis patients. PMID- 30300209 TI - Velopharyngeal incompetence: role in paediatric swallowing deficits. AB - PURPOSE OF REVIEW: The purpose of this manuscript is to highlight the latest advances in diagnosis and management of velopharyngeal incompetence (VPI) as it pertains to swallowing deficits in children. This is timely and relevant as otolaryngologists are often amongst the first to diagnose and treat VPI. Although nasal regurgitation of a bolus is frequently transient, persistent problems can be associated with other swallowing problems and other significant medical problems. Furthermore, velopharyngeal incompetence has implications for speech production. RECENT FINDINGS: Persistent VPI associated with a swallowing deficit can be an isolated anomaly with or without a cleft palate or submucous cleft palate. VPI may be secondary to a cranial neuropathy, esophageal abnormality or associated with another airway anomaly, any of which may further contribute to dysphagia. Findings of additional anomalies may be suggestive of a syndrome. Workup should explore these potential causes. When velopharyngeal incompetence is associated with dysphagia, fiberoptic endoscopic evaluation of swallow (FEES) and videofluoroscopic swallow study (VFSS) can be helpful in diagnosis and management. The advantages and disadvantages of FEES and VFSS have been well delineated over the past few years. Similarly, nasopharyngoscopy and fluoroscopy are increasingly used in diagnosis and management of VPI that is associated with hypernasal resonance disorders. SUMMARY: Concurrent medical diagnoses or syndrome manifestations are often associated with or contribute significantly to the cause of dysphagia in children with VPI. As VPI can be a sign of brainstem vagal neuropathy, the clinician should investigate by imaging the CNS if other correlative symptoms of dysphagia and examination findings are present. Endoscopy is advocated for evaluation of vocal fold function. Fluoroscopy is best for further assessment of airway protection or safety of swallow. And, whenever indicated, additional workup is recommended to determine an underlying cause of the swallowing disorder. PMID- 30300210 TI - Recurrent respiratory papillomatosis: update 2018. AB - PURPOSE OF REVIEW: Recurrent respiratory papillomatosis (RRP) is the most common as well as the costliest benign airway neoplasm in the United States [Ivancic et al. (2018). Laryngoscope Investig Otolaryngol 3:22; Derkay (1995). Arch Otolaryngol Head Neck Surg 121:1386]. In addition, it is potentially deadly, with risk of airway obstruction as well as a 3-7% risk of malignant conversion [Schraff et al. (2004). Arch Otolaryngol Head Neck Surg 130:1039]. This review highlights exciting advancements over the past 1-2 years in scientific understanding of the pathophysiology, epidemiology, natural history, prevention, and treatment of this difficult disease. RECENT FINDINGS: Recent studies have yielded the following findings: The primary quality of life reduction that patients perceive is voice-related; the membranous vocal folds are the most frequently involved anatomic subsite in adult-onset RRP; there may be a correlation between laryngopharyngeal reflux, herpes simplex virus type 2, and adult-onset RRP; there has been a decline in RRP incidence in Australia following the implementation of a national vaccination program; addition of educational audiovisual aids assists in vaccine acceptance rates; preventive vaccination can be used as treatment for pediatric as well as adult RRP patients with demonstrable effects on antibody titers and reoperation rates; calreticulin linked DNA vaccines show promise in reducing the growth rate of human papilloma virus (HPV)11 E6/E7-expressing tumors in mice; injection of bevacizumab is associated with no adverse tissue affects; systemic bevacizumab is effective as a treatment for severe uncontrolled disease; pegylated interferon treatment is effective in select severe pediatric RRP disease; and finally, increased rates of programed death 1 T-lymphocyte infiltration and programed death-ligand 1 expression are seen on both papilloma and infiltrating immune cells. SUMMARY: RRP is declining in incidence but remains a challenging disease to treat with great costs to patients, families, and the healthcare system. As the disease continues to be better understood, new frontiers are opening in treatment, particularly for severe or poorly controlled disease. Until the disease can be eradicated, it remains a vital area of research to help prevent new cases and treat afflicted patients. PMID- 30300211 TI - Vocal fold nodules in children. AB - PURPOSE OF REVIEW: Vocal nodules are a common presentation in children, representing the most common cause of dysphonia. RECENT FINDINGS: Children with siblings, ADHD, and of male sex are most likely to be affected. Female children, however, tend to have more likely progression into adolescence. Quality-of-life indices can aid in screening for vocal nodules whereas stroboscopy, and possibly, ultrasound are required for definitive diagnosis. SUMMARY: Management has not significantly changed over time and should begin with conservative behavioral and environmental modifications along with voice therapy in those more severely impacted. Though immediate outcomes vary somewhat depending on management direction, the overall prognosis seems to be good even with lack of intervention. It is most critical to ensure a definitive diagnosis, and offer management therapies that are appropriate for the level of impact the vocal nodules have on communication and voice production in the child. PMID- 30300212 TI - Recurrent laryngeal nerve reinnervation: is this the standard of care for pediatric unilateral vocal cord paralysis? AB - PURPOSE OF REVIEW: Ansa to recurrent laryngeal nerve reinnervation, otherwise known as a nonselective laryngeal reinnervation (NSLR), is growing in popularity for the management of pediatric unilateral neuronal vocal fold movement impairment (VFMI). In this chapter, we will review the current treatment options for neuronal VFMI and role that NSLR plays in the treatment algorithm. RECENT FINDINGS: In 2018, Bouhabel and Hartnick published a survey of fellowship trained pediatric otolaryngologists and found an increasing comfort level with NSLR. Respondents felt that NSLR resulted in favorable subjective and objective postsurgical voice outcomes. Furthermore, NSLR may decrease the risk of aspiration in children with neuronal VFMI. Although NSLR appears to work, the voice results are not perfect for all children. Further work is being done to understand which preoperative variables, such as age, time from injury, and preop laryngeal electromyography, may predict a better voice outcome. SUMMARY: A variety of treatment options exist for unilateral neuronal VFMI. Recent data and developments demonstrate the effectiveness of reinnervation as a potential first line surgical intervention in children with unilateral neuronal VFMI.

AB - BACKGROUND: Sub-optimal adherence to antiretroviral therapy among people living with HIV/AIDS (PLWHA) who use illicit drugs remains an ongoing health concern. Although health outcomes associated with adherence self-efficacy have been well documented, there is dearth research exploring the predictors of this construct. This study sought to identify possible determinants of adherence self-efficacy among a cohort of PLWHA who use illicit drugs. METHODS: From December 2004 to May 2014, we collected data from the AIDS Care Cohort to evaluate Exposure to Survival Services, a prospective cohort of adult PLWHA who use illicit drugs in Vancouver, Canada. We used multivariate generalized estimating equations (GEE) analyses to identify longitudinal factors independently associated with higher adherence self-efficacy. RESULTS: Among 742 participants, 493 (66.4%) identified as male and 406 (54.7%) reported white ancestry. In multivariate GEE analysis, older age at ART initiation (Adjusted Odds Ratio [AOR] = 1.02, 95% confidence interval [CI]: 1.00 - 1.03) and recent year of baseline interview (AOR = 1.08, 95% CI: 1.05 - 1.11) were independently associated with higher adherence self efficacy, while homelessness (AOR = 0.78, 95% CI: 0.65 - 0.94); >= daily crack smoking (AOR = 0.81, 95% CI: 0.68 - 0.96); experienced violence (AOR = 0.82, 95% CI: 0.69 - 0.98), and childhood abuse (AOR = 0.75, 95% CI: 0.60 - 0.92) were negatively associated. CONCLUSIONS: These findings highlight the potential role that personal and contextual factors can play in predicting levels of ART adherence self-efficacy. Future research should seek to identify and validate strategies to optimize adherence self-efficacy. PMID- 30300215 TI - Two Surgeon Approach for Complex Spine Surgery: Rationale, Outcome, Expectations, and the Case for Payment Reform. AB - There is an increased trend in complex spine deformity cases toward a two attending surgeon approach, but the practice has not become widely accepted by payers. Multiple studies have shown that spine surgery complications increase with the duration of case, estimated blood loss, and use of transfusions, as well as in certain high-risk populations or those requiring three-column osteotomies. Dual-surgeon cases have been shown to decrease estimated blood loss, transfusion rate, surgical times, and therefore complication rates. Although this practice comes at an uncertain price to medical training and short-term costs, the patient's quality of care should be prioritized by institutions and payers to include dual-surgeon coverage for these high-risk cases. Because we enter an era where the value of spine care and demonstrating cost-effectiveness is essential, dual surgeon attending approaches can enhance these tenets. PMID- 30300216 TI - Optimizing Clinical Use of Biologics in Orthopaedic Surgery: Consensus Recommendations From the 2018 AAOS/NIH U-13 Conference. AB - Concern that misinformation from direct-to-consumer marketing of largely unproven "biologic" treatments such as platelet-rich plasma and cell-based therapies may erode the public trust and the responsible investment needed to bring legitimate biological therapies to patients have resulted in calls to action from professional organizations and governing bodies. In response to substantial patient demand for biologic treatment of orthopaedic conditions, the American Academy of Orthopaedic Surgeons convened a collaborative symposium and established a consensus framework for improving and accelerating the clinical evaluation, use, and optimization of biologic therapies for musculoskeletal diseases. The economic and disease burden of musculoskeletal conditions is high. Of the various conditions discussed, knee osteoarthritis was identified as a "serious condition" associated with substantial and progressive morbidity and emerged as the condition with the most urgent need for clinical trial development. It was also recognized that stem cells have unique characteristics that are not met by minimally manipulated mixed cell preparations. The work group recommended that minimally manipulated cell products be referred to as cell therapy and that the untested and uncharacterized nature of these treatments be clearly communicated within the profession, to patients, and to the public. Minimum standards for product characterization and clinical research should also be followed. A framework for developing clinical trials related to knee OA was agreed upon. In addition to recommendations for development of high-quality multicenter clinical trials, another important recommendation was that physicians and institutions offering biologic therapies commit to establishing high-quality patient registries and biorepository-linked registries that can be used for postmarket surveillance and quality assessments.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30300217 TI - Management of Developmental Dysplasia of the Hip in Infants up to Six Months of Age: Intended for Use by General Pediatricians and Referring Physicians. AB - The American Academy of Orthopaedic Surgeons has developed the Appropriate Use Criteria (AUC) for the Management of Developmental Dysplasia of the Hip in Infants up to Six Months of Age: Intended for Use by General Pediatricians and Referring Physicians. Evidence-based information, in conjunction with the clinical expertise of physicians, was used to develop the criteria to improve patient care and obtain best outcomes while considering the subtleties and distinctions necessary in making clinical decisions. The Management of Developmental Dysplasia of the Hip in Infants up to Six Months of Age: Intended for Use by General Pediatricians and Referring Physicians AUC clinical patient scenarios were derived from indications typical of patients presenting with developmental dysplasia of the hip in clinical practice. The 24 patient scenarios and four treatments were developed by the Writing Panel, a group of clinicians who are specialists in this AUC topic. Next, a separate multidisciplinary, Voting Panel (made up of specialists and nonspecialists) rated the appropriateness of treatment of each patient scenario using a 9-point scale to designate a treatment as Appropriate (median rating, 7 to 9), May be Appropriate (median rating, 4 to 6), or Rarely Appropriate (median rating, 1 to 3).

PMID- 30300219 TI - Individual Treatment of Delayed Distal Biceps Tendon Rupture: Case Report and Literature Review. AB - INTRODUCTION: Complicated elbow injuries (elbow injuries with bone and soft tissue injury) with distal biceps tendon ruptures (DBTRs) are not uncommon. There are several treatment modalities in different situations of injuries. In this article, we reported 3 successful individual treatments of delayed DBTR with complicated elbow injuries. MATERIALS AND METHODS: Three cases of complicated elbow injuries treated between 2010 and 2016 were reviewed. The delayed DBTR cases were summarized and treated. Mayo Elbow Performance Score value, range of motion, and visual analog scale score were used to assess outcomes after a minimum follow-up of 12 months. RESULTS: All 3 patients were male, aged 47 to 54 years (mean, 49.6 years). Patients received surgical treatments. After a mean follow-up of 13.7 months, in cases 1 and 2, Mayo Elbow Performance Score values improved by 50% and 100%, elbow flexion-extension arc were 115 degrees and 110 degrees, pronation-supination arc were 130 degrees and 120 degrees. Arthrodesis case reported pain relief; visual analog scale score for pain was 0 to 1. No postoperative complications were observed, and all patients were satisfied with the results. CONCLUSIONS: Individual treatment is advised in DBTR with complicated elbow injuries. Secondary treatment of DBTR can achieve satisfactory results using individual strategies depending on patients' overall condition. PMID- 30300220 TI - Application of Concatenated Arterialized Venous Flaps in Finger Reconstruction. AB - Venous flaps from the distal volar forearm are said to be suitable flaps for finger reconstruction. The pliability of the forearm venous flap makes it easy to follow the curvature of the finger contour. The thickness of the flap makes it appropriate as a flap for finger resurfacing. Following the venous network at the palmar forearm, diverse patterns of the venous flaps can be designed. This article describes the use of a 2-concatenated paddle, flow-through arterialized venous flap design for simultaneous resurfacing of 2 separate defects on a single digit. A technique that can be used to reduce postoperative venous congestion will be highlighted in this article. PMID- 30300221 TI - Mechanical Dilation With a Nylon Monofilament for 0.1-mm Anastomoses. AB - Despite advances in supermicrosurgical techniques, the ability to anastomose vessels with a diameter of less than 0.2 mm remains limited. One of the reasons for this limitation is that the dilation methods currently available, such as inserting the tip of a microforceps into the lumen or topical application of a vasodilator such as papaverine hydrochloride or xylocaine spray, are not effective in very small vessels. To overcome this problem, we have developed a method whereby nylon monofilaments are placed inside the vessel lumen to act as a dilator. Using this method, a smaller nylon monofilament is inserted into the vessel as a guide before inserting a larger nylon monofilament as a dilator. After the smaller guide monofilament has been inserted, it is then much easier to insert another monofilament for dilation, even if it is a larger one. Using this method, even a vessel with a diameter of less than 0.1 mm could be dilated to greater than 0.2 mm. The dilator monofilament can also be used as an intravascular stent in the anastomosis. We have found that anastomosis of vessels with a diameter of less than 0.1 mm is possible using this method. In our experience, the immediate patency rate has been 100%. We believe mechanical dilation with a nylon monofilament is helpful for supermicrosurgery and even ultramicrosurgery. PMID- 30300222 TI - Readability, Suitability, and Complexity of Online Resources for Lower Extremity Reconstruction. AB - BACKGROUND: Surgical options for lower extremity reconstruction frequently include a decision between autologous free flap reconstruction and amputation. Patients rely on health education materials for information before making treatment decisions. This study evaluates the quality of online health information for lower extremity reconstruction. METHODS: We identified the top 10 Web sites for "leg amputation" and "leg free flap reconstruction." Three validated tools were used to evaluate literacy demand of materials, including (1) the Simple Measure of Gobbledygook for readability; (2) the Peter Mosenthal and Irwin Kirsch readability formula for complexity of nonprose materials such as list, graphs, charts; and (3) the Centers for Disease Control and Prevention's Clear Communication Index (Index). Differences in mean between the 2 groups were compared using Student t test. RESULTS: Average Simple Measure of Gobbledygook reading grades approximated 12th-grade level and were similar between the 2 groups. This is above the recommended level of sixth-grade health literature. Complexity scores for nonprose materials of these groups were within recommended range and corresponded to very low complexity at a fourth- to seventh-grade level. The Centers for Disease Control and Prevention index was higher for amputation literature compared with free flap reconstruction (70% vs 54%), but the difference was not statistically significant. CONCLUSIONS: Overall, online health resources for lower extremity amputation and free flap reconstruction do not meet the standard for quality and accessible health information. Free flap reconstruction resources are scarce and complex. Patients facing decisions about extremity reconstruction may not have appropriate online health resources available to them to make informed decisions. PMID- 30300223 TI - Cross-sectional Area Just Proximal to the Carpal Tunnel According to the Ulnar Variances: Positive Ulnar Variance and Carpal Tunnel Syndrome. AB - PURPOSE: We evaluated the relationship between the area around the distal radioulnar joint according to the ulnar variances and the cross-sectional area using magnetic resonance imaging (MRI) scans in this prospective study of patients with carpal tunnel syndrome (CTS). METHODS: From among a total of 243 patients who had been diagnosed with CTS between March 2012 and February 2017 at our hospital, 41 patients with positive ulnar variance were enrolled in group 1. As control groups, 39 healthy volunteers who underwent MRI evaluations were included in group 2 (neutral ulnar variance) and group 3 (negative variance). Basic demographic data, including age, sex, and body mass index, were recorded for all 3 groups. An area encompassing the contents of carpal tunnel (nerves/tendons) was designated as area "A," and the area just beneath the subcutaneous fat was designated as area "B" at the levels of the lunate (L) and pisiform (P) on axial MRI. Ratios of these areas ("A/B at L" and "A/B at P") were evaluated in terms of their correlations with ulnar variance. RESULTS: Mean age, sex, and body mass index were not statistically different among the groups, respectively. Within each group, there was no difference between "A/B at L" and "A/B at P," respectively. When comparing the 3 groups, "A/B at L" and "A/B at P" were all significantly decreased in group 1 than in other groups. Regardless of the group, ulnar length negatively correlated with both "A/B at L" and "A/B at P" ratios. CONCLUSIONS: We found a positive relationship between decreased cross sectional area around the distal radioulnar joint and positive ulnar variance on radiologic investigation. These findings show the importance of variance in the positive ulna variance to the development of CTS. PMID- 30300224 TI - Comparative Study of Choke Vessel Reconstruction With Single and Multiple Perforator-Based Flaps on the Murine Back Using Delayed Surgery. AB - OBJECTIVE: Choke vessels, vascular anastomosis between adjacent angiosome, play an important role in flap expansion and survival. Here we established a flap model with single and multiple perforators to detect and compare the changes in choke vessels, discuss the effect of hemodynamics on the vascular morphology, and explore the underlying mechanism. METHODS: One hundred mice (7-8 weeks) were subjected to a "choke zone" surrounded by 4 perforators on their backs. Delayed surgery was performed by the ligation of 1, 2, or 3 perforators to establish flap models. The blood flow of the choke zone was measured by laser Doppler flowmetry preoperatively and 6 hours and 1, 3, 5, and 7 days. The morphological changes of choke vessels in the choke zone were observed by gross and histological analyses. Levels of angiogenesis-related markers such as endothelial nitric oxide synthase (eNOS), metalloproteinase 2, hypoxia-inducible factor 1alpha (HIF-1alpha), and intercellular adhesion molecule 2 (ICAM-2) were detected by Western blotting and enzyme-linked immunosorbent assay. RESULTS: Blood flow and microvascular count were obviously increased postoperatively and peaked and were maintained for 1 week (P < 0.01). Meanwhile, the diameters of the choke vessels expanded. The eNOS level was increased at 7 days (P < 0.05); however, the enzyme-linked immunosorbent assay results showed that the HIF-1alpha and ICAM-2 levels were decreased at 7 days. CONCLUSIONS: (1) The delayed surgery that kept a single perforator had the greatest impact on the choke zone. (2) Changes in choke vessels were closely related to the shear stress caused by enhanced blood perfusion after surgery. (3) Choke vessel growth was regulated by eNOS, metalloproteinase 2, HIF-1alpha, and ICAM-2. PMID- 30300225 TI - The Influence of Patient Exposure to Breast Reconstruction Approaches and Education on Patient Choices in Breast Cancer Treatment. AB - BACKGROUND: The landscape of surgical and medical management and patient choices for breast cancer treatment changes as breast reconstruction and oncoplastic approaches improve and diversify. Increased access to breast reconstruction, in addition to patient education, influences the breast cancer patient. Therefore, the examination of the possible impact of reconstructive surgery on all stages of the breast cancer management per se seemed timely. METHODS: Plastic surgery consults were arranged for 520 new patients diagnosed with breast cancer (2012 2016) including patients with noninvasive breast cancer but at high risk of further cancer development. To test the plastic surgery impact on patient choices regarding the management of the cancer, a subset of 90 patients was identified to test the plastic surgery impact on patient choices. These patients were referred to plastic surgery, following the first round of consultations by surgical and medical oncologists with only the preliminary oncological management plan defined. After a plastic surgery consultation, but prior to finalization of the overall oncological management plan, they were surveyed on the subject of modification of their personal choices and requests pertaining to their cancer management. RESULTS: In this subset of 90 patients 40 (44%) returned to their surgical or medical oncologist considering changes of the primary management plan after their plastic surgery consultation. Twenty-six (28%) ultimately altered their plan, and the following patient-driven changes were made: mastectomy as opposed to lumpectomy (18 patients [20%]), contralateral prophylactic mastectomy (11 patients [12%]), nipple/areola removal as opposed to nipple/areola sparing suggested by the oncologists (5 patients [6%]), oncoplastic breast reduction as part of lumpectomy (5 patients [6%]), and other modifications (3 patients [3%]). CONCLUSIONS: Decisions for altering the preliminary oncologic plan or choosing a specific alternative (eg, lumpectomy plus radiation vs mastectomy) resulted from patient education on (1) reconstructive options, (2) aesthetic pitfalls and results. and (3) their interfacing with the oncological outcomes. Ultimately, plastic surgeons influence the multispecialty breast cancer management and patient decision-making process. Therefore, oncological literacy for plastic surgeons is essential to provide state-of-the-art breast cancer care and avoidance of suboptimal patient decisions.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30300226 TI - Pedicled Thoracodorsal Artery Perforator and Muscle-Sparing Latissimus Dorsi Flaps in the Axillary Reconstruction After Hidradenitis Suppurativa Excision: Functional and Aesthetic Issues. AB - BACKGROUND: Wide axillary reconstruction after hidradenitis suppurativa (HS) excision still represents a great challenge. Thoracodorsal artery perforator flap is one of the most reliable local reconstructive techniques. Although its anatomy and harvesting technique have been well described, specific reconstructive criteria still lack. The aim of this study was to help surgeons in planning axillary reconstruction on flaps based on the thoracodorsal artery. METHODS: Twelve patients affected by HS at Hurley stage III underwent wide "en block" excision and immediate reconstruction with 15 local thoracodorsal artery perforator flaps and 2 muscle-sparing latissimus dorsi flaps. A thorough chart review has been performed with preoperative and postoperative photographic documentations. Early and late complications have been analyzed. RESULTS: A total of 15 perforator flaps on thoracodorsal artery and 2 muscle-sparing latissimus dorsi flaps have been raised. The early complication rate was 29%, whereas the late complication rate was 35%. Except for one, all patients declared they were satisfied or highly satisfied from both aesthetic and functional points of view. Analyzing specific aspects, we have described several important details to consider for the reconstruction of the axilla. Through a retrospective analysis, we have classified HS axillary patients into 4 categories to better plan surgical reconstruction. CONCLUSIONS: Axillary reconstruction is still a plastic surgery challenge. Peculiar surgical details should be considered when approaching this area. This new classification may help young surgeons during the reconstructive phase. PMID- 30300227 TI - Maternal Tobacco Exposure and Development of Orofacial Clefts in the Child: A Case-Control Study Conducted in Pakistan. AB - INTRODUCTION: The purpose of this study was to evaluate the association between maternal tobacco exposure and development of orofacial clefts (OFCs) in the child in a Pakistani population. METHODS: A case-control study was conducted at the Cleft Hospital and Bashir Hospital in Gujrat, Pakistan, from December 2015 to December 2016. All new cases of OFC at the Cleft Hospital were included. Patients at Bashir Hospital younger than 3 years and without congenital malformations were selected as control subjects. Risk factors associated with OFC were identified through bivariate analyses. Multiple logistic regression was then performed to calculate adjusted odds ratios (ORs) of developing OFC according to various risk factors. RESULTS: The study included 297 patients with OFC and 131 control subjects. Upon univariable analysis, the following were associated with OFC: maternal tobacco exposure (P < 0.001), complications during pregnancy (P < 0.001), maternal hypertension (P = 0.01), mother not on physician-recommended medications (P < 0.001), mother not receiving vaccinations (P < 0.001), consanguineous marriage (P < 0.001), and lower socioeconomic status (P < 0.001). Upon multivariable analysis, having a smoking parent (OR, 1.89; 95% confidence interval [CI], 1.10-3.26), complications during pregnancy (OR, 2.36; 95% CI, 1.43 3.88), and consanguineous marriage (OR, 1.79; 95% CI, 1.13-2.85) were associated with increased odds of development of OFC; receiving vaccinations (OR, 0.31; 95% CI, 0.16-0.63) and higher socioeconomic status (OR, 0.20; 95% CI, 0.05-0.74) were protective. CONCLUSIONS: Patients with OFC were nearly twice as likely to have a parent who smokes as those without. Efforts to reduce tobacco consumption among prospective parents, such as perinatal tobacco cessation counseling programs, should be evaluated in this population. PMID- 30300228 TI - The Effects of Electrical Stimulation Parameters in Managing Spasticity after Spinal Cord Injury: A Systematic Review. AB - Controversial findings about the effects of neuromuscular electrical stimulation (NMES) and functional electrical stimulation (FES) in managing spasticity have been raised after spinal cord injury (SCI). A systematic review was conducted to identify the range of the stimulation parameters that may alleviate spasticity. Three independent reviewers searched Medline (PubMed), web of knowledge, Scopus, Cochrane Central, Virtual Health Library and Physiotherapy Evidence Database until January 2018. Inclusion criteria were applications of NMES/FES on the lower extremity muscles, stimulation parameters (frequency, pulse duration and amplitude of current) and measures of spasticity after SCI. The primary outcome was spasticity as measured by the Modified Ashworth Scale and the secondary outcome was spasticity assessed by other indirect measures. Twenty-three clinical and non-clinical trials were included with 389 subjects. NMES/FES provided reductions in spasticity by 45-60% with decrease in electromyography activity and increase in range of motion after SCI. The identified stimulation parameters were frequency of 20-30Hz, pulse duration of 300-350 MUs and amplitude of the current > 100 mA. NMES/FES provides an effective rehabilitation strategy in managing spasticity. However, a recommendation of the stimulation parameters cannot be accurately assumed due to high variability in the methodology, design and heterogeneity of the included studies. PMID- 30300229 TI - Physiotherapy in postinfection injury to cranial nerves III, IV, and VI: a case study. AB - The patient with bacterial infection sequelae in the form of damage to cranial nerves (CN) III, IV, and VI was followed-up. He had exhibited clinical and radiographic signs of paranasal sinusitis. Prior to his physiotherapy, the patient received standard treatment with natural and synthetic antibiotics and steroids. After acute signs of infection resolved without any functional improvement, the patient was referred to a rehabilitation unit to undergo neuromuscular re-education of the paralyzed extraocular muscles. Periorbital hydrocortisone iontophoresis and visuomotor exercises with intense ideomotor stimulation led to complete and rapid resolution of extraocular muscle paralysis and diplopia. Physiotherapy can be an effective treatment of choice after failed pharmacological treatment in patients with damage to CN III and VI. It has many theoretical advantages, including non-invasiveness and avoidance of first-pass metabolism of drugs administered systemically. PMID- 30300230 TI - A STIMULUS-RESPONSE FRAMEWORK TO INVESTIGATE THE INFLUENCE OF CONTINUOUS VERSUS INTERVAL WALKING EXERCISE ON SELECT SERUM BIOMARKERS IN KNEE OSTEOARTHRITIS. AB - OBJECTIVE: Compare changes in the concentration of serum biomarkers in response to continuous versus interval walking exercise in participants with knee osteoarthritis (OA). DESIGN: A two-phase sequential design. Twenty-seven participants with unilateral knee OA completed two separate treadmill walking sessions: 1) continuous 45-minute walking exercise and 2) three 15-minute bouts of walking exercise separated by 1-hour rest periods for a total of 45 minutes in an interval format. Participants reported their knee pain using the numeric pain rating scale and serum levels of biomarkers associated with tissue turnover [cartilage oligomeric matrix protein (COMP)], inflammation [Tumor necrosis factor alpha (TNF-alpha)] and pain [neuropeptide-Y (NPY)] were evaluated at baseline and every 15 minutes for both conditions. RESULTS: Continuous walking resulted in a cumulative increase in COMP concentration up to 45 minutes, whereas interval walking was associated with return of COMP concentrations back to baseline at 45 minutes. There were no significant changes in TNF-alpha and NPY concentration during walking. There was a significant increase in pain compared to baseline in the continuous walking regimen only. CONCLUSION: Incorporating rest breaks in walking regimens may impact the potential deleterious effects of longer continuous bouts on the knee joint as well as limit pain during exercise. PMID- 30300231 TI - Measuring the Impact of Research Using Conventional and Alternative Metrics. AB - Bibliometrics utilize statistical methods to measure the scholarly impact of publications. Bibliometrics are categorized as conventional metrics (CM) or alternative metrics (AM). CM have often been considered the standard to measure the impact of publication-related scholarship. With the growing popularity of social media (SoMe) and ease of instantaneous distribution of information globally, AM have become an important complementary measure of scholarly activity. Bibliometrics may provide a standard performance measurement that may be used for tenure and/or promotion among academic institutions. The alternative metric industry has shown considerable growth with increasingly improved algorithms working towards standardization. Together, CM and AM may synergistically complement each other to provide an accelerated translation from research to clinical care that may lead to tremendous benefits in patients. All physicians and other healthcare professionals should receive training in bibliometrics and understand the potential impact of professional social media use. PMID- 30300232 TI - Electrical stimulation in the treatment of hemiplegic shoulder pain: a meta analysis of randomized controlled trials. AB - : OBJECTIVETo determine the effect of electrical stimulation (ES) in the treatment of hemiplegic shoulder pain (HSP).DESIGNEight databases were systematically searched for randomized controlled trials (RCTs) with a treatment duration of at least two weeks comparing ES with sham stimulation or no stimulation for patients with HSP. Shoulder pain on the hemiplegic side after stroke at baseline was required at study selection. The overall effects of ES were calculated using a meta-analytic method. RESULTS: Six studies were included. The pooled data indicated that ES may have a positive effect for patients with HSP on pain reduction (n=193; SMD [standardized mean difference] = -1.89; 95% CI [-3.05, -0.74]) and pain-free external rotation (PFER) (n=164; WMD [weighted mean difference] = 18.92; 95% CI [7.00, 30.84]). Meta-analysis also showed better recovery of activities of daily living (ADL) independence in patient groups receiving ES (n=167; WMD = 8.96; 95% CI [5.26, 12.66]). CONCLUSIONS: ES may be an effective pain management methodology for hemiplegic shoulders and may contribute to pain-free range of external rotation as well as ADL recovery. However, these results should be interpreted with caution, given the low number of selected studies and risk of potential bias. PMID- 30300233 TI - Is Occupational Therapy After Hip Fracture Surgery Effective in Improving Function? A Systematic Review and Meta-analysis of Randomized Controlled Studies. AB - OBJECTIVES: This study is aimed to evaluate whether occupational therapy (OT) improves activities of daily living (ADL) and overall physical functioning of patients after hip fracture surgery (HFS).PubMed-Medline, Embase, and Cochrane Library databases.We searched for randomized controlled trials comparing OT with comprehensive postoperative care (without OT) after HFS. A pairwise meta-analysis using fixed- and random-effects models was performed. The primary outcome of interest was performance of ADL assessed in any manner. The secondary outcomes were other functional parameters: 1) physical function; 2) health perception and emotion; and 3) fall occurrence. Effect sizes were computed as standardized mean differences (SMDs) with 95% confidence intervals (CIs). RESULTS: Five randomized controlled trials including a total of 524 participants were retrieved. There was a trend towards improvement in ADL, physical function, and fall occurrence, these changes were not significant. However, health perception and patient emotions improved significantly in the OT group (SMD=0.391; 95% CI, 0.104-0.678; p=0.008). CONCLUSION: OT after HFS seems to improve overall function. Indeed, the positive effects of OT on health perception and emotions were evident. Therefore, OT can be suggested in comprehensive rehabilitation programs after HFS.

PMID- 30300237 TI - Computerized exposure therapy for Spider Phobia: Effects of cardiac timing and interoceptive ability on subjective and behavioral outcomes. AB - OBJECTIVE: Spider phobia is a common form of anxiety disorder for which exposure therapy is an effective first-line treatment. Motivated by the observed modulation of threat processing by afferent cardiac signals; we tested the hypothesis that interoceptive information concerning cardiovascular arousal can influence the outcomes of computerised exposure therapy for spider phobia. METHOD: Fifty-three normal healthy participants with high spider phobia scores underwent one of three modified computerised exposure protocols, defined by the timing of exposure to brief spider stimuli within the cardiac cycle: Systole (during afferent baroreceptor firing); Diastole (during baroreceptor-quiescent interbeat interval); Random (non-contingent on cardiac cycle). Outcomes were judged on phobic and anxiety measures and physiological data (skin conductance). Subjects were also rated on interoceptive accuracy. RESULTS: Mancova analysis showed that timing group affected the outcome measures (F(10,80)=2.405, p=0.015) and there was a group interaction with interoception ability (F(15,110)=1.808, p=0.045). Subjective symptom reduction (SPQ) was greatest in the Systolic group relative to the other two groups (Diastolic (t=3.115, ptukey=0.009); Random (t=2.438, ptukey=0.048), with greatest reductions in those participants with lower interoceptive accuracy. Behavioural aversion (BAT) reduced more in cardiac contingent groups than the non-contingent (Random) group (Diastolic (t=3.295, ptukey=0.005); Systolic (t=2.602, ptukey=0.032). Physiological (SCR) responses remained strongest for spider stimuli presented at cardiac systole. CONCLUSION: Interoceptive information influences exposure benefit. The reduction in the subjective expression of fear/phobia is facilitated by 'bottom-up' afferent signals; while improvement in the behavioural expression is further dependent on 'top-down' representation of self-related physiology (heart rhythm). Individual interoceptive differences moderate these effects, suggesting means to personalise therapy. PMID- 30300238 TI - Bereavement, self-reported sleep disturbances and inflammation: Results from Project HEART. AB - OBJECTIVE: Spousal bereavement is linked to increased mortality and morbidity from inflammatory conditions. It also has a significant impact on sleep disturbances. Evidence from experimental studies indicates that chronic stress may prime individuals to have an exaggerated inflammatory response to acute stress. In this study, we examined the association between self-reported sleep disturbances and inflammation after adjusting for depressive symptoms, and determined whether this association varies by bereavement status (bereaved individuals vs. controls). METHODS: Participants included 54 bereaved individuals and 47 controls with a mean age of 67.12 (SD=12.11). Inflammation was measured using C-reactive protein (CRP). Self-reported sleep disturbances were measured using the Pittsburgh Sleep Quality Index (PSQI). Depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale (CES-D). RESULTS: Sleep disturbances were not associated with elevated levels of CRP in the overall group (B=0.030, standardized beta=0.122, 95% Confidence Intervals [CI]=-0.027 - 0.087, p=0.299) after adjusting for depressive symptoms. Results indicated, however, that bereavement moderated the association between inflammation and sleep disturbances (B=0.104, beta=0.517, 95% CI=0.009 - 0.198, p=0.032). Stratified analyses demonstrated that these associations differed across groups. Associations were significant among bereaved individuals (B=0.104, beta=0.406, 95% CI=0.013 - 0.196, p=0.026) and not controls (B=-0.016, beta= 0.066, 95% CI=-0.096 - 0.065, p=0.690). CONCLUSIONS: These findings provide preliminary evidence that bereavement moderates the association between self reported sleep disturbances and inflammation. Future studies should examine the course of sleep disturbances following bereavement and establish whether objective sleep has differential associations with inflammation among bereaved adults. PMID- 30300239 TI - Multiple sclerosis: clinical aspects. AB - PURPOSE OF REVIEW: Multiple sclerosis is a chronic, predominantly immune-mediated disease of the central nervous system, and one of the most common causes of neurological disability in young adults globally. This review will discuss the epidemiology, diagnosis, disease course, and prognosis of multiple sclerosis and will focus on recent evidence and advances in these aspects of the disease. RECENT FINDINGS: Multiple sclerosis is increasing in incidence and prevalence globally, even in traditionally low-prevalence regions of the world. Recent revisions have been proposed to the existing multiple sclerosis diagnostic criteria, which will facilitate earlier diagnosis and treatment in appropriate patients. Classifying multiple sclerosis into distinct disease phenotypes can be challenging, and recent refinements have been proposed to clarify existing definitions. The prognosis of multiple sclerosis varies substantially across individual patients, and a combination of clinical, imaging, and laboratory markers can be useful in predicting clinical course and optimizing treatment in individual patients. SUMMARY: A number of recent advances have been made in the clinical diagnosis and prognostication of multiple sclerosis patients. Future research will enable the development of more accurate biomarkers of disease categorization and prognosis, which will enable timely personalized treatment in individual multiple sclerosis patients. PMID- 30300240 TI - Are molecular subgroups of medulloblastomas really prognostic? AB - PURPOSE OF REVIEW: Medulloblastoma is no more a unique disease. Clinical and biologic classification used so far are challenged by molecular classification(s). Following the consensus article that described four molecular groups of medulloblastoma in 2012, several articles in 2017 provided more relevant classifications that may impact on further clinical trial design. RECENT FINDINGS: Though wingless (WNT) and sonic hedgehog (SHH) are defined by the activation of their respective pathways, the age and type of activation define various subgroups with specific features and outcome. Groups 3 and 4 remain ill defined. The whole population of medulloblastoma may be divided in 12 subgroups: WNTalphabeta, SHHalphabetagammadelta, group 3alphabetagamma and group 4alphabetagamma. The paediatric population may be divided in seven subgroups: WNT, SHH of infants and children, and low-risk and high-risk groups 3 and 4. SHH of infants may be divided as iSHH-I vs. iSHH-II that have different prognosis. Moreover, specific drivers of groups 3 and 4 were reported. SUMMARY: These findings have and will have direct implications on the conception of clinical trials. Low-risk groups will benefit from less toxic therapies, and high-risk groups will benefit from targeted therapies. PMID- 30300241 TI - Is whole-brain radiotherapy still a standard treatment for primary central nervous system lymphomas? AB - PURPOSE OF REVIEW: In primary central nervous system lymphomas (PCNSL), optimal therapy remains to be established, and the role of whole-brain radiotherapy (WBRT) is a matter of debate. With radiation alone, transient responses and clinical improvement are frequent, but long-term disease control is exceptional. WBRT has been considered possible consolidation therapy after high-dose methotrexate (HDMTX)-based initial chemotherapy. This strategy has been questioned due to a high risk of delayed neurotoxicity after combined treatment. This review analyses the current role of WBRT in PCNSL. RECENT FINDINGS: Neither in retrospective analyses nor in randomized trials, an overall survival benefit with WBRT in addition to HDMTX-based initial chemotherapy could be found. On the other hand, a recent randomized trial did not show superiority of consolidation with high-dose chemotherapy followed by autologous stem-cell transplantation to consolidation WBRT after initial HDMTX-based polychemotherapy. This finding, however, is probably due to an intense initial therapy and to a small number of patients having reached consolidation and randomization to WBRT vs. high-dose chemotherapy followed by autologous stem-cell transplantation. SUMMARY: The current role of WBRT in PCNSL is confined to patients who cannot tolerate chemotherapy or have failed it. WBRT should not routinely be used for consolidation of HDMTX-based chemotherapy due to lack of evidence of efficacy as additional treatment and due to a high risk of neurotoxicity.

PMID- 30300243 TI - Mycobacterium chimaera infections following cardiac surgery in Italy: results from a National Survey Endorsed by the Italian Society of Cardiac Surgery. AB - AIMS: A global outbreak of Mycobacterium chimaera infections following cardiac surgery and linked to contaminated heater-cooler units (HCUs) is currently ongoing. Neither the status of this outbreak in Italy nor the mitigation strategies adopted by adult cardiac surgery units (ACSUs) are currently known. In 2017, the Italian Society of Cardiac Surgery launched a national survey among the Italian ACSU to shed some light on this issue. METHODS: In Italy, there are 90 ACSUs across 20 regions. From May to November 2017, these ACSUs were surveyed collecting data on patients diagnosed with MC infections, ACSU workload, HCU models in use and control measures adopted in the operatory room. RESULTS: The response rate was 87.8%. The median number of cardiac procedures at each ACSU was 450/year [interquartile range (IQR) 350-650 procedures/year], and nationally, the number of procedures/year exceeded 40k. In Italy, seven patients with M. chimaera infections following cardiac procedures have been reported since 2015: all had aortic or valvular surgery as the first procedure; the median latency between the first operation and the infection was 2 years (IQR 2-3.25). Mortality for patients requiring redo cardiac surgery was 50%. M. chimaera infections risk was 0.4-1 patient every 1000 cardiac procedures. The most common HCU model in Italy is the 3T HCU (70.9%). The most common control measures adopted included implementing new HCU disinfection protocols, using sterile or filtrated water in the HCU and displacing HCU fans away from the patient: HCU replacement and microbiology testing were instead infrequent. CONCLUSION: In Italy, the risk of contracting M. chimaera infections and the mortality reported are in line with other European countries, but significant heterogeneity exists on the mitigation strategies adopted to prevent further M. chimaera inoculations, suggesting the development of national guidelines. PMID- 30300244 TI - Results of new-generation intrapericardial continuous flow left ventricular assist devices as a bridge-to-transplant. AB - AIMS: We analysed the outcomes with the use of a new-generation continuous-flow left ventricular assist device (CF-LVAD) as a bridge-to-transplant (BTT). MATERIALS AND METHODS: We included all patients implanted with an intrapericardial CF-LVAD as BTT, between January 2012 and December 2016. Primary outcomes were overall survival, survival on waiting list and postheart transplant (HTx) survival. The outcomes after HTx were compared with those of a contemporary cohort of patients transplanted without previous CF-LVAD (No-LVAD group, n = 73). RESULTS: We included 53 patients with a median age of 52 years (interquartile range: 43-59 years). Seventy-two percent were in INTERMACS profile 1-2 before implant; all entered the HTx waiting list after receiving the CF-LVAD. HTx was performed in 42 (79%) cases (LVAD group). Overall estimated survival (considering both pre-HTx and post-HTx) was 89% [95% confidence interval (CI) 81-98%] at 1 year and 80% (CI 70-92%) at 2 years. The estimated survival on waiting list was 91% (CI 80-100%) at 6 months, whereas the 1-year estimated post-HTx survival was 88% (CI 79-98%). The Kaplan-Meier curves of survival after HTx of LVAD versus No LVAD group were comparable (log-rank P = 0.54), as well as the rates of post-HTx adverse events. A multivariable model of survival after HTx, accounting for the most relevant patient characteristics, identified LVAD use as a significant protective factor [LVAD versus No-LVAD hazard ratio 0.22 (CI 0.06-0.91)]. CONCLUSION: The use of new-generation intrapericardial CF-LVADs as a BTT resulted, in our series, in satisfactory pre-HTx and post-HTx outcomes. PMID- 30300245 TI - Tenodesis of the Ulnotriquetrum Ligament to the Fovea for a Triangular Fibrocartilage Complex Tear. AB - We developed a novel procedure to treat a triangular fibrocartilage complex (TFCC) foveal tear, namely tenodesis of the ulnotriquetrum ligament (UTL) to the fovea. We attempted to reestablish the tension of the palmar radioulnar ligament by the procedure specifically in cases with palmar radius instability relative to the ulna. We used a palmar surgical approach to expose the palmar aspect of TFCC in which the ulnocarpal ligament merges with the palmar radioulnar ligament. UTL was distally excised at a 4 mm width from the triquetrum without disrupting its ligamentous connection to the palmar radioulnar ligament proximally. We pulled out the distal UTL through the bone tunnel from the fovea to ulnar neck. The UTL graft was fixed to the fovea with an interference screw. In 13 cases, this procedure effectively decreased ulnar wrist pain, improved distal radioulnar joint instability, and restored wrist motion and grip strength. PMID- 30300246 TI - Surgical Management of the Posttraumatic Stiff Elbow: A Step-Wise Algorithm for Open Osteocapsular Release. AB - Posttraumatic elbow stiffness is common with the primary indication for contracture release being limited motion that affects functional activities which has not adequately improved after intensive therapy and rehabilitation. Preoperative evaluation focuses on the history of previous nonoperative and/or operative treatment, physical exam with particular attention paid to the status of the ulnar nerve, and imaging consisting of radiographs and computed tomography. There are multiple intrinsic and extrinsic causes of posttraumatic contracture. In general, limitation of motion in one direction can be attributed to a mechanical block and/or opposing contracture or tightness. Open elbow contracture release has been shown to improve motion, patient health status and disability scores with the specific surgical approach based upon the contracture pathology and surgeon preference. A step-wise algorithm is presented for open osteocapsular release. An anterior and posterior release is performed first through a lateral approach with the addition of a medial approach if ulnar nerve dysfunction exists or inadequate release has been obtained from the lateral approach. A previous posterior incision can be utilized by raising full thickness flaps. After release, gentle manipulation is performed and intraoperative stability is assessed with stress testing under fluoroscopy. Postoperatively, pain is managed with an in-dwelling nerve catheter and rehabilitation commences immediately. Significant improvement in range of motion can be expected with adequate surgical release and postoperative rehabilitation. PMID- 30300247 TI - Therapeutic Management of the Posttraumatic Stiff Elbow After Open Osteocapsular Release. AB - Arthrofibrosis is an inevitable consequence of elbow trauma that oftentimes requires surgical release to restore range of motion and function. Although the surgical procedure for elbow osteocapsular release can result in marked improvement in elbow motion, postrelease rehabilitation is paramount to maintaining and even improving the gains achieved in surgery. There are a variety of rehabilitation protocols and modalities that can be implemented that can be divided into an early versus late stage of rehabilitation after surgery. Irrespectively, patient ownership in the rehabilitative process and effective communication between surgeon and therapist are integral in achieving successful outcomes.

AB - : Hypertension is a major risk factor for cardiovascular disease, affecting 1 billion people worldwide. Literature suggests some herbs and spices have cardiovascular benefits, such as decreasing blood pressure; yet evidence is inconsistent. This article reviewed randomized controlled trials investigating effects of herbs and spices on blood pressure in normotensive, pre-hypertensive and hypertensive participants. Ovid Medline, Embase, Biological abstracts, CINAHL and Cochrane Collaboration were systematically searched. After inclusion and exclusion criteria were applied, nine articles were included for analysis. Overall, three of the nine studies reported statistically significant results, including one of the two studies on hypertensive participants and two of the six studies on pre-hypertensive participants. The remaining study was conducted on normotensive participants and reported no change in blood pressure. There is evidence to suggest certain herbs and spices can reduce blood pressure in a hypertensive and pre-hypertensive population and may not induce hypotension in a normotensive population. PMID- 30300252 TI - Combined impact of risk factors on the subsequent development of hypertension. AB - OBJECTIVES: This study aimed to develop a cumulative score composed of seven risk factors: age, resting heart rate, overweight or obesity, dyslipidemia, hyperuricemia, impaired glucose regulation, and impaired estimated glomerular filtration rate (eGFR), to evaluate the risk of new-onset hypertension. METHODS: We retrospectively conducted a cohort study in 23 665 participants free from hypertension at baseline, who attended at least two annual health examinations between 2011 and 2016. We defined hypertension as SBP of 140 mmHg or less and/or DBP of at least 90 mmHg, according to the 2010 Chinese guidelines for the management of hypertension. We computed a composite, individual-level cumulative score incorporating all seven risk factors (no = 0 point; yes = 1 point; total range 0-7 points). Cox regression was used to analyze the association between cumulative score and risk of hypertension. RESULTS: A total of 2305 participants developed hypertension during a median follow-up period of 3.6 years. Compared with participants with 0 points, the adjusted hazard ratios (95% confidence intervals) for the development of hypertension for those with 2, 3, and at least 4 points were 1.61 (1.29-2.02), 2.05 (1.64-2.57) and 2.77 (2.22-3.46), respectively (P trend < 0.001). This association was present after adjustment for sex and baseline blood pressure. CONCLUSION: Age, resting heart rate, overweight or obesity, dyslipidemia, hyperuricemia, impaired glucose regulation, and impaired eGFR were associated with significant risk of new-onset hypertension and when combined there was an accumulation of risk. PMID- 30300253 TI - A Pediatric Nasogastroscope Facilitates Colorectal Endoscopic Stenting. AB - PURPOSE: Endoscopic placement of self-expandable metal stents (SEMSs) to relieve malignant colorectal obstruction has been widely accepted in clinical practice. Despite increasing experience, early and late complications occur with an incidence ranging from 4% to 20%. MATERIALS AND METHODS: We have adopted a modification in the technique. A pediatric nasogastroscope (4.8 mm in diameter) has been used to pass the obstruction. It is possible to have a direct vision of the anatomy and pathology, and to pass the guidewire above the obstruction, through the nasogastroscope, under direct vision. Fluoroscopy was also used to follow the course of the guidewire and deployment of the stent. RESULTS: Early and late complications have been reduced with the new technique. CONCLUSIONS: In the most recent experience of 64 patients, early and late complications have been reduced significantly. This new technique reduces radiation exposure by 70% for the patients and for the operators. PMID- 30300254 TI - Is Prophylactic Steroid Treatment Mandatory for Subclinical Cushing Syndrome After Unilateral Laparoscopic Adrenalectomy? AB - OBJECTIVE: This study aimed to provide rational guidelines for patients with subclinical Cushing syndrome (SCS), who are undergoing laparoscopic adrenalectomy, in order to avoid the risk of overtreatment. METHODS: A total of 59 patients diagnosed with SCS caused by unilateral adrenal adenoma, who underwent laparoscopic adrenalectomy from 2010 to 2017, were included into the study. These patients did not receive prophylactic steroid treatment. After discharge, patients with adrenal insufficiency (AI) were treated with glucocorticoid. Then, cortisol levels were reevaluated at three months after surgery by morning serum cortisol. RESULTS: No severe perioperative complications occurred. After unilateral laparoscopic adrenalectomy, no patient developed AI and was readmitted. In the first week after surgery, 10 patients (16.9%) received steroid therapy at the clinic because of mild symptoms of AI. The probability of developing AI was greater in patients with 1-mg dexamethasone midnight suppression test (1 mg-DST) >5 MUg/dL than patients with mg-DST ranging within 1.8 to 5.0 MUg/dL (P=0.042). The initial dose of hydrocortisone was 20.00+/-6.67 mg/d (range, 10 to 30), and the duration of treatment was 6.90+/-3.51 weeks (range, 3 to 12 wk). At three months after surgery, morning cortisol was >5 MUg/dL in all patients. CONCLUSIONS: After laparoscopic adrenalectomy, the probability of AI is small in patients with adrenal SCS, and the symptoms of AI were mild. Meanwhile, the HPA axis rapidly recovered. Therefore, prophylactic steroid treatment is not mandatory. Given that AI is more frequent in patients with higher cut-offs of 1 mg-DST, a more precise definition of SCS is necessary to better manage these patients. PMID- 30300255 TI - Complete Jejunal Transection After Blunt Abdominal Trauma: A Case Report. AB - INTRODUCTION: Isolated complete transection of the small bowel is extremely rare in blunt abdominal trauma. If it occurs, it is often associated with high-energy impact, as seen in motor vehicle accidents and falls from heights. In this case, a trivial trauma due to a handlebar injury caused a complete transection of the middle jejunum. CASE PRESENTATION: A 47-year-old man walked into the emergency department with moderate abdominal pain ~10 hours after a fall on to a bicycle's handlebar from a standing position. A bedside ultrasound showed minimal amount of free fluid and a following performed computed tomographic scan indicated an edematous loop of small bowel with diminutive amount of extraluminal air, suggesting small bowel perforation. Because of the absence of abdominal peritonism in a hemodynamically stable patient, a conservative treatment and surveillance was established. In the follow-up, the patient suddenly developed severe abdominal pain with now clear signs of peritonism. An emergency laparoscopy showed a complete transection of the middle jejunum. A primary anastomosis was performed. The patient had an uneventful recovery and was discharged after 7 days. CONCLUSIONS: Even seemingly trivial blunt abdominal traumas can cause complete transection of the small bowel, as shown in this case. Patients with blunt abdominal trauma need to be reviewed frequently by an experienced clinician. Diagnostic laparoscopy attaches a great importance to early detection and treatment of small bowel injuries. The mechanical pattern of the injury seems to be more important than the energy of the impact itself. PMID- 30300256 TI - Obstructive Sleep Apnea in Neuro-Ophthalmology. AB - BACKGROUND: Obstructive sleep apnea (OSA) is a common pulmonary disorder with many systemic sequelae. Its association with diseases seen in neuro-ophthalmology is being increasingly recognized. Treatment of OSA with continuous positive airway pressure (CPAP) may reverse the pathology in some eye diseases. EVIDENCE ACQUISITION: We conducted a search of the literature using the Ovid Medline database and Google Scholar, focusing on articles that explored the association between OSA and ophthalmic conditions. These included hypertensive retinopathy, diabetic retinopathy, central serous retinopathy (CSR), retinal vein occlusion (RVO), nonarteritic anterior ischemic optic neuropathy (NAION), glaucoma, idiopathic intracranial hypertension (IIH), papilledema, and stroke. RESULTS: There is evidence of an independent association between OSA, and both hypertension and Type 2 diabetes mellitus, as well as the retinopathy associated with each disease. Evidence also suggests a link between OSA and CSR, NAION, and stroke. The evidence remains controversial or insufficient for convincing causative association with RVO, glaucoma, and IIH. However, in patients presenting with CSR, and IIH, underlying OSA is a common finding. CPAP reverses some pathological changes, but the evidence is limited. CONCLUSIONS: OSA is associated with many diseases seen in neuro-ophthalmology clinics. More studies are required to assess the real ability of CPAP to reverse pathological changes. Ophthalmologists can screen for undiagnosed OSA in patients presenting with certain eye diseases. PMID- 30300257 TI - Risk Factors for Fellow Eye Involvement in Nonarteritic Anterior Ischemic Optic Neuropathy. AB - BACKGROUND: Nonarteritic anterior ischemic optic neuropathy (NAION) is the most common acute optic neuropathy in individuals older than 50 years. Demographic, ocular, and systemic risk factors for NAION have been identified, and we sought to determine which, if any, of these factors also increase risk of NAION in the fellow eye. METHODS: We performed a retrospective chart review of patients with "ischemic optic neuropathy" (based on International Classification of Disease [ICD] codes) seen at a single eye center between 2007 and 2017. Patients who met diagnostic criteria for unilateral NAION without fellow eye optic neuropathy at diagnosis were included. Demographic information, ocular comorbidities, and systemic diagnoses were recorded, in addition to whether the fellow eye developed NAION during the follow-up period. Univariate and multivariate Cox proportional hazard regression were used to calculate hazard ratios (HRs) for fellow eye involvement. RESULTS: Three hundred eighteen patients were identified by ICD codes, and 119 were included in the study. Twenty-nine (24%) patients developed NAION in the fellow eye over the mean follow-up period of 3.6 years (range: 1 month-11 years). Significant risk factors for fellow eye NAION included the presence of bilateral optic disc drusen (ODD, HR 2.78, 95% confidence interval [CI] 1.12-6.90, P = 0.02) and noncompliance with continuous positive airway pressure (CPAP) in patients with moderate-to-severe obstructive sleep apnea (HR 4.50, 95% CI 1.79-11.3, P = 0.0015). CONCLUSIONS: Bilateral ODD and noncompliance with CPAP when indicated are associated with increased risk of NAION in the fellow eye. Patients with these risk factors should be counseled on the potentially devastating visual consequences of bilateral NAION, and compliance with CPAP should be stressed when appropriate. PMID- 30300258 TI - Experience with definitive instrumented final fusion after posterior-based distraction lengthening in patients with early-onset spinal deformity: single center results. AB - Limited reports exist with regard to clinical and radiographic details of patients with early-onset spinal deformity (EOSD) undergoing definitive instrumented final fusion (FF) following implantation of a growing construct. Charts and radiographs were queried for all patients who underwent FF after management of EOSD with a distraction-based posterior construct at a single institution from 2006 to 2017. Patients managed during the growth modulation period with either proximal rib or spinal fixation were included. Thirteen patients qualified for inclusion. Spinal deformity etiologies were varied (neuromuscular: 5, idiopathic: 4, congenital: 4). Average age at implantation was 6.5 years, and patients underwent an average of 8.15 lengthening procedures over an average of 69 months. After the growing program, modest correction in main coronal Cobb was obtained at FF (average 52.4 degrees before FF, 37.6 degrees following FF, P<0.001; average percent improvement of 27%). Five patients required posterior column osteotomies. Using criteria proposed by Flynn and colleagues, 'minimal' coronal correction was achieved in 23% of patients and 'moderate' in 77%. No patient achieved 'substantial' (>50%) correction. Subjective poor bone quality was appreciated in 67% of patients, and 85% were noted to have areas of autofusion over previously spanned levels. Two (15%) patients sustained a total of four complications. After growth modulation procedures, EOSD deformities are generally stiff, bone quality is often subjectively poor, and autofusion is common, even after use of proximally rib based systems. Modestly improved coronal Cobb correction can be obtained at FF but may require single or multiple posterior osteotomies. Intraoperative difficulties can be expected, and clinicians should be alert for intraoperative and postoperative complications. PMID- 30300259 TI - XXXI. Julius Schottlaender. PMID- 30300261 TI - Foreword. PMID- 30300262 TI - Vitamin D: Immunomodulatory Aspects. AB - Vitamin D is a group of liposoluble prohormones consisting of 5 different vitamins, the most important forms being vitamin D2 and vitamin D3. The ergocalciferol (vitamin D2) is less efficacious and derives from irradiated fungi, while colecalciferol (vitamin D3), derived from cholesterol, is synthesized via ultraviolet B rays in animal organisms. Only the ultraviolet B rays (290 to 315 nm) portion of the solar ray photolyzes 7-dehydrocholesterol in the skin to previtamin D3, which is converted subsequently to vitamin D3. Moreover, the skin makes little vitamin D from the sun at latitudes above 37 degrees north or below 37 degrees south of the equator. Calcidiol [25(OH)D] is the more stable metabolite of vitamin D in serum and the best indicator of the vitamin D status. Optimal values range are >30 ng/mL. Calcitriol [1,25(OH)2D] is the active hormone form of vitamin D. The 1,25(OH)2D binds to its nuclear receptor (vitamin D receptor), expressed in many tissues, regulating the expression of genes involved in calcium metabolism, cell differentiation, apoptosis, and immunity. About immunity, calcitriol stimulates innate immune responses by enhancing the chemotactic and phagocytotic responses of macrophages as well as the production of antimicrobial peptides. 1,25(OH)2D strongly enhances production of interleukine-10 by stimulating T regulatory cells and inhibiting Th1 and Th17 cell differentiation. Furthermore, several studies suggest that lower 25(OH)D serum levels are associated with an increased risk of respiratory infection at all ages in a dose-response manner. PMID- 30300260 TI - Treatment With Tumor-infiltrating Lymphocytes in Advanced Melanoma: Evaluation of Early Clinical Implementation of an Advanced Therapy Medicinal Product. AB - Tumor-infiltrating lymphocytes (TIL)-therapy in advanced melanoma is an advanced therapy medicinal product (ATMP) which, despite promising results, has not been implemented widely. In a European setting, TIL-therapy has been in use since 2011 and is currently being evaluated in a randomized controlled trial. As clinical implementation of ATMPs is challenging, this study aims to evaluate early application of TIL-therapy, through the application of a constructive technology assessment (CTA). First the literature on ATMP barriers and facilitators in clinical translation was summarized. Subsequently, application of TIL-therapy was evaluated through semistructured interviews with 26 stakeholders according to 6 CTA domains: clinical, economic, patient-related, organizational, technical, and future. In addition, treatment costs were estimated. A number of barriers to clinical translation were identified in the literature, including: inadequate financial support, lack of regulatory knowledge, risks in using live tissues, and the complex path to market approval. Innovative reimbursement procedures could particularly facilitate translation. The CTA survey of TIL-therapy acknowledged these barriers, and revealed the following facilitators: the expected effectiveness resulting in institutional support for an internal pilot, the results of which led to the inclusion of TIL-therapy in a national coverage with evidence development program, the availability of an in-house pharmacist, quality assurance expertise and a TIL-skilled technician. Institutional and national implementation of TIL-therapy remains complex. The promising clinical effectiveness is expected to facilitate the adoption of TIL-therapy, especially when validated through a randomized controlled trial. Innovative and conditional reimbursement procedures, together with the organization of knowledge transfer, could support and improve clinical translation of TIL and ATMPs. PMID- 30300263 TI - ULTRASOUND IN VITRECTOMY: An Alternative Approach to Traditional Vitrectomy Techniques. AB - PURPOSE: To study a prototype of an ultrasound-based vitrector, and to try to understand the physical phenomena underlying this new technology. METHODS: We tested the ultrasound-based vitrector prototype (UV) (ultrasonically-driven handpiece obtained from a modified version of the Alcon CONSTELLATION Vision System [Alcon]) using an automatic experimental setup. Balanced saline solution (BSS) and vitreous (from fresh postmortem enucleated porcine eyes) flow rates were analyzed using three different tips. RESULTS: In general, BSS solution flow rates increased with increasing aspiration levels and decreased when we used % US power. Vitreous flow rates were influenced by aspiration levels, % US power, and ultrasound-related phenomena: cavitation phenomenon and "jet streaming." CONCLUSION: Ultrasound-based vitrectomy may represent an important alternative to traditional vitrectomy. Such a tool, capable of liquefying and excising the vitreous body using ultrasound, could overcome all the limits of the guillotine based technique (GV). Knowledge of the physical phenomena underlying ultrasound based technology is a necessary prerequisite for further development of this new technology. PMID- 30300264 TI - MESOPIC AND DARK-ADAPTED TWO-COLOR FUNDUS-CONTROLLED PERIMETRY IN GEOGRAPHIC ATROPHY SECONDARY TO AGE-RELATED MACULAR DEGENERATION. AB - PURPOSE: To investigate retinal sensitivity in the junctional zone of geographic atrophy (GA) secondary to age-related macular degeneration using patient-tailored perimetry grids for mesopic and dark-adapted two-color fundus-controlled perimetry. METHODS: Twenty-five eyes with GA of 25 patients (prospective, natural history Directional Spread in Geographic Atrophy study [DSGA; NCT02051998]) and 40 eyes of 40 normal subjects were included. Patient-tailored perimetry grids were generated using annotated fundus autofluorescence data. Customized software positioned test-points along iso-hulls surrounding the GA boundary at distances of 0.43 degrees , 0.86 degrees , 1.29 degrees , 2.15 degrees , and 3.01 degrees . The grids were used for duplicate mesopic and dark-adapted two-color (cyan and red) fundus-controlled perimetry. Age-adjusted reference-data were obtained through regression analysis of normative data followed by spatial interpolation. RESULTS: The mean sensitivity loss for mesopic testing decreased with the distance to GA (-10.3 dB [0.43 degrees ], -8.2 dB [0.86 degrees ], -7.1 dB [1.29 degrees ], -6.8 dB [2.15 degrees ], and -6.6 dB [3.01 degrees ]; P < 0.01). Dark adapted cyan sensitivity loss exceeded dark-adapted red sensitivity loss for all iso-hulls (-14.8 vs. -11.7 dB, -13.5 vs. -10.1 dB, -12.8 vs. -9.1 dB, -11.6 vs. 8.2 dB, -10.7 vs. -8.0 dB; P < 0.01). CONCLUSION: Patient-tailored fundus controlled perimetry grids allowed for testing of retinal function in the junctional zone of GA with high spatial resolution. A distinct decrease in mesopic sensitivity loss between 0.43 degrees (125 um) and 1.29 degrees (375 um) was observed that leveled off at more distant test-points. In proximity to the GA boundary, the results indicate that rod exceeded cone dysfunction. PMID- 30300265 TI - COMPARISON BETWEEN RELEASABLE SCLERAL BUCKLING AND VITRECTOMY IN PATIENTS WITH PHAKIC PRIMARY RHEGMATOGENOUS RETINAL DETACHMENT. AB - PURPOSE: To compare the efficiency of releasable scleral buckling (RSB) and pars plana vitrectomy (PPV) in the treatment of phakic patients with primary rhegmatogenous retinal detachment. METHODS: The current study was a prospective randomized clinical trial. One hundred and ten eyes from 110 patients with primary rhegmatogenous retinal detachment and proliferative vitreoretinopathy of Grade B or less were included in this study. The patients were randomly allocated into an RSB group and a PPV group. The functional and anatomical success was compared between groups. RESULTS: The primary anatomical success rate (PPV 41/43 [95.35%] and RSB 38/41 [92.68%]) and final anatomical success rate (PPV and RSB 100%) showed a nonsignificant difference. The best-corrected visual acuity, intraocular pressure, and complications were not different between the groups. However, the incidence of cataract progression was higher in the PPV group (26 of 43 [60.47%]) than in the RSB group (4 of 41 [9.76%]) at the 12-month follow-up. The subfoveal choroidal thickness increased significantly in the RSB group 3 months after surgery, but no longer differed at the postoperative 6-month and 12 month follow-ups. The axial length had increased significantly 1 month after surgery, but the difference was no longer significant at 3 months, 6 months, and 12 months. CONCLUSION: The RSB and PPV procedures have the same effects on the functional and anatomical success for patients with phakic primary rhegmatogenous retinal detachment. Nevertheless, based on the few cases of intraocular complications and cataract progression, we believe that the RSB technique should be preferentially recommended.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30300266 TI - RELATIONSHIP BETWEEN STAGES OF DIABETIC RETINOPATHY AND LEVELS OF BRAIN-DERIVED NEUROTROPHIC FACTOR IN AQUEOUS HUMOR AND SERUM. AB - PURPOSE: The aim of the study was to determine aqueous humor and serum levels of brain-derived neurotrophic factor (BDNF) in diabetic patients with and without retinopathy. METHODS: The study included diabetic patients with or without retinopathy, who had an indication for cataract surgery. The study groups were diabetic patients without retinopathy (Group 2), with nonproliferative diabetic retinopathy (Group 3), and with proliferative retinopathy (Group 4). To quantitatively determine the amount of BDNF in samples, the RayBio Human BDNF ELISA kit (Norcross, GA), based on an enzyme-labeled immunosorbent assay was used. RESULTS: The median serum BDNF levels were significantly lower in all the study groups than in the control group (P values: 0.038 Group 2, 0.02 Group 3, and 0.002 Group 4). Serum BDNF was lower in Group 4 than in Group 3 (P = 0.030), and in Group 3 than in Group 2 (P = 0.04). The median aqueous humor BDNF levels were significantly decreased in all groups (P values: 0.047 Group 2, 0.021 Group 3, and 0.007 Group 4). There was no significant difference between Groups 2, 3, and 4 (P = 0.214). CONCLUSION: The serum and aqueous humor BDNF levels decreased in patients with diabetes mellitus (DM) before the emergence of clinical signs of retinopathy. PMID- 30300267 TI - CHANGES OF AQUEOUS HUMOR MULLER CELLS' BIOMARKERS IN HUMAN PATIENTS AFFECTED BY DIABETIC MACULAR EDEMA AFTER SUBTHRESHOLD MICROPULSE LASER TREATMENT. AB - PURPOSE: To evaluate the changes in activity of biomarkers of Mu[Combining Diaeresis]ller cells (MC) in aqueous humor of patients with diabetic macular edema after subthreshold micropulse laser, over 1 year. METHODS: Patients with untreated diabetic macular edema and central retinal thickness <= 400 MUm were enrolled. Best-corrected visual acuity, full ophthalmic examination, and optical coherence tomography were performed. Subthreshold micropulse laser was applied every 3 months. Glial fibrillary acidic protein and inwardly rectifying potassium channel (Kir 4.1), MC activity markers, and vascular endothelial growth factor were quantified in the aqueous humor collected at baseline and at 1, 3, and 12 months after laser. Changes in the macular thickness and inner nuclear layer thickness, where MC bodies are located, were measured. RESULTS: Ten eyes of 10 patients were included. Best-corrected visual acuity improved at 3 months (P = 0.047) and remained stable. Inner nuclear layer thickness significantly reduced at 12 months (P = 0.012). Glial fibrillary acidic protein, Kir 4.1, and vascular endothelial growth factor decreased at 1 and/or 3 and/or 12 months compared with baseline (P < 0.05). CONCLUSION: Subthreshold micropulse laser improves visual function in diabetic macular edema. Kir 4.1 and glial fibrillary acidic protein decrease and inner nuclear layer thickness reduction demonstrate that subthreshold micropulse laser may restore MC function. Subthreshold micropulse laser also reduces vascular endothelial growth factor concentration. The effect of subthreshold micropulse laser in diabetic macular edema may in part be due to changes of MC metabolic activity. PMID- 30300268 TI - OUTCOME OF ACUTE NONTRAUMATIC VITREOUS HEMORRHAGE IN HEALTHY PATIENTS. AB - PURPOSE: To compare outcomes in dense vitreous hemorrhage versus mild vitreous hemorrhage due to nontraumatic posterior vitreous detachment. METHODS: We compared 315 eyes, divided into 2 patient groups, one with dense and the other with mild vitreous hemorrhage. The main outcome measures were final mean best corrected visual acuity, number of retinal tears, number of retinal detachments, and the number of pars plana vitrectomy and/or scleral buckle surgeries. RESULTS: In 33.4% of the patients, posterior vitreous detachment without complications was found. Retinal breaks after posterior vitreous detachment were found in 59% of the eyes. Rhegmatogenous retinal detachment was principally treated with pars plana vitrectomy and scleral buckle. In nonvisible fundus hemorrhage group, 44.4% of the patients underwent vitrectomy. In visible fundus hemorrhage group, 9.52% of the patients underwent pars plana vitrectomy. The mean final visual acuity was 20/25, without significant difference between groups (P = 0.064). CONCLUSION: Acute, spontaneous, nontraumatic posterior vitreous separation with vitreous hemorrhage is associated with a high incidence of retinal complications. Close follow-up is necessary. We did not find significant differences in final visual acuity neither between the two groups nor among the treatments. PMID- 30300269 TI - GENETIC RISK FACTORS IN ACUTE CENTRAL SEROUS CHORIORETINOPATHY. AB - PURPOSE: To investigate genetic associations in white patients with acute central serous chorioretinopathy (aCSC) and to assess genetic differences between aCSC and chronic CSC (cCSC). METHODS: A total of 135 aCSC patients, 272 cCSC patients, and 1,385 control individuals were included. Eight single nucleotide polymorphisms were genotyped for ARMS2 (rs10490924), CFH (rs800292, rs1061170, rs1065489, rs1329428, rs2284664, rs3753394), and NR3C2 (rs2070951). Also, C4B gene copy numbers were analyzed. RESULTS: Three single nucleotide polymorphisms in the CFH gene were significantly associated with aCSC: rs800292 (P = 0.003, odds ratio = 1.53 [95% confidence interval = 1.15-2.03]), rs1061170 (P = 0.002, odds ratio = 0.64 [95% confidence interval = 0.48-0.86]), and rs1329428 (P = 5.87 * 10, odds ratio = 1.83 [95% confidence interval = 1.40-2.38]). A significant difference was found in the distribution of C4B gene copy numbers in aCSC patients compared with controls (P = 0.0042). No differences could be found among the selected variants between aCSC and cCSC patients. CONCLUSION: Three variants in the CFH gene and copy number variations in C4B were found to be significantly associated with the risk of aCSC development. Despite the differences in clinical presentation, acute and chronic CSC may share a similar genetic predisposition based on our present analysis. Other genetic and/or nongenetic risk factors may be more influential in the differentiation toward an acute or a chronic phenotype of CSC. PMID- 30300270 TI - Correspondence.

PMID- 30300273 TI - Combined Reconstruction of the Medial Patellofemoral Ligament (MPFL) and Medial Quadriceps Tendon-Femoral Ligament (MQTFL) for Patellar Instability in Children and Adolescents: Surgical Technique and Outcomes. AB - OBJECTIVES: A variety of surgical options exist to treat the challenging problem of recurrent patellar instability in children and adolescents. The goal of the current study is to describe a novel combined reconstruction technique of both the medial patellofemoral ligament (MPFL) and the medial quadriceps tendon femoral ligament (MQTFL) and report patient outcomes of a single-surgeon series. METHODS: All patients studied underwent simultaneous MPFL and MQTFL reconstruction for patellar instability using gracilis allograft. Demographic, clinical, and radiographic data were collected. Subjective outcomes were assessed for a minimum of 1 year postoperatively. RESULTS: Twenty-five patients (27 knees), including 15 female and 10 male individuals with an average age of 15.0+/ 2.2 years (range, 10.3 to 18.9), were included. Prior ipsilateral patellofemoral surgery had been performed in 6 of 25 (24%) patients. Simultaneous hemiepiphysiodesis for valgus deformity at the time of combined reconstruction was performed in 5 of 25 (20%) patients. Preoperative imaging showed a mean tibial tubercle-trochlear groove of 17.2+/-3.8, Caton-Deschamps Index (CDI) of 1.13+/-0.16, and trochlear dysplasia Dejour A/B [22/26 (85%)] or Dejour C/D [4/26 (15%)]. A total of 18 patients (19 knees, 72%) returned outcomes questionnaires at a mean 2.0+/-0.5 years after surgery. Mean Kujala, Pedi-IKDC, and Lysholm scores were 85.9+/-13.9, 81.5+/-15.2, and 84.3+/-13.5, respectively. Later revision procedure (tibial tubercle osteotomy) for recurrent patellar instability was required in 2 of 25 patients (8%) patients, and another patient reported persistent instability not requiring revision. Return to sports was possible in 10 of 13 self-reported athletes (77%) at a mean of 5.8+/-3.9 months (range, 2 to 15). CONCLUSIONS: The present study describes a combined MPFL-MQTFL reconstruction technique with favorable short-term results. Although particularly useful in the skeletally immature patient where tibial tubercle osteotomy should be avoided and patellar fixation minimized, combined reconstruction may potentially be appropriate for older patients with patellofemoral instability as well. This technique more closely recreates the native anatomy of both the MPFL and MQTFL, may decrease the risk of patellar fracture, and can be useful in the revision setting. LEVEL OF EVIDENCE: Level IV. PMID- 30300274 TI - Persistence and Progression of Airway Obstruction in Children With Early Onset Scoliosis. AB - BACKGROUND: Obstructive lung disease occurs in 30% of children with early onset scoliosis (EOS); changes in degree of airway obstruction over time have not been reported. METHODS: Longitudinal patterns of incidental, persistent, and progressive airway obstruction were retrospectively analyzed in a cohort of children with EOS with at least 1 forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) value <85% on serial spirometric assessments over a >=3-year observation period. The prevalence of clinical features and the severity of coronal and sagittal spine deformities for each group at the beginning and end of the study period were compared. RESULTS: Airway obstruction was incidental in 12 (24%) and persistent in 37 (76%) of 49 children with EOS. Twenty of 37 (54%) of those with persistent obstruction developed progressive airway obstruction. The decline in FEV1/FVC over 6+/-2 years was insignificant in the incidental group (4%+/-2%) and the persistent nonprogressive group (7%+/-4%) but significant in the progressive group (13%+/-4%, t test; P=0.002). In total, 29% of the 49 children at the onset and 57% at the end of the study had airway obstruction. The incidental, persistent nonprogressive, and progressive groups did not differ with regard to age, diagnosis distribution, or sex. The initial coronal curve size, apex, direction of the curve, and degree of kyphosis were statistically similar among the 3 groups. Coronal curve magnitude inversely correlated with FEV1/FVC at the end but not the beginning of the study (r=-0.19, P=0.002). Six of 19 responded to bronchodilator treatment, suggesting concurrent asthma. Airway obstruction did not relate to restrictive pulmonary abnormalities measured by FVC at first or last timepoints [slope=-0.076 (95% confidence interval, -0.99 to 0.038; P=0.19)]. Changes in degrees of airway obstruction and restrictive lung disease over time did not correlate [slope=-0.125 (95% confidence interval, -0.294 to 0.044; P=0.14)]. CONCLUSIONS: Children with EOS and progressive airway obstruction represent an important subgroup which may require new surgical and nonsurgical treatment strategies to prevent loss of lung function over time. PMID- 30300276 TI - Hip Status and Long-term Functional Outcomes in Spina Bifida. AB - BACKGROUND: Nearly 50% of individuals with myelomeningocele will develop a dislocated hip by skeletal maturity. The purpose of this study was to determine the influence of hip status on functional outcomes in a cohort of adult patients with myelomeningocele. METHODS: Patients with a diagnosis of myelomeningocele >18 years were prospectively enrolled over a 12-month period. Neurological level of involvement was obtained from chart review and interview. Clinical examination included hip range of motion and leg-length discrepancy. Reimer's migration index was calculated from a current anteroposterior pelvic radiograph. All subjects completed the VR-12 and the NIH PROMIS outcomes measures for pain interference and physical function. The chi, the Pearson correlation coefficients, and linear regression models were applied to evaluate the influence of hip status on functional outcomes. RESULTS: In total, 31 patients (average age 31, range 19 to 49) were included. Eight thoracic, 9 lumbar, and 14 sacral level patients participated. Twenty had bilaterally located hips, 5 had a unilateral subluxation or dislocation, and 6 had bilaterally subluxated or dislocated hips. In univariate analysis, patients with bilaterally located hips performed better in lower extremity function than those with unilateral subluxation/dislocation (36.7 vs. 26.0; P=0.03) but worse in pain interference than those with bilateral subluxation/dislocation (52.0 vs. 43.3; P=0.03). After controlling for neurological level, there was no statistically significant difference in the VR 12 mental (P=0.32) or physical component summary (P=0.32) scores, nor in the PROMIS lower extremity function (P=0.26) or pain interference scores (P=0.33) between groups. Decreased extension and abduction were indirectly correlated with VR-12 mental component scores (P=0.0038, 0.0032). Leg-length discrepancy was not associated with any outcome measure. CONCLUSIONS: Long-term outcomes are not associated with hip status in adult patients with myelomeningocele. Functional outcomes are more closely correlated with neurological level and hip range of motion. These results suggest efforts to keep myelomeningocele hips reduced are likely without functional benefit and should be avoided in favor of maintaining motion with contracture release as needed.

AB - BACKGROUND: The rate of venous thromboembolism in children with musculoskeletal infections (MSKIs) is markedly elevated compared with hospitalized children in general. Predictive biomarkers to identify high-risk patients are needed to prevent the significant morbidity and rare mortality associated with thrombotic complications. We hypothesize that overactivation of the acute phase response is associated with the development of pathologic thrombi and we aim to determine whether elevations in C-reactive protein (CRP) are associated with increased rates of thrombosis in pediatric patients with MSKI. METHODS: A retrospective cohort study measuring CRP in pediatric MSKI patients with or without thrombotic complications. RESULTS: The magnitude and duration of elevation in CRP values correlated with the severity of infection and the development of pathologic thrombosis. In multivariable logistic regression, every 20 mg/L increase in peak CRP was associated with a 29% increased risk of thrombosis (P<0.001). Peak and total CRP were strong predictors of thrombosis with area under the receiver operator curves of 0.90 and 0.92, respectively. CONCLUSIONS: Future prospective studies are warranted to further define the discriminatory power of CRP in predicting infection-provoked thrombosis. Pharmacologic prophylaxis and increased surveillance should be strongly considered in patients with MSKI, particularly those with disseminated disease and marked elevation of CRP.

AB - PURPOSE: Clinical changes are best evaluated with standardized, validated outcomes, including both patient-reported outcome measures and surgeon-reported outcome measures (PROMs and SROMs). The purpose of this study was to describe the spectrum of outcome measures used in pediatric orthopaedic publications over the past 10 years and to determine the proportion that are in fact age-appropriate, validated, and appropriately applied in terms of condition and population. METHODS: The Journal of Bone and Joint Surgery, The Bone and Joint Journal, Journal of Pediatric Orthopaedics A and B, and Journal of Children's Orthopaedics were systematically searched for studies including children aged 18 and below, over a 10-year period from January 2005 to December 2014. Economic evaluations, letters, editorials, review articles, and clinical guidelines were excluded. SROMs and PROMs used were extracted, as were details on subject age and condition for which they were used. Each outcome scale was assessed for validity, and the proportion of scales used appropriately was calculated. Cochrane-Armitage test of trend was used to determine changes in PROM and SROM utilization over the study period. RESULTS: A total of 4614 articles were identified, of which 2251 met inclusion and exclusion criteria. In total, 259 (11.5%) of studies used a PROM, whereas 326 (14.5%) used a SROM. A total of 230 different outcome scales were identified; 115 were patient reported and 115 were surgeon reported. However, only 18.7% of SROMs and 38.3% of PROMs were applied to an age and disease appropriate demographic. Overall, there was a significant increase in the overall utilization of PROMs during the study period (P=0.004), but no corresponding increase in pediatric-validated PROMs (P=0.164). SROM utilization did not significantly change over the study period (P=0.337). CONCLUSIONS: Within the field of pediatric orthopaedics, an expansive variety of outcome scales are used, many of which have not been validated in children. Improved uniformity in reporting of outcomes and use of disease and age-validated outcomes scales is essential to improve multicenter research collaboration and data quality to generate appropriate evidence-based conclusions and treatment strategies in pediatric orthopaedics. LEVEL OF EVIDENCE: Level IV-systematic review. PMID- 30300278 TI - Comparison of 3 Pediatric Pelvic Osteotomies for Acetabular Dysplasia Using Patient-specific 3D-printed Models. AB - BACKGROUND: Children with developmental dysplasia of the hip may require a pelvic osteotomy to treat acetabular dysplasia. Three osteotomies are commonly performed in these patients (Pemberton, Dega, and San Diego), though comparative studies of each are limited. The purpose of this study was to compare changes in acetabular morphology (acetabular version, volume, and octant coverage angles) created by these 3 osteotomies using matched patient-specific 3D-printed pelvic models. METHODS: Fourteen patients with developmental dysplasia of the hip and preoperative computed tomography (CT) imaging were retrospectively included. For each patient CT, bone and cartilage tissues were independently segmented, and 3 identical pelvises were 3D-printed using a dual material printer. Bone was printed with rigid material and cartilage with flexible material to simulate the flexibility of the triradiate cartilage and pubic symphysis. Pemberton, Dega, and San Diego acetabular osteotomies were performed on the triplicate set of 3D prints. Acetabular version, volume, and octant coverage angles (posterior, superior-posterior, superior, superior-anterior, and anterior) were determined before and after each mock surgery by morphologic assessment using preoperative and postoperative CT images. RESULTS: San Diego osteotomy yielded a small increase (+3.34+/-1.71 degrees) in version, compared with decreases with Pemberton (-5.47+/-1.54 degrees) and Dega (-8.57+/-1.21 degrees, P<0.05). Acetabular volume decreased similarly for Pemberton (-13.36%+/-2.88%), Dega ( 19.21%+/-2.73%), and San Diego (-19.29%+/-2.44%; P=0.215) osteotomies. San Diego osteotomy tended to have a larger postoperative increase in the posterior regions, and the Dega and Pemberton osteotomies tended to have larger postoperative increases in the anterior coverage regions. CONCLUSIONS: Quantifiable differences were identified in acetabular octant coverage angles and version between the 3 pelvic osteotomies. San Diego osteotomy increased acetabular coverage posteriorly resulting in acetabular anteversion, whereas Pemberton and Dega had greater superior-anterior coverage resulting in relative acetabular retroversion. This study is the first known to utilize 3D-printed models for comparison of surgical approaches in pediatric pelvic osteotomies. PMID- 30300279 TI - Biomechanical Assessment of Torsional Stiffness in a Supracondylar Humerus Fracture Model. AB - BACKGROUND: We assessed the effect on the torsional stability by different pin diameters and varied pin configurations in a biomechanical supracondylar humerus fracture model. METHODS: After scanning a model of a pediatric humerus, the image was imported into software. Variable pin trajectories were planned. Acrylonitrile butadiene styrene plastic models were 3-dimensionally printed with predetermined pin trajectories. Models were osteotomized and potted with a polyurethane resin. Five-pin configurations were designed to test coronal and sagittal patterns of pin placement. Each included 3 lateral pins and a medial pin. Pin diameters of 1.6, 2.0, and 2.4 mm were tested in all configurations. Three models for each pin diameter/configuration were tested to ensure uniformity. Stability of the construct was tested to determine the torque needed to deflect the osteotomy 10 degrees in internal/external rotation. Each model was tested 3 times. RESULTS: In all models/configurations, the 2.4 mm pin diameter was statistically stiffer than 1.6 mm diameter pins; this lost statistical significance in certain patterns when comparing 2.0- and 2.4-mm pins. When comparing a divergent to a parallel configuration in the coronal plane, there was no significant difference in stability when pin diameter or number were controlled. The convergent pin configuration was, in general, the least stable pattern. Use of a medial pin conferred statistically significant stiffness throughout most models as demonstrated with pin deletion. Use of 2 pins was significantly less stiff than most 3-pin models. CONCLUSIONS: Larger pin diameters confer greater stiffness among all patterns. The use of 3 lateral and 1 medial pin was not statistically different than 2 lateral and 1 medial pin in our models. Both patterns were stiffer than 3 lateral pins only or other fewer pin constructs. The alignment of pins in the sagittal plane did not affect overall construct stiffness. PMID- 30300280 TI - Emerging Ethical Challenges Raised by the Evolution of Vascularized Composite Allotransplantation. AB - BACKGROUND: Despite early skepticism, the field of vascularized composite allotransplantation (VCA) has demonstrated feasibility. The ethics of VCA have moved past doubts about the morality of attempting such transplant to how to conduct them ethically. METHODS: Leaders of each program performing and/or evaluating VCA in the United States were invited to participate in a working group to assess the state and future of VCA ethics and policy. Four meetings were held over the course of 1 year to describe key challenges and potential solutions. RESULTS: Working group participants concluded that VCA holds great promise as treatment for patients with particular injuries or deficits, but the field faces unique challenges to adoption as standard of care, which can only be overcome by data sharing and standardization of evaluation and outcome metrics. CONCLUSIONS: Adequate attention must be given to concerns including managing the uniquely intense physician-patient relationship, ethical patient selection, ensuring patients have adequate representation, informing and earning the trust of the public for donation, standardizing metrics for success, and fostering an environment of data sharing. These steps are critical to transitioning VCA from research to standard of care, and to its insurance coverage inclusion.

PMID- 30300282 TI - Urinary TIMP-2 predicts the presence and duration of delayed graft function in donation after circulatory death kidney transplant recipients. AB - BACKGROUND: Urinary tissue inhibitor of metalloproteinases-2 (TIMP-2) and insulin like growth factor binding protein-7 (IGFBP7) have been validated as biomarkers for acute kidney injury. We investigated the performance of both markers in predicting the occurrence and duration of functionally defined delayed graft function (fDGF) in donation after circulatory death (DCD) kidney transplant recipients. METHODS: Urine samples of 74 DCD recipients were analyzed. TIMP-2 and IGFBP7 were measured with ELISA on postoperative day 1 to 7, day 10, week 6 and month 6 and values were corrected for osmolality (mOsm). Immunosuppression consisted of anti-CD25 antibody induction and triple maintenance therapy (steroids, MMF and CNI). Statistical analysis included receiver operating characteristic curves and multivariate logistic regression. RESULTS: Fifty-one renal transplant recipients had fDGF (69%), of which 14 experienced prolonged fDGF (>=21 days). TIMP-2/mOsm on day-1 and day-10 adequately identified patients with fDGF (AUC 0.91) and prolonged fDGF (AUC 0.80), respectively, whereas IGFBP7/mOsm did not (AUC 0.63 and 0.60). Multivariate analysis on day-1 identified 24-hour urinary creatinine excretion and TIMP-2/mOsm as significant predictors of fDGF (AUC 0.90, 95% CI 0.80-0.98). The best predictors of prolonged fDGF on day-10 were 24-hour urinary creatinine excretion, TIMP-2/mOsm and total warm ischemia time with an AUC of 0.85 (95% CI: 0.72-0.95). Consecutive TIMP 2/mOsm values showed a decrease in TIMP-2/mOsm prior to an increase in eGFR, enabling us to monitor fDGF and predict resolution of fDGF. CONCLUSION: Urinary TIMP-2, but not IGFBP7, is a promising biomarker to predict the occurrence and duration of fDGF in DCD kidney transplant recipients. PMID- 30300283 TI - Importance of Hematopoietic Mixed Chimerism for Induction of Renal Allograft Tolerance in Nonhuman Primates. AB - BACKGROUND: Although induction of durable mixed chimerism is required for murine skin allograft tolerance, renal allograft tolerance has been achieved after induction of only transient mixed chimerism in nonhuman primates (NHPs) and humans. To better define the level/duration of chimerism required for stable renal allograft tolerance, we retrospectively analyzed these parameters and compared them with transplant outcomes in NHP combined kidney and bone marrow transplant (CKBMT) recipients. METHODS: Peripheral blood levels and duration of myeloid or lymphoid chimerism were retrospectively analyzed in 34 NHP CKBMT recipients which were divided into 3 groups: Tolerance (TOL), n=10; chronic antibody-mediated rejection (CAMR), n=12; and T cell-mediated rejection (TCMR), n=12. RESULTS: All 4 of the recipients that failed to develop any chimerism lost their allografts due to TCMR after discontinuation of immunosuppression (56 +/- 3 days). Among 30 recipients who successfully developed multilineage chimerism, 10 achieved immunosuppression-free survival (1258 +/- 388 days), 12 eventually developed CAMR (932 +/- 155 days), and 8 developed TCMR (82 +/- 10 days). The maximum level but not duration of lymphoid chimerism was significantly higher in TOL recipients compared with both CAMR (p=0.0159) and TCMR (p=0.0074). Conversely, the maximum myeloid chimerism was significantly higher in TOL than in TCMR (p=0.0469), but not in CAMR. ROC analyses revealed that lymphoid chimerism levels of 3.1% or greater could reliably predict long-term immunosuppression-free renal allograft survival (p<0.0001). CONCLUSIONS: This retrospective study confirmed that induction of chimerism is essential for long-term immunosuppression-free survival, which best correlates with lymphoid chimerism levels higher than 3.1%. PMID- 30300284 TI - Establishing a Core Outcome Measure for Life Participation: a Standardized Outcomes in Nephrology - Kidney Transplantation (SONG-Tx) Consensus Workshop Report. AB - BACKGROUND: Kidney transplantation confers substantial survival and quality of life benefits for many patients with end-stage kidney disease compared with dialysis, but complications and side-effects of immunosuppression can impair participation in daily life activities. Life participation is a critically important patient-reported outcome for kidney transplant recipients but is infrequently and inconsistently measured in trials. We convened a consensus workshop on establishing an outcome measure for life participation for use in all trials in kidney transplantation. METHODS: Twenty-five (43%) kidney transplant recipients/caregivers and 33 (57%) health professionals from 8 countries participated in 6 facilitated breakout group discussions. Transcripts were analyzed thematically. RESULTS: Four themes were identified. Returning to normality conveyed the patients' goals to fulfill their roles (ie, in their family, work, and community) and reestablish a normal lifestyle after transplant. Recognizing the diverse meaning and activities of 'life' explicitly acknowledged life participation as a subjective concept that could refer to different activities (eg, employment, recreation, family duties) for each individual patient. Capturing vulnerability and fluctuations posttransplant (eg, due to complications and side-effects) distinguished between experiences in the first year posttransplant and the long-term impact of transplantation. Having a scientifically rigorous, feasible and meaningful measure was expected to enable consistent and frequent assessment of life participation in trials in kidney transplantation. CONCLUSIONS: A feasible and validated core outcome measure for life participation is needed so that this critically important patient-reported outcome can be consistently and meaningfully assessed in trials in kidney transplantation to inform decision-making and care of recipients. PMID- 30300285 TI - Temporal Trends Associated with the Rise in Alcoholic Liver Disease Related Liver Transplantation in the United States. AB - BACKGROUND: In the United States, alcoholic liver disease (ALD) has recently become the leading indication for liver transplantation (LT). METHODS: Using the United Network for Organ Sharing registry, we examined temporal trends in adult liver transplant waitlist registrants and recipients with chronic liver disease (CLD) due to ALD from 2007 to 2016. RESULTS: From 2007 to 2016, ALD accounted for 20.4% (18 399) of all CLD waitlist (WL) additions. The age-standardized ALD WL addition rate was 0.459 per 100 000 US population in 2007; nearly doubled to 0.872 per 100 000 US population in 2016 and increased with an average annual percent change of 47.56% (95% CI: 30.33% to 64.72%).The ALD WL addition rate increased over twofold among young (18-39 years) and middle-aged (40-59 years) adults during the study period. Young adult ALD WL additions presented with a higher severity of liver disease including Model for End-Stage Liver Disease score compared to middle aged and older adults (> 60 years). The number of annual ALD WL deaths readily rose from 2014 to 2016, despite an overall annual decline in all CLD WL deaths. Severe hepatic encephalopathy, low BMI (< 18.5) and diabetes mellitus were significant predictors for 1-year waitlist mortality. CONCLUSION: ALD-related WL registrations and LT have increased over the past decade with a disproportionate increase in young and middle-aged adults. These subpopulations within the ALD cohort need to be evaluated in future studies to improve our understanding of factors associated with these alarming trends. PMID- 30300286 TI - THE OUTCOME OF ALLOGENEIC HEMATOPOIETIC STEM CELL TRANSPLANTATION FOR INHERITED DISEASES IS INFLUENCED BY HLA MATCH, YEAR OF TRANSPLANTATION AND IMMUNIZED FEMALE DONOR. AB - BACKGROUND: For many inborn errors of metabolism (IEM), allogeneic hematopoietic stem cell transplantation (HUSCT) is the only cure. METHODS: We report the outcome in 160 patients with inherited diseases, who were treated with HSCT in 3 decades. Median age was 3 years (range 0.1-63). Grafts were from matched related donors (MRDs, 56), matched unrelated donors (MUDs, 66), or HLA-mismatched donors (38). RESULTS: Graft failure (GF) occurred in 26 patients (16%), severe acute graft-versus-host disease (GVHD) in 9 (6%), and chronic GVHD in 23 (12%). Ten year survival was 64% before the year 2000 and 86% after that (p=0.01). Ten-year survival for MRD grafts was 90%, as opposed to 79% for MUD grafts and 56% for HLA mismatched grafts (p=0.03). In multivariate analysis, GF was associated with having an HLA-mismatched donor (p<0.05) or MUD (p=0.015) and with reduced intensity conditioning (p<0.01). Death was associated with year of transplant (p=0.015), having an HLA-mismatched donor (p<0.001), and being a male recipient from an immune female donor (p=0.05). CONCLUSIONS: The outcome after HSCT for IEM depends on HLA match, year and immune female donor. PMID- 30300287 TI - Nonalcoholic fatty liver disease: basic pathogenetic mechanisms in the progression from NAFLD to NASH. AB - Nonalcoholic fatty liver disease (NAFLD) represents a growing cause of chronic liver injury, especially in Western Countries, where it is becoming the most frequent indication for liver transplantation (OLTx). NAFLD encompasses a spectrum of diseases that from simple steatosis (pure NAFLD) can progress to Nonalcoholic steatohepatitis (NASH), cirrhosis and hepatocellular carcinoma (HCC). The pathogenesis of NAFLD and the mechanisms behind its progression to NASH have been extensively studied. However, while the processes that determine fat accumulation are mostly clear, the mechanisms associated with the progression of the disease are not fully characterized. In predisposed patients, lipid accumulation can promote lipotoxicity and mitochondrial dysfunction, thus triggering hepatocyte death, inflammation and fibrosis. The specific role of different lipids has been identified and free fatty acids as well as free cholesterol have been identified as toxic species. To make the picture more complex, the pathogenesis of NAFLD involves pathological connections between several organs, including the adipose tissue and the gut, with the liver. The "inflamed" adipose tissue plays a key role in the release of toxic lipids, while alterations in the gut-liver axis have been associated with the progression from NAFLD to NASH mediated by dysbiosis, alteration of intestinal barrier, and finally bacterial translocation, that can trigger proinflammatory and profibrogenetic pathways, finally leading to cirrhosis development. PMID- 30300288 TI - The Transplant Index (TI): A Novel Method To Predict Adult Liver Transplant Waitlist Outcomes. AB - BACKGROUND: The field of transplantation is shifting outcome priorities from 1 year survival to more comprehensive metrics including transplant rate and waitlist mortality. Identifying disenfranchised candidates (high waitlist death risk, low transplantation chance) can be a focus to improve outcomes. METHODS: Given waitlist outcomes, (continued waiting, death, and transplantation), we aimed to identify factors predicting the likelihood candidates would undergo transplant or death by performing multivariate competing risk analyses of 121 198 candidates in the United Network for Organ Sharing database. We incorporated these probabilities (likelihood of transplantation and waitlist death) into the transplant index (TI) to identify disenfranchised candidates (high likelihood of death, low likelihood of transplantation). RESULTS: Half of the patients had low incidences of death and transplantation within 90 days (TI-inactive). The remaining were stratified into 10 groups within a predictive index, the TI. Low TI groups (TI-10, 20, 30) had 90-day transplant rates of 50.8%, 41.6%, and 39.8% respectively, and their respective 90-day death rates were 22.8%, 15.1%, and 10.9%. High-TI groups (TI 80, 90, >90) had 90-day transplantation rates of 53.7%, 64.3%, and 73.9% respectively, and 90-day death rates of 5.9%, 6.5%, and 6.7% respectively. As TI increased, the likelihood of transplantation increased and that of death decreased. Low-TI groups represent the disenfranchised candidates. CONCLUSIONS: The TI identifies disenfranchised candidates on the adult liver transplant waitlist. This is the subgroup that would benefit the most from efforts to increase access to transplantation. PMID- 30300289 TI - Recommendations for management and treatment of nonalcoholic steatohepatitis. AB - The prevalence of nonalcoholic liver disease (NAFLD) is increasing worldwide in conjunction with the epidemic increase in obesity and metabolic risk factors. Consequently, NAFLD has become a leading indication for liver transplantation. While genetic factors play an important role in the pathogenesis of NAFLD, detrimental lifestyle trends favoring a calorically unrestricted diet rich in carbohydrates and unsaturated fat, prolonged sedentary periods or limited physical activity have major metabolic implications. In aggregate these physiological dysregulations constitute the main risk factors for the metabolic syndrome and NAFLD. The cornerstone of the treatment of NAFLD, is lifestyle changes, including modifications to diet and physical activity, to reduce body weight and liver fat, however adherence is notoriously poor and the epidemic of NAFLD continues to grow unimpeded. In the face of this unmet clinical need, the pharmacologic therapy of NAFLD has been expanding as the varied mechanistic pathways of NAFLD are elucidated. Beyond these approaches to treating NAFLD, the prevention of other liver diseases is additionally important. Chief among these is alcoholic liver disease, and heavy use is detrimental irrespective of underlying NAFLD. However, the impact of mild to moderate alcohol use in patients with mild or nonadvanced forms NAFLD is undefined. This article summarizes the results of the International Liver Transplant Society consensus meeting on NAFLD in liver transplantation. It describes the available evidence and provides consensus guidance on the lifestyle and pharmacologic therapies of NAFLD, and the consensus position on alcohol use in patients with NAFLD. PMID- 30300290 TI - Risperidone But Not Quetiapine Treatment Is Associated With Increased Appetite But Not Satiety Hormones in Children During An Oral Glucose Tolerance Test: A Pilot Study. AB - BACKGROUND: Second-generation antipsychotics (SGAs) are commonly used to treat children with mental health conditions (MHCs) but are associated with adverse effects including obesity, hypertension, dyslipidemia, and type 2 diabetes. The mechanisms underlying these complications are unknown, but it has been suggested that SGAs increase appetite leading to weight gain. The present objective was to perform a pilot study to investigate appetite and satiety hormones in SGA-treated (risperidone or quetiapine) and SGA-naive children with similar mental health conditions. METHODS: Oral glucose tolerance tests (OGTTs) were conducted in SGA naive (n = 18), risperidone-treated (n = 20), and quetiapine-treated (n = 16) children recruited from the British Columbia Children's Hospital Psychiatry Department. Over 5 time-points during the OGTT, appetite questionnaires using a visual analogue scale were administered, and blood was collected to measure ghrelin, peptide YY, glucose-dependent insulinotropic polypeptide, glucagon-like protein 1, leptin, and adiponectin. Mixed model analyses were conducted to examine between-group differences. RESULTS: The children were similar in age, psychiatric diagnosis, and global assessment of functioning scores. Body mass index z-scores were also similar between groups. Appetite was increased during the OGTT in the risperidone-treated compared with the SGA-naive group for 2 questions ("How strong is your desire to eat"; P = 0.003 and "How much food do you think you can eat"; P = 0.028). No differences in satiety hormones were observed between the 3 groups. CONCLUSIONS: Risperidone treatment in youth is associated with elevated appetite during an OGTT, with no differences in gut peptides or adipocytokines to explain risperidone's effect on appetite. Further research is needed to explore other mediators of weight gain and metabolic dysfunction in SGA-treated youth. PMID- 30300291 TI - Clinical Characteristics of Patients With Schizophrenia Who Successfully Discontinued Antipsychotics: A Literature Review. AB - PURPOSE/BACKGROUND: Although discontinuing antipsychotics clearly increases the risk of relapse in schizophrenia, some patients remain clinically well without continuous antipsychotic treatment. However, data on the characteristics of such patients are still scarce. METHODS/PROCEDURES: A systematic literature review was conducted to identify predictive factors for successful antipsychotic discontinuation in schizophrenia using PubMed (last search; June 2018) with the following search terms: (antipsychotic* or neuroleptic) AND (withdraw* or cessat* or terminat* or discontinu*) AND (schizophreni* or psychosis). The search was filtered with humans and English. Factors associated with a lower risk of relapse, when replicated in 2 or more studies with a follow-up period of 3 months or longer, were considered successful. FINDINGS/RESULTS: Systematic literature search identified 37 relevant articles. Mean relapse rate after antipsychotic discontinuation was 38.3% (95% confidence interval = 16.0%-60.6%) per year. Factors associated with a lower risk of relapse were being maintained on a lower antipsychotic dose before discontinuation, older age, shorter duration of untreated psychosis, older age at the onset of illness, a lower severity of positive symptoms at baseline, better social functioning, and a lower number of previous relapses. IMPLICATIONS/CONCLUSIONS: Although this literature review suggests some predictors for successful antipsychotic withdrawal in patients with schizophrenia, the very limited evidence base and unequivocally high relapse rates after discontinuation must remain a matter of serious debate for risk/benefit considerations.

PMID- 30300293 TI - Very Low-Dose Mirtazapine (7.5 mg) in Treatment of Acute Antipsychotic-Associated Akathisia. AB - BACKGROUND: Some evidence suggests that off-label use of mirtazapine (15 mg) is effective in treatment of acute antipsychotic-associated akathisia (AAA). We analyzed whether a lower dose of mirtazapine (7.5 mg) maintained its antiakathisia properties while exhibiting better tolerability in patients with schizophrenia and mood disorders who developed acute AAA. METHODS: Medical charts were retrospectively evaluated for 12 patients with AAA. All scored at least 2 (mild akathisia) on the Barnes Akathisia Rating Scale (BARS) and were treated with mirtazapine (7.5 mg) for a mean of 10.3 days. RESULTS: There was a statistically significant decrease in the BARS subjective, distress, and global (P < 0.01 to P < 0.001), but not objective (P = 0.63), subscales. Five participants (41.6%) fulfilled the predefined criterion of response, a decrease of at least 2 points on the BARS global subscale. The positive antiakathisia effect of mirtazapine was observed predominantly in aripiprazole-treated patients. Mirtazapine (7.5 mg) was well tolerated, and no clinically significant adverse effects, primarily drowsiness or increased appetite, were reported. CONCLUSIONS: A large-scale controlled evaluation is warranted to substantiate clinical utility of off-label use of mirtazapine (7.5 mg) for patients with AAA.

PMID- 30300295 TI - Age Impacts Olanzapine Exposure Differently During Use of Oral Versus Long-Acting Injectable Formulations: An Observational Study Including 8,288 Patients. AB - PURPOSE: Olanzapine is a commonly prescribed antipsychotic available as oral and long-acting injectable (LAI) formulations. Data are lacking on the use and safety of olanzapine-LAI in older patients. The aim of this study was to investigate the effect of increasing age on olanzapine exposure during oral versus LAI administration in a real-life setting. METHODS: This observational study was based on routine therapeutic drug monitoring data collected during 2005-2017. As a measure of exposure, absolute concentrations and concentration/dose ratios of olanzapine were defined as outcome variables. Linear mixed-model analyzes were used to allow for inclusion of multiple samples per patient and adjustment for covariate effects. RESULTS: Olanzapine concentrations and doses from 8,288 patients (21,378 measurements) were included. The number of patients on oral treatment was 7,893 (42%, 50 years or older), while 395 were using olanzapine-LAI (27%, 50 years or older). In contrast to oral use, where the dose-adjusted concentration of olanzapine increased significantly for patients 50 years or older (P < 0.001), increasing age had no effect on olanzapine concentration following LAI administration (P = 0.550). The effects of smoking habits and gender were equal in oral and olanzapine-LAI users. CONCLUSION: While the dose adjusted systemic exposure of olanzapine increases by age after oral administration, these novel findings from a large patient population show that systemic exposure of olanzapine-LAI is unaffected by age, probably due to the lacking influence of age-related changes in gastrointestinal absorption and/or presystemic metabolism. From a pharmacokinetic point of view, it is therefore no reason to restrict the use of olanzapine-LAI in older patients requiring long term treatment. PMID- 30300297 TI - The mysteries of menopause and urogynecologic health: clinical and scientific gaps. AB - OBJECTIVES: A significant body of knowledge implicates menopausal estrogen levels in the pathogenesis of the common pelvic floor disorders (PFDs). These health conditions substantially decrease quality of life, increase depression, social isolation, caregiver burden, and economic costs to the individuals and society. METHODS: This review summarizes the epidemiology of the individual PFDs with particular attention to the understanding of the relationship between each PFD and menopausal estrogen levels, and the gaps in science and clinical care that affect menopausal women. In addition, we review the epidemiology of recurrent urinary tract infection (rUTI)-a condition experienced frequently and disproportionately by menopausal women and hypothesized to be potentiated by menopausal estrogen levels. RESULTS: The abundance of estrogen receptors in the urogenital tract explains why the natural reduction of endogenous estrogen, the hallmark of menopause, can cause or potentiate PFDs and rUTIs. A substantial body of epidemiological literature suggests an association between menopause, and PFDs and rUTIs; however, the ability to separate this association from age and other comorbid conditions makes it difficult to draw definitive conclusions on the role of menopause alone in the development and/or progression of PFDs. Similarly, the causative link between the decline in endogenous estrogen levels and the pathogenesis of PFDs and rUTIs has not been well-established. CONCLUSIONS: Innovative human studies, focused on the independent effects of menopausal estrogen levels, uncoupled from tissue and cellular senescence, are needed. PMID- 30300298 TI - Clinical application and mid-term results of modified vaginal closure: pelvic symptoms, quality of life, satisfaction, and regret rate. AB - OBJECTIVE: To evaluate the safety and efficacy of a modified vaginal closure in older women with severe pelvic organ prolapse (POP) with respect to symptoms, quality of life, postoperative satisfaction, regret rate, and complications METHODS:: From March, 2014 to December, 2016, in all, 32 women were enrolled in the study. All the participants underwent a modified vaginal closure. Records were reviewed to collect demographic characteristics and perioperative parameters. The Pelvic Floor Distress Inventory-short form 20 (PFDI-20) and the Short Form 36 Health Survey Profile (SF-36) were used to evaluate pelvic symptoms and self-perceived quality of life, respectively, 6 months postoperatively and at the latest follow-up. The Patient Global Impression of Change (PGI-C) was used to estimate the satisfaction. The satisfaction and regret rates were assessed at the latest follow-up. RESULTS: After an average follow-up period of 23 months (range 8-41 months), none of the 32 women experienced recurrence of prolapse that required reoperation. During follow-up, significant improvements were observed in the Pelvic Organ Prolapse Distress Inventory (POPDI-6), Urinary Distress Inventory (UDI-6), and SF-36 results (P < 0.001). However, the Colorectal-Anal Distress Inventory (CRADI-8) results did not improve significantly (P = 0.074). None of the participants regretted undergoing this procedure, and the PGI-C indicated a satisfaction rate of 93.8%. CONCLUSIONS: The modified vaginal closure showed a positive impact on POP and urinary symptoms, and consequently improved quality of life of the 32 participants. This procedure achieved a relatively high satisfaction rate and a low regret rate. PMID- 30300299 TI - High and dry: recognizing the impact of genitourinary syndrome of menopause. PMID- 30300300 TI - Tissue-selective estrogen complex for women who experience breast discomfort or vaginal bleeding when on hormone therapy. AB - OBJECTIVE: The objective of this study was to evaluate the effects of switching from hormone therapy to tissue-selective estrogen complex (TSEC) in women who experience vaginal bleeding or breast discomfort. METHODS: This retrospective cohort study included 82 postmenopausal women who received TSEC after switching from another hormone therapy due to adverse events. Changes in symptoms and imaging after switching to TSEC were evaluated. RESULTS: The mean age was 56.9 years. The women were switched to TSEC due to vaginal bleeding in 56.1% and breast discomfort in 47.6% (multiple choices were allowed). After the switch, almost all women (97.6%) experienced an improvement in adverse events. However, 27% of the women had worsening of vasomotor symptoms, which was more common when hormone therapy was changed from 2 mg of estradiol (41.7%) compared with 1 mg of estradiol (16.7%), 0.625 mg of conjugated estrogen (30%), or tibolone (12.5%). Images of breast lesions and fibroids before the switch were assessed, showing no change in most women. CONCLUSIONS: This study suggests that TSEC is a good option for women who have breast discomfort or persistent bleeding during other hormone therapy when taking into account the differences in estrogen dose. PMID- 30300301 TI - Age at natural menopause and life expectancy with and without type 2 diabetes. AB - OBJECTIVE: Effective interventions of future health care require a better understanding of the health risks associated with early onset of menopause and diabetes, but the necessary data are scarce. Little quantitative information is available about the combined association of early menopause and diabetes on life expectancy and the number of years lived with and without diabetes. METHODS: We included 3,650 postmenopausal women aged 45+ years from the Rotterdam Study, a prospective population-based cohort study. Age at menopause categories were defined as follows: early (<=44 y old), normal (45-54 y old), and late (>=55 y old). For life table calculations, we used prevalence, incidence rates, and hazard ratios for three transitions (free of diabetes to diabetes, free of diabetes to death, and diabetes to death) stratifying by age at menopause categories and adjusting for confounders. RESULTS: Compared with late menopause, the difference in life expectancy for women who experienced early menopause was 3.5 (95% CI, -6.6 to -0.8) years overall and -4.6 (95% CI, -8.9 to -0.9) years without diabetes. Compared with age at normal menopause, the difference in life expectancy for women who experienced early menopause was -3.1 (95% CI, -5.1 to 1.1) years overall and -3.3 (95% CI, -6.0 to -0.6) years without diabetes. CONCLUSIONS: Women who experienced early menopause lived less long and spent fewer years without diabetes than women who experienced normal or late menopause. PMID- 30300302 TI - In Reply. PMID- 30300303 TI - The Relationship Between Binocular Visual Field Loss and Various Stages of Monocular Visual Field Damage in Glaucoma Patients. AB - PURPOSE: To investigate the effects of monocular visual field loss severity on binocular visual field loss in primary angle-closure glaucoma, primary open angle glaucoma and normal tension glaucoma patients. METHODS: In this observational cross-sectional study, 250 glaucoma patients and 31 healthy participants were assigned to groups according to the stage of monocular visual field loss in both eyes; normal, early, moderate or severe. Binocular visual field assessments were determined via integrated visual field and Esterman binocular visual evaluations. Monocular and binocular visual field parameters were compared within and among groups. RESULTS: In patients with one eye at normal or early stage and the other at severe stage, the average integrated mean deviations were (mean [SD]), -1.67 (1.39) dB, and -3.27 (2.05) dB, respectively, and the average Esterman scores were >95% (99.17% [1.89%], 96.08% [3.99%], respectively). Where both eyes had progressed to moderate or severe damage (moderate/moderate, moderate/severe, or severe/severe), the average integrated mean deviations were worse than -6?dB, and the mean Esterman scores in the moderate/moderate and the moderate/severe damage groups were still >90% (94.20%[5.96%], 94.32%[4.95%], respectively), but it dropped rapidly from >90% to 68.44% (26.27%) when both eyes were at severe stage. CONCLUSIONS: The binocular visual field can remain relatively intact provided one eye is at normal or early stage. Significant binocular visual field defects measured by integrated mean deviation were evident when both eyes had progressed to moderate or severe stage, and significant Esterman binocular visual field defects were only detected when both eyes had advanced to severe stage. PMID- 30300304 TI - A Prospective Evaluation of the Repeatability and Reliability of New Steady-state Pattern Electroretinogram Parameters. AB - PURPOSE: The purpose of this study was to determine the repeatability and reproducibility of a new Pattern Electroretinography (PERG) device in healthy subjects. METHODS: A total of 40 eyes of 20 healthy subjects (45.6+/-6.8 y, 70% female) were enrolled in this prospective study. Steady-state PERG were recorded using the Diopsys NOVA (Diopsys Inc., NJ) to obtain the Magnitude, MagnitudeD, MagnitudeD/Magnitude Ratio, and Signal to Noise Ratio. Subjects underwent 2 "contrast sensitivity" protocols with the same electrodes and 2 after changing electrodes, by a single examiner. Eyes were stimulated separately using high and low contrast patterns. The same examination was repeated by a different operator following the same protocol 6 months after the baseline measures. Repeatability and reproducibility of the readings were calculated using intraclass correlation coefficient (ICC). A Bland-Altman plot was used to analyze the agreement between measures. RESULTS: ICC of Magnitude, MagnitudeD, MagnitudeD/Magnitude ratio, and SNR were 0.87, 0.81, 0.36, and 0.81, respectively between measures taken with the same electrodes (repeatability). After changing electrodes, ICC of the Magnitude, MagD, MagD/Mag ratio, and SNR were 0.79, 0.85, 0.51, and 0.83, respectively during the same session as baseline measures, and 0.87, 0.85, 0.40, and 0.76 when repeated after 6 months (reproducibility). The variability of MagD/Mag ratio increased with successive test repetitions. CONCLUSIONS: Mag, MagD, and SNR were repeatable and reproducible, whereas the MagD/Mag ratio was less repeatable and reproducible. These results suggest that the former parameters are sufficiently reliable to be used in clinical practice. PMID- 30300305 TI - Associations among Pregnancy, Parturition, and Open-angle Glaucoma: Korea National Health and Nutrition Examination Survey 2010-2011. AB - PURPOSE: To investigate the association between factors associated with parturition and open-angle glaucoma (OAG) in Korean females. METHODS: A population-based, cross-sectional survey was performed from the Korean National Health and Nutrition Examination Survey from 2010-2011 and enrolled postmenopausal female participants (n=1798). We obtained information on demographics, comorbidities, and health-related behaviors and performed comprehensive ophthalmic examinations. Multivariate regression analysis was used to assess the correlation between pregnancy and delivery and the prevalence of OAG in all enrolled subjects. RESULTS: The prevalence of OAG among study participants was 6.42%. There was a significant difference in the number of deliveries and age at first delivery between the OAG group and the non-glaucoma group. In multiple linear regression models adjusted for age, hypertension, and intraocular pressure only pregnancy 1 was associated with higher risk of OAG compared with pregnancy 2 (P=0.023). Subjects who had three or four deliveries were at higher risk of OAG compared with subjects with two deliveries (P=0.027). An age at first delivery of 16-20 years or 21-23 years was associated with increased OAG risk compared with the reference group (P<0.05). CONCLUSIONS: A history of three or more deliveries and an age at first delivery younger than 23 years were associated with increased risk of OAG. These results suggest that changes or events during the period from pregnancy to delivery affect the development of glaucoma. PMID- 30300306 TI - Impact of Head Tilt on Optical Coherence Tomography Image Orientation. AB - PURPOSE: Head tilt can have an impact on the orientation of posterior pole images. We conducted this study to determine the effect of head tilt on image orientation measured by the fovea-Bruch's membrane opening (FoBMO) angle with optical coherence tomography (OCT) imaging. METHODS: The study included 56 healthy subjects with mean (range) age of 33 (18 to 61) years. The dominant eye was first determined. To measure head tilt, a smartphone with a built-in gyroscope was affixed to the subject's head with adjustable straps. OCT imaging was performed in both eyes (in randomized order) at 0, 5, and 10 degrees of head tilt in the direction of the imaged eye (ipsilateral head tilt), and then in the opposite direction (contralateral head tilt). For each image, the device software determined Bruch's membrane opening center and the foveal pit from which the FoBMO angle was derived. RESULTS: Thirty-eight (68%) subjects were right eye dominant and 18 (32%) were left eye dominant. Each 1 degree head tilt resulted in a mean change of 0.76 degree in the FoBMO angle (P<0.01), with no significant difference in effect between the 2 eyes (P=0.72). The magnitude of the effect increased from 5 to 10 degrees, and was similar for both ipsilateral and contralateral head tilt. Ocular dominance did not modulate the effect of head tilt (P=0.42). CONCLUSIONS: Head tilt significantly affects OCT image orientation as measured by the FoBMO angle, presumably because cyclotorsion is not fully compensatory. The magnitude and direction of the effect does not depend on the dominant eye. PMID- 30300307 TI - Outcomes of Laser Goniopuncture Following Non-penetrating Deep Sclerectomy with Mitomycin C: A Large Retrospective Cohort Study. AB - PURPOSE: To report on the frequency, efficacy, and safety of laser goniopuncture (LGP) in lowering IOP following mitomycin-C augmented non-penetrating deep sclerectomy (NPDS) in a large cohort of eyes. METHODS: Monocenter database retrospective study. We reviewed records of 350 eyes that underwent NPDS between 2009 and 2015, at National Ophthalmology Center of XV-XX (Paris, France). We recorded incidence of LGP, time between NPDS and LGP, IOP efficacy and the occurrence of complications. The success of the LGP was defined by an IOP lower than 15?mmHg without hypotonic treatment. RESULTS: Mean postoperative follow-up period was 19+/-15.9 months after the NPDS (range:6-58). LGP was performed in 125 eyes (35.7%) in a mean time after NPDS of 7.4+/-7.6 months (range: 1?d-36?mo). Most LGP procedures were performed during the first year (97 eyes, 77.6%). The survival analysis using the Kaplan-Meier method showed a 50% incidence of LGP by 2 years. The mean IOP before LGP was 23.8+/-7.1?mmHg. LGP resulted in immediate (Day 8) and significant IOP lowering by up to 15+/-6.8?mmHg. This decrease was maintained throughout the follow-up period and the Kaplan-Meier survival success rate at two years was 48.9% (95% CI=39.4-60.8). The most common complication was iris incarceration which occurred in 22 eyes of 125 LGP (17.6%). CONCLUSIONS: Most of the eyes which underwent NPDS may require LGP to reduce IOP to below the target value. Most often this procedure was performed in the first year after NPDS (77,6%). LGP lowered IOP below 15?mmHg without any hypotonic medication for at least two years in 50% of cases. Goniopuncture is associated with potentially significant complications, of which the most common is iris incarceration. We identified two predicting factors for iris incarceration: high IOP before LGP and early LGP after NPDS. PMID- 30300308 TI - Panscleritis as an Unusual Complication of Gonioscopy-assisted Transluminal Trabeculotomy. AB - PURPOSE: To report a case of panscleritis after gonioscopy-assisted transluminal trabeculotomy (GATT). METHODS: We describe the case of a 33-year-old man with a history of unilateral anterior uveitis and glaucoma, who developed panscleritis after GATT surgery. RESULTS: Uneventful GATT surgery was performed in a glaucomatous left eye. On the second postoperative day, the patient developed tenderness on palpation of the eye. Ophthalmic examination revealed significant diffuse hyperemia, elongated and tortuous upper bulbar conjunctival/scleral vessels, and exudative retinal detachment at the superior nasal quadrant, with diffuse scleral thickening. The patient was diagnosed as having panscleritis, which was attributed to the GATT surgery. Although the scleritis resolved completely with intravenous and oral methylprednisolone treatment, localized retinal detachment persisted. CONCLUSION: Surgery-induced posterior scleritis may occur following minimally invasive glaucoma surgeries such as GATT. Control of uveitis for at least 3 months prior to surgery is indicated in patients with uveitis if GATT surgery is planned.

PMID- 30300309 TI - Primary Angle Closure Glaucoma with Normal Intraocular Pressure at the First Visit: Its Prevalence and Ocular Characteristics. AB - PURPOSE: To investigate the prevalence of normal intraocular pressure (IOP) at first visit among patients with primary angle closure glaucoma (PACG) and their ocular characteristics. PATIENTS AND METHODS: We retrospectively reviewed patients with PACG in a referral center. According to untreated IOP, we divided PACG eyes into two groups: those with normal IOP and those with high IOP (>21?mmHg) at the first visit. RESULTS: One hundred sixty eyes of 160 Korean PACG patients were included. Sixty percent (97/160) of the patients had normal IOP at their first visit. The PACG patients with initially normal IOP had significantly longer axial length (mean+/-standard deviation [SD] 22.99+/-0.76 vs. 22.74+/ 0.61) and deeper "true" anterior chamber depth (ACD) (2.09+/-0.27 vs. 1.82+/ 0.33) than those with initially high IOP (both P<0.05). Multiple logistic regression revealed that deeper "true" ACD (per 0.1?mm, odds ratio [OR] 1.38) and more hyperopic refractive errors (OR 1.48) were independent predictors of initially normal IOP in PACG eyes (P<0.05). The prevalence of disc hemorrhage was higher in PACG patients with initially normal IOP than in those with initially high IOP (29.9% vs. 14.3%, P=0.029). CONCLUSION: Sixty percent of patients with PACG had normal IOP at their first visit. This suggests that without gonioscopy clinicians may misdiagnose PACG as normal tension glaucoma. ACD measurement can aid the diagnosis of PACG because even PACG eyes with initially normal IOP have shallow ACD. PMID- 30300311 TI - PROGRESSION OF SCOTOPIC SINGLE-FLASH ELECTRORETINOGRAPHY IN THE STAGES OF CAPN5 VITREORETINOPATHY. AB - PURPOSE: To characterize the changes found in the electroretinography (ERG) recordings of patients with autosomal dominant neovascular inflammatory vitreoretinopathy and correlate with clinical stages of the disease. METHODS: Retrospective chart review. Bright- and dim-flash full-field scotopic, photopic, and 30-Hz flicker ERGs were obtained according to international standards. The scotopic ERGs were further processed to analyze the oscillatory potential. The patient described in the case report underwent full ERG testing; five patients composed the archival case series data and included scotopic ERG recordings. RESULTS: Stage I autosomal dominant neovascular inflammatory vitreoretinopathy is characterized by a decrease in the b-wave amplitude on scotopic flash ERG and the disappearance of late OPs; however, the a-wave amplitude is normal. In Stage II, attenuation of early OPs and the c-wave are observed in scotopic ERG recordings, but both a- and b-wave amplitudes are unchanged. For patients in Stage III, there is a continued decline of both a- and b-wave amplitudes in scotopic ERG recordings. There was a loss of recordable scotopic ERG response in patients with Stage IV disease. CONCLUSION: Electroretinography may be valuable in determining optimal timing for therapeutic intervention and response before loss of recordable retinal function in CAPN5 vitreoretinopathy. PMID- 30300312 TI - PNEUMATIC COMPACTION TREATMENT OF ACUTE SUBFOVEAL HEMORRHAGE AFTER BLUNT TRAUMA IN A PATIENT WITH ANGIOID STREAKS ASSOCIATED WITH PSEUDOXANTHOMA ELASTICUM. AB - PURPOSE: To report a case of photoreceptor restitution and vision improvement with pneumatic compaction treatment of acute subfoveal hemorrhage in a patient with angioid streaks associated with pseudoxanthoma elasticum, observed by sequential fundus photography, spectral domain optical coherence tomography, and fundus autofluorescence. METHODS: Findings on initial and sequential clinical examinations, fundus autofluorescence, and spectral domain optical coherence tomography are presented, before and after pneumatic compaction, demonstrating the course of compaction and resolution of subfoveal hemorrhage and status of the foveal ellipsoid zone and external limiting membrane. Sequential improvements in oxygen and nutrient diffusion are calculated using Fick's law of diffusion. Findings are compared with previous reports regarding the natural history of similar patients. RESULTS: Rapid compaction of subfoveal hemorrhage occurred, resulting in an 89% improvement in oxygen diffusion in 15 days. No centrifugal movement of subfoveal hemorrhage occurred, potentially minimizing photoreceptor shearing injury. Ultimately, resorption of all hemorrhage occurred with reestablishment of the foveal ellipsoid zone and external limiting membrane and minimal juxtafoveal subretinal fibrosis; best-corrected visual acuity improved to 20/40: an advantage over natural history based on published reports. CONCLUSION: Pneumatic compaction in patients with acute subfoveal hemorrhage secondary to angioid streaks associated with pseudoxanthoma elasticum compacts subfoveal hemorrhage, therefore improving oxygen and nutrient diffusion. This potentially spares foveal photoreceptors of ischemic and shearing injury, theoretically reducing subfoveal fibrosis and improving vision prognosis in these patients. PMID- 30300314 TI - NEUROTROPHIC KERATOPATHY AFTER RETINAL DETACHMENT SURGERY COMBINED WITH ENDOLASER PHOTOCOAGULATION. AB - PURPOSE: To report neurotrophic keratopathy after vitreoretinal surgery combined with aggressive photocoagulation. METHODS: We report a series of three cases with neurotrophic keratopathy after pars plana vitrectomy combined with endolaser photocoagulation. RESULTS: Three patients who had pars plana vitrectomy with different indications were identified. On follow-up, all patients were diagnosed with neurotrophic keratopathy. Two of the patients underwent amniotic membrane transplantation for the treatment of resistant neurotrophic corneal ulcers. CONCLUSION: Neurotrophic keratopathy may occur after pars plana vitrectomy. The possible mechanism is long ciliary nerve damage related to the extensive endolaser photocoagulation. PMID- 30300313 TI - BEARING DOWN ON TREPONEMES: AN ATYPICAL PRESENTATION OF SYPHILITIC UVEITIS. AB - PURPOSE: To present an atypical case of syphilis that presented with findings concerning for endocarditis and valsalva retinopathy. METHODS: History and clinical examination of 42-year-old white man who presented to the emergency department with acute onset vision changes associated with gastrointestinal symptoms, otalgia, and constitutional symptoms. RESULTS: The review of this case highlights the atypical nature in which syphilis can present and can remain undiagnosed even in the face of extensive workups for other systemic conditions. CONCLUSION: We present a case of syphilis in a patient with multiorgan involvement in whom the diagnosis was made based on atypical ocular examination findings. PMID- 30300315 TI - ADULT-ONSET VITELLIFORM MACULAR DYSTROPHY SECONDARY TO A NOVEL IMPG2 GENE VARIANT. AB - PURPOSE: To report a case of adult-onset vitelliform macular dystrophy in a patient who was found to have a previously unreported variant of the IMPG2 gene. METHODS: Case report. RESULTS: A 65-year-old white woman with no significant medical or ocular history presented with a complaint of persistent wavy vision for 10 months. On funduscopic examination, bilateral vitelliform lesions of approximately 1 mm in the right eye and 0.5 mm in the left eye were evident, with no choroidal neovascularization in either eye. The patient was diagnosed with adult-onset vitelliform macular dystrophy. Genetic testing revealed a single likely pathogenic variant of the IMPG2 gene that may explain the examination findings. CONCLUSION: Adult-onset vitelliform macular dystrophy is a common and relatively benign condition occurring in approximately 1 in 8,000 individuals. Although vitelliform lesions can be a manifestation of systemic diseases or be idiopathic, in a minority of patients, genetic predisposition may play a role. Mutations in four particular genes BEST1, PRPH2, IMPG1, and IMPG2 have been associated with some cases of adult-onset vitelliform macular dystrophy, with this particular gene variant of IMPG2 being previously unreported. PMID- 30300316 TI - Effect of Long-Term Polytrauma on Ventilator-Induced Diaphragmatic Dysfunction in a Piglet Model. AB - INTRODUCTION: Mechanical ventilation is known to activate oxidative stress and proteolytic pathways in the diaphragm. Trauma by inducing inflammation and activating proteolytic pathways may potentiate the effects of mechanical ventilation on the diaphragm. In a blunt chest trauma with concomitant injuries we tested the hypothesis that trauma via inflammation further activates the proteolytic pathways and worsens atrophy in the diaphragm. MATERIAL AND METHODS: Piglets were separated into 2 groups and underwent 72hrs of mechanical ventilation. One group received a polytrauma (PT) by unilateral femur fracture, blunt chest trauma with lung contusion, laparotomy with standardized liver incision and a predefined haemorrhagic shock. The second mechanically ventilated group (MV) did not receive any trauma. A non-ventilated group (Con) served as control.Diaphragmatic fibre dimensions, Western Blot analyses of proteolytic pathways and lipid peroxidation and mRNA levels of cytokines and NFkB subunit p65 were measured. RESULTS: Active Caspase-3 was significantly increased in MV (p = 0.019), and in PT (p = 0.02) compared to Con. NFkB subunit p65, was up-regulated in PT (p = 0.010) compared to Con. IL-6 mRNA increased significantly in PT compared to Con (p = 0.0024) but did not differ between Con and MV. CONCLUSION: Trauma and mechanical ventilation induced proteolysis and atrophy in the diaphragm, but only polytrauma induced an inflammatory response in the diaphragm. The additional traumatic inflammatory stimulus did not increase the levels of the pre-mentioned variables. These data underline that inflammation is not a major contributor to VIDD. TRIAL REGISTRY NUMBER: AZ 84-02.04.2014.A265 (Landesamt fur Natur-, Umwelt- und Verbraucherschutz, LANUV NRW, Germany). PMID- 30300317 TI - A New Echocardiographic Tool for Cardiac Output Evaluation: An Experimental Study. AB - BACKGROUND: The correlation between cardiac output (CO) evaluated by echocardiography and CO measured by thermodilution (COth) varies according to different studies. A new transthoracic echocardiography (TTE) tool allows automatic calculation of the subaortic velocity time index (VTIauto) and CO (COauto). The main objective was to evaluate the correlation between COth and COauto in an anesthetized, ventilated piglet hemorrhagic shock (HS) model. The secondary objectives were to evaluate the correlation between COth and CO evaluated by manual measurements of VTI, and the preload-dependency of VTIvaresp. METHODS: Eighteen piglets were bled until mean arterial pressure reached 40 mmHg. Controlled hemorrhage was maintained for 30 min before a resuscitation phase. CO was measured by Pulse index Contour Cardiac Output (PiCCO) thermodilution methods. At each time of the experiment, three VTI values were measured (min, med, max) and the average value was calculated. COs were calculated by TTE (COmax, COmed, COmin, COave). RESULTS: For the 204 measures attempted, the success rate was 197 (97%) manually and 122 (60%) automatically (p < 0.01). The correlation coefficients (r) between COth and, respectively, COauto, COave, COmax, COmed, and COmin were: 0.83 (95%CI [0.76; 0.88]; p < 0.01), 0.54 (95%CI [0.43; 0.63]; p < 0.01), 0.43 (95%CI [0.31; 0.54]; p < 0.01), 0.58 (95%CI [0.48; 0.67]; p < 0.01), and 0.52 (95%CI [0.41; 0.62]; p < 0.01). CONCLUSION: In an experimental model of HS, a new ultrasound tool, COauto, seems better correlated with COth than manual echocardiographic measurements. PMID- 30300318 TI - Exploring the Protective Role and the Mechanism of Sphingosine 1 Phosphate in Endotoxic Cardiomyocytes. AB - FTY720 is a sphingosine 1 phosphate (S1P) receptor agonist approved for the treatment of multiple sclerosis (MS), which is a chronic inflammatory autoimmune disorder. Sepsis is a complex syndrome associated with progressive endotoxemic developments, which finally leads to damage of multiple organs, including the heart. In critical patients, cardiovascular dysfunction due to sepsis is a major cause of death. Previous studies have shown an association between S1P and cardioprotection in the situation of ischemia reperfusion and myocardial infarction. Therefore, we will study the role of S1P towards endotoxic cardiomyocytes. Different doses of FTY720 were applied or not to endotoxic cardiomyocytes. The concentration of inflammatory cytokines, including TNF-alpha, IL-1beta, IL-6 and IL-10, was measured by enzyme-linked immuno sorbent assay (ELISA). Western blotting (WB) was used to analyze the downstream signaling pathways. We discovered that FTY720 reduced the levels of TNF-alpha and IL-6 through the NF-KappaB pathway, inhibited the expression of caspase-3 and activated both AKT and ERK1/2. Additionally, the activation of AKT and ERK 1/2 could be inhibited by the S1P1 and S1P3 receptor antagonist VPC23019. Therefore, we infer that S1P exerts a protective effect towards endotoxic cardiomyocytes by decreasing the levels of TNF-alpha and IL-6, regulating apoptotic and survival signaling pathway. The S1P1 and S1P3 receptors are involved in the prosurvival signal activation.This is an open access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY NC-ND), where it is permissible to download and share the work provided it is properly cited.

PMID- 30300319 TI - Comparison of Real-Time and Static Ultrasonography Diagnoses for Detecting Incidental Diffuse Thyroid Disease: A Multicenter Study. AB - This study aimed to compare diagnostic accuracy of real-time and static ultrasonography (US) for differentiating diffuse thyroid disease (DTD) from normal thyroid parenchyma (NTP). At 4 participating institutions, 203 patients underwent real-time thyroid US before thyroid surgery. For static US, the same radiologists retrospectively evaluated US findings on a picture archive and communication system after 4 weeks. In real-time and static US diagnoses, US category included no DTD, indeterminate, suspicious for DTD, and DTD. We investigated the diagnostic accuracy of real-time and static US with a receiver operating characteristic curve analysis using histopathologic results as the reference standard. Histopathologic results exhibited NTP (n = 139), Hashimoto thyroiditis (n = 24), non-Hashimoto lymphocytic thyroiditis (n = 33), and diffuse hyperplasia (n = 7). Of 203 patients, there were significant differences in echogenicity, echotexture, glandular margin, and vascularity of the thyroid gland and US category between NTP and DTD groups in both real-time and static US diagnoses (P < 0.001). The diagnostic indices of real-time and static US were highest when the cutoff criterion was chosen as 1 or more abnormal US features. In addition, US category was the only feature with a significant difference between DTD and NTP groups regardless of the practical experience. The receiver operating characteristic curve analysis showed that real-time US was superior to static US in the diagnostic accuracy; however, there was no significant difference (P = 0.09). In conclusion, real-time and static US can be helpful for detecting incidental DTD by using US classification based on abnormal US features. PMID- 30300320 TI - Diagnosing Polyps on Transvaginal Sonography: Is Sonohysterography Always Necessary? AB - BACKGROUND: Endometrial polyps are localized overgrowth of glands, stroma, and blood vessels and reported in 13% to 50% of women with dysfunctional uterine bleeding. Transvaginal ultrasound (TVUS) is the initial noninvasive modality of choice for the evaluation of endometrial polyps. The addition of intrauterine contrast by adding saline during saline infusion sonohysterography (SIS) has been reported to improve diagnostic accuracy in detecting of endometrial polyps. Given all the technical advances in ultrasound instrumentation and technology over the last 10 years, we wanted to revisit the diagnostic accuracy and associated confidence level of TVUS and SIS for detecting endometrial polyps. OBJECTIVE: The aims of this study was to determine the diagnostic accuracy of TVUS in detecting endometrial polyps in patients with abnormal uterine bleeding or infertility and to determine if SIS is necessary when the level of confidence that a polyp is present is high. MATERIALS AND METHODS: A total of 144 patients who underwent both TVUS and SIS for the evaluation of abnormal uterine bleeding and infertility were retrospectively identified and independently reviewed by 2 blinded readers. Examinations were graded as polyps absent, equivocal for polyps, and polyps definitely present. Interreader agreement for TVUS grade was assessed using Cohen kappa. Hysteroscopy and histopathology were used as the reference standard for the final diagnosis. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value were calculated, and confidence intervals (CIs) were computed. RESULTS: From the combined assessments of both readers (288 reads), 24.7% were definitively positive for polyps, 47.2% were negative, and 28.1% were equivocal by TVUS. Interreader agreement was good with a kappa of 0.66 (95% CI, 0.56-0.76). Among the 108 reads where hysteroscopy/histopathology results were available, even when diagnostic confidence for the presence of polyps was high, TVUS had a PPV of 65.2% (95% CI, 42.1%-88.9%). This PPV was significantly lower than the corresponding PPV of SIS of 88.5% (95% CI, 77.4 100.0%; P = 0.021 for the difference). CONCLUSION: Saline infusion sonohysterography has better diagnostic accuracy for the detection and exclusion of endometrial polyps than TVUS, even in cases where the diagnostic confidence for the presence of polyps is high. Saline infusion sonohysterography may still be needed to confirm a TVUS diagnosis for polyps to limit the number of negative hysteroscopies. PMID- 30300321 TI - Assessment of Subclinical Atherosclerosis in Vitamin D Deficiency. AB - PURPOSE: Patients with vitamin D deficiency (VDD) have potential to have increased cardiovascular morbidity and mortality. In this study, we aimed to discover the findings of early atherosclerosis in patients with VDD by measuring carotid intima-media thickness (CIMT) and epicardial fat thickness (EFT). MATERIALS AND METHODS: The study population includes 52 patients with VDD (n = 30 [57% female], mean +/- SD age 54.28 +/- 8.77 years, mean +/- SD serum 25 hydroxyvitamin D (25 [OH] D) 11 +/- 2.4 ng/mL) and 82 participants for control group (n = 52 [63.4% female], mean +/- SD age 56.40 +/- 7.90 years, mean +/- SD serum (25 [OH] D) 53 +/- 4.2 ng/mL) who have no cardiovascular disease. Carotid intima-media thickness was assessed by using ultrasonography, and EFT was measured on the free wall of the right ventricle at end diastole from the parasternal long-axis views by standard transthoracic 2-dimensional echocardiography. RESULTS: Both CIMT and EFT were significantly higher in patients with VDD compared with controls (0.75 +/- 0.16 mm vs 0.68 +/- 0.21 mm, P < 0.05, and 0.66 +/- 0.15 cm vs 0.56 +/- 0.15 cm, P < 0.001). CONCLUSIONS: Patients with VDD seem to have increased CIMT and EFT, which are predictors of atherosclerotic process. Further studies are needed to confirm these results.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

AB - One of the most useful sonographic signs of acute abdominal inflammation is the identification of increased echogenicity of the surrounding fat. Hyperechoic fat results from vasodilation and edema extending from an adjacent source of infection or inflammation. These changes are mediated by such factors such as bradykinin, histamine, and various cytokines. The recognition of hyperechoic fat on sonography may be an important indicator of the primary source of pathology. In addition, it often reflects a more advanced degree of transmural pathology, such as "walled-off" perforation of a hollow viscus. This pictorial essay will present a variety of examples of hyperechoic inflamed fat involving different abdominal organs and will illustrate the diagnostic value of this finding. PMID- 30300323 TI - Quantitative Assessment of Palatine Tonsils in Healthy Children and Adolescents With Shear-Wave Elastography. AB - The normal elasticity and velocity values for palatine tonsils (PTs) in healthy children and adolescents were defined using shear wave elastography, and the relationship with potential factors affecting these values was assessed. This prospective study included a total of 80 cases with ages ranging from 3 to 17 years. Sex, age, and body mass index (BMI) were recorded. Elasticity and velocity measurements of both PTs and the relationship with basic descriptive data were investigated. For statistical analyses, independent-samples t tests and Spearman rho (r) correlation coefficient were used. Quantitative variables are shown as the mean +/- SD, and categorical variables are shown as n (%). The mean age was 10.6 +/- 6.4 years, and the mean BMI was 17.40 +/- 4 kg/m. The mean elasticity and velocity values were 9.38 +/- 1.27 kPa and 1.76 +/- 0.11 m/s for the right PT and 9.57 +/- 1.43 kPa and 1.79 +/- 1.04 m/s for the left PT, respectively. The mean tonsil volume was 2.44 mL for the right PT and 2.36 mL for the left PT. There were no significant differences in elasticity, velocity, and volumes when comparing location, age, or sex groups. No significant correlations were observed between the elasticity and velocity values and BMI. In conclusion, this preliminary work can be used as a reference for the diagnosis of PT diseases. Future comprehensive studies are necessary to establish the role of elastography in the diagnosis of pathologic tissue differentiation confirmed by clinical, laboratory, or pathology analyses. PMID- 30300324 TI - Ultrasound Assessment of Acute Kidney Injury. AB - Ultrasound assessment of the kidneys in patients with renal impairment has been described in various ways in the critical care, nephrology, and radiology literature, resulting in a somewhat heterogeneous picture of the gray-scale and Doppler ultrasound manifestation of acute kidney injury (AKI). Given that ultrasound assessment can potentially identify reversible causes of AKI or identify underlying chronic kidney disease, it is important for radiologists to be aware of the common etiologies of AKI and the spectrum of ultrasound findings. We review the definition and etiologies of renal injury and introduce the ultrasound SERVeillance framework-assessment of renal size, echogenicity, renal hilum, and vascularity-for the imaging assessment of AKI. PMID- 30300325 TI - Difference in Detection Rate of Portal Venous Gas via Computed Tomography and Ultrasonography in Pediatric Patients. AB - This study was performed to compare computed tomography (CT)- and ultrasonography (US)-derived detection rates of portal venous gas (PVG) in pediatric patients and investigate whether discrepancies between these modalities were influenced by patient age and interval between examinations. We included 25 children who underwent both CT and US within 2 days for evaluation of intestinal ischemia. McNemar test was used to compare the detection of PVG between the 2 modalities. The cohort was retrospectively divided into 2 groups based on whether comparable results were obtained via both modalities; the Mann-Whitney U test was used to compare patient age and interval between CT and US between these 2 groups. Among 25 children, CT and US yielded similar results in 17 patients regarding the presence or absence of PVG (median age/interval, 2 years [range, 0-17 years]/51 minutes [range, 2-1196 minutes]; 3/14 detected via both/not both modalities) and different results in 8 (median age/interval, 0 years [range, 0-15 years]/171.5 minutes [range, 64-1486 minutes]; 7/1 detected via US only/via CT only). There was a significant difference in PVG detection rate between US and CT (P = 0.034). Patient age did not differ significantly between the 2 groups (P = 0.206), but the interval between CT and US did (P = 0.025). In conclusion, the detection rate of PVG was higher with US, compared with CT, although the timings of the examinations could have influenced this finding. Ultrasonography could be useful for PVG detection in pediatric patients because it can be performed repeatedly at the bedside without radiation exposure. PMID- 30300326 TI - New primary immunodeficiency diseases: context and future. AB - PURPOSE OF REVIEW: Primary immunodeficiency diseases (PIDs) are genetic disorders classically characterized by impaired host defense and an increased susceptibility to infections. It is now appreciated that these conditions broadly include variations in the genetic code that cause dysregulated immune function. This review highlights the newly defined PIDs in the 2017 International Union of Immunologic Societies (IUIS) report, current approaches to diagnosing PIDs, and the implications for the future management of PIDs. RECENT FINDINGS: With the advances in and increased commercial availability of genetic testing and the adoption of the TREC assay into the US Newborn Screening program, the number of identified PIDs has exponentially risen in the past few decades, reaching over 350 disorders. The IUIS Inborn Errors of Immunity committee acknowledged at least 50 new disorders between 2015 and 2017. Furthermore, given the greater recognition of disorders with primarily immune dysregulation, the committee proposed a more inclusive term of 'inborn errors of immunity' to encompass primary immunodeficiencies and immune dysregulation disorders. SUMMARY: This latest IUIS report underscores the rapid expansion in the PID field with technologic advancements in immunogenetics and clinical screening discovering new genetic diseases, and therefore, paving the way to novel therapeutics and precision medicine. PMID- 30300327 TI - Female athletes: managing risk and maximizing benefit. AB - PURPOSE OF REVIEW: The purpose of this review is to provide an updated summary on the unique aspects of caring for female youth and adolescent athletes. RECENT FINDINGS: Recent research on female athletes has led to a better understanding of injuries and conditions that are more likely to occur in female youth and adolescent athletes, including the frequency and severity of concussions, musculoskeletal injury such as involving the anterior cruciate ligament, and the female athlete triad. Social factors, such as the growing pressure to specialize in a sport particularly at an early age, also put young female athletes at risk for issues such as overuse injuries. Researchers continue to explore the benefits of athletic participation that extend beyond physical fitness. SUMMARY: Female participation in youth sports has increased dramatically during the past 50 years. This has led to greater research on how to manage risks and maximize benefits for young female athletes, although there is still much to be learned. Providers should educate patients, parents, and coaches on both the increased risks for female athletes and ways to provide better support and accessibility of youth sports to all children. PMID- 30300328 TI - Advances in liver xenotransplantation. AB - PURPOSE OF REVIEW: This review highlights advances in liver xenotransplantation, focusing on immunologic barriers and mechanisms underlying graft failure and recipient demise, and discussion of recent in-vivo results. RECENT FINDINGS: Pig to primate models of liver xenotransplantation have been plagued by thrombocytopenia, anemia, and coagulopathy. It is now known that platelet sequestration is mediated by liver sinusoidal endothelial cells and Kupffer cells in part by asialoglycoprotein receptor 1-driven mechanisms. Xenoantigens, specifically N-glycolylneuraminic acid, play a role in graft injury as well as red blood cell consumption. Finally incompatibilities between coagulation cascade molecules contribute to lethal coagulopathy, but can be counteracted with genetic modifications and coagulation factor supplementation. Survival has markedly increased with this strategy. SUMMARY: An increased understanding of the cellular mechanisms responsible for failure of in-vivo pig to primate liver xenotransplant models has led to improved outcomes, and this recent success supports initial clinical application. PMID- 30300329 TI - Infections after xenotransplantation. AB - PURPOSE OF REVIEW: Xenotransplantation offers a solution for the global shortage of available organs. However, cross-species transplantation and immunosuppression raises concerns about transmission of zoonotic infections to the recipient as well as to the public. RECENT FINDINGS: Here, we review the major infections of concern after xenotransplantation, risks of their transmission, diagnostic, therapeutic as well as prevention modalities for these infections after xenotransplantation. This review is particularly timely in light of recent advances in porcine genome editing technology that allow removal of retroviral sequences. SUMMARY: We cannot appreciate the full risk of infections after xenotransplantation in absence of clinical trials. However, there are guidelines for strict microbiologic monitoring and reporting, infectious diagnostic assay development, breeding and quarantine of graft source animals to limit infectious transmission. PMID- 30300330 TI - Lung bioengineering: advances and challenges in lung decellularization and recellularization. AB - PURPOSE OF REVIEW: Bioengineering the lung based on its natural extracellular matrix (ECM) offers novel opportunities to overcome the shortage of donors, to reduce chronic allograft rejections, and to improve the median survival rate of transplanted patients. During the last decade, lung tissue engineering has advanced rapidly to combine scaffolds, cells, and biologically active molecules into functional tissues to restore or improve the lung's main function, gas exchange. This review will inspect the current progress in lung bioengineering using decellularized and recellularized lung scaffolds and highlight future challenges in the field. RECENT FINDINGS: Lung decellularization and recellularization protocols have provided researchers with tools to progress toward functional lung tissue engineering. However, there is continuous evolution and refinement particularly for optimization of lung recellularization. These further the possibility of developing a transplantable bioartificial lung. SUMMARY: Bioengineering the lung using recellularized scaffolds could offer a curative option for patients with end-stage organ failure but its accomplishment remains unclear in the short-term. However, the state-of-the-art of techniques described in this review will increase our knowledge of the lung ECM and of chemical and mechanical cues which drive cell repopulation to improve the advances in lung regeneration and lung tissue engineering. PMID- 30300331 TI - Mesenchymal stromal cell therapy in intestinal diseases. AB - PURPOSE OF REVIEW: The advent of cell therapies, mainly based on the use of mesenchymal stromal cells (MSCs), represents a great step forward in the treatment of immune-mediated conditions. Here, we focus on those intestinal disorders wherein MSCs have been applied for immunotherapeutic purposes and whose results are available. RECENT FINDINGS: By virtue of their ability to favour both tissue regeneration and immune tolerance, together with a substantial lack of immunogenicity, MSCs have gained huge attention in the last decade. Following abundant positive experimental data, a sizable number of clinical trials using MSCs as a new treatment in chronic inflammatory intestinal diseases were carried out with promising results and several are still ongoing. The main indication was refractory Crohn's disease wherein both feasibility and safety clearly emerged when treating the luminal phenotype with intravenous infusion/s, albeit no definitive conclusion on efficacy may be drawn. By contrast, the availability of robust demonstration also on the efficacy when treating the fistulizing phenotype through local injection/s of MSCs has led to approval of the marketing of an industrial preparation (darvadstrocel). SUMMARY: Successful clinical implementation of this attractive option is hampered by a number of obstacles arising from methodology and regulation issues, which require the institution of interdisciplinary task forces before this cell therapy becomes a bedside reality. PMID- 30300332 TI - Effects of COMT polymorphism on the cortical processing of vocal pitch regulation. AB - Recent evidence has shown that auditory-motor integration for speech production is influenced by cognitive functions such as working memory and attention, suggesting that speech motor control is likely modulated by mechanisms mediated by prefrontal regions. Catechol-O-methyltransferase (COMT) gene plays an important role in dopamine breakdown in the prefrontal cortex and has been associated with a variety of prefrontal cognitive functions. The present event related potential study investigated the association between COMT ValMet polymorphism and auditory-motor processing of vocal feedback errors. A sample of 131 Chinese young female adults was genotyped for rs4680 and produced sustained vowels while hearing their voice unexpectedly shifted down in pitch by 50 or 200 cents. The behavioral results showed no effects of COMT ValMet on vocal compensations for pitch perturbations. However, individuals with the Met allele produced significantly larger P2 responses to -200 cents perturbations than individuals with the Val/Val genotype. These results suggest the existence of a relationship between COMT ValMet polymorphism and self-monitoring of speech feedback errors, and they provide insights into our understanding of the top-down modulations of speech motor control mediated by prefrontal regions. PMID- 30300333 TI - The potential effect of human chorionic gonadotropin on vasoproliferative disorders of the immature retina. AB - Human chorionic gonadotropin (hCG) is known to be a powerful vascular endothelial growth factor (VEGF)-regulating hormone. It stimulates vascularization of the gravid uterus by upregulating VEGF expression. In the body, hCG activates the same receptor as luteinizing hormone (LH). Like hCG, LH is also strongly proangiogenic. Recently, it has been shown that LH/hCG receptors are present in the retina and that both LH and hCG are found in the eye. In fact, the human eye can synthesize its own hCG. We have previously shown that LH and VEGF are significantly correlated in mammalian eyes, potentially implicating LH receptor/hCG-receptor activation in intraocular VEGF regulation. Given that elevated VEGF is associated with progression of two vasoproliferative pediatric retinal disorders, retinopathy of prematurity and retinoblastoma, our objective was to determine whether hCG may potentially affect VEGF production and pathologic retinal vascularization in vasoproliferative disorders affecting the immature retina. In this study, we used (a) oxygen-induced retinopathy mouse model (standard model for retinopathy of prematurity) and (b) Y79 retinoblastoma cells (a human cell line derived from immature retinal cells). In the oxygen induced retinopathy model, number of preretinal nuclei (representing pathologic retinal neovascularization) significantly increases by 57% (P<0.05) in hCG treated mice. In Y79 cells, VEGF production significantly increases by 37% (P<0.05) in hCG-treated cells. These findings suggest that hCG is potentially able to influence retinal vascularization and VEGF production and thus, the hCG receptor may potentially represent a therapeutic target for vasoproliferative retinal disorders affecting the young eye.

PMID- 30300334 TI - EphA8 is a Prognostic Factor for Oral Tongue Squamous Cell Carcinoma. AB - BACKGROUND Oral tongue squamous cell carcinoma (OTSCC) is the most common malignancy of the oral cavity. Here we explore the potential effects of EphA8, which is one of the receptors in Ephs subfamily of RTKs (receptor tyrosine kinases), in the progression and prognosis of OTSCC. MATERIAL AND METHODS A total of 119 OTSCC patients were enrolled in this retrospective study. Immunohistochemistry (IHC) staining and quantitative polymerase chain reaction (Q PCR) were utilized to examine the expression of EphA8 in OTSSC tissues and adjacent non-tumor tissues. The relationship between EphA8 expression and the clinicopathological features of OTSCC patients were analyzed by chi-square. Survival analysis was carried out with Kaplan-Meier curve and the related log rank test. Multivariate analysis was then undertaken to assess the prognosis factor by utilizing the Cox proportional hazard regression model. In addition, MTT assay and Matrigel invasion assay were performed to examine the effects of EphA8 on the proliferation and invasion capacities of human oral squamous carcinoma cells (SCC-25) and human tongue squamous cell carcinoma cells (H357). RESULTS Q-PCR and IHC staining revealed that EphA8 was highly expressed in OTSCC tissues, especially in advanced stage OTSCC tissues. Kaplan-Meier curve showed that high EphA8 expression was significantly associated with poor prognosis, similar to age, smoking habit, drinking habit, tumor size, and TNM stage. Multivariate analysis indicated that EphA8 expression could serve as an independent prognostic factor in OTSCC. In vitro experiments revealed that overexpression of EphA8 might promote the progression of OTSCC via enhancing the invasion capacity but not proliferation capacity of tumor cells. CONCLUSIONS EphA8 was highly expressed in OTSCC tissues and was significantly associated with poor prognosis of OTSCC.

AB - Correctly ordering a sequence of speech sounds is a crucial aspect of speech production. Although studies have yielded a rich body of data on the neural substrates of visuomotor sequencing and sequence learning, research on brain regions and their functions involving speech sequence production hasn't attracted much attention until recently. Previous functional MRI studies manipulating the complexity of sequences at the phonemic, syllabic, and suprasyllabic levels have revealed a network of motor-related cortical and sub-cortical speech regions. In this study, we directly compared human brain activity measured with functional MRI during processing of a sequence of syllables compared with the same syllables processed individually. Among a network of regions independently identified as being part of the sensorimotor circuits for speech production, only the left posterior inferior frontal gyrus (pars opercularis, lIFG), the supplementary motor area (SMA), and the left inferior parietal lobe (lIPL) responded more during the production of syllable sequences compared to producing the same syllables articulated one at a time. PMID- 30300342 TI - Gene expression in response to optical defocus of opposite signs reveals bidirectional mechanism of visually guided eye growth. AB - Myopia (nearsightedness) is the most common eye disorder, which is rapidly becoming one of the leading causes of vision loss in several parts of the world because of a recent sharp increase in prevalence. Nearwork, which produces hyperopic optical defocus on the retina, has been implicated as one of the environmental risk factors causing myopia in humans. Experimental studies have shown that hyperopic defocus imposed by negative power lenses placed in front of the eye accelerates eye growth and causes myopia, whereas myopic defocus imposed by positive lenses slows eye growth and produces a compensatory hyperopic shift in refractive state. The balance between these two optical signals is thought to regulate refractive eye development; however, the ability of the retina to recognize the sign of optical defocus and the composition of molecular signaling pathways guiding emmetropization are the subjects of intense investigation and debate. We found that the retina can readily distinguish between imposed myopic and hyperopic defocus, and identified key signaling pathways underlying retinal response to the defocus of different signs. Comparison of retinal transcriptomes in common marmosets exposed to either myopic or hyperopic defocus for 10 days or 5 weeks revealed that the primate retina responds to defocus of different signs by activation or suppression of largely distinct pathways. We also found that 29 genes differentially expressed in the marmoset retina in response to imposed defocus are localized within human myopia quantitative trait loci (QTLs), suggesting functional overlap between genes differentially expressed in the marmoset retina upon exposure to optical defocus and genes causing myopia in humans. These findings identify retinal pathways involved in the development of myopia, as well as potential new strategies for its treatment. PMID- 30300343 TI - Physicochemical characterization and study of molar mass of industrial gelatins by AsFlFFF-UV/MALS and chemometric approach. AB - Industrial gelatins have different physicochemical properties that mainly depend of the raw materials origin and the extraction conditions. These properties are closely related to the molar mass distribution of these gelatins. Several methods exist to characterize molar mass distribution of polymer, including the Asymmetrical Flow Field Flow Fractionation method. The goal of this study is to analyze the relationship between physicochemical properties and the gelatins molar mass distribution obtained by Asymmetrical Flow Field Flow Fractionation. In this study, 49 gelatins samples extracted from pig skin are characterized in terms of gel strength and viscosity and their molar mass distribution are analyzed by Asymmetrical Flow Field Flow Fractionation coupled to an Ultraviolet and Multi Angle Light Scattering detector. This analytical method is an interesting tool for studying, simultaneously, the primary chains and the high molar-mass fraction corresponding to the polymer chains. Correlation analysis between molar mass distribution data from the different fractions highlights the importance of high molar mass polymer chains to explain the gel strength and viscosity of gelatins. These results are confirmed by an additional chemometric approach based on the UV absorbance of gelatin fractograms to predict gel strength (r2Cal = 0.85) and viscosity (r2Cal = 0.79). PMID- 30300345 TI - Climate communication for biologists: When a picture can tell a thousand words. AB - Pictures often tell a story better than the proverbial 1,000 words. However, in connection with climate change, many pictures can be highly misleading, for example, when a snowball is used to ridicule the notion of global warming or when a picture of a dead crop is supposed to alert people to climate change. We differentiate between such inappropriate pictures and those that can be used legitimately because they capture long-term trends. For example, photos of a glacier's retreat are legitimate indicators of the long-term mass balance loss that is observed for the vast majority of glaciers around the world. PMID- 30300346 TI - Confronting climate change in the age of denial. AB - This Editorial introduces a Collection of articles in which the authors explore the challenges and pitfalls of communicating the science of climate change in an atmosphere where evidence doesn't matter. PMID- 30300344 TI - Ran GTPase, an eukaryotic gene novelty, is involved in amphioxus mitosis. AB - Ran (ras-related nuclear protein) is a small GTPase belonging to the RAS superfamily that is specialized in nuclear trafficking. Through different accessory proteins, Ran plays key roles in several processes including nuclear import-export, mitotic progression and spindle assembly. Consequently, Ran dysfunction has been linked to several human pathologies. This work illustrates the high degree of amino acid conservation of Ran orthologues across evolution, reflected in its conserved role in nuclear trafficking. Moreover, we studied the evolutionary scenario of the pre-metazoan genetic linkage between Ran and Stx, and we hypothesized that chromosomal proximity of these two genes across metazoans could be related to a regulatory logic or a functional linkage. We studied, for the first time, Ran expression during amphioxus development and reported its presence in the neural vesicle, mouth, gill slits and gut corresponding to body regions involved in active cell division. PMID- 30300347 TI - A genome size and phylogenetic survey of Mediterranean Tripleurospermum and Matricaria (Anthemideae, Asteraceae). AB - The study of genome size variation can contribute valuable information on species relationships as well as correlate to several morphological or ecological features, among others. Here we provide an extensive report on genome sizes on genus Tripleurospermum and its closely related genus Matricaria, which are two typically Mediterranean genera particularly widespread and diverse in Turkey, the origin of most of the populations here studied. We analyse and discuss genome size variation in the first relatively complete molecular phylogenetic framework of Tripleurospermum (based on ITS and ETS ribosomal DNA-rDNA-regions). We find cases of intraspecific genome size variation, which could be taxonomically significant. Genome downsizing is also detected as the typical response to polyploidisation in Tripleurospermum taxa, being most conspicuous at the tetraploid level. Several positive correlations with genome size, including those with pollen and stomatal size or cypsela length, among others, are also found. Remarkably, taxa presenting rhizomes tend to present higher genome sizes, confirming a trend to accumulate nuclear DNA in such species, which could be explained by the nutrient reserves availability in their storage organs, allowing genome expansion, or by the lower rates of sexual reproduction in rhizomatous taxa. PMID- 30300348 TI - Association of plasma and urine viscosity with cardiometabolic risk factors and oxidative status. A pilot study in subjects with abdominal obesity. AB - There is increasing interest in the search for accurate, repeatable and widely applicable clinical biomarkers for the early detection of cardiometabolic alterations and oxidative status. Viscosity is a promising tool in that sense, although most studies have used simple viscosimeters, providing limited information, and have not considered oxidative status. The aim of this study was to assess whether viscosity determinations were associated with cardiometabolic and oxidative status in subjects at a primary stage of cardiometabolic risk. A pilot study (n = 20) was conducted in subjects with abdominal obesity, determining urine and plasma viscosity with a rotational rheometer at different shear rates (10000-1000 s-1 in plasma and 1000-50 s-1 in urine). Simple regression showed that urine viscosity was significantly (p< 0.05) associated with markers of oxidative status, and plasma viscosity with blood glucose. Categorical Principal Component Analysis plots showed that urine viscosity measurements at different shear rates clustered in three groups (low, intermediate and high shear rates) were selectively associated with uric acid, polyphenols and antioxidant capacity respectively. Plasma viscosity did not seem to be a relevant clinical marker in subjects with abdominal obesity. Therefore, urine viscosity could potentially serve as a complimentary marker in the evaluation of oxidative status. PMID- 30300350 TI - Tracking arctic marine mammal resilience in an era of rapid ecosystem alteration. AB - Global warming is significantly altering arctic marine ecosystems. Specifically, the precipitous loss of sea ice is creating a dichotomy between ice-dependent polar bears and pinnipeds that are losing habitat and some cetaceans that are gaining habitat. While final outcomes are hard to predict for the many and varied marine mammal populations that rely on arctic habitats, we suggest a simplified framework to assess status, based upon ranking a population's size, range, behavior, and health. This basic approach is proposed as a means to prioritize and expedite conservation and management efforts in an era of rapid ecosystem alteration. PMID- 30300349 TI - The effect of parasite infection on the recombination rate of the mosquito Aedes aegypti. AB - Sexual reproduction and meiotic recombination generate new genetic combinations and may thereby help an individual infected by a parasite to protect its offspring from being infected. While this idea is often used to understand the evolutionary forces underlying the maintenance of sex and recombination, it also suggests that infected individuals should increase plastically their rate of recombination. We tested the latter idea with the mosquito Aedes aegypti and asked whether females infected by the microsporidian Vavraia culicis were more likely to have recombinant offspring than uninfected females. To measure the rate of recombination over a chromosome we analysed combinations of microsatellites on chromosome 3 in infected and uninfected females, in the (uninfected) males they copulated with and in their offspring. As predicted, the infected females were more likely to have recombinant offspring than the uninfected ones. These results show the ability of a female to diversify her offspring in response to parasitic infection by plastically increasing her recombination rate. PMID- 30300352 TI - Contribution of social factors to maternal deaths in urban India: Use of care pathway and delay models. AB - This paper uses care pathway and delay models to better understand the possible social reasons for maternal deaths in a city with good public and private health infrastructure. The findings can inform programmes to reduce maternal mortality. During 2007-15, 136 maternal deaths were reported in Chandigarh, India. Using World Health Organisation's verbal autopsy questionnaire, interviews were conducted with primary caregivers of 68 (50%) of the 136 deceased women, as majority of the families had returned to their native places. We used process tracing techniques to construct the care pathways and identify delays, and explored open-ended responses using thematic analysis. The mean age of the deceased women was 27 years, 51% resided in slums, 32% were primigravida, 25% had their deliveries assisted by traditional birth attendants, and 23% had Caesarean section. Eight percent died at home, and 54% died in tertiary level facilities. Post-partum haemorrhage (26.5%), and complications of puerperium (25%) and labour/delivery (14.7%) were the reported medical causes. Male child preference and norms for home delivery were identified as the distal socio-cultural causes. Individual and family level factors included: shame on multiple pregnancies; fear of discrimination from providers; past successful deliveries at home leading to overconfidence and not seeking institutional care; and lack of awareness about family planning, antenatal care, and danger signs of pregnancy. Healthcare system factors were: non-availability of senior doctors at the time of consultation in the emergency that delayed initiation of immediate treatment, and lack of availability of life-saving equipment due to patient load. Empirical evidence was found on social causes of maternal deaths, which could have been prevented by appropriate actions at individual, family, societal, institutional and policy levels. This study identified potential preventable causes of primarily social origin, which could help in taking actionable steps at several levels to further reduce maternal deaths in India. PMID- 30300351 TI - Retention in HIV care during the 3 years following release from incarceration: A cohort study. AB - BACKGROUND: Sustained retention in HIV care (RIC) and viral suppression (VS) are central to US national HIV prevention strategies, but have not been comprehensively assessed in criminal justice (CJ) populations with known health disparities. The purpose of this study is to identify predictors of RIC and VS following release from prison or jail. METHODS AND FINDINGS: This is a retrospective cohort study of all adult people living with HIV (PLWH) incarcerated in Connecticut, US, during the period January 1, 2007, to December 31, 2011, and observed through December 31, 2014 (n = 1,094). Most cohort participants were unmarried (83.7%) men (77.0%) who were black or Hispanic (78.1%) and acquired HIV from injection drug use (72.6%). Prison-based pharmacy and custody databases were linked with community HIV surveillance monitoring and case management databases. Post-release RIC declined steadily over 3 years of follow-up (67.2% retained for year 1, 51.3% retained for years 1-2, and 42.5% retained for years 1-3). Compared with individuals who were not re-incarcerated, individuals who were re-incarcerated were more likely to meet RIC criteria (48% versus 34%; p < 0.001) but less likely to have VS (72% versus 81%; p = 0.048). Using multivariable logistic regression models (individual-level analysis for 1,001 individuals after excluding 93 deaths), both sustained RIC and VS at 3 years post-release were independently associated with older age (RIC: adjusted odds ratio [AOR] = 1.61, 95% CI = 1.22-2.12; VS: AOR = 1.37, 95% CI = 1.06-1.78), having health insurance (RIC: AOR = 2.15, 95% CI = 1.60-2.89; VS: AOR = 2.01, 95% CI = 1.53-2.64), and receiving an increased number of transitional case management visits. The same factors were significant when we assessed RIC and VS outcomes in each 6-month period using generalized estimating equations (for 1,094 individuals contributing 6,227 6-month periods prior to death or censoring). Additionally, receipt of antiretroviral therapy during incarceration (RIC: AOR = 1.33, 95% CI 1.07-1.65; VS: AOR = 1.91, 95% CI = 1.56-2.34), early linkage to care post-release (RIC: AOR = 2.64, 95% CI = 2.03-3.43; VS: AOR = 1.79; 95% CI = 1.45-2.21), and absolute time and proportion of follow-up time spent re incarcerated were highly correlated with better treatment outcomes. Limited data were available on changes over time in injection drug use or other substance use disorders, psychiatric disorders, or housing status. CONCLUSIONS: In a large cohort of CJ-involved PLWH with a 3-year post-release evaluation, RIC diminished significantly over time, but was associated with HIV care during incarceration, health insurance, case management services, and early linkage to care post release. While re-incarceration and conditional release provide opportunities to engage in care, reducing recidivism and supporting community-based RIC efforts are key to improving longitudinal treatment outcomes among CJ-involved PLWH. PMID- 30300353 TI - The placenta goes viral: Retroviruses control gene expression in pregnancy. AB - The co-option of endogenous retroviruses (ERVs) is increasingly recognized as a recurrent theme in placental biology, which has far-reaching implications for our understanding of mammalian evolution and reproductive health. Most research in this area has focused on ERV-derived proteins, which have been repeatedly co opted to promote cell-cell fusion and immune modulation in the placenta. ERVs also harbor regulatory sequences that can potentially control placental gene expression, but there has been limited evidence to support this role. In a recent study, Dunn-Fletcher and colleagues discover a striking example of an ERV-derived enhancer element that has been co-opted to regulate a gene important for human pregnancy. Using genomic and experimental approaches, they firmly establish that a primate-specific ERV functions as a placenta-specific enhancer for corticotropin-releasing hormone (CRH), a hormone linked to the control of birth timing in humans. Their findings implicate an extensive yet understudied role for retroviruses in shaping the evolution of placental gene regulatory networks.

While science plays a unique role in society, providing the best available evidence for policy choices, understanding the world, and informing citizens' daily lives, it does not hold any intrinsic advantage in creating captivating stories for mass audiences. Instead, science must compete with other storytellers, many of whom are not bound to scientific evidence. This presents a paradox-how can science preserve its credibility as curator of knowledge while engaging audiences with a communication format that is agnostic to truth? PMID- 30300355 TI - Strawberry seed extract and its major component, tiliroside, promote ceramide synthesis in the stratum corneum of human epidermal equivalents. AB - The activation of peroxisomeproliferator-activated receptor (PPAR) alpha can stimulate the expression of ceramide-related enzymes, and a major component of strawberry seed extract (SSE) tiliroside enhances the expression of PPARalpha. We determined whether SSE and tiliroside may stimulate ceramide synthesis in the stratum corneum (SC) of the human epidermal equivalents (HEEs) culture model. Treatment with SSE at 1.0 and 3.0 MUg/mL elicited a significant increase in the total ceramide content in the SC, which was accompanied by a significant increase in almost all ceramide species except for ceramide [EOS] and [AP]. Treatment with tiliroside at 0.3 MUg/mL slightly accentuated the total ceramide content in the SC together with a significant increase in the ceramide [NS, NDS] content. Messenger RNA analysis demonstrated that SSE at 1 or 3 MUg/mL significantly stimulated the gene expression of serine palmitoyltransferase (SPT) 2, ceramide synthase (CerS) 3, glucosylceramide synthase (GCS), and beta-glucocerebrosidase (GBA) but not of SPT1, sphingomyelin synthase (SMS) 1/2 and acid sphingomyelinase (ASM). In contrast, tiliroside elicited significant increases in the gene expression levels of GCS and GBA only at 0.3 and/or 0.1 MUg/mL. Western blotting analysis revealed that both SSE and tiliroside enhanced the protein expression levels of GCS and GBA but not of SPT2 at 1 or 3 and 0.1 or 0.3 MUg/mL, respectively. These findings suggested that both SSE and tiliroside have a distinct potential to stimulate the level of ceramide [NS, NDS] in the SC by enhancing the expression of GCS and GBA. The higher stimulatory effect with SSE than tiliroside on SC ceramide synthesis correlates with the significant increase observed with SSE but not tiliroside in the gene expression levels of SPT2 and CerS3. Therefore, it is anticipated that SSE is effective in improving skin barrier function and moisture retention in several ceramide-deficit skin conditions, including surfactant-induced roughened skin, xerosis, and atopic dermatitis. PMID- 30300356 TI - Human posterior parietal and dorsal premotor cortex encode the visual properties of an upcoming action. AB - Behavioral studies show that motor actions are planned by adapting motor programs to produce desired visual consequences. Does this mean that the brain plans these visual consequences independent of the motor actions required to obtain them? Here we addressed this question by investigating planning-related fMRI activity in human posterior parietal (PPC) and dorsal premotor (PMd) cortex. By manipulating visual movement of a virtual end-effector controlled via button presses we could dissociate motor actions from their sensory outcome. A clear representation of the visual consequences was visible in both PPC and PMd activity during early planning stages. Our findings suggest that in both PPC and PMd action plans are initially represented on the basis of the desired sensory outcomes while later activity shifts towards representing motor programs. PMID- 30300357 TI - Penetration and scattering-Two optical phenomena to consider when applying proximal remote sensing technologies to object classifications. AB - Proximal remote sensing is being used across a very wide range of research fields and by scientists, who are often without deep theoretical knowledge optical physics; the author of this article falls squarely in that category! This article highlights two optical phenomena, which may greatly influence the quality and robustness of proximal remote sensing: penetration and scattering. Penetration implies that acquired reflectance signals are associated with both physical and chemical properties of target objects from both the surface and internal tissues/structures. Scattering implies that reflectance signals acquired from one point or object are influenced by scattered radiometric energy from neighboring points or objects. Based on a series of laboratory experiments, penetration and scattering were discussed in the context of "robustness" (repeatability) of hyperspectral reflectance data. High robustness implies that it is possible to control imaging conditions and therefore: 1) obtain very similar radiometric signals from inert objects (objects that do not change) over time, and 2) be able to consistently distinguish objects that are otherwise highly similar in appearance (size, shape, and color) and in terms of biochemical composition. It was demonstrated that robustness of hyperspectral reflectance data (40 spectral bands from 385 to 1024 nm) were significantly influenced by penetration and scattering of radiometric energy. In addition, it was demonstrated that the influence of penetration and scattering varied across the examined spectrum. Characterization of how optical phenomena may affect the robustness of reflectance data is important when using proximal remote sensing technologies as tools used to classify engineering and biological objects. PMID- 30300358 TI - Adherence to etanercept therapy in rheumatoid arthritis patients during 3 years of follow-up. AB - OBJECTIVES: To determine the percentage non-adherence to etanercept in patients with rheumatoid arthritis during three years of follow-up. METHODS: During study visits in this prospective cohort study, blood samples were taken to determine serum etanercept concentrations using ELISA and patients were asked if they had missed an etanercept dose, at which date and for what reason. Non-adherence was defined as serum etanercept concentration <0.1 MUg/mL and no valid reason to miss the prescribed etanercept dose. RESULTS: In total, 292 consecutive patients treated with etanercept were included. Most patients had a valid reason to miss their etanercept dose (25/37). In total 12 out of 292 patients (4.1%, 95% confidence interval 2.2-7.2) were non-adherent during the 3 year period. In a small percentage of patients (3.4%, 95% confidence interval 0.8-10.4) who failed to respond to etanercept therapy, according to their rheumatologist, this was associated with inadequate exposure to etanercept and thus non-adherence. CONCLUSION: In this study, adherence to etanercept therapy was measured using serum etanercept concentration. In most patients an absent etanercept concentration was due to a medical reason. Furthermore, the majority of patients were adherent to etanercept therapy and had adequate drug exposure. In total, only 12 out of 292 patients (4.1%) were non-adherent during 3 years of follow-up. These findings highlight that only a small minority of patients are non-adherent to etanercept treatment, especially compared to adherence rates of other drugs. However, physicians should be aware that in patients failing to respond to treatment, non-adherence is a possible cause. PMID- 30300359 TI - Identification of Leptospira and Bartonella among rodents collected across a habitat disturbance gradient along the Inter-Oceanic Highway in the southern Amazon Basin of Peru. AB - BACKGROUND: The southern Amazon Basin in the Madre de Dios region of Peru has undergone rapid deforestation and habitat disruption, leading to an unknown zoonotic risk to the growing communities in the area. METHODOLOGY/PRINCIPAL FINDINGS: We surveyed the prevalence of rodent-borne Leptospira and Bartonella, as well as potential environmental sources of human exposure to Leptospira, in 4 communities along the Inter-Oceanic Highway in Madre de Dios. During the rainy and dry seasons of 2014-2015, we captured a total of 97 rodents representing 8 genera in areas that had experienced different degrees of habitat disturbance. Primarily by using 16S metagenomic sequencing, we found that most of the rodents (78%) tested positive for Bartonella, whereas 24% were positive for Leptospira; however, the patterns differed across seasons and the extent of habitat disruption. A high prevalence of Bartonella was identified in animals captured across both trapping seasons (72%-83%) and the relative abundance was correlated with increasing level of land disturbance. Leptospira-positive animals were more than twice as prevalent during the rainy season (37%) as during the dry season (14%). A seasonal fluctuation across the rainy, dry, and mid seasons was also apparent in environmental samples tested for Leptospira (range, 55%-89% of samples testing positive), and there was a high prevalence of this bacteria across all sites that were sampled in the communities. CONCLUSIONS/SIGNIFICANCE: These data indicate the need for increased awareness of rodent-borne disease and the potential for environmental spread along the communities in areas undergoing significant land-use change. PMID- 30300360 TI - Blood outgrowth endothelial cells (BOECs) as a novel tool for studying adhesion of Plasmodium falciparum-infected erythrocytes. AB - The lack of suitable animal models for the study of cytoadhesion of P. falciparum infected erythrocytes (IEs) has necessitated in vitro studies employing a range of cell lines of either human tumour origin (e.g., BeWo and C32 cells) or non human origin (e.g., CHO cells). Of the human cells available, many were isolated from adults, or derived from a pool of donors (e.g., HBEC-5i). Here we demonstrate, for the first time, the successful isolation of blood outgrowth endothelial cells (BOECs) from frozen stabilates of peripheral blood mononuclear cells obtained from small-volume peripheral blood samples from paediatric malaria patients. BOECs are a sub-population of human endothelial cells, found within the peripheral blood. We demonstrate that these cells express receptors such as Intercellular Adhesion Molecule 1 (ICAM-1/CD54), Endothelial Protein C Receptor (EPCR/CD201), platelet/endothelial cell adhesion molecule 1 (PECAM-1/CD31), Thrombomodulin (CD141), and support adhesion of P. falciparum IEs. PMID- 30300361 TI - Measures matter: A scoping review of maternal and newborn indicators. AB - BACKGROUND: A variety of global-level monitoring initiatives have recommended indicators for tracking progress in maternal and newborn health. As a first step supporting the work of WHO's Mother and Newborn Information for Tracking Outcomes and Results (MoNITOR) Technical Advisory Group, we aimed to compile and synthesize recommended indicators in order to document the landscape of maternal and newborn measurement and monitoring. METHODS: We conducted a scoping review of indicators proposed by global multi-stakeholder groups to suggest next steps to further support maternal and newborn measurement and monitoring. Indicators pertaining to pregnancy, childbirth, and postpartum/postnatal and newborn care were extracted and included in the indicator compilation, together with key indicator metadata. We examined patterns and relationships across the compiled indicators. RESULTS: We identified 140 indicators linked to maternal and newborn health topics across the continuum of service provision. Fifty-five indicators relate to inputs and processes, 30 indicators relate to outputs, outcomes comprise 37 indicators in the database, and 18 impact indicators. A quarter of indicators proposed by global groups is either under development/discussion or is considered "aspirational", highlighting the currently evolving monitoring landscape. Although considerable efforts have been made to harmonize indicator recommendations, there are still relatively few indicators shared across key monitoring initiatives and some of those that are shared may have definitional variation. CONCLUSION: Rapid, wide-ranging work by a number of multi-stakeholder groups has resulted in a substantial number of indicators, many of which partially overlap and many are not supported with adequate documentation or guidance. The volume of indicators, coupled with the number of initiatives promoting different indicator lists, highlight the need for strengthened coordination and technical leadership to harmonize recommendations for improved measurement and monitoring of data related to maternal and newborn heath. PMID- 30300362 TI - An efficient dynamic ID-based remote user authentication scheme using self certified public keys for multi-server environments. AB - Recently, Li et al. proposed a novel smart card and dynamic ID-based remote user authentication scheme for multi-server environments. They claimed that their scheme can resist several types of attacks. However, through careful analysis, we find that Li et al.'s scheme is vulnerable to stolen smart card and off-line dictionary attacks, replay attacks, impersonation attacks and server spoofing attacks. By analyzing other similar schemes, we find that a certain type of dynamic ID-based multi-server authentication scheme in which only hash functions are used and whereby no registration center participates in the authentication and session key agreement phase faces difficulties in providing perfectly efficient and secure authentication. To compensate for these shortcomings, we propose a novel dynamic ID-based remote user authentication scheme for multi server environments based on pairing and self-certified public keys. Security and performance analyses show that the proposed scheme is secure against various attacks and has many excellent features. PMID- 30300363 TI - Intrinsic activation of the vitamin D antimicrobial pathway by M. leprae infection is inhibited by type I IFN. AB - Following infection, virulent mycobacteria persist and grow within the macrophage, suggesting that the intrinsic activation of an innate antimicrobial response is subverted by the intracellular pathogen. For Mycobacterium leprae, the intracellular bacterium that causes leprosy, the addition of exogenous innate or adaptive immune ligands to the infected monocytes/macrophages was required to detect a vitamin D-dependent antimicrobial activity. We investigated whether there is an intrinsic immune response to M. leprae in macrophages that is inhibited by the pathogen. Upon infection of monocytes with M. leprae, there was no upregulation of CYP27B1 nor its enzymatic activity converting the inactive prohormone form of vitamin D (25-hydroxyvitamin D) to the bioactive form (1,25alpha-dihydroxyvitamin D). Given that M. leprae-induced type I interferon (IFN) inhibited monocyte activation, we blocked the type I IFN receptor (IFNAR), revealing the intrinsic capacity of monocytes to recognize M. leprae and upregulate CYP27B1. Consistent with these in vitro studies, an inverse relationship between expression of CYP27B1 vs. type I IFN downstream gene OAS1 was detected in leprosy patient lesions, leading us to study cytokine-derived macrophages (MPhi) to model cellular responses at the site of disease. Infection of IL-15-derived MPhi, similar to MPhi in lesions from the self-limited form of leprosy, with M. leprae did not inhibit induction of the vitamin D antimicrobial pathway. In contrast, infection of IL-10-derived MPhi, similar to MPhi in lesions from patients with the progressive form of leprosy, resulted in induction of type I IFN and suppression of the vitamin D directed pathway. Importantly, blockade of the type I IFN response in infected IL-10 MPhi decreased M. leprae viability. These results indicate that M. leprae evades the intrinsic capacity of human monocytes/MPhi to activate the vitamin D-mediated antimicrobial pathway via the induction of type I IFN. PMID- 30300364 TI - Safety of intrauterine devices in MRI. AB - OBJECTIVES: The paucity of safety information on intrauterine devices (IUD) for magnetic resonance imaging (MRI) examinations is clinically relevant. The aim of this study is to evaluate the MRI safety of clinically used IUDs composed of copper/gold and stainless steel at 1.5T and 3.0T. MATERIALS AND METHODS: We assessed and compared the displacement force, torque effects, presence of imaging artifacts and heating of IUDs composed of copper/gold (western IUDs) and stainless steel (China) on 1.5 and 3.0T MRI systems. RESULTS: Gold/Copper IUDs can show small deflection angles of 7 degrees +/- 7 degrees in the worst-case field gradient of 40T/m (equivalent to magnetic force of 0.5 mN), while the stainless steel IUD experienced significant magnetic force and deflection (Force > 7.5 N; deflection angle 90 degrees +/- 1 degrees ). Manual rotation and suspension method show no torque effects on gold/copper IUDs but high torque effects were observed by manual rotation on the stainless steel IUD. Heating measurements showed a temperature increase (rescaled to a wbSAR of 4 W/kg) of 1.4 degrees C at 1.5T / 3.4 degrees C at 3.0 T (stainless steel IUD), 3.2 degrees C at 1.5 T / 3.8 degrees C at 3 T (copper/gold IUD), 3.3 degrees C at 1.5 T / 4.8 degrees C at 3 T (copper 1), 3.8 degrees C at 1.5 T / 4.8 degrees C at 3 T (copper 2). The visible imaging artifacts of the copper and gold IUDs at 3 T MRI reach a diameter of 4 mm +/- 1 mm, while the stainless steel IUD resulted in artifacts measuring 200mm +/- 10 mm when using gradient echo pulse sequences. CONCLUSIONS: Standard IUDs (copper/gold) can be considered as conditional for MR safety at 1.5 T and 3.0 T, demonstrating at wbSAR up to 4W/kg and a magnetic field gradient of up to 40T/m with minimal imaging artifacts. The stainless steel IUD, however, induces unacceptable artifacts and is potentially harmful to patients during MRI due to high magnetic dislocation forces and torque (MR unsafe). PMID- 30300365 TI - The degree of altriciality and performance in a cognitive task show correlated evolution. AB - Previous comparative research on the evolution of cognition has tested what we call the "altricial intelligence hypothesis". This posits that a relationship between evolutionary changes in the altricial period length and cognition exists across animal species. However, the evidence available thus far either comes from indirect measurements of cognition or has not been conclusive. We performed a phylogenetic analysis of published data from various sources on 31 homeothermic species to test for an evolutionary association between the degree of altriciality and a direct measure of self-control. For each species, the degree of altriciality was determined based on the residual altricial period (i.e., the time from birth to fledging in birds and to weaning in mammals) on lifespan. The percentage of success in the cylinder task was the measure of self-control. Our results showed that the degree of altriciality covaried positively with the measure of self-control. Based on the results of this study, we sustain that evolutionary changes in the length of the altricial period are associated with evolutionary changes in the cognitive system used by homeotherms to perform the cylinder task. PMID- 30300366 TI - Killed Propionibacterium acnes enhances immunogenicity and tumor growth control of a dendritic-tumor cell hybrid vaccine in a murine melanoma model. AB - Hybrid vaccines have been investigated in clinical and experimental studies once expresses total antigens of a tumor cell combined with the ability of a dendritic cell (DC) to stimulate immune responses. However, the response triggered by these vaccines is often weak, requiring the use of adjuvants to increase vaccine immunogenicity. Killed Propionibacterium acnes (P. acnes) exerts immunomodulatory effects by increasing the phagocytic and tumoricidal activities of macrophages, promoting DC maturation, inducing pro-inflammatory cytokines production and increasing the humoral response to different antigens. Here, we evaluated the effect of P. acnes on a specific antitumor immune response elicited by a hybrid vaccine in a mouse melanoma model. Hybrid vaccine associated with P. acnes increased the absolute number of memory T cells, the IFN-gamma secretion by these cells and the IgG-specific titers to B16F10 antigens, polarizing the immune response to a T helper 1 pattern. Furthermore, the addition of P. acnes to a hybrid vaccine increased the cytotoxic activity of splenocytes toward B16F10 in vitro and avoided late tumor progression in a pulmonary colonization model. These results revealed the adjuvant effect of a killed P. acnes suspension, as it improved specific humoral and cellular immune responses elicited by DC-tumor cell hybrid vaccines. PMID- 30300367 TI - The effect of 3-month finasteride challenge on biomarkers for predicting cancer outcome on biopsy: Results of a randomized trial. AB - BACKGROUND: Finasteride, a 5-alpha reductase inhibitor may have effects on biomarkers such as prostate-specific antigen (PSA) that could be leveraged to improve screening. OBJECTIVE: To determine the predictive characteristics of biomarkers for prostate cancer for cancer on biopsy following 3 months of finasteride use compared with placebo. DESIGN, SETTING AND PARTICIPANTS: 383 men from multiple clinical sites with intermediate prostate cancer risk, without history of prostate cancer, were randomly allocated in a double-blinded manner, 4:1, to receive either finasteride or placebo for 90 days at which time a prostate biopsy was performed. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcomes were associations of biomarkers with prostate cancer that were tested using multiple logistic regression and area under the receiver operating curves (AUC). Biomarkers for PCA risk (PCA3, TMPRSS2:ERG (T2:ERG) gene product, and PSA) were measured at baseline and at biopsy in a blinded fashion to assess the predictive performance of baseline levels, 90-day levels, and measures of change relative to standard predictors. RESULTS AND LIMITATIONS: A total of 292 (233 finasteride; 59 placebo) randomized patients underwent biopsy and were analyzed. On finasteride, baseline and 90-day measures of PCA3 and T2:ERG had similar moderate discrimination capacity with AUCs 62 to 65% (p-values < 0.001 and 0.001, respectively), but their rates of change had no discrimination ability (AUC 51%, (95% CI 43 to 60% p = 0.72) and 48% (95% CI 44 to 60%, p = 0.62), respectively).) Relative to baseline, the 90-day PCA3 and PSA decreased in the finasteride group by 25% and 50%, respectively (both p<0.001). T2:ERG had a smaller, non-significant change post finasteride treatment (p = 0.08). CONCLUSIONS: Short-term finasteride therapy did not improve performance of the most commonly-employed prostate cancer biomarkers. Threshold values for new biomarkers of prostate cancer should be interpreted with caution in patients receiving finasteride until formal validation of test performance in these patients is conducted. PATIENT SUMMARY: Three months of finasteride treatment did not increase the accuracy for predicting the outcome on prostate biopsy but did have a significant effect on biomarker values. Adjustments to thresholds for biopsy for men on finasteride are proposed. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01296672. PMID- 30300368 TI - The crowding-out effect of tobacco expenditure on household spending patterns in Bangladesh. AB - BACKGROUND: Tobacco consumption constitutes a sizable portion of household consumption expenditure, which can lead to reduced expenditures on other basic commodities. This is known as the crowding-out effect. This study analyzes the crowding-out effect of tobacco consumption in Bangladesh, and the research findings have relevance for strengthening the tobacco control for improving health and well-being. METHODS: We analyzed data from the Bangladesh Household Income and Expenditure Survey 2010 to examine the differences in consumption expenditure pattern between tobacco user and non-user households. We further categorize tobacco user households in three mutually exclusive groups of smoking only, smokeless-only, and dual (both smoking and smokeless); and investigated the crowding-out effects for these subgroups. We compared the mean expenditure shares of different types of households, and then estimated the conditional Engel curves for various expenditure categories using Seemingly Unrelated Regression (SUR) method. Crowding-out was considered to have occurred if estimated coefficient of the tobacco use indicator was negative and statistically significant. RESULTS: We find that tobacco user households on average allocated less in clothing, housing, education, energy, and transportation and communication compared to tobacco non user households. The SUR estimates also confirmed crowding-out in these consumption categories. Mean expenditure share of food and medical expenditure of tobacco user households, however, are greater than those of tobacco non-user households. Albeit similar patterns observed for different tobacco user households, there were differences in magnitudes depending on the type of tobacco use, rural-urban locations and economic status. CONCLUSION: Policy measures that reduce tobacco use could reduce displacement of commodities by households with tobacco users, including those commodities that can contribute to human capital investments. PMID- 30300369 TI - Associations of lack of voluntary private insurance and out-of-pocket expenditures with health inequalities. Evidence from an international longitudinal survey in countries with universal health coverage. AB - OBJECTIVES: In countries with universal health coverage (UHC), national public health insurances cover 70% of health expenditures on average, but health care user fees and out-of-pocket expenditures have been neglected in empirical patient centered health inequality research. This study is the first to investigate how health care-related factors are associated with health status among middle-aged and elderly people-vulnerable groups for the burden of illness-in countries with UHC. DESIGN: Longitudinal observational cohort study. SETTING: Population-based cohort Survey of Health, Ageing and Retirement in Europe (SHARE) in twelve countries with UHC. PARTICIPANTS: Non-institutionalized people aged 50 and older (n = 29,260). Two subsamples were also used: participants without global activity limitation at baseline (n = 16,879) and participants without depression at baseline (n = 21,178). MAIN OUTCOME MEASURES: Risk of death, risk of global activity limitations, and risk of depression. We used mixed-effects Cox proportional hazards regressions to estimate hazard ratios (HR) for all-cause mortality, physical limitations, and depression. RESULTS: Having a voluntary private insurance to cover health expenses not included in the public health care system (44.1% of the total sample) was a protective factor for all outcomes (HR<=0.91), controlling for a large range of socio-economic variables. On the contrary, having out-of-pocket expenditures (62.4%) was a risk factor (HR>=1.12). CONCLUSIONS: UHC systems are not free from health inequalities: there is a potential effect of lack of voluntary private insurance and out-of-pocket expenditures on mortality and health. Health care-related factors should be at focus in future researches designed to understand and address health inequalities. Reducing out-of-pocket expenditures and developing voluntary private insurance may protect against premature illness and death. PMID- 30300370 TI - Enhancement of brackish water desalination using hybrid membrane distillation and reverse osmosis systems. AB - Desalination of geothermal brackish water by membrane distillation (MD) provides a low recovery rate, but integrating MD with reverse osmosis (RO) can maximize the production rate. In this study, different design configurations of a hybrid system involving brine recycling and cascading are studied via simulations, and the performance improvement due to the process integration is substantiated via the increased recovery rate and reduced specific energy consumption. Brine recycling is also found to improve the recovery rate considerably to 40% at an energy cost of 0.9 $/m3. However, this achievement is only valid when the final brine is recycled to the RO feed: when the final brine is recycled to the MD feed, the overall performance degrades because the recycled brine cools the feed and causes a serious reduction in the driving force and the consequent production rate. Configuring the hybrid system in multiple stages connected in series increases the recovery rate to 90% and reduces the specific energy consumption to 0.9 MJ/kg. Although the specific energy cost increases dramatically because external inter-stage heating is implemented, using a free energy source (such as a geothermal or waste-energy source) for inter-stage heating could provide the optimum configuration. PMID- 30300371 TI - Effectiveness of a multifactorial intervention for dizziness in older people in primary care: A cluster randomised controlled trial. AB - OBJECTIVES: Dizziness is common in older people. Physicians are often unable to identify a specific cause for dizziness in older people, even after an extensive diagnostic work-up. A prognosis-oriented approach, i.e. treating modifiable risk factors for an unfavourable course of dizziness, may reduce dizziness-related impairment in older people in primary care. DESIGN: Cluster randomized controlled trial. SETTING: 45 primary care practices in The Netherlands. PARTICIPANTS: 168 participants aged >=65y who consulted their general practitioner for dizziness and experienced significant dizziness-related impairment (Dizziness Handicap Inventory (DHI) >=30). Participants were part of to the intervention group (n = 83) or control group (n = 85), depending on whether they were enlisted in an intervention practice or in a control practice. INTERVENTIONS: The multifactorial intervention consisted of: medication adjustment in case of >=3 prescribed fall risk-increasing drugs (FRIDs) and/or stepped mental health care in case of anxiety disorder and/or depression and/or exercise therapy in case of impaired functional mobility. The intervention was compared to usual care. OUTCOME MEASURES: The primary outcome was dizziness-related impairment. Secondary outcomes were quality of life (QoL), dizziness frequency, fall frequency, anxiety and depression, use of FRIDs. RESULTS: Intention-to-treat analysis showed no significant intervention effect on dizziness-related impairment (DHI score difference -0.69 [95% CI -5.66;4.28]; p = 0.79). The intervention proved effective in reducing the number of FRIDs (FRID difference -0.48 [95% CI -0.89; 0.06]; p = 0.02). No significant intervention effects were found on other secondary outcomes. The uptake of and adherence to the interventions was significantly lower in patients eligible for >=2 interventions compared to patients eligible for one intervention (p<0.001). CONCLUSIONS: The multifactorial intervention for dizziness in older patients showed no significant intervention effect on most outcomes and adherence to the multifactorial intervention was low. Although multifactorial treatment for older dizzy people seems promising in theory, we question its feasibility in daily practice. Future research could focus on a sequential treatment for dizziness, e.g. measuring effectiveness of various evidence-based therapies in a stepwise approach. PMID- 30300372 TI - High variability phonetic training in adaptive adverse conditions is rapid, effective, and sustained. AB - This paper evaluates a novel high variability phonetic training paradigm that involves presenting spoken words in adverse conditions. The effectiveness, generalizability, and longevity of this high variability phonetic training in adverse conditions was evaluated using English phoneme contrasts in three experiments with Malaysian multilinguals. Adverse conditions were created by presenting spoken words against background multi-talker babble. In Experiment 1, the adverse condition level was set at a fixed level throughout the training and in Experiment 2 the adverse condition level was determined for each participant before training using an adaptive staircase procedure. To explore the effectiveness and sustainability of the training, phonemic discrimination ability was assessed before and immediately after training (Experiments 1 and 2) and 6 months after training (Experiment 3). Generalization of training was evaluated within and across phonemic contrasts using trained and untrained stimuli. Results revealed significant perceptual improvements after just three 20-minute training sessions and these improvements were maintained after 6 months. The training benefits also generalized from trained to untrained stimuli. Crucially, perceptual improvements were significantly larger when the adverse conditions were adapted before each training session than when it was set at a fixed level. As the training improvements observed here are markedly larger than those reported in the literature, this indicates that the individualized phonetic training regime in adaptive adverse conditions (HVPT-AAC) is highly effective at improving speech perception. PMID- 30300373 TI - Estimating recent HIV incidence among young men who have sex with men: Reinvigorating, validating and implementing Osmond's algorithm for behavioral imputation. AB - HIV incidence information is essential for epidemic monitoring and evaluating preventive interventions. However, reliable HIV incidence data is difficult to obtain, especially among marginalized populations, such as young men who have sex with men (YMSM). Here we evaluate the reliability of an alternative HIV incidence assessment method, behavioral imputation, as compared to serologically estimated HIV incidence. Recent HIV incidence among YMSM (aged 18 to 21 and 18 to 24 years) enrolled in a cohort study in Bangkok from 2006 to 2014 was estimated using two mid-point methods for seroconversion: 1) between age of first anal intercourse and first HIV-positive test (without previous HIV-negative test) (behavioral imputation) and 2) between the date of last negative and first positive HIV test (serological estimation). Serologically estimated HIV incidence was taken as the "gold standard" to evaluate between-method agreement. At baseline, 314 YMSM age 18 to 21 years accumulated 674 person-years (PY) of follow-up since first anal intercourse. Considering that 50 men had prevalent HIV infection, the behaviorally imputed HIV incidence was 7.4 per 100 PY. Of the remaining 264 HIV negative men, 54 seroconverted for HIV infection during the study, accumulating 724 PY of follow-up and a serologically estimated HIV incidence of 7.5 per 100 PY. At baseline, 712 YMSM age 18 to 24 years (including 18 to 21-year-old men analyzed above) accumulated 2143 PY of follow-up since first anal intercourse. Considering that 151 men had prevalent HIV infection, the behaviorally imputed HIV incidence was 7.0 per 100 PY. Of the remaining 561 HIV-negative men, 125 seroconverted for HIV infection during the study, accumulating 1700 PY of follow up and a serologically estimated HIV incidence of 7.4 per 100 PY. Behavioral imputation and serological estimation are in good agreement when estimating recent HIV incidence in YMSM.

AB - Recent studies have shown that HDAC inhibitors act synergistically with camptothecin derivatives in combination therapies. To exploit this synergy, new hybrid molecules targeting simultaneously topoisomerase I and HDAC were designed. In particular, a selected multivalent agent containing a camptothecin and a SAHA like template showed a broad spectrum of antiproliferative activity, with IC50 values in the nanomolar range. Preliminary in vivo results indicated a strong antitumor activity on human mesothelioma primary cell line MM473 orthotopically xenografted in CD-1 nude mice and very high tolerability.

AB - A Recommender System (RS) is an intelligent system that assists users in finding the items of their interest (e.g. books, movies, music) by preventing them to go through huge piles of data available online. In an effort to overcome the data sparsity issue in recommender systems, this research incorporates a content based filtering technique with fuzzy inference system and a conformal prediction approach introducing a new framework called Hybrid Content based Fuzzy Conformal Recommender System (HCF-CRS). The proposed framework is implemented to be used in the domain of movies and it provides quality recommendations to users with a confidence level and an improved accuracy. In our proposed framework, first, a Content Based Filtering (CBF) technique is applied to create a user profile by considering the history of each user. CBF is useful in the situations like: lack of demographic information and the data sparsity problems. Second, a Fuzzy based technique is incorporated to find the similarities and differences between the user profile and the movies in the dataset using a set of fuzzy rules to get a predicted rating for each movie. Third, a Conformal prediction algorithm is implemented to calculate the non-conformity measure between the predicted ratings produced by fuzzy system and the actual ratings from the dataset. A p-value (confidence measure) is computed to give a level of confidence to each recommended item and a bound is set on the confidence level called a significance level epsilon, according to which the movies only above the specified significance level are recommended to user. By building a confidence centric hybrid conformal recommender system using the content based filtering approach with fuzzy logic and conformal prediction algorithm, the reliability and the accuracy of the system is considerably enhanced. The experiments are evaluated on MovieLens and Movie Tweetings datasets for recommending movies to the users and they are compared with other state-of-the-art recommender systems. Finally, the results confirm that the proposed algorithms perform better than the traditional ones. PMID- 30300375 TI - High prevalence of spa type t571 among methicillin-susceptible Staphylococcus aureus from bacteremic patients in a French University Hospital. AB - Staphylococcus aureus bacteremia is one of the most frequent severe bacterial infections worldwide, with an associated mortality of about 20-40% in developed countries. In 2013, we noted an increase in this infection in the teaching hospital in Grenoble, France, compared to 2012. The mean incidence of S. aureus bacteremia was 0.28 per 1,000 patient-days in 2012 and 0.35 per 1,000 patient days in 2013. This trend was confirmed in 2014 (0.35 per 1,000 patient-days). In the present work we aimed to study the population of patients presenting with S. aureus bacteremia in 2013 and to genotype the corresponding S. aureus strains in order to identify a successful and/or virulent genotype to design a specific infection control program. One hundred ninety-one S. aureus isolates (including 9 methicillin-resistant) out of 199 corresponding cases of bacteremia were characterized with the spa typing method. Among 108 spa types, t571, t002, t008 and t084 were the most prevalent. Although not widely prevalent, t571 was the most frequently identified clone (8.4% of all isolates). Spa type t571 has been described in previous studies as belonging to the clonal complex CC398, which is consistent with the recent emergence of methicillin-susceptible S. aureus CC398 reported in blood cultures in Europe. PMID- 30300377 TI - Surgical resection for rectal cancer. Is laparoscopic surgery as successful as open approach? A systematic review with meta-analysis. AB - BACKGROUND: Recently, it has been questioned if minimally invasive surgery for rectal cancer was surgically successful. We decided to perform a meta-analysis to determine if minimally invasive surgery is adequate to obtain a complete resection for curable rectal cancer. METHODS: A systematic search pertaining to evaluation between laparoscopic and open rectal resection for rectal cancer was performed until 30th November 2016 in the electronic databases (PubMed, Web of Science, Scopus, EMBASE), using the following search terms in all possible combinations: rectal cancer, laparoscopy, minimally invasive and open surgery. Outcomes analyzed were number of clear Distal Resection Margins (DRM or DM), complete Circumferential Resection Margins (CRM) and complete, nearly complete and incomplete Total Mesorectal Excision (TME) and of patients who received laparoscopic or open treatment for rectal cancer. RESULTS: 12 articles were included in the final analysis. The prevalence of successful surgical resection was similar between open and laparoscopic surgery. About distance from distal margin of the specimen, clear CRM and complete TME there were no statistically significant difference between the two groups (MD = -0.090 cm, p = 0.364, 95% CI 0.283, 0.104; OR = 1.032, p = 0.821, 95% CI 0.784, 1.360; OR = 0.933, p = 0.720, 95% CI 0.638, 1.364, respectively). The analysis of nearly complete TME showed a significant difference between the two groups (OR = 1.407, p = 0.006, 95% CI 1.103, 1.795), while the analysis of incomplete TME showed a non-significant difference (OR = 1.010, p = 0.964, 95% CI 0.664, 1.534). CONCLUSIONS: By pooling together data from 5 RCTs and 7 nRCTs, we are able to provide evidence of safety and efficacy of minimally invasive surgery. Waiting for further randomized clinical trials, our results are encouraging to introduce laparoscopic rectal resection in daily practice. PMID- 30300378 TI - Influence of mirror therapy and motor imagery on intermanual transfer effects in upper-limb prosthesis training of healthy participants: A randomized pre-posttest study. AB - The effect that a motor skill trained on one side can lead to improvement in the untrained side is called intermanual transfer. Intermanual transfer can help enhance upper limb prosthetic training. To determine the influence of mirror therapy and motor imagery on intermanual transfer in upper limb prosthesis training, a pseudo-randomized clinical trial, single blinded, with a pre-posttest design was used. Forty-seven able-bodied, right-handed participants were pseudo randomly assigned to two training groups and one control group. One training group undertook an intermanual transfer training program, using an upper-limb prosthetic simulator with added mirror therapy and motor imagery. The second training group completed only the intermanual transfer training program. The control group completed a sham training: a dummy training without using the prosthesis simulator. The program lasted five consecutive days. To determine the improvement in skill, a test was administered before, immediately after, and six days after the training program. Training used the "unaffected" arm; tests were performed with the "affected" arm, resembling the amputated limb. Movement time, the time from the beginning of the movement until completion of the task; hand opening, the duration of the maximum prosthetic hand opening; and grip-force control, the deviation from the required force during a tracking task. No intermanual transfer effects were found: neither the intermanual transfer training program, nor the additional mirror therapy and motor imagery affected prosthesis skills. A limitation of the study was that the training program was applied to able-bodied subjects instead of patients with an amputation. Contrary to previous studies, no intermanual transfer effects were found. Additional mirror therapy and motor imagery did not ameliorate intermanual transfer effects. PMID- 30300379 TI - Child sexual abuse in India: A systematic review. AB - OBJECTIVE: Child Sexual Abuse (CSA) is a pressing human right issue and public health concern. We conducted a systematic review of quantitative and qualitative studies published in the past decade on CSA in India to examine the distribution of the prevalence estimates for both genders, to improve understanding of the determinants and consequences of CSA and identify gaps in the current state of research. METHODS: For this systematic review, we searched electronic literature databases (PubMed, POPLINE, and PsycINFO) for articles published in English on Child Sexual Abuse in India between January 1, 2006 and January 1, 2016 using 55 search terms. Data were extracted from published articles only. FINDINGS: Fifty one studies met inclusion criteria for the review. The review indicates that prevalence rates of CSA is high among both boys and girls in India. Due to heterogeneity of study designs and lack of standardised assessments, reported prevalence estimates varied greatly among both genders in different studies. There is a need to conduct representative studies using a validated instrument to obtain valid epidemiological estimates. Commercial sex workers, men who have sex with men, and women with psychiatric disorders were at higher risks for sexual abuse during childhood. In addition, the synthesis of qualitative data across studies included in the review suggests that exposure and perpetration of CSA is a multifaceted phenomenon grounded in the interplay between individual, family, community, and societal factors. The review indicates poor physical, behavioural, social, and mental health outcomes of CSA in India. We conclude with a research agenda calling for quantitative and qualitative studies to explore the determinants and perpetration of child sexual abuse in India from an ecological lens. This research agenda may be necessary to inform the development of a culturally tailored primary prevention and treatment strategy for CSA victims in India. PMID- 30300380 TI - Maternal dissatisfaction with their children's body size in private schools in the Federal District, Brazil. AB - We investigated the prevalence of maternal dissatisfaction with their child's body size and its associated factors among mothers of first- to third-grade elementary school students in private schools in the Federal District, Brazil. This is a cross-sectional study with 548 mother-schoolchildren pairs. We measured children's weight and height, and collected their mother's sociodemographic data and Body Mass Index using an online questionnaire. We also verified maternal body dissatisfaction and maternal dissatisfaction with their child's body size using Shape Scales. Most mothers (50.5%) were dissatisfied with their child's body size. Mothers of boys (Adjusted OR = 2.85) were more likely to want a larger silhouette for their child, while mothers of girls (Adjusted OR = 3.18), overweight (Adjusted OR = 24.83) and obese (Adjusted OR = 189.86) children were more likely to want a thinner silhouette for their child. A positive correlation was observed between maternal dissatisfaction with their own body and maternal dissatisfaction with their children's body size (rs = 0.178). There was a high prevalence of maternal dissatisfaction with their child's body size, particularly among mothers of overweight and obese children. Additional studies should be conducted to better understand the influence of this dissatisfaction on maternal practices and attitudes related to their child's body, food consumption, and lifestyle. PMID- 30300381 TI - An integrative approach using real-world data to identify alternative therapeutic uses of existing drugs. AB - Different computational approaches are employed to efficiently identify novel repositioning possibilities utilizing different sources of information and algorithms. It is critical to propose high-valued candidate-repositioning possibilities before conducting lengthy in vivo validation studies that consume significant resources. Here we report a novel multi-methodological approach to identify opportunities for drug repositioning. We performed analyses of real world data (RWD) acquired from the United States Food and Drug Administration's Adverse Event Reporting System (FAERS) and the claims database maintained by the Japan Medical Data Center (JMDC). These analyses were followed by cross validation through bioinformatics analyses of gene expression data. Inverse associations revealed using disproportionality analysis (DPA) and sequence symmetry analysis (SSA) were used to detect potential drug-repositioning signals. To evaluate the validity of the approach, we conducted a feasibility study to identify marketed drugs with the potential for treating inflammatory bowel disease (IBD). Primary analyses of the FAERS and JMDC claims databases identified psycholeptics such as haloperidol, diazepam, and hydroxyzine as candidates that may improve the treatment of IBD. To further investigate the mechanistic relevance between hit compounds and disease pathology, we conducted bioinformatics analyses of the associations of the gene expression profiles of these compounds with disease. We identified common biological features among genes differentially expressed with or without compound treatment as well as disease-perturbation data available from open sources, which strengthened the mechanistic rationale of our initial findings. We further identified pathways such as cytokine signaling that are influenced by these drugs. These pathways are relevant to pathologies and can serve as alternative targets of therapy. Integrative analysis of RWD such as those available from adverse-event databases, claims databases, and transcriptome analyses represent an effective approach that adds value to efficiently identifying potential novel therapeutic opportunities. PMID- 30300383 TI - Early hematoma retraction in intracerebral hemorrhage is uncommon and does not predict outcome. AB - BACKGROUND: Clot retraction in intracerebral hemorrhage (ICH) has been described and postulated to be related to effective hemostasis and perihematoma edema (PHE) formation. The incidence and quantitative extent of hematoma retraction (HR) is unknown. Our aim was to determine the incidence of HR between baseline and time of admission. We also tested the hypothesis that patients with HR had higher PHE volume and good prognosis. METHODS: This was a retrospective single-centre study in which serial planimetric volume measurements of the total hematoma volume (parenchymal (IPH) and intraventricular (IVH)) and PHE were performed in ICH patients with baseline non-contrast computed tomography (CT) completed within 6 hours of onset and follow-up CT 24 (+/-12) hours from symptom onset. HR was defined as a decrease in volume of >3ml or >15%, and hematoma expansion (HE) as an increase of >6ml or >30%. All other patients were categorized as stable hematoma (HS). Good outcome was defined as modified Rankin Scale (mRS) 0-2 at 90 days. RESULTS: A total of 136 patients (mean age = 69.3+/-13.39 years, 58.1% male) were included. Median (interquartile range) baseline total hematoma volume was 14.96 (7.80, 31.88) ml. HR >3ml and >15% occurred in 6 (4.4%) and 8 (5.9%) patients, respectively. Neither definition of HR was associated with follow-up PHE (p>0.297) or good outcome (p>0.249). IVH was the only independent predictor of HR (p<0.0241). CONCLUSIONS: Early HR is rare and associated with IVH, but not with PHE or clinical outcome. There was no relationship between HR, PHE, and patient prognosis. Therefore, HR is unlikely to be a useful endpoint in clinical ICH studies. PMID- 30300382 TI - Carious status and supragingival plaque microbiota in hemodialysis patients. AB - OBJECTIVE: The aim of this study was to evaluate the carious status and the microbial profiles of supragingival plaque in patients with chronic kidney disease undergoing hemodialysis. METHODS: This study included 30 patients with chronic kidney disease undergoing hemodialysis as well as 30 control subjects. Dental examination was performed and the decayed-missing-filled-teeth was recorded. Supragingival plaque was taken and analyzed using 16S rRNA gene amplicon by Illumina MiSeq sequencing to detect microbial composition and community diversity and structure. RESULTS: The level of decayed-missing-filled teeth was higher in the hemodialysis group than that in the control group. Microbial analysis showed a decrease in alpha diversity and a increase in relative abundance and prevalence of many acidogenic and aciduric caries related species in the supragingival plaque samples of the hemodialysis patients, including Streptococcus mutans, Lactobacillus salivarius, Lactobacillus fermentum, Lactobacillus vaginalis, Scardovia wiggsiae F0424, and Actinomyces naeslundii. CONCLUSION: Our results suggested that the hemodialysis patients were more susceptible to caries. More attentions for caries prevention and treatment should be paid to improve their life quality, and even to reduce their cardiovascular events and survival. PMID- 30300384 TI - Bat rabies in Washington State: Temporal-spatial trends and risk factors for zoonotic transmission (2000-2017). AB - BACKGROUND: Rabies is a zoonotic viral disease that can affect all mammals. In the United States, the majority of human rabies cases are caused by bats, which are the only known reservoirs for rabies virus (RABV) in Washington State. We sought to characterize bat RABV epidemiology in Washington among bats submitted by the public for RABV testing. METHODS: We examined temporal and spatial trends in RABV positivity (% positive) for taxonomically identified bats submitted to diagnostic laboratories during 2006-2017. For a subset of Myotis species, we evaluated sensitivity and predictive value positive (PPV) of morphological identification keys, using mitochondrial markers (cytochrome b) as a reference. For bats tested during 2000-2016, we analyzed RABV positivity by circumstances of encounters with humans, cats, and dogs. RESULTS: During 2006-2017, RABV positivity for all bat species was 6.0% (176/2,928). Among species with >=100 submissions, RABV positivity was 2.0%-11.7% and highest among big brown bats (Eptesicus fuscus). An increasing trend in annual positivity was significant only for big brown bats (P = 0.02), and was circumstantially linked to a geographic cluster. Sensitivity and PPV of morphological identification keys was high for M. evotis but varied for M. lucifugus, M. californicus, M. yumanensis, and M. septentrionalis. A positive RABV result was significantly associated with nonsynanthropic species, abnormal behavior, abnormal hiding, injury, biting, found in a body of water, found alive, found outdoors, and caught by a dog. CONCLUSION: Monitoring passive RABV surveillance trends enables public health authorities to perform more accurate risk assessments. Differences in temporal and spatial trends in RABV positivity by bat species indicate the importance of collecting taxonomic data, although morphological identification can be unreliable for certain Myotis species. Current public health practices for RABV exposures should be maintained as RABV infection in bats can never be excluded without diagnostic testing. PMID- 30300385 TI - A type 2 diabetes disease module with a high collective influence for Cdk2 and PTPLAD1 is localized in endosomes. AB - Despite the identification of many susceptibility genes our knowledge of the underlying mechanisms responsible for complex disease remains limited. Here, we identified a type 2 diabetes disease module in endosomes, and validate it for functional relevance on selected nodes. Using hepatic Golgi/endosomes fractions, we established a proteome of insulin receptor-containing endosomes that allowed the study of physical protein interaction networks on a type 2 diabetes background. The resulting collated network is formed by 313 nodes and 1147 edges with a topology organized around a few major hubs with Cdk2 displaying the highest collective influence. Overall, 88% of the nodes are associated with the type 2 diabetes genetic risk, including 101 new candidates. The Type 2 diabetes module is enriched with cytoskeleton and luminal acidification-dependent processes that are shared with secretion-related mechanisms. We identified new signaling pathways driven by Cdk2 and PTPLAD1 whose expression affects the association of the insulin receptor with TUBA, TUBB, the actin component ACTB and the endosomal sorting markers Rab5c and Rab11a. Therefore, the interactome of internalized insulin receptors reveals the presence of a type 2 diabetes disease module enriched in new layers of feedback loops required for insulin signaling, clearance and islet biology. PMID- 30300386 TI - Ablation of nasal-associated lymphoid tissue does not affect focal ischemic brain injury in mice. AB - Stroke is a devastating disease with a strong inflammatory component. It has been shown that part of this response is mediated by IL17+ gammadeltaT cells. gammadeltaT cells constitute a lymphocyte population with innate features that mainly populates epithelial surfaces including skin, intestine, and airways. We have shown that in the context of stroke, T cells migrate from the small intestine to the meninges but whether they can migrate from other epithelial surfaces is still unknown. Because of its proximity, one possible source of stroke-associated IL17+ gammadeltaT cells could be the Nasal-Associated Lymphoid Tissue (NALT) from which T cells could migrate along olfactory nerve sheaths through the cribriform plate into the brain and/or meninges. In order to study the role of NALT as a source for immune cells and/or inflammatory mediators in the context of stroke, we analyzed the effect of NALT ablation on immune cell infiltration and infarct volume after stroke. Infarct volume analysis did not show any significant difference between sham and NALT-ablated animals. In addition, no significant differences were found in immune cell infiltration in the brain or meninges of stroke animals subjected to NALT or Sham-ablation surgery. In conclusion, NALT ablation does not affect ischemic brain damage or immune cell infiltration in the meninges or brain after stroke. PMID- 30300388 TI - African cassava whitefly, Bemisia tabaci, cassava colonization preferences and control implications. AB - Cassava is a staple food for people across sub-Saharan Africa. Over the last 20 years, there has been an increased frequency of outbreaks and crop damage in this region caused by the cassava-adapted Bemisia tabaci putative species. Little is known about when and why B. tabaci adults move and colonize new cassava crops, especially in farming systems that contain a mixture of cultivar types and plant ages. Here, we assessed experimentally whether the age and variety of cassava affected the density of B. tabaci. We also tested whether the age and variety of the source cassava field affected the variety preference of B. tabaci when they colonized new cassava plants. We placed uninfested potted "sentinel" plants of three cassava varieties (Nam 130, Nase 14, and Njule Red) in source fields containing one of two varieties (Nam 130 or Nase 14) and one of three age classes (young, medium, or old). After two weeks, the numbers of nymphs on the sentinel plants were used as a measure of colonization. Molecular identification revealed that the B. tabaci species was sub-Saharan Africa 1 (SSA1). We found a positive correlation between the density of nymphs on sentinel plants and the density of adults in the source field. The density of nymphs on the sentinels was not significantly related to the age of the source field. Bemisia tabaci adults did not preferentially colonize the sentinel plant of the same variety as the source field. There was a significant interactive effect, however, between the source and sentinel variety that may indicate variability in colonization. We conclude that managing cassava source fields to reduce B. tabaci abundance will be more effective than manipulating nearby varieties. We also suggest that planting a "whitefly sink" variety is unlikely to reduce B. tabaci SSA1 populations unless fields are managed to reduce B. tabaci densities using other integrative approaches. PMID- 30300387 TI - Molecular characterization of feline astrovirus in domestic cats from Northeast China. AB - Feline astrovirus (FeAstV) which belonged to the genus Mamastrovirus was first identified in the feces of kittens with diarrhea in the USA in 1981 by electron microscopy, and had been reported in many countries. Presently, there are no any reports of the circulation of FeAstV in mainland China. We performed this study to investigate the apparent prevalence and genetic variability of FeAstV infected in cats in mainland China for the first time. We tested fecal samples of 105 cats with diarrhea and 92 asymptomatic cats in five cities in northeast China by RT PCR targeting RNA-dependent RNA polymerase (RdRp) gene of FeAstV, and analyzed sequences variability and phylogenetic evolution based on the complete capsid gene of FeAstV strains obtained from positive samples. The overall prevalence of FeAstV was 23.4% (46/197) of which 38 were tested in cats with diarrhea (36.2%, 38/105) and 8 were in asymptomatic cats (8.7%, 8/92). Mixed infection with other enteroviruses including feline parvovirus (FPV), feline bocavirus (FBoV) and feline kobuvirus (FeKoV) was found in 38 FeAstV-positive samples. Phylogenetic analysis based on the complete capsid gene revealed all FeAstV strains were divided into two different groups with a 0.454+/-0.016 of mean amino acid genetic distance between two groups, suggesting that FeAstVs should be classified into two different genotype species. This study provided the first molecular evidence that FeAstV with considerable genetic diversity was circulating in northeast China, and analyzed genetic variability and classification of FeAstVs for the first time. PMID- 30300389 TI - Wound healing in wild male baboons: Estimating healing time from wound size. AB - Wound healing in animals is important to minimize the fitness costs of infection. Logically, a longer healing time is associated with higher risk of infection and higher energy loss. In wild mammals, wounds caused by aggressive intraspecific interactions can potentially have lethal repercussions. Clarifying wounding rate and healing time is therefore important for measuring the severity of the attacks. In addition, impact of secondary damage of wounds (e.g., accidental peeling off of scabs) on heeling time is unknown despite the risk of infection in wild mammals. In baboons, most male injuries have been reported to result from male to male fights. Here, we investigated the relationship between wound size and healing time in wild anubis baboons to clarify the healing cost of physical attacks including secondary damage of wounds. Observations were conducted daily between August 2016 and July 2017 in Kenya for seven adult male anubis baboons. The individual wound rate was one per month on average. In 16 cases, we were able to assess the number of days required for wound healing, and the median healing time was 13 d. Wound healing time was longer for larger wounds. When the scab was peeled off accidentally because of external factors, healing time became longer. One of the causes of scabs' peeling off was baboons' scab-picking behavior, and the behaviour was considered self-injurious behavior. However, its predicted healing cost might not be high. We concluded that wounds less than 800 mm2 (the largest observed in this study) in baboon males have little effect on survival. Our results suggest that lethal wounds by physical attacks rarely occur in male baboons, and that healing time and delay caused by secondary damages can be estimated by measuring wound area. PMID- 30300390 TI - Glyphosate affects the larval development of honey bees depending on the susceptibility of colonies. AB - As the main agricultural insect pollinator, the honey bee (Apis mellifera) is exposed to a number of agrochemicals, including glyphosate (GLY), the most widely used herbicide. Actually, GLY has been detected in honey and bee pollen baskets. However, its impact on the honey bee brood is poorly explored. Therefore, we assessed the effects of GLY on larval development under chronic exposure during in vitro rearing. Even though this procedure does not account for social compensatory mechanisms such as brood care by adult workers, it allows us to control the herbicide dose, homogenize nutrition and minimize environmental stress. Our results show that brood fed with food containing GLY traces (1.25-5.0 mg per litre of food) had a higher proportion of larvae with delayed moulting and reduced weight. Our assessment also indicates a non-monotonic dose-response and variability in the effects among colonies. Differences in genetic diversity could explain the variation in susceptibility to GLY. Accordingly, the transcription of immune/detoxifying genes in the guts of larvae exposed to GLY was variably regulated among the colonies studied. Consequently, under laboratory conditions, the response of honey bees to GLY indicates that it is a stressor that affects larval development depending on individual and colony susceptibility. PMID- 30300392 TI - Rates and predictors of recurrent work disability due to common mental health disorders in the United States. AB - CONTEXT: Despite the high prevalence of work disability due to common mental disorders (CMD), no information exists on the rates and predictors of recurrence in a United States population. OBJECTIVE: To estimate recurrent work disability statistics and evaluate factors associated with recurrence due to CMDs including adjustment, anxiety, bipolar, and depressive disorders. METHODS: Recurrent work disability statistics were calculated using a nationwide database of disability claims. For the CMDs, univariate and multiple variable analyses were used to examine demographic factors and comorbidities associated with the time to recurrence. RESULTS: Of the CMDs, cases with bipolar (n = 3,017) and depressive disorders (n = 20,058) had the highest recurrence densities, 98.7 and 70.9 per 1000 person-years, respectively. These rates were more than three times higher than recurrence rates for other chronic disorders (e.g., diabetes, asthma; n = 105,558) and non-chronic disorders (e.g., injury, acute illnesses; n = 153,786). Individuals with CMD were also more likely to have a subsequent disability distinct from their mental health condition. Risk factors for recurrent CMD disability included being younger, being an hourly employee, living in a geographic area with more college graduates, having more previous psychiatric visits, having a previous work leave, and the type of work industry. CONCLUSIONS: Results indicate that CMD patients may benefit from additional care and disability management both during and after their work absence to help prevent subsequent CMD and non-CMD related leaves. PMID- 30300391 TI - Effect of flow on targeting and penetration of angiopep-decorated nanoparticles in a microfluidic model blood-brain barrier. AB - The blood-brain barrier (BBB) limits transport of nanoparticles from the circulation to the brain parenchyma. Angiopep-2, a peptide which functions as a brain transport vector, can be coupled to nanoparticles in order to facilitate binding and internalization by brain endothelial cells (ECs), and subsequent BBB penetration. This multi-step process may be affected by blood flow over brain ECs, as flow influences endothelial cell phenotype as well as interactions of nanoparticles with ECs. In the present study a microfluidic BBB model was constructed to evaluate binding and internalization by brain ECs, as well as BBB penetration of Angiopep-2 coupled liposomes (Ang2-Liposomes) in static and flow conditions. Ang2 conjugation to liposomes markedly improved binding relative to unconjugated liposomes. Ang2-Liposomes bound and were internalized efficiently by brain endothelial cells after static incubation or with 1 dyne/cm2 of fluid shear stress (FSS), while binding was reduced at a FSS of 6 dyne/cm2. Penetration of the model microfluidic BBB by Ang2-Liposomes was higher at a FSS of 1 dyne/cm2 and 6 dyne/cm2 than with static incubation. Analysis of barrier function and control experiments for receptor-mediated penetration provided insight into the magnitude of transcellular versus paracellular transport at each tested FSS. Overall, the results demonstrate that flow impacted the binding and BBB penetration of Ang2-functionalized nanoparticles. This highlights the relevance of the local flow environment for in vitro modeling of the performance of nanoparticles functionalized with BBB penetrating ligands. PMID- 30300393 TI - Quantitative optical coherence tomography angiography biomarkers for neovascular age-related macular degeneration in remission. AB - PURPOSE: To characterize quantitative optical coherence tomography angiography (OCT-A) parameters in active neovascular age-related macular degeneration (nAMD) patients under treatment and remission nAMD patients. DESIGN: Retrospective, cross-sectional study. PARTICIPANTS: One hundred and four patients of whom 72 were in Group 1 (active nAMD) and 32 in Group 2 (remission nAMD) based on SD-OCT (Spectral Domain OCT) qualitative morphology. METHODS: This study was conducted at the Centre Ophtalmologique de l'Odeon between June 2016 and December 2017. Eyes were analyzed using SD-OCT and high-speed (100 000 A-scans/second) 1050-nm wavelength swept-source OCT-A. Speckle noise removal and choroidal neovascularization (CNV) blood flow delineation were automatically performed. Quantitative parameters analyzed included blood flow area (Area), vessel density, fractal dimension (FD) and lacunarity. OCT-A image algorithms and graphical user interfaces were built as a unified tool in Matlab coding language. Generalized Additive Models were used to study the association between OCT-A parameters and nAMD remission on structural OCT. The models' performance was assessed by the Akaike Information Criterion (AIC), Brier Score and by the area under the receiver operating characteristic curve (AUC). A p value of <= 0.05 was considered as statistically significant. RESULTS: Area, vessel density and FD were different (p<0.001) in the two groups. Regarding the association with CNV activity, Area alone had the highest AUC (AUC = 0.85; 95%CI: 0.77-0.93) followed by FD (AUC = 0.80; 95%CI: 0.71-0.88). Again, Area obtained the best values followed by FD in the AIC and Brier Score evaluations. The multivariate model that included both these variables attained the best performance considering all assessment criteria. CONCLUSIONS: Blood flow characteristics on OCT-A may be associated with exudative signs on structural OCT. In the future, analyses of OCT A quantitative parameters could potentially help evaluate CNV activity status and to develop personalized treatment and follow-up cycles. PMID- 30300394 TI - Muscle regeneration is disrupted by cancer cachexia without loss of muscle stem cell potential. AB - Cancer cachexia is a severe, debilitating condition characterized by progressive body wasting associated with remarkable loss of skeletal muscle weight. It has been reported that cancer cachexia disturbs the regenerative ability of skeletal muscle, but the cellular mechanisms are still unknown. Here, we investigated the skeletal muscle regenerative process in mouse colon-26 (C26) tumor cell-bearing mice as a C26 cancer cachexia model. Although the proliferation and differentiation abilities of muscle stem cells derived from the C26 tumor cell bearing mice were sustained in vitro, the proliferation and differentiation were severely impaired in the cachexic mice. The numbers of both macrophages and mesenchymal progenitors, which are critical players in muscle regeneration, were reduced in the cancer cachexic mice, indicating that the skeletal muscle regeneration process was disrupted by cancer cachexia. Furthermore, the number of infiltrated neutrophils was also reduced in cancer cachexia mice 24 hours after muscle injury, and the expression of critical chemokines for muscle regeneration was reduced in cancer cachexia model mice compared to control mice. Collectively, although the ability to regeneration of MuSCs was retained, cancer cachexia disturbed skeletal muscle regenerative ability by inhibiting the orchestrated muscle regeneration processes.

AB - BACKGROUND: Direct-acting antivirals (DAA) have demonstrated high efficacy to achieve sustained virological response (SVR) in chronic hepatitis C patients. We aim to assess the change in health-related quality of life (HRQoL) among patients successfully treated, and to identify predictors of this variation. METHODS: In a prospective observational study, patients with chronic hepatitis C who started DAA therapy between May 2016 and April 2017 completed the EQ-5D-5L questionnaire at baseline and 12 weeks after the end of therapy before knowing the virological result. Analysis included all patients with SVR. RESULTS: Median baseline EQ-5D 5L scores of the 206 enrolled patients were 0.857 utility and 70.0 visual analogue scale (VAS). Following SVR, a reduction occurred in the proportion of patients with mobility problems (35% vs 24%, p = 0.012), pain/discomfort (60% vs 42%, p<0.001) and anxiety/depression (57% vs 44%, p = 0.012), with an increase in utility (+0.053, p<0.001) and VAS (+10, p<0.001). Score improvements were also observed in cirrhotic (+0.048 utility, p = 0.027; +15 VAS, p<0.001) and HIV co infected patients (+0.039 utility, p = 0.036; +5 VAS, p = 0.002). In multivariate analyses, middle age (45-64 years) and baseline anxiety/depression were associated to greater improvement in utility after SVR, and moderate-advanced liver fibrosis and cirrhosis to greater increase in VAS score. Low baseline values were associated to greater improvements in utility value and VAS score. CONCLUSIONS: The cure of chronic hepatitis C infection with DAA has a short term positive impact on HRQoL with improvement in mobility, pain/discomfort, anxiety/depression, utility value and VAS score. Patients with poor baseline HRQoL were the most beneficed. PMID- 30300396 TI - Malaria prevention practices and associated environmental risk factors in a rural community in Wakiso district, Uganda. AB - BACKGROUND: Besides use of insecticide-treated mosquito nets (ITNs) and indoor residual spraying (IRS), other complimentary measures including suitable housing structures, and environmental management that reduce breeding of malaria vectors, can be implemented at households to prevent the disease. However, most studies on malaria prevention have focused mainly on ITNs and IRS. The aim of this study was therefore to assess malaria prevention practices beyond ITNs and IRS, and associated environmental risk factors including housing structure in rural Wakiso district, Uganda. METHODS: A clustered cross-sectional survey was conducted among 727 households in Wakiso district. Data were collected using an interviewer administered questionnaire and observational checklist. The questionnaire assessed participants' household practices on malaria prevention, whereas the checklist recorded environmental risk factors for malaria transmission, and structural condition of houses. Poisson regression modeling was used to identify factors associated with use of mosquito nets by households. RESULTS: Of the 727 households, 471 (64.8%) owned at least one mosquito net. Use of mosquito nets by households was higher with increasing education level of participants-primary (aPR = 1.27 [95% CI: 1.00-1.60]), secondary (ordinary level) (aPR = 1.47 [95% CI: 1.16-1.85]) and advanced level / tertiary (aPR = 1.55 [95% CI: 1.19-2.01]), and higher household income (aPR = 1.09 [95% CI: 1.00-1.20]). Additionally, participants who were not employed were less likely to have mosquito nets used in their households (aPR = 0.83 [95% CI: 0.70-0.98]). Houses that had undergone IRS in the previous 12 months were 42 (5.8%), while 220 (43.2%) households closed their windows before 6.00 pm. Environmental risk factors found at households included presence of vessels that could potentially hold water for mosquito breeding 414 (56.9%), and stagnant water in compounds 144 (19.8%). Several structural deficiencies on houses that could promote entry of mosquitoes were found such as lack of screening in ventilators 645 (94.7%), and external doors not fitting perfectly into walls hence potential for mosquito entry 305 (42.0%). CONCLUSION: There is need to increase coverage and utilisation of ITNs and IRS for malaria prevention in Wakiso district, Uganda. In addition, other malaria prevention strategies such as environmental management, and improving structural condition of houses are required to strengthen existing malaria prevention approaches. PMID- 30300397 TI - The adoption of hypertension reference framework: An investigation among primary care physicians of Hong Kong. AB - BACKGROUND: The Hong Kong Government released a Reference Framework (RF-HT) for Hypertension Care for Adults in Primary Care Settings since 2010. No studies have evaluated its adoption by primary care physicians (PCPs) since its release. AIM: We aimed to evaluate the level of PCPs' adoption of the RF-HT and the potential barriers of its use in family practice. DESIGN AND SETTING: A cross-sectional study was conducted by a self-administered validated survey among all PCPs in Hong Kong through various means. METHODS: We assessed the level of and factors associated with its adoption by multivariate logistic regression modelling. RESULT: A total of 3,857 invitation episodes were sent to 2,297 PCPs in 2014 2015. We received 383 completed questionnaires. The average score of adoption was 3.43 out of 4.00, and 47.5% of PCPs highly adopted RF-HT in their daily consultations. Male practitioners (adjusted odds ratio [aOR] = 0.524, 95% CI = 0.290-0.948, p = 0.033) and PCPs of public sector (aOR = 0.524, 95% CI = 0.292 0.940, p = 0.030) were significantly less likely to adopt the RF-HT. PCPs with higher training completion or being academic fellow are more likely to adopt RF HT than those who were "nil to basic training completion" (aOR = 0.479, 95% CI = 0.269-0.853, p = 0.012) or "higher trainee" (aOR = 0.302, 95% CI = 0.093-0.979, p = 0.046). Three most-supported suggestions on RF-HT improvement were simplification of RF-HT, provision of pocket version and promoting in patients. CONCLUSION: Among PCP respondents, the adoption level of the RF-HT was high. These findings also highlighted some factors associated with its adoption that could inform targeted interventions for enhancing its use in clinical practice. PMID- 30300398 TI - Evaluation of antivirals against tick-borne encephalitis virus in organotypic brain slices of rat cerebellum. AB - Neurotropic tick borne encephalitis virus (TBEV) causes life-threatening disease, and accounts for most cases of tick-transmitted viral infections in Central and Eastern Europe and Russia. No specific treatment for TBEV infections exists, and vaccination is recommended for people at risk. So far, various nucleoside analogues have been investigated in vitro as potential candidates for treatment of TBEV infections. However, in vitro experiments with more complex cell culture systems, such as organotypic culture slices which model the sophisticated architecture of the target tissue are lacking. Using TBEV as a model, we investigated the suitability of rat organotypic cerebellum slices (OCS) to study the effectiveness of nucleoside analogues with a well-known anti-TBEV activity. In these OCS, 50 MUM of the nucleoside analogues 2'-C-methyladenosine (2'-CMA) and especially 7-deaza-2'-C-methyladenosine (7-deaza-2'-CMA) exhibited strong inhibitory effects on TBEV replication, reducing viral titers to an average of 103-fold and TBEV RNA content 60-90-fold. In contrast, the influence of 2'-C methylcytidine (2'-CMC) on TBEV replication was very weak, reducing virus titers by 10-fold and TBEV RNA content by 3-fold. In agreement with other studies, there was no noticeable difference in TBEV titers between OCS treated with 50 MUM of Ribavirin and the DMSO treated controls. All tested nucleoside analogues exhibited excellent cytotoxicity profiles at concentrations of 50 MUM. Our findings in OCS were highly comparable to data obtained in cell line culture systems. Therefore, OCS represent an ideal in vitro approach to study antivirals against TBEV and possibly other neurotropic viruses. PMID- 30300399 TI - MicroRNA-146a is induced by inflammatory stimuli in airway epithelial cells and augments the anti-inflammatory effects of glucocorticoids. AB - BACKGROUND: MicroRNAs (miRNAs) are emerging as central regulators of inflammation, but their role in asthma and airway epithelial cells is not well studied. Glucocorticoids are the cornerstone of therapy in asthma and other inflammatory disease, yet their mechanisms of action are not completely elucidated, and it is not clear whether miRNAs modulate their effects. OBJECTIVE: We aimed to identify miRNAs that regulate cytokine and chemokine expression in airway epithelial cells and whether these miRNAs are subject to the effects of glucocorticoids. METHODS AND RESULTS: MicroRNAomic analyses of immortalized, normal human bronchial epithelial cells identified 7 miRNAs that were altered by inflammatory cytokine treatment and 22 that were regulated by glucocorticoids (n = 3 for each treatment condition). MiR-146a emerged as a central candidate, whose expression was induced by TNF-alpha and repressed by glucocorticoids. Its role as a candidate in asthmatic inflammation was supported by expression profiling in human asthmatics, which showed that plasma miR-146a expression was elevated in asthma and associated with measures related to worse asthma outcomes, including elevated blood eosinophil counts, higher asthma control questionnaire scores, and need for higher doses of inhaled glucocorticoids. However, transfection of miR 146a in A549 cells treated with TNF-alpha +/- glucocorticoids produced an anti inflammatory effect and increased efficacy of glucocorticoids. CONCLUSIONS: We propose a model whereby miR-146a is induced by inflammatory conditions as a feedback mechanism to limit inflammation. Exogenous administration of miR-146a augmented the effects of glucocorticoids and could be a novel therapeutic strategy to enhance efficacy of these medications. PMID- 30300400 TI - Associations between diabetes mellitus and pulmonary hypertension in chronic respiratory disease patients. AB - BACKGROUND: Pulmonary hypertension (PH) is a common complication of chronic respiratory disease. Recent studies have reported diabetes mellitus (DM) to be a poor prognostic factor in patients with chronic respiratory disease, including chronic obstructive pulmonary disease or interstitial pneumoniae. However, the association between DM and PH in chronic respiratory disease remains unclear. In this study, we aimed to investigate whether DM is a predictor of PH in patients with chronic respiratory disease. METHODS: We prospectively analyzed 386 patients in our hospital with chronic respiratory disease. An echocardiographic pressure gradient between the right atrium and the right ventricle of >= 40 mmHg was defined as PH. We compared the clinical characteristics and impact of DM between chronic respiratory disease patients with and those without PH. RESULTS: Of the 386 patients, 42 (10.9%) were diagnosed as having PH. The PH group had higher modified medical research council (mMRC) grade and complication rate of DM, but not hypertension and hyperlipidemia, when compared to the non-PH group. Multivariable logistic regression analysis revealed that mMRC scale (odds ratio 1.702, 95% confidence interval, 1.297 to 2.232, P < 0.001) and presence of DM (odd ratio 2.935, 95% confidence interval, 1.505 to 5.725, P = 0.002) were associated with PH in chronic respiratory disease patients. CONCLUSION: DM is potentially associated with PH and is an independent factor for prediction of PH in patients with chronic respiratory disease. PMID- 30300401 TI - Association of tumour necrosis factor-alpha (TNF-alpha) gene polymorphisms (-308 G>A and -238 G>A) and the risk of severe dengue: A meta-analysis and trial sequential analysis. AB - Individual studies have assessed the association between TNF-alpha-308G>A and TNF alpha-238 G>A polymorphisms and severity of dengue infection. However, the results are inconclusive and most studies had small sample sizes. The objective of this study was to summarize the evidence of association between TNF-alpha-308 G>A and TNF-alpha-238 G>A and severity of dengue infection. This study follows the preferred reporting items for systematic reviews and meta- analyses of genetic association studies, recommended by PLOS One. We calculated pooled odds ratio and its 95% confidence interval (CI) to estimate the association between TNF-alpha-308 G>A or TNF-alpha-238 G>A and the risk of severe dengue infections. To determine the information size required for this meta-analysis study, a trial sequential analysis (TSA) was done. Eight studies (640 cases and 1275 controls), which assessed the association of TNF-alpha-308 G>A or TNF-alpha-238 G>A and the risk of DHF were included. Overall, we found no significant association between TNF-alpha-308 G>A and the DHF risk in the allelic model (OR, 0.91; 95% CI, 0.51 1.63), the recessive model (OR,1.32;95%CI,0.73-2.37), the dominant model (OR,0.93;95%CI:0.59-1.47) or the additive model (OR,1.43,95;95%CI:0.79-2.59). There was also no significant association between TNF-alpha-238 G>A and DHF risk under the allele contrast model (OR:1.51;95%CI:0.88-2.58), the recessive model (OR,1.48,95% CI:0.33-6.58), the dominant model (OR,1.48;95%CI:0.56-3.92), or the additive model (OR:1.5;95%CI:0.34-6.69). On subgroup analysis, neither the Asian population nor the non-Asian population showed significant association between TNF-alpha-308 G>A/TNF-alpha-238 G>A and the DHF risk under any genetic models. Leave-one-out meta-analysis showed stability of the results. TSA plots suggested that the sample size in this meta-analysis study was below the required information size. The findings suggest an inclusive evidence of the association between TNF-alpha-308/ TNF-alpha-238 G>A and the risk of developing severe dengue infection. Large studies with evidence of Hardy-Weinberg equilibrium, assessing gene-gene interactions are recommended. PMID- 30300402 TI - Association of monocyte myeloperoxidase with incident cardiovascular disease: The Atherosclerosis Risk in Communities Study. AB - Myeloperoxidase (MPO) is a heme-containing peroxidase found in azurophilic granules of neutrophils and monocytes. Epidemiological studies have reported greater plasma MPO concentration to be associated with increased incidence of several cardiovascular diseases (CVD), but the association of intracellular monocyte MPO (mMPO) with CVD is unclear. The prospective population-based Atherosclerosis Risk in Communities (ARIC) cohort study measured mMPO using flow cytometry in 1,465 participants. The association of mMPO with incident cardiovascular disease (CVD, comprising incident coronary heart disease (CHD), heart failure, stroke, peripheral artery disease, and cardiovascular mortality) was examined over a median 9.6 years of follow-up (n = 290 CVD events). There was no statistically significant association between mMPO and all incident CVD events in either age, sex, and race-adjusted proportional hazards models (HR (95% CI) across tertiles of mMPO: 1, 1.09 (0.76, 1.57), and 0.78 (0.52, 1.15), P-trend = 0.21) or adjusted for other major CVD risk factors (HR (95% CI): 1, 1.17 (0.81, 1.69), and 0.87 (0.58, 1.29), P-trend = 0.50). There also was no association between mMPO tertiles and incident CHD, heart failure, or all-cause mortality, examined separately. In conclusion, intracellular monocyte myeloperoxidase was not associated with incident cardiovascular disease in this prospective population-based study. PMID- 30300403 TI - High rates of death and loss to follow-up by 12 months of rifampicin resistant TB treatment in South Africa. AB - INTRODUCTION: Treatment success rates of rifampicin resistant (RR)/multi-drug resistant (MDR) tuberculosis (TB) in South Africa range from 43-48%, falling short of the World Health Organization's target of >=75%. We present rates and assess predictors of attrition by 12 months on treatment. METHODS: Prospective observational cohort analysis of adults (>=18 years) initiating RR/MDR-TB treatment from 01 March 2013 to 30 September 2016. Attrition was defined as a combination of death and loss to follow-up (LTFU; treatment interruption >=2 months) by 12 months on treatment. Predictors of attrition were identified using Cox Proportional Hazards models to estimate crude (HR) and adjusted hazard ratios (aHR) with corresponding 95% confidence intervals. RESULTS: By 12 months on treatment, 75/240 (31.3%) patients had either died (37/240; 15.4%) or been LTFU (38/240; 15.8%). Patients with moderate/severe anaemia (aHR: 2.10; 95% CI 1.00 4.39), and those who were smear positive at baseline (aHR: 2.04; 95% CI 1.01 4.12) were significantly more likely to die or be lost from care. CONCLUSION: At this outpatient DR-TB treatment site, there was a high rate of attrition halfway through the standard treatment course at 12 months of 31%. High rates of attrition by 12 months on treatment may continue during the second-half of therapy. PMID- 30300404 TI - Emotional responses to conspecific distress calls are modulated by affiliation in cockatiels (Nymphicus hollandicus). AB - Vocal communication is used across the animal kingdom to transfer information from emitters to receivers, such as size, sex, age, dominance status or even emotional states. The transmission of an emotional state from one individual to another is called "emotional contagion" and is classified as the first level of empathy. Emotional contagion is thought to be stronger between familiar individuals. While affiliation represents a stronger relation between individuals than mere familiarity, it remains understudied whether affiliation modulates emotional reactions as well. Using cockatiels (Nymphicus hollandicus), we played back three types of audio stimuli to individual birds: a partner's distress call (emitted when birds are caught or forcibly restrained), a non-partner's distress call, and a control sound (white noise). The calls were recorded from familiar birds with either low (non-partners) or high levels of affiliation (partners). The subjects' response was scored using four behavioural parameters: the time spent near the loudspeaker, the amount of movements, the number of calls emitted, and the position of the crest. Across all variables, birds were more attentive and active when confronted to distress calls compared to control sounds, particularly when the distress call was emitted from a partner rather than a non partner. These results raise the possibility that distress calls do not only function as a stimulus-triggering automatic reaction in cockatiels but also transmit emotions. Moreover, affiliation enhanced emotional reactions to conspecific distress calls. Our data provides first insights into the mechanisms of emotional contagion in parrots. PMID- 30300406 TI - BlasterJS: A novel interactive JavaScript visualisation component for BLAST alignment results. AB - BACKGROUND: The wide range of potential applications has made the Basic Local Alignment Search Tool (BLAST) a ubiquitous tool in the field of Molecular Biology. Within this context, it is increasingly appealing to embed BLAST services within larger Web applications. RESULTS: This work introduces BlasterJS viewer, a new JavaScript library for the lightweight development of Web-based applications supporting the visualisation of BLAST outputs. BlasterJS detaches from similar data viewers by focusing on the visual and interactive display of sequence similarity results and being completely independent of BLAST services. BlasterJS is compatible with the text outputs generated by the BLAST family of programs, namely BLASTp, BLASTn, BLASTx, tBLASTn, and tBLASTx, and works in all major Web browsers. Furthermore, BlasterJS is available through the EBI's BioJS registry 5, which extends its potential use to a wider scope of bioinformatics applications. CONCLUSIONS: BlasterJS is new Javascript library that enables easy and seamless integration of visual and interactive representations of BLAST outputs in Web-based applications supporting sequence similarity search. BlasterJS is free accessible at http://sing-group.org/blasterjs/. PMID- 30300405 TI - The long-term use of foot orthoses affects walking kinematics and kinetics of children with flexible flat feet: A randomized controlled trial. AB - BACKGROUND: Due to inconclusive evidence on the effects of foot orthoses treatment on lower limb kinematics and kinetics in children, studies are needed that particularly evaluate the long-term use of foot orthoses on lower limb alignment during walking. Thus, the main objective of this study was to evaluate the effects of long-term treatment with arch support foot orthoses versus a sham condition on lower extremity kinematics and kinetics during walking in children with flexible flat feet. METHODS: Thirty boys aged 8-12 years with flexible flat feet participated in this study. While the experimental group (n = 15) used medial arch support foot orthoses during everyday activities over a period of four months, the control group (n = 15) received flat 2-mm-thick insoles (i.e., sham condition) for the same time period. Before and after the intervention period, walking kinematics and ground reaction forces were collected. RESULTS: Significant group by time interactions were observed during walking at preferred gait speed for maximum ankle eversion, maximum ankle internal rotation angle, minimum knee abduction angle, maximum knee abduction angle, maximum knee external rotation angle, maximum knee internal rotation angle, maximum hip extension angle, and maximum hip external rotation angle in favor of the foot orthoses group. In addition, statistically significant group by time interactions were detected for maximum posterior, and vertical ground reaction forces in favor of the foot orthoses group. CONCLUSIONS: The long-term use of arch support foot orthoses proved to be feasible and effective in boys with flexible flat feet to improve lower limb alignment during walking. PMID- 30300407 TI - Outcomes of endovascular treatment versus bypass surgery for critical limb ischemia in patients with thromboangiitis obliterans. AB - We aimed to compare the clinical outcomes between endovascular treatment and inframalleolar bypass surgery for critical limb ischemia (CLI) in patients with thromboangiitis obliterans (TAO) and to assess the role of bypass surgery in the era of innovative endovascular treatment. Between January 2007 and December 2017, a total of 33 consecutive patients with the diagnosis of TAO presenting with CLI who underwent endovascular treatment (endovascular group, n = 22) or bypass surgery to the pedal or plantar vessels (bypass group, n = 11) were included and analyzed retrospectively. The primary endpoint was defined as a major amputation of the index limb, and the secondary endpoint was defined as graft occlusion, regardless of the number of subsequent procedures. In the bypass group, six patients (55%) had undergone previous failed endovascular procedures and/or arterial bypass surgery to the index limb before inframalleolar bypass, and two patients (18%) received microvascular flap reconstruction after bypass surgery. During the median follow-up period of 32 months (range 1-115 months), there were no significant differences in primary and secondary endpoints between the two groups although the bypass group had a higher Rutherford class than the endovascular group. Kaplan-Meier survival analysis showed that there were similar limb salvage (P = 0.95) and graft patency rates (P = 0.39). In conclusion, endovascular treatment is a valid strategy leading to an acceptable limb salvage rate for TAO patients, and surgical bypass to distal target vessels could play a vital role in cases of previous failed endovascular treatment or extensive soft tissue loss of the foot. PMID- 30300408 TI - Sepsis is associated with reduced spontaneous neutrophil migration velocity in human adults. AB - Sepsis is a common and deadly complication among trauma and surgical patients. Neutrophils must mobilize to the site of infection to initiate an immediate immune response. To quantify the velocity of spontaneous migrating blood neutrophils, we utilized novel microfluidic approaches on whole blood samples from septic and healthy individuals. A prospective study at a level 1 trauma and tertiary care center was performed with peripheral blood samples collected at <12 hours, 4 days, and/or 14 days relative to study initiation. Blood samples were also collected from healthy subjects. Ex vivo spontaneous neutrophil migration was measured on 2 MUl of whole blood using microfluidic devices and time-lapse imaging. For each sample, individual neutrophils were tracked to calculate mean instantaneous velocity. Forty blood samples were collected from 33 patients with sepsis, and 15 blood samples were collected from age- and gender-matched healthy, control subjects. Average age was 61 years for septic patients with a male predominance (67%). Overall, average spontaneous neutrophil migration velocity in septic samples was 16.9 MUm/min, significantly lower than controls samples at 21.1 MUm/min (p = 0.0135). Neutrophil velocity was reduced the greatest at <12 hours after sepsis (14.5 MUm/min). Regression analysis demonstrated a significant, positive correlation between neutrophil velocity and days after sepsis (p = 0.0059). There was no significant association between neutrophil velocity and age, gender, APACHE II score, SOFA score, sepsis severity, total white blood cell count, or percentage of neutrophils. Circulating levels of the cytokines IL-6, IL-8, IL-10, MCP-1, IP-10, and TNF were additionally measured using bead-based multiplex assay and found to peak at <12 hours and be significantly increased in patients with sepsis at all three time points (<12 hours, 4 days, and 14 days after sepsis) compared to healthy subjects. In conclusion, these findings may demonstrate an impaired ability of neutrophils to respond to sites of infection during the proinflammatory phase of sepsis. PMID- 30300409 TI - A mathematical model for predicting the adult height of girls with idiopathic central precocious puberty: A European validation. AB - BACKGROUND: A previous single-center study established a mathematical model for predicting the adult height (AH) in girls with idiopathic central precocious puberty (CPP). OBJECTIVE: To perform internal and external validations by comparing the actual AH to the calculated AH established by this model and to update it. METHODS: The original formula, calculated AH (cm) = 2.21 (height at initial evaluation, SD) + 2.32 (target height, SD) - 1.83 (luteinizing hormone/follicle-stimulating hormone peaks ratio) + 159.68, was established in a sample of 134 girls (group 4) and was applied to additional girls with CPP seen in the same center (group 1, n = 35), in Germany (group 2, n = 43) and in the Netherlands (group 3, n = 72). This formula has been updated based on these extended data, and both versions are available at the following location: http://www.kamick.org/lemaire/med/girls-cpp15.html. RESULTS: Despite the differences among the 4 groups in terms of their characteristics at the initial evaluation and the percentages of patients treated with the gonadotropin releasing hormone analogue, they have similar calculated and actual AHs. The actual AHs are 162.2+/-7.0, 163.0+/-7.6, 162.4+/-7.7 and 162.1+/-5.6 cm in groups 1 to 4, respectively. They are highly correlated with the AHs calculated by the formula established in the original group (group 4), with R at 0.84, 0.67 and 0.69 in groups 1 to 3, respectively. When the actual AHs and the AHs predicted by the Bayley and Pinneau method are compared, the R is 0.76, 0.51 and 0.64 in groups 1 to 3, respectively. The absolute differences between actual AHs and the calculated AHs are greater than 1 SD (5.6 cm) in 15%, 35% and 28% of the patients in groups 1 to 3, respectively. CONCLUSION: This study validates and updates the previously established formula for predicting AH in girls with CPP. This updated formula can help clinicians to make treatment decisions. PMID- 30300411 TI - Antimicrobial treatment practices among Ugandan children with suspicion of central nervous system infection. AB - Acute central nervous system (CNS) infections in children in sub-Saharan Africa are often fatal. Potential contributors include late presentation, limited diagnostic capacity and inadequate treatment. A more nuanced understanding of treatment practices with a goal of optimizing such practices is critical to prevent avoidable case fatality. We describe empiric antimicrobial treatment, antibiotic resistance and treatment adequacy in a prospective cohort of 459 children aged two months to 12 years hospitalised for suspected acute CNS infections in Mbarara, Uganda, from 2009 to 2012. Among these 459 children, 155 had a laboratory-confirmed diagnosis of malaria (case-fatality rate [CFR] 14%), 58 had bacterial infections (CFR 24%) and 6 children had mixed malaria and bacterial infections (CFR 17%). Overall case fatality was 18.1% (n = 83). Of 219 children with laboratory-confirmed malaria and/or bacterial infections, 182 (83.1%) received an adequate antimalarial and/or antibiotic on the day of admission and 211 (96.3%) within 48 hours of admission. The proportion of those receiving adequate treatment was similar among survivors and non-survivors. All bacterial isolates were sensitive to ceftriaxone except one Escherichia coli isolate with extended-spectrum beta-lactamase (ESBL). The observed high mortality was not a result of inadequate initial antimicrobial treatment at the hospital. The epidemiology of CNS infection in this setting justifies empirical use of a third-generation cephalosporin, however antibiotic resistance should be monitored closely. PMID- 30300412 TI - The current status and effects of emergency drug shortages in China: Perceptions of emergency department physicians. AB - OBJECTIVES: The shortage of emergency drugs in China is severe. This study aimed to characterize emergency drug shortages in China and to measure their effects. METHODS: An online questionnaire based on a literature review was sent to emergency department physicians in Chinese secondary and tertiary hospitals from November 2016 to February 2017. The survey asked physicians questions about their experiences with emergency drug shortages. RESULTS: In total, 236 physicians from 29 provinces participated in the survey. According to their responses, 90.7% of the respondents experienced drug shortages during the last year. More than half of the physicians (65.7%) reported that drug shortages occurred at least once a month. Hospitals in the eastern and western regions of China had more emergency drugs in shortage than hospitals in central China, especially those with many inpatient beds (>=800). In addition, the shortage situation was more serious in secondary hospitals than in tertiary hospitals. More respondents agreed that original medicines, injections, essential medicines, medicines without alternative agents and cheap medicines were more susceptible to shortages than generics, oral medicines, nonessential medicines, medicines with alternative agents and expensive medicines, respectively. Most respondents thought that drug shortages always, often or sometimes affected patients [delayed therapy (62.6%), longer rescue and recovery times (58.9%) and higher costs (58.7%)] and physicians [inconvenience (81.0%), higher pressure (76.5%) and harm to patient-doctor relationships (72%)] and compromised hospital reputations (55.1%). CONCLUSIONS: The shortage of emergency drugs in China is serious, especially in secondary hospitals located in eastern and western China. Emergency drug shortages have significant effects on patients and physicians. PMID- 30300410 TI - Identification of gene expression predictors of occupational benzene exposure. AB - BACKGROUND: Previously, using microarrays and mRNA-Sequencing (mRNA-Seq) we found that occupational exposure to a range of benzene levels perturbed gene expression in peripheral blood mononuclear cells. OBJECTIVES: In the current study, we sought to identify gene expression biomarkers predictive of benzene exposure below 1 part per million (ppm), the occupational standard in the U.S. METHODS: First, we used the nCounter platform to validate altered expression of 30 genes in 33 unexposed controls and 57 subjects exposed to benzene (<1 to >=5 ppm). Second, we used SuperLearner (SL) to identify a minimal number of genes for which altered expression could predict <1 ppm benzene exposure, in 44 subjects with a mean air benzene level of 0.55+/-0.248 ppm (minimum 0.203ppm). RESULTS: nCounter and microarray expression levels were highly correlated (coefficients >0.7, p<0.05) for 26 microarray-selected genes. nCounter and mRNA-Seq levels were poorly correlated for 4 mRNA-Seq-selected genes. Using negative binomial regression with adjustment for covariates and multiple testing, we confirmed differential expression of 23 microarray-selected genes in the entire benzene exposed group, and 27 genes in the <1 ppm-exposed subgroup, compared with the control group. Using SL, we identified 3 pairs of genes that could predict <1 ppm benzene exposure with cross-validated AUC estimates >0.9 (p<0.0001) and were not predictive of other exposures (nickel, arsenic, smoking, stress). The predictive gene pairs are PRG2/CLEC5A, NFKBI/CLEC5A, and ACSL1/CLEC5A. They play roles in innate immunity and inflammatory responses. CONCLUSIONS: Using nCounter and SL, we validated the altered expression of multiple mRNAs by benzene and identified gene pairs predictive of exposure to benzene at levels below the US occupational standard of 1ppm.

AB - The treatment effect of the hybrid procedure, consisting of a thoracoscopic ablation followed by an endocardial radiofrequency catheter ablation (RFCA), is unclear. A total of 117 ablation-naive patients who underwent either the staged hybrid procedure (n = 72) or RFCA alone (n = 105) for drug-refractory, non valvular persistent or long-standing persistent atrial fibrillation (AF) were enrolled. The primary outcome is occurrence of total atrial arrhythmia, defined as a composite of AF, sustained atrial tachycardia (AT), and atypical atrial flutter (AFL) after index procedure. The mean age was 52.7 years. Eighty-four percentage of the patients were male. Patients with prior history of stroke and long-standing persistent AF were more prevalent in the hybrid group than RFCA group. The left atrial volume index was larger in the hybrid group (P<0.001). During 2.1 years of median follow-up, the incidence of total atrial arrhythmia was not different between the two groups (32.5% vs. 35.7%; adjusted hazard ratio: 0.64; 95% confidence interval: 0.36-1.14; P = 0.13). The AF recurrence was significantly lower in the hybrid group than in the RFCA group (29.6% vs. 34.9%; adjusted HR: 0.53; 95% CI: 0.29-0.99; P = 0.046). The hospital stay was longer in the hybrid group than in the RFCA group (11 days vs. 4 days; P<0.001). A staged hybrid procedure may be an alternative choice for drug-refractory persistent AF, but it is no more effective than RFCA alone to eliminate atrial arrhythmias. Considering the long-length of stay and the morbidity, careful consideration should be given in selection of treatment strategy. PMID- 30300414 TI - Parameters that remain consistent independent of pausing before gait-initiation during normal rise-to-walk behaviour delineated by sit-to-walk and sit-to-stand and-walk. AB - BACKGROUND: Rising-to-walk is an everyday transitional movement task rarely employed in gait rehabilitation. Sit-to-walk (STW) and sit-to-stand-and-walk (STSW), where a pause separates sit-to-stand and gait-initiation (GI) represent extremes of rising-to-walk behaviour. Delayed GI can indicate pathological impairment but is also observed in healthy individuals. We hypothesise that healthy subjects express consistent biomechanical parameters, among others that differ, during successful rising-to-walk task performance regardless of behaviour. This study therefore sought to identify if any parameters are consistent between STW and STSW in health because they represent normal rise-to walk performance independent of pause, and also because they represent candidate parameters sensitive enough to monitor change in pathology. METHODS: Ten healthy volunteers performed 5 trials of STW and STSW. Event timing, ground-reaction forces (GRFs), whole-body-centre-of-mass (BCoM) displacement, and centre-of pressure (CoP) to extrapolated BCoM (xCoM) distance (indicator of positional stability) up to the 3rd step were compared between-tasks with paired t-tests. For consistent parameters; agreement between-tasks was assessed using Bland Altman analyses and minimal-detectable-change (MDC) calculations. RESULTS: Mean vertical GRFs, peak forward momentum and fluidity during rising; CoP-xCoM separation at seat-off, upright, GI-onset, and steps1-2; and forward BCoM velocity were all significantly greater in STW. In contrast, peak BCoM vertical momentum, flexion-momentum time, and 3rd step stability were consistent between tasks and yielded acceptable reliability. CONCLUSION: STW is a more challenging task due to the merging of rising with GI reflected by greater CoP-xCoM separation compared to STSW indicative of more positional instability. However, BCoM vertical momentum, flexion-momentum time, and step3 stability remained consistent in healthy individuals and are therefore candidates with which to monitor change in gait rehabilitation following pathology. Future studies should impose typical pause-durations observed in pathology upon healthy subjects to determine if the parameters we have identified remain consistent. PMID- 30300415 TI - The usefulness of narrow band imaging in the assessment of laryngeal papillomatosis. AB - OBJECTIVES/HYPOTHESIS: Recurrent respiratory papillomatosis (RRP) is a benign disease caused by human papillomavirus 6 and 11. The characteristic feature of this disease are wart-like lesions covering the respiratory epithelium with a predilection for the larynx. There is no curative treatment for the disease. The goal of the treatment is a total surgical removal of the papillomatous lesions in order to reduce the number of relapses. Therefore, a good visualization method of papillomas is crucial during surgery. The aim of the study was to compare the accuracy of narrow band imaging (NBI) to the use of white light alone in detecting RRP. METHODS: The study was carried out between April 2013 and November 2015 at Poznan University of Medical Sciences, Department of Otolaryngology, Poland. Rigid endoscopy with conventional white light (WL) and NBI (CV-260SL processor and CLV- 260SL light source, Olympus Optical Co. Ltd, Tokyo, Japan) was performed in all patients during direct laryngoscopy. All anatomical sites of the larynx and trachea were assessed using the Dikkers scale and Derkay total site scoring system with WL and NBI. The consensus was reached as to the number of lesions seen in WL compared to NBI. RESULTS: During 36 microlaryngoscopies, the number of papillomas detected in the larynx (by Derkay total site score) differed significantly between white light endoscopy and NBI (Wilcoxon test p = 0.000655). In endoscopy with NBI, a mean of 1.3 more papillomas in Derkay total site score was detected in comparison to white light endoscopy NBI showed additional areas of diseased tissue in 15/36 (41.67%) patients. CONCLUSIONS: NBI as an additional tool during microlaryngoscopy can improve the detection of papillomatous lesions. PMID- 30300417 TI - A multi-agent system for distributed multi-project scheduling with two-stage decomposition. AB - A two-stage decomposition approach based on a novel multi-agent system (MAS) is proposed for the distributed resource constrained multi-project scheduling problem (DRCMPSP). In stage one, from the point of view of each local project manager, a forward-backward hybrid genetic algorithm (FBHGA) is developed to generate an initial local schedule with the objective of minimizing individual project makespan. In stage two, from the global perspective of project management office, a sequential game-based negotiation mechanism is employed to eliminate global resource conflicts with the objective of minimizing total tardiness cost (TTC). The proposed approach is tested on 140 benchmark problem instances. According to the computational results, high-quality local project schedules can be obtained by FBHGA in stage one. Furthermore, it is observed that our method is capable of dealing with various complex multi-project instances under different degrees of resource conflicts in reasonable CPU running time. Compared to the existing decentralized methods for DRCMPSP, the proposed approach with sequential game-based negotiation mechanism shows the superiority in producing multi-project schedules with lower TTC, especially for large-size and strong conflicting instances.

AB - BACKGROUND: In diabetes research, the development of the artificial pancreas has been a major topic since continuous glucose monitoring became available in the early 2000's. A prerequisite for an artificial pancreas is fast and reliable glucose sensing. However, subcutaneous continuous glucose monitoring carries the disadvantage of slow dynamics. As an alternative, we explored continuous glucose sensing in the peritoneal space, and investigated potential spatial differences in glucose dynamics within the peritoneal cavity. As a secondary outcome, we compared the glucose dynamics in the peritoneal space to the subcutaneous tissue. MATERIAL AND METHODS: Eight-hour experiments were conducted on 12 anesthetised non-diabetic pigs. Four commercially available amperometric glucose sensors (FreeStyle Libre, Abbott Diabetes Care Ltd., Witney, UK) were inserted in four different locations of the peritoneal cavity and two sensors were inserted in the subcutaneous tissue. Meals were simulated by intravenous infusions of glucose, and frequent arterial blood and intraperitoneal fluid samples were collected for glucose reference. RESULTS: No significant differences were discovered in glucose dynamics between the four quadrants of the peritoneal cavity. The intraperitoneal sensors responded faster to the glucose excursions than the subcutaneous sensors, and the time delay was significantly smaller for the intraperitoneal sensors, but we did not find significant results when comparing the other dynamic parameters.

PMID- 30300419 TI - Genomic profiling supports the diagnosis of primary ciliary dyskinesia and reveals novel candidate genes and genetic variants. AB - Primary ciliary dyskinesia (PCD) is a rare inherited autosomal recessive or X linked disorder that mainly affects lungs. Dysfunction of respiratory cilia causes symptoms such as chronic rhinosinusitis, coughing, rhinitis, conductive hearing loss and recurrent lung infections with bronchiectasis. It is now well known that pathogenic genetic changes lead to ciliary dysfunction. Here we report usage of clinical-exome based NGS approach in order to reveal underlying genetic causes in cohort of 21 patient with diagnosis of PCD. By detecting 18 (12 novel) potentially pathogenic genetic variants, we established the genetic cause of 11 (9 unrelated) patients. Genetic variants were detected in six PCD disease-causing genes, as well as in SPAG16 and SPAG17 genes, that were not detected in PCD patients so far, but were related to some symptoms of PCD. The most frequently mutated gene in our cohort was DNAH5 (27.77%). Identified variants were in homozygous, compound heterozygous and trans-heterozygous state. For detailed characterization of one novel homozygous genetic variant in DNAI1 gene (c. 947_948insG, p. Thr318TyrfsTer11), RT-qPCR and Western Blot analysis were performed. Molecular diagnostic approach applied in this study enables analysis of 29 PCD disease-causing and related genes. It resulted in mutation detection rate of 50% and enabled discovery of twelve novel mutations and pointed two possible novel PCD candidate genes. PMID- 30300420 TI - The impact and cost-effectiveness of controlling cholera through the use of oral cholera vaccines in urban Bangladesh: A disease modeling and economic analysis. AB - BACKGROUND: Cholera remains an important public health problem in major cities in Bangladesh, especially in slum areas. In response to growing interest among local policymakers to control this disease, this study estimated the impact and cost effectiveness of preventive cholera vaccination over a ten-year period in a high risk slum population in Dhaka to inform decisions about the use of oral cholera vaccines as a key tool in reducing cholera risk in such populations. METHODOLOGY/PRINCIPAL FINDINGS: Assuming use of a two-dose killed whole-cell oral cholera vaccine to be produced locally, the number of cholera cases and deaths averted was estimated for three target group options (1-4 year olds, 1-14 year olds, and all persons 1+), using cholera incidence data from Dhaka, estimates of vaccination coverage rates from the literature, and a dynamic model of cholera transmission based on data from Matlab, which incorporates herd effects. Local estimates of vaccination costs minus savings in treatment costs, were used to obtain incremental cost-effectiveness ratios for one- and ten-dose vial sizes. Vaccinating 1-14 year olds every three years, combined with annual routine vaccination of children, would be the most cost-effective strategy, reducing incidence in this population by 45% (assuming 10% annual migration), and costing was $823 (2015 USD) for single dose vials and $591 (2015 USD) for ten-dose vials per disability-adjusted life year (DALY) averted. Vaccinating all ages one year and above would reduce incidence by >90%, but would be 50% less cost-effective ($894-1,234/DALY averted). Limiting vaccination to 1-4 year olds would be the least cost-effective strategy (preventing only 7% of cases and costing $1,276 $1,731/DALY averted), due to the limited herd effects of vaccinating this small population and the lower vaccine efficacy in this age group. CONCLUSIONS/SIGNIFICANCE: Providing cholera vaccine to slum populations in Dhaka through periodic vaccination campaigns would significantly reduce cholera incidence and inequities, and be especially cost-effective if all 1-14 year olds are targeted. PMID- 30300421 TI - Femoral antecurvation-A 3D CT Analysis of 1232 adult femurs. AB - INTRODUCTION: For optimal treatment of femoral fractures, it is essential to understand the anatomical antecurvation of the human femur. Recent clinical studies have highlighted the problem of distal anterior encroachment or even perforation of the nail tip. The aim of this study was to accurately describe the femoral antecurvation in a large cohort. Another objective was to identify the most important influences on femoral antecurvation, such as age, femur length, gender and ethnicity. METHODS: A three dimensional modelling and analytical technology was applied for the analysis of 1,232 femurs. Individual femoral antecurvation was precisely computed to determine whether gender, femur length, age, ethnicity or body mass index influence the radius of curvature (ROC). RESULTS: The calculated mean ROC for all femurs was 943 mm. The lowest ROC of 826 mm was found in female Asian femurs. A regression analysis demonstrated that age and femur length could predict the variability of the curvature, with femoral length as most powerful predictor. A matched pair subgroup analysis between Asians and Caucasians could not show any significant differences of ROC values. CONCLUSIONS: The mean radius of the femoral antecurvation may be smaller than previously reported revealing a significant mismatch between the actual individual anatomy and existing implants. In opposite to existing literature, this study suggests, that antecurvation differences between various ethnicities may exclusively be attributed to differences in femoral length and age. The findings of this study may be found helpful in the development of novel designs for intra- and extramedullary implants.

AB - Working together allows social animals to accomplish tasks beyond the abilities of solitary individuals, but the benefits of cooperation must be balanced with the costs of coordination. Many ant species form cooperative groups to transport items too large for a single ant. However, transport by groups is often slower and less efficient than that of lone ants, for reasons that remain poorly understood. We tested the hypothesis that groups are slower when porters must encircle the load to carry it, because this arrangement places ants in a variety of postures relative to the load and the direction of travel. Porters may therefore have difficulty maximizing individual forces and aligning them with those of other group members. Experiments on the desert ant Novomessor cockerelli, an adept cooperative transporter, did not support this hypothesis. Groups ranging in size from one to four ants were induced to carry loads such that all porters were aligned with one another. Load weight was adjusted so that all porters pulled the same per capita weight, but lone porters were nonetheless faster than groups of any size. As group size increased, porters persisted in carrying the load for longer periods before letting go. We used simulations to explore a scenario in which ants vary in their intrinsic speed and the group's speed is limited by that of its slowest member. This proposed mechanism is analogous to other social groups where group efficiency is determined by the weakest link. We discuss how interactions among porters, mediated by the load itself, might explain such a constraint. PMID- 30300422 TI - Patient-centered primary care and self-rated health in 6 Latin American and Caribbean countries: Analysis of a public opinion cross-sectional survey. AB - BACKGROUND: Despite the substantial attention to primary care (PC), few studies have addressed the relationship between patients' experience with PC and their health status in low-and middle-income countries. This study aimed to (1) test the association between overall patient-centered PC experience (OPCE) and self rated health (SRH) and (2) identify specific features of patient-centered PC associated with better SRH (i.e., excellent or very good SRH) in 6 Latin American and Caribbean countries. METHODS AND FINDINGS: We conducted a secondary analysis of a 2013 public opinion cross-sectional survey on perceptions and experiences with healthcare systems in Brazil, Colombia, El Salvador, Jamaica, Mexico, and Panama; the data were nationally representative for urban populations. We analyzed 9 features of patient-centered PC. We calculated OPCE score as the arithmetic mean of the PC features. OPCE score ranged from 0 to 1, where 0 meant that the participant did not have any of the 9 patient-centered PC experiences, while 1 meant that he/she reported having all these experiences. After testing for interaction on the additive scale, we analyzed countries pooled for aim 1, with an interaction term for Mexico, and each country separately for aim 2. We used multiple Poisson regression models double-weighted by survey and inverse probability weights to deal with the survey design and missing data. The study included 6,100 participants. The percentage of participants with excellent or very good SRH ranged from 29.5% in Mexico to 52.4% in Jamaica. OPCE was associated with reporting excellent or very good SRH in all countries: adjusting for socio-demographic and health covariates, patients with an OPCE score of 1 in Brazil, Colombia, El Salvador, Jamaica, and Panama were more likely to report excellent or very good SRH than those with a score of 0 (adjusted prevalence ratio [aPR] 1.61, 95% CI 1.37-1.90, p < 0.001); in Mexico, this association was even stronger (aPR 4.27, 95% CI 2.34-7.81, p < 0.001). The specific features of patient-centered PC associated with better SRH differed by country. The perception that PC providers solve most health problems was associated with excellent or very good SRH in Colombia (aPR 1.38, 95% CI 1.01-1.91, p = 0.046) and Jamaica (aPR 1.21, 95% CI 1.02-1.43, p = 0.030). Having a provider who knows relevant medical history was positively associated with better SRH in Mexico (aPR 1.47, 95% CI 1.03-2.12, p = 0.036) but was negatively associated with better SRH in Brazil (aPR 0.71, 95% CI 0.56-0.89, p = 0.003). Finally, easy contact with PC facility (Mexico: aPR 1.35, 95% CI 1.04-1.74, p = 0.023), coordination of care (Mexico: aPR 1.53, 95% CI 1.19-1.98, p = 0.001), and opportunity to ask questions (Brazil: aPR 1.42, 95% CI 1.11-1.83, p = 0.006) were each associated with better SRH. The main study limitation consists in the analysis being of cross-sectional data, which does not allow making causal inferences or identifying the direction of the association between the variables. CONCLUSIONS: Overall, a higher OPCE score was associated with better SRH in these 6 Latin American and Caribbean countries; associations between specific characteristics of patient-centered PC and SRH differed by country. The findings underscore the importance of high quality, patient-centered PC as a path to improved population health. PMID- 30300424 TI - Southernmost records of Escarpia spicata and Lamellibrachia barhami (Annelida: Siboglinidae) confirmed with DNA obtained from dried tubes collected from undiscovered reducing environments in northern Chile. AB - Deep-sea fishing bycatch enables collection of samples of rare species that are not easily accessible, for research purposes. However, these specimens are often degraded, losing diagnostic morphological characteristics. Several tubes of vestimentiferans, conspicuous annelids endemic to chemosynthetic environments, were obtained from a single batch of deep-sea fishing bycatch at depths of around 1,500 m off Huasco, northern Chile, as part of an ongoing study examining bycatch species. DNA sequences of the mitochondrial cytochrome c oxidase subunit I (COI) gene and an intron region within the hemoglobin subunit B2 (hbB2i) were successfully determined using vestimentiferans' dried-up tubes and their degraded inner tissue. Molecular phylogenetic analyses based on DNA sequence identified the samples as Escarpia spicata Jones, 1985, and Lamellibrachia barhami Webb, 1969. These are the southernmost records, vastly extending the geographical ranges of both species from Santa Catalina Island, California to northern Chile for E. spicata (over 8,000 km), and from Vancouver Island Margin to northern Chile for L. barhami (over 10,000 km). We also determined a 16S rRNA sequence of symbiotic bacteria of L. barhami. The sequence of the bacteria is the same as that of E. laminata, Lamellibrachia sp. 1, and Lamellibrachia sp.2 known from the Gulf of Mexico. The present study provides sound evidence forthe presence of reducing environments along the continental margin of northern Chile.

AB - INTRODUCTION: The optimal fluid therapy in children with DKA is a matter of debate, especially if we take into account its association with cerebral edema, the most important complication. Hypertonic Saline Solution is used in the treatment of cerebral edema, and also has been used for volume resuscitation in children with shock. AIM OF STUDY: To compare the effects of 3% saline and 0.9% saline solutions on changes in vital parameters, sodium and chloride levels, lactate and pH; time needed for the correction of hyperglycemia; time needed for the control of ketoacidosis and incidence of cerebral edema. METHODS: Open-label prospective RCT in which 40 children with moderate to severe DKA were randomized to receive either 3% saline or 0.9% saline as initial fluid therapy. RESULTS: There was no significant difference between the two groups in the clinical vital parameters, time for the correction of hyperglycemia and the resolution of acidosis. Patients in the 3% saline group had a higher increase in sodium and chloride from baseline compared to the 0.9% saline group. The acidemia was noted to worsen in both groups after the initiation of fluid therapy, which was not associated with clinical deterioration. The frequency of cerebral edema was similar in both groups. CONCLUSIONS: Both 0.9% saline and 3% saline were equally effective as initial fluid in children with DKA with respect to hemodynamic improvement, the resolution of acidosis and the correction of hyperglycemia, but the use of 3% saline solution did not preclude the development of cerebral edema and has the potential to cause hypernatremia, hyperchloremia and hyperchloremic metabolic acidosis.

AB - Several studies have produced extensive evidence on white matter abnormalities in schizophrenia (SZ). However, optimum consistency and reproducibility have not been achieved, and reported low white matter tract integrity in patients with SZ varies between studies. A whole-brain imaging study with a large sample size is needed. This study aimed to investigate white matter integrity in the corpus callosum and connections between regions of interests (ROIs) in the same hemisphere in 122 patients with SZ and 129 healthy controls with public neuroimaging data from SchizConnect. For each diffusion-weighted image (DWI), two tensor full-brain tractography was performed; DWIs were parcellated by processing and registering T1 images with FreeSurfer and Advanced Normalization Tools. White matter query language was used to extract white matter fiber tracts. We evaluated group differences in means of diffusion measures between the patients and controls, and correlations of diffusion measures with the severity of clinical symptoms and cognitive impairment in the patients using the Positive and Negative Syndrome Scale (PANSS), a letter-number sequencing (LNS) test, vocabulary test, letter fluency test, category fluency test, and trail-making test, part A. To correct for multiple comparisons, a false discovery rate of q < 0.05 was applied. In patients with SZ, we observed significant radial diffusivity (RD) and trace (TR) increases in left thalamo-occipital tracts and the right uncinate fascicle, and a significant RD increase in the right middle longitudinal fascicle (MDLF) and the right superior longitudinal fascicle ii. Correlations were present between TR of left thalamo-occipital tracts, and the letter fluency test and the LNS test, and RD in the right MDLF and PANSS positive subscale score. However, these correlations were not significant after correction for multiple comparisons. These results indicated widespread white matter fiber tract abnormalities in patients with SZ, contributing to SZ pathophysiology.

AB - INTRODUCTION: Increasing incidence of excess weight and poor physical fitness of children validates the need for preventive actions. The Szczecin municipality (gmina Szczecin) runs the "Odwazna osemka" ("The Brave Eight") program - Prevention of excess weight and obesity in 8 and 9-year-old children attending elementary school in Szczecin, Poland. AIM: The assessment of physical fitness as well as the prevalence and intensity of excess body weight and blood pressure rates among the 8 and 9-year-old children attending elementary school in Szczecin, Poland. MATERIAL AND METHODS: Between 6th December 2016 and 3rd December 2017, 3407 8 and 9-year-old children were examined (1757 girls and 1650 boys). BMI (Body Mass Index) as well as WHR (Waist Hip Ratio) were calculated. All the children were assessed according to criteria established by the International Obesity Task Force (IOTF). The examination included basic anthropometric measurements, such as: body height and weight, waist and hip circumference, blood pressure, body constitution analysis, and physical fitness assessment. RESULTS: Excess body weight was diagnosed in 822 patients, which is 24.1% of the examined population. 369 patients were diagnosed with elevated blood pressure (10.8%). Very poor physical fitness - test abandoned before the completion (HR>180/min), was diagnosed in 151 children (4.5%), very poor physical fitness was diagnosed in 234 children (7%), poor physical fitness was diagnosed in 827 children (24.9%), sufficient physical fitness was diagnosed in 961 children (29.2%), good physical fitness was diagnosed in 650 children (19.5%), very good physical fitness was diagnose in 428 children (12.8%) and excellent in 70 children (2.1%). CONCLUSION: The fact of unsatisfactory physical fitness and excess body weight in children from Szczecin is unsettling. There is ceratainly a need for preventive measures in the broad sense.

AB - INTRODUCTION: Quality and quantity of food, consumed by a child have a great influence on his biological development. Dietary habits of children often do not meet criteria suggested by health institutions and schools. Nutrition of a child, involved in competitive sport should be rationally planned and obeyed. AIM: Comparison of dietary habits among two groups children: practicing swimming and non-athletes. MATERIALS AND METHOD: Research group consisted of 11-12-year-old children attending the same public primary school. Forty six students engaged in swimming training and forty two non-athletes were examined. The following anthropometrics variables had been measured: body height, body mass, percent body fat and body mass index. Dietary habits of the children were assessed by the survey, created on the basis of a tools available in literature. RESULTS: Children of both groups differed essentially in terms of percent body fat. Anyway, their body proportions meet the referred standards. A few differences were discovered in nutritional patterns among swimmers and non-athletes. Young swimmers more often consumed dinners at school. Moreover, swimming pupils ate dairy products more often than their peers, but ate fish less often. Non-athletes declared consumption of sweets more often when compared to the swimmers. CONCLUSIONS: Results of this study revealed insufficient number of consumed meal portions in both groups. There is a need of permanent nutritional education, provided by parents, teachers at school and sports coaches.

AB - INTRODUCTION: In patients who have undergone hematopoietic cell transplantation (HCT), the metabolic syndrome may develop without obesity defined by Body Mass Index (BMI). AIM OF THE STUDY: The aim of the study was to compare body fat parameters measured using bioelectrical impedance (BIA) and using standard parameters of obesity in patients treated with HCT and healthy controls. MATERIAL AND METHODS: We compared body fat (BF) and body fat percentage (BF%) measured using BIA in 44 patients before HCT and 28 patients after HCT, versus 26 controls. We also compared BMI and other BIA parameters in these groups of patients. RESULTS: The differences in BF and BF% between the patients before HCT and controls were not significant, while both BF and BF% were significantly lower in patients after HCT than in the control group. No significant differences in standard clinical obesity parameters were found in the patients before HCT, and in the patients after HCT, compared with the controls. The differences in other BIA parameters between the patients before HCT and the controls were not significant, while in the patients after HCT some parameters were significantly lower. CONCLUSION: Significant differences in BF and BF% in the patients after HCT compared with healthy controls suggest that BIA may be useful in screening for body fat abnormalities in patients after HCT. PMID- 30300430 TI - Endocrine disruptor compounds in environment: As a danger for children health. AB - Endocrine disrupting compounds (EDCs) are heterogenous in structure and include synthetic organic compounds such as pharmaceutical agents, plant protection products, plastics, plasticizers, polychlorinated biphenyls, dioxins, flame retardants, and antifoulant paint additive, as well, as natural plant-derived EDCs termed phytoestrogens and mycoestrogens. Children and adults are exposed daily to EDCs during drinking contaminated water, eating, breathing polluted air or direct contact with chemicals. Prenatal and perinatal period, infancy, childhood, and puberty are critical time of development during which maturing systems are particularly sensitive to hormonal disruptions (small elimination of xenobiotics). Exposure to environmental chemicals with estrogenic or antiandrogenic action may disrupt female reproductive tract development, also testosterone synthesis and sexual differentiation, leading to adult testis dysfunction and infertility. What is important, today there is still no definitive risk assessment tool for EDCs.

AB - Vitamin D activity is controlled by its receptor (VDR) located in many cells of the body. The presence of VDR in numerous cellular pathways suggests its important role in the etiology and development of many diseases. Increased risk of obesity, metabolic disturbances, bone mass disturbances and neoplasia among certain VDR alleles has been proven. The importance of VDR in the etiopathology of obesity is associated with the occurrence of polymorphisms: Fok1, Bsm1, Apa1, Taq1. VDR expression in adipocytes plays a role in the regulation of energy metabolism and the induction of obesity. Vitamin D and VDR polymorphisms can participate in the development of many metabolic disorders. The VDR gene is one of the better researched genes among patients with type 1 diabetes. The action of vitamin D affects the proper functioning and development of the skeletal system. Vitamin D has an effect on bone remodeling through its receptor and its polymorphisms: Apa1, Bsm1, Taq1, Fok1 and Cdx2. The identification and diagnosis of VDR varieties gives the possibility of early detection of the risk of osteoporosis or individual predisposition to its development. There is a high variability in the results of individual VDR polymorphisms in relation to the occurrence of osteoporosis among various ethnic groups. The polymorphisms important in the neoplastic process include, among others, the polymorphism of Fok1, Bsm1, and Taq1. The association of VDR gene polymorphisms with the risk of breast cancer (Bsm1, Fok1), prostate cancer (Fok1) and malignant melanoma (Fok1) is indicated. The greatest importance in the prognosis is observed in patients with prostate cancer (F1), breast cancer (Bsm1, Taq1), malignant melanoma (Bsm1) and renal cell carcinoma (Taq1). It is important to identify, describe and correlate the occurrence of genetic polymorphisms of the VDR, which will allow early diagnosis or prevention of correlative entities correlated with them.

AB - Hypercalcemia may occur in approximately 15% of children with the Williams-Beuren syndrome. The episodes of hypercalcemic crisis usually respond well to initial hyperhydration, loop diuretics and calcitonin, bisphosphonates, or subsequent dialysis. However, many patients suffer from recurrent or persistent hypercalcemia after the resolution of the hypercalcemic crisis. Although hypercalcemia in the Williams-Beuren syndrome is generally considered transient, it may last for several months, result in significant morbidity, and compromise physical growth. There are no guidelines for the management of persistent or recurrent hypercalcemia in patients with the Williams-Beuren syndrome. In this report, we describe our experience of conducting oral corticosteroid therapy in a child with the Williams-Beuren syndrome who continued to have hypercalcemia after the resolution of the hypercalcemic crisis. PMID- 30300438 TI - Long-term effects of delayed graft function duration on function and survival of deceased donor kidney transplants. AB - INTRODUCTION: Delayed graft function (DGF) is a frequent complication after deceased donor kidney transplantation with an impact on the prognosis of the transplant. Despite this, long-term impact of DGF on graft function after deceased donor kidney transplantation has not been properly evaluated. OBJECTIVE: The main objective of this study was to evaluate risk factors for DGF and the impact of its occurrence and length on graft survival and function. METHODS: A retrospective cohort study was performed in 517 kidney transplant recipients who received a deceased donor organ between January 2008 and December 2013. RESULTS: The incidence of DGF was 69.3% and it was independently associated with donor's final serum creatinine and age, cold ischemia time, use of antibody induction therapy and recipient's diabetes mellitus. The occurrence of DGF was also associated with a higher incidence of Banff >= 1A grade acute rejection (P = 0.017), lower graft function up to six years after transplantation and lower death-censored graft survival at 1 and 5 years (P < 0.05). DGF period longer than 14 days was associated with higher incidence of death-censored graft loss (P = 0.038) and poorer graft function (P < 0.001). No differences were found in patient survival. CONCLUSIONS: The occurrence of DGF has a long-lasting detrimental impact on graft function and survival and this impact is even more pronounced when DGF lasts longer than two weeks.

AB - All-polymer solar cells (all-PSCs) have attracted immense attention in recent years due to their advantages of tunable absorption spectra and electronic energy levels for both donor and acceptor polymers, as well as their superior thermal and mechanical stability. The exploration of the novel n-type conjugated polymers (CPs), especially based on aromatic diimide (ADI), plays a vital role in the further improvement of power conversion efficiency (PCE) of all-PSCs. Here, recent progress in structure modification of ADIs including naphthalene diimide (NDI), perylene diimide (PDI), and corresponding derivatives is reviewed, and the structure-property relationships of ADI-based CPs are revealed. PMID- 30300440 TI - Pharmacokinetics of the Meropenem Component of Meropenem-Vaborbactam in the Treatment of KPC-Producing Klebsiella pneumoniae Bloodstream Infection in a Pediatric Patient. AB - Meropenem-vaborbactam is a new beta-lactam/beta-lactamase inhibitor combination designed to target Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae. Meropenem-vaborbactam was United States Food and Drug Administration-approved for complicated urinary tract infections in patients 18 years of age or older. An understanding of the pharmacokinetics of meropenem when given in combination with vaborbactam is important to understanding the dosing of meropenem-vaborbactam. In addition, the safety and efficacy of meropenem vaborbactam in a pediatric patient have yet to be described in the literature. The authors conducted a retrospective single-patient chart review for a 4-year old male patient with short bowel syndrome, colostomy and gastrojejunal tube, bronchopulmonary dysplasia, and a central line for chronic total parenteral nutrition and hydration management, complicated with multiple central line associated bloodstream infections (BSIs). The patient was brought to our medical center with fever concerning for a BSI. On day 2, the patient was started on meropenem-vaborbactam at a dosage of 40 mg/kg every 6 hours infused over 3 hours for KPC-producing K. pneumoniae BSI. Meropenem serum concentrations obtained on day 5 of meropenem-vaborbactam therapy, immediately following the completion of the infusion and 1 hour after the infusion, were 51.3 and 13.6 MUg/ml, respectively. Serum concentrations correlated to a volume of distribution of 0.59 L/kg and a clearance of 13.1 ml/min/kg. Repeat blood cultures remained negative, and meropenem-vaborbactam was continued for a total of 14 days. A meropenem vaborbactam regimen of 40 mg/kg every 6 hours given over 3 hours was successful in providing a target attainment of 100% for meropenem serum concentrations above the minimum inhibitory concentration for at least 40% of the dosing interval and was associated with successful bacteremia clearance in a pediatric patient. PMID- 30300441 TI - Clinical Utility of Methicillin-Resistant Staphylococcus aureus Nasal Screening for Antimicrobial Stewardship: A Review of Current Literature. AB - Significant clinical and financial consequences are associated with both inadequate and unnecessary exposure to broad-spectrum antibiotics. As such, antimicrobial stewardship programs seek objective, reliable, and cost-effective tests to identify patients at highest or lowest risk for drug-resistant organisms to guide empirical antimicrobial selection. Use of methicillin-resistant Staphylococcus aureus (MRSA) nasal screening to rule out MRSA in lower respiratory tract infections has led to significant reductions in duration of vancomycin therapy. The clinical utility of MRSA nasal screening in other types of infection remains less clear. This review describes the performance of MRSA nasal screening in predicting MRSA infection, highlights practical considerations for use of MRSA nasal screening, and provides guidance for incorporating MRSA nasal screening into clinical practice. With a high negative predictive value when the prevalence of MRSA is low, MRSA nasal screening is a valuable antimicrobial stewardship tool with potential applications beyond lower respiratory tract infections. In appropriately selected patients, negative MRSA nasal screening can prevent initiation or guide discontinuation of anti-MRSA therapy. Antimicrobial stewardship programs should develop institutional guidelines to promote proper use of MRSA nasal screening. Pharmacists are well positioned to assist with education, interpretation, and application of MRSA nasal screening results. PMID- 30300442 TI - Flexible and Implantable Microelectrodes for Chronically Stable Neural Interfaces. AB - Implantable electrical probes that can record neural activities at single-neuron and sub-millisecond resolution are the most widely applied tools in both neuroscience research and neuroprosthetics. However, the structural and mechanical mismatch between conventional rigid probes and neural tissues results in inflammatory responses and signal degradation over chronic recordings. Reducing the cross-sectional footprints and rigidity of the probes can effectively improve the long-term stability of neural interfaces. Herein, recent progress in the development of implantable microelectrodes for chronically stable neural interfaces is highlighted, with a focus on the utilization of advanced materials and structural design concepts.

AB - Engineering the morphology and structure of low-dimensional carbon nanomaterials is important to study their mechanical and electrical properties and even superconductivity. Herein, first the techniques that are used to engineer carbon nanotubes, including manipulation, morphology modification, and fabrication of complex nanostructures, are reviewed. This is followed by a summary of the methods applied to fabricate graphene nanostructures, such as heterostructures and nanoenvelopes of graphene.

PMID- 30300444 TI - Advanced Carbon for Flexible and Wearable Electronics. AB - Flexible and wearable electronics are attracting wide attention due to their potential applications in wearable human health monitoring and care systems. Carbon materials have combined superiorities such as good electrical conductivity, intrinsic and structural flexibility, light weight, high chemical and thermal stability, ease of chemical functionalization, as well as potential mass production, enabling them to be promising candidate materials for flexible and wearable electronics. Consequently, great efforts are devoted to the controlled fabrication of carbon materials with rationally designed structures for applications in next-generation electronics. Herein, the latest advances in the rational design and controlled fabrication of carbon materials toward applications in flexible and wearable electronics are reviewed. Various carbon materials (carbon nanotubes, graphene, natural-biomaterial-derived carbon, etc.) with controlled micro/nanostructures and designed macroscopic morphologies for high-performance flexible electronics are introduced. The fabrication strategies, working mechanism, performance, and applications of carbon-based flexible devices are reviewed and discussed, including strain/pressure sensors, temperature/humidity sensors, electrochemical sensors, flexible conductive electrodes/wires, and flexible power devices. Furthermore, the integration of multiple devices toward multifunctional wearable systems is briefly reviewed. Finally, the existing challenges and future opportunities in this field are summarized. PMID- 30300445 TI - Population Pharmacokinetics of Gentamicin in Neonates with Hypoxemic-Ischemic Encephalopathy Receiving Controlled Hypothermia. AB - OBJECTIVE: Identify population pharmacokinetics and pharmacodynamic target attainment of gentamicin in neonates with hypoxic-ischemic encephalopathy (HIE) undergoing controlled hypothermia (CH). DESIGN: Prospective open-label pharmacokinetic study. Gentamicin concentrations were modeled and dosing regimens simulated for a 5000-patient neonatal population with HIE receiving CH using PMetrics, a nonparametric, pharmacometric modeling, and simulation package for R. SETTING: A 189-bed children's tertiary care teaching hospital. RESULTS: Twelve patients, 5 (42%) females and 7 (58%) males, met inclusion criteria with a median gestation age of 39.9 weeks (interquartile range [IQR] 38.5-40.2 wks) and a median birthweight (BW) of 3.3 kg (IQR 3.1-3.7 kg). Gentamicin concentrations were best described by a two-compartment model with first-order elimination with BW as a covariate on volume of distribution (Vd). The mean total body population clearance (CL) was 2.2 +/- 0.7 ml/minute/kg, and the volume of the central compartment was 0.44 +/- 0.06 L/kg. The R2 , bias, and precision for the observed versus population predicted model were 0.917, 1.15, and 10.9 MUg/ml; the R2 , bias, and precision for the observed versus individual predicted model were 0.982, -0.132, and 0.932 MUg/ml, respectively. The calculated mean population estimate for the total Vd was 0.96 +/- 0.4 L/kg. The dosing regimen that most consistently produced a maximum concentration (Cmax ) in the range of 10-12 mg/L with a minimum concentration (Cmin ) level less than 2 mg/L was 5 mg/kg/dose given every 36 hours. CONCLUSION: These data suggest the population pharmacokinetics of gentamicin in neonates with HIE receiving CH have an increase in gentamicin CL and are different from previous reports in neonates with HIE not receiving CH and/or neonates without HIE. This analysis suggests a dosing regimen of 5 mg/kg/dose every 36 hours results in a gentamicin Cmax within the range of 10-12 mg/L with a Cmin lower than 2 mg/L, which is appropriate for treating susceptible gram-negative organisms with minimum inhibitory concentrations of 1 mg/L or lower. PMID- 30300447 TI - Effect of resilience on intolerance of uncertainty in nursing university students. AB - PURPOSE: Nursing students must cope in a complex and uncertain society. We identified the relationship between resilience and intolerance of uncertainty (IOU) in nursing students. METHODS: Data were collected from November 10 to 20, 2016, from 134 Korean nursing students (male = 21, female = 113; first-year = 39, second-year = 39, third-year = 35, and fourth-year = 21), using a questionnaire. The measures in this study included resilience and IOU. RESULTS: Differences in IOU relating to participants' general characteristics showed that IOU was high when the major satisfaction was rated as "middle" rather than "high." Participants' IOU was significantly negatively correlated with the following resilience subdomains: self-regulation skills, interpersonal skills, and positive tendencies. In particular, higher positive tendencies led to lower levels of IOU. CONCLUSION: It is vital to devise strategies to advance nursing students' satisfaction toward their major and positive tendencies to reduce the level of IOU. This will prepare nursing students for various programs and improve their outcomes at school. PMID- 30300446 TI - The dynamics of cortical GABA in human motor learning. AB - KEY POINTS: The ability to learn new motor skills is supported by plasticity in the structural and functional organisation of the primary motor cortex in the human brain. Changes inhibitory to signalling by GABA are thought to be crucial in inducing motor cortex plasticity. This study used magnetic resonance spectroscopy (MRS) to quantify the concentration of GABA in human motor cortex during a period of motor learning, as well as during a period of movement and a period at rest. We report evidence for a reduction in the MRS-measured concentration of GABA specific to learning. Further, the GABA concentration early in the learning task was strongly correlated with the magnitude of subsequent learning: higher GABA concentrations were associated with poorer learning. The results provide initial insight into the neurochemical correlates of cortical plasticity associated with motor learning, specifically relevant in therapeutic efforts to induce cortical plasticity during recovery from stroke. ABSTRACT: The ability to learn novel motor skills is a central part of our daily lives and can provide a model for rehabilitation after a stroke. However, there are still fundamental gaps in our understanding of the physiological mechanisms that underpin human motor plasticity. The acquisition of new motor skills is dependent on changes in local circuitry within the primary motor cortex (M1). This reorganisation has been hypothesised to be facilitated by a decrease in local inhibition via modulation of the neurotransmitter GABA, but this link has not been conclusively demonstrated in humans. Here, we used 7 T magnetic resonance spectroscopy to investigate the dynamics of GABA concentrations in human M1 during the learning of an explicit, serial reaction time task. We observed a significant reduction in GABA concentration during motor learning that was not seen in an equivalent motor task lacking a learnable sequence, nor during a passive resting task of the same duration. No change in glutamate was observed in any group. Furthermore, M1 GABA measured early in task performance was strongly correlated with the degree of subsequent learning, such that greater inhibition was associated with poorer subsequent learning. This result suggests that higher levels of cortical inhibition may present a barrier that must be surmounted in order to achieve an increase in M1 excitability, and hence encoding of a new motor skill. These results provide strong support for the mechanistic role of GABAergic inhibition in motor plasticity, raising questions regarding the link between population variability in motor learning and GABA metabolism in the brain. PMID- 30300448 TI - Persistent inaccuracies in completion of medical certificates of stillbirth: A cross-sectional study. AB - BACKGROUND: The UK Medical Certificate of Stillbirth (MCS) records information relevant to the cause of stillbirth of infants >=24 weeks' gestation. A cross sectional audit demonstrated widespread inaccuracies in MCS completion in 2009 in North West England. A repeat study was conducted to assess whether practice had improved following introduction of a regional care pathway. METHODS: 266 MCS issued in 14 North West England obstetric units during 2015 were studied retrospectively. Cause of death was assigned following review of information available at the time of MCS completion. This was compared to that documented on the MCS, and to data from 2009. RESULTS: Twenty-three certificates were excluded (20 inadequate data, 3 late miscarriages). 118/243 (49%) MCS contained major errors. Agreement between the MCS and adjudicated cause of stillbirth was fair (Kappa 0.31; 95% CI 0.24, 0.38) and unchanged from 2009 (0.29). In 2015, excluding 34 terminations of pregnancy, the proportion of MCSs documenting "unexplained" stillbirths (113/211; 54%) was reduced compared to 2009 (158/213; 74%); causality could be assigned after case note review in 78% cases. Recognition of fetal growth restriction (FGR) as a cause of stillbirth improved (2015: 30/211; 14% vs 2009: 1/213; 0.5%), although 71% cases were missed. 47% MCSs following termination of pregnancy documented an iatrogenic primary cause of death. CONCLUSIONS: Completion of MCSs remains inaccurate, particularly in recognition of FGR as a cause of stillbirth. Detailed case note review before issuing the MCS could dramatically improve the usefulness of included information; evaluation of practitioner education programmes/internal feedback systems are recommended. PMID- 30300450 TI - Effect of reducing acid-etching duration time on compressive strength and bonding of a universal adhesive to calcium silicate cements. AB - AIM: To assess the effect of acid-etching duration time on the compressive strength, microstructure and shear bond strength of All-Bond Universal adhesive to MTA-Angelus (AMTA), and Biodentine (BD). METHODOLOGY: Forty-eight cylindrical specimens (4 mm in diameter, 6 mm in height) of AMTA in four groups and 48 specimens of BD in four groups (n = 12) were prepared and stored for 72 h. The control groups were unetched whilst the three experimental groups were acid etched for 5, 10 and 15 s, respectively, followed by compressive strength testing. The effect of the various acid-etching times on surface micromorphology was evaluated under a scanning electron microscope. Similar groups were bonded using All-Bond Universal and Aelite Flo and shear bond strength was tested. Data were analysed using two-way ANOVA and Tukey tests. RESULTS: 10-s and 15-s acid etching reduced the compressive strength of AMTA and BD (P < 0.001), while 5-s etching did not (P <= 0.86). In all the groups, BD had greater compressive strength compared to AMTA. Contrary to BD, the three etched AMTA groups had significantly higher shear bond strength compared to the control group (P < 0.001), with no significant differences between them. The etched groups of AMTA had shear bond strengths comparable to all the BD groups. Scanning electron microscope observations indicated variable surface morphologies such as remnant crystals and cracking/eroding in all our groups of AMTA; though these differences were less prominent for BD. CONCLUSIONS: Shortening the acid-etching time to 5 s resulted in a beneficial effect in terms of resin bonding for AMTA while preventing the detrimental effect of 10-s and 15-s etching on the compressive strength of AMTA and BD. However, the three etching times had no effect on resin BD bond. PMID- 30300451 TI - Shining light on the paraventricular nucleus: the role of glutamatergic PVN neurons in blood pressure control. PMID- 30300449 TI - Deferasirox in children with transfusion-dependent thalassemia or sickle cell anemia: a large cohort real-life experience from Turkey (REACH-THEM). AB - OBJECTIVES: To evaluate the long-term efficacy and safety of deferasirox therapy in a large observational cohort of children with transfusion-dependent thalassemia (TDT) and sickle cell anemia (SCA) in Turkey. METHODS: This was a multicenter, prospective cohort study including TDT and SCA patients aged 2-18 years with iron overload (>=100 mL/kg of pRBC or a serum ferritin [SF] level >1000 MUg/L) receiving deferasirox. Patients were followed for up to 3 years according to standard practice. RESULTS: 439 patients were evaluated (415 [94.5%] TDT, 143 [32.6%] between 2-6 years). SF levels consistently and significantly decreased across 3 years of deferasirox therapy from a median of 1775.5 to 1250.5 MUg/L (p<0.001). SF decreases were noted in TDT (1804.9 to 1241 MUg/L), SCA (1655.5 to 1260 MUg/L), and across age groups 2-6 years (1971.5 to 1499 MUg/L), 7 12 years (1688.5 to 1159.8 MUg/L), and 13-18 years (1496.5 to 1107 MUg/L). SF decreases were also noted for all deferasirox dose groups but only significant in patients with doses >=30 mg/kg/day (n=120, -579.6 median reduction, p<0.001). Only 9 (2%) patients had adverse events suspected to be related to deferasirox. Serum creatinine slightly increased but remained within the normal range. CONCLUSIONS: Deferasirox has long-term efficacy and safety in children with TDT and SCA, although higher doses (>=30 mg/kg/day) may be required to achieve iron balance.

PMID- 30300454 TI - Differences between chronic and nonchronic depression: Systematic review and implications for treatment. AB - BACKGROUND: There is still uncertainty if and to what extent chronic depression (CD) presents with specific features especially in contrast to the nonchronic course of major depressive disorder (non-CD). This systematic review aims to summarize the existing literature regarding sociodemographic factors, psychopathology, and course of disease in patients with CD in comparison to patients with non-CD. METHODS: A structured database search (MEDLINE, PsycINFO, Web of Science, CENTRAL) was performed. All studies comparing CD with non-CD patients were included. Twenty-eight studies, including cohort studies, cross sectional studies, and observational studies, were identified in which both subgroups were diagnosed according to DSM-IV or DSM-5, respectively. Primary outcome were group comparisons focused on sociodemographic factors, childhood adversity, onset of the disorder, comorbidities, severity and course of the depressive symptoms, and specific psychopathology. RESULTS: Patients with CD had an earlier onset of depressive symptoms, higher rates of psychiatric comorbidities, and a complicated treatment course (e.g., higher rates of suicidality) compared to non-CD. We also found some evidence for specific features in the psychopathology of CD patients (submissive and hostile interpersonal styles) in contrast to non-CD patients. Results were inconsistent with regard to childhood maltreatment. No differences were found regarding the severity of depressive symptoms and most sociodemographic factors. CONCLUSION: Despite some inconsistencies, the results of this review verified important differences between CD and non-CD. However, future research is needed to characterize especially the specific psychopathology of CD in comparison to non CD patients to develop more tailored treatment strategies. PMID- 30300455 TI - Disturbed sleep in cluster headache is not the result of transient processes associated with the cluster period. AB - BACKGROUND AND PURPOSE: Cluster headache (CH) is characterized by severe, unilateral attacks of pain and a high nocturnal attack burden. It remains unknown whether perturbations of sleep are solely present during the CH bout. Therefore, we aimed to investigate differences in sleep between the bout and remission period in patients with episodic CH and, secondly, to compare patients in the two phases with controls. METHODS: Patients with episodic CH (aged 18-65 years), diagnosed according to the International Classification of Headache Disorders 2nd edition, were admitted for polysomnography at the Danish Center for Sleep Medicine in bout and in remission. The macrostructure of sleep, including arousals, breathing parameters, limb movements and periodic limb movements, was compared with 25 age-, sex- and body mass index-matched healthy controls. RESULTS: There were no differences in any of the sleep parameters for patients in bout (n = 32) compared with patients in remission (n = 23). Attacks were unrelated to sleep stages, presence of apnea episodes, periodic limb movements, limb movements and arousals. In bout, patients had longer sleep latency (18.8 vs. 11.7 min, P < 0.05) and rapid eye movement sleep latency (1.7 vs. 1.2 h, P < 0.05) than controls and sleep efficiency was lower (82.5% vs. 86.5%, P < 0.05). Patients in remission only had a longer sleep latency compared with controls (17.5 vs. 11.7 min, P < 0.01). CONCLUSIONS: The results support the presence of a continuing or slowly recovering disturbance of sleep outside the bout rather than a disturbance occurring secondary to attacks. Further, we confirm that there is no relation between CH attacks and specific sleep stages or between CH and breathing parameters. PMID- 30300456 TI - "Green" UV-LED gel nail polishes from bio-based materials. AB - OBJECTIVE: Gel nail polishes represent an advanced class of nail polishes, with the ability to cure under ultraviolet (UV) radiation, and consequently demonstrate improved properties and greater durability compared to conventional nail polishes. Most gel nail polishes available today are based on petrochemical resources, making them unsustainable. Bio-based materials are excellent renewable resources, with high potential for meeting final-product performance, cost, and environmental needs. In addition, bio-based materials can be modified to make them amenable to being cured by advanced Light Emitting Diode (LED) resources that consume low energy and are safer for human exposure compared to conventional UV-mercury lamps. Consumer preference for use of products made from bio-based sources has been clearly growing. On the other hand, according to the U.S. Department of Energy (DOE) technology roadmap, a considerable amount of basic chemical building blocks should be derived from plant-based renewable materials in near future. However, to the best of our knowledge, bio-based nail products have not been sufficiently explored. Therefore, to keep pace with environmental regulations and consumer preference, there is an unmet opportunity to develop novel, sustainable nail gel polishes with considerable bio-renewable content. In this study, two sustainable UV-LED curable gel nail polish prototypes-one high solids zero-volatile organic content (VOC) and the other waterborne, both with considerable bio-renewable content, were designed. METHODS: Both formulations were cured under both UV-mercury and UV-LED radiation sources in order to evaluate their curing efficiency under a UV-LED source. Also, their performance was compared with a commercial petro-based benchmark. RESULTS: The high-solids formulation demonstrated promising performance, exceeding that of the benchmark in opacity, chemical properties, gloss, and pendulum hardness, while the waterborne formulation met most of the desirable requirements with some significant technical benefits, including low odour and higher renewable raw material content. CONCLUSION: These novel gel nail polishes are greener alternatives to the current products in the market with high potential for promising consumer acceptance. PMID- 30300457 TI - Multiple sclerosis - a review. AB - Multiple sclerosis (MS) is the commonest non-traumatic disabling disease to affect young adults. The incidence of MS is increasing worldwide, together with the socioeconomic impact of the disease. The underlying cause of MS and mechanisms behind this increase remain opaque, although complex gene-environment interactions almost certainly play a significant role. The epidemiology of MS indicates that low serum levels of vitamin D, smoking, childhood obesity and infection with the Epstein-Barr virus are likely to play a role in disease development. Changes in diagnostic methods and criteria mean that people with MS can be diagnosed increasingly early in their disease trajectory. Alongside this, treatments for MS have increased exponentially in number, efficacy and risk. There is now the possibility of a diagnosis of 'pre-symptomatic MS' being made; as a result potentially preventive strategies could be studied. In this comprehensive review, MS epidemiology, potential aetiological factors and pathology are discussed, before moving on to clinical aspects of MS diagnosis and management. PMID- 30300458 TI - High burden of neurological disease in the older general population: results from the Canadian Longitudinal Study on Aging. AB - BACKGROUND AND PURPOSE: Our objective was to study the association between the presence of a neurological disease and the comorbidity burden as well as healthcare utilization (HCU). METHODS: Using baseline data from the Canadian Longitudinal Study on Aging (CLSA), we examined the burden of five neurological conditions. The CLSA is a population-based study of approximately 50 000 individuals, aged 45-85 years at baseline. We used multivariable Poisson regression to identify correlates of comorbidity burden and HCU. RESULTS: The lifetime prevalence of five neurological diseases is presented: epilepsy, Parkinson's disease/parkinsonism, stroke/transient ischaemic attack, multiple sclerosis and migraine. We found the somatic and psychiatric comorbidity burden to be higher in those individuals with a neurological disease (an 18-45% mean increase in the number of chronic conditions) as compared with the comparison group without a neurological disease, except for Parkinson's disease/parkinsonism. The presence of a neurological disease was associated with only a modest increase in the probability of visiting a general practitioner but was associated with a greatly increased probability of visiting a medical specialist (up to 68% more likely) or an emergency department (up to 79% more likely) and an overnight hospitalization (up to 108% more likely). CONCLUSIONS: We found striking associations between our neurological diseases and increased comorbidity burdens and HCU. These findings are important for informing public policy planning as well as driving avenues for future research. The present study established the CLSA as an important research platform for the study of neurological conditions in an aging general population. PMID- 30300459 TI - CNT Interwoven Nitrogen and Oxygen Dual-Doped Porous Carbon Nanosheets as Free Standing Electrodes for High-Performance Na-Se and K-Se Flexible Batteries. AB - Na-Se and K-Se batteries are attractive as a stationary energy storage system because of much abundant resources of Na and K in the Earth's crust. As the alloy type Se has a severe pulverization issue, one critical challenge to develop advanced Na-Se and K-Se batteries is to explore a highly efficient and stable Se based cathode. Herein, a flexible free-standing Se/carbon composite film is prepared by encapsulation of Se into a carbon nanotube (CNT) interwoven N,O dual doped porous carbon nanosheet (Se@NOPC-CNT). The 3D interconnected CNT uniformly wrapped on the N,O dual-doped porous carbon skeletons improves the flexibility and offers an interconnected conductive pathway for rapid ionic/electronic transport. In addition, the N,O dual-doping significantly enhances the chemical affinity and adhesion between Nax Se/Kx Se (0 < x <= 2) and porous carbon, which is confirmed by density functional theory calculation. When used as the cathode in Na-Se batteries, the Se@NOPC-CNT delivers a remarkable reversible capacity of 400 mA h g-1 at 1 A g-1 after 2000 cycles with a 0.008% capacity decay per cycle. For K-Se batteries, it also exhibits an excellent cycling stability (335 mA h g-1 after 700 cycles at 0.8 A g-1 ). This unique design may open an avenue for practical application of flexible Na-Se and K-Se batteries. PMID- 30300460 TI - The morphogenesis of the renal plexus: Renal artery and sympathetic fibers. AB - To examine the origin and development of the renal plexus and its relationship to the renal vessels in embryos and early human fetuses. Serial sections of 34 human embryos (stages 16 to 23 of Carnegie, 4 or 5-8 weeks) and 38 fetuses (9-19 weeks) were analyzed. Throughout the embryonic period, the kidney was not innervated by the renal plexus. Those nerves appeared at the beginning of the early fetal period (9 weeks) as branches given off by the immature autonomic abdominal plexus. The renal nerves started to approach to the kidney during the early fetal period at 9-10 weeks of development. They were distributed in close proximity to the renal arteries and their branches. They were observed first with the settlement of the renal veins. The renal artery is present as a branch of the abdominal aorta at stage 19 (between 6 and 7 weeks) prior to development of the renal plexus. The renal veins were not present during the embryonic period but appeared at the start of the fetal period, along with the renal nerves that emerged from segmented sympathetic para-aortic bodies (SPBs).

PMID- 30300462 TI - Adiponectin profile at baseline is correlated to progression and severity of multiple sclerosis. AB - BACKGROUND AND PURPOSE: Adiponectin is a cytokine linking energy metabolism and immune system. After being assembled, adiponectin circulates as oligomers of different molecular weight, i.e. low, medium and high (HMW) molecular weight. These have the most potent biological effects. Multiple sclerosis (MS) is an autoimmune disease of the human central nervous system. The aim of this study was to characterize the expression levels of both total adiponectin and its oligomerization state in the serum from 99 patients with MS at baseline (i.e. not influenced by therapies). We also investigated the potential relationships between adiponectin and disease progression and severity. METHODS: Adiponectin was quantified and visualized by enzyme-linked immunosorbent assay, western blotting and fast protein liquid chromatography. During the follow-up (3.6 +/- 2.20 years), the patients were evaluated using total annualized relapse rate and Expanded Disability Status Scale score. RESULTS: Total adiponectin is statistically higher in patients with MS compared with matched controls (12.18 vs. 10.02 MUg/mL, P = 0.001). Interestingly, the adiponectin oligomerization state is altered in MS, with an increase of HMW oligomers. In addition, patients with MS with higher levels of adiponectin at baseline have significantly higher risk of progression and severity (Multiple Sclerosis Severity Score, 3.84 vs. 2.44, P = 0.001). No statistical difference in adiponectin expression was found between active and inactive patients with MS and among the different forms of disease. CONCLUSIONS: This study demonstrated that adiponectin and its HMW oligomers are greatly involved in MS autoimmune disorder representing a potential biomarker to predict worse MS prognosis and severity. Further studies are required to clarify the molecular mechanisms underlying the properties of adiponectin and HMW oligomers in MS. PMID- 30300466 TI - Quantitative Analysis of Food Science Trends. PMID- 30300463 TI - Management of psychogenic non-epileptic seizures: a multidisciplinary approach. AB - The International League against Epilepsy (ILAE) proposed a diagnostic scheme for psychogenic non-epileptic seizure (PNES). The debate on ethical aspects of the diagnostic procedures is ongoing, the treatment is not standardized and management might differ according to age group. The objective was to reach an expert and stakeholder consensus on PNES management. A board comprising adult and child neurologists, neuropsychologists, psychiatrists, pharmacologists, experts in forensic medicine and bioethics as well as patients' representatives was formed. The board chose five main topics regarding PNES: diagnosis; ethical issues; psychiatric comorbidities; psychological treatment; and pharmacological treatment. After a systematic review of the literature, the board met in a consensus conference in Catanzaro (Italy). Further consultations using a model of Delphi panel were held. The global level of evidence for all topics was low. Even though most questions were formulated separately for children/adolescents and adults, no major age-related differences emerged. The board established that the approach to PNES diagnosis should comply with ILAE recommendations. Seizure induction was considered ethical, preferring the least invasive techniques. The board recommended looking carefully for mood disturbances, personality disorders and psychic trauma in persons with PNES and considering cognitive-behavioural therapy as a first-line psychological approach and pharmacological treatment to manage comorbid conditions, namely anxiety and depression. Psychogenic non epileptic seizure management should be multidisciplinary. High-quality long-term studies are needed to standardize PNES management. PMID- 30300464 TI - Evaluation of Nutritional Compositions, Bioactive Compounds, and Antioxidant Activities of Shanxi Aged Vinegars During the Aging Process. AB - : Shanxi aged vinegar (SAV) is known as famous fermented food in China. During the brewing process, a large number of nutritional substances and bioactive compounds are produced, which have beneficial effects on human body. In this study, the contents of nutritional compositions including proteins, fats, carbohydrates, organic acids, and amino acids were determined in SAV samples. The antioxidant compounds and properties of SAV with different aging time were also evaluated. The results showed that the contents of proteins, crude fats, and carbohydrates in SAV were not changed with the aging time. Moreover, Alanine was the main component of amino acids in SAV, and the total contents of amino acids were increased with the aging time. Acetic acid and lactic acid were the predominant organic acids in SAV. The contents of acetic acid and lactic acid accounted for more than 90% of the total organic acids in SAV, which were increased during the aging process of 5 years. Furthermore, total phenols, flavonoids contents, and browning index in SAV were also increased during the aging time. These antioxidant compounds showed a high correlation with the antioxidant activities of SAV measured by ferric reducing antioxidant power and 2,2'-azino-bis(3-ethylbenzthi azoline-6-sulfonic acid) assays. The contribution of polyphenolic fractions and high molecular weight melanoidins to total antioxidant activities was similar (about 49% and 48%, respectively). Our findings would provide new insights to further explore the development of new vinegar-based functional foods. PRACTICAL APPLICATION: The analysis of nutritional compositions, bioactive compounds, and antioxidant capacities in vinegars provides a theoretical basis for the function of SAV. It also provides references for further explore the development of new-type functional and healthy vinegars. PMID- 30300467 TI - Meat Color Stability of Ovine Muscles Is Related to Glycolytic Dehydrogenase Activities. AB - The relationship between glycolytic dehydrogenase, including glyceraldehyde-3 phosphate dehydrogenase (GAPDH), lactic dehydrogenase (LDH), and meat color stability was studied in this study using ovine muscle. Three different ovine muscles, including M. longissimus lumborum (LL), M. semimembranosus (SM), and M. psoas major (PM), were obtained (n = 10, respectively), and then displayed for 7 days at 4 degrees C. The LL and SM muscle had higher surface redness, higher (P < 0.05) GAPDH activity, nicotinamide adenine dinucleotide (NADH) content, and lower (P < 0.05) LDH-B activity than PM muscles during display. The PM muscle had the worst color stability and lowest NADH content. These results suggest that variation in color stability of physiologically different muscles may be affected by glycolysis dehydrogenases. Comparatively, our data showed that GAPDH may play a more important role than LDH-B to maintain meat color stability. PMID- 30300468 TI - Sensory restoration of breast reconstruction - The search for the ideal approach continues. AB - Contemporary reconstructive modalities focus on breast anatomy and attempt to reconstruct breasts that are soft, of adequate shape, size, and symmetry. However, a functional component, i.e. sensation, has largely been ignored. Flap neurotization addresses this shortcoming. While we are still in search of the ideal surgical technique to achieve this goal, a novel approach that limits nerve harvest to the sensory branch only, thus, minimizing abdominal donor-site morbidity, is presented. PMID- 30300470 TI - Identification and characterization of vaccine candidates against Hyalomma anatolicum-Vector of Crimean-Congo haemorrhagic fever virus. AB - Crimean-Congo haemorrhagic fever (CCHF) is a tick borne viral disease reported from different parts of the world. The distribution of the CCHF cases are linked with the distribution of the principal vector, Hyalomma anatolicum in the ecosystem. Presently, vector control is mainly dependent on repeated application of acaricides, results in partial efficacy and generated acaricide resistant tick strains. Amongst the different components of integrated management programme, immunization of hosts is considered as one of the sustainable component. To restrict CCHF virus spreading, use of anti-Hyalomma vaccines appears as a viable solution. Accordingly, present study was under taken to characterize and evaluate vaccine potential of two conserved molecules, ferritin2 (FER2) and tropomyosin (TPM). Silencing of the genes conferred a cumulative reduction (rejection + unable to engorge) of 61.3% in FER2 and 70.2% in TPM respectively. Furthermore, 44.2% and 72.7% reduction in engorgement weight, 63.6% and 94.9% reduction in egg masses in FER2 and TPM silenced ticks in comparison to LUC-control group was recorded. The recombinant protein, rHaFER2 was characterized as 35 kDa protein with pI of 5.84 and possesses iron binding domains. While rHaTPM is a 51kDa protein with pI of 4.94 having calcium binding domains. Immunization of cross bred calves by rHaFER2 conferred 51.7% and 51.2% protection against larvae and adults of H. anatolicum challenge infestations. While rHaTPM conferred 63.7% and 66.4% protection against larvae and adults infestations, respectively. The results were comparable with the data generated by RNAi and it clearly showed the possibility for the development of anti-hyalomma vaccine to manage CCHF virus and Theileria annulata infection in human and animals. PMID- 30300469 TI - Soft, Skin-Interfaced Microfluidic Systems with Wireless, Battery-Free Electronics for Digital, Real-Time Tracking of Sweat Loss and Electrolyte Composition. AB - Sweat excretion is a dynamic physiological process that varies with body position, activity level, environmental factors, and health status. Conventional means for measuring the properties of sweat yield accurate results but their requirements for sampling and analytics do not allow for use in the field. Emerging wearable devices offer significant advantages over existing approaches, but each has significant drawbacks associated with bulk and weight, inability to quantify volumetric sweat rate and loss, robustness, and/or inadequate accuracy in biochemical analysis. This paper presents a thin, miniaturized, skin interfaced microfluidic technology that includes a reusable, battery-free electronics module for measuring sweat conductivity and rate in real-time using wireless power from and data communication to electronic devices with capabilities in near field communications (NFC), including most smartphones. The platform exploits ultrathin electrodes integrated within a collection of microchannels as interfaces to circuits that leverage NFC protocols. The resulting capabilities are complementary to those of previously reported colorimetric strategies. Systematic studies of these combined microfluidic/electronic systems, accurate correlations of measurements performed with them to those of laboratory standard instrumentation, and field tests on human subjects exercising and at rest establish the key operational features and their utility in sweat analytics. PMID- 30300471 TI - Antidiabetic Effect of Abextide, a Long-Acting Exendin-4 Analogue in Cynomolgus Monkeys. AB - Abextide, synthesized by conjugating an albumin-binding moiety-truncated Evans blue-to glucagon-like peptide 1 receptor (GLP-1R) agonist exendin-4, shows extended drug release and enhanced hypoglycemic effect in diabetic mice. The aim of this study is to evaluate the pharmacodynamics of Abextide in nonhuman primates. Two batches of elderly cynomolgus monkeys with naturally occurring diabetes are used for this study. During the whole experiment period, no abnormalities such as swelling at the injection site, lethargy, or hypoglycemia are observed in all animals. The monkeys in the Abextide group lose appetite after drug administration and then recover over time. In the single dose treatment, at day 1 and day 3 after treatment, decreased plasma glucose level is observed in the Abextide-treated group but not in placebo or Albiglutide-treated group. For monkeys that receive two doses of drug, the blood glucose level in all subjects in Abextide group decreases rapidly upon drug administration and return to a plateau by day 3. A similar pattern of response is seen after the second dose administration. The delayed drug release and hypoglycemic effect of Abextide make it potentially useful as an antidiabetic drug for weekly subcutaneous administration. PMID- 30300472 TI - Discordance in risk factors for the progression of diabetic retinopathy and diabetic nephropathy in patients with type 2 diabetes mellitus. AB - AIMS/INTRODUCTION: We aimed to investigate whether there are differences in the risk factors or markers for the progression of diabetic retinopathy (DR) and diabetic nephropathy (DN) in type 2 diabetes mellitus. MATERIALS AND METHODS: We carried out a 3-year retrospective cohort study of 604 patients with type 2 diabetes mellitus. The outcomes were the progression of DR (worsening of the DR stage) and DN (an estimated glomerular filtration rate decline >12%) at the 3 year follow up. The mean hemoglobin A1c (HbA1c) level and HbA1c variability (HbA1c-VAR) were calculated. RESULTS: The mean HbA1c and HbA1c-VAR levels were higher in the DR progressors (n = 67) than in the DR non-progressors (n = 537). The mean HbA1c was a significant predictor for DR progression independent of the duration of diabetes and HbA1c-VAR levels. The urine albumin-to-creatinine ratio at baseline and HbA1c-VAR levels were higher in the DN progressors (n = 34) than in the DN non-progressors (n = 570). The triglyceride to high-density lipoprotein cholesterol ratio at baseline tended to be higher in the DN progressors than in the DN non-progressors. HbA1c-VAR levels and the triglyceride-to-high-density lipoprotein cholesterol ratio were significant predictors for DN progression independent of estimated glomerular filtration rate and the urine albumin-to creatinine ratio. CONCLUSIONS: Average glycemia was significantly associated with progression of DR, whereas glycemic variability and dyslipidemia were significantly associated with progression of DN in type 2 diabetes mellitus. PMID- 30300473 TI - One-Step Synthesis of Iodinated Polypyrrole Nanoparticles for CT Imaging Guided Photothermal Therapy of Tumors. AB - Theranostic materials are of great significance to a personalized precise medicine. However, conventional theranostic agents are mainly fabricated by combining presynthesized independent imaging probes and therapeutic agents, suffering from multiple synthesis procedures, poor morphological control, and time/reagent-consuming process. Herein, iodinated polypyrrole (I-PPy) nanoparticles are fabricated via a one-step synthesis strategy combining chemical oxidation and iodination for computed tomography (CT) imaging-guided photothermal therapy. Iodic acid with a high standard electrode potential enables the chemical oxidation polymerization of pyrrole monomers. Meanwhile, the iodination of PPy induced by the corresponding reduction product I2 takes place during the polymerization process to generate I-PPy nanoparticles. The prepared I-PPy nanoparticles possess a uniform size, excellent colloidal stability, intense near infrared absorption, strong X-ray attenuation ability, and favorable biocompatibility. The as-synthesized I-PPy nanoparticles not only guarantee remarkable contrast-enhanced CT imaging of blood pool and tumors, but also realize effective tumor suppression in vitro and in vivo by I-PPy nanoparticles mediated CT imaging-guided photothermal therapy. To the best of the authors' knowledge, it is the first time that multifunctional PPy nanoparticles are fabricated through a one-step synthesis process. The proposed strategy opens up a new way for the fabrication of high-performance theranostic agents via a one-step strategy under mild conditions. PMID- 30300474 TI - The association of childhood sleep problems with the prevalence of traumatic dental injury in schoolchildren. AB - BACKGROUND/AIM: Sleep quality exerts an influence on attention level and motor skills and is associated with accidental injuries in children. The aim of this study was to evaluate the association between traumatic dental injury and sleep behaviour in children. MATERIAL AND METHODS: A cross-sectional study was conducted in a small city in southern Brazil with a representative sample of schoolchildren aged 8-10 years (n = 537). Weight and height were measured, and examinations were performed for the determination of clinical occlusion and traumatic dental injury. The parents answered the Sleep Behaviour Questionnaire and questions addressing socio-demographic characteristics. RESULTS: The prevalence of traumatic dental injury was 22% (95% CI: 19-26) and was higher among children who woke three to four times per night (PR = 3.30; 95% CI: 2.47 4.39), those who fell asleep in the parental bed (PR = 1.41; 95% CI: 1.09-1.83), those who were not in a good mood on waking up in the morning (PR = 1.30; 95% CI: 1.02-1.65), those who became sleepy while sitting and/or studying (PR = 1.57; 95% CI: 1.09-2.24) and while watching TV (PR = 1.41; 95% CI: 1.0005-1.97) and those who had bad dreams (PR = 1.35; 95% CI: 1.04-1.76). The Poisson multiple regression model with a multilevel approach revealed that the prevalence of traumatic dental injury was 1.51-fold higher among children with daytime drowsiness (PR = 1.51; 95% CI: 1.11-2.04) after adjusting for socio-demographic, occlusal and anthropometric variables. CONCLUSION: Sleep problems were associated with a higher prevalence of traumatic dental injury among the children analysed. PMID- 30300475 TI - Thermoforming method to effectively maintain mouthguard thickness: Effect of moving the model position just before vacuum formation. AB - BACKGROUND/AIMS: Mouthguards can reduce the risk of sports-related injuries but the sheet material and thickness have a large effect on their efficacy and safety. The aim of this study was to investigate the effect of the thermoforming technique that moves the model position just before vacuum formation. MATERIALS AND METHODS: Ethylene vinyl acetate sheets of 4.0-mm thickness and a vacuum forming machine were used. The working model was placed with its anterior rim positioned 40 mm from the front of the forming table. Three forming conditions were compared: (a) The sheet was formed when it sagged 15 mm at the top of the post under normal conditions (control); (b) the sheet frame was lowered to and heated at 50 mm from the level of ordinary use, and the sheet was formed when it sagged 15 mm (LH); and (c) the sheet frame at the top of the post was lowered and covered on the model when it sagged 15 mm. Subsequently, the rear side of the model was pushed to move it forward 20 mm, and it was then formed (MP). Sheet thickness after fabrication was determined for the incisal edge, labial surface, and buccal surface using a specialized caliper accurate to 0.1 mm. Thickness differences among forming conditions were analyzed by one-way ANOVA and Bonferroni's multiple comparison tests. RESULTS: A significant difference was observed for all measurement points, and the thickness after formation increased in the order of control, LH, and MP. Particularly on the labial surface, MP was able to yield about 1.7 times the thickness (about 3.1 mm) of the control. CONCLUSION: The forming method of moving the model forward just before vacuum formation was effective for suppressing the mouthguard thickness reduction, which is capable of securing the labial thickness at 3 mm or more with a single layer.

AB - Diabetic foot ulceration has been a serious issue over the past decades in Asia, causing economic and social problems. Therefore, it is important to identify and reduce the risk factors of diabetic foot. Cigarette smoking has been reported to be associated with diabetes and its macrovascular complications, but the relationship between smoking and diabetic foot ulcers is still unclear. In the present review, we summarize the effects of cigarette smoking on diabetic foot ulcers with respect to peripheral neuropathy, vascular alterations and wound healing. One underlying mechanism of these impacts might be the smoking-induced oxidative stress inside the cells. At the end of this review, the current mainstream therapies for smoking cessation are also outlined. We believe that it is urgent for all diabetic patients to quit smoking so as to reduce their chances of developing foot ulcers and to improve the prognosis of diabetic foot ulcers.

AB - Das Down-Syndrom (DS) ist mit einer Inzidenz von 1 : 700 aller Geburten nicht selten und mit diversen Erkrankungen unterschiedlicher Organsysteme assoziiert. Zu den schwerwiegenden Erkrankungen zahlen Herzfehler und Leukamie. Letztere zeigt sich im Neugeborenenalter und geht nicht immer in eine klassische myeloische Leukamie uber (transiente myeloproliferative Erkrankung). Dermatologisch bilden die Neugeborenen Pusteln/Vesikulopusteln, die bei DS nicht nur an typische Neugeborenenexantheme und Infektionen, sondern auch an die transiente myeloproliferative Erkrankung denken lassen sollten. Die meisten Dermatosen jedoch sind benigner Natur und umfassen im Wesentlichen Verhornungsstorungen, die sich als Xerosis, Keratosis pilaris, Lichenifikation und Ichthyosis vulgaris zeigen. Typisch, aber nicht spezifisch, ist auch die palmare Vierfingerfurche. Die Patienten neigen haufig zu Follikulitiden, die aufgrund einer Elastolyse in eine Anetodermie ubergehen. Die bekannte Immundysbalance erklart das Auftreten von Autoimmunerkrankungen, die sich an der Haut als Alopecia areata und Vitiligo manifestieren. Als typische Hautveranderungen bei DS zahlen zudem Elastosis perforans serpiginosa, Syringome, Milien-ahnliche Calcinosis cutis (Milia-like calcinosis cutis) und Multiple eruptive Dermatofibrome.

PMID- 30300491 TI - Dermatological aspects of the S2k guidelines on Down syndrome in childhood and adolescence. AB - With an incidence of 1 in 700 births, Down syndrome (DS) is not an uncommon condition. It is associated with various disorders of different organ systems. Serious disorders include cardiac defects and leukemia. With an onset during the newborn period, the latter does not always progress to classic myeloid leukemia (transient myeloproliferative disorder). Skin manifestations in newborns include pustules/vesiculopustules. In individuals with DS, such lesions should not only prompt suspicion for typical neonatal rashes and infections but also for transient myeloproliferative disorder. However, most dermatoses are benign. They essentially comprise disorders of keratinization that present as xerosis, keratosis pilaris, lichenification, and ichthyosis vulgaris. Also typical but not specific is the four-finger palmar crease (simian crease). Patients frequently develop folliculitides, which - due to elastolysis - subsequently progress to anetoderma. The known immune disturbance in DS patients explains the occurrence of autoimmune diseases such as alopecia areata and vitiligo. Typical skin conditions associated with DS include elastosis perforans serpiginosa, syringomas, milia-like calcinosis cutis, and multiple eruptive dermatofibromas.

AB - Hymenoptera venom allergy is the most common cause of anaphylactic reactions in adults. In children, it is the second most common cause after food-related anaphylaxis. Such reactions are primarily due to stings by honeybees (Apis) and certain social wasps (Vespula vulgaris and Vespula germanica in particular). Especially in adults, stings are frequently associated with severe anaphylaxis. Established diagnostic methods including molecular tests allow for greater success rates in terms of determining the insect actually responsible for triggering the anaphylactic reaction. Sensitization to both venoms, or a history of systemic sting reaction without any evidence of sensitization, complicate the decision regarding treatment. Venom immunotherapy (VIT) is a safe and effective causal treatment. PMID- 30300501 TI - An Early History of Medical Translation.

AB - MXenes, a newly intriguing family of 2D materials, have recently attracted considerable attention owing to their excellent properties such as high electrical conductivity and mobility, tunable structure, and termination groups. Here, the Ti3 C2 Tx MXene is incorporated into the perovskite absorber layer for the first time, which aims for efficiency enhancement. Results show that the termination groups of Ti3 C2 Tx can retard the crystallization rate, thereby increasing the crystal size of CH3 NH3 PbI3 . It is found that the high electrical conductivity and mobility of MXene can accelerate the charge transfer. After optimizing the key parameters, 12% enhancement in device performance is achieved by 0.03 wt% amount of MXene additive. This work unlocks opportunities for the use of MXene as potential materials in perovskite solar cell applications. PMID- 30300504 TI - Biochemical characterization of the minimal domains of an iterative eukaryotic polyketide synthase. AB - Iterative type I polyketide synthases (PKS) are megaenzymes essential to the biosynthesis of an enormously diverse array of bioactive natural products. Each PKS contains minimally three functional domains, beta-ketosynthase (KS), acyltransferase (AT), and acyl carrier protein (ACP), and a subset of reducing domains such as ketoreductase (KR), dehydratase (DH), and enoylreductase (ER). The substrate selection, condensation reactions, and beta-keto processing of the polyketide growing chain are highly controlled in a programmed manner. However, the structural features and mechanistic rules that orchestrate the iterative cycles, processing domains functionality, and chain termination in this kind of megaenzymes are often poorly understood. Here, we present a biochemical and functional characterization of the KS and the AT domains of a PKS from the mallard duck Anas platyrhynchos (ApPKS). ApPKS belongs to an animal PKS family phylogenetically more related to bacterial PKS than to metazoan fatty acid synthases. Through the dissection of the ApPKS enzyme into mono- to didomain fragments and its reconstitution in vitro, we determined its substrate specificity toward different starters and extender units. ApPKS AT domain can effectively transfer acetyl-CoA and malonyl-CoA to the ApPKS ACP stand-alone domain. Furthermore, the KS and KR domains, in the presence of Escherichia coli ACP, acetyl-CoA, and malonyl-CoA, showed the ability to catalyze the chain elongation and the beta-keto reduction steps necessary to yield a 3 hydroxybutyryl-ACP derivate. These results provide new insights into the catalytic efficiency and specificity of this uncharacterized family of PKSs. PMID- 30300505 TI - Molecular recognition of the beta-glucans laminarin and pustulan by a SusD-like glycan-binding protein of a marine Bacteroidetes. AB - Marine bacteria catabolize carbohydrate polymers of algae, which synthesize these structurally diverse molecules in ocean surface waters. Although algal glycans are an abundant carbon and energy source in the ocean, the molecular details that enable specific recognition between algal glycans and bacterial degraders remain largely unknown. Here we characterized a surface protein, GMSusD from the planktonic Bacteroidetes-Gramella sp. MAR_2010_102 that thrives during algal blooms. Our biochemical and structural analyses show that GMSusD binds glucose polysaccharides such as branched laminarin and linear pustulan. The 1.8 A crystal structure of GMSusD indicates that three tryptophan residues form the putative glycan-binding site. Mutagenesis studies confirmed that these residues are crucial for laminarin recognition. We queried metagenomes of global surface water datasets for the occurrence of SusD-like proteins and found sequences with the three structurally conserved residues in different locations in the ocean. The molecular selectivity of GMSusD underscores that specific interactions are required for laminarin recognition. In conclusion, our findings provide insight into the molecular details of beta-glucan binding by GMSusD and our bioinformatic analysis reveals that this molecular interaction may contribute to glucan cycling in the surface ocean.

Objective: To assess the effect of parathyroidectomy on fat mass, glucose and lipid metabolism. Design, patients, interventions, main outcome measures: 119 patients previously randomized to observation (OBS; n = 58) or parathyroidectomy (PTX; n = 61) within the Scandinavian Investigation of Primary Hyperparathyroidism (SIPH) trial, an open randomized multicenter study, were included. Main outcome measures for this study were the differences in fat mass, markers for lipid and glucose metabolism between OBS and PTX 5 years after randomization. Results: In the OBS group, total cholesterol (Total-C) decreased from mean 5.9 (+/-1.1) to 5.6 (+/-1.0) mmol/L (P = 0.037) and LDL cholesterol (LDL-C) decreased from 3.7 (+/-1.0) to 3.3 (+/-0.9) mmol/L (P = 0.010). In the PTX group, the Total-C and LDL-C remained unchanged resulting in a significant between-group difference over time (P = 0.013 and P = 0.026, respectively). This difference was driven by patients who started with lipid-lowering medication during the study period (OBS: 5; PTX: 1). There was an increase in trunk fat mass in the OBS group, but no between-group differences over time. Mean 25(OH) vitamin D increased in the PTX group (P < 0.001), but did not change in the OBS group. No difference in parameters of glucose metabolism was detected. Conclusion: In mild PHPT, the measured metabolic and cardiovascular risk factors were not modified by PTX. Observation seems safe and cardiovascular risk reduction should not be regarded as a separate indication for parathyroidectomy based on the results from this study. PMID- 30300534 TI - Adherence and long-term growth outcomes: results from the easypodTM connect observational study (ECOS) in paediatric patients with growth disorders AB - Objective: The easypod connect observational study (ECOS) assessed treatment adherence among paediatric patients receiving growth hormone (GH) via the easypod electronic injection device. Design: ECOS was an open-label, observational, longitudinal study conducted in 24 countries between 2010 and 2016, enrolling children treated with GH. Methods: The primary endpoint was the rate of treatment adherence during 5 years of follow-up. Impact of adherence on growth outcomes was assessed using Spearman's product-moment correlations. Results and conclusions: Overall, 1190 patients had easypod data available for >=3 months; most patients had GH deficiency (75%); 606 of these patients were GH naive at baseline. Over the first year of monitoring, the median rate of adherence was 93.7% among patients overall and >93.0% in GH-naive patients, irrespective of the treatment indication. Clinically meaningful improvements in growth rates were observed after 1 year of treatment across all GH indications. Adherence decreased with increasing treatment duration, but the overall median adherence rate remained high after 3 years of follow-up: 87.2% (n = 409), 75.5% after 4 years (n = 143) and 70.2% after 5 years (n = 43). Statistically significant correlations between adherence and 1-year change in height standard deviation score (P < 0.001 for patients overall) and height velocity (P < 0.001) were observed. Conclusions: ECOS produced accurate, real-time adherence data in a large population of GH treated children over 5 years of follow-up. Using the easypod connect system, physicians can potentially identify patients with inadequate adherence and poor response to treatment, enabling them to take appropriate action to help them maximise the benefits of GH treatment. PMID- 30300533 TI - Post-chemotherapy serum anti-Mullerian hormone level predicts ovarian function recovery AB - In the era of precision medicine, the prediction of ovarian function recovery from chemotherapy-induced amenorrhoea using feasible biological markers may be helpful to optimise the treatment strategy for young patients with hormone receptor-positive breast cancer. The purpose of this study was to investigate the accuracy of post-chemotherapy biological markers for predicting the recovery of ovarian function in breast cancer patients of the ASTRRA trial, with chemotherapy induced amenorrhoea. Using data of 82 participants from a single institution in the ASTRRA trial, the post-chemotherapy serum levels of the anti-Mullerian hormone (AMH), oestradiol, inhibin B and other clinical factors associated with chemotherapy-induced amenorrhoea were evaluated. Recovery of ovarian function was defined by the resumption of menstruation manifested by vaginal bleeding. Fifty two patients regained menstruation within 55 months after enrolment. In univariate analysis, <40 years of age (P = 0.009), oestradiol >=37 pg/mL (P = 0.003) or AMH >=800 pg/mL (P = 0.026) were associated with recovery of menstruation. On multivariate analysis, oestradiol (hazard ratio: 3.171, 95% CI: 1.306-7.699, P = 0.011) and AMH (hazard ratio: 2.853, 95% CI: 1.011-8.046, P = 0.048) remained as significant independent predictors for resumption of menstruation. The diagnostic accuracy of age, oestradiol and AMH in predicting the resumption of menstruation was 38.3, 23.3 and 86.7%, respectively. In conclusion, post-chemotherapy AMH level might be a relatively accurate predictor of the recovery of ovarian function, presented by resumption of menstruation in breast cancer patients with chemotherapy-induced amenorrhoea PMID- 30300535 TI - Behavioural phenotyping, learning and memory in young and aged growth hormone releasing hormone-knockout mice AB - Background: Growth hormone-releasing hormone (GHRH) plays an important role in brain functions. The aim of this study was to examine cognitive functions and emotional behaviour in a mouse model of isolated GH deficiency due to bi-allelic ablation of the GHRH gene (GHRH knockout, GHRHKO). Methods: Learning, memory and emotional behaviour were evaluated using a series of validated tests (Morris water maze, eight-arm radial maze, open field, elevated plus maze test, forced swim tests) in 2-, 5- and 12-month-old male mice either homozygous (-/-) or heterozygous (+/-) for the GHRHKO allele. Results: Compared with age-matched +/- mice, -/- mice showed decreased cognitive performance in Morris water maze and eight-arm radial maze tests. By comparing the effects of aging in each genotype, we observed an age-related impairment in test results in +/- mice, while in -/- mice a significant decline in cognitive function was found only in 12 months compared with 2-month-old mice, but no difference was found between 5 months old vs 2 months old. -/- mice showed increased exploration activity compared to age matched +/- controls, while both strains of mice had an age-related decrease in exploration activity. When evaluated through open field, elevated plus maze and forced swim tests, -/- mice demonstrated a decrease in anxiety and depression related behaviour compared to age-matched +/- controls. Conclusions: Our results suggest that homozygous ablation of GHRH gene is associated with decreased performance in learning and memory tests, possibly linked to increased spontaneous locomotor activity. In addition, we observed an age-related decline in cognitive functions in both genotypes. PMID- 30300536 TI - Improved salivary cortisol rhythm with dual-release hydrocortisone AB - Introduction and Aim: The purpose of replacement therapy in adrenal insufficiency (AI) is mimicking endogenous cortisol levels as closely as possible: dual release hydrocortisone (DR-HC) has been introduced to replicate the circadian cortisol rhythm. Multiple daily saliva collections could be used to assess the cortisol rhythm during real life: our aim was to study the salivary cortisol profile in AI. Materials and Methods: We prospectively evaluated, in an observational study, 18 adult outpatients with AI (11 primary and 7 secondary AI), switched from conventional treatment (conv-HC, 25 mg/day) to the same dose of DR-HC. We collected six samples of saliva in a day, measuring cortisol (F) and cortisone (E) with LC-MS/MS. Forty-three matched healthy subjects served as controls. Results: F levels were similar in the morning (and higher than controls) in patients treated with conv-HC or DR-HC; otherwise F levels and exposure were lower in the afternoon and evening in patients with DR-HC, achieving a cortisol profile closer to healthy controls. Daily cortisol exposure, measured with area under the curve, was lower with DR-HC. Morning F and E presented sensitivity and specificity >90% to diagnose AI (respectively threshold of 3 and 9.45 nmol/L). Total cholesterol and HbA1c levels reduced with DR-HC. Conclusions: Salivary cortisol daily curve could be used as a new tool to assess the cortisol profiles in patients treated with conv-HC and DR-HC. A lower daily cortisol exposure was achieved with DR-HC (despite the same HC dose), especially in the afternoon evening. PMID- 30300537 TI - Circulating MIR148A associates with sensitivity to adiponectin levels in human metabolic surgery for weight loss AB - Objective: We sought to discover secreted biomarkers to monitor the recovery of physiological adiponectin levels with metabolic surgery, focusing on epigenetic changes that might predict adiponectin function. Design: We conducted a prospective observational study of patients undergoing metabolic surgery by Roux en-Y Gastric Bypass (RYGB) for weight loss in a single center (IRB GHS # 1207 27). Methods: All patients (n = 33; 27 females; 6 males) signed informed consent. Metabolites, adiponectin and MIR148A were measured in fasting plasma. We followed MIQE for transcript profiles. Results: Patients lost on average 47 +/- 12% excess BMI (%EBMI) after 12 weeks. Adiponectin pre, post or delta (post minus pre) did not correlate with %EBMIL. A decrease in adiponectin following weight loss surgery was observed in a subset of patients, chi-square test of independence rejects the null hypotheses that the liver DNA methyltransferase 1 (DNMT1) and delta adiponectin are independent (chi-square statistics chi2 = 6.9205, P = 0.00852, n = 33), as well as MIR148A and delta adiponectin are independent (chi square statistics chi2 = 9.6823, P = 0.00186, n = 33). The presence of plasma MIR148A allows identification of patients that appear to be adiponectin insensitive at baseline. Conclusion: We combined the presence of plasma MIR148A, the concentration of total adiponectin and the expression of DNA methyltransferase 1 (DNMT1) in liver biopsy tissue to identify patients with non physiological adiponectin. Weight loss and physical activity interventions complemented with the new method presented here could serve to monitor the physiological levels of adiponectin, thought to be important for long-term weight loss maintenance. PMID- 30300538 TI - The effect of obesity and dietary habits on oxidative stress in Hashimoto's thyroiditis AB - Objective: Increased oxidative stress has been described in patients with Hashimoto's thyroiditis (HT). The aim of the present study was to investigate whether high oxidative stress is further influenced by obesity and dietary habits in euthyroid women with HT. Methods: Two hundred eighteen consecutive euthyroid women with HT were studied and separated in two groups; 102 with thyroxine replacement and 114 without. For the evaluation of oxidative stress, total lipid peroxide levels in serum (TOS) were measured and recoded as 'high TOS' vs 'medium/low TOS'. The type of food and consumption frequency were recorded. Two binary variables were considered; normal vs low fruit consumption and daily vs sporadic vegetable consumption. Results: 'High TOS' was more frequent in women under thyroxine replacement (31.4% vs 14.7%, OR = 2.7, 95% CI: 1.4-5.2). The prevalence of 'high TOS' was higher among overweight/obese women compared to women with normal BMI (30.4% vs 12.5%, OR = 3.1, 95% CI: 1.5-6.4). Low fruit consumption was associated with increased 'high TOS' prevalence (30.6% vs 12.9%, OR = 3.0, 95% CI: 1.4-6.2). Sporadic vegetable consumption was associated with increased 'high TOS' prevalence compared to daily consumption (29.9% vs 13.5%, OR = 2.7, 95% CI: 1.3-5.7). The examined risk factors were independent and additive in their effect on TOS. At least three risk factors had to be concomitantly present for the likelihood of 'high TOS' to be significantly elevated. Conclusions: Oxidative stress is increased in women with HT under thyroxine replacement. Nevertheless, normal BMI, daily fruit and vegetable consumption, all contribute in maintaining oxidative stress at low levels. PMID- 30300539 TI - The RET C611Y mutation causes MEN 2A and associated cutaneous AB - Background: Cutaneous lichen amyloidosis (CLA) has been reported in some multiple endocrine neoplasia type 2A (MEN 2A) families affected by specific germline RET mutations C634F/G/R/W/Y or V804M, as a characteristic of the clinical manifestation in 'MEN 2A with CLA', one of four variants of MEN 2A, which was strictly located in the scapular region of the upper back. Patient Findings: This study reports a large south-eastern Chinese pedigree with 17 individuals carrying the MEN 2A-harboring germline C611Y (c.1832G>A) RET mutation by Sanger sequencing. One individual presented MEN 2A-related clinical features, including typical CLA in the interscapular region; another individual exhibited neurological pruritus and scratching in the upper back but lacked CLA skin lesions. Both subjects presented with CLA or pruritic symptoms several years before the onset of medullary thyroid carcinoma (MTC) and/or pheochromocytoma. The remaining 15 RET mutation carriers did not exhibit CLA; of these, one presented with MTC and pheochromocytoma, nine with MTC only, two with elevated serum calcitonin and three younger subjects with normal serum calcitonin levels. This family's clinical data revealed a later diagnosis of MTC (mean age, 45.9 (range: 23-73) years), a lower penetrance of pheochromocytoma (2/17, 11.8%) and CLA (1/17, 5.9%). However, no hyperparathyroidism and Hirschsprung disease were reported in this family. Summary and Conclusions: This is the first description of a family with MEN 2A-related CLA due to a germline RET C611Y mutation, which might exhibit a novel and diversified genotype-phenotype spectrum in MEN 2A. PMID- 30300540 TI - Vitamin D measurement and effect on outcome in a cohort of patients with heart failure AB - Objectives: The aims of this paper were to evaluate the levels of Vitamin D (VitD) in patients with heart failure (HF), compared to a control group, to assess the effects of VitD on HF outcome and to compare VitD measurement between LIAISON immunoassay and HPLC-MS-MS methods in this population. Design and Methods: We collected clinical, biochemical and outcome data from 247 patients with HF and in a subgroup of 151 patients, we measured VitD both with LIAISON and HPLC-MS-MS. Results: HF patients had statistically lower 25OHD levels (45.2 +/- 23.7 nmol/L vs 58.2 +/- 24.0 nmol/L, P < 0.001) and a statistically higher prevalence of VitD insufficiency (61.1% vs 39.5%, P < 0.001) and deficiency (24.7% vs 6.6%, P < 0.001), compared to healthy controls. There was a significant inverse relationship between baseline 25OHD and risk of HF-related death, with a HR of 0.59 (95% CI 0.37-0.92, P = 0.02), confirmed in a multivariate adjusted analysis. Kaplan-Meier survival analyses showed that VitD insufficiency was associated with reduced survival in HF patients (log rank P = 0.017). There was a good agreement between LIAISON and HPLC-MS-MS (Cohen's kappa coefficient 0.70), but the prevalence of VitD insufficiency was significantly higher with the former compared to the latter method (58.3%, n = 88 vs 55.6%, n = 84, P < 0.001). LIAISON underestimated the 25OHD levels and showed a mean relative bias of 0.739% with 95% of limits of agreement (-9.00 to +7.52%), when compared to HPLC MS-MS. Conclusions: 25OHD levels adequately measured by HPLC-MS-MS showed to be low in HF population and to be correlated with HF-related risk of death. PMID- 30300541 TI - Serum anti-Mullerian hormone predicts ovarian response in (Macaca fascicularis) monkeys AB - AMH as a promising predictor of ovarian response has been studied extensively in women undergoing assisted reproductive technology treatment, but little is known about its prediction value in monkeys undergoing ovarian stimulation. In the current study, a total of 380 cynomolgus monkeys ranging from 5 to 12 years received 699 ovarian stimulation cycles. Serum samples were collected for AMH measure with enzyme-linked immunosorbent assay. It was found that serum AMH levels were positive correlated with the number of retrieved oocytes (P < 0.01) in the first, second and third stimulation cycles. In the first cycles, area under the curve (ROCAUC) of AMH is 0.688 for low response and 0.612 for high response respectively, indicating the significant prediction values (P = 0.000 and P = 0.005). The optimal AMH cutoff value was 9.68 ng/mL for low ovarian response and 15.88 ng/mL for high ovarian response prediction. In the second stimulation cycles, the significance of ROCAUC of AMH for high response rather than the low response was observed (P = 0.001 and P = 0.468). The optimal AMH cutoff value for high ovarian response was 15.61 ng/mL. In the third stimulation cycles, AMH lost the prediction value with no significant ROCAUC. Our data demonstrated that AMH, not age, is a cycle-dependent predictor for ovarian response in form of oocyte yields, which would promote the application of AMH in assisted reproductive treatment (ART) of female cynomolgus monkeys. AMH evaluation would optimize candidate selection for ART and individualize the ovarian stimulation strategies, and consequentially improve the efficiency in monkeys. PMID- 30300542 TI - Hydrogen-Bond Assembly of Poly(vinyl alcohol) and Polyhexamethylene Guanidine for Nonleaching and Transparent Antimicrobial Films. AB - The combination of transparency, antimicrobial activities, nonleaching of antimicrobial component and green preparation for poly(vinyl alcohol) (PVA) films is of importance for practical applications in industry. However, until now it remains a challenge. Herein, a facile antimicrobial PVA films containing polyhexamethylene guanidine (PHMG) is reported via a green solution casting method. Such PVA films show high transparency of 91%, above 99.99% of antimicrobial rates against Escherichia coli and Staphylococcus aureus, and nonleaching characteristic of PHMG due to the hydrogen-bond (H-bond) interaction between PHMG and PVA. The thermal stability and mechanical properties of the PVA films are further improved compared to neat PVA film. These antimicrobial films are expected to find promising applications in tissue engineering and packaging fields, which opens up a methodology to prepare nonleaching antimicrobial polymeric materials via H-bond. PMID- 30300543 TI - Accelerating QM/MM Free Energy Computations via Intramolecular Force Matching. AB - The calculation of free energy differences between levels of theory has numerous potential pitfalls. Chief among them is the lack of overlap, i.e., ensembles generated at one level of theory (e.g., "low") not being good approximations of ensembles at the other (e.g., "high"). Numerous strategies have been devised to mitigate this issue. However, the most straightforward approach is to ensure that the "low" level ensemble more closely resembles that of the "high". Ideally, this is done without increasing computational cost. Herein, we demonstrate that by reparametrizing classical intramolecular potentials to reproduce high level forces (i.e., force matching) configurational overlap between a "low" (i.e., classical) and "high" (i.e., quantum) level can be significantly improved. This procedure is validated on two test cases and results in vastly improved convergence of free energy simulations. PMID- 30300544 TI - Synthesis of Chiral Carbo-Nanotweezers for Enantiospecific Recognition and DNA Duplex Winding in Cancer Cells. AB - Targeting the DNA of tumor cells with small molecules may offer effective clinical strategies for transcriptional inhibition. We unveil synthesis and characterization of ~20 nm chiral carbon nanoparticles for enantiospecific recognition of DNA. Our approach inculcates chirality in carbon nanoparticles by controlled tethering of minor groove binders, i.e., Troger's base (TB). The chiral particles positively enriched the cellular nucleus in MCF-7 breast cancer cells, irrespective of the TB asymmetry tethered on the particle surface, but negatively induced chiral carbon nanoparticles exhibited improved efficiency at inhibiting cell growth. Further studies indicated that these chiral particles act as nanotweezers to perturb the genomic DNA and induce apoptosis cascade in cancer cells. PMID- 30300545 TI - Lipid-Polymer Bilaminar Oxygen Nanobubbles for Enhanced Photodynamic Therapy of Cancer. AB - Hypoxia in solid tumors may be a hindrance to effective treatments of tumors in achieving their therapeutic potential, especially for photodynamic therapy (PDT) which requires oxygen as the supplement substrate. Oxygen delivery using perfluorocarbon emulsions or lipid oxygen microbubbles has been developed as the agents to supply endogenous oxygen to fuel singlet oxygen generation in PDT. However, such methods suffer from premature oxygen release and storage issues. To address these limitations, we designed lipid-polymer bilaminar oxygen nanobubbles with chlorin e6 (Ce6) conjugated to the polymer shell as a novel oxygen self supplement agent for PDT. The resultant nanobubbles possessed excellent stability to reduce the risk of premature oxygen release and were stored as freeze-dried powders to avoid shelf storage issues. In vitro and in vivo experimental results demonstrated that the nanobubbles exhibited much higher cellular uptake rates and tumor targeting efficiency compared to free Ce6. Using the oxygen nanobubbles for PDT, a significant enhancement of therapeutic efficacy and survival rates was achieved on a C6 glioma-bearing mice model with no noticeable side effects, owing to the greatly enhanced singlet oxygen generation powered by oxygen encapsulated nanobubbles. PMID- 30300546 TI - Metabolic Engineering of Escherichia coli for High Yield Production of Succinic Acid Driven by Methanol. AB - Methanol is increasingly becoming an attractive carbon feedstock for the production of various biochemicals due to its high abundance and low price. In this study, when methanol assimilation module was introduced into succinic acid producing Escherichia coli by employing the NAD-dependent methanol dehydrogenase from Bacillus methanolicus and ribulose monophosphate pathway from different donor organisms, succinic acid yield was increased from 0.91 +/- 0.08 g/g to 0.98 +/- 0.11 g/g with methanol as an auxiliary substrate under the anaerobic fermentation. Further 13C-labeling experiments showed that the recombinant strain successfully converted methanol into succinic acid, as the carbon atom of carboxyl group in succinic acid was labeled by 13C. It was found that the NADH generated by methanol oxidation would benefit succinate production, as the NADH/NAD+ ratio in vivo was decreased from 0.67 to 0.45 in the engineered strain, indicating that the efficiency of succinic acid synthesis was significantly improved when driven by methanol. This study represents a successful case for the development of reducing chemical production using methanol as an auxiliary substrate. PMID- 30300547 TI - Successive Surface Reactions on Hydrophilic Silica for Modified Magnetic Nanoparticle Attachment Probed by Sum-Frequency Generation Spectroscopy. AB - Successive surface reactions on hydrophilic silica substrates were designed and performed to immobilize ethanolamine-modified magnetic ferrite-based nanoparticle (NP) for surface characterization. The various surfaces were monitored using sum frequency generation (SFG) spectroscopy. The surface of the hydrophilic quartz substrate was first converted to a vinyl-terminated surface by utilizing a silanization reaction, and then, the surface functional groups were converted to carboxylic-terminated groups via a thiol-ene reaction. The appearance and disappearance of the vinyl (?CH2) peak at ~2990 cm-1 in the SFG spectra were examined to confirm the success of the silanization and thiol-ene reactions, respectively. Acyl chloride (-COCl) formation from carboxy (-COOH) functional group was then performed for further attachment of magnetic amine-functionalized magnesium ferrite nanoparticles (NPs) via amide bond formation. The scattered NPs attached on the modified silica substrate was then used to study the changes in the spectral profile of the ethanolamine modifier of the NPs for in situ lead(II) (Pb2+) adsorption at the solid-liquid interface using SFG spectroscopy. However, due to the limited number of NPs attached and sensitivity of SFG spectroscopy toward expected change in the modifier spectroscopically, no significant change was observed in the SFG spectrum of the modified silica with magnetic NPs during exposure to Pb2+ solution. Nevertheless, SFG spectroscopy as a surface technique successfully monitored the modifications from a clean fused substrate to -COCl formation that was used to immobilize the decorated magnetic nanoparticles. The method developed in this study can provide a reference for many surface or interfacial studies important for selective attachment of adsorbed organic or inorganic materials or particles. PMID- 30300548 TI - pH and Temperature Dual-Responsive Plasmonic Switches of Gold Nanoparticle Monolayer Film for Multiple Anticounterfeiting. AB - Two-dimensional (2D) gold nanoparticle (Au NP) monolayer film possesses a lot of fascinating peculiarities, and has shown promising applications in photoelectrical devices, catalysis, spectroscopy, sensors, and anticounterfeiting. Because of the localized surface plasmon resonance (LSPR) property predetermined by the natural structure of metal nanoparticles, it is usually difficult to realize the reversible LSPR transition of 2D film. In this work, we report on the fabrication of a large-area free-standing Au NP monolayer film with dual-responsive switchable plasmonic property using a pH- or thermal responsive dendronized copolymer as a stimuli-sensitive linker. In this system, an oligoethylene-glycol-based (OEG-based) dendronized copolymer (named PG1A) with pH or temperature sensitivity was first modified onto the surface of a Au NP. Then, polyethylene glycol dibenzyl aldehyde (PEG-DA) was introduced to interact with the amino moieties from PG1A before the process of oil-water interfacial self-assembly of NPs, resulting in an elastic, robust, pH- or temperature sensitive interpenetrating network among Au NPs in monolayer films. In addition, the film could exhibit reversibly plasmonic shifts of about 77 nm and inherent color changes through varying temperature or pH. The obtained free-standing monolayer film also shows an excellent transferable property, which can be easily transferred onto substrates such as plastic molds, PDMS, copper grids, and silicon wafers. In virtue of these peculiarities of the free-standing property, special plasmonic signal, and homologous macroscopic color, the transferred film was primely applied to an anticounterfeiting security label with clear color change at the designed spots, providing a new avenue to plasmonic nanodevices with various applications. PMID- 30300549 TI - Individual Variability of Protein Expression in Human Tissues. AB - Human tissues are known to exhibit interindividual variability, but a deeper understanding of the different factors affecting protein expression is necessary to further apply this knowledge. Our goal was to explore the proteomic variability between individuals as well as between healthy and diseased samples, and to test the efficacy of machine learning classifiers. In order to investigate whether disparate proteomics data sets may be combined, we performed a retrospective analysis of proteomics data from 9 different human tissues. These data sets represent several different sample prep methods, mass spectrometry instruments, and tissue health. Using these data, we examined interindividual and intertissue variability in peptide expression, and analyzed the methods required to build accurate tissue classifiers. We also evaluated the limits of tissue classification by downsampling the peptide data to simulate situations where less data is available, such as clinical biopsies, laser capture microdissection or potentially single-cell proteomics. Our findings reveal the strong potential for utilizing proteomics data to build robust tissue classifiers, which has many prospective clinical applications for evaluating the applicability of model clinical systems. PMID- 30300550 TI - A New Strategy for Intestinal Drug Delivery via pH-Responsive and Membrane-Active Nanogels. AB - Oral administration of hydrophobic and poorly intestinal epithelium-permeable drugs is a significant challenge. Herein, we report a new strategy to overcome this problem by using novel, pH-responsive, and membrane-active nanogels as drug carriers. Prepared by simple physical cross-linking of amphiphilic pseudopeptidic polymers with pH-controlled membrane-activity, the size and hydrophobicity hydrophilicity balance of the nanogels could be well-tuned. Furthermore, the amphiphilic nanogels could release hydrophobic payloads and destabilize cell membranes at duodenum and jejunum pH 5.0-6.0, which suggests their great potential for intestinal drug delivery. PMID- 30300551 TI - Encapsulation and Release of Essential Oils in Functional Silica Nanocontainers. AB - We describe the fabrication of mesoporous silica nanocontainers (SiO2NCs) that simultaneously encapsulate different antiseptic agents. Peppermint oil (PO), thyme oil (TO), cinnamon oil (CnO), and clove oil (CO), which are known to display antibacterial properties, are loaded in the core of the silica nanocontainers that are stabilized by antiseptic surfactants. The encapsulation efficiency, surface area, and pore size are controlled by the type of oil and surfactant. The release of essential oils is further controlled by grafting oxidized hyaluronic acid on silica nanocontainers functionalized with amino groups. PMID- 30300552 TI - Phase-Transferable Force Field for Alkali Halides. AB - A longstanding goal of computational chemistry is to predict the state of materials in all phases with a single model. This is particularly relevant for materials that are difficult or dangerous to handle or compounds that have not yet been created. Progress toward this goal has been limited, as most work has concentrated on just one phase, often determined by particular applications. In the framework of the development of the Alexandria force field, we present here new polarizable force fields for alkali halides with Gaussian charge distributions for molecular dynamics simulations. We explore different descriptions of the van der Waals interaction, like the commonly applied 12-6 Lennard-Jones (LJ), and compare it to "softer" ones, such as the 8-6 LJ, Buckingham, and a modified Buckingham potential. Our results for physicochemical properties of the gas, liquid, and solid phases of alkali halides are compared to experimental data and calculations with reference polarizable and nonpolarizable force fields. The new polarizable force field that employs a modified Buckingham potential predicts the tested properties for gas, liquid, and solid phases with a very good accuracy. In contrast to reference force fields, this model reproduces the correct crystal structures for all alkali halides at low and high temperature. Seeing that experiments with molten salts may be tedious due to high temperatures and their corrosive nature, the models presented here can contribute significantly to our understanding of alkali halides in general and melts in particular. PMID- 30300553 TI - Early Emergency General Surgery Is Associated with a Higher Incidence of Clostridium difficile Infection. AB - BACKGROUND: Clostridium difficile infection (CDI) is an important surgical complication. Emergency general surgery (EGS) is a developing area of the acute care surgical practice. Few studies evaluating the incidence and risk factors of CDI in this patient population are available. PATIENTS AND METHODS: A prospectively maintained Acute and Critical Care Surgery registry spanning from 2008 to 2015 was queried for cases of operative EGS with clinical suspicion of CDI post-operatively. Diagnosis of CDI was made using toxin A/B assay in stools. Demographics, co-morbidities, surgical procedures, length of stay (LOS), intensive care unit LOS, antibiotic use, and death were obtained. The patients positive and negative for CDI were compared using chi-squared and Student's t test. Multi-variable logistic regression was used to determine risk factors for CDI. RESULTS: A total of 550 patients were identified. The total incidence of CDI was 12.7%. There was no significant difference in demographics between CDI positive and negative patients. Average time to CDI diagnosis was 10.1 +/- 8.5 days post-operatively. Patients who received three or more antibiotic classes were at higher risk of CDI developing post-operatively (83% vs. 75%, p = 0.04). The CDI positive patients underwent an EGS significantly earlier than CDI negative patients (0.9 +/- 2.3 vs. 3.2 +/- 9.2 days, p < 0.001). The most common procedures were partial colectomies (21.4%); small bowel resections/repairs (12.9%); gastric repair for perforated peptic ulcer (10%); skin and soft tissue procedure (7.1%), and laparotomies (5.7%). There was no difference in outcomes between the groups. On linear regression, an EGS performed later after admission was an independent risk factor for lower CDI (OR 0.87; CI 95% [0.79-0.96], p < 0.01). CONCLUSION: Patients undergoing an early EGS have a high incidence of CDI. The number of antibiotic classes administered post-operatively affects CDI status. Bowel resections appear to be at increased risk for CDI. Clinicians should have a high index of suspicion and low threshold for testing C. difficile in high-risk EGS patients. PMID- 30300555 TI - Linking Opioid-Overdose Data to Human Services and Criminal Justice Data: Opportunities for Intervention. AB - OBJECTIVES:: In Allegheny County, Pennsylvania, the incidence of opioid-related overdose deaths increased from 17.4 per 100 000 population in 2008 to 23.9 per 100 000 population in 2014. Our objectives were to describe local demographic characteristics of this epidemic, identify public human services targets for intervention, determine temporal relationships between use of public human services and overdose mortality, and provide recommendations about potentially beneficial interventions. METHODS:: We used autopsy data from the Allegheny County Medical Examiner to link people who died of overdoses from 2008 through 2014 to their premortem incarcerations and use of mental health services and substance use disorder services. We calculated the frequency of use of public human services by decedents and the interval between the last use of these services and overdose death. RESULTS:: Of the 1399 decedents, 957 (68.4%) had a public human service encounter before overdose death. Of these 957 decedents, 531 (55.5%) had ever been incarcerated, 616 (64.4%) had ever used a mental health service, and 702 (73.4%) had ever used a substance use disorder service. Of 211 decedents incarcerated in the year before their overdose death, 54 (25.6%) overdosed within 30 days of their last release from jail. Of 510 decedents using mental health services in the year before death, 231 (45.3%) overdosed within 30 days of their last use of the services. Of 350 decedents using substance use disorder services in the year before their overdose death, 134 (38.3%) overdosed within 30 days of their last use of the services. CONCLUSIONS:: Merging data on overdose mortality with data on use of public human services can be a useful strategy to identify trends in, and factors contributing to, the opioid epidemic; to target interventions; and to stimulate collaboration to address the epidemic.

PMID- 30300557 TI - In Vitro Flow Rate Dependency of Delivered Dose and Fine Particle Dose of Salmeterol/Fluticasone Propionate Easyhaler and Seretide Diskus with Patient Flow Rates Collected in a Randomized Controlled Trial. AB - BACKGROUND: The Easyhaler(r) device-metered dry powder inhaler containing Salmeterol and Fluticasone propionate (S/F) has been developed for the treatment of patients with asthma and chronic obstructive pulmonary disease (COPD). We report two studies which evaluated the in vitro flow rate dependence of delivered dose (DD) and fine particle dose (FPD) of S/F Easyhaler versus Seretide Diskus(r). METHODS: A randomized controlled trial (RCT) assessed inspiratory flow parameters of S/F Easyhaler and Seretide Diskus in subgroups of patients with asthma (children, adolescents and adults, and elderly) and in COPD patients. The 10th, 50th, and 90th percentile airflow rates were determined and utilized in vitro, to evaluate flow rate dependence of DD and FPD. Flow rate dependence was evaluated relative to the result obtained at the 50th percentile and any values deviating from 100% indicated flow rate dependence. The volumetric flow rate dependence (Q) index derived from FPD at 10th and 90th percentile airflows was also evaluated. RESULTS: Overall, 227 patients were enrolled and randomized; 216 completed the RCT. In total, 55.5% of patients were female, and the mean age was 46.3 years. Clinically relevant airflow rates (46, 68, and 85 L/min for S/F Easyhaler and 44, 71, and 96 L/min for Seretide Diskus) were carried forward into the in vitro study, which demonstrated similar flow rate dependence of DD and FPD for S/F Easyhaler compared with Seretide Diskus; all values were within +/-15% limits across the 10th, 50th, and 90th percentile airflow rates. Q index results suggested that both S/F Easyhaler and Seretide Diskus are medium airflow dependent products. CONCLUSIONS: Similar in vitro flow rate dependence of DD and FPD was demonstrated for S/F Easyhaler compared with Seretide Diskus, across a range of clinically relevant airflow rates, collected from patients with asthma and COPD.

AB - The purpose of this study is to present themes from a novel group therapy intervention for veterans with aggression. The groups were designed based on a psychodynamic rather than cognitive?behavioral theoretical framework, in which there are two overlapping short and long-term groups. Content analysis revealed six themes including, control your anger, helplessness, improvement, disagreements, where are the boundaries, and co-leadership, parallel process. This unique and innovative approach for the treatment of veterans with a history of aggressive behavior helped improved their understanding of aggression and decreased these behaviors. This group model may also have potential to be expanded to other patient populations with similar behaviors. PMID- 30300561 TI - Fecal Microbiota Transplantation for the Management of Clostridium difficile Infection. AB - The clinical burden of Clostridium difficile infection (CDI) continues to grow. Despite the multitude of treatment options that have been developed and tested to combat the morbidity and death associated with CDI, recurrence remains common. As such, treatment modalities such as fecal microbiota transplantation (FMT) have become studied increasingly; FMT serves to transplant stool from carefully selected healthy subjects into C. difficile positive patients through a variety of delivery routes. In doing so, FMT is hypothesized to correct dysbiosis of the recipient gut microbiome addressing the root cause of the pathogenesis of C. difficile infection. A growing body of evidence shows FMT to be efficacious in this setting, and the study of FMT accordingly continues to evolve to identify novel indications for its utilization. PMID- 30300560 TI - Racial/Ethnic Disparities in Influenza Vaccination Coverage Among US Adolescents, 2010-2016. AB - OBJECTIVE:: Although research suggests racial/ethnic disparities in influenza vaccination and mortality rates, few studies have examined racial/ethnic trends among US adolescents. We used national cross-sectional data to determine (1) trends in influenza vaccination rates among non-Hispanic white (hereinafter, white), non-Hispanic black (hereinafter, black), and Hispanic adolescents over time and (2) whether influenza vaccination rates among adolescents varied by race/ethnicity. METHODS:: We analyzed provider-reported vaccination histories for 2010-2016 from the National Immunization Survey-Teen. We used binary logistic regression models to determine trends in influenza vaccination rates by race/ethnicity for 117 273 adolescents, adjusted for sex, age, health insurance, physician visit in the previous 12 months, vaccination facility type, poverty status, maternal education level, children in the household, maternal marital status, maternal age, and census region of residence. We calculated adjusted probabilities for influenza vaccination for each racial/ethnic group, adjusted for the same demographic characteristics. RESULTS:: Compared with white adolescents, Hispanic adolescents had higher odds (adjusted odds ratio [aOR] = 1.11; 95% confidence interval [CI], 1.06-1.16) and black adolescents had lower odds (aOR = 0.95; 95% CI, 0.90-1.00) of vaccination. Compared with white adolescents, Hispanic adolescents had significantly higher adjusted probabilities of vaccination for 2011-2013 (2011: 0.22, P < .001; 2012: 0.23, P < .001; 2013: 0.26, P < .001). Compared with white adolescents, black adolescents had significantly lower probabilities of vaccination for 2016 (2016: 0.21, P < .001). CONCLUSIONS:: Targeted interventions are needed to improve adolescent influenza vaccination rates and reduce racial/ethnic disparities in adolescent vaccination coverage. PMID- 30300563 TI - Antiseptic Irrigation as an Effective Interventional Strategy for Reducing the Risk of Surgical Site Infections. AB - A surgical site infection (SSI) can occur at several anatomic sites related to a surgical procedure: Superficial or deep incisional or organ/space. The SSIs are the leading cause of health-care-associated infection (HAI) in industrialized Western nations. Patients in whom an SSI develops require longer hospitalization, incur significantly greater treatment costs and reduction in quality of life, and after selective surgical procedures experience higher mortality rates. Effective infection prevention and control requires the concept of the SSI care bundle, which is composed of a defined number of evidence-based interventional strategies, because of the many risk factors that can contribute to the development of an SSI. Intra-operative irrigation has been a mainstay of surgical practice for well over 100 years, but lacks standardization and compelling evidence-based data to validate its efficacy. In an era of antibiotic stewardship, with a widespread prevalence of bacterial resistance to multiple antibiotic agents, there has emerged an interest in using intra-operative antiseptic irrigation to reduce microbial contamination in the surgical site before closure and possibly reduce the need for antibiotic agents. This approach has gained added appeal in an era of biomedical device implantation, especially with the recognition that most, if not all, device-related infections are associated with biofilm formation. This review focuses on the limited, evidence based rationale for the use of antiseptic agents as an effective risk reduction strategy for prevention of SSIs. PMID- 30300564 TI - Bioinformatics Analysis and Competitive Regulation by Transcription Factors of SIRT5 at the Core Promoter Region Using Bovine Adipocytes. AB - Sirtuin 5 (SIRT5) belongs to the mitochondrial sirtuin family, which constitutes a highly conserved family of nicotinamide adenine dinucleotide NAD+-dependent deacetylases and ADP-ribosyltransferases that play an important regulatory role in stress resistance and metabolic homeostasis. SIRT5, a member of the mitochondrial sirtuins, has been confirmed to exhibit deacetylase, desuccinylase, and demalonylase enzymatic activities. First, we showed that SIRT5 was expressed at the highest level in the bovine testis, followed by longissimus thoracis and subcutaneous adipose tissue, using real-time quantitative PCR and mRNA levels of SIRT5 during adipocyte differentiation, which increased before the first day and then decreased rapidly. To explore the molecular regulation of bovine SIRT5 expression, we cloned a 2-kb fragment of the 5'-regulatory region and the functional proximal minimal promoter of bovine SIRT5. Electrophoretic mobility shift assays and luciferase reporter assays identified Kruppel-like factor 2 (KLF2), CCAAT enhancer binding protein beta (CEBPbeta), peroxisome proliferator activated receptor alpha (PPARalpha), myogenic differentiation 1 (MYOD), and nuclear respiratory factor 1 (NRF1) binding sites as transcriptional activators or repressors in the core promoter region of SIRT5. In brief, our study focused on the mechanism underlying the transcriptional regulation of SIRT5 expression in bovine adipocytes. PMID- 30300565 TI - Juxtafacial Lipoma within the Mastoid Bone.

PMID- 30300567 TI - The Effect of Pectins on Water Crystallization Pattern and Integrity of Cells During Freezing. AB - The ability of various pectin polysaccharides to modify the morphological structure of ice during the phase transitions from water to ice was studied. Pectins were isolated from Sosnowsky's hogweed Heracleum sosnowskyi Manden (heracleuman-N6HS), tansy Tanacetum vulgare L. (tanacetan-N7TVF), and Rauwolfia serpentina Benth callus (rauwolfian-N8RS). Pectins were isolated by multistep extraction. The effect of pectins was assessed using osmometry, thermographic analysis, and cryomicroscopy. A concentrate of leukocytes was used as the sample for the subsequent freezing step. The condition of the leukocyte membrane, and lysosomal and phagocytic activity after a freezing-warming process were assessed. Osmotic concentrations of the pectin polysaccharide solutions were found to be very low. The 0.4 wt % N7TVF solution had the highest osmotic concentration as well as freezing point; however, the duration of its crystallization plateau was lower than that of the 0.4 wt % and 0.2 wt % N6HS solutions. All studied polysaccharide solutions demonstrated a high linear rate of ice crystal growth. There were statistically significant differences between the melting rates for the 0.2% solutions of the pectins, N6HS and N7TVF, N6HS and N8RS, as well as between concentrations for the pectin N7TVF and between concentrations for the pectin N8RS. The data on the integrity of cells that are frozen in a medium containing polysaccharides may indicate a cryoprotective effect of the N7TVF and N8RS pectins, that is, tanacetan from tansy and rauwolfian from rauwolfia. The most effective modifier among the substances, which were studied by us, was the N7TVF pectin polysaccharide (tanacetan from tansy).

AB - In 2015, the University of Washington School of Public Health, Department of Epidemiology established the Student Epidemic Action Leaders (SEAL) team to provide public health students with experience in field epidemiology in state and local public health communicable disease divisions. The University of Washington Department of Epidemiology developed the SEAL team in collaboration with the Washington State Department of Health to offer public health graduate students opportunities to contribute to the real-time needs of public health agencies during a communicable disease event and/or preparedness event. The SEAL team combines classroom and field-based training in public health practice and applied epidemiology. During the first 2 years of the SEAL team (2016-2018), 34 SEALs were placed at 4 agencies contributing more than 1300 hours of assistance on 24 public health projects. PMID- 30300569 TI - Microbe Isolation from Blood, Central Venous Catheters, and Fluid Collections after Liver Resections. AB - BACKGROUND: Our goal was to evaluate the microbe species responsible for bacteremia or infections related to central venous catheter (CVC) or fluid collections after liver resection. PATIENTS AND METHODS: Data from 112 patients (68 males, 44 females) who underwent liver resection over a period of 63 months were reviewed. Patient and tumor characteristics, intra-operative and post operative data, and the results from cultures of peripheral blood, CVC tips and drained intra-abdominal or intra-throracic fluid collections were collected. RESULTS: There were positive blood cultures in 20 patients (17.9%). Coagulase negative staphylococci (CoNS) and bacteria of enteric flora were the micro organisms found most frequently and half of the cases had multiple isolated microbe species. The construction of a bilioenteric anastomosis was an independent risk factor for microbe isolation in peripheral blood (odds ratio [OR]: 11, p = 0.01). Furthermore, there were positive cultures of the CVC tip in 14 patients (12.5%), with CoNS being the micro-organism found most frequently and most cases had only one isolated microbe species. No specific risk factor for catheter-related infections was detected. In addition, there were positive cultures of drained fluid collections in 19 patients (17%), with bacteria of enteric flora being the micro-organisms found most frequently and the majority of cases had multiple isolated microbe species. The construction of a bilioenteric anastomosis (OR: 23.5, p = 0.002) and the laparoscopic approach (OR: 4.7, p = 0.0496) were independent risk factors for microbe isolation in drained fluid collections. Finally, the presence of positive blood cultures was associated with the presence of positive culture of CVC tips (p = 0.018) and drained fluid collections (p = 0.001). CONCLUSIONS: Post-operative bacteremia, colonization of CVCs, and contamination of fluid collections occur frequently after liver resections and various microbe species may be involved. Patients who undergo hepatectomy and a synchronous construction of a bilioenteric anastomosis are at increased risk of bacteremia development and contamination of fluid collections. PMID- 30300570 TI - Losing our soul: American values. PMID- 30300571 TI - Development of an Embryonic Zebrafish Oligodendrocyte-Neuron Mixed Coculture System. AB - During vertebrate neural development, oligodendrocytes insulate nerve axons with myelin sheaths. Zebrafish (Danio rerio) has emerged as a useful model organism for studying oligodendrocyte development. However, the absence of an in vitro culture system necessitates in vivo manipulations and analyses, which, in some instances, limits the questions that can be addressed. To fill this gap we developed a mixed coculture system for embryonic zebrafish neurons and oligodendrocyte-lineage cells. Cultures harvested from embryos >=30 hours postfertilization (hpf) yielded oligodendrocyte progenitor cells (OPCs) positive for olig2 and sox10 transgenic reporters. Cultured OPCs exhibited dynamic, exploratory membrane processes, and cell morphologies resembled those established in vivo. Cells harvested from advanced stage embryos possessed more arborized processes than those from early stage embryos. Advanced stage (>60 hpf) embryo culture produced differentiated, mbp+ oligodendrocytes. Genetically tractable neuron subtypes extended neurites when harvested from embryos >=19 hpf. Coculture produced juxtaposed oligodendrocytes and neurons, demonstrating the practical usefulness of this technique for future studies examining axon-oligodendrocyte interactions under defined conditions. We expect that zebrafish oligodendrocyte culture will complement existing in vivo strengths and may facilitate future studies elucidating the mechanisms of oligodendrocyte specification, proliferation, differentiation, motility, and axon-oligodendrocyte interactions that shape adult myelination patterns. PMID- 30300572 TI - Motor Neuron Abnormalities Correlate with Impaired Movement in Zebrafish that Express Mutant Superoxide Dismutase 1. AB - Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive loss of motor neurons. ALS can be modeled in zebrafish (Danio rerio) through the expression of human ALS-causing genes, such as superoxide dismutase 1 (SOD1). Overexpression of mutated human SOD1 protein causes aberrant branching and shortening of spinal motor axons. Despite this, the functional relevance of this axon morphology remains elusive. Our aim was to determine whether this motor axonopathy is correlated with impaired movement in mutant (MT) SOD1-expressing zebrafish. Transgenic zebrafish embryos that express blue fluorescent protein (mTagBFP) in motor neurons were injected with either wild-type (WT) or MT (A4V) human SOD1 messenger ribonucleic acid (mRNA). At 48 hours post-fertilization, larvae movement (distance traveled during behavioral testing) was examined, followed by quantification of motor axon length. Larvae injected with MT SOD1 mRNA had significantly shorter and more aberrantly branched motor axons (p < 0.002) and traveled a significantly shorter distance during behavioral testing (p < 0.001) when compared with WT SOD1 and noninjected larvae. Furthermore, there was a positive correlation between distance traveled and motor axon length (R2 = 0.357, p < 0.001). These data represent the first correlative investigation of motor axonopathies and impaired movement in SOD1-expressing zebrafish, confirming functional relevance and validating movement as a disease phenotype for the testing of disease treatments for ALS. PMID- 30300573 TI - Contribution of Vaccination to the Reduction of Infectious Mortality in Ukraine in the Second Half of the 20th and Early 21st Century: A Comparative Population Based Study of the Dynamics and Structure of Infectious Mortality and Incidence. AB - Our work presents an epidemiological analysis of the dynamics and structure of the annual indicators such as Cumulative Incidence, Mortality Rate (MR), and Case Fatality Rate for infections preventable by vaccines (vaccine-preventable infections-VPIs) in Ukraine between 1944 and 2015 compared to the same indicators for infections not preventable by vaccines (nonvaccine-preventable infections-non VPIs). In 1965, the proportion of all infectious diseases in the context of mortality (7.47%), and especially of VPI (3.77%), including those registered among children aged 0-14 years (2.12%), testifies to the low profile of infectious diseases by the time of routine vaccination introduction. The analyses of these particular data are important with respect to the role of vaccination programs in reducing not only the total infectious mortality but also mortality related to VPIs in the twentieth century. Interestingly, in Ukraine between 1965 and 2015, similar rates of mortality reduction were observed in both the total population (1.6-2.6 times) and in children under 14 (15.2-20.4 times) for both VPIs and non-VPIs. During the 1944-2015 period in Ukraine, the reduction of MR of VPI (tuberculosis, diphtheria, tetanus, pertussis, poliomyelitis, measles, and hepatitis B) varied greatly, ranging from 40.5 times (tetanus) to 1,061.1 times (measles), but in general, the reduction incidence rate of VPI was significantly lower ranging from 42.4 times (measles) to 471.1 times (diphtheria). The ratio of incidence and mortality reduction in percent shows the contribution of vaccination to the mortality reduction for various infections during 1944-2015. This ratio ranged from 0% (tuberculosis) to 84.9% (tetanus), provided that the reduction of the VPI incidence 100% depends on vaccine effects. Thus, we can assume that the observed reduction in mortality for some VPIs was, in part, caused by factors not associated with vaccines. PMID- 30300574 TI - Identification of a Novel Zebrafish Mutant Line that Develops Testicular Germ Cell Tumors. AB - Testicular tumors are the most common solid malignant tumors in men 20-35 years of age. Although most of testicular tumors are curable, current treatments still fail in 15%-20% of patients. However, insufficient understanding of the molecular basis and lack of animal models limit development of more effective treatments. This study reports the identification of a novel zebrafish mutant line, ns1402, which develops testicular germ cell tumors (TGCTs). While both male and female ns1402 mutants were fertile at young age, male ns1402 mutants became infertile as early as 9 months of age. This infertility was associated with progressive loss of mature sperm. Failure of spermatogenesis was, at least in part, explained by progressive loss of mature Leydig cells, a source of testosterone that is essential for spermatogenesis. Interestingly, TGCTs in ns1402 mutants contained a large number of Sertoli cells and gene expression profiles of Sertoli cells were altered before loss of mature Leydig cells. This suggests that changes in Sertoli cell properties happened first, followed by loss of mature Leydig cells and failure of spermatogenesis. Taken together, this study emphasizes the importance of cell-cell interactions and cell signaling in the testis for spermatogenesis and tissue homeostasis.

PMID- 30300578 TI - Integrated Analysis of Genetic Ancestry and Genomic Alterations across Cancers. AB - Disparities in cancer care have been a long-standing challenge. We estimated the genetic ancestry of The Cancer Genome Atlas patients, and performed a pan-cancer analysis on the influence of genetic ancestry on genomic alterations. Compared with European Americans, African Americans (AA) with breast, head and neck, and endometrial cancers exhibit a higher level of chromosomal instability, while a lower level of chromosomal instability was observed in AAs with kidney cancers. The frequencies of TP53 mutations and amplification of CCNE1 were increased in AAs in the cancer types showing higher levels of chromosomal instability. We observed lower frequencies of genomic alterations affecting genes in the PI3K pathway in AA patients across cancers. Our result provides insight into genomic contribution to cancer disparities. PMID- 30300580 TI - MYC Interacts with the G9a Histone Methyltransferase to Drive Transcriptional Repression and Tumorigenesis. AB - MYC is an oncogenic driver that regulates transcriptional activation and repression. Surprisingly, mechanisms by which MYC promotes malignant transformation remain unclear. We demonstrate that MYC interacts with the G9a H3K9-methyltransferase complex to control transcriptional repression. Inhibiting G9a hinders MYC chromatin binding at MYC-repressed genes and de-represses gene expression. By identifying the MYC box II region as essential for MYC-G9a interaction, a long-standing missing link between MYC transformation and gene repression is unveiled. Across breast cancer cell lines, the anti-proliferative response to G9a pharmacological inhibition correlates with MYC sensitivity and gene signatures. Consistently, genetically depleting G9a in vivo suppresses MYC dependent tumor growth. These findings unveil G9a as an epigenetic regulator of MYC transcriptional repression and a therapeutic vulnerability in MYC-driven cancers. PMID- 30300579 TI - Complement C5a Fosters Squamous Carcinogenesis and Limits T Cell Response to Chemotherapy. AB - Complement is a critical component of humoral immunity implicated in cancer development; however, its biological contributions to tumorigenesis remain poorly understood. Using the K14-HPV16 transgenic mouse model of squamous carcinogenesis, we report that urokinase (uPA)+ macrophages regulate C3 independent release of C5a during premalignant progression, which in turn regulates protumorigenic properties of C5aR1+ mast cells and macrophages, including suppression of CD8+ T cell cytotoxicity. Therapeutic inhibition of C5aR1 via the peptide antagonist PMX-53 improved efficacy of paclitaxel chemotherapy associated with increased presence and cytotoxic properties of CXCR3+ effector memory CD8+ T cells in carcinomas, dependent on both macrophage transcriptional programming and IFNgamma. Together, these data identify C5aR1 dependent signaling as an important immunomodulatory program in neoplastic tissue tractable for combinatorial cancer immunotherapy. PMID- 30300582 TI - Pharmacological Induction of RAS-GTP Confers RAF Inhibitor Sensitivity in KRAS Mutant Tumors. AB - Targeting KRAS mutant tumors through inhibition of individual downstream pathways has had limited clinical success. Here we report that RAF inhibitors exhibit little efficacy in KRAS mutant tumors. In combination drug screens, MEK and PI3K inhibitors synergized with pan-RAF inhibitors through an RAS-GTP-dependent mechanism. Broad cell line profiling with RAF/MEK inhibitor combinations revealed synergistic efficacy in KRAS mutant and wild-type tumors, with KRASG13D mutants exhibiting greater synergy versus KRASG12 mutant tumors. Mechanistic studies demonstrate that MEK inhibition induced RAS-GTP levels, RAF dimerization and RAF kinase activity resulting in MEK phosphorylation in synergistic tumor lines regardless of KRAS status. Taken together, our studies uncover a strategy to rewire KRAS mutant tumors to confer sensitivity to RAF kinase inhibition. PMID- 30300581 TI - Enhanced Anti-lymphoma Activity of CAR19-iNKT Cells Underpinned by Dual CD19 and CD1d Targeting. AB - Chimeric antigen receptor anti-CD19 (CAR19)-T cell immunotherapy-induced clinical remissions in CD19+ B cell lymphomas are often short lived. We tested whether CAR19-engineering of the CD1d-restricted invariant natural killer T (iNKT) cells would result in enhanced anti-lymphoma activity. CAR19-iNKT cells co-operatively activated by CD1d- and CAR19-CD19-dependent interactions are more effective than CAR19-T cells against CD1d-expressing lymphomas in vitro and in vivo. The swifter in vivo anti-lymphoma activity of CAR19-iNKT cells and their enhanced ability to eradicate brain lymphomas underpinned an improved tumor-free and overall survival. CD1D transcriptional de-repression by all-trans retinoic acid results in further enhanced cytotoxicity of CAR19-iNKT cells against CD19+ chronic lymphocytic leukemia cells. Thus, iNKT cells are a highly efficient platform for CAR-based immunotherapy of lymphomas and possibly other CD1d-expressing cancers.

AB - Oncogenic transcription factors such as the leukemic fusion protein RUNX1/ETO, which drives t(8;21) acute myeloid leukemia (AML), constitute cancer-specific but highly challenging therapeutic targets. We used epigenomic profiling data for an RNAi screen to interrogate the transcriptional network maintaining t(8;21) AML. This strategy identified Cyclin D2 (CCND2) as a crucial transmitter of RUNX1/ETO driven leukemic propagation. RUNX1/ETO cooperates with AP-1 to drive CCND2 expression. Knockdown or pharmacological inhibition of CCND2 by an approved drug significantly impairs leukemic expansion of patient-derived AML cells and engraftment in immunodeficient murine hosts. Our data demonstrate that RUNX1/ETO maintains leukemia by promoting cell cycle progression and identifies G1 CCND-CDK complexes as promising therapeutic targets for treatment of RUNX1/ETO-driven AML.

Mechanical forces play critical roles in AJs' composition and dynamics. Recent findings highlight that beyond a well-established role in reinforcing cell-cell adhesion, AJ mechanosensitivity promotes junctional remodeling and polarization, thereby regulating critical processes such as cell intercalation, division, and collective migration. Here, we provide an integrated view of mechanosensing mechanisms that regulate cell-cell contact composition, geometry, and integrity under tension and highlight pivotal roles for mechanosensitive AJ remodeling in preserving epithelial integrity and sustaining tissue dynamics.

AB - Developmental neuronal remodeling is an evolutionarily conserved mechanism required for precise wiring of nervous systems. Despite its fundamental role in neurodevelopment and proposed contribution to various neuropsychiatric disorders, the underlying mechanisms are largely unknown. Here, we uncover the fine temporal transcriptional landscape of Drosophila mushroom body gamma neurons undergoing stereotypical remodeling. Our data reveal rapid and dramatic changes in the transcriptional landscape during development. Focusing on DNA binding proteins, we identify eleven that are required for remodeling. Furthermore, we sequence developing gamma neurons perturbed for three key transcription factors required for pruning. We describe a hierarchical network featuring positive and negative feedback loops. Superimposing the perturbation-seq on the developmental expression atlas highlights a framework of transcriptional modules that together drive remodeling. Overall, this study provides a broad and detailed molecular insight into the complex regulatory dynamics of developmental remodeling and thus offers a pipeline to dissect developmental processes via RNA profiling. PMID- 30300593 TI - Chromokinesins. AB - During the cell cycle it is critical that the duplicated DNA faithfully segregates to give rise to two genetically identical daughter cells. An even distribution of the genome during mitosis is mediated by mitotic spindle microtubules, assisted by, among others, motor proteins of the kinesin superfamily. Chromokinesins are members of the kinesin superfamily that harbour a specific DNA-binding domain. The best characterized chromokinesins belong to the kinesin-4/Kif4 and kinesin-10/Kif22 families, respectively. Functional analysis of chromokinesins in several model systems revealed their involvement in chromosome arm orientation and oscillations. This is consistent with their originally proposed role in the generation of polar ejection forces that assist chromosome congression to the spindle equator. Kinesin-12/Kif15 members comprise a third family of chromokinesins, but their role remains less understood. Noteworthy, all chromokinesins exhibit chromosome-independent localization on spindle microtubules, and recent works have significantly extended the portfolio of mitotic processes in which chromokinesins play a role, from error correction and DNA compaction, to the regulation of spindle microtubule dynamics. PMID- 30300594 TI - Avoiding death by feigning death. AB - Thanatosis is a common phenomenon in which prey appear to feign death when attacked by predators. It was once widely believed that thanatosis exploited predators' tendencies to avoid dead prey. However, this hypothesis has never been tested, and its feasibility has been questioned to the point that it has been largely abandoned [1,2]. Here, I show that naive birds quickly learned that dead Indian stick insects Carausius morosus were unpalatable, and subsequently rejected live insects that displayed thanatosis, but not those that failed to show thanatosis. Thanatosis had no effect on the behavior of birds that had never experienced dead insects, or those that had experienced dead insects whose resemblance to thanatosic insects had been destroyed. Therefore, thanatosis clearly caused predators to avoid prey that they mistakenly perceived to be dead. PMID- 30300595 TI - Marine plastics threaten giant Atlantic Marine Protected Areas. AB - There has been a recent shift in global perception of plastics in the environment, resulting in a call for greater action. Science and the popular media have highlighted plastic as an increasing stressor [1,2]. Efforts have been made to confer protected status to some remote locations, forming some of the world's largest Marine Protected Areas, including several UK overseas territories. We assessed plastic at these remote Atlantic Marine Protected Areas, surveying the shore, sea surface, water column and seabed, and found drastic changes from 2013-2018. Working from the RRS James Clark Ross at Ascension, St. Helena, Tristan da Cunha, Gough and the Falkland Islands (Figure 1A), we showed that marine debris on beaches has increased more than 10 fold in the past decade. Sea surface plastics have also increased, with in-water plastics occurring at densities of 0.1 items m-3; plastics on seabeds were observed at <= 0.01 items m 2. For the first time, beach densities of plastics at remote South Atlantic sites approached those at industrialised North Atlantic sites. This increase even occurs hundreds of meters down on seamounts. We also investigated plastic incidence in 2,243 animals (comprising 26 species) across remote South Atlantic oceanic food webs, ranging from plankton to seabirds. We found that plastics had been ingested by primary consumers (zooplankton) to top predators (seabirds) at high rates. These findings suggest that MPA status will not mitigate the threat of plastic proliferation to this rich, unique and threatened biodiversity. PMID- 30300596 TI - Protection against the lethal side effects of social immunity in ants. AB - Many animals use antimicrobials to prevent or cure disease [1,2]. For example, some animals will ingest plants with medicinal properties, both prophylactically to prevent infection and therapeutically to self-medicate when sick. Antimicrobial substances are also used as topical disinfectants, to prevent infection, protect offspring and to sanitise their surroundings [1,2]. Social insects (ants, bees, wasps and termites) build nests in environments with a high abundance and diversity of pathogenic microorganisms - such as soil and rotting wood - and colonies are often densely crowded, creating conditions that favour disease outbreaks. Consequently, social insects have evolved collective disease defences to protect their colonies from epidemics. These traits can be seen as functionally analogous to the immune system of individual organisms [3,4]. This 'social immunity' utilises antimicrobials to prevent and eradicate infections, and to keep the brood and nest clean. However, these antimicrobial compounds can be harmful to the insects themselves, and it is unknown how colonies prevent collateral damage when using them. Here, we demonstrate that antimicrobial acids, produced by workers to disinfect the colony, are harmful to the delicate pupal brood stage, but that the pupae are protected from the acids by the presence of a silk cocoon. PMID- 30300597 TI - Roads threaten Asiatic cheetahs in Iran. AB - Wildlife-vehicle collisions are an important cause of mortality for many animal species. They also prove extremely detrimental to the critically endangered Asiatic cheetah (Acinonyx jubatus venaticus) [1,2]. One to two Asiatic cheetahs are killed by vehicles on Iran's roads annually [3,4]. As such, the Asiatic cheetah could be the next charismatic felid subspecies to go extinct in the near future [5]. We identified one statistically-significant cluster of cheetah vehicle collisions on the Shahroud-Sabzevar Highway (SSH), in Semnan Province. Because of the extremely small population of cheetahs and the corresponding difficulty of finding statistically-significant clusters, we propose that every single cheetah-vehicle collision should be considered important. We further recommend that wildlife underpasses and associated fencing be constructed in areas of previous cheetah-vehicle collisions.

PMID- 30300606 TI - Lingering Effects of Herbivory and Plant Defenses on Pollinators. AB - In order to survive and reproduce, flowering plants must balance the conflicting selective pressures of herbivore avoidance and pollinator attraction. Links between herbivory and reproduction are often attributed to indirect effects of leaf damage on pollination via reductions in floral allocation, or increases in chemical defenses on herbivore-damaged plants. However, the impacts of herbivory on pollinators have the potential to extend beyond initial floral visits when plant defenses impact pollinator health, foraging behavior, and reproductive success. Here, we examine important but underexplored ways in which herbivory may alter floral phenotype and thus impact pollinators. First, we outline genetic and biochemical mechanisms predicted to underlie floral changes following herbivory, as they impact the floral resources (nectar and pollen) sought by pollinators. Next, we discuss how the consumption of secondary compounds might impact pollinator fitness, including carryover effects on subsequent foraging, mating success, and transgenerational effects on offspring. We consider how pollinator health, life history, and coevolutionary history might result in context dependent impacts of plant defensive chemistry on pollinator fitness. Finally, we call for studies that measure the impact of herbivore-induced plant defenses on the full spectrum of flower visitors, and contrast case studies on conventional pollinators (for example, generalized bees) versus insects whose larvae are herbivores on the same plants that adults pollinate (such as several butterflies and moths). By linking these consequences of herbivory to fitness effects on both herbivores and pollinators, we will better understand how coevolution between plants, herbivores, and pollinators shapes both defensive and reproductive plant traits. PMID- 30300607 TI - The role of the laboratory in the expanding field of neuroimmunology: Autoantibodies to neural targets. AB - Accelerated identification of autoantibodies associated with previously idiopathic neurological disease has provided insights into disease mechanisms, enhanced understanding of neurological function, and opportunities for improved therapeutic interventions. The role of the laboratory in the expanding field of neuroimmunology is critical as specific autoantibody identification provides guidance to clinicians in diagnosis, prognosis, tumor search strategies, and therapeutic interventions. The number of specific autoantibodies identified continues to increase and newer testing strategies increase efficiencies in the laboratory and availability to clinicians. The need for broadly targeted efficient testing is underscored by the variability in clinical presentation and tumor associations attributable to a specific autoantibody, and conversely the various autoantibody specificities that can be the cause of a given clinical presentation. While many of the antineural antibodies were first recognized in the setting of neoplastic disease, idiopathic autoimmune neurological disease in the absence of underlying tumor is increasingly recognized. Appropriation of therapeutic modalities used to treat autoimmune disease to treat these autoantibody mediated neurological diseases has improved patient outcomes. Interaction between clinicians and laboratorians is critical to our understanding of these diseases and optimization of the clinical benefits of our increasing knowledge in neuroimmunology. PMID- 30300608 TI - Detection and identification of potential transglutaminase 2 substrates in the mouse renal glomeruli. AB - The glomerulus primarily comprises mesangial cells, glomerular microvascular endothelial cells, and podocytes. IgA nephropathy is the most common primary glomerulonephritis worldwide and has a risk of progression to end-stage renal disease. IgA nephropathy is characterized by predominant IgA deposition in the glomerular mesangial area, where TG2 is significantly enhanced. Therefore, identification of glomerular TG2 substrates is the first step in elucidating the role of TG2 as a crosslinking enzyme during disease progression. To clarify potential glomerular TG2 substrates, and to establish a procedure for substrate identification, we attempted to identify those molecules using normal mouse glomeruli. Extracts from mouse glomerular and non-glomerular fractions were treated with our established biotin-labeled substrate peptide, which specifically crosslinks to the lysine-donor substrates depending on TG2 activity. Peptide incorporated proteins were then purified using avidin resin and identified via mass spectrometry. In parallel, we performed the identification using corresponding samples from TG2 knockout mice. Consequently, potential TG2 substrates were separately identified in glomerular and non-glomerular fractions. They were mainly identified as novel TG2 substrates and partly include the well known substrates. These results potentially provide novel insights into the mechanism underlying IgA nephropathy and may help elucidate the physiological functions of TG2.

PMID- 30300610 TI - Neuroendocrine stress response is moderated by sex and sex hormone receptor polymorphisms. AB - Sex hormones are significant regulators of stress reactivity, however, little is known about how genetic variation in hormone receptors contributes to this process. Here we report interactions between biological sex and repeat polymorphisms in genes encoding sex hormone receptors, and their effects on salivary cortisol reactivity in a sample of 100 participants (47 men & 53 women; 24.7 +/- 3.23 years). Three genes were investigated: estrogen receptors alpha (ESR1) and beta (ESR2), and the androgen receptor (AR). Participants were classified as carrying 'Short' or 'Long' alleles based on median splits of the repeat distribution for each gene. Measures of physiological reactivity were collected before and after exposure to a canonical laboratory stressor and converted to traditional summary measures for analyses. Overall, men exhibited greater cortisol (p = 0.001) and mean arterial pressure reactivity (p = 0.002), while women displayed elevated heart rate throughout the session (p = 0.02). The effect of polymorphisms on salivary cortisol was sex sensitive. ESR1 was associated with differential reactivity in men (p = 0.04), but not women (p = 0.24). ESR2 genotype interacted with sex such that each additional 'Long' allele was associated with a 6.4% decrease in salivary cortisol in men, but a 9.5% increase in the levels of women (p = 0.02 for interaction). For the X-linked AR, the 'Long' allele was associated with decreased cortisol levels in men (p = 0.047), but in women had no effect (p = 0.75). Together, these results provide evidence for the saliency of genetic variation in sex hormone receptors on stress reactivity in humans and highlight their important role as mediators of hormonal activity.

AB - Matrix metalloproteinases (Mmps) are pivotal extracellular proteinases participating in tissue remodeling. Three Mmps genes have been identified from the silkworm, Bombyx mori, and their expression levels and enzyme activity are consistent with progressive fat body cell dissociation during the early pupal stages. Using both loss-of-function and gain-of-function experiments, we have demonstrated that Mmps are functionally required for fat body cell dissociation and ovary development in female pupae. Moderate inhibition of Mmps activity via inhibitor treatments delayed fat body cell dissociation and ovary development, while severe inhibition blocked these developmental processes and eventually led to pupal lethality. Individual RNAi knockdown of each Mmp delayed fat body cell dissociation, with the strongest and weakest phenotypes occurring for Mmp3 and Mmp1, respectively. By contrast, overexpression of each Mmp promoted fat body cell dissociation and ovary development, with the strongest stimulatory effects for Mmp3 overexpression and the weakest effects for Mmp1 overexpression. This is the first time to show that Mmps induce fat body cell dissociation in Lepidoptera, and we also hypothesize that Mmps-induced fat body cell dissociation is required for ovary development in this insect species. PMID- 30300620 TI - Mechanistic Study of Belinostat Oral Absorption From Spray-Dried Dispersions. AB - Spray-dried dispersions (SDDs) are an important technology for enhancing the oral bioavailability of poorly water-soluble drugs. To design an effective oral SDD formulation, the key rate-determining step(s) for oral drug absorption must be understood. This work combined in vivo and in vitro tests with in silico modeling to identify the rate-determining steps for oral absorption of belinostat SDDs made with 3 different polymers (PVP K30, PVP VA64, and HPMCAS-M). The goal was developing a belinostat SDD formulation that maximizes oral bioavailability (ideally matching the performance of a belinostat oral solution) and defining critical performance attributes for formulation optimization. The in vivo pharmacokinetic study with beagle dogs demonstrated that 1 of the 3 SDDs (PVP K30 SDD) matched the performance of the oral solution. In vitro data coupled with in silico modeling elucidated differences among the SDDs and supported the hypothesis that absorption of belinostat in the small intestine from the other 2 SDDs (PVP VA64 and HPMCAS-M) may be limited by dissolution rate or reduced drug activity (maximum concentration) in the presence of polymer. It was concluded that drug concentration in the stomach before emptying into the proximal intestine is a key factor for maximizing in vivo performance. PMID- 30300621 TI - Changes in the Solid State of Nicergoline, a Poorly Soluble Drug, Under Different Grinding and Environmental Conditions: Effect on Polymorphism and Dissolution. AB - Nicergoline native crystals (Form I) were subjected to different grinding methods for 15, 30, 45, and 60 min: Method A, grinding at 20 degrees C under air atmosphere; Method B, grinding in presence of liquid nitrogen under air atmosphere; Method C, grinding at 20 degrees C under nitrogen atmosphere; and Method D, grinding in presence of liquid nitrogen under nitrogen atmosphere. Scanning electron microscopy, differential scanning calorimetry, X-ray powder diffractometry, thermogravimetry, and infrared spectroscopy were used to follow changes in the particle size and in crystalline structures. Batches from Methods A and C underwent partial amorphization immediately after grinding; Form II was obtained by heating these partially amorphous forms or after spontaneous crystallization after 1 and 5 months storage. Method B promoted the hydration of nicergoline to a monohydrate form. Batch D was stable under grinding and neither amorphization nor hydration were observed. The best intrinsic dissolution rate was that of metastable Form II, followed by Form I, while the worst was that of the Method B monohydrate form. The slowest particle dissolution was observed for hydrated particles, because of the lowest IDR, while the most rapid was exhibited by batch D, because of the very small particle size. PMID- 30300622 TI - Skin secretion transcriptome remains in chromatographic fractions suitable for molecular cloning. AB - Traditional sources of mRNA for molecular cloning on amphibian skin secretion studies have been the frog's skin and skin secretions. Here, we demonstrate that mRNA isolated from chromatographic fractions of skin secretions is amenable for molecular cloning assays. We identified precursor sequences of the Arg0, Trp5, Leu8-bradykinin and six antimicrobial peptides of Pelophylax esculentus (Ranidae). These results show that both transcriptomic and peptidomic analyses can be performed with a single sample reducing in half the amount of starting skin secretion required. This is a significant advantage when working with endangered or very rare amphibian species, where minimal samples are available. PMID- 30300623 TI - Uncured PDMS inhibits myosin in vitro motility in a microfluidic flow cell. AB - The myosin motor powers cardiac contraction and is frequently implicated in hereditary heart disease by its mutation. Principal motor function characteristics include myosin unitary step size, duty cycle, and force-velocity relationship for translating actin under load. These characteristics are sometimes measured in vitro with a motility assay detecting fluorescent labeled actin filament gliding velocity over a planar array of surface immobilized myosin. Assay miniaturization in a polydimethylsiloxane/glass (PDMS/glass) hybrid microfluidic flow channel is an essential component to a small sample volume assay applicable to costly protein samples however the PDMS substrate dramatically inhibits myosin motility. Myosin in vitro motility in a PDMS/glass hybrid microfluidic flow cell was tested under a variety of conditions to identify and mitigate the effect of PDMS on myosin. Substantial contamination by unpolymerized species in the PDMS flow cells is shown to be the cause of myosin motility inhibition. Normal myosin motility recovers by either extended cell aging (~20 days) to allow more complete polymerization or by direct chemical extraction of the unpolymerized species from the polymer substrate. PDMS flow cell aging is the low cost alternative compatible with the other PDMS and glass modifications needed for in vitro myosin motility assaying.

AB - Breast cancer is a leading lethal gynecological cancer. Although many tumor markers and target genes have been studied in breast cancer, its incidence is increasing. Recently, the therapeutic effects of natural phytochemicals have been studied in various cancers as adjuvants. Chrysophanol is an anti-inflammatory, anti-angiogenetic, and anti-tumor anthraquinone but has not been widely studied in cancers. Here, we verified the anti-cancer effects and cellular mechanism of chrysophanol in human breast cancer cells (BT-474 and MCF-7). Chrysophanol selectively inhibited cell proliferation and induced apoptosis of breast cancer cells but not of normal mammary ductal epithelial cells, MCF-12A. Additionally, chrysophanol increased loss of mitochondrial membrane potential and cytosolic calcium levels to activate pro-apoptotic proteins, Bax, Bak, and cytochrome c, in both cell lines. Reactive oxygen species (ROS) overproduction by chrysophanol resulted in endoplasmic reticulum (ER) stress, leading to an increase in PERK, eIF2alpha, GADD153, and IRE1alpha levels in BT-474 and MCF-7 cells. These ER stress proteins increased by chrysophanol were repressed by co-treatment with N acetyl-L-cysteine, an ROS inhibitor. Western blotting showed that chrysophanol down-regulated ERK1/2, AKT, P70S6K, and S6 in both cell lines. However, P38 and JNK activities decreased in BT-474 cells and increased in MCF-7 cells. Additionally, co-treatment with ERK1/2 (U0126) or an AKT inhibitor (LY294002) plus chrysophanol reduced cell proliferation, whereas P38 (SB203580) and a JNK inhibitor (SP600125) showed synergic effects only in BT-474 cell lines. These results show that chrysophanol has anti-cancer effects on human breast cancer cells, specifically through mitochondrial apoptosis and ER stress induction.

PMID- 30300629 TI - The saprophytic fungus Fusarium solani increases the insecticidal efficacy of the entomopathogenic nematode Steinernema diaprepesi. AB - In two field surveys, high proportions of Galleria mellonella L. (Lepidoptera: Pyralidae) sentinel larval cadavers were infected by Fusarium solani without evidence of concomitant entomopathogenic nematode (EPN) or entomopathogenic fungus (EPF) reproduction. Because F. solani is not considered entomopathogenic, the survey suggested the possibility that F. solani competes with EPNs. We tested the hypotheses that F. solani attracts the EPN, Steinernema diaprepesi, to facilitate infection of Diaprepes root weevils (Diaprepes abbreviatus L.) and thereafter competes with the nematode in the insect cadaver. In two-choice olfactometer assays where one side was treated with F. solani mycelia and conidia, juvenile S. diaprepesi were attracted to the fungus, in either raw soil, or in autoclaved soil in the presence or absence of insects. However, this attraction was attenuated as the habitat became more complex, by using raw soil in combination with insect larvae. Fusarium oxysporum did not recruit the nematode. When soil microcosms were tested with F. solani conidia and S. diaprepesi, the concomitant infection increased the mortality of the insect (P = 0.02) to 83%, compared to 58% and 0% mortality when nematodes or fungi were individually applied, respectively. Concomitant inoculation also increased the number of cadavers that supported nematode reproduction and increased the population density of fungus in soil. The number of IJs entering the host insect was not affected by F. solani. These results support the possibility that F. solani can facilitate the insecticidal efficiency of S. diaprepesi in order to exploit the resources in the cadaver. PMID- 30300630 TI - Synergistic effects of pathogen and pesticide exposure on honey bee (Apis mellifera) survival and immunity. AB - Declines in native insect pollinator populations and substantial losses in managed honey bees have been reported on a global scale and become a widespread concern because of the importance of these insects for human food production and ecosystem stability. Several potential factors have been studied as possible causes of declining pollinator health, such as parasites and pathogens, exposure to agricultural pesticides, habitat loss and/or climate change. More recently, a combination of these factors rather than a single cause have been blamed for observed pollinator losses, but field studies of such interactions are challenging, especially in the presence of confounding environmental stressors. We therefore examined the impact of single and combined stressors on the honey bee (Apis mellifera) in a generally healthy Australian population. We exposed workers during their larval development and drones until they reached sexual maturity to the neonicotinoid pesticide Thiamethoxam, at concentrations more than 20 times lower than we initially measured in the field, the microsporidian gut pathogen Nosema apis or both stressors at the same time. We found that simultaneous exposure significantly reduced bee health. We observed a substantial increase in mortality and a reduction of immunocompetence in workers exposed to both the pathogen and the pesticide. We conclude that the exposure of generally healthy bees to multiple environmental stressors results in synergistic effects where the effects are expected to negatively impact performance and could be sufficient to trigger colony collapse. We found that the vast majority of males did not survive to sexual maturity after exposure to very low levels of Thiamethoxam. This would not only reduce the reproductive success of individual colonies, but can also impact gene flow and genetic diversity at the population level, which are both known as key components of honey bee health. PMID- 30300631 TI - Molecular and structural assessment of microsporidia infecting daphnids: The "obtusa-like" microsporidia, a branch of the monophyletic Agglomeratidae clade, with the establishment of a new genus Conglomerata. AB - Microsporidia (Opisthosporidia, Microsporidia) are frequent parasites of planktonic cladocerans, including Daphnia (Crustacea, Branchiopoda). Analysis of available molecular data (ITS region and partial ssu and lsu rDNA) of these parasites indicates that many microsporidia infecting daphnids have a common ancestor and represent a large clade, which splits during evolution into a number of well supported subclades. These subclades are cytologically different but may be most conveniently characterised by their specific ITS barcode. We have analysed one of these subclades and we describe a new microsporidian genus and species combination, and assemble a large group of structurally indistinguishable microsporidian parasites that infect adipose cells of their hosts and form pyriform spores of a certain type ("obtuse spores"). Obtuse spores are non infectious by feeding to their crustacean hosts and it is plausible that microsporidia forming them actually are parasites of insects with aquatic larval stages, with an obligate two-host life cycle, analogous to the Amblyospora life cycle involving copepods and mosquitoes. PMID- 30300632 TI - Clinical Utility of Prostate and Tumor Volume-Related Parameters Following Radical Prostatectomy for Localized Prostate Cancer. AB - PURPOSE: To evaluate whether prediction of biochemical recurrence (BCR) after radical prostatectomy (RP) is enhanced by any of six parameters: prostate volume, total tumor volume (TV), high grade TV, ratio of high grade TV to TV, ratio of TV to prostate volume and/or ratio of high grade TV to prostate volume. MATERIALS AND METHODS: 1261 patients who underwent RP over a 3 year period had tumor maps constructed with Gleason pattern denoted as either low (3) or high (4 or 5) and volumetric data generated using commercially available software. Univariate Cox regression models were used to assess whether each volume-related parameters was associated with BCR after RP. A multivariable Cox regression "base model" (age, PSA, Gleason score/grade group, pathologic stage and margin status) was compared with 6 additional models (base model + each volume-related parameter) to evaluate enhancement in predictive accuracy. Decision curve analysis was performed to determine the clinical utility of parameters that enhanced predictive accuracy. RESULTS: On univariate analysis, each parameter was significantly associated with BCR except prostate volume. Predictive accuracy of multivariable base model was high (c-index=0.861). Adding volume-related parameters marginally enhanced discrimination. Decision curve analysis failed to show added benefit even for high grade TV/TV (parameter with highest discriminative improvement). CONCLUSIONS: Tumor volume-related parameters are significantly associated with BCR, but do not add important discrimination to standard clinicopathologic variables for BCR prediction nor provide benefit across a range of clinically relevant decision thresholds. Volume-related measurement is not warranted in routine pathologic evaluation and reporting.

AB - Responding to aversive and rewarding stimuli is essential to survival. The ventral pallidum (VP) is a critical node in the mesolimbic network, being the primary output of the nucleus accumbens and projecting to the lateral habenula (LHb) and ventral tegmental area (VTA). The VP is thus poised to modulate the habenula-tegmental circuitry and contribute to processing both rewarding and aversive stimuli. Here, we integrate human functional imaging, behavioral pharmacology in rodents, and recent optogenetic circuit dissection studies of the VP with a focus on the role of the neurochemically-distinct subpopulations in aversion processing. These recent results support a model in which glutamatergic VP neurons play a unique role in aversion processing, while canonical GABAergic VP neurons promote reinforcement and encode the hedonic value of reward. Genetic ablation of glutamatergic, but not GABAergic VP neurons abolishes devaluation of natural reward (sucrose) by pairing with an aversive stimulus (lithium chloride injection). Both of these populations modulate activity throughout the LHb and VTA, which is necessary for expression of adaptive behavior in response to rewarding or aversive stimuli. Future work will address how neuromodulators such as endogenous opioids or dopamine shape function and plasticity within these distinct populations of VP neurons, when these subpopulations are engaged during learning responses to rewarding and aversive stimuli, and how their activity is altered in models of reward-related disorders. Answering these questions will be necessary to understand the basis and ultimately develop targeted therapies for disorders of reward/aversion processing, such as affective, chronic pain and substance use disorders. PMID- 30300635 TI - Dopamine signals related to appetitive and aversive events in paradigms that manipulate reward and avoidability. AB - Using environmental cues to acquire good and avoid harmful things is critical for survival. Rewarding and aversive outcomes both drive behavior through reinforcement learning and sometimes occur together in the environment, but it remains unclear how these signals are encoded within the brain and if signals for positive and negative reinforcement are encoded similarly. Recent studies demonstrate that the dopaminergic system and interconnected brain regions process both positive and negative reinforcement necessary for approach and avoidance behaviors, respectively. Here, we review these data with a special focus on behavioral paradigms that manipulate both expected reward and the avoidability of aversive events to reveal neural correlates related to value, prediction error encoding, motivation, and salience. PMID- 30300636 TI - A competitive model for striatal action selection. AB - The direct and indirect pathway striatal medium spiny neurons (dMSNs and iMSNs) have long been linked to action selection, but the precise roles of these neurons in this process remain unclear. Here, we review different models of striatal pathway function, focusing on the classic "go/no-go" model which posits that dMSNs facilitate movement while iMSNs inhibit movement, and the "complementary" model, which argues that dMSNs facilitate the selection of specific actions while iMSNs inhibit potentially conflicting actions. We discuss the merits and shortcomings of these models and propose a "competitive" model to explain the contribution of these two pathways to behavior. The "competitive" model argues that rather than inhibiting conflicting actions, iMSNs are tuned to the same actions that dMSNs facilitate, and the two populations "compete" to determine the animal's behavioral response. This model provides a theoretical explanation for how these pathways work together to select actions. In addition, it provides a link between action selection and behavioral reinforcement, via modulating synaptic strength at inputs onto dMSNs and iMSNs. Finally, this model makes predictions about how imbalances in the activity of these pathways may underlie behavioral traits associated with psychiatric disorders. Understanding the roles of these striatal pathways in action selection may help to clarify the neuronal mechanisms of decision-making under normal and pathological conditions. PMID- 30300637 TI - Evaluation of performance monitoring ERPs through difficulty manipulation in a response-feedback paradigm. AB - Performance monitoring is an amply studied function, since it is of major importance in carrying out actions in our everyday life. No consensus has been reached on the functional role and the relationship between each event-related potential (ERP) characterizing this function. In this study, we used a modified version of the flanker task, measuring the impact of task difficulty on the amplitudes of response-locked and feedback-locked performance monitoring ERPs in a single trial. We observed a functional differentiation between fronto-central (ERN/CRN and FRN) and centro-parietal (Pe/Pc and P300) components: the former seem to be only sensitive to accuracy, whereas the latter seem to be mainly modulated by task difficulty. The use of a surface Laplacian transformation, estimating current source density, on our data also supported an effect of difficulty on centro-parietal response-locked and feedback-locked ERPs. This technique allowed the spatial resolution to be improved and provided clarity, associated with the difficulty manipulation, and the activity of response-locked and feedback-locked performance monitoring ERPs. PMID- 30300638 TI - Uniportal Lung Cancer Surgery: The State of the Evidence. AB - BACKGROUND: Uniportal video-assisted thoracic surgery (VATS) has generated much attention in recent years, but questions remain regarding the adequacy of evidence to support its use in lung cancer surgery. This review aims to explore what the currently published literature suggests the role of the uniportal approach may be, and to critically appraise that literature. METHODS: A systematic review was conducted using the OVID Medline database to identify articles related to uniportal VATS. Articles were selected for review on the basis of ability to provide original clinical data on the role of uniportal VATS for lung cancer surgery. RESULTS: Literature searching reveals that only a minority of the publications on uniportal VATS provide original clinical data. Twenty-two articles were selected for review, including 9 case series and 13 comparative studies. No concerns about the safety of the uniportal VATS have been noted. Some but not all comparative studies provide data suggesting that uniportal VATS may hold advantages over multiportal VATS in some simple clinical outcomes (such as reduced lengths of stay and post-operative pain). However, the quantity and quality of the evidence thus far is limited. CONCLUSIONS: It remains premature to declare superiority for uniportal VATS in lung cancer surgery. A higher level of evidence is needed, especially in investigating objective benefits and treatment efficacy of the single incision approach.

PMID- 30300642 TI - Two ventricles are not better than one in the Fontan circulation: equivalent late outcomes. AB - BACKGROUND: A subset of Fontan patients has two adequate-sized ventricles, but an anatomic biventricular circulation cannot be achieved due to complex morphology or technical reasons. We sought to determine whether these two-ventricle Fontan patients had superior outcomes compared to those with a single ventricle. METHODS: A bi-national Registry of Fontan patients (n=1377) was analysed to identify Fontan patients with two adequate ventricles. This cohort was compared with single ventricle Fontan patients. The primary end-point was a composite endpoint called 'Fontan failure' encompassing death, transplant, Fontan takedown or conversion, protein-losing enteropathy, plastic bronchitis or NYHA III or IV functional class. RESULTS: A total of 79 Fontan patients with two adequate ventricles (2V) were compared with 1291 single ventricle (1V) Fontan patients. Median follow-up for the entire cohort was 11.5 years (IQR 5.1-18.8 years). There was no difference in unadjusted 15-year freedom from Fontan failure (2V: 81% (95% CI 69-94%) vs. 1V: 86% (83-88%), p= 0.4). Propensity-score matching for potential confounding factors yielded 75 two-ventricle Fontan patients being matched with 604 single ventricle Fontan patients, in which 15-year freedom from Fontan failure was also not different (2V: 79% (67-94%) vs 1V: 87% (84-91%), p=0.3). CONCLUSIONS: The two-ventricle Fontan circulation does not have better outcomes compared to the single ventricle Fontan. Late outcomes may depend more on other characteristics of the Fontan circulation. This finding is relevant when the Fontan procedure is being considered as an alternative to anatomic repair in complex two ventricle morphologies.

AB - BACKGROUND: Society of Thoracic Surgeons guidelines recommend surgical ablation (SA) at the time of concomitant mitral operations, aortic valve replacement, coronary artery bypass grafting (CABG), and AVR plus CABG for patients in atrial fibrillation (AF). The goal of this analysis was to assess the influence of SA on long term survival. METHODS: A retrospective analysis of 20,407 consecutive CABG or valve procedures from 2008-2015 among 7 centers reporting to a prospectively maintained clinical registry was conducted. Patients undergoing surgery with documented pre-operative AF were included (n=2,740). Patients receiving SA were compared to those receiving no SA. The primary endpoint was all-cause mortality. Secondary endpoints included in-hospital morbidity and mortality. RESULTS: The frequency of SA was 23.1% (n=634), and there was an increase in the rate of SA over the study period (p<0.001). Concomitant SA was performed in: 16.2% of CABG, 30.6% of valve, and 24.3% of valve plus CABG cases. There was a significant improvement in unadjusted survival among patients undergoing SA (HR 0.54, 95%CI=0.42-0.70). Moreover, there were no differences in post-operative complications. SA patients did have longer bypass times (p<0.001) but a shorter overall length of stay (p<0.001). After risk adjustment, SA patients had an improved 5-year survival (HR 0.69, 95%CI=0.51-0.92), and the effect was observed across all operations. CONCLUSIONS: In a multi-center cohort of patients with AF, concomitant SA resulted in significantly improved long-term survival across CABG, valve, and valve plus CABG patients. These findings support current STS guidelines recommending broader application of concomitant SA. PMID- 30300645 TI - LMIC and US trainees benefit from the global health educator.

AB - The defences used by organisms against predators display a great degree of variability. Defence phenotypes can differ substantially among individuals of the same species, and a single individual can itself deploy a variety of defences. Here, we use a mathematical model that includes mutation and selection to understand the evolutionary origin of this variability in a population of a species that deploys defences sequentially ("first" and "second" defences). Typically, the first defence evolves to have lower variance, i.e. appears more closely accumulated around the ideal phenotype, than the second defence (even when the breaching the first defence incurs more fitness loss than breaching the second defence with the other parameters the same for both defences). However, if the first defence is much less effective in repelling predators, or is much less tolerant of deviation from the ideal phenotype, then the first defence can evolve to have higher variance than the second. Other factors like mutation strength and the losses in the fitness when each defence fails also influence the defence variance. Larger mutation rate incurs larger equilibrium variances, and when the comparative importance in fitness of one defence increases, then the ratio between the variances of this defence and the other defence decreases. Sequentially acting defences are found in many organisms, so we encourage empirical research to test our theoretical predictions. PMID- 30300648 TI - Viral replication modes in single-peak fitness landscapes: A dynamical systems analysis. AB - Positive-sense, single-stranded RNA viruses are important pathogens infecting almost all types of organisms. Experimental evidence from distributions of mutations and from viral RNA amplification suggest that these pathogens may follow different RNA replication modes, ranging from the stamping machine replication (SMR) to the geometric replication (GR) mode. Although previous theoretical work has focused on the evolutionary dynamics of RNA viruses amplifying their genomes with different strategies, little is known in terms of the bifurcations and transitions involving the so-called error threshold (mutation-induced dominance of mutants) and lethal mutagenesis (extinction of all sequences due to mutation accumulation and demographic stochasticity). Here we analyze a dynamical system describing the intracellular amplification of viral RNA genomes evolving on a single-peak fitness landscape focusing on three cases considering neutral, deleterious, and lethal mutants. We analytically derive the critical mutation rates causing lethal mutagenesis and error threshold, governed by transcritical bifurcations that depend on parameters alpha (parameter introducing the mode of replication), replicative fitness of mutants (k1), and on the spontaneous degradation rates of the sequences (epsilon). Our results relate the error catastrophe with lethal mutagenesis in a model with continuous populations of viral genomes. The former case involves dominance of the mutant sequences, while the latter, a deterministic extinction of the viral RNAs during replication due to increased mutation. For the lethal case the critical mutation rate involving lethal mutagenesis is MUc=1-E/alpha. Here, the SMR involves lower critical mutation rates, being the system more robust to lethal mutagenesis replicating closer to the GR mode. This result is also found for the neutral and deleterious cases, but for these later cases lethal mutagenesis can shift to the error threshold once the replication mode surpasses a threshold given by alpha=epsilon/k1. PMID- 30300649 TI - Wall stress enhanced exocytosis of extracellular vesicles as a possible mechanism of left-right symmetry-breaking in vertebrate development. AB - In certain vertebrate species, the developing embryo breaks left-right symmetry in a transient organising structure: the "Left-Right Organiser" (LRO) known as the "node" in mice, and "Kupffer's vesicle" in fish. Directional cilia-driven flow is integral to this symmetry-breaking process, however the mechanism by which this flow is translated into an asymmetric signal remains contested; the principal theories are either flow transport of vesicles containing morphogens, or flow mechanosensing by cilia. Whilst some recent work favours the morphogen theory, other findings seem to support mechanosensing. In this study, we consider a hypothesis whereby the cilia themselves drive the release of morphogen-carrying extracellular vesicles (EVs) into the LRO; namely, that fluid stresses on the cell membrane induce/enhance exocytosis of EVs. Using a mathematical model, we calculate significant wall normal and shear stresses for a range of typical cilium parameter values comparable to levels capable of enhancing exocytosis. This mechanism may be able to reconcile the apparently conflicting experimental evidence. PMID- 30300650 TI - Complex interaction of resource availability, life-history and demography determines the dynamics and stability of stage-structured populations. AB - The dynamics of stage-structured populations facing stage-specific variability in resource availability and/or demographic factors like unequal sex-ratios, remains poorly understood. We addressed these issues using a stage-structured individual based model that incorporates life-history parameters common to many holometabolous insects. The model was calibrated using time series data from a 49 generation experiment on laboratory populations of Drosophila melanogaster, subjected to four different combinations of larval and adult nutritional levels. The model was able to capture multiple qualitative and quantitative aspects of the empirical time series across three independent studies. We then simulated the model to explore the interaction of various life-history parameters and nutritional levels in determining population stability. In all nutritional regimes, constancy stability of the populations was reduced upon increasing egg hatchability, critical mass, and proportion of body resource allocated to female fecundity. However, the effects of increasing sensitivity of female-fecundity to adult density on constancy stability varied across nutrition regimes. The effects of unequal sex-ratio and sex-specific culling were greatly influenced by fecundity but not by levels of juvenile nutrition. Finally, we investigated the implications of some of these insights on the efficiency of the widely-used pest control method, the Sterile Insect Technique (SIT). We show that increasing the amount of juvenile food had no effects on SIT efficiency when the density independent fecundity is low, but reduces SIT efficiency when the density independent fecundity is high.

AB - BACKGROUND: Timing and stability of the sleep-wake cycle are potential modifiable risk factors for cardiometabolic disease. The aim of this study was to evaluate the relationship between objective measures of sleep-wake timing and stability with cardiometabolic disease risk. METHODS: In this multicenter, cross-sectional, population-based study, actigraphy data were obtained from the 2,156 adults, aged 18 to 64 years, recruited from the Sueno ancillary study of the Hispanic Community Health Study/Study of Latinos (2010-2013). These data were correlated with measures of cardiometabolic disease risk, including systolic and diastolic BPs, homeostatic assessment of insulin resistance, glycosylated hemoglobin, BMI, and hypertension and diabetes status. RESULTS: Each 10% decrease in interdaily stability was associated with a 3.0% absolute increase in the prevalence of hypertension (95% CI, 0.6-5.3; P < .05), an increase in systolic BP by 0.78 mm Hg (95% CI, 0.12-1.45; P < .05) and an increase in diastolic BP by 0.80 mm Hg (95% CI, 0.28-1.32; P < .05). In addition, delaying the midpoint of sleep by 1 h was associated with an increase in systolic BP by 0.73 mm Hg (95% CI, 0.30-1.16; P < .01) and diastolic BP by 0.53 mm Hg (95% CI, 0.17-0.90; P < .01). These associations were not significant after adjusting for shift work status. No association was found between interdaily stability or sleep timing and diabetes, BMI, or insulin resistance. CONCLUSIONS: These results suggest that beyond sleep duration, the timing and regularity of sleep-wake schedules are related to hypertension prevalence and BP. PMID- 30300653 TI - Validation of the Incremental Shuttle Walk Test as a Clinical End Point in Bronchiectasis. AB - BACKGROUND: A validated clinical end point is needed to assess response to therapies in bronchiectasis. OBJECTIVES: The goal of this study was to assess the reliability, validity, and responsiveness of the incremental shuttle walk test (ISWT) as a clinical end point in bronchiectasis. METHODS: In clinically stable patients (n = 30), the ISWT was performed twice, 6 months apart. Correlation between the St. George's Respiratory Questionnaire (SGRQ) and the ISWT (n = 94) was performed. The 1-year gentamicin study was reanalyzed to assess the area under the curve (percent change of ISWT with a >= 4 unit improvement in total SGRQ). ISWT was performed prior to and following 14 days of antibiotics for an exacerbation (94 oral courses and 30 IV courses, n = 124) and reanalysis of the 1 year gentamicin study (n = 57). RESULTS: The ISWT did not significantly change over 6 months while clinically stable. The ISWT correlated inversely with the SGRQ (rs = -0.60; P < .0001), Bronchiectasis Severity Index score (rs = -0.44; P < .0001), and sedentary time (rs = -0.48; P = .0007) but correlated with physical activity (rs = 0.42; P = .004). The area under the curve for percent change in ISWT with >= 4 unit improvement in SGRQ was 0.79 (95% CI, 0.66-0.91; P = .001). A threshold of 5% improvement in the ISWT had a 92% sensitivity but 50% specificity, and from the responsiveness studies would capture 73% of all patients. CONCLUSIONS: This study confirmed the ISWT to be reliable, valid, and responsive to change in patients with bronchiectasis. The authors propose that a minimum clinically important difference of 5% improvement in the ISWT would be a useful objective end point to assess therapies in bronchiectasis. PMID- 30300654 TI - Differential effects of high-fat diets before pregnancy and/or during pregnancy on fetal growth development. AB - AIMS: The aim of the study was to investigate the effects of high-fat diets before pregnancy and/or during pregnancy on fetal development. MAIN METHODS: Female mice were fed with standard diets (SD) or high-fat diets (HFD). After 12 weeks, females were mated. In the SD + SD and HFD + SD groups, pregnant mice were fed with standard diets. In the SD + HFD and HFD + HFD groups, pregnant mice were fed with high-fat diets. All pregnant mice were sacrificed on gestational day (GD) 16. KEY FINDINGS: Fetal weight and crown-rump length were increased in SD + HFD-fed mice, whereas were decreased in HFD + SD-fed mice. The levels of CRP and TNF-alpha in maternal serum and amniotic fluid were elevated in all HFD-fed mice. Placenta weight was elevated in SD + HFD-fed but not in HFD + SD-fed mice. Blood sinusoid areas, and the number of Ki67-positive cells, a marker of cell proliferation, were elevated in placental labyrinth layer of SD + HFD-fed mice, but decreased in HFD + SD-fed mice. Finally, placental Fatp1, a fatty acid transporter gene, was up-regulated in SD + HFD-fed mice. By contrary, placental Fatp1, and Snat2, an amino acid transporter, were down-regulated in HFD + SD-fed mice. Moreover, the levels of placental FATP4 and SNAT2 were up-regulated in SD + HFD-fed mice. SIGNIFICANCE: HFD before pregnancy and HFD during pregnancy differentially disturb fetal growth development. HFD before pregnancy-induced fetal SGA might be partially attributed to inflammatory cytokines and mediators derived from maternal adipose tissue. By contrary, HFD during pregnancy-induced fetal overweight may be partially attributed to the increase of placental nutrient transport capacity. PMID- 30300652 TI - VTE Risk Profiles and Prophylaxis in Medical and Surgical Inpatients: The Identification of Chinese Hospitalized Patients' Risk Profile for Venous Thromboembolism (DissolVE-2)-A Cross-sectional Study. AB - BACKGROUND: Limited data exist on VTE risk and prophylaxis in Chinese inpatients. The Identification of Chinese Hospitalized Patients' Risk Profile for Venous Thromboembolism-2 (DissolVE-2), a nationwide, multicenter, cross-sectional study, was therefore designed to investigate prevalence of VTE risks and evaluate VTE prophylaxis implementation compliant with the latest prophylaxis guidelines (American College of Chest Physicians [CHEST], 9th edition). METHODS: Adults admitted (>= 72 h) to 60 urban, tertiary Chinese hospitals due to acute medical conditions or surgery from March to September 2016 were assessed for VTE risk. Risk assessments were made by using the Padua Prediction Scoring or Caprini Risk Assessment model, risk factors, and prophylaxis based on the CHEST guidelines, 9th edition. RESULTS: A total of 13,609 patients (6,986 surgical and 6,623 medical) were analyzed. VTE risk in surgical inpatients was categorized as low (13.9%; 95% CI, 13.1-14.7), moderate (32.7%; 95% CI, 31.6-33.8), and high (53.4%; 95% CI, 52.2-54.6); risk in medical patients was categorized as low (63.4%; 95% CI, 62.2-64.6) and high (36.6%; 95% CI, 35.4-37.8). Major risk factors in surgical and medical patients were major open surgery (52.6%) and acute infection (42.2%), respectively. Overall rate of any prophylaxis and appropriate prophylactic method was 14.3% (19.0% vs 9.3%) and 10.3% (11.8% vs 6.0%) in surgical and medical patients. CONCLUSIONS: A large proportion of hospitalized patients reported VTE risk and low rate of CHEST-recommended prophylaxis. The data highlight the insufficient management of VTE risk and show the great potential for improving physicians' awareness and current practices across China.

PMID- 30300655 TI - Effect of valproic acid alone or combined with low dose gamma irradiation in modulating PTZ-induced convulsions in rats involving AKT/m-TOR pathway. AB - AIM: The current study evaluates the anticonvulsant effect of valproic acid (VPA) alone or combined with low dose gamma-irradiation (LDR) against pentylenetetrazol induced convulsions in rats. MATERIAL AND METHODS: Five groups of rats were used, group I served as normal control, group II served as PTZ- control and the other three groups were pretreated with single LDR(o.5 Gy), VPA(150 mg/kg i.p.5 days) and VPA with LDR respectively before PTZ injection. Racine score, latency and duration of convulsions were assessed. Evaluation of brain neurotransmitters (glutamate and GABA) as well as AKT/m-TOR pathway (protein kinase B [AKT], mammalian target of rapamycin [m-TOR], protein S6 and caspase 3). Measurement of oxidative stress (Malondialdehyde, glutathione and nitric oxide) was carried out. Histopathological examinations of hippocampi were done. KEY FINDINGS: PTZ resulted in behavioural changes (high Racine score, long seizure duration and short latency).PTZ enhanced oxidative stress state (high MDA and NO, as well as low GSH) compared to normal control. VPA alone or combined with LDR ameliorated, the convulsions and caused significant improvement in behavioural changes and other tested parameters compared to normal control. Histopathological examination of hippocampi was carried out to adjoin the biochemical changes. Certain changes were observed after PTZ injection. However, normal pictures of the other tested groups. SIGNIFICANCE: The previously mentioned findings support that LDR purveyed novel anticonvulsant activity which could offer a possible contributor in the basic treatment of convulsions. This effect might be due to modulation of AkT/m TOR pathway, reduction of oxidative stress and modulation of neurotransmitters. PMID- 30300656 TI - Salidroside protects LPS-induced injury in human thyroid follicular epithelial cells by upregulation of MiR-27a. AB - AIMS: Hypothyroidism is a common endocrine disease without standard treatment. Salidroside (SAL) has various positive biological activities. In this study, experiments were performed to investigate whether SAL had protective effects on LPS-induced cell inflammatory injury. MAIN METHODS: The human thyroid follicular epithelial cells (Nthy-ori 3-1) stimulated by LPS were treated with SAL and/or transfected with miR-27a inhibitor. Cell viability and cell apoptosis were detect by Cell Counting Kit-8 assay and flow cytometry, respectively. The expression of Cyclin D1 and apoptosis-related proteins, Notch proteins and NF-kappaB pathways related proteins were all measured by western blot. The expression of miR-27a and inflammatory chemokines MCP-1, IL-6 and TNF-alpha was examined by qRT-PCR. The protein weight of MCP-1, IL-6 and TNF-alpha was detected by ELISA. KEY FINDINGS: LPS treatment induced cell injury by decreasing cell viability, and inducing cell apoptosis and inflammatory chemokines MCP-1, IL-6 and TNF-alpha. In addition, SAL alleviated LPS-induced cell injury by increasing cell viability, and decreasing cell apoptosis and inflammatory chemokines MCP-1, IL-6 and TNF-alpha. SAL upregulated miR-27a expression and further study showed that miR-27a downregulation impaired the protective effects of SAL. SAL downregulated the expression of Notch1/2, and phosphorylation of p65 and IkappaBalpha. SIGNIFICANCE: SAL protects against LPS-induced injury in human thyroid follicular epithelial cells by upregulation of miR-27a. This process might be via inactivating Notch and NF-kappaB pathways. PMID- 30300657 TI - Pulmonary arterial input impedance reflects the mechanical properties of pulmonary arterial remodeling in rats with pulmonary hypertension. AB - AIMS: Although pulmonary arterial remolding in pulmonary hypertension (PH) changes the mechanical properties of the pulmonary artery, most clinical studies have focused on static mechanical properties (resistance), and dynamic mechanical properties (compliance) have not attracted much attention. As arterial compliance plays a significant role in determining afterload of the right ventricle, we evaluated how PH changes the dynamic mechanical properties of the pulmonary artery using high-resolution, wideband input impedance (ZPA). We then examined how changes in ZPA account for arterial remodeling. Clarification of the relationship between arterial remodeling and ZPA could help evaluate arterial remodeling according to hemodynamics. MAIN METHODS: PH was induced in Sprague Dawley rats with an injection of Sugen5416 (20 mg/kg) and 3-week exposure to hypoxia (10% oxygen) (SuHx). ZPA was evaluated from pulmonary artery pressure and flow under irregular pacing. Pulmonary histology was examined at baseline and 1, 3, and 8 weeks (n = 7, each) after Sugen5416 injection. KEY FINDINGS: SuHx progressively increased pulmonary arterial pressure. ZPA findings indicated that SuHx progressively increased resistance (baseline: 9.3 +/- 3.6, SuHx1W: 20.7 +/- 7.9, SuHx3W: 48.8 +/- 6.9, SuHx8W: 62.9 +/- 17.8 mm Hg/mL/s, p < 0.01) and decreased compliance (baseline: 11.9 +/- 2.1, SuHx1W: 5.3 +/- 1.7, SuHx3W: 2.1 +/ 0.7, SuHx8W: 1.9 +/- 0.6 * 10-3 mL/mm Hg, p < 0.01). The time constant did not significantly change. The progressive reduction in compliance was closely associated with wall thickening of small pulmonary arteries. SIGNIFICANCE: The finding that changes in resistance were reciprocally associated with those in compliance indicates that resistant and compliant vessels are anatomically inseparable. The analysis of ZPA might help evaluate arterial remodeling in PH according to hemodynamics. PMID- 30300658 TI - Miniaturized whole-cell bacterial bioreporter assay for identification of quorum sensing interfering compounds. AB - The continuing emergence and spread of antibiotic-resistant bacteria is worrisome and new strategies to curb bacterial infections are being sought. The interference of bacterial quorum sensing (QS) signaling has been suggested as a prospective antivirulence strategy. The AI-2 QS system is present in multiple bacterial species and has been shown to be correlated with pathogenicity. To facilitate the discovery of novel compounds interfering with AI-2 QS, we established a high-throughput setup of whole-cell bioreporter assay, which can be performed in either 96- or 384-well format. Agonistic or antagonistic activities of the test compounds against Escherichia coli LsrB-type AI-2 QS system are monitored by measuring the level of beta-galactosidase expression. A control strain expressing beta-galactosidase in quorum sensing-independent manner is included into the assay for false-positive detection. PMID- 30300659 TI - Racial and Sociodemographic Differences of Semen Parameters Among US Men Undergoing a Semen Analysis. AB - OBJECTIVE: To characterize sociodemographic differences in semen parameters among US men undergoing a semen analysis. MATERIALS AND METHODS: Men who provided a semen sample were identified from insurance claims between 2007 and 2016. Differences in semen parameters were characterized according to age, race, education, and region. Mean semen parameters and proportions of men with suboptimal parameters were compared and risks of oligospermia and azoospermia were assessed by logistic regression. RESULTS: Of the 7263 men included, most men were white (55.1%), Hispanic (20.2%), or Asian (10.2%). Asians had the highest mean semen concentrations (69.2 * 106/mL), whereas blacks had the lowest (51.3 * 106/mL). Men from the Midwest were more likely to have oligospermia (odds ratio [OR] 1.62; 95% confidence interval [CI] 1.34-1.94), whereas men from the West were less likely (OR 0.82; 95% CI 0.82-0.94) when compared with men from South. An association between education and sperm concentration was observed. For example, men with a high school diploma or less were more likely to have oligospermia (OR 1.09; 95% CI 0.95-1.26), whereas men with at least a bachelor degree were less likely (OR 0.87; 95% CI 0.76-1.0) when compared with men with less than a bachelor degree. CONCLUSION: As we observed differences in semen quality based on sociodemographic factors, these findings may have clinical implications as relying on a single reference value when guiding infertile couples may be problematic given these variations. Further work is warranted to understand the etiology of such differences and determine if different normative reference values may apply for different populations. PMID- 30300660 TI - Robot-assisted Partial Nephrectomy: Is Routine Urinary Catheterization Still Mandatory in the Era of Enhanced Recovery? AB - OBJECTIVE: To assess the benefits and safety of noncatheterization during robot assisted partial nephrectomy within an enhanced recovery protocol. MATERIALS AND METHODS: A single-center retrospective comparative study was carried out of consecutive patients who underwent a robot-assisted partial nephrectomy between February 2015 and December 2017 within an early recovery program. The patients who received a urinary catheter were compared with those who did not in terms of postoperative complications, acute urinary retention rates, urinary tract infection rates, and lengths of hospital stay. RESULTS: Of the 145 patients who followed an early recovery program after robot-assisted partial nephrectomy in the study period, 96 received a urinary catheter and 49 did not. There was no significant difference between these 2 groups in terms of the rates of acute urinary retention (3% vs 6%, respectively; P = .393), urinary tract infection (3% vs 2%; P = .707), postoperative complications (14% vs 18%; P = .445), or readmissions within 30 days (8% vs 6%; P = .636). However, patients who did not receive a catheter had shorter initial and total (including readmissions) lengths of hospital stay (respectively 2.16 days vs 2.56 days; P = .058, and 2.27 days vs 3.40 days; P <.001). CONCLUSION: Our findings challenge the routine use of urinary catheterization during robot-assisted partial nephrectomies. Noncatheterization does not seem to increase the risk of postoperative urinary retention. Only catheterizing specific at-risk patients may prove beneficial. PMID- 30300661 TI - The effect of countermeasures against the reaction time based concealed information test on the P300 index of knowledge recognition: A combined RT and P300-based test. AB - Behavioral reaction time (RT) to key (probe) stimuli in a concealed information test (CIT) is usually greater than RT to irrelevant stimuli, and this difference has been utilized as a sign of recognition of concealed information. The ability to voluntarily increase irrelevant RT would appear to be an obvious countermeasure to the RT-based CIT. This study examined the effect of such countermeasure use on the simultaneously recorded P300 event related potentials. There were two blocks of trials in the present study, based on the 3-stimulus protocol. On the first trial block, half the participants were tested on concealed recognition of their phone numbers without a countermeasure. In the second block, this subset of participants were tested on their birth dates, while they applied a countermeasure consisting of the mental statement of the phrase "yes sir" prior to the button press signaling irrelevant stimulus. The other half of the subjects received the reverse order of stimulus categories. Results were that probe RT exceeded irrelevant RT in the first block, but that this relationship was reversed on the second block. In contrast, although the probe P300 exceeded the irrelevant P300 in the first block, this difference significantly increased in the second (RT countermeasure) block, leading to more detections based on P300. Thus, there was a differential effect of this novel countermeasure (directed at countering RT) on RT and P300, which actually led to improved detection with P300, suggesting that both measures might be profitably used in field applications. PMID- 30300662 TI - Frontal asymmetry predicts the incentive value of perceptual information. AB - Information has been suggested to convey incentive value mediated by dopaminergic systems similar to those implicated in extrinsic reward. Although the reward characteristics of information have received preliminary support by behavioral and fMRI findings, EEG correlates and individual differences have not yet been examined. In the current study, a novel perceptual paradigm was developed to probe the associations between anticipation of perceptual information and frontal electroencephalographic alpha asymmetry, i.e., a marker of approach motivation. Assuming individual differences in engaging with perceptual information, trait openness was examined as a moderator of the associations. One hundred and twenty participants viewed partly visible photos that were gradually uncovered. After they indicated state levels of confidence and curiosity, the photos were fully disclosed. During anticipation of the fully disclosed stimuli, left-lateralized asymmetry linearly increased with curiosity. Moreover, a curvilinear relationship between confidence and left-lateralized asymmetry emerged, suggesting enhanced motivational activation during medium levels of uncertainty. The curvilinear relationship was moderated by trait openness, indicating individual differences in the responsiveness to perceptual uncertainty. In summary, our findings provide novel empirical evidence for the incentive motivational value of information. PMID- 30300663 TI - The aversive brain system of teleosts: Implications for neuroscience and biological psychiatry. AB - Defensive behavior is a function of specific survival circuits, the "aversive brain system", that are thought to be conserved across vertebrates, and involve threat detection and the organization of defensive responses to reduce or eliminate threat. In mammals, these circuits involve amygdalar and hypothalamic subnuclei and midbrain circuits. The increased interest in teleost fishes as model organisms in neuroscience created a demand to understand which brain circuits are involved in defensive behavior. Telencephalic and habenular circuits represent a "forebrain circuit" for threat processing and organization of responses, being important to mounting appropriate coping responses. Specific hypothalamic circuits organize neuroendocrine and neurovegetative outputs, but are the less well-studied in fish. A "midbrain circuit" is represented by projections to interneurons in the optic tectum which mediate fast escape responses via projections to the central gray and/or the brainstem escape network. Threatening stimuli (especially visual stimuli) can bypass the "high road" and directly activate this system, initiating escape responses. Increased attention to these circuits in an evolutionary framework is still needed. PMID- 30300664 TI - Expression of amino acid transporter (LAT1 and 4F2hc) in pulmonary pleomorphic carcinoma. AB - Amino acid transporters are necessary for tumor growth, metastasis, and survival of various neoplasms; however, the clinicopathological significance of L-type amino acid transporter 1 (LAT1) and 4F2 cell surface antigen (4F2hc) in patients with pulmonary pleomorphic carcinoma (PPC) remains unknown. The aim of this study is to clarify the prognostic impact of these amino acid transporters in PPC. One hundred and five patients with surgically resected PPC were assessed by immunohistochemistry. The expression of LAT1 and 4F2hc, and Ki-67 labeling index were investigated using specimens of the resected tumors. LAT1 and 4F2hc were highly expressed in 35% and 53% of all patients (n = 105, P < .01), 25% and 48% of patients with an adenocarcinoma component (n = 48, P = .02), and 44% and 58% of patients with a non-adenocarcinoma component (n = 57, P = .18), respectively. A high LAT1 expression was significantly related to advanced disease, lymphatic permeation, tumor cell proliferation and 4F2hc expression. By multivariate analysis, LAT1 and 4F2hc were identified as significant independent markers for predicting a worse prognosis. LAT1 is highly expressed in PPC and high LAT1 expression can serve as a significant predictor linked to a worse prognosis in patients with PPC. PMID- 30300665 TI - Chronic inflammatory pain drives alcohol drinking in a sex-dependent manner for C57BL/6J mice. AB - Sex differences in chronic pain and alcohol abuse are not well understood. The development of rodent models is imperative for investigating the underlying changes behind these pathological states. In the present study, we investigated whether hind paw treatment with the inflammatory agent Complete Freund's Adjuvant (CFA) could generate hyperalgesia and alter alcohol consumption in male and female C57BL/6J mice. CFA treatment led to greater nociceptive sensitivity for both sexes in the Hargreaves test, and increased alcohol drinking for males in a continuous access two-bottle choice (CA2BC) paradigm. Regardless of treatment, female mice exhibited greater alcohol drinking than males. Following a 2-hour terminal drinking session, CFA treatment failed to produce changes in alcohol drinking, blood ethanol concentration (BEC), and plasma corticosterone (CORT) for both sexes. 2-hr alcohol consumption and CORT was higher in females than males, irrespective of CFA treatment. Taken together, these findings have established that male mice are more susceptible to escalations in alcohol drinking when undergoing pain, despite higher levels of total alcohol drinking and CORT in females. Furthermore, the exposure of CFA-treated C57BL/6J mice to the CA2BC drinking paradigm has proven to be a useful model for studying the relationship between chronic pain and alcohol abuse. Future applications of the CFA/CA2BC model should incorporate manipulations of stress signaling and other related biological systems to improve our mechanistic understanding of pain and alcohol interactions. PMID- 30300666 TI - Virulence genes and genetic diversity assessment of Shiga toxin-producing Escherichia coli O91 strains from cattle, beef and poultry products. AB - Shiga toxin-producing Escherichia coli (STEC) O91 has ranked in the top five of the non-O157 serogroups most frequently associated with human cases. In order to gain insight into the genetic diversity of O91 Latin American STEC strains, we analyzed their virulence properties and carried out a subtyping assay. A panel of 21 virulence genetic markers associated with human and animal infections was evaluated and the relatedness among strains was determined by a multiple-locus variable-number tandem repeats analysis (MLVA) comprising 9 VNTR loci. Twenty-two STEC O91 isolated from cattle and meat food and belonging to 5 serotypes (O91:H21, O91:H8, O91:H14, O91:H28, O91:H40) were studied. Eight virulence profiles were obtained for the O91 STEC strains: 4 for O91:H21 plus one for O91:H8, O91:H14, O91:H28 and O91:H40. All strains contained ehxA and lpfA0113 genes and only both stx1-positive strains lacked saa, which encodes the STEC autoagglutinating adhesin. Other genes involved in adhesion were detected: ehaA (91%), elfA and espP (86%), ecpA (82%) and, hcpA (77%). The gene encoding the cytolethal distending toxin type-V (CDT-V) was found only in O91:H8 and O91:H21, being present in the majority (89%) of strains of this last serotype. MLVA typing divided the total number of strains into 12 genotypes, and 9 of them were unique to a single strain. No association was observed between the virulence profiles and the source of the strains. Although they lack the eae gene, most of the strains have the genetic potential to adhere to host cells through other structures and possess cdt-V, which has been found in STEC strains involved in serious diseases. The MLVA showed clonal relatedness among strains isolated from cattle belonged to a same dairy farm and suggested that the same clone remains circulating throughout the year and, on the other hand, the need to increase the number of VNTR loci which could allow a higher discrimination among O91:H21 isolates. PMID- 30300667 TI - Identification of key pathways and metabolic fingerprints of longevity in C. elegans. AB - Impaired insulin/IGF-1 signaling (IIS) and caloric restriction (CR) prolong lifespan in the nematode C. elegans. However, a cross comparison of these longevity pathways using a multi-omics integration approach is lacking. In this study, we aimed to identify key pathways and metabolite fingerprints of longevity that are shared between IIS and CR worm models using multi-omics integration. We generated transcriptomics and metabolomics data from long-lived worm strains, i.e. daf-2 (impaired IIS) and eat-2 (CR model) and compared them with the wild type strain N2. Transcriptional profiling identified shared longevity signatures, such as an upregulation of lipid storage and defense responses, and downregulation of macromolecule synthesis and developmental processes. Metabolomics profiling identified an increase in the levels of glycerol-3P, adenine, xanthine, and AMP, and a decrease in the levels of the amino acid pool, as well as the C18:0, C17:1, C19:1, C20:0 and C22:0 fatty acids. After we integrated transcriptomics and metabolomics data based on the annotations in KEGG, our results highlighted increased amino acid metabolism and an upregulation of purine metabolism as a commonality between the two long-lived mutants. Overall, our findings point towards the existence of shared metabolic pathways that are likely important for lifespan extension and provide novel insights into potential regulators and metabolic fingerprints for longevity. PMID- 30300668 TI - Hepatic signalling disruption by pollutant Polychlorinated biphenyls in steatohepatitis. AB - BACKGROUND: Polychlorinated biphenyl-mediated steatohepatitis has been shown to be due in part to inhibition of epidermal growth factor receptor (EGFR) signalling. EGFR signalling regulates many facets of hepatocyte function, but it is unclear which other kinases and pathways are involved in the development of toxicant-associated steatohepatitis (TASH). METHODS: Comparative hepatic phosphoproteomic analysis was used to identify which kinases were affected by either PCB exposure (Aroclor 1260 mixture), high fat diet (HFD), or their interaction in a chronic exposure model of TASH. Cellular assays and western blot analysis were used to validate the phosphoproteomic findings. RESULTS: 1760 unique phosphorylated peptides were identified and of those 588 were significantly different. PCB exposure and dietary interaction promoted a near 25% reduction of hepatic phospho-peptides. Leptin and insulin signalling were pathways highly affected by PCB exposure and liver necrosis was a pathologic ontology over represented due to interaction between PCBs and a HFD. Casein kinase 2 (CK2), Extracellular regulated kinase (ERK), Protein kinase B (AKT), and Cyclin dependent kinase (CDK) activity were demonstrated to be downregulated after PCB exposure and this downregulation was exacerbated with a HFD. PCB exposure led to a loss of hepatic CK2 subunit expression limiting CK2 kinase activity and negatively regulating caspase-3 (CASP3). PCBs promoted secondary necrosis in vitro validating the latter observation. The loss of hepatic phosphoprotein signalling appeared to be due to decreased signal transduction rather than phosphatase upregulation. CONCLUSIONS: PCBs are signal disrupting chemicals that promote secondary necrosis through affecting a myriad of liver processes including metabolism and cellular maintenance. PCB exposure, particularly with interaction with a HFD greatly down-regulates the hepatic kinome. More data are needed on signalling disruption and its impact on liver health. PMID- 30300669 TI - Lifestyle segmentation and political ideology: Toward understanding beliefs and behavior about local food. AB - This research sought to better understand local food consumers and take steps to begin to identify how targeted messages could engage different groups. In order to accomplish these aims, data was collected through a survey mailed to a random sample of Wisconsin households with a final sample size of 577. These consumers were then segmented based on variables related to the food related lifestyle (FRL) and political ideology. Political ideology was included as it influences the media to which individuals pay attention, and how they interpret messages. Identified groups were further profiled with variables related to local food purchasing, frequency of shopping at farmers' markets and natural food stores, willingness to pay a premium for local food, perceptions related to local food, communication habits, and demographics. Five segments were identified, with three standing out as likely consumers of local produce. The liberal, "Adventurous" consumers showed a strong interest in local food, perceiving local food to be superior for its environmental benefits, among other reasons. The "Traditional" and "Rational" groups were not interested in local food for environmental reasons, and may find such messages unappealing. In order to engage these other groups, messages should address the high quality of local food, how it can be incorporated into traditional recipes (for the "Traditional" group), and ways to make local food affordable and convenient to buy (for the "Rational" group). PMID- 30300670 TI - The effects of reward and loss anticipation on attentional bias for reward related stimuli. AB - Attentional biases for reward-related (e.g., food, alcohol) cues are moderated by the expectation of imminent reward availability, but the psychological mechanisms that underlie this effect are unclear. We report two studies in which we investigated if effects of reward gain anticipation are specific to the type of reward that is anticipated, and if anticipation of loss has comparable effects to anticipation of reward gain. We used an eye tracking task to investigate the effects of anticipation of gain (experiment 1) or loss (experiment 2) of alcohol and chocolate on attentional bias for alcohol and chocolate pictures using full crossover designs; the effects of uncertain outcomes were investigated in both experiments. Results indicated robust effects of anticipation of reward gain and uncertainty on attentional bias that were outcome-specific (experiment 1). However attentional bias was not influenced by loss anticipation (experiment 2). Our findings demonstrate that anticipation of reward gain increases attentional bias for the type of reward that is anticipated, but anticipation of loss does not influence attentional bias. PMID- 30300671 TI - Vitamin E alleviates non-alcoholic fatty liver disease in phosphatidylethanolamine N-methyltransferase deficient mice. AB - Phosphatidylethanolamine N-methyltransferase (PEMT) converts phosphatidylethanolamine (PE) to phosphatidylcholine (PC), mainly in the liver. Pemt-/- mice are protected from high-fat diet (HFD)-induced obesity and insulin resistance, but develop severe non-alcoholic fatty liver disease (NAFLD) when fed a HFD, mostly due to impaired VLDL secretion. Oxidative stress is thought to be an essential factor in the progression from simple steatosis to steatohepatitis. Vitamin E is an antioxidant that has been clinically used to improve NAFLD pathology. Our aim was to determine whether supplementation of the diet with vitamin E could attenuate HFD-induced hepatic steatosis and its progression to NASH in Pemt-/- mice. Treatment with vitamin E (0.5 g/kg) for 3 weeks improved VLDL-TG secretion and normalized cholesterol metabolism, but failed to reduce hepatic TG content. Moreover, vitamin E treatment was able to reduce hepatic oxidative stress, inflammation and fibrosis. We also observed abnormal ceramide metabolism in Pemt-/- mice fed a HFD, with elevation of ceramides and other sphingolipids and higher expression of mRNAs for acid ceramidase (Asah1) and ceramide kinase (Cerk). Interestingly, vitamin E supplementation restored Asah1 and Cerk mRNA and sphingolipid levels. Together this study shows that vitamin E treatment efficiently prevented the progression from simple steatosis to steatohepatitis in mice lacking PEMT. PMID- 30300672 TI - Genome-wide analysis reveals the effects of artificial selection on production and meat quality traits in Qinchuan cattle. AB - A new strain of Qinchuan cattle (QNS) has been obtained after more than forty years of selective breeding, and it shows good performance and production traits. To characterize the genetic changes that have resulted from breeding, we sequenced 10 QNS and 10 of the original breed Qinchuan cattle (QCC) for the first time, with average of 12.5-fold depth. A total of 31,242,284 and 29,612,517 SNPs were identified in the QCC and QNS genomes, 47.81% and 44.36% of which were found to be novel, respectively. Furthermore, population structure analysis revealed the selection that these cattle had experienced. Then, 332 and 571 potential selected genes were obtained, associated with enhanced immunity and acclimatization in QCC (CD5, SMARCA2, CATHL2, etc.) and production or meat quality traits in QNS (PLCD3, MB, PPARGC1A, etc.). These results revealed the efforts of selective breeding for Chinese Qinchuan cattle, and will be helpful for future cattle breeding. PMID- 30300673 TI - Affect dynamics of facial EMG during continuous emotional experiences. AB - Emotional experiences are complex, multi-component processes that unfold over time. Accordingly, it is crucial to understand the temporal dynamics of these constituent components. Here we studied the dynamics of one of the core emotional systems, i.e. facial muscle activity, during continuous emotional experiences, elicited by movies. We found that transient zygomatic fluctuations were narrowly tuned to a positive emotional experience. During a positive but not a negative movie, zygomatic response patterns were consistent across participants, tracked with subjective ratings and co-varied with emotional dynamics. Corrugator activity evidenced a broader affective profile and larger individual variability. It was coordinated with tonic changes in emotional negativity and inversely coupled with transient changes in positive affect. Taken together, our results confirmed previous findings on the affective profiles of facial responses and extended them to temporal dynamics. They further uncovered important differences in temporal response characteristics of zygomatic and corrugator measures. PMID- 30300674 TI - Conflict-related medial frontal theta as an endophenotype for alcohol use disorder. AB - Diminished cognitive control in alcohol use disorder (AUD) is thought to be mediated by prefrontal cortex circuitry dysregulation. Research testing the relationship between AUD and specific cognitive control psychophysiological correlates, such as medial frontal (MF) theta-band EEG power, is scarce, and the etiology of this relationship is largely unknown. The current report tested relationship between pathological alcohol use through young adulthood and reduced conflict-related theta at age 29 in a large prospective population-based twin sample. Greater lifetime AUD symptomatology was associated with reduced MF theta power during response conflict, but not alpha-band visual attention processing. Follow-up analyses using cotwin control analysis and biometric modeling suggested that genetic influences, and not the consequences of sustained AUD symptomatology, explained the theta-AUD association. Results provide strong evidence that AUD is genetically related to diminished conflict-related MF theta, and advance MF theta as a promising electrophysiological correlate of AUD-related dysfunctional frontal circuitry. PMID- 30300675 TI - Melatonin as an adjunct to therapeutic hypothermia in a piglet model of neonatal encephalopathy: A translational study. AB - Therapeutic hypothermia is only partially protective for neonatal encephalopathy; there is an urgent need to develop treatments that augment cooling. Our objective was to assess safety, efficacy and pharmacokinetics of 5 and 15 mg/kg/24 h melatonin (proprietary formulation) administered at 2 h and 26 h after hypoxia ischemia (HI) with cooling in a piglet model. Following moderate cerebral HI, 30 piglets were eligible and randomized to: i) Hypothermia (33.5 degrees C, 2-26 h) and vehicle (HT + V;n = 13); b) HT and 5 mg/kg melatonin over 6 h at 2 h and 26 h after HI (HT + Mel-5;n = 4); c) HT and 15 mg/kg melatonin over 6 h at 2 h and 26 h after HI (HT + Mel-15;n = 13). Intensive care was maintained for 48 h; brain MRS was acquired and cell death (TUNEL) evaluated at 48 h. Comparing HT + V with HT + Mel-5 and HT + Mel-15, there was no difference in blood pressure or inotropic support needed, brain Lactate/N Acetylaspartate at 24 h and 48 h was similar, ATP/phosphate pool was higher for HT + Mel-15 versus HT + V at 24 h (p = 0.038) but not 48 h. A localized reduction in TUNEL positive cell death was observed in the sensorimotor cortex in the 15 mg/kg melatonin group (HT + Mel-15 versus HT + V; p < 0.003) but not in the 5 mg/kg melatonin group (HT + Mel-5 versus HT + V; p = 0.808). Putative therapeutic melatonin levels were reached 8 h after HI (104 increase from baseline; ~15-30 mg/l). Mean +/- SD peak plasma melatonin levels after the first infusion were 0.0014 +/- 0.0012 mg/l in the HT + V group, 3.97 +/- 1.53 mg/l in the HT + Mel-5 group and 16.8 +/- 8.3 mg/l in the HT + Mel-15 group. Protection was dose dependent; 15 mg/kg melatonin started 2 h after HI, given over 6 h, was well tolerated and augmented hypothermic protection in sensorimotor cortex. Earlier attainment of therapeutic plasma melatonin levels may optimize protection by targeting initial events of reperfusion injury. The time window for intervention with melatonin, as adjunct therapy with cooling, is likely to be narrow and should be considered in designing future clinical studies. PMID- 30300676 TI - Potentially missing data is considerably more frequent than definitely missing data: A methodological survey of 638 randomized controlled trials. AB - BACKGROUND: Missing data for the outcomes of participants in randomized controlled trials (RCTs) are a key element of risk of bias assessment. However, it is not always clear from RCT reports whether some categories of participants were followed-up or not (i.e., do or do not have missing data) nor how the RCT authors dealt with missing data in their analyses. OBJECTIVE: Our objectives were to describe how RCT authors: (1) report on different categories of participants that might have missing data; (2) handle these categories in the analysis; and (3) judge the risk of bias associated with missing data. METHODS: We surveyed all RCT reports included in 100 clinical intervention systematic reviews (SRs), half of which were Cochrane SRs. Eligible SRs reported a group-level meta-analysis of a patient-important dichotomous efficacy outcome, with a statistically significant effect estimate. Eleven reviewers, working in pairs, independently extracted data from the primary RCT reports included in the SRs. We pre-defined 19 categories of participants that might have missing data. Then, we classified these participants as follows: 'explicitly followed-up', 'explicitly not followed up' (i.e., definitely missing data), or 'unclear follow-up status' (i.e., potentially missing data). RESULTS: Of 638 eligible RCTs, 400 (63%) reported on at least one of the pre-defined categories of participants that might have missing data. The median percentage of participants who were explicitly not followed-up was 5.8% (IQR 2.2%-14.8%); it was 9.7% (4.1%-14.9%) for participants with unclear follow up status; and 11.7% (IQR 5.6%-23.7%) for participants who were explicitly not followed-up and with unclear follow up status. When authors explicitly reported not following-up participants, they most often conducted complete case analysis (54%). Most RCTs neither reported on missing data separately for different outcomes (99%) nor reported using a method for judging risk of bias associated with missing data (95%). CONCLUSION: 'Potentially missing data' is considerably more frequent than 'definitely missing data'. Adequate reporting of missing data will require development of explicit standards on which editors insist and to which RCT authors adhere. PMID- 30300677 TI - Electromechanics of polarized cell growth. AB - One of the most challenging questions in cell and developmental biology is how molecular signals are translated into mechanical forces that ultimately drive cell growth and motility. Despite an impressive body of literature demonstrating the importance of cytoskeletal and motor proteins as well as osmotic stresses for cell developmental mechanics, a host of dissenting evidence strongly suggests that these factors per se cannot explain growth mechanics even at the level of a single tip-growing cell. The present study addresses this issue by exploring fundamental interrelations between electrical and mechanical fields operating in cells. In the first instance, we employ a simplified but instructive model of a quiescent cell to demonstrate that even in a quasi-equilibrium state, ion transport processes are conditioned principally by mechanical tenets. Then we inquire into the electromechanical conjugacy in growing pollen tubes as biologically relevant and physically tractable developmental systems owing to their extensively characterized growth-associated ionic fluxes and strikingly polarized growth and morphology. A comprehensive analysis of the multifold stress pattern in the growing apices of pollen tubes suggests that tip-focused ionic fluxes passing through the polyelectrolyte-rich apical cytoplasm give rise to electrokinetic flows that actualize otherwise isotropic intracellular turgor into anisotropic stress field. The stress anisotropy can be then imparted from the apical cytoplasm to the abutting frontal cell wall to induce its local extension and directional cell growth. Converging lines of evidence explored in the concluding sections attest that tip-focused ionic fluxes and associated interfacial transport phenomena are not specific for pollen tubes but are also employed by a vast variety of algal, plant, fungal and animal cells, rendering their cytoplasmic stress fields essentially anisotropic and ultimately instrumental in cell shaping, growth and motility. PMID- 30300678 TI - Local and global dynamics in collective movements of embryonic cells. AB - Several important morphogenetic processes belong to the category of collective cell movements (CCM), by which we mean coordinated rearrangements of many neighboring cells. The causes of the dynamic order established during CCM are still unclear. We performed statistical studies of rates and angular orientations of cell rearrangements in two kinds of embryonic tissues, which we categorized as "committed" (in the sense of being capable of autonomous CCM) as opposed to "naive" tissues, which are those that require external forces in order to exhibit full scale CCM. In addition, we distinguished two types of cell rearrangements: first, those in which mutual cell-cell shifts characterizing the local dynamics (LD); and, second, those which moved in reference to common external coordinates (global dynamics, GD). We observed that in most cases LD rates deviated from normal distributions and do so by creating excesses of extensively converging and moderately diverging cells. In contrast, GD was characterized by nearly random behavior of slowly moving cells, combined with increased angular focusing of the fast cells trajectories as well as bimodal distribution of cell rates. When committed tissues were opposed by external mechanical forces, then they tended to preserve the inherent CCM patterns. On the other hand, the naive ones reacted by creating two orthogonal cells flows, one of these coinciding with the force direction. We consider CCM as a self-organizing process based on feedbacks between converging and diverging cell shifts, which is able to focus the trajectories imposed by external forces. PMID- 30300679 TI - PI3K pathway in prostate cancer: All resistant roads lead to PI3K. AB - The phosphoinositide 3-kinase (PI3K) pathway integrates multifarious environmental cues to regulate cell survival, growth, and metabolism. Hyperactivation of the PI3K pathway increases biological fitness by offering a high degree of adaptability to and resilience against diverse perturbations, thus conferring survival benefits on premalignant and transformed cells. In prostate cancer, the PI3K pathway is aberrantly activated by various genetic and epigenetic alterations and its hyperactivation is closely associated with a poor clinical outcome. In this review, we discuss the challenges encountered with clinically effective therapies targeting the PI3K pathway in prostate cancer, highlighting the clinical importance of combination therapies. In particular, we address how prostate cancer cells utilize the PI3K pathway for the development of resistance to a broad range of anticancer treatments. In addition, we describe the molecular mechanisms by which prostate cancer cells become resistant to PI3K pathway inhibitors. This review will be helpful in translating biological knowledge into therapeutic strategies for the treatment of prostate cancer and provide insight into overcoming therapeutic challenges associated with prostate cancer. PMID- 30300680 TI - Systemic L-buthionine-S-R-sulfoximine administration modulates glutathione homeostasis via NGF/TrkA and mTOR signaling in the cerebellum. AB - Glutathione (GSH) is an essential component of intracellular antioxidant systems that plays a primordial role in the protection of cells against oxidative stress, maintaining redox homeostasis and xenobiotic detoxification. GSH synthesis in the brain is limited by the availability of cysteine and glutamate. Cystine, the disulfide form of cysteine is transported into endothelial cells of the blood brain barrier (BBB) and astrocytes via the system xc-, which is composed of xCT and the heavy chain of 4F2 cell surface antigen (4F2hc). Cystine is reduced inside the cells and the L-type amino acid transporter 1 (LAT1) transports cysteine from the endothelial cells into the brain, cysteine is transported into the neurons through the excitatory amino acid transporter 3 (EAAT3), also known as excitatory amino acid carrier 1 (EAAC1). The mechanistic/mammalian target of rapamycin (mTOR) and neurotrophins can activate signaling pathways that modulate amino acid transporters for GSH synthesis. The present study found that systemic L-buthionine-S-R-sulfoximine (BSO) administration selectively altered GSH homeostasis and EAAT3 levels in the mice cerebellum. Intraperitoneal treatment of mice with 6 mmol/kg of BSO depleted GSH and GSSG in the liver at 2 h of treatment. The cerebellum, but not other brain regions, exhibited a redox response. The mTOR and the neuronal growth factor (NGF)/tropomyosin receptor kinase A (TrkA) signaling pathways were activated and lead to an increase in the protein levels of the EAAT3 transporter, which was linked to an increase in the GSH/GSSG ratio and GSH concentration in the cerebellum at 0.5 and 2 h, respectively. Therefore, the cerebellum responds to peripheral GSH depletion via activation of the mTOR and NGF/TrkA pathways, which increase the transport of cysteine for GSH synthesis. PMID- 30300682 TI - LGR5 acts as a target of miR-340-5p in the suppression of cell progression and drug resistance in breast cancer via Wnt/beta-catenin pathway. AB - Breast cancer is one of the most common malignant tumors among females. Recent studies demonstrated that microRNAs (miRNAs) played an important role in the regulation of tumor progression. In our present study, we firstly detected miR 340-5p expression in breast cancer cell lines and found lower expression of miR 340-5p in breast cancer cell lines (MCF-7, MDA-MB-231, BT-549, ZR-75-1) through qRT-PCR. Overexpressed miR-340-5p inhibited cell proliferation and drug resistance to docetaxel with enhanced cell apoptosis of breast cancer cells. Through bioinformatic prediction, we found that LGR5 was a potential target of miR-340-5p. LGR5 was highly expressed in breast cancer cells. Relative expression of LGR5 was negatively regulated by miR-340-5p. Knockdown of LGR5 also inhibited cell proliferation and drug resistance to docetaxel with enhanced cell apoptosis of breast cancer cells. Moreover, knockdown of LGR5 decreased the expression of beta-catenin, c-myc, Survivin. The activation of Wnt/beta-catenin pathway contracted the effects of LGR5 siRNA, indicating that LGR5 siRNA inhibited cell proliferation and drug resistance with induced apoptosis via suppressing Wnt/beta catenin signaling pathway in breast cancer. Taken together, our study demonstrated that overexpressed miR-340-5p inhibited cell proliferation and drug resistance with increased apoptosis of breast cancer cells through down regulating LGR5 expression via Wnt/beta-catenin pathway. The miR-340-5p/LGR5 axis may provide a new perspective for treatment for breast cancer. PMID- 30300681 TI - miR-323-3p regulates the steroidogenesis and cell apoptosis in polycystic ovary syndrome (PCOS) by targeting IGF-1. AB - Polycystic ovary syndrome (PCOS) is an endocrine and metabolic heterogeneous disorder. The incidence of which reaches 5% to 10% among reproductive-age women. Abnormal folliculogenesis is considered to be a common characteristic of PCOS, but the cause of this disorder and its pathogenesis still remain uncertain. Previous studies had proved that dysregulation of microRNAs is related to the pathogenesis of PCOS. In this study, we investigated the effect of miR-323-3p on the human cumulus cells (CCs). We also investigated the underlying mechanisms of miR-323-3p on human granulosa-like tumor cell line (KGN) or primary human CCs by stimulating with Dihydrotestosterone (DHT). Our findings suggested that the level of miR-323-3p in human CCs of women with PCOS was down-regulated, compared with that of the control group. Moreover, the inhibition of the level of miR-323-3p could up-regulate of the steroidogenesis and promote the apoptosis in KGN cells. In addition, our data confirmed that the Insulin-like growth factor 1 (IGF-1) gene was the direct target of miR-323-3p. Furthermore, the mimic of miR-323-3p inhibited the expression of IGF-1, which down-regulated the levels of AR, AMHR II, CYP19A, EGFR, and GATA-4. In conclusion, miR-323-3p targeting IGF-1 regulates the steroidogenesis and the activity of CCs, which plays an important role in the occurrence and development of PCOS. Our results have shown that miR-323-3p is a novel and promising molecular target for the improvement of the dysfunction of CCs in PCOS. PMID- 30300683 TI - Combined use of bFGF/EGF and all-trans-retinoic acid cooperatively promotes neuronal differentiation and neurite outgrowth in neural stem cells. AB - Neural stem cells (NSCs) as sources of new neurons in brain injuries or diseases are required to not only elicit neurons for neuronal repair, but also to enhance neurite outgrowth for neuronal network reestablishment. Various trophic or chemotropic factors have been shown to cooperatively improve NSC neurogenesis. However, effects of combined treatment of all-trans-retinoic acid (RA) with GF (Basic fibroblast growth factor and epidermal growth factor, bFGF/EGF) on neurogenesis of NSCs are poorly understood. To address this question, NSCs were isolated from the forebrains of embryonic mice, and treated with GF and RA either alone or in combination for differentiation in vitro. Neurons and astrocytes differentiated from NSCs were stained for MAP2 and GFAP separately by immunofluorescence. The results indicated that GF displayed superior efficacy in promoting neuronal differentiation, and RA showed better efficacy in advancing neurite outgrowth by increasing both neurite length and number. In addition, higher differentiation efficiency of neurons to astrocytes in RA or GF, or both acted at the early stage. However, more importantly, compared with RA alone, GF and RA in combination enhanced neuronal differentiation. Moreover, the combined use of GF and RA increased the length and number of neurites compared with GF, as well as the relative expression level of Smurf1. In addition, astrocytes induced by GF, RA, or both exhibited a radial glia-like morphology with long processes differing from serum effects, which might in part attribute to the total numbers of neurons. These findings for the first time unveil the roles of combined use of GF and RA on the neurogenesis of NSCs, suggesting that the use of this combination could be a comprehensive strategy for the functional repair of the nervous system through promoting neuronal differentiation, and advancing neurite outgrowth. PMID- 30300684 TI - Resting Heart Rate and Chronotropic Response to Exercise: Prognostic Implications in Heart Failure Across the Left Ventricular Ejection Fraction Spectrum. AB - BACKGROUND: We studied the relationship between resting heart rate (HR), chronotropic response to exercise, and clinical outcomes in patients with heart failure (HF) across the spectrum of left ventricle ejection fraction (LVEF). METHODS AND RESULTS: Resting HR and chronotropic index (CIx) were assessed in 718 patients with HF (53 +/- 14 years of age, 66% male) referred for exercise testing. Associations with the composite outcome of left ventricular assist device implantation, transplantation, or death (151 events, 4.4 [range 3.0-5.8] years of follow-up) were assessed with the use of Cox models adjusted for age, sex, HF etiology, diabetes, LVEF, beta-blocker use, device therapy, estimated glomerular filtration rate, and peak oxygen uptake. Resting HR was 73 +/- 15 beats/min, CIx was 0.60 +/- 0.26, LVEF was 34% +/- 15%, and 39% had an LVEF >=40%. Resting HR correlated poorly with CIx (r = 0.08; P = .04) and did not predict (P = .84) chronotropic incompetence (CIx <0.60). Both higher resting HR (per 5 beats/min increase: adjusted hazard ratio [HR] -1.05, 95% confidence interval [CI] 1.00-1.11) and CIx (per SD change: adjusted HR -0.77, 95% CI 0.62 0.94) were independent prognostic markers. No heterogeneity of effect was noted based on LVEF (P >.05). CONCLUSION: Higher resting HR and lower CIx are both associated with more severe HF, but correlated poorly with each other. They provide independent and additive prognostic information in HF across the LVEF spectrum. PMID- 30300685 TI - The Crossroads of Frailty and Heart Failure: What More Can We Learn? PMID- 30300686 TI - Genetic hypercalcemia. AB - A genetic disorder should be suspected in patients with hypercalcemia, notably those who are young; have family members with hypercalcemia; or have had a tumor of the endocrine pancreas, thyroid, pituitary, adrenal gland, or jaw bone. All forms of hypercalcemia should be interpreted according to the serum level of parathyroid hormone (PTH). Genetic forms are thus classified as related or unrelated to a parathyroid gland disorder. When the PTH level is elevated or is not depressed despite the hypercalcemia, findings that suggest family history of hypercalcemia due to a genetic cause include syndromic manifestations in the patient or family members, parathyroid cancer (either suspected before surgery or confirmed during parathyroidectomy), multiple or recurrent parathyroid tumors, a family history of primary hyperparathyroidism, and the onset of primary hyperthyroidism before 50 years of age. In patients with moderate hypercalcemia, a normal PTH level, and relative hypocalciuria, the first hypothesis is a mutation in the calcium-sensing receptor gene, which is often difficult to distinguish from primary hyperparathyroidism, particularly when there is no known family history of hyperparathyroidism, as is often the case. A low PTH level suggests non-parathyroid hypercalcemia due to a genetic defect in patients with no evidence of other conditions associated with hypercalcemia and low PTH levels and in those whose calcitriol levels are elevated or normal (instead of depressed as expected when PTH is elevated). Patients with hypercalciuria but no evidence of conditions such as granulomatous diseases should be evaluated for increased vitamin D sensitivity due to a CYP 4A1 mutation. Other very rare causes include hypophosphatasia due to ALPL mutations, which is characterized by a low alkaline phosphatase level; and renal phosphate wasting due to an NPT2A mutation, in which serum phosphate levels are low. A thorough analysis of the clinical and laboratory data can point toward a genetic disorder in patients with hypercalcemia. The diagnosis is then confirmed by obtaining genetic tests tailored to the clinical and laboratory test abnormalities. The current development of diagnostic genetic testing is shedding new light on the phenotypes, thereby improving their management.

AB - OBJECTIVES: The aim of this study was to provide a comprehensive overview of the clinically relevant anatomical and histological aspects of the development of the human pancreas, with emphasis on the vascularization of the gland. METHODS: A comprehensive search on the relevant aspects of pancreatic biology was performed through the main electronic databases up to August 2017. Data from all relevant articles was gathered, analyzed and included in this narrative review. RESULTS: This review outlines the main topics on embryology, anatomy, histology, and molecular biology of the microcirculation of the human pancreas. The first part describes in detail the development of the pancreas synthesizing anatomical knowledge with findings of novel molecular studies. The second and third parts give information on the organization of arterial and venous pancreatic circulation. The final part summarizes the most important findings concerning pancreatic microcirculation. All parts taken together create a comprehensive and up-to-date description of the development and organization of the blood supply to the human pancreas. CONCLUSIONS: Detailed knowledge on the physiological development of the pancreas and anatomy of its blood supply play a key role in understanding the pathophysiology of various pancreatic disorders and is crucial for developing novel therapies for pancreatic disorders. PMID- 30300688 TI - Trial integration of combined ultrasound and laparoscopy tuition in an undergraduate anatomy class with volunteer participation - A pilot study. AB - Anatomy is a cornerstone of medical undergraduate curricula. Due to increasing changes in various medical fields, a lot of new subjects were introduced in undergraduate curricula, while the teaching areas of basic sciences, i.e. anatomy, were reduced. The introduction of advanced diagnostic and therapeutic devices, i.e. ultrasound and laparoscopy, with outstanding imaging quality will be increasingly introduced in basic sciences. In our project, we examined the effect integrating ultrasound and laparoscopy in an anatomy undergraduate course to illustrate the female pelvis. Anatomy students that completed their practicum and cadaver dissection course were enrolled in our project. They received a theoretical introduction followed by a practical course of ultrasound or laparoscopy in the department of obstetrics and gynaecology. Following the course the students had to answer two questionnaires that evaluated their satisfaction, subjective knowledge-gain, problems and content of the course. At the end, a closing briefing was done to discuss the clinical skills and the course. The answers of the questionnaire were summed up in a Likert scale. 25 students were enrolled in the project. 52% attended laparoscopy operations, while 48% attended ultrasound examinations. After analysing the questionnaires using Likert scales (1=strongly agree, 5=strongly disagree) a general satisfaction of 1.5, a subjective knowledge gain of 2.4 and a thrive to extend these clinical skill programs in gynaecology and other specialities in basic science of 1.5 and 1.2, respectively, was reported. There were no statistically significant differences in the Likert scores between both groups (p>0.05). The introduction of ultrasound and laparoscopy in undergraduate basic science teaching programs is a promising method and should be further evaluated, standardized and expanded. PMID- 30300690 TI - Comparative spermatozoal ultrastructure and molecular analysis in dromiid crabs and their phylogenetic implications for Dromiidae and Podotremata (Decapoda: Brachyura). AB - We described the spermatozoal ultrastructure and conducted a molecular analysis of Dromiidae Hypoconcha parasitica, Hypoconcha arcuata, Moreiradromia antillensis and Dromia erythropus. To elucidate the relationship between the different species of this brachyuran group, we also compared the spermatozoal morphologies and phylogenetic positioning among species of Dromiidae, Dromioidea and Podotremata. Specimens were collected from the northern coast of Sao Paulo, Brazil and were fixed and processed followed by transmission electron microscopy and molecular analysis routines. The Dromiidae spermatozoa studied are characterized by a discoidal acrosome, with three or four concentric zones, which are centrally separated by a bilaterally capitate perforatorial chamber, with a "mushroom"-shaped apex in the Hypoconchinae and a "T-shape" in Dromiinae. Above the perforatorial chamber, there is an apical protuberance, continuous with the subopercular region and the operculum, which forms a low, centrally perforated dome. Under differential interference contrast microscopy, the spermatozoa show 3 to 4 radial arms. The spermatozoal characters in Hypoconchinae and Dromiinae do not separate these subfamilies from the Dromiidae and Dromioidea. Ultrastructural differentiation was only found between representative Dromioidea and other Podotremata. Thus, the spermiotaxonomy of these Hypoconcha, Moreiradromia and Dromia species corroborated previous morphological and molecular studies, supporting the monophyly of Dromiidae and Dynomenidae in relation to Homolidae and Latreilliidae. PMID- 30300689 TI - The Needs and Benefits of Continuous Model Updates on the Accuracy of RT-induced Toxicity Prediction Models within a Learning Health System. AB - BACKGROUND: and Purpose: Clinical data collection and development of outcome prediction models by machine learning can form the foundation for a learning health system offering precision radiotherapy. However, changes in clinical practice over time can affect the measures and outcomes of patients and hence the collected data. We hypothesize that regular prediction model updates along with continuous prospective data collection is important to prevent the degradation of a model's predication accuracy. MATERIAL AND METHODS: Clinical and dosimetric data from head and neck patients receiving intensity-modulated radiation therapy from 2008 to 2015 were prospectively collected as a routine clinical workflow and anonymized for the analysis. Prediction models for grade>=2 xerostomia at 3 to 6 month follow-up were developed by bivariate logistic regression using DVH of parotid and submandibular glands. A baseline prediction model was developed with training dataset from 2008 to 2009. The selected predictor variables and coefficients were updated by four different model updating methods: (A) The prediction model was updated by using only recent two-year data and applied to patients in the following test year. (B) The model was updated by increasing the training dataset yearly. (C) The model was updated by increasing the training dataset on condition that the area under the curve (AUC) of the recent test year was less than 0.6. (D) The model was not updated. The AUC of the test dataset was compared among the four model updating methods. RESULTS: Dose to parotid and submandibular glands and grade of xerostomia showed decreasing trends over the years (2008-2015, 297 patients, p<0.001). The AUC of predicting grade>=2 xerostomia for the initial training dataset (2008-2009, 41 patients) was 0.6196. The AUC for the test dataset (2010-2015, 256 patients) decreased to 0.5284 when the initial model was not updated (D). However, the AUC was significantly improved by model updates (A: 0.6164, B: 0.6084, p<0.05). When the model was conditionally updated, the AUC was 0.6072 (C). CONCLUSIONS: Our preliminary results demonstrate that updating prediction models with prospective data collection is effective for maintaining the performance of xerostomia prediction. This suggests that a machine learning framework can handle the dynamic changes in a radiation oncology clinical practice and may be an important component for the construction of a learning health system.

PMID- 30300691 TI - Deformable liposomes for skin therapy with human epidermal growth factor: The effect of liposomal surface charge. AB - The topical administration of exogenous human epidermal growth factor (hEGF) is a promising approach for improved chronic wound therapy. To develop therapeutically superior hEGF formulation, we prepared hEGF-containing neutral (NDLs), cationic (CDLs) and anionic (ADLs) deformable liposomes (DLs), respectively, since it is expected that the liposomal surface charge can affect both the liposomal physicochemical properties, their skin penetration potential and therapeutic efficacy of liposome-associated drug. All prepared liposomes were of similar size (300-350 nm) with high hEGF load (~80% entrapment efficacy). Among the studied DLs, ADLs were found to be most promising for sustained release of hEGF, as assessed in vitro using the polyamide membrane. Ex vivo studies revealed that all DLs were excellent systems for skin therapy with hEGF and no penetration of hEGF through the full thickness human skin was detected. ADLs provided a depot exhibiting the highest hEGF retention onto the human skin surface. ADLs also revealed enhanced mitogenic activities in human fibroblasts compared to both NDLs and CDLs after 48 hrs treatment. Moreover, hEGF-containing ADLs significantly enhanced mitogenic activity in fibroblast as compared to activity of hEGF solution (positive control). Similar trends were observed in human keratinocytes after 24 hrs of treatment. We proved that the liposomal surface charge affects the therapeutic potential of hEGF-containing liposomes. hEGF-containing ADLs can be a promising nanosystem-based formulation for localized therapy of chronic wounds. PMID- 30300694 TI - Comparison of in vitro antibacterial activity of streptomycin-diclofenac loaded composite biomaterial dressings with commercial silver based antimicrobial wound dressings. AB - Infected chronic wounds heal slowly, exhibiting prolonged inflammation, biofilm formation, bacterial resistance, high exudate and ineffectiveness of systemic antimicrobials. Composite dressings (films and wafers) comprising polyox/carrageenan (POL-CAR) and polyox/sodium alginate (POL-SA), loaded with diclofenac (DLF) and streptomycin (STP) were formulated and tested for antibacterial activity against 2 * 105 CFU/mL of Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus representing infected chronic wounds and compared with marketed silver dressings. Minimum inhibitory concentration (MIC) showed higher values for DLF than STP due to non-conventional antibacterial activity of DLF. The DLF and STP loaded dressings were highly effective against E. coli, P. aeruginosa and S. aureus. POL-SA dressings were more effective against the three types of bacteria compared to POL-CAR formulations, while the DLF and STP loaded dressings showed greater antibacterial activity than the silver-based dressings. The films, showed greater antibacterial efficacy than both wafers and silver dressings. STP and DLF can act synergistically not only to kill the bacteria but also prevent their resistance and biofilm formation compared to silver dressings, while reducing chronic inflammation associated with infection. PMID- 30300695 TI - Fucosterol exerts protection against amyloid beta-induced neurotoxicity, reduces intracellular levels of amyloid beta and enhances the mRNA expression of neuroglobin in amyloid beta-induced SH-SY5Y cells. AB - Alzheimer's disease (AD) is a neurodegenerative disease that leads to progressive loss of neurons which often results in deterioration of memory and cognitive function. The development of AD is highly associated with the formation of senile plaques and neurofibrillary tangles. Amyloid beta (Abeta) induces neurotoxicity and contributes to the development of AD. Recent evidences also highlighted the importance of neuroglobin (Ngb) in ameliorating AD. This study assessed the ability of fucosterol, a phytosterol found in brown alga, in protecting SH-SY5Y cells against Abeta-induced neurotoxicity. Its effects on the mRNA levels of APP and Ngb as well as the intracellular Abeta levels were also determined in Abeta induced SH-SY5Y cells. SH-SY5Y cells were exposed to fucosterol prior to Abeta treatment. The effect on apoptosis was determined using Annexin V FITC staining and mRNA expression was studied using RT-PCR. Flow cytometry confirmed the protective effects of fucosterol on SH-SY5Y cells against Abeta-induced apoptosis. Pretreatment with fucosterol increased the Ngb mRNA levels but reduced the levels of APP mRNA and intracellular Abeta in Abeta-induced SH-SY5Y cells. These observations demonstrated the protective properties of fucosterol against Abeta-induced neurotoxicity in neuronal cells. PMID- 30300696 TI - Snakegourd root/Astragalus polysaccharide hydrogel preparation and application in 3D printing. AB - Hydrogels have good water retention, biocompatibility and biodegradability, so they are well used in the medical industry. Here, we have active polysaccharide exacted from Chinese traditional medicine and carboxymethyl chitosan cross-linked to form hydrogel and characterized them by Scanning electron microscopy, FTIR analysis, swelling, degradation, release and cytotoxicity tests. We printed the composite hydrogel into patches with three different shapes by Hot-Melt extruded 3D printer and studied the effects of different shapes on the release of drug. The results show, under acidic or alkaline conditions, the BSA cumulative release rate of the three hydrogel patches with different shape range from 49% to 89%. Therefore, there is a significant difference in the release between circular, cube and rectangular shape. Through the study, we found that the hydrogels we prepared have excellent potential for future applications in drug delivery system. PMID- 30300697 TI - Investigating the effect of chitosan on hydrophilicity and bioactivity of conductive electrospun composite scaffold for neural tissue engineering. AB - In this paper, nanofibers containing poly(epsilon-caprolactone) (PCL), chitosan and polypyrrole (PPy) were fabricated using electrospinning to combine advantages of electrospun nanofibers topography with versatile advantages of chitosan and PPy. Various compositions of the PCL/chitosan/PPy polymeric scaffolds were fabricated by electrospinning and were analyzed for their surface topography, hydrophilicity and bioactivity. The results illustrated that chitosan in the scaffold imposed significant advancement in the hydrophilicity of the scaffold as confirmed by a decrease in contact angle up to 66% (123 +/- 2.3 for PCL to 41.37 +/- 3.51 for PCL/chitosan). The average diameter of the fibers was within the range of 30-180 nm, which influenced by the concentration of the chitosan as the increase up to 30% in chitosan content decreased fiber diameter from 124 nm to 36 nm. In-vitro studies using PC12 cells revealed that the PCL/chitosan/PPy nanofibrous scaffold supports cell attachment, spreading and revealed significant increase in proliferation up to 356% in comparison to Pure PCL and neurite extension of PC12. The results indicated the PCL/chitosan/PPy nanofibrous scaffolds support the adhesion, spreading and proliferation of the PC12 cells. Therefore, this scaffold could serve as promising neural tissue substitutes. PMID- 30300698 TI - Osteogenic effectiveness of photo-immobilized bone morphogenetic protein-2 using different azidophenyl-natural polymer carriers in rat calvarial defect model. AB - The osteogenetic potential of photo-immobilized azdiophenyl (Az)-natural polymers as a carrier of bone morphogenetic protein-2 (BMP-2) was assessed in 56 rats randomized to four groups. The control group comprised implanted collagen sheet with BMP-2. In the three experimental groups, the implant comprised collagen sheet with photo-immobilized BMP-2 on Az-gelatin (Az-Gel), Az-O-carboxymethyl chitosan (Az-OMC), or Az-O-carboxymethyl low molecular chitosan (Az-LMC). Micro computed tomography analysis revealed more regenerated bone in Az-Gel at 8weeks. Immunohistochemical analysis at 4weeks revealed that the positively expressed cellular ratio in RUNX2-stained cells was significantly higher in Az-Gel and Az OMC groups. At 8weeks, only the Az-Gel group showed higher positively expressed cellular ratio compared with the control group. These results demonstrate the superior osteogenetic potential of photo-immobilized BMP-2 using Az-Gel carrier in a rat calvarial defect model compared with control group. Photo-immobilization of BMP-2 using Az-gelatin could be a more effective carrier system of BMP-2 than a chitosan-based carrier system. PMID- 30300699 TI - Advantages of short repetition time resting-state functional MRI enabled by simultaneous multi-slice imaging. AB - BACKGROUND: Recent advancements in simultaneous multi-slice (SMS) imaging techniques have enabled whole-brain resting-state fMRI (rs-fMRI) scanning at sub second temporal resolution, providing spectral ranges much wider than the typically used range of 0.01-0.1 Hz. However, the advantages of this accelerated acquisition for rs-fMRI have not been evaluated. NEW METHOD: In this study, we used SMS Echo Planar Imaging (EPI) to probe whole-brain functional connectivity with a short repetition time (TR = 350 ms) and compared it with standard EPI with a longer TR of 2000 ms. We determined the effect of scan length and investigated the temporal filtration strategies that optimize results based on metrics of signal-noise separation and test-retest reliability using both seed-based and independent component analysis (ICA). RESULTS: We found that use of either the entire frequency range of 0.01-1.4 Hz or the entire frequency range with the exclusion of typical cardiac and respiratory frequency values tended to provide the best functional connectivity maps. COMPARISON WITH EXISTING METHODS: We found that the SMS-acquired rs-fMRI scans had improved the signal-noise separation, while preserving the same level of test-retest reliability compared to conventional EPI, and enabled the detection of reliable functional connectivity networks with scan times as short as 3 min. CONCLUSIONS: Our findings suggest that whole-brain rs-fMRI studies may benefit from the increased temporal resolution enabled by the SMS-EPI acquisition, leading to drastic scan time reductions, which in turn should enable the more widespread use of rs-fMRI in clinical research protocols. PMID- 30300700 TI - Simulating human sleep spindle MEG and EEG from ion channel and circuit level dynamics. AB - BACKGROUND: Although they form a unitary phenomenon, the relationship between extracranial M/EEG and transmembrane ion flows is understood only as a general principle rather than as a well-articulated and quantified causal chain. METHOD: We present an integrated multiscale model, consisting of a neural simulation of thalamus and cortex during stage N2 sleep and a biophysical model projecting cortical current densities to M/EEG fields. Sleep spindles were generated through the interactions of local and distant network connections and intrinsic currents within thalamocortical circuits. 32,652 cortical neurons were mapped onto the cortical surface reconstructed from subjects' MRI, interconnected based on geodesic distances, and scaled-up to current dipole densities based on laminar recordings in humans. MRIs were used to generate a quasi-static electromagnetic model enabling simulated cortical activity to be projected to the M/EEG sensors. RESULTS: The simulated M/EEG spindles were similar in amplitude and topography to empirical examples in the same subjects. Simulated spindles with more core dominant activity were more MEG weighted. COMPARISON WITH EXISTING METHODS: Previous models lacked either spindle-generating thalamic neural dynamics or whole head biophysical modeling; the framework presented here is the first to simultaneously capture these disparate scales. CONCLUSIONS: This multiscale model provides a platform for the principled quantitative integration of existing information relevant to the generation of sleep spindles, and allows the implications of future findings to be explored. It provides a proof of principle for a methodological framework allowing large-scale integrative brain oscillations to be understood in terms of their underlying channels and synapses. PMID- 30300701 TI - Coding of "Home Cage" by PFC Neurons. AB - Contexts play critical roles in many important aspects of an animal's routine functions, such as the interpretation of incoming signals and retrieved memories. The roles played by prefrontal cortex (PFC) neurons in the coding of contexts have been largely studied in relation to aversive stimuli (such as foot shock in conditioned fear). Whether PFC neurons may code contexts that mice encounter in everyday life, such as their home cage, is poorly understood. Here, we report the identification of a subpopulation of ventral medial PFC (vmPFC) neurons which change their spike rates when mice enter or leave their home cages. Both increase (ON units) and decrease (OFF units) in spike rate were observed, with about 2/3 of neurons showing decrease and 1/3 showing increase. These changes were evident whenever transitions occur from home cage to a different environment regardless of the novelty of the environments. In addition, changes in firing rate were not affected when mice entering a context where fear conditioning had taken place after contextual or auditory/cued fear conditioning. Furthermore, we found that the differential spike rates of ON and OFF units appear to allow mice to recognize that they are inside their home cages. Together, vmPFC neural spiking appears to enable the encoding of "home cage". PMID- 30300702 TI - Cross-modal Restoration of Juvenile-like Ocular Dominance Plasticity after Increasing GABAergic Inhibition. AB - In juvenile and young adult mice monocular deprivation (MD) shifts the ocular dominance (OD) of binocular neurons in the primary visual cortex (V1) away from the deprived eye. However, OD plasticity is completely absent in mice older than 110 days, but can be reactivated by treatments which decrease GABA levels in V1. Typically, these OD shifts can be prevented by increasing GABAergic transmission with diazepam. We could recently demonstrate that both bilateral whisker and auditory deprivation (WD, AD), can also restore OD plasticity in mice older than 110 days, since MD for 7 days in WD mice caused a potentiation of V1 input through the ipsilateral (open) eye, the characteristic feature of OD plasticity of "young adult" mice. Here we examined whether WD for 7 days also decreases GABA levels. For this, we performed post mortem HPLC analysis of V1 tissue. Indeed, we found that WD significantly decreased GABA levels in V1. Surprisingly, enhancing GABAergic inhibition by diazepam did not abolish OD shifts in WD mice, as revealed by repeated intrinsic signal imaging. On the contrary, this treatment led to a depression of V1 input through the previously closed contralateral eye, the characteristic signature of OD plasticity in juvenile mice during the critical period. Interestingly, the same result was obtained after AD. Taken together, these results suggest that cross-modally restored OD plasticity does not only depend on reduction of GABA levels in V1, but also requires other, so far unknown mechanisms. PMID- 30300703 TI - Inhibiting Succinate Dehydrogenase by Dimethyl Malonate Alleviates Brain Damage in a Rat Model of Cardiac Arrest. AB - Brain damage is a leading cause of death in patients with cardiac arrest (CA). The accumulation of succinate during ischemia by succinate dehydrogenase (SDH) is an important mechanism of ischemia-reperfusion injury. It was unclear whether inhibiting the oxidation of accumulated succinate could also mitigate brain damage after CA. In this study, rats were subjected to a 6 min of CA, and cardiopulmonary resuscitation (CPR) was performed with administration of normal saline or dimethyl malonate (DMM, a competitive inhibitor of SDH). After the return of spontaneous circulation, neurological function of the rats was assessed by a tape removal test for 3 days. The rats were then sacrificed, and their brains were used to assess neuronal apoptosis by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Hippocampal tissues were used for Western blotting analysis and biochemical detection. In addition, hippocampal mitochondria during CA and CPR were isolated. The relative mitochondrial membrane potential (MMP) and cytochrome C in the cytosol were detected. Our results show that DMM promoted ROSC and neurological performance in rats after CA. The TUNEL assay showed that DMM reduced neuronal apoptosis. Western blotting analysis showed that DMM inhibited the activation of caspase-3 and enhanced the expression of HIF-1alpha. Moreover, DMM inhibited excessive hyperpolarization of MMP after CPR, and prevented the release of cytochrome C. Therefore, inhibiting SDH by DMM alleviated brain damage after CA, and the main mechanisms included inhibiting the excessive hyperpolarization of MMP, reducing the generation of mtROS and stabilizing the structure of HIF-1alpha. PMID- 30300704 TI - Local Injection of Endothelin-1 in the Early Neonatal Rat Brain Models Ischemic Damage Associated with Motor Impairment and Diffuse Loss in Brain Volume. AB - Cerebral palsy is an irreversible movement disorder resulting from cerebral damage sustained during prenatal or neonatal brain development. As survival outcomes for preterm injury improve, there is increasing need to model ischemic injury at earlier neonatal time-points to better understand the subsequent pathological consequences. Here we demonstrate a novel neonatal ischemic model using focal administration of the potent vasoconstrictor peptide, endothelin-1 (ET-1), in newborn rats. The functional and histopathological outcomes compare favourably to those reported following the widely used hypoxic ischemia (HI) model. These include a robust motor deficit sustained into adulthood and recapitulation of hallmark features of preterm human brain injury, including atrophy of subcortical white matter and periventricular fiber bundles. Compared to procedures involving carotid artery manipulation and periods of hypoxia, the ET-1 ischemia model represents a rapid and technically simplified model more amenable to larger cohorts and with the potential to direct the locus of ischemic damage to specific brain areas. PMID- 30300705 TI - The Effects of Waveform and Current Direction on the Efficacy and Test-Retest Reliability of Transcranial Magnetic Stimulation. AB - The pulse waveform and current direction of transcranial magnetic stimulation (TMS) influence its interactions with the neural substrate; however, their role in the efficacy and reliability of single- and paired-pulse TMS measures is not fully understood. We investigated how pulse waveform and current direction affect the efficacy and test-retest reliability of navigated, single- and paired-pulse TMS measures. 23 healthy adults (aged 18-35 years) completed two identical TMS sessions, assessing resting motor threshold (RMT), motor-evoked potentials (MEPs), cortical silent period (cSP), short- and long-interval intra-cortical inhibition (SICI and LICI), and intracortical facilitation (ICF) using either monophasic posterior-anterior (monoPA; n = 9), monophasic anterior-posterior (monoAP; n = 7), or biphasic (biAP-PA; n = 7) pulses. Averages of each TMS measure were compared across the three groups and intraclass correlation coefficients were calculated to assess test-retest reliability. RMT was the lowest and cSP was the longest with biAP-PA pulses, whereas MEP latency was the shortest with monoPA pulses. SICI and LICI had the largest effect with monoPA pulses, whereas only monoAP and biAP-PA pulses resulted in significant ICF. MEP amplitude was more reliable with either monoPA or monoAP than with biAP-PA pulses. LICI was the most reliable with monoAP pulses, whereas ICF was the most reliable with biAP-PA pulses. Waveform/current direction influenced RMT, MEP latency, cSP, SICI, LICI, and ICF, as well as the reliability of MEP amplitude, LICI, and ICF. These results show the importance of considering TMS pulse parameters for optimizing the efficacy and reliability of TMS neurophysiologic measures. PMID- 30300706 TI - Polysorbate degradation in biotherapeutic formulations: Identification and discussion of current root causes. AB - Biotherapeutic protein formulations are often high concentration liquid protein solutions, which are required to be stable under pharmaceutically relevant storage conditions and presence of external stress. Non-ionic detergents like polysorbate have been the most commonly used detergent to maintain formulation stability. Recently, particle formation in polysorbate containing biotherapeutic formulations has arisen as a major quality concern and potential patient risk factor. In this review, we provide a general overview into (i) degradation of polysorbates, (ii) polysorbate analytics, (iii) particle formation induced by polysorbate degradation and root causes thereof, (iv) particle composition and (v) various influencing factors that might lead to particle formation. Consequently, we explore the role of polysorbate degradation in particle formation. Additionally, various degradation pathways and the current discussed root causes are reviewed. PMID- 30300707 TI - Antitumor effect of a liposome-encapsulated beta1,4-galactosyltransferase inhibitor. AB - Galactosyltransferases are a family of enzymes responsible for the synthesis of glycan chains which are involved in cell proliferation, adhesion and apoptosis. A recently synthesized galactosyltransferase inhibitor, 2-naphthyl 2-butanamido-2 deoxy-1-thio-beta-D-glucopyranoside (612), has been found to selectively inhibit beta1,4-galactosyltransferase over beta1,3-galactosyltransferase and, therefore, has potential to suppress the synthesis of cancer associated epitopes. However, the application of this inhibitory activity in biological systems remains unknown. In this study, 612 was introduced into a cationic liposome (LP) delivery system, and the anti-proliferative effects of both free and the LP-incorporated 612 (612-LP) were investigated in A549 lung cancer cells, which actively express anionic sialic acid moieties on the surfaces of cells. The anti-proliferative effects were evaluated via MTT assays. The results revealed that free 612 and empty LP impose neither anti-proliferative nor apoptotic effects on cancer cells at low doses, whereas the 612-LP system inhibited cancer cell growth at a concentration as low as 0.1 MUg/mL after 3 days of incubation, suggesting that this formulation enabled efficient delivery of 612 into cells and promoted the anti-proliferative activity of 612 against cancer cells. Therefore, this highly specific inhibitor 612 has the potential for development as an effective anti cancer agent and merits further investigation. PMID- 30300708 TI - Polysaccharide-based film loaded with vitamin C and propolis: A promising device to accelerate diabetic wound healing. AB - Wound healing can be a painful and time-consuming process in patients with diabetes mellitus. In light of this, the use of wound healing devices could help to accelerate this process. Here, cellulose-based films loaded with vitamin C (VitC) and/or propolis (Prop), two natural compounds with attractive properties were engineered. The starting materials and the cellulose-based films were characterized in detail. As assessed, vitamin C can be released from the Cel PVA/VitC and Cel-PVA/VitC/Prop films in a controlled manner. In vitro antibacterial activity studies showed a reduction of bacteria counts (Escherichia coli and Staphylococcus aureus) after Cel-PVA/VitC, Cel-PVA/Prop, and Cel PVA/VitC/Prop treatments. Moreover, we examined the antibacterial and wound healing properties of the cellulose-based films in a streptozotocin (STZ)-induced diabetic animal model. Diabetic mice exhibited impaired wound healing while the Cel-PVA/VitC/Prop treatment increased the wound closure. A marked reduction in bacterial counts present in the wound environment of diabetic mice was observed after Cel-PVA/VitC, Cel-PVA/Prop and Cel-PVA/VitC/Prop treatment. Histological analysis demonstrated that the non-treated diabetic mice group did not exhibit adequate wound healing while the treated group with Cel-PVA/VitC and Cel PVA/VitC/Prop films presented good cicatricial response. Furthermore, these novel eco-friendly films may represent a new therapeutic approach to accelerate diabetic wound healing. PMID- 30300709 TI - Analysis of pin milling of pharmaceutical materials. AB - Milling is an important process for tailoring the particle size distribution for enhanced dissolution, content uniformity, tableting, etc., specially for active pharmaceutical ingredients and excipient in pharmaceutical industries. Milling performance of particulate solids depends on the equipment operating conditions (geometry, process conditions and input energy etc.) as well as material properties (particle size, shape, and mechanical properties, such as Young's modulus, hardness and fracture toughness). In this work, a newly developed approach to assess the breakability of pharmaceutical materials using an aerodynamic dispersion method has been combined with the Discrete Element Method (DEM) to simulate the dynamic behaviour of a number of pharmaceutical materials in a pin mill. A sensitivity analysis is carried out addressing the effect of the milling conditions (rotational speed of the mill and feed particle flow rate) and feed properties on the milled products in terms of the shift in the specific surface area of the milled particles. The outcome of the work is used as a method to predict the breakage of the particles for the milling conditions where chipping takes place. PMID- 30300710 TI - Two siblings with a novel nonsense variant provide further delineation of the spectrum of recessive KLHL7 diseases. AB - Mutations in Kelch-like family member 7 (KLHL7) have recently been described as a cause of a constellation of clinical findings with descriptions of both a Crisponi syndrome (CS)/cold-induced sweating syndrome type 1 (CISS1)-like, as well as a Bohring-Opitz syndrome (BOS)-like presentation. Here we report two siblings of Guatelmalan descent with a novel homozygous nonsense mutation (p.Arg326*) in KLHL7. These children have multiple dysmorphic features and developmental delay. Interestingly, their clinical traits inconsistently overlap both the CS/CISS1-like and BOS-like phenotypes, and the siblings also have subtle differences from each other, suggesting that clinicians need to be aware of the degree of variability in the presentations of these patients. Still, there is enough in common between patients with recessive KLHL7 mutations to define a novel multisystem disease that features various neurodevelopmental, musculoskeletal, dysmorphic, and other unique components. This report adds to the clinical features and disease-associated variants of the newly-recognized spectrum of KLHL7 mutations, and offers a new description, PERCHING, for the resulting syndrome.

AB - Cartilaginous extracellular matrix (ECM) materials derived from decellularized native articular cartilage are widely used in cartilage regeneration. However, it is difficult for endogenous cells to migrate into ECM derived from native cartilage owing to its nonporous structure and dense nature. Moreover, current decellularization approaches frequently lead to architectural breakdown and potential loss of surface composition of ECM. To solve this problem, we aimed to establish a novel biological ECM scaffold from chondrocyte sheets for cartilage regeneration. We cultured chondrocytes harvested from the auricular cartilage of 4-week-old New Zealand rabbits and enabled them to form cell sheets. These sheets were decellularized using sodium dodecyl sulfate (SDS) with three different concentrations, namely, 1%, 5%, and 10%, followed by 1% Triton X-100 and deoxyribonuclease enzyme solution. In vitro microstructural examination and mechanical tests demonstrated that 1% SDS not only removed chondrocytes completely but also maintained the native architecture and composition of ECM, thus avoiding the use of high-concentration SDS. Application of decellularized chondrocyte sheets for osteochondral defects in rabbits resulted in substantial host remodeling and variant regeneration of osteochondral tissues. One percent SDS-treated decellularized chondrocyte sheets contributed to the superior reconstruction of osteochondral defects as compared with 5% and 10% SDS groups, which includes vascularized subchondral bone, articular cartilage with adequate thickness, and integration with host tissues. Furthermore, ECM from 1% SDS significantly increased the migrating potential of bone marrow mesenchymal stem cells (BMSCs) in vitro. RT-PCR and western blot also revealed that ECM increased the expression of SOX-9 in BMSCs, whereas it decreased COL-X expression. In conclusion, our results suggested that the chondrocyte sheets decellularized with 1% SDS preserved the integrity and bioactivity, which favored cell recruitment and enabled osteochondral regeneration in the knee joints of rabbits, thus offering a promising approach for articular cartilage reconstruction without cell transplantation. STATEMENT OF SIGNIFICANCE: Although biological extracellular matrix (ECM) derived from decellularized native cartilage has been widely used in cartilage regeneration, it is difficult for endogenous cells to migrate into ECM owing to its dense nature. Moreover, current decellularization approaches lead to architectural breakdown of ECM. This study established a novel biological ECM from decellularized chondrocyte sheets for cartilage regeneration. Our results suggested that cartilaginous ECM favored cell recruitment and enabled osteochondral regeneration in rabbits, thus offering a promising approach for articular cartilage reconstruction without cell transplantation. SDS 1% adequately decellularized the chondrocytes in cell sheets, whereas it maintained the native architecture and composition of ECM, thereby avoiding the use of high concentration SDS and providing a new way to acquire cartilaginous ECM. PMID- 30300712 TI - Ageing, the autonomic nervous system and arrhythmia: From brain to heart. AB - An ageing myocardium possesses significant electrophysiological alterations that predisposes the elderly patient to arrhythmic risk. Whilst these alterations are intrinsic to the cardiac myocytes, they are modulated by the cardiac autonomic nervous system (ANS) and consequently, ageing of the cardiac ANS is fundamental to the development of arrhythmias. A systems-based approach that incorporates the influence of the cardiac ANS could lead to better mechanistic understanding of how arrhythmogenic triggers and substrates interact spatially and temporally to produce sustained arrhythmia and why its incidence increases with age. Despite the existence of physiological oscillations of ANS activity on the heart, pathological oscillations can lead to defective activation and recovery properties of the myocardium. Such changes can be attributable to the decrease in functionality and structural alterations to ANS specific receptors in the myocardium with age. These altered ANS adaptive responses can occur either as a normal ageing process or accelerated in the presence of specific cardiac pathologies, such as genetic mutations or neurodegenerative conditions. Targeted intervention that seek to manipulate the ageing ANS influence on the myocardium may prove to be an efficacious approach for the management of arrhythmia in the ageing population. PMID- 30300714 TI - Role of 18F-fluoro-ethyl-tyrosine Positron Emission Tomography in Investigation and Management of Suspected Gliomas. AB - BACKGROUND: This study aims to investigate the utility of 18F-fluoro-ethyl tyrosine (18F-FET) positron emission tomography in surgical decision making in suspected glioma. METHODS: A retrospective review of patients undergoing 18F-FET positron emission tomography was performed. Previously published thresholds for maximum tumor background ratios (TBRs) were used for quantitative analysis. Forty seven patients were included in the study, of whom 15 had confirmed glioma and 7 had a confirmed alternative diagnosis. RESULTS: 18F-FET showed significantly higher uptake in high-grade glioma than in nonglioma. CONCLUSIONS: Lesions with TBRmax >2.5 should be considered suspicious for glioma and biopsy considered. Threshold TBRmax >3.0 is useful for differentiating high-grade glioma from low grade glioma. This may be a particularly useful tool for directing management in eloquent areas, such as brainstem glioma. PMID- 30300715 TI - Workforce Analysis of Spine Surgeons Involved with Neurological and Orthopedic Surgery Residency Training. AB - OBJECTIVE: Spinal surgery is taught and practiced within 2 different surgical disciplines: neurological surgery and orthopedic surgery. We have provided a unified analysis of spine-focused faculty at U.S. residency programs. METHODS: A total of 278 Accreditation Council for Graduate Medical Education training programs were assessed to identify 923 full-time faculty members with a spinal surgery designation, defined by spine fellowship training or surgeon case volume >75% spine surgeries. Faculty were assessed with respect to parent discipline, years of fellowship training, academic rank, gender, and academic productivity (h index). RESULTS: The spine-teaching workforce contains 55% orthopedic surgeons and 45% neurosurgeons with wide gender asymmetry overall and at all faculty ranks. Of the female spine surgeons, those with neurosurgical training (64.44%) nearly doubled the number with orthopedic training (35.56%). Academic productivity increased with academic rank similarly for both genders and subspecialties. Orthopedic spine surgeons had a greater mean fellowship number compared with the neurological spine surgeons. Fellowship time of completion (intraresidency/infolded vs. postresidency) did not significantly affect the h indexes. Addition of fellowship conferred academic productivity benefit for orthopedic surgeons only. CONCLUSIONS: Neurological and orthopedic spine surgery showed similar patterns for the spread of faculty across academic ranks and trends in academic productivity. Marked gender disparity was seen in both neurosurgical and orthopedic surgery, with fewer female spine surgeons seen at every academic rank. Orthopedic spine surgeons had a greater mean fellowship number than did their neurosurgical counterparts, and a lack of fellowship correlated with lower academic productivity in orthopedic, but not neurological, spine surgery. PMID- 30300713 TI - Association networks in a matched case-control design - Co-occurrence patterns of preexisting chronic medical conditions in patients with major depression versus their matched controls. AB - OBJECTIVE: We present a method for comparing association networks in a matched case-control design, which provides a high-level comparison of co-occurrence patterns of features after adjusting for confounding factors. We demonstrate this approach by examining the differential distribution of chronic medical conditions in patients with major depressive disorder (MDD) compared to the distribution of these conditions in their matched controls. MATERIALS AND METHODS: Newly diagnosed MDD patients were matched to controls based on their demographic characteristics, socioeconomic status, place of residence, and healthcare service utilization in the Korean National Health Insurance Service's National Sample Cohort. Differences in the networks of chronic medical conditions in newly diagnosed MDD cases treated with antidepressants, and their matched controls, were prioritized with a permutation test accounting for the false discovery rate. Sensitivity analyses for the associations between prioritized pairs of chronic medical conditions and new MDD diagnosis were performed with regression modeling. RESULTS: By comparing the association networks of chronic medical conditions in newly diagnosed depression patients and their matched controls, five pairs of such conditions were prioritized among 105 possible pairs after controlling the false discovery rate at 5%. In sensitivity analyses using regression modeling, four out of the five prioritized pairs were statistically significant for the interaction terms. CONCLUSION: Association networks in a matched case-control design can provide a high-level comparison of comorbid features after adjusting for confounding factors, thereby supplementing traditional clinical study approaches. We demonstrate the differential co-occurrence pattern of chronic medical conditions in patients with MDD and prioritize the chronic conditions that have statistically significant interactions in regression models for depression. PMID- 30300716 TI - Micafungin is a novel anti-viral agent of chikungunya virus through multiple mechanisms. AB - The chikungunya virus (CHIKV) is a mosquito-borne virus that belongs to the genus Alphavirus, family Togaviridae. It is the cause of chikungunya fever in humans, which presents a serious global threat due to its high rate of contagion. The clinical symptoms of CHIKV include fever and persistent, severe arthritis. Micafungin has broad-spectrum fungicidal activity against Candida spp. is a promising echinocandin that was recently approved by the U.S. Food and Drug Administration (FDA) and has demonstrated activity against Candida and Aspergillus. Recent studies have demonstrated the antiviral activity of micafungin; however, the inhibitory effects against CHIKV have yet to be investigated. Our objectives in this study were to explore the antiviral effects of micafungin on CHIKV infection and to elucidate the potential molecular mechanisms of inhibition. We determined that micafungin has the ability to counter CHIKV-induced cytopathic effects. We further discovered that micafungin limits virus replication, release, cell-to-cell transmission, and also slightly affected virus stability during high doses treatment. The efficacy of micafungin was further confirmed against two clinical isolates of CHIKV and two alphaviruses: Sindbis virus (SINV) and Semliki Forest virus (SFV). Our findings suggest that micafungin has considerable potential as a novel inhibitor against the viral replication, and intracellular and extracellular transmission of CHIKV, and has a little effect on virus stability. Our findings also suggest that micafungin could have curative effects on other alphavirus infections. PMID- 30300717 TI - Elbasvir plus grazoprevir for patients with chronic hepatitis C genotype 1: A multicenter, real-world cohort study focusing on chronic kidney disease. AB - The real-world effectiveness and safety of all-oral direct-acting antivirals (DAAs) for chronic hepatitis C (HCV) infection and chronic kidney disease (CKD) have not been fully elucidated. This study assesses elbasvir (EBR) plus grazoprevir (GZR) for patients with HCV genotype 1 infection in the clinical setting, focusing on CKD stage 3-5D. This multicenter, real-world cohort study consisted of 282 Japanese patients who were treated with EBR (50 mg) plus GZR (100 mg) for a fixed 12-week duration. We evaluated the sustained viral response rate 12 weeks after the end of treatment (SVR12), longitudinal liver and renal parameters, and adverse effects according to the cirrhosis and CKD status. Of those enrolled, 89 (31.6%) were CKD stage 3-5 and 21 (7.4%) were CKD stage 5D (hemodialysis-dependent). The overall and CKD stage 3-5D SVR12 rates in the per protocol populations were 98.6% (272/276) and 98.1% (101/103). High SVR12 rates were observed in almost all groups, except for prior all-oral DAA failure with NS5A resistance-associated substitutions. There was no significant change during treatment or follow-up period in estimated glomerular filtration rate, irrespective of CKD status. In contrast, the serum complement level (C3 and C4) increased, with significance for C3. Serious adverse effects were very rare, both in the groups with normal eGFR and CKD, and discontinuation was required for only six (2.1%) patients. EBR plus GZR for HCV genotype 1 was highly effective with a low rate of adverse effects, regardless of CKD status. In addition, liver parameters and complement levels improved longitudinally. PMID- 30300718 TI - Early stages of drug crystallization from amorphous solid dispersion via fractal analysis based on chemical imaging. AB - Early stages of crystallization from amorphous solid dispersion (ASD) are typically not detected by means of standard methods like powder X-ray diffraction (XRPD). The aim of this study is therefore to evaluate if fractal analysis based on energy dispersive X-ray imaging can provide the means to identify early signs of physical instability. ASDs of the poorly water-soluble compound, felodipine (FEL) were prepared by solvent evaporation using different grades of HPMCAS, at 50 wt% drug loading. Samples were stored at accelerated conditions of 40 degrees C. Scanning electron microscopy equipped with an energy-dispersive X-ray spectroscopy (SEM-EDS) was used for elemental mapping of tablet surfaces. Comparative data were generated with a standard XRPD and with more sensitive methods for detection of early instability, i.e. laser scanning confocal microscopy (LSM) and atomic force microscopy (AFM). The SEM-EDS identified changes of drug-rich domains that were confirmed by LSM and AFM. Early changes in drug clusters were also revealed by a multifractal analysis that indicated a beginning phase separation and drug crystallization. Therefore, the presented fractal cluster analysis based on chemical imaging bears much promise as a new method to detect early signs of physical instability in ASD, which is of great relevance for pharmaceutical development. PMID- 30300719 TI - Protein-polysaccharide nanohybrids: Hybridization techniques and drug delivery applications. AB - Complex nanosystems fabricated by hybridization of different types of materials such as lipids, proteins, or polysaccharides are usually superior to simple ones in terms of features and applications. Proteins and polysaccharides hold great potential for development of nanocarriers for drug delivery purposes based on their unique biocompatibility, biodegradability, ease of functionalization, improved biodistribution and minimal toxicity profiles. Protein-polysaccharide nanohybrids have gained a lot of attention in the past few years particularly for drug delivery applications. In this review, different hybridization techniques utilized in the fabrication of such nanohybrids including electrostatic complexation, Maillard conjugation, chemical coupling and electrospinning were thoroughly reviewed. Moreover, various formulation factors affecting the characteristics of the formed nanohybrids were discussed. We also reviewed in depth the outcomes of such hybridization ranging from stability enhancement, to toxicity reduction, improved biocompatibility, and drug release modulation. We also gave an insight on their limitations and what hinders their clinical translation and market introduction. PMID- 30300720 TI - Mechanistic modelling of intestinal drug absorption - The in vivo effects of nanoparticles, hydrodynamics, and colloidal structures. AB - Particle size reduction is a traditional approach to increase the intestinal absorption of active pharmaceutical ingredients with poor intestinal solubility, by increasing the particle dissolution rate. However, an increase in the dissolution rate cannot always fully explain the effects of nanoformulations, and a method of assessing the potential benefits of a nanoformulation in vivo would hence be of great value in drug development. A novel mathematical model of a nanoformulation, including interlinked descriptions of the hydrodynamics, particle dissolution and diffusion of particles and colloidal structures (CS), was developed to predict the combined in vivo effects of these mechanisms on drug absorption. The model successfully described previously reported in vivo observations of nanoformulated aprepitant in rats, at various drug concentrations and in the presence or absence of CS. The increase in absorption rate was explained as a direct consequence of the increased drug concentration at the membrane, caused by the contributing effects of the diffusion of both nanoparticles and CS into which the drug had partitioned. Further simulations supported the conclusion that the model can be applied during drug development to provide a priori assessments of the potential benefits of nanoformulations. PMID- 30300721 TI - DNA Demethylation by DNMT3A and DNMT3B in vitro and of Methylated Episomal DNA in Transiently Transfected Cells. AB - The DNA methylation program in vertebrates is an essential part of the epigenetic regulatory cascade of development, cell differentiation, and progression of diseases including cancer. While the DNA methyltransferases (DNMTs) are responsible for the in vivo conversion of cytosine (C) to methylated cytosine (5mC), demethylation of 5mC on cellular DNA could be accomplished by the combined action of the ten-eleven translocation (TET) enzymes and DNA repair. Surprisingly, the mammalian DNMTs also possess active DNA demethylation activity in vitro in a Ca2+- and redox conditions-dependent manner, although little is known about its molecular mechanisms and occurrence in a cellular context. In this study, we have used LC-MS/MS to track down the fate of the methyl group removed from 5mC on DNA by mouse DNMT3B in vitro and found that it becomes covalently linked to the DNA methylation catalytic cysteine of the enzyme. We also show that Ca2+ homeostasis-dependent but TET1/TET2/TET3/TDG-independent demethylation of methylated episomal DNA by mouse DNMT3A or DNMT3B can occur in transfected human HEK 293 and mouse embryonic stem (ES) cells. Based on these results, we present a tentative working model of Ca2+ and redox conditions dependent active DNA demethylation by DNMTs. Our study substantiates the potential roles of the vertebrate DNMTs as double-edged swords in DNA methylation demethylation during Ca2+-dependent physiological processes. PMID- 30300722 TI - Complementary feeding may pose a risk of simultaneous exposures to aflatoxin M1 and deoxynivalenol in Indian infants and toddlers: Lessons from a mini-survey of food samples obtained from Kolkata, India. AB - A mini-survey of 29 different foods produced by 21 different Indian manufacturers was conducted for the presence of aflatoxins B1, B2, G1 and G2, aflatoxin M1 and deoxynivalenol. The products were purchased from local markets in Kolkata, India and commonly used in the complementary feeding of infants and toddlers in India. Using a previously established direct competitive enzyme-linked immunoassay for this analysis we show that 100% of the samples contained aflatoxin M1 at levels exceeding the recommended European Union levels of 25 ng kg-1 by more than an order of magnitude. Also, several (66%) of them contained detectable concentrations of deoxynivalenol with two samples (6.9%) exceeding European Union guidelines for baby food products (200 MUg kg-1) and 51.7% samples with DON levels that can lead to dietary intake higher than 1 MUg kg-1 recommended by the joint FAO/WHO expert committee on food additives. None of the samples contained aflatoxins B1, B2, G1 and G2. The results, therefore, suggest that complementary feeding can put Indian infants and toddlers at risk of simultaneous exposures to deoxynivalenol and aflatoxin M1 and warrant an urgent in-depth research to track, increase surveillance and reduce mycotoxin contamination of baby foods manufactured in India.

PMID- 30300725 TI - RIFM fragrance ingredient safety assessment, 1,1-diethoxyheptane, CAS Registry Number 688-82-4. AB - The use of this material under current conditions is supported by existing information. 1,1-Diethoxyheptane was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from the read-across analog octanal dimethyl acetal (CAS # 10022-28-3) show that 1,1-diethoxyheptane is not expected to be genotoxic. Based on the application of the non-reactive DST, 1,1-diethoxyheptane does not present a concern for skin sensitization. The repeated dose, developmental and reproductive, and local respiratory toxicity endpoints were completed using the TTC for a Cramer Class I material (0.03 mg/kg/day, 0.03 mg/kg/day, and 1.4 mg/day, respectively). The phototoxicity/photoallergenicity endpoint was completed based on UV spectra. The environmental endpoints were evaluated; 1,1 diethoxyheptane was found not to be PBT as per the IFRA Environmental Standards, and its risk quotients, based on its current volume of use in Europe and North America (i.e., PEC/PNEC), are <1. PMID- 30300726 TI - Maternal BDE-209 exposure during lactation perturbs steroidogenesis, germ cell kinetics and THRalpha1 expression in testes of prepubertal mice offspring. AB - Decabromodiphenyl ether (BDE-209), a congener of polybrominated diphenyl ethers (PBDEs), is used as flame retardant and affects thyroid homeostasis. Thyroid hormones (THs) play crucial role in Leydig cell differentiation and steroidogenesis during early life. Present study examined the effect of maternal BDE-209 exposure during lactation on testicular steroidogenesis and spermatogenesis in relation to thyroid hormone receptor alpha 1 (THRalpha1) and possible mechanism(s) of its action in prepubertal Parkes mice offspring. Lactating female Parkes mice were orally gavaged with 500, and 700 mg/kg body weight of BDE-209 in corn oil from postnatal day (PND) 1 to PND 28. Lactating mothers and male pups were sacrificed on PND 28. Maternal BDE-209 exposure markedly affected testicular histopathology, steroidogenesis and germ cell dynamics with downregulated expressions of various steroidogenic markers in mice offspring. Serum THs levels were markedly reduced in both pups and lactating mothers compared to controls. Expression of proliferating cell nuclear antigen and THRalpha1 also deceased in testes of BDE-209-exposed mice offspring. In silico analysis by molecular docking was performed successfully for steroidogenic facor-1 (SF-1) and THRalpha1 with BDE-209 and T3. Maternal BDE-209 exposure during lactation affects testicular steroidogenesis, spermatogenesis and expression of THRalpha1 in prepubertal mice offspring through downregulation of SF-1.

PMID- 30300728 TI - Development and validation of a ready to use cryo-EROD assay for the standardized screening of dioxins and dioxin-like compounds in foodstuffs. AB - Recent European regulations have indicated the need for new bioanalytical screening methods capable of monitoring dioxin and dioxin-like compounds in foodstuffs and environmental samples, cost-effectively and with a quicker turnaround. Cryo-cells of the hepatic H4IIE line preserved in 96-well plates were exposed to sample extracts prepared from various foodstuffs and analysed for their content of dioxins and dioxin-like compounds by means of the 7 Ethoxyresorufin-O-Deethylase (EROD)-assay in two laboratories. Assay data were compared between both laboratories and results from instrumental analysis used as a confirmatory method. Additionally, cut-off values for the different studied matrices were derived. The current European regulation regarding methods of analysis for the control of foodstuffs was applied with the aim of determining the feasibility of the cryo-methodology. Results obtained in both laboratories were in congruence with the required validation parameters of the Commission Regulation (EU) No 2017/644. Cut-off values should be established matrix dependent to reduce the rate of false compliant results and to keep the rate of false non-compliant results under control. In summary, the ready-to-use cryo assay method for the bioanalytical screening of foodstuffs in control laboratories without cell-culture facilities has successfully proven to be accurate, far quicker and more cost effective than current methods.

PMID- 30300731 TI - Reduced-Intensity Conditioning with Fludarabine, Melphalan, and Total Body Irradiation for Allogeneic Hematopoietic Cell Transplantation: The Effect of Increasing Melphalan Dose on Underlying Disease and Toxicity. AB - Disease relapse and toxicity are the shortcomings of reduced-intensity conditioning (RIC) for allogeneic hematopoietic cell transplantation (alloHCT). We hypothesized that adding total body irradiation (TBI) to and decreasing melphalan (Mel) from a base RIC regimen of fludarabine (Flu) and Mel would increase cytoreduction and improve disease control while decreasing toxicity. We performed a phase II trial of Flu 160 mg/m2, Mel 50 mg/m2, and TBI 400 cGy (FluMelTBI-50, n = 61), followed by a second phase II trial of Flu 160 mg/m2, Mel 75 mg/m2, and TBI 400 cGy (FluMelTBI-75, n = 94) as RIC for alloHCT. Outcomes were compared with a contemporaneous cohort of 162 patients who received Flu 125 mg/m2 and Mel 140 mg/m2. Eligibility criteria were equivalent for all 3 regimens. All patients were ineligible for myeloablative/intensive conditioning. The median (range) follow-up for all patients was 51 (15 to 103) months. Day 100 donor lymphoid chimerism and transplant-related mortality, neutrophil and platelet engraftment, acute and chronic graft versus host disease incidence, overall survival (OS), and progression-free survival (PFS) were equivalent between FluMel, FluMelTBI-50, and FluMelTBI-75. Stomatitis was decreased for FluMelTBI versus FluMel (P < .01). PFS for patients not in complete remission on alloHCT was improved for FluMelTBI-75 versus FluMel (P = .03). On multivariate analysis, OS (P = .05) and PFS (P = .05) were significantly improved for FluMelTBI-75 versus FluMel. FluMelTBI-75 is better tolerated than FluMel, with improved survival and disease control. PMID- 30300732 TI - Interventions for common mental health problems among university and college students: A systematic review and meta-analysis of randomized controlled trials. AB - Common mental health problems (CMHPs), such as depression, anxiety disorder, obsessive-compulsive disorder (OCD), and post-traumatic stress disorder (PTSD) are internalizing disorders with high comorbidity. University and college students are under many stressors and transitional events, and students fall within the age range when CMHPs are at their developmental peak. Compared to the expanded effort to explore and treat CMHPs, there has been no a meta-analysis that comprehensively reviewed the interventions for CMHPs and examined the effects of interventions for CMHPs in college students. The objective of this review is to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) examining interventions for CMHPs among university and college students and to estimate their post-intervention effect size (ES), as well as follow-up ES, for depression, anxiety disorder, OCD and PTSD separately. Meta-analytic procedures were conducted in accordance with PRISMA guidelines. We reviewed 7768 abstracts from which 331 full-text articles were reviewed and 51 RCTs were included in the analysis. We found moderate effect sizes for both depression (Hedges' g = -0.60) and anxiety disorder (Hedges' g = -0.48). There was no evidence that existing interventions for OCD or PTSD were effective in this population. For interventions with high number of papers, we performed subgroup analysis and found that cognitive behavioral therapy (CBT) and mindfulness-based interventions were effective for both depression and generalized anxiety disorder (GAD), and attention/perception modification was effective for GAD; other interventions (i.e. art, exercise and peer support) had the highest ES for both depression and GAD among university and college students. PMID- 30300734 TI - Albuminuria and other renal damage biomarkers detect acute kidney injury soon after acute ingestion of oxalic acid and potassium permanganate. AB - BACKGROUND: Deliberate self-poisoning with a combination washing powder containing oxalic acid (H2C2O4) and potassium permanganate (KMnO4) is a significant medical problem in the Southern Province of Sri Lanka. Acute kidney injury (AKI) is a frequent consequence. Biomarkers for early diagnosis of nephrotoxicity could guide appropriate supportive therapies. METHODS: We investigated the performance of three serum biomarkers and nine urinary biomarkers in 85 patients in an ongoing multicenter prospective cohort study in Sri Lanka exploring AKI following poisoning. RESULTS: Sixty two (62/85, 73%) patients developed AKI (acute kidney injury network, AKIN, criteria). Early and rapid increases in serum creatinine (sCr) peaking on day 3 were observed in AKIN stage 2 and 3 patients. In these patients, serum cystatin C (sCysC) rose more gradually but also peaked on day 3. Biomarker concentrations (normalized to urinary creatinine) of urinary albumin (uAlbumin), clusterin (uClusterin), beta-2 microglobulin (uB2M), osteopontin (uOPN), neutrophil gelatinase-associated lipocalin (uNGAL) and kidney injury molecule-1 (uKIM-1) in the AKIN2/3 group increased above the 95th centile concentration of the healthy population. Within 8 h of ingestion, the normalized uAlbumin and sCysC predicted AKIN2/3 with respective area under receiver operating characteristic curve, AUC-ROC values, of 0.94 (95% CI 0.86-1.00) and 0.85 (95% CI 0.76-0.95). CONCLUSIONS: Urinary albumin was the best performing AKI biomarker following ingestion of H2C2O4/KMnO4. This may reflect glomerular injury and/or proximal tubular injury. The urinary albumin concentrations observed in this study could generally be detected using albumin specific dipstick methods, easily available even in resource poor settings. PMID- 30300735 TI - Endothelial nitric oxide synthase enhancer AVE3085 reverses endothelial dysfunction induced by homocysteine in human internal mammary arteries. AB - Homocysteine (Hcy) is an independent risk factor for endothelial dysfunction in cardiovascular diseases. We hypothesized that the eNOS transcription enhancer AVE3085 may protect the endothelial function damaged by Hcy in the human internal mammary artery (IMA). Cumulative concentration-relaxation curves to acetylcholine (-10 to -4.5 log mol/L) or sodium nitroprusside were established in IMA from patients undergoing coronary artery surgery precontracted by U46619 (-8 log mol/L) in the absence/presence of Hcy (100 MUmol/L) with/without AVE3085 (30 MUmol/L) in vitro in a myograph. RT-qPCR and ELISA were used to quantify the mRNA and protein levels of eNOS. Colorimetric assay method was used to detect the production of nitric oxide (NO). Maximal relaxation was significantly attenuated by Hcy in human IMA. Co-incubation with AVE3085 protected endothelium from the impairment by Hcy and increased the production of NO. Exposure to Hcy for 24 h downregulated eNOS protein expression (P < 0.05) whereas it upregulated the expression of eNOS at mRNA levels (P < 0.05). The presence of AVE3085 in addition to Hcy significantly increased the eNOS protein (P < 0.05) and slightly decreased the mRNA level. The study for the first time revealed that in the human blood vessels (IMA) the clinically-relevant high concentration of Hcy directly causes endothelial dysfunction by downregulating eNOS protein that may be reversed by AVE3085. These findings not only provide new direction for protecting endothelium during coronary artery bypass grafting and improving long-term patency of the grafts, but also provide evidence to the use of eNOS enhancer in the patients with endothelial dysfunction in various pathological conditions.

Previous evidence from our lab has shown that iAs can increase DM risk by impairing mitochondrial metabolism, one of the key steps in the regulation of glucose-stimulated insulin secretion (GSIS) in pancreatic beta cells. The goal of the current study was to compare the effects of iAs on GSIS and mitochondrial function in INS-1 832/13 beta-cells with those of Cd, Mn, and Zn, and to evaluate effects of binary mixtures of these metals. As expected, 24 hour exposure to iAs (arsenite, >=1 MUM) significantly inhibited GSIS as did Cd (5 MUM) and Mn (12.5, 25, or 50 MUM). Zn had no effects on GSIS at concentrations up to 50 MUM. Mitochondrial function was assessed by measuring oxygen consumption rate (OCR) after glucose stimulation and during simulated mitochondrial stress. While both iAs and Mn impaired mitochondrial function (inhibiting OCR, maximal respiration, and/or spare respiratory capacity of mitochondria), no significant effects were found in cells exposed to Cd. Interestingly, no additive or synergistic effects on GSIS or OCR were observed in binary mixtures of iAs with either Mn or Cd. These data suggest that Mn, like iAs, may inhibit GSIS by impairing mitochondrial function, whereas Cd may target other mechanisms that regulate GSIS in beta-cells. PMID- 30300736 TI - An MBT domain containing anti-lipopolysaccharide factor (PtALF8) from Portunus trituberculatus is involved in immune response to bacterial challenge. AB - Anti-lipopolysaccharide factors are effective antimicrobial peptides that can bind and neutralize lipopolysaccharide (LPS). In the present study, a new sequence encoding for ALF (designated as PtALF8) was cloned by suppression subtractive hybridization method using ovary of swimming crab Portunus trituberculatus as material. The full-length cDNA of PtALF8 consisted of 531 bp with an ORF of 348 bp encoding a peptide of 115 amino acids containing a putative signal peptide of 19 amino acids. The mature PtALF8 had a predicted molecular weight (MW) of 11.28 kDa and theoretical isoelectricpoint (pI) of 5.11. The PtALF8 contains an MBT domain which was not found in the other 7 isoforms of ALF reported in P. trituberculatus. Unlike most ALFs expressed in hemocytes, PtALF8 transcript was predominantly detected in hepatopancreas. After challenge with Vibrio alginolyticus, the temporal expression level of PtALF8 transcript in hemocytes reached the highest level at 3 h, then decreased to the lowest level at 24 h, and started to increase at 48 h. The recombinant protein showed antimicrobial and bactericidal activity against several bacteria, such as Gram positive bacteria, Staphylococcus aureus, Micrococcus luteus and Gram-negative bacteria, V. alginolyticus, indicated that the PtALF8 isoform might play protective function against invading bacteria in P. trituberculatus. PMID- 30300737 TI - Two novel serine proteases from Scylla paramamosain involved in the synthesis of anti-lipopolysaccharide factors and activation of prophenoloxidase system. AB - Serine proteases (SPs) are important in various immune responses, including prophenoloxidase (proPO) activation, antimicrobial peptides (AMPs) synthesis, and hemolymph coagulation in invertebrates. In this study, SP3 and SP5 of mud crab (Scylla paramamosain) were studied. SP3 and SP5 were expressed in all examined tissues (mainly in hemocytes), and are associated with the immune responses of mud crab to Vibrio parahemolyticus and Staphylococcus aureus, as well as interacted with TRAF6, and are involved in the activation of anti lipopolysaccharide factors (ALFs) probably through the TLR/NF-kappaB pathway. Depletion of SP3 inhibited the expression of ALF1, ALF2, ALF3, and ALF6, while knockdown of SP5 significantly decreased ALF5, and ALF6. Furthermore, both SP5 and TRAF6 regulated the PO activity in the hemolymph of mud crab. Overexpression assay showed that both SP3 and SP5 could enhance the promoter activities of ALFs in mud crab. Taken together, the results of this study indicate that SP3 and SP5 might play important roles in the immune system of mud crab against pathogen invasion. PMID- 30300738 TI - Oral delivery of Bacillus subtilis spores expressing grass carp reovirus VP4 protein produces protection against grass carp reovirus infection. AB - Grass carp (Ctenopharyngodon idellus) hemorrhagic disease (GCHD), caused by grass carp reovirus (GCRV), has given rise to an enormous loss in grass carp industry during the past years. Up to date, vaccination remained to be the most effective way to protect grass carp from GCHD. Oral vaccination is of major interest due to its advantages of noninvasive, time-saving, and easily-operated. The introduction of oral vaccination has profound impact on aquaculture industry because of its feasibility of extensive application for fish in various size and age. However, the main challenge in developing oral vaccine is that antigens are easily degraded and are easy to induce tolerance. Bacillus subtilis (B. subtilis) spores would be an ideal oral vaccine delivery system for their robust specialty, gene operability, safety and adjuvant property. VP4 protein is the major outer capsid protein encoded by GCRV segment 6 (S6), which plays an important role in viral invasion and replication. In this study, we used B. subtilis spores as the oral delivery system and successfully constructed the B. subtilis CotC-VP4 recombinant spores (CotC-VP4 spores) to evaluate its protective efficacy in grass carp. Grass carp orally immunized with CotC-VP4 spores showed a survival rate of 57% and the relative percent survival (RPS) of 47% after the viral challenge. Further, the specific IgM levels in serum and the specific IgZ levels in intestinal mucus were significantly higher in the CotC-VP4 group than those in the Naive group. The immune-related genes including three innate immune-related genes (IL-4/13A, IL 4/13B, CSF1R), four adaptive immune-related genes (BAFF, CD4L, MHC-II, CD8), three inflammation-related genes (IL-1beta, TNF-alpha, TGF-beta) and interferon type I (IFN-I) related signaling pathway genes were significantly up-regulated in the CotC-VP4 group. The study demonstrated that the CotC-VP4 spores produced protection in grass carp against GCRV infection, and triggered both innate and adaptive immunity post oral immunization. This work highlighted that Bacillus subtilis spores were powerful platforms for oral vaccine delivery, and the combination of Bacillus subtilis spores with GCRV VP4 protein was a promising oral vaccine. PMID- 30300739 TI - Responses of Mytilus galloprovincialis to challenge with the emerging marine pathogen Vibrio coralliilyticus. AB - Vibrio coralliilyticus has emerged as a coral pathogen of concern throughout the Indo-Pacific reef. The interest towards understanding its ecology and pathogenic potential has increased since V. coralliilyticus was shown to be strongly virulent also for other species; in particular, it represents a serious threat for bivalve aquaculture, being one of the most important emerging pathogen responsible for oyster larval mortalities worldwide. V. coralliilyticus has a tightly regulated temperature-dependent virulence and it has been related to mass mortalities events of benthic invertebrates also in the temperate northwestern Mediterranean Sea. However, no data are available on the effects of V. coralliilyticus in the mussel Mytilus galloprovincialis, the most abundant aquacultured species in this area. In this work, responses of M. galloprovincialis to challenge with V. coralliilyticus (ATCC BAA-450) were investigated. In vitro, short term responses of mussel hemocytes were evaluated in terms of lysosomal membrane stability, bactericidal activity, lysozyme release, ROS and NO production, and ultrastructural changes, evaluated by TEM. In vivo, hemolymph parameters were measured in mussels challenged with V. coralliilyticus at 24h p.i. Moreover, the effects of V. coralliilyticus on mussel early embryo development (at 48 hpf) were evaluated. The results show that both in vitro and in vivo, mussels were unable to activate immune response towards V. coralliilyticus, and that challenge mainly induced lysosomal stress in the hemocytes. Moreover, V. coralliilyticus showed a strong and concentration dependent embryotoxicity. Overall, the results indicate that, although M. galloprovincialis is considered a resistant species to vibrio infections, the emerging pathogen V. coralliilyticus can represent a potential threat to mussel aquaculture. PMID- 30300740 TI - Effects of glycinin and beta-conglycinin on growth performance and intestinal health in juvenile Chinese mitten crabs (Eriocheir sinensis). AB - This study investigates the effects of two soybean antigens (glycinin and beta conglycinin) as an antinutritional substance in the diet on the growth, digestive ability, intestinal health and microbiota of juvenile Chinese mitten crabs (Eriocheir sinensis). The isonitrogenous and isolipidic diets contained two soybean antigens at two levels each (70 and 140 g/kg beta-conglycinin, 80 and 160 g/kg glycinin) and a control diet without beta-conglycinin or glycinin supplementation, and were used respectively to feed juvenile E. sinensis for seven weeks. Dietary inclusion of either glycinin or beta-conglycinin significantly reduced crab survival and weight gain. The crabs fed diets containing soybean antigens had higher malondialdehyde concentrations and lower catalase activities in the intestine than those in the control. The activities of trypsin and amylase in the intestine were suppressed by dietary beta-conglycinin and glycinin. Dietary glycinin or beta-conglycinin impaired the immunity and morphological structure of intestine, especially the peritrophic membrane. The mRNA expression of constitutive and inducible immune responsive genes (lipopolysaccharide-induced TNF-alpha factor and interleukin-2 enhancer-binding factor 2) increased while the mRNA expression of the main genes related to the structural integrity peritrophic membrane (peritrophin-like gene and peritrophic 2) significantly decreased in the groups with soybean antigen addition. Soybean antigen could also change the intestinal microbial community. The abundance of pathogenic bacteria (Ochrobactrum, Burkholderia and Pseudomonas) increased significantly in both soybean antigen groups. Although pathogenic bacteria Vibrio were up-regulated in the glycinin group, the abundance of Dysgonomonas that degraded lignocellulose and ameliorated the gut environment decreased in the glycinin group. This study indicates that existence of soybean antigens (glycinin or beta-conglycinin) could induce gut inflammation, reshape the community of gut microbiota, and cause digestive dysfunction, ultimately leading to impaired growth in crabs. PMID- 30300741 TI - Identification and characterization of a carboxypeptidase N1 from red lip mullet (Liza haematocheila); revealing its immune relevance. AB - Complement system orchestrates the innate and adaptive immunity via the activation, recruitment, and regulation of immune molecules to destroy pathogens. However, regulation of the complement is essential to avoid injuries to the autologous tissues. The present study unveils the characteristic features of an important complement component, anaphylatoxin inactivator from red lip mullet at its molecular and functional level. Mullet carboxypeptidase N1 (MuCPN1) cDNA sequence possessed an open reading frame of 1347 bp, which encoded a protein of 449 amino acids with a predicted molecular weight of 51 kDa. In silico analysis discovered two domains of PM14-Zn carboxypeptidase and a C-terminal domain of M14 N/E carboxypeptidase, two zinc-binding signature motifs, and an N-glycosylation site in the MuCPN1 sequence. Homology analysis revealed that most of the residues in the sequence are conserved among the other selected homologs. Phylogeny analysis showed that MuCPN1 closely cladded with the Maylandia zebra CPN1 and clustered together with the teleostean counterparts. A challenge experiment showed modulated expression of MuCPN1 upon polyinosinic:polycytidylic acid and Lactococcus garviae in head kidney, spleen, gill, and liver tissues. The highest upregulation of MuCPN1 was observed 24 h post infection against poly I:C in each tissue. Moreover, the highest relative expressions upon L. garviae challenge were observed at 24 h post infection in head kidney tissue and 48 h post infection in spleen, gill, and liver tissues. MuCPN1 transfected cells triggered a 2.2-fold increase of nitric oxide (NO) production upon LPS stimulation compared to the un transfected controls suggesting that MuCPN1 is an active protease which releases arginine from complement C3a, C4a, and C5a. These results have driven certain way towards enhancing the understanding of immune role of MuCPN1 in the complement defense mechanism of red lip mullet. PMID- 30300742 TI - IgM and IgD heavy chains of yellow catfish (Pelteobagrus fulvidraco): Molecular cloning, characterization and expression analysis in response to bacterial infection. AB - Three different immunoglobulin (Ig) isotypes, namely IgM, IgD, and IgT/IgZ have been described in most teleost, among which IgM and IgT are considered crucial in systematic and mucosal immunity, respectively. However, some teleost have no IgT/IgZ and it is unclear how other Ig isotypes interact to perform immune protective roles in both systematic and mucosal sites. In this study, the complete cDNA sequences of IgM and IgD heavy chains were cloned and analyzed from yellow catfish (Pelteobagrus fulvidraco). The full-length cDNA of Pf-IgM and Pf IgD heavy chains contained an open reading frame (ORF) of 1710 and 2991 bp encoding a predicted protein of 570 and 997 amino acids, respectively. Tissue specific expression analysis indicated that both IgM and IgD were highly expressed in kidney and spleen, and higher expression levels were found at zygote and 13th day post hatching during early development. Multiple sequence alignment and phylogenetic analysis showed IgM and IgD of yellow catfish are closely related to other fish of Siluriformes. Moreover, we also constructed the infection model of yellow catfish with bacteria (Flavobacterium columnare G4) for the first time to study the function of Pf-IgM and Pf-IgD heavy chain genes in immune response. Quantitative real-time PCR (qRT-PCR) showed that significantly up-regulated expression of Pf-IgM was not only detected in liver and spleen, but also in mucosal tissues including skin and intestine, while Pf-IgD was just significantly increased in liver and spleen, which might suggest the main immune protecting roles of IgM in mucosal tissues of yellow catfish. PMID- 30300743 TI - Quantitative mass spectrometry to identify protein markers for diagnosis of malignant pleural mesothelioma. AB - Malignant pleural mesothelioma (MPM) is a devastating malignancy with a prognosis of <12 months. Even with bans on the use of asbestos in most Western countries, the incidence is still increasing due to the long latency periods between exposure and development of the disease. Diagnosis is often delayed due to invasive biopsies and lack of distinguishable markers. Patients frequently present with pleural effusions months to years before a radiologically detectable mass appears. This study aimed to investigate the proteome of pleural effusions taken from patients with MPM, adenocarcinoma and benign conditions in an attempt to identify a biomarker for early diagnosis. We identified several proteins that may be possible targets and warrant further investigation. Due to the predominance of up regulated proteins involved in VEGF signalling in MPM, we analysed VEGFA levels in effusions and found a strong correlation between VEGFA levels and survival in MPM. PMID- 30300744 TI - The effect of a telephone-based self-management program led by nurses on self care behavior, biological index for cardiac function, and depression, in ambulatory heart failure patients. AB - PURPOSE: This study was conducted to examine the effects of a telephone-based self-management support program led by nurses on self-care behavior, biological index for cardiac function and depression. METHODS: This study is a quasi experiment in nonequivalent control group design. 36 heart failure patients were conducted in medical treatment at the hospital (18 heart failure patients in experimental group and 18 heart failure patients in control group). The experimental group (n=18) received the telephone-based self-management support program, which included a 30-minute face-to-face education session and 4 telephone consultation and education sessions. The face-to-face education session was conducted at the first visit to the out-patient clinic. Thereafter, weekly telephone consultations and education sessions were performed for 4 weeks. Data were analyzed using descriptive statistics, Chi-square test, Fisher's exact test, independent t-test, paired t-test, repeated measures ANOVA using the SPSS/WIN 21.0. RESULTS: The participants in the experimental group showed significantly increased self-care behavior scores (t=6.65, p<.001), decreased NT-proBNP level (U=-2.28, p=.022), improved LV EF values (t=2.24, p=.032), and decreased depression scores (t=-3.49, p=.001) compared to the control group. CONCLUSION: The findings indicate that the telephone-based self-management program is an effective intervention to improve self-management in heart failure patients. PMID- 30300745 TI - Age-related differences in the activation of the mentalizing- and reward-related brain regions during the learning of others' true trustworthiness. AB - Behavioral studies suggest that older adults may be less adept than younger adults at remembering information contradicting their first impressions about others' trustworthiness. To identify the neural bases associated with such age related differences, we measured the brain activity of older and younger participants using functional magnetic resonance imaging while they processed feedback on whether their initial trustworthiness impressions of stimulus persons, whose true trustworthiness had been predetermined, were right or wrong. Of special interest was the activation in mentalizing- (e.g., medial prefrontal cortex) and reward-related brain regions (e.g., striatum), which are known to be involved in impression formation and feedback learning, respectively. The reduction in the striatal responses to impression-contradicting versus impression confirming feedback was greater in older than in younger participants. The activation of some mentalizing-related regions (medial prefrontal cortex and precuneus) was lower in older than younger participants; however, it was not modulated by impression-feedback congruency. The results suggest that age-related differences in the striatum engagement may underlie older adults' inefficiency in learning impression-incongruent information about others' trustworthiness. PMID- 30300746 TI - Dehydration during egg production alters egg composition and yolk immune function. AB - Parent-offspring conflicts occur when resources are limited for allocation, and, historically, energy has been the primary currency of focus when examining these trade-offs. Water is a fundamental resource that has received far less consideration for parent-offspring conflicts. Previous research suggests that, when water is limited, reproductive females are compromised in favor of developing embryos. However, these studies limited their assessments to standard metrics such as clutch size and mass. We tested the hypothesis that the mother offspring conflict over limited water resources leads to finer scale morphological and physiological impacts on the eggs in Children's pythons (Antaresia childreni). We predicted that water deprivation during gravidity alters female investment into her eggs, impacting egg water content and shell development. Additionally, we predicted that the yolk in these dehydrated eggs would have enhanced immune performance metrics, as has been documented in dehydrated adults. We found that eggs from water-deprived females were dehydrated as indicated by reduced percent water and greater yolk osmolality compared to eggs from females that received ad libitum water. We also found that eggs from dehydrated mothers had thinner shells and higher water loss rates. The impacts were not entirely negative as dehydrated eggs had higher antimicrobial capabilities. Also, thinner and more permeability eggshells might allow for elevated rates of rehydration from nest substrate. Overall, by examining an array of egg traits, we demonstrated that dehydration of gravid females impacts the eggs, not just the females as previously reported. As a result, the mother offspring conflicts are indeed two-sided. PMID- 30300747 TI - Role of flow-sensitive microRNAs and long noncoding RNAs in vascular dysfunction and atherosclerosis. AB - Atherosclerosis is the primary underlying cause of myocardial infarction, ischemic stroke, and peripheral artery disease. The disease preferentially occurs in arterial regions exposed to disturbed blood flow, in part, by altering expression of flow-sensitive coding- and non-coding genes. In this review, we summarize the role of noncoding RNAs, [microRNAs (miRNAs) and long noncoding RNAs(lncRNAs)], as regulators of gene expression and outline their relationship to the pathogenesis of atherosclerosis. While miRNAs are small noncoding genes that post-transcriptionally regulate gene expression by targeting mRNA transcripts, the lncRNAs regulate gene expression by diverse mechanisms, which are still emerging and incompletely understood. We focused on multiple flow sensitive miRNAs such as, miR-10a, -19a, -23b, -17~92, -21, -663, -92a, -143/145, -101, -126, -712, -205, and -155 that play a critical role in endothelial function and atherosclerosis by targeting inflammation, cell cycle, proliferation, migration, apoptosis, and nitric oxide signaling. Flow-dependent regulation of lncRNAs is just emerging, and their role in vascular dysfunction and atherosclerosis is unknown. Here, we discuss the flow-sensitive lncRNA STEEL along with other lncRNAs studied in the context of vascular pathophysiology and atherosclerosis such as MALAT1, MIAT1, ANRIL, MYOSLID, MEG3, SENCR, SMILR, LISPR1, and H19. Also discussed is the use of these noncoding RNAs as potential biomarkers and therapeutics to reduce and regress atherosclerosis. PMID- 30300748 TI - Cationic carrier peptide enhances cerebrovascular targeting of nanoparticles in Alzheimer's disease brain. AB - Accumulation of amyloid beta (Abeta) peptides in the cerebral vasculature, referred to as cerebral amyloid angiopathy (CAA), is widely observed in Alzheimer's disease (AD) brain and was shown to accelerate cognitive decline. There is no effective method for detecting cerebrovascular amyloid (CVA) and treat CAA. The targeted nanoparticles developed in this study effectively migrated from the blood flow to the vascular endothelium as determined by using quartz crystal microbalance with dissipation monitoring (QCM-D) technology. We also improved the stability, permeability, and blood-brain barrier (BBB) transcytosis of targeted nanoparticles by coating them with a cationic BBB penetrating peptide (K16ApoE). The K16ApoE-Targeted nanoparticles demonstrated specific targeting of vasculotropic DutchAbeta40 peptide accumulated in the cerebral vasculature. Moreover, K16ApoE-Targeted nanoparticles demonstrated significantly greater uptake into brain and provided specific MRI contrast to detect brain amyloid plaques. PMID- 30300749 TI - Trimodal synergistic antitumor drug delivery system based on graphene oxide. AB - A multifunctional antitumor drug delivery system was synthesized based on graphene oxide (GO) for near-infrared (NIR) light controlling chemotherapeutic/photothermal (PTT) /photodynamic (PDT) trimodal synergistic therapy. The system named ICG-Wed-GO was formed by co-loading wedelolactone (Wed) and indocyanine green (ICG) on the surface of GO through pi-pi stacking interaction. Under NIR laser irradiation, ICG-Wed-GO could effectively absorb and transform optical energy to heat, generate reactive oxygen species (ROS) to ablating and damage tumor cells. The temperature of ICG-Wed-GO solution reached up to 79.4 degrees C in 10 min with NIR irradiation. In in vitro and in vivo study, ICG-Wed-GO showed excellent antitumor effect. After 14-day treatment of ICG-Wed-GO with NIR laser irradiation, the tumor disappeared completely on tumor bearing mice. The low biotoxicity of ICG-Wed-GO was also proved. The system achieved the synergistic trimodal chemotherapeutic/photothermal/photodynamic treatment and demonstrated excellent antitumor effect, which is expected to have a greater potential for cancer therapy. PMID- 30300750 TI - Self-assembling lisofylline-fatty acid conjugate for effective treatment of diabetes mellitus. AB - Lisofylline is an anti-inflammatory agent with proven anti-diabetic activity. Its high solubility and rapid metabolism results in poor bioavailability and short half-life, limiting its clinical utility. We have synthesized Lisofylline Linoleic acid (LSF-LA) conjugate which self-assembled into micelles (156.9 nm; PDI 0.187; CMC 1 MUg/mL; aggregation number 54) without any surfactant and showed enhanced cellular uptake. It protected MIN6 insulinoma cells from cytokine induced cell death and enhanced insulin production under inflammatory conditions. It also suppressed the proliferation of activated peripheral blood mononuclear cells and reduced the production of inflammatory cytokines, IFN-gamma and TNF alpha. LSF-LA micelles exhibited reduced protein binding, significantly higher half-life (5.7-fold) and higher apparent volume of distribution (5.3-fold) than free LSF. In T1D animals, reduced blood glucose levels were observed at a reduced dose (~15 mg/kg, once daily of LSF-LA micelles vs. 25 mg/kg, twice daily of free LSF) that was further confirmed by immunohistochemical analysis. PMID- 30300751 TI - Automatic segmentation of the spinal cord and intramedullary multiple sclerosis lesions with convolutional neural networks. AB - The spinal cord is frequently affected by atrophy and/or lesions in multiple sclerosis (MS) patients. Segmentation of the spinal cord and lesions from MRI data provides measures of damage, which are key criteria for the diagnosis, prognosis, and longitudinal monitoring in MS. Automating this operation eliminates inter-rater variability and increases the efficiency of large throughput analysis pipelines. Robust and reliable segmentation across multi-site spinal cord data is challenging because of the large variability related to acquisition parameters and image artifacts. In particular, a precise delineation of lesions is hindered by a broad heterogeneity of lesion contrast, size, location, and shape. The goal of this study was to develop a fully-automatic framework - robust to variability in both image parameters and clinical condition - for segmentation of the spinal cord and intramedullary MS lesions from conventional MRI data of MS and non-MS cases. Scans of 1042 subjects (459 healthy controls, 471 MS patients, and 112 with other spinal pathologies) were included in this multi-site study (n = 30). Data spanned three contrasts (T1-, T2-, and T2*-weighted) for a total of 1943 vol and featured large heterogeneity in terms of resolution, orientation, coverage, and clinical conditions. The proposed cord and lesion automatic segmentation approach is based on a sequence of two Convolutional Neural Networks (CNNs). To deal with the very small proportion of spinal cord and/or lesion voxels compared to the rest of the volume, a first CNN with 2D dilated convolutions detects the spinal cord centerline, followed by a second CNN with 3D convolutions that segments the spinal cord and/or lesions. CNNs were trained independently with the Dice loss. When compared against manual segmentation, our CNN-based approach showed a median Dice of 95% vs. 88% for PropSeg (p <= 0.05), a state-of-the-art spinal cord segmentation method. Regarding lesion segmentation on MS data, our framework provided a Dice of 60%, a relative volume difference of -15%, and a lesion-wise detection sensitivity and precision of 83% and 77%, respectively. In this study, we introduce a robust method to segment the spinal cord and intramedullary MS lesions on a variety of MRI contrasts. The proposed framework is open-source and readily available in the Spinal Cord Toolbox. PMID- 30300753 TI - High detection sensitivity with antibody-based PET radioligand for amyloid beta in brain. AB - PET imaging of amyloid-beta (Abeta) deposits in brain has become an important aid in Alzheimer's disease diagnosis, and an inclusion criterion for patient enrolment into clinical trials of new anti-Abeta treatments. Available PET radioligands visualizing Abeta bind to insoluble fibrils, i.e. Abeta plaques. Levels of prefibrillar Abeta forms, e.g. soluble oligomers and protofibrils, correlate better than plaques with disease severity and these soluble species are the neurotoxic form of Abeta leading to neurodegeneration. The goal was to create an antibody-based radioligand, recognizing not only fibrillary Abeta, but also smaller and still soluble aggregates. We designed and expressed a small recombinant bispecific antibody construct, di-scFv 3D6-8D3, targeting the Abeta N terminus and the transferrin receptor (TfR). Natively expressed at the blood brain barrier (BBB), TfR could thus be used as a brain-blood shuttle. Di-scFv 3D6 8D3 bound to Abeta1-40 with high affinity and to TfR with moderate affinity. Di scFv [124I]3D6-8D3 was injected in two transgenic mouse models overexpressing human Abeta and wild-type control mice and PET scanned at 14, 24 or 72 h after injection. Di-scFv [124I]3D6-8D3 was retained in brain of transgenic animals while it was cleared from wild-type lacking Abeta. This difference was observed from 24 h onwards, and at 72 h, 18 months old transgenic animals, with high load of Abeta pathology, displayed SUVR of 2.2-3.5 in brain while wild-type showed ratios close to unity. A subset of the mice were also scanned with [11C]PIB. Again wt mice displayed ratios of unity while transgenes showed slightly, non significantly, elevated SUVR of 1.2, indicating improved sensitivity with novel di-scFv [124I]3D6-8D3 compared with [11C]PIB. Brain concentrations of di-scFv [124I]3D6-8D3 correlated with soluble Abeta (p < 0.0001) but not with total Abeta, i.e. plaque load (p = 0.34). We have successfully created a small bispecific antibody-based radioligand capable of crossing the BBB, subsequently binding to and visualizing intrabrain Abeta in vivo. The radioligand displayed better sensitivity compared with [11C]PIB, and brain concentrations correlated with soluble neurotoxic Abeta aggregates.

PMID- 30300755 TI - Microbiological features of indigenous typhoid cases in Taiwan and relatedness to imported cases, 2001-2014: A cross-sectional analysis. AB - BACKGROUND: Typhoid fever was rare in Taiwan but approximately two-thirds of the cases were indigenous. The transmission source of the indigenous cases and the relatedness to the imported cases remained unknown. METHODS: Patients with any site culture positive for Salmonella enterica serovar Typhi were identified in a teaching hospital during 2001-2014. The isolates were determined for antibiotic susceptibilities, pulsed-field gel electrophoresis (PFGE) types and single nucleotide polymorphisms (SNP) types. RESULTS: A total of 64 typhoid episodes were identified in 63 patients. Seventeen episodes (26.6%) were imported and a majority (10, 58.8%) of them were from Indonesia. The clinical manifestations, outcomes of patients and antibiograms of isolates were similar between indigenous and imported cases. 63.3% of the isolates were ciprofloxacin-resistant. The distributions of PFGE and SNP types did not differ significantly between indigenous and imported isolates, either (P = 0.191 and 0.124, respectively). Identical PFGE pattern could be identified in indigenous isolates appearing at certain time frames, indicating outbreaks due to local transmission of certain Typhi strains. CONCLUSIONS: The imported cases of typhoid fever from Southeast Asia were the major sources of indigenous S. Typhi infections in Taiwan. Small scale outbreaks occurred due to local transmission of the strains after their importation. PMID- 30300752 TI - A framework for linking resting-state chronnectome/genome features in schizophrenia: A pilot study. AB - Multimodal, imaging-genomics techniques offer a platform for understanding genetic influences on brain abnormalities in psychiatric disorders. Such approaches utilize the information available from both imaging and genomics data and identify their association. Particularly for complex disorders such as schizophrenia, the relationship between imaging and genomic features may be better understood by incorporating additional information provided by advanced multimodal modeling. In this study, we propose a novel framework to combine features corresponding to functional magnetic resonance imaging (functional) and single nucleotide polymorphism (SNP) data from 61 schizophrenia (SZ) patients and 87 healthy controls (HC). In particular, the features for the functional and genetic modalities include dynamic (i.e., time-varying) functional network connectivity (dFNC) features and the SNP data, respectively. The dFNC features are estimated from component time-courses, obtained using group independent component analysis (ICA), by computing sliding-window functional network connectivity, and then estimating subject specific states from this dFNC data using a k-means clustering approach. For each subject, both the functional (dFNC states) and SNP data are selected as features for a parallel ICA (pICA) based imaging-genomic framework. This analysis identified a significant association between a SNP component (defined by large clusters of functionally related SNPs statistically correlated with phenotype components) and time-varying or dFNC component (defined by clusters of related connectivity links among distant brain regions distributed across discrete dynamic states, and statistically correlated with genomic components) in schizophrenia. Importantly, the polygenetic risk score (PRS) for SZ (computed as a linearly weighted sum of the genotype profiles with weights derived from the odds ratios of the psychiatric genomics consortium (PGC)) was negatively correlated with the significant dFNC component, which were mostly present within a state that exhibited a lower occupancy rate in individuals with SZ compared with HC, hence identifying a potential dFNC imaging biomarker for schizophrenia. Taken together, the current findings provide preliminary evidence for a link between dFNC measures and genetic risk, suggesting the application of dFNC patterns as biomarkers in imaging genetic association study. PMID- 30300756 TI - Occurrence of intestinal parasites among asylum seekers in Italy: A cross sectional study. AB - BACKGROUND: In recent years Europe has experienced a dramatic increase in migration flows. Nevertheless, limited data is available about the occurrence of neglected parasitic diseases among migrant population. The purpose of the present study was to evaluate the prevalence of intestinal and urinary parasites in newly arrived asylum seekers. METHODS: A total of 364 newly arrived migrants hosted at the Asylum Seekers Centre of Castelnuovo di Porto (Italy) were screened during 8 months period for intestinal and urinary parasites. Each enrolled subject was interviewed using a standardized questionnaire, with focus on socio-demographical data and risk factors of parasitic infections. RESULTS: Stool analysis showed a prevalence of intestinal parasites of 20.6%. The travel route did not affect the prevalence of intestinal parasites (p = 0.096), while a significant negative correlation was found between the length of travel and the prevalence of parasite infection (p = 0.019). No statistically significant correlation between gastrointestinal symptoms and the presence of intestinal parasites was detected. CONCLUSION: The prevalence of intestinal parasitosis reported in asylum seekers does not necessarily reflect the prevalence of the parasitosis in the motherland. An anamnestic and syndromic approach may not be sufficient to highlight the problem of intestinal parasitic infestations in a screening setting.

AB - Elevation of Ca2+i and AMP-activated protein kinase (AMPK) are considered as major signals triggering transcriptomic changes in exercising skeletal muscle. Electrical pulse stimulation (EPS) of cultured myotubes is widely employed as an in vitro model of muscle contraction. This study examines the impact of Ca2+i mediated and Ca2+i-independent signaling in transcriptomic changes in EPS-treated C2C12 myotubes. Electrical pulse stimulation (40 V, 1 Hz, 10 ms, 2 h) resulted in [Ca2+]i oscillations, gain of Na+i, loss of K+i, and differential expression of 3215 transcripts. Additions of 10 MUM nicardipine abolished [Ca2+]i oscillations but did not affect elevation of the [Na+]i/[K+]i ratio seen in EPS-treated myotubes. Differential expression of 1018 transcripts was preserved in the presence of nicardipine, indicating a Ca2+i-independent mechanism of excitation transcription coupling. Among nicardipine-resistant transcripts, we noted 113 transcripts whose expression was also affected by partial Na+,K+-ATPase inhibition with 30 MUM ouabain providing the same elevation of the [Na+]i/[K+]i ratio as in EPS-treated cells. Electrical pulse stimulation increased phosphorylation of CREB, ATF-1, Akt, ERK, and p38 MAPK without any impact on phosphorylation of acetyl-CoA carboxylase and Unc-51 like autophagy activating kinase-1, i.e. downstream markers of AMPK activation. Unlike CREB, ATF-1, and MAPKs, an increment in Akt phosphorylation was abolished by nicardipine. Thus, our results show that Ca2+i-independent signaling plays a key role in altered expression of 30% of studied genes in EPS-treated myotubes. This signaling pathway is at least partially triggered by dissipation of transmembrane gradients of monovalent cations.

Four forms of MSV coat protein (CP) assemblages were isolated from infected plants: geminate capsids, T = 1 icosahedral capsids, pentamers and decamers of CPs. Sequential exposure of geminate capsids to increasing pH, from 4.8 to 7.2 was used to monitor capsid disassembly. The capsids remain intact at pH4.8, disassemble to decamers and pentamers by pH6.4 and aggregate by pH7.2. Similarly, high salt and divalent cations cause disassembly. The disassembly process was reversed in low pH and low salt, but resulted in empty (no DNA) single and geminate capsid assemblies. This is likely due to disruption of CP-DNA interactions under acidic conditions and suggests a mechanism of capsid assembly in which the genome is packaged into preformed empty capsids. The pH assay developed in this study provides a method for characterizing the conditions that are the determinants of geminivirus assembly and disassembly. PMID- 30300757 TI - Modulation of associative learning in the hippocampal-striatal circuit based on item-set similarity. AB - Mounting evidence suggests that the medial temporal lobe (MTL) and striatal learning systems support different forms of learning, which can be competitive or cooperative depending on task demands. We have previously shown how activity in these regions can be modulated in a conditional visuomotor associative learning task based on the consistency of response mappings or reward feedback (Mattfeld & Stark, 2015). Here, we examined the shift in learning towards the MTL and away from the striatum by placing strong demands on pattern separation, a process of orthogonalizing similar inputs into distinct representations. Mnemonically, pattern separation processes have been shown to rely heavily on processing in the hippocampus. Therefore, we predicted modulation of hippocampal activity by pattern separation demands, but no such modulation of striatal activity. Using a variant of the conditional visuomotor associative learning task that we have used previously, we presented participants with two blocked conditions: items with high and low perceptual overlap during functional magnetic resonance imaging (fMRI). As predicted, we observed learning-related activity in the hippocampus, which was greater in the high than the low overlap condition, particularly in the dentate gyrus. In contrast, the associative striatum also showed learning related activity, but it was not modulated by overlap condition. Using functional connectivity analyses, we showed that the correlation between the hippocampus and dentate gyrus with the associative striatum was differentially modulated by high vs. low overlap, suggesting that the coordination between these regions was affected when pattern separation demands were high. These findings contribute to a growing literature that suggests that the hippocampus and striatal network both contribute to the learning of arbitrary associations that are computationally distinct and can be altered by task demands.

AB - The effects of substance abuse on other family members are not fully established. We estimate the contribution of parental substance abuse on offspring psychiatric morbidity in late adolescence and early adulthood, with emphasis on the timing and persistency of exposure. We used a nationally representative 20% sample of Finnish families with children born in 1986-1996 (n = 136,604) followed up in 1986-2011. We identified parental substance abuse and offspring psychiatric morbidity from hospital discharge records, death records and medication registers. The effects of parental substance abuse at ages 0-4, 5-9 and 10-14 on psychiatric morbidity after age 15 were estimated using population averaged and sibling fixed effects models; the latter controlling for unobserved factors shared by siblings. Parental substance abuse at ages 0-14 was associated with almost 2-fold increase in offspring psychiatric morbidity (HR = 1.86, 95% CI 1.78 1.95). Adjustment for childhood parental education, income, social class and family type reduced these effects by about 50%, with some further attenuation after adjustment for time-varying offspring characteristics. In the sibling fixed effects models those exposed at 0-4 or 5-9 years had 20% (HR = 1.20, 95% CI 0.90 1.60) and 33% (HR = 1.33, 95% CI 1.01-1.74) excess morbidity respectively. Also in sibling models those with early exposure at ages 0-4 combined with repeated exposure in later childhood had about 80-90% higher psychiatric morbidity as compared to never exposed siblings (e.g. for those exposed throughout childhood HR = 1.81, 95% CI 1.01-3.25). Childhood exposure to parental substance abuse is strongly associated with subsequent psychiatric morbidity. Although these effects are to a large extent due to other characteristics shared within the parental home, repeated exposure to parental substance abuse is independently associated with later psychiatric morbidity. PMID- 30300761 TI - Unexpected death in ill old age: An analysis of disadvantaged dying in the English old population. AB - The literature on death expectation in ill old age is mostly medical. A social science standpoint (especially quantitative) is practically absent. However, whether families, social and healthcare services can anticipate, support and prepare for the deaths of ill old adults is not reducible to the biomedical paradigm. Yet it is critical for end of life care (EOLC) policy. This study's aim is to investigate relatives' perception of death as unexpected in relation to both disease-related and care-related factors. Using the English Longitudinal Study of Ageing End-of-life Interviews Wave 6 this paper draws on probit regression analysis of unexpected (vs. expected) death in ill adults aged 50+. Findings are interpreted considering the containment of sudden death and the trajectories of dying in ill old age. The latter display overall visible decline preceding death. On this basis, EOLC literature and policy evidence death's uncertain timing as much as death's certain emergence in the horizon of expectation. Therefore, unexpected death in ill old age was interpreted as a failure to acknowledge dying, rather than the impossibility of discerning its approach. Very old age, dementia diagnoses and supported care environments were found to shape unexpected death. PMID- 30300763 TI - Investigation of flow characteristics in the maxillary sinus where polypoid changes develop. AB - Flow behavior in the maxillary sinus where polypoid changes develop was investigated using computational fluid dynamics. A nasal cavity model was constructed, after performing a virtual polypectomy based on computed tomography images of a patient, using a computer-aided design software to artificially remove polypoid changes inside the maxillary sinus. Local flow characteristics in the maxillary sinus were examined for one full respiration period. The results showed that the epithelial surfaces where polypoid changes occur are located in the lower part of the maxillary sinus which contains a protruding zone of the sinus and are characterized by stagnation of air during the entire respiration period. Due to the geometric characteristics, a very slow recirculating motion was found to occur in the bulging area for approximately half of the respiration period as a result of interaction with a larger-scale, counter-rotating vortex filling the middle of the maxillary sinus. With a much smaller velocity inside the maxillary sinus compared to that typically found in the airway passage through the middle meatus, both wall shear and pressure changes were found to be vanishingly small along the epithelial surface of the maxillary sinus where polypoid changes were found. PMID- 30300762 TI - Before the here and now: What we can learn from variation in spatiotemporal patterns of changing heart disease mortality by age group, time period, and birth cohort. AB - One hypothesized explanation for the recent slowing of declines in heart disease death rates is the generational shift in the timing and accumulation of risk factors. However, directly testing this hypothesis requires historical age-group specific risk factor data that do not exist. Using national death records, we compared spatiotemporal patterns of heart disease death rates by age group, time period, and birth cohort to provide insight into possible drivers of trends. To do this, we calculated county-level percent change for five time periods (1973 1980, 1980-1990, 1990-2000, 2000-2010, 2010-2015) for four age groups (35-44, 45 54, 55-64, 65-74), resulting in eight birth cohorts for each decade from the 1900s through the 1970s. From 1973 through 1990, few counties experienced increased heart disease death rates. In 1990-2000, 49.0% of counties for ages 35 44 were increasing, while all other age groups continued to decrease. In 2000 2010, heart disease death rates for ages 45-54 increased in 30.4% of counties. In 2010-2015, all four age groups showed widespread increasing county-level heart disease death rates. Likewise, birth cohorts from the 1900s through the 1930s experienced consistently decreasing heart disease death rates in almost all counties. Similarly, with the exception of 2010-2015, most counties experienced decreases for the 1940s birth cohort. For birth cohorts in the 1950s, 1960s, and 1970s, increases were common and geographically widespread for all age groups and calendar years. This analysis revealed variation in trends across age groups and across counties. However, trends in heart disease death rates tended to be generally decreasing and increasing for early and late birth cohorts, respectively. These findings are consistent with the hypothesis that recent increases in heart disease mortality stem from the beginnings of the obesity and diabetes epidemics. However, the common geographic patterns within the earliest and latest time periods support the importance of place-based macro-level factors. PMID- 30300764 TI - Foot binding in a Ming dynasty cemetery near Xi'an, China. AB - This paper describes the morphology of the feet of a population of elite women from the Ming dynasty (1368-1644 CE) in Shaanxi province. This is a social stratum, time, and place in which foot binding was practiced. Among a group of 31 skeletons exhumed from the cemetery, eight were women with well-preserved foot bones. Macroscopic examination revealed that half these women (4/8) had clearly altered foot bones: the metatarsal bones, and the few observable phalanges, were gracile and small, while the tarsal bones exhibited a slight reduction in size but no dramatic change in morphology. The other half of the women (4/8) had apparently unmodified metatarsal bones. T-tests comparing linear measurements of the foot bones between the two groups revealed that metatarsal bones were the most affected by binding, and among the tarsal bones, the talar trochlea and calcaneal dimensions were most impacted. This small group of skeletons reveals that some elite women in Shaanxi apparently still did not practice foot binding in the late Ming dynasty, or practiced a much milder form of foot binding, and that there was considerable variation even among those who did practice it.

AB - Lymphedema is a condition characterized by localized fluid retention and tissue swelling caused by a compromised lymphatic system. To minimize fluid build-up and stimulate the flow of fluid through the lymphatic system, compression garments are usually applied to patients with lymphedema. There are few studies to report complications of compression garments to treat breast cancer-related lymphedema. To our knowledge, this is the first report of radial nerve compression neuropathy associated with wearing a compression garment to treat lymphedema. PMID- 30300766 TI - Venous Thromboembolism is Associated with Lack of Vitamin D Supplementation in Patients with Spinal Cord Injury and Low Vitamin D Levels. AB - BACKGROUND: The role of vitamin D (VitD) in the pathogenesis of venous thromboembolism (VTE) and prevalence of low VitD (LVitD) in spinal cord injury (SCI) has motivated VitD testing and supplementation. This is an exploratory study of data collected at a time before the routine clinical practice of VitD supplementation, allowing for evaluation of the natural history of LVitD levels in patients with SCI. OBJECTIVE: To determine if VitD supplementation in persons with SCI and LVitD levels is associated with decreased prevalence of VTE. DESIGN: Retrospective cohort study. SETTING: Rehabilitation Center at Level I Trauma Center. PARTICIPANTS: Patients with SCI admitted to acute inpatient rehabilitation (N=282). MAIN OUTCOME MEASURES: VTE prevalence in patients with LVitD levels, grouped by presence or absence of VitD supplementation. RESULTS: Of the acute inpatient SCI population, 80% (227/282) demonstrated VitD levels < 30 ng/mL (LVitD). Although the incidence of VTE was almost double in the LVitD group, 19% (43/227) of the patients in the LVitD group had VTE versus 9% (5/55) of patients with VitD levels > 30 ng/mL (Normal VitD, NVitD), it did not achieve statistical significance (P=.108, V=.104). When the role of VitD supplementation was analyzed, individuals in the LVitD group who received no VitD supplementation (LVitDSuppNegative) had a statistically significant higher incidence of VTE compared to the LVitD group with VitD supplementation (LVitDSuppPositive) (24% [42/178] versus 2% [1/49]) (P<.001, V=.226). In post-hoc exploratory analyses, the VTE rate of patients in the LVitDSuppNegative group was noted to be significantly higher than all other patient groups combined (P<.001, V=.229). A binary logistic regression model incorporating clinical covariates also showed this grouping to be significant. CONCLUSION: A significant association appears to exist between lack of VitD supplementation and VTE occurrence in persons with acute SCI and LVitD levels. PMID- 30300767 TI - The Effectiveness of Injected Corticosteroid Type, Dose, and Volume for the Treatment of Pain in Small- and Intermediate-size Joints: A Systematic Review. AB - OBJECTIVE: To systematically evaluate the scientific literature examining the efficacy of corticosteroid injections in small- and intermediate-size joints, specifically looking at the effect of corticosteroid type, dose, and volume on clinical outcomes (pain and/or function). TYPE: Systematic review LITERATURE SURVEY: Medline (PubMed)(r), Cochrane Central Register of Controlled Trial, and SportDiscus(r) databases were searched. METHODOLOGY: Inclusion criteria included adult patients enrolled in prospective studies evaluating pain- and/or function related improvements following a corticosteroid injection of a small- or intermediate-sized joint. SYNTHESIS: A total of 28 articles were included in the study, all including patients with osteoarthritis and/or rheumatoid arthritis. Only six studies contained level I evidence, and most studies were prospective case series without a control. Most studies used 10-20mg of corticosteroid for small joints and 20-40mg in intermediate joints; wrist joints were the only joint studied that directly compared doses - 20mg was noninferior to 40mg. Triamcinolone hexacetonide was found to be superior to methylprednisolone in the interphalangeal finger joints; no other joints compared steroid types. No studies evaluated the effect of volume on clinical outcomes. Most studies showed pain and/or functional improvements for weeks to months. CONCLUSIONS: Very few studies directly examine the effect of corticosteroid type, corticosteroid dose, or injectate volume on clinical outcomes for small- or intermediate-size joint arthralgia. Future studies are needed to better elucidate the most effective treatment protocols. LEVEL OF EVIDENCE: Level II, systematic review of cohort studies.

AB - This is a case of 52-year old deaf female who was referred to the electrodiagnostic (EDX) laboratory for evaluation of pain and parasthesias in the left upper limb. The EDX study was normal. However, ultrasound revealed tendinopathy of the palmaris longus tendon, manifested by increased hypoechogenecity, caliber, and tenderness to sonopalpation compared to the right side. To the authors' knowledge there are no reported cases of palmaris longus tendinopathy diagnosed with ultrasound. This case supports the use of point of care ultrasound to explore other possible causes of pathology in patients with parasthesias in the context of a normal EDX study. PMID- 30300769 TI - Could the biomarker levels in saliva help distinguish between healthy implants and implants with peri-implant disease? A systematic review. AB - BACKGROUND: The most accurate data help to minimize possible mistakes on a patient's evaluation, as more robust findings are necessary to establish a correct diagnosis, prognosis and, consequently, better treatment. PURPOSE: Could biomarker levels in the saliva help to distinguish between healthy implants and implants with peri-implant disease? MATERIALS AND METHODS: An electronic database search of Pubmed/MEDLINE, Web of Science, the Cochrane Library, OVID and Scielo was performed. The articles and abstracts identified were considered relevant if they compared cytokine levels in saliva from patients with healthy implants to those in saliva from patients with untreated peri-implantitis. RESULTS: Lower salivary levels of interleukin 1beta were found in healthy implants than in inflamed implants. A significantly positive correlation was found between the salivary levels of IL-6 and peri-implant inflammatory conditions. The salivary concentrations of total antioxidants, urate and ascorbate were higher in healthy implants than in inflamed implants. The data extracted from the 6 studies evaluated in this review revealed heterogeneity in relation to the clinical parameters assessed, implant restoration, bone loss and peri-implant disease definitions. CONCLUSIONS: There was no clear, developed basis for using any specific biomarker in a clinical setting to distinguish between healthy implants and those with peri implant disease. PMID- 30300770 TI - In situ effect of fluoride toothpaste supplemented with nano-sized sodium trimetaphosphate on enamel demineralization prevention and biofilm composition. AB - OBJECTIVE: To evaluate the effect of a fluoride toothpaste containing nano-sized sodium trimetaphosphate (TMPnano) on enamel demineralization in situ and composition of the biofilm. DESIGN: This crossover double-blind study consisted of four phases (seven days each) and 12 volunteers who wore oral appliances containing four enamel bovine blocks. The cariogenic challenge was performed by 30% sucrose solution (6x/day). The toothpaste treatments (3x/day) were as follows: no F/TMP/TMPnano (Placebo), 1100 ppm F (1100F), 1100F plus 3% micrometric or nano-sized TMP (1100F/TMP; 1100F/TMPnano). Percentage of surface hardness loss (%SH), and integrated loss of subsurface hardness (DeltaKHN), as well as enamel calcium (Ca), phosphorus (P), and fluoride (F) were determined. Moreover, biofilm formed on the blocks were analyzed for F, Ca, P, and insoluble extracellular polysaccharide (EPS) concentrations. Data were analyzed using one way ANOVA, repeated measures followed by Fisher LSD test (p < 0.001). RESULTS: 1100F/TMPnano promoted the lowest %SH and DeltaKHN among all groups (p < 0.001). Regarding the F concentrations in the enamel and in the biofilm, there were no significant differences between 1100 F and 1100 F/TMPnano, but significantly increased enamel Ca concentrations (p < 0.001). 1100F/TMPnano showed lower values of EPS concentration when compared with 1100F (~80%) (p < 0.001). CONCLUSION: 1100F/TMPnano promoted a greater protective effect against enamel demineralization and significantly affected the composition of biofilm formed in situ when compared to 1100F toothpaste. PMID- 30300772 TI - Fire safety enhancement of a highly efficient flame retardant poly(phenylphosphoryl phenylenediamine) in biodegradable poly(lactic acid). AB - Flame-retarded poly(lactic acid) (PLA) biodegradable materials are viewed as promising as sustainable alternatives to petroleum-based commodity polymers. A new highly efficient flame retardant, poly(phenylphosphoryl phenylenediamine) (PPDA), was synthesized by the condensation of phenylphosphoryl dichloride with p phenylenediamine and its structure was confirmed by 1H nulear magnetic resonance and Fourier-transform infrared spectroscopy. When 3 wt% PPDA was incorporated into PLA, the limited oxygen index increased from 20.0% of neat PLA to 25.5% and its UL-94 vertical burning testing achieved V-0 rating. Moreover, the total heat release and peak heat release rate values of PLA/3 wt% PPDA material were decreased from 109.1 MJ/m2 and 643.7 kW/m2 of PLA to 98.3 MJ/m2 and 570.0 kW/m2, respectively, and the fire performance index increased from 0.081 of PLA to 0.132 m2 s/kW. The high fire safety of PPDA in PLA is mainly attributed to the combined effects of the phosphorous-containing radical inhibition and inert gases and the barrier action of the formed char layer. The addition of less than 3 wt% PPDA has little influence on the tensile and impact properties of PLA. The flame retardant PLA blends have great application potential in electrical casing, automobile interiors and three-dimensional printing materials.

AB - Carbon oxidation has two stages, the first is the formation of surface oxides and the second is the gasification of the surface oxides to CO2. Calcium carbonate (CaCO3) was used to catalyze the gasification of the surface oxides. The catalytic effect of on graphite oxidation and its catalytic mechanism were studied by using thermogravimetric technique and in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). It was found that characteristic temperature (T50) of graphite oxidation with CaCO3 was 946 K, 113 K lower than that of graphite only. DRIFTS analysis results show that surface oxides (adsorbed CO2 and carbonate CO32-) were formed on the graphite surface at a temperature above 473 K, carbonate products on graphite surface disappeared when CaCO3 was present; formation of CO32- on CaCO3 surface was confirmed, this CO32- may be more easily gasified into gaseous CO2. The kinetic analysis results showed that CaCO3 promoted graphite oxidation has an activation energy of 74.3 kJ mol-1, far lower than that of graphite (148 kJ mol-1). PMID- 30300774 TI - Quantitative research on gas explosion inhibition by water mist. AB - Water mist as an effective explosion inhibitor has wide application prospect to prevent and reduce gas explosion hazard. The quantitative study of gas explosion inhibition with water mist provides the groundwork for the design of gas explosion suppression system. In this paper, the influence of the initial droplet sizes and spraying concentrations on explosion inhibition were numerically studied in a 2D numerical model. Under the initial spraying concentrations in the range of ~1.5 kg/m3, the inhibition effect of water mist on the explosion overpressure was not significant. The inhibition effect of water mist was mainly reflected in the suppression of the explosion flame temperature. When the initial droplet sizes were in the range of 50-150 MUm, the flame length was obviously reduced. But when the initial droplet sizes were less than 50 MUm or more than 150 MUm, the inhibition to reduce flame length begin to weaken. The results of this study provide the theoretical basis of the suppression technology for gas explosion. PMID- 30300775 TI - Adducts formed during protein digestion decreased the toxicity of five carbonyl compounds against Caco-2 cells. AB - Acrolein (ACR), glyoxal (GO), methylglyoxal (MGO), hydroxymethylfurfural (HMF), and malondialdehyde (MDA) are toxic contaminants for humans. This work aimed to investigate whether intake of proteins can mitigate their toxicity. Simulated gastrointestinal digestion of proteins from pork, chicken, milk powder and soy protein isolate eliminated amount of ACR, GO, MGO, HMF, and MDA. Among six amino acids, cysteine showed highest capacity for elimination of these toxic compounds through the formation of adducts; it reached the highest elimination capacity for GO, MGO, ACR, MDA, and HMF in 40 min at pH 2.0, and 20 min at pH 7.0. The formed adducts between cysteine and GO, MGO, or ACR showed much lower toxicity against Caco-2 cells. Incubation of the cells with 8 mM GO and MGO for 48 h decreased the cell viability to 16.1%, 16.9% respectively; while incubation of the same concentration of their adducts still kept the cell viability at 82.2% and 81.6% respectively. Cysteine showed much higher detoxifying capacity for ACR than GO and MGO, which can lower the toxicity of ACR toward Caco-2 cells by 80 times. PMID- 30300776 TI - A unique Pb-binding flagellin as an effective remediation tool for Pb contamination in aquatic environment. AB - Metal contaminants present persistent and deleterious threats to environmental ecosystems and human health. Microorganisms can rapidly develop protective mechanisms against metal toxicity, such as metallothionein production. The identification of biological factors related to these protective mechanisms is essential for effective metal remediation. This study presents a robust pathway to rapidly locate and characterize a Pb-binding flagellin in Serratia Se1998, which can bind Pb at a 16:1 Pb: protein ratio. A column gel electrophoresis system hyphenated with inductively coupled plasma mass spectrometry (ICP MS) was constructed to efficiently separate and identify Pb-binding proteins from the whole bacterial proteome. PCR and transgenic assays were used to elucidate the exact sequences and biological function of Pb-binding proteins and heterogeneous expression of Pb-binding flagellin in E. coli could significantly enhance Pb removal from aqueous solution by approximately 45%. This method provides a benchmark procedure to rapidly identify biological factors responsible for metal biosorption. Identification of this unique Pb-binding flagellin highlights that microorganisms can survive high metal stresses due to various complex biological pathways for metal detoxification and remediation. PMID- 30300777 TI - Visible light promoted degradation of gaseous volatile organic compounds catalyzed by Au supported layered double hydroxides: Influencing factors, kinetics and mechanism. AB - In this paper, factors of initial concentration, catalyst dosage, irradiation intensity, relative humidity and reaction temperature onto visible light gaseous o-xylene photodegradation by ZnCr layered double hydroxides (ZnCr-LDHs) and Au supported ZnCr-LDHs (Au/ZnCr-LDHs) were investigated. ZnCr-LDHs shows low removal efficiency for o-xylene photodegradation, while Au/ZnCr-LDHs exhibits both excellent photodegradation rate and high TOF values for o-xylene as well as other VOCs including benzene, o-xylene, m-xylene and p-xylene. The kinetic equation and activation energy were calculated for o-xylene photodegradation, which are [Formula: see text] and 21.85 kJ/mol for ZnCr-LDH [Formula: see text] and 12.84 kJ/mol for Au/ZnCr-LDHs. The obvious difference both in kinetic equation and activation energy suggests the reaction mechanism of ZnCr-LDHs and Au/ZnCr-LDHs should be very different. The active species inhabitation experiments show that the major drive of photocatalytic reaction for ZnCr-LDHs is hydroxyl radical, while for Au/ZnCr-LDHs it is the hole and hydroxide radical. It is also proved that the support of Au NPs onto LDHs would result in the transfer of photoexcited electrons from LDHs to Au NPs which results in the enhancement of photocatalytic property as well as photocatalytic mechanism change based on UV-vis, XPS, the contribution of different wavelength ranges of visible light onto photocatalytic efficiency and electrochemical tests.

AB - In this paper, we propose a method for removing phenols and p-nitrophenols (PNPs) from flowing aqueous solutions generated by atmospheric pressure plasma jets (APPJs). For analyzing the removal characteristics, multiple techniques were used, including flow speed analysis of the aerated solution, optical emission spectroscopy (OES), and liquid chromatography. In addition, the reaction kinetics of diffusion and activation control processes were evaluated using aerated fluid speed variation and the corresponding activation energy. From these results, the relative intensities of hydroxyl radicals produced by an APPJ in water were found to be stronger than those in air and to decrease with increasing flow speed. Furthermore, the reaction kinetics were found to be diffusion-controlled when the solution flow speed was low and activation-controlled under high solution flow speed. It was also found that the degradation efficiency was enhanced with increasing flow speed, which increased the discharge voltage and temperature of the solution and changed the initial pH value when TiO2/UV catalysis was used. From the complex relationship between the reactive species, fluid diffusion, and discharge parameters in wastewater described herein, it is anticipated that these findings will facilitate new approaches to both the design and optimization of discharge reactors intended for wastewater treatment. PMID- 30300779 TI - Time of day effects on the relationship between daily sleep and anxiety: An ecological momentary assessment approach. AB - Previous research has linked sleep disturbance to anxiety. However, evidence for this relation has been inconsistent, largely limited to retrospective reports that do not account for daily variability, and silent on when the association is most pronounced. Thus, the present study utilized ecological momentary assessment (EMA) to examine the effects of daily deviations in total sleep time (TST) and person-average TST on anxiety and whether these effects varied as a function of time of day in a sample of unselected adults (N = 138). Results indicate that the amount of TST on a given night, relative to personal average TST, negatively predicted anxiety, and this relation was significant in the morning and afternoon, but not evening. In contrast, person-average TST was unrelated to average anxiety. Relations between TST and anxiety did not differ across objective (e.g., actigraphy) and subjective (e.g., sleep diary) measures. Furthermore, the pattern of results remained the same when controlling for previous day's anxiety and were not bidirectional. These findings suggest that getting less sleep than is typical for the individual predicts subsequent anxiety, and this effect is particularly strong in the morning. Average sleep duration may be less important to the experience of anxiety than deviations from that average. These findings highlight the importance of EMA to examine how and when variability in sleep confers vulnerability for anxiety symptoms. PMID- 30300780 TI - Effect of UV irradiation on iodinated trihalomethane formation during post chloramination. AB - Ultraviolet (UV) irradiation has been widely used in drinking water treatment processes, but its influence on the formation of disinfection by-products (DBPs), especially the emerging iodinated trihalomethanes (I-THMs) during post chloramination remains unclear. This study evaluated the impact of low pressure (LP) UV treatment on the formation of I-THMs during post-chloramination through two pathways. The first pathway is through the transition of DOM structure and composition during UV-chloramination, resulting significant increase of I-THM formation with increasing UV dosage in different dissolved organic matter (DOM) containing water (49.7%-90.5% at 1160 mJ/cm2). With the application of excitation emission matrix-parallel factor analysis (EEM-PARAFAC), we found that I-THM formation in UV-chloraminated water correlated well with two ratios of three PARAFAC humic-like components (C3/C2 and C1/C2, R2 = 0.958-1.000), suggesting that the ratios of fluorescent components can be used as reliable indicators for I-THM formation. Moreover, the shift in these fluorescent components is crucial for I-THM formation during UV-chloramination. Another pathway for UV irradiation to affect I-THM formation during post-chloramination is through the transformation of iodine species. Large amounts of reactive iodine species (HOI/I2 and I3-) can be generated directly in the mixed iodine system by UV light, leading to the enhancement of iodine utilization factor (IUF) (up to 0.040) after post-chloramination. These results suggest that UV application to DOM-containing water may induce changes in organic precursors and iodine species so as to enhance I-THM formation during post-chloramination.

AB - The main processes contributing to elevated effluent suspended solids in the full scale aerobic granular sludge process were studied. The two processes found to be most important were (1) rising of sludge due to degasification of nitrogen gas (produced by denitrification) and (2) wash-out of particles that intrinsically do not settle such as certain fats and foams. A mathematical model was made to describe the process of degasification of nitrogen gas during the feeding phase in an AGS reactor. The process of rising sludge due to degasification could be limited by stripping out the nitrogen gas before starting the settling phase in the process cycle. The wash-out of scum particles could be reduced by introducing a vertical scum baffle in front of the effluent weir, similar to weirs in traditional clarifiers. A full-scale Nereda(r) reactor in the municipality of Utrecht, The Netherlands, was operated with a nitrogen stripping phase and scum baffles for 9 months at an average biomass concentration of 10 g L-1 and an average granulation grade of 84%. In this period the influent suspended solids concentration was 230+/-118mgL-1 and the concentration of effluent suspended solids was 7.8+/-3.8mgL-1. PMID- 30300782 TI - The role of surfactants in wastewater treatment: Impact, removal and future techniques: A critical review. AB - Wastewater treatment has an important responsibility to react to changing consumer and industrial produced wastes that pose environmental challenges. Surfactants are one of these emerging contaminants. They are of interest because of their increasingly ubiquitous domestic and industrial use and the difficulty their presence causes traditional treatment. In response to this developing area, this critical review considers research from a variety of technical backgrounds to provide an up to date overview of the impact of surfactants on the environment, health and their removal. This found major concerns about surfactants on the environment and on health being corroborated in the past five years. Current research into removal focuses on existing biological and chemical wastewater treatment optimisation. Despite improvements being found to traditional biological methods using chemical pre-treatments there is a clear lack of consensus regarding the ideal strategy. Drawbacks and potential solutions for a range of these technologies, including Fenton reaction and aerobic degradation, are discussed. In this field the authors recommend an improved diversity in surfactants used for the research and addressing of significant knowledge gaps. Novel methods, such as Carbon Nanotube (CNT) use are also discussed. These methods, while showing promising results, will require continual research effort to resolve present issues such as variable performance and environmental concerns. Larger scale work is also needed to validate the initial work done. Potential uses of surfactants to optimise wastewater treatment, such as Surfactant Modified Zeolites (SMZs), are also discussed. This review finds that surfactant removal from wastewater is a promising and challenging field that warrants further investigation.

AB - Ultraviolet (UV) disinfection is widely used to inactivate microorganisms prior to release of treated municipal wastewater. However, limited data are available for in situ inactivation of infectious enteric viruses by UV treatment at full scale. In this study, a total of 51 pre-UV and 50 post-UV samples were collected over a two-year period from two wastewater treatment plants (WWTPs) and analyzed for noroviruses, rotavirus, reovirus, sapovirus, astrovirus, enteroviruses, adenoviruses and JC virus. Both pre-UV and post-UV samples had relatively high concentrations of these viruses determined by qPCR. Infectious viruses were also observed in 98% of pre-UV samples and 76% of post-UV samples by cell culture, using either cytopathic effect (CPE) or integrated cell culture with qPCR (ICC qPCR). Reovirus was the most common virus detected by ICC-qPCR, present in 92% of pre-UV and 48% of post-UV samples. Infectious enterovirus and adenovirus were detected by ICC-qPCR in 33% and 31% of pre-UV samples, 14% and 20% of post-UV samples, respectively. Mean log10 reduction estimates for infectious reovirus was 1.2 and 1.8 log for the two WWTPs as assessed by ICC-qPCR, which was similar to the reduction of total infectious viruses (1.5 and 1.7 log) as assessed by CPE in cells culture. Overall, quantification of infectious reovirus appears to provide a useful index of enteric virus inactivation during wastewater treatment at full scale. To our knowledge, this is the first comprehensive study to assess UV inactivation of human enteric viruses at full-scale in WWTPs using both molecular and cell culture techniques, providing important information for quantitative microbial risk assessment of UV inactivation of human viruses in municipal wastewater. PMID- 30300784 TI - Non-activated peroxymonosulfate oxidation of sulfonamide antibiotics in water: Kinetics, mechanisms, and implications for water treatment. AB - Despite that sulfate radical-based activated peroxymonosulfate (PMS) oxidation processes (e.g., UV/PMS, Co2+/PMS, etc.) have been widely applied for decontamination, the direct oxidation of organic contaminants by PMS per se is less known. This contribution reports that certain contaminants, such as sulfonamides (SAs), are amendable to direct oxidation by PMS without activation. Using sulfamethoxazole (SMX) as a representative, kinetics and density functional theory (DFT)-based computational methods were applied to elucidate the underlying mechanisms and pathways through which SMX was transformed by direct PMS oxidation. High resolution mass spectrometry (HR-MS) coupled with high performance liquid chromatography (HPLC) analyses using authentic standards were adopted to qualifying and quantifying SMX transformation products. Our results reveal that nonradical oxidation of SMX by PMS was initiated by formation of a transition state complex between PMS molecule and amino functional group of SMX. Such reaction was assisted by two water molecules, which significantly reduced energy barrier. Direct PMS oxidation of SMX led to the formation of N4-hydroxyl sulfamethoxazole (N4-OH-SMX), 4-nitroso-sulfamethoxazole (4-NO-SMX), and 4-nitro sulfamethoxazole (4-NO2-SMX), sequentially. Implications of PMS oxidation with SAs to water treatment were further evaluated by investigating the effects of PMS dosage, pH, and natural water matrices. While PMS has a potential to transform a suite of SAs with similar structures (SMX, sulfisoxazole, sulfamethizole, sulfapyridine, sulfadiazine, and sulfachloropyridazine), the formation of potential hazardous nitroso- and nitro-byproducts should be scrutinized before this technology can be safely used for water and wastewater treatment. PMID- 30300785 TI - Removal of sulfonamide antibiotics and human metabolite by biochar and biochar/H2O2 in synthetic urine. AB - Source-separated urine has been increasingly regarded as a promising alternative waste-stream for effectively removing pharmaceuticals and human metabolites. This study investigated the removal of sulfonamide antibiotics, one category among the most frequently detected antibiotics in the environment, by biochar and biochar/H2O2 in synthetic urine matrix. The adsorption and degradation of four parent sulfonamide antibiotics, including sulfamethoxazole, sulfadiazine, sulfamethazine, sulfadimethoxine, and one human metabolite, N4-acetyl sulfamethoxazole (together referred as SAs) were investigated. Biochar derived from cotton straw was applied as adsorbent for SAs and catalyst for H2O2. Results showed that the adsorption of SAs was inhibited in urine compared with that in phosphate buffer solution. Bicarbonate in urine placed major influence. Langmuir isotherm model well described the adsorption process in both buffer and urine matrices. Adsorption and desorption rates were estimated by a kinetic model, which well fitted the removal of SAs from aqueous phase at various biochar doses. The adsorption of SAs on biochar was due to multiple forces, in which van der Waals forces and hydrophobicity played major roles in distinguishing the sorption behavior of different SAs. To destruct the SAs, H2O2 was added with biochar. Except for N4-acetyl-sulfamethoxazole, all the parent SAs can be degraded in urine matrix. Carbonate radical, produced from the activation of peroxymonocarbonate by biochar, was proposed to be the major contributing reactive species in biochar/H2O2 system in urine matrix. PMID- 30300786 TI - The evaluation of Oryza sativa L (Black rice) extracts for detection of spermatozoa on the clothing and vaginal swab samples. AB - Investigation of sexual assault cases from the evidence involving vaginal swab, clothing and others is examined by a forensic scientist. The explanation of trace findings on spermatozoa on clothing is often problematic due to the use of different staining methods. Conventional staining method used either Papanicolaou (PAP) or Dip quick(r) stain as synthetic dyes which are expensive imported material and harmful to human health. Therefore, the present study aims to determine the ability of Oryza sativa L (black rice) extract as a natural dye to detect spermatozoa on the clothing and vaginal swab casework samples for routine forensic examination. Results revealed that black rice extract has a highly effective for detecting spermatozoa on cloth and vaginal swab casework samples. There was no significantly different in the detection of spermatozoa compared with rapid PAP stain and Dip quick(r) stain. Results also showed that the staining of vaginal swab casework with black rice extracted can be used for PCR amplification of centromeric alphoid repeat gene on chromosome Y for 60 days. Moreover, the DNA extracted from stained semen slide generates a full profile of 16 alleles of STR typing. The results indicate that a new natural staining dye which extracted from black rice can be used to detect spermatozoa and identify a person from the trace evidence. The application of natural dyes for routine staining of spermatozoa from forensic specimens will decrease the expense to be spent in purchasing the synthetic dye and reduce their side effects on human and environment. PMID- 30300787 TI - Recognition, treatment, and sequelae of congenital cytomegalovirus in Australia: An observational study. AB - BACKGROUND AND OBJECTIVES: Australian national surveillance data was used to assess recognition, sequelae, and antiviral therapy for congenital cytomegalovirus (CMV) cases. STUDY DESIGN: Data from congenital CMV cases reported through the Australian Paediatric Surveillance Unit born January 1999 to December 2016 were described and Chi-square tests used to characterise trends and associations in case reporting, maternal CMV serology testing, and antiviral therapy. Descriptive analyses for hearing loss and developmental delay were reported for cases born >=2004, following introduction of universal neonatal hearing screening. RESULTS: There were 302 congenital CMV cases (214 symptomatic, 88 asymptomatic). Congenital CMV was suspected in 70.6% by 30 days of age, with no differences across birth cohorts. Maternal CMV serology testing was associated with maternal illness during pregnancy but not birth cohort. There was increasing antiviral use for symptomatic cases, being used in 14% born 1999-2004, 19.6% born 2005-2010, and 44.4% born 2011-2016 (p < 0.001). For those born >=2004, hearing loss was reported in 42.1% of symptomatic and 26.6% of asymptomatic cases; while developmental delay was reported in 16.9% of symptomatic and 1.3% of asymptomatic cases. CONCLUSION: There appears to be under-reporting and under-recognition of congenital CMV despite increasing use of antiviral therapy. Universal newborn CMV screening should be considered to facilitate follow-up of affected children and targeted linkage into hearing and developmental services, and to provide population-level infant CMV epidemiology to support research and evaluation of antiviral and adjunctive therapies. PMID- 30300788 TI - CTRP5 promotes transcytosis and oxidative modification of low-density lipoprotein and the development of atherosclerosis. AB - BACKGROUND AND AIMS: Increased transcytosis of low-density lipoprotein (LDL) across the endothelium and oxidation of LDL deposited within the subendothelial space are crucial early events in atherogenesis. C1q/TNF-related protein (CTRP) 5 is a novel secreted glycoprotein and its biological functions are largely undefined. METHODS: Expression of CTRP5 was analyzed in sera and atherosclerotic plaques of patients with coronary artery disease (CAD). The role of CTRP5 in atherogenesis was investigated in vitro and in vivo. RESULTS: We found CTRP5 serum levels were higher in patients with than without CAD (247.26 +/- 61.71 vs. 167.81 +/- 68.08 ng/mL, p < 0.001), and were positively correlated with the number of diseased vessels (Spearman's r = 0.611, p < 0.001). Increased expression of CTRP5 was detected in human coronary endarterectomy specimens as compared to non-atherosclerotic arteries. Immunofluorescence further showed that CTRP5 was predominantly localized in the endothelium, infiltrated macrophages and smooth muscle cells in the neointima. In vivo and in vitro experiments demonstrated that CTRP5 promoted transcytosis of LDL across endothelial monolayers, as well as the oxidative modification of LDL in endothelial cells. Mechanistically, we found that CTRP5 up-regulated 12/15-lipoxygenase (LOX), a key enzyme in mediating LDL trafficking and oxidation, through STAT6 signaling. Genetic or pharmacological inhibition of 12/15-LOX dramatically attenuated the deposition of oxidized LDL in the subendothelial space and the development of atherosclerosis. CONCLUSIONS: These data indicate that CTRP5 is a novel pro atherogenic cytokine and promotes transcytosis and oxidation of LDL in endothelial cells via up-regulation of 12/15-LOX. PMID- 30300789 TI - Trans-anal minimally invasive surgery: A new technique to avoid peritoneal entry. AB - INTRODUCTION: Transanal minimally invasive surgery (TAMIS) is a valuable surgical option for removal of rectal polyps and early rectal cancers. A potential complication of this technique is abdominal entry if the lesion is located above the peritoneal reflection. We present the first case series describing the use of a laparoscopic stapling device to remove a sessile lesion, and seal the resulting defect simultaneously with full thickness excision of the rectal lesion, avoiding abdominal entry. PRESENTATION OF CASES: Five patients with rectal lesions between 8 and 14 cm from the anal verge are described in this case series. Each underwent a stapled-TAMIS procedure as the lesion was suspected to be above the peritoneal reflection. The goal specimen was achieved in each procedure. DISCUSSION: This article demonstrates the feasibility of a novel technique to remove sessile polyps in the upper rectum using laparoscopic staplers trans-anally through the TAMIS port. More studies and long-term follow-up are needed to evaluate the oncologic outcomes including the recurrence rate for those lesions removed with a stapler. CONCLUSION: For rectal lesions suspected to be above the peritoneal reflection, a stapled resection through a TAMIS port could prove be a valuable addition to the standard excisional approach to TAMIS. PMID- 30300790 TI - A rare case of paraganglioma of the cystic duct. AB - INTRODUCTION: Biliary system paragangliomas are rare neuroendocrine tumors of embryonic neural crest origin. The majority is asymptomatic and incidentally found due to gallbladder functional disorders. Herein, we present a non functional, 2.25 mm focus in the cystic duct, which to our knowledge, is the first reported paraganglioma of the cystic duct. PRESENTATION OF CASE: The patient presented to the Emergency Department complaining of a sudden-onset, right upper abdominal and epigastric pain. Ultrasound and Computed Tomography were both consistent with signs of early cholecystitis. Laparoscopic cholecystectomy was performed without major complications. In addition to cholelithiasis and chronic cholecystitis, pathological examination reported a neuroendocrine proliferation in the cystic duct measuring 2.25 mm favoring paraganglioma. Incidentally, the patient is unique in that they were also found to have an adrenal nodule and a normocalcemic primary hyperparathyroidism that raised suspicion for an underlying endocrinopathy. Nevertheless, genetic testing was negative. DISCUSSION: Extensive literature review demonstrates only nine cases of gallbladder paraganglioma, and three cases of hepatic ducts paraganglioma, but no cases of paraganglioma occurring at the cystic duct. Although a gene mutation and syndrome was not identified in the patient, the fact that an adrenal nodule and normocalcemic primary hyperparathyroidism were present, suggests that a complete hormonal workup should be obtained in these patients. CONCLUSION: It is important to realize that biliary system paragangliomas, although rare, may occur. As they have an association with multiple endocrine neoplasia syndrome, a thorough endocrine investigation should be made. PMID- 30300791 TI - A case report of a rare, spontaneous external jugular vein aneurysm. AB - INTRODUCTION: Compared to arterial aneurysms, venous pseudoaneurysms are rare and even more rare are external jugular vein aneurysms (EJV). To our knowledge, there are less than 10 well-documented cases of EJV aneurysms accessible. PRESENTATION OF CASE: Our patient is a 75 year old hispanic female who noticed a painless right neck mass two months prior. Ultrasound confirmed a cystic mass of unknown etiology containing doppler flow. Excisional biopsy revealed an EJV aneurysm with pathologic results of: blood, calcified debris, and a vessel wall consistent with EJV pseudoaneurysm. DISCUSSION: EJV aneurysms are clinically rare compared to IJV aneurysms. Recent trauma, cardiovascular disease and age are reported to be the highest significant clinical risk factors in the formation of jugular vein aneurism (JVA). The absence of trauma in our patient is noteworthy because it eliminates a direct contributor to a normally low-pressure vessel. CONCLUSIONS: Despite their rarity, spontaneous EJV aneurisms should be included in the differential of the elderly hypertensive patient who is presenting with a painless mass of the lateral neck that has cystic appearance and ultrasound findings of doppler flow. PMID- 30300792 TI - Effect of chitosan, and bacteriocin - Producing Carnobacterium maltaromaticum on survival of Escherichia coli and Salmonella Typhimurium on beef. AB - The aim of this study was to investigate the synergistic effect of chitosan and bacteriocins against Escherichia coli and Salmonella in media and in lean beef. The inhibitory effects of chitosan and bacteriocins against E. coli AW1.7 and S. enterica Typhimurium in media were determined by a critical dilution assay. The efficacy a bacteriocin-producing strain of Carnobacterium maltaromaticum and high molecular weight chitosan (HMWC) in inactivation of E. coli AW1.7 and S. Typhimurium was evaluated on beef. Current interventions applied in the beef industry, steaming coupled with lactic acid, were used as reference. HMWC demonstrated higher antibacterial activity than water soluble chitosan (WSC) or chitosan oligosaccharides (COS) in media, and the addition of partially purified bacteriocins from C. maltaromaticum UAL307 increased the activity of the chitosan in vitro. The hurdle combinations associated with HMWC inactivated E. coli AW1.7 and S. enterica Typhimurium more effectively on lean beef when compared to steam or steam coupled with lactic acid. When used on beef, addition of bacteriocins and chitosan did not increase the antibacterial efficacy. Cell counts of S. enterica were further reduced during storage in presence of C. maltaromaticum and chitosan; however, this decrease was not dependent on bacteriocin production. In conclusion, addition of chitosan alone or in combination with C. maltaromaticum UAL 307 as protective culture significantly reduces cell counts of E. coli and Salmonella on beef. Results will be useful to improve pathogen intervention treatments in beef processing. PMID- 30300793 TI - Gene sequence screening for manganese poisoning-susceptible genes and analysis of gene interaction effects. AB - Manganese poisoning is a common occupational disease, studies have found that the susceptibility to manganese poisoning differs in individuals. We adopted genome wide sequencing methods to screen for susceptibility genes involved in gene mediated metabolic pathways from the perspective of manganese poisoning. We identified 18,439 genes in this study, including 14,272 known genes and 4398 new genes. We then selected 17 differential genes using p values, of which 7 genes were down-regulated and 10 genes were up-regulated. Possible interaction genes for each differential gene were selected according to the String database. Sgk1, HCRTr1, HspB1, Rem2, Oprd1, ATF5, and TRHr identified in this study may be involved in oxidative stress mechanisms, dopamine (DA) synthesis, and neuronal survival during apoptosis and may affect susceptibility to manganese poisoning. PMID- 30300794 TI - Dietary co-exposure to methylmercury and monosodium glutamate disrupts cellular and behavioral responses in the lobster cockroach, Nauphoeta cinerea model. AB - The present study aims to investigate the effect of monosodium glutamate (MSG) both separately and combined with a low dose of methylmercury (MeHg) on behavioral and biochemical parameters in Nauphoeta cinerea (lobster cockroach). Cockroaches were fed with the basal diet alone, basal diet + 2% NaCl, basal diet + 2% MSG; basal diet + 0.125 mg/g MeHg, basal diet + 0.125 mg/g MeHg + 2% NaCl; and basal diet + 0.125 mg/g MeHg + 2% MSG for 21 days. Behavioral parameters such as distance traveled, immobility and turn angle were automatically measured using ANY-maze video tracking software (Stoelting, CO, USA). Biochemical end-points such as acetylcholinesterase (AChE), glutathione-S-transferase (GST), total thiol and TBARS were also evaluated. Results show that MeHg + NaCl, increased distance traveled while MeHg + MSG increased time immobile. AChE activity was significantly reduced in cockroaches across all the groups when compared to the control. There was no significant alteration in GST activity and total thiol levels. It could be that both NaCl and MSG potentiates the neurotoxic effect of MeHg in cockroaches. PMID- 30300795 TI - Road safety and distraction, results from a responsibility case-control study among a sample of road users interviewed at the emergency room. AB - Despite the complexities of the driving task, more and more drivers engage in non driving secondary tasks that take their hands (manual distraction), their eyes (visual distraction) and/or their mind (cognitive distraction) away from their primary task. Inattention arising from external distractions has received much less consideration beyond the impact of mobile phone use. We aimed to investigate the association between distraction behind the wheel and risk of being responsible for a road traffic crash in a responsibility case-control study. The study population included 1912 drivers injured in a road traffic crash recruited in two rounds of recruitment (from April 2010 to August 2011 and from March 2013 to January 2015) in the adult emergency department of Bordeaux University Hospital (France). Responsibility levels were estimated using a standardized method. Self-reported activities among a pre-established list of potential distractions were combined into four external distraction variables: visual distraction, manual distraction, auditory distraction, and verbal interaction. A significantly increased risk of being responsible for a road traffic crash was associated with the exposure to activities that take drivers' eyes off the road (adjusted odds ratio 2.99, 95% confidence interval 1.42-6.28) and activities that take drivers' hands off the wheel (adjusted odds ratio 2.12, 95% confidence interval 1.20-3.75). No significant associations were found for verbal interaction and listening to the radio and/or singing. This study suggests that beyond the use of mobile phone, particular attention must be paid to activities that involve visual and/or manual distraction. PMID- 30300796 TI - Reducing intercity bus crashes through driver rescheduling. AB - Intercity bus crashes often involve driver fatigue, which itself is usually the result of sleep deprivation, long driving hours, a maladjusted circadian rhythm, or some combination of the above. And driver scheduling has long been suspected as the root cause affecting sleepiness and fatigue. As such, a fundamental question for intercity bus carriers is how to reduce crashes associated with driver schedules, while maintaining a nonstop service? This research seeks to develop a paradigm to minimize overall fleet crash risk by rescheduling. In this study, we first identified those driving schedules associated with the highest crash risks, and a rescheduling scheme is then proposed to reduce fleet crashes overall. A case-study approach was employed to identify driver scheduling associated with higher crash risk, and a mathematical program was then formulated to minimize fleet crash risk. Our results showed that several types of driver schedules would lead to higher crash risk; for example: (1) working in the afternoon or early hours in the morning for two consecutive days; and (2) commencing a driving shift in the mornings, the afternoon or the early hours of the morning after being off-duty for more than 24 h. To meet the challenge of maintaining a nonstop service while simultaneously minimizing the crash risk associated with these risk patterns, a mathematical program was developed, and it was found that rescheduling based on our algorithm could reduce the incidence of crashes by approximately 30 percent. PMID- 30300797 TI - Who is responsible for global road safety? A cross-cultural comparison of Actor Maps. AB - The traditional three 'E's approach to road safety (engineering, education, enforcement) has had, and will continue to have, a significant impact on road traffic casualty rates worldwide. Nevertheless, with rising motorisation in many countries, global fatality numbers have changed little over the past decade. Following calls for the application of sociotechnical systems thinking to the problem, we widen the road safety discussion with an additional four 'E's; economics, emergency response, enablement, and, the umbrella term for the approach taken, ergonomics. The research presents an application of Rasmussen's Risk Management Framework to the road safety systems of five distinct nations; Bangladesh, China, Kenya, the UK, and Vietnam. Following site visits, reviews of literature, and interviews with subject matter experts in each of the countries, a series of Actor Map models of the countries' road safety systems were developed. These are compared and discussed in terms of the wide variety of interconnecting organisations involved, their influences on road safety outcomes, the differences between nations, and the need to look beyond road users when designing road safety interventions. PMID- 30300799 TI - Harm perceptions of electronic cigarettes and nicotine: A nationally representative cross-sectional survey of young people in Great Britain. AB - BACKGROUND: E-cigarettes often contain nicotine without the most harmful constituents of tobacco smoke. AIMS: This study aims to assess prevalence and correlates of accurately perceiving e-cigarettes as less harmful than cigarettes and that none or a small amount of the harm from smoking comes from nicotine. METHODS: Cross-sectional survey of 2,103 11-18-year-olds in Great Britain in 2016. Prevalence of e-cigarette and nicotine harm perceptions were calculated. Logistic regressions assessed associations between accurate e-cigarette and nicotine harm perceptions and smoking, e-cigarette use, gender, age, region, social grade, family smoking, family e-cigarette use, smoking friends, public approval of smoking, and public approval of e-cigarettes. Associations between accurate e-cigarette and nicotine harm perceptions were also assessed. RESULTS: Most (63.4%) accurate e-cigarette harm perceptions were higher among those aged 16+ (OR = 1.89 [95%CI = 1.45-2.47]), 14-15 (OR = 1.29 [1.00-1.65]), who tried/used an e-cigarette sometimes (OR = 1.51 [1.03-2.21]), with family e cigarette use (OR = 2.11 [1.46-3.04]), who perceived public disapproval of smoking (OR = 2.11 [1.18-3.77]) and approval of e-cigarettes (OR = 2.44 [1.73 3.45]), and with accurate nicotine harm perceptions (OR = 2.05 [1.28-3.28]). Accurate nicotine harm perceptions were higher among those aged 16+ (OR = 2.60 [1.62-4.16]), from North England (OR = 1.87 [1.02-3.43]) and Wales/Scotland (OR = 2.61 [1.35-5.03]) vs. London, with family smoking (OR = 1.59 [1.05-2.42]), and with accurate e-cigarette harm perceptions (OR = 2.12 [1.32-3.41]). CONCLUSIONS: Many young people have inaccurate harm perceptions of e-cigarettes and nicotine. Accurate e-cigarette and nicotine harm perceptions were associated with one another. E-cigarette use was associated with accurate e-cigarette but not nicotine harm perceptions; smoking was not associated with either. PMID- 30300798 TI - Using single cell analysis for translational studies in immune mediated diseases: Opportunities and challenges. AB - The difficulty of studying small tissue samples and rare cell populations have been some of the main limitations in performing efficient translational studies of immune mediated diseases. Many of these conditions are grouped under the name of a single disease whilst there are strong suggestions that disease heterogeneity leads to variable disease progression as well as therapeutic responses. The recent development of single cell techniques, such as single cell RNA sequencing, gene expression profiling, or multiparametric cytometry, is likely to be a turning point. Single cell approaches provide researchers the opportunity to finally dissect disease pathology at a level that will allow mechanistic classifications and precision therapeutic strategies. In this review, we will give an overview of the current and developing repertoire of single cell techniques, the benefits and limitations of each, and provide an example of how single cell techniques can be utilized to understand complex immune mediated diseases and their translation from mouse to human. PMID- 30300801 TI - Non-medical use of prescription drugs and cultural orientation among college students in China. AB - BACKGROUND: Due to a dramatic increase in the past 20 years, the non-medical use of prescription drugs (NMUPD) has become a global public health issue. College students have high prevalence of NMUPD in the United States. However, limited studies have been conducted among Chinese students. The purposes of this study were to examine the prevalence of NMUPD among college students in two urban centers (Beijing and Macau) in China and assess its relationships with cultural orientation (collectivism - primary focus on the group and individualism - primary focus on the individual). METHODS: In January-April 2017, 849 undergraduates (72.2% female) from Beijing and Macau, with an average age of 20 completed online surveys about their demographics, NMUPD, and cultural orientation. RESULTS: Overall, 62.9% (lifetime) and 33.4% (past three-months) of students in Beijing reported NMUPD, while 35.9% (lifetime) and 21.8% (past three months) of students in Macau reported NMUPD. The most commonly non-medically used class of medicine (lifetime) was analgesics (62.9% Beijing; 35.5% Macau), followed by sedatives (4.0% Beijing; 0.9% Macau), anxiolytics (2.7% Beijing; 0.6% Macau), and stimulants (1.0% Beijing; 0.2% Macau). Multivariate analyses suggested a positive association of individualism with lifetime NMUPD (OR = 1.78, 95% CI = 1.15, 2.75, p < .01 in Beijing; OR = 1.53, 95% CI = 1.16, 2.02, p < .01 in Macau). CONCLUSION: NMUPD in Chinese college students appears to be common. More discussion is needed in China about regulation of prescription drugs. Future culturally-tailored NMUPD-risk reduction intervention programs may be beneficial to Chinese college students. PMID- 30300800 TI - Accounting for the uncounted: Physical and affective distress in individuals dropping out of oral naltrexone treatment for opioid use disorder. AB - BACKGROUND: The theoretical benefits of naltrexone as a treatment for opioid use disorder (e.g., safety, non-addictive, low risk of diversion) stand in sharp contrast to its disappointing record on retention in most samples. The relationship of uncomfortable physical and dysphoric symptoms to retention on naltrexone is a controversial and under-studied issue. METHODS: Using data from a randomized controlled trial of voucher-based contingency management and support from a significant other to enhance retention on oral naltrexone, we compared self-reported somatic and dysphoric symptoms, measured weekly, for individuals who were retained on naltrexone through the 12-week trial (n = 50) versus those who dropped out (n = 70). RESULTS: There were no differences between participants who completed treatment and those who dropped out on multiple baseline characteristics, including somatic or affective symptoms prior to treatment. However, whether analyzed cross-sectionally or over time, participants who dropped out consistently reported higher rates of somatic symptoms, particularly difficulty sleeping, as well as affective symptoms, including multiple indicators of depression, anxiety, and anhedonia. CONCLUSIONS: Although the smaller group of participants who were retained on oral naltrexone for 12 weeks reported decreasing physical and affective discomfort over time, there was substantial evidence that those who dropped out experienced continued and significant levels of distress. Individuals who report physical or affective distress while taking naltrexone may be at higher risk of dropout. PMID- 30300802 TI - Cigarette smoking is associated with cortical thinning in anterior frontal regions, insula and regions showing atrophy in early Alzheimer's Disease. AB - BACKGROUND: Magnetic resonance imaging studies of cigarette smoking-related effects on human brain structure primarily focused on cortical volumes. Much less is known about the effects of smoking on cortical thickness. Smokers and Non smokers were compared on regional cortical thickness. We predicted smokers would demonstrate greater age-related thinning localized to anterior frontal regions that serve as nodes for the executive, salience, and emotional regulation networks (ESER regions) and those demonstrating significant atrophy in early Alzheimer's Disease (AD regions). METHODS: Non-smokers (n = 41) and smokers (n = 41), 22-70 years of age, completed a 4 T MRI study. Regional cortical thickness was quantitated via FreeSurfer. In smokers, associations between smoking severity, decision-making, impulsivity, and regional cortical thickness were examined. RESULTS: Smokers demonstrated cortical thinning in the medial and lateral OFC, insula, entorhinal, fusiform, middle temporal, and Composite AD regions. In Smokers, greater pack-years were associated with thinner lateral OFC, middle temporal, inferior parietal, fusiform, precuneus, and Composite AD regions. In Smokers, poorer decision-making/greater risk taking was related to thinner cortices in caudal ACC, rostral middle frontal and superior frontal gyri, and Composite ESER. Higher self-reported impulsivity was associated with thinner rostral and caudal ACC. CONCLUSIONS: This study provides additional evidence that cigarette smoking is associated with thinner cortices in regions implicated in the development and maintenance of substance use disorders and in regions demonstrating significant atrophy in early AD. The novel structure-function relationships in Smokers further our understanding of the neurobiological substrates potentially underlying the neuropsychological abnormalities documented in smokers. PMID- 30300803 TI - Assessment of rimonabant-like adverse effects of purported CB1R neutral antagonist / CB2R agonist aminoalkylindole derivatives in mice. AB - BACKGROUND: Cannabinoids may be useful in the treatment of CNS disorders including drug abuse and addiction, where both CB1R antagonists / inverse agonists and CB2R agonists have shown preclinical efficacy. TV-5-249 and TV-6-41, two novel aminoalkylindoles with dual action as neutral CB1R antagonists and CB2R agonists, previously attenuated abuse-related effects of ethanol in mice. PURPOSE: To further characterize these drugs, TV-5-249 and TV-6-41 were compared with the CB1R antagonist / inverse agonist rimonabant in assays relevant to adverse effects and cannabinoid withdrawal. PROCEDURES AND FINDINGS: The cannabinoid tetrad confirmed that TV-5-249 and TV-6-41 were devoid of CB1R agonist effects at behaviorally-relevant doses, and neither of the novel drugs induced rimonabant-like scratching. Generalized aversive effects were assessed, and rimonabant and TV-5-249 induced taste aversion, but TV-6-41 did not. Schedule controlled responding and observation of somatic signs were used to assess withdrawal-like effects precipitated by rimonabant or TV-6-41 in mice previously treated with the high-efficacy CB1R agonist JWH-018 or vehicle. Rimonabant and TV 6-41 dose-dependently suppressed response rates in all subjects, but TV-6-41 did so more potently in JWH-018-treated mice than in vehicle-treated mice, while rimonabant equally suppressed responding in both groups. Importantly, rimonabant elicited dramatic withdrawal signs, but TV-6-41 did not. CONCLUSIONS: These findings suggest differences in both direct adverse effects and withdrawal related effects elicited by rimonabant, TV-5-249, and TV-6-41, which could relate to neutral CB1R antagonism, CB2R agonism, or a combination of both. Both mechanisms should be explored and exploited in future drug design efforts to develop pharmacotherapies for drug dependence. PMID- 30300804 TI - Association between the splice mutation g.8283C>A of the PHKG1 gene and meat quality traits in Large White pigs. AB - Pork technological and sensory qualities are greatly affected by water-holding capacity (WHC), pH, color, tenderness, and chemical composition, and the identification of genetic markers affecting these traits is regarded as a primary goal in pig selection. Phosphorylase Kinase Catalytic Subunit Gamma 1 (PHKG1) gene has been reported in the literature to be a candidate gene for meat drip loss, ultimate pH, color and glycolytic potential. This study was mainly aimed at testing whether PHKG1 g.8283C>A SNP was associated with meat quality traits in heavy pigs. The associations between PHKG1 g.8283C>A SNP, WHC, meat color and pH measurements were evaluated in 250 Italian Large White pigs. The marker showed an additive effect on WHC (P = .008) and a dominant effect on a* color parameter (P = .004). Further studies are needed to elucidate the effects of this polymorphism on heavy pig meat quality traits before this mutation could be considered a marker of interest for heavy pig selection schemes. PMID- 30300805 TI - Balance highly influences flexibility measured by the toe-touch test. AB - Flexibility evaluation is a standard assessment in clinical and in sports settings. The Toe-touch test (TTT) is a common assessment tool to evaluate posterior muscular chain flexibility, but the test procedure implies a balance demand. The objective of the study was to verify the hypothesis that the balance demand during the TTT may affect the flexibility measured by the test. Twenty healthy, active young adults participated in the present study. Toe-touch test outcome (the linear finger to toe distance), Center of Pressure (CP) and sagittal plane joint angles were compared under two balance conditions: (1) standard TTT (ST) and (2) minimised postural demand (MPD) during TTT (using a device that restrained the participant against a forward fall). Then, ST was re-tested to verify a possible effect of motor learning on TTT outcome. Compared to ST, MPD showed an improvement of 73% in test outcome, greater flexion of the ankle, greater total body flexion, and a forward displacement of the CP. Re-test of ST showed indications of motor learning with a different balance strategy compared to the first trial in the same condition. The test outcome showed significant negative correlations with CP position in ST (weak correlation), in the re-test (strong correlation) and when the conditions were combined (moderate correlation). In conclusion, TTT outcome was highly affected by balance performance. Maximum range of motion during ST was a fraction of the range obtained when balance demand was minimized. PMID- 30300806 TI - Removal of micropollutants and cyanobacteria from drinking water using KMnO4 pre oxidation coupled with bioaugmentation. AB - Increasing micropollutant and cyanobacterial contamination of drinking water threatens human health worldwide. However, these contaminates are not efficiently removed by common drinking water treatment processes, and thus additional treatments are frequently required. Recent investigations have demonstrated that KMnO4 pre-oxidation can efficiently remove some micropollutants and cyanobacteria but the release of cyanobacterial toxins and Mn2+ limit its use. To overcome these problems, we proposed a KMnO4 pre-oxidation coupled with bioaugmentation (e.g., sand filtration) method to treat micropollutant- and cyanobacteria-laden water. We used 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid (BP-4, a common micropollutant in drinking water sources) and Microcystis aeruginosa (a widely distributed cyanobacterial species) as model pollutants to verify the feasibility of the proposed method. Results revealed that KMnO4 pre-oxidation efficiently removed existing natural organic matter and Microcystis aeruginosa but failed to remove BP-4 and released Mn2+ and microcystin-LR (MC-LR) during treatment. Following the addition of a manganese-oxidizing bacterial strain (Pseudomonas sp. QJX-1) to the KMnO4-treated solution, we found that the bacteria could transform Mn2+ to Mn(III&IV) oxides, with the formed Mn oxides then able to remove BP-4 and MC-LR. Overall, the proposed method exhibited advantages in the removal of natural organic matter (i.e., decreasing disinfection byproduct formation), micropollutants, and cyanobacteria as well as preventing the release of Mn2+, and thus may be considered a good alternative for treating polluted drinking water. PMID- 30300807 TI - Mechanisms of strontium's adsorption by Saccharomyces cerevisiae: Contribution of surface and intracellular uptakes. AB - The objective of this work was to explore the mechanisms participating in strontium sorption by living Saccharomyces cerevisiae (S. cerevisiae). The location of strontium adsorbed by S. cerevisiae was studied by our plasmolysis treatment. The contribution of physical and chemical mechanisms was determined quantitatively by desorption and blockage of functional groups. Moreover, our results indicated that bioaccumulation also played a major role in biosorption by living cells. Thus, supplementary methods including 2-DE (two-dimensional electrophoresis) and Matrix-Assisted Laser Desorption/Ionization Tandem Time of Flight Mass Spectrometry (MALDI-TOF-TOF) were employed to analyze the different proteins. The subsequent desorption % of Sr2+ by Distilled Water (DW), NH4NO3 and EDTA-Na2 from Sr2+ loaded sorbents indicated a minor role for physical adsorption, while ion exchange and complexation were responsible for approximately 20% and 40%. Specific blockage of functional groups revealed that carboxyl and amine groups played an important role in Sr2+ binding to the living S. cerevisiae. From our MALDI-TOF-TOF results, we concluded that 38 proteins showed up-regulated expression profiles and 11 proteins showed down-regulated after biosorption. Moreover, proteins belong to: phagocytic function (Act1p); ion channel (S-adenosylmethionine synthase); glycolysis (Tubulin) may directly involve in strontium bioaccumulation. In conclusion, the present work indicates that the strontium sorption mechanism by living S. cerevisiae is complicated including ion-exchange along with complexation as the main mechanism, whereas the other mechanisms such as physical adsorption play a minor contribution. Metabolically-dependent proteins may play an important role in bioaccumulation. PMID- 30300808 TI - Sorption and desorption of phenanthrene on biodegradable poly(butylene adipate co terephtalate) microplastics. AB - Biodegradable plastics, as alternatives to conventional plastics, are increasingly used, but their interactions with organic pollutants are still unknown. In this study, the sorption and desorption behaviors on a type of biodegradable plastic-poly(butylene adipate co-terephtalate) (PBAT) were investigated, and at the same time two types of conventional plastics polyethylene (PEc and PEv) and polystyrene (PS) were used for comparison. Phenanthrene (PHEN) was chosen as one of representative organic pollutants. Results indicated that the sorption and desorption capacities of PBAT were not only higher than those of the other types of microplastics, but also higher than those of carbonaceous geosorbents. The surface area normalized results illustrated that sorption and desorption of the microplastics were positively correlated with their abundance of rubbery subfraction. The sorption kinetic results showed that the sorption rates of PBAT and PEc were higher than PEv and PS. The effects of water chemistry factors including salinity, dissolved organic matter and Cu2+ ion on the sorption process displayed the same trend, but the degrees of influence on the four microplastics differed. The degrees of influence were mainly dependent on the abundance of rubbery subfraction for microplastics. These findings indicate that the biodegradable poly(butylene adipate co terephtalate) microplastics are actually stronger vectors than the conventional microplastics, and crystallization characteristics of the microplastics have great influences on the vector effect. PMID- 30300809 TI - Intermittent operating characteristics of an ecological soil system with two stage water distribution for wastewater treatment. AB - Ecological soil systems (ESSs) are usually used to remove nitrogen from wastewater. Due to the poor denitrification performance of traditional ecological soil systems (ESSs), this study proposes a two-stage water distribution system to improve the nitrogen removal. The effects of different distribution ratios on the system treatment effect were studied in an intermittent operation mode. After determining the optimal distribution ratio and intermittent operation conditions, the dynamics of system inflow, outflow, and nitrogen removal were monitored. Theoretical analysis of the denitrification mechanism was carried out. The results showed that the optimum water distribution ratio was 2: 1, and a mean total nitrogen removal rate of 60.42% was achieved, which is 23.09% greater than that is typically achieved by the single-section ecological system. Under optimum distribution ratio conditions, the system also demonstrated effective removal of chemical oxygen demand (COD), total phosphorus (TP) and ammonia nitrogen (NH4+ N), allowing the effluent to satisfy China's urban sewage treatment plant level B emission standards. PMID- 30300810 TI - The effect of flunixin meglumine, firocoxib and meloxicam on the uterine mobility of equine embryos. AB - Embryo mobility occurs as a result of prostaglandin production by the embryo and endometrium, promoting uterine smooth muscle contractions, which propels the embryonic vesicle through the lumen. Non-steroidal anti-inflammatory drugs (NSAIDs), as flunixin meglumine, are routinely used in equine medicine and can alter the conceptus mobility if applied in early pregnancy, which may impair maternal recognition of pregnancy. The objective of this study was to evaluate and compare the effect of flunixin meglumine (FM; 1.1 mg/kg IV), firocoxib (FIRO; 0.2 mg/kg PO), and meloxicam (ML; 0.6 mg/kg, IV), on the embryo mobility. Thirty mares were divided into three groups (n = 10 per treatment). After the pregnancy diagnosis on day 12 after ovulation, the embryo mobility was evaluated by transrectal ultrasonography every 5 min for 1 h in order to visualize the location of the embryo. In all mares, three evaluations were performed: immediately before treatment (pre-treatment), after NSAID administration and 24 h after treatment. In group FM, embryo mobility decreased, from 5.8 +/- 0.3 movements/hour (m/h) to 2.3 +/- 0.5 m/h (p < 0.05) and, after 24 h the values were similar to the pre-treatment evaluation (5.9 +/- 0.2 m/h). Likewise, ML treatment caused a decrease of embryo movements, from 5.9 +/- 0.3 to 1.9 +/- 0.3 m/h (p < 0.05), 24 h after treatment values were 5.7 +/- 0.4 m/h. Treatment with FIRO did not interfere with embryo mobility (5.7 +/- 0.4; 5.8 +/- 0.3 and 5.6 +/- 0.3 embryo movements in the first, second and third evaluation, respectively). In conclusion, FIRO was the only NSAID that did not alter the embryo mobility and may be the safest NSAID for use in early pregnant mares. PMID- 30300811 TI - A quantitative morphological analysis of three-dimensional CT coxal bone images of contemporary Japanese using homologous models for sex and age estimation. AB - Sexual dimorphisms and age-dependent morphological features of the human coxal bone were quantitatively analyzed using homologous models created from three dimensional (3D) computed tomography images of the pelvis (male: 514 samples, female: 388 samples, age 16-100). Bilateral average coxal images of each sex and age decade were generated separately through principle component analyses (PCA). By measuring average point-to-point distances of 8472 corresponding points (average corresponding point differences [ACPDs]) between each homologous coxal image and the average images, the sex of more than 93% of the samples was correctly assigned. Some principal components (PCs) detected in PCA of the homologous models of the samples correlated fairly well with age and are affected by features of the curvature of the iliac crest, the arcuate line and the greater sciatic notch. Moreover, separate PCA using the average images of each age decade successfully detected the first PCs, which were strongly correlated with age. However, neither multiple regression analysis using PCs related to age nor comparison of ACPDs with the average images of each age decade could produce accurate results for age decade assignment of unknown (blind) samples. Therefore, more detailed analysis of age-dependent morphological features would be necessary for actual age estimation. In addition, some laterality or left and right shape difference of the coxal bone images was also elucidated, and was more significant in females. Analysis of 3D structures using homologous models and PCA appears to be a potential technique to detect subsistent morphological changes of bones. PMID- 30300812 TI - Permeability and microstructure of cholesterol-depleted skin lipid membranes and human stratum corneum. AB - Cholesterol (Chol) is one of the major skin barrier lipids. The physiological level of Chol in the stratum corneum (SC) appears to exceed its miscibility with other barrier lipids, as some Chol is phase separated. Chol synthesis is essential for epidermal homeostasis, yet the role of these Chol domains in SC permeability is unknown. We investigated the impact of Chol depletion on the permeability properties and microstructure of model membranes and human SC. X-ray powder diffraction of membranes constructed from isolated human skin ceramides or synthetic ceramides confirmed that only approximately half of the normal Chol amount can be incorporated in either long or short periodicity lamellar phases. The long periodicity lipid arrangement persisted even in the absence of Chol. Infrared spectroscopy suggested that Chol had negligible effects on the lipid chain order and packing at physiological skin temperature. Chol depletion of the model membranes or isolated human SC did not compromise the barrier function to water and two model permeants. On the contrary, the membrane with the Chol content reduced to 40% of the normal value, where no separated Chol was observed, was significantly less permeable than the control. Thus, a 0.4:1:1 M ratio of Chol/ceramides/fatty acids appears sufficient for skin lipids to limit water loss and prevent the entry of environmental substances. We speculate that the SC Chol domains may have roles in the skin other than barrier function. PMID- 30300813 TI - The sensitivity of satellite-based PM2.5 estimates to its inputs: Implications to model development in data-poor regions. AB - Exposure to fine particulate matter (PM2.5) has been associated with a wide range of negative health outcomes. The overwhelming majority of the epidemiological studies that helped establish such associations was conducted in regions with sufficient ground observations and other supporting data, i.e., the data-rich regions. However, air pollution health effects research in the data-poor regions, where pollution levels are often the highest, is still very limited due to the lack of high-quality exposure estimates. To improve our understanding of the desired input datasets for the application of satellite-based PM2.5 exposure models in data-poor areas, we applied a Bayesian ensemble model in the southeast U.S. that was selected as a representative data-rich region. We designed four groups of sensitivity tests to simulate various data-poor scenarios. The factors considered that would influence the model performance included the temporal sampling frequency of the monitors, the number of ground monitors, the accuracy of the chemical transport model simulation of PM2.5 concentrations, and different combinations of the additional predictors. While our full model achieved a 10 fold cross-validated (CV) R2 of 0.82, we found that when reducing the sampling frequency from the current 1-in-3 day to 1-in-9 day, the CV R2 decreased to 0.58, and the predictions could not capture the daily variations of PM2.5. Half of the current stations (i.e., 30 monitors) could still support a robust model with a CV R2 of 0.79. With 20 monitors, the CV R2 decreased from 0.71 to 0.55 when 100% additional random errors were added to the original CMAQ simulations. However, with a sufficient number of ground monitors (e.g., 30 monitors), our Bayesian ensemble model had the ability to tolerate CMAQ errors with only a slight decrease in CV R2 (from 0.79 to 0.75). With fewer than 15 monitors, our full model collapsed and failed to fit any covariates, while the models with only time varying variables could still converge even with only five monitors left. A model without the land use parameters lacked fine spatial details in the prediction maps, but could still capture the daily variability of PM2.5 (CV R2 >= 0.67) and might support a study of the acute health effects of PM2.5 exposure. PMID- 30300814 TI - Variability of urinary concentrations of non-persistent chemicals in pregnant women and school-aged children. AB - BACKGROUND: Exposome studies are challenged by exposure misclassification for non persistent chemicals, whose temporal variability contributes to bias in dose response functions. OBJECTIVES: We evaluated the variability of urinary concentrations of 24 non-persistent chemicals: 10 phthalate metabolites, 7 phenols, 6 organophosphate (OP) pesticide metabolites, and cotinine, between weeks from different pregnancy trimesters in pregnant women, and between days and between seasons in children. METHODS: 154 pregnant women and 152 children from six European countries were enrolled in 2014-2015. Pregnant women provided three urine samples over a day (morning, midday, and night), for one week in the 2nd and 3rd pregnancy trimesters. Children provided two urines a day (morning and night), over two one-week periods, six months apart. We pooled all samples for a given subject that were collected within a week. In children, we also made four daily pools (combining morning and night voids) during the last four days of the first follow-up week. Pools were analyzed for all 24 metabolites of interest. We calculated intraclass-correlation coefficients (ICC) and estimated the number of pools needed to obtain an ICC above 0.80. RESULTS: All phthalate metabolites and phenols were detected in >90% of pools whereas certain OP pesticide metabolites and cotinine were detected in <43% of pools. We observed fair (ICC = 0.40-0.59) to good (0.60-0.74) between-day reliability of the pools of two samples in children for all chemicals. Reliability was poor (<0.40) to fair between trimesters in pregnant women and between seasons in children. For most chemicals, three daily pools of two urines each (for weekly exposure windows) and four weekly pools of 15-20 urines each would be necessary to obtain an ICC above 0.80. CONCLUSIONS: This quantification of the variability of biomarker measurements of many non-persistent chemicals during several time windows shows that for many of these compounds a few dozen samples are required to accurately assess exposure over periods encompassing several trimesters or months. PMID- 30300815 TI - The association of traffic-related air and noise pollution with maternal blood pressure and hypertensive disorders of pregnancy in the HOME study cohort. AB - Traffic-related air and noise pollution may increase the risk for cardiovascular disorders, especially among susceptible populations like pregnant women. The objective of this study was to evaluate the association of exposure to traffic related air pollution and traffic noise with blood pressure in pregnant women. We extracted systolic blood pressure (SBP) and diastolic blood pressure (DBP) at >=20 weeks gestation, as well as hypertensive disorders of pregnancy from medical records in the HOME Study, a prospective pregnancy and birth cohort from Cincinnati, OH (n = 370). We estimated exposure to elemental carbon attributable to traffic (ECAT),1 a marker of traffic-related air pollution, at women's residences at ~20 weeks gestation using a validated land use regression model and traffic noise using a publicly available transportation noise model. We used linear mixed models and modified Poisson regression adjusted for covariates to examine associations of ECAT and traffic noise with blood pressure and hypertensive disorders of pregnancy risk, respectively. In adjusted models, we found a 1.6 (95% CI = 0.02, 3.3; p = 0.048) mm Hg increase in SBP associated with an interquartile range increase in ECAT concentration; the association was stronger after adjusting for traffic noise (1.9 mm Hg, 95% = 0.1, 3.7; p = 0.035). ECAT concentrations were not significantly associated with DBP or hypertensive disorders of pregnancy, and traffic noise was not associated with SBP, DBP, or hypertensive disorders of pregnancy. There was no evidence of a joint effect of traffic noise and ECAT on any outcome. In this cohort, higher residential traffic-related air pollution exposure at ~20 weeks gestation was associated with higher SBP in late pregnancy. It is important for future studies of traffic-related air or noise pollution to jointly consider both exposures and neighborhood characteristics given their correlation and potential cumulative impact on cardiovascular health. PMID- 30300817 TI - Natural variability and modulation by environmental stressors of global genomic cytosine methylation levels in a freshwater crustacean, Gammarus fossarum. AB - To improve the assessment of aquatic organism responses to environmental stressors, there is an interest in studying epigenetic marks in addition to other validated biomarkers. Indeed, the epigenetic marks may be influenced by the surrounding environment. Non-model invertebrates such as gammarids are sentinel organisms representative of the diversity of natural stream communities. Despite their ecologically relevance, the epigenetic responses have been to date poorly documented in these species. The present study explores the measurement of the global cytosine methylation level in the genome of the freshwater crustacean Gammarus fossarum. In a first step, natural variability of global cytosine methylation level (basal level) was assessed by studying the effect of sex, age and sampling site of organisms. Results showed a significant effect of age and sampling site. In a second step, effects of water temperature and food starvation were studied. For both factors, a hypermethylation was observed after 1 month of exposure. In a third step, gammarids were exposed to a range of environmentally relevant cadmium concentrations (0.05-5 MUg/L) in order to assess the effect of a chemical stress. Whatever the cadmium concentration used, a significant hypomethylation was observed after 14 days followed by a trend for hypermethylation after 1 month of exposure. These results are the first ones dealing with the 5C-methylation status in gammarids. The results constitute potential markers of environmental stresses in relevant sentinel species widely used in ecotoxicological studies. PMID- 30300816 TI - Urinary trace metals individually and in mixtures in association with preterm birth. AB - One in ten infants born in the United States is born preterm, or prior to 37 weeks gestation. Exposure to elevated levels of metals, such as lead and arsenic, has been linked to higher risk of preterm birth (PTB), but consequences of lower levels of exposure and less studied metals are unclear. We examined the associations between 17 urinary trace metals individually and in mixtures in relation to PTB. The LIFECODES birth cohort enrolled pregnant women at <15 weeks gestation at Brigham and Women's Hospital in Boston. We selected cases of PTB (n = 99) and unmatched controls (n = 291) and analyzed urine samples for a panel of trace metals (median: 26 weeks gestation). We used logistic regression models to calculate the odds ratio (OR) for PTB and subtypes of PTB based on presentation at delivery. Subtypes included spontaneous and placental PTB. We used elastic net (ENET) regularization to identify individual metals or pairwise interactions that had the strongest associations with PTB, and principal components analysis (PCA) to identify classes of exposures associated with the outcome. We observed increased odds of PTB (OR: 1.41, 95% Confidence Interval [CI]: 1.12, 1.78) in association with an interquartile range difference in urinary copper (Cu). We also observed an increased OR for selenium (OR: 1.33, 95% CI: 0.98, 1.81). ENET selected Cu as the most important trace metal associated with PTB. PCA identified 3 principal components (PCs) that roughly reflected exposure to toxic metals, essential metals, and metals with seafood as a common source of exposure. PCs reflecting essential metals were associated with increased odds of overall and spontaneous PTB. Maternal urinary copper in the third trimester was associated with increased risk of PTB, and statistical analyses for mixtures indicated that after accounting for correlation this metal was the most important statistical predictor of the outcome. PMID- 30300818 TI - Women with compulsive buying or gambling disorder: Similar profiles for different behavioural addictions. AB - The aim of the present study was to examine the differences in sociodemographic and clinical characteristics of 104 women diagnosed with compulsive buying behaviour (CBB = 55) or gambling disorder (GD = 49) treated at three public hospitals unit specialized in behavioural addictions from January 2004 to December 2015. Significant between-group differences in sociodemographic variables were observed for cohabitation status (living with a partner or not) and educational level, with a higher percentage of women in the GD group cohabiting (x2 (1), p = .029). By contrast, the CBB group had a significantly higher educational level (x2 (1) = 7.4, p = .007). There were no significant differences between the groups in age of onset, age at treatment initiation, age at the onset of behavioural problems, or in the years elapsed until presenting addiction problems. However, there were significant between-group differences in the amount of money spent weekly (F (1.100) = 4.9, p = .028), with women in the CBB group spending on average ?289.4/week (SD, 412.4) versus ?151/week (SD, 141.23) in the GD group. The CBB group had significantly more depressive disorders compared to the GD group (x2(1) = 5.4, p = .020). In contrast, the GD group presented significantly more tobacco use than the CBB group (x2(1) = 1.19, p = .000). This study suggests that women with CBB or GD share more characteristics than differences and the treatment approaches must take into account gender related factors. PMID- 30300819 TI - Spinal cord infarction with ipsilateral segmental neuropathic pain and flaccid paralysis. A functional role for human afferent ventral root small sensory fibres. AB - This paper illustrates the cases of two patients with an acute onset of right brachial neuropathic pain, flaccid paralysis and contralateral thermal and thermal pain hypoesthesia, without posterior column impairment nor pyramidal signs below the segmental lesion. MRI showed right sided spinal cord infarction, in the anterior spinal artery territory between C1 and C5 in one patient and between C3 and C7 in the other. Contact Heat Evoked Potentials and Quantitative Thermal Sensory testing are consistent with contralateral, but not ipsilateral, spinothalamic tract involvement. Electromyographic results established ipsilateral segmental denervation and somatosensory evoked responses were consistent with dorsal column sparing. Unilateral anterior cervical spinal cord infarction may present with acute ipsilateral segmental neuropathic pain, lower motor neurone-type weakness, contralateral thermoanalgesia and no pyramidal signs. The ipsilateral pain provides novel evidence that in some instances, ventral roots can play a role in nociception in humans. The infarcted territory may result from occlusion of a sulcal commissural artery or a number of more proximal vessels (including a single or duplicated anterior spinal artery, vertebral arteries or feeding radicular arteries). PMID- 30300820 TI - 360 degrees multiparametric imaging atomic force microscopy: A method for three dimensional nanomechanical mapping. AB - Atomic Force Microscopy (AFM) has been intensively used for imaging, characterization and manipulation at the micro- and nanoscale. Taking into account that the material is usually anisotropic, it needs to be characterized in various regions and orientations. Although recent advances of AFM techniques have allowed for large area scan of the sample on a two-dimensional plane, mapping a three-dimensional (3D) sample at a full orientation of 360 degrees remains challenge. This paper reports a multiparametric imaging atomic force microscope via robot technique for 360 degrees mapping and 3D reconstruction of the sample's topography and nanomechanical properties. The system is developed by integrating a three degrees of freedom (DoFs) high-precision rotation stage and a home positioning approach is proposed to compensate for the eccentric distance between the cross-section center of the sample and the ration center of the stage. With this method, the sample surface can be fully mapped by the force distance-based AFM via rotating the sample with a complete orientation. 360 degrees multiparametric mapping and 3D reconstruction results (e.g., topography, adhesion, modulus, energy dissipation) of a human hair demonstrate practicability and reliability of the proposed method. PMID- 30300821 TI - NF-kappaB signaling activation via increases in BRD2 and BRD4 confers resistance to the bromodomain inhibitor I-BET151 in U937 cells. AB - Novel epigenetic therapies targeting bromodomain and extra-terminal (BET) family proteins have shown therapeutic efficacy in diverse hematologic malignancies and solid cancers. However, the mechanism of resistance remains poorly understood. In the present study, we evaluated the mechanism of resistance to the BET inhibitor I-BET151 and its signaling pathway to overcome resistance in U937 cells. Treatment with 10 MUM I-BET151 significantly induced growth inhibition, apoptosis, and cell cycle modulation, including increases in sub-G1 and G1 phases and decreases in S and G2/M phases, in U937 cells. However, no significant changes in these factors were detected in I-BET151-resistant U937 (U937R) cells. Combined treatment with I-BET151 and IKK inhibitor VII synergistically induced apoptosis in U937 and U937R cells. Increased expression of bromodomain-containing protein (BRD) 2, BRD4, and nuclear NF-kappaBp65 proteins was detected in U937R cells. IKK inhibitor VII inhibited the activation of NF-kappaBp65 protein in the nuclear fraction of U937R cells. These findings suggest that resistance to I BET151 in U937R cells is related to constitutive activation of the NF-kappaB signaling pathway via increased expression of both BRD2 and BRD4. Targeting the NF-kappaB signaling pathway may be an effective therapeutic strategy to enhance or restore the sensitivity to I-BET151 in U937 cells.

AB - BACKGROUND: Patients with acute myeloid leukemia (AML) treated with intensive chemotherapy may require re-induction based on the evaluation of day 14 bone marrow biopsy. METHODS: A retrospective chart review was performed to evaluate adult patients with AML who received re-induction with fludarabine, high dose cytarabine and granulocyte colony stimulating factor (FLAG) regimen for residual disease (>= 5% blasts by morphology) on day 14 bone marrow examination between September 2012 and July 2017 at our institution. RESULTS: We identified 27 patients who received FLAG therapy for treatment of residual disease on day 14 marrow examination following initial induction. The median age at diagnosis was 61 years and the majority of patients had poor risk AML. The overall response rate was 78% and 15 patients proceeded to allogeneic hematopoietic stem cell transplantation. CONCLUSION: The regimen was well tolerated and is a viable re induction option for patients with residual disease on a day 14 bone marrow.

AB - Gemtuzumab ozogamicin (GO), the first antibody-drug conjugate (ADC), has attracted the interest of hematologists because more than 90% of acute myeloid leukemia (AML) blasts express its target, CD33. Although GO and subsequently developed ADCs depend on lysosomes for activation, lysosome number and activity in tumor cells has not been well elucidated. In this study, we investigated whether an mTORC1/2 kinase inhibitor, PP242, which was reported to activate lysosomal function, potentiates the cytotoxicity of GO in AML cells. Eight AML cell lines (U937, THP-1, SKM-1, SKK-1, SKNO-1, HL-60, MARIMO and KO52) were treated with GO and PP242. The cytotoxic effect of GO was enhanced by concurrent treatment with a non-cytotoxic concentration (500 nM) of PP242 in most cell lines, except MARIMO and KO52 cells. We then used LysoTracker to label acidic lysosomes in U937, THP-1, SKM-1, MARIMO and KO52 cells. LysoTracker fluorescence was dramatically increased by treatment with PP242 in U937, THP-1 and SKM-1 cells, and the intensified fluorescence was retained with PP242 + GO. In contrast, PP242 did not induce a significant increase in fluorescence in MARIMO cells, consistent with the lack of combinatory cytotoxicity. LysoTracker fluorescence was also increased by PP242 in KO52 cells, which have been reported to strongly express multidrug resistance (MDR). Further, PP242 suppressed GO induced Chk1 activation and G2/M cell cycle arrest, which in turn triggered cell cycle promotion and cell death. These results indicate that inhibition of mTORC1/2 kinase by PP242 enhanced the cytotoxicity of GO by increasing lysosomal compartments and promoting the cell cycle via suppression of GO-induced Chk1 activation. This combination may represent an attractive new therapeutic strategy for the treatment of leukemia. PMID- 30300824 TI - Hole free phase plate tomography for materials sciences samples. AB - We report, for the first time, the three dimensional reconstruction (3D) of a transistor from a microprocessor chip and roughness of molecular electronic junction obtained by electron tomography with Hole Free Phase Plate (HFPP) imaging. The HFPP appears to enhance contrast between inorganic materials and also increase the visibility of interfaces between different materials. We demonstrate that the degree of enhancement varies depending on material and thickness of the samples using experimental and simulation data. PMID- 30300825 TI - Ion transmission through a dielectric hollow tip for scanning probe microscopy. AB - We present a new concept for scanning probe microscopy characterization of molecular microstructures. It is based on a thin capillary using as a sharp tip to probe and map the morphology of a surface. In our experiment a collimated ion beam is formed by tungsten ions passing through a quartz tapered capillary with a 100-nm aperture and enters a 2D position-sensitive detector. We demonstrate that such ions are capable of producing the image of a dielectric nanoaperture in the case of low-dose ion beam. Ion transmission through a nanoscale capillary opens the door to observing photodesorption of large organic molecular ions with high spatially-element resolution using the combination of a hollow-tip vacuum scanner with time-of-flight mass spectrometer.

AB - Various data-driven voxel-wise measures derived from resting-state functional magnetic resonance imaging (rs-fMRI) have been developed to characterize spontaneous brain activity. These measures have been widely applied to explore brain functional changes in schizophrenia and have enjoyed significant success in unraveling the neural mechanisms of this disorder. However, their spatial and temporal coupling alterations in schizophrenia remain largely unknown. To address this issue, 88 schizophrenia patients and 116 gender- and age-matched healthy controls underwent rs-fMRI examinations. Kendall's W was used to calculate volume wise (across voxels) and voxel-wise (across time windows) concordance among multiple commonly used measures, including fractional amplitude of low frequency fluctuations, regional homogeneity, voxel-mirrored homotopic connectivity, degree centrality and global signal connectivity. Inter-group differences in the concordance were investigated. Results revealed that whole gray matter volume wise concordance was reduced in schizophrenia patients relative to healthy controls. Although two groups showed similar spatial distributions of the voxel wise concordance, quantitative comparison analysis revealed that schizophrenia patients exhibited decreased voxel-wise concordance in gray matter areas spanning the bilateral frontal, parietal, occipital, temporal and insular cortices. In addition, these concordance changes were negatively correlated with onset age in schizophrenia patients. Our findings suggest that the concordance approaches may provide new insights into the neural mechanisms of schizophrenia and have the potential to be extended to neuropsychiatric disorders. PMID- 30300828 TI - Potentiality of microemulsion systems in treatment of ophthalmic disorders: Keratoconus and dry eye syndrome - In vivo study. AB - Microemulsions are widely studied as potential ocular drug delivery vehicles. In the present study we show the versatility of possible use microemulsions as ocular delivery vehicle. The ME is loaded with a hydrophilic drug, riboflavin phosphate (RFP) and a lipophilic, docosahexaenoic acid in triglyceride form (TG DHA), each separately. These drugs treat keratoconus and dry eye syndrome, respectively. The advantage of using ME loaded with RFP is in overcoming eye epithelium debridement during collagen cross-linking therapy for treatment of keratoconus. ME loaded with lipophilic TG-DHA provides convenient dosage in liquid aqueous form of administration of highly lipophilic TG-DHA, which is known as a protective molecule in dry eye syndrome. The capability of RFP-loaded MEs was demonstrated in terms of improvement of biomechanical strength of the rabbit cornea, as a result of successful penetration of RFP through the intact epithelium. TG-DHA-loaded microemulsion applied topically onto an eye with induced dry eye syndrome showed the significant relief of the dry eye condition. PMID- 30300827 TI - Expression of the Immune Checkpoint Modulator OX40 in Acute Lymphoblastic Leukemia Is Associated with BCR-ABL Positivity. AB - OX40 and its ligand are members of the TNF/TNF receptor superfamily, which includes various molecules influencing cellular signaling and function of both tumor and immune cells. The ability of OX40 to promote proliferation and differentiation of activated T cells fueled present attempts to modulate this immune checkpoint to reinforce antitumor immunity. While we recently found evidence for the involvement of OX40 in pathophysiology of acute myeloid leukemia including natural killer (NK) cell immunosurveillance, less is known on its role in acute lymphoblastic leukemia (ALL). In the present study, OX40 expression on ALL cells was significantly associated with positivity for the adverse risk factor BCR-ABL. In line, signaling via OX40 increased metabolic activity of primary ALL cells and resulted in release of cytokines involved in disease pathophysiology. Furthermore, interaction of ALL-expressed OX40 with its cognate ligand on NK cells stimulated ALL cell lysis. The data presented thus not only identify the yet unknown involvement of OX40/OX40L in ALL pathophysiology and NK cell immunosurveillance but also point to the necessity to thoroughly consider the consequences of modulating the OX40/OX40L molecule system beyond its effects on T cells when developing OX40-targeting approaches for cancer immunotherapy. PMID- 30300829 TI - Entrapment and growth of Chlamydomonas reinhardtii in biocompatible silica hydrogels. AB - In this work, we aimed at improved viability and growth of the microalga Chlamydomonas reinhardtii in transparent silica hydrogels based on low-ethanol, low-sodium and low-propylamine synthesis. Investigation into replacement of conventional base KOH by buffers dipotassium phosphate and tris(hydroxymethyl)aminomethane along with increased precursor concentrations yielded an aqueous synthesis route which provided a gelation within 10 min, absorptions below 0.1 and elastic moduli of 0.04-4.23 kPa. The abrasion resistance enhanced by 41% compared to calcium alginate hydrogels and increased to 70-85% residual material on addition of chitosan. Entrapment of microalgae in low-sodium and low-propylamine silica hydrogels maintained the PSII quantum yield above 0.3 and growth rates of 0.23 +/- 0.01 d-1, similarly to cells entrapped in calcium alginate. These promising results pave the way for the entrapment of sensitive, photosynthetically active and growing cells for in robust biotechnological applications. PMID- 30300830 TI - Preparation of antimicrobial gold and silver nanoparticles from tea leaf extracts. AB - Gold and silver nanoparticles were prepared from the green tea and black tea extracts of the leaves of Camellia sinensis. The metal nanoparticle solutions were obtained by reacting HAuCl4 or AgNO3 aqueous solutions with aqueous NaHCO3 and tea leaf extracts, which were obtained from used tea leaves at low temperature, under ambient conditions. The nanoparticles were stable at room temperature and had a uniform particle size (Au: ~10 nm, Ag: ~30 nm). Nanoparticle-immobilized cotton cloths were then prepared, which displayed high antibacterial activity and a characteristic color, thereby showing potential application as antimicrobial pigments. This study provides a means of utilizing used tea leaves, which would otherwise be considered waste products. PMID- 30300831 TI - Synthesis of ultra-small Rh nanoparticles congregated over DNA for catalysis and SERS applications. AB - Exploration of rare earth metals for the Surface Enhanced Raman Scattering (SERS) is greatly preferred to identify probe molecules even at nano molar level. Highly stable Rh nanoparticles (NPs) which are ultra-small size have been prepared within 20 min of reaction time as a colloidal solution using a bio-molecular scaffold DNA and NaBH4 as a reducing agent under room temperature. While keeping metal ion concentration fixed and by making difference in DNA concentration, three different sets of Rh@DNA such as 0.08, 0.085 and 0.09 M were formed as nanochains like structure with varying diameters. The average chain length of Rh NPs for varying concentrations of DNA is ~98 nm and the Rh particles size is below 5 nm in all the cases. These ultra-small Rh NPs have been utilized for two distinct potential applications such as in catalysis and SERS studies. From the catalysis reaction, reduction of 4-Nitro benzaldehyde to 4-amino benzaldehyde, Rh@DNA (0.08 M) has shown rate constant value of 0.26 min-1 which is highest among other concentrations studied. SERS study revealed that the calculated Enhancement Factor (EF) value was 1.19 * 105 for Rh@DNA (0.08 M) which is highest while compared with other concentrations. Apart from catalysis and SERS, the as synthesized Rh NPs can find applications in other interdisciplinary fields such as organic catalysis, electro-catalysis and so on in near future. PMID- 30300832 TI - Poly(d,l-lactic-co-glycolic acid) (PLGA) hollow fiber with segmental switchability of its chains sensitive to NIR light for synergistic cancer therapy. AB - This work introduces a new fibrous system for synergistic cancer therapy. The system consists of poly(d,l-lactic-co-glycolic acid) (PLGA) fibers with a core encapsulating an anticancer drug and a shell entrapping gold nanorods (AuNRs) as a photothermal agent. On exposure to NIR light, the photothermal agent generates heat to raise the local temperature of the fibers. If the temperature is above a glass transition (Tg) of the polymer, the polymer chains will be mobile, increasing free volume in size within the shell. As a result, a rapid release of the drug can be achieved. When NIR light is turned off, the release will stop with inactivity of the photothermal agent, followed by freezing the segmental motion of the polymer chains. The on-off switching of NIR light in a time controllable manner allows a repeated and accurate release of the drug, leading to the significant enhancement of anticancer activity in combination with the hyperthermia effect arising from the photothermal agent. PMID- 30300833 TI - Biocompatible graphene-based nanoagent with NIR and magnetism dual-responses for effective bacterial killing and removal. AB - Antibiotics have been widely used in clinical applications to treat pathogenic infections at present, but the problem of drug-resistance associated with the abuse of antibiotics has become a large threat to human beings. Herein, we developed an antibacterial nanoagent by coating quaternized chitosan (QCS) on the surface of Fe3O4 nanoparticles-anchored graphene oxide (GO), which enabled QCS and GO to achieve synergistic effects on killing the drug-resistant bacteria. Systematical antibacterial experiments showed that the prepared nanoagent had antibacterial ability, which was significantly enhanced after the introduction of near-infrared (NIR). Importantly, the nanoagent could be easily recycled and reused without the reduction of the antibacterial ability. During the test time, this nanoagent exhibited no obviously toxic side effect to cells. Given the above advantages, we anticipate that the nanoagent has a promising future in various applications such as wound disinfection, water purification, and surface sterilization of medical devices. PMID- 30300834 TI - An investigation into the release behavior of solid lipid microparticles in different simulated gastrointestinal fluids. AB - In recent years there has been a growing interest in solid lipid-based systems, particularly in solid lipid microparticles (SLMs); however, only very few studies deeply investigated the dissolution behaviour of orally delivered-SLMs. The present study provides new insights about the release performance in different gastrointestinal fluids of SLMs containing a freely water soluble drug (caffeine, as BCS class I drug). Three different formulations of SLMs were prepared by spray congealing using lipid excipients belonging to three chemical classes: fatty acids, triglycerides and waxes. The dissolution profiles of caffeine were investigated using various updated biorelevant dissolution media simulating the conditions of the gastrointestinal tract (gastric tract and proximal human intestine). The profiles were statistically compared and the morphological changes of the particles after dissolution were assessed by SEM analysis. The influence of the SLMs composition resulted to be crucial on the dissolution behavior in the case of bigger particles (>250 MUm), while smaller SLMs (100-250 MUm) were mainly affected by the fluid composition. Moreover, regardless of the particle size, greater differences in drug release profiles were noted by using different intestinal media compared to those obtained in gastric media. In particular, the drug release from fatty acid and triglyceride-based SLMs was more controlled in the phosphate buffer than in the intestinal biorelevant media; while the opposite behavior was noticed for waxy-bases SLMs. Overall, the present study provides interesting insights which can be useful for the design of a multiparticulated solid lipid formulation. PMID- 30300835 TI - Long-term exposure to high-sucrose diet down-regulates hepatic endoplasmic reticulum-stress adaptive pathways and potentiates de novo lipogenesis in weaned male mice. AB - Childhood consumption of added sugars, such as sucrose, has been associated to increased risk of metabolic syndrome (MetS) and nonalcoholic fatty liver disease (NAFLD). Although the mechanisms underlying NAFLD onset are incompletely defined, recent evidence has proposed a role for the endoplasmic reticulum (ER) stress. Thus, the present study sought to investigate the metabolic outcomes of high sucrose intake on weaned Swiss mice fed a 25% sucrose diet for 30, 60 and 90 days in comparison to regular chow-fed controls. High-sucrose feeding promoted progressive metabolic and oxidative disturbances, starting from fasting and fed hyperglycemia, hyperinsulinemia, glucose intolerance and increased adiposity at 30-days; passing by insulin resistance, hypertriglyceridemia and NAFLD onset at 60 days; until late hepatic oxidative damage at 90 days. In parallel, assessment of transcriptional and/or translational levels of de novo lipogenesis (DNL) and ER stress markers showed up-regulation of both fatty acid synthesis (ChREBP and SCD1) and oxidation (PPARalpha and CPT-1alpha), as well as overexpression of unfolded protein response sensors (IRE1alpha, PERK and ATF6), chaperones (GRP78 and PDIA1) and antioxidant defense (NRF2) genes at 30 days. At 60 days, fatty acid oxidation genes were down-regulated, and ER stress switched over toward a proapoptotic pattern via up-regulation of BAK protein and CHOP gene levels. Finally, down-regulation of both NRF2 and CPT-1alpha protein levels led to late up-regulation of SREBP-1c and exponential raise of fatty acids synthesis. In conclusion, our study originally demonstrates a temporal relationship between DNL and ER stress pathways toward MetS and NAFLD development on weaned rats fed a high-sucrose diet. PMID- 30300836 TI - Bio-accessible milk casein derived tripeptide (LLY) mediates overlapping anti- inflammatory and anti-oxidative effects under cellular (Caco-2) and in vivo milieu. AB - Inflammation and oxidative stress are closely linked patho-physiological processes which occur concurrently in many diseased conditions. Recently, interdependence between these two processes explains the antioxidant paradox associated with failure to select appropriate agents required for prevention of diseases known to be induced by oxidative stress. Present study established the overlapping anti-inflammatory and anti-oxidative potential along with bio accessibility of milk casein derived tripeptide (LLY). Tripeptide exhibited anti inflammatory response under ex vivo conditions by suppressing (P<.01) mice splenocytes proliferation and modulating their cytokines (IFN-gamma, IL-10 and TGF-beta) with improved phagocytosis of peritoneal macrophages. Conversely, tripeptide displayed extraordinary radical scavenging ability and cellular anti oxidative potential using chemical assays and H2O2 induced oxidative stress model on Caco-2 cells. Under cellular assessment, on one hand tripeptide inhibited (P<.01) intracellular ROS generation and reduced MDA and protein carbonyls but on the other also increased (P<.01) the activity of anti-oxidative enzyme, catalase without much effect on SOD and GPx. This anti-oxidative potential was further established by studying relative expression of genes (Nrf-2 and Keap1) and Nrf-2 nuclear translocation associated with anti-oxidative signaling in Caco-2 cells. Bio-accessibility of tripeptide and its intact transport across Caco-2 cell monolayer was also found to be 1.72+/-0.22% through PepT1 mediated transport mechanism. Besides, tripeptide displayed strong anti-oxidative and anti inflammatory potential under in vivo conditions in mice against ethanol induced oxidative stress by elevating (P<.01) liver GSH content and by decreasing (P<.01) the activities of anti-oxidative enzymes, MDA along with reduced expression of CYP2E1, PPAR-alpha, TNF-alpha and COX-2 genes than ethanol control. PMID- 30300837 TI - Obesity alters the uterine environment before pregnancy. AB - Obesity is a metabolic disorder that predisposes to numerous diseases and has become a major global public health concern. Cafeteria diet (CAF) is the animal model used for the study of obesity that more closely reflects Western diet habits. Previously, we described that CAF administration for 60 days induces obesity in female rats and their fetuses develop macrosomia. Given that, in our model, rats are not genetically modified and that obese mothers were fed standard chow during pregnancy, the aim of the current study was to test the hypothesis that obesity alters the intrauterine environment prior to pregnancy, and this may explain the exacerbated fetal weight gain. We found that uteri from obese rats during the estrous phase developed insulin resistance through mechanisms that involve the induction of uterine hypoxia and the down-regulation of the insulin receptor gene. Moreover, uterine cell proliferation was induced by obesity concomitantly with the reduction in the uterine contractile response to a beta2 AR agonist, salbutamol, and this may be consequence of the down-regulation in the uterine beta2 AR expression. We conclude that CAF-induced obesity alters the uterine environment in rats during the estrous phase and may cause the fetal macrosomia previously described by us in obese animals. The lower sensitivity of the uterus to a relaxation stimulus (salbutamol) is not a minor fact given that for implantation to occur the uterus must be relaxed for embryo nidation. Thus, the alteration in the uterine quiescence may impair implantation and, consequently, the foregoing pregnancy. PMID- 30300838 TI - Cancer epidemiology fieldwork in a resource-limited setting: Experience from the western Kenya ESCCAPE esophageal cancer case-control pilot study. AB - BACKGROUND: Case-control studies remain an important study design for aetiologic research on cancer, particularly when cohorts are not available. In addition to the potential biases inherent in this design, conducting fieldwork in settings with weak health care and information systems for cancer, such as in sub Saharan Africa, confer additional challenges which we present here with the aim to share experience to guide future studies. METHODS: We undertook a hospital-based case control study of squamous cell esophageal cancer at the Moi Teaching and Referral Hospital in Eldoret, West Kenya. Cases were recruited at endoscopy and controls from hospital wards, age and gender frequency-matched to cases. Urine, toenails, blood and tumour biopsy were collected and a questionnaire administered. RESULTS: During this pilot phase, 143 cases and 155 controls were successfully recruited. Complete questionnaire data was obtained through e-data collection. Biospecimen collection was possible with support of an already existing equipped laboratory. We introduce changes made in the main study phase, including on expansion of the control groups to allow to consideration of selection bias. CONCLUSIONS: Extra attention and funding to train and monitor data quality and biospecimen collection and collaboration of a large group held together by strong leadership are essential. We recommend studies based on regional treatment centres with their more defined catchment areas rather than in the capital cities as referral routes in multi-level health care systems are severely attrition prone. PMID- 30300839 TI - Modulation of heat-shock response is associated with Di (2-ethylhexyl) phthalate (DEHP)-induced cardiotoxicity in quail (Coturnix japonica). AB - Di(2-ethylhexyl) phthalate (DEHP) is an omnipresent environmental pollutant with endocrine disrupting properties. As a plasticizer, DEHP can be leach from the plastic to transfer the external environment and thus enters the animal food chain, causing serious damage to the animal organs. The heat-shock response (HSR) comprising heat-shock protein (HSPs) and heat-shock transcription factor (HSFs) plays a pivotal role in various toxic stress conditions. For the sake of investigating the effects of DEHP exposure on cardiac toxicity and the regulation of HSR, male quail were fed the diet with 0, 250, 500 and 750 mg/kg DEHP by gavage administration for 45 days. Histopathological changes including cardiomyocyte swelling and muscle fiber dilatation were observed in the hearts exposed to DEHP. During the DEHP treatment, the mRNA expression of HSP60 and HSP70 were universally reduced, while the expression of other HSPs (HSP10, HSP25, HSP27, HSP40, HSP47, HSP90, HSP110) had different degrees of growth. In addition, the levels of HSF1, HSF2, and HSF3 were significantly increased. Given the facts above, DEHP exposure induced the toxic effects of quail heart. DEHP exposure did great harm to HSR via affecting the synthesis of HSFs to mediate the transcription of the HSPs. Ultimately, this study provided new evidence that DEHP induced cardiotoxicity in quail was related to activation of HSR and playing a protective role. PMID- 30300840 TI - Adsorption of phenolic compounds from water by a novel ethylenediamine rosin based resin: Interaction models and adsorption mechanisms. AB - This study describes the adsorption performance of a novel ethylenediamine rosin based resin (EDAR) for several industrially-important phenolic compounds. Its removal of 4-nitrophenol (4-NP) from water was comparable to or better than many commercial resins, although it was less effective with other phenols (i. e., phenol, 2,4-dichlorophenol, 4-chlorophenol, and 4-methylphenol). Experimental conditions for batch adsorption of 4-NP by EDAR are evaluated, the adsorption kinetics is well described by the pseudo-second-order model (R2 > 0.99) and isotherm follows the Langmuir isotherm model (R2 > 0.99), with the maximum monolayer adsorption capacity of 82 mg g-1 at pH 6.0 and 293 K. The thermodynamic parameters indicate that the adsorption is spontaneous and endothermic. Also, quantum chemistry calculations indicate involvement of hydrogen-bonding between 4 NP and amino groups of EDAR. 4-NP was efficiently desorbed from the loaded EDAR resin by 0.2 M HCl, and the resin could be recycled with only a small decrease in its initial adsorption capacities. Thus, EDAR is a promising adsorbent for the removal of 4-NP during water treatment. PMID- 30300841 TI - Harmful effect of nanoparticles on the functions of freshwater ecosystems: Insight into nanoZnO-polluted stream. AB - ZnO nanoparticle toxicity on aquatic organisms has been extensively studied, but its concentration-and time-dependent effects on ecosystem functioning are remain uncertain. Here we assessed the harmful effects of nano-ZnO (10, 100, 1000 mg L 1) on the stream functioning by using a microcosm system simulating poplar leaf decomposition for 50 days. The 100 mg L-1 ZnO nanoparticles had significantly and stably inhibitory effect on the litter decomposition during the exposure period. The inhibition was not detected in the 10 mg L-1 treatment until 43 d. In contrast, the significant and continuous inhibition started to disappear from 43 d in the 1000 mg L-1 treatment. The varied consequences on litter decomposition might be directly affected by the different ZnO nanoparticle homogeneity of the different treatments. ZnO nanoparticles led to significant decreases in pH value of the decomposition environment, which had significant and positive relationships to the activities of dehydrogenase, glycine-aminopeptidase, N acetylglucosaminidase, and acid phosphatase. Besides, 10 and 1000 mg L-1 ZnO nanoparticles led to lower fungal diversity, which was negatively related to the variability of decomposition. In conclusion, fungal decomposers showed different responses to the different concentrations of ZnO nanoparticle, and ultimately affected the stability of ecosystem functions. PMID- 30300842 TI - Does early object exploration support gesture and language development in extremely preterm infants and full-term infants? AB - BACKGROUND: An increasing body of research on typically and atypically developing infants has shown that motor skills play an important role in language development. To date, however, the role of specific object exploration skills for early gesture and vocabulary development has not been investigated in extremely low gestational age infants (ELGA, GA < 28 weeks), who are at greater risk for motor and language delays than full-term (FT) infants. PURPOSE: This longitudinal study examined relations between 6-month active exploratory behaviors and 12- month word comprehension, gestures and vocal production, controlling for cognitive performance and neonatal condition (ELGA vs FT). METHODS: Forty infants, 20 ELGA and 20 FT, and their mothers participated in the study. Mother infant play interaction was video-recorded at 6 and 12 months. Oral and manual object exploration at 6 months and spontaneous gestures and vocal production at 12 months were coded. Word comprehension was evaluated with the Italian version of the MacArthur-Bates CDI parent questionnaire at 12 months. Cognitive performance was examined with the Griffiths Mental Developmental Scales at 6 months and the Bayley-III Scales at 12 months. RESULTS: Regression analyses showed that after accounting for cognitive performance and neonatal condition, oral exploration was related to word comprehension, and manual exploration to gestures and vocal production in the overall sample. CONCLUSIONS: Cascading effects of specific object exploration skills on gestures and language comprehension and production in preterm infants and FT infants are discussed. Clinical implications for early assessment of and interventions involving object exploration skills, which may affect language development, are considered for the preterm population. PMID- 30300843 TI - Structural exploration of cinnamate-based phosphonic acids as inhibitors of bacterial ureases. AB - The conjugated system of cinnamic acid, alpha-substituted with a phosphonoalkyl residue, was previously validated as a scaffold that provided one of the most potent organophosphorus inhibitors of bacterial urease. Following the idea of using Morita-Baylis-Hillman adducts to introduce the terminal phosphonic side chain functionality to the alpha,beta-unsaturated system, we currently report the synthesis and activity of an extended series of compounds. Cinnamates modified with 3-phosphonopropyl and 4-phosphonobutyl side chains were obtained in a convenient two-step procedure, which involved Pd-mediated transformations of the Morita-Baylis-Hillman bromides as the key substrates. The introduction of a terminal alkenyl fragment, which was achieved by Stille coupling with stannanes, was followed by a tandem C-P bond formation/oxidation process. A submicromolar ligand of Sporosarcina pasteurii urease (Ki = 0.509 MUM) was identified among the active molecules. In addition, inhibitors of Proteus mirabilis urease affected bacterial growth at the micromolar level. Based on the structure-activity relationship and the mechanism of inhibition, we suggest a nontypical mixed mode of action for the slow binding compounds. We presume that the molecular distance between the phosphonic group and the backbone double bond allows a dual activity: complexation of the acidic group with nickel ions and Michael addition of a cysteine forming the active site lid. PMID- 30300844 TI - Designing dichlorobinaphthoquinone as a prooxidative anticancer agent based on hydrogen peroxide-responsive in situ production of hydroxyl radicals. AB - Compared with normal cells, cancer cells harbor increased levels of reactive oxygen species (ROS) including hydrogen peroxide (H2O2), and therefore are more vulnerable to further ROS production. This biochemical difference favors the idea of developing new powerful selective prooxidative anticancer agents. However, it still remains a challenge to design them by targeting this difference. Herein, we report the designed dichlorobinaphthoquinone as a prooxidative anticancer agent which is capable of exploiting increased levels of H2O2 of cancer cells to produce in situ lethal hydroxyl radicals (HO*) and thereby kill them selectively, a design strategy inspired from Zhu et al.'s work on the molecular mechanism for metal-independent production of HO*. PMID- 30300845 TI - 1-(2-Hydroxybenzoyl)-thiosemicarbazides are promising antimicrobial agents targeting d-alanine-d-alanine ligase in bacterio. AB - The bacterial cell wall and the enzymes involved in peptidoglycan synthesis are privileged targets for the development of novel antibacterial agents. In this work, a series of 1-(2-hydroxybenzoyl)-thiosemicarbazides inhibitors of D-Ala-D Ala ligase (Ddl) were designed and synthesized in order to target resistant strains of bacteria. Among these, the 4-(3,4-dichlorophenyl)-1-(2-hydroxybenzoyl) 3-thiosemicarbazide 29 was identified as a potent Ddl inhibitor with activity in the micromolar range. This compound, possessing strong antimicrobial activity including against multidrug resistant strains, was proven to act through a bactericidal mechanism and demonstrated very low cytotoxicity on THP-1 human monocytic cell line. Inhibition of Ddl activity by 29 was confirmed in bacterio using UPLC-MS/MS by demonstrating an increase in D-Ala intracellular pools accompanied by a commensurate decrease in D-Ala-D-Ala. Further structure-activity relationships (SARs) studies provided evidence that the hydroxyl substituent in the 2-position (R1) of the benzoylthiosemicarbazide scaffold is essential for the enzymatic inhibition. This work thus highlights the 1-(2-hydroxybenzoyl) thiosemicarbazide motif as a very promising tool for the development of novel antibacterial compounds acting through an interesting mechanism of action and low cytotoxicity. PMID- 30300846 TI - Using summary videos in online classes for nursing students: A mixed methods study. AB - Online courses need strategies to engage students, especially after a learning module is over. We made a series of summary videos for students' assignments and investigated their impact on students' learning. This study investigated whether, from the students' perspective, summary videos made by teachers for each learning module in asynchronized online courses led to students' engagement and feeling of being helped. We used exploratory sequential mixed methods research design, which started with a qualitative phase. After collecting students' feedback from an open-ended question administered to 47 nursing students from 3 online courses, we conducted qualitative data analysis. The analysis identified 2 themes: engagement and helpfulness. We used these themes to find 2 validated surveys from the literature to quantitatively measure students' engagement levels and perceived helpfulness of the summary videos. In the quantitative phase, we surveyed 78 nursing students from 4 online courses 3 times. The results indicated that there was no statistically significant difference in students' perceived engagement level among the 3 time points, and that students did not believe the helpful impact of the summary videos on their learning increased significantly. In the mixed methods phase, we compared and contrasted the teaching strategies, quotes from the qualitative strand, and results from the statistical analyses of survey data. The results indicated that the summary videos were helpful in facilitating students' achievement of learning new knowledge and reinforcing previous knowledge; engaging students cognitively, emotionally, and socially; and motivating students intrinsically. However, the videos did not help with students' behavioral engagement and did not help students have a fun learning experience. We concluded that the teaching presence in the summary videos created the positive and supportive learning environment necessary for giving students the opportunity to engage with learning contents. PMID- 30300847 TI - Recovery of failing hearts by mechanical unloading: Pathophysiologic insights and clinical relevance. AB - By reduction of ventricular wall-tension and improving the blood supply to vital organs, ventricular assist devices (VADs) can eliminate the major pathophysiological stimuli for cardiac remodeling and even induce reverse remodeling occasionally accompanied by clinically relevant reversal of cardiac structural and functional alterations allowing VAD explantation, even if the underlying cause for the heart failure (HF) was dilated cardiomyopathy. Accordingly, a tempting potential indication for VADs in the future might be their elective implantation as a therapeutic strategy to promote cardiac recovery in earlier stages of HF, when the reversibility of morphological and functional alterations is higher. However, the low probability of clinically relevant cardiac improvement after VAD implantation and the lack of criteria which can predict recovery already before VAD implantation do not allow so far VAD implantations primarily designed as a bridge to cardiac recovery. The few investigations regarding myocardial reverse remodeling at cellular and sub cellular level in recovered patients who underwent VAD explantation, the differences in HF etiology and pre-implant duration of HF in recovered patients and also the differences in medical therapy used by different institutions during VAD support make it currently impossible to understand sufficiently all the biological processes and mechanisms involved in cardiac improvement which allows even VAD explantation in some patients. This article aims to provide an overview of the existing knowledge about VAD-promoted cardiac improvement focusing on the importance of bench-to-bedside research which is mandatory for attaining the future goal to use long-term VADs also as therapy-devices for reversal of chronic HF. PMID- 30300848 TI - Concurrence of juvenile idiopathic arthritis and primary demyelinating disease in a young child. AB - CASE REPORT: The association of juvenile idiopathic arthritis (JIA) and primary demyelinating disease of central nervous system (CNS) in the same patient is rare. Here we present a 10-year-old girl formerly diagnosed with JIA who presented with acute total vision loss. Magnetic resonance imaging of the brain and spinal cord showed bilateral optic neuritis and T2 hyperintense lesions in the brain, cerebellum and cervical spinal cord, some of them gadolinium enhancing. Oligoclonal bands were present in the cerebrospinal fluid. Visual evoked potentials were prolonged. Aquaporin-4 antibodies were negative. The patient was treated with methylprednisolone 30 mg/kg daily for five days, resulting in improvement in vision and gait. This first demyelinating event in this patient with JIA with clinical and paraclinical features meeting the 2017 MS diagnostic criteria supports a possible predisposition to autoimmune disorders. CONCLUSION: The concurrence of JIA and multiple sclerosis (MS) has been reported in only two adult cases and not in the pediatric population. While JIA and MS are two distinct chronic inflammatory diseases, immunogenetic predisposition and common environmental triggers might be involved. PMID- 30300849 TI - Cardiorespiratory fitness and cognitive processing speed in multiple sclerosis: The possible roles of psychological symptoms. AB - BACKGROUND: Aerobic exercise training may improve cognitive performance among persons with multiple sclerosis (MS). This is largely based on evidence that cardiorespiratory fitness (as a cross-sectional surrogate for aerobic exercise training) is associated with cognitive processing speed. There may be a set of "other" variables (i.e., psychological symptoms) that influences the association between cardiorespiratory fitness and cognitive processing speed in MS, and such factors should be accounted for when designing optimized exercise rehabilitation interventions. METHODS: The primary objective of the present study involved examining psychological symptoms of anxiety, depression, pain, and fatigue as possible mediators, moderators, or confounders of the association between cardiorespiratory fitness and cognitive processing speed. Sixty-two persons across the MS disability spectrum completed anxiety, depression, pain, and fatigue questionnaires; underwent Symbol Digit Modalities Test administration; as well as two separate incremental exercise tests to exhaustion for measurement of psychological symptoms, cognitive processing speed, and cardiorespiratory fitness, respectively. RESULTS: Depressive symptoms, pain, and fatigue were significantly and jointly associated with cardiorespiratory fitness and cognitive processing speed (p < .05) based on bivariate correlation analyses. Despite those associations, hierarchical linear regression, bivariate correlation, and partial correlation analyses indicated that those psychological symptoms were not mediators, moderators, or confounders of the cardiorespiratory fitness/cognitive processing speed relationship, respectively. CONCLUSION: The present pattern of results suggests that aerobic exercise training (via improving cardiorespiratory fitness) might improve cognitive processing speed independent of the influence of depression, pain, and fatigue. Such results further suggest that having elevated depressive symptoms or severe MS-related fatigue might not affect aerobic exercise training-related changes in cognitive processing speed, and that psychological symptoms might not distort the association between aerobic exercise training and changes in cognitive processing speed. PMID- 30300850 TI - Atypical Anti-MOG syndrome with aseptic meningoencephalitis and pseudotumor cerebri-like presentations. AB - OBJECTIVE: To describe 2 atypical cases with Anti-MOG antibody related demyelinating syndrome. METHODOLOGY: Case series. RESULTS: We present two cases. Case 1 is an 18-year-old woman who presented with headache, blurred vision, and papilledema and was initially diagnosed with pseudotumor cerebri syndrome. CSF showed mildly elevated opening pressure and lymphocytic pleocytosis and a diagnosis of aseptic meningitis was considered. MRI brain and spinal cord revealed longitudinally extensive bilateral simultaneous optic neuritis and multiple spinal cord lesions. Case 2 is a 28-year old man who presented initially with unilateral optic neuritis followed by aseptic meningitis three weeks later and subsequently acute disseminated encephalomyelitis (ADEM). Serology was positive for Anti-MOG antibody on a cell-based assay in both these cases. DISCUSSION: Although bilateral optic neuritis has been well described in MOG related disorders, aseptic meningitis and pseudotumor cerebri-like syndromes are notable alternate presentations. The presence of eosinophils in the CSF (in the first patient) is a unique finding in our case series. CONCLUSION: In a patient with an aseptic meningitis like presentation, the presence of optic neuritis, brain and/or spinal cord lesions should raise suspicion for an MOG-Ab related syndrome.

AB - BACKGROUND: Neuromyelitis optica spectrum disorders (NMOSD) are a spectrum of neuroinflammatory disorders associated with autoimmune antibodies against aquaporin-4 (AQP4). Accumulating evidence suggests that inflammation is involved in NMOSD pathogenesis. Resolution of inflammation, which is a highly regulated process mediated by specialized pro-resolving lipid mediators (SPMs) is important to prevent over-responsive inflammation. Deficiency in resolution of inflammation may lead to or accelerates inflammatory diseases. However, whether resolution of inflammation is impaired in NMOSD is not known. The objective of this study was to analyze the levels of SPMs in the serum and cerebrospinal fluid (CSF) of NMOSD patients, and to explore the roles of SPMs in clinical features of NMOSD. METHODS: Thirty-five patients with NMOSD, 34 patients with multiple sclerosis, and 36 patients with non-inflammatory neurological diseases were enrolled in this study. Pro-resolving mediators including Annexin A1 (ANXA1) and resolvin D1 (RvD1), as well as pro-inflammatory lipid mediator leukotriene B4 (LTB4) levels were analyzed by enzyme-linked immunosorbent assay. Pro- and anti-inflammatory cytokines as well as chemokine levels were analyzed using cytometric beads array (CBA). RESULTS: Our results showed RvD1 levels were significantly decreased, whereas LTB4 levels were significantly increased in the CSF of NMOSD patients. AQP4-IgG titer was negatively correlated with RvD1 levels in the CSF of NMOSD patients. CONCLUSIONS: Decreased RvD1 levels indicate impaired resolution of inflammation in NMOSD patients. AQP4-IgG may contribute to increased inflammation and lead to unresolved inflammation in NMOSD. PMID- 30300853 TI - Protection efficacy of Argentinian isolates of Mycobacterium avium subsp. paratuberculosis with different genotypes and virulence in a murine model. AB - Paratuberculosis is a chronic disease caused by Mycobacterium avium subsp. paratuberculosis (Map). The disease causes economic losses and, therefore, it is imperative to follow proper control strategies, which should include an effective vaccine. Several strategies have assessed the virulence and immune response of Map strains that could be used as a vaccine. This study evaluates the degree of virulence, immune response, and protection of Argentinian strains of Map with different genotype in a murine model. Four local isolates (Cattle type) with different genotypes (analyzed by MIRU-VNTR and SSRs) were selected and evaluated in a virulence assay in BALB/c mice. This assay allowed us to differentiate virulent and low-virulence Map strains. The less virulent strains (1543/481 and A162) failed to induce a significant production of the proinflammatory cytokine IFNg, whereas the virulent strain 6611 established infection along with a proinflammatory immune response. On the other hand, the virulent strain 1347/498 was efficient in establishing a persistent infection, but failed to promote an important Th1 response compared with 6611 at the evaluated time. We selected the low-virulence strain 1543/498 as a live vaccine and the virulent strain 6611 as a live and inactivated vaccine in a protection assay in mice. Strain 1543/481 failed to protect the animals from challenge, whereas strain 6611, in its live and inactivated form, significantly reduced the CFUs count in the infected mice, although they had different immunological response profiles. The inactivated virulent strain 6611 is a potential vaccine candidate against paratuberculosis to be tested in cattle. PMID- 30300854 TI - Inflammation and coronary artery disease: The exercise paradox. PMID- 30300855 TI - Distinct mechanisms regulate IL1B gene transcription in lymphoid CD4 T cells and monocytes. AB - Interleukin 1beta is a pro-inflammatory cytokine important for both normal immune responses and chronic inflammatory diseases. The regulation of the 31 kDa proIL 1beta precursor coded by the IL1B gene has been extensively studied in myeloid cells, but not in lymphoid-derived CD4 T cells. Surprisingly, we found that some CD4 T cell subsets express higher levels of proIL-1beta than unstimulated monocytes, despite relatively low IL1B mRNA levels. We observed a significant increase in IL1B transcription and translation in CD4 T cells upon ex vivo CD3/CD28 activation, and a similar elevation in the CCR5+ effector memory population compared to CCR5- T cells in vivo. The rapid and vigorous increase in IL1B gene transcription for stimulated monocytes has previously been associated with the presence of Spi-1/PU.1 (Spi1), a myeloid-lineage transcription factor, pre-bound to the promoter. In the case of CD4 T cells, this increase occurred despite the lack of detectable Spi1 at the IL1B promoter. Additionally, we found altered epigenetic regulation of the IL1B locus in CD3/CD28-activated CD4 T cells. Unlike monocytes, activated CD4 T cells possess bivalent H3K4me3+/H3K27me3+ nucleosome marks at the IL1B promoter, reflecting low transcriptional activity. These results support a model in which the IL1B gene in CD4 T cells is transcribed from a low-activity bivalent promoter independent of Spi1. Accumulated cytoplasmic proIL-1beta may ultimately be cleaved to mature 17 kDa bioactive IL-1beta, regulating T cell polarization and pathogenic chronic inflammation. PMID- 30300856 TI - Long-term outcome and necessity of liver transplantation in infants with biliary atresia are independent of cytokine milieu in native liver and serum. AB - PURPOSE: Biliary atresia (BA) is a rare disease of unknown pathogenesis in infants characterized by an inflammatory, progressive destruction of the biliary system and deterioration of liver function. The standard treatment for BA is a Kasai-hepatoportoenterostomy (KPE). However, liver transplantation (LTX) becomes necessary in about 50-80% of cases. Therefore, some authors advocate for primary LTX in BA, but this would require early markers to predict which children would benefit from KPE or to show rapid progression to liver cirrhosis (RLC) instead. METHODS: Snap-frozen liver biopsies and sera samples of 57 infants with BA were collected during KPE. Clinical and follow-up data were assessed via the biliary atresia and related diseases registry (BARD-online.com). Protein-levels of 25 pro and anti-inflammatory mediators of 49 infants were assessed via multiplex protein-immunoassay and analyzed by t-test as well as multidimensional principal component analysis. RESULTS: 22 different immunomodulatory mediators were detectable in livers of children with BA, while serum protein levels were very low to undetectable. Following KPE, 33 BA patients showed RLC that required early LTX, while 24 had favorable course of disease with long-term survival with native liver (SNL). There were no significant differences between RLC and SNL in terms of local (from liver samples) nor systemic (from sera) immunomodulatory mediators. Protein levels were much lower in sera than in livers without statistical correlation. CONCLUSION: Our data suggest that local or systemic immunomodulatory mediators are unsuitable for predicting the disease course of BA. Thus, no deduction for optimal treatment strategy can be drawn. Collectively, we conclude that in BA, the degree of inflammation and protein microenvironment in the liver at the time-point of KPE are dismissible factors for the future course of disease. PMID- 30300857 TI - Recruiting, integrating, and sustaining stakeholder participation in environmental management: A case study from the Great Lakes Areas of Concern. AB - Stakeholder participation is now widely viewed as an essential component of environmental management projects, but limited research investigates how practitioners perceive the major challenges and strategies for implementing high quality participation. In order to address this gap, we present findings from a survey and interviews conducted with managers and advisory committee leaders in a case study of United States and binational (US and Canada) Great Lakes Areas of Concern. Our findings suggest that recruiting and integrating participants and sustaining participation over the long term present distinctive ongoing challenges that are not fully recognized in existing conceptualizations of the process of implementing participation. For example, it can be difficult to recruit active stakeholders to fill vacant "slots," to integrate distinctive interests and perspectives in decision-making processes, and to keep participants involved when activity is low and less visible. We present strategies that emerged in the survey and interviews for addressing these challenges, emphasizing the building and leveraging of relationships among stakeholders themselves. Such strategies include balancing tight networks with an openness to new members, supplementing formal hearings with social gatherings, making participation socially meaningful, and dividing labor between managers and advisory committees. PMID- 30300858 TI - Potential development of Irish agricultural sustainability indicators for current and future policy evaluation needs. AB - There is a significant and detailed range of sustainability indicators for Irish agri-food production, but there remain areas where further indicator development or new indicators could prove valuable. This review provides an outline of potential developments in Irish assessment of agricultural sustainability following the latest research and in order to meet policy demands. Recent research findings have suggested means of improved quantitative modelling of greenhouse gas emissions, but additional dietary and soil data may be important for this, especially for the potential inclusion of any soil sequestration. This information could also benefit more detailed modelling of nutrient losses to water. Specific concerns over pesticide and antibiotic use may require additional survey work on the particular locations or types of farms of interest. Biodiversity monitoring could be improved by expanding the range of results oriented agri-environment schemes or employing remote-sensing habitat monitoring, likely supplemented with targeted field surveys for specific objectives. Farm level economic sustainability is largely well-covered, but additional data collection may be of benefit to address specific issues such as labour costs. Recent additional surveys on farm-level social sustainability have addressed important social indicators of isolation and access to local services, and could be rolled out on a larger number of farms in the future. Wider societal concerns such as animal welfare, genetically modified materials in foodstuffs and antibiotic resistance have limited indicators currently available, and could also benefit from additional surveys. The breadth and detail required in agri-food sustainability indicators present a significant challenge to survey design and implementation, but many developments can be achieved without additional surveys through the use of remote sensing and geospatial technologies and integration of existing datasets. Despite the important benefits of further developments in Irish sustainability indicators, consideration must also be given to farmer confidentiality and survey fatigue. PMID- 30300859 TI - Biochar amendment and water stress alter rhizosphere carbon and nitrogen budgets in bauxite-processing residue sand under rehabilitation. AB - Nitrogen (N) bioavailability is one of the main limiting factors for microbial activity and vegetation establishment in bauxite-processing residue sand (BRS). Although beneficial effects of biochar on reducing N loss in the early stages of BRS rehabilitation have been observed previously, the underlying mechanisms of this complicated process, particularly the interactions between applied biochar and the plant rhizosphere is largely unknown. This glasshouse study (116 days), investigated the coupled effects of biochar and water stress on N bioavailability in the rhizosphere of ryegrass (Lolium rigidum) grown in BRS amended with di ammonium phosphate (DAP) fertiliser (at rates of 0 or 2.7 t ha-1) with and without biochar amendment. The applied biochar was characterised as either aged acidic (AC) or alkaline pine (PC) and was mixed with BRS at a rate of 5% v/v under four moisture regimes (50%, 40%, 20% and 7.5% water holding capacity). Amending BRS with AC and PC biochars increased NH4+ retention and decreased cumulative NH3 volatilization within both the rhizosphere and root-free zones compared with fertiliser only treatment. These effects were more pronounced for the AC than PC biochar, suggesting that aged acidic biochar has the great potential for use in rapid establishment of vegetation in BRS disposal areas. The biochar amendment increased cumulative nitrous oxide emissions compared with DAP only treatment, with no significant differences among different moisture regimes. The Control and 20% water holding capacity (WHC) treatment showed the highest dissolved organic carbon (DOC) concentrations compared with other treatments and moisture regimes in the ryegrass rhizosphere, while the highest dissolved organic N concentration were observed in the DAP + AC treatment. Reducing moisture levels below 20% WHC generally decreased microbial biomass carbon (MBC) concentrations and activity in both the rhizosphere and root-free zones of all treatments, while total N generally decreased as moisture levels decreased from 50% to 7.5% WHC. Plant took up more N in the DAP + AC treatment compared with DAP + PC and DAP only treatments, while increasing water stress generally resulted in decreased aboveground biomass. PMID- 30300860 TI - High resolution spectroscopy on Te2: New lines for reference. AB - Ro-vibrational spectra of different electronic states of molecules are often used as absolute wavelength or frequency standards. These standards are also used to mitigate any slow drift of laser frequency during an experiment. In the precision experiment, the two most commonly used molecular standards are iodine and tellurium, both are homo-nuclear diatomic molecules. The former is mostly used as standard for the long wavelength (600-900 nm) region, while the tellurium spectrum is widely used in short wavelength (400-550 nm) including near ultraviolet. A comprehensive data on tellurium spectra can be obtained from the tellurium atlas [1]. However near the 455 nm range where a number of important atomic resonance line, the atlas provides no significant data. We have performed high resolution modulation transfer spectroscopy (MTS) on tellurium molecule in a hot cell in the region close to 455 nm wavelength thereby obtained more than 100 new spectral lines which were not observed before. The linewidth of each of these peaks is about a few tens of MHz, making them suitable for laser frequency locking. PMID- 30300861 TI - Design and optimization of a luminescent Samarium complex of isoprenaline: A chemometric approach based on Factorial design and Box-Behnken response surface methodology. AB - A chemometrically optimized procedure has been developed for the determination of isoprenaline (ISO) in the parent substance as well as in its respective pharmaceutical preparation. It is worth mentioning that although spectroscopic determination of Isoprenaline metal complexes has been described in literature, yet, no methods for the quantification of Isoprenaline with Samarium nor any other lanthanide metal have been reported. Fractional factorial design (FFD) was implemented in the initial screening procedure of the four designated factors, namely, reaction time (RT), metal volume (MV), pH and temperature (T) followed by Response Surface Methodology (RSM) optimization tool performed by the aid of Box Behnken design (BBD).The proposed techniques are based on a multivariate approach where a complexation reaction between Isoprenaline (ISO) and Samarium III (Sm3+) metal was exploited for the first time to synthesize novel fluorescence and absorbance probes of ISO-Sm. Maximum fluorescence intensity (Y1) as well as maximum absorbance (Y2) of the produced complex were attained at lambdaex/lambdaem = 315/450 and lambda 295 nm for spectrofluorimetric and spectrophotometric determinations, respectively, against blank solutions. Using assessment quality tools such as, Pareto charts, normal probability plots and statistical analysis of variance testing (ANOVA), significant factors were successfully indicated (p < 0.05). Furthermore, the proposed methods verified specificity and accuracy for the determination of Isoprenaline in its pure and pharmaceutical preparation using spectrofluorimetric (Technique A) and spectrophotometric (Technique B) techniques, respectively. Linearity was obtained in the range of (0.02-0.50 MUg/mL) and (2-12 MUg/mL) upon employing both techniques A and B, respectively. Furthermore, limit of detection (LOD) and limit of quantification (LOQ), were found to be 5.1877 * 10-3 MUg/mL, 0.01572 MUg/mL and 0.5593 MUg/mL, 1.6949 MUg/mL, upon employing techniques A and B, respectively. Standard addition method was applied for both techniques. The analysis was successfully applied to the assay of pure powder and pharmaceutical dosage forms after which the corresponding mean recoveries were computed and were found to be in the range of 99.546%-100.257% (Technique A) and 99.872%-99.887% (Technique B) with RSD (<1). PMID- 30300863 TI - Effect of nonpharmacological interventions for the prevention of delirium in the intensive care unit: A systematic review and meta-analysis. AB - PURPOSE: We aimed to classify nonpharmacological interventions used for preventing delirium in the intensive care unit (ICU), and estimate their effect size. MATERIALS AND METHODS: In this systematic review and meta-analysis, the literature was searched and studies were selected based on the PRISMA flow chart. Data sources included MEDLINE, Cochrane, CINHAHL, PsyInfo, and EMBASE. We used Cochrane's Effective Practice and Organisation of Care (EPOC) criteria in study design and quality assessment of the meta-analysis. RESULTS: This systematic review and meta-analysis included 35 and 15 studies, respectively. Studies were grouped into nine intervention types: multicomponent (16 studies), physical environment (9), daily interruption of sedation (2), exercise (2), patient education (2), automatic warning system (1), cerebral hemodynamics improving (1), family participation (1), and sedation reducing protocol (1). The effect size of preventive nonpharmacological interventions had an odds ratio (OR) of 0.66 (95% confidence interval [CI], 0.50-0.86) for delirium occurrence, and an OR of 0.31 (95% CI, 0.10-0.94) for delirium duration. Although relevant studies by interventions were lacking, a partial subgroup analysis by intervention was performed. CONCLUSIONS: Nonpharmacological interventions were effective in reducing the duration and occurrence of delirium. Consistent application and development of nonpharmacological interventions for use in the ICU are important. PMID- 30300862 TI - Apoptosis inducing factor deficiency causes retinal photoreceptor degeneration. The protective role of the redox compound methylene blue. AB - Dysfunction in mitochondrial oxidative phosphorylation (OXPHOS) underlies a wide spectrum of human ailments known as mitochondrial diseases. Deficiencies in complex I of the electron transport chain (ETC) contribute to 30-40% of all cases of mitochondrial diseases, and leads to eye disease including optic nerve atrophy and retinal degeneration. The mechanisms responsible for organ damage in mitochondrial defects may include energy deficit, oxidative stress, and an increase in the NADH/NAD+ redox ratio due to decreased NAD+ regeneration. Currently, there is no effective treatment to alleviate human disease induced by complex I defect. Photoreceptor cells have the highest energy demand and dependence on OXPHOS for survival, and the lowest reserve capacity indicating that they are sensitive to OXPHOS defects. We investigated the effect of mitochondrial OXPHOS deficiency on retinal photoreceptors in a model of mitochondrial complex I defect (apoptosis inducing factor, AIF-deficient mice, Harlequin mice), and tested the protective effect of a mitochondrial redox compound (methylene blue, MB) on mitochondrial and photoreceptor integrity. MB prevented the reduction in the retinal thickness and protein markers for photoreceptor outer segments, Muller and ganglion cells, and altered mitochondrial integrity and function induced by AIF deficiency. In rotenone induced complex I deficient 661 W cells (an immortalized mouse photoreceptor cell line) MB decreased the NADH/NAD+ ratio and oxidative stress without correcting the energy deficit, and improved cell survival. MB deactivated the mitochondrial stress response pathways, the unfolding protein response and mitophagy. In conclusion, preserving mitochondrial structure and function alleviates retinal photoreceptor degeneration in mitochondrial complex I defect. PMID- 30300864 TI - A method to quantify intracellular glycation in dermal fibroblasts using liquid chromatography coupled to fluorescence detection - Application to the selection of deglycation compounds of dermatological interest. AB - Glycation is a common non-enzymatic reaction between proteins and sugars, which gives rise in the human body to the formation of advanced glycation end products (AGEs). These modifications impacts both extra and intracellular proteins, leading to cells and tissues dysfunctions. In the skin, accumulation of AGEs leads to aesthetic consequences, wrinkles, dark spots and yellowish skin tone, as it can be seen in diabetic patients. Consequently, there is a growing dermatological interest to find compounds able to eliminate AGEs accumulated in skin. In this context, a method has been developed to detect and quantify intracellular glycation in human dermal fibroblasts. After cultivation of fibroblasts, cell lysates were injected in an HPLC system coupled with a fluorescence detector in by-pass mode. The system allows the simultaneous measurement of global AGEs and particular pentosidine amounts using two sets of wavelengths in a single run of 1 min. The immunocytochemistry approach was used to valid the HPLC analysis data. The method developed was able to quantify changes in global AGEs and pentosidine content in cells in response to glyoxal treatment. Fibroblasts treated with 500 MUM of glyoxal for 48 h showed a significant 2.3-fold and 2.6-fold increase in the content of AGEs and pentosidine respectively compared to control cells. As an application, a screening of natural extracts have been done and the method allowed identifying extracts able to significantly reduce the amount of pentosidine in fibroblasts (-32%). These extracts act as deglycation agents of interest in the field of dermatology and cosmetology. PMID- 30300865 TI - DNA methylation of the ELOVL2, FHL2, KLF14, C1orf132/MIR29B2C, and TRIM59 genes for age prediction from blood, saliva, and buccal swab samples. AB - Many studies have reported age-associated DNA methylation changes and age predictive models in various tissues and body fluids. Although age-associated DNA methylation changes can be tissue-specific, a multi-tissue age predictor that is applicable to various tissues and body fluids with considerable prediction accuracy might be valuable. In this study, DNA methylation at 5 CpG sites from the ELOVL2, FHL2, KLF14, C1orf132/MIR29B2C, and TRIM59 genes were investigated in 448 samples from blood, saliva, and buccal swabs. A multiplex methylation SNaPshot assay was developed to measure DNA methylation simultaneously at the 5 CpG sites. Among the 5 CpG sites, 3 CpG sites in the ELOVL2, KLF14 and TRIM59 genes demonstrated strong correlation between DNA methylation and age in all 3 sample types. Age prediction models built separately for each sample type using the DNA methylation values at the 5 CpG sites showed high prediction accuracy with a Mean Absolute Deviation from the chronological age (MAD) of 3.478 years in blood, 3.552 years in saliva and 4.293 years in buccal swab samples. A tissue combined model constructed with 300 training samples including 100 samples from each blood, saliva and buccal swab samples demonstrated a very strong correlation between predicted and chronological ages (r = 0.937) and a high prediction accuracy with a MAD of 3.844 years in the 148 independent test set samples of 50 blood, 50 saliva and 48 buccal swab samples. Although more validation might be needed, the tissue-combined model's prediction accuracies in each sample type were very much similar to those obtained from each tissue-specific model. The multiplex methylation SNaPshot assay and the age prediction models in our study would be useful in forensic analysis, which frequently involves DNA from blood, saliva, and buccal swab samples. PMID- 30300866 TI - Attempting to discontinue antipsychotic medication: Withdrawal methods, relapse and success. AB - Few studies explore subjective experiences of attempting to discontinue antipsychotic medication, the withdrawal methods people use, or how their efforts affect their outcomes. People who take antipsychotics for off-label purposes are poorly represented in the literature. This study investigates experiences of attempting to discontinue antipsychotics in a cross-sectional sample and explores potential associations between withdrawal methods, relapse, and success. An anonymous online survey was completed by 105 adults who had taken antipsychotics for any reason and had attempted discontinuation at least once. A mixed methods approach was used to interpret the responses. Just over half (55.2%) described successfully stopping for varying lengths of time. Half (50.5%) reported no current use. People across diagnostic groups reported unwanted withdrawal effects, but these were not universal. Withdrawing gradually across more than one month was positively associated, and relapse was negatively associated with both self-defined successful discontinuation and no current use. Gradual withdrawal was negatively associated with relapse during withdrawal. We conclude it is possible to successfully discontinue antipsychotic medication, relapse during withdrawal presents a major obstacle to successfully stopping AMs, and people who withdraw gradually across more than one month may be more likely to stop and to avoid relapse during withdrawal. PMID- 30300867 TI - Social anhedonia and asociality in psychosis revisited. An experience sampling study. AB - The DSM-5 appended the conceptualization of asociality in psychotic disorders as the manifestation of diminished interest in social interactions, but it also admitted that it might merely be the result of limited opportunities for social interactions. In an effort to investigate this apparent dichotomy, we used experience sampling data from 149 patients with psychotic disorder and 143 controls, and divided their social interactions into those occurring in the context of work and other structured activities that patients have limited access to, and those occurring in the context of unstructured activities such as visits and conversations that both groups can choose relatively more freely. Patients spent significantly smaller proportion of their time in structured social context, but matched the controls in the time spent in unstructured social contexts, and endorsed intact hedonic experience of both social contexts. Moreover, employment and living situation, in addition to the severity of symptoms of avolition, predicted the proportion of time patients spent in structured and unstructured social contexts, supporting the notion that both lifestyle as well as disease-specific factors contribute to real-life social behavior in psychosis. PMID- 30300868 TI - Detection of patients with methamphetamine dependence with cue-elicited heart rate variability in a virtual social environment. AB - In the present study, we developed a methamphetamine (METH)-related virtual social environment to elicit subjective craving and physiological reactivity. Sixty-one male patients who were abstinent from METH use and 45 age-matched healthy males (i.e., normal controls) were recruited. The physiological electrocardiogram (ECG) signals were recorded before (resting-state condition) and during viewing of a METH-cue video in the virtual environment (cue-induced condition). The cue-induced subjective craving was measured with a visual analogue scale (VAS) for patients with METH dependence. The results indicated that the cue-induced condition elicited significant differences in heart rate variability (HRV) between patients with METH dependence and normal controls. The changes of HRV indexes on time domain and non-linear domain from the resting state condition to the cue-induced condition were positively correlated with the score on VAS of METH craving. Using a supervised machine learning algorithm with the features extracted from HRV changes, our results showed that the discriminant model provided a high predictive power for distinguishing patients with METH dependence from normal controls. Our findings support that immersing subjects with METH dependence in a METH-related virtual social environment can successfully induce physiological reactivity, and cue-induced physiological signal changes may have a potential implication in clinical practice. PMID- 30300869 TI - Body-focused repetitive behaviors: More prevalent than once thought? AB - Body-focused repetitive behaviors (BFRBs), such as hair pulling, skin picking, and nail biting are common habits, but their pathological manifestations have been considered rare. Growing evidence suggests pathological forms of these behaviors can be conceptualized as a class of related disorders. However, few previous studies have examined the collective prevalence of related pathological BFRBs. The current study examined the self-reported prevalence of current (past month) subclinical and pathological BFRBs in a large (n = 4335) sample of college students. The study also examined the chronicity and impact of these behaviors. Results showed that 59.55% of the sample reported occasionally engaging in subclinical BFRBs, and 12.27% met criteria for a pathological BFRB, suggesting these conditions may be quite common. Of the various BFRB topographies, cheek biting was the most common. Both subclinical and pathological BFRBs tended to be chronic (i.e., occurring for longer than 1 year). Although persons with pathological BFRBs were distressed about their behavior, few experienced functional impairment or sought help for the behavior. Implications of these findings for the conceptualization and treatment of body-focused repetitive behaviors are discussed.

This study aimed to evaluate a low cost scalable mindfulness intervention program to improve psychological health and sleep quality among Chinese university students. A randomized controlled trial with 101 university students (mean age 22.30 +/- 2.63, 69.31% female) was conducted. Participants were randomized into 4 groups: Group 1: control group (n = 25), Group 2: mindfulness only group (n = 27), Group 3: mindfulness + plain-text reminder group (n = 24), and Group 4: mindfulness + enhanced text reminder with animal meme group (n = 25).The mindfulness intervention consisted of two in-person guided sessions along with weekly self-guided practice for 7 weeks. The Depression, Anxiety and Stress Scale (DASS-21) and The Pittsburgh Sleep Quality Index (PSQI) were used to measure depression, anxiety, stress, and sleep dysfunction. After the intervention at week 4, compared to controls, completers in group 2, 3 and 4 (n = 42) showed significantly reduced depression (Cohen's d = 0.83), anxiety (Cohen's d = 0.84), and stress (Cohen's d = 0.75), and improved subjective sleep quality (Cohen's d = 2.00), sleep latency (Cohen's d = 0.55), and habitual sleep efficiency (Cohen's d = 0.86). The effect was maintained at week 7. Low-intensity mindfulness interventions might be a useful intervention program in university settings.

AB - This paper describes the expanded English/Spanish version of the Management Information and Decision Support Epilepsy Tool (MINDSET) as well as the methods and findings from a feasibility study conducted from July 2016 through February 2017 with 43 Spanish and English-speaking Hispanic people living with epilepsy (PWE) in Arizona (n = 23) and Texas (n = 20) over two consecutive regular clinic visits. The expansion of MINDSET added goal setting and strategy selection to improve self-management (S-M) in PWE. The previous study tested the feasibility of English MINDSET, which was designed to facilitate the identification and discussion of S-M issues between the patient and healthcare provider (HCP) during a regular clinic visit. Results indicate MINDSET feasibility for use in the following: 1) identifying S-M issues across several domains; 2) selecting and assessing confidence in tailored S-M goals/strategies for improvement; 3) discussing S-M issues/goals/strategies/confidence with a HCP; and 4) creating an action plan (AP) and tracking achievement during regular clinic visits. Across two visits, 80-90% of patients agreed that the revised version of MINDSET was helpful, understandable, trustworthy, promoted careful thinking about management, was of appropriate duration, and would be helpful in future management and communication with HCP. Participating HCPs agreed that MINDSET improved the ease, thoroughness, and accuracy in identifying patient S-M issues and establishing a plan for improvement.

AB - One of the most adopted solutions in developed countries to manage stormwater is detention/retention basins which generate large quantities of sediments that have to be removed regularly. In order to manage them properly, accurate data are needed about their physical and chemical characteristics, particularly on micropollutant concentrations and their associated risk. This work consisted in a two-year sampling of dry sediments from a detention-settling basin. Priority substances, including pesticides, polybrominated diphenyl ethers (PBDE), alkylphenols and bisphenol A (BPA), were monitored. Different sites in the basin bottom were sampled in order to investigate spatial distribution of the contamination. Results show that the increase of the sediment thickness in the basin was heterogeneous with a maximum of 15 cm after two years. Pesticides and PBDE were, if detected, mainly found in low concentrations from 2 ng/g to 286 ng/g. Conversely, alkylphenols and bisphenol A were always quantified at concentrations varying from 6 ng/g to 3400 ng/g. These high levels suggest that these sediments should be managed with precautions. Spatial heterogeneity of alkylphenol ethoxylates and BPA concentrations was observed, with higher contamination of alkylphenol ethoxylates in anaerobic zones and BPA levels correlated with total organic carbon and in a lesser extent to fine particles. PMID- 30300873 TI - Oxidative potential of fine ambient particles in various environments. AB - The oxidative potential (OP) and chemical characteristics of fine particles collected from urban, roadside, rural, and industrial sites in Korea during spring, summer, fall, and winter seasons and an urban site in the Philippines during dry and wet seasons were examined. Significant differences in the OP of fine particles among sites and seasons were found. The industrial site yielded the highest OP activity (both mass and volume-normalized OP) among the sites, suggesting the strongest reactive oxygen species (ROS)-generating capability of industry source-dominant PM2.5. Seasonal data show that OP activities increased during the spring and summer possibly due to increased heavy metals caused by dust events and secondary organic aerosols formed by strong photochemical activity, respectively. The strength of the OP association with the chemical components highlights the influence of organic carbon and transition metals on the OP of ambient fine particles. The two OP assays (dithiothreitol (DTT) and electron spin resonance (ESR)) having different ROS-generating mechanisms were found to have different sensitivities to the chemical components facilitating a complementary analysis of the OP of ambient fine particles. Multiple linear regression model equations (OP as a function of chemical components) which were dependent on the sites were derived. A comparison of the daily OP and hazard index (HI) (the ratio of the measured mass concentration to the reference mass concentration of fine particles) suggests that the HI may not be sufficient to accurately estimate the health effects of fine particles, and a direct or indirect measurement of toxicity such as OP should be required in addition to the concentration level. PMID- 30300874 TI - Dendritic spine loss caused by AlCl3 is associated with inhibition of the Rac 1/cofilin signaling pathway. AB - Aluminum (Al) has neurotoxicity that can result in cognitive dysfunction. Hippocampal dendritic spine loss is a pathological characteristic of cognitive dysfunction. Our previous study reported that Al exposure caused dendritic spine loss in the hippocampus, but the underlying mechanism remains unclear. In this study, rats were orally administered 50, 150 or 450 mg/kg of AlCl3 for 90 days. The dendritic spine density of the CA1 and DG regions was detected by Golgi-Cox staining. The F-actin/G-actin ratio, the expression of drebrin A and the components of the Rac 1/cofilin pathway were measured in the hippocampus. The results obtained showed that AlCl3 caused dendritic spine loss and decreased the F-actin/G-actin ratio. In addition, it was found that AlCl3 downregulated the expression of Rac 1, p-PAK, p-LIMK, p-cofilin and drebrin A and upregulated cofilin expression. Altogether, these results demonstrated that Al inactivated the Rac 1/cofilin pathway by inhibiting the phosphorylation of cofilin and the polymerization of F-actin, resulting in dendritic spine loss in the hippocampus. PMID- 30300875 TI - A rationale for the high limits of quantification of antibiotic resistance genes in soil. AB - The determination of values of abundance of antibiotic resistance genes (ARGs) per mass of soil is extremely useful to assess the potential impacts of relevant sources of antibiotic resistance, such as irrigation with treated wastewater or manure application. Culture-independent methods and, in particular, quantitative PCR (qPCR), have been regarded as suitable approaches for such a purpose. However, it is arguable if these methods are sensitive enough to measure ARGs abundance at levels that may represent a risk for environmental and human health. This study aimed at demonstrating the range of values of ARGs quantification that can be expected based on currently used procedures of DNA extraction and qPCR analyses. The demonstration was based on the use of soil samples spiked with known amounts of wastewater antibiotic resistant bacteria (ARB) (Enterococcus faecalis, Escherichia coli, Acinetobacter johnsonii, or Pseudomonas aeruginosa), harbouring known ARGs, and also on the calculation of expected values determined based on qPCR. The limits of quantification (LOQ) of the ARGs (vanA, qnrS, blaTEM, blaOXA, blaIMP, blaVIM) were observed to be approximately 4 log-units per gram of soil dry weight, irrespective of the type of soil tested. These values were close to the theoretical LOQ values calculated based on currently used DNA extraction methods and qPCR procedures. The observed LOQ values can be considered extremely high to perform an accurate assessment of the impacts of ARGs discharges in soils. A key message is that ARGs accumulation will be noticeable only at very high doses. The assessment of the impacts of ARGs discharges in soils, of associated risks of propagation and potential transmission to humans, must take into consideration this type of evidence, and avoid the simplistic assumption that no detection corresponds to risk absence. PMID- 30300876 TI - Effectiveness End Points in Real-World Studies on Biological Therapies in Psoriasis: Systematic Review with Focus on Drug Survival. AB - Psoriasis is a complex and chronic disease, and, in most cases, therapies are required during all patients' lifetime. The efficacy and safety profiles of biological therapies are well established, but their effectiveness is still open to discussion. We performed a systematic review to summarize how the effectiveness of biological therapies for psoriasis is measured in real-world studies and to understand whether drug survival, a recent alternative outcome to clinical ones, is a recurrent and valid outcome of effectiveness. In March 2017, we searched for quantitative epidemiological data of psoriasis treatments using PubMed/Medline and EMBASE, and we included 65 publications. The retrospective study design (37%) was most frequent, followed by prospective registries (29%), prospective studies (19%), and retrospective administrative databases/claims. Drug survival was reported in over 60% of prospective registries and retrospective studies, and less frequently in prospective studies. A general consensus emerged in the definition of drug survival as the time patients remain under treatment with a specific therapy, and in its interpretation as an overall marker of treatment success and treatment adherence, as it represents simultaneously information on drug efficacy, drug safety, and patient satisfaction. In conclusion, notwithstanding some limitations, drug survival is a useful measurement of biological therapy effectiveness for psoriasis in daily practice. Its major advantage is that it can be computed also in already collected databases without any specific clinical information on psoriasis. This outcome, combined with evidence on clinical markers of effectiveness, can contribute to better understanding the performance of this expensive class of drugs. PMID- 30300877 TI - To Wash or Not to Wash? Comparison of Patient Outcome after Infusion of Cryopreserved Autologous Hematopoietic Stem Cells before and after the Replacement of Manual Washing by Bedside Thawing. AB - BACKGROUND: Prior to infusion, cryopreserved autologous peripheral blood stem cell (auto-PBSC) grafts can either be thawed at the bedside or thawed and washed at the laboratory. At our center, manual washing of grafts prior to infusion was discontinued in April 2012 and bedside thawing was implemented. METHODS: This study compares the outcomes of two patient groups who received auto-PBSC either after post-thaw washing (n = 84) or bedside thawing (n = 83). RESULTS: No life threatening infusion-related side effects were reported in either group. There was no significant difference in the mean CD34+ cells/kg dose of infused auto PBSC in the two groups (p = 0.41), nor in the number of days to neutrophils > 0.5 * 109/L (p = 0.14), days to platelets > 20 * 109/L (p = 0.64), or days to platelets > 50 * 109/L (p = 0.62) after transplant. There was also no difference in the number of days on total parenteral nutrition (p = 0.69), days on G-CSF therapy (p = 0.48), or days with fever (p = 0.73). Finally, there was no significant difference in the number of red cell units transfused (p = 0.32), or platelet units transfused (p = 0.94) after the transplant. One-hundred-day mortality was identical in the two groups (2.4%). CONCLUSION: Both thawing procedures are safe and result in acceptable engraftment and patient outcomes. PMID- 30300878 TI - Balance Control during Stance and Gait after Cochlear Implant Surgery. AB - BACKGROUND: After cochlear implant (CI) surgery, some patients experience vertigo, dizziness and/or deficits in vestibulo-ocular reflexes. However, little is known about the effect of CI surgery on balance control. Therefore, we examined differences in stance and gait balance control before versus after CI surgery. METHODS: Balance control of 30 CI patients (mean age 59, SD 15.4 years), receiving a first unilateral CI surgery, was measured preoperatively and postoperatively 1 month after the initial implant stimulation (2 months after surgery). Trunk sway was measured during 14 stance and gait tests using an angular-velocity system mounted at lumbar vertebrae 1-3. RESULTS: For pre- versus postoperative comparisons across all 30 patients, a nonsignificant worsening in balance control was observed. Significant changes were, however, found within subgroups. Patients younger than 60 years of age had a significant worsening of an overall balance control index (BCI) after CI surgery (p = 0.008), as did patients with a normal BCI preoperatively (p = 0.005). Gait task measures comprising the BCI followed a similar pattern, but stance control was unchanged. In contrast, patients over 60 years or with a pathological BCI preoperatively showed improved tandem walking postoperatively (p = 0.0235). CONCLUSION: Across all CI patients, CI surgery has a minor effect on balance control 2 months postoperatively. However, for patients younger than 60 years and those with normal balance control preoperatively, balance control worsened for gait indicating the need for preoperative counseling. PMID- 30300879 TI - Prognostic Value of Inflammatory Biomarkers in Gastric Cancer Patients and the Construction of a Predictive Model. AB - BACKGROUND: It is known that inflammation promotes cancer development. However, a few studies have evaluated the prognostic significance of inflammatory biomarkers in gastric cancer (GC). METHODS: In this study, 2,334 patients who underwent gastrectomy for GC at Fudan University Shanghai Cancer Center between 2003 and 2007 were retrospectively analyzed, and 1,227 patients were found to be eligible. The preoperative serum neutrophil-to-lymphocyte ratio (NLR), platelet-to lymphocyte ratio, lymphocyte-to-monocyte ratio (LMR), and albumin/globulin ratio (AGR) levels were analyzed. A nomogram was constructed with the Cox proportional hazards regression model in the training set (n = 818) to predict the probability of overall survival (OS) and disease-free survival (DFS). The predictive accuracy and discriminative ability were determined using the concordance index (C-index) and calibration curve. RESULTS: We found that lower AGR and LMR values were correlated with decreased OS, lower LMR values, and higher NLR values with a decreased DFS. Other significant factors were included to construct the nomogram. The discriminative ability of the nomogram was higher than that of the eighth American Joint Committee on Cancer tumor-node-metastasis (TNM) staging system (0.746 for TNM v.s. 0.654 for the nomogram, p < 0.001). CONCLUSIONS: The nomogram yielded a more accurate prognostic prediction in GC patients after gastrectomy, suggesting great clinical value. PMID- 30300880 TI - Association between Type of Residence and Clinical Signs of Neglect in Older Adults. AB - BACKGROUND: Studies have demonstrated that measures of lower quality of care and associated adverse health effects are more prevalent in for-profit nursing homes compared to not-for-profit facilities. However, these studies omit persons who receive care in the community setting, and exclusively focus on isolated clinical signs that may obscure the true effect size, since these clinical signs rarely occur in isolation. OBJECTIVE: In this study, we use the Clinical Signs of Neglect Scale (CSNS), which is an aggregate measure of clinical signs of neglect and substandard care, to evaluate the association of residence type on health outcomes among individuals living in both private community residences and for profit and not-for-profit long-term care facilities. METHODS: In a multicenter, retrospective data analysis of 1,149 patients identified from an inpatient hospital registry, we assessed the relationship between residence type (community dwelling, not-for-profit, and for-profit facilities) and clinical signs of neglect. Adjusted parameter estimates and 95% CIs were estimated with linear regression in 3 models using different reference groups. RESULTS: The most serious clinical signs were consistently more prevalent among residents of for profit facilities, as were measures of poor institutional quality. Relative to low-functioning community-dwelling patients, the mean difference in CSNS scores was higher among patients residing in not-for-profit facilities by 1.99 (p = 0.012) and 3.55 (p <= 0.001) among patients in for-profit facilities. In a separate model, the mean difference in CSNS scores among patients living in for profit facilities compared to not-for-profit facilities was 1.90 (p = 0.035). CONCLUSIONS: Using an aggregate measure, our findings support prior studies demonstrating an association between residence type and adverse health outcomes for disabled elderly.

PMID- 30300882 TI - Cortical Processing of Frequency Changes Reflected by the Acoustic Change Complex in Adult Cochlear Implant Users. AB - The purpose of this study was to examine neural substrates of frequency change detection in cochlear implant (CI) recipients using the acoustic change complex (ACC), a type of cortical auditory evoked potential elicited by acoustic changes in an ongoing stimulus. A psychoacoustic test and electroencephalographic recording were administered in 12 postlingually deafened adult CI users. The stimuli were pure tones containing different magnitudes of upward frequency changes. Results showed that the frequency change detection threshold (FCDT) was 3.79% in the CI users, with a large variability. The ACC N1' latency was significantly correlated with the FCDT and the clinically collected speech perception score. The results suggested that the ACC evoked by frequency changes can serve as a useful objective tool in assessing frequency change detection capability and predicting speech perception performance in CI users. PMID- 30300883 TI - Bone Involvement in Hodgkin's Lymphoma: Clinical Features and Outcome. AB - Hodgkin's lymphoma (HL) is now a highly curable disease, with an improving 5-year survival rate that has now reached 86%. At the time of presentation, HL is usually almost entirely confined to the lymph nodes. We performed a retrospective single-institution study of 384 cases with a median follow-up of 44 months, with the aim of identifying clinical and radiological characteristics and outcomes of patients with bone HL; 32 patients (8%) had primary bone involvement, always with concurrent nodal disease. These included 22 men (69%) and 10 women (31%) with the median age as 41 years. Advanced stages and nodular sclerosis histology prevailed among the subgroup. Radiographic features of bone HL are not specific but indicate a destructive malignant process with osteosclerosis and/or osteolysis. With current chemotherapeutic regimens, the long-term prognosis of patients with osseous HL appears good. The presence of bone lesions in HL should not be interpreted as implying a worse prognosis than without bone involvement. PMID- 30300884 TI - Na+/H+ Exchangers Are Required for the Development and Function of Vertebrate Mucociliary Epithelia. AB - Na+/H+ exchangers (NHEs) represent a highly conserved family of ion transporters that regulate pH homeostasis. NHEs as well as other proton transporters were previously linked to the regulation of the Wnt signaling pathway, cell polarity signaling, and mucociliary function. Furthermore, mutations in the gene SLC9A3 (encoding NHE3) were detected as additional risk factors for airway infections in cystic fibrosis patients. Here, we used the Xenopus embryonic mucociliary epidermis as well as human airway epithelial cells (HAECs) as models to investigate the functional roles of NHEs in mucociliary development and regeneration. In Xenopus embryos, NHEs 1-3 were expressed during epidermal development, and loss of NHE function impaired mucociliary clearance in tadpoles. Clearance defects were caused by reduced cilia formation, disrupted alignment of basal bodies in multiciliated cells (MCCs), and dysregulated mucociliary gene expression. These data also suggested that NHEs may contribute to the activation of Wnt signaling in mucociliary epithelia. In HAECs, pharmacological inhibition of NHE function also caused defective ciliation and regeneration in airway MCCs. Collectively, our data revealed a requirement for NHEs in vertebrate mucociliary epithelia and linked NHE activity to cilia formation and function in differentiating MCCs. Our results provide an entry point for the understanding of the contribution of NHEs to signaling, development, and pathogenesis in the human respiratory tract. PMID- 30300885 TI - Prognostic Accuracy of Heart Rate Variability Analysis in Neonatal Encephalopathy: A Systematic Review. AB - BACKGROUND: Heart rate variability analysis offers real-time quantification of autonomic disturbance after perinatal asphyxia, and may therefore aid in disease stratification and prognostication after neonatal encephalopathy (NE). OBJECTIVE: To systematically review the existing literature on the accuracy of early heart rate variability (HRV) to predict brain injury and adverse neurodevelopmental outcomes after NE. DESIGN/METHODS: We systematically searched the literature published between May 1947 and May 2018. We included all prospective and retrospective studies reporting HRV metrics, within the first 7 days of life in babies with NE, and its association with adverse outcomes (defined as evidence of brain injury on magnetic resonance imaging and/or abnormal neurodevelopment at >=1 year of age). We extracted raw data wherever possible to calculate the prognostic indices with confidence intervals. RESULTS: We retrieved 379 citations, 5 of which met the criteria. One further study was excluded as it analysed an already-included cohort. The 4 studies provided data on 205 babies, 80 (39%) of whom had adverse outcomes. Prognostic accuracy was reported for 12 different HRV metrics and the area under the curve (AUC) varied between 0.79 and 0.94. The best performing metric reported in the included studies was the relative power of high-frequency band, with an AUC of 0.94. CONCLUSIONS: HRV metrics are a promising bedside tool for early prediction of brain injury and neurodevelopmental outcome in babies with NE. Due to the small number of studies available, their heterogeneity and methodological limitations, further research is needed to refine this tool so that it can be used in clinical practice. PMID- 30300886 TI - Different Genetic Expression Profiles of Oxidative Stress and Apoptosis-Related Genes in Crohn's Disease. AB - BACKGROUND/AIMS: Increased oxidative stress and decreased immune cell apoptosis have been reported to be important factors in the pathogenesis of Crohn's disease (CD). Our aim was to characterize the genetic expression of molecules implicated in the regulation of oxidative stress and apoptosis in peripheral white mononuclear cells of 18 healthy volunteers (controls) and 20 patients at the onset of CD (active CD [aCD]): 10 who achieved remission (inactive CD [iCD]) and 10 who did not present a complete and deep response to treatment (aCD-T). METHODS: mRNA expression was measured by the Agena MassARRAY quantitative gene expression analysis application. The genes analyzed were Fas-receptor (FASR), Fas ligand (FASL), signal transducer and activator of transcription 1 (STAT1), nuclear factor kappa-light-chain--enhancer of activated B cells (NFKB1), apoptosis signal-regulating kinase 1 (ASK1), serine/threonine-protein kinase H1 (PSKH1), ATP-binding cassette sub-family B1 (ABCB1) and peptidylprolyl isomerase D (PPID). RESULTS: During a CD flare, we found specific upregulated expression of the genes STAT1 and PSKH1, whereas ABCB1 and FASL were downregulated. In the patients with iCD, FASR and NFKB1 were upregulated. The expression levels of NFKB1, STAT1 and ABCB1 did not show any difference in patients with aCD at the onset of the disease and after treatment (aCD-T). The expression levels of PPID and ASK1 did not show any differences in the patients with aCD, iCD and the controls. We have also reviewed the cellular function and role of these genes in CD. CONCLUSIONS: These findings contribute to improving the understanding of the pathogenesis of CD and highlight potential genes involved. PMID- 30300887 TI - Hyperbaric Oxygen Therapy as Concurrent Treatment with Systemic Steroids for Idiopathic Sudden Sensorineural Hearing Loss: A Comparison of Three Different Steroid Treatments. AB - We analyzed 356 patients with idiopathic sudden sensorineural hearing loss treated with hyperbaric oxygen therapy and systemic steroids (n = 161), systemic steroids alone (n = 160), or intratympanic and systemic steroids (n = 35). The main outcome measure was the hearing recovery rate. The effect of other variables, including the initial averaged 5-frequency hearing level, patient age, interval between the onset of symptoms and treatment, presence of vertigo as a complication, presence of diabetes mellitus, smoking history, and presence of hypertension, on the hearing recovery rate was also evaluated. The overall hearing recovery rate was significantly higher for the patients treated with hyperbaric oxygen therapy and systemic steroids than for those treated with systemic steroids alone (p < 0.001) or systemic and intratympanic steroids (p < 0.001). The presence of vertigo negatively affected hearing recovery. Our findings suggest that hyperbaric oxygen therapy confers a significant additional therapeutic benefit when used in combination with steroid therapy for idiopathic sudden sensorineural hearing loss. PMID- 30300888 TI - [Arzneipflanzen im Berner Pferdestall: Erfahrungswissen von Pferdehaltern]. AB - Hintergrund: Wahrend uber den traditionellen Einsatz von Arzneipflanzen durch Landwirtinnen und Landwirte beim Nutztier sowohl in Sudeuropa als auch in der Schweiz zunehmend wissenschaftliche Veroffentlichungen vorliegen, fehlen gezielte Studien mit Pferdebesitzern weitestgehend. Mit der vorliegenden Studie sollte dieses Wissen exemplarisch fur den Schweizer Kanton Bern erfasst werden. Probanden und Methoden: Methodisch an vorhergehende Studien in der Schweiz angelehnt, wurden von 2011-2012 7 Pferdehalter im Alter von 24-65 Jahren anhand eines semistrukturierten Fragebogens zum Einsatz von Arzneipflanzen bei ihren Pferden interviewt. Neben Informationen zu Pflanzenarten und Pflanzenteilen wurden die Zubereitung und Anwendung (inklusive Dosierung) der Rezepturen detailliert dokumentiert. Ergebnisse: Insgesamt wurden 21 Rezepturen von den Berner Pferdehaltern genannt, von denen 4 Mischungen aus 2-5 verschiedenen Pflanzenarten waren. In den Rezepturen wurden 27 Pflanzenarten aus 22 Pflanzenfamilien verwendet. Fur mehr als 50% der Rezepte wurden die Arzneipflanzen in der Apotheke gekauft, jedoch lediglich fur 1 (4%) beim Tierarzt; fur ein weiteres Drittel der Rezepte wurden Pflanzen gesammelt. Fur die 21 Rezepturen wurden 30 Anwendungen beschrieben, vor allem zur Behandlung der Haut, des Bewegungsapparats und der Atemwege. Am haufigsten wurden Anwendungen von Ingwer (Zingiber officinale) und Johanniskraut (Hypericum perforatum) genannt. Beide Pflanzen werden uberwiegend zur innerlichen (Ingwer) bzw. aubetaerlichen Behandlung (Johanniskrautblutenol) von Erkrankungen des Bewegungsapparats eingesetzt. Schlussfolgerungen: Gemessen an der Zahl der interviewten Pferdehalter kommt im Kanton Bern traditionell ein breites Spektrum von Arzneipflanzen beim Pferd zum Einsatz. Auch wenn Tierarzte aktuell kaum als Bezugsquelle fur Arzneipflanzen dienen, durfte das Potenzial fur die tierarztliche Phytotherapie in der Pferdemedizin grobeta sein.

PMID- 30300890 TI - Can Fetal Umbilical Venous Blood Be a Reliable Source for Admission Complete Blood Count and Culture in NICU Patients? AB - BACKGROUND: Minimizing initial neonatal blood draws and their associated pain is important. The placenta has ample fetal blood that is otherwise discarded; obtaining admission laboratory evaluations from fetal umbilical venous blood (FUVB) may provide a suitable alternative. OBJECTIVE: We hypothesized that obtaining an aerobic bacterial blood culture (BCX) and a complete blood count with manual differential (CBC/diff) from FUVB is feasible and yields results comparable to those obtained directly from the neonate. STUDY DESIGN: BCX and CBC/diff were attempted on paired samples from FUVB (in the delivery room) and neonatal blood (shortly after NICU admission) of 110 patients. The paired t test, Pearson's correlation coefficient (R), and multivariable linear regression were used for data analysis. RESULTS: Positive BCXs were found in 9 of 108 FUVB samples compared to 1 of 91 neonatal samples. Three out of 9 FUVB cultures were true pathogens, including 2 Escherichia coli and 1 viridans group streptococcus, all with negative corresponding paired neonatal cultures. There was 1 positive neonatal BCX, E. coli, with a negative paired FUVB culture. Neonatal hemoglobin (Hb), platelets (PLT), and white blood cells (WBC) all significantly (p < 0.0001) correlated with the paired FUVB samples (R = 0.50, 0.49, and 0.84, respectively). Hb, PLT, and WBC values were clinically comparable but statistically higher in neonatal blood (the differences were 2.3 g/dL, 30,000 cells/MUL, and 2,800 cells/MUL, respectively; p < 0.007 for all comparisons). CONCLUSIONS: FUVB is suitable for obtaining CBC/diff. FUVB is an appropriate second source for BCX as it yields additional true pathogens. Our findings may support the presence of "culture-negative sepsis" in some neonates. PMID- 30300891 TI - Advances and Current Challenges Associated with the Use of Human Induced Pluripotent Stem Cells in Modeling Neurodegenerative Disease. AB - One of the most profound advances in the last decade of biomedical research has been the development of human induced pluripotent stem cell (hiPSC) models for identification of disease mechanisms and drug discovery. Human iPSC technology has the capacity to revolutionize healthcare and the realization of personalized medicine, but differentiated tissues derived from stem cells come with major criticisms compared to native tissue, including variability in genetic backgrounds, a lack of functional maturity, and differences in epigenetic profiles. It is widely believed that increasing complexity will lead to improved clinical relevance, so methods are being developed that go from a single cell type to various levels of 2-D coculturing and 3-D organoids. As this inevitable trend continues, it will be essential to thoroughly understand the strengths and weaknesses of more complex models and to develop criteria for assessing biological relevance. We believe the payoff of robust, high-throughput, clinically meaningful human stem cell models could be the elimination of often inadequate animal models. To facilitate this transition, we will look at the challenges and strategies of complex model development through the lens of neurodegeneration to encapsulate where the disease-in-a-dish field currently is and where it needs to go to improve. PMID- 30300892 TI - Determination of Cardiac Output: A Game of Thrones. PMID- 30300893 TI - ACTA2 Cerebral Arteriopathy: Not Just a Puff of Smoke. AB - BACKGROUND: Missense mutations in the gene that codes for smooth muscle actin, ACTA2, cause diffuse smooth muscle dysfunction and a distinct cerebral arteriopathy collectively known as multisystemic smooth muscle dysfunction syndrome (MSMDS). Until recently, ACTA2 cerebral arteriopathy was considered to be a variant of moyamoya disease. However, recent basic science and clinical data have demonstrated that the cerebral arteriopathy caused by mutant ACTA2 exhibits genetic loci, histopathology, neurological sequelae, and radiographic findings unique from moyamoya disease. We conducted a literature review to provide insight into the history, clinical significance, and neurosurgical management of this recently described novel cerebral arteriopathy. SUMMARY: We performed a literature search using PubMed with the key words "ACTA2 mutation," "ACTA2 cerebral arteriopathy," and "multisystemic smooth muscle dysfunction syndrome." Case reports with confirmed ACTA2 mutations and cerebral arteriopathy were included in our review. Our literature search revealed 15 articles (58 cases) of confirmed ACTA2 cerebral arteriopathy. Distinctive features of this arteriopathy included an aberrant internal carotid circulation with dilatation of the proximal segments, occlusive disease at the distal segments, and dolichoectasia. As such, mutant ACTA2 predisposed patients to ischemic strokes as children. Direct and indirect cerebral revascularization procedures are the mainstay treatment options with varying degrees of success. Key Messages: ACTA2 cerebral arteriopathy is a recently described novel cerebrovascular disease seen in patients with MSMDS. Patients currently diagnosed with moyamoya disease who also have dysfunction of smooth muscle organs may benefit from reevaluation by a medical geneticist and ACTA2 genotyping. PMID- 30300894 TI - Favorable Outcomes of Elderly ABO-Incompatible Kidney Transplantation-Pilot Single Center Experience. AB - BACKGROUND: The growth in the end-stage kidney disease (ESKD) population has been predominantly in the older adult population. In Japan, ABO-incompatible kidney transplantation has become an acceptable treatment option. However, few studies have been conducted on elderly ABO-incompatible kidney transplantation. PATIENTS AND METHODS: Seventeen patients aged 60 years and older who received their grafts from ABO-incompatible living donors at our institution between December 2006 and September 2016 were enrolled in this study, and the outcome of these recipients was evaluated. RESULTS: All 17 patients underwent successful kidney transplantation. Both overall patient and graft survival rates were 100, 100, and 83.3% at posttransplant 1, 3, and 5 years respectively. Six of the 17 patients (35.3%) had an episode of biopsy-proven acute cellular rejection. Two patients who developed steroid- and deoxyspergualin-resistant acute rejection required anti-human thymocyte immunoglobulin. CONCLUSION: ABO-incompatible kidney transplantation may be an effective radical renal replacement therapy for elderly patients with ESKD, although it could be a high-risk procedure. PMID- 30300895 TI - The Relationship between the Fetal Volume-Corrected Renal Artery Pulsatility Index and Amniotic Fluid Volume. AB - INTRODUCTION: To evaluate if the volume-corrected renal artery pulsatility index (vcRA-PI) is more closely related to the amniotic fluid level than the uncorrected or the gestational age (GA)-adjusted RA-PI. METHODS: RA-PI and kidney volume were measured in low- and high-risk pregnancies at 17-38 weeks. Fetal anomalies associated with nonrenal causes of abnormal amniotic fluid volume were excluded. The vcRA-PI was calculated by dividing the RA-PI by the renal volume. The RA-PI was adjusted for GA, to obtain the GA-adjusted RA-PI. The uncorrected, GA-adjusted, and the vcRA-PI were related to the amniotic fluid level using nonparametric tests and receiver operating characteristic (ROC) curve analyses. RESULTS: 146 examinations from 59 pregnancies were reviewed. Of these, 16 had oligo- and 15 had polyhydramnios. A higher vcRA-PI was associated with oligohydramnios (OR 2.54, 95% CI 1.67-3.86, p < 0.001), while the uncorrected RA PI and GA-adjusted RA-PI were not able to predict oligohydramnios. ROC curve analysis showed a high predictive accuracy of the vcRA-PI for oligohydramnios (AUC 0.84, 95% CI 0.72-0.94). On the other hand, the uncorrected RA-PI and GA adjusted RA-PI significantly predicted polyhydramnios (p = 0.04 and 0.02, respectively), while the vcRA-PI did not. CONCLUSION: The vcRA-PI is superior to the uncorrected and the GA-adjusted RA-PI in predicting oligohydramnios.

AB - Considering the possibility of a common genetic background of vertigo and epilepsy, we genotyped an affected group of individuals with vertigo and an unaffected group, by studying 26 single-nucleotide polymorphisms (SNPs) in 14 genes which were previously reported to be of particular importance for epilepsy. Significant differences were found between the patients and the control group (chi2 = 38.3, df = 3, p = 1.6 * 10-7) for the frequencies of haplotypes consist ing of 2 SNPs located in chromosome 11 (rs1939012 and rs1783901 within genes MMP8 and SCN3B, respectively). The haplotype rs1939012:C-rs1783901:A, consisting of the minor-frequency alleles was found to be associated with a higher risk of vertigo (OR = 5.0143, 95% CI = 1.6991-14.7980, p = 0.0035). In contrast, the haplotype rs1939012:T-rs1783901:A showed a significant association with a decreased risk of the disease (OR = 0.0597, 95% CI = 0.0136-0.2620, p = 0.0002). Our results suggest that the SNPs rs1939012 and rs1783901 may play a potential role of gene regulation and/or epistasis in a complex etiology of vertigo.

Background: the World Health Organization (WHO) and the American Joint Cancer Committee (AJCC) modified the grading of pancreatic neuroendocrine neoplasms from a three-tiers (WHO-AJCC 2010) to a four-tiers system by introducing the novel category of NET G3 (WHO-AJCC 2017). OBJECTIVES: This study aims at validating the WHO-AJCC 2017 and identifying the most effective grading system. METHOD: 2102 patients were enrolled; entry criteria were i) performed surgery; ii) at least two years of follow-up; iii) observation time up to 2015. Data from 34 variables were collected; grading was assessed and compared for efficacy by statistical means including Kaplan Meier method, Cox regression analysis, Harrell's C statistics and Royston's explained variation in univariable and multivariable analyses. RESULTS: At descriptive analysis, the two grading systems demonstrated statistically significant differences for the major category sex but not for age groups. At Cox regression analysis, both grading systems showed statistically significant differences between grades for OS and EFS, however no statistically significant difference was observed between the two G3 classes of WHO-AJCC 2017. At multivariable analysis for the two models fitted to compare efficacy, the two grading systems performed equally well with substantially similar optimal discrimination and well-explained variation for both OS and EFS. The WHO-AJCC 2017 grading system retained statistically significant difference between the two G3 classes for OS but not for EFS. CONCLUSIONS: the WHO-AJCC 2017 grading is at least equally performing as the WHO AJCC 2010 but allows the successful identification of the most aggressive PanNET subgroup. Grading is confirmed as probably the most powerful tool for patient survival prediction.

AB - BACKGROUND: Endovascular clot retrieval (ECR) improves outcomes for acute ischaemic stroke with large artery occlusion. However, the provision of ECR requires resource-intensive comprehensive stroke centres (CSC), which are impractical to establish in regional hospitals. An alternative is a "hub-and spoke" model, whereby ischaemic strokes are triaged at the regional primary centres and where eligible, transferred to a CSC. We aimed to compare the outcomes of patients directly admitted to a CSC with patients treated in the "hub and-spoke" model. We hypothesize that there are no significant differences in clinical outcomes between the 2 systems. METHODS: We included patients undergoing ECR at a CSC. Patients were categorised into 2 groups; the first group included patients directly admitted to the CSC and the second group included patients in the "hub-and-spoke" model. Good clinical outcome was defined as modified Rankin Scale 0-2 and the difference between the 2 groups was tested by logistic regression. RESULTS: Of 178 patients, 50 (28%) presented directly to CSC and 128 (72%) were transferred from a referring hospital. The median age was 70 (interquartile range 58-77) and 61% were male. Thrombolysis in ischaemic cerebral infarction 2b/3 recanalisation was achieved in 79% of patients. Of the direct group, 63% (95% CI 48-77%) achieved good clinical outcomes compared to 52% (95% CI 43-61%) in the "hub-and-spoke" group (p = 0.233). CONCLUSION: This state-wide service model demonstrates comparable clinical outcomes to that described in clinical trials. We found no significant difference in outcome between patients directly admitted to CSC and those with "hub-and-spoke" service delivery.

PMID- 30300901 TI - Id1/NR2B Receptor Pathway Regulates Rat Cochlear Sensory Epithelial Cell Survival after Radiation. AB - Survival of cochlear sensory epithelial cells may be regulated by inhibitor of differentiation-1 (Id1) and the N-methyl-D-aspartic acid (NMDA) receptor. However, it is unclear whether Id1 and the NMDA receptor are involved in the radiation-mediated survival of rat cochlear sensory epithelial cells. Here, we show that the percentage of apoptotic cells increased, the percentage of cells in the S phase decreased, Id1 mRNA and protein expression decreased and the NMDA receptor subtype 2B (NR2B) mRNA and protein level increased in OC1 cells after radiation. Cells infected with the Id1 gene exhibited higher Id1 mRNA and protein levels and lower NR2B mRNA and protein levels than the control cells. In contrast, after transfection of the Id1 siRNA into OC1 cells, Id1 mRNA and protein expression decreased and NR2B mRNA and protein expression increased relative to that of the control group. Additionally, treatment with ifenprodil for 24 h before radiation reduced apoptosis and increased the percentage of cells in the S phase. Our results suggest that Id1 and NR2B might regulate the survival of OC1 cells following radiation.

PMID- 30300903 TI - Endothelial Function in Patients with Severe and Moderate Haemophilia A and B. AB - The life expectancy of patients with haemophilia has increased and therefore the interest in age-related comorbidities has grown. The aim of this study was to determine whether haemophilia patients have a different endothelial function compared with the general population. A total of 26 patients with severe or moderate haemophilia A or B, 14 controls and 36 patients with coronary artery disease (CAD) were included in this study. Five markers of endothelial dysfunction (MOEDs) were determined. Moreover, the endothelial function was examined using the Itamar Endo-PAT, and the reactive hyperemia index (RHI) was calculated from the results. The MOEDs soluble intercellular adhesion molecule-1 (p = 0.0095) and interleukin-6 (p = 0.010) were significantly higher for patients with haemophilia compared with the control group. The presence of increased adhesion molecule levels and low-grade inflammation is suggestive of a decreased endothelial function. RHI is impaired in CAD patients (1.862), whereas haemophilia patients have an RHI of 1.958 in comparison with 2.112 in controls (p = 0.127). Therefore, laboratory and functional measurements imply a possible higher risk for CAD in haemophilia patients. PMID- 30300904 TI - Impact of Prosthesis-Patient Mismatch on Survival after Mitral Valve Replacement: A Meta-analysis. AB - BACKGROUND: Numerous studies have demonstrated a negative impact of prosthesis patient mismatch (PPM) on long-term clinical outcomes after aortic valve replacement. However, the impact of PPM after mitral valve replacement (MVR) on clinical outcomes is still controversial. This study was conducted to evaluate the impact of PPM on early and long-term survival after MVR. METHODS: A literature search of five databases was performed. The primary and secondary outcomes were all-cause mortality and early mortality, respectively. Subgroup analyses were performed according to the risk of bias, patients' age, proportion of female patients, and proportion of patients with mechanical MVR. RESULTS: Eleven nonrandomized studies including 8,072 patients were included in this meta analysis. The overall incidence of PPM was 58.0% (range: 10.4-85.9%). The odds ratio of early mortality in nine studies was not significantly different between the PPM and non-PPM patients (odds ratio: 1.35; 95% confidence interval [CI]: 0.98-1.86). A pooled analysis in 11 studies demonstrated that all-cause mortality after MVR was higher in the PPM than non-PPM patients (hazard ratio [HR]: 1.39; 95% CI: 1.09-1.77). This analysis revealed a moderate to high heterogeneity (I 2 = 69.4%). When pooled analyses were performed in two subgroups according to the proportion of patients with mechanical MVR, there were low heterogeneity in each group. No other subgroup analyses demonstrated a significant difference in the HR of all-cause mortality. Funnel plots and Egger's tests showed no visually and statistically significant publication bias. CONCLUSION: The present meta analysis indicates that PPM negatively affects long-term survival after MVR. PMID- 30300905 TI - Icariin Improves Functional Behavior in a Mouse Model of Traumatic Brain Injury and Promotes Synaptic Plasticity Markers. AB - Epimedii Herba (EH) has been used in traditional Asian medicine to treat hemiplegia following stroke. Icariin, its major active component, is used as a quality-control marker and for its various pharmacological effects. We hypothesized that icariin would show protective effects following traumatic brain injury (TBI). The TBI mouse model was induced using a controlled cortical impact method. Body weight, brain damage, motor function, and cognitive function were evaluated. Synaptogenesis markers were analyzed to investigate potential mechanisms of action. The animals were divided into six groups: sham, control, minocycline-treated group, and icariin-treated (3, 10, and 30 mg/kg, p. o.) groups. The icariin 30 mg/kg-treated group regained body weight at 7 and 8 d post TBI. Icariin 30 mg/kg- and 10 mg/kg-treated groups showed enhanced sensory-motor function at 8 d post TBI in rotarod and balance beam tests. Icariin-treated groups showed increased recognition index in the novel object recognition test at all doses and increased spontaneous alternation in the Y-maze test at 30 mg/kg. Icariin upregulated brain-derived neurotrophic factor, synaptophysin and postsynaptic density protein 95 expressions. However, no protective effects against brain damage or neuronal death were observed. The current results provide a basis for using icariin following TBI and suggest that it could be a candidate for the development of therapeutic agents for functional recovery after TBI.

PMID- 30300909 TI - Genetic Depletion of Thromboxane A2/Thromboxane-Prostanoid Receptor Signalling Prevents Microvascular Dysfunction in Ischaemia/Reperfusion Injury. AB - OBJECTIVE: Activation of thromboxane A2 synthase (TXAS)/thromboxane A2 (TXA2)/thromboxane prostanoid (TP) receptor leads to arterial constriction, platelet aggregation and vascular injury. We attempted to characterize the microvascular dysfunction in ischaemia/reperfusion injury using genetically modified TXAS-/-, TP-/- and TXAS-/-TP-/- mice. APPROACH AND RESULTS: The cardiac micro-circulation and electrocardiograms were evaluated from B6, TXAS-/-, TP-/- and TXAS-/-TP-/- mice in response to intravenous saline, endothelin-1, U46619 (a TXA2 agonist) and myocardial ischaemia/reperfusion injury. Cardiac function was investigated with myocardial permeability, the troponin I concentration and the infarct size. Myocardial TXAS, TP, endothelial nitric oxide (NO) synthase (eNOS), nicotinamide adenine dinucleotide phosphate oxidase 4 (NOx4), 4-hydroxynonenal, interleukin (IL)-1beta, cell apoptosis, coronary effluent thromboxane B2 (TXB2) and superoxide anions (O2 -) and NO concentrations were measured. Mice mesenteric reactivity in response to various drugs was assessed by wire myography. In vivo fluorescent platelet adhesiveness to the mesenteric arterial endothelium after FeCl3 stimulation was examined. In B6 mice, ischaemia/reperfusion significantly increased levels of ST-segment elevation, myocardial TXAS, TP, NOx4, IL-1beta, apoptosis, coronary endothelin-1, TXB2, O2 - release and the infarct size, with concomitant decreases in eNOS, NO concentrations and cardiac micro-circulation. These effects were remarkably depressed in TXAS-/-, TP-/- and TXAS-/-TP-/- mice. Aspirin treatment or depletion of the TXAS, TP or TXAS/TP gene significantly attenuated the exaggerated vascular reactivity by vasoconstrictors and vasodilators and efficiently reduced platelet adhesion to the mesenteric endothelium under FeCl3 stimulation. CONCLUSION: Inhibiting TXAS/TXA2/TP signalling confers microvascular protection against oxidative injury in both cardiac and mesenteric arteries. PMID- 30300910 TI - Monocytes of Different Subsets in Complexes with Platelets in Patients with Myocardial Infarction. AB - Acute myocardial infarction (AMI) is associated with activation of various cells, including platelets that form monocyte-platelet complexes (MPCs). Here, we analysed MPC in vivo and in vitro and investigated the abilities of different monocyte subclasses to form MPC, the characteristics of the cells involved in MPC formation and MPC changes in AMI. We identified MPC by co-staining for platelet antigen CD41a and monocyte antigens CD14 and CD16. Platelet activation was evaluated from expression of phosphatidylserine as revealed by annexin V. Our results confirm published data and provide new information regarding the patterns of MPC in AMI patients. We found that the patterns of platelet aggregation with monocytes were different in AMI patients and controls: (1) in AMI patients, MPC formed by intermediate monocytes carry more platelets whereas in healthy controls more platelets aggregated with classical monocytes; (2) the numbers of MPC in AMI patients, being already higher than in controls, were further increased if these patients suffered various in-hospital complications; (3) on the basis of the CD41a fluorescence of the antibody-stained MPC, some of the aggregates seem to consist of monocytes and platelet-derived extracellular vesicles (EVs); (4) aggregation of monocytes with platelet EV occurred in in vitro experiments; and (5) these experiments demonstrated that monocytes from AMI patients aggregate with both platelets and platelet EVs more efficiently than do monocytes from controls. MPC in AMI patients may play an important role in this pathology. PMID- 30300911 TI - IL-9 Promotes the Development of Deep Venous Thrombosis by Facilitating Platelet Function. AB - The development of deep venous thrombosis (DVT) is a sterile inflammatory process related to cytokines, such as interleukin (IL)-6 or IL-17. IL-9 is a cytokine involved in many inflammatory diseases, including cystic fibrosis, ulcerative colitis, psoriasis and psoriatic arthritis. However, it remains unknown whether IL-9 is related to DVT. In this study, we characterized the role and mechanism of IL-9 in DVT. Analysis of the data of patients with and without DVT revealed that stasis, venous surgery as well as elevated IL-9 and sP-selectin levels were related to the development of DVT. We also showed for the first time that IL-9 receptor was expressed in mouse platelets, and it dramatically promoted the aggregation rate and expression of P-selectin (CD62P) in the presence of adenosine diphosphate, but otherwise exhibited no effect on platelets. This study also revealed that Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signalling pathway, not phosphoinositide 3 kinase/AKT pathway, was involved in the process. We also showed in a mouse model of stasis that the thrombus size (weight and length) and CD62P expression in the thrombus were higher and lower in the IL-9 group and IL-9 antibody group, respectively, than in the control group. All these findings indicated that IL-9 facilitated platelet function through the JAK2/STAT3 pathway, thus promoting the development of DVT. PMID- 30300912 TI - Spontaneous Septic Arthritis of Canine Elbows: Twenty-One Cases. AB - OBJECTIVE: This study provides information on clinical features, diagnosis, treatment and associated risk factors of spontaneous septic elbow arthritis in the dog. METHODS: Medical records between March 2007 and June 2015 were searched for cases of spontaneous septic elbow arthritis with a diagnosis based on clinical signs, arthrocentesis, cytological and microbiological analysis of elbow joint synovial fluid, radiography and outcome following treatment. RESULTS: Twenty-one cases of septic arthritis were identified. Pre-existing osteoarthritis was present in 14/15 elbows for which diagnostic imaging was available. Although all cases had increased neutrophil count on synovial fluid cytology, culture was only positive in 12/21. Despite initial improvement in lameness scores (pre treatment 9/10 [range: 1-10] versus post-treatment 3/10 [range: 1-5]), 11/12 had residual long-term lameness. Recurrence of infection was noted in 3/12 elbows for which long-term (>8 weeks) follow-up was available. There was an acute mortality rate of 2/21 associated with severe systemic sepsis. CLINICAL SIGNIFICANCE: Septic arthritis, even in the absence of pyrexia, should be considered as a major differential diagnosis in middle aged, large breed dogs, with pre-existing elbow arthritis, that suffer an acute onset lameness, with elbow joint effusion and discomfort. Antibiotic therapy alone was effective for treatment with high initial response rates. Chronic lameness post-treatment was common, and a high rate of recurrence was seen with 3/12 dogs suffering more than one episode. PMID- 30300913 TI - Sensitivity and Specificity of a Weight Distribution Platform for the Detection of Objective Lameness and Orthopaedic Disease. AB - INTRODUCTION: Weight distribution and off-loading at the stance are commonly used subjective assessments during the orthopaedic examination. The clinical relevance, sensitivity and specificity of limb off-loading have not yet been established. The aim of the study was to assess off-loading on a weight distribution platform (WDP) and determine the sensitivity and specificity at various cut-off points for the detection of objective lameness (OL) and orthopaedic disease (OD). MATERIALS AND METHODS: The total pressure index was used to determine OL on a pressure-sensitive walkway (PSW). Normal weight distribution on both the PSW and WDP was considered 30/30/20/20. A total pressure index standard deviation of 2 was used. The sensitivity and specificity of the WDP for the identification of OL and OD was determined at cut-off points 1 to 6 below normal weight distribution values. RESULTS: All patients in the study (n = 50) had confirmed OD. The PSW identified 36/50 (74%) patients as OL; these were deemed to be OL for sensitivity and specificity analysis of WDP data. At cut-off point 1, the WDP had the highest sensitivity for OD (84%) and OL (97%). At cut off point 6, the WDP had the highest specificity for OD (98%) and OL (98%). The highest combination of sensitivity and specificity for both OD (1.65) and OL (1.80) was at cut-off point 2. DISCUSSION/CONCLUSION: The WDP provided the highest combined sensitivity and specificity at cut-off point 2 below the normal value for the detection of both OL and OD. PMID- 30300914 TI - Reproducibility, Accuracy and Effect of Autoclave Sterilization on a Thermoplastic Three-Dimensional Model Printed by a Desktop Fused Deposition Modelling Three-Dimensional Printer. AB - OBJECTIVES: The main purpose of this study was to determine the reproducibility and accuracy of a three-dimensional (3D) bone model printed on a desktop 3D printer based on fused deposition modelling (FDM) technology with polylactic acid (PLA) and the effect of autoclave sterilization on the printed models. METHODS: Computed tomographic images of the tibia were obtained from 10 feline cadavers, used to create a bone surface-rendering file and sent to the 3D printing software. Right and left tibias were each printed five times with the FDM desktop 3D printer using PLA plastic material. Plastic models and cadaveric bones were measured with a profile projector device at six predetermined landmarks. Plastic bones were then sterilized using an autoclave before being re-measured applying the same method. Analyses of printed model size reliability were conducted using intra-class correlation coefficients (ICC) and Bland-Altman plots. RESULTS: The ICC always showed an almost perfect agreement when comparing 3D-printed models issued from the same cadaveric bone. The ICC showed moderate agreement for one measurement and strong/perfect agreement for others when comparing a cadaveric bone with the corresponding 3D model. Concerning the comparison of the same 3D printed model, before and after sterilization, ICC showed either strong or perfect agreement. CLINICAL SIGNIFICANCE: Rapid-prototyping with our FDM desktop 3D-printer using PLA was an accurate, a reproducible and a sterilization compliant way to obtain 3D plastic models. PMID- 30300915 TI - Computed Tomographic Trochlear Depth Measurement in Normal Dogs. AB - OBJECTIVES: The main purpose of this study was to describe the relationship between patellar maximal craniocaudal thickness and femoral trochlear groove depth in normal dogs and to valuate the intra-observer or inter-observer variability of maximal trochlear depth and maximal patellar craniocaudal thickness using computed tomography. METHODS: Trochlear groove depth and patellar maximal craniocaudal thickness of 40 limbs (20 dogs) were measured by three independent veterinarians using three-dimensional multiplanar reconstruction computed tomography images. The patellar maximal craniocaudal thickness/trochlear depth ratio was determined. RESULTS: The mean ratio of these stifles was 0.46 (range 0.24-0.70), meaning that the mean maximal depth of the trochlea was 46% of the mean maximal-patellar thickness. CLINICAL SIGNIFICANCE: A wide range of maximal-patellar-craniocaudal-thickness/maximal trochlear-depth ratio was found suggesting that breed studies should be performed to determine a breed-specific patellar-thickness/trochlear-depth ratio. To make decisions on when and where to perform a sulcoplasty during patellar luxation surgery, patella/trochlea thickness relationship should be measured for each breed with patellar tracking from stifle hyperflexion to stifle hyperextension. PMID- 30300916 TI - Comparison of Early Measurements of the Distraction Index, Norberg Angle on Distracted View and the Official Radiographic Evaluation of the Hips of 215 Dogs from Two Guide Dog Training Schools. AB - OBJECTIVES: The main purpose of this article is to evaluate the correlation between the distraction index (DI) and Norberg angle values in distracted hips (distraction Norberg angle, DNA) at 4 months of age and the official hip score based on the Federation Cynologique Internationale (FCI) grid at 12 months of age. METHODS: For dogs (n = 215) from two guide dog training organizations, the DI and DNA were measured by a single expert on distraction radiographs performed at 4 months of age. The FCI score was determined by the same expert at 12 months of age on a standard hip-extended view.Statistical analysis included receiver operating characteristic curve analysis and concordance correlation coefficient calculation. RESULTS: The mean DI was 0.48, the mean DNA was 86.5 degrees and 59.5% of hips had an A FCI score. The concordance correlation coefficient of DI and DNA was 0.78. The DI threshold for D- and E-scored hips that was associated with the least misclassification was 0.58 (sensitivity [Se] = 0.6, specificity [Sp] = 0.82). The DNA threshold that was associated with the least misclassification was 85 degrees (Se = 0.83, Sp = 0.68). CLINICAL SIGNIFICANCE: DNA has a fair correlation with DI at 4 months and reflects hip passive laxity. D and E FCI scores at 12 months cannot be reliably predicted from the 4 months value of DI or DNA but 96% of hips with DI < 0.58 at 4 months had an A, B or C FCI score at 12 months of age. Similarly, 98% of hips with DNA > 85 degrees at 4 months had an A, B or C FCI score at 12 months of age. PMID- 30300917 TI - Wnt-induced activation of glucose metabolism mediates the in vivo neuroprotective roles of Wnt signaling in Alzheimer disease. AB - Dysregulated Wnt signaling is linked to major neurodegenerative diseases, including Alzheimer disease (AD). In mouse models of AD, activation of the canonical Wnt signaling pathway improves learning/memory, but the mechanism for this remains unclear. The decline in brain function in AD patients correlates with reduced glucose utilization by neurons. Here, we test whether improvements in glucose metabolism mediate the neuroprotective effects of Wnt in AD mouse model. APPswe/PS1dE9 transgenic mice were used to model AD, Andrographolide or Lithium was used to activate Wnt signaling, and cytochalasin B was used to block glucose uptake. Cognitive function was assessed by novel object recognition and memory flexibility tests. Glucose uptake and the glycolytic rate were determined using radiotracer glucose. The activities of key enzymes of glycolysis such as hexokinase and phosphofructokinase, Adenosine triphosphate (ATP)/Adenosine diphosphate (ADP) levels and the pentose phosphate pathway and activity of glucose-6 phosphate dehydrogenase were measured. Wnt activators significantly improved brain glucose utilization and cognitive performance in transgenic mice. Wnt signaling enhanced glucose metabolism by increasing the expression and/or activity of hexokinase, phosphofructokinase and AMP-activated protein kinase. Inhibiting glucose uptake partially abolished the beneficial effects of Wnt signaling on learning/memory. Wnt activation also enhanced glucose metabolism in cortical and hippocampal neurons, as well as brain slices derived from APPswe/PS1E9 transgenic mice. Combined, these data provide evidence that the neuroprotective effects of Wnt signaling in AD mouse models result, at least in part, from Wnt-mediated improvements in neuronal glucose metabolism.

PMID- 30300919 TI - An application of data mining to identify potential risk factors for anophthalmia and microphthalmia. AB - BACKGROUND: We examined a large number of variables to generate new hypotheses regarding a wider range of risk factors for anophthalmia/microphthalmia using data mining. METHODS: Data were from the National Birth Defects Prevention Study, a multicentre, case-control study from 10 centres in the United States. There were 134 cases of "isolated" and 87 "nonisolated" (with other major birth defects) of anophthalmia/microphthalmia and 11 052 nonmalformed controls with delivery dates October 1997-December 2011. Using random forest, a data mining procedure, we compared the two case types with controls for 201 variables. Variables considered important ranked by random forest were included in a multivariable logistic regression model to estimate odds ratios and 95% confidence intervals. RESULTS: Predictors for isolated cases included paternal race/ethnicity, maternal intake of certain nutrients and foods, and childhood health problems in relatives. Using regression, inverse associations were observed with greater maternal education and with increasing intake of folate and potatoes. Odds were slightly higher with greater paternal education, for increased intake of carbohydrates and beans, and if relatives had a childhood health problem. For nonisolated cases, predictors included paternal race/ethnicity, maternal intake of certain nutrients, and smoking in the home the month before conception. Odds were higher for Hispanic fathers and smoking in the home and NSAID use the month before conception. CONCLUSIONS: Results appear to support previously hypothesised risk factors, socio-economic status, NSAID use, and inadequate folate intake, and potentially provide new areas such as passive smoking pre-pregnancy, and paternal education and ethnicity, to explore for further understanding of anophthalmia/microphthalmia. PMID- 30300920 TI - Development and Validation of a Fall Prevention Knowledge Test. AB - Falls are a serious, persistent problem in hospitals. Ensuring that all hospital staff have adequate knowledge of how to prevent falls is the first step in prevention. We identified validated fall prevention knowledge tests (FPKTs) and planned to conduct a systematic literature review. When the review identified a lack of FPKTs, we developed and evaluated a FPKT, confirmed its conceptual framework, identified the content domain, drafted test items, devised the format, selected items for empirical examination, and conducted a psychometric evaluation. We randomly divided a 209-subject data set into test and validation samples to make item reduction decisions and examine reliability and validity. The typical respondent was a white, 42-year old female nurse with a bachelor's degree and 7 years' experience. Subjects were confident in their ability to prevent falls, rating themselves an 8 on a self-efficacy scale of 1 (not at all) to 10 (very). The 11-item FPKT scale (range 0-11) attained a tetrachoric coefficient of 0.73, confirming initial reliability. FPKT mean scores obtained before and after fall prevention education improved from 5.1 +/- 1.8 to 6.6 +/- 1.7. Statistically significant differences (paired t-test = 12.4, p < .001) confirmed validity. A robust way to assess nurses' knowledge of fall prevention is needed to inform effective educational programs. Addressing gaps in validated FPKTs provides an opportunity to inform and evaluate effective fall prevention programs.

The pharmacogenetic (PG) effect of variants at the loci of organic cation transporter 1 (OCT1) and UDP-glucuronosyltransferase 2B7 (UGT2B7) on age dependent morphine clearance were evaluated in a cohort of critically ill neonatal patients using an opportunistic sampling design. Our primary results demonstrate the significant influence of OCT1 genotype (P < 0.05) and gestational age (P <= 0.005) on morphine PKs. A physiologically based pharmacokinetic (PBPK) model for morphine that accounted for OCT1 ontogeny and PG effect in post-term neonates adequately described the clinically observed variability in morphine PKs. This study serves as a proof of concept for genotype-dependent drug transporter ontogeny in neonates. PMID- 30300923 TI - Pressure-Induced Stable Binary Compounds of Magnesium and Germanium. AB - Motivated by the possibility to obtain unusual stoichiometric compounds (e.g., Na Cl and Mg-O systems) with exotic properties at high pressures, we systematically investigated the high-pressure structures and chemical bonding of Mg-Ge systems by using a structure-searching method and first-principles calculations. Compared with the stable composition of Mg2 Ge at ambient pressure, several stoichiometries (e.g., Mg3 Ge, MgGe, and MgGe2 ) were predicted to be stable under high pressures. The Pm 3? m Mg3 Ge structure consists of a 12-fold coordinated face-sharing GeMg12 cuboctahedron, whereas the P4/mmm MgGe and Cmcm MgGe2 phases form MgGe8 hexahedrons and MgGe4 polygons, respectively. All the stable phases of Mg-Ge compounds under high pressures exhibit metallic features owing to overlap between the conduction and valence bands. For Cmcm MgGe2 , the projected density of states near the Fermi energy mainly derive from Ge s, Ge p, and Ge d, which are responsible for its metallicity. The calculated superconducting critical temperature values of Cmcm Mg2 Ge and P4/mmm MgGe reach 10.3 and 9.07 K at 5 GPa, respectively. PMID- 30300924 TI - Addition of the C-terminus of CD6 to a chimeric antigen receptor enhances cytotoxicity and does not compromise expression. AB - T cells expressing chimeric antigen receptors (CARs) are a promising new cancer immunotherapy that has now reached the clinic. CARs are synthetic receptors that redirect T cells towards a tumour-associated antigen and activate them through various fused signalling regions, for example derived from CD3zeta, 4-1BB or CD28. Analysis of the optimal combination of CAR components including signalling domains is not yet comprehensive and may vary with the particular application. The C-terminus of the T-cell surface receptor CD6 is critical for its co stimulatory effects and signals through two phospho-tyrosine motifs that bind to the intracellular adaptor proteins GADS and SLP-76. Addition of the C terminus of CD6 did not compromise CAR expression, showing it was a stable moiety that can be used independently of the native receptor. A third-generation CAR containing 4 1BB, CD3zeta and the C terminus of CD6 (4-1BBz-CD6) enhanced interferon-gamma release and cytotoxicity when compared with the second-generation 4-1BB CD3zeta (4-1BBz) CAR. The CD6 C terminus is a valuable addition to potential components for modular design of CARs to improve effector function, particularly cytotoxicity. PMID- 30300925 TI - Connexin and pannexin (hemi)channels: emerging targets in the treatment of liver disease. AB - Connexin proteins are the building blocks of hemichannels, which dock further between adjacent cells to form gap junctions. Gap junctions control the intercellular exchange of critical homeostasis regulators. By doing so, gap junctions control virtually all aspects of the hepatic life cycle. In the last decade, it has become clear that connexin hemichannels also provide a pathway for cellular communication on their own independent of their role as structural precursors of gap junctions, namely between the cytosol of an individual cell and its extracellular environment. In contrast to gap junctions, connexin hemichannels become particularly active in liver disease by facilitating inflammation and cell death. This equally holds true for cellular channels composed of pannexins, being connexin-like proteins recently identified in the liver that gather in structures reminiscent of hemichannels. This paper gives an overview of the involvement of connexin-based and pannexin-based channels in non cancerous liver disease. This article is protected by copyright. All rights reserved. PMID- 30300926 TI - Parents' Perceptions and Use of School-Based Body Mass Index Report Cards. AB - BACKGROUND: Obesity in children and adolescents has become one of the most critical public health problems in the United States. Schools may play an important role in raising awareness and possibly slowing the obesity epidemic. METHODS: The purpose of this study was to gather information on parents' perception and use of body mass index (BMI) report cards provided by public schools through the administration of a questionnaire. The questionnaire was developed with the assistance of physical educators, pediatricians, and exercise scientists. The questionnaires were backpacked home with 1127 students in 6 Arkansas public schools. Parents completed and returned 404 questionnaires. RESULTS: Findings indicate that parents are supportive of schools reporting BMI and providing information on healthier lifestyles. However, most parents reported not making any adjustment to their child's diet and physical activity habits based on the BMI reports. Approximately half of parents (55%) thought the BMI report accurately reflected their child's health status. Approximately half of the parents reported their child's BMI report led them to think about their family's health habits. CONCLUSIONS: Although parents do support receiving BMI information from schools, many did not indicate using the data to initiate changes such as increased physical activity or healthy eating. PMID- 30300927 TI - Correlates of Patient-Centered Medical Home Recognition in School-Based Health Centers. AB - BACKGROUND: The patient-centered medical home (PCMH) is promoted as a way to improve access to care, health care outcomes, and control costs. The organizational, environmental, and patient characteristics associated with school based health centers (SBHCs) obtaining PCMH recognition is currently unknown. A multitheoretical approach was used to explore the correlates of formal PCMH recognition in SBHCs. METHODS: The 2013-2014 National Census of School-Based Health Centers was used as the primary data source for this analysis. Multivariable logistic regression was used to assess the odds of an SBHC obtaining any type of PCMH recognition, and obtaining national PCMH recognition. RESULTS: Only 29% of SBHCs had received any type of recognition as a PCMH and 17% reported receiving national-level recognition. School-based health centers that were managed care preferred providers, received Health Resources and Services Administration SBHC Capital Funding, and based in schools without adolescents had greater odds of both types of PCMH recognition outcomes. High levels of revenue from patient billing and more staff were also associated with national PCMH recognition. CONCLUSIONS: Financial and personnel resources are needed for national-level PCMH recognition, and managed care is supportive of PCMH implementation. Efforts should be made to increase medical home activity in SBHCs that serve adolescents. PMID- 30300928 TI - Well-Being and Academic Achievement: Differences Between Schools From 2002 to 2010 in the Helsinki Metropolitan Area. AB - BACKGROUND: We studied school-level differences in academic achievement and well being from 2002 to 2010 in the Helsinki Metropolitan Area, as well as the connection between academic achievement, well-being, and socioeconomic composition. METHODS: The School Health Promotion Study covered 109 schools and 78% of schoolchildren (N = 100,413; aged 14 to 16 years). Depression was measured with the modified Beck Depression Scale and academic achievement with the grade point average. Trajectory analysis identified groups of schools that were as heterogeneous over time as possible. RESULTS: Six school trajectories differing in academic achievement and 3 in well-being were observed. Differences between the trajectories persisted over time. Academic achievement and well-being were related: schools on a poor achievement trajectory were more often on a low-well being trajectory. The poor socioeconomic composition of students was more common in low-academic achievement and well-being trajectories. CONCLUSIONS: Academic achievement and well-being differed between schools and are closely related to each other and to the school's socioeconomic composition. Differences between the schools did not increase over time. Educational policies aimed at reducing differences should address both academic achievement and well-being. PMID- 30300929 TI - Disparities in Health Risk Behaviors and Health Conditions Among Rhode Island Sexual Minority and Unsure High School Students. AB - BACKGROUND: Sexual minority students have higher risk for health-related behaviors. We examined 5 domains including 34 health risk behaviors and health conditions among sexual minorities and unsure students in Rhode Island. We also included sexual contact of heterosexually identified students to capture heterosexually identified students who may be considered sexual minorities by their behavior. METHODS: We used the 2007-2015 Rhode Island Youth Risk Behavior Survey data (N = 14,264). We categorized students into 4 groups: students self identified as heterosexual and reported no sexual contact with same sex only or both sexes (group 1); self-identified as heterosexual and reported sexual contact with same sex only or both sexes (group 2); self-identified as lesbian, gay, bisexual (group 3); and responded as unsure (group 4). We used multivariable adjusted logistic regression analyses to evaluate associations of sexual minority and unsure students with 34 health risk behaviors and health conditions accounting for complex sampling design. RESULTS: Students in groups 2-4 were more likely to engage in health-risk behaviors including violent behaviors, attempted suicide, substance use, and no physical activity than their peers. CONCLUSIONS: As sexual minority youth continue to report higher rates of health-related risk behaviors, targeted evidence-based prevention approaches must focus on reducing these risk behaviors among those youth. PMID- 30300930 TI - No Association Between Active Commuting to School, Adiposity, Fitness, and Cognition in Spanish Children: The MOVI-KIDS Study. AB - BACKGROUND: Walking and bicycling (active commuting) to school may be a useful strategy to increase the daily amount of physical activity, and, potentially, improve children's health. However, it is unclear whether active commuting to school (ACS) has the potential to improve physical health and cognitive performance in children. Our aim was to examine the relationship between ACS with adiposity indicators, physical fitness, and cognitive performance in 4- to 7-year old children. METHODS: We conducted a cross-sectional study with 1159 children from the provinces of Cuenca and Ciudad Real, Spain. ACS was self-reported by parents. Adiposity (body mass index, waist circumference, body fat mass, and triceps skinfold thickness) and physical fitness (cardiorespiratory and muscular fitness) were measured by standard procedures. Cognitive performance was assessed using the Battery of General and Differential Aptitudes. Data analysis included analysis of covariance. RESULTS: We found no differences in adiposity, physical fitness, and cognitive performance between active commuters and nonactive commuters. CONCLUSIONS: Walking to school had no positive impact on adiposity, physical fitness, and cognition in 4- to 7-year-old children. Future studies should examine the intensity and duration of walking to school needed to provide benefits in health and cognitive performance. PMID- 30300931 TI - Schoolteachers' and Administrators' Perceptions of Concussion Management and Implementation of Return-to-Learn Guideline. AB - BACKGROUND: Concussions are a public health concern and concussion management in school requires a team approach. We examined schoolteachers' and administrators' perceptions of concussions, management, and implementation of return-to-learn (RTL) guidelines. METHODS: We audio-recorded and transcribed semistructured interviews with teachers (N = 16) and administrators (N = 6) from a public school system. We analyzed data using an analytic induction and constant comparison approach. RESULTS: Two themes emerged: different understanding, and school context. Participants with no sport coaching experience were less familiar with concussions than those who coached a sport. Participants with personal experience with concussions were more sympathetic toward concussed students' needs. Teachers expressed feeling ill-equipped to implement RTL guidelines without specific instructions in the complex school environment. However, school administrators had minimal understanding of teacher-described challenges. CONCLUSIONS: Teachers and administrators recognize that concussions are a health concern, but differ in their perceptions of concussions, management, and implementation of RTL guidelines. Personal experiences mediate individual perceptions about concussions. The daily realities of a school environment complicate teachers' capacity to implement RTL guidelines. Conversely, school administrators did not express awareness of any challenges with concussion management. To best facilitate students' recovery schools should include all stakeholders when devising concussion management policies. PMID- 30300932 TI - Systematic Review: Frameworks Used in School-Based Interventions, the Impact on Hispanic Children's Obesity-Related Outcomes. AB - BACKGROUND: Childhood obesity among Hispanic children is a public health concern in the United States and Mexico. Although experiences from school-based intervention programs aimed at influencing obesity-related behaviors have been positive, the understanding of those framework elements that are associated with successful outcomes is limited. The purpose of this study was to examine the frameworks used within school-based intervention programs in the United States and Mexico that showed improvements in obesity-related outcomes among Hispanic children. METHODS: A systematic review of the literature was conducted using 4 electronic databases. Inclusion criteria included: incorporating a framework or aspects of frameworks within an intervention, more than 50% of Hispanic children used in the study and obesity-related outcomes (eg, dietary behaviors and anthropometric measurements). Data extraction and evaluation were completed using the Academy of Nutrition and Dietetics Evidence Analysis Manual. RESULTS: Ten articles (United States = 4; Mexico = 6) meeting inclusion criteria were evaluated. Eight studies that included a community-based framework, intensive nutrition education, and continuous communication among stakeholders resulted in improvements in dietary behaviors and anthropometric measurements among children compared to control groups. CONCLUSIONS: Incorporating community-based frameworks may increase the efficacy of school-based intervention programs to reduce obesity related outcomes among Hispanic children. PMID- 30300933 TI - Bullying Victimization in Schools: Why the Whole School, Whole Community, Whole Child Model Is Essential. AB - BACKGROUND: Bullying is more likely to happen in schools than in any other location. The purpose of this study is to use decision tree analyses to predict specific risk factors for bullying to identify areas of interest for school-based bullying prevention. METHODS: We obtained data from the 2013 National Crime Victimization Study (NCVS) School Crime Supplement. We used case-wise deletion to create a sample with completed data based on the measure of bullying (N = 4967). The dependent variable for this study was bullying. We used chi-square automatic interaction detection (CHAID) to uncover predictors of bullying victimization in schools. RESULTS: Results suggest that 21.7% of the participants were bullied during the 6 months prior to the survey. Being distracted in class and being involved in a fight were the top statistically significant variables for bullying victimization in schools. Fear of being attacked and seeing hate-related words or symbols in school were also strong predictors of bullying. CONCLUSIONS: Bullying victimization can often be predicted. Therefore, school personnel can implement programs and policies consistent with the Whole School, Whole Community, Whole Child (WSCC) model to improve the social and emotional climate in schools and proactively reduce opportunities for bullying victimization. PMID- 30300934 TI - Evaluation of the Process of Implementing an Outdoor School Ground Smoking Ban at Secondary Schools. AB - BACKGROUND: Although outdoor smoking bans at school are becoming important, it remains unclear whether successful implementation is feasible and what conditions promote it. Therefore, this study evaluates the implementation process by identifying important factors. METHODS: Interviews were held with directors of 24 secondary schools that had decided to implement an outdoor school ground smoking ban, to identify important factors during implementation. Additionally, observations were made before and (about 4 weeks) after implementation to evaluate adherence to guidelines. Data were analyzed using a thematic approach. RESULTS: During implementation, the following items were important: smoking ban (eg, guidelines), school (eg, policy, enforcement, environmental factors, resources, etc), and external factors (eg, social environment). Four schools were unable to implement the ban, 20 schools implemented the ban but student adherence was low, and at 4 schools, staff members still smoked on school grounds. CONCLUSIONS: Although implementation is feasible, there are challenges. Schools need to apply a phased/dynamic process with ample lead time and clear communication of the policy. Directors should deal with offenders by strictly enforcing the ban and helping them stop smoking. This study offers information to help institutes implement an outdoor smoking ban to further protect adolescents from the harm of smoking. PMID- 30300935 TI - Community phylogeny of the globally critically imperiled pine rockland ecosystem. AB - PREMISE OF THE STUDY: Community phylogenetic methods incorporate information on evolutionary relationships into studies of organismal assemblages. We used a community phylogenetic framework to investigate relationships and biogeographic affinities and to calculate phylogenetic signal of endemism and invasiveness for the flora of the pine rocklands-a globally critically imperiled ecosystem with a significant portion of its distribution in South Florida, United States. METHODS: We reconstructed phylogenetic relationships of 538 vascular plant taxa, which represent 92.28% of the vascular flora of the pine rocklands. We estimated phylogenetic signal for endemism and invasiveness using phylogenetic generalized linear mixed models. We determined the native range for each species in the data set and calculated the total number of species sourced from each region and all possible combinations of these regions. KEY RESULTS: The pine rockland flora includes representatives of all major vascular plant lineages, and most species have native ranges in the New World. There was strong phylogenetic signal for endemism, but not for invasiveness. CONCLUSIONS: Community phylogenetics has high potential value for conservation planning, particularly for fragmented and endangered ecosystems like the pine rockland. Strong phylogenetic signal for endemic species in our data set, which also tend to be threatened or endangered, can help to identify species at risk, as well as fragments where those species occur, highlighting conservation priorities. Our results indicate, at least in the pine rockland ecosystem, no phylogenetic signal for invasive species, and thus other information must be used to predict the potential for invasiveness. PMID- 30300936 TI - Interprofessional Intervention to Improve Geriatric Consultation Timing on an Acute Medical Service. AB - OBJECTIVES: To determine whether an interprofessional intervention would improve the use and timing of a geriatric consultation on a hospitalist service. DESIGN: Difference-in-differences (DID), which measures the difference in improvement over time between intervention and control team patients attributable to the intervention. SETTING: 1,000-bed U.S. academic medical center. PARTICIPANTS: Individuals aged 60 and older admitted to a general medicine hospitalist service (N=7,038; n = 718 on intervention teams, n = 686 historical controls, n = 5,634 on control teams (concurrent and historic). INTERVENTION: On 2 of 11 hospitalist teams, a geriatrician attended multidisciplinary discharge rounds twice weekly and advised on the benefits of a geriatric consultation for individuals aged 60 and older. MEASUREMENTS: Primary outcome was percentage of hospitalizations resulting in a geriatric consultation. Secondary outcome was days to geriatric consultation. Both outcomes were controlled for age, sex, comorbidity, mean daily intensity of inpatient care utilization, and admission in the prior 30 days. In the primary analysis, length of stay was controlled. RESULTS: Intervention participants were more likely to have a geriatric consultation (DID = 2.35% absolute percentage points, 95% confidence interval (CI) = 0.59-4.39%) and to have a consultation sooner (DID = 3.61 fewer days, 95% CI = -1 to -7). CONCLUSION: An interprofessional intervention that focused on hospitalist ordering practices increased use of appropriate geriatric consultation and decreased time to consultation. This model of interprofessional effort is effective. Future adaptations are needed to target scarce geriatric resources without increasing overall use. PMID- 30300937 TI - Ticket to spawn: Combining economic and genetic data to evaluate the effect of climate and demographic structure on spawning distribution in Atlantic cod. AB - Climate warming and harvesting affect the dynamics of species across the globe through a multitude of mechanisms, including distribution changes. In fish, migrations to and distribution on spawning grounds are likely influenced by both climate warming and harvesting. The Northeast Arctic (NEA) cod (Gadus morhua) performs seasonal migrations from its feeding grounds in the Barents Sea to spawning grounds along the Norwegian coast. The distribution of cod between the spawning grounds has historically changed at decadal scales, mainly due to variable use of the northern and southern margins of the spawning area. Based on historical landing records, two major hypotheses have been put forward to explain these changes: climate and harvesting. Climate could affect the distribution through, for example, spatial habitat shifts. Harvesting could affect the distribution through impacting the demographic structure. If demographic structure is important, theory predicts increasing spawner size with migration distance. Here, we evaluate these hypotheses with modern data from a period (2000 2016) of increasing temperature and recovering stock structure. We first analyze economic data from the Norwegian fisheries to investigate geographical differences in size of spawning fish among spawning grounds, as well as interannual differences in mean latitude of spawning in relation to changes in temperature and demographic parameters. Second, we analyze genetically determined fish sampled at the spawning grounds to unambiguously separate between migratory NEA cod and potentially smaller sized coastal cod of local origin. Our results indicate smaller spawners farther away from the feeding grounds, hence not supporting the hypothesis that harvesting is a main driver for the contemporary spawning ground distribution. We find a positive correlation between annual mean spawning latitude and temperature. In conclusion, based on contemporary data, there is more support for climate compared to harvesting in shaping spawning ground distribution in this major fish stock in the North Atlantic Ocean. PMID- 30300938 TI - Weighing of Evidence by Health Technology Assessment Bodies: Retrospective Study of Reimbursement Recommendations for Conditionally Approved Drugs. AB - This study assessed whether five Health Technology Assessment (HTA) bodies in Europe were more negative about drugs with a Conditional Marketing Authorization (CMA) that are approved without controlled studies compared to CMA drugs that are approved based on controlled studies. The HTA recommendations were categorized into positive, restricted, and negative. A total of 92 HTA recommendations were available for 27 drugs. Thirty of 62 (48%) and 17 of 30 (57%) of the recommendations were negative for drugs with and without controlled studies, respectively. Overall, only 12 (13%) recommendations were positive. In all jurisdictions, recommendations between drugs with and drugs without controlled data were comparable, which suggests that the presence of controlled data is not decisive in HTA evaluations. The small proportion of unrestricted positive recommendations highlights difficulties with recommending the drugs in this cohort, which may be caused by scientific uncertainty or other factors. Earlier collaboration between stakeholders is advised in order to improve patient access. PMID- 30300939 TI - In Situ/Operando X-ray Spectroscopies for Advanced Investigation of Energy Materials. AB - Issues related to energy and the environment have now become of central and crucial importance in our societies. Low-carbon green energy will have a critical role in a necessary third industrial revolution. To reduce global greenhouse gas emissions in response to globalization and increasingly stringent carbon emission policies, large scale green energy production technologies must be established worldwide. A new age of human demand for green energy is thus coming and scientists are focused on finding new functional efficient and low-cost materials to generate clean and sustainable energy. Improving the energy conversion, generation, and storage efficiency of energy materials has always been a daunting challenge. For many important energy material systems, such as nanostructured catalysts, artificial photosynthetic systems, smart energy saving materials, and energy storage devices, monitoring the atomic and electronic structures close to the interfacial region in a real working environment is of paramount importance. Designing a better-performing material without comprehending its fundamental properties such as chemical states, atomic and electronic structures and how they are altered close to the interfacial regions during the physical and chemical reactions involved in their applications is very challenging. Understanding, controlling and tuning the interfaces in energy conversion and storage materials requires in situ/operando characterization tools, of which synchrotron X-ray spectroscopies, which have several unique features, are very suitable ones. X-ray absorption spectroscopy can be used to elucidate the local unoccupied electronic structure in the conduction band, and X-ray emission spectroscopy can be used to characterize the occupied electronic structure in the valence band. The derived resonant inelastic X-ray scattering reveals inter- and/or intra-electric transitions (i.e. d-d, f-f excitation and charge-transfer excitation) that reflect intrinsic chemical and physical properties. Scanning transmission X-ray microscopy is a chemical mapping technique with elemental sensitivity and spatial selectivity, which can therefore yield information about chemical composition in various spatial regions. This unique characteristic makes the method effective for investigating interfacial phenomena (such as electron transport, interface formation/deformation, defects, doping etc.). In situ/operando approaches have made the probing and understanding of changes in the atomic and electronic structures of energy materials in an operational environment feasible. This article presents a perspective of the pioneering developments as well as the recent achievements in in situ/operando synchrotron X-ray spectroscopies for the advanced investigation of energy materials. Four major energy material systems are identified: energy storage, energy generation, energy conversion, and energy saving material systems. Selected representative investigations of each systems are showcased and discussed demonstrating that in situ/operando synchrotron X-ray spectroscopy is truly essential for unraveling better fundamental knowledge for mechanism understanding and efficiency optimization of existing and emerging energy material systems. PMID- 30300940 TI - 5-Oxyacetic Acid Modification Destabilizes Double Helical Stem Structures and Favors Anionic Watson-Crick like cmo5 U-G Base Pairs. AB - Watson-Crick like G-U mismatches with tautomeric Genol or Uenol bases can evade fidelity checkpoints and thereby contribute to translational errors. The 5 oxyacetic acid uridine (cmo5 U) modification is a base modification at the wobble position on tRNAs and is presumed to expand the decoding capability of tRNA at this position by forming Watson-Crick like cmo5 Uenol -G mismatches. A detailed investigation on the influence of the cmo5 U modification on structural and dynamic features of RNA was carried out by using solution NMR spectroscopy and UV melting curve analysis. The introduction of a stable isotope labeled variant of the cmo5 U modifier allowed the application of relaxation dispersion NMR to probe the potentially formed Watson-Crick like cmo5 Uenol -G base pair. Surprisingly, we find that at neutral pH, the modification promotes transient formation of anionic Watson-Crick like cmo5 U- -G, and not enolic base pairs. Our results suggest that recoding is mediated by an anionic Watson-Crick like species, as well as bring an interesting aspect of naturally occurring RNA modifications into focus-the fine tuning of nucleobase properties leading to modulation of the RNA structural landscape by adoption of alternative base pairing patterns. PMID- 30300941 TI - "We Take Care of Patients, but We Don't Advocate for Them": Advance Care Planning in Prison or Jail. AB - OBJECTIVES: To investigate correctional healthcare providers' knowledge of and experience with advance care planning (ACP), their perspectives on barriers to ACP in correctional settings, and how to overcome those barriers. DESIGN: Qualitative. SETTING: Four prisons in 2 states and 1 large city jail in a third state. PARTICIPANTS: Correctional healthcare providers (e.g., physicians, nurses, social workers; N=24). RESULTS: Participants demonstrated low baseline ACP knowledge; 85% reported familiarity with ACP, but only 42% provided accurate definitions. Fundamental misconceptions included the belief that providers provided ACP without soliciting inmate input. Multiple ACP barriers were identified, many of which are unique to prison and jail facilities, including provider uncertainty about the legal validity of ACP documents in prison or jail, inmate mistrust of the correctional healthcare system, inmates' isolation from family and friends, and institutional policies that restrict use of ACP. Clinicians' suggestions for overcoming those barriers included ACP training for clinicians, creating psychosocial support opportunities for inmates, revising policies that limit ACP, and systematically integrating ACP into healthcare practice. CONCLUSION: Despite an increasing number of older and seriously ill individuals in prisons and jails, many correctional healthcare providers lack knowledge about ACP. In addition to ACP barriers found in the community, there are unique barriers to ACP in prisons and jails. Future research and policy innovation are needed to develop clinical training programs and identify ACP implementation strategies for use in correctional settings. PMID- 30300942 TI - Light-Induced Gold-Catalyzed Hiyama Arylation: A Coupling Access to Biarylboronates. AB - Organoboron compounds are versatile synthetic building blocks. We herein report a new strategy, a photochemical gold-catalyzed chemo-selective Hiyama arylation of B,Si bifunctionalized reagents with diazonium salts, which is orthogonal to common strategies and therefore a unique tool for synthesis of valuable biarylboronates. With this new methodology a wide array of diversely functionalized sp2 - and sp3 -hybridized biarylboronates were obtained. Notably, the synergism of gold catalysis with copper catalysis or palladium catalysis, allows for one-pot iterative C-X (heteroatom) and C-C couplings for the rapid assembly of several simple fragments to relatively complex molecules. Mechanistic studies indicated that photosensitizer-free conditions were superior to gold/Ru(bpy)3 Cl2 dual catalysis. PMID- 30300943 TI - FERONIA mutation induces high levels of chloroplast-localized Arabidopsides which are involved in root growth. AB - The FERONIA (FER) signaling pathway is known to have diverse roles in Arabidopsis thaliana, such as growth, reproduction, and defense, but how this receptor kinase is involved in various biological processes is not well established. In this work, we applied multiple mass spectrometry techniques to identify metabolites involved in the FER signaling pathway and to understand their biological roles. A direct infusion Fourier transform ion cyclotron resonance (FT-ICR)-MS approach was used for initial screening of wild-type and feronia (fer) mutant plant extracts, and Arabidopsides were found to be significantly enriched in the mutant. As Arabidopsides are known to be induced by wounding, further experiments on wounded and non-wounded leaf samples were carried out to investigate these oxylipins as well as related phytohormones using a quadrupole-time-of-flight (Q TOF) MS by direct injection and LC-MS/MS. In a root growth bioassay with Arabidopside A isolated from fer mutants, the wild-type showed significant root growth inhibition compared with the fer mutant. Our results therefore implicated Arabidopsides, and Arabidopside A specifically, in FER functions and/or signaling. Finally, matrix-assisted laser desorption/ionization MS imaging (MALDI MSI) was used to visualize the localization of Arabidopsides, and we confirmed that Arabidopsides are highly abundant at wounding sites in both wild-type and fer mutant leaves. More significantly, five micron high-spatial resolution MALDI MSI revealed that Arabidopsides are localized to the chloroplasts where many stress signaling molecules are made. PMID- 30300944 TI - Maternal paracetamol intake and fetal ductus arteriosus constriction or closure: a case series analysis. AB - Recent case reports describe an association between maternal paracetamol intake and fetal ductus arteriosus constriction or closure. To put these cases into perspective and explore causality, a structured literature search was conducted. The World Health Organization Uppsala Monitoring Centre (WHO-UMC) causality tool was applied to the cases retrieved. The search resulted in 12 papers with 25 case descriptions, of which one case was classified as unlikely, nine as possible, 11 as probable and four as certain. Consequently, we concluded that a causal relationship between maternal paracetamol intake and fetal ductus arteriosus constriction or closure is likely. These findings suggest that pharmacovigilance studies on paracetamol safety during pregnancy are warranted to quantify the event and put the current findings into clinical perspective. Although analgesia during pregnancy and during the peripartum period is of obvious relevance, alternative analgesics such as opioids or other nonsteroidal anti-inflammatory drugs also have side effects.

PMID- 30300945 TI - Quantitative phosphoproteomic analysis reveals common regulatory mechanisms between effector- and PAMP-triggered immunity in plants. AB - Plant immunity consists of two arms: pathogen-associated molecular pattern (PAMP) triggered immunity (PTI), induced by surface-localized receptors, and effector triggered immunity (ETI), induced by intracellular receptors. Despite the little structural similarity, both receptor types activate similar responses with different dynamics. To better understand phosphorylation events during ETI, we employed a phosphoproteomic screen using an inducible expression system of the bacterial effector avrRpt2 in Arabidopsis thaliana, and identified 109 differentially phosphorylated residues of membrane-associated proteins on activation of the intracellular RPS2 receptor. Interestingly, several RPS2 regulated phosphosites overlap with sites that are regulated during PTI, suggesting that these phosphosites may be convergent points of both signaling arms. Moreover, some of these sites are residues of important defense components, including the NADPH oxidase RBOHD, ABC-transporter PEN3, calcium-ATPase ACA8, noncanonical Galpha protein XLG2 and H+ -ATPases. In particular, we found that S343 and S347 of RBOHD are common phosphorylation targets during PTI and ETI. Our mutational analyses showed that these sites are required for the production of reactive oxygen species during both PTI and ETI, and immunity against avirulent bacteria and a virulent necrotrophic fungus. We provide, for the first time, large-scale phosphoproteomic data of ETI, thereby suggesting crucial roles of common phosphosites in plant immunity. PMID- 30300947 TI - Potentially Inappropriate Medications in Older Adults: Deprescribing with a Clinical Pharmacist. AB - OBJECTIVES: To compare the effects of a Geriatric Patient-Aligned Care Team (GeriPACT) on deprescribing of potentially inappropriate medications (PIMs) in individuals aged 80 and older with usual care (UC) in the Veterans Affairs setting. DESIGN: Retrospective cohort study. SETTING: Veterans Affairs Medical Center in Lexington, Kentucky. PARTICIPANTS: Individuals aged 80 and older who filled a PIM at least 90 days before a GeriPACT or primary care appointment between January 1, 2015, and September 6, 2017 (N = 568). MEASUREMENTS: The primary outcome was to determine whether an interdisciplinary team (IDT) including a clinical pharmacy specialist (CPS) resulted in greater deprescribing of PIMs for older adults than UC. RESULTS: One hundred twenty-one (26.8%) PIMs were deprescribed in GeriPACT, compared with 73 (16.1%) in UC (p = <.001). Of PIMs not deprescribed, 9.7% (n = 32) were dose reduced in GeriPACT, versus 2.8% (n = 11) in UC (p < .001). Documentation of risk versus benefit discussion between a provider and participant or pharmacist and participant occurred with 65.2% (n = 215) of PIMs not deprescribed in GeriPACT and 0.003% (n = 1) in UC (p < .001). CONCLUSION: An IDT that included a CPS led to significantly more deprescribing of PIMs in older veterans. Including a CPS on an IDT for the management of older adults can decrease PIM use in our rapidly growing aging population.

AB - BACKGROUND: The World Health Organization (WHO) recommends that women wait at least 24 months after a livebirth before attempting a subsequent pregnancy to reduce the risk of adverse maternal, perinatal, and infant health outcomes. However, the applicability of the WHO recommendations for women in the United States is unclear, as breast feeding, nutrition, maternal age at first birth, and total fertility rate differs substantially between the United States and the low- and middle-resource countries upon which most of the evidence is based. METHODS: To inform guideline development for birth spacing specific to women in the United States, the Office of Population Affairs (OPA) convened an expert work group meeting in Washington, DC, on 14-15 September 2017 among reproductive, perinatal, paediatric, social, and public health epidemiologists; obstetrician gynaecologists; biostatisticians; and experts in evidence synthesis related to women's health. RESULTS: Presentations and discussion topics included the methodological quality of existing studies, evaluation of the evidence for causal effects of short interpregnancy intervals on adverse perinatal and maternal health outcomes, good practices for future research, and identification of research gaps and priorities for future work. CONCLUSIONS: This report provides an overview of the presentations, discussions, and conclusions from the expert work group meeting.

AB - AIMS: To examine the relationship between workplace violence perpetrated by clients, their innate neurophysiological response to dis-ease and the resulting interactions with healthcare providers. BACKGROUND: Client-on-worker violence remains a problem globally. Workplace violence risk factors have been documented. A gap remains in understanding what has happened to clients that perpetrate violence, and the link between adverse childhood experiences (ACE), the neuroscience of threat and trauma-informed care. DESIGN: This explanatory study was part of a larger descriptive study. METHODS: Managers, directors, health/safety staff, nurses and educators (n = 99) from Australian rural and metropolitan health services participated in individual and group interviews. Following inductive thematic analysis, a secondary analysis, informed by understandings of ACE, polyvagal theory and trauma-informed care, was conducted. Analysis was guided by the question: What happens to clients that causes them to instigate violence against healthcare workers? Reporting of this research adheres to the COREQ guidelines. RESULTS: Clients can react aggressively when under perceived threat. Themes included are as follows: client stress and trauma, previous client trauma, impact of care provision on client and trauma-informed care. CONCLUSION: Healthcare services can be experienced as stressful environments. Coupled with high incidences of past trauma, clients' assessment of risk and safety can be compromised resulting in inappropriate reactivity when staff are trying to provide care. Care provision can be perceived as a threat to clients' physical and psychological safety, activating the fight protective response resulting in aggression. Understanding and applying neuroscience and implementing a cultural change of trauma-informed care have the potential to reduce workplace violence. Even with these understandings, it is imperative that healthcare staff are protected and feel safe at work. RELEVANCE TO CLINICAL PRACTICE: Understanding trauma and the neuroscience of threat and safety can assist staff to understand what happens to clients that causes them to instigate violence against healthcare providers and implement systems and strategies to respond to such threat.

AB - Sulfoximines with stereogenic sulfur atoms are attractive structural motifs in drug discovery. A direct catalytic enantioselective method for the synthesis of sulfur-chiral 1,2-benzothiazines from readily accessible diaryl sulfoximines is presented. Rhodium(III) complexes equipped with chiral cyclopentadienyl ligands and paired with suitable carboxylic acid additives engage in an enantiodetermining C-H activation directed by the sulfoximine group. Subsequent trapping of the rhodacycle with a broad range of diazoketones gives access to S chiral 1,2-benzothiazines with synthetically highly attractive substitution patterns in good yields and enantioselectivities. PMID- 30300951 TI - Analyte-Substrate Interactions at Functionalized Tip-Electrospray Ionization Mass Spectrometry: Molecular Mechanisms and Applications. AB - Conventional electrospray ionization mass spectrometry (ESI-MS) commonly uses capillary tip for sample introduction and ionization. In recent years, ESI-MS using non-capillary substrate tips has attracted growing interest as it allows separation and enrichment of analytes from complex samples due to the analytes substrate interactions. In this work, model mixtures and functionalized tips were employed to investigate the molecular mechanism of the analyte-substrate interactions. The mixtures were directly loaded on substrate tips, and then temporal responses of analytes were investigated by monitoring selected ion chromatogram (SIC) responses of each analyte. It is found that movements of bulk solution on substrate surface was firstly occurred that all analytes are sprayed out together, and then sequential ionization of analytes were observed on substrate surface which were affected by the analytes-substrate interactions in which weaker interaction were easier to be faster moved on substrate tips and the stronger interactions caused the target analyte to be retained on the substrate. The main molecular mechanisms of analyte-substrate interactions were revealed to be hydrophobic interactions and electrostatic interactions. Furthermore, based on the mechanistic insights, functionalized tips were further applied for rapid extractive sampling of target analytes from complex samples with good analytical performances. Overall, this study on the mechanism and applications of analyte substrate interactions is useful for understanding of the fundamental principles and further developments of functionalized TESI. PMID- 30300952 TI - PI3Kdelta Is a Therapeutic Target in Hepatocellular Carcinoma. AB - Class I phosphoinositide 3-kinase (PI3K) signaling is a major pathway in human cancer development and progression. Among the four PI3K isoforms, PI3Kalpha and PI3Kbeta are ubiquitously expressed, whereas PI3Kgamma and PI3Kdelta are found primarily in leukocytes. Until now, PI3K targeting in solid tumors has focused on inhibiting PI3Kalpha-mediated and PI3Kbeta-mediated cancer cell-intrinsic PI3K activity. The role of PI3Kdelta in solid tumors is unknown. Here, we evaluated the effects of PI3Kdelta using established hepatocellular carcinoma (HCC) cells, malignant hepatocytes derived from patients with advanced HCC, murine models, and HCC tissues using RNA sequencing, quantitative PCR, immunoblotting, immunofluorescence, microarray, liquid chromatography-tandem mass spectrometry, and kinase assay. We established a chemical carcinogenesis model of liver malignancy that reflects the malignant phenotype and the in vivo environment of advanced HCC. In this in vivo advanced HCC-mimic system using HCC cells treated with hydrogen peroxide (H2 O2 ), we showed that H2 O2 selectively increases PI3Kdelta activity while decreasing that of other class I PI3Ks. Blocking PI3Kdelta activity with a PI3Kdelta inhibitor or small interfering RNA-mediated PI3Kdelta gene silencing inhibited HCC-cell proliferation and dampened key features of malignant HCC, including the up-regulation of telomerase reverse transcriptase (TERT). Mechanistically, H2 O2 induced oxidative modification of the serpin peptidase inhibitor, serpin peptidase inhibitor (SERPINA3), blocking its ubiquitin-dependent degradation and enhancing its activity as a transcriptional activator of PI3Kdelta and TERT. High PI3Kdelta levels in HCC were found to correlate with poor survival rates, with human advanced HCC showing positive correlations between the protein levels of oxidized SERPINA3, PI3Kdelta, and TERT. Thus, PI3Kdelta plays significant roles in malignant liver tumors. Conclusion: Our data identify PI3Kdelta inhibition, recently approved for the treatment of human B-cell malignancies, as a potential treatment for HCC.

PMID- 30300954 TI - PHOTOIONIZATION AND PHOTOFRAGMENTATION IN MASS SPECTROMETRY WITH VISIBLE AND UV LASERS. AB - Ever since the introduction of laser technology to the field of mass spectrometry, several disciplines evolved providing solutions to challenging scientific and analytical tasks in research and industry. Among these are techniques involving multiphoton ionization such as Resonance-Enhanced Multiphoton Ionization (REMPI, R2PI) and Mass-Analyzed Threshold Ionization (MATI) spectroscopy, a variant of Zero Kinetic Energy (ZEKE) spectroscopy, that possess the ability to selectively ionize certain preselected compounds out of complex mixtures, for example, environmental matrices, with a high level of efficiency. Another key feature of multiphoton ionization techniques is the ability to control the degree of fragmentation, whereas soft ionization is most highly appreciated in most applications. In cases where rich fragmentation patterns are desired for diagnostic purposes, Photodissociation mass spectrometry (PD-MS) is applied successfully. PD-MS allows for the cleavage of selected chemical bonds. With the introduction of chromophoric labels in PD-MS, it became possible to target certain molecules or groups within a molecule. In this review article, an overview of the basic principles and experimental requirements of REMPI and MATI spectroscopy and PD mass spectrometry are given. By means of selected examples, the latest developments and application possibilities in this field over the past decade with special focus on the German research landscape are pointed out.

PMID- 30300955 TI - Highly Diastereo- and Enantioselective Synthesis of Nitrile-Substituted Cyclopropanes by Myoglobin-Mediated Carbene Transfer Catalysis. AB - A chemobiocatalytic strategy for the highly stereoselective synthesis of nitrile substituted cyclopropanes is reported. The present approach relies on an asymmetric olefin cyclopropanation reaction catalyzed by an engineered myoglobin in the presence of ex situ generated diazoacetonitrile within a compartmentalized reaction system. This method enabled the efficient transformation of a broad range of olefin substrates at a preparative scale with up to 99.9 % de and ee and up to 5600 turnovers. The enzymatic product could be further elaborated to afford a variety of functionalized chiral cyclopropanes. This work expands the range of synthetically valuable, abiotic transformations accessible through biocatalysis and paves the way to the practical and safe exploitation of diazoacetonitrile in biocatalytic carbene transfer reactions.

AB - A general efficient one-pot synthesis of S-perfluoroalkylated NH-sulfoximines from sulfides has been developed using phenyliodine diacetate (PIDA) and ammonium carbamate. Remarkable rate enhancement with trifluoroethanol was observed, presumably due to H-bonding effects. These mild and metal-free conditions are compatible with -CH2 F, -CFCl2 , -CF2 H, -CF2 Br, -C4 F9 , and -CF3 groups, in both the alkyl- and aryl series. Based on a 19 F NMR analysis, a lambda6 acetoxysulfanenitrile intermediate was proposed. PMID- 30300957 TI - Xanthocidin Derivatives from the Endophytic Streptomyces sp. AcE210 Provide Insight into Xanthocidin Biosynthesis. AB - Xanthocidin and six new derivatives were isolated from the endophytic Streptomyces sp. AcE210. Their planar structures were elucidated by 1D and 2D NMR spectroscopy as well as by HRMS. The absolute configuration of one compound was determined by using vibrational circular dichroism spectroscopy (VCD). The structural similarities of xanthocidin and some of the isolated xanthocidin congeners to the methylenomycins A, B, and C suggested that the biosynthesis of these compounds might follow a similar route. Feeding studies with isotopically labelled [13 C5 ]-l-valine showed that instead of utilizing acetyl-CoA as starter unit, which has been proposed for the methylenomycin biosynthesis, Streptomyces sp. AcE210 employs an isobutyryl-CoA starter unit, resulting in a branched side chain in xanthocidin. Further evidence for a comparable biosynthesis was given by the analysis of the genome sequence of Streptomyces sp. AcE210 that revealed a cluster of homologues to the mmy genes involved in methylenomycin biosynthesis. PMID- 30300958 TI - A reduction in compliance or activation level reduces residual force depression in human tibialis anterior. AB - AIM: We investigated if residual force depression (rFD) is present during voluntary fixed-end contractions of human tibialis anterior (TA) and whether reducing TA's activation level after active shortening could reduce rFD. METHODS: Ten participants performed fixed-end dorsiflexion contractions to a low, moderate or high level while electromyography (EMG), dorsiflexion force and TA ultrasound images were recorded. Contractions were force- or EMG-matched and after the low or high contraction level was attained, participants respectively increased or decreased their force/EMG to a moderate level. Participants also performed moderate level contractions while the TA muscle-tendon unit (MTU) was lengthened during the force/EMG rise to the reference MTU length. RESULTS: Equivalent fascicle shortening over moderate and low to moderate level contractions did not alter EMG (P = 0.45) or dorsiflexion force (P = 0.47) at the moderate level. Greater initial fascicle shortening magnitudes (1.7 mm; P <= 0.01) to the high contraction level did not alter EMG (P = 0.45) or dorsiflexion force (P = 0.30) at the subsequent moderate level compared with moderate level contractions. TA MTU lengthening during the initial force/EMG rise reduced TA fascicle shortening (-2.5 mm; P <= 0.01), which reduced EMG (-3.9% MVC; P < 0.01) and increased dorsiflexion force (3.7% MVC; P < 0.01) at the moderate level compared with fixed end moderate level contractions. CONCLUSION: rFD is present during fixed-end dorsiflexion contractions because fascicles actively shorten as force/EMG increases and rFD can be reduced by reducing the effective MTU compliance. A reduction in muscle activation level also reduces rFD by potentially triggering residual force enhancement-related mechanisms as force drops and some fascicles actively lengthen. PMID- 30300959 TI - Radical-Mediated Thiol-Ene Strategy: Photoactivation of Thiol-Containing Drugs in Cancer Cells. AB - Photoactivated drugs provide an opportunity to improve efficacy alongside reducing side-effects in the treatment of severe diseases such as cancer. Described herein is a photoactivation decaging method of isobutylene-caged thiols through a UV-initiated thiol-ene reaction. The method was demonstrated with an isobutylene-caged cysteine, cyclic disulfide-peptide, and thiol-containing drug, all of which were rapidly and efficiently released under mild UV irradiation in the presence of thiol sources and a photoinitiator. Importantly, it is shown that the activity of histone deacetylase inhibitor largazole can be switched off when stapled, but selectively switched on within cancer cells when irradiated with non phototoxic light. PMID- 30300960 TI - A Hemicyanine-Embedded Diphenylselenide-Containing Probe "HemiSe" in which SePh2 Stays Reduced for Selective Detection of Superoxide in Living Cells. AB - A simple one-step synthesis of fluorescent probe HemiSe has been developed for the detection of superoxide (O2 .- ). The probe undergoes reaction specifically with O2 .- when in the presence of other competitive ROS/RNS/metal ions. The diphenylselenide was incorporated to completely quench the fluorescence of the hemicyanine unit through the action of a photoinduced electron transfer (PET) photomechanism. However, after the addition of O2 .- , the latent fluorophore regains its fluorescence owing to the reaction at the C=C bond of the hemicyanine with O2 .- through nucleophilic attack; the increase in blue emission is due to a reaction of the double bond within HemiSe followed by an increase in fluorescence quantum yield (Phi) up to 0.45; the limit of detection (LOD) is 11.9 nm. A time dependent study shows that HemiSe can detect superoxide within 13 min with high sensitivity, high selectivity, over a wide pH range, and through confirmation with a xanthine/xanthine oxidase biochemical assay (lambdaem =439 nm). A study in the RAW 264.7 macrophage living cells also shows that HemiSe is not toxic, cell permeable (experimental log P=2.11); confocal imaging results show that HemiSe can detect O2 .- in endogenous and exogeneous systems. PMID- 30300961 TI - Periodontitis is associated with incident chronic liver disease-A population based cohort study. AB - BACKGROUND & AIMS: Chronic liver disease is a major health concern worldwide and the identification of novel modifiable risk factors may benefit subjects at risk. Few studies have analyzed periodontitis as a risk factor for liver complications. We studied whether periodontitis is associated with incident severe liver disease. METHODS: The study comprised 6165 individuals without baseline liver disease who participated in the Finnish population-based Health 2000 Survey (BRIF8901) during 2000-2001, a nationally representative cohort. Follow-up was until 2013 for liver-related admissions, liver cancer and mortality from National Hospital Discharge, Finnish Cancer Registry and Causes of Death Register, Statistics Finland. Mild to moderate periodontitis was defined as >=1 tooth with periodontal pocket >=4 mm deep, and advanced periodontitis as >=5 teeth with such pockets. Multiple confounders were considered. RESULTS: A total of 79 subjects experienced a severe liver event during follow-up. When adjusted for age, sex and number of teeth, hazards ratios by Cox regression regarding incident severe liver disease were, for mild to moderate periodontitis, 2.12 (95% CI 0.98-4.58), and, for advanced periodontitis, 3.69 (95% CI 1.79-7.60). These risk estimates remained stable after additionally adjusting for alcohol use, smoking, metabolic risk, serum gamma-glutamyltransferase, dental-care habits, lifestyle and socioeconomic status. Periodontal disease-associated liver risk was accentuated among subjects with non-alcoholic fatty liver disease or heavy alcohol use at baseline. CONCLUSIONS: Periodontitis was associated with incident liver disease in the general population independently of various confounders. As a preventable disease, periodontal disease might present a modifiable risk factor for chronic liver disease. PMID- 30300962 TI - Structural Design of Ionic Liquids for Optimizing Aromatic Dissolution. AB - Certain protic ionic liquids (PILs) are potentially low-cost, high-efficiency solvents for the extraction and processing of aromatic compounds. To understand the key design features of PILs that determine solubility selectivity at the atomic level, neutron diffraction was used to compare the bulk structure of two PILs with and without an aromatic solute, guaiacol (2-methoxyphenol). Guaiacol is a common lignin residue in biomass processing, and a model compound for anisole- or phenol-based food additives and drug precursors. Although the presence of amphiphilic nanostructure is important to facilitate the dissolution of solute nonpolar moieties, the local geometry and competitive interactions between the polar groups of the cation, anion, and solute are found to also strongly influence solvation. Based on these factors, a framework is presented for the design of PIL structure to minimize competition and to enhance driving forces for the dissolution of small aromatic species. PMID- 30300963 TI - Impact of colonoscopic screening in Familial Colorectal Cancer Type X. AB - BACKGROUND: Hereditary Non-Polyposis Colorectal cancer is caused by Lynch Syndrome (LS; an autosomal dominant condition) or by Familial Colorectal Cancer Type-X (FCCTX; a condition of high family risk that fulfills Amsterdam criteria). The lifetime risk of developing colorectal cancer (CRC) in FCCTX family members is high and CRC occurs later than in LS. METHODS: To determine the impact of primary prevention colonoscopic screening in asymptomatic first-degree relatives of incident CRC cases in 20 families with FCCTX, we compared cancer incidence and survival in 79 males and 83 females, assumed to be at 50% risk of inheriting a genetic CRC susceptibility factor, who entered screening to an unscreened control group from the families, matched for age at entry into screening and for sex. RESULTS: In males, median age at entry into screening was 44.8 years, median follow-up 12.4 years, 12% developed CRC, and 46% died after 30 years of follow up. Compared to the unscreened group, relative risk of CRC was 0.27 (95% confidence intervals (CI) 0.10-0.71). In screened females, comparable results were 44.5 years at entry, 11.2 years of follow-up, 7.1% developed CRC, and 7.2% died after 30 years of follow-up. The relative risk of CRC compared to the unscreened group was 0.19 (95% CI 0.07-0.48). CONCLUSION: Primary prevention screening colonoscopy in asymptomatic family members significantly decreased the risk of CRC in FCCTX. PMID- 30300964 TI - A review on the use of computational methods to characterize, design, and optimize tissue engineering scaffolds, with a potential in 3D printing fabrication. AB - The design and fabrication of tissue engineering scaffolds is a highly complex process. In order to provide a proper architecture for cells to grow, proliferate, and differentiate to form tissues, scaffolds have to be made with suitable properties. However, the limited structural designs and conventional fabrication techniques severely cripple the improvement of scaffold properties. To overcome these limitations, many researchers have recently adopted computational methods combined with 3D printing techniques as a new approach for scaffold design and fabrication. This approach allows scaffolds to be designed and fabricated with highly complex microstructures and good control and accuracy. Previous works have also shown this approach to be a very useful tool to predict the scaffold properties and to optimize the scaffold designs with a great reduction of experimental iterations. As this approach combining computational methods and 3D printing techniques for scaffold design and fabrication has many advantages over the conventional trial-and-error based approach, it is imperative to provide a state-of-the-art review on the topic. To this end, this article reviews the various applications of computational methods in scaffold design and simulation; it also briefly reviews the application of 3D printing techniques to fabricate the computationally designed scaffolds. Finally, the limitations and future trends of this approach are discussed. Overall, this review will enable readers to understand the benefits of using computational methods coupled with 3D printing to design and fabricate scaffolds, and thus help researchers to improve and optimize the scaffold properties for future tissue engineering research.

PMID- 30300965 TI - Epac1-/- mice have elevated baseline permeability and do not respond to histamine as measured with dynamic contrast-enhanced magnetic resonance imaging with contrast agents of different molecular weights. AB - AIM: Epac1-/- mice, but not Epac2-/- mice have elevated baseline permeability to albumin. This study extends the investigations of how Epac-dependent pathways modulate transvascular exchange in response to the classical inflammatory agent histamine. It also evaluates the limitations of models of blood-to-tissue exchange in transgenic mice in DCE-MRI measurements. METHODS: We measured DCE-MRI signal intensity in masseter muscle of wt and Epac1-/- mice with established approaches from capillary physiology to determine how changes in blood flow and vascular permeability contribute to overall changes of microvascular flux. We used two tracers, the high molecular weight tracer (Gadomer-17, MW 17 kDa, apparent MW 30-35 kDa) is expected to be primarily limited by diffusion and therefore less dependent on changes in blood flow and the low molecular weight tracer (Dotarem (MW 0.56 kDa) whose transvascular exchange is determined by both blood flow and permeability. Paired experiments in each animal combined with analytical methods provided an internally consistent description of microvascular transport. RESULTS: Epac1-/- mice had elevated baseline permeability relative to wt control mice for Dotarem and Gadomer-17. In contrast to wt mice, Epac1-/- mice failed to increase transvascular permeability in response to histamine. Dotarem underestimated blood flow and vascular volume and Gadomer-17 has limited sensitivity in extravascular accumulation. CONCLUSION: The study suggests that the normal barrier loosening effect of histamine in venular microvessels do not function when the normal barrier tightening effect of Epac1 is already compromised. The study also demonstrated that the numerical analysis of DCE-MRI data with tracers of different molecular weight has significant limitations. PMID- 30300966 TI - Cucurbit[8]uril Reactivation of an Inactivated Caspase-8 Mutant Reveals Differentiated Enzymatic Substrate Processing. AB - Caspase-8 constructs featuring an N-terminal FGG sequence allow for selective twofold recognition by cucurbit[8]uril, which leads to an increase of the enzymatic activity in a cucurbit[8]uril dose-dependent manner. This supramolecular switching has enabled for the first time the study of the same caspase-8 in its two extreme states; as full monomer and as cucurbit[8]uril induced dimer. A mutated, fully monomeric caspase-8 (D384A), which is enzymatically inactive towards its natural substrate caspase-3, could be fully reactivated upon addition of cucurbit[8]uril. In its monomeric state caspase-8 (D384A) still processes a small synthetic substrate, but not the natural caspase 3 substrate, highlighting the close interplay between protein dimerization and active site rearrangement for substrate selectivity. The ability to switch the caspase-8 activity by a supramolecular system thus provides a flexible approach to studying the activity of a protein at different oligomerization states. PMID- 30300967 TI - 3D-printed polycaprolactone scaffold mixed with beta-tricalcium phosphate as a bone regenerative material in rabbit calvarial defects. AB - Defect-specific bone regeneration using 3-dimensional (3D) printing of block bone has been developed. Polycaprolactone (PCL) is biocompatible polymer that can be used as 3D scaffold. The aim of this study is to assess the biocompatibility and osteogenic efficacy of 3D printed PCL scaffold and to evaluate the effectiveness of beta-tricalcium phosphate (beta-TCP) addition in PCL scaffold. In this work, four circular defects (diameter: 8 mm) in rabbit calvarium were randomly assigned to (1) negative control (control), (2) PCL block (PCL), (3) PCL mixed with 10 wt% beta-TCP (PCL/beta-TCP), and (4) PCL/beta-TCP plus collagen membrane (PCL/beta TCP + M). Animals were euthanized at 2 (n = 5) and 8 weeks (n = 5). Results indicated that in micro-CT, PCL/beta-TCP + M showed the highest total augmented volume and new bone volume at 8 weeks, but there was no significant difference among four groups. Histomorphometrically, PCL, PCL/beta-TCP, and PCL/beta-TCP + M showed the significantly higher total augmented area compared to the control. PCL/beta-TCP + M showed the highest new bone area but not statistically higher than the control. New bone formation deep inside the scaffold was observed only in beta-TCP added scaffold. PCL showed high biocompatibility with great volume maintenance. Addition of beta-TCP to PCL seemed to increase hydrophilicity and osteoconductivity. Developments in 3D-printed PCL material are expected. (c) 2018 Wiley Periodicals, Inc. J Biomed Mater Res B Part B: Appl Biomater, 2018. PMID- 30300969 TI - Does transanal local resection increase morbidity for subsequent total mesorectal excision for early rectal cancer? AB - AIM: Local excision is recommended for early rectal cancer (pT1). Complementary total mesorectal excision (cTME) is warranted when bad pathological features are present. The impact of a prior local resection on the outcome remains unclear. The aim of this study was to assess if prior local excision increases the morbidity of a subsequent cTME compared with primary TME. METHODS: From 2001 to 2016 all patients who underwent TME after local excision for rectal adenocarcinoma were studied. All were matched (1:1) with patients who underwent primary TME, without neoadjuvant radiochemotherapy. The matching factors included age, sex, body mass index, American Society of Anesthesiologists score and type of surgery. Short-term morbidity and pathological examination of the resected specimen were compared. RESULTS: Forty-one patients were included (14 women, 34%, mean age 65 +/- 11 years), comprising classic transanal excision (66%) and transanal endoscopic microsurgery (34%), and were matched to 41 patients who had primary TME. cTME was significantly longer (315 min +/- 87 vs 275 min +/- 58, P = 0.03). The overall morbidity was 48.8% in the local excision group vs 31.7% in the control group (P = 0.18). Surgical morbidity was 31.7% vs 26.8% (P = 0.8). Anastomotic related morbidity was similar (local excision 17% vs TME 14.6%, P = 0.84) and the mean length of stay was similar (14 days) in both groups. There was a tendency to a worse quality of mesorectal excision in the cTME group (17% vs 5%, P = 0.15). CONCLUSION: Local excision prior to TME for early rectal cancer tends to increase overall morbidity and may worsen the quality of the mesorectal plane but should be considered as a surgical approach in select cases. PMID- 30300970 TI - Continuous-flow Synthesis of Aryl Aldehydes by Pd-catalyzed Formylation of Aryl Bromides Using Carbon Monoxide and Hydrogen. AB - A continuous-flow protocol utilizing syngas (CO and H2 ) was developed for the palladium-catalyzed reductive carbonylation of (hetero)aryl bromides to their corresponding (hetero)aryl aldehydes. The optimization of temperature, pressure, catalyst and ligand loading, and residence time resulted in process-intensified flow conditions for the transformation. In addition, a key benefit of investigating the reaction in flow is the ability to precisely control the CO-to H2 stoichiometric ratio, which was identified as having a critical influence on yield. The protocol proceeds with low catalyst and ligand loadings: palladium acetate (1 mol % or below) and cataCXium A (3 mol % or below). A variety of (hetero)aryl bromides at a 3 mmol scale were converted to their corresponding (hetero)aryl aldehydes at 12 bar pressure (CO/H2 =1:3) and 120 degrees C reaction temperature within 45 min residence time to afford products mostly in good-to-excellent yields (17 examples). In particular, a successful scale-up was achieved over 415 min operation time for the reductive carbonylation of 2-bromo-6 methoxynaphthalene to synthesize 3.8 g of 6-methoxy-2-naphthaldehyde in 85 % isolated yield. Studies were conducted to understand catalyst decomposition within the reactor by using inductively coupled plasma-mass spectrometry (ICP-MS) analysis. The palladium could easily be recovered using an aqueous nitric acid wash post reaction. Mechanistic aspects and the scope of the transformation are discussed. PMID- 30300968 TI - Continued reassortment of avian H6 influenza viruses from Southern China, 2014 2016. AB - H6 subtype avian influenza virus (AIV) was prevalent in poultry and could sporadically infect humans. Here, a total of 196 novel H6 AIVs isolated from poultry in eight provinces of China from 2014 to 2016 were phylogenetically characterized. Our analysis revealed that they could be divided into two clades in the Asian H6 HA lineage, A/wild duck/Shantou/2853/2003(H6N2) (ST2853-like) (85.7%) and A/duck/Shantou/339/2000(H6N2) (ST339-like) (14.3%), in which ST2853 like strains predominate. These novel strains belonged to the H6N6 (n = 165, 84.2%), H6N2 (n = 30, 15.3%), and H6N3 (n = 1, 0.51%) subtypes, which could be classified into 36 genotypes including 12 novel genotypes described in this study. In particular, several strains possessed the V190 and S228 mutations in HA (H3 numbering), which is critical for human receptor binding and identical to the human-derived strain A/Taiwan/2/2013(H6N1). Furthermore, 10.3% of the H6N6 isolates possessed the N6-?11b (59-69) deletion. In summary, we describe phylogenetic and molecular characterizations of H6 AIVs in southern China and highlight the constant prevalence of H6 AIVs in poultry as well as adaptation to mammalian hosts.

The activity of synthetic unnatural alpha-amino acid-based organocatalysts, such as beta-alkyl alanines, alanine-based phosphines, and tert-leucine derivatives, are reviewed herein. The organocatalytic properties of unnatural monocyclic, bicyclic, and tricyclic proline derivatives are also reviewed. Several families of these organocatalysts permit the efficient and stereoselective synthesis of complex natural products. Most of the reviewed organocatalysts accelerate the reported reactions through covalent interactions that raise the HOMO (enamine intermediates) or lower the LUMO (iminium intermediates). PMID- 30300972 TI - Hydrogen-Bonding-Assisted Supramolecular Metal Catalysis. AB - The process of catalyst screening and discovery still largely relies on traditional ligand-design approaches, which suffer from complex synthetic requirements and offer limited structural diversity. On the contrary, supramolecular chemistry offers the potential to harness multiple weak secondary interactions to deliver self-assembled catalysts with diverse structures or to orient substrates to achieve enzyme-like activity and selectivity. Herein, the application of hydrogen-bonding (H-bonding) interactions as a construction element and directing group in "supramolecular transition-metal catalysis" is critically reviewed and the current state-of-the-art in the field is presented. H bonding interactions empower structurally simple ligands to deliver complex self assembled catalysts, which have been found to catalyze a gamut of organic transformations, including hydroformylation, hydrogenation, and allylation reactions. As we will discuss, on many occasions, these supramolecular catalysts outperform their analogous covalently linked catalytic systems. The potential of H-bonding interactions as directing groups has recently been recognized by the scientific community and this Focus Review presents the role of hydrogen-bonding interactions in directing substrates to obtain excellent selectivities and activities in a range of catalytic transformations.

AB - Genome mining is a routine technique in microbes for discovering biosynthetic pathways. In plants, however, genomic information is not commonly used to identify novel biosynthesis genes. Here, we present the genome of the medicinal plant and oxindole monoterpene indole alkaloid (MIA) producer Gelsemium sempervirens (Gelsemiaceae). A gene cluster from Catharanthus roseus, which is utilized at least six enzymatic steps downstream from the last common intermediate shared between the two plant alkaloid types, is found in G. sempervirens, although the corresponding enzymes act on entirely different substrates. This study provides insights into the common genomic context of MIA pathways and is an important milestone in the further elucidation of the Gelsemium oxindole alkaloid pathway. PMID- 30300975 TI - High-Voltage and Low-Temperature Aqueous Supercapacitor Enabled by "Water-in Imidazolium Chloride" Electrolytes. AB - Symmetric aqueous high voltage supercapacitors up to 3 V have been demonstrated using concentrated aqueous 1-butyl-3-methylimidazolium chloride ([BMIm]Cl), namely, "water-in-imidazolium chloride", as working electrolytes, and graphene nanoplatelets-coated carbon paper as electrodes. Performance enhancement was further achieved either through adding redox species such as 4-hydroxy-2,2,6,6 tetramethylpiperidin-1-oxyl (4hT) into the electrolytes (110 Wh kg-1 for a 20 m [BMIm]Cl/H2 O with 0.1 m 4hT) or by pre-inserting ClO4 - anions into the graphene platelets. Moreover, the newly studied aqueous electrolytes allow low-temperature operation at -20 degrees C and even at -32 degrees C, retaining competitive energy storage capability (maximum energy densities of 36 and 21 Wh kg-1 , respectively). PMID- 30300976 TI - In Situ-Fabricated 2D/2D Heterojunctions of Ultrathin SiC/Reduced Graphene Oxide Nanosheets for Efficient CO2 Photoreduction with High CH4 Selectivity. AB - Photoreduction of CO2 into fuel molecules such as CH4 represents a promising route to simultaneously explore renewable energy and alleviate global warming. However, the implementation of such a process is hampered by low product yields and poor selectivity. A 2D/2D heterojunction of ultrathin SiC and reduced graphene oxide (RGO) nanosheets was fabricated in situ for efficient and selective photoreduction of CO2 . Ultrathin SiC suppresses significant charge recombination in the bulk phase, thus providing more energetic electrons. The robust 2D/2D heterojunction allows fast transfer of energetic electrons from SiC to RGO. Combining the vital role of RGO in facilitating CO2 activation, the optimized SiC/RGO exhibits an electron-transfer rate of 58.17 MUmol h-1 g-1 towards CO2 reduction, 2.7 times that of pure SiC (20.25 MUmol h-1 g-1 ). About 92 % of the transferred electrons from SiC are devoted to generating CH4 (6.72 MUmol h-1 g-1 ). Such high efficiency and selectivity are mainly a result of the densely accumulated energetic electrons within RGO, which facilitate the eight electron process to produce CH4 . This work will inspire the design of catalyst/cocatalyst systems for efficient and selective photoreduction of CO2 . PMID- 30300977 TI - The Current State of Evidence on Bundled Payments. AB - A review of the evidence shows that bundled payments for surgical procedures can generate savings without adversely affecting patient outcomes. Less is known about the effect of bundled payments for chronic medical conditions, but early evidence suggests that cost and quality improvements may be small or non existent. There is little evidence that bundles reduce access and equity, but continued monitoring is required.

PMID- 30300979 TI - A Rare Case of Lymph Node Metastasis from Early Gastric Cancer. AB - Gastric cancers that fulfill the Japanese criteria for curative endoscopic resection show a low risk of lymph node (LN) metastasis. Here, we report a case of LN metastasis from early gastric cancer that fulfilled the curative criteria. A 74-year-old Japanese woman was referred to our hospital for treatment of early gastric cancer identified at the site of a hyperplastic polyp that had been diagnosed 10 years prior to presentation. Contrast-enhanced computed tomography did not show any lymphadenopathy and laparoscopy-assisted distal gastrectomy was performed. Histopathological examination revealed a predominantly moderately differentiated adenocarcinoma that measured 15 mm in size and was confined to the mucosa. However, a single metastatic regional LN was observed. A few cancer cells showed positive staining for alpha-fetoprotein. It should be noted that early gastric cancer can be accompanied by LN metastasis even if it fulfills the criteria for curative endoscopic resection. PMID- 30300980 TI - Buried Barrett's Esophagus with High-Grade Dysplasia after Radiofrequency Ablation. AB - Radiofrequency ablation therapy is an effective endoscopic option for the eradication of Barrett's esophagus that appears to reduce the risk of esophageal cancer. A concern associated with this technique is the development of subsquamous/buried intestinal metaplasia, whose clinical relevance and malignant potential have not yet been fully elucidated. Fewer than 20 cases of subsquamous neoplasia after the successful radiofrequency ablation of Barrett's esophagus have been reported to date. Here, we describe a new case of subsquamous neoplasia (high-grade dysplasia) following radiofrequency ablation that was managed with endoscopic resection. Our experience suggests that a meticulous endoscopic inspection prior to and after radiofrequency ablation is fundamental to reduce the risk of buried neoplasia development. PMID- 30300981 TI - Omental Patching and Purse-String Endosuture Closure after Endoscopic Full Thickness Resection in Patients with Gastric Gastrointestinal Stromal Tumors. AB - Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, primarily arising from the stomach. With the widespread utilization of and technical advancements in endoscopy, gastric GISTs are being increasingly detected at an early stage, enabling complete endoscopic resection. Endoscopic full-thickness resection (EFTR) is an advanced technique that has been recognized as a treatment tool for neoplasms in the digestive tract in selected patients. Although a number of methods are available, closing large iatrogenic defects after EFTR can be a concern in clinical practice. If this potential problem is appropriately solved, patients with gastric GISTs would be suitable candidates for resection utilizing this technique. To our knowledge, this is the first study to propose omental patching and purse-string endosuture closure following EFTR as a feasible endoscopic option in patients with gastric GISTs. PMID- 30300982 TI - Primary Gastric Small Cell Carcinoma (Presenting as Linitis Plastica) Diagnosed Using Endoscopic Ultrasound-Guided Biopsy: A Case Report. AB - Small cell carcinomas are the most aggressive, highly malignant neuroendocrine tumors; among these, gastric small cell carcinoma (GSCC) is extremely rare. Here we report a case of a patient with primary GSCC, presenting as linitis plastic, who was diagnosed using endoscopic ultrasound (EUS)-guided biopsy. With undiagnosed linitis plastica, an 80-year-old woman was referred to our institution. Abdominal computed tomography revealed irregular wall thickening extending from the gastric body to the antrum. Endoscopy suspected to have Borrmann type IV advanced gastric cancer. EUS of the stomach showed diffuse submucosal thickening of the gastric wall, mainly the antrum. EUS-guided bite-on bite biopsy confirmed the diagnosis of GSCC. In general, GSCC is difficult to diagnose and careful examination is necessary to determine the therapeutic strategy; however, EUS is particularly helpful in the differential diagnosis of a lesion presenting as linitis plastica. PMID- 30300983 TI - Single-Stage Endoscopic Stone Extraction and Cholecystectomy during the Same Hospitalization. AB - Background/Aims: The clinical impact of single-stage endoscopic stone extraction by endoscopic retrograde cholangiopancreatography (ERCP) and cholecystectomy during the same hospitalization remains elusive. This study aimed to determine the efficacy and safety of single-stage ERCP and cholecystectomy during the same hospitalization in patients with cholangitis. Methods: We retrospectively reviewed the medical records of 166 patients who underwent ERCP for mild to moderate cholangitis due to choledocholithiasis secondary to cholecystolithiasis from 2012 to 2016. Results: Complete stone extraction was accomplished in 92% of patients (152/166) at the first ERCP. Among 152 patients who underwent complete stone extraction, cholecystectomy was scheduled for 119 patients (78%). Cholecystectomy was performed during the same hospitalization in 89% of patients (106/119). We compared two groups of patients: those who underwent cholecystectomy during the same hospitalization (n=106) and those who underwent cholecystectomy during a subsequent hospitalization (n=13). In the delayed group, cholecystectomy was performed about three months after the first ERCP. There were no significant differences between the groups in terms of operative time, rate of postoperative complications, and interval from cholecystectomy to discharge. Conclusions: Single-stage endoscopic stone extraction is recommended in patients with mild to moderate acute cholangitis due to choledocholithiasis. The combination of endoscopic stone extraction and cholecystectomy during the same hospitalization is safe and feasible. PMID- 30300984 TI - Endoscopy Timing in Patients with Acute Upper Gastrointestinal Bleeding. AB - Background/Aims: The role of very early (<=12 hours) endoscopy in nonvariceal upper gastrointestinal bleeding is controversial. We aimed to compare results of very early and early (12-24 hours) endoscopy in patients with upper gastrointestinal bleeding demonstrating low-risk versus high-risk features and nonvariceal versus variceal bleeding. Methods: : This retrospective study included patients with nonvariceal and variceal upper gastrointestinal bleeding. The primary outcome was a composite of inpatient death, rebleeding, or need for surgery or intensive care unit admission. Endoscopy timing was defined as very early and early. We performed the analysis in two subgroups: (1) high-risk vs. low-risk patients and (2) variceal vs. nonvariceal bleeding. Results: : A total of 102 patients were included, of whom 59.8% underwent urgent endoscopy. Patients who underwent very early endoscopy received endoscopic therapy more frequently (p=0.001), but there was no improvement in other clinical outcomes. Furthermore, patients at low risk and with nonvariceal bleeding who underwent very early endoscopy had a higher risk of the composite outcome. Conclusion: s: Very early endoscopy does not seem to be associated with improved clinical outcomes and may lead to poorer outcomes in specific populations with upper gastrointestinal bleeding. The actual benefit of very early endoscopy remains controversial and should be further clarified. PMID- 30300985 TI - Bimodal Chromoendoscopy with Confocal Laser Endomicroscopy for the Detection of Early Esophageal Squamous Cell Neoplasms. AB - Background/Aims: This study aimed to evaluate the diagnostic accuracy of dual focus narrow-band imaging (dNBI) and Lugol'schromoendoscopy (LCE) combined with probe-based confocal laser endomicroscopy (pCLE) to screen for esophageal squamous cell neoplasms (ESCNs) in patients with a history of head and neck cancer. Methods: From March to August 2016, dNBI was performed. Next, LCE was performed, followed by pCLE and biopsy. Histology has historically been the gold standard to diagnose ESCN. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of dNBI and LCE adjunct with pCLE were determined. Results: Twenty-four patients were included. Ten ESCNs were found in 8 patients (33%). Forty percent of high-graded intraepithelial neoplasias and all low-grade intraepithelial neoplasias were overlooked by dNBI. The sensitivity, specificity, PPV, NPV, and accuracy of dNBI vs. LCE combined with pCLE were 50% vs. 80%, 62% vs. 67%, 36% vs. 44%, 75% vs. 91%, and 83% vs. 70%, respectively. Conclusions: The use of dNBI to detect ESCN was suboptimal. LCE with pCLE following dNBI had additional value for detecting esophageal dysplasia not detected by dNBI. The use of pCLE to detect dNBI-missed lesions yielded a high NPV, while pCLE-guided biopsy could reduce the number of unnecessary biopsies. PMID- 30300987 TI - Intussusception after Colonoscopy: A Case Report and Review of Literature. AB - Intussusception after colonoscopy is an unusual complication. A MEDLINE search revealed only 7 reported cases. We present a report of a 28-year-old man who developed abdominal pain several hours after routine colonoscopy and in whom computed tomography (CT) revealed colocolic intussusception. We postulate that this condition is iatrogenic and induced by suctioning of gas on withdrawal of the colonoscope. A common observation among the reported cases was abdominal pain several hours after colonoscopy and right-sided intussusception. All cases had colonoscopy reaching the right side of the colon. Treatment for adult intussusception remains controversial with regard to reduction versus resection, especially given the high association with a pathological cause and malignancy. Among the 8 reported cases, only the current case did not require surgery. A combination of benign colonoscopy, CT, and the clinical picture should provide sufficient information to initially choose a more conservative treatment approach. PMID- 30300986 TI - First Characterization with Ultrasound Contrast Agent of a Fibrovascular Polyp Before Its Endoscopic Resection: A Case Report (with Videos). AB - We described for the first time the contrast enhancement of a giant fibrovascular esophageal polyp using ultrasound contrast agent, Sonovue(r) (Bracco, Milan, Italy) during echoendoscopy. Fine Doppler was unsuccessful in showing vascularization due to the mobile characteristic of the tumor. In contrast, via Sonovue(r) , tissue microcirculation was highlighted inside the entire head of the polyp, leading to better appreciate the risk of bleeding related to its resection. In a second part, we showed the feasibility of classic polypectomy for this giant polyp (5*5 cm) without complication and results of control endoscopy at 3 months. The present case is summarized in a video. PMID- 30300988 TI - Mucosal Changes in the Small Intestines in Portal Hypertension: First Study Using the Pillcam SB3 Capsule Endoscopy System. AB - BACKGROUND/AIMS: To evaluate patients with portal hypertension (PH) of varied etiologies for portal hypertensive enteropathy (PHE) using the PillCam SB3 capsule endoscopy (CE) system. METHODS: Consecutive patients with PH presenting with unexplained anemia and/or occult gastrointestinal bleeding were evaluated using the PillCam SB3 CE system. Abnormal findings were categorized as vascular or non-vascular. The patients with ongoing bleeding caused by PHE were treated. The correlation of the CE scores of PHE with the clinical, laboratory, and endoscopic features was determined. RESULTS: Of the 43 patients included in the study, 41 (95.3%) showed PHE findings. These included varices (67.4%), red spots (60.5%), erythema (44.2%), villous edema (46.5%), telangiectasia (16.3%), and polyps (16.3%). The CE scores varied from 0 to 8 (mean+/-standard deviation, 4.09+/-1.8). Five patients (11.6%) showed evidence of ongoing or recent bleeding due to PHE. Three of these five patients underwent endotherapy, and one patient underwent radiological coil placement. CONCLUSION: The PillCam SB3 CE system revealed a high prevalence of PHE in the patients with PH. Using this system, evidence of bleeding due to PHE was found in a small but definite proportion of the patients. PMID- 30300989 TI - Renovations Needed: the FDA's Floor/Ceiling Framework, Preemption, and the Opioid Epidemic. AB - The FDA's regulatory framework for pharmaceuticals uses a "floor/ceiling" model: administrative rules set a "floor" of minimum safety, while state tort liability sets a "ceiling" of maximum protection. This model emphasizes pre-market scrutiny but largely relies on the state common law "ceiling" to police the postapproval drug market. As the Supreme Court increasingly holds state tort law preempted by federal administrative standards, the FDA's framework becomes increasingly imbalanced. In the face of a historic prescription medication overdose crisis, the Opioid Epidemic, this imbalance allows the pharmaceutical industry to avoid internalizing the public health costs of their opioid products. This Note argues that the FDA's administrative design misallocates the costs of the Opioid Epidemic and fails to adequately compensate those injured by it. Part I summarizes the FDA's regulatory framework with respect to opioid medications. Part II explains how that framework creates a compensatory problem that prevents the internalization of negative externalities by pharmaceutical manufacturers. Part III proposes a victims' compensation fund as the best substitute for the functions long performed by state tort liability. PMID- 30300990 TI - Fatigue and weakness hinder patient social reintegration after liver transplantation. AB - Background/Aims: With improvements in the survival of liver transplantation (LT) recipients, the focus is shifting to patient quality of life (QOL), and employment is an important factor in aiding the social reintegration of LT patients. This study aims to evaluate the current employment status of liver graft recipients and various factors that may hinder reemployment. Methods: Fifty patients above age 18 who underwent either living or deceased donor LT at a single center from March 2009 to July 2016 were interviewed during their visit to the outpatient clinic. The internally developed questionnaire consisted of 10 items. The Karnofsky Performance Scale and EQ-5D were used to evaluate patient function and QOL. Results: A total of 25 (50%) patients returned to work after transplantation (the working group), and 21 (84%) patients in the working group returned to work within the first year after transplantation. In the non-working group (n=25), 17 (68%) answered that their health was the reason for unemployment. Fatigue and weakness were the most frequent symptoms. Conclusions: The data shows that as many as 50% of total patients returned to work after receiving LT. Fatigue and weakness were the most common complaints of the unemployed group, and resolving the causes of these symptoms may help to increase the employment rate. PMID- 30300991 TI - Pathologic differential diagnosis of metastatic carcinoma in the liver. AB - The liver is one of the most common sites to which malignancies preferentially metastasize. Although a substantial number of liver malignancies are primary tumors, including hepatocellular carcinoma and intrahepatic cholangiocarcinoma, the metastasis of carcinomas to the liver is relatively common and frequently encountered in clinical settings. Representative carcinomas that frequently metastasize to the liver include colorectal carcinoma, breast carcinoma, neuroendocrine tumors, lung carcinoma, and gastric carcinoma. The diagnostic confirmation of suspected metastatic lesions in the liver is generally achieved through a histopathologic examination of biopsy tissues. Although morphology is the most important feature for a pathologic differential diagnosis of metastatic carcinomas, immunohistochemical studies facilitate the differentiation of metastatic carcinoma origins and subtypes. Useful immunohistochemical markers for the differential diagnosis of metastatic carcinomas in the liver include cytokeratins (CK7, CK19, and CK20), neuroendocrine markers (CD56, synaptophysin, and chromogranin A), and tissue-specific markers (CDX2, SATB2, TTF-1, GCDFP-15, mammaglobin, etc.). Here, we provide a brief review about the pathologic differential diagnosis of major metastatic carcinomas in the liver. PMID- 30300992 TI - Metal concentrations in the beach sediments of Bahia Solano and Nuqui along the Pacific coast of Choco, Colombia: A baseline study. AB - Thirty sediment samples from four different beaches along Bahia Solano and Nuqui (Department of Choco) of eastern Colombia, with tourism and gold mining activities, were analysed to estimate the concentrations of fourteen different acid leachable metals. Metal distribution patterns showed elevated concentrations of Co, Cr, Cu, Pb and Zn compared with the upper continental crust values. Calculation of geochemical indices confirmed that the enrichment is due to periodic gold mining activities (severe to extremely severe enrichment of Cu, Zn, V, Co, Cr and Pb) along with natural (geological) contributions (minor and moderate enrichment of Ca, Mg, Fe, Ti, Mn and Li). Potential ecological risk index revealed that Pb posed the highest risk. Our results together with a global comparison suggest that the observed metal enrichments are mainly caused by mining and to a lesser extent by tourism in this region, thus instigating continuous monitoring of metal concentrations in this region. PMID- 30300993 TI - Marine benthic communities affected by the Doce River (southwestern Atlantic): Baseline before a mining disaster. AB - Prior to Brazil's worst environmental disaster, caused by a mining dam collapse, we had carried out a study of the marine benthic macrofauna (11-51 m depth) under the influence of the Doce River. Our results showed significant diversity, in which mollusks, polychaetes, and crustaceans had the highest frequency, density, and abundance, represented by 162 families in summer and 173 in winter. Our results suggested that richness, abundance, and diversity increase with distance from the coast. Furthermore, with increasing distance from the coast and river mouth, in addition to increasing depth, there was a differentiation in composition and abundance. Multivariate analyses showed depth, carbonate, and organic matter as important factors that explain variations in composition and diversity across the continental shelf. The results could provide an invaluable baseline for measuring the effects on shallow and mesophotic communities of one of the largest tailings dam failures worldwide.

AB - Three cores collected in the area of 16th July 2010 oil spill by box crab in May 2013 and July 2014 at the Dalian Bay have been geochemically characterized to investigate the fate of chemical components in sediments. The total organic carbon, extractable organic matter contents and biomarker compositions have been applied for the differentiation of alien organic matters from in situ ones and evaluation of the biodegradation impact. Multivariate statistical analysis suggests four groups of sediments. Except a few samples at deepest part of BQ050, majority samples have certain affinity with the spilled oil. The most contaminated sediments occur at site BQ050 and the spilled oil has migrated to 8 12 cm depth. The degree of contamination can be ranked by the similarity of molecular compositions with spilled oil. Variable biomarker components in sediment extracts were also altered by ongoing biodegradation. PMID- 30300995 TI - A study of the environmental factors influencing the growth phases of Ulva prolifera in the southern Yellow Sea, China. AB - Macroalgal blooms of U. prolifera in the southern Yellow Sea (SYS) have become an ecological disaster. In this study, we attempt to explore the influence of environmental factors and human activity on the annual development of U. prolifera during 2011-2016, combining geostationary ocean color imager images and monitored environmental factors. Blooms of U. prolifera were mainly distributed in the central SYS, drifting from the southern Yellow Sea Radial Sand Ridges. Three growth phases were defined (initial phase, outbreak phase and dissipation phase) to facilitate analysis of the relationship between the environmental factors and growth conditions of U. prolifera. Seaweed cultivation, sea surface temperature (SST) and available radiation influenced the algal biomass during the initial phase; the seawater transparency, precipitation and wind activity affected the algae during the outbreak phase; and SST, intense radiation and cleanup operations increased the rate of algal extinction in the dissipation phase. PMID- 30300996 TI - Long-term variations and influence factors of nutrients in the western North Yellow Sea, China. AB - This study investigated the long-term variations and compositions of nutrients and the associated controlling factors in the western North Yellow Sea on the basis of historical data. The NO3-N and DIN concentrations and N/P showed continuous increases over the past two decades, which were dominantly affected by riverine inputs, such as inputs from the Yellow River, Yalujiang River and Jia River and atmospheric deposition. However, due to human activities, such as dam construction in rivers and climate change, the SiO3-Si concentrations and Si/P ratios decreased before the early 1990s and then gradually increased. The vertical distributions of nutrients displayed higher concentrations at the bottom than those at the surface in summer, which was attributed to the combined influence of the thermocline, the Yellow Sea Cold Water Mass, the Yellow Sea Warm Current and biological activities. PMID- 30300997 TI - Distribution and enrichment of trace metals in surface marine sediments collected by the manned submersible Jiaolong in the Yap Trench, northwest Pacific Ocean. AB - In this study, we carried out grain size and heavy metal analyses and also assessed heavy metal enrichment and ecological risk indices in ten sediment samples collected by the manned submersible Jiaolong at different segments of the Yap Trench. The results showed that the sediments in the Yap Trench were mainly slumping deposits composed of sandy silt. Heavy metals in the sediments showed different spatial distribution patterns from north to south direction of the trench. The distribution pattern of these heavy metals also differed in the eastern and western flanks of the trench. From the results of the enrichment factors, only arsenic, chromium, and manganese showed a slight enrichment. However, all elements were affected by natural factors. Further, most elements showed a low ecological risk, and only arsenic showed a moderate risk at two stations. Finally, the potential ecological risk of the whole study area was at a low level. PMID- 30300998 TI - Mapping widespread and increasing underwater noise pollution from acoustic deterrent devices. AB - Acoustic deterrent devices (ADDs) are used in attempts to mitigate pinniped depredation on aquaculture sites through the emission of loud and pervasive noise. This study quantified spatio-temporal changes in underwater ADD noise detections along western Scotland over 11 years. Acoustic point data ('listening events') collected during cetacean line-transect surveys were used to map ADD presence between 2006 and 2016. A total of 19,601 listening events occurred along the Scottish west coast, and ADD presence was recorded during 1371 listening events. Results indicated a steady increase in ADD detections from 2006 (0.05%) to 2016 (6.8%), with the highest number of detections in 2013 (12.6%), as well as substantial geographic expansion. This study demonstrates that ADDs are a significant and chronic source of underwater noise on the Scottish west coast with potential adverse impacts on target (pinniped) and non-target (e.g. cetaceans) species, which requires further study and improved monitoring and regulatory strategies. PMID- 30300999 TI - Plastic levels in sediments closed to Cecina river estuary (Tuscany, Italy). AB - This study focuses on plastic distribution levels (shape, size, colour, type) in sediments from the coastal area of Cecina (Tuscany, Italy). Samples are collected in three sampling stations along six transect settled randomly along the shoreline and along the final tract of the Cecina river. Recorded plastic size ranges within 62.51-13,462 MUm (average values 1591 +/- 837 MUm). Microplastics (<5000 MUm) represent over than 97% of the total even if mesoplastics (5000 25,000 MUm) are also recorded (2%). Over than 60% of recorded plastic items are higher than 500 MUm. Measured levels range within 72 (ST2)-191 (ST4) items/kg d.w. Fragment > Fiber > Granule in each of the tested sampling site. Plastic litter levels recorded in study evidence low pollution compared to the existing literature supporting the occurrence of good environmental levels in Cecina coastline for the "Marine litter" descriptor. PMID- 30301000 TI - Baseline radionuclide concentration in selected marine organisms around the coastal areas of Ratnagiri and Sindhudurg districts, west coast of Maharashtra, India. AB - The present work deals with assessment of baseline radionuclide concentration in marine organisms around selected coasts of Maharashtra, India. This baseline study highlights concentrations of natural and fallout radionuclides in finfish and shellfish species found in the surrounding seawater. Water and fish samples were collected, processed, and analyzed for 238U, 226Ra, 228Ra, 232Th, 40K, and 137Cs by high-resolution gamma spectrometry. 238U, 226Ra, 228Ra, 232Th, 40K, and 137Cs concentrations were found to be in the range of <=1.5, <=2.0, <=0.4, <=1.5, <=8.0 to 258, and <=0.2 Bq/kg, respectively. The seasonal study revealed the maximum concentration in premonsoon season. Activity concentrations were higher in pelagic fish than those in demersal fish. A higher concentration factor was reported in shellfish than in finfish. PMID- 30301001 TI - Long term development of Bathing Water Quality at the German Baltic coast: spatial patterns, problems and model simulations. AB - Bathing water quality plays a key role for public health, is highly important for recreational tourism and therefore monitored in the EU-Directive 2006/7/EC. To identify pollution hot spots, sources and impacts of the directive-change in 2006, including a change of indicator organisms, we evaluated monitoring data of the past 15 years, collected own data, determined survival rates of indicator organisms and applied hydrodynamic modelling in a micro-tidal-system. Due to higher survival rates under turbid conditions and restricted water exchange, shallow, eutrophic bays and lagoons are hot spots of microbial pollution. Rain events cause high microbial emission and distribution. Based on different decay rates, the ratio of E. coli to Enterococci can hint towards a pollution source. Including rain predictions, currents and winds, hydrodynamic models can then assess the daily risk of microbial pollution at each bathing site. They are an important tool to modify beach management and event-based monitoring. PMID- 30301003 TI - Bioaccumulation of 2,4,6-trinitrotoluene (TNT) and its metabolites leaking from corroded munition in transplanted blue mussels (M. edulis). AB - Bioaccumulation of 2,4,6-trinitrotoluene (TNT) and its main metabolites 2-amino 4,6-dinitrotoluene (2-ADNT) and 4-amino-2,6-dinitrotoluene (4-ADNT) leaking from corroded munitions at a munitions dumping site (Kolberger Heide, Germany) was evaluated in transplanted blue mussels (Mytilus edulis). Six moorings with mussel bags were placed east and west at varying positions near the mine mound. In order to monitor any differences resulting from changing seasons, three exposure times were chosen. First exposure period: April-July 2016 (106 days); second exposure period: July-December 2016 (146 days); third exposure period: December 2016-March 2017 (92 days). We found amounts of 4-ADNT in mussel tissue ranging from 2.40 +/- 2.13 to 7.76 +/- 1.97 ng/(g mussel wet weight). Neither TNT nor 2-ADNT could be detected. Considering seasonal differences, orientation and distances of the moorings to the mine mound no correlation between levels in mussel tissue was evident. PMID- 30301002 TI - Comparative feeding rates of native and invasive ascidians. AB - Ascidians have a recent history of species introductions globally, often with strong ecological impacts. Comparisons of per capita effects of invaders and comparable natives are useful to assess such impacts. Here, we explore ingestion rates (IR) and clearance rates (CR) of Ciona intestinalis and Ciona robusta, co occurring native and non-native ascidians, respectively, from Brittany, France. IR was positively related to food concentration, with the invader responding more strongly to increasing food concentration. CR also differed by species, with the invader demonstrating higher values. C. robusta exhibited a higher functional response (Type I) than did C. intestinalis (Type II). Relative impact measured using seasonal abundance and IR revealed that C. robusta has a much greater impact than C. intestinalis at all food concentrations tested, though the former has a constrained distribution which limits its regional impact. Nevertheless, when abundant, we expect C. robusta to exert a greater impact on algal foods.

AB - We investigated the presence of 66 human and veterinary pharmaceuticals from seven therapeutic groups in surface waters of the Tejo estuary. Collection sites covered the entire estuary and included areas near main river inflows and wastewater treatment outfalls, traversing urban, agriculture, aquaculture, and nature reserve areas. Detection of pharmaceuticals was performed via UHPLC-TOF MS. Pharmaceuticals were found in all sites (32 different compounds in total). Antibiotics, beta-blockers, antihypertensives and anti-inflammatories were the most frequently detected (>90%), with variation in concentrations reflecting the multifaceted nature of estuarine surroundings (accumulated site contamination between 15 and 351 ng L-1). Higher concentrations of antidepressant Sertraline (304 ng L-1), non-steroidal anti-inflammatory Diclofenac (51.8 ng L-1), lipid regulator Gemfibrozil (77.0 ng L-1), antihypertensive Ibersartan (161.9 ng L-1) or antibiotic Doxycycline (128.0 ng L-1), among others, though localized may potentially impact key estuarine functions or services. Ultimately, results provide a baseline for regulatory information and future biota evaluations. PMID- 30301005 TI - Thalassia testudinum as a potential vector for incorporating microplastics into benthic marine food webs. AB - Seagrasses are among the most productive shallow water ecosystems, serving a diverse assemblage of fish and invertebrates. Tropical seagrass communities are dominated by the turtle grass Thalassia testudinum, whose wide, flattened blades host diverse epibiont communities. Amidst its epibionts, T. testudinum may also be accumulating microplastics, which are a ubiquitous marine pollutant even in remote locales. To assess the extent of microplastic accumulation, seagrass samples were collected from Turneffe Atoll, which lies offshore but parallel with a major urban center. Seventy-five percent of Thalassia blades had encrusted microplastics, with microfibers occurring more than microbeads and chips by a ratio of 59:14. Grazers consumed seagrasses with higher densities of epibionts. Potential mechanisms for microplastic accumulation include entrapment by epibionts, or attachment via biofilms. This study is the first to document microplastics on marine vascular plants, suggesting that macroherbivory is a viable pathway for microplastic pollution to enter marine food webs. PMID- 30301006 TI - UV fluences required for compliance with ballast water discharge standards using two approved methods for algal viability assessment. AB - This study investigates the extra UV fluence needed to meet the International Maritime Organisation's ballast water discharge standards for the 10-50 MUm size class using the approved vital stain (VS) method compared to the Most Probable Number (MPN) method for organism viability assessment. Low- and medium pressure UV collimated beam treatments were applied to natural algae collected in temperate and tropical water environments and analysed using both methods. About 10 times higher UV fluence was required to meet discharge standards when using VS compared to MPN. Implementing a dark-hold period after UV treatments decreased algal viability. Length of dark-hold period to meet discharge standards decreased with increasing UV fluence. No significant differences between temperate and tropical samples were observed. The results showed that UV treated algae assessed using the VS method could meet discharge standards by increasing fluence and/or introducing a dark-hold period. PMID- 30301007 TI - Biochemical and molecular responses in oysters Crassostrea brasiliana collected from estuarine aquaculture areas in Southern Brazil. AB - Biochemical and molecular responses were evaluated in oysters Crassostrea brasiliana collected from three oyster farms, at Guaratuba Bay, southern Brazil, forming a pollutant gradient: Farm 1 (reference site - farther from the urban area), Farm 2 (intermediate site) and Farm 3 (nearest to the urban area). Oxidative stress markers, DNA damage and transcript levels of CYP2AU1, CYP2 like1, CYP2-like2, SULT-like, GPx-like, SOD-like, CAT-like, GSTmicrosomal-like, GSTomega-like, FABP-like and ALAd-like genes were analyzed in the gills. The levels of polycyclic aromatic hydrocarbons, linear alkylbenzenes and polychlorinated biphenyls were also evaluated in the soft tissues of the oysters and in the sediment of the Farms. Higher GSTomega-like, CYP2AU1 and FABP-like transcript levels, GR and G6PDH activities and lipid peroxidation levels were observed in oysters from Farms 2 and 3, suggesting pollutant effects on oysters. Alterations in oxidative stress markers also suggest a response against a prooxidant condition in C. brasiliana due to pollutant effects. PMID- 30301008 TI - Mercury concentrations in muscles and liver tissues of Cape monkfish (Lophius vomerinus) from the Northern Benguela, Namibia. AB - Cape monkfish (Lophius vomerinus) is one of the long-lived species and top predators in the northern Benguela region. Studies on bioaccumulation of mercury (Hg) in cape monkfish are limited. This study compared the total Hg concentration between monkfish muscle and liver tissue; and related the monkfish total Hg concentrations to fish body size and capture locations (depth and latitude). Monkfish specimens (n = 529) were collected from 2016 to 2018. The mean total Hg concentration was 0.126 +/- 0.005 mg/kg in muscle tissues and 0.106 +/- 0.005 mg/kg in liver tissues. No significant differences were observed between total Hg concentrations of muscles and liver tissues. Differences in Hg concentrations between monkfish length classes were observed. No significant correlation was found between total Hg concentrations and latitude. A significant increase of total Hg concentration with the depth was observed. The concentrations of Hg were below the World Health Organization (WHO limits for fish (0.5 mg/kg). PMID- 30301009 TI - Pollution and coral damage caused by derelict fishing gear on coral reefs around Koh Tao, Gulf of Thailand. AB - Most lost fishing gear is made of non-biodegradable plastics that may sink to the sea floor or drift around in currents. It may remain unnoticed until it shows up on coral reefs, beaches and in other coastal habitats. Stony corals have fragile skeletons and soft tissues that can easily become damaged when they get in contact with lost fishing gear. During a dive survey around Koh Tao, a small island in the Gulf of Thailand, the impact of lost fishing gear (nets, ropes, cages, lines) was studied on corals representing six different growth forms: branching, encrusting, foliaceous, free-living, laminar, and massive. Most gear (>95%) contained plastic. Besides absence of damage (ND), three categories of coral damage were assessed: fresh tissue loss (FTL), tissue loss with algal growth (TLAG), and fragmentation (FR). The position of the corals in relation to the fishing gear was recorded as either growing underneath (Un) or on top (On), whereas corals adjacent to the gear (Ad) were used as controls. Nets formed the dominant type of lost gear, followed by ropes, lines and cages, respectively. Branching corals were most commonly found in contact with the gear and also around it. Tubastraea micranthus was the most commonly encountered coral species, either Un, On, or Ad. Corals underneath gear showed most damage, which predominantly consisted of tissue loss. Fragmentation was less common than expected, which may be related to the low fragility of T. micranthus as dominant branching species. Even if nets serve as substrate for corals, it is recommended to remove them from reefs, where they form a major component of the plastic pollution and cause damage to corals and other reef organisms. PMID- 30301010 TI - An ecological risk assessment model for Arctic oil spills from a subsea pipeline. AB - There is significant risk associated with increased oil and gas exploration activities in the Arctic Ocean. This paper presents a probabilistic methodology for Ecological Risk Assessment (ERA) of accidental oil spills in this region. A fugacity approach is adopted to model the fate and transport of released oil, taking into account the uncertainty of input variables. This assists in predicting the 95th percentile Predicted Exposure Concentration (PEC95%) of pollutants in different media. The 5th percentile Predicted No Effect Concentration (PNEC5%) is obtained from toxicity data for 19 species. A model based on Dynamic Bayesian Network (DBN) is developed to assess the ecological risk posed to the aquatic community. The model enables accounting for the occurrence likelihood of input parameters, as well as analyzing the time-variable risk profile caused by seasonal changes. It is observed through the results that previous probabilistic methods developed for ERA can be overestimating the risk level. PMID- 30301011 TI - Widespread recovery of seagrass coverage in Southwest Florida (USA): Temporal and spatial trends and management actions responsible for success. AB - In Southwest Florida, a variety of human impacts had caused widespread losses of seagrass coverage from historical conditions. St. Joseph Sound and Clearwater Harbor lost approximately 24 and 51%, respectively, of their seagrass coverage between 1950 and 1999, while Tampa Bay and Sarasota Bay had lost 46% and 15%, respectively, of their seagrass coverage between 1950 and the 1980s. However, over the period of 1999 to 2016, the largest of the six estuaries, Tampa Bay, added 408 ha of seagrass per year, while the remaining five estuaries examined in this paper added approximately 269 ha per year. In total, seagrass coverage in these six estuaries increased 12,171 ha between the 1980s and 2016. Focused resource management plans have held the line on nitrogen loads from non-point sources, allowing seagrass resources to expand in response to reductions in point source loads that have been implemented over the past few decades. PMID- 30301012 TI - Heavy metal distribution, contamination and analysis of sources - Intertidal zones of Sandu Bay, Ningde, China. AB - Concentrations of heavy metals in sediments and seawaters from the intertidal zone are analyzed along with cage-bred fish in the Sandu Bay of Fujian Province in China. Elements measured are As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn. The concentrations of Cu and Ni found in the sediments do not meet the first standard of the Chinese National Criteria for Marine Sediment Quality. The results of Igeo, EF, and CF index calculations for the sediment samples clearly prove anthropogenic causes of contamination. The water quality standard for fisheries was exceeded by As, Hg, and Cu. Cage-bred fish show increased levels of As, Cr, and Zn. Significant associations are found for AsCu and NiZn. These findings can be related to coal and crude oil combustion and processes associated with the production of batteries, steel, and alloys. The results point to industrial source locations along discharging rivers north and northwest of the Sandu Bay. PMID- 30301013 TI - Proof of concept for a model of light reflectance of plastics floating on natural waters. AB - Remote sensing of plastic littering natural waters is an emerging field of science with the potential to provide observations on local to global scales. We present the verification of a theoretical reflectance model of sunlight interacting with a water surface littered with buoyant plastic objects. We measured a few common litter items of different polymers as well as shapes, transparencies, and surface roughnesses. Spectral reflectance measurements in the field were backed up with measurements in the laboratory of coefficients of total and diffuse reflectance, transmittance and absorption. We evaluated a single-band algorithm for 850 nm wavelength and a dual-band algorithm using a second wavelength at a polymer absorption band between 1660 and 1730 nm. Both algorithms were plastic litter type specific. Our findings show that for interpreting spectral remote sensing of floating plastic, physical properties that control geometrical optics should complement information about the absorption spectra of the polymer. PMID- 30301014 TI - Decadal and spatial variation of Hg concentrations in sediments of a multi stressor impacted estuary. AB - The present study has evaluated temporal and spatial mercury trends based on surficial sediment samples and 210Pb-dated sediment profiles. The obtained results show that there are areas close to the main bay's tributary rivers where the Hg content has doubled during the last 15 years and regions where it has decreased by a factor of 2, mainly the area close to the navigation channel, which is submitted to periodic dredging. In the inner part of the bay, the most contaminated region, mercury shows a strong association with sulfide. In the same region, based on the 210Pb results, it was possible to calculate the yearly increment on the Hg concentration in the surface sediment, 0.62 MUg kg-1 y-1 to 0.29 MUg kg-1 y-1, according to the distance to the bay's main tributary rivers. PMID- 30301015 TI - Numerical modelling of mercury evasion in a two-layered Adriatic Sea using a coupled atmosphere-ocean model. AB - A new mercury (Hg) evasion model for the Adriatic Sea was developed accounting for the ocean mixed layer depth in order to decrease Hg depletion at the surface. Previously modelled airborne Hg species and measured Hg in the ocean were used. Simulations were run using one- and two-way coupled atmosphere-ocean models. Discrepancies in evasion between the applied coupling schemes were shown to be insignificant. The model was evaluated by applying various wind parameterisations and diffusive coefficient formulae. Relatively high discrepancies among the applied methods were observed. The results of a shorter simulation were extrapolated over a one-year period by applying a measurement-based adaptation. We obtained good agreement with previously published data on Hg evasion in the entire Mediterranean area, thus confirming the suitability of the new model for Hg evasion simulations. Model computations performed for the Adriatic Sea resulted in levels of evasion approximately two times lower than previously estimated. PMID- 30301016 TI - Root activities and arsenic translocation of Avicennia marina (Forsk.) Vierh seedlings influenced by sulfur and iron amendments. AB - Sulfur and iron are abundant and have close, complex interactions with the biogeochemical cycle of arsenic (As) in mangrove ecosystems. A hydroponic experiment was conducted to investigate the influences of variable SO42- and Fe2+ supplies on radial oxygen loss (ROL), iron plaque formation and As translocation in Avicennia marina upon exposure to As(III). The results indicate that A. marina is an As-tolerant plant, the application of iron and sulfur not only showed positive growth effects but also induced much higher amounts of ROL-induced iron plaque formation on root surfaces. The presence of iron plaque remarkably improved the proportion of As sequestration near this area but consequently reduced the proportion of As translocation in root. Therefore, it is concluded that iron plaque may act as a barrier for protection against As, and iron and sulfur play important roles in controlling the growth and translocation of As in A. marina seedlings. PMID- 30301017 TI - Assessing the impacts of seabed mineral extraction in the deep sea and coastal marine environments: Current methods and recommendations for environmental risk assessment. AB - Mineral extraction from the seabed has experienced a recent surge of interest from both the mining industry and marine scientists. While improved methods of geological investigation have enabled the mapping of new seafloor mineral reserves, the ecological impacts of mining in both the deep sea and the shallow seabed are poorly known. This paper presents a synthesis of the empirical evidence from experimental seabed mining and parallel industries to infer the effects of seabed mineral extraction on marine ecosystems, focusing on polymetallic nodules and ferromanganese concretions. We use a problem-structuring framework to evaluate causal relationships between pressures caused by nodule extraction and the associated changes in marine ecosystems. To ensure that the rationale behind impact assessments is clear, we propose that future impact assessments use pressure-specific expert elicitation. We further discuss integrating ecosystem services in the impact assessments and the implications of current methods for environmental risk assessments. PMID- 30301018 TI - Study of the oil interaction towards oil spill recovery skimmer material: Effect of the oil weathering and emulsification properties. AB - The primary aim of this research was to identify the physicochemical properties of the oil and water-in-oil (W/O) emulsions used during a NOFO Oil-on-Water field trials that reduced the performance of the skimmers recovery efficacy during the trials. Extensive studies were performed at SINTEF laboratories with the residues of oil topped (i.e. evaporative loss of crude oil components by distillation process at large scale) for the field trial and compared it with different residues of oil topped by bench scale laboratory procedures. In order to obtain a sufficient stable W/O emulsion for the field trial, bunker fuel oil (IFO380) and various concentrations of an emulsifier (Paramul(r)) were also added to the residues of oil topped on large scale and investigated through interfacial tension, contact angle, droplet adhesion and "dip and withdraw" tests. The investigations revealed that the addition of an emulsifier lowered the interfacial tension of oil residues, which consequently reduced the adherence properties of the oil and emulsions to the surface of the skimmer material. Too high concentration of an emulsifier (>0,5%) also had a negative effect on the stability of W/O emulsion.

AB - The North Yellow Sea is a major aquaculture production area for the scallop Patinopecten yessoensis. In this study, the temporal and spatial variation of phycotoxins in scallops, phytoplankton, and their cysts were analyzed during a survey conducted from June 2011 to April 2012 around Zhangzi Island. The study area is a semi-enclosed epicontinental sea surrounded by the Shandong Peninsula, the Liaodong Peninsula and the Korean Peninsula. The three main results of the study were as follows: (1) The saxitoxin-group toxins, okadaic acid and analogues, and pectenotoxins were the major phycotoxin residues found in scallops; (2) Six kinds of toxic microalgae were identified, Protoperidinium spp., Gonyaulax spp., and Alexandrium spp. were the dominant taxa; Seven types of potential marine toxin-producing dinoflagellates, A. tamarense, A. catenella, Dinophysis fortii, G. catenatum, Gambierdiscus toxicus, Azadinium poporum, and Pseudo-nitzschia pungen were identified as the primary source of phycotoxins and were present at relatively high density from June to October; and (3) azaspiracids and domoic acid might be new potential sources of toxin pollution. This study represents the first assessment to phycotoxins around Zhangzi Island in the North Yellow Sea. PMID- 30301020 TI - Fine sediment and particulate organic matter: A review and case study on ridge-to reef transport, transformations, fates, and impacts on marine ecosystems. AB - Studies documenting the effects of land-derived suspended particulate matter (SPM, i.e., particulate organic matter and mineral sediment) on marine ecosystems are typically disconnected from terrestrial studies that determine their origin, transport and fate. This study reviews sources, transport, transformations, fate and effects of SPM along the 'ridge-to-reef' continuum. We show that some of the SPM can be transported over long distances and transformed into large and easily resuspendible organic-rich sediment flocs. These flocs may lead to prolonged reductions in water clarity, impacting upon coral reef, seagrass and fish communities. Using the Great Barrier Reef (NE Australia) as a case study, we identify the latest research tools to determine thresholds of SPM exposure, allowing for an improved appreciation of marine risk. These tools are used to determine ecologically-relevant end-of-basin load targets and reliable marine water quality guidelines, thereby enabling enhanced prioritisation and management of SPM export from ridge-to-reef. PMID- 30301021 TI - Heavy metals, OCPs, PAHs, and PCDD/Fs contamination in surface sediments of a coastal lagoon (Valli di Comacchio, NW Adriatic, Italy): Long term trend (2002 2013) and effect on benthic community. AB - Surface sediments contamination (heavy metals, organochlorine pesticides, polycyclic aromatic hydrocarbons, polychlorinated dibenzodioxins and dibenzofurans) and benthic community of the Valli di Comacchio, were analysed from 2002 to 2013. Along the studied period, most of analysed pollutants did not exceed thresholds for Good chemical status of sediments. In 2008, a peak of contamination was observed, with total PAHs and OCPs exceeding their threshold. Considering metals, Ni and Cr exceeded their thresholds, but not the background levels for the area, suggesting natural enrichment; conversely Pb exceeded background levels for the area in many samples, but it exceeded its sediment quality thresholds only in few samples (2006, 2009, 2011). Conversely, the ecological status evaluated though AMBI and M-AMBI, was below the Good/Moderated thresholds established by WFD in most of the studied years. In the 11 yrs-study period, the benthic community showed a very weak response to chemical contamination.

PMID- 30301023 TI - Marine conservation in Oceania: Past, present, and future. AB - The people of Oceania have long relied on the ocean for sustenance, commerce, and cultural identity, which promulgated a sophisticated understanding of the marine environment and its conservation. Global declines in ocean health now require innovative solutions that can benefit from customary knowledge and practices, which in the past led to sustainable marine resource use. The resurgence of local stewardship, which incorporates customary practices and governance, has shown promise in many locations throughout the Pacific, although a complete return to past practices is not fully implementable owing to the loss of traditional knowledge, centralized governmental structures, economic development, and globalization. Hybrid systems that incorporate elements of customary and contemporary management can overcome some of these limitations to implementation of successful local management, and lead to greater food security, social cohesion, and the creation of an adaptive system that can potentially mitigate the effects of climate change and other stressors. PMID- 30301025 TI - Entanglement of birds in plastics and other synthetic materials. AB - Entanglement of animals is one of the main environmental impacts of waste plastic. A 2015 review of entanglement records found that the proportion of affected seabirds increased from 16% of species to 25% over the last two decades. However, this was restricted to published records; Google Images and other web based sources indicate that at least 147 seabird species (36%), as well as 69 freshwater birds (10%) and 49 landbirds (0.5%) from 53 families have been entangled in plastic or other synthetic materials. Fishing gear is responsible for entangling most species (83%), although it is often difficult to differentiate entanglement from bycatch on active gear. Mitigation measures include banning high-risk applications where there are alternatives (e.g. six pack rings), discouraging the use of high-risk items (e.g. balloons on strings, 'manja' kites), and encouraging fishers to not discard waste fishing gear by providing specific receptacles and associated educational signage in fishing areas. PMID- 30301024 TI - Performance characteristics of the temperature-modified ISO 9308-1 method for the enumeration of Escherichia coli in marine and inland bathing waters. AB - This study defines performance characteristics of the temperature-modified ISO 9308-1 method for E. coli enumeration in bathing water. After a 4-hour resuscitation period at 36 +/- 2 degrees C, the incubation temperature was changed to 44 +/- 0.5 degrees C. Elevated incubation temperature significantly suppressed the growth of thermo-intolerant bacteria, and enhanced the selectivity of Chromogenic Coliform Agar (CCA) up to 49.5% for inland and up to 66.0% for coastal water. Consequently, most of the selectivity-related performance characteristics are improved. Relative recovery was determined by comparing an alternative method against the reference, ISO 9308-1:2014 method, following the criteria set out in ISO 17994:2014. Temperature modification did not significantly alter the results and the methods were evaluated as "not different" for both, coastal and inland waters. Chromogenic Coliform Agar was assessed as a suitable medium for reliable E. coli enumeration in bathing water when incubated for 17-19 h at 44 +/- 0.5 degrees C after the 4-5 h resuscitation period at 36 +/- 2 degrees C. PMID- 30301026 TI - Variability in sediment-water carbonate chemistry and bivalve abundance after bivalve settlement in Long Island Sound, Milford, Connecticut. AB - Cues that drive bivalve settlement and abundance in sediments are not well understood, but recent reports suggest that sediment carbonate chemistry may influence bivalve abundance. In 2013, we conducted field experiments to assess the relationship between porewater sediment carbonate chemistry (pH, alkalinity (At), dissolved inorganic carbon (DIC)), grain size, and bivalve abundance throughout the July-September settlement period at two sites in Long Island Sound (LIS), CT. Two dominate bivalves species were present during the study period Mya arenaria and Nucula spp. Akaike's linear information criterion models, indicated 29% of the total community abundance was predicted by grain size, salinity, and pH. When using 2 weeks of data during the period of peak bivalve settlement, pH and phosphate concentrations accounted 44% of total bivalve community composition and 71% of Nucula spp. abundance with pH, phosphate, and silica. These results suggest that sediment carbonate chemistry may influence bivalve abundance in LIS. PMID- 30301027 TI - Do microplastics affect marine ecosystem productivity? AB - Marine and coastal ecosystems are among the largest contributors to the Earth's productivity. Experimental studies have shown negative impacts of microplastics on individual algae or zooplankton organisms. Consequently, primary and secondary productivity may be negatively affected as well. In this study we attempted to estimate the impacts on productivity at ecosystem level based on reported laboratory findings with a modelling approach, using our biogeochemical model for the North Sea (Delft3D-GEM). Although the model predicted that microplastics do not affect the total primary or secondary production of the North Sea as a whole, the spatial patterns of secondary production were altered, showing local changes of +/-10%. However, relevant field data on microplastics are scarce, and strong assumptions were required to include the plastic concentrations and their impacts under field conditions into the model. These assumptions reveal the main knowledge gaps that have to be resolved to improve the first estimate above. PMID- 30301028 TI - Historical trends of anthropogenic metals in sediments of Jiaozhou Bay over the last century. AB - Reconstructing heavy metal historical trends are essential for better understanding anthropogenic impact on marine ecosystems. In this work, the ecological risk and sources of Cr, Mn, Ni, Cu, Zn, As, Cd, and Pb in Jiaozhou Bay were studied and the anthropogenic metal emissions was also quantified. The ecological risk was mainly caused by Cd, As and Cu, which presented an increasing trend with increased anthropogenic activities since the 1950s. The statistical analysis show that Cr, Mn, Ni, Cu and Zn were primarily from natural sources. Cadmium and Mn might originate from both natural and anthropogenic sources. Arsenic and Pb were sourced from agricultural activities and atmospheric precipitation, respectively. The anthropogenic flux of Cr, Mn, Ni, Cu, Zn, As, Cd and Pb were 138, 586, 63, 66, 161, 35, 0.31 and 44 mg/m2/a since the 1950s. Over 40.0% of Cu and As were quantified from anthropogenic emissions since the 1950s. PMID- 30301029 TI - Extended-spectrum-beta-lactamase (CTX-M)-producing Escherichia coli in wild fishes from a polluted area in the Atlantic Coast of South America. AB - The presence of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli in oceanic ecosystems constitutes an emerging public health risks in the marine environment. In this study, we report for the first time the identification of ESBL (CTX-M)-producing E. coli in wild fishes from a polluted area in the South Atlantic coast of Brazil, where a genomic analysis confirm the presence of livestock and human E. coli lineages belonging to sequence types (STs) ST744 and ST746, which carried clinically relevant resistance genes for human and veterinary antibiotics, and heavy metals. These findings reveal the presence of multidrug-resistant (MDR) bacteria in the gut microbiota of wild fishes living in polluted coastal waters, alerting that microbial contamination by bacteria related directly and indirectly to human or animal activities could affect the safety of the seafood supply, as well as the commercial and recreational use of coastal marine waters. PMID- 30301030 TI - Influence of thermooxidative degradation on the in situ fate of polyethylene in temperate coastal waters. AB - Polyethylene is a commonly used polymer in plastic products and is often found as marine litter. Nevertheless there is limited knowledge about what happens to the material when it ends up in the sea. Polyethylene films were therefore thermally oxidised to four different levels of degradation. The films were then placed in stainless-steel cages in the sea off the Swedish west coast for 12 summer weeks. Subsamples were analysed with respect to biofouling, degradation and buoyancy. All levels showed a continued oxidation in the field. The pre-degraded films started fragmenting and the non-degraded films showed a decrease in tensile strain. All levels showed increased biofouling with higher presence of filamentous algae and bryozoans on pre-degraded materials. The density (kg.m-3) of the films was seen to increase slightly, and the apparent density for the pre degraded films (density of the films with biofilm) showed a strong increase, which resulted in sinking. PMID- 30301031 TI - Underwater noise levels of pile-driving in a New Zealand harbour, and the potential impacts on endangered Hector's dolphins. AB - Impact pile-driving generates loud underwater anthropogenic sounds, and is routinely conducted in harbours around the world. Surprisingly few studies of these sounds and their propagation are published in the primary literature. To partially redress this we studied pile-driving sounds in Lyttelton Harbour, New Zealand, during wharf reconstruction after earthquake damage. That Lyttelton harbour is routinely used by Hector's dolphins (Cephalorhynchus hectori), an endangered species found only in New Zealand, provided further context for this study. Steel piles of 0.61 or 0.71 m diameter were driven using three different pile-drivers. Maximum calculated source SEL was 192 dB re 1 MUPa2s @ 1 m (SPL0-p of 213 dB re 1 MUPa @ 1 m). Propagation of piling noise was strongly influenced by harbour bathymetry and a rock breakwater near the piling operation. We calculated range estimates at which Hector's dolphins may suffer temporary hearing threshold shift and behavioural change. PMID- 30301032 TI - Hydrocarbon-degradation and MOS-formation capabilities of the dominant bacteria enriched in sea surface oil slicks during the Deepwater Horizon oil spill. AB - A distinctive feature of the Deepwater Horizon (DwH) oil spill was the formation of significant quantities of marine oil snow (MOS), for which the mechanism(s) underlying its formation remain unresolved. Here, we show that Alteromonas strain TK-46(2), Pseudoalteromonas strain TK-105 and Cycloclasticus TK-8 - organisms that became enriched in sea surface oil slicks during the spill - contributed to the formation of MOS and/or dispersion of the oil. In roller-bottle incubations, Alteromonas cells and their produced EPS yielded MOS, whereas Pseudoalteromonas and Cycloclasticus did not. Interestingly, the Cycloclasticus strain was able to degrade n-alkanes concomitantly with aromatics within the complex oil mixture, which is atypical for members of this genus. Our findings, for the first time, provide direct evidence on the hydrocarbon-degrading capabilities for these bacteria enriched during the DwH spill, and that bacterial cells of certain species and their produced EPS played a direct role in MOS formation. PMID- 30301033 TI - Experimental and modeled thermoregulatory costs of repeated sublethal oil exposure in the Double-crested Cormorant, Phalacrocorax auritus. AB - To fully understand the impact of oil exposure, it is important to understand sublethal effects like how increased thermoregulatory costs may affect survival and reproduction. However, it is difficult and time-consuming to measure these effects in wild animals. We present a novel use of a bioenergetics model, Niche MapperTM, to estimate thermoregulatory impacts of oiling, using data from captive Double-crested Cormorants (Phalacrocorax auritus) experimentally exposed to oil. Oiled cormorants had significant increases in surface body temperatures following exposure. Niche Mapper accurately predicted surface temperatures and metabolic rates for unoiled and oiled cormorants and predicted 13-18% increased daily energetic demands due to increased thermoregulatory costs of oiling, consistent with increased food consumption observed in experimentally oiled cormorants. We show that Niche Mapper can provide valuable insight into sublethal oiling effects by quantifying the extent to which thermoregulatory costs divert energy resources away from important life processes like maintenance, reproduction and migration. PMID- 30301034 TI - Spreading of drill cuttings and sediment recovery of three exploration wells of different ages, SW Barents Sea, Norway. AB - Five stations (<=250 m from the well heads) from three exploration wells of different ages from the SW Barents Sea were studied to investigate the spreading of drill cuttings and sediment quality. Two of the wells were drilled before the restriction of use of oil-based drilling fluids (1993). Elevated concentrations of Ba were found in sediments near all the wells with the highest concentrations at <=60 m from the well head. The thickness of drill cutting layers was between >20 cm (well head) and 2 cm (250 m from the well head). The sediment quality varied from very bad (oldest well) to background (normal) (newer wells). Regulations led to better sediment quality. Metal concentrations from the oldest well suggested that the top 4 cm of the core represents sediment recovery. However, Ba concentrations of the top sediment layer at all the stations of the three wells indicate no physical recovery.

AB - Statistical analysis of rainfall data from 2005 to 2015 showed that atmospheric deposition supplied large amount of dissolved inorganic nitrogen (38-155 mg.m 2.month-1) in N-deficient South China Sea and Eastern Indian Ocean. To understand marine ecosystem responses to increasing nutrient disturbances, we implemented field mesocosm experiments to study phytoplankton community structure and biodiversity responses to nutrient treatments with nitrate, phosphate and iron across tropical seas. Our results showed that DIN supply would change phytoplankton community structure and stimulated the regime shift from cyanobacteria to diatoms (relative dominance R > 0). Phytoplankton communities were dominated by diatoms (relative abundance >50%) accompanied by high chlorophyll a content with 1.58-39.27 MUg.L-1 in DIN-added cultures, whereas cyanobacteria dominated communities (relative abundance >60%) with low biomass of 0.12-0.18 MUg.L-1 in undisturbed cultures. Simultaneously increased DIN loading from atmospheric deposition would decrease ecological diversity of tropical seas owing to species competition and succession (Shannon diversity H' decreased to <1).

AB - During decades, mercury (Hg) was discharged into the Aveiro Lagoon. Twenty-five years after the cessation of discharges, sediment cores were collected at two areas to assess the evolution of the mercury contamination status. Vertical Hg profiles differed considerably between bare and vegetated sediments. Bare sediments contained significantly less Hg (<8 mg kg-1) than historical data of 1995 (up to 40 mg kg-1), probably resulting from erosion. Salt marsh sediments were marked by a Hg sub-surface enrichment, reaching 44 mg kg-1 in the site closer to the industrial discharge point. High Hg concentrations in 2007, 2011 and 2016 were found at similar sediment layers. These results emphasise the role of halophyte plants in the cycling and retention of Hg in sediments. The persistency of high Hg in the upper marsh layers highlights the complexity in the recovery of historically contaminated marshes and the vulnerability to modifications in hydrology associated with climate changes.

AB - Microplastic ingestion by mesozooplankton may be an important pathway for the microplastics to enter the food web. To determine microplastic abundance in Guanabara Bay, samples were collected by neustonic haul with a 64-MUm-net and oblique hauls using 64- and 200-MUm nets. Microplastic size and abundance as well as copepod, fish-larvae, and chaetognath sizes, densities, and preferential prey sizes were determined. Microplastic abundance was higher in samples collected with fine nets (average 4.8 microplastics m-3, maximum 11 microplastics m-3) than in those collected with coarse net. Microplastic abundance in Guanabara Bay was higher than that in other marine ecosystems. Microplastics >100 MUm were too large to be ingested by copepods. However, for fish larvae and chaetognaths, the abundance of microplastics, at the corresponding prey size range, were, respectively, ~9000- and 14,400-folds lower than the preferential copepod prey, in the same size range. Thus, in Guanabara Bay, microplastics were available, but too diluted to be frequently ingested by fish larvae and chaetognaths. PMID- 30301038 TI - Testing performances of marine benthic biotic indices under the strong seasonality in the tropical intertidal habitats, South Andaman, India. AB - Understanding the natural variability and its influence on the performance of marine biotic indices used for the health assessment of marine ecosystem is the prime concern. This study addresses the seasonal variability of univariate and multimetric indices by using macrobenthic data collected from three intertidal habitats for two years (July 2013-July 2015). The univariate indices viz., abundance, richness, Shannon index and ES (100) showed strong seasonal variability. For the multimetric indices, the seasonal variability was low and appeared site specific. W-statistics, AMBI and M-AMBI showed highest constancy whilst BENTIX and BOPA exhibited wide - ranging. A general tendency could be inferred as majority of indices showed improvement in benthic quality (poor - moderate and good - high) from turbulent monsoon to stable dry period. The results are discussed concerning possible consequences especially related to the benthic community and biotic indices in intertidal habitats under the influence of sewage discharge and monsoonal effects. PMID- 30301039 TI - First report of occurrence, distribution, and composition of microplastics in surface waters of the Sea of Marmara, Turkey. AB - Plastic is produced today in large quantities and used for many purposes. At the end of use, a large part of it gets into the environment, often into the sea and there it is fragmented into the smallest fragments, so-called microplastic (MP). MPs pose a serious challenge to the marine environment such as the sources and properties of MP particles, their impact on marine organisms, and the challenges of environmental pollution. This work, carried out in the fourteen sites in the area, is the first reference to the detection of MP distribution at surface waters in the Sea of Marmara, Turkey. As a result of this study, the average level of MP in the surface was determined to be 1.263 item/m2. The results were higher compared of the most other adjacent regions and show that the Sea of Marmara started to face that problem. PMID- 30301040 TI - Assessing vessel slowdown for reducing auditory masking for marine mammals and fish of the western Canadian Arctic. AB - Vessel slowdown may be an alternative mitigation option in regions where re routing shipping corridors to avoid important marine mammal habitat is not possible. We investigated the potential relief in masking in marine mammals and fish from a 10 knot speed reduction of container and cruise ships. The mitigation effect from slower vessels was not equal between ambient sound conditions, species or vessel-type. Under quiet ambient conditions, a speed reduction from 25 to 15 knots resulted in smaller listening space reductions by 16-23%, 10-18%, 1 2%, 5-8% and 8% respectively for belugas, bowheads, bearded seals, ringed seals, and fish, depending on vessel-type. However, under noisy conditions, those savings were between 9 and 19% more, depending on the species. This was due to the differences in species' hearing sensitivities and the low ambient sound levels measured in the study region. Vessel slowdown could be an effective mitigation strategy for reducing masking. PMID- 30301041 TI - Microplastics in mussels and fish from the Northern Ionian Sea. AB - Microplastic ingestion by marine organisms presents an emerging threat to marine ecosystems; microplastics in different marine species are currently reported worldwide. This study aims to assess microplastic ingestion in four, highly commercial, marine species from Greek waters in the Northern Ionian Sea (Mediterranean Sea). Microplastics were found in mussels (Mytilus galloprovincialis) and all three fish species (Sardina pilchardus, Pagellus erythrinus, Mullus barbatus) examined. The frequency of occurrence of ingested microplastics was 46.25% in mussels, while among fish species, S. pilchardus showed the highest frequency of microplastic ingestion (47.2%). Microplastic abundance ranged from 1.7-2 items/individual in mussels and from 1.5-1.9 items/individual in fish. The majority of ingested microplastics were fragments, while their color and size varied. Fourier Transform Infrared Spectroscopy (FT IR) indicated polyethylene as the most common polymer type in mussels and fish. Results can be used to set baseline levels for the assessment of microplastic pollution in the Ionian Sea. PMID- 30301042 TI - First data on plastic ingestion by blue sharks (Prionace glauca) from the Ligurian Sea (North-Western Mediterranean Sea). AB - Few studies have focused so far on plastic ingestion by sharks in the Mediterranean Sea. The aim of this paper was to determine, for the first time, the plastic litter ingested by blue sharks (Prionace glauca), categorized as "Critically Endangered" in the Mediterranean Sea by IUCN, caught in the Pelagos Sanctuary SPAMI (North-Western Mediterranean Sea). The analysis of the stomach contents was performed following the MSFD Descriptor 10 standard protocol implemented with FT-IR spectroscopy technique. The results showed that 25.26% of sharks ingested plastic debris of wide scale of sizes from microplastics (<5 mm) to macroplastics (>25 mm). The polyethylene sheetlike user plastics, widely used as packaging material, are the most ingested debris. This research raises a warning alarm on the impact of plastic debris on a threatened species, with a key role in the food web, and adds important information for futures mitigation actions. PMID- 30301044 TI - Intensive anthropogenic activities had affected Daya Bay in South China Sea since the 1980s: Evidence from heavy metal contaminations. AB - Sediment geochemical characteristics were analyzed to assess how anthropogenic activities affected the Daya Bay, a subtropics bay adjacent to the most economically developed region of China. Vertical profiles of heavy metal contents and their enrichment factors indicated the development of Daya Bay environment in the past 100 years basically experienced three stages, which were closely consistent with the economic development. Before 1980s, the concentration of heavy metals was basically at the background level. Contamination of metals, particularly for Cr, Ni, Cu, Zn, Cd, and Pb, generally began in mid-1980s and became serious in 2000s. However, after late-2000s, the sediment quality had been radically improved. Heavy metals in nearshore sediment of Daya Bay were all closely related with import of anthropogenic and/or terrestrial material, whereas those in offshore were likely to be related with joint influence from the anthropogenic activities and the natural processes. PMID- 30301043 TI - Proteome responses of Gracilaria lemaneiformis exposed to lead stress. AB - Proteome response of plants is an important process that enables them to cope with environmental stress including metal stress. In this study, the proteome of Gracilaria lemaneiformis exposed to lead was investigated. Two-dimensional gel electrophoresis analysis revealed 123 protein spots, among which 14 proteins were significantly differentially expressed and identified using MALDI-TOF MS. Two of the up-regulated proteins were identified and predicted to be involved in photosynthesis and signal transduction, while eleven down-regulated proteins were functionally grouped into five classes including photosynthesis, energy metabolism, protein metabolism, carbohydrate transport and metabolism, and antioxidation proteins. There was also an up-regulation in superoxide dismutase, peroxidase, glutathione s-transferase, and heat-shock protein 70 upon Pb exposure. Proteomic studies provide a better picture of protein networks and metabolic pathways primarily involved in intracellular detoxification and defense mechanisms. PMID- 30301045 TI - Contributions of pre- versus post-settlement processes to fluctuating abundance of crown-of-thorns starfishes (Acanthaster spp.). AB - Numerous hypotheses have been put forward to account for population outbreaks of crown-of-thorns starfishes (CoTS, Acanthaster spp.), which place specific importance on either pre- or post-settlement mechanisms. The purpose of this review is to specifically assess the contributions of pre- versus post-settlement processes in the population dynamics of CoTS. Given the immense reproductive potential of CoTS (>100 million eggs per female), persistent high densities would appear inevitable unless there were significant constraints on larval development, settlement success, and/or early post-settlement growth and survival. In terms of population constraints, pre- and post-settlement processes are both important and have additive effects to suppress densities of juvenile and adult CoTS within reef ecosystems. It is difficult, however, to assess the relative contributions of pre- versus post-settlement processes to population outbreaks, especially given limited data on settlement rates, as well as early post-settlement growth and mortality. Prioritising this research is important to resolve potential effects of anthropogenic activities (e.g., fishing) and habitat degradation on changing population dynamics of CoTS, and will also improve management effectiveness. PMID- 30301046 TI - A critical review of marine snow in the context of oil spills and oil spill dispersant treatment with focus on the Deepwater Horizon oil spill. AB - Natural marine snow (NMS) is defined as the "shower" of particle aggregates formed by processes that occur in the world's oceans, consisting of macroscopic aggregates of detritus, living organisms and inorganic matter. Recent studies from the Deepwater Horizon oil spill suggest that marine snow is also formed in association with oil spills and was an important factor for the transport of oil to the seabed. This review summarizes the research and literature on MS, mainly from the DWH oil spill, with a focus on the relation between the use of oil spill dispersants and the formation and fate of oil-related marine snow (ORMS). Studies are still required to determine ORMS processes at oil concentrations as relevant as possible for chemically dispersed oil. PMID- 30301047 TI - Sustainable recycling of mooring ropes from decommissioned offshore platforms. AB - Decommissioning offshore Floating Production, Storage and Offloading (FPSO) platforms requires extensive technical knowledge, since it generates different post-consumer materials, including mooring lines. These ropes are made from polyester high tenacity yarn, based on polyethylene terephthalate (PET), and their high added value means they should not be discarded as scrap. This paper aims to present a review and technical opportunities, from an economic standpoint, of recycling the mooring lines recovered from decommissioned FPSOs. Studies conducted over the last two years have researched and developed different potential applications for the fibers. These studies include collaborative project initiatives involving technical and management professionals, universities and private enterprises, with a view to achieving a more sustainable destination for these fibers. PMID- 30301048 TI - 20th century increase in body size of a hypoxia-tolerant bivalve documented by sediment cores from the northern Adriatic Sea (Gulf of Trieste). AB - An increase in the frequency of hypoxia, mucilages, and sediment pollution occurred in the 20th century in the Adriatic Sea. To assess the effects of these impacts on bivalves, we evaluate temporal changes in size structure of the opportunistic bivalve Corbula gibba in four sediment cores that cover the past ~500 years in the northern, eutrophic part and ~10,000 years in the southern, mesotrophic part of the Gulf of Trieste. Assemblages exhibit a stable size structure during the highstand phase but shift to bimodal distributions and show a significant increase in the 95th percentile size during the 20th century. This increase in size by 2-3 mm is larger than the northward size increase associated with the transition from mesotrophic to eutrophic habitats. It coincides with increasing concentrations of total organic carbon and nitrogen, and can be related to enhanced food supply and by the tolerance of C. gibba to hypoxia. PMID- 30301049 TI - Plastic litter transfer from sediments towards marine trophic webs: A case study on holothurians. AB - This study estimates for the very first time plastic litter levels in sea cucumbers (Echinodermata, Holothuroidea) sampled in situ and their intakes from sediments in three different rocky bottom habitats (slides, cliff, banks) settled in Salina Island (Aeolian Archipelago). Macroplastic were never recorded while meso- and microplastics were identified in all sediment (81-438 items/kg d.w.) and animal samples (1.8-22 items/ind.). Plastic intakes by sea cucumbers resulted frequently associated to the size range included within 100-2000 MUm. Over than 70% of ingested plastic litter is represented by the size fraction >500 MUm. Sediment/animals ratios % are included 2.7 +/- 2.0% in studied habitats with a selective intake of fragments occurring in slides. Furthermore, results support the occurrence of selective ingestion of plastic litter by holothurians in natural environments underlining the role of these species in microplastic transfer from abiotic towards biotic compartments of the marine trophic web. PMID- 30301050 TI - Using a genetic algorithm to improve oil spill prediction. AB - The performance of oil spill models is strongly influenced by multiple parameters. In this study, we explored the ability of a genetic algorithm (GA) to determine optimal parameters without the need for time-consuming manual attempts. An evaluation function integrating the percentage of coincidence between the predicted polluted area and the observed spill area was proposed for measuring the performance of a Lagrangian oil particle model. To maximise the objective function, the oil spill was run numerous times with continuously optimised parameters. After many generations, the GA effectively reduced discrepancies between model results and observations of a real oil spill. Subsequent validation indicated that the oil spill model predicted oil slick patterns with reasonable accuracy when equipped with optimal parameters. Furthermore, multiple objective optimisation for observations at different times contributed to better model performance. PMID- 30301051 TI - Development of analytical methods used for the study of 2,4,6-trinitrotoluene degradation kinetics in simulated sediment samples from the Baltic Sea. AB - Large amounts of ammunition containing 2,4,6-trinitrotoluene (TNT) and other substances were dumped in the Baltic Sea after WWII. Considering progressive corrosion processes, studying the transformation of TNT occurring in the environment constitutes an important aspect of a possible associated risk. This study focused on the transformations of TNT in simulated conditions of the Baltic Sea bottom sediment. Methods of analysis of TNT and selected products of its transformations were developed for that purpose. The developed methods allowed for the determination of selected compounds below 1 ng/g. Systematic monitoring of TNT transformations in the environment of the bottom sediment was performed. This allowed for the determination of the kinetics of TNT degradation and identification of degradation reaction products. Based on the obtained results, the TNT decay half-time in conditions present in the Baltic Sea was estimated to be 16.7 years for the abiotic environment and 5.6 for the biotic environment. PMID- 30301052 TI - Microtidal estuaries warrant special management measures that recognise their critical vulnerability to pollution and climate change. AB - Not all estuaries are equally susceptible to anthropogenic perturbation. Microtidal estuaries with long residence times are intrinsically less robust than well-flushed macrotidal estuaries, facilitating the accumulation of contaminants. This promotes development of blooms of non-toxic and toxic phytoplankton, and hypoxia and anoxia may occur in deeper sections of the typically stratified water column. In Mediterranean and arid climates, high temperatures and low and/or seasonal rainfall can result in marked hypersalinity. Thus, any increase in anthropogenic perturbation will further decrease the health of a system in which the biota already experiences natural stress. Microtidal estuaries are also more susceptible to climate change, the detrimental longer-term effects of which are becoming manifestly obvious. Numerous attempts have been made to develop novel solutions to problems caused by eutrophication, phytoplankton blooms, hypoxia and hypersalinity, which have met with various levels of success, but the need for such measures and effective legislation is increasingly critical. PMID- 30301053 TI - Towards cleaner shores: Assessing the Great Canadian Shoreline Cleanup's most recent data on volunteer engagement and litter removal along the coast of British Columbia, Canada. AB - This paper analyzes voluntary cleanups organized by the Great Canadian Shoreline Cleanup (GCSC) along the coast of British Columbia (2013-2016). Cleanup performance indicators, litter composition and diversity were compared between years and across areas (i.e., North Coast of British Columbia, Inner Coast of Vancouver Island, West Coast of Vancouver Island, and Southern Strait of Georgia). Significant differences in parameters were found between areas but not across time. Spatial variation in trash composition and diversity was mostly related to source of litter. Trash yield per kilometre of shoreline was higher in isolated areas and in areas with exposed shorelines. The majority of recovered litter items were composed of plastic. Local actions, complementary to the GCSC, such as banning single-use, non-biodegradable takeout containers on beaches, implementing trash buyback programs, and modifying waste management and recycling regulations, are proposed as mechanisms for strengthening the prevention and mitigation of coastal pollution in British Columbia. PMID- 30301054 TI - An alternative approach to bioaccumulation assessment of methyl-Hg, total-Hg, Cd, Pb, Zn in bivalve Anomalocardia brasiliana from Rio de Janeiro bays. AB - We present an alternative approach for establishing in situ bioaccumulation assessment of methyl-Hg (MeHg), total-Hg, Cd, Pb and Zn in bivalve Anomalocardia brasiliana from four bays of Rio de Janeiro presenting varying degrees of eutrophication, acid volatile sulfides (2-55 MUmol g-1), simultaneously extracted metals (SEM) and total metals (TM) in sediments. Using metal concentrations of composite samples from three size classes of bivalve and their incorporation rates (IR = metal concentration / total length), which depend on exposure time, we calculated asymptotic IR and respective consequent metal concentrations. Both IR and the metal concentration presented inverse relationships with total length (excepting MeHg) and bay contamination. Lead and zinc concentrations were above Brazilian legal criteria in the most anoxic and contaminated bay, suggesting significant metal bioavailability (SEM/TM between 8% and 63%). PMID- 30301055 TI - Degradation of petroleum hydrocarbons in seawater by simulated surface-level atmospheric ozone: Reaction kinetics and effect of oil dispersant. AB - Oil degradation by surface-level atmospheric ozone has been largely ignored in the field. To address this knowledge gap, this study investigated the ozonation rate and extent of typical petroleum compounds by simulated surface-level ozone, including total petroleum hydrocarbons (TPHs), n-alkanes, and polycyclic aromatic hydrocarbons (PAHs). Moreover, the work explored the effect of a prototype oil dispersant, Corexit EC9500A, on the ozonation rate. Rapid oxidation of TPHs, n alkanes and PAHs was observed at various gaseous ozone concentrations (i.e. 86, 200 and 300 ppbv). Generally, the presence of the oil dispersant enhanced ozonation of the oil compounds. The addition of humic acid inhibited the reaction, while increasing salinity accelerated the degradation. Both direct ozonation by molecular ozone and indirect oxidation by ozone-induced radicals play important roles in the degradation process. The findings indicate that ozonation should be taken into account in assessing environmental fate and weathering of spilled oil. PMID- 30301056 TI - Determination of radiological hazard parameters in sea snails (Rapana venosa) in the East Black Sea Coast of Turkey. AB - The aim of this study was to determine the activity concentrations and radiological hazard parameters of 137Cs and 40K in soft tissue samples of sea snails (Rapana venosa) collected from 12 different stations in the East Black Sea coastal area of Turkey. The values in soft tissues of sea snail samples with three different sizes were between 0.31 and 1.79 Bq kg-1 for 137Cs and 163.9 and 269.4 Bq kg-1 for 40K. The mean activity concentrations of 137Cs and 40K in tissues of small-sized sea snails were determined to be higher than those of 137Cs and 40K in soft tissues of the other sizes. The determined activity concentration values were lower than the concentrations reported in similar studies. Radiological hazard parameters such as the daily intake (Dint) of 137Cs and 40K, annual committed effective dose (Eeff), and lifetime cancer risk (LCR) were calculated and compared with the international recommended values. PMID- 30301057 TI - Natural radioactivity in the beach sand and soil along the coastline of Guangxi Province, China. AB - Natural radioactivity in the beach sand and soil was measured and evaluated in typical ecosystems of mangroves, seagrasses, and coral reefs along the coastline of Guangxi Province, China. Radioactivity in the soil was about three times higher than that in the beach sand probably due to the distinct mineral components and particle sizes. A comparison with natural radioactivity levels in the global beach sands indicated that the beach sand of Guangxi had the lowest radioactivity. Radiological parameters including radium equivalent activity (Raeq), external and internal hazard indices (Hex and Hin), representative gamma level index (Igammar), absorbed gamma dose rate (DR), and annual effective dose equivalent (AEDE) were lower than the recommended values. Our results provide baseline data on radioactivity in the beach sand and soil along the coastline of Guangxi and contribute to the database of radioactivity in the global beach sand. PMID- 30301058 TI - Microplastics analysis in Malaysian marine waters: A field study of Kuala Nerus and Kuantan. AB - The first report on the emergence of microplastic in Malaysian marine waters was documented in this study. Water samples were collected from two regions, namely Kuala Nerus and Kuantan port, as the representatives of different anthropogenic activities. Identification of microplastic was performed based on physical characteristics (colour, shape, density) and chemical characterisation (ATR-FTIR analysis) for a functional group of polymers. Fragment type, black or grey colour and high density (>1.02 g cm-3) of microplastic were the most prevalent characteristics found in both areas. Two principal components (density and colour) rendered explained about 95.3% (Kuantan) and 95.6% (Kuala Nerus) of the total variance. Six possible polymer materials were identified, namely polyester, polystyrene, polyamide, polyvinyl chloride, polypropylene, and polyethylene. The findings of the study provided good baseline information on marine debris issue in Malaysia. PMID- 30301059 TI - Using citizen science data to assess the difference in marine debris loads on reefs in Queensland, Australia. AB - The prevalence of marine debris in global oceans is negatively impacting the marine environment. In Australia, marine debris has been an increasing concern for sensitive marine environments, such as coral reefs. Citizen science can contribute data to explore patterns of subtidal marine debris loads. This study uses data from Reef Check Australia to describe patterns of debris abundance on reef tourism sites in two Queensland regions, the Great Barrier Reef (GBR) and Southeast Queensland (SEQ). Debris was categorized into three groups, fishing line, fishing net, and general rubbish. Overall, debris abundance across reefs was relatively low (average 0.5-3.3 items per survey (400 m2)), but not absent on remote reefs surveyed in the GBR region. Highest debris loads were recorded in SEQ near cities and high use areas. These results indicate the presence of marine debris on remote and urban reefs, and the applicability of using citizen science to monitor debris abundance. PMID- 30301060 TI - Photoacclimation to light-limitation in a clionaid sponge; implications for understanding sponge bioerosion on turbid reefs. AB - Watershed-based pollution is a common form of coral reef degradation. Affected reefs are often highly turbid, where light-limitation confines the distribution of photosynthetic benthic taxa and the capacity for photoacclimation is important for survival. We investigated low light photoacclimation in a Symbiodinium hosting bioeroding sponge using in situ PAM fluorometry. Cliona aff. viridis was artificially shaded (70 & 95% ambient light reduction) on a low turbidity Indonesian reef for 25 days, with a subsequent 14-day recovery period. Significant changes in rETRmax, and qP, and a non-significant but observable decline in Ek, demonstrated that C. aff. viridis is able to photoacclimate to conditions of extreme light reduction and recover within a relatively short period of time. The sponge is therefore unlikely to be light limited on even the most turbid reefs. However, other aspects of watershed-pollution such as sedimentation may still limit their distribution in affected coastal waters. PMID- 30301061 TI - An 87-year sedimentary record of mercury contamination in the Old Yellow River Estuary of China. AB - A sediment core, spanning from the year 1925 +/- 3.03 to 2012, was collected for analyzing historical distribution of mercury (Hg) in the Old Yellow River Estuary (OYRE), China. The Hg concentrations in the sediment core ranged from 14 to 351 ng g-1, with the high values occurred in the middle layers (1960-1996), which may be resulted from intensive human activities during this period, such as oil exploitation and booming of petrochemical industry, salt chemical industry and chlor-alkali plants. A significant positive correlation was found between THg and loss on ignition (LOI). The main fraction of Hg existed in residual part while the fraction that was easy to leach out from sediments accounted for only a small portion according to the results of BCR sequential extraction procedure. Multiple ecological risks indices and guidelines of Hg indicated that the sedimentary record presented an "intermediate state" for Hg contamination in the OYRE. PMID- 30301063 TI - Quantification of microfibre levels in South Africa's beach sediments, and evaluation of spatial and temporal variability from 2016 to 2017. AB - The microfibre content of beach sediment samples was established at 175 sampling sites along over 2700 km of South Africa's coastline in 2016 and again in 2017. The average microfibre content was 80 +/- 102 F/dm3 in Feb/March 2017 (n = 161), and 87 +/- 84 F/dm3 in May/June 2016 (n = 128). These average values, and the observed ranges of 0 to 797 F/dm3 in 2017 and 4 to 772 F/dm3 in 2016, are consistent with global observations. The highest microfibre levels were observed at sampling sites close to large coastal waste water treatment work discharge points. Several instances of temporal variability are observed, only some of which can be associated with seasonal changes in river runoff. This baseline data set is a valuable reference point for identification of priority study sites for more detailed study of marine ecosystem response to microfibre pollution. PMID- 30301062 TI - Microbial water quality and the detection of multidrug resistant E. coli and antibiotic resistance genes in aquaculture sites of Singapore. AB - Poor microbial water quality jeopardizes the health and safety of food produced by aquaculture farms. Three fish farms and transect sites in Singapore were assessed for microbial water quality and antimicrobial resistance determinants. Of the 33 multidrug resistant E. coli isolated from surface waters of the Johor Straits, 81.8% were ESBL producers. The relative abundance of sul1, qnrA and intI1 genes were higher in sediments than surface waters. Among the surface water samples, higher concentrations (10-1-101) of beta-lactamases (blaSHV, blaOXA, blaCTX-M) were detected in the transect sites. This study highlights a potential antimicrobial resistance transmission chain from environmental waters, to animal carriers and humans. PMID- 30301064 TI - An environmental risk assessment of three organic UV-filters at Lac Bay, Bonaire, Southern Caribbean. AB - Although organic UV filters (OUVFs) benefit human health by preventing skin burns and cancer, several studies revealed that organic UV filters can induce developmental and reproductive toxicity to aquatic organisms. Discharge of OUVFs occurs predominantly at marine recreational hotspots, such as Lac Bay, Bonaire, and is predicted to increase significantly due to growing tourism worldwide. Unfortunately, there is no insight what the current and future discharge of OUVF at Lac Bay is. Therefore, this study aimed to 1) measure concentrations and estimate the risk of specific OUVFs to different nursery habitats at Lac Bay, and 2) compare measured and predicted concentration based risk assessment outcome. Results showed that at least one of the three nurseries at Lac Bay had a potential for adverse effects. Furthermore, predicted environmental concentrations of UV filter discharge can be applied to gain more insight in the order of extent of OUVF discharge by marine tourism. PMID- 30301065 TI - Impact of anthropogenic activities on mussel (Mytella guyanensis) in the Gulf of Paria, Trinidad. AB - This body of work demonstrated the levels of selected contaminants (as well as their potential sources), in mussels (Mytella guyanensis) - a known bio-indicator of pollution, along the west coast (Gulf-of-Paria) of Trinidad. The findings demonstrated that polyaromatic hydrocarbons levels in the mussels investigated were moderate to high (201.80-1200.08 MUg/kg). Notably, benzo(a)pyrene levels (1.15-9.32 MUg/kg) exceeded the European Union guidelines at various sites. The distribution of PAHs and trace elements in the Gulf of Paria are impacted by tidal currents and local source discharge. Significant risks were identified from toxic carcinogenic equivalent levels (3.01 to 22.37 MUg/kg) and mutagenic equivalent levels (3.98 to 38.61 MUg/kg). The concentration of trace elements, Zn (46.05-56.36 mg/kg) and Cd (0.46-1.17 mg/kg), exceeded both local and international guidelines at certain sites investigated. The analysis revealed a high bioavailability of the identified pollutants in the Gulf of Paria from industrial, urban and marine activities. PMID- 30301066 TI - Sources and fate of organic matter in constructed versus natural coastal waterways. AB - Coastal wetlands are increasingly being converted into canal estates with potential consequences for ecosystem functioning. We compared the sources and fate of organic matter and water quality at four types of canal habitats (entrances and ends of canals, canal lakes and lake edges) and shallow and deep natural habitats (four replicates of each habitat). The fate of labile organic matter was assessed by measuring rates of scavenging of carrion. Surface sediments were analysed for organic carbon content and stable carbon isotopes, fatty acid biomarkers and compound specific stable isotope analysis of selected fatty acids were used to elucidate sources of sedimentary organic matter. Canal lakes differed from other habitats and were characterised by negligible scavenging, larger quantities of organic matter comprised of higher contributions from diatoms, and hypoxia. Despite some trends, natural habitats were statistically indistinguishable from canal entrances and ends. Variation among replicate habitats was large. PMID- 30301067 TI - Whole genome sequences to assess the link between antibiotic and metal resistance in three coastal marine bacteria isolated from the mummichog gastrointestinal tract. AB - Antibiotic resistance is a global public health issue and metal exposure can co select for antibiotic resistance. We examined genome sequences of three multi drug and metal resistant bacteria: one Shewanella sp., and two Vibrio spp., isolated from the gut of the mummichog fish (Fundulus heteroclitus). Our primary goal was to understand the mechanisms of co-selection. Phenotypically, the strains showed elevated resistance to arsenate, mercury, and various types of beta-lactams. The genomes contained genes of public health concern including one carbapenemase (blaOXA-48). Our analyses indicate that the co-selection phenotype is mediated by chromosomal resistance genes and cross-resistance. No evidence of co-resistance was found; most resistance genes were chromosomally located. Moreover, the identification of many efflux pump gene homologs indicates that cross-resistance and/or co-regulation may further contribute to resistance. We suggest that the mummichog gut microbiota may be a source of clinically relevant antibiotic resistance genes.

AB - The United Arab Emirates fisheries consist of highly diverse fish communities, and the most popular equipment used by fishermen to harvest them is a traditional baited basket fishing trap known locally as "gargoor". Gargoors are dome-shaped traps made from galvanized steel; they have a circular supporting base and a funnel-like entrance. Unintended impacts of gargoors on marine fauna include bycatch of non-target species and, when lost, ghost fishing. However, there is very little information on sea turtle interaction with gargoors. In this paper we present two case reports from the eastern coast of the UAE of green sea turtle strandings associated with gargoor interactions. The first case report describes a turtle that was discovered trapped inside a lost or abandoned gargoor. The second case report describes another turtle that suffered from extensive perforation of the gastrointestinal tract resulting from the ingestion of 32 pieces of rusty gargoor fragments.

Ballast water, used to provide vessel stability, has been associated with the introduction of marine invasive species. Thus, understanding ballasting trends is imperative to protecting human and environmental health. This paper examines data from the National Ballast Information Clearinghouse to assess ballasting behavior and shipping trends in the United States. From 2005 to 2017, vessel arrivals have remained relatively constant (annual growth rate of 1.2% per year) while total ballast discharge per vessel has grown at an annual rate of 7.6%. Furthermore, from 2014 to 2016, alternative ballast water management methods have been on the rise, and these treatment options are likely to continue increasing in response to the International Maritime Organization Ballast Water Management Convention that entered into force in September 2017. It is critical that the shipping industry monitors potential cascading impacts on other ballasting behaviors stemming from this shift. PMID- 30301070 TI - The impact of ghost fishing on catch rate and composition in the southern Caspian Sea. AB - The catch rates and the catch composition of lost nets were investigated during two seasons (fall and winter) in the southern Caspian Sea. A total of 167 surveys were conducted using anchor to retrieve ghost nets, which led to recover a total of 515 monofilaments gillnet. The most abundant caught species in during both seasons was belonged to Alosa caspia (52.1-43.9%). At both seasons, individuals of Huso huso, and Acipenser stellatus were substantially caught below the length at first maturity. The highest mean of catch rates was discovered at 0-10 m depth (2.79 kg), while the depth of 10-20 m provided the lowest amount of catch (2.0 kg). The Spearman correlation test showed that an increase in depth is reflected in lower values of the retrieved ghost nets. Overall, this study revealed that ghost gillnets is widely distributed in the southern Caspian Sea, mainly at the shallow waters.

AB - Based on a survey conducted from June to July 2013, aragonite saturation state variation and control in the river-dominated marginal BoHai and Yellow seas were investigated. Surface water Omegaarag ranged from 2.0-3.8, whereas subsurface water Omegaarag was generally lower than 2.0. Temperature changes had a strong influence on Omegaarag through induced CO2 solubility changes in seawater. Riverine freshwater input decreased Omegaarag in the Changjiang and Yalu river estuaries, but induced higher Omegaarag in the Yellow River estuary. Biological processes had opposite effects on Omegaarag, whereby elevated biological production led to the highest Omegaarag in the South Yellow Sea surface water, whereas net community respiration/remineralization induced low Omegaarag in subsurface water. Stratification affected the level and scale of low Omegaarag in subsurface water. By the year 2100, surface water with Omegaarag > 2.0 will disappear except for the Yellow River estuary, and most of the subsurface water will develop substantial aragonite undersaturation. PMID- 30301072 TI - Marine debris ingestion of green sea turtles, Chelonia mydas, (Linnaeus, 1758) from the eastern coast of the United Arab Emirates. AB - The deleterious effects of marine debris ingestion on marine turtles are well documented in literature globally. In this study, the qualitative and quantitative aspects of marine debris ingested by 14 stranded green sea turtles Chelonia mydas, (Linnaeus, 1758) along the eastern coast of the United Arab Emirates were investigated. The numeric and gravimetric proportions of debris in the esophagus, stomach and intestines were documented following classification of color, presumed sources and Marine Strategy Framework Directive categories and sub-categories. The results show that 85.7% of the specimens examined consumed marine debris. On average, specimens consumed 61.9 +/- 17.2 items of 1.0 +/- 0.3 g mass. Plastics, particularly white, and transparent thread-like and sheet-like plastics, were the predominant debris ingested. The results reflect a potentially high level of interaction between green sea turtles and anthropogenic marine debris along the Gulf of Oman coast of the UAE. PMID- 30301073 TI - Marginal coral reefs show high susceptibility to phase shift. AB - Phase shift, resulting from coral reef degradation, has been frequently recorded on reefs in optimal conditions, while marginal reefs were considered more resistant due to few records. Noting the lack of marginal reef phase shift studies, we quantitatively assessed their geographic extent in the Southwest Atlantic. Using metadata and a calculated phase shift index, we identified phase shifts from corals to both zoanthid and macroalgal dominance. Positive correlations existed between phase shift and local human impacts for zoanthids: proximity to human populations >100,000 inhabitants, urbanized surfaces and dredged ports and a negative relationship to the endurance of SST >1 degrees C above normal. Macroalgal shifts positively correlated to ports and urbanized surfaces, higher latitudes and shore proximity, indicating a possible link to nutrient runoff. The high frequency of these phase shifts suggests greater degradation than reported for Caribbean reefs, suggesting that marginal reefs do not have higher natural resistance to human impacts. PMID- 30301074 TI - Characteristics of phytoplankton assemblages in the southern Yellow Sea, China. AB - The characteristics of phytoplankton assemblages were analyzed by the Utermohl method in the southern Yellow Sea in summer, 2008. A total of 113 species (including varieties and forms), belonging to 51 genera and 3 phyla, were identified. Diatom was the most dominant group. The dominant species included Eucampia zoodiacus, Leptocylindrus danicus, Chaetoceros affinis, Thalassionema nitzschioides, Skeletonema costatum, Paralia sulcata and Chaetoceros tortissimus, which were eurytopic and temperate species. The cell abundance of phytoplankton ranged from 0.04 to 620.08 cells.mL-1 with an average of 27.52 cells.mL-1. Horizontally, the cell abundance showed a decreasing trend from the south to the north. In terms of vertical distribution, the values in surface and subsurface water layers were higher than those in bottom water layers. Results of correlation analysis showed that phytoplankton cell abundance was positively correlated with water temperature, ammonia and nitrite concentrations, and negatively correlated with salinity and silicate concentration. PMID- 30301075 TI - On the transport and modeling of dispersed oil under ice. AB - Theoretical arguments and numerical investigations were conducted to understand the transport of oil droplets under ice. It was found that the boundary layer (BL) in the water under ice produces a downward velocity that reaches up to 0.2% of horizontal current speed, and is, in general, larger than the rise velocity of 70 MUm oil droplets. The eddy diffusivity was found to increase with depth and to decrease gradually afterward. Neglecting the gradient of eddy diffusivity when conducting Lagrangian transport of oil droplets would result in an unphysical spatial distribution. When the downward velocity of water was neglected, oil accumulated at the water-ice interface regardless of the attachment efficiency. The lift force was found to scrape off droplets of the ice, especially for droplets <= 70 MUm. These findings suggest that previous oil spill simulations may have overestimated the number of small droplets (<=70 MUm) at the water-ice interface. PMID- 30301076 TI - Sorption behaviors of tris-(2,3-dibromopropyl) isocyanurate and hexabromocyclododecanes on polypropylene microplastics. AB - In recent years, microplastics in oceans have become a serious environmental problem and the focus of attention. In the present study, the sorption of TBC and HBCDs by microplastics in simulated seawater is examined. The effects of particle size, temperature, salinity, and concentration on the adsorption of TBC and HBCDs by microplastics are studied. Results indicate that the first-order adsorption kinetic model is more suitable than the pseudo-second-order kinetic model to describe adsorption. The equilibrium adsorption times are 15 h and 10 h for TBC and HBCDs, respectively. The adsorption capacity increases with the decrease in particle size. The adsorption capacity gradually increases at first and then decreases with the increase in salinity and temperature. The maximum adsorption capacity is at 15 degrees C and 14% salinity. Compared with the linear and Freundlich models, the Langmuir model is more suitable; this indicates that the main adsorption mechanism might be chemical adsorption. PMID- 30301077 TI - Scleractinian coral microplastic ingestion: Potential calcification effects, size limits, and retention. AB - The impact that microplastics (<5 mm) have on scleractinian coral is largely unknown. This study investigated calcification effects, size limits, and retention times of microbeads and microfibers in two Caribbean species, Montastraea cavernosa and Orbicella faveolata, in a series of three experiments. No calcification effects were seen in the two-day exposure to a microbead concentration of 30 mg L-1. M. cavernosa and O. faveolata actively ingested microbeads ranging in size from 425 MUm-2.8 mm, however, a 212-250 MUm size class did not elicit a feeding response. The majority of microbeads were expelled within 48 h of ingestion. There was no difference in ingestion or retention times of 425-500 MUm microbeads versus 3-5 mm long microfibers. M. cavernosa and O. faveolata have the ability to recognize and reject indigestible material, yet, there is still a need to study effects of energetics and microplastic contamination as a result of ingestion and egestion. PMID- 30301078 TI - Highly polluted life history and acute heat stress, a hazardous mix for blue mussels. AB - Intertidal sessile organisms constitute through their life history unintended stress recorders. This study focuses on the impact of pollution on Mytilus edulis ability to cope with an additional stress. For this purpose, two acclimation stages to different temperatures were conducted before an acute stress exposure in mussels collected from a heavily polluted site. Gill proteomes were analyzed by 2DE and regulated proteins identified. Massive mortality was observed for organisms acclimated to colder temperatures. Despite this major difference, both groups shared a common response with a strong representation of proteoforms corresponding to "folding, sorting and degradation" processes. Nevertheless, surviving mussels exhibit a marked increase in protein degradation consistent with the observed decrease of cell defense proteins. Mussels acclimated to warmer temperature response is essentially characterized by an improved heat shock response. These results show the differential ability of mussels to face both pollution and acute heat stress, particularly for low-acclimated organisms. PMID- 30301079 TI - Sources and trends of artificial sweeteners in coastal waters in the bay of Cadiz (NE Atlantic). AB - This is the first comprehensive study on the input, occurrence, and distribution of artificial sweeteners (ASs) in coastal wastewater treatment plants (WWTPs) and their receiving coastal waters. Acesulfame (ACE), aspartame (ASP), cyclamate (CYC), saccharine (SAC), and sucralose (SUC) were monitored for 6 months in Cadiz Bay (SW Spain). ASP was always detected at <0.1 MUg L-1 and removal efficiencies were >90% for SAC and CYC. Higher ACE removal efficiencies were observed during warmer months. Persistence of ACE and SUC was observed in both WWTPs and their receiving coastal surface waters, where values up to 0.6 and 3 MUg L-1 were measured, respectively. The highest concentrations were measured in a sewage impacted estuary located in the north of the bay, where conservative behavior was confirmed. The source specificity and recalcitrance of ACE and SUC make them suitable for being used as sewage-pollution markers in coastal environments. PMID- 30301080 TI - Carbon economy of Mediterranean seagrasses in response to thermal stress. AB - Increased plant mortality in temperate seagrass populations has been recently observed after summer heatwaves, although the underlying causes of plant death are yet unknown. The potential energetic constrains resulting from anomalous thermal events could be the reason that triggered seagrass mortality, as demonstrated for benthic invertebrates. To test this hypothesis, the carbon balance of Posidonia oceanica and Cymodocea nodosa plants from contrasting thermal environments was investigated during a simulated heatwave, by analyzing their photosynthetic performance, carbon balance (ratio photosynthesis:respiration), carbohydrates content, growth and mortality. Both species were able to overcome and recover from the thermal stress produced by the six-week exposure to temperatures 4 degrees C above mean summer levels, albeit plants from cold waters were more sensitive to warming than plants from warm waters as reflected by their inability to maintain their P:R ratio unaltered. The strategies through which plants tend to preserve their energetic status varied depending on the biology of the species and the thermal origin of plants. These included respiratory homeostasis (P. oceanica warm-plants), carbon diversion from growth to respiration (C. nodosa cold-plants) or storage (P. oceanica warm plants) and changes in biomass allocation (C. nodosa warm-plants). Findings suggest an important geographic heterogeneity in the overall response of Mediterranean seagrasses to warming with potential negative impacts on the functions and services offered by seagrass meadows including among others their capacity for carbon sequestration and carbon export to adjacent ecosystems. PMID- 30301081 TI - Litter & microplastics features in table salts from marine origin: Italian versus Croatian brands. AB - This study estimates litter content, including microplastics, mesoplastic, and macroplastic in marine table salts coming from Italy and Croatia. Both high (HC) and low (LC) costs commercial brands easily found at the supermarket were analysed. Any macroplastic or mesoplastic were recovered while microplastics and other litter impurities significantly affect table salts of all tested brands. Average microplastic values ranged within 1.57 (HC) - 8.23 (LC) (Italy) and 27.13 (HC) - 31.68 (LC) items/g (Croatia). Microplastics sizes (min-max) ranged within 4-2100 MUm (Italy) and 15-4628 MUm (Croatia). In samples from both Nations, a significant general positive correlation between the average number of items/g recorded and the total amount of general impurities was recorded. Concerning microplastic shapes, in Italy, fragments dominated even if fibres, granules, films, and foams are frequently recorded. On the contrary, clear PP fibres dominated in Croatian brands even if also other shape classes were recorded. PMID- 30301082 TI - The effects of plastic bags presence on a macrobenthic community in a polluted estuary. AB - The damaging effects of marine debris on wildlife are often noted through the observation of animals that ingest and/or become entangled in debris. Yet, few studies have evaluated the effects of marine litter on benthic habitats. The aim of this study was to investigate if the presence of plastic bags has any effect on benthic macrofauna in an estuary located in an urban area in North-eastern Brazil. Biogeochemical and macrofauna samples were obtained from 10 different deposition locations (location factor), under, border and distant (treatment factor) from plastic bags. The results did not show any significant alterations in the biogeochemical parameters of the sediment due to treatment effect except for summed microphytobenthic pigments. The macrobenthic community structure responded to treatment. The greatest dissimilarity (34%) was between samples that were under and distant. Effects occurred despite the high dynamics of deposition resuspension of plastic bags and the dominance of opportunistic species. Changes in community structure are a complex result of plastic bags effects on species ecological interactions in the polluted estuarine environment, attracting deposit feeders, diminishing suspension feeders and providing mechanical protection against predation by seabirds. PMID- 30301084 TI - Sex may influence environmental diphenhydramine accumulation in Round Stingrays. AB - Despite the amount of treated wastewater discharged into the Southern California Bight, few studies have examined pharmaceutical compounds in local biota. The Round Stingray (Urobatis halleri) was selected as a representative elasmobranch species to perform an exploratory study on environmental pharmaceutical exposure. Archived liver samples of males and females from juvenile to adult size classes from several locations (n = 53) were examined for 18 pharmaceutical and illicit drug compounds using isotope-dilution LC-MS/MS. Very few compounds were detected in stingray livers, with diphenhydramine as the only pharmaceutical above quantitation limits. Only stingrays collected from the urban site (mainland California) had detectable levels of diphenhydramine compared to no detections in reference stingrays (offshore island). Sex and sampling location substantially influenced both detection rate and concentrations. Our results suggest that aspects of species' ecology and physiology should be considered for future studies investigating pharmaceutical exposure in elasmobranchs. PMID- 30301083 TI - Exceptional biodiversity of the cryptofaunal decapods in the Chagos Archipelago, central Indian Ocean. AB - The Chagos Archipelago is geographically remote and isolated from most direct anthropogenic pressures. Here, we quantify the abundance and diversity of decapod crustaceans inhabiting dead coral colonies, representing a standardised microhabitat, across the Archipelago. Using morphological and molecular techniques we recorded 1868 decapods from 164 nominal species within 54 dead coral colonies, but total species estimates (Chao1 estimator) calculate at least 217 species. Galatheids were the most dominant taxa, though alpheids and hippolytids were also very abundant. 32% of species were rare, and 46% of species were found at only one atoll. This prevalence of rarer species has been reported in other cryptofauna studies, suggesting these assemblages maybe comprised of low abundance species. This study provides the first estimate of diversity for reef cryptofauna in Chagos, which will serve as a useful baseline for global comparisons of coral reef biodiversity. PMID- 30301086 TI - The response of benthic foraminifera to aquaculture and industrial pollution: A case study from the Northern Persian Gulf. AB - The aquaculture and industrial sewage impacts on benthic foraminifera investigated at two reefs across the northern Persian Gulf. The foraminifera assemblages at a single sewaged reef were compared with two non-sewaged reefs. A low-diversity assemblage, dominated by stress-tolerant species Quinqueloculina sp. and larger symbiont-bearing Amphistegina sp., was characteristic of the industrial sewaged reef. The opportunistic species Ammonia sp. and Elphidium sp. were common in aquaculture sewaged reef. The density of foraminifera in sewaged reefs was lower than non-sewaged reefs. The lower diversity was only detected in the industrial sewaged reef. Assemblage structure was significantly different between sewaged and non-sewaged reefs. The industrial sewaged reef displayed high FORAM Index values (>4.0), reflecting favorable environments for supporting relatively healthy reefs. FORAM Index in aquaculture sewaged reef ranged from 2.0 to 4.0 indicated that the water with organic pollution may support living coral community, but any damage would not be followed by recovery. PMID- 30301085 TI - Urban coral reefs: Degradation and resilience of hard coral assemblages in coastal cities of East and Southeast Asia. AB - Given predicted increases in urbanization in tropical and subtropical regions, understanding the processes shaping urban coral reefs may be essential for anticipating future conservation challenges. We used a case study approach to identify unifying patterns of urban coral reefs and clarify the effects of urbanization on hard coral assemblages. Data were compiled from 11 cities throughout East and Southeast Asia, with particular focus on Singapore, Jakarta, Hong Kong, and Naha (Okinawa). Our review highlights several key characteristics of urban coral reefs, including "reef compression" (a decline in bathymetric range with increasing turbidity and decreasing water clarity over time and relative to shore), dominance by domed coral growth forms and low reef complexity, variable city-specific inshore-offshore gradients, early declines in coral cover with recent fluctuating periods of acute impacts and rapid recovery, and colonization of urban infrastructure by hard corals. We present hypotheses for urban reef community dynamics and discuss potential of ecological engineering for corals in urban areas.

AB - Vibrio parahaemolyticus, found frequently in oysters and other seafoods, is the most prevalent gastroenteritis-causing pathogen in Korea and other Asian countries. It is associated exclusively with the consumption of raw or improperly cooked contaminated seafood, especially oysters. In this study, we isolated and characterized 59 V. parahaemolyticus strains (toxR-positive) from May to October 2016 in shellfish-harvesting areas off the west coast of Korea. The results revealed that none of the isolates contained the tdh and trh toxicity genes. The multiple antibiotic resistance (MAR) value of most isolates was 0.32, but it was as high as 0.69 in one isolate strain. Moreover, when resistance to heavy metals was examined, the majority of the isolates displayed resistance to Ba2+ (98.3%), Co3+ (28.8%), Cd2+ (16.9%), and Cu2+ (13.6%). Interestingly our data revealed that tolerance to heavy metals was prevalent in the V. parahaemolyticus strains with more than two antibiotic resistance phenotypes. PMID- 30301088 TI - Increased temperature but not pCO2 levels affect early developmental and reproductive traits of the economically important habitat-forming kelp Lessonia trabeculata. AB - The effects of ocean warming and ocean acidification on developmental and reproductive traits of Lessonia trabeculata were evaluated. Meiospores were cultured for 35 days in an experimental mesocosm where temperature (~15 and 19 degrees C) and partial CO2 pressure (pCO2, ~400 and 1300 MUatm) were controlled. The results indicate that germination was reduced at 19 degrees C, whereas the increase of pCO2 only had effects at 15 degrees C. Likewise, the increase in temperature significantly affected the vegetative growth of female gametophytes. Sex ratio was not affected significantly by any of the variables studied. Fertility and reproductive success decreased by about 50% at 19 degrees C. The pCO2 levels had no significant effects on most early developmental traits. The results suggest that ocean warming or periodic warming events (e.g. an El Nino event) might affect the recruiting capacity of this or other similar species by affecting their early developmental stages. PMID- 30301089 TI - The effects of dredging and environmental conditions on concentrations of polycyclic aromatic hydrocarbons in the water column. AB - Sediment dredging can cause damage to the marine environment due to mobilization of sediments and contaminants. The effects of dredging and boundary environmental conditions on the concentration of Polycyclic Aromatic Hydrocarbons (PAHs) in water were evaluated during dredging of the Oil Port of Genoa-Multedo (Italy). Results showed that turbidity and PAH concentrations increased in the water during dredging. However, the scenario was complex due to the high number of interacting physical-chemical factors influencing PAH concentrations and transport. Due to these, PAH distribution is different in water, where low molecular-weight PAHs were predominant (maximum concentration 0.105 MUg L-1), and in bottom sediments, where high-molecular-weight PAHs had the highest concentrations (from 299.3 to 1256.5 ng g-1). Moreover, mainly during dredging the PAH concentrations in water were significantly higher inside than outside the port as a consequence of the lower dynamics within the port basin. Turbidity was the main parameter related to PAH concentrations. PMID- 30301090 TI - Evaluating the impact of sewage discharges on the marine environment with a lightweight AUV. AB - Environmental studies that use small Autonomous Underwater Vehicles (AUVs) can survey wider and deeper areas, compared to traditional methods, at a reasonable cost. Thanks to the precise vehicle navigation systems, the data collected can be accurately geolocalized. Besides, lightweight vehicles can be deployed from the shore or from small boats and programmed by means of user-friendly graphical interfaces, thus reducing and simplifying the need of human resources and infrastructures. Based on such a technology, this paper presents a framework to assess the environmental impact of a marine sewage outfall set in the Bay of Palma (Mallorca, Spain). We report the results of the analysis of the images recorded in the course of six missions conducted with an AUV. The plan was designed after a microbiological analysis detected the presence of cyanobacteria in a sample of sand and water collected by scuba divers close to the sewer pipe mouth. PMID- 30301091 TI - Calculation of oil droplet size distribution in ocean oil spills: A review. AB - Calculation of oil droplet size distribution is one of the key components of ocean oil spill models. Oil fate and transport calculations of the model are significantly impacted by the droplet size distribution. Accuracy of the model predictions heavily depend on how well the model can calculate or represent oil droplet sizes. However, in early oil spill models, the importance of oil droplet size calculation has been overlooked and they used simple empirical formulas. In recent decades, there have been some significant improvements in understanding of oil droplet size calculations. Both experimental studies as well as numerical studies have been contributed to improve oil droplet size calculations. The traditional equilibrium models have been improved while droplet dynamics models provided a different dimension to the oil DSD calculations. Thus, at this stage it is important to review the existing studies and methods of oil droplet size calculation. The objective of this paper is to review the development of oil droplet size calculation in ocean oil spill models highlighting the recent improvements. Furthermore, this paper discusses the capabilities and limitations of different approaches in calculating oil droplet size distribution in both underwater and surface oil spill models and discuss their applicability to different situations. This study will provide a good guideline for future oil spill model developments to improve the oil droplet size calculations. PMID- 30301093 TI - Oil and gas infrastructure decommissioning in marine protected areas: System complexity, analysis and challenges. AB - Many offshore oil and gas production facilities are nearing the end of their operational life, with decommissioning now becoming a global challenge. The compatibility of decommissioning operations to marine protected areas (MPAs) creates further challenges. The recently-developed DAPSI(W)R(M) problem structuring framework (covering Drivers, Activities, Pressures, State changes, Impacts (on Welfare) and Responses (as Measures)) was applied here to interrogate the complexity of decommissioning oil and gas infrastructure within MPAs, with outputs feeding into the development of a novel database tool for Screening Potential Impacts of Decommissioning Activities (SPIDA). In meeting the current requirements of the marine regulatory regime, SPIDA provides a more streamlined, evidence-based process which can be applied by industry, statutory nature conservation bodies and regulators for identifying and evaluating evidence that supports the implications of decommissioning alternatives on the condition of MPAs. SPIDA has been developed to be adapted for other activities and sectors, including offshore renewables. PMID- 30301092 TI - Marine animal forests as useful indicators of entanglement by marine litter. AB - Entanglement of marine fauna is one of the principal impacts of marine litter, with an incidence that can vary strongly according to regions, the type and the quantity of marine litter. On the seafloor, areas dominated by sessile suspension feeders, such as tropical coral reefs or deep-sea coral and sponge aggregations, have been termed "animal forests" and have a strong potential to monitor the temporal and spatial trends of entanglement by marine litter, especially fishing gears. Several characteristics of these organisms represent advantages while avoiding constraints and bias. Biological constraints and logistical aspects, including tools, are discussed to better define a strategy for supporting long term evaluation of accumulation and entanglement of marine litter. PMID- 30301094 TI - Mercury and selenium in the grass goby Zosterisessor ophiocephalus (Pisces: Gobiidae) from a mercury contaminated Mediterranean lagoon. AB - Mercury (Hg) and its bioaccumulation are important in evaluating the health risk through fish consumption. In the Marano and Grado Lagoon a historical contamination originating from both mining and industrial sources is present. In this study the Hg levels in the grass goby and the protective effect of selenium (Se) were determined as a function of size, sex, sampling sites and season. Mercury often exceeded the limit for commercialisation, whereas Se was mostly constant being homeostatically regulated. The mean Se/Hg molar ratio showed about 40% of data >1.0 and the HBVSe index was on average equal to 0.0. Thus, grass goby of this area is not a Se source food indicated for pregnant and/or breastfeeding women, but its occasional consumption would appear to have no contraindications if integrated with other Se rich foods: the ingestion of about 10 fish fillets per week can be safely consumed by adults. PMID- 30301095 TI - Petroleum hydrocarbon and microbial community structure successions in marine oil related aggregates associated with diatoms relevant for Arctic conditions. AB - Oil-related aggregates (ORAs) may contribute to the fate of oil spilled offshore. However, our understanding about the impact of diatoms and associated bacteria involved in the formation of ORAs and the fate of oil compounds in these aggregates is still limited. We investigated these processes in microcosm experiments with defined oil dispersions in seawater at 5 degrees C, employing the Arctic diatom Fragilariopsis cylindrus and its associated bacterial assemblage to promote ORA formation. Accumulation of oil compounds, as well as biodegradation of naphthalenes in ORAs and corresponding water phases, was enhanced in the presence of diatoms. Interestingly, the genus Nonlabens was predominating the bacterial communities in diatom-supplemented microcosms, while this genus was not abundant in other samples. This work elucidates the relevance of diatom biomass for the formation of ORAs, microbial community structures and biodegradation processes in chemically dispersed oil at low temperatures relevant for Arctic conditions. PMID- 30301096 TI - Polycyclic aromatic hydrocarbons in sediments of the Amazon River Estuary (Amapa, Northern Brazil): Distribution, sources and potential ecological risk. AB - The distribution, sources and potential ecological risk of priority polycyclic aromatic hydrocarbons (PAHs) in sediment from the Amazon River Estuary (Macapa and Santana, Amapa, Northern Brazil) were investigated. The total PAHs concentration (?PAH) ranged from 22.2 to 158.9 ng g-1 dw (mean value 49.4 ng g-1 dw). PAHs levels in the study area were relatively low than those in nearby areas and other coastal zones worldwide, and could be considered as baseline for PAHs in Amazonic sediments. PAHs ratios and the statistical analysis showed that fossil fuel and biomass combustions, primarily from local sources, were the dominant PAHs origins. The potential ecological risk was assessed on the basis of the sediment quality guidelines, and it was found that PAHs in the sediments of the Amazon River Estuary do not cause adverse effects on living organisms; however, the abundance of naphthalene and the presence of dibenzo[a,h]anthracene and benzo[a]pyrene deserve more attention. PMID- 30301097 TI - Environmental triggers of a Microcystis (Cyanophyceae) bloom in an artificial lagoon of Hangzhou Bay, China. AB - The relationship between Microcystis abundance and environmental variables was studied during a Microcystis bloom in the summer months of 2016 in an artificial lagoon of Hangzhou Bay, China. It was determined that Microcystis abundance increased from 0.16 * 104 cell/L to 5.8 * 107 cell/L within 17 days from 28 July to 14 August, contributing to 96.84-99.56% of the total phytoplankton abundance. Then, Microcystis gradually disappeared 57 days afterwards. The results showed that the growth of Microcystis, including the stage of recovery, outbreak, subsidence and disappearance, was significantly correlated with water temperature, salinity, soluble reactive phosphorus (PO4-P), dissolved inorganic nutrients (DIN), silicate (SiO4-Si), the ratio of DIN/SiO4-Si and zooplankton abundance, and the key environmental triggers which promoted the outbreak of Microcystis were water temperature, PO4-P concentration and zooplankton abundance in this artificial lagoon. PMID- 30301098 TI - Mercury contents in relation to biometrics and proximal composition and nutritional levels of fish eaten from the Western Mediterranean Sea (Almeria bay). AB - Total liver and muscle mercury, and muscular composition, biometrics and trophic levels, were determined in four species (Mullus surmuletus, Merluccius merluccius, Auxis rochei and Scomber japonicus) of the Mediterranean Sea (Almeria Bay, Spain). Mercury levels did not exceed the maximum residue limit, and M. merluccius obtained the highest level in muscle. Considerable variations in Hg content among individuals were observed in non-gregarious species. A positive correlation between Hg and trophic level or length was found in muscle, but not in liver. Organs (liver or muscle) with major Hg accumulation depend on species; muscle in M. merluccius and liver in S. japonicus. The results indicate that Hg levels in fish depend on intra- and interspecies factors that should be taken into account in systems to monitor Hg levels.

AB - Spatial dynamics of heavy metals (Cd, Cu, Fe, Pb, and Zn) and metalloid As were investigated along the sedimentary column, inside and outside mangrove stands, and within the upper, middle, and lower Mangawhai Estuary, New Zealand. Organic matter contents (1.89 to 17.15%) were 10 times higher inside versus outside mangroves, and decreased sharply with depth to 30 cm. Cu, Fe, and Zn were highest in the upper estuary and Pb was highest close to a road (lower estuary), reflecting road run-off. A mangrove island (lower estuary; high energy) had lowest heavy metal and highest As concentrations (resulting from high absorption of As by the carbonate rich sediments). Most of the analysed sediment parameters in our study were higher inside versus outside mangroves, suggesting the accumulation of organic matter and build up capacity to buffer pollutants. Our results show that mangrove stands tend to accumulate heavy metals and may act as natural filters of pollution of coastal waterways.

AB - In this study, the bacterial and archaeal communities along with their functions of activated sludge from three wastewater treatment plants were investigated by Illumina MiSeq Platform. The treatment processes were modified A/A/O, DE oxidation ditch and pre-anaerobic carrousel oxidation ditch, respectively. The taxonomic analyses showed that Proteobacteria was the predominant bacterial phylum, and Nitrosospira was the dominant nitrification genus. Candidatus Accumulibacter was abundant in DE oxidation ditch process, and the main archaea communities were methanosaeta-like species which had the capability to anaerobic ammonia oxidation. The results illustrated that anaerobic ammonium oxidation played an important role in the nitrogen metabolism and there might be other unknown phosphate-accumulating organisms (PAOs) performing phosphorus removal in activated sludge. The predicted function analyses indicated that both bacteria and archaea were involved in nitrification, denitrification, ammonification and phosphorus removal processes, and their relative abundance varied metabolic modules differed from each other.

AB - Passive sampling techniques were used for monitoring trace metals and polycyclic aromatic hydrocarbons (PAHs) in the seawater surrounding the Costa Concordia shipwreck (Isola del Giglio, Italy). The monitoring lasted two and a half years (2012-2014) and considered all four phases of the "parbuckling project": stabilisation of the wreckage, installation of steel caissons on both sides of the wreck, parbuckling, and refloating. Dissolved trace metals (Cd, Cr, Cu, Hg, Ni, Pb, and V) were measured with diffusive gradients in thin films (DGT), while freely dissolved PAHs were measured with semi-permeable membrane devices (SPMDs). Passive sampling allowed to detect very low concentrations of contaminants, and indicated significant differences among the sampling stations and among the different steps for salvaging the wreck. The results suggested that the main source of contamination was the heavy working vessel traffic at the disaster site, rather than the release of contaminants from the wreck. PMID- 30301101 TI - Sources and scavenging of plutonium in the East China Sea. AB - The 240Pu/239Pu atom ratio and 239+240Pu activity of seawater in the East China Sea (ECS) was measured in order to examine the Pu sources and elaborate Pu scavenging process. High 240Pu/239Pu atom ratios (0.187-0.243, average = 0.221 +/ 0.017) in the surface water and water column were observed during 2011, implying of non-global fallout Pu sources. The distribution of 240Pu/239Pu atom ratio in the ECS was in agreement with the introduction pathway of the Kuroshio, showing a decreasing trend away from the outer shelf. An even higher 240Pu/239Pu atom ratios (0.243-0.263, average = 0.253 +/- 0.007) were observed in the Kuroshio, indicating the non-global fallout Pu signal from the Pacific Proving Grounds (PPG). Using a two end-member mixing model, the Pu source from the PPG contribution was calculated to be 36 +/- 9% in the ECS seawater. The 239+240Pu activities of surface seawater were in the range of 2.00-2.95 mBq m-3 in the ECS. The spatial distribution of 239+240Pu activity in the surface seawater showed an increasing trend from the outer shelf to the nearshore. Moreover, 239+240Pu inventory of water column at the station DH23 in the ECS was calculated to be ~0.29 Bq m-2, which was 1-3 orders of magnitude lower than the estimates of sediment cores in the ECS shelf (9-407 Bq m-2). Such differences were determined by the high degree Pu scavenging efficiency in the ECS and high Pu input carried by terrestrial sediments from the Yangtze River. Finally, both 240Pu/239Pu atom ratios and 239+240Pu activities were identical before and after the Fukushima nuclear accident (FNA), suggesting that the impact of the FNA on the ECS was negligible. PMID- 30301103 TI - PAHs contamination in edible gastropods from north Patagonian harbor areas. AB - PAHs are persistent pollutants released into the environment by fossil fuels burning and leak during petroleum operations. Associated with suspended particles upon entering marine ecosystem are accumulated by benthic fauna. Human exposure occurs mainly from ingestion such as gastropods consumption. The objective was to determine PAHs in sediments and in the marine gastropod Buccinanops globulosus in sites with different maritime and urban influences. In sampling sites located 20 km from the harbor, PAHs were non-detected; while in harbor gastropods, the level of PAH4 was exceeded according to international normative. Level of dibenzo[a,h]anthracene in sediments was between the ISQG and PEL. Since these are the first results of PAHs in edible gastropods in South America, we concluded that PAHs can be dangerous for consumers according to ingestion frequency. Integrative studies are necessary to evaluate the interaction among pollutants in maritime areas and the incidence in human health due to shellfish consumption. PMID- 30301104 TI - Microplastics disturb the anthozoan-algae symbiotic relationship. AB - World production of plastic has dramatically increased from the 1950's and now it reaches approximately 311 million tons per year. The resulting accumulation of small plastic detritus less than 5 mm in size, termed "microplastics", has started threatening the life cycles of marine organisms. Here we show the first evidence that microplastics disturb the initiation of symbiotic relationships in anthozoan-algae symbiosis. We found in both the aposymbiotic sea-anemone Aiptasia sp. and the coral Favites chinensis that the infectivity of symbiotic algae into the host is severely suppressed by microspheres fed either directly or indirectly through microsphere-fed Artemia sp. Similar trends were seen when microplastics collected from commercial facewash were used instead of microspheres. Therefore, ongoing accumulation of microplastics in the ocean might disturb the healthy anthozoan-algae symbiotic relationships, which are cornerstones of the biologically enriched coral reef ecosystem. PMID- 30301105 TI - Environmental changes in Ariake Sea of Japan and their relationships with Isahaya Bay reclamation. AB - This paper reviews the recent environmental deterioration in Ariake Sea, Japan, including an increased frequency of red tides and hypoxic waters and decreased fishery production. Analysis of the mechanisms of environmental deterioration suggests that it is possibly induced by the decrease in tidal flat area, decreases in the tide and tidal current and changes in the sediment environment. The Isahaya Bay reclamation project resulted in the loss of 1550 ha of tidal flats, and is one of the possible reasons for the decreases in the tide and tidal current. Therefore, some fishermen and researchers believe that opening the reclamation project dike's floodgates is an effective environmental restoration countermeasure for Ariake Sea. However, the central government decided not to open the floodgates at present due to strong opposition from local farmers, and some researchers believe that the influences of the Isahaya Bay reclamation project on the environmental changes outside of Isahaya Bay are minor. Several lawsuits regarding these relationships and the opening of the dike's floodgates are currently under dispute. To revive Ariake Sea as a sustainable ecosystem, other countermeasures for environmental restoration are suggested and discussed in this paper. PMID- 30301106 TI - Dumping to the abyss: single-use marine litter invading bathyal plains of the Sardinian margin (Tyrrhenian Sea). AB - This study reports data on benthic litter abundance, composition and distribution obtained during deep-sea trawl surveys conducted along the Sardinian continental margin down to the bathyal plain, at depths comprised from 740 to 1740 m. None of the investigated sites was litter free. Density ranged from a minimum of 4 to a maximum of >1300 litter items per km2, with a mean value of 258 +/- 59 items. Plastic accounted for 56% of the total collected items, followed by glass (24%), metal (10%). Most items, irrespectively of the category, were single-use items. Fish abundance in all of the investigated catches was significantly higher than the number of litter items, the weight of which was similar to the reared fish biomass. Our results confirm that anthropogenic waste has reached the deep Mediterranean Sea, and that the most recent EU legislation banning single-use plastic tools represents a timely and necessary measure. PMID- 30301107 TI - Seabirds and plastics don't mix: Examining the differences in marine plastic ingestion in wedge-tailed shearwater chicks at near-shore and offshore locations. AB - Plastic ingestion by wedge-tailed shearwaters (WTS) nesting at near-shore and offshore sites along the east coast of Australia were investigated. Ingestion rates were at 20% in near-shore lavaged WTS, where the beaches were significantly more polluted, compared to 8% in birds at offshore sites. The material and colour of recovered plastics at offshore sites differed significantly between beach surveys and that ingested by seabirds in the same area. This pattern was not evident near-shore. Hence, in near-shore environments birds may feed locally and are influenced by nearby plastics, compared to birds offshore. The origins of marine debris between near-shore and offshore beaches differed; with land-based sources unsurprisingly having more influence on near-shore sites. The findings of this study indicate the need for localised data to address and manage this pollutant, with nesting seabirds at greater risk in near-shore environments. A preliminary modified ecological quality objective for WTS is presented. PMID- 30301108 TI - Type and quantity of coastal debris pollution in Taiwan: A 12-year nationwide assessment using citizen science data. AB - Man-made coastal debris pollution is a growing concern for Taiwan. In 2004, Taiwanese environmental organizations led by the "Society of Wilderness" began gathering data on 19 categories of debris items collected during cleanup events. We present our analysis of the resulting 12-year dataset collated from 541 events held between October 2004 and December 2016. In total, 904,302 items weighing 131,358.3 kg were collected, and 63.6% and 27.2% of items were made of either plastic or plastic mixed with other materials, respectively. The five most commonly recorded debris categories were plastic shopping bags, plastic bottle caps, disposable tablewares, fishing equipment, and plastic drinking straws. We estimated that during the 12-year period on average between 3.7 and 7.9 million items weighing 560-1110 metric tons polluted Taiwan's coastline. We offer recommendations for improving the quality of data collected during Taiwan's cleanup events and report some policy changes due partly to previous reports of this dataset. PMID- 30301109 TI - Thyasira tokunagai as an ecological indicator for the quality of sediment and benthic communities in the East Sea-Byeong, Korea. AB - The biomass and abundance of molluscan species were identified to evaluate the ecological quality of the surface sediment at the East Sea-Byeong ocean dumping site, Korea. To identify the dominant molluscan species, sediment samples were collected at nine selected stations during five expeditions in 2009, 2012, 2013, 2014, and 2015. In total, 16 molluscan species, including Aplacophora, Gastropoda, Bivalvia, and Scaphopoda, were observed. The bivalve Thyasira tokunagai was the dominant species, accounting for 82.6% of the total abundance of all identified species. This species was also the dominant benthic molluscan in sediments rich in organic matter and with a low manganese content. In addition, environmental variables, including sediment grain size, water depth, total organic carbon, and heavy metals, were found to be critical drivers affecting the spatial distribution of molluscan species.

AB - The purpose of this article is to study, result of metal concentration in two sediment cores from Persian Gulf. Age of sediment is determined by C14 isotope method and bulk concentration is determined by ICP. This research output shows that, age of BandareAbbas core back to 9660 and Bushehr core to 15,600 years ago. Also,concentration in BandareAbbas and Bushehr cores respectively change as, As (1.08-11.76 Vs 5.2-13.09), Ba (15.03-129.5 Vs 73.9-120.4), Cd (0.09-0.46 Vs 0.09 0.18), Li (5.66-58.5 Vs 15.3-33.4), Mo (0.3-0.75 Vs 0.3-0.8), Mg (7928.4-15,503.9 Vs 13,102.8-17,227.8), Mn (110.6-566.4 Vs 279.3-429.1), Na (8905.47-27,993.3 Vs 9357.7-27,541.4), Ni (13.3-110.3 Vs 37.1-88.4), Pb (0.5-42.5 Vs 2.5-13.6), Sr (407.5-1773.2 Vs 440.3-1596.9), Zn (13.05-71.2Vs22.4-50.5), Fe (0.46-4.07 Vs 1.7 3.18), Ca (9.25-23.3 Vs 13.8-19.2) and Al (0.62-8.15 Vs 2.48-4.65). Moreover different pollution index investigation represent that except Ca, the rest of the metal elements do not show pollution. PMID- 30301111 TI - Occurrence of microplastics in fishes from two landing sites in Tuticorin, South east coast of India. AB - Microplastics pollution of the marine environment has been reported worldwide. Here, we investigate the occurrence of microplastics in two species of fishes namely Rastrilleger kanagurta and Epinephalus merra bought from Thirespuram and Punnakayal fish landing sites at Tuticorin. Out of the total 40 fish, 12 fish showed the presence of microplastic particulates in the intestine. The particulates included microfibers (80%) in red, black and translucent colors and irregularly shaped microplastic fragments (20%). The microplastics were identified as Polyethylene and Polypropylene by Fourier Transform Infrared Radiation analysis. Though microplastics were detected in the gut of the species, the risk of transfer due to consumption can be safely ruled out as the fish are degutted prior to consumption here. Presence of microplastics in the Tuticorin coast is a matter of concern due to its proximity to the Gulf of Mannar, a sensitive coral reef patch already threatened by marine pollution. PMID- 30301112 TI - Similarities and differences of 137Cs distributions in the marine environments of the Baltic and Black seas and off the Fukushima Dai-ichi nuclear power plant in model assessments. AB - The compartment model POSEIDON-R with an embedded food web model was used to assess 137Cs distributions in the Baltic and Black seas and off the Pacific coast of Japan during 1945-2020 due to the weapon testing and accidents at the Chernobyl and Fukushima Dai-ichi nuclear power plants. The results of simulations conducted with generic parameters agreed well with measurements of 137Cs concentrations in the water, bottom sediments, and in fish. In the Black and Baltic seas, salinity variations affected the transfer of 137Cs through the food web. The contamination of pelagic fish followed the water contamination with some delay, whereas demersal fish depuration was found to be related to decreasing 137Cs concentrations in the upper sediment layer. On the Pacific shelf off Japan, intensive currents and eddies caused the simulated depuration rates in fish to be one-two orders of magnitude larger than those in the semi-enclosed Black and Baltic seas. PMID- 30301113 TI - Trace metal concentrations in the muscle of seven marine species: Comparison between the Gulf of Lions (North-West Mediterranean Sea) and the Bay of Biscay (North-East Atlantic Ocean). AB - Concentrations of 6 trace metals (Ag, Cd, Cu, Ni, Pb, Zn) in the muscle of 2 sharks (Galeus melastomus and Scyliorhinus canicula), 4 teleosts (Helicolenus dactylopterus, Lepidorhombus boscii, Micromesistius poutassou and Phycis blennoides) and 1 crustacean (Nephrops norvegicus) were compared between the Bay of Biscay (Atlantic Ocean) and the Gulf of Lions (Mediterranean Sea). Although average concentrations and the trace element pollution index were generally higher in the Gulf of Lions, significant differences between the two ecosystems were only found for Zn for Helicolenus dactylopterus, and for Ag and Cu for the crustacean N. norvegicus. Moreover, some relationships between trophic level or size and metal concentrations were found for these two species. The absence of clear pattern may result from the blurring effect of contamination and excretion that may act differentially for all species and all elements. PMID- 30301114 TI - Distribution, composition, and ecological risk of surface sedimental polychlorinated naphthalenes in the East China Sea. AB - To reveal the pollution levels and estimate the ecological risks of polychlorinated naphthalenes (PCNs) in the East China Sea (ECS), seventy-five surface sediment samples were collected and analyzed by high-resolution mass spectrometry. PCN contents ranged from below detection limit to 261.71 ng/g dry weight (d.w.), with an integrally seaward decreasing trend. Mono-, tetra-, and hepta-CNs were the dominant homologs, and CN-2, CN-73, and CN-75 were the major individual components in most samples. CN-2 presented an obvious boundary with lower contents (16.48 +/- 3.40 ng/g d.w.) in the center of the study area and higher contents (50.88 +/- 10.39 ng/g d.w.) in the north and south of the boundary. The toxic equivalent (TEQ) contents ranged from 0 to 0.212 ng/g, and CN 2 and CN-73 were the predominant contributors to the TEQ. PMID- 30301115 TI - Nitrogen and sulfur isotopes predict variation in mercury levels in Arctic seabird prey. AB - Mercury (Hg) biotransformation and biomagnification are processes that affect Hg burdens in wildlife. To interpret variation in Hg in seabird eggs, used as Hg bioindicators in the Arctic, it is important to understand how Hg biomagnifies through the food web. We evaluated the use of delta34S, along with other commonly used stable isotope signatures (delta15N and delta13C), for the determination of possible sources of Hg in an Arctic food web (56 individuals of 15 species of fish and invertebrates). Hg correlated with delta34S (R2 = 0.72). When the combined effects of delta34S and delta15N were considered in mixed-effects models, both delta34S and delta15N together described Hg patterns in Arctic food webs better than either isotope alone. Our results demonstrate the usefulness of delta34S to account for variation in Hg among marine animals and to study the possible underlying effects that MeHg production may have on Hg pathways in Arctic ecosystems. PMID- 30301116 TI - Risk assessment of oil spills in the Chinese Bohai Sea for prevention and readiness. AB - Oil spill accidents occur with increasing frequency in the Chinese Bohai Sea because of the presence of extensive number of oil platforms and oil pipelines the Chinese Bohai region. An appropriate risk assessment for oil spill prevention and readiness is necessary. Risk assessment for the entire Chinese Bohai Sea based on a quantitative method is proposed. We created a hypothetical simulation of oil spill trajectories based on an oil spill model for 28 oil platforms in the Chinese Bohai region in 2010. Then, we mapped a risk index in the study areas based on a combination of oil spill trajectories and shoreline susceptibility data. Five high-risk areas were identified in the entire Chinese Bohai Sea. Detailed suggestions for prevention and readiness are described here. These results can help in developing a risk assessment of oil spills in the Chinese Bohai Sea and serve as a useful analytic tool for slick-related emergencies. PMID- 30301117 TI - Background levels of trace elements in brown and red seaweeds from Trindade, a remote island in South Atlantic Ocean. AB - Trace elements in organisms are normally higher in well-developed coastal areas than on oceanic islands. Few studies have used seaweeds as their sentinels on islands. This study established background levels of trace elements (As, Cd, Pb, Zn, Cu and Hg) for four seaweed species (Dictyopteris delicatula and Canistrocarpus cervicornis, brown algae; Ceratodictyon variabile and Palisada perforata, red algae) from Trindade, an oceanic Brazilian island, and verified potential differences associated to distinct environmental conditions. Spatial differences were not detected for As, Hg and Cd in samples, although the highest concentrations of these elements were observed in brown seaweeds. The highest Zn, Pb and Cu concentrations in seaweeds from the only inhabited beach may be a signal of the onset of human footprints on this still pristine, remote island. By comparison with background described in the literature, concentrations of trace elements in seaweeds were low, thus, allowing them to be considered reference levels. PMID- 30301118 TI - Microplastics in Galway Bay: A comparison of sampling and separation methods. AB - Microplastics, an emerging pollutant, are recognised as having a ubiquitous distribution in the environment. Currently several benthic sampling tools are being employed to collect subtidal marine sediment, however, there are no comparative studies on the efficiency of these tools to sample for microplastics or the subsequent extraction methods of microplastics from these marine sediments. This study addresses these knowledge gaps by comparing commonly applied benthic sampling tools (Van Veen grab, box corer, gravity corer) and a variety of density separation methods (elutriation column, sodium chloride solution, sodium tungstate dihydrate solution) for microplastic collection and processing. Each sampling tool was tested at the same station and the collected sediment was used to assess the extraction performance for the different density separation techniques. No statistically significant differences were found between the concentrations of microplastics extracted for any of the sampling tools. However, there were significant differences between the density separation methods using sodium tungstate dihydrate and sodium chloride solution and the elutriation method. This preliminary study provides evidence that the sampling tools tested are both suitable and proficient at determining the abundance of microplastics in sediments. Sodium tungstate dihydrate proved to be a novel and feasible option for dense liquid separation of microplastics in subtidal marine sediments. These results will allow for more confidence in data quality when comparing future surveys applying different benthic sampling tools. PMID- 30301119 TI - Sediment characteristics influence the fertilisation success of the corals Acropora tenuis and Acropora millepora. AB - Elevated suspended sediment concentrations (SSCs) often impact coral fertilisation success, but sediment composition can influence effect thresholds, which is problematic for accurately predicting risk. Here, we derived concentration-response thresholds and cause-effect pathways for SSCs comprising a range of realistic mineral and organic compositions on coral fertilisation success. Effect concentration thresholds (EC10: 10% fertilisation inhibition) varied markedly, with fertilisation highly sensitive to inshore organic-clay rich sediments and bentonite clay at <5 mg L-1. Mineral clays and organic matter within these sediments likely promoted flocculation of the coral sperm, which in turn reduced fertilisation. In contrast, sediments lacking these properties bound less sperm, leading to higher SSC thresholds for coral fertilisation (EC10 > 40 mg L-1). The effect thresholds for relevant sediment types were combined with in situ turbidity data from locations near dredging operations to assess the risks posed by dredging to coral fertilisation at these locations. PMID- 30301120 TI - Macrobenthic community characteristics and ecological health of a constructed intertidal oyster reef in the Yangtze Estuary, China. AB - Development of substrate organisms (oysters, barnacles) and the health of a monitored oyster reef were investigated in the Yangtze Estuary. Very low salinity suppressed oyster survival. Nevertheless, middle- to high-salinity significantly increased the abundance and biomass of substrate organisms, and macrobenthos species and diversity. Long-term variation in substrate organisms was steady after a major fluctuation, yet the macrobenthic community structure lagged behind that of oysters. Overall, the oyster reef was in a healthy state. The M-AMBI results showed that its ecological status under high-salinity was better than medium-salinity conditions. Redundancy analysis indicated these results were associated with changes in water salinity and substrate factors. Taken together, our results suggest this constructed intertidal oyster reef has had a positive effect on the community and health status of macrobenthos in the Yangtze Estuary. Further, these ecological benefits increased going from medium- to high-salinity waters, but were generally absent under low salinity. PMID- 30301121 TI - Simulated fate of catchment-derived sediment on the Great Barrier Reef shelf. AB - Numerical experiments using a 3D model of fine sediment transport in the Great Barrier Reef region indicate deposition of the bulk mass of catchment sediments from river plumes within a few tens of kilometres from river mouths. A very fine fraction of easily resuspended catchment sediment has a capacity to propagate over much greater distances reaching out into the mid-shelf and outer-shelf regions. The model suggests such particles, instrumental to the development of low density flocs in the marine environment, can play a critical role in altering optical properties of water masses over the shelf during wet years. The mid-term (4 year) impact of Great Barrier Reef catchments on the probability of suspended sediment concentration exceeding the ecologically significant trigger value of 2 mg/L is confined to inshore regions adjacent to river mouth locations. PMID- 30301122 TI - An online platform for rapid oil outflow assessment from grounded tankers for pollution response. AB - The risk of oil spills is an ongoing societal concern. Whereas several decision support systems exist for predicting the fate and drift of spilled oil, there is a lack of accurate models for assessing the amount of oil spilled and its temporal evolution. In order to close this gap, this paper presents an online platform for the fast assessment of tanker grounding accidents in terms of structural damage and time-dependent amount of spilled cargo oil. The simulation platform consists of the definition of accidental scenarios; the assessment of the grounding damage and the prediction of the time-dependent oil spill size. The performance of this integrated online simulation environment is exemplified through illustrative case studies representing two plausible accidental grounding scenarios in the Gulf of Finland: one resulting in oil spill of about 50 t, while in the other the inner hull remained intact and no spill occurred. PMID- 30301123 TI - Environmental regeneration processes in the Anthropocene: The Bilbao estuary case (northern Spain). AB - This work tackles a multidisciplinary study on the recent sedimentary record of the Bilbao estuary (northern Spain), which is the backbone of a city that was primarily industrial and now is widely recognized as a successful example of urban transformation. Although hotspots of heavily polluted materials still remain at the mouth of the two main tributaries (Galindo and Gobelas), the data obtained confirm the ongoing formation of a new layer of sediments (here called "postindustrial zone") covering historically polluted and azoic deposits. It is characterized by largely variable levels of metals and magnetic susceptibility and moderate-to-high abundances of benthic foraminifera. Monitoring of the evolution of this layer appears a key factor to assess environmental improvement and decision-making in polluted estuaries. PMID- 30301124 TI - Biomonitoring coastal environments with transplanted macroalgae: A methodological review. AB - The use of macroalgae transplants is a recent technique used in pollution biomonitoring studies in marine ecosystems. Only 60 articles published between 1978 and 2017 reported the use of this environmental tool for the active biomonitoring of inorganic pollutants and nutrients worldwide. In this review paper, we evaluated studies on this topic in relation to the development of methodological aspects of the technique and the degree of standardization of the protocols used. On the basis of findings of this review, we conclude that the technique is not yet standardized and that uniformisation of protocols is required to enable comparison of the results of different studies. We propose a new protocol for applying the technique, in which each suggestion has been carefully and rigorously compared with the relevant findings reported in the available literature.

Phylogenetic proximity of any of the NHP species to Homo sapiens assures that much better translatability of research outcomes from model studies involving human diseases can be achieved than from those generated with other pre-clinical systems. Our group and others used during past two decades NHPs in research directed towards viral and autoimmune disorders of the gastrointestinal tract. This review summarizes progress made in the area of enteric viral infections including its applicability to human disease. PMID- 30301126 TI - The Effect of Extensive Human Presence at an Early Age on Stress Responses and Reactivity of Juvenile Ostriches towards Humans. AB - The effect of extensive human presence and regular gentle handling performed at an early age (0-3 months old) on stress responses and reactivity of juvenile ostriches towards humans was investigated. A total of 416 ostrich chicks over two years were exposed to one of three treatments for three months after hatching; namely, Human Presence 1 (HP1, N = 144): extensive/prolonged human presence with physical contact (touch, stroking), gentle human voice, and visual stimuli; Human Presence 2 (HP2, N = 136): extensive/prolonged human presence without physical contact, but with gentle human voice and visual stimuli; and the Standard treatment (S, N = 136): human presence limited to routine feed and water supply as a control. At 7.5 months of age, the plasma heterophil/lymphocyte (H/L) ratio was measured before and 72 h after feather harvesting and feather clipping to determine acute stress responses, while chronic stress was measured by quantification of corticosterone (CORT) concentrations in the floss feathers of the birds. Birds' behavioural response towards a familiar or an unfamiliar handler was evaluated at 12 months using docility and fear tests, and through behavioural observations conducted on random days between the ages of 8-13 months. Willingness to approach, and to allow touch interactions, aggressiveness, and exhibition of sexual display towards the handler, was recorded. No difference in the H/L ratios before and after feather harvesting and clipping was observed in HP1 birds, whereas H/L ratios showed a significant increase 72 h post feather harvesting and clipping in HP2 and S birds (p < 0.05). Birds from the S treatment exhibited a significantly (p < 0.05) higher feather CORT concentration compared with HP1 birds, while HP2 birds had intermediate responses. Birds' reactivity towards humans and temperament as evaluated using behavioural observations, docility, and fear tests was not affected by treatment (p > 0.05). However, HP1 and HP2 birds were more inclined (p < 0.05) to approach a familiar rather than an unfamiliar handler during the behavioural observations, indicating an ability to distinguish between a familiar and an unfamiliar handler. Overall, the results indicate that early gentle human interactions with ostrich chicks can be beneficial in reducing physiological stress sensitivity later in life and facilitate the ability of ostriches to distinguish between familiar and unfamiliar handlers.

AB - Regular cocoa consumption has been shown to improve blood pressure (BP), insulin sensitivity, and lipid levels in patients with type 2 diabetes (T2D), using up to 100 g of chocolate or 54 g of cocoa. These effects, attributed to cocoa flavanols, would be beneficial for patients with T2D if they could be achieved by a usual serving size of flavanol-rich cocoa. Forty-two hypertensive patients with T2D (stable pharmacological treatment, with good adjustment for glucose metabolism, lipids, and BP) ingested capsules with 2.5 g/day of a flavanol-rich cocoa or cocoa-free capsules for 12 weeks in a double-blinded, randomized, placebo-controlled study with parallel group design. Participants had to maintain diet, lifestyle, and medication. Before and after intervention, fasting blood samples were collected; BP and nutritional status were investigated. Cocoa treatment did not affect BP, nor glucose metabolism (glucose, HbA1c, insulin, HOMA-IR) and lipids (triglycerides, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol). Body weight, fat mass, and nutrient supply remained unchanged. Changes in the placebo group did not occur. Regular intake of a usual serving size of flavanol-rich cocoa does not improve cardiometabolic parameters in stably treated patients with T2D and hypertension. As the medication modulates partly the same targets as cocoa flavanols, future studies should focus on the preventive effect of cocoa against diabetes and other cardiometabolic diseases in individuals with preexisting abnormalities that do not require any pharmacological treatment.

AB - We previously reported that maternal protein restriction (LP) during pregnancy increases salt sensitivity in offspring using the Stroke-Prone Spontaneously Hypertensive Rat (SHRSP). In the present study, we focus on DNA methylation profiles of prostaglandin E receptor 1 gene (ptger1), which is known to be associated with hypertension. We evaluated the ptger1 DNA methylation status via bisulfite sequencing, and analyzed the expression of ptger1-related genes. The results of these analyses showed that, compared to controls, the LP-S offspring exhibited both marked ptger1 hypermethylation, and significantly increased ptger1 expression. Moreover, they also exhibited significantly decreased expression of the downstream gene epithelial Na+ channel alpha (enacalpha). Interestingly, LP offspring that were provided with a standard water drinking supply (W) also exhibited increased ptger1 methylation and expression. Together, these results suggest that maternal protein restriction during pregnancy modulates the renal ptger1 DNA methylation state in SHRSP offspring, and thereby likely mediates ptger1 and enacalpha gene expression to induce salt sensitivity. PMID- 30301129 TI - Ironing out the Details: Untangling Dietary Iron and Genetic Background in Diabetes. AB - The search for genetic risk factors in type-II diabetes has been hindered by a failure to consider dietary variables. Dietary nutrients impact metabolic disease risk and severity and are essential to maintaining metabolic health. Genetic variation between individuals confers differences in metabolism, which directly impacts response to diet. Most studies attempting to identify genetic risk factors in disease fail to incorporate dietary components, and thus are ill equipped to capture the breadth of the genome's impact on metabolism. Understanding how genetic background interacts with nutrients holds the key to predicting and preventing metabolic diseases through the implementation of personalized nutrition. Dysregulation of iron homeostasis is associated with type II diabetes, but the link between dietary iron and metabolic dysfunction is poorly defined. High iron burden in adipose tissue induces insulin resistance, but the mechanisms underlying adipose iron accumulation remain unknown. Hepcidin controls dietary iron absorption and distribution in metabolic tissues, but it is unknown whether genetic variation influencing hepcidin expression modifies susceptibility to dietary iron-induced insulin resistance. This review highlights discoveries concerning the axis of iron homeostasis and adipose function and suggests that genetic variation underlying dietary iron metabolism is an understudied component of metabolic disease.

Correspondingly, insufficient zinc intake in early youth can detrimentally affect the function of a growing body. The aim of this study was to determine zinc content in breast milk among lactating women in Latvia and factors (maternal diet; mother's and baby's characteristics; breastfeeding pattern) affecting it. METHODS: In total, 62 mature milk (at least one month postpartum) samples were collected and pooled within 24 h. Zinc content (mg 100 mL-1) was determined using inductively coupled plasma mass spectrometry (ICP-MS; Agilent 7700*, Agilent Technologies, Tokyo, Japan). RESULTS: Zinc content in mature breast milk ranged from 0.01 to 0.34 mg 100 mL-1 with a median (interquartile range) content of 0.10 (0.05-0.15) mg 100 mL-1. Time postpartum was a significant negative predictor for zinc content in breast milk (r = -0.500; p = 0.000). Median maternal zinc intake was 10.70 (7.24-15.27) mg. Yet, zinc content in breast milk was unaffected by maternal dietary zinc intake (r = 0.155; p = 0.221). CONCLUSIONS: Maternal dietary zinc intake was nearly the recommended intake for lactating women (11 mg), but due to low zinc content in breast milk, babies in Latvia might not receive sufficient zinc intake. Future research should aim for the assessment of zinc status by evaluating plasma or serum levels of both mothers and babies. PMID- 30301131 TI - Are Clean Eating Blogs a Source of Healthy Recipes? A Comparative Study of the Nutrient Composition of Foods with and without Clean Eating Claims. AB - Food blogs are an increasingly popular source of information about food and nutrition. There is a perception that foods published on clean eating blogs, which promote unprocessed foods, are healthier than comparable foods without these claims. However, foods with these claims and their nutrient composition have not previously been evaluated. The purpose of the study was to describe the nutritional content of clean eating recipes compared to recipes without clean eating claims and the nutritional guidelines published by the World Health Organisation (WHO). Clean eating recipes were systematically selected from 13 popular clean eating blogs and were described and compared with control recipes without clean eating claims. The nutrient profiles from the included recipes were summarised and evaluated against criteria from WHO recommendations for chronic disease prevention and criteria from the U.K. Food Standards Agency. Data for 86 clean eating recipes were extracted that represented five food categories: breakfast, snacks, treats, desserts, and smoothies. These were matched with 86 control recipes without clean eating claims. The clean eating recipes, per portion, provide the equivalent of 15% of daily energy intake. The average serving sizes were not significantly different between clean eating and control recipes. Overall, the clean eating recipes contained significantly more protein (8.1 +/- 7.3 g vs. 5.7 +/- 4.1 g, p = 0.01), fat (15.8 +/- 10.6 g vs. 12.4 +/- 9.3 g, p = 0.03), and fibre (5.0 +/- 4.3 g vs. 2.8 +/- 2.9 g, p < 0.01) per serving than control recipes. There were no significant differences between clean eating and control recipes with respect to the energy (1280 +/- 714 kJ vs. 1137 +/- 600 kJ, p = 0.16), carbohydrate (31.5 +/- 27.3 g vs. 33.9 +/- 19.4 g, p = 0.51), sugar (21.1 +/- 20.9 g vs. 23.2 +/- 14.9 g, p = 0.46), and sodium content (196.7 +/- 269 vs. 155.8 +/- 160.8, p = 0.23). Less than 10% of clean eating and control recipes met the WHO constraints for proportions of energy from fat and sugar intake. A simulated nutrient profile of an average clean and control recipe shows that nutrients for both are similarly classified as moderate to high in fat, saturated fat, salt, and sugar. Foods with clean eating claims contained the same amount of energy, sugar, and sodium as foods without those claims. Clean eating claims are potentially misleading for consumers who may believe these foods are healthy alternatives, potentially undermining people's efforts to eat a healthy diet.

AB - The filling of channels in porous media with particles of a material can be interpreted in a first approximation as a packing of spheres in cylindrical recipients. Numerous studies on micro- and nanoscopic scales show that they are, as a rule, not ideal cylinders. In this paper, the channels, which have an irregular shape and a circular cross-section, as well as the packing algorithms are investigated. Five patterns of channel shapes are detected to represent any irregular porous structures. A novel heuristic packing algorithm for monosized spheres and different irregularities is proposed. It begins with an initial configuration based on an fcc unit cell and the subsequent densification of the obtained structure by shaking and gravity procedures. A verification of the algorithm was carried out for nine sinusoidal axisymmetric channels with different Dmin/Dmax ratio by MATLAB(r) simulations, reaching a packing fraction of at least 0.67 (for sphere diameters of 5%Dmin or less), superior to a random close packing density. The maximum packing fraction was 73.01% for a channel with a ratio of Dmin/Dmax = 0.1 and a sphere size of 5%Dmin. For sphere diameters of 50%Dmin or larger, it was possible to increase the packing factor after applying shaking and gravity movements. PMID- 30301132 TI - The Gliocentric Brain. AB - The Neuron Doctrine, the cornerstone of research on normal and abnormal brain functions for over a century, has failed to discern the basis of complex cognitive functions. The location and mechanisms of memory storage and recall, consciousness, and learning, remain enigmatic. The purpose of this article is to critically review the Neuron Doctrine in light of empirical data over the past three decades. Similarly, the central role of the synapse and associated neural networks, as well as ancillary hypotheses, such as gamma synchrony and cortical minicolumns, are critically examined. It is concluded that each is fundamentally flawed and that, over the past three decades, the study of non-neuronal cells, particularly astrocytes, has shown that virtually all functions ascribed to neurons are largely the result of direct or indirect actions of glia continuously interacting with neurons and neural networks. Recognition of non-neural cells in higher brain functions is extremely important. The strict adherence of purely neurocentric ideas, deeply ingrained in the great majority of neuroscientists, remains a detriment to understanding normal and abnormal brain functions. By broadening brain information processing beyond neurons, progress in understanding higher level brain functions, as well as neurodegenerative and neurodevelopmental disorders, will progress beyond the impasse that has been evident for decades. PMID- 30301134 TI - Differential Effect of Cobalt and Chromium Ions as Well as CoCr Particles on the Expression of Osteogenic Markers and Osteoblast Function. AB - The balance of bone formation and resorption is the result of a regulated crosstalk between osteoblasts, osteoclasts, and osteocytes. Inflammation, mechanical load, and external stimuli modulate this system. Exposure of bone cells to metal ions or wear particles are thought to cause osteolysis via activation of osteoclasts and inhibition of osteoblast activity. Co2+ ions have been shown to impair osteoblast function and the expression of the three transforming growth factor (TGF)-beta isoforms. The current study was performed to analyze how Co2+ and Cr3+ influence the expression, proliferation, and migration profile of osteoblast-like cells. The influence of Co2+, Cr3+, and CoCr particles on gene expression was analyzed using an osteogenesis PCR Array. The expression of different members of the TGF-beta signaling cascade were down regulated by Co2+, as well as several TGF-beta regulated collagens, however, Cr3+ had no effect. CoCr particles partially affected similar genes as the Co2+treatment. Total collagen production of Co2+ treated osteoblasts was reduced, which can be explained by the reduced expression levels of various collagens. While proliferation of MG63 cells appears unaffected by Co2+, the migration capacity was impaired. Our data may improve the knowledge of changes in gene expression patterns, and the proliferation and migration effects caused by artificial materials. PMID- 30301135 TI - Impact of Rehabilitation on Outcomes after TAVI: A Preliminary Study. AB - The benefit of rehabilitation in elderly patients undergoing transcatheter aortic valve implantation (TAVI) for treatment of severe aortic stenosis is unknown. The impact of declining rehabilitation programs on mortality has also not been described. In a longitudinal cohort study of 1056 patients undergoing elective TAVI between 2008 and 2016, logistic regression analysis was used to assess the relationship between treatment modality and outcome according to whether or not patients participated in a three-week rehabilitation program after TAVI. Subgroup analyses included patient outcome separated according to cardiac, geriatric, or no rehabilitation. A total of 1017 patients survived until hospital discharge (96.3%) and were offered rehabilitation, 366 patients (36.0%) declined to undergo rehabilitation, with the remaining patients undergoing either cardiac (n = 435; 42.8%) or geriatric rehabilitation (n = 216; 21.2%). Mortality at six months was lower for patients receiving rehabilitation compared with those who had not (adjusted odds ratio (OR): 0.49; 95% confidence interval (confidence interval [CI]: 0.25-0.94; p = 0.032). Sub-analysis showed the benefit of cardiac (adjusted OR: 0.31; 95% CI 0.14-0.71, p = 0.006), but not geriatric rehabilitation (adjusted OR 0.83; 95% CI 0.37-1.85, p = 0.65). A program of rehabilitation after TAVI has the potential to reduce mortality. Future studies should focus on health orientated behavior and identifying risk factors for declining rehabilitation programs. PMID- 30301136 TI - Paired CRISPR/Cas9 Nickases Mediate Efficient Site-Specific Integration of F9 into rDNA Locus of Mouse ESCs. AB - Hemophilia B (HB) is an X-linked recessive bleeding disorder, caused by F9 gene deficiency. Gene therapy combined with the CRISPR/Cas9 technology offers a potential cure for hemophilia B. Now the Cas9 nickase (Cas9n) shows a great advantage in reducing off-target effect compared with wild-type Cas9. In this study, we found that in the multicopy ribosomal DNA (rDNA) locus, the homology directed recombination (HDR) efficiency induced by sgRNA-Cas9n was much higher than sgRNA-Cas9, meanwhile without off-target in six predicted sites. After co transfection into mESCs with sgRNA-Cas9n and a non-viral rDNA targeting vector pMrnF9, harboring the homology donor template and the human F9 expression cassette, a recombination efficiency of 66.7% was achieved and all targeted clones were confirmed to be site-specific integration of F9 in the rDNA locus by PCR and southern blotting. Targeted mESCs retained the main pluripotent properties and were then differentiated into hepatic progenitor like cells (HPLCs) and mature hepatocytes, which were characterized by hepatic markers and functional assays. Importantly, the differentiated cells could transcribe exogenous F9 and secrete coagulation factor IX (FIX) proteins, suggesting active transcription and stable inheritance of transgenes in the rDNA locus. After intrasplenical transplantation in severe combined immune deficiency (SCID) mice, targeted HPLCs could survive and migrate from spleen to liver, resulting in secretion of exogenous FIX into blood. In summary, we demonstrate an efficient and site-specific gene targeting strategy in rDNA locus for stem cell-based gene therapy for hemophilia B. PMID- 30301138 TI - Significance of Brownian Motion for Nanoparticle and Virus Capture in Nanocellulose-Based Filter Paper. AB - Pressure-dependent breakthrough of nanobioparticles in filtration was observed and it was related to depend on both convective forces due to flow and diffusion as a result of Brownian motion. The aim of this work was to investigate the significance of Brownian motion on nanoparticle and virus capture in a nanocellulose-based virus removal filter paper through theoretical modeling and filtration experiments. Local flow velocities in the pores of the filter paper were modeled through two different approaches (i.e., with the Hagen-Poiseuille equation) and by evaluating the superficial linear flow velocity through the filter. Simulations by solving the Langevin equation for 5 nm gold particles and 28 nm PhiX174 bacteriophages showed that hydrodynamic constraint is favored for larger particles. Filtration of gold nanoparticles showed no difference in retention for the investigated fluxes, as predicted by the modeling of local flow velocities. Filtration of PhiX174 bacteriophages exhibited a higher retention at higher filtration pressure, which was predicted to some extent by the Hagen Poiseuille equation but not by evaluation of the superficial linear velocity. In all, the hydrodynamic theory was shown able to explain some of the observations during filtration. PMID- 30301137 TI - Peroxiredoxins in Colorectal Cancer: Predictive Biomarkers of Radiation Response and Therapeutic Targets to Increase Radiation Sensitivity? AB - Colorectal cancer (CRC) is the third most common cancer in the Western world, with one-third of cases located in the rectum. Preoperative radiotherapy is the standard of care for many patients with rectal cancer but has a highly variable response rate. The ability to predict response would be of great clinical utility. The response of cells to ionizing radiation is known to involve immediate damage to biomolecules and more sustained disruption of redox homeostasis leading to cell death. The peroxiredoxins are an important group of thiol-dependent antioxidants involved in protecting cells from oxidative stress and regulating signaling pathways involved in cellular responses to oxidative stress. All six human peroxiredoxins have shown increased expression in CRC and may be associated with clinicopathological features and tumor response to ionizing radiation. Peroxiredoxins can act as markers of oxidative stress in various biological systems but they have not been investigated in this capacity in CRC. As such, there is currently insufficient evidence to support the role of peroxiredoxins as clinical biomarkers, but it is an area worthy of investigation. Future research should focus on the in vivo response of rectal cancer to radiotherapy and the redox status of peroxiredoxins in rectal cancer cells, in order to predict response to radiotherapy. The peroxiredoxin system is also a potential therapeutic target for CRC.

AB - Fucosterol from edible brown seaweeds has various biological activities, including anti-inflammatory, anti-adipogenic, antiphotoaging, anti acetylcholinesterase, and anti-beta-secretase 1 activities. However, little is known about its effects on soluble amyloid beta peptide (sAbeta)-induced endoplasmic reticulum (ER) stress and cognitive impairment. Fucosterol was isolated from the edible brown seaweed Ecklonia stolonifera, and its neuroprotective effects were analyzed in primary hippocampal neurons and in aging rats. Fucosterol attenuated sAbeta1-42-induced decrease in the viability of hippocampal neurons and downregulated sAbeta1-42-induced increase in glucose regulated protein 78 (GRP78) expression in hippocampal neurons via activation of tyrosine receptor kinase B-mediated ERK1/2 signaling. Fucosterol co-infusion attenuated sAbeta1-42-induced cognitive impairment in aging rats via downregulation of GRP78 expression and upregulation of mature brain-derived neurotrophic factor expression in the dentate gyrus. Fucosterol might be beneficial for the management of cognitive dysfunction via suppression of aging induced ER stress. PMID- 30301142 TI - Gut Microbiota and Iron: The Crucial Actors in Health and Disease. AB - Iron (Fe) is a highly ample metal on planet earth (~35% of the Earth's mass) and is particularly essential for most life forms, including from bacteria to mammals. Nonetheless, iron deficiency is highly prevalent in developing countries, and oral administration of this metal is so far the most effective treatment for human beings. Notably, the excessive amount of unabsorbed iron leave unappreciated side effects at the highly interactive host-microbe interface of the human gastrointestinal tract. Recent advances in elucidating the molecular basis of interactions between iron and gut microbiota shed new light(s) on the health and pathogenesis of intestinal inflammatory diseases. We here aim to present the dynamic modulation of intestinal microbiota by iron availability, and conversely, the influence on dietary iron absorption in the gut. The central part of this review is intended to summarize our current understanding about the effects of luminal iron on host-microbe interactions in the context of human health and disease. PMID- 30301141 TI - In Field Fruit Sizing Using A Smart Phone Application. AB - In field (on tree) fruit sizing has value in assessing crop health and for yield estimation. As the mobile phone is a sensor and communication rich device carried by almost all farm staff, an Android application ("FruitSize") was developed for measurement of fruit size in field using the phone camera, with a typical assessment rate of 240 fruit per hour achieved. The application was based on imaging of fruit against a backboard with a scale using a mobile phone, with operational limits set on camera to object plane angle and camera to object distance. Image processing and object segmentation techniques available in the OpenCV library were used to segment the fruit from background in images to obtain fruit sizes. Phone camera parameters were accessed to allow calculation of fruit size, with camera to fruit perimeter distance obtained from fruit allometric relationships between fruit thickness and width. Phone geolocation data was also accessed, allowing for mapping fruits of data. Under controlled lighting, RMSEs of 3.4, 3.8, 2.4, and 2.0 mm were achieved in estimation of avocado, mandarin, navel orange, and apple fruit diameter, respectively. For mango fruit, RMSEs of 5.3 and 3.7 mm were achieved on length and width, benchmarked to manual caliper measurements, under controlled lighting, and RMSEs of 5.5 and 4.6 mm were obtained in-field under ambient lighting. PMID- 30301143 TI - Role of Natural Volatiles and Essential Oils in Extending Shelf Life and Controlling Postharvest Microorganisms of Small Fruits. AB - Small fruits are a multi-billion dollar industry in the US, and are economically important in many other countries. However, they are perishable and susceptible to physiological disorders and biological damage. Food safety and fruit quality are the major concerns of the food chain from farm to consumer, especially with increasing regulations in recent years. At present, the industry depends on pesticides and fungicides to control food spoilage organisms. However, due to consumer concerns and increasing demand for safer produce, efforts are being made to identify eco-friendly compounds that can extend the shelf life of small fruits. Most volatiles and essential oils produced by plants are safe for humans and the environment, and lots of research has been conducted to test the in vitro efficacy of single-compound volatiles or multi-compound essential oils on various microorganisms. However, there are not many reports on their in vivo (in storage) and In situ (in the field) applications. In this review, we discuss the efficacy, minimum inhibitory concentrations, and mechanisms of action of volatiles and essential oils that control microorganisms (bacteria and fungi) on small fruits such as strawberries, raspberries, blueberries, blackberries, and grapes under the three conditions. PMID- 30301139 TI - Crosstalk between NF-kappaB and Nucleoli in the Regulation of Cellular Homeostasis. AB - Nucleoli are emerging as key sensors of cellular stress and regulators of the downstream consequences on proliferation, metabolism, senescence, and apoptosis. NF-kappaB signalling is activated in response to a similar plethora of stresses, which leads to modulation of cell growth and death programs. While nucleolar and NF-kappaB pathways are distinct, it is increasingly apparent that they converge at multiple levels. Exposure of cells to certain insults causes a specific type of nucleolar stress that is characterised by degradation of the PolI complex component, TIF-IA, and increased nucleolar size. Recent studies have shown that this atypical nucleolar stress lies upstream of cytosolic IkappaB degradation and NF-kappaB nuclear translocation. Under these stress conditions, the RelA component of NF-kappaB accumulates within functionally altered nucleoli to trigger a nucleophosmin dependent, apoptotic pathway. In this review, we will discuss these points of crosstalk and their relevance to anti-tumour mechanism of aspirin and small molecule CDK4 inhibitors. We will also briefly the discuss how crosstalk between nucleoli and NF-kappaB signalling may be more broadly relevant to the regulation of cellular homeostasis and how it may be exploited for therapeutic purpose. PMID- 30301144 TI - Microenvironmental pH and Exosome Levels Interplay in Human Cancer Cell Lines of Different Histotypes. AB - Exosomes are extracellular nanovesicles primarily involved in the pathogenesis of many diseases including cancer. This study was set out from recent evidence that extracellular acidity may increase the exosome release by cancer cells. However, this preliminary evidence did not provide solid information on whether the pH dependent exosome over-release represents a common feature of all cancers. To the purpose of demonstrating that cancer acidity is a major determinant in inducing an increased exosome release by human cancer cells, we evaluated human tumor cell lines deriving from either colon, breast, prostate cancers, melanoma, or osteosarcoma. All cell lines were cultured in either the current 7.4 pH or the typical pH of cancer that is 6.5. The levels of released extracellular vesicles were measured by protein counts, nanoparticle tracking analysis (NTA), and nanoscale flow cytometry. The results showed that pH 6.5 induced a remarkable increase in exosome release, and buffering the medium significantly reduced the exosome release in all cancers. With these results, we provide, for the first time, evidence that tumor acidity and exosome levels represent common cancer phenotypes. PMID- 30301145 TI - Calculating Intake of Dietary Risk Components Used in the Global Burden of Disease Studies from the What We Eat in America/National Health and Nutrition Examination Surveys. AB - Disability adjusted life years (DALYs) is a health burden metric that combines years of life lost due to disease disability and premature mortality. The Global Burden of Disease (GBD) has been using DALYs to determine the health burden associated with numerous health risks, including risks associated with dietary intakes, at the global and national level. To translate such information at the food level in the U.S., variables in What We Eat in America (WWEIA) need to be aligned with those in the GBD. In this paper, we develop the necessary new variables needed to account for differences in definitions and units between WWEIA and the GBD. We use the Food Patterns Equivalents Database, Food Patterns Equivalents Ingredient Database, Food and Nutrient Database for Dietary Studies, and Standard Reference databases that provide data for WWEIA to develop food group and nutrient variables that align with definitions and units used in the GBD. Considerable effort was needed to disaggregate mixed dishes to GBD components. We also developed a new "non-starchy" vegetable variable, since the GBD vegetables do not include potatoes and corn, and we report fruits and vegetables in grams instead of household measures. New fiber variables were created to avoid double counting of fiber from legumes, whole grains, fruits, and vegetables. Regression analyses were used to predict trans-fat content for foods in WWEIA with missing or incomplete information. The majority of foods in various U.S. Department of Agriculture (USDA) categories contain multiple GBD food groups (e.g., vegetables, whole grains, and processed meat). For most nutrients considered in the GBD, composition is more evenly distributed across the main food categories; however, seafood omega-3 fats were predominantly from either protein foods or mixed dishes and sugar sweetened beverages were from a single category. Dietary intakes in the U.S. fall short of recommendations for all food groups/nutrients with established theoretical minimum-risk targets in GBD. To our knowledge, this is the first approach that aligns WWEIA intake variables with those used in the health burden-based GBD reports. These methods will facilitate researchers to begin comparing data from the U.S. with that from other countries, as well as assess food sustainability performances by concomitantly evaluating DALYs for environmental and nutritional impacts. PMID- 30301146 TI - Molecular Targets Modulated by Fangchinoline in Tumor Cells and Preclinical Models. AB - Despite tremendous progress made during the last few decades in the treatment options for cancer, compounds isolated from Mother Nature remain the mainstay for therapy of various malignancies. Fangchinoline, initially isolated from the dried root of Stephaniae tetrandrine, has been found to exhibit diverse pharmacological effects including significant anticancer activities both in tumor cell lines and selected preclinical models. This alkaloid appears to act by modulating the activation of various important oncogenic molecules involved in tumorigenesis leading to a significant decrease in aberrant proliferation, survival and metastasis of tumor cells. This mini-review briefly describes the potential effects of fangchinoline on important hallmarks of cancer and highlights the molecular targets modulated by this alkaloid in various tumor cell lines and preclinical models. PMID- 30301147 TI - Prostaglandin D2 Induces Ca2+ Sensitization of Contraction without Affecting Cytosolic Ca2+ Level in Bronchial Smooth Muscle. AB - Prostaglandin D2 (PGD2) is one of the key lipid mediators of allergic airway inflammation, including bronchial asthma. However, the role of PGD2 in the pathogenesis of asthma is not fully understood. In the present study, the effect of PGD2 on smooth muscle contractility of the airways was determined to elucidate its role in the development of airway hyperresponsiveness (AHR). In isolated bronchial smooth muscles (BSMs) of naive mice, application of PGD2 (10-9-10-5 M) had no effect on the baseline tension. However, when the tissues were precontracted partially with 30 mM K+ (in the presence of 10-6 M atropine), PGD2 markedly augmented the contraction induced by the high K+ depolarization. The PGD2-induced augmentation of contraction was significantly inhibited both by 10-6 M laropiprant (a selective DP1 antagonist) and 10-7 M Y-27632 (a Rho-kinase inhibitor), indicating that a DP1 receptor-mediated activation of Rho-kinase is involved in the PGD2-induced BSM hyperresponsiveness. Indeed, the GTP-RhoA pull down assay revealed an increase in active form of RhoA in the PGD2-treated mouse BSMs. On the other hand, in the high K+-depolarized cultured human BSM cells, PGD2 caused no further increase in cytosolic Ca2+ concentration. These findings suggest that PGD2 causes RhoA/Rho-kinase-mediated Ca2+ sensitization of BSM contraction to augment its contractility. Increased PGD2 level in the airways might be a cause of the AHR in asthma. PMID- 30301148 TI - Tailoring of Magnetic Properties of NiO/Ni Composite Particles Fabricated by Pulsed Laser Irradiation. AB - We present NiO/Ni composite particles with face-centered cubic (fcc) structure prepared by a pulsed laser irradiation of NiO nanoparticles dispersed in liquid. The sizes of particles and the Ni content in NiO/Ni composites were controlled by tuning the laser parameters, such as laser fluence and irradiation time. We found that the weight fraction of Ni has a significant impact on magnetic properties of composite particles. Large exchange bias (HEB) and coercivity field (HC) were observed at 5 K due to the creation of heterojunctions at interfaces of ferromagnetic Ni and antiferromagnetic NiO. For the NiO/Ni composites with 80% of NiO we have observed the largest values of exchange bias (175 Oe) and coercive field (950 Oe), but the increase of Ni weight fraction resulted in the decrease of both HC and HEB values. PMID- 30301149 TI - Knockdown of LXRalpha Inhibits Goat Intramuscular Preadipocyte Differentiation. AB - Goat intramuscular fat (IMF) content is mainly determined by the processes of intramuscular preadipocytes adipogenic differentiation and mature adipocyte lipid accumulation. However, the underlying regulators of these biological processes remain largely unknown. Here, we report that the expression of Liver X receptor alpha (LXRalpha) reaches a peak at early stage and then gradually decreases during goat intramuscular adipogenesis. Knockdown of LXRalpha mediated by two independent siRNAs significantly inhibits intramuscular adipocytes lipid accumulation and upregulates preadipocytes marker- preadipocyte factor 1 (pref1) expression. Consistently, siRNA treatments robustly decrease mRNA level of adipogenic related genes, including CCAAT enhancer binding protein alpha (Cebpalpha), Peroxisome proliferator activated receptor gamma (Pparg), Sterol regulatory element binding protein isoform 1c (Srebp1c), Fatty acids binding protein (aP2) and Lipoprotein lipase (Lpl). Next, adenovirus overexpression of LXRalpha does not affect intramuscular adipocytes adipogenesis manifested by Oil Red O signal measurement and adipogenic specific genes detection. Mechanically, we found that both CCAAT enhancer binding protein beta (Cebpbeta) and Kruppel like factor 8 (Klf8) are potential targets of LXRalpha, indicated by having putative binding sites of LXRalpha at the promoter of these genes and similar expression pattern during adipogenesis comparing to LXRalpha. Importantly, mRNA levels of Cebpbeta and Klf8 are downregulated significantly in goat LXRalpha knockdown intramuscular adipocyte. These results demonstrate that loss function of LXRalpha inhibits intramuscular adipogenesis possibly through down-regulation of Cebpbeta and Klf8. Our research will provide new insights into mechanical regulation of goat IMF deposition. PMID- 30301150 TI - Ganoderma tsugae Inhibits the SREBP-1/AR Axis Leading to Suppression of Cell Growth and Activation of Apoptosis in Prostate Cancer Cells. AB - Recent research suggests that the activation of lipid biosynthesis (lipogenesis) is linked with prostate cancer (PCa) malignancy. Sterol regulatory element binding protein-1 (SREBP-1) is a key transcriptional regulator controlling lipogenesis. Moreover, androgen receptor (AR) has been well defined to play an important role in lethal PCa aggressiveness from androgen-responsive to castration-resistant status. In this study, we showed that the quality-assured Ganoderma tsugae ethanol extract (GTEE), a Chinese natural and herbal product, significantly inhibited expression of SREBP-1 and its downstream genes associated with lipogenesis in PCa cells. Through inhibiting SREBP-1, GTEE reduced the levels of intracellular fatty acids and lipids in PCa cells. Importantly, GTEE also downregulated the expression of AR and prostate-specific antigen (PSA) in both androgen-responsive and castration-resistant PCa cells. By blocking the SREBP-1/AR axis, GTEE suppressed cell growth and progressive behaviors, as well as activating the caspase-dependent apoptotic pathway in PCa cells. These data provide a new molecular basis of GTEE for the development of a potential therapeutic approach to treat PCa malignancy. PMID- 30301152 TI - Tumor-Stroma Cross-Talk in Human Pancreatic Ductal Adenocarcinoma: A Focus on the Effect of the Extracellular Matrix on Tumor Cell Phenotype and Invasive Potential. AB - The extracellular matrix (ECM) in the tumor microenvironment modulates the cancer cell phenotype, especially in pancreatic ductal adenocarcinoma (PDAC), a tumor characterized by an intense desmoplastic reaction. Because the epithelial-to mesenchymal transition (EMT), a process that provides cancer cells with a metastatic phenotype, plays an important role in PDAC progression, the authors aimed to explore in vitro the interactions between human PDAC cells and ECM components of the PDAC microenvironment, focusing on the expression of EMT markers and matrix metalloproteinases (MMPs) that are able to digest the basement membrane during tumor invasion. EMT markers and the invasive potential of HPAF II, HPAC, and PL45 cells grown on different ECM substrates (fibronectin, laminin, and collagen) were analyzed. While N-cadherin, alphaSMA, and type I collagen were not significantly affected by ECM components, the E-cadherin/beta-catenin complex was highly expressed in all the experimental conditions, and E-cadherin was upregulated by collagen in PL45 cells. Cell migration was unaffected by fibronectin and delayed by laminin. In contrast, collagen significantly stimulated cell migration and the secretion of MMPs. This study's results showed that ECM components impacted cell migration and invasive potential differently. Collagen exerted a more evident effect, providing new insights into the understanding of the intricate interplay between ECM molecules and cancer cells, in order to find novel therapeutic targets for PDAC treatment. PMID- 30301151 TI - Dietary Patterns in Primary School are of Prospective Relevance for the Development of Body Composition in Two German Pediatric Populations. AB - This study performed comparative analyses in two pediatric cohorts to identify dietary patterns during primary school years and examined their relevance to body composition development. Nutritional and anthropometric data at the beginning of primary school and two or four years later were available from 298 and 372 participants of IDEFICS-Germany (Identification and prevention of Dietary-induced and lifestyle-induced health Effects In Children and infants Study) and the KOPS (Kiel Obesity Prevention Study) cohort, respectively. Principal component analyses (PCA) and reduced rank regression (RRR) were used to identify dietary patterns at baseline and patterns of change in food group intake during primary school years. RRR extracted patterns explaining variations in changes in body mass index (BMI), fat mass index (FMI), and waist-to-height-ratio (WtHR). Associations between pattern adherence and excess gain in BMI, FMI, or WtHR (>75th percentile) during primary school years were examined using logistic regression. Among PCA patterns, only a change towards a more Mediterranean food choice during primary school years were associated with a favorable body composition development in IDEFICS-Germany (p < 0.05). In KOPS, RRR patterns characterized by a frequent consumption of fast foods or starchy carbohydrate foods were consistently associated with an excess gain in BMI and WtHR (all p < 0.005). In IDEFICS-Germany, excess gain in BMI, FMI, and WtHR were predicted by a frequent consumption of nuts, meat, and pizza at baseline and a decrease in the consumption frequency of protein sources and snack carbohydrates during primary school years (all p < 0.01). The study confirms an adverse impact of fast food consumption on body composition during primary school years. Combinations of protein and carbohydrate sources deserve further investigation. PMID- 30301153 TI - Synthesis and Evaluation of Novel Ligustrazine Derivatives as Multi-Targeted Inhibitors for the Treatment of Alzheimer's Disease. AB - A series of novel ligustrazine derivatives 8a-r were designed, synthesized, and evaluated as multi-targeted inhibitors for anti-Alzheimer's disease (AD) drug discovery. The results showed that most of them exhibited a potent ability to inhibit both ChEs, with a high selectivity towards AChE. In particular, compounds 8q and 8r had the greatest inhibitory abilities for AChE, with IC50 values of 1.39 and 0.25 nM, respectively, and the highest selectivity towards AChE (for 8q, IC50 BuChE/IC50 AChE = 2.91 * 106; for 8r, IC50 BuChE/IC50 AChE = 1.32 * 107). Of note, 8q and 8r also presented potent inhibitory activities against Abeta aggregation, with IC50 values of 17.36 uM and 49.14 uM, respectively. Further cellular experiments demonstrated that the potent compounds 8q and 8r had no obvious cytotoxicity in either HepG2 cells or SH-SY5Y cells, even at a high concentration of 500 MUM. Besides, a combined Lineweaver-Burk plot and molecular docking study revealed that these compounds might act as mixed-type inhibitors to exhibit such effects via selectively targeting both the catalytic active site (CAS) and the peripheral anionic site (PAS) of AChEs. Taken together, these results suggested that further development of these compounds should be of great interest. PMID- 30301154 TI - Fine-Scale Source Apportionment Including Diesel-Related Elemental and Organic Constituents of PM2.5 across Downtown Pittsburgh. AB - Health effects of fine particulate matter (PM2.5) may vary by composition, and the characterization of constituents may help to identify key PM2.5 sources, such as diesel, distributed across an urban area. The composition of diesel particulate matter (DPM) is complicated, and elemental and organic carbon are often used as surrogates. Examining multiple elemental and organic constituents across urban sites, however, may better capture variation in diesel-related impacts, and help to more clearly separate diesel from other sources. We designed a "super-saturation" monitoring campaign of 36 sites to capture spatial variance in PM2.5 and elemental and organic constituents across the downtown Pittsburgh core (~2.8 km2). Elemental composition was assessed via inductively-coupled plasma mass spectrometry (ICP-MS), organic and elemental carbon via thermal optical reflectance, and organic compounds via thermal desorption gas chromatography mass-spectrometry (TD-GCMS). Factor analysis was performed including all constituents-both stratified by, and merged across, seasons. Spatial patterning in the resultant factors was examined using land use regression (LUR) modelling to corroborate factor interpretations. We identified diesel-related factors in both seasons; for winter, we identified a five-factor solution, describing a bus and truck-related factor [black carbon (BC), fluoranthene, nitrogen dioxide (NO2), pyrene, total carbon] and a fuel oil combustion factor (nickel, vanadium). For summer, we identified a nine-factor solution, which included a bus-related factor (benzo[ghi]fluoranthene, chromium, chrysene, fluoranthene, manganese, pyrene, total carbon, total elemental carbon, zinc) and a truck-related factor (benz[a]anthracene, BC, hopanes, NO2, total PAHs, total steranes). Geographic information system (GIS)-based emissions source covariates identified via LUR modelling roughly corroborated factor interpretations. PMID- 30301155 TI - Life Course Effects of Socioeconomic and Lifestyle Factors on Metabolic Syndrome and 10-Year Risk of Cardiovascular Disease: A Longitudinal Study in Taiwan Adults. AB - The objective of the study was to explore the dynamic effects of socioeconomic status (SES) and lifestyle behaviors on the risks of metabolic syndrome (MS) or cardiovascular disease (CVD) in life course. The data of 12,825 subjects (6616 males and 6209 females) who underwent repeated examinations and answered repeated questionnaires from 2006 to 2014 at the Major Health Screening Center in Taiwan, was collected and analyzed. The trajectory of trends in the subjects' SES and lifestyle mobility over time was observed, and the effects of factors with potential impacts on health were tested and analyzed using multiple logistic regression and a generalized estimated equation model. A 10% increase in MS prevalence was observed over the nine-year period. The average Framingham CVD score for people with MS was estimated to be about 1.4% (SD = 1.5%). Except for middle-aged women, marriage was found to raise the risk of CVD, whereas increasing education and work promotions independently reduced CVD risk for the majority of subjects. However, the risk of CVD was raised by half for young men who had a job or lost a job in comparison to continuously unemployed young men. Physical activity was only found to be advantageous for disease prevention in those aged less than 40 years; increased exercise levels were useless for reducing CVD risk among older men. Alcohol drinking and betel chewing caused increased CVD risk in the old and young subjects, respectively, whereas vegetarian diets and vitamin C/E intake were helpful in preventing CVD, even if those habits were ceased in later life. For middle-aged women, getting sufficient sleep reduced CVD risk. We concluded that SES and lifestyle behaviors may have different effects on health over time, among various populations. Accordingly, suggestions can be provided to healthcare workers in designing health promotion courses for people at different life stages. PMID- 30301156 TI - Pulse Ultrasonic Cure Monitoring of the Pultrusion Process. AB - This article discusses the results of a series of experiments on pulse ultrasonic cure monitoring of carbon fiber reinforced plastics applied to the pultrusion process. The aim of this study is to validate the hypothesis that pulse ultrasonic cure monitoring can be applied (a) for profiles having small cross sections such as 7 mm * 0.5 m m and (b) within the environment of the pultrusion process. Ultrasonic transducers are adhesively bonded to the pultrusion tool as actuators and sensors. The time-of-flight and the amplitude of an ultrasonic wave are analyzed to deduce the current curing state of the epoxy matrix. The experimental results show that ultrasonic cure monitoring is indeed applicable even to very thin cross sections. However, significant challenges can be reported when the techniques are used during the pultrusion process. PMID- 30301157 TI - Non-Stationary Platform Inverse Synthetic Aperture Radar Maneuvering Target Imaging Based on Phase Retrieval. AB - As a powerful signal processing tool for imaging moving targets, placing radar on a non-stationary platform (such as an aerostat) is a future direction of Inverse Synthetic Aperture Radar (ISAR) systems. However, more phase errors are introduced into the received signal due to the instability of the radar platform, making it difficult for popular algorithms to accurately perform motion compensation, which leads to severe effects in the resultant ISAR images. Moreover, maneuvering targets may have complex motion whose motion parameters are unknown to radar systems. To overcome the issue of non-stationary platform ISAR autofocus imaging, a high-resolution imaging method based on the phase retrieval principle is proposed in this paper. Firstly, based on the spatial geometric and echo models of the ISAR maneuvering target, we can deduce that the radial motion of the radar platform or the vibration does not affect the modulus of the ISAR echo signal, which provides a theoretical basis for the phase recovery theory for the ISAR imaging. Then, we propose an oversampling smoothness (OSS) phase retrieval algorithm with prior information, namely, the phase of the blurred image obtained by the classical imaging algorithm replaces the initial random phase in the original OSS algorithm. In addition, the size of the support domain of the OSS algorithm is set with respect to the blurred target image. Experimental simulation shows that compared with classical imaging methods, the proposed method can obtain the resultant motion-compensated ISAR image without estimating the radar platform and maneuvering target motion parameters, wherein the fictitious target is perfectly focused. PMID- 30301158 TI - Effect of Cetylpyridinium Chloride (CPC) on Colony Formation of Common Nontuberculous Mycobacteria. AB - Cetylpyridinium chloride (CPC) is widely used to decontaminate water samples for the cultivation of nontuberculous mycobacteria (NTM). The rationale for using CPC is that it kills more non mycobacteria than NTM and thereby prevents the outgrowth and detection of mycobacterial colonies on solid media. The few CPC susceptibility measurements that have been published, suggest that CPC decontamination does kill significant numbers of NTM. We confirm that observation here and further demonstrate that CPC-susceptibility varied significantly by one log between representative NTM species and between strains of the same species. CPC-susceptibility was the same for cells collected from cultures or water acclimated (P = 0.6485, T-test) and CPC-susceptibility was relatively similar over the range of commonly employed CPC dosages. We conclude that use of CPC as decontaminating agent may lead to failure to recover an NTM isolate and considerable underestimates of NTM numbers. PMID- 30301159 TI - The Acute Effects of Foam Rolling on Fatigue-Related Impairments of Muscular Performance. AB - The purpose of this study was to examine the effects of self-myofascial release (MFR) via foam rolling immediately following strenuous activity on acute fatigue related impairments of muscular performance. Healthy male (n = 16) and female (n = 9) subjects visited the laboratory three separate times. During visit 1, subjects were familiarized with performance testing procedures and the foam rolling and fatigue protocols. For visits 2 and 3, subjects were (T1) assessed for vertical jump height, velocity, and power and dynamic reaction time (DRT). Subjects then performed the exercise fatigue protocol, followed by either a foam rolling treatment (MFR) or seated rest (CON). Immediately after, subjects repeated the performance tests (T2). CON resulted in a greater percent decline from T1-T2 for average power (p = 0.03), average velocity (p = 0.02), and peak power (p = 0.03) than the MFR treatment. No between-treatment differences were detected for %? vertical jump height (p = 0.14) or DRT (p = 0.20). According to magnitude-based inference analysis, MFR is likely beneficial in attenuating fatigue-induced kinematic decrements (i.e., power and velocity). Based on magnitude-based inference analysis, MFR is "possibly beneficial" with respect to mitigating acute fatigue-related impairment of jump height and dynamic reaction time. Results demonstrate the plausible short-term benefits of foam rolling on muscular performance decrements associated with acute muscular fatigue from exercise. PMID- 30301160 TI - Evaluation of Intensity of Sleep Bruxism in Arterial Hypertension. AB - Sleep bruxism (SB) is a masticatory muscle activity during sleep that is characterized as rhythmic (phasic) or non-rhythmic (tonic). The recent hypothesis on the etiology of SB supports the role of the central and autonomic nervous systems. Therefore, in this study, we aimed to assess the intensity of SB in patients with arterial hypertension. A total of 70 adults participated in this study: 35 patients with hypertension (study group) and 35 normotensive subjects (control group). Data were recorded using home portable cardiorespiratory polygraphy. The bruxism episode index (BEI) in the study group was found to be significantly higher compared to the control group (3.4 +/- 3.25 vs. 2.35 +/- 2.29, p = 0.04). Hypertension, higher body mass index (BMI), lower values of mean oxygen saturation (SpO2), and a higher percentage of SpO2 < 90% constituted independent risk factors for increased BEI. These results suggest the need for special oral care in hypertensive patients, patients with higher BMI, lower values of SpO2 and a higher percentage of SpO2 < 90%. PMID- 30301161 TI - A Marine Diterpenoid Modulates the Proteasome Activity in Murine Macrophages Stimulated with LPS. AB - The proteasome is an intracellular complex that degrades damaged or unfolded proteins and participates in the regulation of several processes. The immunoproteasome is a specialized form that is expressed in response to proinflammatory signals and is particularly abundant in immune cells. In a previous work, we found an anti-inflammatory effect in a diterpenoid extracted from the octocoral Pseudopterogorgia acerosa, here called compound 1. This compound prevented the degradation of inhibitor kappaB alpha (IkappaBalpha) and the subsequent activation of nuclear factor kappaB (NFkappaB), suggesting that this effect might be due to inhibition of the ubiquitin-proteasome system. Here we show that compound 1 inhibits the proteasomal chymotrypsin-like activity (CTL) of murine macrophages in the presence of lipopolysaccharide (LPS) but not in its absence. This effect might be due to the capacity of this compound to inhibit the activity of purified immunoproteasome. The compound inhibits the cell surface expression of major histocompatibility complex (MHC)-I molecules and the production of proinflammatory cytokines induced by LPS in vitro and in vivo, respectively. Molecular docking simulations predicted that compound 1 selectively binds to the catalytic site of immunoproteasome subunits beta1i and beta5i, which are responsible for the CTL activity. Taken together these findings suggest that the compound could be a selective inhibitor of the immunoproteasome, and hence could pave the way for its future evaluation as a candidate for the treatment of inflammatory disorders and autoimmune diseases. PMID- 30301162 TI - Elucidating Functions of FleQ in Xanthomonas oryzae pv. oryzae by Comparative Proteomic and Phenotypic Analyses. AB - To acclimate to different environments, gene expression has to be controlled using diverse transcriptional activators. FleQ activates sigma54-dependent transcription initiation and regulates flagellar biosynthesis and other mechanisms in several bacteria. Xanthomonas oryzae pv. oryzae (Xoo), which is a causal agent of bacterial leaf blight on rice, lacking FleQ loses swimming motility and virulence is not altered. However, other biological mechanisms related with FleQ in Xoo are unknown. In this study, we generated the FleQ overexpressing strain, Xoo(FleQ), and knockout mutant, XooDeltafleQ. To predict the mechanisms affected by FleQ, label-free shotgun comparative proteomics was carried out. Based on proteomic results, we performed diverse phenotypic assays. Xoo(FleQ) had reduced ability to elicit disease symptoms and exopolysaccharide production. Additionally, the ability of XooDeltafleQ(EV) (empty vector) and Xoo(FleQ) to form biofilm was decreased. Swarming motility of XooDeltafleQ(EV) was abolished, but was only reduced for Xoo(FleQ). Additionally, abnormal twitching motility was observed in both strains. Siderophore production of Xoo(FleQ) was enhanced in iron-rich conditions. The proteomic and phenotypic analyses revealed that FleQ is involved in flagellar-dependent motility and other mechanisms, including symptom development, twitching motility, exopolysaccharide production, biofilm formation, and siderophore production. Thus, this study provides fundamental information about a sigma54-dependent transcription activator in Xoo. PMID- 30301163 TI - Unliganded Progesterone Receptor Governs Estrogen Receptor Gene Expression by Regulating DNA Methylation in Breast Cancer Cells. AB - Breast cancer prognosis and response to endocrine therapy strongly depends on the expression of the estrogen and progesterone receptors (ER and PR, respectively). Although much is known about ERalpha gene (ESR1) regulation after hormonal stimulation, how it is regulated in hormone-free condition is not fully understood. We used ER-/PR-positive breast cancer cells to investigate the role of PR in ESR1 regulation in the absence of hormones. We show that PR binds to the low-methylated ESR1 promoter and maintains both gene expression and DNA methylation of the ESR1 locus in hormone-deprived breast cancer cells. Depletion of PR reduces ESR1 expression, with a concomitant increase in gene promoter methylation. The high amount of methylation in the ESR1 promoter of PR-depleted cells persists after the stable re-expression of PR and inhibits PR binding to this genomic region. As a consequence, the rescue of PR expression in PR-depleted cells is insufficient to restore ESR1 expression. Consistently, DNA methylation impedes PR binding to consensus progesterone responsive elements. These findings contribute to understanding the complex crosstalk between PR and ER and suggest that the analysis of ESR1 promoter methylation in breast cancer cells can help to design more appropriate targeted therapies for breast cancer patients. PMID- 30301165 TI - Seasonal Change in Distribution and Heat Coma Temperature of Oceanic Skaters, Halobates (Insecta, Heteroptera: Gerridae). AB - A series of studies were conducted during two cruises between Tokyo and Honolulu in September 2010 and from February to March 2012. The aims of the studies were to (1) compare the distribution of three species of Halobates oceanic skaters, H. germanus, H. micans, and H. sericeus, with respect to their temperature limits; (2) identify the lower temperature limit of H. sericeus, the species that displays the widest distribution range (40 degrees N-35 degrees S) latitude; and (3) test the hypothesis that H. sericeus can change their temperature tolerance to adapt to seasonal changes in sea surface temperatures. The heat coma temperature (HCT) was measured during the two cruises and the values were compared between the two populations of H. sericeus. The species collected in September 2010 were H. germanus, H. micans, and H. sericeus. H. sericeus was dominant, occupying more than 90% of the collecting sites. H. germanus and H. micans were collected in the northern and western part of the cruise track (29-34 degrees N, 141-151 degrees E), and not in the southern and eastern part. The population density of these two species was 9000-150,000/km2 in the first cruise, which took place in summer. On the other hand, H. sericeus was collected throughout the cruise track during that cruise. The population density of H. sericeus was relatively high, at 4000-310,000/km2, in the southern and eastern part of the cruise track (19-29 degrees N, 152 degrees E-165 degrees W). In February and March 2012, only H. sericeus was collected at a density of 17,000 80,000/km2 and only in the eastern and southern part, at 25 degrees -28 degrees N, 169 degrees E-178 degrees W. No Halobates oceanic skaters were found in the western or northern part (30 degrees N and further north, 159 degrees E and further west) during that cruise. The lower limit for the inhabitation of sea surface temperatures appeared to be 27.8 degrees C or slightly lower for H. germanus and H. micans, but was 22.1 degrees C or slightly lower for H. sericeus. H. sericeus specimens, mostly adults, that had been collected during the two cruises were used in heat coma experiments. Summer specimens showed significantly higher heat coma temperatures (HCTs) than the winter specimens. This difference in HCTs may be the result of relatively long term temperature acclimation in the summer or winter for the adults that inhabit the temperate and subtropical areas along the cruise tracks between Tokyo and Honolulu in the Pacific Ocean. This temperature plasticity of H. sericeus may be related to the wider latitude area inhabited by this species (main range: 40 degrees N-25 degrees S). PMID- 30301166 TI - Dispersal in Host-Parasitoid Interactions: Crop Colonization by Pests and Specialist Enemies. AB - Interactions of insect pests and their natural enemies increasingly are being considered from a metapopulation perspective, with focus on movements of individuals among habitat patches (e.g., individual crop fields). Biological control may be undercut in short-lived crops as natural enemies lag behind the pests in colonizing newly created habitat. This hypothesis was tested by assessing parasitism of cereal leaf beetle (Oulema melanopus) and alfalfa weevil (Hypera postica) larvae at varying distances along transects into newly planted fields of small grains and alfalfa in northern Utah. The rate of parasitism of cereal leaf beetles and alfalfa weevils by their host-specific parasitoids (Tetrastichus julis (Eulophidae) and Bathyplectes curculionis (Ichneumonidae), respectively) was determined for earliest maturing first generation host larvae. Rates of parasitism did not vary significantly with increasing distance into a newly planted field (up to 250-700 m in individual experiments) from the nearest source field from which pest and parasitoid adults may have immigrated. These results indicate strong, rapid dispersal of the parasitoids in pursuing their prey into new habitat. Thus, across the fragmented agricultural landscape of northern Utah, neither the cereal leaf beetle nor the alfalfa weevil initially gained substantial spatial refuge from parasitism by more strongly dispersing than their natural enemies into newly created habitat. Additional studies, including those of colonization of newly planted crops by generalist pests and natural enemies, are called for in assessing these results with a broader perspective. PMID- 30301164 TI - Comprehensive Description of Fusarium graminearum Pigments and Related Compounds. AB - Several studies have explored in depth the biochemistry and genetics of the pigments present in Fusarium graminearum, but there is a need to discuss their relationship with the mold's observable surface color pattern variation throughout its lifecycle. Furthermore, they require basic cataloguing, including a description of their major features known so far. Colors are a viable alternative to size measurement in growth studies. When grown on yeast extract agar (YEA) at 25 degrees C, F. graminearum initially exhibits a whitish mycelium, developing into a yellow-orange mold by the sixth day and then turning into wine-red. The colors are likely due to accumulation of the golden yellow polyketide aurofusarin and the red rubrofusarin, but the carotenoid neurosporaxanthin also possibly plays a major role in the yellow or orange coloration. Torulene might contribute to red tones, but it perhaps ends up being converted into neurosporaxanthin. Culmorin is also present, but it does not contribute to the color, though it was initially isolated in pigment studies. Additionally, there is the 5-deoxybostrycoidin-based melanin, but it mostly occurs in the teleomorph's perithecium. There is still a need to chemically quantify the pigments throughout the lifecycle, and analyze their relationships and how much each impacts F. graminearum's surface color. PMID- 30301167 TI - Microbiota and Phage Therapy: Future Challenges in Medicine. AB - An imbalance of bacterial quantity and quality of gut microbiota has been linked to several pathologies. New strategies of microbiota manipulation have been developed such as fecal microbiota transplantation (FMT); the use of pre/probiotics; an appropriate diet; and phage therapy. The presence of bacteriophages has been largely underestimated and their presence is a relevant component for the microbiome equilibrium. As a promising treatment, phage therapy has been extensively used in Eastern Europe to reduce pathogenic bacteria and has arisen as a new method to modulate microbiota diversity. Phages have been selected and "trained" to infect a wide spectrum of bacteria or tailored to infect specific antibiotic resistant bacteria present in patients. The new development of genetically modified phages may be an efficient tool to treat the gut microbiota dysbiosis associated with different pathologies and increased production of bacterial metabolites and subsequently decrease systemic low-grade chronic inflammation associated with chronic diseases. Microbiota quality and mitochondria dynamics can be remodulated and manipulated by phages to restore the equilibrium and homeostasis of the system. Our aim is to highlight the great interest for phages not only to eliminate and control pathogenic bacterial infection but also in the near future to modulate the microbiota by adding new functions to selected bacteria species and rebalance the dynamic among phages and bacteria. The challenge for the medicine of tomorrow is to re-think and redesign strategies differently and far from our traditional thinking. PMID- 30301168 TI - Challenge Studies to Determine the Ability of Foods to Support the Growth of Listeria monocytogenes. AB - : Listeria monocytogenes is a foodborne pathogen that causes listeriosis, a relatively rare, but potentially fatal, disease, with a mortality rate of 20-30%. In general, European Regulations require the absence of L. monocytogenes in five samples of 25 g before the food has left the producer, but if the food has been demonstrated not to support the growth of L. monocytogenes, up to 100 cfu g-1 are allowed in the food (except for foods for infants or medical purposes) during its shelf-life under reasonably foreseeable storage conditions. It is important for food producers to determine if their food supports the growth of L. monocytogenes. The European Union Reference Laboratory for L. monocytogenes published a Technical Guidance document for conducting shelf-life studies on L. monocytogenes in ready-to-eat foods in June 2014. Primarily based on the EURL guidance document for conducting challenge studies, the ability of cheese (feta and soft goat's milk cheese), cold-smoked salmon, coleslaw, and pork pate to support the growth of L. monocytogenes was determined using a starting inoculum of approximately 100 cfu g-1. The cheese and pork pate were incubated at 8 degrees C for 14 days; the smoked salmon was incubated at 6 degrees C for 5 days and 8 degrees C for 9 days; and the coleslaw was incubated at 8 degrees C for 7 days and 12 degrees C for 14 days. The results showed that the smoked salmon and pork pate supported growth, while coleslaw and cheese did not. From this study, it is evident that there are factors in food other than pH, water activity, and total bacterial count (TBC) that can inhibit the ability of L. monocytogenes to grow in food. PMID- 30301169 TI - Improvement of Soybean Agrobacterium-Mediated Transformation Efficiency by Adding Glutamine and Asparagine into the Culture Media. AB - As a genetically modified crop, transgenic soybean occupies the largest global scale with its food, nutritional, industrial, and pharmaceutical uses.Efficient transformation is a key factor for the improvement of genetically modified soybean. At present, the Agrobacterium-mediated method is primarily used for soybean transformation, but the efficiency of this method is still relatively low (below 5%) compared with rice (above 90%). In this study, we examined the influence of l-glutamine and/or l-asparagine on Agrobacterium-mediated transformation in soybean and explored the probable role in the process of Agrobacterium-mediated transformation. The results showed that when the amino acids l-glutamine and l-asparagine were added separately or together to the culture medium, the shoot induction frequency, elongation rate, and transformation frequency were improved. The combined effects of l-glutamine and l asparagine were better than those of l-glutamine and l-asparagine alone. The 50 mg/L l-glutamine and 50 mg/L l-asparagine together can enhance the transformation frequency of soybean by attenuating the expression level of GmPRs (GmPR1, GmPR4, GmPR5, and GmPR10) and suppression of the plant defense response. The transgene was successfully transmitted to the T1 generation. This study will be useful in genetic engineering of soybean. PMID- 30301170 TI - Erucic Acid (22:1n-9) in Fish Feed, Farmed, and Wild Fish and Seafood Products. AB - The European Food Safety Authority (EFSA) published a risk assessment of erucic acid (22:1n-9) in 2016, establishing a Tolerable Daily Intake (TDI) for humans of 7 mg kg-1 body weight per day. This report largely excluded the contribution of erucic acid from fish and seafood, due to this fatty acid often not being reported separately in seafood. The Institute of Marine Research (IMR) in Norway analyzes erucic acid and has accumulated extensive data from analyses of fish feeds, farmed and wild fish, and seafood products. Our data show that rapeseed oil (low erucic acid varieties) and fish oil are the main sources of erucic acid in feed for farmed fish. Erucic acid content increases with total fat content, both in farmed and wild fish, and it is particularly high in fish liver, fish oil, and oily fish, such as mackerel. We show that the current TDI could be exceeded with a 200 g meal of mackerel, as at the maximum concentration analyzed, such a meal would contribute 143% to the TDI of a 60 kg person. These data cover a current knowledge gap in the scientific literature regarding the content of erucic acid in fish and seafood. PMID- 30301172 TI - A Novel Sampling Method to Measure Socioeconomic Drivers of Aedes Albopictus Distribution in Mecklenburg County, North Carolina. AB - Climate change, urbanization, and globalization have facilitated the spread of Aedes mosquitoes into regions that were previously unsuitable, causing an increased threat of arbovirus transmission on a global scale. While numerous studies have addressed the urban ecology of Ae. albopictus, few have accounted for socioeconomic factors that affect their range in urban regions. Here we introduce an original sampling design for Ae. albopictus, that uses a spatial optimization process to identify urban collection sites based on both geographic parameters as well as the gradient of socioeconomic variables present in Mecklenburg County, North Carolina, encompassing the city of Charlotte, a rapidly growing urban environment. We collected 3,645 specimens of Ae. albopictus (87% of total samples) across 12 weeks at the 90 optimized site locations and modelled the relationships between the abundance of gravid Ae. albopictus and a variety of neighborhood socioeconomic attributes as well as land cover characteristics. Our results demonstrate that the abundance of gravid Ae. albopictus is inversely related to the socioeconomic status of the neighborhood and directly related to both landscape heterogeneity as well as proportions of particular resident races/ethnicities. We present our results alongside a description of our novel sampling scheme and its usefulness as an approach to urban vector epidemiology. Additionally, we supply recommendations for future investigations into the socioeconomic determinants of vector-borne disease risk. PMID- 30301171 TI - Clinical Implications of Hepatitis B Virus RNA and Covalently Closed Circular DNA in Monitoring Patients with Chronic Hepatitis B Today with a Gaze into the Future: The Field Is Unprepared for a Sterilizing Cure. AB - . Chronic hepatitis B virus (HBV) infection has long remained a critical global health issue. Covalently closed circular DNA (cccDNA) is a persistent form of the HBV genome that maintains HBV chronicity. Decades of extensive research resulted in the two therapeutic options currently available: nucleot(s)ide analogs and interferon (IFN) therapy. A plethora of reliable markers to monitor HBV patients has been established, including the recently discovered encapsidated pregenomic RNA in serum, which can be used to determine treatment end-points and to predict the susceptibility of patients to IFN. Additionally, HBV RNA splice variants and cccDNA and its epigenetic modifications are associated with the clinical course and risks of hepatocellular carcinoma (HCC) and liver fibrosis. However, new antivirals, including CRISPR/Cas9, APOBEC-mediated degradation of cccDNA, and T cell therapies aim at completely eliminating HBV, and it is clear that the diagnostic arsenal for defining the long-awaited sterilizing cure is missing. In this review, we discuss the currently available tools for detecting and measuring HBV RNAs and cccDNA, as well as the state-of-the-art in clinical implications of these markers, and debate needs and goals within the context of the sterilizing cure that is soon to come. PMID- 30301173 TI - Photo-Crosslinked Polymeric Matrix with Antimicrobial Functions for Excisional Wound Healing in Mice. AB - Wound infection extends the duration of wound healing and also causes systemic infections such as sepsis, and, in severe cases, may lead to death. Early prevention of wound infection and its appropriate treatment are important. A photoreactive modified gelatin (GE-BTHE) was synthesized by gelatin and a conjugate formed from the 3,3',4,4'-benzophenone tetracarboxylic dianhydride (BTDA) and the 2-hydroxyethyl methacrylate (HEMA). Herein, we investigated the photocurable polymer solution (GE-BTHE mixture) containing GE-BTHE, poly(ethylene glycol) diacrylate (PEGDA), chitosan, and methylene blue (MB), with antimicrobial functions and photodynamic antimicrobial chemotherapy for wound dressing. This photocurable polymer solution was found to have fast film-forming property attributed to the photochemical reaction between GE-BTHE and PEGDA, as well as the antibacterial activity in vitro attributed to the ingredients of chitosan and MB. Our in vivo results also demonstrated that untreated wounds after 3 days had the same scab level as the GE-BTHE mixture-treated wounds after 20 s of irradiation, which indicates that the irradiated GE-BTHE mixture can be quickly transferred into artificial scabs to protect wounds from an infection that can serve as a convenient excisional wound dressing with antibacterial efficacy. Therefore, it has the potential to treat nonhealing wounds, deep burns, diabetic ulcers and a variety of mucosal wounds.

AB - The Hedgehog (HH) signaling pathway plays an important role in embryonic and postnatal vascular development and in maintaining the homeostasis of organs. Under physiological conditions, Sonic Hedgehog (SHH), a secreted protein belonging to the HH family, regulates endothelial cell growth, promotes cell migration and stimulates the formation of new blood vessels. The present review highlights recent advances made in the field of SHH signaling in endothelial progenitor cells (EPCs). The canonical and non-canonical SHH signaling pathways in EPCs and endothelial cells (ECs) related to homeostasis, SHH signal transmission by extracellular vesicles (EVs) or exosomes containing single-strand non-coding miRNAs and impaired SHH signaling in cardiovascular diseases are discussed. As a promising therapeutic tool, the possibility of using the SHH signaling pathway for the activation of EPCs in patients suffering from cardiovascular diseases is further explored. PMID- 30301175 TI - Simultaneous Enhancement of Mechanical and Magnetic Properties in Extremely-Fine Nanograined Ni-P Alloys. AB - Exploring structural effects that influence both the mechanics and magnetism in nanocrystalline materials, particularly extremely-fine nanograined ones with grain sizes down to several nanometers, is of high interest for developing multifunctional materials combining superior mechanical and magnetic performances. We found in this work that electrodeposited extremely-fine nanograined Ni-P alloys exhibit a significant enhancement of magnetization, simultaneously along with an increase in hardness, after low-temperature annealing. The relaxation of non-equilibrium structures, precipitation of the second phase and the segregation of P atoms to grain boundaries (GBs) during annealing have then been sequentially evidenced. By systematically comparing the variations in macroscopic and microstructural investigation results among several Ni-P alloys with different P contents, we suggest that the second phase has little effect on magnetization enhancement, and essentially both the structural relaxation and GB segregation can play important roles in hardening by governing GB stability, and in the improvement of magnetization by enhancing Ni-Ni atom exchange interactions.

AB - Fifty-seven compounds were purified from the stems of Tinospora sinensis, including three new compounds characterized as a lignan (1), a pyrrole alkaloid (11), and a benzenoid (17), respectively. Their structures were elucidated and established by various spectroscopic and spectrometric analytical methods. Among the isolates, fifteen compounds were examined for their anti-inflammatory potential in vitro. The results showed that several compounds displayed moderate inhibition of N-formyl-methionyl-leucyl-phenylalanine/cytochalasin B (fMLP/CB) induced superoxide anion generation and elastase release. PMID- 30301177 TI - Modern Compact Cities: How Much Greenery Do We Need? AB - The modern compact city is identified as a high-density and mixed-use pattern. Its features are believed to contribute to a form of functional urban design that supports sustainability and, restresses, the importance of ecosystem services. Urban green space (UGS) plays a vital role in the design and impact on how compact cities have developed and triggered a scientific discord on the amount of greenery individuals require and to what extent contemporary approaches address the question. Research points to at least 9 m2 of green space per individual with an ideal UGS value of 50 m2 per capita. An examination on the perception, use, quality, accessibility and health risks of urban green and blue spaces is explored, alongside the availability of novel UGS and greenery-related approaches that investigate compact city design and planning for health and wellbeing. The amount of 'green' and relating UGS availability in cities indicates vital knowledge modern compact cities must consider. PMID- 30301178 TI - Degassing Rhythms and Fluctuations of Geogenic Gases in A Red Wood-Ant Nest and in Soil in The Neuwied Basin (East Eifel Volcanic Field, Germany). AB - Geochemical tracers of crustal fluids (CO2, He, Rn) provide a useful tool for the identification of buried fault structures. We acquired geochemical data during 7 months of continual sampling to identify causal processes underlying correlations between ambient air and degassing patterns of three gases (CO2, He, Rn) in a nest of red wood ants (Formica polyctena; "RWA") and the soil at Goloring in the Neuwied Basin, a part of the East Eifel Volcanic Field (EEVF). We explored whether temporal relations and degassing rhythms in soil and nest gas concentrations could be indicators of hidden faults through which the gases migrate to the surface from depth. In nest gas, the coupled system of CO2-He and He concentrations exceeding atmospheric standards 2-3 fold suggested that RWA nests may be biological indicators of hidden degassing faults and fractures at small scales. Equivalently periodic degassing infradian rhythms in the RWA nest, soil, and three nearby minerals springs suggested NW-SE and NE-SW tectonic linkages. Because volcanic activity in the EEVF is dormant, more detailed information on the EEVF's tectonic, magmatic, and degassing systems and its active tectonic fault zones are needed. Such data could provide additional insights into earthquake processes that are related to magmatic processes at the lower crust. PMID- 30301179 TI - Identifying Risk of Viral Failure in Treated HIV-Infected Patients Using Different Measures of Adherence: The Antiretroviral Therapy Cohort Collaboration. AB - Adherence to antiretroviral therapy (ART) is critical for successful treatment of Human Immunodeficiency Virus (HIV), but comparisons across settings are difficult because adherence is measured in different ways. We examined utility of different adherence measures for identification of patients at risk of viral failure (VF). Eight cohorts in the ART Cohort Collaboration contributed data from pharmacy refills or self-report questionnaires collected between 1996 and 2013 (N = 11689). For pharmacy data (N = 7156), we examined associations of percentage adherence during the 1st year of ART with VF (>500 copies/mL) at 1 year. For self report data (N = 4533), we examined 28-day adherence with VF based on closest viral load measure within 6 months after questionnaire date. Since adherence differed markedly by measurement type, we defined different cut-off points for pharmacy (lower <45%, medium 45-99%, higher 100%) and self-report (lower <=95%, medium 96-99%, higher 100%) data. Adjusted odds ratios (ORs) for VF in lower and medium, compared to higher adherence groups, were 23.04 (95% CI: 18.44-28.78) and 3.84 (3.36-4.39) for pharmacy data. For self-report data, they were 3.19 (2.31 4.40) and 1.08 (0.80-1.46). Both types of measure were strongly associated with VF. Although adherence measurements over longer time-frames are preferable for prediction, they are less useful for intervention. PMID- 30301180 TI - Antibacterial and Antibiofilm Activity and Mode of Action of Magainin 2 against Drug-Resistant Acinetobacter baumannii. AB - Antimicrobial peptides (AMPs) are promising therapeutic agents for treating antibiotic-resistant bacterial infections. Previous studies showed that magainin 2 (isolated from African clawed fogs Xenopus laevis) has antimicrobial activity against gram-positive and gram-negative bacteria. The present study was conducted to investigate the antibacterial activity of magainin 2 against Acinetobacter baumannii. Magainin 2 showed excellent antibacterial activity against A. baumannii strains and high stability at physiological salt concentrations. This peptide was not cytotoxic towards HaCaT cells and showed no hemolytic activity. Biofilm inhibition and elimination were significantly induced in all A. baumannii strains exposed to magainin 2. We confirmed the mechanism of magainin 2 on the bacterial outer and inner membranes. Collectively, these results suggest that magainin 2 is an effective antimicrobial and antibiofilm agent against A. baumannii strains. PMID- 30301181 TI - Enhanced Gas-Sensing Performance of GO/TiO2 Composite by Photocatalysis. AB - Few studies have investigated the gas-sensing properties of graphene oxide/titanium dioxide (GO/TiO2) composite combined with photocatalytic effect. Room temperature gas-sensing properties of the GO/TiO2 composite were investigated towards various reducing gases. The composite sensor showed an enhanced gas response and a faster recovery time than a pure GO sensor due to the synergistic effect of the hybridization, such as creation of a hetero-junction at the interface and modulation of charge carrier density. However, the issue of long-term stability at room temperature still remains unsolved even after construction of a composite structure. To address this issue, the surface and hetero-junction of the GO/TiO2 composite were engineered via a UV process. A photocatalytic effect of TiO2 induced the reduction of the GO phase in the composite solution. The comparison of gas-sensing properties before and after the UV process clearly showed the transition from n-type to p-type gas-sensing behavior toward reducing gases. This transition revealed that the dominant sensing material is GO, and TiO2 enhanced the gas reaction by providing more reactive sites. With a UV-treated composite sensor, the function of identifying target gas was maintained over a one-month period, showing strong resistance to humidity.

Part I: Synthesis and Evaluation of Substance P Fragments Labeled with 99mTc and 177Lu as Potential Receptor Radiopharmaceuticals. AB - Gliomas, particularly WHO grade IV glioblastoma multiforme, are one of the most common and aggressive primary tumors of the central nervous system. The neuropeptide, substance P (SP), is the physiological ligand of the neurokinin-1 (NK-1) receptor that is consistently overexpressed in glioblastoma cells. The aim of this work was to study physico-chemical and biological properties of different SP analogues labeled with technetium-99m and lutetium-177 radionuclides. The synthesized compounds were characterized in vitro by partition coefficients (logP) and their stability was investigated in various physiological solutions. Biological properties (Kd, Bmax) were characterized using the U373 MG cell line. The obtained lipophilicity values of the [99mTc]NS3/CN-SP and [177Lu]DOTA-SP radiobioconjugates were in the range of -0.3 to +0.6 and -2.5 to -5.0, respectively. The studied radiobioconjugates were stable in PBS buffer and CSF, as well as in 10 mM histidine and/or cysteine solutions whereas in human serum showed enzymatic biodegradation. [177Lu]DOTA-[Thi8,Met(O2)11]SP(1-11), [177Lu]DOTA-SP(4-11) and [177Lu]DOTA-[Thi8,Met(O2)11]SP(5-11) radiobioconjugates bound specifically to NK-1 receptors expressed on glioblastoma cells with affinity in the nanomolar range. To conclude, the shorter analogues of SP can be used as vectors, nevertheless they still do not fulfil all requirements for preparations in nuclear medicine. PMID- 30301183 TI - Nanostructured TiO2 Carbon Paste Based Sensor for Determination of Methyldopa. AB - Methyldopa is a catecholamine widely used in the treatment of mild to moderate hypertension whose determination in pharmaceutical formulae is of upmost importance for dose precision. Henceforth, a low-cost carbon paste electrode (CPE) consisting of graphite powder obtained from a crushed pencil stick was herein modified with nanostructured TiO2 (TiO2@CPE) aiming for the detection of methyldopa in pharmaceutical samples. The TiO2-modified graphite powder was characterized by scanning electron microscopy and X-ray diffraction, which demonstrated the oxide nanostructured morphology. Results evidenced that sensitivity was nonetheless increased due to electro-catalytic effects promoted by metal modification, and linear response obtained by differential pulse voltammetry for the determination of methyldopa (pH = 5.0) was between 10-180 MUmol/L (Limit of Detection = 1 MUmol/L) with the TiO2@CPE sensor. Furthermore, the constructed sensor was successfully applied in the detection of methyldopa in pharmaceutical formulations and excipients promoted no interference, that indicates that the sensor herein developed is a cheap, reliable, and useful strategy to detect methyldopa in pharmaceutical samples, and may also be applicable in determinations of similar compounds. PMID- 30301184 TI - The Significance of Low Titre Antigliadin Antibodies in the Diagnosis of Gluten Ataxia. AB - BACKGROUND: Patients with gluten ataxia (GA) without enteropathy have lower levels of antigliadin antibodies (AGA) compared to patients with coeliac disease (CD). Magnetic Resonance Spectroscopy (NAA/Cr area ratio) of the cerebellum improves in patients with GA following a strict gluten-free diet (GFD). This is associated with clinical improvement. We present our experience of the effect of a GFD in patients with ataxia and low levels of AGA antibodies measured by a commercial assay. METHODS: Consecutive patients with ataxia and serum AGA levels below the positive cut-off for CD but above a re-defined cut-off in the context of GA underwent MR spectroscopy at baseline and after a GFD. RESULTS: Twenty-one consecutive patients with GA were included. Ten were on a strict GFD with elimination of AGA, 5 were on a GFD but continued to have AGA, and 6 patients did not go on a GFD. The NAA/Cr area ratio from the cerebellar vermis increased in all patients on a strict GFD, increased in only 1 out of 5 (20%) patients on a GFD with persisting circulating AGA, and decreased in all patients not on a GFD. CONCLUSION: Patients with ataxia and low titres of AGA benefit from a strict GFD. The results suggest an urgent need to redefine the serological cut-off for circulating AGA in diagnosing GA. PMID- 30301185 TI - Role of Milk-Derived Antibacterial Peptides in Modern Food Biotechnology: Their Synthesis, Applications and Future Perspectives. AB - Milk-derived antibacterial peptides (ABPs) are protein fragments with a positive influence on the functions and conditions of a living organism. Milk-derived ABPs have several useful properties important for human health, comprising a significant antibacterial effect against various pathogens, but contain toxic side-effects. These compounds are mainly produced from milk proteins via fermentation and protein hydrolysis. However, they can also be produced using recombinant DNA techniques or organic synthesis. This review describes the role of milk-derived ABPs in modern food biotechnology with an emphasis on their synthesis and applications. Additionally, we also discuss the mechanisms of action and the main bioproperties of ABPs. Finally, we explore future perspectives for improving ABP physicochemical properties and diminishing their toxic side-effects. PMID- 30301186 TI - Design of an Aluminum/Polymer Plasmonic 2D Crystal for Label-Free Optical Biosensing. AB - A design study of a nanostructured two-dimensional plasmonic crystal based on aluminum and polymeric material for label-free optical biosensing is presented. The structure is formed of Al nanohole and nanodisk array layers physically separated by a polymeric film. The photonic configuration was analyzed through finite-difference time-domain (FDTD) simulations. The calculated spectral reflectance of the device exhibits a surface plasmon polariton (SPP) resonance feature sensitive to the presence of a modeled biolayer adhered onto the metal surfaces. Simulations also reveal that the Al disks suppress an undesired SPP resonance, improving the device performance in terms of resolution as compared to that of a similar configuration without Al disks. On the basis of manufacturability issues, nanohole diameter and depth were considered as design parameters, and a multi-objective optimization process was employed to determine the optimum dimensional values from both performance and fabrication points of view. The effect of Al oxidation, which is expected to occur in an actual device, was also studied. PMID- 30301187 TI - Audencel Immunotherapy Based on Dendritic Cells Has No Effect on Overall and Progression-Free Survival in Newly Diagnosed Glioblastoma: A Phase II Randomized Trial. AB - Dendritic cells (DCs) are antigen-presenting cells that are capable of priming anti-tumor immune responses, thus serving as attractive tools to generate tumor vaccines. In this multicentric randomized open-label phase II study, we investigated the efficacy of vaccination with tumor lysate-charged autologous DCs (Audencel) in newly diagnosed glioblastoma multiforme (GBM). Patients aged 18 to 70 years with histologically proven primary GBM and resection of at least 70% were randomized 1:1 to standard of care (SOC) or SOC plus vaccination (weekly intranodal application in weeks seven to 10, followed by monthly intervals). The primary endpoint was progression-free survival at 12 months. Secondary endpoints were overall survival, safety, and toxicity. Seventy-six adult patients were analyzed in this study. Vaccinations were given for seven (3-20) months on average. No severe toxicity was attributable to vaccination. Seven patients showed flu-like symptoms, and six patients developed local skin reactions. Progression-free survival at 12 months did not differ significantly between the control and vaccine groups (28.4% versus 24.5%, p = 0.9975). Median overall survival was similar with 18.3 months (vaccine: 564 days, 95% CI: 436-671 versus control: 568 days, 95% CI: 349-680; p = 0.89, harzard ratio (HR) 0.99). Hence, in this trial, the clinical outcomes of patients with primary GBM could not be improved by the addition of Audencel to SOC. PMID- 30301188 TI - Effect of Resveratrol on Reactive Oxygen Species-Induced Cognitive Impairment in Rats with Angiotensin II-Induced Early Alzheimer's Disease ?. AB - Recent studies have indicated that several anti-hypertensive drugs may delay the development and progression of Alzheimer's disease (AD). However, the relationships among AD, hypertension, and oxidative stress remain to be elucidated. Here, we aimed to determine whether reactive oxygen species (ROS) reduction by resveratrol in the brain leads to cognitive impairment reduction in rats with angiotensin II (Ang-II)-induced early AD. Male Wistar Kyoto (WKY) rats with Ang-II-induced AD were treated with losartan or resveratrol for two weeks. Our results show decreased blood pressure, increased hippocampal brain-derived neurotrophic factor (BDNF) level, and decreased nucleus tractus solitarius (NTS) ROS production in the Ang-II groups with losartan (10 mg/kg), or resveratrol (10 mg/kg/day) treatment. Furthermore, losartan inhibition of hippocampal TauT231 phosphorylation activated AktS473 phosphorylation, and significantly abolished Ang-II-induced Abeta precursors, active caspase 3, and glycogen synthase kinase 3beta (GSK-3beta)Y216 expressions. Consistently, resveratrol showed similar effects compared to losartan. Both losartan and resveratrol restored hippocampal dependent contextual memory by NADPH oxidase 2 (NOX2) deletion and superoxide dismutase 2 (SOD2) elevation. Our results suggest that both losartan and resveratrol exert neuroprotective effects against memory impairment and hippocampal damage by oxidative stress reduction in early stage AD rat model. These novel findings indicate that resveratrol may represent a pharmacological option similar to losartan for patients with hypertension at risk of AD during old age.

AB - As one of the major abiotic stresses, salinity stress may affect the physiology and biochemical components of Apocynum venetum L. To systematically evaluate the quality of Apocyni Veneti Folium (AVF) from the perspective of physiological and the wide variety of bioactive components response to various concentrations of salt stress, this experiment was arranged on the basis of ultra-fast liquid chromatography tandem triple quadrupole mass spectrometry (UFLC-QTRAP-MS/MS) technology and multivariate statistical analysis. Physiological characteristics of photosynthetic pigments, osmotic homeostasis, lipid peroxidation product, and antioxidative enzymes were introduced to investigate the salt tolerance mechanism of AVF under salinity treatments of four concentrations (0, 100, 200, and 300 mM NaCl, respectively). Furthermore, a total of 43 bioactive constituents, including 14 amino acids, nine nucleosides, six organic acids, and 14 flavonoids were quantified in AVF under salt stress. In addition, multivariate statistical analysis, including hierarchical clustering analysis, principal component analysis (PCA), and gray relational analysis (GRA) was employed to systematically cluster, distinguish, and evaluate the samples, respectively. Compared with the control, the results demonstrated that 200 mM and 100 mM salt stress contributed to maintain high quality of photosynthesis, osmotic balance, antioxidant enzyme activity, and the accumulation of metabolites, except for total organic acids, and the quality of AVF obtained by these two groups was better than others; however, under severe stress, the accumulation of the oxidative damage and the reduction of metabolite caused by inefficiently scavenging reactive oxygen species (ROS) lead to lower quality. In summary, the proposed method may provide integrated information for the quality evaluation of AVF and other salt-tolerant Chinese medicines. PMID- 30301189 TI - Genome-Wide Investigation of Genes Regulated by ERalpha in Breast Cancer Cells. AB - Estrogen receptor alpha (ERalpha), which has been detected in over 70% of breast cancer cases, is a driving factor for breast cancer growth. For investigating the underlying genes and networks regulated by ERalpha in breast cancer, RNA-seq was performed between ERalpha transgenic MDA-MB-231 cells and wild type MDA-MB-231 cells. A total of 267 differentially expressed genes (DEGs) were identified. Then bioinformatics analyses were performed to illustrate the mechanism of ERalpha. Besides, by comparison of RNA-seq data obtained from MDA-MB-231 cells and microarray dataset obtained from estrogen (E2) stimulated MCF-7 cells, an overlap of 126 DEGs was screened. The expression level of ERalpha was negatively associated with metastasis and EMT in breast cancer. We further verified that ERalpha might inhibit metastasis by regulating of VCL and TNFRSF12A, and suppress EMT by the regulating of JUNB and ID3. And the relationship between ERalpha and these genes were validated by RT-PCR and correlation analysis based on TCGA database. By PPI network analysis, we identified TOP5 hub genes, FOS, SP1, CDKN1A, CALCR and JUNB, which were involved in cell proliferation and invasion. Taken together, the whole-genome insights carried in this work can help fully understanding biological roles of ERalpha in breast cancer. PMID- 30301192 TI - A Robotic Context Query-Processing Framework Based on Spatio-Temporal Context Ontology. AB - Service robots operating in indoor environments should recognize dynamic changes from sensors, such as RGB-depth (RGB-D) cameras, and recall the past context. Therefore, we propose a context query-processing framework, comprising spatio temporal robotic context query language (ST-RCQL) and a spatio-temporal robotic context query-processing system (ST-RCQP), for service robots. We designed them based on spatio-temporal context ontology. ST-RCQL can query not only the current context knowledge, but also the past. In addition, ST-RCQL includes a variety of time operators and time constants; thus, queries can be written very efficiently. The ST-RCQP is a query-processing system equipped with a perception handler, working memory, and backward reasoner for real-time query-processing. Moreover, ST-RCQP accelerates query-processing speed by building a spatio-temporal index in the working memory, where percepts are stored. Through various qualitative and quantitative experiments, we demonstrate the high efficiency and performance of the proposed context query-processing framework. PMID- 30301191 TI - Secondary Unconjugated Bile Acids Induce Hepatic Stellate Cell Activation. AB - Hepatic stellate cells (HSCs) are key players in liver fibrosis, cellular senescence, and hepatic carcinogenesis. Bile acids (BAs) are involved in the activation of HSCs, but the detailed mechanism of this process remains unclear. We conducted a comprehensive DNA microarray study of the human HSC line LX-2 treated with deoxycholic acid (DCA), a secondary unconjugated BA. Additionally, LX-2 cells were exposed to nine BAs and studied using immunofluorescence staining, enzyme-linked immunosorbent assay, and flow cytometry to examine the mechanisms of HSC activation. We focused on the tumor necrosis factor (TNF) pathway and revealed upregulation of genes related to nuclear factor kappa B (NF kappaB) signaling and senescence-associated secretory phenotype factors. alpha Smooth muscle actin (alpha-SMA) was highly expressed in cells treated with secondary unconjugated BAs, including DCA, and a morphological change associated with radial extension of subendothelial protrusion was observed. Interleukin-6 level in culture supernatant was significantly higher in cells treated with secondary unconjugated BAs. Flow cytometry showed that the proportion of cells highly expressing alpha-SMA was significantly increased in HSCs cultured with secondary unconjugated BAs. We demonstrated that secondary unconjugated BAs induced the activation of human HSCs. PMID- 30301193 TI - Efficient Encapsulation of Citral in Fast-Dissolving Polymer-Free Electrospun Nanofibers of Cyclodextrin Inclusion Complexes: High Thermal Stability, Longer Shelf-Life, and Enhanced Water Solubility of Citral. AB - Here, we report a facile production of citral/cyclodextrin (CD) inclusion complex (IC) nanofibers (NFs) from three types of CDs (hydroxypropyl-beta-cyclodextrin (HPbetaCD), hydroxypropyl-gamma-cyclodextrin (HPgammaCD), and methylated-beta cyclodextrin (MbetaCD)) by an electrospinning technique without the need of any polymeric carrier matrix. Self-standing nanofibrous webs of citral/CD-IC nanofibers (citral/CD-IC-NF) with uniform fiber morphology have been successfully electrospun from aqueous solutions of citral/CD-IC. Thanks to the inclusion complex formed with CDs, the efficient preservation of citral (up to ~80%) in citral/CD-IC-NFs was observed. In addition, the citral/CD-IC-NFs have shown ~50% preservation of citral for 15 days at room temperature even though citral has a highly volatile nature. The enhanced thermal stability of citral (~100-300 degrees C) in citral/CD-IC-NFs compared to pure citral (~50-165 degrees C) has been observed. Moreover, citral/CD-IC-NFs tended to disintegrate in water very quickly. To summarize, citral was efficiently encapsulated in citral/CD-IC-NFs, and these citral/CD-IC-NFs have been shown to be fast dissolving. In citral/CD-IC NFs, citral/CD-ICs have enhanced water solubility of citral along with high temperature stability and a longer shelf-life. PMID- 30301196 TI - SECOND: Sparsely Embedded Convolutional Detection. AB - LiDAR-based or RGB-D-based object detection is used in numerous applications, ranging from autonomous driving to robot vision. Voxel-based 3D convolutional networks have been used for some time to enhance the retention of information when processing point cloud LiDAR data. However, problems remain, including a slow inference speed and low orientation estimation performance. We therefore investigate an improved sparse convolution method for such networks, which significantly increases the speed of both training and inference. We also introduce a new form of angle loss regression to improve the orientation estimation performance and a new data augmentation approach that can enhance the convergence speed and performance. The proposed network produces state-of-the-art results on the KITTI 3D object detection benchmarks while maintaining a fast inference speed. PMID- 30301194 TI - Headache Associated with Coeliac Disease: A Systematic Review and Meta-Analysis. AB - OBJECTIVE: The aim of this systematic review was to explore the relationship between coeliac disease (CD) and headache. The objectives were to establish the prevalence of each entity amongst the other, to explore the role of gluten free diet (GFD), and to describe the imaging findings in those affected by headaches associated with CD. METHODOLOGY: A systematic computer-based literature search was conducted on the PubMed database. Information regarding study type, population size, the age group included, prevalence of CD amongst those with headache and vice versa, imaging results, the nature of headache, and response to GFD. RESULTS: In total, 40 articles published between 1987 and 2017 qualified for inclusion in this review. The mean pooled prevalence of headache amongst those with CD was 26% (95% CI 19.5-33.9%) in adult populations and 18.3% (95% CI 10.4 30.2%) in paediatric populations. The headaches are most often migraine-like. In children with idiopathic headache, the prevalence of CD is 2.4% (95% CI 1.5 3.7%), whereas data for adult populations is presently unavailable. Brain imaging can be normal, although, cerebral calcifications on CT, white matter abnormalities on MRI and deranged regional cerebral blood flow on SPECT can be present. GFD appears to be an effective management for headache in the context of CD, leading to total resolution of headaches in up to 75% of patients. CONCLUSIONS: There is an increased prevalence of CD amongst idiopathic headache and vice versa. Therefore, patients with headache of unknown origin should be screened for CD, as such patients may symptomatically benefit from a GFD. PMID- 30301195 TI - Do the Effects of Resveratrol on Thermogenic and Oxidative Capacities in IBAT and Skeletal Muscle Depend on Feeding Conditions? AB - The aim of this study was to compare the effects of mild energy restriction and resveratrol on thermogenic and oxidative capacity in interscapular brown adipose tissue (IBAT) and in skeletal muscle. Rats were fed a high-fat high-sucrose diet for six weeks, and divided into four experimental groups fed a standard diet: a control group, a resveratrol-treated group, an energy-restricted group and an energy-restricted group treated with resveratrol. Weights of IBAT, gastrocnemius muscle and fat depots were measured. Activities of carnitine palmitoyltransferase (CPT) and citrate synthase (CS), protein levels of sirtuin (SIRT1 and 3), uncoupling proteins (UCP1 and 3), glucose transporter (GLUT4), mitochondrial transcription factor (TFAM), nuclear respiratory factor (NRF1), peroxisome proliferator-activated receptor (PPARalpha) and AMP activated protein kinase (AMPK) and peroxisome proliferator-activated receptor gamma coactivator (PGC1alpha) activation were measured. No changes in IBAT and gastrocnemius weights were found. Energy-restriction, but not resveratrol, decreased the weights of adipose depots. In IBAT, resveratrol enhanced thermogenesis activating the SIRT1/PGC1alpha/PPARalpha axis. Resveratrol also induced fatty acid oxidation and glucose uptake. These effects were similar when resveratrol was combined with energy restriction. In the case of gastrocnemius muscle, the effects were not as clear as in the case of IBAT. In this tissue, resveratrol increased oxidative capacity. The combination of resveratrol and energy restriction seemingly did not improve the effects induced by the polyphenol alone. PMID- 30301197 TI - Further Evidence on Efficacy of Diet Supplementation with Fatty Acids in Ocular Pathologies: Insights from the EAE Model of Optic Neuritis. AB - In the experimental autoimmune encephalomyelitis (EAE) mouse model of optic neuritis, we recently demonstrated that diet supplementation with a balanced mixture of fatty acids (FAs), including omega 3 and omega 6, efficiently limited inflammatory events in the retina and prevented retinal ganglion cell (RGC) death, although mechanisms underlying the efficacy of FAs were to be elucidated. Whether FAs effectiveness was accompanied by efficient rescue of demyelinating events in the optic nerve was also unresolved. Finally, the possibility that RGC rescue might result in ameliorated visual performance remained to be investigated. Here, the EAE model of optic neuritis was used to investigate mechanisms underlying the anti-inflammatory effects of FAs, including their potential efficacy on macrophage polarization. In addition, we determined how FAs induced rescue of RGC degeneration was related to optic nerve histopathology by performing ultrastructural morphometric analysis with transmission electron microscopy. Finally, RGC rescue was correlated with visual performance by recording photopic electroretinogram, an efficient methodology to unravel the role of RGCs in the generation of electroretinographic waves. We conclude that the ameliorative effects of FAs were dependent on a predominant anti-inflammatory action including a role on promoting the shift of macrophages from the inflammatory M1 phenotype towards the anti-inflammatory M2 phenotype. This would finally result in restored optic nerve histopathology and ameliorated visual performance. These findings can now offer new perspectives for implementing our knowledge on the effectiveness of diet supplementation in counteracting optic neuritis and suggest the importance of FAs as possible adjuvants in therapies against inflammatory diseases of the eye. PMID- 30301199 TI - Direct Depth SLAM: Sparse Geometric Feature Enhanced Direct Depth SLAM System for Low-Texture Environments. AB - This paper presents a real-time, robust and low-drift depth-only SLAM (simultaneous localization and mapping) method for depth cameras by utilizing both dense range flow and sparse geometry features from sequential depth images. The proposed method is mainly composed of three optimization layers, namely Direct Depth layer, ICP (iterative closet point) Refined layer and Graph Optimization layer. The Direct Depth layer uses a range flow constraint equation to solve the fast 6-DOF (six degrees of freedom) frame-to-frame pose estimation problem. Then, the ICP Refined layer is used to reduce the local drift by applying local map based motion estimation strategy. After that, we propose a loop closure detection algorithm by extracting and matching sparse geometric features and construct a pose graph for the purpose of global pose optimization. We evaluate the performance of our method using benchmark datasets and real scene data. Experiment results show that our front-end algorithm clearly over performs the classic methods and our back-end algorithm is robust to find loop closures and reduce the global drift.

AB - Inflammatory bowel diseases are a set of complex and debilitating diseases, for which there is no satisfactory treatment. Peptides as small as three amino acids have been shown to have anti-inflammatory activity in mouse models of colitis, but they are likely to be unstable, limiting their development as drug leads. Here, we have grafted a tripeptide from the annexin A1 protein into linaclotide, a 14-amino-acid peptide with three disulfide bonds, which is currently in clinical use for patients with chronic constipation or irritable bowel syndrome. This engineered disulfide-rich peptide maintained the overall fold of the original synthetic guanylate cyclase C agonist peptide, and reduced inflammation in a mouse model of acute colitis. This is the first study to show that this disulfide-rich peptide can be used as a scaffold to confer a new bioactivity. PMID- 30301198 TI - Can Nuts Mitigate Malnutrition in Older Adults? A Conceptual Framework. AB - The proportion of adults aged over 60 years in the world is expected to reach 20% by the year 2050. Ageing is associated with several physiological changes that increase the risk of malnutrition among this population. Malnutrition is characterized by deficiencies or insufficiencies of macro- and micronutrients. Malnutrition has detrimental effects on the health, wellbeing, and quality of life in older adults. Nuts are rich in energy, unsaturated fats, and protein, as well as other nutrients that provide a range of health benefits. While the effects of nuts on overnutrition have been studied extensively, very few studies have been specifically designed to understand the role of nuts in mitigating undernutrition in the elderly. Therefore, this review explores the potential role of nuts in improving the nutritional status of older adults who are at risk of undernutrition. Several properties of whole nuts, some of which appear important for addressing overnutrition, (e.g., hardness, lower-than-expected nutrient availability, satiety-enhancing effects) may limit their effectiveness as a food to combat undernutrition. However, we propose that modifications such as transforming the physical form of nuts, addressing the timing of nut ingestion, and introducing variety may overcome these barriers. This review also discusses the feasibility of using nuts to prevent and reverse undernutrition among older adults. We conclude with a recommendation to conduct clinical studies in the future to test this conceptual framework.

AB - High-voltage n-channel lateral-diffused metal-oxide-semiconductor field-effect transistor (nLDMOS) components, fabricated by a TSMC 0.25-m 60-V bipolar-CMOS DMOS (BCD) process with drain-side embedded silicon-controlled rectifier (SCR) of the n-p-n-arranged and p-n-p-arranged types, were investigated, in order to determine the devices' electrostatic discharge (ESD)-sensing behavior and capability by discrete anode engineering. As for the drain-side n-p-n-arranged type with discrete-anode manners, transmission-line-pulse (TLP) testing results showed that the ESD ability (It2 value) was slightly upgraded. When the discrete physical parameter was 91 rows, the optimal It2 reached 2.157 A (increasing 17.7% compared with the reference sample). On the other hand, the drain-side SCR p-n-p arranged type with discrete-anode manner had excellent SCR behavior, and its It2 values could be increased to >7 A (increasing >281.9% compared with the reference DUT). Moreover, under discrete anode engineering, the drain-side SCR n-p-n arranged and p-n-p-arranged types had clearly higher ESD ability, except for the few discrete physical parameters. Therefore, using the anode discrete engineering, the ESD dissipation ability of a high-voltage (HV) nLDMOS with drain side SCRs will have greater effectiveness. PMID- 30301203 TI - Exploring Morphine-Triggered PKC-Targets and Their Interaction with Signaling Pathways Leading to Pain via TrkA. AB - It is well accepted that treatment of chronic pain with morphine leads to MU opioid receptor (MOR) desensitization and the development of morphine tolerance. MOR activation by the selective peptide agonist, D-Ala2, N-MePhe4, Gly-ol] enkephalin(DAMGO), leads to robust G protein receptor kinase activation, beta arrestin recruitment, and subsequent receptor endocytosis, which does not occur in an activation by morphine. However, MOR activation by morphine induces receptor desensitization, in a Protein kinase C (PKC) dependent manner. PKC inhibitors have been reported to decrease receptor desensitization, reduce opiate tolerance, and increase analgesia. However, the exact role of PKC in these processes is not clearly delineated. The difficulties in establishing a particular role for PKC have been, in part, due to the lack of reagents that allow the selective identification of PKC targets. Recently, we generated a conformation state-specific anti-PKC antibody that preferentially recognizes the active state of this kinase. Using this antibody to selectively isolate PKC substrates and a proteomics strategy to establish the identity of the proteins, we examined the effect of morphine treatment on the PKC targets. We found an enhanced interaction of a number of proteins with active PKC, in the presence of morphine. In this article, we discuss the role of these proteins in PKC-mediated MOR desensitization and analgesia. In addition, we posit a role for some of these proteins in mediating pain by TrKA activation, via the activation of transient receptor potential cation channel subfamily V member 1 (TRPV1). Finally, we discuss how these new PKC interacting proteins and pathways could be targeted for the treatment of pain. PMID- 30301201 TI - Epidemiology and Elimination of HCV-Related Liver Disease. AB - Hepatitis C virus (HCV) infection, defined by active carriage of HCV RNA, affects nearly 1.0% of the worldwide population. The main risk factors include unsafe injection drug use and iatrogenic infections. Chronic HCV infection can promote liver damage, cirrhosis and hepatocellular carcinoma (HCC) in affected individuals. The advent of new second-generation, direct-acting antiviral (DAA) agents allow a virological cure in more than 90% of treated patients, and therefore prevent HCV-related complications. Recently, concerns have been raised regarding the safety of DAA-regimens in cirrhotic patients with respect to the occurrence and the recurrence of HCC. Here, we review the current available data on HCV epidemiology, the beneficial effects of therapy, and discuss the recent controversy with respect to the potential link with liver cancer. We also highlight the challenges that have to be overcome to achieve the ambitious World Health Organization objective of HCV eradication by 2030.

AB - The medicinal ferns of Polydiaceae and Davalliaceae species are called "Gusuibu" by Chinese physicians and used as antiaging dietary medicines. Our previous report revealed that Drynaria fortunei (Polydiaceae) protected against 6 hydroxydopamine (6-OHDA)-induced oxidative damage via the PI3K/AKT pathway in B35 neuroblastoma cells. The present study compares the antioxidant phytoconstituent contents and radical scavenging capacities of five Davalliaceae species. The further aim was to clarify the protective mechanism of Davallia mariesii (DM) against 6-OHDA-induced oxidative damage and apoptosis in B35 cells. The results show that Araiostegia perdurans (AP) and DM extracts have better radical scavenging capacities against 1,1-diphenyl-2-picryhydrazyl (DPPH) and reactive oxygen species (ROS) than other Davalliaceae species. However, only DM extract inhibited 6-OHDA autoxidation under cell-free systems and increased cell viability, compared to B35 cells solely exposed to 6-OHDA. DM extract decreased apoptosis and restored mitochondrial expression in 6-OHDA-treated B35 cells. Additional data indicated that DM extract decreased intracellular ROS and nitric oxide levels generated by 6-OHDA exposure. DM extract also restored glutathione (GSH) levels and the activities of glutathione peroxidase and reductase, and then decreased the elevated malondialdehyde (MDA) levels. Finally, DM extract regulated the protein expression of the caspase cascade and PI3K/AKT/GSK-3beta pathways. These results suggest that the protective mechanism of DM extract against 6-OHDA-induced oxidative damage and apoptosis might be related to its radical scavenging capacity, maintaining the mitochondrial function to inhibit the Bcl-2/caspase cascade pathway and activating intracellular antioxidant defenses (GSH recycling, HO-1 and NQO-1) by modulating the activation of the PI3K/AKT/GSK-3beta pathway. PMID- 30301206 TI - Effects of Low Pressure Treatment on the Mortality of Different Life Stages of Indianmeal moth (Plodia interpunctella) and the Quality of Dried Chinese Jujube. AB - Low pressure technology is a potential non-chemical method to control insects in agriculture products. The purpose of this study was to determine the tolerance of different life stages of indianmeal moth (Plodia interpunctella) to low pressure and to validate the mortality of P. interpunctella when infesting Chinese jujube (Zizyphus jujuba Miller) using a low pressure system. Results showed that larvae were the most tolerant life stage of P. interpunctella, with a minimum exposure time of 41.4 h at 1.3 kPa and 25 degrees C to obtain 100% mortality. Pupae were the most susceptible life stage, with a lethal time of 12 h under the above low pressure conditions. The survival ratio of P. interpunctella in jujube decreased with increasing exposure time and reached 0% when the jujubes with P. interpunctella larvae were exposed to low-pressure treatment for 41.6 h at 1.3 kPa and 25 degrees C. Although the color, moisture, soluble solid, and vitamin C contents were slightly changed, there was no significant quality difference in these factors between control and treated jujubes. The information provided by this study is useful in developing effective non-chemical low-pressure treatments for disinfesting agricultural products. PMID- 30301205 TI - Intestinal Saturated Long-Chain Fatty Acid, Glucose and Fructose Transporters and Their Inhibition by Natural Plant Extracts in Caco-2 Cells. AB - The intestinal absorption of fatty acids, glucose and fructose is part of the basic requirements for the provision of energy in the body. High access of saturated longchain fatty acids (LCFA), glucose and fructose can facilitate the development of metabolic diseases, particularly the metabolic syndrome and type-2 diabetes mellitus (T2DM). Research has been done to find substances which decelerate or inhibit intestinal resorption of these specific food components. Promising targets are the inhibition of intestinal long-chain fatty acid (FATP2, FATP4), glucose (SGLT1, GLUT2) and fructose (GLUT2, GLUT5) transporters by plant extracts and by pure substances. The largest part of active components in plant extracts belongs to the group of polyphenols. This review summarizes the knowledge about binding sites of named transporters and lists the plant extracts which were tested in Caco-2 cells regarding uptake inhibition. PMID- 30301207 TI - A Versatile Strategy for the Synthesis of 4,5-Dihydroxy-2,3-Pentanedione (DPD) and Related Compounds as Potential Modulators of Bacterial Quorum Sensing. AB - Resistance to antibiotics is an increasingly serious threat to global public health and its management translates to significant health care costs. The validation of new Gram-negative antibacterial targets as sources for potential new antibiotics remains a challenge for all the scientists working in this field. The interference with bacterial Quorum Sensing (QS) mechanisms represents a potentially interesting approach to control bacterial growth and pursue the next generation of antimicrobials. In this context, our research is focused on the discovery of novel compounds structurally related to (S)-4,5-dihydroxy-2,3 pentanedione, commonly known as (S)-DPD, a small signaling molecule able to modulate bacterial QS in both Gram-negative and Gram-positive bacteria. In this study, a practical and versatile synthesis of racemic DPD is presented. Compared to previously reported syntheses, the proposed strategy is short and robust: it requires only one purification step and avoids the use of expensive or hazardous starting materials as well as the use of specific equipment. It is therefore well suited to the synthesis of derivatives for pharmaceutical research, as demonstrated by four series of novel DPD-related compounds described herein. PMID- 30301208 TI - Isolation of Nb2Se9 Molecular Chain from Bulk One-Dimensional Crystal by Liquid Exfoliation. AB - The optimum solvent for Nb2Se9 dispersion, which is a new type of one dimensional (1D) material, is investigated. Among several solvents (16 solvents in total), strong dispersion was observed in benzyl alcohol, isopropyl alcohol, isobutyl alcohol, and diacetone alcohol, which have medium dielectric constants in the range of 10 to 30 and surface tension in the range of 25 to 35 mJ m-2. 1D Nb2Se9 chains, whose size is less than 10 nm, are well dispersed and it is possible to disperse mono-chains of 1 nm or less in a specific dispersion region. The 1D unit chain with dangling bond free surface and high volume to area ratio is expected to be used in applications that utilize the surface of the material. Such dispersion is an important first step towards various potential applications and is an indispensable scientific goal for the practical applications of Nb2Se9. PMID- 30301209 TI - Exploring the Emerging Evolution Trends of Urban Resilience Research by Scientometric Analysis. AB - : Numerous studies in urban resilience have been published in the past decade. However, only a few publications have tracked the evolution trends of urban resilience research, the findings of which can serve as a useful guide for scholars to foresee worth-effort research areas and make the best use of precious time and resources. In order to fill the research gap, this study performed a scientometric analysis on the evolution trends of urban resilience research using a versatile software package-CiteSpace. The scientomentric analysis focuses on distribution of lead authors and their institutions, high frequency categories and keywords, high influential journals, author contribution, and evolutionary trends based on co-author analysis, co-word analysis, co-citation analysis and cluster analysis of documents. This study discoveries that first, the U.S., England, Australia, Canada, China and Sweden are the countries that make the most significant contributions in the advancement of urban resilience research; second, the existing urban resilience research focuses primarily on environmental studies, geography and planning development; third, hot topics of the urban resilience research keep shifting from 1993 to 2016; fourth, the knowledge body of urban resilience research consists of five clusters: resilience exploratory analysis, disaster resilience, urban resilience, urban resilience practice, and social-ecological systems; last, the emerging trends in urban resilience research include defining urban resilience, adaptation model, case studies, analytical methods and urban social-ecological systems, resulting in cutting-edge research areas in urban resilience. PMID- 30301210 TI - Arginine in the FARM and SARM: A Role in Chain-Length Determination for Arginine in the Aspartate-Rich Motifs of Isoprenyl Diphosphate Synthases from Mycobacterium tuberculosis. AB - Isoprenyl chains are found in many important metabolites. These are derived from precursors of the appropriate length produced by isoprenyl diphosphate synthases (IDSs). The human pathogen Mycobacterium tuberculosis makes various isoprenoids/terpenoids, with important roles in their biosynthesis played by two closely related IDSs, encoded by grcC1 (Rv0562) and grcC2 (Rv0989c), with Rv0989c generating the 10-carbon precursor (E)-geranyl diphosphate (GPP), and Rv0562 the 20-carbon precursor (E,E,E)-geranylgeranyl diphosphate (GGPP). Intriguingly, while Rv0562 contains the prototypical trans-IDS first and second aspartate-rich (DDxxD) motifs (FARM and SARM, respectively), Rv0989c uniquely contains arginine in place of the second Asp in the FARM and first Asp in the SARM. Here site directed mutagenesis of the corresponding residues in both Rv0562 and Rv0989c reveals that these play a role in determination of product chain length. Specifically, substitution of Asp for the Arg in the FARM and SARM of Rv0989c leads to increased production of the longer 15-carbon farnesyl diphosphate (FPP), while substitution of Arg for the corresponding Asp in Rv0562 leads to increased release of shorter products, both FPP and GPP. Accordingly, while the primary role of the FARM and SARM is known to be chelation of the divalent magnesium ion co-factors that assist substrate binding and catalysis, the Arg substitutions found in Rv0989c seem to provide a novel means by which product chain length is moderated, at least in these M. tuberculosis IDSs. PMID- 30301211 TI - Consensus-Based Sequential Estimation of Process Parameters via Industrial Wireless Sensor Networks. AB - Process parameter estimation, to a large extent, determines the industrial production quality. However, limited sensors can be deployed in a traditional wired manner, which results in poor process parameter estimation in hostile environments. Industrial wireless sensor networks (IWSNs) are techniques that enrich sampling points by flexible sensor deployment and then purify the target by collaborative signal denoising. In this paper, the process industry scenario is concerned, where the workpiece is transferred on the belt and the parameter estimate is required before entering into the next process stage. To this end, a consensus-based sequential estimation (CSE) framework is proposed which utilizes the co-design of IWSN and parameter state estimation. First, a group-based network deployment strategy, together with a TDMA (Time division multiple access) based scheduling scheme is provided to track and sample the moving workpiece. Then, by matching to the tailored IWSN, the sequential estimation algorithm, which is based on the consensus-based Kalman estimation, is developed, and the optimal estimator that minimizes the mean-square error (MSE) is derived under the uncertain wireless communications. Finally, a case study on temperature estimation during the hot milling process is provided. The results show that the estimation error can be reduced to less than 3 ? C within a limited time period, although the measurement error can be more than 100 ? C in existing systems with a single-point temperature sensor. PMID- 30301212 TI - Protected Natural Areas: In Sickness and in Health. AB - Numerous studies show the benefits that contact with the natural environment have for human health, but there are few studies on the role of Protected Natural Areas (PNAs), either from the preventive point of view or on their potential benefits, on individuals with health problems. A study was made of the relationship between the visitation of Montseny Natural Park and Biosphere Reserve and health, from the perspective of a population group with different diseases. A total of 250 patients resident in the areas near the park were surveyed, recording their beliefs about the benefits of nature, as well as the reasons for visiting and the activities associated with health that they carried out in the park. The pure air is the most valued benefit (27.2%), particularly for those with allergies. The majority (57%) visit the park for health reasons. High levels (82%) of exercise are recorded, especially by patients with heart diseases (85%), and 65% exercised in the park. More physical activity is mentioned among those that visit the park most often, particularly among those that carried it out for health reasons. Plants were collected for medicinal use by 39.6%. The study confirmed the significant role of the Montseny Natural Park and Biosphere Reserve as a health resource for individuals with diseases that live near it. It also corroborates the beneficial effects that the PNA provide in human health. PMID- 30301215 TI - Elastic Properties of Magnetorheological Elastomers in a Heterogeneous Uniaxial Magnetic Field. AB - Magnetorheological elastomers (MREs) are stimulus-responsive soft materials that consist of polymeric matrices and magnetic particles. In this study, large-strain response of MREs with 5 vol % of carbonyl iron (CI) particles is experimentally characterized for two different conditions: (1) shear deformation in a uniform magnetic field; and (2), compression in a heterogeneous uniaxial magnetic field. For condition (1), dynamic viscoelastic measurements were performed using a rheometer with a rotor disc and an electric magnet that generated a uniform magnetic field on disc-like material samples. For condition (2), on the other hand, three permanent magnets with different surface flux densities were used to generate a heterogeneous uniaxial magnetic field under cylindrical material samples. The experimental results were mathematically modeled, and the relationship between them was investigated. We also used finite-element method (FEM) software to estimate the uniaxial distributions of the magnetic field in the analyzed MREs for condition (2), and developed mathematical models to describe these phenomena. By using these practicable techniques, we established a simple macroscale model of the elastic properties of MREs under simple compression. We estimated the elastic properties of MREs in the small-strain regime (neo-Hookean model) and in the large-strain regime (Mooney-Rivlin model). The small-strain model explains the experimental results for strains under 5%. On the other hand, the large-strain model explains the experimental results for strains above 10%. PMID- 30301214 TI - Pathophysiological Alterations of Redox Signaling and Endocannabinoid System in Granulocytes and Plasma of Psoriatic Patients. AB - Inflammatory granulocytes are characterized by an oxidative burst, which may promote oxidative stress and lipid modification both in affected tissues and on a systemic level. On the other hand, redox signaling involving lipid peroxidation products acting as second messengers of free radicals play important yet not fully understood roles in the pathophysiology of inflammation and various stress associated disorders. Therefore, the aim of this study was to evaluate the onset of oxidative stress and alterations of enzyme-dependent lipid metabolism resulting from redox imbalance in granulocytes and plasma obtained from patients with psoriasis vulgaris or psoriatic arthritis in comparison to the healthy subjects. The results obtained revealed enhanced activity of pro-oxidant enzymes nicotinamide adenine dinucleotide phosphate (NADPH) and xanthine oxidases in granulocytes with a decrease of enzymatic and non-enzymatic antioxidants in the plasma of psoriatic patients. The nuclear factor erythroid 2-related factor 2 (Nrf2) and its regulators were increased in both forms of psoriasis while heme oxygenase 1 levels were increased only in psoriasis vulgaris. The redox imbalance was associated with decreased levels of phospholipids and of free polyunsaturated fatty acids but with enhanced activity of enzymes involved in lipid metabolism (phospholipase A2, acetylhydrolase PAF, cyclooxygenases 1 and 2) and increased lipid peroxidation products 4-hydroxynonenal, isoprostanes, and neuroprostanes. Increased endocannabinoids and G protein-coupled receptor 55 were observed in both forms of the disease while expression of the cannabinoid type 1 receptor (CB1) was increased only in patients with psoriatic arthritis, which is opposite to the cannabinoid type 2 receptor. This receptor was increased only in psoriasis vulgaris. Changes in protein expression promoted the apoptosis of granulocytes by increased caspases mainly in psoriasis vulgaris. This study indicates that inhibition of the Nrf2 pathway in psoriatic arthritis promotes a redox imbalance. In addition, increased expression of CB1 receptors leads to increased oxidative stress, lipid modifications, and inflammation, which, in turn, may promote the progression of psoriasis into the advanced, arthritic form of the disease. PMID- 30301213 TI - Role of Hypoxic Stress in Regulating Tumor Immunogenicity, Resistance and Plasticity. AB - Hypoxia, or gradients of hypoxia, occurs in most growing solid tumors and may result in pleotropic effects contributing significantly to tumor aggressiveness and therapy resistance. Indeed, the generated hypoxic stress has a strong impact on tumor cell biology. For example, it may contribute to increasing tumor heterogeneity, help cells gain new functional properties and/or select certain cell subpopulations, facilitating the emergence of therapeutic resistant cancer clones, including cancer stem cells coincident with tumor relapse and progression. It controls tumor immunogenicity, immune plasticity, and promotes the differentiation and expansion of immune-suppressive stromal cells. In this context, manipulation of the hypoxic microenvironment may be considered for preventing or reverting the malignant transformation. Here, we review the current knowledge on how hypoxic stress in tumor microenvironments impacts on tumor heterogeneity, plasticity and resistance, with a special interest in the impact on immune resistance and tumor immunogenicity. PMID- 30301216 TI - Recent Trends in Potential Therapeutic Applications of the Dietary Flavonoid Didymin. AB - Didymin (isosakuranetin 7-O-rutinoside) is an orally bioactive dietary flavonoid glycoside first found in citrus fruits. Traditionally, this flavonoid has long been used in Asian countries as a dietary antioxidant. Recent studies have provided newer insights into this pleiotropic compound, which could regulate multiple biological activities of many important signaling molecules in health and disease. Emerging data also presented the potential therapeutic application of dietary flavonoid glycoside didymin against cancer, neurological diseases, liver diseases, cardiovascular diseases, and other diseases. In this review, we briefly introduce the source and extraction methods of didymin, and summarize its potential therapeutic application in the treatment of various diseases, with an emphasis on molecular targets and mechanism that contributes to the observed therapeutic effects. The dietary flavonoid didymin can be used to affect health and disease with multiple therapeutic targets, and it is anticipated that this review will stimulate the future development of this potential dietary medicine. PMID- 30301217 TI - Synthesis, Molecular Docking and in Vitro Screening of Some Newly Synthesized Triazolopyridine, Pyridotriazine and Pyridine-Pyrazole Hybrid Derivatives. AB - A series of novel pyridine and fused pyridine derivatives have been prepared starting from 6-(3,4-dimethylphenyl)-2-hydrazinyl-4-(thiophen-2-yl)-pyridine-3 carbonitrile 1 which on treatment with appropriate formic acid, acetic acid/ acetic anhydride, benzoyl chloride and/or carbon disulfide afforded the corresponding triazolopyridine derivatives 2-5. Also, treatment of hydrazide 1 with diethyloxalate, chloroacetyl chloride, chloroacetic acid and/or 1,2 dichloroethane yielded the corresponding pyridotriazine derivatives 7-10. Further transformation of compound 1 with a different active methylene group, namely acetyl acetone, diethylmalonate, ethyl cyanoacetate, ethyl benzoylacetate and/or ethyl acetoacetate, produced the pyridine-pyrazole hybrid derivatives 11-15. These newly synthesized compounds (1-15) were subjected to in silico molecular docking screenings towards GlcN-6-P synthase as the target protein. The results revealed moderate to good binding energies of the ligands on the target protein. All the newly prepared products exhibited antimicrobial and antioxidant activity. PMID- 30301218 TI - FBXL7 Upregulation Predicts a Poor Prognosis and Associates with a Possible Mechanism for Paclitaxel Resistance in Ovarian Cancer. AB - Paclitaxel (PTX) is a common regimen used to treat patients with ovarian cancer. Although approximately 60% of ovarian cancer patients exhibit a pathologic complete response (pCR), approximately 40% of patients appear to be insensitive to PTX adjuvant therapy. Thus, identifying a useful biomarker to predict pCR would be of great help to ovarian cancer patients who decide to receive PTX treatment. We found that FBXL7 was downregulated in OVSAHO (PTX-sensitive) but upregulated in KURAMOCHI (PTX-resistant) cells after PTX treatment at cytotoxic concentrations. Moreover, our data showed that the fold change of FBXL7 expression post-treatment with PTX was causally correlated with the 50% inhibitory concentrations (IC50) of PTX in a panel of ovarian cancer cell lines. In assessments of progression-free survival probability, high levels of FBXL7 transcript strongly predicted a poor prognosis and unfavorable response to PTX based chemotherapy in patients with ovarian cancer. The knockdown of FBXL7 predominantly enhanced the cytotoxic effectiveness of PTX on the PTX-resistant KURAMOCHI cells. FBXL7 may be a useful biomarker for predicting complete pathologic response in ovarian cancer patients who decide to receive post operative PTX therapy. PMID- 30301219 TI - Effects of Different Techniques of Malolactic Fermentation Induction on Diacetyl Metabolism and Biosynthesis of Selected Aromatic Esters in Cool-Climate Grape Wines. AB - The effects of different malolactic bacteria fermentation techniques on the bioconversion of aromatic compounds in cool-climate grape wines were examined. During three wine seasons, red and white grape wines were produced using various malolactic fermentation induction techniques: Coinoculation, sequential inoculation, and spontaneous process. Volatile compounds (diacetyl and the products of its metabolism, and selected ethyl fatty acid esters) were extracted by solid phase microextraction. Compounds were identified with a multidimensional gas chromatograph-GC * GC-ToFMS with ZOEX cryogenic (N2) modulator. Sensory evaluation of the wines was also performed. It was found that the fermentation derived metabolites studied were affected by the malolactic bacteria inoculation regime. Quantitatively, ethyl lactate, diethyl succinate, and ethyl acetate dominated as esters with the largest increase in content. The total concentration of ethyl esters was highest for the coinoculation technique, while the highest concentration of diacetyl was noted for the spontaneous technique. Controlled malolactic fermentation, especially using the coinoculation technique, can be proposed as a safe and efficient enological practice for producing quality cool climate grape wines enriched with fruity, fresh, and floral aromas. PMID- 30301221 TI - Object Detection in Very High-Resolution Aerial Images Using One-Stage Densely Connected Feature Pyramid Network. AB - Object detection in very high-resolution (VHR) aerial images is an essential step for a wide range of applications such as military applications, urban planning, and environmental management. Still, it is a challenging task due to the different scales and appearances of the objects. On the other hand, object detection task in VHR aerial images has improved remarkably in recent years due to the achieved advances in convolution neural networks (CNN). Most of the proposed methods depend on a two-stage approach, namely: a region proposal stage and a classification stage such as Faster R-CNN. Even though two-stage approaches outperform the traditional methods, their optimization is not easy and they are not suitable for real-time applications. In this paper, a uniform one-stage model for object detection in VHR aerial images has been proposed. In order to tackle the challenge of different scales, a densely connected feature pyramid network has been proposed by which high-level multi-scale semantic feature maps with high quality information are prepared for object detection. This work has been evaluated on two publicly available datasets and outperformed the current state of-the-art results on both in terms of mean average precision (mAP) and computation time. PMID- 30301220 TI - Maize WRKY Transcription Factor ZmWRKY106 Confers Drought and Heat Tolerance in Transgenic Plants. AB - WRKY transcription factors constitute one of the largest transcription factor families in plants, and play crucial roles in plant growth and development, defense regulation and stress responses. However, knowledge about this family in maize is limited. In the present study, we identified a drought-induced WRKY gene, ZmWRKY106, based on the maize drought de novo transcriptome sequencing data. ZmWRKY106 was identified as part of the WRKYII group, and a phylogenetic tree analysis showed that ZmWRKY106 was closer to OsWRKY13. The subcellular localization of ZmWRKY106 was only observed in the nucleus. The promoter region of ZmWRKY106 included the C-repeat/dehydration responsive element (DRE), low temperature responsive element (LTR), MBS, and TCA-elements, which possibly participate in drought, cold, and salicylic acid (SA) stress responses. The expression of ZmWRKY106 was induced significantly by drought, high temperature, and exogenous abscisic acid (ABA), but was weakly induced by salt. Overexpression of ZmWRKY106 improved the tolerance to drought and heat in transgenic Arabidopsis by regulating stress-related genes through the ABA-signaling pathway, and the reactive oxygen species (ROS) content in transgenic lines was reduced by enhancing the activities of superoxide dismutase (SOD), peroxide dismutase (POD), and catalase (CAT) under drought stress. This suggested that ZmWRKY106 was involved in multiple abiotic stress response pathways and acted as a positive factor under drought and heat stress. PMID- 30301223 TI - Testing New Concepts for Crop Cultivation in Space: Effects of Rooting Volume and Nitrogen Availability. AB - Long term human missions to the Moon and Mars, rely on life support systems for food production and regeneration of resources. In the EU H2020 TIME SCALE project, an advanced life support system concept was developed to facilitate plant research and technology demonstration under different gravity conditions. Ground experiments assessed irrigation systems and effects of rooting- and nutrient solution volume. The maximal allowed volume for existing International Space Station research facilities (3.4 L) was able to support cultivation of two lettuce heads for at least 24 days. A smaller rooting volume (0.6 L) increased root biomass after 24 days, but induced a 5% reduction in total biomass at day 35. Regulating effects of nitrate supply on plant water fluxes in light and dark were also investigated. At low concentrations of nitrate in the nutrient solution, both transpiration and stomatal conductance increased rapidly with increasing nitrate concentration. During day-time this increase levelled off at high concentrations, while during nigh-time there was a distinct decline at supra optimal concentrations. Plants supplied with nitrate concentrations as low as 1.25 mM did not show visible signs of nutrient stress or growth reduction. These findings hold promise for both reducing the environmental impact of terrestrial horticulture and avoiding nutrient stress in small scale closed cultivation systems for space. PMID- 30301222 TI - MDA-MB-231 Breast Cancer Cells and Their CSC Population Migrate Towards Low Oxygen in a Microfluidic Gradient Device. AB - Most cancer deaths are caused by secondary tumors formed through metastasis, yet due to our limited understanding of this process, prevention remains a major challenge. Recently, cancer stem cells (CSCs) have been proposed as the source of metastases, but only little is known about their migratory behavior. Oxygen gradients in the tumor have been linked to directional migration of breast cancer cells. Here, we present a method to study the effect of oxygen gradients on the migratory behavior of breast CSCs using a microfluidic device. Our chip contains a chamber in which an oxygen gradient can be generated between hypoxic (<1%) and ambient (21%) conditions. We tracked the migration of CSCs obtained from MDA-MB 231 breast cancer cells, and found that their migration patterns do not differ from the average MDA-MB-231 population. Surprisingly, we found that the cells migrate towards low oxygen levels, in contrast with an earlier study. We hypothesize that in our device, migration is exclusively due to the pure oxygen gradient, whereas the effects of oxygen in earlier work were obscured by additional cues from the tumor microenvironment (e.g., nutrients and metabolites). These results open new research directions into the role of oxygen in directing cancer and CSC migration.

AB - Nitroxyl (HNO) plays a critical role in many physiological processes which includes vasorelaxation in heart failure, neuroregulation, and myocardial contractility. Powerful imaging tools are required to obtain information for understanding the mechanisms involved in these in vivo processes. In order to develop a rapid and high sensitive probe for HNO detection in living cells and the zebrafish model organism, 2-((2-(benzothiazole-2yl)benzylidene) amino)benzoic acid (AbTCA) as a ligand, and its corresponding copper(II) complex Cu(II)-AbTCA were synthesized. The reaction results of Cu(II)-AbTCA with Angeli's salt showed that Cu(II)-AbTCA could detect HNO quantitatively in a range of 40-360 uM with a detection limit of 9.05 uM. Furthermore, Cu(II)-AbTCA is more selective towards HNO over other biological species including thiols, reactive nitrogen, and reactive oxygen species. Importantly, Cu(II)-AbTCA was successfully applied to detect HNO in living cells and zebrafish. The collective data reveals that Cu(II) AbTCA could be used as a potential probe for HNO detection in living systems.

AB - A co-based porous metal-organic framework (MOF) of zeolitic imidazolate framework 67 (ZIF-67) and carbon nanofibers (CNFs) was utilized to prepare a ZIF-67/CNFs composite via a one-pot synthesis method. Scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD) were employed to investigate the morphology, structure, and composition of the resulting composite. A novel high-performance non-enzymatic electrochemical sensor was constructed based on the ZIF-67/CNFs composite. The ZIF-67/CNFs based sensor exhibited enhanced electrocatalytic activity towards H2O2 compared to a pure ZIF-67-based sensor, due to the synergistic effects of ZIF-67 and CNFs. Meanwhile, chronoamperometry was utilized to explore the detection performance of the sensor. Results showed the sensor displayed high-efficiency electrocatalysis towards H2O2 with a detection limit of 0.62 MUM (S/N = 3), a sensitivity of 323 uA mM-1 cm-2, a linear range from 0.0025 to 0.19 mM, as well as satisfactory selectivity and long-term stability. Furthermore, the sensor demonstrated its application potential in the detection of H2O2 in food. PMID- 30301226 TI - Composition Analysis by UPLC-PDA-ESI (-)-HRMS and Antioxidant Activity Using Saccharomyces cerevisiae Model of Herbal Teas and Green Teas from Hainan. AB - Different teas from everywhere are very useful and have been extensively studied. We studied the antioxidant activity of herbal teas and green teas from Hainan, Mallotus oblongifolius Muell. Arg. (MO), Ilex kudingcha C.J. Tseng (KD), Camellia sinensis var. assamica (J. W. Mast.) Kitam. Hainan Dayezhong (DY), and Camellia sinensis (L.) O. Ktze. (produced from Hainan Baisha (BS)). The total phenol content and total flavonoid content from water extracts, resin extracts and fractions of herbal teas and green teas were compared. Later, eight fractions of herbal teas and green teas were subjected to UPLC-PDA-ESI-(-)-HRMS. We determined 1-diphenyl -2-picryl-hydrazyl radical and hydroxyl free radical scavenging activity by electron paramagnetic resonance spectroscopy. We subjected Saccharomyces cerevisiae to hydrogen peroxide, stress and evaluated antioxidant activity of herbal teas and green teas in cellulo. The experiment identified more than 14 potential antioxidant compounds from herbal teas and green teas. The herbal teas and green teas had a clearance rate higher than ferulic acid at the same concentrations. MO best reduced intracellular oxidation levels and increased catalase, glutathione reductase activities, glutathione reduced and glutathione oxidized content. KD had the highest cell survival rate and reduced cell lipid peroxidation. DY best improved superoxide dismutase activity and BS was the most active in the halo test. Therefore, we concluded that MO had stronger antioxidant activity than other herbal teas and green teas from Hainan, especially, which reduce S. cerevisiae oxidative stress under H2O2 stress. PMID- 30301228 TI - Green Procurement Relationships Development under Carbon Emissions Regulations: A Bi-Level Programming Approach. AB - A multi-period Stackelberg game is adopted to study a green procurement relationship between manufacturers and suppliers in a supply chain. The manufacturers are considered as leaders, while the suppliers are modelled as followers in this Stackelberg game. Accordingly, a mixed binary linear bi-level programming model is developed to elaborate the game in consideration of carbon tax scheme. The upper level (the leader) aims at selecting a proper number of suitable suppliers to provide heterogeneous raw materials at the lowest operational cost. The objective of the lower level (the follower) is to find optimal purchasing quantities of raw materials. In addition, two lemmas are introduced to transform the mixed linear bi-level programming model into a single level linear programming model. The numerical example illustrates that: (1) the manufacturer prefers to adopt the multiple sourcing strategy due to the flexibility; (2) keeping stable supplies and large order volumes could effectively reduce carbon emissions for the suppliers and make the supply chain greener. PMID- 30301227 TI - Evaluation of Circulating MicroRNA Biomarkers in the Acute Pancreatic Injury Dog Model. AB - This study aimed to evaluate the usefulness of four microRNAs (miRNAs) in an acute pancreatic injury dog model. Acute pancreatitis was induced by infusion of cerulein for 2 h (7.5 MUg/kg/h). The levels of well-known miRNAs, microRNA-216a (miR-216a) and microRNA-375 (miR-375), and new candidates microRNA-551b (miR 551b), and microRNA-7 (miR-7), were measured at 0, 0.5, 1, 2, 6, 12, and 24 h with serum amylase and lipase, and histopathological examination was performed. Among the four miRNAs, miR-216a and miR-375, and serum enzymes were significantly increased by cerulein treatment. The expression levels of miRNAs and serum enzymes peaked at 2-6 h with a similar pattern; however, the overall increases in miR-216a and miR-375 levels were much higher than those of the serum enzyme biomarkers. Increased levels of miR-216a and miR-375 were most highly correlated to the degree of individual histopathological injuries of the pancreas, and showed much greater dynamic response than serum enzyme biomarkers. Twenty-four hour time-course analysis in this study revealed time-dependent changes of miRNA expression levels, from initial increase to decrease by predose level in acute pancreatitis. Our findings demonstrate that, in dogs, miR-216a and miR-375 have the potential to sensitively detect pancreatitis and reflect well the degree of pancreatic injury, whereas miR-551b and miR-7 do not. PMID- 30301230 TI - Microdialysis-Assessed Adipose Tissue Metabolism, Circulating Cytokines and Outcome in Critical Illness. AB - Microdialysis (MD) can provide continuous information about tissue composition. To assess in critically ill patients adipose tissue metabolic patterns, the relationships between metabolic patterns and blood cytokine concentration associations of adipose tissue energy metabolism and clinical outcome we studied 203 mechanically ventilated general intensive care unit (ICU) patients. Upon ICU admission an MD catheter was inserted into the subcutaneous adipose tissue of the upper thigh to measure lactate (L), glucose, pyruvate (P), and glycerol. Serum concentrations of IL-10, IL-6, IL-8, and TNF-alpha were determined within 48 h from ICU admission. Mitochondrial dysfunction was defined as L/P ratio >30 and pyruvate >=70 MUmol/L, ischemia as L/P ratio >30 and pyruvate <70 MUmol/L and no ischemia/no mitochondrial dysfunction (i.e. aerobic metabolism) was as L/P ratio <=30. Metabolism was aerobic in 74% of patients. In 13% of patients there was biochemical evidence of ischemia and in 13% of patients of mitochondrial dysfunction. Mitochondrial dysfunction was associated with poor outcome. In conclusion, MD showed that about two thirds of critically ill patients have normal aerobic adipose tissue metabolism. Mitochondrial dysfunction was not common but was associated with poor outcome. Identifying subgroups of critically ill patients is crucial as different treatment strategies may improve survival. PMID- 30301229 TI - Whole Genome Characterization of Orthopoxvirus (OPV) Abatino, a Zoonotic Virus Representing a Putative Novel Clade of Old World Orthopoxviruses. AB - Orthopoxviruses (OPVs) are diffused over the complete Eurasian continent, but previously described strains are mostly from northern Europe, and few infections have been reported from Italy. Here we present the extended genomic characterization of OPV Abatino, a novel OPV isolated in Italy from an infected Tonkean macaque, with zoonotic potential. Phylogenetic analysis based on 102 conserved OPV genes (core gene set) showed that OPV Abatino is most closely related to the Ectromelia virus species (ECTV), although placed on a separate branch of the phylogenetic tree, bringing substantial support to the hypothesis that this strain may be part of a novel OPV clade. Extending the analysis to the entire set of genes (coding sequences, CDS) further substantiated this hypothesis. In fact the genome of OPV Abatino included more CDS than ECTV; most of the extra genes (mainly located in the terminal genome regions), showed the highest similarity with cowpox virus (CPXV); however vaccinia virus (VACV) and monkeypox virus (MPXV) were the closest OPV for certain CDS. These findings suggest that OPV Abatino could be the result of complex evolutionary events, diverging from any other previously described OPV, and may indicate that previously reported cases in Italy could represent the tip of the iceberg yet to be explored. PMID- 30301231 TI - TRP Channels as Drug Targets to Relieve Itch. AB - Although acute itch has a protective role by removing irritants to avoid further damage, chronic itch is debilitating, significantly impacting quality of life. Over the past two decades, a considerable amount of stimulating research has been carried out to delineate mechanisms of itch at the molecular, cellular, and circuit levels. There is growing evidence that transient receptor potential (TRP) channels play important roles in itch signaling. The purpose of this review is to summarize our current knowledge about the role of TRP channels in the generation of itch under both physiological and pathological conditions, thereby identifying them as potential drug targets for effective anti-itch therapies. PMID- 30301232 TI - Effect of Straw Checkerboards on Wind Proofing, Sand Fixation, and Ecological Restoration in Shifting Sandy Land. AB - Due to their simple layout and adaptability to various environments, straw checkerboards are widely used to control windblown sand in China. To fully understand the wind proofing and sand-fixing benefits of different board specifications, and to determine the restorative effects of straw checkerboard, we tested different sizes of checkerboard, determined their performance as a windbreak and in trapping shifting sand, and constructed models based on wind tunnel tests, enabling the wind speed flow field to be analysed. We also sampled the soil in areas where straw checkerboards had been established for several years and analysed the trends in soil physical and chemical properties over time. We found that all sizes of straw checkerboard effectively reduced the wind speed near the surface and formed a protected area, with the best protective effect achieved for a one-meter board. All sizes of straw checkerboard effectively intercepted windblown sand to form surface accumulation, with the one-meter board again showing the best performance. The use of a straw checkerboard also effectively improved the physical and chemical properties of soil and promoted ecological restoration. These results indicate that straw checkerboards are a low cost engineering measure that could play an important role in desertification control and the ecological restoration of sandy land ecosystems. PMID- 30301233 TI - Mitigated Impact of Provision of Local Foods Combined with Nutrition Education and Counseling on Young Child Nutritional Status in Cambodia. AB - BACKGROUND: In Cambodia, stunting and wasting affect, respectively, 32% and 10% of children 0-59 months while 55% are anemic. Our research aims to assess the efficiency of two local foods combined with nutritional education and counseling (CEN) activities as compared to CEN alone on improving child nutritional status and dietary intake. METHODS: A cluster-randomized controlled trial was conducted in Soth Nikum area over a six-month period among children 6-23 months (n = 360) assigned to receive either moringa +CEN, cricket +CEN or CEN alone. Anthropometric measurements were performed and hemoglobin and ferritin levels assessed. RESULTS: Overall, no significant increase in the mean length/height-for age z-score was observed, although a small increase of the weight-for length/height was noted in intervention groups. Hemoglobin and ferritin mean values increased in all groups. The degree of satisfaction of energy, proteins, iron, and zinc requirements improved in all groups, but to a greater extent in the intervention groups and more children were healthy. CONCLUSION: Our research shows no significant impact of the provision of two local foods combined with CEN on the improvement of child nutritional status as compared to CEN alone. However, children consuming them better fulfilled their energy, iron, and zinc requirements and were healthier. PMID- 30301234 TI - Design of Antibacterial Agents: Alkyl Dihydroxybenzoates against Xanthomonas citri subsp. citri. AB - Xanthomonas citri subsp. citri (Xcc) causes citrus canker, affecting sweet orange producing areas around the world. The current chemical treatment available for this disease is based on cupric compounds. For this reason, the objective of this study was to design antibacterial agents. In order to do this, we analyzed the anti-Xcc activity of 36 alkyl dihydroxybenzoates and we found 14 active compounds. Among them, three esters with the lowest minimum inhibitory concentration values were selected; compounds 4 (52 MUM), 16 (80 MUM) and 28 (88 MUM). Our study demonstrated that alkyl dihydroxybenzoates cause a delay in the exponential phase. The permeability capacity of alkyl dihydroxybenzoates in a quarter of MIC was compared to nisin (positive control). Compound 28 was the most effective (93.8), compared to compound 16 (41.3) and compound 4 (13.9) by percentage values. Finally, all three compounds showed inhibition of FtsZ GTPase activity, and promoted changes in protofilaments, leading to depolymerization, which prevents bacterial cell division. In conclusion, heptyl dihydroxybenzoates (compounds 4, 16 and 28) are promising anti-Xcc agents which may serve as an alternative for the control of citrus canker. PMID- 30301236 TI - Determinants of Breeding Farmers' Safe Use of Veterinary Drugs: A Theoretical and Empirical Analysis. AB - As food safety has attracted the widespread attention of society, the quality safety of agricultural products has become an important part of food safety and also confronts multiple challenges. In fact, the safe use of veterinary drugs in the production process has become one of important guarantees for the quality safety of agricultural products. It's of great significance to regulate the breeding farmers' safe use of veterinary drugs and to create a safe and healthy production environment for agricultural products. A field survey of individual and large-scale swine breeding farmers in four typical provinces including Henan, Shandong, Jiangxi and Guizhou generated 397 questionnaires. This field survey conducted the internal and external classification of breeding farmers' safe use of veterinary drugs and defined the breeding farmers' safe use of veterinary drugs in the light of dosage, type and standardized operation of veterinary drugs. Based on Lewin's behavior theory, the survey used the structural equation modeling method to systematically examine the generation path of breeding farmers' safe use of veterinary drugs. The comprehensive analysis reveals that breeding farmers' knowledge about veterinary drugs, the attitudes toward the government supervision and the market environment of breeding activities all exert some effects on breeding farmers' use of veterinary drugs. Some suggestions and countermeasures for breeding farmers' safe use of veterinary drugs are provided as follows: First, more efforts should be pumped into publicity and instruction so that breeding farmers can have a better understanding of veterinary drugs. Second, preferential policies should be formulated to encourage the breeding farmers' participation in the industrial organizations of swine breeding farmers, and advocate the industrial organizations' active provision of different technical trainings. Third, the communication and cooperation platform should be created among breeding farmers, slaughter and processing plants and supermarkets, the poultry insurance market should be regulated, and the insurance purchase process should be improved. Fourth, when more subsidies for harm-free and environment-friendly veterinary drugs are provided, more serious punishments should be imposed on the unsafe use of veterinary drugs to offer policy support for the breeding farmers' standardized use of veterinary drugs. PMID- 30301235 TI - Movement of the RecG Motor Domain upon DNA Binding Is Required for Efficient Fork Reversal. AB - RecG catalyzes reversal of stalled replication forks in response to replication stress in bacteria. The protein contains a fork recognition ("wedge") domain that binds branched DNA and a superfamily II (SF2) ATPase motor that drives translocation on double-stranded (ds)DNA. The mechanism by which the wedge and motor domains collaborate to catalyze fork reversal in RecG and analogous eukaryotic fork remodelers is unknown. Here, we used electron paramagnetic resonance (EPR) spectroscopy to probe conformational changes between the wedge and ATPase domains in response to fork DNA binding by Thermotoga maritima RecG. Upon binding DNA, the ATPase-C lobe moves away from both the wedge and ATPase-N domains. This conformational change is consistent with a model of RecG fully engaged with a DNA fork substrate constructed from a crystal structure of RecG bound to a DNA junction together with recent cryo-electron microscopy (EM) structures of chromatin remodelers in complex with dsDNA. We show by mutational analysis that a conserved loop within the translocation in RecG (TRG) motif that was unstructured in the RecG crystal structure is essential for fork reversal and DNA-dependent conformational changes. Together, this work helps provide a more coherent model of fork binding and remodeling by RecG and related eukaryotic enzymes. PMID- 30301237 TI - Associations between Body Mass Index and Urban "Green" Streetscape in Cleveland, Ohio, USA. AB - Public health researchers are increasingly interested in assessing the impact of neighborhood environment on physical activities and chronic health issues among humans. Walkable streets and proximity to green space have long been believed to promote active lifestyles in cities, which contribute to positive health outcomes among residents. Traditionally, urban environmental metrics were calculated at the area level to describe the physical environment of neighborhoods. However, considering the fact that streets are the basic unit for human activities in cities, it is important to understand how the streetscape environment can influence human health conditions. In this study, we investigated the influence of street greenery and walkability on body mass index in Cleveland, Ohio, USA. Different from the area level and overhead view greenery metrics, we used the green view index calculated from the Google Street View to represent the amount of street greenery. The Walk Score was used to indicate the walkability of neighborhoods also at the street level. Statistical analysis results show that the Walk Score has a more significant association with decreased BMI for males than females and the street greenery has a more significant association with decreased BMI for females than males in Cleveland, Ohio. The results of this study would provide a reference for designing gender-specific healthy cities. PMID- 30301239 TI - BATS: Adaptive Ultra Low Power Sensor Network for Animal Tracking. AB - In this paper, the BATS project is presented, which aims to track the behavior of bats via an ultra-low power wireless sensor network. An overview about the whole project and its parts like sensor node design, tracking grid and software infrastructure is given and the evaluation of the project is shown. The BATS project includes a lightweight sensor node that is attached to bats and combines multiple features. Communication among sensor nodes allows tracking of bat encounters. Flight trajectories of individual tagged bats can be recorded at high spatial and temporal resolution by a ground node grid. To increase the communication range, the BATS project implemented a long-range telemetry system to still receive sensor data outside the standard ground node network. The whole system is designed with the common goal of ultra-low energy consumption while still maintaining optimal measurement results. To this end, the system is designed in a flexible way and is able to adapt its functionality according to the current situation. In this way, it uses the energy available on the sensor node as efficient as possible. PMID- 30301240 TI - Should I Eat or Should I Go? Acridid Grasshoppers and Their Novel Host Plants: Potential for Biotic Resistance. AB - Novel, non-coevolved associations between introduced plants and native insect herbivores may lead to changes in trophic interactions in native communities, as well as to substantial economic problems. Although some studies in invasion ecology demonstrated that native herbivores can preferentially feed on introduced plants and therefore contribute to the biotic resistance of native communities to plant invasions, the role of acridid grasshoppers as native generalist insect herbivores is largely overlooked. This systematic review aimed to identify patterns of grasshopper feeding preferences for native versus introduced plants and, consequently, a potential of grasshoppers to provide biotic resistance of native communities. The analysis of 63 records of feeding preference trials for 28 North-American grasshopper species (retrieved from 2146 studies published during 1967-2017) has demonstrated a preference of grasshoppers for introduced host plants, and identified 12 preferred introduced plants with high or middle invasive ranks. A significant effect of the life stage (p < 0.001), but not the experimental environment, plant material, and measurements, on grasshopper preferences for introduced plants was also detected. Overall, results suggest a potential of acridid grasshoppers to contribute to the biotic resistance of native communities. The review also provides methodological recommendations for future experimental studies on grasshopper-host plant interactions. PMID- 30301238 TI - EEG-Based Control for Upper and Lower Limb Exoskeletons and Prostheses: A Systematic Review. AB - Electroencephalography (EEG) signals have great impact on the development of assistive rehabilitation devices. These signals are used as a popular tool to investigate the functions and the behavior of the human motion in recent research. The study of EEG-based control of assistive devices is still in early stages. Although the EEG-based control of assistive devices has attracted a considerable level of attention over the last few years, few studies have been carried out to systematically review these studies, as a means of offering researchers and experts a comprehensive summary of the present, state-of-the-art EEG-based control techniques used for assistive technology. Therefore, this research has three main goals. The first aim is to systematically gather, summarize, evaluate and synthesize information regarding the accuracy and the value of previous research published in the literature between 2011 and 2018. The second goal is to extensively report on the holistic, experimental outcomes of this domain in relation to current research. It is systematically performed to provide a wealthy image and grounded evidence of the current state of research covering EEG-based control for assistive rehabilitation devices to all the experts and scientists. The third goal is to recognize the gap of knowledge that demands further investigation and to recommend directions for future research in this area. PMID- 30301241 TI - Acute Effects of Substitution, and Addition, of Carbohydrates and Fat to Protein on Gastric Emptying, Blood Glucose, Gut Hormones, Appetite, and Energy Intake. AB - Whey protein, when ingested on its own, load-dependently slows gastric emptying and stimulates gut hormone concentrations in healthy young men. The aim of this study was to determine the effects of substitution, and addition, of carbohydrate (dextrose) and fat (olive oil) to whey protein. In randomized, double-blind order, 13 healthy young men (age: 23 +/- 1 years, body mass index: 24 +/- 1 kg/m2) ingested a control drink (450 mL; ~2 kcal/'control') or iso-volumetric drinks containing protein/carbohydrate/fat: (i) 14 g/28 g/12.4 g (280 kcal/'M280'), (ii) 70 g/28 g/12.4 g (504kcal/'M504'), and (iii) 70 g/0 g/0 g (280 kcal/'P280'), on 4 separate study days. Gastric emptying (n = 11, 3D ultrasonography), blood glucose, plasma insulin, ghrelin, cholecystokinin (CCK) and glucagon-like peptide-1 (GLP-1) concentrations (0-180 min), appetite (visual analogue scales), and ad-libitum buffet-meal energy intake (180-210 min) were determined. Substitution of protein with carbohydrate and fat was associated with faster gastric emptying (lower 50% emptying time (T50)), reduced suppression of ghrelin, and stimulation of GLP-1 (all P < 0.001); while the addition of carbohydrate and fat to protein did not affect gastric emptying or gut hormone responses significantly. Total energy intake (i.e., drink plus meal) was greater after all caloric drinks than control (P < 0.001). In conclusion, substitution of whey protein with dextrose and olive oil accelerated gastric emptying. Higher protein content of a mixed macronutrient drink increased gut hormone and insulin responses. PMID- 30301242 TI - Lung Diseases: Chronic Respiratory Infections. PMID- 30301243 TI - Decision-Tree Based Meta-Strategy Improved Accuracy of Disorder Prediction and Identified Novel Disordered Residues Inside Binding Motifs. AB - Using computational techniques to identify intrinsically disordered residues is practical and effective in biological studies. Therefore, designing novel high accuracy strategies is always preferable when existing strategies have a lot of room for improvement. Among many possibilities, a meta-strategy that integrates the results of multiple individual predictors has been broadly used to improve the overall performance of predictors. Nonetheless, a simple and direct integration of individual predictors may not effectively improve the performance. In this project, dual-threshold two-step significance voting and neural networks were used to integrate the predictive results of four individual predictors, including: DisEMBL, IUPred, VSL2, and ESpritz. The new meta-strategy has improved the prediction performance of intrinsically disordered residues significantly, compared to all four individual predictors and another four recently-designed predictors. The improvement was validated using five-fold cross-validation and in independent test datasets. PMID- 30301244 TI - An Alanine-to-Valine Substitution in the Residue 175 of Zika Virus NS2A Protein Affects Viral RNA Synthesis and Attenuates the Virus In Vivo. AB - The recent outbreaks of Zika virus (ZIKV), its association with Guillain-Barre syndrome and fetal abnormalities, and the lack of approved vaccines and antivirals, highlight the importance of developing countermeasures to combat ZIKV disease. In this respect, infectious clones constitute excellent tools to accomplish these goals. However, flavivirus infectious clones are often difficult to work with due to the toxicity of some flavivirus sequences in bacteria. To bypass this problem, several alternative approaches have been applied for the generation of ZIKV clones including, among others, in vitro ligation, insertions of introns and using infectious subgenomic amplicons. Here, we report a simple and novel DNA-launched approach based on the use of a bacterial artificial chromosome (BAC) to generate a cDNA clone of Rio Grande do Norte Natal ZIKV strain. The sequence was identified from the brain tissue of an aborted fetus with microcephaly. The BAC clone was fully stable in bacteria and the infectious virus was efficiently recovered in Vero cells through direct delivery of the cDNA clone. The rescued virus yielded high titers in Vero cells and was pathogenic in a validated mouse model (A129 mice) of ZIKV infection. Furthermore, using this infectious clone we have generated a mutant ZIKV containing a single amino acid substitution (A175V) in the NS2A protein that presented reduced viral RNA synthesis in cell cultures, was highly attenuated in vivo and induced fully protection against a lethal challenge with ZIKV wild-type. This BAC approach provides a stable and reliable reverse genetic system for ZIKV that will help to identify viral determinants of virulence and facilitate the development of vaccine and therapeutic strategies. PMID- 30301245 TI - AWRK6, a Novel GLP-1 Receptor Agonist, Attenuates Diabetes by Stimulating Insulin Secretion. AB - Diabetes is a metabolic disorder leading to many complications. The treatment of diabetes mainly depends on hypoglycemic drugs, often with side effects, which drive us to develop novel agents. AWRK6 was a peptide developed from the antimicrobial peptide Dybowskin-2CDYa in our previous study, and the availability of AWRK6 on diabetes intervention was unknown. Here, in vivo and in vitro experiments were carried out to investigate the effects of AWRK6 against diabetes. In diabetic mice, induced by high-fat diet followed by streptozocin (STZ) administration, the daily administration of AWRK6 presented acute and sustained hypoglycemic effects. The plasma insulin was significantly elevated by AWRK6 during an oral glucose tolerance test (OGTT). The relative beta cell mass in diabetic mice was increased by AWRK6 treatment. The body weight and food intake were remarkably reduced by AWRK6 administration. In the mouse pancreatic beta cell line Min6 cells, the intracellular calcium concentration was found to be enhanced under the treatment with AWRK6, and protein kinase A (PKA) inhibitor H-89 and Epac2 inhibitor HJC0350 represented inhibitory effects of the insulinotropic function of AWRK6. By FITC-AWRK6 incubation and GLP-1 receptor (GLP-1R) knockdown, AWRK6 proved to be a novel GLP-1R agonist. In addition, AWRK6 showed no toxicity in cell viability and membrane integrity in Min6 cells, and no hypoglycemia risk and no lethal toxicity in mice. In summary, AWRK6 was found as a novel agonist of GLP-1R, which could stimulate insulin secretion to regulate blood glucose and energy metabolism, via cAMP-calcium signaling pathway, without significant toxicity. The peptide AWRK6 might become a novel candidate for diabetes treatment. PMID- 30301246 TI - Cycle Stability and Hydration Behavior of Magnesium Oxide and Its Dependence on the Precursor-Related Particle Morphology. AB - Thermochemical energy storage is considered as an auspicious method for the recycling of medium-temperature waste heat. The reaction couple Mg(OH)2-MgO is intensely investigated for this purpose, suffering so far from limited cycle stability. To overcome this issue, Mg(OH)2, MgCO3, and MgC2O4.2H2O were compared as precursor materials for MgO production. Depending on the precursor, the particle morphology of the resulting MgO changes, resulting in different hydration behavior and cycle stability. Agglomeration of the material during cyclization was identified as main reason for the decreased reactivity. Immersion of the spent material in liquid H2O decomposes the agglomerates restoring the initial reactivity of the material, thus serving as a regeneration step. PMID- 30301247 TI - Dietary Intake of Vitamin D in the Czech Population: A Comparison with Dietary Reference Values, Main Food Sources Identified by a Total Diet Study. AB - The usual dietary intake of vitamin D was studied in 10 subgroups of the Czech population. Food consumption data was collected using repeated 24 h recall in a national cross-sectional survey (the Study of Individual Food Consumption, SISP04), and the vitamin D content in marketed foods was quantified within the national Total Diet Study (2014-2015). The Monte Carlo Risk Assessment computational model (version MCRA 8.2) was used to assess usual intake. The median vitamin D intakes for the Czech population (aged 4-90 years, both genders) were within a range of 2.5-5.1 MUg/day. The highest median intake, excluding dietary supplements, was observed in men aged 18-64, and the lowest was observed in children aged 4-6 and girls aged 11-17. The main sources in the diet were hen eggs (21-28% of usual dietary intake), fine bakery wares (11-19%), cow's milk and dairy products (7-23%), meat and meat products (4-12%), fish (6-20%), and margarines (7-18%). The dietary intake of vitamin D for more than 95% of the Czech population was below the recommended Dietary Reference Values (DRVs). These findings should encourage public health authorities to support interventions and education and implement new regulatory measures for improving intake. PMID- 30301248 TI - Electrochemical Measurements of Multiwalled Carbon Nanotubes under Different Plasma Treatments. AB - In the present work, we described the post-treatment effects of applying different plasma atmosphere conditions on the electrochemical performances of the multiwalled carbon nanotubes (MWCNTs). For the study, a composite of MWCNTs/Co/Ti was successfully grown on the silicon substrate and then pre-treated with ammonia, oxygen and hydrogen plasma. The composite was characterized by making use of field emission scanning electron microscopy (FESEM) for the surface morphology and Raman spectroscopy for the functionalization. Further, the electrochemical measurements were performed with the use of the cyclic voltammetry (CV) applied in the 0.01 M potassium ferricyanide in 0.1 M KCl solution. On testing, the results indicated that the NH3-treated MWCNTs have the highest efficiency as compared to the other pretreatments and control. This increased performance of NH3 treated sample can be linked to the enhanced surface area of the composite, thereby improved adsorption and associated interaction with that of the analyte molecules at the electrodes. Further comparison of the electrode with that of commercial Dropsens electrodes provided the confirmation for the efficiency of the NH3/MWCNTs, thereby suggesting for the potentiality of applying the NH3 modified electrode towards electrochemical applications.

However, cost effective and compact devices measuring road profiles are not available for production vehicles. This paper presents a longitudinal road profile estimation method as a virtual sensor for vehicle localization without using bulky and expensive sensor systems. An inertial measurement unit installed in the vehicle provides filtered signals of the vehicle's responses to the longitudinal road profile. A disturbance observer was designed to extract the characteristic features of the road profile from the signals measured by the inertial measurement unit. Design synthesis based on a Kalman filter was used for the observer design. A nonlinear damper is explicitly considered to improve the estimation accuracy. Virtual measurement signals are introduced for observability. The suggested methodology estimates the road profile that is sufficiently accurate for localization. Based on the estimated longitudinal road profile, we generated spectrogram plots as the features for localization. The localization is realized by matching the spectrogram plot with pre-indexed plots. The localization using the estimated road profile shows a few meters accuracy, suggesting a possible road profile estimation method as an alternative sensor for vehicle localization.

AB - Background: Poor oral hygiene is associated with metabolic syndrome, systemic diseases, mortality and many chronic diseases. Misperception means a wrong or incorrect understanding or interpretation. Few studies have examined the subjective perception and objective condition of oral health among community adults in rural areas. Methods: This was a cross-sectional, community-based study. Participants were recruited via convenience samples from December 2015 to July 2016. One thousand six (1006) community residents participated in the project, of which 973 fulfilled the inclusion criteria. The average age was 42.8 (SD = 12.3) years, range 20-64, selected from a collaboration local hospital. Results: Most of the participants reported brushing their teeth every day, however, 72% reported seldom brushing their teeth after meals, 54% seldom used dental floss, 64% seldom received dental scaling, 29.5% had experienced a toothache within 6 months, and 30.5% demonstrated significant tooth loss. However, most of them perceived their oral health as good. Misperception of oral health was common, 21.5% among whose number of remaining teeth <25 under-assess their actual oral health. The more number of remaining teeth (p < 0.001) and regular dental check-up (p < 0.01) were positively associated with feeling good about their oral health. After adjusting for potential confounders, clinically significant findings indicated that number of remaining teeth (OR = 3.03, p < 0.001), age (OR = 0.99, p < 0.001), regular dental check-ups/scaling (OR = 1.85, p < 0.001), education (OR = 1.45, p < 0.05), and water consumption (OR = 1.38, p < 0.05) were independently associated with good perceived oral health. Conclusions: The findings showed that subjective self-perception of oral health was not matched with their objective oral condition. Excluding the unmodifiable factors, the clinical implications indicated that oral health promotion programs, particularly for adopting regular dental check-up, healthy diet and oral hygiene habits are urgent in rural areas. PMID- 30301251 TI - Development and Validation of a New Tool to Assess Burden of Dietary Sodium Restriction in Patients with Chronic Heart Failure: The BIRD Questionnaire. AB - (1) Background: Burden scales are useful in estimating the impact of interventions from patients' perspectives. This is overlooked in sodium diet/heart failure (HF). The aim of this study is to develop and validate a specific tool to assess the burden associated with low-sodium diets in HF: the Burden scale In Restricted Diets (BIRD). (2) Methods: Based on the literature and reports from patients, 14 candidate items were identified for the following dietary-related domains: organization, pleasure, leisure, social life, vitality, and self-rated health. The validation study was conducted prospectively. The questionnaire was refined via item reduction according to inter-item correlations and exploratory factor analysis. Internal consistency was determined using Cronbach's alpha (Calpha) and convergent validity by assessing correlations between BIRD and the health-related quality of life (HRQoL) Minnesota Living with HF questionnaire (MLHF). (3) Results: Of the 152 invited patients, 96 (63%) returned the questionnaire. The median score was 6.5 (IQR 2.0-14.0). The results showed good acceptability (non-response rates/item from 2.0% to 12.1%), an excellent internal consistency (Calpha = 0.903) and a good convergent validity (rhos = 0.37 (physical), 0.4 (mental), and 0.45 (global); all p < 0.05). (4) Conclusions: BIRD demonstrates good psychometric properties and is useful to quantify the burden associated with sodium restriction. It may help optimize dietary interventions and improve the overall management of patients with HF.

AB - A new form-stable composite phase change material (PEG/ASB) composed of almond shell biochar (ASB) and polyethylene glycol (PEG) was produced via a simple and easy vacuum impregnation method. The supporting material ASB, which was cost effective, environmentally friendly, renewable and rich in appropriate pore structures, was produced from agricultural residues of almond shells by a simple pyrolysis method, and it was firstly used as the matrix of PEG. Different analysis techniques were applied to investigate the characteristics of PEG/ASB, including structural and thermal properties, and the interaction mechanism between ASB and PEG was studied. The thermogravimetric analysis (TGA) and thermal cycle tests demonstrated that PEG/ASB possessed favorable thermal stability. The differential scanning calorimetry (DSC) curves demonstrated that the capacities for latent heat storage of PEG/ASB were enhanced with increasing PEG weight percentage. Additionally, PEG/ASB had an excellent thermal conductivity of 0.402 W/mK, which was approximately 1.6 times higher than that of the pure PEG due to the addition of ASB. All the study results indicated that PEG/ASB had favorable phase change properties, which could be used for thermal energy storage. PMID- 30301252 TI - Stereotactic Radiosurgery and Immune Checkpoint Inhibitors in the Management of Brain Metastases. AB - Brain metastases traditionally carried a poor prognosis with an overall survival of weeks to months in the absence of treatment. Radiation therapy modalities include whole brain radiation therapy (WBRT) and stereotactic radiosurgery (SRS). WBRT delivers a relatively low dose of radiation, has neurocognitive sequelae, and has not been investigated for its immunostimulatory effects. Furthermore, WBRT exposes the entire intracranial tumor immune microenvironment to radiation. SRS delivers a high dose of conformal radiation with image guidance to minimize dose to surrounding normal brain tissue, and appears to promote anti-tumor immunity. In parallel with many of these discoveries, immune checkpoint inhibitors (ICIs) have demonstrated a survival advantage in multiple malignancies commonly associated with brain metastases (e.g., melanoma). Combination SRS and ICI are theorized to be synergistic in anti-tumor immunity directed to brain metastases. The purpose of this review is to explore the synergy of SRS and ICIs, including pre-clinical data, existing clinical data, and ongoing prospective trials. PMID- 30301255 TI - Grain Refinement by Second Phase Particles under Applied Stress in ZK60 Mg Alloy with Y through Phase Field Simulation. AB - Based on the principle of grain refinement caused by the second-phase particles, a phase field model was built to describe the recrystallization process in the ZK60 alloy system with Y added under applied stress between temperatures 573 and 673 K for 140 min duration. The simulation of grain growth with second phase particles and applied stress during annealing process on industrial scale on the condition of real time-space was achieved. Quantitative analysis was carried out and some useful laws were revealed in ZK60 alloy system. The second phase particles had a promoting effect on the grain refinement, however the effect weakened significantly when the content exceeded 1.5%. Our simulation results reveal the existence of a critical range of second phase particle size of 0.3-0.4 MUm, within which a microstructure of fine grains can be obtained. Applied stress increased the grain coarsening rate significantly when the stress was more than 135 MPa. The critical size of the second phase particles was 0.4-0.75 MUm when the applied stress was 135 MPa. Finally, a microstructure with a grain size of 11.8-13.8 MUm on average could be obtained when the second phase particles had a content of 1.5% and a size of 0.4-0.75 MUm with an applied stress less than 135 Mpa after 30 min annealing at 573 K. PMID- 30301254 TI - The Inhibitory Effect of Flavonoid Aglycones on the Metabolic Activity of CYP3A4 Enzyme. AB - Flavonoids are natural compounds that have been extensively studied due to their positive effects on human health. There are over 4000 flavonoids found in higher plants and their beneficial effects have been shown in vitro as well as in vivo. However, data on their pharmacokinetics and influence on metabolic enzymes is scarce. The aim of this study was to focus on possible interactions between the 30 most commonly encountered flavonoid aglycones on the metabolic activity of CYP3A4 enzyme. 6beta-hydroxylation of testosterone was used as marker reaction of CYP3A4 activity. Generated product was determined by HPLC coupled with diode array detector. Metabolism and time dependence, as well as direct inhibition, were tested to determine if inhibition was reversible and/or irreversible. Out of the 30 flavonoids tested, 7 significantly inhibited CYP3A4, most prominent being acacetin that inhibited 95% of enzyme activity at 1 uM concentration. Apigenin showed reversible inhibition, acacetin, and chrysin showed combined irreversible and reversible inhibition while chrysin dimethylether, isorhamnetin, pinocembrin, and tangeretin showed pure irreversible inhibition. These results alert on possible flavonoid-drug interactions on the level of CYP3A4. PMID- 30301256 TI - Restoring Large Defect of Posterior Tooth by Indirect Composite Technique: A Case Report. AB - Advances in adhesive dentistry have led to increased use of indirect restorations. In some situations, indirect composite techniques are more advantageous than direct composite filling techniques, such as establishing proper occlusal and interproximal anatomy, reducing polymerization shrinkage stress, and promoting the degree of conversion. This article presents a case about restoring the lower right first molar with extensive loss of tooth structure by the composite onlay to achieve a proper anatomic form and rehabilitate chewing function. This one-year clinical case encourages clinicians to manage large decay of posterior tooth conservatively. The given functional and esthetic outcomes demonstrate the promising applicability of the indirect composite technique. PMID- 30301257 TI - Poisson's Ratio of Closed-Cell Aluminium Foams. AB - A nondestructive impulse excitation technique was used to investigate Poisson's ratio of powder metallurgical pure closed-cell aluminium foams according to ASTM E 1876 within the foam density range of 0.430-1.390 g.cm-3. Instead of a constant value of 0.34, as according to Gibson and Ashby's assumption for the Poisson's ratio of metallic foams, the decrease of the Poisson's ratio with decreasing foam density was observed. Observed Poisson's ratio data were in the range of 0.21 0.34. To check the validity of the results, the Young's modulus was calculated using Poisson's ratio and its dependence on relative density was successfully modelled using the usual power law function with characteristic exponent of 1.72 +/- 0.1. This confirms that the obtained experimental results for Poisson's ratio are valid. Finally, rule of mixture and percolation theory were used to model the observed decrease of Poisson's ratio with increasing porosity. PMID- 30301258 TI - LTCC Packaged Ring Oscillator Based Sensor for Evaluation of Cell Proliferation. AB - A complementary metal-oxide-semiconductor (CMOS) chip biosensor was developed for cell viability monitoring based on an array of capacitance sensors utilizing a ring oscillator. The chip was packaged in a low temperature co-fired ceramic (LTCC) module with a flip chip bonding technique. A microcontroller operates the chip, while the whole measurement system was controlled by PC. The developed biosensor was applied for measurement of the proliferation stage of adherent cells where the sensor response depends on the ratio between healthy, viable and multiplying cells, which adhere onto the chip surface, and necrotic or apoptotic cells, which detach from the chip surface. This change in cellular adhesion caused a change in the effective permittivity in the vicinity of the sensor element, which was sensed as a change in oscillation frequency of the ring oscillator. The sensor was tested with human lung epithelial cells (BEAS-2B) during cell addition, proliferation and migration, and finally detachment induced by trypsin protease treatment. The difference in sensor response with and without cells was measured as a frequency shift in the scale of 1.1 MHz from the base frequency of 57.2 MHz. Moreover, the number of cells in the sensor vicinity was directly proportional to the frequency shift. PMID- 30301259 TI - A Novel Tb@Sr-MOF as Self-Calibrating Luminescent Sensor for Nutritional Antioxidant. AB - Sesamol, is well-known antioxidant and can reduce the rate of oxidation and prolong expiration date. It is also potentially antimutagenic and antihepatotoxic, the detection of sesamol is important and remains a huge challenge. Herein, a new 3D alkaline earth Sr metal organic framework [Sr(BDC)DMACH2O]n (BDC = benzene-1,4-dicarboxylate; DMAC = N,N-dimethylacetamide) is synthesized and a probe based on Tb3+ functionalized Sr-MOF. The Tb(3+)@Sr-MOF showed good luminescence and thermal property. Due to the energy competition between sesamol and ligand, the luminescence intensity of sesamol increases meantime luminescence intensity of Tb3+ decreases, the ratio of the emission intensities (I344/I545) linearly increases with sesamol in concentrations ranging from 1 * 10-7 to 8 * 10-4 M. Furthermore, the fluorescence-detected circular test shows that the composite Tb(3+)@Sr-MOF can serve as ratiometric sensor for sensing of sesamol. This is the first example for self-calibrated detecting sesamol based on metal-organic framework (MOF). PMID- 30301261 TI - Operation Mechanism of a MoS2/BP Heterojunction FET. AB - The electrical characteristics and operation mechanism of a molybdenum disulfide/black phosphorus (MoS2/BP) heterojunction device are investigated herein. Even though this device showed a high on-off ratio of over 1 * 107, with a lower subthreshold swing of ~54 mV/dec and a 1fA level off current, its operating mechanism is closer to a junction field-effect transistor (FET) than a tunneling FET. The off-current of this device is governed by the depletion region in the BP layer, and the band-to-band tunneling current does not contribute to the rapid turn-on and extremely low off-current. PMID- 30301260 TI - Uremia Impacts VE-Cadherin and ZO-1 Expression in Human Endothelial Cell-to-Cell Junctions. AB - Endothelial dysfunction in uremia can result in cell-to-cell junction loss and increased permeability, contributing to cardiovascular diseases (CVD) development. This study evaluated the impact of the uremic milieu on endothelial morphology and cell junction's proteins. We evaluated (i) serum levels of inflammatory biomarkers in a cohort of chronic kidney disease (CKD) patients and the expression of VE-cadherin and Zonula Occludens-1 (ZO-1) junction proteins on endothelial cells (ECs) of arteries removed from CKD patients during renal transplant; (ii) ECs morphology in vitro under different uremic conditions, and (iii) the impact of uremic toxins p-cresyl sulfate (PCS), indoxyl sulfate (IS), and inorganic phosphate (Pi) as well as of total uremic serum on VE-cadherin and ZO-1 gene and protein expression in cultured ECs. We found that the uremic arteries had lost their intact and continuous endothelial morphology, with a reduction in VE-cadherin and ZO-1 expression. In cultured ECs, both VE-cadherin and ZO-1 protein expression decreased, mainly after exposure to Pi and uremic serum groups. VE-cadherin mRNA expression was reduced while ZO-1 was increased after exposure to PCS, IS, Pi, and uremic serum. Our findings show that uremia alters cell-to-cell junctions leading to an increased endothelial damage. This gives a new perspective regarding the pathophysiological role of uremia in intercellular junctions and opens new avenues to improve cardiovascular outcomes in CKD patients. PMID- 30301262 TI - Genomic Deletion of BAP1 and CDKN2A Are Useful Markers for Quality Control of Malignant Pleural Mesothelioma (MPM) Primary Cultures. AB - Malignant pleural mesothelioma (MPM) is a deadly cancer that is caused by asbestos exposure and that has limited treatment options. The current standard of MPM diagnosis requires the testing of multiple immunohistochemical (IHC) markers on formalin-fixed paraffin-embedded tissue to differentiate MPM from other lung malignancies. To date, no single biomarker exists for definitive diagnosis of MPM due to the lack of specificity and sensitivity; therefore, there is ongoing research and development in order to identify alternative biomarkers for this purpose. In this study, we utilized primary MPM cell lines and tested the expression of clinically used biomarker panels, including CK8/18, Calretinin, CK 5/6, CD141, HBME-1, WT-1, D2-40, EMA, CEA, TAG72, BG8, CD15, TTF-1, BAP1, and Ber Ep4. The genomic alteration of CDNK2A and BAP1 is common in MPM and has potential diagnostic value. Changes in CDKN2A and BAP1 genomic expression were confirmed in MPM samples in the current study using Fluorescence In situ Hybridization (FISH) analysis or copy number variation (CNV) analysis with digital droplet PCR (ddPCR). To determine whether MPM tissue and cell lines were comparable in terms of molecular alterations, IHC marker expression was analyzed in both sample types. The percentage of MPM biomarker levels showed variation between original tissue and matched cells established in culture. Genomic deletions of BAP1 and CDKN2A, however, showed consistent levels between the two. The data from this study suggest that genomic deletion analysis may provide more accurate biomarker options for MPM diagnosis. PMID- 30301263 TI - Segmentation and Multi-Scale Convolutional Neural Network-Based Classification of Airborne Laser Scanner Data. AB - The classification of point clouds is a basic task in airborne laser scanning (ALS) point cloud processing. It is quite a challenge when facing complex observed scenes and irregular point distributions. In order to reduce the computational burden of the point-based classification method and improve the classification accuracy, we present a segmentation and multi-scale convolutional neural network-based classification method. Firstly, a three-step region-growing segmentation method was proposed to reduce both under-segmentation and over segmentation. Then, a feature image generation method was used to transform the 3D neighborhood features of a point into a 2D image. Finally, feature images were treated as the input of a multi-scale convolutional neural network for training and testing tasks. In order to obtain performance comparisons with existing approaches, we evaluated our framework using the International Society for Photogrammetry and Remote Sensing Working Groups II/4 (ISPRS WG II/4) 3D labeling benchmark tests. The experiment result, which achieved 84.9% overall accuracy and 69.2% of average F1 scores, has a satisfactory performance over all participating approaches analyzed. PMID- 30301265 TI - Precision Motion Control of a Linear Permanent Magnet Synchronous Machine Based on Linear Optical-Ruler Sensor and Hall Sensor. AB - The linear optical-ruler sensor with 1um precision mounted in the linear permanent magnet synchronous machine (LPMSM) is used for measuring the mover position of LPMSM in order to enhance the precision of a measured mover position. Due to nonlinear friction and uncertainty effects, linear controllers are very hard to achieve good mover positioning of LPMSM. The proposed adaptive amended Elman neural network backstepping (AAENNB) control system is adopted for controlling the LPMSM drive system to bring about the mover positioning precision of LPMSM. Firstly, a backstepping scheme is posed for controlling the tracing motion of the LPMSM drive system. The proposed backstepping control system, which is applied in the mover position of the LPMSM drive system, possesses better dynamic control performance and robustness to uncertainties for the tracing trajectories. Because of the LPMSM with nonlinear and time-varying dynamic characteristics, an adaptive amended Elman neural network uncertainty observer (AAENNUO) is posed to estimate the required lumped uncertainty. According to the Lyapunov stability theorem, on-line parameter training methodology of the amended Elman neural network (AENN) can be derived by use of adaptive law. The error estimated law is proposed to compensate for the observed error induced by the AENN with adaptive law. Furthermore, to help improve convergence and to obtain better learning performance, the mended particle swarm optimization (PSO) algorithm is utilized for adjusting the varied learning rate of the weights in the AENN. At last, these experimental results, which show better performance, are verified by the proposed control system. PMID- 30301264 TI - Synthesis and Biological Evaluation of Novel Indole-Derived Thioureas. AB - A series of 2-(1H-indol-3-yl)ethylthiourea derivatives were prepared by condensation of 2-(1H-indol-3-yl)ethanamine with appropriate aryl/alkylisothiocyanates in anhydrous media. The structures of the newly synthesized compounds were confirmed by spectroscopic analysis and the molecular structures of 8 and 28 were confirmed by X-ray crystallography. All obtained compounds were tested for antimicrobial activity against Gram-positive cocci, Gram-negative rods and for antifungal activity. Microbiological evaluation was carried out over 20 standard strains and 30 hospital strains. Compound 6 showed significant inhibition against Gram-positive cocci and had inhibitory effect on the S. aureus topoisomerase IV decatenation activity and S. aureus DNA gyrase supercoiling activity. Compounds were tested for cytotoxicity and antiviral activity against a large panel of DNA and RNA viruses, including HIV-1 and other several important human pathogens. Interestingly, derivative 8 showed potent activity against HIV-1 wild type and variants bearing clinically relevant mutations. Newly synthesized tryptamine derivatives showed also a wide spectrum activity, proving to be active against positive- and negative-sense RNA viruses. PMID- 30301266 TI - Widely Linear Adaptive Instantaneous Frequency Estimation in Vector Hydrophones. AB - To solve the problem that the time-frequency resolution of Short-Time Fourier Transform (STFT) is constrained by the window length and the moving step of the short time window, and to utilize the merits of a widely linear method, a novel instantaneous frequency estimation method in vector hydrophone was proposed. In this paper, a complex variable was constructed. It is composed of sound pressure and particle velocity as its real part and imaginary part, respectively. The constructed variable was approved to be second order noncircular (improper). For the modelling of noncircular signals, the standard linear estimation is not adequate and the pseudo-covariance matrix should also be taken into consideration. As a result, a widely linear adaptive instantaneous frequency estimation algorithm and its three solutions based on the augmented complex least mean square (ACLMS) method are presented to estimate the instantaneous frequency in vector hydrophones. The results of simulations and laboratory experiments prove that this approach based on a widely linear model performs better compared to STFT and strict linear filter methods. PMID- 30301267 TI - Citrus aurantium L. and Its Flavonoids Regulate TNBS-Induced Inflammatory Bowel Disease through Anti-Inflammation and Suppressing Isolated Jejunum Contraction. AB - Inflammatory bowel disease (IBD) is a serious digestive system disease, for which the clinical therapeutic choices remain limited. Dried fruits of Citrus aurantium L. (CAL) are a traditional medicine used for regulation of the digestive system. The aim of this study was to identify the regulatory effects of CAL on IBD and to clarify the mechanism of the active compounds. In trinitrobenzene sulfonic acid induced IBD rats, 125 to 500 mg/kg of oral CAL significantly alleviated weight loss and diarrhea, decreased colitis inflammatory cell infiltration, and inhibited pro-inflammatory cytokine production. The mechanisms of characteristic flavonoids in CAL were evaluated involving inflammation and intestine contraction aspects. Naringenin, nobiletin, and hesperetin showed anti-inflammatory effects on lipopolysaccharide-induced RAW cells. The mechanism may be related to the inhibition of the tumor necrosis factor-alpha (TNF-alpha)-induced nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappaB) pathway to suppress cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) expressions. Naringenin and nobiletin showed inhibitory effects on isolated jejunum contraction. The mechanism of naringenin is partly related to COX, NOS, inositol triphosphate (IP3), and finally, to decreased jejunum motility. This study demonstrated that CAL, and its flavonoids' regulatory effects on IBD through anti inflammation and inhibition of intestine muscle contraction, can provide basic information on developing new drugs or supplements against IBD based on CAL. PMID- 30301268 TI - Job Satisfaction and Perceived Health in Spanish Construction Workers during the Economic Crisis. AB - The attitude towards work, either satisfaction or dissatisfaction, could influence the way in which workers perceive their health status. To check this hypothesis, this study analyses job satisfaction and its relationship with occupational health perception of Spanish construction workers. A descriptive, cross-sectional, observational study was carried out through a socio-demographic data questionnaire, the General Scale of Job Satisfaction and the SF-36 Health Survey. The study was conducted from January 2014 to June 2015, on a sample of 302 individuals belonging to Andalusian companies using the stratified random method to access companies from different provinces and sizes. The findings indicate that work experience in the sector increases general satisfaction: workers above 55 years of age are more satisfied with their work than those between 36 and 45. Likewise, workers with an experience of 2-5 years show higher levels of overall satisfaction, in opposition to workers with 6 months and 2 years of experience. On the other hand, workers without a contract and interns are the most dissatisfied in job terms. Also, there is a positive correlation between job satisfaction and the positive dimensions of health perception (physical functioning and physical and social role functioning), as well as a negative correlation between job satisfaction and bodily pain and general health perceived. PMID- 30301269 TI - Resveratrol Attenuates Staphylococcus Aureus-Induced Monocyte Adhesion through Downregulating PDGFR/AP-1 Activation in Human Lung Epithelial Cells. AB - Staphylococcus aureus (S. aureus) is a very common Gram-positive bacterium. It is widely distributed in air, soil, and water. S. aureus often causes septicemia and pneumonia in patients. In addition, it is considered to play a key role in mediating cell adhesion molecules upregulation. Resveratrol is a natural antioxidant with diverse biological effects, including the modulation of immune function, anti-inflammation, and cancer chemoprevention. In this study, we proved that S. aureus-upregulated vascular cell adhesion molecule-1 (VCAM-1) expression in human lung epithelial cells (HPAEpiCs) was inhibited by resveratrol. We also observed that resveratrol downregulated S. aureus-enhanced leukocyte count in bronchoalveolar lavage (BAL) fluid in mice. In HPAEpiCs, S. aureus stimulated c Src, PDGFR, p38 MAPK, or JNK1/2 phosphorylation, which was inhibited by resveratrol. S. aureus induced the adhesion of THP-1 cells (a human monocytic cell line) to HPAEpiCs, which was also reduced by resveratrol. Finally, we found that S. aureus induced c-Src/PDGFR/p38 MAPK and JNK1/2-dependent c-Jun and ATF2 activation and in vivo binding of c-Jun and ATF2 to the VCAM-1 promoter, which were inhibited by resveratrol. Thus, resveratrol functions as a suppressor of S. aureus-induced inflammatory signaling, not only by inhibiting VCAM-1 expression but also by diminishing c-Src, PDGFR, JNK1/2, p38 MAPK, and AP-1 activation in HPAEpiCs. PMID- 30301270 TI - In Vivo Evaluation of Antirrhinum majus' Wound-Healing Activity. AB - Mediterranean-native perennial plant Antirrhinum majus was scrutinized in this study for its antioxidant activity and its total phenolic content in order to test for the plant's wound-healing capability. The traditional uses of this plant to treat gum scurvy, various tumors, ulcers, and hemorrhoids were the main idea behind this study. Leaves and flowers of the A. majus were extracted by maceration. Pilot qualitative phytochemical tests were made to check the presence of various secondary metabolites. Quantitatively, the flowers' macerate indicated superlative results regarding antioxidant activity and total phenolic content. However, the in vivo wound-healing capability study was made using 30 Wistar strain albino rats. This innovative part of the study revealed that the healing power of the flowers' extract ointment (5% w/w) was superior compared to the leaves' extract (5% w/w) and the positive-control ointments (MEBO) (1.5% w/w) (p <= 0.001). This activity was assessed by visual examination, wound-length measurement, and estimation of hydroxyproline content. Antirrhinum majus is a promising plant to be considered for wound healing. However, further testing (including histological examination and high-performance liquid chromatography (HPLC) analysis) is necessary to understand more about its mechanisms of action. PMID- 30301272 TI - Comparison of Perceived and Observed Hand Hygiene Compliance in Healthcare Workers in MERS-CoV Endemic Regions. AB - This study investigated healthcare workers' perceptions of hand hygiene practices by comparing personal reports, as assessed by questionnaires, to direct observations of the workers' hand hygiene practices. The study employed a cross sectional research design. Observations were made using a 16-item checklist, based on three sources: Centers for Disease Control and Prevention (CDC), World Health Organization (WHO), and Boyce and Pittet's guidelines of hand hygiene. The checklist was used for both direct-observation and self-reported data collection purposes. Pearson correlation and Multivariate Analysis of Covariance (MANCOVA) were utilized to statistically determine the relationship between healthcare workers' reports of hand hygiene practices and observed hand hygiene behaviors. The study was conducted in the outpatient examination rooms and emergency departments of three types of hospitals in the Eastern region of Saudi Arabia where Middle East respiratory syndrome coronavirus (MERS-CoV) is endemic and is observed in routine cases and outbreaks. The total sample size included 87 physicians and nurses recruited while on duty during the scheduled observation periods, with each healthcare worker being observed during individual medical examinations with at least three patients. No statistically significant correlations between the healthcare workers' perceptions of hand hygiene practices and healthcare workers' actual behaviors were evident. Based on the self-report questionnaires, significant differences were found between physicians' and nurses' hand hygiene practices reports. Healthcare workers clearly understand the importance of careful hand hygiene practices, but based on researchers' observations, the medical personnel failed to properly implement protocol-driven hand hygiene applications. However, the significant differences between physicians' and nurses' self-reports suggest further inquiry is needed to fully explore these discrepancies. PMID- 30301271 TI - Enhancing Skin Health: By Oral Administration of Natural Compounds and Minerals with Implications to the Dermal Microbiome. AB - The history of cosmetics goes back to early Egyptian times for hygiene and health benefits while the history of topical applications that provide a medicinal treatment to combat dermal aging is relatively new. For example, the term cosmeceutical was first coined by Albert Kligman in 1984 to describe topical products that afford both cosmetic and therapeutic benefits. However, beauty comes from the inside. Therefore, for some time scientists have considered how nutrition reflects healthy skin and the aging process. The more recent link between nutrition and skin aging began in earnest around the year 2000 with the demonstrated increase in peer-reviewed scientific journal reports on this topic that included biochemical and molecular mechanisms of action. Thus, the application of: (a) topical administration from outside into the skin and (b) inside by oral consumption of nutritionals to the outer skin layers is now common place and many journal reports exhibit significant improvement for both on a variety of dermal parameters. Therefore, this review covers, where applicable, the history, chemical structure, and sources such as biological and biomedical properties in the skin along with animal and clinical data on the oral applications of: (a) collagen, (b) ceramide, (c) beta-carotene, (d) astaxanthin, (e) coenzyme Q10, (f) colostrum, (g) zinc, and (h) selenium in their mode of action or function in improving dermal health by various quantified endpoints. Lastly, the importance of the human skin microbiome is briefly discussed in reference to the genomics, measurement, and factors influencing its expression and how it may alter the immune system, various dermal disorders, and potentially be involved in chemoprevention. PMID- 30301274 TI - Granulin A Synergizes with Cisplatin to Inhibit the Growth of Human Hepatocellular Carcinoma. AB - Cisplatin is one of the most potent chemotherapy drugs widely used for cancer treatment. However, due to resistance and toxicity, the application of cisplatin for the treatment of hepatocellular carcinoma (HCC) is limited. Our previous study has shown that granulin A (GRN A), an anticancer peptide, is able to interact with enolase1 (ENO1) and inhibit the growth of HCC in vitro. In the present study, we studied the synergistic effect of the combination of cisplatin and GRN A for the inhibitory effect on HCC. An 3-(4,5-dimethylthiazol-2-yl)-5-(3 carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay and Chou Talalay approaches revealed that the combination of GRN A and cisplatin displayed potent synergistic effect. The colony formation and cell viability of HCC cells were inhibited significantly in cells treated with the combination of cisplatin and GRN A, compared with cells treated with cisplatin or GRN A alone. Overexpression of ENO1 diminished the synergistic effect of GRN A and cisplatin in HCC cells. The combination of the two drugs exhibited a more obvious inhibitory effect on cancer cell apoptosis, as analyzed by the cytometry flow, mitochondrial membrane potential (MMP) and western blot analysis. An in vivo study confirmed that the combined use of the two drugs displayed more potent antitumor activity compared to mice treated with cisplatin and GRN A alone; the inhibitory rate of tumor growth was 65.46% and 68.94%, respectively, in mice treated with GRN A and cisplatin. However, the inhibitory rate increased to 86.63% in mice treated with the combination of the two drugs. This study provides evidence that the combination of GRN A and cisplatin is able to sensitize the liver cancer to cisplatin, and that targeting ENO1 is a promising approach for enhancing the antitumor activity of cisplatin.

AB - Carbohydrate analyses are often challenging due to the structural complexity of these molecules, as well as the lack of suitable analytical tools for distinguishing the vast number of possible isomers. The coupled technique, ion mobility-mass spectrometry (IM-MS), has been in use for two decades for the analysis of complex biomolecules, and in recent years it has emerged as a powerful technique for the analysis of carbohydrates. For carbohydrates, most studies have focused on the separation and characterization of isomers in biological samples. IM-MS is capable of separating isomeric ions by drift time, and further characterizing them by mass analysis. Applications of IM-MS in carbohydrate analysis are extremely useful and important for understanding many biological mechanisms and for the determination of disease states, although efforts are still needed for higher sensitivity and resolution. PMID- 30301273 TI - Zinc Finger Readers of Methylated DNA. AB - DNA methylation is a prevalent epigenetic modification involved in regulating a number of essential cellular processes, including genomic accessibility and transcriptional outcomes. As such, aberrant alterations in global DNA methylation patterns have been associated with a growing number of disease conditions. Nevertheless, the full mechanisms by which DNA methylation information is interpreted and translated into genomic responses is not yet fully understood. Methyl-CpG binding proteins (MBPs) function as important mediators of this essential process by selectively reading DNA methylation signals and translating this information into down-stream cellular outcomes. The Cys2His2 zinc finger scaffold is one of the most abundant DNA binding motifs found within human transcription factors, yet only a few zinc finger containing proteins capable of conferring selectivity for mCpG over CpG sites have been characterized. This review summarizes our current structural understanding for the mechanisms by which the zinc finger MBPs evaluated to date read this essential epigenetic mark. Further, some of the biological implications for mCpG readout elicited by this family of MBPs are discussed. PMID- 30301276 TI - Impact of Blood or Erythrocyte Membrane Fatty Acids for Disease Risk Prediction: Focusing on Cardiovascular Disease and Chronic Kidney Disease. AB - Fatty acids (FAs) are essential nutrients and main constituents of cell membranes that are involved in the signaling pathway and associated with health conditions. We investigated if blood or erythrocyte membrane FAs can predict the risk of cardiovascular disease (CVD), chronic kidney disease (CKD), and related complications. Omega-3 (n-3) FAs are important predictors for metabolic syndrome, diabetes, CVD, and CKD risks, and the n-3 index is also a good biomarker for sudden cardiac death in coronary artery disease. Linoleic acid, which is one of the major n-6 FAs reflecting recent dietary FA intake, may predict CVD risk and mortality in the general population and patients with CKD. Monounsaturated FAs (MUFAs) are also related to diabetes or diabetic nephropathy. Oleic acid, a major MUFA, is an emerging marker that is related to acute coronary syndrome, low glomerular filtration rate, and vascular calcification in patients with CKD, and can be modified by n-3 FA supplementation. Saturated FAs, trans-FAs, and FA desaturation/elongation are associated with CVD risk; however, few studies have been conducted on patients with CKD. In summary, blood or erythrocyte membrane FA measurements are important for CVD and CKD risk prediction and management. Further studies are needed to elucidate the FAs for their risk predictions. PMID- 30301279 TI - Examining the Effect of Radiant Exposure on Commercial Photopolimerizable Dental Resin Composites. AB - The objective of this study was to evaluate the effect of radiant exposure on the chemical and physical properties of four commercial dental resin composites. The four dental resin composites used were Kalore, Admira, Tetric N-Ceram Bulk Fill, and Filtek Z350 XT. The composites were subjected to three curing protocols: 1000 mW/cm2 for 5 s, 1000 mW/cm2 for 10 s, and 400 mW/cm2 for 25 s. The flexural strength, elastic modulus, water sorption, water solubility, degree of conversion, and polymerization shrinkage were evaluated. The results were analyzed by means of ANOVA and Tukey tests. For Admira and Kalore, significant differences between light exposure protocols were observed for the elastic modulus (p < 0.001), which was higher when a higher amount of radiant exposure was used. For Filtek Z350, differences were only observed for the degree of conversion (p < 0.001), and a higher amount of radiant exposure allowed us to obtain higher values. The Tetric N-Ceram Bulk Fill analysis showed significant differences for the elastic modulus and water sorption (p < 0.001), and specimens that had been subject to a radiant exposure of 10 J/cm2 showed a higher elastic modulus. In most cases, the physical and mechanical properties analyzed were not affected by different radiant exposure values. Other resin-based composite (RBC) characteristics seem to have a greater influence on material properties. PMID- 30301277 TI - Synthesis and Biological Evaluation of Thalidomide Derivatives as Potential Anti Psoriasis Agents. AB - Several thalidomide derivatives were synthesized and evaluated for their anti inflammatory activity. Introduction of the benzyl group to the parent thalidomide is unfavorable in which 2-(1-benzyl-2,6-dioxopiperidin-3-yl)isoindoline-1,3-dione (4a) was inactivated. However, the inhibitory activities on TNF-alpha and IL-6 expression in HaCaT cells were improved by the substitution of a chloro- or methoxy- group at the phenyl position of 4a. The IL-6 inhibitory activity decreased in an order of 5c (69.44%) > 4c (48.73%) > 6c (3.19%) indicating the 3 substituted derivative is more active than the 4-substituted counterpart, which in turn is more active than the 2-substituted counterpart. Among them, 2-[1-(3 chlorobenzyl)-2,6-dioxopiperidin-3-yl]isoindoline-1,3-dione (5c) was found to inhibit TNF-alpha and IL-6 expression in HaCaT cells with a higher potency than thalidomide and no significant cell cytotoxicity was detected at 10 MUM. In psoriasis, Compound 5c reduced IL-6, IL-8, IL-1beta and IL-24 in imiquimod stimulated models. Our results indicated that compound 5c is a potential lead of novel anti-psoriasis agents. Structural optimization of compound 5c and its in vivo assay are ongoing. PMID- 30301278 TI - Passive Sampling of Gaseous Elemental Mercury Based on a Composite TiO2NP/AuNP Layer. AB - Passive sampling systems (PASs) are a low cost strategy to quantify Hg levels in air over both different environmental locations and time periods of few hours to weeks/months. For this reason, novel nanostructured materials have been designed and developed. They consist of an adsorbent layer made of titania nanoparticles (TiO2NPs, <=25 nm diameter) finely decorated with gold nanoparticles. The TiO2NPs functionalization occurred for the photocatalytic properties of titania-anatase when UV-irradiated in an aqueous solution containing HAuCl4. The resulting nanostructured suspension was deposited by drop-casting on a thin quartz slices, dried and then incorporated into a common axial sampler to be investigated as a potential PAS device. The morphological characteristics of the sample were studied by High-Resolution Transmission Electron Microscopy, Atomic Force Microscopy, and Optical Microscopy. UV-Vis spectra showed a blue shift of the membrane when exposed to Hg0 vapors. The adsorbed mercury was thermally desorbed for a few minutes, and then quantified by a mercury vapor analyzer. Such a sampling system reported an efficiency of adsorption that was equal to ~95%. Temperature and relative humidity only mildly affected the membrane performances. These structures seem to be promising candidates for mercury samplers, due to both the strong affinity of gold with Hg, and the wide adsorbing surface. PMID- 30301281 TI - Smartphone Heading Correction Based on Gravity Assisted and Middle Time Simulated Zero Velocity Update Method. AB - Electronic appliances and ferromagnetic materials can be easily found in any building in urban environment. A steady magnetic environment and a pure value of geomagnetic field for calculating the heading of the smartphone in case of pedestrian walking indoors is hard to obtain. Therefore, an independent inertial heading correction algorithm without involving magnetic field but only making full use of the embedded Micro-Electro-Mechanical System (MEMS) Inertial measurement unit (IMU) device in the smartphone is presented in this paper. Aiming at the strict navigation requirements of pedestrian smartphone positioning, the algorithm focused in this paper consists of Gravity Assisted (GA) and Middle Time Simulated-Zero Velocity Update (MTS-ZUPT) methods. With the help of GA method, the different using-mode of the smartphone can be judged based on the data from the gravity sensor of smartphone. Since there is no zero velocity status for handheld smartphone, the MTS-ZUPT algorithm is proposed based on the idea of Zero Velocity Update (ZUPT) algorithm. A Kalman Filtering algorithm is used to restrain the heading divergence at the middle moment of two steps. The walking experimental results indicate that the MTS-ZUPT algorithm can effectively restrain the heading error diffusion without the assistance of geomagnetic heading. When the MTS-ZUPT method was integrated with GA method, the smartphone navigation system can autonomously judge the using-mode and compensate the heading errors. The pedestrian positioning accuracy is significantly improved and the walking error is only 1.4% to 2.0% of the walking distance in using-mode experiments of the smartphone. PMID- 30301280 TI - Synthesis of New Triarylpyrazole Derivatives Possessing Terminal Sulfonamide Moiety and Their Inhibitory Effects on PGE2 and Nitric Oxide Productions in Lipopolysaccharide-Induced RAW 264.7 Macrophages. AB - This article describes the design, synthesis, and in vitro anti-inflammatory screening of new triarylpyrazole derivatives. A total of 34 new compounds were synthesized containing a terminal arylsulfonamide moiety and a different linker between the sulfonamide and pyridine ring at position 4 of the pyrazole ring. All the target compounds were tested for both cytotoxicity and nitric oxide (NO) production inhibition in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. Compounds 1b, 1d, 1g, 2a, and 2c showed the highest NO inhibition percentages and the lowest cytotoxic effect. The most potent derivatives were tested for their ability to inhibit prostaglandin E2 (PGE2) in LPS-induced RAW 264.7 macrophages. The IC50 for nitric oxide inhibition, PGE2 inhibition, and cell viability were determined. In addition, 1b, 1d, 1g, 2a, and 2c were tested for their inhibitory effect on LPS-induced inducible nitric oxide synthase (iNOS) and Cyclooxygenase 2 (COX-2) protein expression as well as iNOS enzymatic activity.

AB - The modified midventral scales on Percina males probably function to induce tactile stimulation of the female during spawning. The midbelly row of modified scales presumably evolved as a result of increased selective advantage of larger and more strongly toothed scales on the midventer; primitive and intermediate conditions in the evolution of the modified scales as well as a distinctly modified row are extant, The morphology of the scales varies seasonally and ontogenetically. The scales are permanent rather than deciduous as described in the literature interspecific variation of the modified scales is pronounced intersubgenerically. less so intrasubgenerically. PMID- 30301282 TI - Compatibility of a Silicone Impression/Adhesive System to FDM-Printed Tray Materials-A Laboratory Peel-off Study. AB - Computer-aided design (CAD) and additive manufacturing (AM) have shown promise in facilitating the fabrication of custom trays. Due to the clinical requirements, custom tray materials should achieve good bonding to the impression/adhesive systems. This study evaluated the retention of three fused deposition modeling (FDM) custom tray materials to a silicone impression/adhesive system before and after gritblasting (GB) by peel-off test. CAD-designed experimental test blocks were printed by FDM using acrylonitrile butadiene styrene (ABS), polyethylene terephthalate glycol copolyester (PETG), and high impact polystyrene (HIPS), and the reference test blocks were made of a conventional light-curing resin (n = 11). Before and after GB, the surface topography of all tray materials was analysed, and the maximum strength of the test block peeled off from a silicone impression/adhesive system was measured. After GB, the arithmetic mean height (Sa) and the valley fluid retention index (Svi) of the four material groups declined (p < 0.05). The peel-off strength of each of the four material groups significantly decreased by GB (p < 0.05), but no statistical difference could be found among them before or after GB. In all peel-off tests, adhesive failure occurred at the adhesive-impression material interface. The results indicated ABS, HIPS, and PETG could provide sufficient adhesion to the adhesive as the conventional light-curing resin, and GB could reduce the roughness generated by FDM and weaken the bonding between the adhesive and the silicone impression. PMID- 30301284 TI - The structure of the ovarian ball and oogenesis in Moniliformis dubius (Acanthocephala). AB - Seven to nine days after infection of the definitive host (rat) by cystacanths, the genital primordium of the female acanthocephalan is transformed from a fragmented mass of cells into discrete ovarian balls. This is accomplished by envelopment of free germinal cells by somatic tissue which originates from the ligament sac primordium. Germinal cell nuclei then undergo repeated mitoses until about 21 days of development, with concurrent formation of oogonial syncytia which occupy the interior of the ovarian balls. Oocytes, derived from these oogonia, move to the periphery of the germinal syncytia for differentiation, growth, fertilization, shell formation, and release from the ovarian ball. After oogonial proliferation ceases, continued growth of the ovarian ball apparently results from increase in size of already present cells. Free-floating mature ovarian balls are found in the dorsal ligament sac; each consists of germ cells in various developmental stages, enveloped and pervaded by a multinucleate matrix syncytium of somatic origin, which functions as a follicle. Spermatozoa pass through the matrix cell for the internal fertilization of mature oocytes. Myelinated structures of an undetermined nature were found to correspond to previously reported polar bodies. After 100 days post-infection, the somatic matrix syncytium begins to manifest the degenerative effects of aging. The germinal tissue exhibits no subcellular signs of senescence by 154 days, but decreases in amount in older worms. PMID- 30301285 TI - The characterization of granular amoebocytes and their possible roles in the asexual reproduction of the polystyelid ascidian, Polyzoa vesiculiphora. AB - The blood cells in the bud and the zooid of the polystyelid ascidian, Polyzoa vesiculiphora, were examined by means of light and electron microscopy to identify the cells that have been named trophocytes. The large blood cells were abundant in the mesenchymal space of the bud, but not in that of the functional zooid. They contained glycogen particles, lipid droplets, large protein granules and autophagosomes in their cytoplasm and were identified as granular amoebocytes. The majority of these cells were specifically phagocytized by phagocytes during bud development and disappeared. These results indicate that the granular amoebocytes virtually represent trophocytes in Polyzoa and may participate in bud development via nutrient supply to the developing tissues. PMID- 30301286 TI - The cytology of the testaceous rhizopod Lesquereusia spiralis (Ehrenberg) Penard. I. Ultrastructure and shell formation. AB - Ultrastructure and shell formation in the testaceous ameba, Lesquereusia spiralis, were investigated with both scanning and transmission electron microscopy and X-ray microanalysis. The nucleus, surrounded by a fibrous lamina, contains multiple nucleoli. The cytoplasm, containing a well developed granular endoplasmic reticulum, also contains remnants of starch granules in stages of digestion. Spherical aggregates of ribosome-like particles may be seen. Golgi complexes seem to produce both a nonordered fibrous material and an electron dense vesicle. Only the latter appears to bleb off from the Golgi complex. X-ray microanalysis demonstration of silicon in Golgi vesicles and in some dense vesicles suggests that the fibrous component of the cisternae may take up and concentrate silica to form the electron-dense component of the vesicles. Membrane bound siliceous crystals are often seen adjacent to the Golgi, suggesting either a Golgi origin or platelet formation in vesicles after release from the Golgi complex. Both electron-dense bodies and siliceous platelets are released from the cell by a process similar to apocrine secretion and may be seen outside the cell in route to the shell during shell morphogenesis. Shell development involves fusion of electron-dense bodies to form a matrix, positioning of siliceous platelets in this matrix parallel to the shell surface, and development of a system of matrix chambers. A particulate glycoconjugate is released to the shell surface upon rupture of the matrix chamber.

No evidence for a centriole or centriolar derivative is obtained. Nine striated coarse fibres and the two central fibres of the axoneme extend into the base of the implantation fossa. The axonemal doublet system is disrupted in the neck region. There are two fibrous accessory structures located between the central doublet and the striated coarse fibres. PMID- 30301288 TI - Ultrastructure of the vasa deferentia of the mediterranean flour moth. AB - Each vas deferens of the Mediterranean flour moth, Anagasta kuehniella (Zeller), consists of a short swollen portion immediately below the testis, another swollen portion that forms a seminal vesicle, and an elongate lower portion that empties into one arm of the ductus ejaculatoris duplex. Three types of epithelial cells occur sequentially. Phagocytic cells that engulf debris from the testis form the anterior two-thirds of the first swollen portion. Tall secretory cells form the distal third of the first swollen region and extend to the seminal vesicles. The secretory cells surround a slit-like lumen and appear to function as a valve between the two swollen regions. Many membrane-enclosed secretory granules are stored at the apical ends of the cells and are released into the lumen together with small amounts of the surrounding cytoplasm. The granules remain intact while they are in the male tract. A second type of secretory cell forms the walls of the seminal vesicles and the lower vasa deferentia. These cells produce secretory granules whose contents become dispersed through the semen. PTA-chromic acid staining indicates that the seminal plasma has a high glycoprotein content. A thin muscle layer is basal to the epithelial cells. Both apyrene and eupyrene sperm undergo some development in the vasa deferentia. The epithelial cells, muscle, and stored sperm all undergo extensive changes with age. PMID- 30301289 TI - The ultrastructure of the hepatopancreatic caeca of Gammarus minus (crustacea, amphipoda). AB - The hepatopancreatic caeca of the freshwater amphipod Gummarus minus are four tapered blind pouches lined with a simple columnar epithelium bearing an apical surface of regular microvilli and resting on a basement membrane. This epithelium is enclosed by a tonic, striated muscularis. Each caecum consists of three regions. The distal zone is formed of embryonic cells having a high nuclear to cytoplasmic ratio and giving rise to the other cell types. The second or differentiation zone consists of regular tall columnar cells of two morphological types:(1) light staining R-cells which have a large number of lipid droplets and few Golgi bodies; (2) basophilic F-cells which have numerous distended Golgi bodies. The more proximal secretory zone forms the majority of each diverticulum. This mature zone is formed from R-cells and large, basophilic, vacuolated B-cells which differentiate from F-cells. The secretory cell sequence appears to be E cell - F-cell - B-cell with secretion being apocrine in nature. The exact relationship of Rcells to the other cell types is questionable, but the R-, F - and B-cells all appear to be able to absorb and store nutrients. Within the Malacostraca the hepatopancreatic epithelium of Amphipoda more closely approximates that of Decapoda than that of the Isopoda. PMID- 30301290 TI - Cytochemical observations of larval development in Eunapius fragilis (Leidy): Porifera; spongillidae. AB - Freshwater sponges of the family Spongillidae reproduce sexually through formation of a parenchymula larva. The cytochemical characteristics of parenchymula larval metamorphosis - beginning with the blastula and terminating with the motile escape stage - for the spongillid Eunapius fragilis (Leidy) have been defined using both absorption and fluorescent cytochemical methods, particularly those demonstrating protein end-groups. Morphogenesis of the parenchymula larva of E. fragilis involves the interrelated processes of cytodifferentiation and mobilization of reserve materials. Larval development has been categorized into five stages, from blastula (stage I) through the escape stage (stage V). Parenchymula development is characterized by morphogenetic precocity, a fact influencing the rate of mobilization of cytoplasmic reserves, cytodifferentiation, and the fate of individual cell types. With attainment of the stage V parenchymula, the larva is, essentially, a mobile adult sponge exhibiting flagellated chambers, canal systems, a well defined connective tissue stroma, a diverse cell population consisting of specialized elements and a totipotent archeocyte reserve, and a terminal epitheliocyte line. The present study recognizes differences in development within the spongillids as well as within more remote poriferan taxa - emphasizing the need for detiled understanding of particular processes in individual species before proposing major generalizations about development in this ancient but evolutionally specialized group. PMID- 30301291 TI - Dynamics and acoustical radiation of Porichthys notatus' swim bladder system. AB - The swimbladder system of the plainfin midshipman consists of a gas-filled bladder and two intrinsic sonic muscles which are attached to the bladder at opposite sides. An experimental and analytical study was conducted to define the physical characteristics of this dynamic system, and to relate these characteristics to radiated acoustical pressure pulses. Results indicate that the system has two degrees of freedom, being comprised of two inertial, stiffness and damping components; the first and second mode components of a 23.1-centimeter midshipman are 0.002 and 0.019 kg (inertial) 2130 and 106,000 newtons per meter (stiffness) and 0.25 and 0.10 (damping) respectively. This system is excited by the sonic muscle forcing function which equals ?documentclass{article}?pagestyle{empty}?begin{document}$ 0.00236{?rm}?sin ?frac{{2?pi {?rm t}}}{{0.0045{?rm}?sec}}{?rm newtons}. $?end{document} Two system frequency response peaks were observed; the first was 110 hertz, at the flat section next to the sonic muscle, and was very near the repetition frequency of the sonic muscle pulses; the second was 350 hertz, at the hemispherical section, which was the frequency of the acoustical pressure pulse. These phenomena describe a dynamical system closely "tuned" to its forcing function, and a system which is highly responsive to acoustical pressure pulses radiated by neighboring midshipmen. The acoustical pressure pulse coincides in wave form with the hemispherical bladder wall acceleration. PMID- 30301292 TI - Fine structure of an elongated dorso-ventrally compressed echinoderm (holothuroidea) spermatozoon. AB - The spermatozoon of Cucumaria pseudocurata is unique among those of the echinoderms in that it is tabloid in shape, i.e., elongated and dorsoventrally compressed. The sperm consists of a dorsal surface which contains an extensive striated rootlet-like structure located within a dorsal groove and a ventral surface which contains a medially situated acrosome. A single mitochondrion lies at the base of the nucleus. The flagellum is unusual in that a 9 + 3 tubular arrangement is observed in the mid-tail region. The acrosome consists of an acrosomal granule bounded by a limiting membrane and a surrounding periacrosomal layer. The granule is irregular in shape with the anterior-posterior surfaces flaring out, forming pockets in the periacrosomal material. The ventral granule surface bulges forming a close association with the plasma membrane. The dorsal surface is indented. Ventral to the depression (within the granule) is a small area containing a particulate-fibrous material. To the inside of the granule limiting membrane there is a second membrane-like structure (incomplete) which extends from the anterior-posterior surfaces around the dorsal face of the granule. Dorso-medial to the granule the periacrosomal layer contains a particulate-fibrous region lodged within the granule depression. This material is presumably the precursor of the acrosomal filament. Prominent cytoplasmic folds extend off from the basal flagellar region. The proximal and distal centrioles are situated perpendicular to one another within the mitochondrion. Centriolar satellite materials are associated with both centrioles. Toward the base of the tail the satellite of the distal centriole consists of nine radiating arms extending at an angle of 45 degrees to the axis of the centriole. Each arm terminates in a dense thickening. The striated rootlet extends anteriorly from the distal centriole to just below the level of the acrosome. PMID- 30301293 TI - External morphology of antennae and their sense organs in the roach Gromphadorhina brunneri (Blattoidea: Dictyoptera). AB - The antennae and their sense organs in nymphs and adult roaches of Gromphadorhina brunneri, were investigated and described. The number of segments and sensillae of the nymphal antennae depend on the developmental stage. Sexual dimorphism is pronounced. Males have longer antennae than females as well as an abundance of especially long sensory hairs (long wavy hairs), which are probably responsible for the perception of female sex pheromones. They also have more thin-walled sensory hairs, for instance, sensilla trichodea. On a morphological basis the sensillae of Gromphadorhina brunneri, were named and classified. Long wavy hairs and large sensory hairs appear to be present also in a related species, G. portentosa, but are lacking in others. Their distribution on the antennae varies greatly from that in G. portentosa but their structure varies only slightly. These two types of sense organs are considered to be specialized forms of sensilla chaetica. They are contact chemoreceptors, as are two other types of sensilla chaetica. Furthermore, thin-walled chemoreceptors are present, such as sensilla trichodea, sensilla basiconica, sensilla coeloconica and a typical mechanoreceptor, the sensillum campaniformium. PMID- 30301294 TI - An ultrastructural study of byssus stem formation in Mytilus californianus. AB - In Mytilus californianus, root lamellae of the byssus stem are formed by two morphologically distinct exocrine cell types. Type 1 cells contain large ellipsoid granules which are ultrastructurally identical to those of the collagen gland associated with byssus thread formation: these granules are secreted only at the base of the stem generator. Type 2 cells contain small cylindroid granules which are secreted only from the lateral surfaces of generator septa. The resultant matrix is biphasic because the two secretions are incompletely mixed. Lamellar sheets of matrix are propelled outward by the action of cilia and are molded into a cylinder at the neck region of the stem. However, the stem retains a lamellar pattern. Byssus threads are attached to the stem by flattened rings formed from thread material which is secreted into the cervical crevice surrounding the neck. The microanatomy of the stem forming region is described and a new term, "stem generator," is proposed for this organ. PMID- 30301295 TI - A reconsideration of the phylogeny of the tetrapod heart. AB - After dissecting a variety of vertebrate hearts and extensively reviewing the literature, I have drawn some conclusions concerning the phylogeny of the tetrapod heart that differ from commonly expressed viewpoints in the literature. It is probable that the absence of an interventricular septum in amphibians is a primitive feature (rather than representing a loss). The complete interventricular septum of crocodilians and birds probably evolved primarily from the major horizontal septum of the typical (noncrocodilian) reptilian heart, with a smaller part representing a new development. The interventricular septum of mammals probably also evolved primarily from the reptilian horizontal septum. There is no reason to assume that the mammalian heart and aortic arches evolved directly from a pre-reptilian stage, as is often assumed. The evidence upon which these conclusions are based is given. PMID- 30301296 TI - A comparative study of the chemical defensive system of tenebrionid beetles III. Morphology of the glands. AB - The morphology of the abdominal defensive glands and associated structures of 115 species of tenebrionid beetles was studied on KOH cleared material. The glands and reservoirs of all Tenebrionidae are homologous and evolved as a pair of sacs from the intersegmental membrane between sternites VII and VIII. On the basis of reservoir morphology and secretory cell tubule termination, seven provisional gland types were established. Several of the types include species from several tribes, and several tribes contain several gland types, indicating possible incongruencies between the taxonomy and phylogeny of the family. Morphological trends in the evolution of the glands include: increase of reservoir capacity, constriction of the proximal portion of the sacs into distinct exit ducts, release of secretion by exuding or spraying rather than everting, and concentration of the secretory cell tubule terminations into restricted fields, collecting ducts or ampullae. The morphology of the glands of 58 species is illustrated and the results are discussed in light of the current taxonomy of the Tenebrionidae. PMID- 30301297 TI - A study of the fine structure of the accessory muscle of the horseshoe crab, Tachypleus gigas. AB - The accessory muscle of the walking leg of the horseshoe crab, Tachypleus gigas, was examined electron microscopically. The muscle fibers vary in size but are small in diameter, when compared with other arthropod skeletal muscles. They are striated with A, I, Z and poorly defined H bands. The sarcomere length ranges from 3-10 MUm with most sarcomeres in the range of about 6 MUm. The myofilaments are arranged in lamellae in larger fibers and less well organized in the smaller ones. Each thick filament is surrounded by 9-12 thin filaments which overlap. The SR is sparse but well organized to form a fenestrated collar around the fibrils. Individual SR tubules are also seen among the myofibrils. Long transverse tubules extend inward from the sarcolemma to form dyads or triads with the SR at the A-I junction. Both dyads and triads coexist in a single muscle fiber, a feature believed to have evolutionary significance. The neuromuscular relationship is unique. In the region of synaptic contact, the sarcolemma is usually elevated to form a large club-shaped structure containing no myofilaments and few other organelles. The axons or axon terminals and glial elements penetrate deep into the club-shaped sarcoplasm and form synapses with the fiber. As many as 13 terminals have been observed within a single section. Synaptic vesicles of two types are found in the axon terminals. PMID- 30301298 TI - Chelonian mental glands. AB - A survey of 69 of the 74 currently recognized chelonian genera revealed that 21 genera in three families (Emydidae, Platysternidae and Testudinidae) possess paired integumentary glands or gland vestiges in the anterior throat skin. These glands are here termed mental glands; they are holocrine and may be classified morphologically as follows: Class I mental glands are large, complex, multilobed, have specialized ducts, and are found only in the genus Gopherus: Class II mental glands are small, simple sacklike invaginations containing secretory cells or keratinizing cells. The structure of Class II glands varies from distinctive and saccular to shallow keratinized invaginations having no glandular tissue; they are found only in the families Platysternidae and Emydidae. Mental glands occur in 17 of the 22 genera in the subfamily Batagurinae (sensu McDowell, 64); only 2 of 9 genera in the subfamily Emydinae have these glands. The taxonomic occurrence of mental glands suggests that they are primitive structures. The loss of mental glands in most emydines is interpreted as a subfamilial trend toward integumentary simplification. PMID- 30301299 TI - A simplified placenta-like system for the transport of extraembryonic nutrients during embryogenesis of Bugula neritina (bryozoa). AB - Embryos of the marine cheilo-ctenostome bryozoan Bugula neritina undergo a marked increase in volume (about 500-fold) during embryogenesis while being retained in a brood chamber. Previous morphological studies indicate that shortly after transfer of the zygote to the brood chamber, the epithelium of the maternally derived portion of the brood chamber, the ooecial vesicle, differentiates in regions adjacent to the embryonary space from a squamous to a columnar form suggesting that the parent is involved as a source of extraembryonic nutrients required for the extensive growth of the embryo. Results of the present ultrastructural study indicate that hypertrophy of the epithelial cells occurs only in that region of the ooecial vesicle which opposes the embryo, that differentiation (and subsequent regression) of the lining are predictable events correlated with the onset (and termination) of embryonic growth, and that hypertrophied cells are well equipped for the synthesis and transport of macromolecular materials across the vesicle wall to the developing embryo. Further, that portion of the embryo's ectoderm (the presumptive metasomal sac) in contact with this hypertrophied epithelium is morphologically specialized for the uptake of nutrients. Finally, shortly before release of the larva, this intimate association of the metasomal sac tissue and the hypertrophied ooecial vesicle lining epithelium is terminated by invagination of the sac and atrophy of the lining. PMID- 30301300 TI - The Relationship between Plasma Oxytocin Levels and Social Anxiety Symptoms. AB - OBJECTIVE: The pathophysiology of social anxiety disorder (SAD) is not yet well understood, but previous research has suggested that oxytocin is associated with social behavior and may play a role in human anxiety states and anxiety-related traits. The aim of this study was to investigate the possible relationship between social anxiety symptoms and plasma oxytocin levels. METHODS: Twenty-three male patients with SAD and 28 healthy male controls participated in this study. All participants were assessed using the Mini International Neuropsychiatric Interview (MINI) and the Liebowitz Social Anxiety Scale (LSAS). Multivariate regression analysis was performed to identify associations between plasma oxytocin levels and SAD. RESULTS: In multiple regression models, after controlling for age and years of education, we found that higher oxytocin levels were significantly associated with higher total LSAS scores (R2 =0.157, coefficient=0.145, 95% CI=-0.0005-0.291, p=0.051) and fear subscale scores (R2 =0.134, coefficient=0.083, 95% CI=0.007-0.159, p=0.034) in the SAD group. CONCLUSION: In this study, increased plasma oxytocin levels were associated with higher social anxiety symptoms among SAD patients, but not among controls. This might be because among SAD patients, higher oxytocin (OT) secretion is an insufficient compensatory attempt to reduce social anxiety symptoms.

AB - OBJECTIVE: In this study, we aimed to develop a model predicting individuals with suicide ideation within a general population using a machine learning algorithm. METHODS: Among 35,116 individuals aged over 19 years from the Korea National Health & Nutrition Examination Survey, we selected 11,628 individuals via random down-sampling. This included 5,814 suicide ideators and the same number of non suicide ideators. We randomly assigned the subjects to a training set (n=10,466) and a test set (n=1,162). In the training set, a random forest model was trained with 15 features selected with recursive feature elimination via 10-fold cross validation. Subsequently, the fitted model was used to predict suicide ideators in the test set and among the total of 35,116 subjects. All analyses were conducted in R. RESULTS: The prediction model achieved a good performance [area under receiver operating characteristic curve (AUC)=0.85] in the test set and predicted suicide ideators among the total samples with an accuracy of 0.821, sensitivity of 0.836, and specificity of 0.807. CONCLUSION: This study shows the possibility that a machine learning approach can enable screening for suicide risk in the general population. Further work is warranted to increase the accuracy of prediction.

AB - OBJECTIVE: Post weanling isolation-reared (IR) rats are featured with depressive phenotype, yet its mechanism is not clearly defined particularly in terms of the involvement of central 5-HT1A receptors. The present study aims to examine the effects of 5HT1A activation on forced swim test (FST) in IR rats following 5-HT depletion. METHODS: Social control (SOC) and IR rats received an intracerebraoventricular (ICV) injection of 5-HT depletion agent, 5,7-DHT. 14 days after the surgery, rats were assessed their performance in FST with or without the challenge with a 5-HT1A agonist, 8-OH-DPAT. Rats were then sacrificed for analyzing their 5-HT tissue levels and the expressions of their 5-HA1A receptors in prefrontal cortex (PFC), hippocampus (HPX), and amygdala (AMY). RESULTS: 5,7-DHT decreased the tissue concentration of 5-HT in both IR and SOC rats. IR rats were more immobile and less sensitive to the lesion-induced immobility, however this effect was reversed by acute challenge of 8-OH-DPAT. 5,7 DHT lesion increased the expression of PFC 5-HT1A receptors. CONCLUSION: The integrity of central 5-HT system is developmentally crucial for the 5-HT1A relevant depression profile in rats of social isolation. PMID- 30301303 TI - A Novel Bio-Psychosocial-Behavioral Treatment Model of Panic Disorder. AB - To conceptualize a novel bio-psychosocial-behavioral treatment model of panic disorder (PD), it is necessary to completely integrate behavioral, psychophysiological, neurobiological, and genetic data. Molecular genetic research on PD is specifically focused on neurotransmitters, including serotonin, neuropeptides, glucocorticoids, and neurotrophins. Although pharmacological interventions for PD are currently available, the need for more effective, faster acting, and more tolerable pharmacological interventions is unmet. Thus, glutamatergic receptor modulators, orexin receptor antagonists, corticotrophin releasing factor 1 receptor antagonists, and other novel mechanism-based anti panic therapeutics have been proposed. Research on the neural correlates of PD is focused on the dysfunctional "cross-talk" between emotional drive (limbic structure) and cognitive inhibition (prefrontal cortex) and the fear circuit, which includes the amygdala-hippocampus-prefrontal axis. The neural perspective regarding PD supports the idea that cognitive-behavioral therapy normalizes alterations in top-down cognitive processing, including increased threat expectancy and attention to threat. Consistent with the concept of "personalized medicine," it is speculated that Research Domain Criteria can enlighten further treatments targeting dysfunctions underlying PD more precisely and provide us with better definitions of moderators used to identify subgroups according to different responses to treatment. Structuring of the "negative valence systems" domain, which includes fear/anxiety, is required to define PD. Therefore, targeting glutamate- and orexin-related molecular mechanisms associated with the fear circuit, which includes the amygdala-hippocampus-prefrontal cortex axis, is required to define a novel bio-psychosocial-behavioral treatment model of PD. PMID- 30301304 TI - Smart Stress Care: Usability, Feasibility and Preliminary Efficacy of Fully Automated Stress Management Application for Employees. AB - OBJECTIVE: We developed a fully automated smartphone-based stress management application and explored its usability, potential feasibility, and preliminary efficacy for stress management in Korean employees. METHODS: Healthy employees working in large public enterprises were enrolled. Participants used our automated stress management application for four weeks. With the application, they monitored their stress level and life style factors. Personalized stress management techniques, including psychoeducation and cognitive behavioral technique, were also provided based on their stress level and lifestyle pattern. In 2014, additional relaxation techniques were incorporated. Participants' mental health status and lifestyle pattern were self-assessed at baseline and at 4 weeks after using the application. RESULTS: A total of 68 subjects were recruited. The application generally received high satisfaction rating. After the intervention, perceived stress level was significantly decreased, both in 2013 and 2014 (BEPSI K score pre. vs. post. 14.27 vs. 11.00, F=12.49, p=0.001 in 2013; 12.05 vs. 10.00, F=17.18, p<0.001). In 2014, depression symptom severity was also significantly decreased (CES-D score pre- vs. Post-, 17.66 vs. 11.95, F=9.76, p=0.004). The effects were more significant in females and in those <35 years. CONCLUSION: Our fully automated stress management application is acceptable and usable, showing preliminary efficacy for reducing employees' stress levels. PMID- 30301305 TI - How Game Addiction Rates and Related Psychosocial Risk Factors Change Within 2 Years: A Follow-Up Study. AB - OBJECTIVE: Prospective data of risky online gamers in Turkey is missing. Therefore, we aimed to investigate the change in gaming behaviors and addiction rates of Travian players within two years to search diagnostic stability of internet gaming disorder and some psychosocial risk factors. METHODS: 110 responders completed the whole questionnaire package including 21-item Game Addiction Scale (GAS), Satisfaction with Life Scale (SLS), Rosenberg Self-Esteem Scale (RSES), and Multi-dimensional Scale of Perceived Social Support (MSPSS). A hierarchical linear modeling approach was followed to test the linear change in game addiction scores of the participants from 2013 to 2015. RESULTS: GAS scores of gamers significantly decreased within two years (p=0.026). MSPSS scores significantly and negatively associated with GAS scores (p<0.001) and the negative association of time remained significant (p=0.035). Decrement in the MSPSS scores in two years was associated with increment in GAS scores. 9 (90%) of 10 participants with internet gaming disorder according to monothetic format and 26 (52%) of 50 participants with internet gaming disorder according to polythetic format were found to not to meet the diagnosis in the follow-up. 33 out of all participants reported that they were not playing any online games for at least last 6 months. CONCLUSION: Social support seems to be a protective factor for game addiction and diagnosis of internet gaming disorder has low temporal stability among Travian players in Turkey. PMID- 30301306 TI - Reliability and Validity of the Korean Version of Health Anxiety Questionnaire. AB - OBJECTIVE: Health anxiety can be defined by concern about health in the absence of a pathology. The Health Anxiety Questionnaire (HAQ) based on the cognitive behavioral model can be useful for evaluating the severity and the structure of health anxiety. This study aims to verify the reliability and validity of Korean version of HAQ (K-HAQ). METHODS: For reliability, test-retest reliability and internal consistency were analyzed. For construct validity, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted. Receiver Operating Characteristic (ROC) analysis was performed to identify the optimal cut off score. RESULTS: Cronbach's alpha was 0.92, and r value of test-retest reliability was 0.84. In the EFA, 4- and 5-factor model showed cumulative percentile of variance of 60% or more. In the CFA, the 4-factor model was found to be the most appropriate and simplest (chi2 =397.33, df=187, CFI=0.909, TLI=0.888, RMSEA=0.077). In the ROC analysis, the cut-off score was 20 points. CONCLUSION: It is expected that K-HAQ can be helpful to evaluate the severity of health anxiety and make therapeutic plans because KHAQ can help explore the cognitive, emotional, and behavioral structure of health anxiety by each factor. PMID- 30301307 TI - Does Psychodrama Affect Perceived Stress, Anxiety-Depression Scores and Saliva Cortisol in Patients with Depression? AB - OBJECTIVE: Little is known about the effects of psychodrama group therapy on the level of stress, anxiety and depression of the group members, and the biological markers of stress. The aim of this study test cortisol level as a biological reflection of some mental characteristics gained by the psychodrama method in coping with stress. METHODS: Depressive patients aged between 18 and 65 years, who diagnosed with depression according to DSM-5, without psychiatric comorbidity, who do not use drugs and were available for psychodrama were enrolled into the study. These patients were evaluated using the Perceived Stress Scale, State-Trait Anxiety Inventory and Beck Depression Inventory. In order to observe the circadian rhythm of cortisol, samples were collected from the participants before lunch, before dinner and before going to sleep on the day before psychodrama and on the 0, 15th, and 30th minutes after awakening in the morning of the psychodrama day; as well as just before and after the psychodrama session. Saliva cortisol level just before the initial session of psychodrama group therapy was compared with the saliva cortisol level just after the last psychodrama session at the end of 16 weeks. RESULTS: Statistically significant difference was determined between the scores of perceived stress scale, STAI-1, STAI-2, beck depression inventory and salivary cortisol level before and after psychodrama session. There was significant decrease in both the scale scores and salivary cortisol after vs. before psychodrama. CONCLUSION: This results is important as it shows the biological aspect of clinical improvement. Further studies would provide us with better understanding of the effects of psychodrama group psychotherapy on depressive mood and biological projections by means of short-term and long-term follow-up studies. PMID- 30301308 TI - Mediating Effect of Internet Addiction on the Association between Resilience and Depression among Korean University Students: A Structural Equation Modeling Approach. AB - OBJECTIVE: This study examined the mediating role of internet addiction in the association between psychological resilience and depressive symptoms. METHODS: 837 Korean university students completed a survey with items of demographic information, Connor-Davidson Resilience Scale (CD-RISC), Internet Addiction Test (IAT), and Patient Health Questionnaire (PHQ-9) in 2015. The complex associations among psychological resilience, internet addiction, and depressive symptoms were delineated using structural equation models. RESULTS: In the most parsimonious model, the total effect and indirect effect of resilience on depressive symptoms via internet addiction, were statistically significant. The goodness of fit of the measurement model was satisfactory with fit indices, normed fit index (NFI) of 0.990, non-normed fit index (NNFI) of 0.997, comparative fit index (CFI) of 0.998, root mean square error (RMSEA) of 0.018 (90%CI=0.001-0.034); and Akaike Information Criterion (AIC) of -21.049. CONCLUSION: The association between psychological resilience and depressive symptoms was mediated by internet addiction in Korean university students. Enhancement of resilience programs could help prevent internet addiction and reduce the related depression risks. PMID- 30301309 TI - Spatial Learning and Memory Using a Radial Arm Maze with a Head-Mounted Display. AB - OBJECTIVE: A radial arm maze (RAM) is an essential tool for assessing spatial learning and memory. Although this tool is widely used to study deficits in spatial memory in animal models, it has several restrictions that prevent its adaptation to human research and training. Therefore, we developed a head-mounted display RAM (HMD-RAM) program for humans and verified its validity by comparing it to the results obtained by previous RAM studies. We also compared the HMD and a flat monitor as experimental devices. METHODS: Forty participants were recruited for the current study (Study 1: 20 participants with the HMD device; Study 2: 20 participants with the flat monitor). They navigated a virtual room as a first-person viewer and used environmental landmarks to remember their spatial position and orientation. The main dependent measures were working memory error, reference memory error, detection time, travel distance, and participant's head movements. To validate the program, participants also conducted neuropsychological assessments and self-reported measures. RESULTS: The results for HMD-RAM tasks were consistent with the results of previous research conducted on animals, and the HMD elicited a higher sense of presence, immersion, and simulator sickness than the flat monitor. According to post-experiment questions on navigation strategy, creating landmarks was important when people were discovering locations in their environment, and an HMD was beneficial for better navigation strategy. CONCLUSION: These results suggest that the HMD-RAM is valuable for estimating spatial learning and memory in humans and may be a useful tool for early diagnosis of deficits in spatial learning and memory, including amnestic mild cognitive impairment and Alzheimer's disease. PMID- 30301310 TI - Comparison of three risk stratification models for non-clear cell renal cell carcinoma patients treated with temsirolimus as first-line therapy. AB - Background/Aims: For metastatic renal cell carcinoma (RCC), various prognostic scoring systems have been developed. However, owing to the low prevalence of nonclear cell RCC, the three most commonly used tools were mainly developed based on patients with clear cell histology. Accordingly, this study applied three prognostic models to Korean non-clear cell RCC patients treated with first-line temsirolimus. Methods: This study analyzed data for 74 patients with non-clear cell RCC who were treated with temsirolimus as the first-line therapy at eight medical centers between 2011 and 2016. The receiver-operating characteristic (ROC) curves for the different prognostic models were analyzed. Results: Twenty seven (36.5%), 24 (32.4%), and 44 patients (59.5%) were assigned to the poor prognosis groups of the Memorial Sloan-Kettering Cancer Center (MSKCC), International Metastatic RCC Database Consortium (IMDC), and Advanced Renal Cell Carcinoma (ARCC) risk stratification models, respectively. All three prognostic models reliably discriminated the risk groups to predict progression-free survival and overall survival (p < 0.001). The area under the ROC curve (AUC) for progression and survival was highest for the ARCC model (0.777; 0.734), followed by the IMDC (0.756; 0.724) and the MSKCC (0.742; 0.712) models. Furthermore, the sensitivity and specificity for predicting progression were highest with the ARCC model (sensitivity 63.6%, specificity 85.7%), followed by the MSKCC (sensitivity 58.2%, specificity 86.5%) and the IMDC models (sensitivity 56.4%, specificity 85.7%). Conclusions: All three prognostic models accurately predicted the survival of the non-clear cell RCC patients treated with temsirolimus as the first-line therapy. Furthermore, the ARCC risk model performed better than the other risk models in predicting survival. PMID- 30301311 TI - Evaluating the Headspace Volatolome, Primary Metabolites, and Aroma Characteristics of Koji Fermented with Bacillus amyloliquefaciens and Aspergillus oryzae. AB - Production of good Koji primarily depends upon the selection of substrate materials and fermentative microflora, which together influence the characteristic flavor and aroma. Herein, we performed comparative metabolomic analyses of volatile organic compounds (VOCs) and primary metabolites for Koji samples fermented individually with Bacillus amyloliquefaciens and Aspergillus oryzae. The VOCs and primary metabolites were analyzed using headspace solid phase microextraction (HS-SPME) followed by gas chromatography time-of-flight mass spectrometry (GC-TOF-MS). In particular, alcohols, ketones, and furans were mainly detected in Bacillus-fermented Koji (Bacillus Koji, BK), potentially due to the increased levels of lipid oxidation. A cheesy and rancid flavor was characteristic of Bacillus Koji, which is attributable to high content of typical 'off-flavor' compounds. Furthermore, the umami taste engendered by 2 methoxyphenol, (E,E)-2,4-decadienal, and glutamic acid was primarily detected in Bacillus Koji. Alternatively, malty flavor compounds (2-methylpropanal, 2 methylbutanal, 3-methylbutanal) and sweet flavor compounds (monosaccharides and maltol) were relatively abundant in Aspergillus-fermented Koji (Aspergillus Koji, AK). Hence, we argue that the VOC profile of Koji is largely determined by the rational choice of inocula, which modifies the primary metabolomes in Koji substrates, potentially shaping its volatolome as well as the aroma characteristics. PMID- 30301312 TI - Analysis of the Microbiota on Lettuce (Lactuca sativa L.) Cultivated in South Korea to Identify Foodborne Pathogens. AB - Lettuce (Lactuca sativa L.) is a major ingredient used in many food recipes in South Korea. Lettuce samples were collected during their maximum production period between April and July in order to investigate the microbiota of lettuce during different seasons. 16S rRNA gene-based sequencing was conducted using Illumina MiSeq, and real-time PCR was performed for quantification. The number of total bacterial was greater in lettuce collected in July than in that collected in April, albeit with reduced diversity. The bacterial compositions varied according to the site and season of sample collection. Potential pathogenic species such as Bacillus spp., Enterococcus casseliflavus, Klebsiella pneumoniae, and Pseudomonas aeruginosa showed season-specific differences. Results of the network co-occurrence analysis with core genera correlations showed characteristics of bacterial species in lettuce, and provided clues regarding the role of different microbes, including potential pathogens, in this microbiota. Although further studies are needed to determine the specific effects of regional and seasonal characteristics on the lettuce microbiota, our results imply that the 16S rRNA gene-based sequencing approach can be used to detect pathogenic bacteria in lettuce. PMID- 30301314 TI - A Novel Approach for Sericin-Conjugated Silver Nanoparticle Synthesis and Their Potential as Microbicide Candidates. AB - Silver nanoparticles have been widely applied for biomedical areas owing to their potent antiviral and antibacterial activities. Synthesis of silver nanoparticles using biomacromolecules is more efficient, environment-friendly, and cost-saving compared with the traditional approach. In this paper, a novel approach was developed to establish a reaction system with Ag+-BH4--sericin to synthesize silver nanoparticles conjugated to sericin (AgNPs-Sericin). Sericin could be as a good dispersant and stabilizing agent, which is able to modify nanoscaled AgNPs, the average diameter of which was only 3.78 +/- 1.14nm prepared in a 0.3 mg/ml sericin solution. The characterizations of the AgNPs-Sericin were determined by FTIR, thermogravimetry, and XRD analyses. The results showed that the synthesized AgNPs conjugated with sericin as organic phase. Via SAED and XRD analysis, we showed that these AgNPs formed polycrystalline powder with a face-centered cubic structure of bulk metals. Moreover, we investigated the antiviral and antibacterial activities of AgNPs-Sericin, and the results showed that AgNPs Sericin exhibited potent anti-HIV-1 activity against CCR5-tropic and CXCR4-tropic strains, but no significant cytotoxicity was found toward human genital epithelial cells compared with free silver ions, which are accepted as a commonly used potent antimicrobial agent. Moreover, its antibacterial activity was determined via flow cytometry. The results showed that AgNPs-Sericin could suppress gram-negative (E. coli) and gram-positive (S. aureus) bacteria, but more was potent for the gram-negative one. We concluded that our AgNPs-Sericin could be a potential candidate as a microbicide or antimicrobial agent to prevent sexually transmitted infections. PMID- 30301313 TI - Anti-Angiogenesis Effects Induced by Octaminomycins A and B against HUVECs. AB - In the course of studies to discover natural products with anti-angiogenic properties, two cyclic octapeptides, octaminomycins A (1) and B (2), were isolated from the cultures of Streptomyces sp. RK85-270. Octaminomycins suppressed the vascular endothelial growth factor (VEGF)-induced proliferation, adhesion, tube formation, migration, and invasion of HUVECs. Anti-angiogenic activity was futher confirmed in vivo by the chicken chorioallantoic membrane assay. We also identified that 1 and 2 inhibited the phosphorylation of VEGF receptor 2, AKT, and ERK1/2 and the expression and activities of MMP-2 and MMP-9. These results suggest that 1 and 2 may serve as potential scaffolds for the development of therapeutic agents to angiogenesis-dependent diseases. PMID- 30301315 TI - Generation and Characterization of a Neutralizing Human Monoclonal Antibody to Hepatitis B Virus PreS1 from a Phage-Displayed Human Synthetic Fab Library. AB - The hepatitis B virus (HBV) envelope contains small (S), middle (M), and large (L) proteins. PreS1 of the L protein contains a receptor-binding motif crucial for HBV infection. This motif is highly conserved among 10 HBV genotypes (A-J), making it a potential target for the prevention of HBV infection. In this study, we successfully generated a neutralizing human monoclonal antibody (mAb), 1A8 (IgG1), that recognizes the receptor-binding motif of preS1 using a phage displayed human synthetic Fab library. Analysis of the antigen-binding activity of 1A8 for different genotypes indicated that it can specifically bind to the preS1 of major HBV genotypes (A-D). Based on Bio-Layer interferometry, the affinity (KD) of 1A8 for the preS1 of genotype C was 3.55 nM. 1A8 immunoprecipitated the hepatitis B virions of genotypes C and D. In an in vitro neutralization assay using HepG2 cells overexpressing the cellular receptor sodium taurocholate cotransporting polypeptide, 1A8 effectively neutralized HBV infection with genotype D. Taken together, the results suggest that 1A8 may neutralize the four HBV genotypes. Considering that genotypes A-D are most prevalent, 1A8 may be a neutralizing human mAb with promising potential in the prevention and treatment of HBV infection. PMID- 30301316 TI - Regulation of AKT Activity by Inhibition of the Pleckstrin Homology Domain PtdIns(3,4,5)P3 Interaction Using Flavonoids. AB - The serine-threonine kinase AKT plays a pivotal role in tumor progression and is frequently overactivated in cancer cells; this protein is therefore a critical therapeutic target for cancer intervention. We aimed to identify small molecule inhibitors of the pleckstrin homology (PH) domain of AKT to disrupt binding of phosphatidylinositol-3,4,5-trisphosphate (PIP3), thereby downregulating AKT activity. Liposome pulldown assays coupled with fluorescence spectrometry were used to screen flavonoids for inhibition of the AKT PH-PIP3 interaction. Western blotting was used to determine the effects of the inhibitors on AKT activation in cancer cells, and in silico docking was used for structural analysis and optimization of inhibitor structure. Several flavonoids showing up to 50% inhibition of the AKT PH-PIP3 interaction decreased the level of AKT activation at the cellular level. In addition, the modified flavonoid showed increased inhibitory effects and the approach would be applied to develop anticancer drug candidates. In this study, we provide a rationale for targeting the lipid-binding domain of AKT, rather than the catalytic kinase domain, in anticancer drug development. PMID- 30301317 TI - Trends in medical disputes involving anesthesia in the period July 2009-June 2018: an analysis of the Korean Society of Anesthesiologists database. AB - Background: To identify trends in injuries and substandard care associated with anesthesia, we analyzed the Korean Society of Anesthesiologists database, which includes anesthesia-related case files from July 2009 to June 2018. Methods: Case characteristics, injuries, and outcomes were compared between the first part (July 2009-June 2014, n = 105) and the second part (July 2014-June 2018, n = 92) of the analyzed time period. Results: Overall, 132 cases resulted in death. The proportion of fatal cases for sedation was similar to that for general anesthesia (66.2% vs. 76.3%). The proportion of cases with permanent injury or death decreased significantly in the second part of the period compared with the first part (76.1% vs. 93.3%, P = 0.002). With a growing trend in the proportion of sedation cases, a similar number of sedation and general anesthesia cases were referred during the overall period (77 and 76 cases, respectively). Propofol based regimens remained the dominant sedation method (89.7% in the first part vs. 78.9% in the second part). A respiratory origin was identified as the most common adverse event in cases of permanent injury or death (98/182, 53.8%). Specifically, eight and five cases with permanent injury Sor death were related to local anesthetic systemic toxicity (LAST) and beach-chair positioning for shoulder surgery, respectively. Conclusions: Despite the decreasing trend in injury severity, several characteristic injury profiles were identified: lack of vigilance in propofol-based sedation, neurological injuries related to the beach chair position, and LAST occurring during tumescent anesthesia or brachial plexus block.

AB - Pseudomonas tolaasii 6264 is a representative strain that causes bacterial blotch disease on the cultivated oyster mushroom, Pleurotus ostreatus. Bacteriophages are able to sterilize the pathogenic P. tolaasii strains and therefore, they can be applied to make a disease-free cultivation farm, known as "phage therapy". For successful phage therapy, the characterization of phage-resistant strains is necessary, since they are frequently induced from the original pathogenic bacteria in the presence of phages. When 10 phages were incubated with P. tolaasii 6264, their corresponding phage-resistant strains were obtained. In this study, changes in pathogenic, genetic, and biochemical characteristics as well as the acquired phage resistance of these strains were investigated. In the phylogenetic analyses, all phage-resistant strains were identical to the original parent strain based on the sequence comparison of 16S rRNA genes. When various phage-resistant strains were examined by three different methods, pitting test, white line test, and hemolytic activity, they were divided into three groups: strains showing all positive results in three tests, two positive in the first two tests, and all negative. Nevertheless, all phage-resistant strains showed that their pathogenic activities were reduced or completely loss. PMID- 30301323 TI - Heterologous expression and characterization of a laccase from Laccaria bicolor in Pichia pastoris and Arabidopsis thaliana. AB - Laccases can oxidize a variety of phenolic and non-phenolic substrates including synthetic dyes. In this research, a laccase gene Lcc9 from Laccaria bicolor was chemically synthesized and optimized to heterogeneous expression in Pichia pastoris and Arabidopsis thaliana. The properties of recombinant laccase expressed by P. pastoris were investigated. The laccase activity was optimal at 3.6 pH and 40 degrees C. It exhibited Km and Vmax values of 0.565 mmol l-1 and 1.51 MUmol l-1 min-1 for ABTS respectively. As compared with untransformed control plants, the laccase activity in crude extracts of transgenic lines exhibited a 5.4 to 12.4-fold increased. Both laccases expressed in transgenic P. pastoris or A. thaliana could decolorize crystal violet. These results indicated that L. bicolor laccase gene may be transgenically exploited in fungi or plants for dye decolorization. PMID- 30301324 TI - Design, optimization and verification of 16S rRNA oligonucleotide probes of Fluorescence in-situ hybridization for targeting Clostridium spp. and Clostridium kluyveri. AB - Fluorescence in-situ hybridization (FISH) is a common and popular method to investigate microbial communities in natural and engineered environments. In this study, two specific 16S rRNA-targeted oligonucleotide probes CLZ and KCLZ were designed and verified to quantify the genus Clostridium and the species Clostridium kluyveri. The optimal concentration of hybridization buffer solution for both probes CLZ and KCLZ was 30% (w/v). The specificity of the designed probes was high by using pellets from the pure reference strains. Feasibility was tested using the samples of Luzhou-flavor liquor manufacturing cellar. The effectiveness of detecting target cells appears to vary widely in different environments. In pit mud, the detection effectiveness of the target cell by probe CLZ and KCLZ was 49.11% and 32.14%, respectively. The quantitative analysis by FISH technique of microbes in pit mud and fermented grains showed consistency with the results detected by qPCR and PCR-DGGE techniques, which showed that the probes CLZ and KCLZ were suitable to analyze the biomass of Clostridium spp. and C. kluyveri during liquor fermentation. Therefore, this study provides a method for quantitative analysis of Clostridium spp. and C. kluyveri and monitoring their community dynamics in microecosystems.

AB - Enhanced application of solid-state fermentation (SSF) in industrial production and the influence of SSF of Rhizopus K1 on glucoamylase productivity were analyzed using flat band method. A growth model was implemented through SSF of Rhizopus K1 in this experiment, and spectrophotometric method was used to determine glucoamylase activity. Results showed that in bran and potato culture medium with 70% moisture in a loose state, MU of mycelium reached to 0.15 h-1 after 45 h of culture in a thermostatic water bath incubator at 30 degrees C. Under a low-magnification microscope, mycelial cells appeared uniform, bulky with numerous branches, and not easily ruptured. The generated glucoamylase activity reached to 55 U/g (dry basis). This study had good utilization value for glucoamylase production by Rhizopus in SSF.

AB - Recent human gut microbiome studies have supported that the genus Bifidobacterium is one of the most beneficial bacteria for human intestinal health. To develop a new probiotic strain for functional food applications, fourteen fecal samples were collected from healthy Koreans and a strain BCBR-583 was newly selected and isolated from a 25-year-old Korean woman's fecal sample using the selective medium for Bifidobacterium. Subsequent fructose-6-phosphate phosphoketolase (F6PPK) test and 16S rRNA gene sequencing analysis of the strain BCBR-583 confirmed that it belongs to B. longum subsp. longum. The stress resistance tests showed that it has oxygen and heat tolerance activities (5- and 3.9-fold increase for 24 h at 60 and 120 rpm, respectively; 78.61 +/- 6.67% survival rate at 45 degrees C for 24 h). In addition, gut environment adaptation tests revealed that this strain may be well-adapted in the gut habitat, with gastric acid/bile salt resistance (85.79 +/- 1.53%, survival rate under 6 h treatments of gastric acid and bile salt) and mucin adhesion (73.72 +/- 7.36%). Furthermore, additional tests including cholesterol lowering assay showed that it can reduce 86.31 +/- 1.85% of cholesterol. Based on these results, B. longum BCBR-583 has various stress resistance for survival during food processing and environmental adaptation activities for dominant survival in the gut, suggesting that it could be a good candidate for fermented food applications as a new probiotic strain.

AB - The objective of this study was to evaluate the magnified endoscopic findings in the diagnosis of follicular lymphoma in the small intestine in comparison with those of intestinal follicular lymphoma and lymphangiectasia. Four patients with follicular lymphoma and 3 with lymphangiectasia in the small intestine were retrospectively analyzed. A prototype magnifying singleballoon enteroscope was used. The findings of the intestinal follicular lymphoma and lymphangiectasia were retrospectively analyzed to determine the magnified endoscopic findings of follicular lymphoma in the small intestine. Opaque white granules were observed in 3 of the 4 patients with follicular lymphoma. Magnified narrow-band imaging (NBI) of the opaque white granules showed stretched microvessels, which had a diminutive tree-like appearance. The remaining patient had no opaque white granules and only displayed whitish villi. Magnified NBI observation of the whitish villi revealed the absence of marginal villus epithelium, which was confirmed by histology. The magnified NBI enteroscopy revealed the diminutive tree-like appearance on the opaque white granules and the absence of marginal villus epithelium of the whitish villi in intestinal follicular lymphoma. These findings may be useful in diagnosing follicular lymphoma. PMID- 30301327 TI - Rates of metachronous adenoma after curative resection for left-sided or right sided colon cancer. AB - Background/Aims: We determined the rates of metachronous colorectal neoplasm in colorectal cancer (CRC) patients after resection for right (R)-sided or left (L) sided cancer. Methods: Consecutive CRC patients who had undergone surgical resection for curative intent in our hospital between 2001 and 2004 were identified. R-sided colonic cancers refer to cancer proximal to splenic flexure whereas L-sided cancers include rectal cancers. Patients were included only if they had a clearing colonoscopy performed either before or within 6 months after the operation. Findings of surveillance colonoscopy performed up to 5 years after colonic resection were included in the analysis. Results: Eight hundred and sixty three CRC patients underwent curative surgical resection during the study period. Three hundred and twenty-seven patients (107 R-sided and 220 L-sided) fulfilled the inclusion criteria and had at least 1 postoperative surveillance colonoscopy performed. The proportion of patients who had polyp and adenoma on surveillance colonoscopy was significantly higher among patients with L-sided than R-sided cancers (polyps: 30.9% vs. 19.6%, P=0.03; adenomas: 25.5% vs. 13.1%, P=0.01). The mean number of adenoma per patient on surveillance colonoscopy was also higher for patients with L-sided than R-sided tumors (0.52; 95% confidence interval [CI], 0.37-0.68 vs. 0.22; 95% CI, 0.08-0.35; P<0.01). Multivariate analysis showed that L-sided cancers, age, male gender and longer follow-up were independent predictors of adenoma detection on surveillance colonoscopy. Conclusions: Patients with Lsided cancer had a higher rate of metachronous polyps and adenoma than those with R-sided cancer on surveillance colonoscopy. PMID- 30301329 TI - Seven days triple therapy for eradication of Helicobacter pylori does not alter the disease activity of patients with inflammatory bowel disease. AB - Background/Aims: The influences of Helicobacter pylori eradication therapy on the disease course of inflammatory bowel disease (IBD) are still unclear. We therefore conducted a multicenter, retrospective cohort study to evaluate the safety of H. pylori eradication therapy for IBD patients. Methods: IBD patients with H. pylori eradication from 2005 to 2015 (eradication group) and control patients (non-eradication group; 2 paired IBD patients without H. pylori eradication matched with each eradicated patient) were included. IBD exacerbation (increased/additional IBD drug or IBD-associated hospitalization/surgery) and disease improvement based on the physicians' global assessment were investigated at baseline, and at 2 and 6 months after eradication or observation. Results: A total of 429 IBD (378 ulcerative colitis, 51 Crohn's disease) patients, comprising 144 patients in the eradication group and 285 patients in the non eradication group, were enrolled at 25 institutions. IBD exacerbation was comparable between groups (eradication group: 8.3% at 2 months [odds ratio, 1.76; 95% confidence interval, 0.78-3.92; P=0.170], 11.8% at 6 months [odds ratio, 1.60; 95% confidence interval, 0.81-3.11; P=0.172]). Based on the physicians' global assessment at 2 months, none of the patients in the eradication group improved, whereas 3.2% of the patients in the non-eradication group improved (P=0.019). Multivariate analysis revealed that active disease at baseline, but not H. pylori eradication, was an independent factor for IBD exacerbation during 2 months' observation period. The overall eradication rate was 84.0%-comparable to previous reports in non-IBD patients. Conclusions: H. pylori eradication therapy does not alter the short-term disease activity of IBD. PMID- 30301330 TI - Response to hepatitis B vaccination in patients with inflammatory bowel disease: a prospective observational study in Korea. AB - Background/Aims: Testing for hepatitis B virus (HBV) serologic markers and appropriate vaccination are required in the management of inflammatory bowel disease (IBD) patients. We evaluated immunogenicity for HBV in IBD patients and the response to the HBV vaccination. Methods: From May 2014 to August 2016, patients diagnosed with IBD were prospectively included and evaluated for anti HBs antibody, anti-HBc antibody, and HBs antigen. Among the 73 patients who were confirmed with nonimmunity to HBV, 44 patients who had completed the 3-dose HBV vaccination series received a single booster vaccination, while 29 patients who had not completed the vaccinations series or were unsure of receiving the vaccination received a full vaccination series. Results: An optimal response was obtained in 70.5% of the patients in the booster group, and 89.7% of the patients in the full vaccination group. Age younger than 26 years (odds ratio [OR], 6.01; 95% confidence interval [CI], 1.15-31.32; P=0.033) and a complete previous vaccination series (OR, 0.15; 95% CI, 0.03-0.80; P=0.026) were associated with optimal vaccine response. Previous complete vaccination series (OR, 0.11; 95% CI, 0.02-0.73; P=0.022) was the only predictive factor for lower compliance. Conclusions: The response to the HBV vaccination was lower in patients older than 26 years and for those patients with a complete vaccination history. Since patients with a complete vaccination history also had poor compliance, serum HBV titers should be checked more thoroughly, and a full vaccination series should be administered in cases when there is a negative response to the booster vaccination. PMID- 30301331 TI - High risk of tuberculosis during infliximab therapy despite tuberculosis screening in inflammatory bowel disease patients in India. AB - Background/Aims: The data on the risk of tuberculosis (TB) reactivation with infliximab (IFX) in patients with inflammatory bowel disease (IBD) from TB endemic countries, like India, is limited. The risk of TB reactivation on IFX and its predictors in patients with IBD was assessed. Methods: This retrospective review included consecutive patients with IBD who received IFX, and were on follow-up from January 2005 to November 2017. The data was recorded on age/disease duration, indications for IFX, screening for latent tuberculosis (LTB) before IFX, response to IFX, incidence and duration when TB developed after IFX, and type of TB (pulmonary [PTB]/extra-pulmonary [EPTB]/disseminated). Results: Of 69 patients (22 ulcerative colitis/47 Crohn's disease; mean age, 35.6+/-14.5 years; 50.7% males; median follow-up duration after IFX, 19 months [interquartile range, 5.5-48.7 months]), primary non-response at 8 weeks and secondary loss of response at 26 and 52 weeks were seen in 14.5%, 6% and 15% patients respectively. Prior to IFX, all patients were screened for LTB, 8 (11.6%) developed active TB (disseminated, 62.5%; EPTB, 25%; PTB, 12.5%) after a median of 19 weeks (interquartile range, 14.0-84.5 weeks) of IFX. Of these 8 patients' none had LTB, even when 7 of 8 were additionally screened with contrast enhanced chest tomography. Though not statistically significant, more patients with Crohn's disease than ulcerative colitis (14.9% vs. 4.5%, P=0.21), and those with past history of TB (25% vs. 9.8%, P=0.21), developed TB. Age, gender, disease duration, or extraintestinal manifestations could not predict TB reactivation. Conclusions: There is an extremely high rate of TB with IFX in Indian patients with IBD. Current screening techniques are ineffective and it is difficult to predict TB after IFX. PMID- 30301332 TI - Patient self-reported symptoms using visual analog scales are useful to estimate endoscopic activity in ulcerative colitis. AB - Background/Aims: In clinical practice, colonoscopy has been regarded as the gold standard for the evaluation of disease severity as well as mucosal healing in ulcerative colitis (UC). Some activity indices incorporating patient symptoms as parameters have been shown to reflect the endoscopic activity of UC. The aim of this study was to examine whether self-reported symptoms with visual analog scales (VAS) can predict endoscopic activity. Methods: A cross-sectional study of 150 UC patients who underwent colonoscopy with submission of VAS scores of 4 symptoms: general condition, bloody stools, stool form, and abdominal pain (0: no symptoms, 10: the most severe symptoms). Each VAS score was compared with colonoscopic activity assessed with the Mayo endoscopic subscore (MES). Results: All VAS scores were significantly correlated with the endoscopic severity (Spearman correlation coefficients of general condition, bloody stools, stool form, and abdominal pain: 0.63, 0.64, 0.58, and 0.43, respectively). Mucosal healing defined as MES 0 alone was predicted by VAS score <1.5 on general condition or 0 on bloody stools with sensitivity of 0.84 and 0.76 and specificity of 0.66 and 0.76, respectively. Additionally, VAS score <2.5 on stool form predicted active lesions in distal colorectum alone with sensitivity of 0.67 and specificity of 0.66, suggesting that this item could predict the indication of topical therapy. Conclusions: Self-reported VAS scores on symptoms were correlated with endoscopic activity of UC. To clarify the relationship between VAS and mucosal healing, further validation studies are needed. PMID- 30301333 TI - Medication non-adherence in inflammatory bowel diseases is associated with disability. AB - Background/Aims: Medication non-adherence is common in inflammatory bowel diseases (IBD). The short-term consequences of non-adherence include increased disease relapse but the long-term impact upon patients in terms of daily functional impairment are less well characterized. Identifying negative outcomes, such as disability, may encourage adherence. Methods: Consecutive ambulatory IBD subjects completed the Medication Adherence Rating Scale (MARS; non-adherence defined as <=16), Inflammatory Bowel Diseases Disability Index (IBD-DI; disability: <3.5) and Beliefs about Medicines Questionnaire (high necessity/concerns: >=16). The primary outcome was the association between medication non-adherence and disability. Secondary outcomes were the predictors of these outcomes. Results: A total of 173 subjects on IBD maintenance medications were recruited (98 Crohn's disease, 75 ulcerative colitis: median IBD DI, -5.0; interquartile range [IQR], -14.0 to 4.0 and median MARS, 19.0; IQR, 18 to 20) of whom 24% were non-adherent. Disability correlated significantly with medication non-adherence (r=0.38, P<0.0001). Median IBD-DI for non-adherers was significantly lower than adherers (-16.0 vs. -2.0, P<0.0001). Predictors of disability included female sex (P=0.002), previous hospitalization (P=0.023), management in a referral hospital clinic (P=0.008) and medication concerns (P<0.0001). Non-adherence was independently associated with difficulty managing bowel movements (odds ratio [OR], 3.71; 95% confidence interval [CI], 1.50-9.16, P=0.005), rectal bleeding (OR, 2.69; 95% CI, 1.14-6.36; P=0.024) and arthralgia/arthritis (OR, 2.56; 95% CI, 1.11-5.92; P=0.028). Conclusions: Medication non-adherence was associated with significantly increased disability in IBD. Female gender, higher disease severity and medication concerns were additional predictors of disability. PMID- 30301334 TI - 5-Aminosalicylic acid aggravates colitis mimicking exacerbation of ulcerative colitis. AB - Ulcerative colitis (UC) is one of the major clinical phenotypes of inflammatory bowel diseases. Although 5-aminosalicylic acid (5-ASA) is widely used for UC and its efficacy and safety have been demonstrated, a few patients paradoxically develop a severe exacerbation of colitis by 5-ASA administration. It is crucial to know clinical features including endoscopic findings in this condition for making a correct diagnosis and a prompt decision to withdraw the medication. Here, we report case series with UC exacerbated by 5-ASA. Medical records of 8 UC patients experiencing an exacerbation of colitis after induction of 5-ASA that was improved by the withdrawal of 5-ASA but also re-aggravated by dose increase or re-administration of 5-ASA were reviewed. The patients were newly diagnosed with UC, started 5-ASA and developed an exacerbation in approximately 2 to 3 weeks. They did not appear to have systemic allergic reactions. Seven of the 8 patients had a high fever. Three of 5 patients who undertook total colonoscopy showed right-side-dominant colitis. These findings suggest clinical characteristics in this condition. Further assessment of clinical and endoscopic features in more cases is necessary for establishing diagnostic criteria and understanding underlying mechanisms in those cases where 5-ASA aggravates the colitis. PMID- 30301335 TI - Usefulness of fecal immunochemical test and fecal calprotectin for detection of active ulcerative colitis. AB - Background/Aims: Ulcerative colitis undergoes periods of exacerbation and remission. Fecal calprotectin levels increase with gut inflammation and correlate with endoscopic disease activity in ulcerative colitis. Intestinal blood loss and fecal immunochemical test levels also correlate with endoscopic disease activity. This study statistically evaluated the usefulness of fecal calprotectin, fecal immunochemical test, and C-reactive protein (CRP) as markers of disease activity. Methods: A total 106 ulcerative colitis patients who underwent endoscopy and fecal calprotectin, fecal immunochemical test, and CRP testing, from March 2015 to August 2016, were retrospectively reviewed. Disease activity was assessed using a partial Mayo score and Mayo endoscopic score. The ability of fecal and serologic tests to reflect endoscopic disease severity was statistically evaluated. Results: Among 106 patients, 68 underwent endoscopy and stool study within 2 weeks. In patients with mild to severe activity, fecal immunochemical test and fecal calprotectin were superior to CRP at Mayo endoscopic score detection rate. The area under the curves of fecal immunochemical test and fecal calprotectin for the detection of Mayo endoscopic score >=1 were 0.956 and 0.942, respectively, and were superior to that of CRP (0.756). At Mayo endoscopic score, the effects of combination of fecal immunochemical test and CRP or fecal calprotectin and CRP were found to be higher than those of the independent fecal immunochemical test or fecal calprotectin. Conclusions: Fecal immunochemical test and fecal calprotectin can effectively detect active ulcerative colitis better than remission. As these markers reflect the status of mucosal inflammation, they may reduce the requirement for invasive endoscopic examination.

PMID- 30301338 TI - Vitamin D deficiency is associated with disease activity in patients with Crohn's disease. AB - Background/Aims: Previous data suggest that vitamin D has a significant role in inflammatory bowel disease (IBD). We investigated the incidence of vitamin D deficiency in Korean patients with IBD and the correlation between serum vitamin D level and disease activity. Methods: We retrospectively analyzed the medical records of patients with IBD whose serum vitamin D levels were checked. Deficiency of 25-hydroxyvitamin D was defined as <20 ng/mL. Disease activity was evaluated using the partial Mayo score for ulcerative colitis (>=2 defined as active disease) and Harvey-Bradshaw index for Crohn's disease (>=4 defined as active disease). Results: We enrolled 87 patients with IBD (UC, 45; CD, 42). Among them, 65.5% (57/87) were men, with a mean age of 44.9+/-15.1 years (range, 18-75 years). The mean duration of disease was 4.7+/-4.8 years (range, 0.1-17.1 years). Vitamin D deficiency was found in 73.6% (64/87) of patients with IBD. Patients with IBD (mean vitamin D level, 16.3+/-9.0 ng/mL) showed lower vitamin D level than the healthy control group (mean vitamin D level, 20.4+/-7.0 ng/mL), with no statistically significant difference (P=0.136). Disease activity was inversely correlated with vitamin D deficiency in patients with CD (P=0.007). However, no correlation was observed in patients with UC (P=0.134). Conclusions: Approximately 75% of Korean patients with IBD showed vitamin D deficiency state. Vitamin D deficiency is associated with disease activity, particularly in patients with CD. PMID- 30301339 TI - Experience of patients with inflammatory bowel disease in using a home fecal calprotectin test as an objective reported outcome for self-monitoring. AB - Background/Aims: Fecal calprotectin (fC) level is a predictive marker of mucosal healing for patients with inflammatory bowel disease (IBD). Home fC tests are now available. We evaluated the performance of the smartphone-based IBDoc home testing system in patients with IBD and obtained their feedback as an objective patient-reported outcome. Methods: This prospective study enrolled consecutive patients with IBD in clinical remission. fC in the same stool sample was assessed by using both the laboratory test (Quantum Blue calprotectin test) and home test (IBDoc). The correlation between the 2 tests was analyzed using the Pearson method. In addition, the patients were asked to fill a questionnaire based on their experience. Results: Fifty-one patients with IBD (68 tests and 49 questionnaires) were included. The correlation between Quantum Blue test and IBDoc was good (r=0.776, P<0.0001). After the test, 56% patients found IBDoc easy to perform, and 96% were satisfied with it. Thirty-nine patients (80%) had a strong (>70%) probability to use it for future monitoring if the price was acceptable. By using 250 MUg/g as the cutoff, the agreement between home test and laboratory results was 80%, and by using 600 MUg/g as the cutoff, the agreement increased to 92%. Conclusions: The correlation between the laboratory and home tests was good. Most patients found the home test to be feasible and easy to use and preferred it over laboratory test and endoscopy for monitoring. Therefore, the home test could be used as an objective patient-reported outcome. PMID- 30301340 TI - The current capacity and quality of colonoscopy in Korea. AB - Background/Aims: Little is known for the capacity and quality of colonoscopy, and adherence to colonoscopy surveillance guidelines in Korea. This study aimed to investigate the present and potential colonoscopic capacity, colonoscopic quality, and adherence to colonoscopy surveillance guidelines in Korea. Methods: We surveyed representative endoscopists of 72 endoscopy units from June to August 2015, using a 36-item questionnaire regarding colonoscopic capacity, quality, and adherence to colonoscopy surveillance guidelines of each hospitals. Results: Among the 62 respondents who answered the questionnaire, 51 respondents were analyzed after exclusion of 11 incomplete answers. Only 1 of 3 of endoscopy units can afford to perform additional colonoscopies in addition to current practice, and the potential maximum number of colonoscopies per week was only 42. The quality of colonoscopy was variable as reporting of quality indicators of colonoscopy were considerably variable (29.4%-94.1%) between endoscopy units. Furthermore, there are substantial gaps in the adherence to colonoscopy surveillance guidelines, as concordance rate for guideline recommendation was less than 50% in most scenarios. Conclusions: The potential capacity and quality of colonoscopy in Korea was suboptimal. Considering suboptimal reporting of colonoscopic quality indicators and low adherence rate for colonoscopy surveillance guidelines, quality improvement of colonoscopy should be underlined in Korea. PMID- 30301337 TI - Usefulness of fecal calprotectin by monoclonal antibody testing in adult Japanese with inflammatory bowel diseases: a prospective multicenter study. AB - Background/Aims: Noninvasive objective monitoring is advantageous for optimizing treatment strategies in patients inflammatory bowel disease (IBD). Fecal calprotectin (FCP) is superior to traditional biomarkers in terms of assessing the activity in patients with IBD. However, there are the differences among several FCP assays in the dynamics of FCP. In this prospective multicenter trial, we investigated the usefulness of fecal FCP measurements in adult Japanese patients with IBD by reliable enzyme immunoassay using a monoclonal antibody. Methods: We assessed the relationship between FCP levels and disease or endoscopic activity in patients with ulcerative colitis (UC, n=64) or Crohn's disease (CD, n=46) compared with healthy controls (HCs, n=64). Results: FCP levels in UC patients strongly correlated with the Disease Activity Index (rs=0.676, P<0.0001) and Mayo endoscopic subscore (MES; rs=0.677, P<0.0001). FCP levels were significantly higher even in patients with inactive UC or CD compared with HCs (P=0.0068, P<0.0001). The optimal cutoff value between MES 1 and 2 exhibited higher sensitivity (94.1%). FCP levels were significantly higher in active UC patients than in inactive patients (P<0.001), except those with proctitis. The Crohn's Disease Activity Index tended to correlate with the FCP level (rs=0.283, P=0.0565). Conclusions: Our testing method using a monoclonal antibody for FCP was well-validated and differentiated IBD patients from HCs. FCP may be a useful biomarker for objective assessment of disease activity in adult Japanese IBD patients, especially those with UC. PMID- 30301341 TI - IBD2020 global forum: results of an international patient survey on quality of care. AB - Background/Aims: IBD2020 is a global forum for standards of care in inflammatory bowel disease (IBD). The aim of the IBD2020 survey was to identify and describe variations in quality care of IBD. Methods: Patients with IBD from Finland, Italy, France, Canada, Germany, UK, Spain and Sweden were surveyed during 2013 to 2014, covering: disease characteristics; impact on life and work; organization and perceived quality of care. Results: Seven thousand five hundred and seven patients participated (median age, 39 years [range, 10-103 years]; 2,354 male [31.4%]), including 4,097 (54.6%) with Crohn's disease (CD) and 3,410 (45.4%) with ulcerative colitis (UC). Median time from symptom onset to diagnosis was 1 year for both CD (range, 0-47 years) and UC (range, 0-46 years), with no clear evidence of improvement in diagnostic delay over the preceding 24 years. Half of the patients (3,429; 50.0%) rated their care as "excellent" or "very good," with similar results for CD and UC across countries. Five factors were significantly (P<0.01) associated with perceived good quality of care: quality of specialist communication; review consultation being long enough; failure to share information; no access to a dietician; speed of advice. Conclusions: The IBD2020 survey has highlighted areas related to quality of care of IBD from the patients' perspective, with scope for improvement. PMID- 30301342 TI - Clinicopathological feature and treatment outcome of patients with colorectal laterally spreading tumors treated by endoscopic submucosal dissection. AB - Background/Aims: Endoscopic submucosal dissection (ESD) is an advanced technique that can be used to treat precancerous and early colorectal neoplasms by facilitating en bloc resection regardless of tumor size. In our study, we investigated the clinicopathological feature and the treatment outcome of patients with colorectal laterally spreading tumors (LSTs) that were treated by ESD. Methods: The study enrolled all of 210 patients with colorectal LSTs who underwent ESD. Clinical outcomes were analyzed by retrospectively reviewing medical records. Results: A cancerous pit pattern (Vi/Vn) was more common in pseudo-depressed (PD) subtype than in flat elevated (FE) subtype. The incidence of adenocarcinoma in the PD subtype and nodular mixed (NM) subtypes was significantly higher than in the homogenous (HG) subtype and FE subtype. The en bloc and R0 resection rates were 89.0% and 85.7%, respectively. The bleeding and perforation rates were 5.2% and 1.9%, respectively. The mean procedure time was much longer in the PD subtype than in the FE subtype. The en bloc resection rate was significantly higher in the NM subtype than in the HG subtype. However, there were no statistically significant differences in mean procedure time, en bloc resection rate, R0 resection rate, bleeding rate, or perforation rate between LST granular and LST-nongranular types. Conclusions: These results indicate that ESD is acceptable for treating colorectal LSTs concerning en bloc resection, curative resection, and risk of complications. Careful consideration is required for complete resection of the PD subtype and NM subtype because of their higher malignant potential. PMID- 30301343 TI - Development and diversity of lactic acid producing bacteria and bifidobacteria in healthy full term Indian infants from Himachal Pradesh. AB - Background/Aims: The initial microbial colonization is a crucial step for the healthy development of an infant. Previous studies from India reported the dominance of target microbial species among Indian infants without any analysis on the diversity of target groups. This is the first study from India with an objective to investigate the establishment and diversity of lactic acid producing bacteria (LAB) and bifidobacteria in vaginally delivered, full term, breastfed infants for the first 4 months after birth. Methods: Present study used polymerase chain reaction-denaturating gradient gel electrophoresis (PCR-DGGE) based sequence analysis of LAB and bifidobacteria in healthy infants. The results were used to compare the development and early colonization by LAB and bifidobacteria using diversity indices during the initial months of development of gut microbiota in infants. Results: During the first 4 months, the Shannon diversity index (H) of LAB increased from 1.16 to 1.318 and for bifidobacteria the H increased from 0.975 to 1.293 (P<0.05). Higher Sorenson's pair wise similarity coefficient was observed for LAB and bifidobacteria during 2nd and the 3rd month. The species of the genera Enterococcus, Streptococcus, and Lactobacillus were dominant among the LAB group whereas Bifidobacterium breve was dominant species among Bifidobacterium group. Conclusions: Our results indicate that in breast fed infants, the microbial diversity of LAB and bifidobacteria increased during the period of study. PMID- 30301344 TI - Clinical features and outcomes in spontaneous intramural small bowel hematoma: Cohort study and literature review. AB - Background/Aims: Spontaneous intramural small bowel hematoma (SISBH) is an extremely rare complication of anticoagulant or antiplatelet therapy. We assessed the clinical characteristics and outcomes of patients with SISBH according to the anatomical location of the hematoma. Methods: From January 2003 to February 2016, medical records for all patients hospitalized for SISBH at 2 tertiary referral hospitals were retrospectively reviewed. The primary outcome was requirement for surgery. Results: A total of 37 patients were enrolled. The mean age was 74.1 years. Among them, 33 patients (89.2%) were taking anticoagulant and/or antiplatelet agents. Duodenal intramural hematoma was detected in 4 patients (10.8%), jejunal in 16 (43.2%), and ileal in 17 (45.9%). Compared to jejunal and ileal involvement, duodenal intramural hematoma was significantly associated with high Charlson comorbidity index and low levels of white blood cells, hemoglobin, and platelets in the blood. SISBH in the duodenum was related to thrombocytopenia in 3 patients following systemic chemotherapy for malignancy. All patients with SISBH showed clinical improvement with conservative therapy. Mean length of hospital stay was 9.35 days. Independent predictors of a hospital stay of more than 7 days were body weight less than 60 kg (odds ratio [OR], 12.213; 95% confidence interval [CI], 1.755-84.998; P=0.011) and a history of cerebrovascular accidents (OR, 6.667; 95% CI, 1.121-39.650; P=0.037). Conclusions: Compared to jejunal and ileal involvement, thrombocytopenia may result in spontaneous duodenal intramural hematoma among patients who are treated with systemic chemotherapy for malignancies. Patients with SISBH have excellent clinical outcomes with conservative therapy regardless of the anatomical location of the hematoma. PMID- 30301345 TI - Methoxyphosphinidene and Isomeric Methylphosphinidene Oxide. AB - A rare oxyphosphinidene (Me-OP) has been generated in the triplet ground state through either photolysis (266 nm) or flash-vacuum pyrolysis (FVP, 700 degrees C) of methoxydiazidophosphine MeOP(N3)2. Upon ArF laser irradiation (193 nm), an unprecedented isomerization from Me-OP to the long-sought methylphosphinidene oxide (Me-PO) occurs in cryogenic Ne- and N2-matrices. Alternatively, the latter can be efficiently generated through photolysis (193 nm) or FVP (ca. 700 degrees C) of methylphosphoryl diazide MeP(O)(N3)2, in which the elusive nitrene intermediate MeP(O)(N3)N in the triplet ground state has been also observed by IR (with 15N-labeling) and EPR (| D/ hc| = 1.545 cm-1 and | E/ hc| = 0.003 95 cm-1) spectroscopy.

AB - Multifarious sugar lactols were efficiently transformed into the corresponding phenolic glycosides by treating with aryl bromides in acetonitrile with Ir[dF(CF3)ppy]2(dtbbpy)(PF6) as a photocatalyst under visible light irradiation. Both pyranoses and furanoses or even disaccharide could all suffer this glycosylation protocol under mild reaction conditions. A variety of phenyl glycosides can be produced in moderate to good yields (up to 93% yield), and a gram scale process of this protocol was also well-established.

AB - A water-based one-pot synthesis strategy for converting cellulose nanofibrils (CNF) into a hydrophobic and processable biopolymer grade is devised. CNF was chemically modified through admicellar polymerization, producing fibrils coated with fatty acrylate polymers. The proposed modification targets a change in the interfibrillar interactions and improved CNF compatibility with a degradable plastic composite matrix, poly(butylene adipate- co-terephthalate), PBAT in composites prepared by melt extrusion. CNF had a clear reinforcing effect on PBAT, increasing Young's modulus by at least 35% and 169% at 5 and 20% (w/w) CNF content, respectively. However, unmodified CNF showed aggregation, poor adhesion in the matrix, and severely impaired the ductility of PBAT. CNF modified by admicellar polymerization was homogeneously dispersed in the PBT matrix and showed significantly better preservation of the elongation properties compared to unmodified CNF, especially at 5% (w/w) addition level.

AB - The three-dimensional (3D) printed scaffolds were prepared by partial cross linking of TEMPO-oxidized cellulose nanofibril/alginate hydrogel using calcium ions for printing the hydrogel while maintaining its shape, fidelity, and preventing the collapse of the filaments. The prepared scaffolds were fully cross linked using calcium ions immediately after printing to provide the rigidity of the hydrogel and give it long-term stability. The composition of the prepared pastes was adjusted in view of the description of the hydrogel and 3D printing parameters. The rheological properties in terms of thixotropic behavior and viscosity recovery of hydrogels were investigated by performing steady shear rate experiments. The results show that the viscosity recovery for pure alginate hydrogel was only about 16% of the initial value, whereas it was 66% when adding cellulose nanofibrils to alginate. Consequently, the shape of the pure alginate scaffold was soft and easy to collapse contrarily to the composite scaffold. The biomimetic mineralization process of printed scaffolds using simulated body fluid, mimicking the inorganic composition of human blood plasma, was performed and the hydroxyapatite nucleation on the hydrogel was confirmed. The strength properties of the fabricated scaffolds in terms of compressive strength analysis were also investigated and discussed. The results show that the alginate/TEMPO oxidized cellulose nanofibril system may be a promising 3D printing scaffold for bone tissue engineering.

AB - We have developed a series of carbazole-derived compounds based on our hybrid D2/D3 agonist template to design multifunctional compounds for the symptomatic and disease-modifying treatment of Parkinson's disease (PD). The lead molecules ( )-11b (D-636), (-)-15a (D-653), and (-)-15c (D-656) exhibited high affinity for both D2 and D3 receptors and in GTPgammaS functional assay, the compounds showed potent agonist activity at both D2 and D3 receptors (EC50 (GTPgammaS); D2 = 48.7 nM, D3 = 0.96 nM for 11b, D2 = 0.87 nM, D3 = 0.23 nM for 15a and D2 = 2.29 nM, D3 = 0.22 nM for 15c). In an animal model of PD, the test compounds exhibited potent in vivo activity in reversing hypolocomotion in reserpinized rats with a long duration of action compared to the reference drug ropinirole. In a cellular antioxidant assay, compounds (-)-11b, (-)-15a, and (-)-15c exhibited potent activity in reducing oxidative stress induced by neurotoxin 6-hydroxydopamine (6 OHDA). Also, in a cell-based PD neuroprotection model, these lead compounds significantly increased cell survival from toxicity of 6-OHDA, thereby producing a neuroprotective effect. Additionally, compounds (-)-11b and (-)-15a inhibited aggregation and reduced toxicity of recombinant alpha synuclein protein in a cell based in vitro assay. These observations suggest that the lead carbazole-based dopamine agonists may be promising multifunctional molecules for a viable symptomatic and disease-modifying therapy of PD and should be further investigated. PMID- 30301350 TI - Compound Molecular Logic in Accessing the Active Site of Mycobacterium tuberculosis Protein Tyrosine Phosphatase B. AB - Protein tyrosine phosphatase B (PtpB) from Mycobacterium tuberculosis (Mtb) extends the bacteria's survival in hosts and hence is a potential target for Mtb specific drugs. To study how Mtb-specific sequence insertions in PtpB may regulate access to its active site through large-amplitude conformational changes, we performed free-energy calculations using an all-atom explicit solvent model. Corroborated by biochemical assays, the results show that PtpB's active site is controlled via an "either/or" compound conformational gating mechanism, an unexpected discovery that Mtb has evolved to bestow a single enzyme with such intricate logical operations. In addition to providing unprecedented insights for its active-site surroundings, the findings also suggest new ways of inactivating PtpB. PMID- 30301351 TI - Comparison of the Effects and Inhibitory Pathways of the Constituents from Gynostemma pentaphyllum against LPS-Induced Inflammatory Response. AB - Saponins, the primary phytochemicals contributing to the health properties of G. pentaphyllum were frequently studied. However, compounds responsible for its bioactivities were still poorly understood. The saponin-rich fraction (GPMS), 3- O-[2G-( E)-Coumaroyl-3G- O-beta-d-glucosyl-3R- O-beta-d-glucosylrutinoside] (KCGG), gypenoside XLVI and gypenoside L were obtained by purification of G. pentaphyllum. The compounds were examined and compared with GPMS for their inhibitory effects on LPS-induced nitric oxide (NO) production. GPMS and KCGG differed in their inhibitory capacities against pro-inflammatory cytokines secretion. GPMS exhibited strong inhibition on inducible nitric oxide synthase (iNOS) and interleukin-6 (IL-6) mRNA expression but weak inhibition on tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta mRNA expression. KCGG was better at inhibiting iNOS, IL-6, TNF-alpha, and cyclooxygenase-2 (COX-2) mRNA expression. GPMS showed similar inhibitory potency on mitogen-activated protein kinase phosphorylation and nuclear factor-kappaB (NF-kappaB) activation, as evidenced by their regulatory effects on LPS-induced P65 phosphorylation, NF kappaB nuclear translocation, IkappaBalpha phosphorylation and degradation, IkappaKalpha/beta phosphorylation, c-Jun N-terminal kinase phosphorylation, P38 phosphorylation, and COX-2 expression. KCGG was more powerful in inhibiting the NF-kappaB pathway, suggesting that KCGG might be used in the management of inflammatory-associated diseases in which NF-kappaB played pivotal roles. Furthermore, KCGG might be mainly responsible for the predominant effects of GPMS. PMID- 30301352 TI - Orientation Relaxation Dynamics in Cellulose Nanocrystal Dispersions in the Chiral Liquid Crystalline Phase. AB - A Landau-de Gennes formulation was implemented in dynamic finite element simulations to compare with postshear relaxation experiments that were conducted on cholesteric cellulose nanocrystal (CNC) dispersions. Our study focused on the microstructural reassembly of CNCs in lyotropic dispersions as parameters such as chiral strength and gap confinement were varied. Our simulation results show that homeotropic and/or more complicated three-dimensional helical configurations are possible, depending on the choice of these parameters. We also observed how dynamic banding patterns develop into the hierarchical microstructures that are characterized by an equilibrium pitch length in both the experiments and simulations. This work has immediate relevance for cellulose nanocrystal dispersion processing and provides new insight into fluid phase ordering for tailorable optical properties. PMID- 30301353 TI - Amphiphilic Cellulose Nanocrystals for Enhanced Pickering Emulsion Stabilization. AB - Sulfated cellulose nanocrystals (CNC) with high surface charge density are inadequate for stabilizing oil-water emulsions, which limits their applications as interfacial stabilizers. We performed end-group modification by introducing hydrophobic chains (polystyrene) to CNC. Results showed that the modified CNC are more effective in emulsifying toluene and hexadecane than pristine CNC. Various parameters were investigated, such as concentration of particles, electrolytes, and polarity of solvents on the characteristics of the emulsions. This study provides strategies for the modification of cellulose nanocrystals to yield amphiphilic nanoparticles that enhance the stability of emulsions. Such systems, bearing biocompatible and environmentally friendly characteristics, are attractive for use in a wide range of industries spanning food, biomedicine, pharmaceuticals, cosmetics, and petrochemicals. PMID- 30301354 TI - Copper-Catalyzed Unstrained C-C Single Bond Cleavage of Acyclic Oxime Acetates Using Air: An Internal Oxidant-Triggered Strategy toward Nitriles and Ketones. AB - A copper-catalyzed aerobic oxidative C-C single bond cleavage of acyclic unstrained oxime acetates is reported, providing various aryl nitriles and ketones in good yields. Mechanistic studies indicate a radical procedure is involved in this transformation, and the oxygen atom in the ketone products is originated from O2 in the air. Oxime acetates as an internal oxidant have been proved to be an initiator, which may promote the discovery of novel protocol for C-C bond cleavage and dioxygen activation.

AB - INTRODUCTION: Specific and targeted intervention is needed to reduce the relatively high maternal mortality and morbidity in Indonesia. The apparent rural urban disparities might require different intervention strategies. Therefore, this study aims to assess patterns and sociodemographic determinants of self reported maternal morbidity in rural and urban areas. METHODS: Data from the Indonesian Demographic and Health Survey 2012 were analyzed. In this cross sectional survey, maternal morbidity status and sociodemographic factors were obtained through questionnaire-based interviews. Women who completed the maternal morbidity questionnaire were included in the analyses (n=12 679). Descriptive statistics were used to assess differences in proportion; mixed-effects regression was used to evaluate the association between sociodemographic factors and maternal morbidity. RESULTS: Approximately 53.3% of women reported experiencing pregnancy and/or labor complications, with a lower proportion in rural areas (51.3%) than in urban areas (55.1%). The patterns of pregnancy morbidities were similar for rural and urban women. The highest proportion of pregnancy morbidity was classified as 'other', followed by 'bleeding'. There were slight differences in the type of labor morbidities. Compared to urban women, women in rural areas had a higher prevalence of bleeding and infection, but a significantly lower prevalence of pregnancy rupture of membrane. Nulliparity was a dominant factor for self-reported maternal morbidity. Younger urban, but not rural, women represented a higher proportion of maternal morbidity. In urban areas, women with social disadvantage represented a higher proportion of morbidity. However, in rural areas, a higher prevalence of maternal morbidity was seen in women of higher socioeconomic status. These rural-urban disparities might be partially caused by differences in knowledge of maternal morbidities and sociodemographic status between rural and urban women. CONCLUSIONS: This study found similar patterns of pregnancy morbidity, but slight differences in labor morbidity patterns. Specific interventions for major maternal complications within rural or urban areas are important. There were also differences in the proportion of self-reported maternal complications by sociodemographic factors, which might be caused by differences in reporting. Intervention to improve knowledge and awareness of maternal complication is needed, specifically for socially disadvantaged women and women living in rural areas. PMID- 30301358 TI - Effects of Hand Exercise on Eating Action in Patients With Alzheimer's Disease. AB - We aim to investigate whether a popular hand exercise could be used to improve the action of eating in patients with Alzheimer's disease (AD). A 6-month intervention was conducted in 60 patients with AD who live in a nursing home. They were divided into hand exercise and control groups. Patients of the control group maintained their daily routine. The improvement of Edinburgh Feeding Evaluation in Dementia scale in hand exercise group was significantly greater than in the control group ( P = .003). Significant differences in time of autonomous eating and time of simulated eating between patients in the hand exercise and control groups ( P < .05) were noted. The improvements in accuracy of eating action and coordination of eating action from baseline were significant in hand exercise group compared to the control group ( P = .020 and .014, respectively). Hand exercise is a safe and effective intervention to improve the feeding and eating of people with AD. PMID- 30301360 TI - A decade of incurred sample reanalysis: failures, investigations and impact. AB - Incurred sample reanalysis (ISR) is used to ensure the validity and reliability of bioanalytical data. Additionally, ISR results also help identify issues that could influence or bias the data. Overall, based on a decade of experimental data generated at Eli Lilly and Company, ISR failures are few with less than 5% of ISR samples failing to meet acceptance criteria. In a majority of situations, the cause for ISR failures has been 'human-error.' However, there are examples where ISR has helped identify issues related to the stability of the analyte or the ruggedness of the method. As a strategy, it is beneficial to conduct ISR following the completion of a few sample runs, so any potential issues impacting the validity and reliability of the data can be identified and rectified early. PMID- 30301359 TI - Prevalence and predictors of electrocardiogram abnormalities among athletes. AB - Background Existing evidence, predominantly from Western countries, has demonstrated that athletes' hearts undergo structural, physiological, and electrical changes, leading to abnormal electrocardiogram readings that are said to be training-related. Athletes with non-training-related electrocardiographic abnormalities risk developing sudden cardiac death. The lack of studies on this issue in the Asian population warrants further exploration. Therefore, the aim of this study was to estimate the prevalence and predictive factors contributing to electrocardiogram abnormalities among athletes in Brunei. Methods A descriptive cross-sectional study was conducted on 100 athletes (median age 25.2 years) in 10 sporting disciplines, whose electrocardiogram readings and essential information was obtained. Results The prevalence of an abnormal electrocardiogram was 52% (95% confidence interval: 42.0%-62.0%), comprising training-related changes in 49% (95% confidence interval: 39.0%-59.0%) and non-training-related changes in 3% (95% confidence interval: 0.4%-6.4%). Athletes with a higher body mass index were 3.3-times (95% confidence interval: 1.47-9.58) more likely to have abnormal electrocardiogram readings. Athletes <25-years old (odds ratio = 0.25, 95% confidence interval: 0.07-0.81) and those who trained with low dynamic intensity (odds ratio = 0.33, 95% confidence interval: 0.12-0.93) were significantly less likely to have electrocardiogram abnormalities. Conclusions This is the first study reporting abnormal electrocardiograms among athletes in Brunei, which provides important information to relevant agencies involved in the preparation of Asian athletes for domestic or international competitions, particularly those with a higher body mass index and low dynamic training intensity.

AB - Recovery for many people with serious mental illness is more than symptom remission or attainment of certain concrete milestones. It can also involve recapturing a previously lost coherent and cohesive sense of self. The authors review several case studies of integrative metacognitive psychotherapy offered to adults with broadly differing clinical presentations. In all the cases, patients demonstrated significant subjective gains and objective improvements-for example, in negative symptoms, in substance use, and in overcoming a history of childhood sexual abuse. By applying this method to various problems-issues consistent with the realities faced in actual clinics-the authors explore how integrative metacognitive psychotherapy is able to address more subjective aspects of recovery by stimulating gains in the experience of agency that lead to the development of more cohesive self-experience, regardless of objective markers of recovery. PMID- 30301363 TI - Home Hospice Caregivers' Perceived Information Needs. AB - BACKGROUND: Although home hospice organizations provide essential care for and support to terminally ill patients, many day-to-day caregiving responsibilities fall to informal (ie, unpaid) caregivers. Studies have shown that caregivers value receiving clear information about end-of-life (EoL) care. Meeting the information needs of this group is critical in improving their experience in hospice. OBJECTIVES: To identify the information needs of informal home hospice caregivers. DESIGN: One hundred five semi-structured phone interviews with informal caregivers were conducted. Study data were analyzed using a standard qualitative method (ie, content analysis). PARTICIPANTS: Informal home hospice caregivers whose loved ones have been discharged (death or live discharge) from an urban, nonprofit hospice organization. Measured: Participants' information needs were ascertained by assessing whether information regarding hospice was or was not fully explained or whether there was information they wished they knew prior to the hospice transition. RESULTS: Among study participants, 48.6% had unmet information needs related to (1) general information about hospice (n = 17, 16.2%), (2) what to expect at the EoL (n = 19, 18.1%), and (3) support provided by hospice (n = 30, 28.6%). Specifically, caregivers expressed the need for more information on what hospice is, caring for a dying patient, and the day-to-day care hospice provides. CONCLUSION: Our study indicates that approximately half of the informal caregivers had unmet information needs. Further research is needed to identify efficacious strategies to best meet the information needs of this group. Specific topics that need emphasis include what hospice care is, what to expect at the EoL, and what level of support hospice offers. PMID- 30301364 TI - ISR: what have we learned after a decade of experience? AB - Within our company, incurred sample reproducibility (ISR) was implemented a decade ago. Only 11 studies (<2%) with failed ISR were identified over that period. These cases are described along with the strategy followed to resolve the issue. For three studies the failing ISR was caused by a method failure and all instances could be traced back to an instability problem. The majority of the failed ISR experiments were due to human error. For most of the studies the issue could be resolved and results reported. In two studies, no valid results could be generated. Based on this analysis we advise to limit the number of studies that require ISR assessment. PMID- 30301365 TI - How Low-Income Smokers in New York Access Cheaper Cigarettes. AB - PURPOSE: To understand the tobacco acquisition practices of low-income smokers in New York State in light of high cigarette prices due to high cigarette taxes. DESIGN: Eight focus groups with low-income smokers were conducted in spring 2015 and 2016 (n = 74). SETTING: New York City (NYC) and Buffalo, New York. PARTICIPANTS: Low-income adults aged 18 to 65 who smoke cigarettes regularly. METHOD: Qualitative analysis of focus group transcripts that explored differences and similarities by region. We used the interview guide-which covered the process of acquiring cigarettes and the impact of cigarette prices-as a framework for analysis to generate themes and subthemes (deductive coding). We also generated themes and subthemes that emerged during focus group discussions (inductive coding). RESULTS: Some smokers in Western New York have switched to untaxed cigarettes from Native American reservations, whereas low-income smokers in NYC described convenient sources of bootlegged cigarettes (packs or loosies) in their local neighborhood stores, through acquaintances, or on the street. Familiarity with the retailer was key to accessing bootlegged cigarettes from retailers. CONCLUSIONS: Smokers in this study could access cheaper cigarettes, which discouraged quit attempts and allowed them to continue smoking. The availability of lower priced cigarettes may attenuate public health efforts aimed at reducing smoking prevalence through price and tax increases. PMID- 30301367 TI - Effects of exercise on the physical fitness level of adults with intellectual disability: a systematic review. AB - PURPOSE: To systematically review the existing scientific evidence regarding the effects of physical exercise on the fitness level of people with intellectual disabilities. METHODS: Following the checklist of the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols, the PubMed, CINAHL, SPORTDiscus, and Scopus databases were searched using specific keywords up to January 2018. The methodological quality of the studies found was rated by the means of specific scales according to their specific design. RESULTS: A total of 44 studies were selected. The majority of the included studies were randomized controlled trials (n = 17), followed by non-controlled studies (n = 11), non randomized controlled trials (n = 10), and comparative studies (n = 6). Aerobic, strengthening, and combined exercise programs were the most frequently proposed interventions. Exercise showed to have significant effects on the cardiorespiratory and muscular fitness. Not all the selected studies reported improvements in parameters related to body composition. CONCLUSIONS: There is sufficient scientific evidence for the beneficial effects of exercise on the cardiovascular and muscular fitness of adults with mild/moderate ID. There is a need for more studies focused on the impact of physical exercise on the body composition of this population, and those that aim at identifying the impact of alternative interventions. IMPLICATIONS FOR REHABILITATION There is a need for basic guidelines that can help rehabilitation professionals to prescribe exercise for maintaining and improving physical fitness in the adults with intellectual disabilities. In adults with intellectual disabilities, aerobic exercise has beneficial effects on cardiovascular and muscular fitness, flexibility, and range of motion. No firm conclusion can be made regarding the effects of aerobic, muscular, and combined training programs on the body composition of adults with intellectual disabilities. Rehabilitation professionals should be aware that scientific evidence regarding the prescription of alternative exercise protocols in adults with intellectual disabilities (i.e. dancing, water-based exercise, animal therapy, etc) is scarce. PMID- 30301366 TI - Perirenal Fat: A Unique Fat Pad and Potential Target for Cardiovascular Disease. AB - Although visceral obesity is recognized as a risk factor for cardiovascular diseases (CVDs), the efficacy of omental fat removal in CVD treatment is still controversial. There is a need to identify other visceral fat depots for CVD management. This review aims to provide a summary on perirenal fat as an important risk factor for CVD. Studies on epidemiology, anatomy, and function of perirenal fat were reviewed. Observational studies in humans suggest that excessive perirenal fat increases the risk of hypertension and coronary heart disease. Anatomy studies prove that perirenal fat is unique compared to other connective tissues in that it is well vascularized, innervated, and drains into the lymphatic system. Other special morphological features include a complete fascia border, sympathetic-independent development of architecture, and proximity to the kidneys. Based on these anatomical features, perirenal fat regulates the cardiovascular system presumably via neural reflex, adipokine secretion, and fat kidney interaction. These new insights suggest that perirenal fat may constitute a promising target for CVD management. PMID- 30301368 TI - Advances in stem cell therapy for erectile dysfunction. AB - INTRODUCTION: Stem cell (SC) application is a promising area of research in regenerative medicine, with the potential to treat, prevent, and cure disease. In recent years, the number of studies focusing on SCs for the treatment of erectile dysfunction (ED) and other sexual dysfunctions has increased significantly. Areas covered: This review includes critical ED targets and preclinical studies, including the use of SCs and animal models in diabetes, aging, cavernous nerve injury, and Peyronie's disease. A literature search was performed on PubMed for English articles. Expert opinion: Combination treatment offers better results than monotherapy to improve pathological changes in diabetic ED. Regenerative medicine is a promising approach for the maintenance of sexual health and erectile function later in life. Cavernous nerve regeneration and vascular recovery employing SC treatment may be focused on radical prostatectomy-induced ED. Notwithstanding, there are a number of hurdles to overcome before SC-based therapies for ED are considered in clinical settings. Paracrine action, not cellular differentiation, appears to be the principal mechanism of action underlying SC treatment of ED. Intracavernosal injection of a single SC type should be the choice protocol for future clinical trials. PMID- 30301369 TI - GZD2202, a novel TrkB inhibitor, suppresses BDNF-mediated proliferation and metastasis in neuroblastoma models. AB - Collective data suggest tropomyosin-related kinase B (TrkB), which is correlated with the growth, migration and poor prognosis of neuroblastoma (NB), is a potential target for NB target therapy. Several Phase I/II pan-Trk inhibitors display impressive clinical outcomes but still no drug has been approved for general use. In this paper, we report a novel structural TrkB inhibitor GZD2202, a structural derivative of our previously identified DDR1 antagonists. GZD2202 demonstrates a moderate selectivity between Trk B/C and TrkA. GZD2202 suppresses the brain-derived neurotrophic factor (BDNF) -mediated TrkB signalling pathway, proliferation, migration and invasion in SH-SY5Y-TrkB neuroblastoma cells, and causes about 36.1% growth inhibition in a SH-SY5Y-TrkB neuroblastoma xenograft model. PMID- 30301370 TI - Objective ocular surface tolerance in patients with glaucoma treated with topical preserved or unpreserved prostaglandin analogues. AB - PURPOSE: Preservatives in glaucoma medications have been associated with ocular toxicity. We compared ocular signs and symptoms in patients with open-angle glaucoma or ocular hypertension treated in monotherapy with preserved or preservative-free prostaglandin analogues. METHODS: Observational cross-sectional clinical study in real life. 82 patients treated for at least 6 months with prostaglandin analogue were assessed for intraocular pressure, ocular symptoms and ocular signs including conjunctival hyperaemia, tear break-up time and tear meniscus height measured using objective and non-invasive methods (OCULUS Keratograph 5M). Patients presenting with symptoms of ocular toxicity with preserved prostaglandin analogues were switched to preservative-free latanoprost, and a second assessment was processed 6 months after. RESULTS: At inclusion, 30 (36.6%) patients were treated with preservative-free latanoprost, 25 (30.5%) with preserved latanoprost, 16 (19.5%) with preserved travoprost and 11 (13.4%) with preserved bimatoprost. Patients treated with preservative-free latanoprost reported significantly less ocular symptoms upon instillation (mainly burning) and between instillations than patients treated with preserved prostaglandin analogues. The mean conjunctival hyperaemia (limbal + bulbar) was significantly lower with preservative-free latanoprost (2.08 +/- 0.55) compared to preserved latanoprost (2.50 +/- 0.7, p = 0.0085), preserved travoprost (2.67 +/- 0.82, p = 0.0083) and preserved bimatoprost (2.68 +/- 0.67, p = 0.0041). There were no relevant between-group differences in mean tear meniscus height and break-up time. Ocular symptoms and conjunctival hyperaemia improved when preserved prostaglandin analogues were switched to preservative-free latanoprost for 6 months while intraocular pressure reduction was maintained. CONCLUSION: Overall, this study suggests a better subjective and objective ocular tolerance when patients were treated with preservative-free latanoprost than with other preserved prostaglandin analogues monotherapy. Switching to preservative-free latanoprost maintained intraocular pressure at the same level as preservative prostaglandin analogue, but improved ocular surface tolerance. PMID- 30301371 TI - Pre-exposure prophylaxis sorting among men who have sex with men. AB - Factors such as race, masculinity, and sexually transmitted infections have been documented to influence partner selection in men who have sex with men (MSM). Pre exposure prophylaxis (PrEP) has received mixed evaluations as a responsible step in HIV prevention and as an enabler of risker sexual practices. PrEP may consequently serve as an additional factor in partner choice. We examine the role that PrEP use and "promiscuity" play in affiliation and dating decisions by men who have sex with men with different HIV and PrEP stati. We invited 450 MSM across the United States from a smartphone geo-locating sex application to complete a survey of which 339 successfully finished the task. The survey contained vignettes of fictional men who were promiscuous or monogamous and either taking PrEP or not. Participants provided responses on whether to affiliate with these characters in three social domains: as friends, dates, or sex partners. Neither PrEP nor promiscuity influenced friendship choices. There was a preference for dating monogamous characters. Critically, PrEP influenced sexual affiliations for HIV negative individuals who showed a preference for PrEP using characters. The pattern of results provides quantitative evidence for PrEP based sexual sorting aimed at reducing risk of HIV transmission. PMID- 30301372 TI - Beyond BCG: the approaching era of personalised bladder-sparing therapies for non muscle-invasive urothelial cancers. AB - Progress in the management of non-muscle invasive bladder cancer has been slow. Despite longstanding use of intravesical therapies (e.g., Bacille Calmette Guerin, BCG) to complement cystoscopic resection of high-grade lesions, many patients still develop recurrences requiring cystectomy, while others suffer side effects of BCG without definite benefit. Many questions remain: for example, how many patients receive intravesical prophylaxis without efficacy? Which high-risk patients are best managed with early cystectomy? Could systemic therapies and/or radiotherapy extend bladder preservation times? Such questions may soon be refined by clinicopathologic non-muscle invasive bladder cancer signatures that predict sensitivity to cytotoxic, immune and targeted therapies. Hypothesis-based trials using these signatures should lead to more rational adjuvant treatments, longer bladder preservation times, and better quality of life for patients. PMID- 30301373 TI - Hypersensitivity and infusion-site adverse events with intravenous fosaprepitant after anthracycline-containing chemotherapy: a retrospective study. AB - AIM: Fosaprepitant, an intravenous neurokinin-1 receptor antagonist for chemotherapy-induced nausea and vomiting, contains polysorbate 80, which is associated with infusion-site adverse events (ISAEs) and hypersensitivity systemic reactions (HSRs). This study investigated ISAEs/HSRs following fosaprepitant with anthracycline-containing chemotherapy. PATIENTS & METHODS: This retrospective chart review noted ISAEs/HSRs following the anthracycline doxorubicin+cyclophosphamide and a three-drug fosaprepitant regimen, via peripheral line. RESULTS: 35/127 patients (28%) developed ISAEs/HSRs with chemotherapy and antiemetic therapy: 32 developed 137 individual ISAEs, primarily erythema, pain and catheter-site swelling; 16 developed 50 individual HSRs, primarily edema/swelling, erythema or dermatitis (no anaphylaxis). CONCLUSION: Fosaprepitant is associated with a significant ISAE/HSR rate following anthracycline-containing chemotherapy via peripheral line. Polysorbate 80-free intravenous neurokinin-1 receptor antagonist may provide a safer chemotherapy induced nausea and vomiting prophylaxis option. PMID- 30301374 TI - Optical coherence tomography angiography findings in a case with acute posterior multifocal placoid pigment epitheliopathy. AB - Twenty-six-year-old male patient admitted to the outpatient clinic with a complaint of decreased vision in both eyes. Visual acuity was 2/10 in the right and 7/10 in the left eye. Fundus examination revealed bilateral yellow-white subretinal lesions involving the macula. Fluorescein angiography showed hypofluorescent lesions in early and hyperflourescent lesions in the late phase. Optical coherence tomography angiography performed in the acute phase showed bilateral hypofluorescency at the choriocapillary level. A diagnosis of acute posterior multifocal placoid pigment epitheliopathy was given. After steroid treatment, visual acuity was improved to 10/10 and earlier lesions in optical coherence tomography angiography were found to be reduced. In conclusion, optical coherence tomography angiography is a noninvasive imaging technique that can be used in the diagnosis and follow-up of acute posterior multifocal placoid pigment epitheliopathy. PMID- 30301375 TI - Optimal Allocation of Interviews to Baseline and Endline Surveys in Place-Based Randomized Trials and Quasi-Experiments. AB - BACKGROUND: Many place-based randomized trials and quasi-experiments use a pair of cross-section surveys, rather than panel surveys, to estimate the average treatment effect of an intervention. In these studies, a random sample of individuals in each geographic cluster is selected for a baseline (preintervention) survey, and an independent random sample is selected for an endline (postintervention) survey. OBJECTIVE: This design raises the question, given a fixed budget, how should a researcher allocate resources between the baseline and endline surveys to maximize the precision of the estimated average treatment effect? RESULTS: We formalize this allocation problem and show that although the optimal share of interviews allocated to the baseline survey is always less than one-half, it is an increasing function of the total number of interviews per cluster, the cluster-level correlation between the baseline measure and the endline outcome, and the intracluster correlation coefficient. An example using multicountry survey data from Africa illustrates how the optimal allocation formulas can be combined with data to inform decisions at the planning stage. Another example uses data from a digital political advertising experiment in Texas to explore how precision would have varied with alternative allocations. PMID- 30301376 TI - Psychometric Testing of the Evidence-Based Practice Nursing Leadership Scale and the Work Environment Scale After Cross-Cultural Adaptation in Mainland China. AB - Implementation and sustainability of the evidence-based practice (EBP) approach within systems of health-care delivery require leadership and organizational support, yet few instruments have been developed specifically in Mainland China. The purpose of this study was to adapt the EBP Nursing Leadership Scale and the EBP Work Environment Scale to Mainland China's cultural context and to evaluate the psychometric properties of the newly adapted Chinese version. A pilot study was conducted in Mainland China with 25 clinical nurses. A subsequent validation study was conducted with 419 nurses from Mainland China. A content validity index of .985 and .982 was achieved. The split-half coefficient was .890 for the EBP Nursing Leadership Scale and .892 for the EBP Work Environment Scale. Test-retest reliability was .871 and .855, respectively. Principal component analysis resulted in a one-factor structure explaining 62.069% of the total variance for the EBP Nursing Leadership Scale and 62.242% of the total variance for the EBP Work Environment Scale. Both of the newly cross-culturally adapted scales possess adequate internal consistency and test-retest reliability and validity and therefore may be utilized in health-care environments to assess leadership and organizational support for EBP in Mainland China.

AB - N-Alkylaminoethanols, N,N'-dialkylaminoethanols, and triethanolamine are the hydrolyzed products or precursors of V-agents/nitrogen mustards. These compounds are prone to undergo oxidation in environmental matrices. Detection of the oxidized products provides a clue for the presence of parent amine compounds and it is an important task in the verification process of chemical weapons convention. Gas chromatography/mass spectrometry is the technique of choice for the detection of most of the chemical warfare agents; however, it is ideal to develop gas chromatography/mass spectrometry techniques for all the possible degradation products of chemical warfare agents as well. In general, the N-oxides of amines are expected to be thermally unstable; hence, the gas chromatography/mass spectrometry analysis of the N-oxides of triethanolamine, N alkyldiethanolamines and N,N'-dialkylaminoethanols is not explored. In this study, the N-oxides of chemical weapons convention-related aminoethanols (13 compounds) were successfully silylated and then analyzed by gas chromatography/mass spectrometry under electron ionization and chemical ionization techniques. The electron ionization mass spectra showed abundant molecular ions and structure indicative fragment ions including [M (O+CH2CH2OH)]+. The alkyl groups attached to nitrogen resulted in structure specific fragment ions that enable differentiation of isomeric compounds. The methane/chemical ionization spectra showed considerably abundant [M+H]+ (>10%) and the expected adduct ions. The retention indices of all the compounds were calculated using Van den Dool's formula. The gas chromatography/mass spectrometry data together with retention index values could be used for unambiguous identification of the N-oxides of aminoethanols during off-site analysis or proficiency tests.

PMID- 30301379 TI - New daily persistent headache (NDPH) triggered by a single Valsalva event: A case series. AB - Objective To describe a new subtype of new daily persistent headache that is triggered by a single Valsalva event. Methods A case series of patients was evaluated in an academic headache clinic over a 3-year time period. Results A total of seven patients (four female and three male) were diagnosed with this new subtype of new daily persistent headache. The headaches all began after a single Valsalva event. Average age at time of headache onset was 41 years (males: 39 years; females: 43 years) with an age range of 20-62 years. All patients developed their syndrome during the months of September to February with November and February being the most cited months (5/7 patients). Immediate worsening in the Trendelenburg position occurred in all patients and appeared to be an almost diagnostic test for the syndrome. No patient had papilledema on funduscopic exam. Five out of seven patients had no prior headache history including cough, exercise or migraine. Four of seven patients were of normal weight, while one was overweight and two were obese. A crowded posterior fossa was identified in five of seven patients on brain MRI. On cerebrospinal fluid pressure/volume lowering medication (acetazolamide, indomethacin and/or spironolactone), five out of seven patients achieved 90% plus improvement in headache frequency while three patients became pain free. Three patients were able to taper off medication without headache recurrence. Conclusion New daily persistent headache after a single Valsalva event appears to be a unique subtype of new daily persistent headache that is responsive to cerebrospinal fluid pressure/volume lowering medications. An abnormal reset of cerebrospinal fluid pressure/intracranial pressure to an elevated state is the presumed pathogenesis and may relate to the patient's baseline neuroanatomy of a crowded posterior fossa. There appears to be a circadian periodicity to the onset of the syndrome. Worsening in the Trendelenburg position is a probable diagnostic test. Defining new daily persistent headache subtypes by triggering event appears to be making a positive inroad in the understanding of this condition and helps present new effective therapies. PMID- 30301381 TI - Predictive value of laryngeal adductor reflex testing in patients with dysphagia due to a cerebral vascular accident. AB - PURPOSE: To determine the relationship between air pulse vs. touch laryngeal adductor reflex (LAR) tests and the clinical sensory findings of fiberoptic endoscopic evaluations of swallowing. METHOD: A retrospective review was conducted for 43 patients with dysphagia due to stroke that underwent fiberoptic endoscopic evaluation of swallowing with sensory testing (FEESST). Each patient received LAR testing using air pulse or touch methodologies. Clinically, responsiveness to pharyngeal residue and responsiveness to penetration or aspiration were analysed. RESULT: The sensitivity, specificity, positive and negative predictive values for both LAR test groups indicate that LAR testing did not effectively predict sensory function during the clinical swallow evaluation. Across both LAR groups, specificity values were higher than sensitivity values. In fact, the specificity values for the light touch LAR test group were extremely high, but the negative predictive values did not support those findings. Sensitivity and positive predictive values were low for both groups. CONCLUSION: Although LAR testing provides valuable information regarding laryngeal sensory discrimination, the results of the current study suggest that a clinical evaluation of swallowing is critical for effectively assessing the way in which patients utilise sensory information during swallowing. PMID- 30301380 TI - Correlations among brain and spinal MRI findings in spontaneous intracranial hypotension. AB - OBJECTIVES: Several brain and spinal magnetic resonance imaging signs have been described in spontaneous intracranial hypotension. Their correlations are not fully studied. This study aimed to explore potential mechanisms underlying cerebral neuroimaging findings and to examine associations among spinal and brain magnetic resonance imaging signs. METHODS: We conducted a retrospective review of magnetic resonance myelography and brain magnetic resonance imaging records of patients with spontaneous intracranial hypotension. Categorical principal component analysis was employed to cluster brain neuroimaging findings. Spearman correlation was employed to analyze associations among different brain neuroimaging findings and between brain and spinal neuroimaging findings. RESULTS: In patients with spontaneous intracranial hypotension (n = 148), categorical principal component analysis of brain neuroimaging signs revealed two clusters: Cerebral venous dilation and brain descent. Among all brain magnetic resonance imaging signs examined, only midbrain-pons angle associated with anterior epidural cerebrospinal fluid collection length (surrogate spinal cerebrospinal fluid leak severity) (n = 148, Spearman's rho = -0.38, p < .001). Subgroup analyses showed that the association between midbrain-pons angle (within brain descent cluster) and spinal cerebrospinal fluid leak severity was presented in patients with convex margins of the transverse sinuses (n = 122, Spearman's rho = -0.43, p < .001), but not in patients without convex margins (n = 26, Spearman's rho = -0.19, p = .348). The association between severity of transverse sinus distension and spinal cerebrospinal fluid leak severity was only presented in patients without convex margins (n = 26, Spearman's rho = 0.52, p = .006). CONCLUSION: This study indicates that there are two factors behind the brain neuroimaging findings in spontaneous intracranial hypotension: Cerebral venous dilation and brain descent. Certain brain neuroimaging signs correlate with spinal cerebrospinal fluid leakage severity, depending on different circumstances. PMID- 30301382 TI - Novel technology for mobility and balance tracking in patients with multiple sclerosis: a systematic review. AB - INTRODUCTION: Mobility and balance impairments in patients with multiple sclerosis (MS) are major factors for decreased quality of life. Novel sensing technologies have great potential to efficiently capture subtle changes in mobility and balance performance, and thus improve current practices by providing an easy-to-implement, objective, and continuous functional tracking in MS population. Areas covered: This review details the collective findings of novel technology utilization in mobility and balance tracking in patients with MS. Thirty-three were systematically identified and included in this review. Pertinent methodological features (participant demographics, sensing technology, study aims, functional assessment protocols, and outcome measures) were extracted from each article. The construct validity, reliability, clinical relevance, and discriminative ability of sensor-based assessment in the MS population were summarized. Expert commentary: Sensor-based balance and mobility assessment are valid in comparison with reference standard techniques and are reliable to measure performance in the MS population. Sensor-based measures are also associated with validated clinical outcomes and are sensitive to functional deficits in individuals with MS. Such technologies may greatly improve the likelihood of detecting mobility and balance dysfunctions in real-world environments, thus allowing healthcare professionals to monitor interventions and manage disease progression precisely and efficiently Abbreviations: PwMS: Patients with Multiple Sclerosis; BBS: Berg Balance Scale; DGI: Dynamic Gait Index; ABC: Activity-specific Balance Confidence; T25FW: Timed 25 Foot Walk; 6MWT: 6 minute walk test; TUG: Timed Up and Go test; EO: Eyes Open; EC: Eyes Closed; ICC: Intraclass Correlation Coefficient; EDSS: Expanded Disability Status Scale; MFIS: Modified Fatigue Impact Scale; MSWS: Multiple Sclerosis Walking Scale; MSIS: Mutliple Sclerosis Impact Scale; PPA: Physiological Profile Assessment; HC: Healthy Control; AP: Anterior-posterior direction; ML: Mediolateral direction. PMID- 30301383 TI - Serum neopterin levels in women with preeclampsia: a systematic review. AB - OBJECTIVE: Neopterin is a pteridine that is produced following activation of human macrophages upon stimulation with the cytokine interferon-gamma. Several studies suggest its association with preeclampsia and the purpose of the present study is to evaluate this assumption. METHODS: We searched the Medline (1992 2018), Scopus (1993-2018) and Google Scholar (1993-2018) databases. All articles that evaluated serum neopterin levels in patients with preeclampsia were held eligible for inclusion, regardless of the trimester of pregnancy in which the measurement was performed. Case reports, animal studies and previous reviews were excluded. RESULTS: A total of 10 studies were finally included in the present review, with a total number of 3,529 pregnant women. Among them 446 were diagnosed with preeclampsia. The majority of included studies reported that serum neopterin was significantly higher in patients with preeclampsia, compared to normotensive pregnant women (p < .05). One study reported that serum levels seem to correlate with the severity of the disease; as patients with HELLP had significantly higher values of neopterin compared to patients with mild and severe preeclampsia. None of the included studies proposed a cut-off value that would help assess the predictive accuracy of this protein for the detection of preeclampsia. CONCLUSION: Although current data seem to be promising, neopterin remains far from being used in current clinical practice as a biomarker that would help predict and follow-up patients that develop preeclampsia. Future studies are needed, to determine the optimal timing for its measurement and to propose potential cut-off values that would help in this direction. PMID- 30301385 TI - Physiologically-based pharmacokinetic modeling for mirabegron: a multi elimination pathway mediated by cytochrome P450 3A4, uridine 5'-diphosphate glucuronosyltransferase 2B7, and butyrylcholinesterase. AB - This was the first study to construct a physiologically-based pharmacokinetic (PBPK) model for mirabegron which incorporates the overall elimination pathways of metabolism by cytochrome P450 (CYP) 3A4, uridine 5'-diphosphate glucuronosyltransferase (UGT) 2B7, and butyrylcholinesterase (BChE) and renal excretion. The objective was to assess the risk of drug-drug interactions (DDIs) by estimating the contribution of each elimination pathway and simulating the magnitude of the DDIs with UGT2B7 inhibitors. A PBPK model for mirabegron was constructed to reproduce the plasma concentration-time curves from a phase 1 study and the magnitude of the DDI with ketoconazole taking into account the overall elimination pathways. The PBPK model was subsequently verified using data from other DDI studies. The constructed PBPK model estimated the contribution for each elimination pathway: 44% and 29% for CYP3A4 and UGT2B7 in the liver, 1.6% for UGT2B7 in the kidney, 3.2% for BChE in plasma, and 22% for renal excretion. Co-administration of probenecid (an UGT2B7 inhibitor) or fluconazole (an UGT2B7 and CYP3A4 inhibitor) was predicted to increase area under the curve for mirabegron to 115% or 174%, respectively. In conclusion, PBPK modeling and simulation revealed a low DDI risk for mirabegron following co-administration with BChE or UGT2B7 inhibitors. PMID- 30301384 TI - Speech-driven mobile games for speech therapy: User experiences and feasibility. AB - PURPOSE: To assist in remote treatment, speech-language pathologists (SLPs) rely on mobile games, which though entertaining, lack feedback mechanisms. Games integrated with automatic speech recognition (ASR) offer a solution where speech productions control gameplay. We therefore performed a feasibility study to assess children's and SLPs' experiences towards speech-controlled games, game feature preferences and ASR accuracy. METHOD: Ten children with childhood apraxia of speech (CAS), six typically developing (TD) children and seven SLPs trialled five games and answered questionnaires. Researchers also compared the results of ASR to perceptual judgment. RESULT: Children and SLPs found speech-controlled games interesting and fun, despite ASR-human disagreements. They preferred games with rewards, challenge and multiple difficulty levels. Automatic speech recognition-human agreement was higher for SLPs than children, similar between TD and CAS and unaffected by CAS severity (77% TD, 75% CAS - incorrect; 51% TD, 47% CAS, 71% SLP - correct). Manual stop recording yielded higher agreement than automatic. Word length did not influence agreement. CONCLUSION: Children's and SLPs' positive responses towards speech-controlled games suggest that they can engage children in higher intensity practice. Our findings can guide future improvements to the ASR, recording methods and game features to improve the user experience and therapy adherence.

PMID- 30301386 TI - Factors associated with early and late failure after goniotomy for primary pediatric glaucoma. AB - PURPOSE: To analyze the risk factors associated with early and late failure after goniotomy for primary pediatric glaucoma. METHODS: A retrospective study was done on infants who underwent goniotomy as the initial surgical procedure for primary pediatric glaucoma, and had a follow-up period ?48 months after surgery. Early and late failures were defined as intraocular pressure ?18 mmHg or signs of glaucoma progression before and after the end of first year, respectively. RESULTS: A total of 81 eyes of 47 children were included. The mean age at the time of surgery was 6.1 +/- 6.7 months, 34 children (72.3%) were bilateral. The mean follow-up was 5.9 +/- 2.8 years. Of the included eyes, 41 eyes (50.6%) showed success, 25 eyes (30.9%) showed an early failure, and 15 eyes (18.5%) showed a late failure. The mean survival time was 43 months. However, only surgery before the end of the first month and positive consanguinity of the parents (P < 0.01 for both) were independent risk factors for early and late failure of goniotomy for primary pediatric glaucoma. Patients with late failure showed a statistically significant lower preoperative intraocular pressure (P = 0.02). A larger preoperative corneal diameter and a male gender were associated with higher but statistically insignificant failure rates. There were no differences in the early or late failure rates between unilateral and bilateral cases. CONCLUSION: A positive consanguinity of the parents and surgery before the end of the first month are the major predictors of failure of goniotomy.

PMID- 30301388 TI - 3,3'-Diindolylmethane enhances apoptosis in docetaxel-treated breast cancer cells by generation of reactive oxygen species. AB - CONTEXT: A major problem in the treatment of cancer is the development of toxic side effects and resistance to chemotherapy. The use of plant compounds to overcome resistance and prevent toxicity is a potential strategy for treatment. OBJECTIVE: We evaluated whether 3,3'-diindolylmethane (DIM) enhanced the sensitivity of breast cancer cells to docetaxel (DOC). MATERIALS AND METHODS: MDA MB231 and Sk-BR-3 cells were treated with and without 25 or 50 uM of DIM and 1 nM of DOC for 48 and 72 h, respectively. MTT assay was used to measure cell survival. Apoptosis and intracellular reactive oxygen species (ROS) were determined by flow cytometry. The expression of proteins regulating ROS production and apoptosis was evaluated by immunoblotting technique. RESULTS: Combining 25 uM of DIM with 1 nM DOC decreased cell survival by 42% in MDA-MB231 cells and 59% in Sk-BR-3 cells compared to control, DIM, or DOC (p <= 0.05). The combination treatment increased apoptosis over 20% (p <= 0.01) in both cell lines, which was associated with decreased Bcl-2, increased Bax, cleaved PARP and activated JNK (p <= 0.01). ROS production increased by 46.5% in the MDA-MB231 and 29.3% in Sk-BR-3 cells with the combination compared to DIM or DOC alone. Pretreating cells with N-acetyl-cysteine or Tiron abrogated the anti-survival effect of the combination. The increase in ROS was associated with a 54% decrease in MnSOD and 47% increase in NOX2 protein compared to the other groups. CONCLUSIONS: Our findings indicated that DIM enhances the sensitivity of breast cancer cells to DOC treatment by increasing ROS, which led to decreased cell survival and apoptosis.

PMID- 30301390 TI - Dicranopteris linearis extract inhibits the proliferation of human breast cancer cell line (MDA-MB-231) via induction of S-phase arrest and apoptosis. AB - CONTEXT: Dicranopteris linearis (Burm.f.) Underw. (Gleicheniaceae) has been scientifically proven to exert various pharmacological activities. Nevertheless, its anti-proliferative potential has not been extensively investigated. OBJECTIVE: To investigate the anti-proliferative potential of D. linearis leaves and determine possible mechanistic pathways. MATERIALS AND METHODS: MTT assay was used to determine the cytotoxic effects of D. linearis methanol (MEDL) and petroleum ether (PEEDL) extracts at concentrations of 100, 50, 25, 12.5, 6.25 and 3.125 ug/mL against a panel of cancer cell lines (breast [MCF-7 and MDA-MB-231], cervical [HeLa], colon [HT-29], hepatocellular [HepG2] and lung [A549]), as compared to negative (untreated) and positive [5-fluorouracil (5-FU)-treated] control groups. Mouse fibroblast cells (3T3) were used as normal cells. The mode of cell death was examined using morphological analysis via acridine orange (AO) and propidium iodide (PI) double staining. Cell cycle arrest was determined using flow cytometer, followed by annexin V-PI apoptosis detection kit. RESULTS: MEDL demonstrated the most significant growth inhibition against MDA-MB-231 cells (IC50 22.4 ug/mL). PEEDL showed no cytotoxic effect. Induction of apoptosis by MEDL was evidenced via morphological analysis and acridine orange propidium iodide staining. MEDL could induce S phase cell cycle arrest after 72 h of incubation. Early apoptosis induction in MDA-MB-231 cells was confirmed by annexin V-FITC and PI staining. Significant increase in apoptotic cells were detected after 24 h of treatment with 15.07% cells underwent apoptosis, and the amount escalated to 18.24% with prolonged 48 h incubation. CONCLUSIONS: MEDL has potential as a potent cytotoxic agent against MDA-MB-231 adenocarcinoma. PMID- 30301392 TI - Vocational support in mental health service delivery in Australia. AB - BACKGROUND: Individuals experiencing severe and persistent mental illness report a desire to gain and sustain work. Individual Placement and Support (IPS) is an evidence-based approach to vocational rehabilitation to support competitive employment outcomes. AIM/OBJECTIVE: This study aimed to evaluate whether a joint governance management partnership, between a clinical adult mental health and an employment service, could deliver a sustained IPS program in Australia. MATERIALS AND METHOD: The methodology entailed a Clinical Data Mining approach, to examine records from seven years of implementation of IPS in one setting within an Australian public mental health service context. RESULTS/FINDINGS: Despite the prevalence of schizophrenia spectrum diagnoses and an older mean age (39 years), indicating that a large proportion of the cohort had experienced serious mental illness for over twenty years, findings were that 46.3% of participants achieved employment. CONCLUSIONS: This is an excellent result and is comparable to the only randomised control trial, with adult services, in the Australian context, which found a 42.5% employment rate possible under IPS compared with just 23.5% with referral to external employment services. SIGNIFICANCE: More extensive trialling of IPS across clinical services is required, in Australia and internationally, including fidelity protocols, for knowledge translation to be achieved.

A scoping review to identify the active ingredients of therapeutic and supported playgroups. AB - BACKGROUND: Supported and therapeutic playgroups aim to support and strengthen vulnerable children and families by increasing parenting capacity, parent-child interaction, enhancing child outcomes and promoting community networks. This review aimed to comprehensively scope the literature to identify the "active ingredients" of supported and therapeutic playgroups. METHOD: A systematic search of grey and scholarly literature was conducted using Medline, PyschINFO, EMBASE, ERIC, CINAHL, MedNar, Informit, Scopus, Libraries of Australia and Trove. Articles were included if they: i) defined playgroup as a group of children and actively involved caregivers; ii) described a therapeutic playgroup or supported playgroup model; iii) targeted children prior to school age; and iv) measured the impact of playgroups. A total of 36 articles met the inclusion criteria. Qualitative data was synthesised using a meta-ethnography approach with findings charted against a conceptual model of engagement. Quantitative data was synthesised using descriptive statistics. RESULTS: The findings identified that emotional, practical and informational components of playgroups strongly reflect family centred practice, self-efficacy theory and peer-support principles. CONCLUSION: Therapeutic and supported playgroups are complex interventions, with numerous interacting components that make them beneficial for children and families. This review is the first to identify the "active ingredients" of playgroups with findings informing the design of future playgroups for vulnerable children and families.

PMID- 30301396 TI - Expression of TLE1 in Malignant Melanoma With Spindle Cell Morphology: A Potential Diagnostic Pitfall. AB - OBJECTIVES: Transducer-like enhancer of split 1 (TLE1) immunohistochemistry is widely used as a biomarker of synovial sarcoma. Spindle cell or desmoplastic melanoma can morphologically mimic synovial sarcoma. The aim of this study was to investigate the expression of TLE1 in melanomas with a spindle cell morphology. METHODS: A search of the surgical pathology files resulted in 57 cases of melanomas diagnosed with a spindle cell or desmoplastic component. After review, 8 cases had no definitive dermal spindle cell component and 7 cases had insufficient tissue remaining and were excluded from the study. A total of 42 melanomas were examined for TLE1 immunohistochemistry using a mouse monoclonal antibody (Cell Marque, clone 1F5). Strength and percentage of nuclear TLE1 positivity was graded on a scale from 0 to 3+. Staining for TLE1 was considered positive for 2 to 3+ and negative for 0 to 1+. RESULTS: Nuclear TLE1 expression was identified in 24 (57%) of the 42 melanoma cases with spindle cell morphology (2+, n = 14; 3+, n = 10). TLE1 was considered negative in 18 cases (43%), of which most contained weak staining (1+, n = 14 [33%]) and only a small subset did not show any staining (0, n = 4 [10%]). CONCLUSION: TLE1 frequently highlights melanomas with spindle cell morphology and is a potential diagnostic pitfall. Therefore, when evaluating spindle cell tumors in which the differential may include both a melanoma and synovial sarcoma, TLE1 expression should be interpreted with caution and in conjunction with an immunohistochemical panel. PMID- 30301397 TI - Everyday activities outside the home are a struggle: Narratives from two persons with acquired brain injury. AB - BACKGROUND: Participation restriction is a common consequence after acquired brain injury (ABI). AIM: To explore and identify problematic situations in everyday activities outside the home for persons with acquired brain injury. MATERIAL AND METHOD: Two persons of working age with ABI were included. Data were generated through repeated semi-structured interviews and participant observations. Narrative analysis was used to capture ongoing processes related to problematic situations during engagement in everyday activities outside the home. RESULTS: The narratives reflect how places, everyday activities and social relations were closely connected and influenced engagement in everyday activities outside the home. The participants visited fewer places and performed more of their everyday activities alone in their homes after the injury compared to before. They were struggling to create meaning in their lives and trying to reformulate their identity. Problematic situations often occurred outside the home as a result of unexpected events. The narratives indicate a struggle to find new routines to handle challenging situations. CONCLUSIONS: The results provide an understanding of how problematic situations occurred and were managed in different ways. By observing everyday situations professionals can gain access to how persons with ABI act in and reflect upon problematic situations which can eventually improve the design of individually tailored interventions. PMID- 30301398 TI - Re-examining insulin compared to non-insulin therapies for type 2 diabetes: when in the disease trajectory is insulin preferable? AB - In patients with type 2 diabetes secondary to excess nutrients and energy balance, relative - not absolute - insulin deficiency plays a key role in disease development and progression. Although patients with type 2 diabetes who have features of insulin resistance would usually have hyperinsulinemia, insulin therapy remains recommended by guidelines particularly when patients fail to achieve glycemic goals. This approach does not prevent complications particularly macrovascular complications. This raises a controversial question regarding the benefit of using exogenous insulin for glycemic control in patients with type 2 diabetes who have features of insulin resistance. To address this concern, the authors performed a literature search looking for either randomized trials or meta-analyses directly comparing exogenous insulin to non-insulin therapy in the treatment of patients with type 2 diabetes. Our main outcomes of interest were effect on glycemic control and insulin resistance at various time points in the usual trajectory of type 2 diabetes. In trials investigating early short-term initiation of intensive insulin therapy, insulin therapy was beneficial in rapidly achieving glycemic control and reversing glucotoxicity. Following the initial 2 weeks to 3 months of adequate glycemic control in patients on intensive insulin therapy, there is little evidence that continuing insulin therapy provides greater glycemic control or improves insulin resistance beyond what can be achieved with other therapies. In conclusion, long-term insulin use appears neutral if not potentially harmful with respect to insulin resistance and cardiovascular outcomes. While this review has limitations and should be dealt cautiously, it raises questions regarding the benefit of insulin in patients with type 2 diabetes with features of insulin resistance. Further research is needed to confirm these findings. PMID- 30301400 TI - Undergraduate anesthetic education: Medical students' perspectives. PMID- 30301399 TI - Clinical and biological characteristics of acute myeloid leukemia with 20-29% blasts: a retrospective single-center study. AB - It is controversial whether acute myeloid leukemia (AML) patients with 20-29% bone marrow (BM) blasts should be considered AML or myelodysplastic syndromes (MDS). We retrospectively studied 382 patients, including 108 AML with 20-29% BM blasts (AML20-29), 210 AML with >=30% BM blasts (AML >= 30), and 64 MDS with 10 19% BM blasts (MDS-EB2). We found that AML20-29 were more similar to MDS-EB2 in terms of advanced age, less blood count, the increased presence of poor-risk cytogenetics. The frequency of mutated genes in AML20-29 had both the characters of AML and MDS. Median overall survival of AML20-29 and MDS-EB2 were similar and shorter than those of AML >= 30 (p = .045). Multivariate analysis showed inferior survival with increased age, low platelet count and FLT3 mutations. Our findings suggest that AML20-29 have clinical features more similar to MDS than AML. PMID- 30301401 TI - Autophagy determines mtDNA copy number dynamics during starvation. AB - Derived from bacterial ancestors, mitochondria have maintained their own albeit strongly reduced genome, mitochondrial DNA (mtDNA), which encodes for a small and highly specialized set of genes. MtDNA exists in tens to thousands of copies packaged in numerous nucleoprotein complexes, termed nucleoids, distributed throughout the dynamic mitochondrial network. Our understanding of the mechanisms of how cells regulate the copy number of mitochondrial genomes has been limited. Here, we summarize and discuss our recent findings that Mip1/POLG (mitochondrial DNA polymerase gamma) critically controls mtDNA copy number by operating in 2 opposing modes, synthesis and, unexpectedly, degradation of mtDNA, when yeast cells face nutrient starvation. The balance of the 2 modes of Mip1/POLG and thus mtDNA copy number dynamics depends on the integrity of macroautophagy/autophagy, which sustains continuous synthesis and maintenance of mtDNA. In autophagy deficient cells, a combination of nucleotide insufficiency and elevated mitochondrial ROS production impairs mtDNA synthesis and drives mtDNA degradation by the 3'-5'-exonuclease activity of Mip1/POLG resulting in mitochondrial genome depletion and irreversible respiratory deficiency. Abbrivations: mtDNA: mitochondrial DNA; mtDCN: mitochondrial DNA copy number. PMID- 30301402 TI - Viewpoints on how students with autism can best navigate university. AB - BACKGROUND: Despite recognition of the challenges faced by students with autism spectrum disorders (ASD) there is limited understanding of the barriers and facilitators to participation in major life areas, such as being a university student. AIM/OBJECTIVE: This research aimed to examine viewpoints on what affects the success of Australian university students with ASD. MATERIAL AND METHOD: Q methodology was used to describe the viewpoints of university students with ASD, their parents and their mentors, on success at university for students with ASD. A total of 57 participants completed the Q-sort. RESULTS/FINDINGS: Three viewpoints emerged; Individualised Support, Contextual Support and Social Support. CONCLUSIONS: This study highlighted that supports need to be individualized to the barriers and facilitators faced by Australian students with ASD. Supports also need to be contextualized to the built and social environments of universities. SIGNIFICANCE: This study supports the premise that environmental interventions can be effective in facilitating participation in major life areas, such as university education. Peer mentoring for students with ASD may have utility for this group, but should be extended to include social, emotional and psychological support. PMID- 30301403 TI - ASXL1 is a molecular predictor in idiopathic cytopenia of undetermined significance. AB - We analyzed the mutational profile of idiopathic cytopenia of undetermined significance (ICUS) compared with that of myelodysplastic syndrome (MDS). Targeted sequencing of 88 genes associated with myeloid malignancies was performed using samples of bone marrow mononuclear cells from ICUS and MDS patients. Forty patients with ICUS and 128 patients with MDS were included in this study. The median mutational burden was 0.7 mutation/person in the ICUS group and 2.2 mutation/person in the MDS group. ASXL1 (seven patients) was the most frequently mutated gene. ASXL1 was an independent significant prognostic factor for event-free survival (EFS) and overall survival (OS) (hazard ratio (HR) = 10.07 and 30.63, p = .004 and .003, respectively). The ASXL1 mutation which is frequently detected in elderly patients is a molecular predictor for pancytopenia and survival in patients with ICUS. A larger prospective study is needed to validate the role of this genetic mutation in an ICUS prognosis. PMID- 30301406 TI - Phase I and phase II metabolism simulation of antitumor-active 2 hydroxyacridinone with electrochemistry coupled on-line with mass spectrometry. AB - 1. Here, we report the metabolic profile and the results of associated metabolic studies of 2-hydroxyacridinone (2-OH-AC), the reference compound for antitumor active imidazo- and triazoloacridinones. 2. Electrochemistry coupled with mass spectrometry was applied to simulate the general oxidative metabolism of 2-OH-AC for the first time. The reactivity of 2-OH-AC products to biomolecules was also examined. The usefulness of the electrochemistry for studying the reactive drug metabolite trapping (conjugation reactions) was evaluated by the comparison with conventional electrochemical (controlled-potential electrolysis) and enzymatic (microsomal incubation) approaches. 3. 2-OH-AC oxidation products were generated in an electrochemical thin-layer cell. Their tentative structures were assigned based on tandem mass spectrometry in combination with accurate mass measurements. Moreover, the electrochemical conversion of 2-OH-AC in the presence of reduced glutathione and/or N-acetylcysteine unveiled the formation of reactive metabolite nucleophilic trapping agent conjugates (m/z 517 and m/z 373, respectively) via the thiol group. This glutathione S-conjugate was also identified after electrolysis experiment as well as was detected in liver microsomes. 4. Summing up, the present work illustrates that the electrochemical simulation of metabolic reactions successfully supports the results of classical electrochemical and enzymatic studies. Therefore, it can be a useful tool for synthesis of drug metabolites, including reactive metabolites.

AB - BACKGROUND: Sedentary behaviors (SB) may exacerbate loss of muscle mass and function, independent of physical activity levels. This study examined the associations of SB with abdominal muscle area and density, a marker of muscle quality, in adults. METHODS: A total of 1895 participants from the Multi-Ethnic Study of Atherosclerosis completed detailed health history, physical activity and SB questionnaires, computed tomography to quantify body composition, and measurements of inflammatory markers. Analyses included linear and nonlinear regression. RESULTS: The mean age and body mass index were 64.6 years and 28 kg.m 2, respectively, and 50% were women. On average, participants engaged in 28 metabolic equivalent hours.week-1 of SB. With adjustment for age, sex, race/ethnicity, physical activity, cardiovascular disease risk factors, and inflammation, multivariable regression modeling revealed a nonlinear (quadratic) relationship between SB and locomotor, stability, and total abdominal muscle density (P < .01) but not muscle area. The SB inflection point at which locomotor, stability, and total abdominal muscle density began to decrease was 38.2, 39.6, and 39.2 metabolic equivalent hours.week-1 of SB, respectively. CONCLUSIONS: SB is associated with reduced muscle density when practiced as little as 5.5 metabolic equivalent hours.day-1. These findings may have important implications for SB guidelines for targeting skeletal muscle health in older adults.

AB - PURPOSE: To report an experimental study and clinical case using a coil packing technique that hastens occlusion of an Amplatzer Vascular Plug 1 (AVP1) in short segment embolization of high-flow target vessels. TECHNIQUE: An experimental vascular stenosis model was made of 12-mm soft polyvinyl chloride tubing. Under continuous pulsatile flow, a 12-mm AVP1 was deployed in the 4-mm-diameter stenosis. Before detachment of the AVP1, a 2.2-F microcatheter was inserted into the AVP1 through its mesh via a 6-F delivery guiding sheath in parallel with the delivery wire. Hydrogel microcoils were deployed tightly in the AVP1 and the plug was detached. After the procedure, the pulsatile saline flow was nearly obliterated. In the first clinical case, a 64-year-old man with a thoracic aortic stent-graft and single vessel debranching for type B aortic dissection developed a residual type II endoleak via the left subclavian artery. This coil packing technique in an AVP1 was employed to successfully embolize the leak. CONCLUSION: Based on the experimental study and the first experience in vivo, tight coil packing of an AVP1 might be a robust technique for ultrashort-segment embolization.

AB - Potassium currents determine the resting membrane potential and govern repolarisation in cardiac myocytes. Here, we review the various currents in the sinoatrial node focussing on their molecular and cellular properties and their role in pacemaking and heart rate control. We also describe how our recent finding of a novel ATP-sensitive potassium channel population in these cells fits into this picture. PMID- 30301408 TI - The effect of hydraulic retention time on ammonia and nitrate bio-removal over nitrite process. AB - Ammonia and Nitrate Bio-removal Over Nitrite (ANBON) is a new biological process, which couples denitratation with Anaerobic Ammonium Oxidation (ANAMMOX) to carry out simultaneous removal of nitrate nitrogen and ammonia nitrogen. The effect of hydraulic retention time (HRT) on the performance of ANBON process was investigated. The results showed that the optimal HRT was about 0.7 h and the nitrogen removal rate was 26.2 +/- 0.7 g N.L-1.d-1, which was at top level reported in previous literatures. The change of HRT was found to trigger the change of microbial community in the reactor, which exerted a great effect on the performance of ANBON process. The community analysis based on 16S rRNA gene indicated that Halomonas and Candidatus Kuenenia were the dominant functional bacteria in the denitratation unit and the ANAMMOX unit respectively. These results are helpful for the development and application of ANBON process. PMID- 30301409 TI - Implementation and evaluation of Stanford Health Care store-and-forward teledermatology consultation workflow built within an existing electronic health record system. AB - Introduction Teledermatology services that function separately from patients' primary electronic health record (EHR) can lead to fragmented care, poor provider communication, privacy concerns and billing challenges. This study addresses these challenges by developing PhotoCareMD, a store-and-forward (SAF) teledermatology consultation workflow built entirely within an existing Epic based EHR. Methods Thirty-six primary care physicians (PCPs) from eight outpatient clinics submitted 215 electronic consults (eConsults) for 211 patients to a Stanford Health Care dermatologist via PhotoCareMD. Comparisons were made with in-person referrals for this same dermatologist prior to initiation of PhotoCareMD. Results Compared to traditional in-person dermatology clinic visits, eConsults decreased the time to diagnosis and treatment from 23 days to 16 hours. The majority (73%) of eConsults were resolved electronically. In-person referrals from PhotoCareMD (27%) had a 50% lower cancellation rate compared with traditional referrals (11% versus 22%). The average in-person visit and documentation was 25 minutes compared with 8 minutes for an eConsult. PhotoCareMD saved 13 additional clinic hours to be made available to the dermatologist over the course of the pilot. At four patients per hour, this opens 52 dermatology clinic slots. Over 96% of patients had a favourable experience and 95% felt this service saved them time. Among PCPs, 100% would recommend PhotoCareMD to their colleagues and 95% said PhotoCareMD was a helpful educational tool. Discussion An internal SAF teledermatology workflow can be effectively implemented to increase access to and quality of dermatologic care. Our workflow can serve as a successful model for other hospitals and specialties.

AB - Organic micropollutants (OMP) in the household and industrial wastewater are not efficiently removed by conventional treatment processes and a significant fraction ends in sludge. Proper valorization technologies become fundamental to attain sustainable sewage sludge management, with anaerobic digestion (AD) as one of the preferred strategies. However, it exhibits some limitations that can be overcome with pre-treatment processes. In this study, the influence of different pre-treatment configurations over OMP concentration and removal during AD was assessed. The incorporation of a sequential US - TT-PT resulted in decreased concentrations of 7 of the 9 detected compounds in biosolids compared to conventional AD digestate, with bisphenol-A and ter-octylphenol showing the opposite effect. The results suggest that the assessed PT could improve the removal of sequestered or highly hydrophobic compounds through their solubilization and increased bioavailability. PMID- 30301412 TI - Caregiver ratings and performance-based indices of executive function among preschoolers with and without maltreatment experience. AB - Despite the well-documented impact of early maltreatment on children's executive function (EF), there has been limited consensus about how to best assess this neurocognitive domain in high-risk, vulnerable preschool-aged children. Relevant studies have generally utilized either performance-based tests or caregiver ratings of EF, yet multi-method research has been rare. This study examined the EF profiles of preschoolers exposed to maltreatment, as indexed by the Behavior Rating Inventory of Executive function - Preschool Version (BRIEF-P), and investigated associations between caregiver ratings and performance-based measures (Happy-Sad Stroop, Tapping Test, and Dimensional Change Card Sort - DCCS) of EF in this population. Maltreatment status was further tested as a moderator of associations between these measures. Participants were (n = 107) children aged 4-5 years (M = 4.75; SD = 0.57; 39% female), with various levels of exposure to maltreatment. Children exposed to maltreatment were found to exhibit significantly more caregiver-rated deficits in EF than non-maltreated children, with greater fluctuations apparent across all scales of the BRIEF-P. Consistent with previous research in neurologically impaired children, there were only limited and weak to moderate correlations between BRIEF-P scales and performance based measures of EF. Furthermore, maltreatment status was found to moderate the association between scores on the BRIEF-P Inhibit Scale and the DCCS, such that the association between these indices was weaker among children exposed to higher levels of maltreatment. PMID- 30301411 TI - An overview about the impact of Hinge Region towards the Anticancer Binding Affinity of the Ck2 Ligands- A Quantum Chemical Analysis. AB - Casein Kinase 2 (CK2) is extremely preserved and universally uttered serine/threonine kinase, vital for cellular feasibility. The present study was aimed to analyse the binding strength of CK2 ligands specifically in the hinge region, as it is aware that most of the existing drugs are targeted to bind the hinge of the corresponding protein. The analysis will give a clear picture about the role of hinge region with ligand, which will be useful for scientist community in drug designing. To predict the binding strength of CK2 ligands, the role of halogen bond, hydrogen bond interaction at the hinge region was depicted in detail through interaction energy calculations at M062Z/def2-QZVP level of theory. HOMO map plotted for CK2 ligands gives clear pictorial representation of orbital's, which induce for interaction. Ligand properties discussed in detail through Lipinski's five rules predict that almost all the ligands satisfy the rule, except 3KXG, which violates the Lipinski's two rules i.e molecular mass exceeds 500 Da i.e. 512.61 Da and log P value is high of 5.09. The natural bond orbital analysis deliberate that the hydrogen/halogen bonds figuring out within the complexes are observed to have moderate stabilization energy, but those hydrogen/halogen bonds that exist with close contacts have high stabilization energy. Overall this computational work will give an understandable depiction for modelling anticancer ligands along the hinge region in CK2 protein; also it will give a new path for the choice of side chains on the ligand. PMID- 30301413 TI - Changes in Smoking During Retirement Transition: A Longitudinal Cohort Study. AB - AIMS: We examined the effect of retirement transition on changes in smoking, identified trajectories of smoking around the retirement transition, and investigated factors predicting the membership in the trajectories. METHODS: This longitudinal cohort study included 1,432 current or former smokers who entered into statutory retirement in 2000-2011 and who filled out two to four questionnaires sent at four-year intervals. Effect of retirement on smoking was analysed as a non-randomized pseudo-trial in which we compared the likelihood of quitting and relapsing smoking between two subsequent survey waves among those who retired and did not retire. We used latent class analysis to identify trajectories of smoking status and smoking intensity (low: <10 cigarettes/day or high: ?10 cigarettes/day), and multinomial logistic regression models to assess pre-retirement factors associated with smoking trajectories. RESULTS: Retirement transition was associated with 1.7-fold odds of quitting smoking (95% confidence intervals 1.3-2.2) compared with no retirement transition. We identified three smoking status trajectories: 'sustained non-smoking' (61% of the participants), 'sustained smoking' (23%) and 'decreasing smoking' (16%). For 489 baseline smokers, we identified three smoking intensity trajectories: 'sustained high intensity smoking' (32% of the participants), 'sustained low intensity smoking' (32%) and 'decreasing high intensity smoking' (35%). Living outside an inner urban area predicted membership in the 'decreasing smoking' versus 'sustained smoking' trajectory. CONCLUSIONS: Smokers are more likely to quit smoking during transition to retirement than before or after it. Characteristics of the smoking environment may affect smoking behaviour around retirement.

AB - We investigated GDP (gemcitabine, 1000 mg/m2 IV d1, d8; dexamethasone, 40 mg po d1-4; cisplatin, 75 mg/m2 IV d1) combined with romidepsin on days 1 and 8 every 21 days to a maximum of six cycles in a standard 3 + 3, phase I dose escalation trial for patients with relapsed/refractory peripheral T-cell (PTCL) or diffuse large B-cell (DLBCL) lymphoma (NCT01846390). After treating four patients, gemcitabine and romidepsin were given on days 1 and 15 every 28 days. On the 21 day schedule at 6 mg/m2 romidepsin, there were three dose-limiting toxicities (DLTs) among four patients. On the 28-day schedule, there were no DLTs at the 6, 8, or 10 mg/m2 dose. At 12 mg/m2, there were four observed grade 3 DLTs among six evaluable patients. Full doses of GDP can be combined with a recommended phase II romidepsin dose of 10 mg/m2 if given on a day 1, 15 every 28 days schedule. PMID- 30301415 TI - Examining the relationship between performance-based and questionnaire assessments of executive function in young preterm children: Implications for clinical practice. AB - The aim of this study was to determine whether specific performance-based executive function assessment tools were associated with executive functioning in everyday life as reported by parents and teachers of four- to five-year-old preterm and term children. At the age of 4 years, 141 preterm children born <33 weeks' gestation and 77 term children were assessed using performance-based intelligence (WPPSI-III) and executive function (EF) assessment tools (NEPSY-II, Day-Night and Shape School tasks). The assessment results were compared with the parent and teacher completed questionnaires of EF (BRIEF-P) when the children started kindergarten at the age of 4 to 5 years. The performance-based intelligence and EF assessment results were not consistently associated with the parent and teacher reports of EF in everyday life for either preterm or term groups. Clinical implications of using and interpreting performance-based EF assessment tools and EF questionnaires are discussed with a particular focus on young preterm children at the commencement of formal schooling. PMID- 30301416 TI - The lived experience of people with intellectual disabilities in post-secondary or higher education. AB - The transformational role education plays in the lives of people with intellectual disabilities has not been fully examined. The purpose of this study was to explore and investigate the meanings people with intellectual disabilities construct of their experiences in post-secondary and higher education. Heideggerian hermeneutic phenomenology was the qualitative methodology adopted for the study. Individual interviews were conducted with 27 people with intellectual disabilities and analysed in stages. These stages included the creation of I-Poems offering a unique opportunity for individual participant voices to be heard. Three core themes emerged to describe living an authentic life: learning (with the emphasis on increased skills, independence and opportunities); relationships (in particular, the importance of friendships), and perceptions including the existing realities of life for those with intellectual disabilities. The findings advance previous work highlighting the link between living a more authentic life and how education transforms how people with intellectual disabilities view themselves.

AB - Background Older people are at greater risk of both physical impairments and cognitive decline. Although previous studies have examined whether visual and cognitive impairments are associated, findings have been mixed with cognitive performance only crudely assessed. Nonetheless, it remains possible that this association becomes stronger with age. Accordingly, in the present study, we tested the hypothesis that older people with visual impairments have poorer cognitive performance than healthy controls. To this end, we employed validated tools to assess both visual-related and visual-unrelated cognitive skills. Methods A total of 30 older adults (mean age: M = 63.98 years, 30% females) with poor vision (logMAR value 1.0 or higher) and 30 gender- and age-matched healthy controls with no visual impairments (logMAR value 0.2 or lower) took part in this cross-sectional study. After a careful medical and psychiatric examination, participants underwent thorough cognitive testing for working and long-term memory and attention. Results Cognitive performance did not differ between those with and without visual impairments, though better cognitive performance scores were associated with higher educational level. Conclusions Among older people, visual impairment was unrelated to cognitive performance. Rather, cognitive function was related to level of education. PMID- 30301421 TI - Relationship Between Autism Spectrum Disorder Characteristics and Humor Appreciation in Typically Developing Individuals. AB - Extant research regarding humor appreciation in individuals with autism spectrum disorder has been equivocal. This study aims to clarify the relationship between the severity of autism spectrum disorder characteristics and humor appreciation in typically developing individuals. We hypothesized that the severity of autistic traits would have a U-shaped linear relationship with humor appreciation. Eighty typically developing undergraduates between the ages of 18 and 22 years ( Mage = 20.20; SDage = 1.08) were recruited for this study. They were asked to answer 24 statements, devised to measure humor appreciation, in response to a joke stimulus comprising 12 typically funny daily life occurrences (two statements per episode). The participants also responded to the Japanese version of the Autism-Spectrum Quotient. A significant U-shaped relationship was observed between the severity of autistic traits and appreciation of humor. A similar significant U-shaped relationship was seen between humor appreciation and the Autism-Spectrum Quotient subscales of attention switching, communication, and imagination. Humor appreciation showed no significant U-shaped relationship with the Autism-Spectrum Quotient subscales of social skills and local details. This study identified ways that autistic traits may influence how people appreciate humor. These findings are discussed in relation to cognitive processes underlying humor appreciation. PMID- 30301422 TI - The role of social embeddedness for remaining in non-desired workplaces and mental health consequences: Results from Scania Public Health Cohort. AB - AIMS: The aim of the study was to investigate the role of social embeddedness on and off the job in relation to remaining in non-desired workplaces (NDWs) and the development of mental health. METHOD: The study used questionnaire data from the Scania Public Health cohort ( N=2410) that were collected in 2000 (T1), 2005 (T2) and 2010 (T3). Logistic regression models were calculated to probe how NDWs and social embeddedness factors measured at baseline (T1) related to NDWs five years later (T2), and to investigate how NDWs and social embeddedness factors at T2 related to poor mental health at T3. Synergy indices were calculated in both analyses to test for additive v. interactive effects between NDWs and social embeddedness factors on the outcomes. RESULTS: NDWs at baseline and low social embeddedness on and off the job was associated with NDWs at T2. For those in a desired workplace, low support from co-workers as well as low workplace affinity increased the risk to be in an NDW at T2. NDWs and low social embeddedness also associated with impaired mental health (T3). For those in an NDW, low support from co-workers as well as low workplace affinity increased the risk of poor mental health at T3. CONCLUSIONS: This study underlines the importance of social embeddedness for NDWs and the development of poor mental health over time. Particularly low social support from co-workers and low workplace affinity seem to be risk factors for future experience of an NDW and impaired mental health. PMID- 30301423 TI - Investigation of activation mechanism and conformational stability of N-(4-chloro 3-trifluoromethyl-phenyl)-2-ethoxybenzamide and N-(4-chloro-3-trifluoromethyl phenyl)-2-ethoxy-6-pentadecyl-benzamidein the active site of p300 histone acetyl transferase enzyme by molecular dynamics and binding free-energy studies. AB - The CBP (CREB binding protein) and p300 are related to transcriptional coactivator family and are involves several post translational modifications; in which the acetylation is an important factor because it commences the transcription process. Experimental studies report that CTPB [N-(4-chloro-3 trifluoromethyl-phenyl)-2-ethoxy-6-pentadecyl-benzamide] and CTB [N-(4-chloro-3 trifluoromethyl-phenyl)-2-ethoxybenzamide] are good activators of p300 HAT enzyme, but yet the molecular mechanism of their activation is not explored. The present study pertains to determine the intermolecular interactions, stability and binding free energy of CTB and CTPB from the molecular docking, molecular dynamics (MD) simulation and binding free energy calculation. The docking studies of the molecules reveal that the docking score of CTPB (-15.64 kcal/mol) is higher than CTB (-12.30 kcal/mol); contrary, CTB forms strong interaction with the key residues of catalytic site (Tyr1467, Trp1436) compare with CTPB. The MD simulation shows the stability of both molecules in the active site of p300 and their interactions. Furthermore, both docking and MD simulation studies of CTB confirm that it forms expected key interactions and retain the interactions with the active site amino acid residues of p300 on compared with CTPB. For this reason, the CTB recruits more acetyl-CoA in the active site of p300 compared with CTPB; it leads to activate the acetylation process, hence, CTB may be a best activator than CTPB. The binding free energy value of CTPB (-24.79+/-2.38 kcal/mol) is high on compare with CTB (-12.14+/-1.30 kcal/mol) molecule; perhaps the interaction of pentadecyl chain of CTPB with p300, whereas in CTB such group is absent. PMID- 30301424 TI - The Rationality of (Over)imitation. AB - Imitation is a powerful and ubiquitous social learning strategy, fundamental for the development of individual skills and cultural traditions. Recent research on the cognitive foundations and development of imitation, though, presents a surprising picture: Although even infants imitate in selective, efficient, and rational ways, children and adults engage in overimitation. Rather than imitating selectively and efficiently, they sometimes faithfully reproduce causally irrelevant actions as much as relevant ones. In this article, we suggest a new perspective on this phenomenon by integrating established findings on children's more general capacities for rational action parsing with newer findings on overimitation. We suggest that overimitation is a consequence of children's growing capacities to understand causal and social constraints in relation to goals and that it rests on the human capacity to represent observed actions simultaneously on different levels of goal hierarchies. PMID- 30301425 TI - Workplace inclusion of employees with back pain and mental health problems: A focus group study about employees' experiences. AB - AIM: To explore how employees experience workplace inclusion of their colleagues or themselves when having back pain or mental health problems. METHODS: Three focus group interviews with a sample of 16 kindergarten employees were conducted. Systematic Text Condensation was used for analysis. RESULTS: The participants emphasized that it was easier to include colleagues whose health problems were specific, especially when they were open about having problems and expressed their needs for accommodation clearly. Discussions revealed difficulties of acceptance and accommodating colleagues with longstanding health problems, when the burden on the other staff members was heavy, and if it had negative consequences for the kindergarten children. Some of the participants had experienced health problems themselves, which was also described as challenging. Having health problems at work often induced feelings of guilt, being a burden to their colleagues, and experiencing a disparity between the ideals and the realities of inclusion practices. CONCLUSIONS: Workplace inclusion of employees is difficult when their health problems are unspecific, longstanding, and lead to negative consequences for children or colleagues. System level efforts are necessary to reduce negative stereotypes about employees with health problems and facilitate inclusion practices. PMID- 30301426 TI - Discomfort discussing HIV/AIDS and lack of awareness are barriers to partner-to partner pre-exposure prophylaxis education. AB - We suggest that people living with HIV (PLWH) may serve as pre-exposure prophylaxis (PrEP) educators for partners when informed about PrEP. Participants in this study were a convenience sample of PLWH at a public hospital in Miami. A cross-sectional survey assessed the frequency of serostatus disclosure, PrEP awareness, and willingness to recommend PrEP to intimate partners. To evaluate stigma surrounding human immunodeficiency virus (HIV), comfort discussing HIV with family, friends and intimate partners was interrogated. Surveys were completed by 137 participants; 39.5% had potentially sero-discordant sexual partners. Among respondents, 29.2% reported that they 'occasionally' or 'never' disclose HIV status to sexual partners. In all, 66.4% of patients reported that they had never heard of PrEP. After being educated about PrEP, 86.0% of respondents reported that they would encourage partners to use it. Participants were asked how often the subject of HIV comes up in conversations. Most indicated that 'rarely' or 'never' does it come up with friends and family; 46.1% indicated that 'never' or 'rarely' does it come up with partners. In bivariate analyses, participants with prior awareness of PrEP were more likely to indicate higher frequency of conversations regarding HIV with intimate partners. It is concluded that interventions which utilize partner education to increase PrEP uptake should address stigma and knowledge among other barriers. PMID- 30301427 TI - Blunted serum 25(OH)D response to vitamin D3 supplementation in children with autism. AB - INTRODUCTION: Data suggest a potential role for vitamin D in autism spectrum disorder (ASD) prevention and treatment. It is likely that the serum response to vitamin D supplementation contributes to its effectiveness. Multiple factors affect serum vitamin D 25(OH)D response to supplementation. METHODS: We conducted post-hoc analysis of two double-blind, randomized, placebo-controlled trials (RCT) of vitamin D3 supplementation, one RCT involving children with ASD and another involving children with asthma. Both trials were conducted in the same geographic location (Dublin, Ireland, 53 degrees N), conducted over Winter season and utilized the same vitamin D3 dose (2000 IU/day). RESULTS: We included 18 children with ASD and 17 children with asthma. There was no significant difference in 25(OH)D or age at baseline, however, BMI was significantly lower in ASD (P = 0.03). Compliance with vitamin D supplementation was high in both trials. Despite a significantly longer intervention period (20w vs. 15w; P < 0.0001), ASD children had a significantly lower absolute increase (+26 vs. +45 nmol/l) in 25(OH)D (P = 0.04). CONCLUSIONS: Despite similar demographics, children with ASD had a lower increase in 25(OH)D levels with supplementation. Potential mechanisms include altered absorption/metabolism as well as well genetic factors. Clinical and research work relating to vitamin D is ASD should measure 25(OHO)D response to supplementation to assess therapeutic doses. PMID- 30301428 TI - On the Margins of Death: A Scoping Review on Palliative Care and Schizophrenia. AB - Schizophrenia is a serious chronic mental illness that results in marginalization and stigma for sufferers. It is the seventh leading cause for disability worldwide. The symptoms of the illness, including hallucinations, delusions, and extremely disordered thinking and behavior, may also introduce barriers to accessing treatment, education, housing, and employment. Little is known about end-of-life care for individuals with schizophrenia. To address this gap, a scoping review was conducted to enhance understanding of hospice and palliative care for patients with schizophrenia. From this scoping review, 342 unique titles and abstracts were identified through a search of 20 databases, including 11 social science databases, 6 medical databases, and 3 gray literature databases. A total of 32 articles met the inclusion criteria and the following 4 themes were identified: Stigma affecting quality of care and access to care; Issues related to consent and capacity for the patient's end-of-life care decisions and to appoint substitute decision makers; Best practices for psychosocial interventions, pharmacology, family and health-care collaborations, goals of care, setting, and smoking; and Barriers to care, including setting, communication, provider education, and access to care. The review suggests the importance of mandatory interdisciplinary training practices and policy standards outlining cooperative communication across health-care providers. It highlights gaps in evidence-based research on psychosocial interventions and collaborative frameworks to enable the provision of quality end-of-life care for individuals with schizophrenia. PMID- 30301429 TI - Utilizing bioaugmentation to improve performance of a two-phase AnMBR treating sewage sludge. AB - Bioaugmentation in the acid-phase of a two-phase anaerobic membrane bioreactor (AnMBR) treating primary sludge was investigated as a means for targeting and improving hydrolysis and acetogenesis. Bioaugmentation was carried out using a proprietary bioculture blend containing a mixture of hydrolytic, acidogenic, and acetogenic microorganisms. This mixture was added on its own and in combination with recycled anaerobic sludge from the methane-phase of the AnMBR. Both bioaugmentation strategies had a positive effect on overall hydrolysis (25-38%), and acid-phase acetic acid generation (31-52%) compared to operation without bioaugmentation. This led to subsequent increases in average methane production (10-13%), and greater average solids reduction (25-55%). Microbial community analysis using 16S Illumina MiSeq generated sequences revealed increased relative abundance of Acetobacter and Syntrophomonas species in bioaugmented communities, suggesting these to be key players in improvements in process performance. However, in general the relative abundance of bioaugmented microorganisms within bioaugmented communities was relatively low, highlighting the need to optimize the bioculture composition and dosage. Overall, bioaugmentation was found to benefit the conversion of primary sludge to methane, when initial solubility was relatively low. Future work should optimize the bioculture composition and dosing strategy to improve its effectiveness and long-term stability, and minimize associated operating costs. PMID- 30301430 TI - Acute Stroke Treatment by Surgical Recanalization of Extracranial Internal Carotid Artery Occlusion: A Single Center Experience. AB - Ischemic stroke due to an acute occlusion of the extracranial internal carotid artery (eICA) is associated with high morbidity and mortality. The best treatment option remains unclear. This study aims to increase the available therapeutic experience documented for surgical recanalization of acute eICA occlusions. We retrospectively reviewed all hospital records of the University Hospital Jena between 2006 and 2018 to identified patients with acute ischemic stroke due to an occlusion of the eICA who underwent emergent surgical recanalization. We analyzed clinical data, surgical reports, imaging data, and outpatient records. The primary outcome parameter was the modified Rankin Scale (mRS) at 3 months. During the survey, 12 patients (mean age: 62.3 +/- 10.8 years; range: 35-87) underwent emergent surgical recanalization for an acutely symptomatic eICA occlusion. All patients presented with neurological deficits with a mean National Institutes of Health Stroke Scale score at admission of 15.0 +/- 5.1 (range 2-23). Patients were selected for surgery mainly due to the extent of the perfusion mismatch, while stroke severity and age were also considered. The median time from symptom onset to surgery was 309 +/- 122 minutes (range 112-650 minutes). Complete recanalization was obtained in all 12 patients. No patient deteriorated postoperatively, no intracranial hemorrhage was observed, and no patient died in the following 3 months. Favorable outcomes (mRS: 0-2) after 3 months were achieved in 7 of 12 patients. The current study adds support to previous findings that the surgical recanalization of acute eICA occlusions is a possible and safe treatment option. However, a critical patient selection based on mismatch size in perfusion imaging is crucially important for successful treatment. PMID- 30301431 TI - Metal Coordinated Poly-Zinc-Liothyronine Provides Stable Circulating Triiodothyronine Levels in Hypothyroid Rats. AB - BACKGROUND: Liothyronine (LT3) has limited short-term clinical applications, all of which aim at suppressing thyrotropin (TSH) secretion. A more controversial application is chronic administration along with levothyroxine in the treatment of hypothyroidism. Long-term treatment with LT3 is complicated by its unique pharmacokinetics that result in a substantial triiodothyronine (T3) peak in the blood three to four hours after oral dosing. This is a significant problem, given that T3 levels in the blood are normally stable, varying by <10% throughout the day. METHODS: A metal coordinated form of LT3 (Zn[T3][H2O])n, known as poly-zinc liothyronine (PZL), was synthesized and loaded into coated gelatin capsules for delivery to the duodenum where sustained release of T3 from PZL occurs. Male Wistar rats were made hypothyroid by feeding on a low iodine diet and water containing 0.05% methimazole for five to six weeks. Rats were given a capsule containing 24 MUg/kg PZL or equimolar amounts of LT3. Blood samples were obtained multiple times from the tail vein during the first 16 hours, and processed for T3 and TSH serum levels. Some animals were treated daily for eight days, and blood samples were collected daily. RESULTS: Rats given LT3 exhibited the expected serum T3 peak (about fivefold baseline) at 3.5 hours, followed by a rapid decline, with serum levels almost returning to baseline values by 16 hours. In contrast, serum T3 in PZL-treated rats exhibited about a 30% lower T3 peak at nine hours. Furthermore, the plateau time, that is, the time-span during which the serum T3 concentration is at least half of T3 peak, increased from 4.9 to 7.7 hours in LT3- versus PZL-treated rats, respectively. Serum TSH dropped in both groups, but PZL-treated rats exhibited a more gradual decrease, which was delayed by about four hours compared to LT3-treated rats. Chronic treatment with either LT3 or PZL restored growth, lowered serum cholesterol, and stimulated hepatic expression of the Dio1 mRNA and other T3-dependent markers in the central nervous system. CONCLUSION: Capsules of PZL given orally restore T3-dependent biological effects while exhibiting a reduced and delayed serum T3 peak after dosing, thus providing a longer period of relatively stable serum T3 levels compared to capsules of LT3.

AB - The current study used social network analysis (SNA) to examine relationships within three effective Sexual Assault Response Teams (SARTs) that coordinate the response of legal, medical, and advocacy organizations to sexual assault. Within each SART, organizations reported on each other member organization valuing their role, serving as a resource to their work, and communication outside of official meetings. Across the SARTs, there was high connectedness and reciprocity and low to moderate dependence on one organization to drive relationships. However, there was dependence on a subgroup of organizations to drive additional communication relationships. Implications for managing relationships in SARTs are discussed.

AB - PURPOSE: To report on the endovascular management of a patient affected by concomitant left common iliac artery and right superficial femoral artery (SFA) pseudoaneurysms after stent positioning. CASE REPORT: A 77-year-old man affected by severe lower limb atherosclerosis was previously treated with iliac and femoropopliteal Supera stenting procedures; he presented to our emergency department because of bilateral severe claudication recurrence, back pain, and right groin region swelling. Angio-computed tomography (CT) depicted 2 pseudoaneurysms of the left common iliac artery and right SFA, due to stent fracture and stent intussusception, respectively. A 2-step endovascular treatment was planned using bilaterally covered stent-grafts to exclude vascular lesions from blood flow. The devices were successfully deployed without any complication. At 1 month, angio-CT confirmed patency of the implanted stent-grafts showing complete pseudoaneurysm exclusion without leaks. CONCLUSION: Endovascular approach can be a valid option in the treatment of pseudoaneurysms due to stenting procedure complications. PMID- 30301435 TI - Corrigendum. PMID- 30301437 TI - Socioeconomic inequalities in health during the Great Recession: A scoping review of the research literature. AB - AIMS: The so-called 'Great Recession' in Europe triggered widespread concerns about population health, as reflected by an upsurge in empirical research on the health impacts of the economic crisis. A growing body of empirical studies has also been devoted to socioeconomic inequalities in health during the Great Recession. The aim of the current study is to summarise this health inequality literature by means of a scoping review. METHODS: We have performed a scoping review of the research literature (English language) published in the years 2012 2017. Only empirical papers with (a) health status measured on the individual level, (b) information on socioeconomic position (i.e. employment status, educational level, income/wealth, and/or occupational class), and (c) data from European countries in both pre- and post-crisis years were considered relevant. In total, 49 empirical studies fulfilled these inclusion criteria. RESULTS: The empirical findings in the 49 included studies predominantly show that socioeconomic inequalities in health either increased or remained stable from pre to post-crisis years. Two-thirds (65%) of the studies found evidence of either increasing or partially increasing health inequalities. Thus, people in lower socioeconomic strata fared worse overall in terms of health during the Great Recession, compared to people with higher socioeconomic status. CONCLUSIONS: The Great Recession in Europe tends to be followed by increasing socioeconomic inequalities in health. Policymakers should take note of this finding. Widening socioeconomic inequalities in health is a major cause of concern, in particular if health deterioration among 'vulnerable groups' is caused by accelerating cumulative disadvantages. PMID- 30301436 TI - Classical pediatric Hodgkin lymphoma in very young patients: the Italian experience. AB - Many studies have reported a more favorable outcome in younger patients with Hodgkin lymphoma (HL). The aims of this study were to find an appropriate age cutoff able to identify low-risk children and to describe the natural history of 135 very young patients affected by classic HL (cHL). The best age cutoff was identified at 7 years of age. EFS (p = .0451) and PFS (p = .00921) were significantly better in the group of younger patients. The OS rate at 10 years was 97.0% in the younger group and 92.5% in the older one (p = .0448). However, age was not found to be an independent prognostic factor in multivariate analysis and the better prognosis in younger patients seems to be related to more favorable disease characteristics at presentation. PMID- 30301438 TI - Understanding social inequalities in Zika infection and its consequences: A model of pathways and policy entry-points. AB - The health consequences of arbovirus infections such as dengue fever (DENV), Chikungunya (CHIKV) and Zika (ZIKV) has in recent years become a public health challenge, due to failure of prevention followed by increased incidence and pronounced social inequality in occurrence and consequences. This motivates a more systematic analysis of the potential mechanisms and pathways that generate these inequalities. We present in the paper a model that delineates five possible mechanisms driving the inequality of ZIKV and congenital Zika syndrome (CZS). They include differential exposure to bad housing and sanitary conditions, differential exposure to vector density and virus, differential vulnerability to the health effects of exposure to virus, differential intrauterine susceptibility to the teratogenic effects of ZIKV infection and differential social consequences of caring for a disabled child. For each mechanism, we present empirical evidence or need for more research as well as a discussion about policy implications. PMID- 30301439 TI - Urinary B-cell-activating factor of the tumour necrosis factor family (BAFF) in systemic lupus erythematosus. AB - INTRODUCTION: We examined the clinical relevance of urinary concentrations of B cell-activating factor of the tumour necrosis factor family (BAFF) and a proliferation-inducing ligand (APRIL) in systemic lupus erythematosus (SLE). METHODS: We quantified urinary BAFF (uBAFF) by enzyme-linked immunosorbent assay in 85 SLE, 28 primary Sjogren syndrome (pSS), 40 immunoglobulin A nephropathy (IgAN) patients and 36 healthy controls (HCs). Urinary APRIL (uAPRIL) and monocyte chemoattractant protein 1 (uMCP-1) were also quantified. Overall and renal SLE disease activity were assessed using the Systemic Lupus Erythematosus Disease Activity Index 2000. RESULTS: uBAFF was detected in 12% (10/85) of SLE patients, but was undetectable in HCs, IgAN and pSS patients. uBAFF was detectable in 28% (5/18) of SLE patients with active nephritis vs 5/67 (7%) of those without ( p = 0.03), and uBAFF was significantly higher in active renal patients ( p = 0.02) and more likely to be detected in patients with persistently active renal disease. In comparison, uAPRIL and uMCP-1 were detected in 32% (25/77) and 46% (22/48) of SLE patients, respectively. While no difference in proportion of samples with detectable uAPRIL was observed between SLE, HCs and IgAN patients, both uAPRIL and uMCP-1 were significantly detectable in higher proportions of patients with active renal disease. CONCLUSIONS: uBAFF was detectable in a small but a significant proportion of SLE patients but not in other groups tested, and was higher in SLE patients with active renal disease. PMID- 30301440 TI - GATA3 rs3824662 gene polymorphism as possible risk factor for systemic lupus erythematosus. AB - BACKGROUND: There is no report about the association between GATA3 rs3824662 polymorphism and systemic lupus erythematosus (SLE). OBJECTIVE: To investigate the possible role of GATA3 rs3824662 polymorphism as a susceptibility risk factor for either adult SLE (aSLE) or pediatric SLE (pSLE) and to evaluate its role in the development of lupus nephritis (LN) in pSLE. METHODS: Typing of GATA3 rs3824662 polymorphism was done using real-time polymerase chain reaction for three groups; 104 pSLE patients, 140 aSLE patients and 436 age- and sex-matched healthy controls. RESULTS: Non-significant differences were found between SLE patients and healthy controls for the allele and genotype frequencies of GATA3 rs3824662 ( p > 0.05). In pSLE; the AC genotype was associated with LN ( p = 0.04); the A allele and AC genotype were associated with persistent proteinuria ( p = 0.036 and 0.01, respectively) and both the A allele and AA genotype were associated with higher chronicity index ( p = 0.031 and 0.04, respectively). In aSLE; the C allele was associated with cellular cast ( p = 0.03) and thrombocytopenia ( p = 0.01). Logistic regression analysis revealed significant association between the AC+AA genotypes and the prediction of LN and renal active disease in pSLE ( p = 0.04 and 0.01, respectively). CONCLUSION: GATA3 rs3824662 is not associated with susceptibility to SLE either in adult or in pediatric patients; however, in pSLE patients, the heterozygous AC genotype could be considered a risk factor for LN. At the same time, the AC and AA genotypes could be considered as predictors for LN and active renal disease. However, the small sample size is a limiting factor of the present study when interpreting the positive association. PMID- 30301441 TI - Succinate Dehydrogenase-Deficient Gastrointestinal Stromal Tumor With SDHC Germline Mutation and Bilateral Renal and Neck Cysts. AB - Gastrointestinal stromal tumors (GISTs) are rare in children. Succinate dehydrogenase (SDH)-deficient GISTs are wild type and lack KIT proto-oncogene receptor tyrosine kinase and platelet-derived growth factor receptor A ( KIT or PDGFRA) mutations. These tumors result from germline SDH mutations, somatic SDH mutations, or SDH epimutants. Germline mutations in SDH genes ( SDHA, SDHB, SDHC, or SDHD) suggest Carney-Stratakis syndrome, a paraganglioma syndrome with predisposition for GIST. Negative immunohistochemistry for SDHB indicates dysfunction of the mitochondrial complex regardless of the subunit affected. We present an adolescent male with an SDH-deficient GIST and SDHC germline mutation who developed bilateral renal cysts and neck cysts, not previously described in children with this mutation. Germline testing is critical when SDH mutations are discovered due to treatment and surveillance implications. Further investigations are necessary to fully define the phenotypic expression of this mutation. PMID- 30301442 TI - Histological Features of Shallow Placental Implantation Unify Early-Onset and Late-Onset Preeclampsia. AB - Preeclampsia is distinguishable from other hypertensive conditions of pregnancy by its high rates of decidual arteriopathy, the uterine type of chronic hypoxic placental injury, the occurrence of villous infarctions, and clusters of multinucleate trophoblasts in the maternal floor. To retrospectively study the clinical and placental phenotypes of 230 women with early-onset preeclampsia, 261 women with late-onset preeclampsia, and 5059 women without hypertension in pregnancy (comparative group), 24 clinical and 46 placental phenotypes were statistically compared (analysis of variance, chi2 with Bonferroni correction). The frequency of decidual arteriopathy (both hypertrophic and atherosis), patterns of chronic hypoxic placental injury, villous infarction, membrane laminar necrosis, membrane microscopic chorionic pseudocysts, clusters of maternal floor multinucleated trophoblasts, excessive number of extravillous trophoblasts, and intervillous thrombi was strikingly higher in both late-onset preeclampsia and early-onset preeclampsia than in the comparative group without hypertension in pregnancy. All 3 patterns of chronic hypoxic placental injury were 2- to 3-fold more common in preeclampsia. Although the preuterine pattern was as common in early-onset preeclampsia as it was in late-onset preeclampsia, the postuterine pattern was 2-fold more common in early-onset preeclampsia, and chronic villitis of unknown etiology was more common in late-onset preeclampsia than in the other 2 groups. Features of shallow placental implantation occurred at the same frequency in early-onset preeclampsia as in late-onset preeclampsia, which reflects an underlying common pathological mechanism in both subgroups of preeclampsia, while hypoxic lesions and patterns of placental injury were more common in early-onset preeclampsia than in late-onset preeclampsia, which correlates with more severe clinical outcomes of the former. PMID- 30301443 TI - Correlation of Endoscopic and Histologic Severity Scores in Pediatric Ulcerative Colitis at First Presentation. AB - Detailed histologic scoring systems have been developed for the assessment of disease activity in ulcerative colitis. Literature from adult patients has shown some correlation between endoscopy and histology, and reproducibility of histologic scoring systems has also been supported. The effectiveness of endoscopic appearance at predicting histologic scores in pediatric patients has not been well studied, and none of the histologic scoring systems used in adults have had interobserver reproducibility assessed in pediatric patients. We reviewed endoscopic images and concurrent biopsies using Mayo and Geboes scores from the distal colon and rectum in untreated pediatric patients at the presentation of presumed ulcerative colitis based on clinical and endoscopic findings. Interobserver concordance was calculated by weighted-kappa statistic. The averaged histologic scores were compared to endoscopy scores using Spearman's coefficient. Correlation between endoscopic score and each histologic score was weakly to moderately positive, whereas interobserver agreement for histologic scores was fair to moderate, suggesting that the Geboes scoring system has value in pediatric patients. For each histologic parameter, the average score was lower than the average endoscopic score. Examination of larger pediatric cohorts, treated patients, correlations of clinical outcomes with individual histologic parameters, and alternate scoring systems may contextualize these findings. PMID- 30301444 TI - Variation in Platelet Delta Granules Over Time in Young Women Undergoing Evaluation for Heavy Menstrual Bleeding. AB - Delta-granule platelet storage pool deficiency (delta-PSPD) is a qualitative platelet function defect associated with variable bleeding phenotypes. Platelet electron microscopy (EM) is commonly utilized to evaluate for delta-PSPD, but intrapatient variability in platelet delta-granule numbers by EM is currently unknown. Fifteen young women aged 11 to 17 years presenting to a young women's hematology clinic for the evaluation of heavy menstrual bleeding underwent platelet EM testing at their initial hematology clinic visit and at 1 and 3 months later. Platelet aggregation of platelet-rich plasma by light transmission was also performed on all patients at their initial visit. Eight patients had average delta-granules per platelet consistently >=2. Three patients were found to have average delta-granules per platelet <2 on initial testing, 2 of which reverted to >=2 on subsequent testing. When initial average delta-granules per platelet was >=2, initial repeat testing remained so in 83% (95% confidence interval [CI], 52%-98%) of cases and subsequent repeat testing remained so in 75% (95% CI, 43%-95%) of the cases. Platelet aggregation testing was abnormal in 53% of patients, and there was no apparent correlation between platelet EM findings and platelet aggregation testing. In this small group of young women presenting for the evaluation of bleeding symptoms, we found that almost half of the patients had substantial variability in platelet EM results. Given other identified limitations in platelet EM testing, and the intrapatient variability identified in this study, providers should use caution in utilizing EM in isolation to diagnose delta-PSPD. PMID- 30301445 TI - Increased reliance on a right hemispheric mechanism during idiom processing in adults with dyslexia. AB - Previous studies on adults with dyslexia (DYS) have indicated difficulties in the comprehension of figurative language. Using the divided visual field paradigm, the present study investigated the hemispheric processing of idioms among 22 adults with DYS and 21 regular reader (RR) adults. Participants performed a lexical decision task for a target word related to either a literal or a figurative interpretation of an idiom. The results show that whereas the RR group demonstrated a bilateral pattern of hemispheric processing of idiomatic meanings, the DYS group showed a right hemisphere (RH) advantage. Furthermore, both groups demonstrated the typical RH advantage in processing the literal meanings of idioms. Our findings indicate increased recruitment of the RH in dyslexia, probably due to differences in cerebral language areas or weaker LH semantic processing. PMID- 30301446 TI - Comparing Preventable Hospitalizations Among Veterans With and Without Mental Illnesses Before and After Implementation of PACT. AB - OBJECTIVES:: The authors examined whether the rate of preventable hospitalizations among veterans with mental illness changed after implementation of the Department of Veterans Affairs (VA) primary care medical home-Patient Aligned Care Teams (PACT). METHODS:: A 12-year retrospective cohort analysis was conducted of data from 9,206,017 veterans seen in 942 VA primary care clinics between October 2003 and March 2015. Preventable hospitalizations were those related to ambulatory care-sensitive conditions (ACSCs), identified with ICD-9 codes. Changes in rates of ACSC-related hospitalizations were compared between patients with and without mental illness in two age groups (<65, >=65). Patients with mental illness diagnoses were grouped as follows: depression, posttraumatic stress disorder, anxiety, substance use disorder, and serious mental illness. Interrupted time-series analysis was used to model long-term trends and detect deviations after PACT implementation. RESULTS:: There was an overall increase in mental illness diagnoses across both age groups. Among older veterans (>=65) with any mental illness, the rate (per 1,000 patients) of ACSC-related hospitalizations was five fewer in the post-PACT period, compared with the pre PACT period. Among younger veterans (<65), there was a slight increase in ACSC related hospitalizations in years 3-5 post-PACT if they had any mental illness (.6 per 1,000 patients), depression (.3), anxiety (1.4), or a substance use disorder (.6). CONCLUSIONS:: In this retrospective, observational study examining large systemwide changes in clinical practice, mental illness was more likely to be diagnosed after PACT implementation, compared with before, and results suggested a benefit of PACT implementation among older veterans in terms of a reduction in ACSC-related hospitalizations. PMID- 30301447 TI - Survey of Peer Support Specialists: Professional Activities, Self-Rated Skills, Job Satisfaction, and Financial Well-being. AB - As the certified peer support specialist (CPSS) workforce matures, their roles evolve, leading to gaps in knowledge about their activities. This study aimed to address these gaps through a survey on CPSS activities, self-rated skills, job satisfaction, and financial well-being. The project team recruited a community advisory board of CPSSs to lead survey development. A survey link was e-mailed to all known CPSSs in the state of Michigan (N=1,128), yielding 394 respondents (35% response rate), of whom 319 were included in the analysis. The highest skill self ratings included sharing recovery stories (rated very strong by 80%); the lowest included vocational support (rated very strong by 33%). More than 75% were satisfied with their workplace supportiveness; less than one-half were satisfied with their promotion opportunities. When asked if they could generate adequate funds to address a common financial shock, 115 of 301 respondents (38%) were "certain" they could not, suggesting financial vulnerability. These results support developing career ladder opportunities for CPSSs. PMID- 30301448 TI - Integrating Predictive Modeling Into Mental Health Care: An Example in Suicide Prevention. AB - Recent advances in statistical methods and computing power have improved the ability to predict risks associated with mental illness with more efficiency and accuracy. However, integrating statistical prediction into a clinical setting poses new challenges that need creative solutions. A case example explores the challenges and innovations that emerged at a Department of Veterans Affairs hospital while implementing REACH VET (Recovery Engagement and Coordination for Health-Veterans Enhanced Treatment), a suicide prevention program that is based on a predictive model that identifies veterans at statistical risk for suicide. PMID- 30301449 TI - Sociodemographic Characteristics and Job Satisfaction of Psychiatrists in China: Results From the First Nationwide Survey. AB - OBJECTIVE:: The aim of the study was to establish a comprehensive understanding of the sociodemographic characteristics of psychiatrists in China and their working environment and job satisfaction. METHODS:: As part of a national survey, the authors conducted China's first survey in 32 tertiary psychiatric hospitals, including administration of a structured questionnaire for psychiatrists. Participants also completed the Minnesota Satisfaction Questionnaire (MSQ). RESULTS:: Of 3,363 surveyed psychiatrists, 2,715 (81%) responded, and 2,602 (77%) completed the survey. Among completers, 58% were women, and 83% were ages 30-49. Significant differences were found in actual and expected monthly income between male and female psychiatrists and across various regions. The mean+/-SD MSQ score was 71.6+/-14.3, suggesting moderate job satisfaction. The top three reasons for dissatisfaction were low pay, contentious doctor-patient relationships, and a heavy workload. One-fifth (20%) of participants reported an intention to quit their jobs. MSQ score was significantly associated with younger age, shorter working hours, higher monthly pay, and a smaller gap between expected and actual pay. Being in an administrative position, having medical liability insurance, and not having experienced medical disputes appeared to have a positive impact on job satisfaction. CONCLUSIONS:: Compared with their international counterparts, psychiatrists in China have a low level of the job satisfaction, especially those in West China. Given China's increasing demand for psychiatric services, policy makers in China urgently need to find ways to improve the job satisfaction of working psychiatrists and should consider enhancements in financial compensation, the working environment, and malpractice insurance coverage.

PMID- 30301452 TI - Adherence to the neonatal resuscitation algorithm for preterm infants in a tertiary hospital in Spain. AB - BACKGROUND: There is evidence that delivery room resuscitation of very preterm infants often deviates from internationally recommended guidelines. There were no published data in Spain regarding the quality of neonatal resuscitation. Therefore, we decided to evaluate resuscitation team adherence to neonatal resuscitation guidelines after birth in very preterm infants. METHODS: We conducted an observational study. We video recorded resuscitations of preterm infants < 32 weeks' gestational age and evaluated every step during resuscitation according to a score-sheet specifically designed for this purpose, following Carbine's method, where higher scores indicated that more intense resuscitation maneuvers were required. We divided the score achieved by the total possible points per patient to obtain the percentage of adherence to the algorithm. We also compared resuscitations performed by staff neonatologists to those performed by pediatricians on-call. We compared percentages of adherence to the algorithm with the Chi-square test for large groups and Fisher's exact test for smaller groups. We compared assigned Apgar scores with those given after analyzing the recordings and described them by their median and interquartile range. We measured the interrater agreement between Apgar scores with Cohen's kappa coefficient. Linear and logarithmic regressions were drawn to characterize the pattern of algorithm adherence. Statistical analysis was performed using SPSS V.20. A p-value < 0.05 was considered significant. Our Hospital Ethics Committee approved this project, and we obtained parental written consent beforehand. RESULTS: Sixteen percent of our resuscitations followed the algorithm. The number of mistakes per resuscitation was low. Global adherence to the algorithm was 80.9%. Ventilation and surfactant administration were performed best, whereas preparation and initial steps were done with worse adherence to the algorithm. Intubation required, on average, 2.2 attempts; success on the first attempt happened in 33.3% of cases. Only 12.5% of intubations were achieved within the allotted 30 s. Many errors were attributable to timing. Resuscitations led by pediatricians on-call were performed as correctly as those by staff neonatologists. CONCLUSIONS: Resuscitation often deviates from the internationally recognized algorithm. Perfectly performed resuscitations are infrequent, although global adherence to the algorithm is high. Neonatologists and pediatricians need intubation training. PMID- 30301453 TI - Disability, mental health, sexual orientation and gender identity: understanding health inequity through experience and difference. AB - BACKGROUND: This paper focuses on inequities in health in the context of disability, mental health, sexual orientation and gender identity (The authors' location outside of these identities is acknowledged as a serious limitation in discussing experience as a framework to understand health inequity in the dimensions of disability, mental health, sexual orientation and gender identity). These are dimensions that lead to health inequity primarily through the pathways of stigma and discrimination. The aim here is to distinguish the unique characteristics of these groups and thereby try and articulate a new understanding of health and health equity with identity and difference in the foreground. We aim to bring attention to experience as a crucial parameter to discuss health equity in this context. DISCUSSION: Health inequity can be approached in two ways. One is to look at the lacuna in the current public health discourse in addressing the specific health concerns along the dimensions of disability, mental health, sexual orientation and gender identity. The second approach involves a more organic way of taking on board the concerns of these groups, rather than as after-thoughts; this involves a framework that gives a central role to the lived experience of stigma and discrimination. The dimensions of disability, mental health, sexual orientation and gender identity affect health inequities constitutively, instrumentally through co-morbidities, and through stigma either directly or indirectly. Experience of stigma also forms the basis of identities and the difference between identities, which emerges as an important concept in the articulation of health inequities beyond measurable gaps. Recognition and representation of these differences then form the basis of an inclusive articulation on health. CONCLUSION: The centrality of difference and experience prompts us to problematise the idea of equity that rests on 'avoidable and unfair', 'differentials' and even to argue that such a definition based on differentials, used in a quantitative sense, seriously limits our understanding of health inequity. Health equity will therefore not merely mean 'closing avoidable health gaps,' but mandate an inclusive social arrangement that celebrates difference. PMID- 30301454 TI - Standardization and application of a modified RFLP-PCR methodology for analysis of polymorphisms linked to treatment resistance in Ancylostoma braziliense. AB - BACKGROUND: Single nucleotide polymorphisms (SNPs) in codons 167, 198 and 200 of the beta-tubulin isotype 1 gene are associated with benzimidazoles resistance in many helminths. Codon 167 mutation has never been described in hookworms; however, polymorphisms in codons 198 and 200 have been described for Ancylostoma caninum and Necator americanus. These mutations have never been investigated in Ancylostoma braziliense; therefore, it is not known if they are present in this species and whether they are correlated with treatment resistance. The RFLP-PCR technique has been used to analyze these polymorphisms in some nematodes, but depending on the species, these alterations do not create or eliminate any restriction enzyme cleavage site, making it impossible to use this technique. Here, we describe the standardization and application of a modified RFLP-PCR technique for detecting polymorphisms in individual A. braziliense worms recovered from naturally infected dogs in two Brazilian states. RESULTS: The molecular techniques used were sensitive, specific, and easy to apply. To our knowledge, we report for the first time the presence of a polymorphism at codon 198 of the beta-tubulin gene of A. braziliense (1/81; 95% CI: 0-3.69%). CONCLUSIONS: It is not known whether the presence of the mutation in codon 198 of the beta-tubulin gene of A. braziliense has importance for this parasite. However, based on studies of other helminths, it is possible that this polymorphism is directly related to the resistance to benzimidazoles. This may be a major concern, since this nematode has considerable relevance as a parasite of canids and felids and as one of the agents of cutaneous larva migrans in humans. Standardized methodologies will be useful for screening for polymorphisms in the beta-tubulin gene of canine hookworms in a broader population. The method could also be adapted for the analysis of other SNPs in other nematode species. PMID- 30301455 TI - A health equity research agenda for India: results of a consultative exercise. AB - BACKGROUND: This paper describes the process and outcome of a consultative exercise undertaken to develop a medium-term agenda for the next decade, and to identify a short list of immediate priorities for health equity research in India. This exercise was undertaken over 2014-2017 as part of 'Closing the Gap: Health Equity Research Initiative in India', implemented by the Achutha Menon Centre for Health Science Studies, at the Sree Chitra Tirunal Institute of Medical Sciences and Technology, Trivandrum, in south India. METHODS: We adopted a five-step process for the agenda- and priority-setting exercise. The first step, which lasted for approximately 1 year, consisted of a synthesis of evidence on health inequities in India produced during 2000-2014 and identification of gaps. In the second step, we shared the evidence gaps identified and engaged with diverse stakeholders to develop the research agenda through face-to-face and online consultations. In step three, we consolidated the research agenda and identified continuing gaps. Key informant consultations by phone or email with experts in the areas where gaps were identified constituted the fourth step. In the fifth and final step, we organised an expert group consultation to review the agenda and identify immediate research priorities through a consensus process. Overall, approximately 220 persons participated in the entire process, and consisted of persons from diverse disciplines and sectors. RESULTS: The research agenda and immediate priorities that emerged may be categorised into four themes, namely (1) descriptive research on the extent, nature and time trends in health inequities; (2) explanatory research on the pathways through which health inequities are created, and the political or policy environment that facilitates the process; (3) explanatory research that examines how health systems facilitate or mitigate inequities in healthcare; and (4) intervention research on initiatives that helped to mitigate health inequities, and examines the contributing factors. CONCLUSION: The strength of this research agenda is that it was developed through a broad-based consultation with stakeholders representing diverse disciplines, sectors and constituencies. The use of this agenda will help generate evidence that will facilitate India moving closer to the Sustainable Development Goal of leaving no one behind. PMID- 30301456 TI - Castleman disease of the hyaline vascular variant transforming to POEMS syndrome as endpoint: a case report. AB - BACKGROUND: POEMS syndrome is a rare neoplastic syndrome reflected by plasma cell disorder. It is composed by polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes. It is also reported to associate with Castleman disease. The early identification and treatment are pivotal to reduce the morbidity and mortality. CASE PRESENTATION: Here we report a 66-year-old man with treated Castleman disease developing with sequential presence of endocrinopathy polyneuropathy, skin changes, organomegaly and extravascular volume overload within 18 years, which was finally confirmed as POEMS syndrome by positive monoclonal protein. He was thereafter successfully treated with prednisone and azathioprine as primary therapy and thalidomide as maintenance therapy. CONCLUSION: The diagnosis of POEMS is based on a cluster of disorder involved in varied organs. We report a rare case that triggers the need to consider POEMS syndrome diagnosis for patients carrying Castleman disease and polyneuropathy. PMID- 30301457 TI - Globalisation and neoliberalism as structural drivers of health inequities. AB - In this paper, we draw upon and build on three presentations which were part of the plenary session on 'Structural Drivers of Health Inequities' at the National Conference on Health Inequities in India: Transformative Research for Action, organised by the Achutha Menon Centre for Health Science Studies in Trivandrum, India. The three presentations discussed the influential role played by globalisation and neoliberalism in shaping economic, social and political relationships across developed and developing countries. The paper further argues that the twin process of globalisation and liberalisation have been important drivers of health inequities. The first segment of the paper attempts a broader conceptualisation of neoliberalism beyond the economic realm. Using Stephanie Lee Mudge's conceptualisation (Soc Econ Rev 6:703-3, 2008) we have analysed how the political, bureaucratic and intellectual domains of neoliberalism have intersected and redefined the role of state and commercialised health services leading to inequities. Neoliberal ideas have reconfigured the role and changed the priorities of non-governmental organisations resulting in a fracture within this movement. n the second segment, we focus on the rise of American philanthro capitalism, and how the two major foundations, the Rockefeller Foundation (early twentieth century) and the Bill and Melinda Gates Foundation (twenty-first century), have shaped the ideology of institutions engaged in international health and influenced the global health agenda. We discuss how the activities of philanthro-capitalists have transformed the architecture of health governance through their top-down organisational culture and deficit of structures to ensure accountability. The third and final segment of the paper focuses on how neoliberalism as a political project and cultural movement has forged alliances with conservative politics and religious fundamentalisms, resulting in negative consequences for women and other marginalised groups. These alliances have resulted in the control of women's bodies and contributed to the reversal of hard won rights for health and gender justice in many parts of the world. PMID- 30301458 TI - Syringomyelia-like syndrome in neuromyelitis optica spectrum disorder complicated with Sjogren's syndrome: a case report. AB - BACKGROUND: Besides CSF-flow obstruction, syringomyelia is associated with inflammatory spinal cord lesions. However, syringomyelia-like syndrome concomitant with neuromyelitis optica spectrum disorder (NMOSD) and primary Sjogren's syndrome (pSS) is extremely rare. Here, we would like to report a case of a patient with syringomyelia-like syndrome in NMOSD complicated with Sjogren's Syndrome. CASE PRESENTATION: A 64-old male Han Chinese, presented with three episodes of acute demyelinating processes in the central nervous system within 5 years. Firstly, he presented with ascending left lower extremity weakness and numbness, and initially progressive loss of vision in the right eye before 5 years, and subsequently in the right eye 2 months later. High dose corticosteroid therapy was prescribed for this attack. Second, he suffered from refractory gastrointestinal symptoms. such as nausea, vomiting, abdominal pain and early satiety. After the second episode, he received long-term azathioprine and prednisone treatment in low dosages. Six months before admission, he developed the lower back pain and numbness in lower limbs, and urinary incontinence. This time, he complained of acute onset of right lower limb paralysis, paresthesia and urinary incontinence. MRI of the spine revealed a syringomyelia extending from the C7 to T4 levels with serum positive anti-aquaporin-4 antibodies (AQP4-Ab) (indirect immunofluorescence on AQP4 transfected cells). he was serologically positive for both anti-Sjogren's syndrome-related antigen A and B antibodies and there was reduced salivary flow on scintigraphy. Lip salivary gland (LSG) biopsies were graded (grade four lymphocytic infiltration) according to the Chisholm and Mason classification system and by morphometric analysis. And finally, diagnosed as syringomyelia-like syndrome in NMOSD complicated with Sjogren's syndrome. CONCLUSIONS: Although extremely rare, This index patient highlights that syringomyelia could be associated with underlying NMOSD and pSS, and autoimmune disorders should be considered in the initial differential diagnosis, This is very helpful for the therapeutic implications and evaluating curative effect. PMID- 30301459 TI - Coating the plate with antibiotic cement to treat early infection after fracture fixation with retention of the implants: a technical note. AB - BACKGROUND: Local antibiotic therapy has gained increasing attraction in the prevention and treatment of fracture infection. However, no reports have used local antibiotic therapy in the management of early infection after fracture fixation with retention of implants. METHODS: The present surgical technique report the use of antibiotic impregnated bone cement in the management of early infection after fracture fixation. Initially, the fractures were fixed with plates. The average time from initial procedure to debridement was15 days (range 9 to 25 days). The infections were treated with irrigation, debridement, and retention of the implant. The lateral surface of the plates was coated with antibiotic cement and the bone defect was filled with antibiotic cement spacer after thorough debridement. RESULTS: Ten patients underwent this technique. The mean follow-up was 2.0 years (range 6 months to 4 years). The bone union rate was 100%, and the average time to bone healing was5.5 months.There was recurrence of infection in one patient before bone healing, but the implants were left in place until bone healed, and the infection was eradicated after implant removal. CONCLUSION: Coating the plate with antibiotic cement is a simple technique which may play a role in the management of early infection after fracture fixation. PMID- 30301460 TI - Rising plasminogen activator inhibitor-1 and hypoadiponectinemia characterize the cardiometabolic biomarker profile of women with recent gestational diabetes. AB - BACKGROUND: Gestational diabetes (GDM) and milder gestational impaired glucose tolerance (GIGT) identify women at risk of developing type 2 diabetes and cardiovascular disease later in life. Accordingly, the postpartum years after gestational dysglycemia can provide insight into early events in the natural history of these disorders. We thus sought to prospectively evaluate the relationship between gestational glucose tolerance and emerging cardiometabolic biomarkers [adiponectin, chemerin, retinol-binding protein-4 (RBP-4), C-reactive protein (CRP), plasminogen activator inhibitor-1 (PAI-1)] at both 1- and 3-years postpartum in a cohort reflecting the full spectrum of gestational dysglycemia (from normal to GIGT to GDM). METHODS: Three-hundred-and-thirty-nine women completed a glucose challenge test (GCT) and oral glucose tolerance test (OGTT) in pregnancy, which identified 4 gestational glucose tolerance groups: GDM (n = 105); GIGT (n = 59); abnormal GCT with normal OGTT (n = 99); and normal GCT with normal OGTT (n = 76). At 1- and 3-years postpartum, the women underwent repeat OGTT with measurement of biomarkers (adiponectin/chemerin/RBP-4/CRP/PAI-1). RESULTS: Serum adiponectin was lower in women with GDM and GIGT at both 1-year and 3-years (both P <= 0.002), whereas chemerin, RBP-4, CRP and PAI-1 showed no differences across the 4 groups. Importantly, the change in PAI-1 between 1- and 3-years progressively increased from the normal GCT group to the abnormal GCT group to GIGT to GDM (P = 0.03). Indeed, both GDM (t = 2.98, P = 0.003) and GIGT (t = 2.14, P = 0.03) independently predicted an increase in PAI-1 from 1- to 3 years postpartum. CONCLUSIONS: Hypoadiponectinemia and rising PAI-1 over time are early features of the cardiometabolic biomarker profile of women with recent gestational dysglycemia. PMID- 30301461 TI - A resonance Rayleigh scattering sensor for sensitive differentiation of telomere DNA length and monitoring special motifs (G-quadruplex and i-motif) based on the Ag nanoclusters and NAND logic gate responding to chemical input signals. AB - BACKGROUND: Differentiation of telomere length is of vital importance because telomere length is closely related with several deadly diseases such as cancer. Additionally, G-quadruplex and i-motif formation in telomeric DNA have been shown to act as a negative regulator of telomere elongation by telomerase in vivo and are considered as an attractive drug target for cancer chemotherapy. RESULTS: In this assay, Ag nanoclusters templated by hyperbranched polyethyleneimine (PEI-Ag NCs) are designed as a new novel resonance Rayleigh scattering (RRS) probe for sensitive differentiation of telomere length and monitoring special motifs (G quadruplex and i-motif). In this assay, free PEI-Ag NC probe or DNA sequence alone emits low intensities of RRS, while the formation of PEI-Ag NCs/DNA complexes yields greatly enhanced RRS signals; however, when PEI-Ag NCs react with G-quadruplex or i-motif, the intensities of RRS exhibit slight changes. At the same concentration, the enhancement of RRS signal is directly proportional to the length of telomere, and the sensitivity of 64 bases is the highest with the linear range of 0.3-50 nM (limit of detection 0.12 nM). On the other hand, due to the conversion of telomere DNA molecules among multiple surrounding conditions, a DNA logic gate is developed on the basis of two chemical input signals (K+ and H+) and a change in RRS intensity as the output signal. CONCLUSION: Our results indicate that PEI-Ag NCs can serve as a novel RRS probe to identify DNA length and monitor G-quadruplex/i-motif through the different increasing degrees of RRS intensity. Meanwhile, the novel attributes of the nanoprobe stand superior to those involving dyes or labeled DNA because of no chemical modification, low cost, green, and high efficiency. PMID- 30301462 TI - Re-infection rates and clinical outcomes following arthrodesis with intramedullary nail and external fixator for infected knee prosthesis: a systematic review and meta-analysis. AB - BACKGROUND: Knee arthrodesis with intramedullary (IM) nail or external fixator (EF) is the most reliable therapeutic option to achieve definitive infection control in patients with septic failure of total knee arthroplasty (TKA). The first aim of this study was to compare re-infection rates following knee arthrodesis for periprosthetic joint infection (PJI) with IM nail or EF. The second aim was to compare rates of radiographic union, complication, and re operation as well as clinical outcomes. METHODS: A systematic search was performed in electronic databases for longitudinal studies of PJIs (minimum ten patients; minimum follow-up = 1 year) treated by knee arthrodesis with IM nail or EF. Studies were also required to report the rate of re-infection as an outcome measure. Eligible studies were meta-analyzed using random-effect models. RESULTS: The rate (95% confidence intervals) of re-infection was 10.6% (95% CI 7.3 to 14.0) in IM nail arthrodesis studies. The corresponding re-infection rate for EF was 5.4% (95% CI 1.7 to 9.1). This difference was significant (p = 0.009). The use of IM nail resulted in more advantages than EF for frequency of major complications and limb shortening. Other postoperative clinical and radiographic outcomes were similar for both surgical strategies. CONCLUSIONS: The available evidence from the aggregate published data suggests that knee arthrodesis with EF in the specific context of PJI has a reduced risk of re-infection in comparison with the IM nail strategy. The use of IM nail is more effective for the complication rate and shortening of the affected limb. PMID- 30301463 TI - Isolation of anticancer constituents from Cucumis prophetarum var. prophetarum through bioassay-guided fractionation. AB - BACKGROUND: Cucumis prophetarum var. prophetarum is used in Saudi folk medicine for treating liver disorders and grows widely between Abha and Khamis Mushait City, Saudi Arabia. METHODS: Bioassay-guided fractionation and purification were used to isolate the main active constituents of Cucumis prophetarum var. prophetarum fruits. These compounds were structurally elucidated using NMR spectroscopy, mass spectral analyses and x-ray crystallography. All fractions, sub-fractions and pure compounds were screened for their anticancer activity against six cancer cell lines. RESULTS: The greatest cytotoxic activity was found to be in the ethyl acetate fraction, resulting in the isolation of five cucurbitacin compounds [E, B, D, F-25 acetate and Hexanorcucurbitacin D]. Among the cucurbitacins that were isolated and tested cucurbitacin B and E showed potent cytotoxicity activities against all six human cancer cell lines. CONCLUSION: Human breast cancer cell lines were found to be the most sensitive to cucurbitacins. Preliminary structure activity relationship (SAR) for cytotoxic activity of Cucurbitacins against human breast cancer cell line MDA-MB-231 has been reported. PMID- 30301464 TI - Profile of cardiac lipid metabolism in STZ-induced diabetic mice. AB - BACKGROUND: Lipotoxicity contributes to diabetic myocardial disease. In this study, we investigated the lipid species contributing to lipotoxicity and the relationship with peroxisomal beta-oxidation in the heart of diabetic mice. METHODS: Male C57BL/6 mice were randomly divided into a Diabetic group (intraperitoneal injection of STZ) and a Control group (saline). Cardiac function indexes [ejection fraction (EF%) and fractional shortening (FS%)] were evaluated by echocardiography. Morphological changes in the myocardial tissues and mitochondria were assessed by electron microscopy following hematoxylin and eosin staining. Blood myocardial injury indexes and lipids were measured using an automatic biochemical analyzer. Cardiac ATP levels were analyzed using a commercially available kit. mRNA levels of glucose transporter 4 (GLUT4), fatty acid binding protein 3 (FABP3), palmitoyl transferase 1alpha (CPT-1alpha), acyl CoA oxidase 1 (AOX1), D-bifunctional protein (DBP), 3-ketoacyl-CoA thiolase A (THLA), uncoupling protein (UCP) 2 and UCP3 were investigated by quantitative reverse-transcription polymerase chain reaction. FABP3 protein expression was analyzed by Western blotting. Non-targeted metabolomics by LC-MS/MS was applied to evaluate profile of lipid metabolism in heart. RESULTS: Compared with controls, EF% and FS% were significantly reduced in diabetic mice. Furthermore, blood myocardial injury indexes and lipids, as well as myocardial mitochondrial cristae fusion were significantly increased. In the diabetic heart, GLUT4 expression was decreased, while expression of FABP3, CPT-1alpha, AOX1, DBP, THLA, UCP2 and UCP3 was increased, and ATP levels were reduced. In total, 113 lipids exhibited significant differential expression (FC > 2, P < 0.05) between the two groups, with sphingolipid metabolism identified as the top-ranking affected canonical pathway. In the diabetic heart, long-chain hydroxyl-acylcarnitines (8/8) and acylcarnitines (6/11), triglycerides (2/5), and diacyglycerol (3/7) were upregulated, while very long-chain polyunsaturated fatty acids (PUFAs) (5/6) including eicosapentaenoate, docosahexaenoate, phosphocholine (11/19), lysophosphocholine (5/9), phosphoethanolamine (7/11), lysophosphoethanolamine (7/10), phosphatidylglycerol (6/8), phosphoserine (6/8), phosphatidylinositol (2/2), phosphatidic acid (1/1), lysophosphatidic acid (1/1) and sphingomyelin (6/6) were downregulated. CONCLUSIONS: Our data suggest that the increase in toxic lipid species and decreased in PUFAs undergoing peroxisomal beta-oxidation, combined with the reduction in phospholipids cause mitochondrial injury and subsequent uncoupling of phosphorylation and ATP deficiency; thereby leading to diabetic heart dysfunction. PMID- 30301465 TI - Multidisciplinary approach for treatment of a dentigerous cyst - marsupialization, orthodontic treatment, and implant placement: a case report. AB - BACKGROUND: Dentigerous cysts are common odontogenic cysts associated with unerupted teeth. We describe a previously unreported case of a multidisciplinary approach using surgical, orthodontic, and implant treatment to establish the occlusion for a patient with a maxillary dentigerous cyst. CASE PRESENTATION: An 18-year-old Japanese woman visited our hospital with a chief complaint of gingival swelling in her anterior maxillary region, midline diastema, and tooth crowding. Her main symptom was this gingival swelling. A panoramic radiograph revealed a radiolucent area, 30 mm in diameter, round in shape, and with well demarcated margins including the maxillary canine. Computed tomography revealed a cystic cavity filled with homogeneous fluid of the same density as water, and a distolingually inclined canine. Our clinical diagnosis was maxillary dentigerous cyst with an unerupted distolingually inclined canine. The selected treatment was marsupialization of the dentigerous cyst, followed by orthodontic traction of the unerupted canine, and simultaneous orthodontic treatment of the midline diastema and tooth crowding. The orthodontic traction failed because the canine did not erupt completely, and the canine was extracted. The treatment plan was then changed to implant treatment after the tooth crowding and midline diastema had been improved. Because the alveolar ridge width was inadequate, the implant was placed after a two-stage implant treatment; therefore, a satisfactory occlusion could be achieved. Our patient did not experience any complications, and the cyst has not recurred. A radiograph taken 7 years after marsupialization of the dentigerous cyst revealed that the cystic cavity had been replaced by new bone. CONCLUSIONS: In general, orthodontic traction of an unerupted tooth after marsupialization should be the best option. However, if orthodontic traction fails, a multidisciplinary approach involving implant treatment may be necessary. We describe a case in which a multidisciplinary approach involving surgical, orthodontic, and implant treatment was used to establish a satisfactory occlusion for a patient with a dentigerous cyst. PMID- 30301466 TI - Neurophysiological signals as predictive translational biomarkers for Alzheimer's disease treatment: effects of donepezil on neuronal network oscillations in TgF344-AD rats. AB - BACKGROUND: Translational research in Alzheimer's disease (AD) pathology provides evidence that accumulation of amyloid-beta and hyperphosphorylated tau, neuropathological hallmarks of AD, is associated with complex disturbances in synaptic and neuronal function leading to oscillatory abnormalities in the neuronal networks that support memory and cognition. Accordingly, our recent study on transgenic TgF344-AD rats modeling AD showed an age-dependent reduction of stimulation-induced oscillations in the hippocampus, and disrupted long-range connectivity together with enhanced neuronal excitability in the cortex, reflected in greatly increased expression of high-voltage spindles, an epileptic absence seizure-like activity. To better understand the translational value of observed oscillatory abnormalities in these rats, we examine here the effects of donepezil, an acetylcholine esterase inhibitor clinically approved for AD treatment. METHODS: Brainstem nucleus pontis oralis stimulation-induced hippocampal oscillations were recorded under urethane anesthesia in adult (6 month-old) and aged (12-month-old) TgF344-AD and wild-type rats. Spontaneous cortical activity was monitored in a cohort of freely behaving aged rats implanted with frontal and occipital cortical electroencephalography (EEG) electrodes. RESULTS: Subcutaneous administration of donepezil significantly augmented stimulation-induced hippocampal theta oscillation in aged wild-type rats and both adult and aged TgF344-AD rats, which have been previously shown to have diminished response to nucleus pontis oralis stimulation. Moreover, in adult TgF344-AD rats, donepezil also significantly increased theta phase-gamma amplitude coupling in the hippocampus during stimulation. However, neither of these effects were significantly changed in adult wild-type rats. Under freely behaving conditions, donepezil treatment had the opposite effect on cortical oscillatory connectivity in TgF344-AD and wild-type rats, and it reduced the occurrence of high-voltage spindle activity in TgF344-AD rats. CONCLUSIONS: Together, these results imply that pharmacologically enhancing cholinergic tone with donepezil could partially reverse oscillatory abnormalities in TgF344-AD rats, which is in line with its clinical effectiveness in AD patients. Therefore, our study suggests good translational opportunities for these neurophysiological signals recorded in TgF344-AD rats, and their application could be considered in drug discovery efforts for developing therapies with disease-modifying potential. PMID- 30301467 TI - Infant progressive colonic stenosis caused by antibiotic-related Clostridium difficile colitis - a case report and literature review. AB - BACKGROUND: Colonic stenosis is a rare cause of pediatric intestinal obstruction. The root cause underlying colonic stenosis is unclear and there is no fixed operation. CASE PRESENTATION: We reported on a male infant with progressive colonic stenosis caused by antibiotic-related colitis. The infant was admitted to our hospital with pneumonia but developed progressive abdominal distension and diarrhea following antibiotic treatment with meropenem. Initial testing of stool culture showed a Clostridium difficile infection. Additional testing with barium enema imaging showed stenosis at the junction of the sigmoid and descending colon at first and another stenosis occurred at the right half of the transverse colon 3 weeks later. Staged surgical treatment was performed with primary resections of the two parts suffering stenosis, ileostomy, and secondary intestinal anastomosis. A pathological exam then confirmed the diagnosis of colonic stenosis and the patient had an uneventful recovery and has been recovering well as evidenced by the 1-year follow-up. CONCLUSIONS: Based on a review of the literature and our case report, we found that progressive colonic stenosis caused by colitis due to antibiotic-related Clostridium difficile infection is rare in infants. Infants with colitis and repeated abdominal distention, vomiting, and constipation should be treated with the utmost caution and screened. Despite this, clinical manifestations depended on the severity of the stenosis. Barium enema, colonoscopy, laprascopy or laparotomy and colonic biopsy are helpful for diagnosis and differential diagnosis. While both one-stage and multiple-stage operations are feasible, a staged operation should be used for multiple colonic stenoses. PMID- 30301468 TI - Young man with severe metabolic acidosis after transformer oil ingestion: a case report. AB - BACKGROUND: Transformer oil is used in oil-filled transformers for its insulating as well as coolant properties. Transformer oil ingestion for attempted suicide is seldom heard of. Our patient's case presented us with a major diagnostic as well as treatment challenge because we encountered such a case for the first time and were totally unaware of the fact that methanol might make up the main component of an aged transformer oil. CASE PRESENTATION: A 19-year-old Pakistani/Asian man was brought to our hospital with altered sensorium. He was found to have elevated anion gap acidosis, increased osmolal gap, and acute kidney injury. He had no evidence of rhabdomyolysis or hemolysis. Computed tomography of his head showed cerebral edema. He was resuscitated with intravenous fluids and bicarbonate. Three days later, he confessed taking transformer oil with suicidal intention. His clinical picture mimicked acute methanol intoxication. With an initial improvement in his neurological status, he started complaining of constant headache with episodes of agitation and delirium. His renal function continued worsening despite an adequate urine output. He showed a remarkable improvement in his neurological state after just one session of hemodialysis. CONCLUSIONS: There is evidence that aged transformer oil contains methanol, and a patient who consumes it can present with features mimicking acute methanol intoxication. PMID- 30301469 TI - Profiling the airway in the macaque model of tuberculosis reveals variable microbial dysbiosis and alteration of community structure. AB - BACKGROUND: The specific interactions of Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis (TB), and the lung microbiota in infection are entirely unexplored. Studies in cancer and other infectious diseases suggest that there are important exchanges occurring between host and microbiota that influence the immunological landscape. This can result in alterations in immune regulation and inflammation both locally and systemically. To assess whether Mtb infection modifies the lung microbiome, and identify changes in microbial abundance and diversity as a function of pulmonary inflammation, we compared infected and uninfected lung lobe washes collected serially from 26 macaques by bronchoalveolar lavage over the course of infection. RESULTS: We found that Mtb induced an initial increase in lung microbial diversity at 1 month post infection that normalized by 5 months of infection across all macaques. Several core genera showed global shifts from baseline and throughout infection. Moreover, we identified several specific taxa normally associated with the oral microbiome that increased in relative abundance in the lung following Mtb infection, including SR1, Aggregatibacter, Leptotrichia, Prevotella, and Campylobacter. On an individual macaque level, we found significant heterogeneity in both the magnitude and duration of change within the lung microbial community that was unrelated to lung inflammation and lobe involvement as seen by positron emission tomography/computed tomography (PET/CT) imaging. By comparing microbial interaction networks pre- and post-infection using the predictive algorithm SPIEC EASI, we observe that extra connections are gained by Actinomycetales, the order containing Mtb, in spite of an overall reduction in the number of interactions of the whole community post-infection, implicating Mtb-driven ecological reorganization within the lung. CONCLUSIONS: This study is the first to probe the dynamic interplay between Mtb and host microbiota longitudinally and in the macaque lung. Our findings suggest that Mtb can alter the microbial landscape of infected lung lobes and that these interactions induce dysbiosis that can disrupt oral-airway boundaries, shift overall lung diversity, and modulate specific microbial relationships. We also provide evidence that this effect is heterogeneous across different macaques. Overall, however, the changes to the airway microbiota after Mtb infection were surprisingly modest, despite a range of Mtb-induced pulmonary inflammation in this cohort of macaques. PMID- 30301471 TI - The knowledge and attitudes of general practitioners to the assessment and management of pain in people with dementia. AB - BACKGROUND: Pain in people with dementia is underdiagnosed and undertreated. General practitioners (GPs) play a pivotal role in dementia care but their perspectives on pain in people with dementia remains under-researched. The aim of this study was to explore GPs' knowledge and attitudes towards pain assessment and management in people with dementia. METHODS: This was a descriptive cross sectional study. A questionnaire was adapted from a previous study and piloted with 5 GPs. The questionnaire was posted to a census sample of all GPs in Cork city and county in the southern region of Ireland. The questionnaire collected demographic information, responses to a series of Likert-type statements assessing GPs' knowledge and attitudes, and provided an opportunity for the GP to give qualitative feedback on their experiences of managing pain in dementia. SPSS v25 was used for statistical analysis. Qualitative responses were thematically analysed. RESULTS: Of the 320 questionnaires posted, 157 completed questionnaires were returned (response rate of 49%). The sample was representative of GPs nationally in terms of years in GP practice and practice location. Over two thirds (108/157) of respondents had a nursing home commitment. Only 10% of respondents (16/157) were aware of any dementia-specific pain assessment tools. The larger the nursing home commitment of the GP the more likely they were to be familiar with these tools (p = 0.048). The majority of respondents (113/157) believed people with dementia could not self-report pain. Respondents were uncertain about the safety of using opioid medications to treat pain in people with dementia with only 51.6% agreeing that they were safe. The qualitative comments highlighted the importance the GPs placed on surrogate reports of pain, GPs' uncertainty regarding the value of formal pain assessment tools and the challenges caused by under-resourcing in general practice. CONCLUSION: This study has highlighted aspects of pain assessment and management in dementia that GPs find challenging. Guidance on pain assessment and management in people with dementia do not appear to be translating into clinical practice. The findings will inform educational interventions being developed by our research team as part of the implementation of the Irish national dementia strategy. The knowledge and attitudes of general practitioners to the assessment and management of pain in people with dementia. PMID- 30301470 TI - Specific microRNA signatures in exosomes of triple-negative and HER2-positive breast cancer patients undergoing neoadjuvant therapy within the GeparSixto trial. AB - BACKGROUND: The focus of this study is to identify particular microRNA (miRNA) signatures in exosomes derived from plasma of 435 human epidermal growth factor receptor 2 (HER2)-positive and triple-negative (TN) subtypes of breast cancer (BC). METHODS: First, miRNA expression profiles were determined in exosomes derived from the plasma of 15 TNBC patients before neoadjuvant therapy using a quantitative TaqMan real-time PCR-based microRNA array card containing 384 different miRNAs. Forty-five miRNAs associated with different clinical parameters were then selected and mounted on microRNA array cards that served for the quantification of exosomal miRNAs in 435 BC patients before therapy and 20 healthy women. Confocal microscopy, Western blot, and ELISA were used for exosome characterization. RESULTS: Quantification of 45 exosomal miRNAs showed that compared with healthy women, 10 miRNAs in the entire cohort of BC patients, 13 in the subgroup of 211 HER2-positive BC, and 17 in the subgroup of 224 TNBC were significantly deregulated. Plasma levels of 18 exosomal miRNAs differed between HER2-positive and TNBC subtypes, and 9 miRNAs of them also differed from healthy women. Exosomal miRNAs were significantly associated with the clinicopathological and risk factors. In uni- and multivariate models, miR-155 (p = 0.002, p = 0.003, respectively) and miR-301 (p = 0.002, p = 0.001, respectively) best predicted pathological complete response (pCR). CONCLUSION: Our findings show a network of deregulated exosomal miRNAs with specific expression patterns in exosomes of HER2 positive and TNBC patients that are also associated with clinicopathological parameters and pCR within each BC subtype. PMID- 30301472 TI - Investigating the growing trend of non-drinking among young people; analysis of repeated cross-sectional surveys in England 2005-2015. AB - BACKGROUND: Non-drinking among young people has increased over the past decade in England, yet the underlying factor driving this change is unknown. Traditionally non-drinking has been found to be associated with lower socio-economic status and poorer health. This study explores among which sub-groups non-drinking has increased, and how this correlates with changes in drinking patterns, to identify whether behaviours are becoming more polarised, or reduction is widespread among young people. METHODS: Among participants aged 16 to 24 years (N = 9699), within the annual cross-sectional nationally-representative Health Survey for England 2005-2015 datasets, the following analyses were conducted: 1) The proportion of non-drinkers among social-demographic and health sub-groups by year, and tests for linear trends among sub-groups, adjusting for age were calculated. In pooled analyses, an interaction between year and each variable was modelled in sex- and age-adjusted logistic regression models on the odds of being a non-drinker versus drinker 2) At the population level, spearman correlation co-efficients were calculated between the proportion non-drinking and the mean alcohol units consumed and binge drinking on the heaviest drinking day, by year. Ordinary least squares regression analyses were used, modelling the proportion non-drinking as the independent variable, and the mean units/binge drinking as the dependent variable. RESULTS: Rates of non-drinking increased from 18% (95%CI 16-22%) in 2005 to 29% (25-33%) in 2015 (test for trend; p < 0.001), largely attributable to increases in lifetime abstention. Not drinking in the past week increased from 35% (32-39%) to 50% (45-55%) (p < 0.001). Significant linear increases in non drinking were found among most sub-groups including healthier sub-groups (non smokers, those with high physical activity and good mental health), white ethnicity, north and south regions, in full-time education, and employed. No significant increases in non-drinking were found among smokers, ethnic minorities and those with poor mental health. At the population-level, significant negative correlations were found between increases in non-drinking and declines in the mean units consumed (rho = - 0.85, p < 0.001), and binge drinking (rho = - 0.87, p < 0.001). CONCLUSION: Increases in non-drinking among young people has coincided with a delayed initiation into alcohol consumption, and are to be welcomed. Future research should explore attitudes towards drinking among young people. PMID- 30301473 TI - Exercise intervention alters HDL subclass distribution and function in obese women. AB - BACKGROUND: Obesity is associated with a change in high-density lipoprotein (HDL) function and subclass. Exercise training reduces cardiovascular risk in obese patients. We aimed to explore the effect of an exercise training stimulus on HDL functionality and subclass in obese women. METHODS: Thirty-two obese black South African women were randomly assigned to exercise (combined aerobic and resistance exercise) or control (no exercise) conditions for 12-weeks. Pre- and post-testing included venous blood sampling for analysis of lipid profile and HDL functionality, by measuring cellular cholesterol efflux capacity, reduction in endothelial vascular cell adhesion molecule (VCAM) expression (anti-inflammatory function), paraoxonase (PON) (antioxidative function) and platelet activating factor acetylhydrolase (PAF-AH) activities (anti-thrombotic function). PON-1 and PAF-AH expression were determined in serum and in isolated HDL using Western blotting. Levels of large, intermediate and small HDL subclasses were measured using the Lipoprint(r) system. RESULTS: Exercise training resulted in a decrease in body mass index (- 1.0 +/- 0.5% vs + 1.2 +/- 0.6%, p = 0.010), PON activity (- 8.7 +/- 2.4% vs + 1.1 +/- 3.0%, p = 0.021), PAF-AH serum expression (- 22.1 +/- 8.0% vs + 16.9 +/- 9.8, p = 0.002), and the distribution of small HDL subclasses (- 10.1 +/- 5.4% vs + 15.7 +/- 6.6%, p = 0.004) compared to controls. Exercise did not alter HDL cellular cholesterol efflux capacity and anti-inflammatory function. CONCLUSIONS: These results demonstrate the potential for exercise training to modify HDL subclass distribution and HDL function in obese women. TRIAL REGISTRATION: Clinical trials number: PACTR201711002789113 . PMID- 30301475 TI - Endosuture trainer box simulator as a tool for training and teaching in bariatric laparoscopic surgery. AB - BACKGROUND: Video surgery requires acquisition of psychomotor skills that are different from those required for open surgery. The aim of this study was to assess the EndoSuture Trainer Box Simulator (ESTBS), a new bariatric laparoscopic skills simulator, as a tool for surgical education, comparing it with a standard laparoscopic trainer (SLT). METHODS: A randomized prospective crossover study was designed to compare ESTBS versus SLT as a tool for training bariatric laparoscopic skills. Participants were assigned to perform a task simulating Nissen fundoplication operation. All subjects evaluated the simulators concerning to their performance on simulating laparoscopic procedures by the use of a questionnaire comparing: triangulation, resistance and resilience, spatial perception (stereotaxy), ergonomics and positioning, inverted movements, visibility, design, technical and technological resources for training and education. The overall score was defined as the median value obtained. A total of 37 participants were enrolled in the study, including 29 experienced surgeons (78.37%) and 08 surgical residents (21.63%). RESULTS: A superior performance was observed with ESTBS as compared to SLT upon 7 of the 10 items evaluated in the questionnaire. Additionally, the overall score of ESTBS (median of 4, very good) was significantly higher (P < 0.0001) than that of SLT (median of 3, good). For the items, triangulation, resistance and resilience, ergonomics, design, training, technology and teaching, the evaluation for the ESTBS was very good and excellent, which was significantly higher than obtained by SLT. Also, ESTBS was cheaper. CONCLUSIONS: The ESTBS was shown to present excellent technical and technological performances and appears to constitute a useful cost-effective promising instrument for teaching and training bariatric surgical laparoscopic skills. PMID- 30301474 TI - Do medical conditions predispose to the development of chronic back pain? A longitudinal co-twin control study of middle-aged males with 11-year follow-up. AB - BACKGROUND: Poor general health predicts the transition to chronic back pain (CBP), but the role of specific medical conditions in the development of CBP is unclear. The study aim was to examine the association of medical conditions with the development of CBP ("incident CBP"), while controlling for familial factors, including genetics. METHODS: This was a longitudinal co-twin control study conducted in a nationwide United States sample from the Vietnam Era Twin Registry. The study sample included 3045 males without back problems at baseline, including 662 complete twin pairs, who were followed for 11 years. Baseline surveys inquired about self-reported medical conditions (arthritis, diabetes, hypertension, and coronary artery disease [CAD]). A medical comorbidity score was calculated based on the presence and/or treatment of 8 medical conditions. Covariates included age, race, and education. At 11-year follow-up, participants reported ever having had CBP. Odds ratios (ORs) and 95% confidence intervals (CI) were estimated when considering twins as individuals, and in matched-pair co-twin control analyses adjusting for familial/genetic factors. RESULTS: Mean age at baseline was 51 years and 17% of participants developed CBP over the 11-year follow-up. Arthritis was significantly associated with incident CBP in individual level analysis (OR 1.8 [95% CI 1.4-2.2]), but not within-pair analysis (OR 0.9 [95% CI 0.4-1.9]. CAD (OR 1.6 [95% CI 1.0-2.3]), hypertension (OR 1.3 [95% CI 1.0 1.5]), and the medical comorbidity score (OR 1.2 [95%CI 1.1-2.2]) were significantly associated with incident CBP in individual-level analyses; associations in within-pair analyses were of comparable magnitude, but not statistically significant. Diabetes was not associated with incident CBP. CONCLUSIONS: Arthritis, hypertension, CAD, and medical comorbidity score were associated with incident CBP in the current study. However, the association between arthritis and incident CBP was confounded by familial factors. This suggests that prevention or treatment of arthritis is unlikely to be useful for CBP prevention. Our findings cannot exclude the possibility of causal associations between CAD, hypertension, and medical comorbidities and incident CBP. PMID- 30301476 TI - Phylogeny and comprehensive revision of mugiliform-infecting myxobolids (Myxozoa, Myxobolidae), with the morphological and molecular redescription of the cryptic species Myxobolus exiguus. AB - Mullets inhabit a wide range of habitats from tropical to temperate regions and play a critical role in their ecosystems. This commercially important fish group constitutes a significant source of food in several geographic regions, and the production of some species for consumption is an increasing trend. About 64 myxosporean species have been reported in mullets, some of which are cryptic, as is the case of Myxobolus exiguus, and M. muelleri. This paper provides, for the first time, a detailed and critical revision of the data available for myxobolids reported in mullets, determining the species that have bona fide mugiliform fish hosts, in accordance with the original species descriptions, the available molecular data and the currently accepted taxonomic and phylogenetic criteria. Phylogenetic analyses using Bayesian inference and maximum-likelihood methodologies suggest that the evolutionary history of myxobolids with bona fide mugiliform fish hosts reflects that of its vertebrate hosts, while reinforcing known evolutionary factors and old systematic issues of the clade of myxobolids. A comprehensive morphological, ultrastructural and molecular redescription is also provided for the cryptic species M. exiguus, from infections in the visceral peritoneum of the thinlip-grey mullet Chelon ramada in the River Minho, Portugal. PMID- 30301477 TI - Psychological distress and psychiatric disorder after natural disasters: systematic review and meta-analysis. AB - BACKGROUND: Natural disasters are increasing in frequency and severity. They cause widespread hardship and are associated with detrimental effects on mental health.AimsOur aim is to provide the best estimate of the effects of natural disasters on mental health through a systematic review and meta-analysis of the rates of psychological distress and psychiatric disorder after natural disasters. METHOD: This systematic review and meta-analysis is limited to studies that met predetermined quality criteria. We required included studies to make comparisons with pre-disaster or non-disaster exposed controls, and sample representative populations. Key studies were identified through a comprehensive search of PubMed, EMBASE and PsycINFO from 1980 to 3 March 2017. Random effects meta analyses were performed for studies that reported key outcomes with appropriate statistics. RESULTS: Forty-one studies were identified by the literature search, of which 27 contributed to the meta-analyses. Continuous measures of psychological distress were increased after natural disasters (combined standardised mean difference 0.63, 95% CI 0.27-0.98, P = 0.005). Psychiatric disorders were also increased (combined odds ratio 1.84, 95% CI 1.43-2.38, P < 0.001). Rates of post-traumatic stress disorder and depression were significantly increased after disasters. Findings for anxiety and alcohol misuse/dependence were not significant. High rates of heterogeneity suggest that disaster-specific factors and, to a lesser degree, methodological factors contribute to the variance between studies. CONCLUSIONS: Increased rates of psychological distress and psychiatric disorders follow natural disasters. High levels of heterogeneity between studies suggest that disaster variables and post-disaster response have the potential to mitigate adverse effects.Declaration of interestNone. PMID- 30301478 TI - Does adding water to a dry starter diet improve calf performance during winter? AB - Very recently, we added water to a dry texturized starter diet and found substantial improvements in calf performance during summer, leading to the hypothesis that the wet starter diet would also benefit calf performance during winter. Forty-five 3-day-old male Holstein calves (BW 43.4+/-3.4 kg) were blocked by initial BW and distributed randomly to one of three starter diets (1 calf per pen; 15 pens per treatment) that differed only in moisture content as 90%, 75% and 50% dry matter (DM; DM90, DM75 and DM50, respectively). The starter diet comprised 55.1% ground ingredients (soybean meal, barley and corn gluten meal), 21.9% whole corn, 10% rolled barley and 10% chopped alfalfa hay. The mean ambient temperature averaged 2.1+/-0.9 degrees C during the 70-day experiment. Calves were weaned at day 50 of the study. Although starter feed intake remained unaffected by treatment, the calves receiving DM75 and DM50 consumed more starter feed (DM basis) than those receiving DM90 diet during the first 20 days of the experiment. Body weight at weaning exhibited a quadratic response with the heaviest weaning weight (76.8 kg) occurring when calves consumed DM75 diet. Adding water to the dry starter diet tended to linearly increase final BW. Average daily gain during the pre- (0.67 kg/day) and post-weaning (1.22 kg/day) periods was the greatest for calves receiving DM75 and DM50, respectively. Although feed efficiency during the pre-weaning and overall periods did not differ across the treatments, a quadratic effect was detected in the post-weaning feed efficiency, with the lowest value being observed with DM75 diet. No difference was noted on skeletal growth parameters measured on days 50 and 70. Adding water to the dry starter diet linearly increased total volatile fatty acids concentration in the rumen. No difference among treatments existed in calf behavior recorded on days 35 and 70. As moisture content of the starter diet increased, the extent of sorting for long particles (>2 mm) and against fine particles (<0.125 mm) decreased. During the 70-day winter trial, adding water to the dry texturized starter diet with 10% chopped alfalfa hay resulted in a higher feed intake during the first weeks of life, a quadratic tendency toward improved growth rate during the pre-weaning period, and possibly a more functional rumen fermentation. A wet starter diet with 75% DM in the physical form offered in this study can be recommended to improve calf performance during winter. PMID- 30301479 TI - Effects of feeding treatment on growth rates, metabolic profiles and age at puberty, and their relationships in dairy heifers. AB - Puberty attainment in dairy heifers has been widely studied from a hormonal point of view, but few studies have focussed on puberty-blood profile relationships during growth. We led experiments to determine the effects of feeding treatments on growth parameters, age at puberty and plasma biochemical profiles, and the relationships between age at puberty and metabolic profiles at 6, 9, 12 and 15 months (mo) of age. Blood samples were collected from 67 Holstein heifers, born between September 2011 and February 2012, every 10 days from 5.5 mo of age until heifers were considered pubertal (plasma progesterone concentration greater than 1.0 ng/ml) or oestrus synchronisation (November 2012; 11 to 15 mo of age). Heifers born before 30 November were fed either a standard diet (SD, n=27) or an intensive-plane diet (ID1, n=27) from 0 to 6 mo of age. This strategy aimed to reach 190 to 200 kg (SD) or 220 to 230 kg (ID1) BW at 6 mo of age. All heifers born after 1 December received an intensive-plane diet (ID2, n=13) from birth until oestrus synchronisation, in order to reach a similar BW at first insemination as heifers born before 1 December. Only 56 heifers reached puberty before oestrus synchronisation, at an average age of 10.3+/-2.2 mo (6.2 to 14.4 mo) and a BW of 296+/-40 kg (224 to 369 kg). There was no difference among the three feeding treatments until 6 mo, but at 9, 12 and 15 mo of age, ID2 (n=11) heifers weighed 37, 52 and 30 kg more than SD (n=22) and ID1 (n=23) heifers (P<0.001), respectively. Glucose, non-esterified fatty acids, albumin, aspartate aminotransferase, alkaline phosphatase and tartrate-resistant acid phosphatase, calcium, phosphorus, potassium and iron decreased with age, whereas beta hydroxybutyric acid, total cholesterol, creatinine, the creatinine : albumin ratio, alanine aminotransferase and chloride increased. The feeding treatment significantly affected creatinine, the creatinine : albumin ratio, and phosphorus and sodium levels, which were higher for ID2 heifers compared with SD and ID1. A logistic regression based on plasma metabolites at 6 mo of age to explain puberty attainment before or at 12 mo of age showed a positive relationship with plasma cholesterol (odds ratio=9.05). In conclusion, the feeding treatment had minor consequences on plasma metabolites, but it did affect growth performance. PMID- 30301481 TI - Population genetic structure and putative migration pathway of Sogatella furcifera (Horvath) (Hemiptera, Delphacidae) in Asia. AB - The white-backed planthopper, Sogatella furcifera (Horvath) (Hemiptera, Delphacidae), has emerged as a serious rice pest in Asia. In the present study, 12 microsatellite markers were employed to investigate the genetic structure, diversity and migration route of 43 populations sampled from seven Asian countries (Bangladesh, China, Korea, Laos, Nepal, Thailand, and Vietnam). According to the isolation by distance analysis, a significant positive correlation was observed between genetic and geographic distances by the Mantel test (r2 = 0.4585, P = 0.01), indicating the role of geographic isolation in the genetic structure of S. furcifera. A population assignment test using the first generation migrants detection method (thresholds a = 0.01) revealed southern China and northern Vietnam as the main sources of S. furcifera in Korea. Nepal and Bangladesh might be additional potential sources via interconnection with Vietnam populations. This paper provides useful data for the migration route and origin of S. furcifera in Korea and will contribute to planthopper resistance management. PMID- 30301480 TI - Experimental combination therapy using low doses of benznidazole and allopurinol in mouse models of Trypanosoma cruzi chronic infection. AB - This study evaluated the effectiveness of low doses of benznidazole (BNZ) on continuous administration (BNZc), combined with allopurinol (ALO), in C57BL/6J and C3H/HeN mice infected with Trypanosoma cruzi Nicaragua strain and T. cruzi Sylvio-X10/4 clone. TcN-C57BL/6J was also treated with intermittent doses of BNZ (BNZit). The drug therapy started 3 months post infection (pi) in the chronic phase of mice with heart disease progression, followed-up at 6 months pi. TcN C57BL/6J treated with BNZc was also monitored up to 12 months pi by serology and electrocardiogram. These mice showed severe electrical abnormalities, which were not observed after BNZc or BNZit. ALO only showed positive interaction with the lowest dose of BNZ. A clear parasitic effect, with significant reductions in antibody titres and parasitic loads, was achieved in all models with low doses of BNZ, and a 25% reduction of the conventional dose showed more efficacy to inhibit the development of the pathology. However, BNZ 75 showed partial efficacy in the TcSylvio-X10/4-C3H/HeN model. In our experimental designs, C57BL/6J allowed to clearly define a chronic phase, and through reproducible efficacy indicators, it can be considered a good preclinical model. PMID- 30301482 TI - Parasite and host biomass and reproductive output in barnacle populations in the rocky intertidal zone. AB - The rocky intertidal zone has a long history of ecological study with barnacles frequently serving as a model system to explore foundational theories. Parasites are often ignored in community ecology studies, and this particularly holds for true for the rocky intertidal zone. We explore the role of the isopod parasite, Hemioniscus balani, on its host, the acorn barnacle, Chthamalus fissus. We use the currencies of biomass and reproduction measured at the individual level, then applied to the population level, to evaluate the importance of this parasite to barnacle populations. We found H. balani can comprise substantial biomass in 'apparent' barnacle populations, sometimes even equaling barnacle biomass. Additionally, parasite reproduction sometimes matched barnacle reproduction. Thus, parasites divert substantial energy flow from the barnacle population and to near-shore communities in the form of parasite larvae. Parasites appeared to decrease barnacle reproduction per area. Potentially, this parasite may control barnacle populations, depending on the extent to which heavily infected barnacle populations contribute to barnacle populations at larger scales. These findings regarding the importance of a particular parasite for host population dynamics in this well studied ecosystem call for the integration of disease dynamics into community ecological studies of the rocky intertidal zone. PMID- 30301483 TI - A tale of three kingdoms: members of the Phylum Nematoda independently acquired the detoxifying enzyme cyanase through horizontal gene transfer from plants and bacteria. AB - Horizontal gene transfer (HGT) has played an important role in the evolution of nematodes. Among candidate genes, cyanase, which is typically found only in plants, bacteria and fungi, is present in more than 35 members of the Phylum Nematoda, but absent from free-living and clade V organisms. Phylogenetic analyses showed that the cyanases of clade I organisms Trichinella spp., Trichuris spp. and Soboliphyme baturini (Subclass: Dorylaimia) represent a well supported monophyletic clade with plant cyanases. In contrast, all cyanases found within the Subclass Chromadoria which encompasses filarioids, ascaridoids and strongyloids are homologous to those of bacteria. Western blots exhibited typical multimeric forms of the native molecule in protein extracts of Trichinella spiralis muscle larvae, where immunohistochemical staining localized the protein to the worm hypodermis and underlying muscle. Recombinant Trichinella cyanase was bioactive where gene transcription profiles support functional activity in vivo. Results suggest that: (1) independent HGT in parasitic nematodes originated from different Kingdoms; (2) cyanase acquired an active role in the biology of extant Trichinella; (3) acquisition occurred more than 400 million years ago (MYA), prior to the divergence of the Trichinellida and Dioctophymatida, and (4) early, free-living ancestors of the genus Trichinella had an association with terrestrial plants. PMID- 30301484 TI - Effects of resveratrol and genistein on growth, nutrient utilization and fatty acid composition of rainbow trout. AB - The replacement of the finite and costly resource fish oil is an important task for aquaculture nutrition. A promising approach could be the use of plant bioactives that may have the potential to influence the metabolism and the synthesis of n-3 long chain polyunsaturated fatty acids, especially EPA (20:5n-3) and DHA (22:6n-3). In this study, the two phytochemicals resveratrol (RV) and genistein (G) were investigated for their effects on fish growth, nutrient utilization and body nutrient composition alongside their effects on whole body fatty acid (FA) composition. In a feeding trial lasting 8 weeks, rainbow trout (initial BW: 81.4+/-0.5 g) were held in a recirculating aquaculture system and fed six experimental diets with varying fish oil levels as plain variants or supplemented with 0.3% of dry matter (DM) of either RV or G. The six diets were as follows: diet F4 had 4% DM fish oil, diet F0 had 0% DM fish oil, diets F4+RV, F4+G, F0+RV and F0+G were equal to the diets F4 and F0, respectively, and supplemented with the phytochemicals RV and G. The feeding of the F0+RV diet resulted in reduced feed intake, growth rate and slightly reduced whole body lipid levels. At the same time, the amount of polyunsaturated FA and the n-3/n-6 ratio were significantly increased in whole body homogenates of rainbow trout fed diet F0+RV in comparison to the F0 control. The feeding of the F0+G diet led to reduced feed intake, slightly increased protein utilization but did not significantly affect the whole body FA composition. Overall, feeding the fish oil free diet supplemented with the phytochemicals resulted in more pronounced effects on fish performance and FA composition than the single factors per se (dietary fish oil level or phytochemical). Present data indicate that G might not be of profitable use for trout nutrition. In terms of FA composition, RV could be a potentially useful complement for fish oil. However, the impairment of growth and performance parameters as observed in the present study discourages its use in trout diets.

PMID- 30301485 TI - Operational experience with a full-scale Anaerobic Baffled Reactor treating municipal wastewater. AB - The aim of the study was to investigate the influence of moderate temperatures on the efficiency of a full-scale anaerobic treatment system consisting of a primary sedimentation unit (PST) and an Anaerobic Baffled Reactor (ABR, approx. 10 m3). Therefore, two trials with different test setups in series were carried out (1st trial: continuous load, 2nd trial: diurnal variated load). The plant was fed with municipal wastewater and operated at temperatures between 8 and 24 degrees C. The mean efficiency of the ABR was low, compared to the one of the PST. At 10 degrees C, only 10 % of the COD was removed. The COD removal efficiency of the plant (PST + ABR) averaged 50 %. At low temperatures, volatile fatty acids began to accumulate. In both trials, the contents of total suspended solids in the sludge bed differed distinctly and influenced the effort for desludging. PMID- 30301487 TI - A novel method for oxidative degradation of metanil yellow azo dye by hexacynoferrate(III) ions. AB - In the present work the degradation of metanil yellow an azo dye by hexacyanoferrate(III) ions (oxidant) in the aqueous alkaline medium has been investigated by kinetic - spectrophotometric method at lambdamax 435 nm of the reaction mixture. The effect of various parameters such as the concentration of dye, oxidant and solution pH on the reaction rate has been determined. The results show that the rate of degradation increases linearly with the increase in concentrations of oxidant and dye at optimum pH 9.0 and constant temperature of 40 +/- 0.1 degrees C. Thermodynamic parameters like energy of activation, enthalpy of activation, entropy of activation and energy of formation have been calculated by studying the reaction rate at four different temperatures, i.e. 40 55 0C. Based on the experimental results, a plausible reaction mechanism involving complex formation has been proposed and a rate law has been derived. UV Vis and LC-MS methods of analysis of degradation products show the formation of simpler and less hazardous degradation products. PMID- 30301488 TI - Surveillance on speed: Being aware of infectious diseases in migrants mass accommodations - an easy and flexible toolkit for field application of syndromic surveillance, Germany, 2016 to 2017. AB - Europe received an increased number of migrants in 2015. Housing in inadequate mass accommodations (MA) made migrants prone to infectious disease outbreaks. In order to enhance awareness for infectious diseases (ID) and to detect clusters early, we developed and evaluated a syndromic surveillance system in three MA with medical centres in Berlin, Germany. Healthcare workers transferred daily data on 14 syndromes to the German public health institute (Robert Koch Institute). Clusters of ID syndromes and single cases of outbreak-prone diseases produced a signal according to a simple aberration-detection algorithm that computes a statistical threshold above which a case count is considered unusually high. Between May 2016-April 2017, 9,364 syndromes were reported; 2,717 (29%) were ID, of those 2,017 (74%) were respiratory infections, 262 (10%) skin parasites, 181 (7%) gastrointestinal infections. The system produced 204 signals, no major outbreak was detected. The surveillance reinforced awareness for public health aspects of ID. It provided real-time data on migrants' health and stressed the burden of non-communicable diseases. The tool is available online and was evaluated as being feasible and flexible. It complements traditional notification systems. We recommend its usage especially when laboratory testing is not available and real-time data are needed.

AB - We summarised available hepatitis C virus (HCV) surveillance data for 2012-14 from Arctic/sub-Arctic countries/regions. We sent a HCV data collection template by email to public health authorities in all jurisdictions. Population statistics obtained from census sources for each country were used to estimate rates of reported acute and chronic/undifferentiated HCV cases. Seven countries with Arctic regions (Canada, Denmark, Finland, Greenland, Norway, Sweden and the United States, represented by the state of Alaska), including three Canadian territories and one province, as well as 11 Russian subnational Arctic regions, completed the data collection template. Data on acute HCV infection during 2014 was available from three Arctic countries and all Russian Arctic regions (rate range 0/100,000 population in Greenland, as well as Nenets and Chukotka Automous Okrugs (Russian subnational Arctic regions) to 3.7/100,000 in the Russian Republic of Komi). The rate of people with chronic/undifferentiated HCV infection in 2014 ranged from 0/100,000 in Greenland to 171.2/100,000 in Alaska. In most countries/regions, the majority of HCV-infected people were male and aged 19-64 years. Differences in surveillance methods preclude direct comparisons of HCV surveillance data between Arctic countries/regions. Our data can inform future efforts to develop standardised approaches to HCV surveillance in the Arctic countries/regions by identifying similarities/differences between the surveillance data collected.

AB - Cancer is the main cause of death in the developed countries. There are some scientific evidences indicating that parasitic infections induce antitumor activity against certain types of cancers. Hydatid cyst is the larval stage of Echinococcus granulosus, which causes hydatidosis in human and livestock. We have already shown that vaccination of mice with hydatid cyst crude antigens and subsequently challenge them with cancer cells, causes inhibition of melanoma cancer growth. In this study, therapeutic effects of hydatid cyst antigens on C57/black mice that had already been challenged with melanoma tumor were investigated. In this experimental study, 6 groups of C57 black mice were subcutaneously inoculated with melanoma cancer cells (line B16F10) in PBS inside their chest site. After 2 weeks case groups were injected with hydatid cyst fluid, a fraction of cyst fluid, live protoscolices or BCG. control groups were injected with alum alone and other control group was left intact without any intervention. The size of each tumor was measured in all mice. Blood samples were also taken to estimate Interleukin-2 (IL-2), Tumor necrosis factor alpha (TNF alpha), Interferon gamma (IFN-gamma) and Interleukin-4 (IL-4) levels. Treatment of mice bearing melanoma cancer with hydatid cyst antigens resulted in inhibition of tumor growth and the difference between mean size of tumor in case and control groups was statistically significant. Also, according to our results mean level of measured cytokines between case and control groups was statistically different. Hydatid cyst antigens have anti-melanoma activities and this effect may be related to immune response to parasite antigens. PMID- 30301495 TI - Boric acid protects against cyclophosphamide-induced oxidative stress and renal damage in rats. AB - The worldwide increase in the rate of cancer incidence also leads to a significant increase in the use of chemotherapeutic agents. Unfortunately, the optimal clinical usefulness of these agents is heavy restricted by a high incidence of several organ toxicity and as well reason oxidative stress and bring about changing in antioxidant status. Kidney toxicity is a side effect often encountered with cyclophosphamide (CPM) which is commonly used in most cancer chemotherapy. The present study aims on the assessment of the probable defensive efficacy of Boric acid (BA) against CPM-induced oxidative stress and renal damage in rats. Based upon our investigation results with oxidative stress markers and light microscopic findings, it can be concluded that BA significantly reduced CPM induced oxidative stress and renal damage. As far as we know, high dose (200 mg/kg) of BA are the first study on the prevention of kidney damage caused by CPM. It is thought that the renoprotective effects of BA may be due to an increase in the activity of the antioxidant protection system and also inhibition of lipid per oxidation. PMID- 30301492 TI - Screening for neurocysticercosis in internationally adopted children: yield, cost and performance of serological tests, Italy, 2001 to 2016. AB - IntroductionNeurocysticercosis (NCC) is one of the leading causes of epilepsy worldwide. The majority of cases in Europe are diagnosed in immigrants. Currently in Italy, routine serological screening for cysticercosis is recommended for internationally adopted children (IAC) coming from endemic countries. Methods: We retrospectively analyse the results of the serological screening for cysticercosis in IAC 16 years old or younger, attending two Italian third level paediatric clinics in 2001-16. Results: Of 2,973 children included in the study, 2,437 (82.0%) were screened by enzyme-linked immune electro transfer blot (EITB), 1,534 (51.6%) by ELISA, and 998 (33.6%) by both tests. The seroprevalence of cysticercosis ranged between 1.7% and 8.9% according to EITB and ELISA, respectively. Overall, 13 children were diagnosed with NCC accounting for a NCC frequency of 0.4% (95% confidence interval (CI): 0.2-0.6%). Among the 168 seropositive children, only seven (4.2%) were diagnosed with NCC. Of these children, three were asymptomatic and four presented epilepsy. Among seronegative children (n = 2,805), seven presented with neurological symptoms that lead to the diagnosis of NCC in six cases. The sensitivity, specificity, positive and negative predictive value for the diagnosis of NCC were 54.5%, 98.6%, 14.6%, 99.8% for EITB and 22.2%, 91.1%, 1.4%, 99.5% for ELISA. The yield of the screening programme was 437 NCC cases per 100,000. The number needed to screen to detect one NCC case was 228. The cost per NCC case detected was EUR 10,372. Conclusion: On the base of our findings we suggest the ongoing serological screening for cysticercosis to be discontinued, at least in Italy, until further evidence in support will be available. PMID- 30301494 TI - Establishment of a cochlear injury model using bone-conducted ultrasound irradiation in guinea pigs and investigation on peripheral coding and recognition of ultrasonic signals. AB - The cochlea of guinea pigs was irradiated with different frequencies of bone conducted ultrasound (BCU) at a specific dose to induce cochlear hair cell specific injuries, in order to establish frequency-related cochlear hair cell specific injury models. Cochlear near-field potentials were then evoked using BCU of different frequencies and intensities to explore the peripheral coding and recognition of BCU by the cochlea. The inner ears of guinea pigs were irradiated by 30 kHz at 100 db and 80 kHz at100 db BCU for 6h to create frequency-related, ultrasound-specific cochlear injury models. Then, 30 kHz and 80 kHz BCU of different intensities were used to evoke auditory brainstem response (ABR) thresholds, compound action potential (CAP) thresholds, and action potential (AP) intensity-amplitude input-output curves in the normal control group and the ultrasonic cochlear injury group. This allowed us to explore the coding and recognition of BCU frequencies and intensities by cochlear hair cells. Immunofluorescence assay of outer hair cell (OHC) Prestin and inner hair cell (IHC) Otofelin was performed to verify the injury models. Irradiation of guinea pig inner ears by 30 kHz and 80 kHz BCU at a specific dose induced hair cell injuries at different sites. Irradiation with low frequency BCU mainly induced OHC injury, whereas irradiation with high frequency BCU induced IHC injury; moreover, IHC injury was more serious than OHC injury. The 30 kHz-evoked ABR threshold was significantly higher in the 30 kHz ultrasonic cochlear injury group compared to the normal control group. The 30 kHz-evoked ABR threshold was significantly higher in the 30 kHz ultrasonic cochlear injury group compared to the 80 kHz ultrasonic cochlear injury group. The difference in the 80 kHz-evoked ABR thresholds were not significant between the 30 kHz and 80 kHz ultrasonic cochlear injury groups. The click- and 30 kHz-evoked AP intensity-amplitude curves for the 30 kHz ultrasonic cochlear injury group indicate that the AP amplitude evoked at the same intensity was higher in the 30 kHz-evoked group than the click-evoked group. The spatial positions of cochlear hair cells in guinea pigs had a coding function for the frequencies of low-frequency ultrasound. OHCs have an amplification effect on the coding of low-frequency ultrasonic intensities. The peripheral perception of high frequency BCU may not require the participation of cochlear hair cells. PMID- 30301496 TI - Keratinocytes contribute to the recruitment and M1 polarisation of macrophages during C. albicans colonisation. AB - Candida albicans (C. albicans) is an opportunistic human fungal pathogen that colonises the skin. Both keratinocytes and macrophages play crucial roles in host defence against C. albicans. However, the interaction of keratinocytes with macrophages during C. albicans colonisation has not been well studied. In this study, macrophages were cultured in conditioned medium from keratinocytes treated with heat-inactivated C. albicans (CM-C. albicans), macrophage migration and polarised activation and were then assessed by a Transwell assay, flow cytometry, quantitative real-time PCR (qPCR), Western blot and an enzyme-linked immunosorbent assay (ELISA). The results showed that CM-C. albicans-stimulated macrophages display significantly increased migration and phagocytosis, and they display an upregulation of proinflammatory cytokines (tumour necrosis factor alpha (TNF-a), interleukin (IL)-12 and nitric oxide (NO)). Markers characteristic of M1 macrophages, such as human leukocyte antigen (HLA)-DR, CD86 and inducible nitric oxide synthase (iNOS), are upregulated, whereas markers of M2 macrophages, such as mannose receptor (MR) and Arginase 1 (Arg1), are not affected. Additionally, the levels of TNF-a, IL-12 and monocyte chemotactic protein 1 (MCP 1) in CM-C. albicans are markedly upregulated, whereas the levels of IL-4 and IL 10 are not affected. And the CM-C. albicans-induced M1 macrophage polarisation, proinflammatory cytokine production and phagocytosis could be blocked by an anti TNF-a neutralising antibody. This study showed that keratinocytes may promote macrophage recruitment and M1 polarisation during C. albicans colonisation at least in part by secreting TNF-a.

AB - The efficient DNA extraction from insects has been suggested as a critical and main step affecting molecular entomology for taxonomic identification, the establishment of DNA barcoding library and analysis of genetic diversity relationship between insect populations. For successfully apply these molecular techniques, high-quantity and high-quality of the extracted DNA are required. Several protocols for efficient genomic DNA extraction from insects have been developed. In this research, we represent a rapid, reliable and cost-effective method that it is not reliant on poisonous and enzymatic reagents for DNA extraction from insect tissues. Results showed that high quantity and high quality of the isolated DNA by this method is suitable and can be used directly for PCR, also is enough to do hundreds of molecular reactions. In conclusion, we described a fast, cost-effective, non-toxic and enzyme-free protocol for high yield genomic DNA extraction from green Lacewings (Chrysoperla carnea) tissues in basic equipment laboratories.

AB - RT-qPCR (Quantitative real-time polymerase chain reaction) is a reliable molecular biology technique used for gene expression detection due to its high sensibility and good reproducibility. However, suitable reference genes for RT qPCR are often not available to investigate the expression of target genes in jellyfish under different conditions. To determine the responsible genes of jellyfish under hypoxia, primers to amplify the actin gene was designed for the amplification according to the conserved actin amino acid sequences of cnidarian. Then, we cloned and sequenced the partial cDNA sequence of beta-actin gene containing 849 bp nucleic acids was cloned and sequenced, and the four common housekeeping genes (18S rRNA, beta-actin, alpha-tubulin and GAPDH) were detected. To obtain suitable reference genes, we compared the four genes under normoxia and hypoxia were determined and compared using RT-qPCR. The evaluation result shows that alpha-tubulin gene can be used as single reference gene, and alpha-tubulin and beta-actin can be served as multiple reference genes to study relative gene expression related to hypoxic tolerance of Aurelia sp.1. This research will establish foundation to reveal the molecular mechanism of jellyfish under hypoxia. PMID- 30301499 TI - Hydrothermal synthesis of highly fluorescent and non-toxic carbon dots using Stevia rebaudiana Bertoni. AB - Herein, green, environmental-friendly and economical synthesize of luminescent carbon dots (CDs) was reported using the plant-based material, Stevia rebaudiana Bertoni, as a herbal bio-sweetener. In this regard, hydrothermal carbonization of Stevia was performed under mild conditions and without any chemical oxidizing agents. Exploring the morphological aspect, surface groups, chemical composition and structure of Stevia-based CDs have been carried out systematically using SEM EDS, TEM, fluorescence, FT-IR, UV-Vis, and XRD techniques. UV-Vis spectra displayed signature absorption of CDs at 240 nm related to the pi-pi* transitions of C=C. Fluorescence spectra showed characteristic emission at the peak wavelength of 431 nm with a quantum yield of approximately 17.5%. Moreover, there was no living cell cytotoxicity for the as-prepared CDs confirmed by confocal microscopy. These results indicated that these plant-based CDs are ideal non toxic promising markers for cellular bio-imaging. PMID- 30301500 TI - NET-1 promotes invasion, adhesion and growth of hepatocellular carcinoma by regulating the expression of BAX, caspase 3, caspase 8 and BCL2. AB - Dysregulation of neuroepithelial transforming gene-1 (NET-1) has been shown in hepatocellular carcinoma (HCC) patients. We aimed to evaluate the influence of NET-1 on HCC invasion, adhesion and growth. In vitro cellular functional assays including invasion and adhesion were performed to evaluate the effects of knockdown and overexpression of NET-1. HCC cells were transplanted into nude mice, and tumor growth was assessed. BAX, caspase 3, caspase 8 and BCL2 protein levels were detected by western blot. After transfection with NET-1 siRNA, NET-1 positive ratio in HCC cells significantly decreased. Cell invasion and adhesion assay showed that knockdown of NET-1 reduced the invasion and adhesion ability of HCC cells, whereas overexpression of NET-1 increased the ability. The evaluation of tumor growth revealed that NET-1 knockdown significantly decreased tumor volume and weight, while NET-1 overexpression promoted tumor growth in nude mice. Western blot showed that NET-1 knockdown increased BAX, caspase 3 and caspase 8 expression but decreased BCL2 expression, whereas NET-1 overexpression significantly down-regulated BAX, caspase 3 and caspase 8 expression but increased BCL2 expression. Our data suggest that NET-1 promotes HCC invasion, adhesion and growth by regulating BAX, caspase 3, caspase 8 and BCL2 expression. PMID- 30301501 TI - Screening of total phenolic, antiradical and antioxidant activities of Wiedemannia orientalis. AB - In this study, it was aimed to investigate total phenolic, antioxidant and antiradical activities of water and ethanolic extracts of the Wiedemannia orientalis (W. orientalis). In order to investigate the antiradical capacities, DPPH and ABTS radical scavenging activates were employed in the evaluation process. For the evaluation of antioxidant capacities, activities of phosphomolybdenum assay, reducing power and metal chelating were investigated. In the evaluations, the amounts of total phenolics were determined to be 11.95+/ 0.02-17.27+/-0.09 mg Gallic acid equivalents (GAE)/g in W. orientalis extracts, respectively. Additionally, the amount of reducing power and total antioxidant capacity of leaf ethanol extract of W. orientalis were determined to be higher compared to the other extracts of W. orientalis. While the highest activity was observed in flower ethanol extract on the DPPH radical scavenging activity, flower water extract demonstrated better results in metal chelating activity. In the ABTS radical chelating activity, no significant differences were observed. As a result, it was suggested in our study that extracts of W. orientalis could be regarded as a natural and alternative source in pharmacology and medicine and food sectors. Such results can be put to use in pharmaceutical formulations and may lead to the developments of new human drugs from this medicinal plant. PMID- 30301502 TI - Vitamin D can be used as a supplement against cancer stem cells. AB - Cancer is standing like a bottomless pit or a black hole in front of mankind. Scientists are trying all possible ways to find a solution against to cancer. As known, cancer is a phenomenon fed from internal dynamics. One of internal dynamic is cancer stem cells that are involved in the formation and development of cancer. Because of these dynamics, scientists began to search solution inside of the body. Another internal dynamic is vitamin D and it is not only important in calcium homeostasis but also it is important for cell proliferation, differentiation, and apoptosis. In this study, we investigated the effect of vitamin D on cancer stem cells that sorted from MCF-7 cell line and on HEK293 cell line as control. Our results showed that calcitriol treatment reduced the number of CSC (Cancer Stem Cell) in the MCF-7 cell while increased in HEK293 cell population. Gene expression analyses showed that effect of calcitriol on apoptosis plays an important role in this reduction. Deficiency or unavailability of vitamin D may take a role in the pathogenesis of breast cancer. PMID- 30301504 TI - Effects of melatonin on apoptosis and cell differentiation in MCF-7 derived cancer stem cells. AB - Melatonin is a hormone of the pineal gland that has a wide range of biological effects such as antioxidant, anti-inflammatory, and anti-tumor activity. Previous studies have shown that melatonin also affects survival, proliferation, and apoptosis of the cells. In this study, we investigated the effect of melatonin on apoptosis, self-renewal, and differentiation. For this purpose, MCF-7 and HEK293 cells were subjected to melatonin treatment. Expression of genes related to apoptosis (Bax and Bcl2) and self-renewal and differentiation (Oct4, Sox2, and Nanog) analyzed after the sorting of cancer stem cells from MCF-7 cells. Results showed that the effect of melatonin is dependent on the melatonin concentration and treatment periods. Melatonin treatment decreased the cell proliferation rate of MCF-7 in contrast to HEK293. Also, this treatment increased apoptosis in MCF-7 cells and decreased in HEK293 cells. Gene expression of Nanog was decreased and Sox2 was increased in both cell groups after the melatonin treatment. Expression of Oct4 was decreased in MCF-7 cells and increased in HEK293 cells. We determined that melatonin decreases apoptosis and differentiation of stem cells in normal HEK293 stem cells, but increases apoptosis and differentiation in the MCF-7 cancer stem cells. PMID- 30301503 TI - Serum levels of IL-31, IL-33 and ST2 in allergic rhinitis of children in China. AB - This study aimed to compare the serum levels of IL-31, IL-33 and ST2 in children patients with allergic rhinitis (AR) and allergic asthma and tried to reveal more insights in development of AR. Thirty-six children patients with intermittent AR were selected in the present study during January 2013 to December 2016. Two control groups were set, the allergic asthma group and the healthy individuals. Atopic status of all participants in this study was tested and confirmed by skin prick testing (SPT). Levels of IL-31, IL-33 and ST2 were determined using ELISA. Statistical analysis was performed by SPSS 18.0. There is no significant difference in age, gender ratio and BMI for all patients. However, positive ratio of SPT and total IgE in patients' groups were significantly higher than the control group. Levels of IL-33 and IL-31 in both AR and allergic asthma group were significantly higher than those of the control group, P<0.05. However, level of ST2 in the three groups didn't show significant difference. Correlation analysis showed that there was a positive correlation between levels of IL-33 and IL-31, P<0.05. However, levels of ST2 and IL-33, ST2 and IL-31 were not significantly correlated. The serum levels of IL-33 and IL-31 were significantly up-regulated in both AR and allergic asthma patients compared with normal individuals. These results could provide more clinical evidences for understanding roles of IL-33, IL-31 and ST2 in children patients with allergic rhinitis. PMID- 30301505 TI - Effect of cobalt nanoparticles and cobalt ions on alkaloids production and expression of CrMPK3 gene in Catharanthus roseus suspension cultures. AB - The capabilities of cobalt ions (Co2+) and cobalt nanoparticles (CoNPs) in enhancing alkaloids accumulation in Catharanthus roseus suspension cultures were evaluated in relation to the expression of CrMPK3 gene. Four concentrations (5, 10, 15 and 20 mg/L) of each cobalt form were utilized in addition to control. Both forms induced oxidative stress that was more pronounced for Co2+ treatments. A positive correlation was observed between cobalt concentration and expression of CrMPK3 gene. However, a characteristic temporal expression profile was recorded for each cobalt form. Also, positive correlations were detected between both cobalt concentration and expression of CrMPK3 gene on one hand and the activities of antioxidant enzymes (SOD and APX) and alkaloids content on the other hand. Such correlations suggest CrMPK3 gene as a common player in cobalt induced stress signaling; regardless of cobalt form. Results revealed the higher capability of Co2+, compared with CoNPs, in enhancing alkaloids accumulation. However, results supported CoNPs as a novel tool in manipulating cobalt-induced alkaloids production in C. roseus. PMID- 30301506 TI - SMAR1 promotes immune escape of Tri-negative Breast Cancer through a mechanism involving T-bet/PD-1 Axis. AB - This study was aimed at investigating the specific molecular mechanisms involved in the regulation of immune escape of triple-negative breast cancer (TNBC) by SMRI, so as to provide a new clinical treatment target for the disease. Mouse original 4T1 breast cancer cells were inoculated subcutaneously in BALB/C to establish TNBC mouse model. CD8+T cells with immunological effects were selected from mouse thymus glands for primary culture. The CD8+positive T cells were infected with lentivirus interference vectors, and the proliferation of CD8+ T cells were determined by trypan blue staining and flow cytometry. CD8+T cells and 4T1 cells were cultured together so as to determine the cytotoxic effects of SMAR1-downregulated CD8+ T cells on tumor cells and the expression of cytokines (IFN-gamma, TNF-alpha, IL-2, IL-4 and IL-6). The expressions of SMAR1, T-bet and PD-1 were assayed by Western blot. SMAR1-downregulated CD8+T cells were injected into 4T1 tumor-bearing mice through the caudal vein, and the growth of tumor in mice was monitored. Following the infection of CD8+T cells with SMAR1 downregulated lentiviral system, cell apoptosis level was decreased significantly (control vs. sh-SMAR1: 32.23 +/- 12.4 % vs. 18.28 +/- 8.93 %, p < 0.05). Results from trypan blue staining experiments showed that the proliferation of CD8+ T cells in the SMAR1-downregulated group was significantly increased; SMAR1 downregulated CD8+ T cells promoted the production of IFN-gamma, TNF-alpha, IL-2, IL-4 and IL-6 in 4T1 breast cancer cells (p < 0.05). Western blot showed that SMAR1 down-regulation led to significant upregulation of T-bet, while PD-1 was downregulated, when compared to the control group (p < 0.05). The downregulation of SMAR1 was associated with significant reduction in tumor size in mice (p < 0.05). SMAR1 downregulation enhances the tumor killing effect of CD8+T cells by activating T-bet and down-regulating PD-1. PMID- 30301507 TI - Characterization of antioxidant activity of sulfur compounds in black garlic. AB - Different types of sulfur compounds, namely S-allyl-L-cysteine (SAC), S-allyl-L cysteine sulfoxide (ACSO) and a synthetic gamma-L-glutamyl-S-allyl-L-cysteine (GSAC) were extracted from black garlic and their inhibition to the advanced glycation end-products (AGEs) were investigated. Upon addition of inhibitor, the amount of produced fructosamine was determined by UV visible spectroscopy. The change of pentosidine and fluorescent AGEs during reaction was detected by fluorescence method and the change of carboxymethyl lysine (CML) was detected by high performance liquid chromatography. It was found that the inhibitory effects of SAC and ACSO are stronger to the early and mid non-fluorescent products in glycosylation reaction, and GSAC has an obvious inhibitory effect on the later reaction products. All these three inhibitors can effectively inhibit advanced glycation reaction. Although their effects on glycation products are different due to different chemical structures, they have similar inhibitory effects on fluorescent products. PMID- 30301508 TI - Omentin Val/Val genotype increases predisposition to acne vulgaris without changing omentin serum level. AB - Acne vulgaris is the most frequent and multifactorial inflammatory skin disorder in all races. Obesity is considered to be a risk factor for acne due to its contribution to inflammation. The involvements of inflammatory (leptin and resistin) and anti-inflammatory (adiponectin) adipokines in the pathogenesis of acne were reported. Omentin resembles adiponectin in terms of having inhibitory effect on tumor necrosis factor-alpha (TNF-alpha) induced inflammation, a vital process in the acne formation. This study was designed to investigate the putative involvement of omentin in acne formation. The genotyping was performed by restriction fragment length polymorphism (RFLP) method. Serum omentin protein levels were analyzed by enzyme-linked immunosorbent assay (ELISA). Serum omentin level was not significantly changed between groups. However, the decreased serum omentin level was observed as the mean value of BMI increased. The Asp/Asp, Val/Asp and Val/Val genotypes distributions for control and patient groups (19[17.4%], 22[20.2%], and 3[2.8%] respectively, vs. 31[28.4%], 25[22.9%], and 9[8.3%], respectively) were obtained. The Val/Val (mutant homozygote) genotype was found nearly 1.8 times more in the patient group (p=0.403, OR=1.839 (0.442 7.653)). This is the first time to clarify a linkage between anti-inflammatory omentin and acne vulgaris. Omentin Val109Asp polymorphism affects the overall function of the protein. In conclusion, omentin Val/Val (mutant homozygote) genotype increases predisposition to acne vulgaris by probably disrupting overall protein function of omentin. PMID- 30301509 TI - Roscovitine and Trichostatin A promote DNA damage repair during porcine oocyte maturation. AB - Faithful repair of DNA double-strand breaks in mammalian oocytes is essential for meiotic maturation and embryonic development. In the present study we investigated the roles of Roscovitine and Trichostatin A (TSA) in DNA damage recovery during in vitro maturation of porcine oocytes. Etoposide was used to trigger DNA damage in oocytes. When these DNA-damaged oocytes were treated with 2 MUM Roscovitine, 50 nM TSA or both for 22 h, first polar body extrusion and blastocyst formation in all treated groups were significantly improved compared with the etoposide-only group. The most significant improvement was observed when Roscovitine was present. Further immunofluorescent analysis of gammaH2A.X, an indicator of DNA damage, indicated that DNA damage was significantly decreased in all treated groups. This observation was further supported by analysing the relative mRNA abundance of DNA repair-related genes, including meiotic recombination 11 homolog A (MRE11A), breast cancer type 1 susceptibility protein (BRCA1), Recombinant DNA Repair Protein 51 (RAD51), DNA-dependent protein kinase catalytic subunit (PRKDC) and X-ray cross complementing gene 4 (XRCC4). Compared with the etoposide-only group, the experimental group with combined treatment of Roscovitine and TSA showed a significant decrease of all genes at germinal vesicle and MII stages. The Roscovitine-only treatment group revealed a similar tendency. Together, these results suggest that Roscovitine and TSA treatments could increase the capacity of oocytes to recover from DNA damage by enlisting DNA repair processes. PMID- 30301511 TI - Foreword. PMID- 30301510 TI - Follicular environment as a predictive tool for embryo development and kinetics in cattle. AB - Follicular fluid composition and the transcription pattern of granulosa cells were analysed to better comprehend associations between embryo development and morphokinetics. Bovine follicles were punctured and their respective follicular fluid and granulosa cells were collected. Cumulus-oocyte complexes derived from these follicles were matured and fertilised in vitro. Embryo morphology and kinetics were evaluated at 40 h after insemination, when embryos were classified as fast (FCL, four or more cells), slow (SCL, 2-3 cells) or non-cleaved (NCL). Their development was followed until the blastocyst stage. Glucose, pyruvate, cholesterol and oestradiol were quantified in the follicular fluid and the transcription pattern of 96 target genes was evaluated in granulosa cells by large-scale quantitative reverse transcription polymerase chain reaction. Follicular fluid from the blastocyst group had increased levels of glucose, total cholesterol and pyruvate compared to the non-blastocyst group, whereas higher levels of oestradiol were observed in the follicular fluid of embryos and blastocysts with fast cleavage. The transcriptional pattern revealed altered metabolic pathways between groups, such as lipid metabolism, cellular stress and cell signalling. In conclusion, both follicular fluid and granulosa cells are associated with the possibility of identifying follicles that may generate embryos with high potential to properly develop to the blastocyst stage. PMID- 30301512 TI - Hypervascular Pseudonodular Plaque-Like Ultrasound Morphology in Angiolymphoid Hyperplasia. AB - Angiolymphoid hyperplasia with eosinophilia (ALHE) is a benign vascular proliferation characterized by solitary or multiple angiomatous lesions. It is most common in young or middle-aged women, and the lesions typically affect the head and neck, showing a particular predilection for the periauricular region. The differential diagnosis in patients with ALHE is broad and includes both benign and malignant conditions. We report on a series of cases of periauricular ALHE in which ultrasound imaging revealed an hypervascular, pseudonodular and plaque-like morphology with clinical and histologic correlations. It also evidenced vascular communication between lesions that appeared to be separate on clinical examination. Familiarity with such ultrasound presentations could help to improve diagnostic accuracy and facilitate disease monitoring in patients with ALHE. PMID- 30301513 TI - Kalman Inversion Stress Microscopy. AB - Although mechanical cues are crucial to tissue morphogenesis and development, the tissue mechanical stress field remains poorly characterized. Given traction force time-lapse movies, as obtained by traction force microscopy of in vitro cellular sheets, we show that the tissue stress field can be estimated by Kalman filtering. After validation using numerical data, we apply Kalman inversion stress microscopy to experimental data. We combine the inferred stress field with velocity and cell-shape measurements to quantify the rheology of epithelial cell monolayers in physiological conditions, found to be close to that of an elastic and active material.

AB - Simian virus 40 (SV40) is a possible vehicle for targeted drug delivery systems because of its low immunogenicity, high infectivity, and high transfection efficiency. To use SV40 for biotechnology applications, more information is needed on its assembly process to efficiently incorporate foreign materials and to tune the mechanical properties of the structure. We use atomic force microscopy to determine the effect of double-stranded DNA packaging, buffer conditions, and incubation time on the morphology and strength of virus-like particles (VLPs) composed of SV40 VP1 pentamers. DNA-induced assembly results in a homogeneous population of native-like, ~45 nm VLPs. In contrast, under high ionic-strength conditions, the VP1 pentamers do not seem to interact consistently, resulting in a heterogeneous population of empty VLPs. The stiffness of both in-vitro-assembled empty and DNA-filled VLPs is comparable. Yet, the DNA increases the VLPs' resistance to large deformation forces by acting as a scaffold, holding the VP1 pentamers together. Both disulfide bridges and Ca2+, important in-vitro-assembly factors, affect the mechanical stability of the VLPs: the reducing agent DTT makes the VLPs less resistant to mechanical stress and prone to damage, whereas Ca2+-chelating EDTA induces a marked softening of the VLP. These results show that negatively charged polymers such as DNA can be used to generate homogeneous particles, thereby optimizing VLPs as vessels for drug delivery. Moreover, the storage buffer should be chosen such that VP1 interpentamer interactions are preserved.

AB - BACKGROUND: Medical student reflection is integral for professional development. Preliminary findings suggest that short-format writing promotes reflection and identifies impactful experiences. We sought to determine whether reflective writing could be used as a clerkship needs assessment. METHODS: During their surgical clerkship, medical students submitted "tweet"-format reflections and completed a standardized evaluation. "Tweet" content was analyzed using modified grounded theory methods and coded by valence, content, and reflection. Sub-coding was conducted to compare feedback between "tweets" and evaluations. RESULTS: We analyzed 286 reflections and 214 evaluation comments; 176 "tweets" were reflective (62%). "Tweets" commented on "patient interaction" (53%), "educational experience" (38%), "physician interaction" (26%), and "career decisions" (10%). A significant difference was observed between "tweets" and evaluations with regard to the number that provided feedback on experiences with "critically ill or dying patients." CONCLUSIONS: Reflections provided real-time reactions to impactful clerkship events, notably those involving critically ill or dying patients. This focus on illness may represent an unmet need for discussions related to end of life care. Overall, reflections provided more actionable feedback compared to evaluations. PMID- 30301519 TI - Mechanistic insight into protein supported biosorption complemented by kinetic and thermodynamics perspectives. AB - In this review, we discussed the micro-level aspects of protein supported biosorption. The mechanism, surface chemistry in terms of energy interactions and electron transfer process (ETP) of peptide systems within protein are three important areas that provide mechanistic insight into protein supported biosorption. The functional groups in proteinous material like hydroxyl (-OH), carbonyl (>C=O), carboxyl (-COOH) and sulfhydryl (-SH) play a significant role in the biosorption of variety of pollutants such as metal ions, metalloids, and organic matters in wastewaters. The mechanistic aspects of biosorption are crucial not only for the separation process but also they contribute towards stoichiometric considerations and mathematical modelling process. The surface chemistry of applied biosorbents relies on interfacial components whose interaction energies are estimated with help of classical Derjaguin, Landau, Verwey, and Overbeek (DLVO) theory mathematically. Proteins are the fundamental molecules of many biomaterial used for the biosorption of contaminents and peptide bond is considered as the backbone of proteins. The charge variations on peptide bonding is the result of ETP whose discussion was made part of this review for understaning number of biological and technological processes of vital interests. In addition, this review was complemented by exhaustive overview of kinetic and thermodynamics perspectives of biosorption process.

PMID- 30301521 TI - Risk factors for systemic inflammatory response syndrome after percutaneous nephrolithotomy. AB - OBJECTIVES: To explore the risk factors for systemic inflammatory response syndrome (SIRS) after percutaneous nephrolithotomy (PCNL). METHODS: A retrospective chart review was performed to identify 1030 patients who had undergone PCNL from January 2014 to July 2016 in the Minimally Invasive Surgery Center. Multiple data, including age, sex, body mass index (BMI), operation time, Staghorn calculi, diabetes, Serun creatinine, preoperative urine culture and the urinary sediment microscopy white blood cell (WBC) were collected. These factors and postoperative SIRS were retrospectively analyzed. RESULTS: There were 108 cases (10.49%) of SIRS among 1030 patients. The results of univariate analysis showed that sex (P=0.015), Staghorn calculi (P<0.001), preoperative urinary culture of Gram-negative bacteria (P<0.001) and preoperative urinary sediment microscopy WBC (+, ++, +++, ++++) (P<0.001, P<0.001, P=0.009, P=0.045) were correlated with postoperative SIRS (P<0.05). According to Multivariate analysis results, the likelihood of SIRS after PCNL increased with Staghorn calculi (P=0.01, OR=10.457, 95% CI=1.312-3.092), the urinary sediment microscopy WBC (+~++++) (P<0.001, OR=2.591, 95% CI=1.661-4.042) and positive urine culture for Gram-negative bacteria (P<0.001, OR=3.550, 95% CI=2.205-5.715). CONCLUSIONS: Staghorn calculi, the urinary sediment microscopy WBC and positive urine culture for Gram-negative bacteria are independent risk factors for SIRS. Patients affected by these risk factors should receive careful anti-infectious perioperative management for prevention of postoperative SIRS. LEVEL OF INCIDENCE: 4. PMID- 30301522 TI - Novel biomarkers in multiple myeloma. AB - Significant advancements have been made in the molecular mechanisms of myelomagenesis, diagnostic methods, prognostication, and the treatment options in multiple myeloma (MM) over the last decade. Despite these, MM remains a heterogeneous disease with differing outcomes. As myeloma treatment landscape continues to expand, personalized treatment that provides maximum benefit to a specific patient becomes more important. In the last few years, serum monoclonal proteins including the serum-free light chain assays, imaging, and cytogenetics have been used to predict the outcomes of MM patients receiving different types of therapies. With the development of novel technologies, more sensitive detection of residual disease using flow cytometry and next-generation sequencing has been possible. In addition, liquid biopsies using circulating tumor cells, tumor DNA, and novel immune biomarkers are potentially being investigated. These novel potential biomarkers not only accurately detect the mutational landscape of different cancers compared to standard methods but also serve as prognostic and predictive biomarkers for disease relapse and response to therapy. It is likely that we will be able to offer more targeted and risk-adapted therapeutic approach to patients with MM at different stages of their disease guided by these potential biomarkers.

PMID- 30301524 TI - Promoting oral potassium administration in a tertiary care hospital: An eleven year study. AB - INTRODUCTION: Potassium is used to treat or prevent hypokalemia and exhibits all the characteristics of an intravenous to oral therapy conversion program. Despite this, the intravenous route for potassium replacement seems frequently unjustified. OBJECTIVES: To determine the impact of a conversion program on the use of intravenous and oral galenic forms in a university tertiary care hospital. METHODS: Two promotion campaigns were conducted in 2006 and 2009. The following years this was completed by pharmacist interventions during prescription analysis and face-to-face discussions with physicians during ward rounds. The consumption of products containing potassium was obtained by analyzing the hospital's financial database. RESULTS: The proportion of the oral route increased from 18% in 2006 to 22% in 2011, and from 25% in 2012 to 44% in 2016; the increase was significantly greater in the second period (P<0.0001). In 2016, in emergency, pulmonology, infectious diseases, and cardiology departments, the proportion of oral use ranged from 57% and 82%. The greatest progression from 2006 to 2016 was found for intensive care (4% vs. 12%) and visceral surgery departments (9% vs. 34%) that increased approximately four-fold, followed by the emergency department (28% vs. 57%) that increased approximately two-fold. CONCLUSION: Promoting the oral route for potassium replacement modifies prescriber habits and is followed by a notable increase in the proportion of potassium administered orally irrespective of department type. PMID- 30301525 TI - Antibiotic anisomycin selectively targets leukemia cell lines and patient samples through suppressing Wnt/beta-catenin signaling. AB - Chronic myeloid leukemia (CML) responds well to BCR-ABL tyrosine kinase inhibitors (TKI), such as imatinib and dasatinib. However, these inhibitors have been less effective as single agents in the blast phase-CML. In this work, we show that anisomycin, a clinically available drug, targets CML cells at all stages of development and enhances BCR-ABL TKIs' efficacy. Anisomycin at nanomolar concentration inhibits proliferation and induces apoptosis in a panel of CML cell lines in a dose-dependent manner. It induces apoptosis CD34 stem/progenitor cells isolated from patients with blast phase CML. Using colony formation and serial replating assays, we further show that anisomycin inhibits CML CD34 cell differentiation, proliferation and self-renewal. Additionally, anisomycin is less effective in normal bone marrow (NBM) CD34 cells, suggesting the selective anti-leukemia activity of anisomycin. Combination of anisomycin with imatinib or dasatinib achieves significantly better efficacy than TKI alone in leukemia cell lines and patient samples while sparing normal counterparts. Mechanistically, we demonstrate that p38 MAPK/JNK activation is not required for anti-leukemia activities of anisomycin. Instead, anisomycin displays preferential inhibitory effects to Wnt/beta-catenin-mediated signaling in CML. Our work provides the preclinical evidence on the potent efficacy of anisomycin in leukemia and its mechanisms of action. Our work suggests that anisomycin is a potential drug to overcome resistance to BCR-ABL TKI treatment in blast phase CML. PMID- 30301526 TI - Transgelin-1 (SM22alpha) interacts with actin stress fibers and podosomes in smooth muscle cells without using its actin binding site. AB - Transgelin-1 (SM22alpha) has been recognized as a smooth muscle marker and a tumor suppressor, but many details of the working mechanisms remain unclear. Transgelin-1 belongs to the calponin family of actin-binding proteins with an N terminal calponin homology domain (CH-domain) and a C-terminal calponin-like module (CLIK23). Here, we demonstrate that transgelin-1 interacts with actin stress fibers and podosomes in smooth muscle cells via its type-3 CH-domain, while CLIK23 is dispensable for the binding to the actin structures. We further suggest that the EF-hand motif in transgelin-1 contributes to proper folding of the CH-domain and in turn to the interaction with the actin structures. These results are in contrast to the ones reported in in vitro studies that demonstrated CLIK23 was necessary for the transgelin-1-actin binding, while the CH-domain was not. Besides, within cells, transgelin-1 phosphorylation at Ser181 in CLIK23 did not affect its colocalization with the actin structures, while the same phosphorylation was reported in in vitro studies to negatively regulate actin binding. Thus, our results suggest the molecular basis of intracellular interaction between transgelin-1 and actin, distinct from that in vitro. The actin binding capability intrinsic to CLIK23 may not appear within cells probably because of the weaker competition for actin binding compared to other actin binding molecules. PMID- 30301527 TI - Interleukin-18 binding protein attenuates lipopolysaccharide-induced acute lung injury in mice via suppression NF-kappaB and activation Nrf2 pathway. AB - Interleukin (IL)-18 belongs to a rather large IL-1 gene family and is a proinflammatory cytokine. IL-18 plays important roles in lung injury. IL-18 binding protein (IL-18BP), a natural antagonist of IL-18, binds IL-18 with high affinity. IL-18BP is able to neutralize IL-18 biological activity and has a protective effect against renal fibrosis. The aim of this study was to evaluate the potential protective effect of IL-18BP on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice and to illuminate the underlying mechanisms. Results indicated that pretreatment with IL-18BP significantly attenuated LPS induced pulmonary pathological injury. Meanwhile, IL-18BP pretreatment markedly inhibited infiltration of inflammatory cell and release of inflammatory factor in ALI mice in vivo and in primary macrophages after LPS insult in vitro. IL-18BP treatment dramatically reduced oxidative stress through increasing superoxide dismutase (SOD) and glutathione (GSH) contents, and decreasing the levels of malondialdehyde (MDA) and reactive oxygen species (ROS) in LPS-induced ALI mice and primary macrophages. Additionally, IL-18BP was also observed to markedly decreased the activation of nuclear factor-kappa B (NF-kappaB) and upregulated the nuclear factor erythroid 2-related factor 2 (Nrf2). Taken together, IL-18BP possessed protective effect against LPS-induced ALI, which might be associated with its regulation of NF-kappaB and Nrf2 activities. The results rendered IL 18BP worthy of further development into a pharmaceutical drug for the treatment of ALI. PMID- 30301528 TI - Helicobacter pylori flagellin: TLR5 evasion and fusion-based conversion into a TLR5 agonist. AB - Helicobacter pylori is a flagellated bacterium of the Epsilonproteobacteria class that causes peptic ulcers. Flagellin is a primary structural protein that assembles into the flagellar filament. Flagellins from bacteria that belong to the Gammaproteobacteria and Firmicutes groups are detected by Toll-like receptor 5 (TLR5) in the host, triggering the innate immune response, and thus have been studied for the development of vaccines against diverse infections through fusion with protein antigens. However, H. pylori flagellin (hFlg) does not stimulate TLR5, allowing H. pylori to evade TLR5-mediated immune surveillance. The unresponsiveness of TLR5 to hFlg, along with the tendency of the hFlg protein to precipitate, limits the utility of hFlg for H. pylori vaccine development. Here, we report a soluble hFlg derivative protein that activates TLR5. We performed expression and purification screens with full-length and fragment hFlg proteins and identified the hypervariable domains as the soluble part of hFlg. The hypervariable domains of hFlg were engineered into a TLR5 agonist through fusion with the TLR5-activating Bacillus subtilis flagellin. Furthermore, based on comparative sequence and mutation analyses, we reveal that hFlg evolved to evade TLR5 detection by modifying residues that correspond to a TLR5-activation hot spot. PMID- 30301529 TI - Short fish-origin DNA elements served as flanking sequences in a knockdown cloning vector enabling the generation of a functional siRNA molecule in mammalian cells and fish embryos. AB - Improving the quality of a siRNA-knockdown cloning vector requires simpler, shorter, and more effective flanking sequences. In this study, we designed such flanking sequences based on those found in zebrafish pre-miR3906, namely, internal element (IE) 1 and IE2. We engineered a vegf-shRNA fragment flanked by an 80-bp IE1/IE2 and then inserted into the 3' UTR of GFP reporter cDNA driven by a cytomegalovirus promoter to obtain a plasmid containing gfp-IE-vegf-shRNA-polA. Upon microinjection of this plasmid into zebrafish embryos, we found that IE flanking sequences could effectively induce the production of vegf-shRNA fragment, which was then processed into a functional siRNA to silence the target vegf121 gene. Northern blot showed that the vegf-shRNA fragment was cleaved from gfp-IE-vegf-shRNA-polA, resulting in the loss of polyA tails, subsequently degrading the remaining RNA-containing GFP. Moreover, Western blot revealed that addition of IE-based vegf-shRNA fragment could markedly decrease the expression of VEGF. Finally, to facilitate a more versatile application of the IE-based knockdown vector, we generated an inducible expression vector in which IE-vegf shRNA was constructed downstream in a Tet-on system to generate a Tet-on-IE-vegf shRNA construct. After doxycycline induction, the protein level of VEGF in SW620 cells harboring the Tet-on-IE-vegf-shRNA construct was decreased 77%. Interestingly, when SW620 cells harboring Tet-on-IE-vegf-shRNA cells were induced and transplanted into zebrafish embryos, we found that abnormal branch of the sub intestinal vessels was reduced in the recipient embryos, suggesting that vegf shRNA cleaved from Tet-on-IE-vegf-shRNA-polA was processed into a functional vegf siRNA in embryos suppressing endogenous VEGF and reducing tumor angiogenesis. Therefore, we conclude that fish-origin IEs are flanking sequences with short, simple, and effective DNA elements. This IE-based knockdown cloning vector provides a new alternative material to facilitate the generation of functional siRNA with which to perform loss-of-function experiments, both in vitro (mammalian cells) and in vivo (zebrafish embryos). PMID- 30301530 TI - Far upstream element-binding protein 1 is up-regulated in pancreatic cancer and modulates immune response by increasing programmed death ligand 1. AB - Pancreatic ductal adenocarcinoma (PDAC) is one of the leading causes of cancer related death worldwide. So far, almost all treatments are almost ineffective for pancreatic cancer. Thus, there is an urgent need to develop novel therapeutics for pancreatic cancer treatment. Immune checkpoints blockade therapies, including anti-PD-L1 and anti-PD-1, show promising anti-tumor efficacy for a various type of solid tumors. However, pancreatic cancer is disappointed for anti-PD-L1 therapy alone. The expression level of PD-L1 is considered as one of determinant of checkpoint immunotherapy efficacy. The far upstream element-binding protein 1 (FUBP1) is an important transactivator of c-Myc proto-oncogene. Here, we demonstrate that FUBP1 is overexpressed in pancreatic cancer and associated with poor prognosis. Moreover, we show that FUBP1 promotes tumor cell proliferation and migration and regulates the cancer cell immunity by increasing the PD-L1 expression mediated by Myc in pancreatic cancer cells. Taken together, these findings uncover important aspects of the function of FUBP1 in cancer immunity and elucidated the specific mechanism regulating PD-L1 expression. Targeting FUBP1 may be a novel therapeutic strategy to overcome the immunotherapy resistance in pancreatic cancer. PMID- 30301531 TI - Real-time monitoring of IL-6 and IL-10 reporter expression for anti-inflammation activity in live RAW 264.7 cells. AB - In previous study, we suggested that the interleukin (IL)-6 and IL-10 could serve as a good biomarker for anti-inflammation that related to chronic inflammatory disease. Recently, we are finding new anti-inflammation compounds from natural products by screening of IL-6 and IL-10 levels. Although, we could measure IL-6 and IL-10 levels by several methods. However, all methods could not measure continuous kinetic of IL-6 and IL-10 levels. Most methods have multiple steps and take a long time. Therefore, there is no a suitable method for screening. To this end, we established IL-6 and IL-10 promoter assay which can monitor with reference gene as Glyceraldehyde 3-phosphate dehydrogenase (gapdh) promoter in living single cell. It could determine IL-6 and IL-10 levels continuously in real time within two steps. We evaluated IL-6 and IL-10 reporter expression in LPS induced RAW 264.7 cells with well-known anti-inflammatory compounds such as quercetin, xanthones, beta-D-glucan and dexamethasone. As the results, the expression of IL-6 and IL-10 reporters were strongly induced by LPS. The expression of IL-6 reporter was inhibited by all anti-inflammation compounds in LPS-induced RAW 264.7 cells. The expression of IL-10 reporter was inhibited by quercetin, xanthones and dexamethasone in LPS-induced RAW 264.7 cells. While, expression of IL-10 reporter was induced by beta-D-glucan. These results indicated that this assay could use for determination of IL-6 and IL-10 reporter expression in LPS-induced RAW 264.7 cells for anti-inflammation activity. Moreover, the results showed that natural compounds have an effect on the time course of IL-6 and IL-10 expressions. Therefore, real-time monitoring has a merit for natural compounds screening. We suggested that this assay could serve as a compound screening assay for anti-inflammation activity. PMID- 30301533 TI - CTLA-4 regulates T follicular regulatory cell differentiation and participates in intestinal damage caused by spontaneous autoimmunity. AB - Cytotoxic T lymphocyte-associated protein 4 (CTLA-4) is a co-inhibitory molecule expressed by T cells and is required for immune regulation and inflammation prevention. In clinical patients, the CTLA-4 mutation causes spontaneous immune related early-onset Crohn's disease; however, its potential mechanism is still unknown. In the current study, we found that defects in CTLA-4 in CD4 cells lead to limited differentiation of T follicular regulatory (Tfr) cells and relatively increased T follicular helper (Tfh) cells and spontaneous B cell germinal centres (GCs) responses that trigger the accumulation of autoantibodies in intestinal epithelial cells. In addition, the deficiency of Tfr cells caused by defects in CTLA-4 causes these cells to lose their function of inhibiting the non-specific immune response produced during the specific humoural immune response induced by MCMV (mouse cytomegalovirus), resulting in acute intestinal injury and death in mice. The lack of Tfr cells may be responsible for the immunosuppressive disorder of inflammatory bowel disease caused by CTLA-4 deficiency. In conclusion, we verified that CTLA-4 may be required for Tfr cell differentiation and production. Tfr cells inhibit B cell responses and prevent humoural autoimmune-mediated intestinal damage by regulating Tfh-dependent GC responses. PMID- 30301532 TI - Deletion of ApoM gene induces apoptosis in mouse kidney via mitochondrial and endoplasmic reticulum stress pathways. AB - Apolipoprotein M (ApoM) is involved in lipid metabolism, and especially is involved in reverse cholesterol transport. However, the relationship between ApoM and apoptosis has been rarely reported. This study aimed to investigate the effect of ApoM on apoptosis using an ApoM gene-deficient mice (ApoM-/-) model and a mouse mesangial cell model with suppressed ApoM gene expression. First, we observed by transmission electron microscopy that mitochondrial damage and endoplasmic reticulum stress were abnormally altered in the kidneys of ApoM-/- mice compared with wild-type mice, showing mitochondrial swelling, vacuolization, myeloid changes, and expansion of the rough endoplasmic reticulum. At the molecular level, the expression of pro-apoptotic related proteins such as AIF, Bax, chop, clever-caspase 3, clever-caspase 7, clever-caspase 9, and clever caspase 12 increased, and the expression of anti-apoptotic protein Bcl-2 decreased. Secondly, by interfering with the expression of the ApoM gene in mouse mesangial cells, we found that, compared with the control group (NC-si), the cells of the experimental group (siApoM) showed decreased cell viability, nuclear chromatin condensation, nuclear lysis, and an increased proportion of early apoptotic cells. The results in cells at the molecular level were consistent with those at the tissue level. These data indicated that the deletion of the ApoM gene led to upregulation of apoptosis in mouse kidney tissues and mesangial cells through the mitochondrial and endoplasmic reticulum pathways.

PMID- 30301538 TI - Mobility is a fundamental human right: Factors predicting attitudes toward self directed mobility. AB - BACKGROUND: Emergent disability studies research is interested in the community's views on how disability, including self-directed mobility, influences social and environmental policies. We anticipate that individuals' alignment with disability models, or sets of assumptions about the cause, nature, and treatment of disability, will influence attitudes about self-directed mobility. Self-directed mobility is defined as mobility that is controlled by an individual and may include walking or assisted ambulation through the use of mobility technology such as prosthetics, walking aids, manual wheelchairs, or motorized wheelchairs. OBJECTIVE: The purpose of this study was to explore how demographic factors, contact with people with disabilities, attitudes toward people with disabilities, and alignment with social or medical models of disability predict attitudes toward self-directed mobility. METHODS: 1545 students at a public university completed demographic questions, and measures of disability attitudes, disability model orientation, and self-directed mobility. RESULTS: The predictors explained 16.60% of the variance in participants' attitudes toward self-directed mobility (R2 = 0.166, F(7,1537) = 43.9, p < .001). Significant predictors included: female gender (beta = -0.14, p < .01), more positive attitudes toward people with disabilities (beta = -0.30, p < .001), and social model orientation (beta = 0.59, p < .001). CONCLUSIONS: Participants who more strongly agreed with disability as a social construct (social model) were in stronger agreement that self-directed mobility is a fundamental right. Future research extending to rehabilitation professionals is warranted.

Although mechanisms might differ, coronary artery disease is an important cause of morbidity in this group. Limited data are available on the outcomes of acute myocardial infarction (AMI) in HT in comparison to general population (non-HT). The study population was extracted from the National Readmissions Data 2014 using International Classification of Diseases, Ninth Revision, Clinical Modification codes for AMI and HT. The study outcomes included in-hospital all-cause mortality, length of hospital stay (LOS), cardiogenic shock, acute kidney injury, the likelihood of receiving invasive left-sided cardiac catheterization with and/or without percutaneous coronary intervention (PCI) and 30-day readmission rates. A total of 259,794 discharges with a principal diagnosis of AMI were identified, in which 789 had a history of HT. In comparison to non-HT, HT group was associated with longer LOS (5.9 vs 4.9 days, p <0.01), more cardiogenic shock (8.8% vs 6.4%, p <0.01), more acute kidney injury (26.2% vs 17.6%, p <0.01), less catheterization (59.7% vs 75.1%, p <0.01), less use of PCI (35.2% vs 50.0%, p <0.01), and higher 30-day readmission rate (21.3% vs 14.4%, p <0.01). However, there was no statistically significant difference in all-cause mortality (6.8% vs 5.4%, p = 0.07). In conclusion, compared with non-HT, HT with AMI was associated with longer LOS, more in-hospital morbidity, lower likelihood of receiving invasive treatment (including PCI), and higher 30-day readmission rates. There was no significant difference in all-cause mortality. PMID- 30301542 TI - Raising the Bar by Lowering the Target: Integrating PCSK9 Inhibitors Into Hypercholesterolemia Management. AB - This CME-accredited CME Snapshot seven-part series is intended for interventional cardiologists, other cardiologists, lipidologists, endocrinologists, and other diabetologist physicians involved in the ongoing management of patients with persistent hypercholesterolemia. During these activities, expert faculty will participate in a series of interactive discussions on the latest evidence and their clinical experience managing patients with persistently elevated low density lipoprotein cholesterol levels using nonstatin lipid-lowering medications, including inhibitors of the enzyme protein convertase subtilisin or kexin type 9 (PCSK9). (Online access: https://lipidsnapshotcme.elsevierresource.com/.). PMID- 30301543 TI - Patterns of Acute Myocardial Infarction in Taiwan from 2009 to 2015. AB - Most studies about the trends of acute myocardial infarction (AMI) were based on the data from Western countries. In recent years, little information is available from Asia since 2010. This study assessed the nationwide trends of AMI in Taiwan from 2009 to 2015. Using data from the Taiwan National Health Insurance Research Database, we identified 100,570 adult patients hospitalized for AMI from 2009 to 2015 and examined the temporal trends in the incidence of AMI. Overall, the age- and gender-adjusted incidence of AMI (per 100,000 persons) remained constant from 49.8 in 2009 to 50.7 in 2015. The incidence of AMI increased 30.3% and 29.4% in the young male and female populations (<55 years), whereas in other age groups, the incidence decreased or remained unchanged. The ratio of non-ST-segment elevation MI (NSTEMI) to STEMI incidence increased from 1.93 in 2009 to 2.47 in 2015. In young men (<55 years), a 49.8% increase in NSTEMI was observed. The prevalence of dyslipidemia increased significantly and it was the most common risk factor of AMI in young patients. Despite being increasingly used, percutaneous coronary intervention and secondary preventive medications, including dual antiplatelet therapy, angiotensin converting enzyme inhibitor/angiotensin receptor blocker, beta blocker and statin, were less prescribed for NSTEMI compared with STEMI. The in-hospital mortality of STEMI continued to decrease from 2013 to 2015 (8.8% to 7.6%), but not in NSTEMI (13.3% to 13.5%). In conclusion, our study revealed a marked increase of NSTEMI in young Taiwanese male population in recent years. Despite the increased utilization of percutaneous coronary intervention and guideline-recommended medications, the overall in-hospital mortality of NSTEMI remained stagnating in Taiwan. PMID- 30301544 TI - [Unusual cause of Takotsubo cardiomyopathy after pacemaker implantation]. AB - Since its first description in Japan in 1990, Takotsubo (stress) cardiomyopathy has gained worldwide recognition. The disease is characterized by transient systolic and diastolic left ventricular dysfunction with a variety of wall-motion abnormalities. She predominantly affects elderly women and she is often preceded by an emotional or physical trigger. In the acute phase, the clinical presentation, electrocardiographic findings and biomarker profiles are often similar to those of an acute coronary syndrome. Although, the cause of Takotsubo cardiomyopathy remains unknown, the role of the brain-heart axis in the pathogenesis of the disease has been described. The potential role of catecholamine excess in the pathogenesis of Takotsubo cardiomyopathy has been long debated, and as such beta-blockers have been proposed as a therapeutic strategy. Currently, the treatment is not codified and it adapts according to clinical symptomatology. It seems difficult to summarize all the factors to provoque the cardiomyopathy, we describe a case of Takotsubo after a pacemaker (PM) implantation and to give a recent progress on this heart disease. PMID- 30301545 TI - [Place of the exercise stress test at the sportsman]. AB - Is the stress test still part of the useful examinations in the detection of risk heart disease in sports subjects? Should we continue to use it as a surveillance examination in coronary sports patients? Meta-analysis, considering a ST subshift of more than 1mm as a criterion for positivity, underline the low prevalence of abnormal examinations and a significant rate of false-positives. But for the diagnosis of coronary artery disease, it is mainly the evolution of the ST segment to effort or recovery and the occurrence of stress arrhythmias that detect true positivity. When coronary risk is more important (presence of risk factors, resumption of sport, intense and prolonged efforts), it seems lawful to recommend such a review on a regular basis among men over 40 years of age with two risk factors but Also among veterans taking up sport after a period of prolonged inactivity. For the asymptomatic coronary athlete the stress test remains at the centre of the final decision for the resumption of a sport in competition irrespective of the method of revascularization. Of course the stress test, even inevitable, remains flawed in the detection of coronary artery disease in the asymptomatic athlete. However, it provides additional information on the condition of being maximal, and attaching importance to arrhythmias, the tensional profile and the maximum power developed in addition to the ST segment's only study. PMID- 30301546 TI - [Infectious endocarditis: Experience of a cardiology department at Oran university hospital]. AB - INTRODUCTION: Infectious endocarditis (IE) is a serious disease that has continued to evolve in diagnostic and therapeutic terms. AIM: To analyze the diagnostic and out come profile. METHODS: We collected 57 (IE) cases with a definite diagnosis according to the modified Duke criteria. Patients were admitted consecutively to the Cardiology Department of the Oran university hospital from January 2011 to June 2017. Among the variables studied: clinical data, paraclinic data, therapeutic management and hospital outcome. RESULTS: The mean age was 40.5+/-15 years (extreme 16-67 years), with a male predominance (sex ratio=1.5). This was a native valve IE in 70% of cases, on valve prosthesis in 15.5% of patients, on congenital heart disease in 2% and on pacemaker probe in 4% of cases. The entrance door was dominated by oral origin. Blood cultures were positive only in 51% of cases. The most commonly implicated organism in staphylococci in 22.6%, streptococcus in 18.9% and brucellosis in 3.8%. Ultrasound data revealed vegetation (83%), cardiac abscess (19%), valvular perforation (15.1%) and prosthesis disintegration (7.5%). Complications were mainly neurological complications (27%) and hemodynamics (26%). Cardiac surgery occurred in 29% of patients. Hospital mortality was 26%, predictive factors were staphylococcal AI (P<0.001), cardiac insufficiency (P<0.001) and neurological complications (P=0.04). CONCLUSION: Infectious endocarditis is a serious disease in the absence of surgery. The diagnosis is based on echocardiography in the first place and blood cultures. The population is often young revealing the EI by complications; its prevention is the best way to improve its prognosis.

AB - Today by the e-health and the telemedicine, many people are more and more interested by the improvement of disease knowledge on cardiovascular diseases and associated risk factors, personalized self management support follow-up and e Health monitoring. MGEN is a not-for-profit complementary health insurance gave itself the ways to use the new digital tools in health. MGEN developed an original and personalized program VIVOPTIM for the primary prevention of the cardiovascular risks for their members. The VIVOPTIM Pilot program is based upon digital services and was experimented by November 2015 to December, 2017 with 8000 members of the MGEN, from 30 to 70 years old and resident in two French areas (Occitanie and Bourgogne Franche-Comte). The assessment of the experiment VIVOPTIM e -health program was positive for the personalized cardiovascular support and for their health. Therefore, the MGEN generalized the VIVOPTIM program of cardiovascular prevention, to the whole France on July 11th, 2018. PMID- 30301549 TI - Thrombocytopenia independently predicts death in idiopathic PAH. AB - BACKGROUND: Pulmonary arterial hypertension (PAH) is a progressive vascular disorder with a high mortality. Clinical experience and small case series suggest thrombocytopenia may be frequent in this population and associated with a poor prognosis. We sought to estimate the prevalence of thrombocytopenia in patients with PAH and characterize its association with disease characteristics and patient outcome. METHODS: Single center cohort study of 714 incident adult patients with Group 1 PH who were evaluated for baseline platelet count at the time of diagnosis. Pts were stratified into three groups: normal platelet count (>150 * 109/L), Grade 1 thrombocytopenia (75-149 * 109/L) and Grade 2-4 thrombocytopenia (<75 * 109/L). RESULTS: The median platelet count was 209 * 109/L (IQR 163, 264). There were 572 (80%) pts without thrombocytopenia, 107 (15%) with Grade 1 and 35 (5%) with Grade 2-4 thrombocytopenia. The median pt age was 55years (IQR 44-65) with no difference between platelet groups (p = 0.85). Men were more likely to have thrombocytopenia (62, 34%) than women (80, 15%, p < 0.0001). Thrombocytopenia was frequent with portopulmonary PAH (84%) as opposed to idiopathic PAH (iPAH; 14%) or connective tissue disease associated PAH (12%). Platelet counts were not associated with functional class symptoms, the degree of right ventricular enlargement or dysfunction or tricuspid regurgitation by echocardiography. Invasive hemodynamics of right atrial pressure, mean pulmonary artery pressure and pulmonary vascular resistance were also similar between platelet groups. Thrombocytopenia was associated with higher mortality in iPAH patients (age- and sex-adjusted 5 year mortality [HR 1.95 (1.20, 3.08) p = 0.008] but not in other etiology groups. In a multivariate model of iPAH patients (adjusted for age, sex, DLCO, PVR, creatinine and 6MW distance) thrombocytopenia was most predictive of 5-year mortality [HR 1.68 (1.32, 2.12), p < 0.0001]. CONCLUSION: Thrombocytopenia in the context of iPAH portends a poor prognosis and is a simple independent factor to consider in judging severity of disease. PMID- 30301550 TI - Does the activity of ankle plantar flexors differ between limbs while healthy, young subjects stand at ease? AB - Inferences on the active contribution of plantar flexors to the stabilisation of human standing posture have been drawn from surface electromyograms (EMGs). Surface EMGs were however often detected unilaterally, presuming the myoelectric activity from muscles in a single leg reflects the pattern of muscle activation in both legs. In this study we question whether surface EMGs detected from plantar flexor muscles in both legs provide equal estimates of the duration of activity. Arrays of surface electrodes were used to collect EMGs from gastrocnemius and soleus muscles while twelve, young male participants stood at ease for 60 s. Muscles in each leg were deemed active whenever the Root Mean Square amplitude of EMGs (40 ms epochs) detected by any channel in the arrays exceeded the noise level, defined from EMGs detected during rest. The Chi-Square statistics revealed significant differences in the relative number of active periods for both muscles in 10 out of 12 participants tested, ranging from 2% to 65% (chi2 > 17.90; P < 0.01). Pearson correlation analysis indicated side differences in the duration of gastrocnemius though not soleus activity were associated with the centre of pressure mean, lateral position (R = 0.60; P = 0.035). These results suggest therefore that surface EMGs may provide different estimates of the timing of plantar flexors' activity if collected unilaterally during standing and that asymmetric activation may be not necessarily associated with weight distribution between limbs. Depending on the body side from which EMGs are collected, the active contribution of plantar flexors to standing stabilization may be either under- or over-valued.

AB - Carbon black (CB) suspension exhibits various structures depending on the properties of solvent and dispersant as well as the preparation process of suspension. In most cases, CB particles do not exist as independent nanoparticles but as aggregates or agglomerates. In order to evaluate the size distribution at different level of hierarchal structure, we carried out static/dynamic ultrasound scattering analysis for the CB suspensions in alcohol and/or water with or without Nafion, a perfluorinated polymer. The potential of the dynamic ultrasound scattering technique was demonstrated by discriminating diffusing nanoparticles and micron-sized aggregates/agglomerates without dilution of the sample. Particularly, suppression of large agglomerates by addition of Nafion was clearly observed. Phosphotungstic acid (PWA), a family of polyoxometalate, was also employed to obtain smaller unit structures of the CB particles without formation of aggregation after decomposition of CB. The possible structures of the CB/PWA suspensions with and without Nafion were also discussed. PMID- 30301552 TI - Nonlinear scattering and mode conversion of Lamb waves at breathing cracks: An efficient numerical approach. AB - This article presents an efficient numerical approach to the investigation of nonlinear scattering and mode conversion phenomena of Lamb waves as they interact with breathing cracks. A Local Interaction Simulation Approach (LISA) is adopted, which possesses the versatility to capture arbitrary damage profiles. The stick slip contact dynamics is implemented in the LISA model via the penalty method, which captures the nonlinear interactions between Lamb waves and breathing cracks. The LISA framework achieves remarkable computational efficiency with its parallel implementation using Compute Unified Device Architecture (CUDA) executed on powerful GPUs. A small-size LISA model with absorbing boundaries is tailored for the purpose of extracting the Lamb wave scattering and mode conversion features. Due to the explicit parallel CUDA implementation and the small-size model setup, the computation is highly efficient. Numerical case studies on nonlinear scattering of Lamb waves from breathing cracks are given. Distinctive higher harmonic generation and selective mode conversion phenomena are presented using the complex-valued Wave Damage Interaction Coefficients (WDICs) containing both amplitude and phase information of the scattered wave field. The effect of oblique incident angle on nonlinear scattering phenomenon is investigated. The rough crack surface feature with initial openings and closures is also considered to better approximate fatigue cracks in practical engineering scenarios. In addition, the wave amplitude effect on the nonlinear scattering and mode conversion is studied. This research may provide guidelines for the effective design of sensor arrays utilizing nonlinear Lamb waves for fatigue crack detection.

AB - INTRODUCTION: Based on the radiological responses obtained with a schedule of ten mg/kg every two weeks bevacizumab was approved by the FDA for recurrent glioblastomas. Due to the negative results concerning overall survival of patients receiving bevacizumab, the European application was rejected. Despite this, many centers apply an off-label prescription. Our aim was to evaluate the safety and efficacy of schedules of low doses of bevacizumab. METHODS: From September 2013 to August 2016, we recruited patients with progressive glioblastoma, whatever the previous treatments. We compared a routine control group (CG) of ten mg/kg, to a low dose group (LDG) composed of 5 subgroups: G5: five mg/kg, G4: four mg/kg, G3: three mg/kg, G2: two mg/kg, G1: one mg/kg; each patient was treated with the same dose every two weeks. RESULTS: Fifty-three patients were treated: 20 women and 33 men, 24 in the CG and 29 in the LDG. The median age at diagnosis was 62 years [35.0-77.0]. No statistical difference was found in overall survival either for the CG or the LDG (P=0.086) or among groups (P=0.251), with even a trend toward improvement for LDG: 62 weeks [20-145] versus 73 weeks [18-178]. The median progression free survival was comparable: 19.5 weeks [6.0-54.0] for the CG and 15.0 weeks [0.0-134.0] for the LDG (P=0.221). Bevacizumab was stopped either due to progression (45.1%) or toxicity (52.9%), without significant differences between doses but maybe less toxicities in the LDG (16.7% for toxicity in G1). DISCUSSION: Use of bevacizumab at progression at lower than usual doses seems to give the same results as the standard dose without giving additional toxicity. PMID- 30301555 TI - Intralesional Macular Atrophy in Anti-Vascular Endothelial Growth Factor Therapy for Age-Related Macular Degeneration in the IVAN Trial. AB - PURPOSE: To report on the development and progression of macular atrophy (MA) and its relationship with morphologic and functional measures in study and fellow eyes in the Inhibition of vascular endothelial growth factor (VEGF) in Age related Choroidal Neovascularisation trial. DESIGN: Reading center analysis of data from a randomized controlled trial. PARTICIPANTS: Participants with previously untreated neovascular age-related macular degeneration (nAMD) in the study eye. METHODS: Color, fluorescein angiography (FA) and OCT images acquired at baseline and during the 2-year follow-up were graded systematically for presence of MA. Regression models were constructed to explore relationships between MA and lesion morphology and vision measures (best-corrected distance and near acuity, reading speed and index, contrast sensitivity). MAIN OUTCOME MEASURES: Primary outcome was development of intralesional MA (>=175 MUm greatest linear dimension of choroidal vessels seen on FA and/or color, aided by OCT) lying within the maximum footprint of the neovascular lesion. RESULTS: Study eye data were available for 594 of 610 participants; 57 (9.6%) showed intralesional MA at baseline. Incident intralesional MA occurred in 24.4% by the final visit and extralesional MA in only 1.54%. In fellow eyes, an established nAMD lesion was present at baseline in 248 of whom 42 (16.9%) showed intralesional MA at baseline and 32 (12.9%) developed incident intralesional MA. The odds of incident intralesional MA by final visit were lower in study eyes that had >=50% classic CNV at baseline (odds ratio [OR], 0.39; 95% confidence interval [CI], 0.19-0.80; P = 0.010), subretinal fluid at final visit (OR, 0.41; 95% CI, 0.25-0.76; P = 0.004), or pigment epithelial detachment at final visit (OR, 0.40; 95% CI, 0.21 0.74; P = 0.004). Secondary analyses of incident or progressed intralesional MA in study eyes supported these findings, with odds increasing if the fellow eye had baseline intralesional MA (OR, 2.43; 95% CI, 1.09-5.44; P = 0.030). No significant associations were observed between development of intralesional MA and any other morphologic or visual function measure. CONCLUSIONS: Macular atrophy frequently develops within an nAMD lesion in eyes receiving anti-VEGF therapy over 2 years. No associations between incident MA and drug or treatment frequency or visual function were detected, providing some reassurance to clinicians; however, the longer-term effects remain unknown. PMID- 30301556 TI - Blood pressure targeting by partial REBOA is possible in severe hemorrhagic shock in pigs and produces less circulatory, metabolic and inflammatory sequelae than total REBOA. AB - BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an effective adjunct in exsanguinating torso hemorrhage, but causes ischemic injury to distal organs. The aim was to investigate whether blood pressure targeting by partial REBOA (pREBOA) is possible in porcine severe hemorrhagic shock and to compare pREBOA and total REBOA (tREBOA) regarding hemodynamic, metabolic and inflammatory effects. METHODS: Eighteen anesthetized pigs were exposed to induced controlled hemorrhage to a systolic blood pressure (SBP) of 50 mmHg and randomized into three groups of thoracic REBOA: 30 min of pREBOA (target SBP 80-100 mmHg), tREBOA, and control. They were then resuscitated by autologous transfusion and monitored for 3 h. Hemodynamics, blood gases, mesenteric blood flow, intraperitoneal metabolites, organ damage markers, histopathology from the small bowel, and inflammatory markers were analyzed. RESULTS: Severe hemorrhagic shock was induced in all groups. In pREBOA the targeted blood pressure was reached. The mesenteric blood flow was sustained in pREBOA, while it was completely obstructed in tREBOA. Arterial pH was lower, and lactate and troponin levels were significantly higher in tREBOA than in pREBOA and controls during the reperfusion period. Intraperitoneal metabolites, the cytokine response and histological analyses from the small bowel were most affected in the tREBOA compared to the pREBOA and control groups. CONCLUSION: Partial REBOA allows blood pressure titration while maintaining perfusion to distal organs, and reduces the ischemic burden in a state of severe hemorrhagic shock. Partial REBOA may lower the risks of post-resuscitation metabolic and inflammatory impacts, and organ dysfunction. PMID- 30301557 TI - Beyond the pillars of the ankle: A prospective randomized CT analysis of syndesmosis' injuries in Weber B and C type fractures. AB - BACKGROUND: This study compared clinical and radiographic results of patients who underwent stabilization of syndesmosis with one tricortical syndesmotic screw divided into three different groups: Group A without preoperative fractured ankle computed tomography (CT) scan, Group B with preoperative fractured CT scan, and Group C with preoperative bilateral ankle CT analysis. METHODS: Between June 2016 and May 2017, fifty-one patients with fracture type AO/OTA 44 B and C were analyzed. Of those, 14 (27.45%) were assigned to Group A, 19 (37.25%) to Group B, and 18 (35.30%) to Group C. Clinical outcomes with AOFAS score at 3, 6 and 12 months were recorded. Seven measurements on axial CT scan images were confronted between the injured and uninjured ankle to check the accuracy of reduction. RESULTS: At three months of follow up the median AOFAS score was 70.86 +/- 2.98 with no significative difference between groups (p = 0.105). At 12 months of follow up the median AOFAS score was higher in group C (93.44 +/- 3.01) compared to Group B and Group C. The seven variables measured at the CT scan after syndesmotic reduction were statistically different between groups. We found a better restoration of the tibiofibular distances and the correct ankle anatomy in Group C respect to Group A and Group B. CONCLUSIONS: Use of the pre-operative CT scan of the injured and uninjured ankle give to the surgeons the more and accurate information for the reduction and help him intraoperative in the correct maneuvers. The accuracy of the syndesmosis reduction determines better clinical outcomes. PMID- 30301558 TI - Sleep problems and suicide risk in youth: A systematic review, developmental framework, and implications for hospital treatment. AB - OBJECTIVE: Sleep problems are transdiagnostic symptoms that confer significant risk for suicidal thoughts and behaviors (STBs) in adults. However, less is known about the sleep-STB association in adolescence-a developmental period when rates of STBs increase drastically, and sleep problems may be particularly pernicious. This article provides a systematic review of research on the sleep-STB association in youth, an overview of changes in sleep regulation during adolescence that may make sleep problems particularly detrimental for youth, and a discussion of the clinical implications of the sleep-STB association for hospitalized youth. METHOD: The systematic review included all longitudinal studies in which sleep problems were examined as prospective predictors of STBs in adolescents (aged 10-24 years). The search was conducted on December 1, 2017 using PsychINFO, PubMed, and Web of Science databases. RESULTS: Ten studies qualified for inclusion in this review. Of these, seven studies found at least one type of sleep problem significantly predicted a STB outcome. CONCLUSIONS: Although findings are mixed, growing research suggests that sleep problems may be a unique risk factor for STBs in youth. Sleep problems may be particularly important intervention target because they are easily assessed across healthcare settings and are amenable to treatment. PMID- 30301559 TI - External validation of a multifactorial normal tissue complication probability model for tube feeding dependence at 6 months after definitive radiotherapy for head and neck cancer. AB - BACKGROUND AND PURPOSE: The purpose of this study was to externally validate a previously published normal tissue complication probability (NTCP) model for tube feeding dependence at 6 months (TUBEM6) after completion of (chemo) radiotherapy. MATERIALS AND METHODS: This study evaluated 122 head and neck cancer patients treated by definitive (chemo) radiotherapy. The closed testing procedure was used to select the appropriate method for updating the NTCP model. In this procedure, the likelihood ratio test was used to compare the updated model against the original model. RESULTS: Mean predicted NTCP was 12.2% (95% CI: 9.9%-14.5%) when using the original NTCP model for TUBEM6. TUBEM6 at our institute was 5.7% (95% CI: 1.8-9.6%) for the 122 patients evaluated. The test for the model revision against the original NTCP model was statistically significant (p = 0.032). The test for the model revision against the model adjusting intercept only was not statistically significant (p = 0.240). According to the closed testing procedure, the model required adjusting the intercept only. CONCLUSIONS: TUBEM6 at our institute was lower than that predicted by the original NTCP model. The closed testing procedure indicated that only an adjustment of the intercept was needed indicating the importance of external validation. PMID- 30301560 TI - Evaluating class III antiarrhythmic agents as novel MYC targeting drugs in ovarian cancer. AB - OBJECTIVE: To evaluate the utility of amiodarone and its derivative dronedarone as novel drug repositioning candidates in EOC and to determine the potential pathways targeted by these drugs. METHODS: Drug-predict bioinformatics platform was used to assess the utility of amiodarone as a novel drug-repurposing candidate in EOC. EOC cells were treated with amiodarone and dronedarone. Cell death was assessed by Annexin V staining. Cell viability and cell survival were assessed by MTT and clonogenics assays respectively. c-MYC and mTOR/Akt axis were evaluated as potential targets. Effect on autophagy was determined by autophagy flux flow cytometry. RESULTS: "DrugPredict" bioinformatics platform ranked Class III antiarrhythmic drug amiodarone within the top 3.9% of potential EOC drug repositioning candidates which was comparable to carboplatin ranking in the top 3.7%. Amiodarone and dronedarone were the only Class III antiarrhythmic drugs that decreased the cellular survival of both cisplatin-sensitive and cisplatin resistant primary EOC cells. Interestingly, both drugs induced degradation of c MYC protein and decreased the expression of known transcriptional targets of c MYC. Furthermore, stable overexpression of non-degradable c-MYC partially rescued the effects of amiodarone and dronedarone induced cell death. Dronedarone induced higher autophagy flux in EOC cells as compared to amiodarone with decreased phospho-AKT and phospho-4EBP1 protein expression, suggesting autophagy induction due to inhibition of AKT/mTOR axis with these drugs. Lastly, both drugs also inhibited the survival of EOC tumor-initiating cells (TICs). CONCLUSIONS: We provide the first evidence of class III antiarrhythmic agents as novel c-MYC targeting drugs and autophagy inducers in EOC. Since c-MYC is amplified in >40% ovarian tumors, our results provide the basis for repositioning amiodarone and dronedarone as novel c-MYC targeting drugs in EOC with potential extension to other cancers.

AB - One woman dies from cervix cancer every 2 min, adding up to over 270,000 deaths globally per year. This cancer affects a young population, and hence, the loss of life is staggering. There are many aspects of prevention, screening, and care that are suboptimal. A great deal is known about HPV induced carcinogenesis, yet clinical outcomes have been stagnant over decades. There has been no improvement in cervix cancer survival in the US since the mid-1970s [1]. With increased knowledge of the disease and greater worldwide resources including prevention, screening, and improved therapeutics, there is significant promise for fewer women to die from this virally induced cancer. We focus here on the major problems in prevention, screening, and delivery of care for cervix cancer and provide concrete solutions. With appropriate focus, a major improvement in survival from cervix cancer could be achieved in a short time span.

PMID- 30301563 TI - Hyperbaric oxygen boosts long noncoding RNA MALAT1 exosome secretion to suppress microRNA-92a expression in therapeutic angiogenesis. AB - BACKGROUND: Hyperbaric oxygen (HBO) could improve wound healing by enhancement of angiogenesis. The effect of HBO on metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), a proangiogenic long noncoding RNA, and on endothelial cell-derived exosome is unknown. We aim to investigate both whether MALAT1 is altered in human coronary artery endothelial cells (HCAECs)-derived exosomes in response to HBO as well as the molecular regulatory mechanisms of MALAT1 in HCAECs under HBO treatment. METHODS AND RESULTS: HCAECs were cultured and HBO was applied at 2.5 atmosphere absolute (ATA) in a hyperbaric chamber. Exosomes were extracted from culture media. A rat model of hind-limb ischemia was performed by ligation of the right femoral artery. HBO at 2.5 ATA significantly increased MALAT1 expression in HCAECs and HCAECs-derived exosomes. MALAT1 suppressed miR 92a expression in HCAEC-derived exosomes under HBO. Silencing MALAT1 by MALAT1 siRNA significantly inhibited KLF2 mRNA expression induced by HBO, as did MiR 92a. MiR-92a significantly decreased KLF2 luciferase activity in HCAECs under HBO. HBO and HBO-induced exosomes significantly increased cell proliferation and the capillary-like network formation of HCAECs. MALAT1 siRNA and miR-92a overexpression significantly attenuated the cell proliferation and tube formation caused by HBO-induced exosome. HBO and HBO-induced exosomes significantly improved neovascularization in a rat model of hind-limb ischemia. CONCLUSIONS: HBO upregulates MALAT1 to suppress miR-92a expression and counteracts the inhibitory effect of miR-92a on KLF2 expression in HCAECs to enhance neovascularization. HBO-induced derivation of exosomes from HCAECs enhances angiogenesis. Exosomes containing MALAT1 might serve as a valuable therapeutic tool for neovascularization by HBO.

AB - Before the creation of a therapeutic patient education (TPE) program for epilepsy surgery, a needs analysis was conducted with 29 people, including patients (n=13), family members (n=9) and healthcare providers (n=7). Most of them highlighted the psychological difficulties of the surgical process, and the need for considerably more precise information concerning the immediate postoperative period. In addition, several patients and/or family members requested meeting with a patient who had undergone the surgery. The majority of subjects were interested in epilepsy-surgery TPE. These data were important in the creation of our TPE program and, more generally, for the management of these patients.

PMID- 30301569 TI - [Sexual violence against women in Tunisia]. AB - BACKGROUND: Sexual violence exists everywhere in the world. It depends mainly on the cultural and religious norms conveyed in the various societies. This is a neglected area of research. Available data are insufficient, especially in Arab Muslim context. METHODS: In this paper, we comprehensively review the scientific literature in order to clarify the cultural, religious and legal aspects of the concept of sexual violence against women in Tunisia, and ask the question of the urgent need to put in place strategies to counter this problem. RESULTS: The National Office for Family and Population published in 2011 the results of the national survey on violence against women in Tunisia, including data on sexual violence and its impact on women's health and well-being. According to this survey, 14.2% of women reported having been sexually abused by an intimate partner during their lifetime and 9.0% reported having experienced it during the last 12 months. One out of every six Tunisian women has been the victim of a sexual violence in a conjugal setting. More men than women legitimized violence against women in contexts where family control, especially conjugal control, is exercised over them. In a study examining the impact of culture and religion on experiences and sexual practice of women in Tunisian society, the majority of respondents thought that sexuality in women was a religious duty and that they do not have the right to refuse their husbands or to rebel. Thus, women would be doubly sanctioned having neither the right to express their desire nor not to respond to their husband's desire. A survey of a representative sample of Tunisian women found that 56.9% of the participants reported being victims of domestic violence, particularly sexual violence (10.7%) consisting mainly of rape and sodomy, at least once in their lifetime. This survey showed that those victims expressed dissatisfaction with overall quality of life. Moreover, contrary to Western literature, sexual violence was the least reported form of violence by teenage girls in Tunisian schools. Indeed, cultural values of modesty, virginity and honor are socially much more demanded for girls, in Arab countries in general, reinforcing staggering silence and inaction around violence experienced by school-aged adolescents. In Tunisian society, the cultural "solution" to rape wants the woman to marry her rapist which safeguards her family's integrity by legitimizing the union. CONCLUSION: Sexual violence has detrimental effects on female victims' physical and mental health. Even if the information on this form of violence is not easy to obtain in our environment, and that rates of subjects reporting sexual violence in their lifetimes are not important, the problem of sexual violence must be considered as a public health problem requiring urgent interventions and a greater institutional will. PMID- 30301568 TI - Hydroxypropyl-beta-cyclodextrin protects from kidney disease in experimental Alport syndrome and focal segmental glomerulosclerosis. AB - Studies suggest that altered renal lipid metabolism plays a role in the pathogenesis of diabetic kidney disease and that genetic or pharmacological induction of cholesterol efflux protects from the development of diabetic kidney disease and focal segmental glomerulosclerosis (FSGS). Here we tested whether altered lipid metabolism contributes to renal failure in the Col4a3 knockout mouse model for Alport Syndrome. There was an eight-fold increase in the cholesterol content in renal cortexes of mice with Alport Syndrome. This was associated with increased glomerular lipid droplets and cholesterol crystals. Treatment of mice with Alport Syndrome with hydroxypropyl-beta-cyclodextrin (HPbetaCD) reduced cholesterol content in the kidneys of mice with Alport Syndrome and protected from the development of albuminuria, renal failure, inflammation and tubulointerstitial fibrosis. Cholesterol efflux and trafficking related genes were primarily affected in mice with Alport Syndrome and were differentially regulated in the kidney cortex and isolated glomeruli. HPbetaCD also protected from proteinuria and mesangial expansion in a second model of non metabolic kidney disease, adriamycin-induced nephropathy. Consistent with our experimental findings, microarray analysis confirmed dysregulation of several lipid-related genes in glomeruli isolated from kidney biopsies of patients with primary FSGS enrolled in the NEPTUNE study. Thus, lipid dysmetabolism occurs in non-metabolic glomerular disorders such as Alport Syndrome and FSGS, and HPbetaCD improves renal function in experimental Alport Syndrome and FSGS. PMID- 30301570 TI - Non-nucleoside reverse transcriptase inhibitors (NNRTIs)-induced Stevens-Johnson syndrome and gynecomastia in an HIV-infected child: A case report. AB - BACKGROUND: Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are antiretroviral drugs often used in the first-line treatment regimen of HIV1 infection worldwide. We report a case of successive gynecomastia and Stevens Johnson syndrome (SJS) respectively induced by efavirenz and nevirapine in a single patient. CASE REPORT: A 16-year-old boy, HIV1-infected since birth, was started on antiretroviral treatment (ART) in August 2015 and was taking a regimen comprising abacavir, lamivudine and efavirenz. In April 2016, when his weight reached 35kg, abacavir was replaced with tenofovir. Bilateral breast enlargement, previously hidden by the patient, was diagnosed two years after the start of ART. History-taking, physical examination and laboratory tests ruled out known causes of gynecomastia, and efavirenz was thus considered the most likely cause. This drug was then withdrawn and replaced with nevirapine in July 2017. Thirty-three days after the patient started nevirapine treatment, a skin rash appeared. Physical examination revealed erythematous macules and flaccid bullae with estimated skin detachment of 10%. There were also conjunctival, buccal and genital lesions. A diagnosis was made of SJS induced by nevirapine. Three months after withdrawal of efavirenz, breast size decreased by 3cm on the left breast and 2cm on the right breast; two months after the SJS, cutaneous sequelae alone persisted, such as diffuse hyperchromic macules. DISCUSSION: Recognition of gynecomastia as a side-effect of efavirenz is important to allow the condition to be treated while it is still potentially reversible. Moreover, when efavirenz is replaced, a protease inhibitor should be preferred to nevirapine. PMID- 30301571 TI - Deep Learning with Microfluidics for Biotechnology. AB - Advances in high-throughput and multiplexed microfluidics have rewarded biotechnology researchers with vast amounts of data but not necessarily the ability to analyze complex data effectively. Over the past few years, deep artificial neural networks (ANNs) leveraging modern graphics processing units (GPUs) have enabled the rapid analysis of structured input data - sequences, images, videos - to predict complex outputs with unprecedented accuracy. While there have been early successes in flow cytometry, for example, the extensive potential of pairing microfluidics (to acquire data) and deep learning (to analyze data) to tackle biotechnology challenges remains largely untapped. Here we provide a roadmap to integrating deep learning and microfluidics in biotechnology laboratories that matches computational architectures to problem types, and provide an outlook on emerging opportunities. PMID- 30301572 TI - Current Bottlenecks and Challenges of the Microalgal Biorefinery. AB - Microalgae are increasingly considered as sources of renewable feedstocks for industrial production, and microalgae production now focuses on the multiproduct microalgal biorefinery. However, such a biorefinery presents several bottlenecks that are mainly associated with downstream processes. This reduced downstream efficiency results from unsolved problems related to the culture strategy for the accumulation of different products - the protein versus lipid dilemma - and the dilute nature of the microalgal culture. We identify new trends and propose promising solutions for realizing microalgal biorefineries at industrial scale. New perspectives and challenges are identified in protein properties and in the integration and cooptimization of culture and downstream processes. PMID- 30301574 TI - Direct Anterior Approach and Perioperative Fracture With a Single-Taper Wedge Femoral Component. AB - BACKGROUND: Despite growing interest in direct anterior approach total hip arthroplasty, perioperative femoral fracture and early aseptic loosening are increasingly recognized complications. Previous research has documented the role of surgeon experience in association with these femoral complications. The purpose of this study was to explore the relationship between femoral component design and early periprosthetic femoral complications. METHODS: This was an extension of previous work with an updated patient cohort of 5090 consecutive direct anterior primary total hip arthroplasties at a single institution with a single-taper, wedge femoral stem comprising 4 variants involving length and geometry: group 1, full-length, standard profile; group 2, full-length, reduced distal profile; group 3, short-length, standard profile; and group 4, short length, reduced distal profile. Records were reviewed retrospectively for the incidence of early postoperative periprosthetic fracture or aseptic loosening and analyzed with regard to patient demographics and femoral stem type. RESULTS: There were 42 (0.83%) periprosthetic femur complications observed in the early postoperative period. Increased age (P < .001) and female gender (P = .023) were significantly associated with incidence of femoral complications in univariate analysis, while age maintained this significant relationship in multivariate analysis (P < .001). There was a trend toward increased complication rate in patients receiving a short stem with full profile taper (1.27%, P = .0539). CONCLUSION: Despite an overall low rate of femoral complications after direct anterior total hip arthroplasty, the risk is increased in elderly patients and females. Furthermore, femoral stem design may portend an elevated risk of these complications. PMID- 30301573 TI - Optimal contrast-enhanced MRI image thresholding for accurate prediction of ventricular tachycardia using ex-vivo high resolution models. AB - Patient specific models created from contrast-enhanced (i.e. late-gadolinium, LGE) MRI images can be used for prediction of reentry location and clinical ablation planning. However, there is still a need for direct and systematic comparison between characteristics of ventricular tachycardia (VT) morphologies predicted in computational models and those acquired in clinical or experimental protocols. In this study, we aimed to: 1) assess the differences in VT morphologies predicted by modeling and recorded in experiments in terms of patterns and location of reentries, earliest and latest activation sites, and cycle lengths; and 2) define the optimal range of infarct tissue threshold values which provide best match between simulation and experimental results. To achieve these goals, we utilized LGE-MRI images from 4 swine hearts with inducible monomorphic VT. The images were segmented to identify non-infarcted myocardium, semi viable gray zone (GZ), and core scar based on pixel intensity. Several models were reconstructed from each LGE-MRI scan, with voxels of intensity between that of non-infarcted myocardium and 20-50% of the maximum intensity (in 10% increments) in the infarct region classified as GZ. VT induction was simulated in each model. Our simulation results showed that using GZ intensity thresholds of 20% or 30% resulted in the best match of simulated propagation patterns and reentry locations with those from the experiment. Overall, we matched 70% (7/10) morphologies for all the hearts. Our simulation shows that MRI based computational models of hearts with myocardial infarction can accurately reproduce the majority of experimentally recorded post-infarction VTs. PMID- 30301575 TI - An Innovative Ultrasound Strain Elastographic Method for the Differential Diagnosis of Breast Tumors. AB - In this monocentric perspective study examining 64 lesions (19 benign and 45 malignant), we tested an innovative ultrasound elastographic method for diagnosing breast tumors. A new region of control and a new index designating the strain ratio (SR) were used. A traditional ultrasound elastographic method was used as the control. The results indicated that the SR ratios of the benign and malignant groups were 0.25 +/- 0.22 and 1.10 +/- 1.53, respectively, and this difference was statistically significant. The area under the receiver operating characteristic curve of the SR ratio method was 0.95, the cutoff point was 0.37 and the sensitivity and specificity were 95.56% and 94.74%, respectively. The two receiver operating characteristic curves of the traditional method and the SR of the proposed method were significantly different, at a p value of 0.02. Compared with that of the traditional method, the SR obtained with the new method had a larger area under the receiver operating characteristic curve, sensitivity, specificity and objectivity. PMID- 30301576 TI - Mutation analysis of KIF5A in Chinese amyotrophic lateral sclerosis patients. AB - Amyotrophic lateral sclerosis (ALS) is an age-related fatal neurodegenerative orphan disorder that is characterized by progressive injury of both the upper and lower motor neurons. Recently, loss-of-function mutations predominately disrupting the C-terminal amino acid sequence of KIF5A via aberrant exon 27 splicing have been reported in European ALS cohorts. However, the contributions of KIF5A mutations in Asian patients with ALS remain unclear. KIF5A sequences, including exons 26 and 27, were analyzed in a large Chinese ALS cohort comprising 33 unrelated familial ALS probands, 645 sporadic ALS (SALS) patients, 15 ALS patients presenting with concomitant frontotemporal dementia, 400 in-house controls, and 12,951 East Asian individuals from the Exome Aggregation Consortium and Genome Aggregation Database databases. As a result, the previously reported canonical splicing site mutation c.2993-1G>A was found in 1 SALS patient, while no mutations were detected in familial ALS case or ALS patients presenting with concomitant frontotemporal dementia. The frequency of KIF5A mutations accounts for 0.16% (1/645) of Chinese SALS patients, implying that it is an uncommon genetic determinant of ALS in Chinese patients. PMID- 30301577 TI - Productive activities of the older people in Vietnam. AB - Productive activities are crucial factors leading to an "active aging" population. With the case of Vietnam, this paper aimed to explore the productive activities among Vietnamese older people by using data from the Vietnam Aging Survey (VNAS), which was conducted in 2011 as the first-ever nationally representative survey on persons aged 50 and over in Vietnam and contained 2789 older people (those aged 60 and over) representing all older people living in 6 ecological regions and urban and rural areas in Vietnam. Productive activities included working and/or taking care of any (great)grandchild(ren) in the past 12 months prior to the survey. Using paired t-tests and probit models, we compared the differences in these productive activities among older people in terms of sex and living area. The results from various t-tests showed that educational attainment, health status and poverty status were key factors differentiating older men and women and rural and urban older people in these productive activities. For the probit estimations in terms of both gender and living location, the results indicated that age, education, health status and supportive children were determinants of working decision, while age, marital status and size of household were consistently important factors of taking care of (great)grandchildren. The paper also discussed policy implications for socio economic and health protection in promoting older people's productive activities as well as protecting them from a variety of risks and vulnerabilities. PMID- 30301578 TI - Cross-cultural Adaptation and Validation of the Greek Voice Handicap Index-10 (GVHI-10) With Additional Receiver Operating Characteristic Analysis. AB - OBJECTIVE(S): The use of subjective evaluation tools are proven useful and of high clinical value in the case of voice disordered population. For that type of evaluation, self-assessment questionnaires about the severity of the voice like Voice Handicap Index-30 (VHI-30) have been developed. The VHI-30 is the most studied tool which includes psychometrically robustness while guiding physician's therapeutic decision making. Additionally, a valid abbreviated version of VHI-30 was developed for the first time in the Greek Language which is named as Greek Voice Handicap Index-10 (GVHI-10). Consequently, the aim of our study was to validate the proposed version of the VHI-10. METHODS: Ninety nondysphonic individuals and 90 dysphonic patients were classified by Otolaryngologists and Speech Language Pathologists. The study's subjects were evaluated with endoscopy and stroboscopy. Also, they were administrated the GVHI-30 and the translated version of the Voice Evaluation Template (VEF). The GVHI-10 was extracted by the Greek version of VHI-30. RESULTS: The group with voice disorders exhibited higher statistical significance in all GVHI-10 scores compared to those of the control group. The GVHI-10 showed a high internal consistency (Cronbach's a = 0.915 and split-half reliability coefficient equal to 0.86), good sensitivity compared to Greek VHI-30 (r = 0.764, P = 0.000) and intraclass correlation. A total cut-off point equal to 6.50 (AUC: 0.964; P < 0.001) was also calculated. CONCLUSIONS: The proposed version of GVHI-10 distinguished the perceived levels of voice between dysphonic and nondysphonic groups and between different voice disordered populations. The GVHI-10 is shown to be clinically valid and sensitive exhibiting high reliability. PMID- 30301579 TI - Epigenome-wide association study of peripheral blood mononuclear cells in systemic lupus erythematosus: Identifying DNA methylation signatures associated with interferon-related genes based on ethnicity and SLEDAI. AB - Systemic lupus erythematosus (SLE or lupus) is a heterogeneous autoimmune disease characterized by the involvement of multiple organs and the production of antinuclear antibodies. DNA methylation plays an important role in the pathogenesis of lupus. We have performed an epigenome-wide DNA methylation study in lupus and healthy control (non-lupus) subjects to identify epigenetic patterns in lupus characterized ethnicity and SLE disease activity index (SLEDAI). A total of fifty-seven lupus patients (39 African American (AA) and 18 European American (EA)) and 33 healthy controls (17 AA and 16 EA) were studied. Differential DNA methylation between lupus patients and controls was assessed for approximately 485,000 CpG sites across the genome. We identified 41 differentially methylated sites (associated with 30 genes) between lupus and control s subjects, 85% of which were hypomethylated. Significant hypomethylation of differentially methylated sites was associated with several interferon-related genes, including MX1, IFI44L, PARP9, DT3XL, IFIT1, IFI44, RSAD2, PLSCR1, and IRF7. Several of these associated genes were also hypomethylated in comparisons between AA lupus and AA non-lupus subjects and between lupus patients with SLEDAI>6 and non-lupus subjects. Our analysis of gene expression data through RT-PCR confirmed these findings. Thus, the results indicate epigenetics susceptibility in lupus, which may be associated with SLEDAI score and ethnicity. In addition, our findings support the importance of the Type 1 interferon pathway in lupus pathogenesis. PMID- 30301580 TI - Quality gaps and priorities for improvement of healthcare service for patients with prolonged mechanical ventilation in the view of family. AB - BACKGROUND: Little is known about the gaps between expectation and the perception of service quality in the care setting of prolonged mechanical ventilation (MV). METHODS: We conducted this prospective study at the Respiratory Care Center (RCC) of a medical center from February 2017 to January 2018. Family members of the patients admitted to the RCC completed a questionnaire based on the SERVQUAL instrument in two sections - expectation and perception, consisting of 22 questions each in five dimensions. We analyzed the gaps between paired items, used important-performance analysis (IPA) to identify priority items for improvement, and performed multivariate logistic regression analysis. RESULTS: A total of 167 respondents participated in the survey. The average length of patient stay in the RCC was 19.4 days, and 70.7% were successfully liberated from MV. The overall mean SERVQUAL scores for the two sections were similar (4.50 +/- 0.52 and 4.51 +/- 0.54 for expectation and perception, respectively; p = 0.808). IPA identified four items, including one "tangible," one "reliability" and two "empathy" with an undesired expectation/perception gap indicating a priority for improvement. Multivariate logistic regression analysis showed that male respondents, patients older than 75 years, tracheostomy, and the need for physical training or dialysis were associated with an increased gap in these priority items. CONCLUSION: Gaps exist between expectation and perception in multiple dimensions of the quality of healthcare service in the care setting of prolonged MV, indicating unmet needs and priorities for improvement.

PMID- 30301582 TI - Perspectives on window of opportunity trials in head and neck cancer: lessons from the EORTC 90111-24111-NOCI-HNCG study. AB - Assessing tumour response using a traditional phase I, II and III trial approach is not without limitations, particularly when targeted therapies are involved. Window of opportunity trials, performed presurgically but differing from neoadjuvant studies, were developed in an attempt to overcome the limitations of the traditional approach. A recent window of opportunity trial, the EORTC 90111 24111-NOCI-HNCG study, evaluated afatinib in treatment-naive patients with squamous cell carcinoma of the head and neck. While this study was the first to demonstrate the activity of afatinib in this setting and to define its potential predictive biomarkers, it also highlighted the challenges associated with the window of opportunity trial design, including the impact of patient selection, tumour site, and other organisational issues. This report details the key learnings from the EORTC 90111-24111-NOCI-HNCG study and provides recommendations to overcome the challenges of this particular trial design.

PMID- 30301584 TI - Emergency Medical Services Utilization and Outcomes of Patients with ST-Elevation Myocardial Infarction in Lebanon. AB - BACKGROUND: Arrival of patients with ST-elevation myocardial infarction (STEMI) by Emergency Medical Services (EMS) results in shorter reperfusion times and lower mortality in developed countries. OBJECTIVES: This study examines EMS use by STEMI patients in Lebanon and associated clinical outcomes. METHODS: A retrospective observational study with chart review was carried out for STEMI patients arriving to the Emergency Department of a tertiary care center in Lebanon between January 1, 2013 and August 31, 2016. A descriptive analysis was done and followed by a bivariate analysis comparing two groups of patients (EMS vs. Non-EMS). RESULTS: A total of 280 patients were included in the study. They were mostly male (71.8%). Mean age was 65.1 years (95% confidence interval [CI] 63.4-66.9). Only 12.5% (95% CI 8.6-16.4) presented by EMS. Chest pain (81.1%) was the most common presenting symptom. Anterior myocardial infarction was the most common electrocardiogram (ECG) diagnosis (51.4%). Most patients were admitted (98.2%), and 72.0% of these patients were treated with primary percutaneous coronary intervention. Cardiogenic shock was the most frequent in-hospital complication (6.2%). The mortality rate was 7.1%. Mean door-to-ECG and door-to balloon times were 10.8 (95% CI 7.1-14.4) min and 106.2 (95% CI 95.9-116.6) min, respectively. Patients' characteristics, presenting symptoms, outcomes, and performance metrics were similar between the two groups. CONCLUSION: EMS is underutilized by STEMI patients in Lebanon and is not associated with improvement in clinical outcomes. Medical oversight and quality initiatives focusing on outcomes of patients with timely sensitive emergencies are needed to advance the prehospital care system in Lebanon. PMID- 30301585 TI - A Cost-Effective, Rapidly Constructed Simulation Model for Ultrasound-Guided Pericardiocentesis Procedural Training. AB - BACKGROUND: Emergent ultrasound-guided pericardiocentesis (USGP) is an uncommonly performed procedure by emergency physicians (EPs). USGP simulation models have previously been developed to increase procedural proficiency, but these models are limited for routine implementation secondary to high-cost, lengthy time to construct, and lack of durability. The objective of this study was to develop an USGP simulation model that is cost-effective, easily and rapidly constructed, and has procedure-specific fidelity. DISCUSSION: We have developed a novel tofu simulation model for USGP training. The model cost per unit was $1.81 and the average construction time was 2.5 +/- 0.3 min. The model can withstand upward of 100 needle punctures. Our model provides USGP procedure-specific aspiration of a simulated pericardial effusion. CONCLUSIONS: The tofu USGP model provides a cost effective and rapidly constructible simulation tool that could be readily integrated in EP procedural training. PMID- 30301586 TI - [A sternal mass]. PMID- 30301587 TI - The effect of a multidisciplinary approach on geriatric hip fractures in Japan. AB - BACKGROUND: This study aimed to report results of the multidisciplinary treatment approach for geriatric hip fractures and evaluate its effectiveness compared with conventional treatment. Patients aged 65 years and older who presented with a hip fracture at our hospital on or after 2014 were treated according to a multidisciplinary approach. METHOD: Two groups of patients with hip fracture were compared. Group I (n = 364) was treated according to the new multidisciplinary approach in 2014-2016, and Group II (n = 105) which received conventional treatment in 2012. Time to surgery, length of hospital stay, postoperative complications, osteoporosis treatment, functional recovery, in-hospital mortality, 90-day mortality, and 1-year mortality were evaluated. The medical costs of multidisciplinary treatment were compared with those in other hospitals every year. RESULTS: There were no significant differences in the time to surgery between Group I and Group II, but each was considerably shorter than the average time in other Japanese hospitals. The length of hospital stay was longer in Group I. The overall postoperative complication rate was lower in Group I, but there was no significant difference for each individual complication. The rate of anti osteoporosis pharmacotherapy administration at the time of discharge was significantly higher in Group I. Moreover, the proportion of patients who recovered to their pre-injury functional level was significantly higher in Group I. The mortality rates did not significantly differ year on year. The total hospitalization medical cost per patient for the multidisciplinary treatment was lower than other hospital costs every year. CONCLUSIONS: Multidisciplinary treatment produced no significant improvement in time to surgery, length of hospital stay, or postoperative complications. However, the use of the multidisciplinary treatment approach led to a significant increase in osteoporosis treatment rate and better functional recovery. Furthermore, the total medical costs for multidisciplinary treatment were lower than the acute care hospital costs. PMID- 30301588 TI - Nerve Transfers for Enterovirus D68-Associated Acute Flaccid Myelitis: A Case Series. AB - BACKGROUND: Acute flaccid myelitis is associated with enterovirus D68 -induced inflammation and destruction of cervical anterior horn cells. To date, no medical intervention has altered the disease course. METHODS: We report two pediatric patients who were treated with nerve transfer in three limbs with sustained upper extremity neuropathy. Postoperative outcomes included muscle strength, graded on the British Medical Research Council (BMRC) scale, range of motion, and electromyography. RESULTS: Two years postoperatively, Patient 1 had improved elbow flexion to BMRC grade 4+, 125 degrees of flexion, and discrete to decreased motor unit recruitment in targeted muscles. Twenty-one months postoperatively, Patient 2 demonstrated right brachialis flexion to BMRC grade 4+/5 and deltoid firing with simultaneous pectoralis major recruitment, and limited but active flexor digitorum profundus flexion. CONCLUSIONS: Both patients continue to demonstrate functional recovery two years postoperatively. These outcomes suggest a promising reconstructive technique for this emerging and devastating viral endemic. PMID- 30301589 TI - Combining visual sensory functions and visuospatial orienting functions in children with visual pathology: A longitudinal study. AB - BACKGROUND: Peripheral and central visual processing development highly depends on the integrity of the visual sensory system and the allocation of visuospatial attention. METHOD: We quantitatively followed visual sensory functions (VSF) and visuospatial orienting functions (VOF) over two years in 77 children (1-13 years) with different types of visual pathology. RESULTS: Within the clinical groups, VSF were relatively constant over two years, except visual acuity, and VOF were characterized by longer reaction time, shorter fixation duration, and lower fixation accuracy than normal for their age. Children with peripheral pathology had high rates of abnormal VSF, of changes to abnormal visual acuity at 1-6 years, and larger and more abnormal VOF (fixation inaccuracy). Children with central pathology had relatively good VSF, whereas two-third had delayed orienting reaction times that differed from other groups mainly at 1-6 years. CONCLUSION: The distinct patterns of quantitative VSF and VOF over time between the visual pathology groups, and the finding that both methods provided complementary information, argues for combining both types of assessments to provide comprehensive monitoring of visual functioning in children from a young age. PMID- 30301590 TI - Genetic analysis of undiagnosed ataxia-telangiectasia-like disorders. AB - OBJECTIVES: Defects in DNA damage responses or repair mechanisms cause numerous rare inherited diseases, referred to as "DNA-repair defects" or "DNA damage deficiency", characterized by neurodegeneration, immunodeficiency, and/or cancer predisposition. Early accurate diagnosis is important for informing appropriate clinical management; however, diagnosis is frequently challenging and can be delayed, due to phenotypic heterogeneity. Comprehensive genomic analysis could overcome this disadvantage. The objectives of this study were to determine the prevalence of ataxia-telangiectasia (A-T) and A-T-like DNA-repair defects in Japan and to determine the utility of comprehensive genetic testing of presumptively diagnosed patients in facilitating early diagnosis. METHODS: A nationwide survey of diseases presumably caused by DNA-repair defects, including A-T, was performed. Additionally, comprehensive next-generation sequencing (NGS) analysis, targeting known disease-causing genes, was conducted. RESULTS: Sixty three patients with A-T or other diseases with characteristics of DNA-repair defects were identified. Thirty-four patients were genetically or clinically definitively diagnosed with A-T (n = 22) or other DNA-repair defects (n = 12). Genetic analysis of 17 presumptively diagnosed patients revealed one case of ataxia with oculomotor apraxia type 1 (AOA1); one ataxia with oculomotor apraxia type 2 (AOA2); two types of autosomal dominant spinocerebellar ataxia (SCA5, SCA29); two CACNA1A-related ataxias; one microcephaly with or without chorioretinopathy, lymphedema, or mental retardation (MCLMR); and one autosomal dominant KIF1A-related disorder with intellectual deficit, cerebellar atrophy, spastic paraparesis, and optic nerve atrophy. The diagnostic yield was 58.8%. CONCLUSION: Comprehensive genetic analysis of targeted known disease-causing genes by NGS is a powerful diagnostic tool for subjects with indistinguishable neurological phenotypes resembling DNA-repair defects.

AB - AIMS: Charcot foot is a rare but disabling complication to diabetic neuropathy, and can cause permanent, limb-threatening deformities. The aim of this study was to investigate a population of patients a Charcot foot on a case-by-case basis, in order to assess the consequences of an acute Charcot foot and its complications. METHODS: The study was conducted a retrospective study of patients admitted to the Copenhagen Wound Healing Center between 1996 and 2015 with the diagnosis of Charcot foot (DM14.6) and diabetes mellitus type 1 or 2 (DE10.X and DE11.X). Physical and electronic records were used, and compared to data from the Danish Diabetes Registry. RESULTS: In total 392 patients were identified of which 173 were included. There were 26% with type 1 diabetes (initial HbA1c 81.7 +/- 21.4 mmol/mol) and 74% with type 2 diabetes (initial HbA1c 66.5 +/- 20.3 mmol/mol). Primary off-loading was with a removable walker in 95% of the cases (average off-loading time 8.3 months). The 5-year mortality was 14% with a mean survival time of 12.7 years. There was an association between lack of compliance and occurrence of foot complications, as well as between having a Charcot foot and leaving the workforce. CONCLUSION: More patients had type 1 diabetes compared to the background population, and they had a higher HbA1c than the general population of diabetes patients. A total of 67% developed complications such as ulcers, while patients non-compliant to treatment did significantly worse than those being compliant. The 5-year mortality was low, 14%, and comparable to diabetes patients without Charcot foot. PMID- 30301594 TI - Real life evidence that impaired awareness of hypoglycemia persists for years in patients with type 1 diabetes. AB - AIMS: To determine if impaired awareness of hypoglycemia in patients with type 1 diabetes persists over time and to assess if continuous glucose monitoring use was associated with improved awareness of hypoglycemia in our population. METHODS: Thirty-six with type 1 diabetes and impaired awareness of hypoglycemia who participated in studies on impaired awareness of hypoglycemia between 2009 and 2015 were contacted to complete an online survey. The survey included the Cox/Clarke and Gold hypoglycemia questionnaires and questions about continuous glucose monitoring use. RESULTS: 23 of 36 (63%) subjects contacted completed the survey. (12 M, 11 F; median age 51 years, median diabetes duration 34 years). One had had an islet cell transplant and was excluded. Persistent impaired awareness of hypoglycemia was found in 19/22 (86%) using the Cox questionnaire and 18/22 (82%) using the Gold questionnaire. Consistent use of continuous glucose monitoring over the last six months defined as using a device >=75% of time over the last 6 months was reported by 67% (12/18) and 68% (13/19) of participants with persistent impaired awareness of hypoglycemia as measured by Gold and Cox; respectively. Nineteen of the 22 participants (86%) reported severe hypoglycemia over the last six months. CONCLUSION: Impaired awareness of hypoglycemia persisted in >80% of the subjects with type 1 diabetes we studied between 2009 and 2015. While the consistent use of continuous glucose monitoring among our participants was high; it did not translate into restoration of hypoglycemia awareness in this population. This real world data shows that severe hypoglycemia continues to be a frequent problem in this patient population. PMID- 30301595 TI - Cardiovascular effects of caffeinated beverages. AB - Caffeine is the world's most popular 'drug', with tea and coffee a ubiquitous part of daily life. As a psychoactive stimulant, there are potential concerns regarding adverse cardiovascular squeal. Cardiovascular conditions, encompassing hypertension, coronary artery disease, rhythm disorders and heart failure affect billions of patients worldwide. We aim to provide a patient-centered comprehensive review of the cardiovascular effects of caffeinated beverages as they pertain to various common cardiovascular conditions. We conclude that intake of tea and coffee, particularly in moderate doses, does not appear to be harmful and may even be beneficial in a range of cardiovascular conditions, including coronary artery disease, heart failure and arrhythmias. PMID- 30301592 TI - Vector Immunity and Evolutionary Ecology: The Harmonious Dissonance. AB - Recent scientific breakthroughs have significantly expanded our understanding of arthropod vector immunity. Insights in the laboratory have demonstrated how the immune system provides resistance to infection, and in what manner innate defenses protect against a microbial assault. Less understood, however, is the effect of biotic and abiotic factors on microbial-vector interactions and the impact of the immune system on arthropod populations in nature. Furthermore, the influence of genetic plasticity on the immune response against vector-borne pathogens remains mostly elusive. Herein, we discuss evolutionary forces that shape arthropod vector immunity. We focus on resistance, pathogenicity and tolerance to infection. We posit that novel scientific paradigms should emerge when molecular immunologists and evolutionary ecologists work together. PMID- 30301596 TI - Left Atrial or Left Atrial Appendage Thrombus Resolution After Adjustment of Oral Anticoagulant Treatment. AB - BACKGROUND: There are few reports about non-vitamin K antagonist oral anticoagulant (NOAC) treatment for resolution of left atrium (LA) or left atrial appendage (LAA) thrombus. LAA thrombus is an important cause of cardiogenic cerebral thromboembolism, and the detection rate increases due to more and more patients receiving catheter ablation. However, the results from NOAC use for LA or LAA thrombus are still unknown in real-world practice. The aim of this study was to discover the resolution of LA or LAA thrombus after anticoagulant treatment in real-world practice. METHOD: From January 2013 to December 2016, a total 864 patients underwent transesophageal echocardiography (TEE), and 41 cases of LA or LAA thrombus were detected in our hospital. Among them, a total of 22 patients underwent follow-up TEE to detect the resolution of LA or LAA thrombus. RESULT: The average age of the study patients was 72.0 +/- 11years old, and 61% were male. The average CHA2DS2-VASc scores were 3.76 +/- 2.01 points. A total of 22 patients underwent follow-up TEE, and 19 (86.4%) patients presented LA or LAA thrombus resolution. The average resolution duration was 258.47 +/- 218.17days. One-year all-cause mortality was 4.9%, and the incidence of ischemic stroke was 4.9%. Most physicians favored titration of the dosage of NOAC or warfarin in real world practice. CONCLUSION: In real-world practice, most physicians favored titration of the dosage of NOAC or warfarin for LA or LAA thrombus. LA or LAA thrombus could exist if the patient received a reduced dose of NOAC. High frequency of LAA or LA thrombi could resolve, and a low incidence of ischemic stroke occurred after adjustment of oral anticoagulant treatment. PMID- 30301597 TI - Effects of irradiation with narrowband-ultraviolet B on up-regulation of histamine H1 receptor mRNA and induction of apoptosis in HeLa cells and nasal mucosa of rats. AB - Narrowband-ultraviolet B (NB-UVB) phototherapy is used for the treatment of atopic dermatitis. Previously, we reported that irradiation with 200 mJ/cm2 of 310 nm NB-UVB suppressed phorbol-12-myristate-13-acetate (PMA)-induced up regulation of histamine H1 receptor (H1R) gene expression without induction of apoptosis in HeLa cells. However, the effect of NB-UVB irradiation on nasal symptoms is still unclear. Here, we show that low dose irradiation with 310 nm NB UVB alleviates nasal symptoms in toluene 2,4-diisocyanate (TDI)-sensitized allergy model rats. Irradiation with 310 nm NB-UVB suppressed PMA-induced H1R mRNA up-regulation in HeLa cells dose-dependently at doses of 75-200 mJ/cm2 and reversibly at a dose of 150 mJ/cm2 without induction of apoptosis. While, at doses of more than 200 mJ/cm2, irradiation with 310 nm NB-UVB induced apoptosis. Western blot analysis showed that the suppressive effect of NB-UVB irradiation on H1R gene expression was through the inhibition of ERK phosphorylation. In TDI sensitized rat, intranasal irradiation with 310 nm NB-UVB at an estimated dose of 100 mJ/cm2 once a day for three days suppressed TDI-induced sneezes and up regulation of H1R mRNA in nasal mucosa without induction of apoptosis. These findings suggest that repeated intranasal irradiation with low dose of NB-UVB could be clinically used as phototherapy of AR. PMID- 30301598 TI - Inflammation in human adipose tissues-Shades of gray, rather than white and brown. AB - Chronic inflammation in adipose tissues has been associated with obesity and metabolic syndrome over the years. Various studies using animal models have contributed to our knowledge on the pro- and anti- inflammatory mediators that regulate obesity. Analyses of cytokine profiles in humans have not revealed a clear scenario. Likewise, treatments targeting inflammation to control obesity and insulin resistance has not yielded promising results. In this review we summarize the data available in human obesity and discuss the possible reasons that could explain the difficulties in treating obesity and insulin resistance by targeting pro-inflammatory cytokines. PMID- 30301599 TI - Cervical cancer cells produce TGF-beta1 through the CD73-adenosine pathway and maintain CD73 expression through the autocrine activity of TGF-beta1. AB - In cancer, the adenosinergic pathway participates in the generation of an immunosuppressive microenvironment and in the promotion of tumor growth through the generation of adenosine (Ado). The present study analyzed the participation of Ado, generated through the functional activity of the cervical cancer (CeCa) pathway in CeCa cells, to induce the expression and secretion of TGF-beta1, as well as the participation of this factor to maintain CD73 expression. Ado concentrations greater than 10 MUM were necessary to induce an increase of over 50% in the production and expression of TGF-beta1 in CeCa tumor cells. Blockade of A2AR and A2BR with the specific antagonists, ZM241385 and MRS1754, respectively, strongly reversed the production of TGF-beta1. TGF-beta1 produced by CeCa cells was necessary to maintain CD73 expression because the addition of anti-TGF-beta neutralizing antibodies or the inhibition of TGF-betaRI strongly reversed the expression of CD73 in the CeCa cells. These results suggested a feedback loop in CeCa cells that favors immunosuppressive activity through the production of TGF-beta1 and Ado as well as the autocrine activity of TGF-beta1 and expression of CD73. PMID- 30301600 TI - A newly generated neuronal cell model of CLN7 disease reveals aberrant lysosome motility and impaired cell survival. AB - Mutations in the CLN7/MFSD8 gene encoding the lysosomal membrane protein CLN7 are causative of CLN7 disease, an inherited neurodegenerative disorder that typically affects children. To gain insight into the pathomechanisms of CLN7 disease, we established an immortalized cell line based on cerebellar (Cb) granule neuron precursors isolated from Cln7-/- mice. Here, we demonstrate that Cln7-deficient neuron-derived Cb cells display an abnormal phenotype that includes increased size and defective outward movement of late endosomes and lysosomes as well as impaired lysosomal exocytosis. Whereas Cln7-/- Cb cells appeared to be autophagy competent, loss of Cln7 resulted in enhanced cell death under prolonged nutrient deprivation. Furthermore, reduced cell survival of Cln7-deficient cells was accompanied by a significantly impaired protein kinase B/Akt phosphorylation at Ser473 during long-term starvation. In summary, our data demonstrate for the first time that the putative lysosomal transporter CLN7 is relevant for lysosome motility and plays an important role for neuronal cell survival under conditions of starvation. PMID- 30301601 TI - Fruit and Vegetable Preferences and Practices May Hinder Participation in Community-Supported Agriculture Among Low-Income Rural Families. AB - OBJECTIVE: Describe fruit and vegetable (FV) preferences and other factors that may influence participation in community-supported agriculture (CSA). DESIGN: In depth, semi-structured interviews. SETTING: Eight rural/micropolitan communities in 4 US states. PARTICIPANTS: There were 41 caregivers and 20 children (8-12years of age) from low-income, English-speaking households. PHENOMENA OF INTEREST: Knowledge, attitudes, and behaviors regarding FVs; perceived barriers to CSA participation. ANALYSIS: Transcribed verbatim and iteratively coded. RESULTS: Caregivers and children believed FVs were important to health, yet FVs were not featured in dinners or snacks and consumption was challenged by limited preferences and neophobia. Few caregivers and children knew about the seasonality of FV. Most caregivers were unfamiliar with CSA and had concerns about CSA cost, accessibility, produce quality, and selection. CONCLUSIONS AND IMPLICATIONS: These qualitative data support improvements in: 1) CSA distribution practices to offer flexible payment and pick-up options, more fruits, and self-selection of FV; 2) public awareness of produce seasonality and the CSA distribution model as necessary precursors to participation, and lower cost for low-income families who highlighted this barrier; and 3) capacity to prepare FV by enhancing skills and providing time-saving kitchen tools. Approaches to aligning CSA practices with the needs and preferences of low-income families warrant further research. PMID- 30301602 TI - Preoperative anemia and extensive transfusion during stay-in-hospital are critical for patient's mortality: A retrospective multicenter cohort study of oncological patients undergoing radical cystectomy. AB - BACKGROUND: Preoperative anemia and allogeneic blood transfusions (ABTs) may affect outcomes in cancer surgery. The prevalence of anemia, the use of ABTs, the risks of transfusions, lengths of stay and mortality of oncological patients undergoing radical cystectomy were investigated in three University Hospitals in Germany. PATIENTS AND METHODS: Hospital records of 220 consecutive patients undergoing radical cystectomy from 2010 to 2012 were retrospectively analyzed for independent risk factors of ABT and unfavorable outcomes (readmission, increased length of stay (LOS) or death) using multivariate regression analysis. RESULTS: Preoperative anemia was present in 40%. 70% of patients received blood transfusions. Low preoperative and intraoperative nadir hemoglobin levels were associated with receipt of ABT (OR 1.33, P = 0.04 and OR 2.94, P < 0.001 respectively). Transfusion of ten or more red blood cell units (RBCs) during the entire hospital stay was a predictor of an increased LOS (P < 0.001) and death (OR 52, 95%CI [5.9, 461.3], P < 0.001), compared to non-transfused patients. Preoperative ABT and ASA scores were associated with >=10RBCs. CONCLUSION: Anemic patients undergoing radical cystectomy had a high risk to receive ABTs. Preoperative transfusions and transfusion of >=10RBCs during the entire hospital stay may increase patient's mortality. Prospective, randomized controlled studies have to follow this study. PMID- 30301604 TI - Focus on pancreatic cancer. PMID- 30301603 TI - Sec23a mediates miR-200c augmented oligometastatic to polymetastatic progression. AB - BACKGROUND: Cancer treatment is based on tumor staging. Curative intent is only applied to localized tumors. Recent studies show that oligometastatic patients who have limited number of metastases may benefit from metastasis-directed local treatments to achieve long-term survival. However, mechanisms underlying oligometastatic to polymetastatic progression remains elusive. METHODS: The effects of miR-200c and Sec23a on tumor metastasis were verified both in vitro and in vivo. The secretome changes were detected by mass spectrometry. FINDINGS: We established a pair of homologous lung-metastasis derived oligometastatic and polymetastatic cell lines from human melanoma cancer cell line M14. Using the two cell lines, we have identified Sec23a, a gene target of miR-200c, suppresses miR 200c augmented oligometastatic to polymetastatic progression via its secretome. Firstly, miR-200c over-expression and Sec23a interference accelerated oligometastatic to polymetatic progression. Secondly, Sec23a functions downstream of miR-200c. Thirdly, mass spectrometric analysis of the secretory protein profile suggests that Sec23a-dependent secretome may impact metastatic colonization by modifying tumor microenvironment. Fourthly, the survival analysis using The Cancer Genome Atlas database shows Sec23a as a favorable prognostic marker for skin cutaneous melanoma, supporting the clinical relevance of our findings. INTERPRETATION: The finding that Sec23a is a suppressor of oligometastatic to polymetastatic progression has clinical implications. First, it provides a new theoretical framework for the development of treatments that prevent oligometastasis to polymetastasis. Second, Sec23a may be used as a favorable prognostic marker for the selection of patients with stable oligometastatic disease for oligometastasis-based local therapies of curative intent.

PMID- 30301606 TI - Ultrasound guidance improves safety and efficiency of central line placements. AB - BACKGROUND: Use of ultrasound-guidance for central venous access in adults is the standard of care. There is, however, less clarity in the role of routine ultrasound use in obtaining venous access in children. We sought to evaluate safety and efficiency of the placement of central lines utilizing an ultrasound guided approach compared to the traditional, landmark approach in pediatric patients. STUDY DESIGN: A single-institution retrospective chart review, using CPT codes, was performed for all tunneled central venous catheters in children between 2005 and 2017 by the same pediatric surgery group. During the study period, a practice change occurred from exclusively landmark-based line placement to ultrasound-guided line placement. Groups were divided into three phases: a traditional/landmark era (Phase 1), transitional period (Phase 2), and the ultrasound era (Phase 3). The primary outcomes analyzed were postoperative chest tube insertions and operative time. RESULTS: A total of 2010 tunneled central lines were included for analysis: Phase 1 (N = 930), Phase 2 (N = 313) and Phase 3 (N = 767). Venous access for chemotherapy was the most common indication (29%). Phase 1 had a chest tube placement rate of 9.7/1000 procedures, while Phase 2 had a rate of 6.4/1000 procedures, and Phase 3 had no chest tube insertions (p = 0.009). Phase 1 had longer OR times compared to Phase 2 (57 vs. 49, p = 0.0026) and Phase 3 (57 vs. 46 min, p < 0.001). CONCLUSIONS: This study represents the largest analysis of ultrasound-guided access for children. A complete practice transition to the ultrasound-guided approach was feasible within a two-year period. The ultrasound-guided approach had a shorter operative time and less chest tube insertions than the traditional, landmark technique in children. Level III evidence. PMID- 30301607 TI - Reimaging in pediatric blunt spleen and liver injury. AB - BACKGROUND: APSA guidelines do not recommend routine reimaging for pediatric blunt liver or spleen injury (BLSI). This study characterizes the symptoms, reimaging, and outcomes associated with a selective reimaging strategy for pediatric BLSI patients. METHODS: A planned secondary analysis of reimaging in a 3-year multi-site prospective study of BLSI patients was completed. Inclusion required successful nonoperative management of CT confirmed BLSI without pancreas or kidney injury and follow up at 14 or 60 days. Patients with re-injury after discharge were excluded. RESULTS: Of 1007 patients with BLSI, 534 (55%) met inclusion criteria (median age: 10.18 [IQR: 6, 14]; 62% male). Abdominal reimaging was performed on 27/534 (6%) patients; 3 of 27 studies prompting hospitalization and/or intervention. Abdominal pain was associated with reimaging, but decreased appetite predicted imaging findings associated with readmission and intervention. CONCLUSION: Selective abdominal reimaging for BLSI was done in 6% of patients, and 11% of studies identified radiologic findings associated with intervention or re-hospitalization. A selective reimaging strategy appears safe, and even reimaging symptomatic patients rarely results in intervention. Reimaging after 14 days did not prompt intervention in any of the 534 patients managed nonoperatively. LEVEL OF EVIDENCE: Level II, Prognosis. PMID- 30301608 TI - Prevalence and natural history of scoliosis and associated congenital vertebral anomalies in patients operated for esophageal atresia with or without tracheoesophageal fistula. AB - BACKGROUND: Scoliosis has been reported after repair of esophageal atresia with or without tracheoesophageal fistula (EA-TEF). This study aims to investigate the prevalence and natural history of scoliosis and associated congenital vertebral anomalies in patients operated for EATEF. METHODS: A retrospective review of patients operated for EA-TEF with radiological examination for the presence of scoliosis or associated spine congenital anomalies was done on 106 patients (ages 5-19 years). RESULTS: Scoliosis was found in 53 patients (49%) for which 46 of these were in the thoracic region and 33 were right-thoracic curves. After a follow-up ranging from 5 to 14 years, four patients (3.7%) out of 106 were operated for scoliosis. Right-sided thoracotomy (RST) was the identifiable risk factor for scoliosis development; all patients with scoliosis had their EA repaired through RST. Congenital vertebral anomalies were found in 8 of those patients (7.5%). After a median follow-up of 6.5 years, no patients progressed enough to require operation. CONCLUSION: Scoliosis affects one of every two patients operated for EA; it may progress to the indication of surgery. RST was the identifiable risk factor for scoliosis development. PMID- 30301609 TI - Tissue expansion in pediatric patients: a 10-year review. AB - BACKGROUND/PURPOSE: Tissue expansion complication rates up to 40% have been reported in the pediatric population. This study aims to review one Canadian pediatric plastic surgeon's experience with tissue expansion by examining tissue expander and flap complication rates, and discussing important aspects of the tissue expansion experience. METHODS: This is a retrospective chart review of the medical records of all tissue expansion patients treated by the senior author during a ten-year period. Data were collected on patient demographics, tissue expansion details, complications, and outcomes, and were analyzed descriptively. The relationship between tissue expander complications and flap complications was analyzed with odds ratio. RESULTS: Ninety-three expanders were placed in 24 patients during 49 sessions. Complications occurred in 19 expanders (10 patients; 16 sessions), resulting in premature removal of nine. Only one session was unsuccessful; the expander became exposed and was removed after 1 month. The odds of having a flap complication were three times greater with preceding tissue expander complication (not statistically significant). CONCLUSIONS: Our study identifies a 20% expander complication rate in the pediatric population. Patients with tissue expander complications subsequently experienced more flap complications than those without tissue expander complications. Complications do not preclude successful reconstruction. TYPE OF STUDY: Prognostic. LEVEL OF EVIDENCE: II.

AB - Post-transplantation lymphoproliferative disorder (PTLD) is a well-know complication after organ transplantation. We report a case of a patient who developed an extramedullary plasmacytoma-like PTLD around his transplanted kidney treated with standard multiple myeloma chemotherapy. Three years after benefiting of a deceased donor kidney transplant for an end stage kidney disease secondary to nephroangiosclerosis, our patient developed an extra-medullary plasmacytoma confined to the transplant compartment. The transplant function was unaltered, and due to the absence of reduction of the lesion after immunosuppression reduction, a chemotherapy by bortezomib-cyclophosphamide-dexamethasone (VCD) known to be efficient in multiple myeloma was initiated. After 6 cycles, positron emission tomography (PET) scan showed complete metabolic remission confirming the biological exams. This case report suggests that a chemotherapy such as VCD can efficiently treat plasmacytoma-like PTLD allowing graft survival. Therefore, transplant removal may not be mandatory as the best second line treatment after unsuccessfulness reduction of immunosuppression. PMID- 30301611 TI - [Non-iodinated contrast media nephrotoxicity]. AB - The development of interventional radiology techniques regularly exposes patients to the potential renal toxocity of iodinated contrast media. Faced with this risk of nephrotoxicity, gadolinium-based contrast agents have long been considered as a safe alternative to iodinated contrast media, especially in sensitive or at risk patients. However, these gadolinium-based contrast agents are not devoid of nephrotoxicity and present another risk, a complication related to renal failure, the nephrogenic systemic fibrosis. European and US recommendations from health agencies have recently come closer, defining groups of patients at risk of nephrogenic systemic fibrosis according to their level of renal function and the type of gadolinium-based contrast agent used. What are the real renal risks for these products? How to evaluate the benefit-risk balance of the patient to choose a radiological examination in an informative, effective and safe way? This article focuses on the description of the risks of gadolinium-based contrast agents, reviews existing recommendations and best practices to guide the choice of clinicians. PMID- 30301612 TI - Reactive oxygen species mediated placental oxidative stress, mitochondrial content, and cell cycle progression through mitogen-activated protein kinases in intrauterine growth restricted pigs. AB - Intrauterine growth restriction (IUGR) remains a significant obstacle in pig production; however, information regarding the relationship between reactive oxygen species (ROS)-induced placental dysfunction and IUGR is still unknown. This study aimed to explore the placental redox status, mitochondrial content, cellular progression, and mitogen-activated protein kinase (MAPK) pathways in IUGR. Placental tissues were collected from normal intrauterine gestation (NIUG) and IUGR fetuses at delivery. Compared with the NIUG, placental ROS production, lipid peroxidation, and DNA damage were increased in IUGR. Placental mitochondrial DNA (mtDNA) content and mtDNA-encoded gene expression decreased in IUGR. Moreover, p21 phosphorylation increased, cyclin E expression decreased in IUGR cases, which showed senescence characteristics. Analysis of signaling pathways showed that the ERK1/2 phosphorylation increased whereas the p38 and JNK phosphorylation decreased in IUGR. In cultured porcine trophectoderm (pTr) cells, exogenous H2O2 increased intracellular ROS production, decreased cell viability in a dose-dependent manner. Cell cycle distribution was found to arrest in S and G2/M phases. Our findings suggested that IUGR was associated with greater placental ROS and oxidative injury, which might be a factor that resulted in lower mitochondrial content, microvilli loss and senescence, and activation of MAPK pathways.

AB - BACKGROUND: A patient's ability to move his/her fingers during hand surgery may be helpful to surgeons because it allows the effectiveness of the intervention evaluation and prediction of hand function in the postoperative period. The purpose of this case series is to demonstrate the efficacy of an ultrasound guided peripheral nerve block technique to maintain the hand flexor and extensor muscles motor function and discuss the benefits of the technique for trigger finger surgery. CASE REPORT: Ten patients scheduled to undergo trigger finger surgery were selected. The goal was to maintain flexion and extension of the fingers during the procedure. Thus, ultrasound-guided ulnar, radial, and medial nerve block was performed in the distal third of the forearm, at 5-7cm proximal to the wrist. The block was performed with 5mL of 0.375% bupivacaine on each nerve. All procedures were uneventfully performed maintaining the flexion and extension of the fingers. In two cases, it was observed that the motricity maintenance and the patients' ability to move their fingers when requested allowed the success of the surgical procedure after the third intraoperative evaluation. CONCLUSION: This case series shows that it is possible to maintain the motor function of the hand flexor and extensor muscles to perform finger trigger surgeries using specific ultrasound-guided distal blocks.

AB - BACKGROUND AND OBJECTIVES: Ultrasound-guided upper limb blocks may provide great benefits to patients with serious diseases. Patients with Steinert's disease have muscle weakness and risk of triggering myotony or malignant hyperthermia due to the use of anesthetic agents and surgical stress. The objective of this report was to demonstrate a viable alternative for clavicle fracture surgery with upper trunk and supraclavicular nerve block, thus reducing the spread of local anesthetic to the phrenic nerve in a patient with muscular dystrophy. CASE REPORT: A 53-year-old male patient with Steinert's disease, associated with dyspnea, hoarseness and dysphagia, referred to the surgical theater for osteosynthesis of clavicle fracture. Upper limb (1mL 0.75% ropivacaine) and supraclavicular nerve block (1mL 0.75% ropivacaine in each branch) were combined with venous anesthesia with propofol under laryngeal mask (infusion pump target of 4 mcg.Ml-1). Upon awakening, the patient had no pain or respiratory complaints. He was transferred to the ICU for immediate postoperative follow-up with discharge from this unit after 24hours without complications. CONCLUSIONS: The superior trunk and cervical plexus block associated with venous anesthesia under laryngeal mask, without the use of opioids, proved to be adequate in the case of a patient with clavicle fracture and Steinert's disease. With the use of ultrasonography in regional anesthesia it is possible to perform increasingly selective blocks, thus allowing greater security for the anesthetic-surgical procedure and lower morbidity for the patient.

AB - INTRODUCTION AND OBJECTIVES: Limited data are available on the clinical outcomes of optimal medical therapy (OMT) compared with revascularization by percutaneous coronary intervention (PCI) in patients with chronic total coronary occlusion (CTO) of the proximal or middle left anterior descending artery (pmLAD). Therefore, the objective of this study was to compare the long-term outcomes of patients with pmLAD CTO who were treated with a PCI strategy with those of patients treated with an OMT strategy. METHODS: Between March 2003 and February 2012, 2024 patients with CTO were enrolled in a single-center registry. Among this patient group, we excluded CTO patients who underwent coronary artery bypass grafting. After the exclusion, a total of 1547 patients remained. They were stratified according to classification of coronary segments (pmLAD or non-pmLAD CTO) and the initial treatment strategy (OMT or PCI). Propensity score matching was performed. The primary outcome was cardiac death. RESULTS: The median follow up was 45.9 (interquartile range, 22.9-71.1) months. After propensity score matching, the incidence of cardiac death (HR, 0.54; 95%C, 0.31-0.94, P=.029) was significantly lower in the PCI with pmLAD CTO group than in the OMT group. In contrast, no significant difference was found in the rate of cardiac death between the PCI and OMT groups with non-pmLAD CTO (HR, 0.62; 95%CI, 0.27-1.42, P=.26). CONCLUSIONS: As an initial treatment strategy, PCI of pmLAD CTO, but not PCI of non-pmLAD, is associated with improved long-term survival.

AB - OBJECTIVE: To compare the effectiveness of an ALTIS(r) mini-sling and a conventionnal suburethral sling TVT-ABBREVO(r) for treatment of female stress urinary incontinence. METHODS: A single-center retrospective study included all female patients fitted with a conventional transobturator tape (TVT-ABBREVO(r)) or mini-sling (ALTIS(r)), during 2015, in Angers university hospital. The success rate was defined by no urine leakage during a cough test on clinical examination, improved quality of life defined by a PGI-I (Patient Global Impression of Improvement) score of 1 to 3, and no stress urinary incontinence on USP (Urinary Symptom Profile) questionnaire. Morbidity associated with slings and perioperative data were also recorded. RESULTS: Ninety-two patients were included (39 in the ALTIS group and 53 in the ABBREVO group). The average follow-up was 13.55 months. The success rate was not significantly different in ALTIS group for the negative cough test (89.7% vs 94.3% in ABBREVO group, P=0.45), for the absence of urinary leakage reported on the USP questionnaire (87.2% vs 90.6% in ABBREVO group, P=0.61), or for the improvement of the quality of life with a PGI I score between 1 and 3 (82.1% vs 86.8% in ABBREVO group, P=0.53). On the other hand, more patients were fully satisfied, with a PGI-I quality of life score of 1, in ABBREVO group than in ALTIS group (67.9% compared with 46.2%, P=0.03). Immediate postoperative pain was significantly less intense in ALTIS group than in ABBREVO group (average VAS score of 0.5 comparated with 1.3, P=0.01), but this difference had disappeared one week after surgery. The rates of other complications were similar in both groups. CONCLUSION: The functional results of the ALTIS and TVT-ABBREVO(r) slings appear similar in the treatment of female stress urinary incontinence. PMID- 30301619 TI - Evaluation of candidate reference genes for investigation of the uterine tissue and corpus luteum of pigs on day 6 after artificial insemination. AB - Housekeeping genes (HKG) are genes necessary for the maintenance of basal cellular functions, regardless of the specific roles within a tissue. It, therefore, is expected that these genes will maintain a relatively constant expression profile when there are varying physiological conditions. The identification of tissue specific reference genes is highly important for the normalization of gene expression profiles among different tissues. In this sow study, the objective was to identify stable reference genes in the uterine tissue and corpus luteum (CL), 6 days post-artificial insemination. The stability of ubiquitin (UBB), glyceraldehyde 3-phosphate dehydrogenase (GAPDH), DNA topoisomerase 2-beta (TOP2B), histone H3 (H3F3A) and hypoxanthine-guanine phosphoribosyltransferase 1 (HPRT1) abundances of mRNA were evaluated using the Bestkeeper technique. Briefly, total RNA was extracted for each tissue from 20 gilts (n = 20), processed by RT-qPCR and submitted to analysis using the Bestkeeper technique, which allowed for the evaluation of the consistency in abundance of mRNA for the reference genes. For all evaluated genes, the abundance of mRNA was relatively consistent in the uterine tissue, with the greatest abundance being for the GAPDH and TOP2B genes. The analysis of these genes in the CL, however, indicated there was a relatively greater variation of mRNA abundance for the various reference genes. Data suggest that UBB was the reference gene with the most consistent relative abundance of mRNA and that this gene could be used as a reference for corpora lutea analyses of mRNA. PMID- 30301620 TI - Effect of length of time post-mortem on quality and freezing capacity of Cantabric chamois (Rupicapra pyrenaica parva) epididymal spermatozoa. AB - Genome Resource Banks are keystones in the ex-situ conservation of wild species. Post-mortem (PM) collection of epididymal spermatozoa is an opportunistic and valuable source of germplasm, the time from the death of the animal limits its use. Seeking to improve germplasm preservation strategies for the chamois (Rupicapra sp.), the effect of PM time on epididymal sperm quality and freezability was studied using the Cantabrian chamois. Samples were classified according to PM collection time, up to 216 h (refrigerated), and cryopreserved (Tris-citric acid-fructose, 430 mOsm/kg, 15% egg yolk, 8% glycerol; freezing at 20 degrees C/min). Sperm quality was assessed after recovery and post-thawing (motility by CASA, HOS test, abnormal forms, cytoplasmic droplets, and viability and acrosomal damage by flow cytometry). The sperm mass pH and osmolality showed a positive correlation with time. Total sperm motility dropped after 2 days PM, with progressivity and sperm velocities remained similar up to 3 days PM. Sperm freezability was acceptable, with the post-thawing HOST, motility, progressivity, VAP, VCL, VSL and BCF negatively correlating with PM time. Overall, chamois epidydimal samples were not adequate for preservation after 6 days PM. Freezability capacity could make these spermatozoa suitable for specific ART even if kept refrigerated for several days PM. PMID- 30301621 TI - Sperm quality in wild-caught and farmed males of the European eel (Anguilla anguilla). AB - Sperm density and performance of wild and farmed male European eels were evaluated to investigate the effect of maintenance in captivity on ejaculate quality. Hormonal stimulation (with human chorionic gonadotropin) lasted for 17 weeks. Different origins of the male European eels partially influenced the quality of the ejaculates. Indeed, wild animals (i.e., collected at a natural site) had greater sperm longevity during the hormonal stimulation, whereas there was no significant effect of the origin on sperm density, spermatocrit, the percentage of motile sperm, and plasma testosterone concentrations. The different origins of the males also affected fatty acid sperm content, with greater unsaturated fatty acid and omega-6 concentrations in wild eels and lesser concentrations of saturated fatty acids and omega-3 fatty acids in farmed eels. Regarding sperm quality of European eels, this is the first study that takes into account the effect of different origins of stimulated males (wild-caught compared with farmed) on sperm quality, and these findings may help to improve the production of high-quality gametes in this endangered species. PMID- 30301622 TI - Effect of reduced glutathione (GSH) supplementation to Tris-egg yolk extender on chilled semen variables of dogs. AB - One reason for reduced longevity of chilled dog semen is oxidative stress. The antioxidant glutathione (GSH) improves viability of frozen-thawed dog sperm, but its effect on chilled dog semen has not been investigated. An experiment consisting of two parts was performed: Sperm rich fractions, SRF, were split, diluted with a Tris-egg yolk (TEY) extender containing 0, 5 or 10 mM GSH and stored at 4 degrees C for 10 days (Part 1; n = 19) or 4 days (Part 2; n = 11), respectively. For Part 1 of the study, percentage (%) of motile, viable, morphologically abnormal spermatozoa and % acrosomal deviations were assessed on days 0, 1, 2, 4 and 10 after dilution. For % sperm motility, samples from all three aliquots of each SRF (0/5/10 mM GSH) were pipetted simultaneously and analysed in a randomised order (time point of analysis, TPA). In Part 2 of the study, motility analysis was performed during 4 days storage and samples were analysed immediately after pipetting (part 2). Most investigated parameters were affected by storage time. For motility variables, there was an effect of GSH identified for circular, CM (ANOVA, Part 1: P = 0.05, Part 2: P < 0.0001) and local motility, LM (ANOVA, Part 2: P = 0.004). Furthermore, there was a trend for an interaction between time and sperm treatment for CM (Part 2: P = 0.077). In conclusion, in the present study there was not an overall positive effect of GSH addition (5/10 mM) on sperm motility in chilled dog semen samples that were characterised to be of good quality during 4- and 10-days of storage. PMID- 30301623 TI - Towards quantitative analysis of enamel erosion by focused ion beam tomography. AB - OBJECTIVES: The purpose of this work is a proof of concept to introduce a new quantitative 3D-analysis of dental erosion obtained by focused ion beam (FIB) tomography associated with silver nitrate penetration into porosities in etched enamel. METHODS: One sample selected was sound enamel after removal of the aprismatic surface. The other was studied after applying an additional attack with orthophosphoric acid. Both surfaces were infiltrated with silver nitrate via immersion. After dehydration, samples were observed in a dual column FIB/SEM station. Serial FIB sectioning was conducted with a current of 3nA at 30keV and an increment step of 20nm for the healthy enamel and of 40nm for the etched one. 3D analysis was performed with Fiji software and BoneJ plugin and several parameters were obtained to characterize the tissue: non-mineralized phase content (NMP), connected porosity fraction (CPF) and degree of anisotropy (DA) of the NMP. RESULTS: Healthy enamel showed an NMP content of 0.5vol.%, with a bimodal distribution of non-mineralized regions, inside the prisms and between the prisms. No silver penetration was noticed in the healthy enamel, demonstrating the absence of open porosity. In contrast, silver nitrate penetration after acidic exposure was observed, up to a depth of 12MUm, which allowed the calculation of an interconnected porosity volume fraction (CPF) of 3.1vol.%, mostly between the prisms. Values for DA of 0.56 for sound enamel and 0.81 for acid-etched surface were determined, highlighting a higher degree of anisotropy in the latter. SIGNIFICANCE: Quantitative analysis of FIB tomography using NMP, CPF and DA should contribute to a better understanding and follow up of dental erosion, correlation between erosion and attrition or abrasion process, and the ability to develop enamel remineralization procedures. PMID- 30301624 TI - Biostable, antidegradative and antimicrobial restorative systems based on host biomaterials and microbial interactions. AB - OBJECTIVES: Despite decades of development and their status as the restorative material of choice for dentists, resin composite restoratives and adhesives exhibit a number of shortcomings that limit their long-term survival in the oral cavity. Herein we review past and current work to understand these challenges and approaches to improve dental materials and extend restoration service life. METHODS: Peer-reviewed work from a number of researchers as well as our own are summarized and analyzed. We also include yet-unpublished work of our own. Challenges to dental materials, methods to assess new materials, and recent material improvements and research directions are presented. RESULTS: Mechanical stress, host- and bacterial-biodegradation, and secondary caries formation all contribute to restoration failure. In particular, several host- and bacterial derived enzymes degrade the resin and collagen components of the hybrid layer, expanding the marginal gap and increasing access to bacteria and saliva. Furthermore, the virulence of cariogenic bacteria is up-regulated by resin biodegradation by-products, creating a positive feedback loop that increases biodegradation. These factors work synergistically to degrade the restoration margin, leading to secondary caries and restoration failure. Significant progress has been made to produce hydrolytically stable resins to resist biodegradation, as well as antimicrobial materials to reduce bacterial load around the restoration. Ideally, these two approaches should be combined in a holistic approach to restoration preservation. SIGNIFICANCE: The oral cavity is a complex environment that poses an array of challenges to long-term material success; materials testing conditions should be comprehensive and closely mimic pathogenic oral conditions.

PMID- 30301626 TI - Hip Arthroscopy in Patients Ages 50 Years or Older: Minimum 5-Year Outcomes, Survivorship, and Risk Factors for Conversion to Total Hip Replacement. AB - PURPOSE: To report minimum 5-year outcomes and risk factors for conversion to total hip arthroplasty (THA) in patients >=50 years old undergoing hip arthroscopy to treat labral tears and femoroacetabular impingement (FAI). METHODS: Data were prospectively collected on patients who underwent hip arthroscopy to treat labral tears and FAI between February 2008 and January 2012. The inclusion criteria were >=50 years old at surgery, arthroscopic treatment for both labral tears and FAI, and preoperative patient-reported outcome (PRO) scores for modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and Visual Analog Scale (VAS). The exclusion criteria were Tonnis grade > 1 and previous hip conditions or surgeries. RESULTS: Of 103 eligible cases, 94 hips (91.3%) had minimum 5-year follow-up at a mean of 70.1 months (range, 60.0-95.1 months). All PROs and VASs demonstrated significant improvement at latest follow-up (P = .0001). Mean patient satisfaction was 8.4. All mean scores demonstrated durability from 2 years to latest follow-up, and NAHS (P = .009), HOS-SSS (P = .02), and VAS (P = .04) continued to significantly improve. Fifty-one (54.3%) of cases reached patient acceptable symptomatic state for mHHS, and 49 cases (52.1%) achieved minimal clinically important difference for this outcome measure. Four cases (4.3%) required secondary arthroscopy, and survivorship was 72.3%. Compared with survivors, the subgroup requiring THA demonstrated higher body mass indexes (P = .01), had larger alpha angles (P = .0200) and smaller lateral center-edge angles (P = .0200), and had higher proportions of Tonnis grade 1 (P = .0012), acetabular Outerbridge grade >= 2 (P = .0500), and femoral head Outerbridge grade >=2 (P = .0001). CONCLUSIONS: Hip arthroscopy for the treatment of labral tears and FAI in patients >=50 years old demonstrates statistically significant PRO improvements at minimum 5-year follow-up. However, due to potential for subsequent need for THA in a subset of this population, surgeons should use rigorous selection criteria and counsel patients appropriately.

PMID- 30301627 TI - Preoperative and Intraoperative Predictors of Long-Term Acceptable Knee Function and Osteoarthritis After Anterior Cruciate Ligament Reconstruction: An Analysis Based on 2 Randomized Controlled Trials. AB - PURPOSE: To determine preoperative predictors of long-term acceptable knee function and the development of osteoarthritis (OA) in long-term follow-up after anterior cruciate ligament (ACL) reconstruction. METHODS: This study is a long term follow-up of 2 previous randomized controlled trials that included 193 patients who underwent unilateral ACL reconstruction with ipsilateral hamstring tendon or patellar tendon autografts. Patients who suffered multiligament injuries, major meniscal injuries, chondral lesions requiring surgical treatment, or had a previous ACL reconstruction were excluded. Patient demographics, preoperative clinical assessments, and intraoperative findings were used to create stepwise multivariable regression models to determine the patient acceptable symptom state (PASS) in the International Knee Documentation Committee and the development of OA defined as a Kellgren-Lawrence grade >=2. Knee laxity measurements, hop performance, patient-reported outcome, and concomitant injuries were determined as variables. RESULTS: A total of 147 patients (63.7% men) were eligible for inclusion, with a mean follow-up of 16.4 +/- 1.3 years. The patients were an average age of 27.9 +/- 8.3 years at the time of ACL reconstruction. One half of the cohort reported an International Knee Documentation Committee evaluation system score above the PASS cutoff. The presence of a concomitant injury at operation (odds ratio [OR], 2.61; 95% confidence interval [CI], 1.10 6.21; P = .030) and greater preoperative anteroposterior laxity (OR, 1.87; 95% CI, 1.05-3.35; P = .034) increased the likelihood of achieving a PASS. A longer period between ACL injury and reconstruction (OR, 2.25; 95% CI, 1.02-5.00; P = .046) and older age at reconstruction (OR, 2.28; 95% CI, 1.34-3.86; P = .0023) increased the odds of developing OA at follow-up. CONCLUSIONS: Patients who were older at the time of ACL reconstruction and had waited >1 year between the injury and reconstruction ran an increased risk of having OA 16 years after reconstruction. One in 2 patients reported acceptable long-term knee function, but no risk factor for poorer subjective knee function was identified. Patients who had a minor concomitant injury and increased preoperative anteroposterior knee laxity had increased odds of reporting an acceptable long-term knee function.

AB - PURPOSE: To clarify the discrepancy in surgical options and present evidence to treat patellar dislocation by evaluating which of the techniques yields better improvement in stability and functional recovery for patellar dislocation. METHODS: The MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Web of Science, and Scopus electronic databases were searched for relevant articles comparing the outcomes of medial patellofemoral ligament (MPFL) treatment published up until August 2017. Data searching, extraction, analysis, and quality assessment were performed based on The Cochrane Collaboration guidelines. Clinical outcomes were evaluated using various outcome values in various techniques. For results with high heterogeneity, 95% prediction intervals (PIs) were also investigated. RESULTS: Eleven clinical studies were investigated. In patients with primary patellar dislocation, there were no significant differences in all evaluated outcomes between the conservative and surgical treatment groups. For patients with recurrent patellar dislocation, MPFL reconstruction was associated with a favorable Kujala score (mean difference, -8.91; 95% confidence interval, -14.05 to -3.77; I2 = 94%; 95% PI, -9.64 to -8.1) and Lysholm score (mean difference, -13.51; 95% confidence interval, -21.35 to -5.68; I2 = 96%; 95% PI, -14.86 to -12.16) when compared with soft tissue realignment surgery. CONCLUSIONS: Although surgical treatment of the MPFL for primary patellar dislocation is not superior to conservative treatment in restoring knee function and clinical outcomes, MPFL reconstruction is associated with more favorable clinical outcomes compared with medial soft tissue realignment surgery in patients with recurrent patellar dislocation. Double-bundle MPFL reconstruction seems to provide more favorable outcomes than single-bundle MPFL reconstruction, but this finding should be interpreted with caution because the evidence levels were low and were from only a few studies.

AB - PURPOSE: To determine whether bacterial DNA will be detectable by polymerase chain reaction (PCR) in torn graft tissue at the time of revision anterior cruciate ligament reconstruction (ACLR). METHODS: A total of 31 consecutive revision ACLR cases from 1 center from 2014-2016 were recruited. No patients had clinical signs of infection on presentation. Torn graft tissue was obtained in revision cases and subjected to clinical culture and PCR analysis with a universal bacterial primer. Fluorescence microscopy was used to confirm the presence of a biofilm. We obtained negative control samples of water open to air on the field and excess primary ACLR graft tissue, as well as torn native ligament, to evaluate for PCR positivity due to environmental contamination. RESULTS: Clinical cultures were positive (coagulase-negative Staphylococcus) in 1 revision case (3%, 1 of 31). Bacterial DNA was detectable in most revision ACLR cases (87.0%, 27 of 31), and there was a low rate of PCR positivity in negative control samples of water open to air (0%, 0 of 3), excess primary ACLR graft tissue after passage (20%, 1 of 5), or native torn ligament (20%, 1 of 5). Bacterial biofilm presence on failed graft tissue as well as monofilament suture was visually confirmed with fluorescence microscopy. CONCLUSIONS: Bacterial DNA is frequently present in failed ACLR grafts, with high rates of DNA detection by PCR but low culture positivity. LEVEL OF EVIDENCE: Level IV, case series. PMID- 30301630 TI - Type VIII SLAP Repair at Midterm Follow-Up: Throwers Have Greater Pain, Decreased Function, and Poorer Return to Play. AB - PURPOSE: To evaluate and compare midterm outcomes and return to play (RTP) of throwers and nonthrowers who underwent type VIII SLAP repair. METHODS: With 4 year minimum follow-up, stability, pain, range of motion (ROM), Kerlan-Jobe Orthopaedic Clinic (KJOC), and American Shoulder and Elbow Surgeons (ASES) scores; surgical satisfaction; and RTP were compared between throwing and nonthrowing athletes who underwent repair of type VIII SLAP lesions between 2003 and 2014. RESULTS: 46 patients (27 throwers and 19 nonthrowers) were included. The athletes were aged 24.2 +/- 9.2 years at the time of surgery. The mean follow up period was 6.6 +/- 2.0 years. A significant improvement in stability, pain, ROM, KJOC, and ASES scores was seen after surgery in both throwers and nonthrowers (P < .05). When postoperative outcomes were compared, throwers had more pain (P = .047), decreased ROM (P = .03), lower KJOC scores (52.2 +/- 24.0 in throwers vs 87.5 +/- 18.8 in nonthrowers, P < .0001), and lower ASES scores (43.5 +/- 7.1 in throwers vs 48.3 +/- 3.0 nonthrowers, P = .02). There was no difference in stability (P = .06), surgical satisfaction (96.3% in throwers vs 100% in nonthrowers, P > .99), or overall RTP (70.4% in throwers vs 94.7% in nonthrowers, P = .06). However, throwers were less likely to RTP at their preoperative level (37.0% in throwers vs 73.7% in nonthrowers, P = .02). CONCLUSIONS: Surgical repair of type VIII SLAP tears led to significant improvements in stability, pain, ROM, and outcome scores at midterm follow-up. Compared with nonthrowers, throwers had significantly more pain, less ROM, and worse function. Throwers were also less likely to RTP at their preoperative level. These findings suggest that type VIII SLAP tears should be repaired in all athletes because outcomes do improve, although throwers require specific counseling and expectation management regarding their ability to RTP at their preinjury level.

PMID- 30301631 TI - Primary Anterolateral Ligament Rupture in Patients Requiring Revision Anterior Cruciate Ligament Reconstruction: A Retrospective Case-Control Magnetic Resonance Imaging Review. AB - PURPOSE: To compare the initial rate of anterolateral ligament (ALL) injury at the time of anterior cruciate ligament (ACL) rupture in patients who subsequently experienced ACL reconstruction graft failure versus patients who did not experience subsequent ACL reconstruction graft failure. METHODS: Our institution's electronic medical record database was queried for patients who underwent primary ACL reconstruction with subsequent ACL graft rupture. Exclusion criteria included unavailable MRI scan, chronic ACL injury, multi-ligamentous injury, previous ACL reconstruction, and age younger than 13 or older than 50 years. Each patient was paired with an age-, gender-, and graft-matched control who underwent ACL reconstruction without subsequent graft rupture. Each patient was diagnosed with an intact, partially injured, or fully ruptured ALL on initial MRI. The location of ALL injury was also noted. The incidence and location of ALL rupture were compared using chi2 analysis. RESULTS: 1,967 patients underwent primary ACL reconstruction. 128 patients experienced ACL graft rupture, and 55 patients (43%) had MRI scans available for review. 39 of these patients fulfilled inclusion criteria and were matched with a control patient. In the revision group, the ALL was diagnosed as intact, partially torn, and completely torn in 17, 14, and 8 patients, respectively, compared to 18, 13, and 8 patients, respectively in the control group. No difference was found in frequency of ALL rupture (Pearson chi2 = 0.066; P = .968) or rupture location (Pearson chi2 = 4.00, P = 0.135). CONCLUSIONS: The incidence of initial ALL injury as documented on MRI was not different in patients who experienced subsequent ACL graft rupture compared with patients who did not experience ACL graft rupture after primary ACL reconstruction. The ALL was more commonly injured on the tibial side in patients with ACL graft rupture and femoral-sided lesions were more common in control patients.

PMID- 30301632 TI - Identification of a Patient Acceptable Symptomatic State Score for the International Hip Outcome Tool in People Undergoing Hip Arthroscopy. AB - PURPOSE: To determine a Patient Acceptable Symptomatic State (PASS) score for the 33-item International Hip Outcome Tool (iHOT-33) in people undergoing hip arthroscopy for primary diagnoses of femoroacetabular impingement syndrome, acetabular labral tears, and/or ligamentum teres pathology. METHODS: Consecutive participants underwent hip arthroscopy by a single surgeon between August 2011 and May 2016. Participants were included if they were between ages 18 and 60 years and underwent hip arthroscopy for femoroacetabular impingement syndrome, acetabular labral tears, or ligamentum teres pathology. Participants were excluded if they did not speak sufficient English to complete the iHOT-33, had evidence of hip dysplasia, had less than 2 mm of joint space on anteroposterior radiograph, or underwent subsequent total hip replacement surgery. Participants completed the iHOT-33 preoperatively and at a minimum of 1 to a maximum of 5 years postoperatively. Participants were also asked to answer yes or no to the external anchor question of "Taking into account all the activities you do during your daily life, your level of pain and also your functional impairment, are you satisfied with your current state following your surgery?" A receiver operating characteristic (ROC) curve was used to identify the PASS score. Multiple logistic regression was performed to determine if patient factors, primary preoperative diagnosis, or intraoperative findings predicted achievement of the PASS score. RESULTS: A total of 117 participants undergoing hip arthroscopy were included: 72 women (61.1%) and 45 men (38.5%) with mean age of 36.81 years (18-59). Forty-two (35.9%) had cam morphology, 18 (15.4%) had pincer morphology, 78 (67.2%) had labral tears, and 97 (82.9%) had ligamentum teres tears. Mean time to final follow-up was 2.25 years (range, 1-5). The PASS score at a mean of 2.25 years postoperatively was 58 as determined by the cutoff threshold on the ROC curve with the lowest difference between sensitivity and specificity (area under the ROC curve 0.88; P < .01; 95% confidence interval [CI], 0.81-0.95). No factors were predictors of achievement of the PASS score in this study (P > .05), including age (odds ratio [OR], 0.71; 95% CI, 0.32-1.56), sex (OR, 1.02; 95%, CI 0.98-1.06), preoperative iHOT-33 score (OR, 1.002; 95% CI, 0.98-1.03), primary preoperative diagnosis (OR, 0.86; 95% CI, 0.53-1.40), cam morphology (OR, 1.19; 95% CI, 0.54-2.64), Pincer morphology (OR, 0.50; 95%, CI 0.18-1.38), acetabular labral tears (OR, 1.93; 95% CI, 0.88-4.26), Outerbridge grade 3-4 chondral damage (OR, 0.97; 95% CI, 0.42-2.25), and ligamentum teres pathology (OR, 0.95; 95% CI, 0.35-2.61). CONCLUSIONS: This study reports a PASS score of 58 for the iHOT-33 at 2 years following hip arthroscopy. The PASS score will assist in assessing response to hip arthroscopy in research and clinical settings. LEVEL OF EVIDENCE: Level II, retrospective prognostic study. PMID- 30301633 TI - Loop Length Change of an Adjustable-Length Femoral Cortical Suspension Device in Anatomic Rectangular Tunnel Anterior Cruciate Ligament Reconstruction With a Bone Patellar Tendon-Bone Graft and Associated Clinical Outcomes. AB - PURPOSE: To evaluate loop length changes of an adjustable femoral cortical suspensory fixation device and assess the clinical results after anatomic rectangular tunnel anterior cruciate ligament (ART-ACL) reconstruction with a bone-tendon-bone (BTB) graft. METHODS: The study included 50 patients who underwent ART-ACL reconstruction with a BTB graft fixed using the adjustable length device BTB TightRope for femoral fixation between July 2013 and December 2014. Computed tomography examinations were performed at 1 and 12 weeks after the surgery. Loop length was measured in the reconstructed plane just parallel to the femoral tunnel, including the bone plug and the button. Measurement was performed thrice, and the mean value was used. Loop length change was defined as the difference in loop length between 1 and 12 weeks after the surgery. A paired t test was conducted with the effect size for statistical analysis. At 2 years postoperatively, clinical evaluations, including subjective and objective assessments, were performed. RESULTS: The mean loop lengths at 1 and 12 weeks were 25.77 +/- 3.88 mm and 25.81 +/- 3.89 mm, respectively, with a significant difference (P = .01). However, the effect size was 0.01, suggesting that the difference was not meaningful. The mean individual loop length change was 0.04 +/ 0.13 mm. All individual loop length changes were within the measurement error range. At 2 years postoperatively, 49 patients (98%) were graded as normal or nearly normal according to the International Knee Documentation Committee form. The mean side-to-side difference in anterior laxity at manual maximum force was 0.2 +/- 0.5 mm. CONCLUSIONS: The loop length change of an adjustable-length femoral cortical suspension device was negligible after ART-ACL reconstruction with a BTB graft. This ART-ACL reconstruction with a BTB graft using an adjustable-length device could safely provide sufficient stability to the operated knee. LEVEL OF EVIDENCE: Level IV, therapeutic case series. PMID- 30301634 TI - Return to Golf After Arthroscopic Management of Femoroacetabular Impingement Syndrome. AB - PURPOSE: To investigate if patients who reported playing golf before arthroscopic hip surgery for femoroacetabular impingement syndrome were able to return to playing golf postoperatively. METHODS: The study was a retrospective analysis of all consecutive patients undergoing hip arthroscopy for femoroacetabular impingement syndrome between 2012 and 2014. Inclusion criteria required that a patient (1) reported playing golf before the surgery, (2) had a minimum 2-year follow-up, and (3) completed patient-reported outcome measures. An electronic postoperative return to golf questionnaire was completed by patients who reported golf as an activity. To evaluate patients' ability to return to golf after surgery, the following variables were analyzed with paired samples t test and chi square tests: handedness, holes played, modified-Harris Hip Score, and Hip Outcome Score Activity of Daily Living and Sports-Specific Subscale. RESULTS: A total of 29 patients (22 men; age, 36.0 +/- 11.9 years) with a minimum of 24 months of follow-up who self-reported playing golf preoperatively were included in the analysis. Preoperatively, 23 patients (79%) had discontinued golfing owing to activity-related hip complaints. At the final follow-up, all patients had significant improvements in the Hip Outcome Score Activity of Daily Living (preoperatively, 65.9 +/- 19.9; postoperatively, 91.5 +/- 12.8; P < .0001), the Hip Outcome Score Sports-Specific Subscale (38.2 +/- 23.5, 79.7 +/- 28.8; P = .0002), and modified-Harris Hip Score (54.8 +/- 15.6; 84.2 +/- 15.8; P < .0001). Additionally, there was a decrease in pain from 7.34 +/- 1.63 to 1.71 +/- 2.3 postoperatively (P < .0001), and 97% of patients returned to golf at an average of 7.2 months postoperatively. Postoperatively, 55% of patients (n = 16) noted improved golfing performance, 41% (n = 11) returned to their preinjury level, 1 patient (3%) returned at a lower level owing to non-hip-related problems, and 1 (3%) did not return to golf owing to fear of reinjury. CONCLUSIONS: Arthroscopic treatment of femoroacetabular impingement syndrome in patients who reported playing golf before surgery resulted in significant improvements in hip function and predictably high rates of patient satisfaction, with 97% returning to golfing activity and 55% noting improvement from preinjury sporting performance.

AB - BACKGROUND: Intrahepatic cholangiocarcinomas (ICCs) are primary liver malignancies and are the second most common type of malignancy after hepatocellular carcinoma. ICCs are heterogeneous in clinical features, genotype, and biological behavior, suggesting that ICCs can initiate in different cell lineages. AIM: We investigated intrahepatic cholangiocarcinoma RBE cell lines for the markers neural cell adhesion molecule (NCAM) and c-Kit, which possess hepatic progenitor cells properties. METHODS: NCAM + c-Kit + cells were tested for hepatic progenitor cell properties including proliferation ability, colony formation, spheroid formation, and invasiveness in NOD/SCID mice. The Agilent Whole Human Genome Microarray Kit was used to evaluate differences in gene expression related to stem cell signaling pathways between NCAM + c-Kit + and NCAM-c-Kit- subset cells. Microarray results were further confirmed by real-time RT-PCR. RESULTS: NCAM + c-Kit + cells showed hepatic progenitor cell-like traits including the abilities to self-renew and differentiate and tumorigenicity in NOD/SCID mice. Differences were observed in the expression of 421 genes related to stem cell signaling pathways (fc >= 2 or fc <= 0.5), among which 231 genes were upregulated and 190 genes were downregulated. CONCLUSION: NCAM + c-Kit + subset cells in RBE may have properties of hepatic progenitor cells. NCAM combined with c-Kit may be a valuable marker for isolating and purifying ICC stem/progenitor cells. PMID- 30301636 TI - A potential clinical significance of DAB2IP and SPRY2 transcript variants in prostate cancer. AB - Deregulation of key signaling pathways is one of the primary phenomena in carcinogenesis. DAB2IP and SPRY2 are regulatory elements, which act as feedback inhibitors of receptor tyrosine kinases signaling in mitogen-activated protein kinase pathway. These elements have also been implicated in the pathophysiology of cancer. Therefore, this study is aimed to investigate the expression of all known splice variants of DAB2IP and SPRY2 in prostate tissue. Fresh Prostate tissue samples (50 prostate cancer/ matched normal tissue and 30 BPH) were collected and total RNA was extracted followed by cDNA synthesis. The expression of DAB2IP and SPRY2 transcript variants were evaluated using RT-PCR and quantitative Real-time PCR. The results indicated significant down-regulation of DAB2IP transcript variant 1 in cancerous tissues compared to paired normal tissues (P = 0.001) as well as SPRY2 transcript variant 2 in cancerous tissues in comparison with the normal counterparts and BPH (P = 0.008 and P = 0.025, respectively). In addition, there was a significant negative correlation between DAB2IP.1 and SPRY2.2 expression with PSA levels in prostate cancer (P = 0.039 rho =-0.24 and P = 0.045 rho =-0.3, respectively). Interestingly, the down-regulation of DAB2IP.1 mRNA and SPRY2.2 mRNA was positively correlated in tumor samples (P = 0.002 rho = 0.434). For the first time, this experiment highlights the deregulation of DAB2IP and SPRY2 transcript variants in human prostate cancer. The present study confirms and extends the previous reports through indicating transcript-specific down-regulation and significant association of DAB2IP and SPRY2 in prostate tumorigenesis. PMID- 30301638 TI - Restricted self-diffusion of adsorbed water in MIL-100(Al). AB - An extended two-site exchange model is presented, which is used to evaluate pulsed field gradient (PFG) nuclear magnetic resonance (NMR) measurements of water in the nanoporous metal-organic framework MIL-100(Al). Here the water molecules exchange between the inter- and the intracrystalline space during the observation time, but are also restricted in their movement by the crystal surface. The evaluation of temperature and loading dependent PFG NMR data yields information about the intracrystalline diffusion process, the radius of the restricting geometry and the time constants of the exchange process. The intracrystalline mean residence time is found to decrease with increasing temperature, which allows an estimate of the heat of adsorption under the equilibrium conditions of the NMR measurements.

AB - Understanding the reactivity and mass transport properties of porous heterogenous catalysts is important for the development of new materials. Whereas MRI has previously been used to correlate chemical kinetics and hydrodynamics under operando conditions, this paper demonstrates that a modern benchtop NMR spectrometer is a suitable alternative to obtain diverse reaction information in porous heterogeneous catalyst materials on a smaller scale. Besides information about the chemical conversion within the pores, it can also be used to study changes of surface interaction by T1/T2 NMR relaxometry techniques and changes in mass transport by PFG NMR from a single chemical reaction. PMID- 30301637 TI - Large International Validation of ABSIS and PDAI Pemphigus Severity Scores. AB - The Pemphigus Disease Area Index (PDAI) and Autoimmune Bullous Skin Disorder Intensity-Score (ABSIS) scores have been proposed to provide an objective measure of pemphigus activity. These scores have been evaluated only on already treated patients mainly with mild to moderate activity. The objective was to assess the interrater reliability of ABSIS and PDAI scores and their correlation with other severity markers in a large international study. Consecutive patients with newly diagnosed pemphigus were enrolled in 31 centers. Severity scores were recorded during a 24-month period by the same two blinded investigators. Serum was collected at each visit for ELISA measurement of anti-desmoglein antibodies. The intraclass correlation coefficient (ICC) and Spearman rank correlation coefficient were calculated. A total of 116 patients with pemphigus vulgaris (n = 84) or pemphigus foliaceus (n = 32) were included. At baseline, the ABSIS and PDAI ICCs were 0.90 (95% confidence interval [CI] = 0.85-0.93), and 0.91(95% CI = 0.87-0.94), respectively. The ICCs for PDAI were higher in moderate and extensive pemphigus (ICC = 0.82, 95% CI = 0.63-0.92 and ICC = 0.80, 95% CI = 0.62-0.90, respectively) than in patients with intermediate (significant) extent (ICC = 0.50, 95% CI = 0.27-0.68). Conversely, the ICCs for ABSIS were lower in patients with moderate extent (ICC = 0.44, 95% CI = 0.004-0.74) than in those with intermediate or extensive forms, (ICC = 0.69, 95% CI = 0.51-0.81 and ICC = 0.75, 95% CI = 0.51-0.88, respectively). During patients' follow-up, the ICCs of both ABSIS and PDAI scores remained higher than 0.70. ABSIS and PDAI skin (r = 0.71 and r = 0.75) but not mucosal (r = 0.32 and r = 0.37) subscores were correlated with the evolution of anti-DSG1 and anti-DSG3 ELISA values, respectively. ABSIS and PDAI scores are robust tools to accurately assess pemphigus activity. PMID- 30301641 TI - Impact of rotavirus vaccine introduction and genotypic characteristics of rotavirus strains in children less than 5 years of age with gastroenteritis in Ethiopia: 2011-2016. AB - INTRODUCTION: A monovalent rotavirus vaccine was introduced in the Ethiopian Expanded Program on Immunization from November 2013. We compared impact of rotavirus vaccine introduction on rotavirus associated acute diarrhea hospitalizations and genotypic characteristics of rotavirus strains pre-and post vaccine introduction. METHODS: Sentinel surveillance for diarrhea among children <5 years of age was conducted at 3 hospitals in Addis Ababa, Ethiopia from 2011 to 2017. Stool specimens were collected from enrolled children and tested using an antigen capture enzyme immunoassay. Rotavirus positive samples (156 from pre- and 141 from post-vaccination periods) were further characterized by rotavirus genotyping methods to identify the predominant G and P types circulating during the surveillance era. RESULTS: A total of 788 children were enrolled during the pre- (July 2011-June 2013) and 815 children during the post-vaccination (July 2014-June 2017) periods. The proportion of diarrhea hospitalizations due to rotavirus among children <5 years of age declined by 17% from 24% (188/788) in the pre-vaccine period and to 20% (161/185) in post-vaccine introduction era. Similarly, a reduction of 18% in proportion of diarrhea hospitalizations due to rotavirus in children <12 months of age in the post (27%) vs pre-vaccine (33%) periods was observed. Seasonal peaks of rotavirus declined following rotavirus vaccine introduction. The most prevalent circulating strains were G12P[8] in 2011 (36%) and in 2012 (27%), G2P[4] (35%) in 2013, G9P[8] (19%) in 2014, G3P[6] and G2P[4] (19% each) in 2015, and G3P[8] (29%) in 2016. DISCUSSION: Following rotavirus vaccine introduction in Ethiopia, a reduction in rotavirus associated hospitalizations was seen in all age groups with the greatest burden in children <12 months of age. A wide variety of rotavirus strains circulated in the pre- and post-vaccine introduction periods. PMID- 30301642 TI - The effect of exercise on local and systemic adverse reactions after vaccinations - Outcomes of two randomized controlled trials. AB - INTRODUCTION: An adverse reaction associated with vaccination is considered to be a key barrier to vaccinate, yet little attention has been given to interventions to reduce their occurrence. Exercise is a behavioural adjuvant which may also influence adverse reactions. Here, two randomized controlled trials are reported, examining the effects of exercise on self-reported adverse reactions following vaccination in adolescents and young adults. METHODS: Study one; 116 adolescents receiving the HPV vaccine were randomly allocated to either Control (n = 56) or Pre-vaccine Exercise (n = 60) group (2015-2016). Exercise consisted of 15-minutes upper body exercise. Study two; 78 young adults receiving the influenza vaccine were randomly allocated to either Control (n = 19), or one of 3 exercise groups: Pre-vaccine Arm (n = 19), Pre-vaccine Leg (n = 20) or Post-vaccine Arm (n = 20) (2017). Exercise included 15-minutes of arm or leg exercises prior to or after vaccination. All participants in both studies completed an adverse events diary for seven-days post-vaccination. RESULTS: Study one; Reported days of tenderness in female adolescents that exercised were significantly lower than control (p = 0.032), with a similar trend in reported days of pain (p = 0.050). Furthermore, days of feeling ill (p = 0.070) and reduced appetite (p = 0.067) were found to be lower with exercise, although not significant. Overall, female adolescents reported significantly more days of pain (p = 0.003), tenderness (p < 0.001), swelling (p = 0.011), and feeling ill (p = 0.0040). Study two; Exercise groups reported reduced days of swelling (p = 0.018), fever (p = 0.013), and lowered appetite (p = 0.011) across both genders. Furthermore, females reported reduced days of medication use with exercise (p = 0.034), and a trend toward reduced days of swelling (p = 0.052). DISCUSSION: In two separate trials, a short bout of exercise reduced reported adverse reactions after vaccinations for local and systemic adverse reactions. Gender differences in reported local and systemic adverse reactions were more evident among adolescents than young adults. These findings support the need for further work to examine the potential benefit of exercise in improving vaccination procedures. PMID- 30301643 TI - Posterior Interosseous Nerve Proximity to Cortical Button Implant for Distal Biceps Repair With Single and 2-Incision Approaches. AB - PURPOSE: Fixation with a cortical button is the biomechanically strongest surgical approach for distal biceps repair, and utilization of the 2-incision approach may provide a more anatomical repair and improved terminal supination strength. The risk of injury to the posterior interosseous nerve (PIN) associated with this approach requires further investigation. METHODS: A distal biceps repair with a cortical button was performed on 10 cadavers, 5 utilizing the single-incision approach and 5 utilizing the 2-incision approach. Contrast was injected into the radial nerve and computed tomography scans were obtained. The distance between the drilled cortical perforation and the PIN was measured. RESULTS: The mean distance from the cortical perforation to the PIN was not significantly different between approaches (9.4 mm and 8.8 mm). A PIN entrapment was seen in 0 out of 5 for the single-incision approach and 1 out of 5 for the 2 incision approach. CONCLUSIONS: Distal biceps repair with cortical button fixation places the PIN at risk of injury regardless of the approach used. Methods of fixation that require bicortical drilling should be especially avoided when using the 2-incision approach. CLINICAL RELEVANCE: Distal biceps repair utilizing bicortical drilling for fixation through a 2-incision approach poses high risk of injury to the PIN and should be avoided. PMID- 30301644 TI - Morphological Changes of the Median Nerve Within the Carpal Tunnel During Various Finger and Wrist Positions: An Analysis of Intensive and Nonintensive Electronic Device Users. AB - PURPOSE: To investigate the effects of static hand postures during various finger and wrist positions on morphological changes of the median nerve within the carpal tunnel in intensive and nonintensive electronic device users. METHODS: Forty-eight university students, equally divided into intensive and nonintensive users (>=5 h/d and <5 h/d of electronic device usage, respectively), were randomly selected after questionnaire responses and evaluated clinically and by ultrasonography. RESULTS: Intensive users reported more wrist/hand pain with a high severity score than nonintensive users. They also had larger median nerve cross-sectional areas, flattening ratios, and perimeters than nonintensive users, and showed less median nerve deformation under various finger and wrist positions. Compared with the neutral wrist position with all fingers extended for both intensive and nonintensive users, the cross-sectional areas decreased under finger flexion and grip, as well as wrist extension-flexion and radial-ulnar deviation. Overall, the average median nerve size of the dominant hand was much larger than that of the nondominant hand, especially for intensive users. CONCLUSIONS: Wrist deviation from neutral can lead to more pronounced deformation of the median nerve than finger flexion for both intensive and nonintensive users. To minimize compression on the median nerve, it is important to keep the wrist as near to the neutral position as possible during computer-related work and avoid keeping the thumb and fingers in a static flexed position when using mobile devices, especially for single-hand use. CLINICAL RELEVANCE: On the basis of this observational study, intensive users had enlarged and flattened median nerves as well as decreased nerve deformation during hand motions compared with nonintensive users. As overuse of electronic devices may adversely affect the median nerve, caution may be warranted. PMID- 30301645 TI - In Vivo Survival of Mesenchymal Stromal Cell-Enhanced Decellularized Nerve Grafts for Segmental Peripheral Nerve Reconstruction. AB - PURPOSE: Adipose-derived mesenchymal stromal cells (MSCs) have emerged as promising tools for peripheral nerve reconstruction. There is a paucity of information regarding the ultimate survivorship of implanted MSCs or whether these cells remain where they are placed. The aim of the present study was to track the in vivo distribution and survival of MSCs seeded on a decellularized nerve allograft reconstruction of a peripheral nerve defect using luciferase based bioluminescence imaging (BLI). METHODS: To determine the in vivo survivability of MSCs, autologous Lewis rat MSCs were stably labeled with luciferase by lentiviral particles. Labeled cells were dynamically seeded onto a Sprague Dawley decellularized rat nerve allograft and used to bridge a 10-mm sciatic nerve defect. The MSC survival was determined by performing in vivo BLI to detect living cells. Twelve animals were examined at 24 hours after implantation, 3, 7, 9, 11, and 14 days, and at daily intervals thereafter if signals were still present. RESULTS: Labeled MSCs could be detected for up to 29 days. Gradually diminishing BLI signals were observed within the first week following implantation. Implanted MSCs were not detected anywhere other than the site of surgery. CONCLUSIONS: The MSCs seeded on decellularized nerve allografts can survive in vivo but have finite survival after implantation. There was no evidence of migration of MSCs to surrounding tissues. CLINICAL RELEVANCE: The findings support a therapeutic approach that combines MSCs with a biological scaffold for peripheral nerve surgery. It provides understanding of the viability and distribution of implanted MSCs, which is a prerequisite before clinical translation can be considered. PMID- 30301648 TI - Stable and efficient partial nitritation granular sludge reactor treating domestic sewage at low temperature. AB - The success of combined partial nitritation (PN) and anammox process treating low strength domestic wastewater depends on achieving a stable and efficient PN. In this study, desirable PN for domestic sewage with low temperature of 11.8-16.9 degrees C was achieved in a granular sludge reactor operated in anaerobic/aerobic (A/O) mode. Average nitrite accumulation ratio of 97.3% was obtained with an effluent nitrite/ammonium ratio of 1.2 for influent ammonium of 39.3-78.7 mg.L-1. Quantitative microbial analysis and activity batch test showed that nitrite oxidizing bacteria (NOB) were effectively suppressed, while ammonium oxidizing bacteria (AOB) were dominant. For the efficient suppression of NOB, A/O mode, aerobic phosphorus uptake and granular sludge could play important roles. Furthermore, high AOB activity was obtained with an average ammonium oxidation rate of 11.6 mg N.L-1.h-1, which could be due to the abundant psychrotolerant microorganisms, increased content of extracellular polymeric substances and relatively high dissolved oxygen condition of the reactor. PMID- 30301646 TI - Overstuffing of Unstable Scaphoid Nonunions: A Radiographic Analysis of Carpal Parameters. AB - PURPOSE: The purpose of this study was to radiographically evaluate scaphoid length and carpal parameters before and after reconstruction of nonunions with interposition vascularized medial femoral condyle (MFC) bone graft to determine if the scaphoid was overstuffed or if normal anatomy was restored and to determine the effect on ulnar carpal translocation when the volar radiocarpal ligaments were left unrepaired. METHODS: Thirty-nine patients with established scaphoid nonunions with carpal collapse were reconstructed by interposition vascularized MFC bone grafts without repair of the volar radiocarpal ligaments. Pre- and postoperative radiographs and computed tomography scans of the 39 patients were reviewed. The scaphoid length, capitate-ulnar distance ratio (CUDR), modified carpal height ratio (MCHR), radiolunate (RL) and scapholunate (SL) angles were measured before and 3 months after surgery. Thirteen of these patients had contralateral wrist radiographs that were used for analysis of scaphoid length restoration. RESULTS: No significant changes were observed for CUDR and MCHR before and after surgery. The length of the scaphoid significantly improved after reconstruction from 21.9 +/- 3.3 to 23.7 +/- 3.4 mm on posteroanterior x-ray views and from 24.0 +/- 2.2 to 27.7 +/- 2.8 mm on lateral views. The RL and SL angles also changed significantly after surgery from 19.5 degrees +/- 13.5 degrees to 4.1 degrees +/- 16.9 degrees and from 67.5 degrees +/- 12.5 degrees to 56.0 degrees +/- 12.5 degrees , respectively. Regarding the 13 patients with contralateral x-rays, no differences were seen on CUDR, MCHR, or scaphoid length on posteroanterior x-ray views. However, the scaphoid length on lateral x-ray views increased from 23.1 +/- 2.40 to 27.6 +/- 2.78 mm and was significantly longer than the contralateral side by 9.6%. The RL and SL angles were restored and comparable with the contralateral side. CONCLUSIONS: The use of vascularized MFC bone graft increased scaphoid length by 9.6% and restored normal carpal alignment. Despite the increased scaphoid length compared with the contralateral side, the lack of repair of the volar radiocarpal ligaments did not cause ulnar carpal translocation in short-term follow-up.

AB - OBJECTIVES: The aim was to compare the antimicrobial efficacy of four different grafts: a standard graft (Intergard, IG), an IG graft soaked in rifampicin (IGrif), a silver impregnated graft (Intergard Silver, IGS), and a silver + triclosan impregnated graft (Intergard Synergy, IGSy). METHODS: This was a seven day in vitro study. The IG, IGrif, IGS, and IGSy grafts were each contaminated separately with the following microorganisms: Staphylococcus epidermidis, Methicillin resistant Staphylococcus aureus (MRSA), Escherichia coli, and Candida albicans from both clinical and American Type Culture Collection (ATCC) origins. The in vitro antimicrobial efficacy was evaluated by time to kill assays at T0, T24h, T48h, T72h, and T168h. Bactericidal activity was defined as >3 log10 reduction factor (logRF). Additionally, Rifampicin, triclosan and silver resistance development were screened. RESULTS: As anticipated for the non antimicrobial IG, all microorganism strains proliferated. The IGSy and the IGS showed a seven day bactericidal efficacy (>3 logRF) for all tested microorganisms. This efficacy was confirmed at all time points for IGSy only, demonstrating faster bactericidal efficacy than IGS. The IGrif demonstrated a seven day bactericidal efficacy against the ATCC MRSA only, while showing no activity against C. albicans and ATCC E. coli. Regarding ATCC S. epidermidis, clinical MRSA and clinical E. coli, IGrif, although bactericidal at earlier time points, lost its antimicrobial efficacy at seven days leading to the emergence of rifampicin resistant mutants in four of six, two of six, and two of six assays, respectively. Mutant strains were also detected in ATCC MRSA in one of six assays. No triclosan or silver resistance has emerged at T7days. CONCLUSION: For all microorganisms tested, the Synergy graft combining silver with triclosan demonstrated a more sustainable and efficient seven day antimicrobial activity than the rifampicin soaked graft. The emergence of rifampicin resistant mutants suggests preference for a Synergy graft over a graft soaked in rifampicin, to prevent or treat an infection when a biological solution is not feasible. PMID- 30301649 TI - The association of variables of fibular reconstructed mandible and bite force in oral cancer patients with dental implant rehabilitation. AB - PURPOSE: The aim of this study was to investigate how the physical variables of fibular reconstructed mandibles with dental implants affects the relative bite force in oral cancer patients. MATERIALS AND METHODS: Over 7 years of follow-up, 13 oral cancer patients were enrolled who included 51 successful implants in the fibular flap. The tactile sensor analyzer evaluated the bite force. The crown implant ratio, fibular, and rehabilitated dental length were measured using radiographic images. Linear regression was used to analyze the bite force related to the variables of the implants in the fibular reconstructed mandible. RESULTS: Even when the results showed no statistical significance (P > 0.05), increasing the crown-implant ratio, length of the fibular flap, and implant prosthetic reconstructed dentition had a tendency to decrease the bite force (estimate from 0.08% to -4.27%); there was a positive trend of occlusal force and the length of rehabilitative dentition compared with the dental antagonist (estimate = 6.95). CONCLUSION: In this study, the crown-implant ratio, implant dentition, and fibular flap length revealed no significant impact on the bite force or implant success in oral cancer patients; however, a trend to weaken the bite force was suggested once the numerical values of these variables increased. PMID- 30301650 TI - Effects of systemic erythropoietin treatment and heterogeneous xenograft in combination on bone regeneration of a critical-size defect in an experimental model. AB - The aim of the present study was to evaluate the effects of systemic EPO treatment alone or in combination with xenogenic bone graft augmentation on bone regeneration. Eleven adult male Sprague-Dawley rats were used in the present study. Rats were subjected to bilateral 5 mm critical size bone defects on the parietal bones under general anaesthesia. Right parietal bone defects were augmented with xenogenic bone graft and left parietal bone defect was left empty. Rats were randomly assigned for one of the two groups. One group of rats received (i) vehicle (n = 6) and other group received (ii) EPO (500IU kg/day) (n = 5). EPO treatment was continued for 28 days. Vascularization was analysed by immunohistochemical staining of CD31 (PECAM-1) and new bone formation was histomorphometrically evaluated. Xenogenic graft augmentation enhanced bone formation and vascularization significantly in either vehicle or EPO treated groups (p < 0.05). Histomorphometric results of angiogenesis was similar in the EPO treated group and the control group. However, angiogenesis was significantly higher in the combination of systemic EPO treatment with graft augmentation than graft augmentation alone (p < 0.01). Graft augmentation for treatment of critical size bone defects seems essential for proper bone healing. Results of the present study suggest that EPO potentiates the regenerative processes of augmented bone defects. PMID- 30301651 TI - Relapse tendency after BSSO surgery differs between 2D and 3D measurements: A validation study. AB - Bilateral sagittal split ramus osteotomy (BSSO) surgery is used to correct various dento-skeletal deformities. Clinical outcomes are critically dependent on accurate and proper positioning of skeletal units created by BSSO. Monitoring skeletal changes postoperatively is a major part of follow-up. Between January 2015 and December 2015, 24 patients underwent BSSO surgery without any other segmental osteotomy (mean age, 29.9 +/- 14.2 [range, 17-67] years; 18 females). Cephalometric X-rays and cone-beam computed tomography scans were performed 6 weeks and 12 months postoperatively. We compared the position displacement at three mandibular points at both postoperative time points using 2- and 3 dimensional analysis separately and examined the relationship between these methods. Horizontally in at least in 14/24 patients, the difference between 2 dimensional and 3-dimensional measurements was >1 mm. Vertically in at least in 16/24 patients, the difference between 2-dimensional and 3-dimensional measurements was >1 mm. A scatter plot with orthogonal regression indicated the relationships between the 2-dimensional measurement and the corresponding 3 dimensional measurement in the horizontal and vertical directions. Skeletal relapse with 2-dimensional-measurements differed significantly from the 3 dimensional measurements. There was no evidence of a relationship between the two types of measurements regarding the direction and the location of the landmarks. PMID- 30301652 TI - Visualization and quantification of tongue movement during articulation: Is ultrasound a valid alternative to magnetic resonance imaging? AB - BACKGROUND: Quality of life in tumour patients following combined ablative and reconstructive head and neck surgery varies significantly. This is at least partially due to differences in speech and swallowing function. A tool to objectively evaluate articulation by magnetic resonance imaging (MRI) has now been tested alongside ultrasound examination. PATIENTS AND METHODS: A standardized sequence of phonemes from the German language was established in 20 healthy volunteers and recorded in different planes by MRI and ultrasound. Phonemes were identified through recognition of typical tongue configurations by two different observers. An algorithm for metric analysis of articulation in terms of distances and angles for five extreme points on the tongue (anterior, posterior, cranial and two basal corners) was designed. The findings in these volunteers were subsequently compared with the results of an examination of a tumour patient. RESULTS: Physiological articulation was visualized and evaluated both by MRI and ultrasound. There was a high intra-class correlation coefficient for measurements between independent observers. Tongue position for certain phonemes was mostly constant in healthy patients of different age groups, with gender-specific differences. In a first comparison, tongue position in a patient with tongue cancer differed significantly from this position, both pre- and postoperatively. In agreement with clinical articulation quality, the tongue position of the patient returned to almost normal within 12 months postoperatively. CONCLUSION: Both ultrasound and MRI are appropriate instruments for visualization of articulation and objective measurements to evaluate speech in tumour patients. Whilst MRI is more precise and can identify more subtle differences, ultrasound is a valid alternative due to its wider availability and broader applicability. PMID- 30301653 TI - An introduction to the electronic waterpipe. AB - Despite the associated negative health outcomes, waterpipe smoking remains a popular method of tobacco consumption, specifically in young adults. While there have been expanding efforts to decrease waterpipe use, there is a new, non combustible waterpipe device on the market, the electronic waterpipe (e waterpipe), that could serve as an alternative to traditional, combustible waterpipe smoking. There is currently no known literature evaluating the e waterpipe including prevalence of use or its health risks. This mini review defines the e-waterpipe, explains how an e-head is used to construct an e waterpipe, and describes the various e-head models available for use. The review also discusses implications of e-head use and provides recommendations for future research and regulation. PMID- 30301654 TI - Using public health surveillance data to measure Clostridium difficile infection population burden in Massachusetts. AB - Clostridium difficile occurs both inside and outside of health care facilities, but surveillance has been traditionally limited to the hospital setting. To measure the population-based burden of C difficile infection (CDI), we used multiple routine sources of data. We found an overall rate of CDI in Massachusetts in 2016 of 132.5 per 100,000 population, with mortality in 2014 of 6.4 per 100,000 population. Population-based measurement of CDI burden appears feasible without conducting a special study. PMID- 30301655 TI - Effect of varying federal definitions on prevalence and characteristics associated with carbapenem-resistant Enterobacteriaceae in veterans with spinal cord injury. AB - BACKGROUND: Patients with spinal cord injury (SCI) have a high risk for multidrug resistant organisms, including carbapenem-resistant Enterobacteriaceae (CRE). Accurate and easily applied definitions are critical to identify CRE. This study describes CRE and associated characteristics in veterans with SCI per Centers for Disease Control and Prevention (CDC) and Department of Veterans Affairs (VA) definitions. METHODS: A retrospective cohort of veterans with SCI and more than 1 culture with Escherichia coli, Klebsiella spp and/or Enterobacter spp between 2012 and 2013 was examined. Antibiotic susceptibility criteria of pre-2015 (CDC1) and post-2015 (CDC2) CDC definitions and pre-2017 (VA1) and post-2017 (VA2) VA definitions were used to identify CRE. CRE prevalence and characteristics are described for isolates meeting each definition, and agreement was assessed with the Cohen kappa. RESULTS: We reviewed 21,514 isolates cultured from 6,974 veterans; 423 isolates met any CRE definition. Although agreement among definitions was high (kappa = 0.82-0.93), definitions including ertapenem resistance led to higher CRE prevalence (VA1 = 1.7% and CDC2 = 1.9% vs VA2 = 1.4% and CDC1 = 1.5%). Forty-four of 142 VA facilities had more than 1 CRE case defined by VA2; 10 facilities accounted for 60% of CRE cases. Almost all CRE was isolated from high-complexity, urban facilities, and the South had the highest proportion of CRE. CONCLUSIONS: Varying federal definitions give different CRE frequencies in a high-risk population. Definitions including ertapenem resistance resulted in higher CRE prevalence but may overemphasize noncarbapenemase isolates. Thus, both federal definitions now highlight the importance of carbapenemase testing. PMID- 30301656 TI - A novel personal protective equipment coverall was rated higher than standard Ebola virus personal protective equipment in terms of comfort, mobility and perception of safety when tested by health care workers in Liberia and in a United States biocontainment unit. AB - BACKGROUND: During the 2014-2016 Ebola virus epidemic, more than 500 health care workers (HCWs) died in spite of the use of personal protective equipment (PPE). The Johns Hopkins University Center for Bioengineering Innovation and Design (CBID) and Jhpiego, an international nongovernmental organization affiliate of Johns Hopkins, collaborated to create new PPE to improve the ease of the doffing process. METHODS: HCWs in Liberia and a US biocontainment unit compared standard Medecins Sans Frontiere PPE (PPE A) with the new PPE (PPE B). Participants wore each PPE ensemble while performing simulated patient care activities. Range of motion, time to doff, comfort, and perceived risk were measured. RESULTS: Overall, 100% of participants preferred PPE B over PPE A (P < .0001); 98.1% of respondents would recommend PPE B for their home clinical unit (P < .0001). There was a trend towards greater comfort in PPEB. HCWs at both sites felt more at risk in PPE A than PPE B (71.9% vs 25% in Liberia, P < .0001; 100% vs 40% in the US biocontainment unit, P < .0001). CONCLUSIONS: HCWs preferred a new PPE ensemble to Medecins Sans Frontiere PPE for high-consequence pathogens. Further studies on the safety of this new PPE need to be conducted. PMID- 30301657 TI - Laxative use and testing for Clostridium difficile in hospitalized adults: An opportunity to improve diagnostic stewardship. AB - BACKGROUND: It is recommended that that only unformed stool from patients with diarrhea be tested for Clostridium difficile infection. We determined the prevalence of and patient characteristics associated with antecedent laxative receipt among hospitalized adults undergoing C difficile testing. METHODS: In a case-control study of 5,452 C difficile tests from 5 hospitals in Southeast Michigan, patients who received laxatives (docusate, senna, polyethylene glycol 3350, bisacodyl, and magnesium hydroxide) in the 24 or 48hours before testing were identified. Logistic regression was performed to identify patient characteristics associated with laxative receipt before testing. RESULTS: In 535 (9.8%) and 707 (13%) tests, patients received laxatives in the 24 and 48hours before testing, respectively. The odds of antecedent laxative receipt were significantly greater for patients residing on a surgical service than a medical service (24hours odds ratio [OR], 2.5; 95% confidence interval [CI], 2.1-3.1; 48hours OR, 2.7; 95% CI, 2.3-3.2), patients residing in an intensive care unit (ICU) than a non-ICU (24hours OR, 1.3; 95% CI, 1.0-1.6; 48hours OR, 1.3; 95% CI, 1.1-1.6), and patients whose Elixhauser Comorbidity Score was 4 or higher (24hours OR, 1.4; 95% CI, 1.1-1.7; 48hours OR, 1.4; 95% CI, 1.2-1.7). CONCLUSIONS: Among patients tested for C difficile, antecedent laxative use was common. Improving diagnostic stewardship around C difficile testing, particularly in surgical and ICU patients, is a significant opportunity and priority for quality improvement. PMID- 30301658 TI - The role of short-term weather conditions in temporal dynamics of fire regime features in mainland Spain. AB - In this paper we investigate spatial-temporal associations of fire weather danger and fire regime features from 1979 to 2013. We analyze monthly time series of fire activity (number of fires and burned area) and fire weather danger rating indices (Fire Weather Index, Burning Index and Forest Fire Danger Index) at two spatial scales: (i) regionally, splitting the Spanish mainland into Northwest, Hinterland and Mediterranean regions; and (ii) locally, using the EMCWF grid. All analyses are based on decomposing time series to retrieve differential indicators of seasonal cycles, temporal evolution and anomalies. At regional scale we apply lagged cross-correlation analysis (4 lags or months before fire) to explore seasonal associations; and trend detection tests on the temporal evolution component. At the local scale, we calculate Pearson correlation coefficients between each individual index and the 18 possible fire-activity subsets according to fire size (all sizes, >1 ha and >100 ha) and source of ignition (natural, unintended and arson); this analysis is applied to both cycles, temporal and anomalies series. Results suggest that weather controls seasonal fire activity although it has limited influence on temporal evolution, i.e. trends. Stronger associations are detected in the number of fires in the Northwest and Hinterland regions compared to the Mediterranean, which has desynchronized from weather since 1994. Cross-correlation analysis revealed significant fire-weather associations in the Hinterland and Mediterranean, extending up to two months prior fire ignition. On the other hand, the association between temporal trends and weather is weaker, being negative along the Mediterranean and even significant in the case of burned area. The spatial disaggregation into grid cells reveals different spatial patterns across fire-activity subsets. Again, the connection at seasonal level is noticeable, especially in natural-caused fires. In turn, human-related wildfires are occasionally found independent from weather in some areas along the northern coast or the Ebro basin. In any case, this effect diminishes as the size of the fire increases. Our work suggests that for some regions of mainland Spain, these fire danger indices could provide useful information about upcoming fire activity up to two months ahead of time and this information could be used to better inform wildland fire prevention and suppression activities. PMID- 30301659 TI - An investigation on the capability of magnetically separable Fe3O4/mordenite zeolite for refinery oily wastewater purification. AB - Damage to the water resources and environment as a consequence of oil production and use of fossil fuels, has increased the need for applying various technologies and developing effective materials to remove contaminates from oily wastewaters resources. One of the challenges for an economic industrial wastewater treatment is separation and reusability of the developed purifying agents. Development of magnetic materials could potentially facilitate easier and more economic separation of purifying agents. Therefore, herein we have synthesised an efficient and easily recyclable Fe3O4/mordenite zeolite using a hydrothermal process to investigate its purification capability for wastewater from Kermanshah oil refinery. The synthesised Fe3O4/mordenite zeolite was characterised using XRD, FTIR, SEM, EDX, XRF and BET analysis. XRD result showed that the synthesised Fe3O4/mordenite zeolite comprised sodium aluminium silicate hydrate phase [01-072 7919, Na8(Al6Si30O72)(H2O)9.04] and cubic iron oxide phase [04-013-9808, Fe3O4]. Response Surface Method (RSM) combined with Central Composite Design (CCD) was used to identify the optimum operation parameters of the pollutant removal process. The effect of pH, contact time and Fe3O4/mordenite zeolite amount on the Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD) and Nephelometric Turbidity Unit (NTU) were investigated. It was found that pH was the most significant factor influencing COD and BOD removal but the quantity of Fe3O4/mordenite zeolite was the most influential factor on the turbidity removal capacity. The optimum removal process conditions were identified to be pH of 7.81, contact time of 15.8 min and Fe3O4/mordenite zeolite amount of 0.52% w/w. The results show that the regenerated Fe3O4/mordenite zeolite can be reused for five consecutive cycles in purification of petroleum wastes. PMID- 30301660 TI - Treatment of older patients with advanced non-small cell lung cancer: A challenge. AB - With a median age of 70 years at diagnosis, lung cancer is a disease of older persons. As a consequence oncologists are confronted with an increasing older lung cancer population for which treatment decisions are needed. In the past years, the therapeutic landscape of advanced non-small cell lung cancer (NSCLC) has changed impressively with the introduction of targeted therapies and immunotherapy next to chemotherapy. Treatment choices for advanced NSCLC are mainly guided by different tumor-related characteristics. However, in older patients treatment decisions are more complex because of the scarcity of data from large randomized studies in older patients and the heterogeneity of this population with regards to different geriatric domains such as functional status, comorbidity and polypharmacy. The present manuscript reviews available data for the different treatment options for older patients with NSCLC as well as the use of geriatric assessment as an evaluation and guidance tool. PMID- 30301661 TI - Comparison of intraperitoneal ropivacaine and bupivacaine for postoperative analgesia in dogs undergoing ovariohysterectomy. AB - OBJECTIVE: To compare postoperative analgesia following either intraperitoneal (IP) ropivacaine or bupivacaine in dogs undergoing ovariohysterectomy (OVH) in the scope of multimodal analgesia. STUDY DESIGN: Prospective, randomized, blinded clinical study. ANIMALS: A total of 45 privately owned dogs undergoing OVH, aged 37 +/- 28 months and weighing 11.3 +/- 4.5 kg. METHODS: Dogs were premedicated with acepromazine (0.05 mg kg-1) and morphine (0.5 mg kg-1) intramuscularly (IM). Anaesthesia was induced with alfaxalone and maintained with isoflurane in oxygen. Carprofen (4 mg kg-1) was injected subcutaneously after intubation. Dogs were randomly assigned to receive either bupivacaine (group B; 3 mg kg-1) or ropivacaine (group R; 3 mg kg-1) IP prior to complete closure of the linea alba. At 0.5, 1, 2, 4, 6 and 8 hours after extubation, sedation and postoperative pain were assessed, using the short form of the Glasgow Composite Pain scale (GCPS SF), a dynamic interactive visual analogue scale (DIVAS), and mechanical nociceptive threshold (MNT) measurement. Rescue morphine (0.2 mg kg-1) was administered in case of >= 5/20 or >= 6/24 in the GCPS-SF and/or >40 mm in the DIVAS. Parametric data were compared using the t test; nonparametric data were analysed with the two-sample Wilcoxon test (p < 0.05). RESULTS: The GCPS-SF score was significantly higher in group R at 8 hours. There was no other significant difference regarding sedation or analgesia between the groups. Rescue analgesia was administered to 15 dogs (R: 9/22; B: 6/22), with no significant difference between the groups. MNT values decreased in both groups at all time points when compared to baseline. No adverse effects were observed. CONCLUSIONS AND CLINICAL RELEVANCE: Ropivacaine or bupivacaine IP in combination with morphine IM and carprofen SC provided comparable postoperative analgesia in dogs after OVH for 6 hours. However, the anaesthetic protocol used did not prevent the administration of rescue analgesia in 41% of animals. PMID- 30301662 TI - Limited fluid volume resuscitation (LFVR) in severe shock unresponsive to initial fluid challenge: A pilot study in 10 cats. AB - OBJECTIVE: To evaluate the effect of limited fluid volume resuscitation (LFVR) administration in cats with severe shock that was unresponsive to initial conventional resuscitation (CR) with isotonic crystalloids. STUDY DESIGN: Clinical pilot study. ANIMALS: Ten client-owned cats with non-cardiogenic shock, unresponsive to CR. METHODS: After an initial ineffective CR with isotonic crystalloids (15-20 mL kg-1 in 15 minutes), LFVR was started. The animals were randomly assigned to one of two treatments: hypertonic saline alone (group HTS) or HTS and hydroxyethyl starch (HES) (group HTS/HES). A first bolus of HTS (2 mL kg-1) was administered to both groups, immediately followed by HES (2 mL kg-1) to group HTS/HES over 5-10 minutes and vital signs were re-evaluated. Additional boluses were administered, every 5-10 minutes, until stabilization (vital parameters, such as temperature, heart rate, respiratory frequency, quality of the pulse and sensorium within the physiological ranges). The time until stabilization (minutes), the volume of HTS and colloid administered and the effect of LFVR on vital parameters were determined. RESULTS: A mean +/- standard deviation (range) volume of 3 +/- 2 (2-6) mL kg-1 of hypertonic saline in group HTS and 4 +/- 2 (2-6) mL kg-1 of both hypertonic and colloidal solutions in group HTS/HES was administered. In six cats (60%), a single bolus of HTS alone (group HTS; n = 3/4) or in combination with HES (group HTS/HES; n = 3/6) was sufficient for stabilization. In the remaining four cases (40%), a second bolus was required. Stabilization occurred in 33 +/- 13 minutes (15-60 minutes). Of the 10 cats, six had a positive outcome (6-24 months follow-up) and the others died during hospitalization. CONCLUSIONS AND CLINICAL RELEVANCE: LFVR appears to be an efficacious treatment for feline shock and may be an alternative therapy for cats unresponsive to CR. Larger cross-sectional and prospective studies are needed to confirm these findings. PMID- 30301663 TI - Effect of benzodiazepines on the dose of alfaxalone needed for endotracheal intubation in healthy dogs. AB - OBJECTIVE: To evaluate the dose-sparing effect of midazolam or diazepam on the dose of alfaxalone required to achieve endotracheal intubation in premedicated dogs. STUDY DESIGN: Prospective, randomized, 'blinded', controlled clinical trial. ANIMALS: Ninety healthy dogs anaesthetized for elective surgery or diagnostic procedures. METHODS: Saline (0.1 mL kg-1), or midazolam or diazepam (0.2, 0.3, 0.4 or 0.5 mg kg-1) intravenously (IV) was randomly assigned; investigators were unaware of group designation. After premedication with IV acepromazine 0.01 mg kg-1 and methadone 0.2 mg kg-1, the degree of sedation was assessed. Alfaxalone (0.5 mg kg-1) was administered IV, followed by the assigned treatment. Further alfaxalone was administered until endotracheal intubation could be performed. Ease of endotracheal intubation, pulse rate and arterial blood pressure were assessed. General linear models were used to examine the effect of treatment drug and dose on induction dose of alfaxalone with Tukey's post hoc tests. Incidence of adverse reactions was assessed with chi-square tests. RESULTS: There were no significant differences between groups with regard to demographic data or sedation. Median (range) induction dose of alfaxalone in the saline group was 0.74 (0.43-1.26) mg kg-1 compared with 0.5 (0.46-0.75) mg kg 1 and 0.5 (0.42-1.2) mg kg-1 for the midazolam and diazepam groups, respectively. Midazolam 0.3 and 0.5 mg kg-1 (p = 0.005 and 0.044, respectively) and diazepam 0.4 mg kg-1 (p = 0.032) reduced the alfaxalone dose compared with saline. Adverse effects were not significantly different between groups. Midazolam 0.2, 0.3, 0.4 and 0.5 mg kg-1 (p < 0.044, p = 0.001, p = 0.007, p = 0.044, respectively) and diazepam 0.2 and 0.5 mg kg-1 (p = 0.025 and p = 0.025) improved intubation score compared with saline. CONCLUSION AND CLINICAL RELEVANCE: Midazolam 0.3 and 0.5 mg kg-1 and diazepam 0.4 mg kg-1 coadministered at anaesthetic induction allow alfaxalone dose reduction in healthy dogs. Use of benzodiazepines improved the ease of endotracheal intubation.

PMID- 30301665 TI - Sedative effect of intramuscular medetomidine with and without vatinoxan (MK 467), and its reversal with atipamezole in sheep. AB - OBJECTIVE: To evaluate the effect of the peripherally acting alpha2-adrenoceptor antagonist vatinoxan (MK-467) on the sedative properties of medetomidine (MED) when injected intramuscularly (IM) in the same syringe and on reversal of this sedation with atipamezole in sheep. STUDY DESIGN: Randomized, blinded, crossover experimental trial. ANIMALS: Eight healthy adult female sheep. METHODS: Sheep received MED (30 MUg kg-1 IM) alone or combined in the same syringe with vatinoxan (300 MUg kg-1 IM, MED+VAT) with a 2 week washout period. Atipamezole (150 MUg kg-1 IM) was administered 30 minutes later for reversal. Sedation was assessed using two sedation scores, a visual analog score and a descriptive scale before treatments (T0) and at intervals up to 5 hours thereafter. Pulse rate (PR) was counted at T0 and at 30 (T30) and 90 (T90) minutes. Rectal temperature was measured at T0 and T90 postinjection. Plasma samples were analyzed for drug concentrations at T30 and T90. RESULTS: The first signs of sedation were seen significantly earlier after MED+VAT (4.6 +/- 1.7 minutes versus 9.4 +/- 2.6 minutes after MED) and the sedation scores were significantly higher after MED+VAT than MED. All animals laid with head down 10.0 +/- 3.4 minutes after MED+VAT, whereas three MED animals did not become recumbent before atipamezole was administered. The plasma concentrations of dexmedetomidine were significantly higher at T30 (2.47 +/- 0.2 ng mL-1) and significantly lower at T90 (1.23 +/- 0.3 ng mL-1) with MED+VAT than with MED (1.19 +/- 0.8 and 1.83 +/- 0.4 ng mL-1, respectively). While no significant differences were observed between treatments in PR at T30, PR at T90 was significantly higher with MED+VAT than with MED. CONCLUSIONS AND CLINICAL RELEVANCE: When administered IM in the same syringe, vatinoxan hastened and intensified the initial sedative effects of MED and enhanced the sedation reversal by atipamezole. PMID- 30301666 TI - Development of Targeted siRNA Nanocomplexes to Prevent Fibrosis in Experimental Glaucoma Filtration Surgery. AB - RNAi induced by double-stranded small interfering RNA (siRNA) molecules has attracted great attention as a naturally occurring approach to silence gene expression with high specificity. The myocardin-related transcription factor/serum response factor (MRTF/SRF) pathway is a master regulator of cytoskeletal gene expression and, thus, represents a promising target to prevent fibrosis. A major hurdle to implementing siRNA therapies is the method of delivery, and we have, thus, optimized lipid-peptide-siRNA (LPR) nanoparticles containing MRTF-B siRNAs as a targeted approach to prevent conjunctival fibrosis. We tested 15 LPR nanoparticle formulations with different lipid compositions, surface charges, and targeting or non-targeting peptides in human conjunctival fibroblasts. In vitro, the LPR formulation of the DOTMA/DOPE lipid with the targeting peptide Y (LYR) was the most efficient in MRTF-B gene silencing and non cytotoxic compared to the non-targeting formulation. In vivo, subconjunctival administration of LYR nanoparticles containing MRTF-B siRNAs doubled bleb survival in a pre-clinical rabbit model of glaucoma filtration surgery. Furthermore, MRTF-B LYR nanoparticles reduced the MRTF-B mRNA by 29.6% in rabbit conjunctival tissues, which led to significantly decreased conjunctival scarring with no adverse side effects. LYR-mediated delivery of siRNA shows promising results to increase bleb survival and to prevent conjunctival fibrosis after glaucoma filtration surgery. PMID- 30301667 TI - miR-30 Family Reduction Maintains Self-Renewal and Promotes Tumorigenesis in NSCLC-Initiating Cells by Targeting Oncogene TM4SF1. AB - Increasing evidence indicates that tumor-initiating cells (TICs) are responsible for the occurrence, development, recurrence, and development of the drug resistance of cancer. MicroRNA (miRNA) plays a significant functional role by directly regulating targets of TIC-triggered non-small-cell lung cancer (NSCLC), but little is known about the function of the miR-30 family in TICs. In this study, we found the miR-30 family to be downregulated during the spheroid formation of NSCLC cells, and patients with lower miR-30a/c expression had shorter overall survival (OS) and progression-free survival (PFS). Moreover, transmembrane 4 super family member 1 (TM4SF1) was confirmed to be a direct target of miR-30a/c. Concomitant low expression of miR-30a/c and high expression of TM4SF1 correlated with a shorter median OS and PFS in NSCLC patients. miR 30a/c significantly inhibited stem-like characteristics in vitro and in vivo via suppression of its target gene TM4SF1, and then it inhibited the activity of the mTOR/AKT-signaling pathway. Thus, our data provide the first evidence that TM4SF1 is a direct target of miR-30a/c and miR-30a/c inhibits the stemness and proliferation of NSCLC cells by targeting TM4SF1, suggesting that miR-30a/c and TM4SF1 may be useful as tumor biomarkers for the diagnosis and treatment of NSCLC patients. PMID- 30301669 TI - Catheter Ablation of Ventricular Fibrillation. AB - Ventricular fibrillation (VF) is a common and life-threatening arrhythmia resulting in sudden cardiac death (SCD). Due to the inherent challenges of mapping VF in humans, the underlying mechanisms that initiate and sustain this common arrhythmia are still poorly understood. In high-risk patients and survivors of SCD, implantable cardioverter defibrillators (ICD) play a central role in treating VF episodes, however, ICDs do not prevent VF recurrences and patients remain at risk of electrical storm and multiple shocks that are often refractory to escalation of medical therapy. More recently, the utility of catheter ablation (CA) has extended to the treatment of VF storms. This review will focus on updates in elucidating the mechanism of VF leading into the role and indication of CA as a treatment strategy.

AB - The tumor microenvironment (TME) represents a complex interplay between different cellular components, including tumor cells and cancer stem cells (CSCs), with the associated stroma; such interaction promotes tumor immune escape and sustains tumor growth. Several experimental approaches for cancer therapy are focused on TME remodeling, resulting in increased antitumor effects. We previously demonstrated that the hyaluronan synthesis inhibitor 4-methylumbelliferone (4Mu) decreases liver fibrosis and induces antitumor activity in hepatocellular carcinoma (HCC). In this work, 4Mu, in combination with an adenovirus encoding interleukin-12 genes (AdIL-12), elicited a potent antitumor effect and significantly prolonged animal survival (p < 0.05) in an orthotopic HCC model established in fibrotic livers. In assessing the presence of CSCs, we found reduced mRNA levels of CD133+, CD90+, EpCAM+, CD44+, and CD13+ CSC markers within HCC tumors (p < 0.01). Additionally, 4Mu downregulated the expression of the CSC marker CD47+ on HCC cells, promoted phagocytosis by antigen-presenting cells, and, combined with Ad-IL12, elicited a potent cytotoxic-specific T cell response. Finally, animal survival was increased when CD133low HCC cells, generated upon 4Mu treatment, were injected in a metastatic HCC model. In conclusion, the combined strategy ameliorates HCC aggressiveness by targeting CSCs and as a result of the induction of anticancer immunity. PMID- 30301670 TI - Right Ventricular Function is Associated With Quality of Life in Patients With Systemic Lupus Erythematosus Associated Pulmonary Arterial Hypertension. AB - BACKGROUND: Right ventricular (RV) function has been identified as an important determinant of outcome in patients with pulmonary hypertension. We aimed to investigate the relationship between echocardiographic-derived RV function and health-related quality of life (HRQOL) in patients with systemic lupus erythematosus associated pulmonary arterial hypertension (SLE-APAH), and to identify the best echocardiographic parameter for evaluating RV function in these patients. METHODS: Sixty consecutive patients with SLE-APAH (all female, mean age 33.6+/-8.2years) were recruited from May 2013 to November 2014. Echocardiograph, right heart catheterisation, SLE disease activity index (SLEDAI), and functional status and SF-36 generic questionnaire were assessed. RESULTS: Echocardiograph derived RV systolic function was significantly correlated with haemodynamics (p<0.05), with tricuspid annular plane systolic excursion (TAPSE) showing the strongest correlation with pulmonary vascular resistance (R2=0.278, p<0.001) and cardiac index (R2=0.215, p<0.001). Patients with a TAPSE<17mm had a shorter 6 minute-walk-distance (6MWD), lower mixed venous oxygen saturation, and higher plasma N-terminal pro-brain natriuretic peptide (p<0.05). Patients with TAPSE <17mm had lower physical component summary (PCS) and mental component summary (MCS) scores than those with TAPSE >=17mm (35.5+/-13.2 vs. 55.0+/-15.5; 46.3+/ 15.3 vs. 64.8+/-18.8, respectively, all p<0.05). On multiple regression analysis, a TAPSE <17mm was independently related to lower PCS (beta -15.797, 95% confidence interval [CI] -24.746 to -6.848, p=0.001) and lower MCS (beta -12.887, 95% CI -24.018 to -1.755, p=0.024). CONCLUSIONS: TAPSE is a useful index for RV function assessment, and is associated with HRQOL in patients with SLE-APAH.

AB - The 12-lead electrocardiograph (ECG) is of critical importance both in the diagnosis of wide complex tachycardia and in the further classification, characterisation and management of ventricular arrhythmias. With its diligent application and interpretation, remarkable precision can be achieved in the localisation of the site of origin of ventricular arrhythmias and this may have major implications in the care of these patients. This review discusses the technical, anatomic and mechanistic basis of ECG interpretation in ventricular arrhythmias. PMID- 30301672 TI - Device-Related Thrombus After Left Atrial Appendage Occlusion With the Amulet Device. AB - BACKGROUND: Left atrial appendage occlusion (LAAO) is increasingly used for stroke prevention in patients with atrial fibrillation who are considered unsuitable for a lifelong oral anticoagulant regimen. Recently, a single-centre study reported device-related thrombus formation in 16.7% of patients treated with the second-generation Amulet device (St. Jude Medical, St. Paul, MN, USA), presenting a potential major safety concern. As "real-world" data on device related thrombus formation following LAAO with the Amulet occluder are scarce, we aimed to evaluate this outcome in a retrospective registry. METHODS: Clinical and tranosesophageal echocardiography data after LAAO with the Amulet in consecutive patients from three centres were collated. RESULTS: Among 38 patients (mean age 75.8 years), mean (standard deviation) CHA2DS2-VASc and HAS-BLED scores were 4.4 (1.2) and 3.4 (0.9), respectively. All patients underwent successful device placement without procedure-related adverse events. The antithrombotic regimen at discharge consisted of dual antiplatelet therapy (DAPT) in 27 patients (71.1%), single antiplatelet therapy in 10 patients (26.3%), and no antithrombotic therapy in one patient (2.6%). Device-related thrombus was observed in one patient (2.6%) despite DAPT regimen. The outcome of this patient was uncomplicated after adjustment of oral anticoagulant therapy. No patients presented with a thromboembolic event following LAAO during a mean (standard deviation) follow-up of 15 (5) months. CONCLUSIONS: In this retrospective study, device-related thrombus formation with the second-generation Amulet device was rare and occurred at a rate similar to that of the previous device. Importantly, no patient experienced a device-related thromboembolic event during follow-up. Larger real life studies are required to confirm the safety profile of this increasingly used device. PMID- 30301673 TI - Influence of Blood Count, Cardiovascular Risks, Inherited Thrombophilia, and JAK2 V617F Burden Allele on Type of Thrombosis in Patients With Philadelphia Chromosome Negative Myeloproliferative Neoplasms. AB - INTRODUCTION: Thrombosis is the most common complication in Philadelphia chromosome negative (Ph-) myeloproliferative neoplasms patients. PATIENTS AND METHODS: In a cohort of 258 Ph- myeloproliferative neoplasm patients, the difference between patients with and without thrombosis was analyzed according to genetic thrombophilia factors, JAK2 V617F status and burden allele, blood count, cardiovascular risk factors and age. Patients were also divided in polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) subgroups as well as by the type of thrombosis. RESULTS: Analysis of cardiovascular risk factors regarding arterial thrombosis showed that PV patients with thrombosis had higher incidence of diabetes (P = .030), ET patients more often had hypertension (P = .003) and hyperlipidemia (P = .005), while PMF patients had hyperlipidemia (P = .046) and at least one cardiovascular risk factor (P = .044). Moreover, leukocytes > 18 * 109/L and V617F burden allele > 25.7% were statistically significantly different in PV patients (P = .019 and borderline significant at P = .055, respectively), while in ET patients leukocytes > 9.2 * 109/L (P < .001) and age at diagnosis of > 55 years were statistically significantly different (P = .002). PMF patients with V617F burden allele <= 34.8% were more prone to thrombosis (P = .032). When comparing patients with and without venous thrombosis, cutoff value of V617F burden allele > 90.4% was significant for PV patients with thrombosis (P = .036), as was > 56.7% for PMF patients with thrombosis (P = .046). Platelets <= 536 * 109/L and age at diagnosis > 54 years showed statistically significant difference for ET patients with thrombosis (P = .015 and P = .041, respectively). CONCLUSION: On the basis of our results, a new scoring system for thrombosis risk in PV could be made, while PMF prognostic model may be expanded for better recognition of potential thrombotic risk factors. PMID- 30301674 TI - Novel tacrine-pyridinium hybrid reactivators of organophosphorus-inhibited acetylcholinesterase: Synthesis, molecular docking, and in vitro reactivation study. AB - First-line medical treatment against nerve agents consists of co-administration of anticholinergic agents and oxime reactivators, which reactivate inhibited AChE. Pralidoxime, a commonly used oxime reactivator, is effective against some nerve agents but not against others; thus, new oxime reactivators are needed. Novel tacrine-pyridinium hybrid reactivators in which 4-pyridinealdoxime derivatives are connected to tacrine moieties by linear carbon chains of different lengths (C2-C7) were prepared (Scheme 1, 5a-f). Their binding affinities to electric eel AChE were tested because oximes can inhibit free AChE, and the highest AChE activity (95%, 92%, and 90%) was observed at 1 MUM concentrations of the oximes (5a, 5b, and 5c, respectively). Based on their inhibitory affinities towards free AChE, 1 MUM concentrations of the oxime derivatives (5) were used to examine reactivation of paraoxon-inhibited AChE. Reactivation ability increased as the carbon linker chains lengthened (n = 2-5), and 5c and 5d showed remarkable reactivation ability (41%) compared to that of 2 PAM (16%) and HI-6 (4%) against paraoxon-inhibited electric eel AChE at 1 MUM concentrations. Molecular docking simulation showed that the most stable binding free energy was observed in 5c at 73.79 kcal?mol-1, and the binding mode of 5c is acceptable for the oxygen atom of oximate to attack the phosphorus atom of paraoxon and reactivate paraoxon-inhibited eel AChE model structure. PMID- 30301675 TI - Identification of inhibitors of the E. coli chaperone SurA using in silico and in vitro techniques. AB - SurA is a gram-negative, periplasmic chaperone protein involved in the proper folding of outer membrane porins (OMPs), which protect bacteria against toxins in the extracellular environment by selectively regulating the passage of nutrients into the cell. Previous studies demonstrated that deletion of SurA renders bacteria more sensitive to toxins that compromise the integrity of the outer membrane. Inhibitors of SurA will perturb the folding of OMPs, leading to disruption of the outer membrane barrier and making the cell more vulnerable to toxic insults. The discovery of novel SurA inhibitors is therefore of great importance for developing alternative strategies to overcome antibiotic resistance. Our laboratory has screened over 10,000,000 compoundsin silicoby computationally docking these compounds onto the crystal structure of SurA. Through this screen and a screen of fragment compounds (molecular weight less than 250 g/mol), we found twelve commercially readily available candidate compounds that bind to the putative client binding site of SurA. We confirmed binding to SurA by developing and employing a competitive fluorescence anisotropy based binding assay. Our results show that one of these compounds, Fmoc-beta-(2 quinolyl)-d-alanine, binds the client binding site with high micromolar affinity. Using this compound as a lead, we also discovered that Fmoc-l-tryptophan and Fmoc l-phenylalanine, but not Fmoc-l-tyrosine, bind SurA with similar micromolar affinity. To our knowledge, this is the first report of a competitive fluorescence anisotropy assay developed for the identification of inhibitors of the chaperone SurA, and the identification of three small molecules that bind SurA at its client binding site. PMID- 30301676 TI - Discovery of a potent orally bioavailable retinoic acid receptor-related orphan receptor-gamma-t (RORgammat) inhibitor, S18-000003. AB - The retinoic acid receptor-related orphan receptor-gamma-t (RORgammat) is the master transcription factor responsible for regulating the development and function of T-helper 17 (Th17) cells, which are related to the pathology of several autoimmune disorders. Therefore, RORgammat is an attractive drug target for such Th17-mediated autoimmune diseases. A structure-activity relationship (SAR) study of lead compound 1 yielded a novel series of RORgammat inhibitors, represented by compound 6. Detailed SAR optimization, informed by X-ray cocrystal structure analysis, led to the discovery of a potent orally bioavailable RORgammat inhibitor 25, which inhibited IL-17 production in the skin of IL-23 treated mice by oral administration. PMID- 30301677 TI - Preventative Health and Risk Behaviors Among Adolescent Girls With and Without Family Histories of Breast Cancer. AB - PURPOSE: To compare health behaviors (smoking, alcohol use, fruit and vegetable intake, and exercise frequency) and breast self-exam (BSE) between girls with breast cancer family history (BCFH+) and without (BCFH-) and assess associates of behaviors across all girls. METHODS: A total of 208 BCFH+ girls (11-19years old), with first- or second-degree relatives with breast cancer or a mother with a BRCA1/2 mutation, and 112 BCFH- peers reported their health behaviors, beliefs, and psychosocial function. RESULTS: Despite higher BCFH+ girls' greater perceived breast cancer risk, there were no differences between BCFH+ and BCFH- girls on diet, exercise, alcohol initiation, or BSE. BCFH+ girls were slightly more likely to report trying cigarettes (11% vs. 5%, p = .04). In multivariable models with all girls, categorical associations with behaviors included the following: developmental and demographic factors with smoking, alcohol, diet, and exercise; family breast cancer history and experience with smoking, alcohol, and diet; psychosocial factors with smoking; girls perceptions of cancer controllability and mother support for health behaviors with alcohol, diet, exercise, and BSE; and mother behaviors with diet. CONCLUSIONS: Adolescent girls from BCFH+ families reported similar health behaviors to BCFH- peers, signaling that they are not translating their higher perceived risk into cancer controlbehaviors. Both uncontrollable (i.e., breast cancer experiences) and modifiable factors relate to health behaviors and warrant further investigation. Results indicate that interventions with teens and parents that target modifiable variables such as controllability perceptions, maternal modeling, and communication may relate to better health behaviors and reduced future breast cancer risk. PMID- 30301678 TI - Suicide mortality trends in Spain, 1980-2016. AB - OBJECTIVES: To analyse changes in suicide mortality trends in Spain between 1980 2016 using joinpoint regression models. METHODS: Mortality data were obtained from the INE. For each gender, age-group-specific and standardised (overall and truncated) rates (ASR) were calculated by the direct method (using the European standard population). The joinpoint analysis was used to identify the best fitting points where a statistically significant change in the trend occurred. RESULTS: Age adjusted mortality rates due to suicide in men was 9.8/100,000 males in 1980 and 11.8 in 2016, with an average annual increase of .8%. In women, the rates increased by 1.0% per year from 2.7 women per 100,000 in 1980 to 3.7 in 2016. The joinpoint analysis identified three turning points in the rates for both men (1986, 2000 and 2010) and women (1986, 2004 and 2010), which identify changes in the trend. In the period 2010-2016 the rates increase in women while in men the rates remain stable. CONCLUSIONS: Our work shows a marked increase in mortality by suicide in Spanish women (2010-2016) while in men the rates remain stable. Little is known about the determinants of the increase and, therefore, more studies are needed. PMID- 30301679 TI - Advancing the Science of Healthcare Service Delivery: The NHLBI Corporate Healthcare Leaders' Panel. AB - There is a growing gap between available science and evidence and the ability of service providers to deliver high-quality care in a cost-effective way to the entire population. We believe that the chasm between knowledge and action is due to a lack of concerted effort among all organizations that deliver health care services across the life span of patients. Broad participation is needed and necessitates a far more explicit and concerted public-private partnership focused on large-scale transformation. In this context, the National Heart, Lung, and Blood Institute convened a panel made up of leaders of corporate health care entities, including academic health centers, and government agency representatives to inform contemporary strategic partnerships with health care companies. This article provides insights from the meeting on how to execute a transformative innovation research agenda that will foster improvements in health care service delivery by leveraging the translation of biomedical research evidence in real-world settings. PMID- 30301680 TI - Global Atlas of Cardiovascular Disease 2000-2016: The Path to Prevention and Control. PMID- 30301681 TI - Obesity, dynapenia and high cardiovascular risk co-exist in post-liver transplant setting: results of a cross-sectional study. AB - BACKGROUND: Cardiovascular disease is a major cause of death in post-liver transplantation (LT). The aim of this study was to evaluate LT patients as to the carotid intima-media thickness (CIMT) and its association with nutritional status, dietary intake, metabolic profile and cardiovascular risk factors. METHODS: In this cross-sectional study, adult patients with more than 12 months of post-transplant follow-up underwent clinical, laboratory, functional and nutritional evaluation by 3-day-diet-record, anthropometry and dynamometry. CIMT was evaluated by Doppler ultrasonography. RESULTS: Sixty-nine post-LT patients [males 61%, median of age 59 (51-64) years were included; median time post-liver transplantation 2.8 (1.4-6.3) years]. High prevalence of malnutrition was found (45% of arm muscle area < p15 and 71% of handgrip strength < p30). Excess weight was present in 72% of patients, body mass index >= 30 kg/m2 in 35% and metabolic syndrome in 51%. Abnormal CIMT was found in 54% of the sample. Patients with abnormal CIMT presented higher cardiovascular risk Score, LDL cholesterol, higher prevalence of high-sensitive C-reactive protein >= 1 mg/L and higher intake of saturated and trans fatty acids (P < 0.05 for all). CONCLUSIONS: Abnormal IMT was commonly found in LT patients presenting at the same time with overweight and dynapemia. These results were associated with higher LDL-cholesterol levels, high sensitive C-reactive protein >= 1 mg/L and higher intake of saturated and trans fatty acids. Preventive measures, including dietary advice, are required for all post-liver transplantation patients to minimize cardiovascular risk. PMID- 30301682 TI - Comparing algorithms for composite measures of intra-disease multiple medication adherence: The case of diabetes. AB - BACKGROUND: Adherence to multiple medications (i.e., separate dosage forms) intended for a disease can be measured by different single estimators, termed as composite estimators of intra-disease multiple medication adherence: 80% days covered (a) by at least one medication ("at least one"); (b) by both medications ("both"); (c) by each medication measured separately ("all"); and (d) computing an average of the individual medication adherence estimates ("average"). OBJECTIVES: (a) Assess different composite adherence estimators regarding their ability to predict healthcare utilization; (b) compare and contrast composite estimators. METHODS: Using MarketScan 2002-2003 data, 6043 nonelderly patients who filled separate prescriptions of sulfonylurea [SU] and thiazolidinedione [TZD] were identified. Adherence was measured by the proportion of days covered (PDC) over periods of 90 days, 30 days, and cumulatively over such periods. Cox proportional hazards models analyzed all-cause and diabetes-related emergency room (ER) visits as the outcome variables. RESULTS: All composite measures predicted hazards of all-cause or diabetes ER visits (P < 0.001) and each measure showed statistically significant discriminatory power (concordance statistics from 0.55 to 0.58). Cox regression was performed multiple times in which composite estimators measured on a continuous scale (e.g., 'average') were dichotomized using several cut-points. In the majority of cases (<=3 out of 8 times in analyses of ER outcomes), optimal results did not occur when the dichotomization cut-point was set at 80%. CONCLUSIONS: Each composite estimator showed the fundamental quality of a good measure. Although 'average' and 'all' approaches offer ease of measurement, there was no clear trend in superiority of one measure over the others. Clinical and practical considerations should dictate the choice of measure. PMID- 30301683 TI - Clinical and economic considerations based on persistency with a novel insulin delivery device versus conventional insulin delivery in patients with type 2 diabetes: A retrospective analysis. AB - OBJECTIVE: Insulin is one of the most efficacious treatments for hyperglycemia; however, adherence to insulin therapy is poor, impacting its efficacy. Thus, the objectives of this study were to determine if persistent use of a new insulin delivery option, V-Go, improved clinical outcomes and secondly compare clinical and economic outcomes between persistent use of V-Go and conventional insulin delivery (CID). METHODS: A retrospective review of an outpatient clinic's records was performed. Patients initiating V-Go with documented persistent use of V-Go or resumed persistent use of CID after short-term V-Go use were included (>=5 months of persistency). Baseline data and a total of two post-V-Go or CID initiation visits were examined for clinical and economic outcomes. Cost-effectiveness of each therapy was calculated by dividing the mean cost difference (baseline to office visit 2) by the mean change in A1c (baseline to office visit 2). RESULTS: V-Go persistent patients had a significant decrease in A1c (-1.42; p < 0.001). Between baseline and office visit two, they required less insulin units/day and units/kg and had significantly lower A1c, insulin units/day, insulin units/kg, and 30-day insulin costs than CID patients. V-Go persistent patients had a lower incremental cost by $695.61 per 1% change in A1c compared to CID persistent patients. CONCLUSIONS: Utilization of a new insulin delivery option resulted in improved clinical outcomes compared to CID and was more cost-effective. Clinicians and health plans should consider the use of new insulin delivery options for the management of patients with diabetes on insulin therapy to promote persistence. PMID- 30301684 TI - Comparison of outcomes in women and men following carotid interventions in the Washington state's Vascular Interventional Surgical Care and Outcomes Assessment Program. AB - BACKGROUND: The benefit for carotid endarterectomy (CEA) to prevent a potential stroke has been shown to be less beneficial for women compared with men and the risk of carotid stenting (CAS) is higher in women than men. We hypothesized that a community-based Washington state registry data would also reveal increased morbidity and mortality for women undergoing carotid interventions. METHODS: Deidentified data for CEA and CAS between 2010 and 2015 were obtained from 19 hospitals participating in the Washington State Vascular-Interventional Surgical Care and Outcomes Assessment Program. Data analysis compared in-hospital composite outcome of stroke and mortality from CEA and CAS between women and men. RESULTS: Over the study period, 3704 individuals underwent CEA (n = 2759; 49.5% symptomatic) and CAS (n = 945; 60.9% symptomatic). Women accounted for 39.5% of the cohort. Women were slightly younger than men (70.0 +/- 10.2 vs 71.0 +/- 9.6 years respectively; P < .01), less likely to be smokers (70.1% vs 75.6%; P < .01), and less likely to have a diagnosis of coronary artery disease (32.9% vs 46.5%; P < .01). Fewer women underwent CEA for symptomatic carotid disease (46.1% vs 51.8%; P < .01). There were no statistically significant differences in the postoperative in-hospital stroke and mortality among women and men undergoing CEA (asymptomatic, 0.8% vs 1.4% [P = .36]; symptomatic, 1.8% vs 2.2% [P = .58]) and CAS (asymptomatic, 1.4% vs 2.2% [P = .56]; symptomatic, 4.6% vs 2.5% [P = .18]). Hospital duration of stay and discharge disposition were similar for women and men. A subanalysis of the octogenarian cohort undergoing CAS demonstrated a substantial increase in-hospital stroke and mortality among women and men (11.6% [CAS] vs 2.2% [CEA]; P = .024). CONCLUSIONS: In the Washington state Vascular Interventional Surgical Care and Outcomes Assessment Program registry, hospital composite outcome of stroke and mortality following carotid interventions from 2010 to 2015 were noted to be similar for women and men. The notable exception to this finding was observed in subcohort of women undergoing CAS for symptomatic carotid disease at age 80 years or older. These findings should be taken into account when risk stratifying patients for carotid interventions. PMID- 30301685 TI - Comparison of one-stage and two-stage upper arm brachiobasilic arteriovenous fistula in the Vascular Quality Initiative. AB - OBJECTIVE: An upper arm brachiobasilic arteriovenous fistula (BBAVF) is a reliable autogenous hemodialysis access created with a one-stage or two-stage technique. Although both techniques are variably used, the optimal approach is uncertain. In this study, we compared the outcomes of one-stage and two-stage BBAVF procedures. METHODS: We identified 2648 patients who had received BBAVFs within the Vascular Quality Initiative data set (2010-2016) and compared those created using the one-stage and two-stage technique. The primary outcome measures were primary and secondary patency rates at 12 months. Other outcomes assessed were wound infection, steal, and swelling at 3 months. The log-rank test was used to evaluate patency by Kaplan-Meier analysis. Cox proportional hazards models were used to examine the adjusted association between surgical technique and outcomes. RESULTS: There were 1234 (47%) one-stage and 1414 (53%) two-stage BBAVFs in the study cohort, including 1848 (70%) patients who were on dialysis at the time of surgery and 1795 (68%) patients with a history of previous access. Patients who underwent a one-stage BBAVF were more likely to be male (54% vs 45%; P < .001), to be white (60% vs 41%; P < .001), and to have a history of coronary artery disease (22% vs 17%; P = .001). Patients undergoing one-stage BBAVFs have larger vein diameters (4.1 vs 3.4 mm; P < .001) and have the procedure in an inpatient setting (21% vs 13%; P < .001) compared with patients undergoing a two stage procedure. The 12-month primary patency rate was higher for the one-stage BBAVF (49.1% vs 40.4%; P = .005), although the secondary patency rate was comparable (80.0% vs 77.9%; P = .54). Postoperative bleeding (4% vs 1.5%; P < .001), wound infection (1.01% vs 0.4%; P = .047), and arm swelling (2.1 % vs 0.8%; P = .006) were higher for one-stage BBAVFs. In multivariable analysis, although loss of primary patency at 12 months (adjusted hazard ratio [aHR], 1.12; 95% confidence interval [CI], 0.97-1.30; P = .12) and 3-month wound infection (aHR, 0.42; 95% CI, 0.14-1.25, P = .12) were similar between the two approaches, the risk of 3-month arm swelling was significantly lower for two-stage BBAVFs (aHR, 0.35; 95% CI, 0.16-0.77; P = .009). CONCLUSIONS: Whereas surgeons were more likely to perform a two-stage BBAVF in patients with a history of previously failed access and smaller basilic vein, our data show no difference in primary or secondary patency of one-stage and two-stage BBAVFs at 12 months. PMID- 30301686 TI - Patient satisfaction and chronic illness are predictors of postendovascular aneurysm repair surveillance compliance. AB - OBJECTIVE: Although lifelong surveillance is recommended by the Society for Vascular Surgery for patients undergoing endovascular aneurysm repair (EVAR) reported that compliance with long-term follow-up has been poor. We sought to identify factors that predict compliance with EVAR surveillance through analysis of patient variables and post-EVAR questionnaire results. METHODS: We analyzed 28 patient variables gathered from our computerized registry, patient charts, and phone questionnaires of patients who underwent EVAR between January 1, 2010, and December 31, 2014. These factors included patient demographics, education, postoperative complications, satisfaction with vascular surgery care, transportation mode, distance to our medical center, and living situation. Compliance was defined as a patient who underwent the most recent recommended follow-up surveillance study within the prescribed timeframe. Post-EVAR surveillance protocol consisted of office evaluation and duplex ultrasound examination performed in our accredited noninvasive vascular laboratory at 1 week, 6 months, then annually. Computed tomography angiography was obtained only if duplex ultrasound examination suggested endoleak, sac enlargement of more than 5 mm, or a failing limb. RESULTS: Of 144 patients who underwent EVAR during this time period, 89 patients (62%) were compliant with the most recent recommended follow-up study. One hundred two patients completed the questionnaire or their families did if patients died or were incapacitated. Of those, 80 were compliant with follow-up and 22 were not. Based on the questionnaires of these 102 patients, estimated compliance at 3 years after EVAR was 69.6 +/- 6.0% based on Kaplan-Meier analysis. In the compliant vs noncompliant groups, the estimated 3 year survival rate was 93.2 +/- 3.4% vs 52.4 +/- 12.7%, respectively (P < .001), and the estimated 5-year survival rate was 83.1 +/- 6.4% vs 34.4 +/- 13.4%, respectively (P < .001), respectively. However, none of the mortalities observed in the noncompliant group were aneurysm related. Adverse neurologic events after EVAR demonstrated a trend predicting noncompliance after 5 years based on multivariate Cox regression analysis (hazard ratio [HR], 2.57; 95% confidence interval [CI], 0.95-6.90; P = .062). Patient dissatisfaction with their vascular surgeon and hospital care predicted noncompliance with recommended postoperative surveillance (HR, 5.0; 95% CI, 1.52-16.7; P = .008). College education or higher was associated with compliance (HR, 0.28; 95% CI, 0.06-1.23; P = .092). No other variables, including postoperative complications or distance from the hospital, predicted follow-up noncompliance. CONCLUSIONS: Patient satisfaction with their vascular surgeon and hospital experience predicted compliance with post-EVAR surveillance regardless of postoperative complications. Noncompliant patients had decreased survival, but mortality and surveillance noncompliance were likely due to disabling chronic disease. PMID- 30301687 TI - Aortic neck dilation is not associated with adverse outcomes after fenestrated endovascular aneurysm repair: Midterm results from an investigational device exemption clinical trial. AB - OBJECTIVE: Long-term outcomes after endovascular aneurysm repair (EVAR) are threatened by aortic neck dilation (AND), graft migration, and subsequent endoleak development. The aim of this study was to determine the rate of AND and the occurrence of endoleaks after fenestrated EVAR of juxtarenal aneurysms with physician-modified endovascular grafts (PMEGs). METHODS: The study included 77 patients presenting with asymptomatic and ruptured juxtarenal abdominal aortic aneurysms treated with PMEGs who received radiologic follow-up. Analysis of computed tomography images took place on a three-dimensional workstation (TeraRecon, San Mateo, Calif). Aortic neck diameter was measured before and after EVAR at the lowest patent renal artery outer wall to outer wall. Significant AND was defined as >3-mm increase between baseline and follow-up, and sac regression >5 mm was considered significant. The patient's 1-month initial postoperative computed tomography measurement was considered baseline. The rate of AND was measured by comparing the baseline measurement with measurements at 6 months, 12 months, and annually thereafter up to 4 years. RESULTS: In this cohort of patients, 75% were men with a mean age of 74 +/- 7.9 years. Median preoperative aneurysm size was 62 (57-73) mm, and median follow-up was 12 (3.5-30) months. Mean endograft oversizing was 17% +/- 12.5%, and mean seal zone length was 41 +/- 11 mm. At 1-year follow-up, the median aortic neck increase was 1.7 (0-3) mm. Maximum aneurysm size decreased dramatically during the first postoperative year, with significant sac regression in 65% of the patients. Aortic neck diameter at 1 year did correlate positively with the percentage of device oversizing. No other correlations were found. During the 4-year follow-up, there were no cases of type IA endoleaks. CONCLUSIONS: AND does not influence outcome after endovascular repair of juxtarenal aneurysms using PMEGs. These midterm results support the applicability of PMEGs in juxtarenal aneurysm repair. PMID- 30301688 TI - The role of ascending aortic size in outcomes of patients with uncomplicated acute type B aortic dissection. AB - OBJECTIVE: Recent studies demonstrate that uncomplicated acute type B aortic dissection (uATBAD) patients with enlarged descending thoracic aortic diameters are at high risk for development of complications. This study aimed to determine the association of maximum ascending aortic diameter and area and outcomes in patients with uATBAD. METHODS: All patients admitted with uATBAD from June 2000 to January 2015 were reviewed, and those with available imaging were included. All measurements were obtained by a specialized cardiovascular radiologist, including the maximum ascending aortic diameter and area. Outcomes, including the need for intervention and mortality, were tracked over time. Data were analyzed by stratified Kaplan-Meier and multiple Cox regression analyses using SAS 9.4 software (SAS Institute, Cary, NC). RESULTS: During the study period, 298 patients with uATBAD were admitted, with 238 having available computed tomography and 131 having computed tomography angiography imaging and adequate follow-up available for analysis. The cohort had an average age of 60.96 +/- 13.4 years (60% male, 53% white). Ascending aortic area >12.1 cm2 and ascending aortic diameter >40.8 mm were associated with subsequent arch and proximal progression necessitating open ascending aortic repair (P < .027 and P < .033, respectively). Ascending diameter >40.8 mm predicted lower intervention-free survival (P = .01). However, it failed to predict overall survival (P = .12). Ascending aortic area >12.1 cm2 predicted lower intervention-free survival (P = .005). However, this was not predictive of mortality (P = .08). Maximum aortic diameter along the length of the aorta >44 mm persisted as a risk factor for mortality (P < .001). Neither maximum ascending aortic diameter >40.8 mm (hazard ratio [HR], 1.09; 95% confidence interval [CI], 0.42-2.83; P = .85) nor area >12.1 cm2 (HR, 0.992; 95% CI, 0.38-2.61; P = .99) significantly predicted mortality when controlling for maximum aortic diameter along the length of the aorta >44 mm (HR, 7.34; 95% CI, 2.3-23.41; P < .001), diabetes mellitus (HR, 6.4; 95% CI, 2.17-18.93; P < .001), age (HR, 1.06/y; 95% CI, 1.03-1.10; P < .001), history of stroke (HR, 5.03; 95% CI, 1.52-16.63; P = .008), and syncope on admission (HR, 21.11; 95% CI, 2.3 193.84; P = .007). Ascending aortic diameter >40.8 mm (HR, 2.01; 95% CI, 1.03 3.95; P = .04) and maximum ascending aortic area >12.1 cm2 (HR, 1.988; 95% CI, 1.02-3.87; P = .04) on admission persisted as predictors of decreased intervention-free survival after controlling for maximum aortic diameter along the length of the aorta >44 mm (HR, 3.142; 95% CI, 1.47-6.83; P < .004), syncope on admission (HR, 26.3; 95% CI, 2.81-246; P < .004), and pleural effusion on admission (HR, 3.02; 95% CI, 1.58-5.77; P < .001). CONCLUSIONS: uATBAD patients with ascending aortic area >12.1 cm2 or maximum ascending aortic diameter >40.8 mm are at high risk for development of subsequent arch and proximal progression and may require closer follow-up or earlier intervention. Ascending aortic size (diameter and area) is predictive of decreased intervention-free survival in patients with uATBAD. PMID- 30301689 TI - In-hospital versus postdischarge major adverse events within 30 days following lower extremity revascularization. AB - OBJECTIVE: Studies using hospital discharge data likely underestimate postoperative morbidity and mortality after lower extremity revascularization because they fail to capture postdischarge events. However, the degree of underestimation and the timing of postdischarge complications are not well characterized. METHODS: We used the American College of Surgeons National Surgical Quality Improvement Program procedure-targeted vascular databases from 2011 to 2015 to tabulate 30-day adverse events (in hospital and after discharge) for lower extremity bypass (LEB) and percutaneous vascular interventions (PVIs) performed for claudication and chronic limb-threatening ischemia (CLTI). RESULTS: A total of 14,125 patients underwent lower extremity revascularization, 8909 patients (63%) with LEB and 5216 (37%) with PVI. For CLTI, total 30-day mortality was similar between PVI and LEB (2.3% vs 2.1%; P = .61), but in-hospital deaths only accounted for 43% of PVI mortality and only 65% of LEB mortality (P <= .001). Major adverse cardiac events occurred in 2.9% of PVI patients and 4.6% of LEB patients (P < .001), with postdischarge events accounting for 37% of PVI events and 18% of LEB (P <= .001). Although the 30-day reoperation rates were 14% for PVI and 18% for LEB (P < .001), almost one-half occurred after discharge (PVI 46% vs LEB 44%; P = .55). Any postoperative major adverse events (MAEs) occurred in 22% of patients after PVI and 31% after LEB, with more than one-half occurring after discharge (PVI 56% vs LEB 53%; P = .17). For claudicants, total 30-day mortality was 0.4% for PVI and 0.7% for LEB (P = .32), with the vast majority of events occurring after discharge (PVI 90% vs LEB 50%; P = .049). The 30-day reoperation rates were 5.2% for PVI and 8.0% for LEB (P < .001), with more than one-half occurring after discharge (PVI 63% vs LEB 53%; P = .09). Any MAEs occurred in 7.0% of patients after PVI and 17% after bypass, with the majority occurring after discharge (PVI 65% vs LEB 63%; P = .66). CONCLUSIONS: Most MAEs occur less frequently after PVI than LEB. However, a significant number of major of adverse events after lower extremity revascularization occur after leaving the hospital, especially after PVI, which may overestimate its benefits compared with LEB if only in-hospital data are evaluated. These data demonstrate the importance of reporting 30-day rather than in-hospital outcomes when evaluating postoperative adverse events. PMID- 30301690 TI - Outcomes associated with a transcarotid artery revascularization-centered protocol in high-risk carotid revascularizations using the ENROUTE neuroprotection system. AB - OBJECTIVE: This investigation describes the perioperative and early follow-up results associated with transcarotid artery revascularization (TCAR) in patients not participating in the Safety and Efficacy Study for Reverse Flow Used During Carotid Artery Stenting Procedure II (ROADSTER-2) registry using the ENROUTE neuroprotection system (ENPS; Silk Road Medical, Sunnyvale, Calif). METHODS: A retrospective review was performed capturing all TCAR/ENPS procedures in patients deemed to be at high risk for complications after traditional carotid endarterectomy. All patients enrolled in the ROADSTER-2 registry were excluded, leaving only those treated outside trial regulations for analysis. Preoperative demographics, intraoperative variables, and perioperative and follow-up outcomes were abstracted and reported herein. RESULTS: From December 2015 to January 2018, there were 75 carotid arteries treated at our institution. All interventions were performed on carotid arteries that were symptomatic with >=50% stenosis (46.7%) or asymptomatic with >=80% stenosis (53.3%) by duplex ultrasound and computed tomography angiography. Technical success in our series was 97.3% (73/75), with treatment failures attributed to one case of common carotid artery dissection and another secondary to stent maldeployment in the external carotid artery. Perioperative (30-day) ipsilateral stroke rate was 2.7% (n = 2), myocardial infarction incidence was 0%, and mortality rate was 2.7% (n = 2). We did not observe any cranial nerve injuries. After a mean follow-up of 8.0 +/- 6.7 months, no carotid stents required reintervention. However, we noted one instance of minor (<50%) in-stent stenosis and one asymptomatic stent thrombosis. One additional ipsilateral stroke was observed on follow-up, probably from a cardiac source. CONCLUSIONS: We report that dynamic reverse-flow TCAR using the ENPS continues to be safe, feasible, and efficacious with minimal risks of postoperative stroke, myocardial infarction, and mortality outside of ROADSTER-2 regulations. PMID- 30301691 TI - Burnout, depression, perceived stress, and self-efficacy in vascular surgery trainees. AB - OBJECTIVE: Burnout is a work-related syndrome involving emotional exhaustion, depersonalization, and a sense of reduced personal accomplishment that has become prevalent in all levels of medical training. We sought to understand factors associated with burnout identified in vascular surgery trainees. METHODS: An anonymous electronic survey consisting of demographic and programmatic information as well as validated scales for burnout, depression, perceived stress, self-efficacy, and social support was given to all vascular surgery trainees in the United States. Univariate and multivariate analyses were used to compare responses. Residents were grouped into quartiles based on burnout level, and predictors of burnout were determined. RESULTS: Of the 514 invitations sent, 177 (34%) respondents completed the survey. Trainees in the highest quartile of burnout were more likely to have moderate to severe depression (40% vs 4%; P < .01), higher perceived stress score (odds ratio [OR], 1.3; P < .01), lower social support (OR, 0.89; P < .01), and lower self-efficacy (OR, 0.76; P < .01), and they were less likely to reconsider vascular surgery as a career if given the chance to do it over (chi2 = 20; P < .01). Trainees without a self-identified mentor were significantly more likely to report burnout (chi2 = 15; P < .01). In addition, trainees who reported more frequent 80-hour work infractions each month (3.6 vs 2.3; P < .01) and those without access to programmatic social events (chi2 = 11; P < .01) had higher levels of burnout. In contrast, trainees with the lowest quartile of burnout scores reported lower depression (OR, 0.43; P < .01), lower stress (OR, 0.63; P < .01), more social support (OR, 0.1.2; P < .01), higher self-efficacy (OR, 1.2; P < .01), and fewer work week violations each month (2.3 vs 2.9; P = .04). Lower burnout scores were associated with program mentorship (chi2 = 7.3; P < .01), program-sponsored social events (chi2 = 8.7; P < .01), and being more likely to choose vascular surgery again if given the chance (chi2 = 6.3; P < .01). Highest burnout scores did not correlate with sex (chi2 < .01; P = 1), age (32 years vs 32 years; P = .65), marital status (chi2 < .01; P = 1), proximity to family (OR, 1.2; P = .26), alcohol consumption (chi2 = 0.23; P = .63), postgraduate year (OR, 1.1; P = .47), number of prior program graduates (OR, 0.95; P = .73), use of physician extenders in the program (OR, 0.93; P = .74), or total debt (OR, 1.0; P = .63). Similarly, there were no significant associations with these variables among trainees with the lowest quartile of burnout scores. On multivariate analysis, higher depression (OR, 1.6; P < .01) and higher perceived stress (OR, 1.2; P < .01) were associated with higher burnout scores, and lower burnout scores were associated with lower perceived stress (OR, 0.67; P < .01). CONCLUSIONS: Burnout in vascular surgery trainees is associated with higher levels of depression and perceived stress and lower levels of social support and self-efficacy. The addition of programmatic social events, limiting 80-hour work week violations, and addition of formal mentoring programs may decrease levels of burnout. PMID- 30301692 TI - Endovascular aneurysm repair in patients over 75 is associated with excellent 5 year survival, which suggests benefit from expanded screening into this cohort. AB - BACKGROUND: Endovascular aneurysm repair (EVAR) has decreased the perioperative mortality for patients undergoing abdominal aortic aneurysm repair and has increased the rates of elective aneurysm repair in the elderly. However, Medicare will not cover abdominal aortic aneurysm screening for beneficiaries over 75 years of age. Consequently, abdominal aortic aneurysm treatment in this population depends on incidental detection. Targeted coverage for screening in this population, however, might be beneficial for a subgroup of patients. METHODS: To identify a subset of elderly patients who would potentially benefit from an expanded screening policy, we reviewed all patients greater than 75 years old undergoing elective EVAR in the Vascular Quality Initiative between 2003 and 2016. We used Cox regression with multivariable fractional polynomials to construct a risk model for 5-year survival in elderly patients to identify a subpopulation who might benefit the most from screening and performed internal validation using the bootstrapping technique. RESULTS: We identified 10,676 patients greater than 75 years old undergoing elective EVAR. Although perioperative mortality varied with age, it was only 2.1% in the oldest group of patients (>85 years). Significant predictors included in our final risk model for 5-year survival in the elderly included age, aortic diameter, hemoglobin, current smoking, white race, body mass index, renal function, congestive heart failure, statin use, chronic obstructive pulmonary disease, and ejection fraction. The risk model produced risk scores ranging from a possible -2 to 33. The mean and median risk score were 6.9 and 6.0, respectively, with a right skew. We categorized the risk scores into four groups: -2 to 4 points, 5-8 points, 9-13 points, and more than 13 points, with associated 5-year survivals of 88%, 79%, 68%, and 49%, respectively. The model showed adequate discrimination and calibration, with a C-statistic of 0.69 and a calibration score of 0.99 (predicted 5-year survival of 0.78 compared with an observed 5-year survival of 0.77) and a Brier score of 0.15. Internal validation demonstrated an optimism corrected C-statistic of 0.69 and a calibration slope of 1.0. CONCLUSIONS: Elective EVAR in elderly patients chosen to undergo repair is associated with acceptable perioperative mortality. Our risk score can be used to define optimal patients for expanded screening into all but the highest risk group based on expected postoperative 5-year survival to justify removing this Medicare coverage restriction. PMID- 30301693 TI - Three-dimensional image fusion is associated with lower radiation exposure and shorter time to carotid cannulation during carotid artery stenting. AB - OBJECTIVE: Three-dimensional (3D) image fusion is associated with lower radiation exposure, contrast agent dose, and operative time during endovascular abdominal aortic aneurysm repair. Therefore, we evaluated the impact of this technology on carotid artery stenting (CAS). METHODS: We identified consecutive CAS procedures from 2009 to 2017 and compared those performed with and without 3D image fusion. For image fusion, we created a 3D reconstruction of the aortic arch anatomy based on preoperative computed tomography or magnetic resonance angiography that we merged with two-dimensional fluoroscopy, allowing 3D image overlay. We compared radiation exposure, fluoroscopy time, contrast agent dose, time to common carotid artery (CCA) cannulation, time from CCA cannulation to completion angiography, and total procedure time in procedures with and without image fusion. We also assessed rates of 30-day stroke/death, in-hospital and 30-day stroke, and acute kidney injury. We used multivariable linear regression to adjust for patient and procedural characteristics and used these models to compute the marginal effects of image fusion compared with no image fusion. RESULTS: There were 46 patients who underwent CAS with a 3D image fusion system and 70 patients without. Patients undergoing CAS with image fusion experienced 31% lower radiation exposure compared with the control group (207 +/- 23 mGy vs 300 +/- 26 mGy, respectively; P < .01), shorter fluoroscopy time (21 +/- 6 minutes vs 24 +/- 8 minutes; P = .02), shorter time to carotid cannulation (21 +/- 9 minutes vs 31 +/- 8 minutes; P < .001), and shorter total procedure time (47 +/- 13 minutes vs 54 +/- 18 minutes; P = .03). There was no difference in contrast material volume, time from CCA cannulation to completion angiography, or total in-room time. After multivariable adjustment, 3D image fusion remained associated with lower radiation dose, shorter fluoroscopy time, and shorter time to carotid cannulation (all P < .05). The rate of 30-day stroke/death was 2.7% (three strokes and no deaths at 30 days), and the rate of acute kidney injury was 1.8%. CONCLUSIONS: CAS with 3D image fusion was associated with lower radiation exposure and shorter time to CCA cannulation. These results represent the potential technical advantage gained with image fusion and add to the growing body of evidence demonstrating its impact on radiation exposure and operative times during complex endovascular procedures. PMID- 30301694 TI - Identifying the Optimal Candidate for Salvage Lymph Node Dissection for Nodal Recurrence of Prostate Cancer: Results from a Large, Multi-institutional Analysis. AB - BACKGROUND: Salvage lymph node dissection (SLND) represents a possible treatment option for prostate cancer patients affected by nodal recurrence after local treatment. However, SLND may be associated with intra- and postoperative complications, and the oncological benefit may be limited to specific groups of patients. OBJECTIVE: To identify the optimal candidates for SLND based on preoperative characteristics. DESIGN, SETTING, AND PARTICIPANTS: The study included 654 patients who experienced prostate-specific antigen (PSA) rise and nodal recurrence after radical prostatectomy (RP) and underwent SLND at nine tertiary referral centers. Lymph node recurrence was documented by positron emission tomography/computed tomography (PET/CT) scan using either 11C-choline or 68Ga-labeled prostate-specific membrane antigen ligand. INTERVENTION: SLND. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The study outcome was early clinical recurrence (eCR) developed within 1 yr after SLND. Multivariable Cox regression analysis was used to develop a predictive model. Multivariable-derived coefficients were used to develop a novel risk calculator. Decision-curve analysis was used to evaluate the net benefit of the predictive model. RESULTS AND LIMITATIONS: Median follow-up was 30 (interquartile range, 16-50) mo among patients without clinical recurrence (CR), and 334 patients developed CR after SLND. In particular, eCR at 1 yr after SLND was observed in 150 patients, with a Kaplan-Meier probability of eCR equal to 25%. The development of eCR was significantly associated with an increased risk of cancer-specific mortality at 3 yr, being 20% versus 1.4% in patients with and without eCR, respectively (p<0.0001). At multivariable analysis, Gleason grade group 5 (hazard ratio [HR]: 2.04; p<0.0001), time from RP to PSA rising (HR: 0.99; p=0.025), hormonal therapy administration at PSA rising after RP (HR: 1.47; p=0.0005), retroperitoneal uptake at PET/CT scan (HR: 1.24; p=0.038), three or more positive spots at PET/CT scan (HR: 1.26; p=0.019), and PSA level at SLND (HR: 1.05; p<0.0001) were significant predictors of CR after SLND. The coefficients of the predictive model were used to develop a risk calculator for eCR at 1 yr after SLND. The discrimination of the model (Harrel'sC index) was 0.75. At decision-curve analysis, the net benefit of the model was higher than the "treat-all" option at all the threshold probabilities. CONCLUSIONS: We reported the largest available series of patients treated with SLND. Roughly 25% of men developed eCR after surgery. We developed the first risk stratification tool to identify the optimal candidate to SLND based on routinely available preoperative characteristics. This tool can be useful to avoid use of SLND in men more likely to progress despite any imaging-guided approach. PATIENT SUMMARY: The risk of early recurrence after salvage lymph node dissection (SLND) was approximately 25%. In this study, we developed a novel tool to predict the risk of early failure after SLND. This tool will be useful to identify patients who would benefit the most from SLND from other patients who should be spared from surgery. PMID- 30301695 TI - Prognostic Implication of the United States Food and Drug Administration-defined BCG-unresponsive Disease. AB - The category "BCG-unresponsive disease", formulated by experts at the request of the United States Food and Drug Administration, denotes a group of patients with recurrent non-muscle-invasive bladder cancer for whom continued BCG treatment is unlikely to provide benefit. Although quickly adopted for trial design, many of the nuances within the definition lack validation. In this study, we evaluated the prognostic value of BCG unresponsive designation (i.e. recurrence after induction plus at least 1 maintenance course of BCG) by comparing the oncologic outcomes of these patients with those recurring after induction BCG alone. We confirm that appropriately defined, BCG-unresponsive patients are more likely to require salvage radical cystectomy (54.5% vs 17.9%, p=0.002). Moreover, those opting for second-line bladder-sparing therapies are less likely to remain free of tumor recurrence (23% vs 69.2%, p=0.003). On multivariate analysis, BCG unresponsive disease independently predicts inferior high-grade recurrence-free survival (hazard ratio [HR]: 6.25, 95% confidence interval [CI]: 2.27-16.67; p<0.001) and cystectomy-free survival (HR: 3.85, 95% CI: 1.49-10.0; p=0.006). Our data confirm the prognostic implication of the BCG unresponsive definition i.e. recurrence of high grade disease after induction and one course of maintenance BCG, and support its use in counseling and risk stratification of patients with tumor recurrence after BCG. Patient summary: Patients who have BCG-unresponsive disease, that is, high-grade non-muscle-invasive bladder cancer recurring after BCG induction and maintenance, have a low likelihood to respond to further BCG treatment and should consider radical cystectomy or clinical trial enrollment. PMID- 30301696 TI - A Prospective Study of the Association between Physical Activity and Risk of Prostate Cancer Defined by Clinical Features and TMPRSS2:ERG. AB - BACKGROUND: Growing evidence shows that clinical and molecular subtypes of prostate cancer (PCa) have specific risk factors. Observational studies suggest that physical activity may lower the risk of aggressive PCa. To our knowledge, the association between physical activity and PCa defined by TMPRSS2:ERG has not been evaluated. OBJECTIVE: To prospectively examine the association between physical activity and risk of PCa defined by clinical features and TMPRSS2:ERG. DESIGN, SETTING, AND PARTICIPANTS: We studied 49160 men aged 40-75 yr in the Health Professionals Follow-up Study from 1986 to 2012. Data was collected at baseline and every 2 yr with >90% follow-up. Total and vigorous physical activity were measured in metabolic equivalent of task (MET)-h/wk. OUTCOME MEASURES AND STATISTICAL ANALYSIS: Advanced PCa was defined as stage T3b, T4, N1, or M1 at diagnosis and lethal PCa as distant metastases or death due to disease over follow-up. Presence of TMPRSS2:ERG was estimated by immunohistochemistry of ERG protein expression. Cox proportional hazards models were used to obtain multivariable hazard ratios (HRs) and 95% confidence intervals (CIs) for incidence of subtype-specific PCa. RESULTS AND LIMITATIONS: During 26 yr of follow-up, 6411 developed PCa overall and 888 developed lethal disease. There were no significant associations between total physical activity and risk of PCa in the overall cohort. In multivariable-adjusted models, men in the highest quintile of vigorous activity had a significant 30% lower risk of advanced PCa (HR: 0.70, 95% CI: 0.53-0.92) and 25% lower risk of lethal PCa (HR: 0.75, 95% CI: 0.59-0.94) than men in the lowest quintile of vigorous activity. The association was independent of screening history. Vigorous activity was not associated with total PCa in the overall cohort but was inversely associated among highly screened men (top vs bottom quintile, HR: 0.83, 95% CI: 0.70-0.97). Of all cases, 945 were assayed for ERG (48% ERG-positive). Men with higher vigorous activity had a lower risk of ERG-positive PCa (top vs bottom quintile, HR: 0.71, 95% CI: 0.52-0.97). There was no significant association with the risk of ERG-negative disease (p heterogeneity=0.09). CONCLUSIONS: Our study confirms that vigorous physical activity is associated with lower risk of advanced and lethal PCa and provides novel evidence for a lower risk of TMPRSS2:ERG-positive disease. PATIENT SUMMARY: The identification of modifiable lifestyle factors for prevention of clinically important prostate cancer (PCa) is needed. In this report, we compared risk of PCa in men with different levels of physical activity. Men with higher vigorous activity had a lower risk of developing advanced and lethal PCa and PCa with the common TMPRSS2:ERG gene fusion.

Port-site Metastases After Robot-assisted Radical Cystectomy: Is There a Publication Bias? Eur Urol 2018;73:641-2. PMID- 30301698 TI - Focal therapy in localised prostate cancer: Real-world urological perspective explored in a cross-sectional European survey. AB - INTRODUCTION: The urological community's opinion over focal therapy (FT) for prostate cancer (PCa) has never been assessed. Our aim was to investigate the current opinion on FT in the European urological community. METHODS: A 25-item questionnaire was devised according to the Cherries checklist and distributed through SurveyMonkey using a web link from November 2016 to October 2017. After a pilot validation (n = 40 urologists), the survey was sent through EAU and 9 other national European urological societies mailing list. Twitter was also used. RESULTS: We received 484 replies from 51 countries. Almost half (44.8%, n = 217) stated FT would represent a step forward, and 52.0% (n = 252) would suggest FT to a patient. Almost three-quarters (70.8%, n = 343) agreed FT will become a standard option after improvements in patient selection (n = 66) or when its effectiveness will be proven (n = 78), or both (n = 199). Most frequently used definition of FT was treatment of all significant (life-threatening) cancer foci whilst leaving untreated the rest of the gland (39.3%, n = 190). FT use was considered as an alternative to whole-gland treatments by 29.7% (n = 144), and to AS by 25.0% (n = 121). On multivariate analysis, FT availability and publications were associated with a positive opinion on FT. Conversely, attending International congresses, treating high PCa volumes and high percentages of high risk PCa was associated with a negative opinion. CONCLUSIONS: FT is considered as an attractive option for PCa treatment by the European urological community sampled by our survey. FT availability positively influences these thoughts. The present survey suggests whilst some early adopters already embraced FT, the relative majority of the urological community is prone to embrace FT in the near future, once current areas of debate are solved. PMID- 30301699 TI - Predictive role of changes in the tumor burden and International Metastatic Renal Cell Carcinoma Database Consortium class during active surveillance for metastatic renal cell carcinoma. AB - BACKGROUND: Despite important results achieved for metastatic renal cell carcinoma, some patients could benefit from local treatments or an initial active surveillance (AS) period for recurrent disease. We aim to analyze: changes in the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk class, the number of metastases and the disease burden from the start of AS to the beginning of systemic therapy; and if these changes influenced patient outcomes. PATIENTS AND METHODS: Patients who started AS at our institution from January 2007 to April 2016 were included. The Kaplan-Meier method was used to estimate total overall survival (tOS) and progression-free survival. Changes in IMDC class, number of metastatic sites, and tumor burden (TB) were evaluated and related to patient survival. Among the patients who started active treatment, progression-free survival and post surveillance OS (psOS) were evaluated. RESULTS: 52 patients were included in the analysis. Median time on AS and tOS were 18.3 and 80.1 months respectively. Baseline factors were not related to the time on AS apart from the IMDC classification (HR = 2.15; 95% CI: 1.19-3.87; P = 0.011). The increase in the number of metastatic sites during AS was correlated with poor tOS (HR = 2.86; 95% CI: 1.29-6.34; P = 0.010). The increase of the TB was a negative prognosis factor for tOS (HR = 1.16; 95% CI: 1.02-1.31; P = 0.024) and psOS (HR = 1.21; 95% CI: 1.07-1.40; P = 0.004). Both IMDC class and change in the TB at the start of therapy were related to psOS. The retrospective nature and the lack of an external review of the imaging are its main limitations. CONCLUSIONS: During AS, patients rarely experience a deterioration of their IMDC prognostic class, and the change in the TB, more than the increase in the number of metastatic sites, may help physicians to make decisions about the early termination of AS and the start of systemic therapy.

While radical inguinal lymphadenectomy has been the cornerstone of regional lymph node management for many years, it is still associated with significant morbidity and psychological distress. Recent developments in penile squamous cell carcinoma management have been met with some controversy in the urologic oncology community. Herein, we review the current controversies and developments on the role of inguinal lymphadenectomy for penile cancer.

AB - BACKGROUND: The recent introduction of new arboviruses in the Americas, as Zika virus (ZIKV) and Chikungunya virus (CHIKV), increased the risk of outbreaks and arboviral co-infections. Herein, we report twelve cases of co-infection of ZIKV and different DENV serotypes in a city located in the northwest region of Sao Paulo State, Brazil, which is hyper-endemic to Dengue. METHODS: Between January and November 2016, 1254 suspected cases of arboviral infection were available by our surveillance program in Sao Jose do Rio Preto. All suspected patients were examined and, when they were arboviral disease-suspectd, had sera separated and viral RNA analyzed by PCR/qPCR assays to determine the diagnosis of DENV 1-4, ZIKV, or CHIKV in the same samples. After the molecular results, twelve patients with ZIKV-DENV coinfection were identified and their clinical and laboratory characteristics were described. RESULTS: The mean between symptoms onset and collected sample of 3 days. DENV-1 was identified in seven co-infected patients and DEN2 in other five. Two patients presented alarm signs of Dengue and no one was hospitalized. CONCLUSIONS: The constant presence of co-circulating arboviruses increases the chance of co-infection and demonstrates the importance of the differential diagnosis, especially during periods of arboviral outbreaks. The impact of this co-infection is known individual and collectively. PMID- 30301702 TI - BJORL: moving forward, always.

AB - INTRODUCTION: 5-Alpha reductase inhibitors (5-ARIs) are widely used in the treatment of benign prostatic hyperplasia (BPH) and androgenic alopecia (AGA). AIM: To examine all available data on the effects of 5-ARIs on sexual functioning in AGA treatment and to assess whether 5-ARIs increase the risk of sexual dysfunction. METHODS: A literature review of publications at PubMed related to the subject was used. MAIN OUTCOME MEASURE: We assessed erectile dysfunction, ejaculation impairment, and decreased libido. RESULTS: 5-ARIs may cause side effects such as erectile dysfunction, ejaculation problems, and decreased libido in patients. Their long-term impact and precise mechanism have not been clarified. Data from studies on 5-ARIs are important for drug selection and patient counseling. More training and awareness is needed for clinicians and patients to recover many patients from sexual adverse effects. CONCLUSION: 5-ARIs used in the treatment of AGA have well-defined side effects, which can negatively affect sexual life. It is unknown and unpredictable which men using these drugs may be subject to these side effects and when these effects may appear. Studies have been insufficient to provide a clear answer to this question. Coskuner ER, Ozkan B, Culha MG. Sexual Problems of Men With Androgenic Alopecia Treated With 5 Alpha Reductase Inhibitors.

AB - INTRODUCTION: Care-seeking for sexual dysfunction is limited by embarrassment, efficacy/safety concerns, and cost. Nutritional supplements (NSs) are low-cost but unproven. AIM: To provide hypotheses on whether effective NS combinations for sexual dysfunction can be created following known pharmacology principles and tested with sufficient rigor in Internet-based "exo-clinical" trials (XCTs). METHODS: PubMed and Google searches were conducted to review the feasibility of XCTs of NS combinations for sexual dysfunction. Findings were synthesized into recommendations for XCTs to treat the most common sexual problems. MAIN OUTCOME MEASURE: The hierarchy of references used for making recommendations was controlled clinical trials over uncontrolled trials. The frequency of sexual dysfunction was determined in population-representative national surveys. RESULTS: XCTs of cognitive behavioral therapy show conclusive efficacy for anxiety and depression. 5 small XCTs showed efficacy for female sexual dysfunction and erectile dysfunction (ED), and 2 XCTs of NS for other medical problems substantiated feasibility. To test the feasibility of XCTs for the most common forms of sexual dysfunction-ED, hypoactive sexual desire disorder (HSDD), and sexual performance anxiety-protocol outlines were generated for frugal XCTs; the total estimated subject time burden is <=1 hour. CONCLUSION: An XCT is a cost effective method of evaluating new treatments, including sexual dysfunction and common mental disorders, if compliance is maintained by regular outreach while minimizing the time burden on subjects and handling consent and privacy issues appropriately. NS combinations might expand the opportunities for relief of sexual dysfunction if formulated with pharmacologically active doses of NS with already supported efficacy and safety. The feasibility of XCTs of NS combinations for sexual dysfunction might be tested most productively in men with ED, in women with HSDD, and in men and women with sexual performance anxiety. Pyke RE.

PMID- 30301705 TI - The Effect of Pelvic Floor Muscle Exercise on Female Sexual Function During Pregnancy and Postpartum: A Systematic Review. AB - INTRODUCTION: Pelvic floor muscle exercise (PFME) is recommended as a first-line treatment for urinary incontinence. However, a review of the literature suggests the effect of PFME on sexual function (SF), particularly during pregnancy and the postpartum period, is understudied. AIM: To assess the effect of PFME on SF during pregnancy and the postpartum period. METHODS: The following databases were searched: CINAHL (EBSCOhost), Health Collection (Informit), PubMed (National Center for Biotechnology Information), Embase (Ovid), MEDLINE, Cochrane, Health Source, Scopus, Wiley, Health & Medical Complete (ProQuest), Joanna Briggs Institute, and Google Scholar. Results from published randomized controlled trials (RCTs) and non-RCTs from 2004 to January 2018 on pregnant and postnatal women were included. PEDro and Critical Appraisal Skills Programme scores were used to assess the quality of studies. Data were analysed using a qualitative approach. MAIN OUTCOME MEASURE: The primary outcome was the impact of antenatal or postnatal PFME on at least 1 SF variable, including desire, arousal, orgasm, pain, lubrication, and satisfaction. The secondary outcome was the impact of PFME on PFM strength. RESULTS: We identified 10 studies with a total of 3607 participants. These included 4 RCTs, 1 quasi-experimental study, 3 interventional cohort studies, and 2 long-term follow up cohort studies. No studies examined the effect of PFME on SF during pregnancy. 7 studies reported that PFME alone improved sexual desire, arousal, orgasm, and satisfaction in the postpartum period. CONCLUSION: The current data needs to be interpreted in the context of the studies' risk of bias, small sample sizes, and varying outcome assessment tools. The majority of the included studies reported that postnatal PFME was effective in improving SF. However, there is a lack of studies describing the effect of PFME on SF during pregnancy, and only minimal data are available on the postpartum period. More RCTs are needed in this area.

PMID- 30301706 TI - Genital Sensations in Persistent Genital Arousal Disorder: A Case for an Overarching Nosology of Genitopelvic Dysesthesias? AB - INTRODUCTION: Persistent genital arousal disorder (PGAD) is a highly distressing and poorly understood condition characterized by unwanted sensations of genital arousal in the absence of subjective sexual desire. Research has shown that some individuals with PGAD also report orgasm, urinary, and pain symptoms, with 1 recent study specifically comparing a "painful persistent genital arousal symptom" group to a "non-painful persistent genital arousal symptom" group on various indicators given the highly frequent report of comorbid genitopelvic pain in their sample. AIM: To review literature on PGAD focusing on the presence of pain symptoms. METHODS: A literature review through May 2018 was undertaken to identify articles that discuss pain characteristics in individuals with persistent sexual arousal syndrome, persistent genital arousal disorder, symptoms of persistent genital arousal, and restless genital syndrome. MAIN OUTCOME MEASURE: A review of pain/discomfort associated with persistent genital arousal, and the proposal of a new theoretical framework of genitopelvic dysesthesias. RESULTS: PGAD is a distressing condition that is associated with a significant, negative impacts on psychosocial and daily functioning. Although it is clear that unwanted and persistent genital arousal is the hallmark symptom of PGAD, symptoms of pain and discomfort are also frequently reported. Based on the results of this review, a model of genitopelvic dysesthesias is proposed, with subcategories of unpleasant sensations that are based on patients' primary complaint: arousal, arousal and pain, or pain (and other sensations). CONCLUSION: The proposed model can provide an important framework for conceptualizing conditions characterized by unpleasant genitopelvic sensations. A model such as this one can benefit highly misunderstood conditions that are questioned in terms of their legitimacy and severity-such as PGAD-by conceptualizing them as sensory disorders, which in turn can reduce stigma, unify research efforts, and potentially improve access to care.

AB - INTRODUCTION: The serendipitous discovery of sildenafil (Viagra [sildenafil citrate]) as a treatment for erectile dysfunction (ED) is one of the most fascinating drug development stories of our time. When sildenafil was approved by the U.S. Food and Drug Administration in 1998, it revolutionized the treatment protocol for men with ED, once considered a psychological issue or an inevitable part of aging. AIM: To review the discovery of sildenafil and its role in changing the field of sexual medicine in the context of the epidemiology and history of treatment for ED. METHODS: For this narrative review, a literature search was conducted to identify essential articles and was supplemented by author observations from a historical perspective. MAIN OUTCOME MEASURE: A broad overview of ED and its past, current, and future treatments. RESULTS: ED is a prevalent condition for which medical treatment had been limited to genitally localized interventions, including surgery, vacuum pumps, injectable therapies, and intraurethral suppositories. The discovery of sildenafil provided a safe, oral pharmacotherapy for the treatment of ED, sparking greater understanding of the science behind ED and its role in men's overall health. CONCLUSION: The approval of sildenafil initiated a global conversation about ED that had profound implications for patients, methods of clinical practice, and academic sexual medicine. These changes will catalyze continued advances in ED treatment. Goldstein I, Burnett AL, Rosen RC, et al. The serendipitous story of sildenafil: an unexpected oral therapy for erectile dysfunction.

AB - INTRODUCTION: Peyronie's disease (PD) is associated with penile length loss due to atrophy that occurs as a result of fibrous inelastic scarring. Studies have shown diminished penile length and girth, as well as the inability to participate in sexual activity, can lead to decreased quality of life, emotional challenges, and sexual dissatisfaction in a large percentage of men. AIM: To provide a summary of the new developments in the surgical techniques available for the PD patient, with a focus on procedures that provide penile size restoration. METHODS: A MEDLINE PubMed search was used to identify articles related to surgical treatments for PD, including plication procedures, penile prosthesis placement, and techniques for size restoration. MAIN OUTCOME MEASURE: Types of surgical treatments for PD and their outcomes regarding penile length and patient satisfaction. RESULTS: The Nesbit procedure, among other plication procedures, and penile prosthesis placement with modeling or plication are likely to decrease penile length. Although plaque incision with grafting offers restoration of penile length, it carries a risk of postoperative erectile dysfunction (ED). For men with concomitant ED and severe curvature not amenable to prosthesis with modeling or plication, options include grafting, circumferential tunical incisions, subcoronal prosthesis placement, and the sliding technique with its modifications, allowing for management of both PD and ED while restoring penile length. Adjunct procedures, such as ventral phalloplasty and suspensory ligament release, have also been shown to restore length in PD patients. Novel therapies continue to evolve with the goal of preserving length while treating curvature. CONCLUSION: There are numerous surgical options for correcting penile curvature in PD patients, with or without concomitant ED treatment. When determining the optimal procedure, it is important to consider possible preservation of penile length and to discuss possible complications to increase patient satisfaction and improve quality of life.

PMID- 30301709 TI - Toll-like receptor 2 and 4 polymorphisms associated with Helicobacter pylori susceptibility and gastric cancer. AB - BACKGROUND/AIMS: Genetic polymorphisms in Toll-like receptors (TLRs) are important influence on gastric lesion development and Helicobacter pylori susceptibility. MATERIALS AND METHODS: TLR2 rs3804099 and rs3804100 and TLR4 rs10759932 were determined in a total of 400 patients. The association among genotypes and the risk of gastric lesion development and H. pylori susceptibility were evaluated by the odds ratios (ORs) and 95% confidence intervals (95% CIs) from logistic regression analyses. RESULTS: TLR4 rs10759932, C/C homozygous genotype was associated with an increased risk of premalignant/malignant (OR=2.48, 95% CI=1.96-4.62, p=0.015). The recessive model of TLR4 rs10759932 showed a decreased risk of H. pylori susceptibility (adjusted OR=0.52, 95% CI=0.38-0.82, p=0.046). Meanwhile, the recessive model was associated with an increased risk of non-malignant (OR=3.46, 95% CI=2.25-5.67, p=0.001). In subjects with H. pylori infection, the recessive model was associated with an increased risk of non-malignant (OR=2.28, 95% CI=1.24-3.57, p=0.001) and premalignant/malignant (OR=1.83, 95% CI=1.16-2.84, p=0.027). CONCLUSION: TLR4 rs10759932, but not TLR2 rs3804099 and rs3804100, was associated with risk of premalignant and/or malignant and H. pylori susceptibility. H. pylori infection seems to contribute to chronic gastritis, and premalignant/malignant supported the development of the premalignant/malignant lesions involved in H. pylori infection that is critical to gastric cancer in Thai patients. PMID- 30301710 TI - Results of positive proximal margin after resection for hilar cholangiocarcinoma: An analysis of 42 cases. AB - BACKGROUND/AIMS: Hilar cholangiocarcinoma (HC) is a tumor that invades the confluence of the left and right hepatic bile ducts. Surgery is the definitive treatment but is also technically demanding. Here, we report our experience on 42 patients who underwent surgical resection for HC. The aim of the present study was to evaluate the margin status of resected specimens on frozen sections and the impact of R1 resection margin on survival. MATERIALS AND METHODS: A total of 42 patients with HC who underwent surgical resection in our clinic between January 2008 and January 2017 were included in the study. Patients' charts were evaluated retrospectively. RESULTS: The 1-, 2-, and 4-year overall survival rates of the 42 patients were 76.2%, 40%, and 10.7%, respectively. The median survival rates of the patients with negative and positive proximal surgical margins were 22 (11.93-32.06) and 17 (14.43-19.56) months, respectively. There was no statistically significant difference between these two groups. CONCLUSION: In HC, surgery achieving negative proximal surgical margin is often very difficult. Our results demonstrate that frozen sections are reliable for the assessment of the invasion status of the proximal and distal ductal surgical margins. Although complete resection is potentially curative, survival of the patients with HC is still poor. If there is no distant metastasis at the time of diagnosis, then extirpating surgery should be encouraged as survival of the patients with positive and negative margins is not significantly different. PMID- 30301711 TI - Incidence and epidemiological features of acute pancreatitis among adult inhabitants in Qatar. AB - BACKGROUND/AIMS: Acute pancreatitis (AP) is one of the most common gastrointestinal causes of hospital admission in Qatar. The aim of the present study was to investigate the epidemiological features and demographic characteristics of patients with AP and to estimate the annual incidence rates of this disease among adult inhabitants in Qatar. MATERIALS AND METHODS: This retrospective study was conducted using the data collected by reviewing records of patients with AP admitted to the medical and surgical wards of Hamad GeneralHospital and Alkhor Hospital, Qatar from January 2007 to December 2012. Diagnosis of AP was based on abdominal pain suggestive of AP, serum lipase and/or amylase at least three times the upper limit of normal, and/or characteristic findings of AP on abdominal ultrasound or computed tomography. RESULTS: A total of 382 AP events were reported in 334 patients. There were 250 (75%) males and 84 (25%) females. The mean age (+/-SD) of the patients was 56.8+/-18.7 years. Gallstone disease (40.6%) was the highest cause of AP, followed by alcohol consumption (28.5%) and idiopathic AP (20.7%). The mean annual incidence rate of AP was 5 per 100,000 adult inhabitants in Qatar from January 2007 to December 2012. The incidence rate among men was higher than that among women. Mortality rate was low (0.3%), and there were complications in 112 (29.3%) patients. CONCLUSION: The annual incidence rate of AP is relatively low in Qatar and tends to behave similar to many European countries in etiology, which can be explained by population structure. Gallstone and alcohol consumption are the main causes, and idiopathic AP is responsible for more cases than expected. PMID- 30301712 TI - [Online information system for -phytotherapy in animals]. AB - INTRODUCTION: Phytotherapy becomes increasingly popular in veterinary medicine. To fully exploit the therapeutic potential of medicinal plants and ensure their safe use, knowledge about the effective plant parts and preparations is required. Improper use and overdosage of medicinal plants can be toxic. With www.phytoarznei.ch, we provide an online decision support aid that allows for the retrieval of currently available information on medicinal plants and their use in domestic animals. This decision support system is based on the available literature in the field, which after critical evaluation has been incorporated into a structured database. For each medicinal plant or drug, we have listed therapeutic indications, different application types, organoleptic properties, plant ingredients, pharmacological effects, dosages, duration of treatment, toxicity, legal frame for use in livestock and relevance for doping. A user friendly access to all data is achieved by means of two search programs, either by entering the plant name or name of the drug in a search field or by selecting the desired animal species and therapeutic application from respective drop-down lists. This database on medicinal plant applications in animals is linked to the poisonous plant database of the University of Zurich and, for marketed preparations, to the Swiss compendium of veterinary medicinal products as well as to an index of related veterinary products.

AB - INTRODUCTION: The aim of the Vaccinovigilance system is the identification of adverse reactions and rare events after the use of immunological veterinary medicinal products. In the year 2017, 128 reports of adverse reactions following the application of various authorized vaccines were received and evaluated. The notifications were submitted primarily by marketing authorization holders (96) or veterinarians (27) and private persons (5). As in previous years, dogs were involved in most of the adverse effects (55%), followed by cattle (18%) and swine (10%). Unlike the previous years, significantly fewer reports were submitted on cats (8%). The correlation between reaction and vaccination was considered probable in 43% of the - cases.

AB - INTRODUCTION: A significant Antibiotic-Monitoring-System is essential to analyse the use of antibiotics and to a better understanding of trends in resistance development. In human and veterinary medicine, for example, a system based on defined daily and treatment doses (Defined Daily Dose: DDD and Defined Course Dose: DCD) is applied. These definitions can be used to estimate the number of treatment days and treatments with antimicrobial agents in a population. For veterinary medicine, the European Medicines Agency (EMA) has published the European values DDDvet and DCDvet in the farm animal sector. The aim of this study was to define Swiss daily and treatment doses (DDDch and DCDch) for the treatment of pigs and to compare them with the EMA values in order to investigate the differences between individually collected national doses and average international doses. For the comparison, the quotient of Swiss and European values was calculated and the influence of the application form of an active substance and the number of active substances contained in a preparation was investigated. One hundred and three veterinary preparations with 138 active substances were assigned a DDDch and DCDch value. A comparison with EMA values was possible for 118 active substances. The comparison showed median values of 0.91 for the daily doses and 0.90 for the treatment doses, so that the daily and treatment doses in Switzerland are lower than the corresponding EMA doses. Both the form of application (injection solutions: 1.00; premixes: 0.76; P=0.02) and the number of active substances in the preparation (one active substance: 1.00; two active substances: 0.76; three active substances: 0.43; each P.

PMID- 30301719 TI - Inflammatory signals directly instruct PU.1 in HSCs via TNF. AB - The molecular mechanisms governing the transition from hematopoietic stem cells (HSCs) to lineage-committed progenitors remain poorly understood. Transcription factors (TFs) are powerful cell intrinsic regulators of differentiation and lineage commitment, while cytokine signaling has been shown to instruct the fate of progenitor cells. However, the direct regulation of differentiation-inducing hematopoietic TFs by cell extrinsic signals remains surprisingly difficult to establish. PU.1 is a master regulator of hematopoiesis and promotes myeloid differentiation. Here we report that TNF can directly and rapidly up-regulate PU.1 protein in HSCs in vitro and in vivo. We demonstrate that in vivo, niche derived TNF is the principal PU.1 inducing signal in HSCs and is both sufficient and required to relay signals from inflammatory challenges to HSCs. PMID- 30301720 TI - Implementation of a pharmacogenomics education program for pharmacists. AB - PURPOSE: The development, implementation, and evaluation of a pharmacogenomics education program for pharmacists in a large, integrated multicampus health system are described. SUMMARY: Pharmacogenomics has been described as tailoring medications to each patient's unique genetic sequence with the goals of minimizing harmful effects and optimizing therapeutic effects. Pharmacists are uniquely trained to lead the implementation of pharmacogenomics in clinical care. After assessment of pharmacists' comfort with pharmacogenomics, different approaches were explored to develop, pilot test, and disseminate pharmacogenomics education across a multicampus academic medical center. Limited success with large-audience, single-lecture didactic education led to development and delivery of targeted, competency-based online modules using the institution's academic virtual learning environment and course management system. Implementation steps included (1) collaboration with the Mayo Clinic Center for Individualized Medicine to create an interprofessional development team and project charter, (2) galvanizing pharmacy leadership support across multiple campuses, (3) development of competency-based interactive modules, and (4) assessment of the quality of and learner satisfaction with the modules. Significant improvements in competency scores were observed with each module and across the multiple campuses. Satisfaction with the education program was assessed at the end of a 4-module series. CONCLUSION: A pharmacogenomics educational program targeting pharmacists was developed through interprofessional collaboration and provided a novel opportunity to construct an educational infrastructure to support enterprise health-system campuses with limited educational resources.

AB - PURPOSE: Safe transition of patients with pulmonary arterial hypertension (PAH) from parenteral treprostinil to oral selexipag therapy in both inpatient and outpatient settings is described. SUMMARY: There is a paucity of published data on how to safely transition patients to oral therapy in the event of complications and problems during parenteral administration of prostacyclins, which can include bloodstream infections, injection-site pain (with use of subcutaneous treprostinil), infusion pump malfunction, and dosing errors due to incorrect dose preparation. This case series describes the transition of 4 patients with World Health Organization (WHO) group I PAH (WHO functional classes II-IV) from i.v. (n = 3) and subcutaneous (n = 1) treprostinil infusion therapy to oral selexipag use. The transition process was completed through the use of 2 cross-titration methods (rapid and slow). A rapid approach was used in 2 cases involving inpatients, with parenteral-to-oral transition completed over 8-13 days; a slow transition method was used in 2 cases, in which outpatients completed the transition over 19-25 weeks. Adverse events during the transitions were headache, nausea, vomiting, diarrhea, and jaw pain. CONCLUSION: Four patients with WHO group I PAH who were not candidates for continued parenteral treprostinil therapy were safely transitioned to oral selexipag in both inpatient and outpatient settings.

AB - Fat embolism syndrome (FES) is a rare multisystem, clinical syndrome occurring in 0.9%-2.2% of long-bone fractures. The severity of FES can vary from subclinical with mild respiratory changes and haematological aberrations to a fulminant state characterised by sudden onset of severe respiratory and neurological impairment. Here we present two patients with cerebral FES secondary to femur fracture. Both patients exhibited profound neurological impairment with varied outcomes. Our cases highlight the importance of a high clinical suspicion of FES in patients with long-bone fractures and neurological deterioration. We recommend early plate osteosynthesis to prevent additional emboli in patients with FES and situational placement of intracranial pressure monitoring. Finally, cerebral FES has low mortality even in a patient with tentorial herniation and fixed, dilated pupils. PMID- 30301726 TI - Visual deficit possibly caused by lutetium-177 PSMA treatment. AB - This report describes a case of a 54-year-old man who underwent lutetium-177-PSMA therapy in the setting of metastatic castration-resistant prostate cancer (mCRPC) in the University Medical Center Utrecht. Following administration of the second cycle, patient presented with a slowly impairing, bilateral visual loss. This clinical presentation was most likely the result of the high intracranial pressure due to impediment of cerebrospinal fluid circulation, possibly related to obstructive dural thickness, being either caused by dural and/or leptomeningeal metastases of advanced mCRPC or by local radiation effects following lutetium-177-PSMA therapy. Describing this case, we aim to add to the discussion on 177Lu-PSMA safety, in which prospective research will ultimately offer definite answers.

AB - A 14-year-old young adult took an overdose of 1.2 g of fluoxetine, a selective serotonin reuptake inhibitor (SSRI) that he had been prescribed for depression. He had a generalised tonic/clonic seizure at 6 hours postingestion.After the seizure, he developed signs consistent with serotonin syndrome: fine tremor, agitation, sweating and hyperreflexia. This was followed by severe muscle pain and rhabdomyolysis with peak creatine kinase (CK) of 33 941 at 74 hours. He was managed with intravenous fluids and analgesia and discharged after 4 days, having avoided renal injury. The use of SSRI's such as fluoxetine in teenagers has increased in recent years. While it is generally considered benign in overdose, this report illustrates the severe consequences of overdose at high quantities and discusses appropriate management in these cases. We note that in this case, there was a delayed onset of rhabdomyolysis with peak CK at 74 hours postingestion.

AB - A 53-year-old man with a 1-year history of chronic lymphocytic leukaemia (CLL) presented with a left bicep mass. Biopsy and staging workup revealed Richter's transformation (RT) Ann Arbor stage 1E diffuse large B-cell lymphoma in the bicep. The patient was treated with combination chemotherapy with cyclophosphamide, doxorubicin, Vincristine and prednisone followed by site radiation and did well thereafter. His CLL progressed and required treatment on two more occasions 11 and 18 years after his initial diagnosis with fludarabine, Cytoxan and Rituxan and then with bendamustine and rituximab. 23 years after initial presentation, he developed diffuse lymphadenopathy and B-symptoms. A biopsy of an enlarged cervical lymph node demonstrated only CLL for which he was started on ibrutinib. Treatment was shortly discontinued thereafter due to intolerance and worsening symptoms. A second biopsy was performed which revealed concurrent CLL and Hodgkin's lymphoma representing a second and histologically distinct RT. PMID- 30301729 TI - Severe pneumonitis refractory to steroids following anti-PD-1 immunotherapy. AB - Anti-programmed death 1 (PD-1) immune checkpoint inhibitors enhance the antitumour activity of the immune system and have produced durable tumour responses in several solid tumours including non-small cell lung cancer (NSCLC). However, PD-1 inhibitors can lead to immune-related adverse events , including pneumonitis, which is typically mild, but can be severe and potentially fatal. Pneumonitis often resolves with steroids, but some cases are steroid refractory, leading to a relapsing and remitting course in milder cases or the need for salvage therapies in more severe cases. Here, we present two patients with NSCLC who developed severe pneumonitis following therapy with nivolumab and pembrolizumab. While one patient improved with steroids and infliximab, the other patient failed to respond to steroids and subsequently died. These cases demonstrate the highly variable presentation and therapeutic responses seen in patients with pneumonitis following anti-PD-1 therapy and illustrate that severe cases can often present refractory to steroid therapy.

PMID- 30301731 TI - Ascites with hepatic extravasation of total parenteral nutrition (TPN) secondary to umbilical venous catheter (UVC) malposition in an extremely preterm baby. AB - The ease of access and advantages of a secure central line makes use of umbilical venous catheter (UVC) and umbilical artery catheters a part of the standard of care in the extremely premature babies in the neonatal intensive care unit. However, there are complications associated with their use. One of the uncommon complications reported is total parenteral nutrition (TPN) ascites secondary to vessel perforation or hepatic erosion by the tip of the catheter due to malposition of a UVC. We present here a case of such catheter perforation causing ascites and right hepatic collection of TPN in a 28-week-old infant. Abdominal paracentesis was therapeutic by relieving the distension as well as confirming the presence of parenteral nutrition in the peritoneal cavity. PMID- 30301732 TI - DRESS syndrome-associated acute necrotizing eosinophilic myocarditis with giant cells. AB - Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is an uncommon drug hypersensitivity reaction caused by a wide variety of agents. It has a characteristic latent period between 2 and 8 weeks from the onset of drug ingestion followed by a slow resolution with the potential for relapse. Despite being a potentially fatal disease, little is understood about its variable clinical presentation and why it can present long after removal of the offending drug. Visceral organ involvement typically occurs, but rarely results in clinically manifested cardiac injury. In its most aggressive form, acute necrotizing eosinophilic myocarditis (ANEM) can present with DRESS. We present an unusual case of DRESS syndrome due to lamotrigine with confirmed ANEM showing both eosinophils and rare giant cell infiltrates on endomyocardial biopsy. Although lamotrigine has been reported to cause DRESS, it has not been previously implicated as a cause of ANEM.

PMID- 30301734 TI - Oestrogen replacement improves bone mineral density in oligo-amenorrhoeic athletes: a randomised clinical trial. AB - OBJECTIVE: Normal-weight oligo-amenorrhoeic athletes (OAA) are at risk for low bone mineral density (BMD). Data are lacking regarding the impact of oestrogen administration on bone outcomes in OAA. Our objective was to determine the effects of transdermal versus oral oestrogen administration on bone in OAA engaged in weight-bearing activity. METHODS: 121 patients with OAA aged 14-25 years were randomised to receive: (1) a 17beta-estradiol transdermal patch continuously with cyclic oral micronised progesterone (PATCH), (2) a combined ethinyl estradiol and desogestrel pill (PILL) or (3) no oestrogen/progesterone (NONE). All participants received calcium and vitamin D supplementation. Areal BMD was assessed at the lumbar spine, femoral neck, total hip and total body less head using dual-energy X-ray absorptiometry at baseline, 6 and 12 months. Intention-to-treat (ITT) and completers analyses were performed. RESULTS: Randomised groups did not differ for age, body mass index or BMD Z-scores at baseline. For ITT analysis, spine and femoral neck BMD Z-scores significantly increased in the PATCH versus PILL (p=0.011 and p=0.021, respectively) and NONE (p=0.021 and p=0.033, respectively) groups, and hip BMD Z-scores significantly increased in the PATCH versus PILL group (p=0.018). Similar findings were noted in completers analysis. CONCLUSION: Transdermal estradiol over 12 months improves BMD in young OAA, particularly compared with an ethinyl estradiol-containing contraceptive pill/oral contraceptives.

AB - OBJECTIVE: To produce a best evidence synthesis of the clinical effects of topical glyceryl trinitrate (GTN) in the treatment of tendinopathies. DESIGN: A systematic review of published randomised controlled trials (RCTs) of the use of GTN in patients with tendinopathy. DATA SOURCES: MEDLINE, Embase, Scopus and CINAHL from database inception to January 2018. METHODS: We examined RCTs comparing the effects of topical GTN with either placebo or other treatments on tendinopathy. Overall quality of each eligible study was determined based on a combined assessment of internal validity, external validity and precision. The level of evidence for each assessed parameter was rated based on the system by van Tulder et al. RESULTS: A total of 10 eligible RCTs were identified including patients with tendinopathy of the rotator cuff (n=4), wrist extensors (n=3), Achilles (n=2) and patellar (n=1) tendons. For all tendinopathies, improvements in pain were significant when comparing GTN versus placebo in the short term (<8 weeks; poor evidence). Significant improvements in midterm outcomes for treatment with GTN versus placebo included the following: patient satisfaction (strong evidence); chances of being asymptomatic with activities of daily living (strong evidence); range of movement (moderate evidence); strength (moderate evidence); pain (at night and with activity; poor evidence) and local tenderness (poor evidence). Patients treated with topical GTN reported a higher incidence of headaches than those who received placebo (moderate evidence). CONCLUSIONS AND RELEVANCE: Treatment of tendinopathies with topical GTN for up to 6 months appears to be superior to placebo and may therefore be a useful adjunct to the treating healthcare professions. PMID- 30301736 TI - Glucocorticoid-Induced Leucine Zipper Promotes Neutrophil and T-Cell Polarization with Protective Effects in Acute Kidney Injury. AB - The glucocorticoid-induced leucine zipper (GILZ) mediates anti-inflammatory effects of glucocorticoids. Acute kidney injury (AKI) mobilizes immune/inflammatory mechanisms, causing tissue injury, but the impact of GILZ in AKI is not known. Neutrophils play context-specific proinflammatory [type 1 neutrophil (N1)] and anti-inflammatory [type 2 neutrophil (N2)] functional roles. Also, regulatory T lymphocytes (Tregs) and regulatory T-17 (Treg17) cells exert counterinflammatory effects, including the suppression of effector T lymphocytes [e.g., T-helper (Th) 17 cells]. Thus, utilizing cell preparations of mice kidneys subjected to AKI or sham operation, we determined the effects of GILZ on T cells and neutrophil subtypes in the context of its renoprotective effect; these studies used the transactivator of transcription (TAT)-GILZ or the TAT peptide. AKI increased N1 and Th-17 cells but reduced N2, Tregs, and Treg17 cells in association with increased interleukin (IL)-17+ but reduced IL-10+ cells accompanied with the disruption of mitochondrial membrane potential (psi m) and increased apoptosis/necrosis compared with sham kidneys. TAT-GILZ, compared with TAT, treatment reduced N1 and Th-17 cells but increased N2 and Tregs, without affecting Treg17 cells, in association with a reduction in IL-17+ cells but an increase in IL-10+ cells; TAT-GILZ caused less disruption of psi m and reduced cell death in AKI. Importantly, TAT-GILZ increased perfusion of the ischemic reperfused kidney but reduced tissue edema compared with TAT. Utilizing splenic T cells and bone marrow-derived neutrophils, we further showed marked reduction in the proliferation of Th cells in response to TAT-GILZ compared with response to TAT. Collectively, the results indicate that GILZ exerts renoprotection accompanied by the upregulation of the regulatory/suppressive arm of immunity in AKI, likely via regulating cross talk between T cells and neutrophils. PMID- 30301737 TI - Genotype-by-Environment-by-Environment Interactions in the Saccharomyces cerevisiae Transcriptomic Response to Alcohols and Anaerobiosis. AB - Next generation biofuels including longer-chain alcohols such as butanol are attractive as renewable, high-energy fuels. A barrier to microbial production of butanols is the increased toxicity compared to ethanol; however, the cellular targets and microbial defense mechanisms remain poorly understood, especially under anaerobic conditions used frequently in industry. Here we took a comparative approach to understand the response of Saccharomyces cerevisiae to 1 butanol, isobutanol, or ethanol, across three genetic backgrounds of varying tolerance in aerobic and anaerobic conditions. We find that strains have different growth properties and alcohol tolerances with and without oxygen availability, as well as unique and common responses to each of the three alcohols. Our results provide evidence for strain-by-alcohol-by-oxygen interactions that moderate how cells respond to alcohol stress. PMID- 30301738 TI - 10q23.31 microduplication encompassing PTEN decreases mTOR signalling activity and is associated with autosomal dominant primary microcephaly. AB - BACKGROUND: Hereditary primary microcephaly (MCPH) is mainly characterised by decreased occipitofrontal circumference and variable degree of intellectual disability. MCPH with a dominant pattern of inheritance is a rare condition, so far causally linked to pathogenic variants in the ALFY, DPP6, KIF11 and DYRK1A genes. OBJECTIVE: This study aimed at identifying the causative variant of the autosomal dominant form of MCPH in a Brazilian family with three affected members. METHODS: Following clinical evaluation of two sibs and their mother presenting with autosomal dominant MCPH, array comparative genome hybridisation was performed using genomic DNA from peripheral blood of the family members. Gene and protein expression studies were carried out in cultured skin fibroblasts. RESULTS: A 382 kb microduplication at 10q23.31 was detected, encompassing the entire PTEN, KLLN and ATAD1 genes. PTEN haploinsufficiency has been causally associated with macrocephaly and autism spectrum disorder and, therefore, was considered the most likely candidate gene to be involved in this autosomal dominant form of MCPH. In the patients' fibroblasts, PTEN mRNA and protein were found to be overexpressed, and the phosphorylation patterns of upstream and downstream components of the mammalian target of rapamycin (mTOR) signalling pathway were dysregulated. CONCLUSIONS: Taken together, our results demonstrate that the identified submicroscopic 10q23.31 duplication in a family with MCPH leads to markedly increased expression of PTEN and reduced activity of the mTOR signalling pathway. These results suggest that the most probable pathomechanism underlying the microcephaly phenotype in this family involves downregulation of the mTOR pathway through overexpression of PTEN. PMID- 30301740 TI - Genome Instability Is Promoted by the Chromatin-Binding Protein Spn1 in Saccharomyces cerevisiae. AB - Cells expend a large amount of energy to maintain their DNA sequence. DNA repair pathways, cell cycle checkpoint activation, proofreading polymerases, and chromatin structure are ways in which the cell minimizes changes to the genome. During replication, the DNA-damage tolerance pathway allows the replication forks to bypass damage on the template strand. This avoids prolonged replication fork stalling, which can contribute to genome instability. The DNA-damage tolerance pathway includes two subpathways: translesion synthesis and template switch. Post translational modification of PCNA and the histone tails, cell cycle phase, and local DNA structure have all been shown to influence subpathway choice. Chromatin architecture contributes to maintaining genome stability by providing physical protection of the DNA and by regulating DNA-processing pathways. As such, chromatin-binding factors have been implicated in maintaining genome stability. Using Saccharomyces cerevisiae, we examined the role of Spn1 (Suppresses postrecruitment gene number 1), a chromatin-binding and transcription elongation factor, in DNA-damage tolerance. Expression of a mutant allele of SPN1 results in increased resistance to the DNA-damaging agent methyl methanesulfonate, lower spontaneous and damage-induced mutation rates, along with increased chronological life span. We attribute these effects to an increased usage of the template switch branch of the DNA-damage tolerance pathway in the spn1 strain. This provides evidence for a role of wild-type Spn1 in promoting genome instability, as well as having ties to overcoming replication stress and contributing to chronological aging. PMID- 30301739 TI - Radiation Exposure of Premature Infants Beyond the Perinatal Period. AB - OBJECTIVES: To determine the odds of premature compared with term infants exceeding the recommended radiation exposure threshold in the first year after discharge from birth hospitalization. METHODS: In this observational retrospective cohort study, we compared the radiation exposure of premature and term infants between 2008 and 2015 in an urban hospital system. The primary outcome was crossing the radiation exposure threshold of 1 millisievert. We assessed prematurity's effect on this outcome with multivariable logistic regression. RESULTS: In our study, 20 049 term and 2047 preterm infants met inclusion criteria. The population was approximately one-half female, predominantly multiracial or people of color (40% African American and 44% multiracial), and of low socioeconomic status. Premature infants had 2.25 times greater odds of crossing the threshold compared with term infants after adjustment for demographics (95% confidence interval [CI]: 1.66-3.05). Adjustment for complex chronic conditions, which are validated metrics of pediatric chronic illness, attenuated this association; however, premature infants still had 1.58 times greater odds of crossing the threshold (95% CI: 1.16-2.15). When the final model was analyzed by degree of prematurity, very preterm and extremely preterm infants were significantly more likely to cross the threshold (1.85 [95% CI: 1.03 3.32] and 2.53 [95% CI: 1.53-4.21], respectively), whereas late preterm infants were not (1.14 [95% CI: 0.73-1.78]). CONCLUSIONS: Premature infants crossed the recommended radiation threshold more often than term infants in the year after discharge from birth hospitalization. PMID- 30301741 TI - Improving youth mental health supports in Canada. PMID- 30301742 TI - Use of the emergency department as a first point of contact for mental health care by immigrant youth in Canada: a population-based study. AB - BACKGROUND: Emergency department visits as a first point of contact for people with mental illness may reflect poor access to timely outpatient mental health care. We sought to determine the extent to which immigrants use the emergency department as an entryway into mental health services. METHODS: We used linked health and demographic administrative data sets to design a population-based cohort study. We included youth (aged 10-24 yr) with an incident mental health emergency department visit from 2010 to 2014 in Ontario, Canada (n = 118 851). The main outcome measure was an emergency department visit for mental health reasons without prior mental health care from a physician on an outpatient basis. The main predictor of interest was immigrant status (refugee, non-refugee immigrant and non-immigrant). Immigrant-specific predictors included time since migration, and region and country of origin. We used Poisson models to estimate adjusted rate ratios (aRRs) and 95% confidence intervals (CIs). RESULTS: The cohort included 2194 (1.8%) refugee, 6680 (5.6%) non-refugee immigrant and 109 977 (92.5%) nonimmigrant youth. Rates of first mental health contact in the emergency department were higher among refugee (61.3%) and non-refugee immigrant youth (57.6%) than non-immigrant youth (51.3%) (refugee aRR 1.17, 95% CI 1.13 1.21; non-refugee immigrant aRR 1.10, 95% CI 1.08-1.13). Compared with non refugee immigrants, refugees had a higher rate of first mental health contact in the emergency department (aRR 1.06, 95% CI 1.02-1.11). We also observed higher rates among recent versus longer-term immigrants (aRR 1.10, 95% CI 1.05-1.16) and immigrants from Central America (aRR 1.17, 95% CI 1.08-1.26) and Africa (aRR 1.15, 95% CI 1.06-1.24) versus from North America and Western Europe. INTERPRETATION: Immigrant youth are more likely to present with a first mental health crisis to the emergency department than non-immigrants, with variability by region of origin and time since migration. Immigrants may face barriers to access and use of outpatient mental health services from a physician. Efforts are needed to reduce stigma and identify mental health problems early, before crisis, among immigrant populations. PMID- 30301744 TI - Malnutrition in Canadian hospitals.

AB - OBJECTIVES: Extrapyramidal side effects (EPSEs) are serious potentially reversible side effects of antipsychotic and other medications that can cause distress for patients. A core principle of palliative care involves optimising quality of life. If side effects of medications are burdensome, it is imperative that we address this issue. The aim of the study was to determine and describe the burden of EPSEs in a specialist inpatient unit. METHODS: Consenting patients who met inclusion criteria were assessed for EPSE with two validated screening tests, the Modified Simpson-Angus Scale (MSAS) and Barnes Akathisia Rating Scale (BARS). Additional demographic data were collected including medications associated with EPSE, previous history of EPSE and known risk factors that may predispose a patient to EPSE. RESULTS: 43% inpatients met inclusion criteria. At least 66% of patients were taking regular medications associated with EPSE. Of those, 25% were taking >=2 medications associated with EPSE. The MSAS revealed 50% scored <3, 44% scored 3-5% and 6% scored 6-11. Seven patients had at least one 'not rateable score'. In the BARS (sitting+/-standing), 94% scored 0/5 and 6% scored 1/5. 12.5% of participants were able to stand for 2 min to complete the BARS. CONCLUSIONS: 50% screened positive for EPSE. The complete BARS was unsuitable for most participants. The MSAS, while allowing a not rateable score, may underestimate EPSE. The frailty of an inpatient unit population impacts on applicability of screening tools and may therefore underestimate the burden of the problem in this population. Development of a population-specific screening tool warrants further investigation. PMID- 30301753 TI - Palliative care clinicians and online education in India: a survey. AB - BACKGROUND: Whether online resources can facilitate spread of palliative care knowledge and skills in India is an urgent question given few providers and a large, ageing population. OBJECTIVES: We surveyed needs and feasibility regarding e-learning. METHODS: Indian, Australian and North American palliative care experts developed an electronic survey using Qualtrics, emailed to all registrants of the 2017 Indian Association of Palliative Care (IAPC) conference and distributed during the conference. RESULTS: Of 60 respondents (66% men, 60% doctors), most worked in hospitals and had oncology backgrounds, and 35% were from Kerala and Tamil Nadu. Most (90.9%) received palliative care training in India or overseas with 41% trained in a Trivandrum Institute of Palliative Sciences residential course (4-6 weeks). 17% completed the IAPC essential certificate and 22% had undertaken various distance learning courses. Interest in online training was substantial for most aspects of palliative care. CONCLUSION: There was a high level of interest and reported feasibility in taking a case based online course. This pilot survey provides support for online case-based education in India, particularly among physicians. PMID- 30301755 TI - Ipsilesional Motor Cortex Plasticity Participates in Spontaneous Hindlimb Recovery after Lateral Hemisection of the Thoracic Spinal Cord in the Rat. AB - After an incomplete spinal cord injury (SCI) spontaneous motor recovery can occur in mammals, but the underlying neural substrates remain poorly understood. The motor cortex is crucial for skilled motor learning and the voluntary control of movement and is known to reorganize after cortical injury to promote recovery. Motor cortex plasticity has also been shown to parallel the recovery of forelimb function after cervical SCI, but whether cortical plasticity participates in hindlimb recovery after SCI remains unresolved. Using intracortical microstimulation (ICMS) mapping, behavioral and cortical inactivation techniques in the female Long-Evans rat, we evaluated the spontaneous cortical mechanisms of hindlimb motor recovery 1-5 weeks after lateral hemisection of the thoracic (T8) spinal cord that ablated the crossed corticospinal tract (CST) from the contralesional motor cortex while sparing the majority of the CST from the ipsilesional motor cortex. Hemisection initially impaired hindlimb motor function bilaterally but significant recovery occurred during the first 3 weeks. ICMS revealed time-dependent changes in motor cortex organization, characterized by a chronic abolishment of hindlimb motor representation in the contralesional motor cortex and the development of transient bilateral hindlimb representation in the ipsilesional motor cortex 3 weeks after hemisection, when significant behavioral recovery occurred. Consistently, reversible inactivation of the ipsilesional, but not the contralesional motor cortex, during skilled ladder walking 3 weeks after hemisection reinstated deficits in both hindlimbs. These findings indicate that the ipsilesional motor cortex transiently reorganizes after lateral hemisection of the thoracic spinal cord to support recovery of hindlimb motor function.SIGNIFICANCE STATEMENT Partial motor recovery can occur after an incomplete spinal cord injury and is hypothesized to result from the reorganization of spared descending motor pathways. The motor cortex is crucial for the control of voluntary movement and contains topographical movement representations (motor maps) that are highly plastic. We examined the organization of hindlimb motor maps bilaterally after a lateral hemisection of the spinal cord to show that while motor maps are abolished in the deefferented cortex, the spared ipsilesional cortex transiently reorganizes to gain a representation of the affected hindlimb after injury that relates to recovery. This finding demonstrates that plasticity in the ipsilesional motor cortex at early time points after spinal cord hemisection is initially important to support motor recovery. PMID- 30301754 TI - Tropomodulin Isoform-Specific Regulation of Dendrite Development and Synapse Formation. AB - Neurons of the CNS elaborate highly branched dendritic arbors that host numerous dendritic spines, which serve as the postsynaptic platform for most excitatory synapses. The actin cytoskeleton plays an important role in dendrite development and spine formation, but the underlying mechanisms remain incompletely understood. Tropomodulins (Tmods) are a family of actin-binding proteins that cap the slow-growing (pointed) end of actin filaments, thereby regulating the stability, length, and architecture of complex actin networks in diverse cell types. Three members of the Tmod family, Tmod1, Tmod2, and Tmod3 are expressed in the vertebrate CNS, but their function in neuronal development is largely unknown. In this study, we present evidence that Tmod1 and Tmod2 exhibit distinct roles in regulating spine development and dendritic arborization, respectively. Using rat hippocampal tissues from both sexes, we find that Tmod1 and Tmod2 are expressed with distinct developmental profiles: Tmod2 is expressed early during hippocampal development, whereas Tmod1 expression coincides with synaptogenesis. We then show that knockdown of Tmod2, but not Tmod1, severely impairs dendritic branching. Both Tmod1 and Tmod2 are localized to a distinct subspine region where they regulate local F-actin stability. However, the knockdown of Tmod1, but not Tmod2, disrupts spine morphogenesis and impairs synapse formation. Collectively, these findings demonstrate that regulation of the actin cytoskeleton by different members of the Tmod family plays an important role in distinct aspects of dendrite and spine development.SIGNIFICANCE STATEMENT The Tropomodulin family of molecules is best known for controlling the length and stability of actin myofilaments in skeletal muscles. While several Tropomodulin members are expressed in the brain, fundamental knowledge about their role in neuronal function is limited. In this study, we show the unique expression profile and subcellular distribution of Tmod1 and Tmod2 in hippocampal neurons. While both Tmod1 and Tmod2 regulate F-actin stability, we find that they exhibit isoform specific roles in dendrite development and synapse formation: Tmod2 regulates dendritic arborization, whereas Tmod1 is required for spine development and synapse formation. These findings provide novel insight into the actin regulatory mechanisms underlying neuronal development, thereby shedding light on potential pathways disrupted in a number of neurological disorders. PMID- 30301756 TI - Insensitivity to Pain upon Adult-Onset Deletion of Nav1.7 or Its Blockade with Selective Inhibitors. AB - Strong human genetic evidence points to an essential contribution of the voltage gated sodium channel Nav1.7 to pain sensation: loss of Nav1.7 function leads to congenital insensitivity to pain, whereas gain-of-function mutations in the SCN9A gene that encodes Nav1.7 cause painful neuropathies, such as inherited erythromelalgia, a syndrome characterized by episodic spontaneous pain. Selective Nav1.7 channel blockers thus hold promise as potential painkillers with improved safety and reduced unwanted side effects compared with existing therapeutics. To determine the maximum effect of a theoretically perfectly selective Nav1.7 inhibitor, we generated a tamoxifen-inducible KO mouse model enabling genetic deletion of Nav1.7 from adult mice. Electrophysiological recordings of sensory neurons from these mice following tamoxifen injection demonstrated the loss of Nav1.7 channel current and the resulting decrease in neuronal excitability of small-diameter neurons. We found that behavioral responses to most, but surprisingly not all, modalities of noxious stimulus are abolished following adult deletion of Nav1.7, pointing toward indications where Nav1.7 blockade should be efficacious. Furthermore, we demonstrate that isoform-selective acylsulfonamide Nav1.7 inhibitors show robust analgesic and antinociceptive activity acutely after a single dose in mouse pain models shown to be Nav1.7 dependent. All experiments were done with both male and female mice. Collectively, these data expand the depth of knowledge surrounding Nav1.7 biology as it relates to pain, and provide preclinical proof of efficacy that lays a clear path toward translation for the therapeutic use of Nav1.7-selective inhibitors in humans.SIGNIFICANCE STATEMENT Loss-of-function mutations in the sodium channel Nav1.7 cause congenital insensitivity to pain in humans, making Nav1.7 a top target for novel pain drugs. Targeting Nav1.7 selectively has been challenging, however, in part due to uncertainties in which rodent pain models are dependent on Nav1.7. We have developed and characterized an adult-onset Nav1.7 KO mouse model that allows us to determine the expected effects of a theoretically perfect Nav1.7 blocker. Importantly, many commonly used pain models, such as mechanical allodynia after nerve injury, appear to not be dependent on Nav1.7 in the adult. By defining which models are Nav1.7 dependent, we demonstrate that selective Nav1.7 inhibitors can approximate the effects of genetic loss of function, which previously has not been directly established. PMID- 30301757 TI - A Multicomponent Neuronal Response Encodes the Larval Decision to Pupariate upon Amino Acid Starvation. AB - Organisms need to coordinate growth with development, particularly in the context of nutrient availability. Thus, multiple ways have evolved to survive extrinsic nutrient deprivation during development. In Drosophila, growth occurs during larval development. Larvae are thus critically dependent on nutritional inputs; but after critical weight, they pupariate even when starved. How nutrient availability is coupled to the internal metabolic state for the decision to pupariate needs better understanding. We had earlier identified glutamatergic interneurons in the ventral ganglion that regulate pupariation on a protein deficient diet. Here we report that Drosophila third instar larvae (either sex) sense arginine to evaluate their nutrient environment using an amino acid transporter Slimfast. The glutamatergic interneurons integrate external protein availability with internal metabolic state through neuropeptide signals. IP3 mediated calcium release and store-operated calcium entry are essential in these glutamatergic neurons for such integration and alter neuronal function by reducing the expression of multiple ion channels.SIGNIFICANCE STATEMENT Coordinating growth with development, in the context of nutrient availability is a challenge for all organisms in nature. After attainment of "critical weight," insect larvae can pupariate, even in the absence of nutrition. Mechanism(s) that stimulate appropriate cellular responses and allow normal development on a nutritionally deficient diet remain to be understood. Here, we demonstrate that nutritional deprivation, in postcritical weight larvae, is sensed by special sensory neurons through an amino acid transporter that detects loss of environmental arginine. This information is integrated by glutamatergic interneurons with the internal metabolic state through neuropeptide signals. These glutamatergic interneurons require calcium-signaling-regulated expression of a host of neuronal channels to generate complex calcium signals essential for pupariation on a protein-deficient diet. PMID- 30301758 TI - The Hippocampal Film Editor: Sensitivity and Specificity to Event Boundaries in Continuous Experience. AB - The function of the human hippocampus is normally investigated by experimental manipulation of discrete events. Less is known about what triggers hippocampal activity during more naturalistic, continuous experience. We hypothesized that the hippocampus would be sensitive to the occurrence of event boundaries, that is, moments in time identified by observers as a transition between events. To address this, we analyzed functional MRI data from two groups: one (n = 253, 131 female) who viewed an 8.5 min film and another (n = 15, 6 female) who viewed a 120 min film. We observed a strong hippocampal response at boundaries defined by independent observers, which was modulated by boundary salience (the number of observers that identified each boundary). In the longer film, there were sufficient boundaries to show that this modulation remained after covarying out a large number of perceptual factors. This hypothesis-driven approach was complemented by a data-driven approach, in which we identified hippocampal events as moments in time with the strongest hippocampal activity. The correspondence between these hippocampal events and event boundaries was highly significant, revealing that the hippocampal response is not only sensitive, but also specific to event boundaries. We conclude that event boundaries play a key role in shaping hippocampal activity during encoding of naturalistic events.SIGNIFICANCE STATEMENT Recent years have seen the field of human neuroscience research transitioning from experiments with simple stimuli to the study of more complex and naturalistic experience. Nonetheless, our understanding of the function of many brain regions, such as the hippocampus, is based primarily on the study of brief, discrete events. As a result, we know little of what triggers hippocampal activity in real-life settings when we are exposed to a continuous stream of information. When does the hippocampus "decide" to respond during the encoding of naturalistic experience? We reveal here that hippocampal activity measured by fMRI during film watching is both sensitive and specific to event boundaries, identifying a potential mechanism whereby event boundaries shape experience by modulation of hippocampal activity. PMID- 30301760 TI - Degranulation of gastrointestinal mast cells contributes to hepatic ischemia reperfusion injury in mice. AB - The pathological changes following liver damage, including those caused by ischemia and reperfusion (I/R), are closely related to gastrointestinal dysregulation. Mast cells (MCs) are tissue-resident immune cells abundant in the gastrointestinal system that play diverse roles. In view of the characteristic localization of MCs around the microvasculature, we hypothesized that a stimulus specific set of mediators released through degranulation of gastrointestinal MCs, which are enriched in hepatic sinusoids via the hepatic system, subsequently participate in associated pathological development within the liver. To elucidate the biological role of gastrointestinal MC granules in liver damage, we employed an experimental liver I/R model that allows conditional ablation of MCs. Marked degranulation was detected during I/R, which showed a significant positive correlation with liver damage. Our experiments further disclosed that MC degranulation primarily enhanced the cycle of inflammatory damage in I/R liver consisting of liver sinusoidal endothelial cell death, neutrophil infiltration, and formation of a neutrophil extracellular trap, with a concomitant increase in adhesion molecules, inflammatory cytokines, chemokines, and oxidative stress. Based on the collective results, we propose that suppression of activity or number of MCs may present an effective strategy for protection against hepatic I/R injury. PMID- 30301759 TI - Unilateral, 3D Arm Movement Kinematics Are Encoded in Ipsilateral Human Cortex. AB - There is increasing evidence that the hemisphere ipsilateral to a moving limb plays a role in planning and executing movements. However, the exact relationship between cortical activity and ipsilateral limb movements is uncertain. We sought to determine whether 3D arm movement kinematics (speed, velocity, and position) could be decoded from cortical signals recorded from the hemisphere ipsilateral to the moving limb. By having invasively monitored patients perform unilateral reaches with each arm, we also compared the encoding of contralateral and ipsilateral limb kinematics from a single cortical hemisphere. In four motor intact human patients (three male, one female) implanted with electrocorticography electrodes for localization of their epileptic foci, we decoded 3D movement kinematics of both arms with accuracies above chance. Surprisingly, the spatial and spectral encoding of contralateral and ipsilateral limb kinematics was similar, enabling cross-prediction of kinematics between arms. These results clarify our understanding that the ipsilateral hemisphere robustly contributes to motor execution and supports that the information of complex movements is more bihemispherically represented in humans than has been previously understood.SIGNIFICANCE STATEMENT Although limb movements are traditionally understood to be driven by the cortical hemisphere contralateral to a moving limb, movement-related neural activity has also been found in the ipsilateral hemisphere. This study provides the first demonstration that 3D arm movement kinematics can be decoded from human electrocorticographic signals ipsilateral to the moving limb. Surprisingly, the spatial and spectral encoding of contralateral and ipsilateral limb kinematics was similar. The finding that specific kinematics are encoded in the ipsilateral hemisphere demonstrates that the ipsilateral hemisphere contributes to the execution of unilateral limb movements, improving our understanding of motor control. Additionally, the bihemisheric representation of voluntary movements has implications for the development of neuroprosthetic systems for reaching and for neurorehabilitation strategies following cortical injuries. PMID- 30301761 TI - Novel treatment avenues for uterine leiomyoma: a new implication for endothelin? AB - Cysteine-rich angiogenic inducer 61 (CYR61), an angiogenic factor whose expression is decreased in fibroids. The aim of the present study was to determine if CYR61 secretion in smooth muscle cells (SMCs) is regulated by hypoxia and through the endothelin A (ETA) receptor. SMCs from fibroids (fSMC) and the adjacent myometrium smooth muscle cells (mSMCs) were extracted from ten women undergoing hysterectomy for uterine fibroids and cultured with or without 1.0 uM of an ETA receptor antagonist for 24 h under either normal or hypoxic oxygen conditions. Cellular secretion of endothelin-1 (ET-1) and CYR61 were measured via enzyme linked immunosorbent assay in the cell culture media. SMCs were collected to determine cell proliferation and CYR61 protein expression via Western blot. ET-1 secretion was significantly increased in fSMC and was decreased with blockade of the ETA receptor under both normoxia (P=0.0004) and hypoxia (P=0.008). CYR61 expression was decreased in fSMCs and significantly increased with blockade of the ETA receptor under hypoxia (P=0.04). Cell proliferation decreased with ETA blockade under normoxia (P=0.0001) and hypoxia (P=0.001). These results suggest that suppression of CYR61 secretion in fSMC is regulated by the ET-1 and that blockade with ETA could be considered for a future treatment option.

PMID- 30301763 TI - Sociodemographic correlates of eating disorder subtypes among men and women in France, with a focus on age. AB - BACKGROUND: On the population level, the association of age and other sociodemographic factors with eating disorders (ED) is unclear. METHODS: We used cross-sectional data from the French general population-based NutriNet-Sante e cohort (n=49 603 adults; 76.3% women; mean age=50.4+/-14.6 years). ED were evaluated in 2014 with the 5-item SCOFF screening questionnaire and the Expali algorithmic tool. Likely cases of restrictive, bulimic, hyperphagic and other ED were the dependent variables. Age, marital status, education, occupation, physical activity and smoking were the independent variables. Associations were estimated via gender-stratified multivariable polytomous logistic regression. RESULTS: Among women, age displayed inverse linear associations with both restrictive and bulimic ED, underscoring 18-25 years as the most vulnerable period (adjusted OR=3.37, 95% CI: 2.24 to 5.08 for restrictive ED; adjusted OR=2.98, 95% CI: 2.37 to 3.74 for bulimic ED, respectively). A similar association was observed in men regarding bulimic ED. In women, age was not associated with hyperphagic ED for which living alone, low education, low physical activity, being a homemaker/disabled/unemployed/retired, a manual worker or a former/current smoker had increased importance. In men, 18-39 years emerged as the least vulnerable period regarding hyperphagic ED (adjusted OR=0.74, 95% CI: 0.56 to 0.99). Across gender, having postsecondary education had significant inverse associations with all except restrictive ED, whereas being a student had a significant positive association with restrictive ED. CONCLUSIONS: The findings support gender-specific associations of age with four ED subtypes and could inform future prevention initiatives targeting specific ED among specific age groups.

PMID- 30301764 TI - Contrasted trends in health-related quality of life across gender, age categories and work status in France, 1995-2016: repeated population-based cross-sectional surveys using the SF-36. AB - BACKGROUND: Interest in monitoring health-related quality of life (HRQoL) in general populations has increased in the past 20 years, reinforced by population ageing and repeated economic crises. This study aims to identify temporal trends in HRQoL in France between 1995 and 2016 and to assess disparities according to demographic and socioeconomic characteristics. METHODS: Data from repeated population-based cross-sectional surveys conducted in 1995, 2003 and 2016 were used. HRQoL was measured using the Medical Outcomes Study 36-item Short Form (SF 36) questionnaire. RESULTS: A substantial decrease in score was observed between 1995 and 2016 for both genders in almost all subscales of the SF-36, with the largest decrease being in the mental health dimension for men. However, the age group 18-54 years were the most affected with persistent negative or even worsening trends in HRQoL. The largest decreases were among men aged 45-54 years and women aged 35-44 years in most dimensions, and among the age group 18-24 years in vitality. Conversely, an overall improvement was noted among the age group 65-84 years. People in employment were more affected than the unemployed by the decline in several HRQoL dimensions. CONCLUSION: A general decline in HRQoL was found between 1995 and 2016 in the French population, but with wide disparities in trends between age groups. Young and especially middle-aged, employed people exhibited persistent negative and worsening trends. Consistent with evidence from traditional mental health morbidity and mortality indicators, our findings raise questions about the potential influence of macro-socioeconomic factors, especially the 2008 crisis; these observations deserve special attention from health policy-makers. PMID- 30301766 TI - Proliferating cell nuclear antigen interacts with the CRL4 ubiquitin ligase subunit CDT2 in DNA synthesis-induced degradation of CDT1. AB - During DNA replication or repair, the DNA polymerase cofactor, proliferating cell nuclear antigen (PCNA), homotrimerizes and encircles the replicating DNA, thereby acting as a DNA clamp that promotes DNA polymerase processivity. The formation of the PCNA trimer is also essential for targeting the replication- licensing protein, chromatin-licensing and DNA replication factor 1 (CDT1), for ubiquitin dependent proteolysis to prevent chromosomal DNA re-replication. CDT1 uses its PCNA-interacting peptide box (PIP box) to interact with PCNA, and the CRL4 E3 ubiquitin ligase subunit CDT2 is recruited through the formation of PCNA-CDT1 complexes. However, it remains unclear how CDT1 and many other PIP box-containing proteins are marked for degradation by the CRL4CDT2 ubiquitin ligase during DNA replication or damage. Here, using recombinant protein expression coupled with site-directed mutagenesis, we report that CDT2 and PCNA directly interact and this interaction depends on the presence of a highly conserved, C-terminal PIP box-like region in CDT2. Deletion or mutation of this region abolished the CDT2 PCNA interaction between CDT2 and PCNA both in vitro and in vivo. Moreover, PCNA dependent CDT1 degradation in response to DNA damage and replication during the cell cycle requires an intact PIP box in CDT2. The requirement of the PIP boxes in both CDT2 and its substrate CDT1 suggests that the formation of the PCNA trimeric clamp around DNA during DNA replication and repair may bring together CDT1 and CRL4CDT2 ubiquitin E3 ligase to target CDT1 for proteolysis in a DNA synthesis-dependent manner. PMID- 30301767 TI - Three structurally and functionally distinct beta-glucuronidases from the human gut microbe Bacteroides uniformis. AB - The glycoside hydrolases encoded by the human gut microbiome play an integral role in processing a variety of exogenous and endogenous glycoconjugates. Here we present three structurally and functionally distinct beta-glucuronidase (GUS) glycoside hydrolases from a single human gut commensal microbe, Bacteroides uniformis We show using nine crystal structures, biochemical, and biophysical data that whereas these three proteins share similar overall folds, they exhibit different structural features that create three structurally and functionally unique enzyme active sites. Notably, quaternary structure plays an important role in creating distinct active site features that are hard to predict via structural modeling methods. The enzymes display differential processing capabilities toward glucuronic acid-containing polysaccharides and SN-38-glucuronide, a metabolite of the cancer drug irinotecan. We also demonstrate that GUS-specific and nonselective inhibitors exhibit varying potencies toward each enzyme. Together, these data highlight the diversity of GUS enzymes within a single Bacteroides gut commensal and advance our understanding of how structural details impact the specific roles microbial enzymes play in processing drug-glucuronide and glycan substrates. PMID- 30301768 TI - Inhibition of monoacylglycerol lipase, an anti-inflammatory and antifibrogenic strategy in the liver. AB - OBJECTIVE: Sustained inflammation originating from macrophages is a driving force of fibrosis progression and resolution. Monoacylglycerol lipase (MAGL) is the rate-limiting enzyme in the degradation of monoacylglycerols. It is a proinflammatory enzyme that metabolises 2-arachidonoylglycerol, an endocannabinoid receptor ligand, into arachidonic acid. Here, we investigated the impact of MAGL on inflammation and fibrosis during chronic liver injury. DESIGN: C57BL/6J mice and mice with global invalidation of MAGL (MAGL -/- ), or myeloid specific deletion of either MAGL (MAGLMye-/-), ATG5 (ATGMye-/-) or CB2 (CB2Mye-/ ), were used. Fibrosis was induced by repeated carbon tetrachloride (CCl4) injections or bile duct ligation (BDL). Studies were performed on peritoneal or bone marrow-derived macrophages and Kupffer cells. RESULTS: MAGL -/- or MAGLMye-/ mice exposed to CCl4 or subjected to BDL were more resistant to inflammation and fibrosis than wild-type counterparts. Therapeutic intervention with MJN110, an MAGL inhibitor, reduced hepatic macrophage number and inflammatory gene expression and slowed down fibrosis progression. MAGL inhibitors also accelerated fibrosis regression and increased Ly-6Clow macrophage number. Antifibrogenic effects exclusively relied on MAGL inhibition in macrophages, since MJN110 treatment of MAGLMye-/- BDL mice did not further decrease liver fibrosis. Cultured macrophages exposed to MJN110 or from MAGLMye-/- mice displayed reduced cytokine secretion. These effects were independent of the cannabinoid receptor 2, as they were preserved in CB2Mye-/- mice. They relied on macrophage autophagy, since anti-inflammatory and antifibrogenic effects of MJN110 were lost in ATG5Mye /- BDL mice, and were associated with increased autophagic flux and autophagosome biosynthesis in macrophages when MAGL was pharmacologically or genetically inhibited. CONCLUSION: MAGL is an immunometabolic target in the liver. MAGL inhibitors may show promising antifibrogenic effects during chronic liver injury.

PMID- 30301765 TI - The Streptococcus pyogenes Shr protein captures human hemoglobin using two structurally unique binding domains. AB - In order to proliferate and mount an infection, many bacterial pathogens need to acquire iron from their host. The most abundant iron source in the body is the oxygen transporter hemoglobin (Hb). Streptococcus pyogenes, a potentially lethal human pathogen, uses the Shr protein to capture Hb on the cell surface. Shr is an important virulence factor, yet the mechanism by which it captures Hb and acquires its heme is not well-understood. Here, we show using NMR and biochemical methods that Shr binds Hb using two related modules that were previously defined as domains of unknown function (DUF1533). These hemoglobin-interacting domains (HIDs), called HID1 and HID2, are autonomously folded and independently bind Hb. The 1.5 A resolution crystal structure of HID2 revealed that it is a structurally unique Hb-binding domain. Mutagenesis studies revealed a conserved tyrosine in both HIDs that is essential for Hb binding. Our biochemical studies indicate that HID2 binds Hb with higher affinity than HID1 and that the Hb tetramer is engaged by two Shr receptors. NMR studies reveal the presence of a third autonomously folded domain between HID2 and a heme-binding NEAT1 domain, suggesting that this linker domain may position NEAT1 near Hb for heme capture. PMID- 30301770 TI - Rare cause of rectal stenosis in a patient with long-term use of Infliximab and Mercaptopurine for ulcerative colitis. AB - QUESTION: A 58-year-old, non-smoker male patient with no family history was followed up since 2002 for ulcerative colitis (UC) located in the rectosigmoid. He was initially treated by salicylates alone until November 2008. Mercaptopurine was started in August 2009 for steroid dependence with primary failure despite adequate 6 thioguanine nucleotides (6 TGN) level. He was included in February 2010 in the PURSUIT trial testing Golimumab with only partial response. A combination therapy with Mercaptopurine and Infliximab was then started in December 2010 with a long-term clinical, biological and endoscopic steroid-free remission. A pan-chromoendoscopy performed in June 2016 showed a complete mucosal healing with no histological activity or dysplasia on multiple random biopsies. Regular monitoring of Infliximab trough levels and 6-TGN were appropriate. A rectosigmoidoscopy was carried in September 2017 for a relapse (figure 1A), scored UCEIS 3. Rectal biopsies showed a polymorphic inflammatory infiltrate with no dysplasia. Bacterial cultures were negative. A new Infliximab infusion was administered without clinical improvement. He was hospitalised in October 2017 for poor general state, fever and persistent bloody diarrhoea. A CT scan of the chest, abdomen and pelvis found multiple mesenteric and peri-aortic lymphadenopathies, peritoneal infiltration with bilateral pyelocaliceal dilatation and major rectal thickening (figure 1B). The rectosigmoidoscopy revealed a stenosis from 5 to 20 cm from the anal verge passable by the fiberscope only (figure 1C). Biopsies were performed (figure 1D).gutjnl;gutjnl 2018-317069v1/F1F1F1Figure 1(A) Endoscopic view of the rectosigmoid (27 September 2017).

PMID- 30301773 TI - The Mitochondrial Endonuclease M20 Participates in the Down-regulation of Mitochondrial DNA in Pollen Cells. AB - Maintaining the appropriate number of mitochondrial DNA (mtDNA) molecules is crucial for supporting mitochondrial metabolism and function in both plant and animal cells. For example, a substantial decrease in mtDNA levels occurs as a key part of pollen development. The molecular mechanisms regulating mtDNA copy number are largely unclear, particularly with regard to those that reduce mtDNA levels. Here, we identified and purified a 20 kD endonuclease, M20, from maize (Zea mays) pollen mitochondria. We found M20 to be an H-N-H/N nuclease that degrades linear and circular DNA in the presence of Mg2+ or Mn2+. Arabidopsis thaliana AtM20, which shared high sequence similarity with maize M20, localized to the mitochondria, had a similar H-N-H/N structure, and degraded both linear and circular DNA. AtM20 transcript levels increased during pollen development, in parallel with a rapid reduction in mtDNA. Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) genome editing techniques were used to generate knockout lines of AtM20 (atm20), which exhibited a significant delay in the reduction in mtDNA levels in pollen vegetative cells but normal mtDNA levels in somatic cells. The delayed reduction in pollen mtDNA levels was rescued by the transgenic expression of AtM20 in atm20 plants. This study thus uncovers an endonucleolytic DNase in plant mitochondria and its crucial role in reducing mtDNA levels, pointing to the complex mechanism regulating mtDNA levels in plants. PMID- 30301774 TI - A Musashi Splice Variant and its Interaction Partners Influence Temperature Acclimation in Chlamydomonas. AB - Microalgae contribute significantly to carbon fixation on Earth. Global warming influences their physiology and growth rates. To understand algal short-term acclimation and adaptation to changes in ambient temperature, it is essential to identify and characterize the molecular components that sense small temperature changes, as well as the downstream signaling networks and physiological responses. Here, we used the green biflagellate alga Chlamydomonas reinhardtii as a model system to study responses to temperature. We report that an RNA recognition motif (RRM)-containing RNA-binding protein, Musashi, occurs in 25 putative splice variants. These variants bear one, two, and three RRM domain(s), or even lack RRM domains. The most abundant Musashi variant, 12, with a molecular weight of 60 kDa, interacts with two clock-relevant members of RNA metabolism, the subunit C3 of the RNA-binding protein CHLAMY1 and the 5'-3' exoribonuclease XRN1. These proteins are able to integrate temperature information by up- or down regulation of their protein levels in cells grown at low (18{degree sign}C) or high (28{degree sign}C) temperature. We further show that the 60-kDa Musashi variants with three RRM-domains can bind to (UG)7-repeat containing RNAs and are up-regulated in cells grown at a higher temperature during early night. Intriguingly, the 60-kDa Musashi variant 12, as well as C3 and XRN1, confer thermal acclimation to C. reinhardtii, as shown with mutant lines. Our data suggest that these three proteins of the RNA metabolism machinery are key members of the thermal signaling network in C. reinhardtii. PMID- 30301775 TI - RNA Polymerase II read-through promotes expression of neighboring genes in SAL1 PAP-XRN retrograde signaling. AB - In plants, the molecular function(s) of the nuclear localised 5'-3' EXORIBONUCLEASES (XRNs) are unclear; however, their activity is reported to have a significant effect on gene expression and SAL1-mediated retrograde signaling. Using Parallel Analysis of RNA Ends (PARE) we documented a dramatic increase in uncapped RNA substrates of the XRNs in both sal1 and xrn2xrn3 mutants. We found that a major consequence of reducing SAL1 or XRN activity was RNA Polymerase II (Pol II) 3' read-through. This occurred at 72% of expressed genes, demonstrating a major genome-wide role for the XRN-torpedo model of transcription termination in Arabidopsis. Read-through is speculated to have a negative effect on transcript abundance; however, we did not observe this. Rather, we identified a strong association between read-though and increased transcript abundance of tandemly orientated downstream genes, strongly correlated with the proximity (<1,000 bp) and expression of the upstream gene. We observed read-though in the proximity of 903 genes upregulated in the sal1-8 retrograde signaling mutant; thus, this phenomenon may directly account for up to 23% of genes upregulated in sal1-8. Using APX2 and AT5G43770 as exemplars, we genetically uncoupled read through loci from downstream genes to validate the principle of read-through mediated mRNA regulation, providing one mechanism by which an ostensibly post transcriptional exoribonuclease that targets uncapped RNAs could modulate gene expression. PMID- 30301776 TI - Polyploidy affects plant growth and alters cell wall composition. AB - Polyploidization has played a key role in plant breeding and crop improvement. Although its potential to increase biomass yield is well described, the effect of polyploidization on biomass composition has largely remained unexplored. Here, we generated a series of Arabidopsis (Arabidopsis thaliana) plants with different somatic ploidy levels (2n, 4n, 6n, and 8n) and performed rigorous phenotypic characterization. Kinematic analysis showed that polyploids developed slower compared to diploids; however, tetra- and hexaploids, but not octaploids, generated larger rosettes due to delayed flowering. In addition, morphometric analysis of leaves showed that polyploidy affected epidermal pavement cells, with increased cell size and reduced cell number per leaf blade with incrementing ploidy. However, the inflorescence stem dry weight was highest in tetraploids. Cell wall characterization revealed that the basic somatic ploidy level negatively correlated with lignin and cellulose content, and positively correlated with matrix polysaccharide content (i.e. hemicellulose and pectin) in the stem tissue. In addition, higher ploidy plants displayed altered sugar composition. Such effects were linked to the delayed development of polyploids. Moreover, the changes in polyploid cell wall composition promoted saccharification yield. The results of this study indicate that induction of polyploidy is a promising breeding strategy to further tailor crops for biomass production. PMID- 30301777 TI - Mesenchymal stem cell mechanotransduction is cAMP dependent and regulated by adenylyl cyclase 6 and the primary cilium. AB - Mechanical loading is a potent stimulus of bone adaptation, requiring the replenishment of the osteoblast from a progenitor population. One such progenitor is the mesenchymal stem cell (MSC), which undergoes osteogenic differentiation in response to oscillatory fluid shear. Yet, the mechanism mediating stem cell mechanotransduction, and thus the potential to target this therapeutically, is poorly understood. In this study, we demonstrate that MSCs utilise cAMP as a second messenger in mechanotransduction, which is required for flow-mediated increases in osteogenic gene expression. Furthermore, we demonstrate that this mechanosignalling is dependent on the primary cilium and the ciliary localised adenylyl cyclase 6. Finally, we also demonstrate that this mechanotransduction mechanism can be targeted therapeutically to enhance cAMP signalling and early osteogenic signalling, mimicking the beneficial effect of physical loading. Our findings therefore demonstrate a novel mechanism of MSC mechanotransduction that can be targeted therapeutically, demonstrating a potential mechanotherapeutic for bone-loss diseases such as osteoporosis.This article has an associated First Person interview with the first author of the paper. PMID- 30301779 TI - TM9SF4 levels determine sorting of transmembrane domains in the early secretory pathway. AB - Previous studies have shown that TM9SF4 interacts with glycine-rich transmembrane domains (TMDs) and promotes their surface localization, presumably by escorting them along the secretory pathway. Here, we delineated the role of TM9 proteins in the sorting of TMDs. Our results indicate that TM9SF4 interacts with and sorts a variety of TMDs. In human embryonic kidney (HEK) cells, a TMD carrying a positively charged residue (T-R1) or a negatively charged residue (T-D1) was localized to the endoplasmic reticulum (ER), but partially relocated to the Golgi complex upon overexpression of TM9SF4. These results show that TM9SF4 controls the sorting of TMDs at the ER-Golgi interface. Remarkably, sorting of T-R1 in HCT116 cells was different from that in HEK cells: in HCT116 cells, a substantial fraction of T-R1 was localized to the Golgi complex, and it was relocated to the ER by genetic ablation of TM9SF4. This observation indicates that TM9SF4 sorting activity differs in HEK and HCT116 cells, resulting in different sorting of TMDs in these two cell types. Although TM9SF1 associated with several TMDs, it did not visibly alter their intracellular transport in the secretory pathway and may function in other intracellular transport pathways. PMID- 30301780 TI - Mechanisms of integrin alphaVbeta5 clustering in flat clathrin lattices. AB - The family of integrin transmembrane receptors is essential for the normal function of multicellular organisms by facilitating cell-extracellular matrix adhesion. The vitronectin-binding integrin alphaVbeta5 localizes to focal adhesions (FAs) as well as poorly characterized flat clathrin lattices (FCLs). Here, we show that, in human keratinocytes, alphaVbeta5 is predominantly found in FCLs, and formation of the alphaVbeta5-containing FCLs requires the presence of vitronectin as ligand, Ca2+, and the clathrin adaptor proteins ARH (also known as LDLRAP1), Numb and EPS15/EPS15L1. Integrin chimeras, containing the extracellular and transmembrane domains of beta5 and the cytoplasmic domains of beta1 or beta3, almost exclusively localize in FAs. Interestingly, lowering actomyosin-mediated contractility promotes integrin redistribution to FLCs in an integrin tail dependent manner, while increasing cellular tension favors alphaVbeta5 clustering in FAs. Our findings strongly indicate that clustering of integrin alphaVbeta5 in FCLs is dictated by the beta5 subunit cytoplasmic domain, cellular tension and recruitment of specific adaptor proteins to the beta5 subunit cytoplasmic domains. PMID- 30301778 TI - Super-resolution imaging of live sperm reveals dynamic changes of the actin cytoskeleton during acrosomal exocytosis. AB - Filamentous actin (F-actin) is a key factor in exocytosis in many cell types. In mammalian sperm, acrosomal exocytosis (denoted the acrosome reaction or AR), a special type of controlled secretion, is regulated by multiple signaling pathways and the actin cytoskeleton. However, the dynamic changes of the actin cytoskeleton in live sperm are largely not understood. Here, we used the powerful properties of SiR-actin to examine actin dynamics in live mouse sperm at the onset of the AR. By using a combination of super-resolution microscopy techniques to image sperm loaded with SiR-actin or sperm from transgenic mice containing Lifeact-EGFP, six regions containing F-actin within the sperm head were revealed. The proportion of sperm possessing these structures changed upon capacitation. By performing live-cell imaging experiments, we report that dynamic changes of F actin during the AR occur in specific regions of the sperm head. While certain F actin regions undergo depolymerization prior to the initiation of the AR, others remain unaltered or are lost after exocytosis occurs. Our work emphasizes the utility of live-cell nanoscopy, which will undoubtedly impact the search for mechanisms that underlie basic sperm functions.This article has an associated First Person interview with the first author of the paper. PMID- 30301781 TI - Rab34 small GTPase is required for Hedgehog signaling and an early step of ciliary vesicle formation in mouse. AB - The primary cilium is a microtubule-based organelle that protrudes from the cell surface and plays essential roles in embryonic development. Ciliogenesis begins with the successive fusion of preciliary vesicles to form ciliary vesicles, which then dock onto the distal end of the mother centriole. Rab proteins have been linked to cilia formation in cultured cells, but not yet in vivo In the present study, we demonstrate that endocytic recycling protein Rab34 localizes to cilia, and that its mutation results in significant decrease of ciliogenesis in both cultured cells and mice. Rab34 is required for the successive fusion of preciliary vesicles to generate ciliary vesicles and for the migration of the mother centriole from perinuclear region to plasma membrane. We also show that Rab34 mutant mice exhibit polydactyly, and cleft-lip and -palate. These phenotypes are consistent with observations that nonciliated Rab34 mutant cells fail to respond to Hedgehog signaling and that processing of full-length Gli3 to its C-terminally truncated form is reduced in Rab34 mutant embryos. Therefore, Rab34 is required for an early step of ciliary vesicle formation and Hh signaling in vivo This article has an associated First Person interview with the first author of the paper. PMID- 30301783 TI - The RHEB-mTOR axis regulates expression of Tf2 transposons in fission yeast. AB - The human TSC2 gene, mutations in which predispose individuals to the disease tuberous sclerosis complex (TSC), encodes a GTPase-activating protein for the GTPase RHEB. Loss of TSC2 results in constitutive activation of RHEB and its target mammalian target of rapamycin (mTOR). We have previously reported that fission yeast (Schizosaccharomyces pombe) Tf2 retrotransposons (hereafter Tf2s) are abnormally induced upon nitrogen starvation in cells lacking the tsc2+ gene (Deltatsc2), a homolog of the human TSC2 gene, and in cells with a dominant active mutation in the fission yeast RHEB GTPase (rhb1-DA4). We report here that induction of Tf2s in these mutants is suppressed upon overexpression of the cgs2+ gene, which encodes a cAMP-specific phosphodiesterase, or upon deletion of components in the glucose/cAMP signaling pathway, namely Cyr1, Pka1, Tor1 and the stress-activated transcription factor Atf1. The results suggest that the glucose/cAMP signaling pathway is downregulated when cells are starved for nitrogen. We also show that Tf2 proteins are degraded via autophagy, which is under control of Tor2, a homolog of human mTOR. It appears that failure in the two processes, downregulation of the glucose/cAMP signaling pathway and induction of autophagy, allows abnormal induction of Tf2s upon nitrogen starvation in Deltatsc2 and rhb1-DA4 cells. PMID- 30301782 TI - The AAA ATPase Afg1 preserves mitochondrial fidelity and cellular health by maintaining mitochondrial matrix proteostasis. AB - Mitochondrial functions are critical for cellular physiology; therefore, several conserved mechanisms are in place to maintain the functional integrity of mitochondria. However, many of the molecular details and components involved in ensuring mitochondrial fidelity remain obscure. Here, we identify a novel role for the conserved mitochondrial AAA ATPase Afg1 in mediating mitochondrial protein homeostasis during aging and in response to various cellular challenges. Saccharomyces cerevisiae cells lacking functional Afg1 are hypersensitive to oxidative insults, unable to tolerate protein misfolding in the matrix compartment and exhibit progressive mitochondrial failure as they age. Loss of the Afg1 ortholog LACE-1 in Caenorhabditis elegans is associated with reduced lifespan, impeded oxidative stress tolerance, impaired mitochondrial proteostasis in the motor neuron circuitry and altered behavioral plasticity. Our results indicate that Afg1 is a novel protein quality control factor, which plays an important evolutionarily conserved role in mitochondrial surveillance, and cellular and organismal health.

PMID- 30301784 TI - Mitochondrial ultrastructural adaptations in fast muscles of mice lacking IL15RA. AB - The pro-inflammatory cytokine interleukin-15 (IL15) and its receptor alpha (IL15RA) participate in the regulation of musculoskeletal function and metabolism. Deletion of the Il15ra gene in mice increases spontaneous activity, improves fatigue resistance in the glycolytic extensor digitorum longus (EDL) and protects from diet-induced obesity. In humans, IL15RA single-nucleotide polymorphisms (SNPs) have been linked to muscle strength, metabolism and performance in elite endurance athletes. Taken together, these features suggest a possible role for IL15RA in muscle mitochondrial structure and function. Here, we have investigated the consequences of loss of IL15RA on skeletal muscle fiber type properties and mitochondrial ultrastructure. Immunostaining of the EDL for myosin heavy chain (MyHC) isoforms revealed no significant changes in fiber type. Electron microscopy (EM) analysis of the EDL indicated an overall higher mitochondria content, and increased cristae density in subsarcolemmal and A-band mitochondrial subpopulations. The higher cristae density in Il15ra -/- mitochondria was associated with higher OPA1 and cardiolipin levels. Overall, these data extend our understanding of the role of IL15RA signaling in muscle oxidative metabolism and adaptation to exercise. PMID- 30301787 TI - Preassembled GPCR signaling complexes mediate distinct cellular responses to ultralow ligand concentrations. AB - G protein-coupled receptors (GPCRs) are the largest class of cell surface signaling proteins, participate in nearly all physiological processes, and are the targets of 30% of marketed drugs. Typically, nanomolar to micromolar concentrations of ligand are used to activate GPCRs in experimental systems. We detected GPCR responses to a wide range of ligand concentrations, from attomolar to millimolar, by measuring GPCR-stimulated production of cyclic adenosine monophosphate (cAMP) with high spatial and temporal resolution. Mathematical modeling showed that femtomolar concentrations of ligand activated, on average, 40% of the cells in a population provided that a cell was activated by one to two binding events. Furthermore, activation of the endogenous beta2-adrenergic receptor (beta2AR) and muscarinic acetylcholine M3 receptor (M3R) by femtomolar concentrations of ligand in cell lines and human cardiac fibroblasts caused sustained increases in nuclear translocation of extracellular signal-regulated kinase (ERK) and cytosolic protein kinase C (PKC) activity, respectively. These responses were spatially and temporally distinct from those that occurred in response to higher concentrations of ligand and resulted in a distinct cellular proteomic profile. This highly sensitive signaling depended on the GPCRs forming preassembled, higher-order signaling complexes at the plasma membrane. Recognizing that GPCRs respond to ultralow concentrations of neurotransmitters and hormones challenges established paradigms of drug action and provides a previously unappreciated aspect of GPCR activation that is quite distinct from that typically observed with higher ligand concentrations. PMID- 30301786 TI - The protein kinase p38alpha destabilizes p63 to limit epidermal stem cell frequency and tumorigenic potential. AB - The molecular circuitry directing tissue development and homeostasis is hardwired by genetic programs but may also be subject to fine-tuning or major modification by environmental conditions. It remains unclear whether such malleability is at work-particularly in tissues directly in contact with the environment-and contributes to their optimal maintenance and resilience. The protein kinase p38alpha is activated by physiological cues that signal tissue damage and neoplastic transformation. Here, we found that p38alpha phosphorylated and thereby destabilized p63, a transcription factor essential for epidermal development. Through this regulatory mechanism, p38alpha limited the frequency of keratinocytes with stem cell properties and tumorigenic potential. Correspondingly, epidermal loss of p38alpha expression or activity promoted or correlated with carcinogenesis in mouse and human skin, respectively. Genetic mouse models revealed a tumorigenic mechanism from p38alpha loss through p63 mediated suppression of the matrix metalloprotease MMP13. These findings illustrate a previously uncharacterized epidermal tumor-suppressive mechanism in which stress-activated signaling induces the contraction of stem cell-like keratinocyte pools. PMID- 30301789 TI - Arid5a makes the IL-17A/F-responsive pathway less arid. AB - The cytokine interleukin-17A/F (IL-17A/F) not only protects the skin and mucosae against Candida albicans infection in mice and humans but also promotes autoimmunity and autoinflammation in mice. In this issue of Science Signaling, Amatya et al report that the RNA binding protein Arid5a promotes responses to IL 17A/F through multiple mechanisms. PMID- 30301788 TI - IL-17 integrates multiple self-reinforcing, feed-forward mechanisms through the RNA binding protein Arid5a. AB - Interleukin-17A (IL-17A) not only stimulates immunity to fungal pathogens but also contributes to autoimmune pathology. IL-17 is only a modest activator of transcription in experimental tissue culture settings. However, IL-17 controls posttranscriptional events that enhance the expression of target mRNAs. Here, we showed that the RNA binding protein (RBP) Arid5a (AT-rich interactive domain containing protein 5a) integrated multiple IL-17-driven signaling pathways through posttranscriptional control of mRNA. IL-17 induced expression of Arid5a, which was recruited to the adaptor TRAF2. Arid5a stabilized IL-17-induced cytokine transcripts by binding to their 3' untranslated regions and also counteracted mRNA degradation mediated by the endoribonuclease MCPIP1 (Regnase 1). Arid5a inducibly associated with the eukaryotic translation initiation complex and facilitated the translation of the transcription factors (TFs) IkappaBzeta (Nfkbiz ) and C/EBPbeta (Cebpb). These TFs in turn transactivated IL 17-dependent promoters. Together, these data indicated that Arid5a orchestrates a feed-forward amplification loop, which promoted IL-17 signaling by controlling mRNA stability and translation. PMID- 30301790 TI - Neratinib is effective in breast tumors bearing both amplification and mutation of ERBB2 (HER2). AB - Mutations in ERBB2, the gene encoding epidermal growth factor receptor (EGFR) family member HER2, are common in and drive the growth of "HER2-negative" (not ERBB2 amplified) tumors but are rare in "HER2-positive" (ERBB2 amplified) breast cancer. We analyzed DNA-sequencing data from HER2-positive patients and used cell lines and a patient-derived xenograft model to test the consequence of HER2 mutations on the efficacy of anti-HER2 agents such as trastuzumab, lapatinib, and neratinib, an irreversible pan-EGFR inhibitor. HER2 mutations were present in ~7% of HER2-positive tumors, all of which were metastatic but not all were previously treated. Compared to HER2 amplification alone, in both patients and cultured cell lines, the co-occurrence of HER2 mutation and amplification was associated with poor response to trastuzumab and lapatinib, the standard-of-care anti-HER2 agents. In mice, xenografts established from a patient whose HER2-positive tumor acquired a D769Y mutation in HER2 after progression on trastuzumab-based therapy were resistant to trastuzumab or lapatinib but were sensitive to neratinib. Clinical data revealed that six heavily pretreated patients with tumors bearing coincident HER2 amplification and mutation subsequently exhibited a statistically significant response to neratinib monotherapy. Thus, these findings indicate that coincident HER2 mutation reduces the efficacy of therapies commonly used to treat HER2-positive breast cancer, particularly in metastatic and previously HER2 inhibitor-treated patients, as well as potentially in patients scheduled for first-line treatment. Therefore, we propose that clinical studies testing the efficacy of neratinib are warranted selectively in breast cancer patients whose tumors carry both amplification and mutation of ERBB2/HER2. PMID- 30301791 TI - Identification of SLAC1 anion channel residues required for CO2/bicarbonate sensing and regulation of stomatal movements. AB - Increases in CO2 concentration in plant leaves due to respiration in the dark and the continuing atmospheric [CO2] rise cause closing of stomatal pores, thus affecting plant-water relations globally. However, the underlying CO2/bicarbonate (CO2/HCO3 -) sensing mechanisms remain unknown. [CO2] elevation in leaves triggers stomatal closure by anion efflux mediated via the SLAC1 anion channel localized in the plasma membrane of guard cells. Previous reconstitution analysis has suggested that intracellular bicarbonate ions might directly up-regulate SLAC1 channel activity. However, whether such a CO2/HCO3 - regulation of SLAC1 is relevant for CO2 control of stomatal movements in planta remains unknown. Here, we computationally probe for candidate bicarbonate-interacting sites within the SLAC1 anion channel via long-timescale Gaussian accelerated molecular dynamics (GaMD) simulations. Mutations of two putative bicarbonate-interacting residues, R256 and R321, impaired the enhancement of the SLAC1 anion channel activity by CO2/HCO3 - in Xenopus oocytes. Mutations of the neighboring charged amino acid K255 and residue R432 and the predicted gate residue F450 did not affect HCO3 - regulation of SLAC1. Notably, gas-exchange experiments with slac1-transformed plants expressing mutated SLAC1 proteins revealed that the SLAC1 residue R256 is required for CO2 regulation of stomatal movements in planta, but not for abscisic acid (ABA)-induced stomatal closing. Patch clamp analyses of guard cells show that activation of S-type anion channels by CO2/HCO3 -, but not by ABA, was impaired, indicating the relevance of R256 for CO2 signal transduction. Together, these analyses suggest that the SLAC1 anion channel is one of the physiologically relevant CO2/HCO3 - sensors in guard cells. PMID- 30301793 TI - Metastatic growth instructed by neutrophil-derived transferrin. AB - The tumor-promoting functions of neutrophils have been mainly attributed to induction of tumor angiogenesis or suppression of anticancer immunity. However, a direct impact of neutrophils on tumor cell growth and metastasis remains largely uncharacterized. Here, we coupled a proteomic approach with a functional screen to interrogate the secretome of tumor-associated neutrophils. Surprisingly, the iron-transporting protein transferrin was identified as the major mitogen for tumor cells secreted by neutrophils. Depletion of neutrophils inhibited lung metastasis and transferrin production in the metastatic microenvironment. Deletion of transferrin receptor suppressed growth of lung-colonizing tumor cells. Also, media conditioned by neutrophils isolated from metastatic breast cancer patients stimulated growth of human breast cancer cells, an effect that was largely abolished by transferrin immunodepletion. We identified GM-CSF, which is produced primarily by tumor cells, as a selective inducer of de novo transferrin synthesis in neutrophils through the Jak/Stat5beta pathway. GM-CSF neutralization or inhibition of Jak kinases curtailed neutrophil transferrin expression in vitro and in vivo as well as cancer metastasis. Thus, transferrin provides a mechanistic link between neutrophils and metastatic growth owing to the ability of tumor-infiltrating neutrophils to locally deliver this growth promoting protein in response to GM-CSF stimulation. Our study identifies neutrophil-derived transferrin as a key regulator of metastatic tumor cell growth and a therapeutic target for antimetastatic treatment. PMID- 30301792 TI - Protein shape modulates crowding effects. AB - Protein-protein interactions are usually studied in dilute buffered solutions with macromolecule concentrations of <10 g/L. In cells, however, the macromolecule concentration can exceed 300 g/L, resulting in nonspecific interactions between macromolecules. These interactions can be divided into hard core steric repulsions and "soft" chemical interactions. Here, we test a hypothesis from scaled particle theory; the influence of hard-core repulsions on a protein dimer depends on its shape. We tested the idea using a side-by-side dumbbell-shaped dimer and a domain-swapped ellipsoidal dimer. Both dimers are variants of the B1 domain of protein G and differ by only three residues. The results from the relatively inert synthetic polymer crowding molecules, Ficoll and PEG, support the hypothesis, indicating that the domain-swapped dimer is stabilized by hard-core repulsions while the side-by-side dimer shows little to no stabilization. We also show that protein cosolutes, which interact primarily through nonspecific chemical interactions, have the same small effect on both dimers. Our results suggest that the shape of the protein dimer determines the influence of hard-core repulsions, providing cells with a mechanism for regulating protein-protein interactions. PMID- 30301794 TI - Machine learning determination of atomic dynamics at grain boundaries. AB - In polycrystalline materials, grain boundaries are sites of enhanced atomic motion, but the complexity of the atomic structures within a grain boundary network makes it difficult to link the structure and atomic dynamics. Here, we use a machine learning technique to establish a connection between local structure and dynamics of these materials. Following previous work on bulk glassy materials, we define a purely structural quantity (softness) that captures the propensity of an atom to rearrange. This approach correctly identifies crystalline regions, stacking faults, and twin boundaries as having low likelihood of atomic rearrangements while finding a large variability within high energy grain boundaries. As has been found in glasses, the probability that atoms of a given softness will rearrange is nearly Arrhenius. This indicates a well defined energy barrier as well as a well-defined prefactor for the Arrhenius form for atoms of a given softness. The decrease in the prefactor for low-softness atoms indicates that variations in entropy exhibit a dominant influence on the atomic dynamics in grain boundaries. PMID- 30301796 TI - A potential solution for eliminating hypoxia as a cause for radioresistance. PMID- 30301795 TI - Characterizing posttranslational modifications in prokaryotic metabolism using a multiscale workflow. AB - Understanding the complex interactions of protein posttranslational modifications (PTMs) represents a major challenge in metabolic engineering, synthetic biology, and the biomedical sciences. Here, we present a workflow that integrates multiplex automated genome editing (MAGE), genome-scale metabolic modeling, and atomistic molecular dynamics to study the effects of PTMs on metabolic enzymes and microbial fitness. This workflow incorporates complementary approaches across scientific disciplines; provides molecular insight into how PTMs influence cellular fitness during nutrient shifts; and demonstrates how mechanistic details of PTMs can be explored at different biological scales. As a proof of concept, we present a global analysis of PTMs on enzymes in the metabolic network of Escherichia coli Based on our workflow results, we conduct a more detailed, mechanistic analysis of the PTMs in three proteins: enolase, serine hydroxymethyltransferase, and transaldolase. Application of this workflow identified the roles of specific PTMs in observed experimental phenomena and demonstrated how individual PTMs regulate enzymes, pathways, and, ultimately, cell phenotypes. PMID- 30301797 TI - Why large icosahedral viruses need scaffolding proteins. AB - While small single-stranded viral shells encapsidate their genome spontaneously, many large viruses, such as the herpes simplex virus or infectious bursal disease virus (IBDV), typically require a template, consisting of either scaffolding proteins or an inner core. Despite the proliferation of large viruses in nature, the mechanisms by which hundreds or thousands of proteins assemble to form structures with icosahedral order (IO) is completely unknown. Using continuum elasticity theory, we study the growth of large viral shells (capsids) and show that a nonspecific template not only selects the radius of the capsid, but also leads to the error-free assembly of protein subunits into capsids with universal IO. We prove that as a spherical cap grows, there is a deep potential well at the locations of disclinations that later in the assembly process will become the vertices of an icosahedron. Furthermore, we introduce a minimal model and simulate the assembly of a viral shell around a template under nonequilibrium conditions and find a perfect match between the results of continuum elasticity theory and the numerical simulations. Besides explaining available experimental results, we provide a number of predictions. Implications for other problems in spherical crystals are also discussed. PMID- 30301798 TI - Nonproteinogenic deep mutational scanning of linear and cyclic peptides. AB - High-resolution structure-activity analysis of polypeptides requires amino acid structures that are not present in the universal genetic code. Examination of peptide and protein interactions with this resolution has been limited by the need to individually synthesize and test peptides containing nonproteinogenic amino acids. We describe a method to scan entire peptide sequences with multiple nonproteinogenic amino acids and, in parallel, determine the thermodynamics of binding to a partner protein. By coupling genetic code reprogramming to deep mutational scanning, any number of amino acids can be exhaustively substituted into peptides, and single experiments can return all free energy changes of binding. We validate this approach by scanning two model protein-binding peptides with 21 diverse nonproteinogenic amino acids. Dense structure-activity maps were produced at the resolution of single aliphatic atom insertions and deletions. This permits rapid interrogation of interaction interfaces, as well as optimization of affinity, fine-tuning of physical properties, and systematic assessment of nonproteinogenic amino acids in binding and folding. PMID- 30301799 TI - Human leukemia mutations corrupt but do not abrogate GATA-2 function. AB - By inducing the generation and function of hematopoietic stem and progenitor cells, the master regulator of hematopoiesis GATA-2 controls the production of all blood cell types. Heterozygous GATA2 mutations cause immunodeficiency, myelodysplastic syndrome, and acute myeloid leukemia. GATA2 disease mutations commonly disrupt amino acid residues that mediate DNA binding or cis-elements within a vital GATA2 intronic enhancer, suggesting a haploinsufficiency mechanism of pathogenesis. Mutations also occur in GATA2 coding regions distinct from the DNA-binding carboxyl-terminal zinc finger (C-finger), including the amino terminal zinc finger (N-finger), and N-finger function is not established. Whether distinct mutations differentially impact GATA-2 mechanisms is unknown. Here, we demonstrate that N-finger mutations decreased GATA-2 chromatin occupancy and attenuated target gene regulation. We developed a genetic complementation assay to quantify GATA-2 function in myeloid progenitor cells from Gata2 -77 enhancer-mutant mice. GATA-2 complementation increased erythroid and myeloid differentiation. While GATA-2 disease mutants were not competent to induce erythroid differentiation of Lin-Kit+ myeloid progenitors, unexpectedly, they promoted myeloid differentiation and proliferation. As the myelopoiesis-promoting activity of GATA-2 mutants exceeded that of GATA-2, GATA2 disease mutations are not strictly inhibitory. Thus, we propose that the haploinsufficiency paradigm does not fully explain GATA-2-linked pathogenesis, and an amalgamation of qualitative and quantitative defects instigated by GATA2 mutations underlies the complex phenotypes of GATA-2-dependent pathologies. PMID- 30301800 TI - C-type lectin receptor LSECtin-mediated apoptotic cell clearance by macrophages directs intestinal repair in experimental colitis. AB - Epithelial barrier disruption is a major cause of inflammatory bowel disease (IBD); however, the cellular and molecular regulation of intestinal epithelial homeostasis remains largely undefined. Here, we show that the C-type lectin receptor LSECtin (Clec4g) on macrophages is required for protection against dextran sulfate sodium-induced colitis. Mechanistically, LSECtin promotes apoptotic cell clearance by macrophages and induces the production of antiinflammatory/tissue repair factors in an engulfment-dependent manner, which in turn stimulates epithelial cell proliferation. Deletion of LSECtin results in defective engulfment by colon macrophages, leading to aberrant proresolving factor production and impaired intestinal epithelium repair. Collectively, our findings suggest that LSECtin-dependent corpse clearance by macrophages can direct intestinal regeneration and maintenance of the mucosal barrier after injury. PMID- 30301802 TI - MmpL8MAB controls Mycobacterium abscessus virulence and production of a previously unknown glycolipid family. AB - Mycobacterium abscessus is a peculiar rapid-growing Mycobacterium (RGM) capable of surviving within eukaryotic cells thanks to an arsenal of virulence genes also found in slow-growing mycobacteria (SGM), such as Mycobacterium tuberculosis A screen based on the intracellular survival in amoebae and macrophages (MPhi) of an M. abscessus transposon mutant library revealed the important role of MAB_0855, a yet uncharacterized Mycobacterial membrane protein Large (MmpL). Large-scale comparisons with SGM and RGM genomes uncovered MmpL12 proteins as putative orthologs of MAB_0855 and a locus-scale synteny between the MAB_0855 and Mycobacterium chelonae mmpL8 loci. A KO mutant of the MAB_0855 gene, designated herein as mmpL8 MAB , had impaired adhesion to MPhi and displayed a decreased intracellular viability. Despite retaining the ability to block phagosomal acidification, like the WT strain, the mmpL8 MAB mutant was delayed in damaging the phagosomal membrane and in making contact with the cytosol. Virulence attenuation of the mutant was confirmed in vivo by impaired zebrafish killing and a diminished propensity to induce granuloma formation. The previously shown role of MmpL in lipid transport prompted us to investigate the potential lipid substrates of MmpL8MAB Systematic lipid analysis revealed that MmpL8MAB was required for the proper expression of a glycolipid entity, a glycosyl diacylated nonadecyl diol (GDND) alcohol comprising different combinations of oleic and stearic acids. This study shows the importance of MmpL8MAB in modifying interactions between the bacteria and phagocytic cells and in the production of a previously unknown glycolipid family. PMID- 30301801 TI - Activity-dependent bulk endocytosis proteome reveals a key presynaptic role for the monomeric GTPase Rab11. AB - Activity-dependent bulk endocytosis (ADBE) is the dominant mode of synaptic vesicle endocytosis during high-frequency stimulation, suggesting it should play key roles in neurotransmission during periods of intense neuronal activity. However, efforts in elucidating the physiological role of ADBE have been hampered by the lack of identified molecules which are unique to this endocytosis mode. To address this, we performed proteomic analysis on purified bulk endosomes, which are a key organelle in ADBE. Bulk endosomes were enriched via two independent approaches, a classical subcellular fractionation method and isolation via magnetic nanoparticles. There was a 77% overlap in proteins identified via the two protocols, and these molecules formed the ADBE core proteome. Bioinformatic analysis revealed a strong enrichment in cell adhesion and cytoskeletal and signaling molecules, in addition to expected synaptic and trafficking proteins. Network analysis identified Rab GTPases as a central hub within the ADBE proteome. Subsequent investigation of a subset of these Rabs revealed that Rab11 both facilitated ADBE and accelerated clathrin-mediated endocytosis. These findings suggest that the ADBE proteome will provide a rich resource for the future study of presynaptic function, and identify Rab11 as a regulator of presynaptic function. PMID- 30301804 TI - Translating biased signaling in the ghrelin receptor system into differential in vivo functions. AB - Biased signaling has been suggested as a means of selectively modulating a limited fraction of the signaling pathways for G-protein-coupled receptor family members. Hence, biased ligands may allow modulation of only the desired physiological functions and not elicit undesired effects associated with pharmacological treatments. The ghrelin receptor is a highly sought antiobesity target, since the gut hormone ghrelin in humans has been shown to increase both food intake and fat accumulation. However, it also modulates mood, behavior, growth hormone secretion, and gastric motility. Thus, blocking all pathways of this receptor may give rise to potential side effects. In the present study, we describe a highly promiscuous signaling capacity for the ghrelin receptor. We tested selected ligands for their ability to regulate the various pathways engaged by the receptor. Among those, a biased ligand, YIL781, was found to activate the Galphaq/11 and Galpha12 pathways selectively without affecting the engagement of beta-arrestin or other G proteins. YIL781 was further characterized for its in vivo physiological functions. In combination with the use of mice in which Galphaq/11 was selectively deleted in the appetite-regulating AgRP neurons, this biased ligand allowed us to demonstrate that selective blockade of Galphaq/11, without antagonism at beta-arrestin or other G-protein coupling is sufficient to decrease food intake. PMID- 30301803 TI - Meiosis-specific recombinase Dmc1 is a potent inhibitor of the Srs2 antirecombinase. AB - Cross-over recombination products are a hallmark of meiosis because they are necessary for accurate chromosome segregation and they also allow for increased genetic diversity during sexual reproduction. However, cross-overs can also cause gross chromosomal rearrangements and are therefore normally down-regulated during mitotic growth. The mechanisms that enhance cross-over product formation upon entry into meiosis remain poorly understood. In Saccharomyces cerevisiae, the Superfamily 1 (Sf1) helicase Srs2, which is an ATP hydrolysis-dependent motor protein that actively dismantles recombination intermediates, promotes synthesis dependent strand annealing, the result of which is a reduction in cross-over recombination products. Here, we show that the meiosis-specific recombinase Dmc1 is a potent inhibitor of Srs2. Biochemical and single-molecule assays demonstrate that Dmc1 acts by inhibiting Srs2 ATP hydrolysis activity, which prevents the motor protein from undergoing ATP hydrolysis-dependent translocation on Dmc1 bound recombination intermediates. We propose a model in which Dmc1 helps contribute to cross-over formation during meiosis by antagonizing the antirecombinase activity of Srs2. PMID- 30301805 TI - Chronic social stress-induced hyperglycemia in mice couples individual stress susceptibility to impaired spatial memory. AB - Stringent glucose demands render the brain susceptible to disturbances in the supply of this main source of energy, and chronic stress may constitute such a disruption. However, whether stress-associated cognitive impairments may arise from disturbed glucose regulation remains unclear. Here we show that chronic social defeat (CSD) stress in adult male mice induces hyperglycemia and directly affects spatial memory performance. Stressed mice developed hyperglycemia and impaired glucose metabolism peripherally as well as in the brain (demonstrated by PET and induced metabolic bioluminescence imaging), which was accompanied by hippocampus-related spatial memory impairments. Importantly, the cognitive and metabolic phenotype pertained to a subset of stressed mice and could be linked to early hyperglycemia 2 days post-CSD. Based on this criterion, ~40% of the stressed mice had a high-glucose (glucose >150 mg/dL), stress-susceptible phenotype. The relevance of this biomarker emerges from the effects of the glucose-lowering sodium glucose cotransporter 2 inhibitor empagliflozin, because upon dietary treatment, mice identified as having high glucose demonstrated restored spatial memory and normalized glucose metabolism. Conversely, reducing glucose levels by empagliflozin in mice that did not display stress-induced hyperglycemia (resilient mice) impaired their default-intact spatial memory performance. We conclude that hyperglycemia developing early after chronic stress threatens long-term glucose homeostasis and causes spatial memory dysfunction. Our findings may explain the comorbidity between stress-related and metabolic disorders, such as depression and diabetes, and suggest that cognitive impairments in both types of disorders could originate from excessive cerebral glucose accumulation. PMID- 30301807 TI - Redox-dependent niche differentiation provides evidence for multiple bacterial sources of glycerol tetraether lipids in lakes. AB - Terrestrial paleoclimate archives such as lake sediments are essential for our understanding of the continental climate system and for the modeling of future climate scenarios. However, quantitative proxies for the determination of paleotemperatures are sparse. The relative abundances of certain bacterial lipids, i.e., branched glycerol dialkyl glycerol tetraethers (brGDGTs), respond to changes in environmental temperature, and thus have great potential for climate reconstruction. Their application to lake deposits, however, is hampered by the lack of fundamental knowledge on the ecology of brGDGT-producing microbes in lakes. Here, we show that brGDGTs are synthesized by multiple groups of bacteria thriving under contrasting redox regimes in a deep meromictic Swiss lake (Lake Lugano). This niche partitioning is evidenced by highly distinct brGDGT inventories in oxic vs. anoxic water masses, and corresponding vertical patterns in bacterial 16S rRNA gene abundances, implying that sedimentary brGDGT records are affected by temperature-independent changes in the community composition of their microbial producers. Furthermore, the stable carbon isotope composition (delta13C) of brGDGTs in Lake Lugano and 34 other (peri-)Alpine lakes attests to the widespread heterotrophic incorporation of 13C-depleted, methane-derived biomass at the redox transition zone of mesotrophic to eutrophic lake systems. The brGDGTs produced under such hypoxic/methanotrophic conditions reflect near bottom water temperatures, and are characterized by comparatively low delta13C values. Depending on climate zone and water depth, lake sediment archives predominated by deeper water/low-13C brGDGTs may provide more reliable records of climate variability than those where brGDGTs derive from terrestrial and/or aquatic sources with distinct temperature imprints. PMID- 30301806 TI - Molecular mechanism of activation of the immunoregulatory amidase NAAA. AB - Palmitoylethanolamide is a bioactive lipid that strongly alleviates pain and inflammation in animal models and in humans. Its signaling activity is terminated through degradation by N-acylethanolamine acid amidase (NAAA), a cysteine hydrolase expressed at high levels in immune cells. Pharmacological inhibitors of NAAA activity exert profound analgesic and antiinflammatory effects in rodent models, pointing to this protein as a potential target for therapeutic drug discovery. To facilitate these efforts and to better understand the molecular mechanism of action of NAAA, we determined crystal structures of this enzyme in various activation states and in complex with several ligands, including both a covalent and a reversible inhibitor. Self-proteolysis exposes the otherwise buried active site of NAAA to allow catalysis. Formation of a stable substrate- or inhibitor-binding site appears to be conformationally coupled to the interaction of a pair of hydrophobic helices in the enzyme with lipid membranes, resulting in the creation of a linear hydrophobic cavity near the active site that accommodates the ligand's acyl chain. PMID- 30301808 TI - Human mitochondrial degradosome prevents harmful mitochondrial R loops and mitochondrial genome instability. AB - R loops are nucleic acid structures comprising an DNA-RNA hybrid and a displaced single-stranded DNA. These structures may occur transiently during transcription, playing essential biological functions. However, persistent R loops may become pathological as they are important drivers of genome instability and have been associated with human diseases. The mitochondrial degradosome is a functionally conserved complex from bacteria to human mitochondria. It is composed of the ATP dependent RNA and DNA helicase SUV3 and the PNPase ribonuclease, playing a central role in mitochondrial RNA surveillance and degradation. Here we describe a new role for the mitochondrial degradosome in preventing the accumulation of pathological R loops in the mitochondrial DNA, in addition to preventing dsRNA accumulation. Our data indicate that, similar to the molecular mechanisms acting in the nucleus, RNA surveillance mechanisms in the mitochondria are crucial to maintain its genome integrity by counteracting pathological R-loop accumulation. PMID- 30301810 TI - Highly disordered histone H1-DNA model complexes and their condensates. AB - Disordered proteins play an essential role in a wide variety of biological processes, and are often posttranslationally modified. One such protein is histone H1; its highly disordered C-terminal tail (CH1) condenses internucleosomal linker DNA in chromatin in a way that is still poorly understood. Moreover, CH1 is phosphorylated in a cell cycle-dependent manner that correlates with changes in the chromatin condensation level. Here we present a model system that recapitulates key aspects of the in vivo process, and also allows a detailed structural and biophysical analysis of the stages before and after condensation. CH1 remains disordered in the DNA-bound state, despite its nanomolar affinity. Phase-separated droplets (coacervates) form, containing higher-order assemblies of CH1/DNA complexes. Phosphorylation at three serine residues, spaced along the length of the tail, has little effect on the local properties of the condensate. However, it dramatically alters higher-order structure in the coacervate and reduces partitioning to the coacervate phase. These observations show that disordered proteins can bind tightly to DNA without a disorder-to-order transition. Importantly, they also provide mechanistic insights into how higher-order structures can be exquisitely sensitive to perturbation by posttranslational modifications, thus broadening the repertoire of mechanisms that might regulate chromatin and other macromolecular assemblies. PMID- 30301809 TI - mTOR inhibitors lower an intrinsic barrier to virus infection mediated by IFITM3. AB - Rapamycin and its derivatives are specific inhibitors of mammalian target of rapamycin (mTOR) kinase and, as a result, are well-established immunosuppressants and antitumorigenic agents. Additionally, this class of drug promotes gene delivery by facilitating lentiviral vector entry into cells, revealing its potential to improve gene therapy efforts. However, the precise mechanism was unknown. Here, we report that mTOR inhibitor treatment results in down-regulation of the IFN-induced transmembrane (IFITM) proteins. IFITM proteins, especially IFITM3, are potent inhibitors of virus-cell fusion and are broadly active against a range of pathogenic viruses. We found that the effect of rapamycin treatment on lentiviral transduction is diminished upon IFITM silencing or knockout in primary and transformed cells, and the extent of transduction enhancement depends on basal expression of IFITM proteins, with a major contribution from IFITM3. The effect of rapamycin treatment on IFITM3 manifests at the level of protein, but not mRNA, and is selective, as many other endosome-associated transmembrane proteins are unaffected. Rapamycin-mediated degradation of IFITM3 requires endosomal trafficking, ubiquitination, endosomal sorting complex required for transport (ESCRT) machinery, and lysosomal acidification. Since IFITM proteins exhibit broad antiviral activity, we show that mTOR inhibition also promotes infection by another IFITM-sensitive virus, Influenza A virus, but not infection by Sendai virus, which is IFITM-resistant. Our results identify the molecular basis by which mTOR inhibitors enhance virus entry into cells and reveal a previously unrecognized immunosuppressive feature of these clinically important drugs. In addition, this study uncovers a functional convergence between the mTOR pathway and IFITM proteins at endolysosomal membranes. PMID- 30301813 TI - Reproductive outsourcing: an empirical ethics account of cross-border reproductive care in Canada. AB - Cross-border reproductive care (CBRC) can be defined as the movement from one jurisdiction to another for medically assisted reproduction (MAR). CBRC raises many ethical concerns that have been addressed extensively. However, the conclusions are still based on scarce evidence even considering the global scale of CBRC. Empirical ethics appears as a way to foster this ethical reflection on CBRC while attuning it with the experiences of its main actors. To better understand the 'in and out' situation of CBRC in Canada, we conducted an ethnographic study taking a 'critically applied ethics' approach. This article presents a part of the findings of this research, obtained by data triangulation from qualitative analysis of pertinent literature, participant observation in two Canadian fertility clinics and 40 semidirected interviews. Based on participants' perceptions, four themes emerged: (1) inconsistencies of the Canadian legal framework; (2) autonomy and the necessity to resort to CBRC; (3) safety and the management of CBRC individual risks; and (4) justice and solidarity. The interaction between these four themes highlights the problematic of 'reproductive outsourcing' that characterised the Canadian situation, a system where the controversial aspects of MAR are knowingly pushed outside the borders. PMID- 30301811 TI - Combined inhibition of receptor tyrosine and p21-activated kinases as a therapeutic strategy in childhood ALL. AB - Receptor tyrosine kinase (RTK)-dependent signaling has been implicated in the pathogenesis of acute lymphoblastic leukemia (ALL) of childhood. However, the RTK dependent signaling state and its interpretation with regard to biological behavior are often elusive. To decipher signaling circuits that link RTK activity with biological output in vivo, we established patient-derived xenograft ALL (PDX ALL) models with dependencies on fms-like tyrosine kinase 3 (FLT3) and platelet derived growth factor receptor beta (PDGFRB), which were interrogated by phosphoproteomics using iTRAQ mass spectrometry. Signaling circuits were determined by receptor type and cellular context with few generic features, among which we identified group I p21-activated kinases (PAKs) as potential therapeutic targets. Growth factor stimulation markedly increased catalytic activities of PAK1 and PAK2. RNA interference (RNAi)-mediated or pharmacological inhibition of PAKs using allosteric or adenosine triphosphate (ATP)-competitive compounds attenuated cell growth and increased apoptosis in vitro. Notably, PAK1- or PAK2 directed RNAi enhanced the antiproliferative effects of the type III RTK and protein kinase C inhibitor midostaurin. Treatment of FLT3- or PDGFRB-dependent ALLs with ATP-competitive PAK inhibitors markedly decreased catalytic activities of both PAK isoforms. In FLT3-driven ALL, this effect was augmented by coadministration of midostaurin resulting in synergistic effects on growth inhibition and apoptosis. Finally, combined treatment of FLT3 D835H PDX-ALL with the ATP-competitive group I PAK inhibitor FRAX486 and midostaurin in vivo significantly prolonged leukemia progression-free survival compared with midostaurin monotherapy or control. Our study establishes PAKs as potential downstream targets in RTK-dependent ALL of childhood, the inhibition of which might help prevent the selection or acquisition of resistance mutations toward tyrosine kinase inhibitors. PMID- 30301812 TI - Accelerated, but not conventional, radiotherapy of murine B-cell lymphoma induces potent T cell-mediated remissions. AB - Conventional local tumor irradiation (LTI), delivered in small daily doses over several weeks, is used clinically as a palliative, rather than curative, treatment for chemotherapy-resistant diffuse large B-cell lymphoma (DLBCL) for patients who are ineligible for hematopoietic cell transplantation. Our goal was to test the hypothesis that accelerated, but not conventional, LTI would be more curative by inducing T cell-mediated durable remissions. We irradiated subcutaneous A20 and BL3750 lymphoma tumors in mice with a clinically relevant total radiation dose of 30 Gy LTI, delivered in 10 doses of 3 Gy over 4 days (accelerated irradiation) or as 10 doses of 3 Gy over 12 days (conventional irradiation). Compared with conventional LTI, accelerated LTI resulted in more complete and durable tumor remissions. The majority of these mice were resistant to rechallenge with lymphoma cells, demonstrating the induction of memory antitumor immunity. The increased efficacy of accelerated LTI correlated with higher levels of tumor cell necrosis vs apoptosis and expression of "immunogenic cell death" markers, including calreticulin, heat shock protein 70 (Hsp70), and Hsp90. Accelerated LTI-induced remissions were not seen in immunodeficient Rag-2 /- mice, CD8+ T-cell-depleted mice, or Batf-3 -/- mice lacking CD8alpha+ and CD103+ dendritic cells. Accelerated, but not conventional, LTI in immunocompetent hosts induced marked increases in tumor-infiltrating CD4+ and CD8+ T cells and MHCII+CD103+CD11c+ dendritic cells and corresponding reductions in exhausted PD 1+Eomes+CD8+ T cells and CD4+CD25+FOXP3+ regulatory T cells. These findings raise the possibility that accelerated LTI can provide effective immune control of human DLBCL. PMID- 30301814 TI - The rebirth of medical paternalism: An NHS Trust v Y. AB - Over the last quarter of a century, English medical law has taken an increasingly firm stand against medical paternalism. This is exemplified by cases such as Bolitho v City and Hackney Health Authority, Chester v Afshar, and Montgomery v Lanarkshire Health Board. In relation to decision-making on behalf of incapacitous adults, the actuating principle of the Mental Capacity Act 2005 is respect for patient autonomy. The only lawful acts in relation to an incapacitous person are acts which are in the best interests of that person. The 2005 Act requires a holistic assessment of best interests. Best interests are wider than 'medical best interests'. The 2018 judgment of the Supreme Court in An NHS Trust v Y (which concerned the question of whether a court needed to authorise the withdrawal of life-sustaining clinically administered nutrition/hydration (CANH) from patients in prolonged disorders of consciousness (PDOC)) risks reviving medical paternalism. The judgment, in its uncritical endorsement of guidelines from various medical organisations, may lend inappropriate authority to medical judgments of best interests and silence or render impotent non-medical contributions to the debate about best interests-so frustrating the 2005 Act. To minimise these dangers, a system of meditation should be instituted whenever it is proposed to withdraw (at least) life-sustaining CANH from (at least) patients with PDOC, and there needs to be a guarantee of access to the courts for families, carers and others who wish to challenge medical conclusions about withdrawal. This would entail proper public funding for such challenges. PMID- 30301815 TI - Sixty seconds on . . . Emma's Diary. PMID- 30301816 TI - Making MOC Quality Improvement Participation Meaningful. PMID- 30301817 TI - Pediatricians' Participation in Quality Improvement at the Time of Enrollment in MOC. AB - BACKGROUND AND OBJECTIVES: Although national bodies have proclaimed the importance of incorporating quality improvement (QI) into the daily fabric of clinical care, the actual proportion of practicing pediatricians who participate in QI activities on an annual basis is unknown. Correspondingly little is known about pediatrician motivations for, attitudes about, and support received for QI participation. METHODS: Pediatric diplomates enrolling in the American Board of Pediatrics' Maintenance of Certification program during calendar year 2016 were provided with the opportunity to complete a brief survey. A portion of the survey was focused on issues related to participation in QI programs. RESULTS: Survey responses were received from 8714 of the 11 890 diplomates who enrolled in Maintenance of Certification in 2016 (response rate: 73.3%). Overall, 86.6% of respondents reported participation in at least 1 QI project in the previous year. There was variation in previous-year participation in a QI project by practice affiliation categories, ranging from 79.9% for nonacademic generalists to 92.4% for academic specialists. The extrinsic requirement for QI to maintain board certification was the dominant motivator among all respondents (50.7%), followed by 2 intrinsic factors: identify gaps in practice and implement change (40.3%) and opportunity to collaborate with others (36.9%). CONCLUSIONS: Although the results are encouraging, despite almost 2 decades of national attention to the quality of health care and efforts to embed continual QI in health care delivery activities, ~1 in 5 nonacademic pediatricians and 1 in 10 academic pediatricians did not report participating in any QI activities in the previous year. PMID- 30301818 TI - Incidence of primary graft dysfunction after lung transplantation is altered by timing of allograft implantation. AB - The importance of circadian factors in managing patients is poorly understood. We present two retrospective cohort studies showing that lungs reperfused between 4 and 8 AM have a higher incidence (OR 1.12; 95% CI 1.03 to 1.21; p=0.01) of primary graft dysfunction (PGD) in the first 72 hours after transplantation. Cooling of the donor lung, occurring during organ preservation, shifts the donor circadian clock causing desynchrony with the recipient. The clock protein REV ERBalpha directly regulates PGD biomarkers explaining this circadian regulation while also allowing them to be manipulated with synthetic REV-ERB ligands. PMID- 30301819 TI - Gaps in the evidence for treatment decisions in cystic fibrosis: a systematic review. AB - INTRODUCTION: Cystic fibrosis (CF) is a multisystem disorder. Treatment is complex and evidence for treatment decisions may be absent. Characterising gaps in the research evidence will highlight treatment uncertainties and help prioritise research questions. We systematically identified the evidence gaps for treatment decisions in CF. METHODS: We searched for systematic reviews and guidelines on treatment interventions in CF. Two researchers identified eligible reviews with arbitration from a third. Using a structured framework, we extracted and characterised evidence gaps. RESULTS: There were 73 reviews and 21 guidelines that met our inclusion criteria. From these, we identified 148 evidence gaps across a range of treatment areas. We found 111 evidence gaps through systematic reviews and a further 37 from guidelines. The reason for an evidence gap could only be reliably characterised for systematic reviews. In most cases, there was more than one explanation-most commonly few or no trials (97/111 evidence gaps). Other important factors leading to evidence gaps were small sample size (49/111), inadequate duration of follow-up (38/111) or intervention (37/111) and factors relating to outcomes (35/111). Evidence gaps from both systematic reviews and guidelines fell into the following categories: Respiratory (91); Gastrointestinal (20); PhysiotherapyandExercise (16); Musculoskeletal (6); Endocrine (4); Basic defect of CF (8); Psychosocial (2); Ears, Nose and Throat (1). CONCLUSIONS: We have compiled an up-to-date list of treatment uncertainties in CF and the reasons for these uncertainties. These can be used as a resource to aid researchers and funders when planning future trials. PROSPERO REGISTRATION NUMBER: Pre-results; CRD42015030111. PMID- 30301820 TI - Coeliac disease in children. PMID- 30301821 TI - Angling-induced injuries have a negative impact on suction feeding performance and hydrodynamics in marine shiner perch, Cymatogaster aggregata. AB - Fishing is a popular and lucrative sport around the world and, in some cases, may contribute to declining fish stocks. To mediate this problem and maintain fish biomass in aquatic ecosystems, catch-and-release fishing, whereby a fish is caught and immediately released, has been implemented in many countries. It is unclear whether the injuries to the mouth that are caused by the hook have an impact on feeding performance of fishes. Using high-speed video and computational fluid dynamics (CFD), we asked whether injuries around the mouth caused by fishing hooks have a negative impact on suction feeding performance (measured as maximum prey velocity) of the commonly angled marine shiner perch (Cymatogaster aggregata). We hypothesized that fish with mouth injuries would exhibit decreased feeding performance compared with controls. Ten shiner perch were caught using scientific angling and 10 were caught using a seine net. Feeding events were then recorded at 500 frames per second using a high-speed camera. Compared with the control group, maximum prey velocity was significantly lower in the injured group (P<0.01). Maximum gape, time to peak gape, maximum jaw protrusion and predator prey distance were comparable between the control and injured groups, leading us to conclude that the injury-induced hole in the buccal cavity wall reduced the pressure gradient during mouth expansion, thereby reducing the velocity of water entering the fish's mouth. This was confirmed with our CFD modelling. Fishing injuries in nature are likely to depress feeding performance of fish after they have been released, although it is currently unclear whether this has a significant impact on survival.

PMID- 30301823 TI - Twenty years of research on attention-deficit/hyperactivity disorder (ADHD): looking back, looking forward. AB - In this clinical review we summarise what in our view have been some the most important advances in the past two decades, in terms of diagnostic definition, epidemiology, genetics and environmental causes, neuroimaging/cognition and treatment of attention-deficit/hyperactivity disorder (ADHD), including: (1) the most recent changes to the diagnostic criteria in the Diagnostic and Statistical Manual of Mental Disorders and International Classification of Diseases; (2) meta analytic evidence showing that, after accounting for diagnostic methods, the rates of ADHD are fairly consistent across Western countries; (3) the recent finding of the first genome-wide significant risk loci for ADHD; (4) the paradigm shift in the pathophysiological conceptualisation of ADHD from alterations in individual brain regions to a complex dysfunction in brain networks; (5) evidence supporting the short-term efficacy of ADHD pharmacological treatments, with a different profile of efficacy and tolerability in children/adolescents versus adults; (6) a series of meta-analyses showing that, while non-pharmacological treatment may not be effective to target ADHD core symptoms, some of them effectively address ADHD-related impairments (such as oppositional behaviours for parent training and working memory deficits for cognitive training). We also discuss key priorities for future research in each of these areas of investigation. Overall, while many research questions have been answered, many others need to be addressed. Strengthening multidisciplinary collaborations, relying on large data sets in the spirit of Open Science and supporting research in less advantaged countries will be key to face the challenges ahead. PMID- 30301824 TI - Inflammation and psychopathology in children following PICU admission: an exploratory study. AB - BACKGROUND: Survivors of critical illness in childhood commonly display subsequent psychiatric symptoms including emotional and behavioural difficulties, and manifestations of post-traumatic stress disorder (PTSD). Anomalies in inflammatory profiles are an established finding in these childhood psychiatric conditions. OBJECTIVE: This exploratory study aimed to investigate whether abnormal peripheral blood inflammatory markers measured during paediatric intensive care unit (PICU) admission were associated with psychiatric symptoms after discharge. METHODS: We performed a prospective observational cohort study on 71 children with septic illness, meningoencephalitis and other critical disorders admitted to two PICUs between 2007 and 2010. 3-6 months following discharge, subjects were assessed for global psychiatric risk (ie, presence of emotional and behavioural difficulties on the parental Strengths and Difficulties Questionnaire (SDQ)), and for PTSD risk using the child-rated Impact of Events Scale (IES-8). Inflammatory and related biological markers were transcribed from PICU admission notes (white cell count, lymphocytes, neutrophils, C reactive protein (CRP), platelets, fibrinogen and lactate). FINDINGS: Global psychiatric risk at follow-up was associated with abnormal lymphocyte count during admission (chi2=6.757, p=0.014, n=48). In children with sepsis, partial correlation analyses controlling for age and gender highlighted associations between (i) SDQ scores and low lymphocyte count (r=-0.712; p=0.009, n=14), and (ii) IES-8 score and high CRP levels (r=0.823; p=0.006, n=11). These associations remained after correction for multiple comparisons. CONCLUSION: These results support the hypothesis that acute inflammation may play a role in determining the development of psychopathology following PICU admission. CLINICAL IMPLICATIONS: If the findings are replicated, they may help to better highlight which children are at risk of post-PICU psychopathology and appropriately target follow-up. PMID- 30301826 TI - Near-Infrared Dye-Labeled Anti-Prostate Stem Cell Antigen Minibody Enables Real Time Fluorescence Imaging and Targeted Surgery in Translational Mouse Models. AB - Purpose: The inability to intraoperatively distinguish primary tumor, as well as lymphatic spread, increases the probability of positive surgical margins, tumor recurrence, and surgical toxicity. The goal of this study was to develop a tumor specific optical probe for real-time fluorescence-guided surgery.Experimental Design: A humanized antibody fragment against PSCA (A11 minibody, A11 Mb) was conjugated with a near-infrared fluorophore, IRDye800CW. The integrity and binding of the probe to PSCA were confirmed by gel electrophoresis, size exclusion chromatography, and flow cytometry, respectively. The ability of the probe to detect tumor-infiltrated lymph nodes and metastatic lesions was evaluated in 2 xenograft models, as well as in transgenic mice expressing human PSCA (hPSCA). An invasive intramuscular model was utilized to evaluate the efficacy of the A11 Mb-IRDye800CW-guided surgery.Results: A11 Mb was successfully conjugated with IRDye800CW and retained specific binding to PSCA. In vivo imaging showed maximal signal-to-background ratios at 48 hours. The A11 Mb-IRDye800CW specifically detected PSCA-positive primary tumors, tumor-infiltrated lymph nodes, and distant metastases with high contrast. Fluorescence guidance facilitated more complete tumor resection, reduced tumor recurrence, and improved overall survival, compared with conventional white light surgery. The probe successfully identified primary orthotopic tumors and metastatic lesions in hPSCA transgenic mice.Conclusions: Real-time fluorescence image-guided surgery with A11 Mb-IRDye800CW enabled detection of lymph node metastases and positive surgical margins, facilitated more complete tumor removal, and improved survival, compared with white light surgery. These results may be translatable into clinical practice to improve surgical and patient outcomes. Clin Cancer Res; 1-13. (c)2018 AACR. PMID- 30301825 TI - Intertumoral Heterogeneity of CD3+ and CD8+ T-Cell Densities in the Microenvironment of DNA Mismatch-Repair-Deficient Colon Cancers: Implications for Prognosis. AB - Background: Colorectal cancers with deficient DNA mismatch repair (dMMR) are presumed to uniformly have dense lymphocytic infiltration that underlies their favorable prognosis and is critical to their responsiveness to immunotherapy, as compared with MMR-proficient (pMMR) tumors. We examined T-cell densities and their potential heterogeneity in a large cohort of dMMR tumors.Experimental Design: CD3+ and CD8+ T-cell densities were quantified at the invasive margin (IM) and tumor core (CT) in 561 stage III colon cancers (dMMR, n = 278; pMMR, n = 283) from a phase III adjuvant trial (N0147). Their association with overall survival (OS) was determined using multivariable Cox analysis.Results: Although CD3+ and CD8+ T-cell densities in the tumor microenvironment were higher in dMMR versus pMMR tumors overall, intertumoral heterogeneity in densities between tumors was significantly higher by 30% to 88% among dMMR versus pMMR cancers (P < 0.0001 for all four T-cell subtypes [CD3+IM, CD3+CT, CD8+IM, CD8+CT]). A substantial proportion of dMMR tumors (26% to 35% depending on the T-cell subtype) exhibited T-cell densities as low as that in the bottom half of pMMR tumors. All four T-cell subtypes were prognostic in dMMR with CD3+IM being the most strongly prognostic. Low (vs. high) CD3+IM was independently associated with poorer OS among dMMR (HR, 4.76; 95% confidence interval, 1.43-15.87; P = 0.0019) and pMMR tumors (P = 0.0103).Conclusions: Tumor-infiltrating T-cell densities exhibited greater intertumoral heterogeneity among dMMR than pMMR colon cancers, with CD3+IM providing robust stratification of both dMMR and pMMR tumors for prognosis. Potentially, lower T-cell densities among dMMR tumors may contribute to immunotherapy resistance. Clin Cancer Res; 1-9. (c)2018 AACR. PMID- 30301827 TI - Transcription Factor Myeloid Zinc-Finger 1 Suppresses Human Gastric Carcinogenesis by Interacting with Metallothionein 2A. AB - PURPOSE: Metallothionein 2A (MT2A) suppresses the progression of human gastric cancer (GC) potentially through an "MT2A-NF-kappaB pathway" with unclear mechanisms. This study explored the role of a transcription factor, myeloid zinc finger 1 (MZF1), in MT2A-NF-kappaB pathway and its clinical significance in GC. EXPERIMENTAL DESIGN: MZF1 expression and function in GC were investigated in vitro and in vivo. The relationship between MZF1 and MT2A was determined by gain- and loss-of-function assays in GC cells and an immortalized gastric cell line GES 1. The prognostic value of MZF1 expression in association with MT2A was evaluated using immunohistochemistry in two cohorts. RESULTS: MZF1 was epigenetically silenced in human GC cell lines and primary tumors. Overexpression of MZF1 in GC cells suppressed cell proliferation and migration, as well as the growth of xenograft tumors in nude mice. Knocking-down of MZF1 transformed GES-1 cells into a malignant phenotype characterized by increased cell growth and migration. Mechanistically, MZF1 was upregulated in both GC and GES-1 cells by MT2A ectopically expressed or induced upon treatment with a garlic-derived compound, diallyl trisulfide (DATS). MZF1 associated with MT2A was co-localized in the nuclei of GES-1 cells to target the promoter of NFKB inhibitor alpha (NFKBIA). Clinically, MT2A and MZF1 were progressively downregulated in clinical specimens undergoing gastric malignant transformation. Downregulation of MT2A and MZF1 was significantly correlated with poorer patient prognosis. CONCLUSIONS: MT2A exerts its anti-GC effects by complexing with MZF1 to target NFKBIA. MT2A/MZF1 may serve as valuable prognostic markers and novel therapeutic targets for human GC. PMID- 30301828 TI - Telomerase Activation and ATRX Mutations Are Independent Risk Factors for Metastatic Pheochromocytoma and Paraganglioma. AB - Purpose: Pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumors. Whereas most PPGLs are benign, up to 20% may become metastatic with SDHB- and FH-mutated tumors showing the higher risk. We aimed at determining the contribution of immortalization mechanisms to metastatic progression.Experimental Design: Immortalization mechanisms were investigated in 200 tumors. To identify telomerase (+) tumors, we analyzed genomic alterations leading to transcriptional activation of TERT comprising promoter mutations, hypermethylation and gain copy number. To identify tumors that activated the alternative lengthening of telomere (ALT) mechanism, we combined analyses of telomere length by slot blot, telomere heterogeneity by telomere FISH, and ATRX mutations by next-generation sequencing. Univariate/multivariate and metastasis-free survival (MFS) and overall survival (OS) analyses were carried out for assessment of risk factors and clinical outcomes.Results: Only 37 of 200 (18.5%) tumors achieved immortalization. Telomerase activation occurred in 12 metastatic tumors and was prevalent in SDHB mutated paragangliomas (P = 2.42e-09). ALT features were present in 25 tumors, mostly pheochromocytomas, regardless of metastatic status or molecular group (P = 0.169), yet ATRX mutations were found preferentially in SDHB/FH-mutated metastatic tumors (P = 0.0014). Telomerase activation and ATRX mutations were independent factors of poor prognosis: MFS (hazard ratio, 48.2 and 33.1; P = 6.50E-07 and 1.90E-07, respectively); OS (hazard ratio, 97.4 and 44.1; P = 4.30E 03 and 2.00E-03, respectively) and were associated with worse MFS and OS (log rank tests P < 0.0001).Conclusions: Assessment of telomerase activation and ATRX mutations could be used to identify metastatic PPGLs, particularly in tumors at high risk of progression.

PMID- 30301829 TI - Expression of AR-V7 and ARv567es in circulating tumor cells correlates with outcomes to taxane therapy in men with metastatic prostate cancer treated in TAXYNERGY. AB - PURPOSE: Biomarkers aiding treatment optimization in metastatic castration resistant prostate cancer (mCRPC) are scarce. Presence or absence of androgen receptor (AR) splice variants, AR-V7 and ARv567es, in mCRPC patient circulating tumor cells (CTCs) may be associated with taxane treatment outcomes. METHODS: A novel digital droplet PCR (ddPCR) assay assessed AR splice variant expression in patient CTCs receiving docetaxel or cabazitaxel in TAXYNERGY (NCT01718353). Outcomes were examined according to AR splice variant expression, including prostate-specific antigen (PSA)50 response and progression-free survival (PFS). RESULTS: Of 54 evaluable patients, 36 (67%) were AR-V7+, 42 (78%) ARv567es+, 29 (54%) double positive and 5 (9%) double negative. PSA50 response rates at any time were numerically higher for AR-V7- vs AR-V7+ (78% vs 58%; p=0.23) and for ARv567es- vs ARv567es+ (92% vs 57%; p=0.04) patients. When AR-V mRNA status was correlated with change in nuclear AR from Cycle 1 Day 1 to 8 (n=24), AR-V7+ patients (n=16) had a 0.4% decrease vs a 12.9% and 26.7% decrease in AR-V7 /ARv567es- (n=3) and AR-V7-/ ARv567es+ (n=5) patients, respectively, suggesting a dominant role for AR-V7 over ARv567es.Median PFS was 12.02 vs 8.48 months for AR V7- vs AR-V7+ (HR=0.38; p=0.01), and 12.71 vs 7.29 months for ARv567es- vs ARv567es+ (HR=0.37; p=0.02). For AR-V7+, AR-V7-/ARv567es+, and AR-V7-/ ARv567es- patients, median PFS was 8.48, 11.17 and 16.62 months, respectively (trend: p=0.0013). CONCLUSIONS: Detection of CTC-specific AR-V7 and ARv567es by ddPCR influenced taxane outcomes; AR-V7 primarily mediated the prognostic impact. Absence of both variants was associated with best response and PFS with taxanes. PMID- 30301830 TI - Congolese gynaecologist shares Nobel peace prize for work with war rape victims.

AB - Posttranscriptional modifications of rRNA occur in the nucleolus where rRNA modification guide RNAs, or snoRNAs, concentrate. On the other hand, scaRNAs, the modification guide RNAs for spliceosomal snRNAs, concentrate in the Cajal body (CB). It is generally assumed, therefore, that snRNAs must accumulate in CBs to be modified by scaRNAs. Here we demonstrate that the evidence for the latter postulate is not consistent. In the nucleus, scaRNA localization is not limited to CBs. Furthermore, canonical scaRNAs can modify rRNAs. We suggest that the conventional view that scaRNAs function only in the CB needs revision.

PMID- 30301834 TI - Red cell distribution width in coronary heart disease: prediction of restenosis and its relationship with inflammatory markers and lipids. AB - BACKGROUND: Red cell distribution width (RDW) is associated with a poor prognosis and adverse events in cardiovascular diseases. The aims of this study were to investigate the relationship between serum RDW levels and outcomes after percutaneous coronary intervention and to identify potential novel laboratory markers for evaluating the risk of in-stent restenosis (ISR) with stable angina pectoris. METHODS: A total of 261 patients with coronary heart disease from Dongfeng General Hospital implanted with a coronary drug-eluting stent (DES) were enrolled in the study. We retrospectively analysed the role and prognosis values of serum parameters that were measured before angiography at the first admission. According to the results of the second angiogram, the patients were divided into two groups as follows: the non-ISR group (n=143) and the ISR group (n=118). The clinical characteristics and all laboratory data were considered for univariate and multivariate logistic regression analyses. RESULTS: The white cell count, RDW, neutrophil count, C-reactive protein (CRP), total cholesterol, low-density lipoprotein cholesterol (LDL-C), blood urea nitrogen and uric acid levels were higher in the ISR group than in the non-ISR group. There were no differences in the rates of hypertension, fasting plasma glucose, red cell count, neutrophil to lymphocyte ratio, platelet count, triglyceride, high-density lipoprotein cholesterol and creatinine levels. In the univariate regression analysis, age, diabetes, white cell count, neutrophil count, RDW, CRP, total cholesterol, LDL-C, blood urea nitrogen, Gensini score and number of stents were predictors of ISR. According to the multiple logistic regression analysis, age, RDW and number of stents were independent predictors of ISR. CONCLUSIONS: Preprocedural blood parameters can independently predict ISR. Our study results demonstrated that a high preprocedural RDW is an independent predictor of DES restenosis. PMID- 30301835 TI - A long wait: barriers to discharge for long length of stay patients. AB - INTRODUCTION: Reducing long length of stay (LLOS, or inpatient stays lasting over 30 days) is an important way for hospitals to improve cost efficiency, bed availability and health outcomes. Discharge delays can cost hundreds to thousands of dollars per patient, and LLOS represents a burden on bed availability for other potential patients. However, most research studies investigating discharge barriers are not LLOS-specific. Of those that do, nearly all are limited by further patient subpopulation focus or small sample size. To our knowledge, our study is the first to describe LLOS discharge barriers in an entire Department of Medicine. METHODS: We conducted a chart review of 172 LLOS patients in the Department of Medicine at an academic tertiary care hospital and quantified the most frequent causes of delay as well as factors causing the greatest amount of delay time. We also interviewed healthcare staff for their perceptions on barriers to discharge. RESULTS: Discharge site coordination was the most frequent cause of delay, affecting 56% of patients and accounting for 80% of total non medical postponement days. Goals of care issues and establishment of follow-up care were the next most frequent contributors to delay. CONCLUSION: Together with perspectives from interviewed staff, these results highlight multiple different areas of opportunity for reducing LLOS and maximising the care capacity of inpatient hospitals.

AB - T cell factor, the effector transcription factor of the WNT signaling pathway, was so named because of the primary observation that it is indispensable for T cell development in the thymus. Since this discovery, the role of this signaling pathway has been extensively studied in T cell development, hematopoiesis, and stem cells; however, its functional role in mature T cells has remained relatively underinvestigated. Over the last few years, various studies have demonstrated that T cell factor can directly influence T cell function and the differentiation of Th1, Th2, Th17, regulatory T cell, follicular helper CD4+ T cell subsets, and CD8+ memory T cells. In this paper, we discuss the molecular mechanisms underlying these observations and place them in the general context of immune responses. Furthermore, we explore the implications and limitations of these findings for WNT manipulation as a therapeutic approach for treating immune related diseases. PMID- 30301838 TI - A multimodal molecular imaging study evaluates pharmacological alteration of the tumor microenvironment to improve radiation response. AB - Hypoxic zones in solid tumors contribute to radioresistance, and pharmacological agents that increase tumor oxygenation prior to radiation, including anti angiogenic drugs, can enhance treatment response to radiotherapy. Although such strategies have been applied, imaging assessments of tumor oxygenation to identify an optimum time window for radiotherapy have not been fully explored. In this study, we investigated the effects of alpha-sulfoquinovosylacyl-1,3 propanediol (SQAP; a synthetic derivative of an anti-angiogenic agent) on the tumor microenvironment in terms of oxygen partial pressure (pO2), oxyhemoglobin saturation (sO2), blood perfusion, and microvessel density using electron paramagnetic resonance imaging, photoacoustic imaging, dynamic contrast-enhanced MRI with Gd-DTPA injection, and T2*-weighted imaging with ultrasmall superparamagnetic iron oxide (USPIO) contrast. SCCVII and A549 tumors were grown by injecting tumor cells into the hind legs of mice. Five days of daily radiation (2 Gy) combined with intravenous injection of SQAP (2 mg/kg) 30 min prior to irradiation significantly delayed growth of tumor xenografts. Three days of daily treatment improved tumor oxygenation and decreased tumor microvascular density on T2*-weighted images with USPIO, suggesting vascular normalization. Acute effects of SQAP on tumor oxygenation were examined by pO2, sO2, and Gd-DTPA contrast enhanced imaging. SQAP treatment improved perfusion and tumor pO2 (DeltapO2: 3.1+/-1.0 mmHg) and was accompanied by decreased sO2 (20-30% decrease) in SCCVII implants 20-30 min after SQAP administration. These results provide evidence that SQAP transiently enhances tumor oxygenation by facilitating oxygen dissociation from oxyhemoglobin and improving tumor perfusion. Therefore, SQAP-mediated sensitization to radiation in vivo can be attributed to increased tumor oxygenation. PMID- 30301839 TI - LPA4-Mediated Vascular Network Formation Increases the Efficacy of Anti-PD-1 Therapy against Brain Tumors. AB - : The structure and function of tumor blood vessels profoundly affects the tumor microenvironment. Signals mediated through the lysophosphatidic acid receptor 4 (LPA4) promote vascular network formation to restore normal vascular barrier function in subcutaneous tumors and thus improve drug delivery. However, the characteristics of the vasculature vary by organ and tumor types, and how drug delivery and leukocyte trafficking are affected by modification of vascular function by LPA in different cancers is unclear. Here, we show that LPA4 activation promotes the formation of fine vascular structures in brain tumors. RhoA/ROCK signaling contributed to LPA-induced endothelial cell-cell adhesion, and RhoA/ROCK activity following LPA4 stimulation regulated expression of VCAM-1. This resulted in increased lymphocyte infiltration into the tumor. LPA improved delivery of exogenous IgG into brain tumors and enhanced the anticancer effect of anti-programmed cell death-1 antibody therapy. These results indicate the effects of LPA on vascular structure and function apply not only to chemotherapy but also to immunotherapy. SIGNIFICANCE: These findings demonstrate that lysophosphatidic acid, a lipid mediator, promotes development of a fine capillary network in brain tumors by inducing tightening of endothelial cell-to-cell adhesion, facilitating improved drug delivery, and lymphocyte penetration. PMID- 30301840 TI - A p53-Responsive miRNA Network Promotes Cancer Cell Quiescence. AB - : Cancer cells in quiescence (G0 phase) are resistant to death, and re-entry of quiescent cancer cells into the cell-cycle plays an important role in cancer recurrence. Here we show that two p53-responsive miRNAs utilize distinct but complementary mechanisms to promote cancer cell quiescence by facilitating stabilization of p27. Purified quiescent B16 mouse melanoma cells expressed higher levels of miRNA-27b-3p and miRNA-455-3p relative to their proliferating counterparts. Induction of quiescence resulted in increased levels of these miRNAs in diverse types of human cancer cell lines. Inhibition of miRNA-27b-3p or miRNA-455-3p reduced, whereas its overexpression increased, the proportion of quiescent cells in the population, indicating that these miRNAs promote cancer cell quiescence. Accordingly, cancer xenografts bearing miRNA-27b-3p or miRNA-455 3p mimics were retarded in growth. miRNA-27b-3p targeted cyclin-dependent kinase regulatory subunit 1 (CKS1B), leading to reduction in p27 polyubiquitination mediated by S-phase kinase-associated protein 2 (Skp2). miRNA-455-3p targeted CDK2-associated cullin domain 1 (CAC1), which enhanced CDK2-mediated phosphorylation of p27 necessary for its polyubiquitination. Of note, the gene encoding miRNA-27b-3p was embedded in the intron of the chromosome 9 open reading frame 3 gene that was transcriptionally activated by p53. Similarly, the host gene of miRNA-455-3p, collagen alpha-1 (XXVII) chain, was also a p53 transcriptional target. Collectively, our results identify miRNA-27b-3p and miRNA 455-3p as important regulators of cancer cell quiescence in response to p53 and suggest that manipulating miRNA-27b-3p and miRNA-455-3p may constitute novel therapeutic avenues for improving outcomes of cancer treatment. SIGNIFICANCE: Two novel p53-responsive microRNAs whose distinct mechanisms of action both stabilize p27 to promote cell quiescence and may serve as therapeutic avenues for improving outcomes of cancer treatment. PMID- 30301841 TI - Probing the mechanisms of extracellular vesicle biogenesis and function in cancer. AB - Tumor cells interact with each other, and their surroundings, using a variety of mechanisms to promote virtually all aspects of cancer progression. One such form of intercellular communication that has been attracting considerable attention from the cancer community and the pharmaceutical industry in recent years involves the ability of cancer cells to generate multiple distinct types of non classical secretory vesicles, generally referred to as extracellular vesicles (EVs). Microvesicles (MVs) represent one of the major classes of EVs and are formed as a result of the outward budding and fission of the plasma membrane. The other main class of EVs is exosomes, which are generated when multivesicular bodies fuse with the cell surface and release their contents into the extracellular space. Both MVs and exosomes have been shown to contain bioactive cargo, including proteins, metabolites, RNA transcripts, microRNAs, and DNA that can be transferred to other cancer cells and stimulate their growth, survival, and migration. However, cancer cell-derived EVs also play important roles in helping re-shape the tumor microenvironment to support tumor expansion and invasive activity, dampen immune responses, as well as enter the circulation to help promote metastatic spread. Here, we provide an overview of what is currently known regarding how the different classes of EVs are generated and contribute to various cancer cell phenotypes. Moreover, we highlight how some of the unique properties of EVs are being used for the development of novel diagnostic and clinical applications. PMID- 30301843 TI - Mimicry and functions of photosynthetic reaction centers. AB - The structure and function of photosynthetic reaction centers (PRCs) have been modeled by designing and synthesizing electron donor-acceptor ensembles including electron mediators, which can mimic multi-step photoinduced charge separation occurring in PRCs to obtain long-lived charge-separated states. PRCs in photosystem I (PSI) or/and photosystem II (PSII) have been utilized as components of solar cells to convert solar energy to electric energy. Biohybrid photoelectrochemical cells composed of PSII have also been developed for solar driven water splitting into H2 and O2 Such a strategy to bridge natural photosynthesis with artificial photosynthesis is discussed in this minireview. PMID- 30301844 TI - New perspectives on IL-33 and IL-1 family cytokines as innate environmental sensors. AB - Interleukin (IL)-1 family cytokines are important initiators of innate immunity and host defence; however, their uncontrolled activities can cause tissue damaging inflammation. Consequently, IL-1 family cytokines have sophisticated regulatory mechanisms to control their activities including proteolytic processing for their activation and the deployment of soluble receptors and receptor antagonists to limit their activities. IL-33 is a promoter of type 2 immunity and allergic inflammation through its alarmin activity that can rapidly initiate local immune responses by stimulating innate immune cells following exposure to environmental insults, pathogens, or sterile injury. Recent publications have provided new insights into how the range and duration of IL-33 activity is regulated by direct sensing of host-derived and exogenous proteolytic activities as well as oxidative changes during tissue damage. Here, we discuss how this impacts our understanding of the roles of IL-33 in initiating immune responses and the evidence that these sensing mechanisms might regulate the activities of other IL-1 family cytokines and their biological functions. Finally, we discuss translational challenges these discoveries pose for the accurate detection of different forms of these cytokines. PMID- 30301845 TI - Allostery and dynamics in small G proteins. AB - The Ras family of small guanine nucleotide-binding proteins behave as molecular switches: they are switched off and inactive when bound to GDP but can be activated by GTP binding in response to signal transduction pathways. Early structural analysis showed that two regions of the protein, which change conformation depending on the nucleotide present, mediate this switch. A large number of X-ray, NMR and simulation studies have shown that this is an over simplification. The switch regions themselves are highly dynamic and can exist in distinct sub-states in the GTP-bound form that have different affinities for other proteins. Furthermore, regions outside the switches have been found to be sensitive to the nucleotide state of the protein, indicating that allosteric change is more widespread than previously thought. Taken together, the accrued knowledge about small G protein structures, allostery and dynamics will be essential for the design and testing of the next generation of inhibitors, both orthosteric and allosteric, as well as for understanding their mode of action. PMID- 30301842 TI - Vitamin C and immune cell function in inflammation and cancer. AB - Vitamin C (ascorbate) is maintained at high levels in most immune cells and can affect many aspects of the immune response. Intracellular levels generally respond to variations in plasma ascorbate availability, and a combination of inadequate intake and increased turnover during severe stress can result in low plasma ascorbate status. Intracellular ascorbate supports essential functions and, in particular, acts as an enzyme cofactor for Fe- or Cu-containing oxygenases. Newly discovered enzymes in this family regulate cell metabolism and epigenetics, and dysregulation of their activity can affect cell phenotype, growth and survival pathways, and stem cell phenotype. This brief overview details some of the recent advances in our understanding of how ascorbate availability can affect the hydroxylases controlling the hypoxic response and the DNA and histone demethylases. These processes play important roles in the regulation of the immune system, altering cell survival pathways, metabolism and functions. PMID- 30301847 TI - Is mitochondrial gene expression coordinated or stochastic? AB - Mitochondrial biogenesis is intimately dependent on the coordinated expression of the nuclear and mitochondrial genomes that is necessary for the assembly and function of the respiratory complexes to produce most of the energy required by cells. Although highly compacted in animals, the mitochondrial genome and its expression are essential for survival, development, and optimal energy production. The machinery that regulates gene expression within mitochondria is localised within the same compartment and, like in their ancestors, the bacteria, this machinery does not use membrane-based compartmentalisation to order the gene expression pathway. Therefore, the lifecycle of mitochondrial RNAs from transcription through processing, maturation, translation to turnover is mediated by a gamut of RNA-binding proteins (RBPs), all contained within the mitochondrial matrix milieu. Recent discoveries indicate that multiple processes regulating RNA metabolism occur at once but since mitochondria have a new complement of RBPs, many evolved de novo from nuclear genes, we are left wondering how co-ordinated are these processes? Here, we review recently identified examples of the co ordinated and stochastic processes that govern the mitochondrial transcriptome. These new discoveries reveal the complexity of mitochondrial gene expression and the need for its in-depth exploration to understand how these organelles can respond to the energy demands of the cell. PMID- 30301846 TI - Towards a therapy for mitochondrial disease: an update. AB - Preclinical work aimed at developing new therapies for mitochondrial diseases has recently given new hopes and opened unexpected perspectives for the patients affected by these pathologies. In contrast, only minor progresses have been achieved so far in the translation into the clinics. Many challenges are still ahead, including the need for a better characterization of the pharmacological effects of the different approaches and the design of appropriate clinical trials with robust outcome measures for this extremely heterogeneous, rare, and complex group of disorders. In this review, we will discuss the most important achievements and the major challenges in this very dynamic research field. PMID- 30301848 TI - The Multifaceted Antibacterial Mechanisms of the Pioneering Peptide Antibiotics Tyrocidine and Gramicidin S. AB - Cyclic beta-sheet decapeptides from the tyrocidine group and the homologous gramicidin S were the first commercially used antibiotics, yet it remains unclear exactly how they kill bacteria. We investigated their mode of action using a bacterial cytological profiling approach. Tyrocidines form defined ion-conducting pores, induce lipid phase separation, and strongly reduce membrane fluidity, resulting in delocalization of a broad range of peripheral and integral membrane proteins. Interestingly, they also cause DNA damage and interfere with DNA binding proteins. Despite sharing 50% sequence identity with tyrocidines, gramicidin S causes only mild lipid demixing with minor effects on membrane fluidity and permeability. Gramicidin S delocalizes peripheral membrane proteins involved in cell division and cell envelope synthesis but does not affect integral membrane proteins or DNA. Our results shed a new light on the multifaceted antibacterial mechanisms of these antibiotics and explain why resistance to them is virtually nonexistent.IMPORTANCE Cyclic beta-sheet decapeptides, such as tyrocidines and gramicidin S, were among the first antibiotics in clinical application. Although they have been used for such a long time, there is virtually no resistance to them, which has led to a renewed interest in this peptide class. Both tyrocidines and gramicidin S are thought to disrupt the bacterial membrane. However, this knowledge is mainly derived from in vitro studies, and there is surprisingly little knowledge about how these long established antibiotics kill bacteria. Our results shed new light on the antibacterial mechanism of beta-sheet peptide antibiotics and explain why they are still so effective and why there is so little resistance to them. PMID- 30301849 TI - Rethinking the Coral Microbiome: Simplicity Exists within a Diverse Microbial Biosphere. AB - Studies of the coral microbiome predominantly characterize the microbial community of the host species as a collective, rather than that of the individual. This ecological perspective on the coral microbiome has led to the conclusion that the coral holobiont is the most diverse microbial biosphere studied thus far. However, investigating the microbiome of the individual, rather than that of the species, highlights common and conserved community attributes which can provide insights into the significance of microbial associations to the host. Here, we show there are consistent characteristics between individuals in the proposed three components of the coral microbiome (i.e., "environmentally responsive community," "resident or individual microbiome," and "core microbiome"). We found that the resident microbiome of a photoendosymbiotic coral harbored <3% (~605 phylotypes) of the 16S rRNA phylotypes associated with all investigated individuals of that species ("species-specific microbiome") (~21,654 phylotypes; individuals from Pachyseris speciosa [n = 123], Mycedium elephantotus [n = 95], and Acropora aculeus [n = 91] from 10 reef locations). The remaining bacterial phylotypes (>96%) (environmentally responsive community) of the species specific microbiome were in fact not found in association with the majority of individuals of the species. Only 0.1% (~21 phylotypes) of the species-specific microbiome of each species was shared among all individuals of the species (core microbiome), equating to ~3.4% of the resident microbiome. We found taxonomic redundancy and consistent patterns of composition, structure, and taxonomic breadth across individual microbiomes from the three coral species. Our results demonstrate that the coral microbiome is structured at the individual level.IMPORTANCE We propose that the coral holobiont should be conceptualized as a diverse transient microbial community that is responsive to the surrounding environment and encompasses a simple, redundant, resident microbiome and a small conserved core microbiome. Most importantly, we show that the coral microbiome is comparable to the microbiomes of other organisms studied thus far. Accurately characterizing the coral-microbe interactions provides an important baseline from which the functional roles and the functional niches within which microbes reside can be deciphered. PMID- 30301850 TI - Arylvinylpiperazine Amides, a New Class of Potent Inhibitors Targeting QcrB of Mycobacterium tuberculosis. AB - New drugs are needed to control the current tuberculosis (TB) pandemic caused by infection with Mycobacterium tuberculosis We report here on our work with AX-35, an arylvinylpiperazine amide, and four related analogs, which are potent antitubercular agents in vitro All five compounds showed good activity against M. tuberculosis in vitro and in infected THP-1 macrophages, while displaying only mild cytotoxicity. Isolation and characterization of M. tuberculosis-resistant mutants to the arylvinylpiperazine amide derivative AX-35 revealed mutations in the qcrB gene encoding a subunit of cytochrome bc 1 oxidase, one of two terminal oxidases of the electron transport chain. Cross-resistance studies, allelic exchange, transcriptomic analyses, and bioenergetic flux assays provided conclusive evidence that the cytochrome bc 1 -aa 3 is the target of AX-35, although the compound appears to interact differently with the quinol binding pocket compared to previous QcrB inhibitors. The transcriptomic and bioenergetic profiles of M. tuberculosis treated with AX-35 were similar to those generated by other cytochrome bc 1 oxidase inhibitors, including the compensatory role of the alternate terminal oxidase cytochrome bd in respiratory adaptation. In the absence of cytochrome bd oxidase, AX-35 was bactericidal against M. tuberculosis Finally, AX-35 and its analogs were active in an acute mouse model of TB infection, with two analogs displaying improved activity over the parent compound. Our findings will guide future lead optimization to produce a drug candidate for the treatment of TB and other mycobacterial diseases, including Buruli ulcer and leprosy.IMPORTANCE New drugs against Mycobacterium tuberculosis are urgently needed to deal with the current global TB pandemic. We report here on the discovery of a series of arylvinylpiperazine amides (AX-35 to AX-39) that represent a promising new family of compounds with potent in vitro and in vivo activities against M. tuberculosis AX compounds target the QcrB subunit of the cytochrome bc 1 terminal oxidase with a different mode of interaction compared to those of known QcrB inhibitors. This study provides the first multifaceted validation of QcrB inhibition by recombineering-mediated allelic exchange, gene expression profiling, and bioenergetic flux studies. It also provides further evidence for the compensatory role of cytochrome bd oxidase upon QcrB inhibition. In the absence of cytochrome bd oxidase, AX compounds are bactericidal, an encouraging property for future antimycobacterial drug development. PMID- 30301852 TI - A Natural History of Actinic Keratosis and Cutaneous Squamous Cell Carcinoma Microbiomes. AB - Cutaneous squamous cell carcinoma (SCC) is the second-most-common cancer in Australia. The majority of SCCs progress from premalignant actinic keratosis (AK) lesions that form on chronically sun-exposed skin. The role of skin microbiota in this progression is not well understood; therefore, we performed a longitudinal microbiome analysis of AKs and SCCs using a cohort of 13 SCC-prone immunocompetent men. The majority of variability in microbial profiles was attributable to subject, followed by time and lesion type. Propionibacterium and Malassezia organisms were relatively more abundant in nonlesional photodamaged skin than in AKs and SCCs. Staphylococcus was most commonly associated with lesional skin, in particular, sequences most closely related to Staphylococcus aureus Of 11 S. aureus-like operational taxonomic units (OTUs), six were significantly associated with SCC lesions across seven subjects, suggesting their specific involvement with AK-to-SCC progression. If a causative link exists between certain S. aureus-like OTUs and SCC etiology, therapeutic approaches specifically targeting these bacteria could be used to reduce SCC.IMPORTANCE Actinic keratosis (AK) and cutaneous squamous cell carcinoma (SCC) are two of the most common dermatologic conditions in Western countries and cause substantial morbidity worldwide. The role of human papillomaviruses under these conditions has been well studied yet remains inconclusive. One PCR-based study has investigated bacteria in the etiology of these conditions; however, no study has investigated the microbiomes of AK and SCC more broadly. We longitudinally profiled the microbiomes of 112 AK lesions, profiled cross sections of 32 spontaneously arising SCC lesions, and compared these to matching nonlesional photodamaged control skin sites. We identified commonly occurring strains of Propionibacterium and Malassezia at higher relative abundances on nonlesional skin than in AK and SCC lesions, and strains of Staphylococcus aureus were relatively more abundant in lesional than nonlesional skin. These findings may aid in the prevention of SCC. PMID- 30301851 TI - Evolution of the Arsenal of Legionella pneumophila Effectors To Modulate Protist Hosts. AB - Within the human host, Legionella pneumophila replicates within alveolar macrophages, leading to pneumonia. However, L. pneumophila is an aquatic generalist pathogen that replicates within a wide variety of protist hosts, including amoebozoa, percolozoa, and ciliophora. The intracellular lifestyles of L. pneumophila within the two evolutionarily distant hosts macrophages and protists are remarkably similar. Coevolution with numerous protist hosts has shaped plasticity of the genome of L. pneumophila, which harbors numerous proteins encoded by genes acquired from primitive eukaryotic hosts through interkingdom horizontal gene transfer. The Dot/Icm type IVb translocation system translocates ~6,000 effectors among Legionella species and >320 effector proteins in L. pneumophila into host cells to modulate a plethora of cellular processes to create proliferative niches. Since many of the effectors have likely evolved to modulate cellular processes of primitive eukaryotic hosts, it is not surprising that most of the effectors do not contribute to intracellular growth within human macrophages. Some of the effectors may modulate highly conserved eukaryotic processes, while others may target protist-specific processes that are absent in mammals. The lack of studies to determine the role of the effectors in adaptation of L. pneumophila to various protists has hampered the progress to determine the function of most of these effectors, which are routinely studied in mouse or human macrophages. Since many protists restrict L. pneumophila, utilization of such hosts can also be instrumental in deciphering the mechanisms of failure of L. pneumophila to overcome restriction of certain protist hosts. Here, we review the interaction of L. pneumophila with its permissive and restrictive protist environmental hosts and outline the accomplishments as well as gaps in our knowledge of L. pneumophila-protist host interaction and L. pneumophila's evolution to become a human pathogen. PMID- 30301854 TI - Pathogenicity of Serratia marcescens Strains in Honey Bees. AB - Although few honey bee diseases are known to be caused by bacteria, pathogens of adult worker bees may be underrecognized due to social immunity mechanisms. Specifically, infected adult bees typically abandon the hive or are removed by guards. Serratia marcescens, an opportunistic pathogen of many plants and animals, is often present at low abundance in the guts of honey bee workers and has recently been isolated from Varroa mites and from the hemolymph of dead and dying honey bees. However, the severity and prevalence of S. marcescens pathogenicity in honey bees have not been fully investigated. Here we characterized three S. marcescens strains isolated from the guts of honey bees and one previously isolated from hemolymph. In vivo tests confirmed that S. marcescens is pathogenic in workers. All strains caused mortality when a few cells were injected into the hemocoel, and the gut-isolated strains caused mortality when administered orally. In vitro assays and comparative genomics identified possible mechanisms of virulence of gut-associated strains. Expression of antimicrobial peptide and phenoloxidase genes was not elevated following infection, suggesting that these S. marcescens strains derived from honey bees can evade the immune response in their hosts. Finally, surveys from four locations in the United States indicated the presence of S. marcescens in the guts of over 60% of the worker bees evaluated. Taken together, these results suggest that S. marcescens is a widespread opportunistic pathogen of adult honey bees and that it may be highly virulent under some conditions such as perturbation of the normal gut microbiota or the presence of Varroa mites that puncture the integument, thereby enabling entry of bacterial cells.IMPORTANCE Recently, it has become apparent that multiple factors are responsible for honey bee decline, including climate change, pests and pathogens, pesticides, and loss of foraging habitat. Of the large number of pathogens known to infect honey bees, very few are bacteria. Because adult workers abandon hives when diseased, many of their pathogens may go unnoticed. Here we characterized the virulence of Serratia marcescens strains isolated from honey bee guts and hemolymph. Our results indicate that S. marcescens, an opportunistic pathogen of many plants and animals, including humans, is a virulent opportunistic pathogen of honey bees, which could contribute to bee decline. Aside from the implications for honey bee health, the discovery of pathogenic S. marcescens strains in honey bees presents an opportunity to better understand how opportunistic pathogens infect and invade hosts. PMID- 30301853 TI - Octopaminergic Signaling Mediates Neural Regulation of Innate Immunity in Caenorhabditis elegans. AB - Upon pathogen infection, the nervous system regulates innate immunity to confer coordinated protection to the host. However, the precise mechanisms of such regulation remain unclear. Previous studies have demonstrated that OCTR-1, a putative G protein-coupled receptor for catecholamine, functions in the sensory neurons designated "ASH" to suppress innate immune responses in Caenorhabditis elegans It is unknown what molecules act as OCTR-1 ligands in the neural immune regulatory circuit. Here we identify neurotransmitter octopamine (OA) as an endogenous ligand for OCTR-1 in immune regulation and show that the OA-producing RIC neurons function in the OCTR-1 neural circuit to suppress innate immunity. RIC neurons are deactivated in the presence of pathogens but transiently activated by nonpathogenic bacteria. Our data support a model whereby an octopaminergic immunoinhibitory pathway is tonically active under normal conditions to maintain immunological homeostasis or suppress unwanted innate immune responses but downregulated upon pathogen infection to allow enhanced innate immunity. As excessive innate immune responses have been linked to a myriad of human health concerns, our study could potentially benefit the development of more-effective treatments for innate immune disorders.IMPORTANCE Insufficient or excessive immune responses to pathogen infection are major causes of disease. Increasing evidence indicates that the nervous system regulates the immune system to help maintain immunological homeostasis. However, the precise mechanisms of this regulation are largely unknown. Here we show the existence of an octopaminergic immunoinhibitory pathway in Caenorhabditis elegans Our study results indicate that this pathway is tonically active under normal conditions to maintain immunological homeostasis or suppress unwanted innate immune responses but downregulated upon pathogen infection to allow enhanced innate immunity. As excessive innate immune responses have been linked to human health conditions such as Crohn's disease, rheumatoid arthritis, atherosclerosis, diabetes, and Alzheimer's disease, elucidating octopaminergic neural regulation of innate immunity could be helpful in the development of new treatments for innate immune diseases. PMID- 30301855 TI - Inducible Nitric Oxide Synthase Is a Key Host Factor for Toxoplasma GRA15 Dependent Disruption of the Gamma Interferon-Induced Antiparasitic Human Response. AB - Although Toxoplasma virulence mechanisms targeting gamma interferon (IFN-gamma) induced cell-autonomous antiparasitic immunity have been extensively characterized in mice, the virulence mechanisms in humans remain uncertain, partly because cell-autonomous immune responses against Toxoplasma differ markedly between mice and humans. Despite the identification of inducible nitric oxide synthase (iNOS) as an anti-Toxoplasma host factor in mice, here we show that iNOS in humans is a pro-Toxoplasma host factor that promotes the growth of the parasite. The GRA15 Toxoplasma effector-dependent disarmament of IFN-gamma induced parasite growth inhibition was evident when parasite-infected monocytes were cocultured with hepatocytes. Interleukin-1beta (IL-1beta), produced from monocytes in a manner dependent on GRA15 and the host's NLRP3 inflammasome, combined with IFN-gamma to strongly stimulate iNOS expression in hepatocytes; this dramatically reduced the levels of indole 2,3-dioxygenase 1 (IDO1), a critically important IFN-gamma-inducible anti-Toxoplasma protein in humans, thus allowing parasite growth. Taking the data together, Toxoplasma utilizes human iNOS to antagonize IFN-gamma-induced IDO1-mediated cell-autonomous immunity via its GRA15 virulence factor.IMPORTANCE Toxoplasma, an important intracellular parasite of humans and animals, causes life-threatening toxoplasmosis in immunocompromised individuals. Gamma interferon (IFN-gamma) is produced in the host to inhibit the proliferation of this parasite and eventually cause its death. Unlike mouse disease models, which involve well-characterized virulence strategies that are used by Toxoplasma to suppress IFN-gamma-dependent immunity, the strategies used by Toxoplasma in humans remain unclear. Here, we show that GRA15, a Toxoplasma effector protein, suppresses the IFN-gamma-induced indole-2,3 dioxygenase 1-dependent antiparasite immune response in human cells. Because NLRP3-dependent production of IL-1beta and nitric oxide (NO) in Toxoplasma infected human cells is involved in the GRA15-dependent virulence mechanism, blocking NO or IL-1beta production in the host could represent a novel therapeutic approach for treating human toxoplasmosis. PMID- 30301856 TI - Complement Activation Contributes to Severe Acute Respiratory Syndrome Coronavirus Pathogenesis. AB - Acute respiratory distress syndrome (ARDS) is immune-driven pathologies that are observed in severe cases of severe acute respiratory syndrome coronavirus (SARS CoV) infection. SARS-CoV emerged in 2002 to 2003 and led to a global outbreak of SARS. As with the outcome of human infection, intranasal infection of C57BL/6J mice with mouse-adapted SARS-CoV results in high-titer virus replication within the lung, induction of inflammatory cytokines and chemokines, and immune cell infiltration within the lung. Using this model, we investigated the role of the complement system during SARS-CoV infection. We observed activation of the complement cascade in the lung as early as day 1 following SARS-CoV infection. To test whether this activation contributed to protective or pathologic outcomes, we utilized mice deficient in C3 (C3-/-), the central component of the complement system. Relative to C57BL/6J control mice, SARS-CoV-infected C3 -/- mice exhibited significantly less weight loss and less respiratory dysfunction despite equivalent viral loads in the lung. Significantly fewer neutrophils and inflammatory monocytes were present in the lungs of C3 -/- mice than in C56BL/6J controls, and subsequent studies revealed reduced lung pathology and lower cytokine and chemokine levels in both the lungs and the sera of C3 -/- mice than in controls. These studies identify the complement system as an important host mediator of SARS-CoV-induced disease and suggest that complement activation regulates a systemic proinflammatory response to SARS-CoV infection. Furthermore, these data suggest that SARS-CoV-mediated disease is largely immune driven and that inhibiting complement signaling after SARS-CoV infection might function as an effective immune therapeutic.IMPORTANCE The complement system is a critical part of host defense to many bacterial, viral, and fungal infections. It works alongside pattern recognition receptors to stimulate host defense systems in advance of activation of the adaptive immune response. In this study, we directly test the role of complement in SARS-CoV pathogenesis using a mouse model and show that respiratory disease is significantly reduced in the absence of complement even though viral load is unchanged. Complement-deficient mice have reduced neutrophilia in their lungs and reduced systemic inflammation, consistent with the observation that SARS-CoV pathogenesis is an immune-driven disease. These data suggest that inhibition of complement signaling might be an effective treatment option following coronavirus infection. PMID- 30301858 TI - Host-Pathogen Interactions: What the EHEC Are We Learning from Host Genome-Wide Screens? AB - Several genome-wide screens have been conducted to identify host cell factors involved in the pathogenesis of bacterial pathogens whose virulence is dependent on type III secretion systems (T3SSs), nanomachines responsible for the translocation of proteins into host cells. In the most recent of these, Pacheco et al. (mBio 9:e01003-18, 2018, http://mbio.asm.org/content/9/3/e01003-18.full) screened a genome-wide CRISPR/Cas9 (clustered regularly interspaced short palindromic repeats with Cas9) knockout library for host proteins involved in the pathogenesis of enterohemorrhagic Escherichia coli (EHEC). Their study revealed an unrecognized link between EHEC's two major virulence determinants (its T3SS and Shiga toxins). We discuss these findings in light of data from three other genome-wide screens. Each of these studies uncovered multiple host cell determinants, which curiously share little to no overlap but primarily are involved in mediating early interactions between T3SSs and host cells. We therefore consider how each screen was performed, the advantages and disadvantages of each, and how follow-up studies might be designed to address these issues. PMID- 30301857 TI - Staufen1 Interacts with Multiple Components of the Ebola Virus Ribonucleoprotein and Enhances Viral RNA Synthesis. AB - Ebola virus (EBOV) genome and mRNAs contain long, structured regions that could hijack host RNA-binding proteins to facilitate infection. We performed RNA affinity chromatography coupled with mass spectrometry to identify host proteins that bind to EBOV RNAs and identified four high-confidence proviral host factors, including Staufen1 (STAU1), which specifically binds both 3' and 5' extracistronic regions of the EBOV genome. We confirmed that EBOV infection rate and production of infectious particles were significantly reduced in STAU1 depleted cells. STAU1 was recruited to sites of EBOV RNA synthesis upon infection and enhanced viral RNA synthesis. Furthermore, STAU1 interacts with EBOV nucleoprotein (NP), virion protein 30 (VP30), and VP35; the latter two bridge the viral polymerase to the NP-coated genome, forming the viral ribonucleoprotein (RNP) complex. Our data indicate that STAU1 plays a critical role in EBOV replication by coordinating interactions between the viral genome and RNA synthesis machinery.IMPORTANCE Ebola virus (EBOV) is a negative-strand RNA virus with significant public health importance. Currently, no therapeutics are available for Ebola, which imposes an urgent need for a better understanding of EBOV biology. Here we dissected the virus-host interplay between EBOV and host RNA-binding proteins. We identified novel EBOV host factors, including Staufen1, which interacts with multiple viral factors and is required for efficient viral RNA synthesis. PMID- 30301859 TI - Modernized Tools for Streamlined Genetic Manipulation and Comparative Study of Wild and Diverse Proteobacterial Lineages. AB - Correlating the presence of bacteria and the genes they carry with aspects of plant and animal biology is rapidly outpacing the functional characterization of naturally occurring symbioses. A major barrier to mechanistic studies is the lack of tools for the efficient genetic manipulation of wild and diverse bacterial isolates. To address the need for improved molecular tools, we used a collection of proteobacterial isolates native to the zebrafish intestinal microbiota as a testbed to construct a series of modernized vectors that expedite genetic knock in and knockout procedures across lineages. The innovations that we introduce enhance the flexibility of conventional genetic techniques, making it easier to manipulate many different bacterial isolates with a single set of tools. We developed alternative strategies for domestication-free conjugation, designed plasmids with customizable features, and streamlined allelic exchange using visual markers of homologous recombination. We demonstrate the potential of these tools through a comparative study of bacterial behavior within the zebrafish intestine. Live imaging of fluorescently tagged isolates revealed a spectrum of distinct population structures that differ in their biogeography and dominant growth mode (i.e., planktonic versus aggregated). Most striking, we observed divergent genotype-phenotype relationships: several isolates that are predicted by genomic analysis and in vitro assays to be capable of flagellar motility do not display this trait within living hosts. Together, the tools generated in this work provide a new resource for the functional characterization of wild and diverse bacterial lineages that will help speed the research pipeline from sequencing-based correlations to mechanistic underpinnings.IMPORTANCE A great challenge in microbiota research is the immense diversity of symbiotic bacteria with the capacity to impact the lives of plants and animals. Moving beyond correlative DNA sequencing-based studies to define the cellular and molecular mechanisms by which symbiotic bacteria influence the biology of their hosts is stalling because genetic manipulation of new and uncharacterized bacterial isolates remains slow and difficult with current genetic tools. Moreover, developing tools de novo is an arduous and time-consuming task and thus represents a significant barrier to progress. To address this problem, we developed a suite of engineering vectors that streamline conventional genetic techniques by improving postconjugation counterselection, modularity, and allelic exchange. Our modernized tools and step-by-step protocols will empower researchers to investigate the inner workings of both established and newly emerging models of bacterial symbiosis. PMID- 30301862 TI - Use mesh implants for stress urinary incontinence only as last resort, says NICE. PMID- 30301863 TI - Histone deacetylase inhibition has targeted clinical benefit in ARID1A mutated advanced urothelial carcinoma. AB - Histone deacetylase (HDAC) inhibition has sporadic clinical efficacy in urothelial carcinoma (UC); the genomic basis for clinical response is not known. In two separate phase I clinical trials testing pharmacokinetic aspects of HDAC inhibitors in advanced solid tumors, we identified one patient with advanced UC who had a complete response (CR) to belinostat, and one patient with advanced UC who had a partial response (PR) to panobinostat. The archived tumors of the responders were genomically characterized in comparison to others with UC on the trials. UC cell lines treated with panobinostat and belinostat were studied to elucidate the mechanisms of benefit. Notably, the UC tumors that responded to HDAC inhibition had ARID1A mutations. ARID1A mutations were also noted in the tumors of three patients who had stable disease as their best response to HDAC inhibition. Corroborating the basis of sensitivity, transcriptional profiling of platinum-resistant ARID1A-mutated HT1197 cells treated with panobinostat reveals negative enrichment for both cyto-proliferative (MYC and E2F targets) and DNA repair gene sets, and positive enrichment for TP53 and inflammatory gene sets. Our study identifies ARID1A loss as a basis for clinical response to pan HDAC inhibition and offers avenues for potential rational therapeutic combinations with HDAC inhibitors in advanced UC. PMID- 30301860 TI - Renal COP9 Signalosome Deficiency Alters CUL3-KLHL3-WNK Signaling Pathway. AB - BACKGROUND: The familial hyperkalemic hypertension (FHHt) cullin 3 (CUL3) mutant does not degrade WNK kinases normally, thereby leading to thiazide-sensitive Na Cl cotransporter (NCC) activation. CUL3 mutant (CUL3Delta9) does not bind normally to the COP9 signalosome (CSN), a deneddylase involved in regulating cullin-RING ligases. CUL3Delta9 also caused increased degradation of the CUL3-WNK substrate adaptor kelch-like 3 (KLHL3). Here, we sought to determine how defective CSN action contributes to the CUL3Delta9 phenotype. METHODS: The Pax8/LC1 mouse system was used to generate mice in which the catalytically active CSN subunit, Jab1, was deleted only along the nephron, after full development (KS Jab1 -/-). RESULTS: Western blot analysis demonstrated that Jab1 deletion increased the abundance of neddylated CUL3. Moreover, total CUL3 expression was reduced, suggesting decreased CUL3 stability. KLHL3 was almost completely absent in KS-Jab1 -/- mice. Conversely, the protein abundances of WNK1, WNK4, and SPAK kinases were substantially higher. Activation of WNK4, SPAK, and OSR1 was indicated by higher phosphorylated protein levels and translocation of the proteins into puncta, as observed by immunofluorescence. The ratio of phosphorylated NCC to total NCC was also higher. Surprisingly, NCC protein abundance was low, likely contributing to hypokalemia and Na+ and K+ wasting. Additionally, long-term Jab1 deletion resulted in kidney damage. CONCLUSIONS: Together, the results indicate that deficient CSN binding contributes importantly to the FHHt phenotype. Although defective CUL3Delta9-faciliated WNK4 degradation likely contributes, dominant effects on KLHL3 may be a second factor that is necessary for the phenotype. PMID- 30301861 TI - Combined Structural and Functional Imaging of the Kidney Reveals Major Axial Differences in Proximal Tubule Endocytosis. AB - BACKGROUND: The kidney proximal convoluted tubule (PCT) reabsorbs filtered macromolecules via receptor-mediated endocytosis (RME) or nonspecific fluid phase endocytosis (FPE); endocytosis is also an entry route for disease-causing toxins. PCT cells express the protein ligand receptor megalin and have a highly developed endolysosomal system (ELS). Two PCT segments (S1 and S2) display subtle differences in cellular ultrastructure; whether these translate into differences in endocytotic function has been unknown. METHODS: To investigate potential differences in endocytic function in S1 and S2, we quantified ELS protein expression in mouse kidney PCTs using real-time quantitative polymerase chain reaction and immunostaining. We also used multiphoton microscopy to visualize uptake of fluorescently labeled ligands in both living animals and tissue cleared using a modified CLARITY approach. RESULTS: Uptake of proteins by RME occurs almost exclusively in S1. In contrast, dextran uptake by FPE takes place in both S1 and S2, suggesting that RME and FPE are discrete processes. Expression of key ELS proteins, but not megalin, showed a bimodal distribution; levels were far higher in S1, where intracellular distribution was also more polarized. Tissue clearing permitted imaging of ligand uptake at single-organelle resolution in large sections of kidney cortex. Analysis of segmented tubules confirmed that, compared with protein uptake, dextran uptake occurred over a much greater length of the PCT, although individual PCTs show marked heterogeneity in solute uptake length and three-dimensional morphology. CONCLUSIONS: Striking axial differences in ligand uptake and ELS function exist along the PCT, independent of megalin expression. These differences have important implications for understanding topographic patterns of kidney diseases and the origins of proteinuria. PMID- 30301865 TI - Monitoring tumor burden in response to FOLFIRINOX chemotherapy via profiling circulating cell-free DNA in pancreatic cancer. AB - We aimed to explore the application of circulating cell-free DNA (cfDNA) profiling in monitoring tumor burden in patients with pancreatic ductal adenocarcinoma (PDAC). Thirty-eight advanced PDAC patients receiving first-line FOLFIRINOX chemotherapy were prospectively enrolled. Next-generation sequencing for a panel of 560 genes covering a wide range of cancer-related loci was performed to profile cfDNA. In total, twenty-five patients (65.8%) had at least one common driver gene alterations (KRAS, TP53, SMAD4, CDKN2A) detected within cfDNA. In contrast, no above tumor-related recurrent mutations were found in plasma from 13 healthy individuals. Concordant alterations in plasma cfDNA and tumor tissue DNA was confirmed in 2 out of 3 patients with available tissues. Further analysis showed that mutant allele fraction (MAF) for altered loci in cfDNA correlated with tumor stage, metastatic burden, and overall survival. Serial blood samples were collected from 17 patients after chemotherapy. We found that allele fraction for specific altered loci declined in chemotherapy responding subjects. For cases who were resistant to this therapeutic regimen, increased ctDNA MAF was observed at the time of disease progression. Meanwhile, the dynamics of total cfDNA concentration correlated with tumor burden following chemotherapy. Collectively, we provide evidence that pre-treatment ctDNA level correlates with tumor burden in PDAC, and serial cfDNA analysis is a robust tool for monitoring cancer response to chemotherapy. PMID- 30301864 TI - ODM-203 a selective inhibitor of FGFR and VEGFR, shows strong anti-tumor activity, and induces anti-tumor immunity. AB - Alterations in the gene encoding for the fibroblast growth factor receptor (FGFR) and upregulation of the vascular endothelial growth factor receptor (VEGFR) are found often in cancer, which correlate with disease progression and unfavorable survival. Additionally, FGFR and VEGFR signaling synergistically promote tumor angiogenesis, and activation of FGFR signaling has been described as functional compensatory angiogenic signal following development of resistance to VEGFR inhibition. Several selective small-molecule FGFR kinase inhibitors are currently in clinical development. ODM-203 is a novel, selective and equipotent inhibitor of the FGFR and VEGFR families. In this report we show that ODM-203 inhibits FGFR and VEGFR family kinases selectively and with equal potency in the low nanomolar range (IC50 6-35 nM) in biochemical assays. In cellular assays, ODM-203 inhibits VEGFR-induced tube formation (IC50 33 nM) with similar potency as it inhibits proliferation in FGFR-dependent cell lines (IC50 50-150 nM). In vivo, ODM-203 shows strong anti-tumor activity in both FGFR-dependent xenograft models and in an angiogenic xenograft model at similar well-tolerated doses. In addition, ODM 203 inhibits metastatic tumor growth in a highly angiogenesis-dependent kidney capsule syngenic model. Interestingly, potent anti-tumor activity in the subcutaneous syngenic model correlated well with immune modulation in the tumor microenvironment as indicated by marked decrease in the expression of immune check points PD-1 and PD-L1 on CD8 T cells and NK cells, and increased activation of CD8 T cells. In summary, ODM-203 shows equipotent activity for both FGFR and VEGFR kinase families and antitumor activity in both FGFR- and angigogenesis- models.

AB - The aim of this study was to investigate the association between fine particulate matter 2.5 (PM2.5) and oral cancer among Taiwanese men. Four linked data sources including the Taiwan Cancer Registry, Adult Preventive Medical Services Database, National Health Insurance Research Database, and Air Quality Monitoring Database were used. Concentrations of sulfur dioxide, carbon monoxide, ozone, NOx (nitrogen monoxide and nitrogen dioxide), coarse particulate matter (PM10-2.5) and PM2.5 in 2009 were assessed in quartiles. A total of 482 659 men aged 40 years and above were included in the analysis. Logistic regression was used to examine the association between PM2.5 and oral cancer diagnosed from 2012 to 2013. After adjusting for potential confounders, the ORs of oral cancer were 0.91 (95% CI 0.75 to 1.11) for 26.74<=PM2.5<32.37, 1.01 (95% CI 0.84 to 1.20) for 32.37<=PM2.5<40.37 ug/m3 and 1.43 (95% CI 1.17 to 1.74) for PM2.5>=40.37 ug/m3 compared with PM2.5<26.74 ug/m3 In this study, there was an increased risk of oral cancer among Taiwanese men who were exposed to higher concentrations of PM2.5. PMID- 30301868 TI - Detection of endometrial precancer by a targeted gynecologic cancer liquid biopsy. AB - Endometrial cancer is the most common gynecologic malignancy in industrialized countries and both its incidence and associated mortality are increasing. The "liquid biopsy" is becoming an important transformative precision oncology tool but barriers intrinsic to blood sampling have limited its use in early cancer detection. We hypothesized that using a more targeted sample for analysis, namely, a uterine lavage, should provide a more sensitive and specific diagnostic test for endometrial cancer. Using a custom 12-gene endometrial cancer panel, molecular analysis of uterine lavage fluid from an asymptomatic 67-year-old female without histopathologic evidence of pre-malignant lesions or cancer in her uterine tissue, revealed two oncogenic PTEN mutations. Ten months later, the patient returned with postmenopausal bleeding and a single microscopic focus of endometrial cancer. DNA isolated and sequenced from laser-capture microdissected tumor tissue revealed the same two PTEN mutations. These mutations were unlikely to occur by chance alone (p<3x10-7). This illustrative case provides the first demonstration that future, tumor-specific mutations can be identified in an asymptomatic individual without clinical or pathologic evidence of cancer by using already established sequencing technologies but targeted sampling methods. This finding provides the basis for new opportunities in early cancer screening, detection and prevention. PMID- 30301869 TI - Nebulin increases thin filament stiffness and force per cross-bridge in slow twitch soleus muscle fibers. AB - Nebulin (Neb) is associated with the thin filament in skeletal muscle cells, but its functions are not well understood. For this goal, we study skinned slow twitch soleus muscle fibers from wild-type (Neb+) and conditional Neb knockout (Neb-) mice. We characterize cross-bridge (CB) kinetics and the elementary steps of the CB cycle by sinusoidal analysis during full Ca2+ activation and observe that Neb increases active tension 1.9-fold, active stiffness 2.7-fold, and rigor stiffness 3.0-fold. The ratio of stiffness during activation and rigor states is 62% in Neb+ fibers and 68% in Neb- fibers. These are approximately proportionate to the number of strongly attached CBs during activation. Because the thin filament length is 15% shorter in Neb- fibers than in Neb+ fibers, the increase in force per CB in the presence of Neb is ~1.5 fold. The equilibrium constant of the CB detachment step (K 2), its rate (k 2), and the rate of the reverse force generation step (k -4) are larger in Neb+ fibers than in Neb- fibers. The rates of the force generation step (k 4) and the reversal detachment step (k -2) change in the opposite direction. These effects can be explained by Le Chatelier's principle: Increased CB strain promotes less force-generating state(s) and/or detached state(s). Further, when CB distributions among the six states are calculated, there is no significant difference in the number of strongly attached CBs between fibers with and without Neb. These results demonstrate that Neb increases force per CB. We also confirm that force is generated by isomerization of actomyosin (AM) from the AM.ADP.Pi state (ADP, adenosine diphophate; Pi, phosphate) to the AM*ADP.Pi state, where the same force is maintained after Pi release to result in the AM*ADP state. We propose that Neb changes the actin (and myosin) conformation for better ionic and hydrophobic/stereospecific AM interaction, and that the effect of Neb is similar to that of tropomyosin.

PMID- 30301873 TI - Sicker patients account for the weekend mortality effect among adult emergency admissions to a large hospital trust. AB - OBJECTIVE: To determine whether the higher weekend admission mortality risk is attributable to increased severity of illness. DESIGN: Retrospective analysis of 4 years weekend and weekday adult emergency admissions to a university teaching hospital in England. OUTCOME MEASURES: 30-day postadmission weekend:weekday mortality ratios adjusted for severity of illness (baseline National Early Warning Score (NEWS)), routes of admission to hospital, transfer to the intensive care unit (ICU) and demographics. RESULTS: Despite similar emergency department daily attendance rates, fewer patients were admitted on weekends (mean admission rate 91/day vs 120/day) because of fewer general practitioner referrals. Weekend admissions were sicker than weekday (mean NEWS 1.8 vs 1.7, p=0.008), more likely to undergo transfer to ICU within 24 hours (4.2% vs 3.0%), spent longer in hospital (median 3 days vs 2 days) and less likely to experience same-day discharge (17.2% vs 21.9%) (all p values <0.001).The crude 30-day postadmission mortality ratio for weekend admission (OR=1.13; 95% CI 1.08 to 1.19) was attenuated using standard adjustment (OR=1.11; 95% CI 1.05 to 1.17). In patients for whom NEWS values were available (90%), the crude OR (1.07; 95% CI 1.01 to 1.13) was not affected with standard adjustment. Adjustment using NEWS alone nullified the weekend effect (OR=1.02; 0.96-1.08).NEWS completion rates were higher on weekends (91.7%) than weekdays (89.5%). Missing NEWS was associated with direct transfer to intensive care bypassing electronic data capture. Missing NEWS in non-ICU weekend patients was associated with a higher mortality and fewer same-day discharges than weekdays. CONCLUSIONS: Patients admitted to hospital on weekends are sicker than those admitted on weekdays. The cause of the weekend effect may lie in community services. PMID- 30301874 TI - Impact of decision aids used during clinical encounters on clinician outcomes and consultation length: a systematic review. AB - BACKGROUND: Clinicians' satisfaction with encounter decision aids is an important component in facilitating implementation of these tools. We aimed to determine the impact of decision aids supporting shared decision making (SDM) during the clinical encounter on clinician outcomes. METHODS: We searched nine databases from inception to June 2017. Randomised clinical trials (RCTs) of decision aids used during clinical encounters with an unaided control group were eligible for inclusion. Due to heterogeneity among included studies, we used a narrative evidence synthesis approach. RESULTS: Twenty-five papers met inclusion criteria including 22 RCTs and 3 qualitative or mixed-methods studies nested in an RCT, together representing 23 unique trials. These trials evaluated healthcare decisions for cardiovascular prevention and treatment (n=8), treatment of diabetes mellitus (n=3), treatment of osteoporosis (n=2), treatment of depression (n=2), antibiotics to treat acute respiratory infections (n=3), cancer prevention and treatment (n=4) and prenatal diagnosis (n=1). Clinician outcomes were measured in only a minority of studies. Clinicians' satisfaction with decision making was assessed in only 8 (and only 2 of them showed statistically significantly greater satisfaction with the decision aid); only three trials asked if clinicians would recommend the decision aid to colleagues and only five asked if clinicians would use decision aids in the future. Outpatient consultations were not prolonged when a decision aid was used in 9 out of 13 trials. The overall strength of the evidence was low, with the major risk of bias related to lack of blinding of participants and/or outcome assessors. CONCLUSION: Decision aids can improve clinicians' satisfaction with medical decision making and provide helpful information without affecting length of consultation time. Most SDM trials, however, omit outcomes related to clinicians' perspective on the decision making process or the likelihood of using a decision aid in the future. PMID- 30301870 TI - Kinetic properties of persistent Na+ current orchestrate oscillatory bursting in respiratory neurons. AB - The rhythmic pattern of breathing depends on the pre-Botzinger complex (preBotC) in the brainstem, a vital circuit that contains a population of neurons with intrinsic oscillatory bursting behavior. Here, we investigate the specific kinetic properties that enable voltage-gated sodium channels to establish oscillatory bursting in preBotC inspiratory neurons, which exhibit an unusually large persistent Na+ current (INaP). We first characterize the kinetics of INaP in neonatal rat brainstem slices in vitro, using whole-cell patch-clamp and computational modeling, and then test the contribution of INaP to rhythmic bursting in live neurons, using the dynamic clamp technique. We provide evidence that subthreshold activation, persistence at suprathreshold potentials, slow inactivation, and slow recovery from inactivation are kinetic features of INaP that regulate all aspects of intrinsic rhythmic bursting in preBotC neurons. The slow and cumulative inactivation of INaP during the burst active phase controls burst duration and termination, while the slow recovery from inactivation controls the duration of the interburst interval. To demonstrate this mechanism, we develop a Markov state model of INaP that explains a comprehensive set of voltage clamp data. By adding or subtracting a computer-generated INaP from a live neuron via dynamic clamp, we are able to convert nonbursters into intrinsic bursters, and vice versa. As a control, we test a model with inactivation features removed. Adding noninactivating INaP into nonbursters results in a pattern of random transitions between sustained firing and quiescence. The relative amplitude of INaP is the key factor that separates intrinsic bursters from nonbursters and can change the fraction of intrinsic bursters in the preBotC. INaP could thus be an important target for regulating network rhythmogenic properties. PMID- 30301875 TI - Non-Surgical Management of Colo-Colonic Intussusception in Patients with Hereditary Angioedema. AB - BACKGROUND Hereditary angioedema (HAE) is an autosomal disease caused either by deficiency or presence of a non-functioning C1 inhibitor. The lack or non functionality of said inhibitors leads to activation of an inflammatory cascade, which result in cutaneous and mucosal edema. Most patients with HAE present with either cutaneous, laryngeal/pharyngeal, or gastrointestinal exacerbations. An uncommon gastrointestinal manifestation of HAE is an intussusception, which in most cases require invasive/surgical management. CASE REPORT A 17-year-old Hispanic female patient with past medical history of HAE, presented with a 4-day history of episodic abdominal pain, worsening during the last 2 days with associated nausea, vomiting, and bright red blood per rectum. The abdominal ultrasound performed at our institution showed an elongated region of hypoechoic and hyperechoic concentric rings, raising suspicion of an intussusception. The patient was treated conservatively, with 30 mg of ecallantide and a unit of fresh frozen plasma (FFP). Follow-up abdominopelvic computed tomography scan was performed approximately 20 hours after the administration of fresh frozen plasma revealing complete interval resolution of the colo-colonic intussusception. Subsequently, the patient was kept under hospital care for the next 4 days with adequate progression of diet and without recurrence of intussusception. CONCLUSIONS To the best of our knowledge, most cases of patient with HAE presenting with intussusception have been treated with invasive/surgical procedures. In our case, conservative management has proven successful to reduce edema with subsequent non-surgical reduction of the intussusception. By directly targeting the pathophysiologic aspects of HAE, an unnecessary invasive procedure, as well as its potential complications, were avoided. PMID- 30301876 TI - Activation of Pelvic Floor Muscle During Ankle Posture Change on the Basis of a Three-Dimensional Motion Analysis System. AB - BACKGROUND Weak pelvic floor muscles (PFMs) is an important cause of stress urinary incontinence. Effective strengthening of PFMs is very helpful in improving lower urinary tract disease. The purpose of this study was to determine the activation of PFMs in accordance with movement of the pelvis and ankle. MATERIAL AND METHODS Fifty healthy adults who underwent PFM contraction in ankle posture change (dorsiflexion, neutral, and plantar flexion) while standing were simultaneously measured using electromyography and motion capture systems. Muscle activity at the tibialis anterior and gastrocnemius muscles was measured by surface electromyography electrodes and PFMs was measured using anal/vaginal probe. Motion analysis was captured by 3-dimensional motion trajectories of the retro-reflective markers. RESULTS At the ankle dorsiflexion, pelvic tilted anteriorly and PFMs were activated, but there was no pelvic movement in ankle plantar flexion. Significantly greater PFM activities were seen in ankle dorsiflexion. CONCLUSIONS PFM exercises performed in active ankle dorsiflexion positions while standing may increase the effectiveness of these exercises. For an effective pelvic floor enhancement in patients with weak PFMs, we recommend a dorsiflexion of the ankle in the standing position. PMID- 30301877 TI - Loss of TNFAIP3 enhances MYD88L265P-driven signaling in non-Hodgkin lymphoma. AB - MYD88 mutations are one of the most recurrent mutations in hematologic malignancies. However, recent mouse models suggest that MYD88L265P alone may not be sufficient to induce tumor formation. Interplay between MYD88L265P and other genetic events is further supported by the fact that TNFAIP3 (A20) inactivation often accompanies MYD88L265P. However, we are still lacking information about the consequence of MYD88L265P in combination with TNFAIP3 loss in human B cell lymphoma. Review of our genetic data on diffuse large B cell lymphoma (DLBCL) and Waldenstrom macroglobulinemia (WM), found that a large percentage of DLBCL and WM cases that have a MYD88 mutation also harbor a TNFAIP3 loss, 55% DLBCL and 28% of WM, respectively. To mimic this combination of genetic events, we used genomic editing technology to knock out TNFAIP3 in MYD88L265P non-Hodgkin's lymphoma (NHL) cell lines. Loss of A20 expression resulted in increased NF-kappaB and p38 activity leading to upregulation of the NF-kappaB target genes BCL2 and MYC. Furthermore, we detected the increased production of IL-6 and CXCL10 which led to an upregulation of the JAK/STAT pathway. Overall, these results suggest that MYD88L265P signaling can be enhanced by a second genetic alteration in TNFAIP3 and highlights a potential opportunity for therapeutic targeting. PMID- 30301878 TI - Circadian rhythms and psychiatric profiles in young adults with unipolar depressive disorders. AB - Abnormalities in circadian rhythms have been reported in people with mood disorders, but these abnormalities are marked by considerable inter-individual variability. This study aimed to identify pathophysiological subgroups on the basis of circadian markers and evaluate how these subgroups relate to psychiatric profiles. Thirty-five young adults (18-31 years old) receiving clinical care for unipolar depressive disorders and 15 healthy controls took part to this study. The Hamilton Rating Scale for Depression and the Young Mania rating scale were used to evaluate the severity of mood symptoms in participants with depressive disorders. All participant underwent ambulatory sleep monitoring with actigraphy for about 12 days before attending a laboratory-based chronobiological assessment which included repeated salivary samples to determine dim light melatonin onset (DLMO) and continuous core body temperature (CBT) monitoring using an ingestible temperature sensor. Cluster analyses were conducted across all participants to identify subgroups with consistent circadian timing profiles based on DLMO and the nocturnal minima of CBT. Two clusters were identified: 'delayed' and 'conventional timing' circadian phase. Descriptive analyses showed that the delayed cluster was characterised by abnormal time relationships between circadian phase markers and the sleep-wake cycle. Importantly, individuals from the delayed cluster had worse depression severity (t(28) = -2.7, p = 0.011) and hypomanic symptoms (Z = -2.2, p = 0.041) than their peers with conventional circadian timing. These findings suggest that delayed and disorganised circadian rhythms may be linked to worse psychiatric profiles in young people with depressive disorders. PMID- 30301879 TI - Schizophrenia-related cognitive dysfunction in the Cyclin-D2 knockout mouse model of ventral hippocampal hyperactivity. AB - Elevated activity at the output stage of the anterior hippocampus has been described as a physiological endophenotype of schizophrenia, and its development maps onto the transition from the prodromal to the psychotic state. Interventions that halt the spreading glutamatergic over-activity in this region and thereby the development of overt schizophrenia could be promising therapies. However, animal models with high construct validity to support such pre-clinical development are scarce. The Cyclin-D2 knockout (CD2-KO) mouse model shows a hippocampal parvalbumin-interneuron dysfunction, and its pattern of hippocampal over-activity shares similarities with that seen in prodromal patients. Conducting a comprehensive phenotyping of CD2-KO mice, we found that they displayed novelty-induced hyperlocomotion (a rodent correlate of positive symptoms of schizophrenia), that was largely resistant against D1- and D2 dopamine-receptor antagonism, but responsive to the mGluR2/3-agonist LY379268. In the negative symptom domain, CD2-KO mice showed transiently reduced sucrose preference (anhedonia), but enhanced interaction with novel mice and objects, as well as normal nest building and incentive motivation. Also, unconditioned anxiety, perseveration, and motor-impulsivity were unaltered. However, in the cognitive domain, CD2-knockouts showed reduced executive function in assays of rule-shift and rule-reversal learning, and also an impairment in working memory, that was resistant against LY379268-treatment. In contrast, sustained attention and forms of spatial and object-related memory that are mediated by short-term habituation of stimulus-specific attention were intact. Our results suggest that CD2-KO mice are a valuable model in translational research targeted at the pharmacoresistant cognitive symptom domain in causal relation to hippocampal over activity in the prodrome-to-psychosis transition. PMID- 30301880 TI - Dengue virus and the host innate immune response. AB - Dengue virus (DENV) is a mosquito-borne Flavivirus that is endemic in many tropical and sub-tropical countries where the transmission vectors Aedes spp. mosquitoes resides. There are four serotypes of the virus. Each serotype is antigenically different, meaning they elicit heterologous antibodies. Infection with one serotype will create neutralizing antibodies to the serotype. Cross protection from other serotypes is not long term, instead heterotypic infection can cause severe disease. This review will focus on the innate immune response to DENV infection and the virus evasion of the innate immune system by escaping recognition or inhibiting the production of an antiviral state. Activated innate immune pathways includes type I interferon, complement, apoptosis, and autophagy, which the virus can evade or exploit to exacerbate disease. It is important to understand out how the immune system reacts to infection and how the virus evades immune response in order to develop effective antivirals and vaccines. PMID- 30301881 TI - Apatinib-induced protective autophagy and apoptosis through the AKT-mTOR pathway in anaplastic thyroid cancer. AB - Apatinib, an inhibitor of vascular endothelial growth factor receptor-2, has been shown to promote anti-cancer action across a wide range of malignancies, including gastric, lung, and breast cancers. Our previous study showed that apatinib increases apoptosis in anaplastic thyroid carcinoma (ATC), but the direct functional mechanism of tumor lethality mediated by apatinib is still unknown. In this study, we demonstrated that apatinib induced both autophagy and apoptosis in human ATC cells through downregulation of p-AKT and p-mTOR signals via the AKT/mTOR pathway. Moreover, inhibition of apatinib-induced autophagy increased apatinib-induced apoptosis in ATC cells, and additional tumor suppression was critically produced by the combination of apatinib and the autophagy inhibitor chloroquine in vivo and in vitro. These findings showed that both autophagy and AKT/mTOR signals were engaged in ATC cell death evoked by apatinib. ATC patients might benefit from the new anti-cancer drug, and molecular targeted treatment in combination with autophagy inhibitors shows promise as a treatment improvement. PMID- 30301882 TI - Role of apurinic/apyrimidinic nucleases in the regulation of homologous recombination in myeloma: mechanisms and translational significance. AB - We have previously reported that homologous recombination (HR) is dysregulated in multiple myeloma (MM) and contributes to genomic instability and development of drug resistance. We now demonstrate that base excision repair (BER) associated apurinic/apyrimidinic (AP) nucleases (APEX1 and APEX2) contribute to regulation of HR in MM cells. Transgenic as well as chemical inhibition of APEX1 and/or APEX2 inhibits HR activity in MM cells, whereas the overexpression of either nuclease in normal human cells, increases HR activity. Regulation of HR by AP nucleases could be attributed, at least in part, to their ability to regulate recombinase (RAD51) expression. We also show that both nucleases interact with major HR regulators and that APEX1 is involved in P73-mediated regulation of RAD51 expression in MM cells. Consistent with the role in HR, we also show that AP-knockdown or treatment with inhibitor of AP nuclease activity increases sensitivity of MM cells to melphalan and PARP inhibitor. Importantly, although inhibition of AP nuclease activity increases cytotoxicity, it reduces genomic instability caused by melphalan. In summary, we show that APEX1 and APEX2, major BER proteins, also contribute to regulation of HR in MM. These data provide basis for potential use of AP nuclease inhibitors in combination with chemotherapeutics such as melphalan for synergistic cytotoxicity in MM. PMID- 30301883 TI - Mitochondrial fusion and Bid-mediated mitochondrial apoptosis are perturbed by alcohol with distinct dependence on its metabolism. AB - Environmental stressors like ethanol (EtOH) commonly target mitochondria to influence the cell's fate. Recent literature supports that chronic EtOH exposure suppresses mitochondrial dynamics, central to quality control, and sensitizes mitochondrial permeability transition pore opening to promote cell death. EtOH induced tissue injury is primarily attributed to its toxic metabolic products but alcoholism also impairs tissues that poorly metabolize EtOH. We embarked on studies to determine the respective roles of EtOH and its metabolites in mitochondrial fusion and tBid-induced mitochondrial apoptosis. We used HepG2 cells that do not metabolize EtOH and its engineered clone that expresses EtOH metabolizing Cytochrome P450 E2 and alcohol dehydrogenase (VL-17A cells). We found that fusion impairment by prolonged EtOH exposure was prominent in VL-17A cells, probably owing to reactive oxygen species increase in the mitochondrial matrix. There was no change in fusion protein abundance, mitochondrial membrane potential or Ca2+ uptake. By contrast, prolonged EtOH exposure promoted tBid induced outer mitochondrial membrane permeabilization and cell death only in HepG2 cells, owing to enhanced Bak oligomerization. Thus, mitochondrial fusion inhibition by EtOH is dependent on its metabolites, whereas sensitization to tBid induced death is mediated by EtOH itself. This difference is of pathophysiological relevance because of the tissue-specific differences in EtOH metabolism. PMID- 30301884 TI - Patchwork of contrasting medication cultures across the USA. AB - Health in the United States is markedly heterogeneous, with large disparities in disease incidence, treatment choices and health spending. Drug prescription is one major component of health care-reflecting the accuracy of diagnosis, the adherence to evidence-based guidelines, susceptibility to drug marketing and regulatory factors. Using medical claims data covering nearly half of the USA population, we have developed and validated a framework to compare prescription rates of 600 popular drugs in 2334 counties. Our approach uncovers geographically separated sub-Americas, where patients receive treatment for different diseases, and where physicians choose different drugs for the same disease. The geographical variation suggests influences of racial composition, state-level health care laws and wealth. Some regions consistently prefer more expensive drugs, even when they have not been proven more efficacious than cheaper alternatives. Our study underlines the benefit of aggregating massive information on medical practice into a summarized and actionable form. PMID- 30301885 TI - Metastatic adrenocortical carcinoma displays higher mutation rate and tumor heterogeneity than primary tumors. AB - Adrenocortical cancer (ACC) is a rare cancer with poor prognosis and high mortality due to metastatic disease. All reported genetic alterations have been in primary ACC, and it is unknown if there is molecular heterogeneity in ACC. Here, we report the genetic changes associated with metastatic ACC compared to primary ACCs and tumor heterogeneity. We performed whole-exome sequencing of 33 metastatic tumors. The overall mutation rate (per megabase) in metastatic tumors was 2.8-fold higher than primary ACC tumor samples. We found tumor heterogeneity among different metastatic sites in ACC and discovered recurrent mutations in several novel genes. We observed 37-57% overlap in genes that are mutated among different metastatic sites within the same patient. We also identified new therapeutic targets in recurrent and metastatic ACC not previously described in primary ACCs. PMID- 30301886 TI - Alpha-fetoprotein inhibits autophagy to promote malignant behaviour in hepatocellular carcinoma cells by activating PI3K/AKT/mTOR signalling. AB - Alpha-fetoprotein (AFP) has been recognized as a key regulator of cell proliferation in hepatocellular carcinoma (HCC). However, whether AFP functions in cancer cell autophagy remains unknown. This study investigated the effects of AFP on autophagy in HCC cells. The role of AFP was studied in two HCC cell lines, PLC/PRF/5 and HLE. Cell autophagy, apoptosis, proliferation, migration and invasion were analysed with Western blotting, co-immunoprecipitation (CoIP), immunofluorescence, animal models, MTT assays, flow cytometry (FCM), Cell Counting Kit (CCK)-8, and scratch and transwell assays. In PLC/PRF/5 cells, AFP interacted with PTEN and activated PI3K/Akt/mTOR signalling. In HLE cells, overexpressed AFP similarly interacted with PTEN, leading to PI3K/Akt/mTOR activation and reduced cell autophagy. When AFP was silenced in PLC/PRF/5 cells, cell proliferation, tumour growth, migration and invasion were inhibited, and the numbers of S-phase and apoptotic cells were increased. In contrast, AFP overexpression in HLE cells enhanced cell proliferation, migration and invasion and reduced apoptosis. AFP-dependent autophagy, proliferation, migration and apoptosis were inhibited by rapamycin. In summary, AFP plays critical roles in the inhibition of autophagy and apoptosis in HCC cells and promotes proliferation, migration and invasion. The role of AFP in autophagy inhibition in HCC cells may involve the activation of PI3K/Akt/mTOR signalling. PMID- 30301889 TI - Primary care cohort study in the sequence of diagnosing chronic respiratory diseases and prescribing inhaled corticosteroids. AB - To prevent unnecessary use of inhaled corticosteroids (ICS), ICS treatment should only be started when the diagnostic process of asthma and COPD is completed. Little is known about the chronological order between these diagnoses and the start of ICS. We performed a retrospective cohort study, based on electronic medical records of 178 Dutch general practices, to explore the temporal relations between starting continuous use of ICS and receiving a diagnosis of asthma and/or COPD. The database included information of patients who were registered with a diagnosis of asthma and/or COPD in one of the practices during January 1, 2012 and December 31, 2013. Two or more successive prescriptions of ICS within 6 months were considered as continuous ICS treatment. The chronological order of events based on available dates were analysed using descriptive analyses. For 8507 patients with asthma, 4024 patients with COPD, and 801 patients with asthma COPD overlap (ACO), the order of events could be analysed. In total, 1857 (14.4%) patients started ICS prior to their diagnosis, 11.5, 20.8, and 10.0% of patients with asthma, COPD, and ACO, respectively. In 53.4% of the patients, the first prescription of ICS was a combination inhaler with a long-acting bronchodilator. In this real-life primary care cohort, one in seven patients started ICS treatment prior to their diagnosis and approximately half of the patients started with a combination inhaler. Our findings suggest that there is relevant room for improvement in the pharmaceutical management of patients with these chronic respiratory diseases.

AB - Despite their inherent proximity to circulating oxygen and nutrients, endothelial cells (ECs) oxidize only a minor fraction of glucose in mitochondria, a metabolic specialization that is poorly understood. Here we show that the glycolytic enzyme pyruvate kinase M2 (PKM2) limits glucose oxidation, and maintains the growth and epigenetic state of ECs. We find that loss of PKM2 alters mitochondrial substrate utilization and impairs EC proliferation and migration in vivo. Mechanistically, we show that the NF-kappaB transcription factor RELB is responsive to PKM2 loss, limiting EC growth through the regulation of P53. Furthermore, S adenosylmethionine synthesis is impaired in the absence of PKM2, resulting in DNA hypomethylation, de-repression of endogenous retroviral elements (ERVs) and activation of antiviral innate immune signalling. This work reveals the metabolic and functional consequences of glucose oxidation in the endothelium, highlights the importance of PKM2 for endothelial growth and links metabolic dysfunction with autoimmune activation in ECs.

The current consensus is that cerebral organoids consist of cells derived from the neuroectodermal lineage. This limits their value and applicability, as mesodermal-derived microglia are important players in neural development and disease. Remarkably, here we show that microglia can innately develop within a cerebral organoid model and display their characteristic ramified morphology. The transcriptome and response to inflammatory stimulation of these organoid-grown microglia closely mimic the transcriptome and response of adult microglia acutely isolated from post mortem human brain tissue. In addition, organoid-grown microglia mediate phagocytosis and synaptic material is detected inside them. In all, our study characterizes a microglia-containing organoid model that represents a valuable tool for studying the interplay between microglia, macroglia, and neurons in human brain development and disease. PMID- 30301890 TI - Physical descriptor for the Gibbs energy of inorganic crystalline solids and temperature-dependent materials chemistry. AB - The Gibbs energy, G, determines the equilibrium conditions of chemical reactions and materials stability. Despite this fundamental and ubiquitous role, G has been tabulated for only a small fraction of known inorganic compounds, impeding a comprehensive perspective on the effects of temperature and composition on materials stability and synthesizability. Here, we use the SISSO (sure independence screening and sparsifying operator) approach to identify a simple and accurate descriptor to predict G for stoichiometric inorganic compounds with ~50 meV atom-1 (~1 kcal mol-1) resolution, and with minimal computational cost, for temperatures ranging from 300-1800 K. We then apply this descriptor to ~30,000 known materials curated from the Inorganic Crystal Structure Database (ICSD). Using the resulting predicted thermochemical data, we generate thousands of temperature-dependent phase diagrams to provide insights into the effects of temperature and composition on materials synthesizability and stability and to establish the temperature-dependent scale of metastability for inorganic compounds. PMID- 30301892 TI - Interface-mediated hygroelectric generator with an output voltage approaching 1.5 volts. AB - Hygroelectricity is proposed as a means to produce electric power from air by absorbing gaseous or vaporous water molecules, which are ubiquitous in the atmosphere. Here, using a synergy between a hygroscopic bulk graphene oxide with a heterogeneous structure and interface mediation between electrodes/materials with Schottky junctions, we develop a high-performance hygroelectric generator unit with an output voltage approaching 1.5 V. High voltage (e.g., 18 V with 15 units) can be easily reached by simply scaling up the number of hygroelectric generator units in series, enough to drive commercial electronic devices. This work provides insight for the design and development of hygroelectric generators that may promote the efficient conversion of potential energy in the environmental atmosphere to electricity for practical applications. PMID- 30301891 TI - A genetic network mediating the control of bud break in hybrid aspen. AB - In boreal and temperate ecosystems, temperature signal regulates the reactivation of growth (bud break) in perennials in the spring. Molecular basis of temperature mediated control of bud break is poorly understood. Here we identify a genetic network mediating the control of bud break in hybrid aspen. The key components of this network are transcription factor SHORT VEGETATIVE PHASE-LIKE (SVL), closely related to Arabidopsis floral repressor SHORT VEGETATIVE PHASE, and its downstream target TCP18, a tree homolog of a branching regulator in Arabidopsis. SVL and TCP18 are downregulated by low temperature. Genetic evidence demonstrates their role as negative regulators of bud break. SVL mediates bud break by antagonistically acting on gibberellic acid (GA) and abscisic acid (ABA) pathways, which function as positive and negative regulators of bud break, respectively. Thus, our results reveal the mechanistic basis for temperature-cued seasonal control of a key phenological event in perennial plants. PMID- 30301893 TI - Meta-analysis of effects of exclusive breastfeeding on infant gut microbiota across populations. AB - Previous studies on the differences in gut microbiota between exclusively breastfed (EBF) and non-EBF infants have provided highly variable results. Here we perform a meta-analysis of seven microbiome studies (1825 stool samples from 684 infants) to compare the gut microbiota of non-EBF and EBF infants across populations. In the first 6 months of life, gut bacterial diversity, microbiota age, relative abundances of Bacteroidetes and Firmicutes, and predicted microbial pathways related to carbohydrate metabolism are consistently higher in non-EBF than in EBF infants, whereas relative abundances of pathways related to lipid metabolism, vitamin metabolism, and detoxification are lower. Variation in predicted microbial pathways associated with non-EBF infants is larger among infants born by Caesarian section than among those vaginally delivered. Longer duration of exclusive breastfeeding is associated with reduced diarrhea-related gut microbiota dysbiosis. Furthermore, differences in gut microbiota between EBF and non-EBF infants persist after 6 months of age. Our findings elucidate some mechanisms of short and long-term benefits of exclusive breastfeeding across different populations. PMID- 30301894 TI - Stabilizing black phosphorus nanosheets via edge-selective bonding of sacrificial C60 molecules. AB - Few-layer black phosphorus (BP) with an anisotropic two-dimensional (2D)-layered structure shows potential applications in photoelectric conversion and photocatalysis, but is easily oxidized under ambient condition preferentially at its edge sites. Improving the ambient stability of BP nanosheets has been fulfilled by chemical functionalization, however this functionalization is typically non-selective. Here we show that edge-selective functionalization of BP nanosheets by covalently bonding stable C60 molecules leads to its significant stability improvement. Owing to the high stability of the hydrophobic C60 molecule, C60 functions as a sacrificial shield and effectively protects BP nanosheets from oxidation under ambient condition. C60 bonding leads to a rapid photoinduced electron transfer from BP to C60, affording enhanced photoelectrochemical and photocatalytic activities. The selective passivation of the reactive edge sites of BP nanosheets by sacrificial C60 molecules paves the way toward ambient processing and applications of BP. PMID- 30301896 TI - Unravelling the structure of glycosyl cations via cold-ion infrared spectroscopy. AB - Glycosyl cations are the key intermediates during the glycosylation reaction that covalently links building blocks during the synthetic assembly of carbohydrates. The exact structure of these ions remained elusive due to their transient and short-lived nature. Structural insights into the intermediate would improve our understanding of the reaction mechanism of glycosidic bond formation. Here, we report an in-depth structural analysis of glycosyl cations using a combination of cold-ion infrared spectroscopy and first-principles theory. Participating C2 protective groups form indeed a covalent bond with the anomeric carbon that leads to C1-bridged acetoxonium-type structures. The resulting bicyclic structure strongly distorts the ring, which leads to a unique conformation for each individual monosaccharide. This gain in mechanistic understanding fundamentally impacts glycosynthesis and will allow to tailor building blocks and reaction conditions in the future. PMID- 30301895 TI - Genetic signature to provide robust risk assessment of psoriatic arthritis development in psoriasis patients. AB - Psoriatic arthritis (PsA) is a complex chronic musculoskeletal condition that occurs in ~30% of psoriasis patients. Currently, no systematic strategy is available that utilizes the differences in genetic architecture between PsA and cutaneous-only psoriasis (PsC) to assess PsA risk before symptoms appear. Here, we introduce a computational pipeline for predicting PsA among psoriasis patients using data from six cohorts with >7000 genotyped PsA and PsC patients. We identify 9 new loci for psoriasis or its subtypes and achieve 0.82 area under the receiver operator curve in distinguishing PsA vs. PsC when using 200 genetic markers. Among the top 5% of our PsA prediction we achieve >90% precision with 100% specificity and 16% recall for predicting PsA among psoriatic patients, using conditional inference forest or shrinkage discriminant analysis. Combining statistical and machine-learning techniques, we show that the underlying genetic differences between psoriasis subtypes can be used for individualized subtype risk assessment. PMID- 30301897 TI - Two-site H2O2 photo-oxidation on haematite photoanodes. AB - H2O2 is a sacrificial reductant that is often used as a hole scavenger to gain insight into photoanode properties. Here we show a distinct mechanism of H2O2 photo-oxidation on haematite (alpha-Fe2O3) photoanodes. We found that the photocurrent voltammograms display non-monotonous behaviour upon varying the H2O2 concentration, which is not in accord with a linear surface reaction mechanism that involves a single reaction site as in Eley-Rideal reactions. We postulate a nonlinear kinetic mechanism that involves concerted interaction between adions induced by H2O2 deprotonation in the alkaline solution with adjacent intermediate species of the water photo-oxidation reaction, thereby involving two reaction sites as in Langmuir-Hinshelwood reactions. The devised kinetic model reproduces our main observations and predicts coexistence of two surface reaction paths (bi stability) in a certain range of potentials and H2O2 concentrations. This prediction is confirmed experimentally by observing a hysteresis loop in the photocurrent voltammogram measured in the predicted coexistence range. PMID- 30301898 TI - Cryo-EM structure of the hibernating Thermus thermophilus 100S ribosome reveals a protein-mediated dimerization mechanism. AB - In response to cellular stresses bacteria conserve energy by dimerization of ribosomes into inactive hibernating 100S ribosome particles. Ribosome dimerization in Thermus thermophilus is facilitated by hibernation-promoting factor (TtHPF). In this study we demonstrate high sensitivity of Tt100S formation to the levels of TtHPF and show that a 1:1 ratio leads to optimal dimerization. We report structures of the T. thermophilus 100S ribosome determined by cryo electron microscopy to average resolutions of 4.13 A and 4.57 A. In addition, we present a 3.28 A high-resolution cryo-EM reconstruction of a 70S ribosome from a hibernating ribosome dimer and reveal a role for the linker region connecting the TtHPF N- and C-terminal domains in translation inhibition by preventing Shine Dalgarno duplex formation. Our work demonstrates that species-specific differences in the dimerization interface govern the overall conformation of the 100S ribosome particle and that for Thermus thermophilus no ribosome-ribosome interactions are involved in the interface. PMID- 30301899 TI - A hippocampal circuit linking dorsal CA2 to ventral CA1 critical for social memory dynamics. AB - Recent results suggest that social memory requires the dorsal hippocampal CA2 region as well as a subset of ventral CA1 neurons. However, it is unclear whether dorsal CA2 and ventral CA1 represent parallel or sequential circuits. Moreover, because evidence implicating CA2 in social memory comes largely from long-term inactivation experiments, the dynamic role of CA2 in social memory remains unclear. Here, we use pharmacogenetics and optogenetics in mice to acutely and reversibly silence dorsal CA2 and its projections to ventral hippocampus. We show that dorsal CA2 activity is critical for encoding, consolidation, and recall phases of social memory. Moreover, dorsal CA2 contributes to social memory by providing strong excitatory input to the same subregion of ventral CA1 that contains the subset of neurons implicated in social memory. Thus, our studies provide new insights into a dorsal CA2 to ventral CA1 circuit whose dynamic activity is necessary for social memory. PMID- 30301900 TI - Understanding the transfer reaction network behind the non-processive synthesis of low molecular weight levan catalyzed by Bacillus subtilis levansucrase. AB - Under specific reaction conditions, levansucrase from Bacillus subtilis (SacB) catalyzes the synthesis of a low molecular weight levan through the non processive elongation of a great number of intermediates. To deepen understanding of the polymer elongation mechanism, we conducted a meticulous examination of the fructooligosaccharide profile evolution during the levan synthesis. As a result, the formation of primary and secondary intermediates series in different reaction stages was observed. The origin of the series was identified through comparison with product profiles obtained in acceptor reactions employing levanbiose, blastose, 1-kestose, 6-kestose, and neo-kestose, and supported with the isolation and NMR analyses of some relevant products, demonstrating that all of them are inherent products during levan formation from sucrose. These results allowed to establish the network of fructosyl transfer reactions involved in the non processive levan synthesis. Overall, our results reveal how the relaxed acceptor specificity of SacB during the initial steps of the synthesis is responsible for the formation of several levan series, which constitute the final low molecular weight levan distribution. PMID- 30301901 TI - A Pre-Clinical Large Animal Model of Sustained Liver Injury and Regeneration Stimulus. AB - A feasible large animal model to evaluate regenerative medicine techniques is vital for developing clinical applications. One such appropriate model could be to use retrorsine (RS) together with partial hepatectomy (PH). Here, we have developed the first porcine model using RS and PH. RS or saline control was administered intraperitoneally to Gottingen miniature pigs twice, two weeks apart. Four weeks after the second dose, animals underwent PH. Initially, we tested different doses of RS and resection of different amounts of liver, and selected 50 mg/kg RS with 60% hepatectomy as our model for further testing. Treated animals were sacrificed 3, 10, 17 or 28 days after PH. Blood samples and resected liver were collected. Serum and liver RS content was determined by Liquid Chromatograph-tandem Mass Spectrometer. Blood analyses demonstrated liver dysfunction after PH. Liver regeneration was significantly inhibited 10 and 17 days after PH in RS-treated animals, to the extent of 20%. Histological examination indicated hepatic injury and regenerative responses after PH. Immunohistochemical staining demonstrated accumulation of Cyclin D1 and suppression of Ki-67 and PCNA in RS-treated animals. We report the development of the first large animal model of sustained liver injury with suppression of hepatic regeneration. PMID- 30301902 TI - Prevalence of the Metabolic Syndrome and its determinants among Nepalese adults: Findings from a nationally representative cross-sectional study. AB - Metabolic syndrome (MetS) increases the risk of cardiovascular diseases and diabetes mellitus. This study is designed to assess the prevalence and determinants of MetS among Nepalese adults from a nationally representative study. This study is based on Stepwise Approach to Surveillance (STEPS) Survey from Nepal. This survey was done among 4200 adults aged 15-69 years from 210 clusters selected proportionately across Nepal's three ecological zones (Mountain, Hill and Terai). Subsequently, using systematic sampling, twenty households per cluster and one participant per household were selected. The overall prevalence of MetS is 15% and 16% according to Adult Treatment Panel III (ATP III) and International Diabetes Federation (IDF) criteria respectively. A triad of low HDL-C, abdominal obesity and high BP was the most prevalent (8.18%), followed by abdominal obesity, low HDL-C cholesterol and high triglycerides (8%). Less than two percent of participants had all the five components of the syndrome and 19% of participants had none. The prevalence steadily rose across the age group with adults aged 45-69 years having the highest prevalence (28-30%) and comparable prevalence across two definitions of MetS. A notably high burden for females, urban, hill or Terai resident were seen among other factors. PMID- 30301903 TI - Deletion of exon 4 in LAMA2 is the most frequent mutation in Chinese patients with laminin alpha2-related muscular dystrophy. AB - Although recessive mutations in LAMA2 are already known to cause laminin alpha2 related muscular dystrophy, a rare neuromuscular disorder, large deletions or duplications within this gene are not well-characterized. In this study, we applied next-generation sequencing-based copy number variation profiling in 114 individuals clinically diagnosed with laminin alpha2-related muscular dystrophy, including 96 who harboured LAMA2 mutations and 34 who harboured intragenic rearrangements. In total, we detected 18 distinct LAMA2 copy number variations that have been reported only among Chinese, 10 of which are novel. The frequency of CNVs in the cohort was 19.3%. Deletion of exon 4 was detected in 10 alleles of eight patients, accounting for 27% of all copy number variations. These patients are Han Chinese and were found to have the same haplotype and sequence at the breakpoint junction, suggesting that exon 4 deletion is a founder mutation in Chinese Han and a mutation hotspot. Moreover, the data highlight our approach, a modified next-generation sequencing assay, as a robust and sensitive tool to detect LAMA2 variants; the assay identifies 85.7% of breakpoint junctions directly alongside sequence information. The method can be applied to clinical samples to determine causal variants underlying various Mendelian disorders. PMID- 30301904 TI - Age-Related Measurements of the Myelin Water Fraction derived from 3D multi-echo GRASE reflect Myelin Content of the Cerebral White Matter. AB - Myelin Water Fraction (MWF) measurements derived from quantitative Myelin Water Imaging (MWI) may detect demyelinating changes of the cerebral white matter (WM) microstructure. Here, we investigated age-related alterations of the MWF in normal aging brains of healthy volunteers utilizing two fast and clinically feasible 3D gradient and spin echo (GRASE) MWI sequences with 3 mm and 5 mm isotropic voxel size. In 45 healthy subjects (age range: 18-79 years), distinct regions of interest (ROI) were defined in the cerebral WM including corticospinal tracts. For the 3 mm sequence, significant correlations of the mean MWF with age were found for most ROIs (r < -0.8 for WM ROIs; r = -0.55 for splenium of corpus callosum; r = -0.75 for genu of corpus callosum; p < 0.001 for all ROIs). Similar correlations with age were found for the ROIs of the 5 mm sequence. No significant correlations were found for the corticospinal tract and the occipital WM (p > 0.05). Mean MWF values obtained from the 3 mm and 5 mm sequences were strongly comparable. The applied 3D GRASE MWI sequences were found to be sensitive for age-dependent myelin changes of the cerebral WM microstructure. The reported MWF values might be of substantial use as reference for further investigations in patient studies. PMID- 30301905 TI - Higher species richness enhances yield stability in intensively managed grasslands with experimental disturbance. AB - Climate models predict increased frequency and severity of drought events. At an Irish and Swiss site, experimental summer droughts were applied over two successive years to grassland plots sown with one, two or four grassland species with contrasting functional traits. Mean yield and plot-to-plot variance of yield were measured across harvests during drought and after a subsequent post-drought recovery period. At both sites, there was a positive relationship between species richness and yield. Under rainfed control conditions, mean yields of four-species communities were 32% (Wexford, Ireland) and 51% (Zurich, Switzerland) higher than in monocultures. This positive relationship was also evident under drought, despite significant average yield reductions (-27% at Wexford; -21% at Zurich). Four-species communities had lower plot-to-plot variance of yield compared to monoculture or two-species communities under both rainfed and drought conditions, which demonstrates higher yield stability in four-species communities. At the Swiss but not the Irish site, a high degree of species asynchrony could be identified as a mechanism underlying increased temporal stability in four-species communities. These results indicate the high potential of multi-species grasslands as an adaptation strategy against drought events and help achieve sustainable intensification under both unperturbed and perturbed environmental conditions. PMID- 30301906 TI - Working Memory Training Improves Emotion Regulation Ability. AB - Emotion regulation deficits are associated with various emotional disorders. Therefore, studies have attempted to improve emotion regulation ability to prevent psychopathological symptoms. Studies have revealed that working memory training-specifically attention control-can promote emotion regulation. In the present study, participants completed a running memory task in a 20-day training period. The participants' pre- and post-test data on attention network functions and late positive potential (LPP) were assessed and analyzed. Compared with the control group, the training group's orientation function improved markedly. In addition, LPP in relation to emotion regulation decreased during the 20-day training period. These results suggest that working memory training can improve emotion regulation ability, and the orientation function in the attention network may also contribute to this improvement. PMID- 30301907 TI - CHI3L1 promotes tumor progression by activating TGF-beta signaling pathway in hepatocellular carcinoma. AB - CHI3L1 (YKL40) is a secreted glycoprotein and elevated serum CHI3L1 level has been proved to be associated with poor prognosis in many human cancers. However, the mechanism of how CHI3L1 causes poor prognosis in cancers is still unknown. Here, considering that CHI3L1 is a liver specific/enriched protein, we use hepatocellular carcinoma as a model to study the function of CHI3L1. We showed that, both in vivo and in vitro, overexpression of CHI3L1 could promote liver cancer cells growth, migration and invasion. We then used RNA-seq to analyze the expression profiles of CHI3L1 overexpressed in two HCC cell lines and found that CHI3L1 overexpression affected genes that were involved in cell-cell adhesion, extracellular exosome and adherens junction. Western blot analysis further revealed that CHI3L1 could activate TGF-beta signal pathways. Our data added new understanding of the mechanism of CHI3L1's action. 1) CHI3L1 promoted cancer cell proliferation by regulating cell cycles; 2) CHI3L1 promoted cancer cell invasion and metastasis; 3) CHI3L1 regulate liver cancer potentially by regulating the TGF beta signaling pathways; 4) CHI3L1 has direct kinase activities or activate kinase to phosphorylate SMAD2, SMAD3. PMID- 30301908 TI - Retraction Note: Hsa-miR-520d induces hepatoma cells to form normal liver tissues via a stemness-mediated process. AB - This paper has been retracted. PMID- 30301909 TI - Dual-controlled optogenetic system for the rapid down-regulation of protein levels in mammalian cells. AB - Optogenetic switches are emerging molecular tools for studying cellular processes as they offer higher spatiotemporal and quantitative precision than classical, chemical-based switches. Light-controllable gene expression systems designed to upregulate protein expression levels meanwhile show performances superior to their chemical-based counterparts. However, systems to reduce protein levels with similar efficiency are lagging behind. Here, we present a novel two-component, blue light-responsive optogenetic OFF switch ('Blue-OFF'), which enables a rapid and quantitative down-regulation of a protein upon illumination. Blue-OFF combines the first light responsive repressor KRAB-EL222 with the protein degradation module B-LID (blue light-inducible degradation domain) to simultaneously control gene expression and protein stability with a single wavelength. Blue-OFF thus outperforms current optogenetic systems for controlling protein levels. The system is described by a mathematical model which aids in the choice of experimental conditions such as light intensity and illumination regime to obtain the desired outcome. This approach represents an advancement of dual controlled optogenetic systems in which multiple photosensory modules operate synergistically. As exemplified here for the control of apoptosis in mammalian cell culture, the approach opens up novel perspectives in fundamental research and applications such as tissue engineering. PMID- 30301910 TI - A frequency reconfigurable dipole antenna with solid-state plasma in silicon. AB - A frequency reconfigurable dipole antenna based on a silicon radiator is presented. The silicon radiator is activated with the aid of highly dense solid state plasma by injecting carriers into the intrinsic region of p-i-n diodes. The fabrication and design guideline of the reconfigurable dipole antenna with this plasma radiator are described. When the plasma radiator is activated or deactivated, the length of the dipole arm changes, which means that the operating frequency of the dipole antenna is reconfigurable. When all the channels in the plasma radiator are activated, the operating frequency is tuned from 6.3 GHz to 4.9 GHz. The measured tunable bandwidth of our fabricated dipole antenna is approximately 31%, which is a practical value in comparison to conventional frequency reconfigurable antennas whose tunable bandwidth is in a range from 20% to 50%. To further support the validity of our results, we provide the well matched simulation results from an antenna simulation. These results demonstrate that silicon with its commercial technology, which has not attracted attention in comparison to a metal antennas, is a promising tunable material for a frequency reconfigurable antenna. This plasma-based reconfigurable antenna has great potential for use in the dynamic communication environment. PMID- 30301911 TI - Selection of suitable reference genes for qRT-PCR normalisation under different experimental conditions in Eucommia ulmoides Oliv. AB - Normalisation of data, by choosing the appropriate reference genes, is fundamental for obtaining reliable results in quantitative real-time PCR (qPCR). This study evaluated the expression stability of 11 candidate reference genes with different varieties, developmental periods, tissues, and abiotic stresses by using four statistical algorithms: geNorm, NormFinder, BestKeeper, and RefFinder. The results indicated that ubiquitin-conjugating enzyme S (UBC) and ubiquitin conjugating enzyme E2 (UBC E2) could be used as reference genes for different E. ulmoides varieties and tissues, UBC and histone H4 (HIS4) for different developmental periods, beta-tubulin (TUB) and UBC for cold treatment, ubiquitin extension protein (UBA80) and HIS4 for drought treatment, and ubiquitin-60S ribosomal protein L40 (UBA52) and UBC E2 for salinity treatment. UBC and UBC E2 for the group "Natural growth" and "Total", UBA80 and UBC for the group "Abiotic stresses". To validate the suitability of the selected reference genes in this study, mevalonate kinase (MK), phenylalanine ammonia-lyase (PAL), and 4-coumarate CoA ligase (4CL) gene expression patterns were analysed. When the most unstable reference genes were used for normalisation, the expression patterns had significant biases compared with the optimum reference gene combinations. These results will be beneficial for more accurate quantification of gene expression levels in E. ulmoides. PMID- 30301912 TI - Temperature-mediated invocation of the vacuum state for switchable ultrawide angle and broadband deflection. AB - Temperature-mediated appearance and disappearance of a deflection grating in a diffracting structure is possible by employing InSb as the grating material. InSb transits from the dielectric state to the plasmonic state in the terahertz regime as the temperature increases, this transition being reversible. An intermediate state is the vacuum state in which the real part of the relative permittivity of InSb equals unity while the imaginary part is much smaller. Then the grating virtually disappears, deflection being impossible as only specular reflection can occur. This ON/OFF switching of deflection and relevant angular filtering are realizable over wide ranges of frequency and incidence angle by a temperature change of as low as 20 K. The vacuum state of InSb invoked for ON/OFF switching of deflection and relevant angular filtering can also be obtained for thermally tunable materials other than InSb as well as by using non-thermal mechanisms. PMID- 30301913 TI - Positive effects of the catastrophic Hurricane Patricia on insect communities. AB - Highly seasonal conditions of tropical dry forests determine the temporal patterns of insect abundance. However, density-independent factors such as natural disturbances can abruptly change environmental conditions, affecting insect populations. We address the effects of the Hurricane Patricia (category 5) on species density and abundance of three feeding guilds of herbivorous insects (sap-sucking, folivorous beetles and xylophagous) and predatory beetles associated to the canopy of a tropical dry forest. Hurricane Patricia has been the strongest tropical hurricane ever reported in the Western Hemisphere. Herbivorous insects (sap-sucking and xylophagous) and predatory beetles increased in species density and abundance in the following months after the hurricane, compared to samples before it. The positive response of sap-sucking insects to Hurricane Patricia was probably related to an increase in the availability of new shoots and leaf meristems after the natural coppicing by the hurricane, while xylophagous guild seems to have been positively affected by the increase in the amount and diversity of deadwood resources. The positive response of predatory beetles may be the result of a bottom-up effect due to a greater availability of arthropod preys after the hurricane. We demonstrated that catastrophic hurricane disturbances could be important events that temporarily increase the species density and abundance of insects in tropical dry forests. PMID- 30301914 TI - Ultrafast polarization control by terahertz fields via pi-electron wavefunction changes in hydrogen-bonded molecular ferroelectrics. AB - Rapid polarization control by an electric field in ferroelectrics is important to realize high-frequency modulation of light, which has potential applications in optical communications. To achieve this, a key strategy is to use an electronic part of ferroelectric polarization. A hydrogen-bonded molecular ferroelectric, croconic acid, is a good candidate, since pi-electron polarization within each molecule is theoretically predicted to play a significant role in the ferroelectric-state formation, as well as the proton displacements. Here, we show that a sub-picosecond polarization modulation is possible in croconic acid using a terahertz pulse. The terahertz-pulse-pump second-harmonic-generation-probe and optical-reflectivity-probe spectroscopy reveal that the amplitude of polarization modulation reaches 10% via the electric-field-induced modifications of pi electron wavefunctions. Moreover, the measurement of electric-field-induced changes in the infrared molecular vibrational spectrum elucidates that the contribution of proton displacements to the polarization modulation is negligibly small. These results demonstrate the electronic nature of polarization in hydrogen-bonded molecular ferroelectrics. The ultrafast polarization control via pi-electron systems observed in croconic acid is expected to be possible in many other hydrogen-bonded molecular ferroelectrics and utilized for future high-speed optical-modulation devices. PMID- 30301915 TI - Functional analysis of polyketide synthase genes in the biocontrol fungus Clonostachys rosea. AB - Clonostachys rosea is a mycoparasitic fungus used for biological control of plant diseases. Its genome contains 31 genes putatively encoding for polyketide synthases (PKSs), 75% of which are arranged in biosynthetic gene clusters. Gene expression analysis during C. rosea interactions with the fungal plant pathogens Botrytis cinerea and Fusarium graminearum showed common and species-specific induction of PKS genes. Our data showed a culture media dependent correlation between PKS gene expression and degree of antagonism in C. rosea. The pks22 and pks29 genes were highly induced during fungal-fungal interactions but not during pigmentation, and gene deletion studies revealed that PKS29 was required for full antagonism against B. cinerea, and for biocontrol of fusarium foot rot on barley. Metabolite analysis revealed that Deltapks29 strains has a 50% reduced production (P = 0.001) of an unknown polyketide with molecular formula C15H28O3, while Deltapks22 strains lost the ability to produce four previously unknown polyketides named Clonorosein A-D. Clonorosein A and B were purified, their structures determined, and showed strong antifungal activity against B. cinerea and F. graminearum. These results show that PKS22 is required for production of antifungal polyketide Clonorosein A-D, and demonstrate the role of PKS29 in antagonism and biocontrol of fungal plant diseases. PMID- 30301916 TI - Toxoplasma gondii Manipulates Expression of Host Long Noncoding RNA during Intracellular Infection. AB - Long noncoding RNA (lncRNA) are non-protein-coding transcripts greater than 200 nucleotides that regulate gene expression. The field of transcriptomics is only beginning to understand the role of lncRNA in host defense. Little is known about the role of lncRNA in the response to infection by intracellular pathogens such as Toxoplasma gondii. Using a microarray, we examined the differential expression of 35,923 lncRNAs and 24,881 mRNAs in mouse bone-marrow-derived macrophages during infection with high- and low-virulence T. gondii strains. We found that 1,522 lncRNA molecules were differentially regulated during infection with the high-virulence Type I strain, versus 528 with the less-virulent Type II strain. Of these lncRNAs, 282 were co-regulated with a nearby or overlapping mRNA including approximately 60 mRNAs with immune-related functions. We validated the microarray for 4 lncRNAs and 4 mRNAs using qRT-PCR. Using deletion strains of T. gondii, we found that the secretory kinase ROP16 controls upregulation of lncRNAs Csf1-lnc and Socs2-lnc, demonstrating that the parasite directly manipulates host lncRNA expression. Given the number of regulated lncRNAs and the magnitude of the expression changes, we hypothesize that these molecules constitute both an additional regulatory layer in the host response to infection and a target for manipulation by T. gondii.

AB - The murine basic helix-loop-helix transcription (bHLH) factor mouse atonal homolog 6 (Math6) is expressed in numerous organs and supposed to be involved in several developmental processes. However, so far neither all aspects nor the molecular mechanisms of Math6 function have been explored exhaustively. To analyze the in vivo function of Math6 in detail, we generated a constitutive knockout (KO) mouse (Math6-/-) and performed an initial histological and molecular biological investigation of its main phenotype. Pregnant Math6-/- females suffer from a disturbed early placental development leading to the death of the majority of embryos independent of the embryonic Math6 genotype. A few placentas and fetuses survive the severe uterine hemorrhagic events at late mid gestation (E13.5) and subsequently develop regularly. However, these fetuses could not be born due to obstructions within the gravid uterus, which hinder the birth process. Characterization of the endogenous spatiotemporal Math6 expression during placenta development reveals that Math6 is essential for an ordered decidualization and an important regulator of the maternal-fetal endocrine crosstalk regulating endometrial trophoblast invasion and differentiation. The strongly disturbed vascularization observed in the maternal placenta appears as an additional consequence of the altered endocrine status and as the main cause for the general hemorrhagic crisis.

AB - Flavin-binding fluorescent proteins (FPs) are genetically encoded in vivo reporters, which are derived from microbial and plant LOV photoreceptors. In this study, we comparatively analyzed ROS formation and light-driven antimicrobial efficacy of eleven LOV-based FPs. In particular, we determined singlet oxygen (1O2) quantum yields and superoxide photosensitization activities via spectroscopic assays and performed cell toxicity experiments in E. coli. Besides miniSOG and SOPP, which have been engineered to generate 1O2, all of the other tested flavoproteins were able to produce singlet oxygen and/or hydrogen peroxide but exhibited remarkable differences in ROS selectivity and yield. Accordingly, most LOV-FPs are potent photosensitizers, which can be used for light-controlled killing of bacteria. Furthermore, the two variants Pp2FbFP and DsFbFP M49I, exhibiting preferential photosensitization of singlet oxygen or singlet oxygen and superoxide, respectively, were shown to be new tools for studying specific ROS-induced cell signaling processes. The tested LOV-FPs thus further expand the toolbox of optogenetic sensitizers usable for a broad spectrum of microbiological and biomedical applications.

AB - ATP is an essential constitutive regulator of cardiac ryanodine receptors (RyR2), enabling small changes in cytosolic Ca2+ to trigger large changes in channel activity. With recent landmark determinations of the full structures of RyR1 (skeletal isoform) and RyR2 using cryo-EM, and identification of the RyR1 ATP binding site, we have taken the opportunity to model the binding of fragments of ATP into RyR2 in order to investigate how the structure of the ATP site dictates the functional responses of ligands attracted there. RyR2 channel gating was assessed under voltage-clamp conditions and by [3H]ryanodine binding studies. We show that even the triphosphate (PPPi) moiety alone was capable of activating RyR2 but produced two distinct effects (activation or irreversible inactivation) that we suggest correspond to two preferred binding locations within the ATP site. Combinations of complementary fragments of ATP (Pi + ADP or PPi + AMP) could not reproduce the effects of ATP, however, the presence of adenosine prevented the inactivating PPPi effects, allowing activation similar to that of ATP. RyR2 appears to accommodate diverse types of molecules, including PPPi, deep within the ATP binding site. The most effective ligands, however, have at least three phosphate groups that are guided into place by a nucleoside. PMID- 30301921 TI - Comparison Of Four Dietary Scores As Determinants Of Coronary Heart Disease Mortality. AB - We aimed at comparing 2 a-priori -Mediterranean Adequacy Index (MAI), the Median Score (MED) - versus 2 a-posteriori, -Factor Analysis (FA2) and Principal Components analysis (PC2)- dietary scores in 1214 CHD-free men aged 45-64 belonging to the Italian Rural Areas of the Seven Countries Study examined in 1965 and followed-up for mortality during 40 years. CHD death was the end-point. Collection of dietary history allowed to define 17 main food groups expressed in gr/day and to compare dietary scores, each divided into 3 classes. Kaplan-Meier curves showed higher survival for classes 2 and 3 (healthy) versus class 1 (unhealthy), but the log-rank test was not significant for the 2 a-priori scores. Cox proportional hazards models showed similar significant findings comparing class 3 with class 1 in the a-posteriori scores FA2 and PC2, with hazards ratios of 0.48 and 0.43, that became 0.65 and 0.53 respectively after adjusting for six specific risk factors for CHD (age, cigarette smoking, systolic blood pressure, serum cholesterol, body mass index and physical activity). Food intake of class 3 in all 4 scores matched rather well the characteristics of the Mediterranean Diet. The poor performance of a-priori dietary scores was partly explained by the unexpected and direct relationship of fruit intake with CHD deaths. The superiority of a-posteriori dietary patterns could be in turn due to the specificity of the study population. External validations and comparisons of a priori versus a-posteriori dietary patterns in larger cohorts, using the same 17 food groups explored here, are urgently needed. PMID- 30301920 TI - Overlapping motifs on the herpes viral proteins ICP27 and ORF57 mediate interactions with the mRNA export adaptors ALYREF and UIF. AB - The TREX complex mediates the passage of bulk cellular mRNA export to the nuclear export factor TAP/NXF1 via the export adaptors ALYREF or UIF, which appear to act in a redundant manner. TREX complex recruitment to nascent RNA is coupled with 5' capping, splicing and polyadenylation. Therefore to facilitate expression from their intronless genes, herpes viruses have evolved a mechanism to circumvent these cellular controls. Central to this process is a protein from the conserved ICP27 family, which binds viral transcripts and cellular TREX complex components including ALYREF. Here we have identified a novel interaction between HSV-1 ICP27 and an N-terminal domain of UIF in vivo, and used NMR spectroscopy to locate the UIF binding site within an intrinsically disordered region of ICP27. We also characterized the interaction sites of the ICP27 homolog ORF57 from KSHV with UIF and ALYREF using NMR, revealing previously unidentified binding motifs. In both ORF57 and ICP27 the interaction sites for ALYREF and UIF partially overlap, suggestive of mutually exclusive binding. The data provide a map of the binding sites responsible for promoting herpes virus mRNA export, enabling future studies to accurately probe these interactions and reveal the functional consequences for UIF and ALYREF redundancy.

AB - This study aims to detect high grade squamous intraepithelial cells (HSIL) by investigating HSIL associated biochemical changes in morphologically normal appearing intermediate and superficial cells using Raman spectroscopy. Raman spectra (n = 755) were measured from intermediate and superficial cells from negative cytology ThinPrep specimens (n = 18) and from morphologically normal appearing intermediate and superficial cells from HSIL cytology ThinPrep specimens (n = 17). The Raman data was subjected to multivariate algorithms including the standard principal component analysis (PCA)-linear discriminant analysis (LDA) and partial least squares discriminant analysis (PLS-DA) together with random subsets cross-validation for discriminating negative cytology from HSIL. The PCA-LDA method yielded sensitivities of 74.9%, 72.8%, and 75.6% and specificities of 89.9%, 81.9%, and 84.5%, for HSIL diagnosis based on the dataset obtained from intermediate, superficial and mixed intermediate/superficial cells, respectively. The PLS-DA method provided improved sensitivities of 95.5%, 95.2% and 96.1% and specificities of 92.7%, 94.7% and 93.5% compared to the PCA-LDA method. The results demonstrate that the biochemical signatures of morphologically normal appearing cells can be used to discriminate between negative and HSIL cytology. In addition, it was found that mixed intermediate and superficial cells could be used for HSIL diagnosis as the biochemical differences between negative and HSIL cytology were greater than the biochemical differences between intermediate and superficial cell types. PMID- 30301923 TI - Genetic variations in TAS2R3 and TAS2R4 bitterness receptors modify papillary carcinoma risk and thyroid function in Korean females. AB - Type 2 taste receptors (T2Rs, TAS2Rs) mediate bitterness perception and are involved in diverse defence mechanisms in extraoral tissues. The thyrocyte expressed T2Rs control thyroid hormone production, and this regulatory role may be associated with susceptibility to thyroid diseases. This study examined whether the variations in TAS2Rs modify the risk of papillary thyroid carcinoma (PTC) and whether such T2R-related PTC risk is associated with genetically modified thyroid function. We conducted a case-control study with 763 Korean females, including 250 PTC cases. Seventy-three single-nucleotide polymorphisms in 13 TAS2R genes and the pre-diagnosis levels of 4 thyroid-related functional markers [total triiodothyronine (TT3), free thyroxine, thyroid-stimulating hormone and thyroglobulin] were analysed. Individuals with TAS2R3/4 CC haplotype (rs2270009 and rs2234001) were at a lower risk for PTC than those with the remaining haplotypes (odds ratio = 0.59, 95% confidence interval: 0.36-0.97). Furthermore, TT3 levels were significantly reduced for TAS2R3/4 CC haplotype carriers compared with other haplotype carriers (p = 0.005). No other genetic variants exhibited critical associations with the PTC phenotype and biomarkers. In summary, genetic variations in T2R3/4 bitterness receptors may modify the PTC risk, and the genetically modified thyroid hormone level by those variations may be linked with the PTC-T2Rs association. PMID- 30301925 TI - Multiplex Biomarker Screening Assay for Urinary Extracellular Vesicles Study: A Targeted Label-Free Proteomic Approach. AB - The recent advance in targeted label-free proteomics, SWATH-MS, can provide consistent protein detection and reproducible protein quantitation, which is a considerable advantage for biomarker study of urinary extracellular vesicles. We developed a SWATH-MS workflow with a curated spectral library of 1,145 targets. Application of the workflow across nine replicates of three sample types (exosome like vesicles (ELVs), microvesicles (MVs) and urine proteins (UPs)) resulted in the quantitation of 888 proteins at FDR <1%. The median-coefficient of variation of the 888 proteins in the ELV sample was 7.7%, indicating excellent reproducibility. Data analysis showed common exosome markers, (i.e. CD9, CD63, ALIX, TSG101 and HSP70) were enriched in urinary ELVs as compared to MVs and UPs. The use of a multiplex biomarker screening assay focused on ELVs was investigated, and perspectives in future applications are discussed. PMID- 30301924 TI - Viable Mice with Extensive Gene Humanization (25-kbp) Created Using Embryonic Stem Cell/Blastocyst and CRISPR/Zygote Injection Approaches. AB - Here, we describe an expansion of the typical DNA size limitations associated with CRISPR knock-in technology, more specifically, the physical extent to which mouse genomic DNA can be replaced with donor (in this case, human) DNA at an orthologous locus by zygotic injection. Driving our efforts was the desire to create a whole animal model that would replace 17 kilobase pairs (kbp) of the mouse Bcl2l11 gene with the corresponding 25-kbp segment of human BCL2L11, including a conditionally removable segment (2.9-kbp) of intron 2, a cryptic human exon immediately 3' of this, and a native human exon some 20 kbp downstream. Using two methods, we first carried out the replacement by employing a combination of bacterial artificial chromosome recombineering, classic embryonic stem cell (ESC) targeting, dual selection, and recombinase-driven cassette removal (ESC/Blastocyst Approach). Using a unique second method, we employed the same vector (devoid of its selectable marker cassettes), microinjecting it along with redundant single guide RNAs (sgRNAs) and Cas9 mRNA into mouse zygotes (CRISPR/Zygote Approach). In both instances, we were able to achieve humanization of Bcl2l11 to the extent designed, remove all selection cassettes, and demonstrate the functionality of the conditionally removable, loxP flanked, 2.9-kbp intronic segment. PMID- 30301926 TI - Effects of coumaphos and imidacloprid on honey bee (Hymenoptera: Apidae) lifespan and antioxidant gene regulations in laboratory experiments. AB - The main objective of this study was to test comparatively the effects of two common insecticides on honey bee Apis mellifera worker's lifespan, food consumption, mortality, and expression of antioxidant genes. Newly emerged worker bees were exposed to organophosphate insecticide coumaphos, a neonicotinoid imidacloprid, and their mixtures. Toxicity tests were conducted along with bee midgut immunohistological TUNEL analyses. RT-qPCR assessed the regulation of 10 bee antioxidant genes linked to pesticide toxicity. We tested coumaphos at 92,600 ppb concentration, in combination with 5 and 20 ppb imidacloprid. Coumaphos induced significantly higher bee mortality, which was associated with down regulation of catalase compared to coumaphos and imidacloprid (5/20 ppb) mixtures, whereas, both imidacloprid concentrations independently had no effect on bee mortality. Mixture of coumaphos and imidacloprid reduced daily bee consumption of a control food patty to 10 mg from a coumaphos intake of 14.3 mg and 18.4 and 13.7 mg for imidacloprid (5 and 20) ppb, respectively. While coumaphos and imidacloprid mixtures induced down-regulation of antioxidant genes with noticeable midgut tissue damage, imidacloprid induced intensive gene up regulations with less midgut apoptosis. PMID- 30301927 TI - Losses of natural coastal wetlands by land conversion and ecological degradation in the urbanizing Chinese coast. AB - Coastal wetland ecosystems have experienced serious losses of area and ecological function and are currently facing worldwide challenges due to coastal development and global climate change. This study attempted to explore patterns and possible factors driving loss of natural coastal wetlands due to land conversion (permanent loss) and ecological degradation (temporal loss) in three urbanizing coastal city clusters, China in the period of 1990-2015. The natural coastal wetland area was substantially lost due to land conversion highly related to regional economic development. The ecological degradation, assessed as a function of surface water quality, resulted in much greater impairment area of natural coastal wetlands. This impairment was predominantly driven by inbound river pollutants' discharge, rather than local discharge. This study suggests that the ecological degradation should be considered as well as the land conversion loss for conserving the remaining natural coastal wetland ecosystems. The pollutant discharges from the inbound river watersheds need to be mitigated as the local discharges for reducing the functional degradation of the natural coastal wetlands while the regional economic development plan should consider the conservation needs of the remaining natural coastal wetlands worldwide. PMID- 30301928 TI - Effect of the Ratio of Magnetite Particle Size to Microwave Penetration Depth on Reduction Reaction Behaviour by H2. AB - In this study, we investigated reduction of magnetite by H2 during microwave irradiation. This process combines the advantages of microwave irradiation and using H2 as a reducing agent to mitigate CO2 emissions during the ironmaking process. Weight change measurements showed that a reduction of 75% was achieved after treatment under H2 for 60 min. For better understanding of the effective parameters in microwave chemistry, scanning electron microscopy, combined with energy-dispersive X-ray spectroscopy (SEM-EDX), was performed, which demonstrated a greater reduction of large particles (>40 MUm) than small particles. This behaviour could be attributed to the higher microwave absorption capability of large particles with a higher ratio of particle size to penetration depth (d/delta). Small particles behave as transparent material and are heated via conduction and/or convection; thus, there is no contribution from the catalytic effect of microwaves to the reduction reaction. Moreover, the reduction of Fe3O4 to Fe0.94O, followed by transformation to Fe, seems to proceed from the surface toward the centre of the particle despite the volumetric microwave heating. This could be due to the higher gas accessibility of iron oxide on the particle surface than in the particle centre. PMID- 30301929 TI - Information transfer in QT-RR dynamics: Application to QT-correction. AB - The relation between the electrical properties of the heart and the beating rate is essential for the heart functioning. This relation is central when calculating the "corrected QT interval" - an important measure of the risk of potentially lethal arrhythmias. We use the transfer entropy method from information theory to quantitatively study the mutual dynamics of the ventricular action potential duration (the QT interval) and the length of the beat-to-beat (RR) interval. We show that for healthy individuals there is a strong asymmetry in the information transfer: the information flow from RR to QT dominates over the opposite flow (from QT to RR), i.e. QT depends on RR to a larger extent than RR on QT. Moreover, the history of the intervals has a strong effect on the information transfer: at sufficiently long QT history length the information flow asymmetry inverts and the RR influence on QT dynamics weakens. Finally, we demonstrate that the widely used QT correction methods cannot properly capture the changes in the information flows between QT and RR. We conclude that our results obtained through a model-free informational perspective can be utilised to improve and test the QT correction schemes in clinics. PMID- 30301931 TI - BETting on YAP-TAZ.

PMID- 30301930 TI - Apelin inhibited epithelial-mesenchymal transition of podocytes in diabetic mice through downregulating immunoproteasome subunits beta5i. AB - The epithelial-mesenchymal transition (EMT) of podocytes had been reported to be involved in the glomerular fibrosis in diabetic kidney diseases, which was regulated by TGFbeta and NFkappaB pathways. And apelin, an adipokine which is upregulated in diabetic kidney diseases, was reported to be negatively correlated to TGFbeta in polycystic kidney disease and attenuate EMT in renal tubular cells. Therefore, it is hypothesized that apelin might inhibit the EMT of podocytes through downregulating the expression and activation of TGFbeta/Smad pathway in diabetic kidney diseases. The results showed that apelin in glomeruli of diabetic mice were increased and exogenous apelin inhibited the EMT of podocytes in diabetic mice, which were accompanied with the decreased expression of proteasome subunits beta5i. The results from beta5iKO mice confirmed that the inhibiting effects of apelin on EMT of podocytes in diabetic mice were dependent on beta5i. The results from culture podocytes showed that apelin decreased the degradation of pIkappaB and promoted the translocation of IkappaB into nucleus through decreasing the expression of beta5i, which would inhibit the promoting effects of NFkappaB on expression of TGFbeta and followed by decreased activation of Smad pathway and EMT in podocytes. In conclusion, apelin might act as an EMT suppressor for podocytes to decrease the process of glomerular fibrosis in diabetic mice. PMID- 30301934 TI - Tumor DNA-dependent protein kinase catalytic subunit expression is associated with hepatitis B surface antigen status and tumor progression in patients with hepatocellular carcinoma. AB - The DNA-dependent protein kinase catalytic subunit (DNA-PKcs), which plays an important role in the DNA damage response, has been reported to be associated with tumor progression in various carcinomas. However, the clinical significance of DNA-PKcs in hepatocellular carcinoma (HCC) patients remains unclear. In the present study, we determined the tumor expression of DNA-PKcs in 104 resected HCC specimens by immunohistochemistry. The DNA-PKcs expression was scored as follows; 0, negative staining; 1, staining of nuclei at the tumor edge; 2, staining of the nuclei deep within the tumor and/or the tumor cytoplasm. The relationships between tumor expression of DNA-PKcs and the clinical characteristics and patient outcomes were investigated. Among the 104 HCCs, the distribution of staining for DNA-PKcs was as follows: 32 tumors were assigned a score of 0, 27 tumors were assigned a score of 1, and 45 tumors were assigned a score of 2. Statistical analyses revealed that tumor DNA-PKcs expression was significantly associated with the HBs antigen (HBsAg) status, presence/absence of portal vein invasion, size of the largest tumor nodule (<3.0 cm/>3.0, cm), and the serum alpha fetoprotein level. Significant differences in the overall survival and recurrence free survival were observed between patients showing (staining score 1 or 2) and not showing (staining score 0) tumor DNA-PKcs expression (P = 0.049 and P = 0.045, respectively). Our results suggest that tumor expression of DNA-PKcs is associated with tumor progression, HBsAg status and the postoperative outcomes in patients with HCC. PMID- 30301935 TI - Naturally Occurring Variations Modulate the Activity of the HPV33 Early Promoter and its Affinity for the E2 Transcription Factor. AB - The human papillomavirus (HPV) Long Control Region (LCR) encompasses the early promoter (EP) that drives transcription of the E6 and E7 oncogenes in keratinocytes and HPV-associated cancers. In this study, the transcriptional activities of the HPV33 EP from the prototype LCR and from eight variants representative of the worldwide diversity of the virus were examined in primary human keratinocytes (PHK) and in the HeLa cervical carcinoma cell line by luciferase reporter-gene assays. Remarkably, the two variations with the greatest effect on the EP in PHK were C7732G and a 79-bp deletion that were associated with high-grade cervical lesions and persistent infections, respectively, in epidemiological studies. In contrast, the three variations most active in HeLa cells were C7537A, A7874C and A7879G. A7874C, which lies within an E2-binding sequence, is also shown to increase the activity and binding of E2 at this site. Collectively, these results indicate that naturally-occurring variations affect the HPV33 EP differentially in PHK than in cancer cells and, furthermore, that they can also alter its regulation by E2. These findings provide a molecular basis for rationalizing the results of previous epidemiological studies and for understanding the contribution of LCR polymorphisms to the oncogenicity and persistence of HPV33 infections. PMID- 30301933 TI - Development of a Molecular Adjuvant to Enhance Antigen-Specific CD8+ T Cell Responses. AB - Despite promising progress in malaria vaccine development, an efficacious subunit vaccine against P. falciparum remains to be licensed and deployed. This study aimed to improve on the immunogenicity of the leading liver-stage vaccine candidate (ChAd63-MVA ME-TRAP), known to confer protection by eliciting high levels of antigen-specific CD8+ T cells. We previously showed fusion of ME-TRAP to the human MHC class II invariant chain (Ii) could enhance CD8+ T cell responses in non-human primates, but did not progress to clinical testing due to potential risk of auto-immunity by vaccination of humans with a self-antigen. Initial immunogenicity analyses of ME-TRAP fused to subdomains of the Ii showed that the Ii transmembrane domain alone can enhance CD8+ T cell responses. Subsequently, truncated Ii sequences with low homology to human Ii were developed and shown to enhance CD8+ T cell responses. By systematically mutating the TM domain sequence, multimerization of the Ii chain was shown to be important for immune enhancement. We subsequently identified several proteins from a variety of microbial pathogens with similar characteristics, that also enhance the CD8+ T cell response and could therefore be used in viral vector vaccines when potent cell mediated immunity is required. PMID- 30301936 TI - Losing half the conductive area hardly impacts the water status of mature trees. AB - The water status of transpiring tree crowns depends on a hydraulic continuum from the soil matrix around roots to the sub-stomatal cavity of leaves, with a multitude of hydraulic resistances along this path. Although the stem xylem path may not be the most critical of these resistances, it had been suggested that a >50% interruption of that path by drought-stress-induced embolization (air filling) of conduits is critical for tree survival. Here we show that cutting the sapwood of mature, 35 m tall trees in half hardly affects crown water status and transpiration. Counter expectation, this first adult tree sapwood interception experiment revealed that shoot water potential in the canopy (assessed by using a 45 m canopy crane) either remained unaffected (spruce) or became less negative (beech), associated with small reductions in leaf diffusive conductance for water vapour. We conclude that the stem xylem of these trees has a large overcapacity and the tree hydraulics debate requires a critical re-visitation.

AB - Acute anterior uveitis (AAU) and the spondyloarthritis (SpA) subtypes ankylosing spondylitis, reactive arthritis and psoriatic arthritis are among the inflammatory diseases affected by the biology of the intestinal microbiome. In this Review, the relationship between AAU, SpA and the microbiome is discussed, with a focus on the major SpA risk gene HLA-B*27 and how it is associated with both intestinal tolerance and the loss of ocular immune privilege that can accompany AAU. We provide four potential mechanisms to account for how dysbiosis, barrier function and immune response contribute to the development of ocular inflammation and the pathogenesis of AAU. Finally, potential therapeutic avenues to target the microbiota for the clinical management of AAU and SpA are outlined.

AB - OBJECTIVE: To evaluate the Specific Test of Early Infant Motor Performance (STEP), a rapid screening test of preterm infants at risk for developmental delay. STUDY DESIGN: We prospectively studied 23 preterm infants' performance on the STEP and the Test of Infant Motor Performance (TIMP) at term and 3 months, and on the Bayley-III at 12 months. We investigated the psychometric qualities of the STEP and determined STEP cutoff scores for low and high-performing infants. RESULTS: STEP scores at term and 3 months strongly correlate with 12-month Bayley III gross motor and cognitive scaled scores, while TIMP scores did not. The STEP showed excellent reliability and required 6-10 min to administer. CONCLUSION: STEP is a short, easy to administer, early developmental assessment with unique scoring that emphasizes qualitative and quantitative aspects of muscle tone in movements and predicts 12-month Bayley gross motor and cognitive scaled scores.

AB - The elucidation of molecular events that confer tamoxifen resistance to estrogen receptor alpha (ER) positive breast cancer is of major scientific and therapeutic importance. Here, we report that LEM4 overexpression renders ER+ breast cancer cells resistant to tamoxifen by activating the cyclin D-CDK4/6 axis and the ERalpha signaling. We show that LEM4 overexpression accelerates tumor growth. Interaction with LEM4 stabilizes CDK4 and Rb, promotes Rb phosphorylation and the G1/S phase transition. LEM4 depletion or combined tamoxifen and PD0332991 treatment significantly reverses tamoxifen resistance. Furthermore, LEM4 interacts with and stabilizes both Aurora-A and ERalpha, promotes Aurora-A mediated phosphorylation of ERalpha-Ser167, leading to increase in ERalpha DNA binding and transactivation activity. Elevated levels of LEM4 correlates with poorer relapse-free survival in patients with ER+ breast cancer undergoing endocrine therapy. Thus, LEM4 represents a prognostic marker and an attractive target for breast cancer therapeutics. Functional antagonism of LEM4 could overcome tamoxifen resistance.

PMID- 30301942 TI - Simultaneous evaluation of anti-EGFR-induced tumour and adverse skin effects in a microfluidic human 3D co-culture model. AB - Antibody therapies targeting the epithelial growth factor receptor (EGFR) are being increasingly applied in cancer therapy. However, increased tumour containment correlates proportionally with the severity of well-known adverse events in skin. The prediction of the latter is not currently possible in conventional in vitro systems and limited in existing laboratory animal models. Here we established a repeated dose "safficacy" test assay for the simultaneous generation of safety and efficacy data. Therefore, a commercially available multi organ chip platform connecting two organ culture compartments was adapted for the microfluidic co-culture of human H292 lung cancer microtissues and human full thickness skin equivalents. Repeated dose treatment of the anti-EGFR-antibody cetuximab showed an increased pro-apoptotic related gene expression in the tumour microtissues. Simultaneously, proliferative keratinocytes in the basal layer of the skin microtissues were eliminated, demonstrating crucial inhibitory effects on the physiological skin cell turnover. Furthermore, antibody exposure modulated the release of CXCL8 and CXCL10, reflecting the pattern changes seen in antibody treated patients. The combination of a metastatic tumour environment with a miniaturized healthy organotypic human skin equivalent make this "safficacy" assay an ideal tool for evaluation of the therapeutic index of EGFR inhibitors and other promising oncology candidates.

AB - Ischemic stroke-induced neuronal cell death results in the permanent disabling of brain function. Apoptotic mechanisms are thought to play a prominent role in neuronal injury and ample evidence implicates Fas signaling in mediating cell death. In this study, we describe the neuroprotective effects of a Fas-blocking peptide (FBP) that by obstructing Fas signaling in cerebral ischemia inhibits apoptosis. Using an intranasal administration route in a rat model of focal cerebral ischemia, we demonstrate that nose-to-brain delivery of FBP after middle cerebral artery occlusion (MCAO) surgery results in the delivery and retention of FBP in Fas-expressing ischemic areas of the brain. A single intranasal administration of 2 mg/kg FBP resulted in significantly reduced neuronal cell death by inhibiting Fas-mediated apoptosis leading to decreased infarct volumes, reduced neurologic deficit scores and recovery from cerebral ischemia. Intranasally delivered FBP might be a promising strategy for the treatment of cerebral ischemic stroke.

AB - Research findings implicate cerebral glutamate in the pathophysiology of schizophrenia, including genetic studies reporting associations with glutamatergic neurotransmission. The extent to which aberrant glutamate levels can be explained by genetic factors is unknown, and if glutamate can serve as a marker of genetic susceptibility for schizophrenia remains to be established. We investigated the heritability of cerebral glutamate levels and whether a potential association with schizophrenia spectrum disorders could be explained by genetic factors. Twenty-three monozygotic (MZ) and 20 dizygotic (DZ) proband pairs con- or discordant for schizophrenia spectrum disorders, along with healthy control pairs (MZ = 28, DZ = 18) were recruited via the National Danish Twin Register and the Psychiatric Central Register (17 additional twins were scanned without their siblings). Glutamate levels in the left thalamus and the anterior cingulate cortex (ACC) were measured using 1[H]-magnetic resonance spectroscopy at 3 Tesla and analyzed by structural equation modeling. Glutamate levels in the left thalamus were heritable and positively correlated with liability for schizophrenia spectrum disorders (phenotypic correlation, 0.16, [0.02-0.29]; p = 0.010). The correlation was explained by common genes influencing both the levels of glutamate and liability for schizophrenia spectrum disorders. In the ACC, glutamate and glx levels were heritable, but not correlated to disease liability. Increases in thalamic glutamate levels found in schizophrenia spectrum disorders are explained by genetic influences related to the disease, and as such the measure could be a potential marker of genetic susceptibility, useful in early detection and stratification of patients with psychosis. PMID- 30301945 TI - Decision-making of the benthic diatom Seminavis robusta searching for inorganic nutrients and pheromones. AB - Microorganisms encounter a diversity of chemical stimuli that trigger individual responses and influence population dynamics. However, microbial behavior under the influence of different incentives and microbial decision-making is poorly understood. Benthic marine diatoms that react to sexual attractants as well as to nutrient gradients face such multiple constraints. Here, we document and model behavioral complexity and context-sensitive responses of these motile unicellular algae to sex pheromones and the nutrient silicate. Throughout the life cycle of the model diatom Seminavis robusta nutrient-starved cells localize sources of silicate by combined chemokinetic and chemotactic motility. However, with an increasing need for sex to restore the initial cell size, a change in behavior favoring the attraction-pheromone-guided search for a mating partner takes place. When sex becomes inevitable to prevent cell death, safeguard mechanisms are abandoned, and cells prioritize the search for mating partners. Such selection processes help to explain biofilm organization and to understand species interactions in complex communities. PMID- 30301946 TI - Induction of antibacterial proteins and peptides in the coprophilous mushroom Coprinopsis cinerea in response to bacteria. AB - Bacteria are the main nutritional competitors of saprophytic fungi during colonization of their ecological niches. This competition involves the mutual secretion of antimicrobials that kill or inhibit the growth of the competitor. Over the last years it has been demonstrated that fungi respond to the presence of bacteria with changes of their transcriptome, but the significance of these changes with respect to competition for nutrients is not clear as functional proof of the antibacterial activity of the induced gene products is often lacking. Here, we report the genome-wide transcriptional response of the coprophilous mushroom Coprinopsis cinerea to the bacteria Bacillus subtilis and Escherichia coli. The genes induced upon co-cultivation with each bacterium were highly overlapping, suggesting that the fungus uses a similar arsenal of effectors against Gram-positive and -negative bacteria. Intriguingly, the induced genes appeare to encode predominantly secreted peptides and proteins with predicted antibacterial activities, which was validated by comparative proteomics of the C. cinerea secretome. Induced members of two putative antibacterial peptide and protein families in C. cinerea, the cysteine-stabilized alphabeta defensins (Csalphabeta-defensins) and the GH24-type lysozymes, were purified, and their antibacterial activity was confirmed. These results provide compelling evidence that fungi are able to recognize the presence of bacteria and respond with the expression of an arsenal of secreted antibacterial peptides and proteins. PMID- 30301947 TI - Stress-induced changes in social dominance are scaled by AMPA-type glutamate receptor phosphorylation in the medial prefrontal cortex. AB - The establishment and maintenance of social dominance are critical for social stability and the survival and health of individual animals. Stress lead to depression and a decrease in the social status of depressed persons is a risk factor for suicide. Therefore, we explored the mechanistic and behavioral links among stress, depression, and social dominance and found that mice subjected to chronic restraint stress (CRS), an animal model of stress-induced depression, showed decreased social dominance as measured by a dominance tube test. Importantly, this submissive behavior was occluded by the antidepressant, fluoxetine, a selective serotonin reuptake inhibitor. It is known that social dominance is controlled by synaptic efficacy in the medial prefrontal cortex (mPFC) and that AMPA-type glutamate receptor (AMPA-R) is a key molecule for synaptic efficacy. We found that the phosphorylation on AMPA-R was bidirectionally changed by CRS and fluoxetine in the mPFC of mice with CRS. Moreover, we found a strong correlation between social dominance and AMPA-R phosphorylation that regulates synaptic efficacy by modulating the synaptic targeting of AMPA-R. Our correlational analysis of the behavior and biochemistry of the CRS model suggests that AMPA-R phosphorylation in the mPFC may serve as a biomarker of social dominance related to stress.

AB - We report the fabrication and measurement of top gated epitaxial graphene p-n junctions where exfoliated hexagonal boron nitride (h-BN) is used as the gate dielectric. The four-terminal longitudinal resistance across a single junction is well quantized at the von Klitzing constant [Formula: see text] with a relative uncertainty of 10-7. After the exploration of numerous parameter spaces, we summarize the conditions upon which these devices could function as potential resistance standards. Furthermore, we offer designs of programmable electrical resistance standards over six orders of magnitude by using external gating. PMID- 30301949 TI - Microclimate exerts greater control over litter decomposition and enzyme activity than litter quality in an alpine forest-tundra ecotone. AB - Plant litter decomposition is an important biogeochemical process in terrestrial ecosystems. Although climate and substrate quality controls over litter decomposition are reasonably well understood, their impacts on lignocellulose degradation and lignocellulolytic enzymes remain elusive. Here, the decomposition of three leaf litters derived from Salix paraplesia (SP), Deyeuxia scabrescens (DS), and Ajuga ovalifolia (AO), was studied across an alpine forest-tundra ecotone during one snow-covered season with the objective of distinguishing between the effects of microclimate and litter quality on litter decomposition rates and lignocellulolytic enzymes. The results showed that both microclimate and litter quality affected lignocellulose degradation rates and lignocellulolytic enzyme activities; however, microclimate factors had the greater effects. Interestingly, freeze-thaw cycles and moisture were the predominant factors explaining the variations in decomposition rate and enzyme activities. Higher cellulose degradation rates were associated with higher cellulose concentrations. Cellulolytic enzymes had a greater effect on litter decomposition than did ligninolytic enzymes at the early decomposition stage. Litter decomposition and enzyme activities should be given more attention under global climate change, as the direction and magnitude of changes in microclimate factors and litter quality could strongly influence the nutrient cycling and energy fluxes of alpine ecosystems. PMID- 30301950 TI - Tree shrew as a new animal model to study the pathogenesis of avian influenza (H9N2) virus infection. AB - Outbreaks of avian influenza virus continue to pose threats to human health. Animal models such as the mouse, ferret, and macaque are used to understand the pathogenesis of avian influenza virus infection in humans. We previously reported that the tree shrew (Tupaia belangeri, family Tupaiidae), which is regarded as a "low-level primate", has alpha2,3- and alpha2,6-linked sialic acid receptor distributions similar to those of humans and is potentially a useful mammalian model for studying mild human influenza (H1N1) virus infection. In this study, we used the tree shrew experimental model to investigate the pathogenesis of avian influenza A (H9N2) virus infection and the effect of the E627K mutation in the PB2 gene, an adaptation to mammalian hosts. Evidence of disease, virus titers in the upper and lower respiratory tract, histopathology and induction of proinflammatory cytokines are described. We also established ex vivo culture models of tree shrew respiratory tissues to study the tropism and replication of the H9N2 virus. Our results demonstrated that the tree shrew is a viable new in vivo experimental model for avian influenza research that provides results comparable to those observed in ferrets. The disease spectrum and pathogenesis in tree shrews correlate well with what is observed in humans. PMID- 30301952 TI - A position on vision. PMID- 30301951 TI - Circadian monitoring as an aging predictor. AB - The ageing process is associated with sleep and circadian rhythm (SCR) frailty, as well as greater sensitivity to chronodisruption. This is essentially due to reduced day/night contrast, decreased sensitivity to light, napping and a more sedentary lifestyle. Thus, the aim of this study is to develop an algorithm to identify a SCR phenotype as belonging to young or aged subjects. To do this, 44 young and 44 aged subjects were recruited, and their distal skin temperature (DST), activity, body position, light, environmental temperature and the integrated variable TAP rhythms were recorded under free-living conditions for five consecutive workdays. Each variable yielded an individual decision tree to differentiate between young and elderly subjects (DST, activity, position, light, environmental temperature and TAP), with agreement rates of between 76.1% (light) and 92% (TAP). These decision trees were combined into a unique decision tree that reached an agreement rate of 95.3% (4 errors out of 88, all of them around the cut-off point). Age-related SCR changes were very significant, thus allowing to discriminate accurately between young and aged people when implemented in decision trees. This is useful to identify chronodisrupted populations that could benefit from chronoenhancement strategies.

PMID- 30301953 TI - The neural mechanisms and circuitry of the pair bond. AB - Love is one of our most powerful emotions, inspiring some of the greatest art, literature and conquests of human history. Although aspects of love are surely unique to our species, human romantic relationships are displays of a mating system characterized by pair bonding, likely built on ancient foundational neural mechanisms governing individual recognition, social reward, territorial behaviour and maternal nurturing. Studies in monogamous prairie voles and mice have revealed precise neural mechanisms regulating processes essential for the pair bond. Here, we discuss current viewpoints on the biology underlying pair bond formation, its maintenance and associated behaviours from neural and evolutionary perspectives. PMID- 30301955 TI - Fasting enhances extinction retention and prevents the return of fear in humans. AB - Fear is prone to return following extinction that is the basis of exposure therapy for fear-related disorders. Manipulations that enhance the extinction process can be beneficial for treatment. Animal studies have shown that fasting or caloric restriction can enhance extinction and inhibit the return of fear. The present study examined the effects of fasting on fear acquisition, extinction, and the return of fear in humans. One hundred and twenty-five male participants were randomized into a fasting group and food group and exposed to a Pavlovian fear conditioning paradigm. Changes in plasma cortisol and ghrelin levels were examined using enzyme-linked immunosorbent assays. One-night fasting had no effect on fear acquisition but enhanced fear extinction retention and prevented the return of fear, and this effect persisted for at least 6 months. This procedure was also effective for remote fear memory. Plasma ghrelin levels were elevated after fasting and had a negative relationship with the fear response in spontaneous recovery test. However, overnight fasting did not affect cortisol levels. These findings indicate that fasting enhances extinction retention and prevents the return of fear, without influencing fear memory formation. We propose that this novel procedure may open new avenues for promoting extinction based therapies for fear-related disorders. PMID- 30301956 TI - Verbal instructions override the meaning of facial expressions. AB - Psychological research has long acknowledged that facial expressions can implicitly trigger affective psychophysiological responses. However, whether verbal information can alter the meaning of facial emotions and corresponding response patterns has not been tested. This study examined emotional facial expressions as cues for instructed threat-of-shock or safety, with a focus on defensive responding. In addition, reversal instructions were introduced to test the impact of explicit safety instructions on fear extinction. Forty participants were instructed that they would receive unpleasant electric shocks, for instance, when viewing happy but not angry faces. In a second block, instructions were reversed (e.g., now angry faces cued shock). Happy, neutral, and angry faces were repeatedly presented, and auditory startle probes were delivered in half of the trials. The defensive startle reflex was potentiated for threat compared to safety cues. Importantly, this effect occurred regardless of whether threat was cued by happy or angry expressions. Although the typical pattern of response habituation was observed, defense activation to newly instructed threat cues remained significantly enhanced in the second part of the experiment, and it was more pronounced in more socially anxious participants. Thus, anxious individuals did not exhibit more pronounced defense activation compared to less anxious participants, but their defense activation was more persistent. PMID- 30301957 TI - Exceptional catalytic effects of black phosphorus quantum dots in shuttling-free lithium sulfur batteries. AB - Lithium sulfur batteries with high energy densities are promising next-generation energy storage systems. However, shuttling and sluggish conversion of polysulfides to solid lithium sulfides limit the full utilization of active materials. Physical/chemical confinement is useful for anchoring polysulfides, but not effective for utilizing the blocked intermediates. Here, we employ black phosphorus quantum dots as electrocatalysts to overcome these issues. Both the experimental and theoretical results reveal that black phosphorus quantum dots effectively adsorb and catalyze polysulfide conversion. The activity is attributed to the numerous catalytically active sites on the edges of the quantum dots. In the presence of a small amount of black phosphorus quantum dots, the porous carbon/sulfur cathodes exhibit rapid reaction kinetics and no shuttling of polysulfides, enabling a low capacity fading rate (0.027% per cycle over 1000 cycles) and high areal capacities. Our findings demonstrate application of a metal-free quantum dot catalyst for high energy rechargeable batteries. PMID- 30301958 TI - The genetic landscape of 5T models for multiple myeloma. AB - Murine models for multiple myeloma (MM) are often used to investigate pathobiology of multiple myeloma and disease progression. Unlike transgenic mice models, where it is known which oncogene is driving MM disease, the somatic aberrations of spontaneous syngeneic 5T models of MM have not yet been reported. Here, we analyzed the copy-number alterations (CNA) and mutational landscape of 5T2, 5T33vv and 5TGM1 murine MM models using whole-genome and whole-exome sequencing. Forty four percent of the genome of 5T2 cells is affected by CNAs while this was only 11% and 17% for 5T33vv and 5TGM1 cells, respectively. We found that up to 69% of the genes linked to gain of 1q or deletion of 13q in MM patients are present as respectively gains in 5T2 cells or deletions in 5T33 and 5TGM1 cells. Exome sequencing furthermore revealed mutations of genes involved in RAS/MAPK, PI3K/AKT1 and JAK/STAT signaling, DNA damage response, cell cycle, epigenetic regulation and extracellular matrix organization. We observed a statistically significant overlap of genes mutated in the 5T models and MM patients. Overall, the genetic landscape of the 5T models is heterogeneous with a high number of aberrations involving genes in various multiple myeloma-related pathways. PMID- 30301960 TI - Necessity for a paradigm shift in the treatment of pediatric obesity. PMID- 30301961 TI - Obesity-associated family with sequence similarity 13, member A (FAM13A) is dispensable for adipose development and insulin sensitivity. AB - BACKGROUND: Obesity and its associated morbidities represent the major and most rapidly expanding world-wide health epidemic. Recent genome-wide association studies (GWAS) reveal that single nucleotide polymorphism (SNP) variant in the Family with Sequence Similarity 13, Member A (FAM13A) gene is strongly associated with waist-hip ratio (WHR) with adjustment for body mass index (BMI) (WHRadjBMI). However, the function of FAM13A in adipose development and obesity remains largely uncharacterized. METHODS: The expression of FAM13A in adipose tissue depots were investigated using lean, genetic obese and high fat diet-induced obese (DIO) animal models and during adipocyte differentiation. Stromal vascular cells (SVCs) or 3T3-L1 cells with gain and loss of function of FAM13A were used to determine the involvement of FAM13A in regulating adipocyte differentiation. Adipose development and metabolic homeostasis in Fam13a-/- mice were characterized under normal chow and high fat diet feeding. RESULTS: Murine FAM13A expression was nutritionally regulated and dramatically reduced in epididymal and subcutaneous fat in genetic and diet-induced obesity. Its expression was enriched in mature adipocytes and significantly upregulated during murine and human adipogenesis potentially through a peroxisome proliferator-activated receptor gamma (PPARgamma)-dependent mechanism. However, Fam13a-/- mice only exhibited a tendency of higher adiposity and were not protected from DIO and insulin resistance. While Fam13a-/- SVCs maintained normal adipogenesis, overexpression of FAM13A in 3T3-L1 preadipocytes downregulated beta-catenin signaling and rendered preadipocytes more susceptible to apoptosis. Moreover, FAM13A overexpression largely blocked adipogenesis induced by a standard hormone cocktail, but adipogenesis can be partially rescued by the addition of PPARgamma agonist pioglitazone at an early stage of differentiation. CONCLUSIONS: Our results suggest that FAM13A is dispensable for adipose development and insulin sensitivity. Yet the expression of FAM13A needs to be tightly controlled in adipose precursor cells for their proper survival and downstream adipogenesis. These data provide novel insights into the link between FAM13A and obesity. PMID- 30301959 TI - Persistent platelet activation and apoptosis in virologically suppressed HIV infected individuals. AB - Cardiovascular diseases and thrombotic events became major clinical problems in the combined antiretroviral therapy (cART) era. Although the precise mechanisms behind these clinical problems have not been fully elucidated, a persistent pro inflammatory state plays a central role. As platelets play important roles on both, thrombus formation and inflammatory/immune response, we aimed at investigating platelet function in HIV-infected subjects virologically controlled through cART. We evaluate parameters of activation, mitochondrial function and activation of apoptosis pathways in platelets from 30 HIV-infected individuals under stable cART and 36 healthy volunteers. Despite viral control achieved through cART, HIV-infected individuals exhibited increased platelet activation as indicated by P-selectin expression and platelet spreading when adhered on fibrinogen-coated surfaces. Platelets from HIV-infected subjects also exhibited mitochondrial dysfunction and activation of apoptosis pathways. Finally, thrombin stimuli induced lower levels of P-selectin translocation and RANTES secretion, but not TXA2 synthesis, in platelets from HIV-infected individuals compared to control; and labeling of platelet alpha granules showed reduced granule content in platelets from HIV-infected individuals when compared to healthy subjects. In summary, platelets derived from HIV-infected individuals under stable cART exhibit a phenotype of increased activation, activation of the intrinsic pathway of apoptosis and undermined granule secretion in response to thrombin. PMID- 30301962 TI - High-fat diet consumption alters energy metabolism in the mouse hypothalamus. AB - BACKGROUND/OBJECTIVES: High-fat diet consumption is known to trigger an inflammatory response in the hypothalamus, which has been characterized by an initial expression of pro-inflammatory genes followed by hypothalamic astrocytosis, microgliosis, and the appearance of neuronal injury markers. The specific effects of high-fat diet on hypothalamic energy metabolism and neurotransmission are however not yet known and have not been investigated before. SUBJECTS/METHODS: We used 1H and 13C magnetic resonance spectroscopy (MRS) and immunofluorescence techniques to evaluate in vivo the consequences of high-saturated fat diet administration to mice, and explored the effects on hypothalamic metabolism in three mouse cohorts at different time points for up to 4 months. RESULTS: We found that high-fat diet increases significantly the hypothalamic levels of glucose (P < 0.001), osmolytes (P < 0.001), and neurotransmitters (P < 0.05) from 2 months of diet, and alters the rates of metabolic (P < 0.05) and neurotransmission fluxes (P < 0.001), and the contribution of non-glycolytic substrates to hypothalamic metabolism (P < 0.05) after 10 weeks of high-fat feeding. CONCLUSIONS/INTERPRETATION: We report changes that reveal a high-fat diet-induced alteration of hypothalamic metabolism and neurotransmission that is quantifiable by 1H and 13C MRS in vivo, and present the first evidence of the extension of the inflammation pathology to a localized metabolic imbalance. PMID- 30301963 TI - Levels of adherence needed to achieve significant weight loss. AB - BACKGROUND/OBJECTIVES: Positive associations have been found between adherence and weight loss in behavioral weight-management interventions. However, less attention has been given to the level of adherence needed to reach clinically significant weight loss. This study examined the levels of adherence associated with a >= 5% - < 10% or >= 10% weight loss in a community-based, intensive behavioral weight management program, Weight Watchers(r) (WW), which included three modes of access: (1) 24-weekly WW meetings over 6 months, (2) the WW member website, and (3) the WW mobile application. METHODS: A total of 292 participants were randomized to a WW (n = 147) or a self-help (SH) (n = 145) condition. To assess the impact of adherence, only participants in the WW condition were included in analyses (n = 147). Adherence was defined as use of the three modes of access. Measured heights and weights were obtained at baseline and 6 months. Receiver-operating characteristic curve analyses were conducted to determine the minimal level of adherence associated with clinically significant weight loss. RESULTS: In a 6-month period, increased likelihood of achieving a weight loss >= 5% - < 10% was associated with attending approximately one-third (35.4%) of weekly meetings, use of the member website about 25% of days, and use of the mobile application 16.1% of days. Attendance at approximately two-thirds (64.5%) of meetings, use of the member website 41.6% of days, and use of the mobile application 14.7% of days were associated with a clinically significant weight loss of >= 10%. Meeting attendance was the strongest predictor of weight loss at 6 months. CONCLUSIONS: Although adherence to a behavioral weight management program was an important predictor of weight loss, extremely high levels were not needed to achieve clinically significant weight loss. These results are important to help patients and treatment providers understand realistic goals for weight management. PMID- 30301964 TI - Interventions for treating children and adolescents with overweight and obesity: an overview of Cochrane reviews. AB - Children and adolescents with overweight and obesity are a global health concern. This is an integrative overview of six Cochrane systematic reviews, providing an up-to-date synthesis of the evidence examining interventions for the treatment of children and adolescents with overweight or obesity. The data extraction and quality assessments for each review were conducted by one author and checked by a second. The six high quality reviews provide evidence on the effectiveness of behaviour changing interventions conducted in children <6 years (7 trials), 6-11 years (70 trials), adolescents 12-17 years (44 trials) and interventions that target only parents of children aged 5-11 years (20 trials); in addition to interventions examining surgery (1 trial) and drugs (21 trials). Most of the evidence was derived from high-income countries and published in the last two decades. Collectively, the evidence suggests that multi-component behaviour changing interventions may be beneficial in achieving small reductions in body weight status in children of all ages, with low adverse event occurrence were reported. More research is required to understand which specific intervention components are most effective and in whom, and how best to maintain intervention effects. Evidence from surgical and drug interventions was too limited to make inferences about use and safety, and adverse events were a serious consideration.

PMID- 30301966 TI - Genetic background influences weight-loss trajectories on the mid-term after bariatric surgery. AB - Bariatric surgery (BS) is a highly effective therapy for morbid obesity, yet with a wide inter-individual variability on weight-loss responses. To determine genetic influence on weight loss after BS we compared the within-pairs difference in maximum percentage excess weight loss (%EWL) and the within-pairs %EWL differences over a mean follow-up of 53.6 +/- 36.4 months between 47 pairs of first-degree relatives and 47 genetically unrelated control pairs. Within-pairs maximum %EWL difference was similar between first-degree related pairs and control pairs (p = 0.100). Within-pairs %EWL difference increased through follow up (p < 0.001). However, effect of time was different depending on genetic background (ptime*group = 0.001). Increased variability in mid-term weight response was present in unrelated pairs but not in first-degree pairs (p < 0.001 and p = 0.535, respectively). To assess shared environment influence, 16 married couples were identified and 16 unrelated and non-cohabiting matched pairs were also analyzed. In these analysis within-pairs difference in %EWL also increase over time (p = 0.025) but no group by time effect was observed (ptime*group = 0.177). In conclusion first-degree related participants showed closer weight trajectories after BS time than genetically unrelated subjects. Genetic background might partially explain the variability in mid-term weight-loss after BS. PMID- 30301967 TI - Temporal immmunometabolic profiling of adipose tissue in HFD-induced obesity: manifestations of mast cells in fibrosis and senescence. AB - BACKGROUND/OBJECTIVES: Chronic low-grade inflammation/meta-inflammation in adipose tissue leads to obesity-associated metabolic complications. Despite growing understanding, the roles of immune cell subsets, their interrelationship, and chronological events leading to progression of obesity-associated insulin resistance (IR) remains unclear. METHODS: We carried out temporal immunometabolic profiling of adipose tissue from C57BL/6 mice fed a high-fat diet (HFD) for 4, 8, 12, 16, and 20 weeks. We used clodronate sodium liposomes (CLODs) to deplete macrophages and disodium cromoglycate sodium liposomes (DSCGs) to stabilize mast cells. RESULTS: In the temporal HFD settings, mice showed progressive glucose intolerance, insulin resistance, and adipose tissue senescence. Histochemistry analysis of epididymal white adipose tissue (eWAT) using picro-sirius red and Masson's trichrome staining showed extensive collagen deposition in the 16th and 20th weeks. Flow cytometry analysis of the stromal vascular fraction (SVF) from eWAT revealed T-cell subsets as early-phase components and pro-inflammatory macrophages, as well as mast cells as the later phase components during obesity progression. In our therapeutic strategies, macrophage depletion by CLOD and mast stabilization by DSCG attenuated obesity, adipose tissue fibrosis, and improved whole-body glucose homeostasis. In addition, mast cell stabilization also attenuated senescence (p53 and X-gal staining) in eWAT, signifying the role of mast cells over macrophages during obesity. CONCLUSION: New-generation mast cell stabilizers can be exploited for the treatment of obesity-associated metabolic complications. PMID- 30301968 TI - Evaluation of chitotriosidase as a biomarker for adipose tissue inflammation in overweight individuals and type 2 diabetic patients. AB - BACKGROUND: Overweight and obesity can lead to adipose tissue inflammation, which causes insulin resistance and on the long-term type 2 diabetes mellitus (T2D). The inflammatory changes of obese-adipose tissue are characterized by macrophage infiltration and activation, but validated circulating biomarkers for adipose tissue inflammation for clinical use are still lacking. One of the most secreted enzymes by activated macrophages is chitotriosidase (CHIT1). OBJECTIVE: To test whether circulating CHIT1 enzymatic activity levels reflect adipose tissue inflammation. METHODS: Plasma and adipose tissue samples of 105 subjects (35 lean, 37 overweight, and 33 T2D patients) were investigated. CHIT1 mRNA levels were determined in adipose tissue-resident innate immune cells. CHIT1 mRNA levels, protein abundance, and plasma enzymatic activity were subsequently measured in adipose tissue biopsies and plasma of control subjects with varying levels of obesity and adipose tissue inflammation as well as in T2D patients. RESULTS: In adipose tissue, CHIT1 mRNA levels were higher in stromal vascular cells compared to adipocytes, and higher in adipose tissue-residing macrophages compared to circulating monocytes (p < 0.001). CHIT1 mRNA levels in adipose tissue were enhanced in overweightcompared to lean subjects and even more in T2D patients (p < 0.05). In contrast, plasma CHIT1 enzymatic activity did not differ between lean, overweight subjects and T2D patients. A mutation of the CHIT1 gene decreases plasma CHIT1 activity. CONCLUSIONS: CHIT1 is expressed by adipose tissue macrophages and expression is higher in overweight subjects and T2D patients, indicating its potential as tissue biomarker for adipose tissue inflammation. However, these differences do not translate into different plasma CHIT1 activity levels. Moreover, a common CHIT1 gene mutation causing loss of plasma CHIT1 activity interferes with its use as a biomarker of adipose tissue inflammation. These results indicate that plasma CHIT1 activity is of limited value as a circulating biomarker for adipose tissue inflammation in human subjects. PMID- 30301969 TI - Uncovering association networks through an eQTL analysis involving human miRNAs and lincRNAs. AB - Non-coding RNAs (ncRNA) have an essential role in the complex landscape of human genetic regulatory networks. One area that is poorly explored is the effect of genetic variations on the interaction between ncRNA and their targets. By integrating a significant amount of public data, the present study cataloged the vast landscape of the regulatory effect of microRNAs (miRNA) and long intergenic noncoding RNAs (lincRNA) in the human genome. An expression quantitative trait loci (eQTL) analysis was used to identify genetic variants associated with miRNA and lincRNA and whose genotypes affect gene expression. Association networks were built for eQTL associated to traits of clinical and/or pharmacological relevance. PMID- 30301971 TI - There's NO limit. PMID- 30301970 TI - Replacing the Draize eye test: Impedance spectroscopy as a 3R method to discriminate between all GHS categories for eye irritation. AB - Highly invasive animal based test procedures for risk assessment such as the Draize eye test are under increasing criticism due to poor transferability for the human organism and animal-welfare concerns. However, besides all efforts, the Draize eye test is still not completely replaced by alternative animal-free methods. To develop an in vitro test to identify all categories of eye irritation, we combined organotypic cornea models based on primary human cells with an electrical readout system that measures the impedance of the test models. First, we showed that employing a primary human cornea epithelial cell based model is advantageous in native marker expression to the primary human epidermal keratinocytes derived models. Secondly, by employing a non-destructive measuring system based on impedance spectroscopy, we could increase the sensitivity of the test system. Thereby, all globally harmonized systems categories of eye irritation could be identified by repeated measurements over a period of 7 days. Based on a novel prediction model we achieved an accuracy of 78% with a reproducibility of 88.9% to determine all three categories of eye irritation in one single test. This could pave the way according to the 3R principle to replace the Draize eye test. PMID- 30301972 TI - Small RNA-based antimicrobial immunity. AB - Protection against microbial infection in eukaryotes is provided by diverse cellular and molecular mechanisms. Here, we present a comparative view of the antiviral activity of virus-derived small interfering RNAs in fungi, plants, invertebrates and mammals, detailing the mechanisms for their production, amplification and activity. We also highlight the recent discovery of viral PIWI interacting RNAs in animals and a new role for mobile host and pathogen small RNAs in plant defence against eukaryotic pathogens. In turn, viruses that infect plants, insects and mammals, as well as eukaryotic pathogens of plants, have evolved specific virulence proteins that suppress RNA interference (RNAi). Together, these advances suggest that an antimicrobial function of the RNAi pathway is conserved across eukaryotic kingdoms. PMID- 30301973 TI - Publisher Correction: T cells under starter's orders.

PMID- 30301974 TI - The oral microbiota: dynamic communities and host interactions. AB - The dynamic and polymicrobial oral microbiome is a direct precursor of diseases such as dental caries and periodontitis, two of the most prevalent microbially induced disorders worldwide. Distinct microenvironments at oral barriers harbour unique microbial communities, which are regulated through sophisticated signalling systems and by host and environmental factors. The collective function of microbial communities is a major driver of homeostasis or dysbiosis and ultimately health or disease. Despite different aetiologies, periodontitis and caries are each driven by a feedforward loop between the microbiota and host factors (inflammation and dietary sugars, respectively) that favours the emergence and persistence of dysbiosis. In this Review, we discuss current knowledge and emerging mechanisms governing oral polymicrobial synergy and dysbiosis that have both enhanced our understanding of pathogenic mechanisms and aided the design of innovative therapeutic approaches for oral diseases.

AB - A new electrically small antenna with size ka = 0.415 is presented, fabricated and measured in this work. This is intrinsically matched to 50 Omega, has omni directional and linear-polarized radiation pattern in the horizontal plane with maximum directivity of 1.75 dBi and simulated radiation efficiency of 93%. The antenna in combination with a low-complex and co-planar rectifier with one single diode forms a high efficient and sensitive electrically small rectenna with ka = 0.53 at 868 MHz (UHF RFID-band in Europe). The latter has measured efficiency 22.5% for -19 dBm power input and sensitivity of -44 dBm (or equivalently 0.00028 MUW/cm2 power density), while at 2.25 MUW/cm2 is able to supply continuously, i.e., without a boost converter or use of any energy tank, a small electrical device with 118 MUW. In order to increase the dc output voltage and the delivered dc power to the load for lower power density levels, rectenna-array configuration is exploited. Application to batteryless, backscatter wireless sensor node powering is discussed. Specifically, for a power density of 0.1237 MUW/cm2 the RF energy harvesting system delivers 172 MUW at 2.85 V every 22.5 s. PMID- 30301979 TI - Long non-coding RNA CCRR controls cardiac conduction via regulating intercellular coupling. AB - Long non-coding RNAs (lncRNAs) have emerged as a new class of gene expression regulators playing key roles in many biological and pathophysiological processes. Here, we identify cardiac conduction regulatory RNA (CCRR) as an antiarrhythmic lncRNA. CCRR is downregulated in a mouse model of heart failure (HF) and in patients with HF, and this downregulation slows cardiac conduction and enhances arrhythmogenicity. Moreover, CCRR silencing induces arrhythmias in healthy mice. CCRR overexpression eliminates these detrimental alterations. HF or CCRR knockdown causes destruction of intercalated discs and gap junctions to slow longitudinal cardiac conduction. CCRR overexpression improves cardiac conduction by blocking endocytic trafficking of connexin43 (Cx43) to prevent its degradation via binding to Cx43-interacting protein CIP85, whereas CCRR silence does the opposite. We identified the functional domain of CCRR, which can reproduce the functional roles and pertinent molecular events of full-length CCRR. Our study suggests CCRR replacement a potential therapeutic approach for pathological arrhythmias. PMID- 30301982 TI - Gone to the dark side: bacteria thrive 600 metres below Earth's surface. PMID- 30301978 TI - A missense variant in SLC39A8 is associated with severe idiopathic scoliosis. AB - Genetic factors predictive of severe adolescent idiopathic scoliosis (AIS) are largely unknown. To identify genetic variation associated with severe AIS, we performed an exome-wide association study of 457 severe AIS cases and 987 controls. We find a missense SNP in SLC39A8 (p.Ala391Thr, rs13107325) associated with severe AIS (P = 1.60 * 10-7, OR = 2.01, CI = 1.54-2.62). This pleiotropic SNP was previously associated with BMI, blood pressure, cholesterol, and blood manganese level. We replicate the association in a second cohort (841 cases and 1095 controls) resulting in a combined P = 7.02 * 10-14, OR = 1.94, CI = 1.63 2.34. Clinically, the minor allele of rs13107325 is associated with greater spinal curvature, decreased height, increased BMI and lower plasma manganese in our AIS cohort. Functional studies demonstrate reduced manganese influx mediated by the SLC39A8 p.Ala391Thr variant and vertebral abnormalities, impaired growth, and decreased motor activity in slc39a8 mutant zebrafish. Our results suggest the possibility that scoliosis may be amenable to dietary intervention. PMID- 30301983 TI - Tapeworm DNA hints at discomforts of life in a medieval trading hub.

AB - The present paper describes an extremely efficient, reproducible and inexpensive chemical handling method for converting the nuclear wastes contaminated by radioactive cesium to stable inorganic crystal, pollucite (CsAlSi2O6), which is promising as a form of the final storage. In this processing, the clays are used as a source for aluminum and silicon, and it is important to get a well-mixed homogenous solution by the aid of some heat and pressure. The present method proposes the use of ethylene glycol as a solvent, rather than water. It has been found that one can obtain crystalline pollucite by heating up to 350 degrees C in a high-pressure container (~15 MPa), mixed with montmorillonite - an abundant natural clay and ethylene glycol. It has been found that the reduction of the amount of water helps to achieve very high confinement rate in a reasonable time of few~20 h. This will be fairly important in processing contaminated water in the nuclear power plant. The influence of seawater has been also examined. PMID- 30302003 TI - Highly selective transition-metal-free transamidation of amides and amidation of esters at room temperature. AB - Amide chemistry has an essential role in the synthesis of high value molecules, such as pharmaceuticals, natural products, and fine chemicals. Over the past years, several examples of transamidation reactions have been reported. In general, transition-metal-based catalysts or harsh conditions are employed for these transformations due to unfavorable kinetics and thermodynamics of the process. Herein, we report a significant advance in this area and present the general method for transition-metal-free transamidation of amides and amidation of esters by highly selective acyl cleavage with non-nucleophilic amines at room temperature. In contrast to metal-catalyzed protocols, the method is operationally-simple, environmentally-friendly, and operates under exceedingly mild conditions. The practical value is highlighted by the synthesis of valuable amides in high yields. Considering the key role of amides in various branches of chemical science, we envision that this broadly applicable method will be of great interest in organic synthesis, drug discovery, and biochemistry. PMID- 30302004 TI - Long-term efficacy and duration of action of dexamethasone implant, in vitrectomised and non-vitrectomised eyes with persistent diabetic macular oedema. AB - PURPOSE: To evaluate the efficacy and duration of action of an intravitreal (dexamethasone (Ozurdex)) implant in vitrectomised and non-vitrectomised eyes with persistent diabetic macular oedema (DMO). METHODS: We retrospectively analysed the records for 18 eyes that had or had not been vitrectomised but required an intravitreal dexamethasone implant for DMO after a poor response to anti-vascular endothelial growth factor. Optical coherence tomography and visual acuity (VA) examinations were performed before and 1, 3 and 6 months after implantation. The six months following implantation constituted one treatment round; up to three rounds were studied. RESULTS: Ten of 18 eyes had undergone vitrectomy. Best-corrected visual acuity (BCVA) and central macular thickness (CMT) were significantly improved by months 1-3 after implantation of the Ozurdex device in all rounds of treatment. The BCVA and CMT deteriorated gradually after month 3 through to month 6 post implantation. There were no statistically significant differences between the vitrectomised and non-vitrectomised groups at any time point. When the implantation interval was <6 weeks from the end of each treatment round, the improvement in BCVA and CMT was obvious even after 18 months of treatment. CONCLUSIONS: Vitrectomy did not have a negative effect on the duration of action or efficacy of the Ozurdex implant in patients with persistent DMO. The implant started working from the first month after implantation regardless of whether vitrectomy had or had not been performed. The maximum functional and anatomic improvement was achieved in the first 3 months post implantation in all treatment rounds. PMID- 30302005 TI - Balance design for robust foliar nutrient diagnosis of "Prata" banana (Musa spp.). AB - The "Cavendish" and "Prata" subgroups represent respectively 47% and 24% of the world banana production. Compared to world average progressing from 10.6 to 20.6 t ha-1 between 1961 and 2016, and despite sustained domestic demand and the introduction of new cultivars, banana yield in Brazil has stagnated around 14.5 t ha-1 mainly due to nutrient and water mismanagement. "Prata" is now the dominant subgroup in N-E Brazil and is fertigated at high costs. Nutrient balances computed as isometric log-ratios (ilr) provide a comprehensive understanding of nutrient relationships in the diagnostic leaf at high yield level by combining raw concentration data. Although the most appropriate method for multivariate analysis of compositional balances may be less efficient due to non-normal data distribution and limited nutrient mobility in the plant, robustness of the nutrient balance approach could be improved using Box-Cox exponents assigned to raw foliar concentrations. Our objective was to evaluate the accuracy of nutrient balances to diagnose fertigated "Prata" orchards. The dataset comprised 609 observations on fruit yields and leaf tissue compositions collected from 2010 to 2016 in Ceara state, N-E Brazil. Raw nutrient concentration ranges were ineffective as diagnostic tool due to considerable overlapping of concentration ranges for low- and high-yielding subpopulations at cutoff yield of 40 Mg ha-1. Nutrient concentrations were combined into isometric log-ratios (ilr) and normalized by Box-Cox corrections between 0 and 1 which may also account for restricted nutrient transfer from leaf to fruit. Despite reduced ilr skewness, Box-Cox coefficients did not improve model robustness measured as the accuracy of the Cate-Nelson partition between yield and the multivariate distance across ilr values. Sensitivity was 94%, indicating that low yields are attributable primarily to nutrient imbalance. There were 148 false-positive specimens (high yield despite nutrient imbalance) likely due to suboptimal nutrition, contamination, or luxury consumption. The profitability of "Prata" orchards could be enhanced by rebalancing nutrients using ilr standards with no need for Box-Cox correction. PMID- 30302006 TI - A mechanoelectrical mechanism for detection of sound envelopes in the hearing organ. AB - To understand speech, the slowly varying outline, or envelope, of the acoustic stimulus is used to distinguish words. A small amount of information about the envelope is sufficient for speech recognition, but the mechanism used by the auditory system to extract the envelope is not known. Several different theories have been proposed, including envelope detection by auditory nerve dendrites as well as various mechanisms involving the sensory hair cells. We used recordings from human and animal inner ears to show that the dominant mechanism for envelope detection is distortion introduced by mechanoelectrical transduction channels. This electrical distortion, which is not apparent in the sound-evoked vibrations of the basilar membrane, tracks the envelope, excites the auditory nerve, and transmits information about the shape of the envelope to the brain. PMID- 30302007 TI - Changing patterns of adult asthma incidence: results from the National Health Insurance Service-National Sample Cohort (NHIS-NSC) database in Korea. AB - This study was conducted to assess the changes in the annual incidence of adult asthma in Korea where the prevalence of asthma had increased steadily in recent decades. A population-based cohort study was conducted using the National Health Insurance Service-National Sample Cohort (NHIS-NSC), which consisted of 746,816 adults aged >20 years between 2004 and 2012. Asthma was defined by two or more physician claims on the basis of a primary diagnostic code for asthma and administration of asthma medications within 1 year. The incidence rates and annual percent change were calculated, and the influence of age and sex on the incidence rates was studied. The annual asthma incidence increased from 3.63 in 2004 to 6.07 per 1,000 person-years in 2008. Since 2008, the asthma incidence did not change significantly. The asthma incidence was higher in women than in men throughout the study periods (p < 0.001) and higher in older than younger age groups (p < 0.001). The asthma incidence did not change in all ages since 2008, except for the 20 s who showed a steady increase. The incidence of asthma in adults reached plateau in Korea, which is consistent with the results from studies in other countries. PMID- 30302008 TI - Templated replication (or lack thereof) under prebiotically pertinent conditions. AB - Accurate replication of encoded information would have been crucial for the formation and propagation of functional ribozymes during the early evolution of life. Studies aimed at understanding prebiotically pertinent nonenzymatic reactions have predominantly used activated nucleotides. However, the existence of concentrated pools of activated monomers on prebiotic Earth is debatable. In this study, we explored the feasibility of nonenzymatic copying reactions using the more prebiotically relevant 5'-nucleoside monophosphates (5'-NMP). These reactions, involving a 20-mer primer, were performed in the presence of amphiphiles, under volcanic geothermal conditions. Interestingly, the extended primer was not comparable to the expected full length 21-mer product. Our results suggest loss of the nitrogenous base in the extended primer. This phenomenon persisted even after lowering the temperature and when different rehydration solutions were used. We envisage that the loss of the informational moiety on the incoming 5'-NMP, might be occurring during addition of this monomer to the pre existing oligomer. Significantly, when 5'-ribose monophosphate was used, multiple additions to the aforementioned primer were observed that resulted in hybrid polymers. Such hybrid oligomers could have been important for exploring a vast chemical space of plausible alternate nucleobases, thus having important implications for the origin of primitive informational polymers. PMID- 30302009 TI - Febrile Temperature Elevates the Expression of Phosphatidylserine on Plasmodium falciparum (FCR3CSA) Infected Red Blood Cell Surface Leading to Increased Cytoadhesion. AB - During the asexual intra-erythrocytic cycle, Plasmodium (P.) falciparum exports parasitic proteins to the surface of infected red blood cells (iRBCs) facilitating its cytoadhesion to various endothelial host receptors. This adhesive behavior is a critical contributor towards disease manifestation. However, little is known about the influence of recurring elevated temperature - a common symptom of the malaria infection - on the adhesive properties of iRBCs to endothelial receptors. To address this, we performed dual-micropipette step pressure technique between P. falciparum (strain FCR3CSA) iRBCs and Chinese Hamster Ovary cells expressing Chondroitin sulfate A (CHO-CSA) after transient iRBCs incubation at febrile temperatures which revealed increase in adhesion parameters. Furthermore, flow cytometry analysis revealed an increase in phosphatidylserine (PS) expression on the iRBC surface following exposure to febrile temperature. The adhesion between iRBCs and CHO-CSA cells was remarkably reduced in presence of soluble Annexin V, indicating the mediation of PS on the adhesion events. Our results suggest that elevated PS recruitment on iRBC under thermally stressed conditions contributes to the increased adhesive behavior of iRBCs CSA-binding phenotype to CHO-CSA. PMID- 30302010 TI - PLA2G6-associated neurodegeneration presenting as a complicated form of hereditary spastic paraplegia. AB - PLA2G6-associated neurodegeneration (PLAN) comprises heterogeneous neurodegenerative disorders, including infantile neuroaxonal dystrophy, neurodegeneration with brain iron accumulation 2B, and Parkinson disease 14 (PARK14). In addition, very recently, PLA2G6 mutations have been reported to represent a phenotype of hereditary spastic paraplegia (HSP). In this study, we screened 383 HSP families to clarify the frequency of PLA2G6 mutations in the Japan Spastic Paraplegia Research Consortium, and revealed the clinical characteristics of HSP with PLA2G6 mutations. We found three families with compound heterozygous mutations of the PLA2G6 gene, c.517 C > T/c.1634A > G, c.662 T > C/c.991 G > T, and c.1187-2 A > G/c.1933C > T, and one family with a homozygous mutation of the PLA2G6 gene, c.1904G > A/c.1904G > A. All three families with compound heterozygous mutations presented a uniform phenotype of a complicated form of HSP with infantile/child-onset spastic paraplegia, cerebellar ataxia, and mental retardation. On the other hand, the family with a homozygous mutation presented a late-onset complicated form of HSP with parkinsonism. This study may extend the clinical and genetic findings for PLAN. PMID- 30302011 TI - Structural Rearrangements Maintain the Glycan Shield of an HIV-1 Envelope Trimer After the Loss of a Glycan. AB - The HIV-1 envelope (Env) glycoprotein is the primary target of the humoral immune response and a critical vaccine candidate. However, Env is densely glycosylated and thereby substantially protected from neutralisation. Importantly, glycan N301 shields V3 loop and CD4 binding site epitopes from neutralising antibodies. Here, we use molecular dynamics techniques to evaluate the structural rearrangements that maintain the protective qualities of the glycan shield after the loss of glycan N301. We examined a naturally occurring subtype C isolate and its N301A mutant; the mutant not only remained protected against neutralising antibodies targeting underlying epitopes, but also exhibited an increased resistance to the VRC01 class of broadly neutralising antibodies. Analysis of this mutant revealed several glycans that were responsible, independently or through synergy, for the neutralisation resistance of the mutant. These data provide detailed insight into the glycan shield's ability to compensate for the loss of a glycan, as well as the cascade of glycan movements on a protomer, starting at the point mutation, that affects the integrity of an antibody epitope located at the edge of the diminishing effect. These results present key, previously overlooked, considerations for HIV-1 Env glycan research and related vaccine studies. PMID- 30302012 TI - Peptide-oligonucleotide conjugates exhibiting pyrimidine-X cleavage specificity efficiently silence miRNA target acting synergistically with RNase H. AB - Taking into account the important role of miRNA in carcinogenesis, oncogenic miRNAs are attractive molecules for gene-targeted therapy. Here, we developed a novel series of peptide-oligonucleotide conjugates exhibiting ribonuclease activity targeted to highly oncogenic miRNAs miR-21 and miR-17. When designing the conjugates, we enhanced both nuclease resistance of the targeted oligodeoxyribonucleotide by introducing at its 3'-end mini-hairpin structure displaying high thermostability and robustness against nuclease digestion and the efficiency of its functioning by attachment of the catalytic construction (amide)NH2-Gly(ArgLeu)4-TCAA displaying ribonuclease activity to its 5'-end. Designed miRNases efficiently cleaved miRNA targets, exhibiting Pyr-X specificity, and cleavage specificity had strong dependence on the miRNA sequence in the site of peptide location. In vitro, designed miRNases do not prevent cleavage of miRNA bound with the conjugate by RNase H, and more than an 11-fold enhancement of miRNA cleavage by the conjugate is observed in the presence of RNase H. In murine melanoma cells, miRNase silences mmu-miR-17 with very high efficiency as a result of miR-17 cleavage by miRNase and by recruited RNase H. Thus, miRNases provide a system of double attack of the miRNA molecules, significantly increasing the efficiency of miRNA downregulation in the cells in comparison with antisense oligonucleotide. PMID- 30302014 TI - Verifying locations of sources of historical environmental releases of dioxin like compounds in the U.S.: implications for exposure assessment and epidemiologic inference. AB - Polychlorinated dibenzo-p-dioxin and dibenzofuran (PCDD/F) emissions from industrial sources contaminate the surrounding environment. Proximity-based exposure surrogates assume accuracy in the location of PCDD/F sources, but locations are not often verified. We manually reviewed locations (i.e., smokestack geo-coordinates) in a historical database of 4478 PCDD/F-emitting facilities in 2009 and 2016. Given potential changes in imagery and other resources over this period, we re-reviewed a random sample of 5% of facilities (n = 240) in 2016. Comparing the original and re-review of this sample, we evaluated agreement in verification (location confirmed or not) and distances between verified locations (verification error), overall and by facility type. Using the verified location from re-review as a gold standard, we estimated the accuracy of proximity-based exposure metrics and epidemiologic bias. Overall agreement in verification was high (>84%), and verification errors were small (median = 84 m) but varied by facility type. Accuracy of exposure classification (>=1 facility within 5 km) for a hypothetical study population also varied by facility type (sensitivity: 69-96%; specificity: 95-98%). Odds ratios were attenuated 11-69%, with the largest bias for rare facility types. We found good agreement between reviews of PCDD/F source locations, and that exposure prevalence and facility type may influence associations with exposures derived from this database. Our findings highlight the need to consider location error and other contextual factors when using proximity-based exposure metrics. PMID- 30302013 TI - Porcine Reproductive and Respiratory Syndrome Virus strains with Higher Virulence Cause Marked Protein Profile Changes in MARC-145 Cells. AB - Porcine reproductive and respiratory syndrome is an infectious disease that causes serious economic losses to the swine industry worldwide. To better understand the pathogenesis of the porcine reproductive and respiratory syndrome virus (PRRSV), three PRRSV strains with different molecular markers and virulence were used to infect MARC-145 cells. A total of 1804 proteins were identified, and 233 altered proteins and 72 signaling pathways involved in the proteomic profiling of virus-infected MARC-145 cells increased with the virulence of the PRRSV strain. The three types of viral strains shared a common pathway-the electron transport reaction in mitochondria-in the infected-MARC-145 cells. Moreover, the antisense pathway was the most variable of all significant signaling pathways for the highly virulent SX-1 strain, indicating that this unique pathway may be connected to the high virulence of the SX-1 strain. Our study is the first attempt to provide a proteome profile of MARC-145 cells infected with PRRSV strains with different virulence, and these findings will facilitate a deep understanding of the interactions between this virus and its host. PMID- 30302015 TI - Alleviation of impaired reactivity in the corpus cavernosum of STZ-diabetic rats by slow-release H2S donor GYY4137. AB - GYY4137 is a novel hydrogen sulfide (H2S) releasing molecule with vasodilator activity. The objectives of this study were to investigate: (1) the pharmacological effect of GYY4137 on the reactivity of the corpus cavernosum (CC) from normal and diabetic rats; (2) the contribution of ATP-sensitive potassium (K ATP) channels and nitric oxide (NO) pathway; (3) the reactivity to vasoactive agonists following ex vivo incubation of the diabetic rat CC with GYY4137. Longitudinal strips of CC from control and diabetic male Sprague-Dawley (SD) rats (n = 5-6 animals per group) were suspended in organ-baths. Responses to GYY4137, carbachol, or phenylephrine (PE) were determined by measurement of changes in isometric tension. The effects of acute incubation of the CC strips with L-NAME (NO synthase inhibitor) or glibenclamide (K-ATP channel inhibitor) on the relaxant responses to GYY4137 were examined. The effect of ex vivo incubation with GYY4137 (10-5 M) on the responses of CC to carbachol or PE was evaluated. We found that GYY4137 provoked relaxation in the CC strips, which was significantly reduced in the presence of L-NAME or glibenclamide. Ex vivo incubation of diabetic CC with GYY4137 resulted in a significant improvement in the vascular responses to the added agonists. We conclude that GYY4137 is a relaxant agonist in SD rats CC, and the response is mediated, at least in part, by NO and K-ATP channels. Brief incubation of diabetic CC with GYY4137 markedly improved the impaired vascular reactivity, thus raising the question whether chronic in vivo treatment of diabetic animals with GYY4137 would have any protective effect, which is worth further investigation. PMID- 30302016 TI - Nitazoxanide, an antiprotozoal drug, inhibits late-stage autophagy and promotes ING1-induced cell cycle arrest in glioblastoma. AB - Glioblastoma is the most common and aggressive primary brain tumor in adults. New drug design and development is still a major challenge for glioma treatment. Increasing evidence has shown that nitazoxanide, an antiprotozoal drug, has a novel antitumor role in various tumors and exhibits multiple molecular functions, especially autophagic regulation. However, whether nitazoxanide-associated autophagy has an antineoplastic effect in glioma remains unclear. Here, we aimed to explore the underlying molecular mechanism of nitazoxanide in glioblastoma. Our results showed that nitazoxanide suppressed cell growth and induced cell cycle arrest in glioblastoma by upregulating ING1 expression with a favorable toxicity profile. Nitazoxanide inhibited autophagy through blockage of late-stage lysosome acidification, resulting in decreased cleavage of ING1. A combination with chloroquine or Torin1 enhanced or impaired the chemotherapeutic effect of nitazoxanide in glioblastoma cells. Taken together, these findings indicate that nitazoxanide as an autophagy inhibitor induces cell cycle arrest in glioblastoma via upregulated ING1 due to increased transcription and decreased post translational degradation by late-stage autophagic inhibition. PMID- 30302017 TI - Using long term mortality to determine which perioperative risk factors of mortality following hip and knee replacement may be causal. AB - Observational studies have identified surgical factors that are associated with a reduced risk of mortality after joint replacement. It is not clear whether these are causal or reflect patient selection. Data on the first primary hip (n = 424,156) and knee replacements (n = 469,989) performed for osteoarthritis in the National Joint Registry were analysed. Flexible parametric survival modelling was used to determine if risk factors for mortality in the perioperative period persisted. To explore selection bias, standardised mortality ratios were calculated for all-cause, respiratory and smoking related cancer mortality using population rates. Selection was apparent for hip resurfacing, combined spinal and general anaesthetic and unicondylar knee implants; reduced mortality was observed for many years for both all and other causes of mortality with a waning effect. Mechanical thromboprophylaxis was also suggestive of selection although patients receiving aspirin had sustained reduced mortality, possibly due to to a cardioprotective effect. Posterior approach for hips was ambiguous with a possible causal component. Spinal anaesthesia was suggestive of a causal effect. We are reliant on observational data when it is not feasible to undertake randomised trials. Our approach of looking at long term mortality risks for perioperative interventions provides further insights to differentiate causal interventions from selection. We recommend the use of aspirin chemothromboprophylaxis, the posterior approach and spinal anaesthetic in total hip replacement due to the apparent causal effect on reduced mortality. PMID- 30302019 TI - Tracking Tumor Colonization in Xenograft Mouse Models Using Accelerator Mass Spectrometry. AB - Here we introduce an Accelerator Mass Spectrometry (AMS)-based high precision method for quantifying the number of cancer cells that initiate metastatic tumors, in xenograft mice. Quantification of 14C per cell prior to injection into animals, and quantification of 14C in whole organs allows us to extrapolate the number of cancer cells available to initiate metastatic tumors. The 14C labeling was optimized such that 1 cancer cell was detected among 1 million normal cells. We show that ~1-5% of human cancer cells injected into immunodeficient mice form subcutaneous tumors, and even fewer cells initiate metastatic tumors. Comparisons of metastatic site colonization between a highly metastatic (PC3) and a non metastatic (LnCap) cell line showed that PC3 cells colonize target tissues in greater quantities at 2 weeks post-delivery, and by 12 weeks post-delivery no 14C was detected in LnCap xenografts, suggesting that all metastatic cells were cleared. The 14C-signal correlated with the presence and the severity of metastatic tumors. AMS measurements of 14C-labeled cells provides a highly sensitive, quantitative assay to experimentally evaluate metastasis and colonization of target tissues in xenograft mouse models. This approach can potentially be used to evaluate tumor aggressiveness and assist in making informed decisions regarding treatment. PMID- 30302018 TI - The disparate effects of bacteriophages on antibiotic-resistant bacteria. AB - Faced with the crisis of multidrug-resistant bacteria, bacteriophages, viruses that infect and replicate within bacteria, have been reported to have both beneficial and detrimental effects with respect to disease management. Bacteriophages (phages) have important ecological and evolutionary impacts on their bacterial hosts and have been associated with therapeutic use to kill bacterial pathogens, but can lead to the transmission of antibiotic resistance. Although the process known as transduction has been reported for many bacterial species by classic and modern genetic approaches, its contribution to the spread of antibiotic resistance in nature remains unclear. In addition, detailed molecular studies have identified phages residing in bacterial genomes, revealing unexpected interactions between phages and their bacterial hosts. Importantly, antibiotics can induce the production of phages and phage-encoded products, disseminating these viruses and virulence-related genes, which have dangerous consequences for disease severity. These unwanted side-effects of antibiotics cast doubt on the suitability of some antimicrobial treatments and may require new strategies to prevent and limit the selection for virulence. Foremost among these treatments is phage therapy, which could be used to treat many bacterial infectious diseases and confront the pressing problem of antibiotic resistance in pathogenic bacteria. This review discusses the interactions between bacteriophages, antibiotics, and bacteria and provides an integrated perspective that aims to inspire the development of successful antibacterial therapies. PMID- 30302020 TI - Transformation of amorphous calcium phosphate to bone-like apatite. AB - Mineralisation of calcium phosphates in bone has been proposed to proceed via an initial amorphous precursor phase which transforms into nanocrystalline, carbonated hydroxyapatite. While calcium phosphates have been under intense investigation, the exact steps during the crystallisation of spherical amorphous particles to platelet-like bone apatite are unclear. Herein, we demonstrate a detailed transformation mechanism of amorphous calcium phosphate spherical particles to apatite platelet-like crystals, within the confined nanodomains of a bone-inspired nanocomposite. The transformation is initiated under the presence of humidity, where nanocrystalline areas are formed and crystallisation advances via migration of nanometre sized clusters by forming steps at the growth front. We propose that such transformation is a possible crystallisation mechanism and is characteristic of calcium phosphates from a thermodynamic perspective and might be unrelated to the environment. Our observations provide insight into a crucial but unclear stage in bone mineralisation, the origins of the nanostructured, platelet-like bone apatite crystals. PMID- 30302021 TI - Involvement of anterior and posterior corneal surface area imbalance in the pathological change of keratoconus. AB - Keratoconus (KC) is an ectatic disorder with a high prevalence rate. However, the exact cause of the disease and possible underlying mechanisms of development remain unclear. In this present study, we aimed to investigate the anterior and the posterior corneal surface area in normal, forme fruste keratoconus (FFKC), and keratoconic eyes (as a reference group) using anterior segment optical coherence tomography (AS-OCT) in order to assess the pathological change of KC. The surface areas of the anterior or posterior cornea, and the anterior-posterior (As/Ps) ratio of corneal surface area, were measured at the central 5.0 mm-, 6.0 mm-, and 7.0 mm-diameter areas via AS-OCT, and a comparison between the normal eyes and FFKC eyes was then performed using the Mann-Whitney U test. The posterior surface area at the central 5.0 mm areas in the FFKC eyes (20.430 mm2) and KC eyes (20.917 mm2) seemed to become larger than that of normal eyes (20.389 mm2) (normal vs FFKC; P = 0.06). Moreover, the As/Ps of the corneal surface area in the FFKC eyes (0.986) and the KC eyes (0.976) was significantly smaller than that of the normal eyes (0.988) (normal vs FFKC; P < 0.01). Anterior and posterior corneal surface area imbalance may reflect keratoconic eyes at the early stage of the disease. PMID- 30302022 TI - An HER3-targeting antibody-drug conjugate incorporating a DNA topoisomerase I inhibitor U3-1402 conquers EGFR tyrosine kinase inhibitor-resistant NSCLC. AB - EGFR tyrosine kinase inhibitors (TKIs) are standard therapy for EGFR-mutant non small cell lung cancer (NSCLC); however, these tumours eventually acquire chemoresistance. U3-1402 is an anti-HER3 antibody-drug conjugate with a novel topoisomerase I inhibitor, DXd. In the current study, we evaluated the anticancer efficacy of U3-1402 in EGFR-mutant NSCLC cells with acquired resistance to EGFR TKIs. HCC827GR5 and PC9AZDR7 are EGFR-TKI-resistant clones for gefitinib and osimertinib, respectively. U3-1402 alone or in combination with the EGFR-TKI erlotinib demonstrated potent anticancer efficacy in HCC827GR5 cells using an in vitro growth inhibition assay and in vivo xenograft mouse model. U3-1402 induced apoptosis in HCC827GR5 cells accompanying phosphorylation of histone H2A.X, a marker of DNA damage, but did not block HER3/PI3K/AKT signalling. Further, we found using flow cytometry that the cell surface HER3 expression level in HCC827GR5 cells was twice that found in HCC827 cells, indicating internalization of U3-1402 was increased in resistant cells. In addition, administration of U3 1402 notably repressed growth of EGFR-TKI osimertinib-resistant PC9AZDR7 xenograft tumours, and that PC9AZDR7 cells expressed five times greater cell surface HER3 than PC9 cells. Furthermore, using immunofluorescent microscopy, HER3 was observed predominantly in the nucleus of PC9 cells, but was localized in the cytoplasm of PC9AZDR7 cells. This finding indicates that altered trafficking of the HER3-U3-1402 complex may accelerate linker payload cleavage by cytoplasmic lysosomal enzymes, resulting in DNA damage. Our results indicate that administration of U3-1402 alone or in combination with an EGFR-TKI may have potential as a novel therapy for EGFR-TKI-resistant EGFR-mutant NSCLC. PMID- 30302023 TI - The antioxidant transcription factor Nrf2 modulates the stress response and phenotype of malignant as well as premalignant pancreatic ductal epithelial cells by inducing expression of the ATF3 splicing variant DeltaZip2. AB - Pancreatic ductal adenocarcinoma (PDAC) exhibits one of the worst survival rates of all cancers. While death rates show declining trends in the majority of cancers, PDAC registers rising rates. Based on the recently described crosstalk between TGF-beta1 and Nrf2 in the PDAC development, the involvement of ATF3 and its splice variant DeltaZip2 in TGF-beta1- and Nrf2-driven pancreatic tumorigenesis was investigated. As demonstrated here, PDAC (Panc1, T3M4) cells or premalignant H6c7 pancreatic ductal epithelial cells differentially express DeltaZip2- and ATF3, relating to stronger Nrf2 activity seen in Panc1 cells and TGF-beta1 activity in T3M4 or H6c7 cells, respectively. Treatment with the electrophile/oxidative stress inducer tBHQ or the cytostatic drug gemcitabine strongly elevated DeltaZip2 expression in a Nrf2-dependent fashion. The differential expression of ATF3 and DeltaZip2 in response to Nrf2 and TGF-beta1 relates to differential ATF3-gene promoter usage, giving rise of distinct splice variants. Nrf2-dependent DeltaZip2 expression confers resistance against gemcitabine-induced apoptosis, only partially relating to interference with ATF3 and its proapoptotic activity, e.g., through CHOP-expression. In fact, DeltaZip2 autonomously activates expression of cIAP anti-apoptotic proteins. Moreover, DeltaZip2 favors and ATF3 suppresses growth and clonal expansion of PDAC cells, again partially independent of each other. Using a Panc1 tumor xenograft model in SCID-beige mice, the opposite activities of ATF3 and DeltaZip2 on tumor-growth and chemoresistance were verified in vivo. Immunohistochemical analyses confirmed DeltaZip2 and Nrf2 coexpression in cancerous and PanIN structures of human PDAC and chronic pancreatitis tissues, respectively, which to some extent was reciprocal to ATF3 expression. It is concluded that depending on selective ATF3 gene promoter usage by Nrf2, the DeltaZip2 expression is induced in response to electrophile/oxidative (here through tBHQ) and xenobiotic (here through gemcitabine) stress, providing apoptosis protection and growth advantages to pancreatic ductal epithelial cells. This condition may substantially add to pancreatic carcinogenesis driven by chronic inflammation. PMID- 30302024 TI - Superiority of SpiroZin2 Versus FluoZin-3 for monitoring vesicular Zn2+ allows tracking of lysosomal Zn2+ pools. AB - Small-molecule fluorescent probes are powerful and ubiquitous tools for measuring the concentration and distribution of analytes in living cells. However, accurate characterization of these analytes requires rigorous evaluation of cell-to-cell heterogeneity in fluorescence intensities and intracellular distribution of probes. In this study, we perform a parallel and systematic comparison of two small-molecule fluorescent vesicular Zn2+ probes, FluoZin-3 AM and SpiroZin2, to evaluate each probe for measurement of vesicular Zn2+ pools. Our results reveal that SpiroZin2 is a specific lysosomal vesicular Zn2+ probe and affords uniform measurement of resting Zn2+ levels at the single cell level with proper calibration. In contrast, FluoZin-3 AM produces highly variable fluorescence intensities and non-specifically localizes in the cytosol and multiple vesicular compartments. We further applied SpiroZin2 to lactating mouse mammary epithelial cells and detected a transient increase of lysosomal free Zn2+ at 24-hour after lactation hormone treatment, which implies that lysosomes play a role in the regulation of Zn2+ homeostasis during lactation. This study demonstrates the need for critical characterization of small-molecule fluorescent probes to define the concentration and localization of analytes in different cell populations, and reveals SpiroZin2 to be capable of reporting diverse perturbations to lysosomal Zn2+. PMID- 30302025 TI - AIMP3 Deletion Induces Acute Radiation Syndrome-like Phenotype in Mice. AB - Genomes are mostly protected from constant DNA-damaging threats, either internal or external, which ultimately sustain the organism. Herein, we report that AIMP3, a previously demonstrated tumour suppressor, plays an essential role in maintaining genome integrity in adult mice. Upon induction of the temporal systemic deletion of AIMP3 by tamoxifen in adult mice, the animals developed an acute radiation syndrome-like phenotype, typified by scleroderma, hypotrophy of haematopoietic cells and organs, and intestinal failure. Induction of gammaH2AX, an early marker of DNA double-strand breaks, was observed in the spleen, intestine, and the highly replicating embryonic cortex. In addition, sub-lethal irradiation of AIMP3 mKO mice dramatically affected organ damage and survival. Using isolated MEFs from conditional KO mice or AIMP3 knockdown cells, we confirmed the presence of spontaneously occurring DNA double-strand breaks by COMET assay and gammaH2AX induction. Furthermore, gammaH2AX removal was delayed, and homologous DNA repair activity was significantly reduced. Reduction of RPA foci formation and subsequent Rad51 foci formation probably underlie the significant reduction in homologous recombination activity in the absence of AIMP3. Together, our data demonstrate that AIMP3 plays a role in genome stability through the DNA repair process. PMID- 30302026 TI - Carbon stocks and accumulation rates in Red Sea seagrass meadows. AB - Seagrasses play an important role in climate change mitigation and adaptation, acting as natural CO2 sinks and buffering the impacts of rising sea level. However, global estimates of organic carbon (Corg) stocks, accumulation rates and seafloor elevation rates in seagrasses are limited to a few regions, thus potentially biasing global estimates. Here we assessed the extent of soil Corg stocks and accumulation rates in seagrass meadows (Thalassia hemprichii, Enhalus acoroides, Halophila stipulacea, Thalassodendrum ciliatum and Halodule uninervis) from Saudi Arabia. We estimated that seagrasses store 3.4 +/- 0.3 kg Corg m-2 in 1 m-thick soil deposits, accumulated at 6.8 +/- 1.7 g Corg m-2 yr-1 over the last 500 to 2,000 years. The extreme conditions in the Red Sea, such as nutrient limitation reducing seagrass growth rates and high temperature increasing soil respiration rates, may explain their relative low Corg storage compared to temperate meadows. Differences in soil Corg storage among habitats (i.e. location and species composition) are mainly related to the contribution of seagrass detritus to the soil Corg pool, fluxes of Corg from adjacent mangrove and tidal marsh ecosystems into seagrass meadows, and the amount of fine sediment particles. Seagrasses sequester annually around 0.8% of CO2 emissions from fossil fuels by Saudi Arabia, while buffering the impacts of sea level rise. This study contributes data from understudied regions to a growing dataset on seagrass carbon stocks and sequestration rates and further evidences that even small seagrass species store Corg in coastal areas. PMID- 30302027 TI - An innovative flow cytometry method to screen human scFv-phages selected by in vivo phage-display in an animal model of atherosclerosis. AB - Atherosclerosis is a chronic, progressive inflammatory disease that may develop into vulnerable lesions leading to thrombosis. This pathology is characterized by the deposition of lipids within the arterial wall and infiltration of immune cells leading to amplification of inflammation. Nowadays there is a rising interest to assess directly the molecular and cellular components that underlie the clinical condition of stroke and myocardial infarction. Single chain fragment variable (scFv)-phages issuing from a human combinatorial library were selected on the lesions induced in a rabbit model of atherosclerosis after three rounds of in vivo phage display. We further implemented a high-throughput flow cytometry method on rabbit protein extracts to individually test one thousand of scFv phages. Two hundred and nine clones were retrieved on the basis of their specificity for atherosclerotic proteins. Immunohistochemistry assays confirmed the robustness of the designed cytometry protocol. Sequencing of candidates demonstrated their high diversity in VH and VL germline usage. The large number of candidates and their diversity open the way in the discovery of new biomarkers. Here, we successfully showed the capacity of combining in vivo phage display and high-throughput cytometry strategies to give new insights in in vivo targetable up-regulated biomarkers in atherosclerosis. PMID- 30302028 TI - Molecular signalling towards mitochondrial breakdown is enhanced in skeletal muscle of patients with chronic obstructive pulmonary disease (COPD). AB - Loss of skeletal muscle mitochondrial oxidative capacity is well-established in patients with COPD, but the role of mitochondrial breakdown herein is largely unexplored. Currently, we studied if mitochondrial breakdown signalling is increased in skeletal muscle of COPD patients and associates with the loss of mitochondrial content, and whether it is affected in patients with iron deficiency (ID) or systemic inflammation. Therefore, mitophagy, autophagy, mitochondrial dynamics and content markers were analysed in vastus lateralis biopsies of COPD patients (N = 95, FEV1% predicted: 39.0 [31.0-53.6]) and healthy controls (N = 15, FEV1% predicted: 112.8 [107.5-125.5]). Sub-analyses were performed on patients stratified by ID or C-reactive protein (CRP). Compared with controls, COPD patients had lower muscle mitochondrial content, higher BNIP3L and lower FUNDC1 protein, and higher Parkin protein and gene-expression. BNIP3L and Parkin protein levels inversely correlated with mtDNA/gDNA ratio and FEV1% predicted. ID-COPD patients had lower BNIP3L protein and higher BNIP3 gene expression, while high CRP patients had higher BNIP3 and autophagy-related protein levels. In conclusion, our data indicates that mitochondrial breakdown signalling is increased in skeletal muscle of COPD patients, and is related to disease severity and loss of mitochondrial content. Moreover, systemic inflammation is associated with higher BNIP3 and autophagy-related protein levels. PMID- 30302029 TI - Morphological changes, nitric oxide production, and phagocytosis are triggered in vitro in microglia by bloodstream forms of Trypanosoma brucei. AB - The flagellated parasite Trypanosoma brucei is the causative agent of Human African Trypanosomiasis (HAT). By a mechanism not well understood yet, trypanosomes enter the central nervous system (CNS), invade the brain parenchyma, and cause a fatal encephalopathy if is not treated. Trypanosomes are fast dividing organisms that, without any immune response, would kill the host in a short time. However, infected individuals survive either 6-12 months or more than 3 years for the acute and chronic forms, respectively. Thus, only when the brain defense collapses a lethal encephalopathy will occur. Here, we evaluated interactions between trypanosomes and microglial cells, which are the primary immune effector cells within the CNS. Using co-cultures of primary microglia and parasites, we found clear evidences of trypanosome phagocytosis by microglial cells. Microglia activation was also evident; analysis of its ultrastructure showed changes that have been reported in activated microglia undergoing oxidative stress caused by infections or degenerative diseases. Accordingly, an increase of the nitric oxide production was detected in supernatants of microglia/parasite co-cultures. Altogether, our results demonstrate that microglial cells respond to the presence of the parasite, leading to parasite's engulfment and elimination. PMID- 30302030 TI - Effects of PTH on bone composition. PMID- 30302031 TI - Pelvic sexual dimorphism among species monomorphic in body size: relationship to relative newborn body mass. AB - Females have larger pelves than males among eutherians to mitigate obstetrical difficulty. This study addresses 3 issues concerning pelvic sexual dimorphism using 8 species that are sexually monomorphic in nonpelvic size: Aotus azarae , Castor canadensis , Dasypus novemcinctus , Hylobates lar , Saguinus geoffroyi , Sciurus carolinensis , Sylvilagus floridanus , and Urocyon cinereoargenteus . Using published data to compute the index of relative newborn body mass (RNBM = [newborn body mass/adult female body mass]100%) for 266 eutherian species, A. azarae , H. lar , and S. geoffroyi are characterized as giving birth to relatively large newborns and the other 5 species as giving birth to relatively small newborns. The 3 issues are, compared to species giving birth to relatively small newborns, whether species that give birth to relatively large newborns have 1) higher magnitude of pelvic sexual size dimorphism (SSD), 2) lower prevalence of pelvic joint fusion, and 3) dissociation between pelvic and nonpelvic sizes. Nine measures of the pelvis were taken, and fusion of interpubic and sacroiliac joints was observed. Species grouped by high and low RNBM do not differ significantly in magnitude of SSD of pelvic inlet circumference. Species with high RNBM have significantly lower prevalence of interpubic joint fusion than those with low RNBM. Sexes do not differ in their multiple correlation coefficients between inlet circumference and nonpelvic body size in 7 of 8 species. Results suggest that 1) there are multiple anatomical pathways for pelvic obstetrical sufficiency, 2) an unfused interpubic joint is obstetrically advantageous, and 3) relative newborn size does not change the association between pelvic and nonpelvic size in females and males. PMID- 30302032 TI - Limited and fitness-neutral effects of resource heterogeneity on sociality in a communally rearing rodent. AB - Contrasting scenarios have been proposed to explain how resource heterogeneity influences group living or sociality. First, sociality may result from individuals in larger groups attaining net fitness benefits by monopolizing access to resources ("resource-defense" hypothesis). Second, sociality may be the fitness-neutral outcome of multiple individuals using a territory with sufficient resources to sustain a group of conspecifics ("resource-dispersion" hypothesis). While previous studies have tended to support the resource-dispersion hypothesis, these analyses have typically examined only 1 or a few predictions, making it difficult to distinguish between the 2 alternatives. We conducted a 4-year field study of Octodon degus to quantify the effects of spatial heterogeneity in food and refuge distributions on group size and 2 components of reproductive success (per capita number of offspring, offspring survival) in this plural breeding and communal rearing rodent. We found only a small effect of heterogeneity of food resources on group size; the effect food resource distribution on group territory size varied across years. Group size did not vary with spatial variation in group territory size and quality. Importantly, there was no covariation between group size and quality of an individual's territory (i.e., a measure of individual access to resources), or between this measure of territory quality and reproductive success, implying no resource-based benefits to social degus. Overall, our results were more consistent with fitness-neutral relationships among spatial heterogeneity of resources, sociality, and territory size. The resource-dispersion hypothesis, however, did not provide a complete explanation for degu socioecology. Se han propuesto distintas hipotesis para explicar como la heterogeneidad de los recursos afecta la vida en grupos, o sociabilidad. Esta puede surgir en situaciones donde individuos en grupos grandes se benefician al monopolizar el acceso a recursos (hipotesis de defensa de recursos). Por otra parte, la vida en grupos tambien puede ser el resultado neutro (en terminos de adecuacion) de individuos que comparten un territorio con recursos suficientes (hipotesis de dispersion de recursos). Aunque algunos estudios previos han validado la hipotesis de dispersion de recursos, estos solo han evaluado un numero limitado de las predicciones de esta hipotesis, lo que ha dificultado distinguir entre esta y otras hipotesis alternativas. Durante un estudio de 4 anos cuantificamos los efectos de la heterogeneidad espacial de alimento y distribucion de refugios sobre el tamano de grupo y dos componentes del exito reproductivo (numero per capita de crias, supervivencia de las crias) en Octodon degus. Se registraron efectos relativamente pequenos de la heterogeneidad espacial del alimento sobre el tamano de grupo, y variables entre anos sobre el tamano del territorio de cada grupo. El tamano de grupo no fue afectado por la variacion espacial en el tamano y calidad del territorio de los grupos. No se registro co-variacion entre el tamano de los grupos y la calidad del territorio de cada individuo (una medida individual del acceso a recursos), o entre la calidad del territorio individual y el exito reproductivo, lo que sugiere ausencia de beneficios derivados del uso social de recursos en degus. En general, los resultados fueron mas consistentes con un escenario de efectos neutros de la heterogeneidad espacial de recursos sobre la sociabilidad. Sin embargo, la hipotesis de dispersion de recursos no explico el conjunto de efectos (o su ausencia) asociados a la socioecologia del degu. PMID- 30302033 TI - Proprietary Herbal Extract Downregulates the Gene Expression of IL-1alpha in HaCaT Cells: Possible Implications Against Nonscarring Alopecia. AB - Background: Currently while, topical minoxidil and oral finasteride are the only medications approved in androgenetic alopecia (AGA), the cause oriented treatment and immunsupressive treatment are being performed in telogen effluvium (TE) and alopecia areata (AA) respectively. Considering the inflammatory factors in the pathogenesis of these three nonscarring alopecia forms, we have formulated a mixture for topical usage composed of six different herbal extracts (HE) which have already known antiinflammatory and antioxidant features. Materials and Methods: In addition to performing the phytochemical analysis of HE, we detected the gene expression level of IL-1alpha, the crucial hair loss mediator, for the putative efficacy in nonscarring alopecia. Cell proliferation assay was performed by XTT reagent. After determination of non-cytotoxic concentration, HaCaT cells were treated with HE. RNA isolations were carried out from both non-treated and treated cell groups by using TRI-reagent. Gene expressions of IL-1alpha and as control GAPDH were determined by RT-qPCR analysis. Results: Results were represented as "IL-1alpha/GAPDH Fold Change". HE solution caused statistically significant downregulation of IL-1alpha gene expressions (p<0.0001), compared to untreated control cells. HE treatment ended up with 0.1900 fold change for IL 1alpha. Conclusion: IL-1alpha is a direct growth inhibitory agent in hair follicles and an important actor in the pathogenesis of AGA , TE, and AA. Considering together the vitamins, flavonoids, and trace elements identified in the phytochemical analyses and downregulation of IL-1alpha in HaCaT cells, our HE may be an auxiliary agent in the therapy of these three nonscarring alopecia forms.

We reported the outcome of surgical procedure establishing the approach to multiple osteotomy and fusion to this problem. Retrospectively, 55 feet were reviewed. Step of surgical evaluation were applied to all patients by addressing each component of equinovarus deformity. 31 feet achieved correction by multiple osteotomy. Overall 78% had good outcome and maintained plantigrade foot. This study had outlined a simple surgical step-approached procedure to address fixed equinovarus deformity in cerebral palsy with high success rates. We recommended multiple bone osteotomy to preserve joint motion. PMID- 30302035 TI - Update in Hepatic Encephalopathy.

PMID- 30302038 TI - A Placebo-Controlled, Multicenter, Double-Blind, Phase 2 Randomized Trial of the Pan-Caspase Inhibitor Emricasan in Patients with Acutely Decompensated Cirrhosis. AB - Background: Cirrhosis and acute-on-chronic liver failure (ACLF) are associated with systemic inflammation, and caspase-mediated hepatocyte cell death. Emricasan is a novel, pan-caspase inhibitor. Aims of this study were to assess the pharmacokinetics, pharmacodynamics, safety and clinical outcomes of emricasan in acute decompensation (AD) of cirrhosis. Methods: This was a phase 2, multicentre, double-blind, randomized trial. The primary objective was to evaluate the pharmacokinetics, pharmacodynamics and safety of emricasan in patients with cirrhosis presenting with AD and organ failure. AD was defined as an acute decompensating event <=6 weeks' duration. Patients were randomized proportionately to emricasan 5 mg bid, emricasan 25 mg bid, emricasan 50 mg bid or placebo. Treatment was continued to 28 days, or voluntary discontinuation. Results: Twenty-three subjects were randomized, of whom 21 were dosed (placebo n = 4; 5 mg n = 5; 25 mg n = 7; 50 mg n = 5). Pharmacokinetic data showed 5 mg dose was associated with low plasma levels (<50 ng/ml), and 25 mg and 50 mg doses showed comparable pharmacokinetic profiles. Therefore, for analysis of secondary endpoints, placebo and 5 mg groups were merged into a 'placebo/low-dose' group, and 25 mg and 50 mg groups were merged into a 'high-dose' group. Five deaths occurred amongst the 21 patients, all due to progression of liver disease (2 in placebo/low-dose, 3 in high-dose). No statistically significant changes from baseline MELD score or CLIF-C ACLF score were noted between placebo/low-dose and high-dose groups at day 7 (MELD -1 vs -1, CLIF-C ACLF 0.7 vs 0.8). An initial reduction in cleaved keratin M30 fragment was noted between placebo/low-dose and high-dose groups (percent relative change: day 2: -11.6 vs -42.6, P = 0.017, day 4: -3.5 vs -38.9 P = 0.017) although this did not persist to day 7 (-3.1 vs 20.8, P = 0.342). Conclusion: This study demonstrates that emricasan is safe and well tolerated in advanced liver disease. However, this study fails to provide proof-of-concept support for caspase inhibition as a treatment strategy for ACLF. Trial registration: EudraCT 2012-004245-33. PMID- 30302039 TI - High Prevalence of Cirrhosis at Initial Presentation Among Safety-Net Adults with Chronic Hepatitis B Virus Infection. AB - Background and aims: Delays in diagnosis of chronic hepatitis B virus infection (HBV) may be more common among underserved safety-net populations, contributing to more advanced disease at presentation. We aim to evaluate rates of and predictors of cirrhosis and cirrhosis-related complications among adults with chronic HBV. Methods: We retrospectively evaluated consecutive chronic HBV adults from gastroenterology clinics from July 2014 to May 2016 at a community-based safety-net hospital. Prevalence of cirrhosis or cirrhosis-related complications (ascites, variceal bleeding, hepatic encephalopathy (HE), hepatocellular carcinoma (HCC)) at initial presentation was stratified by sex and race/ethnicity. Predictors of cirrhosis or cirrhosis-related complications at presentation were evaluated with multivariate logistic regression. Results: Among 329 chronic HBV patients (mean age 49.1 years, 55.3% male, 66.5% Asian, 18.6% HBeAg positive) 27.7% had cirrhosis at presentation, 4.3% ascites, 3.7% variceal bleeding, 4.9% HE, and 4.0% HCC. Compared to women, men were more likely to have cirrhosis (34.6% vs. 19.1%, P < 0.01) and variceal bleeding (5.6% vs. 1.4%, P < 0.05) at presentation. On multivariate regression, older age at presentation (OR, 1.04; 95% CI, 1.01-1.07; P = 0.003) and positive HBeAg (OR, 2.57; 95% CI, 1.20 5.51; P = 0.015) were associated with higher odds of cirrhosis at presentation, whereas men had a non-significant trend toward higher odds of cirrhosis (OR, 1.88; 95% CI, 0.99-3.58; P = 0.055). Conclusion: Among adults with chronic HBV at an ethnically diverse safety-net hospital system, nearly 30% of patients had cirrhosis at initial presentation, with the greatest risk seen among patients of male sex, older age, and with positive HBeAg. PMID- 30302040 TI - Impact of Direct Acting Antiviral Drugs in Treatment Naive HCV Cirrhosis on Fibrosis and Severity of Liver Disease: A Real Life Experience from a Tertiary Care Center of North India. AB - Background/aims: Treatment of chronic hepatitis C infection with direct-acting antiviral (DAA) drugs has been highly effective, but data regarding benefit in advanced liver disease is relatively scarce in Indian patients. The aim of this study was to determine the effects of DAA in patients with HCV related cirrhosis (compensated/decompensated) who achieved sustained virological response post therapy at 12 weeks (SVR12). Methods: Sixty-three patients with HCV related cirrhosis treated with sofosbuvir based regimen were evaluated. Data regarding baseline demographics, the severity of liver disease and treatment regimen were collected. The primary end point was to evaluate the effect of treatment (SVR12) on the severity of liver disease with the secondary end point being to observe for any adverse events related to treatment. Results: Treatment naive patients with HCV cirrhosis either due to genotype 1 or genotype 3 were divided into two groups: group A (compensated cirrhosis), group B (decompensated cirrhosis). SVR12 in group A was 91.66% (33/37) and in group, B was 73.17% (30/41). Baseline mean liver stiffness measurement (LSM) in group A was 16.81 +/- 3.57 kPa which decreased to 11.19 +/- 1.75 kPa at SVR12 (P-value <0.0001). Baseline mean APRI and FIB-4 score in group A were 1.228 +/- 0.499 and 2.61 +/- 1.06 and in group B were 2.156 +/- 1.10 and 5.71 +/- 2.06 respectively which decrease to 0.415 +/- 0.115 and 1.25 +/- 0.46 in group A, to 0.759 +/- 0.275 and 2.60 +/- 1.12 in group B following SVR12 (P value <0.0001). Mean MELD-Na improved from baseline 9.93 +/- 2.04, 20.70 +/- 4.52 to 7.21 +/- 0.92, 14.23 +/- 4.51 respectively in group A and B at SVR12 (P-value <0.0001). Child-Turcotte-Pugh score improved by 1 in 27.27% (9/33) and >=2 in 76.67% (23/30) of patients in group A and group B respectively. Conclusion: There was a significant improvement in severity of liver disease as depicted by the decrease in LSM and other noninvasive marker of fibrosis in patients who achieved SVR12 on DAA therapy. PMID- 30302041 TI - Evaluation of Splenic Stiffness in Patients of Extrahepatic Portal Vein Obstruction Using 2D Shear Wave Elastography: Comparison with Intra-Operative Portal Pressure. AB - Background/Aims: To compare splenic stiffness (SS) with intra-operative portal pressures (PPs) in patients of extrahepatic portal vein obstruction (EHPVO). Methods: Twenty-one patients (14 males; 7 females) of mean age 20.4 years with clinical and sonographic diagnosis of EHPVO were included in this approved prospective study. Endoscopy for esophageal varices (EV) was done in all patients followed by ultrasonographic 2D shear wave elastography (SWE) of spleen. Three values were taken at different areas of spleen avoiding major vessels and mean was calculated. Intra-operative PP was measured from an omental vein during proximal spleno-renal shunt surgery. The PP was compared and correlated with SS along with other parameters. Results: The mean SS was 46.04 +/- 8.0 kPa and the mean PP was 33.29 +/- 4.1 mmHg. There was no significant correlation between PP and SS (P = 0.61) and between grades of EV and SS (P = 0.38). Significant correlation was seen between grades of EV and PP (0.04). SS also did not show significant correlation with splenic size or duration of disease. Conclusion: SS measured by 2D SWE did not correlate with PP and thus may not help in predicting gastrointestinal bleed in patients of EHPVO. PMID- 30302042 TI - Race and Gradient Difference Are Associated with Increased Risk of Hepatic Encephalopathy Hospital Admission After Transjugular Intrahepatic Portosystemic Shunt Placement. AB - Background/Aims: Hepatic encephalopathy (HE) is a well-recognized complication of transjugular intrahepatic portosystemic shunt (TIPS) placement. The aim of this investigation was to evaluate incidence and predictors of post-TIPS HE necessitating hospital admission in a non-clinical trial setting. Methods: We performed a retrospective cohort study identifying 273 consecutive patients undergoing TIPS from 2010 to 2015 for any indication; 210 met inclusion/exclusion criteria. The primary endpoint was incidence of post-TIPS HE defined as encephalopathy with no other identifiable cause requiring hospitalization within 90 days of TIPS. Clinical demographics and procedural variables were collected and analyzed to determine predictors of readmission for post-TIPS HE. Categorical variables were analyzed using Fisher's exact test; continuous variables were compared using Levene's t-test and student's t-test; P < 0.05, significant. Results: Forty-two of 210 patients (20%) developed post-TIPS HE requiring hospitalization within 90 days. On analysis of cohorts (post-TIPS HE vs. no post TIPS HE): non-white race (31.0% vs. 17.5%, P = 0.022) and increased hepatic venous pressure gradient (HVPG) difference during TIPS (10.5 vs. 8.9 mmHg, P = 0.030) were associated with an increased incidence of HE requiring readmission within 90 days. Conclusions: HE remains a common complication of TIPS. Non Caucasian race is a significant clinical demographic associated with increased risk for readmission. Independent of initial or final HVPG, HVPG difference appears to be a significant modifiable technical risk factor. In the absence of clear preventative strategies for post-TIPS encephalopathy, non-Caucasians with HVPG reductions >9 mmHg may require targeted follow up evaluation to prevent hospital readmission. PMID- 30302043 TI - Pathogenesis of Hepatic Encephalopathy in Chronic Liver Disease. AB - Hepatic encephalopathy (HE) is a complex neuropsychiatric syndrome that occurs during chronic liver disease (CLD). While ammonia and other precipitating factors in liver disease including inflammation, bile acids, oxidative stress, and lactate play a role in the pathogenesis of HE, the exact mechanism that leads to HE is not fully understood. Notably, accumulating evidence points toward a synergic effect rather than independent actions among precipitating factors that contributes to the development and severity of HE in CLD. Hence, this review is aimed to briefly discuss the single and synergic interplay of pathological factors in the progression and severity of HE. PMID- 30302045 TI - Role of Peripheral Inflammation in Hepatic Encephalopathy. AB - A growing body of evidence now highlights a key role for systemic inflammation in altering behavior and mood in patients with liver disease. How inflammation occurring in the periphery in the context of liver disease, communicates with the brain to mediate changes in neurotransmission and thereby behavior is incompletely understood. Traditional routes of communication between the periphery and the brain involve neural (i.e. vagal afferent nerves) and humoral (blood-borne) pathways, with increased circulating levels of endotoxin and cytokines (especially Tumor Necrosis Factor alpha, TNFalpha) that occur during systemic inflammatory responses, as being primarily implicated in mediating signaling via these pathways. However, in recent years communication via peripheral immune-cell-to-brain and the gut-microbiota-to-brain routes have received increasing attention in the context of liver disease for their ability to modulate brain function, and generate a spectrum of symptoms ranging from fatigue and altered mood to overt Hepatic Encephalopathy (HE). In this review, we discuss periphery-to-brain communication pathways and their potential role in mediating systemic inflammation-associated alterations in behavior, that are in turn ultimately part of a spectrum of brain changes linked to the development of clinically apparent HE. PMID- 30302044 TI - Hyperammonemia in Hepatic Encephalopathy. AB - The precise mechanism underlying the neurotoxicity of Hepatic Encephalopathy (HE) is remains unclear. The dominant view has been that gut-derived nitrogenous toxins are not extracted by the diseased liver and thereby enter the brain. Among the various toxins proposed, the case for ammonia is most compelling. Events that lead to increased levels of blood or brain ammonia have been shown to worsen HE, whereas reducing blood ammonia levels alleviates HE. Clinical, pathological, and biochemical changes observed in HE can be reproduced by increasing blood or brain ammonia levels in experimental animals, while exposure of cultured astrocytes to ammonium salts reproduces the morphological and biochemical findings observed in HE. However, factors other than ammonia have recently been proposed to be involved in the development of HE, including cytokines and other blood and brain immune factors. Moreover, recent studies have questioned the critical role of ammonia in the pathogenesis of HE since blood ammonia levels do not always correlate with the level/severity of encephalopathy. This review summarizes the vital role of ammonia in the pathogenesis of HE in humans, as well as in experimental models of acute and chronic liver failure. It further emphasizes recent advances in the molecular mechanisms involved in the progression of neurological complications that occur in acute and chronic liver failure. PMID- 30302046 TI - Cerebral Blood Flow and Metabolism in Hepatic Encephalopathy-A Meta-Analysis. AB - Hepatic Encephalopathy (HE) is associated with abnormalities in brain metabolism of glucose, oxygen and amino acids. In patients with acute liver failure, cortical lactate to pyruvate ratio is increased, which is indicative of a compromised cerebral oxidative metabolism. In this meta-analysis we have reviewed the published data on cerebral blood flow and metabolic rates from clinical studies of patients with HE. We found that hepatic encephalopathy was associated with reduced cerebral metabolic rate of oxygen, glucose, and blood flow. One exemption was in HE type B (shunt/by-pass) were a tendency towards increased cerebral blood flow was seen. We speculate that HE is associated with a disturbed metabolism-cytopathic hypoxia-and that type specific differences of brain metabolism is due to differences in pathogenesis of HE.

AB - Background/objectives: l-Ornithine l-Aspartate (LOLA) is a mixture of two endogenous amino acids with the capacity to fix ammonia in the form of urea and/or glutamine. Its' efficacy for the treatment of Hepatic Encephalopathy (HE), a known hyperammonemic disorder, remains the subject of debate. This study quantitatively analyzed the efficacy of LOLA in patients with cirrhosis and HE. Methods: Efficacy was defined as the extent of lowering of blood ammonia and improvement of mental state assessed in clinically overt HE (OHE) by Westhaven criteria or psychometric testing for assessment of Minimal HE (MHE). Appropriate keywords were used for electronic and/or manual searches of databases to identify RCTs for inclusion. Study quality and risk of bias were assessed using the Jadad Composite Scale together with The Cochrane Scoring Tool. Random Effects Models were used to express pooled Risk Ratio (RR) or Mean Difference (MD) with associated 95% Confidence Intervals (CI). Results: 10 RCTs (884 patients) were included. Regression analysis showed no evidence of publication bias or other small study effects. Eight RCTs had low risk of bias by Jadad/Cochrane criteria. Comparison with placebo/no intervention controls revealed that LOLA was significantly more effective for improvement of mental state in all types of HE (RR 1.36 (95% CI 1.10-1.69), p = 0.005), OHE (RR: 1.19, 95% CI of 1.01-1.39, test for overall effect: Z = 2.14, p = 0.03), MHE (RR: 2.15 (1.48-3.14), p < 0.0001) and for lowering of blood ammonia (MD: -17.50 MUmol/l (-27.73 to (-7.26)), p = 0.0008). Improvement of mental state was greater in trials with low risk of bias. Heterogeneity was reduced in trials from Europe or with >100 participants. Oral LOLA appeared particularly effective for the treatment of MHE. Conclusion: LOLA appears to improve mental state and lower ammonia in patients with HE or MHE. Further studies are required in some subgroups of HE and in the era of HE reclassification. PMID- 30302047 TI - Hepatic Encephalopathy and Astrocyte Senescence. AB - Hepatic Encephalopathy (HE) is a severe complication of acute or chronic liver diseases with a broad spectrum of neurological symptoms including motor disturbances and cognitive impairment of different severity. Contrary to former beliefs, a growing number of studies suggest that cognitive impairment may not fully reverse after an acute episode of overt HE in patients with liver cirrhosis. The reasons for persistent cognitive impairment in HE are currently unknown but recent observations raise the possibility that astrocyte senescence may play a role here. Astrocyte senescence is closely related to oxidative stress and correlate with irreversible cognitive decline in aging and neurodegenerative diseases. In line with this, surrogate marker for oxidative stress and senescence were upregulated in ammonia-exposed cultured astrocytes and in post mortem brain tissue from patients with liver cirrhosis with but not without HE. Ammonia induced senescence in astrocytes involves glutamine synthesis-dependent formation of reactive oxygen species (ROS), p53 activation and upregulation of cell cycle inhibitory factors p21 and GADD45alpha. More recent studies also suggest a role of ROS-induced downregulation of Heme Oxygenase (HO)1-targeting micro RNAs and upregulation of HO1 for ammonia-induced proliferation inhibition in cultured astrocytes. Further studies are required to identify the precise sequence of events that lead to astrocyte senescence and to elucidate functional implications of senescence for cognitive performance in patients with liver cirrhosis and HE.

AB - While Autoimmune Hepatitis (AIH) may recur in patients after liver transplant, an AIH like presentation (positive auto antibodies, raised immunoglobulin G, raised transaminases and histology showing plasma cell rich infiltrate) may also occur in liver transplant recipients who had transplant for some other disease, called De novo Autoimmune Hepatitis (DAIH). A timely diagnosis and treatment can prevent further graft dysfunction. We report 4 cases of DAIH after living donor liver transplantation. PMID- 30302050 TI - Percutaneous Transhepatic Approach for Recanalization of Superior Mesenteric and Portal Vein in a Patient With Pancreatic Neuroendocrine Tumor Presenting With Bleeding Duodenal Varices: A Brief Case Report. AB - Occlusion of Portal Vein (PV) and Superior Mesenteric Vein (SMV) is a known effect of local infiltration by pancreatic or mesenteric neuroendocrine tumors. Venous occlusion leads to formation of collateral pathways to restore hepatopetal flow in main PV and these collateral pathways can be seen in the form of ectopic (duodenal or jejunal) varices. We present a case of bleeding duodenal varices secondary to SMV occlusion by a locally infiltrating pancreatic neuroendocrine tumor which was successfully treated by coil embolization of varices and SMV stenting of the occluded venous segment after failure of endoscopic glue injection. Various endovascular minimally invasive approaches have been described in literature for recanalization of SMV in such clinical scenarios which maybe challenging to treat for surgical methods. We recommend use of the retrograde transhepatic technique for recanalization of occluded SMV and embolization of associated varices as an alternate treatment option in such scenarios. PMID- 30302051 TI - Primary Hepatic Leiomyosarcoma: Histopathologist's Perspective of a Rare Case. AB - Primary hepatic leiomyosarcoma is a rare primary mesenchymal tumor of the liver requiring exclusion of any other primary site of origin and histological and immunohistochemical exclusion of other hepatic/extrahepatic tumors with spindle cell morphology. Only about 70 cases are reported in the English literature and many of these tumors have predisposing conditions in the form of immunosuppression or associated malignancies. The occurrence of this tumor in the immunocompetent individual is also known. Histomorphology of this tumor shows a spindle cell lesion which needs to be distinguished from other spindle cell lesions of this region. The main diagnostic challenge of this tumor lies in its rarity, lack of awareness and morphological mimickers in the given site. A complete range of immunohistochemical markers is required to distinguish the lesion from its close morphological mimickers. Here, we discuss a case of primary hepatic leiomyosarcoma in an adult female patient with detailed histomorphological differentials and respective immunoprofiles.

AB - A 10-year-old female child, a known case of Beta-Thalassemia major with superimposed chronic Hepatitis C Viral (HCV) infection, underwent bone marrow transplantation and presented, 7 months later, with worsening hepatic functions and skin rash. Considering the wide variety of possible etiologies, she was evaluated and later confirmed as a case of hepatic dysfunction secondary to HCV related hepatic injury with concomitant chronic graft versus host disease (dermatological involvement only). PMID- 30302053 TI - Monte Carlo Simulations Demonstrate Algorithmic Interventions Over Time Reduce Hospitalisation in Patients With Schizophrenia and Bipolar Disorder. AB - Non-adherence with pharmacologic treatment is associated with increased rates of relapse and rehospitalisation among patients with schizophrenia and bipolar disorder. To improve treatment response, remission, and recovery, research efforts are still needed to elucidate how to effectively map patient's response to medication treatment including both therapeutic and adverse effects, compliance, and satisfaction in the prodromal phase of illness (ie, the time period in between direct clinical consultation and relapse). The Actionable Intime Insights (AI2) application draws information from Australian Medicare administrative claims records in real time when compliance with treatment does not meet best practice guidelines for managing chronic severe mental illness. Subsequently, the AI2 application alerts clinicians and patients when patients do not adhere to guidelines for treatment. The aim of this study was to evaluate the impact of the AI2 application on the risk of hospitalisation among simulated patients with schizophrenia and bipolar disorder. Monte Carlo simulation methodology was used to estimate the impact of the AI2 intervention on the probability of hospitalisation over a 2-year period. Results indicated that when the AI2 algorithmic intervention had an efficacy level of (>0.6), over 80% of actioned alerts were contributing to reduced hospitalisation risk among the simulated patients. Such findings indicate the potential utility of the AI2 application should replication studies validate its methodologic and ecological rigour in real-world settings. PMID- 30302054 TI - Ammonia-Oxidizing Archaea (AOA) Play with Ammonia-Oxidizing Bacteria (AOB) in Nitrogen Removal from Wastewater. AB - An increase in the number of publications in recent years indicates that besides ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA) may play an important role in nitrogen removal from wastewater, gaining wide attention in the wastewater engineering field. This paper reviews the current knowledge on AOA and AOB involved in wastewater treatment systems and summarises the environmental factors affecting AOA and AOB. Current findings reveal that AOA have stronger environmental adaptability compared with AOB under extreme environmental conditions (such as low temperature and low oxygen level). However, there is still little information on the cooperation and competition relationship between AOA and AOB, and other microbes related to nitrogen removal, which needs further exploration. Furthermore, future studies are proposed to develop novel nitrogen removal processes dominated by AOA by parameter optimization. PMID- 30302055 TI - Primary cutaneous nocardiosis: a diagnosis of consideration in a renal transplant recipient. AB - Background: The cutaneous nocardiosis remains a diagnostic challenge: similar clinical presentations as of cutaneous diseases with different etiology-and the inherent difficulty in cultivating the pathogen. Case presentation: Herein, we describe a case of primary cutaneous nocardiosis in a renal transplant recipient; treated with anti-tubercular drugs due to misdiagnosis of cutaneous tuberculosis. On clinical examinations, a few red erythematous papules with erosions and crusting seen, over prior surgery scar of renal transplant. Multiple basophilic colonies surrounded by neutrophilic abscesses and granulation tissue were seen on histopathological examinations. The presumptive identification was done by Ziehl neelson staining, bacterial culture, biochemical interpretations, and susceptibility pattern of the isolates to antibiotics. Radiographic imaging of brain and lungs were normal; no feature of disseminated nocardiosis seen. After 3 months of an anti-microbial therapy i.e. TMP-SMX(sulfamethoxazole and trimethoprim); the patient underwent progressive changes no relapse noted; transplant function observed in a good state, found asymptomatic with limited side effects on a regular follow up till now. Conclusion: Cutaneous nocardiosis can occur in the renal-transplant patient. Therefore, a high degree of clinical suspicions, extensive clinical differentiation, early detection of the pathogen, apt selection of the antimicrobial therapy, correct dosing, and treatment duration is crucial for successful outcomes. PMID- 30302056 TI - Quality of nursing work life and turnover intention among nurses of tertiary care hospitals in Riyadh: a cross-sectional survey. AB - Background: Nurse turnover has a negative impact on the ability to meet patient needs and provide a high quality of care, which may create more stress on other staff due to increased workloads. This can lead to critical changes in the behavior of nurses towards their jobs resulting in low work satisfaction, low productivity, and leaving the organization. Thus, this study aimed to assess the quality of nursing work life (QNWL), to explore the nurses' turnover intention and to examine the correlation between QNWL and nurses' turnover intention. Methods: A cross-sectional survey was conducted on nurses with at least 1 year of nursing experience at two hospitals selected randomly from Riyadh, Saudi Arabia: King Fahad Medical City and King Faisal Specialized Hospitals. Data were collected using a self-administered questionnaire comprising four sections (Brooks' survey of QNWL, Anticipated Turnover Scale (ATS), open-ended questions and demographic characteristics). Results: A sample of 364 nurses was recruited. Results proposed that the participants were dissatisfied with their work life (54.7%), with almost 94% indicating a turnover intention from their current hospital. Moreover, 154 (93.3%) out of 165 nurses who reported satisfaction with QNWL indicated the intention to turnover. The correlation between QNWL and ATS for binary variables was too week (r = - 0.024) and statistically not significant (p = 0.206). Conclusion: The QNWL and nurse turnover are challenging issues for healthcare organizations because of its consequences and impact on patient care. Our study provided critical findings low indication satisfaction of nurses with their QNWL and a high turnover intention. The results of this study could be used as a nexus for the development of regulations and practical strategies to enhance QNWL and to decrease the turnover. PMID- 30302057 TI - Conserved cell populations in doxorubicin-resistant human nasal natural killer/T cell lymphoma cell line: super multidrug resistant cells? AB - Background: Extranodal NK/T-cell lymphoma, nasal type (ENKL) is a distinct clinicopathological entity and EBV-associated disease that is highly aggressive. Many patients had failed to respond to conventional chemotherapy or relapsed after treatment. Multi-drug resistance is a major cause that leads to these desperate failures. However, the specific mechanism of drug resistance is still unclear. Methods: In the previous study, we firstly developed a doxorubicin resistant ENKL cell line known as SNK-6/ADM, and then a small quantity of side population (SP) cells were derived from SNK-6/ADM and named SNK-6/ADM-SP. In order to explore the biological characteristics and mechanism of drug-resistance of these cells, SNK-6, SNK-6/ADM and SNK-6/ADM-SP cells were utilized to evaluate potentially differences of chemotherapy resistance index (RI), morphology, proliferation, cell cycles, expression of ATP-binding cassette (ABC) transporters (ABCG1, ABCG2 and ABCC4) and surface markers, cytokine sensitivity, and situation of EBV infection. Results: We identified SNK-6/ADM-SP is a specific multidrug resistant cell population with a higher level of RI than SNK-6/ADM. Relevant evaluations showed that SNK-6/ADM-SP presented a series of conserved biological behaviors including relatively poor proliferation ability, high expression of ABCG2, weak sensitivity to IL-15 which could stimulate normal ENKL cells' proliferation and differentiation, and EBV inhibition with low level of EBV-DNA replication and EBV-antigen expression. Conclusions: This discovered cellular heterogeneity of ENKL could provide a new perspective to better understand the mechanisms of drug resistance and overcome elusive response to chemotherapy of ENKL.

PMID- 30302058 TI - Overexpression of LASS2 inhibits proliferation and causes G0/G1 cell cycle arrest in papillary thyroid cancer. AB - Background: The aim of this study was to investigate the role of LAG1 longevity assurance homologue 2 (LASS2) in papillary thyroid cancer (PTC). Methods: Immunohistochemistry staining was conducted to explore the expression levels of LASS2 in PTC tissues and adjacent normal thyroid tissues and nodular goiter tissues. Western blotting and RT-qPCR were performed to explore the expression levels of LASS2 in three PTC cell lines (TPC-1, K1, BCPAP). An Adv-LASS2-GFP recombinant adenovirus vector was constructed and transduced into BCPAP cells. Then CCK-8 assay, colony formation assay, cell cycle distribution, and apoptosis were performed. Western blotting was used to examine the expression of p21, cyclin D1, cyclin-dependent kinase 4, p53 and p-p53. Results: LASS2 was downregulated in PTC tissues compared with adjacent thyroid tissues or nodular goiter tissues. In addition, the expression of LASS2 was found to be associated with TNM stage and lymph node metastasis. BCPAP cells expressed the lowest LASS2 compared to TPC-1 cells or K1 cells. Overexpression of LASS2 significantly inhibited proliferation, promoted apoptosis and caused G0/G1 cell cycle arrest in BCPAP cells. Furthermore, overexpression of LASS2 significantly increased the expression of p21, inhibited the expression of cyclin D1 and cyclin-dependent kinase 4, and increased the expression of p-p53, but did not effect the expression of p53 in BCPAP cells. Conclusion: Our findings indicate that overexpression of LASS2 inhibits PTC cell proliferation, promotes apoptosis and causes G0/G1 cell cycle arrest via a p53-dependent pathway. Thus, LASS2 may serve as a novel biomarker in PTC. PMID- 30302060 TI - Economic Comparison of Serologic and Molecular Screening Strategies for Hepatitis C Virus. AB - Background: Hepatitis C virus (HCV) screening is traditionally performed using an enzyme-linked immunosorbent assay (ELISA), and HCV infection is confirmed by measuring the viral load using polymerase chain reaction (PCR). An alternative screening approach is to use only PCR, without the ELISA pretest. Methods: We compared the cost ratio of screening for HCV using 2 approaches: (1) ELISA followed by PCR testing, and (2) PCR testing alone. The results were analyzed using a decision analysis model. A sensitivity analysis and a threshold analysis were performed by varying both the prevalence of HCV infection (to encompass populations in which viral infection is overrepresented) as well as the costs of PCR testing. Results: Under baseline assumptions, the costs of PCR testing alone were substantially greater than the combination of ELISA and PCR testing. The cost per patient screened using combination testing was $42.30, whereas testing with only PCR cost $200.00 per patient. The prevalence of HCV had a greater impact on the cost ratio than did the costs of laboratory tests. The use of PCR testing alone became less costly only when the prevalence of HCV infection was greater than 69.5%. Otherwise, the costs of the 2 approaches were similar when the cost of PCR was 1% of that of ELISA. Conclusion: From a pharmacoeconomic basis, the current approach of HCV screening (ie, using ELISA and PCR testing) was found to be the less expensive screening strategy in a general US population and for most cohorts in which HCV infection was noted to be overrepresented. Screening for HCV is less costly using solely PCR testing only when the prevalence of HCV infection is greater than 69.5%. PMID- 30302061 TI - The Role of Allergy Testing in Eosinophilic Esophagitis. AB - Eosinophilic esophagitis (EoE) is defined as a chronic, immune/antigen-mediated esophageal disease that can lead to symptoms of esophageal dysfunction. This disease is seen in both children and adults. Approximately 70% of patients with EoE have food antigen sensitization or other atopic conditions, suggesting an allergic etiology in the pathogenesis of the disease. The role of allergy testing to identify foods that lead to EoE is unclear. Three types of allergy tests currently exist: skin prick testing, atopy patch testing, and immunoassays for serum food-specific immunoglobulin E. It is important for gastroenterologists to work in conjunction with allergist colleagues in the care of patients with EoE, particularly in the management of comorbid atopic conditions. PMID- 30302063 TI - Highlights From the New ACG Guideline on Crohn's Disease Management. PMID- 30302062 TI - Perianal Fistulas in Patients With Crohn's Disease, Part 1: Current Medical Management. AB - Despite significant advances in the treatment of luminal inflammatory bowel disease, the treatment of perianal fistulas remains a clinical challenge. Perianal fistulas are traditionally described using the Parks classification based on their relationship to the external and internal anal sphincters. Traditional therapy for perianal fistulas focuses on antibiotics such as metronidazole or ciprofloxacin. However, medical management has expanded over the years to include immunomodulators and, most recently, biologic agents. Newer techniques such as intrafistulous biologic injections are also being explored as potentially effective treatments for patients with fistulizing disease. Here, in the first of a 2-part series on perianal fistulas in patients with Crohn's disease, we discuss the anatomy and classification of perianal fistulas as well as current medical therapies, including antibiotics, immunomodulators, biologic agents, and novel therapeutic agents. The second part of the series will focus on the surgical modalities that are available for patients with perianal fistulas in addition to novel endoscopic techniques and future therapies that are being investigated for the treatment of fistulizing Crohn's disease.

AB - To establish a complete technical solution for the automatic radiation biological dose estimation platform for biological dose estimation and classification of the wounded in large-scale radiation accidents, the "dose-effect curve by dicentric chromosome (DIC) automatic analysis" was established and its accuracy was verified. The effects of analyzed cell number and the special treatment of the culture on dose estimation by DIC automatic analysis were studied. Besides, sample processing capabilities of the special equipments were tested. The fitted "dose-effect curve by DIC automatic analysis" was presented as follows: Y = (0.01806 +/- 0.00032) D 2 + (0.01279 +/- 0.00084) D + (0.0004891 +/- 0.0001358) (R 2 = 0.961). Three-gradient scanning method, culture refrigeration method, and interprofessional collaboration under extreme conditions were proposed to improve the detection speed, prolong the sample processing time window, and reduce the equipment investment. In addition, the optimized device allocation ratio for the automatic biological dose estimation laboratory was proposed to eliminate the efficiency bottleneck. The complete set of technical solutions for the high throughput automatic biological dose estimation laboratory proposed in this study can meet the requirements of early classification and rapid biological dose assessment of the wounded during the large-scale nuclear radiation events, and it is worthy of further promotion.

AB - Objective: We are trying to investigate the possibility, safety, and benefits of replacing the role of T-tube by another more safe and effective procedure for biliary decompression in the case of common bile duct (CBD) exploration. Methods: Our present study includes fifty consecutive patients who underwent a traditional CBD exploration due to choledocholithiasis. Patients were divided into 2 equal groups. In the 1st group, a spontaneously expelled Nelaton tube is placed in the CBD to aid in bile drainage to the duodenum, while in the 2nd group, a conventional T-tube is placed to decompress the CBD in the early postoperative (PO) days to a drainage bag. Operative and PO data as well as PO hospital stay time were recorded. All data were collected and statistically analyzed. Results: The mean operative time and PO hospital stay days were significantly low (p value < 0.05) in the Nelaton tube drainage group compared with the T-tube drainage group. On the other hand, the mean time needed for the abdominal drain removal was significantly higher in the T-tube drainage group (p value < 0.05). Conclusion: Nelaton tube with internal biliary drainage is effective and safer than T-tube drainage and it helps in reduction of the PO hospital stay time. In addition, it avoids all short-term complications of T-tube. PMID- 30302072 TI - Pathophysiology and Classification of Cardiovascular Diseases Caused by Atherosclerosis.

AB - Grain amaranth-wheat flour bread was optimised using ascorbic acid (0.03% dry weight basis) and fungal alpha-amylase (10 ppm) to investigate their effects on sensory properties of the breads. Six formulations were used in the ratios of 5:95, 10:90, 15:85, 20:80 and 25:75 grain amaranth to wheat flour compositions, while the control bread had 100% wheat flour. Consumer acceptability and preference ranking tests were conducted to describe and evaluate preference and acceptability of the breads. Analysis of consumer acceptability data revealed that there were significant differences (p < 0.05) for all the samples in all the attributes tested. Overall consumer acceptability results showed no difference at 25% for all improvers. Principal component analysis for descriptive tests performed by a trained panel demonstrated variations among the breads in graininess, elasticity, crumb colour, stickiness and crumb moistness regardless of the improvers used. The study concludes that using improvers to optimise grain amaranth-wheat flour bread can help improve both the nutritional and organoleptic properties of bread. PMID- 30302087 TI - Rice bran triterpenoids improve postprandial hyperglycemia in healthy male adults: a randomized, double-blind, placebo-controlled study. AB - Background: Compared to white rice, brown rice induces a lower glycemic response in healthy and diabetic humans. This effect is partly attributed to the higher amounts of water- or oil-soluble bran components and dietary fiber in brown rice. We hypothesized that dietary supplementation with oil-soluble rice bran triterpenoids (RBTs; triterpene alcohol and sterol prepared from rice bran) might reduce the incidence of postprandial hyperglycemia in healthy humans. Objective: We examined the acute effects of a single RBT-supplemented meal on the postprandial blood glucose responses of healthy male adults in a double-blind, randomized, placebo-controlled, crossover trial. Design: Nineteen subjects consumed a test meal containing either placebo- or RBT-supplemented olive oil. Blood biomarkers were evaluated in a fasting state and up to 240 min postprandially. Results: Compared to the placebo-supplemented meal, the RBT supplemented meal significantly suppressed the increase in postprandial blood glucose level. A subclass analysis revealed that RBT-supplemented oil significantly reduced blood glucose increases in subjects with higher postprandial blood glucose elevations. Postprandial increases in blood insulin, glucose-dependent insulinotropic peptide (GIP), and glucagon-like peptide-1 (GLP 1) levels did not differ between the groups. Conclusion: These results suggest that RBT consumption improves postprandial hyperglycemia in healthy humans, especially those with higher postprandial glucose increases. PMID- 30302088 TI - Prediction of the Risk of Laparoscopy-Assisted Gastrectomy by Comparing Visceral Fat Area and Body Mass Index. AB - Propose: The purpose of this study was to compare the accuracy of visceral fat area (VFA) and body mass index (BMI) in predicting the risk of laparoscopic assisted gastrectomy. Methods: Clinicopathological and imaging data of 133 patients who underwent laparoscopy-assisted gastrectomy were recorded, including 17 cases of conversion to open surgery. The remaining 116 patients were retrospectively analyzed after we excluded 17 patients who had been transferred to laparotomy. The patients were divided into two groups according to BMI (<=25 kg/m2: BMI-L group; >25 kg/m2: BMI-H group) and VFA (<=100 cm2: VFA-L group; >100 cm2: VFA-H group). Clinical outcomes were compared between the BMI and VFA subgroups. Results: There were no differences in intraoperative blood loss and the number of harvested lymph nodes between low and high patients defined by BMI and VFA (p > 0.050). However, in the comparison of patients who underwent laparoscopic resection only, it was found that the operation time and intraoperative blood loss of the VFA-H group were more than those of the VFA-L group (p < 0.050). Compared to the VFA-L group, the VFA-H group had later first exhaust time (p = 0.018), more complications (p < 0.001), and longer hospital stays (p = 0.049). However, no similar conclusion was obtained in the BMI group (p > 0.050). Conclusion: This study demonstrates that VFA better evaluates the difficulty of laparoscopy-assisted gastrectomy and the risk of postoperative complications than BMI. PMID- 30302089 TI - Staffing at Ambulatory Endoscopy Centers in the United States: Practice, Trends, and Rationale. AB - Background: Endoscopy nurse (RN) has a pivotal role in administration and monitoring of moderate sedation during endoscopic procedures. When sedation for the procedure is administered and monitored by an anesthesia specialist, the role of an RN is less clear. The guidelines on this issue by nursing and gastroenterology societies are contradictory. Methods: Survey study of endoscopy lab managers and directors at outpatient endoscopy units in Texas. The questions related to staffing patterns for outpatient endoscopies and responsibilities of different personnel assisting with endoscopies. Results: Responses were received from 65 endoscopy units (response rate 38%). 63/65 (97%) performed at least a few cases with an anesthesia specialist. Of these, 49/63 (78%) involved only an endoscopy technician, without an additional RN in the room. At 12/49 (25%) units, the RN performed tasks of an endoscopy technician. At 14/63 (22%), an additional RN was present during endoscopic procedures and performed tasks not directly related to patient care. Conclusions: Many ambulatory endoscopy units do not have an RN present at all times when sedation is administered by an anesthesia specialist. An RN, when present, did not perform tasks commensurate with the education and training. This has implications about optimal utilization of nurses and cost of performing endoscopies. PMID- 30302091 TI - Development and Validation of an HPLC-MS/MS Method for Rapid Simultaneous Determination of Cefprozil Diastereomers in Human Plasma. AB - Background: Both cis- and trans-cefprozil have antimicrobial activity, but their potencies are quite different. It is therefore necessary to develop a sensitive method to simultaneously determine both isomers for pharmacokinetic and bioequivalence studies. Methods: An LC-MS/MS method, using stable isotope-labeled cefprozil as the internal standard, was developed and validated. The analytes were extracted from plasma by protein precipitation and separated on a reverse phase C18 column using a gradient program consisting of 0.5% formic acid and acetonitrile within 4 min. The mass spectrometry acquisition was performed with multiple reaction monitoring in positive ion mode using the respective [M+H]+ ions, m/z 391.2->114.0 for cefprozil and 395.0->114.5 for cefprozil-D4. Results: The calibration curves were linear over the ranges of 0.025-15 MUg/mL for cis cefprozil and 0.014-1.67 MUg/mL for trans-cefprozil. The accuracies for the cis and trans isomers of cefprozil were 93.1% and 103.0%, respectively. The intra- and interassay precisions for the QC samples of the isomers were < 14.3%. The intra- and interassay precisions at the LLOQ were < 16.5%. Conclusions: The method was sensitive and reproducible and was applied in a pilot pharmacokinetic study of healthy volunteers. PMID- 30302090 TI - Serum Matrix Metalloproteinase 9 and Macrophage Migration Inhibitory Factor (MIF) Are Increased in Young Healthy Nonobese Subjects with Positive Family History of Type 2 Diabetes. AB - Insulin resistance increases the risk for cardiovascular disease (CVD) even in the absence of classic risk factors, such as hyperglycemia, hypertension, dyslipidemia, and obesity. Low-grade chronic inflammatory state is associated both with insulin resistance and atherosclerosis. An increased circulating level of proinflammatory proatherogenic factors and biomarkers of endothelial activation was observed in diabetes and CVD. The aim of our study was to assess serum proatherogenic and proinflammatory factors in young healthy nonobese subjects with positive family history of type 2 diabetes. We studied 74 young healthy nonobese subjects with normal glucose tolerance (age < 35 years, BMI < 30 kg/m2), 29 with positive family history of type 2 diabetes (relatives, 25 males and 4 females) and 45 subjects without family history of diabetes (control group, 39 males and 6 females). Hyperinsulinemic-euglycemic clamp was performed, and serum concentrations of monocyte chemoattractant protein-1 (MCP-1), interleukin 18 (IL-18), macrophage inhibitory cytokine 1 (MIC-1), macrophage migration inhibitory factor (MIF), matrix metalloproteinase (MMP-9), and soluble forms of adhesion molecules were measured. Relatives had markedly lower insulin sensitivity (p = 0.019) and higher serum MMP-9 (p < 0.001) and MIF (p = 0.006), but not other chemokines and biomarkers of endothelial function. Insulin sensitivity correlated negatively with serum MMP-9 (r = -0.23, p = 0.045). Our data show that young healthy subjects with positive family history of type 2 diabetes already demonstrate an increase in some nonclassical cardiovascular risk factors.

In 2010, PLA became the second highest consumed bioplastic in the world due to its wide application. Conventionally, PLA is produced by direct condensation of lactic acid monomer and ring opening polymerization of lactide, resulting in lower molecular weight and lesser strength of polymer. Furthermore, conventional methods of PLA production require a catalyst which makes it inappropriate for biomedical applications. Newer method utilizes metabolic engineering of microorganism for direct production of PLA through fermentation which produces good quality and high molecular weight and yield as compared to conventional methods. PLA is used as decomposing packaging material, sheet casting, medical implants in the form of screw, plate, and rod pin, etc. The main focus of the review is to highlight the synthesis of PLA by various polymerization methods that mainly include metabolic engineering fermentation as well as salient biomedical applications of PLA.

AB - Hepatitis A is a common viral infection with a benign course but in rare cases can progress to acute liver failure. It usually presents with abdominal pain, nausea, vomiting, diarrhea, jaundice, anorexia, or asymptomatically, but it can also present atypically with relapsing hepatitis and prolonged cholestasis. In addition, extrahepatic manifestations have been reported, including urticarial and maculopapular rash, acute kidney injury, autoimmune hemolytic anemia, aplastic anemia, acute pancreatitis, mononeuritis, reactive arthritis, glomerulonephritis, cryoglobulinemia, Guillain-Barre syndrome, and pleural or pericardial effusion. A rare manifestation of hepatitis A is acute myocarditis. We report a case of a young woman who presented with "flu-like symptoms" and was found to have severe elevation of liver enzymes due to acute hepatitis A infection. On her 3rd day of admission, the patient developed chest pain and nonspecific electrocardiographic changes. Her troponins rose to 16.4 ng/mL, and a transthoracic echocardiogram revealed global hypokinesis and a depressed ejection fraction at 30%. A CT angiography showed no evidence of significant coronary artery disease. The patient was managed supportively, and symptoms and laboratory findings slowly improved over the next 7 days. Her chest pain resolved and a follow-up echocardiogram showed improved ejection fraction to 45%. PMID- 30302095 TI - When the situation almost cannot be worse.... PMID- 30302094 TI - Molecular Mechanisms of Transdifferentiation of Adipose-Derived Stem Cells into Neural Cells: Current Status and Perspectives. AB - Neurological diseases can severely compromise both physical and psychological health. Recently, adult mesenchymal stem cell- (MSC-) based cell transplantation has become a potential therapeutic strategy. However, most studies related to the transdifferentiation of MSCs into neural cells have had disappointing outcomes. Better understanding of the mechanisms underlying MSC transdifferentiation is necessary to make adult stem cells more applicable to treating neurological diseases. Several studies have focused on adipose-derived stromal/stem cell (ADSC) transdifferentiation. The purpose of this review is to outline the molecular characterization of ADSCs, to describe the methods for inducing ADSC transdifferentiation, and to examine factors influencing transdifferentiation, including transcription factors, epigenetics, and signaling pathways. Exploring and understanding the mechanisms are a precondition for developing and applying novel cell therapies.

PMID- 30302097 TI - Prediction of cognitive dysfunction after resuscitation - a systematic review. AB - Cardiac arrest (CA) due to cardiovascular disease is the leading cause of death in developed countries. It is estimated that over 350,000 people in Europe suffer from out-of-hospital cardiac arrest. According to the literature, the longer the episode of cardiac arrest, the greater the risk of cognitive impairment, especially short-term memory, as well as immediate and delayed recall. Other common dysfunctions include attention deficits and executive function disorders. The aim of this systematic review was to summarize current research on cognitive impairment in patients after sudden cardiac arrest. The electronic databases PubMed/MEDLINE, OVID, Web of Science, and EBSCO were searched using the following key words: 'sudden cardiac arrest', 'out-of-hospital cardiac arrest', 'cognitive function', 'cognitive impairment', 'functional outcome', 'cardiopulmonary resuscitation'. The most recent studies from the last 7 years (2011-2018) were included. Cognitive disorders occurred in a broad range of cases: from 13% to even 100%. In one study, cognitive deficits did not occur at all. Amongst the reviewed articles only two studies were carried out on a large group of patients. The remaining studies were conducted on a small group of respondents; therefore there was no possibility to generalize the results to the entire population. The areas in which the most cognitive impairment occurred were memory, executive functions and visual-motor skills. One of the conclusions derived from the reviewed literature is the importance of continuous training of cognitive functions, especially for people with cardiovascular risk. PMID- 30302098 TI - Acute, total occlusion of the left main stem: coronary intervention options, outcomes, and recommendations. AB - Introduction: Acute, total occlusion of the unprotected left main stem (uLMo) in acute coronary syndrome (ACS) patients is a catastrophic event often accompanied by sudden cardiac death (SCD) and/or cardiogenic shock (CS) with high mortality rates and limited methods of successful treatment. Emergent, surgical and percutaneous revascularization has been reported before, yet comprehensive data remains scarce. Aim: To examine emergency percutaneous coronary intervention (PCI) outcomes in ACS cases presenting with uLMo. Material and methods: Data on 23 subjects undergoing primary PCI in uLMo cases were analyzed. The primary end point was in-hospital death; secondary end-points were successful salvage of coronary anatomy and 90-day major cardiac adverse events (MACE). Results: About 40% of LM occlusion cases presented following successful on-site cardio-pulmonary resuscitation (CPR). Of all patients arriving for treatment the occluded LM was successfully opened and stented in ~90% of cases. CS was present in > 85% of cases, and circulatory support in the form of intra-aortic balloon pump and/or extracorporeal membrane oxygenation systems was applied in every eligible case (~80%). The in-hospital death rate was 56%, mostly including individuals requiring prior CPR. At 6 months, additional MACE rates were low at 8.7%. Conclusions: We found that uLMo ACS cases often present with preceding CPR and mostly in manifest CS. Coronary salvage is generally successful, yet uLMo even with optimal present day complex treatment yields quite high mortality rates. This is especially true for patients receiving prior CPR. In surviving patients, however, 6-month MACE rates are acceptable. PMID- 30302099 TI - Procedural advantages of a novel coronary stent design with ultra-thin struts and bioabsorbable abluminal polymer coating in an all-comers registry. AB - Introduction: The implications of novel drug-eluting stent (DES) design modifications including ultra-thin struts and new concepts of polymer coating for procedural efficacy are still unknown. Aim: To evaluate procedural efficacy and short-term safety of a novel DES design. Material and methods: In this all-comers registry, 407 consecutive patients were enrolled upon undergoing percutaneous coronary interventions (PCI) with the thin-strut bioabsorbable abluminal polymer coated SYNERGY stent. These patients were then compared with the previous 407 patients undergoing PCI performed by the same interventionalists using currently established second-generation DES (Promus Element plus, Xience prime, Resolute Integrity). Several clinical and procedural data were compared, and the coronary artery complexity was assessed by the American College of Cardiology/American Heart Association classification and SYNTAX Score. Results: The study population consisted of 814 patients. A total of 859 Synergy stents were deployed in 480 target vessels in the Synergy group (n = 407), and 904 stents in 469 vessels in the second-generation DES group (n = 407). Coincidentally, target lesions in the Synergy group (A 2.7%, B1 13.8%, B2 38.6%, C 45.0%) were more complex (p < 0.01) than those in the second-generation DES group (A 4.9%, B1 18.7%, B2 42.3%, C 34.2%). In cases with severe lesions (B2/C), the median contrast agent amount and fluoroscopy time were significantly lower in the Synergy group, indicating improved deliverability (110 ml vs. 150 ml; p < 0.01 and 7.2 min vs. 9.1 min; p = 0.01). Rates of in-hospital major adverse cardiovascular events were comparable between the two groups. Conclusions: In an all-comers, real-world PCI population, novel stent design modifications including ultra-thin struts and abluminal bioabsorbable polymer coating are associated with improved procedural performance. PMID- 30302100 TI - Temporal changes in the pattern of invasive angiography use and its outcome in suspected coronary artery disease: implications for patient management and healthcare resources utilization. AB - Introduction: Invasive coronary angiography (CAG), the 'gold standard' in coronary artery disease (CAD) diagnosis, requires hospitalization, is not risk free, and engages considerable healthcare resources. Aim: To assess recent (throught out 10 years) evolution of 'significant' (>= 50% stenosis(es)) CAD prevalence in subjects undergoing CAG for CAD diagnosis in a high-volume tertiary referral center. Material and methods: Anonymized medical records were compared for the last vs. the first 2-years of the decade (June 2007 to May 2018). Referrals for suspected CAD were 2067 of 4522 hospitalizations (45.7%) and 1755 of 5196 (33.8%) respectively (p < 0.001). Results: The median patient age (64 vs. 68 years) and the prevalence of heart failure (24.1% vs. 42.2%) increased significantly (p < 0.001). The CAG atherosclerotic lesions, for all stenosis categories (< 50%; >= 50%; >= 70%; occlusion(s)), were significantly more prevalent in men. The proportion of subjects with any atherosclerosis on CAG increased (80.7% vs. 77.6%, p = 0.015). However, in the absence of any gross change in, for instance, the fraction of women (40.4% vs. 41.8%), the proportion of CAGs with significant CAD (lesion(s) >= 50%) decreased from 55.2% in 2007/2008 to below 1 in every 2 angiograms (48.9%) in 2017/2018 (p < 0.001). This unexpected finding occurred consistently across nearly all CAG referral categories. Conclusions: Despite more advanced age and a higher proportion of subjects with 'any' coronary atherosclerosis on CAG, the likelihood of a 'negative' angiogram (lesion(s) < 50%; no further evaluation/intervention) has increased significantly over the last decade. The exact nature of this phenomenon requires further investigation, particularly as a reverse trend would be expected with the growing role (and current high penetration) of contemporary non-invasive diagnostic tools to rule out significant CAD. PMID- 30302101 TI - Does the effectiveness of recanalization of chronic occlusion depend on the location of the obstruction? AB - Introduction: In past studies, it has been questioned whether success of recanalization of chronic total occlusion (CTO) depends on the location of the occlusion - the circumflex artery (Cx) was considered as the most difficult to open. Aim: To determine whether the effectiveness of recanalization of CTO depends on the location of the obstruction. Material and methods: From January 2011 to January 2016, a single operator dedicated to chronic total occlusions performed in our center 357 procedures on 337 patients. Results: Among 337 patients included in the study, 83.4% were male. Mean age was 62.8 +/-9.3 years. Most of the patients had hypertension (86.4%) and hyperlipidemia (99.4%), and 28.8% of them had diabetes. The most frequently opened artery was the right coronary artery (RCA; 52.4%), followed by the left anterior descending artery (LAD; 29.4%), and last the Cx (18.2%). The mean J-CTO score was comparable between the three groups. The success rate of recanalization of CTO was similar for all arteries: 84.5% in the RCA, 81.9% in the LAD and 89.2% in the Cx (overall p = 0.437). Neither procedural complications nor adverse events depended on the location of the CTO. Conclusions: Our study shows the same efficacy of CTO procedures of all epicardial arteries. We did not observe that effectiveness of recanalization of CTO depends on the location of the obstruction. PMID- 30302102 TI - Association of mean platelet volume and red blood cell distribution width with coronary collateral development in stable coronary artery disease. AB - Introduction: The prognostic value of hematological indices in cardiovascular diseases and the association between these parameters and cardiovascular conditions have been established in the literature. Aim: In this study, we aimed to investigate the relation of mean platelet volume (MPV), MPV to platelet ratio (MPR) and red cell distribution width (RDW) with degree of coronary collateral development (CCD) in stable coronary artery disease (CAD) subjects with established critical coronary artery stenosis. Material and methods: A total of 306 patients with stable angina pectoris undergoing coronary arteriography were enrolled and divided on the basis of the development of CCD into two groups: a group with adequate CCD (n = 214) and a group with impaired CCD (n = 92). Routine complete blood count and biochemical parameters were measured before coronary arteriography. Results: The MPV and MPR levels were significantly higher in the inadequate CCD group (10.5 +/-1.8 fl vs. 8.7 +/-1.9 fl, p < 0.001 and 0.06 +/ 0.08 vs. 0.05 +/-0.07, p = 0.036). Patients with inadequate CCD had significantly higher RDW levels compared to patients with adequate CCD (15.5 +/-1.7% vs. 15.0 +/-1.9%, p = 0.01). MPV and RDW were significantly associated with Rentrop collateral grading (r = -0.523, p < 0.001 and r = -0.239, p < 0.001, respectively), whereas the association with MPR was not significant. An MPV value greater than 9.95 fl, determined with ROC curve analysis, had 71% sensitivity and 70% specificity in predicting inadequate CCD. An RDW greater than 14.3% has 71% sensitivity and 53% specificity in selecting patients with adequate CCD. Conclusions: The present study suggests that MPV and MPR may be associated with the degree of collateral development in chronic stable CAD. However, the negative association of RDW with inadequate CCD, in combination with previous contradictory reports, raises a doubt about the possible value of RDW in stable CAD. Although these parameters may be affected by various conditions, a high MPV may lead clinicians to suspect possible inadequate collateral development in stable CAD patients. PMID- 30302103 TI - Clinical factors predicting blood pressure reduction after catheter-based renal denervation. AB - Introduction: Renal denervation (RD) can lead to a significant and sustained decrease in mean values of arterial blood pressure (BP). However, there is still a subset of patients without a significant BP drop after RD (non-responders). Aim: To compare characteristics of RD responders to RD non-responders and to identify the clinical predictors of BP reduction. Material and methods: Thirty one patients with diagnosed resistant hypertension underwent RD. Three years after RD the analysis of BP reduction was performed in regard to the baseline patient characteristics. Results: After 3 years' follow-up a 10% or more reduction of systolic baseline BP was observed in 74% of patients. Ten percent or more reduction of diastolic baseline BP was observed in 71% of patients. Among responders we observed the following risk factors: hypercholesterolemia in 70%, body mass index (BMI) > 30 kg/m2 in 55%, diabetes mellitus in 35%, current smoking in 5%. Comorbidity included coronary artery disease (CAD) in 30%, cardiomyopathy in 10%, chronic obstructive pulmonary disease (COPD) in 10%, renal insufficiency in 10%, and ventricular arrhythmia in 5%. Among non-responders we observed the following risk factors: hypercholesterolemia in 38%, diabetes mellitus type 2 in 38% and BMI > 30 kg/m2 in 86%. Comorbidity included CAD in 50% and cardiomyopathy in 13% of patients. Conclusions: A 10% reduction of systolic baseline BP was observed in 74% of patients 3 years after renal denervation. Clinical factors like COPD, chronic kidney disease 3a, female sex and hypercholesterolemia increase the chances of effective reduction of BP. PMID- 30302104 TI - Increased risk profile in the treatment of patients with symptomatic degenerative aortic valve stenosis over the last 10 years. AB - Introduction: Currently, Cardiology Centres are overfilled with patients with degenerative aortic valve stenosis (DAS), usually eldery, with severe concommittant comorbidities, who are referred for further decisions and possible intervention. Aim: To evaluate changes in the risk profile of patients with severe DAS admitted to the cardiology department a decade ago compared with patients currently being admitted. Material and methods: We retrospectively evaluated all patients admitted with confirmed severe DAS, hospitalized during 2005-2006 (group I: 140 patients) and in 2016 (group II: 152 patients), admitted for aortic valve intervention. A standard transthoracic echocardiogram, cardiovascular symptom and risk factor distribution, perioperative risk with the logistic EuroSCORE II and STS mortality scores were obtained. Results: Patients in group II were significantly older (p < 0.001), had more cardiovascular risk factors, and more often presented with atrial fibrillation (27% vs. 11.4%, p = 0.001), renal impairment (34.9% vs. 22.8%; p = 0.024), severe lung disease (17.1% vs. 2.1%, p < 0.001), and extracardiac arteriopathy (40.1% vs. 17.8%, p < 0.001). The aortic valve area (AVA) (p = 0.356), mean-transvalvular pressure gradient (p = 0.215), and left ventricular ejection fraction (p = 0.768) were similar in both groups. However, the prevalence of pulmonary hypertension, severe mitral regurgitation, and low-flow, low-gradient DAS were 3.1-, 8.4- and 1.84-fold more frequent in group II than group I. The percentages of subjects with EuroSCORE II and STS scores >= 4% in 2005-2006 were 7.1% and 6.4%, as compared to 27% and 26.3% in 2016 (both p < 0.001). 22% of patients in 2016, as compared to 31% in 2005/2006, were considered ineligible for DAS intervention. Conclusions: In just a decade, the risk profile of patients admitted with DAS has increased hugely, mainly due to older age, accumulation of comorbidities and more advanced disease at presentation. Although transcatheter aortic valve intervention has expanded the indications for intervention in high-risk patients, the number of patients disqualified from interventional treatment remains high. PMID- 30302105 TI - Silent ischemic brain lesions detected by multi-slice computed tomography are associated with subclinical atrial fibrillation in patients with cardiac resynchronization therapy. AB - Introduction: There is insufficient research on the relationship between subclinical atrial fibrillation (SCAF) and silent ischemic brain lesions (IBLs). Aim: To investigate the relationship between SCAF and silent IBLs in patients with cardiac resynchronization therapy (CRT). Material and methods: Of 720 CRT implanted patients in our department between 2012 and 2018, 121 patients who underwent elective cranial multi-slice computed tomography (MSCT) during their follow-up were included in our study. Atrial high-rate episodes (AHRE) were detected by the CRT device. Subclinical atrial fibrillation was defined as asymptomatic AHRE longer than 6 min and shorter than 24 h. A cranial MSCT scan was performed using a 128-section scanner with contiguous 2-5 mm axial images. Patients were divided into two groups - with and without silent IBL. Results: Silent IBLs were detected in 21 (17.4%) of 121 patients with CRT. Ischemic brain lesion presence was found to be associated with age, CHA2DS2-VASc score, left ventricular (LV) ejection fraction (EF), hypertension and SCAF in univariate analysis (p < 0.05). In multivariate regression analysis, presence of SCAF and LVEF were found to be independent parameters predicting the risk of silent IBLs. According to this analysis, the presence of SCAF and every 1% decrease in LVEF were found to increase the risk of silent IBL by 3.5 times and 14.8%, respectively. Conclusions: Subclinical atrial fibrillation is independently associated with silent IBL presence. Patients with CRT should be closely monitored for SCAF. Patients diagnosed with SCAF should be evaluated for IBL development and treated with the appropriate oral anticoagulant. PMID- 30302106 TI - Comparison of clinical and echocardiographic outcomes and quality of life in patients with severe mitral regurgitation treated by MitraClip implantation or treated conservatively. AB - Introduction: The most common alternative method of treatment for patients with severe mitral regurgitation (MR) is the implantation of a MitraClip device. Aim: To evaluate clinical and echocardiographic outcomes and quality of life (QoL) in patients with severe secondary MR, disqualified from surgical intervention, treated by implantation of a MitraClip in comparison to conservative therapy. Material and methods: A total of 33 patients were included. Patients were stratified by treatment method: group A, MitraClip implantation (n = 10); group B, conservative treatment (n = 23). Clinical, echocardiographic, and QoL (EQ-5D 3L, SF-12v2 Health Survey) characteristics were compared at baseline and at follow-up of 8.0 +/-2.3 months. Results: In group A, 2 deaths were observed: one patient died 7 days after MitraClip implantation, and the second patient died 4 months after the procedure. No cases of rehospitalization were reported. In group B, 4 (17.4%) deaths and 6 (26.1%) hospitalizations were reported. After MitraClip implantation a significant reduction of the NYHA class (p = 0.02), decrease in grade of MR (p = 0.01), vena contracta width (p = 0.006), effective regurgitant orifice area (EROA) (p = 0.003), regurgitant volume (p = 0.03) and end-diastolic left ventricle diameter (p = 0.02) as well as an improvement in QoL were reported. There were no significant changes in the NYHA class and QoL in the group treated conservatively. In those patients, we observed increased intercommissural mitral annulus diameter (p = 0.03), left atrium diameter (p = 0.002), and right ventricle dimension (p = 0.008), more severe tricuspid regurgitation (p = 0.02) and lower mitral annular plane systolic excursion (p = 0.01). Conclusions: Patients with severe secondary MR treated with the MitraClip achieved a significant reduction in symptoms and MR grade, as well as an improvement in QoL, as compared to patients treated conservatively.

AB - Eosinophilic fasciitis is an uncommon connective tissue disorder that affects patients of all ages, resulting in significant morbidity. Systemic corticosteroids can induce remission of disease. However, there is no universally accepted treatment ladder for eosinophilic fasciitis. This case series evaluates treatment efficacy in patients with eosinophilic fasciitis seen at Wake Forest University Department of Dermatology outpatient clinics. Patient charts were screened using ICD-9 diagnosis code 710.9 (unspecified diffuse connective tissue disease) to identify patients with eosinophilic fasciitis (n=10) seen at our institution. Patients were treated for an average 24 months with a combination of methotrexate and prednisone therapy, unless one or both were contraindicated, with each medication tapered conservatively to prevent disease flares. Alternate treatments included mycophenolate mofetil with prednisone, azathioprine with prednisone, prednisone monotherapy, and methotrexate monotherapy. Disease remission off therapy and on low-dose therapy was 66 and 70%, respectively. Our first-line therapy of concomitant methotrexate and prednisone is well-tolerated and effective for managing patients with eosinophilic fasciitis. Our study was limited to cases seen at a single academic institution. PMID- 30302115 TI - The biosimilars journey: current status and ongoing challenges. AB - Biosimilar products are already approved and marketed in several countries. The Food and Drug Administration has approved ten different biosimilars, and the European Medicines Agency has approved 40. Even though this scenario has provided important experience with biosimilar products, there are still challenges and unanswered questions. Up to now, a good amount of knowledge has been gathered in order to support the importance of the totality of evidence and the construction of a biosimilarity exercise for regulatory approval. In addition, the extrapolation of indications has been proved viable when a careful analysis is performed. The models for clinical trials and the use of the most sensible populations have been extensively discussed, and there is apparent homogeneity in manufacturer choices for study designs. However, some challenges remain. The lack of regulatory harmony, especially concerning naming, the marketed intended copies, the interchangeability, and the biosimilars in orphan diseases are some of those and are the focus of discussion in this review. PMID- 30302116 TI - Comparative Proteomic Analysis of Two Differently Extracted Coptis chinensis in the Treatment of Type 2 Diabetic Rats. AB - Coptis chinensis (CC) is widely used to treat diabetes in traditional Chinese medicine due to its significant hypoglycemic and hypolipidemic effects. It was reported that CC powders are more effective than CC decoctions. In this study, a rat model of type 2 diabetes was established and treated with supercritical extracted CC and gastric juice extracted CC, respectively. Body weight, fasting plasma insulin, insulin resistance index, and lipid profiles were measured along with oral glucose tolerance tests (OGTTs). In addition, the levels of plasma proteins were compared between type 2 diabetic rats and CC-treated rats using an iTRAQ-based quantitative proteomic analysis. The results showed that the plasma levels of triglyceride (TC), total cholesterol (TG), and low-density lipoprotein (LDL) in rats of both CC-treated groups were significantly decreased. In addition, the proteomic analysis identified 929 proteins, while 15 proteins were selected from these 929 proteins based on their expression levels and bioinformatic results. Among these 15 proteins, 9 proteins (IGF-1, Igfbp4, Igfbp 6, Igfals, C2, C4, Cfi, Prdx-2, and Prdx-3) were upregulated in the two CC treated groups, while 6 proteins (Pla2g7, Pcyox1, ApoC-1, ApoC-3, ApoB-100, and ApoE) were downregulated. The functions of these proteins are associated with glucose metabolism, insulin action, immunity, inflammation, lipid metabolism, oxidation, and antioxidation. The two differently extracted CC did not show significant differences in terms of their treatment efficacy. This research expanded our understanding on the therapeutic effects and mechanisms of CC in the treatment of type 2 diabetes. PMID- 30302117 TI - Major Depression in Chinese Medicine Outpatients with Stagnation Syndrome: Prevalence and the Impairments in Well-Being. AB - Stagnation syndrome, a diagnostic entity in traditional Chinese medicine (TCM), has been long regarded as the TCM counterpart of major depression in Western medicine. The study investigated the prevalence of major depression among stagnation syndrome patients and evaluated their well-being and functioning outcomes. In total, 117 patients diagnosed with stagnation syndrome were measured using Stagnation Scale, the Patient Health Questionnaire-9 (PHQ-9), and the Body Mind-Spirit Well-Being Inventory. Results indicate major depression among stagnation syndrome patients was characterized by a high co-occurrence rate and worse physical, mental, and functional outcomes. More than one-quarter (26.5%) of the patients met the DSM-V diagnostic criteria for major depression and over half (53%) exceeded the PHQ-9 cutoff (score above 10) for moderate/severe depression symptoms. The wellness of the stagnation syndrome patients was worse (M = 298.2, SD = 66.5) than that of the general population (M = 360.9, SD = 79.9), with a large Cohen's d value of 0.9. The "wellness outlook" of the depressed stagnation syndrome patients appeared grimmer (M = 252.3, SD = 52.2). The correlation between stagnation and depression was higher for affective symptoms than somatic symptoms. Physical distress did not mediate the relationship between stagnation and daily functioning. These might suggest that stagnation syndrome and major depression may share some similar psychological mechanisms. PMID- 30302118 TI - Chinese Medicinal Herbs in the Treatment of Diabetic Cognitive Impairment: A Systematic Review and Meta-Analysis. AB - Background: Diabetic cognitive impairment (DCI), a serious complication of diabetes mellitus (DM), is gaining more acceptance and attention. The learning and memory function of diabetics always decreases. Traditional Chinese medicine (TCM) has been demonstrated to be effective in treating the symptoms in China, and thereinto Chinese medicinal herbs (CMH) are the most widely used. The objective of the present study was to review and analyze the existing data about reducing the symptoms in CMH treatment for DCI. Methods: Electronic literature databases (PubMed, EMBASE, CNKI, SinoMed, and Wan fang) were searched for randomized controlled trials conducted in China, comparing CMH with western medicines in the treatment of DCI, up to April 1, 2018. We applied standard meta analytic techniques to analyze data from papers that reached acceptable criteria. Result: Nine randomized controlled trials (n = 576) on CMH were included. We found moderate evidence that CMH used alone or in combination with western medicines was more effective than western medicines alone in reliving the symptoms for DCI (total effective rate, odds radio (OR) = 4.64 (2.60, 8.29), and 95% confidence interval, P<0.00001). Besides, CMH along or in combination with western medicines showed more beneficial effects on Montreal Cognitive Assessment (MoCA) scale (mean difference (MD) = 1.31(0.75, 1.87), P<0.00001), Mini-Mental State Examination (MMSE) scale (MD = 2.07 (0.86, 3.28), P<0.00001, and TCM symptom score (TCMSS) (MD = -4.89 (-8.44, -1.34), P = 0.007). Most of the included studies showed that there was not a significant difference in the adverse events. Conclusions: These findings demonstrated that CMH used alone or in combination with western medicines were apparently better than western medicines alone in the treatment of DCI. Because of the poor quality of the studies that were available for the present meta-analysis, further researches are still needed to support these early findings. PMID- 30302119 TI - Biological Evaluation of Different Extracts of Aerial Parts of Nepeta deflersiana and Standardization of Active Extracts Using 8-Epi-7-Deoxyloganic Acid and Ursolic Acid by Validated HPTLC Method. AB - Nepeta deflersiana (Lamiaceae) is a well-known medicinal plant that grows in Saudi Arabia. This plant is used in Saudi and Yemeni folk medicine as an anti inflammatory, carminative, and antirheumatic agent. In order to prove its use in folk medicine, four different extracts from the aerial parts of the plant: petroleum ether, chloroform, ethyl acetate, and n-butanol extracts were subjected to biological assays to screen PPARalpha and PPAR Upsilon agnostic, antioxidant, anti-inflammatory, and cytotoxic activities. Ethyl acetate and n-butanol extracts of N. deflersiana NDEE and NDBE, respectively, showed a decrease in oxidative stress and inhibition of both NF-kB and iNOS activities with no cytotoxic effects on four human cancer cell lines. Both active extracts were standardized using two bioactive metabolites which were isolated from the aerial parts of the same plant [8-epi-7-deoxyloganic acid (compound 1) and Ursolic acid (compound 2)] by developing a validated HPTLC method. It was found to provide a sharp and compact band of compound 1 at Rf = 0.07 and Rf = 0.57 for compound 2, using chloroform, methanol, and formic acid (8.9:0.8:0.3, v/v/v) as mobile phase at 550 nm. Compounds 1 and 2 were found in NDEE by 9.59 %, w/w, and 84.63 %, w/w, respectively, and by 11.97 %, w/w, and 21.26 %, w/w, respectively, in NDBE. PMID- 30302120 TI - Oplopanax horridus: Phytochemistry and Pharmacological Diversity and Structure Activity Relationship on Anticancer Effects. AB - Oplopanax horridus, well-known as Devil's club, is probably the most important ethnobotanical to most indigenous people living in the Pacific Northwest of North America. Compared with the long history of traditional use and widespread distribution in North America, the study of O. horridus is relatively limited. In the past decade, some exciting advances have been presented on the phytochemistry and pharmacological diversity and structure-activity relationship on anticancer effects of O. horridus. To date, no systematic review has been drafted on the recent advances of O. horridus. In this review, the different phytochemicals in O. horridus are compiled, including purified compounds and volatile components. Animal and in vitro studies are also described and discussed. Especially, the potential structural-activity relationship of polyynes on anticancer effects is highlighted. This review aimed to provide comprehensive and useful information for researching O. horridus and finding potential agents in drug discovery. PMID- 30302121 TI - Effects of exenatide versus insulin glargine on body composition in overweight and obese T2DM patients: a randomized controlled trial. AB - Background: Weight loss, especially fat mass reduction, helps to improve blood glucose control, insulin sensitivity, and beta-cell function. This study aimed to compare the effect of exenatide and glargine on body composition in overweight and obese patients with type 2 diabetes (T2DM) who do not achieve adequate glycemic control with metformin. Methods: We performed a prospective, randomized study of 37 overweight or obese patients with T2DM who had inadequate glycemic control with metformin. The patients were treated with either exenatide or glargine for 16 weeks. Dual-energy X-ray absorptiometry was used to assess body composition. Results: Post-intervention weight, body mass index (BMI), waist circumference, body mass, and fat mass were lower in patients treated with exenatide, while weight and BMI significantly increased with glargine. Reductions in weight, BMI, body fat mass, and percent fat mass (except for gynoid) were greater with exenatide than with glargine, and percent lean tissue (other than the limbs) increased with exenatide. In all body regions except for the limbs, fat mass decreased with exenatide to a greater extent than lean tissue. Glucose control, insulin resistance, and beta-cell function were not different between the treatment groups. Conclusions: For overweight and obese patients whose T2DM was inadequately controlled with metformin, exenatide and glargine achieved similar improvements in glycemic control, insulin sensitivity, and beta-cell function.However, exenatide produced better weight and fat mass reduction, which were beneficial for blood glucose control. Our findings may guide the selection of appropriate drugs for glycemic and weight control. Trial registration: NCT02325960, registered 25 December 2014. PMID- 30302123 TI - A New Approach for Advertising CTR Prediction Based on Deep Neural Network via Attention Mechanism. AB - Click-through rate prediction is critical in Internet advertising and affects web publisher's profits and advertiser's payment. The traditional method of obtaining features using feature extraction did not consider the sparseness of advertising data and the highly nonlinear association between features. To reduce the sparseness of data and to mine the hidden features in advertising data, a method that learns the sparse features is proposed. Our method exploits dimension reduction based on decomposition, takes advantage of the attention mechanism in neural network modelling, and improves FM to make feature interactions contribute differently to the prediction. We utilize stack autoencoder to explore high-order feature interactions and use improved FM for low-order feature interactions to portray the nonlinear associated relationship of features. The experiment shows that our method improves the effect of CTR prediction and produces economic benefits in Internet advertising. PMID- 30302124 TI - Risk factors for mortality in the late amputation of necrotizing fasciitis: a retrospective study. AB - Background: Necrotizing fasciitis (NF) is a rapidly progressive infectious disease that primarily involves the fascia and subcutaneous tissue. If not promptly treated, it can lead to morbidity as well as mortality. It can affect any part of the body, most commonly the extremities. Early and aggressive surgical treatment is the proper way of management. The purpose of this study was to identify the risk factors for mortality in late amputation among NF patients that may be used in routine clinical practice to prevent mortality. Methods: A retrospective cohort study of hospitalized patients with NF was conducted in a tertiary teaching hospital in Taiwan between March 2015 and March 2018. All collected data were statistically analyzed. Results: A total of 582 patients with NF were included; 35 of them had undergone amputation (7 primary and 28 late amputations), with a 6% amputation rate. Thirteen amputated patients still died eventually (all in the late amputation group). Significant risk factors for mortality identified in the late amputation group included hemorrhagic bullae (p = 0.001, OR 4.7, 95% confidence interval (CI) 2.68-8.69), peripheral vascular disease (p < 0.001, OR 3.2, 95% CI 1.12-10.58), bacteremia (p = 0.021, OR 2.87, 95% CI 2.07-5.96), and Laboratory Risk Indicator of Necrotizing Fasciitis (LRINEC) score > 8 (p < 0.001, OR 1.97, 95% CI 1.28-4.61). Vibrio vulnificus was the main causative organism based on our study, but the microbiology results showed no significant correlation. Conclusion: NF patients with hemorrhagic bullae, comorbidity with peripheral vascular disease, presence of bacteremia, or LRINEC score > 8 should receive early and primary amputation in order to prevent mortality. PMID- 30302122 TI - MicroRNAs from plants to animals, do they define a new messenger for communication? AB - MicroRNAs (miRNAs), a class of single-stranded non-coding RNA of about 22 nucleotides, are potent regulators of gene expression existing in both plants and animals. Recent studies showed that plant miRNAs could enter mammalian bloodstream via gastrointestinal tract, through which access a variety of tissues and cells of recipients to exert therapeutic effects. This intriguing phenomenon indicates that miRNAs of diet/plant origin may act as a new class of bioactive ingredients communicating with mammalian systems. In this review, in order to pinpoint the reason underlying discrepancies of miRNAs transmission from diet/plant to animals, the pathways that generate miRNAs and machineries involved in the functions of miRNAs in both kingdoms were outlined and compared. Then, the current controversies concerning cross-kingdom regulations and the potential mechanisms responsible for absorption and transfer of diet/plant-derived miRNAs were interpreted. Furthermore, the hormone-like action of miRNAs and the intricate interplay between miRNAs and hormones were implicated. Finally, how these findings may impact nutrition and medicine were briefly discussed. PMID- 30302125 TI - UK clinical experience up to 52 weeks with linaclotide for irritable bowel syndrome with constipation. AB - Background: Linaclotide, a guanylate cyclase C agonist, has been shown in clinical trials to improve symptoms of irritable bowel syndrome with constipation (IBS-C). Here we report data from a real-world study of linaclotide in the UK. Methods: This 1-year, multicentre, prospective, observational study in the UK enrolled patients aged 18 years and over initiating linaclotide for IBS-C. The primary assessment was change from baseline in IBS Symptom Severity Scale (IBS SSS) score at 12 weeks, assessed in patients with paired baseline and 12-week data. Change from baseline in IBS-SSS score at 52 weeks was a secondary assessment. Adverse events were recorded. Results: In total, 202 patients were enrolled: 185 (91.6%) were female, median age was 44.9 years (range 18.1-77.2) and 84 (41.6%) reported baseline laxative use. Mean (standard deviation) baseline IBS-SSS score was 339 (92), with most patients (n = 129; 66.8%) classified as having severe disease (score ?300). In patients with paired data, there was a significant mean (95% confidence interval) decrease in IBS-SSS score from baseline to 12 weeks [-77.0 (-96.3, -57.7); p < 0.001; n = 124] and baseline to 52 weeks [-70.7 (-95.0, -46.5); p < 0.001; n = 76]. Overall, 174 adverse events were reported in 77 (38.1%) patients, most commonly diarrhoea (n = 54; 26.7%), abdominal pain (n = 21; 10.4%) and abdominal distension (n = 13; 6.4%). Conclusion: Linaclotide significantly improved IBS-SSS score at 12 and 52 weeks. These results provide insights into outcomes with linaclotide treatment over 1 year in patients with IBS-C in real-world clinical practice. PMID- 30302126 TI - Food and Drug Administration guidances on biosimilars: an update for the gastroenterologist. AB - The management of inflammatory bowel disease (IBD), a significant cause of morbidity in the United States (US), has been revolutionized over the last two decades by the introduction of biologic therapies. These include antitumor necrosis factor alpha (TNF-alpha) agents. Since 2016, five biosimilar TNF-alpha inhibitors have been approved by the US Food and Drug Administration (FDA) for use in the treatment of IBD. The FDA has published a series of guidance documents related to the evaluation, licensing, and approval of biosimilars. The aim of this review is to provide an overview of these FDA guidances and the issues associated with biosimilars in the US. PMID- 30302127 TI - Drug holiday in patients with polycystic liver disease treated with somatostatin analogues. AB - Background: Somatostatin analogues (SAs) reduce liver volume and relief symptoms in polycystic liver disease (PLD). Its effect wears off after continuing therapy suggesting development of SA tolerance in patients on chronic therapy. We postulate that a drug holiday resensitizes the liver to its acute pharmacological effects. Therefore, this study examines the liver volume-reducing effect of SAs after a drug holiday. Methods: Patients were identified from the International PLD Registry and included in our analysis when (1) treated with SAs during two cycles separated by a drug holiday and (2) height-adjusted total liver volume (hTLV) was available at start and end of each cycle. For our primary outcome we compared the effect of SAs (in % per 6 months) on hTLV between the first and second treatment cycle. Results: In 34 patients, initial liver volume-reducing effect was similar to that after rechallenge [-2.6% per 6 months (interquartile range, -3.8-0.8) versus -1.6% per 6 months (interquartile range, -3.1-1.1), p = 0.510]. Cessation of treatment led to a rebound effect, but liver volume remained stable compared with the baseline with intermittent therapy in responders to SA [ 0.6% (interquartile range, -7.4-5.7) after 46.5 months]. Conclusions: PLD patients treated with SAs benefit from retreatment after a drug holiday. The significant increase of liver volume after cessation of treatment complicates widespread use of a drug holiday as new treatment strategy. Our results contribute to a better understanding of the pharmacological effect of SAs and help to identify patients who might benefit. PMID- 30302128 TI - Effect of plano-valgus foot posture on midfoot kinematics during barefoot walking in an adolescent population. AB - Background: Plano-valgus is a common alteration of the paediatric foot, characterized by valgus hindfoot, foot pronation and drop of the medial longitudinal arch. Despite their importance in the diagnosis and classification of plano-valgus foot condition, little information is available on functional alterations of the major joints spanning the medial longitudinal arch - i.e. midtarsal and tarso-metatarsal. Aim of the study was to provide objective description of the alterations in plano-valgus midfoot joints with respect to those in an age-matched normally-developed feet population. Methods: Twenty adolescents (13.3 +/- 0.8 years) with bilateral plano-valgus feet underwent clinical examination and were gait-analysed via a validated 4-segment foot model. This allowed to measure static foot posture, kinematics of the main foot joints, and medial longitudinal arch deformation during walking at comfortable speed. Range of motion and temporal profiles of joint rotations were compared to those from a control population of age-matched adolescents with normally-developed feet. Results: The plano-valgus midtarsal joint was more dorsiflexed, everted and abducted than that in the control group, and showed reduced sagittal-plane RoM (plano-valgus = 15.9 degrees; control = 22.2 degrees; P < 0.01). The tarso metarsal joint was more plantarflexed and adducted, and showed larger frontal plane RoM. The MLA showed larger RoM and was lower throughout the stance phase of the gait cycle. Conclusion: Significant postural and kinematic alterations are present at the midtarsal and tarso-metarsal joints of adolescents with plano valgus feet. Objective identification and quantification of plano-valgus foot alterations, via non-invasive gait-analysis, is relevant to improving the diagnosis of this condition and to evaluating the effect of conservative treatments and of surgical corrections by different techniques. PMID- 30302129 TI - Combined effect of glycemic and blood pressure control on diabetic retinopathy among Chinese with type-2 diabetes mellitus. AB - Background: To explore the associations of glycemic and blood pressure (BP) control with diabetic retinopathy (DR), with special focus on whether different combinations of categories of these two interventions are additive. Methods: A community-based survey including 913 patients with known type-2 diabetes mellitus (T2DM) was conducted in Suzhou, China. Retinal photographs were graded for the presence of DR using the Airlie House classification system. BP and blood hemoglobin A1c (HbA1C) levels were measured by standardized protocols. Binary logistic regression models were established to examine the associations of risk factors with DR. Results: The overall prevalence of any DR was 18.0% [95% confidence interval (95% CI) 15.5-20.6%] in this population. Stratified by conventional control thresholds, lower levels of either systolic blood pressure (SBP, < 140 mmHg) or HbA1C (< 7.0%) were not significantly associated with decreased susceptibility to DR, while patients simultaneously with lower HbA1C and SBP levels demonstrated 43% reduced likelihood of developing DR [adjusted odds ratio (OR) = 0.57, 95% CI 0.33-0.99, P = 0.045)], comparing with those with both higher levels of HbA1C (>= 7.0%) and SBP (>= 140 mmHg). Meanwhile, the group achieved intensive HbA1C (< 6.5%) and SBP (< 120 mmHg) control goals were found to have the smallest OR, but failed in yielding statistical significance (P = 0.10). Conclusions: In this community-based DR screening study of Chinese adults with T2DM, combination but not individual of lower SBP (< 140 mmHg) and HbA1C (< 7.0%) levels, were suggested to be associated with a significantly reduced likelihood of having DR. PMID- 30302130 TI - Primary cilium and glioblastoma. AB - Glioblastoma (GBM) represents the most common, malignant and lethal primary brain tumour in adults. The primary cilium is a highly conserved and dynamic organelle that protrudes from the apical surface of virtually every type of mammalian cell. There is increasing evidence that abnormal cilia are involved in cancer progression, since primary cilia regulate cell cycle and signalling transduction. In this review, we summarize the role of primary cilium specifically with regard to GBM, where there is evidence postulating it as a critical mediator of GBM tumorigenesis and progression. This opens the way to the application of cilia targeted therapies ('ciliotherapy') as a new approach in the fight against this devastating tumour. PMID- 30302131 TI - Effect of statins on oxidative DNA damage in diabetic polyneuropathy. AB - Oxidative stress induces nerve damage in type 2 diabetes mellitus and leads to diabetic polyneuropathy (DPN) and can affect the DNA and antioxidant status. Statins have pleiotropic, protective effects on the peripheral nerves of patients with diabetes. The aim of this study was to determine the effects of ezetimibe/simvastatin and rosuvastatin on DNA damage in patients with DPN. This randomized, double-blind, placebo-controlled, clinical trial comprised outpatients from Guadalajara, Mexico. The inclusion criteria were either gender, age 35-80 years, type 2 diabetes, glycated hemoglobin <=10%, diabetic polyneuropathy stage 1/2, and signed informed consent. Patients who were taking antioxidant therapy or statins, had hypersensitivity to drugs, experienced organ failure, were pregnant or breastfeeding, or had other types of neuropathy were excluded. We assigned patients to placebo, ezetimibe/simvastatin 10/20 mg, or rosuvastatin 20 mg, and the primary outcomes were 8-hydroxy-2'-deoxyguanosine (8 OHdG) for DNA damage, 8-oxoguanine-DNA-N-glycosilase (hOGG1) for DNA repair, and superoxide dismutase (SOD). Seventy-four patients were recruited. Nine patients were included as negative controls. There were no differences in 8-OHdG between the healthy subjects (4.68 [3.53-6.38] ng/mL) and the DPN patients (4.51 [1.22 9.84] ng/mL), whereas the hOGG1 level was 0.39 (0.37-0.42) ng/mL in the healthy subjects and 0.41 (0.38-0.54) ng/mL in patients with DPN at baseline (p = 0.01). SOD decreased significantly in patients with DPN (5.35 [0.01-17.90] U/mL) compared with the healthy subjects (9.81 [8.66-12.61] U/mL) at baseline (p < 0.001). No significant changes in DNA biomarkers were observed in any group between baseline and final levels. We noted a rise in hOGG1 in patients with DPN, without modifications after treatment. There was a slight, albeit insignificant, increase in SOD in patients who were on statins. PMID- 30302132 TI - Engineering the hard-soft tissue interface with random-to-aligned nanofiber scaffolds. AB - Tendon injuries can be difficult to heal and have high rates of relapse due to stress concentrations caused by scar formation and the sutures used in surgical repair. Regeneration of the tendon/ligament-to-bone interface is critical to provide functional graft integration after injury. The objective of this study is to recreate the tendon-to-bone interface using a gradient scaffold which is fabricated by a one-station electrospinning process. Two cell phenotypes were grown on a poly-epsilon-caprolactone nanofiber scaffold which possesses a gradual transition from random to aligned nanofiber patterns. We assessed the effects of the polymer concentration, tip-to-collector distance, and electrospinning time on the microfiber diameter and density. Osteosarcoma and fibroblast cells were seeded on the random and aligned sections of scaffolds, respectively. A random-to aligned cocultured tissue interface which mimicked the native transition in composition of enthesis was created after 96 h culturing. The results showed that the microstructure gradient influenced the cell morphology, tissue topology, and promoted enthesis formation. This study demonstrates a heterogeneous nanofiber scaffold strategy for interfacial tissue regeneration. It provides a potential solution for mimicking transitional interface between distinct tissues, and can be further developed as a heterogeneous cellular composition platform to facilitate the formation of multi-tissue complex systems. PMID- 30302133 TI - Treatment and evaluation of dysphagia rehabilitation especially on suprahyoid muscles as jaw-opening muscles. AB - In our aging society, the number of patients with dysphagia, which is associated with disease and aging, is rapidly increasing. The swallowing reflex is a complex process that involves coordinated contractions of swallowing muscles. Many researchers have reported that age-related changes, such as frailty and sarcopenia, affect swallowing muscles and contribute to the decline in the swallowing function. Thus, simple, non-invasive evaluation methods and exercises for swallowing muscles in elderly patients with dysphagia are important. Anterior superior hyolaryngeal elevation during swallowing results from contractions of the suprahyoid muscle, which plays a primary role in opening the upper esophageal sphincter, along with relaxation of the cricopharyngeal muscle and laryngeal closure. Thus, many researchers have studied methods for evaluating and augmenting suprahyoid muscles. On the other hand, some researchers have reported on dysphagia rehabilitation focused on jaw-opening actions, because hyolaryngeal elevation muscles correspond with jaw-opening muscles. In this study, we describe a new dysphagia evaluation method and an exercise that focuses on suprahyoid muscles with application of jaw-opening actions. PMID- 30302134 TI - Effects of blue-light irradiation during dental treatment. AB - In dentistry, blue light is widely used for tooth bleaching and restoration procedures involving composite resin. In addition, many dentists use magnification loupes to enable them to provide more accurate dental treatment. Therefore, the use of light is indispensable in dental treatment. However, light can cause various toxicities, and thermal injuries caused by light irradiation are regarded as particularly important. In recent years, the eye damage and non thermal injuries caused by blue light, the so-called "blue light hazard", have gained attention. Unfortunately, much of the research in this field has just begun, but our recent findings demonstrated that blue-light irradiation generates reactive oxygen species (ROS) and induces oxidative stress in oral tissue. However, they also showed that such oxidative stress is inhibited by antioxidants. There have not been any reports that suggested that the ROS-induced phototoxicity associated with blue-light irradiation causes direct clinical damage, but some disorders are caused by the accumulation of ROS. Therefore, it is presumed that it is necessary to suppress the accumulation of oxidative stressors in oral tissues during treatment. In the future, we have to promote discussion about the suppression of phototoxicity in dentistry, including concerning the use of antioxidants to protect against phototoxic damage. PMID- 30302135 TI - Mastication as a tool to prevent cognitive dysfunctions. AB - Mastication as we all know has always been related to its primary function of digestion, but little do we know that it produces an enhancing effect on general health, especially the cognitive performance related aspects of memory. Recent studies have shown its association with activation of various brain regions, however little is known about its effects on neuronal activity in these specified regions. According to the enormous evidences collected so far, mastication has proved to be effective in conducting huge amount of sensory information to the brain, and maintaining learning and memory functions of hippocampus. Therefore it is essential that we maintain normal occlusion and preserve the masticatory function as long as possible to prevent the attenuation of hippocampus, caused by occlusal disharmony and reduced mastication. We provide an overview on how mastication activates various cortical areas of the brain and how an increase in the cerebral blood oxygen level of hippocampus and prefrontal cortex (PFC) accentuates the learning and memory process. We also justify why maintaining and establishing a normal occlusion is important from neurological point of view. PMID- 30302136 TI - Association of feeding behavior with jaw bone metabolism and tongue pressure. AB - In recent decades, the eating habits of children and adolescents have undergone many changes due to the diversification of lifestyles worldwide. Reduced masticatory function in growing animals results in changes in the mandible, including a decrease in bone mass. However, the influence of different eating behaviors on jaw bone metabolism (e.g., the palatal palate) during the growth period is not fully understood. In addition, recent clinical studies reported that masticatory performance is positively related to tongue pressure in adults, but no consensus has been reached regarding whether tongue pressure is related to masticatory performance in children. This review summarizes current findings related to these issues, focusing on the influence of different feeding behaviors on jaw bone metabolism, including the development of tongue pressure. Consumption of a soft diet had a negative impact on jaw bone metabolism in the maxilla and mandible of rats; however, mastication of a hard diet recovered the collapsed equilibrium of bone turnover caused by a soft diet during growth. Tongue pressure is closely associated with an increase in masticatory performance in children. Peak maximum tongue pressure is reached earlier in women than in men. Before reaching adulthood, women require intervention to increase their peak tongue pressure. PMID- 30302138 TI - Introduction to Kampo medicine for dental treatment - Oral pharmacotherapy that utilizes the advantages of Western and Kampo medicines. AB - Kampo medicine is a medical system that has been systematically organized based on the reactions of the human body. At present, in Western, herbal medicines means the whole herbal product. It is being called Kampo medicine as a medicinal drug in Japan. Since 2012, the "National Health Insurance Drug Price Standards Related to Dental Treatment" published by the Japan Dental Association have included seven Kampo formulations. In 2015, the Japan Dental Association sent a "Kampo Education Plan for Dentistry" to all dental universities in Japan. Furthermore, the Japanese Society of Oral Therapeutics and Pharmacology compiled a summary of "Evidence for Kampo Treatment in the Field of Oral Surgery." In addition, the phrase "including wakan-yaku" was included in the draft core model curriculum for dental education in 2016. Thus, Kampo medicine is expected to rapidly spread to the field of dental care and dental medical education. Therefore, the training of dentists with knowledge of both Western and Oriental medicine is required for the treatment of oral pain, periodontal disease, stomatitis, xerostomia, and other complaints concerning oral health. It is our hope that this paper provides a footing for dentists who wish to learn about Kampo medicine and incorporate it into clinical practice. PMID- 30302137 TI - Structural features, processing mechanism and gene splice variants of dentin sialophosphoprotein. AB - Dentin sialophosphoprotein (DSPP) plays an important role in the formation of dentin. Understanding its structure and function would provide important insights into the regulation of dentin mineralization. For the past 15 years, we have been studying DSPP-derived proteins isolated from pig dentin. Porcine DSPP is synthesized and secreted by odontoblasts and processed into three proteins, i.e., dentin sialoprotein (DSP), dentin glycoprotein (DGP), and dentin phosphoprotein (DPP), by bone morphogenetic protein 1 and matrix metalloproteinase-20 and -2. DSP is a proteoglycan that forms covalent dimers, DGP is a phosphorylated glycoprotein, and DPP is a highly phosphorylated intrinsically disordered protein with genetic polymorphisms. Furthermore, DPP is not detected in dental pulp. This is possibly due to the existence of two mRNA variants of the DSPP gene: one that encodes the DSP region alone and another that encodes full-length DSPP. The mRNA variant encoding DSP alone is expressed in dental pulp and odontoblasts, but the variant encoding full-length DSPP is predominantly expressed in odontoblasts and barely in dental pulp. PMID- 30302139 TI - Lateral laparoscopic adrenalectomy in patients with previous abdominal surgery - single-center experience. AB - Introduction: Lateral transabdominal adrenalectomy (LTA) is the most common minimally invasive technique used to treat patients with adrenal tumors. Aim: To analyze intra-operative and post-operative complications and reasons for conversion to open surgery in patients who underwent LTA and had previous abdominal surgery. Material and methods: Five hundred and nineteen patients underwent LTA in our center between 2005 and 2016. We identified a study group of 150 patients, with previous abdominal surgery. We analyzed the frequency of intra operative and post-operative complications and the reasons for conversion from laparoscopic to open adrenalectomy. Results: The patients' mean age was 58; they underwent LTA due to hormonally active tumors (n = 79, 53%) and non-functioning adrenal tumors (n = 71, 47%). The size of adrenal lesions ranged from 20 mm to 90 mm. Seventy-eight (52%) adrenal lesions were found in the right adrenal gland, and 72 (48%) lesions in the left adrenal gland. The mean operating time was 130 min. The mean stay in hospital was five days. The intra-operative complications included blood pressure fluctuations (n = 32), abnormal vascular supply of the adrenal glands causing difficulties with dissections (n = 3), and respiratory problems (n = 1). Two (1.3%) patients had post-operative bleeding at the site of removed adrenal glands; 1 patient had an exacerbation of asthma postoperatively. Of the 150 patients analyzed, 3 (2%) required conversion to open adrenalectomy. The conversions were not caused by abdominal adhesions. Conclusions: Lateral transabdominal adrenalectomy is feasible and safe in patients with previous abdominal surgery. In our study, conversion from laparoscopic to open adrenalectomy was not caused by abdominal adhesions. PMID- 30302140 TI - Adrenal cysts - optimal laparoscopic treatment. AB - Introduction: Adrenal cysts develop in up to about 0.2% of the overall population. They may account for up to 11% of all pathologies of adrenal glands. Aim: Is laparoscopic resection of adrenal cysts a method for the treatment of these pathologies? Material and methods: In the years 2010-2017, a total of 27 patients underwent surgery due to adrenal cysts; those included 18 (66.7%) women and 9 (33.3%) men aged 29 to 84 years (mean age: 42.7). Cyst diameter ranged from 55 to 130 mm. After exclusion of hormonal hyperactivity, parasitic cysts, or, to the best possible extent, cancer lesions, patients were qualified for adrenal sparing laparoscopic surgery. Results: All patients were subjected to laparoscopic surgery. Cystic wall resection was performed in 15 (55.6%) patients while adrenalectomy was performed in the remaining 12 (44.4%) patients. The decision regarding the extent of the surgery was made intraoperatively. Histopathological assessment revealed pathological adrenal lesions in as few as 3 (11.1%) patients, with the rest of the study population, i.e. 24 (88.9%), presenting with normal adrenal tissue. Conclusions: Laparoscopic resection of adrenal cysts appears to be recommendable as a method for the treatment of these pathologies. It is simpler than adrenalectomy and associated with low risk of any pathological lesion remaining within the adrenal gland following careful intraoperative assessment by an experienced surgeon. PMID- 30302141 TI - Short- and long-term results of laparoscopic adrenalectomy for Conn's syndrome. AB - Introduction: The primary treatment of Conn's syndrome (CS) is laparoscopic adrenalectomy and aims to normalize arterial blood pressure and biochemical parameters. Aim: To analyse short- and long-term results of laparoscopic adrenalectomy for Conn's syndrome (CS). Material and methods: The analysis included 44 consecutive patients, who underwent laparoscopic adrenalectomy between 2004 and 2015 for CS. We analysed short- and long-terms results of operations. All patients were followed up 6 and 24 months after surgery to determine changes in the biochemical parameters, and clinical regression of arterial hypertension. We also evaluated the aldosteronoma resolution score (ARS) in predicting the resolution of hypertension. Results: No conversions were needed. Complications occurred in 5 (11.4%) patients. Preoperative hypokalaemia and hypernatraemia were present in 83.4% and 15.8% of patients, respectively. After surgery, both hypokalaemia and hypernatraemia resolved in all patients. At the follow-up 6 months after the surgery, only 11.3% of patients had complete remission (CR) of hypertension. In 43.2% of cases we observed partial remission (PR). After 24 months CR was found in 13.6% of patients, 45.5% patients fulfilled criteria for PR, and 29.5% of patients changed the group of remission comparison to the first follow-up visit. Only 50% of patients with an ARS of 4 or 5 points achieved CR 6 months after surgery. Conclusions: Laparoscopic adrenalectomy is a safe method of treatment for CS. Although it effectively eliminates electrolyte imbalance, it does not allow for the CR of hypertension in the majority of patients, especially in the elderly group. We did not find ARS to be an effective tool in predicting postoperative resolution of hypertension. PMID- 30302142 TI - Neovascularization after ischemic conditioning of the stomach and the influence of follow-up neoadjuvant chemotherapy thereon. AB - Introduction: Esophagectomy and reconstruction remain the optimal treatment for patients with resectable esophageal cancer. Neovascularization after ischemic conditioning of the stomach before esophagectomy is a laparoscopic procedure which may potentially reduce gastric conduit ischemia. Aim: To investigate the influence of ischemic conditioning on neovascularization along the greater curvature of the stomach and to explore the effect of neoadjuvant chemotherapy on neovascularization after ischemic conditioning. Material and methods: Staging laparoscopy was performed before the main resection procedure; during this procedure ischemic conditioning was performed. Samples taken from the human stomach were divided into 3 groups: group A - patients after ischemic conditioning with a delay of 30-45 days after left gastric artery (LGA) ligation (n = 4); group B - patients who were undergoing neoadjuvant chemotherapy with a delay of 90-140 days after left gastric artery ligation (n = 4); and control group C - patients without ischemic conditioning (n = 7). Results: After ischemic conditioning with a delay of 30-45 days, the count of neovessels along the greater curvature of the stomach increased from 5.4 +/-0.7 in the control group to 17.5 +/-0.9 in a low-power field of view (LPF) in group A and increased still further on average to 19.8 +/-10.4 in group B. Conclusions: Left gastric artery ligation only is a sufficient procedure for ischemic conditioning of the stomach. Neovascularization along the greater curvature is a continuous process that depends on delay time. Neoadjuvant therapy has no influence on the effect of neovascularization. PMID- 30302143 TI - Defunctioning ileostomy and mechanical bowel preparation may contribute to development of low anterior resection syndrome. AB - Introduction: Laparoscopic surgery is an approved technique in colorectal cancer treatment. Functional and quality-of-life studies have revealed significant changes in faecal continence. Aim: To assess the incidence and risk factors of low anterior resection syndrome (LARS) in patients undergoing rectal resections for cancer. Material and methods: We enrolled patients undergoing rectal resections in a general surgery department of a university hospital. The primary outcomes were the Jorge-Wexner scale and the LARS score 6 months after the end of treatment. The secondary outcomes were the risk factors for LARS development. Results: Fifty-six patients were included; 15 (26%) developed major LARS and 10 (18%) had minor LARS at 6 months. In univariate analysis the risk factors were: preoperative radiotherapy (p < 0.001, OR = 11.9, 95% CI: 2.98-47.48); shorter distance of the tumour from the anal verge (p = 0.001, OR = 0.69, 95% CI: 0.55 0.86); bowel preparation (p = 0.01, OR = 6.27, 95% CI: 1.51-26.07); low anterior rectal resection (p = 0.01, OR = 17.07, 95% CI: 1.86-156.83); and protective ileostomy (p = 0.001, OR = 15.97, 95% CI: 4.07-61.92). The risk factors for a higher Jorge-Wexner score in univariate analysis were greater diameter of tumour (p = 0.035), radiotherapy (p = 0.001), shorter distance from the anal verge (p = 0.002), bowel preparation (p = 0.042), low anterior rectal (LAR) (p = 0.01), ileostomy (p = 0.001), perioperative complications (p = 0.032), and readmission within 30 days (p = 0.034). In the multivariate analysis, readmissions and perioperative complications were significant. Conclusions: In addition to typically described risk factors, two new ones have been identified. Mechanical bowel preparation and defunctioning ileostomy may also contribute to LARS development. However, due to the limitations of this study our observations require further confirmation in future trials. PMID- 30302144 TI - Use of inflammatory markers in the early detection of infectious complications after laparoscopic colorectal cancer surgery with the ERAS protocol. AB - Introduction: Thanks to laparoscopy and enhanced recovery protocols (ERAS) it is possible to shorten hospitalization. Therefore, it seems reasonable to search for new early markers of infectious complications in order to select patients who are prone to development of complications. Aim: To assess the usefulness of serum levels of C-reactive protein, interleukin-6 and procalcitonin as early indicators of infectious complications in patients after laparoscopic colorectal surgery with ERAS. Material and methods: The prospective analysis included consecutive patients who underwent laparoscopic colorectal cancer resection. The following parameters were included in the analysis: C-reactive protein (CRP), interleukin 6 (IL-6) and procalcitonin measured on postoperative days (PODs) 1, 2, 3. Patients were divided into two groups: uncomplicated (group 1) and complicated (group 2). The difference in levels of the markers and the dynamics of changes observed in both groups were analyzed. Results: Group 1 comprised 34 patients, and group 2 consisted of 17 patients. A significant increase of both absolute values and delta increments on all postoperative days was noted. ROC curve analysis showed that the best cut-off values indicating an infectious process were: CRP 129 mg/l on POD3 (92% sensitivity/80% specificity), IL-6 of 78 pg/ml on POD2 (91% sensitivity/97% specificity) and PCT 0.24 ng/ml on POD3 (93% sensitivity/68% specificity). Conclusions: Our study showed that regular measurement of all analyzed markers in the early postoperative days may be beneficial in the detection of postoperative infectious complications. Further studies are needed to fully assess the role of routine biochemical measurements in the postoperative period after laparoscopic surgery with the ERAS protocol. PMID- 30302145 TI - Postoperative complications are associated with worse survival after laparoscopic surgery for non-metastatic colorectal cancer - interim analysis of 3-year overall survival. AB - Introduction: Postoperative morbidity after colorectal resections for cancer remains a significant problem. Data on the influence of complications on survival after laparoscopic colorectal resection are still limited. Aim: To analyze the impact of postoperative complications on long-term survival after radical laparoscopic resection for colorectal cancer. Material and methods: Two hundred and sixty-five consecutive non-metastatic colorectal cancer patients undergoing laparoscopic colorectal resection for cancer were included in the analysis. The entire study group was divided into two subgroups based on the occurrence of postoperative complications. Group 1 included patients without postoperative morbidity and group 2 included patients with complications. The primary outcome was overall survival. Results: Median follow-up was 45 (IQR: 34-55) months. Group 1 consisted of 187 (70.5%) patients and group 2 comprised 78 (29.5%) patients. Studied groups were comparable in terms of sex, age, body mass index, ASA class, cancer staging, localization of the tumor and operative time. Patients in group 1 had significantly better overall 3-year survival compared to those with complications (84.9% vs. 69.8%, p = 0.022). Kaplan-Meier curves showed significantly improved survival rates in patients without complications compared with complicated cases. The Cox proportional multivariate model showed that postoperative complications (HR = 2.83; 95% CI: 1.35-5.92; p = 0.0058) and AJCC III (HR = 3.17; 95% CI: 1.52-6.6; p = 0.0021) were independent predictors of worse survival after laparoscopic colorectal cancer surgery. Conclusions: Our analysis of interim results after 3 years confirms that complications after laparoscopic colorectal cancer surgery have an impact on survival. For this reason, these patients should be carefully monitored after surgery aiming at early detection of recurrence. PMID- 30302146 TI - Comparison of resection site of standardized laparoscopic hepatic tumor resection. AB - Introduction: The degree of difficulty in laparoscopic hepatic resection (LHR) was higher in tumors involving the suprahepatic segments than other sites. However, thanks to surgical instruments and procedures being improved and standardized, LHR can be performed safely in all regions. Aim: We report our standardized surgical techniques and outcomes in a series of patients undergoing LHR in our hospital and analyze the surgical outcomes, particularly with regard to the site of resection. Material and methods: We retrospectively analyzed data from 238 patients who underwent standardized laparoscopic partial hepatic resection between 2010 and 2017. In standardized LHR, the operator formed a triangle with the laparoscope in the center, maintaining a co-axial position by changing the port where the laparoscope was inserted. Results: Operative time for the resection of tumors of the right hepatic lobe was 202 +/-92 min and 140 +/ 104 min for tumors of the left hepatic lobe (p = 0.0024); intraoperative blood loss was 80 +/-170 ml and 19 +/-127 ml, respectively (p = 0.0016). No differences were found in the surgical outcomes between the various segments of the right hepatic lobe. In the left hepatic lobe, operative time was significantly shorter with laparoscopic tumor resection in segment III (p = 0.0023). Conclusions: During standardized LHR, a better field of vision with the greater ease can be established during resection of the left hepatic lobe compared to that of the right hepatic lobe. Nonetheless, LHR of the right lobe can be performed safely using various surgical instruments and techniques. PMID- 30302147 TI - Randomized trial of umbilical incisional hernia in high-risk patients: extraction of gallbladder through subxiphoid port vs. umbilical port after laparoscopic cholecystectomy. AB - Introduction: Trocar site incisional hernia (TSIH) is one of the most common complications of laparoscopic surgery. Using the umbilical port as a common hole for removing the gallbladder in laparoscopic cholecystectomy is more likely to lead to TSIH than other ports. Thus, extracting the gallbladder through other ports may reduce the incidence of TSIH. Aim: To ascertain whether extraction of the gallbladder through the subxiphoid port is more beneficial for reducing umbilical incisional hernia than the umbilical port. Material and methods: From April 2014 to March 2017, a randomized clinical trial was conducted among patients with high risk of incisional hernia and accepted for three-port laparoscopic cholecystectomy (TLC) in our department. 182 patients with indications of cholecystectomy were allocated randomly to group A (subxiphoid port) and group B (umbilical port). Data collection was carried out on operative time, postoperative pain, hospital stay, wound infection and TSIH in the early postoperative course, and at 1, 10, and 24 months after surgery. Results: The incidence of TSIH in group A was lower than that in group B (4.9% vs. 14.6%; odds ratio = 8.02; 95% CI: 2.15-47.6; p < 0.001). The mean operative time of group A was significantly shorter than that of group B (35 +/-15.16 min vs. 42 +/-14.58 min, p < 0.01). There was no significant difference in wound infection rate between group A and group B (p = 0.068). The data of hospital stay (p = 0.428) and postoperative pain (p = 0.349) of all analyzed patients were similar in the two groups. Conclusions: Extraction of the gallbladder through the subxiphoid port can reduce umbilical incisional hernia in high-risk patients effectively. PMID- 30302148 TI - The Surgical Apgar Score and frailty as outcome predictors in short- and long term evaluation of fit and frail older patients undergoing elective laparoscopic cholecystectomy - a prospective cohort study. AB - Introduction: Frailty increases the risk of poor surgical outcomes in the older population. Some intraoperative factors may also influence the final result and can be evaluated. The Surgical Apgar Score (SAS) is a simple system predicting postoperative mortality and morbidity. However, the utility of the SAS remains unknown in fit and frail older patients undergoing elective laparoscopic cholecystectomy due to benign gallbladder diseases. Aim: To evaluate the usefulness of the SAS in predicting 30-day morbidity and 1-year mortality in older fit and frail patients undergoing elective laparoscopic cholecystectomy. Material and methods: Consecutive patients (>= 70 years) were enrolled in the prospective study. The Comprehensive Geriatric Assessment (CGA) was used to diagnose frailty. Logistic regression was conducted to investigate the association between the scores and the outcomes. Results: The study included 144 consecutive older patients with a median age of 76 (range: 70-91) years. The prevalence of frailty was 44.4%. The 30-day mortality and morbidity were 0% and 11.8%, respectively. The 1-year mortality was 6.3% and 7 out of 9 occurred in the frail group. SAS < 7 points was identified as an independent predictor of 30-day postoperative morbidity (OR = 5.1; 95% CI: 1.5-18.1). Age > 85 years (OR = 1.9; 95% CI: 1.2-16.4) and frailty (OR = 3.4; 95% CI: 1.1-19.3) were predictors of 1 year mortality. Conclusions: Laparoscopic cholecystectomy can be safely performed in older fit and frail patients. The SAS, not age, turned out to be the most important predictor of 30-day morbidity. Frailty and age > 85 years were predictors of 1-year mortality. Older patients with SAS < 7 points should be followed meticulously in order to diagnose and treat potential complications early on. PMID- 30302149 TI - A promising technique for easier single incision laparoscopic cholecystectomy: needle grasper traction of gallbladder. AB - Introduction: Laparoscopic cholecystectomy (LC) is the primary treatment method for benign gallbladder diseases. Single incision laparoscopic cholecystectomy (SILC) was reported to be superior in terms of work return, cosmetic results, and post-operative pain, but limited maneuver capacity and overlapping of hand tools are technical difficulties associated with SILC that endanger patient safety. Aim: To perform SILC using a needle grasper for gallbladder traction, thus simplifying the dissection of Calot's triangle. Material and methods: The files of patients who underwent elective LC for gallbladder stone and polyps in general surgery clinics between December 2013 and December 2014 were analyzed retrospectively. The patients were divided into two groups: needle-grasper assisted SILC (nSILC) and conventional laparoscopic cholecystectomy (CLC). Age, gender, height, weight, body mass index, visual analog scale (VAS) scores, ASA score, duration of operation, duration of post-operative hospital stay, complications, drain use, conversion to open and conventional technique, and oral feeding beginning time were analyzed. Results: There were no per-operative or post-operative complications in either of the groups, and no significant differences were found between the groups in terms of complications. The mean duration of the operation was significantly longer in the nSILC group. There was no difference between the groups in terms of hospital stay. The mean visual analogue scale (VAS) scores in conventional nSILC were significantly lower for all hours. The patient satisfaction in terms of cosmetic results was better in the nSILC group. Conclusions: Needle-grasper-assisted SILC reduces the number of tools that need to be held by surgeons; it also provides safe dissection, better cosmetic results, and less post-operative pain in elective cases. PMID- 30302150 TI - Fasting and postprandial acyl and desacyl ghrelin and the acyl/desacyl ratio in obese patients before and after different types of bariatric surgery. AB - Introduction: The mechanism underlying beneficial outcomes of bariatric surgery still remains unclear. Especially little is known about hormonal and metabolic changes induced by the novel bariatric procedure mini gastric bypass (MGB). Aim: To evaluate pre- and post-prandial changes in both ghrelin isoforms in obese patients without diabetes and cardiovascular complications treated with MGB, sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) surgery. Material and methods: From 45 patients initially enrolled in the study, 23 persons completed a one-year follow-up period. Venous blood for acyl and desacyl ghrelin (AG and DAG) as well as other metabolic assays was collected 3 months before and 6 and 12 months after bariatric surgery (MGB, RYGB, SG) - in the fasting state and 2 h after the consumption of a standard 300 kcal-mixed meal (Nutridrink standard, Nutricia). Results: AG and DAG levels (both fasting and prandial) as well as AG/DAG ratio did not change after 6 and 12 months in MGB and RYGB groups. In the SG group we observed a significant decrease in fasting and postprandial DAG levels and consecutively an increase in the fasting AG/DAG ratio after 6 and 12 months. Six months after surgery we observed some differences between carbohydrate metabolism measures in the MGB group (lower HbA1c, HOMA-IR and fasting insulinaemia) in comparison to the rest of the participants, but 12 months after each type of surgery body mass index and indices of carbohydrate and lipid metabolism did not differ. Conclusions: The results of our study demonstrate that all studied bariatric procedures can successfully reduce overall body weight and suggest also that the mechanisms of weight loss and improvement in carbohydrate and lipid metabolism after all three types of surgery are independent of ghrelin and the acyl/desacyl ghrelin ratio. PMID- 30302151 TI - Comparative study of video-assisted thoracoscopic surgery versus open thymectomy for thymoma and myasthenia gravis. AB - Introduction: Thymectomy is the preferred standard treatment in younger non thymoma patients with myasthenia gravis as well as in patients with early stage thymoma. Total thymectomy by median sternotomy has been the surgical approach since resection of the thymus with video-assisted thoracoscopic surgery (VATS). Aim: To compare the clinical outcomes of VATS thymectomy with conventional open thymectomy for neoplastic and non-neoplastic thymic diseases. Material and methods: Forty patients underwent thymectomy between October 2012 and January 2016. Fifteen patients were male and 25 patients were female. The mean age was 40.3 +/-17.7 years. Seventeen (55%) patients underwent VATS thymectomy and 23 (45%) patients underwent an open procedure. We retrospectively reviewed the data of the patients and compared these two techniques. Results: The mean tumor size was 5.17 +/-3.2 cm in the thymoma group (VATS 2.5 +/-2.4 cm vs. open access 4.7 +/-3.7 cm). None of the patients experienced a myasthenic crisis. Conversion to thoracotomy was required in 1 patient in the VATS group due to bleeding from the right internal mammary artery; therefore, the conversion rate was 2.5% among all the patients. No mortality occurred in either group. No significant difference was found in the perioperative blood loss, operative time or pain visual analogue scale scores. On the other hand, regarding postoperative drainage, duration of chest tube drainage and length of hospital stay, VATS thymectomy yielded better results and the differences were significant. Conclusions: Video-assisted thoracoscopic surgery thymectomy can be performed for both neoplastic and non neoplastic thymic diseases with minimal morbidity and mortality. PMID- 30302152 TI - Minimally invasive repair of pectus carinatum by modification of the Abramson technique. AB - Introduction: The minimally invasive pectus carinatum surgery described by Abramson has been performed in many centers. We modified the "sub-muscular tunnel creation" part of the original Abramson technique. Aim: To compare the operative time between the original Abramson technique and a lightly modified approach. Material and methods: A retrospective review of 84 patients who underwent minimally invasive repair of pectus carinatum deformity between July 2008 and November 2017 was performed. We applied two different techniques, the original Abramson technique and the modified technique. Sixty-eight patients - 49 (72%) males and 19 (28%) females - underwent minimally invasive repair of a pectus carinatum deformity as described by Abramson (Abramson group). Sixteen patients - 13 (81%) males and 3 (19%) females - were operated on by our modified Abramson technique at our institution (Modified group). Results: Eighty-four patients were included in this study: 68 patients from the Abramson group and 16 patients from the Modified group. There was no significant difference between the groups with respect to preoperative demographic features, including median age and sex. Median operative time was significantly shorter in the Modified group than the Abramson group (43 min, range: 32-54 min) in the Modified group vs. 30 min (range: 20-35 min) in the Abramson group (p < 0.001). Conclusions: This article describes a modification of a surgical technique that is safely and easily used in minimally invasive correction of pectus carinatum deformities, with minimal complications, high satisfaction rates and shorter operative time. PMID- 30302153 TI - Minimally invasive injection laryngoplasty in the management of unilateral vocal cord paralysis after video-assisted mediastinal lymph adenectomy. AB - Introduction: Video-assisted mediastinal lymphadenectomy (VAMLA) is a valuable tool for invasive staging of the mediastinum. Unilateral vocal cord paralysis (UVCP) may occur in patients following VAMLA and may result in secretion retention within the lungs, atelectasis and associated infectious situations such as pneumonia. Minimally invasive injection laryngoplasty (ILP) is the treatment of choice in UVCP. Aim: To evaluate the efficacy and success of acute minimally invasive injection laryngoplasty for patients with UVCP following VAMLA. Material and methods: Patients with the symptom of dysphonia following VAMLA were reviewed. All of the patients had UVCP according to the video laryngoscopy examination and had symptoms of aspiration and ineffective coughing. The Voice Handicap Index (VHI) questionnaire and maximum phonation time (MPT) were measured. Minimally invasive ILP was performed under general anesthesia with 1 cm of hyaluronic acid. Results: There were 525 consecutive non-small cell lung cancer (NSCLC) patients who underwent VAMLA. Five (0.95%) of the patients had UVCP and were suffering from aspiration during oral intake and ineffective coughing reflex. Maximum phonation time (MFT) was measured before and after ILP, and the results were 7.1 +/-1.6 and 11.1 +/-2.3 s, respectively (p < 001). The Voice Handicap Index-10 (VHI-10) score was 30.4 +/-4.7 and 13.4 +/-3.5 (p < 0.01), respectively. Patients underwent surgical lung resection. There was no morbidity or mortality. Conclusions: Unilateral vocal cord paralysis may occur as a complication of VAMLA. ILP may be an active tool for treating UVCP before anatomical lung resection to avoid potential morbidities. Successful management of this complication with multidisciplinary team work may encourage the use of VAMLA more frequently. PMID- 30302154 TI - An investigation on endoscopic laryngopharyngeal surgery and related outcomes. AB - Introduction: Robotic surgery is used in Europe and the US for oropharyngeal/hypopharyngeal cancers. Although robots can successfully perform procedures that are too delicate for surgeons and quickly learn accurate techniques, robotic surgery is not still authorized for the craniocervical region in Japan. In Japan, endoscopic laryngopharyngeal surgery (ELPS) is widely performed. Because oropharyngeal/hypopharyngeal cancer can be resected at an early stage, we have contributed to an improvement in the survival rate. Aim: To analyze clinical outcomes and risk factors of postoperative cervical lymph node metastases after ELPS. Material and methods: Fifty-two patients with 71 superficial oropharyngeal/hypopharyngeal cancers were included. A Sato-type arcuation laryngoscope was inserted, and oropharyngeal and hypopharyngeal fields were secured. We have recently been performing head and neck surgery using only a flexible endoscope because gastroscopy and arcuation-type forceps interfere with each other. Results: The 5-year survival rate was 95.2%. The risk factors of lymph node metastases were examined. The depth of the tumor significantly affected lymph node metastases. Conclusions: With a favorable 5-year survival rate and low functional impairment, ELPS is an extremely effective form of treatment. It can provide a clear field of view in the hypopharynx and has a low cost; hence, it should be further developed as a treatment method. PMID- 30302155 TI - Comparison of outcomes of conventional transcanalicular laser dacryocystorhinostomy and modified transcanalicular laser dacryocystorhinostomy. AB - Introduction: Transcanalicular laser DCR (TL-DCR) approaches have been developed for the formation of a fistula between the nasal cavity and the lacrimal sac to ensure the continuity of the lacrimal drainage system over the years. However, the success rate of TL-DCR has varied widely. Aim: To evaluate and compare the success rates of conventional transcanalicular multidiode laser dacryocystorhinostomy and modified transcanalicular multidiode laser dacryocystorhinostomy. Material and methods: Ninety-one eyes of 91 adult patients admitted with epiphora and diagnosed with chronic dacryocystitis were included in the study. The participants were divided into two groups. Group 1 consisted of 55 patients who were treated with conventional transcanalicular laser dacryocystorhinostomy. Group 2 consisted of 36 patients to whom the same surgical procedure was applied with the difference of nasal mucosa excision prior to laser osteotomy. The groups' intraoperative surgical ostium size, perioperative and postoperative complications, operative times and success rates were compared. Results: The mean follow-up periods for each group were 8.88 +/-2.99 months and 10.28 +/-4.47 months, respectively (p = 0.077). Intraoperative mean surgical ostium sizes were 31.85 +/-14.98 mm2 and 42.25 +/-18.09 mm2, respectively (p = 0.004). The mean operation time in group 1 was significantly shorter compared to group 2 (18.55 +/-4.05 min and 24.44 +/-3.18 min, respectively, p = 0.0001). The overall success rate was 65.45% in group 1 and 75.00% in group 2 (p = 0.335). Conclusions: Although the surgical ostium area was significantly greater in group 2, there was no significant difference in surgical success and patient satisfaction rates between the two groups. PMID- 30302156 TI - Single-anastomosis duodeno-ileal - new revision procedure in a patient with insufficient weight loss after sleeve gastrectomy. AB - Laparoscopic sleeve gastrectomy (LSG) is one of the most popular and effective bariatric surgical procedures worldwide. The effect of LSG is mostly dependent on the restrictive mechanism, which makes it more vulnerable to failure. Failing of bariatric procedure is not uncommon and occurs in 6% to 23%. In case of weight loss failure, there are no hard recommendations on the choice of the redo procedure. One of the most novel options, introduced in 2007, relatively simple to perform following LSG is single-anastomosis duodenoileal bypass. Herein we describe surgical technique and history of a patient with inadequate weight loss after laparoscopic sleeve gastrectomy, who underwent single-anastomosis duodenoileal bypass. PMID- 30302157 TI - Minimally invasive techniques and indocyanine angiography in anterior abdominal wall reconstruction after multiple laparotomies. AB - Anterior abdominal wall reconstruction surgery in patients who have undergone multiple laparotomies is associated with a high risk of complications. For this reason, minimally invasive surgery techniques are used to avoid abdominal compartment syndrome, to enhance wound healing and to reduce postoperative pain and blood loss. This paper presents a case of a patient who was admitted to the Department of General Surgery in Puck Hospital as a result of extensive anterior abdominal wall deformation with an end descending colostomy. A single-stage procedure was performed: specifically, digestive tract reconstruction followed by anterior abdominal wall reconstruction using intraoperative angiography of indocyanine green in infrared light. PMID- 30302158 TI - Endoscopic removal of an impacted wooden toothpick in the wall of the sigmoid colon. AB - Most ingested foreign bodies usually pass through the gastrointestinal tract without any complications. Sharp foreign bodies such as a wooden toothpick may cause severe complications, leading to an acute abdomen. They may also cause mild, non-specific gastrointestinal symptoms without significant findings. We describe a case of a 60-year-old man initially diagnosed with a foreign body impacted into the wall of the rectosigmoid junction upon screening colonoscopy. Incidentally, ingestion of the wooden toothpick 6 months before admission and the presence of recurrent fever and lower abdominal pain were confirmed in the patient's history. Our video case study demonstrates the successful endoscopic removal of the wooden toothpick impacted into the colon wall. PMID- 30302159 TI - Lateral frontoethmoidal cell obstructing frontal sinus drainage pathway - report of six cases. AB - : The European Anatomical Position Paper on the Anatomical Terminology of the Internal Nose and Paranasal Sinuses distinguishes anterior, posterior, medial and lateral frontoethmoidal cells. The lateral cells have not been characterized yet. Other classifications (Lee and Kuhn, International Frontal Sinus Anatomy Classification) neglect them. The aim of this study is to describe lateral frontoethmoidal cells in rhinosinusitis patients. METHOD: Analysis of medical records and computed tomography (CT) examinations using multiplanar reconstruction with adjustable planes. The lateral cell extending between the frontal beak and the skull base pushing the frontal sinus drainage pathway medially/anteromedially was identified in 6 patients. These cells could not be classified as anterior, posterior or medial according to existing classifications. Four patients were operated on previously due to sinonasal symptoms. The lateral frontoethmoidal cell is an underestimated anatomical variation that may contribute to the persistence of inflammatory disease and can be easily overlooked preoperatively. PMID- 30302160 TI - Diagnostic and therapeutic recommendations for chronic pancreatitis. Recommendations of the Working Group of the Polish Society of Gastroenterology and the Polish Pancreas Club. AB - This article describes the latest diagnostic and therapeutic recommendations in chronic pancreatitis, developed by the Working Group of the Polish Society of Gastroenterology and the Polish Pancreas Club. The recommendations refer to the diagnosis of chronic pancreatitis, autoimmune pancreatitis, conservative management, treatment of pain, and exocrine and endocrine pancreatic insufficiency, treatment of chronic pancreatitis by endoscopic and surgical methods, and oncological surveillance of chronic pancreatitis. This paper refers to the Polish recommendations published in 2011, which have been updated and supplemented. All recommendations were voted by experts of the Polish Society of Gastroenterology and the Polish Pancreas Club, who evaluated them each time on a five-degree scale, where I meant full acceptance, II - acceptance with some reservation, III - acceptance with serious reservation, IV - rejection with some reservation and V - full rejection. The results of the voting, together with a brief commentary, have been included with each recommendation put to the vote. In addition, the expert group assessed the value of clinical studies on which the statements are based, on a scale where A means high (based on meta-analyses and randomised clinical trials), B means medium (based on clinical trials and observational studies), and C means low (based mainly on expert opinion). PMID- 30302161 TI - Morphology of Helicobacter pylori as a result of peptidoglycan and cytoskeleton rearrangements. AB - Helicobacter pylori is a Gram-negative, microaerophilic bacterium colonising the gastric mucosa. Normally, this bacterium has a spiral shape, which is crucial for proper colonisation of the stomach and cork-screwing penetration of dense mucin covering this organ. However, H. pylori may also form curved/straight rods, filamentous forms and coccoid forms. This morphological variability affects nutrient transport and respiration processes, as well as motility, the ability to form aggregates/biofilms, and resistance to adverse environmental factors. For this reason, a more accurate understanding of the molecular determinants that control the morphology of H. pylori seems to be crucial in increasing the effectiveness of antibacterial therapies directed against this microorganism. This article focuses on the molecular factors responsible for peptidoglycan and cytoskeleton rearrangements affecting H. pylori morphology and survivability. In addition, the existence of proteins associated with modifications of H. pylori morphology as potential targets in therapies reducing the virulence of this bacterium has been suggested. PMID- 30302162 TI - Carcinoid tumour of the oesophagus: a systematic review. AB - Introduction: Knowledge about oesophageal carcinoids is based primarily on case reports, and therefore information about them is incomplete. Aim: To collect information on oesophageal carcinoid tumours in a systematic review study. Material and methods: Databases including PubMed, Scopus, and Web of Science were searched for the characteristics of oesophageal carcinoid tumour. Studies included original articles, case series, or case reports, reporting at least one of the characteristics of benign carcinoid tumour or carcinoid tumour. Results: Out of 670 studies searched, after evaluation and excluding non-relevant studies, 14 studies were included and analysed in the systematic review. These studies included 19 patients with carcinoid tumour of whom 57.9% were males with a mean age of 55.5 years. Dysphagia and weight loss were the most prevalent symptoms and signs in the patients. Lower oesophagus was the most prevalent site of tumour. Conclusions: This meta-analysis showed that the mean age at diagnosis of oesophageal carcinoid was around 55 years, with 1.4 times greater prevalence among males, and located mainly in the distal oesophagus. The mean tumour size was 2.4 cm. The main symptoms and signs of this disease were dysphagia, weight loss, and reflux. The tumour behaviour was mainly non-aggressive except for cases associated with adenocarcinoma. PMID- 30302163 TI - Diagnosis and treatment of early gastric cancer: experience of one center. AB - Introduction: Gastric cancer is one of the most common malignant neoplasms in the world. Currently it constitutes the third cause of death among all malignancies. New endoscopic techniques have a potential to improve treatment results due to more frequent detection of early gastric cancer. Aim: To summarize our experience in diagnosis and treatment of early gastric cancer patients. Material and methods: We analyzed the results of endoscopic examination, histopathological findings and treatment methods in 16 patients who were diagnosed with early gastric cancer in the Endoscopy Unit of the Oncology Center in Bydgoszcz between 2014 and 2016. Results: Between 2014 and 2016 sixteen patients, 12 (75.0%) male and 4 (25.0%) female, were diagnosed with early gastric cancer. The average age of patients was 65.5 years. Surgery qualification concerned mainly G2 and G3 adenocarcinomas. In 12 (75.0%) patients total gastrectomy was performed, and 1 patient underwent wedge resection of the prepyloric part of the stomach. In 3 cases endoscopic submucosal dissection (ESD) was performed. Histopathological examination of both biopsy and postoperative material indicated 8 (50.0%) cases of intestinal-type adenocarcinoma, 7 (43.75%) cases of diffuse-type adenocarcinoma and 1 (6.25%) case of mixed-type adenocarcinoma. During the follow up after treatment, none of the patients was diagnosed with local or distant recurrence. Conclusions: Accurate examination technique allows for detection of early gastric cancer. Selected cases of early gastric cancer may be treated with advanced endoscopic techniques. PMID- 30302164 TI - Is narrow-band imaging a useful tool in screening colonoscopy performed by an experienced endoscopist? A prospective randomised study on 533 patients. AB - Introduction: The detection of adenomas is the basic goal for colorectal cancer screening programs; therefore, every possibility to improve the adenoma detection rate is valuable. Aim: To answer the question of whether narrow-band imaging (NBI) can enhance detection quality in screening for colonoscopy. Material and methods: A group of 533 patients (202 men: 331 women; average age: 56.1 years) included in a colorectal cancer screening program were randomised into two groups (NBI n = 266 and white light (WL) n = 267). Five hundred and twenty-seven patients were finally included in the assessment. Examinations were performed by three experienced colonoscopists. The NBI was used only at the withdrawal of the instrument. Results: Comparing WL and NBI colonoscopies, differences in the mean number of detected polyps per patient (1.36 +/-2.79 WL vs. 1.65 +/-2.11 NBI; p = 0.012), polyp detection rate (PDR) (48.5% WL vs. 57.2% NBI; p = 0.049), PDR for polyps <= 5 mm (44.7% WL vs. 54% NBI; p = 0.033), and PDR for left-sided polyps (43.3% WL vs. 52.7% NBI; p = 0.033) were observed. The difference in adenoma detection rate (ADR) as well as in adenomas/patient was not significant. Narrow band imaging enhanced significantly one of three operators' ADR (15.6% WL vs. 25.7% NBI; p = 0.038). Conclusions: It seems that NBI improves only detection of hyperplastic polyps, especially those that are diminutive and left-sided. However, after analysis of particular endoscopists, it can clearly be seen that some of them may benefit from NBI. PMID- 30302165 TI - Therapeutic efficacy of amoxicillin and rifaximin in patients with small intestinal bacterial overgrowth and Helicobacter pylori infection. AB - Introduction: Small intestinal bacterial overgrowth (SIBO) may coexist with Helicobacter pylori infection, which can be the cause of chronic gastrointestinal complaints. Aim: Evaluation of the therapeutic efficacy of amoxicillin and rifaximin in the treatment of these diseases. Material and methods: The lactulose hydrogen breath test (LHBT) and the urea breath test (13C-UBT) were performed in 116 patients. In 62 patients the coexistence of small intestinal bacterial overgrowth and H. pylori infection was observed. Then, in group I (n = 30) pantoprazole (2 * 40 mg), amoxicillin (2 * 1000 mg) and metronidazole (2 * 500 mg) and in group II (n = 32) pantoprazole and amoxicillin at the above doses and rifaximin (3 * 400 mg) were administered for 10 days. After 6 weeks, both breath tests were repeated and the degree of remission of symptoms was measured using a 10-point visual analog scale (VAS). Results: After the treatment the LHBT index decreased in group I from 61.2 +/-19.4 ppm to 22.0 +/-8.2 ppm (p < 0.001) and in group II from 59.6 +/-15.5 ppm to 15.2 +/-8.6 ppm (p < 0.001). Eradication of H. pylori (13C-UBT below 4.00/00) was achieved in 63.3% of patients in group I and 59.4% in group II (p > 0.05). The decrease of pain below 3.0 points in the VAS was obtained in 64.8% of patients in group I and in 56.2% in group II. Conclusions: Combination of amoxicillin and rifaximin may be effective in the treatment of patients with small intestinal bacterial overgrowth syndrome and concomitant H. pylori infection. PMID- 30302166 TI - The prognostic impact of neutrophil-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, and platelet-to-lymphocyte ratio in patients with advanced colorectal cancer treated with first-line chemotherapy. AB - Introduction: Colorectal cancer is the second most frequently diagnosed malignancy and one of the leading causes of cancer-related death in Poland. Many reports of different types of cancer have indicated that blood count parameters may serve as a source of prognostic or predictive information. Aim: To assess the association between these parameters and clinical outcome in patients with advanced colorectal cancer. Material and methods: We retrospectively analysed a database of 295 patients with advanced colorectal cancer treated with first-line palliative chemotherapy at our institution from January 2008 to December 2012. Blood-based parameters were measured before the first cycle of treatment. Results: The median progression-free survival (PFS) was 6.7 months, and the median overall survival was 17.6 months. A high neutrophil-to-lymphocyte ratio (NLR) and a high platelet-to-lymphocyte ratio (PLR) were associated with a shorter survival (hazard ratio (HR): 1.88, p < 0.0001 for the NLR and HR: 1.39, p = 0.0054 for the PLR), but for the PLR, we observed only a not significant trend toward a worse PFS (HR = 1.25, p = 0.07 for the PLR and HR = 1.55, p = 0.0004 for the NLR). A high lymphocyte-to-monocyte ratio (LMR) was associated with a better prognosis (HR = 0.58, p <= 0.0001) and a longer PFS (HR = 0.73, p = 0.011). Conclusions: The blood-based parameters are readily available, reliable, and low cost biomarkers, which can be easily incorporated into routine practice to predict the prognosis in patients with advanced colorectal cancer. PMID- 30302167 TI - Update on the effect of age on acute pancreatitis morbidity: a retrospective, single-center study. AB - Introduction: Acute pancreatitis (AP) is one of the urgent diseases of gastroenterology. Due to the growth of the elderly population, the frequency of the disease in the elderly population is also increasing. Aim: To evaluate the contributing factors of mortality in geriatric patients (age >= 65 years) and non geriatric (age < 65 years) patients. Material and methods: We retrospectively analyzed data of consecutive patients with AP, in the Adana Numune Education and Research Hospital between March 2013 and September 2015. Results: Of the 602 patients studied, 405 were female and 197 were male and their mean age was 55.2 +/-19.5 years. The most common etiological factors were biliary stone, hyperlipidemia and alcohol, respectively. Two hundred and four patients were in the geriatric group and 394 patients were in the non-geriatric group. 84.4% of patients had mild AP, and 15.6% of patients had moderate to severe AP according to the revised Atlanta classification. 91.7% of non-geriatric patients had mild AP while 70.7% of geriatric patients had mild AP (p < 0.001). 29.4% of geriatric patients had moderate-to-severe AP while 8.4% of non-geriatric patients had moderate-severe AP. Duration of hospital stay was 6.2 +/-3 days and 5.3 +/-2.3 days in geriatric and non-geriatric groups respectively (p < 0.001). Mortality was higher in the geriatric group than the non-geriatric group (9.6% vs. 0.5%, respectively) (p < 0.001). Conclusions: Acute pancreatitis in the geriatric population shows a more severe course than the non-geriatric population. Geriatric patients have longer duration of hospital stay and higher mortality than non-geriatric patients. PMID- 30302168 TI - Comparison of the effects and side-effects of sedation with propofol versus midazolam plus pethidine in patients undergoing endoscopy in Imam Khomeini Hospital, Ahvaz. AB - Introduction: Gastrointestinal endoscopy is an invasive and diagnostic procedure that causes the patients considerable pain, discomfort, and anxiety. Therefore, various types of sedation and analgesia techniques have been used during the procedure. Aim: To compare the effects and side-effects of sedation with propofol versus midazolam plus pethidine in patients undergoing endoscopy. Material and methods: This is a randomised controlled double-blind clinical trial study conducted on 272 patients undergoing diagnostic and treatment endoscopy and colonoscopy in Imam Khomeini Hospital in Ahvaz between 2017 and 2018. The patients were randomly assigned to two groups. Patients in the first group (n = 136) received propofol with midazolam and ketamine, and the second group (n = 136) received pethidine and midazolam. Study outcome measures included the recovery time, patient satisfaction, quality of sedation, and adverse events. Results: The occurrence of complications was higher in the propofol group (25% vs. 0%; p = 0.0001). No serious adverse events were observed in the study groups. Overall patient satisfaction and quality of sedation assessment scores in the propofol group were significantly better than those seen in the pethidine midazolam group (p = 0.012 and p = 0.001, respectively). Recovery time was statistically shorter in the propofol-midazolam group (6.05 +/-1.62 min) compared to the pethidine-midazolam group (6.72 +/-2.21 min) (p = 0.006). Conclusions: Propofol-midazolam can provide better sedation, patient satisfaction, and recovery than pethidine-midazolam during endoscopy. Therefore, it can be recommended in patients scheduled for diagnostic and treatment endoscopy. PMID- 30302169 TI - Endoscopic findings in patients with familial Mediterranean fever and dyspeptic symptoms. AB - Aim: The aim of the study was to evaluate the clinical, endoscopic, histopathological, laboratory, and imaging findings of patients with familial Mediterranean fever (FMF) presenting with dyspeptic symptoms. Material and methods: Endoscopy was performed in 28 patients with FMF undergoing colchicine therapy, who presented to our hospital between 2012 and 2014 with abdominal pain, diarrhoea, and dyspeptic complaints. Upper gastrointestinal system endoscopy was performed in all patients; 16 of these underwent colonoscopy. Demographic characteristics, clinical and laboratory data, genetic analysis, imaging data, and endoscopy and colonoscopy findings were evaluated in all patients. Results: Histopathological analysis of biopsy specimens revealed gastrointestinal pathology in 21 (75%) patients. Upper endoscopy analysis revealed that 14 (50%) patients had antral gastritis (8 Helicobacter pylori (-) antral gastritis and 6 H. pylori (+) chronic active gastritis) and 2 (7%) cases had giardiasis. Four antral gastritis cases had concomitant esophagitis, and 2 patients had widespread ulcers in the terminal ileum. The rest had a normal colonic appearance; however, three patients with normal colonoscopic findings were found to have chronic active colitis on histopathological examination. Conclusions: In this study, most patients with FMF presenting with dyspeptic complaints had gastrointestinal pathology. Furthermore, there was higher inflammatory bowel disease incidence in these patients. PMID- 30302170 TI - Safety analysis of endoscopic haemostasis using a high-frequency live tissue electric welding device - EKVZ300 PATONMED. AB - Introduction: The method of a bipolar high-frequency welding (HFEW) of soft living tissues of animals and humans has been used in various areas of surgery. However, it has not been utilized in endoscopic gastrointestinal procedures yet. HFEW has strong potential to be used in gastrointestinal endoscopic procedures due to the competitive cost of generator devices and due to its proven ability to coagulate vessels of wide diameter as compared to standard electrocautery devices. Aim: To investigate the effectiveness of the endoscopic haemostasis using HFEW generator device - 300 PATONMED - in a porcine model of arterial gastrointestinal bleeding. Material and methods: A porcine model of arterial gastrointestinal bleeding was created. A 300 PATONMED set to the "welding" regime and a flexible 7 Fr bipolar coagulation probe with two electrodes on the tip fashioned spirally attached to convey energy were tested. Once bleeding from the artery had been initiated, the bipolar probe was applied to coagulate the bleeding site. Animals were observed for clinical evidence of recurrent bleeding and subsequently were euthanised for histological examination. Results: A total of 10 experiments were successfully completed. An optimal haemostatic effect was achieved with durations of cautery of five to eight seconds in all animals. Continuous observation after haemostasis revealed no evidence of re-bleeding. No systemic side-effects of the technique were observed. Histological examination has shown that the peripheral thermal injury area that surrounded the coagulation zone did not spread beyond the mucosal layer in depth and 2 mm in width. Conclusions: This animal study provided evidence for the safety of an HFEW in the treatment of gastrointestinal bleeding. The advantages of this technology are smokeless operative area, no tissue overheating, minimal necrosis and damage to surrounding gastric tissue, and the fact that the area of HFEW is confined to the area of the electrodes.

PMID- 30302171 TI - Single transluminal gateway transcystic multiple drainage for extensive walled off pancreatic necrosis - a single-centre experience. AB - Introduction: In last three decades we have observed development in minimally invasive techniques in the treatment of walled-off pancreatic necrosis (WOPN). Endoscopic treatment of the consequences of acute necrotising pancreatitis is a accepted and common minimally invasive method. Aim: Evaluation of the efficiency and safety of the innovative endoscopic treatment method (single transluminal gateway transcystic multiple drainage - SGTMD) in patients with extensive walled off pancreatic necrosis. Material and methods: The retrospective analysis of 114 consecutive patients with symptomatic WOPN, who were treated endoscopically in our medical centre between 2011 and 2016. Results: Single transluminal gateway transcystic multiple drainage was performed in 21/114 (18.42%) patients. Endoscopic necrosectomy under fluoroscopic guidance was performed in 12/21 (57.14%) patients. Complications of treatment appeared in 7/21 (33.33%) patients. The most common of complication was upper gastrointestinal bleeding treated conservatively with packed red blood cells transfusions. There were no deaths. Therapeutic success was reached in 20/21 (95.24%) patients. No patient required surgery. The medium time of follow-up was 22 months (16-47). During the observation the recurrence of pancreatic fluid collection was noticed in 1/21 (4.76%) patients. Long-term success of endoscopic treatment was achieved in 19/21 (90.47%) patients. Conclusions: Single transluminal gateway transcystic multiple drainage is an effective method of endoscopic treatment for extensive walled-off pancreatic necrosis with an acceptable amount of complications. However, the method of interventional treatment of pancreatic necrosis should depend not only on the location of necrosis, but also on the experience of the medical centre.

PMID- 30302177 TI - A comparison of medication adherence between subsidized and self-paying patients in Malaysia. AB - Background: Limited efforts have been made to evaluate medication adherence among subsidized and self-paying patients. Objective: To investigate medication adherence among patients with and without medication subsidies and to identify factors that may influence patients' adherence to medication. Setting: Government healthcare institutions in Kuala Lumpur, Selangor, and Negeri Sembilan and private healthcare institutions in Selangor and Negeri Sembilan, Malaysia. Methods: This cross-sectional study sampled patients with and without medication subsidies (self-paying patients). Only one of the patient's medications was re packed into Medication Event Monitoring Systems (MEMS) bottles, which were returned after four weeks. Adherence was defined as the dose regimen being executed as prescribed on 80% or more of the days. The factors that may influence patients' adherence were modelled using binary logistic regression. Main outcome measure: Percentage of medication adherence. Results: A total of 97 patients, 50 subsidized and 47 self-paying, were included in the study. Medication adherence was observed in 50% of the subsidized patients and 63.8% of the self-paying patients (chi2=1.887, df=1, p=0.219). None of the evaluated variables had a significant influence on patients' medication adherence, with the exception of attending drug counselling. Patients who attended drug counselling were found to be 3.3 times more likely to adhere to medication than those who did not (adjusted odds ratio of 3.29, 95% CI was 1.42 to 7.62, p = 0.006). Conclusion: There is no significant difference in terms of medication adherence between subsidized and self-paying patients. Future studies may wish to consider evaluating modifiable risk factors in the examination of non-adherence among subsidized and self-paying patients in Malaysia. PMID- 30302178 TI - Achieving triple treatment goals in multi-ethnic Asian patients with type 2 diabetes mellitus in primary care. AB - Introduction: Achieving optimal glycated hemoglobin (HbA1c), blood pressure (BP), and LDL-Cholesterol (LDL-C) in patients mitigates macro- and micro-vascular complications, which is the key treatment goal in managing type 2 diabetes mellitus (T2DM). This study aimed to determine the proportion of patients in an urban community with T2DM and the above modifiable conditions attaining triple vascular treatment goals based on current practice guidelines. Methods: A questionnaire was distributed to adult Asian patients with dyslipidemia at two primary care clinics (polyclinics) in northeastern Singapore. The demographic and clinical data for this sub-population with both T2DM and dyslipidemia were collated with laboratory and treatment information retrieved from their electronic health records. The combined data was then analyzed to determine the proportion of patients who attained triple treatment goals, and logistic regression analysis was used to identify factors associated with this outcome. Results: 665 eligible patients [60.5% female, 30.5% Chinese, 35% Malays, and 34.4% Indians] with a mean age of 60.6 years were recruited. Of these patients, 71% achieved LDL-C <=2.6 mmol/L, 70.4% had BP 90% can be achieved with rituximab-based chemoimmunotherapy in advanced stage patients, the complete remission rates are substantially lower and patients inevitably relapse. The inability to achieve a complete remission and an early progression of disease have recently been determined to be indicative of poorer long-term outcomes. A greater understanding of the pathogenesis of follicular lymphoma has enabled the development of targeted therapies, which may improve standard treatment approaches. Examples include lenalidomide and obinutuzumab, which are currently in front-line Phase III investigation. Other therapies of interest include small molecule inhibitors, immune checkpoint inhibitors and chimeric antigen receptor T cells.

AB - Although the treatment modalities for acute myeloid leukemia (AML) have not changed much over the past 40 years, distinct progress has been made in deciphering the basic biology underlying the pathogenesis of this group of hematological disorders. Studies show that AML development is a multicause, multistep and multipathway process. Accordingly, AMLs constitute a heterogeneous group of diseases. The thorough understanding of the molecular basis of AML is paving the way for better therapeutic approaches. Multiple novel drugs are being introduced and new, more efficient and less toxic formulations of conventional therapeutics are becoming available. Here, we review the recent advances in the comprehension of the molecular processes that lead to the onset of AML and its translation into clinical practice.

In systemic lymphomas, there are situations where non-Hodgkin lymphomas have resolved spontaneously. We now report the case of a nonimmunocompromised patient with primary CNS lymphoma who underwent a spontaneous remission with a durable response. This case suggests that not all patients with primary CNS lymphomas require aggressive treatment with chemotherapy and radiation therapy. PMID- 30302229 TI - Interview with Dr Philip McCarthy.

PMID- 30302228 TI - Defibrotide for the treatment of hepatic veno-occlusive disease/sinusoidal obstruction syndrome with multiorgan failure. AB - Hepatic veno-occlusive disease, also called sinusoidal obstruction syndrome (VOD/SOS), is a potentially life-threatening and unpredictable complication of hematopoietic stem cell transplantation (HSCT). Characterized by a prothrombotic hypofibrinolytic state, VOD/SOS typically presents with hyperbilirubinemia, ascites, weight gain and painful hepatomegaly; VOD/SOS with multiorgan failure may be associated with >80% mortality. Treatment has been mainly supportive. However, defibrotide is now approved in the USA for treatment of hepatic VOD/SOS with renal or pulmonary dysfunction following HSCT and in the European Union for treatment of severe hepatic VOD/SOS post-HSCT. In vitro evidence suggests defibrotide may restore thrombotic-fibrinolytic balance at the endothelial level and protect endothelial cells. Defibrotide has demonstrated significant reduction in VOD/SOS-related mortality and resolved VOD/SOS-related symptoms, with a manageable safety profile. PMID- 30302231 TI - Untreated chronic lymphocytic leukemia in Lebanese patients: an observational study using standard karyotyping and FISH. AB - Aim: We aimed to understand the biology of chronic lymphocytic leukemia (CLL) patients in Lebanon. Materials & methods: We applied conventional cytogenetic and FISH studies on Lebanese patients diagnosed with CLL and undergoing a watch and wait approach. Results: Our study disclosed 53.6% of patients with aberrant karyotypes among which 26.7% were complex karyotypes. Genetic aberrations included del(13q14) 46.4%, 14q32 translocation in 25%, trisomy 12 in 14.3%, del(17p13) and del(11q22) in 7.1% each. The deletion of 6q21/6q23 was not found in any of our patients. Conclusion: The higher prevalence of del(13q14) as a sole abnormality could be the primary event in inducing CLL. The del(17p13) and del(11q22) followed as potential drivers for progression in CLL patients with a watch and wait approach. PMID- 30302232 TI - Long-term outcomes of rituximab, temozolomide and high-dose methotrexate without consolidation therapy for lymphoma involving the CNS. AB - Aim: To describe the long-term outcomes of patients with lymphoma in the CNS treated with rituximab, temozolomide and high-dose methotrexate without consolidation therapy. Patients & methods: A retrospective cohort study of 46 consecutive patients with primary CNS lymphoma (PCNSL, 27 patients) or secondary CNS involvement of diffuse large B-cell lymphoma (DLBCL, 19 patients) who were treated with rituximab on day 1 in combination with high-dose methotrexate (days 1 and 15) and temozolomide (days 1-5) in 28-day cycles without further consolidation. Results: Median follow-up was 21.2 months. Patients received a median of five cycles (range 1-15). Median overall survival (OS) was 26 months and median progression-free survival was 8.6 months. At 3 years, 37% of patients were alive and without evidence of disease. The patients with PCNSL had a significantly higher response rates (ORR 81 vs 47%; p = 0.015) and longer median OS (55.3 vs 4.8 months; p < 0.01) than those with secondary CNS DLBCL. Toxicities were mild and manageable. Conclusion: The rituximab, temozolomide and methotrexate regimen is an effective therapy for patients with PCNSL without the toxicities typically associated with consolidation therapy. PMID- 30302233 TI - Radioimmunotherapy-based conditioning regimen prior to autologous stem cell transplantation in non-Hodgkin lymphoma. AB - Non-Hodgkin lymphoma (NHL) is the most common hematologic malignancy and the sixth cause of death from cancer in the USA. Autologous stem cell transplantation (ASCT) is a potentially curative therapeutic option for many NHL patients. Choosing the most effective conditioning regimen prior to ASCT can lead to longer survival in these patients, and, as in many cases of high risk NHL, the only potentially curative option is stem cell transplantation. Radioimmunotherapy (RIT) is based on using radiolabeled monoclonal antibodies against tumoral antigens. Since lymphoma cells are sensitive to radiation, RIT has become a potential approach in treating NHL. In this review, we have discussed the efficacy and safety of RIT as an alternative conditioning regimen prior to ASCT. PMID- 30302234 TI - Management of older adults with acute lymphoblastic leukemia: challenges & current approaches. AB - The management of acute lymphoblastic leukemia (ALL) in older patients is challenging. Older patients often have multiple comorbidities and poor performance status, and disease factors associated with poor prognosis are more common in this age group. Patient and disease-related factors should be taken into account to determine whether intensive therapy is appropriate. The use of comorbidity indices and comprehensive geriatric assessment tools can be valuable in this setting. Fit patients should be considered for aggressive therapies including allogeneic hematopoietic stem cell transplantation, whereas low intensity options may be more suitable for the frail. The Philadelphia (Ph) chromosome is present in up to half of the cases of ALL in older patients. The incorporation of TK inhibitors into the treatment plans of older patients with Ph positive ALL has improved the outcomes significantly. For less fit patients with Ph-positive ALL, the use of TK inhibitors with reduced-intensity chemotherapy or steroids alone results in high rates of remission, but, without further consolidation, relapses are inevitable. Many novel targeted and immunotherapeutic agents are being developed, offering more effective and tolerable treatment options. PMID- 30302235 TI - Isolated hypoglossal nerve palsy as a presenting symptom of metastatic peripheral T-cell lymphoma - not otherwise specified (PTCL-NOS): a unique case & a review of the literature. AB - Extensive and significant technological advancements have enhanced the sensitivity and accuracy of the pathologic classification, diagnosis, and therapeutics of lymphoma. These advances have prompted a more comprehensive understanding of neoplastic behavior and have led to improvements in both treatment and prognosis. This paper presents a comprehensive review of lymphoma and features a case report of a unique presentation of peripheral T-cell lymphoma - not otherwise specified that presented with isolated hypoglossal nerve dysfunction. PMID- 30302236 TI - Chart review across EU5 in MM post-ASCT patients. AB - Aim: To understand the current treatment patterns, clinical outcomes and healthcare resource utilization-associated costs for multiple myeloma patients, post autologous stem cell transplant (ASCT) across Europe. Patients & methods: Medical records were used to abstract data for 337 multiple myeloma patients who had received ASCT. Results: Following ASCT, 7% received maintenance therapy prior to progression. Lenalidomide was the most frequently prescribed maintenance, second- and third-line therapy. Monthly resource use was considerably lower in patients who received maintenance therapy (?638.14 vs ?1001.74). Median time to progression was longer for patients who had received maintenance therapy. Conclusion: The study highlights the diversity in current treatment patterns post ASCT. Results suggest patients who receive maintenance therapy have a prolonged remission period, and as a result their associated healthcare resource utilization is spread across the treatment pathway.

PMID- 30302238 TI - Spinal epidural lipomatosis presenting to a U.S. Veterans Affairs pain and rehabilitation department: a report of two cases. AB - Background: Spinal epidural lipomatosis is an uncommon source of neurogenic claudication. We present two cases of spinal epidural lipomatosis as it relates to diagnosis, management, and a possible association with common medical intervention. Case presentation: Case 1: 63-year old male patient presented with neurogenic claudication symptoms, but without evidence of bony central canal stenosis on lumbar computed tomography. He entered a trial of spinal manipulation with transient beneficial gains after seven appointments, but no durable change in neurogenic claudication. An MRI was recommended at this point which revealed grade III spinal epidural lipomatosis at the L5/S1 level.Case 2: 51-year old male patient presented to a pain management physician with radicular symptoms for a series of lumbar epidural steroid injections. He completed a series of three lumbar epidural steroid injections with only short-term benefit. A repeat MRI demonstrated the presence of grade I (borderline grade II) spinal epidural lipomatosis. Conclusions: The first case illustrates a limitation of ruling out central canal stenosis with computed tomography for patients unable to undergo an MRI. The second case demonstrates a possible association between steroid injections and spinal epidural lipomatosis. An association of this kind has not been established; further research is needed to determine the significance.

AB - A rapid, precise method for identifying waterborne pathogens is critically needed for effective disinfection and better treatment. However, conventional methods, such as culture-based counting, generally suffer from slow detection times and low sensitivities. Here, we developed a rapid detection method for tracing waterborne pathogens by an innovative optofluidic platform, a plasmonic bacteria on a nanoporous mirror, that allows effective hydrodynamic cell trapping, enrichment of pathogens, and optical signal amplifications. We designed and simulated the integrated optofluidic platform to maximize the enrichment of the bacteria and to align bacteria on the nanopores and plasmonic mirror via hydrodynamic cell trapping. Gold nanoparticles are self-assembled to form antenna arrays on the surface of bacteria, such as Escherichia coli and Pseudomonas aeruginosa, by replacing citrate with hydroxylamine hydrochloride in order to amplify the signal of the plasmonic optical array. Owing to the synergistic contributions of focused light via the nanopore geometry, self-assembled nanoplasmonic optical antennas on the surface of bacteria, and plasmonic mirror, we obtain a sensitivity of detecting E. coli as low as 102 cells/ml via surface enhanced Raman spectroscopy. We believe that our label-free strategy via an integrated optofluidic platform will pave the way for the rapid, precise identification of various pathogens. PMID- 30302240 TI - Multimode optical fiber transmission with a deep learning network. AB - Multimode fibers (MMFs) are an example of a highly scattering medium, which scramble the coherent light propagating within them to produce seemingly random patterns. Thus, for applications such as imaging and image projection through an MMF, careful measurements of the relationship between the inputs and outputs of the fiber are required. We show, as a proof of concept, that a deep neural network can learn the input-output relationship in a 0.75 m long MMF. Specifically, we demonstrate that a deep convolutional neural network (CNN) can learn the nonlinear relationships between the amplitude of the speckle pattern (phase information lost) obtained at the output of the fiber and the phase or the amplitude at the input of the fiber. Effectively, the network performs a nonlinear inversion task. We obtained image fidelities (correlations) as high as ~98% for reconstruction and ~94% for image projection in the MMF compared with the image recovered using the full knowledge of the system transmission characterized with the complex measured matrix. We further show that the network can be trained for transfer learning, i.e., it can transmit images through the MMF, which belongs to another class not used for training/testing. PMID- 30302241 TI - Attenuation artifacts in light sheet fluorescence microscopy corrected by OPTiSPIM. AB - Light sheet fluorescence microscopy (LSFM) is rapidly becoming an essential technology for mesoscopic imaging of samples such as embryos and adult mouse organs. However, LSFM can suffer from optical artifacts for which there is no intrinsic solution. The attenuation of light due to absorbing material causes "shadow" artifacts along both the illumination and detection paths. Several approaches have been introduced to reduce this problem, including scanning illumination and multi-view imaging. However, neither of these approaches completely eliminates the problem. If the distribution of the absorbing material is complex, shadows cannot be avoided. We introduce a new approach that relies on multi-modal integration of two very different mesoscopic techniques. Unlike LSFM, optical projection tomography (OPT) can operate in transmission mode to create a voxel map of the 3D distribution of the sample's optical attenuation. Here, we demonstrate a hybrid instrument (OPTiSPIM) that can quantify this attenuation and use the information to correct the shadow artifacts of LSFM. PMID- 30302242 TI - GOBO projection for 3D measurements at highest frame rates: a performance analysis. AB - Aperiodic sinusoidal patterns that are cast by a GOBO (GOes Before Optics) projector are a powerful tool for optically measuring the surface topography of moving or deforming objects with very high speed and accuracy. We optimised the first experimental setup that we were able to measure inflating car airbags at frame rates of more than 50 kHz while achieving a 3D point standard deviation of ~500 um. Here, we theoretically investigate the method of GOBO projection of aperiodic sinusoidal fringes. In a simulation-based performance analysis, we examine the parameters that influence the accuracy of the measurement result and identify an optimal pattern design that yields the highest measurement accuracy. We compare the results with those that were obtained via GOBO projection of phase shifted sinusoidal fringes. Finally, we experimentally verify the theoretical findings. We show that the proposed technique has several advantages over conventional fringe projection techniques, as the easy-to-build and cost effective GOBO projector can provide a high radiant flux, allows high frame rates, and can be used over a wide spectral range. PMID- 30302243 TI - Recurrent diabetic myonecrosis -an under-diagnosed cause of acute painful swollen limb in long standing diabetics. AB - Diabetic myonecrosis (DMN) is an under-diagnosed complication of long-standing poorly controlled diabetes mellitus. It presents as abrupt pain and swelling of the extremity, mostly lower limbs. Diagnosis is often delayed as it mimics a number of clinical entities such as deep vein thrombosis (DVT), cellulitis, necrotizing fasciitis and malignancy. Failure to properly identify this condition can result in increased morbidity through exposure to unnecessary tests and biopsy. A 56-year-old male with a history of complicated type 2 diabetes mellitus, hypertension presented to emergency with gradually worsening left calf pain for last 2 weeks. A lower-extremity venous Doppler was negative for DVT. Magnetic resonance imaging (MRI) was suggestive of muscle edema likely of inflammatory etiology. Muscle biopsy revealed myonecrosis with ischemic myopathy and was negative for vasculitis or inflammatory myopathy. He was managed conservatively and his symptoms resolved in 4 weeks. After 6 months he had recurrence in right thigh which was managed conservatively too. Given these findings, a diagnosis of recurrent diabetic myonecrosis was made. Myonecrosis is a less known microvascular complications of diabetes and should always be keep in mind when evaluating a diabetic patient with muscle pain. Diagnosis can be made on MRI in appropriate clinical settings. The clinical course is usually self limiting and patients respond well to supportive medical therapy that involves bed rest, strict glycemic control along with analgesic. PMID- 30302244 TI - Laparoscopic cholecystectomy using the PINPOINT(r) Endoscopic Fluorescence Imaging System with intraoperative fluorescent imaging for acute cholecystitis: A case report. AB - We report on a laparoscopic cholecystectomy (LC) for acute cholecystitis (AC) using the bright field/full-color fluorescence laparoscope system PINPOINT(r) (Novadaq, Mississauga, ON, Canada). The patient was an 85-year-old man who was diagnosed with moderate AC. Indocyanine green (ICG) was administered just before surgery, and we used only PINPOINT(r) to perform the LC. The advantage of this procedure is that it can be performed while viewing ICG fluorescence in the cystic duct. Since the gallbladder is imaged with this technique, it is also advantageous from the perspective of deciding at which layer to detach the gallbladder from the liver. The operative time was 81 minutes, and blood loss was 5 ml. There were no perioperative complications, and the patient was discharged on post-operative day 6. PMID- 30302245 TI - Factors during training which predict future use of minimally invasive thoracic surgery. AB - Background: While minimally invasive thoracic surgery (MIS) has increased nationwide over the years, most patients undergoing lung and esophageal resections still undergo an open approach. We performed a national survey to analyze factors associated with a propensity to perform MIS after completing a cardiothoracic training program. Materials and methods: Cardiothoracic surgery trainees in 2 or 3-year programs from 2010 to 2016 were sent an online survey regarding the numbers and types of cases performed during training and current practice patterns as attending surgeons. Comfort level with MIS was also assessed. Responses were recorded and analyzed using SPSS. Results: One hundred thirty-six trainees responded, with a mean of 121 lobectomies (30-250) and 40 esophagectomies (8-110) performed during training. Mean minimally invasive lobectomy and esophagectomy rates during training were 53% and 30% respectively. A greater ratio of MIS procedures performed during training correlated with a higher rate performed as an attending (lobectomies, p = 0.04; esophagectomies, p = 0.01) and a greater comfort level with performing these procedures (lobectomies, p = 0.01 and esophagectomies, p < 0.01). Conclusions: Based on these results, performing a greater ratio of minimally invasive lobectomies and esophagectomies during fellowship training increases the likelihood of performing them as an attending. PMID- 30302246 TI - Prevalence of Helicobacter pylori in asymptomatic patients at surgical outpatient department: Harare hospitals. AB - Background: Helicobacter pylori infection is present in more than 50% of the world's population. The estimated life time risk of peptic ulcer disease is 20 percent and of gastric cancer is 1-2 percent. Materials and methods: A cross sectional study was done at two Central hospitals in Harare, Zimbabwe, with the objective being to estimate the prevalence of Helicobacter pylori infection in asymptomatic individuals. Other objectives were to determine the association of the Helicobacter pylori infection with potential risk factors.Four hundred and fifty patients visiting the outpatient surgical clinics for other complaints other than upper gastrointestinal symptoms were recruited in the study. Drops of whole blood were obtained by fingertip puncture from each patient. The Onsite H. pylori Combo Rapid Test was used to confirm the presence or absence of antibodies against Helicobacter pylori. A questionnaire was used to record the sociodemographics of the participants. Results: Three hundred patients, 186 males (62%) and 114 females (38%) participated. The prevalence of Helicobacter pylori infection was 67.7 percent (203/300). The prevalence of H pylori infection was significantly correlated with increasing age (p = 0.012), sharing of a bed with siblings during childhood (p = 0.013) and the mode of sanitation methods (p = 0.023). There was no association found between H pylori infection and other risk factors such as; gender, level of education, employment status or number of rooms in a house. Conclusion: H. pylori infection prevalence was significantly associated with increasing age, sharing of a bed with siblings during childhood and the mode of sanitation used. Clinicians and the public have to be aware of the important role of H pylori in upper gastrointestinal disease. Use of better sanitation methods, appropriate hygiene, avoidance of over-crowding amongst other measures should be encouraged as a means to reduce the acquisition and transmission of H pylori. PMID- 30302248 TI - Assessing the feasibility of parent participation in a commercial weight loss program to improve child body mass index and weight-related health behaviors. AB - Objectives: Little is known about how children's health might be affected by parents' participation in commercial weight loss programs. Given that more than 3.2 million people subscribe to just one commercial weight loss program, Weight Watchers, any secondary effects on children's weight-related health behaviors (e.g. dietary behaviors, physical activity, and sedentary time) and body mass index from parent participation in commercial weight loss programs may have significant public health implications. This study examined the feasibility of conducting a study to assess such effects. Methods for recruitment and retention, and perceived acceptability and satisfaction among participants in small-scale preliminary study, were evaluated. Changes in body mass index and health behaviors among the parent-child dyads were also measured to test whether a larger-scale study would be warranted. Methods: This was an 8-week, pre-post observational feasibility study involving 20 parent-child dyads where both members had overweight or obesity. Physical and behavioral data were collected at baseline and 8 weeks from both members of the dyads. Parenting data were collected at the same time periods through parents' self-report. Bivariate correlation was used to quantify the associations in changes for dyad members. Results: Feasibility goals for retention and perceived acceptability/satisfaction among participants were met. We reached approximately 80% of our enrollment goal. Parents showed a significant decrease in body mass index of 0.53 points (p < 0.05), while children showed a significant increase in raw body mass index (0.42, p < 0.05) and body mass index percentile (0.59, p < 0.05). However, correlation between changes in parent body mass index and changes in children body mass index percentile was positively correlated (r = 0.24, p = 0.31). A decrease in parent intake of total fat was associated with a decrease in the intake of fat in their children (r = 0.47, p < 0.05). Conclusion: Our findings support the viability of a larger-scale follow-up to assess the potential of using parent-only commercial weight loss program as a mechanism for improving health behaviors and body mass index in children with overweight or obesity. PMID- 30302249 TI - Quality assessment of controlled clinical trials published in Orthopaedics and Traumatology journals in Spanish: An observational study through handsearching and evidence mapping. AB - Few Orthopaedics and Traumatology journals from Latin America and Spain are indexed in major databases; controlled clinical trials published in these journals cannot be exhaustively retrieved using electronic literature searches. We aimed to identify, describe and assess the quality of controlled clinical trials published in Orthopaedics and Traumatology journals from Latin America and Spain through handsearching and evidence mapping methods. We identified controlled clinical trials published in eligible Orthopaedics/Traumatology journals in Spanish until July 2017 by handsearching. Data were extracted for controlled clinical trials main characteristics and the Cochrane risk of bias tool was used to assess the controlled clinical trials methodological quality. In addition, we mapped the main findings of these trials. As a result, we assessed 5631 references in 29 eligible journals of which 57 were controlled clinical trials (1.0%). Controlled clinical trials were published between 1995 and 2017 at a rate of 2.5 per year. Journals from Spain and Mexico published around 63% of the controlled clinical trials identified. The median sample size of patients enrolled was 60 (range = 30-300 participants). About conditions assessed, 38.5% of controlled clinical trials assessed issues related to knee conditions, 15.7% about hip and 10.5% about trauma or spine. The risk of bias domains most affected was selective reporting bias and random sequence generation. In addition, only two and seven trials had low risk of bias in all items related to participant/personnel and outcome assessment blindings, respectively. More than 40% of studies did not report differences on benefits/harms between the interventions assessed. As a conclusion, the number of controlled clinical trials published in Orthopaedics/Traumatology journals from Latin America and Spain is low. These controlled clinical trials had important methodological shortcomings and were judged as unclear or high risk of bias. These trials are now available in CENTRAL for their potential inclusion in systematic reviews and other documents of synthesis. PMID- 30302250 TI - Photodistributed sarcoidosis: a case report and approach to management. AB - Sarcoidosis is an idiopathic disease, characterized by non-caseating granulomas in multiple organs/tissues. Cutaneous involvement occurs in approximately one quarter of patients with a wide variety of presenting morphologies. This case report describes a case of photodistributed sarcoidosis, a rare cutaneous variant, with systemic involvement. A 42-year-old man presented with a history of a pruritic, rash with photoexacerbated annular plaques along with arthralgias and bone pain. Compared to previous reports of photodistributed sarcoidosis, our case presented with annular plaques rather than papules, and there was no prior exposure to ionizing radiation. He was treated successfully with prednisone and hydroxychloroquine. It is important to include sarcoidosis in the differential of photodistributed dermatoses. PMID- 30302247 TI - Management of severe acute exacerbations of COPD: an updated narrative review. AB - Background: Patients with chronic obstructive pulmonary disease (COPD) may experience an acute worsening of respiratory symptoms that results in additional therapy; this event is defined as a COPD exacerbation (AECOPD). Hospitalization for AECOPD is accompanied by a rapid decline in health status with a high risk of mortality or other negative outcomes such as need for endotracheal intubation or intensive care unit (ICU) admission. Treatments for AECOPD aim to minimize the negative impact of the current exacerbation and to prevent subsequent events, such as relapse or readmission to hospital. Main body: In this narrative review, we update the scientific evidence about the in-hospital pharmacological and non pharmacological treatments used in the management of a severe AECOPD. We review inhaled bronchodilators, steroids, and antibiotics for the pharmacological approach, and oxygen, high flow nasal cannulae (HFNC) oxygen therapy, non invasive mechanical ventilation (NIMV) and pulmonary rehabilitation (PR) as non pharmacological treatments. We also review some studies of non-conventional drugs that have been proposed for severe AECOPD. Conclusion: Several treatments exist for severe AECOPD patients requiring hospitalization. Some treatments such as steroids and NIMV (in patients admitted with a hypercapnic acute respiratory failure and respiratory acidosis) are supported by strong evidence of their efficacy. HFNC oxygen therapy needs further prospective studies. Although antibiotics are preferred in ICU patients, there is a lack of evidence regarding the preferred drugs and optimal duration of treatment for non-ICU patients. Early rehabilitation, if associated with standard treatment of patients, is recommended due to its feasibility and safety. There are currently few promising new drugs or new applications of existing drugs. PMID- 30302251 TI - Variable response of post-Mohs surgery telangiectasias to KTP laser: A case report. AB - A common but under-recognized complication of Mohs micrographic surgery is the development of surgical site telangiectasias after repair. Treatment with pulsed dye laser has shown good results in treating periscar telangiectasias, while treatment with KTP laser has never been studied for this complication. We report the findings in six patients with persistent telangiectasias post-Mohs micrographic surgery and their response to treatment with KTP laser. After one treatment with KTP laser, the severity of telangiectasias, scar erythema, and patient and physician-rated improvement were recorded. Response to KTP laser was variable. However, this case series suggests that KTP laser may have the potential to improve the appearance of periscar telangiectasia after Mohs micrographic surgery. PMID- 30302252 TI - Pulmonary hernia: Case report and review of the literature. AB - Pulmonary hernia (PH) is an uncommon condition. We report a case of PH secondary to thoracic surgical intervention. In addition to the rarity, the peculiarity of the case is given by the clinical course as it is characterized by a clinical latency before the onset. The patient showed risk factors such as obesity and poliomyelitis infection sequelae. We also reviewed the literature about this topic. PMID- 30302253 TI - Recurrent respiratory papillomatosis: the role of cidofovir. AB - Recurrent respiratory papillomatosis (RRP) is a rare condition that affects the respiratory system. It is caused by human papilloma virus (HPV) infection. Usually infection and papilloma growth is limited to 6-12 months duration; however, some patients have persistent disease, resulting in long-term symptoms and the need for recurrent intervention. Predominant symptoms include shortness of breath, reduced exercise tolerance and voice deterioration during flares. Current gold-standard management is through resection via microdebrider, CO2 laser, cryotherapy, electrocoagulation, Nd: YAG laser or pulse-dye laser. However, despite these therapies, approximately 20% of patients require adjuvant therapy. We discuss the use of intralesional cidofovir in the management of tracheal papillomatosis. Cidofovir's mechanism of action involves incorporating into the virus DNA chain and therefore, inhibiting the viral DNA polymerization process and hence replication. PMID- 30302254 TI - Monitoring of sedation depth in intensive care unit by therapeutic drug monitoring? A prospective observation study of medical intensive care patients. AB - Background: Analgosedation is a cornerstone therapy for mechanically ventilated patients in intensive care units (ICU). To avoid inadequate sedation and its complications, monitoring of analgosedation is of great importance. The aim of this study was to investigate whether monitoring of analgosedative drug concentrations (midazolam and sufentanil) might be beneficial to optimize analgosedation and whether drug serum concentrations correlate with the results of subjective (Richmond Agitation-Sedation Scale [RASS]/Ramsay Sedation Scale) and objective (bispectral (BIS) index) monitoring procedures. Methods: Forty-nine intubated, ventilated, and analgosedated critically ill patients treated in ICU were clinically evaluated concerning the depth of sedation using RASS Score, Ramsay Score, and BIS index twice a day. Serum concentrations of midazolam and sufentanil were determined in blood samples drawn at the same time. Clinical and laboratory data were statistically analyzed for correlations using the Spearman's rank correlation coefficient rho (rho). Results: Average age of the population was 57.8 +/- 16.0 years, 61% of the patients were males. Most frequent causes for ICU treatments were sepsis (22%), pneumonia (22%), or a combination of both (25%). Serum concentrations of midazolam correlated weakly with RASS (rho = - 0.467) and Ramsay Scores (rho = 0.476). Serum concentrations of sufentanil correlated weakly with RASS (rho = - 0.312) and Ramsay Scores (rho = 0.295). Correlations between BIS index and serum concentrations of midazolam (rho = - 0.252) and sufentanil (rho = - 0.166) were low. Conclusion: Correlations between drug serum concentrations and clinical or neurophysiological monitoring procedures were weak. This might be due to intersubject variability, polypharmacy with drug-drug interactions, and complex metabolism, which can be altered in critically ill patients. Therapeutic drug monitoring is not beneficial to determine depth of sedation in ICU patients. PMID- 30302255 TI - Comparative proteomic analysis provides insight into a complex regulatory network of taproot formation in radish (Raphanus sativus L.). AB - The fleshy taproot of radish is an important storage organ determining its yield and quality. Taproot thickening is a complex developmental process in radish. However, the molecular mechanisms governing this process remain unclear at the proteome level. In this study, a comparative proteomic analysis was performed to analyze the proteome changes at three developmental stages of taproot thickening using iTRAQ approach. In total, 1862 differentially expressed proteins (DEPs) were identified from 6342 high-confidence proteins, among which 256 up-regulated proteins displayed overlapped accumulation in S1 (pre-cortex splitting stage) vs. S2 (cortex splitting stage) and S1 vs. S3 (expanding stage) pairs, whereas 122 up regulated proteins displayed overlapped accumulation in S1 vs. S3 and S2 vs. S3 pairs. Gene Ontology (GO) and pathway enrichment analysis showed that these DEPs were mainly involved in several processes such as "starch and sucrose metabolism", "plant hormone signal transduction", and "biosynthesis of secondary metabolites". A high concordance existed between iTRAQ and RT-qPCR at the mRNA expression levels. Furthermore, association analysis showed that 187, 181, and 96 DEPs were matched with their corresponding differentially expressed genes (DEGs) in S1 vs. S2, S1 vs. S3, and S2 vs. S3 comparison, respectively. Notably, several functional proteins including cell division cycle 5-like protein (CDC5), expansin B1 (EXPB1), and xyloglucan endotransglucosylase/hydrolase protein 24 (XTH24) were responsible for cell division and expansion during radish taproot thickening process. These results could facilitate a better understanding of the molecular mechanism underlying taproot thickening, and provide valuable information for the identification of critical genes/proteins responsible for taproot thickening in root vegetable crops. PMID- 30302256 TI - The MADS transcription factor CmANR1 positively modulates root system development by directly regulating CmPIN2 in chrysanthemum. AB - Plant root systems are essential for many physiological processes, including water and nutrient absorption. MADS-box transcription factor (TF) genes have been characterized as the important regulators of root development in plants; however, the underlying mechanism is largely unknown, including chrysanthemum. Here, it was found that the overexpression of CmANR1, a chrysanthemum MADS-box TF gene, promoted both adventitious root (AR) and lateral root (LR) development in chrysanthemum. Whole transcriptome sequencing analysis revealed a series of differentially expressed unigenes (DEGs) in the roots of CmANR1-transgenic chrysanthemum plants compared to wild-type plants. Functional annotation of these DEGs by alignment with Gene Ontology (GO) terms and biochemical pathway Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis indicated that CmANR1 TF exhibited "DNA binding" and "catalytic" activity, as well as participated in "phytohormone signal transduction". Both chromatin immunoprecipitation-polymerase chain reaction (ChIP-PCR) and gel electrophoresis mobility shift assays (EMSA) indicated the direct binding of CmPIN2 to the recognition site CArG-box motif by CmANR1. Finally, a firefly luciferase imaging assay demonstrated the transcriptional activation of CmPIN2 by CmANR1 in vivo. Overall, our results provide novel insights into the mechanisms of MADS-box TF CmANR1 modulation of both AR and LR development, which occurs by directly regulating auxin transport gene CmPIN2 in chrysanthemum. PMID- 30302257 TI - Proteomic analysis of heat stress resistance of cucumber leaves when grafted onto Momordica rootstock. AB - Various biotic and abiotic stresses threaten the cultivation of future agricultural crops. Among these stresses, heat stress is a major abiotic stress that substantially reduces agricultural productivity. Many strategies to enhance heat stress tolerance of crops have been developed, among which is grafting. Here, we show that Momordica-grafted cucumber scions have intrinsically enhanced chlorophyll content, leaf area, and net photosynthetic rate under heat stress compared to plants grafted onto cucumber rootstock. To investigate the mechanisms by which Momordica rootstock enhanced cucumber scions heat stress tolerance, comparative proteomic analysis of cucumber leaves in response to rootstock grafting and/or heat stress was conducted. Seventy-seven differentially accumulated proteins involved in diverse biological processes were identified by two-dimensional electrophoresis (2-DE) in conjunction with matrix-assisted laser desorption/ionization time-of-flight/time-of-flight mass spectrometry (MALDI TOF/TOF MS). The following four main categories of proteins were involved: photosynthesis (42.8%), energy and metabolism (18.2%), defense response (14.3%), and protein and nucleic acid biosynthesis (11.7%). Proteomic analysis revealed that scions grafted onto Momordica rootstocks upregulated more proteins involved in photosynthesis compared to scions grafted onto cucumber rootstocks under heat stress and indicated enhanced photosynthetic capacity when seedlings were exposed to heat stress. Furthermore, the expression of photosynthesis-related genes in plants grafted onto Momordica rootstocks significantly increased in response to heat stress. In addition, increased high-temperature tolerance of plants grafted onto Momordica rootstock was associated with the accumulation of ribulose-1,5 bisphosphate carboxylase/oxygenase (Rubisco) and oxygen-evolving enhancer protein 1 (OEE1). Taken together, the data indicated that Momordica rootstock might alleviate growth inhibition caused by heat stress by improving photosynthesis, providing valuable insight into enhancing heat stress tolerance in the global warming epoch. PMID- 30302258 TI - Transcriptomic analyses identify albino-associated genes of a novel albino tea germplasm 'Huabai 1'. AB - Albinism in shoots of tea plants is a common phenotypic expression which gives the tea infusion a pleasant umami taste. A novel natural albino mutant tea germplasm containing high amino acids content was found and named as 'Huabai 1'. 'Huabai 1' has white jade tender shoots under low temperature and turns green with increased temperature. In order to understand the molecular mechanism of color change in leaf of 'Huabai 1', transcriptome analysis was performed to identify albino-associated differentially expressed genes (DEGs). A total of 483 DEGs were identified from white shoots of 'Huabai 1' compared to its green shoots. There were 15 DEGs identified to be involved in phenylpropanoid biosynthesis, which account for the majority of characterized DEGs. The metabolites related to phenylpropanoid biosynthesis revealed similar expression pattern of DEGs. Furthermore, metabolic pathways such as ubiquonone, tyrosine, and flavonoid biosynthesis associated with phenylpropanoid biosynthesis could also contribute to the color change in 'Huabai 1' tender shoots. Protein-protein interaction analysis revealed a hub protein NEDD8 (CSA009575) which interacted with many regulated genes in spliceosome, nitrogen metabolism, phenylpropanoid biosynthesis, and other pathways. In conclusion, the findings in this study indicate that the color change of 'Huabai 1' tender shoots is a combined effect of phenylpropanoid biosynthesis pathway and other metabolic pathways including flavonoid biosynthesis in tea plants. Chlorophyll biosynthesis-related genes LHCII and SGR may also play some roles in color change of 'Huabai 1'. PMID- 30302259 TI - Multiple haploids, triploids, and tetraploids found in modern-day "living fossil" Ginkgo biloba. AB - Ginkgo biloba, the last extant representative of a lineage of Mesozoic gymnosperms, is one of the few seed plants with an exceptionally long (~300 Myr) evolutionary history free of genome-wide duplications (polyploidy). Despite this genome conservatism, we have recently found a viable spontaneous tetraploid Ginkgo sapling during routine screening of several plants, demonstrating that natural polyploidy is possible in Ginkgo. Here we provide a much wider flow cytometry survey of ploidy in some European Ginkgo collections, and own seedlings (>2200 individuals and ~200 cultivars). We found a surprisingly high level of ploidy variation in modern-day Ginkgo and documented altogether 13 haploid, 3 triploid, and 10 tetraploid Ginkgo plants or cultivars, most of them being morphologically distinct from common diploids. Haploids frequently produced polyploid (dihaploid) buds or branches. Tetraploids showed some genome size variation. The surveyed plants provide a unique resource for future Ginkgo research and breeding, and they might be used to accelerate the modern diversification of this nearly extinct plant lineage.

PMID- 30302260 TI - The USDA cucumber (Cucumis sativus L.) collection: genetic diversity, population structure, genome-wide association studies, and core collection development. AB - Germplasm collections are a crucial resource to conserve natural genetic diversity and provide a source of novel traits essential for sustained crop improvement. Optimal collection, preservation and utilization of these materials depends upon knowledge of the genetic variation present within the collection. Here we use the high-throughput genotyping-by-sequencing (GBS) technology to characterize the United States National Plant Germplasm System (NPGS) collection of cucumber (Cucumis sativus L.). The GBS data, derived from 1234 cucumber accessions, provided more than 23 K high-quality single-nucleotide polymorphisms (SNPs) that are well distributed at high density in the genome (~1 SNP/10.6 kb). The SNP markers were used to characterize genetic diversity, population structure, phylogenetic relationships, linkage disequilibrium, and population differentiation of the NPGS cucumber collection. These results, providing detailed genetic analysis of the U.S. cucumber collection, complement NPGS descriptive information regarding geographic origin and phenotypic characterization. We also identified genome regions significantly associated with 13 horticulturally important traits through genome-wide association studies (GWAS). Finally, we developed a molecularly informed, publicly accessible core collection of 395 accessions that represents at least 96% of the genetic variation present in the NPGS. Collectively, the information obtained from the GBS data enabled deep insight into the diversity present and genetic relationships among accessions within the collection, and will provide a valuable resource for genetic analyses, gene discovery, crop improvement, and germplasm preservation. PMID- 30302261 TI - Differentially expressed protein and gene analysis revealed the effects of temperature on changes in ascorbic acid metabolism in harvested tea leaves. AB - Tea is an important non-alcoholic beverage worldwide. Tea quality is determined by numerous secondary metabolites in harvested tea leaves, including tea polyphenols, theanine, caffeine, and ascorbic acid (AsA). AsA metabolism in harvested tea leaves is affected by storage and transportation temperature. However, the molecular mechanisms underlying AsA metabolism in harvested tea leaves exposed to different storage and transportation temperature conditions remain unclear. Here we performed RP-HPLC to detect dynamic changes in AsA content in tea leaves subjected to high- (38 degrees C), low- (4 degrees C), or room-temperature (25 degrees C) treatments. The AsA distribution and levels in the treated tea leaves were analyzed using cytological-anatomical characterization methods. The differentially expressed CsAPX1 and CsDHAR2 proteins, which are involved in the AsA recycling pathway, were identified from the corresponding proteomic data using iTRAQ. We also analyzed the expression profiles of 18 genes involved in AsA metabolism, including CsAPX1 and CsDHAR2. AsA was mainly distributed in tea leaf mesophyll cells. High- and low-temperature treatments upregulated the CsAPX1 and CsDHAR2 proteins and induced CsAPX and CsDHAR2 gene expression. These results indicated that the CsAPX1 and CsDHAR2 proteins might have critical roles in AsA recycling in tea leaves. Our results provide a foundation for the in-depth investigation of AsA metabolism in tea leaves during storage and transportation, and they will promote better tea flavor in tea production. PMID- 30302263 TI - A 32-year-old man with hypoxemia and bilateral upper-lobe predominant ground glass infiltrates on chest imaging. AB - Diffuse alveolar hemorrhage (DAH) is a rare, but potentially fatal, complication of antiphospholipid syndrome, and may present with acute and fulminant symptoms. We report a case of DAH presenting as sudden onset dyspnea in a gentleman with known antiphospholipid syndrome. Chest computed tomography angiography with pulmonary embolism protocol showed right lower lobe segmental filling defects, upper-lobe predominant diffuse ground-glass opacities, and centrilobular nodules bilaterally. The presence of DAH can be confirmed by bronchoalveolar lavage with serial aliquots, but this procedure typically does not elucidate the specific etiology for the hemorrhage. The treatment for patients with severe disease typically consists of a combination of immunosuppressive medications in the form of high-dose intravenous glucocorticoids plus rituximab, cyclophosphamide or mycophenolate; and/or plasma exchange. This case both provides an example of high quality diagnostic imaging of diffuse alveolar hemorrhage as well as demonstrates the clinical and image-based improvement after treatment. PMID- 30302264 TI - Omphalocele and epigastric heteropagus: implications and treatment. AB - In heteropagus twins, the parasitic twin is incompletely formed which is attached to the autosite. We report a case of epigastric heteropagus twins with omphalocele. The parasite had two lower limbs, a rudimentary upper limb, genitalia with developed phallus and scrotum but absent testis. An omphalocele was present just below the attachment of the parasitic twin. A single kidney with ureter and a bladder filled with urine seen during exploration. The parasite bowel was attached to a sleeve of liver tissue from the autosite within the omphalocele sac and this connection was also the main source of its blood supply. Less than 20 cases of omphalocele with EH have been reported previously. The thin sac with underlying adherent bowel led us to go ahead with surgery in the neonatal period for both, excision of epigastric heteropagus and omphalocele repair. The rectus sheath around the omphalocele sac helped in the final wound closure. PMID- 30302265 TI - Bullous pemphigoid associated with ipilimumab therapy for advanced metastatic melanoma. AB - Immunotherapy is now being routinely used in the management of many cancers. It is therefore vital that all clinicians are aware of the diverse array of cutaneous manifestations that can result from their use, which can vary from mild to life threatening.

AB - Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is characterized by congenital absence of the vagina and uterus. We conducted genome-wide SNP analyses and exome sequencing to detect the causes of MRKH syndrome. We identified de novo variants of MYCBP2, NAV3, and PTPN3 in three families and a variant of MYCBP2 in a sporadic case. Here, we demonstrated the partial genetic makeup of Japanese MRKH syndrome. PMID- 30302267 TI - Predicting 3-Year Survival in Patients Receiving Maintenance Dialysis: An External Validation of iChoose Kidney in Ontario, Canada. AB - Background: Many patients with end-stage kidney disease (ESKD) do not appreciate how their survival may differ if treated with a kidney transplant compared with dialysis. A risk calculator (iChoose Kidney) developed and validated in the United States provides individualized mortality estimates for different treatment options (dialysis vs living or deceased donor kidney transplantation). The calculator can be used with patients and families to help patients make more educated treatment decisions. Objective: To validate the iChoose Kidney risk calculator in Ontario, Canada. Design: External validation study. Setting: We used several linked administrative health care databases from Ontario, Canada. Patients: We included 22 520 maintenance dialysis patients and 4505 kidney transplant recipients. Patients entered the cohort between 2004 and 2014. Measurements: Three-year all-cause mortality. Methods: We assessed model discrimination using the C-statistic. We assessed model calibration by comparing the observed versus predicted mortality risk and by using smoothed calibration plots. We used multivariable logistic regression modeling to recalibrate model intercepts using a correction factor, when appropriate. Results: In our final version of the iChoose Kidney model, we included the following variables: age (18 80 years), sex (male, female), race (white, black, other), time on dialysis (<6 months, 6-12 months, >12 months), and patient comorbidities (hypertension, diabetes, and/or cardiovascular disease). Over the 3-year follow-up period, 33.3% of dialysis patients and 6.2% of kidney transplant recipients died. The discriminatory ability was moderate (C-statistic for dialysis: 0.70, 95% confidence interval [CI]: 0.69-0.70, and C-statistic for transplant: 0.72, 95% CI: 0.69-0.75). The 3-year observed and predicted mortality estimates were comparable and even more so after we recalibrated the intercepts in 2 of our models (dialysis and deceased donor kidney transplantation). As done in the United States, we developed a Canadian Web site and an iOS application called Dialysis vs. Kidney Transplant- Estimated Survival in Ontario. Limitations: Missing data in our databases precluded the inclusion of all variables that were in the original iChoose Kidney (ie, patient ethnicity and low albumin). We were unable to perform all preplanned analyses due to the limited sample size. Conclusions: The original iChoose Kidney risk calculator was able to adequately predict mortality in this Canadian (Ontario) cohort of ESKD patients. After minor modifications, the predictive accuracy improved. The Dialysis vs. Kidney Transplant- Estimated Survival in Ontario risk calculator may be a valuable resource to help ESKD patients make an informed decision on pursuing kidney transplantation. PMID- 30302268 TI - Acute Kidney Injury Due to Inferior Vena Cava Stenosis After Liver Transplantation: A Case Report About the Importance of Hepatic Vein Doppler Ultrasound and Clinical Assessment. AB - Rationale: Acute kidney injury (AKI) is a frequent complication after liver transplantation. In some patients, prompt intervention targeted at a specific etiology is of paramount importance. Presenting concerns of the patients: A 25 years old man with advanced liver cirrhosis caused by sclerosing cholangitis and autoimmune hepatitis underwent orthotopic liver transplantation. One month after surgery, severe AKI developed in conjunction with recurrent ascites and lower extremity edema. Notable clinical findings included a persistently low urinary sodium excretion, a bland urinary sediment, and an abnormally monophasic hepatic vein waveform on Doppler ultrasound. Diagnoses: Inferior vena cava stenosis. Interventions: Angioplasty with stent installation. Outcomes: Rapid improvement of renal function after stent installation. Lessons learned: The following case illustrates the importance of integrating clinical cues, ultrasound features, and laboratory findings. The combination of AKI associated with lower extremity edema, abnormal monophasic hepatic vein flow on Doppler ultrasound, and a low urinary sodium excretion after liver transplantation should evoke the possibility of inferior vena cava stenosis as the etiologic factor.

PMID- 30302272 TI - Culturally congruent mentorship can reduce disruptive behavior among elementary school students: results from a pilot study. AB - Background: Our study objective was to examine the feasibility of implementing a culturally congruent mentorship pilot program, Youth-First (YF), that targets behavior modification among elementary school-aged children with disruptive behavior and a history of school suspension. We hypothesize that it is feasible to implement the YF program to reduce disruptive behaviors and recidivism of level III/IV infractions in school settings among at-risk African American students. Methods: We assessed program feasibility based on the success of program acceptance by parents/guardians, study enrollment, and intervention compliance by students. A pre/posttest study design was used to examine whether the YF program reduced recidivism of disruptive behavior among enrolled at-risk African American elementary school children between September 2016 and January 2017. Generalized linear mixed models examined whether student behavioral scores improved over time and varied by program mentor. A McNemar test examined the reduction in cumulative incidence of level III/IV infractions pre-post YF program intervention. Results: Intervention acceptance, enrollment, and compliance were 100% (95% confidence interval [CI] 86 to 100%), 100% (95% CI 86 to 100%), and 67% (95% CI 45 to 84%), respectively (N = 24). Overall, student behavioral scores improved and plateaued over time (Time2 effect: b = - 0.01, 95% CI - 0.02, < 0.01); a two-week period was associated with a seven-point improvement (effect size: Cohen's d = 0.47, 95% CI 0.03, 0.94) in behavioral scores. Behavioral score improvements were class-specific, based on respectfulness behavior (b = 0.11, 95% CI < 0.01, 0.26). No recidivism of level III/IV infractions was reported during and post YF intervention. Conclusion: The integration of culturally congruent mentorship in elementary school-settings is feasible and can reduce risk of disruptive behaviors among at-risk African American students. Future studies should use randomized clinical trials to determine the effectiveness of culturally congruent mentorship interventions (void of potential selection and confounding biases) in reducing disruptive behavior, level III/IV infractions, and school suspensions among at-risk children. PMID- 30302270 TI - The use of computer-interpretable clinical guidelines to manage care complexities of patients with multimorbid conditions: A review. AB - Clinical practice guidelines (CPGs) document evidence-based information and recommendations on treatment and management of conditions. CPGs usually focus on management of a single condition; however, in many cases a patient will be at the centre of multiple health conditions (multimorbidity). Multiple CPGs need to be followed in parallel, each managing a separate condition, which often results in instructions that may interact with each other, such as conflicts in medication. Furthermore, the impetus to deliver customised care based on patient-specific information, results in the need to be able to offer guidelines in an integrated manner, identifying and managing their interactions. In recent years, CPGs have been formatted as computer-interpretable guidelines (CIGs). This enables developing CIG-driven clinical decision support systems (CDSSs), which allow the development of IT applications that contribute to the systematic and reliable management of multiple guidelines. This study focuses on understanding the use of CIG-based CDSSs, in order to manage care complexities of patients with multimorbidity. The literature between 2011 and 2017 is reviewed, which covers: (a) the challenges and barriers in the care of multimorbid patients, (b) the role of CIGs in CDSS augmented delivery of care, and (c) the approaches to alleviating care complexities of multimorbid patients. Generating integrated care plans, detecting and resolving adverse interactions between treatments and medications, dealing with temporal constraints in care steps, supporting patient-caregiver shared decision making and maintaining the continuity of care are some of the approaches that are enabled using a CIG-based CDSS. PMID- 30302271 TI - Rhamnolipids from Pseudomonas aeruginosa disperse the biofilms of sulfate reducing bacteria. AB - Biofilm formation is an important problem for many industries. Desulfovibrio vulgaris is the representative sulfate-reducing bacterium (SRB) which causes metal corrosion in oil wells and drilling equipment, and the corrosion is related to its biofilm formation. Biofilms are extremely difficult to remove since the cells are cemented in a polymer matrix. In an effort to eliminate SRB biofilms, we examined the ability of supernatants from Pseudomonas aeruginosa PA14 to disperse SRB biofilms. We found that the P. aeruginosa supernatants dispersed more than 98% of the biofilm. To determine the biochemical basis of this SRB biofilm dispersal, we examined a series of P. aeruginosa mutants and found that mutants rhlA, rhlB, rhlI, and rhlR, defective in rhamnolipids production, had significantly reduced levels of SRB biofilm dispersal. Corroborating these results, purified rhamnolipids dispersed SRB biofilms, and rhamnolipids were detected in the P. aeruginosa supernatants. Hence, P. aeruginosa supernatants disperse SRB biofilms via rhamnolipids. To determine the genetic basis of how the P. aeruginosa supernatants disperse SRB biofilms, a whole transcriptomic analysis was conducted (RNA-seq); based on this analysis, we identified four proteins (DVUA0018, DVUA0034, DVUA0066, and DVUA0084) of the D. vulgaris megaplasmid that influence biofilm formation, with production of DVUA0066 (a putative phospholipase) reducing biofilm formation 5.6-fold. In addition, the supernatants of P. aeruginosa dispersed the SRB biofilms more readily than protease in M9 glucose minimum medium and were also effective against biofilms of Escherichia coli and Staphylococcus aureus.

PMID- 30302273 TI - Abnormal gametogenesis induced by p53 deficiency promotes tumor progression and drug resistance. AB - The century-old embryonal/gametogenesis hypothesis of tumors could link diverse tumors' malignant features together likely representing the real "stemness" of tumors. However, the genetic evidence to validate abnormal gametogenesis in tumors remains lacking. Here we show that p53 deficiency elicits abnormal gametogenesis from primordial germ cell-like stage to late oocyte-like stage and subsequent parthenogenetic activation. The similar upregulation of abnormal gametogenesis by p53 deficiency is observed both in p53-/- mouse model and cultured cancer cells. Notably, germ cell-like cells isolated from distinct tumors from p53-/- mice and cancer cell lines display potent tumorigenicity potential. Abnormal oogenesis induced by p53 deficiency and then spontaneous parthenogenetic activation endow tumors with imitated embryonic development, life cycle, and therapeutic resistance. Our study establishes the genetic evidence to support embryonal/gametogenesis theory of tumors and reveals a pivotal role of p53 in restricting abnormal gametogenesis that may represent a novel aspect for p53's tumor suppression. PMID- 30302277 TI - Basal and starvation-induced autophagy mediates parasite survival during intraerythrocytic stages of Plasmodium falciparum. AB - The precise role of autophagy in P. falciparum remains largely unknown. Although a limited number of autophagy genes have been identified in this apicomplexan, only PfAtg8 has been characterized to a certain extent. On the basis of the expression levels of PfAtg8 and the putative PfAtg5, we report that the basal autophagy in this parasite is quite robust and mediates not only the intraerythrocytic development but also fresh invasion of red blood cells (RBCs) in the subsequent cycles. We demonstrate that the basal autophagy responds to both inducers and inhibitors of autophagy. In addition, the parasite survival upon starvation is temporally governed by the autophagy status. Brief periods of starvation, which induces autophagy, help survival while prolonged starvation decreases autophagy leading to stalled parasite growth and reduced invasion. Thus, starvation-induced autophagy is context dependent. Importantly, we report characterization of another autophagy marker in this parasite, the putative PfAtg5 (Pf3D7_1430400). PfAtg5 is expressed in all the intraerythrocytic stages and partially colocalizes with ER, mitochondria, apicoplast and PfAtg8. It is also present on the double membrane bound vesicles. Altogether, these studies pave way for the detailed dissection of P. falciparum autophagy machinery and insights into molecular and functional characterization of its players for developing new therapeutics as antimalarials. PMID- 30302275 TI - Inhibition of glioblastoma cell proliferation, invasion, and mechanism of action of a novel hydroxamic acid hybrid molecule. AB - Glioblastoma multiforme is one of the most aggressive brain tumors and current therapies with temozolomide or suberoylanilide hydroxamic acid (SAHA, vorinostat) show considerable limitations. SAHA is a histone deacetylase (HDAC) inhibitor that can cause undesirable side effects due to the lack of selectivity. We show here properties of a novel hybrid molecule, sahaquine, which selectively inhibits cytoplasmic HDAC6 at nanomolar concentrations without markedly suppressing class I HDACs. Inhibition of HDAC6 leads to significant alpha-tubulin acetylation, thereby impairing cytoskeletal organization in glioblastoma cells. The primaquine moiety of sahaquine reduced the activity of P-glycoprotein, which contributes to glioblastoma multiforme drug resistance. We propose the mechanism of action of sahaquine to implicate HDAC6 inhibition together with suppression of epidermal growth factor receptor and downstream kinase activity, which are prominent therapeutic targets in glioblastoma multiforme. Sahaquine significantly reduces the viability and invasiveness of glioblastoma tumoroids, as well as brain tumor stem cells, which are key to tumor survival and recurrence. These effects are augmented with the combination of sahaquine with temozolomide, the natural compound quercetin or buthionine sulfoximine, an inhibitor of glutathione biosynthesis. Thus, a combination of agents disrupting glioblastoma and brain tumor stem cell homeostasis provides an effective anti-cancer intervention. PMID- 30302276 TI - Metabolic profile and differentiation potential of extraembryonic endoderm-like cells. AB - Glucose metabolism has a crucial role for providing substrates required to generate ATP and regulate the epigenetic landscape. We reported that F9 embryonal carcinoma stem-like cells require cytosolic reactive oxygen species to differentiate into extraembryonic endoderm; however, mitochondrial sources were not examined. To extend these studies, we examined the metabolic profile of early and late-passage F9 cells, and show that their ability to differentiate is similar, even though each population has dramatically different metabolic profiles. Differentiated early-passage cells relied on glycolysis, while differentiated late-passage cells transitioned towards oxidative phosphorylation (OXPHOS). Unexpectedly, electron transport chain protein stoichiometry was disrupted in differentiated late-passage cells, whereas genes encoding mitofusion 1 and 2, which promote mitochondrial fusion and favor OXPHOS, were upregulated in differentiated early-passage cells. Despite this, early-passage cells cultured under conditions to promote glycolysis showed enhanced differentiation, whereas promoting OXPHOS in late-passage cells showed a similar trend. Further analysis revealed that the distinct metabolic profiles seen between the two populations is largely associated with changes in genomic integrity, linking metabolism to passage number. Together, these results indicate that passaging has no effect on the potential for F9 cells to differentiate into extraembryonic endoderm; however, it does impact their metabolic profile. Thus, it is imperative to determine the molecular and metabolic status of a stem cell population before considering its utility as a therapeutic tool for regenerative medicine. PMID- 30302278 TI - YL064 directly inhibits STAT3 activity to induce apoptosis of multiple myeloma cells. AB - Aberrant activation of signal transducer and activator of transcription 3 (STAT3) plays a critical role in the proliferation and survival of multiple myeloma. And inactivation of STAT3 is considered a promising strategy for the treatment of multiple myeloma. Here we show that the sinomenine derivative YL064 could selectively reduce the cell viability of multiple myeloma cell lines and primary multiple myeloma cells. Moreover, YL064 also induces cell death of myeloma cells in the presence of stromal cells. Western blot analysis showed that YL064 inhibited the constitutive activation and IL-6-induced activation of STAT3, reflected by the decreased phosphorylation of STAT3 on Tyr705. Consistent with this, YL064 inhibited the nuclear translocation of STAT3 and the expression of STAT3 target genes, such as cyclin D1 and Mcl-1. Using biotin- and FITC-labeled YL064, we found that YL064 could pull-down STAT3 from myeloma cells and colocalized with STAT3, suggesting that YL064 directly targets STAT3. Cellular thermal shift assay further demonstrated the engagement of YL064 to STAT3 in cells. Molecular docking studies indicated that YL064 may interact with STAT3 in its SH2 domain, thereby inhibiting the dimerization of STAT3. Finally, YL064 inhibited the growth of human myeloma xenograft in vivo. Taken together, this study demonstrated that YL064 may be a promising candidate compound for the treatment of multiple myeloma by directly targeting STAT3. PMID- 30302280 TI - Selective toxicity of tumor treating fields to melanoma: an in vitro and in vivo study. AB - Tumor treating fields (TTFs) are a newly developed cancer therapy technology using an alternating electric field that may be a possible candidate for overcoming the limitations of conventional treatment methods currently used in cancer treatment. Although clinical results using TTFs appear promising, concerns regarding side effects must be clarified to demonstrate the effectiveness of this treatment method. To investigate the side effects of TTF treatment, the damage to normal cell lines and normal tissue of a mouse model was compared with the damage to tumor cells and tumors in a mouse model after TTF treatment. No serious damage was found in the normal cells and normal tissues of the mouse model, suggesting that the side effects of TTF treatment may not be serious. Our evidence based on in vitro and in vivo experiments suggests that TTF may cause selective damage to cancer cells, further demonstrating the potential of TTF as an attractive alternative to conventional cancer treatment modalities. PMID- 30302281 TI - A combination of TLR-4 agonist and saponin adjuvants increases antibody diversity and protective efficacy of a recombinant West Nile Virus antigen. AB - Members of the Flaviviridae family are the leading causes of mosquito-borne viral disease worldwide. While dengue virus is the most prevalent, the recent Zika virus outbreak in the Americas triggered a WHO public health emergency, and yellow fever and West Nile viruses (WNV) continue to cause regional epidemics. Given the sporadic nature of flaviviral epidemics both temporally and geographically, there is an urgent need for vaccines that can rapidly provide effective immunity. Protection from flaviviral infection is correlated with antibodies to the viral envelope (E) protein, which encodes receptor binding and fusion functions. TLR agonist adjuvants represent a promising tool to enhance the protective capacity of flavivirus vaccines through dose and dosage reduction and broadening of antiviral antibody responses. This study investigates the ability to improve the immunogenicity and protective capacity of a promising clinical stage WNV recombinant E-protein vaccine (WN-80E) using a novel combination adjuvant, which contains a potent TLR-4 agonist and the saponin QS21 in a liposomal formulation (SLA-LSQ). Here, we show that, in combination with WN-80E, optimized SLA-LSQ is capable of inducing long-lasting immune responses in preclinical models that provide sterilizing protection from WNV challenge, reducing viral titers following WNV challenge to undetectable levels in Syrian hamsters. We have investigated potential mechanisms of action by examining the antibody repertoire generated post-immunization. SLA-LSQ induced a more diverse antibody response to WNV recombinant E-protein antigen than less protective adjuvants. Collectively, these studies identify an adjuvant formulation that enhances the protective capacity of recombinant flavivirus vaccines. PMID- 30302279 TI - Zebrafish: an emerging real-time model system to study Alzheimer's disease and neurospecific drug discovery. AB - Zebrafish (Danio rerio) is emerging as an increasingly successful model for translational research on human neurological disorders. In this review, we appraise the high degree of neurological and behavioural resemblance of zebrafish with humans. It is highly validated as a powerful vertebrate model for investigating human neurodegenerative diseases. The neuroanatomic and neurochemical pathways of zebrafish brain exhibit a profound resemblance with the human brain. Physiological, emotional and social behavioural pattern similarities between them have also been well established. Interestingly, zebrafish models have been used successfully to simulate the pathology of Alzheimer's disease (AD) as well as Tauopathy. Their relatively simple nervous system and the optical transparency of the embryos permit real-time neurological imaging. Here, we further elaborate on the use of recent real-time imaging techniques to obtain vital insights into the neurodegeneration that occurs in AD. Zebrafish is adeptly suitable for Ca2+ imaging, which provides a better understanding of neuronal activity and axonal dystrophy in a non-invasive manner. Three-dimensional imaging in zebrafish is a rapidly evolving technique, which allows the visualisation of the whole organism for an elaborate in vivo functional and neurophysiological analysis in disease condition. Suitability to high-throughput screening and similarity with humans makes zebrafish an excellent model for screening neurospecific compounds. Thus, the zebrafish model can be pivotal in bridging the gap from the bench to the bedside. This fish is becoming an increasingly successful model to understand AD with further scope for investigation in neurodevelopment and neurodegeneration, which promises exciting research opportunities in the future. PMID- 30302282 TI - AS03-adjuvanted H5N1 vaccine promotes antibody diversity and affinity maturation, NAI titers, cross-clade H5N1 neutralization, but not H1N1 cross-subtype neutralization. AB - Immune responses to inactivated vaccines against avian influenza are poor due in part to lack of immune memory. Adjuvants significantly increased virus neutralizing titers. We performed comprehensive analyses of polyclonal antibody responses following FDA-approved adjuvanted H5N1-A/Indonesia vaccine, administered in presence or absence of AS03. Using Whole Genome Fragment Phage Display Libraries, we observed that AS03 induced antibody epitope diversity to viral hemagglutinin (HA) and neuraminidase compared with unadjuvanted vaccine. Furthermore, AS03 promoted significant antibody affinity maturation to properly folded H5-HA1 (but not to HA2) domain, which correlated with neutralization titers against both vaccine and heterologous H5N1 strains. However, no increase in heterosubtypic cross-neutralization of Group1-H1N1 seasonal strains was observed. AS03-H5N1 vaccine also induced higher neuraminidase inhibition antibody titers. This study provides insight into the differential impacts of AS03 adjuvant on H5N1 vaccine-induced antibody responses that may help optimize vaccine platforms for future vaccines with improved protection against seasonal and pandemic influenza strains. PMID- 30302283 TI - System immunology-based identification of blood transcriptional modules correlating to antibody responses in sheep. AB - Inactivated vaccines lack immunogenicity and therefore require potent adjuvants. To understand the in vivo effects of adjuvants, we used a system immunology-based analysis of ovine blood transcriptional modules (BTMs) to dissect innate immune responses relating to either antibody or haptoglobin levels. Using inactivated foot-and-mouth disease virus as an antigen, we compared non-adjuvanted to liposomal-formulated vaccines complemented or not with TLR4 and TLR7 ligands. Early after vaccination, BTM relating to myeloid cells, innate immune responses, dendritic cells, and antigen presentation correlated positively, whereas BTM relating to T and natural killer cells, as well as cell cycle correlated negatively with antibody responses. Interestingly, similar BTM also correlated with haptoglobin, but in a reversed manner, indicating that acute systemic inflammation is not beneficial for early antibody responses. Analysis of vaccine dependent BTM modulation showed that liposomal formulations induced similar responses to those correlating to antibody levels. Surprisingly, the addition of the TLR ligands appeared to reduce early immunological perturbations and mediated anti-inflammatory effects, despite promoting antibody responses. When pre vaccination BTM were analyzed, we found that high vaccine responders expressed higher levels of many BTM relating to cell cycle, antigen-presenting cells, and innate responses as compared with low responders. In conclusion, we have transferred human BTM to sheep and identified early vaccine-induced responses associated with antibody levels or unwanted inflammation in a heterogeneous and small group of animals. Such readouts are applicable to other veterinary species and very useful to identify efficient vaccine adjuvants, their mechanism of action, and factors related to low responders. PMID- 30302284 TI - Overcoming immunogenicity issues of HIV p24 antigen by the use of innovative nanostructured lipid carriers as delivery systems: evidences in mice and non human primates. AB - HIV is one of the deadliest pandemics of modern times, having already caused 35 million deaths around the world. Despite the huge efforts spent to develop treatments, the virus cannot yet be eradicated and continues to infect new people. Spread of the virus remains uncontrolled, thus exposing the worldwide population to HIV danger, due to the lack of efficient vaccines. The latest clinical trials describe the challenges associated with developing an effective prophylactic HIV vaccine. These immunological obstacles will only be overcome by smart and innovative solutions applied to the design of vaccine formulations. Here, we describe the use of nanostructured lipid carriers (NLC) for the delivery of p24 protein as a model HIV antigen, with the aim of increasing its immunogenicity. We have designed vaccine formulations comprising NLC grafted with p24 antigen, together with cationic NLC optimized for the delivery of immunostimulant CpG. This tailored system significantly enhanced immune responses against p24, in terms of specific antibody production and T-cell activation in mice. More importantly, the capacity of NLC to induce specific immune responses against this troublesome HIV antigen was further supported by a 7-month study on non-human primates (NHP). This work paves the way toward the development of a future HIV vaccine, which will also require the use of envelope antigens. PMID- 30302285 TI - Malaria vaccine candidate based on Duffy-binding protein elicits strain transcending functional antibodies in a Phase I trial. AB - Reticulocyte invasion by Plasmodium vivax requires interaction of the Duffy binding protein (PvDBP) with host Duffy antigen receptor for chemokines (DARCs). The binding domain of PvDBP maps to a cysteine-rich region referred to as region II (PvDBPII). Blocking this interaction offers a potential path to prevent P. vivax blood-stage growth and P. vivax malaria. This forms the rationale for development of a vaccine based on PvDBPII. Here we report results of a Phase I randomized trial to evaluate the safety and immunogenicity of recombinant PvDBPII formulated with glucopyranosyl lipid adjuvant-stable emulsion (GLA-SE). Thirty six malaria-naive, healthy Indian male subjects aged 18-45 years were assigned into three cohorts corresponding to doses of 10, 25 and 50 ug of PvDBPII formulated with 5 ug of GLA-SE. Each cohort included nine PvDBPII/GLA-SE vaccinees and three hepatitis B control vaccine recipients. Each subject received the assigned vaccine intramuscularly on days 0, 28 and 56, and was followed up till day 180. No serious AE was reported and PvDBPII/GLA-SE was well-tolerated and safe. Analysis by ELISA showed that all three doses of PvDBPII elicited antigen-specific binding-inhibitory antibodies. The 50 ug dose elicited antibodies against PvDBPII that had the highest binding-inhibitory titres and were most persistent. Importantly, the antibody responses were strain transcending and blocked receptor binding of diverse PvDBP alleles. These results support further clinical development of PvDBPII/GLA-SE to evaluate efficacy against sporozoite or blood-stage challenge in controlled human malaria infection (CHMI) models and against natural P. vivax challenge in malaria endemic areas. PMID- 30302286 TI - The Relationship between Inter-Arm Blood Pressure Difference and Coronary Artery Disease Severity Calculated by the SYNTAX Score. AB - Objectives: The inter-arm systolic blood pressure difference (IASBPD) is closely related to cardiovascular mortality and morbidity. The SYNTAX score indicates the extent and complexity of coronary artery disease, which are determined by coronary angiography. The aim of our study is to examine the relationship between the IASBPD (which is easily calculated in routine practice) and the SYNTAX score. Methods: 104 patients were included in this cross-sectional study. The IASBPD was calculated by blood pressure measurements obtained simultaneously from both arms. The SYNTAX score was calculated by coronary angiography. Results: Patients were divided into two groups: those with a high SYNTAX score (>=20) and those with a low SYNTAX score (<20). The mean IASBPD values were significantly higher in the group with a high SYNTAX score (>=20) (p<0.001). The patients with IASBPD>=10 were more likely to have a high SYNTAX score compared to the patients with IASBPD<10 (p<0.001). Multiple logistic regression analysis revealed that only the IASBPD values were found to be independently associated with high SYNTAX score (OR: 1.717 (CI: 1.307-2.257), p<0.001). Conclusion: The IASBPD values obtained by only blood pressure measurements are closely related to the extent of coronary artery disease.

AB - Background: Anthocyanins and prebiotics impact overall health and wellness, likely through modulation of the microbiota and the intestinal ecosystem. Objectives: An 8-week open-label study in male and female volunteers with uncomplicated obesity was designed to study the efficacy of an anthocyanin and prebiotic blend in modulating intestinal microbiota and intestinal inflammation. Results: After 8 weeks of daily supplementation, participants had a significant decrease in Firmicutes (p < 0.001) and Actinobacteria (p < 0.001) and a significant increase in Bacteroidetes (p < 0.001). Bowel habits were improved as evidenced by reductions in the severity of bloating (p < 0.05), gas (p=0.035), and abdominal pain (p=0.015) as well as significant improvements in stool consistency (p < 0.05). Finally, a nonsignificant decrease in the inflammatory marker fecal calprotectin was seen (p=0.107). The supplement was safe and well tolerated. Conclusions: The results suggest that regular consumption of the anthocyanin-prebiotic blend positively modulated the intestinal ecosystem and provided insights into the mechanisms of action and its impact on health benefits. PMID- 30302288 TI - Current Innovations in Peripheral Nerve Stimulation. AB - Peripheral nerve stimulation has been used in the treatment of several chronic pain conditions including pain due to peripheral nerve dysfunctions, complex regional pain syndrome, and cranial neuralgias. It has been shown to be effective for chronic, intractable pain that is refractory to conventional therapies such as physical therapy, medications, transcutaneous electrical stimulations, and nerve blocks. Recently, a new generation of peripheral nerve stimulation devices has been developed; these allow external pulse generators to transmit impulses wirelessly to the implanted electrode, and their implantation is significantly less invasive. In this review, we discuss the history, pathophysiology, indications, implantation process, and outcomes of employing peripheral nerve stimulation to treat chronic pain conditions. PMID- 30302290 TI - The Impact of Scientific and Technical Training on Improving Routine Collection of Antenatal Care Data for Maternal and Foetal Risk Assessment: A Case Study in the Province of South Kalimantan, Indonesia. AB - Objectives: First, to assess the impact of scientific and technical training on midwives' abilities in collecting and recording the results of routine antenatal care examinations. Second, to explore midwives' views with regard to factors affecting their abilities to successfully complete the data documentation tasks. Methods: The study was conducted in South Kalimantan, Indonesia (April 2016 October 2017). Nineteen urban and rural midwives were selected. Access to antenatal care information on 4,946 women (retrospective cohort study) and 381 women (prospective cohort study) was granted. A descriptive and exploratory design was used to describe midwives' abilities and challenges pertaining to timely collection and recording of results concerning antenatal care examinations. Results: Scientific and technical training has significantly improved the average amount of recorded antenatal care data (from 17.5% to 62.1%, p-value < 0.0005). Lack of awareness, high workload, and insufficient skills and facilities are the main reasons for the database gaps. Conclusions: The training has equipped midwives with scientific knowledge and technical abilities to allow routine collection of antenatal care data. Provision and adequate use of this information during different stages of pregnancy is crucial as an evidence-based guideline to assess maternal and foetal risk factors to ending preventable mortality. PMID- 30302291 TI - Stochastic Resonance Training Improves Balance and Musculoskeletal Well-Being in Office Workers: A Controlled Preventive Intervention Study. AB - Sixty-two office workers in a Swiss federal department were randomly assigned to a training and a control group. While the training group was instructed to complete 3 stochastic resonance whole-body vibration (SR-WBV) exercises every week for 4 weeks, the control group received no treatment. During this time all participants answered a daily questionnaire concerning their surefootedness, sense of balance, musculoskeletal well-being, and muscle relaxation. Before and after the 4-week SR-WBV intervention, balance was tested with a single-leg stance on a foam mat of the Balance Error Scoring System (BESS) using a SwayStarTM System measuring Total Angle Area (TotAngArea) and Total Velocity Area (TotVelArea). Multilevel results highlighted a significant increase over time for surefootedness and sense of balance (t = 2.491, p = .016), as well as for musculoskeletal well-being and muscle relaxation (t = 2.538, p = .014) in the training group but not in the control group. Balance tests showed improvement of balance in the training group (TotAngArea: Z = 2.550, p = .011; TotVelArea: Z = 3.334, p = .001) but not in the control group. SR-WBV exercise indicated a high compliance during this study (3.87+/-0.45 trainings per week) underlining its benefits for the working context. Especially office workers who spend most of their time in sitting position could profit from SR-WBV exercise to improve balance and reduce the risk of falls. PMID- 30302292 TI - Osseointegrated Transcutaneous Device for Amputees: A Pilot Large Animal Model. AB - Traditional above-the-knee amputation prosthetics utilize a stump-socket interface that is well-known for skin/socket problems, sitting difficulty, disuse osteopenia, and increased work of ambulation. As a result, we evaluated a novel osseointegrated transcutaneous implant in a large animal. The implant was designed to promote osseointegration at the bone-implant interface and minimize complications. As proof of concept, four Dorset sheep underwent a two-stage surgery for forelimb placement of an osseointegrated transcutaneous implant utilizing Compress(r) technology (Biomet, Inc., Warsaw, IN). Two sheep received a long anchor plug (90 mm long x 9 mm in diameter) and two received a short anchor plug (46 mm long x 9 mm in diameter). Sixteen weeks after the initial surgery, the operative limbs, along with the attached implant, underwent radiographic and histological analysis for osseointegration. Periprosthetic fractures occurred in the two animals that received the longer internal prosthesis; one healed with splinting and the other animal underwent a second surgical procedure to advance the amputation site more proximal. No fractures occurred in the shorter internal prosthesis group. There was no histological evidence of infection and none of the transcutaneous adapters failed. Bone-implant osseointegration was demonstrated in two of three limbs that underwent histological analysis. This unique implant demonstrated osseointegration without transcutaneous adapter failure, all while displaying minimal infection risk from the outside environment. Although it involved short-term follow-up in a limited number of animals, this pilot study provides a platform for further investigation into the valid concept of using Compress(r) technology as an endo-exo device. PMID- 30302289 TI - Crystallography and Its Impact on Carbonic Anhydrase Research. AB - X-ray and neutron crystallography are powerful techniques utilized to study the structures of biomolecules. Visualization of enzymes in complex with substrate/product and the capture of intermediate states can be related to activity to facilitate understanding of the catalytic mechanism. Subsequent analysis of small molecule binding within the enzyme active site provides insight into mechanisms of inhibition, supporting the design of novel inhibitors using a structure-guided approach. The first X-ray crystal structures were determined for small, ubiquitous enzymes such as carbonic anhydrase (CA). CAs are a family of zinc metalloenzymes that catalyze the hydration of CO2, producing HCO3 - and a proton. The CA structure and ping-pong mechanism have been extensively studied and are well understood. Though the function of CA plays an important role in a variety of physiological functions, CA has also been associated with diseases such as glaucoma, edema, epilepsy, obesity, and cancer and is therefore recognized as a drug target. In this review, a brief history of crystallography and its impact on CA research is discussed. PMID- 30302293 TI - Primary Carnitine Deficiency: A Rare, Reversible Metabolic Cardiomyopathy. AB - A 24-year-old female with a diagnosis of primary carnitine deficiency, a rare inherited metabolic disorder predominantly described in the paediatric literature that causes cardiomyopathy, presented for evaluation after three months of nonadherence with prescribed carnitine therapy. Initial echocardiography demonstrated severe left ventricular dilation (104 ml/m2) (normal < 76 ml/m2) with moderate systolic dysfunction (ejection fraction 40%) and severe right ventricular dilation with mild systolic dysfunction. Carnitine replacement was commenced, and a cardiac magnetic resonance imaging (MRI) performed five days later demonstrated dramatic improvement in biventricular function with normalization of left and right ventricular systolic function. To our knowledge, this is only the second case describing the rapid reversal of cardiomyopathy in an adult patient with this rare condition. PMID- 30302294 TI - A Novel Double Side Branch Protection Technique for a Left Main Trifurcation Lesion: Simultaneous Jailed Balloon and Jailed Corsair Technique. AB - Percutaneous coronary intervention for left main trifurcation disease is challenging. Although side branch protection techniques such as the jailed balloon technique and jailed Corsair technique are the established methods for treatment of coronary bifurcation lesions, little is known regarding the application and feasibility of these techniques for left main trifurcation disease. We herein describe a 72-year-old man with angina pectoris who was successfully treated with percutaneous coronary stent implantation for a left main trifurcation lesion. In this case, we performed a novel double side branch protection technique, the simultaneous jailed balloon and jailed Corsair technique, with a single 8 Fr guiding catheter. This is the first case report to highlight the feasibility and efficacy of combined use of the jailed balloon and jailed Corsair techniques during percutaneous coronary intervention for left main trifurcation disease. PMID- 30302295 TI - Successful Treatment of Severe Type B Lactic Acidosis in a Patient with HIV/AIDS Associated High-Grade NHL. AB - Type B lactic acidosis is a rare metabolic complication sometimes associated with hematologic malignancies. When present, this type of lactic acidosis is most commonly seen in patients with high-grade lymphomas or leukemias and is usually indicative of a dismal prognosis. We report a case of a 27-year man with acquired immunodeficiency syndrome (AIDS) that presented with bilateral lower extremity swelling, an abdominal mass, and weight loss. His lab values showed elevated anion gap with lactic acidosis and computed tomography (CT) of the abdomen showed a large soft-tissue mass arising from the left hepatic lobe. Biopsy of the abdominal mass demonstrated a high-grade diffuse large B-cell lymphoma. The patient's lactic acidosis resolved after starting chemotherapy, and a complete response was evident on PET-CT after a third cycle of rituximab, etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (EPOC-RR). Care-givers should be aware of the implications of lactic acidosis associated with malignancy and the need for prompt diagnosis and treatment. PMID- 30302296 TI - A Case of Intrathoracic Gastric Duplication Cyst Detected on Prenatal Ultrasound Examination. AB - A 37-year-old (G4P3) woman was referred to our hospital at 32 weeks of gestation for the evaluation of a fetus with an intrathoracic cystic lesion. Ultrasonography and magnetic resonance imaging revealed that a fetal cystic lesion without a mucosal layer was located in the posterior mediastinum. These findings were consistent with a bronchogenic cyst. At 38 3/7 weeks of gestation, an elective cesarean section was performed because of her previous cesarean section. A female neonate without any external anomalies, weighing 2,442 g, with Apgar scores of 8 and 9, and requiring no resuscitation was born. Four weeks after delivery, the neonate was admitted because of respiratory distress due to mass effect. At right lateral thoracotomy, a 105 * 65 mm of solitary smooth walled cyst containing serosanguineous fluid was found in the posterior mediastinum, which was excised completely. Histologic examination revealed the diagnosis of the mediastinal gastric duplication cyst. The neonate made an uneventful recovery. Accurate diagnosis is not necessary, but detection and continuous observation are logical. Although gastric duplication, particularly intrathoracic, is a rare pathology, it should be considered in the differential diagnosis of any intrathoracic cyst. PMID- 30302298 TI - Assessment and Retrieval of Aspirated Tracheoesophageal Prosthesis in the Ambulatory Setting. AB - Tracheoesophageal prosthesis (TEP) is the most common voice restoration method following total laryngectomy. Prosthesis extrusion and aspiration occurs in 3.9% to 6.7% and causes dyspnea. Emergency centers are unfamiliar with management of the aspirated TEP. Prior studies report removal of aspirated TEP prostheses under general anesthesia. Laryngectomees commonly have poor pulmonary function, posing increased risks for complications of general anesthesia. We present a straightforward approach to three cases of aspirated TEP prosthesis removed in the ambulatory setting. In each case, aspirated TEP was diagnosed with flexible bronchoscopy under local anesthesia at the time of consultation, and all prostheses were retrieved atraumatically using a biopsy grasper forceps inserted via the side channel of the bronchoscope. The aspirated TEP prosthesis can be safely and efficiently removed via bedside bronchoscopy. PMID- 30302297 TI - Breakage in Two Points of a Short and Undersized "Affixus" Cephalomedullary Nail in a Very Active Elderly Female: A Case Report and Review of the Literature. AB - Introduction: Trochanteric fractures of the femur are common in elderly individuals with osteoporosis. The use of cephalomedullary nails is increasing, and they are now the most commonly used fixation devices, especially for the treatment of unstable trochanteric fractures. The nail breakage is not the most common complication of intramedullary nailing. Many scientific papers report nail breakage in a specific location: through the lag screw hole, the nail shaft, or the distal locking hole. Materials and Methods: We present a case of an 84-year old patient treated with modular revision hip arthroplasty due to the breakage in two points of a cephalomedullary nail implanted 3 years earlier for a subtrochanteric fracture. Results: After modular revision hip arthroplasty, the functional results and quality of life have been excellent. Conclusions: As far as we could determine, this appears to be the first case of a breakage of a cephalomedullary nail in two points after nonunion in a very active elderly female. PMID- 30302299 TI - Two Cases of Sinonasal Non-Intestinal-Type Adenocarcinoma with Squamoid Morules Expressing Nuclear beta-Catenin and CDX2: A Curious Morphologic Finding Supported by Molecular Analysis. AB - Sinonasal non-intestinal-type adenocarcinoma (non-ITAC) is a rare, morphologically diverse neoplasm of the head and neck. Squamoid morular metaplasia has recently been reported as an occasional finding in non-ITAC. Interestingly, these squamoid morules often show aberrant expression of CDX2 as well as nuclear expression of beta-catenin, similar to other tumors that show this type of metaplasia, but the underlying mechanism responsible for this finding is not completely understood. We present two cases of low-grade non-ITAC with squamoid morules coexpressing CDX2 and nuclear beta-catenin by immunohistochemistry, both of which were found to harbor a mutation in CTNNB1, the gene encoding beta-catenin. This finding provides support that an alteration in the beta-catenin pathway, including mutations in the beta-catenin gene itself, is responsible for this recently described morphologic phenomenon in non-ITAC. PMID- 30302300 TI - Determination of Phosphorus in Soil by ICP-OES Using an Improved Standard Addition Method. AB - In this study, an improved standard addition method (ISAM) was developed for the determination of phosphorus in soil by ICP-OES based on the conventional standard addition method (CSAM) and calibration curve method (CCM). Certified standard soils were analyzed by the proposed ISAM method. The values obtained by ISAM method agreed with the certified values. Additionally, the results obtained by ISAM method were compared with those determined by the other two methods (CSAM and CCM). All the values obtained by the ISAM agreed with those from the other two methods. The detection limit, quantification limit, and recovery rate of each method were calculated, and the recovery rates of soil samples and the blank were all within the range of 90%-110%. Finally, the proposed method was applied to determine phosphorous in soil samples from Guangnan County, Yunnan Province, China, and the meadow soil from Qinghai-Tibet Plateau, China. The relative errors between the results from ISAM and CCM were all within 10%, and t-test showed that the results between ISAM and CCM had no significant difference (P > 0.05). Therefore, the proposed method overcame the matrix effect in some extent and was an acceptable method for the rapid and accurate batch analysis of P content in soil sample, especially batch samples with obvious matrix effect. PMID- 30302302 TI - Construction of the Pentacyclic Core and Formal Total Synthesis of (rac) Renieramycin T. AB - Invited for this month's cover picture is the group of Professor Naoki Saito at the Graduate School of Pharmaceutical Sciences, Meiji Pharmaceutical University (Japan). They achieved the first total synthesis of renieramycin T in 2016, and they have been following an alternative route to supply a large amount of it in order to promote research of the next stage, such as structure-activity relationship studies. This paper reports a formal total synthesis in 21 steps from a known piperazine-2,5-dione derivative. The key step of this synthesis is the modified Pictet-Spengler cyclization of a primary amine with an oxomalonic acid ester derivative followed by decarboxylation, and stereo-controlled protonation at C-1 position of the enol intermediate from the less-hindered face.

AB - Aim This study aims to evaluate the long-term complications, results, and patient satisfaction rates of a dorsally approached ulnar shortening osteotomy for ulnar impaction syndrome. Methods A retrospective chart review of 20 patients was performed. Primary outcomes of interest were subjective, measured using the Patient-Rated Wrist Evaluation (PRWE) score, Disability of the Arm, Shoulder, and Hand (DASH) score, and the third questionnaire about patient satisfaction, composed by the authors. Secondary outcomes included hardware removal due to irritation and other complications. Results Mean postoperative functional score of PRWE was 28 (standard deviation [SD], 30) and DASH 20 (SD, 26), respectively. Fifteen patients were satisfied with the operation. Removal of hardware was noted in six patients. In one patient plate breakage occurred. Conclusion Similar postoperative functional scores and complications were seen in patients undergoing an ulnar shortening osteotomy with a dorsally placed plate for ulnar impaction syndrome, compared with other plate placement localizations. The incidence of plate removal is also comparable to previously described results. As the dorsally placed plate and freehand technique, are relatively easy, we feel that it has a place in the treatment of ulnar impaction syndrome. Level of Evidence Level IV, retrospective cohort study. PMID- 30302303 TI - Spaced TiO2 Nanotubes Enable Optimized Pt Atomic Layer Deposition for Efficient Photocatalytic H2 Generation. AB - In the present work, we report the use of TiO2 nanotube (NT) layers with a regular intertube spacing that are decorated by Pt nanoparticles through the atomic layer deposition (ALD) of Pt. These Pt-decorated spaced (SP) TiO2 NTs are subsequently explored for photocatalytic H2 evolution and are compared to classical close-packed (CP) TiO2 NTs that are also decorated with various amounts of Pt by using ALD. On both tube types, by varying the number of ALD cycles, Pt nanoparticles of different sizes and areal densities are formed, uniformly decorating the inner and outer walls from tube top to tube bottom. The photocatalytic activity for H2 evolution strongly depends on the size and density of Pt nanoparticles, driven by the number of ALD cycles. We show that, for SP NTs, a much higher photocatalytic performance can be achieved with significantly smaller Pt nanoparticles (i.e. for fewer ALD cycles) compared to CP NTs. PMID- 30302304 TI - Giant Calvarial Ewing's Sarcoma: A Case Report. AB - Ewing's sarcoma (EWS) is the second most common primary bone tumor seen in children and adolescents, first being osteosarcoma. Skull lesions are seen in 6 to 9% of cases. The tumor tends to reside most frequently on frontal and parietal bones. In the literature, majority of papers on calvarial EWS present cases with intracranial involvement; extracranial extension is reported in only eight cases. The case that we are presenting in this report is a 23-year-old male patient with multiple infiltrations in femur, costal bones, and calvarium which had been diagnosed radiologically and histopathologically as EWS. The calvarial metastasis had reached a very huge size with dimensions of approximately 7.5 * 7.5 * 9.5 cm and was successfully excised totally. Twelve months of follow-up revealed no recurrence in the surgical site showing that total removal of giant cranial EWS may improve morbidity of these patients. PMID- 30302305 TI - Evaluation of the styloid process in a Sri Lankan population using digital panoramic radiographs. AB - Objective: The objectives of this study were to evaluate the normal radiographic length of the styloid process (SP), prevalence and type of elongation, and angulation of the styloid process in relation to sex and side on digital panoramic radiographs in a Sri Lankan population. Methods: A total of 100 digital panoramic images selected from the database at the Division of Oral Medicine and Radiology, Faculty of Dental Sciences, University of Peradeniya, Sri Lanka were evaluated for the radiological features of the styloid process. Lengths greater than 30 mm were consider as elongated. Elongated styloid processes were also classified into three types based on Langlais classification (elongated, pseudo articulated; and segmented). Results: The mean radiological length of the SP on the right and left side was 25.8 mm +/- 7.5 mm and 23.2 mm +/- 9.0 mm respectively. The prevalence of elongated styloid process in males and female were 34.9% and 24.6%. The maximum length observed on right and left sides were 43.2 mm and 41 mm respectively. However, the differences between the genders and the sides were statistically not significant (P = 0.199). The most frequently observed type of elongation was type I (elongated) according to the Langlais classification. Conclusion: This study provides valuable knowledge of the anatomical variations of the SP which may help clinicians from various specialties to diagnose the Eagle syndrome. PMID- 30302306 TI - A case of disseminated tuberculosis mimicking metastatic cancer. AB - Background: Disseminated tuberculosis (TB) or miliary TB is defined as lymphohematogenous dissemination of Mycobacterium tuberculosis bacilli, which may then affect virtually any organ system. The multiple organ involvement in disseminated TB can mimic metastatic cancer and can make the diagnosis challenging. False negatives are common therefore repeating microbiologic and histologic samples is essential. Case report: We report the case of a young immunocompetent patient presenting with multiple atypical extra-pulmonary TB involvement. The patient presented with pulmonary, pleural, bilateral testicular and multiple bone involvement including calcanerium abscesses. These lesions were initially described as metastasis by the radiologist. Therefore lymphoma and metastatic testicular cancer as well as TB were high on the differential in this young foreign-born male. Pleural, broncho-alveolar lavage, bone marrow and cerebrospinal fluid acid-fast bacilli smear and microbiologic culture were all negative. However the histologic examination of the trans-bronchial biopsy and pleural biopsy showed necrotizing granuloma and helped to narrow down the diagnosis. The patient improved with RIPE therapy. Conclusion: This case illustrates the diagnostic difficulty of disseminated TB with atypical organ involvement. Culture is the gold standard for diagnosing TB but is a long process and with 23% of culture negative TB in the United-States, the diagnosis sometimes relies on thoroughly ruling-out differential diagnosis and histologic examination. PMID- 30302307 TI - Successful treatment of steroid-refractory double-positive ANCA and anti-GBM disease with a combination of plasma exchange and immunosuppression: A case report and literature review. AB - The concurrence of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and anti-glomerular basement membrane (GBM) disease, known as double-positive disease, is rare, but it occurs at a much higher frequency than expected by chance. Double-positive disease has an aggressive clinical course, with no optimal treatment strategy. Here we describe a patient with steroid refractory double-positive disease who was treated successfully with the addition of plasma exchange (PE) and cyclophosphamide (CPA). A 78-year-old Japanese woman who was diagnosed with diffuse alveolar hemorrhage and rapidly progressive glomerulonephritis received two cycles of pulse steroid therapy. However, her respiratory and renal condition deteriorated. She was found to be positive for both myeloperoxidase-ANCA and anti-GBM antibodies. The combination of PE and CPA improved her systemic condition. This is the first case report of a patient with steroid-refractory double-positive disease who was successfully treated with the addition of PE and CPA. The marked contrast in therapeutic response to corticosteroids alone and the addition of PE and CPA in this case strongly implies that earlier induction of combination therapy aimed at rapid removal of pathogenic autoantibodies and prevention of ongoing antibody production might improve the outcome of this life-threatening disease. PMID- 30302308 TI - A unique case report of endobronchial cryptococcosis and review of the literature. AB - Cryptococcosis is an infection caused by the yeast-like fungus Cryptococcus neoformans. Pulmonary cryptococcosis is typically identified as a single mass or as multiple nodules, while endobronchial lesions are quite rare. Here we report an uncommon case of pulmonary cryptococcosis presenting as endobronchial lesion in an immunocompetent patient. A 49-year-old male patient complained of intermittent cough with hemoptysis for two years. Computerized tomography of the chest showed a filling defect in the basal segment of the right lower lobe bronchus. A flexible bronchoscopic examination revealed a white smooth-surfaced polypoid lesion completely occluding the medial basal segment of the right lower lobe bronchus. The diagnosis was confirmed by bronchial biopsy under bronchoscopy, and the histopathologic findings showed the organisms were Cryptococcal neoformans. The patient was treated with fluconazole at a dose of 400 mg daily. The endobronchial lesion was found rapidly diminished after 18 days of therapy, and disappeared after 6.5 months of therapy by repeated fiberoptic bronchoscopy. Then the patient continued fluconazole for another 2.5 months. During the total 16 months' follow-up visits, the patient repeated CT scanning for five times, the results of which were all normal. The patient's symptoms disappeared as well, and now he is still under follow-up. This case highlights the fact that pulmonary cryptococcosis can present as endobronchial lesions even in immunocompetent subjects, mimicking lung tumor. Pathological confirmation is important to establish the definite diagnosis. PMID- 30302310 TI - Prevalence of Capillaria plica in Danish wild carnivores. AB - Capillaria plica is a parasitic nematode belonging to the family Capillariidae. The adult parasites reside in the urinary tract of wild and domestic canines. The infection is most often asymptomatic, but can cause a wide range of symptoms including urinary bladder inflammation, pollacisuria, dysuria and hematuria. Canines acquire the infection by ingesting the intermediate host, the earthworm (Lumbricidae). Epidemiological studies on C. plica infection in wildlife are few and only one previous Danish study examined the prevalence in red foxes, while studies on prevalence in other animals are limited. We examined the urine sediment or urinary bladder from 375 Raccoon dogs (Nyctereutes procyonoides), 247 red foxes (Vulpes vulpes), 20 beech martens (Martes foina), 16 wild mink (Neovison vison), 14 otters (Lutra lutra), nine European polecats (Mustela putorius), three European badgers (Meles meles) and one golden jackal (Canis aureus) received as a part of Danish wildlife surveillance. Capillaria plica was detected in 73.7% of red foxes, 20.0% of beech martens, 0.5% of raccoon dogs, and in the Golden jackal. Red foxes originating from all 5 regions of Denmark were infected, although with a significantly higher prevalence in the three regions in Jutland compared to Region Zealand. PMID- 30302309 TI - IgG4-related disease presenting with combined pulmonary fibrosis and emphysema (CPFE). AB - A 64-year-old man was admitted to our hospital with an abnormal chest shadow. The patient was a current-smoker and had a past illness of autoimmune pancreatitis with a high serum level of IgG4, 348 mg/dL. Chest CT showed upper-lobe emphysema, and lower-lobe reticulation with honeycombing, suggestive of combined pulmonary fibrosis with emphysema (CPFE). Surgical lung biopsy was revealed a usual interstitial pneumonia pattern with marked infiltration of IgG4-positive plasma cells. The patient was diagnosed with IgG4 related disease (IgG4-RD) presenting with CPFE. Pulmonary manifestation was improved by corticosteroid therapy. IgG4 RD may be an underlying condition in patient with CPFE. PMID- 30302311 TI - Molecular confirmation of Hymenolepis hibernia in field mice (Apodemus sylvaticus) from St Kilda has potential to resolve a host-parasite relationship. AB - Insular wildlife populations provide opportunities to examine biological questions in systems that are relatively closed and potentially tractable, striking examples being the long-term studies of ecology and evolution in the red deer and feral sheep populations on the Hebridean islands of Rum and St Kilda. In the case of parasitology, Understanding of parasitic infections insular wildlife populations in conjunction with knowledge of their origins has the potential to add a fresh perspective to disease control in humans and domestic animals. In the case of parasitology, understanding infections of insular wildlife populations, in conjunction with knowledge of their origins, has the potential to add a fresh perspective to disease control in humans and domestic animals. With this in mind, gross and molecular examination for the presence of cyclophyllidean tapeworms was performed on the viscera and rectal contents of 17 preserved specimens of Apodemus sylvaticus field mice and on the naturally voided faeces of a further four mice on the remote archipelago of St Kilda. Molecular speciation of hexacanth embryos extracted from the faeces of two mice, using nucleotide sequence analysis of the ribosomal cytochrome c-oxidase subunit-1, confirmed infection with Hymenolepis hibernia. Phylogenetic analysis showed that these were genetically distinct from Hymenolepis diminuta, previously reported in the insular A. sylvaticus mice, and from other published H. hibernia haplotypes. There was insufficient hymenolepidid tapeworm phylogeographic variation to resolve the origins of the co-evolved St Kilda mice, primarily due to a lack of published H. hibernia Cox-1 sequence data across the parasite's geographical range. Nevertheless, the Maximum Likelihood haplotype tree shows the potential for molecular parasitology to resolve a host-parasite relationship once more data become available. Morphological diagnostic features of zoonotic H. hibernia eggs are also described. PMID- 30302312 TI - Helminth parasites of alien freshwater fishes in Patagonia (Argentina). AB - A survey of the helminth parasites of alien freshwater fishes from Argentinean Patagonia is presented, based on samples taken from 2010 to 2017 and including previous published records. A total of 1129 fishes were collected, belonging to 11 species from 7 families. We surveyed 34 localities in 12 river basins, and found 43 parasite taxa (15 digeneans, 14 monogeneans, 5 cestodes, 5 nematodes, and 4 acanthocephalans), belonging to 22 families. Data are presented as a parasite/host list with information on host species and localities, site of infection, parasite life-history stage, origin, previous records in Patagonia, and accession numbers to vouchers. The most frequently found helminths were monogeneans and digeneans. Our data suggest that invading fish in Patagonia have transmitted fewer parasite species than they have received by spillback. Twenty three (53%) of the parasites seem to be acquired by the exotic fishes from native hosts, while 15 helminths were co-introduced along with their exotic fish host and continue to parasitize these alien fish but did not invade native hosts; 4 of these species were introduced with carp, 3 with Cheirodon interruptus, 3 with Corydoras paleatus, 3 with Cnesterodon decemmaculatus, 1 with Oncorhynchus tshawytscha, and 1 with Jenynsia multidentata. The majority of these co introduced parasites came from the Brazilic ichthyogeographic region (10 species). This is the first review of helminth parasites of alien fishes in Argentina; in total 12 new records of parasites for Argentina, 6 new records of parasites for Patagonia, and 29 new host-parasite records are presented here. This list is far from complete, however, given that some basins in southern Patagonia remain unexplored in terms of parasite detection.

AB - Aims: To understand the paradox of an increased fracture risk despite increased bone mineral density (BMD) in persons with type 2 diabetes (DM2). Patients and Methods: We studied 80 old persons with DM2. Mineral metabolism, parathyroid hormone (PTH), 25-hydroxyvitamin D (25OHD), bone turnover - osteocalcin, procollagen type 1 N-terminal propeptide (P1NP) and C-terminal telopeptide of type 1 collagen (CTX) - were measured and BMD was assessed at the lumbar spine (LS) and femoral neck (FN). Data was analyzed with the Statistical Package for the Social Sciences Program. Results: Low levels of 25OHD (84%) and high values of PTH (20%) were found. Osteocalcin was directly related to CTX, p < 0.001, with increased bone formation and increased BMD (z-score) at LS and FN. PTH was directly related to osteocalcin and CTX and inversely related to BMD at the FN, p < 0.05. Patients with dyslipidemia presented higher P1NP, p < 0.05 and patients with hypertension presented higher BMD at LS and FN, p < 0.01. Conclusion: Old type 2 diabetics present increased bone formation, PTH-driven. Low grade secondary hyperparathyroidism may explain the paradox of an increased fracture risk despite increased BMD.

AB - Background: Active restraint for the elbow joint is provided by the soft tissue component, which consists of a musculoligamentous complex. A lesion of the lateral collateral ligament complex (LCLC) is thought to be the primary cause of posterolateral rotatory instability in the elbow. Its role as a protective reflexogenic structure is supported by the existence of ultrastructural mechanoreceptors. The aim of this study was to describe the existence and distribution of LCLC mechanoreceptors in the human elbow joint and to determine their role in providing joint stability. Methods: Eight LCLCs were harvested from fresh frozen cadaver elbows. Specimens were carefully separated from the lateral epicondyle and ulna. The ligament complex was divided into 7 regions of interest and stained with modified gold chloride. Microscopic evaluation was performed for Golgi, Ruffini, and Pacinian corpuscles. The number, distribution, and density of each structure were recorded. Results: Golgi, Ruffini, and Pacinian corpuscles were observed in LCLCs, with variable distribution in each region of interest. Ruffini corpuscles showed the highest total mechanoreceptor density. Mechanoreceptor density was higher at bony attachment sites. Conclusion: The existence and role of each mechanoreceptor defined the purpose of each region of interest. Mechanoreceptors are beneficial for its proprioceptive feature towards a successful elbow ligament reconstruction.

AB - Introduction: There is still controversy regarding the bio-enhanced non reconstructive ACL treatment. Materials and methods: A search for articles in databases was performed in February 2017. The objective and subjective evaluations of clinical studies and biomechanical and histological data of preclinical studies were extracted. Results: Eighteen articles were included for analysis. In clinical studies, although subjective scores were significantly improved, the rate of re-operation rate was high. In preclinical studies, bio enhancing techniques demonstrated promotion of the healing of ACL. Conclusions: The efficacy of biological enhancement cannot be validated in clinical studies. Preclinical studies showed improved biomechanical and healing potential. PMID- 30302316 TI - A cadaveric study on the anatomy of anterior cruciate ligament in Vietnamese adults. AB - Objectives: To report the anatomical characteristics of the ACL in Vietnamese individuals. Subjects and methods: Ten fresh knees were dissected to investigate the anatomical characteristics of ACL. The insertion position, length and diameter of ACL were measured. Results: The average lengths of AM and PL bundle of the ACL were 30.6 mm and 25.6 mm, respectively. The average sizes of the femoral and tibial ACL attachment sites were 13.8 * 10.6 mm and 13.4 * 10.2 mm, respectively. Conclusion: The anatomical characterisitcs of the ACL in Vietnamese individuals were reported.

AB - Measurement of greenhouse gas (GHG) flux using static chamber methods typically occurs immediately following sample collection. However, situations may arise requiring sample storage prior to analysis by gas chromatography. The objective of this study was to determine effects of storage time and temperature on carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) concentrations in vials containing "low" and "high" concentrations of certified standards. Samples were stored for 3, 7, 14, 28, and 84 days at four storage temperatures: room temperature, 25 degrees C, 4 degrees C, and -10 degrees C. Results indicated low and high concentration standards were not impacted by sample storage up to 28 days at any storage temperature. After 84 days, CO2 concentrations were 0.6-14.4% lower than expected while CH4 concentrations were up to 22% greater than expected. Results from future studies will allow for further refinement of scientifically supported guidance regarding appropriate storage temperature and time of GHG samples. *Few studies have examined impacts of storage time and temperature on GHG samples retained in traditional septa-capped vials.*Effects of storage time and temperature on GHG samples were examined.*Based on this study, GHG samples can be stored for up to 28 days at temperatures ranging from -10 degrees C to 25 degrees C. PMID- 30302317 TI - The impact of schizophrenia and intelligence on the relationship between age and brain volume. AB - Age has been shown to have an impact on both grey (GM) and white matter (WM) volume, with a steeper slope of age-related decline in schizophrenia compared to healthy controls. In schizophrenia, the relation between age and brain volume is further complicated by factors such as lower intelligence, antipsychotic medication, and cannabis use, all of which have been shown to have independent effects on brain volume. In a study of first-episode, antipsychotic-naive schizophrenia patients (N = 54) and healthy controls (N = 56), we examined the effects of age on whole brain measures of GM and WM volume, and whether these relationships were moderated by schizophrenia and intelligence (IQ). Secondarily, we examined lifetime cannabis use as a moderator of the relationship between age and brain volume. Schizophrenia patients had lower GM volumes than healthy controls but did not differ on WM volume. We found an age effect on GM indicating that increasing age was associated with lower GM volumes, which did not differ between groups. IQ did not have a direct effect on GM, but showed a trend-level interaction with age, suggesting a greater impact of age with lower IQ. There were no age effects on WM volume, but a direct effect of IQ, with higher IQ showing an association with larger WM volume. Lifetime cannabis use did not alter these findings significantly. This study points to effects of schizophrenia on GM early in the illness, before antipsychotic treatment is initiated, suggesting that WM changes may occur later in the disease process. PMID- 30302319 TI - An index for discrimination of mangroves from non-mangroves using LANDSAT 8 OLI imagery. AB - Over the last few decades several vegetation indices were used to map Mangrove forest using satellite images. Difficulty still persists in discrimination of mangroves from non-mangrove vegetation, especially in areas where mangrove species are mixed with other vegetation types. In the present study we have attempted to develop an improved index, which utilizes the information from the Normalized Difference Vegetation Index (NDVI) and the Normalized Difference Water Index (NDWI) of Bhitarkanika mangrove forest of Odisha, India. These indices are negatively correlated (r = -0.988; p < 0.01). Further, the NDWI values were subtracted from the NDVI values at the pixel level. As the outputs are negatively related, subtraction increases the upper and lower range of the overall output, also increasing the distinct values of two classes with near-similar spectral signatures. Same algorithm was applied on mangroves of Sundarbans (r = -0.987) and Andaman (r = -0.989). A comparison between four established indices [NDVI, NDWI, Soil Adjusted Vegetation Index (SAVI), Simple Ratio (SR)] and the newly developed index namely Combined Mangrove Recognition Index (CMRI) were performed. Accuracy assessment using Kappa statistics, revealing that CMRI produces better accuracy (73.43%) compared to other indices, followed by NDVI (56.29%) and SR (48.79%).

AB - Live imaging has become the favorite method in recent years to study the protein transport, localization and dynamics in live cells. Protein transport is extremely essential for proper function of photoreceptors. Aberration in the proper transport of proteins gives rise to the loss of photoreceptor and blindness. On the other hand, the ease of generation of transgenic Xenopus laevis tadpoles and the advantage of high resolution live confocal imaging provide new insight into understanding protein dynamics in photoreceptors. There are several steps for quantifying and visualizing fluorescently tagged proteins in photoreceptors starting with assembly of plasmids, generation of transgenic tadpoles, preparation of retinal tissues, imaging the transgenic photoreceptors and finally analyzing the recorded data. The focus of this manuscript is to describe how to prepare retinal tissues suited for live cell imaging and provide our readers with a tutorial video. We also give a summary of steps leading to a successful experiment that might be designed for imaging the ultrastructures of photoreceptors, the expression of two or more different fluorescently tagged proteins, their localization, distribution, or protein dynamics within photoreceptors. *Retinal tissue live imaging demonstrates the ultrastructures of photoreceptors.*High resolution live confocal imaging provides new insight into understanding the pathophysiology of photoreceptors. PMID- 30302321 TI - Adsorptive removal of noxious cadmium from aqueous solutions using poly urea formaldehyde: A novel polymer adsorbent. AB - Cadmium is a heavy metal toxic that enters water resources through industrial, household, agricultural waste and non-sanitary landfill of urban and industrial wastes. Pollution of water resources by cadmium increases incidence of diseases including Itai-Itai, kidney disorders, cancer, chromosome effects and kidney tubular damages in low exposures. The aim of this study is to study the efficiency of a new poly urea-formaldehyde adsorbent in the removal cadmium ions from aqueous solutions. The effect of different variables such as initial pH, contact time, initial concentration of cadmium and test of real wastewater samples were evaluated. In addition, laboratory data of cadmium adsorption by urea-formaldehyde adsorbent were matched to Langmuir, Freundlich and Temkin isotherm models. The results of the study showed that maximum adsorption capacity obtained by Langmuir model was 76.3 mg/g at pH = 5.5. Laboratory adsorption data matched mostly by Freundlich isotherm model (R2 =0.999) which indicates that adsorption of cadmium ions on heterogenic surfaces of poly urea-formaldehyde happens by chemical adsorption mechanism. Generally, the results of the study showed that new poly urea-formaldehyde adsorbent can be efficiently used to remove highly concentrated cadmium ions from aqueous solutions. PMID- 30302322 TI - Protocol for assembling micro- and nanoparticles in a viscous liquid above a vibrating plate. AB - In this protocol, we demonstrate the use of a vibrating plate to drive the assembly of micro- and nanoparticles as an approach to high-throughput, large scale directed assembly in a viscous liquid. Vibration drives the assembly of glass bead microparticles and iron oxide nanoparticles in contact with water over an area of 6400 mm2. We use a scaling analysis to show that there is a competition between acoustic radiation force and vibration-generated fluid flow in a viscous medium, which determines particle transport characteristics. For assembly in a viscous liquid, we find close agreement between the observed experimental results when compared to a numerical solution of the 2D wave equation that describes plate displacement. This model indicates that microparticles migrate along displacement gradients towards displacement anti nodes where the magnitude of displacement is maximum. We also observe that nanoparticles migrate toward displacement nodes where the magnitude of displacement is zero. *Cost-effective directed assembly technique without the need for microfabrication facilities*Large-scale assembly produces heterogeneously ordered structures on a vibrating substrate.

AB - Traditional Chinese and Korean medicine uses various manipulations on acupuncture points/acupoints that are located along imaginary lines on the surface of a human body, which are called 'meridians'. Acupuncture has been used from the ancient time till now to cure various diseases, including for the purpose of regenerative medicine. In various studies, meridians are alternatively called as Bong-Han ducts, primo vessels, or hyaluronic-acid rich ducts, while acupoints are called Bong-Han corpuscles, primo nodes, or hyaluronic-acid rich nodes. Meridians and acupuncture points form a system that is now called primo vascular system (PVS), which is claimed to contain various kinds of stem cells. The stem cell size is between 1-5 microns. The smallest is the primo microcells that have a putative role in regeneration. Other stem cells are adult pluripotent and hematopoietic stem cells that play a role in extra bone marrow hematopoiesis. The presence of PVS has been reproduced by many studies. However, the various stem cells need further studies to prove their existence and function, and harvesting PVS to isolate the stem cells might harm the health of the donor. PMID- 30302324 TI - A review of antioxidant and pharmacological properties of phenolic compounds in Acacia confusa. AB - In the present review article, the phytochemical, antioxidant and pharmacological studies are congregated and summarized concerning the current knowledge of the phenolic compounds of a traditional medical plant Acacia confusa in Taiwan. This plant is native to Taiwan and South-East Asia. It possesses major pharmacological activities, including antioxidant and radical scavenging activity, hepatoprotective effect, xanthine oxidase inhibition, semicarbazide-sensitive amine oxidase inhibition, angiotensin I converting enzyme inhibition, antihyperuricemic effect and anti-inflammatory activity. Phenolic compounds, especially flavonoids, flavonol glycoside and phenolic acid derivatives, are the main phytochemical compounds isolated from different plant parts of A. confusa. Recent interest in this species has focused on pharmacological investigations of the phytochemicals which exhibit potent antioxidant activity based on the multiple phenolic functionalities. The consequence of this review will further extend the potential applications of this plant and offer persuasive support to its future use in the fields of clinical medicine and health functional food. PMID- 30302325 TI - Herbal beverages: Bioactive compounds and their role in disease risk reduction - A review. AB - There is a renewed interest in non-nutritive bioactive compounds of foods and beverages as 'lifespan nutrients' in the risk reduction of non-communicable diseases. Herbal beverages, consumed as part of a balanced diet, may improve the antioxidant status and enhance the overall health status. Herbal teas/beverages are rich sources of natural bioactive compounds such as carotenoids, phenolic acids, flavonoids, coumarins, alkaloids, polyacetylenes, saponins and terpenoids, among others. A wealth of available scientific evidence demonstrates that natural bioactive compounds render a number of diversified biological effects, such as antioxidant, antibacterial, antiviral, antiinflammatory, antiallergic, antithrombotic and vasodilatory actions, as well as antimutagenicity, anticarcinogenicity and antiaging effects. A number of herbal beverages are consumed globally and some beverages have gained more popularity than others depending on their geographical origin. However, in the era of globalization, ethnic barriers have gradually been removed and such commodities although from different areas, are now universally available as international health-pro products. PMID- 30302326 TI - In vitro studies of the anticancer action of Tectaria cicutaria in human cancer cell lines: G0/G1 p53-associated cell cycle arrest-Part I. AB - Objective: The rhizome of Tectaria cicutaria has been used in Indian traditional medicine for the treatment of various disorders. The objective of present investigation is to screen various extracts of the rhizomes of Tectaria cicutaria for anti-cancer activity and to investigate the mechanism involved. Materials and methods: The rhizomes of Tectaria cicutaria were extracted with different solvents. In vitro anti-cancer activity of different rhizome extracts were studied in Human cancer Cell Lines using Sulphorodamine B (SRB) colorimetric cytotoxicity assay. The effect of ethanolic extract (TCe) on cell growth inhibition, modulation in gene expression, and induction of apoptosis using the K562 human leukemia cell line were studied. The extract was analyzed by GC-MS to identify their major chemical compounds. Results: TCe shows antioxidant potential in both DPPH scavenging assay and reducing capacity. Flow cytometric analysis showed that 11 MUg/ml of TCe arrested cell cycle progression at the G0/G1 phase. In the TCe treated K562 cells, the mRNA and protein expression level of p53 was strongly up-regulated in reverse transcription polymerase chain reaction. Furthermore, its downstream target p21 level was also increased. The GC-MS study has depicted results with the presence of twelve different compounds which will require significant further efforts for structure and putative identification. Conclusion: The present work has for the first time, tried to elucidate the anti leukemic potential of Tectaria cicutaria. TCe was more potent in K562 cells, altering the cell cycle progression and inducing apoptosis. PMID- 30302327 TI - Rosemary leaves extract: Anti-snake action against Egyptian Cerastes cerastes venom. AB - The morbidity caused by viper bites is very dangerous and the anti-venom therapy couldn't treat the local injures such as hemorrhage, edema, necrosis and inflammation of bitten tissues. Searching for safe and effective anti-venom compounds from natural sources is very important. This study was designed to explore the neutralizing ability of Rosmarinus officinalis L. leaves aqueous extract (RMAE) against Egyptian Cerastes cerastes (Cc) viper venom toxicity. The RMAE contained a considerable amount of phenolic and flavonoid contents with 3,300 and 800 mg/100 g dry weight, respectively. The RMAE showed a considerable variation of phenolic acids by using HPLC technique. Rosmarinic acid is the major component of the RMAE which recorded 400 mg/100 g dry weight and 64% of all the identified compounds. In vitro, the RMAE neutralized the enzymatic activities of proteases, l-amino acid oxidases, and phospholipases A2 of the Cc venom dose dependently. In addition, the RMAE effectively neutralized the gelatinolytic, fibrinogenolytic, hemolytic and procoagulant activities of Cc venom. In vivo, the RMAE markedly reduced lethality, hemorrhage, edema, muscle and liver toxicities induced by Cc venom. In conclusion, the venom neutralizing property of the RMAE gives a new prospect for efficient treatment of the lethal viper bites. PMID- 30302328 TI - Extraction, isolation and identification of flavonoid from Chenopodium album aerial parts. AB - Chenopodium album L., (C. album) (family: Chenopodiaceae) is an annual shrub widely grown in Asia, Africa, Europe and North America. It is commonly known as Bathua (in Hindi), pigweed, fat hen or lamb-quarters. The leaves of C. album are applied as a poultice to bug bites, sunstroke, rheumatic joints and as mild laxative. The flavonoids contained in C. album aerial parts were extracted, identified and characterized. Sequential soxhlet extraction was subjected to preliminary phytochemical screening and flavonoid quantification. The results showed that maximum yield of the flavonoid (7.335 mg/g) were obtained from acetone extract. This acetone extract was subjected to flash chromatography for isolation of flavonoid. Characterization of isolated flavonoid was done by UV, IR, 1H & 13C NMR and MS. On the basis of chemical and spectral analysis structure was elucidated as 2-(3, 4-dihydroxyphenyl)-3, 5, 7-trihydroxy-4H-chromen-4-one, a flavonoid. PMID- 30302329 TI - Chemical composition, antioxidant potential, macromolecule damage and neuroprotective activity of Convolvulus pluricaulis. AB - Herbal medicines are known to mitigate radical induced cell damage. Hence identification and scientific validation of herbal medicines contribute to better use in Ayurvedic/Unani research. In the present study, we investigated antioxidant and anti-apoptotic properties of Convolvulus pluricaulis (C. pluricaulis). C. pluricaulis exhibited antioxidant potential evident by free radical scavenging activities. C. pluricaulis pretreatment inhibited H2O2 induced macromolecule damage such as plasmid DNA damage and AAPH induced oxidation of bovine serum albumin and lipid peroxidation of rat hepatic tissues. Further to identify the neuroprotective properties of C. pluricaulis, SHSY5Y cells were treated with H2O2 with or without pretreatment of C. pluricaulis. The C. pluricaulis pretreatment at 50 MUg/ml dose exhibited 50% cell survival against 100 MUM H2O2 challenge for 24 h and it also decreased the lactate dehydrogenase leakage. Further C. pluricaulis pretreatment restored and regulated the antioxidant and apoptosis markers such as SOD, CAT, p53, and caspase-3 and inhibited, reactive oxygen species generation and depolarization of the mitochondrial membrane. C. pluricaulis possess a high content of flavonoids and polyphenols and GC-MS and FTIR analysis showed a wide variety of compounds which may contribute to the observed effects. PMID- 30302330 TI - Anti-inflammatory and preventive activity of white mulberry root bark extract in an experimental model of pancreatitis. AB - Pancreatitis is characterized by highly morbid inflammation in the pancreas. Currently, there is no specific drug available for pancreatitis except supportive medicines. The present study assessed the pancreato-protective effect of Morus alba root bark extract by using alcohol and cerulein-induced model of pancreatitis. The study also investigated the phytochemical profile through GC-MS and HPLC. Methanolic extract of Morus alba root bark extract (MEMARB) was subjected to GC-MS and HPLC studies. Male albino Wistar rats were administered ethanol (0%-36%) and cerulein (20 MUg/kg b.wt. i.p.) with or without MEMARB. Serum lipase, amylase, caspase-1, lipid peroxidation products, glutathione and enzymatic antioxidants were determined. Histological changes in the pancreas were assessed. Cudraflavone B in MEMARB was quantified by HPLC. Significant amount of Cudraflavone B was detected by quantitative HPLC. Marked increase in the levels of serum amylase, lipase, caspase-1, IL-18 and IL-1beta were observed in ethanol and cerulein administered rats than in MEMARB co-administered rats. In MEMARB co administered rats, the antioxidant status was restored to near normal levels. Histological examinations showed that MEMARB significantly reduced the inflammatory and fibrotic changes. The results reveal the potent pancreato protective effects of Morus alba root bark. The anti-inflammatory effect of Morus alba root bark extract might be due to the presence of various phytonutrients including Cudraflavone B. PMID- 30302331 TI - Preliminary clinical assessment and non- toxicity evaluation of an ayurvedic formulation BGR-34 in NIDDM. AB - In view of the overall health impact of NIDDM, inventers understand the necessity of improving glycemic control in adults with type 2 diabetes. BGR-34 provides an effective treatment option for adults with type 2 diabetes who have been inadequately controlled on lifestyle with or without other oral hypoglycemic agents (OHGAs) such as metformin, sulfonylurea, or a glitazones. BGR-34 is an appropriate option to consider for addition to a managed care drug formulary. Treatment with BGR-34 produced clinically relevant and statistically significant reductions in all three key measures of glucose control studied -FPG, PPBG and HbA1c- when compared with placebo. BGR-34, showed the promising result with respect to glycemic parameters in NIDDM patient with a significant reduction in fasting blood sugar by 34.3%, postprandial blood sugar 35.5% & glycosylated haemoglobin by 20.31% as compared to placebo group showing a reduction by 13.2%, 10.9% & 10.87% respectively. The trial has also been registered to CTRI, India. This study has been registered in the clinical trial registry-India. PMID- 30302332 TI - Relaxant effects of Azadirachta indica A. Juss var. siamensis Valeton flower extract on isolated rat ileum contractions and the mechanisms of action. AB - Azadirachta indica A. Juss var. siamensis Valeton or commonly known as Siamese neem is one of the most well-known plant in traditional Ayurvedic medicine. The aim of the present study was to investigate the relaxant effects of A. indica on isolated rat ileum contractions and its potential underlying mechanisms involved. The isometric contractions of ileum segments were investigated in organ baths for spontaneous activity and response to aqueous extract of Siamese neem flower (SNF). The spasmolytic action of the extract was also assessed on contraction induced by acetylcholine and high potassium. Our findings indicate that cumulative concentrations of SNF aqueous extract induced relaxant effect on spontaneous rat ileum contractions. The extract has also suppressed the cumulative concentration response curve for acetylcholine and pottasium ions induced contraction. The presence and absence of propranol (antagonist of beta adrenergic receptor) and l-Name (antagonist of nitric oxide synthase) in SNF aqeous extract co-treatment demonstrated no significant different in term of contraction activity when compared to SNF extract treatment alone. The treatment of SNF extract caused a significant inhibition in tissue contraction stimulated by accumulation of calcium ions. Our results showed the relaxant effect of SNF aqueous extract on the isolated rat ileum. In short, the SNF aqueous extract exhibited an inhibitory effect on the spontaneous ileum contactions particularly on the contraction stimulated by acetylcholine and high potassium. The observed effect might acted through the modulation of calcium channels. This findings provide a pharmacological basis for the traditional use of SNF for the treatment of gastrointestinal spasms. PMID- 30302333 TI - F eNO-based asthma management results in faster improvement of airway hyperresponsiveness. AB - Asthma is characterised by inflammation and respiratory symptoms. Current asthma treatment is based on severity of asthma symptoms only. Exhaled nitric oxide fraction (F eNO) is not recommended by the Global Initiative for Asthma guidelines. The aim was to compare the usefulness of a F eNO guided versus symptom-based treatment in achieving improved asthma control assessed by airway hyperresponsiveness (AHR). 80 asthmatic patients were included in a double blinded, parallel, randomised controlled trial with follow-up visits after 8, 24 and 36 weeks. Treatment was tailored using either a F eNO or Asthma Control Questionnaire (ACQ) based algorithm. Inclusion criteria were asthma symptoms and a provocative dose causing a 15% fall in forced expiratory volume in 1 s <635 mg mannitol. At each visit AHR, F eNO, ACQ and blood tests were performed. No differences between the two groups were found at inclusion. AHR from 8 to 24 weeks was improved in the F eNO group compared to the ACQ group (response dose ratio (RDR) geometric mean (95% CI): 0.02 (0.01-0.04) versus 0.05 (0.03-0.07), respectively, p=0.015). AHR to mannitol at 36 weeks showed no differences between the two groups (mean difference RDR (95% CI): -0.02 (-0.05-0.02), p=0.3). Total doses of inhaled steroid and number of exacerbations were similar (p>0.05). When using F eNO as a treatment management tool, lowering of airway responsiveness occurred earlier than using ACQ. However, airway responsiveness and asthma control after 9 months were similar. PMID- 30302334 TI - Hypersensitivity pneumonitis in fish processing workers diagnosed by inhalation challenge.

AB - Clinically important deterioration (CID) is a novel composite end-point (lung function, health status, exacerbations) for assessing disease stability in patients with chronic obstructive pulmonary disease (COPD). We prospectively analysed CID in the FULFIL study. FULFIL (ClinicalTrials.gov NCT02345161; randomised, double-blind, double-dummy, multicentre study) compared 24 weeks of once daily, single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) 100/62.5/25 ug with twice daily budesonide/formoterol (BUD/FOR) 400/12 MUg in patients aged >=40 years with symptomatic advanced COPD (Global Initiative for Chronic Obstructive Lung Disease group D). A subset of patients received study treatment for up to 52 weeks. Time to first CID event was assessed over 24 and 52 weeks using two approaches for the health status component: St George's Respiratory Questionnaire and COPD assessment test. FF/UMEC/VI significantly reduced the risk of a first CID event by 47-52% versus BUD/FOR in the 24- and 52-week populations using both CID definitions (p<0.001). The median time to first CID event was >=169 days and <=31 days with FF/UMEC/VI and BUD/FOR, respectively. Only stable patients with no CID at 24 weeks demonstrated sustained clinically important improvements in lung function and health status at 52 weeks versus those who had experienced CID. Once daily, single-inhaler FF/UMEC/VI significantly reduced the risk of CID versus twice daily BUD/FOR with a five-fold longer period without deterioration.

AB - Background: To evaluate the treatment outcomes of patients with punctate inner choroidopathy (PIC) and secondary choroidal neovascularization (CNV). Methods: This is a retrospective study of 24 eyes in 22 patients suffering from PIC with CNV. Patients were treated with intravitreal ranibizumab monotherapy (14 eyes) or combined oral corticosteroid and intravitreal ranibizumab therapy (corticosteroid ranibizumab group, 10 eyes). Mean follow-up duration was 24.0 months. We evaluated best-corrected visual acuity (BCVA), fundus autofluorescence, fluorescein angiography, indocyanine green angiography, and optical coherence tomography, before and after treatment. The following variables were compared between groups: number of intravitreal ranibizumab injections, BCVA, recurrence of CNV, and change in PIC lesions. Results: The ranibizumab monotherapy group received an average of 3 intravitreal ranibizumab injections; mean logMAR visual acuity improvement was 0.34, and 8 eyes developed recurrent CNV during follow-up. The corticosteroid-ranibizumab group received an average of 1.9 intravitreal ranibizumab injections; mean logMAR visual acuity improvement was 0.61, and there was no recurrence of CNV. Combined corticosteroid-ranibizumab therapy also resulted in better resolution of PIC lesions and fewer new PIC lesions. Conclusion: Both corticosteroid-ranibizumab treatment and ranibizumab monotherapy could significantly improve the vision of PIC patients with CNV. Combined corticosteroid and intravitreal ranibizumab treatment appeared to reduce CNV recurrence and development of new PIC lesions compared with ranibizumab monotherapy.

AB - Stereology is a quantitative and comparative method that utilizes planes, lines, and points for the estimation of three-dimensional parameters in morphological studies. It primarily focuses on geometrical features of objects such as number, density, length, area, and volume. A scientometric study was conducted to analyze global research trends in application of stereology in biomedical research. Stereology has gained wide application resulting into design-based stereological methods. Data for this study were retrieved from the SCOPUS database. At least 5,732 publications employing stereology as analytical tool were produced in a period of 50 years between 1966 and 2016. Half (2,858; 49.87%) of these publications were produced in the last 12 years from 2005 to 2016. The relative growth rate (RGR) of publications decreased from 1967 (0.69) to 2016 (0.03) whereas the doubling time (DT) increased from 1.00 to 20.56 in the same period. A great majority (5,332; 93.02%) of the publications retrieved from SCOPUS were journal articles in various biomedical fields. The Journal of Microscopy tops the list of journals with at least 205 articles. The most productive country was USA with at least 1663 (23.10%) publications and Aarhus Universitet tops the list of institutions with at least 306 publications. J.R. Nyengaard was the most prolific author who contributed at least 125 publications. The highly cited article had a total of 2,054 citations with an average of over 82 citations per year. Given the growing importance of stereology in biomedical research, it is necessary to promote its application among scholars. PMID- 30302339 TI - Mummification in Korea and China: Mawangdui, Song, Ming and Joseon Dynasty Mummies. AB - Over the decades, mummy studies have expanded to reconstruct a multifaceted knowledge about the ancient populations' living conditions, pathologies, and possible cause of death in different spatiotemporal contexts. Mainly due to linguistic barriers, however, the international knowledge of East Asian mummies has remained sketchy until recently. We thus analyse and summarize the outcomes of the studies so far performed in Korea and China in order to provide mummy experts with little-known data on East Asian mummies. In this report, similarities and differences in the mummification processes and funerary rituals in Korea and China are highlighted. Although the historical periods, the region of excavation, and the structures of the graves differ, the cultural aspects, the mechanisms of mummification, and biological evidence appear to be essentially similar to each other. Independently from the way they are called locally, the Korean and Chinese mummies belong to the same group with a shared cultural background. PMID- 30302340 TI - Endowing iPSC-Derived MSCs with Angiogenic and Keratinogenic Differentiation Potential: A Promising Cell Source for Skin Tissue Engineering. AB - Induced pluripotent stem cells (iPSC) hold tremendous potential for personalized cell-based therapy for skin regeneration. Aiming to establish human iPSCs as a potential cell source for skin tissue engineering, we expect to obtain an epidermal-like cell line with angiogenic and keratinogenic differentiation potential via inducing iPSC-derived mesenchymal stem cells (iPSC-MSCs) with basic fibroblast growth factor (bFGF) and/or keratinocyte growth factor (KGF). The results show that iPSC-MSCs were successfully induced with a positive FGFR/KGFR expression on the cell surface. BFGF/KGF induction could significantly increase the expression of vascularization marker CD31 and keratinization marker CK10, respectively, while when combined together, although CD31 and CK10 were still positively expressed, their expressions were lower than that of the single induction group, suggesting that the effects of the two growth factors interfered with each other. This cell line with angiogenic and keratinogenic differentiation potential provides a promising new source of cells for the construction of well vascularized and keratinized tissue engineered skin, furthermore establishing an effective strategy for iPSC-based therapy in skin tissue engineering. PMID- 30302341 TI - Protocol for Fecal Microbiota Transplantation in Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis. AB - Background: Fecal microbiota transplantation (FMT) is an emerging treatment approach for inflammatory bowel disease (IBD). The donor selection, the separation of fecal bacteria, the frequency of FMT, the way of infusion, the long term safety, and efficacy are still uncertain. Aim: To further study the efficacy and safety and protocol of FMT for IBD. Methods: A systematic review and meta analysis were conducted until February, 2018. Clinical remission was established as the primary outcome. Results: A total of 596 paediatric and adult IBD patients were enrolled, and 459 patients received FMT therapy. 28.8% (132/459) patients achieved clinical remission during follow-up. 53% (241/459) patients achieved clinical response. The pooled estimated clinical remission for ulcerative colitis (UC) was 21% (95% CI: 8%-37%) and 30% (95% CI: 11%-52%) for Crohn's disease (CD), both with a risk of heterogeneity; 10% (95% CI: 0%-43%) for paediatric UC; 26% (95% CI: 10%-48%) for adult UC; 45% for paediatric CD (95% CI: 24%-66%); 22% (95% CI: 3%-52%) for adult CD. Meta-analysis of cohort studies showed that moderate severe IBD patients could achieve more significant remission from FMT than mild moderate patients (P=0.037). Delivery route has no impact on the efficacy of FMT in UC and CD. Based on current available evidence, a trend was observed towards higher clinical remission rate of frozen stool FMT than that of fresh stool for UC, while there was no significant difference between fresh and frozen FMT for CD. The optimal donor stool for FMT is still uncertain. Meta-analysis of RCTs showed that FMT treatment achieved significantly higher clinical remission rate than placebo for UC (28% versus 9%, P=0.0003). Conclusion: FMT is an effective and safe therapy for both paediatric and adult IBD; fresh or frozen donor stool, delivery route, and antibiotic pretreatment or not have no impact on the efficacy of FMT in IBD. FMT might be a potential rescue therapy and even an initial standardized therapy for IBD. However, few data exist on long-term safety and efficacy and further validation is needed. PMID- 30302338 TI - Social Cognition through the Lens of Cognitive and Clinical Neuroscience. AB - Social cognition refers to a set of processes, ranging from perception to decision-making, underlying the ability to decode others' intentions and behaviors to plan actions fitting with social and moral, besides individual and economic considerations. Its centrality in everyday life reflects the neural complexity of social processing and the ubiquity of social cognitive deficits in different pathological conditions. Social cognitive processes can be clustered in three domains associated with (a) perceptual processing of social information such as faces and emotional expressions (social perception), (b) grasping others' cognitive or affective states (social understanding), and (c) planning behaviors taking into consideration others', in addition to one's own, goals (social decision-making). We review these domains from the lens of cognitive neuroscience, i.e., in terms of the brain areas mediating the role of such processes in the ability to make sense of others' behavior and plan socially appropriate actions. The increasing evidence on the "social brain" obtained from healthy young individuals nowadays constitutes the baseline for detecting changes in social cognitive skills associated with physiological aging or pathological conditions. In the latter case, impairments in one or more of the abovementioned domains represent a prominent concern, or even a core facet, of neurological (e.g., acquired brain injury or neurodegenerative diseases), psychiatric (e.g., schizophrenia), and developmental (e.g., autism) disorders. To pave the way for the other papers of this issue, addressing the social cognitive deficits associated with severe acquired brain injury, we will briefly discuss the available evidence on the status of social cognition in normal aging and its breakdown in neurodegenerative disorders. Although the assessment and treatment of such impairments is a relatively novel sector in neurorehabilitation, the evidence summarized here strongly suggests that the development of remediation procedures for social cognitive skills will represent a future field of translational research in clinical neuroscience. PMID- 30302343 TI - Diabetes and Associated Cardiovascular Complications in American Indians/Alaskan Natives: A Review of Risks and Prevention Strategies. AB - : Diabetes mellitus (DM) is the seventh leading cause of death in the United States and the leading cause of death in the U.S. American Indian/Alaskan Natives (AI/ANs), who comprise only 2% of the total population. The AI/AN population has a high prevalence of DM in adults aged 20 years or older and is developing DM at a younger age than the general U.S. POPULATION: DM is a major risk factor for cardiovascular disease (CVD), and mortality from CVD is higher in AI/ANs than the general population, as is the prevalence of stroke and 1-year poststroke mortality for both genders when compared to non-Hispanic whites. A genome-wide scan found a number of chromosome linkages in the AI/AN population that suggest that genetic factors may contribute to their high risk of DM and CVD. Importantly, studies also suggest that in addition to race/ethnicity, cultural norms and historic conditions play important roles in the prevalence of DM and CVD in this population. Therefore, multiple factors should be taken into consideration when establishing prevention programs to decrease the prevalence of obesity, diabetes, and CVD incidence among adults and children in the AI/AN population. Prevention programs should focus on behavioral risk factors and lifestyle changes like encouraging smoking cessation, healthy diet, and increased physical activity while taking into consideration cultural, economic, and geographic factors. PMID- 30302342 TI - Frailty and Exercise Training: How to Provide Best Care after Cardiac Surgery or Intervention for Elder Patients with Valvular Heart Disease. AB - The aim of this literature review was to evaluate existing evidence on exercise based cardiac rehabilitation (CR) as a treatment option for elderly frail patients with valvular heart disease (VHD). Pubmed database was searched for articles between 1980 and January 2018. From 2623 articles screened, 61 on frailty and VHD and 12 on exercise-based training for patients with VHD were included in the analysis. We studied and described frailty assessment in this patient population. Studies reporting results of exercise training in patients after surgical/interventional VHD treatment were analyzed regarding contents and outcomes. The tools for frailty assessment included fried phenotype frailty index and its modifications, multidimensional geriatric assessment, clinical frailty scale, 5-meter walking test, serum albumin levels, and Katz index of activities of daily living. Frailty assessment in CR settings should be based on functional, objective tests and should have similar components as tools for risk assessment (mobility, muscle mass and strength, independence in daily living, cognitive functions, nutrition, and anxiety and depression evaluation). Participating in comprehensive exercise-based CR could improve short- and long-term outcomes (better quality of life, physical and functional capacity) in frail VHD patients. Such CR program should be led by cardiologist, and its content should include (1) exercise training (endurance and strength training to improve muscle mass, strength, balance, and coordination), (2) nutrition counseling, (3) occupational therapy (to improve independency and cognitive function), (4) psychological counseling to ensure psychosocial health, and (5) social worker counseling (to improve independency). Comprehensive CR could help to prevent, restore, and reduce the severity of frailty as well as to improve outcomes for frail VHD patients after surgery or intervention. PMID- 30302345 TI - Carbamazepine-Mediated Adverse Drug Reactions: CBZ-10,11-epoxide but Not Carbamazepine Induces the Alteration of Peptides Presented by HLA-B*15:02. AB - Among patients treated with the anticonvulsive and psychotropic drug carbamazepine (CBZ), approximately 10% develop severe and life-threatening adverse drug reactions. These immunological conditions are resolved upon withdrawal of the medicament, suggesting that the drug does not manifest in the body in long term. The HLA allele B*15:02 has been described to be a genomic biomarker for CBZ-mediated immune reactions. It is not well understood if the immune reactions are triggered by the original drug or by its metabolite carbamazepine-10,11-epoxide (EPX) and how the interaction between the drug and the distinct HLA molecule occurs. Genetically engineered human B-lymphoblastoid cells expressing soluble HLA-B*15:02 molecules were treated with the drug or its metabolite. Functional pHLA complexes were purified; peptides were eluted and sequenced. Applying mass spectrometric analysis, CBZ and EPX were monitored by analyzing the heavy chain and peptide fractions separately for the presence of the drug. This method enabled the detection of the drug in a biological situation post-pHLA assembly. Both drugs were bound to the HLA-B*15:02 heavy chain; however, solely EPX altered the peptide-binding motif of B*15:02-restricted peptides. This observation could be explained through structural insight; EPX binds to the peptide-binding region and alters the biochemical features of the F pocket and thus the peptide motif. Understanding the nature of immunogenic interactions between CBZ and EPX with the HLA immune complex will guide towards effective and safe medications. PMID- 30302344 TI - Cancer Immunotherapy: Priming the Host Immune Response with Live Attenuated Salmonella enterica. AB - In recent years, cancer immunotherapy has undergone great advances because of our understanding of the immune response and the mechanisms through which tumor cells evade it. A century after the first immunotherapy attempt based on bacterial products described by William Coley, the use of live attenuated bacterial vectors has become a promising alternative in the fight against cancer. This review describes the role of live attenuated Salmonella enterica as an oncolytic and immunotherapeutic agent, due to its high affinity for tumor tissue and its ability to activate innate and adaptive antitumor immune response. Furthermore, its potential use as delivery system of tumor antigens and immunomodulatory molecules that induce tumor regression is also reviewed. PMID- 30302346 TI - An Esophagogram or Tracheobronchogram? A Review of Barium Sulfate Aspiration. AB - The barium swallow is an important radiological investigation used for the diagnosis of upper gastrointestinal anatomical disorders like esophageal cancer, diverticulum, achalasia, foreign body, among others. Generally, it is believed to be a safe technique with rare complications, but few cases of barium sulfate aspiration have been reported in the literature with multiple complications. We are reporting a case of an elderly male who underwent esophagogram for the workup of chronic dysphagia, aspirated barium sulfate, and went into respiratory failure and circulatory shock several hours later. Moreover, we also did a systematic literature search and reviewed all available articles on aspiration of barium sulfate and its potential complications. We focused on predisposing factors for aspiration, clinical presentation, complications after aspiration, and prognosis with the aim to better understand and manage this condition. PMID- 30302347 TI - Effect of Posterior Glenoid Labral Tears at the NFL Combine on Future NFL Performance. AB - Background: Posterior labral injuries have been recognized as a particularly significant clinical problem in collision and contact athletes. Purpose: To evaluate the effect that posterior labral tears have on early National Football League (NFL) performance based on position, associated injuries, and operative versus nonoperative management. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective review of all participants in the NFL Combine from 2009 to 2015 was performed using medical and imaging reports documented at the combine. Magnetic resonance imaging scans were analyzed for tear location, associated injuries, and evidence of previous surgical interventions. Each player's NFL draft position, as well as number of games played, number of games started, and snap percentage in his first 2 NFL seasons were collected for performance analysis and were compared with a control group of uninjured counterparts. Results: Players with posterior labral tears were selected significantly later in the draft than those in the control group (draft position, 171.6 vs 156.1, respectively; P = .017). Although no single individual position was significantly affected by posterior labral tears, linemen (both offensive and defensive) with posterior labral tears were drafted significantly later than those without tears (draft position, 164.0 vs 137.7, respectively; P = .018) and had a significantly lower percentage of snaps in their first NFL season (23.8% vs 27.7%, respectively; P = .014). Players who underwent surgical management before the combine had a significantly higher percentage of snaps in their second NFL season than those who were managed conservatively (31.4% vs 22.3%, respectively; P = .022). None of the concomitant injuries recorded (superior labral anterior posterior tears, glenoid bone loss, reverse Hill-Sachs lesions, rotator cuff tears, reverse humeral avulsions of the glenohumeral ligament, and posterior labral tears combined with anterior tears) significantly affected the draft position, number of games played, number of games started, or snap percentage for the cohort as a whole or any specific position. Conclusion: Posterior labral tears did negatively and significantly affect early NFL outcomes for collegiate football players across several different metrics, especially among linemen. While operative management did not produce significantly superior performance in most outcome measures, it may allow for better longevity of the shoulder and warrants further investigation. Concomitant shoulder injuries did not significantly affect early NFL outcomes in this cohort. PMID- 30302348 TI - The Rapidly Assessed Predictor of Intraoperative Damage (RAPID) Score: An In Clinic Predictive Model for High-Grade Acetabular Chondrolabral Disruption. AB - Background: The preoperative assessment of cartilage lesions is critical to surgical planning and decision making. The accurate radiographic determination of acetabular cartilage damage has remained elusive for modern imaging modalities, including magnetic resonance imaging (MRI) and magnetic resonance arthrography (MRA). While risk factors have been individually described, no multivariable system exists for predicting high-grade cartilage damage. Purpose: To determine the preoperative predictors of grade 3 to 4 acetabular labrum articular disruption (ALAD) lesions. Study Design: Case-control study; Level of evidence, 3. Cohort study (diagnosis); Level of evidence, 1. Methods: Retrievable radiographs were reviewed from primary hip arthroscopic procedures performed at 2 high-volume institutions between December 2007 and April 2017. The predictive value of demographic and radiographic factors for the intraoperative documentation of ALAD grade 3 to 4 damage was analyzed and entered into a multivariable model, and a statistically guided scoring system for the damage risk was created using the Akaike information criterion. The scoring system was then prospectively validated on 167 patients who underwent primary hip arthroscopy between April 2017 and February 2018. Results: A total of 652 primary hip arthroscopic procedures in 614 patients (390 female, 224 male; mean age, 33.2 +/- 12.5 years; mean body mass index, 26.9 +/- 5.5 kg/m2) from 2007 to 2017 were analyzed. Male sex (odds ratio [OR], 3.11; P < .01), age >=35 years (OR, 1.96; P < .01), cam morphology (alpha angle >55 degrees ) (OR, 2.96; P < .01), and Tonnis grade 1 to 2 (grade 1: OR, 4.14; P < .01, and grade 2: OR, 9.29; P < .01) were univariate risk factors for intraoperatively documented high-grade damage. A multivariable scoring system, the Rapidly Assessed Predictor of Intraoperative Damage (RAPID) score (0-5 points), was generated based on sex, Tonnis grade, and cam morphology. Patients with increasing RAPID scores had an increasing risk of damage, with a 10.5% risk for those with 0 points and an 88.0% risk for those with 5 points (P < .01). The area under the curve was 0.75 for the study group and 0.76 for the validation group (P = .94). Conclusion: While preoperative MRI has diagnostic value for hip arthroscopic surgery, the RAPID score provides added benefit as a readily employable, in-clinic system for predicting high-grade cartilage damage. The discriminatory value of the RAPID score compares favorably with previous MRI and MRA studies. This information will help the clinician and patient plan for high-grade damage and identify potential targets for cartilage treatment. PMID- 30302349 TI - Diagnostic Accuracy of the Scapular Retraction Test in Assessing the Status of the Rotator Cuff. AB - Background: Currently, clinical physical examination maneuvers alone provide variable reliability in diagnosing full-thickness rotator cuff tears (RCTs). Purpose: To assess the diagnostic accuracy of the scapular retraction test (SRT) to predict full-thickness RCTs. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: A total of 331 patients were prospectively evaluated in this cohort study. SRT was performed to assess the status of the rotator cuff. A positive SRT indicates an intact rotator cuff, and a negative SRT indicates a full-thickness RCT. Magnetic resonance imaging (MRI) was used as the gold standard. The examiner was blinded to the results until completing the physical examination. Statistical analysis was performed to assess the sensitivity, specificity, accuracy, positive and negative predictive values, and positive and negative likelihood ratios of the SRT. Results: The prevalence of full-thickness RCTs diagnosed on MRI was 54.4% (180 of 331). Among the 180 patients with an MRI confirmed full-thickness RCT, the SRT was negative for 147. Of 150 patients with an intact rotator cuff by MRI, 122 had a positive SRT. In diagnosing full thickness RCTs, the SRT had a sensitivity of 81.7% (95% CI, 77.2%-85.4%), specificity of 80.8% (95% CI, 75.5%-85.3%), and accuracy 81.3%. The positive predictive value was 83.5% (95% CI, 78.9%-87.4%); the negative predictive value, 78.7% (95% CI, 73.5%-83.1%); the positive likelihood ratio, 4.3 (95% CI, 3.1 5.8); the negative likelihood ratio, 0.23 (95% CI, 0.17-0.30); and the diagnostic odds ratio, 18.7 (95% CI, 10.4-34.0). Conclusion: The results of this diagnostic study indicate that the SRT can accurately be used to clinically assess the status of the rotator cuff. This physical examination maneuver was found to be accurate, sensitive, and specific in diagnosing full-thickness RCTs. Additionally, our results indicate that it is equally as accurate to predict an intact rotator cuff tendon. Providing an accurate, reliable, and reproducible physical examination test will allow clinicians to diagnosis the integrity of the rotator cuff and will help guide treatment recommendations. PMID- 30302350 TI - Cost of Public Health Response and Outbreak Control With a Third Dose of Measles Mumps-Rubella Vaccine During a University Mumps Outbreak-Iowa, 2015-2016. AB - Background: The United States is experiencing mumps outbreaks in settings with high 2-dose measles-mumps-rubella (MMR) vaccine coverage, mainly universities. The economic impact of mumps outbreaks on public health systems is largely unknown. During a 2015-2016 mumps outbreak at the University of Iowa, we estimated the cost of public health response that included a third dose of MMR vaccine. Methods: Data on activities performed, personnel hours spent, MMR vaccine doses administered, miles traveled, hourly earnings, and unitary costs were collected using a customized data tool. These data were then used to calculate associated costs. Results: Approximately 6300 hours of personnel time were required from state and local public health institutions and the university, including for vaccination and laboratory work. Among activities demanding time were case/contact investigation (36%), response planning/coordination (20%), and specimen testing and report preparation (13% each). A total of 4736 MMR doses were administered and 1920 miles traveled. The total cost was >$649 000, roughly equally distributed between standard outbreak control activities and third-dose MMR vaccination (55% and 45%, respectively). Conclusions: Public health response to the mumps outbreak at the University of Iowa required important amounts of personnel time and other resources. Associated costs were sizable enough to affect other public health activities. PMID- 30302351 TI - Epidemiology of Carbapenem-Resistant Enterobacteriaceae at a Long-term Acute Care Hospital. AB - Background: Residents of long-term acute care hospitals (LTACHs) are considered important reservoirs of multidrug-resistant organisms, including Carbapenem resistant Enterobacteriaceae (CRE). We conducted this study to define the characteristics of CRE-infected/colonized patients admitted to an LTACH and the molecular characteristics of the CRE isolates. Methods: This retrospective study was conducted to collect information on demographic and comorbid conditions in CRE-colonized/infected patients admitted to a 77-bed LTACH in Detroit between January 2011 and July 2012. Data pertaining to hospital-related exposures were collected for 30 days before positive CRE culture. Polymerase chain reaction (PCR) gene amplification, repetitive sequence-based PCR, and multilocus sequence typing (MLST) were performed on 8 of the CRE isolates. Results: The study cohort included 30 patients with CRE-positive cultures, 24 (80%) with infections, and 6 (20%) with colonization. The mean age of cohort was 69 +/-12.41 years; 19 (63%) patients were ventilator-dependent, and 20 (67%) were treated with at least 1 antibiotic. Twenty-three (77%) patients had CRE detected following LTACH admission, and the median days from admission to CRE detection in these patients (interquartile range) was 25 (11-43). Seven more patients were already positive for CRE at the time of LTACH admission. Molecular genotyping and MLST of 8 CRE isolates demonstrated that all isolates belonged to the same strain type (ST258) and contained the bla KPC-3 sequence. Conclusions: The majority of patients with CRE presented several days to weeks after LTACH admission, indicating possible organism acquisition in the LTACH itself. The genetic similarity of the CRE isolates tested could further indicate the occurrence of horizontal transmission in the LTACH or simply be representative of the regionally dominant strain. PMID- 30302352 TI - Real-World Experience With Higher-Than-Recommended Doses of Lamivudine in Patients With Varying Degrees of Renal Impairment. AB - Background: Although nucleoside reverse transcriptase inhibitors have been associated with lactic acidosis, lamivudine (3TC) has not been reported to have an increased risk with elevated concentrations. Therefore, some recommend that the lowest tablet strength of 3TC be considered in patients with kidney disease to avoid the inconvenience of liquid formations. Our institution avoids dose adjusting 3TC until creatinine clearance (CrCl) <30 mL/min and uses 100-150-mg tablets daily in hemodialysis. The aim of this study was to describe the use of higher-than-recommended doses of 3TC in a real-world setting. Methods: Blood samples were collected before and 0.5-1.5 hours after 3TC administration in HIV+ adults. Predose (Cmin) and postdose (Cmax) samples were measured by high performance liquid chromatography. Physiologically based pharmacokinetic modeling was utilized to simulate areas under the curve (AUCs) and profiles by CrCl. Lactic acid levels and patient-reported adverse events were obtained to monitor for safety, and viral suppression was assessed for efficacy. Results: Thirty-four patients with varying degrees of renal function were enrolled. Observed 3TC Cmax values were comparable among CrCl cohorts. Simulated 3TC AUC values in patients with CrCl 30-49, 15-29, and 0-15 mL/min were consistent with historical data, and fold-errors were between 0.5 and 2.0. All lactic acid levels were within normal limits, and no adverse effects were reported. Conclusions: This study is the first to describe the use of higher-than-recommended doses of 3TC in a real-world setting. 3TC was well tolerated across all levels of renal function. These results can guide providers in their selection of higher 3TC dosing in select patients with renal dysfunction to maximize adherence. PMID- 30302353 TI - Impact of Case-Specific Education and Face-to-Face Feedback to Prescribers and Nurses in the Management of Hospitalized Patients With a Positive Clostridium difficile Test. AB - Background: Approaches to changing providers' behavior around Clostridium difficile (CD) management are needed. We hypothesized that case-specific teaching points and face-to-face discussions with prescribers and nurses would improve management of patients with a positive CD test. Methods: Charts of patients age >=18 years with positive CD tests hospitalized July 2016 to May 2017 were prospectively reviewed to assess CD practices and generate management recommendations. The study had 4 periods: baseline (pre-intervention), intervention #1, observation, and intervention #2. Both interventions consisted of an in-person, real-time, case-based discussion and education by a CD Action Team (CDAT). Assessment occurred within 24 hours of a positive CD test for all periods; during the intervention periods, management was also assessed within 48 hours after CDAT-delivered recommendations. Outcomes included proportion of patients receiving optimized treatment and incidence rate ratios of practice changes (both CDAT-prompted and CDAT-independent). Results: Overall, the CDAT made recommendations to 84 of 96 CD cases during intervention periods, and providers accepted 43% of CDAT recommendations. The implementation of the CDAT led to significant improvement in bowel movement (BM) documentation, use of proton pump inhibitors, and antibiotic selection for non-CD infections. Selection of CD-specific therapy improved only in the first intervention period. Laxative use and treatment of CD colonization cases remained unchanged. Only BM documentation, a nurse-driven task, was sustained independent of CDAT prompting. Conclusions: A behavioral approach to changing the management of positive CD tests led to self-sustained practice changes among nurses but not physicians. Better understanding of prescribers' decision-making is needed to devise enduring interventions. PMID- 30302354 TI - Entities of Chronic and Granulomatous Invasive Fungal Rhinosinusitis: Separate or Not? AB - Background: Chronic and granulomatous invasive fungal rhinosinusitis are important causes of blindness and craniocerebral complications. However, the classification of these 2 diseases remains controversial. Methods: We retrospectively analyzed patients with chronic and granulomatous invasive fungal rhinosinusitus in a Chinese tertiary hospital from 2009 to 2017, with a focus on classification and comparisons. Results: Among 55 patients enrolled in our study, 11 (11/55, 20%) had granulomatous invasive fungal rhinosinusitis (GIFRS) and 44 (44/55, 80%) had chronic invasive fungal rhinosinusitis (CIFRS). Aspergillus fumigatus and Dematiaceous hyphomycetes were identified in 2 patients with GIFRS. Compared with granulomatous type, CIFRS was more frequently encountered in immunocompromised patients (P = .022), and the time from onset to diagnosis was much shorter (P = .001). Proptosis and orbital apex syndrome showed no significant difference between granulomatous and CIFRS in our study. The treatment options and prognosis of both diseases also showed no significant difference. Conclusions: Despite the consensus on histopathology, the classification of the chronic and granulomatous types may need further evaluation in clinical considerations.

AB - This study of 64 solid organ and hematopoietic stem cell transplant recipients found that peripheral blood absolute lymphocyte count of <610 and <830/uL, respectively, correlated with cytomegalovirus infection. In an era when sophisticated measures of CMV-specific T cells are emerging, we emphasize the utility of the inexpensive and readily-available absolute lymphocyte count. PMID- 30302356 TI - Parenting Desires Among Individuals Living With Human Immunodeficiency Virus in the United States. AB - Background: In 1988, 1 of 3 women (W) and heterosexual men living with human immunodeficiency virus (HIV) reported wanting children, but little is known about parenting desires of men who have sex with men (MSM) living with HIV. We examined parenting desires among persons initiating antiretroviral therapy (ART). Methods: Of 1809 participants in the AIDS Clinical Trials Group (ACTG) Study 5257, 1425 W aged <=45 years or men completed questionnaires about parenting desires at baseline and 96 weeks after initiating ART. Self-reported desires for children in the future (yes/unsure vs no) and associations between baseline sociodemographics and parenting desires at 96 weeks were examined using multivariable logistic regression, overall and within subgroups. Results: The 1425 participants were as follows: 36% white, 39% black, 22% Hispanic; median age 36 (interquartile range, 28-44); 70% MSM, 13% men reported sex only with W (MSW), 17% W. At baseline, 42% may want children in the future (42% MSM, 37% MSW, 43% W); at 96 weeks, 41% may want children (41% MSM, 37% MSW, 43% W). At follow-up, approximately 10% of responses changed in each direction. In multivariable analyses, education greater than high school, <30 years, and having no children were significantly associated with future parenting desires among all subgroups. Among MSM, being black was associated with desiring children. Conclusions: Approximately 40% of MSM, W, and MSW with HIV may want children, both at baseline and 96 weeks after ART initiation. These results highlight the need to regularly assess parenting goals, provide access to comprehensive reproductive services, and address prevention of vertical and heterosexual HIV transmission. PMID- 30302358 TI - Data on ethyl glucuronide and cocaethylene concentrations in the hair of cocaine users. AB - We present data on ethyl glucuronide and cocaethylene concentrations from the hair of cocaine users. Head hair from 64 subjects, previously tested for cocaine, cocaethylene, benzoylecogonine and anhydroecgonine methyl ester (AEME), were subsequently analysed for Ethyl Glucuronide (EtG). Samples were prepared by solid phase extraction and analysed using gas chromatrography coupled to tandem mass spectrometry. The dataset is made available to allow analysis of possible correlation between cocaethylene and ethyl glucuronide or between other metabolites presented in the data. PMID- 30302357 TI - Identification of putative flowering genes and transcription factors from flower de novo transcriptome dataset of tuberose (Polianthes tuberosa L.). AB - Polianthes tuberosa is commercially popular because of their economic importance in floriculture for cut and loose flowers and in perfume industry because of the unique fragrance. Despite its commercial importance, no ready-to-use transcript sequence information is available in the public database. We have sequenced the RNA obtained from tuberose flowers using the Illumina HiSeq. 2000 platform and have carried out a de novo analysis of the transcriptome data. The de novo assembly generated 11,100 transcripts. These transcripts represent a total of 7876 unigenes that were considered for downstream analysis. These 7876 unigenes, which was further annotated using blast2go and KEGG pathways, were also assigned. Tuberose transcripts were also assigned to metabolic pathways using the Kyoto Encyclopedia of Genes and Genomes database to determine their biochemical functions. 4591 of the tuberose transcripts matched to genes in KEGG pathways and 66 transcripts were mapped to the Flavonoid biosynthesis pathway. 21 flowering genes have been identified in this tuberose transcriptome. Transcription factor analysis helped in the identification of a large number of transcripts similar to key genes in the flowering regulation network of Arabidopsis thaliana. Among the transcription factors identified "NAC" which is associated with plant stress response represented the most abundant category followed by APETALA2 (AP2)/ethylene-responsive element binding proteins (EREBPs) which plays various role in floral organ identity and respond to different biotic and abiotic stress.

PMID- 30302365 TI - Seroprevlance of Coxiella burnetii among abattoir and slaughterhouse workers: A meta-analysis. AB - Q fever caused by the gram negative bacteria, Coxiella burnetii, is an occupational hazard for those who live and work in rural settings and those who are in contact with animals, especially abattoir and slaughterhouse workers. Australia is the only country to register a vaccine to prevent Q fever (Q-vax(r), Seqirus, Australia) that is used in high risk populations. Seroprevalence studies conducted to determine the burden of Q fever (C. burnetii infection) in different settings have demonstrated high levels of heterogeneity with estimates of the percent positive ranging from 30% to 70%. There is a need for a more systematic evaluation of the findings of these studies in order to provide summary estimates of the seroprevalence in different settings. We searched for published articles using PubMed, MEDLINE-EMBASE, and Scopus databases using search terms obtained from an initial review of published reports of recent Q fever outbreaks. Data on the seroprevalence of C. burnetii infection (Q fever) was extracted from the selected studies and a random effects meta-analysis was performed with stratification by outbreak status, year, country and serological techniques used. Results were visualised with a forest plot with 95% CI and measures of heterogeneity (I 2) for the random effects model. A total of 19 articles that met the search criteria were included. The reported seroprevalence rate ranged from 4.7% to 91.7% among abattoir and slaughterhouse workers. No inter-group heterogeneity was observed (p = 0.956), supporting the pooling of all studies into one pooled measure. The pooled estimate of seropositivity for C. burnetii infection in people working in abattoirs and slaughterhouses was 26% (95% CI: 18 35%) regardless of the evidence of an "outbreak", the time of year or country. Seropositivity for C burnetii was independent of a person's age and years of occupational experience. Within abattoirs and slaughterhouses, slaughtering of cattle, sheep and goats are the most important risk factors associated with seropositivity and for those who showed over symptoms upon infection. We recommend that vaccination programmes are directed towards people employed in the meat processing industry to mitigate the significant health and economic impacts of Q fever. PMID- 30302366 TI - Canadian report card on health equity across the life-course: Analysis of time trends and cross-national comparisons with the United Kingdom. AB - Addressing social determinants of health (SDoH) has been acknowledged as an essential objective for the promotion of both population health and health equity. Extant literature has identified seven potential areas of investment to address SDoH: investments in sexual and reproductive health and family planning, early learning and child care, education, universal health care, as well as investments to reduce child poverty, ensure sustainable economic development, and control health hazards. The aim of this paper is to produce a 'report card' on Canada's success in reducing socioeconomic and health inequities pertaining to these seven policy domains, and to assess how Canadian trends compare to those in the United Kingdom (UK), a country with a similar health and welfare system. Summarising evidence from published studies and national statistics, we found that Canada's best successes were in reducing socioeconomic inequalities in early learning and child care and reproductive health-specifically in improving equity in maternal employment and infant mortality. Comparative data suggest that Canada's outcomes in the latter areas were like those in the UK. In contrast, Canada's least promising equity outcomes were in relation to health hazard control (specifically, tobacco) and child poverty. Though Canada and the UK observed similar inequities in smoking, Canada's slow upward trend in child poverty prevalence is distinct from the UK's small but steady reduction of child poverty. This divergence from the UK's trends indicates that alternative investment types and levels may be needed in Canada to achieve similar outcomes to those in the UK. PMID- 30302367 TI - Comparison of the locations where young adults smoke, vape, and eat/drink cannabis: Implications for harm reduction. AB - Background: Cannabis vaping and edible use are increasingly popular methods of cannabis use. These discreet methods could increase risk of cannabis-related problems by facilitating cannabis use in a wider range of settings. Methods: A sample of 1018 college students were recruited to complete a survey about their health and behavior. Participants who used cannabis in the past year (35.1%, n = 357) answered questions about their cannabis use, including where they were the last time they smoked, vaped, or ate/drank cannabis, and their experience of cannabis-related problems. Results: Compared with cannabis smoking, participants were more likely to have vaped cannabis (15.8% smoked vs. 24.6% vaped; X2 = 4.59, p = .032), and were slightly, but not statistically significantly, more likely to have used cannabis edibles (17.5% smoked vs. 24.2% used edibles; X2 = 3.57, p = .059), in locations other than a private residence. For example, participants were more likely to have vaped cannabis in a car than to have smoked cannabis in a car (8.8% vaped vs. 3.5% smoked; X2 = 4.26, p = .039). More frequent cannabis vaping was associated with driving while high on cannabis, even after accounting for overall frequency of cannabis use and other covariates (OR = 1.22, p = .047). More frequent cannabis vaping and edible use were associated with various cannabis-related problems, but, in general, these associations became statistically non-significant after accounting for overall frequency of cannabis use. Conclusions: Cannabis vaporizers and edibles facilitate cannabis use in locations that require discretion. Increased availability of cannabis vaporizers and edibles could increase risk of cannabis-related problems by enabling use in more settings.

AB - Introduction: Affective changes precede cognitive decline in mild Alzheimer's disease and may relate to increased connectivity in a "salience network" attuned to emotionally significant stimuli. The trajectory of affective changes in preclinical Alzheimer's disease, and its relationship to this network, is unknown. Methods: One hundred one cognitively normal older adults received longitudinal assessments of affective symptoms, then amyloid-PET. We hypothesized amyloid-positive individuals would show enhanced emotional reactivity associated with salience network connectivity. We tested whether increased global connectivity in key regions significantly related to affective changes. Results: In participants later found to be amyloid positive, emotional reactivity increased with age, and interpersonal warmth declined in women. These individuals showed higher global connectivity within the right insula and superior temporal sulcus; higher superior temporal sulcus connectivity predicted increasing emotional reactivity and decreasing interpersonal warmth. Conclusions: Affective changes should be considered an early preclinical feature of Alzheimer's disease. These changes may relate to higher functional connectivity in regions critical for social-emotional processing. PMID- 30302369 TI - Efficacy of temperature-guided cryoballoon ablation without using real-time recordings - 12-Month follow-up. AB - Background: We sought to evaluate a temperature-guided approach of cryoballoon (CB) ablation without visualization of real-time recordings. Methods and results: We analysed 166 patients (34.9% female, 60 +/- 11 years) with paroxysmal or short term persistent atrial fibrillation (AF). Comorbidities included diabetes mellitus (n = 28), coronary artery disease (n = 24), hypertension (n = 122), previous stroke or TIA > 3 months (n = 12). Cryoablation of the pulmonary veins (PV) was performed using first-generation (n = 78) and second-generation CB (n = 88). Two 5-minute freezes were performed for the first-generation and two 4 minute freezes for the second-generation CB with the intention to achieve a temperature drop below -40 degrees C. At 12-month follow-up, we observed overall freedom from AF in 92 patients (56.6%, mean time to AF recurrence 3.4 +/- 2.9 months). There was a significant difference in freedom from AF between first generation CB (45%) and second-generation CB (67%; p < 0.005). Complications were groin hematoma (4.8%) and phrenic nerve palsy (PVP) (2.4%). PVP disappeared after 12 months in all patients. Three patients developed cardiac tamponade (1.8%) that resolved without further sequelae after pericardiocentesis. Multivariate analysis revealed that only the achieved temperature in the right inferior PV (RIPV) was a predictor of long-term freedom from AF (OR 0.9; p = 0.014). Female gender was a predictor of AF recurrence (OR 6.1; p = 0.022). Conclusion: Temperature-guided CB ablation without real-time recordings is feasible and safe without reducing the efficacy if second-generation CB is used. Deep nadir temperatures especially in the RIPV are necessary for long term-success.

PMID- 30302371 TI - Efficacy and tolerability of various bowel preparations in diabetic patients: a randomized controlled trial. AB - Background and study aims Diabetes mellitus (DM) is an independent risk factor for poor bowel preparation prior to colonoscopy. Bisacodyl is a stimulant laxative that may mitigate colonic dysmotility associated with diabetes. We hypothesized that adding bisacodyl to split-dose bowel preparation (SDBP) would improve the quality of bowel preparation among patients with diabetes. Patients and methods Adult outpatients aged 18 to 80 years undergoing colonoscopy were recruited. One hundred and eighty-six patients with diabetes were randomly assigned to 1 of 3 treatment arms: 1) conventional 4 L of polyethylene glycol electrolyte lavage solution (PEG-ELS; conventional bowel preparation [CBP]); 2) split-dose of 4 L PEG-ELS (split-dose bowel preparation [SDBP]); or 3) split-dose of 4 L PEG-ELS preceded by 10 mg of oral bisacodyl 10 (SDBP-B). The primary outcome measure was bowel cleansing as indicated by Boston Bowel Preparation Scale (BBPS) score. Endoscopists were blinded to the preparation used. Secondary outcome measures were safety and patient tolerability. Results Of the 212 patients randomized, only 186 received assigned bowel preparation. There were no differences among the three study groups with regard to age, indication, duration of DM, insulin use, narcotic use, or presence of end-organ diabetic complications. There was a trend toward better bowel preparation quality among those receiving SDBP and SDBP-B compared to those receiving CBP, but the trend was not statistically significant >= 6 BBPS; 67 % vs. 83 % vs. 75 %, P = 0.1). In terms of safety and tolerability, there were no differences among the three groups. Conclusion Adding bisacodyl to SDBP does not improve the quality of bowel preparation in patients with DM. Further efforts are needed to optimize colonoscopy bowel preparation in this population. PMID- 30302372 TI - Evaluation of a 12-mm diameter covered self-expandable end bare metal stent for malignant biliary obstruction. AB - Background and study aims Biliary metallic stents are used to drain unresectable malignant distal biliary obstructions. This study aimed to evaluate the efficacy of a novel 12-mm-diameter covered, self-expandable end bare metal stent (12-mm CSEEMS). Patients and methods We evaluated 99 patients with unresectable malignant distal biliary obstructions treated with covered biliary metallic stents. Of the 99 patients, 33 underwent 12-mm CSEEMS placement between June 2015 and April 2017 (12-mm-CSEEMS group) and 66 underwent 10-mm fully-covered self expandable metal stent (FCSEMS) placement between January 2010 and July 2015 (10 mm-FCSEMS group). The overall survival (OS), the recurrent biliary obstruction (RBO), cause of RBO, time to RBO (TRBO) and adverse events in 12-mm-CSEEMS group and 10-mm-FCSEMS group were evaluated retrospectively. Results The OS tended to be longer in the 12-mm-CSEEMS group (log rank, P = 0.081) and TRBO was significantly longer in the 12-mm-CSEEMS group (log rank, P = 0.001) than in the 10-mm-FCSEMS group. Both univariate (HR, 0.449; 95 % CI, 0.27967 - 0.72215; P = 0.001) and multivariate (HR, 0.458; 95 % CI, 0.28395 - 0.73744; P = 0.001) Cox hazard analysis found that risk of RBO was significantly lower in 12-mm CSEEMS than in 10-mm FCSEMS. There were no significant differences between the 12-mm CSEEMS group and 10-mm-FCSEMS group regarding the cause of RBO and adverse events. Conclusions The 12-mm CSEEMS showed a low risk of RBO compared with 10 mm FCSEMS and was considered to be effective and safe for draining unresectable malignant distal biliary obstruction. PMID- 30302373 TI - Role of routine upper endoscopy before bariatric surgery in the Middle East population: a review of 1278 patients. AB - Introduction The routine use of preoperative endoscopy for patients undergoing bariatric surgery is controversial. Although many surgeons find it unnecessary, others still consider it a mandatory tool in preoperative assessment. Patients and methods We reviewed the medical records of all patients who had undergone preoperative endoscopy before bariatric surgery in Rashid Hospital between January 2013 and June 2016. The patients were divided into three groups: Group 0 included patients with normal endoscopy; Group 1 included patients with abnormalities that did not affect the timing or type of procedure; Group 2 included patients with abnormalities that had a direct impact on the procedure. Results The files of 1473 patients were reviewed. Endoscopy results were not present in 195 files, so those patients were excluded, and the remaining 1278 files were included. The mean age of patients was 41.3 +/- 12.7 years, 61 % were female and 39 % were male. The mean body mass index (BMI) was 43.7 +/- 8 kg/m 2 . Endoscopy was normal in 10.6 % of patients and abnormal in 89.4 %. The most common abnormalities were gastritis, positive Campylobacter-like organism test (CLO test), gastroesophageal reflux disease (GERD) with esophagitis and hiatal hernia. Group 0 included 10.6 % of patients (n = 135), Group 1 included 25.6 % of patients (n = 327), while Group 2 included 63.8 % of patients (n = 816). Conclusion Routine endoscopy seems to play an important part in the preoperative preparation of patients planned for bariatric surgery in the Middle East population. Further studies or meta-analysis could help in building up clear solid evidence and guidelines that could be approved by international bariatric associations with regard to indications for preoperative upper endoscopy in bariatric patients. PMID- 30302374 TI - Linked color imaging improves detection of minimal change esophagitis in non erosive reflux esophagitis patients. AB - Background and study aims Non-erosive reflux disease (NERD) includes minimal change esophagitis (MCE) and no endoscopic abnormalities. However, for most endoscopists, it is difficult to detect MCE with conventional white-light endoscopy (WLE). Linked color imaging (LCI) technology is the most recently developed image-enhancing technology and improves detection and differentiation of subtle mucosal changes using a color contrast method. This study assessed the efficacy of WLE combined with LCI for diagnosing MCE compared with WLE. Patients and methods Between February and May 2017, 44 NERD patients and 40 healthy subjects were enrolled in our study. First, the distal esophagus was examined using WLE followed by LCI. Second, three experienced endoscopists observed all the patients' white-light (WL) images and corresponding images of WL and LCI and then recorded presence or absence of minimal change esophagitis (MCE +/-). The proportion of minimal change between the two groups was then compared. Third, five blinded endoscopists with different levels of endoscopic experience assessed whether MCE was present. Intraobserver reproducibility and interobserver agreement were described using the kappa value. Results The proportion of MCE in the NERD group (70.8 %, 35/48) was higher than that in the control group (22.5 %, 9/40, P < 0.001) when diagnosed by the three experienced endoscopists. Detection rates for MCE using WLE combined with LCI were higher than those using WLE (43/88, 48.9 % vs. 29/88, 33.0 %, P < 0.001). With WLE combined with LCI, intraobserver reproducibility significantly improved, indicating that the combined approach can improve interobserver agreement compared with using WLE alone. Conclusions Endoscopic diagnosis of MCE using WLE combined with LCI images is effective. Intraobserver reproducibility and interobserver agreement in MCE can be improved when LCI is applied with conventional imaging (Clinical trial registration number: NCT03068572). PMID- 30302375 TI - Insertability comparison of passive bending single-balloon prototype versus standard single-balloon enteroscopy: a multicenter randomized non-blinded trial. AB - Background and study aims Traversing the ileocecal valve (ICV) is technically challenging with a retrograde approach to single-balloon enteroscopy (SBE). A novel technique called responsive insertion technology (RIT) colonoscopy was developed to obtain a higher cecal intubation rate in this setting. A prototype long SBE equipped with RIT (P-SBE) was developed to obtain superior insertability. The aim of this study was to compare the insertability of a standard single-balloon enteroscope (S-SBE) versus a P-SBE. Patients and methods This study was a multicenter, randomized, non-blinded, trial of 62 patients with small bowel pathologies. All procedures were performed with SBE via the trans anal route. Procedure success was defined as stable intubation of the terminal ileum (TI) 20 cm beyond the ICV. The primary variable was time to reach stable TI intubation 20 cm beyond the ICV (TSTII). If stable TI intubation was not achieved within 10 minutes, the initial SBE was removed through the indwelling overtube and replaced with another SBE. Results Sixty patients were examined with two patients excluded from this study. TSTII using P-SBE was significantly decreased compared to S-SBE (mean P-SBE vs S-SBE: 98.3 vs 169.4 second, P = 0.006). The completion rates for stable intubation within 10 minutes of using P-SBE and S-SBE were 96.8 % and 86.2 %, respectively ( P = 0.19). On endoscope replacement, all patients had achieved stable TI intubation. Conclusions SBE with RIT improves insertability when traversing the ileocecal valve in retrograde SBE. PMID- 30302376 TI - Differences in upper gastrointestinal neoplasm detection rates based on inspection time and esophagogastroduodenoscopy training. AB - Background and study aims Esophagogastroduodenoscopy (EGD) has utility in early detection of upper gastrointestinal (UGI) neoplasms. However, previous studies report shorter inspection times and inexperienced endoscopists contribute to overlooking gastric neoplasms. We investigated neoplasm detection rates according to inspection time and extent of EGD training. Patients and methods In this retrospective observational study, we reviewed routine EGDs for 3,925 consecutive cases between October 2014 and March 2015. We divided the endoscopists into three groups based on median inspection time during EGD without undergoing biopsy. Using cut-off median inspection times of 7 and 10 minutes, three, five, and eight endoscopists were classified into the fast, moderate, and slow groups, respectively. We compared detection rates according to inspection time and the extent of EGD training. Results The median inspection time among all endoscopists was 9.3 minutes (range, 6.6 - 12.0 min). The detection rate for UGI neoplasms was as follows: fast group, 3.6%; moderate group, 3.3 %; and slow group, 3.1 % ( P = 0.807). The median inspection time was significantly shorter among the intensive training >= 1-year group than among the < 1-year group (< 1 year: median 6.3 min; range 8.2 - 13.9 min, >= 1-year: median 8.9 min; range 6.4 11.4 min, P < 0.001). The detection rate for UGI neoplasms was significantly higher among the intensive training >= 1-year group than among the < 1-year group (< 1-year: 2.2 %; >= 1-year: 3.7 %, OR = 1.65, 95 % CI: 1.02 - 2.68, P = 0.041). Conclusions There was no association between inspection times and neoplasm detection rates. The quality of EGD, as measured by neoplasm detection rates, may be improved by >= 1-year of intensive training. PMID- 30302377 TI - Polypoid nodule scar after gastric endoscopic submucosal dissection: results from a multicenter study. AB - Background and study aims A post-endoscopic submucosal dissection (ESD) scar is expected to look homogeneous, however, some patients develop benign polypoid nodule scar (PNS). Incidence of PNS is unknown, yet these scars have direct clinical implications because they may render evaluation of post-ESD neoplastic recurrence difficult. Therefore, we reviewed the clinical experience of 5 ESD referral centers and evaluated their PNS incidence and clinical management. Patients and methods This was a retrospective multicenter case series enrolling patients that underwent R0, curative gastric ESD from 2003 to 2015 in 5 academic centers. PNS was defined as ESD site nodularity with hyperplastic or regenerative tissue histology. Results A total of 2275 patients underwent gastric ESD with endoscopy control and 28 patients (18 men/10 women) developed PNS for overall incidence of 1.2 %. Incidence of PNS ranged from 0.15 % to 11.4 % between centers. All patients that developed PNS had primary neoplastic lesions located in the distal stomach. Considering only lesions situated in the antrum (n = 912), incidence of PNS was 3.1 %. After mean follow-up of 43 months (range 6 - 192), no malignant recurrence in the PNS has been identified. In five patients (17.8 %) PNS disappeared after a mean of 18 months. Conclusion PNS occurs exclusively after ESD in the distal stomach in approximately 3.1 % of patients. Although PNS appearance can be concerning, no malignant recurrence was observed after curative R0 resection. Therefore, PNS should be viewed as a benign alteration that does not require any type of intervention, other than endoscopic surveillance. PMID- 30302378 TI - A comparative review of use of sulphate and phosphate salts for colonoscopy preparations and their potential for nephrotoxicity. AB - Background and study aims Colonoscopy is a widely used diagnostic procedure which requires prior cleansing of the bowel. Many different bowel cleansing preparations have been developed, all of which have specific advantages and disadvantages. This review compares two low-volume high-osmolarity bowel cleansing preparations, oral phosphate salts and oral sulphate salts, with a particular focus on risk of nephrotoxicity. Patients and methods An electronic search of the Medline database was performed using the search terms "(phosphates OR sulfates) AND cathartics [MeSH Term] AND kidney" restricted to humans with a cut-off date of December 31, 2016. Results Introduction of oral phosphate salts offered the advantage of low intake volume and low risk of bowel irritation compared to previous options. However, phosphate salts have been associated with renal toxicity (acute phosphate nephropathy [APN]), thought to arise due to perturbations of calcium and phosphate homeostasis as a consequence of increases in serum phosphate. This results in high concentrations of calcium phosphate in the distal tubule and collecting ducts of the kidney, where it may precipitate. Although APN is rare, it may lead to permanent kidney damage. For this reason, phosphate salts are contraindicated in vulnerable patient groups. As an alternative to phosphate salts, oral sulphate salts have recently been introduced. Because sulphate absorption from the intestinal tract is saturable, serum sulphate concentrations increase only minimally after ingestion. Furthermore, excretion of sulphate in the kidney is not accompanied by calcium excretion and urine calcium levels are unchanged. For these theoretical reasons, use of sulphate salts as bowel cleansing solutions is not expected to lead to calcium precipitation in the nephron. Conclusions Oral phosphate salts are no longer recommended for routine use as bowel cleansing preparations as they carry significant risk of kidney damage and a safer alternative is available in the form of oral sulphate solutions. To date, use of sulphate salts has not been associated with elevations in serum creatinine or other markers of renal impairment, nor with clinical manifestations of kidney injury. Nonetheless, experience with sulphate salts in everyday practice is limited and physicians should be vigilant in detecting potential safety issues. PMID- 30302379 TI - Cap-assisted colonoscopy: a meta-analysis of high-quality randomized controlled trials. AB - Background and study aims Standard colonoscopy (SC) is the preferred modality for screening for colon cancer; however, it carries a significant polyp/adenoma miss rate. Cap-assisted colonoscopy (CC) has been shown to improve polyp/adenoma detection rate, decrease cecal intubation time and increase cecal intubation rate when compared to standard colonoscopy (SC). However, data on adenoma detection rate (ADR) are conflicting. The aim of this meta-analysis was to compare the performance of CC with SC for ADR among high-quality randomized controlled trials. Patients and methods We performed an extensive literature search using MEDLINE, EMBASE, Scopus, Cochrane and Web of Science databases and abstracts published at national meetings. Only comparative studies between CC and SC were included if they reported ADR, adenoma per person (APP), cecal intubation rate, and cecal intubation time. The exclusion criterion for comparing ADR was studies with Jadad score <= 2. The odds ratio (OR) was calculated using Mantel-Haenszel method. I 2 test was used to measure heterogeneity among studies. Results Analysis of high-quality studies (Jadad score >= 3, total of 7 studies) showed that use of cap improved the ADR with the results being statistically significant (OR 1.18, 95 % CI 1.03 - 1.33) and detection of 0.16 (0.02 - 0.30) additional APP. The cecal intubation rate in the CC group was 96.3 % compared to 94.5 % with SC (total of 17 studies). Use of cap improved cecal intubation (OR 1.61, 95 % CI 1.33 - 1.95) when compared to SC ( P value < 0.001). Use of cap decreased cecal intubation time by an average of 0.88 minutes (95 % CI 0.37 - 1.39) or 53 seconds. Conclusions Meta-analysis of high-quality studies showed that CC improved the ADR compared to SC. PMID- 30302380 TI - Endoscopic full-thickness resection in the colorectum: a single-center case series evaluating indication, efficacy and safety. AB - Background and study aims Endoscopic full-thickness resection (eFTR) allows en bloc and transmural resection of colorectal lesions for which other advanced endoscopic techniques are unsuitable. We present our experience with a novel "clip first, cut later" eFTR-device and evaluate its indications, efficacy and safety. Patients and methods From July 2015 through October 2017, 51 eFTR procedures were performed in 48 patients. Technical success and R0-resection rates were prospectively recorded and retrospectively analyzed. Results Indications for eFTR were non-lifting adenoma (n = 19), primary resection of malignant lesion (n = 2), resection of scar tissue after incomplete endoscopic resection of low-risk T1 colorectal carcinoma (n = 26), adenoma involving a diverticulum (n = 2) and neuroendocrine tumor (n = 2). Two lesions were treated by combining endoscopic mucosal resection and eFTR. Technical success was achieved in 45 of 51 procedures (88 %). Histopathology confirmed full-thickness resection in 43 of 50 specimens (86 %) and radical resection (R0) in 40 procedures (80 %). eFTR-specimens, obtained for indeterminate previous T1 colorectal carcinoma resection, were free of residual carcinoma in 25 of 26 cases (96 %). In six patients (13 %) a total of eight adverse events occurred within 30 days after eFTR. One perforation occurred, which was corrected endoscopically. No emergency surgery was necessary. Conclusion In this study eFTR appears to be safe and effective for the resection of colorectal lesions. Technical success, R0 resection and major adverse events rate were reasonable and comparable with eFTR data reported elsewhere. Mean specimen diameter (23 mm) limits its use to relatively small lesions. A clinical algorithm for eFTR case selection is proposed. eFTR ensured local radical excision where other endoscopic techniques did not suffice and reduced the need for surgery in selected cases. PMID- 30302381 TI - Evaluation of a new pan-enteric video capsule endoscopy system in patients with suspected or established inflammatory bowel disease - feasibility study. AB - Background and study aims Inflammatory bowel disease (IBD) affects the small bowel and colon. Endoscopic evaluation of these organs is essential. The new pan enteric Crohn's capsule (PCC) system is customized for complete coverage of IBD lesions in the entire bowel, allowing assessment and follow-up of disease severity and extent. The aim of this study was to evaluate the functionality of the PCC system in patients with suspected or established IBD. Patients and methods This was a prospective five-center feasibility study assessing the performance of PCC. Subjects ingested PCC after patency assurance with standard bowel preparation plus boosts. The primary endpoint was successful procedure, that is, video creation and report generation in accordance with methodology. Secondary endpoints were subjective coverage of the entire bowel, duration of reading time, video quality and occurrence of adverse events. Results Forty-one patients were included in the study with a mean age of 40.8 years +/- 15.5, 46 % of whom were males. Seventy-one percent of patients had established Crohn's disease (CD) and 53 % had active disease. Cleansing was graded good/excellent in 95 %. All 41 videos met the primary endpoint. There was no retention, 83 % reached the toilet while still recording. Thirty-one percent of patients with CD had proximal disease. Bowel coverage was graded 6.7 +/- 0.6 and 6.1 +/- 1.3 (1 - 7, unconfident - confident), image quality 6.1 +/- 0.8 (1 - 7, poor - excellent), and reading time 3.7 +/- 1.4 (1 - 7, very short to very long). Conclusions The PCC system is a minimally invasive system allowing extensive evaluation of the entire bowel in patients with IBD.

For this, an International Affairs Working Group (IAWG) was formed. In conjunction with the World Endoscopy Organization (WEO), ESGE conducted a survey of gastrointestinal (GI) endoscopy in Africa. Survey results showed that many African countries have few GI endoscopy centers with adequate resources. Barriers to the development of endoscopy services include a shortage of endoscopists who have undergone advanced endoscopy training, and a lack of equipment and basic infrastructure. Diseases related to infectious etiology are more prevalent than neoplastic diseases in Africa. Any development of endoscopy services needs to consider the local prevalence of diseases for which GI endoscopy is required, as well as the availability of resources. The IAWG will initiate a cascade approach to identify and adapt ESGE guidelines for local use. The guidelines will consider the level of resources available for each intervention, as well as cost, infrastructure, and training, and will be approved by consensus of local experts who are representative of different African areas. Suitable centers in African countries will be identified, and in future will be developed into WEO/ESGE training centers, to provide local training in both basic and advanced endoscopy according to the needs of the area.

PMID- 30302385 TI - Safety and rate of delayed adverse events with lumen-apposing metal stents (LAMS) for pancreatic fluid collections: a multicenter study. AB - Background and study aims Endoscopic drainage with dedicated lumen-apposing metal stents (LAMS) is routinely performed for symptomatic pancreatic fluid collections (PFCs), walled-off necrosis (WON) and pseudocyst (PP). There has been increasing concern regarding delayed adverse events associated with the indwelling LAMS. Patients and methods Multicenter retrospective analysis of consecutive patients who underwent endoscopic ultrasound (EUS)-guided LAMS placement for PFC from January 2010 to May 2017. Main outcomes included: (1) resolution of the PFC, (2) rate of delayed adverse events at follow-up, and (3) predictors of treatment failure and delayed adverse events on logistic regression. Results A total of 122 patients (mean age 50.9 years, 68 % male) underwent LAMS insertion for 64 WON (98.4 %) and 58 PP (98.3 %). PFC mean size was 10.6 cm. PFC resolution was significantly lower for WON (62.3 %) vs. PP (96.5 %) ( P < 0.001) on imaging at a median of 4 weeks. Stent occlusion was identified in 18 (29.5 %) and 10 (17.5 %) patients with WON and PP, respectively ( P = 0.13). There were no cases of delayed bleeding or buried stent on follow up endoscopy. Use of electrocautery-enhanced LAMS was the only factor associated with treatment failure of WON (OR = 13.2; 95 % ci: 3.33 - 51.82, P = 0.02) on logistic regression. There were no patient, operator, or procedure-related factors predictive of stent occlusion. Conclusions EUS-guided LAMS for PFC is associated with a low incidence of delayed adverse events. While nearly all PPs resolve at 4 weeks permitting LAMS removal shortly thereafter, many WON persist, with use of electrocautery-enhanced LAMS being the sole predictor of treatment failure. PMID- 30302387 TI - EUS fine-needle pancreatic core biopsy can determine eligibility for tumor agnostic immunotherapy. AB - Background and study aims The US FDA recently approved a cancer treatment with pembrolizumab based upon the tumor biomarker status of deficient mismatch repair (dMMR) rather than a specific disease-based approach. We sought to determine if endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) could determine dMMR and quantification of PD-L1 expression to potentially guide the delivery of tumor agnostic immunotherapy. Patients and methods Immunohistochemistry was performed on archived pancreas core biopsy specimens. Tumors with absent nuclear staining of DNA mismatch repair proteins represented dMMR. Tumors were considered to have any or high PD-L1 expression, if expressed in >= 1 % or >= 50 % of tumor cells. Results Histologic specimen adequacy for MMR status assessment was satisfactory in 97.2 % of tumors. dMMR and high PD-L1 expression was identified in 3 % and 8.1 % of the cohort. Conclusion In the setting of tumor type agnostic immunotherapy, it is projected that at least 3 % of malignant pancreas lesions will be sensitive to pembrolizumab and up to 8 % sensitive to the family of immune checkpoint inhibitors. This highlights the expanding role of EUS-FNB in the field of precision immuno-oncology. PMID- 30302388 TI - Behavioral Phenotyping of an Improved Mouse Model of Phelan-McDermid Syndrome with a Complete Deletion of the Shank3 Gene. AB - Phelan-McDermid syndrome (PMS) is a rare genetic disorder in which one copy of the SHANK3 gene is missing or mutated, leading to a global developmental delay, intellectual disability (ID), and autism. Multiple intragenic promoters and alternatively spliced exons are responsible for the formation of numerous isoforms. Many genetically-modified mouse models of PMS have been generated but most disrupt only some of the isoforms. In contrast, the vast majority of known SHANK3 mutations found in patients involve deletions that disrupt all isoforms. Here, we report the production and thorough behavioral characterization of a new mouse model in which all Shank3 isoforms are disrupted. Domains and tasks examined in adults included measures of general health, neurological reflexes, motor abilities, sensory reactivity, social behavior, repetitive behaviors, cognition and behavioral inflexibility, and anxiety. Our mice are more severely affected than previously published models. While the deficits were typically more pronounced in homozygotes, an intermediate phenotype was observed for heterozygotes in many paradigms. As in other Shank3 mouse models, stereotypies, including increased grooming, were observed. Additionally, sensory alterations were detected in both neonatal and adult mice, and motor behavior was strongly altered, especially in the open field and rotarod locomotor tests. While social behaviors measured with the three-chambered social approach and male-female interaction tests were not strongly impacted, Shank3-deficient mice displayed a strong escape behavior and avoidance of inanimate objects in novel object recognition, repetitive novel object contact, marble burying, and nest building tasks, indicating increased novelty-induced anxiety. Similarly, increased freezing was observed during fear conditioning training and amygdala-dependent cued retrieval. Finally, deficits were observed in both initial training and reversal in the Barnes maze and in contextual fear testing, which are memory tasks involving hippocampal-prefrontal circuits. In contrast, working memory in the Y-maze spontaneous alternation test was not altered. This new mouse model of PMS, engineered to most closely represent human mutations, recapitulates core symptoms of PMS providing improvements for both construct and face validity, compared to previous models. PMID- 30302389 TI - Selective Effects of the Loss of NMDA or mGluR5 Receptors in the Reward System on Adaptive Decision-Making. AB - Selecting the most advantageous actions in a changing environment is a central feature of adaptive behavior. The midbrain dopamine (DA) neurons along with the major targets of their projections, including dopaminoceptive neurons in the frontal cortex and basal ganglia, play a key role in this process. Here, we investigate the consequences of a selective genetic disruption of NMDA receptor and metabotropic glutamate receptor 5 (mGluR5) in the DA system on adaptive choice behavior in mice. We tested the effects of the mutation on performance in the probabilistic reinforcement learning and probability-discounting tasks. In case of the probabilistic choice, both the loss of NMDA receptors in dopaminergic neurons or the loss mGluR5 receptors in D1 receptor-expressing dopaminoceptive neurons reduced the probability of selecting the more rewarded alternative and lowered the likelihood of returning to the previously rewarded alternative (win stay). When observed behavior was fitted to reinforcement learning models, we found that these two mutations were associated with a reduced effect of the expected outcome on choice (i.e., more random choices). None of the mutations affected probability discounting, which indicates that all animals had a normal ability to assess probability. However, in both behavioral tasks animals with targeted loss of NMDA receptors in dopaminergic neurons or mGluR5 receptors in D1 neurons were significantly slower to perform choices. In conclusion, these results show that glutamate receptor-dependent signaling in the DA system is essential for the speed and accuracy of choices, but at the same time probably is not critical for correct estimation of probable outcomes. PMID- 30302390 TI - Adaptation and Inhibition Control Pathological Synchronization in a Model of Focal Epileptic Seizure. AB - Pharmacoresistant epilepsy is a common neurological disorder in which increased neuronal intrinsic excitability and synaptic excitation lead to pathologically synchronous behavior in the brain. In the majority of experimental and theoretical epilepsy models, epilepsy is associated with reduced inhibition in the pathological neural circuits, yet effects of intrinsic excitability are usually not explicitly analyzed. Here we present a novel neural mass model that includes intrinsic excitability in the form of spike-frequency adaptation in the excitatory population. We validated our model using local field potential (LFP) data recorded from human hippocampal/subicular slices. We found that synaptic conductances and slow adaptation in the excitatory population both play essential roles for generating seizures and pre-ictal oscillations. Using bifurcation analysis, we found that transitions towards seizure and back to the resting state take place via Andronov-Hopf bifurcations. These simulations therefore suggest that single neuron adaptation as well as synaptic inhibition are responsible for orchestrating seizure dynamics and transition towards the epileptic state. PMID- 30302392 TI - 'Levodopa Phobia': a review of a not uncommon and consequential phenomenon. AB - 'Levodopa Phobia' is under-recognised in Parkinson's disease but can cause profound detrimental clinical complications if left to continue. Several types can be encountered in clinical practice and can be driven by a misplaced fear of levodopa-induced dyskinesias, other gastrointestinal side effects and also the theoretical notion that levodopa may be toxic to dopaminergic neurons in the brain. The condition can be underpinned by a sense of strong influence from the physicians or carers who are unwilling to prescribe or consider levodopa, and also high levels of anxiety or even impulsive compulsive traits in patients who have been influenced by available literature or social media-based information. If unrecognised, the clinical issue may lead to motor deterioration and related muscle contractures leading to social isolation as well as a range of non-motor symptoms. In some, there may be emergence of intrusive impulse control disorders because of reliance on only dopamine agonists related to the fear of taking levodopa. Four cases illustrate the different patterns of 'Levodopa Phobia' in this study. Management of levodopa phobia is complex and includes recognition and skilled neuropsychological interventions to break the misperceptions about the complications of levodopa therapy. PMID- 30302391 TI - Ingestion of subthreshold doses of environmental toxins induces ascending Parkinsonism in the rat. AB - Increasing evidence suggests that environmental neurotoxicants or misfolded alpha synuclein generated by such neurotoxicants are transported from the gastrointestinal tract to the central nervous system via the vagus nerve, triggering degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNpc) and causing Parkinson's disease (PD). We tested the hypothesis that gastric co-administration of subthreshold doses of lectins and paraquat can recreate the pathology and behavioral manifestations of PD in rats. A solution containing paraquat + lectin was administered daily for 7 days via gastric gavage, followed by testing for Parkinsonian behavior and gastric dysmotility. At the end of the experiment, brainstem and midbrain tissues were analyzed for the presence of misfolded alpha-synuclein and neuronal loss in the SNpc and in the dorsal motor nucleus of the vagus (DMV). Misfolded alpha-synuclein was found in DMV and SNpc neurons. A significant decrease in tyrosine hydroxylase positive dopaminergic neurons was noted in the SNpc, conversely there was no apparent loss of cholinergic neurons of the DMV. Nigrovagally-evoked gastric motility was impaired in treated rats prior to the onset of parkinsonism, the motor deficits of which were improved by l-dopa treatment. Vagotomy prevented the development of parkinsonian symptoms and constrained the appearance of misfolded alpha-synuclein to myenteric neurons. These data demonstrate that co-administration of subthreshold doses of paraquat and lectin induces progressive, l-dopa-responsive parkinsonism that is preceded by gastric dysmotility. This novel preclinical model of environmentally triggered PD provides functional support for Braak's staging hypothesis of idiopathic PD. PMID- 30302393 TI - The effect of mild decrement in plasma volume simulating short-duration spaceflight on intracranial pressure. AB - Short-duration spaceflight induces an approximately 10% reduction in plasma volume, which leads to mild volume depletion. In a previous study, we found that mild volume depletion improved dynamic cerebral autoregulation. However, the effect of mild volume depletion on intracranial pressure (ICP) remains unknown. Therefore, we estimated ICP noninvasively (nICP), and calculated two indices relating to ICP, the cerebral artery compliance and the cerebral blood flow pulsatility index (PI), to examine whether ICP would decrease due to a mild decrement in plasma volume. In our previous experiment, fourteen subjects were administered 0.2 mg/kg of furosemide in a supine position to simulate an approximately 10% reduction in plasma volume induced by short-duration spaceflight. We re-analyzed the cerebral blood flow velocity waveform from the middle cerebral artery obtained by transcranial Doppler and the arterial blood pressure waveform at the radial artery obtained by tonometry to estimate nICP and to calculate cerebral artery compliance and PI using mathematical analysis based on an intracranial hydraulic model. All indices were compared between before and after furosemide administration. There were no significant changes in nICP and cerebral artery compliance. However, PI decreased significantly from before to after furosemide administration (0.78 +/- 0.10 to 0.74 +/- 0.09, p = 0.009). Decreases in ICP were not observed during the 10% reduction in plasma volume. Although cerebral artery compliance did not change, PI decreased significantly. These findings suggest that the impedance of distal cerebral arteries would be reduced in response to mild decreases in plasma volume induced by short-duration spaceflight. PMID- 30302395 TI - Adaptation of the Roseman 6-Point Mastery Learning Model to the College of Medicine Program. AB - Medical education has evolved over time toward a model which integrates clinical medicine with the basic sciences. More recently, medical education has put an emphasis on outcome-based education. Other areas of health care education have had a similar emphasis which can provide models to inform a new model for medical education. The Roseman University of Health Sciences has developed and implemented a model based on underlying tenets of mastery learning since 1999. The model has been implemented in pharmacy, nursing, and dental education. It was conceived as an integration of 6 key points which reinforce each other and interrelate to support learning. The model has been modified for application to medical education in support of medical education's outcome-based emphasis and to address the educational demands of the changing environment of the practice of medicine. PMID- 30302394 TI - Activation and Utilization of an Electronic Health Record Patient Portal at an Academic Medical Center-Impact of Patient Demographics and Geographic Location. AB - The advent of the online electronic health record patient portal has provided an efficient and practical means for patients to become more involved in their health care. In this report, we analyze how demographic variables such as age, gender, race, and geographic location affect patient portal activation and usage at the University of Iowa Hospitals and Clinics, the sole academic medical center in the state of Iowa, a predominantly rural state. Our primary end points were activation of the patient portal (MyChart, Epic, Inc) and access of outpatient laboratory and radiology results, among the most commonly accessed and popular features of the patient portal. We thus analyzed data from 536 378 patients to determine rates of patient portal activation and data from 219 671 patient encounters to determine the frequency at which patients access their online diagnostic test results. Higher rates of patient portal activation and usage were associated with female gender, Caucasians/non-underrepresented minorities, geographic location in closer proximity to the medical center (Iowa City and neighboring cities/suburbs), and nonelderly adults. For underrepresented minority and rural patients, opportunities for improvement exist for both activation and more robust use of online patient portal accounts. Overall, these data highlight existing disparities with online patient portal usage and provide a base on which further studies and interventions can help to improve utilization of these systems. PMID- 30302396 TI - Effects of Advanced Cardiac Procedure Simulator Training on Learning and Performance in Cardiovascular Medicine Fellows. AB - Background: Simulation-based training has been used in medical training environments to facilitate the learning of surgical and minimally invasive techniques. We hypothesized that integration of a procedural simulation curriculum into a cardiology fellowship program may be educationally beneficial. Methods: We conducted an 18-month prospective study of cardiology trainees at Vanderbilt University Medical Center. Two consecutive classes of first-year fellows (n = 17) underwent a teaching protocol facilitated by simulated cases and equipment. We performed knowledge and skills evaluations for 3 procedures (transvenous pacing [TVP] wire, intra-aortic balloon pump [IABP], and pericardiocentesis [PC]). The index class of fellows was reevaluated at 18 months postintervention to measure retention. Using nonparametric statistical tests, we compared assessments of the intervention group, at the time of intervention and 18 months, with those of third-year fellows (n = 7) who did not receive simulator based training. Results: Compared with controls, the intervention cohort had higher scores on the postsimulator written assessment, TVP skills assessment, and IABP skills assessment (P = .04, .007, and .02, respectively). However, there was no statistically significant difference in scores on the PC skills assessment between intervention and control groups (P = .08). Skills assessment scores for the intervention group remained higher than the controls at 18 months (P = .01, .004, and .002 for TVP, IABP, and PC, respectively). Participation rate was 100% (24/24). Conclusions: Procedural simulation training may be an effective tool to enhance the acquisition of knowledge and technical skills for cardiology trainees. Future studies may address methods to improve performance retention over time. PMID- 30302397 TI - Emerging role of precision medicine in biliary tract cancers. AB - Biliary tracts cancers (BTCs) are a diverse group of aggressive malignancies with an overall poor prognosis. Genomic characterization has uncovered many putative clinically actionable aberrations that can also facilitate the prognostication of patients. As such, comprehensive genomic profiling is playing a growing role in the clinical management of BTCs. Currently however, there is only one precision medicine approved by the US Food and Drug Administration (FDA) for the treatment of BTCs. Herein, we highlight the prevalence and prognostic, diagnostic, and predictive significance of recurrent mutations and other genomic aberrations with current clinical implications or emerging relevance to clinical practice. Some ongoing clinical trials, as well as future areas of exploration for precision oncology in BTCs are highlighted. PMID- 30302398 TI - A minimal helical-hairpin motif provides molecular-level insights into misfolding and pharmacological rescue of CFTR. AB - Our meagre understanding of CFTR misfolding and its reversal by small-molecule correctors hampers the development of mechanism-based therapies of cystic fibrosis. Here we exploit a helical-hairpin construct-the simplest proxy of membrane-protein tertiary contacts-containing CFTR's transmembrane helices 3 and 4 and its corresponding disease phenotypic mutant V232D to gain molecular-level insights into CFTR misfolding and drug rescue by the corrector Lumacaftor. Using a single-molecule FRET approach to study hairpin conformations in lipid bilayers, we find that the wild-type hairpin is well folded, whereas the V232D mutant assumes an open conformation in bilayer thicknesses mimicking the endoplasmic reticulum. Addition of Lumacaftor reverses the aberrant opening of the mutant hairpin to restore a compact state as in the wild type. The observed membrane escape of the V232D hairpin and its reversal by Lumacaftor complement cell-based analyses of the full-length protein, thereby providing in vivo and in vitro correlates of CFTR misfolding and drug-action mechanisms. PMID- 30302399 TI - Doxorubicin induces caspase-mediated proteolysis of KV7.1. AB - Kv7.1 (KCNQ1) coassembles with KCNE1 to generate the cardiac IKs -channel. Gain- and loss-of-function mutations in KCNQ1 are associated with cardiac arrhthymias, highlighting the importance of modulating IKs activity for cardiac function. Here, we report proteolysis of Kv7.1 as an irreversible posttranslational modification. The identification of two C-terminal fragments of Kv7.1 led us to identify an aspartate critical for the generation of one of the fragments and caspases as responsible for mediating proteolysis. Activating caspases reduces Kv7.1/KCNE1 currents, which is abrogated in cells expressing caspase-resistant channels. Enhanced cleavage of Kv7.1 can be detected for the LQT mutation G460S, which is located adjacent to the cleavage site, whereas a calmodulin-binding deficient mutation impairs cleavage. Application of apoptotic stimuli or doxorubicin-induced cardiotoxicity provokes caspase-mediated cleavage of endogenous IKs in human cardiomyocytes. In summary, caspases are novel regulatory components of IKs channels that may have important implications for the molecular mechanism of doxorubicin-induced cardiotoxicity. PMID- 30302400 TI - Pinopsin evolved as the ancestral dim-light visual opsin in vertebrates. AB - Pinopsin is the opsin most closely related to vertebrate visual pigments on the phylogenetic tree. This opsin has been discovered among many vertebrates, except mammals and teleosts, and was thought to exclusively function in their brain for extraocular photoreception. Here, we show the possibility that pinopsin also contributes to scotopic vision in some vertebrate species. Pinopsin is distributed in the retina of non-teleost fishes and frogs, especially in their rod photoreceptor cells, in addition to their brain. Moreover, the retinal chromophore of pinopsin exhibits a thermal isomerization rate considerably lower than those of cone visual pigments, but comparable to that of rhodopsin. Therefore, pinopsin can function as a rhodopsin-like visual pigment in the retinas of these lower vertebrates. Since pinopsin diversified before the branching of rhodopsin on the phylogenetic tree, two-step adaptation to scotopic vision would have occurred through the independent acquisition of pinopsin and rhodopsin by the vertebrate lineage. PMID- 30302401 TI - 2D polarization imaging as a low-cost fluorescence method to detect alpha synuclein aggregation ex vivo in models of Parkinson's disease. AB - A hallmark of Parkinson's disease is the formation of large protein-rich aggregates in neurons, where alpha-synuclein is the most abundant protein. A standard approach to visualize aggregation is to fluorescently label the proteins of interest. Then, highly fluorescent regions are assumed to contain aggregated proteins. However, fluorescence brightness alone cannot discriminate micrometer sized regions with high expression of non-aggregated proteins from regions where the proteins are aggregated on the molecular scale. Here, we demonstrate that 2 dimensional polarization imaging can discriminate between preformed non aggregated and aggregated forms of alpha-synuclein, and detect increased aggregation in brain tissues of transgenic mice. This imaging method assesses homo-FRET between labels by measuring fluorescence polarization in excitation and emission simultaneously, which translates into higher contrast than fluorescence anisotropy imaging. Exploring earlier aggregation states of alpha-synuclein using such technically simple imaging method could lead to crucial improvements in our understanding of alpha-synuclein-mediated pathology in Parkinson's Disease. PMID- 30302404 TI - Phytochemical analysis of Canna indica L. roots and rhizomes extract. AB - Canna indica L. (Cannaceae) roots and rhizomes were reported to possess various biological properties like antimicrobial, anthelmintic potential and HIV-1 reverse transcriptase inhibition. In our previous studies, they showed antidiabetic activity on normal rats and rats co-addicted with caffeine and nicotine. In the pursuit of the phytochemical/s responsible for these biological activities, present study was aimed at phytochemical evaluation of hydroalcoholic extract (HAE) of C. indica L. roots and rhizomes; including preliminary screening, thin layer chromatography, H1-NMR and HR-LC/MS-MS analysis. After preliminary detection of flavonoids, tannins and sterols, HAE was tested for presence of beta-sitosterol using TLC. H1-NMR spectrum of HAE revealed the presence of around 761 deshielded protons corresponding to different polar compounds. HR-LC/MS-MS analysis carried out at both positive and negative ion mode, indicated the presence of more than 90 compounds including short fragment of peptide. As per METLIN database, predicted major phytochemicals were 3' hydroxytrimethoprim, 3,7-epoxycaryophyllan-6-one, swietenine, typhasterol, hexacosanedioic acid and 3beta, 6alpha,7alpha-trihydroxy-5beta-cholan-24-oic acid few of which, are biologically active. PMID- 30302402 TI - Genetically engineered minipigs model the major clinical features of human neurofibromatosis type 1. AB - Neurofibromatosis Type 1 (NF1) is a genetic disease caused by mutations in Neurofibromin 1 (NF1). NF1 patients present with a variety of clinical manifestations and are predisposed to cancer development. Many NF1 animal models have been developed, yet none display the spectrum of disease seen in patients and the translational impact of these models has been limited. We describe a minipig model that exhibits clinical hallmarks of NF1, including cafe au lait macules, neurofibromas, and optic pathway glioma. Spontaneous loss of heterozygosity is observed in this model, a phenomenon also described in NF1 patients. Oral administration of a mitogen-activated protein kinase/extracellular signal-regulated kinase inhibitor suppresses Ras signaling. To our knowledge, this model provides an unprecedented opportunity to study the complex biology and natural history of NF1 and could prove indispensable for development of imaging methods, biomarkers, and evaluation of safety and efficacy of NF1-targeted therapies. PMID- 30302403 TI - Alcohol reduces muscle fatigue through atomistic interactions with nicotinic receptors. AB - Alcohol consumption affects many organs and tissues, including skeletal muscle. However, the molecular mechanism of ethanol action on skeletal muscle remains unclear. Here, using molecular dynamics simulations and single channel recordings, we show that ethanol interacts with a negatively charged amino acid within an extracellular region of the neuromuscular nicotinic acetylcholine receptor (nAChR), thereby altering its global conformation and reducing the single channel current amplitude. Charge reversal of the negatively charged amino acid abolishes the nAChR-ethanol interaction. Moreover, using transgenic animals harboring the charge-reversal mutation, ex vivo measurements of muscle force production show that ethanol counters fatigue in wild type but not homozygous alphaE83K mutant animals. In accord, in vivo studies of motor coordination following ethanol administration reveal an approximately twofold improvement for wild type compared to homozygous mutant animals. Together, the converging results from molecular to animal studies suggest that ethanol counters muscle fatigue through its interaction with neuromuscular nAChRs. PMID- 30302405 TI - The transcriptional response of mouse spleen B cells to IL-4: Comparison to the response of human peripheral blood B cells. AB - The Th2 cytokine IL-4 triggers a signaling cascade which activates transcription by STAT6. The goals of the present study are to define the transcriptomic response of mouse spleen B cells (mSBC) to IL-4 used as single stimulus, its specificity compared to human peripheral blood B cells (hPBBC) and to mouse spleen T cells (mSTC), and the pathways affected. Oligonucleotide-based microarrays were performed using two references, the untreated sample and the cells cultured without IL-4, an experimental design which reduces the potential confounding effect of cellular stress during culture. Specificity was addressed by comparing the response of mSBC and our previously published study on hPBBC, of similar design, and a study by other authors on mSTC. We detected an mSBC specific response (including novel genes, e.g., Sertad4, Lifr, Pmepa1, Epcam, Tbxas1; and common genes, e.g., Usp2, Cst7, Grtp1, and Casp6), an hPBBC-specific response (e.g., CCL17, MTCL1, GCSAM, HOMER2, IL2RA), and a common mSBC/hPBBC response (e.g., CISH, NFIL3, SOCS1, VDR, CDH1). In contrast, the mSBC and mSTC responses were largely divergent. Gene set enrichment analysis (GSEA) was applied for the first time to identify the pathways affected. Both in mSBC and hPBBC, IL 4 activated Myc, the transcriptional machinery itself, cell cycle, mitochondria and respiratory chain, ribosome, proteasome and antigen presentation, and Wnt signaling, and inhibited GPCR signaling. However, significant differences were found in histone demethylation, Nod signaling, and Rho signaling, which were downregulated in mSBC, and in chromatin condensation, which was downregulated in hPBBC. These findings may have therapeutic implications for the treatment of allergic diseases and parasitic infections. PMID- 30302406 TI - Prophylactic procedure tract radiotherapy for malignant pleural mesothelioma: A systematic review and meta-analysis. AB - Background and purpose: Malignant pleural mesothelioma (MPM) is an aggressive cancer with a propensity for seeding procedure tracts, leading to symptomatic metastases. There is conflicting evidence on the value of prophylactic procedure tract radiotherapy in reducing tract metastases. We performed a systematic review and meta-analysis to estimate the benefit of radiotherapy in this setting. Materials and methods: Electronic databases were searched to January 1, 2018 for prospective randomized control trials with prophylactic procedure tract radiotherapy as the intervention arm. Pooled odds ratios and 95% confidence intervals were calculated using a random effects model. Study heterogeneity was assessed using the I2 statistic, and publication bias was evaluated by funnel plot and Egger's regression model. Results: Five studies were included for meta analysis. Prophylactic radiotherapy did not have a statistically significant reduction on the risk of procedure site recurrence, with a pooled relative risk of 0.69 (95% CI 0.33-1.43). There was moderate heterogeneity between trials. All trials were assessed as moderate or high risk of bias overall. Conclusion: This systematic review has confirmed that there is no role for prophylactic procedure tract radiotherapy in MPM. In the absence of effective prophylactic procedures, patients need to be monitored closely, and palliative interventions delivered in a timely manner to reduce morbidity associated with procedure tract metastases. PMID- 30302408 TI - Absorption coefficient of carbon dioxide across atmospheric troposphere layer. AB - Absorption coefficient affected by carbon dioxide concentration and optical path length responsible for temperature or global warming across the troposphere layer, which is less than the altitude of 10 km in the atmosphere, is systematically presented in this work. Solar irradiation within a short wavelength range can be absorbed, scattered and transmitted by the atmosphere, and absorbed and reflected by the Earth's surface. Radiative emission in high wavelength ranges from the Earth's surface at low temperature can be absorbed by atmospheric water vapor, carbon dioxide and other gases. Unbalance of radiation thus results in the atmosphere to act as the glass of a greenhouse and increase atmospheric temperature. Even though global warming strongly affects the life of the human being, the cause of global warming is still controversial. This work thus proposes a fundamental and systematical unsteady one-dimensional heat conduction-radiation model together with exponential wide band model to predict absorption coefficients affected by concentration, temperature, optical path lengths and radiation correlated parameters in different bands centered at 15, 4.3, 2.7, and 2 MUm of carbon dioxide across the troposphere layer. It shows that absorption coefficient required for calculating heat transfer is strongly affected by carbon dioxide concentration and optical path length across the troposphere. Relevant values of the latter should be greater than 5,000 m. Absorption coefficients in the band centered at 4.3 MUm subject to a chosen optical path length of 104 m increase from 0.04 m-1 and 0.165 m-1at the tropopause to 0.11 m-1 and 0.44 m-1 at the Earth's surface for carbon dioxide concentrations of 100 and 400 ppm, respectively. A more relevant and detailed temperature profile across the troposphere is presented. PMID- 30302407 TI - Endovascular Repair of Bilateral Carotid Dissection in a Near Hanging Victim. AB - Introduction: There is much debate in the literature regarding the management of blunt cervical carotid injuries. This report describes a case of bilateral carotid artery dissection in the very uncommon case of a near hanging victim and the treatment controversies regarding its management. Report: A 50 year old male patient was admitted after attempted suicide through hanging, having been swiftly rescued by a bystander. On admission, six hours after the event there was no neurological deficit. There was evidence of soft tissue damage related to the rope position, subcutaneous emphysema, and neck swelling. The CT angiogram showed dissection of both common carotid arteries with significant luminal narrowing as well as fracture of the thyroid cartilage; brain injury was excluded. Heparin infusion was started and an endovascular repair with bilateral covered stent placement, requiring coverage of the external carotid artery on the left side, was performed. The vascular procedure was uneventful. The patient was discharged 36 days after the event, on dual antiplatelet drugs and under regular psychiatric and speech therapy care, and is currently alive and well 22 months after surgery with no neurological damage. Discussion: The choice of treatment was not straightforward as there are no guidelines or consensus around its management. In this case, however, an endovascular repair seemed suitable and the result was optimal, with no neurological damage and a good result after 22 months. PMID- 30302409 TI - Aldosterone exerts anti-inflammatory effects on LPS stimulated microglia. AB - Over the last years, studies on microglia cell function in chronic neuro inflammation and neuronal necrosis pointed towards an eminent role of these cells in Multiple Sclerosis, Parkinson's and Alzheimer's Disease. It was found, that microglia cell activity can be stimulated towards a pro- or an anti-inflammatory profile, depending on the stimulating signals. Therefore, investigation of receptors expressed by microglia cells and ligands influencing their activation state is of eminent interest. A receptor found to be expressed by microglia cells is the mineralocorticoid receptor. One of its ligands is Aldosterone, a naturally produced steroid hormone of the adrenal cortex, which mainly induces homeostatic and renal effects. We evaluated if the addition of Aldosterone to LPS stimulated microglia cells changes their inflammatory profile. Therefore, we assessed the levels of nitric oxide (NO), iNOS, IL-6, IL-1beta, TNF-alpha and COX-2 in untreated, LPS-treated and LPS/Aldosterone-treated microglia cells. Furthermore we analyzed p38-MAP-Kinase and NFkappaB signaling within these cells. Our results indicate that the co-stimulation with Aldosterone leads to a decrease of the LPS induced pro-inflammatory effect and thus renders Aldosterone an anti-inflammatory agent in our model system. PMID- 30302411 TI - Lifespan reduction due to neoplasia is nullified by pseudoexfoliation syndrome. AB - Background: Pseudoexfoliation syndrome (PES) is a common eye condition, indicating a risk of various eye diseases. Whether or not PES has extra-ocular physiological or even pathophysiological implications has been a matter of controversy for years. Methods: In total 1888 persons were examined for PES in 1985-86. Of these, 1864 (98.7%) had died and were therefore available for analysis by 01.01.2016. Age and cause(s) of death were recorded. 9 diagnostic groups (cardiovascular disease, cerebrovascular disease, neoplasms, systemic hypertension, diabetes mellitus (DM), chronic obstructive pulmonary disease (COPD), Parkinson's disease, aortic aneurysm (AA), and amyloidosis) based on ICD coding were analyzed for both a possible association between PES and lifespan, as well as PES and specific systemic diseases. Findings: In the cardiovascular group, PES was not associated with an alteration in longevity. The subgroups acute myocardial infarction and other cardiovascular diseases revealed significantly reduced and increased lifespan, respectively, compared to the rest of the population. These deviations were independent of PES. The impact of PES on the neoplasm group showed that PES-positive persons lived 1.81 years (p < 0.001) longer than PES-negative persons. No significant differences in the PES prevalence were found in any of the cause of death diagnostic groups. Interpretations: The present study suggests that lifespan reduction due to neoplasia is nullified by PES, and that this phenomenon is not restricted to one specific neoplasm type. Thus, the paradoxical conclusion emerges that PES provides a lifespan benefit to the patient with a neoplasm. For the remaining diagnostic groups, PES was neither associated with an altered lifespan, nor with any cause of death diagnoses.

AB - Blueberry ash (Elaeocarpus reticulatus Sm.) fruit has potential for human nutrition, but there is limited information on this fruit. This preliminary study aimed to characterise blueberry ash fruit and examine the influence of extraction solvents on its phytochemical and antioxidant properties. Blueberry ash fruit is dark blue in colour and is a stone fruit of small size (7 mm) and light weight (0.2 g). However, it has a high portion of flesh (60% of fruit weight), which is edible and can be a potential source of phytochemicals. Water, ethanol, acetonitrile, acetone, and their combination were tested for extraction of phytochemicals from flesh of this fruit. Water or absolute organic solvent was ineffective for extraction of phenolic compounds from this fruit, but mixtures of water and organic solvents were more effective, and 50% acetone was the most suitable extraction solvent. Extraction with 50% acetone, this fruit was found to contain high levels of total phenolic content, flavonoids, proanthocyanidins, and anthocyanins (104 mg GAE/g, 155 mg RUE/g, 78 mg CE/g, and 119 mg CGE/g, respectively). In addition, this fruit was found to possess potent antioxidant properties. Therefore, this fruit should be further studied for identification of its phenolic compounds and further tested for their biological properties. PMID- 30302410 TI - Xanthine scaffold: scope and potential in drug development. AB - Medicinal plants have been the basis for discovery of various important marketed drugs. Xanthine is one such lead molecule. Xanthines in various forms (caffeine, theophylline, theobromine, etc) are abode in tea, coffee, cocoa, chocolate etc. giving them popular recognition. These compounds are best known for their diverse pharmaceutical applications as cyclic nucleotide phosphodiesterase inhibition, antagonization of adenosine receptor, anti-inflammatory, anti-microbial, anti oxidant and anti-tumor activities. These properties incentivize to use xanthine as scaffold to develop new derivatives. Chemical synthesis contributes greater diversity in xanthine based derivatisation. With highlighting the existing challenges in chemical synthesis, the present review focuses the probable solution to fill existing lacuna. The review summarizes the available knowledge of xanthine based drugs development along with exploring new xanthine led chemical synthesis path for bringing diversification in xanthine based research. The main objective of this review is to explore the immense potential of xanthine as scaffold in drug development. PMID- 30302413 TI - Cost and effectiveness of water, sanitation and hygiene promotion intervention in Ghana: the case of four communities in the Brong Ahafo region. AB - Knowledge of cost and effectiveness of Ghana's main hygiene promotion intervention (HPI), Community-Led Total Sanitation (CLTS), is critical for policy direction. Cost and resultant effect of HPI is examined using a case study of four communities. Surveys were conducted with 300 households, CLTS implementers and relevant agencies during the study period (May 2012 to February 2014). The HPI produced marginal but statistically significant effect (8%, p < 0.001). Improvement in hygiene behaviour was statistically associated with both government investments (p < 0.001) and household investments (p < 0.001). Actual HPI cost is US$ 90 per household: US$ 51 and 39 from government and households respectively. Cost-effectiveness of the HPI is US$ 106.42 per capita of improved hygiene behaviour. PMID- 30302414 TI - Behavioural flexibility of children with Autism Spectrum Disorder on a card sorting task with varying task difficulty. AB - Inflexibility is taken to be a key characteristic of Autism Spectrum Disorder (ASD), although it is unclear which aspect of cognitive functioning is critical in this context. The current study investigated task-switching problems and inflexibility with a group of children with ASD, and a mental-aged matched control group. Participants (n = 50; mean age = 7 years) completed two card sorting tasks, which involved learning to sort by either two or three possible dimensions, and then the sorting rule was switched although the number of dimensions required to sort the cards remained the same. Following the sorting rule change, the ASD group made more errors compared to controls. Errors were also related to task type (two or three dimensions), but this was not found to interact with ASD. If poor performance were solely dependent on executive function (working memory) problems in ASD, then a steeper decrease in performance with an increase in task difficulty for one group, compared to another group, would be expected. The current results suggest that task difficulty is an aspect of importance in set-shifting, but shifting is not differentially affected by this component. PMID- 30302415 TI - Energy utilization in cattle with steady state and non-steady state methods: the importance of thermal neutrality. AB - The efficiency by which animals utilize dietary energy is fundamental to the cost of production for protein of animal origin and to the carbon footprint an animal industry has. Hence, the development of cost effective methodology for determining these measurements of efficiency is important. The objective of the present study was to investigate the use of infrared thermography in a rapid, non steady state method for measuring energy loss in cattle. Data from 241 yearling bulls and steers as well as heifers and mature cows are presented. Infrared images were collected following a 24h feed withdrawal period. The infrared thermal response in these animals was significantly ranked (P < 0.03) with conventional measurements of feed efficiency using residual feed intake values for animals demonstrated to be within a thermal neutral zone. When animals were not within a thermal neutral zone there was no significant ranking. The data suggests that the use of a non-steady state approach using infrared thermography for identifying metabolic efficiency in animals may be a more rapid and less expensive method for identifying differences in energy utilization. The data also demonstrates the importance of maintaining thermal neutrality when measuring metabolic efficiency irrespective of the methodology. PMID- 30302416 TI - The rationale, design, and methods of a randomized, controlled trial to evaluate the efficacy of single-dose dexamethasone in reducing post-embolization syndrome in patients undergoing uterine artery embolization. AB - Background: Uterine artery embolization (UAE) is a minimally invasive technique well established for treating symptomatic uterine fibroids. However, the post procedure recovery for UAE involves a notable inflammatory process in response to ischemia known as post-embolization syndrome (PES). PES encompasses transient leukocytosis, low-grade fever, and can result in readmission of up to 10% of patients. In surgical settings, multiple studies have demonstrated the efficacy of glucocorticoids in reducing inflammation and associated pain. However, this approach has not yet been assessed in predominantly ischemia-driven PES. Methods: This paper describes the protocol of a prospective randomized, double-blind, placebo-controlled, multi-center trial to test the efficacy and safety of single dose dexamethasone on inflammatory responses, pain, nausea, and readmission rates after UAE. The study will enroll pre-menopausal patients between 25 and 55 years (planned enrollment, n = 60) with MRI confirmed symptomatic fibroids. Patients will be randomly allocated into two groups: single-dose intravenous dexamethasone plus standard of care or placebo (normal saline) plus standard of care. Results: The primary endpoint is the patient pain score 4 h following the UAE procedure. Secondary endpoints include pain scores at 7 h and 24 h following UAE; narcotic usage in the first 24 h following UAE; and serum inflammatory markers (white blood cell count, C-reactive protein [CRP], interleukin-6 [IL-6], and cortisol) 24 h after UAE. Conclusion: Given the high incidence of post-procedure pain and difficulty with pain control after uterine artery embolization, results of this trial may directly influence the standard of care in perioperative management of patients undergoing UAE. PMID- 30302417 TI - Reconsideration of sample size and power calculation for overall survival in cancer clinical trials. AB - When designing a cancer clinical trial, it is usual to assume an exponential distribution for a time-to-event outcome such as overall survival (OS). OS is often expressed as the sum of progression-free survival (PFS) and survival post progression (SPP), each of which is assumed to be exponentially distributed. Then, OS does not follow an exponential distribution any more but a gamma or hypo exponential distribution. In this study, we derived a sample size calculation formula for comparing OS between two treatment arms using the log-rank test for OS following a gamma or hypo-exponential distribution. We conducted a simulation study to evaluate the sample size and power calculation based on the gamma or hypo-exponential distribution. We found that we could reduce the sample sizes considerably compared to when assuming an exponential distribution for OS. PMID- 30302418 TI - Case series: Use of stromal lenticule as patch graft. AB - Purpose: To introduce cases of the use, as patch grafts, of stromal lenticules obtained by small incision lenticule extraction (SMILE) surgery. Observations: Case 1 was a 79-year-old man who presented with Ahmed-valve-tube exposure in his left eye. His uncorrected visual acuity (UCVA) was 20/40, best-corrected visual acuity (BCVA) 20/32, and intraocular pressure (IOP) 11 mmHg. He was treated with stromal lenticule patch that had been extracted by SMILE surgery. The patch was positioned underneath of the conjunctiva and sutured to it. At postoperative 8 months, the graft site was well maintained without Ahmed valve-tube exposure, the UCVA was 20/32, BCVA 20/20, and IOP 12 mmHg.Case 2 was a 60-year-old man who presented with Ahmed-valve-tube exposure in his right eye. His UCVA was finger count (FC) 30 cm, his BCVA 20/125, and his IOP 14 mmHg. He was treated with stromal lenticule patch by the same method as employed in case 1. At postoperative 10 days, tube re-exposure and displacement of the Ahmed valve external plate toward the limbus area occurred due to loosening of the anchoring suture. So, we removed the Ahmed valve device, which had been implanted in the supero-temporal area, and performed new Ahmed valve implantation, with a stromal lenticule flap instead of a partial scleral flap, in the supero-nasal area. As of 6 months post-reoperation, the patient was stable, with UCVA 20/200, BCVA 20/40 and IOP 13 mmHg.Case 3 was a 74-year-old man who presented with bullous keratopathy in his right eye, which was blind. Due to severe adhesions, his conjunctiva could not cover the entire cornea. Therefore, we performed a stromal lenticule patch graft with conjunctival advance flap. At postoperative 3 months, the patient's right eye was stable, without displacement or melting of the lenticule graft. Conclusions & importance: It is suggested that the stromal lenticule, with its biocompatibility, sufficient strength, ease of handling and low cost, is a useful patch graft for various therapeutic purposes in the ophthalmic field. PMID- 30302419 TI - Trigeminal hypertrophic interstitial neuropathy presenting as unilateral proptosis, ptosis, tearing, and facial neuralgia. AB - Purpose: To show the utility of MRI and histology in diagnosing rare cases of trigeminal hypertrophic interstitial neuropathy (HIN). Observations: A 57-year old African-American woman presented with a 4-year history of right eye proptosis with tearing, headaches, and worsening right-sided trigeminal neuralgia symptoms and jaw pain. HIV and diabetes tests were negative and thyroid function was normal. MRI identified abnormal thickening of all trigeminal nerve divisions and proptosis secondary to right trigeminal nerve V1 division enlargement. The excised tissue contained S-100 positive Schwann cells in an onion-bulb pattern. Headaches resolved, but proptosis and mild trigeminal neuralgia remained 1 year post-surgery. Conclusions and importance: Trigeminal HIN is very rare, but presents as chronic progressive ocular symptoms with trigeminal neuralgia. Trigeminal nerve hypertrophy is identified by MRI and confirmed histopathologically by detection of Schwann cells in an onion bulb formation.

PMID- 30302420 TI - A Pre-Pregnancy Biomarker Risk Score Improves Prediction of Future Gestational Diabetes. AB - Context: Previous studies have not examined the ability of multiple preconception biomarkers, considered together, to improve prediction of gestational diabetes mellitus (GDM). Objective: To develop a preconception biomarker risk score and assess its association with subsequent GDM. Design: A nested case-control study among a cohort of women with serum collected as part of a health examination (1984 to 1996) and subsequent pregnancy (1984 to 2009). Biomarkers associated with GDM were dichotomized into high/low risk. Setting: Integrated health care system. Participants: Two controls were matched to each GDM case (n = 256 cases) on year and age at examination, age at pregnancy, and number of pregnancies between examination and index pregnancy. Main Outcome Measure: GDM. Results: High risk levels of sex hormone-binding globulin (SHBG; <44.2 nM), glucose (>90 mg/dL), total adiponectin (<7.2 MUg/mL), and homeostasis model assessment estimated insulin resistance (>3.9) were independently associated with 2.34 [95% confidence interval (CI): 1.50, 3.63], 2.03 (95% CI: 1.29, 3.19), 1.83 (95% CI: 1.16, 2.90), and 1.67 (95% CI: 1.07, 2.62) times the odds of GDM and included in the biomarker risk score. For each unit increase in the biomarker risk score, odds of GDM were 1.94 times greater (95% CI: 1.59, 2.36). A biomarker risk score including only SHBG and glucose was sufficient to improve prediction beyond established risk factors (age, race/ethnicity, body mass index, family history of diabetes, previous GDM; area under the curve = 0.73 vs 0.67, P = 0.002). Conclusions: The improved, predictive ability of the biomarker risk score beyond established risk factors suggests clinical use of the biomarker risk score in identifying women at risk for GDM before conception for targeted prevention strategies. PMID- 30302422 TI - Experimental BPA Exposure and Glucose-Stimulated Insulin Response in Adult Men and Women. AB - Context: Human cross-sectional and animal studies have shown an association of the chemical bisphenol A (BPA) with insulin resistance, type 2 diabetes, and other metabolic diseases, but no human experimental study has investigated whether BPA alters insulin/C-peptide secretion. Design: Men and postmenopausal women (without diabetes) were orally administered either the vehicle or a BPA dose of 50 ug/kg body weight, which has been predicted by US regulators (Food and Drug Administration, Environmental Protection Agency) to be the maximum, safe daily oral BPA dose over the lifetime. Insulin response was assessed in two cross over experiments using an oral glucose tolerance test (OGTT; experiment 1) and a hyperglycemic (HG) clamp (experiment 2). Main outcomes were the percentage change of BPA session measures relative to those of the control session. Results: Serum bioactive BPA after experimental exposure was at levels detected in human biomonitoring studies. In the OGTT, a strong positive correlation was found between hemoglobin A1c(HbA1c) and the percentage change in the insulinogenic index (Spearman = 0.92), an indicator of early-phase insulin response, and the equivalent C-peptide index (Pearson = 0.97). In the HG clamp study, focusing on the later-phase insulin response to a stable level of glucose, several measures of insulin and C-peptide appeared suppressed during the BPA session relative to the control session; the change in insulin maximum concentration (Cmax) was negatively correlated with HbA1c and the Cmax of bioactive serum BPA. Conclusions: This exploratory study suggests that BPA exposure to a dose considered safe by US regulators may alter glucose-stimulated insulin response in humans. PMID- 30302424 TI - Early-Onset Diabetes Mellitus in a Patient With a Chromosome 13q34qter Microdeletion Including IRS2. AB - Diabetes mellitus is a multifactorial disease caused by a complex interaction of environmental and genetic factors. Some diabetes mellitus cases, however, are caused by a limited number of mutant genes. Chromosome 13q deletion syndrome, an extremely rare genetic disorder, is caused by structural and functional monosomy of the 13q chromosomal region. We report the case of a 38-year-old Japanese man with Chr13q deletion (a mosaic pattern with heterozygous ring Chr13q) who developed diabetes mellitus. Early-onset diabetes mellitus developed in this patient because of insulin resistance and a lack of adequate insulin secretion. Microarray analysis identified a 4.8-Mb deletion of distal Chr13q, leading to a copy number loss of 40 genes. Among those genes, the insulin receptor substrate 2 gene (IRS2) was the most likely causative candidate for the development of diabetes mellitus in this patient, based on the model of IRS2 knockout mice, which have abnormal glucose and insulin homeostasis closely resembling the human diabetes phenotype. These data provide important information regarding the contribution of a microdeletion of Chr13q, including in IRS2, to the pathogenesis of diabetes mellitus in humans. PMID- 30302425 TI - Experimental pericardial tamponade-translation of a clinical problem to its large animal model. AB - Objectives: Pericardial tamponade is a life-threatening medical emergency, when the hemodynamic consequences of low cardiac output severely disturb the perfusion of the peripheral tissues. Our aim was to design a reliable large animal model to reproduce the clinical scenario with the relevant pathophysiological consequences of pericardial tamponade -induced cardiogenic shock. Material and Methods: Anesthetized Vietnamese mini pigs were used (n=12). Following laparotomy, a cannula was fixed into the pericardium through the diaphragm without thoracotomy. A sham-operated group (n=6) served as control, while in the second group (n=6) pericardial tamponade was induced by intra-pericardial injection of heparinized own blood. Throughout the 60-min pericardial tamponade and the 180-min reperfusion, macro hemodynamics, renal circulation and the mesenteric macro- and micro-circulatory parameters were monitored. Myeloperoxidase activity was measured to detect neutrophil leukocyte accumulation and in vivo histology was performed by confocal laser scanning endomicroscopy to observe the structural changes of the intestinal mucosa. Results: PT increased the central venous pressure, heart rate, and decreased mean arterial pressure. The mesenteric artery flow (from 355.5+/-112.4 vs 182.0+/-59.1 mL/min) and renal arterial flow (from 159.63+/-50.7 vs 35.902+/-27.9 mL//min) and the micro-circulation of the ileum was reduced. The myeloperoxidase activity was elevated (from 3.66+/-1.6 to 7.01+/ 1.44 mU/mg protein) and manifest injury of the ileal mucosa was present. Conclusion: This experimental model suitably mimics the hemodynamics and the pathology of clinical pericardial tamponade situations, and on this basis, it provides an opportunity to study the adverse macro- and micro-circulatory effects and biochemical consequences of human cardiogenic shock. PMID- 30302423 TI - Current Understanding of the Role of Nesfatin-1. AB - Nesfatin-1 was discovered in 2006 and implicated in the regulation of food intake. Subsequently, its widespread central and peripheral distribution gave rise to additional effects. Indeed, a multitude of actions were described, including modulation of gastrointestinal functions, glucose and lipid metabolism, thermogenesis, mediation of anxiety and depression, as well as cardiovascular and reproductive functions. Recent years have witnessed a great increase in our knowledge of these effects and their underlying mechanisms, which will be discussed in the present review. Lastly, gaps in knowledge will be highlighted to foster further studies. PMID- 30302426 TI - The role of co-administration of damage control surgery and vacuum-assisted closure in the treatment of perineal wounds. AB - Perineal wounds caused by high-kinetic-energy shotgun blasts have a high mortality risk because they are often accompanied by injuries of the anus, rectum, genitourinary system, and extremities. Mortality often results from hemorrhage in the early stage and from multiple organ failure caused by sepsis in the late stage. The primary step in the treatment of patients presenting with perineal wound and hemodynamic instability caused by severe hemorrhage is to control hemorrhage and contamination using damage control surgery. After achieving hemodynamic stability, vacuum-assisted closure can be used to reduce the risks of infection and sepsis. In this report, we present a case who had a perineal wound caused by a mine blast and was successfully treated by damage control surgery and vacuum-assisted closure. PMID- 30302427 TI - Pancreatic extragastrointestinal stromal tumor invading the duodenum. AB - Extragastrointestinal stromal tumors that arise in the pancreas are extremely rare and managing them can be difficult, particularly if located in the head of pancreas. This case report aims to contribute to the existing data in the literature regarding extragastrointestinal stromal tumors with rare and unusual locations. We present a 56-year-old man who presented with recurrent mild right upper quadrant abdominal pain. Abdominal computed tomography and magnetic resonance imaging revealed a mass lesion with a diameter of 10 cm localized in the head of pancreas. Pancreaticoduodenectomy with complete tumor excision was performed. He was discharged on the postoperative day 14. Only 15 extragastrointestinal stromal tumors cases have been reported. Of these 15 cases, tumors were located in the head of pancreas in six cases. Here we report the seventh case of pancreatic extragastrointestinal stromal tumor arising in the head of pancreas and also the largest of these seven tumors. PMID- 30302428 TI - Goblet cell carcinoid of the appendix accompanied by adenomatous polyp with high grade dysplasia at the cecum. AB - Goblet cell carcinoid tumor of the appendix is an uncommon neoplasia that shares the histological attributes of both adenocarcinoma and carcinoid tumors. Its prognosis has a more aggressive course than the other known carcinoid tumors. Clinical diagnosis of goblet cell carcinoid is seldom made preoperatively. The most common clinical presentation of goblet cell carcinoid tumor is acute appendicitis. In this study, we report a patient on whom right hemicolectomy was performed because of a cacal sessile polyp with high grade dysplasia; goblet cell carcinoid tumor of the appendix was revealed incidentally during microscopic evaluation of the appendectomy specimen. The patient healed uneventfully and no recurrence was observed after the 12-month follow-up period. Careful microscopic examination of the appendectomy specimen is key for the diagnosis of appendiceal tumors such as goblet cell carcinoid, especially in elderly patients. PMID- 30302429 TI - Cutaneous metastasis of colon adenocarcinoma. AB - Skin metastasis originating from colorectal cancer is a rare entity and usually signifies poor prognosis. We present a case of a 62-year-old male patient who presented with a cutaneous metastatic focus on his forehead after five years of the primary treatment of colon cancer. Complete response from the cutaneous metastasis nodule was achieved with radiotherapy. The patient is still alive and under a second-line palliative chemotherapy regimen because of the multiple liver metastases. It is important for physicians to be aware of skin metastasis in patients with an oncology history. PMID- 30302430 TI - Symptomatic hepatic metastasis of insulinoma 15 years after pancreatic resection. AB - Malignant insulinomas are infrequent endocrine tumors with miscellaneous clinical courses. In this report, we present a rare case of insulinoma that recurred with solitary hepatic metastasis 15 years after the initial resection of the primary tumor from the pancreas. A 20-year-old woman first presented with the symptoms of hypoglycemia in 1996. The diagnosis of pancreatic insulinoma was confirmed by laboratory findings, and the initial surgery had been performed involving complete enucleation of the pancreatic mass. Histopathologically, the tumor was diagnosed as a benign adenoma. After 15 years, the patient experienced symptoms of hypoglycemia again, and laboratory findings and abdominal computed tomography identified a lesion in the liver. Intraoperative ultrasound did not show any lesion in the pancreas, and wedge resection was performed for the hepatic lesion. Postoperative blood glucose levels returned to normal. Histopathologic examination confirmed the diagnosis of liver metastasis of a neuroendocrine tumor. This is the longest interval between primary tumor and the metastasis reported in the literature, for insulinoma. Thus, it should be remembered that long-term follow-up is mandatory for the patients with insulinoma even after resection of the primary tumor. Resection is recommended when a metastatic lesion is observed. PMID- 30302431 TI - A case report of left paraduodenal hernia diagnosed preoperatively and treated laparoscopically. AB - Paraduodenal hernia is a rare congenital anomaly; however, it is the most common cause of internal herniation. Clinical findings are often indeterminate. Computerized tomography is usually diagnostic; however, the diagnosis is often made intra-operatively. Paraduodenal hernia carries a risk of incarceration leading to bowel obstruction and strangulation; therefore, it should be repaired surgically when diagnosed. Here we present a case of left PDH that was diagnosed preoperatively and repaired laparoscopically. PMID- 30302432 TI - Transcervical resection of two parathyroid adenomas located on the anterior mediastinum. AB - The mediastinum is a possible location of ectopic parathyroid adenoma. Most ectopic parathyroid glands in the mediastinum are found in the superior mediastinum within the thymus. In this article, two cases with ectopic mediastinal parathyroid adenomas that were excised via transcervical resection are presented. Preoperative examination of the two cases was performed. Laboratory tests supported hyperparathyroidism. For both patients, the results of radiologic and scintigraphic examinations of the cases were compatible with parathyroid adenoma masses in the anterior mediastinum. Transcervical resection was performed via suprasternal incision through the sternal notch and the posterior wall of the sternum space by blunt dissection with the finger. The soft lesions were removed en bloc in both cases. The parathyroid hormone levels of the two cases decreased dramatically after the operation. Transcervical resection may be an alternative method to major surgery in anterior mediastinal small masses. PMID- 30302433 TI - Idiopathic renal replacement lipomatosis: A diagnostic and therapeutic challenge. AB - Renal replacement lipomatosis is a rare benign renal disorder where the renal parenchyma is replaced by mature fatty tissue. It poses a diagnostic challenge to the clinicians due to an unusual presentation and clinical features. The disease usually presents in middle age with vague pain in the affected flank and variable urological symptoms. Although the condition is preceded by calculus disease or chronic inflammation, as an extremely rare occurrence, it can occur without any pre-existing condition, as in our case. Increasing awareness among the surgeons about the existence of such a condition will help the surgical fraternity to diagnose and manage such cases properly. PMID- 30302434 TI - Perforation of the small intestine caused by enteropathy-associated T cell lymphoma. AB - Enteropathy-associated T cell lymphoma is a rare lymphoma specific to the gastrointestinal system, arising from intraepithelial T lymphocytes, that is often associated with celiac disease. We report a 53-year-old female patient with no previous disease who presented with severe abdominal pain. Physical examination revealed diffuse abdominal tenderness and abdominal guarding and the patient underwent emergency surgery with a diagnosis of acute abdomen. During the operation, a 20-cm mass was found located on Treitz ligament, invading the duodenum and pancreatic head and perforating the jejunum. Histologically, medium sized monomorphic atypical lymphocyte infiltration with dark nucleus and narrow cytoplasm was seen in the layers of mucosa, submucosa, muscular wall, and serosa of the duodenum. The final pathological diagnosis was "enteropathy-associated T cell lymphoma type 2" based on immunohistochemical and serological findings. Based on the World Health Organization 2008 criteria, enteropathy-associated T cell lymphoma has two subtypes. Type 1 enteropathy-associated T cell lymphoma is associated with celiac disease and has HLA DQ2 and HLA DQ8 genotype. Enteropathy associated T cell lymphoma 2 enteropathy-associated T cell lymphoma seldom occurs and is not associated with celiac disease. PMID- 30302436 TI - Editorial: How digital are you? PMID- 30302435 TI - Foreign body: A sewing needle migrating from the gastrointestinal tract to pancreas. AB - Of all ingested foreign bodies, 2.4% comprise of sewing needles. Through perforation of gastrointestinal tract, which occurs in 1% of cases, they can migrate into the liver and pancreas. Foreign bodies in pancreas should be considered in the differential diagnosis of chronic abdominal pain. Computed tomography scans provide valuable information for the localization of the lesion, which guide the surgeon during the operation. Secondary to foreign bodies that migrate to the pancreas, complications with high mortality such as pancreatitis, pseudoaneurysm, and pancreas abscess can be seen. Thus, for this patient group, diagnostic laparoscopy is recommended, considering its advantages of decreased postoperative pain, decreased wound infection, and faster recovery time. Here we present a case of a 23-year-old female patient, from whom an ingested needle that migrated from the back wall of the stomach to the pancreas was extracted by laparoscopic surgery. PMID- 30302437 TI - The full-mouth mock-up: a dynamic diagnostic approach (DDA) to test function and esthetics in complex rehabilitations with increased vertical dimension of occlusion. AB - The mock-up is a diagnostic technique that allows for the intraoral try-in of a prosthetic rehabilitation. Mock-ups facilitate significant improvement in communication with patients by showing them the potential final outcome of the treatment. They also allow for a quick and easy comparison of the pre- and postoperative situations, and permit the clinician to check the functional aspects of the therapy. The purpose of this article is to describe the use of the full-mouth mock-up technique for testing all the functional and esthetic parameters of extensive rehabilitations associated with a VDO increase with completely additive wax-ups. The proposed clinical procedures describe an easy and reversible technique to manage complex prosthetic cases with a more conservative and operator-friendly approach compared with conventional prosthetic therapies, reducing time and costs. All the clinical and technical phases of this approach are described step by step. PMID- 30302438 TI - A patient-calibrated individual wax-up as an essential tool for planning and creating a patient-oriented treatment concept for pathological tooth wear. AB - Tooth wear is generally a physiological process; however, it can also be a pathological condition associated with attrition, abrasion, and erosion processes in which the quantity of tooth loss is atypical for the patient's age. Tooth substance loss often causes functional problems, symptoms of discomfort/pain, and esthetic impairments. Patients presenting this condition frequently need restorative treatment, combined with an increase in the vertical dimension of occlusion (VDO). A diagnostic wax-up (DWU) provides assistance in determining a new occlusal plane and VDO, and is a fundamental tool considering the backward planning involved in the execution of a complex rehabilitation. In cases of severe tooth wear, preventive measures must be taken. Yet, when a restorative intervention is needed, the use of a DWU, in conjunction with a mock-up, helps to achieve a predictable and satisfactory outcome. This article presents a case report of a young female patient with pathological tooth wear, related symptomatology, and esthetic complaints. Initially, a DWU and a diagnostic mock up were created. After esthetic and functional corrections, a second DWU was generated and transferred to the patient's mouth by means of a therapeutic mock up. This mock-up was used as a trial restoration for the pretreatment phase, to evaluate the new VDO/esthetics/function and to guide tooth preparation. Lithium disilicate (LS2) occlusal onlays were used to stabilize the VDO, and anterior LS2 and feldspathic veneers, combined with direct composite restorations, were executed to reach the planned minimally invasive result.

AB - PURPOSE: To determine the most and least attractive smiles from a Brazilian sample and to correlate the anatomical characteristics identified in these smiles. MATERIALS AND METHODS: Orthodontists, dentists, and laypeople assessed the photographs of 86 students (66 women and 20 men), aged between 19 and 30 years, using a visual analog scale (VAS). An evaluator blinded to the results measured the esthetic composition of the eight photographs with the highest and the eight with the lowest ratings for women, and the two with the highest and the two with the lowest ratings for men. The mean and standard deviations were calculated for the descriptive analysis. RESULTS: A total of 42 anatomical smile details were identified and described, obtaining the means of the characteristics. CONCLUSIONS: The following characteristics were observed from the selected most attractive smiles: parallel smile arc, oval-shaped incisors with square-rounded edges, increase of the incisal embrasure and reduction of connector space in distal progression, display of maxillary incisors and minimum display of mandibular teeth, gingival margin of central incisors 0.5 mm coronal to the canines and 0.8 mm apical to the lateral incisors, posterior gingival display of 1.5 mm, less than 20% of buccal corridor and display of 12 teeth, and canines with -2 degrees of inclination. The most attractive smiles also had an absence of asymmetries, diastemas, black spaces, incisal plane inclination, and anterior gingival display.

AB - Following the guidelines of the 'index technique' that were published in this journal in 2015, this article presents the 'digital index technique,' an updated no-prep restorative approach to the management of worn dentition. Patients with minimal, moderate, and severe hard tissue wear can be treated based on the application of minimally invasive or noninvasive adhesive composite restorations on posterior and anterior worn dentition. The technique allows for a purely additive treatment without sacrificing healthy hard tooth tissue. It follows the principles of biodentistry (maximum conservation of healthy tissue), and the reinforcing of residual dental structure. Depending on the severity of the enamel and dentin wear, the number of caries, and the size of the existing restorations, different treatment options can be applied to each tooth: direct and indirect partial restorations or full crowns. It is essential to diagnose and treat tooth surface loss in order to properly restore biomechanics, function, and esthetics by means of adhesive restorations. This article proposes that the update of the index technique through the digital workflow is a fast and conservative approach for the planning and management of a full-mouth adhesive restoration in all cases of light, moderate, and severe worn dentition. The technique is based on a 'copy and-paste' guided approach, stamping composite resin directly onto the tooth surface by means of a transparent index created from a full-mouth digital restorative wax-up, following an initially planned increase in occlusal vertical dimension (OVD) through an esthetic and functional analysis.

AB - PURPOSE: To evaluate and compare light propagation in dental tissues and dental composite restorations using a double-layer build-up technique. MATERIALS AND METHODS: Natural teeth slabs and dental restoration buildups with A2D and B1E colored nanofilled, supra-nanofilled, and microhybrid composites were randomized and equally distributed into four experimental groups (n = 10). Using a spectrophotometer, the samples were irradiated by three wavelengths of lasers: red, green, and blue. A voltmeter recorded the light output signal, and the following optical constants were calculated: absorption (A), transmittance (T), and attenuation (K). The data were analyzed using one-way analysis of variance (ANOVA), followed by post hoc Tukey's test (alpha = 0.05). RESULTS: Absorption results varied according to the laser color and different composites tested. Regardless of the laser wavelength, the supra-nanofilled composite showed greater light transmittance and lower light attenuation compared with the dental tissues, which was the opposite of the nanofilled composite. The microhybrid composite showed no difference in light transmittance or light attenuation compared with the dental tissues. CONCLUSION: Within the limitations of this observational in vitro study, the microhybrid dental composite group had the most similar light propagation pattern compared with natural teeth when using the double-layer build up technique.

AB - PURPOSE: To compare the accuracy of implant impressions using computer-aided impression-making technology and a conventional approach in a standardized setting in vitro, and to verify the effect of implant angulation (40 to 45 degrees) on the accuracy of digital and conventional impression-making procedures. MATERIALS AND METHODS: Four different edentulous mandibular reference models (RMs) were manufactured. Two straight (RM1); four straight (RM2); two straight and two tilted (RM3); and six straight (RM4) dental implants were placed, simulating four different clinical scenarios. The computer-aided impressions (n = 5 for each RM) were made using an intraoral scanner (IOS) (True Definition, 3M ESPE). Polyether (n = 5 for each RM) and vinyl polysiloxane (n = 5 for each RM) impression materials were utilized for the conventional approach. The collected data were analyzed in terms of trueness. The statistical analysis was performed using one-way analysis of variance (ANOVA). RESULTS: The overall differences of interimplant distance, identified in mean values, were statistically significant among the different impression-making groups in RM1, RM3, and RM4. The data analyses of overall interimplant angle deviations yielded statistically significant differences in all four RMs. However, the deviations obtained with both impression-making approaches did not exceed an interimplant distance threshold of 100 um, and an interimplant angle of 0.5 degrees, which seems to be clinically acceptable. CONCLUSION: Within the limits of this in vitro study, the accuracy of the computer-aided and conventional impression-making approaches for straight and tilted dental implants was comparable, and might be clinically considered for full-arch, multiple-implant restorations. However, further clinical studies are required to verify the feasibility of different IOSs (with and without scanning powder application), different implant systems, and multiple implant configurations.

AB - Since the demonstration of the unique properties of single-layer graphene and transition metal dichalcogenides (TMDs), research on two-dimensional (2D) materials has become one of the hottest topics, with the family of 2D materials quickly expanding. This expansion is mainly attributable to the development of new synthesis methods to create new materials. This review will summarize and critically analyze topochemical synthesis methods for synthesizing novel 2D materials. For example, the emerging family of 2D transition metal carbides, nitrides and carbonitrides (MXenes) are synthesized primarily by selective etching of "A" (metal) elements from MAX phases. Another 2D material, hydrogenated germanene is produced by selective etching of calcium digermanide (CaGe2). The topochemical transformation of one dichalcogenide into another and 2D oxides into 2D carbides or nitrides have attracted great attention because materials with many useful and diverse properties can be obtained by these methods. Topochemical synthesis methods provide alternative ways of synthesizing 2D materials not requiring van der Waals bonded solid precursors or vapor phase deposition, but they have not been comprehensively reviewed. In this review, we describe common principles of topochemical synthesis of 2D materials, explain synthesis mechanisms and offer an outlook for future research.

AB - Propeller-shaped pyridyl-enolato-catecholate/-salicyl spiroborates (Sborepy1-6) were synthesized. The complexes Sborepy3-6 show weak emission in fluid solution and aggregation-induced emission enhancement in the aggregation state with large Stokes shifts of 4025-5237 cm-1. Moreover, intense solid-state emissions with high Phif ranging from 25% to 37% were observed for Sborepy3-6 owing to the weak intermolecular interactions in their solid-state. The AIE and intense solid-state emission have been revealed via the X-ray diffraction analysis and theoretical calculations. Furthermore, the solvatochromism in the solution state and the potential application as a fluorescent acidic vapour sensor in the solid state of Sborepy3 and Sborepy6 were also demonstrated.

AB - A Tb(iii)-based coordination polymer (polyTb) was synthesized by complexation of Tb(NO3)3.(6H2O) and 4',4''''-[1,1'-biphenyl]-4,4'-diylbis[6,6'' bis(ethoxycarbonyl)2':6',2''-terpyridine](L). The polymer structure was determined by Job's plots, DFT calculation, and X-ray absorption fine structure (XAFS) measurement. Job's plots indicated that the mole ratio (Tb ion : L) is 1 : 1. The optimized model structures suggested a La model: the LaN6(O[double bond, length as m-dash]C)2 model. The bond distances of La-O and La-N are ~2.80 A and 2.60 A, respectively. The EXAFS fitting indicated that the bond distances of Tb-O and Tb-N are 2.65 A and 2.95 A, respectively. polyTb shows field-induced magnetic relaxation in the solid and solution state. The luminescence of polyTb, originating from an f-f transition, was observed (phi = 6.9%). polyTb formed a porous structure on a Si substrate, whereas a fibrous complex structure was formed on glass. polyTb chains are orientated on glass, which were determined by XRD.

AB - Dynamic deposition of ZnO nanostructures with varying morphologies (nanorods, nanocones, nanopencils, nanosheets, etc.), diameters, lengths and aerial densities on ITO-PET substrates has been achieved using a continuous flow microreactor in which we maintained a homeostatic zinc concentration and varied the other reactants' concentrations.

AB - Ni2P nanoparticles anchored on MOF-derived Co,N-doped porous carbon polyhedrons (Ni2P/CoN-PCP) were successfully prepared. The Ni2P/CoN-PCP catalyst shows excellent trifunctional electrocatalytic performances for the oxygen reduction, oxygen evolution, and hydrogen evolution reactions, attributed to the synergistic effect between active Ni2P nanoparticles and the CoN-PCP support with rich Co-Nx centres, abundant defects and high conductivity. This work demonstrates a superior low-cost electrocatalyst for potential application in fuel cells and water splitting devices.

AB - The double chloride-bridged dimer of a dinuclear dysprosium(iii) single-molecule magnet (SMM) was successfully isolated by assembling centrosymmetric dinuclear Dy2 SMMs. Such structural transformation involves the generation and cleavage of chloride bridges and leads to consecutive transformations of one- and two-step slow relaxation of magnetization. PMID- 30302449 TI - From double-shelled grids to supramolecular frameworks. AB - Structurally unique double-shelled 4f and 3d-4f supramolecular grids were constructed and assembled into 3D hydrogen-bonded organic frameworks (HOFs), with the 3d-4f heterometallic HOF showing single-molecule magnet (SMM) behaviour. PMID- 30302450 TI - Fully quantum calculation of the second and third virial coefficients of water and its isotopologues from ab initio potentials. AB - Path-Integral Monte Carlo methods were applied to calculate the second, B(T), and the third, C(T), virial coefficients for water. A fully quantum approach and state-of-the-art flexible-monomer pair and three-body potentials were used. Flexible-monomer potentials allow calculations for any isotopologue; we performed calculations for both H2O and D2O. For B(T) of H2O, the quantum effect contributes 25% of the value at 300 K and is not entirely negligible even at 1000 K, in accordance with recent literature findings. The effect of monomer flexibility, while not as large as some claims in the literature, is significant compared to the experimental uncertainty. It is of opposite sign to the quantum effect, smaller in magnitude than the latter below 500 K, and varies from 2% at 300 K to 10% at 700 K. When monomer flexibility is accounted for, results from the CCpol-8sf pair potential are in excellent agreement with the available experimental data and provide reliable B(T) values at temperatures outside the range of experimental data. The flexible-monomer MB-pol pair potential yields B(T) values that are slightly too high compared to experiment. For C(T), our calculations confirm earlier findings that the use of three-body potential is necessary for meaningful predictions. However, due to various uncertainties of the potentials used, especially the three-body ones, we were not able to establish benchmark values of C(T), although our results are in qualitative agreement with available experimental data. The quantum effect, never before included for water, reduces the magnitude of the classical value for H2O by a factor of 2.5 at 300 K and is not entirely negligible even at 1000 K.

AB - Symmetric and asymmetric beta-diketiminato rare-earth metal dialkyl complexes L1Ln(CH2SiMe3)2(THF) (L1 = (2,6-Et2C6H3)NC(Me)CHC(Me)N(2,6-Et2C6H3), Ln = Y (1a), Lu (1b)) and L2Ln(CH2SiMe3)2(THF) (L2 = (2,6-iPr2C6H3)NC(Me)CHC(Me)N(C6H5), Ln = Y (2a), Lu (2b)) have been synthesized by the reaction of the precursor Ln(CH2SiMe3)3(THF)2 with the corresponding pro-ligands (HL1 and HL2) in good yield. These complexes promote the polymerization of 2-vinylpyridine (2-VP) to produce isotactic-biased poly(2-vinylpyridine) (P2VP) (mm: 40%) in quantitative yield. The in situ generated cationic species with the addition of borate ([Ph3C][B(C6F5)4], [PhNHMe2][B(C6F5)4]) prior to the polymerization display distinct results, and the symmetric ones afford perfectly isotactic P2VP with an mm value up to 99%, whilst the asymmetric ones produce atactic P2VP (mm: 26%). The 1H NMR spectrum and MALDI-TOF mass analysis of an oligomer prepared with 1a/[Ph3C][B(C6F5)4] indicate that the polymerization is initiated by coordination insertion of 2-VP into the Y-CH2SiMe3 bond of the in situ generated cationic species.

PMID- 30302453 TI - A new salicylaldehyde-based azo dye and its two lanthanide(iii) complexes displaying slow magnetic relaxation. AB - A new salicylaldehyde-based azo dye 5-azotriazolyl-3-methoxysalicylaldehyde (H2TMSA) and its two Ln3+ complexes {[Ln(HTMSA)3(H2O)2][Ln(HTMSA)3(DMF)(H2O)]}.15H2O (Ln = Dy(1) and Tb(2)) have been synthesized and characterized by IR, Raman, 1H NMR and single-crystal X-ray diffraction techniques. H2TMSA shows an azo form in acidic (pH < 5.05) and strong basic (pH > 12.41) conditions, and a pH-dependent azo-hydrazone tautomerism in the range of pH 5.05 to 12.41, which is demonstrated by the time-dependent density functional theory (TD-DFT) calculations. Single-crystal X-ray diffraction reveals that 1 and 2 are isostructural complexes in which the Ln3+ ions are surrounded by six oxygen atoms from three dichelate HTMSA- ligands and two oxygen atoms from two solvent molecules forming a distorted square-antiprismatic geometry. Complex 1 shows distinct slow magnetic relaxation under a zero dc field, while 2 displays field-induced slow magnetic relaxation. Ab initio calculations were performed on the two complexes to understand their magnetic anisotropy and their different magnetic dynamics.

AB - The trinuclear copper(ii) complex [Cu3(saltag)(py)6]ClO4 (H5saltag = tris(2 hydroxybenzylidene)triaminoguanidine) was synthesized and characterized by experimental as well as theoretical methods. This complex exhibits a strong antiferromagnetic coupling (J = -298 cm-1) between the copper(ii) ions, mediated by the N-N diazine bridges of the tritopic ligand, leading to a spin-frustrated system. This compound shows a T2 coherence time of 340 ns in frozen pyridine solution, which extends to 591 ns by changing the solvent to pyridine-d5. Hence, the presented compound is a promising candidate as a building block for molecular spintronics. PMID- 30302455 TI - A simple chemical solution synthesis of nanowire-assembled hierarchical CuO microspheres with enhanced photochemical properties. AB - Hierarchical micro/nanostructures manifest attractive prospects for photocatalytic application. Nevertheless, large-scale hierarchical micro/nanostructures for industrial application with facile, low-cost and eco friendly routes remain difficult. Herein, nanowire-assembled hierarchical CuO microspheres (HCMAW) are synthesized for the first time by CO32- ions induced synthesis route. The time-dependent SEM images reveal that the growth mechanism for HCMAW is the well-known Ostwald ripening with self-assembly. The specific surface area of the HCMAW is 7.265 m2 g-1, which is higher than that of hierarchical CuO microspheres assembled with nanosheets (HCMAS) (4.952 m2 g-1) prepared by direct self-assembly scheme without the introduction of CO32- ions. Meanwhile, the HCMAW possess strong light absorption around a broadband wavelength from 300 nm to 800 nm. As a result, the photodegradation activity test demonstrates that the HCMAW shows the degradation efficiency of 98.8% for rhodamine B (RhB) under white light irradiation for 30 min in the presence of H2O2 higher than those of HCMAS (66.3%) and commercial CuO (48.3%) under the same condition, which is one of the highest reported till date related to CuO nanomaterials for the degradation of RhB. The novel HCMAW synthesized by the ion induced protocol is worth being generalized to more assembled hierarchical micro/nanostructures for versatile applications.

AB - Candida albicans is an opportunistic human pathogen that can become virulent due to its ability to switch from a benign yeast to virulent hyphae phenotype. The emergence of C. albicans resistant to commonly used antifungal agents has necessitated the development of innovative treatments, which must be accompanied by an understanding of the molecular changes that occur during the phenotypic shift. For this purpose, Fourier transform mid-infrared spectroscopy in attenuated total reflectance mode (FT-mIR-ATR) was applied to monitor the structural and compositional changes in C. albicans during the yeast-to-hyphae transition. FT-mIR-ATR measurements were completed on the whole cell of C. albicans (SC5314) during hyphal formation induced by N-acetylglucosamine at 0, 1, 2, 3, 6 and 24 h. Principal component analysis separated the FT-mIR-ATR spectra into four groups that were aligned with the morphological changes captured by microscopic imaging. Spectral signatures indicating the structural and compositional modifications during the transition were identified mainly in the fatty acid region (3100-2800 cm-1), the protein and peptide region (1800-1500 cm 1), the mixed region (1500-1200 cm-1) and the polysaccharide region (1200-900 cm 1). A spectral fingerprint of the transition via a heat map was generated based on the peak shift in position. Quantitative evaluation of the spectra by curve fitting further revealed the dynamics of the cell's main components during the transition. This work provides valuable structural and functional information on the C. albicans phenotypic transition to hyphae, which has diagnostic implications. PMID- 30302457 TI - Slow-targeted release of a ruthenium anticancer agent from vitamin B12 functionalized marine diatom microalgae. AB - Herein we report the synthesis of a new biomaterial designed for targeted delivery of poorly water-soluble inorganic anticancer drugs, with a focus on colorectal cancer. Diatomaceous earth microparticles derived from marine microalgae were coated with vitamin B12 (cyanocobalamin) as a tumor targeting agent and loaded with the well-known anticancer agents cisplatin, 5-fluorouracil (5-FU), and a tris-tetraethyl[2,2'-bipyridine]-4,4'-diamine-ruthenium(ii) complex. The successful functionalization of the biomaterial was demonstrated by different analytical techniques and by synthesizing an organometallic fluorescein analogue of cyanocobalamin detectable by confocal laser scanning microscopy. The drug releasing properties were evaluated for all three species. We found that while cisplatin and 5-FU are rapidly lost from the material, the ruthenium complex showed an unprecedented release profile, being retained in the material up to 5 days in aqueous media but readily released in lipophilic environments as in the cell membrane. The increased adherence of the B12 coated diatoms to colorectal cancer cell line HT-29 and breast cancer cell line MCF-7 was demonstrated in vitro. In both cases, the adherence of the B12 modified diatoms was at least 3 times higher than that of the unmodified ones and was correlated with the increased transcobalamin II (TC(II)) and transcobalamin II receptor (TC(II)-R) expression of the targeted tissue. Our results suggest that this type of B12 modified diatoms could be a promising tool to achieve targeted delivery of water insoluble inorganic complexes to tumor tissues by acting as a micro-shuttle interacting with the sites of interest before delivering the drug in the vicinity of the tumor tissue.

PMID- 30302460 TI - A modular assembly pH-sensitive charge reversal siRNA delivery system. AB - Cationic lipids and polymers are the most common non-viral vectors for siRNA delivery; however, their intense positively charged character may give rise to serum-triggered aggregation, immune activation, inflammation stimulation and grievous toxicity. An ocean of charge shielding strategies is exploited, but the currently available siRNA delivery systems still remain ungratified and deficient. Herein, we developed a facile modular assembly strategy for a pH sensitive charge reversal siRNA delivery system (PC), which can be easily obtained by adjusting the ratios of positively and negatively charged modules. This PC is electronegative at neutral pH and reverses to electropositive at an acidic pH value with increased tumor cellular uptake. Also, the PC can promote efficient intracellular release and cytoplasmic distribution of siRNA, due to its fusogenic potential with the lysosome membrane. Moreover, the PC loaded with siRNA targeting survivin mRNA (cpusiRNA2) specifically down-regulated the expression of survivin, possessing remarkable tumor therapeutic efficacy in vitro and in vivo. Accordingly, this handy and effective assembly strategy would provide a promising platform for the design of siRNA delivery systems in cancer therapy. PMID- 30302465 TI - Ubiquinol is superior to ubiquinone to enhance Coenzyme Q10 status in older men. AB - Coenzyme Q10 (CoQ10) exerts its functions in the body through the ability of its benzoquinone head group to accept and donate electrons. The primary functions are to relay electrons for ATP production in the electron transport chain and to act as an important lipophilic antioxidant. Ubiquinone, the oxidized form of CoQ10, is commonly formulated in commercial supplements, and it must be reduced to ubiquinol to exert CoQ10's functions after consumption. Thus, we aimed to examine whether as compared to ubiquinone, ubiquinol would be more effective to enhance the CoQ10 status in older men. We conducted a double-blind, randomized, crossover trial with two 2-week intervention phases and a 2-week washout between crossovers. Ten eligible older men were randomized to consume either the ubiquinol or ubiquinone supplement at a dose of 200 mg d-1 with one of the main meals. A total of 4 blood samples were collected after an overnight fast for the determination of ubiquinone and ubiquinol in plasma and PBMC and the assessment of FRAP, total thiol, and malondialdehyde (MDA) in plasma and ATP in PBMC. After 2 weeks of the supplementation, the ubiquinol supplement significantly increased plasma ubiquinone 1.7 fold from 0.2 to 0.6 MUmol L-1 and total CoQ10 (the sum of 2 forms) 1.5 fold from 1.3 to 3.4 MUmol L-1 (p < 0.05) and tended to increase the plasma ubiquinol status 1.5 fold from 1.1 to 2.8 MUmol L-1, but did not alter the ratio of ubiquinol to total CoQ10. The ubiquinone supplement insignificantly increases plasma ubiquinol, ubiquinone, and total CoQ10 and did not affect the ratio. Of 10 subjects, six were more responsive to the ubiquinol supplement and 2 were more so to the ubiquinone. The supplementation of both CoQ10 forms did not alter the CoQ10 status in PBMC. FRAP, total thiol, and MDA in plasma and ATP in PBMC were not changed during the intervention. The significant increase in plasma CoQ10 status observed after the 2-week supplementation suggested that ubiquinol appeared to be a better supplemental form to enhance the CoQ10 status than ubiquinone in older men. Neither ubiquinol nor ubiquinone supplement affected the measured biomarkers of oxidative stress.

AB - A terminal nickel hydroxide complex (PN3P)Ni(OH) (3) bearing the 2nd generation phosphorus-nitrogen PN3P-pincer ligand has been synthesized and structurally characterized. As a nucleophile, 3 reacts with CO to afford the hydroxycarbonyl complex 4, (PN3P)Ni(COOH). 3 can also activate CO2 and CS2 to produce nickel bicarbonate (PN3P)Ni(OCOOH) (5) and bimetallic dithiocarbonate [(PN3P)NiS]2CO (6) respectively, as well as to promote aryl isocyanate and isothiocyanate insertion into the Ni-OH bond to give the corresponding (PN3P)NiEC(O)NHAr complexes (E = O, 7; E = S, 8). In addition, 3 catalyzes the nitrile hydration to various amides with well-defined intermediates (PN3P)Ni-NHC(O)R (R = Me, 9; R = Ph, 10).

AB - Inter-ligand van der Waals forces play a key role in the synthesis of different ZIF types.

It exhibits high CO2 uptake and stepwise adsorption of light hydrocarbons with potential applications in ethane/ethylene separation. PMID- 30302468 TI - Flexible construction of cellulose photonic crystal optical sensing nano materials detecting organic solvents. AB - We developed a simple and efficient method to construct 3D and 2D opal and inverse opal cellulose photonic crystal films (CPCF) by embedding 3D or 2D polymethyl methacrylate (PMMA) colloidal arrays into carboxymethyl cellulose (CMC), respectively. The morphology and optical performance of CPCFs were characterized by SEM, diffraction spectra, Debye rings, and structural color. The brilliant structural colors of CPCFs are visible to the eye in the entire visible spectrum, and can be tuned by changing the particle diameters or the pore sizes. Attributed to decreased particle spacing and lower average refractive index caused by air spheres instead of polymer spheres, the stopbands of the inverse opal CPCFs blue-shifted. To the contrary, the particle spacing of 2D inverse opal CPCFs increased due to the losing of the connection force of 2D arrays, along with decreasing of Debye ring diameters. By alternately being exposed to organic solvents of methanol, acetonitrile, butanol, dioxane, and carbon tetrachloride, the 3D inverse opal CPCFs displayed an excellent sensing performance with instantaneously reversible color changes from violet to red. Their high stability and flexibility, efficient visual detection, and wide range of analytes promises a new opportunity for optical switching and sensing applications. PMID- 30302469 TI - Gel-based cell manipulation method for isolation and genotyping of single adherent cells. AB - Genetic analysis of single-cells is widely recognized as a powerful tool for understanding cellular heterogeneity and obtaining genetic information from rare populations. Recently, many kinds of single-cell isolation systems have been developed to facilitate single-cell genetic analysis. However, these systems mainly target non-adherent cells or cells in a cell suspension. Thus, it is still challenging to isolate single-adherent cells of interest from a culture dish using a microscope. We had previously developed a single-cell isolation technique termed "gel-based cell manipulation" (GCM). In GCM, single-cells could be visualized by photopolymerizable-hydrogel encapsulation that made it easier to isolate the single-cells. In this study, GCM-based isolation of single-adherent cancer cells from a culture dish was demonstrated. Single-adherent cells were encapsulated in a photopolymerizable hydrogel using a microscope and isolated with high efficiency. Furthermore, whole genome amplification and sequencing for the isolated single-adherent cell could be achieved. We propose that the GCM based approach demonstrated in this study has the potential for efficient analysis of single-adherent cells at the genetic level.

The present results show the applicability of scanning dielectric microscopy to nanoscale filamentous protein complexes and to general 3D macromolecular protein geometries, thus opening new avenues to study the relationship between the dielectric response and protein structure and function.

Herein, we successfully synthesized Au NP decorated poly(styrene-co-(generation 3 carbosilane-thioether vinyl-terminated dendrimer)) (P(st-co-G3Vi)) microspheres via in situ reduction of Au ions based on the strong coordination between the Au ions and the sulfur atom in G3Vi dendrimers. These composite Au-doped microspheres demonstrate a bumpy surface topography, which gives rise to a higher hydrophobicity and could effectively suppress the formation of an ubiquitous coffee-ring during the drying process of a colloidal suspension. More importantly, layer-controllable PCs were constructed with Au-doped microspheres by combining the Langmuir-Blodgett method with a layer-by-layer stacking strategy. By manipulating the stacking layers and diameters of microspheres, multifarious PCs with different photonic band gaps and reflection intensities were obtained, which can serve as an effective substrate for amplified quantum dot fluorescence. Further investigation reveals that fluorescence could be significantly pronounced by five-layer PCs. This work offers a facile and reproducible strategy to prepare Au NP incorporated PCs by in situ synthesis of Au NPs within dendrimer-functionalized microspheres, resulting in an enhancement of quantum dot fluorescence, which will lead to promising applications in energy saving optoelectronic devices.

Our study aims to assess whether a saponin-enriched extract from the leaves of Boussingaultia gracilis (SBG) could attenuate obesity and its related metabolic disorders in mice and to explore the potential mechanism of this effect. Three-week old male mice were fed with a HFD for 7 weeks followed by a 10-week period in which the mice were supplemented with distilled water or SBG (250 mg per kg bodyweight). We demonstrated that SBG supplementation for 10 weeks mitigated obesity and its complications in diet-induced obesity (DIO) mice, such as reducing the hepatic damage underlying steatosis, modulating lipid metabolism, enhancing adipocyte thermogenesis, restoring insulin sensitivity and glucose homeostasis, and alleviating inflammation status. Finally, we established an untargeted metabolomics approach based on UPLC-MS to profile the metabolic changes in liver tissue and thereby discovered novel potential biomarkers to clarify the mechanisms of action of SBG in treating a mouse model of DIO. Thirty-nine potential biomarkers and five metabolic pathways contributing to the beneficial effect of SBG were discovered and identified.

AB - Two-dimensional (2D) molybdenum nitride (MoN) nanosheets are promising anode materials for improved lithium-ion batteries. However, the reported synthesis methods of MoN generally rely on high-temperature and complex procedures with low cost efficiency. Herein, we report a facile one-pot synthesis of 2D MoN nanosheets at a low temperature of 400 degrees C via a solid-state reaction of molybdenum disulfide, sulfur and sodium amide in an autoclave. When employed as the anode material for lithium ion batteries, the as-developed MoN electrode exhibits outstanding cyclability with a high capacity retention of 898 mA h g-1 over 400 cycles at a current rate of 200 mA g-1 as well as a superb rate capability with a capacity of 505 mA h g-1 at a high rate up to 2 A g-1. The excellent lithium storage performance of the MoN electrode is attributed to its advantageously high conductivity and unique 2D nanostructure. PMID- 30302476 TI - Porous Co3O4 nanoplates with pH-switchable peroxidase- and catalase-like activity. AB - Porous Co3O4 nanoplates were synthesized via a soft template method. By using amphiphilic block copolymer F127 colloids as the pore producer, porous Co(OH)2 nanoplates were prepared. After the annealing procedure, the obtained Co3O4 reserved the hexagonal shape and a similar size to the Co(OH)2 precursor. The as prepared porous Co3O4 nanoplates named Co3O4-F simultaneously possessed peroxidase and catalase mimetic activities. Interestingly, these two kinds of mimetic enzyme activities could be switched by pH. Meanwhile, temperature and the concentrations of Co3O4-F had a significant effect on the switch pH and the dual enzyme mimetic catalytic ability. Moreover, Co3O4-F exhibited good peroxidase like catalytic activity even in the neutral pH system, providing a new strategy for one-step analysis of glucose. A novel one-step colorimetric glucose biosensor was fabricated based on the Co3O4-F nanozyme, making the operation of detection simpler and easier. PMID- 30302477 TI - Bioactive properties and phytochemical assessment of Bacupari-anao (Garcinia brasiliensis Mart.) leaves native to Rondonia, Brazil. AB - Leaf fractions of Garcinia brasiliensis were evaluated concerning their antioxidant, antimicrobial, anti-inflammatory and cytotoxic properties, and the most active fraction was then fully characterized regarding its phenolic composition using HPLC-DAD-ESI/MSn. The ethyl acetate fraction from partitioning of the methanolic leaf extract revealed a strong antioxidant activity that was comparable to Trolox, the positive control. This fraction was also able to show a significant antimicrobial activity against Gram-positive and Gram-negative bacteria and the fungus Candida albicans. However, the dichloromethane fraction was found to present the highest anti-inflammatory (83 +/- 9 MUg mL-1) and cytotoxic activities, thus presenting slight toxicity using a non-tumor cell line. Regarding the phenolic profile, the ethyl acetate fraction presented twelve flavonoids, with morelloflavone-7''-O-glucoside (52.1 +/- 0.4 mg g-1) and gardinia biflavonoid 2a glucoside (27.5 +/- 0.2 mg g-1) being the major compounds identified. These results indicate that leaves of G. brasiliensis might be a potential source of natural biomolecules for pharmaceutical and medicinal applications. PMID- 30302479 TI - High efficiency focusing vortex generation and detection with polarization insensitive dielectric metasurfaces. AB - The optical vortex beam with an orbital angular momentum, featuring a doughnut intensity distribution and a helically structured wavefront, has received extensive attention due to its applications in nanoparticle manipulation and optical communications. In this paper, we propose high-efficiency polarization independent vortex beam generators which are capable of transforming the arbitrarily polarized plane wave into a focusing optical vortex beam and an abruptly focusing airy vortex beam. Besides, based on holographic metasurfaces, we provide a general design scheme for detecting the topological charges. With such a design strategy, multichannel topological charge resolved devices are demonstrated, which successfully implement the detection of the topological charges from -2 to 2. The metasurfaces designed with a simple and effective method in light manipulation promise photonic applications in secure communications and other related areas. PMID- 30302480 TI - Are zinc clusters really amorphous? A detailed protocol for locating global minimum structures of clusters. AB - We report the results of a conjoint experimental/theoretical effort to assess the structures of free-standing zinc clusters with up to 73 atoms. Experiment provides photoemission spectra for ZnN- cluster anions, to be used as fingerprints in structural assessment, as well as mass spectra for both anion and cation clusters. Theory provides both a detailed description of a novel protocol to locate global minimum structures of clusters in an efficient and reliable way, and its specific application to neutral and charged zinc clusters. Our methodology is based on the well-known hybrid EP-DFT (empirical potential-density functional theory) approach, in which the approximate potential energy surface generated by an empirical Gupta potential is first sampled with unbiased basin hopping simulations, and then a selection of the isomers so identified is re optimized at a first-principles DFT level. The novelty introduced in our paper is a simple but efficient new recipe to obtain the best possible EP parameters for a given cluster system, with which the first step of the EP-DFT method is to be performed. Our method is able to reproduce experimental measurements at an excellent level for most cluster sizes, implying its ability to locate the true global minimum structures; meanwhile, if exactly the same method is applied based on the existing Gupta potential (fitted to bulk properties), it leads to wrong predicted structures with energies between 1 and 2 eV above the correct ones. Opposite to what was claimed in the past, our work unequivocally demonstrates that Zn clusters are not amorphous, and they rather adopt high symmetry structures for most sizes. We show that Zn clusters have a number of exotic, unprecedented structural and electronic properties which are not expected for clusters of a metallic element, and describe them in detail. PMID- 30302482 TI - DNA microarray analysis using a smartphone to detect the BRCA-1 gene. AB - DNA microarrays are used to examine changes in gene expression of a large number of genes simultaneously by fluorescent labeling of complementary DNAs (cDNAs). The major bottleneck in implementing microarray technology in resource-limited settings lies in the detection instrument used for generating images of spotted oligonucleotides post-hybridization. While various methods such as a lateral flow assay have been presented to accomplish point-of-care disease detection, there is no simple and effective instrument available to gather spot images maintaining the standard microarray procedures. Nanotechnology based sensors connected with a portable smartphone readout system have the potential to be implemented in microarray technology. Here, we describe a portable fluorescence microarray based imaging system connected to a smartphone for detecting breast cancer gene expression (BRCA-1) from exon 11. This is based on the interactive binding of probe DNA to Cy3-target DNA. A paper-based microfluidics approach was used to demonstrate the DNA hybridization assay. The imaging principles of the assembled device named "FluoroZen" are similar to those of a fluorescence microscope. It uses two light spectrum filters, one to excite the fluorescent dye and the other to capture the emission spectrum. The images were acquired by using CCD cameras from FluoroZen. The smartphone integrated paper microfluidics platform presented here could be translated into clinical settings to perform point-of-care testing. PMID- 30302483 TI - Properties and prospects for rhenium(i) tricarbonyl N-heterocyclic carbene complexes. AB - Re(i) complexes bound to pi-conjugated bidentate N-heterocyclic carbene ligands with formulation Re(CO)3(N^NHC)L (where N^NHC represents an imidazole or benzimidazole carbene ligand conjugated to a N-based heterocycle such as pyridine, pyrimidine, quinoline or quinoxaline) are a relatively new class of complexes belonging to the archetypal family of well known luminescent Re(CO)3(diim)X species (where diim is a conjugated diimine ligand and X is a halogen anion). The complexes Re(CO)3(N^NHC)L are characterised by blue-shifted emission compared to Re(CO)3(diim)X, but with shorter excited state lifetime decays and lower quantum yields, in contrast to trends expected by the energy gap law. Detailed investigations elucidated that these complexes are photochemically active and undergo ligand exchange reactions when excited to their lowest metal to-ligand charge transfer excited states. This mechanism is entirely different from previously known mechanisms of photoactivated ligand substitution reactions in Re(i) tricarbonyl complexes. Therefore, the species Re(CO)3(N^NHC)L represent a new and unique class of photoactive Re(i) complexes. This feature article illustrates the research effort dedicated to the design and synthesis of Re(CO)3(N^NHC)L complexes and the elucidation of their photophysical and photochemical behaviour by means of a variety of spectroscopic techniques. Furthermore, for their unique characteristics, these new complexes have demonstrated potential value in several applications including catalysis, diagnosis and therapy. These studies will also be illustrated herein. PMID- 30302484 TI - pi-Conjugated thiolate amplified spectrophotometry nitrite assay with improved sensitivity and accuracy.

PMID- 30302485 TI - Linear heterostructured Ni2Si/Si nanowires with abrupt interfaces synthesised in solution. AB - Herein, we report a novel approach to form axial heterostructure nanowires composed of linearly distinct Ni silicide (Ni2Si) and Si segments via a one-pot solution synthesis method. Initially, Si nanowires are grown using Au seeds deposited on a Ni substrate with the Si delivery in the solution phase using a liquid phenylsilane precursor. Ni silicide then forms axially along the wires through progressive Ni diffusion from the growth substrate, with a distinct transition between the silicide and pure Si segments. The interfacial abruptness and chemical composition of the heterostructure nanowires was analysed through transmission electron microscopy, electron diffraction, energy dispersive X-ray spectroscopy, aberration corrected scanning transmission electron microscopy and atomically resolved electron energy loss spectroscopy. The method represents a versatile approach for the formation of complex axial NW heterostructures and could be extended to other metal silicide or analogous metal germanide systems. PMID- 30302486 TI - Fluid-permeable enzymatic lactate sensors for micro-volume specimen. AB - Sensing of lactate in perspiration provides a way to monitor health and control exercise. The volume of perspiration is miniscule, and the efficient collection of perspiration is desired for its effective sensing. We developed mesh-type enzymatic electrodes fabricated on textile meshes and integrated the meshes into an enzymatic biofuel cell. We tested them as self-powered lactate sensors for a small volume of lactate solution. A fluid-permeable enzymatic anode was fabricated based on an insulating textile mesh that was coated with carbon nanotubes (CNTs) and lactate oxidase. The anode was further coated with polyurethane to increase the linear range by limiting the diffusion of lactate while maintaining the advantages of the original textile mesh, such as flexibility, stretchability, and permeability. Permeability of the mesh-type lactate-oxidizing anode allowed a vertically stacked structure of the anode and a previously developed air-breathing cathode. This resulted in a small overall device size (1 cm2). The mesh-type sensor was tested using a small flow rate of lactate solution, and a moderate linearity of amperometric response for a wide concentration range (5 to >=20 mM) was confirmed. The fluid-permeable anode and enzymatic biofuel cell show the potential of the sensor for continuous monitoring of lactate in perspiration on skin. PMID- 30302488 TI - N,S-Atom-coordinated Co9S8 trinary dopants within a porous graphene framework as efficient catalysts for oxygen reduction/evolution reactions. AB - The intrinsic instability and difficulty in controlling the uniform size distributions of cobalt sulfides greatly restrict their application for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) as a bifunctional electrocatalyst in regenerative fuel cells and rechargeable metal air batteries. Herein, we synthesize a stable electrocatalyst of N,S-atom coordinated Co9S8 trinary dopants within a porous graphene framework (Co9S8@NS 3DrGO), in which Co9S8 nanoparticles show uniform sizes and distributions. The stable Co9S8-based composites are fabricated by a facile soft template-assisted strategy, and the attraction of this method is that the intermediate of melamine formaldehyde resin (MFR) plays trifunctional roles, including (i) it acts as the templated bonding material to crosslink GO sheets together, (ii) it facilitates the formation of a core-shell architecture, and (iii) it acts as the N source for doping. Catalyst composition and performance are largely dependent on the pyrolysis temperature. Extensive investigation elucidates that the mechanism of electrocatalytic activity is attributed to: (i) the unique core-shell structure of the composites, as well as uniform particle sizes and distributions of Co9S8, (ii) the active nitrogen (pyridinic N and graphitic N) contents, and (iii) the large surface area and porous architecture. The composite pyrolyzed at 850 degrees C exhibits the best electrocatalytic performance, which shows a positive ORR half-wave potential (0.826 V), a small OER overpotential (317 mV) at 10 mA cm 2, and high stability, comparable to the commercial noble catalysts Pt/C and RuO2 in alkaline media. Furthermore, when applied in zinc-air batteries, it also displays a comparable performance to a Pt/C + RuO2 mixture catalyst. This work provides an approach to stabilize cobalt sulfides and control their particle sizes and distributions by ingeniously employing the soft template of MFR and pyrolyzing them at various temperatures. PMID- 30302487 TI - An integrated adipose-tissue-on-chip nanoplasmonic biosensing platform for investigating obesity-associated inflammation. AB - Although many advanced biosensing techniques have been proposed for cytokine profiling, there are no clinically available methods that integrate high resolution immune cell monitoring and in situ multiplexed cytokine detection together in a biomimetic tissue microenvironment. The primary challenge arises due to the lack of suitable label-free sensing techniques and difficulty for sensor integration. In this work, we demonstrated a novel integration of a localized-surface plasmon resonance (LSPR)-based biosensor with a biomimetic microfluidic 'adipose-tissue-on-chip' platform for an in situ label-free, high throughput and multiplexed cytokine secretion analysis of obese adipose tissue. Using our established adipose-tissue-on-chip platform, we were able to monitor the adipose tissue initiation, differentiation, and maturation and simulate the hallmark formation of crown-like structures (CLSs) during pro-inflammatory stimulation. With integrated antibody-conjugated LSPR barcode sensor arrays, our platform enables simultaneous multiplexed measurements of pro-inflammatory (IL-6 and TNF-alpha) and anti-inflammatory (IL-10 and IL-4) cytokines secreted by the adipocytes and macrophages. As a result, our adipose-tissue-on-chip platform is capable of identifying stage-specific cytokine secretion profiles from a complex milieu during obesity progression, highlighting its potential as a high throughput preclinical readout for personalized obesity treatment strategies.

AB - Here, we report a palladium-catalyzed controllable cyclization of vinyl ethylene carbonates that proceeds through formal migration [2+3] and [5+2] cycloadditions, respectively, under mild conditions. The transformation described here affords a series of synthetically versatile 5,7-membered N-heterocycles which are found in natural products and pharmaceuticals with biological and medicinal properties. PMID- 30302490 TI - Inhibition and decision-processing speed are associated with performance on dynamic posturography in older adults. AB - Changes in cognition due to age have been associated with falls and reduced standing postural control. Sensory integration is one component of postural control that may be influenced by certain aspects of cognitive functioning. This study investigated associations between measures of cognitive function and sensory integration capabilities for healthy young and older adults. Dynamic posturography was performed using the Equitest Sensory Organization Test (SOT) protocol to evaluate sensory integration during standing using sway-referencing of the platform and/or visual scene to alter somatosensory and visual inputs. The Equilibrium Score was used as a measure of sway. Cognitive testing examined aspects of cognitive function that have been associated with falls in older adults. A correlational analysis investigated associations between the cognitive measures and postural sway during the altered sensory conditions of the SOT. For older subjects only, slower decision-processing speed was associated with increased sway during SOT conditions whenever somatosensation was altered. Reduced perceptual inhibition was associated with increased sway whenever somatosensation was intact, and particularly when vision was altered in the presence of somatosensation. Visuospatial construct ability was associated with sway only when the eyes were closed during altered somatosensation. Task switching was associated with sway only when vision and somatosensation were intact. With increased age, deficits in decision speed and inhibition appear associated with the sensory integration crucial for balance maintenance. Associations are modulated by the availability of somatosensation and vision. These associations define situations and individual differences in aspects of cognition that may relate to situational loss of balance in older adults. PMID- 30302491 TI - Is oxidized low-density lipoprotein the connection between atherosclerosis, cardiovascular risk and nephrolithiasis? AB - Nephrolithiasis is considered a systemic disease. A link has been established between nephrolithiasis, cardiovascular disease (CVD), the metabolic syndrome and atherosclerosis. A significant correlation has been found between the high levels of oxidized low-density lipoprotein (oxLDL) and CVD and atherosclerosis, including coronary and femoral artery disease. To the best of our knowledge, oxLDL has not been evaluated in patients with nephrolithiasis. This study aimed to evaluate serum levels of oxLDL, anti-oxLDL antibodies (oxLDL-ab) and other markers of atherosclerosis in patients with nephrolithiasis, according to the severity of the disease. The population sample consisted of 94 patients of 30-70 years of age with no symptoms of CVD who presented with renal calculi documented by ultrasonography, abdominal X-ray or computed tomography. The patients were divided into two groups: Group 1 (>= 3 stones) and Group 2 (1-2 stones). A comparison control group was formed with 21 healthy individuals. Enzyme-linked immunosorbent assays were used to assess oxLDL and oxLDL-ab. Lipid peroxidation indexes were also analyzed. Median serum oxLDL values were higher in Groups 1 and 2 compared to the control group (>= 3 stones, p = 0.02; 1-2 stones, p = 0.03). Median serum anti-oxLDL antibody levels were lower in the patients in Group 1 compared to the controls (p = 0.03). There was no significant difference in the oxLDL/oxLDL-ab ratio between patients and controls. These findings suggest that this may be the link between nephrolithiasis and the greater incidence of atherosclerosis and cardiovascular disease in patients with kidney stones.

Several factors play a role: age, multimorbidity including impaired renal function and neuropathy make access to life-prolonging chemotherapy impossible in many cases. Improvements of response rates and overall survival in the second-line setting are not much different compared to best supportive care. However, the therapeutic landscape has changed dramatically during the last 2 years. Immunotherapies represented by checkpoint inhibitors have showed positive trial outcomes and have been approved by EMA (European Medicines Agency). Both in second-line therapy after platinum-based chemotherapy and in first-line therapy in unfit patients, these drugs can be used. New concepts with combinations of immunotherapeutic compounds are currently being examined in various trials. If we follow the data of other malignancies (melanoma and non-small cell lung cancer), the future looks optimistic. PMID- 30302495 TI - Quality of life after staged bilateral total knee arthroplasty: a minimum five year follow-up study of seventy-eight patients. AB - PURPOSE: Although many studies have been performed to evaluate the quality of life (QOL) and patient satisfaction after total knee arthroplasty (TKA), almost all evaluations were performed in patients after unilateral TKA or in patients after mixed unilateral and bilateral TKA. Accordingly, this study aimed to evaluate QOL after staged bilateral TKA. METHODS: A total of 78 patients who underwent staged bilateral TKA for varus knee osteoarthritis were included in this study. All patients had longitudinal follow-up evaluations for at least five years. QOL was assessed by the Japanese Knee Osteoarthritis Measure (JKOM), a disease-specific and patient-derived QOL measure for Japanese patients. Conventional objective outcome scales, including the Knee Society Score and the Timed Up and Go test, were also assessed. In addition, QOL and objective outcomes were compared between the younger (<= 80 years, average 75.8 years) and older (> 80 years, average 84.7 years) age groups at the final follow-up. RESULTS: Improvements in both JKOM and objective outcomes reached a plateau one year after staged bilateral TKA. Improvements were prolonged for more than five years. There were no statistically significant differences in JKOM or objective outcomes between the younger and older age groups, despite an 8.9-year difference in the average age. CONCLUSIONS: This was the first longitudinal study to evaluate QOL and objective outcomes after staged bilateral TKA for a period of at least five years. Improvements in QOL and objective outcomes reached a plateau one year after staged bilateral TKA and were prolonged for more than five years. No significant differences were observed in outcome scores between the younger and older age groups.

On the one hand, reliable evidence-based recommendations regarding surgical resection as well as lymph node management have been established on the basis of results from randomized multicenter studies. On the other hand, the advent of targeted therapies has led to spectacular improvements in the treatment of metastasized melanomas. Knowledge concerning treatment algorithms and updates thereof is also essential for maxillofacial surgeons. The German S3 guideline on diagnosis and treatment of melanoma was published in 2013 and revised in 2016 and 2018. This article informs readers about these developments and addresses the items relevant for treatment of head and neck melanomas in particular. PMID- 30302497 TI - Extensor hallucis longus-transfer for tibialis anterior tendon rupture repair. AB - OBJECTIVE: Restore the function of the tibialis anterior muscle, which is responsible for dorsiflexion and inversion of the foot. INDICATIONS: Spontaneous or traumatic rupture of the tibialis anterior tendon. CONTRAINDICATIONS: Patients with multimorbidity or lack of functional demands. SURGICAL TECHNIQUE: Direct repair of the tibialis anterior tendon with fiber-wire suture and augmentation with extensor hallucis longus tendon, potentially in combination with reinsertion of the tibialis anterior tendon in the medial cuneiform. POSTOPERATIVE MANAGEMENT: Six weeks of non-weight-bearing: 3 weeks of cast immobilization with ankle in 10 degrees dorsiflexion, followed by 3 weeks of splint immobilization and passive mobilization. Then stepwise increase in weight-bearing over a period of 2-3 weeks. RESULTS: In 8 patients postoperative results with a mean follow-up of 13.5 months were available. One patient showed a rerupture of the augmented tendon. The mean American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score was 81.0 (range 67-88). The median ankle dorsiflexion muscle strength was 67% (range 29.3-85.5%) compared to the nonoperated leg. All patients, except the one that experienced rerupture, were very satisfied or satisfied with the result. PMID- 30302498 TI - Opposing roles of eosinophils in cancer. AB - Eosinophils are a subset of granulocytes mostly known for their ability to combat parasites and induce allergy. Although they were described to be related to cancer more than 100 years ago, their role in tumors is still undefined. Recent observations revealed that they display regulatory functions towards other immune cell subsets in the tumor microenvironment or direct cytotoxic functions against tumor cells, leading to either antitumor or protumor effects. This paradoxical role of eosinophils was suggested to be dependent on the different factors in the TME. In addition, the clinical relevance of these cells has been recently addressed. In most cases, the accumulation of eosinophils both in the tumor tissue, called tumor-associated tissue eosinophilia, and in the peripheral blood were reported to be prognostic markers for a better outcome of cancer patients. In immunotherapy of cancer, particularly in therapy with immune checkpoint inhibitors, eosinophils were even shown to be a potential predictive marker for a beneficial clinical response. A better understanding of their role in cancer progression will help to establish them as prognostic and predictive markers and to design strategies for targeting eosinophils. PMID- 30302500 TI - Congo Red affects the growth, morphology and activity of glucosamine-6-phosphate synthase in the human pathogenic fungus Sporothrix schenckii. AB - Sporothrix schenckii is the etiological agent of sporotrichosis, a mycosis of humans and other mammals. Little is known about the responses of this thermodimorphic pathogen to perturbations in the cell wall (CW) by different stress conditions. Here we describe the effect of Congo Red (CR) on the fungal growth, morphogenesis and activity of glucosamine-6-phosphate (GlcN-6-P) synthase. Under conditions of yeast development, 15 uM CR abolished conidia (CN) germination, but when yeast cells were first obtained in the absence of the dye and then post-incubated in its presence, yeasts rapidly differentiated into mycelial cells. On the other hand, under conditions of mycelium development, 150 uM CR did not affect CN germination, but filamentous cells underwent structural changes characterized by a distorted CW contour, the loss of polarity and the formation of red-pigmented, hyphal globose structures. Under these conditions, CR also induced a significant and transient increase in the activity of GlcN-6-P synthase, an essential enzyme in CW biogenesis. PMID- 30302499 TI - Assessment of myelination progression in subcortical white matter of children aged 6-48 months using T2-weighted imaging. AB - PURPOSE: This study aims to provide a screening scoring method by assessing the age-related change of subcortical white matter (WM) myelination via T2-weighted imaging (T2WI). METHODS: This study retrospectively recruited 109 children aged 6 48 months without abnormalities on MRI. Based on Parazzini's study, we developed a modified T2WI-based method to assess subcortical WM myelination (frontal, temporal, parietal, occipital lobes, and insula) by scoring WM's signal changes. Inter- and intra-observer agreements were evaluated by Bland-Altman plot. Age related changes of myelination score were explored by locally weighted scatterplot smoothing (LOESS), linear regression, and Spearman correlation coefficients (r). Relationships between diffusion tensor imaging (DTI) metrics and total myelination score were investigated to further validate practicability of the scoring method by tract-based spatial statistics (TBSS). RESULTS: This method showed good intra-observer (mean difference = 0.18, SD = 0.95) and inter observer agreements (mean difference = - 0.06, SD = 1.01). The LOESS and linear regression results indicated that myelination proceeded in two phases: a period of rapid growth (6-20 months; slope = 0.561) and one of slower growth (21-48 months; slope = 0.097). Significant correlations between myelination score and age were observed in whole subcortical WM (r = 0.945; P < 0.001) and all regional subcortical WM (r_mean = 0.819, range, 0.664-0.928; P < 0.001). TBSS found significant correlations of WM-DTI metrics with myelination score during the range of 6-20 months, while no significant correlation was observed in 21-48 months. CONCLUSION: The modified T2WI-based screening scoring method is easily feasible to assess myelination progression of subcortical WM, especially suitable for children aged 6-20 months. It may show potential in identifying individual developmental abnormalities by scoring assessment in the future clinical practice.

AB - Implementation of a new phylonumerics approach to construct a mass tree representing over 6000 H1N1 human influenza strains has enabled ancestral and compensatory descendant mutations to be identified in N1 neuraminidase that promote antiviral resistance and restore viral fitness. Adjacent to the H275Y resistance mutation site, mutations S299A and S247N, respectively, lead the evolution of oseltamivir-resistant strains and restore viral fitness to those strains thereafter. Importantly the mass tree phylonumerics approach can identify such mutations globally, without any positional bias, so that functionally linked or compensatory mutations remote in the sequence or structure of the protein can be identified and interrogated. This is achieved using mass map datasets commonly employed for protein identification in proteomics applications, thus avoiding the need for either gene or protein sequences that are central to other phylogenetic methods.

PMID- 30302505 TI - The Case for Cardiac Xenotransplantation in Neonates: Is Now the Time to Reconsider Xenotransplantation for Hypoplastic Left Heart Syndrome? AB - Neonatal cardiac transplantation for hypoplastic left heart syndrome (HLHS) is associated with excellent long-term survival compared to older recipients. However, heart transplantation for neonates is greatly limited by the critical shortage of donor hearts, and by the associated mortality of the long pre transplant waiting period. This led to the development of staged surgical palliation as the first-line surgical therapy for HLHS. Recent advances in genetic engineering and xenotransplantation have provided the potential to replicate the excellent results of neonatal cardiac allotransplantation while eliminating wait-list-associated mortality through genetically modified pig-to human neonatal cardiac xenotransplantation. The elimination of the major pig antigens in addition to the immature B-cell response in neonates allows for the potential to induce B-cell tolerance. Additionally, the relatively mature neonatal T-cell response could be reduced by thymectomy at the time of operation combined with donor-specific pig thymus transplantation to "reprogram" the host's T-cells to recognize the xenograft as host tissue. In light of the recent significantly increased graft survival of genetically-engineered pig-to-baboon cardiac xenotransplantation, we propose that now is the time to consider devoting research to advance the potential clinical application of cardiac xenotransplantation as a treatment option for patients with HLHS.

AB - BACKGROUND AND PURPOSE: During head-and-neck (H&N) radiotherapy, the parotid glands (PGs) may be overdosed; thus, a tool is required to monitor the delivered dose. This study aimed to assess the dose accuracy of a patient-specific density assignment method (DAM) for dose calculation to monitor the dose to PGs during treatment. PATIENTS AND METHODS: Forty patients with H&N cancer received an intensity modulated radiation therapy (IMRT), among whom 15 had weekly CTs. Dose distributions were calculated either on the CTs (CTref), on one-class CTs (1C-CT, water), or on three-class CTs (3C-CT, water-air-bone). The inter- and intra patient DAM uncertainties were evaluated by the difference between doses calculated on CTref and 1C-CTs or 3C-CTs. PG mean dose (Dmean) and spinal cord maximum dose (D2%) were considered. The cumulated dose to the PGs was estimated by the mean Dmean of the weekly CTs. RESULTS: The mean (maximum) inter-patient DAM dose uncertainties for the PGs (in cGy) were 23 (75) using 1C-CTs and 12 (50) using 3C-CTs (p <= 0.001). For the spinal cord, these uncertainties were 118 (245) and 15 (67; p <= 0.001). The mean (maximum) DAM dose uncertainty between cumulated doses calculated on CTs and 3C-CTs was 7 cGy (45 cGy) for the PGs. Considering the difference between the planned and cumulated doses, 53% of the ipsilateral and 80% of the contralateral PGs were overdosed by +3.6 Gy (up to 8.2 Gy) and +1.9 Gy (up to 5.2 Gy), respectively. CONCLUSION: The uncertainty of the three-class DAM appears to be clinically non-significant (<0.5 Gy) compared with the PG overdose (up to 8.2 Gy). This DAM could therefore be used to monitor PG doses and trigger replanning. PMID- 30302508 TI - 35.

AB - Knowledge of dose linearity, plasma clearance, rate and extent of subcutaneous (SC) and intramuscular (IM) absorption of soluble aluminium (Al) citrate is considered a prerequisite for evaluation of toxicokinetic data obtained from SC or IM administration of Al adjuvants in medicinal products. Therefore, total Al plasma kinetics was investigated after SC, IM, and IV administration of single Al doses (36 and 360 ug/kg IM or SC; 30 and 300 ug/kg IV) given as citrate solution in rats. Control groups receiving vehicle (saline) were run in parallel to monitor background plasma Al levels over time resulting from dietary intake. Evaluation of Al plasma profiles was done by both non-compartmental analysis of baseline-corrected data and simultaneous model fitting to the raw data using a population kinetics approach. High and dose-independent total plasma clearance (6.6 mL/min/kg) was observed after IV administration corresponding to 60-82% of normal rat GFR. This supports the previous assumptions that parenterally administered Al citrate is more rapidly cleared from plasma than other Al species (e.g., chloride or lactate). Furthermore, plasma exposure of Al (Cmax and AUC0 inf) increased dose-proportionally at all administration routes. Fast and complete absorption of Al was observed at each dose level after both SC and IM administration (bioavailability estimates: 88 and 110%). Estimates for the first order absorption rate constant ka correspond to absorption half-lives of 36 min (SC) and <= 13 min (IM). There was no increase in tissue Al content (whole bone and brain) after 36 ug/kg IM compared to control rats. PMID- 30302510 TI - English on cigarette packs from six non-Anglophone low- and middle-income countries. AB - OBJECTIVES: Low- and middle-income countries (LMICs) are vital to the global tobacco market. The pack is key to cigarette branding, and review of cigarette packs revealed English as a common feature. The prevalence of English and its potential branding utility is explored. METHODS: Every available unique cigarette pack was purchased from diverse retailers in six LMICs where English is not the official language (Bangladesh, Brazil, China, Egypt, Ukraine, Vietnam). Packs' front panels were coded for English on pack fronts. English penetration was quantified by country and a comparison of English use between multinational and national brands was undertaken. A qualitative analysis of symbolic and utilitarian usage of English was conducted. RESULTS: Of 1303 unique cigarette packs analyzed, 67% (n = 876) included some English. English text conveyed product information and usage instruction. English was more prevalent for multinational brands. Qualitatively, English use frequently connected cigarettes with concepts of quality, style, luxury, and aspirational lifestyle. CONCLUSIONS: Restricting English use should be incorporated into plain packaging policy to protect populations from deceptive branding practices, specifically presenting cigarettes as an aspirational product. PMID- 30302511 TI - Acute and long-lasting effects of oxytocin in cortico-limbic circuits: consequences for fear recall and extinction. AB - The extinction of conditioned fear responses entrains the formation of safe new memories to decrease those behavioral responses. The knowledge in neuronal mechanisms of extinction is fundamental in the treatment of anxiety and fear disorders. Interestingly, the use of pharmacological compounds that reduce anxiety and fear has been shown as a potent co-adjuvant in extinction therapy. However, the efficiency and mechanisms by which pharmacological compounds promote extinction of fear memories remains still largely unknown and would benefit from a validation based on functional neuronal circuits, and the neurotransmitters that modulate them. From this perspective, oxytocin receptor signaling, which has been shown in cortical and limbic areas to modulate numerous functions (Eliava et al. Neuron 89(6):1291-1304, 2016), among them fear and anxiety circuits, and to enhance the salience of social stimuli (Stoop Neuron 76(1):142-59, 2012), may offer an interesting perspective. Experiments in animals and humans suggest that oxytocin could be a promising pharmacological agent at adjusting memory consolidation to boost fear extinction. Additionally, it is possible that long term changes in endogenous oxytocin signaling can also play a role in reducing expression of fear at different brain targets. In this review, we summarize the effects reported for oxytocin in cortico-limbic circuits and on fear behavior that are of relevance for the modulation and potential extinction of fear memories. PMID- 30302506 TI - Target identification for the diagnosis and intervention of vulnerable atherosclerotic plaques beyond 18F-fluorodeoxyglucose positron emission tomography imaging: promising tracers on the horizon. AB - Cardiovascular disease is the major cause of morbidity and mortality in developed countries and atherosclerosis is the major cause of cardiovascular disease. Atherosclerotic lesions obstruct blood flow in the arterial vessel wall and can rupture leading to the formation of occlusive thrombi. Conventional diagnostic tools are still of limited value for identifying the vulnerable arterial plaque and for predicting its risk of rupture and of releasing thromboembolic material. Knowledge of the molecular and biological processes implicated in the process of atherosclerosis will advance the development of imaging probes to differentiate the vulnerable plaque. The development of imaging probes with high sensitivity and specificity in identifying high-risk atherosclerotic vessel wall changes and plaques is crucial for improving knowledge-based decisions and tailored individual interventions. Arterial PET imaging with 18F-FDG has shown promising results in identifying inflammatory vessel wall changes in numerous studies and clinical trials. However, due to its limited specificity in general and its intense physiological uptake in the left ventricular myocardium that impair imaging of the coronary arteries, different PET tracers for the molecular imaging of atherosclerosis have been evaluated. This review describes biological, chemical and medical expertise supporting a translational approach that will enable the development of new or the evaluation of existing PET tracers for the identification of vulnerable atherosclerotic plaques for better risk prediction and benefit to patients. PMID- 30302512 TI - Human Microbiome: Composition and Role in Inflammatory Skin Diseases. AB - This review focuses on recent evidences about human microbiome composition and functions, exploring the potential implication of its impairment in some diffuse and invalidating inflammatory skin diseases, such as atopic dermatitis, psoriasis, hidradenitis suppurativa and acne. We analysed current scientific literature, focusing on the current evidences about gut and skin microbiome composition and the complex dialogue between microbes and the host. Finally, we examined the consequences of this dialogue for health and skin diseases. This review highlights how human microbes interact with different anatomic niches modifying the state of immune activation, skin barrier status, microbe-host and microbe-microbe interactions. It also shows as most of the factors affecting gut and skin microorganisms' activity have demonstrated to be effective also in modulating chronic inflammatory skin diseases. More and more evidences demonstrate that human microbiome plays a key role in human health and diseases. It is to be expected that these new insights will translate into diagnostic, therapeutic and preventive measures in the context of personalized/precision medicine.

PMID- 30302514 TI - Variant termination of first and second jejunal veins into a "pancreatic portal vein". AB - Jejunal veins usually terminate into the superior mesenteric vein. Here, an unusual termination of first and second jejunal veins into a pancreatic portal vein has been presented. The common vein formed by the first and second jejunal veins could be named as pancreatic portal vein because it divided into two branches in front of the third part of the duodenum and these two branches entered the head of the pancreas and further divided into smaller branches before anastomosing with the tributaries of pancreatico-duodenal veins. The knowledge of this rare vein could be useful to radiologists and surgeons.

AB - BACKGROUND: Electroconvulsive therapy (ECT) is a highly effective, yet still controversial therapy for both the general public and psychiatrists. In this study, we investigated the patients' view regarding effectiveness and tolerability of electroconvulsive therapy under consideration of individual clinical response. MATERIAL AND METHODS: In 31 patients with major depression, subjective effectiveness and tolerability were assessed via a differentiated questionnaire prior to, during, and after ECT. Symptoms were rated using the Montgomery-Asberg depression rating scale (MADRS) and the Beck depression inventory II (BDI-II) RESULTS: Patients assessed ECT to be generally effective both before and after the treatment. This view was independent of their individual treatment success. In contrast, patients' rating of individual effectiveness depended on the objective improvement of their symptoms. Side effects were rated to be generally slight to moderate. CONCLUSION: Against the background of persisting criticism towards ECT, the viewpoint of involved patients provides us with important references for an appropriate judgement of this therapy. The results suggest a good benefit-risk ratio for ECT from the patients' perspective. PMID- 30302516 TI - [Patho- and therapyepigenetics of mental disorders]. AB - Epigenetic mechanisms, such as DNA methylation and histone modifications are biochemical alterations of the DNA or its spatial structure. They regulate gene function, can be modified by environmental influences and are temporally dynamic. In this review, the current state of knowledge regarding the role of epigenetics in the pathogenesis of mental disorders is summarized exemplarily for schizophrenia, depression, anxiety disorders and posttraumatic stress disorder. Additionally, findings on epigenetic alterations in the course of pharmacotherapeutic and psychotherapeutic interventions are presented. Epigenetic mechanisms have a central function at the crossroads between genes and environment and consequently in the vulnerability-stress model of mental disorders. Prospectively, in line with a precision medicine approach epigenetic profiles may represent useful markers of disease risk and therapy response or even constitute new druggable targets. PMID- 30302517 TI - [Video-assisted patient education in anesthesia : How do medical users assess the procedure?] AB - BACKGROUND: Video-assisted patient education (VaPE) has in the past been a subject of many studies. Compared to conventional methods, most authors reported a better transfer of information, some found increased patient satisfaction and a time-sparing effect. There was no increase in anxiety caused by VaPE. Some authors even found a reduction of anxiety levels before anesthesia. All publications to date have focused on the patient's point of view. There have been no reports on how anesthetists as users assess VaPE. METHODS: In this study 22 anesthesia departments using VaPE were contacted. A total of 122 anesthetists were sent questionnaires of which 81 (66%) were completed and returned. The anesthetists were first questioned about the characteristics of the workplace, the frequency of preanesthesia patient contacts, the content of the videos, the technique of video presentation and their own professional experience. After this the anesthetists were asked to assess five statements concerning: usefulness of VaPE, economy of time, transfer of knowledge, induction of anxiety and influence on the quality of the consent interview. In each category there were 4 choices: fully agree, partly agree, partly disagree and fully disagree. The first two choices were evaluated as positive and the second two as negative answers. The anesthetists were also asked to state the most valued characteristics of VaPE. Out of eight given options they were to select the most favored three. A final question was whether in their opinion VaPE could be recommended to non-users. RESULTS: Of the anesthetists 97.5% stated that disclosure interviews predominantly took place in the preoperative anesthetic clinic and 73% performed 15 or more patient interviews per day. Videos about general anesthesia were applied by 70%, about non-obstetric regional anesthesia by 56% and about obstetric epidural anesthesia by 59%. The videos were presented to groups of patients via large screens by 27%, individually with CD players or tablet computers by 51% or with both methods (22%). Of the anesthetists 69% had 5 years or more professional experience, 97.5% found VaPE useful for patients education, 92.5% observed a time-saving effect for the following interview and 96% stated that after watching the video patients were better informed. An increase of anxiety caused by VaPE was noted by 46% whereas 54% found no such effect. As to the quality of interview 50% reported an advantage in focusing on the patient's individual risk profile and the other 50% reported no advantage. The ranking of the main advantages was 1) better patient information, 2) time-saving effect, 3) helpful for patient education, followed by 4) increased patient satisfaction, 5) better understanding of anesthesiology, 6) individualization of the interview and 7) helpful in questions of legal liability. The answer option "no advantage" was not chosen at all. Of the participants 82.5% would recommend VaPE unconditionally (fully agree), 17.5% would give a conditional recommendation to colleagues and no one would not recommend VaPE. CONCLUSION: This survey among anesthetists confirmed most results obtained from patient-based studies: medical users attributed to VaPE a better information transfer and a time-sparing effect. Furthermore, users regarded VaPE as helpful for the preanesthesia interview. As compared to the patient-based results, however, many anesthetists seem to overrate the anxiety, caused by disclosure videos. From the users' point of view, VaPE is a highly appreciated method for patient education which can be recommended to colleagues. PMID- 30302518 TI - Microbial forensics: new breakthroughs and future prospects. AB - Recent advances in genetic data generation, through massive parallel sequencing (MPS), storage and analysis have fostered significant progresses in microbial forensics (or forensic microbiology). Initial applications in circumstances of biocrime, bioterrorism and epidemiology are now accompanied by the prospect of using microorganisms (i) as ancillary evidence in criminal cases; (ii) to clarify causes of death (e.g., drownings, toxicology, hospital-acquired infections, sudden infant death and shaken baby syndromes); (iii) to assist human identification (skin, hair and body fluid microbiomes); (iv) for geolocation (soil microbiome); and (v) to estimate postmortem interval (thanatomicrobiome and epinecrotic microbial community). When compared with classical microbiological methods, MPS offers a diverse range of advantages and alternative possibilities. However, prior to its implementation in the forensic context, critical efforts concerning the elaboration of standards and guidelines consolidated by the creation of robust and comprehensive reference databases must be undertaken. PMID- 30302519 TI - Characterization and use of a bacterial lignin peroxidase with an improved manganese-oxidative activity. AB - Peroxidases are well-known biocatalysts produced by all organisms, especially microorganisms, and used in a number of biotechnological applications. The enzyme DypB from the lignin-degrading bacterium Rhodococcus jostii was recently shown to degrade solvent-obtained fractions of a Kraft lignin. In order to promote the practical use, the N246A variant of DypB, named Rh_DypB, was overexpressed in E. coli using a designed synthetic gene: by employing optimized conditions, the enzyme was fully produced as folded holoenzyme, thus avoiding the need for a further time-consuming and expensive reconstitution step. By a single chromatographic purification step, > 100 mg enzyme/L fermentation broth with a > 90% purity was produced. Rh_DypB shows a classical peroxidase activity which is significantly increased by adding Mn2+ ions: kinetic parameters for H2O2, Mn2+, ABTS, and 2,6-DMP were determined. The recombinant enzyme shows a good thermostability (melting temperature of 63-65 degrees C), is stable at pH 6-7, and maintains a large part of the starting activity following incubation for 24 h at 25-37 degrees C. Rh_DypB activity is not affected by 1 M NaCl, 10% DMSO, and 5% Tween-80, i.e., compounds used for dye decolorization or lignin-solubilization processes. The enzyme shows broad dye-decolorization activity, especially in the presence of Mn2+, oxidizes various aromatic monomers from lignin, and cleaves the guaiacylglycerol-beta-guaiacyl ether (GGE), i.e., the Calpha-Cbeta bond of the dimeric lignin model molecule of beta-O-4 linkages. Under optimized conditions, 2 mM GGE was fully cleaved by recombinant Rh_DypB, generating guaiacol in only 10 min, at a rate of 12.5 MUmol/min mg enzyme. PMID- 30302520 TI - Soil acidification amendments change the rhizosphere bacterial community of tobacco in a bacterial wilt affected field. AB - Application of soil amendments has been wildly used to increase soil pH and control bacterial wilt. However, little is known about causal shifts in the rhizosphere microbial community of crops, especially when the field naturally harbors the disease of bacterial wilt to tobacco for many years due to long-term continuous cropping and soil acidification. In this study, biochar (CP), lime (LM), oyster shell powder (OS) and no soil amendment additions (Control; CK) were assessed for their abilities to improve the soil acidification, change the composition of rhizosphere soil bacterial communities and thus control tobacco bacterial wilt. The results showed that oyster shell powder significantly increased soil pH by 0.77 and reduced the incidence of tobacco bacterial wilt by 36.67% compared to the control. The Illumina sequencing -based community analysis showed that soil amendment applications affected the composition of rhizosphere bacterial community and increased the richness and diversity. In contrast, the richness and diversity correlated negatively to disease incidence. Using LEfSe analyses, 11 taxa were found to be closely related with disease suppression, in which Saccharibacteria, Aeromicrobium, and Pseudoxanthomonas could be potential indicators of disease suppression. Our results suggested that the suppression of bacterial wilt after the application of soil amendments (especially oyster shell powder) was attributed to the improved soil pH and increased bacterial richness and diversity. PMID- 30302521 TI - Alterations in the diversity and composition of mice gut microbiota by lytic or temperate gut phage treatment. AB - Phages, the most abundant species in the mammalian gut, have numerous advantages as biocontrol agent over antibiotics. In this study, mice were orally treated with the lytic gut phage PA13076 (group B), the temperate phage BP96115 (group C), no phage (group A), or streptomycin (group D) over 31 days. At the end of the experiment, fecal microbiota diversity and composition was determined and compared using high-throughput sequencing of the V3-V4 hyper-variable region of the 16S rRNA gene and virus-like particles (VLPs) were quantified in feces. There was high diversity and richness of microbiota in the lytic and temperate gut phage-treated mice, with the lytic gut phage causing an increased alpha diversity based on the Chao1 index (p < 0.01). However, the streptomycin treatment reduced the microbiota diversity and richness (p = 0.0299). Both phage and streptomycin treatments reduced the abundance of Bacteroidetes at the phylum level (p < 0.01) and increased the abundance of the phylum Firmicutes. Interestingly, two beneficial genera, Lactobacillus and Bifidobacterium, were enhanced by treatment with the lytic and temperate gut phage. The abundance of the genus Escherichia/Shigella was higher in mice after temperate phage administration than in the control group (p < 0.01), but lower than in the streptomycin group. Moreover, streptomycin treatment increased the abundance of the genera Klebsiella and Escherichia/Shigella (p < 0.01). In terms of the gut virome, fecal VLPs did not change significantly after phage treatment. This study showed that lytic and temperate gut phage treatment modulated the composition and diversity of gut microbiota and the lytic gut phage promoted a beneficial gut ecosystem, while the temperate phage may promote conditions enabling diseases to occur. PMID- 30302522 TI - E. coli Nissle microencapsulation in alginate-chitosan nanoparticles and its effect on Campylobacter jejuni in vitro. AB - Microencapsulation enhances the oral delivery of probiotic bacteria. In this study, the probiotic Escherichia coli Nissle 1917 (EcN) was microencapsulated using alginate and chitosan nanoparticles. The result showed 90% encapsulation yield of EcN, and the encapsulated EcN displayed significantly (P < 0.05) increased survival in low pH (1.5), high bile salt concentration (4%), and high temperature (70 degrees C). The most effective cryopreservatives of EcN during freezing and thawing was skim milk and sucrose. Exposure to microencapsulated EcN significantly (P < 0.05) reduced the Campylobacter jejuni growth by 2 log CFU. The rate of EcN release from microcapsule was 9.2 * 105 cell min-1, and the appropriate model to describe its release kinetics was zero order. Importantly, the entrapment of EcN inside the microcapsule did not eliminate the exterior diffusion of EcN produced antioxidant compounds. In addition, the EcN microcapsule efficiently adhered to intestinal HT-29 cells and the pre-treatment of HT-29 cells with EcN-microcapsule for 4 h significantly (P < 0.05) reduced the invasion (1.9 log) of C. jejuni; whereas, completely abolished the intracellular survival. Furthermore, HT-29 cells pre-treated with encapsulated EcN in PCR array showed decreased expression (> 1.5-fold) of genes encoding chemokines, toll-like receptors, interleukins, and tumor necrosis factors. In conclusion, the alginate chitosan microcapsule can provide effectual platform to deliver probiotic EcN and thereby can reduce the Campylobacter infection in chickens and humans. PMID- 30302523 TI - FOXC2 promotes epithelial-mesenchymal transition and cisplatin resistance of non small cell lung cancer cells. AB - PURPOSE: Platinum-based drugs, particularly cisplatin (DDP), are used in the treatment of non-small cell lung cancer (NSCLC). However, development of drug resistance remains the major therapeutic barrier in NSCLC. METHODS: The potential cisplatin resistance-related genes were identified from the global transcriptomes of cisplatin-resistant A549/DDP cells using microarray analysis. Gain- and loss of-function assays were performed to analyze the effects of Forkhead Box Protein C2 (FOXC2) on the in vitro and in vivo sensitivity of NSCLC cells to cisplatin and its possible molecular mechanisms. RESULTS: Using global transcriptome analysis, we found that FOXC2 was one of the most upregulated molecules in A549/DDP cells compared with A549 cells. We further confirmed that the expression of FOXC2 was significantly increased in cisplatin-resistant NSCLC tissues. FOXC2 knockdown significantly increased the in vitro and in vivo sensitivity of A549/DDP cells to cisplatin, whereas overexpression of FOXC2 increased cisplatin resistance in cisplatin-sensitive NSCLC cells. Moreover, we found that FOXC2 promoted cisplatin resistance by induction of epithelial-mesenchymal transition (EMT) in NSCLC cells. Furthermore, FOXC2 activated the AKT/GSK3beta signaling pathway, and then increased the protein expression of EMT-related transcription factor Snail. Inhibition of AKT or knockdown of Snail reversed FOXC2-induced EMT and cisplatin resistance of NSCLC cells. CONCLUSION: FOXC2 enhanced cisplatin resistance of NSCLC cells through activating AKT/GSK3beta/Snail/EMT signaling pathway, which may be a potential novel therapeutic target for overcoming drug resistance in human NSCLCs. PMID- 30302524 TI - Transcoronary pacing : Reliability during myocardial ischemia and after implantation of a coronary stent. AB - BACKGROUND: Transcoronary pacing is a useful therapeutic option for the treatment of unheralded bradycardias in the setting of percutaneous coronary interventions (PCI). OBJECTIVES: In the present study, we investigated the influence of stent implantation and transient myocardial ischemia on the feasibility of transcoronary pacing in a porcine model. METHODS: 7 adult pigs underwent a percutaneous coronary intervention with implantation of a coronary stent under general anaesthesia in an animal catheterization laboratory. Transcoronary pacing was established by using a standard guidewire isolated with an angioplasty balloon positioned in the periphery of the right coronary artery serving as the cathode. As the indifferent anode, a skin patch electrode at the back of the animal was used. The reliability of transcoronary pacing was assessed by measurement of threshold and impedance data and the magnitude of the epicardial electrogram at baseline, after implantation of a coronary stent and finally during myocardial ischemia. RESULTS: Effective transcoronary pacing could be demonstrated in all cases with the standard unipolar transcoronary pacing setup yielding a low pacing threshold at baseline of 1.3 +/- 0.8 V with an impedance of 283 +/- 67 Omega. Implantation of a coronary stent did not influence the pacing threshold (1.0 +/- 0.4 V) and impedance (262 +/- 63 Omega). Acute myocardial ischemia lead to a significant but clinically nonrelevant increase of the pacing threshold to 2.0 +/- 0.6 V and a drop in pacing impedance (137 +/- 39 Omega). CONCLUSIONS: Transcoronary pacing in the animal model is not affected by implantation of a coronary stent in the same vessel used for pacing. Despite a significant increase in pacing threshold, the transcoronary pacing approach is reliable in acute myocardial ischemia during a percutaneous coronary intervention.

Focused echocardiography can detect various cardiac pathologies, such as pericardial effusion, left ventricular dysfunction, right heart strain, relevant heart valve defects and dissection of the ascending aorta. Echocardiographic findings should be interpreted in the clinical context. PMID- 30302526 TI - [Weaning from dialysis after acute kidney injury in chronically critically ill]. AB - This study describes the course of renal recovery after dialysis in a specific population of chronically critically ill patients with a history of prolonged and complicated treatment in an intensive care unit. This study shows that, in a specialized center, patients can be successfully weaned from dialysis even months after acute kidney injury (AKI). Of the patients who could be recompensated (33%), approximately 20% achieved renal recovery more than 3 months after the start of dialysis. The duration of renal recovery after AKI did not differ between those patients with pre-existing chronic kidney disease (CKD) and those without. The reason for dialysis treatment such as sepsis, surgery, resuscitation, as well as the risk factors (e. g., diabetes mellitus, arterial hypertension, arteriosclerosis) did not reveal a difference in weaning in a hazard analysis. As a potential risk factor, only age significantly influenced weaning from dialysis in the multivariate hazard model. PMID- 30302527 TI - [Hospital-acquired pneumonia]. AB - Hospital-acquired pneumonia (HAP) is a frequent complication of hospitalisation. Due to rising multidrug resistant bacteria an appropriate, empiric and targeted therapy is essential and requires an accurate assessment of risk for multidrug resistant bacteria. A targeted, temporal therapy is indispensable and should begin after a focussed diagnosis. Re-evaluation of therapy is important, as clinical course, microbiological and laboratory results might lead to de escalation of therapy. In this review article the current German guidelines on the diagnosis and therapy of hospital-acquired pneumonia are summarized. Special focus is put on targeted, risk-adapted therapy.

AB - Point-of-care ultrasound is a fundamental part of diagnostic and therapeutic management in emergency and intensive care medicine. The availability of high resolution mobile ultrasound systems allows high-quality imaging at the bedside of the patient. Point-of-care ultrasound is not a comprehensive differential diagnostic abdominal ultrasound examination. Rather, the aim of the method is to integrate easily detectable sonographic findings into the clinical context. From this, the necessary diagnostic or therapeutic procedures are derived. This article shows opportunities and limitations of this method. The structure of the article is given by the leading clinical symptoms. The focus is on the ultrasound examination and the characteristic sonographic findings with illustrative ultrasound images. This is followed by a short differential diagnostic interpretation. Further diagnostic or therapeutic management is also briefly addressed. PMID- 30302530 TI - The role of P2Y12 receptor in ischemic stroke of atherosclerotic origin. AB - Atherosclerosis is a chronic and progressive disease of the arterial walls and a leading cause of non-cardioembolic ischemic stroke. P2Y12 is a well-recognized receptor that is expressed on platelets and is a target of thienopyridine-type antiplatelet drugs. In the last few decades, P2Y12 receptor inhibitors, such as clopidogrel, have been applied for the secondary prevention of non-cardioembolic ischemic stroke. Recent clinical studies have suggested that these P2Y12 receptor inhibitors may be more effective than other antiplatelet drugs in patients with ischemic stroke/transient ischemic attack of atherosclerotic origin. Moreover, animal studies have also shown that the P2Y12 receptor may participate in atherogenesis by promoting the proliferation and migration of vascular smooth muscle cells (VSMCs) and endothelial dysfunction, and affecting inflammatory cell activities in addition to amplifying and maintaining ADP-induced platelet activation and platelet aggregation. P2Y12 receptor inhibitors may also exert neuroprotective effects after ischemic stroke. Thus, P2Y12 receptor inhibitors may be a better choice for secondary prevention in patients with atherosclerotic ischemic stroke subtypes because of their triple functions (i.e., their anti atherosclerotic, anti-platelet aggregation, and neuroprotective activities), and the P2Y12 receptor may also serve as a noval therapeutic target for atherosclerosis. In this review, we summarize the current knowledge on the P2Y12 receptor and its key roles in atherosclerosis and ischemic stroke of atherosclerotic origin. PMID- 30302529 TI - Evolvability of the actin cytoskeleton in oligodendrocytes during central nervous system development and aging. AB - The organization of actin filaments into a wide range of subcellular structures is a defining feature of cell shape and dynamics, important for tissue development and homeostasis. Nervous system function requires morphological and functional plasticity of neurons and glial cells, which is largely determined by the dynamic reorganization of the actin cytoskeleton in response to intrinsic and extracellular signals. Oligodendrocytes are specialized glia that extend multiple actin-based protrusions to form the multilayered myelin membrane that spirally wraps around axons, increasing conduction speed and promoting long-term axonal integrity. Myelination is a remarkable biological paradigm in development, and maintenance of myelin is essential for a healthy adult nervous system. In this review, we discuss how structure and dynamics of the actin cytoskeleton is a defining feature of myelinating oligodendrocytes' biology and function. We also review "old and new" concepts to reflect on the potential role of the cytoskeleton in balancing life and death of myelin membranes and oligodendrocytes in the aging central nervous system. PMID- 30302531 TI - A-to-I mRNA editing in fungi: occurrence, function, and evolution. AB - A-to-I RNA editing is an important post-transcriptional modification that converts adenosine (A) to inosine (I) in RNA molecules via hydrolytic deamination. Although editing of mRNAs catalyzed by adenosine deaminases acting on RNA (ADARs) is an evolutionarily conserved mechanism in metazoans, organisms outside the animal kingdom lacking ADAR orthologs were thought to lack A-to-I mRNA editing. However, recent discoveries of genome-wide A-to-I mRNA editing during the sexual stage of the wheat scab fungus Fusarium graminearum, model filamentous fungus Neurospora crassa, Sordaria macrospora, and an early diverging filamentous ascomycete Pyronema confluens indicated that A-to-I mRNA editing is likely an evolutionarily conserved feature in filamentous ascomycetes. More importantly, A-to-I mRNA editing has been demonstrated to play crucial roles in different sexual developmental processes and display distinct tissue- or development-specific regulation. Contrary to that in animals, the majority of fungal RNA editing events are non-synonymous editing, which were shown to be generally advantageous and favored by positive selection. Many non-synonymous editing sites are conserved among different fungi and have potential functional and evolutionary importance.

AB - Duchenne muscular dystrophy (DMD) is an X-linked disease of progressive muscle deterioration and weakness. Patients with DMD have poor bone health which is partly due to treatment with glucocorticoids, a standard therapy to prolong muscle function that also induces bone loss. Bisphosphonates are used to treat adults at risk of glucocorticoid-induced osteoporosis but are not currently used in DMD patients until after they sustain fractures. In this study, C57BL/10ScSn mdx mice, a commonly used DMD animal model, received continuous glucocorticoid, prednisone treatment (0.083 mg/day) from 5 to 10 weeks of age. Pre-treatment with the bisphosphonate pamidronate started at 4 weeks of age over a period of 2 weeks or 6 weeks (cumulative dose 8 mg/kg for both) to assess the effectiveness of the two dosing regimens in ameliorating glucocorticoid-induced bone loss. Mdx mice treated with prednisone had improved muscle function that was not changed by pamidronate treatment. Glucocorticoid treatment caused cortical bone loss and decreased cortical bone strength. Both 2 and 6 week pamidronate treatment increased cortical thickness and bone area compared to prednisone-treated Mdx mice, however, only 2 week pamidronate treatment improved the strength of cortical bone compared to that of glucocorticoid-treated Mdx mice. In the trabecular bone, both pamidronate treatments significantly increased the amount of bone, and increased the ultimate load but not the energy to fail. These results highlight the importance of when and how much bisphosphonate is administered prior to glucocorticoid exposure.

AB - PURPOSE: The purpose of this study was to compare femoral graft bending angle between patients with femoral tunnel reamed at less than 80 degrees of knee flexion and those with 80 degrees and above in anatomical anterior cruciate ligament (ACL) reconstruction using modified transtibial technique. METHODS: Forty-eight patients who underwent ACL reconstruction using bone-patellar-tendon bone autograft in modified transtibial technique and CT scan at 1 week postoperatively were included in this study. A femoral guidewire insertion into aimed femoral position at the medial wall of the femoral lateral condyle was started at about 75 degrees of knee flexion. When the tip of the guidewire was blown out into femoral posterior wall, the guidewire was inserted again after increasing knee flexion angle. Distance from femoral tunnel exit on the femoral lateral cortex-femoral posterior cortex (Distance-E) was measured on postoperative lateral radiograph. Femoral and tibial tunnel position was measured on 3-D CT images. In addition, femoral graft bending angle was measured on reconstructed 2-D CT images. Patients were divided into two groups depending on whether femoral tunnel was created at less than 80 degrees of knee flexion (group A) or 80 degrees or more (group B). RESULTS: There were 32 patients in group A and 16 patients in group B, respectively. Average knee flexion angle was 77.2 degrees [standard deviation (SD) 1.6] in group A and 83.6 degrees (SD 2.4) in group B, respectively (p < 0.05). Average Distance-E was 5.1 mm (SD 2.6) in group A and 6.6 mm (SD 3.8) in group B, respectively. There was no significant difference in the femoral and tibial tunnel position between group A and B. Femoral graft bending angle was significantly smaller in group A [average angle: 50.9 degrees (SD 6.6)] than in group B [average angle: 55.0 degrees (SD 6.6)] (p < 0.05). CONCLUSIONS: Anatomical femoral tunnel was able to be created at less than 80 degrees of knee flexion in two-thirds of patients. Shallower flexion angle (less than 80 degrees ) provided gentler femoral graft bending angle compared to 80 degrees or more of knee flexion. Therefore, femoral tunnel creation in modified transtibial technique should be started at between 75 degrees and 80 degrees of knee flexion to reduce femoral graft bending angle. Shallow knee flexion angle during femoral tunnel creation using modified transtibial technique can reduce femoral graft bending angle and may lead to better clinical outcomes in ACL reconstruction. LEVELS OF EVIDENCE: Retrospective comparative study, Level III. PMID- 30302535 TI - [Gaps in the regulatory T cell shield generate immunopathologies]. PMID- 30302537 TI - [Psychiatric pharmacotherapy of older individuals with severe mental illness]. AB - BACKGROUND: Chronic schizophrenia, depression, and bipolar disorders, among other chronic psychiatric disorders with onset at youth or early adulthood are often referred to as severe mental illness (SMI). Aging with SMI is associated with various psychosocial, physiological, and medical problems with potential impact on psychiatric pharmacotherapy. OBJECTIVES: Determination and discussion of problems and special features of the psychopharmacological treatment of older persons with SMI and presentation of treatment recommendations for the distinct diagnoses. MATERIALS AND METHODS: International literature and guidelines were searched. In addition, the basic literature and expert opinions are discussed. RESULTS: General problems that influence the psychiatric pharmacotherapy of older persons with SMI include nonadherence, nonresponse, polypharmacy, and distinct pharmacokinetic changes with aging and somatic comorbidity. Psychotropic drugs may exhibit cardiovascular, metabolic, and neuropsychiatric risks, among others. The literature regarding effectiveness of psychotropic drugs, drug groups, or combination of drugs in older patients with SMI is scarce to nonexistent. CONCLUSIONS: Drug treatment of older persons with SMI should be part of an overall treatment plan that also has to include social and psychotherapeutic components that address the specific problems of this population. Most importantly, psychiatric pharmacotherapy should consider these risks and the treatment should be tailored to a patient's individual risk profile. Due to a general lack of evidence in this special population, treatment strategies of standard guidelines should be adjusted with special consideration to physiological changes of age. PMID- 30302536 TI - Advances in Imaging and Automated Quantification of Malignant Pulmonary Diseases: A State-of-the-Art Review. AB - Quantitative imaging in lung cancer is a rapidly evolving modality in radiology that is changing clinical practice from a qualitative analysis of imaging features to a more dynamic, spatial, and phenotypical characterization of suspected lesions. Some quantitative parameters, such as the use of 18F-FDG PET/CT-derived standard uptake values (SUV), have already been incorporated into current practice as it provides important information for diagnosis, staging, and treatment response of patients with lung cancer. A growing body of evidence is emerging to support the use of quantitative parameters from other modalities. CT derived volumetric assessment, CT and MRI lung perfusion scans, and diffusion weighted MRI are some of the examples. Software-assisted technologies are the future of quantitative analyses in order to decrease intra- and inter-observer variability. In the era of "big data", widespread incorporation of radiomics (extracting quantitative information from medical images by converting them into minable high-dimensional data) will allow medical imaging to surpass its current status quo and provide more accurate histological correlations and prognostic value in lung cancer. This is a comprehensive review of some of the quantitative image methods and computer-aided systems to the diagnosis and follow-up of patients with lung cancer. PMID- 30302538 TI - Linking structural and effective brain connectivity: structurally informed Parametric Empirical Bayes (si-PEB). AB - Despite the potential for better understanding functional neuroanatomy, the complex relationship between neuroimaging measures of brain structure and function has confounded integrative, multimodal analyses of brain connectivity. This is particularly true for task-related effective connectivity, which describes the causal influences between neuronal populations. Here, we assess whether measures of structural connectivity may usefully inform estimates of effective connectivity in larger scale brain networks. To this end, we introduce an integrative approach, capitalising on two recent statistical advances: Parametric Empirical Bayes, which provides group-level estimates of effective connectivity, and Bayesian model reduction, which enables rapid comparison of competing models. Crucially, we show that structural priors derived from high angular resolution diffusion imaging on a dynamic causal model of a 12-region network-based on functional MRI data from the same subjects-substantially improve model evidence (posterior probability 1.00). This provides definitive evidence that structural and effective connectivity depend upon each other in mediating distributed, large-scale interactions in the brain. Furthermore, this work offers novel perspectives for understanding normal brain architecture and its disintegration in clinical conditions. PMID- 30302539 TI - Gene expression and neurochemical characterization of the rostromedial tegmental nucleus (RMTg) in rats and mice. AB - The rostromedial tegmental nucleus (RMTg), also known as the tail of the ventral tegmental area (tVTA), is a GABAergic structure identified in 2009 that receives strong inputs from the lateral habenula and other sources, sends dense inhibitory projections to midbrain dopamine (DA) neurons, and plays increasingly recognized roles in aversive learning, addiction, and other motivated behaviors. In general, little is known about the genetic identity of these neurons. However, recent work has identified the transcription factor FoxP1 as enhanced in the mouse RMTg (Lahti et al. in Development 143(3):516-529, 2016). Hence, in the current study, we used RNA sequencing to identify genes significantly enhanced in the rat RMTg as compared to adjacent VTA, and then examined the detailed distribution of two genes in particular, prepronociceptin (Pnoc) and FoxP1. In rats and mice, both Pnoc and FoxP1 were expressed at high levels in the RMTg and colocalized strongly with previously established RMTg markers. FoxP1 was particularly selective for RMTg neurons, as it was absent in most adjacent brain regions. We used these gene expression patterns to refine the anatomic characterization of RMTg in rats, extend this characterization to mice, and show that optogenetic manipulation of RMTg in mice bidirectionally modulates real-time place preference. Hence, RMTg neurons in both rats and mice exhibit distinct genetic profiles that correlate with their distinct connectivity and function. PMID- 30302540 TI - Impact of lumbar hypolordosis on the incidence of symptomatic postoperative spinal epidural hematoma after decompression surgery for lumbar spinal canal stenosis. AB - PURPOSE: Potential associations between radiographic parameters and the incidence of symptomatic postoperative spinal epidural hematoma (PSEH) have not been identified. This study aimed to identify risk factors including radiographic parameters for symptomatic PSEH after posterior decompression surgery for lumbar spinal canal stenosis (LSS). METHODS: We retrospectively reviewed 1007 consecutive patients who underwent lumbar decompression surgery for lumbar spinal canal stenosis (LSS) at our institution. We identified 35 cases of symptomatic PSEH, defined by clinical symptoms and MRI findings, and selected 3 or 4 age- and sex-matched control subjects for each PSEH subject (124 controls). We compared radiographic parameters and previously reported risk factors between PSEH and control subjects. RESULTS: Compared to the control group, PSEH patients had significantly higher preoperative systolic (p = .020) and diastolic (p = .048) blood pressure, and more levels of decompression (p = .001). PSEH and control subjects had significant differences in lumbar lordosis (PSEH 24.8 degrees +/- 14.6 degrees , control 34.8 degrees +/- 14.5 degrees ), pelvic tilt (25.1 degrees +/- 11.7 degrees vs. 20.8 degrees +/- 8.4 degrees ), sacral slope (23.4 degrees +/- 9.4 degrees vs. 27.6 degrees +/- 8.3 degrees ), and pelvic incidence minus lumbar lordosis (23.7 degrees +/- 15.0 degrees vs. 13.7 degrees +/- 14.6 degrees ). Multivariate analysis revealed two significant risk factors for PSEH: decompression of two or more levels and lumbar lordosis < 25 degrees . CONCLUSIONS: Multilevel decompression and hypolordosis are significant risk factors for symptomatic PSEH after decompression surgery for LSS. LSS patients with lumbar hypolordosis or multilevel stenosis should be carefully observed for PSEH after decompression surgery. These slides can be retrieved under Electronic Supplementary Material. PMID- 30302541 TI - Axial loading during MRI reveals deviant characteristics within posterior IVD regions between low back pain patients and controls. AB - PURPOSE: To investigate differences in functional intervertebral disk (IVD) characteristics between low back pain (LBP) patients and controls using T2 mapping with axial loading during MRI (alMRI). METHODS: In total, 120 IVDs in 24 LBP patients (mean age 39 years, range 25-69) were examined with T2-mapping without loading of the spine (uMRI) and with alMRI (DynaWell(r) loading device) and compared with 60 IVDs in 12 controls (mean age 38 years, range 25-63). The IVD T2-value was acquired after 20-min loading in five regions of interests (ROI), ROI1-5 from anterior to posterior. T2-values were compared between loading states and cohorts with adjustment for Pfirrmann grade. RESULTS: In LBP patients, mean T2-value of the entire IVD was 64 ms for uMRI and 66 ms for alMRI (p = 0.03) and, in controls, 65 ms and 65 ms (p = 0.5). Load-induced T2-differences (alMRI uMRI) were seen in all ROIs in both patients (0.001 > p < 0.005) and controls (0.0001 > p < 0.03). In patients, alMRI induced an increase in T2-value for ROI1 3 (23%, 18% and 5%) and a decrease for ROI4 (3%) and ROI5 (24%). More pronounced load-induced decrease was detected in ROI4 in controls (9%/p = 0.03), while a higher absolute T2-value was found for ROI5 during alMRI in patients (38 ms) compared to controls (33 ms) (p = 0.04). CONCLUSION: The alMRI-induced differences in T2-value in ROI4 and ROI5 between patients and controls most probably indicate biomechanical impairment in the posterior IVD regions. Hence, alMRI combined with T2-mapping offers an objective and clinical feasible tool for biomechanical IVD characterization that may deepen the knowledge regarding how LBP is related to altered IVD matrix composition.

PMID- 30302542 TI - The effect of training interventions on physical performance, quality of life, and fatigue in patients receiving breast cancer treatment: a systematic review. AB - OBJECTIVES: The primary purpose of this systematic review is to structure the available evidence concerning physical exercise programs and their effects on (1) physical performance outcomes, (2) experienced fatigue, and (3) quality of life (QoL) in patients during the initial treatment for breast cancer. DATA SOURCES: A systematic literature search, based upon the PRISMA guideline, up to January 1, 2018, was performed using four databases (Web of Science, Cochrane Library for Clinical Trials, PubMed, and Medline). STUDY SELECTION: Inclusion criteria were as follows: (1) adults > 18 years; (2) patients with breast cancer undergoing initial treatment; (3) interventions with the aim to influence the patient's physical activity, QoL, or fatigue; (4) randomized controlled trials (RCTs) of all ages. The selected studies were scored for methodological quality, and data concerning physical performance, QoL, and fatigue were extracted. Twenty-eight RCTs were included. DATA EXTRACTION: Different treatment modalities during initial treatment were identified (radiation therapy, chemotherapy, and combination therapy), as well as different types of physical training interventions (cardiovascular endurance exercise, strengthening programs, or a combination of both). Therefore, the results were clustered with regard to the above-mentioned grouping; extracting every relevant outcome related to physical performance (6 MWT or VO2peak; grip/muscle strength), QoL (questionnaires), and fatigue (questionnaires). DATA SYNTHESIS: Different training programs (endurance, resistance, or a combination of both) were found. These programs were applied during different phases of initial treatment. Some programs were supervised while others were home based. Overall, most training interventions provided an improvement in physical performance and a decrease in perceived fatigue. QoL was the outcome variable least susceptible to improvement. CONCLUSION: Different types of exercise programs are available for rehabilitation purposes of breast cancer patients during adjuvant therapy. Overall resistance training or resistance training in combination with CV endurance training provides the best results, especially on physical performance and perceived fatigue.

AB - PURPOSE: To evaluate the clinical characteristics, obstetric/neonatal outcomes, and pregnancy complications of pregnant women with Takayasu arteritis (TA). METHODS: We retrospectively evaluated the data of 22 pregnancies of 11 patients with TA between January 1 2000, and December 31 2017. Patient characteristics, severity of disease, obstetric outcomes, pregnancy complications, mode of delivery, and neonatal outcomes were evaluated. RESULTS: Based on the angiographic classification, four, two, one, three, and one patient were classified into groups I, IIa, III, IV, and V, respectively. Based on Ishikawa criteria, five, two, two, and two patients were classified into groups 2a, 1, 2b, and 3, respectively. Sixteen and five pregnancies resulted in live births and spontaneous abortion, respectively. One pregnancy was terminated due to prenatally diagnosed trisomy 21. Relapse of TA was observed in five pregnancies. Mean age at diagnosis was 24.54 +/- 6.23 years, and mean age at conception was 30.30 +/- 4.80 years. There were two multiple pregnancies (one twin and one triplet) and 19 newborns were delivered alive. Rates of hypertensive disorders of pregnancy, preterm birth, intrauterine growth retardation, oligohydramnios, and intrauterine fetal demise were 36.4, 18.2, 13.6, 13.6, and 0%, respectively. Mean gestational age at birth was 37.25 +/- 2.40 weeks and mean birthweight was 2682.10 +/- 176.82 g. Median APGAR score was 8. Cesarean section rate was 50%. Regional anesthesia/analgesia was administered during 62.5% of the deliveries. Ten neonates were admitted to neonatal intensive care unit and eight neonates had neonatal respiratory complications. CONCLUSION: Appropriate management of pregnant women with TA within the framework of antenatal care programs and adopting a multidisciplinary approach are key to ensure successful outcomes. PMID- 30302545 TI - Regulation of MMP 2 and MMP 9 expressions modulated by AP-1 (c-jun) in wound healing: improving role of Lucilia sericata in diabetic rats. AB - AIMS: Lucilia sericata larvae have been successfully used on healing of wounds in the diabetics. However, the involvement of the extraction/secretion (ES) products of larvae in the treatment of diabetic wounds is still unknown. Activator protein 1 (AP-1) transcription, composed of c-jun and c-Fos proteins, has been shown to be the principal regulator of multiple MMP transcriptions under a variety of conditions, also in diabetic wounds. Specifically, MMP-2 and MMP-9's transcriptions are known to be modulated by AP-1. c-jun has been demonstrated to be a repressor of p53 in immortalized fibroblasts. The aim of the present study is to investigate the effects of L. sericata ES on the expression of AP-1 (c jun), p53, MMP-2, and MMP-9 in wound biopsies dissected from streptozotocin induced diabetic rats. METHODS: The expression levels of MMP-2, MMP-9, c-jun and p53 in dermal tissues were determined at days 0, 3, 7 and 14 after wounding, using immunohistochemical analysis and quantitative real-time PCR. RESULTS: The treatment with ES significantly decreased through inflammation-based induction of MMP-2 and MMP-9 expression levels in the wounds of diabetic groups, compared to control groups at the third day of wound healing. At the 14th day, there were dramatic decreases in expression of c-jun, MMP-9, and p53 in ES-treated groups, compared to the diabetic group (P < 0.001, P < 0.05 and P < 0.01, respectively). CONCLUSION: ES products of L. sericata may enhance the process of wound healing in phases of inflammation, proliferation, and re-epithelization, essentially via regulating c-jun expression and modulating MMP-2 and MMP-9 expressions. PMID- 30302546 TI - Urachal carcinoma: from gross specimen to morphologic, immunohistochemical, and molecular analysis. AB - Urachal carcinoma (UrC) is an exceedingly rare neoplasm that develops from the urachus, an embryologic remnant of the urogenital sinus and allantois. The most commonly encountered histologic subtype is adenocarcinoma. The aim of this study is to characterize a series of UrC by morphology, immunohistochemistry, and molecular analysis. We retrospectively investigated seven cases of UrCs and assessed patient symptoms, imaging, histologic features, immunohistochemical profile, molecular characteristics, pathologic stages, and type of treatment. Immunostaining for CK7, CK20, Muc-2, CDX2, GATA3, beta-catenin, and CK34betaE12 was carried out on each neoplasm and on seven non-neoplastic urachal remnants as the control group. Additionally, a mutational analysis was performed using the QIAact Actionable Insights Tumor Panel Kit, which analyzes KRAS, NRAS, KIT, BRAF, PDGFRA, ALK, EGFR, ERBB2, PIK3CA, ERBB3, ESR1, and RAF1. Our cohort comprised five females and two males with a mean age of 64 years. UrCs consisted of two mucinous cystadenocarcinomas and five invasive, non-cystic adenocarcinomas. Carcinoma antigen expression profile was positive for CK20 and negative for CK34betaE12 and GATA3 in all cases. Five of seven cases stained positively for Muc-2 and CDX2. On the contrary, non-neoplastic urachal remnants were immunoreactive for CK34betaE12, CK7, and GATA3. Mutational analysis gave a positive result in four out of seven (57.1%) cases. All four positive tumors showed RAS mutation and one an additional mutation in PIK3CA. Urachal tumors exhibit peculiar morphologic, immunohistochemical, and molecular features. Due to the advanced stage at presentation, individualized treatment should be undertaken. PMID- 30302547 TI - Nanomedicine in cancer stem cell therapy: from fringe to forefront. AB - Nanomedicine is the spin-off of modern medicine and nanotechnology and aims to prevent and treat diseases using nanoscale materials such as biocompatible nanoparticles and nanorobots. Targeted cellular and tissue-specific clinical applications with maximal therapeutic effects and insignificant side effects could be achieved by the pursuit of nanotechnology in medicine and healthcare regimen. The majority of conventional cancer therapies eliminate the cells of the tumor but not the cancer stem cells (CSCs). Conversely, the use of nanotechnology in CSC-based therapies is an emerging field of biomedical sciences. This article summarizes the recent trends and application of nanomedicine especially in CSC therapy along with its limitations. PMID- 30302548 TI - Novel spiral mapping catheter facilitates observation of the time-to-pulmonary vein isolation during cryoballoon ablation. AB - Observation of the time-to-pulmonary vein isolation (TTI) by a spiral mapping catheter has emerged as a valuable procedural parameter in cryoballoon pulmonary vein isolation (PVI). The 1st generation spiral mapping catheter (Achieve, SMC1) has been available as an 8-polar catheter with a distal loop diameter of 15 or 20 mm. The novel spiral mapping catheter (Achieve Advance, SMC2) was designed as a true guidewire and is available, in addition to the sizes of the SMC1, as a 10 polar mapping catheter with a distal loop diameter of 25 mm. Whether these novel features of SMC2 influence procedural characteristics of Cryo-PVI in comparison to SMC1 has not been reported. In this prospective cohort study 158 patients (age 65.1 +/- 12.4 years, female 39%, paroxysmal AF 60%) undergoing PVI with the 2nd generation cryoballoon were included. SMC1 was used in 57 patients (36%), whereas 101 patients (64%) underwent Cryo-PVI with the SMC2. All PVs (623/623, 100%) were isolated successfully. Mean procedure duration was 72.0 +/- 18.9 min in the SMC1 group and 74.4 +/- 19.1 min in the SMC2 group (p = 0.432). Mean fluoroscopy time was also not different between both study groups (SMC1 15.7 +/- 6.6 min, SMC2 15.7 +/- 7.3 min, p = 0.593). TTI was observed in 68.6% of pulmonary veins in the SMC1 group, whereas TTI observation rate was 82.6% in the SMC2 group (p < 0.001). Number of freezes (5.5 +/- 1.5 vs. 6.5 +/- 1.9; p = 0.001) and total freeze duration (14.1 +/- 4.5 vs. 17.6 +/- 5.6; p < 0.001) were increased in the SMC2 group. SMC2 significantly increases TTI observation rate during Cryo-PVI. Procedure duration and fluoroscopy time are similar and number of freezes and total freeze duration are increased compared to PVI with SMC1 due to decreased stability and maneuverability of SMC2. PMID- 30302549 TI - Sunflower oil transesterification with methanol using immobilized lipase enzymes. AB - The transesterification of sunflower oil with methanol, using immobilized lipase enzymes as catalysts, was studied. The process was carried out in a semi continuous mode. Temperature (30-50 degrees C), methanol flow (0.024-0.04 ml/min), kind of enzyme (Lipozyme 62350, Lipozyme TL-IM, Novozym 435 and Pseudomonas cepacia Sol-Gel-AK) and enzyme concentrations (1.25-10% by weight) were the operating variables. The final product was characterized by the EN 14214 standard. All the parameters, except for cold filter plugging point, were similar to a diesel fuel. For low methanol flows, reaction rate was proportional to methanol concentration. High flows caused catalyst deactivation. Novozyme 435, Lipozyme TL-IM and Lipozyme 62350 showed similar maximum reaction rates, but Novozyme 435 was more resistant to deactivation. Pseudomonas cepacia hardly obtained 1% conversion. The catalyst concentration, up to 2.5%, had a positive effect on the reaction rate and conversion. The optimum temperature was 40 degrees C. The initial reaction rate was in line with the Arrhenius law, up to 50 degrees C. By differential and integral methods, the Michaelis-Menten, competitive inhibition and ping-pong bi-bi kinetic parameters were determined. The transesterification of sunflower oil in a semi-continuous regime of alcohol improved the results, compared to the discontinuous regime, and those were similar to the obtained ones in a discontinuous regime with step-by-step methanol addition. The lipase that showed the best yield and higher resistance to deactivation was Novozym 435. The kinetic models that forecast the deactivation of lipases by an inhibitor described the experimental behavior properly. PMID- 30302550 TI - Characterisation of Stramenopile-specific mastigoneme proteins in Phytophthora parasitica. AB - Mastigonemes, tripartite tubular hairs on the anterior flagellum of Phytophthora zoospores, are instrumental for disease dissemination to new host plants. A previous study showed that PnMas2 was part of the tubular shaft of Phytophthora parasitica mastigonemes. In the current study, genes encoding two related proteins, PnMas1 and PnMas3, were identified in the genome of P. parasitica. PnMas1 interacts with PnMas2 and also occurs along the mastigoneme shaft. RNA-Seq analyses indicate that PnMas1 and PnMas2 genes have similar expression profiles both in vitro and in planta but that PnMas3 is expressed temporally prior to PnMas1 and PnMas2 during asexual development and plant infection. Immunocytochemistry and GFP-tagging document the occurrence of all three PnMas proteins within the specialised compartments of the ER during mastigoneme formation, but only PnMas1 and PnMas2 occur in mature mastigonemes on the flagellar surface. Anti-PnMas1 and anti-PnMas2 antibodies co-labelled two high molecular-weight (~400 kDa) protein complexes in native gels but anti-PnMas3 antibodies labelled a 65 kDa protein complex. Liquid chromatography-mass spectrometry analysis identified PnMas1 and PnMas2 but not PnMas3 in flagellar extracts. These results suggest that PnMas3 associates with mastigonemes during their assembly within the ER but is not part of mature mastigonemes on the anterior flagellum. Phylogenetic analyses using homologues of Mas genes from the genomes of 28 species of Stramenopiles give evidence of three Mas sub-families, namely Mas1, Mas2 and Mas3. BLAST analyses showed that Mas genes only occur in flagellate species within the Stramenopile taxon. PMID- 30302551 TI - The similarity of crawling mechanisms in aquatic and terrestrial gastropods. AB - Crawling gastropods are unique models for studying the functioning of smooth muscles and ciliated epithelia, since they cover the foot sole and are involved in locomotion, allowing for direct investigation. Two types of crawling are known: creeping by muscular waves in terrestrial gastropods such as Helix and siliary gliding in aquatic gastropods such as Lymnaea. It was found that the smooth muscles that underlie the ciliated epithelium in Lymnaea are involved in gliding and contribute significantly to fast crawling. Thus, the locomotor apparatus is fundamentally the same in both snails and the difference between crawling reflects an adaptation to a habitat. The control of crawling speed is also the same. Tonic contraction, relaxation, and rhythmic contractions are involved in this control. During a locomotor episode, the sole length and crawling speed spontaneously change and directly correlate with each other via the contraction force of the muscle cells in the locomotory waves. Dopamine, unlike ergometrine, decreases the sole length and crawling speed. Serotonin stimulates, increases crawling and determines the number of muscle cells involved in the locomotory waves for each locomotor episode. This control (taking into account heterogeneity) apparently might exist in any other phasic smooth muscle, including vertebrates. PMID- 30302552 TI - Experienced trauma team leaders save the lives of multiple-trauma patients with severe head injuries. AB - The trauma team leader is a professional who receives and treats trauma patients. We aimed to evaluate whether or not the seniority of a qualified trauma team leader was a prognostic factor for multiple-trauma patients managed by a trauma team. This was a retrospective cohort study conducted at a Level I Trauma Center in North Taiwan. From January 2009 to December 2013, 284 patients were randomly assigned to one of two trauma team leaders (junior and senior leaders) on duty, irrespective of the seniority of the qualified trauma team leader. All parameters were collected and compared between these two groups. In the subgroup of multiple trauma patients with Glasgow Coma Scale (GCS) <= 8, there were significant differences in the injury severity score, revised trauma score, and seniority of the leader between the alive and dead groups. A multivariate logistic regression analysis showed that the seniority of the trauma team leader was an important mortality risk factor [odds ratio (OR): 14.529, 95% confidence interval (CI) 1.683-125.429, p = 0.015] in patients with GCS <= 8. However, in patients with GCS > 8, age was the only independent risk factor [OR: 1.055, 95% CI 1.023-1.087, p = 0.001]. The seniority of the qualified trauma leader is important for teamwork, organization, and efficiency, all of which play an important role in improving the survival outcome of patients with GCS <= 8. PMID- 30302554 TI - Adhesion-Related Immunomodulatory Activity of the Screened Lactobacillus plantarum from Sichuan Pickle. AB - Lactic acid bacteria are the majority fermentation starter in the traditional fermented foods. In this research, a promising Lactobacillus plantarum was isolated from Sichuan pickle and its adhesion properties were analyzed in simulated gastrointestinal fluid with different methods. Meanwhile, the immunomodulatory effect of this strain was also evaluated in the Caco-2 cells. Results found that adhesion-related mub genes and other genes like lsp and tuf were upregulated in different culture times. Furthermore, L. plantarum cultured at alkaline environment revealed some anti-inflammation activity through inhibited expression of cytokine IL-8 and increased expression of anti inflammatory cytokine IL-10 in Caco-2 cells. The texture of yogurt after fermented by this kind of isolated strain was also investigated, which provides the foundation for the further development and application of this kind of strain in food production. More investigations need to be carried out to determine whether this probiotic contributes to regulation of intestinal flora and prevention of gut inflammation. PMID- 30302553 TI - A specific allele of MYB14 in grapevine correlates with high stilbene inducibility triggered by Al3+ and UV-C radiation. AB - KEY MESSAGE: The structural differences of MYB14 promoter in two grapevine genotypes affect the expression of MYB14 and stilbene synthesis in response to Al3+ and UV-C radiation. Grapevines provide an important fruit crop worldwide, but production is often limited by pathogen infection. Stilbenes, a class of secondary metabolite, represent phytoalexins that contribute to defence against pathogens in many plants, including grapevine. It is known that the transcription factors MYB14 and MYB15 are required for the activation of the promoters of resveratrol synthase to regulate stilbene biosynthesis. In the current study, we observed that stilbene levels were more highly induced by Al3+ and UV-C radiation treatments in the cultivar Vitis labrusca 'Concord' than in the cultivar V. vinifera 'Cabernet Sauvignon'. We investigated whether genetic/structural variations in the MYB14 and MYB15 promoters between these two representative genotypes are responsible for the differences in stilbene accumulation. Significant differences in the structure and activity of the promoter of MYB14, but not MYB15 were identified between the two genotypes, following heterologous expression in Nicotiana benthamiana system and treatments with Al3+ and UV-C. Hydrogen peroxide (H2O2) was detected in Concord soon after the stress treatments, but after diphenyleneiodonium chloride pre-treatment, the expressing level of VlMYB14, the promoter activity of VlMYB14 and the accumulation of stilbenes was significantly reduced. A model is presented where the induction of MYB14 contributes to stilbene accumulation in Concord following Al3+ and UV-C treatments involving reactive oxygen species (ROS) production as an early signal.

AB - Vip3Aa (vegetative insecticidal protein) secreted by Bacillus thuringiensis (Bt) is highly toxic to lepidopteran insects. The Bt isolate M190 produces Vip3Aa35 at high concentrations, and Vip3Aa35 was found to be very effective against Spodoptera exigua. Unfortunately, the use of Vip3Aa35 in pest control is limited by its short shelf life when stored at high temperatures, retaining activity for only 1 month at 37 degrees C. To find a more stable alternative, we screened 500 isolates of Bt collected from various locations in Thailand and discovered Bt isolate 294 which produced large amounts of Vip3Aa64 that exhibited high toxicity against S. exigua but could be stored at 37 degrees C for up to 3 months. Vip3Aa35 and Vip3Aa64 have only nine amino acid differences between them, with six of those residues being located at the C terminus. Vip3Aa35 and Vip3Aa64 chimeras revealed that the C-terminal sequence is important for the retained larvicidal activity observed with Vip3Aa64. Various single amino acid substitutions were created to identify the key amino acids responsible for this stability. A single residue, Tyr776, was found to be solely responsible, with the Vip3Aa35:N776Y acquiring thermostability similar to Vip3Aa64 while the Vip3Aa64:Y776N exhibited Vip3Aa35-like thermostability. PMID- 30302556 TI - Is ultrasonographic enthesitis evaluation helpful for diagnosis of non radiographic axial spondyloarthritis? AB - The aim of this study is to evaluate the diagnostic utility of ultrasonographic enthesitis assessment in patients with non-radiographic axial spondyloarthritis (nr-axSpA) and to compare different sonographic scoring methods. Patients with nr axSpA (n = 30) and mechanical back pain (MBP) (n = 30) were enrolled in the study with standardized clinical criteria. For both of the groups, a total of 18 entheses were evaluated in each patient with B mode ultrasound and power Doppler by a sonographer who is blinded to initial clinical and radiological assessments. Glasgow Ultrasound Enthesitis Scoring System (GUESS), Madrid Sonographic Enthesitis Index (MASEI) and D'Agostino grading system were performed. Intra rater and inter-rater reliability analyses were evaluated with the intraclass correlation coefficient (ICC). There was at least one enthesitis in 96.7% of patients with nr-axSpA. Median values of the number of enthesitis were 5 in nr axSpA and 0 in MBP. Mean GUESS total scores were 0.9 in MBP and 4.5 in nr-axSpA. Mean MASEI total scores were 2.3 and 10.5, respectively. The sensitivities were 96.7% and 93.3% for GUESS and MASEI while the detected specificities were 80% for both methods. For Intra-rater reliability analysis, ICC was calculated as 0.981 for GUESS and 0.975 for MASEI, while it was calculated as 0.964 and 0.962 for inter-rater reliability analysis. Thus, evaluation of enthesitis with ultrasound is a reliable, helpful tool for the distinction of patients with nr-axSpA from patients with MBP. We favored the use of MASEI because of assessing upper extremity, using power Doppler and having a correlation with disease activity. PMID- 30302557 TI - Inflammatory reaction, clinical efficacy, and safety of bacterial cellulose wound dressing containing silk sericin and polyhexamethylene biguanide for wound treatment. AB - Bacterial cellulose wound dressings containing silk sericin and PHMB (BCSP) were developed in our previous studies. It had good physical properties, efficacy, and safety. For further use as a medical material, this dressing was investigated for its efficacy and safety in split-thickness skin graft (STSG) donor-site wound treatment compared to Bactigras(r) (control). Moreover, the inflammatory responses to both dressings were also deeply investigated. For in vivo study, expressions of anti-inflammatory cytokines were intensely considered in the tissue interfacing area. The result showed that IL-4 and TGF-beta from BCSP treated tissue had advantages over Bactigras(r)-treated tissue at 14 and 21 days post-implantation. For clinical study, a single-blinded, randomized controlled study was generated. The half of STSG donor site wound was randomly assigned to cover with BCSP or Bactigras(r). Twenty-one patients with 32 STSG donor site wounds were enrolled. The results showed that wound-healing time was not significantly different in both dressings. However, wound quality of BCSP was better than Bactigras(r) at healing time and after 1 month (p < 0.05). The pain scores of BCSP-treated wound were statistically significant lower than Bactigras(r)-treated wound (p < 0.05). No sign of infection or adverse event was observed after treatment with both dressings. In conclusion, the inflammation responses of the dressing were clearly clarified. The advantages of BCSP were wound-quality improvement, pain reduction, and infection protection without adverse events. It was fit to be used as the alternative treatment of STSG donor site wound. PMID- 30302558 TI - Ezetimibe in high-risk, previously treated statin patients: a systematic review and network meta-analysis of lipid efficacy. AB - PURPOSE: While statins are used as first-line treatments for high-risk patients with hypercholesterolemia, statin monotherapy is often insufficient to achieve target low-density lipoprotein cholesterol (LDL-C) levels. Second-line treatment options include up-titration of statin dose, switching to a more potent statin, or combination therapy, e.g., with ezetimibe. The aim of this study was to evaluate the efficacy of adding ezetimibe to simvastatin, atorvastatin, or rosuvastatin monotherapy versus doubling the dosage or switching to a higher potency statin in a population of patients with hypocholesterolemia at high risk of cardiovascular disease (CVD) and who had been previously treated with a statin. METHODS: A systematic literature search was performed and evidence bases were established for populations of atorvastatin-, simvastatin-, and rosuvastatin experienced patients using eligible randomized controlled trials (RCTs). Based on the available data, we constructed networks of evidence and conducted a Bayesian network meta-analysis (NMA) within each statin population. The primary outcome of interest was percent change from baseline in LDL-C. Changes in total cholesterol were explored as a secondary outcome. FINDINGS: Across all patient populations, 35 RCTs were identified and included in the evidence base. Among patients on simvastatin therapy, the addition of ezetimibe resulted in a mean difference (MD) in LDL-C of - 13.62% (95% CrI - 19.99, - 6.91; see table below) compared to doubling the starting dose of simvastatin. In the population of patients on atorvastatin therapy, the addition of ezetimibe resulted in an MD in LDL-C of - 14.71% (95% CrI - 16.46, - 12.95) compared to doubling the starting dose of atorvastatin. The addition of ezetimibe to rosuvastatin resulted in an MD in LDL C of - 14.96% (95% CrI - 17.79, - 12.11), compared to doubling the starting rosuvastatin dose. Similar trends were observed for changes in total cholesterol. IMPLICATIONS: Given the available data, the addition of ezetimibe to ongoing simvastatin, atorvastatin, or rosuvastatin monotherapy offers greater reduction in LDL-C among patients at high risk of CVD compared to doubling the initial statin dose.

AB - Standardized analysis of histological findings in a routinely stained section without knowledge of the clinical picture ("blind fashion") allows an objective assessment of the pathological changes. In inflammatory dermatoses diagnostic algorithms and criteria have been proven. They follow defined main inflammatory patterns, the composition of the inflammatory infiltrate and additional criteria. Taking into account the stage of development and the possibility of collision phenomena, this approach will give a histological diagnosis, or at least a limited number of differential diagnoses. However, the final diagnosis always results from the synopsis of the clinical picture and additional parameters. The modern development of algorithms and new histological criteria are outlined in autoimmune dermatoses, autoinflammatory syndromes, drug reactions and genodermatoses.

Amyloidoses are caused by the deposition of amyloid and may occur as cerebal and extracerebral diseases. A total of 35 different amyloid proteins have been identified. The Amyloid Registry Kiel was founded in 2009 at the Department of Pathology of the Christian-Albrechts-University Kiel. It currently houses more than 6700 cases of diverse anatomical origin with histologically confirmed amyloid and amyloidosis. This large series of cases provides unique insights into an otherwise rare disease. This includes the validation of novel dyes for the histological recognition and diagnosis of amyloid (luminescent conjugated polythiophenes), the in-depth analysis of amyloid associated with carpal tunnel syndrome, the distribution pattern of diverse amyloids in biopsies of the gastrointestinal tract and the prognostic significance of immunoglobulin light chain-derived AL amyloid load in cardiac biopsies. Finally, the application of MALDI (matrix-assisted laser desorption/ionization) mass spectrometry imaging provided valuable insights into the complexity of amyloid deposits, which consist of a diagnostic disease specific and amyloid-specific protein/peptide mixture.

AB - Core-shell structured particles were prepared from carbonized zeolitic imidazolate frameworks (ZIFs) and reduced graphene oxide (rGO). The particles possess a nitrogen content of up to 10.6%. The loss of nitrogen from the ZIF is avoided by utilizing the reduction and agglomeration of graphene oxide with suitable size (>2 MUm) during pyrolysis. The resulting carbonized ZIF@rGO particles were deposited on a glassy carbon electrode to give an amperometric sensor for H2O2, typically operated at a voltage of -0.4 V (vs. Ag/AgCl). The sensor has a wide detection range (from 5 * 10-6 to 2 * 10-2 M), a 3.3 MUM (S/N = 3) detection limit and a 0.272 MUA.MUM-1.cm-2 sensitivity, much higher than that of directly carbonized ZIFs. The sensor material was also deposited on a screen printed electrode to explore the possibility of application. Graphical abstract Nitrogen doped carbon (NC) derived from carbonized zeolitic imidazolate frameworks is limited because of low nitrogen content. Here, nitrogen-rich NC@reduced graphene oxide (rGO) core-shell structured particles are described. The NC@rGO particles show distinctly better H2O2 detection performance than NC. PMID- 30302566 TI - Development and validation of a sensitive LC-MS/MS assay for the quantification of anserine in human plasma and urine and its application to pharmacokinetic study. AB - Carnosine (beta-alanyl-L-histidine) and its methylated analogue anserine are present in relevant concentrations in the omnivore human diet. Several studies reported promising therapeutic potential for carnosine in various rodent models of oxidative stress and inflammation-related chronic diseases. Nevertheless, the poor serum stability of carnosine in humans makes the translation of rodent models hard. Even though anserine and carnosine have similar biochemical properties, anserine has better serum stability. Despite this interesting profile, the research on anserine is scarce. The aim of this study was to explore the bioavailability and stability of synthesized anserine by (1) performing in vitro stability experiments in human plasma and molecular modelling studies and by (2) evaluating the plasma and urinary pharmacokinetic profile in healthy volunteers following different doses of anserine (4-10-20 mg/kg body weight). A bio-analytical method for measuring anserine levels was developed and validated using liquid chromatography-electrospray mass spectrometry. Both plasma (CMAX: 0.54-1.10-3.12 uM) and urinary (CMAX: 0.09-0.41-0.72 mg/mg creatinine) anserine increased dose-dependently following ingestion of 4-10-20 anserine mg/kg BW, respectively. The inter-individual variation in plasma anserine was mainly explained by the activity (R2 = 0.75) and content (R2 = 0.77) of the enzyme serum carnosinase-1. Compared to carnosine, a lower interaction energy of anserine with carnosinase-1 was suggested by molecular modelling studies. Conversely, the two dipeptides seems to have similar interaction with the PEPT1 transporter. It can be concluded that nutritionally relevant doses of synthesized anserine are well absorbed and that its degradation by serum carnosinase-1 is less pronounced compared to carnosine. This makes anserine a good candidate as a more stable carnosine-analogue to attenuate chronic diseases in humans. PMID- 30302567 TI - A needle-like reusable surface-enhanced Raman scattering substrate, and its application to the determination of acetamiprid by combining SERS and thin-layer chromatography. AB - A micro surface-enhanced Raman scattering (SERS) substrate has been fabricated by electrochemical deposition of dendrite-like gold on carbon fiber needles (Au CFNs). Scanning electron microscopy and energy dispersive spectroscopy were used to confirm the presence of the gold nanostructure on the CFNs. This substrate has a Raman scattering enhancement factor as high as 3.3 * 10^7 when using rhodamine 6G as the reporter molecule. The high SERS sensitivity is attributed to the massive hotspots on gold bulges that enhance the local surface plasmon resonance. The Au-CFN substrate was reproduced 10 times after electrochemically wiping off the analytes from the needle-like electrode. The substrate has attractive features such as convenient sampling, low sample dosage, and minimal invasion. It was applied, in combination with thin-layer chromatography, for the determination of acetamiprid on vegetables. The result was more accurate because the sample information of both the surface and the bulk can be obtained at the same time after inserting the tip of this needle substrate into the TLC plate. The limit of detection for acetamiprid is 0.05 MUg?mL-1 and the linear range is 0.1-10 MUg?mL 1. Graphical abstract A reusable micro needle-like SERS substrate was fabricated and applied for pesticide residue analysis. The SERS signal of acetamiprid can be acquired on the tip of this micro needle-like Au-CFN substrate. This substrate can be reused for 10 times. PMID- 30302568 TI - A voltammetric assay for microRNA-25 based on the use of amino-functionalized graphene quantum dots and ss- and ds-DNAs as gene probes. AB - The authors describe a DNA based voltammetric assay for the cancer biomarker microRNA-25. A glassy carbon electrode (GCE) was modified with amino functionalized graphene quantum dots and used as an amplifier of electrochemical signals. p-Biphenol is introduced as a new electroactive probe with a fairly low working potential of 0.3 V (vs. Ag/AgCl). The stages of fabricating the electrode were characterized by cyclic voltammetry and electrochemical impedance spectroscopy. ss-Probe DNA was immobilized on the modified GCE and then exposed to a sample containing microRNA-25. The results indicated that the electrode can distinguish complementary microRNA-25 from a single-base mismatch. The increase in the electrochemical response of PBP and the positive shift in the potential peak indicate that PBP is intercalated between two strands. Under optimized experimental conditions, the current of the electrode increases linearly with the logarithm of the microRNA-25 concentration in the range from 0.3 nM to 1.0 MUM, and the detection limit is 95.0 pM. The assay was successfully employed to the determination of microRNA-25 in spiked human plasma. Graphical abstract A novel electrochemical nanogenosensor is introduced for simple and sensitive determination of microRNA-25, as a biomarker, based on amino-functionalized graphene quantum dots (as a surface modifier) and p-biphenol (as an electroactive label). PMID- 30302569 TI - Ultrasensitive determination of thrombin by using an electrode modified with WSe2 and gold nanoparticles, aptamer-thrombin-aptamer sandwiching, redox cycling, and signal enhancement by alkaline phosphatase. AB - A sensitive aptamer/protein binding-triggered sandwich assay for thrombin is described. It is based on electrochemical-chemical-chemical redox cycling using a glassy carbon electrode (GCE) that was modified with WSe2 and gold nanoparticles (AuNPs). The AuNPs are linked to thrombin aptamer 1 via Au-S bonds. Thrombin is first captured by aptamer 1 and then sandwiched through the simultaneous interaction with AuNPs modified with thrombin-specific aptamer 2 and signalling probe. Subsequently, the DNA-linked AuNP hybrids result in the capture of streptavidin-conjugated alkaline phosphatase onto the modified GCE through the specific affinity reaction for further signal enhancement. As a result, a linear range of 0-1 ng mL-1 and a detection limit as low as 190 fg mL-1 are accomplished. The specificity for thrombin is excellent. Conceivably, this strategy can be easily expanded to other proteins by using the appropriate aptamer.

AB - A computational study was carried out to characterize the hydrogen-bonded dimers of Zoledronate (ZOL), which is used widely in treating skeletal diseases. The stable conformations, hydrogen bonding interactions, IR spectra, thermodynamic properties, and electronic characteristics of nine possible ZOL dimers were studied using density functional theory (DFT) at the B3LYP/6-311++G** level. The stability of dimers was determined according to the analyses of total electronic energies and hydrogen bonding interactions. The results showed that both the number and intensity of hydrogen bonds played an important role in determining the stability order of dimers, and the hydrogen bonding interactions in dimers resulted in a red shift of hydroxyl vibration with a corresponding increase in intensity. The calculated thermodynamic properties illustrated that the dimerization process can take place spontaneously at room temperature. Natural bond orbital and atoms in molecules analyses revealed that the nature of hydrogen bonding interactions was attributed to the interactions from lone pair orbital n(A) to the antibonding orbital sigma*(D-H), and the interactions were closed shell interactions in hydrogen-bonded dimers of ZOL.

AB - PURPOSE OF REVIEW: Antiepileptic drugs are frequently administered to patients with HIV infection or in recipients of organ transplants. The potentially serious drug-drug interactions between the "classic" antiepileptic drugs, antiretrovirals, and immunosuppressants have been extensively studied. Evidence based information on the second and third generation of antiepileptic drugs is almost non-existent. The purpose of this review is to analyze the pharmacokinetic profile of these newer agents to assess their potential for drug interactions with antiretrovirals and immunosuppressants. RECENT FINDINGS: As a group, the newer generations of antiepileptic drugs have shown a more favorable drug interaction potential compared to the "classic" ones. A group of moderate enzyme inducing drugs includes eslicarbazepine acetate, oxcarbazepine, rufinamide, and topiramate. These drugs are not as potent inducers as the "classic" drugs but may potentially decrease the serum concentrations of some antiretrovirals and immunosuppressants. Antiepileptic drugs with no or minimal enzyme-inducing properties include brivaracetam, gabapentin, lacosamide, lamotrigine, levetiracetam, perampanel, pregabalin, and vigabatrin. The newer generations of antiepileptic drugs have expanded the therapeutic options in patients with HIV infection or organ transplants. PMID- 30302571 TI - Advanced Imaging for Barrett's Esophagus and Early Neoplasia: Surface and Subsurface Imaging for Diagnosis and Management. AB - PURPOSE OF REVIEW: Esophageal adenocarcinoma bears one of the fastest rising incidence of any cancers and generally arises in the setting of gastroesophageal reflux and Barrett's esophagus. However, early detection of neoplasia can be challenging since most patients are asymptomatic until they progress to more advanced and less curable stages, and early dysplastic lesions can be small, multifocal, and difficult to detect. Clearly, new imaging tools are needed in light of sampling error associated with random biopsies, the current standard of practice. RECENT FINDINGS: Advances in endoscopic imaging including virtual chromoendoscopy, confocal laser endomicroscopy, and subsurface imaging with optical coherence tomography have ushered in a new era for detecting subtle neoplastic lesions. Moreover, in light of esophagus-sparing treatments for neoplastic lesions, such tools are likely to guide ablation and follow-up management. While there is no ideal single imaging modality to facilitate improved detection, staging, ablation, and follow-up of patients with dysplastic Barrett's esophagus, new advances in available technology, the potential for multimodal imaging, and the use of computer-aided diagnosis and biomarkers all hold great promise for improving detection and treatment. PMID- 30302573 TI - Theoretical investigation of the regioselective ring opening of 2 methylaziridine. Lewis acid effect. AB - The formation of substituted 1,2-diamines via the regiospecific nucleophilic ring opening of 2-methylaziridine with methylamine was performed by nucleophilic attack at aziridine carbon atoms. A detailed theoretical study was investigated by density functional theory (DFT) at the B3LYP level and second order Moller Plesset perturbation theory (MP2) by using the 6-311G(d,p) basis set. The third Grimme correction term (D3) was used to take into account weak interactions. Solvent effects were computed in methanol and dimethylsulfoxide using the polarizable continuum model (PCM). Emphasis was placed on the ring opening mechanisms of neutral aziridines and aziridinium ions obtained through N complexation with the BF3 Lewis acid. Moreover, the effect of substituent groups on the regioselectivity of the ring opening was investigated. The nucleophilic attack was carried out via two pathways (frontside attack M1 and backside attack M2) where activation barriers proved the preference for ring opening through the backside attack at the C3 aziridine carbon atom. The obtained results showed that the frontside attack with methylamine takes place along a concerted mechanism that leads to formation of products through one transition state. However, the backside attack is carried via a stepwise process in which the methylamine attack takes place in an SN2 fashion where the leaving group is the ring nitrogen. It first conduces a ring opening considered as the rate-determining step followed by formation of a zwitterionic intermediate. This latter undergoes a rotation to allow the proton transfer step and finally leads to formation of the thermodynamic products. PMID- 30302574 TI - Investigation of ultra-low insertion speeds in an inelastic artificial cochlear model using custom-made cochlear implant electrodes. AB - PURPOSE: Latest research on cochlear implantations focuses on hearing preservation during insertion of the implant's electrode array by reducing insertion trauma. One parameter which may influence trauma is insertion speed. The objective of this study was to extend the range of examined insertion speeds to include ultra-low velocities, being lower than manually feasible, and investigate whether these reduce insertion forces. METHODS: 24 custom-made cochlear implant test samples were fabricated and inserted into an artificial scala tympani model using 12 different insertion speeds while measuring the resulting insertion forces. Three commercially available slim straight electrode carriers were inserted using the same setup to analyze whether the results are comparable. RESULTS: Insertions of the test samples using high insertion speeds (2.0/2.8 mm/s) showed significantly higher insertion forces than insertions done with low insertion speeds (0.2 mm/s) or ultra-low insertion speeds (< 0.1 mm/s). The insertions with commercial slim straight electrode arrays showed significantly reduced insertion forces when using a low insertion speed as well. CONCLUSIONS: Slow insertions showed significantly reduced insertion forces. Insertion speeds which are lower than manually feasible showed even lower insertion forces. PMID- 30302576 TI - The Prevalence of PTSD Symptoms and Depressive Symptoms and Related Predictors in Children and Adolescents 3 Years After the Ya'an Earthquake. AB - The objectives of this study were to investigate the prevalence of post-traumatic stress disorder (PTSD) symptoms and depressive symptoms in teenage survivors three years after the Ya'an earthquake to assess the differences between left behind (LBC) and non-left-behind (non-LBC) children, and to explore predictors for PTSD symptoms and depressive symptoms. The participants were assessed using children's revised impact of event scale (CRIES) and short mood and feelings questionnaire (SMFQ), after which t tests, Chi square tests, and a multivariate logistic regression were conducted to examine the differences in the LBC and identify the associated predictors. It was found that the PTSD and depressive symptom prevalences were 13.10% and 20.75%, with the LBC having a significantly higher prevalence than the non-LBC. The PTSD and depression symptoms tended to be highly comorbid (r = .52, p < .001). Being female, being aged less than 15, having siblings, being an LBC, and having higher exposure were found to be associated with PTSD and depressive symptoms. PMID- 30302575 TI - Association of benign paroxysmal positional vertigo with vitamin D deficiency: a systematic review and meta-analysis. AB - BACKGROUND AND OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is an idiopathic recurrent inner ear illness that is caused most often by an imbalance in the metabolism of calcium carbonate crystals (otoconia) inside the semicircular canals, in which the otoconia begin to circulate freely after being dislodged from the basic structure. The underlying etiology of this imbalance has not yet been well established; however, a few recent articles have revealed that vitamin D level abnormality in these patients might play a role. Therefore, we conducted the current systematic review analysis to explore potential associations of vitamin D level with the occurrence as well as the recurrence of BPPV disease. METHODS: A comprehensive literature search was conducted using different databases to retrieve all of the articles that have evaluated possible associations, irrespective of the study design. Then, we reported different vitamin D3 levels from BPPV groups and control groups to estimate the standardized mean difference (SMD) between the BPPV and control groups. We also calculated the effect size of each study under the random effects statistical model. RESULTS: Of the 703 studies that we identified, only 37 studies were found to be potential for our analysis, and of these, only seven met our predetermined criteria. Two meta-analyses were conducted with respect to the occurrence and the recurrence of BPPV. When the BPPV cases were compared to the controls (free of BPPV disease), there was an insignificant reduction in vitamin D level among the diseased groups (SMD = - 2.20; 95% CI - 6.66 to 2.26). In contrast, when the recurrent BPPV groups were compared with the non-recurrent BPPV groups, the statistical analysis showed significantly lower level of vitamin D among the recurrence BPPV groups (SMD = - 4.47; 95% CI - 7.55 to - 1.29). CONCLUSION: Although a negative vitamin D imbalance has been reported among some BPPV patients, this review analysis failed to establish a relationship between the occurrence of BPPV and low vitamin D level. However, low vitamin D level was significantly evident among patients with recurrent episodes of BPPV. PMID- 30302577 TI - Enhancing Outcomes of Low-Intensity Parenting Groups Through Sufficient Exemplar Training: A Randomized Control Trial. AB - Low-intensity parenting groups, such as the Triple P-Positive Parenting Program Discussion Groups, appear to be a cost-effective intervention for child conduct problems. Several studies evaluating a Triple P Discussion Group on disobedience found promising results for improving child and parent outcomes. However, a sufficient exemplar training approach that incorporates generalization promotion strategies may assist parents to more flexibly apply positive parenting principles to a broader range of child target behaviors and settings, leading to greater change. We compared the effects of sufficient exemplar training to an existing narrowly focused low-intensity intervention. Participants were 78 families with a 5-8 year-old child. Sufficient exemplar training resulted in more robust changes in child behavior and superior outcomes for mothers on measures of parenting behavior, parenting self-efficacy, mental health, and perceptions of partner support at post-intervention and 6-month follow-up. These results indicate that teaching sufficient exemplars may promote generalization leading to enhanced intervention outcomes. PMID- 30302578 TI - Effective temperature of active fluids and sheared soft glassy materials. AB - The dynamics within active fluids, driven by internal activity of the self propelled particles, is a subject of intense study in non-equilibrium physics. These systems have been explored using simulations, where the motion of a passive tracer particle is followed. Similar studies have been carried out for a soft glassy material that is driven by shearing its boundaries. In both types of systems the non-equilibrium motion have been quantified by defining a set of "effective temperatures", using both the tracer particle kinetic energy and the fluctuation-dissipation relation. We demonstrate that these effective temperatures extracted from the many-body simulations fit analytical expressions that are obtained for a single active particle inside a visco-elastic fluid. This result provides testable predictions and suggests a unified description for the dynamics inside active systems. PMID- 30302579 TI - Genotoxic effects of PM10 and PM2.5 bound metals: metal bioaccessibility, free radical generation, and role of iron. AB - The present study was undertaken to examine the possible genotoxicity of ambient particulate matter (PM10 and PM2.5) in Pune city. In both size fractions of PM, Fe was found to be the dominant metal by concentration, contributing 22% and 30% to the total mass of metals in PM10 and PM2.5, respectively. The speciation of soluble Fe in PM10 and PM2.5 was investigated. The average fraction of Fe3+ and Fe2+ concentrations in PM2.5 was 80.6% and 19.3%, respectively, while in PM2.5 this fraction was 71.1% and 29.9%, respectively. The dominance of Fe(III) state in both PM fractions facilitates the generation of hydroxyl radicals (.OH), which can damage deoxyribose nucleic acid (DNA), as was evident from the gel electrophoresis study. The DNA damage by .OH was supported through the in silico density functional theory (DFT) method. DFT results showed that C8 site of guanine (G)/adenine (A) and C6 site of thymine (T)/cytosine (C) would be energetically more favorable for the attack of hydroxyl radicals, when compared with the C4 and C5 sites. The non-standard Watson-Crick base pairing models of oxidative products of G, A, T and C yield lower-energy conformations than canonical dA:dT and dG:dC base pairing. This study may pave the way to understand the structural consequences of base-mediated oxidative lesions in DNA and its role in human diseases.

MeCSV differs from other tenuiviruses by its number of genomic fragments, by being readily mechanically transmissible, and by infecting only dicotyledonous hosts. MeCSV should thus be considered a member of a tentative new species related to tenuiviruses. PMID- 30302580 TI - Shear wave elasticity imaging for residual endoleak and thrombus characterisation after endoleak embolisation following endovascular aneurysm repair: a canine animal study. AB - BACKGROUND: To evaluate residual endoleak and thrombus organisation with shear wave imaging (SWI) after endoleak embolisation through an animal study. METHODS: This prospective experimental study involved eight dogs with creation of 16 iliac aneurysms and type I endoleak after endovascular aneurysm repair (EVAR). Embolisation agents were injected into the sac to seal endoleak. SWI and colour flow Doppler ultrasound (DUS) were performed at implantation, one week, and one and three months after implantation; for three dogs, SWI and DUS were also performed six months after implantation. Digital subtraction angiography and contrast-enhanced computed tomography were performed at sacrifice. Macroscopic and histopathological analyses were processed to identify regions of interest (ROIs) for endoleak, fresh thrombus, organised thrombus and embolisation agent, where SWI elasticity moduli were compared. RESULTS: At sacrifice, nine aneurysms had residual endoleak, while seven were sealed. Ten had a fresh and 15 had an organised thrombus. SWI was able to detect all endoleaks, including two cases undetected with DUS. Elasticity moduli of 0.2 kPa +/- 0.1 kPa (mean +/- SD), 9.5 kPa +/- 3.3 kPa, 48.1 kPa +/- 21.3 kPa and 44.9 kPa +/- 23.7 kPa were found in the ROIs positioned in endoleaks, fresh thrombi, organised thrombi and embolisation agent, respectively. Elasticity values of endoleak and fresh thrombus were lower than those of organised thrombi and embolisation agent (p < 0.001). Stiffness of fresh thrombus at one week (8.7 kPa +/- 3.6 kPa) increased at three months (30.2 kPa +/- 13.8 kPa), indicating thrombus maturation (p < 0.001). CONCLUSIONS: In a dog model of iliac EVAR, SWI was able to identify endoleak, thrombus maturation and embolising agents after endoleak embolisation.

AB - In recent years, avian-origin H10 influenza viruses have proved capable of infecting human beings, and they pose a potential public health threat. Seven H10 avian influenza viruses (AIVs), H10N3 (n = 2), H10N7 (n = 1), and H10N8 (n = 4), were isolated from chickens in Zhejiang Province, Eastern China, during surveillance of AIVs in live poultry markets in 2016 and 2017. Phylogenetic analysis indicated that Zhejiang H10 strains received gene segments from H10, H3, and H7 viruses from birds in East Asia. Animal inoculation tests showed that these isolates have low pathogenicity in mice and can replicate in this species. Our findings suggest these H10 AIVs have the ability to adapt to chicken or other poultry, and highlight the need of long-term surveillance. PMID- 30302583 TI - Molecular characterization and analysis of conserved potyviral motifs in bean common mosaic virus (BCMV) for RNAi-mediated protection. AB - Australian bean common mosaic virus (BCMV) isolates were sequenced, and the sequences were compared to global BCMV and bean common mosaic necrosis virus (BCMNV) sequences and analysed for conserved potyviral motifs to generate in planta RNA-interference (RNAi) resistance. Thirty-nine out of 40 previously reported potyvirus motifs were conserved among all 77 BCMV/BCMNV sequences. Two RNAi target regions were selected for dsRNA construct design, covering 920 bp of the nuclease inclusion b (NIb) protein and 461 bp of the coat protein (CP). In silico prediction of the effectiveness of these constructs for broad-spectrum defence against the 77 BCMV and BCMNV sequences was done via analysis of putative 21-nucleotide (nt) and 22-nt small-interfering RNAs (siRNAs) generated from the target regions. The effectiveness of both constructs for siRNA generation and BCMV RNAi-mediated resistance was validated in Nicotiana benthamiana transient assays. PMID- 30302584 TI - Development and application of a simple recombinase polymerase amplification assay for rapid point-of-care detection of feline herpesvirus type 1. AB - Feline herpesvirus type 1 (FHV-1) is a highly contagious pathogen of domestic cats and other members of the family Felidae. Point-of-care diagnosis of persistent infection in cats is essential for control of its spread. A recombinase polymerase amplification (RPA) assay (RPA-LFD-FHV) combined with a lateral flow dipstrip (LFD) was developed that uses human body heat for incubation. Sensitivity was evaluated by testing a serial dilution of a control plasmid, and specificity was evaluated by testing related viruses. Swab samples from cats with suspected infection were tested by RPA-LFD-FHV, and the results were compared to those obtained by PCR to evaluate its clinical performance. The RPA-FLD-FHV assay was carried out successfully within 20 min, using body heat for incubation. The RPA-FLD-FHV had a detection limit of 103 copies of the FHV-1 gD gene, which was lower than that of PCR, which was 104 copies. The assay could detect templates of FHV-1 but not those of other feline and canine viruses. Viruses in boiled samples could be efficiently detected by the RPA-FLD-FHV. Thirty-one out of the 80 samples were positive by the RPA-FLD-FHV assay, whereas only 27 were positive by PCR. DNA sequencing confirmed that the four samples that were positive by RPA-FLD-FHV but negative by PCR were indeed positive. These results indicate that RPA-FLD-FHV is applicable for clinical use. The RPA-FLD-FHV assay is a simple, rapid, and reliable method for point-of-care diagnosis of FHV 1 infection.

AB - The aim of the present study was to evaluate the effects of treatment with different anthelmintic compounds on the productivity of naturally infected calves and the economic viability of these treatments within extensive breeding systems employing different nutritional strategies after weaning. For this purpose, 4 farms with 42-60 calves naturally infected with gastrointestinal nematodes were selected. The calves were distributed into 6 groups (7-10 animals each) per farm and treated with ivermectin 1%, ivermectin 3.15%, eprinomectin 5%, levamisole 7.5%, albendazole 15%, and control group (no treatment). These animals were evaluated over an experimental period of 150 days. Levamisole 7.5% presented the best capacity for the reduction of eggs per gram (EPG) of feces in all herds evaluated, followed by albendazole 15% and eprinomectin 5%. Parasite resistance to multiple drugs was found in all herds, especially those of Cooperia, Haemonchus, Oesophagostomum, and Trichostrongylus. For farm 1, differences in weight gain and EPG reduction percentages led to a difference of US$285.06 between the levamisole and ivermectin 3.15% groups. Similar findings were noted for the levamisole and ivermectin 1% groups of farm 3, with a difference of US$399.37 because of the final weight gain in these groups. For farms 2 and 4, the ivermectin 3.15% and control groups, respectively, were the most profitable; these unexpected results were possibly influenced by variables not measured during the experimental period. This study suggested that anthelmintic treatments should always precede an efficacy test, once they are demonstrated to be most profitable under adequate breeding conditions, to ensure adequate control of gastrointestinal nematode infection. PMID- 30302587 TI - Cercarial dermatitis: a systematic follow-up study of human cases with implications for diagnostics. AB - Cercarial dermatitis (CD) is an allergic skin disease that rises in consequence of infection by invasive stages (cercariae) of trematodes of the family Schistosomatidae. CD has been considered a re-emerging disease, human cases have been reported from all continents, and tourism-threatening outbreaks occur even in frequented recreational areas. Although the symptoms of CD are generally known, the data on immune response in human patients are sporadic and incomprehensive. In the present study, we attempted to correlate the symptoms, personal history, and time course of CD in human patients with differential cell counts, dynamics of selected cytokines, and dynamics and quality of antibody response. By a systematic follow-up, we obtained a uniquely complex dataset from ten persons accidentally and concurrently infected by the same parasite species in the same locality. The onset of CD was significantly faster, and the symptoms were heavier in participants with a history of CD if compared to naive ones, who, however, also developed some of the symptoms. The repeatedly infected persons had elevated proportion of eosinophils 1 week post exposure (p.e.) and a stronger specific IgG but not IgM response, whereas specific IgE response was not observed. Increased serum levels of IL-4 occurred 1 and 3 week(s) p.e. in all participants. There was high variability in individual immunoblot patterns of IgG response, and no antigen with a universal diagnostic potential was confirmed. The presented analyses suggested that a complex approach can improve the accuracy of the diagnosis of CD, but component data should be interpreted carefully. PMID- 30302588 TI - The prognostic value of tumour-stroma ratio in primary breast cancer with special attention to triple-negative tumours: a review. AB - PURPOSE: There is a strong need to improve the prognostication of breast cancer patients in order to prevent over- and undertreatment, especially when considering adjuvant chemotherapy. Tumour stroma characteristics might be valuable in predicting disease progression. METHODS: Studies regarding the prognostic value of tumour-stroma ratio (TSR) in breast cancer are evaluated. RESULTS: A high stromal content is related to a relatively poor prognosis. The most pronounced prognostic effect of this parameter seems to be observed in the triple-negative breast cancer (TNBC) subtype. CONCLUSIONS: TSR assessment might represent a simple, fast and reproducible prognostic factor at no extra costs, and could possibly be incorporated into routine pathological diagnostics. Despite these advantages, a robust clinical validation of this parameter has yet to be established in prospective studies. PMID- 30302589 TI - Deep-learning-based detection and segmentation of organs at risk in nasopharyngeal carcinoma computed tomographic images for radiotherapy planning. AB - OBJECTIVE: Accurate detection and segmentation of organs at risks (OARs) in CT image is the key step for efficient planning of radiation therapy for nasopharyngeal carcinoma (NPC) treatment. We develop a fully automated deep learning-based method (termed organs-at-risk detection and segmentation network (ODS net)) on CT images and investigate ODS net performance in automated detection and segmentation of OARs. METHODS: The ODS net consists of two convolutional neural networks (CNNs). The first CNN proposes organ bounding boxes along with their scores, and then a second CNN utilizes the proposed bounding boxes to predict segmentation masks for each organ. A total of 185 subjects were included in this study for statistical comparison. Sensitivity and specificity were performed to determine the performance of the detection and the Dice coefficient was used to quantitatively measure the overlap between automated segmentation results and manual segmentation. Paired samples t tests and analysis of variance were employed for statistical analysis. RESULTS: ODS net provides an accurate detection result with a sensitivity of 0.997 to 1 for most organs and a specificity of 0.983 to 0.999. Furthermore, segmentation results from ODS net correlated strongly with manual segmentation with a Dice coefficient of more than 0.85 in most organs. A significantly higher Dice coefficient for all organs together (p = 0.0003 < 0.01) was obtained in ODS net (0.861 +/- 0.07) than in fully convolutional neural network (FCN) (0.8 +/- 0.07). The Dice coefficients of each OAR did not differ significantly between different T-staging patients. CONCLUSION: The ODS net yielded accurate automated detection and segmentation of OARs in CT images and thereby may improve and facilitate radiotherapy planning for NPC. KEY POINTS: * A fully automated deep-learning method (ODS net) is developed to detect and segment OARs in clinical CT images. * This deep-learning based framework produces reliable detection and segmentation results and thus can be useful in delineating OARs in NPC radiotherapy planning. * This deep-learning based framework delineating a single image requires approximately 30 s, which is suitable for clinical workflows. PMID- 30302590 TI - An analysis of factors associated with increased fluoroscopy time or the need for complex techniques at IVC filter retrieval. AB - OBJECTIVES: To evaluate factors associated with increased fluoroscopy time or the need for complex techniques at IVC filter retrieval. METHODS: This is a single institution retrospective cohort study of 187 consecutive patients who underwent IVC filter retrieval. An analysis was performed on associations of patient factors with increased fluoroscopy time and/or the need for complex retrieval techniques. A complex retrieval was defined as one requiring more than standard sheath and snare technique. RESULTS: Access vein during filter placement was not associated with filter tilt at placement or removal (p = 0.61 and 0.48). Neither the direction of the hook nor its relationship to the tilt was associated with the need for complex retrieval or increased retrieval fluoroscopy time (p = 0.25, 0.23, p = 0.18, 0.23). Tilt angle at placement correlated with hook apposition at time of removal (p = 0.01). Hook apposition was associated with complex retrieval and increased fluoroscopy time (p < 0.01). Larger tilt angle at placement was not associated with complex retrieval (p = 0.22), but a larger angle at removal was (p < 0.01). Longer dwell time correlated with the need for complex retrieval (p = 0.02). Filter type, sex, and age were not associated with complex retrievals (p = 0.58, p = 0.90, p = 0.99). CONCLUSION: Contrary to previous hypotheses and studies, access vein for filter placement did not affect filter tilting, and direction of filter hook-tilt relationship did not affect retrieval fluoroscopy time or the need for complex retrieval techniques. Increased filter placement angle was associated with a larger angle at removal and hook-wall apposition, both of which were associated with complex retrievals. KEY POINTS: * Filter hook orientation did not correlate with retrieval complexity. * Filter insertion vein did not correlate with filter tilt. * Filter tilt and hook apposition to the caval wall at the time of retrieval correlated with retrieval procedure complexity. PMID- 30302591 TI - Preoperative evaluation of small bowel complications in Crohn's disease: comparison of diffusion-weighted and contrast-enhanced MR imaging. AB - PURPOSE: To compare the accuracy of MR enterography (MRE) using combined T2 weighted and contrast-enhanced (CE) sequences with that of combined T2- and diffusion-weighted (DW) sequences for the detection of complex enteric Crohn's disease (CD). MATERIALS: Thirty-eight patients who underwent surgery for CD complications and preoperative MRE from 2011 to 2016 were included. MRE examinations were blindly analyzed independently by one junior and one senior abdominal radiologist for the presence of fistula, stenosis and abscesses. During a first reading session, T2-weighted images (WI), steady-state sequences and DW MRE were reviewed (set 1). During a separate distant session, T2-WI, True-FISP and CE-MRE were reviewed (set 2). Performance of each reader was evaluated by comparison with the standard of reference established using intraoperative and pathological findings. RESULTS: Forty-eight fistulas, 43 stenoses and 11 abscesses were found. For the senior radiologist, sensitivity for the detection of fistula, stenosis and abscess ranged from 80% to 100% for set 1 and 88% to 100% for set 2 and specificity ranged from 56% to 70% for set 1 and 53% to 93% for set 2, with no significant difference between the sets (p = 0.342-0.429). For the junior radiologist, sensitivity ranged from 53% to 63% for set 1 and 64% to 88% for set 2 and specificity ranged from 0% to 25% for set 1 and 17% to 40% for set 2 (p = 0.001 and 0.007, respectively). CONCLUSION: For a senior radiologist, DW-MRE has similar sensitivity as CE-MRE for the detection of CD complications. For a junior radiologist, CE-MRE yields the best results compared with DW-MRE. KEY POINTS: * For experienced readers, DWI has similar diagnostic capability as contrast-enhanced MR imaging for the diagnosis of Crohn's disease complications. * For senior radiologists, gadolinium chelate injection could be waived for the diagnosis of Crohn's disease complications. * The interpretation of DWI for Crohn's disease complications requires some experience. PMID- 30302592 TI - Lower urinary tract dysfunction in chronic Chagas disease: clinical and urodynamic presentation. AB - PURPOSE: To describe and give an estimation of the prevalence of urinary disorders in chronic Chagas disease, since most clinical research has been centered on the description of the cardiac and digestive forms. METHODS: To explore this topic, a cross-sectional study was conducted in 137 Bolivian adults of both sexes suffering from symptomatic chronic Chagas disease. All patients presenting confirmed chagasic cardiomyopathy, megacolon or both underwent a urologic symptom questionnaire, uroflowmetry, urinary tract ultrasonography and a creatinine assay. When urinary abnormality was detected, a complete urodynamic study was proposed including cystometry, pressure-flow studies and urethral pressure profile. RESULTS: Out of all study patients, 35 (26%) had a Chagas cardiomyopathy, 81 (59%) a megacolon, and 21 (15%) a megacolon associated with cardiomyopathy. In all, 63% presented urinary disorders defined by IPSS > 7 and/or ICIQ SF > 1. Among them, 62% were incontinent, mainly by bladder overactivity, and 45% presented grade 2 or 3 renal insufficiency. Of 49 patients, the urodynamic study identified 34 patients with detrusor overactivity (69%), mostly in those with Chagas megacolon. Median bladder functional capacity, urethral closure pressure and bladder compliance had normal values. Moreover, 36% of these patients presented moderate hypocontractility, without significant post void residual. CONCLUSIONS: This study evidenced lower urinary tract dysfunction in a majority of chronic chagasic patients; those presenting megacolon were more likely to suffer from urinary incontinence. These results strongly suggest including routine urological clinical investigation in chronic Chagas patients, as urinary incontinence due to overactive bladder is frequently observed in this population. PMID- 30302593 TI - Supracostal access tubeless percutaneous nephrolithotomy: minimizing complications. AB - INTRODUCTION AND OBJECTIVE: Supracostal access in percutaneous nephrolithotomy (PCNL) may be avoided due to concern for thoracic complications. The objective of the study is to report the safety and efficacy of supracostal access utilizing a tubeless (stent only) PCNL technique. PATIENTS AND METHODS: Retrospective review of perioperative outcomes of 70 patients (76 renal units) who underwent a supracostal tubeless PCNL. No nephrostomy tubes were left. All patients had a 7F ureteral stent and Foley catheter placed. The nephrostomy sheath was removed with the patient held in end-expiration, and the incision closed. RESULTS: Median (IQR) age was 62 (48.3-67) years. Median stone size was 20 * 21 mm, and 14 (18%) patients had complete staghorn stones. The upper calyx was the site of access in 52 (68.4%) cases. Access was above the 12th and 11th rib in 63 (83%) and 12 (16%) cases, respectively. Median (IQR) length of stay was 30 (28-32) hours. Fifty (68.5%) patients had no residual fragments (< 2 mm) on postoperative imaging. Eight (11%) patients underwent an ancillary procedure (7 URS and 1 ESWL), with an additional seven patients becoming stone free after this procedure (78%). Thoracic complications occurred in two (2.6%) patients: one small pneumothorax, and one pleural effusion, both managed conservatively. Other complications occurred in nine patients (11.8%): bleeding requiring transfusion (1), fever (4), urinary retention (2), and syncope (2). CONCLUSION: Compared to historical controls, our approach to upper tract PCNL utilizing a nephrostomy tube-free approach resulted in an overall low thoracic complication rate and facilitated hospital discharge. PMID- 30302594 TI - First ovarian response to gonadotrophin stimulation in rats exposed to neonatal androgen excess. AB - This study analyzes the effects of neonatal androgenization on follicular growth and first ovulation in response to gonadotrophins, using a model of exogenous stimulation or the use of subcutaneous ovary grafts in castrated animals to replace the hypothalamus-pituitary signal. Neonatal rats (days 1-5) were treated with testosterone, dihydrotestosterone or vehicle. At juvenile period, rats were stimulated with PMSG, hCG (alone or combined) or used as ovarian donors to be grafted on castrated adult female rats. Ovulation and ovarian histology were analyzed in both groups. Animals treated with vehicle or dihydrotestosterone stimulated with gonadotrophins (pharmacological or by using an ovary graft) ovulated, showing a normal histological morphology whereas rats exposed to testosterone and injected with the same doses of gonadotrophins did not it. In this group, ovulation was reached using a higher dose of hCG. Ovaries in the testosterone group were characterized by the presence of follicles with atretic appearance and a larger size than those observed in control or dihydrotestosterone groups. A similar appearance was observed in testosterone ovary grafts although luteinization and some corpora lutea were also identified. Our findings suggest that neonatal exposure to aromatizable androgens induces a more drastic signalling on the ovarian tissue that those driven by non aromatizable androgens in response to gonadotrophins. PMID- 30302595 TI - Age of Initial Identification of Autism Spectrum Disorder in a Diverse Urban Sample. AB - This paper examines age of autism spectrum disorder (ASD) identification and related factors in a diverse urban sample, focusing on ASD identification in the East African Somali community. The overall average age of initial ASD identification was 4.8 years. Somali children received an initial clinical diagnosis of Autistic Disorder later than White children, and Somali children diagnosed with ASD born outside of Minnesota (MN) received their first comprehensive evaluation later than Somali children diagnosed with ASD born in MN. Most children had noted developmental concerns before age 3, with no significant racial or ethnic differences in those concerns. The current study contributes to a limited number of studies on early ASD identification in culturally and linguistically diverse populations. PMID- 30302596 TI - Melanocyte activation and skin barrier disruption induced in melasma patients after 1064 nm Nd:YAG laser treatment. AB - Melasma is a frequently acquired hyperpigmentary skin disorder, for which several therapies are available. Among them, 1064 nm QS Nd:YAG laser therapy is an effective method, but the recurrence rate of laser treatment is still high. The aim of the present study was to elucidate the mechanism of the high relapse rate of melasma after 1064 nm Nd:YAG laser treatment. Twenty-five female melasma patients were treated with 1064 nm Nd:YAG laser for 10 times. The lesional skin and non-lesional skin were evaluated by means of a reflectance confocal laser scanning microscope before and after laser treatment. Melanin content and transepidermal water loss (TEWL) were measured by an MPA9 skin multifunction tester accordingly. The melanin index value was significantly decreased in the lesional skin after laser treatment, while the non-lesional skin had no difference. The dendritic cells were observed at the level of the dermal epidermal junction (DEJ) in the lesions of 8 patients before laser treatment, while after laser treatment, the dendritic cells were observed in all 25 subjects. Moreover, there was significant difference between the TEWL value of the lesions before and after laser treatment. Furthermore, the TEWL value was higher in lesions of the 8 subjects which had dendritic cells compared with other 17 subjects which had no dendritic cells, no matter before or after laser treatment. The relapse patients of melasma had higher TEWL value compared with the non-relapse patients. Melanocyte activation and skin barrier disruption may be related to the high relapse rate of melasma after laser treatment.

PMID- 30302598 TI - Spatial correlations between MRI-derived wall shear stress and vessel wall thickness in the carotid bifurcation. AB - BACKGROUND: To explore the possibility of creating three-dimensional (3D) estimation models for patient-specific wall thickness (WT) maps using patient specific and cohort-averaged WT, wall shear stress (WSS), and vessel diameter maps in asymptomatic atherosclerotic carotid bifurcations. METHODS: Twenty subjects (aged 75 +/- 6 years [mean +/- standard deviation], eight women) underwent a 1.5-T MRI examination. Non-gated 3D phase-contrast gradient-echo images and proton density-weighted echo-planar images were retrospectively assessed for WSS, diameter estimation, and WT measurements. Spearman's rho and scatter plots were used to determine correlations between individual WT, WSS, and diameter maps. A bootstrapping technique was used to determine correlations between 3D cohort-averaged WT, WSS, and diameter maps. Linear regression between the cohort-averaged WT, WSS, and diameter maps was used to predict individual 3D WT. RESULTS: Spearman's rho averaged over the subjects was - 0.24 +/- 0.18 (p < 0.001) and 0.07 +/- 0.28 (p = 0.413) for WT versus WSS and for WT versus diameter relations, respectively. Cohort-averaged rho, averaged over 1000 bootstraps, was 0.56 (95% confidence interval [- 0.74,- 0.38]) for WT versus WSS and 0.23 (95% confidence interval [- 0.06, 0.52]) for WT versus diameter. Scatter plots did not reveal relationships between individual WT and WSS or between WT and diameter data. Linear relationships between these parameters became apparent after averaging over the cohort. Spearman's rho between the original and predicted WT maps was 0.21 +/- 0.22 (p < 0.001). CONCLUSIONS: With a combination of bootstrapping and cohort-averaging methods, 3D WT maps can be predicted from the individual 3D WSS and diameter maps. The methodology may help to elucidate pathological processes involving WSS in carotid atherosclerosis. PMID- 30302599 TI - Phase I/II study of everolimus combined with mFOLFOX-6 and bevacizumab for first line treatment of metastatic colorectal cancer. AB - Background This phase I/II trial evaluated toxicity and antitumor activity of everolimus plus mFOLFOX6 + bevacizumab for first-line treatment of metastatic colorectal cancer (mCRC). Methods A phase I, modified 3 + 3 Fibonacci schema determined the maximum tolerated dose (MTD) of everolimus, followed by phase II dose expansion. The phase II primary objective was progression-free survival at 6 months (PFS-6 m). Results The everolimus MTD was 10 mg daily with mFOLFOX6 + bevacizumab based on safety from phase I (n = 22). Twenty-five patients were treated in the phase II at 10 mg everolimus daily. Frequent grade 3-4 adverse events were neutropenia (64%), leukopenia (28%) and hypokalemia (26%). Grade 2 stomatitis was observed in 62% of patients. Two dose-limiting toxicities were observed with one attributed to everolimus 10 mg daily (grade 3 diarrhea, hypokalemia, and anorexia) and grade 3 coronary vasospasm attributed to fluorouracil. The objective response rate was 53% and was higher (86%) in those with PTEN deficiency. PFS-6 m was 96% (95% CI 89-99.9%) at the MTD (n = 35). The everolimus recommended phase II dose of this regimen is 7.5 mg daily due to frequent stomatitis and dose reductions. Conclusions Everolimus plus mFOLFOX-6 + bevacizumab is tolerable and demonstrated preliminary efficacy for first-line mCRC. Further studies are warranted in PTEN deficiency.

PMID- 30302601 TI - DNA binding, cleavage and cytotoxicity studies of three mononuclear Cu(II) chloro complexes containing N-S donor Schiff base ligands. AB - We report the biological activity of three Cu(II) complexes [Cu(pabt)Cl] (1), [Cu(pma)Cl] (2), and [Cu(pdta)Cl]Cl (3) (pabt = N-(2-mercaptophenyl)-2' pyridylmethylenimine, pma = N-(2-pyridylmethyl)-2-mercaptoaniline, pdta = 2,2' di(pyridyl-2-methyleneimine)diphenyl disulfide). 1-3 display four-line EPR multiplet in solution at RT suggesting that these are mononuclear. DNA-binding studies using spectrophotometric titration of these complexes with calf thymus DNA showed binding through intercalation mode which was found to be consistent with the observation of increased viscosity of DNA and quenching of fluorescence of ethidium bromide bound DNA in the presence of these complexes. All three complexes were found to be efficient in bringing about oxidative and hydrolytic cleavage of DNA. The proposed mechanism of hydrolytic DNA cleavage has been discussed. MTT assay showed remarkable cytotoxicity on cervical cancer HeLa cell line and the IC50 values were 1.27, 4.13, and 3.92 MUM for 1, 2 and 3, respectively, as compared to the IC50 value (13 MUM) reported for cisplatin in HeLa cells. AO/PI and Annexin-V/PI assay suggest the induction of cell death primarily via apoptotic pathway. Nuclear staining using DAPI was used to assess changes in nuclear morphology during apoptotic cell death. The role of reactive oxygen species (ROS) for induction of apoptotic cell death was studied using H2DCF-DA assay and the result suggests that the generation of ROS by the complexes may be a possible cause for their antiproliferative activity. TUNEL assay showed DNA fragmentation in apoptotic cells. Cell cycle analysis using flow cytometry showed significant increase in the G2/M phase in HeLa cells by the compounds 1-3. Mononuclear Cu(II) complexes display remarkable cytotoxicity against cervical cancer HeLa cell line. The generation of ROS by the complexes may be a cause of their antiproliferative activity. Fluorescent images from DAPI staining assay revealed that the cells undergoing apoptosis displayed typical features like cell shrinkage, membrane blebbing, chromatin condensation and nuclear fragmentation. TUNEL assay showed DNA fragmentation in apoptotic cells. PMID- 30302602 TI - Comparison of Erich arch bar versus embrasure wires for intraoperative intermaxillary fixation in mandibular fractures. AB - PURPOSE: Intermaxillary fixation (IMF) is a fundamental principle in the management of mandibular fractures but with recent advent of open reduction and internal fixation (ORIF), use of IMF is almost limited intraoperatively. Therefore, we compared the efficacy of Erich arch bar versus embrasure wires for intraoperative IMF in mandibular fractures. METHOD: This prospective study was comprised of 50 patients with mandibular fractures who required ORIF with intraoperative IMF. Patients were categorized into two groups of 25 patients each: Erich arch bar technique was used for group A and embrasure wire technique for group B. Parameters were time taken for IMF, needle stick injury, occlusal stability, iatrogenic complications, and periodontal status of patients. STATISTICAL ANALYSIS: Chi-squared test and unpaired t test analyses was run on IBM SPSS 21.0 version (2015) software. RESULT: Mean time for placing embrasure wire (3.48 min) was significantly less than that for Erich arch bar (48.08 min). Needle stick injury rates to the operator as well as the assistants were significantly less when using the embrasure wire than the Erich arch bar. The Erich arch bar had significantly superior postoperative occlusion stability. Iatrogenic injury was more common when placing the Erich arch bar than the embrasure wire. Postoperative oral hygiene status was good in patients that received the embrasure wire. CONCLUSION: Embrasure wire technique is a quick, easy, and reliable technique for minimally or moderately displaced fractured mandible and had better clinical outcomes than did patients that underwent the Erich arch bar technique.

AB - PURPOSE: Cigarette smoking among cancer survivors increases the risk of recurrence and secondary cancers. We sought to investigate smoking cessation following diagnosis of cancer compared to those not diagnosed with cancer. We also investigated cessation following diagnosis of a smoking-related and non smoking-related cancer separately. METHODS: We conducted a matched cohort study within the Health Professionals Follow-Up Study (HPFS). We identified 566 men diagnosed with cancer who were current cigarette smokers at the time of diagnosis between 1986 and 2010 (exposed). Men diagnosed with cancer were age-matched 1:4 to men without a diagnosis of cancer who were also current cigarette smokers (unexposed). Multivariable conditional logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (CI) to evaluate the association between a cancer diagnosis and smoking cessation within 2 and 4 years post diagnosis adjusted for potential confounders, overall and for smoking related and non-smoking-related cancers. RESULTS: Of the men with cancer, 38% quit within 2 years and 42% within 4 years of diagnosis. Men diagnosed with cancer were more likely to quit smoking within 2 (OR = 2.5, 95% CI: 2.0-3.0) and 4 years (OR = 1.6, 95% CI: 1.3-2.0) post diagnosis, compared to matched men without cancer. The association was similar for smoking-related (OR = 3.4, 95%: 1.6-7.2) and non-smoking-related cancers (OR = 3.8, 95%: 2.8-5.2). CONCLUSIONS: Men diagnosed with cancer were more likely to quit smoking compared to men not diagnosed with cancer. A cancer diagnosis may be a "teachable moment" in which strategies to promote smoking cessation for individuals diagnosed with smoking related and non-smoking-related cancers should be investigated. IMPLICATIONS FOR CANCER SURVIVORS: There is a continued need for the widespread implementation of cessation interventions for cancer survivors.

AB - OBJECTIVES: Bond strength to enamel and dentin depends on the bonding approach or condition. This study investigated the effects of the boundary conditions, in terms of the bonding substrate and the bonding condition, on the shrinkage vectors of a flowable composite. MATERIALS AND METHODS: An experimental cylindrical cavity (diameter = 6 mm, depth = 3 mm) consisting of the enamel floor and the surrounding dentin cavity walls was prepared for the "enamel-floor" group. Cylindrical cavities of the same dimensions were prepared with access from the occlusal enamel into dentin and served as controls. Each cavity model group was divided and bonded with two bonding conditions (n = 9): a self-etch (Adper Easy Bond, 3M ESPE) and a total-etch approach (OptiBond FL, Kerr). The composite (Tetric EvoFlow, Ivoclar Vivadent) was mixed with glass beads, applied to the cavity, scanned twice by micro-CT (uncured and cured states). The scans were evaluated by rigid registration, sphere segmentation, and registration for computing shrinkage vectors. RESULTS: The free surface of all restorations moved downward. The shrinkage vectors in the experimental cavity model pointed downward towards the enamel cavity floor, and the net axial movement was downward. In the control group, shrinkage vectors additionally moved upward, away from the cavity floor. The effect of the bonding substrate and the bonding condition was investigated for the shrinkage vectors and the axial movement (univariate ANOVA). CONCLUSION: The bonding substrate, enamel, influenced the shrinkage vectors' direction, while the bonding condition caused only variations in the magnitude. CLINICAL RELEVANCE: Bonding to enamel influences shrinkage vectors' direction, while the bonding condition plays only a minor role. Graphical abstract ?.

AB - OBJECTIVE: The aim of this study was to assess the effectiveness of a hydroxyapatite/collagen composite material (HAp/Col) for preservation of alveolar bone after tooth extraction. MATERIALS AND METHODS: HAp/Col was applied to the alveolus bone ridge preservation after tooth extraction, because of subsequent dental implant placement in 35 regions of 24 patients (mean age, 59.3 years; range, 25-81 years). Cone beam computed tomography was used to assess changes in alveolar bone at the extraction site before and at 3 months (mean, 13.7 weeks; range, 10-17 weeks) after tooth extraction. Changes in height and width of the alveolar bone were measured to evaluate bone reduction after surgery. Bone biopsy was performed at 11 regions of dental implant placement to observe bone regeneration and remaining material in the extraction socket. RESULTS: The alveolar bone height was decreased by 0.00 +/- 2.44 mm at the buccal side and 0.35 +/- 1.73 mm at the lingual side, while the width was decreased by 1.02 +/- 1.64 mm at 3 months after surgery. The middle of the socket floor was elevated by 5.71 +/- 3.45 mm at 3 months after surgery. Bone biopsy specimens revealed no remaining implanted material, and approximately 49.79 +/- 14.41% of the specimens were occupied by bone tissue. CONCLUSIONS: According to the result of this study, HAp/Col is a reliable material to presearve alveolar bone after tooth extraction. CLINICAL RELEVANCE: HAp/Col contributes dental implant treatment due to maintain the alveolar bone after tooth extraction. PMID- 30302607 TI - Comparative evaluation of autofluorescence imaging and histopathological investigation for oral potentially malignant disorders in Taiwan. AB - OBJECTIVES: Autofluorescence imaging is gaining popularity as an adjunctive test for oral potentially malignant disorders (OPMD). This study evaluated the efficacy of autofluorescence imaging based on the current standard oral mucosal disorder checklist in Taiwan. MATERIALS AND METHODS: In total, 126 patients suspected to have mucosal disorders at the Division of Oral and Maxillofacial Surgery, Tri-Service General Hospital, Taipei, Taiwan, were enrolled. Following a conventional oral examination by using the oral mucosal disorder checklist and an autofluorescence imaging examination, all participants underwent histopathological examination to access epithelial dysplasia. RESULTS: Among 126 patients, 68 patients were diagnosis as having an OPMD and 63 having epithelial dysplasia. Autofluorescence imaging exhibited a sensitivity, specificity, positivity predictive value (PPV), negative predictive value (NPV), and accuracy of 77.94%, 35.42%, 63.10%, 53.13%, and 60.34%, respectively, for OPMD and of 88.89%, 43.86%, 63.64%, 78.13%, and 67.50%, respectively, for epithelial dysplasia. After the exclusion of 48 non-OPMD cases according to the checklist, the sensitivity, specificity, PPV, NPV, and accuracy of autofluorescence imaging became 87.50%, 72.73%, 94.23%, 53.33%, and 85.07%, respectively, for epithelial dysplasia. CONCLUSION: The efficacy of epithelial dysplasia identification and OPMD risk assessment can be increased after the exclusion of the non-OPMD cases through autofluorescence imaging. CLINICAL RELEVANCE: Autofluorescence imaging is a useful adjunct that can assist specialists in assessing OPMD patients prone to dysplasia without compromising patient care. PMID- 30302608 TI - Yes-associated protein (YAP) molecule expression in odontogenic epithelium of ameloblastoma. AB - OBJECTIVES: YAP (Yes-associated protein molecule) augments multiple processes known to be important for tumor progression and metastasis. Hence, the application of YAP as a targeted therapy for several malignancies has been documented in the literature. Ameloblastoma being a locally invasive odontogenic lesion causes tissue destruction and presents with a great chance of recurrence. Based on these qualities, we hypothesized that YAP could exhibit increased expression in the odontogenic epithelium of ameloblastoma. Therefore, the objective of the present study was to evaluate the immunohistochemical expression of YAP in ameloblastoma and compare the immunoreactivity of YAP in ameloblastoma and dental follicle. MATERIALS AND METHODS: Twenty-four paraffin-embedded tissue blocks of ameloblastoma and dental follicle each were retrieved from the departmental archives. Immunohistochemical (IHC) staining was performed employing YAP antibody on 5-MUm thick sections. The expression of YAP was reviewed on the peripheral lining of ameloblast-like cells and centrally placed stellate reticulum-like cells and was further graded as negative, weak, or strong. For data analysis, Chi-square test and Fisher's exact test were applied. RESULTS: In ameloblastoma, peripheral/basal cells exhibited strong expression for YAP in 12/24 cases and weak expression in the other 12 cases. Whereas, 20 cases of dental follicle presented negative expression and only four cases exhibited weak expression (p < 0.001). On statistical analysis, the differences in expression of YAP in stellate cells of ameloblastoma and dental follicle were found to be significant (p < 0.001). CONCLUSION: YAP expression was strongly seen in ameloblastoma as compared to the epithelial islands of dental follicle. The neoplastic nature of ameloblastoma could be attributed to YAP molecule and it may play a possible role in tumor invasiveness. CLINICAL RELEVANCE: Positive YAP expression in ameloblastoma and negative expression in the odontogenic epithelial islands of dental follicle insinuate that YAP could be responsible for the aggressiveness and local tissue invasion commonly encountered with ameloblastoma. PMID- 30302609 TI - Presentation of gaps around endodontic access cavity restoration by phase contrast-enhanced micro-CT. AB - OBJECTIVE: To evaluate the feasibility of synchrotron-based phase-contrast (PC) MUCT for visualization of the gaps and differentiation between the gaps, restorative, and endodontic materials at the tooth-restoration interface. MATERIALS AND METHODS: Standardized access cavities were prepared in human maxillary molars and subjected to materials, simulating endodontic treatment: (1) saline irrigation; (2) NaOCl and 17% EDTA irrigation; (3) same as group 2, followed by application of Ca(OH)2; and (4) same as group 2, followed by application of root canal sealer. The access cavities were cleaned and restored using an etch-and-rinse adhesive and a composite material in multilayering technique. The samples were thermocycled (1000 cycles, 5-55 degrees C). Synchrotron-based MUCT imaging was performed obtaining absorption and PC MUCT images before and after the immersion of the samples into 50% AgNO3. PC MUCT images were compared to absorption MUCT and conventional optical microscopy images. RESULTS: PC MUCT of unstained samples enabled the best visualization of gaps and differentiation of restorative and endodontic materials, contaminating the cavity surface. PC MUCT revealed that AgNO3 staining leads to an overestimation of gap size due to anterograde and retrograde AgNO3 infiltration into dentinal tubules and underestimation of large gaps due to lack of AgNO3 penetration. CONCLUSION: Synchrotron PC MUCT imaging enables better visualization of gap and differentiation of materials at the tooth-restoration interface. MUCT imaging with AgNO3 staining has shown certain over- and underestimations. Future research should be aimed at incorporating PC MUCT imaging of unstained samples for the validation of results obtained with other methods. CLINICAL SIGNIFICANCE: Contamination of cavity walls with an endodontic sealer or Ca(OH)2 leads to increased gap formation at the tooth-restoration interface. PMID- 30302610 TI - Comparing the outcomes of gold-standard dental examinations with photographic screening by mid-level dental providers. AB - OBJECTIVES: To determine the detectability of the intra-oral photographic method in comparison to the baseline, comprehensive dental examination (CDE), in children when performed by different levels of dental practitioners. MATERIALS AND METHODS: As part of a quality assurance program, intra-oral photographs were obtained from 77 patients (2-18 years) as part of a CDE before undertaking dental treatment under general anaesthesia. A DSLR camera was utilised to acquire images which were subsequently uploaded to a cloud-based server. The baseline for each participant was established during the CDE, utilising both visual and radiographic examination, which was then compared to the assessment made by a mid level dental practitioners (MLDP). The evaluation was based on utilising an odontogram where the teeth were charted either as decayed or filled. RESULTS: Specificity (95%) was higher than sensitivity (61.5%) when comparing the photographic assessment with the benchmark CDE assessment. The inter-rater reliability between the two methods of assessment was substantial, with a kappa score of 0.62. The photographic assessment method underestimated the decayed and filled teeth, as observed by the caries experience (dft/DFT scores) (CDE = 7.01 vs. photographic assessment = 5.22). There were lower levels of diagnostic detection in the posterior teeth as compared to the anterior teeth assessments. CONCLUSIONS: Although the CDE is still considered to be the gold-standard, this study found that the photographic caries assessment by MLDP produced an acceptable diagnostic level of detection particularly for the anterior teeth. CLINICAL RELEVANCE: The photographic method could offer a potential cost-saving and user-friendly screening. PMID- 30302611 TI - Bone repair in craniofacial defects treated with different doses of alendronate: a histological, histomorphometric, and immunohistochemical study. AB - OBJECTIVE: The objective of the study is to evaluate bone repair in rats treated with different alendronate doses. MATHERIALS AND METHODS: Sixty female rats ovariectomized were randomly divided in three groups: group C (control group), group A1 (ALN/1 mg/kg), and A2 (ALN/ 3 mg/kg). Each animal received subcutaneous applications of sodium alendronate at a dose correspondent to group A1 or A2 three times a week, while the control group received 0.9% saline solution. After 4 weeks of application, a critical defect was created in the calvaria of animals of all groups. The defect was filled by particulate autogenous bone. The applications were maintained until euthanasia, which occurred 15 and 60 days after the surgical procedure. The pieces were sent for histological, histomorphometric and immunohistochemical analysis. The data were submitted to statistical analysis with significance level of 0.05. RESULTS: The descriptive histological analysis demonstrated an increase in bone neoformation in both groups treated with alendronate when compared to the control group. The histomorphometric analysis showed an increase in the amount of neoformed bone in A1 and A2 groups when compared to group C, both at 15 days (p = 0.0002) and at 60 days (p = 0.001). In the immunohistochemical analysis, it was possible to observe a difference in immunolabeling just for Mmp2 at the time of 60 days in A1 (p = 0.001) and A2 (p = 0.023) when compared to the control group. CONCLUSION: Systemic delivery of alendronate, regardless of the dose, increased the amount of bone neoformation. CLINICAL RELEVANCE: Prescription of sodium alendronate at 1 mg/kg for improvement of bone neoformation in bone graft procedures. PMID- 30302612 TI - Effect of sucralfate against hydrochloric acid-induced dental erosion. AB - OBJECTIVE: Devising effective measures for the prevention of hydrochloric acid (HCl)-induced erosion is of great significance. This is even more important in dentine, in which products have limited diffusion. Therefore, agents that can bind to proteins forming an acid-resistant gel-like coat, such as sucralfate, may stand out as a promising alternative. This study investigated the protective effect of sucralfate suspensions against HCl-induced dental erosion. MATERIALS AND METHODS: In the first experiment, hydroxyapatite (HAp) crystals were pre treated with a commercial sucralfate suspension (CoSS, pH 5.9), a stannous containing sodium fluoride solution (NaF/SnCl2 pH 4.5), two prepared sucralfate suspensions (PrSS, pH 5.9 and 4.5), or deionized water (DI, control). HAp dissolution was measured using a pH-stat system. In a subsequent experiment, embedded/polished enamel and root dentine slabs were allocated into five groups to be treated with one of the tested substances prior to and during erosion remineralization cycles (HCl-2 min + artificial saliva 60 min, two times per day, 5 days). Surface loss was assessed profilometrically. Data were analyzed by ANOVA and Tukey's tests. RESULTS: HAp dissolution was as follows: NaF/SnCl2 < CoSS < PrSS/pH 4.5, while PrSS/pH 5.9 = DI and both did not differ from CoSS and PrSS/pH 4.5. In enamel, surface loss did not differ between CoSS and PrSS/pH 4.5, with both having lower surface loss than PrSS/pH 5.9 and DI and NaF/SnCl2 differing only from DI. In root dentine, surface loss was as follows: CoSS < PrSS/pH 5.9 < (NaF/SnCl2 = DI), while PrSS/pH 4.5 = CoSS = PrSS/pH 5.9. CONCLUSION: Sucralfate suspension provided anti-erosive protection to HCl-induced erosion. CLINICAL RELEVANCE: Sucralfate may protect teeth against erosion caused by gastric acid. PMID- 30302614 TI - Assembly and Trafficking of Homomeric and Heteromeric Kainate Receptors with Impaired Ligand Binding Sites. AB - Kainate receptors (KARs) are a subfamily of ionotropic glutamate receptors (iGluRs) mediating excitatory synaptic transmission. Cell surface expressed KARs modulate the excitability of neuronal networks. The transfer of iGluRs from the endoplasmic reticulum (ER) to the cell surface requires occupation of the agonist binding sites. Here we used molecular modelling to produce a range of ligand binding domain (LBD) point mutants of GluK1-3 KAR subunits with and without altered agonist efficacy to further investigate the role of glutamate binding in surface trafficking and activation of homomeric and heteromeric KARs using endoglycosidase digestion, cell surface biotinylation and imaging of changes in intracellular Ca2+ concentration [Ca2+]i. Mutations of conserved amino acid residues in the LBD that disrupt agonist binding to GluK1-3 (GluK1-T675V, GluK2 A487L, GluK2-T659V and GluK3-T661V) reduced both the total expression levels and cell surface delivery of all of these mutant subunits compared to the corresponding wild type in transiently transfected human embryonic kidney 293 (HEK293) cells. In contrast, the exchange of non-conserved residues in the LBD that convert antagonist selectivity of GluK1-3 (GluK1-T503A, GluK2-A487T, GluK3 T489A, GluK1-N705S/S706N, GluK2-S689N/N690S, GluK3-N691S) did not alter the biosynthesis and trafficking of subunit proteins. Co-assembly of mutant GluK2 with an impaired LBD and wild type GluK5 subunits enables the cell surface expression of both subunits. However, [Ca2+]i imaging indicates that the occupancy of both GluK2 and GluK5 LBDs is required for the full activation of GluK2/GluK5 heteromeric KAR channels. PMID- 30302613 TI - Trans-cinnamaldehyde Modulates Hippocampal Nrf2 Factor and Inhibits Amyloid Beta Aggregation in LPS-Induced Neuroinflammation Mouse Model. AB - Trans-cinnamaldehyde (CNM) has recently drawn attention due to its potent anti inflammatory and antioxidant properties. The current study explored the memory enhancing effects of CNM against lipopolysaccharide (LPS)-induced neuroinflammation in mice. CNM and curcumin (a reference antioxidant) were administered at a dose of 50 mg/kg i.p. 3 h after a single LPS injection (0.8 mg/kg, i.p.) and continued daily for 7 days. Our results displayed that CNM and curcumin significantly ameliorated the LPS-induced impairment of learning and memory, neuroinflammation, oxidative stress and neuronal apoptosis. Memory functions and locomotor activity were assessed by Morris water maze, object recognition test and open field test. Both CNM and curcumin activated the nuclear factor erythroid 2 related factor 2 (Nrf2) and restored levels of downstream antioxidant enzymes superoxide dismutase and glutathione-S-transferase (GST) in the hippocampus. They also attenuated LPS-induced increase in hippocampal contents of interleukin-1beta (IL-1beta), malondialdehyde and caspase-3. Immunohistochemistry results showed that both CNM and curcumin reduced Abeta1-42 protein accumulation in brain of mice. Remarkably CNM's effect on IL-1beta was less pronounced than curcumin; however it showed higher GST activity and more potent anti-apoptotic and anti-amylodogenic effect. We conclude that, CNM produces its memory enhancing effects through modulation of Nrf2 antioxidant defense in hippocampus, inhibition of neuroinflammation, apoptosis and amyloid protein burden. PMID- 30302615 TI - Field grown transgenic Pm3e wheat lines show powdery mildew resistance and no fitness costs associated with high transgene expression. AB - Pm3 from wheat encodes a nucleotide-binding leucine-rich repeat type of receptor and confers resistance to powdery mildew caused by the fungal pathogen Blumeria graminis f.sp. tritici (Bgt). Each of the 17 functional Pm3 alleles identified so far confers resistance to a distinct spectrum of Bgt isolates. Variant Pm3e has been found in wheat donor line W150 and differs only by two amino acids from the non-functional variant Pm3CS. In order to evaluate the capability of Pm3e to provide powdery mildew field resistance, we generated transgenic Pm3e lines by biolistic transformation of the powdery mildew susceptible spring wheat cultivar Bobwhite. Field trials conducted during four field seasons in Switzerland showed significant and strong powdery mildew resistance of the Pm3e transgenic lines, whereas the corresponding biological sister lines, not containing the transgene, were severely powdery mildew infected. Thus Pm3e alone is responsible for the strong resistance phenotype. The field grown transgenic lines showed high transgene expression and Pm3e protein accumulation with no fitness costs on plant development and yield associated with Pm3e abundance. Line E#1 as well as sister line E#1 showed delayed flowering due to somaclonal variation. The study shows the capability of Pm3e in providing strong powdery mildew field resistance, making its use in wheat breeding programs very promising. PMID- 30302616 TI - Chick embryonic cells as a source for generating in vitro model of muscle cell dystrophy. AB - Chick embryonic cells can be used to develop an easy and economical in vitro model for conducting studies on the disease muscle dystrophy (MD). For this, the limb myoblasts from 11th day chick embryo were isolated and cultured. To this muscle cell culture, anti-dystroglycan antibody (IIH6) was added so as to target the alpha-dystroglycan and disrupt the connection between the cytoskeletal proteins and the extracellular matrix (which is a characteristic feature of MD). Cells were allowed to differentiate further and the morphometrics and mRNA expression were studied. The IIH6-treated muscle cells displayed changes in morphometry, contractibility, and also atrophy was observed when compared to the control cultures. Concomitant gene expression studies showed an upregulation in TGF-beta expression, while the muscle sculpture genes MYOD1, MYF5, LAMA2 and MYOG were downregulated resembling the MD in vivo. This simple and cost-effective method can be useful in studies to further understand the disease mechanism and also in conducting initial studies on effect of novel pharmacological agents. PMID- 30302617 TI - Role of PI3K-Akt and MAPK Signaling in Uranyl Nitrate-Induced Nephrotoxicity. AB - Uranium is a heavy metal of considerable environmental and occupational concern. It is well-known that the kidney is the major target organ of uranium exposure. Elucidating the mechanistic basis of uranium interactions is essential for monitoring the health risk. In the present study, we investigated the cellular mechanisms involved in uranyl nitrate-induced nephrotoxicity. Male Swiss albino mice were administrated with a single intraperitoneal dose of 2 and 4 mg/kg of uranyl nitrate at different time points 1, 3, 5, 7, 14, and 28 days. Uranyl nitrate intoxication-induced apoptosis in the kidney tissue was observed by TUNEL assay. To assess the proliferation, immunohistochemistry was performed using Ki67 proliferative marker followed by western blotting to confirm the involvement of key signaling molecules. The number of TUNEL positive nuclei peaked at third day after uranyl nitrate insult. The increased expression of proliferation marker Ki67 suggests the enhanced DNA repair process prominently at seventh day. Uranyl nitrate administration also resulted in activation of extracellular signal regulated kinases (ERK), Akt, and c-Jun N-terminal kinases (JNK) expression. All these changes were found to be time-dependent. The result of the current study suggests that uranyl nitrate induces acute renal injury by activation of apoptosis through JNK pathway, while the early activation of signaling molecules Akt and ERK promotes the tubular cell proliferation and cell survival. PMID- 30302619 TI - Low survival rate of young adult-born olfactory sensory neurons in the undamaged mouse olfactory epithelium. AB - Olfactory sensory neurons (OSNs) are generated throughout life from progenitor cells in the olfactory epithelium. OSN axons project in an odorant receptor specific manner to the olfactory bulb (OB), forming an ordered array of glomeruli where they provide sensory input to OB neurons. The tetracycline transactivator (tTA) system permits developmental stage-specific expression of reporter genes in OSNs and has been widely used for structural and functional studies of the development and plasticity of the mouse olfactory system. However, the cellular ages at which OSNs stop expressing reporters driven by the immature OSN-specific Ggamma8-tTA driver line and begin to express reporters driven by the mature OSN specific OMP-tTA driver line have not been directly determined. We pulse-labeled terminally dividing cells in the olfactory epithelium of 28-day-old (P28) mice with EdU and analyzed EdU labeling in OSNs expressing fluorescent reporter proteins under control of either the Ggamma8-tTA or OMP-tTA driver line 5-14 days later. Expression of OMP-tTA-driven reporters began in 6-day-old OSNs, while the vast majority of newborn OSNs did not express Ggamma8-tTA-driven fluorescent proteins beyond 8 days of cellular age. Surprisingly, we also found a low survival rate for P28-born OSNs, very few of which survived for more than 14 days. We propose that OSN survival requires the formation of stable synaptic connections and hence may be dependent on organismal age. PMID- 30302618 TI - The Expression of Hypoxia-Induced Gene 1 (Higd1a) in the Central Nervous System of Male and Female Rats Differs According to Age. AB - HIGD1A (hypoxia-induced gene domain protein-1a), a mitochondrial inner membrane protein present in various cell types, has been mainly associated with anti apoptotic processes in response to stressors. Our previous findings have shown that Higd1a mRNA is widely expressed across the central nervous system (CNS), exhibiting an increasing expression in the spinal cord from postnatal day 1 (P1) to 15 (P15) and changes in the distribution pattern from P1 to P90. During the first weeks of postnatal life, the great plasticity of the CNS is accompanied by cell death/survival decisions. So we first describe HIGD1A expression throughout the brain during early postnatal life in female and male pups. Secondly, based on the fact that in some areas this process is influenced by the sex of individuals, we explore HIGD1A expression in the sexual dimorphic nucleus (SDN) of the medial preoptic area, a region that is several folds larger in male than in female rats, partly due to sex differences in the process of apoptosis during this period. Immunohistochemical analysis revealed that HIGD1A is widely but unevenly expressed throughout the brain. Quantitative Western blot analysis of the parietal cortex, diencephalon, and spinal cord from both sexes at P1, P5, P8, and P15 showed that the expression of this protein is predominantly high and changes with age but not sex. Similarly, in the sexual dimorphic nucleus, the expression of HIGD1A varied according to age, but we were not able to detect significant differences in its expression according to sex. Altogether, these results suggest that HIGD1A protein is expressed in several areas of the central nervous system following a pattern that quantitatively changes with age but does not seem to change according to sex. PMID- 30302621 TI - Tolerability of mycophenolate sodium in renal transplant recipients. AB - Background Kidney transplant recipients (KTR) receive fixed daily doses of mycophenolate sodium as part of the immunosuppressive regimen. Dose reductions occur primarily due to adverse events and may be associated with an increased risk of acute rejection and graft loss. Objectives To evaluate the tolerability of mycophenolate in kidney transplant recipients receiving tacrolimus and prednisone. Setting The study was performed at Hospital do Rim, Federal University of Sao Paulo in Brazil. Method This was a retrospective cohort study including 506 patients. Tolerability of mycophenolate sodium was classified into the following groups: Temporary reduction (TR), definitive reduction (DR), temporary interruption (TI), permanent discontinuation (PD) and without modification (WM). Main outcome measure The cause of mycophenolate dose change and its influence on rejection-free survival during the first 3 years after transplantation. Results The cumulative incidence of dose change was 51.2% (11%TR, 44%DR, 24%TI, and 21%PD). Gastrointestinal (45.3%), infection (31.9%) and hematological (14.9%) systems accounted for most of the dose changes. The adverse events with higher incidence were diarrhea, cytomegalovirus (CMV) infection and leukopenia. Changes in dose of mycophenole were associated with reduced acute rejection-free survival compared with patients WM group (71.4%TR, 58.9%DR, 56.7%TI, 53.7%PD vs. 74.2%WM, p = 0.020). Only patients with PD showed inferior patient (59.3% vs. 94.4%, p = 0.001) and death-censored graft (83.3% vs. 92.5%, p = 0.074) survivals compared to patients WM. Conclusion In this cohort, changes in the dose of mycophenolate were associated with increased risk of acute rejection and permanent discontinuation was associated with inferior patient and graft survival. PMID- 30302620 TI - Association of matrix metalloproteinase 3 and endogenous inhibitors with inflammatory markers in mitral valve disease and calcification. AB - Calcific mitral valve stenosis (MVS) is a common disease characterized by extensive remodeling of the extracellular matrix via matrix metalloproteinases (MMPs). The mechanism of calcification due to extensive matrix remodeling remains unclear. In this study, we investigated the relationship between MMP-3, tissue inhibitors of metalloproteinases (TIMPs) as well as pro-inflammatory cytokines and the phenomenon of calcification in MVS. 212 patients having rheumatic mitral stenosis (RMS) and 155 healthy control subjects were recruited in the Cardiology Department of La Rabta Hospital University. Levels of MMP-3, TIMPs, IL-6 and TNF alpha were measured by ELISA sandwich assay, hs-CRP was measured by immunoturbidimetry. Plasma levels of MMP-3, TIMP-1 and MMP-3/TIMP-2 ratio were lower only in RMS women in comparison to the control group. Calcification degree correlated positively with MMP-3 in women and men. In addition, calcification was correlated positively with MMP-3/TIMPs ratio in women patients. The inflammatory parameters were positively associated with extracellular matrix turnover biomarkers in men patients. In patients, the level of MMP-3 was increased in men and women with a calcification score >= 5. In addition, MMP-3 level predicted the occurrence of calcification. At ROC curves analysis, the cut-off MMP-3 level was in women was 9.21 ng/ml (sensitivity 51.1%, specificity 89.3%) and in men was 12.84 ng/ml (sensitivity 78.6%, specificity 77.8%). The high levels of MMP-3 and the biomarkers of inflammation contribute to valvular remodeling and calcification of the mitral valve. PMID- 30302622 TI - Correlates of Emergency Department Service Utilization Among U.S. Chinese Older Adults. AB - Older adults visit emergency departments (EDs) at a disproportionally higher rate than other age groups. Prior studies examining racial disparities in ED utilization focus on African Americans and Hispanics. There is a dearth of information on ED utilization patterns among older Asian Americans despite the evidence that ED expenditures in Asian Americans are comparable to that of Caucasians. To address this knowledge gap, we examined factors associated with ED service utilization in the largest Asian subgroup, U.S. Chinese older adults. Cross-sectional data from the Population Study of Chinese Elderly in Chicago (PINE) (N = 3,157) were used. Multivariate negative binomial regression analyses were conducted to examine significant factors associated with ED use. Higher education (rate ratio [RR] = 1.03, 95% confidence interval [CI] 1.00-1.05) and acculturation levels (RR = 1.02, CI 1.00-1.04), fewer people in the household (RR = 0.94, CI 0.88-0.99), health insurance coverage (RR = 1.34, CI 1.01-1.78), lower income (RR = 0.89, CI 0.80-0.99), poorer perceived health (RR = 0.67, CI 0.58 0.77), more functional limitations (RR = 1.09, CI 1.06-1.13) and depressive symptoms (RR = 1.04, CI 1.02-1.07), and a history of heart disease (RR = 2.28, CI 1.83-2.84), stroke (RR = 1.68, CI 1.20-2.35), cancer (RR = 1.86, CI 1.31-2.63), and hip fracture (RR = 1.42, CI 1.02-1.98) were associated with higher rates of ED visits. Our findings highlight several significant correlates of ED use in U.S. Chinese older adults. Culturally-appropriate interventions modifying these factors have the potential to decrease ED visits and improve care outcomes in this population. PMID- 30302623 TI - Effect of Varying Viscosity on Two-Fluid Model of Blood Flow through Constricted Blood Vessels: A Comparative Study. AB - PURPOSE: Most of the previously studied non-Newtonian blood flow models considered blood viscosity to be constant but for correct measurement of flow rate and flow resistance, the hematocrit dependent viscosity will be better as various literature suggested the variable nature of blood viscosity. Present work concerns the steady and pulsatile nature of blood flow through constricted blood vessels. Two-fluid model for blood is considered with the suspension of all the RBCs (erythrocytes) in the core region as a non-Newtonian (Herschel-Bulkley) fluid and the plasma in the cell free region near wall as a Newtonian fluid. No slip condition on the wall and radially varying viscosity has been taken. METHODS: For steady flow the analytical approach has been taken to obtain the exact solution. Regular perturbation expansion method has been used to solve the governing equations for pulsatile flow up to first order of approximation by assuming the pulsatile Reynolds number to be very small (much less than unity). RESULTS: Flow rate, wall shear stress and velocity profile have been graphically analyzed and compared with constant viscosity model. A noteworthy observation of the present study is that rise in viscosity index leads to decay in velocity, velocity of plug flow region, flow rate while flow resistance increases with rising viscosity index (m). The results for Power-law fluid (PL), Bingham-plastic fluid (BP), Newtonian fluid (NF) are found as special cases from this model. Like the constant viscosity model, it has been also observed that the velocity, flow rate and plug core velocity of two-fluid model are higher than the single-fluid model for variable viscosity. CONCLUSIONS: The two-phase fluid model is more significant than the single-fluid model. Effect of viscosity parameter on various hemodynamical quantities has been obtained. It is also concluded that a rising viscosity parameter (varying nature of viscosity) significantly distinguishes the single and two-fluid models in terms of changes in blood flow resistance. The outcome of present study may leave a significant impact on analyzing blood flow through small blood vessels with constriction, where correct measurement of flow rate and flow resistance for medical treatment is very important.

AB - Ylang-ylang oil (YYO) from Cananga odorata (Lam.) Hook.f. & Thomson and star anise oil (SAO) from Illicium verum Hook.f. were tested at four concentrations 0.05, 0.1, 0.2, 0.4 ul/cm2. Mortality rates were obtained by counting dead nymphs at 30-min intervals during the first 5 h after the start of exposure and then at 24, 48 and 72 h. Mortality increased with increasing oil concentration and time of exposure. The two highest concentrations of YYO (0.2, 0.4 ul/cm2) gave maximum lethal concentrations (LC) of 50 and 95% mortality after 4.5 h exposure. Mortality of 95% was obtained after 24 h with the next highest dose (0.1 ul/cm2), whereas LC95 required 3 days with the lowest YYO (0.05 ul/cm2). The lethal effect time (LT) was correlated with the duration of exposure, with a significant effect at 0.4 MUl YYO/cm2 after 3 h' (LT50 = 3.2 h, LT95 = 4.3 h). In contrast, only the highest concentration of SAO, 0.4 ul SAO/cm2, showed increasing mortality with time of exposure. This reached LT50 after 10 h and LT95 after 24 h. However, with the lower concentration (0.2 ul/cm2) 50% mortality was reached after 24 h and 100% at 72 h. At to the lowest concentration of SAO (0.1 ul/cm2), 67% mortality after 48 h. The study indicates that YYO and SAO exhibit strong acaricidal properties against nymphs of I. ricinus and suggest that both YYO and SAO should be evaluated as potentially useful in the control of ticks. PMID- 30302626 TI - Ixodes heathi n. sp. (Acari: Ixodidae), a co-endangered tick from the critically endangered mountain pygmy possum (Burramys parvus), with notes on its biology and conservation. AB - A new species of co-endangered tick, Ixodes heathi n. sp., is described from specimens of the nymph collected on the critically endangered mountain pygmy possum (Burramys parvus Broom) from the alpine region of Victoria, Australia. Its biology is discussed along with strategies for its conservation. PMID- 30302627 TI - Differential expression analysis for subolesin in Rhipicephalus microplus infected with Anaplasma marginale. AB - Rhipicephalus microplus (formerly Boophilus microplus) ticks are potential vectors of several pathogens of livestock especially in tropical and subtropical regions where may have substantial effects on economic development. Among tick borne pathogens, Anaplasma marginale is considered one of the most important in domestic and wild ruminants worldwide. Different molecular mechanisms have been employed by both ticks and these intracellular pathogens, in order to be able to adapt and survive. Subolesin, originally called 4D8, is an evolutionarily well preserved protein among ixodid tick species. This new antigen was found to be protective against tick infestations when used as a vaccine, as it has an essential role in tick blood digestion, development and infection of host cells by A. marginale. Recent studies have demonstrated that infection of both tick and vertebrate host cells with this microorganism changed gene expression. Therefore, the main objective of this study was to investigate subolesin expression in uninfected and A. marginale-infected R. microplus salivary glands by real-time reverse transcriptase (RT)-PCR. To analyze the differential expression of the recombinant protein subolesin, the gene was previously expressed from ticks infected with A. marginale. Results from this study revealed that, the expression of subolesin was significantly higher in salivary glands of infected R. microplus in comparison to uninfected ones. PMID- 30302629 TI - Pantoprazole Induces Mitochondrial Apoptosis and Attenuates NF-kappaB Signaling in Glioma Cells. AB - Gastric H+/K+-ATPase or vacuolar-ATPases (V-ATPases) are critical for the cancer cells survival and growth in the ischemic microenvironment by extruding protons from the cell. The drugs which inhibit V-ATPases are known as proton pump inhibitors (PPIs). In the present study, we aimed to evaluate the anticancer efficacy of pantoprazole (PPZ) and its consequences on NF-kappaB signaling in glioma cells. We have used MTT and clonogenic assay to show PPZ effect on glioma cell growth. Propidium iodide and rhodamine 123 staining were performed to demonstrate cell cycle arrest and mitochondrial depolarization. TUNEL staining was used to evidence apoptosis after PPZ treatment. Immunoblotting and immunofluorescence microscopy were performed to depict protein levels and localization, respectively. Luciferase assay was performed to confirm NF-kappaB suppression by PPZ. Our results revealed PPZ treatment inhibits cell viability or growth and induced cell death in a dose- and time-dependent manner. PPZ exposure arrested G0/G1 cyclic phase and increased TUNEL positivity, caspase-3 and PARP cleavage with altered pro and anti-apoptotic proteins. PPZ also induced ROS levels and depolarized mitochondria (Deltapsim) with increased cytosolic cytochrome c level. Further, PPZ suppressed TNF-alpha stimulated NF-kappaB signaling by repressing p65 nuclear translocation. NF-kappaB luciferase reporter assays revealed significant inhibition of NF-kappaB gene upon PPZ treatment. PPZ exposure also reduced the expression of NF-kappaB-associated genes, such as cyclin-D1, iNOS, and COX-2, which indicate NF-kappaB inhibition. Altogether, the present study disclosed that PPZ exerts mitochondrial apoptosis and attenuates NF kappaB signaling suggesting PPZ can be an effective and safe anticancer drug for glioma. PMID- 30302630 TI - Steroids in Stroke with Special Reference to Progesterone. AB - Both sex and steroid hormones are important to consider in human ischemic stroke and its experimental models. Stroke initiates a cascade of changes that lead to neural cell death, but also activates endogenous protective processes that counter the deleterious consequences of ischemia. Steroids may be part of these cerebroprotective processes. One option to provide cerebroprotection is to reinforce these intrinsic protective mechanisms. In the current review, we first summarize studies describing sex differences and the influence of steroid hormones in stroke. We then present and discuss our recent results concerning differential changes in endogenous steroid levels in the brains of male and female mice and the importance of progesterone receptors (PR) during the early phase after stroke. In the third part, we give an overview of experimental studies, including ours, that provide evidence for the pleiotropic beneficial effects of progesterone and its promising cerebroprotective potential in stroke. We also highlight the key role of PR signaling as well as potential additional mechanisms by which progesterone may provide cerebroprotection. PMID- 30302628 TI - Oxidative Imbalance, Nitrative Stress, and Inflammation in C6 Glial Cells Exposed to Hexacosanoic Acid: Protective Effect of N-acetyl-L-cysteine, Trolox, and Rosuvastatin. AB - X-linked adrenoleukodystrophy (X-ALD) is an inherited neurometabolic disorder caused by disfunction of the ABCD1 gene, which encodes a peroxisomal protein responsible for the transport of the very long-chain fatty acids from the cytosol into the peroxisome, to undergo beta-oxidation. The mainly accumulated saturated fatty acids are hexacosanoic acid (C26:0) and tetracosanoic acid (C24:0) in tissues and body fluids. This peroxisomal disorder occurs in at least 1 out of 20,000 births. Considering that pathophysiology of this disease is not well characterized yet, and glial cells are widely used in studies of protective mechanisms against neuronal oxidative stress, we investigated oxidative damages and inflammatory effects of vesicles containing lecithin and C26:0, as well as the protection conferred by N-acetyl-L-cysteine (NAC), trolox (TRO), and rosuvastatin (RSV) was assessed. It was verified that glial cells exposed to C26:0 presented oxidative DNA damage (measured by comet assay and endonuclease III repair enzyme), enzymatic oxidative imbalance (high catalase activity), nitrative stress [increased nitric oxide (NO) levels], inflammation [high Interleukin-1beta (IL-1beta) levels], and induced lipid peroxidation (increased isoprostane levels) compared to native glial cells without C26:0 exposure. Furthermore, NAC, TRO, and RSV were capable to mitigate some damages caused by the C26:0 in glial cells. The present work yields experimental evidence that inflammation, oxidative, and nitrative stress may be induced by hexacosanoic acid, the main accumulated metabolite in X-ALD, and that antioxidants might be considered as an adjuvant therapy for this severe neurometabolic disease. PMID- 30302631 TI - In Vitro Skin Retention and Drug Permeation through Intact and Microneedle Pretreated Skin after Application of Propranolol Loaded Microemulsions. AB - PURPOSE: Topical beta-blockers are efficacious for treating infantile hemangiomas, but no formulations have been specifically optimized for skin delivery. Our objective was to quantify skin concentrations and drug permeation of propranolol (a nonselective beta-blocker) after application of microemulsions to intact and microneedle pretreated skin. METHODS: Four propranolol-loaded microemulsions were characterized for droplet size, surface charge, conductivity, pH, drug solubility, and drug release. Skin concentrations and drug permeation through skin were quantified using LC-MS. Skin-to-receiver ratios were used to compare the microemulsion formulations to a drug-in-PBS solution. RESULTS: Propranolol solubility was significantly greater in microemulsions vs PBS. Cumulative drug release from the microemulsions over 24 h ranged from 13 to 26%. Skin concentrations and drug permeation through intact skin was significantly higher from PBS; however, the skin-to-receiver ratios were significantly higher for water-rich microemulsions compared to PBS or surfactant-rich microemulsions. Microneedle pretreatment significantly increased skin concentrations for all formulations. Skin-to-receiver ratios significantly increased after microneedle pretreatment for surfactant-rich microemulsions. CONCLUSIONS: Microemulsion formulation can be altered to elicit different drug delivery profiles through MN treated skin. This could be advantageous for maximizing local skin drug concentrations and improving dosing schedules for infantile hemangioma treatment. PMID- 30302633 TI - Accuracy of an artificial neural network for detecting a regional abnormality in myocardial perfusion SPECT. AB - OBJECTIVES: The patient-based diagnosis with an artificial neural network (ANN) has shown potential utility for the detection of coronary artery disease; however, the region-based accuracy of the detected regions has not been fully evaluated. The aim of this study was to demonstrate the accuracy of all detected regions compared with expert interpretation. METHODS: A total of 109 abnormal regions including 33 regions with stress defects and 76 regions with ischemia were examined, which were derived from 21 patients who underwent myocardial perfusion SPECT within 45 days of coronary angiography. The gray and color scale images, a polar map of stress, rest and difference, and left ventricular function were displayed on the monitor to score the extent and severity of stress defect and ischemia. Two experienced nuclear medicine physicians (Observers A and B) scored the abnormality with a 4-point scale and draw abnormal regions on a polar map. The gold standard was determined by the final judgment of normal or abnormal by the consensus of two other independent expert nuclear cardiologists, and was compared with the stress defect and ischemia derived from ANN. RESULTS: The concordance rate of ANN to the gold standard was higher than that of two observers. Furthermore, the kappa coefficient indicated moderate to substantial agreement for stress defect and slight to the fair agreement for ischemia. The area under the curve (AUC) of ANN was the highest for both stress defect and ischemia; in particular, the ANN of ischemia showed significantly higher AUC than Observer A (p = 0.005). The ANN of stress defect showed higher specificity compared with two observers, while the ANN of ischemia showed higher sensitivity. Consequently, the accuracy of ANN showed the highest in this study. CONCLUSION: The ANN-based regional diagnosis showed a high concordance rate with the gold standard and comparable or even higher than the interpretation by nuclear medicine physicians. PMID- 30302632 TI - Expression, Purification, and Characterization of Recombinant Human alpha1 Antitrypsin Produced Using Silkworm-Baculovirus Expression System. AB - Human alpha1-antitrypsin (AAT) is the most abundant serine proteinase inhibitor (serpin) in the human plasma. Commercially available AAT for the medications of deficiency of alpha1-antitrypsin is mainly purified from human plasma. There is a high demand for a stable and low-cost supply of recombinant AAT (rAAT). In this study, the baculovirus expression vector system using silkworm larvae as host was employed and a large amount of highly active AAT was recovered from the silkworm serum (~ 15 mg/10 ml) with high purity. Both the enzymatic activity and stability of purified rAAT were comparable with those of commercial product. Our results provide an alternative method for mass production of the active rAAT in pharmaceutical use. PMID- 30302634 TI - Differential diagnosis of thickened myocardium: an illustrative MRI review. AB - OBJECTIVES: The purpose of this article is to describe the key cardiac magnetic resonance imaging (MRI) features to differentiate hypertrophic cardiomyopathy (HCM) phenotypes from other causes of myocardial thickening that may mimic them. CONCLUSIONS: Many causes of myocardial thickening may mimic different HCM phenotypes. The unique ability of cardiac MRI to facilitate tissue characterisation may help to establish the aetiology of myocardial thickening, which is essential to differentiate it from HCM phenotypes and for appropriate management. TEACHING POINTS: * Many causes of myocardial thickening may mimic different HCM phenotypes. * Differential diagnosis between myocardial thickening aetiology and HCM phenotypes may be challenging. * Cardiac MRI is essential to differentiate the aetiology of myocardial thickening from HCM phenotypes. PMID- 30302635 TI - Imaging presentation of pancreatic neuroendocrine neoplasms. AB - Pancreatic neuroendocrine neoplasms (P-NENs) are the second most common solid pancreatic neoplasms. P-NENs have a wide range of imaging features presentations and they can be detected with typical and atypical imaging presentations. Typical and atypical appearances can be explained by pathologic correlations. P-NENs are generally hypervascular lesions, showing a typical enhancement behavior after contrast media injection during imaging methods, but they could also have different imaging features, creating some difficulty in differential diagnosis. For this reason, radiologists should be aware of different imaging presentations of these neoplasms. Radiological evaluation has a critical role in P-NENs identification, characterization, and staging of these neoplasms, especially in those cases in which surgery is the treatment of choice. The present paper shows, indicating the underlying pathologic correlations, typical and atypical presentations of NENs. KEY POINTS: * P-NENs have a wide range of imaging features presentations, typical and atypical. * Pathology could help in better understanding the typical P-NENs appearance at imaging. * P-NENs are generally hypervascular lesions. * Radiological evaluation has a critical role in P-NENs identification and management. * Radiologists should know every type of different imaging presentation of P-NENs to better diagnose these kinds of lesions. PMID- 30302636 TI - Sensitivity Analysis for Multiscale Stochastic Reaction Networks Using Hybrid Approximations. AB - We consider the problem of estimating parameter sensitivities for stochastic models of multiscale reaction networks. These sensitivity values are important for model analysis, and the methods that currently exist for sensitivity estimation mostly rely on simulations of the stochastic dynamics. This is problematic because these simulations become computationally infeasible for multiscale networks due to reactions firing at several different timescales. However it is often possible to exploit the multiscale property to derive a "model reduction" and approximate the dynamics as a Piecewise deterministic Markov process, which is a hybrid process consisting of both discrete and continuous components. The aim of this paper is to show that such PDMP approximations can be used to accurately and efficiently estimate the parameter sensitivity for the original multiscale stochastic model. We prove the convergence of the original sensitivity to the corresponding PDMP sensitivity, in the limit where the PDMP approximation becomes exact. Moreover, we establish a representation of the PDMP parameter sensitivity that separates the contributions of discrete and continuous components in the dynamics and allows one to efficiently estimate both contributions. PMID- 30302637 TI - Postoperative Complications Independently Predict Cancer-Related Survival in Peritoneal Malignancies. AB - BACKGROUND: The authors hypothesized that postoperative complications after cytoreductive surgery-hyperthermic intraperitoneal chemoperfusion (CRS-HIPEC) have a negative impact on perioperative and oncologic outcomes and that the novel Comprehensive Comorbidity Index (CCI) would be a better predictor of such outcomes than the traditional Clavien-Dindo classification (CDC). METHODS: The study used a prospective database of 1296 patients with peritoneal metastases (PM) undergoing CRS-HIPEC between 2001 and 2016. The Kaplan-Meier method was used to estimate survival. Multivariate analyses identified associations with perioperative and oncologic outcomes. The Akaike information criterion and the Schwarz (Bayesian information) criterion were used to compare model fitting for CCI versus CDC. RESULTS: In this study, CRS-HIPEC was performed for malignant mesothelioma (12%) and PM from appendix (50%), colorectal (30%), and ovarian (8%) cancers. Major postoperative in-hospital complications (CDC grades 3-4) occurred for 24% of the patients. However, a range of CCI scores was calculated for each CDC grade because 36% of the patients experienced multiple complications. After a median follow-up period of 55 months, the median progression-free survival was 15 months, and the median overall survival was 39 months. In the multivariate Cox proportional hazards models, postoperative in-hospital complications (measured by CDC or CCI) were independent prognostic factors for 30-day post-discharge morbidity and readmission, as well as for survival. The CCI scores demonstrated higher prognostic sensitivity for these outcomes than CDC grades. CONCLUSIONS: Reduction of postoperative complications after CRS-HIPEC is essential for optimal short- and long-term outcomes. For assessing total burden of postoperative complications per patient, CCI is superior to CDC and more sensitive for assessing surgery- and cancer-related outcomes after CRS-HIPEC.

PMID- 30302643 TI - Both Ultrasound Features and Nuclear Atypia are Associated with Malignancy in Thyroid Nodules with Atypia of Undetermined Significance. AB - BACKGROUND: The optimal management of thyroid nodules that undergo fine-needle aspiration (FNA) with findings of atypia of undetermined significance (AUS) is unclear. Categorizing nodules by AUS subtype and ultrasound characteristics may improve risk stratification. Therefore, the purpose of this study is to evaluate the association between AUS subtype and ultrasound features on risk of malignancy (ROM). METHODS: We performed a review of all patients with a thyroid nodule who underwent an FNA at our institution between January 2010 and November 2015. Patients with AUS were divided into groups with (1) nuclear atypia, (2) architectural atypia, or (3) Hurthle cell atypia. Their ultrasound features were assessed using the American Thyroid Association (ATA) thyroid nodule sonographic patterns. We conducted a univariate and multivariable analysis to determine the association between AUS subtype and other variables of interest with ROM. RESULTS: Of the 3428 thyroid nodules that underwent FNA, 237 (6.9%) had AUS. Of the 97 surgically resected nodules, 67 (69%) were benign and 30 (31%) were malignant. On univariate analysis nuclear atypia (p < 0.01) was associated with a thyroid malignancy. On multivariable analysis, both ATA high-risk ultrasound features (p = 0.04, odds ratio [OR] 3.68) and nuclear atypia (p < 0.01, OR 11.8) were independently associated with a final diagnosis of thyroid carcinoma. CONCLUSIONS: Nuclear atypia and ATA high-risk ultrasound features are useful in identifying patients with AUS that are at a higher risk of thyroid malignancy. Surgeons should take these factors into consideration when evaluating patients with AUS.

AB - An iridescent yellow pigmented bacterium isolated from the Antarctic continent, named Cellulophaga fucicola strain 416, was found to be able to tolerate UV-B radiation. Its crude pigment extract was tested for antioxidant capacity, UV light stability and phototoxicity profile against murine fibroblast lines. The pigments were further isolated and chemically identified by ultra-high performance liquid chromatography with photodiode array and mass spectrometry detectors. The results showed that the pigment extract presented weak stability under exposure to UV light, a phototoxic profile in the 3t3 Neutral Red Uptake test and a very high antioxidant activity, suggesting that it could be used as food and feed colourants. Zeaxanthin and two isomers of zeaxanthin, beta cryptoxanthin and beta-carotene, were identified using a C18 column. These five carotenoids were the major pigments isolated from C. fucicola 416. In conclusion, the identification of pigments produced by the bacterial strain under study may help us understand how bacteria thrive in high UV and cold environments, and opens avenues for further biotechnological application towards a more sustainable and environmentally friendly way of pigment exploitation. PMID- 30302648 TI - Streptomyces monticola sp. nov., a novel actinomycete isolated from soil. AB - A novel actinobacterium, designated strain NEAU-GS4T, was isolated from soil collected from Mount Song and characterised using a polyphasic approach. 16S rRNA gene sequence similarity studies showed that strain NEAU-GS4T belongs to the genus Streptomyces, being closely related to Streptomyces spectabilis JCM 4308T (98.8%), Streptomyces sclerotialus DSM 43032T (98.3%) and Streptomyces lasiicapitis 3H-HV17(2)T (98.0%). A multilocus sequence analysis based on five house-keeping genes (atpD, gyrB, rpoB, recA and trpB) also indicated that strain NEAU-GS4T should be assigned to the genus Streptomyces. The major menaquinones were identified as MK-9(H6), MK-9(H8) and MK-9(H4). The polar lipid profile was found to contain diphosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine, phosphatidylinositolmannosides and an unidentified phospholipid. The major fatty acids were identified as anteiso-C15:0, iso-C16:0 and anteiso-C17:0. Moreover, DNA-DNA hybridization results and some phenotypic characteristics indicated that strain NEAU-GS4T can be clearly differentiated from its closely related species of the genus Streptomyces. Therefore, it is concluded that strain NEAU-GS4T represents a novel species of the genus of Streptomyces, for which the name Streptomyces monticola sp. nov. is proposed. The type stain is NEAU-GS4T (=CGMCC 4.7467T = DSM 105116T). PMID- 30302649 TI - Characterization of a strain representing a new Enterobacter species, Enterobacter chengduensis sp. nov. AB - An Enterobacter strain, WCHECl-C4, was recovered from a human blood sample in China in 2015. Phylogenetic analysis based on multi-locus sequence analysis of the rpoB, gyrB, infB and atpD housekeeping genes revealed that the strain is distinct from any previously described species of the genus Enterobacter. The whole genome sequence of strain WCHECl-C4 has an 80.48-93.34% average nucleotide identity with those of type strains of all known Enterobacter species. In silico DNA-DNA hybridization (isDDH) values between strain WCHECl-C4 and type strains of all known Enterobacter species range from 23.2 to 52.4%. The major cellular fatty acids of strain WCHECl-C4 are C16:0, C17:0 cyclo and C18:1omega7c, which are in the range of Enterobacter species. The genomic DNA G + C content was 55.7 mol%. Strain WCHECl-C4 can be distinguished from all known Enterobacter species by its ability to ferment D-sorbitol, L-rhamnose and melibiose but with a negative Voges Proskauer reaction. Genotypic and phenotypic characteristics from this study indicate that strain WCHECl-C4 represents a novel species of the genus Enterobacter, for which the name Enterobacter chengduensis sp. nov. is proposed. The type strain is WCHECl-C4T (= GDMCC1.1216T = CCTCC AB 2017105T = KCTC 52993T). PMID- 30302651 TI - Risk of multiple colorectal cancer development depends on age and subgroup in individuals with hereditary predisposition. AB - Development of multiple colorectal cancers (CRCs), synchronously or metachronously, is associated with hereditary predisposition for cancer and accurate risk estimates of multiple tumour development are relevant to recommend rational surveillance programs. A cross-sectional study design was used to estimate the risks of synchronous CRC (SCRC) and metachronous CRC (MCRC) based on data from the National Danish Hereditary Nonpolyposis Register. In total, 7100 individuals from families within the subgroups Lynch syndrome, familial CRC (FCC) and moderate risk were used with estimates relative to a non-hereditary population control cohort. SCRC was diagnosed in 7.4% of the Lynch syndrome cases, in 4.2% of FCC cases and 2.5% of the moderate risk cases, which translated to relative risks of 1.9-5.6. The risk of MCRC was distinctively linked to Lynch syndrome with a life-time risk up to 70% and an incidence rate ratio of 5.0. The risk of SCRC was significantly increased in all subgroups of FCC and hereditary CRC, whereas the risk of MCRC was specifically linked to Lynch syndrome. These observations suggest that individuals with FCC or hereditary CRC should be carefully screened for second primary CRC at the time of diagnosis, whereas intensified surveillance for second primary CRC is motivated in Lynch syndrome with lower-intensity programs in families with yet unidentified genetic causes. PMID- 30302650 TI - Marinobacter profundi sp. nov., a slightly halophilic bacterium isolated from a deep-sea sediment sample of the New Britain Trench. AB - A piezotolerant, cold-adapted, slightly halophilic bacterium, designated strain PWS21T, was isolated from a deep-sea sediment sample collected from the New Britain Trench. Cells were observed to be Gram-stain negative, rod-shaped, oxidase- and catalase-positive. Growth of the strain was observed at 4-45 degrees C (optimum 37 degrees C), at pH 5.0-9.0 (optimum 7.0) and in 0.5-20% (w/v) NaCl (optimum 3-4%). The optimum pressure for growth was 0.1 MPa (megapascal) with tolerance up to 70 MPa. 16S rRNA gene sequence analysis showed that strain PWS21T is closely related to Marinobacter guineae M3BT (98.4%) and Marinobacter lipolyticus SM19T (98.2%). Multilocus sequence analysis (MLSA) based on sequences of housekeeping genes gyrB, recA, atpD, rpoB and rpoD indicates that strain PWS21T represents a distinct evolutionary lineage within the genus Marinobacter. Furthermore, strain PWS21T showed low ANI and diDDH values to the closely related species. The principal fatty acids were identified as C12:0, C12:0 3-OH, C16:1omega9c, C16:0 and C18:1omega9c. Ubiquinone-9 was identified as the major respiratory quinone. The polar lipids were identified as phosphatidylethanolamine (PE), phosphatidylglycerol (PG), diphosphatidylglycerol (DPG), aminophospholipid (APL), two unidentified lipids and an unidentified phospholipid (PL). The G + C content of the genomic DNA was determined to be 60.3 mol%. On the basis of phenotypic, chemotaxonomic and molecular data, we conclude that strain PWS21T represents a novel species of the genus Marinobacter, for which the name Marinobacter profundi sp. nov. is proposed (type strain PWS21T = KCTC 52990T = MCCC 1K03345T). PMID- 30302652 TI - Boosting care and knowledge about hereditary cancer: European Reference Network on Genetic Tumour Risk Syndromes. AB - Approximately 27-36 million patients in Europe have one of the ~ 5.000-8.000 known rare diseases. These patients often do not receive the care they need or they have a substantial delay from diagnosis to treatment. In March 2017, twenty four European Reference Networks (ERNs) were launched with the aim to improve the care for these patients through cross border healthcare, in a way that the medical knowledge and expertise travels across the borders, rather than the patients. It is expected that through the ERNs, European patients with a rare disease get access to expert care more often and more quickly, and that research and guideline development will be accelerated resulting in improved diagnostics and therapies. The ERN on Genetic Tumour Risk Syndromes (ERN GENTURIS) aims to improve the identification, genetic diagnostics, prevention of cancer, and treatment of European patients with a genetic predisposition for cancer. The ERN GENTURIS focuses on syndromes such as hereditary breast cancer, hereditary colorectal cancer and polyposis, neurofibromatosis and more rare syndromes e.g. PTEN Hamartoma Tumour Syndrome, Li Fraumeni Syndrome and hereditary diffuse gastric cancer. PMID- 30302653 TI - Endoscopic Ultrasound-Directed Transgastric ERCP (EDGE): a Single-Center US Experience with Follow-up Data on Fistula Closure. AB - BACKGROUND: Endoscopic ultrasound-directed transgastric ERCP (EDGE) by creating an anastomosis from the gastric pouch or jejunum to the excluded stomach allows performance of ERCP in Roux-en-Y gastric bypass (RYGB) anatomy. Concern for persistent fistula following stent removal and sparse data limit adoption. METHODS: Retrospective review of consecutive patients undergoing EDGE over a 2 year period. RESULTS: Nineteen RYGB patients underwent EDGE; three had previously failed ERCP by the device-assisted method. Indications for ERCP were choledocholithiasis (8), recurrent acute pancreatitis (6), benign post-surgical stricture (3), elevated bilirubin, and papillary stenosis (1 each). EDGE was technically successful in all 19 patients with jejunogastric anastomosis in 11 patients and gastrogastric in 8 using a 15-mm lumen-apposing metal stent. Stent malposition occurred in six and was managed by rescue maneuvers. ERCP was performed in the same session in four patients; the remainder were delayed after a mean of 48 days. Diagnostic endoscopic ultrasound (EUS) was performed in four patients. No severe adverse events occurred; clinical success was 100%. Stents were removed after a mean dwell time of 182 days. Argon plasma coagulation (APC) was used to promote fistula closure in 12 patients. Upper GI series to assess fistula closure was obtained in 11 patients after a mean of 182 days following stent removal. One persistent fistula was identified and closed endoscopically. CONCLUSIONS: EDGE is an effective modality for performing ERCP in patients with RYGB anatomy and can be performed via gastrogastric or jejunogastric approaches. Persistent fistula is uncommon and can be managed endoscopically. APC may promote fistula closure. PMID- 30302654 TI - Effect of hospital and surgeon volume on postoperative outcomes after distal gastrectomy for gastric cancer based on data from 145,523 Japanese patients collected from a nationwide web-based data entry system. AB - BACKGROUND: Despite interest in surgeon and hospital volume effects on distal gastrectomy, clinical significance has not been confirmed in a large-scale population. We studied to clarify the effects of surgeon and hospital volume on postoperative mortality after distal gastrectomy for gastric cancer among Japanese patients in a nationwide web-based data entry system. METHODS: We extracted data on distal gastrectomy for gastric cancer from the National Clinical Database between 2011 and 2015. The primary outcome was operative mortality. Hospital volume was divided into 3 tertiles: low (1-22 cases per year), medium (23-51) and high (52-404). Surgeon volume was divided into the 5 groups: 0-3, 4-10, 11-20, 21-50, 51 + cases per year. We calculated the 95% confidence interval (CI) for the mortality rate based on odds ratios (ORs) estimated from a hierarchical logistic regression model. RESULTS: We analyzed 145,523 patients at 2182 institutions. Operative mortality was 1.9% in low-, 1.0% in medium- and 0.5% in high-volume hospitals. The operative mortality rate decreased definitively with surgeon volume, 1.6% in the 0-3 group and 0.3% in the 51 + group. After risk adjustment for surgeon and hospital volume and patient characteristics, hospital volume was significantly associated with operative morality (medium: OR 0.64, 95% CI 0.56-0.73, P < 0.001; high: OR 0.42, 95% CI 0.35-0.51, P < 0.001). CONCLUSIONS: We demonstrate that hospital volume can have a crucial impact on postoperative mortality after distal gastrectomy compared with surgeon volume in a nationwide population study. These findings suggest that centralization may improve outcomes after distal gastrectomy. PMID- 30302655 TI - The Role of Gay-Related Stigma in HIV-Risk Behavior Among Sexual Minority Men in Europe. AB - Sexual orientation stigma stems from discriminatory social contexts and may ultimately impact the behavioral health of stigmatized individuals through stress related pathways. Sexual minority stigma is of particular concern in Europe given the diversity of social contexts on the continent and sexual minority men's rapidly increasing risk of HIV infection, especially in Central and Eastern Europe, potentially rooted in stigma. This study assesses whether stigma in the ubiquitous social contexts surrounding sexual minority men (e.g., family, workplace, government) may place them at higher risk for HIV contraction across six countries. We utilized a large cross-sectional survey sample of HIV-negative sexual minority men (N = 2087; mean age = 31.6, SD = 9.7) from six European countries to test whether those who reported sexual orientation stigma also engaged in more HIV risk-related behaviors, including condomless sex with casual partners (in the absence of PrEP) and substance use before and during sex. Regression analyses were performed in Mplus. We found that a one standard deviation increase in reported sexual orientation stigma was significantly associated with the following during the last sexual encounter: a 19% increase in odds of sex under the influence of alcohol, 27% increase in odds of sex under the influence of cannabis, 49% increase in odds of sex under the influence of illicit drugs, an 11% increase in odds of condomless sex with casual partners in the past 6 months, and a 26% increase in odds of knowing where to receive an HIV test. Sexual minority men who reported perceiving greater sexual orientation-related stigma within their ubiquitous social contexts were significantly more likely to report sexual risk and alcohol and drug use during their last sexual encounter, yet reported more knowledge of preventive services. Contextual stigma might serve as a precursor to behavioral risks of HIV infection, generating maladaptive stress responses capable of being modified through individually-focused interventions. Structural interventions are also needed to ultimately reduce stigma at its source.

AB - Network-based diffusion analysis (NBDA) has become a widely used tool to detect and quantify social learning in animal populations. NBDA infers social learning if the spread of a novel behavior follows the social network and hence relies on appropriate information on individuals' network connections. Most studies on animal populations, however, lack a complete record of all associations, which creates uncertainty in the social network. To reduce this uncertainty, researchers often use a certain threshold of sightings for the inclusion of animals (which is often arbitrarily chosen), as observational error decreases with increasing numbers of observations. Dropping individuals with only few sightings, however, can lead to information loss in the network if connecting individuals are removed. Hence, there is a trade-off between including as many individuals as possible and having reliable data. We here provide a tool in R that assesses the sensitivity of NBDA to error in the social network given a certain threshold for the inclusion of individuals. It simulates a social learning process through a population and then tests the power of NBDA to reliably detect social learning after introducing observational error into the social network, which is repeated for different thresholds. Our tool can help researchers using NBDA to select a threshold, specific to their data set, that maximizes power to reliably quantify social learning in their study population. PMID- 30302658 TI - Left ventricular assist device recovery: does duration of mechanical support matter? AB - Heart failure is a widespread condition in the United States that is predicted to significantly increase in prevalence in the next decade. Many heart failure patients are given a left ventricular assist device (LVAD) while they wait for a heart transplant, while those that are not able to undergo a heart transplant may be given an LVAD permanently. However, past studies have observed a small subset of heart failure patients that recovered cardiac function of their native heart after being placed on an LVAD. As a result, some patients have been able to have their LVAD explanted and no longer needed a heart transplant. In this review, we analyzed the data of 15 studies that observed recovery of cardiac function in LVAD patients in order to investigate the effects that duration of LVAD support has on patient outcomes. From our review, we identified that there may be negative consequences of prolonged duration of mechanical support such as myocardial atrophy and abnormal calcium cycling as well as circumstances that may allow for a longer duration of LVAD support such as in patients using a continuous-flow LVAD, non-ischemic cardiomyopathy patients, and the specific pharmacological therapy.

AB - Bioactive phospholipids, including sphingosine-1-phosphate (S1P), ceramide-1 phosphate (C1P), lysophosphatidylcholine (LPC), and its derivative lysophosphatidic acid (LPA), have emerged as important mediators regulating the trafficking of normal and cancer cells. While the role of S1P in regulating migration of hematopoietic cells is well established, in this work we compared its biological effects to the effects of C1P, LPC, and LPA. We employed 10 human myeloid and lymphoid cell lines as well as blasts from AML patients. We observed that human leukemic cells express functional receptors for phospholipids and respond to stimulation by phosphorylation of p42/44 MAPK and AKT. We also found that bioactive phospholipids enhanced cell migration and adhesion of leukemic cells by downregulating expression of HO-1 and iNOS in a p38 MAPK-dependent manner but did not affect cell proliferation. By contrast, downregulation of p38 MAPK by SB203580 enhanced expression of HO-1 and iNOS and decreased migration of leukemic cells in vitro and their seeding efficiency to vital organs in vivo after injection into immunodeficient mice. Based on these findings, we demonstrate that, besides S1P, human leukemic cells also respond to C1P, LPC, and LPA. Since the prometastatic effects of bioactive phospholipids in vivo were mediated, at least in part, by downregulating HO-1 and iNOS expression in a p38 MAPK-dependent manner, we propose that inhibitors of p38 MAPK or stimulators of HO-1 activity will find application in inhibiting the spread of leukemic cells in response to bioactive phospholipids. PMID- 30302661 TI - Self-propulsion of droplets driven by an active permeating gel. AB - We discuss the flow field and propulsion velocity of active droplets, which are driven by body forces residing on a rigid gel. The latter is modelled as a porous medium which gives rise to permeation forces. In the simplest model, the Brinkman equation, the porous medium is characterised by a single lengthscale [Formula: see text] --the square root of the permeability. We compute the flow fields inside and outside of the droplet as well as the energy dissipation as a function of [Formula: see text]. We furthermore show that there are optimal gel fractions, giving rise to maximal linear and rotational velocities. In the limit [Formula: see text], corresponding to a very dilute gel, we recover Stokes flow. The opposite limit, [Formula: see text], corresponding to a space filling gel, is singular and not equivalent to Darcy's equation, which cannot account for self propulsion. PMID- 30302662 TI - Transmucosal oxygen tension of the clitoris: a new parameter for future investigations of the sexual, metabolic, and cardiovascular health of women. AB - BACKGROUND: Several studies suggested that abnormalities in tissue perfusion of external genitalia and vagina can lead to female sexual dysfunctions (FSDs) and can be associated to metabolic and cardiovascular risk factors. However, there are some technical difficulties in assessing these abnormalities. The measurement of oxygen partial pressure is a noninvasive method to measure oxygen partial pressure (pO2) at the skin surface to assess tissue perfusion. The aim of this study was to evaluate whether transmucosal oxygen tension (TmPO2) can be measured at the mucosal surface of clitoris and whether the measurements are reliable. METHODS: TmPO2 was measured in six young healthy women by using a device to measure transcutaneous pO2 on the skin and by choosing a small sensor, usually used for newborns. The identical procedure for the detection of pO2 at the skin surface was used. RESULTS: The mean value of TmPO2 was 42.3 mmHg (range: 24.1 53.4 mmHg). All the trend curves of the TmPO2 showed the same behavior: after a stabilization time, there was a stable pO2 (plateau phase) that corresponds to the TmPO2 of the clitoris. These curves had a similar trend to those recorded at the skin surface. CONCLUSIONS: TmPO2 can be easily measured at the mucosal surface of clitoris. Large epidemiological studies in healthy and unhealthy women and in women with FSD are needed to establish both the normal range of TmPO2 and the meaning that different values of TmPO2 can have on sexual and general health of the women. PMID- 30302663 TI - Long-term sequelae of the less than total thyroidectomy procedures for benign thyroid nodular disease. AB - INTRODUCTION: Nodular goiter is the most common disorder of the thyroid gland. Less than total thyroidectomy procedures are considered the gold standard in the surgical management of nodular thyroid disease despite its propensity for recurrence. The aim of the study was to assess long-term sequelae of the less than total thyroidectomy procedures. MATERIAL AND METHODS: In this single-center retrospective study, records of 154 patients that underwent less than total thyroidectomy, for nodular disease and/or hyperthyroidism between 1998 and 2013, were reviewed. Patients with malignant findings in the histology report and a follow-up of less than 5 years were excluded. RESULTS: The mean age of the recorded patients was 65.1 +/- 12.91 years of which 132 were females. Subtotal thyroidectomy was performed in 45.5% of the study population, 22.1% underwent partial thyroidectomy, while the remaining 32.5% underwent lobectomy. Long-term thyroxine supplementation was administered in 138 patients (89.6%). Recurrence of clinically important nodules (>1 cm) was observed in 68.2% of patients but only 11% of the population underwent completion thyroidectomy. In the univariate analysis, the duration of follow-up (p = 0.00005, C.I.: 0.903-0.965) as well as the type of operation (p = 0.035, C.I.: 1.031-2.348) appeared to have a significant correlation with nodular recurrence. The multivariate analysis identified the duration of follow-up (p = 0.0005, C.I.: 0.908-0.973) as the only significant predictive factor of nodular recurrence. CONCLUSION: This is the first study with such a long duration of post-operative follow-up. The high rate of nodular recurrence in less than total thyroidectomy procedures along with the lifelong need for thyroxine supplementation suggest that a more conservative surgical approach is needed. When surgery is recommended, we suggest total thyroidectomy as the treatment of choice to avoid the recurrence of disease, the high cost associated with frequent follow-ups by means of sonography as well as thyroxine replacement therapy. PMID- 30302664 TI - Health-Related Quality of Life Following Concussion in Collegiate Student Athletes With and Without Concussion History. AB - The purpose of this study was to compare global and specific health-related quality of life (HRQOL) throughout concussion recovery between those with and without concussion history. Student-athletes diagnosed with concussion completed global (Short Form-12v2; SF-12) and specific (Hospital Anxiety and Depression Scale: HADS) HRQOL assessments at baseline, 24-48 h, asymptomatic, return-to play, and 6-months post-injury. Baseline scores were compared to post-injury time points for SF-12 subscores (physical and mental; PCS-12, MCS-12) and HADS subscores (depression and anxiety; HADS-D, HADS-A). We conducted a 2 * 5 mixed model ANOVA for group (with and without concussion history) and time (four post injury assessments compared to baseline). We did not observe interaction or main effects for group, except those with concussion history had worse HADS-D subscores than those without concussion history. PCS-12 subscores were worse at 24-48 h, asymptomatic, and return-to-play compared to baseline, but returned to baseline 6-months post-injury. MCS-12 subscores did not differ at any time points. HADS-D subscores worsened 24-48 h post-injury, but improved for additional assessments compared to baseline. HADS-A improved post-injury compared to baseline at asymptomatic, return-to-play, and 6-month assessments, but was similar to baseline 24-48 h post-injury. HRQOL physical aspects slightly worsened post-injury and restored to baseline after returning to play. PMID- 30302665 TI - Excitatory and inhibitory effects of stimulation of sacral dorsal root ganglion on bladder reflex in cats. AB - PURPOSE: To explore the effects of electrical stimulation of the sacral dorsal root ganglion (DRG) on bladder reflexes in alpha-chloralose-anesthetized cats. METHODS: Bladder activity was recorded under isovolumetric conditions. A pair of hook electrodes was placed in the right S1 and S2 DRGs of 12 adult male cats, which were stimulated over a range of frequencies (0.25-30 Hz) and at threshold intensity. RESULTS: Stimulation of S1 and S2 DRGs inhibited or evoked bladder contractions under isovolumetric conditions depending on the frequency of stimulation in nine cats. Stimulation at low frequencies (3-7 Hz on S1 or S2 DRG) significantly inhibited isovolumetric rhythmic bladder contractions, while excitatory effects were observed at two frequency ranges, including lower frequencies (0.25-1.5 Hz on S1 DRG and 0.25-1.25 Hz on S2 DRG) and middle frequencies (15-30 Hz on S1 and S2 DRGs). CONCLUSIONS: These results suggest that the sacral DRG might be a potential valuable target for electrical stimulation in the treatment of bladder dysfunction. PMID- 30302666 TI - The comparison of oxidative stress effect in classic and tubeless percutaneous nephrolithotomy. AB - PURPOSE: Surgical stone treatment induces oxidative stress in kidney tissue. We hypothesized that tubeless percutaneous nephrolithotomy (tPCNL) may induce less oxidative stress than classic percutaneous nephrolithotomy (cPCNL) with nephrostomy tube. METHODS: Seventy-two consecutive patients with kidney stones qualified for PCNL were enrolled in the study. Patients were assigned to one of two groups (first group 33 patients-cPCNL and second group 39 patients-tPCNL). Four urine samples were collected in four consecutive days, starting the day before operation. Four oxidative stress markers were analyzed in each sample: catalase (CAT), protein sulfhydryl group (SH), total antioxidant capacity (TAC) and superoxide dismutase (SOD). RESULTS: Baseline mean levels of CAT (IU/l), SH (MUmol/l), TAC (mmol/l) and SOD (NU/ml) were 19.4 versus 11.7; 18 versus 58.7; 2.02 versus 1.99; 20.5 versus 22.6 in cPCNL and tPCNL group, respectively. On day two, the levels were 89 versus 104.9; 334.7 versus 518.9; 1.87 versus 1.79; 33.7 versus 41.4, respectively. On the third day, the levels were: 67.4 versus 28.3; 206.8 versus 306.9; 2.01 versus 2.06; 38.2 versus 36.6, respectively. On the fourth day, the concentrations were 47.4 versus 18.5; 129.3 versus 208.7; 2 versus 2.06; 35 versus 45.2, respectively. Significant differences were observed only for CAT and TAC concentrations in days 3 (p = 0.04 and 0.04) and 4 (p = 0.02 and < 0.001) in favor of tPCNL. CONCLUSIONS: CAT, SH and SOD significantly rise after operation. TAC represents the inversion of other parameters. CAT is significantly lower, and TAC is significantly higher in tPCNL postoperatively favoring this method. PMID- 30302667 TI - Application of fractal theory and fuzzy enhancement in ultrasound image segmentation. AB - The manuscript describes an ultrasound image segmentation technique based on the fractional Brownian motion (FBM) model. Here, the ultrasound images are first enhanced using a fuzzy-based technique, and later the FBM model is employed to obtain the fractal features used for segmentation. The novelty lies in combining the fuzzy-enhancement technique and FBM model, and further illustrating that fractal length-based segmentation provides better results than fractal dimension based segmentation. Experimental results on ultrasound images of carotid artery clearly illustrate that the segmentation outputs obtained from fractal length are superior, and the high qualitative values of DSC, Precision, Recall and F1 score (0.9617, 0.9629, 0.9653 and 0.9641 respectively), together with a low value of APD (1.9316), indicate that the proposed method is comparable to other state-of the-art segmentation techniques. Graphical abstract Summary of proposed technique - overall design flow. PMID- 30302668 TI - Pregnancy-Associated Plasma Protein A (PAPP-A) Concentration in Population of Healthy Young People: Interactions with Tobacco Smoke and Anti-oxidative Status. AB - Pregnancy-associated plasma protein A (PAPP-A) is a high-molecular zinc-binding metalloproteinase that was first detected in the serum of pregnant women. It can also be detected in men and non-pregnant women. Recently, a growing interest in determining the concentration of PAPP-A as a marker of oxidative stress and atherosclerotic processes has been observed. Among the factors that could potentially influence the PAPP-A formation is the exposure to tobacco smoke. Some components of tobacco smoke have an immediate effect on the body and also direct influence on the cardiovascular system. The aim of this study was to evaluate the relation between PAPP-A concentration and either passive or active exposure to tobacco smoke in the population of medicine students (n = 152). The relation between PAPP-A concentration and chosen markers of inflammatory response and anti oxidative processes was analyzed. The samples of serum, urine, and saliva were collected and main nicotine metabolites in urine samples were determined using ELISA technique. Comparison of the PAPP-A concentrations in the study group revealed that in the group of active smokers, the concentration of the protein was significantly higher than in the group of passive smokers (p = .04) and the group of not-exposed students (p = .006). PAPP-A concentration showed significant positive correlation with the values of FRAP and main nicotine metabolites. The evident influence of both active and passive tobacco smoke exposure on PAPP-A levels in the studied population of young people who in general are not included in the group of high-risk cardiovascular incidents, shows how important early prevention of anti-health behaviors is. PMID- 30302669 TI - Phenolic Metabolites Modulate Cardiomyocyte Beating in Response to Isoproterenol. AB - Cardiovascular disease (CVD) is a public health concern, and the third cause of death worldwide. Several epidemiological studies and experimental approaches have demonstrated that consumption of polyphenol-enriched fruits and vegetables can promote cardioprotection. Thus, diet plays a key role in CVD development and/or prevention. Physiological beta-adrenergic stimulation promotes beneficial inotropic effects by increasing heart rate, contractility and relaxation speed of cardiomyocytes. Nevertheless, chronic activation of beta-adrenergic receptors can cause arrhythmias, oxidative stress and cell death. Herein the cardioprotective effect of human metabolites derived from polyphenols present in berries was assessed in cardiomyocytes, in response to chronic beta-adrenergic stimulation, to disclose some of the underlying molecular mechanisms. Ventricular cardiomyocytes derived from neonate rats were treated with three human bioavailable phenolic metabolites found in circulating human plasma, following berries' ingestion (catechol-O-sulphate, pyrogallol-O-sulphate, and 1 methylpyrogallol-O-sulphate). The experimental conditions mimic the physiological concentrations and circulating time of these metabolites in the human plasma (2 h). Cardiomyocytes were then challenged with the beta-adrenergic agonist isoproterenol (ISO) for 24 h. The presence of phenolic metabolites limited ISO induced mitochondrial oxidative stress. Likewise, phenolic metabolites increased cell beating rate and synchronized cardiomyocyte beating population, following prolonged beta-adrenergic receptor activation. Finally, phenolic metabolites also prevented ISO-increased activation of PKA-cAMP pathway, modulating Ca2+ signalling and rescuing cells from an arrhythmogenic Ca2+ transients' phenotype. Unexpected cardioprotective properties of the recently identified human circulating berry-derived polyphenol metabolites were identified. These metabolites modulate cardiomyocyte beating and Ca2+ transients following beta adrenergic prolonged stimulation. PMID- 30302670 TI - From opening the 'black box' to looking behind the curtain: cognition and context in assessor-based judgements. AB - The increasing use of direct observation tools to assess routine performance has resulted in the growing reliance on assessor-based judgements in the workplace. However, we have a limited understanding of how assessors make judgements and formulate ratings in real world contexts. The current research on assessor cognition has largely focused on the cognitive domain but the contextual factors are equally important, and both are closely interconnected. This study aimed to explore the perceived cognitive and contextual factors influencing Mini-CEX assessor judgements in the Emergency Department setting. We used a conceptual framework of assessor-based judgement to develop a sequential mixed methods study. We analysed and integrated survey and focus group results to illustrate self-reported cognitive and contextual factors influencing assessor judgements. We used situated cognition theory as a sensitizing lens to explore the interactions between people and their environment. The major factors highlighted through our mixed methods study were: clarity of the assessment, reliance on and variable approach to overall impression (gestalt), role tension especially when giving constructive feedback, prior knowledge of the trainee and case complexity. We identified prevailing tensions between participants (assessors and trainees), interactions (assessment and feedback) and setting. The two practical implications of our research are the need to broaden assessor training to incorporate both cognitive and contextual domains, and the need to develop a more holistic understanding of assessor-based judgements in real world contexts to better inform future research and development in workplace-based assessments.

AB - Many microorganisms and artificial microswimmers use helical appendages in order to generate locomotion. Though often rotated so as to produce thrust, some species of bacteria such Spiroplasma, Rhodobacter sphaeroides and Spirochetes induce movement by deforming a helical-shaped body. Recently, artificial devices have been created which also generate motion by deforming their helical body in a non-reciprocal way (A. Mourran et al. Adv. Mater. 29, 1604825, 2017). Inspired by these systems, we investigate the transport of a deforming helix within a viscous fluid. Specifically, we consider a swimmer that maintains a helical centreline and a single handedness while changing its helix radius, pitch and wavelength uniformly across the body. We first discuss how a deforming helix can create a non-reciprocal translational and rotational swimming stroke and identify its principle direction of motion. We then determine the leading-order physics for helices with small helix radius before considering the general behaviour for different configuration parameters and how these swimmers can be optimised. Finally, we explore how the presence of walls, gravity, and defects in the centreline allow the helical device to break symmetries, increase its speed, and generate transport in directions not available to helices in bulk fluids. PMID- 30302673 TI - Analysis of Multifloral Bee Pollen Pellets by Advanced Digital Imaging Applied to Functional Food Ingredients. AB - Bee pollen is a hive product, resulting from floral pollen agglutination by worker bees and it is characterized by its excellent bioactive and nutritional composition. Currently, research is focused on bee pollen applications on food industry, because this product has been considered an excellent source of compounds for human nutrition. It is also important in some industries, where color and particle size are important characteristics for production. Due to the granular nature of bee pollen, conventional colorimetry does not allow describing color correctly; thus, digital image analysis is a better alternative. This technique could also allow classifying bee pollen according to its appearance beyond the color. Consequently, the aim of this work was to develop a novel methodology for image data processing to classify bee pollen as ingredient in food industry. Seven color groups in samples were established regarding harvest month and particle size. It was possible to calculate the percentage of each color group in all samples. This methodology also allowed selecting each fraction for different applications in food industry using colorimetry, granulometry and the relationship between both of them. PMID- 30302674 TI - Hematopoietic Cell Transplant (HCT) in the Elderly: Myths, Controversies and Unknowns. AB - The incidence of most hematological malignancies increases with age. Despite the higher incidence of hematological malignancies in the elderly, the geriatric population is poorly represented in the early oncology clinical trials that established the current standards of care. Hematopoietic cell transplant (HCT), either upfront or at relapse, provides a potentially life-prolonging, often curative option for many patients with hematological malignancies and is considered the standard of care, at least for younger patients. Historically, the concern that older adults undergoing HCT may experience higher morbidity and transplant-related complications has limited the use of this potentially curative option to younger adults, particularly in allogeneic (allo-) HCT. There is growing evidence to support the feasibility, tolerability, and relatively similar effectiveness of both autologous and allo-HCT in the geriatric population. In the allo-HCT setting, nonmyeloablative/reduced-intensity conditioning (NMA/RIC) has expanded the spectrum of patients that can be considered for this approach. Overall survival is largely affected by disease stage, performance status, and comorbidities rather than by chronological age per se. Comprehensive geriatric assessment (CGA) is a promising tool that can uncover frequently undocumented vulnerabilities in an elderly transplant-eligible patient. Serial study of CGA throughout the peri-HCT period may help predict the short- and long-term impact of HCT on an older adult's functional status and quality of life. Further research is needed to evaluate whether early intervention to improve such vulnerabilities can improve survival and quality of life of these older patients. PMID- 30302675 TI - ?

PMID- 30302719 TI - Adipocyte proteome and secretome influence inflammatory and hormone pathways in glioma. AB - Gliomas represent the most common primary malignant brain tumors in adults, with an extremely poor prognosis. Among several risk factors, lifestyle was also recently identified as a major risk factor for the development of primary glioma. In the present study, we explore the relationship between obesity and glioma in a cellular model. Thus, we have study the influence of adipocytes secretome on glioma cell line GL261. Using the 3T3-L1 adipocyte cell line, and its conditioned medium (adipokines-enriched medium), we showed that adipocyte-released factors relate with glioma angiogenic, growth, hormones and metabolic behavior by MALDI TOF-MS and proteomic array analysis. In a first view, STI1, hnRNPs and PGK1 are under expressed on CGl. Similarly, both carbonic anhydrase and aldose reductase are even suppressed in glioma cells that grown under adipokines-enriched environment. Contrariwise, RFC1, KIF5C, ANXA2, N-RAP and RACK1 are overexpressed in GL261 cell the in the presence of the adipokines-enriched medium. We further identified the factors that are released by adipocyte cells, and revealed that several pro-inflammatory and angiogenic factors, such as IL-6, IL-11, LIF, PAI-1, TNF-alpha, endocan, HGF, VEGF IGF-I, were secreted to the medium into a high extent, whereas TIMP-1 and SerpinE1 were under expressed on CGl. This study discloses an interesting in vitro model for the study of glioma biology under a "obesity" environment, that can be explored for the understanding of cancer cells biology, for the search of biomarkers, prognostic markers and therapeutic approaches. PMID- 30302721 TI - Improved Glycemic Control with Insulin Glargine 300 U/mL (Toujeo(r)) in Patients with Type 2 Diabetes: Real-World Effectiveness in Switzerland. AB - INTRODUCTION: Insulin glargine 300 U/mL (Gla-300, Toujeo(r)) is a long-acting, once-daily basal insulin with improved-more stable and smoother-pharmacokinetic and pharmacodynamic profiles compared to insulin glargine 100 U/mL (Gla-100) and insulin degludec (IDeg). These properties have been shown to translate into an effective HbA1c reduction with the advantage of a lower risk of hypoglycemia in randomized controlled trials of Gla-300 versus Gla-100. In this study, we assessed the effectiveness and safety of Gla-300 under real-world conditions in Switzerland. METHODS: The prospective, observational, open-label, multicenter study TOP-2 explored the effectiveness of Gla-300 in adult patients with type 2 diabetes (T2D) uncontrolled (HbA1c 7.5-10%) on their previous basal insulin in Germany, Austria, and Switzerland. The primary endpoints were the percentages of patients achieving a fasting plasma glucose (FPG) of <= 6.1 mmol/L after 6 and 12 months. Secondary endpoints included changes in HbA1c, FPG, body weight, and insulin dose as well as hypoglycemia incidence and safety. Here we report the results for the Swiss patient cohort after 12 months of treatment with insulin glargine 300 U/mL. RESULTS: The 62 patients (33 men) had a mean age of 65 years, a mean diabetes duration of 14 years, a mean body mass index (BMI) of 31 kg/m2, and were mainly switched from Gla-100 (44%) to Gla-300. The most common concomitant oral anti-diabetes therapy was metformin (65%). The mean individual HbA1c target chosen by the investigators was 7.4%. After 12 months of therapy, Gla-300 significantly reduced mean HbA1c from 8.2% to 7.6% (p < 0.0001). Likewise, Gla-300 significantly reduced mean FPG from 9.1 mmol/L to 7.4 mmol/L (p < 0.0001). At study end, 32% of patients achieved FPG <= 6.1 mmol/L, 55% achieved FPG <= 7.2 mmol/L , and 57% achieved their individual HbA1c target. Gla-300 was uptitrated to a mean dose of 40 units per day. Symptomatic hypoglycemia incidence after 12 months was low at 9.7% and a rate of 0.23 events per patient year. Body weight remained stable and was not significantly altered during the study. CONCLUSION: Upon switching basaI insulin to Gla-300, overall glucose control significantly improved and glycemic targets were achieved with a low rate of hypoglycemia in T2D patients under real-world conditions in Switzerland.

AB - INTRODUCTION: Early detection of diabetic peripheral neuropathy (DPN) is critical in patients with type 2 diabetes mellitus (T2DM) due to the lack of targeted therapy for DPN. We have investigated the relationship between different stages of diabetic nephropathy and DPN in an attempt to elucidate whether albuminuria can be used as an early warning signal of DPN progression. METHODS: A total of 217 T2DM patients who met the inclusion criteria were recruited from the Department of Endocrinology, Nanfang Hospital between January 2016 and June 2016. These patients were placed in groups based on urinary albumin excretion rate (UAER) and estimated glomerular filtration rate. Nerve conduction studies, the Semmes-Weinstein monofilament test (SWMT) and the vibration perception threshold (VPT) test were conducted. Multiple linear regression analysis, multivariate logistic regression and receiver-operating characteristic (ROC) analysis were performed to investigate the relationship between different stages of diabetic nephropathy and DPN in these patients. RESULTS: Significant differences were observed in the conduction velocity (CV) and amplitude of sensory/motor nerve potential among the T2DM patients at different stages of diabetic nephropathy (all p < 0.05). The UAER and duration of diabetes were found to be independent factors associated with the mean CV and amplitude of sensory/motor nerve potential (all p < 0.05). A disease duration of > 10 years (p = 0.025) and a higher total cholesterol value (p = 0.024) were found to be significantly associated with abnormal SWMT results. A UAER of > 300 mg/24 h (p = 0.007) and a diastolic blood pressure of > 100 mmHg (p = 0.042) were associated with a higher risk for abnormal VPT. A UAER of > 300 mg/24 h (p < 0.001) and a disease duration of > 10 years (p = 0.02) were observed to be significantly correlated with DPN. The ROC analysis showed that the optimal cutoff values of UAER and duration as indicators of DPN were 90.5 mg/24 h and 9.5 years, respectively (both p < 0.001). CONCLUSIONS: The results suggest that diabetic nephropathy is closely associated with the development of DPN in T2DM patients and that UAER and disease duration can be used as warning indicators of DPN progression.

PMID- 30302724 TI - Methamphetamine (MA) Use Induces Specific Changes in LINE-1 Partial Methylation Patterns, Which Are Associated with MA-Induced Paranoia: a Multivariate and Neuronal Network Study. AB - The use of psychoactive substances, including methamphetamine (MA) may cause changes in DNA methylation. The aim of this study was to examine the effects of MA use on long interspersed element-1 (LINE-1) methylation patterns in association with MA-induced paranoia. This study recruited 123 normal controls and 974 MA users, 302 with and 672 without MA-induced paranoia. The Semi Structured Assessment for Drug Dependence and Alcoholism was used to assess demographic and substance use variables. Patterns of LINE-1 methylation were assessed in peripheral blood mononuclear cells and a combined bisulfite restriction analysis (COBRA) was used to estimate overall LINE-1 methylation (mC) while COBRA classified LINE-alleles into four patterns based on the methylation status of two CpG dinucleotides on each strand from 5' to 3', namely two methylated (mCmC) and two unmethylated (uCuC) CpGs and two types of partially methylated loci (mCuC that is 5'm with 3'u and uCmC that is 5'u with 3'm CpGs). MA users showed higher % mCuC and % mCuC + uCmC levels than controls. Use of solvents and opioids, but not cannabis and alcohol dependence, significantly lowered % uCmC levels, while current smoking significantly increased % uCuC levels. MA-induced paranoia was strongly associated with changes in LINE-1 partial methylation patterns (lowered % uCmC), heavy MA use, lower age at onset of MA use, and alcohol dependence. Women who took contraceptives showed significantly lower LINE-1 % mC and % mCmC and higher % uCuC levels than women without contraceptive use and men. The results show that MA-induced changes in LINE-1 partial methylation patterns are associated with MA-induced paranoia and could explain in part the pathophysiology of this type of psychosis. It is argued that MA-induced neuro-oxidative pathways may have altered LINE-1 partial methylation patterns, which in turn may regulate neuro-oxidative and immune pathways, which may increase risk to develop MA-induced paranoia. PMID- 30302720 TI - Oxidative Stress and Inflammation, Key Targets of Atherosclerotic Plaque Progression and Vulnerability: Potential Impact of Physical Activity. AB - Atherosclerosis, a complex cardiovascular disease, is a leading cause of mortality and morbidity worldwide. Oxidative stress and inflammation are both involved in the development of atherosclerotic plaque as they increase the biological processes associated with this pathology, such as endothelial dysfunction and macrophage recruitment and adhesion. Atherosclerotic plaque rupture leading to major ischemic events is the result of vulnerable plaque progression, which is a result of the detrimental effect of oxidative stress and inflammation on risk factors for atherosclerotic plaque rupture, such as intraplaque hemorrhage, neovascularization, and fibrous cap thickness. Thus, both are key targets for primary and secondary interventions. It is well recognized that chronic physical activity attenuates oxidative stress in healthy subjects via the improvement of antioxidant enzyme capacities and inflammation via the enhancement of anti-inflammatory molecules. Moreover, it was recently shown that chronic physical activity could decrease oxidative stress and inflammation in atherosclerotic patients. The aim of this review is to summarize the role of oxidative stress and inflammation in atherosclerosis and the results of therapeutic interventions targeting them in both preclinical and clinical studies. The effects of chronic physical activity on these two key processes are then reviewed in vulnerable atherosclerotic plaques in both coronary and carotid arteries. PMID- 30302725 TI - Differential Methylation of H3K79 Reveals DOT1L Target Genes and Function in the Cerebellum In Vivo. AB - The disruptor of telomeric silencing 1-like (DOT1L) mediates methylation of histone H3 at position lysine 79 (H3K79). Conditional knockout of Dot1l in mouse cerebellar granule cells (Dot1l-cKOAtoh1) led to a smaller external granular layer with fewer precursors of granule neurons. Dot1l-cKOAtoh1 mice had impaired proliferation and differentiation of granular progenitors, which resulted in a smaller cerebellum. Mutant mice showed mild ataxia in motor behavior tests. In contrast, Purkinje cell-specific conditional knockout mice showed no obvious phenotype. Genome-wide transcription analysis of Dot1l-cKOAtoh1 cerebella using microarrays revealed changes in genes that function in cell cycle, cell migration, axon guidance, and metabolism. To identify direct DOT1L target genes, we used genome-wide profiling of H3K79me2 and transcriptional analysis. Analysis of differentially methylated regions (DR) and differentially expressed genes (DE) revealed in total 12 putative DOT1L target genes in Dot1l-cKOAtoh1 affecting signaling (Tnfaip8l3, B3galt5), transcription (Otx1), cell migration and axon guidance (Sema4a, Sema5a, Robo1), cholesterol and lipid metabolism (Lss, Cyp51), cell cycle (Cdkn1a), calcium-dependent cell-adhesion or exocytosis (Pcdh17, Cadps2), and unknown function (Fam174b). Dysregulated expression of these target genes might be implicated in the ataxia phenotype observed in Dot1l-cKOAtoh1.

PMID- 30302728 TI - Faith-Based Groups as a Bridge to the Community for Military Veterans: Preliminary Findings and Lessons Learned in Online Surveying. AB - This report examines responses to a brief online survey, comparing how faith based (n = 27) and non-faith-based (n = 61) organizations engage with Veteran populations as well as the supportive services they provide. Data were analyzed using two-sample z-tests and Chi-squared tests. No significant differences were noted between respondents for self-reported confidence in responding to health care issues/concerns or engagement with Veteran populations. Faith-based respondents were found to provide significantly less mental health, suicide prevention, education/outreach, and other services, while providing significantly more spiritual care. There appears to be ample opportunity for expanding the supportive services provided by faith-based organizations. PMID- 30302729 TI - Our health counts: population-based measures of urban Inuit health determinants, health status, and health care access. AB - OBJECTIVE: Health determinants and outcomes are not well described for the growing population of Inuit living in southern urban areas of Canada despite known and striking health disparities for Inuit living in the north. The objective of this study was to work in partnership with Tungasuvvingat Inuit (TI) to develop population prevalence estimates for key indicators of health, including health determinants, health status outcomes, and health services access for Inuit in Ottawa, Canada. METHODS: We employed community-based respondent driven sampling (RDS) and a comprehensive health assessment survey to collect primary data regarding health determinants, status, and service access. We then linked with datasets held by the Institute for Clinical Evaluative Sciences (ICES), including hospitalization, emergency room, and health screening records. Adjusted population-based prevalence estimates and rates were calculated using custom RDS software. RESULTS: We recruited 341 Inuit adults living in Ottawa. The number of Inuit living, working or accessing health and social services in the City of Ottawa was estimated to be 3361 (95% CI 2309-4959). This population experiences high rates of poverty, unemployment, household crowding, and food insecurity. Prevalence of hypertension (25%; 95% CI 18.1-33.9), chronic obstructive pulmonary disease (6.7%; 95% CI 3.1-10.6), cancer (6.8%; 95% CI 2.7 11.9), and rates of emergency room access were elevated for Inuit in Ottawa compared to the general population. Access to health services was rated fair or poor by 43%. Multiple barriers to health care access were identified. CONCLUSIONS: Urban Inuit experience a heavy burden of adverse health determinants and poor health status outcomes. According to urban Inuit in Ottawa, health services available to Inuit at the time of the study were inadequate.

AB - Mass spectrometry for rapid identification of microorganisms is expanding over the last years because this approach is quick. This methodology provides a decisive interest to fight against bioterrorism as it is applicable whatever the pathogen to be considered and often allows subtyping which may be crucial for confirming a massive and widespread attack with biological agents. Here, we present a methodology based on next-generation proteomics and tandem mass spectrometry for discovering numerous protein biomarkers allowing the discrimination of spores and vegetative cells of Bacillus atrophaeus, a biowarfare simulant. We propose a global quantitative evaluation of the two groups of discriminant biomarkers based on their aggregated normalized spectral abundance factors. PMID- 30302726 TI - Fourth Update on the Iranian National Registry of Primary Immunodeficiencies: Integration of Molecular Diagnosis. AB - BACKGROUND: The number of inherited diseases and the spectrum of clinical manifestations of primary immunodeficiency disorders (PIDs) are ever-expanding. Molecular diagnosis using genomic approaches should be performed for all PID patients since it provides a resource to improve the management and to estimate the prognosis of patients with these rare immune disorders. METHOD: The current update of Iranian PID registry (IPIDR) contains the clinical phenotype of newly registered patients during last 5 years (2013-2018) and the result of molecular diagnosis in patients enrolled for targeted and next-generation sequencing. RESULTS: Considering the newly diagnosed patients (n = 1395), the total number of registered PID patients reached 3056 (1852 male and 1204 female) from 31 medical centers. The predominantly antibody deficiency was the most common subcategory of PID (29.5%). The putative causative genetic defect was identified in 1014 patients (33.1%) and an autosomal recessive pattern was found in 79.3% of these patients. Among the genetically different categories of PID patients, the diagnostic rate was highest in defects in immune dysregulation and lowest in predominantly antibody deficiencies and mutations in the MEFV gene were the most frequent genetic disorder in our cohort. CONCLUSIONS: During a 20-year registration of Iranian PID patients, significant changes have been observed by increasing the awareness of the medical community, national PID network establishment, improving therapeutic facilities, and recently by inclusion of the molecular diagnosis. The current collective study of PID phenotypes and genotypes provides a major source for ethnic surveillance, newborn screening, and genetic consultation for prenatal and preimplantation genetic diagnosis.

AB - In this study, greenhouse experiments were conducted under the condition of different amendment ratios and planting tall fescue (Festuca arundinacea). The amendment ratios of sewage sludge or sludge compost to soil were of 0, 10, 25, and 50% (w/w). The removal rates of PAH, catalase, and dehydrogenase activities of amended soil and accumulation of PAHs by vegetation were detected to investigate the differences of PAH dissipation in sludge-amended and compost amended soils. The initial PAH concentrations in three amended soils increased with the more addition of sludge or compost. After 126-day experiment, maximum PAH removal rates were observed in sludge-amended and compost-amended soils with PAH concentration of about 200 MUg kg-1. And the removal of PAHs showed better efficiencies in compost soil rather than in sludge soil. The more catalase activity and dehydrogenase activity of soil were obtained, respectively, in sludge soil and compost soil. The results indicated that the mechanism of PAH dissipation in two types of amended soils were different. The abundant amount of microorganism dominated PAH dissipation in sludge soils, and PAHs dissipated mainly caused of intense activity of microorganism in compost soils. In addition, PAH accumulation in tall fescue suggested that the transference approach of PAHs was from soil to the roots, and then accumulated in the shoots of tall fescue. It was prone to store up more PAHs in vegetation in the condition of high molar weight of PAHs, more biomass of vegetation, and heavy PAH concentration in soil. PMID- 30302733 TI - The trade-environment nexus in light of governance: a global potential. AB - The theme of paper is to explore the trade-environment relationship and the role of institutions for 117 countries from global standpoint and five regions: Sub Saharan, European, Middle East and North Africa, Asia and Pacific, and Latin America and Caribbean, using the panel data span 2002-2014. By considering the endogeneity problem, to validate the nature of trade-environment nexuses, we applied the GMM first difference model in two steps. Likewise, Dumitrescu-Hurlin panel causality analysis is employed to affirm the causal relationship among the concern variables. The empirical findings of this study validate that the overall trade is significantly good to environment for sample countries (117) of the entire World, Europe, Asia, and Pacific regions. In further assessment, we incorporate interactive terms of institutions with trade, scale effect, and scale technique effect. The estimated results confirm that institution is the persistent instrument for resolving the environmental problems. Furthermore, we find the evidence of inverted u shape EKC in overall selected sample of the World, Sub-Saharan, Europe, Asia, and Pacific regions. In contrast, there is no confirmation of inverted u shape EKC hypothesis in Middle East and North Africa regions. Similarly, no strong evidence of inverted u-shaped EKC hypothesis is observed in Latin-America and Caribbean region. PMID- 30302732 TI - Dysregulation of Sqstm1, mitophagy, and apoptotic genes in chronic exposure to arsenic and high-fat diet (HFD). AB - Arsenic (As) is a toxic and hazardous metalloid. Unfortunately, its presence in drinking water together with wrong nutritional patterns is associated with an increase in the occurrence of metabolic disorders in young people. Degradation of mitochondria is presented by a specific form of autophagy called mitophagy which is an important landmark leading to apoptosis during lipotoxicity. Lipotoxicity and cellular toxicity due to arsenic intake can lead to changes in mitophagy and apoptosis. The protein derived from SQSTM1 gene, also called p62, plays an important role in energy homeostasis in the liver, and it can contribute to the regulation of autophagic responses given its effect on signaling of mTOR, MAPK, and NF-KB. Consequently, changes in Sqstm1, mitophagy (BNIP3), and apoptotic (caspase 3) genes in the livers of NMRI mice were examined with the use of real time RT-PCR Array followed by exposure to an environmentally relevant and negligible cytotoxic concentration of arsenite (50 ppm) in drinking water while being fed with a high-fat diet (HFD) or low-fat diet (LFD) for 20 weeks (LFD-As and HFD-As groups). While LFD-As and HFD groups showed a decrease in BNIP3 expression, a significant increase was observed in the HFD-As group. P62 gene showed downregulation in LFD-As and HFD groups, and upregeneration was observed in the HFD-As group. Caspase 3 showed increased expression as the key factor associated with apoptotic liver cell death in the three groups, with the highest value in HFD-As group. Overall, the changes observed in the expression of Sqstm1, BNIP3, and caspase 3 in this study can be related to the level of liver damage caused by exposure to arsenic and HFD and probably, BNIP3 pro-apoptotic protein is associated with an increased cell death due to HFD and As. PMID- 30302734 TI - Low-frequency electromagnetic treatment of oilfield produced water for reuse in agriculture: effect on water quality, germination, and plant growth. AB - Competing demand for high-quality fresh water for agricultural, industrial, and municipal uses has placed tremendous stress on water resources; irrigating crops with fresh water is expensive and unsustainable. Using unconventional water sources such as oilfield produced water (PW) and treating PW with physical treatment methods such as electromagnetic treatment may overcome water-limitation challenges. A germination experiment was conducted using treated and untreated PW to examine the effect on the germination of iron and clay cowpeas (ICCs) since germination is the stage at which plants are most sensitive to external factors and stresses. The results from the study showed that ICCs germinated when irrigated with higher salinity water that was treated using the electromagnetic technology. A plant growth study was also conducted to assess the effect of electromagnetic treatment of high-salinity PW on the growing ability and crop health of ICCs. A reduction in leaf area expansion rate, the first indicator of salt stress on plants, was observed. After 14 days, plants showed early signs of salt stress such as wilting, lightening in color, and reduction in leaf area. After 28 days, plants watered with higher salinity PW (21,475-42,950 mg/L total dissolved solids) died and plants watered with lower salinity PW (< 21,475 mg/L total dissolved solids) survived but grew smaller than plants irrigated using fresh water. Results from both experiments suggested a potential total dissolved solids limit of ICCs or electromagnetic technology (or both) between 4000 and 10,000 mg/L. The results further suggested that while the electromagnetic technology did not have a strong effect on plant growth, high-salinity water might be treated for reuse in agriculture. PMID- 30302735 TI - Antifibrotics in liver disease: are we getting closer to clinical use? AB - The process of wound healing in response to chronic liver injury leads to the development of liver fibrosis. Regardless of etiology, the profound impact of the degree of liver fibrosis on the prognosis of chronic liver diseases has been well demonstrated. While disease-specific therapy, such as treatments for viral hepatitis, has been shown to reverse liver fibrosis and cirrhosis in both clinical trials and real-life practice, subsets of patients do not demonstrate fibrosis regression. Moreover, where disease-specific therapies are not available, the need for antifibrotics exists. Increased understanding into the pathogenesis of liver fibrosis sets the stage to focus on antifibrotic therapies attempting to: (1) Minimize liver injury and inflammation; (2) Inhibit liver fibrogenesis by enhancing or inhibiting target receptor-ligand interactions or intracellular signaling pathways; and (3) Promote fibrosis resolution. While no antifibrotic therapies are currently available, a number are now being evaluated in clinical trials, and their use is becoming closer to reality for select subsets of patients. PMID- 30302737 TI - Catch the ruler: concurrent validity and test-retest reliability of the ReacStick measures of reaction time and inhibitory executive function in older people. AB - BACKGROUND: Reduced cognitive function, particularly executive function (EF), is associated with an increased risk of falling in older people. We evaluated the utility of the ReacStick test, a clinical test of reaction time, and inhibitory EF developed, for young athletes, for fall-risk assessment in older people. AIMS: To evaluate the psychometric properties of ReacStick measures of reaction time and executive functioning in healthy community-dwelling older people. METHODS: 140 participants (aged 77 +/- 5 years) underwent testing. Two test conditions simple and inhibitory go/no-go-provided measures of reaction time, recognition load (difference in reaction time between conditions), and go/no-go accuracy. Concurrent validity was evaluated against the conventional tests of reaction time and EF (simple hand reaction time, trail-making test, and Stroop colour test). Discriminant ability was determined for fall-risk factors (age, gender, physiological profile assessment, and fall history). Test-retest reliability after 1 week was evaluated in 30 participants. RESULTS: ReacStick reaction time correlated with tests of reaction time and EF, recognition load correlated with inhibitory EF, and go accuracy correlated with reaction time and inhibitory EF. No-go accuracy was not significantly correlated with any of the reaction time and EF tests. Test-retest reliability was good-to-excellent (ICC > 0.6) for all the outcomes. ReacStick reaction time discriminated between groups based on age, recognition load between genders, and no-go accuracy between retrospective fallers and non-fallers. DISCUSSION: An unavoidable time pressure may result in complementary information to the traditional measures. CONCLUSIONS: The ReacStick is a reliable test of reaction time and inhibitory EF in older people and could have value for fall-risk assessment. PMID- 30302736 TI - The Evolution of Estrogen Receptor Signaling in the Progression of Endometriosis to Endometriosis-Associated Ovarian Cancer. AB - To investigate changes in estrogen receptor alpha (ERalpha) signaling during progression of endometriosis to endometriosis-associated ovarian cancer (EAOC) as a driver of malignant transformation. We procured tissue samples of normal endometrium, endometriosis (benign, atypical, concurrent with EAOC), and EAOC. We evaluated expression of a 236-gene signature of estrogen signaling. ANOVA and unsupervised clustering were used to identify gene expression profiles across disease states. These profiles were compared to profiles of estrogen regulation in cancer models from the Gene Expression Omnibus (GEO). Gene Set Enrichment Analysis (GSEA) was performed to determine whether gene expression in EAOC was consistent with ERalpha activity. ANOVA revealed 158 differentially expressed genes (q < 0.05) and unsupervised clustering identified five distinct gene clusters. The estrogen signaling profile of EAOC was not consistent with activated ERalpha in pre-clinical models. Gene set enrichment analysis did not identify signatures of activated ERalpha in EAOC but instead identified expression patterns consistent with loss of ERalpha function and development of endocrine resistance. Gene expression data suggest that ERalpha signaling becomes inactivated throughout the progression of endometriosis to EAOC. The gene expression pattern in EAOC is more consistent with profiles of endocrine resistance. PMID- 30302738 TI - Intracytoplasmic azurophilic inclusions in prolymphocytes.

AB - Hospital readmissions have been used as a prognostic indicator for patients receiving allogeneic hematopoietic cell transplantation (HCT). However, the impact of readmission during early and mid-phase of cord blood transplantation (CBT) on long-term outcomes has not been fully investigated. We retrospectively analyzed 156 adult patients who received single-unit CBT in our institute. Among this cohort, thirteen patients (8%) were readmitted within 30 days after discharge, and 27 (17%) were readmitted within 90 days after discharge. The most common causes for readmission within 30 and 90 days of discharge were infection, chronic graft-versus-host disease, and relapse. Higher cryopreserved cord blood CD34+ cell count was only significantly associated with lower readmission within 90 days after discharge. The probabilities of overall survival were significantly lower in patients readmitted within 90 days after discharge compared with those who were not readmitted within 90 days after discharge in univariate and multivariate analysis. These data suggest that readmission within 90 days after discharge may have a significant impact on long-term mortality after single-unit CBT. PMID- 30302740 TI - Anti-tissue factor pathway inhibitor (TFPI) therapy: a novel approach to the treatment of haemophilia. AB - Novel approaches to the treatment of haemophilia are needed due to the limitations of the current standard of care, factor replacement therapy. Aspirations include lessening the treatment burden and effectively preventing joint damage. Treating haemophilia by restoring thrombin generation may be an effective approach. A promising target for restoring thrombin generation is tissue factor pathway inhibitor (TFPI), a multivalent Kunitz-type serine protease inhibitor that regulates tissue factor-induced coagulation via factor Xa dependent feedback inhibition of the tissue factor-factor VIIa complex. Inhibition of TFPI reverts the coagulation process to a more primitive state evolutionarily, whilst regulation by other natural inhibitors is preserved. An aptamer and three monoclonal antibodies directed against TFPI have been investigated in clinical trials. As well as improving thrombin generation in the range associated with mild haemophilia, anti-TFPI therapies have the advantage of subcutaneous administration. However, the therapeutic window needs to be defined along with the potential for complications due to the novel mechanism of action. This review provides an overview of TFPI, its role in normal coagulation, the rationale for TFPI inhibition, and a summary of anti-TFPI therapies, previously or currently in development. PMID- 30302741 TI - Predicting Substance Use and Deviant Behavior from Prosociality and Sociability in Adolescents. AB - Social competence is commonly considered an important factor that impedes maladaptive development because individuals who lack adequate competence to direct or control their behaviors in social situations are likely to display problems. Despite the belief that social competence may be a multi-dimensional construct, existing research has not explored the unique contributions of its different aspects to development. The present two-wave longitudinal study examined relations of prosociality and sociability, two major aspects of social competence, with problem behaviors in a sample of adolescents. Peer assessment data on prosociality and sociability and self-report data on substance use and deviant behavior were obtained from a sample of adolescents in middle (N = 657, mean age = 13 years) and high (N = 675, mean age = 16 years) schools in China. The results showed that prosociality negatively predicted later problem behaviors, whereas sociability positively predicted later problem behaviors. In addition, gender and grade moderated the associations between sociability and problem behaviors. More specifically, the positive association between sociability and later substance use was significant for boys, but not for girls. Sociability was also more strongly associated with later substance use in middle school than in high school. The results indicate that prosociality and sociability may have different functional meanings in adolescent development and have implications for practical work with adolescents who display problem behaviors. PMID- 30302742 TI - Effect of Long-Term Exercise Training on lncRNAs Expression in the Vascular Injury of Insulin Resistance. AB - LncRNA microarray analysis was applied to investigate the exercise effect on the global differential expressions of lncRNA and mRNA in aorta endothelium in insulin resistance. Twenty-four male C57BL/6 J mice were randomly divided into three groups: control group (n = 8), high-fat diet group (n = 8), and high-fat diet plus exercise training group (n = 8). An lncRNA microarray analysis was applied to investigate the global differential expressions of lncRNA and mRNA in aorta endothelium among three groups and the results were further verified by qPCR. Hypergeometric distribution analysis was applied to reveal the possible signaling. Exercise might alleviate the vascular injury of IR via FR030200 Col3A1, FR402720-Rnd1, and FR030200/FR402720-Rnd3 signalings in cytoskeletal rearrangement pathway; E2F1-FR030200/FR402720-Nnat and FR030200/ FR402720-Fam46a signalings in anti-inflammation pathway. This study identified a panel of dysregulated lncRNAs and mRNAs that might serve as potential biomarkers relevant to the vascular injury in insulin resistance induced by high-fat diet.

AB - This study assessed the role of the processes of change (POC), a construct of the transtheoretical model, in colorectal cancer (CRC) screening among Latinos. Latinos participate in CRC screening less often and are diagnosed with CRC at a later stage than whites. POC items were administered to 344 English- and Spanish speaking Latinos at average risk for CRC who had not had a colonoscopy in the past 5 years and received a colonoscopy referral. POC were measured at three timepoints: following informed consent (T1) at time of referral, 2 weeks prior to scheduled colonoscopy (T2), and 1 month after scheduled colonoscopy (T3). Participants received patient navigation as part of a randomized controlled trial to promote screening colonoscopy. POC scores were examined for changes during the course of the intervention, and logistic regression models assessed the relationship between POC scores and CRC screening adherence. Total POC scores decreased between T1 and T2 (p = 0.03) but were unchanged between T1 and T3. CRC screening adherence was not significantly associated with POC scores or change in POC scores over time. The POC instrument was not found useful for predicting colonoscopy adherence among Latinos in conjunction with patient navigation. Total POC scores did not increase during a patient navigation intervention despite high colonoscopy completion rates. PMID- 30302745 TI - Membrane trafficking and exocytosis are upregulated in port wine stain blood vessels. AB - INTRODUCTION: Port wine stain (PWS) is characterized as a progressive dilatation of immature venule-like vasculatures which result from differentiation-impaired endothelial cells. In this study, we aimed to identify the major biological pathways accounting for the pathogenesis of PWS. METHODS: Sequential windowed acquisition of all theoretical fragment ion mass spectra (SWATH-MS) was used to identify differentially expressed proteins in PWS lesions, followed by confirmative studies with immunohistochemistry, immunoblot and transmission electron microscopy (TEM). RESULTS: 107 out of 299 identified proteins showed differential expressions in PWS lesions as compared to normal skin, mainly involving the functions of biosynthesis, membrane trafficking, cytoskeleton and cell adhesion/migration. The confirmative studies showed that expressions of membrane trafficking/exocytosis related proteins such as VAT1, IQGAP1, HSC70, clathrin, perlecan, spectrin alpha1 and GDIR1 were significantly increased in PWS blood vessels as compared to normal ones; while collagen subtypes 6A1 and 6A3 were decreased in PWS skin. Furthermore, TEM studies showed there is a significant upregulation of extracellular vesicle exocytosis from PWS blood vessels as compared to control. CONCLUSIONS: The biological process of membrane trafficking and exocytosis is enhanced in PWS blood vessels. Our results imply that the extracellular vesicles released by lesional endothelial cells may act as potential intercellular signaling mediators to contribute to the pathogenesis of PWS.

AB - OBJECTIVES: The dorsal interossei of the human foot are arranged so that they abduct the digits around the second digit, while those of non-hominoid anthropoid primates are mostly arranged around the third or fourth digit. This is thought to relate to the medial shift in the functional axis, an essential modification in the evolution of the human foot. However, studies of the arrangement of interosseous muscles are relatively limited and there is some debate about their arrangement in great apes. In particular, some researchers claim that the interossei of chimpanzees are arranged around the second digit, whereas others claim that their foot axis lies on the third digit. MATERIALS AND METHODS: We examined the arrangement of the foot interosseous muscles in ten chimpanzees, one bonobo, and three gorillas. RESULTS: The interossei were arranged around the second digit in two chimpanzees, one bonobo, and one gorilla, whereas the third digit was the axis in the other specimens. DISCUSSIONS: The variation observed suggests that the arrangement of the interosseous muscles of the great apes is in a transitional condition from monkey-type to human-type. Considering that osteological and foot pressure research supports the idea that the foot axis is on the second digit in great apes, modification in the interosseous muscles appears to lag behind modification in the metatarsals and foot motion. PMID- 30302747 TI - Hair cortisol and childhood trauma predict psychological therapy response in depression and anxiety disorders. AB - OBJECTIVE: Around 30-50% of patients with depression and anxiety disorders fail to respond to standard psychological therapy. Given that cortisol affects cognition, patients with altered hypothalamic-pituitary-adrenal (HPA) axis functioning may benefit less from such treatments. To investigate this, reliable pretreatment cortisol measures are needed. METHOD: N = 89 outpatients with depression and anxiety disorders were recruited before undergoing therapy within an Improving Access to Psychological Therapies (IAPT) service. Three-month hair cortisol was determined, and the Childhood Trauma Questionnaire was administered. Patients were classified as responders if they showed significant decreases in depression (>= 6 points on the Patient Health Questionnaire) or anxiety (>= 5 points on the Generalised Anxiety Disorder Scale). RESULTS: Non-responders in terms of depression (57%) had lower pretreatment hair cortisol concentrations (P = 0.041) and reported more physical abuse (P = 0.024), sexual abuse (P = 0.010) and total trauma (P = 0.039) when compared to responders. Non-responders in terms of anxiety (48%) had lower pretreatment hair cortisol (P = 0.027), as well as higher levels of emotional abuse (P = 0.034), physical abuse (P = 0.042) and total trauma (P = 0.048). CONCLUSION: If future research confirms hair cortisol to be a predictor of psychological therapy response, this may prove a useful clinical biomarker which identifies a subgroup requiring more intensive treatment. PMID- 30302748 TI - Countering infanticide: Chimpanzee mothers are sensitive to the relative risks posed by males on differing rank trajectories. AB - OBJECTIVES: Infanticide by males is common in mammals. According to the sexual selection hypothesis, the risk is inversely related to infant age because the older the infant, the less infanticide can shorten lactational amenorrhea; risk is also predicted to increase when an infanticidal male's chance of siring the replacement infant is high. Infanticide occurs in chimpanzees (Pan troglodytes), a species in which male dominance rank predicts paternity skew. Infanticidal male chimpanzees (if low-ranking) are unlikely to kill their own offspring, whereas those who are currently rising in rank, particularly when this rise is dramatic, have an increased likelihood of fathering potential future infants relative to any existing ones. Given that mothers should behave in ways that reduce infanticide risk, we predicted that female chimpanzees, and specifically those with younger, more vulnerable infants, would attempt to adjust the exposure of their infants to potentially infanticidal males. Specifically, mothers of young infants should reduce their association with adult males in general, and to a greater extent, with both low-ranking males and those rising in rank from a position where paternity of current infants was unlikely, to a rank where the probability of siring the next infant is significantly higher. We also investigated the alternative possibility that rather than avoiding all adult males, mothers would increase association with males of stable high rank on the basis that such males could offer protection against infanticide. MATERIALS AND METHODS: We examined data on female association patterns collected from the Budongo Forest, Uganda, during a period encompassing both relative stability in the male hierarchy and a period of instability with a mid-ranking male rising rapidly in rank. RESULTS: Using linear mixed models, we found that mothers reduced their association with the rank-rising male, contingent on infant age, during the period of instability. We also found evidence that females preferentially associated with a potential protector male during the high-risk period. DISCUSSION: Our results support the sexually selected hypothesis for infanticide and demonstrate that female chimpanzees are sensitive to the relative risks posed by adult males. PMID- 30302749 TI - Inhibitory effects of cycloastragenol on abdominal aortic aneurysm and its related mechanisms. AB - BACKGROUND AND PURPOSE: Abdominal aortic aneurysm (AAA) is a degenerative disease affecting human health, but there are no safe and effective medications for AAA therapy. Cycloastragenol (CAG), derived from Astragali Radix, has various pharmacological effects. However, whether CAG can protect against AAA remains elusive. In this study, we investigated whether CAG has an inhibitory effect on AAA and its related mechanism. EXPERIMENTAL APPROACH: The AAA mouse model was induced by incubating the abdominal aorta with elastase. CAG was administered by gavage at different doses beginning on the same day or 14 days after inducing AAA to explore its preventive or therapeutic effects respectively. The preventive effects of CAG on AAA were verified in another AAA mouse model induced by angiotensin II in ApoE-/- mouse. In vitro experiments were implemented on rat vascular smooth muscle cells (VSMCs) stimulated by TNF-alpha. KEY RESULTS: Compared to the control AAA model group, CAG (125 mg.kg-1 body weight day-1 ) reduced the incidence of AAA, the dilatation of aorta and elastin degradation in media in both mouse models of AAA. CAG suppressed the inflammation, oxidation, phenotype switch and apoptosis in TNF-alpha-stimulated VSMCs, ameliorated the expression and activity of MMPs and decreased the activation of the ERK/JNK signalling pathway. CAG also inhibited the degradation of elastin in TNF-alpha stimulated VSMCs. CONCLUSION AND IMPLICATIONS: CAG presents protective effects against AAA through down-regulation of the MAPK signalling pathways and thus attenuates inflammation, oxidation, VSMC phenotype switch and apoptosis and the expression of MMPs as well as increasing elastin biosynthesis.

PMID- 30302752 TI - Introduction of a customised growth chart protocol increased detection of small for gestational age pregnancies in a tertiary Melbourne hospital. AB - BACKGROUND: Growth charts customised for maternal height, weight, ethnicity and parity have been proposed as more effective at detecting infants who are small for gestational age (SGA) than routine screening with symphysio-fundal height measurement alone. Our non-randomised, prospective cohort study assessed antenatal SGA detection rates in a general maternity cohort following the introduction of the Perinatal Institute's Growth Assessment Protocol (GAP) program (consisting of customised growth chart software for plotting symphysio fundal height, staff training and serial auditing). METHODS: The GAP program was implemented into the routine antenatal schedule of 882 women who delivered at The Royal Women's Hospital, Melbourne, during our study period. SGA detection was compared to 936 women from the same team who delivered prior to the intervention. Secondary outcomes assessed were infant gestation at birth and method of delivery, neonatal Apgar scores and admission to the Neonatal Intensive and Special Care nursery (NISC). RESULTS: Identification of SGA infants increased from 21% to 41% with the introduction of the GAP program (OR 2.6, 95% CI 1.3-4.9, P < 0.05). This was not associated with an increase in false-positive rates. Following the introduction of the GAP Program, SGA babies were more likely to be born by vaginal delivery (OR 2.7; 95% CI 1.4-5.1, P < 0.005). There was no overall increase in the induction of labour or caesarean delivery rates. Overall rates of admission to NISC were reduced. CONCLUSIONS: In our increasingly culturally heterogenous society, the use of the GAP program is a safe and potentially more sensitive tool for detecting in utero growth restriction. PMID- 30302753 TI - The steadily growing problem of lentigo maligna and lentigo maligna melanoma in Australia: Population-based data on diagnosis and management. AB - BACKGROUND/OBJECTIVES: There are limited population-based data documenting the incidence and management of lentigo maligna (LM) and invasive lentigo maligna melanoma (LMM). We report the data on occurrence and management of LM and LMM in an Australian population. METHODS: Prospective collection of incidence and clinician-reported management of melanoma in situ (MIS; n = 450, capped) and localised invasive melanoma (n = 3251) notified to the New South Wales Cancer Registry over 12-months in 2006-2007. RESULTS: The estimated annual incidence of all MIS was 27.0 per 100 000 (LM 12.2, non-LM MIS 5.9 and unclassified MIS 9.0). Patients with LM or LMM were on average approximately 10 years older than those with other melanoma subtypes (P < 0.001). The head and neck was the location of 59% of LM, 44% of LMM and <20% of other melanoma subtypes (P < 0.001). The majority of LM and LMM were treated only by specialists. Diagnostic partial biopsies were more frequent for LM and LMM than for other melanoma subtypes, and primary care physicians were more likely than specialists to do a punch partial biopsy than a shave biopsy. The reported median definitive excision margin for LM was 5.0 mm compared with 7.2 mm for non-LM MIS (P = 0.001). CONCLUSIONS: In this Australian population, LM was twice as frequent as other types of MIS. Improved strategies for diagnosis and management are required. PMID- 30302754 TI - Confirmation of BRD4 haploinsufficiency role in Cornelia de Lange-like phenotype and delineation of a 19p13.12p13.11 gene contiguous syndrome. AB - Cornelia de Lange syndrome (CdLS) is a genetically and clinical heterogeneous condition characterized by congenital malformation, intellectual disability, and peculiar dysmorphic features. Recently, BRD4 (19p13.12) was proposed as a new critical gene associated with a mild CdLS because of a similar presentation of the patients carrying point mutations and of its involvement in the NIPBL pathway. Patients harboring a 19p interstitial deletion shared some physical features with BRD4 mutation carriers, which results in a more complex phenotype because of the involvement of several neighboring genes. We report a new 19p deletion in a patient clinically diagnosed as CdLS, partially overlapping with previously published cases with the aim to support the role of BRD4 haploinsufficiency in a CdL-like phenotype and to improve the delineation of 19p13.12p13.11 deletion as a new nonrecurrent gene contiguous syndrome, spanning GIPC1, NOTCH3, BRD4, AKAP8, AKAP8L, CASP14, and EPS15L1 genes. Previously described cases are reviewed, attempting to delineate a genotype-phenotype correlation. PMID- 30302755 TI - No evidence of sibling cooperation in the absence of parental care in Nicrophorus vespilloides. AB - Interactions among siblings fall on a continuum with competition and cooperation at opposite ends of the spectrum. Prior work on the burying beetle Nicrophorus vespilloides suggests that parental care shifts the balance between competition and cooperation by masking a density-dependent shift from cooperation to competition. However, these results should be interpreted with caution because they were based on correlational evidence for an association between larval density at dispersal and mean larval mass at dispersal. Here, we test for a causal effect of the initial density of larvae in a brood on the larvae's subsequent performance in the absence of care. We find no effect of the initial larval density on mean larval mass. Thus, our results provide no evidence for sibling cooperation in the absence of care in this species. However, using larval density at dispersal as a predictor of mean larval mass at dispersal, there was a significant correlation between larval density and mean larval mass. Our study highlights the importance of using experimental designs that exclude confounding effects due to shared environmental conditions that otherwise could be misinterpreted as evidence for sibling cooperation.

PMID- 30302757 TI - Estrogen therapy associated with mechanical vibration improves bone microarchitecture and density in osteopenic female mice. AB - We investigated the effects of estrogen therapy (ET) associated with low intensity and high-frequency mechanical vibration (MV) on bone tissue in osteopenic female mice. Fifty 3-month-old female Swiss mice were ovariectomized (OVX) or sham-operated, and distributed after 4 months into the following groups, with 10 animals per group: Sham; Control, OVX + vehicle solution; MV, OVX + MV; ET, OVX + 17beta-estradiol; and MV + ET, OVX + MV and 17beta-estradiol. Both vehicle solution and 17beta-estradiol (10 MUg kg-1 day-1 ) were injected subcutaneously 7 days per week, and vibration (0.6 g, 60 Hz) was delivered 30 min per day, 5 days per week. Bone mineral density (BMD) and body composition were evaluated by densitometry at baseline and after 60 days of treatment when the animals were euthanized, and their femurs underwent histomorphometric and histochemical analyses. The Control group showed increased weight and fat percentage, while the ET and MV + ET groups showed increased lean mass but decreased fat percentage. At the end of the treatment period, the BMD decreased in Control, remained constant in Sham and MV, and increased in ET and MV + ET. The MV + ET group showed the greatest bone volume compared with Sham (129%), Control (350%), MV (304%) and ET (14%). No differences occurred in cortical thickness. The Control group showed the highest content of mature collagen fibers, while the MV + ET group showed the highest content of immature collagen fibers. In conclusion, ET plus MV was effective in improving bone quality in osteopenic female mice, and this improvement is associated with specific changes in trabecular but not cortical bone. PMID- 30302758 TI - Multiscale behavior analysis and molar behaviorism: An overview. AB - In the context of evolutionary theory, behavior is the interaction between the organism and its environment. Two implications follow: (a) behavior takes time; and (b) behavior is defined by its function. That behavior takes time implies that behavioral units are temporally extended patterns or activities. An activity functions as an integrated whole composed of parts that are themselves smaller scale activities. That behavior is defined by its function implies that behavior functions to change the environment in ways that promote reproductive success. Phylogenetically important events (PIEs) are enhanced or mitigated by activities they induce as a result of natural selection. Induction explains all the phenomena that have traditionally been explained by reinforcement. This multiscale view replaces discrete responses and contiguity with multiscale activities and covariance. A PIE induces operant activity as a result of covariance in the form of a feedback relation between the activity and the PIE. A signal (conditional inducer) induces PIE-induced activities as a result of covariance between the PIE and the signal. In an ontological perspective, behavior is a process, and an activity is a process individual. For example, ontological considerations clarify the status of delay and probability discounting. A true natural science of behavior is possible. PMID- 30302759 TI - Shifting preferences for choice-making opportunities through histories of differential reinforcer quality. AB - Children of both typical and atypical cognitive development tend to prefer contexts in which their behavior results in a choice of reinforcers rather than a single reinforcer, even when the reinforcer accessed is identical across conditions. The origin of this preference has been attributed speculatively to behavioral histories in which choice making tends to be associated with differentially beneficial outcomes. Few studies have evaluated this claim, and those that have, have yielded mixed results. We provided five preschool-aged children experiences in which choice-making and no-choice contexts were differentially associated with higher preference and larger magnitude reinforcers, and we assessed changes in their preference for choice and no-choice contexts in which outcomes were equated. These conditioning experiences resulted in consistent and replicable shifts in child preference, indicating that preference for choice is malleable through experience. PMID- 30302760 TI - High moisture extrusion of lupin protein: influence of extrusion parameters on extruder responses and product properties. AB - BACKGROUND: High moisture extrusion (HME) of lupin protein concentrate and isolate (50:50) mixture was performed by varying the extrusion parameters, such as barrel temperature (138-180 degrees C), water feed (40-68%) and screw speed (400-1800 rpm). The effect of extrusion parameters on extruder responses [die pressure, product temperature, torque and specific mechanical energy (SME)] and product properties [colour, cutting force, cooking yield, microstructure and in vitro protein digestibility (IVPD)] was evaluated. RESULTS: The multiple regression analysis of the results revealed that the water feed had a significant negative linear effect on the extruder responses considered, as well as on colour difference and cutting force of extrudates. Screw speed had a positive linear effect on product temperature, SME and cooking yield. Barrel temperature affected extruder responses and product properties to a lesser extent. Scanning electron microscopy showed that denser microstructure and higher number of fibre layers were created by increasing temperature and screw speed along with decreasing water feed. The results of IVPD of selected extrudates showed that the increase in barrel temperature decreased the IVPD, whereas the increase in water feed resulted in higher IVPD. The screw speed had no significant effect on IVPD. CONCLUSION: The study demonstrates that the use of lupin protein is feasible to produce meat analogues with HME which could enhance the possibilities to meet the growing protein demands for human consumption.

AB - OBJECTIVE: To describe and compare fluoroscopic guidance for placement of wide bore thoracostomy tubes (FGTT) to traditional, blind placement of thoracostomy tubes (BPTT). STUDY DESIGN: Prospective clinical trial. ANIMALS: Twenty client owned dogs. METHODS: Dogs requiring medical management of pleural effusion received a BPTT, whereas dogs undergoing postoperative management of pneumothorax and/or pleural fluid after lateral thoracotomy received an FGTT. Time of placement, accuracy of positioning, radiation exposure, and complications were compared between groups. RESULTS: Initial placement of BPTT took a mean of 168 seconds (range, 89-197), whereas adequate placement was radiographically confirmed at 20 minutes and 38 seconds (range, 7 minutes and 57 seconds to 39 min). Initial placement of FGTT took a mean time of 108 seconds (range, 50-341, P = .17), and adequate placement was confirmed at 125 seconds (range, 50-341, P < .001). Major errors in placement requiring removal and replacement occurred in 2 dogs for BPTT and in none for FGTT. Procedural complications did not differ between groups, and no postoperative complication occurred within the first 12 hours after placement. Radiation entrance surface dose was lower in the BPTT group (P = .004), but stochastic radiation doses did not differ. CONCLUSION: Fluoroscopic guidance of wide-bore thoracostomy tubes accelerated the time to accurate tube placement and alleviated the requirement for removal and replacement in this population. Although use of fluoroscopy increased radiation entrance surface dose, the dose was not clinically significant. CLINICAL SIGNIFICANCE: Fluoroscopic guidance of wide-bore thoracostomy tubes should be considered as an alternative to traditional, blind placement. PMID- 30302762 TI - Prognostic value of noninvasive programmed stimulation in patients with implantable cardioverter defibrillator. AB - BACKGROUND: Implantable cardioverter defibrillator (ICD) offers an opportunity to examine vulnerability to ventricular tachycardia (VT) or ventricular fibrillation (VF) by performing noninvasive programmed ventricular stimulation (NIPS). Whether NIPS can predict VT/VF recurrences has not yet been established. PURPOSE: To examine the predictive value of NIPS for identification of patients with VT/VF recurrences. METHODS: The study group consisted of consecutive 105 ICD recipients included in the prospective NIPS-ICD study (ClinicalTrials ID: NCT02373306) (88 males, age 65 +/- 11 years). The patients underwent NIPS using the protocol up to three premature extrastimuli at 600-500- and 400-ms drive cycle lengths. The endpoint of NIPS was induction of sustained VT or VF or completion of the protocol. RESULTS: VT/VF was induced in 29 (27.6%) patients. During a 12-month follow-up NIPS-inducible patients had significantly more frequently appropriate ICD therapy than noninducible patients (17% vs 4%, P = 0.023). NIPS-induced VT/VF had a sensitivity of 63%, specificity of 75%, positive predictive value of 17%, and negative predictive value of 96% for identification of patients with future VT/VF. Apart from NIPS, age >= 65 years, QRS duration, treatment with angiotensin converting enzyme, history of coronary artery bypass grafting, history of VT/VF prior to NIPS, and prior appropriate ICD therapy were also associated with VT/VF recurrences. Multivariate analysis showed that, together with QRS duration, NIPS result was an independent predictor of future VT/VF. Predictive value of NIPS was significantly higher in ischemic than nonischemic patients. CONCLUSIONS: NIPS result is associated with future VT/VF. Noninducibility at NIPS identifies those patients with high accuracy who will have uneventful follow-up. PMID- 30302763 TI - Investigation into the causes of aspirin resistance in healthy dogs. AB - Antiplatelet effects of acetylsalicylic acid (ASA, aspirin) may be poor in some individuals. Additionally, no method exists for predicting poor ASA response (resistance) in individual dogs. This study's main objective was to determine whether poor ASA response results from pharmacodynamic or pharmacokinetic causes. ASA concentrations causing 50% inhibition of platelet aggregation (in vitro IC50) were determined using whole blood collected from 21 drug-free healthy dogs to evaluate intrinsic sensitivity of platelets to ASA. Dogs were then administered ASA at 4 mg/kg once orally. Percent decrease in platelet aggregation from baseline, and plasma ASA and salicylic acid (SA) concentrations (expressed as AUC values) were measured for up to 3 hr. By 3 hr, 13/21 (62%) dogs showed >50% aggregation inhibition, while 8/21 (38%) dogs showed <50% inhibition. Aggregation inhibition values were negatively correlated with in vitro IC50 values (Rs = 0.49; p = 0.028) and positively correlated with ASA concentrations (Rs = 0.48; p = 0.03). Furthermore, ASA concentrations were strongly negatively correlated (Rs = -0.88; p < 0.001) with SA/ASA concentration ratios, an index of ASA metabolism to SA by esterase enzymes. Multiple linear regression analysis indicated that 59% (p < 0.001) of interindividual variability in aggregation inhibition was explained by in vitro IC50 values (29% of variability) and ASA concentrations (29% of variability). Consequently, poor in vivo ASA response in these dogs resulted from both pharmacodynamic (decreased platelet sensitivity) and pharmacokinetic (lower ASA concentrations) causes. Lower ASA concentrations may be explained by reduced bioavailability associated with higher esterase activities. PMID- 30302764 TI - Vancomycin hemodialysis: Clearance differences between high-flux hemodialysis and on-line hemodiafiltration. AB - The aim of this study was to analyze the differences between vancomycin clearance (Kd) with high-flux hemodialysis (HFHD) and on-line hemodiafiltration (OL-HDF). The OL-HDF therapy combined the diffusion and convective transport of solutes. To compare the Kd, a vancomycin loading dose of 1 g was administered intravenously post-dialysis to 11 chronic and anuric (<100 mL/24 h) hemodialysis patients, undergoing HFHD and post-dilutional OL-HDF in consecutive therapies. Additional doses of 0.5 g were administered after 45 minutes at the end of each dialysis therapy during antibiotic treatment. Blood samples were drawn from arterial and venous lines at the start of hemodialysis sessions and at the first, second, third, and fourth hours. Additional samples were drawn at 15, 30, and 45 minutes after the end of dialysis therapy. Vancomycin plasma concentration, blood urea nitrogen (BUN), creatinine, and beta2 -microglobulin were measured. The patients' hydration status was evaluated by bioimpedance analysis. The mean of vancomycin dialyzer clearance (Kddc ) calculated was 110.8 +/- 15 mL/min with HFHD and 146.8 +/- 13.8 mL/min with OL-HDF (P = 0.025). Significant differences were also obtained for beta2 -microglobulin clearance, Kddc 72.6 +/- 15.4 mL/min with HFHD and 113.4 +/- 24.2 mL/min with OL-HDF (P = 0.012), whereas no differences were found for BUN or creatinine. Additionally, to analyze differences between HFHD and OL-HDF, a variable volume dual pool mathematical model was developed to estimate the body clearance (Kdbc ), extraction mass (Me ), and inter-compartment mass-transfer coefficient (K12 ) of each molecule. A higher vancomycin Kddc with OL-HDF produced by convection improved removal of antibiotic; this can compromise achieving a therapeutic concentration target. We recommended evaluating increased loading doses of vancomycin and avoiding administration during OL-HDF to assure adequate treatment. PMID- 30302765 TI - Chrysin leads to cell death in endometriosis by regulation of endoplasmic reticulum stress and cytosolic calcium level. AB - Chrysin is a natural compound derived from honey, propolis, or passion flowers and has many functional roles, such as antiinflammatory and antiangiogenesis effects. Although endometriosis is a benign gynecological disease, there is a need to identify the pathology and develop a therapy for endometriosis. Elucidating the biological mechanism of chrysin on endometriosis will improve the understanding of endometriosis. In this study, we confirmed the apoptotic effects of chrysin in human endometriotic cells using End1/E6E7 (endocervix-derived endometriotic cells) and VK2/E6E7 (vaginal mucosa-derived epithelial endometriotic cells). The results showed that chrysin suppressed the proliferation of endometriosis and induced programmed cell death through changing the cell cycle proportion and increasing the cytosolic calcium level and generation of reactive oxygen species. In addition, chrysin activated endoplasmic reticulum (ER) stress by stimulating the unfolded protein response proteins, especially the 78-kDa glucose-regulated protein-PRKR-like ER kinase (PERK) eukaryotic translation initiation factor 2alpha (eIF2alpha) pathway in both endometriotic cell lines. Furthermore, chrysin inactivated the intracellular phosphoinositide 3-kinase (PI3K)/protein kinase B (PKB, also known as AKT) signaling pathway in a dose-dependent manner. Collectively, the results of this study indicated that chrysin induced programmed cell death by activating the ER stress response and inactivating the PI3K signaling pathways in human endometriotic cells. PMID- 30302766 TI - Chitosan-glucose Maillard reaction products and their preservative effects on fresh grass carp (Ctenopharyngodon idellus) fillets during cold storage. AB - BACKGROUND: A decreasing freshness occurrs in Ctenopharyngodon (C.) idellus during post-mortem storage. In the present study, chitosan-glucose Maillard reaction products (CG-MRPs) were prepared by heating chitosan and glucose at different reaction temperatures and then used for preserving the freshness and quality of C. idellus fillets during cold storage (4 degrees C). RESULTS: High temperature enhanced the chitosan-glucose Maillard reaction and promoted the accumulation of melanoidins and intermediate compounds. The reducing power of CG MRPs increased with an increasing reaction temperature. CG-MRPs inhibited the microbial growth rate and retarded the oxidation of proteins, lipids and nucleotides in C. idellus fillets by suppressing total bacterial count, total volatile basic nitrogen, thiobarbituric acid reactive substances and K values during cold storage. Furthermore, CG-MRPs prolonged shelf-life. The fillets treated with the CG-MRPs prepared at 120 degrees C showed an especially longer shelf-life (7 days). The preservative effect of CG-MRPs on fillets was the result of antibacterial components (melanoidins, reductone and furfural) in CG-MRPs and a reducing power against the oxidative degradation of proteins, nucleotides and lipids in C. idellus fillets. CONCLUSION: The present study demonstrates that, for C. idellus fillets, treatment with CG-MRPs prepared at 120 degrees C for 40 min could be a feasible approach for maintaining the freshness of C. idellus fillets and prolonging shelf-life during cold storage.

PMID- 30302767 TI - High intensity focused electromagnetic therapy evaluated by magnetic resonance imaging: Safety and efficacy study of a dual tissue effect based non-invasive abdominal body shaping. AB - OBJECTIVES: This study introduces an initial evaluation of a novel High-Intensity Focused Electromagnetic (HIFEM) technology. The primary goal is to quantify any effects the treatments may have on abdominal tissues, as well as to establish hypotheses for future research of this technology. METHODS: Twenty-two patients received four abdominal treatments using the EMSCULPT device (BTL Industries Inc., Boston, MA). Anthropometric evaluations were recorded and digital photographs were taken at baseline, at 2 months, and at 6 months post-treatments. The MRI without contrast determined by vertertebras T12 and S1 (FIESTA and FSPRG sequences) was used to measure dimensions in coronal cross-sectional images of abdominal muscle and fatty tissues, in order to assess any anatomical changes induced by the application. RESULTS: Analysis of the same MRI slices verified by tissue artefacts showed a statistically significant (all P < 0.0001) average 18.6% reduction of adipose tissue thickness, 15.4% increase in rectus abdominis muscle thickness, and 10.4% reduction in rectus abdominus separation (diastasis recti) as measured from the medial border of the muscle 2 months post-treatment. More significant improvements were observed in patients with BMI 18.5-24.9 (classified as "normal"). MRI data from 6-month follow-up suggest the changes can be preserved in longer term. Tape measurements showed on average 3.8 cm subumbilical circumference reduction. The weight of the subjects did not change significantly (average -0.5 lb; P > 0.05). No adverse events were reported. CONCLUSIONS: MRI, considered as a highly precise diagnostic method, revealed simultaneous muscle growth, fat reduction and reduced abdominal separation at 2 months and at 6 months post treatments, unrelated with dieting. Further research should investigate the exact physiological processes which stand behind the tissue changes observed in this study. Lasers Surg. Med. (c) 2018 The Authors.

AB - The purpose of this pilot study was to design and test research instruments to measure qualified intensive care nurses' implicit and explicit attitudes and behavioral intentions toward obese intensive care patients. In previous studies researchers have demonstrated that some health professionals hold negative attitudes toward obese patients; however, little is known about qualified intensive care nurses' attitudes toward these patients. Our cross-sectional pilot study involved Implicit Association Tests, the Anti-fat Attitude questionnaire, an explicit bias scale comprising ratings of explicit beliefs and feelings, assessment of behavioral intentions based on vignettes, and demographic questions. Thirty qualified intensive care nurses from a general intensive care unit in Norway (80% female; age range 31-62 years) completed the study. Nurses reported implicit and explicit preferences for thin over thick patients and found obese patients lazier than normal-weight patients. Measures of behavioral intentions and anti-fat attitudes were reliable. Generally, the nurses intended to help obese patients immediately. Nevertheless, explicit anti-fat attitudes (rho = -0.49) as well as implicit anti-obese stereotypes (rho = -0.40) were negatively correlated with such intentions. Data supported satisfactory face validity, and convergent and discriminant validity within and between implicit and explicit attitudes and stereotypes. The set of research instruments were reliable, valid, and suitable tools to measure qualified intensive care nurses' implicit and explicit attitudes; however, the present findings need to be replicated in a larger-scale study.

AB - Latinos are more likely to experience uncontrolled pain, and institutional death, and are less likely to engage in advance care planning. Efforts to increase access to palliative care must maximize primary palliative care and community based models to meet the ever-growing need in a culturally sensitive and congruent manner. Patient navigator interventions are community-based, culturally tailored models of care that have been successfully implemented to improve disease prevention, early diagnosis, and treatment. We have developed a patient navigation intervention to improve palliative care outcomes for seriously ill Latinos. We describe the protocol for a National Institute of Nursing Research funded randomized controlled trial designed to determine the effectiveness of the manualized patient navigator intervention. We aim to enroll 240 Latino adults with non-cancer, advanced medical illness from both urban and rural clinical sites. Participants will be randomized to the intervention group (five palliative care patient navigator visits plus bilingual educational materials) or control group (usual care plus bilingual educational materials). Outcomes include quality of life (Functional Assessment of Chronic Illness Therapy), advance care planning (Advance Care Planning Engagement survey), pain (Brief Pain Inventory), symptom management (Edmonton Symptom Assessment Scale-revised), hospice utilization, and cost and utilization of healthcare resources. This culturally tailored, evidence based, theory-driven, innovative patient navigation intervention has significant potential to improve palliative care for Latinos, and facilitate health equity in palliative and end-of-life care.

AB - OBJECTIVES: Intravascular photoacoustic (IVPA) imaging is being developed to image atherosclerotic plaques, a leading cause of morbidity and mortality in the United States. However, the safety of this imaging modality, which requires repeated irradiation with short laser pulses, has not yet been investigated. This study has two objectives. First, determine in vitro the limit of cumulative fluence that can be applied to cells before death at IVPA relevant wavelengths. Second, evaluate if high single pulse fluences are a potential cause of cell death during IVPA imaging. MATERIALS AND METHODS: Experiments were conducted using endothelial cells, macrophages, and smooth muscle cells. The cumulative fluence experiments were conducted at 1064 and 1197 nm, using a high pulse repetition frequency laser. Cells were irradiated with a wide range of cumulative fluences and evaluated for cell death. The thresholds for death were compared to the maximum expected clinical cumulative fluence. To evaluate the effect of single pulse fluences, cells were irradiated at 1064, 1210, and 1720 nm. Light was delivered at a range of pulse energies to emulate the fluences that cells would be exposed to during clinical IVPA imaging. RESULTS: At 1064 nm, all three cell types remained viable at cumulative fluences above the maximum expected clinical cumulative fluence, which is calculated based on common IVPA imaging protocols. At 1197 nm, cells were viable near or just below the maximum expected clinical cumulative fluence, with some cell type to cell type variation. All three cell types remained viable after irradiation with high single pulse fluences at all three wavelengths. CONCLUSION: The cumulative fluence experiments indicate that safety considerations are likely to put constraints on the amount of irradiation that can be used in IVPA imaging protocols. However, this study also indicates that it will be possible to use IVPA imaging safely, since cumulative fluences could be reduced by as much as two orders of magnitude below the maximum expected clinical cumulative fluence by varying the imaging protocol, albeit at the expense of image quality. The single pulse fluence experiments indicate that cell death from single pulse fluence is not likely during IVPA imaging. Thus, future studies should focus on heat accumulation as the likely mechanism of tissue damage. Lasers Surg. Med. (c) 2018 Wiley Periodicals, Inc.

AB - BACKGROUND: Beer flavor stability is important to brewers as a result of the increased global demand for beer. Increasing export leads to prolonged periods of transportation and storage and causes fresh flavor deterioration. Therefore, the present study examined the effect of different temperatures in combination with vibrations on beer quality. Beer was exposed to vibrations (50 Hz, 15 m s-2 , simulating transport) at 5, 30 and 45 degrees C for 22, 38 and 90 h and (for half the samples) aged for 60 days at 30 degrees C. RESULTS: The results obtained indicated decreased oxygen concentrations as a result of an elevated temperature and vibrations. There was no effect (P > 0.05) on color and a limited effect of temperature and vibrations on iso-alpha-acids. The parameters temperature and vibrations have a significant influence (P < 0.05) on aldehyde concentrations, namely total aldehydes, and especially '2-methylpropanal', '2 methylbutanal' and 'furfural'. CONCLUSION: The impact of vibrations on the aldehydes concentrations was substantial when subjected to an elevated temperature. Furthermore, a forced aging test of shorter duration than traditional methods might be developed. (c) 2018 Society of Chemical Industry.

AB - Autophagy is a crucial recycling process that is increasingly being recognized as an important factor in cancer initiation, cancer (stem) cell maintenance as well as the development of resistance to cancer therapy in both solid and hematological malignancies. Furthermore, it is being recognized that autophagy also plays a crucial and sometimes opposing role in the complex cancer microenvironment. For instance, autophagy in stromal cells such as fibroblasts contributes to tumorigenesis by generating and supplying nutrients to cancerous cells. Reversely, autophagy in immune cells appears to contribute to tumor localized immune responses and among others regulates antigen presentation to and by immune cells. Autophagy also directly regulates T and natural killer cell activity and is required for mounting T-cell memory responses. Thus, within the tumor microenvironment autophagy has a multifaceted role that, depending on the context, may help drive tumorigenesis or may help to support anticancer immune responses. This multifaceted role should be taken into account when designing autophagy-based cancer therapeutics. In this review, we provide an overview of the diverse facets of autophagy in cancer cells and nonmalignant cells in the cancer microenvironment. Second, we will attempt to integrate and provide a unified view of how these various aspects can be therapeutically exploited for cancer therapy.

AB - Aspergillosis is an infectious, non-contagious fungal disease of clinical importance in flamingo collections. Itraconazole is an antifungal drug commonly used in the treatment and prophylaxis of avian aspergillosis. Studies have shown that dosage regimes in birds vary based on different itraconazole presentation and administration methods. This investigation used a population pharmacokinetic approach to study itraconazole in lesser flamingos. Itraconazole was administered orally at 10 mg/kg to 17 flamingos. A sparse blood sampling was performed on the subjects, and samples were collected at 1, 2, 3, 5, 8, 12, 16, 21, and 24 hr post drug administration. Twelve flamingos were sampled three times, three birds bled twice and two sampled once. Itraconazole in plasma was quantified using high pressure liquid chromatography (HPLC). A one-compartment pharmacokinetic model with first order absorption was fitted to the data using nonlinear mixed effects modeling (NLME) to determine values for population parameters. We identified a long half-life (T1/2) of more than 75 hr and a maximum plasma concentration (CMAX ) of 1.69 ug/ml, which is above the minimal inhibitory concentrations for different aspergillus isolates. We concluded that plasma drug concentrations of itraconazole were maintained in a population of flamingos above 0.5 ug/ml for at least 24 hr after a single oral dose of 10 mg/kg of itraconazole solution.

AB - Hit, Lead & Candidate Discovery A series of 1-(6-methyl-2-substituted phenyl-4 thioxo-4H-1,3-oxazin-5-yl)ethanones (3a-n) were synthesized by the reaction of benzoyl isothiocyanates with active methylene compound acetylacetone in the presence of triethyl amine in a one-pot process. The structures of the products were elucidated by elemental analyses, FT-IR, 1 H NMR, 13 C NMR, and mass spectroscopy. These new 1,3-oxazine derivatives were evaluated for their inhibitory activity against carbonic anhydrase II. Results for in vitro assay revealed that compound 3b having 4-methoxy phenyl moiety was the most potent inhibitor with IC50 value of 0.144 +/- 0.008 MUM. It exhibited higher enzyme inhibitory activity as compared to the standard acetazolamide (IC50 = 0.997 +/- 0.061 MUM). The compounds 3c, 3h, and 3n also displayed superior inhibitory activities compared to the rest of the synthesized oxazine derivatives. The radical scavenging activity of oxazine derivatives was also performed and it was found that compounds showed moderate antioxidant activity. Lipinski rule confirmed the therapeutic potential of the synthesized compounds. Molecular docking studies were also performed to further understand the binding affinity of these compounds with PDBID 1V9E which confirmed that the synthesized derivatives bind in the active binding site of the target protein. Based upon our results, it is proposed that compound 3b may serve as a lead structure to design more potent carbonic anhydrase inhibitors. PMID- 30302775 TI - Pharmacokinetics of levofloxacin after single intravenous, oral and subcutaneous administration to dogs. AB - The pharmacokinetic properties of the fluoroquinolone levofloxacin (LFX) were investigated in six dogs after single intravenous, oral and subcutaneous administration at a dose of 2.5, 5 and 5 mg/kg, respectively. After intravenous administration, distribution was rapid (T1/2dist 0.127 +/- 0.055 hr) and wide as reflected by the volume of distribution of 1.20 +/- 0.13 L/kg. Drug elimination was relatively slow with a total body clearance of 0.11 +/- 0.03 L kg-1 hr-1 and a T1/2 for this process of 7.85 +/- 2.30 hr. After oral and subcutaneous administration, absorption half-life and Tmax were 0.35 and 0.80 hr and 1.82 and 2.82 hr, respectively. The bioavailability was significantly higher (p ? 0.05) after subcutaneous than oral administration (79.90 vs. 60.94%). No statistically significant differences were observed between other pharmacokinetic parameters. Considering the AUC24 hr /MIC and Cmax /MIC ratios obtained, it can be concluded that LFX administered intravenously (2.5 mg/kg), subcutaneously (5 mg/kg) or orally (5 mg/kg) is efficacious against Gram-negative bacteria with MIC values of 0.1 MUg/ml. For Gram-positive bacteria with MIC values of 0.5 MUg/kg, only SC and PO administration at a dosage of 5 mg/kg showed to be efficacious. MIC-based PK/PD analysis by Monte Carlo simulation indicates that the proposed dose regimens of LFX, 5 and 7.5 mg/kg/24 hr by SC route and 10 mg/kg/24 hr by oral route, in dogs may be adequate to recommend as an empirical therapy against S. aureus strains with MIC <= 0.5 MUg/ml and E. coli strains with MIC values <=0.125 MUg/ml. PMID- 30302776 TI - Pharmacokinetics of monoester-diterpenoid alkaloids in myocardial infarction and normal rats after oral administration of Sini decoction by microdialysis combined with liquid chromatography-tandem mass spectrometry. AB - Monoester-diterpenoid alkaloids are the main bioactive components of Sini decoction, which is a well-known traditional Chinese medicine formula for the treatment of myocardial infarction (MI) and heart failure in China. In this work, an ultra-high-performance liquid chromatography-mass spectrometry combined with microdialysis method was successfully established and applied for investigating for the first time comparative plasma pharmacokinetics of three monoester diterpenoid alkaloids (benzoylmesaconitine, benzoylaconitine and benzoylhypacoitine) in normal and MI rats after oral administration of Sini decoction. The statistical results of pharmacokinetic parameters demonstrated that benzoylmesaconitine, benzoylaconitine and benzoylhypacoitine showed lower peak concentration, longer half-life, smaller area under the concentration-time curve, slower clearance, time to peak concentration and mean residence time in MI rats than in normal rats (p < 0.05), which indicated that monoester-diterpenoid alkaloids exhibited lower systemic exposure and slower elimination in the MI rats. The results provided the experimental basis for understanding the metabolic fate and therapeutic effects of Sini decoction. PMID- 30302777 TI - The role of the unfolded protein response in cancer progression: From oncogenesis to chemoresistance. AB - Tumour cells endure both oncogenic and environmental stresses during cancer progression. Transformed cells must meet increased demands for protein and lipid production needed for rapid proliferation and must adapt to exist in an oxygen- and nutrient-deprived environment. To overcome such challenges, cancer cells exploit intrinsic adaptive mechanisms such as the unfolded protein response (UPR). The UPR is a pro-survival mechanism triggered by accumulation of unfolded or misfolded proteins in the endoplasmic reticulum (ER), a condition referred to as ER stress. IRE1, PERK and ATF6 are three ER anchored transmembrane receptors. Upon induction of ER stress, they signal in a coordinated fashion to re-establish ER homoeostasis, thus aiding cell survival. Over the past decade, evidence has emerged supporting a role for the UPR in the establishment and progression of several cancers, including breast cancer, prostate cancer and glioblastoma multiforme. This review discusses our current knowledge of the UPR during oncogenesis, tumour growth, metastasis and chemoresistance. PMID- 30302778 TI - Lip-to-nose flap for nasal plane reconstruction in dogs: A cadaveric and in vivo feasibility study. AB - OBJECTIVE: To describe a local interpolation flap based on the upper lip for the reconstruction of the dorsal aspect of the nasal plane in dogs. STUDY DESIGN: Ex vivo and in vivo case report. ANIMALS: A 2-year-old medium-sized spayed female mixed-breed dog and a canine cadaver of a medium-sized mixed-breed dog. METHODS: A dorsal defect of the nasal plane of uncertain origin in a dog was reconstructed with a unilateral interpolation flap obtained from the caudal upper lip skin and mucosa (lip-to-nose flap). The procedure was first performed in a cadaveric model to assess its feasibility. RESULTS: The lip-to-nose flap allowed the reconstruction of a dorsal nasal plane defect with a satisfactory cosmetic outcome. The incorporation of the labial mucosa guaranteed a complete and uncomplicated wound healing of the flap; a small area of necrosis occurred at the donor site, which resolved in a few days. CONCLUSION: The use of a lip-to-nose flap was feasible in these 2 medium-sized dogs and led to satisfactory cosmetic outcome. CLINICAL SIGNIFICANCE: A lip-to-nose flap may be considered to reconstruct dorsal nasal plane defects in dogs and allows for a cosmetic outcome. PMID- 30302779 TI - Microbial esterases and ester prodrugs: An unlikely marriage for combating antibiotic resistance. AB - The rise of antibiotic resistance necessitates the search for new platforms for drug development. Prodrugs are common tools for overcoming drawbacks typically associated with drug formulation and delivery, with ester prodrugs providing a classic strategy for masking polar alcohol and carboxylic acid functionalities and improving cell permeability. Ester prodrugs are normally designed to have simple ester groups, as they are expected to be cleaved and reactivated by a wide spectrum of cellular esterases. However, a number of pathogenic and commensal microbial esterases have been found to possess significant substrate specificity and can play an unexpected role in drug metabolism. Ester protection can also introduce antimicrobial properties into previously nontoxic drugs through alterations in cell permeability or solubility. Finally, mutation to microbial esterases is a novel mechanism for the development of antibiotic resistance. In this review, we highlight the important pathogenic and xenobiotic functions of microbial esterases and discuss the development and application of ester prodrugs for targeting microbial infections and combating antibiotic resistance. Esterases are often overlooked as therapeutic targets. Yet, with the growing need to develop new antibiotics, a thorough understanding of the specificity and function of microbial esterases and their combined action with ester prodrug antibiotics will support the design of future therapeutics. PMID- 30302780 TI - Doubly robust estimation of the weighted average treatment effect for a target population. AB - The weighted average treatment effect is a causal measure for the comparison of interventions in a specific target population, which may be different from the population where data are sampled from. For instance, when the goal is to introduce a new treatment to a target population, the question is what efficacy (or effectiveness) can be gained by switching patients from a standard of care (control) to this new treatment, for which the average treatment effect for the control estimand can be applied. In this paper, we propose two estimators based on augmented inverse probability weighting to estimate the weighted average treatment effect for a well-defined target population (ie, there exists a predefined target function of covariates that characterizes the population of interest, for example, a function of age to focus on elderly diabetic patients using samples from the US population). The first proposed estimator is doubly robust if the target function is known or can be correctly specified. The second proposed estimator is doubly robust if the target function has a linear dependence on the propensity score, which can be used to estimate the average treatment effect for the treated and the average treatment effect for the control. We demonstrate the properties of the proposed estimators through theoretical proof and simulation studies. We also apply our proposed methods in a comparison of glucagon-like peptide-1 receptor agonists therapy and insulin therapy among patients with type 2 diabetes, using the UK Clinical Practice Research Datalink data. PMID- 30302781 TI - Model averaging for robust extrapolation in evidence synthesis. AB - Extrapolation from a source to a target, eg, from adults to children, is a promising approach to utilize external information when data are sparse. In the context of meta-analyses, one is commonly faced with a small number of studies, whereas potentially relevant additional information may also be available. Here, we describe a simple extrapolation strategy using heavy-tailed mixture priors for effect estimation in meta-analysis, which effectively results in a model averaging technique. The described method is robust in the sense that a potential prior-data conflict, ie, a discrepancy between source and target data, is explicitly anticipated. The aim of this paper is to develop a solution for this particular application to showcase the ease of implementation by providing R code, and to demonstrate the robustness of the general approach in simulations. PMID- 30302782 TI - Defining predictive factors for reproductive output in captive common marmosets (Callithrix jacchus). AB - Common marmosets (Callithrix jacchus) demonstrate variations in reproductive output, not only in terms of total reproductive output during a lifetime but also in litter size per parturition. The present study explores factors, such as parents' litter size, parturition number, maternal body weight at conception and maternal age, which may account for this variation. A retrospective analysis of clinical records of a captive breeding colony was conducted over a 9-year period yielding reproductive summaries of 26 dams and 22 sires producing a total of 115 litters. Dams born from litters of <=2 (N = 20) more often produced litters of <=2, whereas dams born from litters of >2 (N = 6) more often produced litters of >2 (p < 0.05). The dams' maternal body weight at the time of conception had also a significant effect on subsequent litter size. In addition, the chance of triplets was higher after the second parturition. Maternal age, interbirth interval, and season of birth had no effect on litter size. Factors relating to the sire had a negligible effect on the size of the litter. Multivariate statistical modeling revealed that the dams' original litter size, maternal bodyweight at conception and parturition number are determining factors for the number of babies per litter. This study identified factors determining marmoset litter size, some of which (maternal litter size) are novel to this study and were not reported previously. Further exploration of the potential role of maternal litter size as a determinant of the litter sizes produced by marmoset breeders is warranted. PMID- 30302783 TI - Factors underlying suboptimal diagnostic performance in physicians under time pressure. AB - CONTEXT: Time pressure has been implicated in the suboptimal diagnostic performance of doctors and in increases in diagnostic errors. However, the reasons underlying these effects are not clear. The aim of this study was to investigate the influence of time pressure on physicians' diagnostic accuracy and to explore the mediating effects of perceived stress (emotional pathway) and number of plausible diagnostic hypotheses (cognitive pathway) on the proposed relationship. METHODS: We conducted a randomised controlled experiment. A total of 75 senior internal medicine residents completed eight written clinical cases under conditions with (n = 40) or without (n = 35) time pressure. They were then asked to: (i) rate the overall stress experienced, and (ii) write down any alternative hypotheses they had thought of when diagnosing the cases. In a post hoc analysis, a mediation path analysis was performed to test the causal relationships between time pressure, perceived stress and number of alternative diagnoses. RESULTS: Participants who were under time pressure spent less time diagnosing the cases (85.54 seconds versus 181.81 seconds; p< 0.001) and had a lower mean diagnostic accuracy score (0.44 versus 0.53; p = 0.01). In addition, they reported more stress (5.80 versus 4.69; p = 0.01) and generated fewer plausible tentative hypotheses (0.37 versus 0.51; p = 0.01). Two path coefficients were found to be statistically significant; the first path coefficient referred to the relationship between time pressure and perceived stress (standardised beta = 0.25, p = 0.029), and the second negative path coefficient referred to the relationship between time pressure and number of plausible alternative hypotheses (standardised beta = -0.32, p< 0.01). CONCLUSIONS: Time pressure adversely influences physicians' diagnostic accuracy by increasing their stress response and reducing the number of plausible hypotheses as mediators. PMID- 30302785 TI - Corrigendum. PMID- 30302784 TI - Power analysis for multivariable Cox regression models. AB - In power analysis for multivariable Cox regression models, variance of the estimated log-hazard ratio for the treatment effect is usually approximated by inverting the expected null information matrix. Because, in many typical power analysis settings, assumed true values of the hazard ratios are not necessarily close to unity, the accuracy of this approximation is not theoretically guaranteed. To address this problem, the null variance expression in power calculations can be replaced with one of the alternative expressions derived under the assumed true value of the hazard ratio for the treatment effect. This approach is explored analytically and by simulations in the present paper. We consider several alternative variance expressions and compare their performance to that of the traditional null variance expression. Theoretical analysis and simulations demonstrate that, whereas the null variance expression performs well in many nonnull settings, it can also be very inaccurate, substantially underestimating, or overestimating the true variance in a wide range of realistic scenarios, particularly those where the numbers of treated and control subjects are very different and the true hazard ratio is not close to one. The alternative variance expressions have much better theoretical properties, confirmed in simulations. The most accurate of these expressions has a relatively simple form. It is the sum of inverse expected event counts under treatment and under control scaled up by a variance inflation factor. PMID- 30302786 TI - A phase 1 healthy male volunteer single escalating dose study of the pharmacokinetics and pharmacodynamics of risdiplam (RG7916, RO7034067), a SMN2 splicing modifier. AB - AIMS: Risdiplam (RG7916, RO7034067) is an orally administered, centrally and peripherally distributed, survival of motor neuron 2 (SMN2) mRNA splicing modifier for the treatment of spinal muscular atrophy (SMA). The objectives of this entry-into-human study were to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics of risdiplam, and the effect of the strong CYP3A inhibitor itraconazole on the PK of risdiplam in healthy male volunteers. METHODS: Part 1 had a randomized, double-blind, adaptive design with 25 subjects receiving single ascending oral doses of risdiplam (ranging from 0.6 18.0 mg, n = 18) or placebo (n = 7). A Bayesian framework was applied to estimate risdiplam's effect on SMN2 mRNA. The effect of multiple doses of itraconazole on the PK of risdiplam was also assessed using a two-period cross-over design (n = 8). RESULTS: Risdiplam in the fasted or fed state was well tolerated. Risdiplam exhibited linear PK over the dose range with a multi-phasic decline with a mean terminal half-life of 40-69 h. Food had no relevant effect, and itraconazole had only a minor effect on plasma PK indicating a low fraction of risdiplam metabolized by CYP3A. The highest tested dose of 18.0 mg risdiplam led to approximately 41% (95% confidence interval 27-55%) of the estimated maximum increase in SMN2 mRNA. CONCLUSIONS: Risdiplam was well tolerated and proof of mechanism was demonstrated by the intended shift in SMN2 splicing towards full length SMN2 mRNA. Based on these data, Phase 2/3 studies of risdiplam in patients with SMA are now ongoing. PMID- 30302787 TI - What is the state of complexity science in medical education research? AB - CONTEXT: 'Complexity' is fast becoming a 'god term' in medical education, but little is known about how scholars in the field apply complexity science to the exploration of education phenomena. Complexity science presents both opportunities and challenges to those wishing to adopt its approaches in their research, and debates about its application in the field have emerged. However, these debates have tended towards a reductive characterisation of complexity versus simplicity. We argue that a more productive discussion centres on the multiplicity of complexity orientations, with their diverse disciplinary roots, concepts and terminologies. We discuss this multiplicity and use it to explore how medical education researchers have taken up complexity science in prominent journals in the field. METHODS: We synthesised the health sciences and medical education literature based on 46 papers published in the last 18 years (2000 2017) to describe the patterns of use of complexity science in medical education and to consider the consequences of those patterns for our ability to advance scholarly conversations about 'complex' phenomena in our field. RESULTS: We identified four patterns in the use of complexity science in medical education research. Firstly, complexity science is described in a variety of ways. Secondly, multiple approaches to complexity are used in combination in single papers. Thirdly, the type of complexity science used tends to be left implicit. Fourthly, the complexity orientation used is much more commonly located using secondary source citation rather than primary source citation. CONCLUSIONS: The presence of these four patterns begs the question: Do medical education scholars understand that there are multiple legitimate orientations to complexity science, deriving from distinct disciplinary origins, drawing on different metaphors and serving distinct purposes? If we do not understand this, a cascade of potential consequences awaits. We may assume that complexity science is singular in that there is only one way to do it. This assumption may cause us to perceive our way as the 'right' way and to disregard other approaches as illegitimate. However, this perception of illegitimacy may limit our ability to enter into productive dialogue about our complexity science-inspired research. PMID- 30302788 TI - Gaze and the Eye Pupil Adjust to Imagined Size and Distance. AB - Pupillary responses and associated vergence eye movements were monitored during imagery of objects of differing sizes ("large" or "small") from varying distances ("near" or "far"). Objects' imagined size and distance affected oculomotor behavior. Objects visualized as "far" resulted in the larger pupil dilations and smaller visual angle, while small objects imagined "near" were associated with smaller pupils in contrast to relatively larger pupils when imagined as "far" away. Furthermore, near objects resulted in larger visual angle, and particularly, vergence adjustments were observed that were dependent on imagined size and distance of the small objects. The findings are consistent with the idea that imagery emulates perception, also at the embodied level of oculomotor behaviors. PMID- 30302789 TI - Investigation of structural stability and functionality of homodimeric gramicidin towards peptide-based drug: a molecular simulation approach. AB - Increasing death rates due to antibiotic resistance deteriorate the existing treatment measures. Antimicrobial peptides have turned into the emerging cure for multidrug resistance. However, the stability and functionality determine an antimicrobial peptide as a drug. Analyses of the homodimeric beta-helical peptide, gramicidin have suggested the significant role of gramicidin-A, gramicidin-B, and gramicidin-C as antimicrobial compounds, but the structural basis for understanding the stability and functionality is insufficient to resolve multidrug resistance. To identify the best template among gramicidin types as a therapeutic product, we combined a detailed comparative static analysis and dynamic analysis along with conformational free energy and secondary structure prediction. We observed that the high intramolecular interactions and the geometrical features favored gramicidin-A among other types of gramicidin. Our analyses further revealed that the secondary structure of gramicidin-A showed beta sheets with coils along the conformations without any disruption, thereby enhanced its membrane interactions in terms of binding free energy. In conclusion, gramicidin-A has definitely showed enhanced structural stability and functionality; this could be considered the best template for a potential therapeutic product. PMID- 30302790 TI - Upregulation of lincRNA-p21 in thoracic aortic aneurysms is involved in the regulation of proliferation and apoptosis of vascular smooth muscle cells by activating TGF-beta1 signaling pathway. AB - OBJECTIVE: Long intergenic noncoding RNA-p21 (lincRNA-p21) has been proved in the pathogenesis of aortic aneurysms, while its functionality in thoracic aortic aneurysms (TAA) and the mechanism of function remains unclear. Therefore our study aimed to investigate the role of lincRNA-p21 in TAA. METHODS: Aortic media specimens and blood samples were collected from both patients with TAA and healthy controls. Expression of lincRNA-p21 in those tissues was detected by reverse-transcription quantitative polymerase chain reaction (qRT-PCR). Diagnostic values of lincRNA-p21 in aortic media and blood for TAA were evaluated by receiver operating characteristic curve analysis. LincRNA-p21 overexpression human vascular smooth muscle cells (VSMCs) were prepared and the effects of lincRNA-p21 overexpression on cell proliferation and apoptosis were explored by cell counting kit-8 assay and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay, respectively. Expression of lincRNA-p21 and transforming growth factor beta1 (TGF-beta1) in VSMCs with different treatment was detected by qRT-PCR and Western blot analysis, respectively. RESULTS: Expression of lincRNA-p21 in aortic media tissues and blood was significantly upregulated in TAA patients than in healthy controls. Expression of lincRNA-p21 in aortic media and blood can be used to effectively distinguish TAA patients form healthy controls. LincRNA-p21 overexpression inhibited proliferation and promoted apoptosis of VSMCs, while TGF-beta1 inhibitor reduced those effects. LincRNA-p21 overexpression upregulated TGF-beta1 expression, while TGF-beta1 activator showed no significant effects on lincRNA-p21 expression in VSMC. CONCLUSION: LincRNA-p21 participates in TAA by regulating the proliferation and apoptosis of VSMCs through the activation of TGF-beta1 signaling pathway. PMID- 30302791 TI - Hypoxia-induced regulation of mTOR signaling by miR-7 targeting REDD1. AB - Oxygen is an important factor mediating cell growth and survival under physiological and pathological conditions. Therefore, cells have well-regulated response mechanisms in the face of changes in oxygen levels in their environment. A subset of microRNAs (miRNAs) termed the hypoxamir has been suggested to be a critical mediator of the cellular response to hypoxia. Regulated in development and DNA damage response 1 (REDD1) is a negative regulator of mammalian target of rapamycin (mTOR) signaling in the response to cellular stress, and is elevated in many cell types under hypoxia, with consequent inhibition of mTOR signaling. However, the underlying posttranscriptional regulatory mechanism by miRNAs that contribute to this hypoxia-induced reduction in REDD1 expression remain unknown. Therefore, the aim of the current study was to identify the miRNAs participating in the hypoxic cellular response by scanning the 3'-untranslated region (3'-UTR) of REDD1 for potential miRNA-binding sites using a computer algorithm, TargetScan. miR-7 emerged as a novel hypoxamir that regulates REDD1 expression and is involved in mTOR signaling. miR-7 could repress REDD1 expression posttranscriptionally by directly binding with the 3'-UTR. Upon hypoxia, miR-7 expression was downregulated in HeLa cells to consequently derepress REDD1, resulting in inhibition of mTOR signaling. Moreover, overexpression of miR-7 was sufficient to reverse the hypoxia-induced inhibition of mTOR signaling. Therefore, our findings suggest miR-7 as a key regulator of hypoxia-mediated mTOR signaling through modulation of REDD1 expression. These findings contribute new insight into the miRNA-mediated molecular mechanism of the hypoxic response through mTOR signaling, highlighting potential targets for tumor suppression. PMID- 30302792 TI - MicroRNA-21 increases the expression level of occludin through regulating ROCK1 in prevention of intestinal barrier dysfunction. AB - OBJECTIVE: The aim of this study is to investigate the role of molecular mechanism of microRNA (miR)-21 on tight junction (TJ)-proteins and its protective effects on the intestinal barrier. METHODS: TJ proteins and target genes expression were analyzed in miR-21 inhibition and overexpression NCM460 cell lines. To further verify the role of miR-21, the mmu-miR-21 intestinal epithelial conditional knockout (IKO) mice model was established. MiR-21 expression was detected in clinical specimens of acute stercoral obstruction patients. RESULTS: Rho-associated protein kinase 1 (ROCK1) were identified as target genes of miR 21. There is a negative correlation between miR-21 expression level and TJ proteins levels. TJ protein and ROCK1 were significantly decreased in miR-21 IKO mice, which presented intestinal inflammation response and intestinal barrier dysfunction (both P < 0.05). Determination of clinical samples showed consistent results with NCM460 cell line and miR-21 IKO mice. CONCLUSIONS: MiR-21 could be a protective factor of intestinal barrier dysfunction, which promoting the expression of TJ protein by targeting ROCK1 in vivo and in vitro. PMID- 30302793 TI - Adalimumab treatment in Japanese patients with generalized pustular psoriasis: Results of an open-label phase 3 study. AB - A phase 3, multicenter, open-label, 52-week study investigated the efficacy and safety of adalimumab 80 mg at week 0 followed by adalimumab 40 mg every other week (option to escalate to 80 mg when necessary) in Japanese patients with generalized pustular psoriasis (GPP). Adults (aged 15-75 years) with GPP, total skin score (overall erythema area, erythema area with pustules, and edema area) of 3 or more, and erythema with pustules (skin score, >=1) based on the 2014 Japanese Dermatological Association severity index of GPP were enrolled. The primary efficacy end-point was clinical response at week 16 (non-responder imputation), defined as achieving remission (total skin score, 0) or improvement from baseline (reduction of >=1 point from a baseline total skin score of 3 or >=2 points from a baseline total skin score of >=4). Of 10 enrolled patients (mean disease duration, 10.6 years), seven patients, including three with the dose escalated to 80 mg every other week before week 15, achieved clinical response at week 16, and five achieved clinical response at week 52. Mean change from baseline total GPP score was -4.6 at week 16 (n = 8) and -6.0 at week 52 (n = 5); change in total skin score was -3.1 (n = 8) and -4.2 (n = 5), respectively. Nine patients experienced one or more adverse events and three experienced serious adverse events. The most common adverse events were nasopharyngitis, pruritus and hypoalbuminemia. In conclusion, adalimumab was effective and well tolerated for up to 52 weeks in the treatment of Japanese patients with GPP.

PMID- 30302795 TI - Roles for osteocalcin in proliferation and differentiation of spermatogonial cells cocultured with somatic cells. AB - Spermatogonial cells (SCs) are key cells for spermatogenesis. These cells are affected by paracrine signals originated from nearby somatic cells, among them Leydig cells have receptors for osteocalcin, a hormone known for exerting positive roles in the promotion of spermatogenesis. The aim of this study was to evaluate roles for osteocalcin on SCs proliferative and differentiation features after coculture with Leydig cells. SCs and Leydig cells were isolated from neonate NMRI offspring mice and adult NMRI mice, respectively. SCs population were then enriched in a differential attachment technique and assessed for morphological features and identity. Then, SCs were cocultured with Leydig cells and incubated with osteocalcin for 4 weeks. Evaluation of proliferation and differentiation-related factors were surveyed using immunocytochemistry (ICC), Western blot, and quantitative real-time polymerase chain reaction (PCR). Finally, the rate of testosterone release to the culture media was measured at the end of 4th week. Morphological and flow cytometry results showed that the SCs were the population of cells able to form colonies and to express ID4, alpha6-, and beta1-integrin markers, respectively. Leydig cells were also able to express Gprc6alpha as a specific marker for the cells. Incubation of SCs/Leydig coculture with osteocalcin has resulted in an increase in the rate of expressions for differentiation-related markers. Levels of testosterone in the culture media of SCs/Leydig was positively influenced by osteocalcin. It could be concluded that osteocalcin acts as a positive inducer of SCs in coculture with Leydig cells probably through stimulation of testosterone release from Leydig cells and associated signaling. PMID- 30302796 TI - Long noncoding RNA HOTAIRM1 inhibits cell progression by regulating miR-17-5p/ PTEN axis in gastric cancer. AB - OBJECTIVES: This study was conducted to identify the significantly altered long noncoding RNAs (lncRNAs), messenger RNA (mRNA) and pathways in gastric cancer (GC). METHODS: We used microarray analysis to identify differentially expressed lncRNAs and mRNAs, whereas the obviously changed pathways were found by gene set enrichment analysis. The coexpression network of lncRNA and mRNA was constructed by Cytoscape, and their target relationships with miRNAs were predicted by miRcode and TargetScan. qRT-PCR and Western blot were performed to determine the expression levels of mRNAs and proteins in tissues and cell lines. Dual luciferase reporter assay was applied to achieve the determination of the specific target relationships. Cell viability, migration, and apoptosis were detected by MTT assay, wound healing assay and flow cytometry, respectively. Through the xenograft assay, the gastric tumor was implanted into nude mice to investigate the influence of HOTAIRM1 in vivo. RESULTS: HOTAIRM1 and phosphatase and tensin homolog (PTEN) were both downregulated in GC, whereas miR-17-5p was upregulated. Moreover, the PI3K/AKT pathway was found activated in GC. HOTAIRM1 targeted miR-17-5p, whereas PTEN was the downstream target gene of miR-17-5p. HOTAIRM1 suppressed proliferation and migration of GC cell line and induced their apoptosis, whereas miR-17-5p played the opposite role on GC cell line. HOTAIRM1 also postponed tumor growth in vivo and inhibited the PI3K/AKT pathway in GC. CONCLUSIONS: LncRNA HORAIRM1 suppressed the PI3K/AKT pathway in GC and inhibited the progression of GC by serving as a competing endogenous RNA of miR-17-5p, mediating the expression of PTEN. PMID- 30302797 TI - Immunofluorescent labeling of CD20 tumor marker with quantum dots for rapid and quantitative detection of diffuse large B-cell non-Hodgkin's lymphoma. AB - Fluorescent semiconductor quantum dots (QDs) are newfound nanocrystal probes which have been used in bioimaging filed in recent years. The purpose of this study is to evaluate the diagnostic value of specific QDs coupled to rituximab monoclonal antibody against CD20 tumor markers for patients with diffuse large B cell lymphoma (DLBCL). In current study rituximab-conjugated quantum dots (QDs rituximab) were prepared against CD20 tumor markers for detection of CD20 positive cells (human Raji cell line) using flowcytometry. A total of 27 tumor tissue samples were collected from patients with DLBCL and 27 subjects with negative pathological tests as healthy ones, which stained by QD-rituximab. The detection signals were obtained from QDs using fluorescence microscopy. The flowcytometry results demonstrated a remarkable difference in fluorescent intensity and FL2-H + (CD20-positive cells percentage) between two groups. Both factors were significantly higher in Raji in comparison with K562 cell line (P < 0.05). Lot of green fluorescence signals was observed due to the selectively binding of QD-rituximab to CD20 tumor markers which overexpressed in tumor tissues and a few signals observed on the defined healthy ones. Based on these observations the cut-off point was 46.8 dots and the sensitivity, specificity, positive predictive value, and negative predictive value were 100%, 89.5%, 91.3%, and 100%, respectively (LR+, 9.52; LR-, 0). The QD -rituximab could be beneficial as a bioimaging tool with high sensitivity to provide an accurate molecular imaging technique for identifying CD20 tumor markers for early diagnosis of the patients with DLBCL.

PMID- 30302799 TI - Identification of differentially expressed long noncoding RNAs in human knee osteoarthritis. AB - Long noncoding RNAs (lncRNAs) are considered a novel class of regulatory factors in many diseases, but their biological function and the signaling pathway involved in osteoarthritic (OA) remain unknown. To identify the lncRNAs specifically expressed in OA cartilage, the expression of lncRNAs in OA cartilage was measured using an illumina sequencing platform. Furthermore, differentially expressed transcripts of uncertain coding potential (TUCPs) and messenger RNAs (mRNAs) were identified. The colocated target genes and the possible role of lncRNAs as a competing endogenous RNA (ceRNA) were predicted. Based on 19 samples from osteoarthritis patients of knees, 580 significantly dysregulated lncRNAs as well as differently expressed TUCPs and mRNAs were identified. Four differently expressed lncRNAs (SNHG5, ZFAS1, GAS5, and DANCR) involved in OA cartilage were analyzed by protein-protein interactions network and ceRNA regulatory network. Part of our results were consistent with previous studies, and 96 novel differently expressed lncRNAs were identified in OA. These results could expand our knowledge of the OA mechanism. PMID- 30302800 TI - MiR-10a functions as a tumor suppressor in prostate cancer via targeting KDM4A. AB - Deregulation of microRNAs contributes to the abnormal cell growth which is frequently observed in cancer. In the current study, we detected the expression and regulatory relationship between miR-10a and Lysine-specific demethylase 4A (KDM4A) to reveal their function in prostate cancer (PCa) progression. We found that miR-10a levels were significantly decreased in PCa cell lines in comparison with the normal epithelial cell line RWPE-1. Downregulation of miR-10a levels was also observed in tumor tissues from PCa patients compared with the adjacent normal tissues. Enhanced expression of miR-10a inhibited cell proliferation and colony forming capability of PCa cells. In addition, quantitative real-time polymerase chain reaction and Western blot analysis showed a significant decrease of KDM4A in response to miR-10a elevation in PCa cells. Using dual luciferase assay, we confirmed that KDM4A was a target gene for miR-10a. Furthermore, Western blot analysis indicated that miR-10a overexpression inactivated YAP signaling and suppressed transcription of YAP target genes. Additionally, cell growth arrest and colony forming capacity inhibition induced by miR-10a overexpression could be reversed by YAP overexpression in PCa cells. More importantly, miR-10a mimics inhibited PC-3 tumor growth in nude mice accompanied with a remarkable reduction of KDM4A and YAP expression. In conclusion, our results uncovered a tumor suppressor role of miR-10a in PCa via negative regulation of KDM4A and its downstream Hippo-YAP pathway. PMID- 30302801 TI - MiR-143-3p suppresses cell proliferation, migration, and invasion by targeting Melanoma-Associated Antigen A9 in laryngeal squamous cell carcinoma. AB - Previously we found that melanoma-associated antigen-A9 (MAGE-A9) was a significantly upregulated biomarker in laryngeal squamous cell carcinoma (LSCC). A high expression of MAGE-A9 indicates an unfavorable survival outcome, and the MAGE-A9 expression level is an independent prognostic factor of LSCC. To explore the mechanism of MAGE-A9 upregulation, several predicted regulatory microRNAs were screened and validated in LSCC cells. In the current study, we found that miR-143-3p (MAGE-A9 related miRNAs) expression levels correlated negatively with the MAGE-A9 protein expression in LSCC tissues. Dual-luciferase reporter assays and Western blot analysis revealed MAGE-A9 to be a direct target of miR-143-3p. Furthermore, a series of in vitro gain- and loss-of-function assays revealed that miR-143-3p inhibited LSCC cell proliferation, migration, and invasion. Also, miR 143-3p suppressed LSCC tumorigenesis in vivo. These effects were clinically relevant, as a lower expression of miR-143-3p occurred in severer clinical stages and represented poor overall survival in patients with LSCC. Taken together, these results suggest that downregulation of miR-143-3p contributes to tumor progression through upregulation of MAGE-A9. The expression level of these two key molecules maintained LSCC progression, thus, highlighting the potential of miR-143-3p as a therapeutic target for human LSCC.

PMID- 30302803 TI - A comparison of prenatal muscle transcriptome and proteome profiles between pigs with divergent growth phenotypes. AB - The growth of pigs is an important economic trait that involves multiple genes and coordinated regulatory mechanisms. The growth rate and potential of skeletal muscles are largely decided by embryonic myofiber development. Tibetan pig (TP) that is a mini-type breed has a divergent phenotype in growth rate and adult body weight with Wujin pig (WJ) and large White pig (LW). In the current study, the transcriptome (using RNA-seq) and proteome (using the isobaric tag for relative and absolute quantification [iTRAQ]) data from the prenatal muscle tissues were analyzed to identify the genes related to postnatal growth rate and growth potential in pigs. In the RNA-seq experiment, 19 626 genes were detected in the embryonic muscle tissues, and 3626 unique differentially expressed genes (DEGs) were identified in TP in comparison to that in LW and WJ. In the iTRAQ experiment, 2474 proteins were detected, and 735 unique differentially expressed proteins (DEPs) were identified in TP in comparison to that in LW and WJ. Combining the DEGs and DEPs, 209 genes were found to be differentially expressed, consistently at both the messenger RNA and protein levels, between TP and the other two breeds; these are mainly involved in 2-oxocarboxylic acid metabolism, citrate cycle, and biosynthesis of amino acids. Of these, 20 genes that were related to myoblast differentiation and muscle fiber formation might have important roles in determining the postnatal growth rate and potential body weight in pigs. Our results provide new candidate genes and insights into the molecular mechanisms involved muscle growth traits in pigs. PMID- 30302804 TI - Novel putative drugs and key initiating genes for neurodegenerative disease determined using network-based genetic integrative analysis. AB - Understanding the genetic causes of neurodegenerative disease (ND) can be useful for their prevention and treatment. Among the genetic variations responsible for ND, heritable germline variants have been discovered in genome-wide association studies (GWAS), and nonheritable somatic mutations have been discovered in sequencing projects. Distinguishing the important initiating genes in ND and comparing the importance of heritable and nonheritable genetic variants for treating ND are important challenges. In this study, we analysed GWAS results, somatic mutations and drug targets of ND from large databanks by performing directed network-based analysis considering a randomised network hypothesis testing procedure. A disease-associated biological network was created in the context of the functional interactome, and the nonrandom topological characteristics of directed-edge classes were interpreted. Hierarchical network analysis indicated that drug targets tend to lie upstream of somatic mutations and germline variants. Furthermore, using directed path length information and biological explanations, we provide information on the most important genes in these created node classes and their associated drugs. Finally, we identified nine germline variants overlapping with drug targets for ND, seven somatic mutations close to drug targets from the hierarchical network analysis and six crucial genes in controlling other genes from the network analysis. Based on these findings, some drugs have been proposed for treating ND via drug repurposing. Our results provide new insights into the therapeutic actionability of GWAS results and somatic mutations for ND. The interesting properties of each node class and the existing relationships between them can broaden our knowledge of ND. PMID- 30302805 TI - Identification of potential drugs targeting L,L-diaminopimelate aminotransferase of Chlamydia trachomatis: An integrative pharmacoinformatics approach. AB - Chlamydia trachomatis (C.t) is a gram-negative obligate intracellular bacteria, which is a major causative of infectious blindness and sexually transmitted diseases. A surge in multidrug resistance among chlamydial species has posed a challenge to adopt alternative drug targeting strategies. Recently, in C.t, L,L diaminopimelate aminotransferase (CtDAP-AT) is proven to be a potential drug target due its essential role in cell survival and host nonspecificity. Hence, in this study, a multilevel precision-based virtual screening of CtDAP-AT was performed to identify potential inhibitors, wherein, an integrative stringent scoring and filtration were performed by coupling, glide docking score, binding free energy, ADMET (absorption, distribution, metabolism, and excretion, toxicity) prediction, density functional theory (quantum mechanics), and molecular dynamics simulation (molecular mechanics). On cumulative analysis, NSC_5485 (1,3-bis((7-chloro-4-quinolinyl)amino)-2-propanol) was found to be the most potential lead, as it showed higher order significance in terms of binding affinity, bonded interactions, favorable ADMET, chemical reactivity, and greater stabilization during complex formation. This is the first report on prioritization of small molecules from National Cancer Institute (NCI) and Maybridge data sets (341 519 compounds) towards targeting CtDAP-AT. Thus, the proposed compound shall aid in effective combating of a broad spectrum of C.t infections as it surpassed all the levels of prioritization. PMID- 30302806 TI - LncRNA MNX1-AS1 promotes the progression of cervical cancer through activating MAPK pathway. AB - Long noncoding RNAs (lncRNAs) have been discovered as significant regulators in a wide range of human cancers. Among them, lncRNA MNX1-AS1 has been proved to be an oncogene in ovarian cancer and glioblastoma. However, the regulatory mechanism of MNX1-AS1 in cervical cancer remains to be understood. Therefore, this study planned to explore the role of MNX1-AS1 in cervical cancer. In the beginning, we found that the expression of MNX1-AS1 was obviously upregulated in cervical cancer tissues and cell lines. Kaplan-Meier survival analysis revealed that patients with higher MNX1-AS1 expression level suffered from shorter overall survival time than those with lower MNX1-AS1 level. Moreover, by loss-of-function and gain-of-function assay, the effect of MNX1-AS1 on cell proliferation and apoptosis was examined on cellular level. Results showed that the proliferation of Hela cells was significantly inhibited and apoptosis enhanced by the transfection of shMNX1-AS1, while overexpressing MNX1-AS1 in E6E7 cells presented the contrary results. As for mechanism investigation, it was demonstrated that overexpression of MNX1-AS1 significantly improved the expression of p-ERK1/2 and p-JNK. And the effects of MNX1-AS1 on cell proliferation and apoptosis would be diminished after inactivating the phosphorylation of either ERK or JNK. Taken together, it was identified that MNX1-AS1 promoted proliferation and inhibited apoptosis of cervical cancer cells through MAPK pathway. PMID- 30302807 TI - MiR-216b inhibits osteosarcoma cell proliferation, migration, and invasion by targeting Forkhead Box M1. AB - Osteosarcoma (OS) is considered the most common type of primary malignant bone tumor, which has a high rate of mortality in children and adolescents. However, the current treatment methods for OS are ineffective. Therefore, there is an urgent requirement to identify the critical targets. This study aimed to identify the roles and significance of microRNA-216b (miR-216b) in OS. To explore the cellular and molecular functions of miR-216b and Forkhead Box M1 (FoxM1) in OS, the expression of miR-216b and FoxM1 at the transcriptional level was measured using quantitative real-time PCR (qRT-PCR). Wound healing assay, 3-[4,5 dimethylthiazol-2-yl]-2,5 diphenyltetrazolium bromide assay (MTT) assay, flow cytometry, and transwell invasion assay were conducted to study the function of miR-216b and FoxM1 in OS cells. Dual luciferase reporter assay was performed to identify the relationships between miR-216b and FoxM1. qRT-PCR results revealed that miR-216b expression was significantly downregulated, and FoxM1 was observed to be significantly upregulated in human OS cell lines (MG-63) and tissues. MTT data showed that upregulation of miR-216b expression led to cell growth inhibition in MG-63 cells. The results of the invasion assay and wound healing assay illustrated that miR-216b upregulation or FoxM1 downregulation could inhibit the invasion and migration in MG-63 cells. In vivo, the tumor volume was significantly decreased by miR-194 mimic treatment compared with the control group. Furthermore, the results of the luciferase assay indicated that FoxM1 is a direct target of miR-216b. These findings may provide novel insights into the molecular mechanism of miR-216b and FoxM1 in the progression of OS, and suggested that miR-216b may serve as a potential tumor inhibitor of OS by targeting FoxM1. PMID- 30302808 TI - Embryonic poly(A)-binding protein is differently expressed and interacts with the messenger RNAs in the mouse oocytes and early embryos. AB - The embryonic poly(A)-binding protein (EPAB) functions in the translational regulation of the maternal messenger RNAs (mRNAs) required during oocyte maturation, fertilization, and early embryo development. Since there is no antibody specific to mammalian EPAB protein, all studies related to the Epab gene could be performed at the mRNA levels except for the investigations in the Xenopus. In this study, we have produced an EPAB-specific antibody. When we examined its expressional distribution in the mouse gonadal and somatic tissues, the EPAB protein was found to be expressed only in the mouse ovary and testis tissues, but it is undetectable level in the somatic tissues including stomach, liver, heart, small intestine, and kidney. Additionally, the spatial and temporal expression patterns of the EPAB and poly(A)-binding protein cytoplasmic 1 (PABPC1) proteins were analyzed in the mouse germinal vesicle (GV) and metaphase II (MII) oocytes, one-cell, and two-cell embryos. While EPAB expression gradually decreased from GV oocytes to two-cell embryos, the PABPC1 protein level progressively increased from GV oocytes to one-cell embryos and remarkably declined in the two-cell embryos ( P < 0.05). We have also described herein that the EPAB protein interacted with Epab, Pabpc1, Ccnb1, Gdf9, and Bmp15 mRNAs dependent upon the developmental stages of the mouse oocytes and early embryos. As a result, we have first produced an EPAB-specific antibody and characterized its expression patterns and interacting mRNAs in the mouse oocytes and early embryos. The findings suggest that EPAB in cooperation with PABPC1 implicate in the translational control of maternal mRNAs during oogenesis and early embryo development. PMID- 30302809 TI - Ablation alleviates atrial fibrillation by regulating the signaling pathways of endothelial nitric oxide synthase/nitric oxide via miR-155-5p and miR-24-3p. AB - BACKGROUND: This study aimed to identify the microRNAs implicated in atrial fibrillation (AF) to investigate the molecular mechanisms underlying the role of microRNAs in ablation-based AF treatment. METHODS: Real-time polymerase chain reaction (PCR) and microRNA microarrays were utilized to measure the profiles of microRNA expression in AF to identify differentially expressed microRNAs. Enzyme linked immunosorbent assay, real-time PCR, Western blot analysis, and immunohistochemistry assays were also performed to investigate the regulatory relationships among various factors implicated in AF. Finally, bioinformatic tools and luciferase assays were used to confirm the roles of miR-155-5p, miR-24 3p, endothelial nitric oxide synthase (eNOS), and nitric oxide (NO) in the pathogenesis of AF. RESULTS: We demonstrated that the levels of miR-155-5p and miR-24-3p were greatly reduced in postablation AF patients compared with those AF patients not treated by ablation. Furthermore, the NO level in the AF+ group was much lower than that of the AF- group. Finally, in a swine model of AF, evident upregulation of miR-155-5p and miR-24-3p was found in AF pigs, whereas the ablation treatment reduced the levels of miR-155-5p and miR-24-3p in AF pigs. On contrary, as targets of miR-155-5p and miR-24-3p, the levels of eNOS and NO increased when the expression of miR-155-5p and miR-24-3p decreased. CONCLUSION: MiR-155-5p and miR-24-3p are involved in the pathogenesis of AF via regulating the expression of eNOS and the production of NO. In addition, ablation treatment helps the recovery from AF by reducing the expression of miR-155-5p and miR-24 3p. PMID- 30302810 TI - Photodynamic treatment with anionic nanoclays containing curcumin on human triple negative breast cancer cells: Cellular and biochemical studies. AB - Photodynamic treatment is a minimally invasive and clinically approved procedure for eliminating selected malignant cells with activation of a photosensitizer agent at a specific light. Little is known, however, about the phototoxic properties of curcumin, as a natural phenolic compound, against different types of cancers. It is generally accepted that cellular damage occurs during photo treatment. There is a limitation in using of curcumin as a drug due to its low solubility, but nanoparticles such as anionic nanoclays or layered double hydroxide (LDH) could overcome it. The aim of this study was to investigate cellular responses to curcumin-LDH nanoparticles after photodynamic treatment of MDA-MB-231 human breast cancer cells. For this purpose, the MDA-MB-231 human breast cancer cell line treated with curcumin-LDH nanoparticle and then irradiated (photodynamic treatment). After irradiation, lactate dehydrogenase assay, clonogenic cell survival, cell death mechanisms such as autophagy and apoptosis were determined. Cell cycle distribution after photodynamic therapy (PDT) and also intracellular reactive oxygen species (ROS) generation were measured. The result showed that curcumin-LDH-PDT has a cytotoxic and antiprolifrative effect on MDA-MB-231 human breast cancer cells. Curcumin-LDH-PDT induced autophagy, apoptosis, and G0/G1 cell cycle arrest in human breast cancer cell line. Intracellular ROS increased in MDA-MB-231 cancer cell line after treatment with curcumin-LDH along with irradiation. The results suggest that curcumin-LDH nanoparticle could be considered as a novel approach in the photodynamic treatment of breast cancer. PMID- 30302811 TI - Microporous cellulosic scaffold as a spheroid culture system modulates chemotherapeutic responses and stemness in hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) treatments are evaluated by two-dimensional (2D) in vitro culture systems, despite their limited ability to predict drug efficacy. The three-dimensional (3D) microporous scaffold provides the possibility of generating more reliable preclinical models to increase the efficacy of cancer treatments. The physical properties of a microporous cellulosic scaffold were evaluated. The cellulosic scaffold was biocompatible and had a highly porous network with appropriate pore size, swelling rate, and stiffness of cancer cell cultures. Cellulosic scaffolds were compared with 2D polystyrene for the culture of HepG2 and Huh7 human HCC cells. Cellulosic scaffolds promoted tumor spheroid formation. Cells cultured on scaffolds were more resistant to chemotherapy drugs and showed upregulation of EpCAM and Oct4. The migration ability of HCC cells cultured on scaffolds was significantly greater than that of cells grown in 2D cultures as evidenced by the downregulation of E-cadherin. In addition, the proportion of CD44+/CD133+ HCC cancer stem cells (CSCs) was significantly greater in cells cultured on scaffolds than in those grown in 2D cultures. These findings suggest that cellulosic scaffolds effectively mimic the in vivo tumor behavior and may serve as a platform for the study of anticancer therapeutics and liver CSCs. PMID- 30302812 TI - Comparing the efficacy of pain managements after total hip arthroplasty: A network meta-analysis. AB - The aim of our current study is to compare efficiency of various interventions implemented for pain management after total hip arthroplasty (THA). PubMed and EMBASE were searched for randomized clinical trials (RCTs) reporting the pain scales for evaluate the efficacy of pain control after THA including at least one pair of direct control groups. Pain scale values and the associated 95% credible interval (CrI) were used to describe efficacy. Surface under the cumulative ranking curve (SUCRA) of each means of pain control was calculated to compare the relative ranking of different interventions. Thirty-five eligible literatures were involved in data analysis. The interventions for postoperative pain management we examined were psoas compartment block (PCB), posterior nerve block (PNB), fascia iliaca block (FIB), periarticular injection (PAI), femoral nerve block (FNB), lumbar plexus block (LPB), spinal anesthesia (SA), epidural analgesia (EPI), intrathecal morphine (IA), intravenous patient-controlled analgesia (IV-PCA), patient-controlled analgesia (PCA), onsteroidal anti inflammatory drug (NSAID), local infiltration analgaesia (LIA), and reverse LIA (rLIA). In 0 to 6 hours analysis, patients under SA were found to have significantly lower pain score and SA was ranked the best. In 6 to 12 hours analysis, SA was found to be significantly more effective than other interventions and its SUCRA was the highest. No intervention showed a significant effect on reducing pain score for 12 to 24 hours and 24 to 48 hours after THA. SA is the best intervention to reduce THA postoperative pain in the first 24 hours. LPB is a better choice to reduce pain 12 to 48 hours after THA. PMID- 30302813 TI - miR-17-5p promotes proliferation and epithelial-mesenchymal transition in human osteosarcoma cells by targeting SRC kinase signaling inhibitor 1. AB - MicroRNA-17-5p (miR-17-5p) and epithelial-mesenchymal transition (EMT) have been reported to participate in the development and progression of multiple cancers. However, the relationship between the miR-17-5p and EMT in osteosarcoma (OS) is still poorly understood. This study was to investigate the effects of the miR-17 5p and its potential mechanism in regulating proliferation, apoptosis, and EMT of human OS. Quantitative real-time PCR was used to detect the miR-17-5p and SRC kinase signaling inhibitor 1 (SRCIN1) messenger RNA expression in OS specimens and cell lines. After transfection with miR-17-5p inhibitors, proliferation, apoptosis, migration, and invasion of OS cells were assessed by using the Cell Counting Kit-8, the annexin V-FITC apoptosis, wound-healing, and transwell assays. The SRCIN1 was validated as a target of the miR-17-5p through bioinformatics algorithms and luciferase reporter assay. Moreover, the expression of EMT markers, E-cadherin, N-cadherin, and Snail was identified by the Western blot analysis. MiR-17-5p was significantly upregulated in OS tumor samples and cell lines. It inhibited proliferation and EMT, and promoted apoptosis in OS. The SRCIN1 was identified as a direct target of the miR-17-5p. Silenced miR-17-5p could change the expression of EMT markers, such as upregulating the expression of E-cadherin, and downregulating the expression of N-cadherin and Snail through targeting the antioncogenic SRCIN1. These findings suggest that the miR-17-5p promotes cell proliferation, and EMT in human OS by directly targeting the SRCIN1, and reveal a branch of the miR-17-5p/SRCIN1/EMT signaling pathway involved in the progression of OS. PMID- 30302814 TI - Platelet-neutrophil interaction aggravates vascular inflammation and promotes the progression of atherosclerosis by activating the TLR4/NF-kappaB pathway. AB - Platelet-neutrophil interaction is well known for its role in inflammatory diseases; however, its biological role in atherosclerosis (AS) progression remains unclear. Human peripheral blood neutrophils were obtained to compare toll like receptor 4 (TLR4), tumor necrosis factor alpha (TNF-alpha), interleukin (IL) 1beta and myeloid-related proteins 8/14 (Mrp8/14) levels in 22 AS patients with those in 18 healthy controls using quantitative real-time polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA). Meanwhile, mouse marrow neutrophils subjected to different treatment were collected for the ELISA assay, cell apoptosis, and Western blot analysis. Normal diet or high-fat diet ApoE-/- mice with or without administration of Mrp8/14 antagonist paquinimod were used for plasma collection to measure total cholesterol, triglycerides, low density lipoprotein cholesterol and high-density lipoprotein cholesterol, TNF alpha, IL-1beta, Mrp8/14, TLR4, and nuclear factor (NF)-kappaB p65 levels. The results showed that Mrp8/14 and TLR4-mediated inflammatory pathway was activated in neutrophils of AS patients. In vitro experiments demonstrated that platelet neutrophil interaction promoted the Mrp8/14 release and inhibited neutrophil apoptosis via P-selectin. Furthermore, platelet-neutrophil interaction upregulated TLR4/myeloid differentiation factor 88/NF-kappaB pathway. Conversely, Mrp8/14/TLR4/NF-kappaB interference alleviated AS progression. In conclusion, Mrp8/14/TLR4/NF-kappaB activated by platelet-neutrophil interaction is an important inflammatory signaling pathway for AS pathogenesis.

AB - The Mediterranean fruit fly, Ceratitis capitata (Wiedemann, 1824; Diptera: Tephritidae), is a polyphagous pest in horticulture, mainly targeting Citrus fruits. Natural essential and fixed oils are currently under investigation for their broad-spectrum in pest control. To gain better knowledge about medfly behavior and biochemistry, we examined with behavioral and biochemical assays, the effects on C. capitata from six natural fixed oils obtained from vegetable (five) or animal (one) matrices using the eco-friendly supercritical CO 2 extraction. Oils were obtained at 250/300 bar and 40 degrees C from the seeds of Laurus nobilis and Citrus paradisi, the fruits of Myristica fragrans and Pistacia terebinthus, wheat germ, and mullet roes (marine oil). Behavioral experiments were performed by means of two-choice tests to analyze the oil attractant effect compared with control (water or standard diet). The fatty acid composition of oils and the total lipid and fatty acid profile of medflies were characterized by chromatographic techniques. Behavioral bioassays showed that fixed oil obtained from M. fragrans (nutmeg butter) was more attractive than other oils. Medflies fed (24 hr) on marine oil showed significant changes in the total lipid and fatty acid profile induced by oil ingestion without toxic effects. However, 56% mortality was observed in insects fed on M. fragrans oil and no biochemical changes ascribable to oil ingestion were detected in the medflies that survived. Our results advance knowledge about the behavioral and biochemical response of medflies to fixed oils and will be potentially useful in developing new pest management strategies. PMID- 30302816 TI - Integrated network analysis and machine learning approach for the identification of key genes of triple-negative breast cancer. AB - Triple-negative breast cancer (TNBC) has attracted more attention compared with other breast cancer subtypes due to its aggressive nature, poor prognosis, and chemotherapy remains the mainstay of treatment with no other approved targeted therapy. Therefore, the study aimed to discover more promising therapeutic targets and investigating new insights of biological mechanism of TNBC. Six microarray data sets consisting of 463 non-TNBC and 405 TNBC samples were mined from Gene Expression Omnibus. The data sets were integrated by meta-analysis and identified 1075 differentially expressed genes. Protein-protein interaction network was constructed which consists of 486 nodes and 1932 edges, where 29 hub genes were obtained with high topological measures. Further, 16 features (hub genes), 12 upregulated (AURKB, CCNB2, CDC20, DDX18, EGFR, ENO1, MYC, NUP88, PLK1, PML, POLR2F, and SKP2) and four downregulated ( CCND1, GLI3, SKP1, and TGFB3) were selected through machine learning correlation based feature selection method on training data set. A naive Bayes based classifier built using the expression profiles of 16 features (hub genes) accurately and reliably classify TNBC from non-TNBC samples in the validation test data set with a receiver operating curve of 0.93 to 0.98. Subsequently, Gene Ontology analysis revealed that the hub genes were enriched in mitotic cell cycle processes and Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that they were enriched in cell cycle pathways. Thus, the identified key hub genes and pathways highlighted in the study would enhance the understanding of molecular mechanism of TNBC which may serve as potential therapeutic target. PMID- 30302818 TI - Disparate roles of CXCR3A and CXCR3B in regulating progressive properties of colorectal cancer cells. AB - Human C-X-C Motif Chemokine Receptor 3A (CXCR3A) and CXCR3B are two splice variants of CXCR3 that is involved in a variety of progressive processes of cancer cells, including proliferation, migration, invasion, and tumorigenicity. However, the molecular mechanisms of CXCR3 in colorectal cancer (CRC) remain incomplete understood. In the present study, a significantly up-regulated CXCR3 protein was firstly observed in CRC tissues and cell lines in comparison with the paired non-tumor tissues and normal intestinal epithelial cells, which was positively associated with CRC TNM stages. In contrast, CXCR3B was down-regulated in CRC tumor tissues compared with that in the corresponding paired paracancerous tissues, and negatively correlated with the TNM stages of cancer. Of interest, the overexpression of CXCR3A enhanced the progressive capacity of cell proliferation, migration, invasion in CRC LOVO and HCT116 cells in vitro, and the tumorigenicity in nude mice in vivo. Conversely, the overexpression of CXCR3B exhibited an opposite phenotype of CXCR3A, with an ability to inhibit the progressive properties in CRC cell lines in vitro and tumorigenesis in vivo. In addition, immunoblotting analysis further demonstrated that an increased expression of CXCR3A inhibited the expression of CXCR3B in CRC cells and NCM460 normal colon epithelial cells; vice verse, an overexpression of CXCR3B suppressed the expression of CXCR3A in these cells. These data imply that an interaction between the CXCR3A and CXCR3B may play an important regulatory role in tumorigenicity of CRC, which warrants for further investigation. PMID- 30302819 TI - Long-term GPi-DBS improves motor features in myoclonus-dystonia and enhances social adjustment. AB - BACKGROUND: Good short-term results of pallidal deep brain stimulation have been reported in myoclonus-dystonia. Efficacy and safety in the long term remain to be established. In addition, the actual impact of DBS treatment on social inclusion is unknown. The objective of this study was to assess the long-term clinical outcome, quality of life, and social adjustment of GPi-DBS in patients with epsilon-sarcoglycan (DYT11)-positive myoclonus-dystonia. METHODS: Consecutive myoclonus-dystonia patients with epsilon-sarcoglycan mutations who underwent GPi DBS were evaluated at least 5 years postoperatively. Motor symptoms were assessed using the Burke-Fahn-Marsden Dystonia Rating Scale including the Disability Scale, a composite score combining the rest and action parts of the Unified Myoclonus Rating Scale and modified Abnormal Involuntary Movement Scale. Standardized video-protocols were assessed by a blinded and external movement disorder specialist. Social adjustment, cognition, and mood were evaluated. RESULTS: Nine patients (5 women) with long-term GPi-DBS (8.7 +/- 3.1 years) were included. There was significant improvement in the composite myoclonus score (94.1% +/- 4% improvement; P = 0.008). Dystonia severity was also markedly improved (71.4% +/- 28.33% improvement; P = 0.008) as well as motor disability (88.3% +/- 20% improvement; P = 0.008) and abnormal involuntary movement score (71.1% +/- 15.0% improvement; P = 0.008). No patients experienced postoperative speech or gait problems or any permanent adverse effects. Eight of the 9 patients had fully enhanced social adjustment and personal achievement, with little or no mood or behavioral disorders. CONCLUSIONS: GPi-DBS seems to be a safe and efficacious treatment for medically refractory E-sarcoglycan myoclonus-dystonia, with sustained motor benefit, good quality of life, and social adjustment in long term follow-up.

AB - Genetic studies are continuing to generate volumes and variety of data that can be used to examine the genetic effects. Often the effect of a genetic variant varies by nongenetic measures, what is traditionally defined as gene-environment interaction (G*E). If the G*E term is neglected, estimates of the main effects can be substantially biased. We derive a general and convenient approximation to the magnitude of bias in the estimates due to omitting the G*E term. We show that the approximation is reasonably accurate in finite samples. We then apply the approximation in a study of Alzheimer's disease. PMID- 30302821 TI - Upregulated lncRNA small nucleolar RNA host gene 1 promotes 1-methyl-4 phenylpyridinium ion-induced cytotoxicity and reactive oxygen species production through miR-15b-5p/GSK3beta axis in human dopaminergic SH-SY5Y cells. AB - Long noncoding RNA (lncRNA) small nucleolar RNA host gene 1 (SNHG1) has been demonstrated to be upregulated and play a crucial role in the pathology of Parkinson's disease (PD). However, the exact role of SNHG1 and its underlying mechanisms in PD remains elusive. In this study, we found that SNHG1 and glycogen synthase kinase 3 beta (GSK3beta) were upregulated, but miR-15b-5p was downregulated in 1-methyl-4-phenylpyridinium ion (MPP+ )-treated SH-SY5Y cells. The upregulation of SNHG1 enhanced MPP+ -induced cellular toxicity in SH-SY5Y cells, as shown by decreased cell viability, increased ROS production, and increased number of TdT-mediated dUTP Nick-End labeling-positive cells, accompanied with the upregulation of cleaved caspase 3 and elevation of cytochrome C release. Meanwhile, SNHG1 knockdown presented the converse effects. SNHG1 was demonstrated to interact with miR-15b-5p. Moreover, SNHG1 could attenuate the inhibitory effects of miR-15b-5p on MPP+ -induced cytotoxicity and production of ROS. Besides, GSK3beta was identified as a direct target of miR-15b 5p. The inhibitory effects of SNHG1 knockdown or miR-15b-5p overexpression on MPP+ -induced cytotoxicity and reactive oxygen species (ROS) production were abrogated by upregulation of GSK3beta. Taken together, these results demonstrate that upregulated lncRNA SNHG1 promotes MPP+ -induced cytotoxicity and ROS production through the miR-15b-5p/GSK3beta axis in human dopaminergic SH-SY5Y cells, suggesting that SNHG1 may act as a potential therapeutic target for PD treatment in the future.

AB - Clustering has been widely conducted in the analysis of gene expression data. For complex diseases, it has played an important role in identifying unknown functions of genes, serving as the basis of other analysis, and others. A common limitation of most existing clustering approaches is to assume that genes are separated into disjoint clusters. As genes often have multiple functions and thus can belong to more than one functional cluster, the disjoint clustering results can be unsatisfactory. In addition, due to the small sample sizes of genetic profiling studies and other factors, there may not be sufficient evidence to confirm the specific functions of some genes and cluster them definitively into disjoint clusters. In this study, we develop an effective overlapping clustering approach, which takes account into the multiplicity of gene functions and lack of certainty in practical analysis. A penalized weighted normalized cut (PWNCut) criterion is proposed based on the NCut technique and an L 2 norm constraint. It outperforms multiple competitors in simulation. The analysis of the cancer genome atlas (TCGA) data on breast cancer and cervical cancer leads to biologically sensible findings which differ from those using the alternatives. To facilitate implementation, we develop the function pwncut in the R package NCutYX. PMID- 30302824 TI - Comprehensive mapping of human body skin hydration: A pilot study. AB - BACKGROUND: Previous studies analyzed a series of representative anatomical regions in the human body; however, there is a wide structural and cellular variability in the constitution of the skin. Our objective was to perform a comprehensive assessment of human skin hydration throughout the largest possible area. MATERIALS AND METHODS: Hydration was registered by Corneometer(r) CM825 probe in 23 anatomical regions of five healthy men. Each zone was analyzed by 2 cm segments in the supine, prone, and lateral positions. A total of 7863 measurements were registered. RESULTS: Differences in the degree of hydration among the prone, supine, and lateral regions were observed. The chest and back showed a pattern of increased hydration toward the neck area. Higher levels of hydration were evidenced in the proximal areas and in the regions near the elbow and knee. The regions of greater mechanical wear and with greater exposure to the sun exhibited a lower degree of hydration. CONCLUSION: The human skin exhibited hydration patterns influenced by anatomical function and the degree of sun exposure. Detailed information of the hydration patterns could serve as reference for the design of topical products, as an indicator of their effectiveness, and for the monitoring of skin pathologies. PMID- 30302825 TI - Hsa_circ_101280 promotes hepatocellular carcinoma by regulating miR-375/JAK2. AB - In this study, we sought to predict the effects of a certain circular RNA (circRNA), hsa_circ_101280 (also known as hsa_circ_0100929 and hsa_circ_SLAIN1), on hepatocellular carcinoma (HCC) cells and to determine the potential mechanism. After screening differentially expressed circRNAs in HCC tissues through Gene Expression Omnibus data analysis, hsa_circ_101280 was found to be highly expressed, and its high expression was verified in HCC cell lines with qRT-PCR along with the low expression of its downstream miRNA miR-375. Colony formation and flow cytometry assays showed that both hsa_circ_101280 silencing and miR-375 overexpression restrained proliferation and promoted apoptosis in HCC cells. JAK2 was identified as a downstream mRNA target of miR-375 by RNA pull-down and dual luciferase reporter gene assays, its expression in HCC cell lines were positively regulated by hsa_circ_101280 and negatively by miR-375 expression. Furthermore, the silencing of hsa_circ_101280 significantly inhibited the growth of HCC xenografts in nude mice, with the downregulated expression of JAK2. Overall, both the in vitro and in vivo studies revealed that hsa_circ_101280 largely facilitated the tumorigenesis of HCC, characterized by the promoted proliferation and suppressed apoptosis of HCC cells, by sponging miR-375 and upregulating JAK2. PMID- 30302826 TI - Advanced Materials for Next-Generation Spacecraft. AB - Spacecraft are expected to traverse enormous distances over long periods of time without an opportunity for maintenance, re-fueling, or repair, and, for interplanetary probes, no on-board crew to actively control the spacecraft configuration or flight path. Nevertheless, space technology has reached the stage when mining of space resources, space travel, and even colonization of other celestial bodies such as Mars and the Moon are being seriously considered. These ambitious aims call for spacecraft capable of self-controlled, self adapting, and self-healing behavior. It is a tough challenge to address using traditional materials and approaches for their assembly. True interplanetary advances may only be attained using novel self-assembled and self-healing materials, which would allow for realization of next-generation spacecraft, where the concepts of adaptation and healing are at the core of every level of spacecraft design. Herein, recent achievements are captured and future directions in materials-driven development of space technology outlined.

PMID- 30302828 TI - Sulfuration of an Fe-N-C Catalyst Containing Fex C/Fe Species to Enhance the Catalysis of Oxygen Reduction in Acidic Media and for Use in Flexible Zn-Air Batteries. AB - During the preparation of atomically dispersed Fe-N-C catalysts, it is difficult to avoid the formation of iron-carbide-containing iron clusters ("Fex C/Fe"), along with the desired carbon matrix containing dispersed FeNx sites. As a result, an uncertain amount of the oxygen reduction reaction (ORR) occurs, making it difficult to maximize the catalytic efficiency. Herein, sulfuration is used to boost the activity of Fex C/Fe, forming an improved system, "FeNC-S-Fex C/Fe", for catalysis involving oxygen. Various spectroscopic techniques are used to define the composition of the active sites, which include Fe-S bonds at the interface of the now-S-doped carbon matrix and the Fex C/Fe clusters. In addition to outstanding activity in basic media, FeNC-S-Fex C/Fe exhibits improved ORR activity and durability in acidic media; its half-wave potential of 0.821 V outperforms the commercial Pt/C catalyst (20%), and its activity does not decay even after 10 000 cycles. Interestingly, the catalytic activity for the oxygen evolution reaction (OER) simultaneously improves. Thus, FeNC-S-Fex C/Fe can be used as a high-performance bifunctional catalyst in Zn-air batteries. Theoretical calculations and control experiments show that the original FeNx active centers are enhanced by the Fex C/Fe clusters and the Fe-S and C-S-C bonds.

AB - The development of advanced electrode materials for various energy-storage systems, especially the fabrication of designed structures and morphologies of electrode materials, has attracted intense interest in both the academic and industrial fields. Among the various synthesis methods, electrostatic spray deposition (ESD) is a simple but versatile approach, by which materials can be fabricated with various morphologies, such as granular, dense, and porous, in an easily controllable manner. Herein, motivated by the rapid advancements of the given technology, a comprehensive introduction of ESD is provided, with emphasis on the kinds of materials and the types of morphology that can be obtained, along with the important control parameters. The progress on electrode materials, which are applied in a great variety of energy-storage systems, such as Li-ion batteries, Na-ion batteries, supercapacitors, Li-S batteries, and Li-O2 batteries, prepared by ESD is also summarized. How the specific morphologies designed by ESD improve the electrochemical performance for different types of electrode materials is also discussed. The aim is to promote the collaborative efforts among different communities to optimize and develop the ESD technique and to explore advanced electrode materials for energy storage.

AB - Lithium-metal batteries are considered one of the most promising energy-storage systems owing to their high energy density, but their practical applications have long been hindered by significant safety concerns and poor cycle stability. Solid state electrolytes (SSEs) are expected to improve not only the safety but also the energy density of Li-metal batteries. The key challenge for solid-state Li metal batteries lies in the low ionic conductivity of the SSEs and moreover the interface contact between the electrode and SSE. To achieve feasible solid-state Li-metal batteries, it is imperative that the ionic conductivity is improved, especially at the electrode-SSE interface. Herein, recent advances in interface engineering for solid-state Li-metal batteries are reported, mainly focusing on garnet-type SSEs. Various materials to modify the cathode-garnet and Li-garnet interfaces by intermediate layers, alloys, and polymer electrolytes are analyzed. Structural innovations for SSEs including composite electrolytes and multilayer SSE frameworks are reviewed, along with advanced characterization approaches to probe the interfaces, which will provide further insights for garnet-based solid state batteries. Future challenges and the great promise of garnet-based Li-metal batteries are discussed to close.

AB - Tin and its derivatives have provoked tremendous progress of high-capacity sodium ion anode materials. However, achieving high areal and volumetric capability with maintained long-term stability in a single electrode remains challenging. Here, an elegant and versatile strategy is developed to significantly extend the lifespan and rate capability of tin sulfide nanobelt electrodes while maintaining high areal and volumetric capacities. In this strategy, in situ bundles of robust hierarchical graphene (hG) are grown uniformly on tin sulfide nanobelt networks through a rapid (5 min) carbon-plasma method with sustainable oil as the carbon source and the partially reduced Sn as the catalyst. The nucleation of graphene, CN (with size N ranging from 1 to 24), on the Sn(111) surface is systematically explored using density functional theory calculations. It is demonstrated that this chemical-bonded hG strategy is powerful in enhancing overall electrochemical performance. PMID- 30302836 TI - A Surface Reconstruction Route to High Productivity and Selectivity in CO2 Electroreduction toward C2+ Hydrocarbons. AB - Electrochemical carbon dioxide reduction (CO2 ) is a promising technology to use renewable electricity to convert CO2 into valuable carbon-based products. For commercial-scale applications, however, the productivity and selectivity toward multi-carbon products must be enhanced. A facile surface reconstruction approach that enables tuning of CO2 -reduction selectivity toward C2+ products on a copper chloride (CuCl)-derived catalyst is reported here. Using a novel wet-oxidation process, both the oxidation state and morphology of Cu surface are controlled, providing uniformity of the electrode morphology and abundant surface active sites. The Cu surface is partially oxidized to form an initial Cu (I) chloride layer which is subsequently converted to a Cu (I) oxide surface. High C2+ selectivity on these catalysts are demonstrated in an H-cell configuration, in which 73% Faradaic efficiency (FE) for C2+ products is reached with 56% FE for ethylene (C2 H4 ) and overall current density of 17 mA cm-2 . Thereafter, the method into a flow-cell configuration is translated, which allows operation in a highly alkaline medium for complete suppression of CH4 production. A record C2+ FE of ~84% and a half-cell power conversion efficiency of 50% at a partial current density of 336 mA cm-2 using the reconstructed Cu catalyst are reported. PMID- 30302837 TI - Programmable Multicomponent Self-Assembly Based on Aromatic Amino Acids. AB - Construction of integrated self-assembly with ordered structures from two or more organic building blocks is currently a challenge, since it suffers from intrinsic systematic complexity and diverse competitive pathways. Here, it is reported that aromatic amino acid building units can be incorporated into two- or three component coassembly driven primarily by hydrogen bonding interactions without the assistance of metal-ligand and macrocycle-based host-guest interactions. The key strategy is to employ a C3 -symmetric molecule with alternative hydrogen bonding donor/acceptor sites that are able to bind either carboxylic acid or pyridine appended building units. Aromatic amino acids, C3 -symmetric compound, and bipyridine unit constitute a unique ternary mutual binding system, where three coassembly pathways including two pairwise formations and one ternary combination are unveiled, giving rise to two- and three-component self-assemblies with ordered structures, respectively. The pathway complexity lies in the structural parameter of aromatic amino acids, which can be programmable by controlling substituents at the alpha-position of amino acids. PMID- 30302838 TI - Diabetes knowledge of primary health care and specialist nurses in a major urban area. AB - AIM AND OBJECTIVES: To examine trends since a previous 2006-2008 survey in diabetes knowledge held by primary health care nurses and their use of national diabetes guidelines, perceived ability to advise diabetes patients and preferences for further diabetes education. BACKGROUND: The obesity epidemic has led to a rapid increase in the prevalence of prediabetes and type 2 diabetes and to greater expectations for an expanded role for primary health care nurses in the prevention and community management of diabetes. DESIGN: Cross-sectional survey using a self-administered questionnaire and telephone interview and adheres to the STROBE guidelines. METHODS: All nurses who provide community-based care in a major urban area were identified, and stratified by group, prior to random selection to participate in the study. A total of 1,416 practice, district (home care) and specialist nurses were identified who provide community-based care. Of the 459 who were randomly selected, 336 (73%) participated in 2016 and were compared with a representative sample of 287 nurses surveyed in 2006-2008. RESULTS: Compared with nurses in 2006-2008, significantly more nurses in 2016 used diabetes guidelines, knew that stroke was a diabetes-related complication, had a greater understanding of the pathology of diabetes and reported having sufficient knowledge to advise patients on laboratory results and improving outcomes through lifestyle changes. Despite these improvements, in 2016, only 24% of nurses could state that stroke was a complication of type 2 diabetes, only 37% felt sufficiently knowledgeable to advise patients on medications, and <20% could state that hypertension, smoking and the dyslipidaemia profile were important modifiable risk factors. CONCLUSION: There have been improvements in nurse's knowledge but gaps remain for cardiovascular outcomes and associated modifiable risk factors and medication management. RELEVANCE TO CLINICAL PRACTICE: Education programmes should focus on improving cardiovascular risk management in patients with type 2 diabetes. PMID- 30302839 TI - Compound heterozygous missense mutations p.Leu207Pro and p.Tyr544Cys in TGM1 cause a severe form of lamellar ichthyosis. AB - TGM1 is the most common gene responsible for lamellar ichthyosis. Previous studies have suggested that patients with lamellar ichthyosis carrying two missense mutations in TGM1 show significantly less severe phenotypes than those with at least one truncating mutation in TGM1. Here, we report a patient with severe lamellar ichthyosis who was compound heterozygous for TGM1 missense mutations, including a novel one. A 22-year-old Japanese man presented with large, dark brown, plate-like scales on the extremities and small adherent scales on the face and trunk. His other clinical findings included ectropion, hair loss, hypohidrosis, hyperthermia in summer, palmoplantar keratoderma and constriction of the fingers. Dermoscopy revealed accentuated sulci cutis with numerous large keratotic plugs in the cristae cutis. Histologically, orthohyperkeratosis and mild acanthosis were noted. Electron microscopy showed reduced cornified envelope thickness and numerous lipid droplets in the stratum corneum. Mutation analysis revealed the patient to be compound heterozygous for missense mutations, c.620T>C (p.Leu207Pro) and c.1631A>G (p.Tyr544Cys), in TGM1. Furthermore, we showed that TGM1 enzymatic activity was largely absent in his epidermis. These findings led us to diagnose him as having lamellar ichthyosis. This study has two important notions. First, even two missense mutations in TGM1 can cause severe lamellar ichthyosis. Second, this is the first report of dermoscopic findings of lamellar ichthyosis, implicating the obstruction of sweat glands by keratotic plugs in the pathogenesis of hypohidrosis in the disease. In conclusion, this study provides further insights into genotype-phenotype correlations and pathogenesis in lamellar ichthyosis.

AB - BACKGROUND: The eruption of primary teeth represents a stage of many challenges for parents. AIM: To investigate the occurrence of signs and symptoms related to the eruption of the primary dentition in children with congenital Zika syndrome. DESIGN: Longitudinal study developed with 79 children followed up for a period of 24 months. Data on sex, gestational age, low birthweight, microcephaly, signs and symptoms related to the dental eruption phase, and use and type of medication were collected. Data were presented by descriptive and inferential statistics (chi-square test). RESULTS: The majority (94.9%) exhibited simultaneously two or more signs and symptoms related to dental eruption. Increased salivation (91.1%), irritability (86.1%), and gingival itching (83.5%) were the most commonly reported signs and symptoms. Bivariate analysis showed association between elevation of body temperature and sex (P < 0.05). Almost two-thirds of mothers (63.3%) reported using medication to relieve symptoms presented by the child; however, the use of topical medication prevailed (57.1%). CONCLUSION: All children with congenital Zika syndrome presented manifestations related to the eruption of primary teeth, with increased salivation, irritability, and gingival pruritus. The use of ointments and gels was the option of mothers in the treatment of the oral discomfort presented by infants. PMID- 30302843 TI - Breastfeeding woman or lactating object? A critical philosophical discussion on the influence of Cartesian dualism on breastfeeding in the neonatal intensive care unit. AB - AIM: This discursive paper aims to bring to the foreground the ongoing influence of Cartesian dualism and other important contextual complexities on breastfeeding in the neonatal intensive care unit (NICU). BACKGROUND: Breastfeeding is widely supported as the optimal form of nutrition for the first 6 months of life and beyond. Amidst a myriad of contextual factors, current breastfeeding rates are below globally targeted goals. For premature and/or critically ill infants, the importance of receiving breast milk is often encouraged based on its immunological and nutritive benefits as opposed to the entirety of the breastfeeding interaction, underscoring the influence of dualism in the NICU. DESIGN: The impact of Cartesian dualism and other sociocultural underpinnings of breastfeeding focused within the NICU environment are illustrated through a critical, philosophical discussion. METHODS: Relevant historical context is provided followed by an overview of the realities of contemporary breastfeeding. These are presented as a frame of reference for the NICU breastfeeding experiences currently encountered by many mothers of preterm and critically ill neonates, further illustrated using a clinical exemplar as well as the author's own observations from neonatal nursing practice. RELEVANCE TO CLINICAL PRACTICE: Shifting away from a dualistic approach requires rethinking breastfeeding support interactions between NICU nurses and mothers. To address the disembodied and often mechanistic approach to care inherent in the dominant Western medical model, a relational approach to breastfeeding support in the NICU is suggested and discussed. CONCLUSION: Future research from a more critical lens is needed to examine the complex dynamics involved when nurses and mothers are negotiating decisions and processes related to infant feeding. In focusing on the relational dimensions of the breastfeeding experience, nurses can resist the dualistic influence and dominant discourses impacting infant feeding and motherhood in the 21st century. PMID- 30302842 TI - Iron Gall Ink Revisited: In Situ Oxidation of Fe(II)-Tannin Complex for Fluidic Interface Engineering. AB - The ancient wisdom found in iron gall ink guides this work to a simple but advanced solution to the molecular engineering of fluidic interfaces. The Fe(II) tannin coordination complex, a precursor of the iron gall ink, transforms into interface-active Fe(III)-tannin species, by oxygen molecules, which form a self assembled layer at the fluidic interface spontaneously but still controllably. Kinetic studies show that the oxidation rate is directed by the counteranion of Fe(II) precursor salts, and FeCl2 is found to be more effective than FeSO4 -an ingredient of iron gall ink-in the interfacial-film fabrication. The optimized protocol leads to the formation of micrometer-thick, free-standing films at the air-water interface by continuously generating Fe(III)-tannic acid complexes in situ. The durable films formed are transferable, self-healable, pliable, and postfunctionalizable, and are hardened further by transfer to the basic buffer. This O2 -instructed film formation can be applied to other fluidic interfaces that have high O2 level, demonstrated by emulsion stabilization and concurrent capsule formation at the oil-water interface with no aid of surfactants.

AB - AIMS AND OBJECTIVES: To explore the use of feminist poststructuralism (FPS) as a way to critique, understand and improve sexual health care and policy in healthcare settings. BACKGROUND: Sexual health is an important aspect of health; however, in healthcare settings, it often goes unaddressed by both healthcare providers and patients due to stigma, taboo, fear of embarrassment or uncertainty. Lack of attention to sexual health has been stated as a legitimate concern for patients across the lifespan; there remain gaps in implementing sexual health care discussions into practice in healthcare settings. DESIGN: A critical analysis will be presented to explore sexual health care and attitudes in the healthcare setting from patient and nursing perspectives using FPS. METHODS: Feminist poststructuralism is used to examine the meaning of experience that is personally, socially and institutionally constructed through relations of power. FPS will also be applied to understand how sexual health discourses are negotiated in healthcare settings. SQUIRE guidelines were used in the preparation of this paper (See Appendix S1). RELEVANCE TO CLINICAL PRACTICE: The application of a feminist poststructural lens to sexual health care in healthcare settings may be used by healthcare professionals to understand, question and challenge how social and institutional beliefs, values and practices surrounding sexual health, inclusive of a patient's sexual pleasure or sexual activity, are experienced by healthcare professionals and patients. This theoretical and methodological approach could lead to identifying possibilities for change in healthcare settings that are inclusive and supportive of sexual health care.

PMID- 30302846 TI - Broken expectations of early motherhood: Mothers' experiences of early discharge after birth and readmission of their infants. AB - BACKGROUND AND AIM: Today, mothers are discharged early after birth, and national monitoring shows an increase in readmission of infants. Readmission of the infant might diminish the possibility of bonding and weaken maternal confidence in taking care of the infant. The aim was to explore how new mothers experience the time from birth to being discharged after readmission with their infants. DESIGN: A phenomenological and hermeneutic study. Data were collected through telephone interviews. The study followed the COREQ requirements and was conducted in the Region of Southern Denmark in a University Hospital setting. Convenience sampling was applied, and eight mothers were included from November 2015-February 2016. Seven were interviewed. RESULTS: The data analysis revealed the following six themes: "Early discharge," "Being at home," "Readmission-shock or relief," "Problems with breastfeeding in early motherhood," "Empowering or disempowering guidance" and "Back home with broken expectations." These six themes were all covered by the overall theme: "Broken expectations of a tranquil beginning of early motherhood." CONCLUSIONS: Our study points out that mothers wish for a tranquil beginning with their infants at home. Some already experienced problems at home, while others first were confronted at the check-up at the outpatient clinic. Yet the common denominator was that the mothers experienced broken expectations regarding early motherhood when facing readmission. Readmission may influence the initial process either positively or negatively, depending on how the mothers experience their challenges and how the healthcare professionals support them. This highlights the importance of the way in which healthcare professionals support new mothers when they are readmitted. The study emphasises the importance of maternal feelings of security and confidence in their maternal role, as they are closely connected to the process of becoming a mother. PMID- 30302847 TI - Regulation of miR-125a expression by rs12976445 single-nucleotide polymorphism is associated with radiotherapy-induced pneumonitis in lung carcinoma patients. AB - BACKGROUND: The expression of miR-125 is regulated by an single-nucleotide polymorphism (SNP), rs12976445, which may be involved in the risk of pneumonitis among non-small-cell lung carcinoma patients undergoing the radiotherapy. We investigated this hypothesis via clinical data analysis and in vitro experiments. METHODS: An online microRNA (miRNA) database (www.mirdb.org) and luciferase reporter assays were used to confirm the role of transforming growth factor-beta1 (TGFB1) as a target gene of miR-125a. Quantification by real-time PCR and Western blot analysis were used to measure the expression of miRNA-125a and TGFB1 among different groups (carrying CC, CT, and TT genotypes of rs12976445) or cells transfected with a scramble control, miR-125a mimics, TGFB1 siRNA, or miR-125a inhibitors. RESULTS: We evaluated 699 NSCLC patients and found that the patients carrying the TT or CT genotype of rs12976445 had a higher risk of radiotherapy induced pneumonitis. Computational analysis and luciferase assays validated that TGFB1 is a target gene of miR-125a. The expression level of miR-125a mRNA was significantly downregulated in the CT and TT groups, while the expression levels of TGFB1 and SMAD2 were significantly upregulated in the CC group. The expression of TGFB1 and SMAD2 was regulated by miR-125a in A549 cells. CONCLUSION: The rs12976445 SNP in miR-125a is associated with the risk of pneumonitis after in lung cancer patients undergoing the radiotherapy by regulating the expression of miR-125a and TGFB1. PMID- 30302848 TI - Attitudinal and behavioural responses to increasing tobacco control regulation among high smoking prevalence groups: A qualitative study. AB - INTRODUCTION AND AIMS: Despite substantial reductions in smoking prevalence in many countries, rates remain high among people who are experiencing disadvantage. This study aimed to explore attitudinal and behavioural responses to population wide tobacco control policies among Australian smokers experiencing disadvantage. DESIGN AND METHODS: Semi-structured qualitative interviews were conducted with 84 smokers attending community service organisations in the mental health, homelessness, and alcohol and other drug sectors. Interviewees discussed various tobacco control policies (tobacco taxes, smoke-free areas, plain packaging and graphic health warnings). The interview transcriptions were coded and thematically analysed. RESULTS: Responses to tobacco taxes were mixed. Some interviewees reported smoking less as a result of price increases, while others reallocated funds from other budget areas. Many perceived smoke-free area policies as effective, although some described strategies they use to circumvent this policy, thereby diminishing its effectiveness. Plain packaging and graphic warnings were perceived as being least effective. DISCUSSION AND CONCLUSIONS: While tobacco control policies can elicit intended attitudinal and behavioural responses, additional efforts are needed to enhance their effectiveness among smokers experiencing disadvantage. Future efforts to reduce smoking rates should address responses that diminish policy effectiveness among groups exhibiting high smoking prevalence. This could be achieved through strategies that address the specific needs of these groups, such as providing additional cessation support, enforcing existing smoke-free policies in ways that minimise inequitable effects, and addressing self-exempting beliefs. PMID- 30302849 TI - Quality improvement programme of ultrasound based fetal anatomy screening using large scale clinical audit. AB - OBJECTIVE: Large scale audit and peer review of ultrasound images is advantageous, but is rarely performed consistently as it is time-consuming and expensive. Here we investigate the effect of large scale audit of routine fetal anatomy scans to assess if a full clinical audit cycle could improve clinical image acquisition standards. METHODS: A large scale, clinical, retrospective audit was conducted of ultrasound images from all routine anomaly scans undertaken in a UK hospital (from 18 weeks + 0 days to 22 weeks + 6 days) for one calendar year, to build a baseline understanding of the performance of sonographers. Targeted actions were undertaken in response to the findings with the aim of improving departmental performance. A second full year audit was then performed. An independent pool of sonographers used an online tool to assess all scans in two ways: scan completeness (i.e. were all images archived?) and image quality using objective scoring (i.e. were images of high quality?). Both were assessed at departmental level and at individual sonographer level. A 10% random sample of scans was used to assess inter-observer reproducibility. RESULTS: Images (n=103,501) from 6,257 anomaly scan examinations undertaken by 22 sonographers were assessed in cycle 1 of the audit; in cycle 2, 153,557 images from 6,406 scans undertaken by 25 sonographers were evaluated. The analysis was performed on the 20 sonographers participating in both cycles. Departmental median scan completeness improved from 72% in the first year to 78% at the second assessment (p<0.001); median image quality score across all fetal views improved from 0.83 to 0.86 (p<0.001). The improvement was greatest for those sonographers who were performing poorest on the first audit: the 14% of poorest performing sonographers showed more than 30% improvement in scan completeness; and 11% showed more than 10% improvement in image quality. Inter-observer repeatability of scan completeness and image quality scores across different fetal views were similar to the published literature. CONCLUSION: Clinical audit and a set of targeted actions helped improve sonographer scan acquisition completeness and scan quality. Such adherence to recommended clinical acquisition standards may increase the likelihood of correct measurement and thereby fetal growth assessment; and should allow better detection of abnormalities. As such large scale audit is time consuming, further advantages would be achieved if this process could be automated. This article is protected by copyright. All rights reserved. PMID- 30302850 TI - Male partners' experiences of caregiving for women with cervical cancer-a qualitative study. AB - AIMS AND OBJECTIVES: This study aimed to develop knowledge on the experiences of male partners of women with cervical cancer during and after the illness. We explore men's experiences of becoming caregivers as well as how the illness trajectory affects or has affected the relationship. BACKGROUND: Receiving a cancer diagnosis has a significant impact on the lives of both the cancer patient and their family members. However, studies of male partners' experiences with cancer patients are scarce. Additionally, cervical cancer and its impact on male caregivers are less explored than how other cancer diagnoses impact male caregivers. The theoretical concept of caring masculinities is helpful to interpret men's experiences as caregivers and partners. DESIGN: The study employs a qualitative design with semi-structured interviews with six men/partners recruited through the gynaecological section at a hospital. COREQ reporting guidelines have been applied. FINDINGS: Based on our analyses, we find that men's experiences of being caregivers and partners of women treated for cervical cancer are multifaceted, comprising emotional and practical aspects. However, three main findings stand out as particularly significant for men in the context of cervical cancer: loneliness, an altered sexual relationship and shared feelings of vulnerability. CONCLUSIONS: The men describe an interdependence in the relationship with the women but also how the relationships have been seriously altered, particularly when it comes to sexuality. These findings resonate with hegemonic as well as caring masculinities. RELEVANCE TO PRACTICE: Complex issues of intimacy and sexuality should be a pivotal element in educating future healthcare professionals. We strongly suggest that issues such as dealing with masculinity and caregiving roles should be on the agenda and reflected upon in teaching and supervising in clinical practice. A broader approach to sexual health and relationships is needed in the patient-clinician relationships, including information about human papillomavirus. PMID- 30302851 TI - Harm reduction strategies related to dosing and their relation to harms among festival attendees who use multiple drugs. AB - INTRODUCTION AND AIMS: Polysubstance users are a high-risk population for negative health-related consequences. Although some studies have described harm reduction strategies adopted by polysubstance users, studies have not examined their effectiveness in minimising health-related consequences. We aimed to identify dosing-related harm reduction strategies in a sample of polysubstance using dance festival attendees, and explore the relationship between harm reduction strategies and self-reported adverse health consequences. DESIGN AND METHODS: Data were examined for 1226 past-year dance festival attendees who self identified as past-year multiple drug users. We conducted bivariable and multivariable analyses to explore relationships between six dosing-related harm reduction strategies and 13 self-reported adverse consequences. RESULTS: Self reported use of dosing-related harm reduction strategies was prevalent, mainly avoidance of mixing depressants (69.2%) and setting limits on quantity (62.2%). Frequent users of harm reduction strategies reported experiencing fewer adverse health consequences (P values < 0.05). Those who reportedly set limits on quantity were at decreased odds of experiencing a bad mood after drug use, sexual difficulties while under drug influence, injuries or fractures while under drug influence, and involvement in fights or being attacked while under drug influence (P values < 0.05). Moreover, those who report frequently avoid mixing depressants were at decreased odds of experiencing headache, loss of consciousness, drop in blood pressure, injuries of fractures, and fights or attacks (P values < 0.05). DISCUSSION AND CONCLUSIONS: Adoption of dosing-related harm reduction strategies appears to be associated with less drug-related harm among polysubstance-using festival attendees. Findings may inform organisations and policymakers in the designing of harm reduction interventions with this population.

PMID- 30302853 TI - Long-term treatment with ivabradine in transgenic atrial fibrillation mice counteracts hyperpolarization-activated cyclic nucleotide gated channel overexpression. AB - INTRODUCTION: Recent studies have demonstrated that ivabradine (IVA), is a selective inhibitor of funny current (If) and exerts antiarrhythmic effects in the settings of various diseases such as heart failure and myocardial ischemia. However, little is known regarding the effects of long-term IVA treatment on If current and hyperpolarization-activated cyclic nucleotide gated (HCN) channel overexpression. METHODS AND RESULTS: We investigated both the If current and HCN channel expression in wild-type (WT) mice and transgenic (TG) atrial fibrillation (AF) mice (heart-specific overexpressing of (pro) renin receptor TG mice) and examined the effects of IVA on the If current and HCN channel expression, and whether those effects were sufficient to prevent an AF episode. Compared with WT mice, the If current density (at -170 mV: TG, -39.6 +/- 4.6 pA/pF; WT, -26.9 +/- 3.0 pA/pF; P < 0.001) and activation kinetics (V1/2 : TG, -109.45 +/- 1.35 mV; WT, -128.20 +/- 1.65 mV), as well as HCN2 and HCN4 messenger RNA expression and HCN4 protein expression were significantly increased in the atrial myocytes of TG mice. After 4 months of IVA treatment (7 mg/kg per day orally) the effects of IVA on TG AF mice were accompanied by the inhibition of upregulation of HCN2 and HCN4 protein expression in atrial tissue, and then resulted in a uniform If loss of function. Furthermore, we observed that ivabradine significantly decreased the incidence of AF in the TG mice (41.2% in TG mice, 16.7% in TG + IVA mice; P < 0.01). CONCLUSION: IVA reduced the incidence of AF in mice, and the antiarrhythmic effects of IVA are not limited to heart rate reduction, as they partially counteract HCN overexpression and reverse electrophysiological cardiac remodeling by attenuating If gain-of-function. PMID- 30302854 TI - Assessment of microvascular dysfunction in acute limb ischemia-reperfusion injury. AB - BACKGROUND: Ischemia-reperfusion (I/R) injury involves damage to the microvessel structure (eg, increased permeability) and function (blunted vasomodulation). While microstructural damage can be detected with dynamic contrast-enhanced (DCE) MRI, there is no diagnostic to detect deficits in microvascular function. PURPOSE: To apply a novel MRI method for evaluating dynamic vasomodulation to assess microvascular dysfunction in skeletal muscle following I/R injury. STUDY TYPE: Prospective, longitudinal. ANIMAL MODEL: Twenty-three healthy male adult Sprague-Dawley rats. FIELD STRENGTH/SEQUENCE: Dynamic T1 fast field echo imaging at 3.0T with preinjection T1 mapping. ASSESSMENT: Injury in the left hindlimb was induced using a 3-hour I/R procedure. Longitudinal MRI scanning was performed up to 74 days, with animals completing assessment at different intervals for histological and laser Doppler perfusion validation. Pharmacokinetic parameters Ktrans and ve were determined following i.v. injection of gadovist (0.1 mmol/kg). Vasomodulatory response was probed on gadofosveset (0.3 mmol/kg) using hypercapnic gases delivered through a controlled gas-mixing circuit to induce vasoconstriction and vasodilation in ventilated rats. Heart rate and blood oxygen saturation were monitored. STATISTICAL TESTS: Two-way analysis of variance with Tukey-Kramer post-hoc analysis was used to determine significant changes in vasomodulatory response, Ktrans , and ve . RESULTS: This new MRI technique revealed impaired vasomodulation in the injured hindlimb. Vasoconstriction was maintained, but vasodilation was blunted up to 21 days postinjury (P < 0.05). However, DCE-MRI measured Ktrans and ve were significantly (P < 0.05) different from baseline only during acute inflammation (Day 3), with severe inflammation noted on histology. DATA CONCLUSION: While conventional DCE-MRI shows normalization after the acute phase, our new approach reveals sustained functional impairment in muscle microvasculature following I/R injury, with compromised response in vasomotor tone present for at least 21 days.

AB - AIM: There have been no previous studies of health-related quality of life (HRQOL) among adults aged 65 years and older with disabilities in Serbia. The aim of study was to identify predictors of HRQOL in the context of sociodemographic characteristics, disability aetiology, comorbid diseases, indices of comorbidities, realization of social rights, and domestic violence. METHODS: The cross-sectional study involved 275 consecutive elderly outpatients with disabilities. They were recruited by general practitioners at Primary Health Centers in Belgrade, Serbia, from March to May 2015. Data were acquired through face-to-face interviews and general practitioners' charts, while the generic 36 item Short Form Health Survey was used to assess HRQOL. In statistical analysis, Student's t-test, Z-test, Spearman's correlation test, and both univariate and multivariate linear regression were performed. RESULTS: Multivariate analysis revealed that a higher Functional Comorbidity Index (beta = -0.194, P < 0.01) and not asking for realization of right to assistance and care financial benefits (beta = -0.142, P < 0.05) were predictors of a lower scores Mental Composite Score (F = 9.262; P < 0.001). Not asking for realization of right to assistance and care financial benefits (beta = -0.187, P < 0.01), congestive heart failure (beta = -0.123, P < 0.05), and stroke (beta = -0.120, P < 0.05) were predictors of a lower Physical Composite Score (F = 7.169, P < 0.001). CONCLUSIONS: This study provides valuable data for better understanding the underlying factors associated with the HRQOL of elderly persons with disabilities, and currently, these are the only available data of their kind in Serbia. National authorities could identify predictors of HRQOL as a basic starting point for improving the social welfare and health-care systems. Better prevention and management of clinical factors, increased access to social services, and enhanced delivery of social services will improve the ageing process and HRQOL of this vulnerable population. PMID- 30302856 TI - Reinforce the antitumor activity of CD8+ T cells via glutamine restriction. AB - The antitumor activity of activated CD8+ T cells in the tumor microenvironment seems to be limited due to their being metabolically unfit. This metabolic unfitness is closely associated with T-cell exhaustion and impairment of memory formation, which are barriers to successful antitumor adoptive immunotherapy. We therefore assessed the role of glutamine metabolism in the antitumor activity of CD8+ T cells using a tumor-inoculated mouse model. The adoptive transfer of tumor specific CD8+ T cells cultured under glutamine-restricted (dGln) conditions or CD8+ T cells treated with specific inhibitors of glutamine metabolism efficiently eliminated tumors and led to better survival of tumor-inoculated mice than with cells cultured under control (Ctrl) conditions. The decreased expression of PD-1 and increased Ki67 positivity among tumor-infiltrating CD8+ T cells cultured under dGln conditions suggested that the inhibition of glutamine metabolism prevents CD8+ T-cell exhaustion in vivo. Furthermore, the transferred CD8+ T cells cultured under dGln conditions expanded more efficiently against secondary OVA stimulation than did CD8+ T cells under Ctrl conditions. We found that the expression of a pro-survival factor and memory T cell-related transcription factors was significantly higher in CD8+ T cells cultured under dGln conditions than in those cultured under Ctrl conditions. Given these findings, our study uncovered an important role of glutamine metabolism in the antitumor activity of CD8+ T cells. The novel adoptive transfer of tumor-specific CD8+ T cells cultured in glutamine-restricted conditions may be a promising approach to improve the efficacy of cell-based adoptive immunotherapy. PMID- 30302859 TI - How do neonatal units within the Australian and New Zealand Neonatal Network manage ex-preterm infants with severe chronic lung disease still requiring major respiratory support at term? AB - AIM: The aim was to survey the Australian and New Zealand Neonatal Network (ANZNN) member units regarding current services and management guidelines for the ex-premature infant with severe chronic lung disease (CLD) still requiring significant respiratory support at term. METHODS: A 16-question survey was sent to clinical directors of all Level 3 units in Australia and New Zealand via the network. Reminder emails were sent, as required, to prompt a satisfactory response rate. RESULTS: Survey responses were received from 26 of the 29 (90%) ANZNN Level 3 units. At 37 weeks' corrected gestation, over 90% of the units provide ongoing respiratory support in the neonatal intensive care unit (NICU). However, by 50 weeks, ongoing care is provided in several settings, including NICU, high dependency unit (HDU)/paediatric intensive care unit or respiratory wards. The majority (76%) of units arrange transfer on an ad hoc basis, but six units (24%) have set criteria for transfer based on gestation, workload and respiratory requirement. Three units declared a maximum age in NICU (44, 46 or 48 weeks). A variety of approaches were used to identify infants who were likely to require transfer, and 78% of units had a staff member assigned to assist transition. Three units stated that they had a home ventilation programme suitable for these infants. No unit supplied a guideline on tracheostomy or specific respiratory management post-term. CONCLUSION: Despite a significant number of babies requiring ongoing support for severe CLD, the location of the service appears very variable, and there is a lack of specific written guidelines. PMID- 30302857 TI - Primary breast diffuse large B-cell lymphoma in the rituximab era: Therapeutic strategies and patterns of failure. AB - Primary breast diffuse large B-cell lymphoma (PB-DLBCL) is a rare subtype of DLBCL with limited data on patterns of failure. This multicenter study aimed to define the optimum treatment strategy and patterns of failure for PB-DLBCL patients. We retrospectively reviewed data on 108 PB-DLBCL patients from 21 Chinese medical centers. Only patients with localized disease (involvement of breast and localized lymph nodes) were included. After a median follow-up of 3.2 years, 32% of patients developed progression or relapse. A continuous pattern of relapse was observed, characterized by frequent late relapses in the contralateral breast and central nervous system (CNS). Although rituximab significantly reduced the overall cumulative risk of progression or relapse (5 year cumulative risk 57% vs 24%, P = .029), it had limited effect on the reduction of breast relapse (P = .46). Consolidative radiotherapy significantly decreased the risk of breast relapse, even in the subgroup of patients treated with rituximab (5-year cumulative risk 21.2% vs 0%, P = .012). A continuous risk of CNS progression or relapse up to 8.2 years from diagnosis was observed (10 year cumulative risk 28.3%), with a median time to CNS relapse of 3.1 years. Neither rituximab nor prophylactic intrathecal chemotherapy significantly decreased the risk of CNS relapse. In summary, our study indicates that PB-DLBCL has a continuous pattern of relapse, especially with frequent late relapses in the CNS and contralateral breast. Rituximab and RT confer complementary benefit in the reduction of relapse. However, neither the addition of rituximab nor prophylactic intrathecal chemotherapy could effectively prevent CNS relapse for PB-DLBCL patients. PMID- 30302858 TI - A Dimeric 2,9-Diamino-1,10-phenanthroline Derivative Improves Alternative Splicing in Myotonic Dystrophy Type 1 Cell and Mouse Models. AB - Expanded r(CUG) repeats are the cause of the neurological disorder myotonic dystrophy type 1 (DM1). The pathological features of DM1 include the formation of ribonuclear foci containing expanded r(CUG) repeats, which sequester the MBNL1 protein and lead to the misregulation of alternative pre-mRNA splicing. Small molecules that bind to the r(CUG) repeats and improve alternative splicing have therapeutic potential in the treatment of DM1. Herein, the synthesis of DDAP (a dimeric form of the CUG-binding molecule DAP reported previously), its binding properties to r(CUG) repeats, and its effect on the misregulation of splicing are reported. The surface plasmon resonance assay, circular dichroism spectra, and ESI-TOF mass spectrometry results confirmed the binding of DDAP to r(CUG)9 repeats. Studies on a DM1 cell model and a DM1 mouse model revealed that DDAP was partially effective in the recovery of the pre-mRNA splicing defects. The mechanism underlying this recovery was studied in vitro through a competitive binding assay, and suggested that DDAP could interfere with the binding of MBNL1 to r(CUG) repeats in a concentration-dependent manner. PMID- 30302860 TI - Harnessing the gatekeepers of glucocorticoids for chemoprevention of non-melanoma skin cancer. AB - Despite effective surgical methods for non-melanoma skin cancer (NMSC), patients suffer from tissue damage, scarring, or even disfigurement; thus, there is a need for chemopreventive approaches. Because of the complex interplay between glucocorticoids (GCs), inflammation, and cancer, we sought to determine the role of 11beta-hydroxysteroid dehydrogenase 1 and 2 (11betaHSD1 and 2) in regulating GCs during skin cancer development and progression. 11betaHSDs modulate the activation of GCs in a tissue-specific manner and have been reported to play a role in development and progression of other types of cancer, but their role has not yet been reported in NMSC. Here, we found a significant upregulation of 11betaHSD2 protein in skin cancer cells when compared to normal skin cells, suggesting a role for this enzyme in the multifactorial process of skin cancer development. In addition, inhibition of 11betaHSD2 with siRNA resulted in significant reduction in colony formation in vitro. Finally, our in vivo study elucidated that inhibition of 11betaHSD2 with pharmacological inhibitor, Glycyrrhetinic acid (GA) could significantly diminish tumorigenesis in a well studied in vivo mouse model of NMSC. Overall, these studies highlight for the first time a potential novel role for 11betaHSD2 in NMSC development and may allow for new GC treatment approaches capable of avoiding deactivation by the enzyme. If 11betaHSD2 can be inhibited as we have done here, or circumvented using modified GCs, this may lead to more efficacious outcomes for NMSC patients by preventing deactivation of the GC and minimizing resistance. PMID- 30302861 TI - Validation of the Early Development Instrument for children with special health needs. AB - AIM: Population-level data on the development of children with special health needs attending primary school can assist special education, health and service delivery strategies. This study aims to determine whether results of the Early Development Instrument (EDI) can be interpreted and used with the same confidence for children with special health needs as for those who are typically developing. Psychometric properties of the EDI for kindergarteners with identified special health needs are examined. METHODS: Data for children with a special health need designation come from a database of all Canadian provincial implementations of the EDI between 2004 and 2014. Item and domain characteristics (distributions of scores and measures of internal consistency) of the EDI were examined. Construct validation was assessed by correlating EDI scores with gender and age. The fit of the original factor structure of the EDI was evaluated using confirmatory factor analysis. RESULTS: Data for 29 692 children (69.8% male) were analysed. The performance of items and domains was similar to that of typically developing children. As expected, boys scored lower on all EDI domains (Cohen's d: 0.03 0.46) and a general, but non-significant, positive trend was observed between age and EDI scores. The factor structure of the EDI in this population yielded similar goodness-of-fit statistics as those reported in studies with typically developing children. CONCLUSION: Results of this investigation support the validity of the EDI in children with special health needs, paving the way for a more extensive use of EDI data for this vulnerable, yet often neglected, population. PMID- 30302862 TI - Effect of autonomic influences to induce triggered activity in muscular sleeves extending into the coronary sinus of the canine heart and its suppression by ranolazine. AB - INTRODUCTION: Extrasystoles arising from the muscular sleeves associated with the pulmonary veins (PV), superior vena cava (SVC), and coronary sinus (CS) are known to precipitate atrial fibrillation (AF). The late sodium channel current (INa ) inhibitor ranolazine has been reported to exert antiarrhythmic effects in canine PV and SVC sleeves by suppressing late phase 3 early and delayed after depolarization (EAD and DAD)-induced triggered activity induced by parasympathetic and/or sympathetic stimulation. The current study was designed to extend our existing knowledge of the electrophysiological and pharmacologic properties of canine CS preparations and assess their response to inhibition of late INa following autonomic stimulation. METHODS: Transmembrane action potentials were recorded from canine superfused CS using standard microelectrode techniques. Acetylcholine (ACh, 1 uM), isoproterenol (Iso, 1 uM), high calcium ([Ca2+ ]o = 5.4 mM), or a combination were used to induce EADs, DADs, and triggered activity. RESULTS: Action potentials (AP) recorded from the CS displayed short and long AP durations (APD), with and without phase 4 depolarization (n = 19). Iso induced DAD-mediated triggered activity. The combination of sympathetic and parasympathetic agonists resulted in late phase 3 EAD-induced triggered activity in all CS preparations. Ranolazine (5-10 uM) suppressed late phase 3 EAD- and DAD-induced triggered activity in 8 of 8 preparations. Subthreshold stimulation induced a prominent hyperpolarization that could be suppressed by atropine. CONCLUSIONS: Our results suggest the important role of parasympathetic innervation in the activity of the CS. Autonomic influences promote DAD- and late phase-3-EAD-mediated triggered activity in canine CS, thus generating extrasystolic activity capable of initiating atrial arrhythmias. Ranolazine effectively suppresses these triggers. PMID- 30302863 TI - Arterial Spin Labeling MRI to Measure Cerebral Blood Flow in Untreated Ischemic Stroke. AB - BACKGROUND AND PURPOSE: This study aims to investigate the significance of regional hyperperfusion (RH) detected by arterial spin labeling (ASL) in a group of untreated stroke patients, within 24-36 hours after symptom onset. The relationship between RH volume and infarcted volume (DIV) as defined on diffusion weighted images (DWIs) was evaluated. METHODS: Of the 346 consecutive acute stroke patients who attended our center, we retrospectively reviewed MRI studies of 47 patients who were ineligible for standard treatment with intravenous tissue plasminogen activator. The MRI study included ASL and DWI. The ASL-derived cerebral blood flow (CBF) maps were coregistered on the DWI images. RH volume and DIV were calculated and compared. Patient NIHSS scores were also evaluated at admission, discharge, and after 1 and 6-month follow-up. RESULTS: Twenty-two patients showed RH with CBF twice than baseline. In all 22 patients, RH overlaps with DWI infarcted area. No significant difference (P = .94) between RH volume and DIV was found (7.2 +/- 9.6 and 9.0 +/- 11.9 cm3 ). The Pearson's correlation coefficient between RH and DIV was .93. On univariate analysis, a significant difference was found between patient's groups on NIHSS at any time points, after covariates adjustment NIHSS difference was significant only at admission. CONCLUSIONS: The study showed that ASL perfusion could be an integral part of the MRI examination in the assessment of 24-36 hours not-treated stroke patients as sustained RH group had improved outcomes. More importantly, ASL perfusion may provide evidence of beneficial effects of reperfusion induced by recanalization treatment. PMID- 30302864 TI - Diffusion tensor imaging of white matter in patients with prediabetes by trace based spatial statistics. AB - BACKGROUND: Prediabetes is an intermediate state in which blood glucose is higher than normal but does not meet the diagnostic criteria for diabetes. Diffusion tensor imaging (DTI) is an MRI method that can sensitively detect microscopic lesions in the white matter of the brain, but most previous DTI studies only focused on patients with diabetes, and little is known about prediabetes. PURPOSE: To investigate the changes in the microstructure of brain white matter in prediabetes patients using DTI and trace-based spatial statistics (TBSS). STUDY TYPE: Prospective. POPULATION: Sixty subjects (30 patients with prediabetes and 30 healthy volunteers) were enrolled. FIELD STRENGTH/SEQUENCE: 3.0T/DTI-MRI sequence with single-shot echo-planar imaging sequence (SE-EPI). ASSESSMENT: DTI data were collected and analyzed using the TBSS method in the FMRIB software library. STATISTICAL TESTS: DTI using a two-sample t-test. Pearson correlation analysis was performed on DTI values and neuropsychology scale results (mini mental state examination [MMSE], Montreal cognitive assessment [MoCA], self rating anxiety scale [SAS], and self-rating depression scale [SDS]) RESULTS: Compared with the control group, the fractional anisotropy (FA) values in the right part of the corpus callosum body (bCC) (P = 0.035), the right superior longitudinal fasciculus (SLF.R) (P = 0.047), and the left superior longitudinal fasciculus (SLF.L) in the prediabetic group were reduced (P = 0.040). DATA CONCLUSION: DTI as a noninvasive technique can assess early changes in the white matter microarchitecture of patients with prediabetes. LEVEL OF EVIDENCE: 2 Technical Efficacy: Stage 2 J. Magn.

AB - This study examines the effect of demographic variables on the beliefs of teachers of English as a foreign language (EFL) about their preparedness to include dyslexic learners in mainstream classrooms in Greece, Cyprus, and Poland and identifies their professional development needs. Statistically significant multivariate analysis effects were obtained for country, training, teaching experience with dyslexic learners, and school type. Unlike overall teaching experience and completed level of education (degree), the type of teaching experience with dyslexic EFL learners (direct contact and personal involvement in teaching) seems to shape the perception of teacher preparedness to successfully include these learners. Other interesting tendencies were identified such as between-country differences concerning sources of prior professional knowledge on EFL and dyslexia as well as preferences for particular modes of training. The paper highlights the demand for professional training on EFL and dyslexia as this was confirmed across the three countries. PMID- 30302866 TI - Functional Brain Network Changes Following Use of an Allostatic, Closed-Loop, Acoustic Stimulation Neurotechnology for Military-Related Traumatic Stress. AB - BACKGROUND AND PURPOSE: Post-traumatic stress disorder is associated with connectivity changes in the default mode, central executive, and salience networks, and other brain regions. This study evaluated changes in network connectivity associated with usage of High-resolution, relational, resonance based electroencephalic mirroring (HIRREM(r) ; Brain State Technologies, Scottsdale, AZ), a closed-loop, allostatic, acoustic stimulation neurotechnology, for military-related traumatic stress. METHODS: Eighteen participants (17 males, mean age 41 years [SD = 7], 15 active duty) enrolled in an IRB approved pilot trial for symptoms of military-related traumatic stress. Participants received 19.5 (1.1) HIRREM sessions over 12 days. Symptoms, physiological and functional measures, and whole brain resting MRI were collected before and after HIRREM. Six whole brain functional networks were evaluated using summary variables and community structure of predefined networks. Pre to postintervention change was analyzed using paired-sample statistical tests. RESULTS: Postintervention, there was an overall increase in connectivity of the default mode network (P = .0094). There were decreases of community structure in both the anterior portion of the default mode (medial prefrontal cortex, P = .0097) and in the sensorimotor (P = .005) network. There were no statistically significant changes at the whole brain level, or in the central executive, salience, or other networks analyzed. Participants demonstrated significant improvements in clinical symptoms, as well as autonomic cardiovascular regulation, which have been reported previously. CONCLUSIONS: Use of closed-loop, allostatic, acoustic stimulation neurotechnology (HIRREM) was associated with connectivity changes in the default mode and sensorimotor networks, in directions that may have explained the subjects' clinical improvements.

AB - BACKGROUND: Maternal haemodynamics change significantly during Caesarean Section complicated by massive haemorrhage or severe hypertensive disease. Cardiac output (CO) monitoring aids early, goal-directed haemodynamic therapy. The aim of this study was to record haemodynamic changes observed during Caesarean section using invasive (LiDCOrapid) and non-invasive (NICOM(r) ) devices and to assess agreement between the two devices in measuring CO. METHODS: Simultaneous hemodynamic measurements were taken from the two devices using standardized techniques in women undergoing Caesarean section at high-risk of haemodynamic instability. Agreement was assessed using Bland-Altman plots and the Agreement/Tolerable Index (ATI). Agreement analyses were performed for repeated measures in subjects and using centiles. RESULTS: 307 paired data from 10 patients were analysed. The mean bias (LiDCOrapid - NICOM(r) ) was 3.05 L.min-1 (95% CI 1.89 to 4.21). Limits of Agreement ranged from -1.58 L.min-1 (95% CI 4.47 to -0.14) to 7.68 L.min-1 (95% CI 6.24 to 10.56). The resulting agreement interval was 9.26 L.min-1 which returned 2.3 as the ATI. CONCLUSION: The LiDCOrapid and NICOM(r) hemodynamic monitors exhibit large mean differences indicating that they should not be considered clinically interchangeable. There is an unacceptable level of agreement (ATI>2) conferring an extreme risk of clinical misclassification with massive hemorrhage. This article is protected by copyright. All rights reserved.

AB - The ubiquitin ligase F-box and WD repeat domain-containing 7 (FBXW7) is responsible for degrading diverse oncoproteins and is considered a tumor suppressor in many human cancers. Inhibiting FBXW7 enhances the malignant potential of several cancers. In this study, we aimed to investigate the role of FBXW7 in cholangiocarcinoma. We found that FBXW7 expression was associated with clinicopathological outcomes in cholangiocarcinoma patients. Both disease-free and overall survival were significantly worse in the low-FBXW7 group than in the high-FBXW7 group (P = .001 and P < .001, respectively). Multivariate analysis with the Cox proportional hazards model indicated that FBXW7 was the most important independent prognostic factor for disease-free (P = .006) and overall (P = .0004) survival. We also showed that the two FBXW7 substrates, NOTCH1 and myeloid cell leukemia sequence 1 (MCL1), regulate cholangiocarcinoma progression. Depletion of FBXW7 resulted in NOTCH1 accumulation and increased cholangiocarcinoma cell migration and self-renewal. Interestingly, when cells were stimulated with cis-diamminedichloridoplatinum(II) (cisplatin), FBXW7 suppression induced MCL1 upregulation, which reduced the sensitivity of cholangiocarcinoma cells to apoptosis, indicating that FBXW7-mediated ubiquitylation is context-dependent. These results indicate that FBXW7 modulates the malignant potential of cholangiocarcinoma through independent regulation of NOTCH1 and MCL1. PMID- 30302869 TI - Involving young people in cyberbullying research: The implementation and evaluation of a rights-based approach. AB - BACKGROUND: Cyberbullying is an international Public Health concern. Efforts to understand and address it can be enhanced by involving young people. This paper describes a rights-based collaboration with young people in a qualitative exploration of cyberbullying. It describes the establishment, implementation and evaluation of a Young Person's Advisory Group as well as identifying the impact on the research process and the young people involved. METHODS: Sixteen postprimary school students met with researchers on five occasions in a youth centre. Sessions focused on building the young people's capacity to engage with the research, designing the qualitative study, interpreting study findings and evaluating the collaboration process. RESULTS: The Advisory Group highlighted a lack of understanding and appropriate action with regard to cyberbullying but believed that their involvement would ultimately help adults to understand their perspective. Evaluation findings indicate that members were supported to form as well as express their views on the design, conduct and interpretation of the research and that these views were acted upon by adult researchers. Their involvement helped to ensure that the research was relevant and reflective of the experiences, interests, values and norms of young people. CONCLUSION: Young people can contribute a unique perspective to the research process that is otherwise not accessible to adult researchers. The approach described in this study is a feasible and effective way of operationalizing young people's involvement in health research and could be adapted to explore other topics of relevance to young people. PMID- 30302870 TI - Substrate-Induced Self-Assembly of Cooperative Catalysts. AB - Dissipative self-assembly processes in nature rely on chemical fuels that activate proteins for assembly through the formation of a noncovalent complex. The catalytic activity of the assemblies causes fuel degradation, resulting in the formation of an assembly in a high-energy, out-of-equilibrium state. Herein, we apply this concept to a synthetic system and demonstrate that a substrate can induce the formation of vesicular assemblies, which act as cooperative catalysts for cleavage of the same substrate. PMID- 30302871 TI - Discovery and Elucidation of the Biosynthesis of Aspernidgulenes: Novel Polyenes from Aspergillus Nidulans by Using Serial Promoter Replacement. AB - Through serial promoter exchanges, we isolated several novel polyenes, the aspernidgulenes, from Aspergillus nidulans and uncovered their succinct biosynthetic pathway involving only four enzymes. An enoyl reductase (ER)-less highly reducing polyketide synthase (HR-PKS) putatively produces a 5,6-dihydro alpha-pyrone polyene, which undergoes bisepoxidation, epoxide ring opening, cyclization, and hydrolytic cleavage by three tailoring enzymes to generate aspernidgulene A1 and A2. Our findings demonstrate the prowess of fungal tailoring enzymes to transform a polyketide scaffold concisely and efficiently into complex structures. Moreover, comparison with citreoviridin and aurovertin biosynthesis suggests that methylation of the alpha-pyrone hydroxy group by methyltransferase (CtvB or AurB) is the branching point at which the biosynthesis of these two classes of compounds diverge. Therefore, scanning for the presence or absence of the gatekeeping alpha-pyrone methyltransferase gene in homologous clusters might be a potential way to classify the product bioinformatically as belonging to methylated alpha-pyrone polyenes or polyenes containing rings derived from the cyclization of the unmethylated 5,6-dihydro-alpha-pyrone, such as 2,3-dimethyl-gamma-lactone and oxabicyclo[2.2.1]heptane. PMID- 30302872 TI - Outcomes for patients with second primary malignancy after primary surgical treatment for early-stage squamous cell carcinoma of the oral cavity. AB - BACKGROUND: The purpose of our article was to describe a tertiary center's experience with patients with primarily surgically treated early-stage intraoral cancer with a second primary malignancy confirmed during follow-up. METHODS: A total of 183 patients were primarily surgically treated for oral cancer between 2000 and 2004. Among these, 24 patients (13.1% (24/183)) met inclusion criteria. RESULTS: There were 22 men (91.7%) and 2 women (8.3%) with a median age of 59.5 years. Patients with head and neck cancer with a second primary malignancy had significantly higher survival compared to nonhead and neck cancer with a second primary malignancy. Patients with head and neck cancer with second primary malignancy were diagnosed during the period of 14 to 45 months (median 29 months), whereas nonhead and neck cancer with second primary malignancy occurred in a period of 7 to 46 months (median 19 months). CONCLUSION: This study highlights the importance of optimizing screening strategies for second primary malignancies. In order to improve the survival of patients with head and neck squamous cell carcinoma (HNSCC), effective programs of screening and/or chemoprevention of second primary malignancies are essential. PMID- 30302873 TI - Prognostic role of epiregulin/amphiregulin expression in recurrent/metastatic head and neck cancer treated with cetuximab. AB - BACKGROUND: Cetuximab combined with chemoradiotherapy is the standard therapy for recurrent/metastatic head and neck squamous cell carcinoma (HNSCC). However, survival benefit is limited. The purpose of this study was to investigate the expression of epiregulin (EREG) and amphiregulin (AREG), as predictive prognostic markers for the efficacy of cetuximab combined with chemotherapy in R/M HNSCC. METHODS: We conducted a retrospective analysis of 37 patients diagnosed with R/M HNSCC. Tumor samples were analyzed for EREG and AREG mRNA gene expression, and clinical outcomes evaluated. RESULTS: Values of EREG and AREG were associated with significantly longer overall survival (OS) (P = .03 and P = .01, respectively), as well as progression-free survival (PFS) (P = .04 and P = .04, respectively). Multivariate analysis revealed that AREG expression was significantly associated with OS and PFS. CONCLUSIONS: Patients with recurrent/metastatic HNSCC with higher EREG and AREG gene expression appear to benefit more from cetuximab combined with chemoradiotherapy than those with lower expression. PMID- 30302874 TI - Rhodium-Catalyzed Enantioselective Defluorinative alpha-Arylation of Secondary Amides. AB - We exploited the reactivity of an electronically biased Michael acceptor to perform a defluorinative alpha-arylation reaction using a chiral diene(L*) rhodium catalyst. Through this methodology, we are able to obtain various secondary amides, containing a tertiary alpha-stereocenter and a beta,gamma unsaturated gem-difluoro olefin, with excellent enantioselectivities. This methodology addresses the limitations of the previously described alpha-arylation methods to construct stereo-labile tertiary alpha-stereocenters. Further investigation of the reaction via in situ 19 F NMR monitoring suggests that the formation of the product leads to the inhibition of the active rhodium catalyst. PMID- 30302875 TI - The Recovery Strengths Questionnaire for alcohol and drug use disorders. AB - INTRODUCTION AND AIMS: The Recovery Strengths Questionnaire (RSQ) is a 15-item self-report questionnaire that assesses an addicted individual's recovery strengths. This study aimed to validate the RSQ as a measure of recovery capital. DESIGN AND METHODS: As part of a larger study, 151 participants in addiction recovery groups from across the UK completed the RSQ. Participants also completed the Assessment of Recovery Capital questionnaire and provided some demographic information. RESULTS: The RSQ was found to be psychometrically sound, with high internal consistency and concurrent validity with the Assessment of Recovery Capital. RSQ scores were positively correlated with length of time in recovery and length of membership in recovery groups, and the scores could be used to discriminate between those in early and late recovery. Principal components analysis revealed a two-factor structure of recovery capital. These two factors were named 'within-group recovery strengths' and 'externally generated recovery strengths', and it was found that only the within-group factor scale (i.e. resources developed within recovery groups) predicted length of time in recovery and recovery groups. DISCUSSION AND CONCLUSIONS: These results highlight the important role that recovery groups can play in an individual's recovery, and they provide an alternative factor structure to the one-factor structure of the Assessment of Recovery Capital.

PMID- 30302877 TI - Psychosocial benefits of insulin pump therapy in children with diabetes type 1 and their families: The pumpkin multicenter randomized controlled trial. AB - OBJECTIVE: Continuous subcutaneous insulin infusion (CSII) is on the rise among pediatric patients with type 1 diabetes mellitus. Metabolic effects alone cannot explain this rising popularity. From the patient's perspective, the main benefits of CSII may be found in subjective psychosocial health outcomes (patient-reported outcomes [PRO]). SUBJECTS AND METHODS: In a multicenter open randomized controlled trial, children and adolescents aged 6 to16 years currently treated with multiple daily injections (MDI) were randomized 1:1, stratified by center, to either starting with CSII immediately after the baseline interview or to continuing MDI while waiting 6 months for transmission to CSII. The primary outcomes were patient-reported diabetes-specific health-related quality of life (DHRQOL) and diabetes burden of the main caregiver. Secondary outcomes were caregiver stress, fear of hypoglycemia, satisfaction with treatment, and HbA1c. RESULTS: Two-hundred and eleven patients were randomized between February 2011 and October 2014, and 186 caregivers and 170 patients were analyzed using the intention-to-treat principle for primary outcomes. Children 8 to 11 years in the CSII group reported improved DHRQOL at follow-up compared to MDI (median difference [MD] 9.5, 95% confidence interval [CI] 3.6-16.7, P = 0.004). There were no treatment differences in the adolescent age-group 12 to 16 years (MD 2.7; 95% CI -3.2-9.5; P = 0.353). The main caregivers of the CSII group reported a significant decline of overall diabetes burden at follow-up compared to the MDI group (MD 0; 95% CI -1-0; P = 0.029). Secondary PROs also were in favor of CSII. CONCLUSIONS: CSII has substantial psychosocial benefits. PROs demonstrate these benefits. Registered as NCT01338922 at clinicaltrials.gov.

PMID- 30302881 TI - Caudal and intravenous dexmedetomidine similarly prolong the duration of caudal analgesia in children: A randomized controlled trial. AB - BACKGROUND: Dexmedetomidine can prolong the duration of action of a local anesthetic agent, but the route of administration that is the most beneficial remains unclear. The purpose of this study was to compare the clinical effectiveness of caudal or intravenous dexmedetomidine administration on postoperative analgesia in children undergoing inguinal hernia repair given caudal levobupivacaine. METHODS: This was a prospective, randomized, double blinded, placebo-controlled trial. Ninety ASA I subjects, aged 2-5 year, undergoing unilateral inguinal hernia repair were enrolled. The children were randomized in a double-blind fashion to three groups. The L-Dcau group received 1 mL/kg of caudal 0.25% levobupivacaine plus 1 MUg/kg dexmedetomidine and IV 20 mL saline. The L-Div group received 1 mL/kg of caudal 0.25% levobupivacaine and IV 1 MUg/kg dexmedetomidine in 20 mL saline. The L group received 1 mL/kg of caudal 0.25% levobupivacaine and IV 20 mL saline. The primary outcome was the duration of analgesia, which was defined as the time from the caudal block to a Postoperative Pain Scale (CHIPPS) score >=4. Secondary outcomes were the number of patients requiring rescue analgesia, pain intensity, the incidence of emergence agitation, intraoperative hemodynamic variations, residual motor block, and adverse effects. RESULTS: The median duration of analgesia in the L-Dcau group was 14.2 hour compared to 6 hour in the L group with a median difference of 8.5 hour [95% CI (6.5, 10.5), P < 0.001]. The median duration of analgesia in the L-Div group was 12.4 hour compared to 6 hour in the L group with a median difference of 6.4 hour [95% CI (4, 8.5), P < 0.001]. Fewer patients in the L-Dcau and L-Div groups required rescue analgesia in the first 24 hour postoperatively compared to the L group, although there was no significant difference between the L-Dcau and L-Div groups for these outcomes. Both dexmedetomidine routes reduced the pain and the incidence of emergence agitation. No bradycardia, hypotension, or motor block was observed in any of the three groups. CONCLUSION: Caudal and IV dexmedetomidine similarly prolong the duration of analgesia produced by caudal levobupivacaine.

AB - BACKGROUND: Postoperative pain in children is often poorly managed at home, leading to slower functional recovery, poor oral intake, sleep disturbances, and behavioral changes. Panda is a smartphone application (app) designed to support parents in assessing their child's pain and managing medications. AIMS: The aim of this study was to evaluate the Panda app's usability and feasibility in hospital prior to testing the app at home. METHODS: The study comprised two phases. Phase I evaluated Panda's usability with nurses, parents, and adolescents using simulated scenarios. Usability was measured by task completion rate, user error rates, and the Computer Systems Usability Questionnaire. Phase II evaluated Panda's feasibility by observing parents/guardians of pediatric patients using the app on the postsurgical ward. Feasibility was measured using response frequency and delay following app notifications from an audit trail of app function, and parental satisfaction from an interview. Feedback was used to guide iterative app improvements. RESULTS: In Phase I, 13 nurses, 12 parents, and 5 adolescents evaluated the app. A total of 103 usability issues were identified, analyzed, and addressed. In Phase II, 29 parents responded to a total of 151 app notifications, with 84% responding within 1 hour in the final round of testing; 93% of participants reported the app was easy to use, and rated the app with a median [interquartile range] Computer Systems Usability Questionnaire score of 2 [1-4]. Significant barriers to use included lack of flexibility in the medication scheduling, low volume of alert sounds, and the extra time spent on medication safety checks. CONCLUSION: Panda's usability was improved and its feasibility demonstrated in the controlled hospital environment. The next step is to evaluate its feasibility for use at home. PMID- 30302883 TI - Autonomic cardiac regulation after general anesthesia in children. AB - BACKGROUND: General anesthesia dramatically decreases the activity of the autonomic nervous system. Most of the hypnotic agents used to induce anesthesia inhibit sympathetic cardiovascular regulation and baroreflex control in a dose dependent manner, lowering cardiac adaptability during the operation. The consequence of this effect in children during and after surgery has never been studied to date. AIM: The aim of this study was to follow the variations in autonomic cardiac indices in children younger than 8 years old after general anesthesia (6-24 hours) in programmed surgery. METHOD: A prospective descriptive monocentric study of 44 children under 8 years old who underwent scheduled surgery at our hospital center (Saint-Etienne University Hospital, France) was performed between June 1, 2016 and November 1, 2016. Heart rate variability was monitored for 24 hours using Holter-ECG devices and the resulting data were interpreted using linear and nonlinear analyses. RESULTS: Compared to baseline thresholds before surgery, all heart rate variability indices decreased dramatically during general anesthesia. After awakening, a slight reduction in sympathetic activity persisted 6 hours after surgery, but all measurements of sympathetic and parasympathetic activity had returned to baseline thresholds 12 hours after the operation. Twenty-four hours after surgery, some parameters had increased above the corresponding baseline levels. CONCLUSION: Autonomic nervous function normalizes rapidly (within 12 hours) in prepubertal children. This study indicates that general anesthesia does not seem to increase the long-term risk of autonomic dysfunction in these patients.

AB - BACKGROUND: An electronic review of unplanned day case admission rates in our hospital demonstrated an average annual rate for pediatric circumcision of 2%-3% in recent years with high levels of perioperative strong opiate use. This lay above target unplanned admission rates (<2%) set out by the Royal College of Anaesthetists for day case surgery. A targeted quality improvement initiative was undertaken to improve patient flow through the pediatric day case surgery unit for elective circumcision. Among the reasons for unplanned admission, factors modifiable by the anesthetist (pain, postoperative nausea and vomiting, somnolence) are significant contributors. METHODS: A prospective audit was undertaken over a 3-month period. Our practice was compared with evidence-based analgesic and antiemetic interventions in accordance the Association of Paediatric Anaesthetists of Great Britain and Ireland. Perioperative strong opiate administration rates occurred in 44% of cases. Four strategic interventions were selected based on quality of evidence, ease of implementation, and low cost: selection of higher concentration local anesthetic use for penile blocks, intravenous dexamethasone, and preoperative paracetamol combined with maximum dose nonsteroidal anti-inflammatory. RESULTS: The audit was duplicated a year later demonstrating a significant increase in application of these interventions with a parallel fall in strong opiate use from 44% to 9% and an unprecedented zero unplanned admission rate in our unit for 10 months in a row after implementation. CONCLUSION: Regular scrutiny of patient electronic data helps identify high impact areas for audit and intervention. Unplanned admission in pediatric day case surgery is an area amenable to such targeted intervention. PMID- 30302886 TI - Correcting for repeated outcome measures. PMID- 30302887 TI - A cluster of high psychological and somatic symptoms in children with idiopathic scoliosis predicts persistent pain and analgesic use 1 year after spine fusion. AB - BACKGROUND: Persistent postoperative pain is a significant problem for many children, particularly for those undergoing major surgery such as posterior spine fusion. More than two-thirds report persistent pain after spine fusion, yet factors that may contribute to poorer outcomes remain poorly understood. AIMS: This prospective, longitudinal study examined how psychologic and somatic symptoms cluster together in children aged 10-17 years with idiopathic scoliosis, and tested the hypothesis that a higher psychological and somatic symptom cluster would predict worse pain outcomes 1 year after fusion. METHODS: Otherwise healthy children with idiopathic scoliosis completed preoperative surveys measuring recent pain intensity, pain location(s), somatic symptom severity, painDETECT (neuropathic-type pain symptoms), pain interference, fatigue, depression, anxiety, and pain catastrophizing. Pain outcome data were collected during hospitalization, and at 1 year after surgery. RESULTS: Ninety-five children completed baseline surveys and a cluster analysis differentiated 28 (30%) with a high symptom profile that included; higher depression, fatigue, pain interference, catastrophizing, and painDETECT scores. High symptom cluster membership independently predicted higher pain interference at 1 year (beta 9.92 [95% CI 6.63, 13.2], P < 0.001). Furthermore, children in this high symptom cluster reported significantly higher pain intensity and painDETECT scores, and had a 50% higher probability of continued analgesic use at 1 year compared to those in the Low Symptom Cluster (95% CI 21.3-78.5, P = 0.001). CONCLUSION: Findings from this exploratory study suggest a need to comprehensively assess children with scoliosis for preoperative signs and symptoms that may indicate an underlying vulnerability for persistent pain. This, in turn may help guide a comprehensive perioperative treatment strategy to mitigate the potential for long term pain trajectories.

AB - Low-cost, efficient bifunctional electrocatalysts are needed to mediate the oxygen reduction and oxygen evolution reactions (ORR/OER) in Zn-air batteries. Such catalysts should offer binary active sites and an ability to transfer oxygen based species and electrons. A 3D catalyst, composed of nanoparticles of CoFe alloy embedded in N-doped carbon nanotubes tangled with reduced graphene oxide, was developed, which presents appreciable ORR/OER activity when applied in a Zn air battery. A high open-circuit voltage of 1.43 V, a stable discharge voltage of 1.22 V, a high energy efficiency of 60.1 %, and excellent stability after 1 600 cycles at 10 mA cm-2 are demonstrated. An all-solid-state battery had an outstanding lifetime and high cell efficiency even upon bending. In situ X-ray absorption spectroscopy revealed that OOH* and O* intermediates induce variations in the Fe-Fe and Co-Co bond lengths, respectively, suggesting that Fe and Co species are crucial to the ORR/OER processes.

AB - BACKGROUND: There have been arguments over the efficacy of elective unilateral central neck dissection (CND) in patients with papillary thyroid carcinoma (PTC) <1 cm who underwent hemithyroidectomy. This study was designed to investigate locoregional recurrence and postoperative complications related to elective unilateral CND for papillary thyroid microcarcinoma (PTMC). METHODS: Five hundred thirty-seven patients who underwent hemithyroidectomy, with or without CND for PTMC, were included. We compared locoregional recurrence and postoperative complication rates between 138 patients who underwent hemithyroidectomy only (CND group) and 399 patients who underwent hemithyroidectomy with elective unilateral CND (CND+ group). RESULTS: Recurrence was observed in 32 patients. Twenty-two patients with recurrence were in the CND+ group and 10 were in the CND- group. Recurrence rate was not significantly different between the 2 groups (P = .434). CONCLUSION: Concomitant unilateral elective CND did not enhance outcomes of hemithyroidectomy for the treatment of PTMC. PMID- 30302892 TI - CO2 embolus during transanal TME; thoughts on aetiology.

AB - MicroRNA (miRNA) expression is frequently deregulated in human disease, in contrast, disease-associated miRNA mutations are understudied. We developed Annotative Database of miRNA Elements, ADmiRE, which combines multiple existing and new biological annotations to aid prioritization of causal miRNA variation. We annotated 10,206 mature (3,257 within seed region) miRNA variants from multiple large sequencing datasets including gnomAD (15,496 genomes; 123,136 exomes). The pattern of miRNA variation closely resembles protein-coding exonic regions, with no difference between intragenic and intergenic miRNAs (P = 0.56), and high confidence miRNAs demonstrate higher sequence constraint (P < 0.001). Conservation analysis across 100 vertebrates identified 765 highly conserved miRNAs that also have limited genetic variation in gnomAD. We applied ADmiRE to the TCGA PanCancerAtlas WES dataset containing over 10,000 individuals across 33 adult cancers and annotated 1,267 germline (rare in gnomAD) and 1,492 somatic miRNA variants. Several miRNA families with deregulated gene expression in cancer have low levels of both somatic and germline variants, e.g., let-7 and miR-10. In addition to known somatic miR-142 mutations in hematologic cancers, we describe novel somatic miR-21 mutations in esophageal cancers impacting downstream miRNA targets. Through the development of ADmiRE, we present a framework for annotation and prioritization of miRNA variation in disease datasets.

AB - Annualization of woody perennials has the potential to revolutionize the breeding and production of fruit crops and rapidly improve horticultural species. Kiwifruit (Actinidia chinensis) is a recently domesticated fruit crop with a short history of breeding and tremendous potential for improvement. Previously, multiple kiwifruit CENTRORADIALIS (CEN)-like genes have been identified as potential repressors of flowering. In this study, CRISPR/Cas9- mediated manipulation enabled functional analysis of kiwifruit CEN-like genes AcCEN4 and AcCEN. Mutation of these genes transformed a climbing woody perennial, which develops axillary inflorescences after many years of juvenility, into a compact plant with rapid terminal flower and fruit development. The number of affected genes and alleles and severity of detected mutations correlated with the precocity and change in plant stature, suggesting that a bi-allelic mutation of either AcCEN4 or AcCEN may be sufficient for early flowering, whereas mutations affecting both genes further contributed to precocity and enhanced the compact growth habit.

AB - Europium ion (Eu2+ )-doped phosphors exhibit adjustable photoluminescence due to the sensitivity of their luminescence to the local environment. It is of great significance to adjust the luminescence of Eu2+ by changing their local environment in the host. In this work, we investigated the effect of strontium/barium (Sr:Ba) ratio on the structure and luminescence properties of Sr2-x Bax MgAl22 O36 :Eu2+ phosphors. Our investigation indicates that with the decrease of Sr:Ba ratio, the matrix lattice gradually expands and the peak wavelength for the luminescence of Eu2+ presents an obvious blue shift. The occupancy of Eu2+ was analyzed and the reason for the blue shift was explained. Thermal stability for the luminescence of Eu2+ can also be adjusted by changing the Sr:Ba ratio. This work has a positive effect on the regulation of the emission of phosphors and the improvement of thermal stability, which will promote the application of Sr2-x Bax MgAl22 O36 :Eu2+ phosphors in the field of white light emitting diodes.

AB - OBJECTIVE: To determine if there is an association between the concentration of symmetric dimethylarginine (SDMA) in dogs measured at the time of admission with the severity of critical illness and short-term mortality. DESIGN: This prospective observational study recruited critically ill dogs with heterogeneous diagnoses and then classified their disease severity using the acute patient physiologic and laboratory evaluation complete score as having either a good (<30) or poor (>=30) prognosis. SETTING: This study was conducted at Ross University Veterinary Clinic between January and November 2015. ANIMALS: After exclusion of dogs diagnosed with acute kidney injury, 22 critically ill dogs and 7 control dogs were included in the study. INTERVENTIONS: Each dog was assigned an acute patient physiologic and laboratory evaluation score calculated by the summation of individual scores allocated to selected clinical, focused assessment by sonography, hematological, and biochemistry results. Plasma SDMA concentrations were measured for all dogs at the time of admission. MEASUREMENT AND MAIN RESULTS: There was no difference identified in SDMA concentrations between dogs with a severe category of disease as compared to mild to moderate category, or critically ill dogs compared to control dogs. There was also no difference identified in SDMA concentrations in survivors as compared to nonsurvivors. Similarly, SDMA concentration was not higher in nonsurvivors than in survivors (P = 0.968). In this population of dogs, SDMA was not a prognostic indicator. CONCLUSION: Further work may be warranted in specific populations of animals but based upon this work SDMA is likely of little relevance. PMID- 30302897 TI - Thermoluminescence properties of La3+ , Gd3+ ,Dy3+ and Ho3+ co-doped MgAl2 Si2 O8 :Mn4. AB - Thermoluminescence properties of Mn4+ -doped and La3+ , Gd3+ , Dy3+ and Ho3+ co doped MgAl2 Si2 O8 host phosphors were investigated in detailed and reported for the first time. The phosphors were exposed to beta- and alpha-irradiation and the glow curves appeared at 260-262 +/- 2 degrees C and 245-252 +/- 2 degrees C, respectively. Thermoluminescence analysis show that the main glow peaks actually consisted of three distinct peaks (P1 , P2 and P3 ). In addition, all the phosphors had a main peak, and many satellite peaks also appeared up to 200 degrees C. Moreover, it was observed that La3+ , Gd3+ , Dy3+ and Ho3+ dopants in MgAl2 Si2 O8 Mn4+ phosphor can change the thermoluminescence peak intensities, but they did not cause any new glow peak. In addition, when alpha-irradiation was used, the glow peaks were shift to a lower temperature region. Kinetic parameters of P1 , P2 and P3 were calculated, and it was found that P1 and P3 had first order kinetics and P2 had general-order kinetic parameters. In addition, it was found that when the easy and convenient annealing procedure was applied to the phosphorus, the thermoluminescence signal was measured as stable over many repetitions. The dose sensitivity, reproducibility and fading features of the powdered phosphors were investigated and computerized glow curve deconvolution analysis was also performed. Results showed that thermoluminescence properties of these materials were good but the fading reliabilities were poor and therefore the sintered or single crystal forms should be preferred for their better fading properties. PMID- 30302898 TI - Comparison of radiopacity of current restorative CAD/CAM blocks with digital radiography. AB - OBJECTIVE: While the radiopacity of restorative material affects the radiographic diagnosis of the teeth, there is no data about the radiopacity of current restorative computer-aided design (CAD)/computer-aided manufacturing (CAM) materials. Therefore, the present study compared the radiopacity values of current restorative CAD/CAM blocks to facilitate the material choice within such a wide variety of materials. MATERIALS AND METHODS: Specimens were prepared from 13 different restorative CAD/CAM blocks to compare with enamel and dentin. The specimens placed on the occlusal phosphor plate were imaged with aluminum step wedge and tooth section. The radiopacity values were calculated using the Image J program. The radiopacity values of the specimens were converted to mmAl values with the Curve Expert 1.4 program. RESULTS: The difference between the radiopacity values of dentin and e.max CAD was not significant, however, they exhibited a significant difference from the other 14 groups (P < .05). Enamel and Obsidien, Suprinity, and Celtra Duo had greater radiopacity values with significant differences from the other 12 materials whereas the difference within these groups was not significant (P > .05). CONCLUSIONS: The evaluated restorative CAD/CAM materials have significantly different radiopacity values. Among these permanent restoration blocks, the highest radiopacity value was observed in Celtra Duo, the lowest in Block HC. CLINICAL SIGNIFICANCE: Cerasmart, Lava Ultimate, Obsidian, Vita Suprinity, Celtra Duo Blocks have adequate radiopacity for inlay, onlay and crown restorations, however, the use of Vita Enamic, Vita Mark II, GC LRF blocks and the others which have lower radiopacity value than dentin for the same kind of restorations depend on the radiopacity of the luting cement for the purpose of recurrent caries detection. PMID- 30302899 TI - Schaaf-Yang syndrome overview: Report of 78 individuals. AB - Schaaf-Yang Syndrome (SYS) is a genetic disorder caused by truncating pathogenic variants in the paternal allele of the maternally imprinted, paternally expressed gene MAGEL2, located in the Prader-Willi critical region 15q11-15q13. SYS is a neurodevelopmental disorder that has clinical overlap with Prader-Willi Syndrome in the initial stages of life but becomes increasingly distinct throughout childhood and adolescence. Here, we describe the phenotype of an international cohort of 78 patients with nonsense or frameshift mutations in MAGEL2. This cohort includes 43 individuals that have been reported previously, as well as 35 newly identified individuals with confirmed pathogenic genetic variants. We emphasize that intellectual disability/developmental delay, autism spectrum disorder, neonatal hypotonia, infantile feeding problems, and distal joint contractures are the most consistently shared features of patients with SYS. Our results also indicate that there is a marked prevalence of infantile respiratory distress, gastroesophageal reflux, chronic constipation, skeletal abnormalities, sleep apnea, and temperature instability. While there are many shared features, patients with SYS are characterized by a wide phenotypic spectrum, including a variable degree of intellectual disability, language development, and motor milestones. Our results indicate that the variation in phenotypic severity may depend on the specific location of the truncating mutation, suggestive of a genotype-phenotype association. This evidence may be useful in both prenatal and pediatric genetic counseling. PMID- 30302900 TI - Diploid/triploid mixoploidy: A consequence of asymmetric zygotic segregation of parental genomes. AB - Triploidy is the presence of an extra haploid set of chromosomes and can exist in complete or mosaic form. The extra haploid set of chromosomes in triploid cells can be of maternal or paternal origin. Diploid/triploid mixoploidy is a unique form of triploid mosaicism that requires the aberrant segregation of entire parental genomes into distinct blastomere lineages (heterogoneic cell division) at the earliest zygotic divisions. Here we report on eight cases of diploid/triploid mixoploidy from our institution and conduct a comprehensive review of the literature. The parental origin of the extra set of chromosomes was determined in two cases; and, based on phenotypic evidence we propose the parental origin in the other cases. One case with complex mixoploidy appears to have a digynic origin in addition to the involvement of two different sperm. Of our eight cases, only one resulted in the birth of a live healthy child. The other pregnancies ended in miscarriage, elective termination of pregnancy, intrauterine fetal demise or neonatal death. A review of the literature and the results of our cases show that a preponderance of recognized cases of diploid/triploid mixoploidy has a digynic origin. PMID- 30302901 TI - Intralesional pentoxifylline injection in localized alopecia areata. AB - BACKGROUND: Alopecia areata (AA) is a common non-scarring autoimmune disease that affects hair-bearing areas. A variety of therapeutic options has been used for treating this disease such as corticosteroids, minoxidil, methotrexate, cyclosporine, and azathioprine. Intralesional triamcinolone acetonide (TRA) injection is considered the first-line treatment in localized alopecia areata involving <50% of the scalp; however, intralesional steroid injections are associated with a variety of side effects. OBJECTIVE: The aim of this study was to evaluate the efficacy of pentoxifylline (PTX) vs triamcinolone acetonide intralesional in localized AA. PATIENTS AND METHODS: The sample included 75 patients (47 males and 28 females) aged 18-55 years, diagnosed as localized alopecia areata. The patients were treated by intralesional injection every three weeks up to five sessions. The patients were classified into three groups according to the used therapeutic modality. Group A: 25 patients treated by intralesional injection of TRA. Group B: 25 patients treated by combined intralesional injection of TRA and PTX injection. Group C: 25 patients treated by intralesional PTX injection. RESULTS: Both PTX and TRA intralesional injections were effective in the treatment of AA, but there was a statistically significant difference regarding the response to treatment between the three study groups (P value = 0.01). The highest response was reported in combined drug usage (TRA & PTX) followed by PTX alone and then TRA alone (72.0%, 60.0%, and 32.0%, respectively). CONCLUSION: Pentoxifylline intralesional injection is effective, easy to perform with little side effects for the treatment of localized alopecia areata. PMID- 30302902 TI - Short Panicle 3 controls panicle architecture by upregulating APO2/RFL and increasing cytokinin content in rice. AB - Inflorescence architecture is a major determinant of spikelet numbers per panicle, a key component of grain yield in rice. In this study, Short Panicle 3 (SP3) was identified from a short panicle 3 (sp3) mutant in which T-DNA was inserted in the promoter of SP3, resulting in a knockdown mutation. SP3 encodes a DNA binding with one finger (Dof) transcriptional activator. Quantitative real time (qRT)-PCR and RNA in situ hybridization assays confirmed that SP3 is preferentially expressed in the young rice inflorescence, specifically in the branch primordial regions. SP3 acts as a negative regulator of inflorescence meristem abortion by upregulating APO2/RFL. SP3 both up- and down-regulates expression of genes involved in cytokinin biosynthesis and catabolism, respectively. Consequently, cytokinin concentrations are decreased in young sp3 panicles, thereby leading to small panicles having fewer branches and spikelets. Our findings support a model in which SP3 regulates panicle architecture by modulating cytokinin homeostasis. Potential applications to rice breeding, through gene-editing of the SP3 promoter are assessed. PMID- 30302903 TI - Conventional and quantitative MRI in a novel feline model of demyelination and endogenous remyelination. AB - BACKGROUND: The feeding of irradiated food to healthy adult cats results in widespread, noninflammatory demyelination of the central nervous system (CNS); a return to a normal diet results in endogenous remyelination with functional recovery. This recently discovered, reversible disease might provide a compelling clinical neuroimaging model system for the development and testing of myelin directed MRI methods as well as future remyelination therapies. PURPOSE: Identify the noninvasive imaging characteristics of this new disease model and determine whether it features measurable changes on conventional and quantitative MRI. STUDY TYPE: Pilot study. ANIMAL MODEL: Ten adult cats at various stages of demyelinating disease induced by an irradiated diet (35-55 kGy), and during recovery following a return to a normal diet. FIELD STRENGTH/SEQUENCE: Conventional (T2 -weighted) and quantitative (diffusion tensor, magnetization transfer) at 3T. ASSESSMENT: MRI of the brain, optic nerves, and cervical spinal cord; a subset of diseased cats was euthanized for comparative histopathology. STATISTICAL TESTS: Descriptive statistics. RESULTS: Disease produced T2 prolongation, progressing from patchy to diffuse throughout most of the cerebral white matter (eventually involving U-fibers) and spinal cord (primarily dorsal columns, reminiscent of subacute combined degeneration but without evidence of B12 deficiency). Magnetization transfer parameters decreased by 50-53% in cerebral white matter and by 25-30% in optic nerves and spinal cord dorsal columns. Fractional diffusion anisotropy decreased by up to 20% in pyramidal tracts, primarily driven by increased radial diffusivity consistent with axon preservation. Histopathology showed scattered myelin vacuolation of major white matter tracts as well as many thin myelin sheaths consistent with remyelination in the recovery phase, which was detectable on magnetization transfer imaging. DATA CONCLUSION: Feline irradiated diet-induced demyelination features noninvasively imageable and quantifiable demyelination and remyelination of the CNS. It is therefore a compelling clinical neuroimaging model system. LEVEL OF EVIDENCE: 4 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2018. PMID- 30302904 TI - Sulforaphane Normalizes Intestinal Flora and Enhances Gut Barrier in Mice with BBN-Induced Bladder Cancer. AB - SCOPE: Gut microbiota imbalance, inflammation, and gut barrier deficiency play an important role in carcinogenesis. Sulforaphane (SFN), an isothiocyanate found in cruciferous vegetables, has been proven to be highly effective in inhibiting cancer. The objective of this study is to investigate the potential roles of the gut microbiota in the inhibition of BBN-induced bladder cancer by SFN. METHODS AND RESULTS: N-butyl-N-(4-hydroxybutyl)-nitrosamine is used to induce bladder cancer in male C57BL/6 mice, with or without SFN for 23 weeks. SFN ameliorates the histological changes characteristic of bladder cancer, resulting in fewer submucosal capillaries. SFN normalizes gut microbiota dysbiosis in mice with BBN induced bladder cancer with a significant increase in Bacteroides fragilis and Clostridium cluster I. SFN also increases butyric acid levels in the mouse colon, and repairs the injury to the mucosal epithelium of the colon and cecum through the upregulation of the expression of tight junction proteins and GLP2. SFN greatly decreases the release of cytokines (IL-6) and secretory immunoglobulin A in the mice with bladder cancer. CONCLUSION: These results suggest that SFN protects against chemical-induced bladder cancer through normalizing the composition of gut microbiota and repairing the physiological destruction of the gut barrier, as well as decreasing inflammation and the immune response. PMID- 30302905 TI - Dysregulated homeostatic pathways in sarcopenia among frail older adults. AB - Sarcopenia, a core feature of the physical frailty syndrome, is characterized by multisystem physiological dysregulation. No study has explored qualitatively the hierarchical network of relationships among different dysregulated pathways involved in the pathogenesis of sarcopenia. We used 40 blood biomarkers belonging to community-dwelling prefrail and frail older persons to derive measures of multiple physiological pathways, and structural equation modeling to generate path network models of the multisystem physiological dysregulations associated with muscle mass and function (MMF). Insulin-leptin signaling and energy regulation, anabolic sex steroid regulation (testosterone, leptin), and tissue oxygenation (hemoglobin, red cell count) appear to be primary mediating factors exerting direct influences on MMF. There was additionally secondary mediatory involvement of myocyte- and adipocyte-derived cytokines, hypothalamic pituitary adrenal (HPA) stress hormones (cortisol, DHEAS), glomerular function, and immune cell regulatory and inflammatory cytokines and glycoproteins. We conclude that within a hierarchical network of multisystem physiological dysregulations in sarcopenia, dysregulated anabolic and catabolic pathways via sex steroids and insulin-leptin dual signaling and tissue hypoxemia are primary physiological dysregulations responsible for sarcopenia and frailty. PMID- 30302906 TI - Emphysematous gastritis in a cat. AB - OBJECTIVE: To describe the presentation, diagnosis, treatment, and outcome of a case of emphysematous gastritis (EG) in a cat. CASE SERIES SUMMARY: A 15-year-old female neutered domestic short-hair cat presented for a 4-month history of weight loss and intermittent vomiting. Clinicopathologic and imaging findings suggested an underlying primary gastrointestinal (GI) disease, as well as possible hepatobiliary disease. Two days following exploratory laparotomy to obtain GI and liver biopsies, the patient became septic and intracellular bacteria were present on cytology of peritoneal effusion. On radiographs, the stomach was markedly distended with fluid and contained a thin gas opacity surrounding the stomach wall. The patient was taken back to surgery to identify a source of sepsis. At surgery, the patient's stomach was firm and emphysematous on palpation but grossly appeared normal. There were no signs of dehiscence of the previous biopsy sites. Stomach biopsy confirmed the presence of intralesional Gram-positive rods, consistent with microbial EG, and a light growth of a Clostridium sp. was cultured from abdominal fluid, consistent with clostridial peritonitis. During a third surgery for suspected septic peritonitis, a jejunostomy tube was placed for postgastric enteral feeding. The patient ultimately survived to discharge and is clinically stable 10 months later. NEW/UNIQUE INFORMATION PROVIDED: EG is a rare but potentially fatal clinical entity in the human and veterinary literature with only 1 other case reported in cats. Though clostridial organisms have been reported in EG in people, this is the first implication of EG secondary to a Clostridium sp. in the cat. This is also the first report to document the use of a jejunostomy tube for postgastric enteral nutrition to treat EG in the veterinary literature. PMID- 30302907 TI - Characteristics of and current practice patterns of pacing for high-degree atrioventricular block after transcatheter aortic valve implantation in comparison to surgical aortic valve replacement. AB - OBJECTIVE: We aimed to investigate the current practice patterns of permanent pacing, especially the timing of implantation, for high-degree AV block (HDAVB) following transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR). BACKGROUND: Comparative data regarding current practice patterns of permanent pacing for HDAVB between TAVI and SAVR is limited. METHODS: Using the National Inpatient Sample database, we identified patients who underwent TAVI or SAVR between 2012 and 2014. The incidence of HDAVB, the rate of permanent pacemaker implantation, and the timing of implantations were compared between TAVI and SAVR groups. RESULTS: We identified 33 690 and 202 110 patients who underwent TAVI and SAVR, respectively. HDAVB occurred in 3480 patients (10.3%) in the TAVI group and 11 405 patients (5.6%) in the SAVR group (P < 0.001). Among the patients who developed HDAVB, patients in the TAVI group were more likely to undergo permanent pacemaker implantation than those in the SAVR group (74.1% vs 64.7%; P < 0.001). The median interval from TAVI to pacemaker implantation was 2 days (interquartile range 1-3 days) vs 5 days (interquartile range 3-7 days) from SAVR to pacemaker implantation (P < 0.001). Among the patients who developed HDAVB, TAVI was associated with higher rates of permanent pacemaker implantation after adjusting for other comorbidities (odds ratio 1.41:95% confidence interval 1.13-1.77; P = 0.003). CONCLUSIONS: HDAVB occurred more commonly after TAVI compared to SAVR. HDAVB after TAVI compared to SAVR was associated with a higher rate of permanent pacemaker implantation at an earlier timing from the index procedure.

AB - Application of nanostructured silicon (nSi) is significantly retarded by challenges in the production of affordable nSi. We herein report a high-yield (ca. 100 %) and low-energy (2 kWh Kg-nSi-1 ) nanostructuring of industrial microsized silicon (mSi) through a closed-loop electrochemical Mg alloying/dealloying in molten MgCl2 /NaCl/KCl at 773 K. The resulting nSi unexpectedly shows a salt-unwetted character, allowing an automatic separation from the melts. Thus water washing and accompanying oxidation of the nSi can be avoided. The final product has a nanoporous structure and comprises Si nanorods (ca. 30 nm in diameter) with an ultrathin oxide coating. It can be used for Li storage giving a combination of high initial coulombic efficiency, high specific capacity, and long cycling stability. This nanostructuring process consumes very few chemicals except for the mSi and produces almost zero waste. PMID- 30302910 TI - High false positive rate of white blood cells in urine samples of pregnant women may be caused by epithelial cells being misclassified by the sysmex UF-1000i urine flow cytometer. AB - BACKGROUND: The UF-1000i has been widely used in screening urinary sediments. However, the interference factor of the UF-1000i in the screening urinary sediments of pregnant women has not been reported. The aim of the study was to demonstrate that epithelial cells (ECs) cause a high false positive rate of white blood cells (WBCs) by the UF-1000i in pregnant women. METHODS: Urine samples were collected from 207 pregnant women. All samples were measured by the UF-1000i and a microscopic method. RESULTS: The areas under the curve (AUC) for WBC and EC counts were 0.837 (95% CI, 0.773-0.901) and 0.844 (95% CI, 0.785-0.903), respectively. The positive rates of the WBC and EC were 73.43% and 37.20%, respectively, by the UF-1000i, and they were 19.32% and 72.95% by the microscopic method. The positive predictive value, negative predictive value, false positive rates, and false negative rates by the UF-1000i were for WBC 25.66%, 98.18%, 74.34%, and 1.82%, respectively, and for EC they were 96.1%, 40.77%, 3.9%, and 59.23%, respectively. The coefficient of correlation R value was 0.503 (P < 0.01) between WBC by UF-1000i and EC by the microscopic method in WBC false positive samples. CONCLUSIONS: EC could be an interference factor for the UF-1000i in screening urinary WBC of pregnant women, and the high false positive rate for WBC may be caused by ECs being misclassified as WBCs by the UF-1000i. PMID- 30302909 TI - Five-year success rate of resin-bonded fixed partial dentures: A systematic review. AB - OBJECTIVES: To assess and compare the 5-year success rate of resin-bonded fixed partial dentures (RBFPDs) fabricated from different materials. METHODS: An electronic search on 3 databases from January 1965 to March of 2017 was done for human randomized clinical trials (RCTs), and prospective and retrospective cohort studies. The key words used in the search were: Bridge OR bridges OR fixed partial OR fixed dental AND resin bonded OR Maryland OR ceramic bonded. Quality assessment was done using the Newcastle-Ottawa scale. Success was defined as the RBFPDs remaining in situ and not having experienced debonding, biological failures, or mechanical failures at the examination visit. RESULTS: Meta analyses of the included studies showed an estimated 5-year success rate of 88.18% for the metal framework RBFPDs and 84.41% for the nonmetal framework RBFPDs. The estimated 5-year success rate for each nonmetal material category was 92.07% for zirconia, 94.26% for In-Ceram alumina, and 84.83% for fiber-reinforced composite. The failure rate was not statistically significant among the single, double, and multiple retainers RBFPDs (P > .05). Technical complications were the main reason for failures. CONCLUSION: The 5-year clinical performance of RBFPDs is similar to the performance of conventional fixed partial dentures (FPDs) and implant supported crowns. CLINICAL SIGNIFICANCE: Clinicians should consider using RBFPDs more often because their clinical performance is similar to the performance of conventional FPDs and implant-supported crowns. PMID- 30302911 TI - Mitochondrial Deformation During the Cardiac Mechanical Cycle. AB - Cardiomyocytes both cause and experience continual cyclic deformation. The exact effects of this deformation on the properties of intracellular organelles are not well characterized, although they are likely to be relevant for cardiomyocyte responses to active and passive changes in their mechanical environment. In the present study we provide three-dimensional ultrastructural evidence for mechanically induced mitochondrial deformation in rabbit ventricular cardiomyocytes over a range of sarcomere lengths representing myocardial tissue stretch, an unloaded "slack" state, and contracture. We also show structural indications for interaction of mitochondria with one another, as well as with other intracellular elements such as microtubules, sarcoplasmic reticulum and T tubules. The data presented here help to contextualize recent reports on the mechanosensitivity and cell-wide connectivity of the mitochondrial network and provide a structural framework that may aide interpretation of mechanically regulated molecular signaling in cardiac cells.

AB - An adaptive temperature-based replica-exchange simulation of a peptide extracted from the Ebola virus nucleoprotein containing a polyproline sequence motif is reported. The simulation results of applying the CHARMM36m force field with a generalized Born solvent model is presented. Conformational heterogeneity is described by potentials of mean force (PMFs) for a set of reaction coordinates that define the topological fold space. Starting from an extended backbone conformation of the peptide observed in an X-ray crystallographic assembly with the Ebola virus protein VP30, the PMFs report a conformational landscape populated by chain excursions to collapsed states with limited transitions to either an extended fold or a canonical polyproline type II helix. Clustering of the conformations and applying an elastic network interpolation model yield a multistep pathway of conformational selection that minimizes the net transition state cost from the population hub to the bound state. Related difference between the pathway endpoints taken from the PMFs reveal a significant free-energy penalty in reaching a population shift. To evaluate sequence fitness of the Ebola virus peptide in generating probability distributions, two human sequence variants are modeled and are found to produce profiles that show extensive deviations, thus suggesting either dissimilar binding mechanisms or the lack of recognition by VP30.

PMID- 30302914 TI - Application of coordination agent in high-speed counter-current chromatography for the preparative separation and isolation ginkgolic acids from the sarcotesta of Ginkgo biloba L. AB - An efficient coordination high-speed counter-current chromatography method for the preparative separation of ginkgolic acids from the sarcotesta of Ginkgo biloba L was developed. The type, concentration, and mechanism of the coordination agent were investigated. Following the use of four types of metal salts including silver nitrate, copper chloride, ferric chloride, and aluminium nitrate, n-heptane/ethyl acetate/methanol/acetic acid 5:4:1:1, v/v with 0.20 mol/L silver nitrate as the coordination agent was chosen as the optimum two phase solvent system. Five main ginkgolic acids including C13:0, C15:0, C15:1, C17:1, and C17:2 were successfully separated with purities greater than 98%. The sample loading was 500 mg, the flow-rate was 2.0 mL/min, rotation speed was 800 rpm and temperature was 20 degrees C. The structures of the separated ginkgolic acids were identified by comparison with standard samples and electrospray ionization mass spectrometry. The introduction of coordination chemistry in high speed counter-current chromatography is novel and effective for the preparative separation and isolation of ginkgolic acids from the sarcotesta of Ginkgo biloba L and could also be applied to separate compounds which form coordination bonds in other complex natural products. PMID- 30302915 TI - The Impact of Autonomy-Framed and Control-Framed Implementation Intentions on Snacking Behaviour: The Moderating Effect of Eating Self-Efficacy. AB - BACKGROUND: Autonomy-supportive implementation intention exercises have been shown to facilitate goal-directed behaviour (Koestner et al., ). The current study explored whether eating self-efficacy moderated the impact of autonomy framed versus control-framed implementation intentions to reduce high-calorie snack intake. METHODS: The study employed a randomised prospective design, involving two waves of data collection conducted in 2016. At Time 1, UK participants (N = 300) completed an online questionnaire which asked them to report their snacking behaviour over the previous 7 days. Participants were subsequently asked to form either an autonomy-framed implementation intention or a control-framed implementation intention. Seven days later, participants reported their consumption of high-calorie snacks and completed a measure of eating self-efficacy. RESULTS: Hierarchical multiple regression analysis revealed that eating self-efficacy moderated the effects of implementation intention framing. Autonomy-framed implementation intentions had a greater impact on the avoidance of snacking for high eating self-efficacy participants than did control framed implementation intentions. In contrast, for low eating self-efficacy participants, control-framed implementation intentions had more impact than did autonomy-framed implementation intentions. CONCLUSIONS: The results suggest that if implementation intentions to promote healthy diet are to be effective, the role of eating self-efficacy should be considered, and the design of interventions adapted accordingly. PMID- 30302916 TI - Evaluation of Mental Health First Aid skills in an Australian university population. AB - AIM: University students have high rates of mental health problems; however, most delay or fail to seek help altogether. Tertiary settings can offer educational and social programmes to increase mental health awareness and in turn increase the number of students seeking help for their problems. This study aimed to explore students' and staffs' knowledge of mental health issues, confidence to intervene and application of skills following Mental Health First Aid (MHFA) training. METHODS: Students and staff at an Australian university who had completed MHFA training in the previous 24 months were invited to complete a validated online questionnaire. RESULTS: Of the 566 eligible participants, 107 (19%) completed the questionnaire. The majority (65%) had applied their skills to someone in need, with the highest number applying it to students. Notably, of those who had applied their skills 23 participants (33%) had applied them in a crisis situation, the most common being panic attacks followed by suicidal thoughts. Although most (98%) applied their skills in a face-to-face capacity, 53% also reported assisting someone via electronic mediums and social media. The mean score for the literacy test was considered high, 12/16 (SD = 1.7) for students and 13/16 (SD = 2.5) for staff. The majority (94%) reported more confidence in providing support following training. CONCLUSION: This study demonstrated that MHFA training on a university campus is associated with a high level of knowledge, confidence to intervene and apply MHFA skills to assist a student or friend in need, potentially impacting their long-term health outcomes and future professional careers.

AB - AIM: The association between bipolar disorder and creativity may be related to symptoms of the disorder itself or personality traits present before the onset. To further explore the relationship between creativity and clinical risk for bipolar disorder, creativity among individuals with a history of depressive disorder and varying risk for future (hypo-)manic episodes was assessed and compared. METHODS: Thirty-eight participants completed the diagnostic process, including Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) Diagnosis, Hamilton Depression Scale and Young Mania Rating Scale. The early detection tools Bipolar Prodrome Symptom Interview and Scale-Prospective (BPSS-P), Early Phase Inventory for Bipolar Disorders (EPIbipolar) and bipolar-at-risk-(BAR) criteria were used to assign participants into different at-risk groups. Assessment of creativity included Barron-Welsh Art Scale (BWAS) and Creative Achievement Questionnaire (CAQ). Scores were compared between low- and high-risk groups for the development of bipolar disorder. RESULTS: Participants meeting BAR criteria scored significantly higher on the BWAS than the non-BAR group (P = 0.03). EPIbipolar groups did not differ significantly in creativity scores. Participants with mood swings, especially when associated with increased activity and euphoric features, had significantly higher BWAS scores compared to individuals without mood swings (P = 0.04). Sleep disturbances, substance abuse, anxiety, ADHD and behavioural disturbances in childhood or adolescence had no effect on creativity level or achievement scores. Generalisability was reduced by small sample size and inclusion of depressive participants only considered at-risk for bipolar disorder. CONCLUSIONS: There is evidence of increased creativity, but not of higher creative achievements, in persons at-risk of bipolar disorder. Mood swings are strongly associated with creativity.

AB - Delay-and-sum (DAS) is one of the most common algorithms used to construct the photoacoustic images due to its low complexity. However, it results in images with high sidelobes and low resolution. Delay-and-standard-deviation (DASD) weighting factor can improve the contrast of the images compared to DAS. However, it still suffers from high sidelobes. In this work, a new weighting factor, named delay-multiply-and-standard-deviation (DMASD) is introduced to enhance the contrast of the reconstructed images compared to other mentioned methods. In the proposed method, the standard deviation of the mutual multiplied delayed signals are calculated, normalized and multiplied to DAS beamformed data. The results show that DMASD improves the signal-to-noise-ratio about 19.29 dB and 7.3 dB compared to DAS and DASD, respectively, for invivo imaging of the sentinel lymph node. Moreover, the contrast-ratio is improve by the DMASD about 23.61 dB and 10.81 dB compared to DAS and DASD, respectively. This article is protected by copyright. All rights reserved.

AB - The metabolic abnormalities affecting bone in the setting of chronic kidney disease (CKD) are complex with overlapping and interacting aetiologies and have challenging diagnostic and management strategies. Disturbances in calcium, phosphate, fibroblast growth factor 23, parathyroid hormone concentrations and vitamin D deficiency are commonly encountered and contribute to the clinical syndromes of bone disorders in CKD, including hyperparathyroidism, osteomalacia, osteoporosis and adynamic bone disease. Mineral and bone abnormalities may also persist or arise de novo post-renal transplantation. The Kidney Disease Improving Global Outcomes organisation describes these mineral metabolism derangements and skeletal abnormalities as 'CKD Mineral and Bone Disorder'. Patients with this disorder have an increased risk of fracture, cardiovascular events and overall increased mortality. In light of the recently updated 2017 guidelines from the Kidney Disease Improving Global Outcomes, we present a clinical case-based discussion to highlight the complexities of investigating and managing the bone health of patients with CKD with a focus on these updates.

AB - OBJECTIVE: To evaluate the role of intravenous fluid volume and electrolyte supplementation on the development of postoperative reflux (POR) in horses undergoing celiotomy for colic. DESIGN: Case-control study spanning 2004-2012 for horses undergoing celiotomy for colic. SETTING: University teaching hospital. ANIMALS: Sixty-seven client-owned horses >1 year of age with POR were each matched to 2 controls with similar surgical lesions that did not demonstrate POR. MEASUREMENTS AND MAIN RESULTS: Survival was significantly lower in cases (65.7%) than controls (96.1%). Factors found to be associated with POR included decreased net fluid volume administered on day 1 postoperatively, increased age, and performing a resection and anastomosis. Mean time until onset of POR was 20.4 hours postoperatively. PCV was significantly higher immediately following surgery and at 24 hours postoperatively in horses that developed POR compared with matched controls. There was no association between electrolyte values at presentation or administration of potassium, calcium, or magnesium in the postoperative period and the subsequent development of reflux. CONCLUSIONS: In the perioperative period, IV fluid volume overload and electrolyte abnormalities were not contributing factors in the development of POR in this population of surgical colic patients. Close postoperative monitoring with consideration and correction of pre- and postoperative fluid deficits is recommended. PMID- 30302923 TI - Super-achromatic optical coherence tomography capsule for ultrahigh-resolution imaging of esophagus. AB - Endoscopic optical coherence tomography (OCT) is a noninvasive technology allowing for imaging of tissue microanatomies of luminal organs in real time. Conventional endoscopic OCT operates at 1300 nm wavelength region with a suboptimal axial resolution limited to 8-20 MUm. In this paper, we present the first ultrahigh-resolution tethered OCT capsule operating at 800 nm and offering about 3- to 4-fold improvement of axial resolution (plus enhanced imaging contrast). The capsule uses diffractive optics to manage chromatic aberration over a full ~200 nm spectral bandwidth centering around 830 nm, enabling to achieve super-achromaticity and an axial resolution of ~2.6 MUm in air. The performance of the OCT capsule is demonstrated by volumetric imaging of swine esophagus ex vivo and sheep esophagus in vivo, where fine anatomic structures including the sub-epithelial layers are clearly identified. The ultrahigh resolution and excellent imaging contrast at 800 nm of the tethered capsule suggest the potential of the technology as an enabling tool for surveillance of early esophageal diseases on awake patients without the need for sedation. PMID- 30302924 TI - Imaging phenotype of multiple mitochondrial dysfunction syndrome 2, a rare BOLA3 associated leukodystrophy. AB - Multiple mitochondrial dysfunction syndrome (MMDS) is a rare disorder of systemic energy metabolism associated with mutations in genes having a vital role in production of iron-sulfur clusters, important for the normal maturation of lipoate-containing 2-oxoacid dehydrogenases and for the assembly of the mitochondrial respiratory chain complexes. MMDS 2 associated with BOLA3 mutation presents in early infancy and is characterized by developmental regression, severe encephalopathy, optic atrophy, and cardiomyopathy. Neuroimaging phenotype associated with MMDS 2 has never been described in its entirety in literature, with few reported cases till date. None of the published cases mention findings demonstrated in our case, a proband with biallelic BOLA3 variants, such as necrotic/cavitary lesions within the centrum semiovale, restricted diffusivity within the white matter, areas of central enhancement within the centrum semiovale presumably related to leakage of contrast within the necrotic center, enhancement of bilateral optic nerves, and markedly elevated lactate on magnetic resonance spectroscopy. PMID- 30302922 TI - CTHRC1 overexpression predicts poor survival and enhances epithelial-mesenchymal transition in colorectal cancer. AB - Collagen triple helix repeat containing (CTHRC1), which was identified as a cancer-related factor, is a promigratory protein involved in multiple processes, including vascular remodeling, antifibrosis, metabolism, bone formation, and cancer. In this study, we aimed to investigate the clinical significance and possible role of CTHRC1 in the process of epithelial-mesenchymal transition (EMT) in colorectal cancer (CRC). Here, we revealed that CTHRC1 mRNA and protein levels are both upregulated in CRC tissues compared with those of paired noncancerous tissues. Moreover, the overexpression of CTHRC1 correlated with poor prognosis in patients with CRC (especially colon cancer). Furthermore, we showed that CTHRC1 induced EMT and promoted cell motility in CRC cells. Importantly, we demonstrated that CTHRC1 promoted EMT by activating transforming growth factor-beta (TGF-beta) signaling, revealing a possible effective therapeutic treatment for patients with CRC. PMID- 30302925 TI - Physical activity and exercise as a universal depression prevention in young people: A narrative review. AB - AIM: The aim of this narrative summary was to examine the efficacy of physical activity and exercise as a universal prevention for depression in young people. METHODS: We conducted a search of the literature in the open-access evidence database of controlled trials and systematic reviews in youth mental health, an initiative between Orygen, The National Centre of Excellence in Youth Mental Health and headspace, National Youth Mental Health Foundation. In April 2018, we searched for all papers published between 1980 and 2017 relating to "Depressive Disorder" under the "Universal Prevention" illness stage and classified as "Physical activity/Exercise" under the treatment/intervention classification. Systematic reviews, randomized control trials (RCTs) and controlled clinical trials were all included. RESULTS: A total of 11 papers were returned. Three of these studies were observational and eight studies were controlled trials. The reviewed studies indicate that exercise and physical activity might be an effective universal depression prevention intervention for young people. Three of the controlled studies had a passive control group or no control group and only one study had longer-term follow-up. No trial used a longitudinal design to determine if interventions prevent the onset of new cases of depression. CONCLUSIONS: The studies reviewed in the current review demonstrate a bidirectional relationship between physical activity, exercise and adolescent mental health. The results of the current review suggest that physical activity and exercise programs designed to increase the level of activity in young people should be implemented to be attractive and achievable to young people that may have poor psychological health.

AB - A high-throughput method (>= 106 of clones can be analysed on a single agar plate) for the selection of ester-hydrolysing enzymes was developed based on the uridine auxotrophy of Escherichia coli strain DH10B DeltapyrFEC and the acylated derivatives 2',3',5'-O-tri-acetyluridine and 2',3',5'-O-tri-hexanoyluridine as the sole source of uridine. The proposed approach permits the selection of hydrolases belonging to different families and active towards different substrates. Moreover, the ester group of the substrate used for the selection, at least partly, determined the specificity of the selected enzymes. PMID- 30302932 TI - Proceedings of the fifth international RASopathies symposium: When development and cancer intersect. AB - This report summarizes and highlights the fifth International RASopathies Symposium: When Development and Cancer Intersect, held in Orlando, Florida in July 2017. The RASopathies comprise a recognizable pattern of malformation syndromes that are caused by germ line mutations in genes that encode components of the RAS/mitogen-activated protein kinase (MAPK) pathway. Because of their common underlying pathogenetic etiology, there is significant overlap in their phenotypic features, which includes craniofacial dysmorphology, cardiac, cutaneous, musculoskeletal, gastrointestinal and ocular abnormalities, neurological and neurocognitive issues, and a predisposition to cancer. The RAS pathway is a well-known oncogenic pathway that is commonly found to be activated in somatic malignancies. As in somatic cancers, the RASopathies can be caused by various pathogenetic mechanisms that ultimately impact or alter the normal function and regulation of the MAPK pathway. As such, the RASopathies represent an excellent model of study to explore the intersection of the effects of dysregulation and its consequence in both development and oncogenesis. PMID- 30302934 TI - Dynamic visualization of the recovery of mouse hepatobiliary metabolism to acetaminophen-overdose damage. AB - Acetaminophen (APAP) overdose is one of the world's leading causes of drug induced hepatotoxicity. Although traditional methods such as histological imaging and biochemical assays have been successfully applied to evaluate the extent of APAP-induced liver damage, detailed effect of how APAP overdose affect the recovery of hepatobiliary metabolism remains unclear.is not completely understood. In this work, we used intravital multiphoton microscopy to image and quantify hepatobiliary metabolism of the probe 6-carboxyfluorescein diacetate (6 CFDA) in APAP-overdose mice. We analyzed hepatobiliary metabolism for up to 7 days following the overdose and found that the excretion of the probe molecule was the most rapid one day following APAP overdose and slowed down on Days 2 and 3. On Day 7, probe excretion capability has exceeded that of the normal mice, suggesting that newly regenerated hepatocytes have higher metabolic capabilities. Our approach may be further developed applied to studying drug-induced hepatotoxicity in vivo. This article is protected by copyright. All rights reserved. PMID- 30302935 TI - Retrospective evaluation of 4 methods for outcome prediction in overt disseminated intravascular coagulation in dogs (2009-2014): 804 cases. AB - OBJECTIVE: The clinical diagnosis of disseminated intravascular coagulation (DIC) in dogs is challenging. It was hypothesized that dogs with laboratory abnormalities consistent with overt DIC have increased mortality and hence survival could be used to evaluate the performance of DIC scoring systems. Four DIC scoring systems were compared in clinically ill dogs: The International Society of Thrombosis and Haemostasis (ISTH) score; a previously published veterinary DIC score; a system using in-house reference intervals (RIs) for coagulation assays; and the published veterinary DIC score modified by use of in house RI values. DESIGN: Retrospective cohort study. SETTING: University teaching hospital. ANIMALS: Eight hundred four client-owned dogs with underlying disorders associated with DIC. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Medical records were reviewed to identify dogs for which a coagulation panel consisting of coagulation times, D-dimer concentration, antithrombin activity, fibrinogen concentration, and platelet count had been analyzed. Four methods for overt DIC scoring were then applied, and the ability of these scores to predict mortality was evaluated. Use of institution RIs for diagnosis of overt DIC provided the most accurate prognostic assessment. A score based on abnormalities in 3 of 6 parameters to identify overt DIC was 72.7% sensitive and 80.9% specific for mortality and was accurate in 78.4% of cases. The mortality rate of dogs diagnosed with overt DIC via this method was 62.5%, compared to 12.9% in the dogs not in overt DIC, a relative risk of nonsurvival of 4.84 (95% confidence interval 3.80-6.16). CONCLUSIONS: In dogs at-risk for DIC, an in-house RI scoring system accurately predicted mortality. With further prospective validation, this system holds promise as a diagnostic tool for consistent characterization of overt DIC in clinical studies and clinical practice. PMID- 30302936 TI - Efficacy and safety of azilsartan medoxomil/chlortalidone fixed-dose combination in hypertensive patients uncontrolled on azilsartan medoxomil alone: A randomized trial. AB - Patients with grade 2-3 essential hypertension and postplacebo mean clinic systolic blood pressure (SBP) 160-190 mm Hg and 24-hour SBP 140-175 mm Hg by ambulatory blood pressure monitoring (ABPM) received 40 mg azilsartan medoxomil (AZL-M) monotherapy for 4 weeks. "Nonresponders" were then randomized to 8 weeks of double-blind treatment with AZL-M 40 mg, AZL-M/chlortalidone (CLD) 40/25, or AZL-M/CLD 40/12.5 mg. After 8 weeks, mean clinic SBP change was -21.1 (+/-1.04) mm Hg for AZL-M/CLD 40/25 mg, -15.8 (+/-1.08) mm Hg for AZL-M/CLD 40/12.5 mg, and -6.4 (+/-1.05) mm Hg for AZL-M 40 mg (P < 0.001 for both AZL-M/CLD vs AZL-M, ANCOVA). Drug discontinuation rates were 8.9% (AZL-M/CLD 40/25 mg), 7.5% (AZL-M 40 mg), and 3.9% (AZL-M/CLD 40/12.5 mg). Creatinine increased in 8.1% (AZL-M/CLD 40/25), 3.1% (AZL-M/CLD 40/12.5 mg), and 3.0% (AZL-M 40 mg) of patients. AZL M/CLD was effective and well tolerated in patients not achieving blood pressure targets with AZL-M. PMID- 30302937 TI - Concise Reviews: Stem Cells and Kidney Regeneration: An Update. AB - Significant progress has been made to advance stem cell products as potential therapies for kidney diseases: various kinds of stem cells can restore renal function in preclinical models of acute and chronic kidney injury. Nonetheless this literature contains contradictory results, and for this reason, we focus this review on reasons for apparent discrepancies in the literature, because they contribute to difficulty in translating renal regenerative therapies. Differences in methodologies used to derive and culture stem cells, even those from the same source, in addition to the lack of standardized renal disease animal models (both acute and chronic), are important considerations underlying contradictory results in the literature. We propose that harmonized rigorous protocols for characterization, handling, and delivery of stem cells in vivo could significantly advance the field, and present details of some suggested approaches to foster translation in the field of renal regeneration. Our goal is to encourage coordination of methodologies (standardization) and long-lasting collaborations to improve protocols and models to lead to reproducible, interpretable, high-quality preclinical data. This approach will certainly increase our chance to 1 day offer stem cell therapeutic options for patients with all-too-common renal diseases. PMID- 30302938 TI - Concise Review: The Current State of Human in vitro Cardiac Disease Modeling: A Focus on Gene Editing and Tissue Engineering. AB - Until recently, in vivo and ex vivo experiments were the only means to determine factors and pathways involved in disease pathophysiology. After the generation of characterized human embryonic stem cell lines, human diseases could readily be studied in an extensively controllable setting. The introduction of human-induced pluripotent stem cells, a decade ago, allowed the investigation of hereditary diseases in vitro. In the field of cardiology, diseases linked to known genes have successfully been studied, revealing novel disease mechanisms. The direct effects of various mutations leading to hypertrophic cardiomyopathy, dilated cardiomyopathy, arrythmogenic cardiomyopathy, or left ventricular noncompaction cardiomyopathy are discovered as a result of in vitro disease modeling. Researchers are currently applying more advanced techniques to unravel more complex phenotypes, resulting in state-of-the-art models that better mimic in vivo physiology. The continued improvement of tissue engineering techniques and new insights into epigenetics resulted in more reliable and feasible platforms for disease modeling and the development of novel therapeutic strategies. The introduction of CRISPR-Cas9 gene editing granted the ability to model diseases in vitro independent of induced pluripotent stem cells. In addition to highlighting recent developments in the field of human in vitro cardiomyopathy modeling, this review also aims to emphasize limitations that remain to be addressed; including residual somatic epigenetic signatures induced pluripotent stem cells, and modeling diseases with unknown genetic causes. Stem Cells Translational Medicine 2018. PMID- 30302939 TI - Different Effects of Pro-Inflammatory Factors and Hyperosmotic Stress on Corneal Epithelial Stem/Progenitor Cells and Wound Healing in Mice. AB - Chronic inflammation and severe dry eye are two important adverse factors for the successful transplant of cultured limbal stem cells. The aim of this study was to investigate the effects of inflammation and hyperosmotic stress (a key pathological factor in dry eye) on corneal epithelial stem cells (CESCs) and corneal epithelial wound healing. We observed that the CESCs exhibited significant morphological changes when treated with interleukin-1 beta (IL 1beta), tumor necrosis factor alpha (TNF-alpha), or hyperosmotic stress. Colony forming efficiency or colony-forming size was decreased with the increasing concentrations of IL-1beta, TNF-alpha, or hyperosmotic stress, which was exacerbated when treated simultaneously with pro-inflammatory factors and hyperosmotic stress. However, the colony-forming capacity of CESCs recovered more easily from pro-inflammatory factor treatment than from hyperosmotic stress treatment. Moreover, when compared with pro-inflammatory factors treatment, hyperosmotic stress treatment caused a more significant increase of apoptotic and necrotic cell numbers and cell cycle arrest in the G2/M phase. Furthermore, the normal ability of corneal epithelial wound healing in the mice model was suppressed by both pro-inflammatory factors and hyperosmotic stress treatment, and especially severely by hyperosmotic stress treatment. In addition, inflammation combined with hyperosmotic stress treatment induced more serious epithelial repair delays and apoptosis in corneal epithelium. Elevated levels of inflammatory factors were found in hyperosmotic stress-treated cells and mice corneas, which persisted even during the recovery period. The results suggested that pro-inflammatory factors cause transient inhibition, while hyperosmotic stress causes severe apoptosis and necrosis, persistent cell cycle arrest of CESCs, and severe corneal wound healing delay.

PMID- 30302940 TI - Pre-hospital administration of ticagrelor in diabetic patients with ST-elevation myocardial infarction undergoing primary angioplasty: A sub-analysis of the ATLANTIC trial. AB - OBJECTIVE: We investigated, in the contemporary era of ST-elevation myocardial infarction (STEMI) treatment, the influence of diabetes mellitus (DM) on cardiovascular outcomes, and whether pre-hospital administration of ticagrelor may affect these outcomes in a subgroup of STEMI patients with DM. BACKGROUND: DM patients have high platelet reactivity and a prothrombotic condition which highlight the importance of an effective antithrombotic regimen in this high-risk population. METHODS: In toal 1,630 STEMI patients enrolled in the ATLANTIC trial who underwent primary percutaneous coronary intervention (PCI) were included. Multivariate analysis was used to explore the association of DM with outcomes and potential treatment-by-diabetes interaction was tested. RESULTS: A total of 214/1,630 (13.1%) patients had DM. DM was an independent predictor of poor myocardial reperfusion as reflected by less frequent ST-segment elevation resolution (>=70%) after PCI (OR 0.59, 95% CI 0.43-0.82, P < 0.01) and was an independent predictor of the composite 30-day outcomes of death/new myocardial infarction (MI)/urgent revascularization/definite stent thrombosis (ST) (OR 2.80, 95% CI 1.62-4.85, P < 0.01), new MI or definite acute ST (OR 2.46, 95% CI 1.08 5.61, P = 0.03), and definite ST (OR 10.00, 95% CI 3.54-28.22, P < 0.01). No significant interaction between pre-hospital ticagrelor vs in-hospital ticagrelor administration and DM was present for the clinical, electrocardiographic and angiographic outcomes as well as for thrombolysis in myocardial infarction major bleeding. CONCLUSIONS: DM remains independently associated with poor myocardial reperfusion and worse 30-day clinical outcomes. No significant interaction was found between pre-hospital vs in-hospital ticagrelor administration and DM status. Further approaches for the treatment of DM patients are needed.

PMID- 30302941 TI - Energy Transfer-Assisted Whispering Gallery Mode Lasing in Conjugated Polymer/Europium Hybrid Microsphere Resonators. AB - Lanthanide metal complexes display luminescence with narrow bandwidth. Here, we present coupling of the luminescence from europium ion (Eu3+ ) with whispering gallery modes (WGMs) in conjugated polymer microsphere resonators. Self-assembly of fluorene-terpyridine alternating copolymer, coordinated by Eu3+ (F8tpy-Eu3+ ), forms well-defined microspheres with an average diameter of 3.2 MUm. Upon focused laser excitation, a microsphere of F8tpy copolymer displays WGM photoluminescence (PL) at a wide spectral range from 420 to 680 nm. In contrast, F8tpy-Eu3+ hybrid microspheres exhibit sharp WGM PL at a narrow spectral range of 615-630 nm, which is characteristic of luminescence from Eu3+ . The PL behavior indicates that photoinduced energy transfer from F8tpy to Eu3+ occurs efficiently. Furthermore, the intensity of the PL peak increases nonlinearly upon strong pumping, indicating that a lasing action appears with the threshold of 1.85 mJ cm-2 . These results will pave the way for developing microlasers and photonic devices from soft organic materials. PMID- 30302942 TI - Arabidopsis BIG1 and BIG5 are crucial for male gametophyte transmission. AB - Arabidopsis contains five Brefeldin A-inhibited guanine nucleotide exchange factors (BIGs), which play a critical role in vesicle biogenesis for protein traffic from the Golgi to the plasma membrane. Biological processes regulated by BIG1-BIG4 are postulated to be distinct from those by BIG5. However, we show that the self-pollinated BIG1+/- big5 silique do not produce homozygous seeds, and some pollen tubes from BIG1+/- big5 anthers grew slowly in vitro and failed to target nearby ovules in vivo. We identified the big1 big5 homozygote from the progeny of BIG1+/- big5 plants transformed with BIG5, whose expression is driven by a pollen-specific promoter pLat52, indicating that male gametophyte transmission is blocked in the double mutant. Confocal microscopy indicated that BIG1 and BIG5 are co-localized in the Golgi network. Thus, our data indicate that BIG1 and BIG5 are crucial for male gametophyte transmission. PMID- 30302943 TI - Classification of Established Atopic Dermatitis in Children with the In Vivo Imaging Methods. AB - Atopic dermatitis (AD) is a cutaneous disease resulting from a defective barrier and dysregulated immune response. The severity scoring of atopic dermatitis (SCORAD) is used to classify AD. Noninvasive imaging approaches supplementary to SCORAD were investigated. Cr:forsterite laser-based microscopy was employed to analyze endogenous third-harmonic generation (THG) and second-harmonic generation (SHG) signals from skin. Imaging parameters were compared between different AD severities. 3D reconstruction of imaged skin layers were performed. Finally, statistic models from quantitative imaging parameters were developed for predicting disease severity. Our data demonstrate that THG signal intensity of lesional skin in AD were significantly increased and was positively correlated with AD severity. Characteristic GLCM values were observed in more severe AD. In the 3D reconstruction video, individual dermal papilla and obvious fibrosis in the upper papillary dermis were easily identified. Our estimation models could predict the disease severity of AD patients with an accuracy of nearly 85%. The THG signal intensity and characteristic GLCM patterns are associated with AD severity and can serve as quantitative predictive parameters. Our imaging approach can be used to identify the histopathological changes of AD objectively, and to complement the SCORAD index, thus improving the accuracy of classifying AD severity.

AB - Women may not have an accurate perception of their own body weight and vary in understanding about healthy weight. The study's aim was to assess women's accuracy of their own body mass index (BMI), understanding of the healthiest body weight and opinion of the most attractive body figure. We surveyed 385 women (age, 19-77 years) attending our obstetrics and gynaecology clinics with an anonymous survey demonstrating a selection of Body Image Scale graphics to represent their current body, the healthiest body and the most attractive body. There was a significant positive correlation between Body Image Scale graphic selected and BMI (r = 0.80; P < 0.0001). The selected Body Image Scale graphic was accurate or within 1 graphic higher or lower than BMI in 88% of participants. The mean BMI of women accurately selecting the appropriate graphic (BMI, 29 +/- 8 kg m-2 ) was significantly lower than that of women selecting the graphic lower than their BMI (BMI, 37 +/- 7 kg m-2 ) but was significantly higher than those selecting a graphic higher than their BMI (BMI, 25 +/- 4 kg m-2 ). For healthiest figure, 58% women selected a graphic representing overweight BMI and 2% women selected a graphic with Class 1 obesity. For most attractive figure, 48% women selected a graphic representing normal BMI, 49% women selected a graphic representing overweight BMI and 1% of women selected a graphic with Class 1 obesity. It is important to provide counselling about ideal weight, healthy lifestyle choices and consequences of obesity. PMID- 30302947 TI - Social jetlag, sleep-related parameters, and glycemic control in adults with type 1 diabetes: Results of a cross-sectional study. AB - BACKGROUND: Social jetlag (SJL) is a small recurrent circadian rhythm disruption and the most frequent form of circadian rhythm misalignment. The main aim of this study was to investigate the effect of SJL on glycemic control, as assessed by HbA1c, in real-life settings. METHODS: In all, 115 consecutive patients with type 1 diabetes (T1D) were analyzed cross-sectionally. Data on bedtime, sleep onset latency, and wake up time on weekdays and weekends during the previous month were collected from all participants and used to calculate SJL, chronotype, and sleep duration. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). A PSQI score > 5 was considered as an indicator of poor sleep quality. RESULTS: Patients with SJL >= 1 hour had significantly higher adjusted values of HbA1c than those with SJL <1 hour (8.7% vs 8.0%; P = 0.029). In unadjusted multivariate regression analysis, SJL >= 1 hour and poor sleep quality were significant predictors of HbA1c values, explaining 22.7% and 23.5%, respectively, of the increase in HbA1c. After adjusting for age, sex, diabetes duration, insulin dose (kg/d), insulin regimen and body mass index, only SJL >= 1 hour remained associated with HbA1c (beta = 0.253; P = 0.026). There was no significant interaction between SJL >= 1 hour and poor sleep quality in either the unadjusted or adjusted models (Pinteraction = 0.914). CONCLUSIONS: In patients with T1D, SJL is associated with poor glycemic control, acting independently of sleep quality, sleep duration, and chronotype to exert a deleterious effect on glycemic control. PMID- 30302946 TI - The role of tissue and serum carcinoembryonic antigen in stages I to III of colorectal cancer-A retrospective cohort study. AB - PURPOSE: Tissue carcinoembryonic antigen (t-CEA) and serum carcinoembryonic antigen (s-CEA) expression profiles are the most useful tumor markers for the diagnosis and evaluation of colorectal cancer (CRC) worldwide; however, their roles in CRC progression remain controversial. This study aimed to compare the prognostic values of both s-CEA and t-CEA in CRC. METHODS: A total of 517 patients from January 2006 to December 2010 with stages I-III CRC were retrospectively examined, with 5-year postoperative follow-up and death as end points. T-CEA expression, s-CEA expression, and clinical pathological parameters were inputted into the SPSS 21.0 software. The Kaplan-Meier method was used to analyze the 5-year disease-free survival (DFS) rate of patients in different tumor node metastasis (TNM) stages based on t-CEA and s-CEA expression. RESULTS: Tumor differentiation and the number of positive lymph node harvests were significantly different among the t-CEA groups (P < 0.001, P = 0.002); however, clinicopathological features showed no significant difference. The groups with high s-CEA and t-CEA expression had a significantly poorer prognosis than those with low s-CEA (P = 0.021) and t-CEA (P < 0.01) expression, respectively. The multivariate analysis demonstrated that t-CEA was an independent prognostic factor in CRC (P < 0.001), but s-CEA was not (P = 0.339). The 5-year disease-free survival rates among the t-CEA groups were significantly different in stages I, II, and III of CRC (P = 0.001, P < 0.001, P < 0.001), whereas in the s-CEA groups, this difference was observed only in stage III (P = 0.014). CONCLUSION: This study shows that postoperative t-CEA expression is an independent factor associated with poorer CRC prognosis and has a higher prognostic value than that of preoperative s-CEA expression. PMID- 30302948 TI - Genetic inactivation of ZCCHC6 suppresses IL-6 expression and reduces the severity of experimental osteoarthritis in mice. AB - OBJECTIVE: Cytokine expression is tightly regulated post-transcriptionally but high levels of IL-6 in osteoarthritis (OA) indicate disruption of regulatory mechanisms. ZCCHC6 enzyme is implicated in post-transcriptional regulation of inflammatory cytokine expression but its role in OA pathogenesis is unknown. Here we studied whether ZCCHC6 directs the expression of IL-6 and influence OA pathogenesis in vivo. METHODS: Human and mouse chondrocytes were stimulated with recombinant IL-1beta. We knocked down the expression of ZCCHC6 in human chondrocytes by siRNAs. IL-6 transcript stability was determined by Actinomycin-D chase and 3'-uridylation of miRNAs was determined by deep sequencing. Zcchc6-/- mice were produced by gene targeting. OA was surgically induced in the knee joints of mice and the disease severity was scored using a semi-quantitative scoring system. RESULTS: ZCCHC6 was markedly upregulated in the damaged cartilage from human OA patients and from wild type mice with surgically-induced OA. Overexpression of ZCCHC6 induced the expression of IL-6 and its knockdown reduced the IL-6 transcript stability and IL-1beta-induced expression in chondrocytes. Reintroduction of Zcchc6 in Zcchc6-/- chondrocytes rescued the IL-1beta-induced IL-6 expression. Knockdown of ZCCHC6 reduced the population of miR-26b with 3' uridylation by 60%. Zcchc6-/- mice with surgically-induced OA produced low levels of IL-6 and showed reduced cartilage damage and synovitis in the joints. CONCLUSIONS: ZCCHC6 enhance IL-6 expression in chondrocytes through transcript stabilization and by uridylating miR-26b which abrogates repression of IL-6. Inhibition of IL-6 expression and significantly reduced OA severity in Zcchc6-/- mice identify ZCCHC6 as a novel therapeutic target to inhibit disease pathogenesis.

PMID- 30302949 TI - Improvement of radiographer commenting accuracy of the appendicular skeleton following a short course in plain radiography image interpretation: A pilot study. AB - INTRODUCTION: Radiographers are at times required to provide preliminary information on plain radiography when significant findings are identified. The aim of the study was to evaluate the effectiveness of two short training modules to improve the accuracy of image interpretation of the appendicular skeleton amongst a group of radiographers. METHODS: Eight radiographers volunteered to participate in the study. All undertook a pre-test and, following delivery of course materials, an immediate post-test for two consecutive modules. A retention test was undertaken 6 months later. Sensitivity (Sn), specificity (Sp) and accuracy (Acc) scores were evaluated against the "Gold Standard" radiologists' reports. Paired-samples t-tests were carried out to compare image interpretation scores between the start of module one to the end of module two, and between the end of module 2 and 6 months later. Summary receiver operating characteristics (SROC) scores on each of the participants' module two post-test study results were undertaken. RESULTS: Significant improvements in scores were achieved between the mean (SD) scores of module 1 pre-test (77.5 (+/-3.9)) and the module 2 post-test (83.6 (+/-3.2) (P =0.022)). Sn, Sp and Acc scores increased from the start of module 1 pre-test to the end of module 2 post-test (Sn: 82.28-86.25%; Sp: 75.29-84.66%; Acc: 81.68-85.97%). The retention test revealed a non significant reduction in mean scores (80.0 (+/-5.1)) when compared to post-test module 2 (83.6 (+/-3.2) (P =0.184)). SROC revealed an area under the curve of 0.90. CONCLUSION: Participants achieved significant improvements in commenting accuracy on plain radiography of the appendicular skeleton after completion of the two modules. However, continuous application and ongoing professional development is essential in order to maintain and develop the skills acquired. PMID- 30302950 TI - Supramolecular Nanofibers of Drug-Peptide Amphiphile and Affibody Suppress HER2+ Tumor Growth. AB - Antibody-based medicines and nanomedicines are very promising for cancer therapy due to the high specificity and efficacy of antibodies. However, antibody-drug conjugates and antibody-modified nanomaterials frequently suffer from low drug loading and loss of functions due to the covalent modification of the antibody. A novel and versatile strategy to prepare supramolecular nanomaterials by the coassembly of an affibody (antiHER2) and drug-peptide amphiphiles is reported here. During the enzyme-instructed self-assembly process, the drug-peptide amphiphile can coassemble with the affibody, resulting in supramolecular nanofibers in hydrogels. The drug loading in the supramolecular nanofibers is high (>30 wt%), and the stability of antiHER2 is significantly improved in the nanofibers at 37 degrees C (>15 d in vitro). The supramolecular nanofibers exhibit high affinity for HER2+ cancer cells and can be efficiently taken up by these cells. In a mouse tumor model, the supramolecular nanofibers abolish HER2+ NCI-N87 tumor growth due to the good accumulation and retention of nanofibers in tumor. This study provides a novel strategy to prepare nanomedicines with high drug loading and high specificity. PMID- 30302951 TI - Dilemma of Asthma Treatment in Mild Patients. AB - Inhaled corticosteroids (ICSs) have been widely used as a key medication for asthma control. However, ICSs have been known to cause respiratory infections, such as pneumonia and pulmonary tuberculosis. Consequently, a dilemma exists regarding recommendation of persistent lifetime use of ICSs to mild asthma patients. Short-acting beta-agonists (SABAs) have also been widely used for symptom relief. However, SABAs have been reported to increase the risk of asthma related death, though incidences have been very rare. Consequently, a dilemma exists regarding recommendation of a SABA alone without an ICS or a controller to asthma patients even with very mild disease. In the real world, asthma patients tend to intermittently use ICS and more likely to be dependent on SABA since many patients want immediate relief of their symptoms. Consequently, a dilemma exists regarding the underuse of ICSs but the overuse of SABAs. One strategy for solving the presented dilemma would be identification of patients with asthma who require persistent use of asthma controllers. Such patients, who may be referred to as "persistent controller users," should continuously receive ICSs, even under controlled states of asthma. Another strategy would be a patient-adjusted, symptom-driven, intermittent-to-regular treatment combining low-dose ICS/rapid onset long-acting beta-agonists instead of using a SABA alone or with low-dose ICS for the asthma patients with mild disease. Both of these two strategies could avoid the risky treatment of a SABA alone without an ICS and could reduce the dose of ICS with the maintenance of asthma control. PMID- 30302952 TI - The Development of the Korean Lung Cancer Registry (KALC-R). AB - Lung cancer is the most commonly diagnosed cancer and the leading cause of cancer related deaths worldwide. Globally, there were an estimated 1.8 million new cases and 1.59 million deaths in 2012. In Korea, the incidence of lung cancer is increasing and 24,267 (47.6/100,000) patients with lung cancer were registered at the Korea Central Cancer Registry in 2015. Previous nationwide surveys of lung cancer were performed in 1998 by the Korean Academy of Tuberculosis and Respiratory Diseases and in 2007 by the Korean Association for Lung Cancer (KALC), but the studies faced difficulties in maintaining lung cancer registry because of limitations regarding the Private Information Protection Act. To produce unbiased and reliable epidemiological data, the KALC and Korean Central Cancer Registry developed a detailed lung cancer registry (KALC-R) data structure. Following a pilot survey of 489 lung cancer cases in 2013, about 10% of the sampled lung cancer cases from the Korean Central Cancer Registry are surveyed each year. With the analysis of detailed data from the KALC-R, an important epidemiological background for scientific research or policy development is expected to be generated. PMID- 30302953 TI - Infection Source and Epidemiology of Nontuberculous Mycobacterial Lung Disease. AB - Nontuberculous mycobacteria (NTM) are ubiquitous organisms that are generally found not only in the natural environment but also in the human engineered environment, including water, soil, and dust. These organisms can form biofilms and can be readily aerosolized because they are hydrophobic owing to the presence of the lipid-rich outer membrane. Aerosolization and subsequent inhalation were the major route of NTM lung disease. Water distribution systems and household plumbing are ideal habit for NTM and the main transmission route from natural water to household. NTM have been isolated from drinking water, faucets, pipelines, and water tanks. Studies that used genotyping have shown that NTM isolates from patients are identical to those in the environment, that is, from shower water, showerheads, tap water, and gardening soil. Humans are likely to be exposed to NTM in their homes through simple and daily activities, such as drinking, showering, or gardening. In addition to environmental factors, host factors play an important role in the development of NTM lung disease. The incidence and prevalence of NTM lung disease are increasing worldwide, and this disease is rapidly becoming a major public health problem. NTM lung disease is associated with substantially impaired quality of life, increased morbidity and mortality, and high medical costs. A more comprehensive understanding of the infection source and epidemiology of NTM is essential for the development of new strategies that can prevent and control NTM infection. PMID- 30302954 TI - Sepsis: Early Recognition and Optimized Treatment. AB - Sepsis is a life-threatening condition caused by infection and represents a substantial global health burden. Recent epidemiological studies showed that sepsis mortality rates have decreased, but that the incidence has continued to increase. Although a mortality benefit from early-goal directed therapy (EGDT) in patients with severe sepsis or septic shock was reported in 2001, three subsequent multicenter randomized studies showed no benefits of EGDT versus usual care. Nonetheless, the early administration of antibiotics and intravenous fluids is considered crucial for the treatment of sepsis. In 2016, new sepsis definitions (Sepsis-3) were issued, in which organ failure was emphasized and use of the terms "systemic inflammatory response syndrome" and "severe sepsis" was discouraged. However, early detection of sepsis with timely, appropriate interventions increases the likelihood of survival for patients with sepsis. Also, performance improvement programs have been associated with a significant increase in compliance with the sepsis bundles and a reduction in mortality. To improve sepsis management and reduce its burden, in 2017, the World Health Assembly and World Health Organization adopted a resolution that urged governments and healthcare workers to implement appropriate measures to address sepsis. Sepsis should be considered a medical emergency, and increasing the level of awareness of sepsis is essential. PMID- 30302955 TI - Potential Therapeutic Strategy in Chronic Obstructive Pulmonary Disease Using Pioglitazone-Augmented Wharton's Jelly-Derived Mesenchymal Stem Cells. AB - BACKGROUND: A recent study reported that mesenchymal stem cells possess potential cellular therapeutic properties for treating patients with chronic obstructive pulmonary disease, which is characterized by emphysema. We examined the potential therapeutic effect of Wharton's Jelly-derived mesenchymal stem cells (WJMSCs), following pretreatment with pioglitazone, in lung regeneration mouse emphysema models. METHODS: We used two mouse emphysema models, an elastase-induced model and a cigarette smoke-induced model. We intravenously injected WJMSCs (1*104/mouse) to mice, pretreated or not, with pioglitazone for 7 days. We measured the emphysema severity by mean linear intercepts (MLI) analysis using lung histology. RESULTS: Pioglitazone pretreated WJMSCs (pioWJMSCs) were associated with greater lung regeneration than non-augmented WJMSCs in the two mouse emphysema models. In the elastase-induced emphysema model, the MLIs were 59.02+/-2.42 MUm (n=6), 72.80+/-2.87 MUm (n=6), for pioWJMSCs injected mice, and non-augmented WJMSCs injected mice, respectively (p<0.01). Both pioWJMSCs and non augmented WJMSCs showed regenerative effects in the cigarette smoke emphysema model (MLIs were 41.25+/-0.98 [n=6] for WJMSCs and38.97+/-0.61 MUm [n=6] for pioWJMSCs) compared to smoking control mice (51.65+/-1.36 MUm, n=6). The mean improvement of MLI appeared numerically better in pioWJMSCs than in non-augmented WJMSCs injected mice, but the difference did not reach the level of statistical significance (p=0.071). CONCLUSION: PioWJMSCs may produce greater lung regeneration, compared to non-augmented WJMSCs, in a mouse emphysema model. PMID- 30302956 TI - Correlation between GenoType MTBDRplus Assay and Phenotypic Susceptibility Test for Prothionamide in Patients with Genotypic Isoniazid Resistance. AB - BACKGROUND: The purpose of this study was to analyze the relationship between the gene mutation patterns by the GenoType MTBDRplus (MTBDRplus) assay and the phenotypic drug susceptibility test (pDST) results of isoniazid (INH) and prothionamide (Pto). METHODS: A total of 206 patients whose MTBDRplus assay results revealed katG or inhA mutations were enrolled in the study. The pDST results were compared to mutation patterns on the MTBDRplus assay. RESULTS: The katG and inhA mutations were identified in 68.0% and 35.0% of patients, respectively. Among the 134 isolated katG mutations, three (2.2%), 127 (94.8%) and 11 (8.2%) were phenotypically resistant to low-level INH, high-level INH, and Pto, respectively. Among the 66 isolated inhA mutations, 34 (51.5%), 18 (27.3%) and 21 (31.8%) were phenotypically resistant to low-level INH, high-level INH, and Pto, respectively. Of the 34 phenotypic Pto resistant isolates, 21 (61.8%), 11 (32.4%), and two (5.9%) had inhA, katG, and both gene mutations. CONCLUSION: It is noted that Pto may still be selected as one of the appropriate multidrug resistant tuberculosis regimen, although inhA mutation is detected by the MTBDRplus assay until pDST confirms a Pto resistance. The reporting of detailed mutation patterns of the MTBDRplus assay may be important for clinical practice, rather than simply presenting resistance or susceptibility test results. PMID- 30302957 TI - Pre-immigration Screening for Tuberculosis in South Korea: A Comparison of Smear- and Culture-Based Protocols. AB - BACKGROUND: Tuberculosis (TB) is the most important disease screened for upon patient history review during preimmigration medical examinations as performed in South Korea in prospective immigrants to certain Western countries. In 2007, the U.S. Centers for Disease Control and Prevention (CDC) changed the TB screening protocol from a smear-based test to the complete Culture and Directly Observed Therapy Tuberculosis Technical Instructions (CDOT TB TI) for reducing the incidence of TB in foreign-born immigrants. METHODS: This study evaluated the effect of the revised (as compared with the old) protocol in South Korea. RESULTS: Of the 40,558 visa applicants, 365 exhibited chest radiographic results suggestive of active or inactive TB, and 351 underwent sputum tests (acid-fast bacilli smear and Mycobacterium tuberculosis culture). To this end, using the CDOT TB TI, 36 subjects (88.8 per 105 of the population) were found to have TB, compared with only seven using the older U.S. CDC technical instruction (TI) (p<0.001). In addition, there were six drug-resistant cases which were identified (16.7 per 105 of the population), two of whom had multidrug-resistance (5.6 per 105 of the population). CONCLUSION: The culture-based 2007 TI identified a great deal of TB cases current to the individuals tested, as compared to older U.S. CDC TI. PMID- 30302958 TI - Direct and Indirect Costs of Chronic Obstructive Pulmonary Disease in Korea. AB - BACKGROUND: Understanding the burden of disease is important to establish cost effective treatment strategies and to allocate healthcare resources appropriately. However, little reliable information is available regarding the overall economic burden imposed by chronic obstructive pulmonary disease (COPD) in Korea. METHODS: This study is a multicenter observational research on the COPD burden in Korea. Total COPD costs were comprised of three categories: direct medical, direct non-medical, and indirect costs. For direct medical costs, institutional investigation was performed at 13 medical facilities mainly based on the claims data. For direct non-medical and indirect costs, site-based surveys were administered to the COPD patients during routine visits. Total costs were estimated using the COPD population defined in the recent report. RESULTS: The estimated total costs were approximately 1,245 million US dollar (1,408 billion Korean won). Direct medical costs comprised approximately 20% of the total estimated costs. Of these, formal medical costs held more than 80%. As direct non medical costs, nursing costs made up the largest percentage (39%) of the total estimated costs. Costs for COPD-related loss of productivity formed four fifths of indirect costs, and accounted for up to 33% of the total costs. CONCLUSION: This study shows for the first time the direct and indirect costs of COPD in Korea. The total costs were enormous, and the costs of nursing and lost productivity comprised approximately 70% of total costs. The results provide insight for an effective allocation of healthcare resources and to inform establishment of strategies to reduce national burden of COPD. PMID- 30302959 TI - Identification of Serial DNA Methylation Changes in the Blood Samples of Patients with Lung Cancer. AB - BACKGROUND: The development of lung cancer results from the interaction between genetic mutations and dynamic epigenetic alterations, although the exact mechanisms are not completely understood. Changes in DNA methylation may be a promising biomarker for early detection and prognosis of lung cancer. We evaluated the serial changes in genome-wide DNA methylation patterns in blood samples of lung cancer patients. METHODS: Blood samples were obtained for three consecutive years from three patients (2 years before, 1 year before, and after lung cancer detection) and from three control subjects (without lung cancer). We used the MethylationEPIC BeadChip method, which covers the 850,000 bp cytosine phosphate-guanine (CpG) site, to conduct an epigenome-wide analysis. Significant differentially methylated regions (DMRs) were identified using p-values <0.05 in a correlation test identifying serial methylation changes and serial increase or decrease in beta value above 0.1 for three consecutive years. RESULTS: We found three significant CpG sites with differentially methylated beta values and 7,105 CpG sites with significant correlation from control patients without lung cancer. However, there were no significant DMRs. In contrast, we found 11 significant CpG sites with differentially methylated beta values and 10,562 CpG sites with significant correlation from patients with lung cancer. There were two significant DMRs: cg21126229 (RNF212) and cg27098574 (BCAR1). CONCLUSION: This study revealed DNA methylation changes that might be implicated in lung cancer development. The DNA methylation changes may be the possible candidate target regions for the early detection and prevention of lung cancer. PMID- 30302960 TI - High Proportion of Adult Cases and Prevalence of Metabolic Syndrome in Type 1 Diabetes Mellitus Population in Korea: A Nationwide Study. AB - BACKGROUND: The prevalence and incidence of type 1 diabetes mellitus (T1DM) in all age groups and the prevalence of metabolic syndrome in patients with T1DM in Korea were estimated. METHODS: The incidence and prevalence of T1DM between 2007 and 2013 were calculated using the Korean National Health Insurance Service (NHIS) datasets of claims. Clinical characteristics and prevalence of metabolic syndrome in individuals with T1DM between 2009 and 2013 were determined using the database of NHIS preventive health checkups. RESULTS: The prevalence of T1DM in Korea between 2007 and 2013 was 0.041% to 0.047%. The annual incidence rate of T1DM in Korea in 2007 to 2013 was 2.73 to 5.02/100,000 people. Although the incidence rate of typical T1DM was highest in teenagers, it remained steady in adults over 30 years of age. In contrast, the incidence rate of atypical T1DM in 2013 was higher in people aged 40 years or older than in younger age groups. Age- and sex-adjusted prevalence of metabolic syndrome in patients with T1DM was 51.65% to 55.06% between 2009 and 2013. CONCLUSION: T1DM may be more common in Korean adults than previously believed. Metabolic syndrome may be a frequent finding in individuals with T1DM in Korea. PMID- 30302961 TI - Association of Thigh Muscle Mass with Insulin Resistance and Incident Type 2 Diabetes Mellitus in Japanese Americans. AB - BACKGROUND: Skeletal muscle plays a major role in glucose metabolism. We investigated the association between thigh muscle mass, insulin resistance, and incident type 2 diabetes mellitus (T2DM) risk. In addition, we examined the role of body mass index (BMI) as a potential effect modifier in this association. METHODS: This prospective study included 399 Japanese Americans without diabetes (mean age 51.6 years) who at baseline had an estimation of thigh muscle mass by computed tomography and at baseline and after 10 years of follow-up a 75-g oral glucose tolerance test and determination of homeostasis model assessment of insulin resistance (HOMA-IR). We fit regression models to examine the association between thigh muscle area and incidence of T2DM and change in HOMA-IR, both measured over 10 years. RESULTS: Thigh muscle area was inversely associated with future HOMA-IR after adjustment for age, sex, BMI, HOMA-IR, fasting plasma glucose, total abdominal fat area, and thigh subcutaneous fat area at baseline (P=0.033). The 10-year cumulative incidence of T2DM was 22.1%. A statistically significant interaction between thigh muscle area and BMI was observed, i.e., greater thigh muscle area was associated with lower risk of incident T2DM for subjects at lower levels of BMI, but this association diminished at higher BMI levels. CONCLUSION: Thigh muscle mass area was inversely associated with future insulin resistance. Greater thigh muscle area predicts a lower risk of incident T2DM for leaner Japanese Americans. PMID- 30302962 TI - Utility of Serum Albumin for Predicting Incident Metabolic Syndrome according to Hyperuricemia. AB - BACKGROUND: Serum albumin and uric acid have been positively linked to metabolic syndrome (MetS). However, the association of MetS incidence with the combination of uric acid and albumin levels has not been investigated. We explored the association of albumin and uric acid with the risk of incident MetS in populations divided according to the levels of these two parameters. METHODS: In this retrospective longitudinal study, 11,613 non-MetS participants were enrolled among 24,185 individuals who had undergone at least four annual check-ups between 2006 and 2012. The risk of incident MetS was analyzed according to four groups categorized by the sex-specific medians of serum albumin and uric acid. RESULTS: During 55,407 person-years of follow-up, 2,439 cases of MetS developed. The risk of incident MetS increased as the uric acid category advanced in individuals with lower or higher serum albumin categories with hazard ratios (HRs) of 1.386 (95% confidence interval [CI], 1.236 to 1.554) or 1.314 (95% CI, 1.167 to 1.480). However, the incidence of MetS increased with higher albumin levels only in participants in the lower uric acid category with a HR of 1.143 (95% CI, 1.010 to 1.294). CONCLUSION: Higher levels of albumin were associated with an increased risk of incident MetS only in individuals with lower uric acid whereas higher levels of uric acid were positively linked to risk of incident MetS regardless of albumin level. PMID- 30302963 TI - Proportion and Characteristics of the Subjects with Low Muscle Mass and Abdominal Obesity among the Newly Diagnosed and Drug-Naive Type 2 Diabetes Mellitus Patients. AB - BACKGROUND: Sarcopenic obesity (SO) is a serious public health concern, few studies have examined the clinical implications of SO in newly-diagnosed type 2 diabetes mellitus (T2DM) patients. We evaluated the prevalence of the newly diagnosed, drug-naive T2DM patients with low muscle mass with abdominal obesity and its association with insulin resistance and other diabetic complications. METHODS: We classified 233 drug-naive T2DM subjects into four groups according to abdominal obesity (waist circumference >=90 cm in men and >=85 cm in women) and low muscle mass status (appendicular skeletal muscle <7.0 kg/m2 for men and <5.4 kg/m2 for women). RESULTS: The proportion of the subjects with low muscle mass and abdominal obesity among the newly diagnosed, drug-naive T2DM patients was 8.2%. Homeostasis model assessment of insulin resistance (HOMA-IR) increased linearly according to body composition group from normal to abdominal obesity to both low muscle mass and abdominal obesity. The multiple logistic regression analysis indicated that subjects with low muscle mass and abdominal obesity (odds ratio [OR], 9.39; 95% confidence interval [CI], 2.41 to 36.56) showed a higher risk for insulin resistance, defined as HOMA-IR >=3, than those with abdominal obesity (OR, 5.36; 95% CI, 2.46 to 11.69), even after adjusting for other covariates. However, there were no differences in lipid profiles, microalbuminuria, or various surrogate markers for atherosclerosis among the four groups. CONCLUSION: Subjects with both low muscle mass and abdominal obesity had a higher risk of insulin resistance than those with low muscle mass or abdominal obesity only. PMID- 30302964 TI - Higher High Density Lipoprotein 2 (HDL2) to Total HDL Cholesterol Ratio Is Associated with a Lower Risk for Incident Hypertension. AB - BACKGROUND: Recent studies have suggested that high density lipoprotein (HDL) cholesterol is inversely associated with the development of hypertension. We aimed to determine the association between different HDL cholesterol subclasses and risk of future hypertension. METHODS: A total of 270 Japanese Americans (130 men, 140 women) without hypertension between the ages of 34 to 75 years were enrolled. Blood pressure was measured with a mercury sphygmomanometer, and average blood pressure was calculated. Incident hypertension was determined 5 to 6 and 10 to 11 years after enrollment. HDL2, HDL3, and total HDL cholesterol were measured at baseline. RESULTS: During 10 years of follow-up, the cumulative incidence of hypertension was 28.1% (76/270). In univariate analysis, age, diabetes, waist circumference, systolic and diastolic blood pressure, fasting glucose, insulin resistance index, total and low density lipoprotein cholesterol, and visceral adipose tissue were significant predictors for incident hypertension. Among the HDL cholesterol subclass, HDL2 cholesterol was inversely associated with hypertension incidence, but both total and HDL3 cholesterol were not. In addition, HDL2/HDL cholesterol was inversely associated with future hypertension risk. In multivariate analysis, age (odds ratio [OR], 1.71; 95% confidence interval [CI], 1.26 to 2.31; P=0.001), systolic blood pressure (OR, 1.83; 95% CI, 1.31 to 2.56; P<0.001), and HDL2/HDL cholesterol (OR, 0.71; 95% CI, 0.52 to 0.98; P=0.035), were associated with future development of hypertension. CONCLUSION: A higher proportion of HDL2 cholesterol among total HDL cholesterol predicted a lower risk for incident hypertension. However, concentrations of total HDL, HDL2, and HDL3 cholesterol were not independent predictors of incident hypertension. PMID- 30302965 TI - Cardiovascular Autonomic Neuropathy Predicts Higher HbA1c Variability in Subjects with Type 2 Diabetes Mellitus. AB - BACKGROUND: This study aimed to investigate the association between the presence and severity of cardiovascular autonomic neuropathy (CAN) and development of long term glucose fluctuation in subjects with type 2 diabetes mellitus. METHODS: In this retrospective cohort study, subjects with type 2 diabetes mellitus who received cardiovascular autonomic reflex tests (CARTs) at baseline and at least 4 year of follow-up with >=6 measures of glycosylated hemoglobin (HbA1c) were included. The severity of CAN was categorized as normal, early, or severe CAN according to the CARTs score. HbA1c variability was measured as the standard deviation (SD), coefficient of variation, and adjusted SD of serial HbA1c measurements. RESULTS: A total of 681 subjects were analyzed (294 normal, 318 early, and 69 severe CAN). The HbA1c variability index values showed a positive relationship with the severity of CAN. Multivariable logistic regression analysis showed that CAN was significantly associated with the risk of developing higher HbA1c variability (SD) after adjusting for age, sex, body mass index, diabetes duration, mean HbA1c, heart rate, glomerular filtration rate, diabetic retinopathy, coronary artery disease, insulin use, and antihypertensive medication (early CAN: odds ratio [OR], 1.65; 95% confidence interval [CI], 1.12 to 2.43) (severe CAN: OR, 2.86; 95% CI, 1.47 to 5.56). This association was more prominent in subjects who had a longer duration of diabetes (>10 years) and lower mean HbA1c (<7%). CONCLUSION: CAN is an independent risk factor for future higher HbA1c variability in subjects with type 2 diabetes mellitus. Tailored therapy for stabilizing glucose fluctuation should be emphasized in subjects with CAN. PMID- 30302966 TI - Soluble Dipeptidyl Peptidase-4 Levels Are Associated with Decreased Renal Function in Patients with Type 2 Diabetes Mellitus. AB - BACKGROUND: Dipeptidyl peptidase-4 (DPP-4) is strongly expressed in the kidney, and soluble levels of this protein are used as a marker in various chronic inflammatory diseases, including diabetes, coronary artery disease, and cancer. This study examined the association between the serum soluble DPP-4 levels and renal function or cardiovascular risk in patients with type 2 diabetes mellitus. METHODS: In this retrospective analysis, soluble DPP-4 levels were measured in preserved sera from 140 patients with type 2 diabetes mellitus who had participated in our previous coronary artery calcium (CAC) score study. RESULTS: The mean+/-standard deviation soluble DPP-4 levels in our study sample were 645+/ 152 ng/mL. Univariate analyses revealed significant correlations of soluble DPP-4 levels with the total cholesterol (r=0.214, P=0.019) and serum creatinine levels (r=-0.315, P<0.001) and the estimated glomerular filtration rate (eGFR; estimated using the modification of diet in renal disease equation) (r=0.303, P=0.001). The associations of soluble DPP-4 levels with serum creatinine and GFR remained significant after adjusting for age, body mass index, and duration of diabetes. However, no associations were observed between soluble DPP-4 levels and the body mass index, waist circumference, or CAC score. CONCLUSION: These data suggest the potential use of serum soluble DPP-4 levels as a future biomarker of deteriorated renal function in patients with type 2 diabetes mellitus. PMID- 30302967 TI - Three-dimensional quantitative phase imaging of blood coagulation structures by optical projection tomography in flow cytometry using digital holographic microscopy. AB - Blood coagulation is an important role in the hemostasis process. In the observation using microscopies, an aggregation structure of red blood cells indicates the degree of blood coagulation. Recently, it has been proposed that digital holographic microscopy (DHM) is a powerful tool for biomedical cell imaging on the basis of quantitative phase information. DHM has the advantage in that the real-time and three-dimensional (3-D) quantitative phase imaging can be realized in the wide field of view, which means that the 3-D morphological parameters of biological cells without a staining process are obtained in real time. We report the complete 3-D quantitative phase imaging of blood coagulation structures by optical projection tomography in a flow cytometry using DHM. PMID- 30302969 TI - Procedural Fairness and the Coroner. AB - The hearing rule of procedural fairness applies to coroners' investigations and the findings made by coroners. Decisions by Australian and New Zealand appellate courts starting from the 1980s and early 1990s suggest that this will require interested parties to be accorded the opportunity to respond to any adverse findings, and probably comments, which a coroner is minded to make by being alerted in advance to what is proposed by the coroner. This editorial scrutinises decisions by the Victorian Supreme Court and Court of Appeal on the issue between 2016 and 2018 against the backdrop of appellate decisions in South Australia and New Zealand, as well as in the context of the development of modern administrative law in both Australia and New Zealand. It identifies conceptual challenges that exist as a result of the recent case law for coroners' courts, pointing to the uncertainty of what are "adverse" findings and comments for these purposes, a lack of clarity as to who is entitled to procedural fairness in the inquisitorial context of a coronial investigation, the uncertain parameters of reputation for such purposes, vagueness as to what is required for coroners to discharge their obligations, and the logistical difficulties that compliance with such obligations will pose for timeliness of coronial findings. PMID- 30302968 TI - Holmium-YAG laser: impact of pulse energy and frequency on local fluid temperature in an in-vitro obstructed kidney calyx model. AB - During laser lithotripsy, energy is transmitted to both the stone and the surrounding fluid. As the energy is delivered, the temperature will rise. Temperatures >=60 degrees C can cause protein denaturation. The objective of this study is to determine the time it takes from body temperature (37 degrees C) to 60 degrees C at various laser power settings. A Flexiva TracTip 200 optical fiber was submerged alongside a negative temperature coefficient-type thermistor in 4 mL of saline in a glass test tube. A Lumenis VersaPulse Powersuite 100-W holmium:yttrium aluminum garnet laser was activated at 0.2- to 1.5-J pulse energies, 6- to 50-Hz frequencies, and 2- to 22.5-W average power. Temperature readings were recorded every second from 37 degrees C until 60 degrees C. Time and heating rate were measured. The procedure was repeated three times for each setting. Average time from 37 degrees C to 60 degrees C for settings (1) 0.2 J/50 Hz, (2) 0.6 J/6 Hz, (3) 1 J/10 Hz, and (4) 1.5 J/10 Hz was 60.3, 172.7, 58, and 43.3 s, respectively. Time from 37 degrees C to 60 degrees C decreased as frequency increased for every given pulse energy. Average heating rate increased proportionally to power from 0.06 degrees C/s at 2 W to 0.74 degrees C/s at 22.5 W. During laser lithotripsy, there is a rapid increase in the temperature of its surrounding fluid and temperatures >=60 degrees C may be reached. This could have local tissue effects and some caution with higher power settings should be employed especially where irrigation is limited. Further studies incorporating irrigation and live tissue models may aid to further define the risks.

AB - As a general rule, lawfulness of data processing under the European Union General Data Protection Regulation (EU 2016/679) (GDPR) is based on affirmative, unambiguous, voluntary, informed, and specific or "granular" consent to processing of their data, including health data, by individuals referred to as data subjects. The GDPR grants data subjects the legal right to specifically agree to (or refuse) having their data processed in any of the ways statutorily defined as "processing". Individuals also have the legal right to be fully informed about each and every intended use of their data by data processors and controllers, and the right to refuse such use. In Australia, once registered on the My Health Record (MHR) system, "healthcare recipients" as patients-cum-data subjects are called under the MHR scheme, have the right to remove documents from their MHR files and block some health care providers from accessing their data. However, this study demonstrates that the notion of "standing" consent that the MHR scheme appears to have created does not conform to any of the principles and rules governing data subjects' consent rights under GDPR. PMID- 30302971 TI - Geriatric Forensic Medicine - A Specialty that can no Longer Wait to be Realised. AB - The rise in the population and the growth in the proportion of the elderly in our population are changing the structure of many of our communities and placing increasing demands on our social and health care services. "Scandals" regarding conditions and standards of care in residential aged care facilities have raised concerns about the regulation, assessment and auditing of these community services for the elderly. At the same time longer working lives change the age factors related to employment opportunities and the cadre of older employees presents a different range of human resource issues and occupational health and safety problems for employers. While there is evidence that an older workforce can bring a wider experience and understanding of critical issues to many work disciplines, ageing practitioners may pose professional regulatory issues for the community when considerations of cognitive and technical/physical ability arise. It is in these settings that the need for a forensic focus on gerontology and medical geriatrics arises. PMID- 30302972 TI - "A Steadying Hand": Ascribing Speech Acts to Users of Predictive Speech Assistive Technologies. AB - Neuroprosthetic speech technologies are in development for patients suffering profound paralysis, such as can result from amyotrophic lateral sclerosis. These patients would be unable to speak without intervention, but with neurotechnology can be offered the chance to communicate. The nature of the technology introduces a neuroprosthesis that mediates neural activity to generate synthesised speech. How word prediction coheres with speaker intentions requires scrutiny. Some future forms of prostheses, using statistical language models to predict word patterns, could be thought of as participating with communicative intent - not merely channelling it. Concepts relating to vicarious liability, may serve to clarify these issues. This column shows how technology might interact with speaker intent in cases of delegated action, and how it should be seen as participating in the implementation of user "instructions".

AB - The first official pill testing at an Australian music festival was conducted at Groovin' The Moo in Canberra on 29 April 2018. As the trial was the first of its kind in Australia, it was not without legal hurdles and uncertainty. Primarily, there was concern over the legal consequences for patrons participating in the pill testing, as well as the legal liability of those facilitating and conducting the testing. This article will discuss the legal hurdles that were overcome in order to facilitate the trial, and the future consequences and position of pill testing at Australian festivals. PMID- 30302974 TI - Moritz Meyer and the Medical Board: Preventing Refugee Doctors from Practising Medicine in Victoria, Australia, 1937-1958. AB - In 1937, the Medical Board of Victoria (the Board) declined to register Moritz Meyer to practise medicine in Victoria, Australia. Meyer was a Jewish doctor who had completed his medical degree in Germany and obtained postgraduate qualifications in Scotland. Meyer successfully challenged the Board's decision in the Supreme Court of Victoria and the Board's appeal against that decision to the High Court of Australia, which was dismissed. In response to Meyer's victory, the Board, under the influence and together with the British Medical Association, successfully lobbied the Victorian Parliament to prevent doctors from practising medicine in Victoria unless they had completed their studies in Victoria or in a country in which Victorian doctors, by virtue of their registration in Victoria, were entitled to practise medicine. Meyer's case received substantial press coverage, but historians have referred to it only in passing. This article fills a notable gap in the historiography about this period by illuminating the significance of Meyer's matter. It analyses the decisions in this case and considers their impact on European doctors who sought refuge in Victoria immediately before, during and after World War II, and on the medical profession and lay community. It then seeks to explain these reactions to Meyer's matter. PMID- 30302975 TI - Does Disciplinary Law Protect Us from False and Misleading Health Advertising? AB - Health-related advertisements should not mislead prospective patients. To do so may deprive patients of their ability to give or withhold consent to treatment and in the case of terminally ill patients, of the opportunity to accept and come to terms with the dying process. Patients should be able to expect that claims in health-related advertising are based on the most recent scientific evidence and are not predatory or exploitative. However, internet advertising and social media continue to provide opportunities for unscrupulous health practitioners to peddle their wares. This article considers whether disciplinary law effectively deals with false, misleading or deceptive health-related advertising in the context of regulated and unregulated practitioners as well as complementary and alternative medicine. It argues that consideration should be given to amending disciplinary law to specify what evidence is required to substantiate claims made in advertising. PMID- 30302976 TI - National Competition Policy and Australia's Health Care System: A Look at the Policy Landscape with New Eyes. AB - Australia spends nearly 10% of its gross domestic product on health services. With such a substantial financial commitment, even relatively minor improvements in efficiency, effectiveness and productivity can increase community welfare. Competition is a well-recognised policy lever implemented to achieve these goals in market economies. However, it has for many years struggled to gain traction in the health care sector. This article traces recent attempts to promote competition principles in Australia's health care sector. Highlighting where these attempts have stalled, it compares Australia's recent health reforms with those instituted in the United Kingdom's National Health Service where a sector specific competition regulator has been in place for several years. It concludes that there is room in Australia's regulatory landscape to improve public reporting and increased choice in health care. A sector-specific regulator is envisaged to support these important competition-based initiatives. PMID- 30302977 TI - Dental Health Workforce Regulation - How Amendments to the Health Practitioner Regulation National Law Act May Shape the Future of the Dental Profession. AB - Recent amendments to the Health Practitioner Regulation National Law Act adopt a number of recommendations published in the final report of the Independent review of the National Registration and Accreditation Scheme. The adopted recommendations are of interest because of their potential effect on the regulation of the dental profession and how they demonstrate the potential attenuation of the influence of the health professions in general in the arena of healthcare regulation. The wide-reaching effects of these changes and the impact they may have on the future direction of the dental profession in Australia are still uncertain, but are sure to be significant. This article will consider the changing role of the Dental Board in regulation and health workforce reform and show that the Dental Board is no longer the driver of dental workforce policy but plays a subordinate role to facilitate and implement health policy on direction from the AHWMC. PMID- 30302978 TI - In Sickness and in Prison: The Case for Removing the Medicare Exclusion for Australian Prisoners. AB - Many current and former prisoners experience significantly higher rates of physical and mental health problems than others in the community, and are among the most marginalised and disadvantaged people in society. This article argues that granting prison health services an exemption under s 19(2) of the Health Insurance Act 1973 Cth would make the Medicare Benefits Schedule and the Pharmaceutical Benefits Scheme-funded services available to prisoners who meet the eligibility criteria. Australian prisoners would then receive a level of care at least equivalent to that offered by community health services. Reducing health inequities that prisoners experience, particularly Indigenous prisoners, is essential for them continuing to receive health care following release and successfully reintegrating into the community. Further, granting the exemption would assist the Australian Government to meet its international human rights obligations to provide equitable health care for all Australians. PMID- 30302979 TI - "Mental Disorder" and Sentencing: Resolving the Definitional Problem. AB - Mental health problems affect the majority of people who face the sentencing process. The fact that a convicted offender has mental health problems may be taken into account in various ways: it may mitigate or aggravate the penalty, or may affect the type of sanction that is imposed or its conditions. At present, sentencing judges use a two-stage process to determine the effect (if any) that an offender's mental health problems should have on the sentencing determination. First, they ascertain whether the offender has a relevant mental health problem. If they find that he or she does, they then decide what effect that mental health problem should have on the sentencing determination. This article compares recent approaches that have been taken to the first stage of this process in Australia and Canada. It highlights difficulties with both approaches, and recommends replacing the current two-stage process with an integrated, single-stage approach. PMID- 30302980 TI - Biologics and Public Health: Prospects and Challenges. AB - Biotechnology has been used by humankind for thousands of years and it remains a very important part of human medicine. Biotechnology is particularly relevant to the creation of new medicines and vaccines. Biotechnology drugs or biologics are becoming increasingly popular in the life sciences sector. Biologics were estimated to account for US$289 billion pharmaceutical sales in 2014 and are projected to reach US$445 billion in 2019. It is also anticipated that biologics' share of global prescription and over-the-counter pharmaceutical sales will rise to 26% by 2019. Biological medicines are capable of being developed to cure life threatening diseases that used to be completely incurable. While biologics have unprecedented therapeutic effects, though, they also raise significant quality and patient safety issues. This article discusses some of the regulatory challenges relating to biologics. It also explores mechanisms that may be adopted to promote the development of new biologics and access to biological drugs especially in low income countries.

AB - This article examines the Australian approach to handling the complex privacy issues raised by Big Data analytics in health research. It analyses the privacy challenges posed by Big Data analytics and considers the privacy-related issues pertaining to the secondary use of health data for research purposes. It also examines the Australian regulatory regimes governing secondary uses of health data for research purposes contained in privacy legislation and human research guidelines, and includes a critique of a new criminal offence for re identification of de-identified datasets proposed by the Australian Government. The article concludes with suggestions for a reform process that enables responsible research into big health data while properly addressing the protection of privacy and confidentiality of such data. PMID- 30302982 TI - Australian Public Attitudes on Gene Editing of the Human Embryo. AB - Technology is now available which facilitates gene editing and has recently been applied internationally to embryos in the laboratory. A 2002 law in Australia prohibits making heritable changes in embryos, regardless of whether the treated embryo is discarded thereafter. We sought to begin to understand public opinion in Australia about this matter, using a questionnaire given to the audience attending a Q and A panel of experts. We found majority support for allowing heritable changes for health purposes. If this is confirmed in a larger survey of the population, we suggest the existing law should be reviewed. PMID- 30302983 TI - Regulating RNA Research and CRISPR Gene Drives to Combat Biosecurity Threats. AB - Recent technological breakthroughs in ribonucleic acid (RNA) research and the creation of synthetic gene drives using CRISPR/Cas9 have increased attention on the ethical and legal regulation of this field. RNA is now perceived as not merely a passive carrier of DNA information but especially through its propensity to mutate as a computation engine of cell biology, developmental biology and evolution. Synthetic Gene drives have been hailed as a potential strategy to reduce climate-change-mediated biosecurity threats such as spreading malaria and have attracted significant investment, with the Gates Foundation pledging US$75 million and the Defense Advanced Research Projects Agency awarding US$65 million. Calls for a global moratorium on RNA-mediated genetic engineering may overstate the potential risks of the developing technology, but form a background to the contest between "process"- and "product" -based approaches to regulation, the former purportedly favoured by the public and regulatory agencies and the latter favoured by the broad scientific community and corporate investors. At stake may be the democratic legitimacy of and equitable access to a technology that could be important to reduce the incidence of biosecurity threats both globally and in Australia. PMID- 30302984 TI - Providing Palliative Care at the End of Life: Should Health Professionals Fear Regulation? AB - Anecdotal evidence from Australia and abroad suggests that health professionals may fear potential legal and/or professional repercussions if their patient dies after receiving pain relieving medication at the end of life. As a result, patients may be under-medicated and their pain and other symptoms not adequately relieved. The regulatory repercussions from inappropriate administration of medications are potentially broad and include criminal charges, civil negligence claims, coronial investigations and disciplinary proceedings. But despite these potentially serious repercussions, a review of publicly available cases in Australia reveals there has been comparatively little judicial or quasi-judicial scrutiny where over-medication is alleged to have resulted in a patient's death. In this article, we describe the regulatory framework that governs this field of medical practice and analyse the extent to which the actions of health professionals have been scrutinised, and the consequences of that scrutiny. We identify a number of themes arising from this analysis and conclude that fears of legal or professional repercussions are largely unfounded, and that existing laws and other forms of regulation should not inhibit the prescription and administration of adequate pain and other symptom relief to people at the end of life. PMID- 30302985 TI - The Role of the Medical Profession in Victorian Assisted Dying Law Reform. AB - The Voluntary Assisted Dying Act Vic will commence operation on 19 June 2019. Doctors were highly visible in the debate which informed the recent law reform process, and Victorian legislators relied considerably on the diverse views of the medical profession. It is important to pay attention to the role played by doctors in the legalisation of assisted dying in Victoria, not only because the current political environment suggests that further reforms may be likely in other Australian jurisdictions, but also because doctors' knowledge and expertise visibly contributed to the outcome of that process in Victoria. This article aims to map the participation of doctors in the recent law reform process to analyse how their professional attributes positioned them in the Victorian assisted dying space. It is suggested that doctors were afforded a place in law reform because of the routine acceptance of doctors as knowledge keepers in matters of life and death and an acknowledgment of the integral role of medical expertise in the legislation. A textual analysis of the Hansard record of the Victorian debate reflects that individual practitioner advocacy for legalisation prevailed over opposition by the national branch of the Australian Medical Association in the deliberations of parliamentarians. PMID- 30302986 TI - Sexual Assault Examination of the Unconscious Patient: A Legal, Ethical and Professional Grey-area for the Forensic Physician. AB - When treating unconscious patients believed to have been victims of sexual assault, forensic physicians must decide whether to conduct physical examinations in order to collect evidence while patients are unconscious and cannot consent. The choice is urgent: potential evidence may be lost before the patient regains the ability to consent. The physician's choice affects not only the patient's bodily integrity, but also their ability to pursue criminal and potentially civil justice remedies if they were assaulted. This article bases its discussion on one such real-life situation. It first examines ethical models relevant to deciding whether to take evidence and finds that no one approach produces morally satisfactory outcomes in every case. It then examines the legal framework guiding these decisions, finding that while collecting evidence without consent may well be permissible under New South Wales (NSW) legislation, relevant guidelines disallow it, placing physicians in a legal grey-area. The article concludes with practical recommendations to address these ethical, professional and legal challenges. PMID- 30302987 TI - Proteinuria in children with autosomal dominant polycystic kidney disease. AB - BACKGROUND: Proteinuria is a common complication in adults with autosomal dominant polycystic kidney disease (ADPKD) and serves as a risk factor for progression. However, proteinuria has rarely been examined in children with ADPKD and the type of proteinuria has not yet been investigated. The aim of the study was to assess the prevalence and to analyse the types of proteinuria in children with ADPKD. METHODS: Children with ADPKD followed-up in our tertiary centres during the years 2012-2013 were investigated in a cross-sectional study. Morning urine was tested for total protein (PROT), albumin (ALB) and alpha-1 microglobulin (AMG). Renal function was assessed from serum creatinine as estimated glomerular filtration rate. RESULTS: Thirty-seven children of median age 11.2 (2.0-18.0) years were investigated. Median (range) PROT, ALB and AMG (in mg/mmol creatinine) were 15.1 (6.2-64.8), 2.54 (0.54-37.25) and 3.22 (0.04 10.16), respectively. Pathological total proteinuria (>22) was found in 30% of children, albuminuria (>2.2) in 49% of children and alpha-1-microglobulinuria (>0.55) in 65% of children. No correlation was found between PROT, ALB or AMG and office blood pressure, kidney size or estimated glomerular filtration rate. CONCLUSIONS: Proteinuria in children with ADPKD is a frequent finding, the most common type is tubular proteinuria. It should be measured in all ADPKD children. PMID- 30302988 TI - Mononucleosis-related fatigue: supplementary management with Robuvit(r). AB - BACKGROUND: Infectious mononucleosis (IM) is a common disease of adolescents and young adults, characterized by a specific triad of symptoms represented by fever, sore throat and lymphadenopathy. IM may also affect older adults, with different, more intense signs and symptoms such as fatigue, general malaise, and diffuse body pain. The aim of thisfour-week-registry study was to evaluate the effects of Robuvit(r) supplementation on the main consequences of mononucleosis, particularly fatigue, in otherwise healthy adults. METHODS: All patients enrolled in this registry study experienced an episode of IM characterized by fatigue, a general feeling of unwellness, diffuse body and muscular pain, leukocytosis, and high levels of oxidative stress, at least 2 to 4 weeks prior to inclusion. Fever had already resolved at inclusion. All included patients were positively tested for the Epstein-Barr virus (EBV). Subjects were divided in two groups: those receiving the standard management (SM, N.=26; vitamin B, C, and D, balanced healthy diet, regular sleeping schedule, physical activity, 2 mg copper), and those treated with SM plus Robuvit(r) (N.=24) supplementation (300 mg/day). RESULTS: Supplementation with Robuvit(r) was safe, overall tolerability was good, and no side effects were reported. All patients completed the four-week treatment. After 4 weeks of treatment, a significant reduction in the rate of symptoms was evident in the Robuvit(r) group compared to the control group (P<0.05). CONCLUSIONS: Supplementation with Robuvit(r) is safe, well tolerated, and effective in controlling oxidative stress levels and improving fatigue and other symptoms related to IM episodes during the convalescence period.

PMID- 30302996 TI - Phthalate and Organophosphate Plasticizers in Nail Polish: Evaluation of Labels and Ingredients. AB - In the 2000s, nail polish manufacturers started promoting "3-Free" products, phasing out three widely publicized toxic chemicals: toluene, formaldehyde, and dibutyl phthalate (DnBP). However, DnBP was sometimes replaced by another endocrine-disrupting plasticizer, triphenyl phosphate (TPHP). Many new " n-Free" labels have since appeared, without any standardization on which n chemicals are excluded. This study aimed to compare measured plasticizer content against nail polish labels. First, we summarized definitions of labels. Then, we measured 12 phthalate and 10 organophosphate plasticizers in 40 nail polishes from 12 brands selected for popularity and label variety. We found labels ranging from 3- to 13 Free; 10-Free was the most inconsistently defined (six definitions). Our samples contained TPHP and bis(2-ethylhexyl) phthalate (DEHP) at up to 7940 and 331 MUg/g, respectively. The 5- to 13-Free samples had lower TPHP levels than unlabeled or 3-Free samples (median <0.002 vs 3730 MUg/g, p < 0.001). The samples that did not contain TPHP had higher DEHP levels (median 68.5 vs 1.51 MUg/g, p < 0.05). We measured plasticizers above 100 MUg/g in five brands that did not disclose them and in two that excluded them in labels. This study highlights inconsistencies in nail polish labels and identifies TPHP and DEHP as ingredient substitutes for DnBP. PMID- 30302997 TI - Computation-Aided Design of Single-Atom Catalysts for One-Pot CO2 Capture, Activation, and Conversion. AB - Lowering the concentration of CO2 in atmosphere is a global concern but yet remains one of the most challenging processes in chemistry. Herein, we report a rational design of single-atom catalyst (SAC), namely, vanadium atom supported on newly synthesized beta12 boron monolayer (V1/beta12-BM), for one-pot CO2 capture, activation, and efficient conversion into methanol. Our first-principles computations reveal that strong interaction ensures V1/beta12-BM can capture CO2 at ambient and elevated temperatures. Substantial charge transfer between V1/beta12-BM and CO2 triggers the activation of CO2 into anionic CO2-, which can be efficiently hydrogenated into CH3OH with an ultralow limiting potential of 0.54 V and a rather low rate-determining barrier of 1.04 eV. Moreover, the adsorption of H2O molecules can make the reaction intermediates closer to the hydrogen source by the steric hindrance, which plays a key role in lowering the reaction barrier. Our findings present the first SAC for one-pot CO2 capture, activation, and conversion, which may open a new avenue for recycling CO2.

Their structures were elucidated by detailed HPLC-HR-MS/MS analysis and confirmed by chemical synthesis. Bioactivity tests of these first rhabdopeptide/xenortide-like peptide derivatives (2-7) showing methionine building blocks compared to the usually found derivatives containing exclusively hydrophobic amino acids such as valine, leucine, or phenylalanine revealed good activities of 2-7 against protozoan parasites and no cytotoxicity against mammalian L6 cells.

Particular attention is paid to both foundational studies and recent advances over the past decade involving semistabilized and nonstabilized 2-azaallyl anions as key intermediates in various carbon-carbon and carbon-heteroatom bond-forming processes. Both transition-metal-catalyzed and transition-metal-free transformations are covered.

Unlike other boronate-reactive oxygen species (ROS) fluorogenic probes that are oxidized by HOCl through a nucleophilic borono Dakin oxidation mechanism, probe 4 is distinguished by its electrophilic oxidation mechanism involving B-H bond cleavage. Two-photon microscopy experiments in living cells and tissues with the probe 4 demonstrate the monitoring of endogenous HOCl generation and changes in HOCl concentrations generated in the endoplasmic reticulum during oxidative stress situations. PMID- 30303001 TI - Circular Dichroism Photoswitching with a Twist: Axially Chiral Hemiindigo. AB - Chiroptical properties play a crucial role not only for molecular structures and their functions but also for advanced applications such as molecular sensing, absolute asymmetric synthesis, or information processing and storage. Manipulating chiroptical characteristics in a predictable and reversible fashion by outside means is therefore a highly desirable option to enhance the functions and reporting abilities of a molecular system. Herein, we present axially chiral hemiindigo photoswitches showing unusual chiroptical changes upon visible-light irradiation. While absorption remains high throughout the spectrum, the corresponding ECD signals can be reversibly erased and reestablished in an ON/OFF manner upon photoswitching. Taken together with exceptionally high thermal bistabilities, leading to half-lives of the metastable states up to 3400 years at ambient temperature, and high photoswitching quantum yields these chiral hemiindigos offer unique possibilities for, e.g., smart molecule, photonic materials, or sensing applications. PMID- 30303002 TI - Ancistrolikokine E3, a 5,8'-Coupled Naphthylisoquinoline Alkaloid, Eliminates the Tolerance of Cancer Cells to Nutrition Starvation by Inhibition of the Akt/mTOR/Autophagy Signaling Pathway. AB - PANC-1 human pancreatic cancer cells are characterized by their ability to proliferate aggressively under hypovascular and hypoxic conditions in the tumor microenvironment, displaying a remarkable tolerance to nutrition starvation. The antiausterity strategy is a new approach in anticancer drug discovery aiming at the identification of potent agents that inhibit preferentially the survival of tumor cells during a limited supply of nutrients and oxygen. The new 5,8'-coupled naphthyldihydroisoquinoline alkaloid ancistrolikokine E3 (4), isolated from the Congolese liana Ancistrocladus likoko, showed potent preferential cytotoxicity against PANC-1 cells under nutrient-deprived conditions, with a PC50 value of 2.5 MUM, without exhibiting toxicity in normal, nutrient-rich medium. The compound was found to induce dramatic alterations in cell morphology, leading to cell death. Moreover, it inhibited significantly PANC-1 cell migration and colony formation in a concentration-dependent manner. This study on 4 provides the first live evidence of the effect of a naphthyldihydroisoquinoline alkaloid against PANC-1 cells in nutrient-deprived medium. Mechanistic investigations conducted suggest that compound 4 is a potent inhibitor of the activation of the Akt/mTOR pathway. Furthermore, it inhibited the expression levels of the key autophagy regulators Atg5, Atg12, Beclin-1, LC3-I, and LC3-II. The results demonstrated that ancistrolikokine E3 (4) is a potent early-stage inhibitor of the autophagy pathway in PANC-1 human pancreatic cancer cells. Ancistrolikokine E3 (4) and related naphthylisoquinoline alkaloids are promising potential lead compounds for anticancer drug development based on the antiausterity strategy. PMID- 30303003 TI - Boosting Tunable Syngas Formation via Electrochemical CO2 Reduction on Cu/In2O3 Core/Shell Nanoparticles. AB - In this work, monodisperse core/shell Cu/In2O3 nanoparticles (NPs) were developed to boost efficient and tunable syngas formation via electrochemical CO2 reduction for the first time. The efficiency and composition of syngas production on the developed carbon-supported Cu/In2O3 catalysts are highly dependent on the In2O3 shell thickness (0.4-1.5 nm). As a result, a wide H2/CO ratio (4/1 to 0.4/1) was achieved on the Cu/In2O3 catalysts by controlling the shell thickness and the applied potential (from -0.4 to -0.9 V vs reversible hydrogen electrode), with Faraday efficiency of syngas formation larger than 90%. Specifically, the best performing Cu/In2O3 catalyst demonstrates remarkably large current densities under low overpotentials (4.6 and 12.7 mA/cm2 at -0.6 and -0.9 V, respectively), which are competitive with most of the reported systems for syngas formation. Mechanistic discussion implicates that the synergistic effect between lattice compression and Cu doping in the In2O3 shell may enhance the binding of *COOH on the Cu/In2O3 NP surface, leading to the enhanced CO generation relative to Cu and In2O3 catalysts. This report demonstrates a new strategy to realize efficient and tunable syngas formation via rationally designed core/shell catalyst configuration.

In this paper, the ultrathin Cu(I)/Cu(II) inorganic coordination polymer quantum sheet (ICPQS) {[CuII(H2O)4][CuI4(CN)6]} n is synthesized by controlling the appropriate molar ratio of raw material, reaction time, and temperature. Transmission electron microscopy (TEM) and atomic force microscope (AFM) analysis show that this ICPQS has a thickness of ~0.2 nm. Due to the fact that about 58.16% of the Cu(I)/Cu(II) is occupied in molecular structure and most of the metal active sites are fully utilized, this ICPQS can accelerate the photocatalytic degradation of methylene blue (MB) (K = 2.5 mg.L-1.min-1 at pH 3) and organic compounds in coking wastewater and biotreated coking wastewater. Basing on mixed valences, the ICPQS can use visible light to promote energy transfer and increase quantum efficiency, paving the way for developing the next-generation monolayer 2D mixed valence photocatalysts.

AB - The major product of the reaction between Ru(IMe4)2(PPh3)2H2 (1; IMe4 = 1,3,4,5 tetramethylimidazol-2-ylidene) and P(C6F5)3 (PCF) is the five-coordinate complex Ru(IMe4)2(PF2{C6F5})(C6F5)H (2), which is formed via a complex series of C-F/P-C bond cleavage and P-F bond formation steps. In contrast, hydrodefluorination of all six ortho C-F bonds in PCF occurs with Ru(PPh3)4H2 to afford Ru(PPh3)3HF (3). NaBArF4 abstracted the fluoride ligand in 3 to give [Ru({eta6 C6H5}PPh2)(PPh3)2H][BArF4], while B2pin2 reacted with 3 in C6D6 to yield a mixture of [Ru({eta6-C6D6)(PPh3)2H]+ and Ru(PPh3)4H2. The treatment of 3 with HBpin (5 equiv) and HSiR3 (R = Et, Ph; 2 equiv) afforded Ru(PPh3)3(sigma-HBpin)H2 and Ru(PPh3)3(SiR3)3H3, respectively. No stable substitution products were generated when 3 was reacted with Me3SiX (X = CF3, C6F5). PMID- 30303006 TI - DNA Polymer Nanoparticles Programmed via Supersandwich Hybridization for Imaging and Therapy of Cancer Cells. AB - Spherical nucleic acid (SNA) constructs are promising new single entity materials, which possess significant advantages in biological applications. Current SNA-based drug delivery system typically employed single-layered ss- or ds-DNA as the drug carriers, resulting in limited drug payload capacity and disease treatment. To advance corresponding applications, we developed a novel DNA-programmed polymeric SNA, a long concatamer DNA polymer that is uniformly distributed on gold nanoparticles (AuNPs), by self-assembling from two short alternating DNA building blocks upon initiation of immobilized capture probes on AuNPs, through a supersandwich hybridization reaction. The long DNA concatamer of polymeric SNA enables to allow high-capacity loading of bioimaging and therapeutics agents. We demonstrated that both of the fluorescence signals and therapeutic efficacy were effectively inhibited in resultant polymeric SNA. By further modifying with the nucleolin-targeting aptamer AS1411, this polymeric SNA could be specifically internalized into the tumor cells through nucleolin mediated endocytosis and then interact with endogenous ATP to cause the release of therapeutics agents from long DNA concatamer via a structure switching, leading to the activation of the fluorescence and selective synergistic chemotherapy and photodynamic therapy. This nanostructure can afford a promising targeted drug transport platform for activatable cancer theranostics. PMID- 30303007 TI - Strategy for the Realization of Highly Efficient Solution-Processed All Fluorescence White OLEDs-Encapsulated Thermally Activated Delayed Fluorescent Yellow Emitters. AB - Fabrication of highly efficient all thermally activated delayed fluorescence (TADF) white organic light-emitting diodes (WOLEDs) through solution-process still remains a big challenge. Here, two encapsulated TADF molecules with a small singlet-triplet energy gap (Delta EST) and high photoluminescence quantum yield (PLQY) were designed and synthesized as yellow emitters for solution-processed WOLEDs. The high current, power, and external quantum efficiencies of 41.6 cd A 1, 30.4 lm W-1, and 17.3% were achieved for the solution-processed all fluorescence WOLEDs with a single-emission layer. In contrast, even with the same Delta EST and PLQY, the corresponding unencapsulated parent emitters will account for nearly 50% loss of the potential device efficiency. This is for the first time that the small molecular TADF blue host and TADF yellow guest are used to construct solution-processed all-fluorescence WOLEDs, which exhibit high efficiency comparable with most of the vacuum-deposited all-fluorescence white devices. These results not only demonstrate the great potential of TADF emitters in achieving highly efficient solution-processed WOLEDs, but also testify the key role of molecular encapsulation in reducing polar-exciton quenching and enhancing electroluminescence performance.

PMID- 30303009 TI - Co2B and Co Nanoparticles Immobilized on the N-B-Doped Carbon Derived from Nano B4C for Efficient Catalysis of Oxygen Evolution, Hydrogen Evolution, and Oxygen Reduction Reactions. AB - A novel hybrid electrocatalyst of Co2B and Co nanoparticles immobilized on N-B doped carbon derived from nano-B4C (Co2B/Co/N-B-C/B4C) is in situ synthesized by pyrolysis of nano-B4C supporting Co(OH)2 nanoparticles with melamine. The Co2B and Co nanoparticles are formed and anchored on the generated N and B codoped carbon and undecomposed B4C. The hybrid exhibits remarkable catalytic performances toward the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR)-a very small potential of 1.53 V at 10 mA cm-2 for the OER and a high catalytic kinetics and superior durability for the ORR-which are superior to the RuO2 and Pt/C catalyst, respectively. Most impressively, the hybrid delivers a very small potential gap of 710 mV, which is lower than those of most bifunctional electrocatalysts reported. In addition, the hybrid also shows a satisfying hydrogen evolution reaction performance offering a small overpotential of 220 mV at 10 mA cm-2 and wonderful stability. The excellent trifunctional catalytic performances issue from synergetic effects of Co2B, metal Co, Co/N doped carbon, and B self-doped carbon coexisting in the hybrid with good interaction mutually. This work provides a new-type efficient multifunctional catalyst for regenerative fuel cell and overall water-splitting technologies. PMID- 30303010 TI - Preparation of Bi0.15Fe0.15TiO2 Nanocomposites for the Highly Selective Enrichment of Phosphopeptides. AB - Novel Bi0.15Fe0.15TiO2 nanocomposites (B0.15F0.15TNs) were synthesized for the first time by a modified sol-gel technology and successfully applied to selective extraction and enrichment of phosphopeptides from digested protein mixture solutions and real samples (tissue protein extract from human liver). The codoping of Bi and Fe into TiO2 results in a significant enhancement in both the enrichment efficiency and selectivity. Compared with the commercial available TiO2 extractant, the proposed B0.15F0.15TNs possess a lower detection limit (2 * 10-9 M) and higher selectivity at a low weight ratio of 1:1200 (phosphopeptides/nonphosphopeptides). Additionally, a total of 223 phosphorylation sites were identified from the human liver lysate after enrichment by the B0.15F0.15TNs. In addition, the synthesis of B0.15F0.15TNs is quite easy, of high yield, and inexpensive. PMID- 30303011 TI - Hongyacha, a Naturally Caffeine-Free Tea Plant from Fujian, China. AB - Hongyacha (HYC) is a type of new wild tea plant discovered in Fujian Province, China. This tea is helpful to the healing or prevention of disease in its original growing area. However, research on this tea is limited. Our results showed that HYC displayed obvious differences in its morphological characteristics compared with Cocoa tea ( Camellia ptilophylla Chang), a famous caffeine-free tea plant in China. Theobromine and trans-catechins, but not caffeine and cis-catechins, were the dominant purine alkaloids and catechins detected in HYC. HYC might contain abundant gallocatechin-(4 -> 8)-gallocatechin gallate, 1,3,4,6-tetra- O-galloyl-beta-d-glucopyranose, and (-)-gallocatechin-3,5 di- O-gallate, which were not detected in regular tea. We also found that the TCS1 of HYC was distinct, and the responding recombinant protein exhibited only theobromine synthase activity. The obtained results showed that HYC is a new kind of caffeine-free tea plant and may be used for scientific protection and efficient utilization in the future.

AB - The absorption of a 5-hydroxymethylfurfural (HMF)-cysteine adduct, 1 dicysteinethioacetal-5-hydroxymethylfurfural (DCH), and its effect on antioxidant activity and gut microbiota were investigated. Results indicated that DCH is more easily absorbed in rats than HMF. Serum DCH concentrations were 15-38-fold of HMF concentrations from 30 to 180 min after intragastrical administration at the level of 100 mg/kg of body weight, and 2.7-4.5% of absorbed DCH was converted to HMF. The malondialdehyde content in the plasma, heart, liver, and kidneys significantly increased after drug (100 mg/kg of bw) administration for 1 week, suggesting that HMF and DCH were oxidative-stress-inducing agents, instead of antioxidant agents, in rats. HMF and DCH also modulated gut microbiota. HMF promoted the growth of Lactobacillus, Tyzzerella, Enterobacter, and Streptococcus. DCH increased the ratio of Firmicutes/ Bacteroidetes and promoted the growth of Akkermansia, Shigella, and Escherichia while inhibiting the growth of Lactobacillus. PMID- 30303014 TI - Toxicokinetics and Metabolism of 3-Monochloropropane 1,2-Diol Dipalmitate in Sprague Dawley Rats. AB - Fatty acid esters of 3-monochloropropane 1,2-diol (3-MCPD) are a group of processing-induced toxicants. To better clarify their possible toxicological effects and mechanisms, it is important to investigate their absorption, distribution, metabolism, and excretion. In this study, the kinetic parameters of 3-MCPD dipalmitate in Sprague Dawley (SD) rat plasma were determined using ultraperformance liquid chromatography-triple quadrupole mass spectrometry. 3 MCPD dipalmitate was absorbed in rats with a Cmax of 135.00 ng/mL, a T1/2 of 3.87 h, a Tmax of 2.5 h, an MRT of 5.08 h, a CL of 3.50 L/h/g, a Vd of 21.34 L/g, and an AUC0-infinity of 458.47 h.ng/mL. A total of 17 metabolites were identified, and 16 of them were reported for the first time. Furthermore, these metabolites were examined for their presences in the liver, kidney, testis, brain, spleen, thymus, intestine, plasma, feces, and urine samples 2, 6, 12, 24, and 48 h after oral administration of 3-MCPD dipalmitate using Metabolynx software. PMID- 30303015 TI - One-Pot Synthesis of 3-Difluoromethyl Benzoxazole-2-thiones. AB - A one-pot strategy for the diversified synthesis of 3-difluoromethyl benzoxazole 2-thiones is reported. The reaction of 2-aminophenol, sodium chlorodifluoroacetate, and elemental sulfur in the presence of NaO t-Bu gives exclusively 3-difluoromethyl benzoxazole-2-thiones in good yield (up to 98%). The mechanism of this reaction presumably involves first cyclization of 2 aminophenols with thiocarbonyl fluoride, followed by N-difluoromethylation with difluorocarbene. The developed synthetic procedures are versatile, robust, and easily scalable for the synthesis of 3-difluoromethyl benzoxazole-2-thione derivatives, some of which have shown insecticidal activities.

The reaction undergoes a reaction mechanism involving consecutive gamma-addition-aldol reaction. PMID- 30303017 TI - Appraisals of dependent stressor controllability and severity are associated with depression and anxiety symptoms in youth. AB - BACKGROUND AND OBJECTIVES: Stress is well established as a strong risk factor for internalizing psychopathology. Learned helplessness research demonstrates that perceived controllability of stressors affects internalizing symptoms. Furthermore, subjective perceived stress is associated with psychopathology. However, most recent research has focused on measuring the frequency and expert rated severity of stressful life events despite evidence for the importance of stress perceptions. The present study brings together past and current literatures to investigate the importance of perceived severity and controllability of recent life events in the association between stressors and internalizing symptoms. DESIGN AND METHODS: We used a revised version of the Adolescent Life Events Questionnaire (ALEQ) that asked participants (ages 13-22, N = 328) to rate the frequency of 65 stressful events typical to youth, as well as the perceived stressfulness and control they felt over each event. Events were categorized prior to analysis as dependent (self-generated), independent (fateful) or neither. RESULTS: Controllability and severity appraisals were associated with depression and anxiety symptoms, controlling for stressor frequency (which also predicted symptoms), for dependent but not independent stressors. CONCLUSIONS: These results highlight the importance of controllability and severity appraisals as potential risk factors for internalizing disorders, exposing a potential target for therapy. PMID- 30303018 TI - Pleiotropy of the Drosophila melanogaster foraging gene on larval feeding-related traits. AB - Little is known about the molecular underpinning of behavioral pleiotropy. The Drosophila melanogaster foraging gene is highly pleiotropic, affecting many independent larval and adult phenotypes. Included in foraging's multiple phenotypes are larval foraging path length, triglyceride levels, and food intake. foraging has a complex structure with four promoters and 21 transcripts that encode nine protein isoforms of a cGMP dependent protein kinase (PKG). We examined if foraging's complex molecular structure underlies the behavioral pleiotropy associated with this gene. Using a promotor analysis strategy, we cloned DNA fragments upstream of each of foraging's transcription start sites and generated four separate forpr-Gal4s. Supporting our hypothesis of modular function, they had discrete, restricted expression patterns throughout the larva. In the CNS, forpr1-Gal4 and forpr4-Gal4 were expressed in neurons while forpr2 Gal4 and forpr3-Gal4 were expressed in glia cells. In the gastric system, forpr1 Gal4 and forpr3-Gal4 were expressed in enteroendocrine cells of the midgut while forpr2-Gal4 was expressed in the stem cells of the midgut. forpr3-Gal4 was expressed in the midgut enterocytes, and midgut and hindgut visceral muscle. forpr4-Gal4's gastric system expression was restricted to the hindgut. We also found promoter specific expression in the larval fat body, salivary glands, and body muscle. The modularity of foraging's molecular structure was also apparent in the phenotypic rescues. We rescued larval path length, triglyceride levels (bordered on significance), and food intake of for0 null larvae using different forpr-Gal4s to drive UAS-forcDNA. In a foraging null genetic background, forpr1 Gal4 was the only promoter driven Gal4 to rescue larval path length, forpr3-Gal4 altered triglyceride levels, and forpr4-Gal4 rescued food intake. Our results refine the spatial expression responsible for foraging's associated phenotypes, as well as the sub-regions of the locus responsible for their expression. foraging's pleiotropy arises at least in part from the individual contributions of its four promoters.

AB - Genital surgery in children with ambiguous or atypical genitalia has been marred by controversies about the appropriateness and timing of surgery, generating clinical uncertainty about decision making. Since 2006, medical experts and patient advocates have argued for putting the child's needs central as patient centered care. Based on audio recordings of 31 parent-clinician interactions in three clinics of disorders of sex development, we analyze how parents and clinicians decide on genital surgery. We find that clinicians and parents aim for parent-centered rather than infant-centered care. Parents receive ambivalent messages about surgery: while clinicians express caution, they also present the surgery as beneficial. We examine how parents and clinicians reach agreement about surgery-differentiating parents who push strongly for surgery from parents who do not express any preconceived preferences about surgery and parents who resist surgery. We conclude that clinicians use clinical uncertainty about surgery strategically to direct parents toward perceived clinically appropriate decisions. PMID- 30303022 TI - Cost-effectiveness of pembrolizumab versus brentuximab vedotin for patients with relapsed or refractory classical Hodgkin's lymphoma: a United States payer perspective. AB - AIMS: Patients with classical Hodgkin's lymphoma (cHL) who have relapsed after or are ineligible for autologous stem cell transplantation (ASCT) have limited treatment options and generally a poor prognosis. Pembrolizumab was recently approved in the US for the treatment of such patients having demonstrated clinical benefit and tolerability in relapsed/refractory cHL; however, the cost effectiveness of pembrolizumab in this population is currently unknown. MATERIALS AND METHODS: A three-state Markov model (progression-free [PF], progressed disease, and death) was developed to assess the cost-effectiveness of pembrolizumab (200 mg) vs brentuximab vedotin (BV; 1.8 mg/kg) in patients with relapsed/refractory cHL after ASCT who have not received BV post-ASCT over a 20 year time horizon from a US payer perspective. PF survival was modeled using a naive indirect treatment comparison of data from KEYNOTE-087 and the SG035-003 trial. Post-progression survival was modeled using data from published literature. Costs (drug acquisition and administration, disease management, subsequent treatment, and adverse events) and outcomes were discounted at an annual rate of 3.0%. Uncertainty surrounding cost-effectiveness was assessed via probabilistic, deterministic, and scenario analyses. RESULTS: In the base case, pembrolizumab was predicted to yield an additional 0.574 life-years (LYs) and 0.500 quality-adjusted life-years (QALYs) vs BV and cost savings of $63,278. Drug acquisition costs were the biggest driver of incremental costs between strategies. Pembrolizumab had a 99.6% probability of being cost-effective compared with BV at a willingness-to-pay threshold of $20,000/QALY and dominated BV in all scenarios tested. LIMITATIONS: The analysis was subject to potential bias due to the use of a naive indirect treatment comparison and, given the current immaturity of OS in KEYNOTE-087, PPS was assumed equivalent across both treatments. CONCLUSION: Pembrolizumab is a cost-effective alternative to BV for patients with relapsed/refractory cHL after ASCT. PMID- 30303023 TI - Can Better Emotion Regulation Protect Against Interpersonal Violence in Homeless Youth Social Networks? AB - Homeless youth experience all types of violence at higher rates than their housed counterparts. This is typically the result of many contributing factors including childhood experiences of trauma, subsistence survival strategies, and exposure to perpetrators while living on the streets. Reducing violence in the lives of homeless youth is imperative and can contribute to a young person's ability to safely and successfully exit the streets and lead a long and productive life in society. However, developing public health and social interventions to reduce violence in adolescent and young adult populations is difficult due to the complex interplay of extrinsic and intrinsic drivers of this phenomenon. Los Angeles area homeless youth ( N = 366) were asked questions regarding recent violence experiences, emotion regulation, and their social network. Multivariable logistic regressions tested the overall effect of emotion regulation on violence, controlling for age, gender, race, sexual identity, experience of childhood abuse, and data collection site. In this sample, 56% of youth endorsed fighting in the previous year, and those who reported more difficulties with emotion regulation were significantly more likely to fight. In addition, youth who scored below the mean on difficulties with regulation and belonged to networks characterized by low-difficulty peers were 60% less likely to report fighting. Emotion regulation skills represent a malleable target for intervention that may contribute to reduced propensity for violence in this population. Implications for network-based interventions to improve individual emotion regulation and reduce overall violence among homeless youth and other at-risk populations are discussed. PMID- 30303021 TI - Botanical Formula LCS101: A Multi-Targeted Approach to Cancer Care. AB - BACKGROUND AND PURPOSE: LCS101 is a botanical formula extracted from 14 botanical components. While conventional oncology focuses on targeted medicine, research on LCS101 adopts a multi-targeted approach, examining its preclinical (in vitro, in vivo, and ex vivo) and clinical (randomized controlled trial, pragmatic) effects. This includes examining the formula's impact on the immune system, selective anticancer effects, and improved chemotherapy-related symptoms and quality of life. Effects on the Immune System: In murine splenic cell cultures, LCS101 significantly increased T-cell proliferation and macrophage tumor necrosis factor alpha production. Blood samples from healthy volunteers exposed to LCS101 showed a dose-dependent increase in natural killer cell activity; and a randomized controlled trial showed significantly lower rates of leucopenia/neutropenia and anemia in patients with breast cancer undergoing chemotherapy. Selective Anticancer Effects: In vitro LCS101 demonstrated selective growth inhibition (on XTT viability assay) in human breast and prostate cancer cell lines, without any harmful effects on normal human epithelial cells. The anticancer effects were attributed to reactive oxygen species activity. Cytotoxic effects of doxorubicin and 5-fluorouracil on breast cancer cell lines were significantly increased following exposure to LCS101, with a protective effect in normal cells. Symptom Relief and Quality of Life: Clinical research shows that patients taking LCS101 during chemotherapy are less likely to report symptoms such as fatigue, pain, nausea and vomiting. CONCLUSION: LCS101 exhibits multi-targeted effects, with significant implications for cancer care. Further research is needed to better understand the impact of these findings. PMID- 30303024 TI - BMI Trajectories in Adulthood: The Intersection of Skin Color, Gender, and Age among African Americans. AB - This study addresses three research questions critical to understanding if and how skin color shapes health among African Americans: (1) Does skin color predict trajectories of body mass index (BMI) among African Americans across ages 32 to 55? (2) To what extent is this relationship contingent on gender? (3) Do sociodemographic, psychosocial, and behavioral factors explain the skin color-BMI relationship? Using data from the Coronary Artery Risk Development in Young Adults Study and growth curve models, results indicate that dark-skinned women have the highest BMI across adulthood compared to all other skin color-gender groups. BMI differences between dark- and lighter-skinned women remain stable from ages 32 to 55. Among men, a BMI disadvantage emerges and widens between light- and dark-skinned men and their medium-skinned counterparts. Observed sociodemographic characteristics, stressors, and health behaviors do not explain these associations. Overall, findings suggest that skin color- and gender specific experiences likely play an important role in generating BMI inequality.

AB - This article describes the experience and impact of domestic violence on adolescents using qualitative methodology. It explores the meanings that adolescents give to their experiences and how this may relate to the impact of those experiences. Five adolescents who were receiving interventions within child and adolescent mental health services were interviewed about their experiences of domestic violence and the interviews were analyzed using interpretative phenomenological analysis (IPA). The results suggest that adolescents had a range of thoughts and feelings connected to their experiences, and that the impact of the domestic violence may be related to the different meanings that the adolescents gave to their experiences and how they made sense of those experiences. The results are explored using theories such as Grych and Fincham's Cognitive-Contextual Model; Watkin's elaborated Control Theory; and the work on posttraumatic growth. Research and clinical implications are discussed in the light of the results. PMID- 30303026 TI - The Contingent Effect of Guardianship on Victimization: An Examination of People With and Without Mental Health Problems. AB - Mixed effects of guardianship on victimization have been found in the literature. It is possible that these divergent findings have emerged because research has not recognized how the need for guardianship may shape the results. That is, individuals who are not suitable targets (i.e., individuals without mental health problems-those who are not perceived as vulnerable or incapable of defending themselves) do not need guardianship, resulting in null findings for the protective effects of guardianship on victimization. We examine the possibility that mental health problems and guardianship interact to produce victimization in the Life Opportunities Survey, a nationally representative survey of individuals in the United Kingdom ( N = 27,516). Logistic regression analyses support our hypothesis that the effects of guardianship on victimization, which is measured as violence or the threat of violence against an individual, are contingent on the presence of mental health problems (i.e., any emotional or psychological health condition). The risk of victimization for those with mental health problems who had guardianship was substantially lower than for those with mental health problems who lacked guardianship (11.5% vs. 17%, respectively). We discuss this finding in light of routine activities theory and crime prevention for people with mental health problems.

AB - We performed pathological and molecular virological investigation of three outbreaks of highly pathogenic avian influenza (HPAI) in a quail farm and two duck farms of Mymensingh and Netrokona districts of Bangladesh in 2011. HPAI viruses of subtype H5N1 were detected from all three outbreaks and phylogenetic analysis of HA gene sequence placed the viruses into clade 2.3.2.1. The outbreak in the quail farm was characterized by acute death with 100% mortality within two days. Marked haemorrhages and congestion with necrotic and inflammatory lesions in the respiratory tract, liver, pancreas and kidneys were the major gross and histopathological lesions. In the case of ducks, nervous signs were the remarkable clinical manifestations and the mortality was around 10%. No significant gross lesions were observed at necropsy. Non-purulent encephalitis with gliosis and neuronal degeneration was observed on histopathological examination. By immunohistochemistry, viral antigen could be detected in different organs of both quails and ducks. This study records varying clinical and pathological manifestations of HPAI in ducks and quails following natural infection with the same strain of the virus. RESEARCH HIGHLIGHTS HPAIV of clade 2.3.2.1 was detected from clinical outbreaks in quails and ducks Sudden death with severe haemorrhages in various organs was found in quails Pronounced nervous signs with non-purulent encephalitis were observed in ducks Viral antigen could be localized in different organs by immunohistochemistry.

AB - Periostin is an extracellular matrix protein from the fasciclin family that guides cellular trafficking and extracellular matrix organization. Periostin stimulates mature cardiomyocytes to reenter the cell cycle. The molecular mechanism behind such stimulation remains to be explored. A DNA microarray technology constituting 30,429 gene-level probe sets was utilized to investigate effects of recombinant murine periostin peptide on the gene expression pattern in a rat model of isoproterenol (ISO)-induced myocardial injury. The experiment was performed on 84 adult male Sprague-Dawley rats in four groups ( n = 21): (1) control group, (2) only periostin applied group, (3) ISO cardiotoxicity group, and (4) ISO + periostin group. The experiment was continued for 28 days, and rats were killed on days 1, 7, and 28 ( n = 7). Microarray analyses revealed that periostin significantly altered the expression of at least +/-2-fold of 2474 genes in the ISO + periostin group compared to the ISO cardiotoxicity group of which 521 genes altered out of 30,429 gene-level probe sets. Ingenuity pathway analysis indicated that multiple pathway networks were affected by periostin, with predominant changes occurring in the expression of genes involved in oxidative phosphorylation, oxidative stress, fatty acid metabolism, and TNF-alpha NF-kappaB signaling pathways. These findings indicate that periostin alters gene expression profile in the ISO-induced myocardial injury and modulates local myocardial inflammation, possibly mitigating inflammation through TNF-alpha NF kappaB signaling pathway along with a decreased Casp7 activity and apoptotic cell death. PMID- 30303031 TI - Public Stranger Violence-What Makes You Vulnerable?A Comparison of Perspectives From Young Adults and Industry Experts. AB - The purpose of this study was to determine the situational and individual factors that influence vulnerability to public stranger violence (PSV) from the perspective of young adults and industry professionals. In total, 25 young adults aged between 18 and 29 years formed one sample and participated in one of four focus groups. The second sample consisted of 10 industry professionals with backgrounds in policing, corrections, and forensic psychology. Each professional participated in an individual semistructured interview. Both samples were asked questions regarding vulnerability and safety in public, where responses were analyzed using a thematic analysis. Multiple themes were identified and categorized into situational and individual factors associated with victimization. Situational factors referred to aspects of the environment that may influence vulnerability to PSV and included visibility, location, and level of support for potential victims. Individual factors referred to aspects about the person that may influence vulnerability to PSV and included unpredictability, ease of target, stereotypes, in-groups versus out-groups, distractions, and personality traits. Although both samples identified similar situational factors, young adults were found to be either unaware of individual factors identified by industry professionals as influencing vulnerability or at least misunderstood some of these factors. This is problematic as young adults may be basing their public behaviors on misinformation that may in fact increase, rather than decrease, vulnerability to PSV. The findings from this study have implications for the design of personal safety programs as well as community-based interventions to reduce vulnerability, the prevalence of PSV, and the negative outcomes associated with PSV, including anxiety and fear of crime.

AB - The medial prefrontal cortex is a key area for the regulation of pain and emotion. However, the functional involvement of the medial prefrontal cortex for visceral nociception, at the neuronal or synaptic level, is obscure yet. In the present study, the properties of excitatory and inhibitory synaptic transmission within the layer II/III of rat medial prefrontal cortex after chronic myocardial infarction were studied. It is found that the excitation-inhibition ratio of the medial prefrontal cortex was greatly changed, with enhanced excitation and decreased inhibition inputs to the pyramidal cells of the medial prefrontal cortex, which largely due to decreased spike firing in gamma-aminobutyric acid ergic neurons. Behaviorally, inhibition of gamma-aminobutyric acid-ergic synaptic transmission alleviated the visceral pain and anxiety. It is thus for the first time showing that the excitation-inhibition ratio is increased in the medial prefrontal cortex after chronic myocardial infarction, which may come from the reduced intrinsic activity of gamma-aminobutyric acid-ergic neurons and is important for regulating the angina pectoris and anxiety induced by chronic myocardial infarction.

AB - CONTEXT: Plants of the genus Echinacea (Asteraceae) are among the most popular herbal supplements on the market today. Recent studies indicate there are potential new applications and emerging markets for this natural health product (NHP). OBJECTIVE: This review aims to synthesize recent developments in Echinacea biotechnology and to identify promising applications for these advances in the industry. METHODS: A comprehensive survey of peer-reviewed publications was carried out, focusing on Echinacea biotechnology and impacts on phytochemistry. This article primarily covers research findings since 2007 and builds on earlier reviews on the biotechnology of Echinacea. RESULTS: Bioreactors, genetic engineering and controlled biotic or abiotic elicitation have the potential to significantly improve the yield, consistency and overall quality of Echinacea products. Using these technologies, a variety of new applications for Echinacea can be realized, such as the use of seed oil and antimicrobial and immune boosting feed additives for livestock. CONCLUSIONS: New applications can take advantage of the well-established popularity of Echinacea as a NHP. Echinacea presents a myriad of potential health benefits, including anti-inflammatory, anxiolytic and antibiotic activities that have yet to be fully translated into new applications. The distinct chemistry and bioactivity of different Echinacea species and organs, moreover, can lead to interesting and diverse commercial opportunities. PMID- 30303035 TI - "Why Did She Talk to Him Again?" The Effects of the Justice Motive, Relationship Type, and Degree of Postassault Contact on Perceptions of Sexual Assault. AB - Victim blaming attitudes are prevalent within the criminal justice system where survivor behavior before, during, and following an assault is heavily scrutinized. Although dispositional characteristics (e.g., strength of one's justice motive) and characteristics of the assault (e.g., the type of relationship between a survivor and an offender) have been found to predict the degree of victim blaming, the effects of these variables on sexual assault myth endorsement are unclear. In addition, a variable that has not been examined in past literature is the degree of contact maintained between a survivor and offender after the assault. The purpose of the current study was to examine the extent to which the justice motive (strong vs. weak), the relationship between a fictional survivor and an offender (strangers vs. intimate partners), and contact between a survivor and offender postassault (contact vs. no contact) influenced endorsement of sexual assault myths. Undergraduate students read a vignette depicting a fictional sexual assault that varied with respect to the relationship and the amount of postassault contact between the survivor and offender and completed measures of the strength of their justice motive and their endorsement of sexual assault myths. Results indicated that participants ( N = 419) who held a strong justice motive showed higher endorsement of sexual assault myths. Participants were also more likely to endorse sexual assault myths when there was postoffense contact between the survivor and offender. The implications of these findings and their relevance to the criminal justice system are discussed, including the need for further research into the creation of survivor-oriented education and training capable of counteracting bias toward survivors of sexual violence and producing sustained attitudinal changes. PMID- 30303036 TI - Recommendations for cognitive screening and management in multiple sclerosis care. AB - PURPOSE:: To promote understanding of cognitive impairment in multiple sclerosis (MS), recommend optimal screening, monitoring, and treatment strategies, and address barriers to optimal management. METHODS:: The National MS Society ("Society") convened experts in cognitive dysfunction (clinicians, researchers, and lay people with MS) to review the published literature, reach consensus on optimal strategies for screening, monitoring, and treating cognitive changes, and propose strategies to address barriers to optimal care. RECOMMENDATIONS:: Based on current evidence, the Society makes the following recommendations, endorsed by the Consortium of Multiple Sclerosis Centers and the International Multiple Sclerosis Cognition Society: Increased professional and patient awareness/education about the prevalence, impact, and appropriate management of cognitive symptoms. For adults and children (8+ years of age) with clinical or magnetic resonance imaging (MRI) evidence of neurologic damage consistent with MS: As a minimum, early baseline screening with the Symbol Digit Modalities Test (SDMT) or similarly validated test, when the patient is clinically stable; Annual re-assessment with the same instrument, or more often as needed to (1) detect acute disease activity; (2) assess for treatment effects (e.g. starting/changing a disease-modifying therapy) or for relapse recovery; (3) evaluate progression of cognitive impairment; and/or (4) screen for new-onset cognitive problems. For adults (18+ years): more comprehensive assessment for anyone who tests positive on initial cognitive screening or demonstrates significant cognitive decline, especially if there are concerns about comorbidities or the individual is applying for disability due to cognitive impairment. For children (<18 years): neuropsychological evaluation for any unexplained change in school functioning (academic or behavioral). Remedial interventions/accommodations for adults and children to improve functioning at home, work, or school. PMID- 30303037 TI - Age is a critical determinant in recovery from multiple sclerosis relapses. AB - OBJECTIVE: To evaluate the impact of age on recovery from multiple sclerosis relapses. BACKGROUND: Increasing disability in multiple sclerosis is a consequence of progressive disease and incomplete relapse recovery. METHODS: The first and last-ever relapse data (357 relapses in 193 patients) from the Olmsted County population-based multiple sclerosis cohort were systematically reviewed for age, fulminance, location (optic nerve, brainstem/cerebellar, spinal cord), peak deficit, and maximum recovery. Three different relapse-outcome measures were studied both as paired analyses and as an overall group effect: change from peak deficit to maximum recovery in raw functional system score related to the relapse (DeltaFSS), a previously published FSS-based relapse-impact model, and change from peak deficit to maximum recovery in Extended Disability Status Scale (DeltaEDSS) score. RESULTS: Older age was linearly associated with worse recovery in the DeltaFSS outcome ( p = 0.002), DeltaEDSS outcome ( p < 0.001), and the FSS based relapse-impact model ( p < 0.001). A multivariate analysis of DeltaFSS outcome linked poor recovery to older age ( p = 0.015), relapse location (transverse myelitis or brainstem/cerebellar syndrome; p < 0.001), and relapse fulminance ( p = 0.004). CONCLUSION: Multiple sclerosis-relapse recovery declines in a linear fashion with increased age, which should be considered when making treatment decisions. PMID- 30303039 TI - Precarious work and the risk of receiving a disability pension. AB - AIMS: Precarious employment is an emerging determinant of occupational health, but its association with work-related disability remains little understood. We operationalised precarious work as a multidimensional construct and examined how the accumulation of precarious job features predicts the incidence of receiving a disability pension (DP). METHODS: The study comprised 13,228 employees aged 20-54 who had been interviewed for the Finnish Quality of Work Life Surveys in 1984, 1990, 1997, or 2003. We measured precarious work with five variables that reflect both subjective and objective job insecurity: the threat of dismissal/unemployment; poor employability; low earnings; previous unemployment; and temporary contract. An eight-year follow-up was merged with the pooled cross sectional data, and Cox proportional hazard ratios (HR) for receiving a DP were compared between the insecurity measures, controlling for sociodemographic covariates, job characteristics and health at the baseline with a step-wise procedure. RESULTS: Precarious employees had an elevated risk of receiving a DP (all covariates adjusted for). The risk of receiving a DP was associated with subjective job insecurity, with the strongest indicator being poor employability. The association between the threat of unemployment and receiving a DP was weak before controlling for health. Among objective insecurity measures, low earnings and earlier unemployment were weakly connected to receiving a DP before controlling for sociodemographic covariates, job characteristics and health. CONCLUSIONS: We recommend the evaluation of several precarious job features in future studies. The risk of receiving a DP could potentially be offset by improving individuals' employability. PMID- 30303038 TI - Investigating the Effects of Tactile Masking and Surface Texture on the Velvet Hand Illusion. AB - When we hold thin metallic bars between the palms of our hands and rub the palms against each other, the feeling of touching smooth velvet occurs. Previous studies have shown that tactile motion and pressure on the palms are important for this velvet hand illusion. Interestingly, when we experience this illusion, we cannot feel the texture of our palms as we usually do. In the present study, we investigated the possibility that tactile masking contributes to the occurrence of the velvet hand illusion. We measured vibrotactile detection performance on the palms of the hands during the occurrence of the velvet hand illusion. The detection performance was worse when the illusion occurred than when it did not. Moreover, the degradation of the detection performance correlated positively with the subjective magnitude of the illusion. We also examined whether additional surface texture could affect the occurrence of the illusion and found that the illusion became weaker as the roughness of the surface increased. These findings suggest that tactile motion and pressure information delivered by the bars of smooth surface mask tactile sensations on the palms of the hands, resulting in an illusory smooth, frictionless feeling on the palms. PMID- 30303040 TI - Electrochemically generated bimetallic reductive mediator Cu1+[Ni2+(CN)4]1- for the degradation of CF4 to ethanol by electro-scrubbing. AB - Remediation of electronic gas CF4 using commercially available technologies results in another kind of greenhouse gas and corrosive side products. This investigation aimed to develop CF4 removal at room temperature with formation of useful product by attempting an electrogenerated Cu1+[Ni2+(CN)4]1- mediator. The initial electrolysis of the bimetallic complex at the anodized Ti cathode demonstrated Cu1+[Ni2+(CN)4]1- formation, which was confirmed by additional electron spin resonance results. The degradation of CF4 followed mediated electrochemical reduction by electrogenerated Cu1+[Ni2+(CN)4]1-. The removal efficiency of CF4 of 95% was achieved by this electroscrubbing process at room temperature. The spectral results of online and offline Fourier transform infrared analyzer, either in gas or in solution phase, demonstrated that the product formed during the removal of CF4 by electrogenerated Cu1+[Ni2+(CN)4]1- by electroscrubbing was ethanol (CH3CH2OH), with a small amount of trifluoroethane (CF3CH3) intermediate. PMID- 30303041 TI - Relationship between genetic polymorphism of MTHFR C677T and lower extremities deep venous thrombosis. AB - OBJECTIVE: To investigate the association between the polymorphism of methylenetetrahydrofolate reductase (MTHFR) gene and the formation of lower extremities deep venous thrombosis, and to evaluate the etiology of deep venous thrombosis. METHODS: Polymorphisms of the 677th site C/T in MTHFR gene for 101 patients with lower extremities deep venous thrombosis (DVT group) and 120 healthy subjects (control group) were detected by polymerase chain reaction with sequence-specific primers. Genotype and allelic frequencies were compared between the two groups. RESULTS: Genotype frequencies of CC, CT and TT in MTHFR C677 T were 41.58, 25.74 and 32.67% in DVT group, and 58.33, 23.33 and 18.33% in control group, respectively. There was a significant difference in TT genotype frequency between the two groups (P <0.05). CONCLUSION: The frequency of MTHFR 677TT genotype may be correlated with the morbility of DVT. PMID- 30303042 TI - Workplace Heat Exposure Management in Indian Construction Workers Using Cooling Garment. AB - Construction workers are at high risk of heat-related illnesses during summer months in India. The personal cooling garment (PCG) is a microclimate assistive device that provides protection from heat stress. The applicability and efficacy of wearing PCG for the physiological and subjective responses were tested on 29 healthy construction workers at actual field worksites. During the test, the climatic conditions were 103.64 +/- 38.3 degrees F dry bulb temperature, 41.2 +/- 13.4% relative humidity, and wet bulb globe temperature 91.43 +/- 39.92 degrees F. Mean weighted skin temperature was significantly lowered by 38.66 +/- 33.98 degrees F when wearing PCG as compared with wearing habitual clothing (HC), 32.36 +/- 33.44 degrees F ( p < .05). Mean sweat loss was also significantly lower when wearing PCG: 0.365 +/- 0.257 kg as compared with wearing HC: 0.658 +/- 0.342 kg ( p < .05). Heart rate, along with back and chest skin temperatures were significantly reduced with wearing PCG. The present study suggests that PCG provides an affordable way of alleviating the discomfort and physiological strain caused by environmental heat exposure. PMID- 30303043 TI - Safety, long-term outcomes and predictors of recurrence following a single catheter ablation procedure for atrial fibrillation. AB - BACKGROUND: Data regarding long-term outcomes of atrial fibrillation (AF) catheter ablation are limited. This study evaluated the safety, long-term efficacy and predictors of recurrence after a single left atrial ablation procedure in patients with paroxysmal (PAF) and non-paroxysmal AF (NPAF). METHODS: Data from 520 patients (354 males, mean age 57.08 +/- 11.33 years) with PAF (n = 356, 68.5%) or NPAF (n = 164, 31.5%) who underwent a single radiofrequency ablation procedure were analysed. Across the NPAF group, there were 143 (27.5%) patients with persistent AF and 21 (4%) with long-standing persistent AF. The mean follow-up period was 39.05 +/- 20.83 months (range 19-60 months). RESULTS: Arrhythmia recurrence was observed in 102/356 (28.7%) of PAF patients and in 63/164 (38.4%) of NPAF patients. In patient with PAF, sinus rhythm maintenance was observed in 76.9%, 73% and 71.3% of patients at 1, 2 and 5 years of follow-up, respectively. In patients with NPAF, sinus rhythm was maintained in 68.7%, 63.4% and 61.6% of patients at 1, 2 and 5 years of follow up, respectively. Independent predictors of AF recurrence were left atrial diameter (OR 1.15, 95% CI 1.10-1.21, p < 0.01) as well as early arrhythmia recurrence during the blanking period of 3 months after the procedure (OR 8.13, 95% CI 5.10-12.82, p < 0.01). Major complications were observed in 11 patients (2.1%). CONCLUSIONS: Long-term arrhythmia-free survival rates remain high among PAF and NPAF patients after a single catheter ablation procedure. Left atrial diameter and early arrhythmia recurrence were independent predictors of late arrhythmia recurrence in both PAF and NPAF patients.

PMID- 30303044 TI - Inclusion of intimate partner violence-related content within undergraduate health care professional curriculum: mixed methods study of academics' attitudes and beliefs. AB - BACKGROUND: Undergraduate preparation is important in ensuring health care professionals are prepared to identify and respond to intimate partner violence (IPV). Previous studies confirm this education is highly variable and IPV-related content remains marginalised in undergraduate nursing, midwifery and paramedicine curricula. AIM: To investigate frontline academics' attitudes and beliefs in relation to the inclusion of IPV-related content in the aforementioned degrees. DESIGN: A large multi-phase mixed methods Australian case study of Australian undergraduate nursing, midwifery and paramedicine degrees. In this paper, components of the survey and interviews from this study will be reported on. METHODS: Quantitative comparative analysis of a 51-item on-line survey and qualitative thematic analysis of guided conversational interviews. RESULTS: Across Australian universities IPV remains poorly embedded in nursing, midwifery and paramedicine programmes. Academics report a range of barriers to such inclusion, including an already overcrowded curriculum, a lack of confident and competent academics to teach this content area and a lack of support for this content inclusion. One factor statistically significant in its association with non-inclusion of IPV-related content was academic attitudes of professional role resistance. Gender was also identified as a significant factor associated with non-inclusion and resistant professional attitudes. Qualitative interviews revealed that only six of the 18 participants identified IPV-related care as within their scope of practice, with professional role resistance a common theme identified. CONCLUSION: Though professional organisation and policy makers now advocate for the inclusion of IPV-related content in the undergraduate preparation of nurses and midwives, work remains to address gendered and resistant attitudes amongst academics.

AB - : ABSTRACTIntroduction:The relationship between Alzheimer's Disease (AD) and alcohol addiction is poorly characterized. Arrests for driving under the influence (DUI) can serve as a proxy for alcohol addiction. Therefore, the potential association between DUI and AD could be helpful in understanding the relationship between alcohol abuse and AD. MATERIALS AND METHODS: A retrospective, population-based cohort study using state health and law enforcement data was performed. The study cross-referenced 141,281 South Carolina Alzheimer's Disease Registry cases with state law enforcement data. RESULTS: Of the 2,882 registry cases (1.4%) found to have a history of at least one DUI arrest, cases were predominantly White (58.7%) and male (77.4%). Results showed a correlation coefficient of 0.7 (p < 0.0001) between the age of first DUI arrest and the age of AD diagnosis. A dose-response relationship between the number of DUIs and age of AD onset was found to exist, where those with a history of DUI arrest were diagnosed an average of 9.1 years earlier, with a further 1.8 years earlier age at diagnosis in those with two or more arrests for DUI. A history of DUI arrest was also found to be negatively associated with survival after diagnosis, with a 10% decreased life expectancy in those with a DUI arrest history. CONCLUSIONS: Driving under the influence, a potential indicator of alcohol addiction, is associated with an earlier onset of AD registry diagnosis and shortened survival after diagnosis. This study contributes to the growing body of evidence suggesting that some cases of AD are alcohol related and, possibly, postponable or preventable. PMID- 30303051 TI - Evaluating Mild Cognitive Impairment in Essential Tremor: How Many and Which Neuropsychological Tests? AB - OBJECTIVES: Essential tremor (ET) confers an increased risk for developing both amnestic and non-amnestic mild cognitive impairment (MCI). Yet, the optimal measures for detecting mild cognitive changes in individuals with this movement disorder have not been established. We sought to identify the cognitive domains and specific motor-free neuropsychological tests that are most sensitive to mild deficits in cognition as defined by a Clinical Dementia Rating (CDR) of 0.5, which is generally associated with a clinical diagnosis of MCI. METHODS: A total of 196 ET subjects enrolled in a prospective, longitudinal, clinical-pathological study underwent an extensive motor-free neuropsychological test battery and were assigned a CDR score. Logistic regression analyses were performed to identify the neuropsychological tests which best identified individuals with CDR of 0.5 (mild deficits in cognition) versus 0 (normal cognition). RESULTS: In regression models, we identified five tests in the domains of Memory and Executive Function which best discriminated subjects with CDR of 0.5 versus 0 (86.9% model classification accuracy). These tests were the California Verbal Learning Test II Total Recall, Logical Memory II, Verbal-Paired Associates I, Category Switching Fluency, and Color-Word Inhibition. CONCLUSIONS: Mild cognitive difficulty among ET subjects is best predicted by combined performance on five measures of memory and executive function. These results inform the nature of cognitive dysfunction in ET and the creation of a brief cognitive battery to assess patients with ET for cognitively driven dysfunction in life that could indicate the presence of MCI.

AB - Pulmonary artery sling is a congenital cardiovascular disease and is usually accompanied by tracheobronchial stenosis. Generally, infants diagnosed with pulmonary artery sling should have surgery. However, the treatment of tracheobronchial stenosis is still controversial. Our team developed a customised, degradable, three-dimensional printed splint and successfully applied it in the treatment of pulmonary artery sling associated with severe bilateral bronchus stenosis. We suggested that three-dimensional printing may be a novel and effective way to treat tracheobronchial stenosis and other diseases in children. PMID- 30303053 TI - Description of Ore Particles from X-Ray Microtomography (XMT) Images, Supported by Scanning Electron Microscope (SEM)-Based Image Analysis. AB - In this paper, three-dimensional (3D) image data of ore particle systems is investigated. By combining X-ray microtomography with scanning electron microscope (SEM)-based image analysis, additional information about the mineralogical composition from certain planar sections can be gained. For the analysis of tomographic images of particle systems the extraction of single particles is essential. This is performed with a marker-based watershed algorithm and a post-processing step utilizing a neural network to reduce oversegmentation. The results are validated by comparing the 3D particle-wise segmentation empirically with 2D SEM images, which have been obtained with a different imaging process and segmentation algorithm. Finally, a stereological application is shown, in which planar SEM images are embedded into the tomographic 3D image. This allows the estimation of local X-ray attenuation coefficients, which are material-specific quantities, in the entire tomographic image. PMID- 30303054 TI - WWGD (What would Gwyneth do?).

PMID- 30303056 TI - Clinical, personality, and neurodevelopmental phenotypes in borderline personality disorder: a family study. AB - BACKGROUND: Borderline personality disorder (BPD) is characterized by a heterogeneous clinical phenotype that emerges from interactions among genetic, biological, neurodevelopmental, and psychosocial factors. In the present family study, we evaluated the familial aggregation of key clinical, personality, and neurodevelopmental phenotypes in probands with BPD (n = 103), first-degree biological relatives (n = 74; 43% without a history of psychiatric disorder), and non-psychiatric controls (n = 99). METHODS: Participants were assessed on DSM-IV psychiatric diagnoses, symptom dimensions of emotion dysregulation and impulsivity, 'big five' personality traits, and neurodevelopmental characteristics, as part of a larger family study on neurocognitive, biological, and genetic markers in BPD. RESULTS: The most common psychiatric diagnoses in probands and relatives were major depression, substance use disorders, post traumatic stress disorder, anxiety disorders, and avoidant personality disorder. There was evidence of familial aggregation for specific dimensions of impulsivity and emotion dysregulation, and the big five traits neuroticism and conscientiousness. Both probands and relatives reported an elevated neurodevelopmental history of attentional and behavioral difficulties. CONCLUSIONS: These results support the validity of negative affectivity- and impulse-spectrum phenotypes associated with BPD and its familial risk. Further research is needed to investigate the aggregation of neurocognitive, neural and genetic factors in families with BPD and their associations with core phenotypes underlying the disorder.

AB - At present, the number of people with tuberculosis in China is second only to India and ranks second in the world. Under such a severe case of tuberculosis in China, prevention and control of pulmonary tuberculosis are urgently needed. This study aimed to study the temporal and geographical relevance of the pathogenesis of pulmonary tuberculosis and the factors affecting the incidence of tuberculosis. Spatial autocorrelation model was used to study the spatial distribution characteristics of pulmonary tuberculosis from a quantitative level. The research results showed that the overall incidence of pulmonary tuberculosis (IPT) in China was low in the east, high in the west and had certain seasonal characteristics. We use Spatial Lag Model to explore influencing factors of pulmonary tuberculosis. It indicates that the IPT is high in areas with underdeveloped economics, poor social services and low average smoking ages. Additionally, the IPT is high in areas with high AIDS prevalence. Also, compared with Classical Regression Model and Spatial Error Model, our model has smaller values of Akaike information criterion and Schwarz criterion. Besides, our model has bigger values of coefficient of determination (R2) and log-likelihood (log L) than the other two models. Apart from that, it is more significant than Spatial Error Models in the spatial dependence test for the IPT. PMID- 30303058 TI - Integrative review: Persistent vocalizations among nursing home residents with dementia. AB - : ABSTRACTBackground:Nursing home (NH) residents with dementia commonly exhibit persistent vocalizations (PVs), otherwise known in the literature as disruptive or problematic vocalizations. Having a better understanding of PVs and the research completed to date on this phenomenon is important to guide further research and clinical practice in NHs. This integrative review examines the current literature on the phenomenon of PVs among NH residents with dementia. METHODS: We conducted a search in the PubMed, Scopus, Ovid Medline, and CINAHL databases for articles published in English. Articles were included if the focus was specifically on research involving vocal behaviors of older adults with dementia residing in NHs. RESULTS: Our literature search revealed eight research articles that met the inclusion criteria. These studies were published in 2011 or earlier and involved small sample sizes. Seven of these studies were descriptive and the eighth was a non-pharmacological intervention study for PVs exhibited by NH residents with dementia. These studies were vastly different in their labeling, definitions, and categorization of the PVs as well as methods of measuring PVs. CONCLUSION: The heterogeneity of the evidence limits the ability to make recommendations for practice. Given the paucity of research on this phenomenon; recommendations for additional research are given.

AB - Traditional antibiograms can guide empiric antibiotic therapy, but they may miss differences in resistance across patient subpopulations. In this retrospective descriptive study, we constructed and validated antibiograms using International Classification of Disease, Tenth Revision (ICD-10) codes and other discrete data elements to define a cohort of previously healthy children with urinary tract infections. Our results demonstrate increased antibiotic susceptibility. This methodology may be modified to create other syndrome-specific antibiograms. PMID- 30303059 TI - The characteristics of psychotic features in bipolar disorder. AB - BACKGROUND: In a large and comprehensively assessed sample of patients with bipolar disorder type I (BDI), we investigated the prevalence of psychotic features and their relationship with life course, demographic, clinical, and cognitive characteristics. We hypothesized that groups of psychotic symptoms (Schneiderian, mood incongruent, thought disorder, delusions, and hallucinations) have distinct relations to risk factors. METHODS: In a cross-sectional study of 1342 BDI patients, comprehensive demographical and clinical characteristics were assessed using the Structured Clinical Interview for DSM-IV (SCID-I) interview. In addition, levels of childhood maltreatment and intelligence quotient (IQ) were assessed. The relationships between these characteristics and psychotic symptoms were analyzed using multiple general linear models. RESULTS: A lifetime history of psychotic symptoms was present in 73.8% of BDI patients and included delusions in 68.9% of patients and hallucinations in 42.6%. Patients with psychotic symptoms showed a significant younger age of disease onset (beta = -0.09, t = 3.38, p = 0.001) and a higher number of hospitalizations for manic episodes (F11 338 = 56.53, p < 0.001). Total IQ was comparable between groups. Patients with hallucinations had significant higher levels of childhood maltreatment (beta = 0.09, t = 3.04, p = 0.002). CONCLUSIONS: In this large cohort of BDI patients, the vast majority of patients had experienced psychotic symptoms. Psychotic symptoms in BDI were associated with an earlier disease onset and more frequent hospitalizations particularly for manic episodes. The study emphasizes the strength of the relation between childhood maltreatment and hallucinations but did not identify distinct subgroups based on psychotic features and instead reported of a large heterogeneity of psychotic symptoms in BD. PMID- 30303061 TI - Dialectical behaviour therapy v. mentalisation-based therapy for borderline personality disorder. AB - BACKGROUND: Dialectical behaviour therapy (DBT) and mentalisation-based therapy (MBT) are both widely used evidence-based treatments for borderline personality disorder (BPD), yet a head-to-head comparison of outcomes has never been conducted. The present study therefore aimed to compare the clinical outcomes of DBT v. MBT in patients with BPD. METHODS: A non-randomised comparison of clinical outcomes in N = 90 patients with BPD receiving either DBT or MBT over a 12-month period. RESULTS: After adjusting for potentially confounding differences between participants, participants receiving DBT reported a significantly steeper decline over time in incidents of self-harm (adjusted IRR = 0.93, 95% CI 0.87-0.99, p = 0.02) and in emotional dysregulation (adjusted beta = -1.94, 95% CI -3.37 to 0.51, p < 0.01) than participants receiving MBT. Differences in treatment dropout and use of crisis services were no longer significant after adjusting for confounding, and there were no significant differences in BPD symptoms or interpersonal problems. CONCLUSIONS: Within this sample of people using specialist personality disorder treatment services, reductions in self-harm and improvements in emotional regulation at 12 months were greater amongst those receiving DBT than amongst those receiving MBT. Experimental studies assessing outcomes beyond 12 months are needed to examine whether these findings represent differences in the clinical effectiveness of these therapies.

PMID- 30303063 TI - Maternal antenatal mood and child development: an exploratory study of treatment effects on child outcomes up to 5 years. AB - Effective treatment of maternal antenatal depression may ameliorate adverse neurodevelopmental outcomes in offspring. We performed two follow-up rounds of children at age 2 and age 5 whose mothers had received either specialized cognitive-behavioural therapy or routine care for depression while pregnant. Of the original cohort of 54 women, renewed consent was given by 28 women for 2-year follow-up and by 24 women for 5-year follow-up. Child assessments at the 2-year follow-up included the Parenting Stress Index (PSI), Bayley Scales of Infant Development (BSID-III) and the Child Behaviour Checklist (CBCL). The 5-year follow-up included the Wechsler Preschool and Primary Scales of Intelligence (WPPSI-III) and again the CBCL. Treatment during pregnancy showed significant benefits for children's development at age 2, but not at age 5. At 2 years, intervention effects were found with lower scores on the PSI Total score, Parent Domain and Child domain (d=1.44, 1.47, 0.96 respectively). A non-significant trend favoured the intervention group on most subscales of the CBCL and the BSID III (most notably motor development: d =0.52). In contrast, at 5-year follow-up, no intervention effects were found. Also, irrespective of treatment allocation, higher depression or anxiety during pregnancy was associated with higher CBCL and lower WPPSI-III scores at 5 years. This is one of the first controlled studies to evaluate the long-term effect of antenatal depression treatment on infant neurodevelopmental outcomes, showing some benefit. Nevertheless, caution should be taken interpreting the results because of a small sample size, and larger studies are warranted. PMID- 30303064 TI - Written progress tests in postgraduate psychiatry. PMID- 30303065 TI - Depressive symptoms in relation to clinical symptom onset of mild cognitive impairment. AB - : ABSTRACTObjective:There is increasing evidence of an association between depressive symptoms and mild cognitive impairment (MCI) in cross-sectional studies, but the longitudinal association between depressive symptoms and risk of MCI onset is less clear. The authors investigated whether baseline symptom severity of depression was predictive of time to onset of symptoms of MCI. METHOD: These analyses included 300 participants from the BIOCARD study, a cohort of individuals who were cognitively normal at baseline (mean age = 57.4 years) and followed for up to 20 years (mean follow-up = 2.5 years). Depression symptom severity was measured using the Hamilton Depression Scale (HAM-D). The authors assessed the association between dichotomous and continuous HAM-D and time to onset of MCI within 7 years versus after 7 years from baseline (reflecting the mean time from baseline to onset of clinical symptoms in the cohort) using Cox regression models adjusted for gender, age, and education. RESULTS: At baseline, subjects had a mean HAM-D score of 2.2 (SD = 2.8). Higher baseline HAM-D scores were associated with an increased risk of progression from normal cognition to clinical symptom onset <= 7 years from baseline (p = 0.043), but not with progression > 7 years from baseline (p = 0.194). These findings remained significant after adjustment for baseline cognition. CONCLUSIONS: These results suggest that low levels of depressive symptoms may be predictive of clinical symptom onset within approximately 7 years among cognitively normal individuals and may be useful in identifying persons at risk for MCI due to Alzheimer's disease.

PMID- 30303066 TI - Adrb2 controls glucose homeostasis by developmental regulation of pancreatic islet vasculature. AB - A better understanding of processes controlling the development and function of pancreatic islets is critical for diabetes prevention and treatment. Here, we reveal a previously unappreciated function for pancreatic beta2-adrenergic receptors (Adrb2) in controlling glucose homeostasis by restricting islet vascular growth during development. Pancreas-specific deletion of Adrb2 results in glucose intolerance and impaired insulin secretion in mice, and unexpectedly, specifically in females. The metabolic phenotypes were recapitulated by Adrb2 deletion from neonatal, but not adult, beta-cells. Mechanistically, Adrb2 loss increases production of Vascular Endothelial Growth Factor-A (VEGF-A) in female neonatal beta-cells and results in hyper-vascularized islets during development, which in turn, disrupts insulin production and exocytosis. Neonatal correction of islet hyper-vascularization, via VEGF-A receptor blockade, fully rescues functional deficits in glucose homeostasis in adult mutant mice. These findings uncover a regulatory pathway that functions in a sex-specific manner to control glucose metabolism by restraining excessive vascular growth during islet development.

Clinically, it is classified as early-stage (medium-sized drusen and retinal pigmentary changes) to late-stage (neovascular and atrophic). Age-related macular degeneration is a multifactorial disorder, with dysregulation in the complement, lipid, angiogenic, inflammatory, and extracellular matrix pathways implicated in its pathogenesis. More than 50 genetic susceptibility loci have been identified, of which the most important are in the CFH and ARMS2 genes. The major non-genetic risk factors are smoking and low dietary intake of antioxidants (zinc and carotenoids). Progression from early-stage to late-stage disease can be slowed with high-dose zinc and antioxidant vitamin supplements. Intravitreal anti-vascular endothelial growth factor therapy (eg, ranibizumab, aflibercept, or bevacizumab) is highly effective at treating neovascular age related macular degeneration, and has markedly decreased the prevalence of visual impairment in populations worldwide. Currently, no proven therapies for atrophic disease are available, but several agents are being investigated in clinical trials. Future progress is likely to be from improved efforts in prevention and risk-factor modification, personalised medicine targeting specific pathways, newer anti-vascular endothelial growth factor agents or other agents, and regenerative therapies.

PMID- 30303108 TI - Molecular point-of-care testing for chlamydia and gonorrhoea in Indigenous Australians attending remote primary health services (TTANGO): a cluster randomised, controlled, crossover trial. AB - BACKGROUND: Timely diagnosis and treatment of sexually transmissible infections will prevent morbidity and onward transmission. We aimed to assess the efficacy of a point-of-care molecular test for Chlamydia trachomatis and Neisseria gonorrhoeae infections at the cluster level to improve infection management among Indigenous Australian communities with high prevalence of sexually transmissible infections. METHODS: In this cluster-randomised crossover study, we recruited primary health services in Western Australia, Far North Queensland, and South Australia that provide care to Indigenous people in regional or remote locations. The services were eligible if they did 150 or more tests for C trachomatis or N gonorrhoeae infection per year among individuals aged 16-29 years, and if C trachomatis or N gonorrhoeae positivity was 10% or higher. Services were randomly assigned (1:1) by use of a random-number generator, stratified by geographical region, to either standard care conditions with routine laboratory-based sexually transmissible infection testing for 12 months followed by 12 months of intervention with molecular point-of-care testing, or the reverse sequence. The primary outcome was the proportion of people (aged 16-29 years) found to have C trachomatis or N gonorrhoeae who had a positive result at retesting 3 weeks to 3 months after treatment, and a secondary outcome was treatment within 7 days, both in those aged 16-29 years and at the cluster level. We did these analyses using data from all participants who had a positive result at testing, by point-of-care of laboratory testing (ie, the intention-to-treat population). The trial is registered with Australian and New Zealand Clinical Trials Registry (ACTRN12613000808741). FINDINGS: Between June 1, 2013, and Feb 29, 2016, 12 health services were enrolled and randomly assigned to standard care followed by intervention (six) and the reverse sequence (six). After randomisation, one health service that was initially assigned to standard care was excluded because it no longer met the inclusion criteria. 455 individuals tested positive for C trachomatis or N gonorrhoeae infection in the intervention group, and 405 tested positive in the standard care group. In the intervention group, 12 (19%) of 63 individuals retested had a positive test result, compared with nine (13%) of 67 with positive retests in the standard care group (relative ratio [RR] 1.42, 95% CI 0.64-3.13; p=0.405), and 347 (76%) were treated within 7 days in the intervention group, compared with 191 (47%) in the standard care group (RR 1.66, 1.41-1.93; p<0.0001). INTERPRETATION: Retesting rates were too low to draw conclusions on the effect of the intervention on repeat infections. Further research will be needed to determine whether point-of-care tests have an effect on reinfection rates, and the sustainability of using this technology. However, our findings show that time to treatment of C trachomatis or N gonorrhoeae infections in primary care clinics in remote areas in Australia with a high prevalence of sexually transmissible infections could be substantially reduced by the use of molecular point-of-care tests.

PMID- 30303126 TI - Opportunities and priorities for breast surgical research. AB - The 2013 Breast Cancer Campaign gap analysis established breast cancer research priorities without a specific focus on surgical research or the role of surgeons on breast cancer research. This Review aims to identify opportunities and priorities for research in breast surgery to complement the 2013 gap analysis. To identify these goals, research-active breast surgeons met and identified areas for breast surgery research that mapped to the patient pathway. Areas included diagnosis, neoadjuvant treatment, surgery, adjuvant therapy, and attention to special groups (eg, those receiving risk-reducing surgery). Section leads were identified based on research interests, with invited input from experts in specific areas, supported by consultation with members of the Association of Breast Surgery and Independent Cancer Patients' Voice groups. The document was iteratively modified until participants were satisfied that key priorities for surgical research were clear. Key research gaps included issues surrounding overdiagnosis and treatment; optimising treatment options and their selection for neoadjuvant therapies and subsequent surgery; reducing rates of re-operations for breast-conserving surgery; generating evidence for clinical effectiveness and cost-effectiveness of breast reconstruction, and mechanisms for assessing novel interventions; establishing optimal axillary management, especially post neoadjuvant treatment; and defining and standardising indications for risk reducing surgery. We propose strategies for resolving these knowledge gaps. Surgeons are ideally placed for a central role in breast cancer research and should foster a culture of engagement and participation in research to benefit patients and health-care systems. Development of infrastructure and surgical research capacity, together with appropriate allocation of research funding, is needed to successfully address the key clinical and translational research gaps that are highlighted in this Review within the next two decades. PMID- 30303127 TI - Use of modern imaging methods to facilitate trials of metastasis-directed therapy for oligometastatic disease in prostate cancer: a consensus recommendation from the EORTC Imaging Group. AB - Oligometastatic disease represents a clinical and anatomical manifestation between localised and polymetastatic disease. In prostate cancer, as with other cancers, recognition of oligometastatic disease enables focal, metastasis directed therapies. These therapies potentially shorten or postpone the use of systemic treatment and can delay further metastatic progression, thus increasing overall survival. Metastasis-directed therapies require imaging methods that definitively recognise oligometastatic disease to validate their efficacy and reliably monitor response, particularly so that morbidity associated with inappropriately treating disease subsequently recognised as polymetastatic can be avoided. In this Review, we assess imaging methods used to identify metastatic prostate cancer at first diagnosis, at biochemical recurrence, or at the castration-resistant stage. Standard imaging methods recommended by guidelines have insufficient diagnostic accuracy for reliably diagnosing oligometastatic disease. Modern imaging methods that use PET-CT with tumour-specific radiotracers (choline or prostate-specific membrane antigen ligand), and increasingly whole body MRI with diffusion-weighted imaging, allow earlier and more precise identification of metastases. The European Organisation for Research and Treatment of Cancer (EORTC) Imaging Group suggests clinical algorithms to integrate modern imaging methods into the care pathway at the various stages of prostate cancer to identify oligometastatic disease. The EORTC proposes clinical trials that use modern imaging methods to evaluate the benefits of metastasis directed therapies. PMID- 30303128 TI - Advancing shared decision making for symptom monitoring in people living beyond cancer. AB - Wellbeing after successful cancer treatment depends on more than merely reducing the risk of disease recurrence. Cancer survival can be characterised by uncertainty, fear, and the interpretation of bodily sensations as potentially symptomatic of cancer recurrence. This fear can lead to over-vigilance about bodily sensations and precautionary visits to the doctor, both of which can increase the chance of early detection but can also increase anxiety and decrease quality of life. In this Personal View, we consider the medical, psychological, and ethical issues related to the practice of self-directed symptom monitoring after completion of cancer treatment, focusing on the role of doctor-patient communication. We ask how clinicians can account for the plurality of values that patients might have when it comes to deciding on how to manage and respond to experiences of post-cancer symptoms. We advocate a shared decision-making approach that incorporates the assessment of an individual's cancer recurrence risks as well as psychosocial considerations regarding fear of cancer recurrence and mental health. We aim to raise awareness of the potential quality-of-life implications of symptom-monitoring practices, emphasising the need for a balance between physical and psychological health in people living beyond cancer.

AB - OBJECTIVE: A primary control signal in brain-computer interfaces (BCIs) have been cortical signals related to movement. However, in cases where natural motor function remains, BCI control signals may interfere with other possibly simultaneous activity for useful ongoing movement. We sought to determine if the brain could learn to control both a BCI and concurrent overt movement execution in such cases. APPROACH: We designed experiments where BCI and overt movements must be used concurrently and in coordination to achieve a 2D centre out control. Power in the 70-90 Hz band of human electrocorticography (ECoG) signals, was used to generate BCI control commands for vertical movement of the cursor. These signals were deliberately recorded from the same human cortical site that produced the strongest movement related activity associated with the concurrent overt finger movements required for the horizontal movement of the cursor. MAIN RESULTS: We demonstrate that three subjects were able to perform the concurrent BCI task, controlling BCI and natural movements simultaneously and to a large extent independently. We conclude that the brain is capable of dissociating the original control signal dependency on movement, producing specific BCI control signals in the presence of motor related responses from the ongoing overt behaviour with which the BCI signal was initially correlated. SIGNIFICANCE: We demonstrate a novel human brain-computer interface (BCI) which can be used to control movement concurrently and in coordination with movements of the natural limbs. This demonstrates the dissociation of cortical activity from the behaviour with which it was originally associated despite the ongoing behaviour and shows the feasibility of achieving simultaneous BCI control of devices with natural movements. PMID- 30303133 TI - Expression of alpha-smooth muscle actin in benign and malignant salivary gland tumors: An immunohistochemical study. AB - Background and Objectives: Myoepithelial cells (ME) are known to contribute in the patterning of salivary gland neoplasms (SGN) and possess cytoplasmic smooth muscle actin (SMA) revealed by alpha SMA (alpha-SMA). The present study aimed to assess the expression of alpha-SMA in selected benign and malignant SGN (pleomorphic adenoma [PA], mucoepidermoid carcinoma (MEC), adenoid cystic carcinoma (ACC), and polymorphous low-grade adenocarcinoma (PLGA). Materials and Methods: The intensity and pattern of expression of alpha-SMA were studied in 25 cases of SGN's ACC (n = 7), MEC (n = 8), PA (n = 8), and PLGA (n = 2), and correlated with the histological patterns. Results: Maximum expression of alpha SMA in the epithelial compartment was seen in ACC, followed by PA, whereas MEC and PLGA showed completely negative staining. The connective tissue expression was mild in ACC and MEC. The myxoid stroma of PA with "melting" pattern was weakly positive for alpha-SMA. The stroma in PLGA showed complete negativity. In ACC, alpha-SMA-positive cells were lining the cribriform spaces, small islands, and dispersed within large islands. Small nests showed complete positivity for alpha-SMA. Interpretation and Conclusion: In ACC, alpha-SMA expression supports the involvement of ME in epithelial organization explaining the histological patterns seen. In PA, the expression correlates with the predominantly secretory nature of ME. The absence of epithelial positivity in MEC and PLGA suggest that ME has less role to play in their histogenesis. The weak stromal positivity observed in MEC and ACC may be attributed to the positive immunoreactivity of myofibroblasts playing a role in modulating the course of SGN's. PMID- 30303134 TI - C-cell hyperplasia in sporadic and familial medullary thyroid carcinoma. AB - Context: C-cell hyperplasia (CCH) is characterized by increased mass of C-cells and has been identified as a precursor condition for medullary thyroid carcinoma (MTC). Varying proportion of MTCs is associated with CCH in different studies. This could be due to the lack of uniformity of the definitions and techniques used to identify CCH in these studies. Aims: This study aims to study the occurrence, clinicopathological, and immunohistochemical features of CCH in MTC diagnosed during a 22-year period at a tertiary care center in North India and to review the available literature on CCH. Materials and Methods: Eighty-seven consecutive cases of MTC were included in the study. Histological evaluation for the presence of CCH and neoplastic CCH was performed. Confirmation of CCH was done by immunohistochemistry for calcitonin and chromogranin. The presence of neoplastic CCH was correlated with clinical factors and prognostic factors. Results: Of 87 cases of MTC included in the study, 71 (82%) patients were sporadic and 16 (18%) had familial MTC. Neoplastic CCH was seen in 12 (75%) familial and in 9 (13%) sporadic MTC. Patients with familial MTC were more frequently associated with neoplastic CCH than sporadic MTC (P < 0.001), were younger (P < 0.001), and had more often bilateral and multifocal tumors (P < 0.001). However, there was no significant difference in mean survival time and progression-free survival in patients with and without CCH. Conclusion: CCH, though more common in familial MTC, can also be seen in sporadic tumors. CCH is not associated with patient survival and disease progression. PMID- 30303136 TI - An autopsy based descriptive study of the spectrum of pulmonary lesions encountered in fetal deaths at a tertiary care center. AB - Background: : Fetal autopsy has been an indispensable tool in evaluating the cause of death. The most common cause for fetal deaths is associated with respiratory disorders accounting for around 60%. This study was undertaken to evaluate the gross and microscopic features of lungs in fetal autopsies and estimate the incidence of deaths attributable to pulmonary causes. Materials and Methods: : All fetuses received for autopsy at our institute were included in the study with prior consent. Gross and microscopic findings along with relevant clinical data were recorded. Results: A total of 426 autopsies were conducted from January 2011 to August 2016. Of those, 184 had abnormal pulmonary findings constituting 43.19%. Aspiration pneumonia was the most common finding with 67 cases (36.4%), followed by atelectasis 54 cases (29.3%), congenital cystic adenomatoid malformation in 13 cases (7.1%), lung hypoplasia 12 cases (6.5%), pulmonary hemorrhage 21 (11.4%), 15 cases (8.15%) of hyaline membrane disease, one case (0.5%) of heterotaxy, and one case of extralobar pulmonary sequestration (0.5%). Congenital malformations of lungs were seen in 27 (14.67%) cases and 38 cases (20.65%) had other associated anomalies. Conclusion: Pulmonary pathology is the most common finding in fetal deaths with aspiration pneumonitis being the most common avoidable cause. Accurate fetal autopsy along with clinical data are important in evaluating fetal deaths and can help in reduction of unexplained stillbirths. PMID- 30303135 TI - A prospective study of association of cancer stem cell marker aldehyde dehydrogenase 1 with clinicopathological profile in lung carcinoma patients. AB - Context: In India, lung carcinoma is the fifth-most common tumor and second-most common tumor in the males as per the Indian Council of Medical Research registry of 2002. It has been seen that ALDH1 expression in non-small cell lung cancer (NSCLC) and the presence of marker was linked to a more tumorigenic potential in the in vivo assessment and shorter disease-free survival in NSCLC patients with platinum treatment. Aims: Hence, our objective was to detect association of cancer stem cell (CSC) marker aldehyde dehydrogenase 1 (ALDH1) with clinicopathological profile in lung carcinoma patients. Settings and Design: This is a Pilot study. Subjects and Methods: It was a Pilot study where biopsies from 55 fresh previously untreated lung cancer patients visiting the Pulmonary Medicine Department of Era's Lucknow Medical College and Hospital Lucknow and King George's Medical University were taken for 18 months November 2014-April 2016, after taking proper informed consent from them. Paraffin blocks were taken and stained by hematoxylin and eosin (Sigma) to make the histopathological diagnosis and immunohistochemistry was done for detection of CSC marker ALDH1 (Daco). Statistical Analysis Used: The statistical analysis was done using Statistical Package for Social Sciences Version 15.0 Statistical Analysis Software. The values were represented in number (%) and mean +/- standard deviation. Results: Expression of stem cell marker ALDH1 with the staging of the tumor was observed in 62.5% of Stage I, 80% of Stage II, 94.1% of Stage III, and 100% of Stage IV cases. Statistically, there was a significant association between ALDH1expression and stage of disease (P < 0.001). Diagnostic efficacy of ALDH1 expression in the detection of any positive clinical stage, it was found to be 88.6% sensitive and 90.9% specific. Conclusions: Strong ALDH1 expression correlates with higher stage of lung carcinoma making it a prognostic marker needing in-depth study. PMID- 30303137 TI - Evaluation of CD30/CD4/CD8 in triple-negative invasive ductal carcinoma of breast in association with clinicopathological prognostic factors. AB - Background: Triple-negative breast cancer (TNBC) lacks the benefits of receptor targeted therapeutic strategies. The limitations in treatment options along with poor patients' outcome heighten the need for novel approaches. Due to recent concentration on the role of biomarkers in prognosis, treatment, and survival of various cancer subtypes, this study involves an investigation of CD4, CD8, and CD30 markers detected by immunohistochemistry in TNBCs and their association with clinicopathological and prognostic factors. Materials and Methods: Tissue samples of 85 hormone receptor- and human epidermal growth factor receptor-2-negative ductal breast carcinomas extracted from the archive of pathology department. Regarding CD4/CD8 ratio, the infiltrated T-lymphocytes were investigated. The tumoral tissue regions were also identified to be immunohistochemically assessed for the CD30 expression levels. Results: With an elevated CD4/CD8 ratio, a significant increase in lymph node involvement was observed (P < 0.05); in contrast, increased expression levels of CD8 were related to significant reduction of lymph node involvement. CD30 overexpression was found to be significantly associated with shortened overall survival (OS) and highly involvement of lymph nodes. Conclusion: Following the progression in stage and grade of tumor, CD4/CD8 ratio and CD30 expression levels are increased and are accompanied by adverse prognosis and poor OS, while CD8-enhanced expression carries a favorable prognostic impact as it improves OS status. Therefore, all these findings could be of interest in the field of target therapy. PMID- 30303138 TI - Prognostic indices predictive of short-term disease-free survival of breast carcinoma patients receiving primary surgical treatment in Sri Lanka. AB - Background: Breast carcinoma (BCa) is the commonest malignancy among women worldwide and in Sri Lanka. Several prognostic indices are described for BCa. Aims: To assess clinicopathological features and prognostic indices derived from routine clinical, histopathological and immunohistochemical (IHC) data, in a cohort of patients undergoing primary surgery for BCa and to determine their prognostic impact on short-term disease free survival. Setting and Design: : This is a bidirectional cohort study of 208 women undergoing primary surgery for BCa at the National Hospital of Sri Lanka, from 2012-2014, excluding post-neoadjuvant chemotherapy cases. Material and Methods: Clinical details, tumor size and nodal status were obtained from histopathology reports. Histopathology and estrogen/progesterone receptor and HER2 status were reviewed. Molecular subtype based on IHC was determined. Nodal ratio (number of positive nodes/total number retrieved) and Nottingham prognostic index were calculated. Follow up information was obtained by patient interviews and record review. Statistical Analysis: Data was analyzed by univariate and multivariate Cox regression using SPSS19.0. Results: Mean follow-up duration was 27.16 months (0.5-52 months, s = 9.35 months). 174 (82.9%) remained disease free with 19 (9%) deaths. Thirteen (6.2%) survived with metastasis and 4 (1.9%) with recurrences. On univariate Cox regression, tumor, nodal and TNM stages, nodal ratio and lymphovascular invasion (LVI) were predictive of disease free survival (DFS) (P = 0.001, P = 0.021, P = 0.022, P = 0.002, P = 0.018). On multivariate analysis TNM stage and LVI were predictive of DFS. Conclusion: TNM stage and LVI were the most important predictors of short-term disease free survival in this study population, confirming that early detection of BCa at a lower stage has a significant impact on short-term outcomes. PMID- 30303139 TI - Diagnostic utility of CD10 immunohistochemical staining on cellblock in differentiating hepatocellular carcinoma from secondary malignancies of liver. AB - Background: Differentiation of hepatocellular carcinoma (HCC) from metastatic malignancy in liver may be difficult at times on fine-needle aspiration cytology, especially in case of moderate-to-poorly differentiated tumors. The benefit of cell-block technique is the recognition of histologic pattern of diseases along with application of a wide variety of immunohistochemical (IHC) stains to differentiate hepatic malignancies. In this study, CD10 IHC staining was done on cellblocks prepared from aspirates of clinicoradiologically/cytologically suspected malignant liver neoplasms to differentiate HCC from malignancies metastasizing to liver. Objective: The objective of the study was to assess the diagnostic utility of CD10 IHC stain on cell-block preparation for differentiating primary from Secondary malignancies of liver. Materials and Methods: Formalin-fixed, paraffin-embedded cellblocks of 61 cases (25 cases of HCC and 36 cases of metastatic carcinoma) were prepared from a fine-needle aspirate of the suspected malignant liver neoplasm and immunostained using monoclonal antibody against CD10. Results: Twenty-two (88%) of 25 cases of HCC were positive for CD10 with a canalicular staining pattern. Two (8%) were positive for CD10 with membranous and one (4%) with cytoplasmic staining pattern. Conclusion: CD10 immunostaining on cellblock is useful in discriminating HCC and metastatic carcinoma of the liver with a diagnostic accuracy of 88.52%. PMID- 30303140 TI - Intracholecystic papillary-tubular neoplasm of gallbladder: A 5-year retrospective pathological study. AB - Background: Intracholecystic papillary-tubular neoplasm (ICPN) is a relatively new entity which includes neoplastic polyps, adenomas, and papillary neoplasms that are >=1.0 cm. This study is done to evaluate the pathological features of ICPN and to find out the factors associated with invasion. Materials and Methods: This is a 5-year retrospective study in a referral pathology center. A total of 19 cases of ICPN are found. The cases are analyzed for age and sex distribution, clinical suspicion, stages, histological architecture, differentiation, and grade of dysplasia. Descriptive statistics and test of significance by Chi-square and t test are used in the study. Results: ICPN comprises 23.5% of all gallbladder neoplasms. Two-thirds of the cases were suspected radiologically. Age range is 26 65 years with mean age of 50 years. They are 2.8 times more common in female. Approximately one-third of the cases show invasion. The most common histological pattern is papillary, followed by papillary-tubular and finally by tubular pattern. Pyloric and biliary are the most common differentiation pattern followed by oncocytic and intestinal pattern. About three-fourths of the cases are associated with high-grade dysplasia mostly diffuse high-grade dysplasia. Conclusion: We have found the younger age of presentation, less proportion of invasive tumors, fewer tumors with biliary phenotypes, and fewer tumors with high grade dysplasia as compared to previous studies. Factors significantly associated with invasion are grade and extent of dysplasia particularly diffuse high-grade dysplasia.

MSI status has important prognostic and therapeutic implications. The prevalence of MSI in Indian CRC patients is unknown. We aimed to determine the prevalence by studying 231 consecutive unselected cases of CRC. Methods: Tissue microarrays using duplicate cores per case for 141 cases, and whole tissue sections for 90 cases, were used. Immunohistochemistry with four mismatch repair (MMR) markers - MLH1, MSH2, MSH6, and PMS2 was performed. Molecular analysis for MSI status was performed in 18 randomly selected cases. Correlation with various clinical and histopathological features was done using univariate and multivariate analysis. Results: Loss of MMR immunohistochemical (IHC) was seen in 53/231 cases, i.e. 22.94% (95% confidence interval 17.52%-28.36%). MLH1-PMS2 dual loss comprised 13.9%, MSH2 MSH6 7.4%, and isolated PMS2 loss in 1.73% of cases. Univariate analysis showed significant association with age (<60 years), right-sided tumor location, histologic type, high grade, the presence of severe intratumoral lymphocytic (ITL) and peri-tumoral lymphocytic response, and N0 nodal stage. On multivariate analysis, independent variables were age < 60 years, right-sided location, and severe ITL. Molecular testing for MSI corroborated with the IHC results. Conclusion: The study results show a slightly higher prevalence of MSI-H phenotype, compared to Western literature, stressing the need for more widespread testing for better clinical management and identification of possible hereditary colon cancer syndrome.

AB - Background: Transurethral resection of tumor is the main treatment of non-muscle invasive urothelial carcinoma, but it is associated with high rate of recurrence and/or progression and this arouses the need for adjuvant therapy. Topoisomerase II (Top II), KI-67, and P53 are proliferation and cell cycle regulation markers that may predict tumor response to therapy. Aim: This study aimed to assess Top II, KI-67, and P53 expression and their effect on clinical outcome and response to therapy of non-muscle-invasive urothelial carcinoma. Materials and Methods: Fifty cases of non-muscle invasive urothelial carcinoma were collected; Top II, KI-67, and P53 expression was evaluated. Patients received treatment then tumor recurrence was correlated with the expression of previous markers. Results: There was a significant association between high Top II score, P53, and KI-67 and high tumor grade (P = 0.0001, 0.001, and 0.0001), submucosal infiltration (P = 0.0001 and 0.01), and recurrence (P = 0.01, 0.001, and 0.001). Conclusion: Top II, P53, and KI-67 may predict tumor response to therapy and the clinical outcome in non muscle-invasive urothelial carcinoma. PMID- 30303143 TI - BRAFV600E mutation in hairy cell leukemia: A single-center experience. AB - Background: BRAFV600E mutation has been reported as a unique genetic lesion of hairy cell leukemia (HCL), a subset of which lacks this lesion and shows adverse outcomes. Aims: To determine the prevalence of BRAFV600E in HCL from our center and derive clinicopathological correlation, if any. Materials and Methods: A 9 year retrospective analysis of 46 consecutive cases of HCL diagnosed on morphology and immunophenotyping was done. Stained smears were used as samples for amplification refractory mutation system polymerase-chain reaction using fluorescent primers for mutation detection. Results: BRAFV600E mutation was detected in 41/46 patients (89.1%) while absent in control samples of chronic lymphocytic leukemia. Cases mimicking HCL-variant clinically or immunophenotypically too showed the presence of this mutation. HCL with mutated BRAF presented at a younger age. No statistical difference in blood counts, tumor load, and immunophenotype patterns existed among BRAF mutated and unmutated group. Nine patients (45%) with mutated BRAF had residual disease following treatment with cladribine. Conclusion: BRAFV600E mutation analysis has a definitive role in the diagnosis of HCL. PMID- 30303144 TI - Student perception of peer teaching and learning in pathology: A qualitative analysis of modified seminars, fishbowls, and interactive classroom activities. AB - Context: Peer-assisted teaching and learning (PTL) is being experimented in different medical universities worldwide. It is a learner-centered approach involving students through active learning strategies. Aims: To study the student perception of PTL in methods such as group-led seminars and fishbowls, in classroom through various interactive activities; compare and find out the student acceptability and efficacy of each of these methods in learning conceptual topics such as various types of anemia. Subjects and Methods: Medical students of second-year professional course were subjected to PTL in classroom during allotted teaching hours for 10 successive sessions using group-led modified seminars, fishbowls, and different formality-level interactive activities such as street plays, prop sessions, quiz sessions, to make them understand the clinical features and presentation of different types of anemia through understanding of etio-pathogenesis. To ascertain the aspects that influenced learning, focus group discussions were conducted in small groups consisting of 14 students and one facilitator in each group. Qualitative thematic analysis was performed on transcripts of the audio recordings by authors. Results: The emerging themes from qualitative analysis of transcripts were pertaining to teacher, student, and organization. We found motivation, interest, and involvement of peer teacher, student behavior and collaboration, contact time between students and facilitator, preparation time, coherence with other curricular activities, group size and composition, suitability of topic for the kind of activity, and availability of material for preparation as few sub-aspects affecting learning. Conclusion: For PTL to be effective, adequate transfer of knowledge through good peer teacher involvement, learner receptiveness, and adequate contact time is needed. Proper preparation with suitability of topics for the type of activity, alignment of seminars with other activities, and course coherence are prerequisites for the same. PMID- 30303145 TI - Infective endocarditis due to Streptococci and Enterococci: A 3-year retrospective study. AB - Introduction: Infective endocarditis (IE) is an infection of the heart valves with an aggregation of bacteria in a fibrin plaque called vegetation. Aims and Objectives: This is a retrospective study of all infective endocarditis cases due to alpha haemolytic streptococci and enterococci. Methods: All cases of infective endocarditis cases due to alpha haemolytic streptococci and enterococci in a period of three years from 1st January 2010 to 31st December 2012 were included. Isolation of the same organism from more than one set of blood cultures was taken as a confirmed case of infective endocarditis. Clinical and serological parameters were recorded using a proforma. Results: Native valve endocarditis was more common with only five prosthetic valves being involved. Out of 89 clinically suspected cases of IE in the three years from Jan 2010 to Dec 2012, for which blood was sent for culture, 63(70.78%) samples were positive by culture. Of these, 42/63(66.66%) were due to alpha-lytic Streptococci, enterococci and rare gram positive cocci. The rare ones included Enterococcus gallinarum, abiotropha defective, Vagococcus fluvialis and Nutritionally Variant Streptococci(NVS). High level Aminoglycoside resistance(HLAR) was also encountered. The varied and important features of these isolates are discussed. Complications and treatment are described. Conclusion: From a clinical microbiology point of view, the major challenge faced by the microbiologist in diagnosis of IE is proper aseptic collection of sample before starting antibiotics with a need for multiple samples to detect and also to prove the causative organism. Sensitivity reporting can be a difficult task in the context of NVS, HLAR and gram positives that are slow growing. Congestive failure and embolisation occurs even when the antibiotic treatment is successful.When patients go in for complications, it is very rarely due to wrong antibiotics. PMID- 30303146 TI - The clinicopathologic and immunohistochemical features of villoglandular adenocarcinoma of uterine cervix. AB - Aim: Villoglandular adenocarcinoma (VGA) of the uterine cervix is a variant of endocervical adenocarcinoma. However, the clinicopathologic and immunohistochemical features of VGA are still unclear. The aim of this study was to investigate the clinicopathologic and immunohistochemical features of VGA. Materials and Methods: A total of 20 VGA patients were identified among 852 patients diagnosed with cervical cancer and enrolled in this study. The immunohistochemical levels of Ki-67, P53, P16, progesterone receptor (PR), carcinoembryonic antigen (CEA), vimentin (Vim), and estrogen receptor (ER) were measured by immunohistochemistry. Results: VGA was prevalent in younger women and presented favorable prognosis. Ki-67, P16, and CEA were highly expressed in VGA tissues, while PR expression was hardly to be detected. The positive rates of Ki 67, CEA, and P16 were 90.0%, 90.0%, and 85.0%, respectively, which were significantly higher compared with PR (5.0%, P < 0.001). In addition, the positive rates of P53, Vim, and ER in VGA tissues were 55.0%, 50.0%, and 40.0%, respectively. However, the expression levels of Ki-67, P53, P16, PR, CEA, Vim, and ER were not significantly associated with clinical features (P > 0.05). Conclusion: These data indicate that VGA is a rare cervical adenocarcinoma, which is prevalent in younger women, and presents favorable prognosis. Detection of Ki 67, P53, P16, PR, CEA, Vim, and ER would be beneficial for the diagnosis of VGA. PMID- 30303147 TI - Adult T-cell leukemia/lymphoma and acquired immunodeficiency syndrome - CD4+ T cell malignancy in CD4+ T-cell deficient status: A paradox. AB - CD4 counts along with viral loads are important parameters in the monitoring of human immunodeficiency virus (HIV) infection. Human T-cell lymphotropic virus type I (HTLV-I) is known to be an etiological agent for adult T-cell leukemia/lymphoma (ATLL). Coinfection of HTLV-I and HIV is well known in regions with high seroprevalence, and there is no published data in the Indian scenario. We present an interesting case of occurrence of CD4+ T-cell proliferation in a known beta thalassemia major with acquired HIV seropositivity accompanied by simultaneously increasing CD4+ counts and viral loads. Further workup revealed ATLL with an underlying HTLV infection. PMID- 30303148 TI - Chronic granulomatous disease presenting with small bone osteomyelitis in a young child: A case report. AB - Chronic granulomatous disease (CGD) is a life threatening inherited disorder with varied clinical presentations often characterized by recurrent bacterial and fungal infections along with widespread granulomatous tissue response. The disease results from phagocytic defects characterized by deficiencies in oxidative burst of neutrophils. Nitroblue tetrazolium reduction test (NBT) and Dihydrorhodamine (DHR) with PMA stimulation by flow cytometry are quick, simple, sensitive and specific laboratory tests that help establish early and reliable diagnosis of CGD with an overall improvement in survival and disease prognosis. We report a case of 2-year old child who presented with small bone osteomyelitis involving bilateral feet and was later diagnosed to have autosomal recessive CGD due to mutation in NCF1 gene. PMID- 30303149 TI - Immunohistochemical differentiation between spindle cell lipoma and neurofibroma of oral cavity using CD34 and SOX10. AB - Spindle cell lipoma (SCL), also called as pleomorphic adenoma, is a rare variant of lipoma histopathologically characterized by an admixture of mature fat cells with spindle cells and occasionally mast cells with myxoid connective tissue stroma and thick bends of birefringent collagen. Although buccal mucosa is the most common location for oral lipomas, for SCL, it is an exceedingly rare location. We report a case of an asymptomatic swelling of buccal mucosa that simulated the features of neurofibroma on histopathological examination, and the final diagnosis of SCL was made on the basis of immunohistochemical features. This is the first documentation of oral SCL using SOX10 to achieve the final diagnosis. PMID- 30303150 TI - Dedifferentiation of oncocytic epithelial-myoepithelial carcinoma to mucoepidermoid carcinoma in parotid gland: A rare case report. AB - Epithelial-myoepithelial carcinomas (EMCs) account for <1% of all salivary gland malignancies. Till now, 23 cases of dedifferentiated EMC have been reported to the best of our knowledge. However, dedifferentiation of oncocytic EMC to mucoepidermoid carcinoma is extremely rare. A 38-year-old female presented with right post aural swelling 4 cm * 2 cm in size for 6 months. Surgical excision was carried out, and we received partly skin-covered tissue 5 cm * 2 cm in size. Sections examined showed features of oncocytic EMC dedifferentiating into mucoepidermoid carcinoma. Myoepithelial component showed oncocytic change which was highlighted by p63. PMID- 30303151 TI - Cutaneous melanoma in childhood presenting as intraparotid lymph node metastasis. AB - Cutaneous melanoma in childhood is a rare disease. Rendering a clinical diagnosis of melanoma in pediatric patients is confounded by the fact that pigmented lesions in pediatric patients do not conform to the ABCDE rules applicable to adult patients. Furthermore, making a histologic diagnosis of cutaneous melanoma in childhood is also difficult with no universally accepted criteria applicable to pediatric melanomas. We report the case of a 5-year-old child presenting with intraparotid lymph node metastasis who was later found to have melanoma involving periorbital region. It is proposed that careful analysis of histologic features as well as the additional information provided by immunohistochemistry should allow for a correct diagnosis in most cases of melanoma in children. PMID- 30303152 TI - Bilateral submandibular swelling diagnosed as tuberculous lymphadenitis in an asymptomatic patient: A rare case report. AB - In India, tuberculosis (TB) is a prevalent systemic disease and number of people who die with TB is increasing year by year. TB can be life-threatening, and there is a high mortality rate of systemic infection with TB. Although extrapulmonary TB (EPTB) is a rare form of TB, its prevalence is increasing day-by-day. Reported here is a case of a 28-year-old female patient with a painless swelling bilaterally in the submandibular region. She was diagnosed with bilateral submandibular tuberculous lymphadenitis. Tuberculous lymphadenitis, when occurring in the cervical region, continues to be a common cause of EPTB. Thorough knowledge of this condition is important as it can help in early diagnosis leading to prompt treatment of the patient and prevent further complications. PMID- 30303153 TI - Pericardial mesothelioma presenting as chronic constrictive pericarditis. A series of three cases from a single institution. AB - Pericardial mesotheliomas are rare tumors which often present with features of constrictive pericarditis. We present clinical, imaging, histological, and immunohistochemical findings of three cases presenting with chronic constrictive pericarditis. Two of these cases were initially treated as tuberculous pericarditis. Histologically, all the three cases were of an epithelioid type and showed positivity for more than one mesothelial markers. Two patients had a fatal outcome, and one was lost to follow-up. PMID- 30303154 TI - Well-differentiated liposarcoma of the breast arising in a background of malignant phyllodes tumor in a pregnant woman: A rare case report and review of literature. AB - Pure mesenchymal sarcomas and phyllodes tumor with sarcomatous differentiation of the breast are rare tumors. Primary breast sarcomas are a heterogenous group of neoplasms which include malignant fibrous histiocytoma, fibrosarcoma, angiosarcoma, leiomyosarcoma, osteosarcoma, rhabdomyosarcoma, and liposarcoma. Sarcomatous differentiation in phyllodes tumor is seen in the form of angiosarcoma, chondrosarcoma, leiomyosarcoma, osteosarcoma, rhabdomyosarcoma, and liposarcoma. Here, we report a case of a 28-year-old pregnant woman with a breast lump during her second trimester which drastically increased in size in the postpartum period. Wide local excision revealed a malignant phyllodes tumor with liposarcomatous differentiation. Later, the patient underwent completion mastectomy which showed residual tumor. PMID- 30303155 TI - Duodenal gangliocytic paraganglioma: A rare cause for gastrointestinal polyp. AB - Duodenal gangliocytic paragangliomas are rare neoplasms often arising in the duodenum in close proximity to the ampulla of Vater. These neoplasms are considered to have a benign behavior with lymph node metastases being a rare phenomenon and distant metastases even more so. Although a standardized treatment has not been determined, a margin-free tumor resection seems to be the best treatment modality. We report herein the case of a 36-year-old female who presented with abdominal pain and was found to have a polyp in the second part of duodenum which was excised endoscopically. Histopathology and immunohistochemistry revealed characteristic features of this rare tumor. PMID- 30303156 TI - Gastric carcinoma and acute myeloid leukemia: A case report of a double malignancy. AB - A double malignancy involving a solid organ and hematopoieteic system is rare. We report an interesting case of gastric adenocarcinoma with subsequent development of acute myeloid leukemia, in the absence of any therapeutic intervention. PMID- 30303157 TI - An unusual case of hepatic lymphoma with multiple epithelial malignancies. AB - Primary hepatic mucosa-associated lymphoid tissue lymphoma (MALToma) is a rare entity. Its coexistence with other malignancies is even rarer. Only few case reports of its association with other malignancies mostly gastric and colon cancer have been published. We report a case of primary MALToma of liver in an unusual setting of dual solid malignancy. PMID- 30303158 TI - Adrenal medullary hyperplasia with coexistent cerebral angiomas. AB - Sporadic adrenal medullary hyperplasia (AMH) is a rare entity and mimics pheochromocytoma clinically as well as pharmacologically. It is characterized by increase in adrenal medullary cells with the expansion of cells into areas normally not seen. A 59-year-old male presented with chronic hypertension and raised 24-h urinary normetanephrine levels. Radiological and clinical possibility of pheochromocytoma led to left transperitoneal laparoscopic adrenalectomy. Histopathology, however, showed increase in adrenal medullary to cortical ratio, further confirmed by immunohistochemistry. The absence of any well-defined lesion led to the diagnosis of AMH. Furthermore, on routine imaging, two asymptomatic cavernous hemangiomas were seen. We present this case to reiterate that AMH is an entity which should be considered as a differential for pheochromocytoma. Furthermore, the presence of asymptomatic cavernous hemangiomas in the cerebrum, in this case, makes it rarer since this sporadic association is seldom seen. PMID- 30303159 TI - Primary intrauterine dysgerminoma in a pregnant woman: A rare case report. AB - Primary extraovarian dysgerminoma is very rare. Nearly all reported uterine germ cell tumors are nondysgerminoma. Herein, we reported a primary intrauterine dysgerminoma. A 21-year-old pregnant woman G2 L1 with a gestational age of 33 weeks referred to an obstetric ward with a chief complaint of labor pain and membrane rupture. Ultrasonography showed a large hypoechoic lobulated area adjacent to the lower part of her uterus. She underwent an operation and a huge mass was detected in her uterus, which was extended to her pelvic floor. Histopathological and immunohistochemical examinations were consistent with dysgerminoma. PMID- 30303160 TI - Polyp of the uterine cervix with heterologous fatty tissue. AB - This report documents an uncommon case of choristomatous cervical polyp containing fat tissue. The patient was a 24-year-old female who presented with irregular intermenstrual bleeding. On examination, a polypoid lesion with smooth outlines, measuring 1 cm in diameter was removed. Microscopic examination demonstrated abnormal fibrous stroma, devoid of endocervical glands, containing mature adipose tissue, and thick-walled blood vessels. The lesion was covered by a typical mature squamous cell outer lining. To the best of our knowledge, this is only the second report of an adipose tissue arising from the cervical wall. Further clinicopathologic considerations are needed to elucidate the origin of the fatty component in cervical polyps. PMID- 30303161 TI - Malignant Sertoli cell tumor of the testis masquerading as seminoma with bone metastasis. AB - Sex cord-stromal tumors of the testes are rare malignancies as compared to germ cell tumors. Pure Sertoli cell tumors are still rare representing <1% of testicular cancers and the malignant forms are too rare. Furthermore, the occurrence of metastasis in such cases is extremely rare with <30 cases reported in literature so far to the best of our knowledge. We present herein a case of malignant Sertoli cell tumor in a 48-year-old male who was initially misdiagnosed as seminoma based on histology and clinical presentation. Four months later, he presented with symptoms due to bony metastasis and found to have widespread metastatic disease which is a very rare presentation of Sertoli cell tumors. Diagnosis of sex cord-stromal tumor requires high index of suspicion as these tumors are most of the times misdiagnosed as germ cell tumors due to their rare incidence and atypical presentation leading to mismanagement. Timely diagnosis at an early stage can provide therapeutic benefit due to lack of well-defined treatment options at advanced stages. PMID- 30303162 TI - Orchitis: An unusual presentation of polyarteritis nodosa. AB - Polyarteritis nodosa (PAN), a systemic necrotizing vasculitis with multiorgan development, is generally restricted to the medium-sized muscular arteries. The varied initial clinical presentations of PAN can lead to a delayed diagnosis. We present the case of a middle-aged male patient who presented with an acute onset right-sided testicular pain as the initial clinical symptom with ischemic changes on ultrasonogram, thereby requiring orchiectomy. This was reported to be a case of tubercular epididymo-orchitis. On review, the biopsy revealed features of necrotizing arteritis as seen in PAN with fibrinoid necrosis and giant cells, thus highlighting the fact that vasculitis due to PAN may have a localized presentation at the time of diagnosis. PAN should be distinguished from other causes of epididymo-orchitis and other vasculitis lesions, the most common being tubercular etiology in the Asian population. PMID- 30303163 TI - Synovial hemangiomas of wrist and ankle joint: A report of two rare cases. AB - Synovial hemangioma is a rare, benign, vascular tumor of synovium leading to joint pain and swelling. The most common site is the knee joint, but rare cases involving other sites have also been reported. We report two rare cases of synovial hemangioma, one involving the ankle joint and other involving the wrist joint. Histopathology is the gold standard for diagnosis of these cases. Early treatment is warranted to prevent the risk of permanent joint damage. PMID- 30303164 TI - Keratomycosis due to Purpureocillium lilacinum: A case report from Sub-Himalayan region of Uttarakhand. AB - The fungus Purpureocillium lilacinum previously known as Paceliomyces lilacinus is an emerging pathogen that can cause severe human infections including devastating oculomycosis. Treatment with traditional antifungals often fails, and the organism shows variable susceptibility to novel triazoles. We hereby report a case of keratomycosis caused by Pur. lilacinum in an immunocompetent male patient following trauma. The patient was successfully treated with voriconazole. The drug shows good activity against Pur. lilacinum and could be a promising therapeutic alternative to treat infections caused by this fungus, which generally shows resistance to conventional antifungal agents including novel triazoles. PMID- 30303165 TI - Fibrillary glomerulonephritis in a human immunodeficiency virus-positive, hepatitis C-negative Indian patient: Expanding the profile of renal involvement in human immunodeficiency virus infection. AB - Highly active anti retroviral therapy (HAART) has dramatically improved life expectancy of human immunodeficiency virus (HIV) infected patients, converting HIV infection into a chronic illness with associated changes in its attendant renal complications. The past two decades have witnessed a decrease in the prevalence of HIV associated nephropathy (HIVAN), traditionally considered to be the hall mark of renal involvement in HIV infection. Simultaneously a host of other glomerular and tubulo-interstitial diseases have emerged, expanding the spectrum of HIV associated renal diseases, predominant among which is HIV associated immune complex mediated kidney diseases (HIVICK). Of the diverse glomerular diseases constituting HIVICK, fibrillary glomerulonephritis (FGN) remains a rarity, with only two existing reports to date, confined to patients co infected with Hepatitis C virus (HCV). The pathogenetic role of HIV in these patients remains under a cloud because of previously well established association of HCV infection and FGN. We report a case of FGN in a HIV seropositive, HCV negative Indian patient, highlighting the diagnostic electron microscopy (EM) findings of FGN and strengthening the causal association of HIV with FGN. In view of increasing heterogeneity of renal complications in HIV infection, the diagnostic utility of a comprehensive renal biopsy evaluation inclusive of EM is emphasized for appropriate selection of treatment modalities. PMID- 30303166 TI - Extensive trophoblastic differentiation in case of an endometrial carcinoma. AB - Trophoblastic differentiation of endometrial carcinoma is extremely rare, till date 18 cases reports are there in the literature. A 68-year-old postmenopausal female presented with abnormal vaginal bleeding. Histopathologically, there were areas of serous carcinoma with trophoblastic differentiation (~90%). On immunohistochemistry, the trophoblastic component was positive for beta-human chorionic gonadotropin (hCG), HPL and EMA. IHC confirmed the diagnosis of serous carcinoma with trophoblastic differentiation. The clinicopathological features of 18 previously reported cases of trophoblastic differentiation in the uterine tumor were analyzed in addition to the present case.

PMID- 30303179 TI - Laparoscopic Surgery Within an Enhanced Recovery after Surgery (ERAS) Protocol Reduced Postoperative Ileus by Increasing Postoperative Treg Levels in Patients with Right-Side Colon Carcinoma. AB - BACKGROUND The aim of this study was to determine the effects of laparoscopic surgery within an ERAS program on outcomes and immunological function in patients with a carcinoma in the right colon. MATERIAL AND METHODS Patient data were acquired from a prospectively maintained database, and 176 patients diagnosed with right colon carcinoma with surgery were selected from the database. These patients were divided into a laparoscopic group (Lap group, n=86) and an open operation group (Open group, n=90). All patients received treatment according to a standardized ERAS protocol. We collected data on CRP levels, CD4+/CD8+ ratios, and Treg values in peripheral blood, baseline and surgical characteristics, postoperative complications, and postoperative ileus (POI). RESULTS Circulating CD4+/CD8+ ratios and Treg values were decreased and CRP levels were increased in both groups after the operation. However, the values in the Lap group patients recovered much more quickly than those of patients in the Open group (P<0.05). Patients undergoing laparoscopic surgery had significantly less preoperative bleeding (P<0.01), reduced ratio of overall POI (mainly early ileus), and shorter postoperative hospital stay (P=0.03). Multivariate logistic regression analysis showed that POD1 Treg value was an independent predicator for postoperative ileus in patients with right colon carcinoma resection. CONCLUSIONS In patients with a carcinoma in the right colon, laparoscopic surgery within an ERAS protocol leads to better immunity preservation after surgery, and POD1 Treg value may be an independent predicator for postoperative ileus, which could, at least in part, explain the shorter hospital stay after surgery.

It represents a quarter of the London population. And other 16 thousand are the deaths in the Mediterranean Sea in four years. Yet, there are those who still talk about invasion, making it a weapon for political propaganda, and the health sector is among the most exploited. The Italian politicians themselves are at the forefront on the diffusion of fake news on the health conditions of people arriving in Europe, riding the long wave of fear of the unknown foreign people, and of the possibility of a contagion. However, data tell a completely different story: migrants who arrive in Europe does not bring vulnerability to the natives: they are vulnerable, and they need first of all our protection. There is no evidence of outbreaks of infectious diseases, and in any case border controls are carried out, and they can identify anyone who is not in good health before landing. The same can not be said of mental illness. Rape, torture, murders: this is what people arrived in Italy from Libya have lived. This should be the starting point - not the refusal to give hospitality - for aligning our communities with the UN warning from here until 2030: no one left behind. PMID- 30303183 TI - [Systems medicine and complexity: rethinking health management and hospital modelling.] AB - We have reached the awareness that diseases, far from being simple altered health states, are characterized by intrinsic emerging and adaptive properties, requiring an interdisciplinary, global and systemic approach, oriented towards integration and coordination, rather than an atomic and disintegrated logic. A new approach is needed, "systems medicine", defined as an interdisciplinary field of study that looks at the systems of the human body as part of an integrated whole, incorporating biochemical, physiological, and environment interactions. This new kind of medicine addresses diseases and their interrelationships in a scale invariant, holistic and systematic "multi-axial" way, analysing apparati, organs, tissues, cells, molecules, always taking care of the relationships with the relative ecosystem. Given this dramatic change in the process of learning, investigating and approaching diseases, the hospital itself has to evolve continuously, changing strategies and structures. Hospital management has to be re-designed and re-configured in order to face and govern complex systems. Health management today must be flexible, able to absorb and incorporate complexity, and learn from it, reinforcing itself. Complexity must not be avoided. It is, indeed, an opportunity to be considered in the strategic planning and programming processes. Intuition, creativity and flexibility are the abilities and competences of a manager in a complex environment. PMID- 30303184 TI - [ROBIS: a new tool to assess risk of bias in systematic reviews was developed.] AB - OBJECTIVE: To develop ROBIS, a new tool for assessing the risk of bias in systematic reviews (rather than in primary studies). STUDY DESIGN AND SETTING: We used four-stage approach to develop ROBIS: define the scope, review the evidence base, hold a face-to-face meeting, and refine the tool through piloting. RESULTS: ROBIS is currently aimed at four broad categories of reviews mainly within health care settings: interventions, diagnosis, prognosis, and etiology. The target audience of ROBIS is primarily guideline developers, authors of overviews of systematic reviews ("reviews of reviews"), and review authors who might want to assess or avoid risk of bias in their reviews. The tool is completed in three phases: 1) assess relevance (optional), 2) identify concerns with the review process, and 3) judge risk of bias. Phase 2 covers four domains through which bias may be introduced into a systematic review: 1) study eligibility criteria; 2) identification and selection of studies; 3) data collection and study appraisal; and 4) synthesis and findings. Phase 3 assesses the overall risk of bias in the interpretation of review findings and whether this considered limitations identified in any of the phase 2 domains. Signaling questions are included to help judge concerns with the review process (phase 2) and the overall risk of bias in the review (phase 3); these questions flag aspects of review design related to the potential for bias and aim to help assessors judge risk of bias in the review process, results, and conclusions. CONCLUSIONS: ROBIS is the first rigorously developed tool designed specifically to assess the risk of bias in systematic reviews. PMID- 30303185 TI - ? PMID- 30303186 TI - ?

However, the pharmacological treatment of depression, during pregnancy generates a lot of concerns about the risks of such treatment for the fetus development and the neonatal health. The aim of this review is to present a selection of the latest international literature including recent original studies, systematic reviews, meta-analyses and recommendations from the guidelines, both on the risks of an untreated depressive disorders and on the risk of antidepressant therapy during gestation with drugs belonging to the SSRI and SNRI (SRI) class. An updated information of the recent risk-benefit data of these drug treatments in women with affective disorders in pregnancy may actually enable better and more conscious management of these disorders, not only for those working in the mental health field but also for general practitioners and those of other medical specialties. PMID- 30303188 TI - [Dementia in the real world.] AB - More than with other diseases, the diagnosis of dementia must be made carefully, as it can have a huge impact on both the patient's social and legal status and the caregiver's own health. Special attention should be put in avoiding diagnostic errors at the time of symptom onset, because a diagnosis made explicitly can affect the patient's self-esteem. If the diagnosis is uncertain, we would recommend not performing unnecessary investigation but rather waiting to get a clearer clinical picture. Dementia, unfortunately, is reversible or partially reversible by drug therapy only in very few cases. We here describe common diagnostic challenges and doubts, and how to manage patients with known dementia in relation to changes in the environment and social interactions. Dementia strongly affects a person's well-being, including maintaining a social life and interpersonal relationships, with either the caregiver and the family. PMID- 30303189 TI - ?

INTRODUCTION: The increasing number of Emergency Department (ED) admittances coupled with the limited availability of hospital beds requires a patients classification according their intensity of care. Among the available classification systems the Tri-Co (Corridor triage) system, could fit ED patients and was therefore progressively adapted and tested to be used in the ED. AIM: To assess the correct allocation of patients according to the intensity of care. METHODS: Eight versions of the Tri-Co were progressively modified and tested. The Final Modified Tri-Co system was used in 111 randomly selected index days, in different time slots, on all adult patients admitted to ED from May to November 2017 and allocated according to the traditional system (1008 observations). RESULTS: The vast majority of patients (88%) was placed in a section adequate to their intensity of care; 8% in a sector with higher and 4% with lower intensity of care compared to their needs. The comparison between the allocation based on clinical assessment and Tri-Co scores highlighted the reliability of the Tri-Co. The alpha Crombach of the modified IDA scale was 0.724. CONCLUSIONS: The Modified Tri-Co system allows the early classification of patients and their assignment to the adequate level of care.

Extent and type of implicit rationing of nursing care in seven South Tyrolean hospitals: a descriptive study. INTRODUCTION: Implicit rationing of nursing care is an international phenomenon, defined as withholding of or failure to carry out necessary nursing interventions due to a lack of nursing resources. AIMS: To describe the extent and type of nursing care implicitly rationed in South Tyrolean hospitals, and to explore differences across clinical areas and between registered nurses (RNs) and support staff. METHODS: The Basel Extent of Rationing of Nursing Care (BERNCA) questionnaire was completed between September and November 2015, by 934 RNs and support staff of the seven hospitals, involved in direct adult patient care (24 medical, 13 surgical, 5 rehabilitation, 4 intensive care units). Descriptive and explorative analyses were performed. RESULTS: The most rationed activities concerned "nursing care planning" (37.3%), "surveillance of confused patient" (30.7%), "providing emotional support" (30.1%) and "talking with patients and family" (28.4%). Of the ten most rationed activities, seven were common to RN and support staff, and across clinical areas, although with different frequencies. Significant differences between clinical areas were observed for: "nursing care planning", "rehabilitation care", and "comfort/talking with patients and family". DISCUSSION: Implicit rationing of nursing care occurs in South Tyrolean hospitals, mainly related to care planning and documentation. Higher priority is given to activities related to direct patient care. Further investigations on priority setting to increase the awareness among frontline nurses of what is rationed, and to guarantee the safety and quality of care is warranted.

INTRODUCTION: To date missed care have been described mostly in hospitals and data on nursing homes (NH) are missing. AIM: To describe missed care in NH residents identifying their perceived impact and seriousness. METHODS: A pilot study was conducted in 10 Piedmont NHs. For each omitted or delayed care on 20 residents observed for 3 consecutive days, the nurses provided information on the type of care, and information on the residents and on the organization were collected. RESULTS: Twenty-three nurses reported 57 missed care for 44/200 residents (22%; median 5 for each NH, range 0 13). Twenty-five missed/omitted care on 20 residents were considered of medium/high severity: 14 (56%) involved drug therapies and 5 (20%) the monitoring of vital signs. The level of severity derived from the distress caused to the resident, the risk of deterioration of residents'conditions and the repeated omissions on the same resident. Of the 32 missed care on 25 residents, judged of limited impact, the more frequent were dressing changes (12, 37.5%), and drugs administration (10, 31.3%). The most frequent reasons for delay/omission were unplanned events (16, 28.1%), shortage of nurses (12, 21.1%), and residents' clinical conditions (9, 15.7%). CONCLUSIONS: Missed care occur also in NHs. If staff shortage play a key role among potentially modifiable factors, a sizeable number of omission is associated to unlikely forseeable or avoidable events.

The nurses of the Ospedale Maggiore of Milan during the First World War. Peace, rights and dignity of work. INTRODUCTION: During the First World War the Hospitals of the big cities had to care for the people injured in the war places. To face this challenge, important changes in the internal organization had to be implemented. OBJECTIVE: To investigate how the First World War changed the working conditions of the nurses on duty at the Ospedale Maggiore and to contribute to outline the professional identity during the years of the conflict. METHODS: The correspondence between the female nursing staff and the hospital administration in the time span between from 1915 to 1918 was examined. The documents were retrieved in the historical archive of the Ospedale Maggiore from November 2017 to march 2018 and were analyzed through the methodology of historic research according to Chabod. RESULTS: During the First World War the nurses asked the hospital administration for changes of their working conditions, which had become unbearable because of the conflict. They obtained improvements concerning: a reduction in nightshift work hours, the employment of 86 nurses to guarantee a day off every ten days, replacement of staff in case of absence, increase in salary, paid sick leave. CONCLUSIONS: The nurses of the Ospedale Maggiore of Milan during the First World War, hoping for peace, stood out for their diligence in the care of the sick both civilians and militaries. Besides, they managed to obtain the recognition of they rights and dignity in the workplace.

Missed nursing care and italian nursing practice: preliminary findings of a consensus conference. In recent years in Italy there has been renewed interest in missed nursing care due to various factors, such as participation in the RANCARE project, with 28 European and non-EU countries, the opportunity to develop international exchanges, specific projects and field based research. We explored a range of ideas and processes, culminating in a conference designed to address specific issues relating to missed nursing care, in the Italian nursing practice. After a preliminary review of the literature on the psychometric properties of the available tools, with the intent of further deepening our understanding of the concept of missed nursing care, its implications for practice, management, education and research. After two days of presentations and discussions, the more than participating nurses agreed on a set of preliminary recommendations regarding missed nursing care and Italian nursing practice. This paper reports on the preliminary consensus findings from the conference. PMID- 30303199 TI - Quantifying the influence of the ion cloud on SAXS profiles of charged proteins. AB - Small-angle X-ray scattering (SAXS) is a popular experimental technique used to obtain structural information on biomolecules in solution. SAXS is sensitive to the overall electron density contrast between the biomolecule and the buffer, including contrast contributions from the hydration layer and the ion cloud. This property may be used advantageously to probe the properties of the ion cloud around charged biomolecules. However, in turn, contributions from the hydration layer and ion cloud may complicate the interpretation of the data, because these contributions must be modelled during structure validation and refinement. In this work, we quantified the influence of the ion cloud on SAXS curves of two charged proteins, bovine serum albumin (BSA) and glucose isomerase (GI), solvated in five different alkali chloride buffers of 100 mM or 500 mM concentrations. We compared three computational methods of varying physical detail, for deriving the ion cloud effect on the radius of gyration Rg of the proteins, namely (i) atomistic molecular dynamics simulations in conjunction with explicit-solvent SAXS calculations, (ii) non-linear Poisson-Boltzmann calculations, and (iii) a simple spherical model in conjunction with linearized Poisson-Boltzmann theory. The calculations for BSA are validated against experimental data. We find favorable agreement among the three computational methods and the experiment, suggesting that the influence of the ion cloud on Rg, as detected by SAXS, may be predicted with nearly analytic calculations. Our analysis further suggests that the ion cloud effect on Rg is dominated by the long-range distribution of the ions around the proteins, as described by Debye-Huckel theory, whereas the local salt structure near the protein surface plays a minor role. PMID- 30303200 TI - Monte Carlo simulation on the dynamics of a semi-flexible polymer in the presence of nanoparticles. AB - The dynamics of a semi-flexible polymer chain in the presence of periodically distributed nanoparticles is simulated by using off-lattice Monte Carlo simulations. For repulsive or weak attractive nanoparticles, the dynamics are slowed down monotonically by increasing the chain stiffness ktheta or decreasing the inter-particle distance d. For strong attractive nanoparticles, however, the dynamics show nonmonotonic behaviors with ktheta and d. An interesting result is that a stiff polymer may move faster than a flexible one. The underlying mechanism is that the nanoparticle's attraction is weakened by the chain stiffness. The nonmonotonic behavior of the polymer's dynamics with ktheta is explained by the competition between the weakening effect of the chain stiffness on the nanoparticle's attraction and the intrinsic effect of chain stiffness which reduces the dynamics of the polymer. In addition, the nonmonotonic behavior of the polymer's dynamics with d is explained by the competition between the nanoparticle-exchange motion of the polymer dominated at small d and the desorption-and-adsorption motion at large d. The excluded volume effect of the nanoparticles plays a more important role for stiffer polymers as the attraction of the nanoparticles is weakened by the chain stiffness.

AB - Supported MnO2-based nanomaterials were fabricated on fluorine-doped tin oxide substrates using plasma enhanced-chemical vapor deposition (PE-CVD) between 100 degrees C and 400 degrees C, starting from a fluorinated Mn(ii) diamine diketonate precursor. Growth experiments yielded beta-MnO2 with a hierarchical morphology tuneable from dendritic structures to quasi-1D nanosystems as a function of growth temperature, whose variation also enabled a concomitant tailoring of the system fluorine content, and of the optical absorption and band gap. Preliminary photocatalytic tests were aimed at the investigation of photoinduced hydrophilic (PH) and solid phase photocatalytic (PC) performances of the present nanomaterials, as well as at the photodegradation of Plasmocorinth B azo-dye aqueous solutions. The obtained findings highlighted an attractive system photoactivity even under visible light, finely tailored by fluorine content, morphological organization and optical properties of the prepared nanostructures. The results indicate that the synthesized MnO2 nanosystems have potential applications as advanced smart materials for anti-fogging/self-cleaning end uses and water purification. PMID- 30303202 TI - Kinetic pathways towards mass production of single crystalline stanene on topological insulator substrates. AB - As a highly appealing new member of the two-dimensional (2D) materials family, stanene was first epitaxially grown on a three-dimensional topological insulator of Bi2Te3; yet, to date, a standing challenge is to drastically improve the overall quality of such stanene overlayers for a wide range of potential applications in next-generation quantum devices. Here we use state-of-the-art first-principles approaches to explore the atomistic growth mechanisms of stanene on different Bi2Te3(111)-based substrates, with intriguing discoveries. We first show that, when grown on experimentally studied Te-terminated Bi2Te3, stanene would follow an unusual partial-layer-by-partial-layer growth mode, characterized by short-range repulsive pairwise interactions of the Sn adatoms; the resultant stanene overlayer is destined to contain undesirable grain boundaries. More importantly, we find that stanene growth on Bi2Te3(111) pre-covered with a Bi bilayer follows a highly desirable nucleation-and-growth mechanism, strongly favoring single crystalline stanene. We further show that both systems exhibit pronounced Rashba spin-orbit couplings, while the latter system also provides new opportunities for the potential realization of topological superconductivity in 2D heterostructures. The novel kinetic pathways revealed here will be instrumental in achieving the mass production of high-quality stanene with emergent physical properties of technological significance. PMID- 30303203 TI - Multi-segmented CdS-Au nanorods for electrochemiluminescence bioanalysis. AB - In this study, we have developed a programmable electrochemiluminescence (ECL) system based on multi-segmented CdS-Au nanorod arrays with a sequential and highly tunable structure. The nanorod arrays were synthesized by an electrodeposition method using anodic aluminum oxide (AAO) as the template in which the Au and CdS segments were alternately electrodeposited. Compared to pure CdS nanorod arrays, multi-segmented CdS-Au nanorod arrays have showed a better ECL performance, which can be attributed to two factors: the favorable electron transfer and the surface plasma resonance (SPR) effect of the Au segment. On the one hand, we demonstrated that the Au segment can increase the charge transfer rate of CdS, which is beneficial for the ECL process because the generation of the radical state needs to accept electrons and then generate the radical state. On the other hand, the SPR of Au plasmon-induced local electromagnetic field enhancement can increase the radiative decay rate of CdS which makes the ECL process more efficient and lead to a higher ECL intensity. And also, an ECL sensor with multi-segmented CdS-Au nanorod arrays was constructed to detect prostate protein antigen (PSA). This study provides some basis for designing high performance ECL emission materials and the construction of biosensors. PMID- 30303204 TI - Development of a selective and highly sensitive fluorescence assay for nucleoside triphosphate diphosphohydrolase1 (NTPDase1, CD39). AB - Ecto-nucleoside triphosphate diphosphohydrolase1 (NTPDase1, CD39) is a major ectonucleotidase that hydrolyzes proinflammatory ATP via ADP to AMP, which is subsequently converted by ecto-5'-nucleotidase (CD73) to immunosuppressive adenosine. Activation of CD39 has potential for treating inflammatory diseases, while inhibition was suggested as a novel strategy for the immunotherapy of cancer. In the present study, we developed a selective and highly sensitive capillary electrophoresis (CE) assay using a novel fluorescent CD39 substrate, a fluorescein-labelled ATP (PSB-170621A) that is converted to its AMP derivative. To accelerate the assays, a two-directional (forward and reverse) CE system was implemented using 96-well plates, which is suitable for the screening of compound libraries (Z'-factor: 0.7). The detection limits for the forward and reverse operation were 11.7 and 2.00 pM, respectively, indicating a large enhancement in sensitivity as compared to previous methods (e.g. malachite-green assay: 1 000 000-fold, CE-UV assay: 500 000-fold, fluorescence polarization immunoassay: 12 500-fold). Enzyme kinetic studies at human CD39 revealed a Km value of 19.6 MUM, and a kcat value of 119 * 10-3 s-1 for PSB-170621A, which shows similar substrate properties as ATP (11.4 MUM and 82.5 * 10-3 s-1). The compound displayed similar properties at rat and mouse CD39. Subsequent docking studies into a homology model of human CD39 revealed a hydrophobic pocket that accommodates the fluorescein tag. PSB-170621A was found to be preferably hydrolyzed by CD39 as compared to other ectonucleotidases. The new assay was validated by performing inhibition assays with several standard CD39 inhibitors yielding results that were consonant with data using the natural substrates. PMID- 30303205 TI - Hyphenation of high-temperature liquid chromatography with high-pressure electrospray ionization for subcritical water LC-ESI-MS. AB - High-pressure electrospray ionization (HP-ESI) performed under super-atmospheric pressure allows a stable and efficient electrospray of pure aqueous and/or superheated solutions even under a MUL min-1 flow rate regime. In this paper, we report the direct coupling of the HP-ESI source to high-temperature liquid chromatography (HT-LC) operated at <=30 MUL min-1 flow rates. In addition to ESI, the ion source functions as a back-pressure regulator to keep the mobile phase in the liquid phase when the column is heated to >100 degrees C. Under an ion source pressure of 7 bar, the LC column can be operated up to 160 degrees C. LC is performed under isocratic elution, and besides the isothermal mode, the temperature of the column can also be programmed to increase the selectivity while keeping the ion source at a constant temperature. For a given solution flow rate, the analytical time can be shortened by increasing the column temperature. HT-LC-ESI-MS using pure water as the mobile phase with a capillary column is also demonstrated.

AB - Pt/Bi2MoO6 nanoplates are efficient photocatalysts for the selective oxidation of saturated C-H bonds in alkyl aromatics under visible light illumination using O2 as an oxidant.

AB - We studied dispersants for exfoliating bulk V2Se9 into one dimensional chain units. V2Se9, with a negative zeta potential of -30.1 mV, was acidic and strongly anchored with the amine head of octadecylamine by charge transfer reaction. The steric hindrance by the octadecyl tail promoted the dispersion of V2Se9 to the nano level. PMID- 30303208 TI - C50Cl10, a planar aromatic fullerene. Computational study of 13C-NMR chemical shift anisotropy patterns and aromatic properties. AB - The isolated-pentagon-rule (IPR) is a prime determinant of fullerene stabilization accounting for the difficult isolation of hollow Cn (n < 60) species. In this connection, the isolation and structural characterization of D5h C50Cl10 as an IPR-violating fullerene are of interest owing to the study of factors providing further stability. Herein, we use DFT calculations to explore its aromatic behavior. In this connection the C50Cl10 structure is considered as a fullerene displaying a planar-aromatic character provided by the face-to-face disposition of two IPR structural motifs, mediated by ten exobonded sp3-carbons. In addition, the D5h-C50Br10 counterpart appears to be another promising structure as the target for explorative synthesis. Owing to the curvature of its IPR motif, an interesting variation in the 13C-NMR patterns relative to corannulene is described, where the relation between CI and CII signals is useful to evaluate the degree of the curvature of the pi-surface. The charge distribution of C50Cl10 reveals a more electron-deficient IPR dome in comparison to C60, envisaging an enhanced chemistry related to bare fullerenes. In addition, the -Cl and -Br exobonded atoms provide effective sigma-holes, suggesting such oblate fullerenes as interesting two-dimensional five-fold symmetric synthons useful for the formation of supramolecular species. Hence, an interesting chemistry and supramolecular array derivatives are potential applications to be further explored towards the development of novel nano-devices. PMID- 30303209 TI - Size exclusion effect in binary inclusion compounds of alpha-cyclodextrin. AB - The size exclusion of guests by alpha-cyclodextrin (aCD) in binary host-guest systems was observed to be a key structure-property relationship for the choice of this host as a receptor. For this, vapor sorption isotherms of water and volatile organic compounds were determined using dry aCD, which show an inclusion threshold by sorbate activity corresponding to a phase transition of guest (or water) inclusion. These phase transitions were also characterized using X-ray powder diffractograms. The analysis of these data shows that interaction of aCD with water does not differ much from that with organic compounds that can be included by aCD without water and therefore are water-mimicking as such. The inclusion and hydration Gibbs energies and composition of the saturated host guest clathrates were determined from sorption isotherms. The Gibbs energies of guest inclusion by solid aCD and its hydration characterize the guest-host and water-host affinity in the solid state. The correlation of the obtained inclusion parameters with that of guest size indicate the ban on the inclusion of volatile hydrophilic organic compounds with more than three carbon atoms and smaller molecules without hydrophilic groups. These data may be used for estimation of the relative ability of more hydrophobic guests to replace water and organic solvents in solid aCD. The observed inclusion of water and small hydrophilic molecules by solid aCD with phase transition gives an alternative insight into the role of water in activating the inclusion of more hydrophobic guests. Furthermore, the results show the extent to which aCD may be preferable in applications using water or other solvents. PMID- 30303210 TI - A unique metallic phase of H3S at high-pressure: sulfur in three different local environments. AB - We propose a new metallic phase (R3[combining macron]m, Z = 24) for H3S in a large pressure interval (~108-166 GPa) using an evolutionary crystal structure search algorithm combined with first-principles calculations. This structure consists of SH6, SH3 and S units which are connected through strong SH hydrogen bonds. It supports four-types of SH hydrogen-bonds that symmetrize at ~166 GPa. This is the only phase in the H-S family where sulfur exists in three different local environments. Sulfur in SH6 behaves as a cation, like in the SF6 molecule, whereas other sulfurs behave as anions. Hydrogens in SH6 behave like halogens (anions) whereas other hydrogens behave like alkalis (cations). The new structure has a substantially smaller DOS at the Fermi-level in comparison to earlier structures R3m and Im3[combining macron]m. This implies a lower superconducting temperature (TC) for the new phase and thus questions the validity of earlier high-TC explanations. We also find that S-H covalent bonds are different from the B-B bonds of MgB2. PMID- 30303211 TI - Comparing the reactivity of isomeric phosphinoferrocene nitrile and isocyanide in Pd(ii) complexes: synthesis of simple coordination compounds vs. preparation of P chelated insertion products and Fischer-type carbenes. AB - Isomeric phosphinoferrocene ligands, viz. 1'-(diphenylphosphino)-1-cyanoferrocene (1) and 1'-(diphenylphosphino)-1-isocyanoferrocene (2), show markedly different coordination behaviours. For instance, the reactions of 1 with [PdCl2(MeCN)2] and [(LNC)Pd(MU-Cl)]2 (LNC = [2-(dimethylamino-kappaN)methyl]phenyl-kappaC1) produced the "phosphine" complexes [PdCl2(1-kappaP)2] (7) and [(LNC)PdCl(1-kappaP)] (8), and the latter was converted into the coordination polymer [(LNC)Pd(MU(P,N) 1)][SbF6] (9). Conversely, the reaction of 2 with [(LNC)Pd(MU-Cl)]2 involved coordination of the phosphine moiety and simultaneous insertion of the isocyanide group into the Pd-C bond, giving rise to the P,eta1-imidoyl complex [PdCl(Ph2PfcN[double bond, length as m-dash]CC6H4CH2NMe2-kappa3C,N,P)] (10; fc = ferrocene-1,1'-diyl). Compound 10 was further transformed into the Fischer carbene [PdCl(Ph2PfcN(Me)CC6H4CH2NMe2-kappa3P,C,N)][BF4] (11) by methylation with [Me3O][BF4]. The reactions of 2 with Pd-Me and Pd(eta3-allyl) precursors also led to imidoyl complexes [Pd(MU-Cl)(Ph2PfcN[double bond, length as m-dash]CR kappa2C,P)]2 (R = Me: 12, R = allyl: 15), which were cleaved with PPh3 into the corresponding monopalladium complexes [PdCl(PPh3)(Ph2PfcN[double bond, length as m-dash]CR-kappa2C,P)] (R = Me: 13, R = allyl: 16). The treatment of 12 and 15 with thallium(i) acetylacetonate (acac) produced [Pd(acac-O,O')(Ph2PfcN[double bond, length as m-dash]CR-kappa2C,P)] (R = Me: 17, R = allyl: 18). Through proton transfer, these complexes reacted with Ph2PCH2CO2H, ultimately producing bis chelate complexes [Pd(Ph2PCH2CO2-kappa2O,P)(Ph2PfcN[double bond, length as m dash]CR)] (R = Me: 19, R = prop-1-enyl (sic!): 20). In addition, compound 13 was converted into the P-chelated carbene [PdCl(PPh3)(Ph2PfcN(Me)CMe-kappa2C,P)][BF4] (14). Compounds 10, 11, 13 and 14 were studied by cyclic voltammetry and by DFT computations. PMID- 30303213 TI - Dynamics and kinetics of the reaction OH + H2S -> H2O + SH on an accurate potential energy surface. AB - The dynamics and kinetics of the prototypical hydrogen abstraction reaction OH + H2S -> H2O + SH were studied using the quasi-classical trajectory approach on a new accurate ab initio potential energy surface (PES) for the ground electronic state. The PES was developed by fitting 82 680 ab initio points at the level of UCCSD(T)-F12a/aug-cc-pVTZ using the fundamental invariant-neural network method. On one hand, excitation of either the symmetric stretching mode or the asymmetric stretching mode of the reactant H2S almost equivalently enhances the reaction. The promotional effect of exciting the bending mode of H2S is not as strong as exciting the stretching modes while it increases with the collision energy. On the other hand, the calculated vibrational state distribution of the product H2O based on the normal mode analysis method agrees reasonably well with the earlier experimental result, which was rationalized by the underlying reaction mechanisms. In addition, the rate constants of the reaction have a non-Arrhenius temperature dependence. PMID- 30303214 TI - Long-lived triplet excited state in a platinum(ii) perylene monoimide complex. AB - We report the synthesis and solution based photophysical properties of a new Pt(ii)-terpyridine complex coupled to a perylene monoimide (PMI) chromophoric unit through an acetylene linkage. This structural arrangement resulted in quantitative quenching of the highly fluorescent PMI chromophore by introducing metal character into the lowest energy singlet state, thereby leading to the formation of a long-lived PMI-ligand localized triplet excited state (tau = 8.4 MUs). Even though the phosphorescence from this triplet state was not observed, highly efficient quenching of this excited state by dissolved oxygen and the observation of singlet oxygen photoluminescence in the near-IR at 1270 nm initially pointed towards triplet excited state character. Additionally, the coincidence of the excited state absorbance difference spectra from the sensitized PMI ligand using a triplet donor and the Pt-PMI complex provided strong evidence for this triplet state assignment, which was further supported by TD-DFT calculations. PMID- 30303217 TI - Synthesis of complementary hierarchical structured Si/C composites with high Si content for lithium-ion batteries. AB - Si/C composites are considered as the most promising anode materials for next generation lithium-ion batteries (LIBs) due to their high specific capacity and low cost. However, the commercialized Si/C composites cannot maintain a Si content over 10 wt% for sustaining an acceptable cycle life. To achieve long-term cycle stability for Si/C composites with high Si content is still very challenging. Here, we report a rationally designed double-morphology Si/graphene (DMSiG) composite with a high Si content of 78 wt%, and prove its feasibility as a high performance anode material for LIBs. DMSiG composes of Si quantum-dot decorated graphene and mesoporous Si spheres with a complementary hierarchical structure. The graphene framework enhances the electronic conductivity, alleviates the aggregation of mesoporous Si spheres and provides space and flexibility to buffer the volume change during cycling. Mesoporous Si spheres contribute to a large reversible capacity and support the hierarchical architecture of DMSiG. The Si quantum-dots help to build firm connections between graphene and mesoporous Si spheres to avoid their separation during cycling. Coupling these features together, the DMSiG anode delivers a high reversible capacity of 1318 mA h g-1 at a current density of 500 mA g-1 and 684 mA h g-1 at 2000 mA g-1.

AB - A two-step synthetic route using RE(OH)CO3 colloid spheres as the sacrificial template was designed to prepare monodisperse, pure bastnasite (RECO3F: RE = Ce, La, Pr, Nd) with a hole structure for the first time. A variety of morphologies, including jujube core-like, stacked nanoblocks, and stacked nanosheets were obtained through changing the ratio of reactants. The phase, structure, shapes, and photoluminescence properties of samples were characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and photoluminescence (PL) spectroscopy. The CeCO3F:Ln3+ (Ln = Tb, Eu, Dy) phosphors give green, yellow and blue emission, respectively, due to the f-f transitions of Ln3+ ions. Furthermore, the energy transfer from Ce3+ to Dy3+ and Tb3+ was described in detail. PMID- 30303219 TI - Stable-radicals increase the conductance and Seebeck coefficient of graphene nanoconstrictions. AB - Nanoscale thermoelectricity is an attractive target technology, because it can convert ambient heat into electricity for powering embedded devices in the internet of things. We demonstrate that the thermoelectric performance of graphene nanoconstrictions can be significantly enhanced by the presence of stable radical adsorbates, because radical molecules adsorbed on the graphene nanoconstrictions create singly-occupied orbitals in the vicinity of Fermi energy. This in turn leads to sharp features in their transmission functions close to Fermi energy, which increases the electrical conductance and Seebeck coefficient of the nanoconstrictions. This is a generic feature of radical adsorbates and can be employed in the design of new thermoelectric devices and materials.

The cyclic voltammogram of derivative 1 contains two oxidative processes and one reductive redox process as well as an additional multi-electron wave at high negative potentials above -2 V, which can involve both the ligand and metal center. One-electron oxidation of 1 by silver triflate produces the [(imSQC(O)Ph)CoII(imQC(O)Ph)]OTf.2toluene (2) derivative with the trigonal prismatic coordination environment of the metal arising from the additional coordination of -C(O)Ph hemilabile groups. This is a first example of a trigonal prismatic coordination polyhedron in cobalt-based complexes featuring o-iminobenzoquinone ligands. The trigonal prismatic geometry achieved by the unique flexibility of the ligand allows metal-to-ligand redox induced electron transfer (RIET). Chemical oxidation of complex 1 promotes the reduction of CoIII to CoII in compound 2 due to the redox-active nature of o iminobenzoquinonate ligands. Remarkably, this is the first example of RIET in cobalt-based derivatives with this type of ligand. The oxidative states of the ligands and cobalt ion in both complexes were unequivocally established according to the X-ray data collection by using the utility of "metric oxidation state" (MOS). The spin states of the metal centers were unambiguously determined by density functional theory. The strong antiferromagnetic exchange via metal-ligand interactions is dominant in compounds 1 and 2, giving the doublet (S = 1/2) and triplet (S = 1) ground spin state, respectively.

AB - Cysteine plays an essential role in maintaining cellular redox homeostasis and perturbations in cysteine concentration are associated with cardiovascular disease, liver disease, and cancer. 19F MRI is a promising modality for detecting cysteine in biology due to its high tissue penetration and negligible biological background signal. Herein we report fluorinated macrocyclic copper complexes that display a 19F NMR/MRI turn-on response following reduction of the Cu(ii) complexes by cysteine. The reactivity with cysteine was studied by monitoring the appearance of a robust diamagnetic 19F signal following addition of cysteine in conjunction with UV-vis and EPR spectroscopies. Importantly, complexes with CH2CF3 tags display good water solubility. Studies with this complex in HeLa cells demonstrate the applicability of these probes to detect cysteine in complex biological environments. PMID- 30303224 TI - The impact of substrate surface defects on the properties of two-dimensional van der Waals heterostructures. AB - The recent emergence of vertically stacked van der Waals (vdW) heterostructures provides new opportunities for these materials to be employed in a wide range of novel applications. Understanding the interlayer coupling in the stacking geometries of the heterostructures and its effect on the resultant material properties is particularly important for obtaining materials with desirable properties. Here, we report that the atomic bonding between stacked layers and thereby the interlayer properties of the vdW heterostructures can be well tuned by the substrate surface defects using WS2 flakes directly grown on graphene. We show that the defects of graphene have no significant effect on the crystal structure or the quality of the grown WS2 flakes; however, they have a strong influence on the interlayer interactions between stacked layers, thus affecting the layer deformability, thermal stability, and physical and electrical properties. Our experimental and computational investigations also reveal that WS2 flakes grown on graphene defects form covalent bonds with the underlying graphene via W atomic bridges (i.e., formation of larger overlapping hybrid orbitals), enabling these flakes to exhibit different intrinsic properties, such as higher conductivity and improved contact characteristics than heterostructures that have vdW interactions with graphene. This result emphasizes the importance of understanding the interlayer coupling in the stacking geometries and its correlation effect for designing desirable properties.

AB - The one-pot protocol by the dendritic copper powder-mediated Knoevenagel condensation/annelation is delineated here for the synthesis of 3-amido-2 quinolones. It is practical with moisture tolerance and easy setup, and is compatible with many functional groups under mild conditions. This method was applied for the preparation of the key intermediates of biologically relevant 3 amido-2-quinolones.

AB - A three-dimensional hierarchical Ni3Se2 nanorod array (NA) grown in situ on foam Ni is the first to act as a carbon/binder-free electrode of SIBs via a one-step reversible conversion reaction. By a special decomposition-fusion process, the morphology and composition of the NA are regulated to obtain ultrahigh areal capacity, which is three times greater than that reported for other metal selenides. PMID- 30303227 TI - SSZ-70 borosilicate delamination without sonication: effect of framework topology on olefin epoxidation catalysis. AB - We report a scalable delamination procedure for a SSZ-70-framework layered zeolite precursor, which for the first time does not involve either sonication or long-chain surfactants. Our approach instead relies on the mild heating of layered zeolite precursor B-SSZ-70(P) in an aqueous solution containing Zn(NO3)2 and tetrabutylammonium fluoride. Powder X-ray diffraction data are consistent with a loss of long-range order along the z-direction, while 29Si MAS NMR spectroscopy demonstrates preservation of the zeolite framework crystallinity during delamination. The resulting delaminated material, DZ-2, possesses 1.4-fold higher external surface area relative to the nondelaminated three-dimensional zeolite B-SSZ-70, based on N2 physisorption data at 77 K. DZ-2 was functionalized with cationic Ti heteroatoms to synthesize Ti-DZ-2 via exchange with framework B. Ti-DZ-2 contains isolated titanium centers in its crystalline framework, as shown by UV-Vis spectroscopy. The generality of the synthetic delamination approach and catalyst synthesis is demonstrated with the synthesis of delaminated material DZ 3, which is derived from layered zeolite precursor ERB-1(P) with MWW framework topology. Upon catalytic testing for the epoxidation of 1-octene with ethylbenzene hydroperoxide as oxidant, under harsh tail-end conditions that deactivate amorphous Ti-silica-based catalysts, Ti-DZ-2 exhibits the highest per Ti-site activity, selectivity, and stability for 1-octene epoxidation of all catalysts investigated. This testing includes the prior benchmark delaminated zeolite catalyst in this area, Ti-UCB-4, which possesses similar external surface area to Ti-DZ-2 but requires sonication and long-chain surfactants for its synthesis. The synthesis of DZ-2 is the first example of an economical delamination of layered zeolite precursor SSZ-70(P) and opens up new doors to the development of delaminated zeolites as commercial catalysts.

AB - In this report, we have described a FeCl3-catalyzed process involving intramolecular annulation of o-phenoxy diarylacetylenes via hydroarylation to afford a series of biologically potent fused seven-membered (6-7-6) ring compounds under mild reaction conditions. This reaction was believed to proceed through Friedel-Crafts type sequential carbometallation followed by protonation to produce phenyldibenz[b,f]oxepines. This method was also extended to synthesize seven-membered rings that are fused with coumarins. PMID- 30303229 TI - Total synthesis, structural revision and biological evaluation of gamma-elemene type sesquiterpenes. AB - Total synthesis and absolute configuration confirmation of gamma-elemene-type sesquiterpenes, which possess vast potential for biological activities, was investigated based on a convergent synthetic strategy. A key intermediate with all functional groups of this family of natural products was accessed by an intermolecular aldol reaction and then an acetylation of a known ketone (12) derived from commercially available verbenone. The versatile intermediate can be easily transformed into structurally different gamma-elemene-type sesquiterpenes based on control of base-promoted cyclization manipulation in different solvents. The utility of this robust approach is illustrated by the first syntheses of elema-1,3,7(11),8-tetraen-8,12-lactam (4') and 8beta-methoxy-isogermafurenolide (6a), as well as the syntheses of elem-1,3,7,8-tetraen-8,12-olide (3) and hydroxyisogermafurenolide (5) in only 6 or 7 steps. In addition, the structure of the reported 5betaH-elem-1,3,7,8-tetraen-8,12-olide (1) was revised as elem 1,3,7,8-tetraen-8,12-olide (3) by comparison of their identified datum, and the absolute configuration of elema-1,3,7(11),8-tetraen-8,12-lactam was confirmed as 4'. Furthermore, the inhibitory effect of all synthesized natural compounds and their natural analogues on cancer cell proliferation was evaluated. Among them compounds 3, 4 and 4' were found to possess potent inhibitory activity against Kasumi-1 and Pfeiffer. Meanwhile, preliminary structure-activity relationships for these compounds are discussed. PMID- 30303231 TI - pi-Extended hexadeca-substituted cobalt phthalocyanine as an active layer for organic field-effect transistors. AB - Due to their flexibility and solution applicability, organic field-effect transistors (OFETs) are considered prominent candidates for application in flexible and low-cost devices. A soluble phthalocyaninato cobalt(ii) complex was designed and synthesized based on a hexadeca-substitution pattern by introducing peripheral phenylethynyl groups and non-peripheral n-butoxy groups. The cobalt phthalocyanine derivative was characterized using a wide range of spectroscopic and electrochemical methods, as well as single-crystal X-ray diffraction analysis. An OFET device was fabricated using a spin-coated film of soluble 1,4,8,11,15,18,22,25-octakisbutoxy-2,3,9,10,16,17,23,24-octakis-ethynyl phenyl phthalocyaninato cobalt(ii) with a bottom-gate top-contact device configuration. The transfer and output characteristics were investigated to evaluate the charge carrier mobility. The mechanisms of the leakage current through the gate dielectric were also investigated, which revealed that the dominant leakage current mechanism is Fowler-Nordheim tunneling. PMID- 30303232 TI - Piezo-phototronic mediated enhanced photodetection characteristics of plasmonic Au-g-C3N4/CdS/ZnO based hybrid heterojunctions on a flexible platform. AB - We have studied the piezo-phototronic induced enhancement in the photo-response of CdS/ZnO heterojunctions attached with plasmonic Au nanoparticle loaded 2D graphitic carbon nitride (g-C3N4). The hybrid g-C3N4/CdS/ZnO heterojunction favours the charge carrier separation through the formation of a step-like band alignment. Furthermore, the integration of plasmonic Au loaded g-C3N4 nanosheets on the conventional CdS/ZnO heterojunction facilitates improved visible light absorption properties. The heterojunction device on a flexible platform under the application of a strain (~0.017%) exhibits ~102 times higher photoresponse over the control sample at a constant bias of ~2 V. The variation in the photo response under different bending conditions has been explained in terms of the improved charge transport through the modified energy bands at the interface of ZnO. The improved piezo-phototronic properties originated from the plasmonic properties of Au loaded g-C3N4 and the piezoelectric characteristics of c-axis oriented ZnO films may be used for future flexible photonic devices. PMID- 30303233 TI - Barium-promoted hydrothermal stability of monolithic Cu/BEA catalyst for NH3-SCR. AB - As a promising candidate for NOx elimination from the emission of diesel engines, the enhancement effect of Ba on the hydrothermal stability of cordierite supported CuBa/BEA at 600 degrees C for 48 h was investigated by XRD, NH3-TPD, H2-TPR, XPS, EPR, TEM and in situ DRIFTS. Different properties and amounts of active species are significant factors contributing to the enhanced hydrothermal stability of CuBa/BEA-HT. CuBa/BEA-HT has more Cu2+/Cu+ redox-couples and stronger interactions than Cu/BEA-HT, indicating an excellent redox property of the active species in CuBa/BEA-HT. The better redox property of CuBa/BEA-HT produces more nitrates that easily participate in the NH3-SCR reaction, which enhances the low-temperature activity. Furthermore, as observed from EPR and H2 TPR, the appearance of more isolated Cu2+ species and fewer CuO species also contribute to the higher hydrothermal stability of CuBa/BEA-HT. PMID- 30303234 TI - Regioselective synthesis of isoxazole and 1,2,4-oxadiazole-derived phosphonates via [3 + 2] cycloaddition. AB - The results of the study on reactions of halogenoximes bearing (protected) functional groups or fluorinated substituents with various phosphorus-containing dipolarophiles are described. To control the regioselectivity of the reaction, vinylphosphonates bearing a leaving group (i.e. bromine or dialkylamino group) in the alpha or beta position were used; 3,5- and 3,4-disubstituted isoxazoles were obtained in 47-80% and 63-75% yields, respectively. The reaction was also effective for the parent vinyl phosphonate and cyanophosphonate; in this case, the corresponding isoxazoline- and 1,2,4-oxadiazole-derived phosphonates were isolated in 55-69% and 34-73% yields, respectively. The utility of the products obtained was demonstrated by the preparation of direct conformationally restricted analogues of phosphohistidine. PMID- 30303235 TI - Electrochemical study of specially designed graphene-Fe3O4-polyaniline nanocomposite as a high-performance anode for lithium-ion battery. AB - In this work, an anode material with improved thermal stability, charge capacity, charge capacity retention, energy density, cyclic performance, operation safety, reversible capacity, and rate capability was synthesized for battery applications. The graphene-magnetite-polyaniline (Gr-Fe3O4-PANI) nanocomposites (NCs) are believed to deliver outstanding performance owing to the collective effect of the layered graphene (Gr) and magnetite (Fe3O4) hollow rods (HRs), as well as the better conductivity of polyaniline (PANI). The Gr-Fe3O4-PANI NCs easily enable the insertion and deinsertion of Li+, the passage of ions in the electrode, fast kinetics of Li+, and low volume expansion. Gr-Fe3O4-PANI NC was prepared by polymerizing aniline in the presence of already prepared Fe3O4 HRs, then dispersing in Gr. Fe3O4 HRs were synthesized by a hydrothermal route. Electrochemical properties were investigated by galvanostatic charge-discharge analysis and cyclic voltammetry. A lithium-ion battery (LIB) based on the Gr Fe3O4-PANI exhibited a superior reversible current capacity of 1214 mA h g-1, excellent power capability, low volume expansion, high cycling stability and 99.6% coulombic efficiency over 250 cycles. PMID- 30303237 TI - Dynamic Diels-Alder reactions of maleimide-furan amphiphiles and their fluorescence ON/OFF behaviours. AB - The occurrence of dynamic covalent reactions only requires relatively low activation energy, which allows both the forward and reverse reactions to proceed under mild conditions. Here, we report the design and synthesis of amphiphilic maleimide-furan adducts, where hydrophobic maleimide-based and hydrophilic furan based moieties were connected by reversible dynamic covalent bonds. The Diels Alder addition reactions of maleimide-furan adducts are simple, efficient, clean, and reversible without catalysts and side reactions, and occur under mild conditions. Single crystal X-ray diffraction revealed that the length of the dynamic covalent bonds is 1.56 A, which is longer and weaker than for normal covalent bonds. The cleavage and reformation process of the dynamic covalent bonds was monitored by 1H NMR and fluorescence spectroscopy. 1H NMR spectroscopy revealed that the furan moieties of these new maleimide-furan amphiphiles can be exchanged in mixing systems due to dynamic Diels-Alder reactions; thus, two new maleimide-furan compounds can be transformed into each other. The maleimide-furan amphiphiles displayed reversible fluorescence ON/OFF behaviours and interesting H bonding driven supramolecular assembly.

PMID- 30303240 TI - Realizing enhanced luminescence of silver nanocluster-peptide soft hydrogels by PEI reinforcement. AB - Metal nanoclusters (NCs) are a new type of fluorescent nanomaterial composed of several to several tens of metal ions or atoms with a wide range of applications in the fields of catalysis, optics, and biomedicine. However, fluorescence quenching when existing as individuals in aqueous solutions greatly limits their applications. In this study, six-core Ag(i) NCs (Ag6-NCs) were interacted with peptides (DD-5) in water to form soft hydrogels with the aggregation-induced emission (AIE) of Ag6-NCs. The introduction of polyethyleneimine (PEI) into the Ag6-NCs/DD-5 hydrogel succeeded in further enhancing the fluorescence intensity. This dual-AIE behavior of the Ag6-NCs/DD-5/PEI hydrogels is mainly ascribed to the strong hydrogen bonding among the carboxyl groups of Ag6, those of DD-5 and the amino groups of PEI, which effectively restricted intramolecular vibration of the capping ligands on the Ag6-NCs. Moreover, the addition of PEI can effectively promote the gelation speed of Ag6-NCs/DD-5 and act as a physical cross-linker, leading to an increase of the mechanical strength of the hydrogel. This work opens a new pathway for the fabrication of smart composite materials with multiple functions, which show a variety of applications such as chemical/biosensing and bioimaging.

PMID- 30303244 TI - Cancer patients' experiences with urgent referrals to cancer patient pathways. AB - OBJECTIVE: We aimed to explore whether cancer patients urgently referred to a cancer patient pathway (CPP) (CPP referred) by a general practitioner report experiences of pre-diagnosis cancer care differently than patients not referred to a CPP (non-CPP referred). METHODS: Data were collected from cross-sectional questionnaire surveys among cancer patients and their GPs and linked to National registries. Poisson regression was used to generate adjusted prevalence ratios (PR) to compare reported experiences. RESULTS: The study included 2,256 individuals. CPP referred patients reported more positive overall experiences of the pre-diagnosis phase (p < 0.001). Overall, CPP referred patients were 21% more likely than non-CPP referred patients to report a positive experience after adjustment for case-mix, comorbidity, disposable household income and educational level (PR = 1.21 [95% CI: 1.11-1.30]). The difference decreased to 14% when adjusted for Quality Deviations (PR = 1.14 [95% CI: 1.06-1.23]) and to 11% when adjusted for diagnostic interval (PR = 1.11 [95% CI: 1.02-1.20]). CONCLUSION: Our findings suggest that CPP referred cancer patients have better experiences of pre diagnosis cancer care compared to non-CPP referred patients. A substantial part of the difference could be attributed to shorter diagnostic intervals and/or the absence of quality deviations among CPP patients, which reveals the potential for generally improving cancer patients' experiences by seamless and optimised diagnostic pathways. PMID- 30303245 TI - Antiplasmodial activity and cytotoxicity, isolation of active alkaloids, and dereplication of Xylopia sericea leaves ethanol extract by UPLC-DAD-ESI-MS/MS. AB - OBJECTIVES: To assess the antiplasmodial activity of the ethanol extract of Xylopia sericea leaves, Annonaceae, often associated with antimalarial use and to perform a bioguided isolation of active compounds. METHODS: Dereplication of ethanol extract by the UPLC-DAD-ESI-MS/MS technique allowed the identification of the major constituents, isolation and identification of alkaloids. The antiplasmodial and cytotoxic activity of the extract, fractions and isolated compounds was evaluated against the chloroquine-resistant W2 strain Plasmodium falciparum and HepG2 cells, respectively. KEY FINDINGS: Ethanol extract showed high reduction of parasitemia as well as moderate cytotoxicity (86.5 +/- 3.0% growth inhibition at 50 MUg/ml and CC50 72.1 +/- 5.1 MUg/ml, respectively). A total of eight flavonoids were identified, and two aporphine alkaloids, anonaine and O-methylmoschatoline, were isolated. Anonaine disclosed significant antiplasmodial effect and moderate cytotoxicity (IC50 23.2 +/- 2.7 MUg/ml, CC50 38.3 +/- 2.3 MUg/ml, SI 1.6) while O-methylmoschatoline was not active against P. falciparum and showed a low cytotoxicity (33.5 +/- 1.9% growth inhibition at 50 MUg/ml, CC50 274.4 +/- 0.5 MUg/ml). CONCLUSIONS: Characterization of Xylopia sericea leaves ethanol extract by UPLC-DAD-ESI-MS/MS as well as its antiplasmodial activity and the occurrence of anonaine and O-methylmoschatoline in this Xylopia species are reported by the first time.

AB - We evaluated the influence of the IL8 T-738A (nonidentified rs), IL8 T-353A (rs4073), IL17A G197A (rs2275913), and IL17F T7488C (rs763780) single-nucleotide polymorphisms on leprosy. The AA genotype of IL8 T-353A was observed as a risk factor for multibacillary leprosy, regardless of gender and age-of-onset of disease, considering the recessive model (OR, 3.8; 95% CI, 1.1-13.5; P, 0.023). Furthermore, the AA genotype of IL17A G197A was associated with leprosy type 1 reaction (OR, 2.4; 95% CI, 1.1-5.1; P, 0.026) when compared to the group without reaction, which was adjusted for gender and age-of-onset of disease by the model log additive. These results indicate association of IL8 and IL17A polymorphisms with the progression to multibacillary leprosy and with the type 1 reaction, respectively.

PMID- 30303247 TI - Inferior vena cava assessment can predict contrast-induced nephropathy in patients undergoing cardiac catheterization: A single-center prospective study. AB - BACKGROUND: Contrast-induced nephropathy (CIN) following cardiac catheterization remains a considerable clinic challenge. Volume status is very important in the development of CIN. It can be assessed noninvasively by measuring inferior vena cava (IVC) diameters. The aim of this study was to assess whether IVC can be used for prediction of CIN in patient undergoing cardiac catheterization. METHODS: A total of 269 patients undergoing cardiac catheterization were prospectively enrolled in this study. IVC inspiratory and expiratory diameters were measured by transthoracic echocardiography. Caval index was calculated as the percentage decrease in the IVC diameter during respiration. CIN was defined as a >=0.5 mg/dL and/or a >=25% increase in serum creatinine within 72 hour post-procedure. RESULTS: Contrast-induced nephropathy developed in 46 (17.1%) patients after cardiac catheterization. Caval index was significantly higher in patients with CIN than in patients without CIN (47% [40-64] vs 35% [26-50], P < 0.001). In addition, the used contrast volume (145 [90-217] vs 70 [60-100], P < 0.001) and the frequency of percutaneous coronary intervention (50% vs 17.9%, P < 0.001) were significantly higher in patients with CIN than in patients without CIN. In receiver operating characteristic (ROC) curve analysis, caval index >= 41% predicted CIN with a specificity of 69% and sensitivity of 72%. Multivariate analysis indicated that caval index >= 41% was an independent predictor of post procedural CIN development (OR: 3.367, 95% CI: 1.574-7.203, P = 0.002). CONCLUSIONS: Caval index, a simple and noninvasive echocardiographic marker, is an independent predictor of post-procedural CIN development in patients undergoing cardiac catheterization. PMID- 30303249 TI - Nitrous oxide effluxes from plants as a potentially important source to the atmosphere. AB - The global budget for nitrous oxide (N2 O), an important greenhouse gas and probably dominant ozone-depleting substance emitted in the 21st century, is far from being fully understood. Cycling of N2 O in terrestrial ecosystems has traditionally exclusively focused on gas exchange between the soil surface (nitrification-denitrification processes) and the atmosphere. Terrestrial vegetation has not been considered in the global budget so far, even though plants are known to release N2 O. Here, we report the N2 O emission rates of 32 plant species from 22 different families measured under controlled laboratory conditions. Furthermore, the first isotopocule values (delta15 N, delta18 O and delta15 Nsp ) of N2 O emitted from plants were determined. A robust relationship established between N2 O emission and CO2 respiration rates, which did not alter significantly over a broad range of changing environmental conditions, was used to quantify plant-derived emissions on an ecosystem scale. Stable isotope measurements (delta15 N, delta18 O and delta15 Nsp ) of N2 O emitted by plants clearly show that the dual isotopocule fingerprint of plant-derived N2 O differs from that of currently known microbial or chemical processes. Our work suggests that vegetation is a natural source of N2 O in the environment with a large fraction released by a hitherto unrecognized process. PMID- 30303251 TI - Social relationship coping efficacy: A new construct in understanding social support and close personal relationships in persons with cancer. AB - OBJECTIVE: Social relationship coping efficacy (SRCE) is the confidence to engage in behaviors that can maintain or enhance close social relationships in the context of illness. This study focused on psychometric analyses of the SRCE scale and its role in maintaining or enhancing personal relationships, social support, and quality of life (QOL). METHOD: A mixed diagnosis sample (N = 151) of cancer patients completed a variety of measures: physical debilitation, received emotional and instrumental support, SRCE, and QOL. RESULTS: The SRCE scale is a 10-item, one-factor, internally reliable (alpha = 0.965) measure with strong concurrent validity in relation to measures of social support. SRCE fully mediated the relationship between physical debilitation and both instrumental and emotional received support. SRCE also was directly related to both social/family well-being and psychological distress, and this relationship was also partially mediated by social support. CONCLUSIONS: The results corroborated that SRCE might account for changes in both instrumental and emotional support. Also, the direct and indirect relationship (mediated by social support) of SRCE with both social/family well-being and distress indicated that interventions to increase SRCE with those at risk for social support loss may bolster social support in personal relationships as well as enhance emotional well-being and quality of life.

AB - A laser interference-based method was proposed to measure the deformation response of cell manipulated by optical tweezers. This method was implemented experimentally by integrating a laser illuminating system and optical tweezers with an inverted microscope. Interference fringes generated by the transmitted and reflected lights were recorded by a complementary metal oxide semiconductor camera. From the acquired images, cell height was calculated and cell morphology was constructed. To further validate this method, the morphological analyses of HeLa cells were performed in static state and during detachment process. Subsequently, the dynamic deformation responses of red blood cells were measured during manipulation with optical tweezers. Collectively, this laser interference based method precludes the requirement of complex optical alignment, allows easy integration with optical tweezers, and enables dynamic measurement of cell deformation response by using a conventional inverted microscope. PMID- 30303254 TI - Identification of candidates for PFO closure in the echocardiography laboratory. AB - A patent foramen ovale (PFO) is implicated in several pathologic processes, including that of cryptogenic stroke (cCVA). Recent trials identify "high-risk" PFOs in patients with cCVA as likely to benefit from percutaneous closure. The younger the patient (<60 years old) the more likely a PFO may be attributable to the cCVA. The RoPE Score index helps determine the likelihood that an existing PFO is related to a cCVA. This may help guide the clinician and patient when contemplating percutaneous PFO closure. When evaluating a patient for possible percutaneous closure, one should identify the CVA as a typical ischemic type stroke. In order to "rule-out" other causes of CVA, imaging of the intracranial arteries, cervical, and aortic arch vessels should be performed. Small vessel disease or a lacunar-type infarct should be excluded. To rule out atrial fibrillation, prolonged monitoring should be performed. An index has been developed to determine the probability that a PFO is the causative etiology and calculates the risk of recurrence. This may help guide the clinician and patient in the decision for PFO closure. In addition, one should consider a work-up for a hypercoagulable state. We will obtain an ultrasound of the lower extremities or consider deep pelvic vein thrombosis (prolonged sitting or malignancy). If the closure is to be performed, the Food and Drug Administration (FDA) has approved the Amplatzer PFO Occluder and the GORE Cardioform Septal Occluder for percutaneous closure. These devices are both approved in patients predominately between ages 18 and 60 years with a cCVA due to presumed paradoxical embolism as verified by a neurologist and cardiologist and when other causes of ischemic CVA have been excluded. "High-risk" PFOs appear to achieve the most potential benefit from percutaneous closure.

AB - The industrial applications and prospects of microbial peroxidase are on the upwards trend, thus necessitating the search for sources with high turnaround time. Actinobacterial species have been a major source of peroxidase for the obvious reasons of having robust metabolite expression capabilities. However, other bacteria species have been underexplored for peroxidase production, hence the motivation for the investigation into the peroxidase production potential of Raoultella ornithinolytica OKOH-1 (KX640917). The bacteria expressed optimum specific peroxidase activity of 16.48 +/- 0.89 U mg-1 , which is higher than those previously reported. The optimal fermentation conditions were pH 5 (3.44 +/ 0.64 U mL-1 ), incubation temperature of 35 degrees C (5.25 +/- 0.00 U mL-1 ), and agitation speed of 150 rpm (9.45 +/- 2.57 U mL-1 ), with guaiacol and ammonium chloride as the best inducer and nitrogen supplement, respectively. On valorization of agrowastes as a sole carbon source for the secretion of peroxidase, sawdust gave the best peroxidase yield (15.21 +/- 2.48 U mg-1 ) under solid-state fermentation. Also, a nonperoxide-dependent enzyme activity, which suggests probable laccase activity, was observed. The ability of the bacteria to utilize agrowastes is highly economical and as well a suitable waste management strategy. Consequently, R. ornithinolytica OKOH-1 is a promising industrial strain with dexterity for enhanced peroxidase production. PMID- 30303256 TI - Identification of genetic risk factors of aggressive periodontitis using genomewide association studies in association with those of chronic periodontitis. AB - To identify the genetic risk factors for aggressive periodontitis (AgP), it is important to understand the progression and pathogenesis of AgP. The purpose of this review was to summarize the genetic risk factors for AgP identified through a case-control genomewide association study (GWAS) and replication study. The initial studies to identify novel AgP risk factors were potentially biased because they relied on previous studies. To overcome this kind of issue, an unbiased GWAS strategy was introduced to identify genetic risk factors for various diseases. Currently, three genes glycosyltransferase 6 domain containing 1 (GLT6D1), defensin alpha1 and alpha3 (DEFA1A3), and sialic acid-binding Ig-like lectin 5 (SIGLEC5) that reach the threshold for genomewide significance have been identified as genetic risk factors for AgP through a case-control GWAS.

AIM: to evaluate serum IL-33 in patients with asthma and healthy controls, and to evaluate the association of IL-33 with different asthma phenotypes. METHODS: Patients with asthma (n=115) and healthy subjects (n=85) were included in the study. Subjects with asthma were divided into groups according to their phenotype: allergic/non-allergic, eosinophilic/non eosinophilic, obese/non-obese and severity according to GINA (mild, moderate, severe). The concentration of IL-33 in serum was measured by standardized enzyme linked immunosorbent assay. RESULTS: The level of IL-33 was significantly higher in patients with asthma when compared to healthy subjects (672.73+/-104.47 pg/mL versus 268.52+/-27.56 pg/mL, p<0.05). IL-33 was also higher in the allergic asthma group patients when compared to non-allergic asthmatics (844.61+/-152.08 pg/mL versus 369.56+/-77.94 pg/mL, p<0.05). There was a significantly higher serum IL-33 level in the eosinophilic asthma group when compared to the group of non-eosinophilic asthma patients (1001.10+/-199.11 pg/mL versus 337.49+/-72.68 pg/mL, p<0.01). We did not find a significant difference in serum IL-33 level between different asthma severity groups, obese and non-obese asthmatics. CONCLUSION: IL-33 is increased in asthma patients, particularly in some phenotypes: allergic asthma and eosinophilic asthma. This article is protected by copyright. All rights reserved. PMID- 30303259 TI - On the reconceptualization of Alzheimer's disease. AB - In the hope of future treatments to prevent or slow down the disease, there is a strong movement towards an ever-earlier detection of Alzheimer's disease (AD). In conjunction with scientific developments, this has prompted a reconceptualization of AD, as a slowly progressive pathological process with a long asymptomatic phase. New concepts such as 'preclinical' and 'prodromal' AD have been introduced, raising a number of conceptual and ethical questions. We evaluate whether these new concepts are theoretically defensible, in light of theories of health and disease, and whether they should be understood as disease or as an at risk state. We introduce a pragmatic view on disease concepts and argue that an evaluation of the reconceptualization of AD should also take its aims and effects into account, and assess their ethical acceptability. The reconceptualization of AD is useful to coordinate research into preventive strategies, and may potentially benefit future patients. However, in the short term, early detection and labelling of 'preclinical AD' can potentially harm people. Since there is no treatment available and the predictive value is unclear, it may only create a group of 'patients-in-waiting' who may suffer from anxiety, uncertainty and stigmatization, but will never actually develop dementia. We conclude that only if the promise of preventive medication materializes, will the reconceptualization of AD turn out unequivocally to be for the better. Otherwise, the reconceptualization may do more harm than good. PMID- 30303261 TI - Embryo donation or embryo adoption? Conceptual and normative issues. AB - A central question in the ethical debate on the practice of relinquishing in vitro fertilization surplus embryos for family building is whether we ought to think of it more in terms of donating these embryos or in terms of having them adopted. Deciding between these two alternatives is more than a matter of mere terminology. It has an impact on normative questions, e.g., on the question of what criteria for parent selection ought to be applied to the recipients of the embryos, and on the moral evaluation of the act of 'donating' the embryo or 'having it adopted'. In this article, I defend the view that we should conceptualize the relinquishment of spare embryos according to the adoption model, not as a donation. Section 2 sketches the outline of the argument by making clear how we may ground a defense of the adoption model in a theory of parental responsibility without implicitly elevating the moral status of the embryo. Section 3 contains a preliminary defense of the adoption model that draws on geneticism as what seems to me the most persuasive theory of parental responsibility. In section 4, I examine three objections to geneticism and either rebut them or, insofar as they are justified, try to accommodate them into my view. In section 5, I point out some features that distinguish embryo adoption from the adoption of (born) children. I contend, however, that these differences are compatible with the adoption model. Section 6 is concerned with the normative ramifications of this view. PMID- 30303260 TI - Does an integrated outreach intervention targeting multiple stages of early psychosis improve the identification of individuals at clinical high risk? AB - AIMS: To explore the impact of a targeted case identification intervention, with training and education regarding first-episode psychosis and clinical high-risk syndromes, on the referral and identification of those at high risk. METHODS: Using a historical control design, referral information from pre-intervention and post-intervention periods was collected via administrative data and clinician notes from a catchment-based early psychosis service. RESULTS: A significant increase in the number of referrals sent to the service's clinical high-risk unit was observed following the intervention (P = 0.01). The proportion of referrals eligible was significantly higher post-intervention (P = 0.03), with the majority (26/44, 59.1%) referred via the first-episode psychosis service unit. CONCLUSIONS: An integrated outreach intervention for both first-episode psychosis and the clinical high-risk state was effective in increasing referrals of eligible cases to the service's at-risk unit. Rather than being stage-specific, targeted case identification strategies and service integration should span across the early stages of psychosis. PMID- 30303262 TI - Clients' experience of change: An exploration of the influence of reformulation tools in cognitive analytic therapy. AB - Case formulation is considered important in both the development of the therapeutic relationship and in starting the process of therapeutic change. Cognitive analytic therapy (CAT) describes the developmental origins and maintenance of a client's problems in both written (reformulation letter) and diagrammatic form (sequential diagrammatic reformulation). This study aimed to investigate the effects of these reformulation tools on insight and symptom change. A small-N repeated measures design was employed with quantitative and qualitative measures collected from six therapist/client dyads. Participating therapists kept a record of their delivery of CAT reformulation tools. Participating clients completed the insight subscale of the Self-Reflection and Insight Scale every fourth session and the Clinical Outcomes in Routine Evaluation-10 every session. Qualitative data from client change interviews regarding their experiences of CAT and attributions of change was explored using template analysis. Participants demonstrated improvements (symptom reduction and insight increases) over the course of the intervention. Administration of reformulation tools did not consistently result in significant changes on insight and symptom measures. However, the tools were identified by participants as leading to insight and emotional change within the context of a good therapeutic relationship. These findings suggest that a genuine therapeutic relationship is an important change mechanism operating through, and strengthened by, CAT specific tools. PMID- 30303263 TI - Identification of Duchenne/Becker muscular dystrophy mosaic carriers through a combined DNA/RNA analysis. AB - OBJECTIVE: The Duchenne/Becker muscular dystrophy (DMD) carrier screening includes the evaluation of mutations in DMD gene, and the most widely used analysis is the multiplex ligation-dependent probe amplification (MLPA) for the DMD deletions/duplications detection. The high frequency of de novo mutations permits to estimate a risk up to 20% of mosaicisms for mothers of sporadic DMD children. The purpose of this study is to evaluate alternative analytical strategy for the detection of mosaics carrier women, in order to improve the recurrence risk estimation. METHOD: Different DNA and RNA analyses were conducted on samples from a woman that conceived a DMD fetus without previous family history of dystrophynopathy. RESULTS: Standard MLPA analysis failed to identify mosaicism, even if MLPA doses suggested it. Electrophoresis and direct sequencing conducted on RNA permitted to detect two different amplicons of cDNAs, demonstrating the presence of somatic mosaicism. Subsequent detection of a second affected fetus confirmed the mosaic status on the mother. CONCLUSION: The implementation of RNA analysis in diagnostic algorithm can increase the sensitivity of carrier test for mothers of sporadic affected patients, permitting detection of mosaic status. A revision of analytical guidelines is needed in order to improve the recurrence risk estimation and support prenatal genetic counseling. PMID- 30303264 TI - Autophagy gene ATG5 knockdown upregulates apoptotic cell death during Candida albicans infection in human vaginal epithelial cells. AB - PROBLEM: Candida albicans infection induces damage in host cells that results in the activation of cell death pathways such as apoptosis and necrosis. Autophagy acts as a pro-survival mechanism during various infections and has cross talks with apoptosis. The objective of our study was to delineate the effect of autophagy knockdown in human vaginal epithelial cells (VECs) during Candida infection-induced apoptosis. METHOD OF STUDY: We overexpressed wild-type or mutant form of autophagy-related gene 5 (ATG5) in human VECs and determined the levels of autophagy and lysosome marker genes upon C. albicans infection. We analyzed the expression of apoptosis and necrosis markers using confocal microscopy and flow cytometry. RESULTS: Mutant ATG5 overexpressing VECs were unable to form Atg5-Atg12 complex, which is required for functional autophagy pathway. Upon Candida albicans infection, wild-type ATG5 overexpressing cells showed upregulation of autophagy marker genes, ATG5, LC3-I, LC3-II, and LAMP-1. Mutant ATG5 overexpressing cells could not upregulate LC3-II and LAMP-1 expression, indicating a defective autophagy pathway. Confocal microscopy and flow cytometry results revealed that wild-type ATG5 overexpressing VECs showed significantly lower number of apoptotic and necrotic cells as compared to mutant ATG5 overexpressing cells. CONCLUSION: Vaginal epithelial cells with active autophagy were able to survive the damage caused by C. albicans infection, whereas those with defective autophagy succumbed to the infection. This suggests that autophagy plays a critical role in human VECs survival during C. albicans infection. PMID- 30303265 TI - Negligible impact of birth on renal function and drug metabolism. AB - BACKGROUND: Transition from the intrauterine to the extrauterine environment in neonates is associated with major changes in blood flow and oxygenation with consequent increases in metabolic functions. The additional impact of birth on renal function and drug metabolism above that predicted by postmenstrual age and allometry is uncertain. Increased clearance at birth could reduce analgesic effect attributable to a lowering of plasma concentration. These elimination processes can be described using the clearance concept. METHODS: Data from four publications that investigated the time course of glomerular filtration rate and clearance of paracetamol, morphine and tramadol were reanalyzed. The effect of birth, based on postnatal age, was used in conjunction with a theory-based allometric size scaling and maturation based on postmenstrual age. RESULTS: Postnatal age had a short-term effect on the time course of clearance distinguishable from the well-known slower maturation based on postmenstrual age. While elimination might be relatively reduced by 15%-45% at birth, there is a rapid increase in elimination for 1-3 weeks after birth to be 15% greater than that predicted by postmenstrual age alone. CONCLUSION: Birth is associated with a small increase in clearance in addition to that described by postmenstrual age for common analgesic drugs cleared by glucuronide conjugation (morphine, paracetamol) or by the P450 cytochrome oxidase (tramadol) and renal systems. While the increase is of biological interest, it would not be expected to have any clinically relevant impact on renal function or drug dosing. The processes of maturation described by these models are potentially applicable to any drug elimination process. PMID- 30303267 TI - Osseous involvement in calcific tendinitis: unusual in the usual.

PMID- 30303269 TI - Circulating C1q/TNF-related protein isoform 15 is a marker for the presence of metabolic syndrome. AB - BACKGROUND: C1q/TNF-related protein isoform 15 (CTRP15) has been reported to be related to glucose and lipid metabolism, but the results are inconsistent. Metabolic syndrome (MetS) is a cluster of metabolic disorders. The aim of this study is to determine circulating CTRP15 levels in individuals with MetS and investigate the association among circulating CTRP15 and markers for MetS as well as insulin resistance. METHODS: A total of 341 individuals were recruited for this cross-sectional study. These subjects were screened for MetS. Serum CTRP15 concentrations were measured by ELISA. RESULTS: Serum CTRP15 levels were significantly higher in MetS individuals relative to those of the healthy individuals. Circulating CTRP15 correlated positively with WHR, BMI, SBP, FAT %, 2 h-BG, FIns, 2 h-Ins, TG, FFA, HbA1c, HOMA-IR, and AUCglucose , while negatively with HDL-C and ISI. Multiple linear regression showed that HOMA-IR and HDL-C are independently related factors influencing serum CTRP15 concentrations. In addition, binary logistic regression analysis showed that serum CTRP15 concentrations were significantly related to MetS. When the mean concentrations of circulating CTRP15 in MetS subjects were stratified by the number of components of the MetS, circulating CTRP15 was found to increase progressively with increasing number of the MetS components. Finally, ROC curve analysis showed that the best cutoff values for circulating CTRP15 to predict MetS and insulin resistance were 63.6 and 64.0 MUg/L. CONCLUSIONS: Serum CTRP15 concentrations were associated with the key components of MetS and insulin resistance. PMID- 30303271 TI - Chlorophyllin supplementation modulates hyperglycemia-induced oxidative stress and apoptosis in liver of streptozotocin-administered mice. AB - Chlorophyllin is a water-soluble mixture of sodium-copper salts of chlorophyll with antioxidant and antimutagen properties. In this study, an attempt has been made to evaluate the effect of chlorophyllin on hyperglycemia-induced oxidative stress and apoptosis in liver of streptozotocin (STZ)-administered mice. In STZ induced diabetes, two causative factors for pancreatic beta-cell deaths are DNA alkylation and profound reactive oxygen species (ROS) generation. In this study, chlorophyllin treatment was found to be able to modulate oxidative stress and apoptosis in liver of diabetic mice. Diabetic mice exhibited a significant reduction of ROS, malondialdehyde (MDA), and protein carbonyl levels upon treatment with the chlorophyllin. However, antioxidant enzymes, such as copper zinc superoxide dismutase (CuZnSOD), manganese superoxide dismutase (MnSOD), and catalase (CAT) showed enhanced activity as well as expression in chlorophyllin administered diabetic mice. The hepatoprotective effect of chlorophyllin was confirmed from the decreased activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP). The histological and ultrastructural studies revealed the ability of chlorophyllin to restore morphological and cellular alterations as observed in STZ-induced diabetic mice. The effect of chlorophyllin on apoptosis showed the downregulation of cysteine dependent aspartate-specific protease (caspase) 3 and caspase 9, whereas upregulation of B-cell lymphoma-2 (Bcl-2) protein, and the terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick-end labeling (TUNEL) assay demonstrated a few apoptotic cells. In conclusion, it can be stated that chlorophyllin treatment can exert hepatoprotective effect via modulating hyperglycemia-induced oxidative stress and apoptosis in STZ-administered diabetic mice.

AB - Children from highly disadvantaged families tend to experience worse health, educational, and job outcomes than less disadvantaged peers. However, the mechanisms underlying these relationships remain to be explicated. In particular, few studies have investigated the relationships between the psychosocial influences that children are exposed to early in life and longer term cortisol output. This study aims to contribute to the literature by exploring how disadvantaged young children's experiences of family adversity, and parenting and family functioning, are related to their long-term cortisol levels. A sample of 60 children (26 males, mean = 4.25 years, SD = 1.68) and their mothers (mean = 34.18 years, SD = 7.11) from a low-income population took part in a single assessment. Mothers completed questionnaires on the family environment, parenting practices, and child behaviour. Children provided a hair sample for cortisol assay and anthropometric measures. A parsimonious multivariate regression model (including potential predictors identified by a selection algorithm) was used to investigate the correlates of hair cortisol concentration (HCC) in children. Higher levels of social exclusion, being male, and younger age were each associated with higher HCC. Maternal nurturing and emotion coaching were associated with lower HCC. Findings suggest that chronic stress may underlie relationships between adversity and its long-term effects and that HCC offers a promising method for examining chronic stress in children and evaluating interventions by which it can be ameliorated. PMID- 30303272 TI - Analysis of the technical efficiency of the forms of hospital management based on public-private collaboration of the Madrid Health Service, as compared with traditional management. AB - FUNDAMENTALS: The study aims to carry out a comparative analysis of the technical efficiency of hospital management based on public-private collaboration, as compared with traditional management. Specifically, we compare traditionally managed public hospitals, public hospitals managed by a private finance initiative (PFI), public hospitals managed through a public-private partnership (PPP), and hospitals managed through other forms of management, during the period 2009 to 2014, in the hospitals dependent on the Madrid Health Service (SERMAS). METHODS: The study covers all publicly owned general hospitals under SERMAS, consisting of seven PFI hospitals, three PPP hospitals, 11 traditionally managed public hospitals (with the category of general hospital), and four hospitals managed through other forms of hospital management. The technical efficiency indices of the hospitals were calculated using the data envelopment analysis technique. Subsequently, a sensitivity analysis was performed by bootstrapping and variation of model variables to verify their impact on efficiency. Finally, an analysis of the evolution of efficiency in the analyzed period was carried out using the Malmquist Index. RESULTS: In all the analysis models carried out in the analyzed period, the hospitals managed based on public-private collaboration were more efficient than the hospitals under traditional management. CONCLUSIONS: The greater efficiency of hospitals managed based on public-private collaboration, as compared with traditional management, could be attributed to greater organizational and management flexibility.

PMID- 30303275 TI - Learning from history: How research evidence can inform policies to improve rural and remote medical workforce distribution. AB - OBJECTIVE: This article describes the rationale for, and development of, an evidence-based rural typology as the basis for an incentive scheme to improve medical workforce retention. This case study describes the key factors associated with ensuring that research evidence is translated into rural health policy and program implementation. DESIGN: Case study. SETTING: Rural and remote Australia. RESULTS: The development and implementation of the Modified Monash Model in Australia demonstrates some of the key facilitators of knowledge exchange. These include: sound evidence based on good empirical data and rigorous methodology; transparency to peers and stakeholders; the importance of long-term commitment to rural health research; the credibility of the researcher; multiple modes of communication of results; real world validation and amplification of results; patience and persistence underscored by the commitment of researchers to achieving more equitable outcomes for rural and remote doctors; serendipity in terms of timing; and a governmental culture that values evidence-based outcomes. CONCLUSION: The knowledge exchange process is neither easy nor simple and rarely rapid. It often requires the engagement of communities, professional associations, health care providers, researchers, policy-makers and funders. Implementation of evidence into rural health policies and programs benefits all parties through significant improvements in efficiency, effectiveness and equity. PMID- 30303276 TI - Alliances and evidence: Building the capacity and effectiveness of rural health advocacy in Australia. AB - This article describes two strategies that have strengthened the capacity and effectiveness of rural health advocacy in Australia over the past nearly three decades. The first is the development of the National Rural Health Alliance, an organisation that grew from strategic efforts to develop relationships between rural and remote health practitioners and organisations. The second is the development, organisation and use of data and evidence to highlight rural health needs. There has been important synergy between these two streams of activity, with research and evidence providing the tools and the National Rural Health Alliance providing the strategy and techniques to influence the rural and remote health care agenda.

AB - From the perspective of one rural New Zealand Maori community involved in a health service research study, this article describes 'Te Tomokanga' - an established local Maori model of engagement. This model served as an essential guide for researchers coming into the community and at the same time, enabled the community to take ownership of the research process. This may have applicability to research in rural Indigenous communities elsewhere. PMID- 30303278 TI - Point-of-care ultrasound in rural New Zealand: Safety, quality and impact on patient management. AB - OBJECTIVE: To evaluate the safety, quality and impact of point-of-care ultrasound on patient management when performed by rural generalist doctors. DESIGN: Cross sectional descriptive study. SETTING: Six rural small hospitals serving a range of communities in rural New Zealand. PARTICIPANTS: All generalist doctors practising ultrasound in the study hospitals. MAIN OUTCOME MEASURES: Technical quality, accuracy, impact on diagnostic certainty, patient disposition and overall patient care. RESULT: Participants correctly interpreted 90% of images and a similar percentage of point-of-care ultrasound findings when compared with the results of formal imaging or the final diagnosis. In total, 87% of scans contributed to the diagnostic process, changing the diagnostic probability. There was a 4% overall reduction in the number of patients needing hospital admission or transfer to an urban base hospital. The overall impact on patient care was positive for 71% of point-of-care ultrasound scans. Three percent of scans had the potential for patient harm. CONCLUSION: Rural generalists' practise a broad scope of point-of-care ultrasound that, when used as a part of the full clinical assessment, has a positive impact on patient care, improving diagnostic certainty and reducing the need for hospital admission and inter-hospital transfer. There are challenges in learning and maintaining the skills needed to practise a high standard of point-of-care ultrasound in this context. Further consideration needs to be given to the development safe scopes of practice, training, credentialing and quality assurance.

PMID- 30303279 TI - Osteoporosis and low bone mineral density (osteopenia) in rural and remote Queensland. AB - OBJECTIVE: To report that prevalence rates of osteoporosis and osteopenia differ according to different levels of remoteness in Queensland, Australia. DESIGN: Retrospective analysis of bone mineral density scans undertaken between April 2015 and April 2016. SETTING: Mobile laboratory housing a dual energy X-ray absorptiometry in rural and remote Queensland. PARTICIPANTS: Four-thousand-four hundred-and-twenty-seven referred individuals 70 years of age or older. MAIN OUTCOME MEASURES: Bone mineral density (g cm-2 ) at two sites was used to measure the level of bone health as per the World Health Organization criteria for osteoporosis. RESULTS: A slightly higher percentage of women was screened and the percentage screened in both men and women decreased as levels of remoteness increased. Women in outer regional areas had significantly higher odds of having osteopenia over normal bone mineral density, compared to women in an urban setting. CONCLUSION: As the level of remoteness increased, there was a decrease in the percentage of men and women being screened to determine their risk of osteoporosis. Furthermore, the current data suggest that women in more remote areas have significantly lower bone density, compared to an urban female population. Finally, men and women have similar levels of osteopenia across Queensland, Australia. PMID- 30303281 TI - Framework for examining the spatial equity and sustainability of general practitioner services. AB - OBJECTIVE: To propose a framework for examining both the spatial equity and sustainability of GP services. DESIGN: A conceptual discussion based on a systematic literature review of spatial equity definitions and methods. SETTING: Improving the spatial equity of health services is a key step in achieving health equity. Health systems should contribute to achieving health equity and maintain equitable services into the future. The GP services are a key component of primary health care, which often aims to promote health equity. Despite the importance of spatially equitable and sustainable GP services, a framework for analysis has not yet been established. MAIN OUTCOME MEASURE: Examples of how the proposed framework could be implemented are provided from the New Zealand health care context. RESULT: The framework entails three steps: (i) defining spatial equity and sustainability; (ii) estimating current and future distributions of health services and needs; and (iii) quantifying spatial equity and sustainability. In step (i), a needs-based distribution is the most common definition of spatial equity, while sustainability is the ability to provide ongoing equitable access. Step (ii) depends on current and future estimates of access and need within a well-defined geographical area. In step (iii), spatial equity and sustainability should be quantified through measures, such as the Gini coefficient. Current and future levels of spatial equity should then be compared to assess the sustainability of equitable GP services. CONCLUSION: This article outlines a novel conceptual framework for examining the spatial equitability and sustainability of GP services. PMID- 30303282 TI - Not counting.

AB - Paramedic services in Australia and New Zealand (Australasia) share many characteristics, with both offering versions of the Anglo-American system of emergency medical response. Their industry and professional bodies are transnational and as a result have similar industry standards and professional expectations. The major difference been the two countries is their sources of funding, with Australian paramedic services generally receiving more government funding than those in New Zealand. Both countries provide a range of services that use a mix of volunteer and professional staff and employ state-of-the-art communications and medical technology to provide high-level clinical services. In common with other higher income countries, they face the challenge of rising usage associated with ageing populations. Both countries are adapting to this through broadening their response models, from a focus on emergency medical response to the provision of a mobile health service that will see the emergence of more practitioners paramedic roles. These emerging models challenge the core missions of paramedic services, as well as the professional identity of paramedics. Despite these trends towards higher level and well-integrated paramedic services in Australia and New Zealand, communities and many other health professionals have limited knowledge or understanding of how paramedic services are organised, the characteristics of paramedics and allied staff and limited appreciation of their potential to make greater contributions to the health and well-being of communities. This article provides an introduction to how paramedics, as members of multidisciplinary teams, are well placed to contribute to improvements in health outcomes.

PMID- 30303285 TI - Improving the physical health of people living with mental illness in Australia and New Zealand. AB - People diagnosed with mental illness have relatively poor physical health and die earlier than their counterparts in the general population. People living with mental illness in rural Australia have three times the risk of premature death than the total population. This article reviews recent international, Australian and New Zealand research, identifies the increased risk of early death of people living with mental health issues in rural settings and looks at the need for policy and practice responses. The 'Equally Well' national initiatives are described in Australia and New Zealand, which seek to systematically address this inequity as a matter of priority. Finally, it argues for co-design and consumer participation in policy development, program implementation and research. Improved understanding of the perspectives and priorities of people with experience of mental illness is vital if change is to be fully realised.

PMID- 30303287 TI - Two decades of building capacity in rural health education, training and research in Australia: University Departments of Rural Health and Rural Clinical Schools. AB - This review article reports on the contribution of university Departments of Rural Health and Rural Clinical Schools to the development of rural health and the rural health workforce and is set at the Australian Government's university Departments of Rural Health and Rural Clinical Training and Support Programs. The main outcome measures include educational infrastructure, clinical academic workforce, student numbers, community engagement, research outputs, rural health and workforce outcomes. As a result, university Departments of Rural Health and Rural Clinical Schools have established a substantial geographical footprint covering most of the rural and remote populations and regions across Australia. They have a large distributed rural clinical academic workforce that exceeds 1300. Medical student numbers on long-term placements have increased threefold from inception to 1200 annually. Allied health and nursing numbers doubled over 10 years to 4000 in 2013 and are projected to double again by 2018. In 2013, they published 363 peer-reviewed papers - half of which specifically addressed rural and/or remote health issues. High levels of intention to practise rurally and uptake of rural and remote practice following exposure to rural training have been reported, especially for medicine. Thus, university Departments of Rural Health and Rural Clinical Schools constitute a national network of academic units that deliver academically enriched clinical education and training for medical, nursing and allied health students and fulfil an essential academic role for the health system in rural and remote Australia. Community engagement and accountability to region are hallmarks of the program. Early evidence of the uptake of rural and remote practice following exposure to rural training has set expectations for the Rural Health Multidisciplinary Training Program.

PMID- 30303290 TI - Crystallization-Induced Emission Enhancement of a Deep-Blue Luminescence Material with Tunable Mechano- and Thermochromism. AB - Organic luminescent materials with the ability to reversibly switch the luminescence when subjected to external stimuli have attracted considerable interest in recent years. However, the examples of luminescent materials that exhibit multiresponsive properties are rarely reported. In this work, a new stimuli-responsive dye P1 is designed and synthesized with two identical chromophores of naphthalimide, one at each side of an amidoamine-based spacer. This amide-rich molecule offers many possibilities for forming intra- and intermolecular hydrogen bond interactions. Particularly, P1 has an intrinsic property of cocrystallizing with methanol. Compared with the pristine P1 sample, the as-prepared two-component cocrystalline material displays an exceptive deep blue emission, which is extremely rare among naphthalimide-based molecules in the solid state. Furthermore, the target material exhibits an obvious mechanochromic fluorescent behavior and a large spectral shift under force stimuli. On the other hand, the cocrystalline material shows an unusual "turn off" thermochromic luminescence accompanied by solvent evaporation. Moreover, using external stimuli to reversibly manipulate fluorescent quantum yields is rarely reported to date. The results demonstrate the feasibility of a new design strategy for solid-state luminescence switching materials: the incorporation of solvents into organic compounds by cocrystallization to obtain a crystalline state luminescence system. PMID- 30303291 TI - Controlled Air-Etching Synthesis of Porous-Carbon Nanotube Aerogels with Ultrafast Charging at 1000 A g-1. AB - Supercapacitors are energy storage systems capable of fast charging and discharging, thus generating superior power density. Porous carbon with high surface area and tunable pore size represents a promising candidate to construct ultrafast supercapacitors; so far, most porous carbon-based electrodes can only be charged to a moderate current density (100-200 A g-1), also with significant capacitance loss at increasing rate. Here, it is shown that a 3D aerogel consisting of interconnected 1D porous-carbon nanotubes (PCNs) can serve as a freestanding supercapacitor electrode with excellent rate performance. As a result, the PCN aerogel electrodes achieve 1) ultrafast charging at current densities up to 1000 A g-1 (corresponding to a charge period of 16 ms), which is the highest value among other porous carbon-based supercapacitors, 2) superior cycling stability at high charging rates (88% capacitance retention after 105 cycles at 1000 A g-1). Mechanism study reveals favorable kinetics including a centralized pore size distribution at 0.8 nm which is a dominant factor to allow high-rate charging, a low and linear IR drop, and a metallic feature of 1D PCNs by theoretical calculation. The results indicate that 1D PCNs with controlled porous structures have potential applications in ultrafast energy conversion and storage.

A non-Pt cathode catalyst is now shown to be capable of simultaneously reducing both O2 and H2 O2 , thus rendering H2 O2 a useful part of the feed stream. The applicability of this unique catalyst is demonstrated by employing it in a fuel cell running on H2 /CO and O2 /H2 O2 .

AB - The first biologically relevant clickable probe related to the antitumor marine lipid jaspine B is reported. The concise synthetic route to both enantiomers relied on the supercritical fluid chromatography (SFC) enantiomeric resolution of racemic materials. The eutomeric dextrogyre derivative represents the first jaspine B analogue with enhanced cytotoxicity with IC50 down to 30 nm. These enantiomeric probes revealed a chiralitydependent cytoplasmic imaging of U2OS cancer cells by in situ click labeling. PMID- 30303295 TI - Spectroscopic Evidence for an Attractive Cation-Cation Interaction in Hydroxy Functionalized Ionic Liquids: A Hydrogen-Bonded Chain-like Trimer. AB - We address the formation of hydrogen bonded domains among the cationic constituents of the ionic liquid (IL) 1-(3-hydroxypropyl)pyridinium tetrafluoroborate [HPPy][BF4 ] by means of cryogenic ion vibrational predissociation spectroscopy of cold (ca. 35 K) gas-phase cluster ions and quantum chemistry. Specifically, analysis of the OH stretching bands reveals a chain-like OH???OH???OH???BF4 - binding motif involving the three cations in the cationic quinary cluster ion (HPPy+ )3 (BF4 - )2 . Calculations show that this cooperative H-bond attraction compensates for the repulsive Coulomb forces and results in stable complexes that successfully compete with those in which the OH groups are predominantly attached to the counter anions. Our combined experimental and theoretical approach provides insight into the cooperative effects that lead to the formation of hydrogen bonded domains involving the cationic constituents of ILs. PMID- 30303296 TI - The specificity of monoclonal anti citrulline protein antibodies - reply to Dr Holmdahl's letter. AB - Rikard Holmdahl has commented on our recently published paper on specificity and function of human monoclonal antibodies (mAbs) from synovial plasma cells that react with citrullinated proteins and peptides (1). He also comments on our previous study from 2013 (2) that was based on mAbs generated from synovial B cells. Dr Holmdahl's letter provides us with an opportunity to discuss and clarify some methodological issues concerning RA monoclonal autoantibody expression, specificity, and functionality. In our eyes, cloning and characterization of human monoclonal autoantibodies from patients represents an important approach to the understanding of origins and functions of autoantibodies in the pathogenesis of immune-mediated diseases. In fact, the RA field has been especially active on making use of mAbs derived from the immunoglobulin sequences from patient-derived B cells and plasma cells. This article is protected by copyright.

AB - Estuaries provide an ideal niche to study structure and function of bacterioplankton communities owing to the presence of a multitude of environmental stressors. Bacterioplankton community structures from nine global estuaries were compared to understand their broad-scale biogeographic patterns. Bacterioplankton community structure from four estuaries of Sundarbans, namely Mooriganga, Thakuran, Matla, and Harinbhanga, was elucidated using Illumina sequencing. Bacterioplankton communities from these estuaries were compared against available bacterioplankton sequence data from Columbia, Delaware, Jiulong, Pearl, and Hangzhou estuaries. All nine estuaries were dominated by Proteobacteria. Other abundant phyla included Bacteroidetes, Firmicutes, Acidobacteria, Actinobacteria, Cyanobacteria, Planctomycetes, and Verrucomicrobia. The abundant bacterial phyla showed a ubiquitous presence across the estuaries. At class level, the overwhelming abundance of Gammaproteobacteria in the estuaries of Sundarbans and Columbia estuary clearly stood out amidst high abundance of Alphaproteobacteria observed in the other estuaries. Abundant bacterial families including Rhodobacteriaceae, Shingomonadaceae, Acidobacteriaceae, Vibrionaceae, and Xanthomondaceae also showed ubiquitous presence in the studied estuaries. However, rare taxa including Chloroflexi, Tenericutes, Nitrospirae, and Deinococcus-Thermus showed clear site-specific distribution patterns. Such distribution patterns were also reinstated by nMDS ordination plots. Such clustering patterns could hint toward the potential role of environmental parameters and substrate specificity which could result in distinct bacterioplankton communities at specific sites. The ubiquitous presence of abundant bacterioplankton groups along with their strong correlation with surface water temperature and dissolved nutrient concentrations indicates the role of such environmental parameters in shaping bacterioplankton community structure in estuaries. Overall, studies on biogeographic patters of bacterioplankton communities can provide interesting insights into ecosystem functioning and health of global estuaries.

AB - BACKGROUND: Glucagon-like peptide-1 (GLP-1) receptor (GLP-1R) agonists modulate gastrointestinal motility; however, the effects of GLP-1R agonists on colonic motility are still controversial, and the molecular mechanism is unclear. Exendin 4 shares 53% homology with GLP-1 and is a full agonist of GLP-1R. In this study, our aims were to explore the role and mechanism of exendin-4 in isolated rat colonic tissues and cells. METHODS: An organ bath system was used to examine the spontaneous contractions of smooth muscle strips. The whole-cell patch-clamp technique was used to investigate the currents of L-type voltage-dependent calcium channels and large conductance Ca2+ -activated K+ (BKCa ) channels in smooth muscle cells. KEY RESULTS: Exendin-4 decreased both the amplitude and frequency of spontaneous contractions of smooth muscle strips in a concentration dependent manner. The inhibitory effect was completely blocked by exendin-4(9 39), a GLP-1R antagonist. Moreover, this effect was partially abolished by tetrodotoxin (TTX), a blocker of neuronal voltage-dependent Na+ channels, Nomega Nitro-l-arginine (L-NNA), a nitric oxide synthase (NOS) inhibitor, apamin, an inhibitor of small-conductance Ca2+ -activated K+ (SK) channels. Whole-cell patch clamp recordings revealed that exendin-4 inhibited the peak current of L-type calcium channels in colonic smooth muscle cells, but did not change the shape of the current-voltage (I-V) curves. The steady-state activation and steady-state inactivation of L-type calcium channels were not affected. Likewise, BKCa currents were significantly inhibited by exendin-4. CONCLUSIONS: Exendin-4 indirectly inhibits colonic muscle activity via a nitrergic and a purinergic neural pathway through NO and ATP release and inhibits L-type voltage-dependent calcium channels and BKCa channels in smooth muscle cells. PMID- 30303299 TI - Employees' and line managers' active involvement in participatory organizational interventions: Examining direct, reversed, and reciprocal effects on well-being. AB - This study examined how employee participation and perceptions of line managers' support during a participatory organizational intervention were related to well being over time. Although previous studies suggest that employees' and managers' active involvement in participatory organizational interventions may be related to well-being, little is known about the temporal aspects, such as at which time during the intervention these factors matter, or possible reciprocal effects. Building on conservation of resources theory, we tested hypotheses concerning direct, reversed, and reciprocal relationships between employee participation and perceptions of line manager support in relation to well-being. We used a four wave panel design consisting of 159 hospital workers. Cross-lagged analyses showed that perceived line managers' support in the initiation and active phase was related to participation in the active phase. Participation in the initiation and active phase was related to well-being in the active and sustained phase, respectively. Results also revealed that participation in the initiation phase was related to perceived line managers' support in the active phase, which in turn predicted participation in the active phase, which translated into job satisfaction in the sustained phase supporting reversed and reciprocal effects in the form of resource caravans. Theoretical implications for research and practice are discussed. PMID- 30303300 TI - The specificity of monoclonal anti-citrulline protein antibodies.

PMID- 30303301 TI - Experience with gluteal V-Y fasciocutaneous advancement flaps in vulvar reconstruction after oncological resection and a modification to the marking: Playing with tension lines. AB - Many post-vulvectomy vulvar reconstruction solutions, using local fasciocutaneous flaps where possible, have been proposed. We report the use of V-Y advancement flaps from the gluteal fold in medium to large vulvar reconstructions and a simple modification we made to the technique in order to minimise wound-related complications. Between 2006 and 2016, 30 vulvar reconstructions were performed via a total of 59 flaps, 24 of which were raised using the proposed modification to the plasty design. Short- and long-term (24 months) follow-up data were analysed, postoperative flap sensitivity was tested, and any arising complications were recorded. The mean age of patients treated was 75.3 years (51 92 years). The mean monolateral defect dimensions were 7.5 * 4.7 * 2.8 cm. Minor complications were recorded in 23% of patients (14% of flaps). One case of ostial stenosis occurred. Micturition and ambulation recovery was rapid, and flap sensitivity was fully restored 24 months after reconstruction. Scars were well hidden by natural soft tissue folds. The outcomes in this case series confirm that the gluteal V-Y advancement fasciocutaneous flap is a useful and simple technique for reconstructing even large vulvar defects. It has a low functional and aesthetic impact and enables rapid return to autonomy. Moreover, the simple modification to the V-Y flap proposed, designed to reduce tension at the apical part of the wound, appears to reduce the complication rate.

AB - AIM: Depression is common in young people, and there is a need for safe, effective treatments. This study examined the efficacy of repetitive transcranial magnetic stimulation in a sample of young people aged 17 to 25 years. METHODS: This retrospective study included 15 people aged 17 to 25 years referred by their private psychiatrists affiliated with Ramsay Health Care, South Australia Mental Health Services. All patients met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for treatment-resistant Major Depressive Disorder. Eleven patients received right unilateral treatment and four patients received bilateral treatment. Patients were assessed at baseline and after treatment. RESULTS: There was a significant improvement on the Hamilton Rating Scale for Depression (t(14) = 4.71, P < 0.0001); Montgomery-Asperg Depression Rating Scale (t(14) = 3.96, P < 0.01) and the Zung Self-Rating Depression Scale (t(14) = 4.13, P < 0.01). There was no difference in response by gender or age. The response rates in these young people did not differ significantly from those of adults aged 25 to 82 years. CONCLUSION: This open label, naturalistic study suggests that repetitive transcranial magnetic stimulation is an effective treatment in young adults who have treatment-resistant depression. Randomized sham-controlled studies are needed to further investigate the efficacy of this treatment in this age group. PMID- 30303309 TI - Divergent Dynamic Kinetic Resolution of a Racemic Mixture of Four Stereoisomers via N-Heterocyclic Carbene Organocatalysis. AB - Racemic mixtures of four stereoisomers are easily formed via many fundamental organic transformations, but the direct utilities of these mixtures have been less studied and remain large challenges to date. In this work, we introduce a new method, i.e., divergent dynamic kinetic resolution, to achieve the separation of racemic mixtures of four stereoisomers. The hypothesis was proved by using a N heterocyclic carbene-catalyzed benzoin reaction, which afforded two separable diastereomeric products bearing three consecutive stereocenters with good to excellent enantioselectivties. We believe that this resolution protocol will find applications in more transformations. PMID- 30303310 TI - An inexpensive method of negative pressure wound therapy for extremities. AB - Negative pressure wound therapy (NPWT) is an established method for the faster wound healing of chronic non-healing wounds. It is also used for laparostomy wounds and healing of split skin grafts. The commercially available machine and the consumables for NPWT are very expensive and economically not feasible in developing and underdeveloped countries. So, we devised a NPWT system for wounds of the extremity using inexpensive, readily available materials in any hospital. The materials used are sterile glove, autoclaved sponge, Foley catheter, and a wall suction unit. The sponge was placed over the wound, and a sterile glove was pulled over it. A Foley catheter was placed over the sponge and taken out through one of the fingers of the glove. Adhesive plaster was used to air-seal the glove. The Foley catheter was fixed with silk ties and connected to wall suction. Granulation and wound healing was faster in this system. This system was safe and inexpensive for the treatment of wounds of the extremity. PMID- 30303311 TI - The impact of sitagliptin, inhibitor of dipeptidyl peptidase-4 (DPP-4), on the ADMA-DDAH-NO pathway in ischemic and reperfused rat livers. AB - BACKGROUND: A correlation between the level of asymmetric dimethylarginine (ADMA) - the inhibitor of the nitric oxide (NO) synthesis - and the liver function and survival after a liver transplantation has been reported. OBJECTIVES: The aim of this study was to evaluate the effect of sitagliptin -the inhibitor of dipeptidyl peptidase-4 (DPP-4) - on the NO-ADMA-dimethylarginine dimethylaminohydrolase (DDAH) pathway in rat livers subjected to ischemia/reperfusion (IR). MATERIAL AND METHODS: The rats received sitagliptin (5 mg/kg, per os - p.o.) (groups: S - livers not subjected to IR procedure, and SIR - livers subjected to IR procedure) or a saline solution (groups: C - livers not subjected to IR procedure, and CIR - livers subjected to IR procedure) for 14 days; following this, livers in the SIR and CIR groups were subjected to ischemia (60 min) and reperfusion (24 h). Aminotransferases were measured before the surgery; additionally, the arginine (ARG), ADMA and symmetric dimethylarginine (SDMA) levels were estimated just before ischemia and during reperfusion (at 0.5, 4 and 24 h). After IR, citrulline, the DDAH activity, mRNA for type 1 DDAH (DDAH1), and arginine methyltransferase type 1 (PRMT1) were determined. RESULTS: The increase in the initial level of ARG/ADMA0 (A/A) ratio in group S compared to group C verged on statistical significance. At 0.5 and 4 h of reperfusion, the highest concentration of ADMA was found in group CIR. At those time points, the ARG level and the A/A ratio were decreased in groups CIR and SIR as compared to groups C and S, respectively. The alanine transaminase (ALT) activity was lower in the sitagliptin-treated group than in the non-treated one. The DDAH and citrulline levels were reduced in group CIR as compared to group C, but were greater in group SIR as compared to group S. The PRMT1 mRNA expression was higher in groups CIR and SIR, compared to groups C and S, respectively. CONCLUSIONS: The increased A/A ratio suggests a protective effect of sitagliptin on livers not subjected to IR. Changes in the DDAH activity and the PRMT1 mRNA expression also imply the protective activity of sitagliptin during IR. PMID- 30303312 TI - Effects of puerarin on spatial learning and memory function in mice with acute alcohol consumption: An evaluation based upon firing rate and oxygen saturation analysis. AB - BACKGROUND: Ethanol is associated with various medical comorbidities affecting the brain and central nervous system. OBJECTIVES: The use of puerarin in treating alcohol-induced memory disorders is systematically evaluated in this study based upon an analysis of the firing rate and oxygen saturation (SO2). MATERIAL AND METHODS: A multi-channel data acquisition system and near-infrared spectroscopy (NIRS) were combined to obtain the electroneurophysiological signals and SO2 in the hippocampus of mice from the Institute of Cancer Research (ICR) after ethanol injection. A T-maze test was performed to study the alteration of spatial memory function. Ethanol was administered intraperitoneally (i.p.) in 2 dosages (1.5 g/kg and 0.5 g/kg). To investigate the effects of puerarin against acute ethanol induced memory impairment, the same parameters corresponding to electroneurophysiological signals, SO2 and behavior performance in mice were also recorded upon the supplementation of puerarin in 2 dosages (25 mg/kg and 50 mg/kg). RESULTS: An inhibited firing rate and decreased SO2 were found in mice treated with an ethanol dose of 1.5 g/kg, which resulted in a low correct choice rate in the T-maze test, while an opposite trend appeared in mice which had been administered a moderate ethanol dose (0.5 g/kg). The trend of SO2 was positively correlated with that of the firing rate. A decreased firing rate and SO2 were accompanied by a decrease in the correct choice rate. With the supplementation of puerarin, a significant increase in the mean firing rate and SO2, as well as an improved correct choice rate, can be found in mice injected with excessive ethanol. CONCLUSIONS: The electroneurophysiological signals and NIRS were combined for the first time to prove that an excessive intake of ethanol can inhibit the spatial learning and memory function of mice. The supplementation of puerarin can suppress these adverse effects induced by ethanol at a high dosage, as evidenced by the increased firing rate and SO2.

AB - Meniere's disease is characterized by episodic vertigo associated with fluctuating hearing loss, tinnitus and fullness of the ear on the affected side. Endolymphatic space enlargement - or endolymphatic hydrops (EH) - is a histological hallmark of the disease that does not explain all its clinical manifestations. Magnetic resonance imaging improvements now allow in vivo visualization of inner ear liquid spaces and appreciation of potential EH. This article discusses these advances and their potential diagnostic implications in the context of Meniere's disease and more generally in cochleovestibular disorders. PMID- 30303324 TI - [Spontaneous involution of Vestibular Schwannomas]. AB - The majority of vestibular schwannomas have a stable evolution or a progression of size. Some publications report cases of spontaneous involution. We report here the clinical and radiological characteristics of this type of tumor observed in 14 patients showing a spontaneous tumor involution of their vestibular schwannoma. The results showed an incidence of 8 % with an average tumor regression of 50 %. Functionally, a hearing loss was found in all patients, without correlation with the duration of the observational follow-up. There are spontaneously involutive vestibular schwannomas, but tumor regression does not prevent the deterioration of hearing. Patients should be considered as a subset of those receiving observational management.

As none of classical causes existed in this patient, we hypothethized that the phenomenon is related to the particular dysfunction of his right inner ear associating a canalar deficit with a preserved otolithic function. In such a situation, the vestibular inputs are slower than normal. Therefore, palinopsia could result from an abnormal temporal integration of visual and vestibular informations.

Medical management including treatment options can be proposed to the patients. For this reason, a correct diagnosis is important. Olfactory testing is one of the cornerstones for the diagnosis of smell impairment which helps to quantify the deficit. Despite good and widespread psychophysical olfactory tests, there are still many challenges in testing olfaction. Most of the current available test may not fully account for some cultural and genetic biases. Therefore it is difficult to develop olfactory tests and standardize them across different populations. In this paper we discuss an alternative method based on " white smells " which may help to overcome these issues.

CPAP is currently the treatment of choice for severe OSAS, but there are mild to moderate cases of OSAS with poor compliance or intolerance to CPAP, for which alternative treatments should be considered. In this article, we present a tool for evaluation of the upper airways, the DISE (Drug-induced sleep endoscopy), the OAM (mandibular advancement device), the bimaxillary advancement osteotomy, the hypoglossal nerve stimulation and the positional treatment.

AB - 80 % of patients suffering from amyotrophic lateral sclerosis present bulbar involvement and 50 % have salivary symptoms, which are often poorly managed. They present either with drooling or thick secretions. This elevates the risk of bronchoaspiration leading to pneumonia, second cause of death in this population. It is hence paramount to treat, while enhancing the patient's quality of life. The first line of treatment is a salivary drying agent such as an atropine-based medication. These treatments have a low adverse effect rate, are reversible and easy to dose. Management of thick secretions is possible with mucolytics. Taking into account the severity of the bulbar involvement, the second line of treatment, once controversial, is salivary gland injections of botulinium toxin. PMID- 30303330 TI - ?

They are more at risk of suicide, discrimination, depression. Today, we better understand that the main causal factor linked with negative experiences is to be found in direct and indirect discriminations, subsequently causing personal and relational difficulties. When transgender youth are fully accepted and supported in their desired gender, they do not significantly differ from other youth. We need to build informed and respectful practices.

The scheme of the five best-known activity of isoenzymes of cytochrome P450 is shown. PMID- 30303337 TI - [ANEMIA OF CHRONIC DISEASES AS A SYSTEMIC MANIFESTATION OF CHRONIC PULMONARY OBSTRUCTIVE DISEASE]. AB - Anemia of chronic disease (ACD) is one of the most frequent forms of anemia is often observed in patients with infections, cancer and chronic inflammatory or autoimmune diseases. The underlying mechanisms are complex and include dysregulation of iron homeostasis and erythropoietin production, impaired proliferation of erythroid progenitor cells and reduced life span of red blood cells. Moreover, ACD is often superimposed by malnutrition, bleeding and renal failure. ACD is mediated through inflammatory cytokines and characterized by low serum iron (hypoferremia) and often increased reticuloendothelial stores of iron. ACD is usually normocytic, normochromic anemia, but it can become microcytic and hypochromic as the disease progresses. Hepcidin, the main regulator of iron homeostasis and its synthesis, is inhibited by iron deficiency and stimulated by inflammation. In many patients the disease is associated with several extrapulmonary manifestations regarded as the expression of the systemic inflammatory state of chronic obstructive pulmonary disease (COPD). Recent studies showed that anemia in patients with COPD is more frequent than expected, with its prevalence ranging from 8 to 33%. Systemic inflammation may be an important pathogenic factor, but anemia in COPD can also be the result of a number of factors, such as the treatment with certain drugs (angiotensin converting enzyme inhibitors or theophylline), endocrine disorders, acute exacerbations and oxygen therapy. Anemia in COPD patients is strongly associated with increased functional dyspnea, decreased exercise capacity and is an independent predictor of mortality. Treatment options to correct anemia used in other chronic diseases, such as congestive heart failure, cancer or chronic kidney disease have not been explored in COPD (i.e. erythropoietic agents, iron supplements or combined therapy). It is not known whether treating the underlying inflammation could improve hematological characteristics. It is important to develop basic diagnostic modalities for this group of patients and formulate methods of anemia correction. PMID- 30303338 TI - [DIAGNOSTIC SIGNIFICANCE OF PLASMA TROPONIN AND CARDIOMYOCYTE FATTY ACID-BINDING PROTEIN LEVELS IN ACUTE CORONARY SYNDROME]. AB - Blood serum content of fatty acid-binding (FABP) protein increases within 2-3 h after the onset of acute coronary syndrome and myocardial infarction (MI) and reaches the maximum 8.5 h after the initiation of cardiomyocyte death. FABP content considerably decreases by the end of at 24-h period due to excretion with urine, remaining elevated for subsequent 24 h. High clinical sensitivity and relatively high organ specificity are typical of FABP for 12 h after ACS. Within the early period of MI clinical specificity of FABP prevails over troponin in terms of concentration. Troponins display higher clinical sensitivity and diagnostic specificity during a 12-h period after ACS, prevailing for several days after MI. Simultaneous measuring of FABP and troponins (Tr) within the first 12 h increases the sensitivity of biochemical diagnostics by 30%. At later periods, simultaneous determination of FABP and Tr becomes unnecessary: FABP is excreted with urine and Tr level acquires predominant diagnostic significance. No relationship has been revealed between blood content of FABP and reperfusion according to electrocardiography data, probably due to rare measurements of this highly dynamic parameter. FABP test cannot be used in patients with circulatory disorders since its results are not adequate. The best option for differential diagnostics of ACS within the first 24 h would be a combined express immunochromatographic test which allows to measure blood FABP and Tr levels pending objective evaluation. PMID- 30303339 TI - [DESIALATED LOW DENSITY LIPOPROTEINS IN HUMAN BLOOD]. AB - The present article is a review of literature on circulating low-density lipoproteins (LDLP) which can induce accumulation of lipids (mainly, cholesterol), in a SMA(+) cell culture of normal human aortic intima. An attempt was undertaken to resolve the paradox of the absence of both native LDLP influence on intracellular lipid accumulation and modifications of in vitro obtained LDLP in the blood-vascular system. It was showed that atherogenic LDLPs are characterized by a number of changes in carbon, protein and lipid components which can be regarded as multiple modifications of LDLP taking place in human blood plasma. Multiply modified circulating LDLP possess of capacity to interact with various cell membrane receptors differing from B and E receptor, and with proteoglycans. Marked absorption of desiliated LDLPs by the cells simultaneous with a decrease in the degradation of apolipoproteins and cholesterol esters as well as induction of peresterification of free cholesterol leads to intracellular accumulation of esterified cholesterol. Formation of large LDLP-containing complexes especially circulating low-density lipoproteins can stimulate accumulation of lipids by smooth muscle cells of intima. Desiliated LDLPs stimulated cell proliferation and connective tissue matrix synthesis despite cholesterol ester accumulation. In conclusion, the authors of this article found and characterized natural multiply modified LDLPs that can be responsible for the symptoms of atherosclerosis at the cellular level. PMID- 30303340 TI - Challenges and future developments in liver transplantation. AB - Liver transplantation (LT) has become the treatment of choice for a wide range of liver diseases in both adult and pediatric patients. Until recently, the largest proportion of LT in adults, were performed in patients with hepatitis C (HCV) related cirrhosis. The recent availability of safe and effective direct antiviral agents to cure HCV infection in almost all patients whatever the HCV genotype and severity of liver disease, will reduce the need for LT in this category of recipients. Thus, it is presumed that in the next 1 to 2 decades HCV related liver disease will diminish substantially, whereas non-alcoholic steato-hepatitis (NASH) will correspondingly escalate as an indication for LT. The greatest challenges facing LT remain the limited supply of donor organs, and the need for chronic immunosuppression, which represent the true obstacles to the greater application and durable success of the LT procedure. This review aims to highlight, in different sections, the main open issues and future developments in LT. These will be focused to explore current and future strategies to maximize the use of limited organs, to offer an update on potential new approaches to immunosuppression and to imagine new indications for LT when the number of patients awaiting transplants for HCV related liver disease is reduced.

AB - Despite the introduction of anti-inflammatory drugs that selectively inhibit cyclo-oxygenase-2 (COX-2), and potent inhibitors of gastric acid secretion, the gastrointestinal adverse effects of non-steroidal anti-inflammatory drugs (NSAIDs) remain a significant clinical problem. Combined use of antisecretory drugs and COX-2 inhibitors is helpful to limit the damage in the proximal gastrointestinal tract (stomach and duodenum), but it increases the risk of injury of small intestine and colon. It was proven that proton pump inhibitors and H2 receptor antagonists significantly worsen NSAID-induced small intestinal damage and microbiota balance. Nowadays, there is no proven effective preventative or curative treatment for NSAID-induced enteropathy. The new strategy of gastrointestinal protection is based on the discovery of endogenous cytoprotective molecules such as hydrogen sulfide (H2S). H2S is a gaseous mediator that produces strong cytoprotective and antioxidant effect on the gastrointestinal tract. The role of H2S in promoting mucosal integrity, healing of tissue injury and resolution of inflammation has been well documented. In addition, H2S stimulates productions of other cytoprotective molecules including prostaglandins, carbon monoxide and nitric oxide. Nowadays, the new generation of H2S-releasing non-steroidal anti-inflammatory drugs is developed and tested in clinical trials. H2S-NSAIDs possess enhanced anti-inflammatory activity and high gastrointestinal safety. PMID- 30303342 TI - [CHARACTERISTICS OF BONE MINERAL DENSITY IN ELDERLY PATIENTS WITH DIABETES MELLITUS].

PMID- 30303343 TI - Transcatheter aortic valve implantation without prior balloon valvuloplasty is associated with less pronounced markers of myocardial injury. AB - BACKGROUND: Aortic valve stenosis is the most common valvulopathy in developed countries. Transcatheter aortic valve implantation (TAVI) is a therapeutic alternative in symptomatic patients at high or prohibitive perioperative risk. Predilatation by balloon aortic valvuloplasty (BAV) under rapid ventricular pacing (RVP) has been a routine part of TAVI. However, both RVP and BAV carry substantial risks and an increasing number of interventional centers are performing TAVI without predilatation (direct TAVI). A transient decrease of left ventricular function and elevated markers of myocardial injury after TAVI with predilatation were observed in previous studies. In this study, we investigated whether direct TAVI was associated with a similar increase in cardiac biomarkers and decrease in ejection fraction in a cohort of our patients. METHODS: Consecutive patients undergoing TAVI without predilatation using a self-expanding system at a single-center between April 2013 and December 2015 were followed up for one year and were retrospectively analyzed regarding mortality, safety and efficacy endpoints as well as common laboratory and echocardiographic parameters. RESULTS: A total of 164 patients (83+/-6 years; 56% female) were included in the analysis. According to the Valve Academic Research Consortium 2 (VARC-2) criteria the technical success rate was 96.3% and 89.1% of patients remained free of a combined safety endpoint at 30 days. Mortality rates at 30 days and 1 year were 3.0% (n= 5) and 10.4% (n= 17), respectively. TAVI without predilatation was highly effective in lowering aortic valve peak velocity from 4.4 +/-0.6 m/s before to 1.7 +/-0.5 m/s (p <0.01), and mean pressure gradient across the valve from 48.7 +/-15.1 mmHg to 8.3+/-4.5 mmHg (<0.05). Left ventricular function remained unaltered after the intervention (51+/-10% prior to TAVI and 51+/-9% post TAVI), whereas high sensitive troponin T (hs-TnT), a well-established marker for myocardial injury, increased significantly from 26 ng/L (interquartile range = 18.00-44.00) to 119 ng/L (interquartile range = 73.25-166.00, p <0.001) during this time. Notably, an increase in the plasma levels of hs-TnT >15 times the upper limit of normal was associated with mortality both one month and one year after TAVI. CONCLUSIONS: TAVI without predilatation is feasible, safe and effective for aortic valve replacement in symptomatic patients with severe aortic stenosis who are at high perioperative risk. In contrast to a cohort of patients who underwent TAVI with predilatation previously published by another center, our patients did not suffer from transient impairment of left ventricular function. As a marker of myocardial injury, hs-TnT showed a less pronounced increase than reported previously. This might be a marker for a prognostic benefit as hs-TnT has been shown to be a strong predictor of outcome in patients undergoing TAVI. We conclude that direct TAVI is a less invasive option involving less myocardial stress. PMID- 30303345 TI - ?

AB - : The aim of this study was to evaluate the prognostic role of the cytokine profile in patients with ST segment elevation myocardial infarction (STEMI). Materials and methods: In the present paper we studied cytokines IL-6, IL-1beta, IL-10, TNFalpha and CRP in 81 patients with different course of STEMI. Results: In patients with complicated course of STEMI a significant increase in the concentration of IL-6, IL-10, FNOalpha, CRP was recorded on the 1st, 7th and 14th days compared with control group of healthy subjects and a group of patients with uncomplicated STEMI. Concentrations of TNFalpha>35.49 pg/ml, IL-6>33.37 pg/ml, IL 10>34 pg/ml, CRP>10.84 mg/l on day 1 may suggest cardiovascular complications in STEMI patients within 1 year after the onset of the disease. We have not found reliable prognostic levels of IL-1beta, as the concentration of this cytokine remained within the accepted normal range.. Discussion: It is concluded that initially elevated levels of CRP l, TNFalpha, IL-6, IL-10 in the blood make it possible to identify groups of patients with myocardial infarction with ST segment elevation at high risk of cardiovascular events throughout the year.

AB - BACKGROUND: To compare efficacy and safety of segmental and monopolar radiofrequency ablation in the management of lower extremity varicose veins. METHODS: 193 patients were treated with segmental RF ablation (Venefit; 97 subjects) or monopolar RF ablation (EVRF; 96 subjects) for lower extremity varicose veins in 2010-2012. A single extremity of each patient with isolated GSV or SSV insufficiency was enrolled. The differences between the two groups in demographic parameters, disease severity, treated veins, peri- and postoperative complications, and treatment efficacy indicators (VCSS) were evaluated. RESULTS: Recanalisation rate at 5 years was 10.3% in Venefit group and 11.3% in EVFR group (p>.05). Varicose vein recurrence rates were 10.3% and 12.9% in the Venefit and EVFR groups, respectively (p>.05). The VCSS reduction was comparable between the two groups(p<.05). CONCLUSIONS: Venefit and EVRF systems can be considered equivalent in terms of efficacy and safety in the management of lower extremity varicose veins.

AB - Aim: To determine content of mononuclear ells (MNC) in peripheral blood of patients with coronary heart disease (CHD) and factors responsible for their functional state and cytokine production. Materials and methods: Concentration of proteinkinases JNK1/2, ERK1/2, MAPK38, AKT1, JAK2, FAK, AMPK, p70S6K, STAT3, STAT5B and STAT6 was determined in MNC lysate by immune-enzyme assay. Interleukin 1beta, 2, 4 and y-interferon levels were measured in blood sera. Results: In patients with angina of effort and unstable angina, the JNK level was 59,8% and 53,1% higher than the normal one respectively (r=0,013) and (r=0,012). The level of the nuclear transcription factor was 26,9% (r=0,015) and 27,9% (r=0,017), JAK2 31,5% (r=0,022) and 48,6% (r=0,018), STAT3 49,6% (r=0,025) and 55,3% (r=0,02), STAT5B 21,5% (r=0,018) and 30,2% (r=0,011) lower. These changes were associated with a 13,1% (r=0,047) and 51,4% (r=0,019) rise in the STAT6 level, 30,1% (r=0,025) and 79,4% (r=0,003) FAK level, 7,6% (r=0,09) and 15,2% (r=0,039) AKT1 level, 65,3 (r=0,02) and 76,2% (r=0,017) p70S6K level. Conclusion: Results of the study suggest persistent pro-inflammatory activation of whole blood cells in CHD patients due to enhanced levels of IL-1 and IL-2, components of the MAPK/SAPK signal pathway in MNC and decreased STAT3 level determining cell sensitivity to IL-10. The elevated intracellular level of ERK and JNK us responsible for high responsiveness of MNC to pro-inflammatory cytokines. PMID- 30303350 TI - ? PMID- 30303351 TI - ?

AB - Aim: To monitor the hemostatic system during platelet concentrate transfusions using low-frequency piezothromboelastography in patients with coronary bypass surgery given aspirin therapy. Materials and Methods: The study involved 148 patients with coronary bypass surgery, with 76 ones undergoing intraoperative transfusion of platelet concentrate and 72 treated without transfusion. The control group consisted of 20 healthy individuals. In the perioperative period indicators of vascular-platelet, coagulation, anticoagulant and fibrinolytic components of hemostasis were evaluated by low-frequency pezotromboelastography using the ARP-01M "Mednord" hardware and software system (Russia). Results: It was shown that the antiplatelet effect of aspirin in the preoperative period was manifest as inhibition of the initial stage of blood coagulation accompanied by increased thrombin potential, the total gain of anticoagulant and fibrinolytic activity of the blood. Heart-lung bypass was accompanied by structural and chronometric anticoagulation, reduction of anticoagulation and increase of blood fibrinolytic activity. In the postoperative period, structural and chronometric anticoagulation was more pronounced in patients who did not undergo transfusion of platelet concentrate than in the group of patients with transfusion. Donor platelets further increased the blood hemostatic potential by neutralizing the antiplatelet effect of aspirin. Perioperative thrombohemorrhagic complications were absent in both groups. Conclusion: Low-frequency piezothromboelastography provides a tool for real-time monitoring the functional state of hemostasis system. Transfusion of platelet concentrate is not advisable given that the thrombin potential is preserved as confirmed by the results of low-frequency piezothromboelastography. PMID- 30303353 TI - ?

AB - Despite significant progress in our understanding and the development of novel therapies, most patients with multiple myeloma will experience relapse of their disease. Therapy of relapsed myeloma has improved due to the availability of novel agents that are highly active against the disease. However, the selection of therapy can be challenging due to the emergence of toxicities, comorbidities and frailty. In the following we discuss our approach to the treatment of the patient with relapsed myeloma. PMID- 30303356 TI - Pulmonary endoscopy emergencies. AB - In clinical practice, interventional pulmonologist faces several situations which can lead to dramatic consequences especially on ventilation and require immediate intervention. We describe the main pathological conditions where urgent bronchoscopy is crucial because they act through mechanisms such as airway obstruction or alteration of the anatomic integrity of the tracheobronchial tree. We point out the problems resulting from inhalation of foreign bodies, one of the most dramatic respiratory emergencies typical of childhood which needs not only the appropriate endoscopic equipment suitable for the age, but also great experience in the management of the possible related complications. Massive haemoptysis is then discussed in order to help choosing the right endoscope and to clarify the steps requested to face this dramatic event. Lastly, iatrogenic tracheal injuries are described, in spite of their low incidence. The correct endoscopic assessment of the lesions enables to select the proper therapeutic approach in multidisciplinary together with surgeons and anesthetists. Due to its peculiarities, emergency does not allow a classic training so it is difficult to estimate the procedure volume necessary to achieve an adequate endoscopic experience. We think, in this field, it is advisable referring to numbers proposed for elections endoscopic procedures. For these reasons, we consider desirable the use of simulators and clinic case discussions during interventional pulmonologists training. PMID- 30303357 TI - Childhood obesity. AB - Childhood obesity has assumed epidemic proportions and it is currently one of the most prevalent public health problems. The pathophysiology of excess weight gain is complex with interactions between genetic factors, environment and biological factors. In this review, we highlight the epidemiology of childhood obesity and discuss clinical evaluation of a child with obesity. A staged approach to treatment is detailed. We discuss the role of lifestyle modifications, pharmacotherapy and bariatric surgery as treatment strategies. PMID- 30303358 TI - [RESEARCH ON THE LEVEL, COMPONENTS AND THE TYPE OF COOPERATIVITY IN THE PATIENTS WITH ASTHMA]. AB - The patient's cooperativity is the major factor which determines the patient's adherence to doctor's prescriptions and, consequently, the achievement of disease control. We proposed the "Evaluation of the cooperativity in asthma" questionnaire to evaluate the level, components and types of cooperativity in 141 patients with the mixed or atopic form of asthma (94.3 and 5.7%, respectively) at admission to hospital who were aware about their disease. The analysis of investigated parameters depending on the level of patients' awareness of their condition (according to the "Awareness of patients about asthma" test), severity and duration of the disease, presence of alexithymia and social and economic index was done. It was found out that patients with asthma exaggerate the degree of their compliance. The general indices of cooperativity (GIC=58.1+/-7.3%) and understanding of danger (35.8+/-3.3%) in the patients who were aware about their disease were low. Qualitative characteristics of individual cooperativity components in examined patients are presented. Nearly 76% of the patients showed negative cooperativity inversely correlating with the severity of asthma and the duration of the disease. Positive cooperativity appeared to be directly related with the higher educational level, occupation and higher income level of the patients. Generally speaking, low average GIC ratings and low patients' adherence to asthma treatment suggest their low cooperativity. PMID- 30303359 TI - ?

AB - Aim: To study the frequency of respiratory symptoms among the reindeer herders of the Yamal region in the Far North of Russia. We conducted a cross-sectional study of the occurrence of respiratory symptoms among 500 subjects of the tundra Nenets population (28.1% of the adult Nenets population in the district), of which 38.3% were men and 61.7% women (average age 40.1 years). All patients were matched for age and occupation. Medical examination was carried out by a pulmonologist with the use of the GARD questionnaire (WHO, 2004) and spirometry. Spirometry was performed with a SpiroUSB device (UK) according to a unified standard and the criteria of ATS/ERS 2005. The frequency of respiratory symptoms among the tundra population was estimated at 71.8%. Cough with expectoration and dyspnea were found in 22.8% of the respondents. 70.0% of the examined subjects worked in the cold, 33% were exposed to the open flame at home, and 34.4% smoked. Respiratory symptoms developed in 16.3% of those working in the cold and in 37% exposed to open fire. The combination of such complaints as cough and sputum production occurred in smokers twice as frequently as in non-smokers (54.1%) (p<0.01).The combination of such complaints as cough and sputum production was twice as likely note in his those who smoked (54.1% vs 20.2%) (p<0.01). The combination of these problems dyspnea was three times more common in the smokers (23,3%vs 7,3%) (p<0.001). At presence at patients of such a factor as work in the cold and the absence of other only 16.3% of them have respiratory symptoms. When using at home the open flame and the absence of other factors leading up 37.0% of the individuals with symptoms of chronic bronchitis. Cough, sputum and dyspnea are formed only among 26.3% of the smokers face when smoking is the only risk factor. If the surveyed residents of all three negative factors respiratory symptoms met at 62.1%. Disorders of respiratory function according to spirometry were not observed in none of the study participants. Respiratory symptoms developed in 62.1% of the subjects exposed to all three risk factors. External respiration indices remain normal in all he examine subjects. It is concluded that residents of the Far North frequently suffer respiratory symptoms without disorders in the external respiratory function. In most cases they associated with three factors (work in the cold, exposure to open fire at home, and smoking). Compensatory stimulation of lung functions may create additional difficulties for diagnostics of bronchial obstruction. PMID- 30303362 TI - ? PMID- 30303361 TI - ? PMID- 30303363 TI - ?

AB - Aim: To estimate the severity of systemic inflammation in subjects with coronary artery disease (CAD) without bronchopulmonary system comorbidity depending on smoking factor. Materials and methods: The subjects were divided into groups depending on smoking factor. We estimated the following laboratory markers of nonspecific inflammation: interleukine (IL)-12, -1beta, tumour necrosis factor alpha, matrix metalloproteinase-9, C-reactive protein. The examination of lungs respiratory function included spirometry, body plethysmography and assessment of diffusing lung capacity. Results: 29.9% of the subjects with CAD smoked, 40% reported discontinuation of smoking in their histories. Smoking in CAD subjects without the history of bronchopulmonary system comorbidity was associated with a higher level of inflammatory markers (IL-12, IL-1beta, TNF-alpha, MMR-9 and CRP) than in subjects who ceased to smoke and those who have never smoked. No differences in the levels of inflammatory markers were revealed in subjects who had smoked before and never smoked. Conclusion: Smoking is widespread among CAD subjects. It is associated with a higher level of markers of nonspecific inflammation as compared to subjects who have never smoked before or ceased smoking. PMID- 30303365 TI - DNA-Functionalized Porous Fe3O4 Nanoparticles for the Construction of Self Powered miRNA Biosensor with Target Recycling Amplification. AB - Herein, we have developed an ultrasensitive self-powered biosensor for miRNA assay based on biofuel cells. The system is composed of indium tin oxide cathode and graphene oxide/gold nanoparticle/glucose oxidase anode. Redox probe of [Fe(CN)6]3- is entrapped inside porous Fe3O4 nanoparticles by DNA. However, in the presence of target miRNA, hybridization reaction occurs between miRNA and DNA, which initiates the release of [Fe(CN)6]3-. Moreover, duplex specific nuclease is further employed to trigger target recycling amplification. As a result, much more redox probes are released and the open circuit voltage is significantly increased. A "signal-on" self-powered biosensor for miRNA quantification is thus developed. The detection range is from 10 aM to 10 fM; meanwhile, the limit of detection is as low as 1.4 aM, which is superior to that in most reported methods. Therefore, the proposed biosensor is expected to be a powerful point-of-care tool for miRNA diagnostics, which may have wide applications in the future. PMID- 30303366 TI - Unraveling the Photodeprotection Mechanism of Anthraquinon-2-ylmethoxycarbonyl Caged Alcohols Using Time-Resolved Spectroscopy. AB - Anthraquinone (AQ) compounds have been used as photolabile protecting groups (PPGs) to protect alcohols, ketones, and carboxylic acids. However, because of the lack of direct spectroscopic information for the transient species and intermediates related with the deprotection reaction(s), the photorelease mechanism(s) of these systems are still largely unknown. In this contribution, we detail a time-resolved spectroscopic investigation using anthraquinone-protected galactose (1) and adenosine (2) to investigate the photodeprotection reaction mechanism(s) of these kinds of AQ-PPGs. It was found that, in THF-H2O solvents, the ketyl radical species generated for 1 and 2 was found to be a reactive intermediate that then formed a dihydroxyanthracene species. The photodeprotection then occurred with the accompaniment of a decarboxylation process. These results provide an improved understanding for how AQ-PPGs work and will help assist in the design and applications of selected anthraquinone derivatives as a PPG platform, especially in aqueous environments more relevant for use in biological systems. PMID- 30303367 TI - Allosteric Inhibition of a Mammalian Lectin. AB - Glycan-binding proteins are key components of central physiological and cellular processes such as self-/non-self-recognition, cellular tissue homing, and protein homeostasis. Herein, C-type lectins are a diverse protein family that play important roles in the immune system, rendering them attractive drug targets. To evaluate C-type lectin receptors as target proteins for small-molecule effectors, chemical probes are required, which are, however, still lacking. To overcome the supposedly poor druggability of C-type lectin receptors and to identify starting points for chemical probe development, we screened murine langerin using 1H and 19F NMR against a library of 871 drug-like fragments. Subsequently, hits were validated by surface plasmon resonance and enzyme-linked lectin assay. Using structure-activity relationship studies and chemical synthesis, we identified thiazolopyrimidine derivatives with double-digit micromolar activity that displayed langerin selectivity. Based on 1H-15N HSQC NMR and competitive binding and inhibition experiments, we demonstrate that thiazolopyrimidines allosterically inhibit langerin. To the best of our knowledge, this is the first report of drug-like allosteric inhibitors of a mammalian lectin. PMID- 30303368 TI - Inverse Sandwich Cyclopentadienyl Complexes of Sodium in the Gas Phase. AB - Infrared multiple photon dissociation (IRMPD) experiments and electronic structure computations have been used to explore the structures and energetics of binding in gas phase sodium cyclopentadienyl complexes of the general form Na nCp n-1+. Computational work for the analogous anionic Na nCp n+1- complexes reveals nearly identical energetics for the loss of neutral NaCp units from both cationic and anionic species leading to the conclusion that the binding in the gas phase species is largely electrostatic, arising primarily from ion-ion and ion-dipole interactions. This is supported by an examination of the molecular orbitals of these species, which show no orbital overlap between the Na and Cp moieties. Observation of peaks in the IRMPD spectra, which do not correspond to any of the computed linear absorption frequencies, strongly suggest the contribution of overtone and combination bands. PMID- 30303369 TI - I2-Mediated Iodobenzannulation of Yne-Allenones toward 1-Naphthols and Their Synthetic Application. AB - A new I2-mediated iodobenzannulation of yne-allenones has been established, enabling breaking/rearranging of C=C bonds to selectively access 4-iodonaphthalen 1-ols with generally good yields. The resulting 4-iodonaphthalen-1-ols could serve as a new and reliable coupling reagent, which further reacted with H2O under the oxygen conditions to generate unexpected 1,2-carbonyls with good yields through Pd-catalyzed deiodinated carbonylation, whereas employment of benzene-1,2 diamine as the nucleophile rendered 3-(quinoxalin-2-yl)naphthalen-1-ols through Pd-catalyzed [4 + 2] heterocyclization. On the basis of the controlled experiments, the mechanism for forming 1,2-carbonyls was proposed, including an oxidative addition, 1,3-palladium migration, reductive elimination, and oxidative dehydrogenation sequence. PMID- 30303370 TI - Highly Reliable Superhydrophobic Protection for Organic Field-Effect Transistors by Fluoroalkylsilane-Coated TiO2 Nanoparticles. AB - One of the long-standing problems in the field of organic electronics is their instability in an open environment, especially their poor water resistance. For the reliable operation of organic devices, introducing an effective protection layer using organo-compatible materials and processes is highly desirable. Here, we report a facile method for the depositing of an organo-compatible superhydrophobic protection layer on organic semiconductors under ambient conditions. The protection layer exhibiting excellent water-repellent and self cleaning properties was deposited onto organic semiconductors directly using a dip-coating process in a highly fluorinated solution with fluoroalkylsilane coated titanium dioxide (TiO2) nanoparticles. The proposed protection layer did not damage the underlying organic semiconductors and had good resistance against mechanical-, thermal-, light-stress-, and water-based threats. The protected organic field-effect transistors exhibited more-reliable electrical properties, even when exposed to strong solvents, due to its superhydrophobicity. This study provides a practical solution with which to enhance the reliability of environmentally sensitive organic semiconductor devices in the natural environment.

All of them feature the [MB5O10] n2 n- (M = Al or Ga) frameworks, charge-balanced by the long chain-like amine cations. Three frameworks exhibit different interlinkage modes of {MB5O10} layers, resulting in channels varying in size and shape. The flexibility of long chain-like amine cations as well as their significant structure-directing functions in forming these crystalline products is also discussed in detail. Powder second-harmonic generation measurements showed that all three compounds present a nonlinear optical property, and compound 2 exhibits type I phase matchable optical nonlinearity. PMID- 30303372 TI - A High-Resolution Spatial Model to Predict Exposure to Pharmaceuticals in European Surface Waters: ePiE. AB - Environmental risk assessment of pharmaceuticals requires the determination of their environmental exposure concentrations. Existing exposure modeling approaches are often computationally demanding, require extensive data collection and processing efforts, have a limited spatial resolution, and have undergone limited evaluation against monitoring data. Here, we present ePiE (exposure to Pharmaceuticals in the Environment), a spatially explicit model calculating concentrations of active pharmaceutical ingredients (APIs) in surface waters across Europe at ~1 km resolution. ePiE strikes a balance between generating data on exposure at high spatial resolution while having limited computational and data requirements. Comparison of model predictions with measured concentrations of a diverse set of 35 APIs in the river Ouse (UK) and Rhine basins (North West Europe), showed around 95% were within an order of magnitude. Improved predictions were obtained for the river Ouse basin (95% within a factor of 6; 55% within a factor of 2), where reliable consumption data were available and the monitoring study design was coherent with the model outputs. Application of ePiE in a prioritisation exercise for the Ouse basin identified metformin, gabapentin, and acetaminophen as priority when based on predicted exposure concentrations. After incorporation of toxic potency, this changed to desvenlafaxine, loratadine, and hydrocodone. PMID- 30303373 TI - Correction to Dynamic Sparse Sampling for Confocal Raman Microscopy.

AB - There were several studies that measured organophosphate esters (OPEs) in foods to assess the dietary intake of OPEs but none has measured OPE metabolites (mOPEs) in the same samples. In this study, we measured the concentrations of OPEs and mOPEs in 87 food samples and in five tap water samples collected in Queensland, Australia belonging to eight food groups. Tris(2-chloroisopropyl) phosphate (TCIPP) (detection frequency (DF), 77%) and tributyl phosphate (TBP) (DF, 71%), were the most frequently detected OPEs, while dibutyl phosphate (DBP) (DF, 84%) and diphenyl phosphate (DPhP) (DF, 86%) were the most frequently detected mOPEs. Vegetables had the highest concentrations of both ?9OPEs and ?11mOPEs, with the mean concentrations of 2.6 and 17 ng/g wet weight. Compared with dust ingestion and inhalation, dietary intake was the most important exposure pathway for tris(2-chloroethyl) phosphate (TCEP) (4.1 ng/kg bw/day), TCIPP (25 ng/kg bw/day), and TBP (6.7 ng/kg bw/day), accounting for >75% of total intake. Furthermore, we found that the intakes of some mOPEs, that is, bis(1,3 dichloroisopropyl) phosphate (BDCIPP) and DPhP from diet were typically higher than that of their parent OPEs. Such high levels of mOPE intakes could interfere with the utilization of mOPEs as biomarkers for assessing OPE exposure and warrant further investigation.

AB - A domino silver(I)-promoted electrocyclic 2pi-disrotatory electrocyclic ring opening/intramolecular nucleophilic trapping of [ n.1.0]-dibromocyclopropanes by tethered carboxylic acids results in cyclization to butyrolactones fused to six- and seven-membered carbocycles. In the case of bicyclic [4.3.0] lactones the cis fused stereoisomer was formed, whereas for the bicyclic [5.3.0] lactones the trans-fused stereoisomer was formed. Optimal conditions for the reaction used silver(I) trifluoroacetate (2.0 equiv) in trifluoroethanol or with added pyridine (2.0 equiv) and NaPF6 (5.0 equiv). The dibromocyclopropane precursors were made through cyclopropanation with in situ-generated dibromocarbene. The trans-fused lactones are potentially useful building blocks for pseudoguaianolide, guaianolide, and xanthanolide total synthesis. A computational study on the conformational preferences of these systems indicates that the trans-fused bicyclic [5.3.0] butyrolactones are lower in energy than the corresponding cis fused lactones at the B3LYP/cc-pVTZ level of theory.

AB - We propose a pairwise and readily parallelizable SASA-based nonpolar solvation approach for protein simulations, inspired by our previous pairwise GB polar solvation model development. In this work, we developed a novel function to estimate the atomic and molecular SASAs of proteins, which results in comparable accuracy as the LCPO algorithm in reproducing numerical icosahedral-based SASA values. Implemented in Amber software and tested on consumer GPUs, our pwSASA method reasonably reproduces LCPO simulation results, but accelerates MD simulations up to 30 times compared to the LCPO implementation, which is greatly desirable for protein simulations facing sampling challenges. The value of incorporating the nonpolar term in implicit solvent simulations is explored on a peptide fragment containing the hydrophobic core of HP36 and evaluating thermal stability profiles of four small proteins.

Herein, we describe the development of a TiIII-catalyzed radical addition of 2 degrees and 3 degrees alkyl chlorides to electron-deficient alkenes. Mechanistic data are consistent with inner-sphere activation of the C-Cl bond featuring TiIII-mediated Cl atom abstraction. Evidence suggests that the active TiIII catalyst is generated from the TiIV precursor in a Lewis-acid-assisted electron transfer process.

AB - We present isomerism in a few supramolecular adducts of atomically precise nanoparticles, [Ag29(BDT)12?(CD) n]3- ( n = 1-6), abbreviated as I where BDT and CD are 1,3-benzenedithiol and cyclodextrins (alpha, beta and gamma), respectively; ? symbolizes an inclusion complex. The different host-guest complexes of I were characterized in the solution state as well as in the gas phase. The CDs (alpha, beta and gamma) encapsulate a pair of BDT ligands protecting the Ag29 core. This unique geometry of the supramolecular adducts makes the system similar to octahedral complexes of transition metals, which manifest various isomers. These isomers of I ( n = 2-4) were separated by ion mobility mass spectrometry (IM MS). We proposed structures of all the inclusion complexes with the help of IM MS measurements and molecular docking, density functional theory (DFT), and collision cross section (CCS) calculations.

AB - ZnS nanosystems are being extensively studied for their possible use in a wide range of technological applications. Recently, the gradual oxidation of ZnS to ZnO was exploited to tune their structural, electronic, and functional properties. However, the inherent complexity and size dependence of the ZnS oxidation phenomena resulted in a very fragmented description of the process. In this work, different-sized nanosystems were obtained through two different low temperature wet chemistry routes, namely, hydrothermal and inverse miniemulsion approaches. These protocols were used to obtain ZnS samples consisting of 21 and 7 nm crystallites, respectively, to be used as reference material. The obtained samples were then calcinated at different temperatures, ranging from 400 to 800 degrees C toward the complete oxidation of ZnO, passing through the coexistence of the two phases (ZnS/ZnO). A thorough comparison of the effects of thermal handling on ZnS structural, chemical, and functional evolution was carried out by TEM, XRD, XAS, XPS, Raman, FT-IR, and UV-Vis. Finally, the photocatalytic activity in the H2 evolution reaction was also compared for selected ZnS and ZnS/ZnO samples. A correlation between size and the oxidation process was observed, as the smaller nanosystems showed the formation of ZnO at lower temperature, or in a larger amount in the case of the ZnS and ZnO co-presence. A difference in the underlying mechanism of the reaction was also evidenced. Despite the ZnS/ZnO mixed samples being characterized by an increased light absorption in the visible range, their photocatalytic activity was found to be much lower.

AB - Theionbrunonines A and B (1 and 2), the first examples of monoterpene bisindole alkaloids linked by a thioether bridge, were isolated from the stems of Mostuea brunonis, guided by a molecular networking-based dereplication strategy. Their structures were elucidated by a combination of spectroscopic data and ECD calculations. A plausible biosynthetic pathway for 1 and 2 was postulated. Theionbrunonines A and B (1 and 2) showed moderate antiplasmodial activities in the micromolar range against the strain FcB1 of Plasmodium falciparum and no cytotoxic activity against the MRC-5 cell line at 20 MUM. PMID- 30303383 TI - Experimental Characterization of Droplet Adhesion: The Ejection Test Method (ETM) Applied to Surfaces with Various Hydrophobicity. AB - We study the wetting and the adhesive behavior of substrates made by electropolymerization of copolymers of pyrene substituted with fluoroalkyl and adamantyl groups. The hydrophobicity and water adhesion properties can be tuned by the molar percentage (mol %) of each pyrene monomer so that the substrate properties can vary from superhydrophobic to parahydrophobic, with respectively low and high water adhesion. The ejection test method (ETM) is proposed as an original tool to discriminate and characterize such substrates. Using a catapult like apparatus, a droplet initially at rest on the surface is subject to a large acceleration and is subsequently ejected. Depending on the surface properties and initial catapult acceleration, the ejection is more or less efficient and occurs with or without fragmentation of the droplet. The ETM is shown to be a complementary test to the lateral adhesion and hysteresis classical measurements. This work is of importance for the understanding of adhesion phenomena on various surfaces and for a better quantitative characterization of their adhesive properties.

AB - Photodynamic therapy (PDT) is a light-triggered therapy used to kill cancer cells by producing reactive oxygen species (ROS). Herein, a new kind of DNA nanostructure based on the coordination between calcium ions (Ca2+) and AS1411 DNA G quadruplexes to form nanoscale coordination polymers (NCPs) is developed via a simple method. Both chlorine e6 (Ce6), a photosensitizer, and hemin, an iron-containing porphyrin, can be inserted into the G-quadruplex structure in the obtained NCPs. With further polyethylene glycol (PEG) modification, we obtain Ca AS1411/Ce6/hemin@pHis-PEG (CACH-PEG) NCP nanostructure that enables the intranuclear transport of photosensitizer Ce6 to generate ROS inside cell nuclei that are the most vulnerable to ROS. Meanwhile, the inhibition of antiapoptotic protein B-cell lymphoma 2 (Bcl-2) expression by AS1411 allows for greatly improved PDT-induced cell apoptosis. Furthermore, the catalase-mimicking DNAzyme function of G-quadruplexes and hemin in those NCPs could decompose tumor endogenous H2O2 to in situ generate oxygen so as to further enhance PDT by overcoming the hypoxia-associated resistance. This work develops a simple yet general method with which to fabricate DNA-based NCPs and presents an interesting concept of a nanoscale drug-delivery system that could achieve the intranuclear delivery of photosensitizers, the down-regulation of anti-apoptotic proteins, and the modulation of the unfavorable tumor microenvironment simultaneously for improved cancer therapy. PMID- 30303386 TI - Stereoselective Allylic Alkylation of 1-Pyrroline-5-carboxylic Esters via a Pd/Cu Dual Catalysis. AB - The asymmetric allylation of 1-pyrroline-5-carboxylic esters has been accomplished through a synergistic Pd/Cu catalyst system under mild reaction conditions. The mechanistic studies suggested that (1) nucleophilic attack is the enantiodiscriminating step; (2) the cooperative action of two chiral reactive species, N-metalated azomethine ylides and pi-allylpalladium, is most likely responsible for its high reactivity and excellent enantioselectivity (up to >99% ee); and (3) the steric hindrance and electronic factors of the allylic electrophiles and imino ester substrates are crucial for the formation of the linear products. A series of 3,4-2 H-pyrrole derivatives bearing a quaternary stereogenic center were easily synthesized in high yields and with high to excellent regioselectivity and enantioselectivity. PMID- 30303385 TI - Combining Mass Spectrometry and NMR Improves Metabolite Detection and Annotation. AB - Despite inherent complementarity, nuclear magnetic resonance spectroscopy (NMR) and mass spectrometry (MS) are routinely separately employed to characterize metabolomics samples. More troubling is the erroneous view that metabolomics is better served by exclusively utilizing MS. Instead, we demonstrate the importance of combining NMR and MS for metabolomics by using small chemical compound treatments of Chlamydomonas reinhardtii as an illustrative example. A total of 102 metabolites were detected (82 by gas chromatography-MS, 20 by NMR, and 22 by both techniques). Out of these, 47 metabolites of interest were identified: 14 metabolites were uniquely identified by NMR, and 16 metabolites were uniquely identified by GC-MS. A total of 17 metabolites were identified by both NMR and GC MS. In general, metabolites identified by both techniques exhibited similar changes upon compound treatment. In effect, NMR identified key metabolites that were missed by MS and enhanced the overall coverage of the oxidative pentose phosphate pathway, Calvin cycle, tricarboxylic acid cycle, and amino acid biosynthetic pathways that informed on pathway activity in central carbon metabolism, leading to fatty-acid and complex-lipid synthesis. Our study emphasizes a prime advantage of combining multiple analytical techniques: the improved detection and annotation of metabolites. PMID- 30303387 TI - Modified Pluronic F127 Surface for Bioconjugation and Blocking Nonspecific Adsorption of Microspheres and Biomacromolecules. AB - Many experiments and applications require the chemical coupling of target molecules to surfaces, during which the elimination of nonspecific interactions presents a difficult challenge. We report on a technologically accessible surface passivation and chemical conjugation method based on an NHS end-labeled F127 Pluronic block copolymer (F127-NHS). To quantify interactions between the F127 NHS surface and magnetic microspheres, we developed a simple assay: the microsphere adhesion by gravity, inversion, then counting, or "MAGIC" assay. To improve blocking of microspheres while maintaining the ability to chemically couple additional molecules, we implemented a pH-dependent two-step chemical modification process for amine microspheres. This process achieves an extremely high level of blocking nonspecific interactions (less than 2% nonspecific adhesion) for a variety of microsphere surface charges and chemical functionalities. We also demonstrate the ability to specifically tether magnetic microspheres to an F127-NHS surface, using single DNA molecules. Using the DNA microspheres, we establish the applicability of the surface for force spectroscopy (stable with an applied load >30 pN) via the massively parallel technique of centrifuge force microscopy. Finally, we demonstrate that the surface can be used in fluorescence studies with a fluorogenic peptide cleavage assay, with high levels of blocking achieved for both the fluorogenic peptide and trypsin. These results suggest applications including, but not limited to, single molecule force spectroscopy and fluorescence, biosensors, medical implants, and anti-biofouling, which could make use of the F127-NHS surface. PMID- 30303388 TI - Highly Selective Synthesis of Pillar[ n]arene ( n = 5, 6). AB - An efficient and highly selective synthetic method toward the preparation of pillar[ n]arenes ( n = 5, 6) is reported, based upon a high solvent-dependent selectivity found in the condensation reaction between 1,4-dialkyloxybenzene and paraformaldehyde, involving methanesulfonic acid as catalyst. Pillar[6]arene (P6) is obtained as the major product when using chloroform as solvent, while in dichloromethane pillar[5]arene (P5) is the dominant product. Accordingly, a series of P5 and P6 have been selectively synthesized with excellent yield. PMID- 30303389 TI - Macrolactonization of Alkynyl Alcohol through Rh(I)/Yb(III) Catalysis. AB - A catalytic macrolactonization through oxidative cyclization of alkynyl alcohol by synergistic transition-metal and Lewis-acid catalysis was developed. Because the alkynyl alcohol substrates involved in this method are different from the seco acids that are used in conventional macrolactonization methods, the current method provides a strategically distinct entry to macrolactones. In addition to the operational simplicity, this macrolactonization protocol proceeds at relatively high concentration, precluding the need for high dilution or slow addition procedures. PMID- 30303390 TI - Osmotic Shock-Triggered Assembly of Highly Charged, Nanoparticle-Supported Membranes. AB - Spherical nanoparticle-supported lipid bilayers (SSLBs) combine precision nanoparticle engineering with biocompatible interfaces for various applications, ranging from drug delivery platforms to structural probes for membrane proteins. Although the bulk, spontaneous assembly of vesicles and larger silica nanoparticles (>100 nm) robustly yields SSLBs, it will only occur with low charge density vesicles for smaller nanoparticles (<100 nm), a fundamental barrier in increasing SSLB utility and efficacy. Here, through whole mount and cryogenic transmission electron microscopy, we demonstrate that mixing osmotically loaded vesicles with smaller nanoparticles robustly drives the formation of SSLBs with high membrane charge density (up to 60% anionic lipid or 50% cationic lipid). We show that the osmolyte load necessary for SSLB formation is primarily a function of absolute membrane charge density and is not lipid headgroup-dependent, providing a generalizable, tunable approach toward bulk production of highly curved and charged SSLBs with various membrane compositions.

AB - The first asymmetric nucleophilic fluorination at the sp3-tertiary carbon center has been developed using inexpensive tetrabutylammonium fluoride (TBAF) without any metal/catalyst for the synthesis of 3-fluoro-3-substituted oxindoles with excellent enantioselectivity (ee up to >99%). Regio- and stereocontrolled ring opening of spiroaziridine with retention of configuration and other experiments revealed that the fluorination proceeded through an anchimeric assistance. PMID- 30303392 TI - Solid-State 31P Nuclear Magnetic Resonance Study of Interlayer Hydroxide Surfaces of Kaolinite Probed with an Interlayer Triethylphosphine Oxide Monolayer. AB - The solid acidity of the interlayer aluminol surfaces of kaolinite was explored by solid-state 31P nuclear magnetic resonance with magic angle spinning (MAS) using triethylphosphine oxide (TEPO), which formed a monolayer with a uniform orientation between the layers of kaolinite as a probe molecule. Intercalation of TEPO between the layers of kaolinite was achieved using methoxy-modified kaolinite as an intermediate. The presence of TEPO in the reaction products was revealed by the two signals at 21 and 7 ppm, which were assignable to ethyl groups in TEPO, in the solid-state 13C nuclear magnetic resonance with cross polarization and magic angle spinning techniques (13C CP/MAS NMR). The presence of TEPO between the layers of kaolinite was demonstrated by the expansion of basal spacing from 0.86 nm, the interlayer distance of methoxy-modified kaolinite to 1.16 nm, as shown by the X-ray diffraction patterns, suggesting the formation of a TEPO monolayer between the layers of kaolinite. The formation of hydrogen bonds between the P?O groups of TEPO and the aluminol groups on the interlayer surfaces of kaolinite was also revealed by the appearance of an additional OH stretching band at 3598 cm-1 in the Fourier-transform infrared spectrum and narrow solid-state 31P MAS NMR signals observed at 55-53 ppm which were shifted from the position of the physisorbed TEPO (50 ppm). These results clearly indicate that the solid acidity of interlayer aluminol groups of methoxy-modified kaolinite was probed using an interacted TEPO monolayer. PMID- 30303393 TI - Influence of pH and Salt Concentration on Pickering Emulsions Stabilized by Colloidal Peanuts. AB - Solid-stabilized emulsions commonly known as Pickering emulsions offer unique benefits such as superior stability and controlled permeability compared to conventional surfactant stabilized emulsions. In this article, the effect of pH, the electrolyte and particle concentration, homogenization speed, and volume fraction of oil on the formation, stability, and the microstructure of emulsion droplets stabilized by micron-size peanut-shaped hematite particles are investigated. The influence of surface charge of particles on emulsification is studied by varying the pH of the dispersing medium, the addition of an electrolyte or a combination of both. Stable O/W emulsions are formed only when the aqueous dispersions at intermediate pH between 4 and 11, and decane (2:1 volume ratio) are vigorously mixed. However, emulsions are not formed when the particles are highly charged that is, at pH 2 and 12. The presence of monovalent salt or high-speed homogenization assists the emulsion formation at pH 3, whereas their combination helps in emulsification at pH 2. However, neither the addition of an electrolyte nor the high-speed homogenization or their combination facilitates the formation of emulsions at pH 12. We show that the image-charge repulsion and the surface charge induced wettability change can explain the influence of both pH and salt concentrations on the formation of Pickering emulsions. Although oil-in-water emulsions typically cream because of the density difference, microscopy observations revealed the presence of a large number of small particle-covered oil droplets in the sediments of the emulsified samples. These drops are observed to be entrapped in dense-particle networks. This leads to a considerable reduction in the number of particles available for the stabilization of floating emulsion droplets and thus influences their size and surface coverage. The possibility of tailoring the stability, droplet size and, the surface coverage discussed in this article can play a crucial role in situations that demand controlled release of active components. PMID- 30303394 TI - Memory training for adults with probable mild cognitive impairment: a pilot study. AB - BACKGROUND & OBJECTIVES: This pilot study aimed to evaluate the efficacy of memory training and health training intervention over a 24-month period in people with probable mild cognitive impairment (MCI). RESEARCH DESIGN & METHODS: Based on the accepted criteria, and the neuropsychiatric measures used in the trial, MCI was defined as a subjective change in cognition, impairment in episodic memory, preservation of independence of functional abilities, and no dementia. Without a neurological assessment, laboratory tests, and psychometric evaluation combined, some of our participants may have had dementia that we were unable to detect through neuropsychological testing. Of the 263 total participants, 39 met criteria for a diagnosis of MCI. There were 19 adults in the memory and 20 in health training conditions. Both groups received twenty hours of classroom content that included eight hours of booster sessions at three months post intervention. Hierarchical linear models (HLM) and standardized regression-based (SBR) analyses were used to test the efficacy of the intervention on immediate recall, delayed recall, subjective memory complaints, and memory self-efficacy. Age, education, depression, racial group, ethnic group, MMSE score, and baseline performance were included as covariates. RESULTS: Over 24 months, the MCI group in the memory training condition showed better objective and subjective memory outcomes compared with the MCI group in the health training condition. CONCLUSIONS: Senior WISE Memory training delivered to individuals with MCI was able to forestall the participants' declining cognitive ability and sustain the benefit over two years in both subjective and objective memory function. PMID- 30303395 TI - Early Pulmonary Vascular Disease in Preterm Infants is Associated with Late Respiratory Outcomes in Childhood. AB - RATIONALE: Early pulmonary vascular disease (PVD) after preterm birth is associated with a high risk for developing bronchopulmonary dysplasia (BPD), but its relationship with late respiratory outcomes during early childhood remains uncertain. OBJECTIVE: To determine whether PVD at 7 days after preterm birth is associated with late respiratory disease (LRD) during early childhood. METHODS: Prospective study of preterm infants born before 34 weeks postmenstrual age (PMA). Echocardiograms were performed at 7 days and 36 weeks PMA. Prenatal and early postnatal factors and post-discharge follow-up survey data obtained at 6, 12,18, and 24 months of age were analyzed in logistic regression models to identify early risk factors for LRD, defined as a physician diagnosis of asthma, reactive airways disease, BPD exacerbation, bronchiolitis, or pneumonia, or a respiratory-related hospitalization during follow-up. RESULTS: Of the 221 subjects (median 27 weeks PMA; IQR: 25-28 and 920g; IQR: 770g-1090g) completing follow-up, 61% met LRD criteria. Gestational diabetes, mechanical ventilator support (MV) and PVD at 7 days were associated with LRD. The combination of PVD and MV support at 7 days was among the strongest predictors of LRD (OR: 8.1; CI: 3.1 - 21.9, p<0.001). Modeled prenatal and early postnatal factors accurately predicted LRD (AUC 0.764). Adding BPD status at 36 weeks PMA to the model did not change the accuracy (AUC 0.771). CONCLUSIONS: Early echocardiographic evidence of PVD after preterm birth in combination with other perinatal factors is a strong risk factor for LRD, suggesting that early PVD may contribute to the pathobiology of BPD. PMID- 30303396 TI - Olive mill wastewaters: quantitation of the phenolic content and profiling of elenolic acid derivatives using HPLC-DAD and HPLC/MS2 with an embedded polar group stationary phase. AB - Olive mill wastewaters (OMWs) are important by-products of olive oil production. The wide availability and the forbidding economic costs of OMWs disposal have generated interest in their possible exploitation as a sustainable source of polyphenols. The development and optimisation of improved analytical methods for the detailed characterisation of polyphenol molecular profiles after production and during storage conditions are thus required. A new analytical method based on reverse-phase HPLC separation of polyphenols in OMWs on an embedded-polar group (EPG) stationary phase is proposed as an alternative to conventional C18 columns. The procedure was used for the quantitation of 11 polyphenols, using diode-array detection (DAD), and achieving quantitation limits equal to or lower than 0.1 ug g-1. The same chromatographic set-up, coupled with high resolution tandem mass spectrometry (HPLC/ESI-Q-ToF), allowed us to identify hydroxytyrosyl esters of elenolic acid, whose relative abundance is proposed for monitoring the ageing of OMWs during storage. PMID- 30303397 TI - Social communication assessment after TBI: a narrative review of innovations in pragmatic and discourse assessment methods. AB - BACKGROUND: Social communication assessment after traumatic brain injury (TBI) remains a challenging area within speech-language pathology (SLP) clinical practice. Difficulties include the lack of TBI-specific standardized assessment instruments and limited knowledge and uptake of discourse assessment methods clinically. The aim of this paper was to review recent research literature reporting on innovative social communication and discourse assessment measures and methods, to guide evidence-based SLP practice and inform future research. MAIN CONTRIBUTION: This review describes novel standardized and non-standardized assessment tools for SLP use reported in TBI research literature from the past 15 years. Measures include published assessment batteries and pragmatic rating scales designed for use with adults with TBI, and novel discourse tasks and protocols. CONCLUSION: This paper delineates social communication assessment measures and discourse analyses described in research literature that may be practical for SLPs to use with adults with TBI. The clinical implications and utility of these measures are discussed. This should assist SLPs in decision making on social communication assessment for adults with TBI. Further research is needed to investigate translation of research knowledge on discourse assessment methods to SLP practice.

AB - This study aims to determine the validity and reliability of applying the coding strategy from the Brief Observation of Social Communication Change, a newly validated treatment outcome measure, to videotaped segments of the Autism Diagnostic Observation Schedule. Results indicate strong reliability and validity of the Brief Observation of Social Communication Change ratings using the Autism Diagnostic Observation Schedule segments in detecting changes in social communication over the course of treatment in young, minimally verbal children with autism spectrum disorder. Results also suggest that the Brief Observation of Social Communication Change, when applied to Autism Diagnostic Observation Schedule segments, may be more sensitive in detecting subtle changes in social communication compared to the Autism Diagnostic Observation Schedule Calibrated Severity Scores. These results may support the application of the Brief Observation of Social Communication Change to pre-existing datasets of Autism Diagnostic Observation Schedule videos to examine treatment responses. PMID- 30303399 TI - A Phenomenological Study of Italian Students' Responses to Professional Dilemmas: A Cross-Cultural Comparison. AB - : Phenomenon: Medical professionalism is a complex construct, based in social and cultural influences, yet little research has been done to show how culture influences the behaviors and attitudes of medical students. We presented Italian students with the same professional dilemmas used in a previous Canadian and Taiwanese cross-cultural study to look for similarities and differences and detect elements of Italian culture that influenced how students responded to dilemmas. The aim was to provide medical educators with some insights into students' behavioral strategies and feelings when faced with a professional dilemma. APPROACH: Using Giorgi's method, we performed a phenomenological analysis of 15 interviews of Italian medical students who responded to standardized video scenarios representing professional dilemmas. These videos were used in Canada and Taiwan and were translated into Italian. All students were from the same degree course, at Year 6, and were recruited on a voluntary basis at the beginning of the Internal Medicine course. Interview transcripts were anonymized before analysis. FINDINGS: Scenarios were perceived as realistic and easy to envision in Italy. Four themes emerged: establishing priority among principles, using tactics to escape the dilemma, defending the self, and defending the relationships. When compared with previous studies, we noted that Italian students did not mention the principles of reporting inappropriate behavior, seeking excellence, or following senior trainees' advice. Insights: This is the first cross-cultural study of professionalism that involves a Mediterranean country and the observed differences could be interpreted as expressions of Italian cultural traits: distrust toward authority and a cooperative rather than competitive attitude. These findings have practical implications for educators to design and run curricula of professionalism with culturally appropriate topics. They highlight the need for more cross-cultural research.

AB - AIMS: There are very few studies comparing epidemiology and outcomes of out-of hospital cardiac arrest (OHCA) in different ethnic groups. Previous ethnicity studies have mostly determined OHCA differences between African American and Caucasian populations. The aim of this study was to compare epidemiology, clinical presentation, and outcomes of OHCA between the local Middle Eastern Gulf Cooperation Council (GCC) Arab and the migrant North African populations living in Qatar. METHODS: This was a retrospective cohort study of Middle Eastern GCC Arabs and migrant North African patients with presumed cardiac origin OHCA resuscitated by Emergency Medical Services (EMS) in Qatar, between June 2012 and May 2015. RESULTS: There were 285 Middle Eastern GCC Arabs and 112 North African OHCA patients enrolled during the study period. Compared with the local GCC Arabs, univariate analysis showed that the migrant North African OHCA patients were younger and had higher odds of initial shockable rhythm, pre-hospital interventions (defibrillation and amioderone), pre-hospital scene time, and decreased odds of risk factors (hypertension, respiratory disease, and diabetes) and pre-hospital response time. The survival to hospital discharge had greater odds for North African OHCA patients which did not persist after adjustment. Multivariable logistic regression showed that North Africans were associated with lower odds of diabetes (OR 0.48, 95% CI 0.25-0.91, p = 0.03), and higher odds of initial shockable rhythm (OR 2.86, 95% CI 1.30-6.33, p = 0.01) and greater scene time (OR 1.02 95% CI 1.0-1.04, p = 0.02). CONCLUSIONS: North African migrant OHCA patients were younger, had decreased risk factors and favourable OHCA rhythm and received greater ACLS interventions with shorter pre-hospital response times and longer scene times leading to better survival. PMID- 30303401 TI - An in-depth look into the association between morningness-eveningness and well being: evidence for mediating and moderating effects of personality. AB - Morningness-eveningness and standard personality traits are associated with well being but few studies have directly compared the two types of construct as correlates of life satisfaction. Influences on well-being common to both chronotype and personality may include shared biological bases for depression and sleep disturbance, tendencies toward social jetlag, and emotion-regulation mechanisms. The current study tested mediation and moderation hypotheses in a sample of 379 Polish adults. The first hypothesis was that conscientiousness and emotional stability traits would mediate the relationship between morningness and life satisfaction. Consistent with previous results, morningness, the two personality traits, and satisfaction tended to be mutually positively correlated. A multiple mediation analysis showed that both traits partially mediated the morningness-satisfaction association. Data are compatible with morningness influencing personality development adaptively, although other causal hypotheses could be advanced. The second hypothesis was that extraversion would moderate the association between chronotype and satisfaction. This hypothesis was supported, with extraverted evening types showing disproportionately high life satisfaction, whereas introverted evening types showed the lowest levels of satisfaction. Level of extraversion may influence whether or not evening types choose to engage in adaptive social activities that boost well-being during the evening hours. Results demonstrate the importance of investigating both chronotype and personality in studies of well-being. PMID- 30303402 TI - Assessing mechanisms of benefit in adult day programs: the adult day services process and use measures. AB - OBJECTIVES: A limitation of adult day service (ADS) research is that there remains little understanding of how these community-based long-term care programs operate to benefit clients or family caregivers (i.e. the process of ADS use). The purpose of this study was to validate the 'ADS Process and Use Measures' (APUM) which were developed to assess such mechanisms. METHOD: Participant observation and semi-structured interviews in two ADS settings resulted in qualitative data to inform a conceptual model, subscales, and Likert-scale items. Three experts in ADS research reviewed the initial 129-item version of the APUM to establish content validity, and 27 family caregivers of current or prior ADS clients provided feedback on face validity of a subsequent 58-item version. RESULTS: Principal components and confirmatory factor analyses on a sample of 269 family members of ADS clients recruited from 90 programs throughout the U.S. established a measure featuring 5 domains, 12 reliable subscales, and 49 items. Analysis of discriminant and convergent validity found that various subscales from four of the domains (Why ADS is Used, Events Prior to Use, Why ADS Does Not Work, and Pathways to Benefits) were significantly associated (p < 0.05) with family caregiver distress and ADS client quality of life variables. CONCLUSION: The ADS Process and Use Measures effectively assess mechanisms of program benefit and could help to enhance the overall quality of these critical community-based long-term care options for older persons and their families. PMID- 30303403 TI - Keystone: Exploring Pediatric Residents' Experiences in a Longitudinal Integrated Block. AB - PROBLEM: Residency training in many specialties has traditionally been divided into short, discrete, single-specialty rotations. Although providing the learner with in-depth exposure to a specific discipline, educators have challenged this rotational model, citing problems with patient and team continuity and maladaptive coping. Longitudinal integrated clerkships, adopted by many medical schools, offer an alternative model and have demonstrated improved outcomes for students related to patient-centeredness, advocacy, and integration with teams. Despite this, longitudinal integrated training in residency is rare. INTERVENTION: We developed a novel 3-month longitudinal integrated block for residents, called Keystone. The block combined 3 previously discrete, shorter rotations in developmental-behavioral pediatrics, advocacy, and emergency medicine into a longer and integrated experience. Within each week, the block utilized half-day sessions in the resident's primary care clinic, a new continuity Developmental Behavioral Pediatrics clinic where the resident worked with the same faculty preceptor and interprofessional team each week, shifts in the emergency department, and half-day sessions dedicated to clinic- and community-based advocacy activities. CONTEXT: The context was a single, large pediatric urban residency program based at 2 university-affiliated hospitals, an academic freestanding children's hospital, and academic safety net hospital. OUTCOME: Using a phenomenologic framework, we conducted interviews and a focus group discussion to explore residents' attitudes about the block; their perceptions regarding the block's impact on relationships with preceptors, peers, or patients; and the block's impact on learning and practice. Fourteen residents participated, 10 in interviews and 4 in the focus group discussion. Six themes emerged from thematic analysis: (a) the longitudinal nature of Keystone influenced professional relationships and as a result entrustment, (b) the longitudinal integrated design shaped engagement and learning, (c) flexibility promoted work-life balance and self-directed learning, (d) learners experienced time and space for professional identity development, (e) Keystone provided a unique opportunity to reclaim patient-centeredness, and (f) learners experienced important advantages and challenges related to the schedule. LESSONS LEARNED: The longitudinal integrated nature of Keystone provided a novel structure for addressing important yet challenging educational goals in residency, including enhancing relationships, facilitating entrustment and engagement, encouraging patient-centeredness, and emphasizing the importance of self-directed learning. PMID- 30303404 TI - Association between ambient temperature and chronic obstructive pulmonary disease: a population-based study of the years of life lost. AB - Limited evidence on the burden of chronic obstructive pulmonary disease (COPD) attributable to ambient temperature. We aim to explore the association between ambient temperature and years of life lost (YLL), and to get a more intuitive understanding of the dangers of COPD in China. Death and meteorological data of 31 Chinese provincial capital cities during 2008-2013 was analyzed in this study. Distributed Lag Non-linear Model (DLNM) was used to estimate the association between ambient temperature and mortality. The attributable fraction (AF) to cold effect ranged from 8.19 (95%CI: -8.52,19.38) to 28.98 (95%CI: -64.78,67.59), while the AF to heat effect varied from 0.02 (95%CI: -0.13,0.05) to 5.73 (95%CI: 0.31,10.22). Cold effect was higher than heat effect on COPD in women and elderly, heat effect was higher in men and younger. Low temperature can cause more serious disease burden of COPD than high temperature.

Toward development of a pediatric HIV vaccine to prevent breastmilk transmission, we tested the efficacy of a simultaneous oral and intramuscular (IM) vaccination regimen for preventing oral simian immunodeficiency virus (SIV) transmission in infant rhesus macaques. Two groups of neonatal macaques were immunized with DNA encoding SIV virus-like particles (DNA-SIV) on weeks 0 and 3, then boosted with modified vaccinia Ankara (MVA) virus expressing SIV antigens (MVA-SIV) on weeks 6 and 9. One group was prime/boosted by the IM route only. Another group was immunized with DNA by both the IM and topical oral (O) buccal routes, and boosted with MVA-SIV by both the IM and sublingual (SL) routes. A third group of control animals received saline by O + IM routes on weeks 0 and 3, and empty MVA by SL + IM routes on weeks 6 and 9. On week 12, infants were orally challenged once weekly with SIVmac251 until infected. The vaccine regimen that included oral routes resulted in reduced peak viremia. The rate of infection acquisition in vaccinated infants was found to be associated with prechallenge intestinal immunoglobulin G (IgG) responses to SIV gp120 and V1V2. Peak viremia was inversely correlated with postinfection intestinal IgG responses to gp120, gp41, and V1V2. These results suggest that codelivery of a pediatric HIV vaccine by an oral route may be superior to IM-only regimens for generating mucosal antibodies and preventing HIV breastmilk transmission in neonates. PMID- 30303406 TI - Inducing intravesical hyperthermia of the ex-vivo porcine bladder wall: radiofrequency-induction versus recirculation using a custom-made device. AB - INTRODUCTION: Several techniques can be used to treat intravesical chemohyperthermia (ChHT). We compared radiofrequency-induced hyperthermia (RF-HT) with conductive hyperthermia (C-HT) for their ability to induce bladder wall temperatures of >40.5 degrees C, the target temperature for ChHT. MATERIALS AND METHODS: Fresh porcine bladders (n = 12) were placed in a temperature-controlled saline bath to simulate body temperature and circulation. HT was induced with RF HT (43 degrees C) or C-HT (inflow temperature 44 and 46 degrees C) using a custom-made device. In two additional bladders, we varied intravesical solution and volume. Temperatures were recorded with a three-way catheter containing three mucosal and two urethral thermocouples (TCs) and a 915 MHz RF antenna, and with external TCs in the bladder wall at three different levels and three different locations. RESULTS: Target temperature (40.5 degrees C) was reached in the submucosa at all locations by both techniques. In the detrusor, target temperature was reached by RF-HT at the bladder neck and side wall. C-HT46 reached significantly higher submucosal temperatures at the side wall. The bladder dome seemed best heated by C-HT, although a high inflow temperature (46 vs. 44 degrees C) was required (ns). Intravesical saline resulted in higher temperatures than sterile water for RF-HT. A volume of 100 mL resulted in higher bladder dome temperatures for RF-HT, and higher bladder neck with lower dome temperatures for C-HT. CONCLUSION: Our results indicate a slightly superior heating capacity for RF-HT compared to C-HT, whereas for the bladder dome, the reverse seems true. Comparative studies are warranted to evaluate whether HT efficacy differs between both techniques, with emphasis on tumor location. PMID- 30303407 TI - Tolmetin sodium-loaded thermosensitive mucoadhesive liquid suppositories for rectal delivery; strategy to overcome oral delivery drawbacks. AB - Tolmetin sodium (TS) is a nonsteroidal anti-inflammatory drug (NSAID) indicated for treatment of musculoskeletal issues. As other NSAID, TS displays a marked side effects on the gastro-intestinal (GI) tract after oral administration. Traditional solid suppositories can cause pain and discomfort for patients, may reach the end of the colon; consequently, the drug can undergo the first-pass effect. TS liquid suppository (TS-LS) was developed to enhance patient compliance and rectal mucosal safety in high-risk patients receiving highly NSAID therapy. This work was conducted to optimize and evaluate Poloxamer P407/P188-based thermoresponsive TS-LS by using mucoadhesive polymers such as methylcellulose (MC). TS-LS was prepared by cold method and characterized their in vitro physicochemical properties as gelation temperature (GT), gel strength, bioadhesive properties, and in vitro release. The safety of the prepared suppository on rectum, stomach, and liver was evaluated histologically. Pharmacokinetic analyses were performed to compare rectal TS-LS to orally Rhumtol(r) capsules. The results showed that the optimized TS-LS; composed of P407/P188/MC (21/9/0.5% w/w) displayed gelation at rectum temperature ~32.90 degrees C, gel strength of 21.35 s and rectal retention force at the administration site of 24.25 * 102 dyne/cm2. Moreover, TS-LS did not cause any morphological damage to the rectal tissues. Pharmacokinetic parameters of optimized TS-LS formulation revealed 4.6 fold increase in bioavailability as compared to Rhumtol(r) capsules. Taken together, the results demonstrated that liquid suppository is a potential and physically safe rectal delivery carrier for improvement rectal bioavailability and in vivo safety of TS. PMID- 30303408 TI - Development and Preliminary Validation of the Lung Transplant Quality of Life (LT QOL) Survey. AB - INTRODUCTION: Although lung transplantation aims to improve health-related quality of life (HRQL), existing instruments fail to include health domains considered important in this population. We aimed to develop a comprehensive lung transplant-specific instrument to address this shortcoming. METHODS: We developed a pool of 126 candidate items addressing domains previously identified as important by lung transplant recipients. Through cognitive interviews conducted in 43 transplant recipients, items deemed irrelevant or redundant were dropped. The 84 remaining items were field tested in lung transplant recipients. Exploratory and confirmatory factor analyses (CFA) were used to evaluate the factor structure and scales were evaluated for internal consistency and construct validity. RESULTS: The 84-item preliminary survey was administered to 201 lung transplant recipients with a mean age of 57.9 +/-12.7 years; 46% were female. After factor analyses and internal consistency evaluation, we retained 60 items comprising the Lung Transplant Quality of Life (LT-QOL) Survey. The LT-QOL contains ten scales that measure symptoms, health perceptions, functioning, and well-being. The CFA model had good approximate fit (comparative fit index =0.990; standardized root-mean-square residual =0.062). Cronbach alphas for the ten scales ranged from 0.75 to 0.95. Inter-scale correlations were consistent with hypothesized relationships. Subjects with severe chronic lung allograft dysfunction (CLAD; n=13) reported significantly worse HRQL than subjects without CLAD (n=168) on six of the ten LT-QOL scales. CONCLUSION: The LT-QOL is a new multidimensional instrument that characterizes and quantifies health-related quality of life in lung transplant recipients. PMID- 30303409 TI - Risk of high blood pressure associated with objective insomnia and self-reported insomnia complaints in major depression: A study on 703 individuals. AB - BACKGROUND: Since few studies have investigated the risk of high blood pressure associated with objective insomnia and self-reported insomnia complaints in major depression, the aim of this study was to examine this risk in a large sample of individuals with major depression. METHODS: Data from 703 individuals with major depression recruited from the research database of the sleep laboratory of the Erasme Hospital were analysed. High blood pressure status was defined by the presence of one of the following: self-reports at interview of either a physician diagnosis or taking antihypertensive medication; or an average systolic blood pressure >=140 mmHg or an average diastolic blood pressure >=90 mmHg during at least two medical examinations. Logistic regression analyses were conducted to examine the risk of high blood pressure associated with objective insomnia and self-reported insomnia complaints in major depression. RESULTS: After adjustment for major confounding factors associated with high blood pressure, multivariate logistic regression analysis revealed that severe objective insomnia, low complaints of repeated nighttime awakenings or early morning awakening, and intermediate or low self-reported insomnia complaints were significant risk factors of high blood pressure in major depression. CONCLUSION: In major depression, severe objective insomnia and lower self-reported insomnia complaints are associated with higher risk of high blood pressure, which justifies a better management of objective insomnia and a better assessment of insomnia complaints in this particular subpopulation to avoid the negative consequences related to the co-occurrence of high blood pressure and major depression.

PMID- 30303411 TI - Learning (by) osmosis: an approach to teaching osmolarity and tonicity. AB - Understanding osmolarity and tonicity is one of the more challenging endeavors undertaken by students of the natural sciences. We asked students who completed a course in animal physiology to submit an essay explaining what they found most perplexing about this subject, and what in-class activities proved most useful to them. Students had difficulty distinguishing osmolarity from tonicity and determining tonicity based on the solution's composition. The most useful activities were questions requiring simultaneous consideration of both osmolarity and tonicity. Problems that require calculating osmotic concentration and the volumes of body fluid compartments after administration or loss of various solutions emphasize the significance of osmolarity and tonicity in the context of systemic homeostasis and clinical medicine. We hope that our approach to teaching osmolarity and tonicity will prove useful to physiology lecturers who are looking for new ways of introducing this complicated topic to their health professions students. PMID- 30303410 TI - An analysis of the survival impact of dexmedetomidine in children undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy. AB - OBJECTIVE: Recent evidence suggests the alpha2-adrenoreceptor agonist dexmedetomidine may promote metastasis of cancer cells. In this study we sought to evaluate the impact of dexmedetomidine administration on the survival of children and adolescents with cancer. DESIGN: Retrospective chart review. SETTING: Comprehensive cancer center. PATIENTS: Children and adolescents who had undergone cytoreductive surgery with hyperthermic intraperitoneal chemotherapy for peritoneal carcinomatosis. INTERVENTION: Intraoperative and/or early postoperative (within 24 hours of surgery) administration of dexmedetomidine. MEASUREMENTS: Multivariable cox proportional hazard models were used to assess the association between dexmedetomidine administration and progression free survival (PFS) or overall survival (OS). MAIN RESULTS: Ninety-three patients were identified. The median age was 12 years, 42% were female, and 35% received dexmedetomidine. There were no significant differences between the baseline and perioperative characteristics of patients who received dexmedetomidine and those who did not. In the multivariable analysis, the administration of dexmedetomidine was not associated with PFS (HR = 1.20, 95% CI [0.60-2.41], p = .606) or OS (HR = 0.81, 95% CI [0.35-1.85], p = .611). CONCLUSION: In this retrospective study of children and adolescents who had undergone a major oncologic surgery, the intraoperative and/or early postoperative administration of dexmedetomidine was not associated with survival. PMID- 30303412 TI - Impact of an early clinical exposure project conducted by senior clinical students compared between participating and nonparticipating students. AB - An early clinical exposure project conducted by clinical students aimed to promote direct clinical experience to preclinical students. The aim of this study was to determine the effects of the project on academic achievement and study attitudes and habits between participating and nonparticipating students before ( test 1) and after the project ( test 2) in the second preclinical year and at the end of the first semester of the first clinical year ( test 3), with a subgroup analysis of the first (lowest) to third (highest) tertile of the score. Questionnaires were sent to the first clinical year students at test 3 and asked the information retrospectively at test 1 and test 2 in second year preclinical and currently at test 3, with 83.86% (265/316) being returned. Mean percentile of scores was higher at test 2 compared with test 1 in the first tertile group of participating students. Motivation to study medicine (motivation), realization of application of preclinical knowledge to clinical study (application), understanding of clinical environment (environment), and lesson review after class (review) were higher for participating than nonparticipating students at test 2 and/or test 3. Searching additional study information was higher at test 2 compared with test 1 only for participating students. This project could effectively promote application, motivation, environment, and review for participating vs. nonparticipating students at test 2 and/or test 3. Effortless, intimate, and effective communication between clinical and preclinical students and a direct experience in early clinical exposure might be key success factors.

PMID- 30303414 TI - Student engagement in a Human Anatomy and Physiology course: a New Zealand perspective. AB - The population diversity of New Zealand is due to the unique fusion of indigenous peoples of Polynesian origin (Maori), western European colonization (Pakeha), and more recent (20th century) immigration from the Pacific region (Pasifika). However, disparities in tertiary education indicate that Maori and Pasifika students are more likely to drop out during their first year of study and are less likely to complete their qualification than their Pakeha peers. Higher levels of course engagement may increase first-year grades, elevate academic performance, and encourage persistence between the first and second years of study. Therefore, a Student Course Engagement Questionnaire was used to quantify engagement in a compulsory first-year undergraduate Human Anatomy and Physiology course in a New Zealand university. A data mining technique was used to assign students into a low-engagement/low-achievement cluster, and a high engagement/high-achievement cluster. The skills, emotional, and participation interaction components of engagement were lower in Pasifika students: these students' academic grade was lower than those of both Maori and Pakeha students. The strongest predictors of cluster membership were skills engagement and emotional engagement, suggesting that these components outweighed other aspects of course engagement. Maori and Pasifika students were overrepresented in the low engagement/low-achievement cluster, and underrepresented in the high engagement/high-achievement cluster. We suggest that embedding study skills within course delivery, and constantly emphasizing their importance, would likely increase student course engagement. Also, we report that both Maori and Pasifika students remain more disengaged than their Pakeha peers. PMID- 30303415 TI - The effect of air pockets in the urinary bladder on the temperature distribution during loco-regional hyperthermia treatment of bladder cancer patients. AB - PURPOSE: Loco-regional hyperthermia combined with mitomycin C is used for treatment of nonmuscle invasive bladder cancer (NMIBC). Air pockets may be present in the bladder during treatment. The aim of this study is to quantify the effect of air pockets on the thermal dose of the bladder. METHODS: We analysed 16 patients treated for NMIBC. Loco-regional hyperthermia was performed with the in house developed 70 MHz AMC-4 hyperthermia device. We simulated treatments with the clinically applied device settings using Plan2Heat (developed in-house) including the air pockets delineated on CT scans made following treatment, and with the same volume filled with urine. Temperature distributions simulated with and without air pockets were compared. RESULTS: The average air and fluid volumes in the bladder were 6.0 ml (range 0.8 - 19.3 ml) and 183 ml (range 47-322 ml), respectively. The effect of these air pockets varied strongly between patients. Averaged over all patients, the median bladder wall temperature (T50) remained unchanged when an air pocket was present. Temperature changes exceeded +/-0.2 degrees C in, on average, 23% of the bladder wall volume (range 1.3-59%), in 6.0% (range 0.6-20%) changes exceeded +/-0.5 degrees C and in 3.2% (range 0.0-7.4%) changes exceeded +/-1.0 degrees C. There was no correlation between the differences in temperature and the air pocket or bladder volume. There was a positive correlation between air pocket surface and temperature heterogeneity. CONCLUSION: Presence of air causes more heterogeneous bladder wall temperatures and lower T90, particularly for larger air pockets. The size of air pockets must therefore be minimized during bladder hyperthermia treatments. PMID- 30303416 TI - Differences in serum IL-6 response after 1 degrees C rise in core body temperature in individuals with spinal cord injury and cervical spinal cord injury during local heat stress. AB - OBJECTIVES: Passive rise in core body temperature achieved by head-out hot water immersion (HHWI) results in acute increases in serum interleukin (IL)-6 but no change in plasma adrenaline in patients with cervical spinal cord injury (CSCI). The purpose of the present study was to determine the mechanism of heat stress induced increase in serum IL-6. SETTING: A cross-sectional study. METHODS: The study subjects were nine with CSCI, ten with thoracic and lumbar spinal cord injury (TLSCI) and eight able-bodied (AB) subjects. Time since injury was 16.1 +/ 3.4 years in TLSCI and 16.4 +/- 4.1 years in CSCI. Subjects were subjected to lower-body heat stress (LBH) by wearing a hot water-perfused suit until 1 degrees C increase in core temperature. The levels of serum IL-6, plasma adrenaline, tumour necrosis factor (TNF)-alpha, C-reactive protein (CRP), and counts of blood cells were measured at normothermia and after LBH. RESULTS: Serum IL-6 concentrations increased significantly immediately after LBH in all the three groups. DeltaIL-6% was lower in CSCI subjects compared with AB subjects. Plasma adrenaline concentrations significantly increased after LBH in AB and TLSCI subjects, but did not change throughout the study in CSCI subjects. Cardiac output and heart rate increased at the end of LBH in all three groups. CONCLUSIONS: Under a similar increase in core temperature, DeltaIL-6% was lower in the CSCI group compared with the AB group. These findings suggest that the observed rise in IL-6 during hyperthermia is mediated, at least in part, by plasma adrenaline. PMID- 30303417 TI - Psychometric validation of team experiences questionnaire in preregistration Chinese health and social care students in Hong Kong. AB - The complexity of patients' healthcare needs can be addressed more adequately by professionals working as a healthcare team. In view of this, it is important to prepare students for collaborative work when they become professionals through a students' team training at the preregistration level. As intervention programs are implemented to promote students' collaboration, instruments like Team Experiences Questionnaire (TEQ) are needed. In this connection, this study which involved 335 Chinese students enrolled in eight health and social care programs from two universities in Hong Kong investigated the factor structures of the TEQ using construct validation approach. Using confirmatory factor analysis, we examined the fit of three competing models: unidimensional model, first-order correlated model, and second-order hierarchical model. The results demonstrated that the second-order hierarchical model obtained the best fit, with a higher order construct called total team experiences subsuming the following first order factors: overall satisfaction with team experiences, team impact on quality of learning, satisfaction with team evaluation, team impact on clinical reasoning ability, and professional development. The "total team experience" construct explained from 21.1% to 35.7% of the variance in predicting students' future perception of team competency and autonomy, perceived need for cooperation, and perception of actual cooperation. Results support the applicability of the TEQ second-order hierarchical model. Implications are discussed. PMID- 30303418 TI - Process design and optimization of bioethanol production from cassava bagasse using statistical design and genetic algorithm. AB - Bioethanol production from agro-industrial residues is gaining attention because of the limited production of starch grains and sugarcane, and food-fuel conflict. The aim of the present study is to maximize the bioethanol production using cassava bagasse as a feedstock. Enzymatic liquefaction, by alpha-amylase, followed by simultaneous saccharification and fermentation (SSF), using glucoamylase and Zymomonas mobilis MTCC 2427, was investigated for bioethanol production from cassava bagasse. The factors influencing ethanol production process were identified and screened for significant factors using Plackett Burman design. The significant factors (cassava bagasse concentration (10-50 g/L), concentration of alpha-amylase (5-25% (v/v), and temperature of fermentation (27-37 degrees C)) were optimized by employing Box-Behnken design and genetic algorithm. The maximum ethanol concentrations of 25.594 g/L and 25.910 g/L were obtained from Box-Behnken design and genetic algorithm, respectively, under optimum conditions. Thus, the study provides valuable insights in utilizing the cost-effective industrial residue, cassava bagasse, for the bioethanol production. PMID- 30303419 TI - Comparison of effectiveness of epidural analgesia and monitored anesthesia care for high-intensity focused ultrasound treatment of adenomyosis. AB - BACKGROUND: High-intensity focused ultrasound (HIFU) is a noninvasive thermodestructive procedure targeting internal organs with concentrated sonification energy that may cause pain. We aimed to compare the effectiveness of epidural analgesia (EA) and monitored anesthesia care (MAC) in HIFU treatment of uterine adenomyosis. MATERIALS AND METHODS: Sixty-eight patients were included in this case-control study. Thirty-seven patients underwent MAC; 31 patients underwent fluoroscope-guided epidural analgesia. The primary outcome was a frequency of patients reporting severe or very severe intraoperative pain. Secondary outcomes were differences in dosages of analgesics, ablation ratio, and other clinical factors. RESULTS: The EA group reported a significantly lower frequency of severe or very severe intraoperative pain than did the MAC group (41.9% vs. 75.7%; p = .006). Consumption of remifentanil during treatment was significantly lower in the EA group (173 +/- 189 ug vs. 426 +/- 380 ug; p = .001), as was the use of fentanyl in the recovery room (52 +/- 38 ug vs. 75 +/- 44 ug; p = .030). Multivariable analysis revealed EA to be the largest contributing factor to increased nonperfused volume ratio (B = 0.41; 95% confidence interval = 0.29 to 0.53; p < .001). The frequency of thermal injury after HIFU was significantly lower in the EA group (22.6% vs. 54.1%; p = .008). CONCLUSIONS: EA during HIFU treatment of uterine adenomyosis improved quality of pain control and ablation ratio over MAC without increasing risk of treatment related complications. EA also reduced consumption of opioid analgesics during and after HIFU treatment. PMID- 30303420 TI - Compliance and persistence with Alzheimer's disease treatment: a retrospective analysis of multiregional hospital databases in Thailand. AB - AIMS: Due to the lack of studies evaluating compliance or persistence with Alzheimer's Disease (AD) treatment outside High-Income Countries (HICs), this study aimed to assess compliance, persistence, and factors associated with non compliance and non-persistence by utilizing existing "real-world" information from multiregional hospital databases in Thailand. MATERIALS AND METHODS: Study subjects were retrospectively identified from databases of five hospitals located in different regions across Thailand. AD patients aged >=60 years who were newly prescribed with donepezil, galantamine, rivastigmine, or memantine between 2013 and 2017 were eligible for analysis. The Medication Possession Ratio (MPR) was used as a proxy for compliance, while the Kaplan-Meier survival analysis was employed to estimate persistence. Logistic and Cox regressions were used to assess determinants of non-compliance and non-persistence, adjusted for age and gender. RESULTS: Among 698 eligible patients, mean (SD) MPR was 0.83 (0.25), with 70.3% of the patients compliant to the treatment (having MPR >= 0.80). Half of the patients discontinued their treatment (having a treatment gap >30 days) within 177 days with a 1-year persistence probability of 21.1%. The patients treated in the university-affiliated hospital were more likely to be both non compliant (OR = 1.71; 95% CI = 1.21-2.42) and non-persistent (HR = 1.33; 95% CI = 1.12-1.58). In addition, non-compliance was higher for those prescribed with single AD treatment (OR = 2.52; 95% CI = 1.35-4.69), while non-persistence was higher for those unable to reimburse for AD treatment (HR = 1.34; 95% CI = 1.11 1.62). LIMITATIONS: By using retrospective databases, a difficulty in validating whether the medications are actually taken after being refilled may over-estimate the levels of compliance and persistence. Meanwhile, possible random coding errors may under-estimate the strength of association findings. CONCLUSIONS: This study reveals the situation of compliance and persistence on AD treatment for the first time outside HICs. The determinants of non-compliance and non-persistence underline key areas for improvement. PMID- 30303421 TI - Whole body heat exposure modulates acute glucose metabolism. AB - AIM: Exercise modulates glucose tolerance and homeostasis in both healthy and diabetic individuals. Heat stress is a fundamental element of exercise. The acute glycemic response and alterations in glucose clearance following whole body passive heat stress in the absence of muscle activity has yet to be examined in humans. Knowledge of this relationship may prove useful, particularly in populations with compromised glucoregulation from reduced activity. PURPOSE: To determine insulin/glucose levels before and after an acute bout of heat stress in healthy, lean individuals and examine the effects of whole body heat stress (WBHS) and exercise on acute glucose tolerance in an expanded cohort. METHODS: Ten subjects (24.1 +/- 0.7 years) participated in a randomized control/WBHS session (up to 30 minutes at 73 degrees C) with fasting glucose (FG) and insulin drawn at baseline, immediately after and 30 minutes post heat stress. In the follow-up experiment, 20 anthropometrically diverse subjects (24.6 +/- 2.1 years) underwent an oral glucose tolerance test (OGTT) under the conditions above. RESULTS: FG levels rose 10% immediately following heat stress (8.6 (+/-5.6) mg/dl, p < .01) and returned to near baseline levels 30 minutes following WBHS. Insulin release showed its greatest increase at 30 minutes post WBHS (2.7 +/- 3.5) uU/ml p < .05). WBHS resulted in a decrease in glucose uptake [AUC increased 8.2% (1430.6 +/- 1957.03) mg/dl (p = .005)], particularly in nonlean individuals. CONCLUSION: WBHS modulates physiologic markers of metabolism. An acute bout of WBHS increases glucose and insulin levels in healthy individual and decreases glucose uptake in response to a glucose challenge, particularly those who are non lean.

AB - PURPOSE: To evaluate the incidence and risk factors of post-intravitreal injection (IVI) endophthalmitis in a single center modified operating room (OR) setting. METHODS: In a retrospective chart review study, patients who underwent IVI in a modified OR between September 2014 and November 2016 were included. Cases of post-IVI endophthalmitis were identified from the Hospital Infection Control Committee records, which tracks all post-procedure infections. RESULTS: 51 472 IVIs (37 814 patients) including 13 658 bilateral simultaneous injections were performed during the study period. There were 17 cases of endophthalmitis (0.033%, 95% CI 0.019%-0.052%). There were no cases of bilateral endophthalmitis. Age, sex, indication for IVI, simultaneous bilateral injections, number of previous injections, and type of injected drug were not significantly associated with incidence of endophthalmitis. CONCLUSION: Post-IVI endophthalmitis is rare in this modified OR setting. Simultaneous bilateral IVIs and on-site preparation of injections are safe under these conditions.

AB - Synapses are the functional units of the nervous system, and their number and protein composition undergo changes over a wide time scale. These synaptic changes manifest into differential behavioural outputs and, in turn, changes in the external conditions to the individual may elicit changes in synapses. We review here publications appeared during the last 10 years in which advances on molecular and cellular mechanisms for synapse changes have been reported. We focus on synaptic changes occurring in the time range of minutes to hours, mainly. PMID- 30303425 TI - Feasibility of targeting canine soft tissue sarcoma with MR-guided high-intensity focused ultrasound. AB - PURPOSE: Magnetic resonance imaging-guided high-intensity-focused ultrasound (MR HIFU) is a non-invasive treatment modality that precisely focuses ultrasound energy within a tumour and can be customised to result in a wide range of local bioeffects. The purpose of this study was to determine the feasibility of using MR-HIFU to treat soft tissue sarcoma (STS) in dogs. MATERIALS AND METHODS: Medical records of dogs admitted to the Virginia-Maryland College of Veterinary Medicine from 1 January 2012 to 31 December 2016 were searched for a diagnosis of sarcoma with available cross-sectional imaging of the tumour (MRI or CT). Fifty three (53) dogs were eligible for inclusion. Tumor tissue (in bone as well as in soft tissue) was considered targetable unless: (1) the ultrasound path was completely obstructed by bone or gas and (2) the MR-HIFU target was within the spinal cord or less than 1 cm from the margin of the spinal cord. Tumors were categorised as <50% targetable, >=50% targetable or non-targetable. RESULTS: Eighty-one percent of STS (81.1%, 43/53) were targetable. The head/spine tumour sites had the highest proportion of non-targetable tumours (36%, 9/25). The majority of truncal and axillary tumours were >=50% targetable (88.9%, 16/18) ,and all extremity tumours were considered >=50% targetable (100%, 5/5). CONCLUSIONS: The majority of STS were targetable. This is the first study to evaluate MR-HIFU targetability of canine STS. HIFU has potential as a therapeutic modality for treating STS in dogs, and this veterinary application is a possible model for treatment of naturally occurring STS in humans. PMID- 30303426 TI - Supporting health system transformation through an interprofessional education experience focused on population health. AB - The purpose of the study was to determine the impact of an interprofessional education (IPE) experience on first year students across all schools of a health sciences center on the topic of pediatric immunizations. The authors conducted a pre-/post-test at Louisiana State University Health Sciences Center-New Orleans with 731 first year students from 25 academic programs encompassing all six schools (Allied Health, Dentistry, Graduate Studies, Medicine, Nursing and Public Health). In the four questions related to the Interprofessional Education Collaborative (IPEC) sub-competencies and the three questions related to professional role regarding immunizations, there was a statistically significant difference in the pre-/post-test survey results (P < 0.0001). Student learning related to the collaboration needed to make a larger impact on patient outcomes was demonstrated through assessment of an open-ended question. IPE experiences can improve first-year students' perceptions of IPEC sub-competencies regarding the importance of population health and teamwork. By utilizing a population health focus with IPE activities, novice learners are equipped to learn and apply collaborative practice skills along with recognizing the importance of promoting overall health and well-being instead of just health care. PMID- 30303427 TI - A Prospective, Single-Blind, Randomized, Phase III Study to Evaluate the Safety and Efficacy of Fibrin Sealant Grifols as an Adjunct to Hemostasis During Soft Tissue Open Surgery. AB - BACKGROUND/PURPOSE: Rapid hemostasis, an essential prerequisite of good surgical practice during surgical bleeding, including soft tissue open surgery, often requires adjunctive treatment. We evaluated the safety and hemostatic effectiveness of a human plasma-derived fibrin sealant (FS Grifols) in soft tissue open surgery. METHODS: Patients with moderate soft tissue bleeding during open, urologic, gynecologic or general surgery were studied. The trial consisted of a preliminary phase (to familiarize investigators with the technique for FS Grifols application and the intraoperative procedures required by the clinical protocol) and a primary phase: in both phases, patients were randomized 1:1 to FS Grifols or Surgicel(r). The primary efficacy endpoint, based on analysis of subjects in the primary phase of the study, was to evaluate whether FS Grifols was non-inferior to Surgicel(r) in achieving hemostasis, based on the proportion of subjects in both treatment groups who achieved hemostasis at the target bleeding site (TBS) by 4 min (T4) following the start of treatment application. Safety assessments included adverse events (AEs), vital signs, physical assessments, common clinical laboratory tests, viral markers, and immunogenicity. RESULTS: A total of 224 subjects were randomized (primary phase): FS Grifols (N = 116), Surgicel(r) (N = 108). The 95% CI at T4 for the ratio of the proportion of patients achieving hemostasis in the two treatment groups was 1.064 (0.934, 1.213), indicating non-inferiority for FS Grifols vs. Surgicel(r). The rate of hemostasis at the TBS by T4 in both phases of the study was higher in the FS Grifols treatment group (preliminary phase: 90.2%; primary phase: 82.8%) than in the Surgicel(r) treatment group (preliminary phase: 78.8%; primary phase: 77.8%). Overall, reported AEs were as expected in surgical patients and were similar between the two treatment groups. CONCLUSIONS: This study shows the non inferiority in time to hemostasis of FS Grifols vs. Surgicel as an adjunct to hemostasis in patients undergoing soft tissue open surgery, and a similar rate of AEs.

AB - Interprofessional collaboration (IPC) between health professionals, and educators is an essential component of academic success and well-being for children who experience chronic illnesses. This study sought to understand parents' roles in and perceptions of IPC between their child's healthcare professionals and educators. We recruited 23 mothers to participate in our study. Data were analyzed using a combination of univariate analyses and content analysis. Overall, parents reported that they could effectively communicate their child's health and educational needs with health and educational professionals, but statistical analysis determined moderately increased challenges presenting information across professions. Most participants (n = 19) indicated that IPC between health and educational professionals could be improved. Effectively engaging parents as partners in IPC can promote more seamless collaboration and communication of a child's needs and offer a greater likelihood of achieving a child's health and educational goals.

PMID- 30303430 TI - Vergence Profile and Prevalance of Non-Strabismic Vergence Anomalies Among School Children in Abia State, Nigeria. AB - PURPOSE: To determine the prevalence of non-strabismic vergence anomalies and their relationship with age, gender, and school level in children aged 10-16 years Method: A cross-sectional study was conducted among 537 children (255 male, 282 females; mean age 13.0 +/- 2.0, years) selected from nine schools using stratified, cluster, and random sampling. The participants completed a Convergence Insufficiency Symptom Survey (CISS) and eye examinations, including the measurement of visual acuity, non-cycloplegic refraction, cover test, near point of convergence, fusional vergences, accommodative functions, and ocular health evaluation. All binocular tests were performed following the subjective refraction with the corrective lenses in place, if prescribed. RESULTS: The prevalence of low suspect, high suspect, and definite convergence insufficiency was 9.6%, 5.8%, and 4.1%, respectively. Other prevalence estimates included convergence excess (2.9%), fusional vergence dysfunction (2.6%), basic exophoria (1.7%), basic esophoria (2.8%), divergence insufficiency (0.8%), and divergence excess (0.6%). The prevalence of high suspect (p < 0.01) and definite (p < 0.01) convergence insufficiency was significantly higher in older than younger children, and as expected, in secondary more so than primary school children (p = 0.01). There was no statically significant association between gender and various vergence anomalies. CONCLUSION: The study showed that vergence anomalies are common vision conditions among Abia State school children. Given the importance of visual skills in learning and academic achievements, there is a need to develop screening and management strategies that will target those visual conditions to prevent educational and social progress being affected.

AB - OBJECTIVE: Laser with 532-nm wavelength (GreenLightTM) is clinically approved to treat benign prostatic hyperplasia (BPH). However, low rate of tissue ablation and excessive thermal coagulation are shortcomings of this therapy. The goal of this study was to use a mathematical model to identify clinically viable laser settings that have the potential to improve treatment time and outcomes. METHODS: A three-dimensional transient computational model was developed, validated against analytical and experimental results, and utilized to investigate the response of tissues subjected to continuous-wave and pulsed lasers emitting 532 nm light (GreenLightTM laser). The impact of laser power (10-125 W), pulse duration (100 ns and 100 us) and pulse frequency (10 and 100 Hz) on tissue ablation and coagulation rates and sizes was explored. RESULTS: Good agreement between the computational model and analytical and experimental results was found. Continuous-wave laser results in 13% less coagulation zone thickness and 10% higher ablation rate than the low frequency pulsed laser. With increasing laser power; ablation rate is expected to increase linearly, while coagulation zone thickness is expected to increase asymptotically. Pulse frequency influence on tissue ablation and coagulation is relevant at high power, but pulse duration is found to have minimal effect at all powers. CONCLUSIONS: Laser thermal tissue ablation employing continuous wave mode lasers outperforms that employing pulsed mode lasers. Laser power settings should be carefully selected to maximize the rate of tissue ablation and minimize tissue coagulation. PMID- 30303433 TI - Multivariate analysis as a method to understand variability in a complex excipient, and its contribution to formulation performance. AB - A key part of the Risk Assessment of excipients is to understand how raw material variability could (or does) contribute to differences in performance of the drug product. Here we demonstrate an approach which achieves the necessary understanding for a complex, functional, excipient. Multivariate analysis (MVA) of the certificates of analysis of an ethylcellulose aqueous dispersion (Surelease) formulation revealed low overall variability of the properties of the systems. Review of the scores plot to highlight batches manufactured using the same ethylcellulose raw material in the formulation, indicated that these batches tend to be more closely related than other randomly selected batches. This variability could result in potential differences in the quality of drug product lots made from these batches. Manufacture of a model drug product from Surelease batches coated using different lots of starting material revealed small differences in the release of a model drug, which could be detected by certain model dependent dissolution modeling techniques, but they were not observed when using model-independent techniques. This illustrates that the techniques are suitable for detecting and understanding excipient variability, but that, in this case, the product was still robust. PMID- 30303432 TI - Changes in serum thyroglobulin and antithyroglobulin shortly following high intensity focused ablation of benign thyroid nodules in patients with positive antithyroglobulin status. AB - BACKGROUND: We aimed to describe changes in serum thyroglobulin (Tg) and anti-Tg autoantibody shortly following high-intensity focused ultrasound (HIFU) ablation in patients with positive anti-Tg status by comparing them with patients with negative anti-Tg and to correlate them with 6-month nodule shrinkage and treatment success. METHODS: From 2015 to 2017, patients who underwent HIFU ablation of a benign thyroid nodule were analysed. Serum Tg and anti-Tg were checked on treatment day (baseline) and 4 days after treatment. Anti-Tg >99 IU/ml were considered positivity. Percentage Tg or anti-Tg change = [Level on Day-4 - baseline level]/[Baseline level] * 100 while nodule shrinkage was measured by volume reduction ratio (VRR) = [Baseline volume - volume at 6 month]/[Baseline volume] * 100. Treatment success was defined as VRR >50%. RESULTS: Among the 276 eligible patients, 85 (30.8%) patients were positive for anti-Tg (Group I) while the others (n = 191, 69.2%) were negative (Group II). Relative to group II, Group I had a less significant Tg rise on Day 4 (4121.78 +/- 9321.90% vs. 5711.53 +/- 23487.20%, p = .013). There was a fall in anti-Tg on day 4 for group I (-11.56 +/ 139.69%). This percentage anti-Tg drop significantly correlated with the 6-month VRR (rho = -0.602, p = .030) but was not a significant factor of treatment success. CONCLUSIONS: Given the fact that the percentage anti-Tg drop correlated significantly with 6-month nodule shrinkage in group I, monitoring early anti-Tg change may help to predict the 6-month nodule shrinkage in patients with positive anti-Tg. PMID- 30303434 TI - Modulation of neuromuscular synapses and contraction in Drosophila 3rd instar larvae. AB - Over the past four decades, Drosophila melanogaster has become an increasingly important model system for studying the modulation of chemical synapses and muscle contraction by cotransmitters and neurohormones. This review describes how advantages provided by Drosophila have been utilized to investigate synaptic modulation, and it discusses key findings from investigations of cotransmitters and neurohormones that act on body wall muscles of 3rd instar Drosophila larvae. These studies have contributed much to our understanding of how neuromuscular systems are modulated by neuropeptides and biogenic amines, but there are still gaps in relating these peripheral modulatory effects to behavior. PMID- 30303435 TI - Clinical Characteristics and Treatment of 308 Panuveitis Patients over 10 Years: Results from the KKESH Uveitis Survey Study Group. AB - PURPOSE: To describe the clinical characteristics and surgical outcomes of panuveitis over a 10-year period. METHODS: Data were collected on panuveitis etiology, treatment, surgery and change in vision. RESULTS: Overall, 308 patients (594 eyes) were evaluated, 54.9% with non-granulomatous and 45.1% with granulomatous uveitis. Fifty-four patients had infectious and 254 had non infectious uveitis. In infectious panuveitis, vision remained unchanged at last visit. The most frequent diagnosis was presumed intraocular tuberculosis (PIOTB) uveitis (48.1%). In the non-infectious subgroup vision increased significantly by 2 lines at last visit (p = 0.020). The most common diagnose was Vogt-Koyanagi Harada (VKH) disease (38.6%). Initial therapy was oral prednisone in 86.6% with non-infectious etiology followed by immunosuppressive agents. Surgery secondary to complications (mainly cataracts) was performed in 46.7% patients. CONCLUSION: In Saudi Arabia, panuveitis was mainly due to VHK. PIOTB was the most common etiology for infectious panuveitis. Immunosuppressive therapy and surgery maintained BCVA in non-infectious panuveitis. PMID- 30303436 TI - Coadministration of 13-valent pneumococcal conjugate and quadrivalent inactivated influenza vaccines in adults previously immunized with polysaccharide pneumococcal vaccine 23: a randomized clinical trial. AB - Immune responses to 13-valent pneumococcal conjugate vaccine (PCV13) and quadrivalent inactivated influenza vaccine (QIV) in older adults may vary with coadministration and previous pneumococcal polysaccharide vaccination. This study assessed safety and noninferiority of immune responses to coadministered PCV13 and QIV compared with each vaccine given alone. Adults >=50 years old preimmunized with >=1 dose of 23-valent pneumococcal polysaccharide vaccine (PPSV23) >=1 year before enrollment were randomized 1:1 to receive PCV13+QIV then placebo 1 month later or placebo+QIV then PCV13 1 month later. Administration of PCV13 and placebo was blinded; QIV was administered open-label. Pneumococcal serotype-specific opsonophagocytic activity (OPA) geometric mean titers (GMTs) 1 month after PCV13, and influenza hemagglutination inhibition assay GMTs 1 month after QIV were measured. Prespecified noninferiority was demonstrated by a lower bound of the 2-sided 95% CI for geometric mean ratios >0.5. Safety endpoints included proportions of subjects with adverse and serious adverse events. Of 882 randomized subjects, 846 comprised the evaluable immunogenicity population. Immune responses to all 13 pneumococcal serotypes and all 4 influenza strains 1 month after PCV13+QIV were noninferior to responses 1 month after each vaccine given alone. No safety concerns were identified. Immune responses to coadministered PCV13 and QIV were noninferior to responses after each vaccine given alone, although generally lower for coadministered PCV13. PCV13 and QIV can be administered concomitantly to adults >=50 years of age preimmunized with PPSV23. PMID- 30303437 TI - A molecular dynamics approach towards evaluating osmotic and thermal stress in the extracellular environment. AB - OBJECTIVE: A molecular dynamics approach to understanding fundamental mechanisms of combined thermal and osmotic stress induced by thermochemical ablation (TCA) is presented. METHODS: Structural models of fibronectin and fibronectin bound to its integrin receptor provide idealized models for the effects of thermal and osmotic stress in the extracellular matrix. Fibronectin binding to integrin is known to facilitate cell survival. The extracellular environment produced by TCA at the lesion boundary was modelled at 37 degrees C and 43 degrees C with added sodium chloride (NaCl) concentrations (0, 40, 80, 160, and 320 mM). Atomistic simulations of solvated proteins were performed using the GROMOS96 force field and TIP3P water model. Computational results were compared with the results of viability studies of human hepatocellular carcinoma (HCC) cell lines HepG2 and Hep3B under matching thermal and osmotic experimental conditions. RESULTS: Cell viability was inversely correlated with hyperthermal and hyperosmotic stresses. Added NaCl concentrations were correlated with a root mean square fluctuation increase of the fibronectin arginylglycylaspartic acid (RGD) binding domain. Computed interaction coefficients demonstrate preferential hydration of the protein model and are correlated with salt-induced strengthening of hydrophobic interactions. Under the combined hyperthermal and hyperosmotic stress conditions (43 degrees C and 320 mM added NaCl), the free energy change required for fibronectin binding to integrin was less favorable than that for binding under control conditions (37 degrees C and 0 mM added NaCl). CONCLUSION: Results quantify multiple measures of structural changes as a function of temperature increase and addition of NaCl to the solution. Correlations between cell viability and stability measures suggest that protein aggregates, non-functional proteins, and less favorable cell attachment conditions have a role in TCA induced cell stress. PMID- 30303438 TI - Human PXR-mediated transcriptional activation of CYP3A4 by "Fuzi" extracts. AB - OBJECTIVE: This study focused on determining whether the "Fuzi" (FZ) extracts from different extraction methods are related to pregnane X receptor (PXR) and cytochrome P450 3A4 (CYP3A4), and explore the mechanism. METHODS: FZ was extracted under various conditions, and the components were identified by Ultra Performance Liquid Chromatography/Quad Time Of Flight Mass Spectrometry (UPLC/Q TOF-MS). Annexin V-FITC and propidium iodide staining assays were used to measure the cell cytotoxicity of these extracts. Real-time PCR, western blot analysis and reporter gene assay were used to detect the expression changes of PXR and CYP3A4. RESULTS: FZ extracts were found to contain high levels of monoester-diterpene alkaloids (MDAs) and diester-diterpene alkaloids (DDAs). FZ extracts were cytotoxic. Interestingly, we found that FZ extracts and DDAs can induce the expressions of PXR and CYP3A4. And the MDAs can inhibit the expressions of PXR and CYP3A4. CONCLUSION: Different extracts of FZ can induce the expressions of PXR and CYP3A4 in different degrees. This may be related to the drug-drug interactions. PMID- 30303439 TI - Quantified water intake in laboratory cats from still, free-falling and circulating water bowls, and its effects on selected urinary parameters. AB - Objectives The study objectives were to determine if method of water presentation (still [S], circulating [C] or free-falling [FF] bowl systems) influences daily water consumption in cats in a controlled environment, and whether differences in water intake affect urine relative super saturation (RSS) for calcium oxalate and struvite, urine specific gravity (USG), urine osmolality (Uosmol) and urine volume. Methods Sixteen healthy laboratory cats fed a dry diet were individually housed with urine collection systems. Each cat underwent a randomized 2 week crossover period with all bowl systems allowing a 1 week acclimation period between each crossover. Water intake was measured daily by bowl weight, accounting for spillage and evaporation. USG and urine volume were measured daily, whereas other urinary parameters were measured at various time points throughout each 14 day crossover period. Results Fourteen cats completed the study. Average daily water intake (ml/kg/day), urine volume, USG and urine RSS for struvite and calcium oxalate were not significantly different between water bowls. Uosmol was significantly higher in C compared with S and FF bowl systems ( P = 0.009 for both). Three individual cats demonstrated a significant water bowl preference (Cat 4: C >S, P = 0.039; Cat 10: FF >C, P = 0.005; Cat 11: S >C, P = 0.037). Conclusions and relevance Overall, water bowl type had no appreciable effect on water intake. Uosmol was the only urinary parameter found to be significantly different, and was higher for the C bowl. The implication of this is unknown, considering water intake did not differ significantly between bowls. Alternative methods to increase water intake should be implemented beyond providing unique water bowls in patients where augmented water intake would be beneficial for disease management. PMID- 30303440 TI - Development of a small-scale spray-drying approach for amorphous solid dispersions (ASDs) screening in early drug development. AB - The present study details the development of a small-scale spray-drying approach for the routine screening of amorphous solid dispersions (ASDs). This strategy aims to overcome the limitations of standard screening methodologies like solvent casting and quench cooling to predict drug-polymer miscibility of spray-dried solid dispersions (SDSDs) and therefore to guarantee appropriate carrier and drug loading (DL) selection. A DoE approach was conducted to optimize process conditions of ProCept 4M8-TriX spray-drying to maximize the yield from a 100 mg batch of Itraconazole/HPMCAS-LF and Itraconazole/Soluplus 40:60 (w/w). Optimized process parameters include: inlet temperature, pump speed, drying and atomizing airflows. Identified process conditions derived from the DoE analysis were further (i) tested with Itraconazole, Naproxen and seven polymers, (ii) adapted for small cyclone use, (iii) downscaled to 20 mg batch production. Drug-polymer miscibility was systematically characterized using modulated differential scanning calorimetry (mDSC). Spray-drying was identified as a well-suited screening approach: mean yield of 10.1 to 40.6% and 51.1 to 81.0% were obtained for 20 and 100 mg ASD productions, respectively. Additionally, this work demonstrates the interest to move beyond conventional screening approaches and integrate spray-drying during screening phases so that a greater prediction accuracy in terms of SDSDs miscibility and performance can be obtained. PMID- 30303441 TI - Response to PCV13 vaccination in patients with multiple myeloma versus healthy controls. AB - Infections are a major cause of morbidity and mortality in individuals with multiple myeloma (MM). These individuals exhibit humoral dysfunction and show a suboptimal response to pneumococcal polysaccharide vaccine (PPV23). Since pneumococcal conjugate vaccine (PCV13) elicits a T cell dependent response, it is recommended in patients with multiple myeloma. This study compares the initial response to PCV13 and durability of the response at 6 months in patients with multiple myeloma versus normal controls. Seven patients with multiple myeloma and 18 control patients were enrolled in the study. Streptococcal pneumonia serotype IgG titers were drawn at baseline, day 30, and day 180 after MM patients and controls received PCV13. Although vaccination with PCV13 produced a similar initial response in patients with multiple myeloma compared to control subjects, the duration of response may have waned in patients with multiple myeloma as compared to control subjects. PMID- 30303442 TI - High Mobility Group Protein B1 (HMGB1) and Interleukin-1beta as Prognostic Biomarkers of Epilepsy in Children. AB - The present study examined whether serum biomarkers can predict the prognosis of childhood epilepsy, including seizure frequency, electroencephalographic (EEG) changes, and cognitive impairment. We measured serum concentrations of high mobility group protein B1 (HMGB1), interleukin-1beta (IL-1beta), S100 calcium binding protein B (S-100B), glial fibrillary acidic protein (GFAP), and alpha1 antichymotrypsin (AACT) in 180 children with new-onset epilepsy and 40 healthy children. Cognitive evaluations were performed 18 months after the initial seizure episodes at diagnosis (ie, baseline visit). The relationship between serum biomarkers and epilepsy prognosis was investigated using Pearson correlation coefficients, logistic regression analyses, and receiver operating characteristic curves. Sixty-seven patients had generalized tonic-clonic seizures, 92 had focal motor seizures, and 21 had epileptic spasms. Serum concentrations of HMGB1, IL-1beta, S-100B, and GFAP were significantly higher in the epilepsy group within 24 hours of a seizure episode than in the control group. Furthermore, HMGB1 and IL-1beta were significant predictors of epilepsy prognosis. Receiver operating characteristic curve analysis revealed that HMGB1 could more accurately predict seizure frequency than IL-1beta; when the serum concentration of HMGB1 was >9.625 ng/mL, there was 80.6% sensitivity and 92.5% specificity for predicting seizure frequency reduction. In conclusion, HMGB1 and IL-1beta have a predictive value for epilepsy prognosis in children. PMID- 30303443 TI - Evolution of a comprehensive, orthogonal approach to sequence variant analysis for biotherapeutics. AB - Amino acid sequence variation in protein therapeutics requires close monitoring during cell line and cell culture process development. A cross-functional team of Pfizer colleagues from the Analytical and Bioprocess Development departments worked closely together for over 6 years to formulate and communicate a practical, reliable sequence variant (SV) testing strategy with state-of-the-art techniques that did not necessitate more resources or lengthen project timelines. The final Pfizer SV screening strategy relies on next-generation sequencing (NGS) and amino acid analysis (AAA) as frontline techniques to identify mammalian cell clones with genetic mutations and recognize cell culture process media/feed conditions that induce misincorporations, respectively. Mass spectrometry (MS) based techniques had previously been used to monitor secreted therapeutic products for SVs, but we found NGS and AAA to be equally informative, faster, less cumbersome screening approaches. MS resources could then be used for other purposes, such as the in-depth characterization of product quality in the final stages of commercial-ready cell line and culture process development. Once an industry-wide challenge, sequence variation is now routinely monitored and controlled at Pfizer (and other biopharmaceutical companies) through increased awareness, dedicated cross-line efforts, smart comprehensive strategies, and advances in instrumentation/software, resulting in even higher product quality standards for biopharmaceutical products. PMID- 30303444 TI - Optimization and partial characterization of ca-independent alpha-amylase from Bacillus amyloliquefaciens BH1. AB - Strain Bacillus amyloliquefaciens BH1 was evaluated for the generation of alpha amylase. Culture conditions and medium components were optimized by a statistical approach for the optimal generation of alpha-amylase with response surface methodology (RSM) method. The Plackett-Burman (PB) design was executed to select the fermentation variables and Central composite design (CCD) for optimizing significant factors influencing production. The optimum levels for highest generation of alpha-amylase activity (198.26 +/- 3.54 U/mL) were measured. A 1.69 fold improve generation was acquired in comparison with the non-optimized. Partial characterization of the alpha-amylase indicated optimal pH and temperature at 7.0 and 40 degrees C, respectively. Crude alpha-amylase maintained a constant pH range 5.0-8.0 and 30-70 degrees C. The alpha-amylase was independent of Ca2+, and the activity was inhibited by Fe3+, Co2+, Cu2+, and Hg2+. The thermo and pH stability of the alpha-amylase indicate its extensive application in the food and pharmaceutical industries. PMID- 30303445 TI - Impact of trial design and patient heterogeneity on the identification of clinically effective therapies for progressive MS. AB - Clinically effective immunomodulatory therapies have been developed for relapsing remitting multiple sclerosis (RRMS), but they have generally not translated to a corresponding slowing of disability accumulation in progressive forms of multiple sclerosis (MS). Since disability is multifaceted, progressive patients are heterogeneous, and the drivers of disease progression are still unclear, it has been difficult to identify the most informative outcome measures for progressive trials. Historically, secondary outcome measures have focused on inflammatory measures, which contributed to the recent identification of immunomodulatory therapies benefiting younger patients with more inflammatory progressive MS. Meanwhile, agents capable of treating late-stage disease have remained elusive. Consequently, measures of neurodegeneration are becoming common. Here, we review completed clinical trials testing immunomodulatory therapies in primary progressive multiple sclerosis (PPMS) or secondary progressive multiple sclerosis (SPMS) and discuss the features contributing to trial design variability in relation to trial outcomes, and how efforts toward better patient stratification and inclusion of reliable progression markers could improve outcomes. PMID- 30303446 TI - Fungal co-culture increases ligninolytic enzyme activities: statistical optimization using response surface methodology. AB - The optimization of ligninolytic enzyme (LE) activities in a novel fungal co culture between Pycnoporus sanguineus and Beauveria brongniartii were studied using a Plackett-Burman experimental design (PBED) and a central composite design (CCD). In addition, H2O2 role was analyzed. Laccase (EC. 1.10.3.2) and MnP (EC 1.11.1.14) activities of P. sanguineus increased 6.0- and 2.3-fold, respectively, in the co-culture with B. brongniartii. The H2O2 content was higher in the co culture (0.33-7.12-fold) than in the P. sanguineus monoculture. The PBED revealed that yeast extract (YE), FeSO4, and inoculum amount were significant factors for laccase and MnP activities and H2O2 production in the co-culture, which increased by 8.2-, 5.2- and 1.03-fold, respectively. The YE and FeSO4 were studied using a CCD to optimize the studied response variables. Laccase activity was enhanced 1.5 fold by CCD, the optimal amount of YE was 0.366 g L-1. Quadratic term of FeSO4 modulated MnP activity and was associated with a 4.28-fold increase compared to the PBED. Both YE and its quadratic term significantly affected H2O2 production; however, the CCD did not enable an increase in H2O2 production. Pearson correlation indicated an increase in laccase (r2=0.4411, p = 0.0436) and MnP (r2=0.5186, p = 0.0198) activities following increases in H2O2 in the co-culture system. PMID- 30303447 TI - EEG dynamics of spontaneous stimulus-independent thoughts. AB - In this study, we aimed to compare the oscillatory dynamics accompanying self referential and non-self-referential stimulus-independent thoughts. Electroencephalograms were recorded in 30 healthy participants who were asked to press buttons classifying their spontaneous thoughts as self-referential or non self-referential. EEG data were analyzed using independent component analysis in conjunction with dipole localization. Self-referential thoughts, as compared to non-self-referential thoughts, were accompanied by more pronounced decreases of theta, alpha, and beta spectral power in the anterior hub of the default-mode network, in the left lateral prefrontal, motor/somatosensory, and temporal cortices. These oscillatory dynamics are interpreted as a reflection of autobiographical memory retrieval intrinsic to self-referential thoughts.

PMID- 30303448 TI - Accuracy of advanced CT imaging in prediction of functional outcome after endovascular treatment in patients with large-vessel occlusion. AB - Background and purpose Computed tomography perfusion (CTP) and multiphase CT angiography (mCTA) help selection for endovascular treatment (EVT) in anterior ischemic stroke (AIS). Our aim was to investigate the ability of perfusion maps and collateral score to predict functional outcome after EVT. Patients and methods Patients with M1-middle cerebral artery occlusion, evaluated by mCTA and CTP and treated with EVT within six hours of onset, were enrolled. Perfusion parametric maps of cerebral blood flow (CBF), cerebral blood volume (CBV) and time to maximum of tissue residue function ( Tmax) were generated; areas of altered perfusion were manually outlined to obtain volumes CBFv, CBVv, [Formula: see text] and [Formula: see text]. Diffusion-weighted imaging (DWI) at 24-36 hours was used to manually outline the ischemic core (volume: DWIv). Collateral vessels were assessed on mCTA considering extent and delay of maximal enhancement (six-point scale). Functional outcome was evaluated by modified Rankin Scale score at three months. Volumes in good and poor outcome groups were compared by Wilcoxon rank-sum test t, and their discriminative ability for outcome was determined by receiver operating characteristic analysis. A logistic regression model, including Tmax, CBF and collaterals, was used to differentiate good and poor outcome. Results Seventy-one patients (mean age 75 +/- 11 years, range 45-99 years) were included. [Formula: see text], [Formula: see text], CBVv, CBFv and DWIv were statistically different between the two groups. CBF had the best discriminative value for good and poor outcome (area under the curve (AUC) 0.73; 64.5% sensitivity; 74.4% specificity); the logistic regression model might be promising (AUC 0.79, 64.5% sensitivity, 82.1% specificity). Conclusions In patients with AIS, the combined use of CTP and mCTA predicts functional outcome of EVT and might allow better selection. PMID- 30303449 TI - The high expression of Aspergillus pseudoglaucus protease in Escherichia coli for hydrolysis of soy protein and milk protein. AB - The hydrolysates of soy protein and milk protein are nutritional and functional food ingredients. Aspergillus pseudoglaucus aspergillopepsin I (App) is an acidic protease, including signal peptide, propeptide, and catalytic domain. Here, we cloned the catalytic domain App with or without propeptide in Escherichia coli. The results showed that the App without propeptide was not expressed or did not exhibit activity and App with propeptide (proApp) was highly expressed with a specific activity of 903 U/mg. Moreover, the denaturation temperature of proApp was 4.1 degrees C higher than App's. The proApp showed 104 U/mg and 252 U/mg hydrolysis activities towards soy protein and milk protein under acidic conditions. By RP-HPLC analysis, the peptides obtained from the hydrolysates of soy protein and milk protein were hydrophilic peptides. This work first demonstrates efficient proteolysis of soy protein and milk protein through the functional expression of full-length proApp, which will likely have valuable industrial applications. PMID- 30303450 TI - Calcified brain metastatic adenocarcinoma: A case report and review of the literature. AB - Introduction Calcification in brain metastasis occurs rarely so it is reported in approximately 1% of surgical and 6.6% of autopsy specimens. Here we report a new case of brain metastasis with calcification. Case presentation A 44-year-old woman presented with a generalized tonic-clonic seizure with no neurological deficit on physical examination. Brain imaging demonstrated a hyperdense lesion on computed tomography scan and hyposignal and rim enhancement on T1, T2 and T1 with gadolinium injection sequence images in the right parieto-occipital lobe. Intraoperatively, there was a well-defined solid homogenous calcified mass within brain parenchyma. The lesion that resembled a meningioma was totally resected. The histopathological examination revealed metastatic adenocarcinoma. Conclusion Metastatic brain lesions should be in the differential diagnosis of a solitary calcified brain mass, although it occurs rarely. It is important to differentiate it radiologically from intralesional haemorrhage. PMID- 30303451 TI - Carboxymethyl cellulase production optimization from Glutamicibacter arilaitensis strain ALA4 and its application in lignocellulosic waste biomass saccharification. AB - In this context, carboxymethyl cellulase (CMCase) production from Glutamicibacter arilaitensis strain ALA4 was initially optimized by one factor at a time (OFAT) method using goat dung as proficient feedstock. Two-level full factorial design (25 factorial matrix) using first-order polynomial model revealed the significant (p < 0.05) influence of pH, moisture, and peptone on CMCase activity. Central composite design at N = 20 was further taken into account using a second-order polynomial equation, and thereby liberated maximum CMCase activity of 4925.56 +/- 31.61 U/g in the goat dung medium of pH 8.0 and 100% moisture containing 1% (w/w) peptone, which was approximately two fold increment with respect to OFAT method. Furthermore, the partially purified CMCase exhibited stability not only at high pH and temperature but also in the presence of varied metal ions, organic solvents, surfactants, and inhibitors with pronounced residual activities. The enzymatic hydrolysis using partially purified CMCase depicted the maximum liberation of fermentable sugars from alkali pretreated lignocellulosic wastes biomass in the order of paddy straw (13.8 +/- 0.15 mg/g) > pomegranate peel (9.1 +/- 0.18 mg/g) > sweet lime peel (8.37 +/- 0.16 mg/g), with saccharification efficiency of 62.1 +/- 0.8, 40.95 +/- 0.4, and 37.66 +/- 0.4%, respectively after 72 hr of treatment.

AB - Lymphatic filariasis is a "disease of poor people" due to a large section of affected people with economic backwardness. Therefore, successful elimination of this disease requires a cost-effective prophylactic agent such as vaccine along with conventional drugs. The Abundant Larval Transcript-2 (BmALT-2) protein of Brugia malayi has been recognized as the most potential vaccine candidate. Tuftsin, a tetra-peptide immunopotentiator has already shown the enhanced immunogenicity of various vaccine antigens in earlier studies. This study deals with the development of tuft-alt-2 fusion construct and a suitable culture condition for its large-scale production in Pichia pastoris. The recombinant P. pastoris/tuft-alt-2 with 9-11 copies of the gene construct exhibited the highest expression level. The molecular weight of P-TUFT-ALT-2 was determined as 28 kDa in SDS-PAGE including 3 kDa due to glycosylation. The dry cell biomass was 57.4 gL-1 in the bioreactor. The P-TUFT-ALT-2 expression was measured as about 35 mg L 1, which was 102% higher than flask culture. The P-TUFT-ALT-2 produced the highest 65,000 IgG peak titer in Balb/c mice. Moreover, P-TUFT-ALT-2 exhibited about 9.46% higher splenocyte proliferation than E. coli expressed E-ALT-2 alone. The enhanced secreted production of P-TUFT-ALT-2 in bioreactor would step up its commercialization as an inexpensive commercial vaccine for human lymphatic filariasis.

AB - The objective of the present study was to optimize parameters for the cultivation of Lichtheimia corymbifera (mesophilic) and Byssochlamys spectabilis (thermophilic) for the production of beta-glucosidases and to compare the catalytic and thermodynamic properties of the partially purified enzymes. The maximum amount of beta-glucosidase produced by L. corymbifera was 39 U/g dry substrate (or 3.9 U/mL), and that by B. spectabilis was 77 U/g (or 7.7 U/mL). The optimum pH and temperature were 4.5 and 55 degrees C and 4.0 and 50 degrees C for the enzyme from L. corymbifera and B. spectabilis, respectively. beta Glucosidase produced by L. corymbifera was stable at pH 4.0-7.5, whereas the enzyme from B. spectabilis was stable at pH 4.0-6.0. Regarding the thermostability, beta-glucosidase produced by B. spectabilis remained stable for 1 h at 50 degrees C, and that from L. corymbifera was active for 1 h at 45 degrees C. Determination of thermodynamic parameters confirmed the greater thermostability of the enzyme produced by the thermophilic fungus B. spectabilis, which showed higher values of DeltaH, activation energy for denaturation (Ea), and half-life t(1/2). The enzymes were stable in the presence of ethanol and were competitively inhibited by glucose. These characteristics contribute to their use in the simultaneous saccharification and fermentation of vegetable biomass.

AB - This study tested the hypothesis of the strong scholar perception of the journal Sports Biomechanics with a bibliometric analysis of top-cited articles. Three major databases, Google Scholar, Scopus and Web of Science, were searched for the most cited articles published in Sports Biomechanics for the first 15 years (2002 2016) of publication. The top 20 (4%) cited articles from each database were qualitatively analysed for research themes and descriptive statistics calculated for citations and citation rates. The top-cited articles published in Sports Biomechanics had high citation rates and included several citation classics, indicating strong contributions to the advancement of knowledge in applied biomechanics and beyond. The results support previous high ratings of the journal by sport and exercise biomechanics scholars and refute the biased and lower ranking based on the Web of Science Impact Factor. There was moderate (40-70%) agreement on the top 20 cited articles between the three databases due to differences in indexing and temporal coverage. PMID- 30303455 TI - Ecotoxicological risk assessment of contaminated soil from a complex of ceramic industries using earthworm Eisenia fetida. AB - The aim of this study was to determine ecotoxicological parameters for biomonitoring of environmental risk of native soils from a ceramic industrial area that had been contaminated with cadmium (Cd) and chromium (Cr) by using the earthworm, Eisenia fetida. Initially, lab tests were conducted to compare earthworm (Eisenia fetida) growth, survival, morphology, behavior, and reproduction rates following exposure to six concentrations of contaminated soil at 0%, 6.25%, 12.5%, 25%, 50%, or 100% mixed in artificial soil and cow dung following a 28-d incubation period. The second experiment consisted of utilizing Eisenia fetida in a predetermined lowest observed effect concentration to measure heavy metals bioaccumulation from superficial soil collected from a ceramic industrial area following a 56-d exposure. Data demonstrated that in the lab earthworms maintained at 6.25% of contaminated soil, exhibited significant increase in mean weight, bioaccumulation of Cd and Cr associated with a significant decrease in the amount of Cd and Cr in the soil. At field testing, similar results that were observed as in the lab as evidenced by rise in mean weight, higher levels of Cd and Cr in the earthworm tissue accompanied by significant fall in soil levels of Cd and Cr. In conclusion, at tested relevant environmental concentrations, the use of Eisenia fetida for assessing ecotoxicological risk arising from contaminated soil due to ceramic industrial pollutant emissions was found to be an effective tool for biomonitoring program.

AB - The objective was to evaluate the anticancer and antioxidant activities of the methanolic extracts of halophilic bacteria, isolated from soil samples of Marakkanam saltern and Pichavaram mangrove forest, India. Radical Scavenging activity, reducing power, and metal ion chelation ability was used to evaluate the antioxidant potential of the metabolic extracts, whereas cell viability was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The methanolic extract of Bacillus VITPS7 exhibited significant antioxidant property. Bacillus VITPS14 and Bacillus VITPS16 extracts were cytotoxic against HeLa cell lines but not to A549 cell lines. Colorimetric assays for the presence of specific metabolites including, total flavonoid and beta carotene content were performed. The presence of these specific classes of metabolites was confirmed by UV-Visible spectrophotometry, Nuclear Magnetic Resonance (NMR) spectroscopy and Gas Chromatography-Mass Spectrometry (GC-MS). Specific NMR signals revealed the presence of aromatic and unsaturated metabolites whereas GC-MS analysis indicated the presence of metabolites such as squalene and methyl hexadeconate. The present study thus reports for the first time the presence of squalene in Bacillus VITPS12 and Planococcus maritimus VITP21, in addition to other metabolites that contribute to the observed antioxidant or/and cytotoxicity, thus revealing the therapeutic potential of these selected halophilic bacterial isolates.

AB - Pisum sativum lectin (Psl) is a metalloprotein which is in the center of research interest because of its HIV-1 reverse transcriptase inhibitory activity and mitogenic activity. The application of this lectin in various fields demands the economically feasible and scalable purification strategy other than affinity chromatography. The suitability of aqueous two phase system (ATPS) composed of poly ethylene glycol (PEG) with different salts (sodium citrate, potassium citrate, and ammonium citrate) was evaluated for better partitioning of Psl. The significant factors such as molar mass and concentration of PEG, type and concentration of salts, the effect of tie line length (TLL), ionic strength, and pH were studied to select a suitable system for better partitioning of Psl. ATPS comprising of 18% PEG 6000, 16% sodium citrate, 1% NaCl at the operating condition of pH 8, 40.23% of TLL, and the volume ratio of 1.32 was found to be the best system which gave a maximum partition coefficient and yield of 14.5% and 98.66%, respectively. PMID- 30303459 TI - Brain magnetic resonance imaging findings in postpartum headache. AB - Objectives The objectives were to determine the frequency of abnormal magnetic resonance imaging findings in patients with postpartum headache and related factors. Methods A total of 102 patients with postpartum headache underwent brain magnetic resonance imaging study. The images were examined by a blinded radiologist. The related demographic, obstetric and headache-related factors were recorded. The multiple logistic regression model was used to determine the predictive factors. Results Abnormal magnetic resonance imaging findings were observed in 42 of 102 patients (41.2%, 95% confidence interval = 31.6 to 50.7%). The most common finding was sinusitis (10 of 42 patients, 23.8%, 95% confidence interval = 15.5 to 32%). Then, posterior reversible encephalopathy syndrome (six of 42 cases, 14.2%, 95% confidence interval = 7.4 to 20.9%), cerebral venous thrombosis (four of 42 cases, 9.5%, 95% confidence interval = 3.8 to 15.1%), and subarachnoid hemorrhage (four of 42 cases, 9.5%, 95% confidence interval = 3.8 to 15.1%) were most prevalent findings. Convulsions (odds ratio of 3.39) and initiation of headache earlier than 5 days postpartum (odds ratio of 0.29) were significant predictive factors. Conclusion Abnormal brain magnetic resonance imaging findings were seen in a considerable number of patients with postpartum headache. When headache starts in the first 5 days postpartum and accompanied by convulsions, there are likely to be abnormal magnetic resonance imaging findings. PMID- 30303458 TI - A global view of Gyroporus: molecular phylogenetics, diversity patterns, and new species. AB - Gyroporus (Gyroporaceae, Boletales) is a highly diverse genus of poroid ectomycorrhizal mushrooms with a nearly worldwide distribution. Previous attempts to unravel the diversity within this genus proved difficult due to the presence of semicryptic species and ambiguous results from analysis of ribosomal RNA markers. In this study, we employ a combined morphotaxonomic and phylogenetic approach to delimit species and elucidate geographic and evolutionary patterns in Gyroporus. For phylogenetic analyses, the protein-coding genes atp6 (mitochondrial adenosine triphosphate [ATP] synthase subunit 6) and rpb2 (nuclear second largest subunit of RNA polymerase II) were selected based on their utility in studies of Boletales. We infer several distinct clades, most notably one corresponding to G. castaneus as a speciose Northern Hemisphere group, another unifying G. cyanescens and like entities, and a third group unifying G. longicystidiatus and a New World sister species. Also notable is the recovery of a sister relationship between the cyanescens and longicystidiatus clades. We formally describe five new species of Gyroporus, outline a number of provisional species, and briefly discuss distributional patterns. This study provides an important scaffold for future work on this well-known but poorly understood genus of fungi. PMID- 30303460 TI - Trauma-Informed Care and Posttraumatic Growth Among Bereaved Youth: A Pilot Study. AB - Although a fair amount has been written about posttraumatic stress disorder among bereaved children and adolescents, less has been written about posttraumatic growth (PTG) and its predictors among this population. This study examines predictors of PTG and the impact of trauma-informed care on PTG among bereaved youth. A preexperimental, pretest-posttest design was applied to measure PTG among bereaved children ( N = 32) before and after attending a healing camp that provides trauma-informed care. A regression model was applied to examine predictors of PTG. Results showed that children participating in the camp increased their PTG scores to a statistically significant degree. Circumstance of death (sudden or expected) was a predictor in this study. The results are discussed in relation to limitations, implications for future research, and practice. PMID- 30303461 TI - Comparing Suicide Risk Factors Among Individuals with a History of Aborted, Interrupted, and Actual Suicide Attempts. AB - Recent standardized nomenclature has suggested distinctions among aborted, interrupted, and actual suicide attempts. This study examined differences in self reported symptoms among individuals with a history of aborted, interrupted, and actual suicide attempts. 167 young adults with a history of suicidality completed self-report measures of suicide attempt history and current symptoms, a clinical interview assessing past suicidal behavior, and a pain tolerance task. Only 78.8% of participants who initially reported a suicide attempt history were classified as suicide attempters following the clinical interview. Individuals who reported only aborted attempts during the clinical interview reported less severe clinical symptoms than those reporting a history of at least one actual attempt. Individuals with a history of actual suicide attempts may represent a more clinically severe group than those with a history of aborted attempts only. PMID- 30303462 TI - Implementation science and prevention in action: Application in a post-permanency world. AB - : This article describes how implementation science and intervention research guided the process of selecting and implementing an evidence-informed intervention (Tuning in to Teens; TINT). TINT was provided as a selective prevention effort offered to families with youth aged 10 to 13 years old, with characteristics that suggest an elevated risk for post-permanency discontinuity. Usability testing findings: Contact was made with 54% of families, and 12% participated in the intervention. Multivariate results found no statistically significant differences between families who responded to outreach efforts and those who did not; families who participated in TINT and those who did not. IMPLICATIONS: Large public child welfare systems wanting to implement evidence informed interventions can follow the steps detailed in this paper for selecting, adapting and implementing an intervention. Further, providers that seek to offer post adoption and guardianship services, a growing service need, may gain some insights into activities that promote service usage with this population. PMID- 30303464 TI - Postural control of Parkour athletes compared to recreationally active subjects under different sensory manipulations: A pilot study. AB - In Parkour activity, the aim is to move from one place to another as quickly and efficiently as possible by running, climbing, swinging, vaulting, rolling, crawling and jumping on tiny obstacles ... . Performing these actions places a great demand on the postural control system. The purpose of the present study was to investigate postural control of Parkour practitioners - called Traceurs - compared to recreationally active (RA) subjects in different postural conditions after manipulating the visual and/or proprioceptive sensory inputs. Ten Traceurs (mean experience 5.9 +/- 0.9 years; >5 hours per week) and 10 RA subjects participated in this study. We measured the centre of pressure area (CoPA) of the upright standing bipedal and unipedal postures in different postural conditions: on a firm and on a foam surfaces; on an oscillating surface in the sagittal plane and in the frontal plane in eyes open and eyes closed. To evaluate vision contribution, the Romberg index (RI) was calculated. Results showed that Traceurs presented a significant (P < .001) lower CoPA values compared to RA subjects in eyes closed condition, suggesting that they were able to maintain a better balance control when vision is removed. Traceurs seems to be less dependent on visual cues (lower RI values) and proprioceptive inputs for maintaining balance than RA subjects. According to our study, Parkour training (experience for at least five years with a minimum of five hours per week) may improve postural abilities of young adult practitioners in specific postural conditions. PMID- 30303463 TI - Synthesis and characterization of albumin imprinted polymeric hydrogel membranes for proteomic studies. AB - In this presented study, a novel molecularly imprinted polymeric hydrogel membranes (PHMs) were developed to use for the albumin depletion studies. For this, albumin imprinted poly(2-hydroxyethyl methacrylate-N-methacryloyl-(L) phenylalanine methyl ester) polymeric hydrogel membranes [p(HEMA-MAP) PHMs] were synthesized by the photopolymerization technique, and then characterized by SEM, EDX, FT-IR and swelling studies. Synthesized PHMs had spherical structure and the MAP monomer incorporation onto the PHMs was determined by EDX analysis by using nitrogen stoichiometry. Also, the swelling ratio of the albumin imprinted p(HEMA MAP) PHMs was determined as 215%. The optimum albumin adsorption condition (adsorption capacity, medium pH, adsorption rate, temperature, ionic strength) were studied and the maximum albumin adsorption capacity was found to be as 34.28 mg/g PHMs. Selectivity experiments were also carried out with the presence of the competitive proteins such as lysozyme and amylase, and the results demonstrated that the albumin imprinted p(HEMA-MAP) PHMs showed high affinity towards the BSA molecules than the competitive proteins of lysozyme and amylase. Adsorbed albumin was desorbed from the PHMs by 1.0 M of NaCl, and the reusability of the imprinted PHMs was also demonstrated for five successive adsorption-desorption cycles without any significant loss in the albumin adsorption capacity. As an application, sodium-dodecyl sulfate polyacrylamide gel electrophoresis was used to indicate the albumin depletion efficiency of albumin imprinted p(HEMA-MAP) PHMs. This presented study showed that, these imprinted membranes are promising for proteomic studies and applications, and can be used for the investigations for human diagnostics. PMID- 30303466 TI - The Relationship Between Residential Mobility and Behavioral Health Service Use in a National Sample of Adults With Mental Health and/or Substance Abuse Problems. AB - OBJECTIVE: Individuals with mental health and/or substance abuse problems experience disparities in health care utilization. While previous studies have focused on individual and social determinants of health care use in these populations, few have investigated the role of residential stability, especially in relation to different types of service use (i.e., inpatient vs. outpatient treatment). The present study examined the relationship between residential mobility, defined as the number of residential relocations in the past year, and past-year use of four types of behavioral services (i.e., inpatient and outpatient mental health services, inpatient and outpatient substance abuse services) among a national sample of adults with mental health and/or substance abuse problems. METHODS: Data were drawn from the 2011-2014 National Survey of Drug Use and Health (unweighted N = 43,411). Based on prior literature and theory, we hypothesized that individuals who frequently relocate are more likely to use inpatient services and are less likely to use outpatient services. Logistic regression analyses were conducted and all models controlled for predisposing, need, and enabling factors. RESULTS: Compared to individuals who did not move in the past year, those who moved three or more times were more likely to report using inpatient mental health and substance abuse services. The relationship between residential mobility and outpatient mental health and substance use service use is not significant. CONCLUSIONS: The findings highlight the importance of understanding housing stability as a predictor factor of service use and access. Future research is needed to shed light on the pathway through which residential mobility affects behavioral health service utilization.

AB - Graphene oxide (GO) is a new promising nanometer material in a superconductor and wastewater heavy metal ions removal for its functionalized groups. Ethylenediaminetetraacetic acid functionalized graphene oxide complexes (EDTA-GO) was produced by a realizable silanization chemical reaction. Characteristics of Hg(II) removal in desulphurization wastewater was also under investigation. The chemical composition and microstructures of the EDTA-GO adsorbents were characterized by X-ray photoelectron spectroscopy (XPS), Transmission electron microscope (TEM), Scanning Electron Microscopy (SEM) analyses. To investigate the performance of EDTA-GO adsorbents on adsorption of Hg(II) in wastewater of wet flue gas desulphurization (WFGD), experiments were performed to optimize the main influence factors such as reaction temperatures (35-70 degrees C), pH values(2 13), contact time (0-120 min), initial Hg(II) concentrations(800 ug/L) and adsorbent doses (20-50 mg/L). The maximum uptake removal efficiency (97.14%) was achieved under the optimal conditions at the pH of 7, the temperature of 70 degrees C, the Hg(II) concentration of 1200 MUg/L and the EDTA-GO dose of 40 mg/L. The kinetic data fitting results were well consistent with the pseudo second-order model (R2 = 0.99997) and a spontaneous and endothermic adsorption reaction was elaborated by thermodynamics studies (DeltaG < 0, DeltaH > 0, DeltaS > 0). The experiments of recycled adsorbents by HCl generation were carried out to obtain the performance of the reused EDTA-GO adsorbent, the fourth regenerative adsorption efficiency still maintained 80.4%, which indicated that excellent potential application in desulphurization wastewater treatment.

PMID- 30303468 TI - Fusarium subtropicale, sp. nov., a novel nivalenol mycotoxin-producing species isolated from barley (Hordeum vulgare) in Brazil and sister to F. praegraminearum. AB - Surveys were conducted in commercial wheat and barley fields in the south central production regions of state of Parana, Brazil, from 2011 to 2015. Spikes displaying visible Fusarium head blight symptoms were collected and the pathogen isolated from the tissues. The 754 Fusarium isolates recovered were identified by a high-throughput multilocus genotyping assay (MLGT) designed to identify trichothecene toxin-producing fusaria (i.e., formerly B-clade, but referred to here as F. sambucinum species complex lineage 1 [FSAMSC-1]) together with sequencing a portion of the translation elongation factor 1-alpha (TEF1) gene. One strain was discovered that appeared to be closely related to but phylogenetically distinct from F. praegraminearum based on the relatively low 97.7% TEF1 identity and positive genotype obtained with one of the two F. praegraminearum species-specific MLGT probes. Molecular phylogenetic analyses of a 10-gene data set resolved this novel FSAMSC-1 species and F. praegraminearum as sisters. Formally described herein as F. subtropicale, it is phenotypically distinct from the 22 other FSAMSC-1 species in that it produces mostly 1-3 septate macroconidia. Whole-genome sequence data were used to predict its potential to produce mycotoxins. Chemical analyses confirmed that F. subtropicale could produce the mycotoxins 4,15-diacetylnivalenol, butenolide, culmorin, and fusarin C in vitro, and the pathogenicity experiment revealed that F. subtropicale could infect but not spread in susceptible hard red spring wheat cultivar "Norm." PMID- 30303470 TI - Screening for risk of low energy availability in athletic and recreationally active females in Ireland. AB - INTRODUCTION: Low energy availability (LEA) results in physiological adaptations, which can contribute to unfavourable health outcomes. Little information exists on risk of LEA in active individuals competing in different sports or levels of competition. The aims of this study were to (1) identify risk of LEA in females competing at different levels of competition and (2) investigate associations between risk of LEA, illness and dietary habits. METHODS: The validated questionnaire, 'Low Energy Availability in Females Questionnaire' was distributed online (November 2016-February 2017) to assess risk of LEA. Twenty-nine additional questions collected information on demographics, illness history and dietary habits. Participants were considered at risk of LEA if they attained a score of >= 8 and were grouped into: (i) international; (ii) provincial/inter county; (iii) competitive; and (iv) recreationally active. Chi-square and logistic regression analyses were used to explore differences between those at risk or not at risk of LEA. RESULTS: Risk of LEA was identified in 40% (n = 331) of 833 participants and was 1.7 and 1.8 times more likely in international and provincial/inter-county athletes compared to those who were recreationally active (International: odds ratios (OR) 1.68, 95% confidence intervals (95%CI) 1.12 2.54; Provincial/inter-county: OR 1.83, 95%CI 1.20-2.77). In participants at risk of LEA, missing >22 days of training during the previous year due to illness occurred 3 times more frequently (OR 3.01, 95%CI 1.81-5.02). CONCLUSION: Risk of LEA was widespread in this heterogeneous sample. Awareness of LEA and the development of appropriate energy management strategies to ensure athlete health across levels of competition are required. PMID- 30303469 TI - Improvement of recombinant-truncated Burkholderia motility protein A (BimA)-based indirect ELISA for equine glanders. AB - Glanders is a contagious and highly fatal disease of equines with zoonotic potential. It is caused by a Gram-negative, nonmotile bacterium Burkholderia mallei. Complement fixation test (CFT) is one of the most commonly used tests for diagnosis of glanders; however, it has some limitations. A recombinant-truncated Burkholderia intracellular motility A (BimA) protein-based indirect enzyme-linked immunosorbent assay (iELISA) was previously reported by us for glanders diagnosis, which has been re-optimized in this study using a panel of glanders positive (n = 75) and glanders negative (n = 227) serum samples. The improved iELISA exhibited 96% sensitivity and 90.75% specificity. The assay had 98.56% negative predictive value. In the improved iELISA, background for negative samples was reduced and a rational assay cut-off based on ROC curves was introduced. Intra laboratory repeatability of the iELISA was tested by 3 different operators with 100% correlation. The BimA-coated ELISA plates could be used without significant decrease in diagnostic efficacy even after their storage at room temperature or 37 degrees C for 90 days. Overall, the improved iELISA is a sensitive, specific, reproducible, and easy-to-use assay that has potential in serodiagnosis of glanders, more suitably to demonstrate freedom from B. mallei infection in a population. PMID- 30303471 TI - Industry use of 'better-for-you' features on labels of sugar-containing beverages. AB - OBJECTIVE: To examine the ways in which sugar-containing beverages are being portrayed as 'better-for-you' (BFY) via features on product labels. DESIGN: Cross sectional audit of beverage labels. SETTING: Adelaide, Australia. Data on beverage labels were collected from seventeen grocery stores during September to November 2016. SUBJECTS: The content of 945 sugar-containing beverages labels were analysed for explicit and implicit features positioning them as healthy or BFY. RESULTS: The mean sugar content of beverages was high at 8.3 g/100 ml and most sugar-containing beverages (87.7 %) displayed features that position them as BFY. This was most commonly achieved by indicating the beverages are natural (76.8 %), or contain reduced or natural energy/sugar content (48.4 %), or through suggesting that they contribute to meeting bodily needs for nutrition (28.9 %) or health (15.1 %). Features positioning beverages as BFY were more common among certain categories of beverages, namely coconut waters, iced teas, sports drinks and juices. CONCLUSIONS: A large proportion of sugar-containing beverages use features on labels that position them as healthy or BFY despite containing high amounts of sugar. PMID- 30303472 TI - Streptomyces durbertensis sp. nov., isolated from saline-alkali soil. AB - A novel strain of actinobacteria, designated NEAU-S1GS20T, was isolated from a saline-alkali soil collected from Heilongjiang Province, north-east China, and characterized using a polyphasic approach. Strain NEAU-S1GS20T exhibited morphological, cultural and chemotaxonomic features consistent with its classification as representing a member of the genus Streptomyces. Growth occurred at 18-45 degrees C, at pH 6.0-10.0 and in the presence of 10 % (w/v) NaCl. Whole-cell hydrolysates mainly contained glucose and ribose. The predominant menaquinones were MK-9(H4) and MK-9(H6). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and two unidentified phospholipids. The major cellular fatty acids (>10 %) were iso-C16 : 0, iso-C17 : 0, anteiso-C17 : 0 and C16 : 0. The G+C content of the DNA was 72.8 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain NEAU-S1GS20T formed a distinct clade within the genus Streptomyces and was closely related to Streptomyces xinghaiensis CCTCC AA 208049T (98.4 % similarity), Streptomyces chumphonensis JCM 18522T (98.1 %) and Streptomyces palmae JCM 31289T (98.1 %). Multilocus sequence analysis (MLSA) using five housekeeping genes (atpD, gyrB, recA, rpoB and trpB) showed that the MLSA distance of strain NEAU-S1GS20T to the most closely related species was greater than the 0.007 threshold. A combination of DNA-DNA hybridization results and differences in certain phenotypic characteristics demonstrated that strain NEAU S1GS20T could be distinguished from its closest phylogenetic relatives. Therefore, strain NEAU-S1GS20T represents a novel species of the genus Streptomyces, for which the name Streptomyces durbertensis sp. nov. is proposed. The type strain is NEAU-S1GS20T (=CCTCC AA 2017006T=DSM 104538T). PMID- 30303473 TI - Herbaspirillum piri sp. nov., isolated from bark of a pear tree. AB - A Gram-stain-negative, aerobic, motile bacterial strain, shQ-4T, was isolated from a pear tree in Henan Province, China. The strain grew at 10-41 degrees C, at pH 4.0-8.0 and in the presence of 1-3 % (w/v) NaCl. It shared highest 16S rRNA gene sequence similarity (96.66 %) with Herbaspirillum chlorophenolicum CPW301T. The phylogenetic tree based on 16S rRNA gene sequences showed that strain shQ-4T formed a distinct branch next to reference species in the genus Herbaspirillum. The profile of major polar lipids of strain shQ-4T contained phosphatidylethanolamine (PE), diphosphatidylglycerol (DPG), phosphatidylglycerol (PG) and an unidentified aminophospholipid (APL). The major respiratory quinone was Q-8. The major fatty acids of this strain were C16 : 0, summed feature 3 (C16 : 1omega6c/C16 : 1omega7c), C17 : 0 cyclo and C18 : 0. Strain shQ-4T is considered to represent a novel species of the genus Herbaspirillum, with the proposed name Herbaspirillum piri sp. nov. The type strain is shQ-4T (=CFCC 14641T=KCTC 52804T).

AB - Five bacterial strains, UAE-HKU57T, UAE-HKU58, UAE-HKU59, UAE-HKU60 and UAE HKU61, were isolated in Dubai, UAE, from necrotic foot tissue samples of four dromedaries (Camelus dromedarius) and associated maggots (Wohrlfartia species). They were non-sporulating, Gram-negative, non-motile bacilli. They grew well under aerobic conditions at 37 degrees C, but not anaerobically. The pH range for growth was pH 7.0-9.0 (optimum, pH 7.5-8.0) and the strains could tolerate NaCl concentrations (w/v) up to 2 % (optimum, 0.5 %). They were catalase- and cytochrome oxidase-positive, but caseinase-, gelatinase- and urease-negative. Their phenotypic characters were distinguishable from other closely related species. Phylogenetic analyses of the almost-complete 16S rRNA gene and partial 23S rRNA gene, gyrB, groEL and recA sequences revealed that the five isolates were most closely related to undescribed Ignatzschineria strain F8392 and Ignatzschineria indica, but in most phylogenies clustered separately from these close relatives. Average nucleotide identity analysis showed that genomes of the five isolates (2.47-2.52 Mb, G+C content 41.71-41.86 mol%) were 98.00-99.97% similar to each other, but <=87.18 % similar to other Ignatzschineriaspecies/strains. Low DNA relatedness between the five isolates to other Ignatzschineriaspecies/strains was also supported by Genome-to-Genome Distance Calculator analysis. The chemotaxonomic traits of the five strains were highly similar. They were non-susceptible (intermediate or resistant) to tetracycline and resistant to trimethoprim/sulphamethoxazole. The name Ignatzschineria cameli sp. nov. is proposed to accommodate these five strains, with strain UAE-HKU57T (=CCOS1165T=NBRC 113042T) as the type strain. PMID- 30303477 TI - Streptomyces lichenis sp. nov., isolated from lichen. AB - A new actinobacterial strain, LCR6-01T, was isolated from a lichen sample collected from Chiang Rai Province, Thailand. Its taxonomic position was determined using a polyphasic approach. The strain had morphological characteristics and chemotaxonomic properties identical to those of members of the genus Streptomyces. The predominant menaquinones were MK-9(H6) and MK-9(H8). The major fatty acids were anteiso-C15 : 0, iso-C15 : 0, iso-C16 : 0, iso-C14 : 0 and C16 : 0. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, an unidentified phosphoglycolipid, an unidentified phospholipid and an unidentified lipid. The genomic DNA G+C content was 74.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences suggested that the strain belonged to the genus Streptomyces. The strain showed highest 16S rRNA gene sequence similarity to Streptomyces palmae TBRC 1999T (98.6 %), Streptomyces misionensis JCM 4497T (98.6 %), Streptomyces matensis JCM 4268T (98.5 %), Streptomyces althioticus KCTC 9752T (98.5 %) and Streptomyces wuyuanensis KCTC 29112T (98.4 %). DNA-DNA relatedness values among the strain and closely related Streptomyces species were below 70 %. On the basis of the phenotypic characteristics and genotypic distinctiveness, strain LCR6-01T is considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces lichenis sp. nov. is proposed. The type strain is LCR6-01T (=KCTC 39908T=TISTR 2500T). PMID- 30303476 TI - Hanstruepera crassostreae sp. nov., a novel marine bacterium of the family Flavobacteriaceae isolated from an oyster. AB - A Gram-stain-negative, rod-shaped, non-motile, aerobic and orange-pigmented marine bacterium, designated strain L53T, was isolated from an oyster sample collected from the coast of Weihai, China (122.0 degrees E 37.5 degrees N). Growth of strain L53T occurred at 4-40 degrees C (optimum, 33 degrees C), at pH 6.5-8.0 (optimum, pH 7.5) and with 1.0-7.0 % (w/v) NaCl (optimum, 3.0 %). Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain L53T was closely related to Bizionia echini KCTC 22015T (96.9 %) and Hanstruepera neustonica JCM 19743T (96.1 %). Strain L53T was located in a distinct phyletic lineage in a discrete clade associated with H. neustonica JCM 19743T. The DNA G+C content of strain L53T was 33.5 mol%. The sole menaquinone was MK-6. The polar lipids comprised one phosphatidylethanolamine, four unidentified aminolipids and four unidentified lipids. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3 OH and iso-C15 : 0 G. Based on morphological, physiological and molecular properties as well as on phylogenetic distinctiveness, strain L53T should be placed in the genus Hanstruepera as representing a novel species, for which the name Hanstruepera crassostreae sp. nov. is proposed. The type strain is L53T (=KCTC 62247T=MCCC 1H00246T). PMID- 30303478 TI - Polymorphic variability in the exon 19 of the RB1 gene and its flanking intronic sequences in HPV16-associated precancerous lesions in the Greek population. AB - PURPOSE: The tumour suppressor protein RB plays a decisive role in negative control of the cell cycle, inhibiting tumour development. The present analysis investigated the prevalence of the nucleotide polymorphism A153104G, which is located at intron 18 of the RB1 gene, and investigated the impact of the polymorphic variability in the exon 19 and its flanking intronic sequences on the severity of cervical disease in HPV16-positive Greek women. METHODOLOGY: The nucleotide polymorphism A153104G was detected by PCR-RFLP assay, while the amplicons were further subjected to cloning and sequencing. Moreover, molecular evolutionary analysis was performed using the maximum-likelihood (ML) and empirical Bayesian (EB) methods in order to evaluate the selective pressure acting on exon 19 of the RB1 gene.Results/Key findings. The A153104G nucleotide polymorphism was only detected in one control case. Moreover, sequence analysis of the amplicons revealed that the polymorphic variability in the RB1 gene increased with the severity of the cervical dysplasia. The link between the observed polymorphic variability and the progress of cervical disease was reflected in the molecular evolutionary analysis that was performed on the exon 19 of the RB1 gene, since negative selective pressure was acting upon exon 19 in the control and low-grade squamous intraepithelial lesion (LSIL) cervical samples, while positive selective pressure was acting upon exon 19 in the high grade squamous intraepithelial lesion (HSIL) specimens. CONCLUSIONS: The A153104G nucleotide polymorphism did not emerge as a potential biomarker for the development of precancerous lesions in the Greek patients, while the accumulation of sequence variations in RB1 gene might influence patients' susceptibility towards the progression of cervical neoplasia. PMID- 30303480 TI - Australian porcine clonal complex 10 (CC10) Escherichia coli belong to multiple sublineages of a highly diverse global CC10 phylogeny. AB - We recently identified clonal complex 10 (CC10) Escherichia coli as the predominant clonal group in two populations of healthy Australian food-production pigs. CC10 are highly successful, colonizing humans, food-production animals, fresh produce and environmental niches. Furthermore, E. coli within CC10 are frequently drug resistant and increasingly reported as human and animal extra intestinal pathogens. In order to develop a high-resolution global phylogeny and determine the repertoire of antimicrobial-resistance genes, virulence-associated genes and plasmid types within this clonal group, we downloaded 228 publicly available CC10 short-read genome sequences for comparison with 20 porcine CC10 we have previously described. Core genome single nucleotide polymorphism phylogeny revealed a highly diverse global phylogeny consisting of multiple lineages that did not cluster by geography or source of the isolates. Australian porcine strains belonged to several of these divergent lineages, indicative that CC10 is present in these animals due to multiple colonization events. Differences in resistance gene and plasmid carriage between porcine strains and the global collection highlighted the role of lateral gene transfer in the evolution of CC10 strains. Virulence profiles typical of extra-intestinal pathogenic E. coli were present in both Australian porcine strains and the broader collection. As both the core phylogeny and accessory gene characteristics appeared unrelated to the geography or source of the isolates, it is likely that the global expansion of CC10 is not a recent event and may be associated with faecal carriage in humans. PMID- 30303479 TI - Within-host Mycobacterium tuberculosis diversity and its utility for inferences of transmission. AB - Whole genome sequencing in conjunction with traditional epidemiology has been used to reconstruct transmission networks of Mycobacterium tuberculosis during outbreaks. Given its low mutation rate, genetic diversity within M. tuberculosis outbreaks can be extremely limited - making it difficult to determine precisely who transmitted to whom. In addition to consensus SNPs (cSNPs), examining heterogeneous alleles (hSNPs) has been proposed to improve resolution. However, few studies have examined the potential biases in detecting these hSNPs. Here, we analysed genome sequence data from 25 specimens from British Columbia, Canada. Specimens were sequenced to a depth of 112-296*. We observed biases in read depth, base quality, strand distribution and read placement where possible hSNPs were initially identified, so we applied conservative filters to reduce false positives. Overall, there was phylogenetic concordance between the observed 2542 cSNP and 63 hSNP loci. Furthermore, we identified hSNPs shared exclusively by epidemiologically linked patients, supporting their use in transmission inferences. We conclude that hSNPs may add resolution to transmission networks, particularly where the overall genetic diversity is low. PMID- 30303481 TI - Development of a rapid colorimetric multiplex PCR-reverse line blot for the detection and typing of 14 Chlamydia trachomatis genovars. AB - PURPOSE: Chlamydia trachomatis is responsible for trachoma-associated blindness as well as the most common sexually transmitted bacterial infection worldwide, although the genovars for the former are typically A-C, whilst for the latter they are D-K and for the uncommon infection lymphogranuloma venereum they are L1 3. Nucleotide variations within the ompA gene facilitate the identification of C. trachomatis genovars. This study describes a colorimetric multiplex PCR/RLB typing assay (mPCR-RLB) directed to the VD2 region of the ompA gene for general C. trachomatis positivity and the identification of 14 individual C. trachomatis genovars. METHODOLOGY: The assay was validated by analysing 40 blinded samples that included reference strains of C. trachomatis genovars and other non chlamydial micro-organisms that had been analysed previously using quantitative PCR (qPCR). Ninety clinical samples that had previously been found to be C. trachomatis-positive by qPCR were also evaluated using the mPCR-RLB assay. RESULTS: The mPCR-RLB assay showed 100 % agreement with the qPCR in the detection of C. trachomatis reference strains and no cross-reaction of non-chlamydial micro organisms was observed. In the analysis of the chlamydial clinical samples, 97.8 % were C. trachomatis-positive by mPCR/RLB assay and there was a 96.6 % concordance with the qPCR at the group identification level and a 92.2 % concordance at the genovar level. CONCLUSION: The mPCR-RLB assay is a rapid and sensitive methodology for the identification of C. trachomatis genovars associated with urogenital infections, trachoma or lymphogranuloma venereum diseases that can be implemented in clinical settings, helping to identify reinfections and treatment failures and establish the appropriate treatment course.

PMID- 30303485 TI - Examination of diabetes management apps recommended from a Google search: Dr Google, which app should I use? AB - BACKGROUND: The availability of smartphone health apps empowers people to engage in self-care. There are currently over 300,000 health apps available on the market targeting a variety of user needs from weight loss to management of chronic conditions, with diabetes being the most commonly targeted condition. To date, health apps largely fall outside government regulation, and there are no official guidelines to help clinicians and patients in app selection. Patients commonly resort to the internet for suggestions on which diabetes app to use. OBJECTIVE: To investigate apps identified through a Google search and characterize these apps in terms of features which support diabetes management. METHODS: We performed a Google search for the "best diabetes apps 2017", and explored the first four search results. We identified and compiled a list of the apps recommended in the returned search results, which were web articles. Information about each app was extracted from the articles and corresponding app store descriptions. We examined the apps for the following diabetes management features: medication management, blood glucose self-management, physical activity, diet/nutrition and weight management. RESULTS: Twenty-six apps were recommended from four articles. One app was listed in all four articles, and three apps appeared on three of the four lists. Apart from one article, there were no explicit criteria to justify or explain the selection of apps. We found wide variation in the type and the number of diabetes management features in the recommended apps. Five apps required payment in order to be used. Two-thirds of the apps have blood glucose management features, and less than half have medication management features. The most prevalent app features were nutrition/diet-related (79%) and physical activity tracking (58%). CONCLUSIONS: The ambiguity of app selection and the wide variability in key features of the apps recommended for diabetes management makes it difficult for patients to select the most appropriate app. It is critical to involve clinicians, relevant professional bodies and policymakers to define the key features an app should have for it to be classified as a "diabetes management" app. The lessons learned here should be taken into account when recommending and developing apps for other chronic conditions. PMID- 30303482 TI - Context-enriched interactome powered by proteomics helps the identification of novel regulators of macrophage activation. AB - The role of pro-inflammatory macrophage activation in cardiovascular disease (CVD) is a complex one amenable to network approaches. While an indispensible tool for elucidating the molecular underpinnings of complex diseases including CVD, the interactome is limited in its utility as it is not specific to any cell type, experimental condition or disease state. We introduced context-specificity to the interactome by combining it with co-abundance networks derived from unbiased proteomics measurements from activated macrophage-like cells. Each macrophage phenotype contributed to certain regions of the interactome. Using a network proximity-based prioritization method on the combined network, we predicted potential regulators of macrophage activation. Prediction performance significantly increased with the addition of co-abundance edges, and the prioritized candidates captured inflammation, immunity and CVD signatures. Integrating the novel network topology with transcriptomics and proteomics revealed top candidate drivers of inflammation. In vitro loss-of-function experiments demonstrated the regulatory role of these proteins in pro inflammatory signaling.

PMID- 30303486 TI - The Relationship Between Acceptance Intention Toward a Smartphone Healthcare Application and Health-Promoting Behaviors Among Nursing Students. AB - The purpose of this study was to identify the relationship between acceptance intention toward a smartphone healthcare application and health-promoting behaviors among nursing students in order to propose a method to encourage nursing students' personal health management. Data were collected from June to July 2015 in two cities located in South Korea, targeting 450 nursing students. There was a weak positive relationship between acceptance intention toward a smartphone healthcare application and health-promoting behaviors (r = 0.281, P < .001). There were differences in health-promoting behaviors according to the level of acceptance intention toward a smartphone healthcare application: health promoting behavior scores for the upper 50% of participants with higher intention scores (high-score group) were statistically higher than those for the lower 50% of participants (low-score group) (t = 4.247, P < .001). In the logistic regression, the high-score group had a greater likelihood of performing health promoting behaviors (odds ratio, 2.260; P < .001, 95% confidence interval, 1.539 3.321). Health-promoting behaviors tended to increase among nursing students when the acceptance intention toward a smartphone healthcare application was high. To increase nursing students' intention to accept a smartphone healthcare application, it is necessary to develop applications featuring diverse, interesting health-related content suitable for their needs, so that they want to use these applications to promote health. PMID- 30303484 TI - Ongoing, rational calibration of reward-driven perceptual biases. AB - Decision-making is often interpreted in terms of normative computations that maximize a particular reward function for stable, average behaviors. Aberrations from the reward-maximizing solutions, either across subjects or across different sessions for the same subject, are often interpreted as reflecting poor learning or physical limitations. Here we show that such aberrations may instead reflect the involvement of additional satisficing and heuristic principles. For an asymmetric-reward perceptual decision-making task, three monkeys produced adaptive biases in response to changes in reward asymmetries and perceptual sensitivity. Their choices and response times were consistent with a normative accumulate-to-bound process. However, their context-dependent adjustments to this process deviated slightly but systematically from the reward-maximizing solutions. These adjustments were instead consistent with a rational process to find satisficing solutions based on the gradient of each monkey's reward-rate function. These results suggest new dimensions for assessing the rational and idiosyncratic aspects of flexible decision-making. PMID- 30303489 TI - Plasma YKL-40 levels correlate with the severity of coronary atherosclerosis assessed with the SYNTAX score. AB - Introduction YKL-40 is a protein released locally by inflammatory cells. Thus, it may constitute a biomarker of inflammatory conditions, such as atherosclerosis. Objectives The aim of the study was to determine YKL-40 levels in patients with ischemic heart disease and to analyze the correlation of this biomarker with the severity of coronary atherosclerosis. Patients and methods The study included 158 patients: 52 with stable ischemic heart disease and 67 with acute coronary syndrome: ST-segment elevation myocardial infarction (STEMI; n = 47) or non-ST segment elevation myocardial infarction (NSTEMI; n = 20). The control group included 39 individuals without abnormalities in coronary vessels. We evaluated plasma YKL-40 levels and their correlation with the severity of coronary atherosclerosis assessed with the SYNTAX score. Results Patients with myocardial infarction had higher plasma YKL-40 levels than those with stable ischemic disease (median [range], 235.3 [161.6-366.1] ng/ml vs 61.2 [53.1-83.1] ng/ml; P <0.001) or controls (median [range], 235.3 [161.6-366.1] ng/ml vs 55.7 [51.2 75.2] ng/ml; P <0.001). No differences were found in YKL-40 concentrations between STEMI and NSTEMI patients (median [range], 263 [150.3-363.7] ng/ml and 214.9 [163.4-367.6] ng/ml, respectively; P = 0.7). The SYNTAX score in patients with ischemic heart disease correlated positively with YKL-40 concentrations (R = 0.34; P <0.001). Conclusions YKL-40 can be considered a potential biomarker of coronary atherosclerosis severity. PMID- 30303490 TI - Symptoms of chronic bronchitis in individuals without chronic obstructive pulmonary disease: prevalence, burden, and risk factors in southern Poland. AB - Introduction Chronic bronchitis (CB) symptoms are commonly reported in individuals without chronic obstructive pulmonary disease (COPD), but CB is rarely diagnosed in this population. Objectives We aimed to determine the prevalence and burden of CB, as well as its risk factors, in a population of patients without COPD. Patients and methods Data from the "Health Action" program (a lung cancer prevention and health care improvement program conducted in Proszowice County, Poland) were used. All county inhabitants aged 40 years or older without COPD were invited to participate. As part of the program, a questionnaire was administered to assess CB symptoms and risk factors. Spirometry at baseline and after the bronchodilator test was also performed. Results CB symptoms were present in 9.1% of the 3558 participants. The prevalence of CB in the study population was 7.12% (95% CI, 6.70-7.56). Patients with CB had more dyspnea and more often received medical treatment for lung disease or were hospitalized for respiratory disorders than patients without CB. CB was associated with worse lung function and a worse score in the modified Medical Research Council Dyspnea Scale even after adjustment for possible confounders. In a multivariate analysis, male sex, age over 70 years, current smoking, passive exposure to tobacco smoke, gas or wood heating, occupational exposure to chemical agents, lower forced expiratory volume in 1 second, and asthma correlated with an increased risk of CB. Conclusions CB symptoms are common in individuals without COPD aged 40 years or older and are associated with more dyspnea irrespective of lung function and comorbidities. PMID- 30303488 TI - Development of a novel aortic dissection mouse model and evaluation of drug efficacy using in-vivo assays and database analyses. AB - OBJECTIVE: Aortic dissection is a life-threatening disease. At present, the only therapeutic strategies available are surgery and antihypertensive drugs. Moreover, the molecular mechanisms underlying the onset of aortic dissection are still unclear. We established a novel aortic dissection model in mice using pharmacologically induced endothelial dysfunction. We then used the Japanese Adverse Drug Event Report database to investigate the role of pitavastatin in preventing the onset of aortic dissection. METHODS AND RESULTS: To induce endothelial dysfunction, Nomega-nitro-L-arginine methyl ester, a nitric oxide synthase inhibitor, was administered to C57BL/6 mice. Three weeks later, angiotensin II (Ang II) and beta-aminopropionitrile (BAPN), a lysyl oxidase inhibitor, were administered with osmotic mini-pumps. False lumen formation was used as the pathological determinant of aortic dissection. The incidences of aortic dissection and death from aneurysmal rupture were significantly higher in the Nomega-nitro-L-arginine methyl ester, Ang II, and BAPN (LAB) group than they were in the Ang II and BAPN (AB) group.Pitavastatin was administered orally to LAB mice. It significantly lowered the incidences of dissection and rupture. It also decreased inflammation and medial degradation, both of which were exacerbated in the LAB group. The Japanese Adverse Drug Event Report database analysis indicated that there were 113 cases of aortic dissection out of 95 090 patients (0.12%) not receiving statins but only six cases out of 16 668 patients receiving statins (0.04%) (odds ratio: 0.30; P = 0.0043). CONCLUSION: Our results suggest that endothelial dysfunction is associated with the onset of aortic dissection and pitavastatin can help prevent this condition. PMID- 30303491 TI - Effect of beta-blockers on 1-year survival and hospitalizations in patients with heart failure and atrial fibrillation: results from ESC-HF Pilot and ESC-HF Long Term Registry. AB - Introduction The positive effect of beta-blocker therapy in patients with heart failure (HF) and atrial fibrillation (AF) has been questioned. Objectives We aimed to assess the effect of beta-blockers and heart rate (HR) control on 1-year outcomes in patients with HF and AF. Patients and methods Of the 2019 Polish patients enrolled in ESC-HF Pilot and ESC-HF Long-Term Registry, 797 patients with HF and AF were classified into 2 groups depending on beta-blocker use. Additionally, patient survival was compared between 3 groups classified according to HR: lower than 80 bpm, between 80 and 109 bpm, and of 110 bpm or higher. The primary endpoint was all-cause death and the secondary endpoint was all-cause death or HF hospitalization. Results In patients treated with beta-blockers, the primary and secondary endpoints were less frequent than in patients not using beta-blockers (10.9% vs 25.6%, P = 0.001 and 30.6% vs 44.2%, P = 0.02, respectively). Absence of beta-blocker treatment was a predictor of both endpoints in a univariate analysis but remained an independent predictor only of the primary endpoint in a multivariate analysis (hazard ratio for beta-blocker use, 0.52; 95% CI, 0.31-0.89; P = 0.02). The primary and secondary endpoints were more frequent in patients with a HR of 110 bpm or higher, but the HR itself did not predict the study endpoints in the univariate analysis. Conclusions beta blocker use might decrease mortality in patients with HF and AF, but it seems to have no impact on the risk of HF hospitalization. An HR of 110 bpm or higher may be related to worse survival in these patients. PMID- 30303492 TI - Plazomicin for the treatment of patients with complicated urinary tract infection. AB - In June 2018, the United States Food and Drug Administration (FDA) approved plazomicin, a novel neoglycoside, for the treatment of adults with complicated urinary tract infections who have limited or no alternative treatment options. This approval was based on substantial preclinical and clinical work, and marks an important advance in the treatment of multidrug-resistant bacterial pathogens. This manuscript reviews the in vivo and in vitro work that led to the approval of plazomicin and examines how the drug may be used in the years ahead to treat patients with aggressive and life-threatening infections. PMID- 30303493 TI - An update on tolvaptan for autosomal dominant polycystic kidney disease. AB - Tolvaptan is an orally active antagonist of vasopressin (antidiuretic hormone [ADH]) V2 receptors. By blocking water reabsorption in kidney collecting ducts, it prompts renal free-water excretion and has been used for the treatment of hyponatremia, both euvolemic due to the syndrome of inappropriate ADH secretion, and hypervolemic due to liver cirrhosis and congestive heart failure. In the past few years, it has been shown that vasopressin and its second messenger cyclic adenosine monophosphate (cAMP) play an important role in the pathogenesis of autosomal dominant polycystic kidney disease (ADPKD). This has been the rationale for the use of tolvaptan to halt the progression of ADPKD, mainly through slowing kidney growth and decline in renal function. Two major randomized clinical trials have demonstrated the benefits of tolvaptan in slowing the progression of ADPKD in terms of kidney growth and decline in renal function at 1 and 3 years (REPRISE and TEMPO). However, the long-term effectiveness of treatment with tolvaptan remains to be determined. PMID- 30303494 TI - Update on multikinase inhibitor therapy for differentiated thyroid cancer. AB - Curative therapies for radioiodine-refractory differentiated thyroid cancer remain lacking. However, oral multikinase inhibitors often allow for disease control and improved progression-free survival. Two agents, lenvatinib and sorafenib, have been approved for radioiodine-refractory differentiated thyroid cancer on the basis of phase III clinical trials showing marked response rates and improved progression-free survival over placebo. Several other multikinase inhibitors, including apatinib, axitinib, cabozantinib, pazopanib, sunitinib and vandetanib, have also been studied in phase II clinical trials, with varying response rates and comparable progression-free survival. Selective kinase inhibitors, including dabrafenib, vemurafenib, selumetinib and gefitinib, offer a more targeted approach and have also been studied in phase II clinical trials. While the emergence of these treatments has changed the landscape of management of advanced thyroid cancer, clinical challenges remain, and there are many areas of ongoing research. PMID- 30303495 TI - Cardiovascular effects of antidiabetic drugs. AB - Type 2 diabetes mellitus is a common and severe chronic metabolic disease, which confers increased risk of cardiovascular disease and mortality. During the last decade a large number of new drugs within the classes dipeptidyl peptidase 4 (DPP 4) inhibitors (DPP-4Is), glucagon-like peptide 1 (GLP-1) receptor agonists (GLP 1RAs) and sodium/glucose cotransporter 2 (SGLT-2) inhibitors (SGLT-2Is) have been developed and tested in nine large-scale cardiovascular outcome trials (CVOTs). Here we review the evidence behind antihyperglycemic treatment of patients with type 2 diabetes with a particular focus on compiling and summarizing the evidence of hard clinical endpoints stemming from these large CVOTs. PMID- 30303496 TI - Renal complications of cancer therapies. AB - Cancer patients often exhibit preexisting renal impairment and are simultaneously at risk for developing further kidney injury due to direct or indirect complications of oncological therapies. The nature of kidney injury is highly dependent on the therapy regimen used, and the spectrum of possible kidney stressors has widened as a result of the development of new therapeutic modalities such as molecular therapy or immunotherapy. Indirect renal complications are often due to volume depletion or other therapy-related side effects. Direct toxicity from "classic" chemotherapy treatments such as cisplatin usually leads to acute tubular necrosis, whereas treatment with protein kinase inhibitors is more likely to cause disorders such as thrombotic microangiopathy. Immunotherapy often affects kidneys through the development of acute interstitial nephritis. Because of the high risk of nephrological complications in oncological patients, close monitoring of renal function and the early involvement of a nephrologist are strongly recommended. PMID- 30303497 TI - On the influence of the titanium source on the composition and structure of novel titanoniobates. AB - Systematic variation of the titanium source and the reaction temperature applied during hydrothermal synthesis led to crystallization of four new titanoniobates: {[Ni(cyclam)]4[Ti2Nb8O28]}n.~28nH2O (I), K[Ni(cyclam)]3[TiNb9O28].xH2O; x = 18 (II), x = 14 (III) and x ~ 10 (IV). These are the first titanoniobates with Ni2+ centered amine complexes acting as counter cations and additionally, this is the first report of transition metal complexes expanded by monotitanoniobates. While I is obtained using Ti(OiPr)4, II-IV are formed using K2TiO(C2O4).2H2O as the educt. The presence of oxalate anions seems to influence the coordination environments of the Ni2+ cations that are octahedrally coordinated in I, and in a square-planar environment in II-IV. The titanium source also affects the degree of substitution of NbV by TiIV. Temperature-dependent syntheses demonstrate that the formation of I does not depend on the reaction temperature, while the formation of II-IV is clearly affected by this parameter. Regarding the arrangement of crystal water molecules, patterns of different dimensionalities ranging from 0D to 3D are formed which can be classified as water clusters. Each compound exhibits a pronounced plateau in the thermogravimetric curves after the removal of crystal H2O molecules. Rehydration experiments after water removal proved that except for compound III, the re-integration of water was successful. PMID- 30303498 TI - Synthesis, cytotoxic activity and DNA interaction studies of new dinuclear platinum(ii) complexes with an aromatic 1,5-naphthyridine bridging ligand: DNA binding mode of polynuclear platinum(ii) complexes in relation to the complex structure. AB - The synthesis, spectroscopic characterization, cytotoxic activity and DNA binding evaluation of seven new dinuclear platinum(ii) complexes Pt1-Pt7, with the general formula [{Pt(L)Cl}2(MU-1,5-nphe)](ClO4)2 (1,5-nphe is 1,5-naphthyridine; while L is two ammines (Pt1) or one bidentate coordinated diamine: ethylenediamine (Pt2), (+/-)-1,2-propylenediamine (Pt3), trans-(+/-)-1,2 diaminocyclohexane (Pt4), 1,3-propylenediamine (Pt5), 2,2-dimethyl-1,3 propylenediamine (Pt6), and 1,3-pentanediamine (Pt7)), were reported. In vitro cytotoxic activity of these complexes was evaluated against three tumor cell lines, murine colon carcinoma (CT26), murine mammary carcinoma (4T1) and murine lung cancer (LLC1) and two normal cell lines, murine mesenchymal stem cells (MSC) and human fibroblast (MRC-5) cells. The results of the MTT assay indicate that all investigated complexes have almost no cytotoxic effects on 4T1 and very low cytotoxicity toward LLC1 cell lines. In contrast to the effects on LLC1 and 4T1 cells, complexes Pt1 and Pt2 had significant cytotoxic activity toward CT26 cells. Complex Pt1 had a much lower IC50 value for activity on CT26 cells compared with cisplatin. In comparison with cisplatin, all dinuclear Pt1-Pt7 complexes showed lower cytotoxicity toward normal MSC and MRC-5 cells. In order to measure the amount of platinum(ii) complexes taken up by the cells, we quantified the cellular platinum content using inductively coupled plasma mass spectrometry (ICP-QMS). Molecular docking studies performed to evaluate the potential binding mode of dinuclear platinum(ii) complexes Pt1-Pt7 and their aqua derivatives W1-W7, respectively, at the double stranded DNA showed that groove spanning and backbone tracking are the most stable binding modes.

AB - Optical diffraction tomography (ODT) enables the reconstruction of the three dimensional (3D) refractive-index (RI) distribution of a biological cell, which provides invaluable information for cellular and subcellular structures in a non invasive manner. However, ODT suffers from an inferior axial resolution, due to the limited accessible angles imposed by the numerical aperture of the objective lens. In this study, we propose and experimentally demonstrate an approach to enhance the 3D reconstruction performance in ODT. By employing trapezoidal micromirrors, side scattered signals from the sample are measured for various side plane-wave-illumination angles. By combining the side scattered fields with the forward scattered fields, the axial resolution and 3D image quality of ODT are improved, without changing optical instruments. The feasibility and applicability of the proposed method are demonstrated by reconstructing the 3D RI distribution of a red blood cell and HeLa cells in hydrogel. We also present systematic analyses of the improved 3D imaging performance using numerical simulations and experimental measurements for the 3D transfer function, a point object, and a microsphere. The analyses demonstrate an improved axial resolution of 0.31 MUm, 4.8 times smaller than that of the conventional method. The proposed method enables the non-invasive and accurate 3D imaging of 3D cultured cells, which is crucial for cell biology studies.

AB - Targeted delivery of nanomaterials to specific intracellular locations is essential for the development of many nanomaterials-based biological applications. Thus far the targeting performance has been limited due to various intracellular transport barriers, especially intracellular vesicle trapping. Here we report the application of permeation enhancers based on organic solvents in small percentage to enhance the intracellular targeted delivery of nanomaterials. Previously permeation enhancers based on organic solvents and ionic liquids have been used in overcoming biological transport barriers at tissue, organ, and cellular levels, but this strategy has so far rarely been examined for its potential in facilitating transport of nanometer-scale entities across intracellular barriers, particularly intracellular vesicle trapping. Using the cell nucleus as a model intracellular target and Tat peptide-conjugated quantum dots (QDs-Tat) as a model nanomaterial-based probe, we demonstrate that a small percentage (e.g. 1%) of organic solvent greatly enhances nucleus targeting specificity as well as increasing endocytosis-based cellular uptake of QDs. We combine vesicle colocalization (DiO dye staining), vesicle integrity (calcein dye release), and single-particle studies (pair-correlation function microscopy) to investigate the process of organic solvent-enhanced vesicle escape of QDs-Tat. The organic solvent based vesicle escape-enhancing approach is found to be not only very effective but minimally invasive, resulting in high vesicle escape efficiency with no significant disruption to the membrane integrity of either intracellular vesicles or cells. This approach drastically outperforms the commonly used vesicle escape-enhancing agent (i.e., chloroquine, whose enhancement effect is based on disrupting vesicle integrity) in both potency and minimal invasiveness. Finally, we apply organic solvent-based targeting enhancement to improve the intracellular delivery of the anticancer drug doxorubicin (DOX). PMID- 30303502 TI - Monitoring individual cell-signaling activity using combined metal-clad waveguide and surface-enhanced fluorescence imaging. AB - Evanescent field based biosensing systems such as surface plasmon resonance (SPR), diffraction gratings, or metal-clad waveguides (MCWGs) are powerful tools for label-free real-time monitoring of signaling activity of living cells exposed to hormones, pharmacological agents, and toxins. In particular, MCWG-based imaging is well suited for studying relatively thick objects such as cells due to its greater depth of penetration into the sensing medium, compared to SPR. Label free methods, however, provide only indirect measurements in that the measured signal arises from local changes in material properties rather than from specific biomolecular targets. In the case of cells, the situation is especially complex as the measured label-free signal may result from a combination of very diverse sources: morphological changes, intra-cellular reorganization, cascaded molecular events, protein expression etc. Consequently, deconvolving the contributions of specific sources to a particular cell response profile can be challenging. In the following, we present a cell imaging platform that combines two distinct sensing modalities, namely label-free MCWG imaging and label-based surface enhanced fluorescence (SEF), designed to facilitate the identification of the underlying molecular and structural contributions to the label-free MCWG images. We demonstrate the bimodal capabilities of this imaging platform in experiments designed to visualize actin cytoskeleton organization in vascular smooth muscle cells. We then monitored the real-time response of HEK293 cells expressing the Angiotensin 1 receptor (AT1R), when stimulated by the receptor agonist Angiotensin II (AngII). The analysis of the simultaneous label-free signal obtained by MCWG and the intracellular calcium signal resulting form AT1R activation, measured by SEF, allows relating label-free signal features to specific markers of receptor activation. Our results show that the intracellular calcium levels normally observed following AT1R activation are not required for the initial burst of cellular activity observed in the MCWG signal but rather indicates signaling activity involving the intracellular kinase ROCK. PMID- 30303501 TI - Quantification of hyperpolarisation efficiency in SABRE and SABRE-Relay enhanced NMR spectroscopy. AB - para-Hydrogen (p-H2) induced polarisation (PHIP) is an increasingly popular method for sensitivity enhancement in NMR spectroscopy. Its growing popularity is due in part to the introduction of the signal amplification by reversible exchange (SABRE) method that generates renewable hyperpolarisation in target analytes in seconds. A key benefit of PHIP and SABRE is that p-H2 can be relatively easily and cheaply produced, with costs increasing with the desired level of p-H2 purity. In this work, the efficiency of the SABRE polarisation transfer is explored by measuring the level of analyte hyperpolarisation as a function of the level of p-H2 enrichment. A linear relationship was found between p-H2 enrichment and analyte 1H hyperpolarisation for a range of molecules, polarisation transfer catalysts, NMR detection fields and for both the SABRE and SABRE-Relay transfer mechanisms over the range 29-99% p-H2 purity. The gradient of these linear relationships were related to a simple theoretical model to define an overall efficiency parameter, E, that quantifies the net fraction of the available p-H2 polarisation that is transferred to the target analyte. We find that the efficiency of SABRE is independent of the NMR detection field and exceeds E = 20% for methyl-4,6-d2-nicotinate when using a previously optimised catalyst system. For the SABRE-Relay transfer mechanism, efficiencies of up to E = 1% were found for 1H polarisation of 1-propanol, when ammonia was used as the polarisation carrier. PMID- 30303503 TI - Chemically driven surface effects in polar intermetallic topological insulators A3Bi. AB - Surface electronic spectra, surface and bulk properties as well as the underlying chemical bonding characteristics in topological insulators with complex bonding patterns are considered for the example of cubic, polar intermetallics KNa2Bi, K3Bi and Rb3Bi (with the general formula A3Bi, A - alkali metal). Chemical bonding in A3Bi has a delocalized, polar character as elucidated by the Bader charge analysis in bulk and at the surface, by real-space bonding indicators and by the maximally localized-Wannier-function technique. We underpin emergent surface features in the electronic spectra that are driven by chemical bonding. The organization of these trivial and topological surface states is juxtaposed with the trends in the Bader charges at the surface and surface contributions to the on-site matrix elements of the ab initio Hamiltonian in the localized basis. The surface states are essentially affected by a large positive or negative on site contribution induced near the vacuum boundary, where the sign of the contribution depends on the surface termination. Based on our findings, the experimentally observed surface features in the related Na3Bi compound can be correctly interpreted. The listed aspects distinguish the title compounds from the HgX (X - chalcogen) series with the same fingerprint bulk-band dispersion near the Fermi level and similar symmetries, but with covalent bonding character. Surface effects investigated for A3Bi also can be expected for a wide range of compounds of various topological classes with a similar bonding type, and will define their surface reactivity. PMID- 30303504 TI - Fiber nanogratings induced by femtosecond pulse laser direct writing for in-line polarizer. AB - Self-organized fiber nanogratings (FNGs) induced by femtosecond pulse laser direct writing are demonstrated in optical silica fibers for the first time. Ge doping in the silica fiber core plays an important role in the formation of nanogratings. Negative changes in refractive index with sawtooth fluctuation and strong birefringence of FNGs were investigated by an optical fiber refractive index analyzer and a crossed polarization microscope, respectively. The polarization features of FNGs were characterized by the Mueller matrix analytical method and in-line polarizers based on FNGs were fabricated. FNGs are promising integrated components because of their prominent properties of polarization and salient compatibility with most fiber-optic systems. PMID- 30303505 TI - Zinc finger domains as therapeutic targets for metal-based compounds - an update. AB - Zinc finger proteins are one of the most abundant families of proteins and present a wide range of structures and functions. The structural zinc ion provides the correct conformation to specifically recognize DNA, RNA and protein sequences. Zinc fingers have essential functions in transcription, protein degradation, DNA repair, cell migration, and others. Recently, reports on the extensive participation of zinc fingers in disease have been published. On the other hand, much information remains to be unravelled as many genomes and proteomes are being reported. A variety of zinc fingers have been identified; however, their functions are still under investigation. Because zinc fingers have identified functions in several diseases, they are being increasingly recognized as drug targets. The replacement of Zn(ii) by another metal ion in zinc fingers is one of the most prominent methods of inhibition. From one side, zinc fingers play roles in the toxicity mechanisms of Ni(ii), Hg(ii), Cd(ii) and others. From the other side, gold, platinum, cobalt, and selenium complexes are amongst the compounds being developed as zinc finger inhibitors for therapy. The main challenge in the design of therapeutic zinc finger inhibitors is to achieve selectivity. Recently, the design of novel compounds and elucidation of the mechanisms of zinc substitution have renewed the possibilities of selective zinc finger inhibition by metal complexes. This review aims to update the status of novel strategies to selectively target zinc finger domains by metal complexes. PMID- 30303508 TI - Facile fabrication of direct solid-state Z-scheme g-C3N4/Fe2O3 heterojunction: a cost-effective photocatalyst with high efficiency for the degradation of aqueous organic pollutants. AB - Graphitic carbon nitride (g-C3N4) is a low cost photocatalyst for the visible light-driven degradation of aqueous organic pollutants. Nevertheless, the fast recombination of electron-hole pairs significantly inhibits its photocatalytic activity. Consequently, we report a novel strategy in which the low cost alpha Fe2O3 photocatalyst is in situ introduced to accelerate the photogenerated charge separation of g-C3N4 based on a Z-scheme mechanism. Under the irradiation of visible light, the photocatalytic activity significantly improved on coupling g C3N4 and alpha-Fe2O3, and a peak Rhodamine B (RhB) degradation efficiency of over 99% were observed. This value is significantly higher than that over pure g-C3N4 (ca. 67%) and alpha-Fe2O3 (ca. 6%). Additionally, the as-prepared g-C3N4/Fe2O3 exhibits highly stable photocatalytic activity. The loading of alpha-Fe2O3 on the g-C3N4 surface results in the formation of a direct solid-state Z-scheme structure. The improved separation of electron-hole pairs and strong redox ability of the charge carriers are responsible for the improved photocatalytic activity of g-C3N4/Fe2O3. Finally, the h+ and O2- radicals are confirmed as the major oxidation species and a possible photocatalytic mechanism is proposed in the g-C3N4/Fe2O3 reaction system. This work is of significance to promote the large-scale application of g-C3N4-based photocatalysts in water purification. PMID- 30303509 TI - Organic sulfur fingerprint indicates continued injection fluid signature 10 months after hydraulic fracturing. AB - Hydraulic fracturing requires the injection of large volumes of fluid to extract oil and gas from low permeability unconventional resources (e.g., shale, coalbed methane), resulting in the production of large volumes of highly complex and variable waste fluids. Shale gas fluid samples were collected from two hydraulically fractured wells in Morgantown, WV, USA at the Marcellus Shale Energy and Environment Laboratory (MSEEL) and analyzed using ultrahigh resolution mass spectrometry to investigate the dissolved organic sulfur (DOS) pool. Using a non-targeted approach, ions assigned DOS formulas were analyzed to identify dominant DOS classes, describe their temporal trends and their implications, and describe the molecular characteristics of the larger DOS pool. The average molecular weight of organic sulfur compounds in flowback decreased and was lowest in produced waters. The dominant DOS classes were putatively assigned to alcohol sulfate and alcohol ethoxysulfate surfactants, likely injected as fracturing fluid additives, on the basis of exact mass and homolog distribution matching. This DOS signature was identifiable 10 months after the initial injection of hydraulic fracturing fluid, and an absence of genes that code for alcohol ethoxysulfate degrading proteins (e.g., sulfatases) in the shale well genomes and metagenomes support that these additives are not readily degraded biologically and may continue to act as a chemical signature of the injected fluid. Understanding the diversity, lability, and fate of organic sulfur compounds in shale wells is important for engineering productive wells and preventing gas souring as well as understanding the consequences of unintended fluid release to the environment. The diversity of DOS, particularly more polar compounds, needs further investigation to determine if the identified characteristics and temporal patterns are unique to the analyzed wells or represent broader patterns found in other formations and under other operating conditions. PMID- 30303512 TI - A three-dimensional model to study human synovial pathology. AB - Therapeutic agents that are used by patients with rheumatic and musculoskeletal diseases were originally developed and tested in animal models, and although retrospective studies show a limited predictive value, it could be explained by the fact that there are no good in vitro alternatives. In this study, we developed a 3-dimensional synovial membrane model made of either human primary synovial cell suspensions or a mix of primary fibroblast-like synoviocytes and CD14+ mononuclear cells. We analyzed the composition of the mature micromasses by immunohistochemical staining and flow cytometry and show that the outer surface forms a lining layer consisting out of fibroblast-like and macrophage-like cells, reflecting the in vivo naive synovial membrane. To recreate the affected synovial membrane in rheumatoid arthritis (RA), the micromasses were exposed to the pro inflammatory cytokine Tumor Necrosis Factor Alpha (TNF-alpha). This led to increased pro-inflammatory cytokine expression and production and to hyperplasia of the membrane. To recreate the synovial membrane in osteoarthritis (OA), the micromasses were exposed to Transforming Growth Factor Beta (TGF-beta). This led to fibrosis-like changes of the membrane, including increased Alpha Smooth Muscle Actin and increased expression of fibrosis-related genes PLOD2 and COL1A1. Interestingly, the macrophages in the micromass showed phenotypic plasticity as prolonged TNF-alpha or TGF-beta stimulation strongly reduced the occurrence of Cluster of Differentiation 163-positive M2-like macrophages. We showed the plasticity of the micromasses as a synovial model for studying RA and OA pathology and propose that the synovial lining micromass system can be a good alternative for testing drugs. PMID- 30303513 TI - Botulinum toxin testing on animals is still a Europe-wide issue. AB - There have been significant developments in the use of animals to test Botulinum toxin products in Europe in recent years. This paper summarises and discusses these from the perspective of the animal protection organisation. A cell-based assay has been validated by Allergan and is now being used for the replacement of the mouse bioassay for the batch testing of their Botulinum toxin A products. Two further companies (Merz and Ipsen) have recently validated similar cell-based assays to replace animals in their batch testing. However, the number of animals being used in batch tests across Europe remains at record levels; an estimated 400,000 animals per year, based on official statistics and non-technical summaries. There are concerns from animal protection organisations about the authorisation of animal testing for Botulinum toxin products that are to be used for aesthetic purposes. Furthermore, should testing for companies that have not yet implemented the alternative method continue to be permitted under the EU Directive 2010/63 on the use of animals for scientific purposes? Whilst we are on the cusp of an era where the mouse bioassay has been replaced for the potency testing of Botulinum toxin A for injection, it is important that Europe sees a reduction of animal testing in real terms. PMID- 30303514 TI - Short half-life of HPV16 E6 and E7 mRNAs sensitizes HPV16-positive tonsillar cancer cell line HN26 to DNA-damaging drugs. AB - Here we show that treatment of the HPV16-positive tonsillar cancer cell line HN26 with DNA alkylating cancer drug melphalan-induced p53 and activated apoptosis. Melphalan reduced the levels of RNA polymerase II and cellular transcription factor Sp1 that were associated with HPV16 DNA. The resulting inhibition of transcription caused a rapid loss of the HPV16 early mRNAs encoding E6 and E7 as a result of their inherent instability. As a consequence of HPV16 E6 and E7 down regulation, the DNA damage inflicted on the cells by melphalan caused induction of p53 and activation of apoptosis in the HN26 cells. The BARD1-negative phenotype of the HN26 cells may have contributed to the failure to repair DNA damage caused by melphalan, as well as to the efficient apoptosis induction. Finally, nude mice carrying the HPV16 positive tonsillar cancer cells responded better to melphalan than to cisplatin, the chemotherapeutic drug of choice for tonsillar cancer. We concluded that the short half-life of the HPV16 E6 and E7 mRNAs renders HPV16-driven tonsillar cancer cells particularly sensitive to DNA damaging agents such as melphalan since melphalan both inhibits transcription and causes DNA damage. PMID- 30303515 TI - Association between the dietary inflammatory index and all-cause mortality in colorectal cancer long-term survivors. AB - Pro-inflammatory dietary factors have been shown to be associated with the incidence of a range of cancers. However, there are many fewer studies on the association between the inflammatory potential of diet and survival after cancer diagnosis. We examined the association between post-diagnosis dietary inflammatory index (DII(r)) scores and all-cause mortality in long-term survivors of colorectal cancer (CRC). DII scores were calculated from dietary data of 1,404 CRC survivors collected at a median of 6 years after CRC diagnosis. Using multivariable-adjusted Cox proportional hazards regression models, hazard ratios (HR) and 95% confidence intervals (CI) were estimated for the association of DII scores, modeled continuous and in quartiles, with all-cause mortality. After a median follow-up time of 7 years (after dietary assessment), 204 study participants had died. Overall, in the fully adjusted model there was a suggestion of a positive association between DII score and all-cause mortality (HRDIIquartile4vs1 : 1.36; 95% CI: 0.88-2.09 and HRDIIcontinuous : 1.08; 95% CI: 0.97-1.20). However, in subgroup analyses, we found significant differences in individuals with metastatic disease (HRDIIcontinuous : 1.34; 95% CI: 1.07-1.67) and the absence of stoma (HRDIIcontinuous : 1.15; 95% CI: 1.02-1.29). Overall, the post-diagnosis DII was not statistically significantly associated with all cause mortality in CRC long-term survivors; however, there was suggestive evidence of an association in select subgroups. PMID- 30303516 TI - NCI 8628: A randomized phase 2 study of ziv-aflibercept and high-dose interleukin 2 or high-dose interleukin 2 alone for inoperable stage III or IV melanoma. AB - BACKGROUND: Interleukin 2 (IL-2) is a growth factor for T and natural killer cells, promotes proinflammatory cytokines, and can lead to durable responses in patients with melanoma. Vascular endothelial growth factor (VEGF) promotes angiogenesis and modulates host innate and adaptive immunity. High VEGF levels were found to be associated with nonresponse to IL-2. Ziv-aflibercept may deplete VEGF and thereby enhance antitumor T-cell responses, thus supporting a combination immunotherapeutic strategy with IL-2. METHODS: NCI 8628 was a phase 2 trial of ziv-aflibercept and IL-2 (arm A) versus IL-2 alone (arm B) randomized at 2:1, respectively. Eligible patients had inoperable American Joint Committee on Cancer stage III or stage IV melanoma. The primary endpoint was progression-free survival (PFS). RESULTS: A total of 89 patients were enrolled and 84 patients were treated. The median follow-up was 41.4 months. Among treated patients (55 patients in arm A and 29 patients in arm B), PFS was significantly improved in favor of arm A, with a median of 6.9 months (95% confidence interval [95% CI], 4.1-8.7 months) versus 2.3 months (95% CI, 1.6-3.5 months) (P<.001). No significant difference was noted with regard to overall survival, with a median of 26.9 months (95% CI, 14.4-63.6 months) for arm A and 24.2 months (95% CI, 11.3 36.4 months) for arm B. The response rate (according to Response Evaluation Criteria In Solid Tumors [RECIST]) was 22% in arm A (4 complete responses [CRs] and 8 partial responses [PRs]) and 17% in arm B (1 CR and 4 PRs). Stable disease or PR or CR was noted in 65% of patients in arm A and 48% of patients in arm B. The combination was found to be superior to monotherapy in patients with high and low levels of serum VEGF and VEGF receptor 2. Adverse events were consistent with the expected profiles of monotherapy with IL-2 and ziv-aflibercept. CONCLUSIONS: Ziv-aflibercept and IL-2 were found to significantly improve PFS compared with IL 2 alone, thereby meeting the primary endpoint of the current study. These findings support further study of immunotherapeutic combination strategies involving VEGF inhibitors. PMID- 30303517 TI - Association of breast cancer risk with polymorphisms in genes involved in the metabolism of xenobiotics and interaction with tobacco smoking: a gene-set analysis. AB - Single nucleotide polymorphisms (SNPs) in genes involved in xenobiotics metabolism (XM) are suspected to play a role in breast cancer risk. However, previous findings based on a SNP by SNP approach need to be replicated taking into account the combined effects of multiple SNPs. We used a gene-set analysis method to study the association between breast cancer risk and genetic variation in XM genes (seen as a set of SNPs) and in the XM pathway (seen as a set of genes). We also studied the interaction between variants in XM genes and tobacco smoking. The analysis was conducted in a case-control study of 1125 cases and 1172 controls. Using a dedicated chip, genotyping data of 585 SNPs in 68 XM genes were available. Genetic variation in the whole XM pathway was significantly associated with pre-menopausal breast cancer risk (p=0.008). This association was mainly driven by genetic variation in NAT2, CYP2C18, CYP2C19, AKR1C2 and ALDH1A3. The association between the XM gene pathway and breast cancer was observed among current and previous smokers, but not among never smokers (p=0.013 for interaction between XM genes and tobacco smoking status). The association with breast cancer risk indicates that XM genes variants may play a role in breast carcinogenesis through their detoxification function of environmental pollutants, such as those contained in tobacco smoke.

AB - In the United States, it is estimated that more than 1.7 million people will be diagnosed with cancer, and more than 600,000 will die of the disease in 2018. The financial costs associated with cancer risk factors and cancer care are enormous. To substantially reduce both the number of individuals diagnosed with and dying from cancer and the costs associated with cancer each year in the United States, government and industry and the public health, medical, and scientific communities must work together to develop, invest in, and implement comprehensive cancer control goals and strategies at the national level and expand ongoing initiatives at the state and local levels. This report is the second in a series of articles in this journal that, together, describe trends in cancer rates and the scientific evidence on cancer prevention, early detection, treatment, and survivorship to inform the identification of priorities for a comprehensive cancer control plan. Herein, we focus on existing evidence about established, modifiable risk factors for cancer, including prevalence estimates and the cancer burden due to each risk factor in the United States, and established primary prevention recommendations and interventions to reduce exposure to each risk factor. PMID- 30303519 TI - Eszopiclone for insomnia. AB - BACKGROUND: Insomnia is a major public health issue affecting between 6% to 10% of the adult population in Western countries. Eszopiclone is a hypnotic drug belonging to a newer group of hypnotic agents, known as new generation hypnotics, which was marketed as being just as effective as benzodiazepines for this condition, while being safer and having a lower risk for abuse and dependence. It is the aim of the review to integrate evidence from randomised controlled trials and to draw conclusions on eszopiclone's efficacy and safety profile, while taking methodological features and bias risks into consideration. OBJECTIVES: To assess the efficacy and safety of eszopiclone for the treatment of insomnia compared to placebo or active control. SEARCH METHODS: We searched the Cochrane Central Register of Controlled trials (CENTRAL), MEDLINE, Embase, PsycINFO, PSYNDEX and registry databases (WHO trials portal, ClinicalTrials.gov) with results incorporated from searches to 10 February 2016. To identify trials not registered in electronic databases, we contacted key informants and searched reference lists of identified studies. We ran an update search (21 February 2018) and have placed studies of interest in awaiting classification/ongoing studies. These will be incorporated into the next version of the review, as appropriate. SELECTION CRITERIA: Parallel group randomised controlled trials (RCTs) comparing eszopiclone with either placebo or active control were included in the review. Participants were adults with insomnia, as diagnosed with a standardised diagnostic system, including primary insomnia and comorbid insomnia. DATA COLLECTION AND ANALYSIS: Two authors independently extracted outcome data; one reviewer assessed trial quality and the second author cross-checked it. MAIN RESULTS: A total of 14 RCTs, with 4732 participants, were included in this review covering short-term (<= 4 weeks; 6 studies), medium-term (> 4 weeks <= 6 months; 6 studies) and long-term treatment (> 6 months; 2 studies) with eszopiclone. Most RCTs included in the review included participants aged between 18 and 64 years, three RCTs only included elderly participants (64 to 85 years) and one RCT included participants with a broader age range (35 to 85 years). Seven studies considered primary insomnia; the remaining studies considered secondary insomnia comorbid with depression (2), generalised anxiety (1), back pain (1), Parkinson's disease (1), rheumatoid arthritis (1) and menopausal transition (1).Meta-analytic integrations of participant-reported data on sleep efficacy outcomes demonstrated better results for eszopiclone compared to placebo: a 12-minute decrease of sleep onset latency (mean difference (MD) -11.94 min, 95% confidence interval (CI) 16.03 to -7.86; 9 studies, 2890 participants, moderate quality evidence), a 17 minute decrease of wake time after sleep onset (MD -17.02 min, 95% CI -24.89 to 9.15; 8 studies, 2295 participants, moderate quality evidence) and a 28-minute increase of total sleep time (MD 27.70 min, 95% CI 20.30 to 35.09; 10 studies, 2965 participants, moderate quality evidence). There were no significant changes from baseline to the first three nights after drug discontinuation for sleep onset latency (MD 17.00 min, 95% CI -4.29 to 38.29; 1 study, 291 participants, low quality evidence) and wake time after sleep onset (MD -6.71 min, 95% CI 21.25 to 7.83; 1 study, 291 participants, low quality evidence). Adverse events during treatment that were documented more frequently under eszopiclone compared to placebo included unpleasant taste (risk difference (RD) 0.18, 95% CI 0.14 to 0.21; 9 studies, 3787 participants), dry mouth (RD 0.04, 95% CI 0.02 to 0.06; 6 studies, 2802 participants), somnolence (RD 0.04, 95% CI 0.02 to 0.06; 8 studies, 3532 participants) and dizziness (RD 0.03, 95% CI 0.01 to 0.05; 7 studies, 2933 participants). According to the GRADE criteria, evidence was rated as being of moderate quality for sleep efficacy outcomes and adverse events and of low quality for rebound effects and next-day functioning. AUTHORS' CONCLUSIONS: Eszopiclone appears to be an efficient drug with moderate effects on sleep onset and maintenance. There was no or little evidence of harm if taken as recommended. However, as certain patient subgroups were underrepresented in RCTs included in the review, findings might not have displayed the entire spectrum of possible adverse events. Further, increased caution is required in elderly individuals with cognitive and motor impairments and individuals who are at increased risk of using eszopiclone in a non-recommended way. PMID- 30303521 TI - To delay or not to delay, that is the question for patients with acute lymphoblastic leukemia who do not receive prophylactic cranial irradiation. PMID- 30303522 TI - Congestive heart failure in older adults diagnosed with follicular lymphoma: A population-based study. AB - BACKGROUND: To the authors' knowledge, there is limited information regarding the long-term risk of congestive heart failure (CHF) among patients with follicular lymphoma, a prevalent non-Hodgkin lymphoma diagnosis among those aged >65 years, especially within the context of therapeutic exposures and preexisting comorbidities. METHODS: Using Surveillance, Epidemiology, and End Results Medicare data from 1999 through 2013, the authors identified 6109 patients with follicular lymphoma who were diagnosed at age >=66 years between January 1, 2000 and December 31, 2011, and a frequency-matched Medicare noncancer sample. Subdistribution hazards models assessed risks associated with new-onset CHF through December 31, 2013. Propensity score-matched models examined CHF risk in patients receiving anthracyclines when compared with matched noncancer controls. RESULTS: When compared with matched controls, patients with follicular lymphoma receiving anthracyclines at ages 66 to 75 years had a 1.7-fold (95% confidence interval, 1.4-fold to 2.1-fold) higher risk of new-onset CHF; patients diagnosed at age >75 years did not differ from noncancer controls with regard to CHF risk. Preexisting hypertension was associated with a 1.7-fold and 1.35-fold, respectively, increased hazard of CHF for each age group, independent of anthracycline exposure. Preexisting diabetes was associated with 1.5-fold increased hazard of CHF only in those patients aged 66 to 75 years. Patients with new-onset CHF had a 18% lower 10-year survival compared with those without CHF. CONCLUSIONS: Patients with follicular lymphoma who were exposed to anthracyclines between the ages of 66 years and 75 years were found to be at an increased risk of new-onset CHF; preexisting hypertension and diabetes appeared to increase this risk. The findings of the current study support and inform the risk-based follow up of vulnerable populations. PMID- 30303520 TI - Treatment of childhood acute lymphoblastic leukemia with delayed first intrathecal therapy and omission of prophylactic cranial irradiation: Results of the TPOG-ALL-2002 study. AB - BACKGROUND: To eliminate cranial irradiation (CrRT)-related sequelae and to minimize the adverse impact of traumatic lumbar puncture (TLP) with blasts, the Taiwan Pediatric Oncology Group (TPOG) introduced a modified central nervous system (CNS)-directed regimen characterized by delayed triple intrathecal therapy (TIT) and the omission of CrRT for all children with newly diagnosed acute lymphoblastic leukemia (ALL). METHODS: This study compared the treatment outcomes of patients overall and patients with a non-CNS-1 status (CNS-2, CNS-3, or TLP with blasts) in 2 treatment eras, one before and another after the revision of the TPOG-ALL-2002 protocol by the introduction of the modification (era 1 [2002 2008] with CrRT and era 2 [2009-2012] with delayed first TIT and no CrRT). RESULTS: There were no statistically significant differences in major outcomes between the 903 patients treated in era 1 and the 444 patients treated in era 2: the 5-year event-free survival (EFS) rates were 75.7% +/- 1.4% and 72.1% +/- 2.4%, respectively (P = .260), and the cumulative risks of isolated CNS relapse were 4.0% +/- 0.7% and 4.1% +/- 1.0%, respectively (P = .960). There were also no differences between non-CNS-1 patients treated in era 1 (n = 76) and era 2 (n =28): the 5-year EFS rates were 52.3% +/- 5.8% and 62.9% +/- 9.4%, respectively (P = .199), and the cumulative risks of isolated CNS relapse were 6.3% +/- 3.1% and 3.6% +/- 3.5%, respectively (P = .639). Notably, TLP with blasts was completely eliminated after the first TIT was delayed in era 2. CONCLUSIONS: The delay of the first TIT until the clearance of circulating blasts and the total omission of CrRT did not compromise survival or CNS control in patients with childhood ALL, including those with a non-CNS-1 status. PMID- 30303523 TI - A Rapid Method to Estimate Hepatocyte Loss Due to Drug-Induced Liver Injury. AB - It is not currently possible to rapidly estimate the extent of hepatocyte loss during drug-induced liver injury (DILI). We used a proprietary mechanistic model (DILIsym) to estimate percentage hepatocyte loss due to DILI that resulted from four different patterns of serum alanine aminotransferase (ALT) over time: rapid onset and rapid decrease in ALT levels, moderate onset and moderate decrease in ALT levels, moderate onset and extended duration (over 1 month) of ALT elevations, and an ALT profile with multiple peaks. Using these data, we derived a novel parameter, PALT = ALT_AUC*Peak ALT0.18 /105 ((IU/L)2 *h), where AUC is area under the curve, that correlated well with hepatocyte loss estimates derived by DILIsym in patients with DILI due to six different hepatotoxic drugs. Although further validation will be required, the fact that PALT can be derived rapidly using publicly available pharmacokinetic software may make it a useful parameter to improve the safety of drugs. PMID- 30303524 TI - Effects of temporal variation in community-level fruit abundance on seed dispersal by birds across woody species. AB - PREMISE OF THE STUDY: In animal-dispersed plants, seed dispersal patterns of the same species in the same habitat can greatly differ among individuals and temporally. Many studies have revealed the pervasive effects of spatial variation in fruit abundance on seed dispersal of individual plants. By contrast, very few studies have investigated the temporal variation in seed dispersal. METHODS: We investigated the effects of conspecific and community-level fruit abundance on fruit removal rate and seed dispersal distance of six bird-dispersed woody species in a Japanese temperate forest for 3 yr. The six species share similar fruit characteristics but have different fruiting seasons. In addition, we also considered the effects of bird seasonality in diet and species composition on seed dispersal. KEY RESULTS: Inter-annual and inter-seasonal variation in community-level fruit abundance determined both fruit removal and the seed dispersal distance across species, but the effect differed with seasonal changes in bird behavior. Abundant fruit satiated fruit removal by birds only during fruit-feeding periods, not during insect-feeding periods. A scarcity of fruit increased the dispersal distance, but only during the migratory period. This difference was probably due to the different foraging behaviors of passing migrants and territorial birds. CONCLUSIONS: Our results illustrated that temporal variation in community-level fruit abundance could be a determining factor for seed dispersal in temperate forests. The effects of temporal variations in fruit abundance on seed dispersal patterns should be investigated in other ecosystems in order to understand their importance and associations with frugivore phenology. PMID- 30303525 TI - BOS is associated with decreased HDAC2 from steroid resistant lymphocytes in the small airways. AB - Immunosuppression therapies including corticosteroids fail to prevent bronchiolitis obliterans syndrome (BOS), primarily a disease of the small airways, following lung transplantation. We reported increases in steroid resistant proinflammatory lymphocytes and their loss of histone deacetylase 2 (HDAC2), an important mediator of steroid action, in the blood of stable lung transplant recipients. We noted similar increases in the steroid-resistant lymphocytes in both the blood and small airways in BOS compared with the large airways. We hypothesized that these small airway cells would also exhibit a loss of HDAC2, and that these changes could be reversed by treatment with theophylline (HDAC2 activator). Blood, bronchoalveolar lavage and large and small airway brushings were collected from lung transplant patients with BOS (n = 12) or stable lung function (n = 18) and healthy aged-matched controls (n = 13). Intracellular proinflammatory cytokines [interferon (IFN-gamma) and tumour necrosis factor (TNF)-alpha and HDAC2 were measured in CD8+ T, natural killer (NK) T-like and NK cells from cultured small airway brushings +/- 5 mg/l theophylline +/- 1 uM prednisolone using flow cytometry. Increased small airway CD8 T, NK T-like and NK cells were identified in BOS versus stable transplant and controls. In BOS, these cells exhibited increased IFN-gamma/TNF-alpha and a loss of HDAC2. HDAC2 expression by small airway CD8+ T cells correlated with forced expiratory volume in 1 s (FEV1 ) (R = 0.880, P = 0.031). Theophylline and prednisolone synergistically up-regulated HDAC2 in CD8+ T cells. BOS is associated with loss of HDAC2 from steroid-resistant proinflammatory CD8+ T, NK T like and NK cells in the small airways. Therapeutically increasing HDAC2 in these lymphocytes may reduce steroid resistance and improve graft survival. PMID- 30303526 TI - Response to therapeutic monoclonal antibodies for multiple myeloma in African Americans versus whites. AB - BACKGROUND: Myeloma occurs disproportionately in African Americans, with disparities in outcomes potentially caused by access to care, cytogenetics, and immunity. A gap in knowledge of immune function dissimilarities between African Americans and whites exists. Data for other diseases suggest innate differences in immunity and inflammatory markers, with potential implications for therapeutic monoclonal antibodies reliant on secondary immune activation for activity. METHODS: Patients receiving daratumumab or elotuzumab, lenalidomide, and dexamethasone were retrospectively studied with a primary endpoint of response at 2 (daratumumab) or 4 months (elotuzumab). Secondary endpoints included stable disease or better at the same points, treatment duration, time to best response, and adverse events. RESULTS: Eighty patients were included; baseline characteristics were balanced with the exception of the stage at diagnosis, which was more advanced in African Americans. No statistically significant difference in response was seen: 37.9% in whites versus 11.8% in African Americans with daratumumab (P = .090) and 60% in whites versus 44% in African Americans with elotuzumab (P = .462). There were no differences in the duration of treatment, the time to best response, or adverse events. Common potential immune-related adverse events in both arms were fatigue (39%), back pain (30%), and infusion reactions (40%). Anemia was significantly associated with a response to daratumumab (P = .02); no patients without anemia responded at 2 months, whereas 34.4% of patients with anemia did. CONCLUSIONS: No significant difference in response, duration of treatment, or time to response was seen by race, although a trend toward greater early response rates in whites was observed. In these cohorts, as in other analyses, African American patients tended to present with later stage disease. PMID- 30303527 TI - The crab spider-pitcher plant relationship is a nutritional mutualism that is dependent on prey-resource quality. AB - Nutritional mutualisms are one of the three major categories of mutualisms and involve the provision of limiting nutrients (resources) to one species by another. It was recently shown in laboratory experiments that two species of pitcher-dwelling crab spiders (Thomisidae), Thomisus nepenthiphilus and Misumenops nepenthicola, increased capture rates of flesh flies (Sarcophagidae) for their host, Nepenthes gracilis. The spiders ambushed pitcher-visiting flesh flies and dropped their carcasses into pitchers after consuming them. The consumption of shared prey-resources by crab spiders and pitcher plants presents the possibility of parasitism between them. However, ecologically generalizable mechanisms that predict the context-dependent outcomes of such mutualisms are not known. The effectiveness framework (mutualism effectiveness = quality * quantity) is useful for examining the total effect of mutualisms, but its quality component can be difficult to define. We identify the crab spider-pitcher plant interaction as a type of resource conversion mutualism and propose that the quality component in such interactions is the amount of the underlying resource contained in each unit of resource processed. We then used the crab spider-pitcher plant interaction to test the hypothesis that resource conversion mutualisms are more beneficial to the nutrient recipient when operating through high-quality resources (i.e., large prey, in this interaction). We sampled the prey and inquilines of 107 N. gracilis upper pitches in situ and analysed the differences between pitchers that were inhabited or uninhabited by crab spiders, and the differences between nutritional contents of prey that were consumed by crab spiders or not. Pitchers inhabited by T. nepenthiphilus contained higher numbers of several prey taxa, many of which were flying insects. Consumption by T. nepenthiphilus reduced the nutrient contents in all prey examined. Overall, T. nepenthiphilus-assisted prey capture is likely to result in a net nutrient gain for N. gracilis that is proportional to the size of prey consumed by T. nepenthiphilus. Our results suggest that resource conversion mutualisms are more likely to operate through high-quality resources, since the nutrient-processing species necessarily reduces the quality of the resource it processes while increasing its availability to the nutrient recipient species. PMID- 30303528 TI - Innovation in Pharmacovigilance: Use of Artificial Intelligence in Adverse Event Case Processing. AB - Automation of pharmaceutical safety case processing represents a significant opportunity to impact the strongest cost driver for a company's overall pharmacovigilance budget. A pilot was undertaken to test the feasibility of employing artificial intelligence and robotic process automation to automate processing of adverse event reports. The pilot paradigm was used to simultaneously test proposed solutions of 3 commercial vendors. The result confirmed feasibility of using artificial intelligence-based technology to support extraction from adverse event source documents and evaluation of case validity. In addition, the pilot demonstrated viability of the use of safety database data fields as a surrogate for otherwise time-consuming and costly direct annotation of source documents. Finally, the evaluation and scoring method employed in the pilot was able to differentiate vendor capabilities, and identify the best candidate to move into the discovery phase.

PMID- 30303529 TI - The modular organization of the cerebral cortex: Evolutionary significance and possible links to neurodevelopmental conditions. AB - The recognition of discernible anatomical regularities that appear to self organize during development makes apparent the modular organization of the cerebral cortex. The metabolic cost engendered in sustaining interneuronal communications has emphasized the viability of short connections among neighboring neurons. This pattern of connectivity establishes a microcircuit which is repeated in parallel throughout the cerebral cortex. This canonical circuit is contained within the smallest module of information processing of the cerebral cortex; one which Vernon Mountcastle called the minicolumn. Plasticity within the brain is accounted, in part, by the presence of weak linkages that allow minicolumns to process information from a variety of sources and to quickly adapt to environmental exigencies without a need for genetic change. Recent research suggests that interlaminar correlated firing between minicolumns during the decision phase of target selection provides for the emergence of some executive functions. Bottlenecks of information processing within this modular minicolumnar organization may account for a variety of mental disorders observed in neurodevelopmental conditions. PMID- 30303530 TI - Intraspecific variation in lizard heat tolerance alters estimates of climate impact. AB - Research addressing the effects of global warming on the distribution and persistence of species generally assumes that population variation in thermal tolerance is spatially constant or overridden by interspecific variation. Typically, this rationale is implicit in sourcing one critical thermal maximum (CTmax ) population estimate per species to model spatiotemporal cross-taxa variation in heat tolerance. Theory suggests that such an approach could result in biased or imprecise estimates and forecasts of impact from climate warming, but limited empirical evidence in support of those expectations exists. We experimentally quantify the magnitude of intraspecific variation in CTmax among lizard populations, and the extent to which incorporating such variability can alter estimates of climate impact through a biophysical model. To do so, we measured CTmax from 59 populations of 15 Iberian lizard species (304 individuals). The overall median CTmax across all individuals from all species was 42.8 degrees C and ranged from 40.5 to 48.3 degrees C, with species medians decreasing through xeric, climate-generalist and mesic taxa. We found strong statistical support for intraspecific differentiation in CTmax by up to a median of 3 degrees C among populations. We show that annual restricted activity (operative temperature > CTmax ) over the Iberian distribution of our study species differs by a median of >80 hr per 25-km2 grid cell based on different population-level CTmax estimates. This discrepancy leads to predictions of spatial variation in annual restricted activity to change by more than 20 days for six of the study species. Considering that during restriction periods, reptiles should be unable to feed and reproduce, current projections of climate change impacts on the fitness of ectotherm fauna could be under- or over estimated depending on which population is chosen to represent the physiological spectra of the species in question. Mapping heat tolerance over the full geographical ranges of single species is thus critical to address cross-taxa patterns and drivers of heat tolerance in a biologically comprehensive way. PMID- 30303531 TI - Asymmetric competitive effects during species range expansion: An experimental assessment of interaction strength between "equivalent" grazer species in their range overlap. AB - Biotic interactions are central to the development of theory and concepts in community ecology; experimental evidence has shown their strong effects on patterns of population and community organization and dynamics over local spatial scales. The role of competition in determining range limits and preventing invasions at biogeographic scales is more controversial, partly because of the complexity of processes involved in species colonization of novel habitats and the difficulties in performing appropriate manipulations and controls. We examined experimentally whether competition is likely to affect poleward range expansion hindering or facilitating the establishment of the limpet Scurria viridula along the south-eastern Pacific rocky shore (30 degrees S, Chile) in the region occupied by the congeneric S. zebrina. We also assessed whether competition with the "invader" or range-expanding species could reduce individual performance of the "native" S. zebrina and depress local populations Geographic field surveys were conducted to characterize the abundance and identity of limpets along the south-eastern Pacific coast from 18 degrees S to 41 degrees S, and the micro-scale (few cm) spatial distribution across the range overlap of the two species. Field-based competition experiments were conducted at the southern leading edge of the range of S. viridula (33 degrees S) and at the northern limit of S. zebrina (30 degrees S). Field surveys showed poleward range expansion of S. viridula of ca. 210 km since year 2000, with an expansion rate of 13.1 km/year. No range shift was detected for S. zebrina. The resident S. zebrina had significant negative effects on the growth rate of the invading juvenile S. viridula, while no effect of the latter was found on S. zebrina. Spatial segregation between species was found at the scale of cms. Our results provide novel evidence of an asymmetric competitive effect of a resident species on an invader, which may hamper further range expansion. No negative effect of the invader on the resident species was detected. This study highlights the complexities of evaluating the role of species interactions in setting range limits of species, but showed how interspecific competition might slow the advance of an invader by reducing individual performance and overall population size at the advancing front. PMID- 30303532 TI - Prey-specific impact of cold pre-exposure on kill rate and reproduction. AB - Temperature influences biological processes of ectotherms including ecological interactions, but interaction strengths may depend on species-specific traits. Furthermore, ectotherms acclimate to prevailing thermal conditions by adjusting physiological parameters, which often implies costs to other fitness-related parameters. Both predators and prey may therefore pay thermal acclimation costs following exposure to suboptimal temperatures. However, these costs may be asymmetrical between predator and prey, and between the predator and different species of concurrent prey. We investigated whether thermal pre-exposure affected subsequent kill rate and predator fitness when foraging on prey that differ in ease of capture, and whether changes were primarily caused by predator or by prey pre-exposure effects. Specifically, we were interested in whether there were interactions between predator pre-exposed temperature and specific prey. Using the mesostigmatid mite Gaeolaelaps aculeifer as a generalist predator and the collembolans Folsomia candida and Protaphorura fimata as prey, we measured the impact of present temperature, predator pre-exposure temperature, prey pre exposure temperature (all 10 or 20 degrees C), prey species, and all interactions on prey numbers killed, predator eggs produced, and exploitation of killed prey in a full factorial design. Mites killed P. fimata in equal numbers independent of the presence of F. candida, but killed F. candida when P. fimata was absent. Mite kill rate and reproduction were significantly affected by mite pre-exposure temperature and test temperature, but not by prey pre-exposure temperature. Significantly more of the slower prey was killed than of the quicker prey. Importantly, we found significant synergistic negative interaction effects between predator cold pre-exposure and hunting prey of higher agility on predator kill rate and reproduction. Our findings show that the negative effects of cold and cold pre-exposure on kill rate and reproduction may be more severe when predators forage on quick prey. The study implies that predator cold exposure has consequences for specific prey survival following cold due to altered predation pressures, which in nature should influence the specific prey population dynamics and apparent competition outcomes. The findings exemplify how not only current but also preceding conditions affect ecological interactions, and that effect strength depends on the species involved. PMID- 30303533 TI - When can competition and dispersal lead to checkerboard distributions? AB - Checkerboard distributions-mutually exclusive species co-occurrences-are a common observation in community ecology and biogeography. While the underlying causes of checkerboard distributions have remained elusive, a long-standing argument is that they are representative of strong competitive interactions and/or dispersal limitation. We explore this using a stochastic two-patch metacommunity model combined with an experimental two-patch system of competing Tribolium species, quantifying checkerboard distributions using the abundance-based index Ast . We find that maintenance of checkerboard distributions is possible in a limited parameter space consisting of low dispersal rates, low population growth rates and high interspecific competition. Checkerboards were not maintained in experimental metacommunities. Our model, parameterized using independent data, echoed this finding, providing a clear link between model and experiment, and suggested that only small regions of parameter space would allow for checkerboard distributions between patches with equally hospitable environments. These findings may provide insight into when interspecific competition and dispersal limitation would promote checkerboard distributions. PMID- 30303534 TI - Toward the control of cancer. PMID- 30303535 TI - Decreased RORC expression and downstream signaling in HTLV-1-associated Adult T cell Lymphoma/Leukemia uncovers an antiproliferative IL17 link: a potential target for immunotherapy? AB - Retinoic acid-related drugs have shown promising pre-clinical activity in Adult T cell Leukemia/Lymphoma, but RORC signaling has not been explored. Therefore, we investigated transcriptome-wide interactions of the RORC pathway in HTLV-1 and ATL, using our own and publicly available gene expression data for ATL and other leukemias. Gene expression data from ATL patients were analyzed using WGCNA to determine gene modules and their correlation to clinical and molecular data. Both PBMCs and CD4+ T-cells showed decreased RORC expression in four different ATL cohorts. A small subset of RORChi ATL patients was identified with significantly lower pathognomonic CADM1 and HBZ levels but similar levels of other ATL markers (CD4/CD25/CCR4), hinting at a less aggressive ATL subtype. An age-dependent decrease in RORC expression was found in HTLV-1-infected individuals, but not in healthy controls, suggesting an early molecular event predisposing to leukemogenesis. Genes upstream of RORC signaling were members of a proliferative gene module (containing proliferation markers PCNA/Ki67), whereas downstream members clustered in an anti-proliferative gene module. IL17C transcripts showed the strongest negative correlation to PCNA in both ATL cohorts, which was replicated in two large cohorts of T- and B-cell acute lymphoid leukemia (ALL). Finally, IL17C expression in purified CD4+CCR4+CD26-CD7- 'ATL-like' cells from HTLV-1-infected individuals and ATL patients was negatively correlated with clonality, underscoring a possible antileukemic/antiproliferative role. In conclusion, decreased RORC expression and downstream signaling might represent an early event in ATL pathogenesis. An antiproliferative IL17C/PCNA link is shared between ATL, T-ALL and B-ALL, suggesting (immuno)therapeutic benefit of boosting RORC/IL17 signaling. This article is protected by copyright.

AB - OBJECTIVE: To evaluate the effectiveness of laser-assisted turbinectomy (LATE) in treating brachycephalic obstructive airway syndrome (BOAS) and to investigate the potential indications. STUDY DESIGN: Prospective clinical study. SAMPLE POPULATION: Client-owned pugs, French bulldogs, and English bulldogs (n = 57). METHODS: A BOAS index was obtained from whole-body barometric plethysmography before BOAS conventional multilevel surgery (CMS) and 2-6 months post-CMS. Dogs with BOAS index >50% and BOAS functional grades II-III after CMS were considered candidates for LATE. A BOAS index was repeated 2-6 months after LATE. Intranasal lesions and a measurement of soft tissue proportion at the rostral entrance of choanae (STC) were recorded on the basis of computed tomography images. Logistic regressions were used to assess the intranasal predictors for being LATE candidates. RESULTS: Twenty-nine of 57 dogs were candidates for LATE, all of which were pugs or French bulldogs. The median BOAS index of dogs that were operated on (20/29 candidates) decreased from 67% post-CMS to 42% after LATE (P < .001). Soft tissue proportion at the rostral entrance of choanae was the only predictor for candidacy for LATE. Pugs (P = .021; cutoff = 64%) and French bulldogs (P = .008; cutoff = 55%) with higher STC were more likely to be candidates for LATE. After LATE, 12 of 20 dogs had temporary episodes of reverse sneezing, and nasal noise was noted in 8 of 20 dogs when sniffing and excited. CONCLUSION: Laser-assisted turbinectomy was an effective treatment for dogs with intranasal abnormalities and a poor response to CMS. Soft tissue proportion at the rostral entrance of choanae was a predictor of candidacy for LATE in pugs and French bulldogs. CLINICAL SIGNIFICANCE: Computed tomography-based measurement of STC can be used to predict whether LATE is required in addition to CMS in pugs and French bulldogs with BOAS. PMID- 30303539 TI - Can subunit-specific phenotypes guide surveillance imaging decisions in asymptomatic SDH mutation carriers? AB - OBJECTIVE: With the discovery that familial phaeochromocytoma and paraganglioma syndrome can be caused by mutations in each subunit of the succinate dehydrogenase enzyme (SDH), has come the recognition that mutations in the individual subunits have their own distinct natural histories. Increased genetic screening is leading to the identification of increasing numbers of, mostly asymptomatic, gene mutation carriers and the implementation of screening strategies for these individuals. Yet there is, to date, no international consensus regarding screening strategies for asymptomatic carriers. DESIGN: A comprehensive PubMed search from 1/1/2000 to 28/2/2018 was undertaken using multiple search terms and subsequently a manual review of references in identified papers to identify all clinically relevant cases and cohorts. In this review, the accumulated, published experience of phenotype and malignancy risks of individual SDH subunits is analysed. Where possible screening results for asymptomatic SDH mutation carriers have been analysed separately to define the penetrance in asymptomatic carriers (asymptomatic penetrance). RESULTS: The combined data confirms that "asymptomatic penetrance" is highest for SDHD and when there is penetrance, the most likely site to develop a PGL is head and neck (SDHD) and extra-adrenal abdominal (SDHB). However, the risk in SDHB carriers of developing HNPGL is also high (35.5%) and a PCC is low (15.1%), and in SDHD carriers there is a high risk of developing a PCC (35.8%) or abdominal PGL (9.4%) and a small, but significant risk at other sympathetic sites. The data suggest that the risk of malignant transformation is the same for both PCC and extra adrenal abdominal PGLs (30%-35%) in SDHB carriers. In SDHD carriers, the risk of malignant transformation was highest in HNPGLs (7.5%) and similar for sympathetic sites (3.8%-5.2%). CONCLUSIONS: Using this data, we suggest surveillance screening of asymptomatic carriers can be tailored to the underlying SDH subunit and review possible surveillance programmes. PMID- 30303540 TI - Tibial plateau morphology in dogs with cranial cruciate ligament insufficiency. AB - OBJECTIVE: To identify possible biomechanical causes for the predominantly unilateral presentation of cranial cruciate ligament (CCL) insufficiency by comparing the computed tomographic (CT) features of the tibial plateau of CCL affected and contralateral sound stifles in dogs with unilateral CCL insufficiency. STUDY DESIGN: Cross-sectional study. ANIMALS: Eighteen dogs, 36 stifles. METHODS: Eighteen dogs with naturally occurring unilateral CCL insufficiency were included. Stifle CT and radiographs were performed at the time of diagnosis. Follow-up was performed at a minimum of 1 year from the original diagnosis to ensure that there was no evidence of contralateral CCL insufficiency. The medial tibial plateau angle (m-TPA), lateral TPA (and l-TPA), medial tibial plateau midsagittal radius of curvature (m-TPr), and lateral TPr (l TPr) were measured from the CT images. Variables were compared with paired t tests. A Bonferroni correction was performed, and P < .006 was considered significant. RESULTS: Mean m-TPr was steeper (P = .002) and m-TPr:l-TPr ratio was greater (P < .001) in affected stifles compared with contralateral sound stifles. No other variables differed between groups. Mean l-TPA was steeper than mean m TPA (P < .001). CONCLUSION: Tibial plateau convexity differed between the CCL affected and contralateral sound stifle in dogs with unilateral CCL insufficiency. CLINICAL SIGNIFICANCE: Medial tibial plateau convexity may play a role in the development of CCL insufficiency. PMID- 30303536 TI - From colorectal cancer pattern to the characterization of individuals at risk: Picture for genetic research in Latin America. AB - Colorectal cancer (CRC) is one of the most common cancers in Latin America and the Caribbean, with the highest rates reported for Uruguay, Brazil and Argentina. We provide a global snapshot of the CRC patterns, how screening is performed, and compared/contrasted to the genetic profile of Lynch syndrome (LS) in the region. From the literature, we find that only nine (20%) of the Latin America and the Caribbean countries have developed guidelines for early detection of CRC, and also with a low adherence. We describe a genetic profile of LS, including a total of 2,685 suspected families, where confirmed LS ranged from 8% in Uruguay and Argentina to 60% in Peru. Among confirmed LS, path_MLH1 variants were most commonly identified in Peru (82%), Mexico (80%), Chile (60%), and path_MSH2/EPCAM variants were most frequently identified in Colombia (80%) and Argentina (47%). Path_MSH6 and path_PMS2 variants were less common, but they showed important presence in Brazil (15%) and Chile (10%), respectively. Important differences exist at identifying LS families in Latin American countries, where the spectrum of path_MLH1 and path_MSH2 variants are those most frequently identified. Our findings have an impact on the evaluation of the patients and their relatives at risk for LS, derived from the gene affected. Although the awareness of hereditary cancer and genetic testing has improved in the last decade, it is remains deficient, with 39%-80% of the families not being identified for LS among those who actually met both the clinical criteria for LS and showed MMR deficiency. PMID- 30303541 TI - Relationship between renal CD68+ infiltrates and the oxford classification of iga nephropathy. AB - AIMS: The Oxford Classification E score (endocapillary hypercellularity) predicts renal functional decline in IgA nephropathy (IgAN) patients free from steroid/immunosuppressive (IS) therapy, but is poorly reproducible. We hypothesise that endocapillary hypercellularity reflects glomerular inflammation and that the presence of CD68-positive cells is a more robust marker of E score. METHODS AND RESULTS: CD68 positive cells were quantified in glomeruli and tubulointerstitium in biopsies from 118 IgAN patients, and cell counts were correlated with the criteria of the Oxford Classification, assigned on PAS stained serial sections. There was a strong correlation between median glomerular CD68 count and the percentage of glomeruli showing endocapillary hypercellularity (r=0.67; p<0.001; r2 =0.45) whilst there was no correlation between CD68-positive cells and mesangial hypercellularity, % segmental sclerosis, % of crescents and % tubular atrophy/interstitial fibrosis (TA/IF). ROC curve analysis demonstrated that a maximum glomerular CD68 count of 6 is the best cut-off for distinguishing E0 from E1 (sensitivity 94.1%, specificity 71%, area under the curve = 89%). Identification of biopsies with a maximum glomerular CD68-count >6 was reproducible (kappa score 0.8), and there was a strong correlation between glomerular CD68 counts obtained by conventional light microscopy and by image analysis (r=0.80, r2 =0.64, p=<0.0001). Digital image analysis revealed that tubulointerstitial CD68-positive cells correlated moderately with % TA/IF (r=0.59, r2 =0.35, p=<0.001) and GFR at the time of biopsy (r=0.54, r2 =0.29, p=<0.0001), but not with mesangial and endocapillary hypercellularity. CONCLUSIONS: Whilst glomerular CD68-positive cells emerge as markers of endocapillary hypercellularity, their tubulointerstitial counterparts are associated with chronic damage.

AB - This systematic review evaluates the safety and efficacy of intravenous (IV) lidocaine for the treatment of acute pain in adult patients. The PubMed database was searched for randomized controlled trials, retrospective cohort studies, case series, and case reports evaluating the use of IV lidocaine for the treatment of acute pain in adult patients, published between January 1970 and January 2018. The primary outcome was pain reduction via the Visual Analog Scale, Verbal Rating Scale, or Numeric Rating Scale among patients treated with IV lidocaine and placebo or active controls. Safety outcomes included both nonserious and serious adverse events. A total of 347 titles and abstracts were screened, and after full text review, 13 studies met the inclusion criteria involving 512 patients. The four active controls studied were IV morphine, IV ketorolac, IV dihydroergotamine (DHE), and IV chlorpromazine (CPZ). The dosing of IV lidocaine varied among studies between a weight-based dose of a 1- to 2-mg/kg bolus, a fixed-bolus dose of 50-100 mg, and a 1-mg/kg/hour continuous infusion. Monitoring of serum lidocaine concentrations was not done routinely. Intravenous lidocaine had superior efficacy to morphine for renal colic and critical limb ischemia, superior efficacy to DHE for acute migraine, and equivalent efficacy to ketorolac for acute radicular lower back pain. However, lidocaine was less effective than CPZ for the treatment of acute migraine. The most common adverse event reported among all studies were neurologic effects such as altered mental status and slurred speech. Due to the inconsistency in dosing, length of administration, and lack of serum monitoring, the absolute safety of IV lidocaine for acute pain is unknown. Larger, prospective studies are needed before the routine use of IV lidocaine can be recommended for all types of acute pain. PMID- 30303537 TI - Familial breast cancer and DNA repair genes: Insights into known and novel susceptibility genes from the GENESIS study, and implications for multigene panel testing. AB - Pathogenic variants in BRCA1 and BRCA2 only explain the underlying genetic cause of about 10% of hereditary breast and ovarian cancer families. Because of cost effectiveness, multigene panel testing is often performed even if the clinical utility of testing most of the genes remains questionable. The purpose of our study was to assess the contribution of rare, deleterious-predicted variants in DNA repair genes in familial breast cancer (BC) in a well-characterized and homogeneous population. We analyzed 113 DNA repair genes selected from either an exome sequencing or a candidate gene approach in the GENESIS study, which includes familial BC cases with no BRCA1 or BRCA2 mutation and having a sister with BC (N = 1,207), and general population controls (N = 1,199). Sequencing data were filtered for rare loss-of-function variants (LoF) and likely deleterious missense variants (MV). We confirmed associations between LoF and MV in PALB2, ATM and CHEK2 and BC occurrence. We also identified for the first time associations between FANCI, MAST1, POLH and RTEL1 and BC susceptibility. Unlike other associated genes, carriers of an ATM LoF had a significantly higher risk of developing BC than carriers of an ATM MV (ORLoF = 17.4 vs. ORMV = 1.6; p Het = 0.002). Hence, our approach allowed us to specify BC relative risks associated with deleterious-predicted variants in PALB2, ATM and CHEK2 and to add MAST1, POLH, RTEL1 and FANCI to the list of DNA repair genes possibly involved in BC susceptibility. We also highlight that different types of variants within the same gene can lead to different risk estimates.

AB - OBJECTIVE: To compare cutaneous wound closure with mesh and 2-octyl cyanoacrylate (MOC) vs an intradermal suture pattern (ISP) in terms of time of application and biomechanical properties. SAMPLE POPULATION: Experimental study with 12 female beagle dogs. METHODS: A skin incision was created from the xiphoid to the pubis as part of an ovariohysterectomy; the linea alba and subcutaneous tissue were closed routinely. Half of the skin incision was closed with MOC, and the other half was closed with an ISP. Tissue samples were collected from both sections at days 14 and 28 and tested for ultimate strength and stiffness. RESULTS: Closure with MOC (72.8 +/- 14.0 s) was faster than with an ISP (398.4 +/- 36.4 s; P = .001). The ultimate load and stiffness increased with time for MOC (P = .005 and P = .005, respectively) and ISP (P < .001 and P < .001, respectively). On day 14, ultimate load and stiffness were greater in wounds closed with MOC compared with ISP (P = .014 and P = .02, respectively). No difference between groups was detected at day 28. CONCLUSION: Cutaneous wound closure with MOC was faster and resulted in superior strength at 14 days compared with closure with an ISP in this healthy population. CLINICAL SIGNIFICANCE: Mesh and 2-octyl cyanoacrylate offers an attractive alternative to ISP for skin closure after celiotomy in dogs, especially if surgical/anesthesia time is a concern.

AB - The aim of this study was to assess the biodiversity of endophytic fungi from Arabidopsis arenosa growing on a post mining waste dump and to evaluate their role in plant adaptation to metal toxicity. Severeal of the fungi were beneficial for the plant. Among them, a fungus belonging to the Mucor genus, was found to interact with a broad range of plants, including Brassicaceae metallophytes. Mucor sp. was shown to be highly tolerant to elevated levels of Zn, Cd, and Pb and to accelerate plant-host growth under either toxic-metal stress or control conditions. When inoculated with Mucor sp., A. arenosa under toxic-metal stress acquired more N and showed significantly down-regulated catalase activity, which suggests suppression of toxic-metal-induced oxidative stress. We used the model plant-A. thaliana to evaluate the dynamics of plant-tissue colonization by the fungus as monitored with qPCR and to analyze the host's transcriptome response during early stages of the interaction. The results revealed the induction of a plant-defense and stress-related response on the 5th day of co-culture, which was in accord with the decrease of fungal abundance in shoots on the 6th day of interaction. Presented results demonstrate the importance of endophytic fungi in plant toxic-metal tolerance.

AB - OBJECTIVE: The sensory perception of cosmetic emulsions is complex as it is governed by an important number of parameters like the choice of raw materials, their interactions, the structural organisation of the system, etc. The aim of the present work was to go further in the interpretation of the emollient surfactant interactions, towards the emulsions applicative properties. For this purpose, two systems containing liquid crystals of the lamellar type were formulated, differing only in the selected emollient. METHODS: First, the liquid crystals types were checked using different tools like the optical microscopy under the bright and polarized light, the wide-angle X rays diffraction and, finally, thermogravimetric analysis. Next, two sensory attributes, namely compression force and difficulty of spreading, were evaluated by a sensory panel. In addition to that, complementary instrumental characterizations (flow tests, textural analysis and contact angle measurements) were performed in order to understand how the panel could discriminate the products. RESULTS: The results showed that isohexadecane emollient induces the alpha-gel structures, while caprylic capric triglycerides favour the formation of the lamellar liquid crystals near to alpha-gel. For the compression force, the results point out that there is no direct interaction between the oil phase and the skin. For this attribute, depending on its chemical structure, emollient impacts the human perception only by changing the lamellar phase type. Concerning the difficulty of spreading, both the emulsion structure and the emollient properties should be considered. Immediate perception is impacted by the emulsions destruction, making the droplet roll one on each other. Then, once the droplets monolayer is disrupted, the emollient comes into direct contact with the skin. In this case, the perception is governed by the direct affinity of the emollient with the skin, nonpolar emollients being easier to spread if compared to polar ones. CONCLUSION: The sensory perception is guided not only by the choice of the raw materials but also by their interactions. It was shown that the chemical structure of the emollients affected the molecular organization of liquid crystals present in the emulsion and, consequently, directly or indirectly its sensory perception. PMID- 30303547 TI - Community structure and fibrolytic activities of anaerobic rumen fungi in dromedary camels. AB - Anaerobic fungi colonize the rumen and degrade cellulose and hemicellulose, which enable them to be key players in the lignocellulose fermentation. Consequently, an expansion of knowledge about rumen fungi could increase animal productivity, utilization of lignified forages like alfalfa hay, and enhance fibrolytic enzymes production. Here, we used an Internal Transcribed Spacer 1 (ITS1) clone library to investigate the anaerobic rumen fungi in camel and to investigate their ability to produce cellulase and xylanase in vitro. Rumen fluid was collected from camels fed Egyptian clover (n = 14), and wheat straw (n = 7) and fecal samples were collected from camels fed wheat straw and concentrates (n = 5), or natural grazing plants (n = 10). Neocallimastix and Cyllamyces were the most abundant anaerobic fungi in all camel groups. An anaerobic rumen fungi media containing alfalfa hay as a carbon source was inoculated by rumen and fecal samples to assess the ability of anaerobic rumen fungi in camel gut to produce cellulase and xylanase. The anaerobic gut fungi in the camel is diverse and has cellulolytic and xylanolytic activities, fungal culture from rumen samples of camel fed wheat straw (R2) exhibited highest cellulase production. In addition, many of the sequences in the current study have no equivalent cultured representative, indicating a novel diversity within the camel gut. PMID- 30303548 TI - Lung lobe torsion in dogs: 52 cases (2005-2017). AB - OBJECTIVE: To report outcomes and risk factors for mortality in dogs that underwent surgical management of lung lobe torsion. STUDY DESIGN: Retrospective case series from 5 veterinary teaching hospitals (2005-2017). ANIMALS: Fifty dogs with 52 instances of lung lobe torsion. METHODS: Data collected from medical records included signalment, clinical findings, results of clinicopathologic testing and diagnostic imaging, surgical treatment, lung lobe affected, intraoperative and postoperative complications, histopathologic and microbiologic findings, and outcome. Follow-up was obtained from medical records and telephone contact with primary care veterinarians. RESULTS: Fifty-two instances of lung lobe torsion were identified in 50 dogs, with a median follow-up of 453 days (range, 0-3075). Forty-six (92%) dogs survived to discharge. Dogs with concurrent torsion of the right cranial and middle lung lobes were less likely to survive (2/4) than those with torsion of the left cranial lung lobe (22/22). No other risk factors for mortality prior to hospital discharge were identified. Overall median survival time after hospital discharge was 1369 days. Four dogs had >1 episode of lung lobe torsion. CONCLUSION: The percentage of dogs surviving to discharge after surgical treatment of lung lobe torsion was higher than previously reported. The short- and long-term prognosis was excellent with surgical treatment of lung lobe torsion. CLINICAL SIGNIFICANCE: Surgery should be recommended when lung lobe torsion is suspected because of the high survival to discharge rate and excellent long-term prognosis. PMID- 30303549 TI - Comparison of bleach, acetic acid, and other topical anti-infective treatments in pediatric atopic dermatitis: A retrospective cohort study on antibiotic exposure. AB - BACKGROUND/OBJECTIVES: Skin infection is common in atopic dermatitis (AD), often necessitating treatment with systemic antibiotics. Topical adjunctive therapies such as dilute bleach baths are increasingly recommended, and topical dilute acetic acid (AA) has not been widely studied. The objective of this study was to evaluate whether various topical anti-infective bathing recommendations were associated with decreased systemic antibiotic exposure in pediatric AD, as well as evaluate topical anti-infective recommendations over time within our institution. METHODS: Clinical data were extracted from charts of pediatric patients from 1/1/2000 to 12/31/2005 and 1/1/2009 to 12/31/2014 who visited outpatient dermatology clinics at Mayo Clinic, Rochester, a tertiary referral center. Recommendations for topical anti-infectives (dilute AA, dilute bleach, other, or none) at any time after patient had clinically proven or suspected AD superinfection were recorded as exposures to topical anti-infective. Primary outcome was the number of systemic antibiotic courses in a 1-year period. RESULTS: Of 1111 patients with AD, 753 met inclusion criteria (303 in 2000-2005; 450 in 2009-2014). Of these, 351 (46.6%) had culture-proven or clinically suspected superinfection. Topical anti-infective recommendations increased between the time periods (23.3% to 79.2%; P < 0.001) and number of courses of systemic antibiotics decreased (1.9 per year vs 1.5 per year, P = 0.010). Number of systemic antibiotic courses did not differ between those who received bathing recommendations and those who did not, nor between different anti-infective groups (P = 0.398). CONCLUSIONS: Practice behaviors have changed, and topical anti-infectives are now commonly recommended. Neither dilute AA nor bleach baths were associated with fewer subsequent exposures to systemic antibiotics in the treatment of pediatric AD. PMID- 30303550 TI - Mapping connectomes with diffusion MRI: deterministic or probabilistic tractography? AB - PURPOSE: Human connectomics necessitates high-throughput, whole-brain reconstruction of multiple white matter fiber bundles. Scaling up tractography to meet these high-throughput demands yields new fiber tracking challenges, such as minimizing spurious connections and controlling for gyral biases. The aim of this study is to determine which of the two broadest classes of tractography algorithms-deterministic or probabilistic-is most suited to mapping connectomes. METHODS: This study develops numerical connectome phantoms that feature realistic network topologies and that are matched to the fiber complexity of in vivo diffusion MRI (dMRI) data. The phantoms are utilized to evaluate the performance of tensor-based and multi-fiber implementations of deterministic and probabilistic tractography. RESULTS: For connectome phantoms that are representative of the fiber complexity of in vivo dMRI, multi-fiber deterministic tractography yields the most accurate connectome reconstructions (F-measure = 0.35). Probabilistic algorithms are hampered by an abundance of false-positive connections, leading to lower specificity (F = 0.19). While omitting connections with the fewest number of streamlines (thresholding) improves the performance of probabilistic algorithms (F = 0.38), multi-fiber deterministic tractography remains optimal when it benefits from thresholding (F = 0.42). CONCLUSIONS: Multi fiber deterministic tractography is well suited to connectome mapping, while connectome thresholding is essential when using probabilistic algorithms.

AB - In modern hepatology we sing the song for the advent of effective antifibrotic drugs for decades recalling the line of a masterpiece song of the late Leonard Cohen "a million candles burning for the help that never came". We realize but hardly accept that most likely such drugs will not work without resolving the causative problem of a liver disease such as in viral hepatitis. In liver diseases with so far unknown etiology as in primary sclerosing cholangitis (PSC), the task of successful antifibrotic treatment will even harder be pursued.

PMID- 30303552 TI - Effect of surgical site infection on survival after limb amputation in the curative-intent treatment of canine appendicular osteosarcoma: a Veterinary Society of Surgical Oncology retrospective study. AB - OBJECTIVE: To determine the influence of surgical site infection (SSI) on the median disease-free interval (DFI) and median survival time (MST) in dogs after amputation in the curative-intent treatment of appendicular osteosarcoma (OSA). STUDY DESIGN: Multi-institutional retrospective cohort study. ANIMALS: Fifteen dogs with OSA and SSI, and 134 dogs with OSA and no SSI. METHODS: Medical records were reviewed, and dogs were included if the following criteria were met: histologic confirmation of OSA, no evidence of metastasis, >=1 chemotherapy treatment, and available follow-up data. We used the definition of SSI from the Centers for Disease Control and Prevention. Kaplan-Meier estimates of median DFI and MST for the SSI and non-SSI groups were compared by log-rank test. Univariate and multivariate Cox proportional hazard regression analysis was evaluated for associations with DFI and survival. RESULTS: The median DFI and MST of all OSA dogs were 236 days (95% CI, 181-283) and 283 days (95% CI 237-355), respectively. The median DFI of dogs with SSI (292 days) did not differ from that of dogs without SSI (224 days, P = .156). The MST of dogs with SSI (292 days) did not differ from that of dogs without SSI (280 days, P = .417). Failure to complete chemotherapy was associated with decreased DFI and survival (P < .001). Adjustments for chemotherapy completion found no effect of SSI on survival. CONCLUSION: SSI did not influence the survival of dogs with appendicular OSA treated with amputation and curative-intent treatment. CLINICAL SIGNIFICANCE: The extended survival associated with SSI after limb-spare surgery for OSA does not appear to be present after amputation. Interactions between the canine immune system and OSA warrant additional study. PMID- 30303553 TI - Combined imaging and shimming with the dynamic multi-coil technique. AB - PURPOSE: Spatial encoding and shimming in MRI have traditionally been performed using dedicated coils that generate orthogonal spherical harmonic fields. The recently introduced multi-coil hardware has proven that MRI-relevant magnetic fields can also be created by a generic set of localized coils producing non orthogonal fields. As a step towards establishing a purely multi-coil-based MRI field generation system, the feasibility of performing conventional Cartesian k space encoding and echo-planar imaging (EPI), as well as concurrent encoding and shimming is demonstrated in this study. METHODS: We report the use of Dynamic Multi-Coil Technique (DYNAMITE) for combined Cartesian encoding and shimming, and EPI using a 48-channel multi-coil system. Experiments were performed on phantom objects and biological specimens in a 9.4 T pre-clinical scanner. Cartesian Fourier-encoded MRI and EPI were implemented whereby the magnetic fields required for encoding of the three orthogonal spatial dimensions were entirely based on linear combinations of multi-coil fields. Furthermore, DYNAMITE imaging was augmented by concurrent DYNAMITE shimming with the same hardware. RESULTS: DYNAMITE-based MR and echo-planar images were indistinguishable from those acquired with the conventional linear imaging gradients provided by the scanner. In experiments with concurrent DYNAMITE shimming and imaging, shim challenges that would result in extreme spatial distortion and signal loss were corrected very effectively with more than 92% signal recovery in case of extreme Z2 shim challenge that resulted in complete signal dephasing in most slices. CONCLUSIONS: We demonstrate the first successful implementation of combined DYNAMITE imaging and shimming and show the feasibility of performing EPI with DYNAMITE hardware. Our results substantiate the potential of multi-coil hardware as a full-fledged imaging and shimming system, with additional potential benefits of reduced echo time and risk of peripheral nerve stimulation while performing EPI. PMID- 30303554 TI - Expression and polymorphism of micro-RNA according to body mass index and breast cancer presentation in Tunisian patients. AB - Micro-RNAs (miRs) constitute a class of small noncoding RNAs implicated in the regulation of gene expression by binding to target mRNAs. A miR can target several mRNAs, being involved in different biologic processes and pathologies. This pleiotropic function might explain the link between diseases co-occurrence. Epigenetic origin of the link between obesity and breast cancer (BC) is investigated in a cohort of Tunisian patients, focusing on polymorphism at germline level (miR-146a) and on expression in mammary tumors (miR-21, miR-146a, and miR-34a), according to body mass index (BMI) and clinico-pathologic features. The measure of miR expression in 60 mammary tumors was realized using quantitative RT-PCR. Study of rs 2910164 in miR-146a was performed by PCR and direct sequencing using blood DNA of 83 affected women and 50 unrelated subjects from Great Tunis. MiR-21, miR-146a, and miR-34a have been quantified in breast tumor according to BMI. MiR-21 is significantly more expressed in tumors of obese women comparatively to nonobese patients. On the contrary, miR-34a is decreased in tumors of obese women. Moreover, in obese BC patients, a significant increase in both miR-21 and miR-146a expression is revealed in cases with lymph node metastasis. The polymorphism at rs 2910164 (miR-146a) locus was not shown as a risk factor for BC. However the mutant CC genotype was revealed to be associated with a risk for bad outcome of the disease. Chronic inflammation in obese women would be linked to aggressive breast tumors via induction of oncomiRs overexpression and decrease of tumor suppressor miRs. PMID- 30303555 TI - Gait biomechanics after combined HTO-ACL reconstruction versus HTO alone: A matched cohort study. AB - The purpose of the present study was to compare bilateral external knee moments during gait in patients with concomitant medial compartment knee OA, varus alignment and chronic anterior cruciate ligament (ACL) deficiency who underwent either medial opening-wedge high tibial osteotomy alone (HTO) or simultaneous HTO and ACL reconstruction (HTO-ACLR). Fifty-two patients (26 matched pairs) completed 3D gait analysis preoperatively and at a minimum 5 years postoperatively. Patients were matched for preoperative age, sex, body mass index and magnitude of correction. Primary outcomes selected a priori were the peak knee adduction moment (KAM) and knee flexion (KFM) moment during stance. Moments were compared using mixed model repeated measures analysis of variance (ANOVA). For the peak KAM, there was a significant time by limb interaction. For both groups, there were similar reductions in the peak KAM 5 years postoperatively in the surgical limb only [-1.34 %BW * Ht (-1.71, -0.96) and -1.72 %BW * Ht (-1.99, 1.44) for HTO and HTO-ACLR, respectively]. For the peak KFM, there was a significant time by group by limb interaction. There was a decrease in the peak KFM 5 years postoperatively in the HTO group [-0.88 %BW * Ht (-1.45, -0.31)] but not in the HTO-ACLR group [0.03 %BW * Ht (-0.43, 0.48)]. These results suggest that individuals with medial knee OA, varus alignment and chronic ACL deficiency who undergo simultaneous medial opening-wedge HTO and ACL reconstruction may not experience the same long-term (5 year) changes in sagittal plane knee biomechanics observed in patients undergoing HTO alone.

PMID- 30303556 TI - Solution dynamics of 5-fluorouracil entrapped in poly lactic-co-glycolic acid (PLGA) microsphere-A study with 1D selective NMR methods. AB - In this report, our main focus is to introduce a set of one-dimensional (1D) NMR methods based on chemical shift, relaxation, and magnetization transfer, namely, NOE and chemical exchange involving selective pulse excitation to study the solution dynamics of drug in free and encapsulated state within polymeric microsphere. In this regard 5-fluorouracil (5-FU) loaded poly lactic-co-glycolic acid (PLGA) microspheres are prepared as model system via standard water-in-oil in-water emulsification method. One-dimensional 1 H and 19 F nuclear magnetic resonance (NMR) spectra of 5-FU in presence of PLGA microspheres presented a significant change in linewidth and relaxation rates compared with free 5-FU confirming encapsulation. Furthermore, loss of coupling pattern in 1 H and 19 F NMR of PLGA encapsulated 5-FU as compared with free 5-FU suggests an enhanced -NH and -H2 O protons exchange dynamics in the interior of the microsphere indicating hydrated microsphere cavity. Quantification of exchange dynamics in case of free and PLGA-encapsulated 5-FU was attempted employing 1D selective NOESY and 1D multiply selective inversion recovery experiments. Analysis of the exchange rates confirmed existence of more than one kind of water population within the cavity as mentioned in an earlier solid state NMR report. PMID- 30303557 TI - A comparison of international management guidelines for atopic dermatitis. AB - BACKGROUND/OBJECTIVES: Atopic dermatitis (AD) is a chronic condition that is predominantly found in pediatric patients and commonly presents therapeutic challenges. The management of AD encompasses a variety of factors, and the pillars of optimal management revolve around skin barrier repair and antiinflammatory, antimicrobial, and antipruritic treatment. AD management guidelines exist in various geographic regions globally. The purpose of this review was to compare international guidelines to highlight the similarities and variances among populations and skin types. Comparisons were made for recommendations regarding moisturization, bathing, wet wrap therapy, topical corticosteroids, topical calcineurin inhibitors, antihistamines, antipruritics, antibiotics, systemic immunosuppressants, and biologics. METHODS: A literature search of the PubMed, EMBASE, and MEDLINE databases was performed for published guidelines in each geographic region. Inclusion criteria included publications available in English that were established by a dermatological association or group including dermatologists, pertained to the treatment of AD in humans, were the most recent guidelines available that were published between 2007 and 2018, and included comprehensive treatment recommendations. RESULTS: Publications from Europe, North America, Asia, the Asia-Pacific region, Australia, and Africa were reviewed, encompassing 14 guidelines. Notable diversity exists across these guidelines regarding recommendations for moisturization and bathing, as well as topical and systemic therapies for AD. CONCLUSIONS: Due to the heterogeneity of the disease and regional treatment accessibility, complete standardization of AD management guidelines may be difficult. Nevertheless, more consensus on management guidelines is needed, and recommendations should be updated as new treatment modalities become available.

AB - We report a case of successful treatment of a traumatic tattoo in a 2-year-old patient.

A single treatment with an alexandrite picosecond laser resulted in a complete clearance without any side effects for this disfiguring condition. PMID- 30303559 TI - Effect of pH on Cr(III) accumulation, biomass production, and phenolic profile in 2 Salvinia species. AB - We analyzed the effect of pH on Cr(III) accumulation, biomass production, and phenolic profile of Salvinia rotundifolia and Salvinia minima plants grown in the presence of increasing concentrations of CrCl3 . Biomass accumulation, metal tolerance index, and photosynthetic pigment contents indicate that Salvinia rotundifolia seems to be more tolerant of Cr(III) than S. minima at different pHs. Increased metal accumulation by Salvinia species under increasing pH could be explained by changes of the protonation status of cell wall functional groups because both the highest and the lowest pH values used in the present study were outside of the levels at which Cr(III) species start to precipitate. The metal translocation factor indicates that in buffered conditions S. rotundifolia tend to retain more Cr(III) in lacinias than S. minima, probably through the involvement of insoluble phenolics. The results of the present study could be useful to the management of solution pH to maximize the removal of Cr(III) by aquatic plants. Environ Toxicol Chem 2018;9999:1-10. (c) 2018 SETAC. PMID- 30303560 TI - Chemical biofilm removal capacity of endodontic irrigants as a function of biofilm structure: optical coherence tomography, confocal microscopy and viscoelasticity determination as integrated assessment tools. AB - AIM: To investigate the influence of biofilm structure on the biofilm removal capacity of endodontic irrigants and to study changes in the architecture of the remaining biofilms. METHODOLOGY: Streptococcus oralis J22 and Actinomyces naeslundii T14V-J1 were cocultured under different growth conditions on saliva coated hydroxyapatite discs. A constant depth film fermenter (CDFF) was used to grow steady-state 4-day biofilms. Biofilms were grown under static conditions for 4 and 10 days within a confined space. Twenty microlitres of 2% NaOCl, 2% Chlorhexidine (CHX), 17% Ethylene-diamine-tetra-acetic acid (EDTA) and buffer were applied statically on the biofilms for 60 s. Biofilm removal was evaluated with optical coherence tomography (OCT). Post-treated biofilms were assessed via low load compression testing (LLCT) and Confocal laser scanning microscopy (CLSM). Optical coherence tomography data were analysed through a two-way analysis of variance (ANOVA). Low load compression testing and CLSM data were analysed through one-way ANOVA and Dunnett's post hoc test. The level of significance was set at a < 0.05. RESULTS: The initial biofilm structure affected the biofilm removal capacity of the irrigants. NaOCl demonstrated the greatest chemical efficacy against the biofilms and was significantly more effective on the static than the CDFF biofilms (P < 0.001). CHX was ineffective and caused a rearrangement of the biofilm structure. Ethylene-diamine-tetra-acetic acid exhibited a distinct removal effect only on the CDFF biofilms. Biofilm age influenced the structure of the remaining biofilms. The 4-day grown remaining biofilms had a significantly different viscoelastic pattern compared to the respective 10-day grown biofilms (P <= 0.01), especially in the NaOCl-treated group. Confocal laser scanning microscopy analysis confirmed the CHX-induced biofilm structural rearrangement. CONCLUSIONS: Biofilm structure is an influential factor on the chemical efficacy of endodontic irrigants. Optical coherence tomography allows biofilm removal characteristics to be studied. NaOCl should remain the primary irrigant. Ethylene-diamine-tetra-acetic acid was effective against cell-rich/EPS-poor biofilms. Chlorhexidine did not remove biofilm, but rather rearranged its structure. PMID- 30303561 TI - Neuroendocrine proliferations in inflammatory bowel disease: differentiating neuroendocrine tumours from neuroendocrine cell micronests. AB - AIMS: A wide spectrum of well-differentiated neuroendocrine proliferations (NEPs) are observed in inflammatory bowel disease (IBD), ranging from neuroendocrine tumours (NETs) to microscopic neuroendocrine cell clusters, best described as neuroendocrine cell micronests (NCMs). Finding NCMs in surveillance biopsies of IBD patients often poses a diagnostic conundrum. While such lesions may have been referred to as 'microcarcinoids' in the literature, it is unclear whether these represent early neoplasms. The study was undertaken to characterise NCMs and to differentiate NCMs from NETs. METHODS AND RESULTS: Institutional surgical pathology archives were searched to identify cases of NEPs in IBD patients. Clinicopathological features were examined. NCMs were defined as scattered, indistinct neuroendocrine cell clusters without confluent growth or new stroma formation, located in the lamina propria and muscularis mucosae. NETs were defined as discrete, mass-forming lesions. Seventeen NEPs were identified, including eight NCMs and nine NETs. All NEPs were incidentally discovered. While NETs were commonly found in the rectum and appendix, NCMs were only noted in the rectosigmoid area. Unlike NETs, NCMs could not be measured as a discrete lesion as these clusters were non-confluent and scattered. None of the patients with NCMs developed NETs after a mean follow-up of 4.1 years (range = 0.5-21.0 years). None of the NETs showed NCMs in the background mucosa. CONCLUSIONS: NCMs have distinct pathological features, are not associated with NETs in IBD patients and should not be misinterpreted as 'microcarcinoids'. Identification of NCMs in surveillance biopsies may not require further clinical work-up or invasive procedures usually performed for NETs. PMID- 30303562 TI - On the accuracy and precision of PLANET for multiparametric MRI using phase cycled bSSFP imaging. AB - PURPOSE: In this work we demonstrate how sequence parameter settings influence the accuracy and precision in T1 , T2 , and off-resonance maps obtained with the PLANET method for a single-component signal model. In addition, the performance of the method for the particular case of a two-component relaxation model for white matter tissue was assessed. METHODS: Numerical simulations were performed to investigate the influence of sequence parameter settings on the accuracy and precision in the estimated parameters for a single-component model, as well as for a two-component white matter model. Phantom and in vivo experiments were performed for validation. In addition, the effects of Gibbs ringing were investigated. RESULTS: By making a proper choice for sequence parameter settings, accurate and precise parameter estimation can be achieved for a single-component signal model over a wide range of relaxation times at realistic SNR levels. Due to the presence of a second myelin-related signal component in white matter, an underestimation of approximately 30% in T1 and T2 was observed, predicted by simulations and confirmed by measurements. Gibbs ringing artifacts correction improved the precision and accuracy of the parameter estimates. CONCLUSION: For a single-component signal model there is a broad "sweet spot" of sequence parameter combinations for which a high accuracy and precision in the parameter estimates is achieved over a wide range of relaxation times. For a multicomponent signal model, the single-component PLANET reconstruction results in systematic errors in the parameter estimates as expected. PMID- 30303563 TI - Radiosynthesis of an 18 F-fluoroglycosylated aminoferrocene for in-vivo imaging of reactive oxygen species activity by PET. AB - The imaging of reactive oxygen species (ROS) at the molecular level with high sensitivity and specificity by positron emission tomography (PET) could be of enormous interest to increase our knowledge about ROS activity and signalling, especially in tumours. The aim of this research was to optimise the click chemistry-based radiosynthesis of an 18 F-labelled aminoferrocene glycoconjugate that was derived from an N-alkylaminoferrocene lead structure known to have anticancer activity in vitro. Applying the solvent system phosphate buffer/THF (12/5), Cu(OAc)2 and sodium ascorbate as reducing agent at 60 degrees C, the alkyne 1 reacted with the 18 F-labelled glycosyl azide [18 F]2 in the presence of carrier 3 (47MUM) to obtain carrier-added [18 F]4 in a radiochemical yield of 85%. Interestingly, the addition of carrier was essential for sufficient radiochemical yield, because it suppressed the oxidation of no-carrier-added (n.c.a.) [18 F]4. Future work will include the formulation of c.a. [18 F]4 for studying its biodistribution in tumour-bearing mice. PMID- 30303564 TI - Lesion segmentation for MR spectroscopic imaging using the convolution difference method. AB - PURPOSE: Delineation of lesion boundaries from volumetric MRSI metabolite ratio maps using a method that accounts for the spatial response function of the acquisition and variable spectral quality and is robust to signal heterogeneity within the lesion. METHODS: A novel method for lesion segmentation, termed convolution difference, has been developed that is robust to signal heterogeneity within the lesion and to differences in the spatial response function. Procedures are described for processing metabolite ratio maps and to exclude regions of inadequate spectral quality. This method was evaluated using computer simulations, and the results were compared with an iterative thresholding technique that determines an optimal amplitude threshold, and with the use of a fixed amplitude threshold. These methods were evaluated for segmentation of volumetric MRSI studies of gliomas using maps of the choline to N-acetylaspartate ratio, and a qualitative comparison of lesion volumes carried out. RESULTS: Simulation studies indicated improved performance for the convolution difference method when applied to ratio maps. Variations in tumor volume were observed for the in vivo studies between the convolution difference and the iterative thresholding methods; however, visual analysis indicates that both showed improved accuracy in comparison to using a fixed amplitude threshold. CONCLUSION: This study reinforces previous reports indicating that the use of fixed threshold values for segmentation of maps with broad spatial response functions can result in errors in lesion volume definition. A novel segmentation method, termed the convolution difference, has been introduced and demonstrated to be robust for segmentation of volumetric MRSI metabolite data.

AB - Undifferentiated pleomorphic sarcoma (UPS) is the second most frequent soft tissue sarcoma. Because of its resistance to chemotherapy, UPS patients are treated with surgical resection and complementary radiotherapy. However, since standard chemotherapy has not been established, unresectable or metastatic cases result in a poor prognosis. Therefore, the identification of a more effective therapy for UPS patients is needed. The development and progression of malignant tumors involve epigenetic alterations, and histone deacetylases (HDAC) have become a promising chemotherapeutic target. In this study, we investigated the potential effects and mechanisms of an HDAC inhibitor, LBH589, in UPS cells. We confirmed that LBH589 exhibits potent antitumor activities in four human UPS cell lines (GBS-1, TNMY-1, Nara-F, and Nara-H) and IC50 values ranged from 7 to 13 nM. A mouse xenograft model showed that LBH589 treatment effectively suppressed tumor growth. FACS analysis showed that LBH589 induced apoptosis and G2/M cell cycle arrest. Among apoptosis-related proteins, the expressions of Bcl-2 and Bcl-xL were decreased and the expression of Bak and Bim increased. Among cell cycle related proteins, reductions of CDK1, p-CDK1, cyclin B1, Aurora A, and Aurora B were observed after LBH589 treatment. RNA microarray identified the FOS-like antigen 1 (FOSL1) gene as a downregulated gene in response to LBH589 in UPS cells. While knockdown of FOSL1 decreased UPS cell proliferation, overexpression induced cell proliferation. Our results show that LBH589 could be a promising chemotherapeutic agent in the treatment of UPS and downregulation of the FOSL1 gene could be the new molecular target of UPS treatment. PMID- 30303566 TI - The utility of the Milan System as a risk stratification tool for salivary gland fine needle aspiration cytology specimens. AB - OBJECTIVE: To perform a retrospective investigation of our institutional experience with salivary gland fine needle aspirations (FNA) through the framework of The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) and assess the risks of neoplasm and malignancy for each diagnostic category. METHODS: All salivary gland FNAs performed from January 2009 to December 2016 were retrospectively categorised according to the MSRSGC. When available, pre operative cytological results were correlated with subsequent histological follow up. RESULTS: In total, 893 FNAs were reviewed. The specimens were retrospectively classified as nondiagnostic (ND: 13.5%), non-neoplastic (NN: 16.1%), atypia of undetermined significance (AUS: 10.8%), benign neoplasm (BN: 34.9%), salivary gland neoplasm of uncertain malignant potential (SUMP: 8.2%), suspicious for malignancy (SM: 2.7%) and malignant (M: 13.8%). Histological follow-up was available for 429 cases (48%); the majority (68.1%) were benign. The risks of neoplasm and malignancy for each category were as follows: ND: 64.5%, 16.1%; NN: 42.9%, 17.9%; AUS: 79.6%, 30.6%; BN: 100%, 2.2%; SUMP: 100%, 46.6%; SM: 94.7%, 78.9%; and M: 100%, 98.5%. CONCLUSIONS: The MSRSGC is a useful classification scheme for stratifying salivary gland lesions according to their associated risk of malignancy and guiding clinicians toward appropriate management. Diagnostic pitfalls are seen in a small proportion of cases and a multidisciplinary approach for assessing salivary gland pathology is essential in their evaluation. PMID- 30303567 TI - Changes in neurosteroidogenesis during demyelination and remyelination in cuprizone-treated mice. AB - Changes of neurosteroids may be involved in the pathophysiology of multiple sclerosis (MS). The present study investigated whether changes of neurosteroidogenesis also occurred in the grey and white matter regions of the brain in mice subjected to cuprizone-induced demyelination. Accordingly, we compared the expression of neurosteroidogenic proteins, including steroidogenic acute regulatory protein (StAR), voltage-dependent anion channel (VDAC) and 18 kDa translocator protein (TSPO), as well as neurosteroidogenic enzymes, including the side chain cleavage enzyme (P450scc), 3beta-hydroxysteroid dehydrogenase/isomerase and 5alpha-reductase (5alpha-R), during the demyelination and remyelination periods. Using immunohistochemistry and a quantitative polymerase chain reaction, we demonstrated a decreased expression of StAR, P450scc and 5alpha-R with respect to an increase astrocytic and microglial reaction and elevated levels of tumor necrosis factor (TNF)alpha during the cuprizone demyelination period in the hippocampus, cortex and corpus callosum. These parameters, as well as the glial reaction, were normalised after 2 weeks of spontaneous remyelination in regions containing grey matter. Conversely, persistent elevated levels of TNFalpha and low levels of StAR and P450scc were observed during remyelination in corpus callosum white matter. We conclude that neurosteroidogenesis/myelination status and glial reactivity are inversely related in the hippocampus and neocortex. Establishing a cause and effect relationship for the measured variables remains a future challenge for understanding the pathophysiology of MS. PMID- 30303568 TI - Assessment of perioperative surgical complications in pediatric kidney transplantation: A comparison of pre-emptive and post-dialysis recipients. AB - PURPOSE: To determine whether there is a benefit to pre-emptive kidney transplantation in reducing surgical complications in pediatric population. METHODS: A retrospective review of kidney transplantations in our institution from 2000 to 2015 was performed. Intra- and postoperative complication rates and one-year graft survival were compared in their respective donor type groups (pre emptive DD vs post-dialysis DD; pre-emptive LD vs post-dialysis LD). RESULTS: A total of 318 patients were identified (pre-emptive DD, n = 21; post-dialysis DD, n = 145; pre-emptive LD, n = 54; post-dialysis LD, n = 98). Between the DD groups, post-dialysis DD group was more likely to be female (P = 0.017). There was no difference in rates of intraoperative complications or graft loss (P = 0.365 and 1.000, respectively). Post-dialysis DD groups were more likely to have postoperative complications (9.5% vs 35.1%, P = 0.023), but no difference in complications with Clavien-Dindo grade 3 or higher was found (P = 0.130). Between the LD groups, post-dialysis LD group was more likely to be females (P = 0.017) and with intrinsic renal (non-urological/structural) ESRD etiology (P = 0.003). There was no difference in rates of intra-and postoperative complications or graft loss (P = 0.353, P = 0.605, and P = 0.616, respectively). CONCLUSIONS: Overall, there are similar perioperative complication rates between pediatric pre emptive and post-dialysis kidney transplant recipients.
